The Hypothalamic-Pituitary-Gonadal Axis in Men with Schizophrenia.

Schizophrenia is a severe mental disorder with a chronic, progressive course. The etiology of this condition is linked to the interactions of multiple genes and environmental factors. The earlier age of onset of schizophrenia, the higher frequency of negative symptoms in the clinical presentation, and the poorer response to antipsychotic treatment in men compared to women suggests the involvement of sex hormones in these processes. This article aims to draw attention to the possible relationship between testosterone and some clinical features in male schizophrenic patients and discuss the complex nature of these phenomena based on data from the literature. PubMed, Web of Science, and Google Scholar databases were searched to select the papers without limiting the time of the publications. Hormone levels in the body are regulated by many organs and systems, and take place through the neuroendocrine, hormonal, neural, and metabolic pathways. Sex hormones play an important role in the development and function of the organism. Besides their impact on secondary sex characteristics, they influence brain development and function, mood, and cognition. In men with schizophrenia, altered testosterone levels were noted. In many cases, evidence from available single studies gave contradictory results. However, it seems that the testosterone level in men affected by schizophrenia may differ depending on the phase of the disease, types of clinical symptoms, and administered therapy. The etiology of testosterone level disturbances may be very complex. Besides the impact of the illness (schizophrenia), stress, and antipsychotic drug-induced hyperprolactinemia, testosterone levels may be influenced by, i.a., obesity, substances of abuse (e.g., ethanol), or liver damage.

Sociodemographic characteristic of changes in smoking patterns in rural and urban population of PURE Poland study: findings from 6-year follow up.

BACKGROUND: Tobacco smoking is one of the most serious modern civilization threats. According to WHO identifying patterns of tobacco use is essential for implementing effective preventive policies. The aim of the paper was to assess changes in smoking patterns among the PURE study population over 6 years. METHODS: The study sample comprised of 1784 adult participants from PURE Poland study, who were assessed at baseline (2007-2010) and then at 6-year follow-up. Participants were classified into current smokers, ex-smokers and never smokers. Smoking patterns were analyzed according to sex, age/birth cohort, place of residence (urban vs rural setting), and education level. RESULTS: Overall, a significant decrease of 3.1% in current smokers was observed (from 20.0% in baseline to 16.9 at follow-up). However, 0.8% of never smokers and 6.2% of ex-smokers at baseline were classified as current smokers at 6-year follow-up. Despite overall decrease in percentage of current smokers in both rural and urban area, in fact significantly more ex-smokers from rural area became current smokers after 6 years. Living in the rural area was associated with nearly two-fold increase in current smoking, and almost two-fold decline in chances to quit smoking. The highest percentage of current smokers was observed in birth year cohort 1961-1979. CONCLUSION: Despite a small but significant decline in overall smoking rates, important differences in smoking and quitting patterns emerged between rural and urban areas, as well as sexes. A less favorable smoking patterns were observed among women, and rural populations, suggesting that these are important targets of future tobacco control interventions in Poland.

Sociodemographic and behavioral factors associated with controlled hypertension after 9 years of observation of a PURE Poland cohort study.

Introduction: Despite some improvement in awareness and treatment of hypertension, blood pressure control is still below expectations in Poland. The aim of the study was to analyze the secular trend of hypertension prevalence in the PURE Poland cohort study over 9 years of observation and to analyze factors associated with controlled HT. Methods: The study group consisted of 1,598 participants enrolled in a Prospective Urban and Rural Epidemiological Study (PURE), who participated both in baseline (2007-2010) and 9-year follow-up (2016-2019). Hypertension was ascertained on the basis of (1) self-reported hypertension previously diagnosed by the physician, (2) self-reported anti-hypertensive medication, and/or (3) an average of two blood pressure measurements ≥140 mmHg systolic BP and/or ≥90 mmHg diastolic BP. Results: The prevalence of hypertension increased from 69.4% at baseline to 85.9% at 9-year follow-up. The chance of HT was 8.6-fold higher in the oldest vs. the youngest age group [OR 8.55; CI 4.47-16.1]. Male sex increased the chance for hypertension over 3-fold [OR 3.23; CI 2.26-4.73]. Obesity, according to BMI, increased the chance of HT 8-fold [OR 8.01; CI 5.20-12.8] in comparison with normal body weight. Male sex decreased the chance of controlled HT after 9 years [OR 0.68; CI 0.50-0.92]. There was no statistically significant association between controlled HT and age or place of residence. Higher and secondary education increased the chance of controlled HT over 2-fold in comparison with primary education [OR 2.35; CI 1.27-4.34, OR 2.34; CI 1.33-4.11]. Obesity significantly decreased the chance of controlled HT after 9 years in comparison with normal body weight [OR 0.54; CI 0.35-0.83]. Conclusion: Factors significantly increasing the chance for controlled hypertension after 9 years were female sex, secondary and tertiary education, normal body weight, and avoiding alcohol drinking. Changes in lifestyle, with special emphasis on maintaining normal body weight, should be the basis of prevention and control of HT.

