Assessment of physicians' career satisfaction in the Silesian Voivodeship, Poland.

OBJECTIVE: Aim: To assess the career satisfaction of physician's in the Silesian Voivodeship, Poland, in relation to selected factors. PATIENTS AND METHODS: Materials and Methods: The questionnaire survey was conducted among 701 physicians and dentists from the Silesian Voivodeship, Poland, in the period from January to December 2018, using the PAPI (Paper and Pencil Interview) method. Physicians' Career Satisfaction was measured and basic socio-demographic, economic and occupational data, concerning lifestyle and health, and also the level of life satisfaction according to the SWLS (Satisfaction with Life Scale) were collected. Moreover, the occurrence of anxiety and/or depressive symptoms according to the HADS (Hospital Anxiety and Depression Scale) were included in the analyses. RESULTS: Results: The career satisfaction of the surveyed Silesian physicians and dentists was moderate. Wages and combining personal life with work were rated the lowest, while interpersonal opportunities were rated the highest. The predictors: age, economic status and body mass index (BMI) were significant; in addition, in younger age group (25-49 years) - practicing sports and chronic fatigue, and in older age group (50-80 years) - the presence of a chronic disease. A moderate correlation between the level of career satisfaction and life satisfaction was revealed, as well as a lower score in people with the occurrence of anxiety and/or depression symptoms. CONCLUSION: Conclusions: The diversified level of career satisfaction of physicians in separated aspects makes it necessary to verify them both at the level of health care units and at higher levels.

Possibility of Using Surgical Pleth Index in Predicting Postoperative Pain in Patients after Vitrectomy Performed under General Anesthesia.

Adequacy of anesthesia concept (AoA) in the guidance of general anesthesia (GA) is based on entropy, and it also reflects the actual depth of anesthesia and the surgical pleth index (SPI). Therefore, this study aimed to analyze the potential existence of relationships between SPI values at certain stages of the AoA-guided GA for vitreoretinal surgeries (VRS) and the incidence of intolerable postoperative pain perception (IPPP). A total of 175 patients were each assigned to one of five groups. In the first, the VRS procedure was performed under GA without premedication; in the second group, patients received metamizole before GA; in the third, patients received acetaminophen before GA; in the fourth group, patients received Alcaine before GA; and, in the peribulbar block group, the patients received a peribulbar block with a mix of the solutions of lignocaine and bupivacaine. Between the patients declaring mild and statistically significant differences in the IPPP in terms of SPI values before induction (52.3 ± 18.8 vs. 63.9 ± 18.1, p < 0.05) and after emergence from GA (51.1 ± 13 vs. 68.1 ± 8.8; p < 0.001), it was observed that the patients postoperatively correlated with heart rate variations despite the group allocation. The current study proves the feasibility that preoperative SPI values help with predicting IPPP immediately after VRS under AoA guidance and discrimination (between mild diagnoses and IPPP when based on postoperative SPI values) as they correlate with heart rate variations. Specifically, this applies when the countermeasures of IPPP and hemodynamic fluctuations are understood to be of importance in reducing unwelcome adverse events.

Socioeconomic and Health Determinants of the Prevalence of COVID-19 in a Population of Children with Respiratory Diseases and Symptoms.

