ABSTRACT

Background: Understanding factors that impact HIV viral load (VL) accuracy in resource-limited settings is key to quality improvement. Objective: We evaluated whether testing delay and specimen storage between 25 °C and 30 °C before testing affected results. Methods: Between November 2019 and June 2023, 249 individuals on antiretroviral therapy, or with newly diagnosed HIV, were recruited from clinics in Cape Town and Gqeberha, South Africa, and three plasma preparation tubes were collected. One tube was tested within 24 h, while the others were stored uncentrifuged at ambient temperatures before testing. Centrifugation and testing of matched samples were performed on Day 4 and Day 7 after collection. Results: Time delay and ambient storage had minimal impact in specimens with a Day 1 VL of > 100 copies/mL. When grouped by Day 1 VL range, 96% - 100% of specimens at Day 4 and 93% - 100% at Day 7 had VLs within 0.5 log copies/mL of the first result. The greatest variability at Days 4 and 7 was observed when the Day 1 VL was < 100 copies/mL. However, there was no trend of increasing difference over time. Of Day 1 specimens with undetectable VL, or VL < 50 copies/mL, 80% had concordant results at Day 4 and 78% at Day 7. Conclusion: These results show that VL is stable in plasma preparation tubes for 7 days when stored at room temperature. There is significant variability in specimens with low VL, but variability is not affected by testing delay. What this study adds: Ideal HIV VL testing conditions are frequently unachievable in resource-limited settings. Data are needed on whether this impacts on the validity of test results. Our results provide reassurance that storage at ambient temperature for up to 7 days before testing does not substantially affect the VL result.

ABSTRACT

Introduction: there has been significant global variation in Coronavirus Disease (COVID-19) mortality at different time points in the pandemic. Contributing factors include population demographics, comorbidities, health system capacity, prior infection with COVID-19, vaccinations, and viral variants. The study aims to describe COVID-19-related mortality of inpatients at Helen Joseph Hospital (HJH), over 12 months, during the first two waves of the COVID-19 pandemic in South Africa. The primary objectives were to describe the socio-demographic details, clinical characteristics, and hospital outcomes during the first and second waves of COVID-19. This included an assessment of the in-hospital case fatality ratio (CFR) of patients admitted with COVID-19. The secondary objectives were to compare the socio-demographic details, clinical characteristics, and outcomes between the two waves, and to determine risk factors associated with COVID-19-related mortality. Methods: this is a retrospective cohort study of all inpatient laboratory-confirmed COVID-19 cases at HJH from 1st May 2020 to 31st April 2021. Data were collected by the National Institute for Communicable Diseases (NICD). Bivariate analysis was performed to describe and compare the socio-demographic characteristics, clinical characteristics, and hospital admission outcomes between the two waves. Multivariate logistic regression was used to determine risk factors for COVID-19-related mortality. Results: overall, 1359 patients were admitted, 595 in wave one, and 764 in wave two. Patients were predominantly male (52.4%), of Black African race (75.1%) with a mean age of 54.6 (standard deviation 15.4) years. The median length of stay was 8 days (interquartile range 5-14 days). In total, 73.2% (995) of patients required oxygen, 5.2% (71) of patients received mechanical ventilation, and 7.1% (96) were admitted to the high care and Intensive Care Unit (ICU). The most common comorbid illnesses were hypertension (36.7%, n=499), diabetes mellitus (26.6%, n=362), Human Immunodeficiency Virus (HIV) (10.8%, n=147), and obesity (11.0%, n=149). The in-hospital CFR during the first wave was 30.4% (181/595) and 25.5% (195/764) (p<0.001) in the second wave, and overall, in-hospital CFR was 27.7% (376/1359). The adjusted odds of death were 79% higher among patients admitted during wave one compared to wave two (aOR=1.79; 95% CI: 1.35-2.38). A one-year increase in age increased the odds of death by 4% (aOR=1.04; 95% CI: 1.03-1.05). The need for oxygen (aOR=2.17, 95%CI: 1.56-3.01) and ventilation (aOR=7.23, 95% CI: 4.02-13.01) were significant risk factors for mortality. Conclusion: prior to the availability of vaccines, COVID-19-related mortality was high and risk factors for mortality were consistent with national and international findings. This study reflects the impact of the pandemic on the South African public sector with limited resources and minimal ICU capacity.

