The Influence of Electroconvulsive Therapy (ECT) on Brain-Derived Neurotrophic Factor (BDNF) Plasma Level in Patients with Schizophrenia-A Systematic Review and Meta-Analysis

The main aim of this systematic review and meta-analysis is to establish whether there is a correlation between the brain-derived neurotrophic factor (BDNF) level and electroconvulsive therapy (ECT) treatment and the reduction in psychotic symptoms in patients diagnosed with schizophrenia. A systematic search of PubMed/Medline, Cochrane Library, Web of Science, Scopus and Embase was conducted up to March 2023. Inclusion criteria: studies in which adult patients with schizophrenia treated with antipsychotic medication received ECT therapy and had the BDNF level measured before and after ECT treatment. Exclusion criteria: animal and in vitro studies or studies not involving complete information about the treatment and concentration of BDNF in plasma. The risk of bias was assessed using Egger's regression-based test for meta-analysis with continuous outcomes. Six studies comprising 248 individuals with schizophrenia were included. A statistically significant increase in BDNF levels after ECT treatment was observed only in two studies (p < 0.001 and p < 0.027, respectively), whereas in four other studies, an upward trend without statistical significance was noticed. The estimated overall size effect revealed that ECT therapy caused a slight change in the BDNF level but without statistical significance (ES = -0.328). Different numbers of ECT procedures (4-10), final measurement of the BDNF level made at a different time point, using bilateral or unilateral electrode positioning during ECT and treatment with different combinations of typical or atypical antipsychotic medications may be potential reasons for the lack of statistical significance in the changes in BDNF levels after treatment. Data regarding the measurement of BDNF levels pre and post ECT therapy in patients with schizophrenia are very limited without an extended follow-up period and evaluation of mental health change. Our meta-analysis showed that treatment with ECT therapy and antipsychotic medication increases serum BDNF levels in patients with drug-resistant schizophrenia compared to patients treated with medication only; however, this effect is not statistically significant.

The impact of the COVID-19 pandemic on physical activity, life satisfaction, anxiety, stress perception and coping strategies in student-athletes: A comparison between Belarus and Poland-countries with a different approach of anti-pandemic measures

Background

More than two years of the COVID-19 pandemic has changed lives of people around the world and had a profound impact on the field of sports. This has resulted in decreased physical activity (PA) and changes in mental health. The goal was to assess self-reported physical activity, life satisfaction, perceived stress, choice of coping strategies and their correlations among student athletes from two neighboring countries facing different anti-pandemic strategies.

Methods

Cross-sectional surveys using standardized questionnaires: International Physical Activity Questionnaire-Short Form (IPAQ-SF), Satisfaction With Life Scale (SWLS), State-Trait Anxiety Inventory (STAI), Perceived Stress Scale (PSS-10), and Coping Orientation to Problems Experienced (Mini-COPE) to compare 600 students from Physical Education and Sports departments of universities in Belarus (n = 333), where restrictions were found to be less stringent than in neighboring Poland (n = 267).

Results

Minor differences in physical activities between both countries indicate that student athletes have adapted fairly quickly and found ways to keep their PA at a fairly high level. Nevertheless, higher PA was reported in the group of student athletes from Belarus. PA levels correlated with life satisfaction, anxiety and stress levels. Female students from Poland reported lower satisfaction with their lives. Their perception of stress was twice as high as that of their Belarusian counterparts. The most common coping strategy in both groups was active coping. Polish respondents less frequently used strategies of avoiding problems and seeking outside support.

Conclusion

The level of physical activity and well-being of student athletes are associated with increased mental health and coping with stress. They also contribute to prevention of affective disorders during the COVID-19 pandemic. Moreover, it is dependent on the country's anti-pandemic policies.

Rare Occurrence of Blastocystis in Pet Animals and Their Owners in the Pomeranian Voivodeship in Poland in the Light of Literature Data

Blastocystis is an intestinal microeukaryote with ambiguous pathogenicity, commonly detected in human feces worldwide. It comprises at least 28 genetically diverse subtypes (STs), 12 of which also occur in a wide range of animal species, giving rise to suspicion of zoonotic transmission. To investigate this, we conducted a molecular study of 145 stool samples of pet animals, and 67 of their owners, living in an urban area in Poland. Blastocystis was detected in only three (2.1%) animal samples (of two bearded agamas and a leopard gecko), while all dogs, cats, and pet rodents were Blastocystis-negative. Blastocystis was also present in three (4.5%) owners of animals, but they were cat owners, not reptile owners, and the subtypes identified in them differed significantly from those of reptiles. Additionally, the frequency of Blastocystis in different groups of dogs (depending on how they were kept) was analyzed. This work is the first to find Blastocystis in pet reptiles, and we encourage further investigation of Blastocystis in this poorly examined group of animals, as well as continued study on the transmission of this microorganism between humans and animals.

