Impact of the COVID-19 pandemic on the development of burnout syndrome in healthcare providers: prevalence and predictive factors.

BACKGROUND: In Tunisia, the pandemic is still ongoing, resulting in the burnout of healthcare providers. AIMS: This study aimed to assess the impact of the management of COVID-19 patients on the physical and mental health of healthcare providers, and to identify the independent and predictive variables for the three components of severe burnout: emotional exhaustion, depersonalization, and lack of personal accomplishment at work. METHODS: It was a cross-sectional survey. Data were collected between February 8, and April 11, 2021. Healthcare providers, who were positive for COVID, completed the questionnaire. The primary endpoint was to assess the degree of burnout in healthcare providers by adopting the original version of the severe Maslach Burnout Inventory: emotional exhaustion (≥30), depersonalization (≥12), and lack of personal accomplishment at work (≤ 33). A descriptive analysis followed by a bi- and multivariate analysis was performed to identify independent and predictive factors for each component of burnout. RESULTS: 700 healthcare providers were audited. Emotional exhaustion was ≥ 30 in 86%, depersonalization was ≥ 12 in 61%, and lack of personal accomplishment at work was ≤ 33 in 69%. Of the 700 healthcare providers, 93% were working at the same time in the COVID units, 85% had not received compensatory rest. Healthcare provider who had been infected by COVID-19 was the only independent predictive variable of severe emotional exhaustion and severe depersonalization. Healthcare provider who had been infected by COVID-19 and did not have a compensatory rest were two independent predictive variables of severe lack of personal accomplishment at work. CONCLUSION: Healthcare provider who had been infected by COVID-19 was the only predictive variable of severe emotional exhaustion and severe depersonalization. Healthcare provider who had been infected by COVID-19 and did not have a compensatory rest were two independent and predictive variables of severe lack of personal accomplishment at work.

Effectiveness of acetazolamide for reversal of metabolic alkalosis in weaning COPD patients from mechanical ventilation.

PURPOSE: To evaluate the effects of a single daily dose of acetazolamide (ACET) on metabolic alkalosis and respiratory parameters in weaning chronic obstructive pulmonary disease (COPD) patients from invasive mechanical ventilation. DESIGN: Case-control study. SETTING: An 18-bed intensive care unit (ICU) in a university hospital. PATIENTS: Twenty-six intubated COPD patients with mixed metabolic alkalosis (serum bicarbonate >26 mmol/l and arterial pH >or=7.38) were compared with a historical control group (n = 26) matched for serum bicarbonate, arterial pH, age, and severity of illness at admission to ICU. ACET administration (500 mg intravenously) was monitored daily according to arterial blood gas analysis from readiness to wean until extubation. RESULTS: ACET was administered 4 (1-11) days throughout the weaning period. Patients with ACET treatment significantly decreased their serum bicarbonate (p = 0.01 versus baseline) and arterial blood pH (p < 0.0001), increased their PaO(2)/FiO(2) ratio (p = 0.04), but did not change their PaCO(2) (p = 0.71). Compared with matched controls, administration of ACET did not improve arterial blood gas and respiratory parameters except PaO(2)/FiO(2) ratio (p = 0.03). ACET patients and their matched controls had similar duration of weaning. Extubation success rate was not significantly different between groups, and causes of reintubation were comparable. CONCLUSIONS: ACET used at the dosage of 500 mg per day reduces metabolic alkalosis but has no benefit in terms of improving PaCO(2) or respiratory parameters in weaning COPD patients from mechanical ventilation.

Compressive pleural effusion after ovarian hyperstimulation syndrome--a case report and review.

OBJECTIVE: To report a case of early onset ovarian hyperstimulation with massive pleural effusion and respiratory failure before IVF. DESIGN: Case report. SETTING: University teaching intensive care unit. PATIENT(S): A 26-year-old healthy woman with an unexplained infertility transferred to the intensive care unit on day 4 after hCG injection for early severe presentation of ovarian hyperstimulation syndrome with massive compressive pleural effusion before she underwent embryo transfer. INTERVENTION(S): Mechanical ventilation, thoracocentesis. MAIN OUTCOME MEASURE(S): Resolution of symptoms/stopping of embryos transfer. RESULT(S): Drainage of 5,300 mL of sterile exudative pleural fluid for a period of 48 hours, which permitted resolution of symptoms and allowed mechanical weaning. The IVF procedure was stopped. CONCLUSION(S): This case described is unusual in that the patient presented with early massive pleural effusion on day 4 after hCG injection and before embryo transfer. This is much earlier than in any case report elsewhere.

Prognostic value of human erythrocyte acetyl cholinesterase in acute organophosphate poisoning.

Acute organophosphate poisoning (OPP) such as dichlorvos may be monitored by the measurement of the erythrocyte acetyl cholinesterase (EAChE) and the serum cholinesterase (SChE) activities. The aim of this study was to look at correlation between the severity of the OPP judged by certain parameters such as coma, hemodynamic disturbances, respiratory failure, and the decrease of cholinesterases enzymes including EAChE and SChE at admission. Cholinesterase activity was determined upon admission and then on days 3 and 15 in the morning. Clinical effects, EAChE, and SChE activities data were investigated in 42 patients with OPP aged of 29.6 +/- 11.8 years with acute cholinergic crisis in all cases. They were comatose in 29% of cases, presenting both hypotension or shock and hypoxemia in 17% of cases. Fifteen of them (36%) required mechanical ventilation. The mean EAChE activity at admission was 24.3 +/- 11.6 micromol/mL per hour at 37 degrees C; it was 1260 +/- 2204 IU/L for SChE. There were no correlations between the EAChE and the SChE activities. The EAChE was decreased only in comatose patients and those presenting hypotension, hypoxemia, and bradycardia with a cutoff of 23.5 micromol/mL per hour at 37 degrees C. Death was observed in 2 patients with a deep decrease of the EAChE at 5 micromol/mL per hour at 37 degrees C in 1 case and 9 micromol/mL per hour at 37 degrees C in another. The kinetics of improvement of the EAChE activity below the cutoff showed the absence of statistical improvement of the EAChE activity on day 3 (16.6 +/- 9 vs 19.5 +/- 5.7 micromol/mL per hour at 37 degrees C); this improvement was remarkable on day 15 (16.6 +/- 9 vs 27.5 +/- 6.5micromol/mL per hour at 37 degrees C, P = .0004). In summary, the marked decrease of EAChE activity appears in this study as prognostic factor in acute OPP, and coma, respiratory failure, hemodynamic disturbances, and death are associated with a decrease of the EAChE of less than 23.5 micromol/mL per hour at 37 degrees C.

[Hypertrophic cardiomyopathy in Freidreich ataxia: about two cases]. / Cardiomyopathie hypertrophique dans le cadre d'une maladie de Freidreich: a propos de deux cas.

Freidreich ataxia is the most frequent ataxia of early onset and of autosomal recessive transmission. It is associated with hypertrophic cardiomyopathy in 34 to 77% of cases. The purpose of this article is to describe the cardiac manifestations of two patients affected by this disease. The first case report is about a 34-years-old, bedridden male patient having muscular hypotony and osteotendinous areflexia of the lower limbs. Chest x-ray findings showed a cardiac silhouette distorted by scoliokyphosis. ECG revealed frequent auricular extrasystoles. Cardiac US examination disclosed a pattern of concentric hypertrophic cardiomyopathy with systolic and diastolic dysfonction.
