Opis:
Purpose: To evaluate the risk and prognostic factors of post-catheterization pseudoaneurysm (PPA). Material and methods: To identify the risk factors for PPA occurrence, clinical findings were compared between 22 consecutive patients with radiologically confirmed PPAs (PPA group) and 300 randomly extracted patients without PPA, who underwent transarterial angiography or intervention (sample group) between 1 January 2015 and 31 March 2020. The PPA group was further divided into those treated successfully with mechanical compression (group A) and those requiring ultrasound-guided thrombin injection after compression failed (group B). Univariate and multivariate analyses were used to compare patient demographics, preoperative laboratory findings, procedure details, PPA diameter, and time interval between the procedure and compression between groups A and B to evaluate the prognostic factors of PPA. Results: The PPA group demonstrated significantly elevated prothrombin time international normalized ratios (PT/INR) (odds ratio [OR]: 6.27, 95% confidence interval [CI]: 2.020-19.5; p = 0.00151) and more frequent popliteal access (OR: 14.2, 95% CI: 1.040-195.0; p = 0.0467) compared to the sample group, and radial access decreased the risk of PPA (OR: 0.382, 95% CI: 0.0148-0.987; p = 0.0468). One of the 22 PPAs resolved spontaneously, and 11 others (52.4%) were successfully treated by mechanical compression. An interval exceeding 24 hours between the procedure and compression was the only significant prognostic factor (p = 0.0281) between groups A and B. Conclusions: Elevated PT/INR and popliteal access may predispose patients to PPA; close consideration of the site of access may lower the risk of refractory PPA.

Opis:
Besides clinical medicine, which is in the process of constant and fast development, the focus is increasingly on public health services, which should be well prepared for reducing or keeping under control the dangers induced by the growing social burden of disease. Continuous risk management is represented by these services that are specially designed to prevent diseases and health damages. The grounds for the planning and implementation of public health services are constituted by risk factor management and assessment by means of adopting a unified approach. The organisation as well as the cost-effective implementation of services – providing primary, secondary and tertiary prevention – on community and individual levels will be of utmost importance in the future, and will mean, besides risk equalisation, adopting a unified approach as to the provision of public health services.

Opis:
Stress is considered to be both a trigger of autoimmune diseases and a factor which contributes to disease exacerbation. Emotional stress before the disease onset is reported by up to 80% of patients suffering from autoaggressive diseases. A significant increase in the prevalence of autoimmune diseases in recent years and the growing number of stressors in our daily lives, including the work environment, raise a question about a link between psychological stress and autoimmune disorders. Therefore, the objective of this paper is to highlight the potential role of stress in both development and exacerbation of autoimmune diseases. The potential mechanisms by which stress can affect autoimmunity are characterised. In particular, the focus is on rheumatic diseases, autoimmune endocrine disorders, multiple sclerosis, and psoriasis. In addition, the role of post-traumatic stress disorder is underlined, as well as the possible association between stress present in the work environment and the development of autoimmune diseases among employees.
Stres jest uważany zarówno za czynnik spustowy dla chorób autoimmunologicznych jak i przyczyniający się do ich zaostrzenia. Stres emocjonalny, występujący przed pojawieniem się choroby, zgłasza nawet do 80% pacjentów cierpiących na choroby z autoagresji. Znaczący wzrost zachorowalności na choroby autoimmunologiczne oraz rosnąca liczba czynników stresogennych w naszym codziennym życiu, w tym w środowisku pracy, stawia pytanie o związek pomiędzy stresem psychicznym a chorobami autoimmunologicznymi. Dlatego też celem artykułu jest naświetlenie możliwej roli stresu w rozwoju i zaostrzeniach chorób autoimmunologicznych. Scharakteryzowano potencjalne mechanizmy, za pomocą których stres może oddziaływać na autoimmunizację. W szczególności skupiono się na chorobach reumatologicznych, zaburzeniach endokrynologicznych, stwardnieniu rozsianym oraz łuszczycy. Dodatkowo podkreślono rolę stresu pourazowego jak i możliwych związków pomiędzy stresem w środowisku pracy a rozwojem chorób autoimmunologicznych wśród pracowników.

Opis:
The problem of burns is relatively a common issue in many developing and developed countries. Most burns occur at home, so the home environment plays an important role in these injuries. Considerable attention has been recently paid to environmental factors such as socioeconomic including family, living conditions and their influence on frequency of burns. This manuscript reviews papers published in the last few years to show if environmental factors influence the risk of burns in children. The researchers point to the relationship between age, education of parents, number of siblings, home environment and the frequency of burns in children. Identification of risk factors plays an important role in planning preventable measures.
Tematyka oparzeń u dzieci wciąż jest aktualna zarówno w krajach rozwijających się, jak i rozwiniętych. Do większości tego typu urazów dochodzi w domu, więc środowisko domowe może odgrywać istotną rolę w ich powstaniu. Ostatnio znaczną uwagę zwrócono na czynniki środowiskowe, takie jak czynniki socjoekonomiczne, w tym rodzinne, oraz warunki życia i ich wpływ na częstość oparzeń. W pracy dokonano analizy piśmiennictwa z kilku ostatnich lat poruszającego temat wpływu czynników środowiskowych na ryzyko oparzeń u dzieci. Przeprowadzone badania wskazują na związek pomiędzy wiekiem, wykształceniem rodziców, liczbą rodzeństwa oraz warunkami mieszkaniowymi a częstością oparzeń u dzieci. Zidentyfikowanie tych czynników ma istotne znaczenia dla planowania działań profilaktycznych.

Opis:
Objectives: In addition to being a serious health-hazard, substance-use-and-misuse (SUM) in military forces negatively infl uences physical fi tness and army readiness. The aim of this study was to defi ne the prevalence of SUM, which includes cigarette smoking, alcohol consumption, and multiple SUM (i.e. practice of daily smoking and harmful alcohol drinking), and factors infl uencing SUM in the Croatian Special Army Forces (SAF). Materials and Methods: We studied 73 SAF members. A self-administered validated questionnaire was used to gather socio-demographic and military-professionrelated data, and SUM factors. The associations between studied variables were established by the Chi² test, and forward conditional logistic regression (FCLR). Results: With less than 40% of daily smokers, smoking was within expected values. Almost 80% of the examinees reported no binge drinking, while 54% reported harmful drinking according to the Alcohol Use Disorders Identifi cation Test scale. Paternity and education level were negatively associated with daily smoking, while higher incidence of daily smoking was found for privates and those who practiced harmful drinking (all at p < 0.05). The FCLR demonstrated a higher risk of harmful alcohol consumption for younger commissioned offi cers (OR for military rank = 5.54, 95% CI: 2.19-13.99; OR for age = 0.85, 95% CI: 0.76-0.95). Conclusion: Although SUM incidence was not alarming compared to the overall population and the previously reported military data, additional efforts are necessary in order to decrease cigarette consumption. The study showed that protective/risk structure of the substance misuse in the military should be investigated specifi cally with regard to particular military services, corps, and socio-cultural environment.