BACKGROUND: Most epidemiological studies indicate that bronchial asthma is not a risk factor for COVID-19, but previous analyses have not additionally focused on the socioeconomic determinants of SARS-CoV-2 infection in children with asthma, bronchitis, and respiratory symptoms. AIMS: This research aimed to investigate the correlation between the socioeconomic status of families and the prevalence of respiratory conditions such as asthma, bronchitis, and respiratory symptoms in children, in addition to exploring their association with the prevalence of COVID-19. The study involved a cross-sectional epidemiological investigation conducted in 2022, encompassing 2454 students from elementary schools in Poland. The parents of the students completed a questionnaire modeled after the International Study on Asthma and Allergies in Childhood (ISAAC). Socioeconomic status (SES) indicators were determined based on parental education, self-reported economic status, and housing conditions. To assess the impact of social factors and health on the occurrence of COVID-19, odds ratios (ORs) were calculated. The findings revealed several COVID-19 risk factors, including higher maternal (OR 2.2; 95%CI: 1.3-3.0) and paternal education (OR 1.9; 95%CI: 1.3-2.4), urban residence (OR 1.7; 95%CI: 1.3-2.1), the presence of mold in residences (OR 1.7; 95%CI: 1.0-2.3), bronchitis (OR 1.5; 95%CI: 1.2-2.0), and chronic cough (OR 1.8; 95%CI: 1.3-2.4). Further analysis, stratifying children based on their baseline health status (i.e., presence or absence of asthma, bronchitis, and chronic cough), indicated that higher parental education increased the risk of COVID-19 solely for children without pre-existing conditions. The occurrence of SARS-CoV-2 infections was found to be notably associated with mold exposure in children who did not have bronchial asthma. Rigorous multivariate analyses substantiated the collective impact of factors such as residential environment, the existence of mold and moisture, and a history of bronchitis. This study's conclusions highlight a higher frequency of SARS-CoV-2 infections in cases where bronchitis had been diagnosed previously and chronic cough was prevalent. Interestingly, the initially hypothesized higher prevalence of COVID-19 among children with bronchial asthma did not receive confirmation in our findings. This study highlights the importance of urban residence, exposure to mold or dampness, and higher parental education in the incidence of COVID-19. Higher parental education was a significant factor in increasing the risk of COVID-19 among children without bronchitis, chronic cough, and asthma.

Anthropometric Profiling and Changes in Segmental Body Composition of Professional Football Players in Relation to Age over the Training Macrocycle.

Body composition is an important indicator of the overall health and fitness of team sports athletes, including in football, and therefore, anthropometric profiling of elite football players is useful as part of determining their skills, strengths, and weaknesses to develop effective strength and conditioning programs. One of the tools available to coaches to track correlates of performance and health is routine body composition assessment. The purpose of this study is to describe and compare the body composition and anthropometric profiles of players using the Direct Segmental Multi-Frequency Bio-Electrical Impedance Analysis method, and to manage body composition throughout the round in the 2020-2021 season. The investigation was carried out during the Polish football league, PKO BP Ekstraklasa, spring round of the football season 2020-2021, in which male football players participated. Athletes between the ages of 18 and 25 (n = 16) made up the younger age group, while those between the ages of 26 and 31 (n = 22) made up the older age group. This manuscript is a continuation of the presentation of the results of the study, which was conducted between 7 January and 23 July 2021. At different stages of the macrocycle, participants underwent six different body composition analyses. The younger and older groups of athletes were compared, as well as measurements of time points 1-6. The dominant extremities, assisting extremities, and trunk had larger fat-free mass contents in the older age group. In the study groups, there was a difference in the fat-free mass content between measures 1-6 that was statistically significant. In the younger group, there was a statistically significant difference in the amount of fat mass content between measurements 1-6. In the older age group, no statistically significant changes were found. The study showed changes in fat-free mass and fat mass in body segments; differences were observed between age groups and between different moments of measurement. Age is an important factor in determining body composition and is also related to an athlete's experience and seniority. Anthropometric profiling and comprehensive body composition analysis are important tools used in preparing athletes for competition.

Salinity-induced changes in plastoquinone pool redox state in halophytic Mesembryanthemum crystallinum L.

We have analyzed the effect of salinity on photosystem II (PSII) photochemistry and plastoquinone (PQ) pool in halophytic Mesembryanthemum crystallinum plants. Under prolonged salinity conditions (7 or 10 days of 0.4 M NaCl treatment) we noted an enlarged pool of open PSII reaction centers and increased energy conservation efficiency, as envisaged by parameters of the fast and slow kinetics of chlorophyll a fluorescence. Measurements of oxygen evolution, using 2,6-dichloro-1,4-benzoquinone as an electron acceptor, showed stimulation of the PSII activity due to salinity. In salt-acclimated plants (10 days of NaCl treatment), the improved PSII performance was associated with an increase in the size of the photochemically active PQ pool and the extent of its reduction. This was accompanied by a rise in the NADP+/NADPH ratio. The presented data suggest that a redistribution of PQ molecules between photochemically active and non-active fractions and a change of the redox state of the photochemically active PQ pool indicate and regulate the acclimation of the photosynthetic apparatus to salinity.