The Impact of Stress-Coping Strategies and the Severity of Psoriasis on Self-Esteem, Illness Acceptance and Life Satisfaction

Introduction

The visibility of skin lesions is a significant burden for patients with psoriasis, who experience social hostility as well as many emotional and psychological problems. The recurrent nature of cutaneous manifestations and their location are also a source of emotional distress, which in turn is one of the main factors that intensifies skin lesions in these patients. The aim of the study was to assess the impact of the severity of psoriasis and stress-coping strategies on general psychometric measures in the affected patients.

Methods

The study used a short demographic questionnaire, Psoriasis Area and Severity Index (PASI), and four standardised general psychometric tools: Rosenberg Self-Esteem Scale (SES), Satisfaction With Life Scale (SWLS), Coping Inventory for Stressful Situations (CISS) and Acceptance of Illness Scale (AIS). A total of 111 patients participated in the study.

Results

The mean PASI score was 14.0 (12.1–15.9). The mean SWLS score was below average, i.e., 18.5 (17.3–19.7), and the SES score—26.8 points (26.1–27.5)—indicated self-esteem slightly above average among patients with psoriasis. The mean stress-coping level measured with CISS was 53.6 (51.9–55.2) for the task-oriented strategy (TOS), 46.2 (43.8–48.6) for the emotion-oriented strategy (EOS) and 50.1 (48.5–51.8) for the avoidance-oriented strategy (AOS). Higher PASI was associated with lower illness acceptance among men (r = 0.48) and lower self-esteem among women (r = 0.44). The level of life satisfaction was lower in respondents with higher PASI scores (mainly in the group of women, r = 0.44).

Conclusions

Higher severity of psoriasis (PASI) and greater frequency of emotion-oriented stress-coping mechanisms (CISS) are factors that negatively affect the overall psychophysical condition of respondents.

Skin-Disease Specific and Generic Psychometric Measures in Patients with Psoriasis

INTRODUCTION

Psychosocial problems of patients with chronic dermatoses, such as psoriasis, add to their somatic ailments, which results in the lack of illness acceptance, lowered self-esteem, deteriorated quality of life, and an array of somatic comorbidities. The aim of this study was to analyze the effect of psoriasis on the quality of life, sense of stigmatization, self-esteem, and satisfaction with life in patients with psoriasis.

METHODS

The study was based on a short survey prepared by the authors and five validated scales: Dermatology Life Quality Index (DLQI), 6-Item Stigmatization Scale, 33-Item Feelings of Stigmatization Questionnaire, Rosenberg Self-Esteem Scale (SES), and Satisfaction With Life Scale (SWLS). The study included 111 patients with psoriasis (46.8% women and 53.2% men). The inclusion criteria of the study were the diagnosis of plaque psoriasis and written informed consent to participate.

RESULTS

DLQI scores ranged between 0 and 28 points (pts) (mean 10.8 pts). Mean stigmatization scores determined with the 33- and 6-Item Stigmatization Scale were 81.6 pts and 7.5 pts, respectively. The mean SWLS score for the study group (18.5 pts) was slightly below the average. The mean score SES of 27 pts implies that the study respondents' self-esteem level was slightly above the average.

CONCLUSIONS

Satisfaction with life turned out to be significantly modulated by overall stigmatization level on the 33-Item Stigmatization Scale (the stronger the sense of stigmatization, the lower the satisfaction with life) and education (respondents with higher education presented with higher satisfaction with life than those with non-higher education).

