Indications and outcomes of emergency obstetric hysterectomy; a 5-year review at the Bafoussam Regional Hospital, Cameroon

Background Emergency Obstetric Hysterectomy (EOH) is removal of the uterus due to life threatening conditions within the puerperium. This life saving intervention is associated with life threatening complications. In our setting, little is known on EOH. Objectives To determine the prevalence, indications and outcomes of emergency obstetric hysterectomy while comparing both postpartum hysterectomy and caesarean hysterectomy. Methods A 5-year hospital-based retrospective cohort study involving medical records of patients who underwent emergency obstetric hysterectomies between 1st January 2015 and 31st December 2019, was carried out at the Bafoussam Regional Hospital (BRH) from 1st February 2020 to 30th April 2020. Cases were classified as caesarean hysterectomy (CH) or postpartum hysterectomy (PH). Epidemiological data, indications, and complications of EOH were collected and analyzed in EPI-INFO 7.2.2.1. The chi-squared test was used to compare the two groups, and bivariate analysis was used to identify indicators of adverse outcomes of EOH. Statistical significance was set at p < 0.05. Results There were 30 cases of emergency obstetric hysterectomy (24 caesarean hysterectomies and 6 postpartum hysterectomies), giving a prevalence rate of 3.75 per 1000 deliveries. The most common indication for CH, was intractable postpartum haemorrhage and uterine rupture (33.33% each), while abnormal placentation (50%) was commonly indicated for PH. Anaemia (both groups) (p = 0.013) and sepsis (PH group only, 33.33%) (p = 0.03) were the most statistically significant complications of EOH respectively. Absence of blood transfusion prior to surgery (p = 0.013) and prolonged surgery lasting 2 or more hours (p = 0.04), were significantly associated with a negative clinical outcome. Conclusion The prevalence of EOH is high. There were no differences in the sociodemographic profile, risk factors and indications of both groups. PH group was more likely to develop sepsis as complication. Lack of blood transfusion prior to surgery and prolonged surgeries were significantly associated to complication. Meticulous care and timely recognition of negative prognostic factors of delivery as well as those of EOH will help improve maternal outcomes of pregnancy.

Analysis of classical neutrophils and polymorphonuclear myeloid-derived suppressor cells in cancer patients and tumor-bearing mice

In this study, using single-cell RNA-seq, cell mass spectrometry, flow cytometry, and functional analysis, we characterized the heterogeneity of polymorphonuclear neutrophils (PMNs) in cancer. We describe three populations of PMNs in tumor-bearing mice: classical PMNs, polymorphonuclear myeloid-derived suppressor cells (PMN-MDSCs), and activated PMN-MDSCs with potent immune suppressive activity. In spleens of mice, PMN-MDSCs gradually replaced PMNs during tumor progression. Activated PMN-MDSCs were found only in tumors, where they were present at the very early stages of the disease. These populations of PMNs in mice could be separated based on the expression of CD14. In peripheral blood of cancer patients, we identified two distinct populations of PMNs with characteristics of classical PMNs and PMN-MDSCs. The gene signature of tumor PMN-MDSCs was similar to that in mouse activated PMN-MDSCs and was closely associated with negative clinical outcome in cancer patients. Thus, we provide evidence that PMN-MDSCs are a distinct population of PMNs with unique features and potential for selective targeting opportunities.

Presentation and outcome of COVID-19 in HIV patients with high viral loads and opportunistic infections: a case series

Coronavirus disease 2019 (COVID-19) is especially severe in patients with underlying chronic conditions, with increased risk of mortality. There is concern that people living with HIV (PLWH), especially those with severe immunosuppression, and COVID-19 may have severe disease and a negative clinical outcome. Most studies on COVID-19 in PLWH are from Asia, Europe and America where population dynamics, antiretroviral treatment coverage and coexisting opportunistic infections may differ from that in sub-Saharan Africa. We report on the clinical profile and outcome of three cases of PLWH co-infected with SARS-CoV-2. They all presented with fever, cough and breathlessness and also had advanced HIV infection as evidenced by opportunistic infections, high HIV viral loads and low CD4 counts. The patients responded favourably to the standard of care and were discharged home. Our findings suggest that PLWH with advanced immunosuppression may not necessarily have an unfavourable disease course and outcome. However, case-controlled studies with a larger population size are needed to better understand the impact of COVID-19 in this patient population.

More than ‘canaries in the gender coal mine’: A transfeminist approach to research on detransition

Detransition is tied to three related but distinct concepts – the act of detransitioning, the ‘detransitioner’ identity, and the negative transition experience – which I refer to collectively using the umbrella term ‘detrans’. Detrans research is inevitably political and value-laden, but different methodologies and research questions lend themselves to divergent goals. Drawing on work in the feminist philosophy of science and transfeminist scholarship, I draw a conceptual distinction between research aligned with the goals of ‘preventing detrans’ vs. ‘supporting detrans’. Existing research has constructed detransition as a negative clinical outcome to be prevented because it has been focused on the causes of detrans and the detrans rate. Research associated with the goal of supporting detrans is defined by its focus on the experience and process of detrans itself. Research on preventing detrans constructs detrans as a divisive issue of zero-sum clinical risk, and it is not oriented toward helping people who detransition or who have a negative transition experience. Research on supporting detrans, in contrast, constructs detrans as an issue of inclusion and can be used to improve the medical and mental health care that detrans people receive. I argue that there is an urgent need for qualitative sociological research involving detrans people. I conclude with some broad guidelines for researchers studying detrans.

Alterations of plasma glutamine and surgical stress in gastric cancer surgery

Background: The plasma glutamine levels are known to decrease after major surgery, which is related to a negative clinical outcome. However, the influence of surgical stress on the decrease in the plasma glutamine concentration is unclear. The aim of this study was to evaluate the change in glutamine in relation to the types of gastrectomy and approaches as well as the amount of surgical stress evaluated by serum interleukin-6(IL-6) as an objective indicator. Methods: This was a prospective observational study. The eligibility criteria were (1) gastric adenocarcinoma of the stomach confirmed by pathology and (2) patients scheduled to receive gastrectomy with lymphadenectomy for gastric cancer. Blood samples were taken at 7 AM on the day of surgery and at 12 h after surgery to measure the plasma glutamine and interleukin-6 (IL-6) levels. Results: Between May 2011 and December 2011, 81 consecutive patients were enrolled in this study. The plasma glutamine level was significantly decreased in all patients, regardless of distal or total gastrectomy and laparoscopic or open surgery. No significant differences were observed in the IL-6 level between total and distal gastrectomy patients or between patients treated via a laparoscopic or open approach. Decreases in the plasma glutamine level were positively correlated with the logarithmically transformed-plasma IL-6 (logIL6) (r =0.471, p<0.001) overall. Conclusions: Decreases in the glutamine concentration depended on the amount of surgical stress. When conducting a clinical trial to evaluate glutamine administration, personalized adjustment may be key to avoiding glutamine depletion in response to surgical stress.

Clindamycin-Induced Rhabdomyolysis in the Setting of Mitochondrial Myopathy

We present a patient with mitochondrial myopathy who developed rhabdomyolysis following treatment with clindamycin. While clindamycin is not yet linked to drug-induced rhabdomyolysis in the literature, other drugs with mechanisms of action similar to clindamycin have been shown to damage human host mitochondria. Given this, we contend that clindamycin may also be capable of causing mitochondrial injury, and that while in otherwise healthy patients it may not produce any negative clinical outcome, it can precipitate rhabdomyolysis in certain patients whose mitochondria are already vulnerable.