The Incidence Proportion of SARS-CoV-2 Infections and the Percentage of Deaths among Infected Healthcare Workers in Poland.

(1) Background: The incidence proportion of SARS-CoV-2 infection among healthcare workers (HCWs) in Poland is not exactly known. This study aims to present secondary epidemiological data identifying the scale of the spread of novel coronavirus infection and the estimation of vaccination coverage in selected professional groups of HCWs in Poland. (2) Methods: The secondary epidemiological data included both the number of infections and infection fatality rate (IFR) in individual occupational groups, which occurred throughout the observation period (January 2021-July 2022), both in the country and in individual voivodeship (administrative area). (3) Results: The incidence proportion of SARS-CoV-2 infections among HCWs was 16.48%. The highest percentage of infected workers concerned laboratory scientists (21.62%) and paramedics (18%). The highest frequency of infections among HCWs occurred in the province of Zachodnio-Pomorskie (18.9%). Due to COVID-19, 558 healthcare workers died during the analysed period, mostly nurses (n = 236) and doctors (n = 200). The results regarding the vaccination coverage of HCWs against COVID-19 indicate the highest percentage of vaccinated were among doctors (83.63%) and the lowest among physiotherapists (38.2%). (4) Conclusions: In general, the percentage of infections was high in Poland during the pandemic (16.48%). Significant territorial differences were observed in the frequency of infections, deaths, and percentage of vaccinated workers in individual voivodeships.

Assessment of quality of life, pain level and disability outcomes after lumbar discectomy.

This study aimed to assess the quality of life of 113 Caucasian patients with intervertebral disc (IVD) degeneration of the lumbosacral (L/S) spine who qualified for microdiscectomy during a 12-month period after surgery. Based on magnetic resonance imaging before the surgery, the degree of radiological advancement of the degenerative changes was determined according to the Pfirrmann grading scale from 1 to 5. To assess pain intensity, the Visual Analog Scale (VAS) was used; the Satisfaction with Life Scale (SWLS) was used to evaluate quality of life; and to assess the degree of ability, the Oswestry Low Back Pain Disability Questionnaire (ODI) was employed. The level of pain, assessed using the VAS, significantly changed in the months following the surgery, with the highest values noted before surgery and the lowest a year after. In turn, the results of the SWLS questionnaire revealed a significant increase in satisfaction with life in the subsequent stages of the study. The conducted correlation analysis revealed significant dependencies in terms of quality of life in regard to pain as well as degree of disability. The level of pain and degree of disability were closely related to the degree of radiological advancement of degenerative changes according to the Pfirrmann grading scale.

Assessment of Life Satisfaction of the Physicians of the Silesian Province, Poland.

BACKGROUND: The medical profession is associated with a heavy psychological and physical burden. Specific working conditions can negatively affect the assessment of physicians' quality of life. The lack of current studies prompted us to evaluate the life satisfaction of the physicians in the Silesian Province in relation to the selected factors (health status, professional preferences, family and material status). MATERIAL AND METHODS: The study included 701 physicians and dentists from the Silesian Province aged between 25 and 80 years. It was conducted in 2018 using the Paper and Pencil Interview technique by obtaining non-personalized demographic, anthropometric, socioeconomic, occupational, health and lifestyle data. The following measures were used: the Satisfaction with Life Scale (SWLS), Occupational Satisfaction and the Hospital Anxiety and Depression Scale (HADS). Considering the environmental conditions, the total SWLS scores were analysed in terms of the significance of differences in the groups. Moreover, the SWLS scores underwent multivariate analysis of variance and the correlation analysis of job satisfaction and the presence of anxiety and/or depressive symptoms. RESULTS: Life satisfaction among the physicians and dentists from the Silesian Province was at an average level. Significant predictors included age and economic status. Additionally, significant predictors in the younger subjects (25-50 years) included the Body Mass Index and practising sports. In turn, in the older subjects (50-80 years), these predictors were related to hospital work and being on sick leave. The study found a significant moderate association between life satisfaction and professional satisfaction. Additionally, a significantly lower level of life satisfaction was reported in the subjects who presented with anxiety and/or depressive symptoms. CONCLUSIONS: Due to its association with the profession, the mean level of life satisfaction among physicians and dentists prompts verification of crucial spheres related to the physical, emotional, social and material well-being and the activity of the professional group.

