RESUMO

BACKGROUND: Sinus venosus atrial septal defect (SVASD) is a rare congenital cardiac anomaly comprising 5% to 10% of all atrial septal defects. Although surgical closure is the standard treatment for SVASD, data on outcomes have been confined to small cohorts. Thus, we conducted a systematic review of the outcomes of SVASD repair. METHODS AND RESULTS: The primary outcome was death. Secondary outcomes encompassed atrial fibrillation, sinus node dysfunction, pacemaker insertion, cerebrovascular accident, reoperation, residual septal defect, superior vena cava obstruction, and reimplanted pulmonary vein obstruction. Pooled incidences of outcomes were calculated using a random-effects model. Forty studies involving 1320 patients who underwent SVASD repair were included. The majority were male patients (55.4%), with 88.0% presenting with associated anomalous pulmonary venous connection. The weighted mean age was 18.6±12.5 years, and the overall weighted mean follow-up period was 8.6±10.4 years. The in-hospital mortality rate was 0.24%, with a 30-day mortality rate of 0.5% reported in 780 patients. Incidences of atrial fibrillation, sinus node dysfunction, pacemaker insertion, and cerebrovascular accident over the long-term follow-up were 3.3% (2.18%-4.93%), 6.5% (5.09%-8.2%), 2.23% (1.34%-3.57%), and 2.03% (0.89%-2.46%) respectively. Reoperation occurred in 1.36% (0.68%-2.42%) of surgeries, residual septal defect in 1.34% (0.69%-2.42%), superior vena cava obstruction in 1.76% (1.02%-2.9%), and reimplanted pulmonary vein obstruction in 1.4% (0.7%-2.49%). CONCLUSIONS: This is the first comprehensive analysis of outcomes following surgical repair of SVASD. The findings affirm the safety and effectiveness of surgery, establishing a reference point for evaluating emerging transcatheter therapies. Safety and efficacy profiles comparable to surgical repair are essential for widespread adoption of transcatheter treatments.

RESUMO

We report a diagnostically challenging case of a SMARCA4-deficient undifferentiated tumour to emphasize its potential to mimic other malignant tumours on histology, especially in small biopsies and where rhabdoid morphology is lacking. A 48-year-old man, who was known for chronic obstructive pulmonary disease and polysubstance use, presented with dyspnoea and an anterior mediastinal mass that had grown rapidly over a seven-month period. The rapid growth and location in the anterior mediastinum raised clinical suspicion for lymphoma or a germ cell tumour. Microscopic examination of a transthoracic, ultrasound-guided, core needle biopsy revealed relatively uniform, malignant epithelioid cells with clear cytoplasm, but lacking any rhabdoid features. Tumour necrosis was prominent. The immunohistochemistry panel was negative for lymphoma markers, but positive for SALL4 (a marker typically associated with germ cell tumours), CD34, EMA, and HepPar1, while expression of SMARCA4 and claudin-4 was entirely lost. Only focal cytokeratin expression was demonstrated. SMARCB1 (INI1) expression was retained. The diagnosis of SMARCA4-DUT was made based on these findings. Unfortunately, the tumour was already at an advanced stage at diagnosis (stage IVA) and the patient had a poor performance status. He was treated with palliative radiotherapy with no significant improvement in performance status and passed away 3 months after diagnosis. The case highlights the importance of considering SMARCA4-DUT in the differential diagnosis of an undifferentiated, rapidly growing thoracic tumour and the potential for misdiagnosis on a small tissue sample, particularly as rhabdoid morphology may be absent.

