Evaluation of clinical, laboratory, radiographical and histopathological characteristics in patients with spinal tuberculosis in the context of HIV infection: An analysis of 52 patients from a South African tertiary hospital.

South Africa (SA) has the highest prevalence of people with tuberculosis (TB) and HIV coinfection globally. People living with HIV have an increased risk of TB infection, and are more likely to develop extrapulmonary TB. Approximately 10 - 20% of extrapulmonary TB accounts for skeletal TB, with spinal involvement in 50 - 60% of instances. Previous studies have shown highly heterogenic results regarding the effect of HIV status on clinical and laboratory characteristics in patients with spinal TB (STB). To describe the clinical, laboratory, radiographical and histopathological characteristics of patients diagnosed with STB stratified by HIV status. Data from patients who were treated for STB at the Division of Orthopaedic Surgery, Groote Schuur Hospital, SA, between 2013 and 2016 were analysed. We compared clinical, laboratory, radiographical and histopathological parameters of STB patients with HIV infection to those without HIV infection. To assess differences in means between the two groups, an independent samples t-test was used for normally distributed continuous data, and a χ2 test for categorical data. To assess correlations between continuous data groups, the Pearson correlation coefficient was used. We assessed 52 patients with STB (mean (standard deviation (SD) age 38 (15.2) years, range 17 - 80 years), of whom 55.8% were female, and 59.6% HIV infected. Five (9.6%) patients were identified with multidrug-resistant TB of the spine, with four (19.0%) in the HIV-infected cohort and one in the HIV-uninfected cohort (p=0.058). Significantly more STB patients without HIV infection presented with neurogenic symptoms (29%, p=0.029). The mean (SD) overall erythrocyte sedimentation rate was 69.3 (35.9) mm/h, with no significant difference between HIV-infected and HIV-uninfected patients (p=0.086). The rate of vertebral collapse was higher in the HIV-infected cohort (39% v. 67%, p=0.048). HIV-infected patients showed a higher count of involved vertebrae (mean 3.0 v. 3.85; p=0.034). There was no correlation between CD4 count and the number of involved vertebrae. The mean (SD) number of granulomata per low-power field was 10 (12.6), with no difference between the two cohorts. However, we found a positive correlation between granuloma count and CD4 cell count in HIV-infected STB patients (Pearson 0.503, p=0.02), with significantly higher formation of granulomata at a CD4 cell count >400 cells/μL (p=0.045). In our cohort, HIV-infected patients with STB were more likely to present with vertebral collapse, and more vertebrae on average were diseased compared with HIV-uninfected patients with STB. CD4 cell count may affect granuloma formation, and it seems that HIV infection has a negative effect on cellular immunoresponse in STB, which emphasises the need for early antiretroviral therapy initiation.

First-Line Antituberculosis Drug Challenge Reactions in Drug Reaction With Eosinophilia and Systemic Symptoms Syndrome in an HIV Endemic Setting

BackgroundIn high HIV prevalence settings, first line anti-tuberculosis drug (FLTD)-associated DRESS poses therapeutic challenges. Sequential and additive drug challenge (SADC) of FLTDs best identifies offending drug(s), avoids unnecessary exclusions, and optimises re-initiation of non-offending drugs. However, SADC-associated reaction complexities limit its utility. ObjectiveWe aimed to describe characteristics of FLTD-associated DRESS patients, their treatment-limiting SADC reactions and related outcomes. MethodsPatients hospitalized with FLTD-associated DRESS from 2013–2023 in a South African tertiary hospital and enrolled (retrospectively or prospectively) in an existing registry were eligible. ResultsSADC was undertaken in 41 patients. Overall, 47 classifiable reactions occurred, 34/47(72%) in 29/41(71%) patients, were treatment-limiting and 12/41(29%) reinitiated FLTDs uneventfully. Fifteen single and eight multiple drug-reactors were identified. Rifampicin, in 13/23(57%) reactors was the commonest individual offender. Ethambutol was most frequently involved in multiple drug-reactors. Median(IQR) time to a detectable reaction was 24(12-120) hours, 6/34(18%) being immediate (<6hours). Itch (65%), eosinophilia (56%), fever (41%), atypical lymphocytosis (41%), rash (38%), transaminitis (32%) and facial oedema (18%), singly or in combination were commonest features. Three reactions, one epidermal necrolysis and two liver derangements, were CTCAE grade 4 (life-threatening) events. No predictors of multiple drug-reactivity were identified, but multiple reactors were hospitalised significantly longer, 125(100-134) versus 60(45-80) days. ConclusionsSADC optimises FLTD reinitiation. However, timing, clinical presentation and severity of SADC-associated reactions following FLTD-associated DRESS is markedly heterogenous. Additionally, multiple drug-reactors are a complex group requiring longer hospitalisation, and without routine biomarkers to differentiate true multiple drug hypersensitivity from non-specific flare-ups and guide long-term drug avoidance strategies.