Adequacy of Anaesthesia for Nociception Detection during Vitreoretinal Surgery.

Vitreoretinal surgery (VRS) is one of the most widely performed precise procedures in ophthalmic surgery; the majority of cases are carried out under regional anaesthesia (RA) only. However, in specific situations (such as when the patient fails to cooperate with the operator for various reasons), general anaesthesia (GA), alone or in combination with GA (combined general-regional anaesthesia, CGR), is the only safe way to perform VRS. While monitoring the efficacy of an intraoperative rescue opioid analgesia (IROA) during surgery (assessing the adequacy of anaesthesia (AoA)) may be challenging, the surgical pleth index (SPI) is a useful tool for detecting the reaction to noxious stimuli and allows for the rational titration of opioid analgesics (AO) during surgery. The current study investigated the influence of the SPI-based titration of fentanyl (FNT) in combination with various pre-emptive analgesia (PA) techniques on intraoperative pain perception during various stages of VRS performed under AoA. A total of 176 patients undergoing VRS under GA were enrolled in the study. They were randomly assigned to one of the five following study arms: Group GA (control group)-patients who received general anaesthesia alone; Group PBB-GA with preprocedural peribulbar block (with 0.5% bupivacaine and 2% lidocaine); Group T-GA with preventive, topical 2% proparacaine; Group M-GA with a preprocedural intravenous infusion of 1.0 g of metamizole; and Group P-GA with a preprocedural intravenous infusion of 1.0 g of paracetamol. The whole procedure was divided in four stages: Stage 1 and 2-preoperative assessment, PA administration, and the induction of GA; Stage 3-intraoperative observation; Stage 4-postoperative observation. the SPI values were monitored during all stages. The occurrence of nociception (expressed as ∆SPI >15) during various manipulations in the surgical field was observed, as were cumulative doses of rescue analgesia, depending on the PA administered. During the course of VRS, rescue FNT doses varied depending on the stage of surgery and the group investigated. The majority of patients, regardless of their group allocation, needed complementary analgesia during trocar insertion, with Group GA patients requiring the highest doses. Likewise, the highest cumulative doses of IROA were noted during endophotocoagulation in Group GA. Preventive PBB and topical anaesthesia were proven to be most efficient in blunting the response to speculum installation, while topical anaesthesia and paracetamol infusion were shown to be more efficient analgesics during endophotocoagulation than other types used PA. In the performed study, none of the PA techniques used were superior to GA with FNT dosing under the SPI with respect to providing efficient analgesia throughout the whole surgery; there was a necessity to administer a rescue OA dose in both the control and investigated groups.

Active and Happy? Physical Activity and Life Satisfaction among Young Educated Women.