RESUMO

Objectives: The aim of this study was to describe the pattern of admissions during the fourth wave of COVID-19 in order to inform future public health policies. Methods: This was a retrospective descriptive study of an early cohort of all adult patients with SARS-CoV-2 infection admitted to a tertiary hospital in Cape Town, South Africa, at the start of the country's fourth wave. This was compared with an early cohort from the first wave at the same institution. Results: In total, 121 SARS-CoV-2-positive admissions from the fourth wave were included. Thirty-one (25.6%) patients had COVID-19 pneumonia, while 90 (74.4%) had incidental SARS-CoV-2 infection. (In the first wave all 116 patients had COVID-19 pneumonia.) Thirty-two (26.4%) patients self-reported complete or partial COVID-19 vaccination, of whom 12 (37.5%) were admitted with COVID-19 pneumonia. Compared with the first wave, there were fewer intensive- or high-care admissions (18/121 [14.9%] vs 42/116 [36.2%]; p < 0.001) and mortality was lower (12/121 [9.9%] vs 31/116 [26.7%]; p = 0.001). Conclusion: Admissions to the COVID-19 wards during the fourth wave primarily included patients with incidental SARS-CoV-2 infection. There was a reduction in the need for critical care and in-hospital mortality. This changing epidemiology of COVID-19 admissions may be attributed to a combination of natural and/or vaccination-acquired immunity.

RESUMO

BACKGROUND: Over 130 million people have been diagnosed with Coronavirus disease 2019 (COVID-19), and more than one million fatalities have been reported worldwide. South Africa is unique in having a quadruple disease burden of type 2 diabetes, hypertension, human immunodeficiency virus (HIV) and tuberculosis, making COVID-19-related mortality of particular interest in the country. The aim of this study was to investigate the clinical characteristics and associated mortality of COVID-19 patients admitted to an intensive care unit (ICU) in a South African setting. METHODS AND FINDINGS: We performed a prospective observational study of patients with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection admitted to the ICU of a South African tertiary hospital in Cape Town. The mortality and discharge rates were the primary outcomes. Demographic, clinical and laboratory data were analysed, and multivariable robust Poisson regression model was used to identify risk factors for mortality. Furthermore, Cox proportional hazards regression model was performed to assess the association between time to death and the predictor variables. Factors associated with death (time to death) at p-value < 0.05 were considered statistically significant. Of the 402 patients admitted to the ICU, 250 (62%) died, and another 12 (3%) died in the hospital after being discharged from the ICU. The median age of the study population was 54.1 years (IQR: 46.0-61.6). The mortality rate among those who were intubated was significantly higher at 201/221 (91%). After adjusting for confounding, multivariable robust Poisson regression analysis revealed that age more than 48 years, requiring invasive mechanical ventilation, HIV status, procalcitonin (PCT), Troponin T, Aspartate Aminotransferase (AST), and a low pH on admission all significantly predicted mortality. Three main risk factors predictive of mortality were identified in the analysis using Cox regression Cox proportional hazards regression model. HIV positive status, myalgia, and intubated in the ICU were identified as independent prognostic factors. CONCLUSIONS: In this study, the mortality rate in COVID-19 patients admitted to the ICU was high. Older age, the need for invasive mechanical ventilation, HIV status, and metabolic acidosis were found to be significant predictors of mortality in patients admitted to the ICU.

RESUMO

BACKGROUND: There is still a paucity of evidence on the outcomes of coronavirus disease 2019 (COVID-19) among people living with human immunodeficiency virus (PWH) and those co-infected with tuberculosis (TB), particularly in areas where these conditions are common. We describe the clinical features, laboratory findings and outcome of hospitalised PWH and human immunodeficiency virus (HIV)-uninfected COVID-19 patients as well as those co-infected with tuberculosis (TB). METHODS: We conducted a multicentre cohort study across three hospitals in Cape Town, South Africa. All adults requiring hospitalisation with confirmed COVID-19 pneumonia from March to July 2020 were analysed. RESULTS: PWH comprised 270 (19%) of 1434 admissions. There were 47 patients with active tuberculosis (3.3%), of whom 29 (62%) were PWH. Three-hundred and seventy-three patients (26%) died. The mortality in PWH (n = 71, 26%) and HIV-uninfected patients (n = 296, 25%) was comparable. In patients with TB, PWH had a higher mortality than HIV-uninfected patients (n = 11, 38% vs n = 3, 20%; p = 0.001). In multivariable survival analysis a higher risk of death was associated with older age (Adjusted Hazard Ratio (AHR) 1.03 95%CI 1.02-1.03, p < 0.001), male sex (AHR1.38 (95%CI 1.12-1.72, p = 0.003) and being "overweight or obese" (AHR 1.30 95%CI 1.03-1.61 p = 0.024). HIV (AHR 1.28 95%CI 0.95-1.72, p 0.11) and active TB (AHR 1.50 95%CI 0.84-2.67, p = 0.17) were not independently associated with increased risk of COVID-19 death. Risk factors for inpatient mortality in PWH included CD4 cell count < 200 cells/mm3, higher admission oxygen requirements, absolute white cell counts, neutrophil/lymphocyte ratios, C-reactive protein, and creatinine levels. CONCLUSION: In a population with high prevalence of HIV and TB, being overweight/obese was associated with increased risk of mortality in COVID-19 hospital admissions, emphasising the need for public health interventions in this patient population.