Hypervirulent Klebsiella pneumoniae in a South African tertiary hospital—Clinical profile, genetic determinants, and virulence in Caenorhabditis elegans

IntroductionA distinct strain of Klebsiella pneumoniae (K. pneumoniae) referred to as hypervirulent (hvKp) is associated with invasive infections such as pyogenic liver abscess in young and healthy individuals. In South Africa, limited information about the prevalence and virulence of this hvKp strain is available. The aim of this study was to determine the prevalence of hvKp and virulence-associated factors in K. pneumoniae isolates from one of the largest tertiary hospitals in a South African province.MethodsA total of 74 K. pneumoniae isolates were received from Pelonomi Tertiary Hospital National Health Laboratory Service (NHLS), Bloemfontein. Virulence-associated genes (rmpA, capsule serotype K1/K2, iroB and irp2) were screened using Polymerase Chain Reaction (PCR). The iutA (aerobactin transporter) gene was used as a primary biomarker of hvKp. The extracted DNAs were sequenced using the next-generation sequencing pipeline and the curated sequences were used for phylogeny analyses using appropriate bioinformatic tools. The virulence of hvKp vs. classical Klebsiella pneumoniae (cKp) was investigated using the Caenorhabditis elegans nematode model.ResultsNine (12.2%) isolates were identified as hvKp. Moreover, hvKp was significantly (p &amp;lt; 0.05) more virulent in vivo in Caenorhabditis elegans relative to cKp. The virulence-associated genes [rmpA, iroB, hypermucoviscous phenotype (hmv) phenotype and capsule K1/K2] were significantly (p &amp;lt; 0.05) associated with hvKp. A homology search of the curated sequences revealed a high percentage of identity between 99.8 and 100% with other homologous iutA gene sequences of other hvKp in the GenBank.ConclusionFindings from this study confirm the presence of hvKp in a large tertiary hospital in central South Africa. However, the low prevalence and mild to moderate clinical presentation of infected patients suggest a marginal threat to public health. Further studies in different settings are required to establish the true potential impact of hvKp in developing countries.

A five-year retrospective antibiogram review in the paediatric burns unit at a tertiary South African Hospital

BackgroundThere is a global concern regarding increasing colonization and/or infection of paediatric burns patients with multi-drug-resistant organisms, especially in Africa. Surveillance of antimicrobial resistant patterns enables clinicians to opt for the most appropriate empiric antimicrobial agent according to the unit’s susceptibility profile. ObjectiveThis study sought to compile unit-specific antibiograms comparing the organism prevalence and their antimicrobial resistance trends in the paediatric burns unit, Chris Hani Baragwanath Academic Hospital (CHBAH) from January 2015 to December 2019. MethodsA retrospective, laboratory-based review was conducted of bacterial and fungal isolates including antimicrobial susceptibility testing (AST) data from blood cultures and tissue samples. Enterobacterales, non-fermenters, gram-positive organisms, and yeasts were analysed as a percentage of total positive blood cultures comparing 2015–2017 to 2018–2019 data. Analysis of antimicrobial resistance trends was performed for extended-spectrum beta-lactamases (ESBLs), carbapenem-resistant Enterobacterales (CRE), extensively-drug-resistant (XDR) Acinetobacter baumannii, and meticillin-resistant Staphylococcus aureus (MRSA) for the years 2015, 2017, and 2019. ResultsA total of 1243 blood culture isolates were studied with A.baumannii (208/1243;17 %), coagulase negative staphylococci (141/1243; 11 %) and Candida auris (53/1243; 4 %) representing the predominant gram-negative bacteria, gram-positive bacteria, and yeast, respectively. A significant decrease in ESBLs (p = 0.00) was noted with a rise in CREs (p = 0.00) during the study period. Majority of the A. baumannii were XDR (≥77 %) despite an appreciable decrease. A notable decrease in MRSA (p = 0.00) isolates was observed. Pseudomonas aeruginosa (72/275; 26 %) was the leading organism recovered from a total of 275 tissue isolates. ConclusionThe results of this study encourage review of the current antimicrobial choices in the unit for empiric antibacterial cover. Due to the low numbers of yeasts, we cannot comment on the institution of early antifungal strategies. We support reinforced infection prevention and control practices as well as antimicrobial stewardship initiatives.

