Exposure to Stress and Burnout Syndrome in Healthcare Workers, Expert Workers, Professional Associates, and Associates in Social Service Institutions.

Background and Objectives: Workplace burnout syndrome is often as sociated with particular aspects of certain job positions, especially those that entail working with people with special needs. The burnout syndrome in healthcare jobs is a serious problem that has grown into an epidemic among healthcare workers and associates. The aim of this research is to assess the presence of stress and burnout syndrome at work with healthcare workers, expert workers, professional associates, and associates in social service institutions in Belgrade. Materials and Methods: This research was conducted in the form of a cross-sectional study of a representative sample in social institutions in Belgrade. It was conducted from March to the end of June of 2023. The sample of the study had 491 participants. The questionnaires used were a structured instrument with social-demographic and social-economic characteristics, workplace characteristics, lifestyle characteristics, and the following questionnaires: DASS-21, Copenhagen, Brief Resilience Scale, and Brief Resilient Coping Scale. Results: The end results indicate the following to be significant risk factors for the occurrence of workplace burnout syndrome: overtime (OR = 2.62; CI = 1.50-4.56), BRS average score (OR = 0.28; CI = 0.17-0.44), DASS21 D heightened depression (OR = 2.09; CI = 1.1-4.04), DASS21 A heightened anxiety (OR = 2.38; CI = 1.34-4.21), and DASS21 S heightened stress (OR = 2.08; CI = 1.11-3.89). The only protective risk factor that stood out was the self-assessment of health levels (OR = 0.60; CI = 0.42-0.85). Conclusion: Overtime is a significant factor associated with workplace burnout. Apart from it, other significant factors associated with workplace burnout were heightened depression, anxiety, and stress levels.

Influence of antipsychotics on metabolic syndrome risk in patients with schizophrenia.

Objective: Many studies so far have shown that antipsychotic therapy may have an effect on the development of metabolic syndrome in patients diagnosed with schizophrenia. Our goal was to determine whether our respondents are at risk for developing metabolic syndrome and who is more predisposed to it. Methods: In a stable phase, 60 patients diagnosed with schizophrenia were equally divided into three groups according to the drug (risperidone, clozapine, and aripiprazole monotherapy). Control group had 20 healthy examinees. Patients were evaluated first using The Positive and Negative Syndrome Scale (PANSS). Prolactin, lipid status, glycemia, insulin, cytokine values (IL-33, TGF-ß, and TNF-α) and C-reactive protein (CRP) were measured. Also, Body mass index (BMI), Homeostatic Model Assesment for Insulin Resistance (HOMA index), waist and hip circumference (WHR) and blood pressure (TA) measurement were performed in the study. Results: Patients treated with risperidone compared to healthy control subjects and aripiprazol group of patients had statistically significant difference in prolactin levels. In clozapine group compared to healthy control group values of HDL cholesterol and glucose level were statistically significant different. In aripiprazole group compared to healthy control group value of BMI was statistically significant different. Statistically significant correlations were found in TNF-α with glucose and HOMA index in risperidone treated patients and with BMI in clozapine group of patients; IL-33 with glucose in risperidone and with BMI in clozapine group of patients and TGF-ß with glucose in risperidone group, with insulin and HOMA index in clozapine group and statistically significant negative correlation with LDL cholesterol in aripiprazole group of patients. Conclusion: Patients on risperidone and clozapine therapy may be at greater risk of developing metabolic syndrome than patients treated with aripiprazole. Statistically significant difference in concentration of TNF-α and TGF-ß was in the group of patients treated with risperidone compared to healthy control group.

The significant role of dietary intake of vitamin D in non-menopausal women health.

Optimal vitamin D status is very important for reflecting not only bone but overall woman's health. The aim of the study was to determine pharmacokinetic variability of 25-hydroxy vitamin D, to reveal and quantify the most significant factors that affect its variability in the population of healthy non-menopausal women using the population pharmacokinetic (PopPK) approach. The study population consisted of 74 healthy reproductive women aged from 35 to 50 years, without the use of any supplement. A population pharmacokinetics analysis was conducted using a nonlinear mixed-effects model software. A total of 35 factors were assessed: demographic, clinical, biochemical data and lifestyle factors. The average age and bodyweight of our participants were 40.11 ± 4.35 years 65.30 ± 6.80 kg, respectively. The observed mean serum concentration of 25-hydroxy vitamin D was 26.51 ± 13.49 ng/mL with a wide range of 6.97 to 59.89 ng/mL. Development final PopPK model of the clearance of 25-hydroxy vitamin D showed that only the average daily dose of vitamin D intake from food had a significant influence, with a magnitude of its effects of 0.00401. These results could help when individualizing vitamin D intake in the form of supplements, especially during the wintertime, in healthy reproductive women.