Problem. Prevalence of traumatic stress in general population is not so often but in some vocations it is a serious risk factor for employees’ health. A traumatic event is a main reason for PTSD and other mental disorders. There are multiple risk factors for PTSD development but the exposure to traumatic event is a main cause, included in a definition of PTSD. A need of stimulation, strongly connected to reactivity, may be treated as an individual resource because it let diminishing a chance of PTSD development but it may be treated as the risk factor of this disorder also. Hypothesis. Number of exposures to traumatic events is correlated to power of stimulation need. Subjects. 109 soldiers. Methods. Sensation Seeking Scale (SSS) by M. Zuckerman and Stressful Life Events Questionnaire (experimental version by M. Lis-Turlejska). Results. Relationships between results obtained in the particular dimension of the stimulation need and the number of traumatic events experienced by subjects are as follow: a dimension of thrill and adventure seeking (TAS) – rho = 0.30 (p < 0.008); an experience seeking dimension (ES) – rho = 0.20 (p < 0.060); a disinhibition dimension (DIS) – rho = 0.30 (p < 0.008) a boredom susceptibility dimension (BS) – rho = 0.20 (p < 0.060); a general dimension of stimulation seeking (G) – rho = 0.10 (p < 0.210). Rank correlation between a total results of SSS (a sum of subscales results) and the number of traumatic events experienced by the subjects is 0,25 (p < 0,008).

Opis:
Background: Hemodialysis used as renal replacement therapy requires a well-functioning vascular access. Arterio-venous fistula (AVF) created on the forearm is the best vascular access, but it also reveals numerous complications such as: lack of fistula maturation and hemodynamically significant stenoses. Many risk factors of fistula dysfunction are still not identified. Material/Methods: Radial artery and cephalic vein diameter and patency were ultrasonographically examined before forearm AVF creation. Intima-media complex width, blood flow and peak systolic velocity in distal part of radial artery were measured. Presence of thrombosis and post-inflammatory changes in cephalic vein were also checked. Forearm AVF was created in 66 patients. Fistula US examination was performed 3 and 12 months after operation with measurement of vessel diameter and blood flow. Fistula patency was observed in 24 months after creation. Comparison of pre- and postoperative US examinations between groups with well functioning and thrombosed fistulas was performed. Results: Primary patency of forearm AVF after 12 and 24 months was 65.2% and 53.0%, respectively. Patients with well functioning forearm AVF have significantly bigger cephalic vein diameter and peak systolic velocity in radial artery. We did not observe significant influence of radial artery intima-media complex width and radial artery diameter on AVF function. In postoperative examination, fistula diameter and flow significantly influenced the risk of AVF thrombosis. Conclusions: US examination of radial artery and cephalic vein performed before forearm AVF creation enables identification of patients with greater risk of fistula dysfunction. Cephalic vein diameter and peak systolic velocity are prognostic factors of fistula function. Control postoperative US examination of forearm fistula enables detection of AVF at risk of thrombosis.

Opis:
A patient’s compliance to a physician’s lifestyle information is essential in chronic coronary syndrome (CCS) patients. We assessed potential characteristics associated with a patient’s recollection of physician information and lifestyle changes. This study recruited and interviewed patients (aged ≤ 80 years) 6–18 months after hospitalization due to acute coronary syndrome or elective myocardial revascularization. A physician’s information on risk factors was recognized if patients recollected the assessment of their diet, weight management, blood pressure control, cholesterol level, diabetes, and other lifestyle factors by the doctor. Of a total of 946 chronic coronary syndrome patients, 52.9% (501) of them declared the recollection of providing information on more than 80% of the risk factors. A good recollection of risk factor information was associated with the following: a patient’s age (OR per year: 0.97; 95% CI: 0.95 to 0.99), obesity (OR: 4.41; 95% CI: 3.09–6.30), diabetes (OR: 4.16; 95% CI: 2.96–5.84), diuretic therapy (OR: 1.41; 95% CI: 1.03–1.91), calcium channel blockers (OR: 1.47; 95% CI: 1.04–2.09), and ACEI/sartan (OR: 0.65; 95% CI: 0.45–0.94) at hospitalization discharge. In terms of goal attainment, better adherence to antihypertensive drugs (OR: 1.80; 95% CI: 1.07–3.03) was observed in the patients with a good compared to a poor recollection of risk factor information. The recollection of physician risk factor information was significantly associated with more comorbidities. Strategies to tailor the conveying of information to a patient’s perception are needed for optimal patient–doctor communication.

Opis:
Objective: While artisanal mining takes place in casual framework and with total ignorance of good practices, few studies have focused on the origin of hazards specific to each workplace constitutive of this exploitation facility. Nevertheless, this study is a condition of an efficient occupational health and safety control in this sector. Materials and Method: We took the effort to identify different workplaces, as well as hazards specific to each of them, through the observation and analysis of the tasks, tools and the processes related to their use applied in the Ruashi artisanal mine. Results: The investigated exploitation facility consists of five workplaces: diggers (60% – in charge of mineralized gangue recovery); crushers; washers; hand-made furnace workers (in charge of various treatment processes); and loaders (in charge of packing the obtained material). Beside the risks common to these various workplaces and ensuing notably from the lack of hygiene and working in bad positions, operating in underground galleries, in particular, exposes diggers to the risks connected with collapsing parts of the mine, suffocation, dehydration or fine particles in the breathed air. Crushers are especially exposed to traumatism risks, notably ocular, and loaders are exposed to risks related to handling heavy loads. These risks are connected with the mining processes because, in spite of the similarity of tools, they appear less often in other forms of artisanal exploitation described in literature. It is notable in the case of crushing in sawed gas bottles where ocular trauma risk is decreased. It was also shown that humidification of work surface reduces dust particles emission into the air. Conclusions: Hazards identification, through a tools and processes description, has the advantage of providing information on reducing the occurrence of these risks. It shows that this reduction is not necessarily a consequence of the activity mechanization degree.