The effect of the SARS-CoV2 pandemic and lockdown on non-Covid ICU admissions: Experience from a South African tertiary hospital.

Future pandemic planning involves analysing past experiences. We compared intensive care unit (ICU) admissions during the SARS-CoV-2 pandemic (2020) with the preceding year. To assess the SARS-CoV-2 pandemic's effect on ICU admissions in a tertiary hospital, examining differences in patient characteristics, organ support requirements, reason for admission, mortality rates and length of ICU stay. This retrospective cohort study compared ICU patient data at a tertiary hospital during the SARS-CoV-2 pandemic (26 March 2020 to 20 September 2020) with the same period in 2019. Patient admissions (p=0.39) and severity of illness (p=0.27 adults; p=0.92 paediatrics) showed no differences across the study period. Similarly, no differences were observed for underlying chronic conditions between the two years. Adult trauma admissions significantly declined, specifically those related to road traffic accidents (RR 0.63). Admissions for acute infectious conditions, including respiratory infections, sepsis, urosepsis, septic arthritis and gastroenteritis significantly declined in both adults (RR 0.50) and paediatric admissions (RR 0.25). During the lockdown period, the length of stay (LOS) decreased for adults, but mortality rates remained unchanged across the study period. The paediatric mortality rate decreased during the lockdown period (p=0.004). There was no reduction in SARS-CoV-2-negative ICU admissions during the 2020 lockdown period compared with the preceding year, likely due to chronic resource limitations. We found a decrease in acute trauma and acute infectious illness admissions, while acute surgical emergency admissions increased. These findings suggest that lockdown orders may have affected admission patterns, aiding in future pandemic planning. The study highlights the chronic shortage of critical care resources in South Africa and aids with future pandemic preparedness and planning in a resource limited setting.

Perioperative care to patients living with HIV by theatre nurses at a South African tertiary hospital

Background Human Immunodeficiency Virus (HIV) is one of the leading health challenges worldwide that influences the provision of quality patient care. Stigma and discrimination around this condition and the health care needs affect the health care provision. This study aimed to gain an in-depth understanding of theatre nurses’ experiences in providing perioperative care to patients living with HIV at a tertiary hospital in South Africa. Methods This study was conducted at a tertiary hospital in Tshwane district, South Africa. The study was underpinned by an interpretative phenomenological analysis design. Data were collected from 10 criterion purposively selected theatre nurses using in-depth individual interviews. Data were thematically analyzed and guided by an interpretive phenomenological analysis framework for data analysis. Results The study revealed that theatre nurses work in an under-resourced environment. The resources highlighted are human, materials, including personal protective equipment and life support. The situation negatively affects the perioperative care of HIV-positive patients, who are always prone to perioperative complications, such as profuse bleeding, and even death. The situation increases the occupational risk to the nurses. Conclusions The researchers proposed several recommendations targeted at improving the resources needed by theatre nurses when caring for people living with HIV perioperatively at South African tertiary hospitals. Findings will add to the body of knowledge of the Nursing profession about offering perioperative care to persons living with HIV.