RESUMO

Early in the coronavirus disease 2019 (COVID-19) pandemic, global governing bodies prioritized transmissibility-based precautions and hospital capacity as the foundation for delay of elective procedures. As elective surgical volumes increased, convalescent COVID-19 patients faced increased postoperative morbidity and mortality and clinicians had limited evidence for stratifying individual risk in this population. Clear evidence now demonstrates that those recovering from COVID-19 have increased postoperative morbidity and mortality. These data-in conjunction with the recent American Society of Anesthesiologists guidelines-offer the evidence necessary to expand the early pandemic guidelines and guide the surgeon's preoperative risk assessment. Here, we argue elective surgeries should still be delayed on a personalized basis to maximize postoperative outcomes. We outline a framework for stratifying the individual COVID-19 patient's fitness for surgery based on the symptoms and severity of acute or convalescent COVID-19 illness, coagulopathy assessment, and acuity of the surgical procedure. Although the most common manifestation of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection is COVID-19 pneumonitis, every system in the body is potentially afflicted by an endotheliitis. This endothelial derangement most often manifests as a hypercoagulable state on admission with associated occult and symptomatic venous and arterial thromboembolisms. The delicate balance between hyper and hypocoagulable states is defined by the local immune-thrombotic crosstalk that results commonly in a hemostatic derangement known as fibrinolytic shutdown. In tandem, the hemostatic derangements that occur during acute COVID-19 infection affect not only the timing of surgical procedures, but also the incidence of postoperative hemostatic complications related to COVID-19-associated coagulopathy (CAC). Traditional methods of thromboprophylaxis and treatment of thromboses after surgery require a tailored approach guided by an understanding of the pathophysiologic underpinnings of the COVID-19 patient. Likewise, a prolonged period of risk for developing hemostatic complications following hospitalization due to COVID-19 has resulted in guidelines from differing societies that recommend varying periods of delay following SARS-CoV-2 infection. In conclusion, we propose the perioperative, personalized assessment of COVID-19 patients' CAC using viscoelastic hemostatic assays and fluorescent microclot analysis.

RESUMO

INTRODUCTION: Hypertrophic cardiomyopathy (HCM) is a genetic disorder that can be complicated by heart failure and sudden cardiac death. Pregnancy causes hemodynamic changes, which may be deleterious in patients with HCM. Existing cohort studies, analyzing maternal and fetal outcomes of pregnant HCM patients, are limited by small sample sizes. We performed a systematic review of maternal and fetal outcomes of pregnancy in patients with HCM. METHODS: We performed a literature search for studies reporting maternal or fetal outcomes in pregnant women with HCM. Primary outcomes included maternal death, stillbirth, and fetal death. Secondary maternal outcomes included both sustained and non-sustained ventricular tachycardia (VT), atrial fibrillation, heart failure (HF), syncope, cesarean delivery, and preeclampsia/eclampsia. The secondary fetal outcome was preterm birth. We used a random-effects model to determine pooled incidences of outcomes. RESULTS: We identified a total of 18 studies with 1624 pregnancies. The incidence of maternal death was 0.2%. The rates of sustained VT, any VT (including non-sustained), AF, HF, and syncope were 1% (0-1%), 6% (4-8%), 4% (2-6%), 5% (3-8%), and 9% (3-14%), respectively. Postpartum hemorrhage, preeclampsia/eclampsia, and cesarean section complicated 2% (1-4%), 4% (2-6%), and 43% (32-54%) of pregnancies, respectively. Neonatal death occurred in 0.2% of pregnancies. Stillbirth complicated 1% (95% CI, 0-3%) of pregnancies, whereas the incidence of preterm birth was 22% (95% CI, 18-25%). CONCLUSIONS: Women with HCM considering pregnancy can be reassured that the risk of maternal, fetal, or neonatal death is low. However, they are at risk of several non-fatal cardiac and pregnancy-related complications.