Opis:
Recent literature data suggests that parasitic and fungal diseases, which pose a threat to both human and animal health, remain a clinical, diagnostic and therapeutic problem. Attention is increasingly paid to the role played by natural microbiota in maintaining homeostasis in humans. A particular emphasis is placed on the possibility of manipulating the human microbiota (permanent, transient, pathogenic) and macrobiota (e.g., Trichuris suis) to support the treatment of selected diseases such as Crohn’s disease, obesity, diabetes and cancer. Emphasis is placed on important medical species whose infections not only impair health but can also be life threatening, such as Plasmodium falciparum, Echinococcus multilocularis and Baylisascaris procyonis, which expand into areas which have so far been uninhabited. This article also presents the epidemiology, diagnosis and treatment of opportunistic parasitoses imported from the tropics, which spread across large groups of people through human-to-human transmission (Enterobius vermicularis, Sarcoptes scabiei). It also discusses the problem of environmentally-conditioned parasitoses, particularly their etiological factors associated with food contaminated with invasive forms (Trichinella sp., Toxoplasma gondii). The analysis also concerns the presence of developmental forms of geohelminths (Toxocara sp.) and ectoparasites (ticks), which are vectors of serious human diseases (Lyme borreliosis, anaplasmosis, babesiosis), in the environment. Mycological topics contains rare cases of mycoses environmentally conditioned (CNS aspergillosis) and transmissions of these pathogens in a population of hospitalized individuals, as well as seeking new methods used to treat mycoses.

Opis:
The paper presents a general overview of risk factors in gynaecological oncology based on a review of recent literature, highlighting their role in preventive medicine. Since mid-twentieth century the role of risk factors is being increasingly appreciated, particularly those directly associated with the risk of developing certain diseases, including female genital malignancies. Several risk factors have been defined, e.g. genetic, biologic, socioeconomic, cultural, geographic, iatrogenic and environmental and their list is ever increasing. This has made possible the definition of high-risk groups of women, who require close medical monitoring in order to detect neoplastic disease at an earliest possible stage. Risk factors usually precede the process of carcinogenesis, although both may be synchronous. Risk factors have various prognostic values: one risk factor may be present in several different neoplasms and several different risk factors may be associated with a single tumour. A frequent phenomenon is oncological synergy. Most female genital neoplasms are multifactorial diseases.
Opierając się na przeglądzie piśmiennictwa ostatnich lat, przedstawiono ogólne wiadomości o czynnikach zagrożenia w ginekologii onkologicznej, podkreślając ich znaczącą rolę w medycynie zapobiegawczej. Począwszy od lat 50. XX w., przywiązywano dużą wagę do czynników ryzyka wskazujących na możliwość wystąpienia zagrożenia powstania choroby, w tym również nowotworów narządów płciowych u kobiet. Wykryto wiele czynników zagrożenia począwszy od genetycznych, poprzez biologiczne, socjoekonomiczne, kulturowe, geograficzne, jatrogenne, a skończuwszy na środowiskowych i lista ta jest ciągle uzupełniana. Dało to podstawy do wyodrębnienia spośród populacji kobiet grup podwyższonego ryzyka wymagających wzmożonej kontroli medycznej, co z kolei pozwalało na wykrycie choroby nowotworowej we wczesnym etapie jej rozwoju. Czynniki zagrożenia na ogół poprzedzają proces kancerogenezy, choć mogą też w nim uczestniczyć. Przedstawiają one różną wartość kliniczną: jeden czynnik zagrożenia może występować w wielu nowotworach, a wiele czynników - w jednej chorobie nowotworowej; często występuje synergizm onkologiczny. Większość nowotworów narządów płciowych to tzw. „choroby wieloczynnikowe”.

Opis:
El Fuerte de Samaipata is a pre-Hispanic archaeological site in Bolivia that has been on the UNESCO World Heritage List. Its main part – the rock – is densely covered with a complex arrangement of terraces, platforms, water reservoirs, channels, and petroglyphs. The rapidly progressing erosion of the rock is making the petroglyphs less and less clear, and some are no longer recognisable. The main topic of this study is to indicate all risk factors conducive to erosion and to create risk maps identifying the most vulnerable areas that require immediate conservation intervention. Parallel mineralogical and petrographic studies show that the Samaipata rock is a quartz-rich, porous, well-sorted sandstone, classified as quartz arenite or subarcosic arenite. The cement of the rock is composed of quartz overgrowth and ubiquitous, pore-filling hematite-clay aggregates containing non-expanding kaolinite, illite, and expanding smectite. The rock exhibits different stages of weathering, from relatively fresh to strongly altered and heavily cracked. In comparison to fresh rock, the latter has cement enriched in clay minerals and is depleted in hematite due to weathering and the dissolution of the iron-bearing phase.
El Fuerte de Samaipata to wpisane na Listę Światowego Dziedzictwa UNESCO prehiszpańskie stanowisko archeologiczne w Boliwii. Jego główna część to skała ze złożonym układem tarasów, platform, zbiorników wodnych, kanałów i petroglifów. Szybko postępująca erozja sprawia, że petroglify stają się coraz mniej wyraźne, a niektóre nie są już rozpoznawalne. Głównym tematem badań jest wskazanie wszystkich czynników ryzyka sprzyjających erozji oraz stworzenie map ryzyka identyfikujących najbardziej wrażliwe obszary wymagające natychmiastowej interwencji konserwatorskiej. Badania mineralogiczne i petrograficzne wskazują, że Samaipata to bogaty w kwarc, porowaty, dobrze posortowany piaskowiec, sklasyfikowany jako arenit kwarcowy lub arenit subarkozowy. Spoiwo składa się z przerostu kwarcu i wszechobecnych, wypełniających pory agregatów hematytowo-gliniastych zawierających nierozprężający się kaolinit, illit i rozszerzający się smektyt. Skała wykazuje różne etapy wietrzenia, od stosunkowo świeżego do mocno zmienionego i mocno spękanego. W porównaniu ze świeżą skałą ta ostatnia ma cement wzbogacony w minerały ilaste i jest zubożona w hematyt z powodu wietrzenia i rozpuszczenia fazy żelazonośnej.

Opis:
Actual status of mountain forests especialy, of Norway spruce (Picea abies Karst. (L)) stands is a result of combined action between forest management measures and biotic and abiotic risk factors. In this context, tree growth dynamics is a result of multifactor interaction (competition, disturbance, management practice, climate etc.). Wind damage affect the stand structure and normal ecosystem functions including the relationship between individual tree growth and competition processes. Though, it is recorded a diminishing of productive capacity for affected stands as well as a significant diameter increment for remaining standing trees. The correlation between tree growth (cumulate basal area increment in the last 10 years) and competition (Hegyi and Schutz competition indices) was analysed in stands with different windfall intensity. No relationship between tree growth and competition was observed in highly affected stands. Schutz competition index explains better individual tree growth comparing with Hegyi index in low or no-affected stand by windthrow. The variability of the basal area increment (lnΔɡ10), explained by competition indices, is rather low (<2%) in the stand that had been highly affected by windfall, regardless of the selected competition index. Thus, significant reduction of the stand density related to number of trees (low density), as a consequence of high intensity windfalls, crown competition has a very small influence on the basal area increment comparing with situations met in low (high density) and moderate (medium density) affected stands.