Closed intra-articular tibial plafond fractures managed with circular external fixation: clinical outcomes at a South African tertiary hospital

BACKGROUND: Tibial plafond fractures are complex injuries involving the distal tibiotalar cartilage, and the mechanism of injury is usually high energy. The approach to management is complicated by soft tissue compromise and the lack of consensus regarding a superior fixation method. Complications result in long-term functional and social disability. This study aimed to assess the short-term outcomes and complications in patients with closed tibial plafond fractures surgically managed with circular external fixation (CEF). METHODS: We retrospectively reviewed a series of patients diagnosed with closed tibial plafond fractures in a tertiary hospital in South Africa between January 2016 and December 2019. We identified 35 patients who underwent surgical management with CEF. We assessed files for inpatient notes, outpatient follow-up notes, and radiographic analysis. Clinical data collected included demographics, comorbidities, postoperative complications, and the need for reoperation. Radiological data included reduction, fracture union, equinus, and post-traumatic osteoarthritis on X-rays at the final follow-up. RESULTS: The cohort was predominantly male (n = 29 of 35, 83%), with a median age of 38 years (interquartile range [IQR] 32-46 years). The mechanism of injury was found to be high-energy trauma in 23 patients (66%). The median follow-up period was 28 weeks (IQR 24-43 weeks). Ninety-one per cent of patients achieved fracture union (n = 32 of 35) at a median of 19 weeks (IQR 17-24 weeks). High-energy mechanism of injury showed a statistically significant increase in time to union for patients (p = 0.034). Radiological reduction was acceptable to good in 69% of patients. The superficial sepsis rate was 29%, with one patient (3%) developing deep sepsis. Diabetes mellitus was seen as a significant risk factor. Eighty-five per cent of patients (n = 28 of 35) developed post-traumatic arthritis of the ankle joint. CONCLUSION: Our study showed a high rate of fracture union and acceptable reduction with this treatment method. Ankle radiological outcomes are affected, with patients developing equinus deformities and post-traumatic ankle arthritis. Further prospective studies are required to determine longterm outcomes. Level of evidence: Level 4

The prevalence of malnutrition in patients requiring total joint arthroplasty in a South African tertiary hospital

BACKGROUND: With the global increase in total joint arthroplasty (TJA), including total hip arthroplasty (THA) and total knee arthroplasty (TKA), there has been a parallel increase in complications. Optimising modifiable risk factors preoperatively can limit the impact of postoperative complications. Malnutrition is one such modifiable risk factor. With limited evidence regarding malnutrition in patients undergoing TJA in South Africa, we sought to determine the prevalence of malnutrition in patients presenting for TJA at a single institution in South Africa. The objectives of the study were to determine the prevalence of malnutrition among patients presenting to a South African tertiary institution for TJA, and to determine the relationship between malnutrition and comorbidities and demographics. METHODS: We performed a retrospective review of 414 patients presenting for the first time to an arthroplasty unit over a 15-month period. Patients presenting for primary TJA, revision TJA, and patients presenting for fractured neck of femur (FNF) were included. Serological testing of albumin &lt; 35 g/L and/or low transferrin (&lt; 2 g/L) were used to diagnose malnutrition. The relationship between demographic data, comorbidities, presentation for type of TJA, and malnutrition were evaluated. RESULTS: In total, 414 patients were included. The mean age was 61.1 ± 10.95 years, and 75% (n = 311) were female. Patients presenting for elective TJA composed 88% (n = 366) of the study population, with 12% (n = 48) patients referred for FNF. The mean BMI was 33.3 ± 8.15 kg/m2. The prevalence of malnutrition was 11% (n = 47). Patients presenting for elective TJA had a prevalence of malnutrition of 6% (n = 23), compared to patients presenting with FNF of 50% (n = 24). Hypertension (45%, n = 18), HIV (19%, n = 9), diabetes mellitus (18%, n = 7), chronic kidney disease (18%, n = 7) and inflammatory arthritis (15%, n = 6) were the most common comorbidities in patients with malnutrition. Patients with malnutrition had a higher mean age (p = 0.024), lower mean haemoglobin (p &lt; 0.001), lower mean BMI (p = 0.047) and a lower CD4 in HIV-positive patients (p = 0.031). CONCLUSION: The prevalence of malnutrition of 11% in this cohort of South African patients presenting for TJA is similar to published results from developed countries. There is a need for high-powered prospective studies to determine the viability of routine preoperative nutritional testing or limit testing of high-risk patients. Level of evidence: Level 4

Spectrum of offending drugs and cutaneous adverse drug reactions requiring hospitalisation in a tertiary South African hospital in TB/HIV endemic setting.