RESUMO

BACKGROUND: Colistin use is increasing with the rise in MDR Gram-negative infections globally. Effective antibiotic stewardship is essential to preserve this antibiotic of last resort. OBJECTIVES: This study investigated stewardship and safety errors related to colistin use to identify opportunities for improvement. PATIENTS AND METHODS: A prospective descriptive study involving all patients 13 years and older treated with colistin at a tertiary hospital in Cape Town, South Africa, between August 2018 and June 2019. We collected clinical, laboratory and outcome data and assessed provided treatment for stewardship and safety errors. RESULTS: We included 44 patients. Treatment errors were identified for 34 (77%) patients (median = 1), most commonly inadequate monitoring of renal function (N = 16, 32%). We also identified no rational indication for colistin (N = 9, 20%), loading dose error (N = 12, 27%); maintenance dose error (N = 10, 23%); no prior culture (N = 11, 25%); and failure to de-escalate (2 of 9) or adjust dose to changes in renal function (6 of 15). All cause in-hospital mortality was 47%. Amongst survivors, median ICU stay was 6 days and hospital stay more than 30 days. Eight (18%) patients developed renal injury or failure during treatment. Three (7%) patients in this study were found to have colistin-resistant organisms including two prior to colistin exposure. CONCLUSIONS: This study has identified opportunities to enhance colistin stewardship and improve efficacy and safety of prescription. The appearance of colistin-resistant organisms reinforces the urgent need to ensure effective and appropriate use of colistin.

RESUMO

BACKGROUND: Healthcare workers are at increased risk of contracting severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and potentially causing institutional outbreaks. Staff testing is critical in identifying and isolating infected individuals, whilst also reducing unnecessary workforce depletion. Tygerberg Hospital implemented an online pre-registration system to expedite staff and cluster testing. We aimed to identify specific presentations associated with a positive or negative result for SARS-CoV-2. METHODS: A retrospective descriptive study design involving all clients making use of the hospital's pre-registration system during May 2020. RESULTS: Of 799 clients, most were young and females with few comorbidities. Nurses formed the largest staff contingent in the study, followed by administrative staff, doctors and general assistants. Doctors tested earlier compared with other staff (median: 1.5 vs. 4 days). The most frequent presenting symptoms included headache, sore throat, cough and myalgia. Amongst those testing positive (n = 105), fever, altered smell, altered taste sensation, and chills were the most common symptoms. Three or more symptoms were more predictive of a positive test, but 12/145 asymptomatic clients also tested positive. CONCLUSION: Staff coronavirus testing using an online pre-registration form is a viable and acceptable strategy. Whilst some presentations are less likely to be associated with SARS-CoV-2 infection, no symptom can completely exclude it. Staff testing should form part of a bundle of strategies to protect staff, including wearing masks, regular handwashing, buddy screening, physical distancing, availability of personal protective equipment and special dispensation for coronavirus disease 2019 (COVID-19)-related leave.

