Relation of personality factors and life events to waist/height ratio and percentage of visceral fat in women and men

PURPOSE

The investigation aimed to explore the association between personality traits, stressful life events, quality of life on anthropometric characteristics (waist/height ratio and percentage of visceral fat).

METHOD

A total of 227 participants took part in this cross-sectional study. Participants completed the Social Readjustment Rating Scale (SRRS), Temperament and Character Inventory-Revised, Type-D Scale (DS-14), EuroQol Group 5-Dimension Self-Report Questionnaire (EQ-5D), and demographic questionnaire. Two anthropometric parameters were measured: Waist/height ratio and Percentage of the visceral fat.

RESULTS

The average age of participants was 39.6±12.9 years, 60.4% women. The 41.8% of participants were overweight or obese. Regression analysis found a significant link between Harm-avoidance and EQ-5D visual analog scale (VAS) with Waist/height ratio in women and Reward dependence and Cooperativeness with Waist/height ratio in men. In regression analysis, the score of life events (SRRS) has statistically significant linked to Percentage of the visceral fat in women. The regression analysis also found a significant link between Novelty seeking, DS14, Negative affectivity, and EQ-5D VAS with Percentage of the visceral fat in women.

CONCLUSION

Significant associations between live events, personality traits, and body anthropometric measures were recognized. The differences were recognized between women and men. Outcomes propose some promising tools by which personality factors may influence overweight and obesity.

Discrepancy between readiness to change, insight and motivation in alcohol-dependent inpatients

BACKGROUND

Poland, Czech Republic, and the Slovak Republic are countries with high alcohol consumption, and alcohol-induced disorders are in the ten leading causes of Years Lost due to Disability. Therefore it is necessary to study factors as insight, motivation, and readiness to change for the better understanding the variables which are in probably connected with therapeutic effectiveness.

AIM

The purpose of the study was to examine the state of readiness to change at the beginning and the end of inpatient short (six weeks) and long (12 weeks) therapeutic program in the Slovak Republic, Poland, and the Czech Republic, and look for the relationship between readiness to change, insight, and motivation in alcohol-dependent persons.

METHODS

We studied a sample of 380 alcohol-dependent inpatients (282 men and 98 women) by Alcohol Use Disorders Identification Test (AUDIT), The Stages of Change Readiness and Treatment Eagerness Scale (SOCRATES), Readiness to Change Questionnaire (RCQ), and Demographic Questionnaire.

RESULTS

The unmarried patients declare a higher severity of alcohol dependence than married or divorced ones in AUDIT questionnaire. At the beginning of the treatment, the majority of patients declared Action (68.5%) or Preparation (26.3%) motivation stage according to RCQ questionnaire. At the end of the treatment, married patients showed higher readiness to change in domain Taking steps of SOCRATES questionnaire. The unmarried patients displayed the decrease of domain Ambivalence. The duration of the completed therapeutic program may not be crucial for improvement in preparedness to change.

CONCLUSIONS

The intention and motivation to alcohol dependence treatment seem to be high at the beginning of the treatment, but recognition of the alcohol problems were low in highly dependent patients. Marital status was connected with an increased active component for readiness to change. The passive component (decreasing the ambivalence) was observed in the unmarried patients.

The differences between patients with panic disorder and healthy controls in psychophysiological stress profile

BACKGROUND

Alarming somatic symptoms, in particular, cardiovascular symptoms, are the characteristic feature of panic attacks. Increased cardiac mortality and morbidity have been found in these patients. Power spectral analysis of electrocardiogram R-R intervals is known to be a particularly successful tool in the detection of autonomic instabilities in various clinical disorders. Our study aimed to compare patients with panic disorder and healthy controls in heart rate variation (HRV) parameters (very-low-frequency [VLF], low-frequency [LF], and high-frequency [HF] band components of R-R interval) in baseline and during the response to the mental task.

SUBJECTS AND METHODS

We assessed psychophysiological variables in 33 patients with panic disorder (10 men, 23 women; mean age 35.9±10.7 years) and 33 age- and gender-matched healthy controls (10 men, 23 women; mean age 35.8±12.1 years). Patients were treatment naïve. Heart rate, blood pressure, muscle tension, and HRV in basal conditions and after the psychological task were assessed. Power spectrum was computed for VLF (0.003-0.04 Hz), LF (0.04-0.15 Hz), and HF (0.15-0.40 Hz) bands using fast Fourier transformation.