Molecular Characterization of Blastocystis from Animals and Their Caregivers at the Gdańsk Zoo (Poland) and the Assessment of Zoonotic Transmission

Blastocystis is a highly genetically diverse gut protist commonly found in humans and various animals. The role of animals in human infection is only partly understood. The aim of this study was to determine the host specificity and possibility of zoonotic transmission of this microorganism. Subtypes of Blastocystis isolated from 201 zoo animals and their 35 caregivers were identified by sequencing of the SSU rRNA gene. Blastocystis was found in 26.86% of animal and 17.14% of human samples. Both mammalian (ST1-ST3, ST5, ST8, ST10, ST13, ST14) and non-mammalian subtypes were detected. Of the subtypes found in non-human primates (ST1, ST2, ST3, and ST13), two subtypes (ST1 and ST3) were also detected in humans. The presence of identical ST1 sequences in three monkeys and their caregiver indicates the possibility of direct transmission of Blastocystis between these animals and humans. Detection of ST5 only in wild boars and peccaries, ST8 only in Marsupial, ST10 and ST14 only in Bovidae, and non-mammalian subtypes in reptiles suggests higher host specificity for these subtypes, and indicates that their transmission between animals and humans is unlikely. Additionally, this was probably the first time that ST5 was found in peccaries, ST2 in patas monkeys, and ST8 in red kangaroos.

Illness Acceptance as the Measure of the Quality of Life in Moderate Psoriasis

Introduction

Psoriasis is a chronic disease with intermittent flares and remissions. Each individual perceives the disease, its somatic effects, resultant dysfunction and related problems differently. This attitude is primarily determined by one’s characterological traits and type of illness. A primary response to the diagnosis can be denial, underestimation, acceptance or overestimation of the disease. The aim of the study was to analyze the level of illness acceptance and its effect on the quality of life in moderate psoriasis depending on sociodemographic and clinical characteristics of the patients.

Materials and Methods

The study included 186 patients with plaque psoriasis with Psoriasis Area Severity Index (PASI) scores ≤10. The inclusion criteria of the study were duration of psoriasis >2 years, age ≥18 years, and lack of other somatic or mental disorders during three months preceding the study. The study participants completed the Acceptance of Illness Scale (AIS), Dermatology Life Quality Index (DLQI) as well as an original survey containing questions about their sociodemographic characteristics and information about their disease.

Results

Mean AIS score for the study group was 24.3 pts. Patients older than 40 years presented with lower levels of illness acceptance than younger persons (p = 0.0311). Also, patients’ sex and duration of psoriasis significantly affected the acceptance of the illness, with lower AIS scores found in women (p = 0.0092) and persons with a longer history of the disease (p = 0.0362). Mean DLQI score for the study group was 13.3 pts. A lower level of illness acceptance turned out to exert an unfavorable effect on the quality of life (QOL) in psoriasis (p = 0.0015; R = −0.33).

Conclusion

In this study, patients with psoriasis presented with a moderate level of the illness acceptance, and a significant correlation was found between this parameter and QOL.

Effect of Disease Severity on the Quality of Life and Sense of Stigmatization in Psoriatics

INTRODUCTION

Psoriasis is a chronic inflammatory disease of the skin having a profound effect on the quality of life and contributing to the sense of stigmatization in the affected patients. The aim of this study was to analyze the effect of psoriasis severity on the quality of life and sense of stigmatization in psoriatics and to investigate relationships between these measures and sociodemographic variables.

PATIENTS AND METHODS

The study included 111 patients with psoriasis. The inclusion criteria of the study were the diagnosis of psoriasis and written informed consent to participate. The study was based on a short survey prepared by the authors and four validated scales: Dermatology Life Quality Index (DLQI), 6-item Stigmatization Scale, 33-item Feelings of Stigmatization Questionnaire, and Psoriasis Area and Severity Index (PASI).

RESULTS

Mean PASI score for the study group was 14 pts. Most respondents presented with low DLQI scores, with the mean value of 10.8 pts suggesting that the disease-related ailments were not extremely burdensome for the majority of the patients. Mean stigmatization scores for the 6- and 33-item scale were 7-8 and 81-82 pts, respectively.

CONCLUSION

The severity of psoriasis was the strongest determinant of the quality of life measured with the DLQI. Also, the levels of stigmatization determined with the 6- and 33-item scale correlated significantly with PASI scores.

Relationships between the acceptance of illness, quality of life and satisfaction with life in psoriasis

INTRODUCTION

Since the skin plays a pivotal role in interpersonal relationships, a chronic dermatological condition (psoriasis), may have a profound effect on the psychological status of patients.

AIM

To analyse the effects of skin lesions on satisfaction with life, acceptance of illness and quality of life in psoriasis.

MATERIAL AND METHODS

The study included psoriatics recruited at the Dermatology Outpatient Unit of the Regional Hospital in Lomza, Dermatology Outpatient Clinic in Siemiatycze and Dermatology and Medical Cosmetology Centre in Bialystok. The study patients were examined with a demographic survey prepared by the authors, as well as with three validated scales: AIS, SWLS and DLQI. A total of 263 questionnaire sets were handed out to the participants of the study; this pool included 200 questionnaires with complete data that were eventually included in the analysis.