RESUMO

BACKGROUND: Constipation is an important and highly prevalent predictor of inadequate bowel preparation during colonoscopy. In North America, between 2 and 28% of the general population suffer from constipation. Despite the high prevalence of constipation, to our knowledge, no meta-analysis on the optimal bowel preparation for constipated patients has been performed. We aimed to systematically review the literature to determine the ideal bowel preparation regiment for patients with chronic constipation. METHODS: A comprehensive search of electronic databases (MEDLINE, EMBASE, SCOPUS, and Web of Science) was performed. We included studies that assessed the quality of bowel preparation in constipated patients receiving different agents prior to colonoscopy. The primary outcome was colon cleanliness. Secondary outcomes included tolerability of the bowel preparation and serious adverse events. RESULTS: Preliminary database search yielded 1581 articles after duplicates were removed. After screening of the titles and abstracts using the exclusion criteria, 358 full-text articles were retained. Full-text articles were reviewed and eight studies meeting the inclusion criteria were included for qualitative synthesis. Three randomized controlled trials identified a total of 1636 constipated patients, of whom 225 were eligible for meta-analysis. Of those, 107 (47.6%) received NaP and 118 (52.4%) received PEG. Patients receiving NaP before colonoscopy had a higher chance of a successful bowel preparation than patients receiving PEG (OR 1.87, CI 1.06 to 3.32, P = 0.003). In the studies comparing PEG to NaP, two found that NaP resulted in greater tolerability of the bowel preparation and one study found that PEG resulted in superior tolerability. CONCLUSIONS: In chronically constipated patients undergoing colonoscopy, the use of NaP may result in superior colonic cleanliness when compared to PEG, however, quality of evidence was low. Further high-quality studies are required to delineate the optimal bowel preparation in patients with constipation.

RESUMO

The lockdown and physical distancing strategies imposed to combat COVID-19 have caused seismic shifts at all levels of society. Hospitals have been particularly affected. Healthcare workers (HCW's) wore PPE during all patient interactions and visitors were prohibited. Life for a patient became lonelier and for those with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) measures were even more severe. HCW's must treat patients following a biopsychosocial approach and promote communication between patients and loved ones. We implemented a low cost Video Call Visit system at Tygerberg Hospital, Cape Town. In this article we discuss the elements of a successful implementation and potential pitfalls in the context of a pandemic, notably cross-infection and privacy. Rapid but responsible innovation using 21st century tools was required to address the many challenges of the pandemic, including improving the lived experience for patients and families. These should be intended to last after the pandemic has passed.

RESUMO

BACKGROUND: Ventral hernias are a common finding during bariatric surgery; however, the risks and benefits of repair during surgery remain unclear. Using the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) database, we examined the short-term outcomes of patients undergoing bariatric surgery with concurrent ventral hernia repair (VHR) versus bariatric surgery alone. METHODS: Patients undergoing laparoscopic Roux-en-Y gastric bypass (LRYGB) or laparoscopic sleeve gastrectomy (LSG) were included. A propensity-matched analysis was performed between laparoscopic bariatric surgery with and without concurrent VHR. The primary outcome was the 30-day major complication rate which includes but is not limited to 30-day reoperation, deep surgical site infection, and sepsis. Secondary outcomes included operative time, length of hospital stay, 30-day readmission, and 30-day mortality. RESULTS: A total of 430,225 patients were included, of which 4690 (1.1%) received concomitant VHR. With one-to-one propensity score matching, 4648 pairs were selected. Concurrent VHR was associated with a higher major complication rate (5.8 vs 3.8%, p < 0.001) but no significant difference in mortality (0.3 vs 0.2%, p = 0.531). Both LSG with VHR (3.2 vs 2.4%, p = 0.007) and RYGB with VHR (9.3 vs 5.7%, p < 0.001) were associated with an increase in major complications. CONCLUSIONS: Patients undergoing VHR during bariatric surgery do not experience higher mortality. However, these patients have an elevated risk of major complications with this risk being higher among patients undergoing VHR and LRYGB. Bariatric surgeons should consider these risks when choosing to perform VHR at the time of bariatric surgery.

