With 23.5 suicide-related deaths per 100 000 population, South Africa (SA) has the eighth-highest age-standardised suicide rate in the world. Intentional self-poisoning is associated with significant ...morbidity, mortality and cost. In SA, self-poisoning is the leading method of suicide in females and the second leading method in males. To determine the profile of patients presenting with intentional self-poisoning to the Charlotte Maxeke Johannesburg Academic Hospital emergency department. The study was a cross-sectional, retrospective audit of the medical records of patients who presented over a 12-month period with intentional self-poisoning.Of the 288 patients included, 62.8% were female, 62.1% were aged 18 - 30 years, 22.2% were foreign nationals, 88.9% were single, 62.8% were unemployed, 82.3% reported that the episode was precipitated by an acute stressful event, 5.6% required intensive care unit (ICU) admission, and 4.5% died prior to hospital discharge. Organophosphate/carbamate pesticide ingestion was the most common method of self-poisoning (25.3%) and was responsible for the majority of ICU admissions (81.3%), cases requiring hospitalisation for >6 days (56.5%) and deaths (69.2%).A large proportion of patients were female, 18 - 30 years of age, single, unemployed, and reported an acute stressful event as a precipitant. Organophosphate/carbamate pesticide ingestion was the most common method of self-poisoning and accounted for the majority of deaths and ICU admissions. Nationwide efforts should be aimed at enhancing awareness and implementing strategies to identify those at increased risk of suicidal behaviour.
South Africa (SA) has a high prevalence of HIV and tuberculosis. Cape Town was the SA metropole most affected in the early stages of the COVID-19 pandemic. Early observational data from Africa may ...provide valuable insight into what can be expected as the pandemic expands across the continent.
To describe the prevalence, clinical features, comorbidities and outcome of an early cohort of HIV-positive and HIV-negative patients admitted with COVID-19.
This was a descriptive observational study of an early cohort of adults with COVID-19 pneumonia admitted from 25 March to 11 May 2020.
Of 116 patients (mean age 48 years, 61% female) admitted, 24 were HIV-positive (21%). The most common symptoms reported were cough (n=88; 73%), shortness of breath (n=78; 69%), fever (n=67; 59%), myalgia (n=29; 25%) and chest pain (n=22; 20%). The most common comorbidities were hypertension (n=46; 41%), diabetes mellitus (n=43; 38%), obesity (n=32; 28%) and HIV (n=24; 21%). Mortality was associated with older age (mean (standard deviation) 55 (12) years v. 46 (14) years; p<0.01); the presence of hypertension or hypertension along with diabetes and/or obesity; lower partial pressure of arterial oxygen to fraction of inspired oxygen ratio; and higher urea level, white cell count, neutrophil count, and C-reactive protein, lactate dehydrogenase and ferritin levels, and high neutrophil to lymphocyte ratio. The overall survival rate for all hospital admissions was 86/116 (73%). In this early cohort, survival was similar in patients with HIV (n=18; 75%) compared with those without HIV (n=67; 75%) (p=1). Of the 74 patients admitted to the wards, 63 (85%) survived, whereas 22 of 42 (52%) admitted to the intensive care unit survived.
Patients with HIV infection represented a large proportion of all COVID-19 admissions. The presentation and outcome of patients with HIV did not differ significantly from those of patients without HIV.
Background An increased incidence of thromboembolic events in hospitalised COVID-19 patients has been demonstrated despite the use of low-molecular-weight heparin (LMWH). Antiplatelet therapy prior ...to admission and early in the disease course has been hypothesised to be protective against thrombosis.Objectives To describe the bleeding and thrombosis outcomes in hospitalised patients with confirmed COVID-19 receiving LMWH, with and without concomitant antiplatelet therapy. Secondary objectives were to explore predictors of bleeding and thrombosis outcomes, and dosing practices of antiplatelet therapy and LMWH.Methods We conducted a descriptive, cross-sectional study of bleeding and thrombosis outcomes at Tygerberg Academic Hospital, Cape Town, South Africa, during the first COVID-19 wave, in 808 hospitalised patients with confirmed COVID-19 receiving LMWH with and without concomitant antiplatelet therapy. Multivariate logistic regression analysis was performed if predictors were deemed statistically and clinically significant.Results Patients receiving both LMWH and antiplatelet therapy had similar bleeding outcomes compared with patients only receiving LMWH (odds ratio (OR) 1.5; 95% confidence interval (CI) 0.6 - 4.0). Patients receiving both LMWH and antiplatelet therapy had increased odds of developing thrombosis compared with patients only receiving LMWH (OR 4.8; 95% CI 2.1 - 10.7).Conclusion The bleeding risk in COVID-19 patients receiving both LMWH and antiplatelet therapy was not significantly increased. A potentially higher risk of thrombosis in patients receiving LMWH and antiplatelet therapy was observed. However, this could reflect confounding by indication. Randomised studies are required to further evaluate the use of antiplatelet therapy to treat hospitalised patients with COVID-19.
BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic placed an unprecedented strain on intensive care units (ICUs) in South Africa. Infection prevention and control (IPC) strategies were ...highlighted to minimise the risk to healthcare workers and for the protection of patients from contracting hospital-acquired infections (HAIs). During the third wave, our institution adopted a shift system to address severe burnout among ICU personnel. We noted an upstroke in the occurrence of HAIs, specifically carbapenem-resistant Enterobacterales (CRE) and multidrug-resistant (MDR) Acinetobacter baumannii OBJECTIVES: To report these outbreaks, compare the rate of CRE and A. baumannii infections with the first COVID-19 wave and to analyse its impact on patient outcomes METHOD: We retrospectively analysed data from a prospectively collected registry involving all adult patients with severe COVID-19 admitted to the dedicated COVID-19 ICU from May 2021 to September 2021. Information from the admission database, including the patients' demographics, comorbidities, laboratory results and length of ICU stay were extracted RESULTS: Ninety patients were admitted with severe COVID-19 during the third wave. There was an outbreak of both CRE (the majority Klebsiella pneumoniae) and A. baumannii. Furthermore, 18 patients cultured the same CRE organism, and 25 patients cultured the environmental organism A. baumannii. The HAI rate was significantly higher compared with the first wave published data: 59/90 (65.6%) v. 73/363 (20.1%, p<0.01). Patients with any HAI had a longer mean stay in ICU (10.1 days v. 6.7 days (p<0.01) and a higher mortality of 48/59 (81%) v. 19/31 (61%) (p=0.05 CONCLUSION: We observed a very significant rise in HAIs in the COVID-19 ICU during the third wave compared with the first, with almost three times as many patients developing HAIs. Unsurprisingly, it was associated with a longer mean stay in ICU and a higher mortality. The outbreak of both CRE and A. baumannii, and the fact that many patients cultured the same CRE organism and A. baumannii, strongly suggests that a critical breakdown in IPC measures had occurred
Background. Obesity is now well recognised as a risk factor for severe COVID‐19, but the true prevalence of obesity in hospitalised adults with COVID‐19 remains unclear because formal body mass ...indices (BMIs) are not routinely measured on admission.
Objectives. To describe the true prevalence of obesity measured by the BMI, and associated comorbidities, in patients hospitalised with severe COVID‐19, including people with HIV (PWH).
Methods. We conducted a point‐prevalence study of measured BMI in consecutive patients with severe COVID‐19 admitted to the medical COVID‐19 wards in a tertiary academic hospital in Cape Town, South Africa (SA). Patients were enrolled over a 2‐week period during the peak of the first COVID‐19 wave in SA.
Results. We were able to measure the BMI in 122 of the 146 patients admitted during the study period. The prevalence of HIV was 20% (n=24/122). Most of the participants were overweight or obese (n=104; 85%), and 84 (68.9%) met criteria for obesity. The mean (standard deviation) BMI was 33 (7.5), and 34.5 (9.1) in PWH. Of PWH, 83% (n=20/24) were overweight or obese and 75% (n=18) met criteria for obesity. Multimorbidity was present in 22 (92%) of PWH.
Conclusion. We found that most patients, including PWH, met criteria for being overweight or obese. The high prevalence of obesity in PWH and severe COVID‐19 reinforces the need for targeted management of non‐communicable diseases, including obesity, in PWH.
Background Lung cancer is the leading cause of cancer-related death globally and in South Africa. Historically, the majority of patients diagnosed with lung cancer are incurable at ...presentation.Objectives To assess the tumour, nodes, metastasis (TNM) staging of lung cancer in a centre with access to both positron emission tomography-computed tomography (PET-CT) and endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) using a structured diagnostic approach and to compare results with a historical cohort from 2009 from the same hospital.Methods A retrospective descriptive observational study was performed using the registry of a high-volume tertiary hospital’s weekly multidisciplinary thoracic oncology meeting (MDT). A structured diagnostic approach was used for staging purposes. All patients with a tissue diagnosis of primary lung cancer and adequate imaging (chest CT and/or PET-CT) who presented at the MDT during the period from 1 January - 31 December 2019 were included. Final staging and tissue diagnoses were documented and compared with a historical cohort from 2009 from the same institution.Results Adenocarcinoma was the most common subtype (38.8%; n=116). Less than a tenth of patients (6.3%; n=16/254) with non-small cell lung cancer had potentially curable lung cancer (stage IA to IIIA) at presentation, significantly less than the 2009 cohort (14.5%; n=25/173; p=0.007). The most common procedure administered on patients was transthoracic needle aspiration (37.54%; n=112), followed by conventional bronchoscopic needle aspiration or biopsy (20.4%; n=61), and EBUS-TBNA (17.1%; n=51/299). After PET-CT, 19/30 cases were upstaged including 9/18 from potentially resectable to unresectable. Two of these cases were down-staged to potentially resectable following EBUS-TBNA.Conclusions There was a significant decline in resectable and potentially curable lung cancer at presentation over a 10-year period. PET-CT and EBUS-TBNA improved the accuracy of non-small cell lung cancer staging among patients with resectable and potentially curable lung cancer but have exposed a higher stage profile.