RESULTS

Acceptance of Illness Scale scores of the study participants ranged between 8 and 40 pts. Mean AIS scores for female and male psoriatics were similar, 23 and 25 pts, respectively. Based on the distribution of Satisfaction with Life Scale scores, 42 of the study patients presented with high levels of satisfaction with life, whereas 37 and 21 showed moderate and low satisfaction levels, respectively. Quality of life turned out to be the best among 20- to 30-year-old respondents as up to 74.19 of them had Dermatology Life Quality Index scores no greater than 10 pts.

CONCLUSIONS

Psoriatics with higher levels of illness acceptance also presented with greater satisfaction with life.

Quality of life in skin diseases as perceived by patients and nurses

INTRODUCTION

The appearance of the skin and its appendages not only reflects the general body condition, but also exerts an effect on one's self-esteem and self-image, and the way he/she is perceived by the others.

AIM

To analyse the quality of life (QOL) in dermatological diseases, assessed by the patients themselves and the nurses being their caregivers.

MATERIAL AND METHODS

The survey was completed by 300 patients diagnosed with various dermatological conditions; however, only the data from 281 surveys were considered during the analysis. All patients completed an anonymous questionnaire designed specifically for the purpose of the study. The survey included 32 questions. Moreover, the study patients were surveyed with the Dermatology Life Quality Index (DLQI). Moreover, the study included 1713 nurses employed in various healthcare institutions and providing care to patients with dermatological diseases. The survey for the nurses consisted of 32 questions.

RESULTS

Mean DLQI score for the study patients was 12.4 ±8.1 points. Based on the median, lower and upper quartile values, every fourth person presented with DLQI scores > 18 points, half of the respondents had DLQI scores no greater than 12 points, and every fourth respondent experienced good QOL (DLQI score no higher than 5 points).

CONCLUSIONS

According to the majority of patients and nurses, individuals with skin conditions are not fully able to cope with their disease and show a negative attitude towards it. The QOL of patients with skin diseases is determined by the type of the dermatological condition.

The Sense of Stigmatization in Patients with Plaque Psoriasis

BACKGROUND

Psoriasis is a systemic inflammatory disease capable of creating stigmatization in the form of social exclusion and decrement of psychological conditions.

AIM

The aim of the study was to determine the level of stigmatization in patients with plaque psoriasis.

METHODS

The study included 166 patients with plaque psoriasis (55.6% women and 44.3% men) with Psoriasis Area and Severity Index scores ≤10. The age of the study patients ranged between 18 and 72 years (arithmetic mean = 37.4; median = 38; standard deviation [SD] = 11.0). The mean age at the diagnosis of psoriasis was 21.5 years (median = 20; SD = 9.1) and disease duration varied from 2 to 59 years (arithmetic mean = 15.8; median = 15; SD = 11.3). The study patients completed the Polish version of the 6-item Stigmatization Scale and the 33-item Feelings of Stigmatization Questionnaire and a survey developed by the authors of this study, containing questions about the participants' sociodemographic characteristics (sex, age, place of residence, marital status, education, employment status) and information about their disease (location of psoriatic lesions, time elapsed since the diagnosis of psoriasis).

RESULTS

The mean score for the 6-item Stigmatization Scale for the whole study group was 7.6 out of 18 points (median = 7; SD = 3.8; minimum = 0; maximum = 17). The average score for the 33-item Stigma Feelings Questionnaire in our series was 84.5 out of 165 points (median = 88; SD = 20.9; minimum = 30; maximum = 136). A statistically significant sex-related difference was observed in the 6-item Stigmatization Scale scores, with higher stigmatization levels found in men than in women (p = 0.0082). Moreover, significantly higher levels of stigmatization were observed in countryside dwellers (p = 0.0311) and unmarried persons (p = 0.0321). Patients with a longer history of the disease (≥15 years) scored significantly higher on the 6-item Stigmatization Scale (p = 0.0217) than those in whom psoriasis lasted less long, and presented with higher, at the threshold of statistical significance, scores for the 33-item Feelings of Stigmatization Questionnaire.

CONCLUSIONS

Stigmatization awareness should be promoted among physicians and psoriatic patients to improve psoriasis management.