The aim of this study was to evaluate the relationship between UA and cardiovascular risk factors, anthropometric parameters and body composition in patients with AH. Materials and method. In 138 patients with AH the following parameters were evaluated: UA, low and high density lipoproteins (LDL-C, HDL-C), triglycerides (TG), fasting glucose (FG), creatinine; body mass index (BMI), waist circumference (WC), fat mass (FM), fat free mass (FFM) and total body water (TBW). Results. Positive correlations were shown between UA and LDL-C (p=0.041), TG (p<0.001), FG (p=0.025) and creatinine (p<0.001) and negative between UA and HDL-C (p<0.001). Significant associations between UA and anthropometric parameters and body components, such as WC (p<0.001), BMI (p<0.001), FFM (p<0.001) and TBW (p<0.001), were also observed. In the multiple regression model, independent predictors of UA concentration were serum creatinine and TBW (R2=0.45; p<0.001). Conclusions. In patients with AH, uric acid was significantly related to cardiovascular risk factors, including obesity. However, the main anthropometric determinant of plasma UA concentration is FFM. The consideration of body composition in the interpretation of UA concentration appears to be justified, but the verification of this hypothesis requires further studies.

Introduction and objective. Hepatitis A Virus (HAV), reportedly the most common cause of acute viral hepatitis in developing countries, infects millions of people worldwide each year. The aim of the study is to investigate the seropositivity of anti-hepatitis A virus (HAV) IgG and IgM in all age groups in Erzurum, and to determine the effect of various factors such as age, gender, climatic conditions and HAV vaccination (included in 2012 in the National Immunization Schedule on seroprevalence) on the seropositivity. Materials and method. The serological results of 25,007 individuals referred to Erzurum Public Health Microbiology Laboratory between January 2015 – December 2018 were retrospectively reviewed to test for the presence of anti-HAV IgG and IgM. The patient ages were 0–93 years. Serum samples were analyzed by ELISA. S/CO values of ≥1.00 and >1.21 were considered positive for anti-HAV IgG and IgM, respectively; results below this value were considered negative. Results. Anti-HAV IgG and IgM seropositivities were 87.3% and 0.2%, respectively. Anti-HAV IgG prevalence – 88.5% and 86.4%, anti-HAV IgM positivity – 0.1% and 0.3% in men and women. Anti-HAV IgG seroprevalence – 87%, 73.2%, 58.7%, 75.2%, 86.1%, 89.8%, 96.1%, 99.1%, 99.1% and 99.3%, respectively, at 0–4, 5–9 10–14, 15–19, 20–24, 25–29, 30–39, 40–49, 50–59 and >60 age groups. Anti-HAV IgM seropositivity – 0, 0.1%, 0.7%, 0.7%, 0.3%, 0, 0.1%, 0.2%, 0.1%, and 0.2%, respectively, in the same age groups. Anti-HAV IgM positivity was the highest in November – 36(0.97%. Conclusion. In Erzurum, anti-HAV IgG prevalence is tremendously high, whereas prevalence of anti-HAV IgM is exceptionally low, especially in the paediatric age group. Therefore, HAV vaccine is provided free of charge in Turkey, including Erzurum, since 2012.

Social anxiety is one of the most common mental disorders. Studies show that 7-13 % of general population in Western countries suffers from this ailment. It may coexist with depression, general anxiety disorder, panic disorder and more. Moreover, social anxiety can cause eating disorders and a large percentage of social anxiety disorder patients were reported to abuse alcohol and drugs. On the other hand, social fears are also common amongst the general population. Approximately 40% of people find it difficult to talk to strangers, give public speeches or participate in various meetings or any other social situation. Specific form of social anxiety, interesting due to constant examination in educational system, is a problem which has been called test anxiety or examination stress. Evidence suggest that this condition may be responsible for some variation in subjective well-being. This article analyses the prevalence, risk factors, disease impact and treatment of social anxiety from the perspective of its meaning within educational context.

Introduction and objective. Hungary is one of the areas in Europe most infected with ragweed (Ambrosia artemisiifolia L.) and its pollen, and is the most important cause of seasonal allergic rhinoconjunctivitis in the country. The aim of the study was to investigate the association between ragweed pollen allergy and long-term ragweed pollen load, as well as analysis of the the impacts of additional potential risk factors on health outcomes. Materials and method. A modified version of standardized questionnaires, based on the International Study of Asthma and Allergy in Childhood, were completed by the parents of schoolchildren aged 8 – 9 attending 3rd grade classes throughout the country. Pollen load was calculated for each settlement from daily ragweed pollen concentrations monitored by 19 monitoring stations in the country. Descriptive and analytical statistical methods were applied. Results. At national level there was a significant inverse association between prevalence of ragweed allergy and its pollen load, but significance was lost after excluding data from Budapest, the capital city, due to the impact of urbanization. In the adjusted model, parental atopic disease was the strongest risk factor (either parent had atopic disease aOR=2.60; 95% CI=2.31–2.93 or both parents had atopic disease aOR=4.56; 95% CI=3.71–5.60). Further significant risk factors were male gender (aOR=1.52; 95% CI=1.36–1.71), lower respiratory infection in the first two years of life (aOR=1.91; 95% CI=1.70–2.16), and unshared children’s room (aOR=1.22; 95% CI=1.09–1.37). Allergy was significantly less common among children whose parents received social aid (aOR=0.83; 95% CI=0.72–0.97) and whose mother smoked during pregnancy (aOR=0.80; 95% CI=0.64–0.99). Conclusions. Higher ragweed pollen exposure was not found to be associated with higher risk of ragweed allergy.