BACKGROUND: Physical activity belongs to the group of health-promoting behaviors. It also affects emotional well-being, which is linked to a higher quality of life. Individuals who participate in physical activity practice regardless of age reap several positive health benefits that affect both body and mind. The aim of this study was to assess the life satisfaction of young adults in the context of physical activity undertaken. MATERIAL AND METHODS: Study material was collected via anonymous questionnaire surveys among 328 young women (between the ages of 18 and 30 with secondary or higher education) in Poland. Satisfaction with life was assessed using The Satisfaction with Life Scale (SWLS). Statistical calculations were performed using the STATISTICA 13.3 program, Stat Soft Poland. Interdependence of unmeasured characteristics was assessed using the X2 test. Multivariate analysis for the direct effect of physical activity on life satisfaction (LS) and the influence of frequency of physical fitness on life satisfaction was performed based on regular OLS multiple regression. RESULTS: The majority of respondents (74.7%) reported engaging in physical exercise. The mean level of life satisfaction was 4.5 ± 1.1 (on a scale of 1 to 7). Multivariate analysis showed no statistically significant relationship with life satisfaction in the physically active and inactive groups. It was observed that significantly higher levels of life satisfaction were found among respondents: married 5.1 ± 1.1, median = 5.2 (4.5-5.9) compared to single 4.4 ± 1.2, median = 4.6 (3.6-5.2) and in informal relationships 4.5 ± 1.0, median = 4.4 (3.8-5.2); p = 0.02; declaring rather good 4.5 ± 1.0, median = 4.6 (3.8-5.2) or very good health 4.8 ± 1.1, median = 5.0 (4.2-5.6) compared to rather poor 4.1 ± 1.0, median = 4.1 (3.4-4.8) and poor health 3.6 ± 1.4, median = 3.1 (2.6-4.4); p = 0.0006; rating their physical condition moderately 4.7 ± 1.1, median = 4.8 (4.0-5.6) or highly 4.9 ± 1.0, median = 5.0 (4.3-5.4) compared to rating their fitness low 4.2 ± 0.9, median = 4.2 (3.6-4.8); p < 0.0001. Multivariate analyses confirmed a significant effect of marital status and subjective assessment of physical condition on the average level of life satisfaction. CONCLUSIONS: Physical activity does not differentiate the level of life satisfaction in the studied group of young women. Marital status and the subjective assessment of physical condition are factors that have a significant impact on the level of satisfaction with the life of young women. Given the beneficial effect of physical activity on the sense of satisfaction with life, which can lead to an increase in its quality, physical activity should be promoted, not only among children but also in the group of young adults.

Polyspikes and Rhythmic Polyspikes During Volatile Induction of General Anesthesia With Sevoflurane Result in Bispectral Index Variations.

BACKGROUND: Although electroencephalography (EEG)-based indices may show artifactual values, raw EEG signal is seldom used to monitor the depth of volatile induction of general anesthesia (VIGA). The current analysis aimed to identify whether bispectral index (BIS) variations reliably reflect the actual depth of general anesthesia during presence of different types of epileptiform patterns (EPs) in EEGs during induction of general anesthesia. METHODS: Sixty patients receiving either VIGA with sevoflurane using increasing concentrations (group VIMA) or vital capacity (group VCRII) technique or intravenous single dose of propofol (group PROP) were included. Monitoring included facial electromyography (fEMG), fraction of inspired sevoflurane (FiAA), fraction of expired sevoflurane (FeAA), minimal alveolar concentration (MAC) of sevoflurane, BIS, standard EEG, and hemodynamic parameters. RESULTS: In the PROP group no EPs were observed. During different stages of VIGA with sevoflurane in the VIMA and VCRII groups, presence of polyspikes and rhythmic polyspikes in patients' EEGs resulted in artifactual BIS values indicating a false awareness/wakefulness from anesthesia, despite no concomitant change of FiAA, FeAA, and MAC of sevoflurane. Periodic epileptiform discharges did not result in aberrant BIS values. CONCLUSION: Our results suggest that raw EEG correlate it with values of BIS, FiAA, FeAA, and MAC of sevoflurane during VIGA. It seems that because artifactual BIS values indicating false awareness/wakefulness as a result of presence of polyspikes and rhythmic polyspikes in patients' EEGs may be misleading to an anesthesiologist, leading to unintentional administration of toxic concentration of sevoflurane in ventilation gas.

Social Inequalities: Do They Matter in Asthma, Bronchitis, and Respiratory Symptoms in Children?

