Diet quality and eating patterns in euthymic bipolar patients.

OBJECTIVE: As mood disorders and obesity are interrelated, and both are linked to increased morbidity and mortality, risk factors for obesity should be identified and closely monitored in patients with bipolar disorder (BD). The aim of this study was to determine the diet quality of BD patients and to investigate its putative associations with comorbid obesity and disorders of carbohydrate metabolism, as well as the relationship between diet and clinical features of BD. PATIENTS AND METHODS: Eating patterns in 113 euthymic BD patients and 160 healthy control subjects were assessed using data obtained from a food frequency questionnaire. Associations of diet quality with subjects' weight, waist circumference (WC), insulin resistance index and clinical features of BD were also analyzed. RESULTS: BD patients had lower Mediterranean Diet Score than controls. Using principal analysis, four dietary patterns were revealed in the BD group (western-type, pro-healthy carbohydrates, unhealthy snacks, and meats and potatoes). Over 70% of patients with BD had Body Mass Index above 25kg/m2. The values of Fasting Triglycerides Glucose Index and WC were significantly higher in BD patients than in the control group. No significant association between diet quality indices and the clinical course of BD was found. CONCLUSIONS: In our work, euthymic bipolar patients showed unhealthy dietary patterns and had lower adherence to the Mediterranean diet than the controls. Increased values of insulin resistance indicators in the BD group point to the necessity of monitoring glucose and triglycerides levels and measurement of waist circumference in bipolar patients in the routine clinical practice. The cooperation between psychiatrists, dieticians and other medical professionals are necessary to develop dietary recommendations for patients with bipolar disorder.

Seasonality of food groups and total energy intake: a systematic review and meta-analysis.

BACKGROUND/OBJECTIVES: The aim of this systematic review and meta-analysis was to assess the effect of season on food intake from selected food groups and on energy intake in adults. SUBJECTS/METHODS: The search process was based on selecting publications listed in the following: Medline, Scopus, Web of Science, Embase and Agris. Food frequency questionnaires, 24-h dietary recalls and food records as methods for assessment of dietary intake were used to assess changes in the consumption of 11 food groups and of energy intake across seasons. A meta-analysis was performed. RESULTS: Twenty-six studies were included. Articles were divided into those reporting data on four seasons (winter, spring, summer and autumn) or on two seasons (pre-and post-harvest). Four of the studies could be utilized for meta-analysis describing changes in food consumption across four season scheme: from winter to spring fruits decreased, whereas vegetables, eggs and alcoholic beverages increased; from spring to summer vegetable consumption further increased and cereals decreased; from summer to autumn fruits and cereals increased and vegetables, meat, eggs and alcoholic beverages decreased; from autumn to winter cereals decreased. A significant association was also found between energy intake and season, for 13 studies reporting energy intake across four seasons (favors winter) and for eight studies across pre- and post-harvest seasons (favors post-harvest). CONCLUSIONS: The winter or the post-harvest season is associated with increased energy intake. The intake of fruits, vegetables, eggs, meat, cereals and alcoholic beverages is following a seasonal consumption pattern and at least for these foods season is determinant of intake.

Factors contributing to cognitive deficits in elderly residents of rural areas.

OBJECTIVE: Due to the growing aging of societies an increasingly large group of people suffers from age-related impairment of cognitive functions and thus reducing the quality of life of the elderly. The purpose of the study was to evaluate the efficiency of cognitive functions in a group of aging residents of rural areas. PATIENTS AND METHODS: The inhabitants of a rural area were recruited and assessed: cognitive function as well as intellectual and physical activity, number of years of education, presence of diseases, using stimulants, diet, sources of living, marital status and family situation Subjects were divided into two groups: persons above 65 and older, constituting the studied group and persons between 40 and 64 years of age, constituting the control group. Both groups did not significantly differ in terms of sex or years of education. RESULTS: Statistically significant differences (p < 0.05) were found in the results of the tests concerning such functions as the sight recognition memory and spatial recognition memory, spatial operating memory both on the strategy level and on the level of committed errors. An analysis of the results obtained in the group of elderly people did not indicate any major differences between men and women as regards the analyzed cognitive functions, no statistically significant differences were found in cognitive testing depending on the number of years of education. The studied persons included in the physically active group scored better in the visual memory and learning tests. CONCLUSIONS: The conducted studies elucidated the dependence of the level of cognitive functions on age, a positive impact of physical activity on some cognitive functions, however we could not find differences between the efficiency of those functions and education, sex, presence of somatic diseases and activity of persons aged > 65.

Association of cognitive performance with the physical activity and body mass index in middle-aged and older rural inhabitants.

OBJECTIVE: Last few decades have witnessed rapid ageing of the population. The prevalence of mild cognitive impairment and dementia is significantly higher in people aged 60 and over than in younger. The aim of the study was the assessment of the putative associations between physical activity and cognitive functioning in elderly inhabitants of a rural area. PATIENTS AND METHODS: The participants underwent physical assessment, physical activity, cognitive functions, depression were assessed. RESULTS: Highly active participants had better results in tests assessing psychomotor speed and in measuring attention and its flexibility comparing to groups of medium and low physical activity. Active people made fewer errors in the test measuring visual memory and new learning, and had significantly better results in the spatial-recognition memory test. Persons with symptoms of depression performed worse in visuospatial memory and working memory tests. Associations between physical activity and cognitive test results as well as association between body mass index and blood pressure and cognitive performance were observed. CONCLUSIONS: The results of the study suggest an association between higher physical activity and better cognitive functioning in the field of working memory and visual and spatial-recognition, attention and attention flexibility. Symptoms of depression, hypertension and increased BMI may adversely affect cognitive performance in elderly.