Opis:
Objectives: The aim of this study was to assess the exposure of patients to organic substances produced and identified in surgical smoke formed in the abdominal cavity during laparoscopic cholecystectomy. Material and Methods: Identification of these substances in surgical smoke was performed by the use of gas chromatography-mass spectrometry (GC-MS) with selective ion monitoring (SIM). The selected biomarkers of exposure to surgical smoke included benzene, toluene, ethylbenzene and xylene. Their concentrations in the urine samples collected from each patient before and after the surgery were determined by SPME-GC/MS. Results: Qualitative analysis of the smoke produced during laparoscopic procedures revealed the presence of a wide variety of potentially toxic chemicals such as benzene, toluene, xylene, dioxins and other substances. The average concentrations of benzene and toluene in the urine of the patients who underwent laparoscopic cholecystectomy, in contrast to the other determined compounds, were significantly higher after the surgery than before it, which indicates that they were absorbed. Conclusions: The source of the compounds produced in the abdominal cavity during the surgery is tissue pyrolysis in the presence of carbon dioxide atmosphere. All patients undergoing laparoscopic procedures are at risk of absorbing and excreting smoke by-products. Exposure of the patient to emerging chemical compounds is usually a one-time and short-term incident, yet concentrations of benzene and toluene found in the urine were significantly higher after the surgery than before it.

Objectives Defined as attending work while ill, presenteeism is highly prevalent and has negative consequences such as reduced productivity and lower well-being for workers. This study aims to estimate the prevalence of presenteeism among Korean workers during the COVID-19 pandemic and identify the risk factors. Material and Methods Using data extracted from the second wave of the Korea Health Panel Survey in 2019–2021, this study assessed experience of presenteeism and the number of presenteeism days as the dependent variable. Independent variables included gender, age group, educational level, employment status, household income quartile, and the presence of chronic conditions. Two generalized estimating equation models were used. Results In 2019, 30.6% of participants reported experiencing presenteeism; this decreased to 17.9% in 2020 and 13.5% in 2021. The mean number of presenteeism days decreased from 2.30 days in 2019 to 1.46 days in 2020 and to 1.04 days in 2021. The participants were less likely to experience presenteeism in 2020 and 2021 than in 2019 (OR = 0.48 and OR = 0.36, respectively, p < 0.001). The risk of presenteeism is higher among women, younger age groups, participants with regular employment or on-contract positions, lower income, and chronic conditions than their counterparts. The number of presenteeism days significantly decreased in 2020 and 2021 (β = –0.44 and –0.78, respectively, p < 0.001). Conclusions Workers were less likely to experience presenteeism in 2020 and 2021 than in 2019, and the number of presenteeism days decreased during the COVID-19 pandemic. The risk of presenteeism was associated with worker characteristics.

Opis:
Background and Objectives: Over-the-counter availability and a good safety profile make paracetamol one of the most common analgesics in developed countries but also the leading cause of liver failure due to overdose. The objectives of the study were to identify modifiable risk factors for severe hepatotoxicity following paracetamol overdose in adults. Materials and Methods: A retrospective cohort study involved the consecutive adult patients hospitalized in a toxicological center over a period of seven years due to paracetamol overdose. Complete medical datasets of laboratory and anamnestic variables were analyzed and validated by means of logistic regression model. Results: A total of 185 patients entered the study, including 25 individuals who developed severe hepatotoxicity (plasma aminotransferases levels above 1000 UI/L) and 31 individuals with mild to moderate liver injury (plasma aminotransferases levels above upper normal range, but below 1000 UI/L). In the univariable analysis, significant hepatotoxicity risk factors were male gender, alcohol abuse, an ingested paracetamol dose, and a timespan from ingestion to hospital admission. The later one was the only significant risk factor in the multivariable model (adjusted odds ratio 1.08; 95% CI: 1.03–1.12). Conclusions: A delay in hospital admission, resulting in a delayed administration of disease-specific treatment outweighs any other known risk factors of paracetamol-induced hepatotoxicity.

Opis:
This paper demonstrates how the Sharpe Ratio can be modified by altering the measure of “total risk” in the denominator of the Sharpe Ratio (i.e., the standard deviation) to include liquidity risk, a major risk for investors in hedge funds that is missing from the standard Sharpe Ratio formulation. We refer to our liquidity-risk-adjusted performance ratio as the LRAPR. The results of our analysis of 1186 hedge funds alive in 2012–2020 show that funds with higher liquidity risk exhibit higher Sharpe Ratios and higher Alphas (as estimated in a 7-factor model that does not incorporate liquidity risk). We posit that analysts and investors should not necessarily take these higher Sharpe Ratios and higher Alphas as indications of fund superiority; what appears to be superior manager skill may rather be a compensation for bearing liquidity risk. Our LRAPR is a tool that analysts or investors could use to compare funds on a more equal footing, adjusting for differential liquidity risk across funds.

The objective of the study was to describe the characteristics of agriculture and forestry related injury cases admitted to an Emergency Department (ED), and to asses factors related to injury severity and hospital admission. Retrospective analysis of ED case records in Teaching Hospital No 1 in Lublin, from January 2004 to December 2005 were utilized. Inclusion criteria: patient >14 years old, with agriculture and forestry related injuries. Univariate and bivariate descriptive analyses and multiple logistic regressions were performed. 3791 cases were included, 63.1% males, 53.3% cases younger than 30 years and 47.1% of the patients sustained injuries related to machines or falls. After adjusting for age, sex and the presence of multiple injuries, animal related injuries, followed by machine related injuries and falls, were at higher risk of a more severe injury (OR: 1.77, 1.61 and 1.50, respectively). This groups also showed a higher likelihood of hospital admission (OR: 2.03, 192 and 2.00, respectively). Patients attended to in the ED during night hours (OR: 2.06) were also at a higher risk of hospitalization. It was concluded that animal related injuries, agriculture machine operators, and falls, besides accounting for two thirds of analyzed cases, are the mechanism of injury with a greater risk of a more severe injury and higher likelihood of a hospitalization.

Opis:
Epidemiological studies on caseous lymphadenitis were carried out in Poland in 1996 and 2002 among goat herds covered by a milk recording program. Between-herd seroprevalence was 13.2% in 1996 and increased to 62.5% in 2002. The average size of seropositive herds was statistically significantly higher than that of seronegative ones, however there was no statistically significant difference in the age between the herds. A statistically significant prevalence ratio (PR) was identified and relevant attributable risk for exposed animals (ARexp) was calculated for the following risk factors: presence of seropositive males in a herd (PR=8.350; ARexp=0.651), presence of superficial abscesses in animals (PR=6.142; ARexp=0.620), presence of respiratory signs (PR=2.900; ARexp=0.393), presence of animals in poor condition in a herd (PR=2.774; ARexp=0.390) and occurrence of reproductive failures in a herd (PR=1.798; ARexp=0.230). Purchase of animals from abroad, mastitis and husbandry conditions (housing system, grazing system, hygienic conditions) were not shown to be statistically significant risk factors.

