RESUMO

Coronavirus disease-2019 (COVID-19) is the leading cause of death worldwide from a single infectious agent. Whether or not HIV infection affects clinical outcomes in patients with COVID-19 remains inconclusive. This study aimed to compare the clinical outcomes of people living with HIV (PLWH) and non-HIV-infected patients hospitalized during the second wave of the COVID-19 pandemic in Uganda. We retrospectively retrieved data on patients with COVID-19 who were admitted to the Mulago National Referral Hospital in Uganda between April 2021 and mid-July 2021. We performed propensity-score-matching of 1:5 to compare outcomes in COVID-19 patients living with and those without HIV coinfection (controls). We included 31 PLWH and 155 non-HIV controls. The baseline characteristics were similar across groups (all p values > 0.05). PLWH had close to threefold higher odds of having ICU consultation compared to controls (odds ratio [OR]: 2.9, 95% CI: 1.2-6.9, p = 0.015). There was a trend toward having a severe or critical COVID-19 illness among PLWHIH compared to controls (OR: 1.9, 95% CI: 0.8-4.7, p = 0.164). Length of hospitalization was not significantly different between PLWH and non-HIV controls (6 days vs. 7 days, p = 0.184). Seven-day survival was 63% (95% CI: 42%-78%) among PLWH and 72% (95% CI: 61%-82%) among controls while 14-day survival was 50% (95% CI: 28%-69%) among PLWH and 65% (95% CI: 55%-73%) among controls (p = 0.280). There was another trend toward having 1.7-fold higher odds of mortality among PLWH compared to controls (OR: 1.7, 95% CI: 0.8-3.8, p = 0.181). Our data suggest that PLWH may be at an increased risk of severe or critical COVID-19 illness requiring ICU consultation. Further studies with larger sample sizes are recommended.

RESUMO

BACKGROUND: Nigeria hosts much of Africa's morbidity and mortality from emergency medical conditions. We surveyed providers at seven Nigerian Accident & Emergency (A&E) units about (i) their unit's ability to manage six major types of emergency medical condition (sentinel conditions) and (ii) barriers to performing key functions (signal functions) to manage sentinel conditions. Here, we present our analysis of provider-reported barriers to signal function performance. METHODS: 503 Health Providers at 7 A&E units, across 7 states, were surveyed using a modified African Federation of Emergency Medicine (AFEM) Emergency Care Assessment Tool (ECAT). Providers indicating suboptimal performance ascribed this performance to any of eight multiple-choice barriers [infrastructural issues, absent and broken equipment, inadequate training, inadequate personnel, requirement of out-of-pocket payment, non-indication of that signal function for the sentinel condition, and hospital-specific policies barring signal function performance] or an open-ended "other" response. The average number of endorsements for each barrier was obtained for each sentinel condition. Differences in barrier endorsement were compared across site, barrier type and sentinel condition using a three-way ANOVA test. Open-ended responses were evaluated using inductive thematic analysis. Sentinel conditions were Shock, Respiratory Failure, Altered Mental Status, Pain, Trauma, and Maternal & Child Health. Study sites were the University of Calabar Teaching Hospital, the Lagos University Teaching Hospital, the Federal Medical Center, Katsina, the National Hospital Abuja, the Federal Teaching Hospital Gombe, the University of Ilorin Teaching Hospital (Kwara), and the Federal Medical Center Owerri (Imo). FINDINGS: Barrier distribution varied widely by study site. Just three study sites shared any one barrier to signal function performance as their most common. The two barriers most commonly endorsed were (i) non-indication of, and (ii) insufficient infrastructure to perform signal functions. A three-way ANOVA test found significant differences in barrier endorsement by barrier type, study site and sentinel condition (p<0.05). Thematic analysis of open-ended responses highlighted (i) considerations disfavoring signal function performance and (ii) lack of experience with signal functions as barriers to signal function performance. Interrater reliability, calculated using Fleiss' Kappa, was found to be 0.5 across 11 initial codes and 0.51 for our two final themes. INTERPRETATION: Provider perspective varied with regards to barriers to care. Despite these differences, the trends seen for infrastructure reflect the importance of sustained investment in Nigerian health infrastructure. The high level of endorsement seen for the non-indication barrier may signal need for better ECAT adaptation for local practice & education, and for improved Nigerian emergency medical education and training. A low endorsement was seen for patient-facing costs, despite the high burden of Nigerian private expenditure on healthcare, indicating limited representation of patient-facing barriers. Analysis of open-ended responses was limited by the brevity and ambiguity of these responses on the ECAT. Further investigation is needed towards better representation of patient-facing barriers and qualitative approaches to evaluating Nigerian emergency care provision.