First Report on the Occurrence and Subtypes of Blastocystis in Pigs in Poland Using Sequence-Tagged-Site PCR and Barcode Region Sequencing

Blastocystis is an enteric microorganism commonly found in humans and animals worldwide. Its pathogenic role in humans and transmission patterns has not been fully explained. However, nine subtypes (ST1-8, ST12) are considered as potentially zoonotic. Studies from various regions of the world show that pigs are mainly infected with ST5. Although pigs are important farmed animals in Poland, the question of Blastocystis infection in these animals has not yet been investigated. Herein, 149 pig stool samples from 10 Polish pig farms were analyzed using sequence-tagged-site PCR and barcode region sequencing. The percentage of samples in which Blastocystis was identified using each method separately was similar: 38.25% and 37.58%, respectively. However, the percentage of positive results obtained by combining both methods was 46.97%, which means that, depending on the method used, the number of undetected samples varied between 8.72% and 9.39%. This shows the methodological limitations of up-to-date molecular approaches commonly used in Blastocystis research. A moderate infection rate (44.4-50%) observed in different pig age groups with a vital predominance of ST5 (94.28%) in every age group shows that pigs are a likely natural host of ST5. A small percentage of mixed infections, namely ST5/ST1 (5.26%), ST5/ST3 (1.75%), and ST3/ST1 (1.75%), was observed only in animals of older age, suggesting that ST3 and ST1 can be acquired by pigs during contact with humans. This study provides the first data on the prevalence and Blastocystis subtypes (STs) distribution in pigs in Poland. The results also highlight the need for the development of new methods capable of detecting highly genetically diverse Blastocystis isolates and mixed infections.

Acceptance of Illness, Satisfaction with Life, Sense of Stigmatization, and Quality of Life among People with Psoriasis: A Cross-Sectional Study

INTRODUCTION

Psoriasis is a complex disease with a heterogeneous presentation, which may have a profound effect on the everyday functioning of patients. As a strongly stressogenic disease, psoriasis may cause lack of illness acceptance and contribute to negative changes in self-image. Usually, psoriasis also has a detrimental effect on quality of life. The aim of this study is to determine the levels of illness acceptance, satisfaction with life, stigmatization, and quality of life in people with psoriasis, to analyze relationships among these variables, and to verify whether they are modulated by selected sociodemographic factors.

METHODS

A total of 366 people with psoriasis treated at the Dermatology and Medical Cosmetology Clinic in Białystok were included. The study was conducted using a short survey prepared by the authors and five validated psychometric scales: Acceptance of Illness Scale (AIS), Satisfaction with Life Scale (SWLS), 6-item Stigmatization Scale, 33-item Feelings of Stigmatization Questionnaire, and Dermatology Life Quality Index (DLQI).

RESULTS

Median AIS score was 24 pts, which corresponds to a moderate level of illness acceptance. The level of illness acceptance among men was significantly higher than among women. More than half of respondents assessed their satisfaction with life as low. Men showed low levels of satisfaction with life slightly more often than women. Patients living in the countryside showed high levels of satisfaction with life significantly more often than those living in cities/towns. Mean scores for the 6-item Stigmatization Scale and the 33-item Feelings of Stigmatization Questionnaire were 8.73 pts and 90.06 pts, respectively, with no significant differences between the results of male and female patients. The DLQI scores for the study group ranged between 0 and 30 pts, with the mean value of 17.81 pts corresponding to a severe deterioration of quality of life. Statistically significant differences between quality of life and all sociodemographic variables were demonstrated.

CONCLUSIONS

People with psoriasis participating in this study showed moderate levels of illness acceptance and stigmatization, low level of satisfaction with life, and moderately deteriorated quality of life. Acceptance of illness was significantly modulated by patient sex. The level of illness acceptance among men was significantly higher than among women. Furthermore, illness acceptance exerted a significant effect on satisfaction with life in psoriasis patients. Place of residence exerted significant effects on satisfaction with life (higher in countryside dwellers), sense of stigmatization (stronger in countryside dwellers), and quality of life (more severely deteriorated in city/town dwellers). Disease duration significantly affected the degree of life satisfaction, sense of stigmatization (measured using a 33-item Feelings of Stigmatization Questionnaire), and quality of life among patients with psoriasis.

Stigmatization and Quality of Life in Patients with Psoriasis

Introduction

Each dermatological condition associated with the presence of visible skin lesions can evoke the following psychological response of the patient: shame, anxiety, anger, or even depression. Psoriasis may additionally be a cause of social rejection, which significantly impairs a patient’s private life and social functioning, and may contribute to stigmatization, alienation, and deterioration of their quality of life. The aim of the study was to determine the level of stigmatization and the quality of life of persons with psoriasis in relation to sociodemographic characteristics.