Opis:
Hazard jest obecnie popularną i legalną formą aktywności podejmowaną przez ludzi na całym świecie. Wprowadzone w ostatnim okresie zmiany prawne dotyczące gier losowych, większa ich dostępność z racji rozpowszechnienia salonów gier sprawiły, że coraz częstsze są przypadki uzależnienia od hazardu. W tej sytuacji istnieje potrzeba lepszego poznania, czym jest hazard patologiczny. Prezentowany artykuł jest poświęcony tej tematyce. W literaturze przedmiotu najczęściej traktuje się jako synonimiczne takie określenia, jak hazard kompulsywny, hazard patologiczny, hazard problematyczny. Hazard patologiczny jest zjawiskiem złożonym. Definiując hazard, tradycyjnie zwraca się raczej uwagę na skutki ekonomiczne i społeczne, a nic na proces czy też naturę zjawiska. Klinicyści natomiast koncentrują się na negatywnych następstwach aktywności hazardowej, proponują typologie i opracowują definicje, które mogą być przydatne do bardziej adekwatnej operacjonalizacji tego konstruktu, jakim jest hazard. Krytyczna analiza literatury przedmiotu pozwoliła na wyodrębnienie czynników, które mogą warunkować rozwój patologicznego hazardu. Są to czynniki: rodzinne/genetyczne, socjodemograficzne (np. wiek, płeć, pochodzenie etniczne, rodzaj gry losowej), podmiotowe (np. osobowość, reakcje biochemiczne, procesy poznawcze, stany psychiczne) oraz religijne/duchowe.
Gambling is now a popular lawful activity among people around the world. Due to recent changes of legal regulations concerning gambling, access to gambling has become more widespread and, as a result, an increase in the prevalence of pathological gambling has been noted. Therefore, an urgent need for better understanding of the phenomenon of pathological gambling among health-care specialists becomes evident. In this field, such concepts as compulsive, pathological or problem gambling are often treated synonymously. Pathological gambling is a complex phenomenon. Traditionally, the definitions of gambling have been constructed basing on the assumptions of economic or social repercussions rather than taking into account the process or phenomenon of gambling itself. However, clinicians focusing on negative consequences of the gambling behavior, developed typologies and worked out the definitions that may prove beneficial for more adequate operationalizing this concept. A critical review of the literature showed that familial /genetic, sociological /demographics (e.g. age, gender, ethnicity, forms of gambling), individual (e.g. an individual’s personality, biochemistry, cognitions, and psychological states) and religion/ spirituality factors may be implicated in the development and maintenance of pathological gambling.

Opis:
Many-year studies on aerosols as an infection vector, despite their wide range, ignored dental aerosol. All procedures performed with the use of dental unit handpieces cause the formation of aerosol and splatter which are commonly contaminated with bacteria, viruses, fungi, often also with blood. Aerosols are liquid and solid particles, 50 μm or less in diameter, suspended in air. Splatter is usually described as a mixture of air, water and/or solid substances; water droplets in splatter are from 50 μm to several millimetres in diameter and are visible to the naked eye. The most intensive aerosol and splatter emission occurs during the work of an ultrasonic scaler tip and a bur on a high-speed handpiece. Air-water aerosol produced during dental treatment procedures emerges from a patient’s mouth and mixes with the surrounding air, thus infl uencing its composition. Because air contained in this space is the air breathed by both dentist and patient, its composition is extremely important as a potential threat to the dentist’s health. According to the author, insuffi cient awareness of health risk, working habits, and economic factors are the reasons why dentists do not apply the available and recommended methods of protection against the infl uence of bioaerosol and splatter. Behaviour protecting a dentist and an assistant from the threat resulting from the infl uence of dental aerosol cannot be limited to solated actions. The author, on the basis of the literature and own research, characterizes bioaerosol and splatter in a dental surgery and reviews a full range of protective measures against these risk factors.

Objectives To study any possible correlation between arsenic toxicity and the development of oral carcinoma in West Bengal population. Material and Methods Ethical clearance for this study was obtained from the Vivekananda Institute of Medical Sciences. Out of 30 785 patients attending our hospital from November 2012 to July 2015, 107 cases and 50 control individuals were selected. The hair and buccal smear samples were obtained upon their consent for the purpose of the analysis of arsenic count and cytogenetic damage, respectively. Results Ninety-six percent of cases came from the highly arsenic affected districts and 81.3% showed their arsenic count above the safe limit (0.8 μg/g) whereas 96% of the controls’ arsenic count was within the safe limit. The study showed a significant difference of the micronuclei and apoptosis frequency between the cases and controls. Conclusions The difference of micronuclei and apoptosis frequency between cases and controls was significant. The maximum number of cases came from highly arsenic affected areas and a higher percentage of cases showed elevated arsenic count, as compared to controls, which may indicate a possible link between arsenic toxicity and this disease. However, a larger sample size is required for a proper correlation. Int J Occup Med Environ Health 2017;30(2):271–279

Objectives: Only a few studies have analyzed the health of self-employed workers. This cross-sectional study is the first to compare health status among craftsmen joiners and paid joiners. Material and Methods: Clinical and paraclinical data for self-employed craftsmen and employees were collected by occupational health doctors according to a standardized protocol and compared. Health data and professional status relationships were analyzed by logistic regression. Results: A total of 171 craftsmen and 196 paid workers were included. Craftsmen had more dermatologic pathologies (odds ratio (OR) = 2.67, p < 0.05), ear/nose/throat symptoms (OR = 3.38, p < 0.001), pulmonary symptoms (OR = 2.46, p < 0.05), musculoskeletal symptoms (OR = 3.09, p < 0.001), and abnormal audiogram (OR = 3.50, p < 0.001). The FEV₁ was significantly lower among craftsmen (p < 0.01), independently of tobacco smoke exposure. Conclusions: This survey highlights a high morbidity rate among self-employed craftsmen, suggesting that among woodworkers, professional status can be a risk factor for health. The preventive medical system for craftsmen has to be rethought to guarantee better safety for this population.

Opis:
Hyperuricemia accompanies many pathologies that contribute to overall death rate. The population-based multifaceted study of older adults in Poland made it possible to assess the effect of serum uric acid (SUA) on overall mortality. The PolSenior study performed between 2007–2011 included 3926 participants aged 65 years or above (mean age 79 ± 9 years) not treated with xanthin oxidase inhibitors (XOI) who were stratified by sex and SUA concentration into six subgroups increasing by 1 mg/dL. In 2019, survival data were retrieved from the population register. The crude risk of death was significantly higher in men and women with SUA ≥ 7 mg/dL. After adjustment to statistically significant factors, SUA remained a risk factor of death in men with SUA ≥ 8 mg/dL only, potentially due to the limited number of women with high SUA levels. Furthermore, age, heart failure, diabetes, and activities of daily living ≤ 4 pts were identified as factors increasing mortality risk regardless of sex. The risk of death increased also with smoking, past stroke, COPD/asthma, and hs-CRP > 3 mg/dL for men; and eGFR < 45 mL/min/1.73 m2, mini nutritional assessment ≤ 7 pts, and loop diuretics use for women. Mild hyperuricemia is a significant health status marker and an independent risk factor for overall mortality in older Caucasians not receiving XOI. Increased mortality is mostly limited to subjects with SUA levels ≥ 8 mg/dL.