Elderly Patient Care: A New Reality of the SARS-CoV-2 Pandemic.

Poland is among the European countries currently facing the second wave of the SARS-CoV-2 pandemic. A lot of studies confirm the mortality rate of COVID-19 increases with age. Considering the particularly adverse outcomes of a SARS-CoV-2 infection, preventing infections should be the priority for public health professionals. One method for preventing SARS-CoV-2 infections among eldery people may involve implementing procedures for limiting the spread of the pathogen, and providing education to medical staff, so as to bridge any gaps in knowledge on virus spread and post-infection or post-exposure management. Three residential medical centers in Poland were selected for evaluation of existing medical procedures to identify any errors in the current procedures applied for the prevention of SARS-CoV-2 spread in the facility. The project involved 4 steps: (1) Audit of the existing medical procedures; (2) Knowledge evaluation for the staff (n=185) in the senior- and disabled care facilities, administration of a knowledge test developed by the authors to assess knowledge on SARS-CoV-2 prevention; (3) Training for medical staff; (4) Updates and implementation of procedures. The knowledge test conducted revealed a lack of knowledge of medical personnel about SARS-CoV-2. The deficiencies of the surveyed group varied depending on the place of employment. Almost half of the surveyed medical centers (center No. 1 (52%) vs. center No. 2 (44%) vs. center No. 3(59%)) believed that elderly people usually do not show symptoms of SARS-CoV-2 infection. In the facility No. 1, 70% of respondents did know that SARS-CoV-2 can be transmitted via the alimentary route compared to center No. 2 and No. 3 where knowledge about it showed only 28,9% and 24,8% responders, respectively. Also, in facility No. 1, the least among the studied group (67%) knew that people with comorbidities were at risk of covid-19 compared to respondents from facility No. 2 and 3, where, respectively, 100% and 93% had such knowledge. Only 33.3% of the staff of facility No. 1 knew how to deal with a patient who will present symptoms such as temp >38 degrees with coughing or dyspnea while in institution No. 2 and 3, this knowledge was slightly higher at 44% and 60% respectively. The audit of the existing hygiene procedures used to limit the risk of SARS-CoV-2 spread demonstrated a number of shortcomings. Employees at the residential medical care centers included in the study had gaps in knowledge on the spread of SARS-CoV-2. The training sessions implemented at the next stage improved knowledge on SARS-CoV-2 infections. Additionally, decisions were made to modify certain procedures and introduce new ones to better prevent the spread of SARS-CoV-2.

Obesity and Chosen Non-Communicable Diseases in PURE Poland Cohort Study.

INTRODUCTION: Obesity has been associated with a higher risk of morbidity, disability, and death. The objective of this study was to assess the prevalence of obesity and chosen non-communicable diseases (NCDs) in the PURE Poland cohort study. MATERIAL AND METHODS: The study covers a group of 2035 people (1281 women and 754 men), who live in urban and rural areas of Lower Silesian voivodeship. The baseline study was conducted between 2007-2010. The data on demographic status and history of diseases were collected using questionnaires. The anthropometric parameters, blood pressure, blood lipids, and glucose level were measured. RESULTS: Normal body weight was observed in 28.1% of participants, whereas overweight and obesity were observed in 40.1% and 31.1% of participants, respectively. Moreover, there was a significant difference in the body weight between genders. Prevalence of obesity was similar in men and women (31.0% and 31.1%, respectively). Obesity was more prevalent in rural vs. urban residents (38.5% and 26.0%, respectively). In a logistic regression analysis, the odds for obesity was two-fold higher in participants aged >64 years and rural inhabitants (OR 1.91; 95% CI 1.36-2.70; OR 1.79; 95% CI 1.48-2.16, respectively). Participants with obesity had 2.5-fold higher odds for diabetes and hypertension and two-fold higher odds for CHD in comparison with non-obese individuals (OR 2.74; 95% CI 2.01-3.73, OR 2.54; 95% CI 2.03-3.17, OR 1.88; 95% CI 1.26-2.80, respectively). CONCLUSIONS: Taken together, the prevalence of obesity was associated with particular socio-demographic factors (age, place of residence, and level of education) as well as diabetes, hypertension, and coronary heart disease.