ABSTRACT

The consequences of falsely reactive HIV test results can be significant, for patients and healthcare providers. This case describes a diagnostic investigation of a patient with pronounced discordant HIV serological results, to determine HIV status. The fourth generation serological screening assay (Roche COBAS Elecsys HIV combiPT) had high positive results but confirmatory testing was negative (Abbott HIV Ag/Ab Combo). Five separate samples over 13 days were tested using multiple fourth generation HIV immunoassays and molecular tests for HIV-1 and HIV-2. Potential causes of falsely reactive serological results were investigated. Samples were sent to the manufacturer for analysis. The screening assay was positive on all samples with a very high signal to cut-off ratio (S/CO) of greater than 400. However, multiple serological and molecular assays did not detect HIV-1 or HIV-2 specific antibodies, antigen or nucleic acid. A recombinant immunochromatographic assay had faint reactivity to gp41 peptide and the manufacturer investigation reported cross-reactivity to one of the screening assay's synthetic peptides. Possible causes of the false positive result include cross reactivity to other antigens, including prior schistosomiasis infection, or the patient's previously excised ameloblastoma (a rare germ cell tumor of the jaw). This is a rare case of false high positive results on fourth-generation HIV serology testing due to high level non-specific reactivity to an isolated synthetic peptide component of the assay. It highlights the need for confirmatory testing even in settings with HIV high prevalence and awareness that false-positive serological results may have a high S/CO.

ABSTRACT

BACKGROUND: Paediatric patients (PPs) often feel that they are not involved in care and treatment decisions. Although training clinicians may help, there is a lack of evaluated training programmes specifically for work with PPs. The aim of this article is to evaluate 'Me first', a training programme aimed at improving clinicians' attitudes and communication skills when working with PPs. METHODS: A total of 69 clinicians attended 'Me first' training and completed questionnaires across three time points: (1) prior to attending the training; (2) at the end of the training; and (3) 4-6 weeks later. This included 14 medical staff, 29 nursing staff and 26 allied health staff. Attitude was measured using the Leeds Attitudes to Concordance II (LATCon II) scale, and communication skills were measured using the Effective Listening and Interactive Communication Scale (ELICS). RESULTS: Overall, clinicians reported that their attitude and communication skills improved after attending 'Me first'. This was maintained 4-6 weeks later. Subgroup analysis showed that allied health staff did not maintain the improved attitude at the follow-up conducted 4-6 weeks later. Subgroup analysis showed that allied health staff did not maintain the improved attitude at the follow-up conducted 4-6 weeks later CONCLUSIONS: Findings suggest that 'Me first' may be helpful in improving clinician attitudes and communication skills with PPs. Further research should examine whether PPs report higher levels of communication and decision making with clinicians who have attended training.

ABSTRACT

This article explores communication and decision-making with children and young people in healthcare. Children and young people report that healthcare professionals are good at explaining and helping them to understand what will happen to them, but that they do not feel involved in decision-making about their care or treatment. To improve communication with children and young people, they need to be involved in decision-making about their care and treatment. In partnership with children, young people and healthcare professionals Common Room Consulting, Great Ormond Street Hospital for Children NHS Foundation Trust and Health Education England have co-produced a communication model, Me first, to support decision-making with children and young people in healthcare. This article introduces the Me first model and explores how it can be applied in clinical practice.

ABSTRACT

The purpose of the current study was to describe male breast cancer in Johannesburg, South Africa, and assess whether male breast cancer patients' perception of their own masculinity was affected by having a cancer commonly seen in women. A retrospective file review was carried out at two hospitals, one private and one government, of male breast cancer patients from 2007 to 2012 followed by a telephone survey of patients identified during review. Of approximately 3,000 breast cancer patients seen in the 5 years reviewed, 23 cases of male breast cancer were identified. Most were diagnosed with invasive ductal carcinoma ( n = 19, 83%). Stage at presentation was from stages 0 to 3 (Stage 0 [ n = 2, 9%], Stage 1 [ n = 3, 13%], Stage 2 [ n = 12, 52%], Stage 3 [ n = 6, 26%]) and no patients were metastatic at presentation. The telephonic survey was completed by 18 patients (78%). Nearly all ( n = 17/18) shared their diagnosis with family and close friends. Two thirds of patients delayed presentation and government hospital patients were more likely to present later than private sector hospital patients. Although most male breast cancer patients sampled did not perceive the breast cancer diagnosis as affecting their masculinity, Black men and those treated in government hospitals were less likely to be aware of male breast cancer, and were more likely to have their perception of their own masculinity affected.