Zhang, Yifan
Opis:
Nowadays internationalization as a trend attracts more and more companies join to this stream. While the companies expand their overseas market, uncertainties from foreign market and different type of risk in a new country or region become a barrier that those companies need to surmount, thus to identify the risk factors and analysis them would help companies avoid needless failure experienced by others, meanwhile risk management also lead companies step on the right internationalization path.This study aim to understand the reason why companies go abroad, and point out different stages of internationalization. Associate with uncertainties and risks in the foreign market, this study identified the risk factors and constructed a framework of risk management, sought to assess, monitor, and mitigate identified risks.Then according to findings derived from quantitative and qualitative analysis, significance test in the case study will evaluate all the classified risk factors experienced by firms and provide the use of risk models, enabling them to readjust internationalization strategy in the foreign markets. In addition to the provision of approved models and entry strategies, findings from this study also could be adopted by policymakers and risk assessments, to help enterprises plan and conduct their business in the concerned foreign markets.

Opis:
Depression is a common psychiatric complication of apoplectic stroke. It is suggested that even 80% of patients who experienced stroke may suffer from intensive depressive symptoms. Also, it is estimated that symptomatic depressive episode develops among 1/3 of patients. Research reveals that post – stroke depression has a significant impact on rehabilitation, quality of life and everyday activity of each patient who have suffered from apoplectic stroke indeed. Undoubtedly, indication and specification of fundamental predictors of post-stroke depression provides early treatment and quick and more effective assistance. Until now a coherent model of risk factors has not been formed. Research carried out on predicators resulted in contradictory data referring both to importance of particular factors and their relation to depressive disorder. The main aim of the following research is to specify significant risk factors which have an impact on post- stroke depression symptoms. Furthermore, an addition hypothesis has been raised. The following claim assumes that there is a strict relation between intensive depressive symptoms and worse cognitive functioning both in the phase of acute stroke and the period of 3 to 6 month after the stroke appeared. In addition, in order to capture the course of disorder, a hypothesis concerning differences between intensification of depressive symptoms and level of cognitive efficiency in the period of 10 days after the stroke and after 3 to 6 months after the vascular incident has been made. In order to verify the made hypotheses, a research was carried out among patients, hospitalized in Ludwik Rydygier’s Hospital in Cracow and in the University Hospital in Cracow, who suffered from inschemian brain stroke. The patients were examined twice: 10 month after the stroke and then in the period of 3 to 6 months after the disorder. 37 people were included in the first examination, while the latter – 21 patients. A detailed psychological history introduced the general data about the patient. Also, part of the information was taken from the disease card. Results of the neurologic research gave knowledge about the stroke’s localization and the exact number of ischemia centers. The cognitive efficiency has been assessed by MMSE, while the intensification of depressive symptoms is specified by the psychopathological scale of HDRS and two scales of self – assessment (BDI; DISCs).Results of the examination has indicated that smoking has a factor contributes to depressive symptoms in acute stroke phase. The data analysis results in the claim that smoking increases symptoms of depression up to 17% in the period of 10 days after the stroke has occurred. Additionally, it is claimed that occurrence of depressive symptoms in 3 to 6 months after the stroke is connected with the earlier stroke indeed. Simile of intensification of depressive symptoms to level of cognitive efficiency proves that patients with symptoms of depression, which has revealed between 3 and 6 months after the disorder (in comparison to patients who do not reveal that kind of symptoms), specifies weaker cognitive functioning in the acute phase of stroke. It proves that the lower level of cognitive efficiency shortly after the apoplectic stroke may be the predicator of subsequent intensification of depression in case of post – stroke patients.Another goal of the research was to show each change in the extend of intensification of depressive symptoms revealed by patients who have just suffered from the apoplectic stroke and then in the period of between 3 and 6 months after the disorder. The analysis of the research outcome shown the increase of depressive symptoms in respect of HDRS scale. Additionally, it was possible to specify the dynamics of changes in case of cognitive functioning distinctive for patients who are 10 days after the stroke and then between 3 to 6 month after the disorder. The analysis of the provided outcome shown improved
Depresja stanowi najczęstsze psychiatryczne powikłanie udaru mózgu. Sugeruje się, że nawet 80% pacjentów po udarze mózgu może cierpieć na skutek nasilonych objawów depresyjnych, a u ok. 1/3 chorych rozwija się pełnoobjawowy epizod depresyjny. Wyniki badań świadczą, iż pojawienie się depresji poudarowej ma niebagatelny wpływ na rehabilitację, jakość życia i codzienną aktywność osób po udarze mózgu. Niewątpliwie, znalezienie i wyszczególnienie istotnych predyktorów depresji poudarowej umożliwiłoby wczesne włączenie leczenia oraz szybkie i bardziej skuteczne dostarczenie pomocy. Dotychczas nie utworzono spójnego modelu czynników ryzyka depresji po udarze mózgu. W wyniku przeprowadzonych badań uzyskano wiele sprzecznych danych, zarówno w zakresie istotności poszczególnych czynników, jak i kierunku ich związku ze zmianą prawdopodobieństwa pojawienia się zaburzeń depresyjnych. Głównym celem podjętych badań była próba wyodrębnienia istotnych predyktorów nasilenia objawów depresyjnych po udarze mózgu. Wysunięto przy tym dodatkową hipotezę zakładającą istnienie związku między nasilonymi objawami depresyjnymi a gorszym funkcjonowaniem poznawczym, zarówno w fazie ostrej udaru, jak i w 3-6 miesięcy później. Dodatkowo - w celu uchwycenia dynamiki przebiegu zaburzeń – wysunięto hipotezy dotyczące istnienia różnicy w zakresie nasilenia objawów depresyjnych i poziomu sprawności poznawczej w okresie do 10 dni od udaru mózgu i po upływie 3-6 miesięcy od wystąpienia incydentu naczyniowego. W celu zweryfikowania postawionych hipotez przeprowadzono badanie wśród chorych po niedokrwiennym udarze mózgu, hospitalizowanych na Oddziale Neurologii i Udarów Mózgu z Pododdziałem Udarów Mózgu Szpitala Specjalistycznego im. Ludwika Rydygiera w Krakowie oraz na Oddziale Klinicznym Kliniki Neurologii Szpitala Uniwersyteckiego w Krakowie. Chorzy zostali zbadani dwukrotnie: w okresie do 10 dni od udaru mózgu oraz w 3-6 miesięcy później. Do badania I zostały włączone wyniki 37 osób, w badaniu II uczestniczyło 21 chorych. Dane ogólne dotyczące pacjenta uzyskiwano przeprowadzając wywiad psychologiczny. Część informacji pochodziła również z karty choroby badanego. Wyniki przeprowadzonych badań neuroobrazowych dostarczały wiedzy na temat lokalizacji udaru oraz ilości ognisk niedokrwiennych. Sprawność poznawcza została oceniona przy pomocy MMSE, natomiast nasilenie objawów depresyjnych obserwacyjną skalą psychopatologiczną (HDRS) oraz dwoma skalami samooceny (BDI; DISCs). Wyniki przeprowadzonego badania wskazały palenie tytoniu jako czynnik sprzyjający wystąpieniu objawów depresyjnych w ostrej fazie udaru mózgu. Z analizy zebranych danych wynika, że fakt palenia papierosów może nawet w 17% odpowiadać za nasilenie symptomów depresji przejawianych w okresie do 10 dni od incydentu naczyniowego. Ustalono również, iż kolejny udar mózgu wiąże się z większym prawdopodobieństwem wystąpienia objawów depresyjnych w fazie średnioterminowej. W trakcie porównywania nasilenia objawów depresyjnych i poziomu sprawności poznawczej wykazano, iż osoby z objawami depresyjnymi ujawnianymi w okresie 3-6 miesięcy od wystąpienia incydentu naczyniowego – w porównaniu do osób, które takich objawów nie wykazują – funkcjonują znacznie gorzej poznawczo w ostrej fazie udaru. Oznacza to, iż niższy poziom sprawności poznawczej krótko po udarze mózgu może być predyktorem późniejszej, nasilonej depresyjności u pacjentów poudarowych. Kolejnym celem badania było ukazanie zmian w zakresie nasilenie objawów depresji przejawianych przez osoby krótko po udarze, a następnie po upływie 3-6 miesięcy. Analiza wyników wykazała wzrost symptomów depresyjnych w czasie w odniesieniu do obserwacyjnej skali HDRS. Dodatkowo udało się przedstawić dynamikę zmian w zakresie sprawności funkcjonowania poznawczego charakteryzującego chorych w okresie do 10 dni od udaru mózgu i w 3-6 miesięcy później. Analiza wyników wykazała poprawę funkcjonowania poznawczego w czasie.