Methods

The study, which included 166 patients with plaque psoriasis, was carried out with the 33-item Feelings of Stigmatization Questionnaire, Dermatology Life Quality Index (DLQI), and a dedicated sociodemographic survey.

Results

Compared with women, men had higher stigmatization scores in the “Feeling of being flawed” domain (p = 0.0362), and patients up to 30 years of age scored higher on the “Guilt and shame” domain (\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$\bar{x}$$\end{document}x¯ = 17.1 points) than those older than 30 years (\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$\bar{x}$$\end{document}x¯ = 14.6 points). Also, persons with visible skin lesions presented with higher stigmatization levels in the “Guilt and shame” domain than those without (p = 0.0028). Quality of life in persons with psoriasis did not depend on sociodemographic parameters but correlated significantly with two stigmatization domains, “Sensitivity to the opinions of others” (R = 0.31; p = 0.0030) and “Positive attitudes” (R = 0.27; p = 0.0115).

Conclusions

As stigmatization is a social problem, only greater social awareness of psoriasis may contribute to better understanding and broader acceptance of patients with this dermatosis. To help them to cope with the stigmatization and hence to improve their quality of life, persons with psoriasis should be provided with psychological counselling.

Occurrence of mood disorders among educationally active older adults in Bialystok, Poland: a cross-sectional study

BACKGROUND

Mood disorders in older people are an increasingly serious health and social problem, and their prevalence increases with age. The most common mood disorders are bipolar disorder, which is the occurrence of mania and hypomania, and depressive disorders. The aim of this study was to determine the prevalence of mood disorders in a group of educationally active elderly people living in Bialystok, Poland.

METHODS

The study included a total of 162 people-residents of Bialystok-aged 60 or older; 135 women (83.33%) and 27 men (16.67%). The study used five standardized psychometric scales: The Mood Disorder Questionnaire (MDQ), Hypomania Check List (HCL-32), Geriatric Depression Scale (GDS) and The Zung Self-Rating Depression Scale (Zung SDS).

RESULTS

Nearly 90.00% of the respondents obtained GDS scores indicating the presence of mild depressive symptoms; however, on the Zung SDS, which also evaluates depression symptom levels, the result obtained in almost the same number of respondents showed an absence of these symptoms. A similar percentage of respondents also obtained values on the MDQ that allow to determine a lack of bipolar disorder characteristics in the studied population. Over half of the respondents (58.02%) did not show symptoms of hypomania using the HCL-32. There was a significant correlation between the results of the GDS and Zung SDS, the HCL-32 and MDQ, as well as the HCL-32 and Zung SDS in the total studied group.

CONCLUSIONS

Mood disorders, particularly depression, constitute a significant social and health problem in the group of educationally active older adults living in Bialystok. In light of the obtained research results, it is recommended to conduct and improve already realized health education programs for the elderly on the subject of mood disorder prevention and their impact on quality of life. There is a need for further research on mood disorders in the elderly to determine their prevalence on a national scale.

Blastocystis subtypes isolated from travelers and non-travelers from the north of Poland - A single center study

Blastocystis is a common, enteric protist of humans and animals with a worldwide distribution and unclear clinical relevance. Nine out of 17 genetically diverse subtypes occur in humans. We analysed the distribution of Blastocystis subtypes and the intensity of invasion in relation to the gastrointestinal tract disorders and travels to different continents. 122 Blastocystis stool cultures were subtyped via polymerase chain reaction (PCR) with seven pairs of subtype-specific, sequence-tagged-site (STS) primers. Five subtypes of Blastocystis were detected: ST3 (59%), ST2 (19.7%), ST1 (13.1%), ST6 (3.3%), ST7 (3.3%), and two mixed infections with ST1/ST3 (1.6%). ST1 was detected exclusively in travelers to hot climate zones and ST2 was found more frequently in people visiting other continents compared to those who never left Poland. We found no correlation between gastrointestinal tract disorders, Blastocystis STs, and parasite load. There was no age predisposition to the Blastocystis infection. We established the distribution of Blastocystis STs among Poles traveling to different continents and never leaving Poland. Our study sheds more light on the problem of importing Blastocystis infection. It shows that certain subtypes detected in Europe can be imported due to travel or migration. Collecting data on the travel history of the surveyed persons is necessary to clarify this matter.