Background: Social inequalities (e.g., poverty and low level of education) generate inequalities in health. Aim: The aim of the study was to determine the relationships between indicators of social inequalities and the frequency of respiratory symptoms, asthma, and bronchitis in children. Material and Methods: In 2019, an epidemiological cross-sectional study on 3237 students from elementary schools in Silesia Voivodships (South Poland) was conducted. The students' parents completed a questionnaire based on the International Study on Asthma and Allergies in Childhood (ISAAC). Social inequalities in the children's families were determined according to parents' education and professional status (working vs. unemployed), self-assessment of economic status, and housing conditions. To determine the influence of social factors on the occurrence of asthma, bronchitis, and respiratory symptoms, the odds ratio (OR) was calculated. Results: Children living in apartments with traces of mold had a higher risk of developing asthma (OR = 1.5, 95%CI: 1.17-1.96; p = 0.002) or bronchitis (OR = 1.4, 95%CI: 1.13-1.72; p = 0.002), wheezing attacks at nights (OR = 1.4; 95%CI: 1.01-1.93), wheezy in the last 12 months (OR = 1.6; 95%CI:1.24-2.08; p < 0.001), and chronic cough (OR = 1.9; 95%CI: 1.49-2.46; p < 0.001). Exposure to environmental tobacco smoke (ETS) was associated with higher risk of cough (OR = 1.5 95%CI: 1.22-1.96; p < 0.001) and dyspnea in the last 12 months (OR = 1.4; 95%CI: 1.04-2.00; p = 0.02). Low socioeconomic status (SES) was associated with increased risk of chronic cough (OR = 1.5; 95%CI: 1.09-2.03; p = 0.009) and increased risk of wheezy in the last 12 months (OR = 1.4; 95%CI: 1.06-1.97; p = 0.008). Asthma and bronchitis were not dependent on parents' education or professional status. Conclusions: Social inequalities have significant impacts on the occurrence of respiratory symptoms, bronchitis, and asthma in children. Interventions aimed at preventing bronchitis and childhood asthma should also focus on social health determinants.

The risk of respiratory incidents in response to the increase of ozone concentration in the ambient air, in the Silesian Voivodeship, in 2016-2017.

INTRODUCTION: Due to the high level of urbanization and industrialization, Silesian Voivodeship remains a region with the poorest quality ambient air, especially in the winter season in which alarm levels are constantly being exceeded. However, in the summertime, there are observed short-term episodes of high ozone concentrations for which their impact on the population health is poorly documented. The aim of the study was to assess the risk of daily respiratory health problems related to an increased pollutants concentration typical for photochemical smog. MATERIAL AND METHODS: In the ecological type of study, secondary epidemiological data were used. They were obtained from the National Health Fund (NFZ) in Katowice and included the number of outpatient visits in primary health care and hospitalizations due to respiratory diseases (J00-J99) and selected acute respiratory incidents registered between 01/01/2016 and 31/08/2017 in the Silesian Voivodeship. RESULTS: In the summertime of both years (2016 and 2017), there were observed short-term episodes of photochemical smog in the study region. Obtained results show a significant increase in the risk of outpatient visits due to total respiratory diseases, and also due to acute pharyngitis, acute laryngotracheitis, bronchitis, and asthma in response to the increase in ozone concentration. Similarly, a significant increase in the risk of hospitalization for all respiratory diseases was found, however, it appeared with a delay of at least two to three weeks. In the case of hospitalization due to bronchitis statistically significant risk was observed 2-4 days after the increase in exposure. CONCLUSIONS: The occurrence of registered respiratory incidents was confirmed in response to the increase in ozone concentration, characteristic of the summertime in the Silesian Voivodeship.

The Physical and Mental Well-Being of Medical Doctors in the Silesian Voivodeship.