RESUMO

INTRODUCTION: Almajirai are male children in Northern Nigeria and Southern Niger who study Islam in the almajiranci system. Almajiranci has been associated with non-participation in formal education, abuse, poverty, and underdevelopment. However, the peer-reviewed literature around health among almajirai remains limited. We conduct a scoping review around almajiri health to synthesize evidence for health problems, draw links between findings, identify research gaps, indicate areas for intervention, and assess participatory approaches in this literature. METHODS: We searched the academic literature for articles concerning almajiri heath using a framework integrating the biopsychosocial and socio-ecological models of health. We included articles in English and French published between 2000 and 2022. For each study we collected information regarding authorship, study year and location(s), study design and aims, sample characteristics, findings, and almajiri participation in research design, execution, interpretation and dissemination. RESULTS: Of 1,944 studies, 17 were found relevant for data extraction. These included 14 cross-sectional studies, 2 descriptive articles, and one case-control study. All were conducted in Nigeria, though one included Nigerien almajirai. No study engaged almajirai in participatory roles. Domains evaluated included infectious disease (10 studies), oral health (2 studies), workplace injury, nutrition, health status, health determinants, and mental health (1 study each). Almajirai included ranged from 3 to 28 years old. Included studies found high rates of malaria, intestinal parasitosis, urinary tract infection, N. meningitidis, and occupational injury among almajirai. Studies comparing almajirai to controls found significantly higher rates of cholera, urinary schistosomiasis, and psychiatric disorders, lower levels of rabies awareness and poorer oral hygiene among almajirai (p<0.05). One study, concerning nutrition, described an intervention to improve almajiri health, though did not provide health outcomes for that intervention. CONCLUSION: We find that the literature around almajiri health has concerned a broad range of domains, though the number of studies within each domain remains limited. We further note limitations in the geographic scope of this literature, interventions to improve almajiri health, and the consideration of demographic features, like age, that may influence almajiri health. We stress the need for further study in these areas, and for participatory approaches, which may be more likely to effectively improve almajiri health.

RESUMO

BACKGROUND: We evaluated clinical outcomes of patients hospitalized with coronavirus disease 2019 (COVID-19) in the second wave of the pandemic in a national COVID-19 treatment unit (CTU) in Uganda. METHODS: We conducted a retrospective cohort study of COVID-19 patients hospitalized at the Mulago National Referral Hospital CTU between May 1 and July 11, 2021. We performed Kaplan-Meier analysis to evaluate all-cause in-hospital mortality. RESULTS: Of the 477 participants, 247 (52%) were female, 15 (3%) had received at least 1 dose of the COVID-19 vaccine, and 223 (46%) had at least 1 comorbidity. The median age was 52 (interquartile range, 41-65) years. More than 80% of the patients presented with severe (19%, n=91) or critical (66%, n=315) COVID-19 illness. Overall, 174 (37%) patients died. Predictors of all-cause in-hospital mortality were as follows; age ≥50 years (adjusted odds ratio [aOR], 1.9; 95% confidence interval [CI], 1.2-3.2; P=.011), oxygen saturation at admission of ≥92% (aOR, 0.97; 95% CI, 0.91-0.95; P<.001), and admission pulse rate of ≥100 beats per minute (aOR, 1.01; 95% CI, 1.00-1.02; P=.042). The risk of death was 1.4-fold higher in female participants compared with their male counterparts (hazards ratio, 1.4; 95% CI, 1.0-2.0; P=.025). CONCLUSIONS: In this cohort, where the majority of the patients presented with severe or critical illness, more than one third of the patients hospitalized with COVID-19 at a national CTU died of the illness.