Mandatory and recommended vaccinations in Poland in the views of parents

Background: Vaccinations are currently the key element in the prevention of the spread of infectious diseases. We studied parents' opinions about mandatory and recommended preventive vaccinations in Poland. Methods: A diagnostic survey using an original questionnaire was done in a group of 300 parents. Results: A total of 3.7% of parents did not vaccinate their children. 90% were aware of the threat potentially posed by infectious diseases, and 73.7% knew that breastfeeding alone does not ensure sufficient protection against them. 28% believed that it is necessary to vaccinate a child against all diseases, 51.7% that the number of vaccinations is insufficient, and 62.7% that vaccine use is safe. 40.7% thought that unvaccinated children should not be able to attend nurseries and kindergartens, as they pose a threat to other children. Postvaccinal adverse events occurred in 21.3% of children, mainly (71.9%) an increase in body temperature above 38°C. 88.3% were informed about possible vaccine-induced complications, most often by nurses (79.7%). 88% of the respondents were aware of the possibility to switch to an alternative immunization program, 92% were informed on the possible administration of recommended vaccines, and 53% took advantage of combined vaccines. Conclusions: Views on vaccinations were mostly varied, depending on the age, sex, education, and financial situation of the respondents. Most of the parents who did not vaccinate their children believed that immunity can be acquired by infection. They were in favor of a limited number of vaccinations, were more critical of the vaccination program in Poland, considered the vaccines used in Poland to be unsafe, and blamed vaccines for multiple developmental defects and autism in children. Parents whose children experienced vaccine-induced adverse reactions were more likely to have doubts before the next vaccination.

Clinical usefulness of Western blotting and ELISA avidity for the diagnosis of human toxocariasis

The serodiagnosis of human toxocariasis is difficult. Specific IgGs detected routinely with ELISA based on Toxocara excretory-secretory (TES) antigens often persist for years at an elevated level, which does not allow either the differentiation between an active and persistent infection or monitoring of the effect of treatment. Additionally, false-positive results may occur in co-infections with other helminths due to cross-reactions. We evaluated the usefulness of an IgG avidity index (AI) and a Western blotting (WB) IgG in the diagnosis of patients suspected of Toxocara infection. We studied 138 subjects who were submitted to serological testing two or more times. Confirmation of an infection by WB was achieved in 73.2% of patients. A high AI was obtained in 89.1% of patients, and low AI and borderline AI were found in only 10.9%. Low and borderline values of AI remained at similar levels in subsequent studies over 2-3 years. The results showed the necessity of obligatory verification of all ELISA IgG positive and questionable results by WB. The index of IgG avidity may be helpful in excluding recent infection, but its usefulness in detecting an active phase of invasion requires further research.

No effect of yeast-like fungi on lipid metabolism and vascular endothelial growth factor level in children and adolescents with type 1 diabetes mellitus

Background

The objective of the research was to investigate vascular endothelial growth factor (VEGF) levels in the context of lipid metabolism and amount of yeast-like fungi colonizing the digestive tract in children and adolescents with type 1 diabetes mellitus (T1DM).

Methods

The study included 45 children with T1DM and 27 age- and sex-matched healthy control subjects. In the study sample 33 T1DM patients were administered insulin pump therapy and 12 T1DM patients were administered multiple daily injections with insulin pen devices. All T1DM patients were free of micro- and macrovascular complications. In T1DM patients and healthy controls biochemical tests were performed and measurements of yeast-like fungi colonizing the alimentary tract were conducted. Moreover all study subjects had their serum VEGF levels measured with ELISA test.

Results

The subgroup of children and adolescents with T1DM and yeast-like fungus colony number 10^³ CFU/g was shown statistically significantly lower HbA1c levels, and lower but not statistically significantly total cholesterol, LDL cholesterol and VEGF levels versus T1DM patients with the amount of yeast-like fungi 10^⁶ CFU/g. Moreover higher HDL levels were observed in this subgroup versus T1DM patients with the amount of yeast-like fungi 10^⁶ CFU/g although the difference was not statistically significant.

Conclusions

Our study has shown no influence of yeast-like fungi on lipid metabolism and VEGF level in children and adolescents with T1DM. Comprehensive treatment of T1DM patients and intensive insulin therapy with help of personal insulin pumps can reduce or prevent the development of long-term diabetic complications. Further studies in this field are needed.