RESUMO

BACKGROUND: Simethicone is an adjunct frequently used during bowel preparation before colonoscopy and currently there is no consensus on whether it should be recommended in standard bowel preparation. We performed a systematic review and meta-analysis to determine the effect simethicone has on bowel cleanliness, adenoma detection rate (ADR), and tolerability. METHODS: We searched the literature for studies that compared colon cleansing of patients that received standard bowel preparation alone and in combination with simethicone prior to colonoscopy. The primary outcomes were colon cleanliness, ADR, and tolerability. RESULTS: Sixteen randomized controlled trials with 5630 patients were included in meta-analysis. Overall, polyethylene glycol (PEG) with simethicone improves colon cleansing compared with PEG alone (odds ratio [OR] 1.48, CI 1.11 to 1.97, P = 0.008). This improvement was seen for single dosing (OR 1.83, CI 1.20 to 2.79, P = 0.005) but not for split dosing (OR 1.32, CI 0.72 to 2.43, P = 0.38). Overall, simethicone had no effect on ADR (OR 1.22, CI 0.81 to 1.83, P = 0.33), but in patients receiving single dosing, simethicone significantly increased ADR (OR 1.96, CI 1.22 to 3.16, P = 0.005). The rates of nausea (OR 0.96, CI 0.75 to 1.24, P = 0.75), vomiting (OR 1.00, CI 0.69 to 1.44, P = 0.99), and abdominal pain (OR 0.69, CI 0.40 to 1.18, P = 0.17) were not significantly different between PEG and PEG + simethicone cohorts. For abdominal bloating, the PEG cohort had greater odds of experiencing bloating than the PEG + simethicone cohort (OR 2.33, CI 1.70 to 3.20, P < 0.00001). CONCLUSIONS: Simethicone improves colon cleanliness and ADR; however, this improvement is not seen in patients receiving split-dose PEG. Furthermore, simethicone decreases abdominal bloating but has no effect on nausea, vomiting, and abdominal pain. Simethicone may be a useful bowel preparation adjunct in patients unable to receive split-dose PEG.

RESUMO

BACKGROUND: Obesity is associated with disturbances in the gut microbiota which is a risk factor for Clostridium difficile infection (CDI). Bariatric surgery can induce substantive changes to the gut microbiota which may affect the risk of developing CDI. METHODS: The Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program captures variables specific to bariatric surgery from 832 centers. Patients undergoing laparoscopic Roux-en-Y gastric bypass (LRYGB) or laparoscopic sleeve gastrectomy (LSG) in 2016 and 2017 were identified. Primary outcomes included the prevalence and predictors of CDI after bariatric surgery. A multivariable logistic regression model determined preoperative factors predictive of 30-day CDI. RESULTS: A total of 78,222 LRYGB and 222,968 LSG were included. The overall incidence of CDI was low with 0.13% developing CDI. Rates of CDI were two times higher after LRYGB compared to LSG (0.2 vs 0.1%, p < 0.001). Although CDI rates were low, CDI was associated with increased post-operative complications. Multivariable analysis identified chronic kidney disease (OR 2.37, 95%CI 1.09-5.15, p = 0.03) and history of venous thromboembolism (OR 2.06, 95%CI 1.29-3.29, p = 0.002) as being most predictive of developing CDI with more than a twofold increase in risk. Patients undergoing LRYGB had an increased risk of CDI compared to LSG (OR 1.65, 95%CI 1.31-2.09, p < 0.001). White race, female sex, and obstructive sleep apnea also increased risk of CDI. CONCLUSIONS: The incidence of CDI following bariatric surgery is relatively low with LRYGB having a higher risk than LSG.

RESUMO

Reports about The Horn of Africa Famine Crisis in 2011 flooded our news bulletins and newspapers. Yet the nations of the world failed to respond and alleviate the unfolding disaster. In August 2011, the Gift of the Givers Foundation mobilised what was to become the largest humanitarian mission ever conducted by an African organisation. Almost a year later, the effort continues, changing the face of disaster medicine as we know it.