ABSTRACT

CONTEXT: A lower free T(4) (fT4), within the euthyroid range, has been shown in adults to associate with an adverse metabolic phenotype. Thyroid physiology changes significantly during gestation and affects maternal and fetal well-being. OBJECTIVE: The aim of the study was to test the hypothesis that a lower serum fT4 in healthy euthyroid pregnant women is related to a less favorable metabolic phenotype and to fetal or placental weight. DESIGN, SETTING, PATIENTS, AND OUTCOME MEASURES: We examined associations of thyroid function tests (TSH and fT4) and the free T(3) (fT3)-to-fT4 ratio (as a proxy of deiodinase activity) with a metabolic profile [preload and postload glucose, glycosylated hemoglobin (HbA1c), high molecular-weight (HMW)-adiponectin, homeostasis model of assessment for insulin resistance (HOMA-IR), and serum lipids] in 321 healthy pregnant women. All women were euthyroid and had negative anti-thyroid peroxidase antibodies. None received thyroid hormone replacement. Blood tests were performed in women between 24 and 28 wk gestation. Placentas and newborns were weighed at birth. RESULTS: Circulating TSH did not relate to metabolic parameters, but decreasing fT4 and increasing fT3-to-fT4 ratio associated with a less favorable metabolic phenotype, as judged by higher postload glucose, HbA1c, fasting insulin, HOMA-IR, and triglycerides, and by a lower HMW-adiponectinemia (all P ≤ 0.005). In multiple regression analyses, fT4 was independently associated with HbA1c (ß = -0.135; P = 0.038), HMW-adiponectin (ß = 0.218; P < 0.001), and placental weight (ß = -0.185; P < 0.005), whereas the fT3-to-fT4 ratio was independently associated with maternal body mass index (ß = 0.265; P < 0.001), HMW-adiponectinemia (ß = -0.237; P < 0.002), HOMA-IR (ß = 0.194; P = 0.014), and placental weight (ß = 0.174; P = 0.020). CONCLUSION: In pregnant women without a history of thyroid dysfunction, lower concentrations of fT4 and a higher conversion of fT4 to fT3, as inferred by changes in the fT3-to-fT4 ratio, were found to be associated with a less favorable metabolic phenotype and with more placental growth.

ABSTRACT

This paper considers evidence of the effectiveness of a non-governmental organization (NGO) primary health care programme in rural Bangladesh. It is based on data from the programme's management information system reported by 27 partner NGOs from 1996-2002. The data indicate relatively high coverage has been achieved for reproductive and child health services, as well as lower infant and child mortality. On the basis of a crude indicator of socio-economic status, the programme is poverty-focused. There is good service coverage among the poorest one-third and others, and the infant and child mortality differential has been eliminated over recent years. A rapid decline in infant mortality among the poorest from 1999-2002 reflects a reduction in neonatal mortality of about 50%. Allowing for some under-reporting and possible misclassification of deaths to the stillbirths category, neonatal mortality is relatively low in the NGO areas. The lower child and maternal mortality for the NGO areas combined, compared with estimates for Bangladesh in recent years, may at least in part be due to high coverage of reproductive and child health services. Other development programmes implemented by many of the NGOs could also have contributed. Despite the limited resources available, and the lower infant and child mortality already achieved, there appears to be scope for further prevention of deaths, particularly those due to birth asphyxia, acute respiratory infection, diarrhoeal disease and accidents. Maternal mortality in the NGO areas was lower in 2000-02 than the most recent estimate for Bangladesh. Further reduction is likely to depend on improved access to qualified community midwives and essential obstetric care at government referral facilities.