Obesity itself does not influence BDNF serum levels in adults.

OBJECTIVE: In European countries more than 50% of the population are overweight, 30% with obesity. In Poland overweight was present in 41% of men and 28.7% of women (obesity 15.7% and 19.9%). It was examined whether obesity affects serum levels of brain-derived neurotrophic factor (BDNF) and interleukin-6 (IL-6), which may lead to the consequences of obesity, such as type 2 diabetes, hypertension, and finally the metabolic syndrome. We aimed to examine whether obesity affects the serum levels of BDNF and IL-6. PATIENTS AND METHODS: The study involved 144 people aged 45 to 86 years, 80 subjects with diagnosed obesity and 64 with normal body weight, ≤ 65 years old (n = 45) and > 65 years old (n = 99). All patients underwent tests of glucose, total cholesterol, HDL, LDL, triglycerides levels, using routine laboratory methods. A test of the concentration of IL-6 and BDNF was carried out. The declared level of physical activity (gymnastics, cycling or walking) was considered. RESULTS: It was shown that in women ≤ 65 years old, obesity was associated with higher levels of interleukin-6. When the test group, divided into the above categories, was analyzed for the diagnosis of hypertension, heart failure or diabetes mellitus, no statistically significant differences in the investigated parameters were detected. The concentration of brain-derived neurotrophic factor did not differ in the investigated subjects, regardless of sex, age, obesity, or the declared physical activity. CONCLUSIONS: The concentration of interleukin-6 in younger people, including those with normal body weight, correlated with total cholesterol and triglyceride levels, and it was significantly higher in obese women compared to those with normal body weight.

Use of the Hypomania Checklist-32 and the Mood Disorder Questionnaire for detecting bipolarity in 1051 patients with major depressive disorder.

PURPOSE: To use the hypomania checklist (HCL-32) and the mood disorder questionnaire (MDQ), for detecting bipolarity in depressed patients. PATIENTS: One thousand and fifty-one patients fulfilling ICD-10 criteria for unipolar major depressive episode, single or recurrent, were studied. Patients were assessed using a structured demographic and clinical data interview, and by the Polish versions of the HCL-32 and MDQ questionnaires. RESULTS: Hypomanic symptoms exceeding cut-off criteria for bipolarity by HCL-32 were found in 37.5% of patients and, by MDQ, in 20% of patients. Patients with HCL-32 (+) or MDQ (+) differed significantly from patients with HCl-32 (-) and MDQ (-) respectively, by being less frequently married, having more family history of depression, bipolar disorder, alcoholism and suicide, earlier onset of illness, and more depressive episodes and psychiatric hospitalizations. The percentage of patients resistant to treatment with antidepressant drugs was significantly higher in HCL-32 (+) vs. HCL-32 (-) and in MDQ (+) vs. MDQ (-): 43.9% vs. 30.0%, and 26.4% vs. 12.4%, respectively. CONCLUSIONS: The results confirm a substantial percentage of bipolarity in major depressive disorder. Such patients have a number of clinical characteristics pointing on a more severe form of the illness and their depression is more resistant to treatment with antidepressants.

Quality of life, depressive symptoms and anxiety in hyperthyroid patients.

PURPOSE: The aim of the study was to evaluate quality of life and to assess frequency and severity of depressive and anxiety symptoms in hyperthyroid patients. MATERIAL AND METHODS: Forty-seven hyperthyroid patients (38 female, 9 male, mean age 51.4 +/- 13.0; 25-Graves disease, 22 - nodular goitre) and fifty-eight sex- and age-matched controls (40 female, 18 male, mean age 49.6 +/- 16.0) were studied. Quality of life was assessed by means of WHO QuoL Questionnaire. Psychometric evaluation included assessment of depressive symptoms (Hamilton Depression Rating Scale and Beck Depression Inventory) and anxiety level (State and Trait Anxiety Inventory--STAI). RESULTS: Patients presented significantly decreased perception of quality of life and health state, and scored worse in physical domain and global score of WHO QuoL. Nineteen patients showed depressive symptoms, remaining 28 were euthymic. Level of anxiety did not differ significantly between the patients group and controls. Free thyroxine plasma level correlated with psychological domain of QuoL. Depression severity correlated with anxiety (STAI 2). Anxiety as a state marker influenced psychological and environmental domains and global score of quality of life questionnaire. CONCLUSIONS: The influence of hyperthyroidism on the quality of life was observed. Depressive symptoms are frequent in hyperthyroidism, occurring in 40% hyperthyroid patients. We found also the association between the anxiety level and the quality of life.

[Carrier status of Staphylococcus aureus among students of different courses]. / Nosicielstwo Staphylococcus aureus wsród studentów roznych Kierunków nauczania.

Staphylococcus aureus is a frequent pathogen of nosocomial infections. The main part in the spread of these microorganisms take symptomless carriers. The aim the research was defining the carrierstate of S. aureus among students of Medical Academy and University. The investigation showed a greater carrierstate in the group of Medical students (33%) than in the group of University students. Strains isolated from the Medical students were more differentiated in biochemical tests and they were more drug-resistant mainly to Augmentin (51.5% resistant strains) and doxycycline (24% resistant strains). A great percentage of ampicillin-resistant strains (94%) was found among the strains isolated from both groups. Results of the research showed greater carrierstate among people who had direct contact with patients and infectious materials and proved a wide range of drug-resistance among hospital strains. Carriers of S. aureus among medical personnel could influence the spreading of nosocomial infections mainly on ICU and Newborn Wards.