Cutaneous immune-mediated adverse drug reactions are more prevalent in people with human immunodeficiency virus (PWH). Severe cutaneous adverse drug reactions (SCAR) are a life-threatening subset of cutaneous adverse drug reactions (CADRs) and a significant public health issue in settings endemic for human immunodeficiency virus and tuberculosis. However, limited data are available on CADR requiring hospitalisation in African settings. The aim of this study is to describe the epidemiology, offending drugs and outcomes of CADRs requiring admission to a South African tertiary dermatology service. Retrospective folder review was conducted on all CADRs requiring hospitalisation at Nelson Mandela Academic Hospital in Mthatha, Eastern Cape, South Africa between 30 July 2015 and 15 December 2022. This data was compared to prospective inclusion of CADR admissions between 03 March 2021 and 09 April 2024 as part of the Immune-Mediated Adverse Drug Reactions (IMARI) Registry and Biorepository and AFRISCAR consortium. Where possible, phenotype and drug causality assessment was performed through RegiSCAR, or Naranjo and/or ALDEN scoring respectively. CADR admissions included 122 cases: 89 and 33 in the retrospective and prospective cohorts respectively. The commonest SCAR phenotype was Stevens-Johnson syndrome/toxic epidermal necrolysis (SJS/TEN) at 59.8% (73/122), although other validated SCAR phenotypes included drug reaction with eosinophilia and systemic symptoms (DRESS), acute generalized exanthematous pustulosis (AGEP) and generalized fixed bullous drug eruption (GBFDE). Cutaneous presentations included typical and atypical SCAR features against a background Fitzpatrick skin tones of type IV and above. Amongst the retrospective cohort 16.9% (15/89) of phenotypes were unclassifiable due to lack of photographs. The overall median (IQR) age was 38 (25-50) years, 50.8% (62/122) were male and 60.7% (74/122) were PWH [median (IQR) CD4T-cell count of 267 (76-470) cells/mm3]. The commonest offending drugs included cotrimoxazole in 24.6% (30/122); and anti-retroviral therapy (ART) in 13.9% (17/122). No offending drug could be identified in 24.7% (22/89) of the retrospective cohort. The median (IQR) length of hospital stay for validated SCAR was 13 (8-21) days for the retrospective cohort and 19 (13-28) days for the prospective cohort (p = 0.03). The median (IQR) length of hospital stay for non-SCAR was 9 (5-13) days for the retrospective cohort and 11 (9-16) days for the prospective cohort. Typical and atypical presentations of SCAR were represented in this vulnerable South African cohort of predominantly PWH. SJS/TEN was the commonest phenotype, and cotrimoxazole the most frequent offending drug. This data emphasises the need for prospective data collection across a diverse African population for valid SCAR phenotyping and drug causality assessment.

Prevalence and factors associated with burnout among junior medical doctors at a South African tertiary public sector hospital.

burnout is a syndrome characterized by emotional exhaustion, depersonalization and emotional exhaustion that occurs due to exposure to stressful conditions over a long period. It can lead to poor job performance, apathy, and lack of productivity. This study looks at the prevalence of burnout in medical interns in a tertiary hospital in South Africa and the factors that may contribute to burnout. an analytical cross-sectional study was conducted. Medical interns working in Chris Hani Baragwanath Hospital in 2019 were invited to participate. The participants filled questionnaire that had demographic information, the Maslach Burnout Inventory Scale, a scale to rate the rotations that they believed contributed towards their burnout and factors they think contributed towards their burnout. Our data was analyzed using Stata. out of a possible 165 potential participants, 101 medical interns enrolled. 95% of the participants reported burnout. Statistically significant factors contributing towards burnout were lack of resources and poor relations with support staff and senior staff. The medical rotation that was reported by the participants to contribute most towards their burnout was internal medicine. burnout in this population of medical interns is alarmingly high. Higher than reported in similar studies in South Africa and internationally.