Physical and mental well-being are important determinants of medical doctors' lives, including their professional activity, which has a direct impact on the health and lives of patients. The aim of the study was to assess the health condition of medical doctors from the Silesian Voivodeship. The physical health condition, including the prevalence of chronic diseases, drug therapy, and pro-health activities, was assessed. Data on mental health according to the HADS scale (hospital anxiety and depression scale) referred to the selected socio-economic and professional aspects of life, as well as life and job satisfaction. The doctors most often reported diseases of the circulatory system and diseases of endocrine system, nutritional status and metabolic changes, allergies, and degenerative changes in the musculoskeletal system and connective tissue. Chronic diseases and anxiety or depressive disorders affected doctors aged 50-80 years more frequently, and those doctors undertook preventive pro-health activities more often. The higher risks of anxiety and depression were related to their social and professional roles, lower economic status, overweight or obesity, chronic diseases, pharmacotherapy, diets, and chronic fatigue. On the other hand, frequent physical activity, a longer sleep duration, smaller weekly workload, type of rest, a higher sense of job satisfaction, and a higher level of life satisfaction reduced the risk of disorders. The health condition of medical doctors in the Silesian Voivodeship requires decisive remedial actions in the professional and non-professional spheres.

Probiotic dairy products and consumption preferences in terms of sweetness sensitivity and the occurrence of childhood obesity.

Fermented dairy products such as yogurt contain many bioactive compounds. In addition, probiotic yogurts are an invaluable source of probiotic bacteria and are a group of probiotic products best accepted by children. There is plenty of research indicating an interdependence between yogurt consumption, body mass index, and adipose tissue percentage, which suggests that yogurt consumption may contribute to reducing the risk of becoming overweight or obese. In turn, the occurrence of overweight and obesity may be accompanied by a reduced sensitivity to sweetness, which modifies food preference selection and acceptance, including with yogurt. This study aimed to assess the preferences and consumption of yogurt in terms of sensitivity to recognize sweetness and obesity in a group of 7-9-year-old children. Body mass index and adipose tissue percentage obesity indicators were determined, and the frequency of fermented milk product consumption was assessed about the results of the sweetness recognition test as well as yogurt preferences. There was no significant relationship between body weight and the frequency of fermented milk product consumption. Correlations were found between the values of body mass index and the ability to recognize sweetness, which was significantly better recognized by underweight children or at normal body weight, moreover, those children with a higher ability to recognize sweetness significantly more frequently preferred plain unsweetened yogurt.

Asthma, bronchitis respiratory symptoms, allergies and home environment: how are they related?

Introduction: Home environmental conditions can affect the prevalence of childhood asthma and allergies. Aim: To assess the relationship between the prevalence of childhood asthma, bronchitis, and allergies and the condition of the home environment. Material and methods: In 2018 and 2019, a cross-sectional study on 2932 children from elementary schools in the Silesian Voivodship (Southern Poland) was conducted. The questionnaire was based on the International Study of Asthma and Allergies in Childhood (ISAAC). In order to determine the association between the home environment (presence of moulds, furry pets) and respiratory symptoms and diseases, a logistic regression analysis was performed by calculating the odds ratio (OR), determining p < 0.05 as the level of significance. Results: Asthma risk factors were male sex, heating with solid fuel and presence of moulds. The prevalence of respiratory symptoms, bronchitis, and allergic diseases is statistically more common with the presence of moulds in dwellings. A protective effect of the presence of pets on the prevalence of asthma (OR = 0.77; 95% CI: 0.59-0.99), allergy to pet allergens (OR = 0.59; 95% CI: 0.45-0.76), allergy to house dust mite (OR = 0.70; 95% CI: 0.56-0.87) and wheeze in the last 12 months (OR = 0.70; 95% CI: 0.54-0.91) and ever (OR = 0.85; 95% CI: 0.70-1.02) was observed. Conclusions: The study confirmed the known adverse influence of the presence of moulds and heating with solid fuel on the prevalence of asthma, bronchitis, respiratory symptoms and allergic diseases. The protective influence of pets on the occurrence of the health disorders under study was demonstrated.

Clinical and molecular evaluation of patients with ovarian cancer in the context of drug resistance to chemotherapy.