RESUMO

BACKGROUND: Anastomotic complications are among the most devastating consequences of gastrointestinal surgery. Despite its high morbidity, the factors responsible for anastomotic regeneration following surgical construction remain poorly understood. The aim of this review is to provide an overview of the typical and atypical factors that have been implicated in anastomotic healing. METHODS: A review and analysis of select literature on anastomotic healing was performed. RESULTS: The healing of an anastomotic wound mirrors the phases of cutaneous wound healing- inflammation, proliferation, and remodeling. The evidence supporting much of the traditional dogma for optimal anastomotic healing (ischemia, tension, nutrition) is sparse. More recent research has implicated atypical factors that influence anastomotic healing, including the microbiome, the mesentery, and geometry. As technology evolves, endoscopic approaches may improve anastomotic healing and in some cases may eliminate the anastomosis altogether. DISCUSSION: Much remains unknown regarding the mechanisms of anastomotic healing, and research should focus on elucidating the dynamics of healing at a molecular level. Doing so may help facilitate the transition from traditional surgical dogma to evidence-based medicine in the operating room.

RESUMO

OBJECTIVE: Residents often make career decisions regarding future practice without adequate knowledge to the realities of professional life. Currently there is a paucity of data regarding economic differences between practice models. This study seeks to illuminate the financial differences of surgical subspecialties between academic and private practice. DESIGN: Data were collected from the Association of American Medical College (AAMC) and the Medical Group Management Association's (MGMA) 2015 reports of average annual salaries. Salaries were analyzed for general surgery and 7 subspecialties. Fixed time of practice was set at 30 years. Assumptions included 5 years as assistant professor, 10 years as associate professor, and 15 years as full professor. Formula used: (average yearly salary) × [years of practice (30 yrs - fellowship/research yrs)] + ($50,000 × yrs of fellowship/research) = total adjusted lifetime revenue. RESULTS: As a full professor, academic surgeons in all subspecialties make significantly less than their private practice counterparts. The largest discrepancy is in vascular and cardiothoracic surgery, with full professors earning 16% and 14% less than private practitioners. Plastic surgery and general surgery are the only 2 disciplines that have similar lifetime revenues to private practitioners, earning 2% and 6% less than their counterparts' lifetime revenue. CONCLUSIONS: Academic surgeons in all surgical subspecialties examined earn less lifetime revenue compared to those in private practice. This difference in earnings decreases but remains substantial as an academic surgeon advances. With limited exposure to the diversity of professional arenas, residents must be aware of this discrepancy.

RESUMO

BACKGROUND: The success of an academic surgeon's career is often viewed as directly related to academic appointment; therefore, the sequence of promotion is a demanding, rigorous process. This paper seeks to define the financial implication of academic advancement across different surgical subspecialties. STUDY DESIGN: Data was collected from the Association of American Medical College's 2015 report of average annual salaries. Assumptions included 30 years of practice, 5 years as assistant professor, and 10 years as associate professor before advancement. The base formula used was: (average annual salary) × (years of practice [30 years - fellowship/research years]) + ($50,000 × years of fellowship/research) = total adjusted lifetime salary income. RESULTS: There was a significant increase in lifetime salary income with advancement from assistant to associate professor in all subspecialties when compared to an increase from associate to full professor. The greatest increase in income from assistant to associate professor was seen in transplant and cardiothoracic surgery (35% and 27%, respectively). Trauma surgery and surgical oncology had the smallest increases of 8% and 9%, respectively. With advancement to full professor, the increase in lifetime salary income was significantly less across all subspecialties, ranging from 1% in plastic surgery to 8% in pediatric surgery. CONCLUSION: When analyzing the economics of career advancement in academic surgery, there is a substantial financial benefit in lifetime income to becoming an associate professor in all fields; whereas, advancement to full professor is associated with a drastically reduced economic benefit.