Changing character and waning impact of COVID-19 at a tertiary centre in Cape Town, South Africa.

The emergence of genetic variants of SARS-CoV-2 was associated with changing epidemiological characteristics throughout coronavirus disease 2019 (COVID-19) pandemic in population-based studies. Individual-level data on the clinical characteristics of infection with different SARS-CoV-2 variants in African countries is less well documented. To describe the evolving clinical differences observed with the various SARS-CoV-2 variants of concern and compare the Omicron-driven wave in infections to the previous Delta-driven wave. We performed a retrospective observational cohort study among patients admitted to a South African referral hospital with COVID-19 pneumonia. Patients were stratified by epidemiological wave period, and in a subset, the variants associated with each wave were confirmed by genomic sequencing. Outcomes were analysed by Cox proportional hazard models. We included 1689 patients were included, representing infection waves driven predominantly by ancestral, Beta, Delta and Omicron BA1/BA2 & BA4/BA5 variants. Crude 28-day mortality was 25.8% (34/133) in the Omicron wave period versus 37.1% (138/374) in the Delta wave period (hazard ratio [HR] 0.68 [95% CI 0.47-1.00] p = 0.049); this effect persisted after adjustment for age, gender, HIV status and presence of cardiovascular disease (adjusted HR [aHR] 0.43 [95% CI 0.28-0.67] p < 0.001). Hospital-wide SARS-CoV-2 admissions and deaths were highest during the Delta wave period, with a decoupling of SARS-CoV-2 deaths and overall deaths thereafter. There was lower in-hospital mortality during Omicron-driven waves compared with the prior Delta wave, despite patients admitted during the Omicron wave being at higher risk. This study summarises clinical characteristics associated with SARS-CoV-2 variants during the COVID-19 pandemic at a South African tertiary hospital, demonstrating a waning impact of COVID-19 on healthcare services over time despite epidemic waves driven by new variants. Findings suggest the absence of increasing virulence from later variants and protection from population and individual-level immunity.

Screening practices, efficacy, safety and adherence to biologic therapies in a South African tertiary hospital

IntroductionThe high cost and concern of adverse events, particularly infections, limit the use of biologic therapies. We undertook this retrospective study to document their use for immune-mediated diseases, and explore the screening practices, efficacy, safety, and adherence to bDMARDs in a tertiary hospital.MethodsA folder review of all adult and paediatric patients treated for IMDs with bDMARDs. Changes in disease activity were measured by disease-specific tools at 6, 12, 24-months and at the last available visit, and patient adherence to bDMARDs was explored by folder and pharmacy record review.ResultsWe studied 120 folders; 145 bDMARDs were prescribed (23 patients switched bDMARD). BDMARDs prescribed included tumour necrosis factor inhibitors (TNFi) (76), rituximab (54), tocilizumab (9), anakinra (3), abatacept (1), ustekinumab (1) and tofacitinib (1). The vast majority of patients had an excellent response and achieved low disease activity or remission at their last available visit. Adverse events included severe infection (9) including two cases of tuberculosis (TB), mild skin reaction (6) and severe infusion reactions (4). Therapy was discontinued in 13 patients, most commonly due to infection (5), lack of response (4), or poor adherence (3). Poor adherence was noted in 8/120 (6.7%). Complete latent TB infection screening was performed in only 35 patients (29.2%). Screening for Hepatitis B, C and HIV was performed in 28 (23.3%), 62 (51.7%) and 61 (50.8%) patients, respectively. Only 20.8% and 20.0% received the influenza and pneumococcal vaccination.Discussion and conclusionBiologic therapy was effective, and the most important serious adverse effect was infection, which was significantly associated with TNFi therapy. Vaccination and screening for TB, viral hepatitis and HIV was suboptimal. Of concern, poor adherence to bDMARDs was frequently encountered.

Factors influencing outcome in patients with perforated peptic ulcer disease at a South African tertiary hospital.