Clinical Benefits of n-3 PUFA and ɤ-Linolenic Acid in Patients with Rheumatoid Arthritis.

(1) Background: Marine n-3 polyunsaturated fatty acids (PUFA) and ɤ-linolenic acid (GLA) are well-known anti-inflammatory agents that may help in the treatment of inflammatory disorders. Their effects were examined in patients with rheumatoid arthritis; (2) Methods: Sixty patients with active rheumatoid arthritis were involved in a prospective, randomized trial of a 12 week supplementation with fish oil (group I), fish oil with primrose evening oil (group II), or with no supplementation (group III). Clinical and laboratory evaluations were done at the beginning and at the end of the study; (3) Results: The Disease Activity Score 28 (DAS 28 score), number of tender joints and visual analogue scale (VAS) score decreased notably after supplementation in groups I and II (p < 0.001). In plasma phospholipids the n-6/n-3 fatty acids ratio declined from 15.47 ± 5.51 to 10.62 ± 5.07 (p = 0.005), and from 18.15 ± 5.04 to 13.50 ± 4.81 (p = 0.005) in groups I and II respectively. The combination of n-3 PUFA and GLA (group II) increased ɤ-linolenic acid (0.00 ± 0.00 to 0.13 ± 0.11, p < 0.001), which was undetectable in all groups before the treatments; (4) Conclusion: Daily supplementation with n-3 fatty acids alone or in combination with GLA exerted significant clinical benefits and certain changes in disease activity.

Oxidative stress in rheumatoid arthritis patients: relationship to diseases activity.

The aim of this study was to assess the oxidative stress status in rheumatoid arthritis (RA) by measuring markers of free radical production, systemic activity of disease, and levels of antioxidant. 52 RA patients and 30 healthy controls were included in the study, and clinical examination and investigations were performed and disease activity was assessed. Peripheral blood samples were used for all the assays. We assessed the markers of oxidative stress, including plasma levels of index of lipid peroxidation-thiobarbituric acid reactive substances (TBARS), hydrogen peroxide (H2O2), superoxide anion radical (O2(-)), nitric oxide (NO), and superoxide dismutase activity (SOD), catalase activity (CAT) and glutathione levels in erythrocytes. In the RA group, levels of H2O2, O2(-), and TBARS were significantly higher than in controls (4.08 ± 0.31 vs. 2.39 ± 0.13 nmol/l, p < 0.01; 8.90 ± 1.28 vs. 3.04 ± 0.38 nmol/l, p < 0.01, 3.65 ± 0.55 vs. 1.06 ± 0.17 µmol/l, p < 0.01). RA patients had significantly increased SOD activity compared with healthy controls (2,918.24 ± 477.14 vs. 643.46 ± 200.63UgHbx103, p < 0.001). Patients had significantly higher levels of pro-oxidants (O2(-), H2O2, and TBARS) compared to controls, despite significantly higher levels of SOD. Significant differences were also observed in serum levels of NO in patients with high-diseases activity. Our findings support an association between oxidative/nitrosative stress and RA. Stronger response in samples with higher diseases activity suggests that oxidative/nitrosative stress markers may be useful in evaluating the progression of RA as well as in elucidating the mechanisms of disease pathogenesis.

Late-onset systemic lupus erythematosus: clinical features, course, and prognosis.

There are contradictory opinions if late-onset systemic lupus erythematosus (SLE) is associated with a different, more benign disease course and better prognosis than early-onset SLE. The objective of this study was to evaluate the clinical manifestations, course, treatment, and prognosis of late-onset SLE. Patients who developed SLE after/or at the age of 50 years were considered late-onset SLE and compared to a group of randomly selected patients aged younger than 50 years at the diagnosis, matched for disease duration. Lower frequency of cutaneous manifestations (p = 0.01) and higher frequency of cytopenias (p = 0.02) were registrated at the SLE onset in the late-onset group. Atypical clinical presentation of SLE contributed to a longer delay of diagnosis in late-onset SLE patients (p = 0.005), who fullfiled less American College of Rheumatology criteria at the diagnosis (p = 0.022). Cumulative incidence of clinical manifestations showed lower frequency of cutaneous (p = 0.017), neuropsychiatric manifestations (p = 0.021), lupus nephritis (p = 0.006), and higher frequency of Sjogren's syndrome (p = 0.025) in the late-onset group. Late-onset SLE patients received lower doses of corticosteroid (p = 0.006) and cyclophosphamide (p = 0.001) and had more cyclophosphamide-induced complications (p = 0.005). Higher prevalence of comorbid conditions in the late-onset group (p = 0.025), and higher Systemic Lupus International Collaborating Clinics/American College of Rheumatology damage index was noticed (p = 0.018). Despite the less major organ involvement and more benign course of disease, late-onset SLE has poorer prognosis, because of the higher frequency of comorbid conditions and higher organ damage, due to the aging and longer exposition to a classical vascular risk factors.