RESUMO

OBJECTIVE: It is believed that spending additional years gaining expertise in surgical subspecialization leads to higher lifetime revenue. Literature shows that more surgeons are pursuing fellowship training and dedicated research years; however, there are no data looking at the aggregate economic impact when training time is accounted for. It is hypothesized that there will be a discrepancy in lifetime income when delay to practice is considered. DESIGN: Data were collected from the Medical Group Management Association's 2015 report of average annual salaries. Fixed time of practice was set at 30 years, and total adjusted revenue was calculated based on variable years spent in research and fellowship. All total revenue outcomes were compared to general surgery and calculated in US dollars. PARTICIPANTS: The financial data on general surgeons and 9 surgical specialties (vascular, pediatric, plastic, breast, surgical oncology, cardiothoracic, thoracic primary, transplant, and trauma) were examined. RESULTS: With fellowship and no research, breast and surgical oncology made significantly less than general surgery (-$1,561,441, -$1,704,958), with a difference in opportunity cost equivalent to approximately 4 years of work. Pediatric and cardiothoracic surgeons made significantly more than general surgeons, with an increase of opportunity cost equivalent to $5,301,985 and $3,718,632, respectively. With 1 research year, trauma surgeons ended up netting less than a general surgeon by $325,665. With 2 research years, plastic and transplant surgeons had total lifetime revenues approximately equivalent to that of a general surgeon. CONCLUSIONS: Significant disparities exist in lifetime total revenue between surgical subspecialties and in comparison, to general surgery. Although most specialists do gross more than general surgeons, breast and surgical oncologists end up netting significantly less over their lifetime as well as trauma surgeons if they do 1 year of research. Thus, the economic advantage of completing additional training is dependent on surgical field and duration of research.

RESUMO

Unlike breast cancer that is positive for estrogen receptor-α (ERα), there are no targeted therapies for triple-negative breast cancer (TNBC). ERα is silenced in TNBC through epigenetic changes including DNA methylation and histone acetylation. Restoring ERα expression in TNBC may sensitize patients to endocrine therapy. Expression of c-Src and ERα are inversely correlated in breast cancer suggesting that c-Src inhibition may lead to reexpression of ERα in TNBC. KX-01 is a peptide substrate-targeted Src/pretubulin inhibitor in clinical trials for solid tumors. KX-01 (1 mg/kg body weight-twice daily) inhibited growth of tamoxifen-resistant MDA-MB-231 and MDA-MB-157 TNBC xenografts in nude mice that was correlated with Src kinase inhibition. KX-01 also increased ERα mRNA and protein, as well as increased the ERα targets progesterone receptor (PR), pS2 (TFF1), cyclin D1 (CCND1), and c-myc (MYC) in MDA-MB-231 and MDA-MB-468, but not MDA-MB-157 xenografts. MDA-MB-231 and MDA-MB-468 tumors exhibited reduction in mesenchymal markers (vimentin, ß-catenin) and increase in epithelial marker (E-cadherin) suggesting mesenchymal-to-epithelial transition (MET). KX-01 sensitized MDA-MB-231 and MDA-MB-468 tumors to tamoxifen growth inhibition and tamoxifen repression of the ERα targets pS2, cyclin D1, and c-myc. Chromatin immunoprecipitation (ChIP) of the ERα promoter in KX-01-treated tumors demonstrated enrichment of active transcription marks (acetyl-H3, acetyl-H3Lys9), dissociation of HDAC1, and recruitment of RNA polymerase II. Methylation-specific PCR and bisulfite sequencing demonstrated no alteration in ERα promoter methylation by KX-01. These data demonstrate that in addition to Src kinase inhibition, peptidomimetic KX-01 restores ERα expression in TNBC through changes in histone acetylation that sensitize tumors to tamoxifen.Implications: Src kinase/pretubulin inhibitor KX-01 restores functional ERα expression in ERα- breast tumors, a novel treatment strategy to treat triple-negative breast cancer.

RESUMO

Abdominal compartment syndrome (ACS) is a known complication of laparotomy; however, the literature is lacking in regards to treatment of this entity in pregnant patients. We present a case of acute perforated appendicitis in a second trimester primagravida, complicated by gangrenous necrosis of the contiguous bowel with subsequent development of ACS and intra-abdominal sepsis. This was treated with a novel approach, using non-commercial negative pressure wound therapy and open abdomen technique. Gestational integrity was preserved and the patient went on to experience a normal spontaneous vaginal delivery. At 5 years post-delivery the patient has had no surgical complications and her baby has met all developmental milestones.