Perforated peptic ulcer (PPU) is associated with significant morbidity and mortality, particularly in low to middle income countries. This study aimed to scrutinise the clinical course of patients diagnosed with PPU and identify modifiable factors to improve outcomes. A retrospective review of the hybrid electronic medical record (HEMR) database at Grey's Hospital was performed. All patients diagnosed with PPU between January 2013 and December 2020 were entered into the study. The variables collected include age, ethnicity, comorbid profile, Boey score, type of surgery performed and complications. These factors were analysed to determine the factors responsible for morbidity and mortality. One hundred and ninety four patients were diagnosed with PPU during the study period. Six patients were treated non-operatively, all of whom survived. In the surgically treated group, omental patch repair was performed in 159 (84.5%) patients, and primary closure in 26 (13.8%) patients. The leak rate was 32% in the cohort that underwent relaparotomy and the overall mortality was 14%. There was no significant relationship between the type of repair performed and outcome. All patients had a Boey score of 1 or more. The following factors were found to increase the probability of in-hospital mortality: age > 40 years (OR: 8.49, 95% CI 2.46-29.29 p < 0.01), female gender (OR: 2.509, CI 0.98-6.37, p = 0.048), need for relaparotomy (OR: 0.398, CI 0.17-0.91, p = 0.027) and Boey score > 1 (OR: 46.437, CI 6.13-350.28, p < 0.01). A Boey score > 1 was the only variable that increased the likelihood of finding a leaking repair at relaparotomy (p < 0.01). The Boey score was a significant predictor of mortality and leak rate in our patients with PPU. Adding age as a variable may improve the ability to predict mortality in our setting, while the impact of gender and ethnicity needs further investigation.

MICROBIAL CONTAMINATION OF CELLPHONES OF HEALTHCARE WORKERS IN THE ORTHOPAEDIC DEPARTMENT AT A TERTIARY INSTITUTE IN GAUTENG

The role that fomites have to play in surgical site infection (SSI) and periprostheitic joint infection (PJI) has been observed and researched in the past. However the role that cellphones play in the transfer of microorganisms from hands to surgical sites and the indiscriminate use of cellphones within the Orthopaedics, could increase the risk of infection. This study aimed to measure the contamination of cellphones of health care workers (HCW's) in a South African tertiary hospital. Secondarily was to investigate the cellphone hygiene behaviour of HCW's.A prospective cross-sectional study was conducted in June 2022. Samples were taken from the the participant's cellphones under an aseptic technique and sent for microbiology. The participants also filled out a questionnaire on cellphone behaviour. The inclusion criteria was orthopaedic HCW's working in the institution; This included nurses and doctors in the orthopaedic theatres and main orthopaedic wards.Sixty-two participants were included; 54 from Orthopaedics and 7 from Anaesthesia. From the samples, 71% grew pathogens while 30,64% grew two or more colonies. This is slightly lower than other studies which showed contamination up to 100%. Micro-organisms cultured included Staphylococcus species; S.Epidermidis, Methycillin sensitive S.aureas; and E.Coli. Cellphone hygiene behaviour was also better than most other studies in terms of frequency of cleaning the devices and hand hygiene around cellphone usage. This which may be a contributing factor to the lower micro-organism contamination.This study should be the first of many as we have identified that there are indeed pathogens on cellphones transferable to patients; causing sepsis. Though cellphones have become vital in patients management in the hospital setting, factors such as improvement in cellphone hygiene through education and frequent cleaning of cellphones will aid in disabling the negative impact of cellphones in the orthopaedic environment.

The Effect on Theatre Nurses for Rendering Perioperative Care to Patients Living with HIV in a South African Tertiary Hospital.