RESULTS

In the baseline period, the VLF band was significantly lower in panic disorder group compared to controls (p<0.005). In the period of mental task, the LF/HF ratio was significantly higher in panic disorder patients compared to controls (p<0.05). No significant differences were found in the remaining parameters. There was a significant difference in ΔHF and ΔLF/HF ratio between patients and controls, with Δ increasing in patients and decreasing in controls.

CONCLUSION

These findings revealed that patients suffering from panic disorder were characterized by relative sympathetic dominance (reactivity) in response to mental stress compared with healthy controls.

Life events, quality of life, autonomic nervous system, and cardiovascular risk factors

Background

Psychological distress is considered as a component of the cardiovascular risk. The present study aims to determine which psychophysiological, electrocardiographic and anthropometric factors are correlated with life events, depression and quality of life in healthy adults.

Method

A total of 114 adults were examined using the Social Readjustment Rating Scale, the EuroQol Group 5-Dimension Self-Report Questionnaire, Beck Depression Inventory – Second Edition, Zung Self-Rating Depression Scale. Physiological measures included heart rate variability, skin conductance level and skin temperature. Anthropometric characteristics included weight, height, hip size, waistline, blood pressure, heart rate at rest and after mental activity, muscle mass, fat stock, percentage of the body fat, segmental distribution of muscle and fat mass, fat-free mass and the water content in the body. Finally, data from electrocardiographic examination included aortic pulse wave velocity, central aortic pressure and augmentation index.

Results

Life events in last two years correlate with worse quality of life and a higher level of depression. Life events in last two years also correlate with the increase of the risk factors for cardiovascular problems in terms of several anthropometric and physiological measures. Finally, life events in last two years was also related with the overweight.

Conclusions

Results suggest some possible mechanisms by which stress may exert adverse effects on cardiovascular morbidity and mortality in healthy persons. Primary preventive strategies with the stress management training may prove beneficial.

Coping, schemas, and cardiovascular risks - study protocol

The aim of this article is to describe the protocol of a trial focusing on the psychological, anthropometric, cardiac, and psychophysiological factors contributing to increased risk of cardiovascular diseases (CVDs). As background, the article provides a short overview of research literature linking personal traits, maladaptive schemas, and coping styles with CVDs through reactivity of the autonomic nervous system.

Which psychological, psychophysiological, and anthropometric factors are connected with life events, depression, and quality of life in patients with cardiovascular disease

OBJECTIVE

The aim of the study was to determine psychological, psychophysiological, and anthropometric factors connected with life events, level of depression, and quality of life in people at risk for cardiovascular disease and healthy controls.

METHODS

This is a cross-sectional study involving arterial hypertension patients and healthy controls. There were several measurements including physical, anthropological, cardiovascular, and psychophysiological measurements and administration of questionnaires.

RESULTS

A total of 99 participants were recruited for this study, 54 healthy controls (mean age: 35.59±13.39 years) and 45 patients with cardiovascular disease (CVD) (mean age: 46.33±12.39 years). The healthy controls and the patients with CVD significantly differed in the mean total score of life events, level of depression, quality of life score, temperature, blood pressure (BP), pulse transit time, heart rate, high-frequency total power, heart rate variability total power, waist-to-height ratio (WHtR), body fat percentage, fat control, pulse wave velocity, and augmentation index. In healthy subjects, the total score of the life events was not correlated with any cardiovascular or anthropometric factor. A score of depression significantly correlated with the WHtR, augmentation index, body fat percentage, and fat control. The quality of life - visual scale correlated with the body temperature, BP, and percentage of body fat. In the group of the patients with CVD, the score of the life events did not correlate with any measured cardiovascular or anthropometric factor. The level of depression correlated with the augmentation index. The quality of life - visual scale significantly correlated with body temperature, WHtR, and fat control.

CONCLUSION

The patients with CVD reported higher scores of life events, worse quality of life, and a greater level of depressive symptoms than healthy controls. In healthy controls, a higher mean total score of life events significantly negatively correlated with high-frequency total power, and the degree of depression correlated with being overweight. In patients with CVD, a score of depression was linked to being overweight.

Synthesis and biological activity of 6-substituted-3-[2-(5-substituted-2-furfurylidenehydrazino)-4-thiazolyl] coumarins

A series of coumarin-derivatives (5) were synthesized by the reaction of 5-substituted-2-furfuraldehyde thiosemicarbazones with 3-bromoacetyl-6-substituted coumarins. The structures of newly synthesized compounds were confirmed on the basis of their elemental analysis, NMR and mass spectral data. Some selected compounds were screened for their antibacterial activity employing disc diffusion technique.