[Colonic perforation as an unusual manifestation of Behcet's disease].

INTRODUCTION: Behcet's disease is multisystemic vasculitis which affects vein and artery blood vessels. Intestinal perforation rarely occurs as clinic manifestation in as little as 1% of patients. The transverse colon is the most infrequent site of perforation. We presented a patient diagnosed with Behcet's disease who underwent both surgical and conversative treatment due to perforation of the colon. CASE REPORT: A 34-year-old patient was admitted to the hospital with fever, aphthous ulcerations on oral mucosa and genitals and bilateral uveitis. On the basis of clinical symptoms and the International Criteria developed in 1990 Behcet's disease was diagnosed. During the next few days the patient developed erythema nodosum, diarrheic syndrome and acute abdominal symptoms due to perforation of the transverse colon. An emergent laparotomy was undertaken involving resection of a perforated segment of the colon, and bipolar colostomy on the left side of abdomen. Following the surgery the patient was treated except for antibiotics with three successive pulse doses of methylprednisolone (500 mg/daily) and cyclophosphamide (15 mg/kg). The treatment was continued by gradual decrease in the close of the corticosteroid (perorally) and by cyclophosphamide first with monthly doses (5 monthly pulse doses of 15 mg/kg cyclophosphoamide), and then with 3-month doses (totally 6 doses) up to totally 12 g. CONCLUSION: The therapy with pulse doses of methylprednisolone combined with pulse doses of cyclophosphamide was very effective in the reported case with the complex clinical manifestations leading to resolution of gastrointenstinal, ocular and orogenital lesions.

Histamine blood concentration in ischemic heart disease patients.

The aim of this study was to investigate histamine blood concentration in subjects suffering from different types of ischemic heart diseases during the period of eight days. Our results showed that the histamine blood level was associated with different types of ischemic heart diseases. The blood histamine level in all investigated patients was significantly higher when compared to control subjects (44.87 ± 1.09 ng mL(-1)), indicating the increase of histamine release in patients suffering from coronary diseases. In patients suffering from ACS-UA and ACS-STEMI, the second day peak of histamine level occurs (90.85 ± 6.34 ng mL(-1) and 121.7 ± 6.34 ng mL(-1), resp.) probably as the reperfusion event. Furthermore, our data suggest that histamine can be additional parameter of myocardial ischemia along with cardiac specific enzymes and may prove to be an excellent single prognostic marker for multitude of ischemic heart diseases.

Histamine index and clinical expression of rheumatoid arthritis activity.

BACKGROUND/AIM: Many arguments prove the pathophysiologic role of histamine in the process of remodeling and joint destruction in rheumatoid arthritis. The aim of our study was to find out if there was a relation between histamine concentration in synovial fluid and blood with clinical expression of disease activity. METHODS: Histamine concentration in synovial fluid and blood was determinated in 19 patients with rheumatoid arthritis. Histamine concentration measurement was based on the Shore's fluorometric method. Histamine index (HI) was evaluated as a ratio between histamine concentration in synovial fluid and blood. Disease activity score, DAS 28 (3), with three variables (erythrocyte sedimentation rate, the number of swelled joints and the number of tender joints) was also evaluated. RESULTS: Our results showed that there was no significant difference in concentration of histamine in synovial fluid and blood related to disease activity. However, there was a significiant difference in the histamine index which was increased proportionally with disease activity. CONCLUSION: Our study indicates that histamine index could be useful in estimation of rheumatoid arthritis activity.

Glucagon effects on ischemic vasodilatation in the isolated rat heart.

The myocardial reperfusion following ischemia leads to the ischemic vasodilation by affecting the release of various vasoactive substances, such as free radicals, NO, and histamine. In addition, some evidences suggest that glucagon itself may alter the release of those substances. In this study, we investigated the ischemic vasodilation of the isolated rat heart, as well as the concentrations of NO, TBARS, and histamine in the coronary venous effluent either in the presence or in the absence of glucagon. Our results showed that in the presence of glucagon, there was a faster restoration of coronary perfusion pressure during ischemic vasodilation compared to the absence of glucagon (124 +/- 5.6 versus 81 +/- 5.2 s) with no apparent changes in TBARS concentration. The glucagon's administration leads to the decreased release of histamine by approximately 35%. Biphasic release of NO in the presence of glucagon initially showed augmentation by 60%, followed by the significant attenuation of 45%.