The study aimed to gain an in-depth understanding of how theatre nurses are being affected when they render perioperative care to patients living with HIV in a South African tertiary hospital. There is a scarcity of studies that focus solely on the wellbeing of theatre nurses who render perioperative care to HIV patient due to the ramifications of the nurses' fear of contracting HIV. Patients living with HIV often receive substandard care. To establish how theatre nurses are being impacted when rendering perioperative care to patient living with HIV, the study followed a qualitative approach using an interpretative phenomenological analysis design. Data were collected through in-depth individual interviews from ten theatre nurses who were purposively selected according to specific criteria. They voluntarily agreed to participate. An interpretive phenomenological analysis framework was used to analyse the data. Two main themes emerged from the data analysis, namely, the negative effect on nurses' wellbeing and the impact that it had on them professionally. The study revealed that the perioperative care of patients living with HIV had a negative impact on physical, mental, and social wellbeing of theatre nurses. Their compromised wellbeing in turn led to poor patient care, which put nurses at risk of losing their jobs and even potentially having to face litigation. The study further indicated that nurses did not receive psychological support from the management which further affected their health and professional performance. The study proposes that theatre nurses rendering perioperative care to people living with HIV should receive proper training and support; staff shortages should also be addressed. There is also an urgent need for appropriate and sufficient protective equipment. Such changes will be essential in order to mitigate the negative impact that their jobs have on their wellbeing and on them in their professional capacity.

Clinical profile and outcomes of young patients treated with implantable cardioverter defibrillators at a South African tertiary hospital: a review of two decades of implantable cardioverter defibrillator implantation and follow up.

In young patients without atherosclerotic coronary artery disease, the aetiology of sudden cardiac death (SCD) has been described in Europe and North America. However, there are important regional variations and there are limited data on the aetiology and outcome of SCD in South Africa. The objective of this study was to determine the profile and outcomes of young patients treated with implantable cardioverter defibrillators (ICDs) at a South African tertiary hospital. This study was designed as a retrospective review of patients aged 35 years or younger implanted with ICDs at Groote Schuur Hospital. During the study period, 38 patients younger than 35 years were implanted with ICDs. The mean (standard deviation) age at ICD implantation was 25.1 (7.6) years and 63.2% were male. A secondary-prevention ICD was implanted in 57.9% of the patient population, and primary prevention in the remaining 42.1%. Patients with secondary-prevention ICDs presented with ventricular tachycardia (59.1%), ventricular fibrillation (31.8%) and receipt of cardiopulmonary resuscitation but no recorded electrocardiograms (9.1%). Arrhythmogenic right ventricular cardiomyopathy (ARVC) was the leading cause of SCD in the secondary-prevention patient population (36.4%). Idiopathic dilated cardiomyopathy accounted for 50% of the primary-prevention patient population. After a median (interquartile range) follow up 32 (14-90) months, 7.9% died and 5.2% received a heart transplant; 42.1% of the study population received appropriate ICD shock therapies and 18.4% received inappropriate shock therapies. In this single-centre study from South Africa, ARVC and repaired congenital heart disease were the leading causes of SCD in patients younger than 35 years treated with secondary-prevention ICDs. Primary-prevention ICDs were frequently implanted for idiopathic dilated cardiomyopathy.

Diffuse alveolar haemorrhage in children hospitalised in a tertiary‑level hospital: A retrospective descriptive study.

Diffuse alveolar haemorrhage (DAH) is considered a rare condition in children. There is no consensus on the management of DAH syndromes in Africa or other low- and middle-income countries. In this brief report, the clinical characteristics, management and outcomes of children treated for DAH in the Chris Hani Baragwanath Academic Hospital paediatric pulmonology unit in Johannesburg, South Africa are described. Fifteen children were included in this case series, of whom 11 (73.3%) presented with severe microcytic anaemia. Of the 11 children who had bronchoalveolar lavage, 9 (81.8%; 60.0% of the total) had haemosiderin-laden macrophages on microscopy. Only 5 children had a lung biopsy, of whom 3 (60.0%) had capillaritis. All the children were started on oral prednisone at presentation, and 11 (73.3%) received additional complementary treatment. Nine children (60.0%) had normal haemoglobin levels 1 year after initiation of treatment. Our series supports previous reports that DAH is uncommon in children. A large proportion of our patients responded well to treatment despite some resource limitations. The study provides additional data on children presenting with diffuse alveolar haemorrhage in a South African tertiary hospital. There is a need for South African pulmonologists to come together and conduct a national audit of these patients in different hospitals to determine the incidence in our country, as well as to inform a management plan in the presence or absence of specialised tests.