The present study aimed to evaluate changes in the expression patterns at the gene and protein levels associated with drug resistance. The study group included 48 women who had a histopathologically confirmed diagnosis of stage I-IV ovarian cancer, they were divided into two subgroups (groups A and B). In group A, there were 36 patients in whom surgical treatment was supplemented with first-line chemotherapy according to current standards. Within this patient group, 5 had stage I (14%), 5 had stage II (14%), 25 had stage III (69%), and 1 had stage IV ovarian cancer (3%). Drug resistance was found after the third cycle of chemotherapy in 17 patients (71%) and after the sixth cycle in 7 patients (29%). Group B included 12 women with type I ovarian cancer, including 11 with stage I and 1 patient with stage IV ovarian cancer. The oncological treatment required only surgery. The control group (C) included 50 women in whom the uterus and adnexa were surgically removed for non-oncological reasons. Significantly higher levels of carcinoma antigen 125 CA-125 and human epididymis protein 4 HE4 were observed in group A and in menopausal women. Moreover, drug resistance was associated with significantly higher levels of CA-125 (p < 0.05). The genes UBA2, GLO1, STATH, and TUFT1 were differentiated in test samples from control samples. Moreover, drug resistance was associated with significantly higher expression of GLO1. The results of these assessments indicated the strong link between UBA2 and hsa-miR-133a-3p and hsa-miR-133b; GLO1 and hsa-miR-561-5p; STATH and hsa-miR-137-3p and hsa-miR-580-3p; and TUFT1 and hsa-miR-1233-3p and hsa-miR-2052. Correlation analysis showed a significant correlation between CA-125 and HE4 levels. Moreover, a significant correlation between TUFT1 mRNA and UBA2, GLO1, STATH (negative correlation), and TUFT1 in relation to CA-125 and HE4 (p < 0.05) was noted in all patients. In view of the lack of screening tests for ovarian cancer, the occurrence of the described correlation may be inscribed as an attempt to establish an assay that meets the criteria of a screening test and thus increase the early diagnosis of ovarian cancer.

Spatial Variability of COVID-19 Hospitalization in the Silesian Region, Poland.

Assessment of regional variation in the COVID-19 epidemic is an important task for the implementation of effective action in public health, especially in densely populated regions. In this descriptive study, the temporal and spatial variability of morbidity and in-hospital mortality of COVID-19 in the Silesian Voivodship (Poland) was analyzed. Secondary epidemiological data of hospitalized patients due to COVID-19 from 1 March to 31 December 2020 and from 1 January to 31 December 2021 were obtained from the regional registry of the Silesian Voivodship Office in Katowice. A year by year (2020 versus 2021) comparative analysis showed a similar course pattern of the COVID-19 pandemic in the Silesian Voivodeship; with the worst situation occurring in the colder months of the year. The percentage of in-hospital mortality remained at a high level, close to 20% during the second year of observation. The risk of death in patients hospitalized due to COVID-19 increased with the number of comorbidities. The highest number of patients was documented in densely inhabited regions with intensive population movement (Czestochowa and border counties). The epidemiological 'map' facilitates the generation of hypotheses needed for the explanation of the observed epidemic hazard in one of the most populated regions of Poland.

Assessment of the Socioeconomic Status and Analysis of the Factors Motivating Patients to Apply for Prosthetic Treatment by Students of Dentistry at the Poznan University of Medical Sciences.

This study aimed to determine the motives for undertaking prosthetic treatment at the Prosthetics Clinic of the Poznan University of Medical Sciences (PUMS), pursued by fifth- and sixth-year medicine and dentistry students. The survey consisted of 18 questions, of which 1 to 11 concerned general patient data, while questions 12 to 18 concerned prosthetic treatment. The only open question in the questionnaire was one regarding the motives for the decision to receive treatment. The study group consisted of 153 patients (102 women-66.67% and 51 men-33.33%) of the Prosthetic Clinic. After collecting a total of 200 questionnaires, rejecting 47 (23.50%) due to the lack of answers to all questions (other than question 18), a total of 153 completed (76.50%) questionnaires were obtained. The main motivating factors for patients to undertake prosthetic treatment are functional and aesthetic considerations. In addition, it turned out, that the authority of the university unit is of greater importance than financial issues. Additionally, some patients undergo treatment by students because they can see positive aspects in it, both for them and for students. Hence, the evaluation of the treatment provided by students, as well as their communication skills and their attitude, are rated very highly, although, again, the evaluation was influenced by the education level.