Opis:
ObjectivesEpidemiological studies show that apical periodontitis (AP), alongside tooth decay, is the most common oral disease. The aim of the study was to evaluate the influence of smoking on the prevalence of AP in the population of the Łódź region, Poland.Material and MethodsThe study involved 815 first-time, randomly selected patients reporting to the Central Teaching Hospital of the Medical University of Lodz. The studied group was a systematic sample of the population admitted for treatment in 2016. The study consisted of a questionnaire and a radiological part. Each patient filled out a questionnaire containing demographic data, and an interview regarding smoking and diabetes. The radiological part of the study included the analysis of panoramic radiographs which showed the periapical status, and the presence and quality of root canal treatment.ResultsTeeth with AP were observed more frequently in patients addicted to tobacco either at the time of the study or in the past (group 1) – 7.2% than in people who had never smoked (group 2) – 5.2% (p < 0.0005). In the teeth without root canal treatment, AP was observed more frequently in group 1 – 3.5% than in group 2 – 1.9% (p < 0.0005). A statistically significant difference was found in the percentage of endodontically treated teeth between group 1 and group 2 (10.7% vs. 9.6%) (p = 0.017). However, no difference was observed in the frequency of AP in the endodontically treated teeth in both groups (37.6% vs. 35.8%) (p = 0.451).ConclusionsSmokers are a group facing an increased risk of AP and, therefore, there is a need for an early detection and treatment of caries and its complications in this group of patients. The multifactorial etiology of AP indicates the necessity to undertake further studies on the effect of smoking on the periapical status.

Opis:
Coastal areas in Anantigha are utilized as dumpsite for industrial and domestic wastes including effluent from local industries and inhabitants of the area despite their usage for crop cultivation. Thus, the present study was designed to assess the concentration, pollution load and ecological risk of heavy metal in Anantigha coastal area. Standard pollution indices such as contamination factor (Cf), degree of contamination, pollution load index (PLI), enrichment factor (EF), geo-accumulation index (Igeo) and ecological risk index were deployed to assess the level of heavy metals contamination in the area. The results showed that the sediment was acidic under dried conditions and low in conductivity. The mean concentration levels of all the heavy metals were lower than their mean background values except for Al. The orders of dominance for concentration of heavy metals were: Al>Fe>Mn>Cu>Zn (Station 1) and Al>Fe>Mn>Zn>Cu (Stations 2, 3 and 4). Analyzed data showed that the sediments in the area are contaminated with Al with Igeo result showing station 2 and 4 been moderately to heavily contaminated with Al while station 4 was heavily contaminated with aluminium. Station 1 had low degree of contamination, whereas station 2 and 4 had moderate degree of contamination, and station 3 showed considerable degree of contamination. The PLI result indicates unpolluted condition and the area were not enriched by the studied heavy metals as shown by EF values. Hence, the sediment in Anantigha coastal marine area was classified as having low ecological risk factor. However, the levels of these metals are not static; there is tendency for increase as a result of increased human input and activities. Hence, there is a need for regular soil testing.

Opis:
In today’s technology-driven world-economy, banking-services have been modernized where customers compete for comparative time-saving-options. Bangladesh, a developing country, is no exception. Besides traditional banking, Agent-banking, bKash, Western-Union etc. serve new-way financial-services. But, in 21st-Century business-mentality era, many factors are unpredictable. Strict laws & application can marginalize the magnitudes of Perceived-risk where developed countries are ahead of developing countries. But it does not guarantee risk-free digital-transaction where developing countries are vulnerable. It might have led a slower growth of digital-banking in countries like Bangladesh. Dealing with determinant Perceived-risk, current author proposed Voluntary-Insurance policy (Rahman, 2018) that deserves to be scrutinized. Using Factor Analysis and Hypothesis Testing on customers’ opinions helps identifying factors that have undermined the growth-trend of bank-led digital. Attributes “Phone call confirmation” has influenced customer’s preference using bKash. “No transaction fee” has influenced using bank-led digital. Addressing risk-factors, Voluntary-Insurance in place can ensure secured digital-banking that can enhance growth of usages digital-banking.