Higher diversity in fungal species discriminates children with type 1 diabetes mellitus from healthy control

OBJECTIVE

To conduct qualitative and quantitative assessment of yeast-like fungi in the feces of children and adolescents with type 1 diabetes mellitus (T1DM) with respect to their metabolic control and duration of the disease.

MATERIALS AND METHODS

The studied materials included samples of fresh feces collected from 53 children and adolescents with T1DM. Control group included 30 age- and sex-matched healthy individuals. Medical history was taken and physical examination was conducted in the two study arms. Prevalence of the yeast-like fungi in the feces was determined as well as their amounts, species diversity, drug susceptibility, and enzymatic activity.

RESULTS

The yeast-like fungi were found in the samples of feces from 75.4% of T1DM patients and 70% controls. In the group of T1DM patients, no correlation was found between age (Rs=0.253, P=0.068), duration of diabetes (Rs=-0.038, P=0.787), or body mass index (Rs=0.150, P=0.432) and the amount of the yeast-like fungi isolated in the feces. Moreover, no correlation was seen between the amount of the yeast-like fungi and glycated hemoglobin (Rs=0.0324, P=0.823), systolic blood pressure (Rs=0.102, P=0.483), or diastolic blood pressure (Rs=0.271, P=0.345).

CONCLUSION

Our research has shown that children and adolescents with T1DM show higher species diversity of the yeast-like fungi, with Candida albicans being significantly less prevalent versus control subjects. Moreover, fungal species in patients with T1DM turn out to be more resistant to antifungal treatment.

[Yeast-like fungi in the gastrointestinal tract in children and adolescents with diabetes type 1]

In recent years the frequency of fungal infections in human populations has increased considerably. The most common type offungus attacking the human organism is Candida albicans. Yeast-like fungi occur naturally in the oral cavity, intestines, vagina, or skin, however in amounts not dangerous to human health. The studies so far have shown that patients with diabetes type 1 (T1DM) to a large degree are exposed to complications related to fungal infections. A substantial growth of fungi observed in diabetic patients may unfavorably affect metabolic compensation, and lead to increased demand for insulin, as well as to the difficult to cure symptom infections. The weaker the immune resistance in patients with diabetes, the greater the risk of ailments related to candidiasis. The article contains a review of recent literature regarding the problems related to occurrence of yeast-like fungi in digestive tract of children with diabetes type 1.

[Aggression as the cause of stress among physicians]

INTRODUCTION

Mental stress is inseparably connected with work. The stress reaction is favored by stagnation in life, lack of prospects for professional growth, uncertainty of stable employment, pressure to work reliably and flexibly, excessive workload, and lack of assigned duties. Interpersonal relations among members of the team represent another significant factor in the appearance and persistence of social pathology.

STUDY OBJECTIVES

Identification of forms and sources of aggression implicated in stress among physicians at the workplace.

MATERIAL AND METHODS

The study was performed in 501 physicians employed by inpatient and outpatient institutions in the province of Podlaskie. We used questionnaires assessing the intensity and type of aggression against physicians and the GHQ28 General Heath Questionnaire.

RESULTS

The patient source of stress for physicians included hostile comportment (53%) and extortion (41%). The source of stress from superiors included vulgar acts in the presence of coworkers (18%) and threats (17%). Stress was also caused by raised voice of other physicians (44%) and nurses (25%).

CONCLUSIONS

The main source of stress for physicians was aggression by patients and fellow physicians.

[Treatment problems of eosinophilic granuloma]

Two clinical cases of eosinophilic granuloma with pulmonary manifestation were observed. Therapeutical problems were discussed and corticosteroids and cytostatics were recommended.

[Results of kinesis therapy in patients with diabetic macroangiopathy of the lower extremities]

In 30 patients with diabetes type II and macroangiopathy of lower extremities, physical training was applied. This treatment was carried on in our Clinic for average 4 weeks. The following methods were applied: individual exercises of legs once or twice daily for 30-minutes, training in brine swimming pool for 30 minutes every-day, treatment walks with proportioning effort. Value of physical effort was not more than 30-40% max. pulse rate. The examination was performed before and after the programme of treatment. The examination included the following parameters: subjective test on cycloergometer, examination of blood flow velocity by Doppler method and biochemical examination of glycaemia and lipidemia. We found improvement in intermittent claudication distance, significant subjective improvement in velocity of blood flow in lower extremities. In our opinion physical vascular training is a valuable method of mono-operative treatment of vascular disease of legs in diabetic patients.