Prolonged release biodegradable vesicular carriers for rifampicin--formulation and kinetics of release

An attempt has been made to design suitable liposome and niosome-encapsulated drug delivery system for rifampicin and evaluated the same in vitro and in vivo. A modified lipid layer hydration method was employed to prepare these vesicular carriers. The formulated systems were characterized in vitro for size distribution analysis, drug entrapment, drug release profiles and vesicular stability at different conditions of storage. In vivo drug kinetics was evaluated in normal, healthy albino rats for niosomal formulation upon subcutaneous injection and various pharmacokinetic parameters were determined. Niosomes and liposomes exhibited mean diameter of 9.73 and 11.87 microns with entrapment efficiencies of 30.5 and 34.2% respectively. Both the products exhibited sustained release characteristics in vitro with zero order drug release kinetics up to initial 10 hr. Stability evaluation indicated that both formulations were not significantly leaky over a period of one month. Niosomal formulation elevated plasma elimination half life and decreased elimination rate constants for rifampicin in vivo suggested that encapsulation retarded the removal of the drug from circulation compared to free drug due to slow drug release into systemic circulation. A five-fold increase in the area under plasma rifampicin concentration-time curve for niosomal rifampicin as compared to free drug indicated better bioavailability of encapsulated drug. It is evident from this study that niosomes and liposomes could be promising delivery systems for rifampicin with prolonged drug release profiles and reasonably good stability characteristics.

Fish meal extract bile esculin agar (FMBE) a selective medium for Bacteroides fragilis group

Fish meal extract bile esculin agar (FMBE) is prepared using Fish meal extract concentrate as the basal substance, for the selective isolation and presumptive identification of B.fragilis group. The efficiency of the medium was evaluated by growing stock cultures of B.fragilis groups as well as inoculating clinical specimens and comparing the results with Bacteroides bile esculin agar (BBE). All the 87 stock cultures of B.fragilis grew on FMBE and BBE. No other anaerobes tested grew on the medium. However 7 out of 65 neomycin resistant aerobes grew on the FMBE. From the 100 clinical samples, 62 strains of B. Fragilis group were recovered on FMBE and BBE, and 53 strains on supplemented BHIBA. The cost effectiveness, selectivity and the ability to detect esculin hydrolysis will enable FMBE as a suitable medium as comparable to that of BBE, if not superior.

Viral diarrhoea in a rural coastal region of Karnataka India

A total of 106 children below 5 years of age admitted to the Kasturba Medical College Hospital Manipal Karnataka (South India) were investigated over a period of 6 months to determine the aetiological role of viruses in acute diarrhoea. Viral aetiological agents isolated were Rotaviruses in 12 (11 per cent) cases, Adenoviruses in 3 (3 per cent) cases, coronavirus and astroviruses in two (2 per cent) cases each. Non-viral isolates were Cryptosporidium and Salmonella typhimurium in two cases each, and Entamoeba histolytica and Shigella flexneri in one case each.

Bacterial flora of the endometrium in infertile women from Manipal

Endometrial curettage specimen culture of 140 infertile women showed 64 (45%) organisms. Mycobacterium tuberculosis 8 (5.7%) and Anonymous mycobacteria 14 (10%) were the commonest organisms isolated. Among the anonymous mycobacteria, following species were isolated M. scrofulaceum 10, M. kansasii 2, M. fortuitum 2. Gram positive and gram negative organisms were isolated from 42 (30%) specimens of the endometrium; 76 (54%) of the endometrium specimens were sterile.

Pulmonary infections by atypical mycobacteria in a rural coastal region of Karnataka, India

The sputum specimens from 6,829 cases were obtained from patients diagnosed as "relapsed cases" of pulmonary tuberculosis and chronic non-specific respiratory diseases (CNSRD). Of these 1,191 (17.4%) were culture positive for acid fast bacilli with 292 (4.23%) human and 899 (13.7%) being atypical mycobacteria. These data imply that, if not all, most of the reported cases of relapsed pulmonary tuberculosis could be due to atypical mycobacteria in South West Coast of India and that this agent in some patients could be responsible for chronic infections of the lung as well. Practically all of these patients are from rural areas living in close contact with nature and animals. This poses the question whether atypical mycobacterial infection could be considered a zoonosis.
