Abstract
OBJECTIVES Despite declining TB notifications in Southern Africa, TB-related deaths remain high. We describe patient- and population-level trends in TB-related deaths in Eswatini over a period of 11 years. METHODS Patient-level (retrospective cohort, from 2009 to 2019) and population-level (ecological analysis, 2009-2017) predictors and rates of TB-related deaths were analysed in HIV-negative and HIV-coinfected first-line TB treatment cases and the population of the Shiselweni region. Patient-level TB treatment data, and population and HIV prevalence estimates were combined to obtain stratified annual mortality rates. Multivariable Poisson regressions models were fitted to identify patient-level and population-level predictors of deaths. RESULTS Of 11,883 TB treatment cases, 1302 (11.0%) patients died during treatment: 210/2798 (7.5%) HIV-negative patients, 984/8443 (11.7%) people living with HIV (PLHIV), and 108/642 (16.8%) patients with unknown HIV-status. The treatment case fatality ratio remained above 10% in most years. At patient-level, fatality risk was higher in PLHIV (aRR 1.74, 1.51-2.02), and for older age and extra-pulmonary TB irrespective of HIV-status. For PLHIV, fatality risk was higher for TB retreatment cases (aRR 1.38, 1.18-1.61) and patients without antiretroviral therapy (aRR 1.70, 1.47-1.97). It decreases with increasing higher CD4 strata and the programmatic availability of TB-LAM testing (aRR 0.65, 0.35-0.90). At population-level, mortality rates decreased 6.4-fold (-147/100,000 population) between 2009 (174/100,000) and 2017 (27/100,000), coinciding with a decline in TB treatment cases (2785 in 2009 to 497 in 2017). Although the absolute decline in mortality rates was most pronounced in PLHIV (-826/100,000 vs. HIV-negative: -23/100,000), the relative population-level mortality risk remained higher in PLHIV (aRR 4.68, 3.25-6.72) compared to the HIV-negative population. CONCLUSIONS TB-related mortality rapidly decreased at population-level and most pronounced in PLHIV. However, case fatality among TB treatment cases remained high. Further strategies to reduce active TB disease and introduce improved TB therapies are warranted.

Abstract
Introduction COVID-19 has had a devastating effect on care homes, increasing both morbidity and mortality of residents and staff. Between 2 March and 12 June 2020, COVID-19 was the main cause of death in male care home residents (33.5%) and second for female (26.6%).1 By 1 May 2020, the death rate from all causes in care homes exceeded that in hospital (6,409 versus 6,397).2 Thus, care homes had to rapidly adapt to facilitate safe care of patients and staff. Method An expert outreach team visited a number of care homes in Surrey and Sussex to explore COVID-19 issues in care homes. Key themes were identified that informed topics for the Virtual Care Home Forum, where a series of virtual teaching, training and peer support sessions were hosted either live or on-demand, accessible for all care home staff. Results 12 sessions were held with an average attendance of 25 people, predominantly care home managers and community healthcare professionals. Real time qualitative feedback was collected and an electronic survey was completed at the end of the series which showed 100% felt the sessions had improved their understanding of the topic, 100% felt the knowledge and skills obtained from the sessions would be useful in their job, 87.5% agreed the sessions would impact or change their practise and 100% felt more supported during the pandemic. Conclusion It has been an unprecedented year for the NHS, and the care home sector has suffered significantly. In order to provide the best level of care for patients and support for our community colleagues, we must work collaboratively, including provision of education and training. To ensure equal access for all, maintaining user-safety and compliance with government legislation, virtual webinars proved to be an excellent modality. We plan to continue providing training, teaching and support through this means in the future.

Abstract
Setting There is little information about the diagnosis and treatment of hepatitis B virus (HBV) infection in people living with HIV (PLHIV) in Zimbabwe despite recommendations that tenofovir (TDF) + lamivudine (3TC) is the most effective nucleoside/nucleotide reverse transcriptase inhibitor (NRTI) backbone of antiretroviral therapy (ART) in those with dual infection. Objective To determine 1) numbers screened for hepatitis B surface antigen (HBsAg); 2) numbers diagnosed HBsAg-positive along with baseline characteristics; and 3) NRTI backbones used among PLHIV initiating first-line ART at Mpilo Opportunistic Infections Clinic, Bulawayo, Zimbabwe, between October 2017 and April 2019. Design This was a cross-sectional study using routinely collected data. Results Of the 422 PLHIV initiating first-line ART (median age 34 years, IQR 25-43), 361 (85%) were screened for HBV, with 10% being HBsAg-positive. HBsAg positivity was significantly associated with anaemia (adjusted prevalence ratio [aPR] 2.3, 95%CI 1.1-4.7) and elevated ala-nine transaminase levels (aPR 2.9, 95%CI 1.5-5.8). Of 38 PLHIV who were diagnosed HBsAg-positive, 30 (79%) were started on ART based on tenofovir (TDF) and lamivudine (3TC), seven were given abacavir (ABC) + 3TC-based ART and one was given zido vudine (ZDV) + 3TC-based ART. Conclusion In PLHIV, HBV screening worked well, the prevalence of HIV-HBV co-infection was high and most patients received appropriate treatment for both conditions. Recommendations to improve screening, diagnosis and treatment of HIV-HBV co-infection are discussed.

Abstract
Patients with drug-resistant tuberculosis (DR-TB) have received community-based care in Eswatini since 2009. Trained and compensated community treatment supporters (CTSs) provide directly observed therapy (DOT), injectables and psychological support. We examined the acceptability of this model of care among DR-TB patients, including the perspective of family members of DR-TB patients and their CTSs in relation to the patient's experience of care and quality of life. This qualitative research was conducted in rural Eswatini in February 2018. DR-TB patients, CTSs and family members participated in in-depth interviews, paired interviews, focus group discussions and PhotoVoice. Data were thematically analysed and coded, and themes were extracted. Methodological triangulation enhanced the interpretation. All patients and CTSs and most family members considered community-based DR-TB care to be supportive. Positive aspects were emotional support, trust and dedicated individual care, including enabling practical, financial and social factors. Concerns were related to social and economic problems within the family and fears about infection risks for the family and the CTSs. Community-based DR-TB care was acceptable to patients, family members and CTSs. To reduce family members' fears of TB infection, information and sensitisation within the family and constant follow-up appear crucial.

Abstract
Background To compare the histologic diagnosis of lesions associated with impacted teeth from a South African population with literature data. Material and Methods A retrospective cross-sectional survey of tissue specimens associated with impacted teeth that were analyzed in the Department of Oral Pathology (University of the Witwatersrand, South Africa) between 1996 and 2016. Patient age, gender, impacted tooth location and the histologic diagnosis were recorded for statistical analysis. Results Odontogenic pathology was diagnosed in 389 (95.6%) specimens while dental follicle comprised 4.4% of tissue submissions. The mean age was 25.3 ±15.2 years with a male predilection (M:F=1.8:1). The 11-20 year age group was mostly affected and the overall frequency of odontogenic lesions reduced significantly with an increase in age (p=0.01). Dentigerous cyst (56.5%) and ameloblastoma (14%) were most commonly diagnosed. Conclusions This is the first African epidemiologic survey of histologic specimens associated with impacted teeth and shows striking differences in the ratio of pathologic to non-pathologic diagnoses compared to other populations. Locally aggressive odontogenic lesions appear to develop one to two decades earlier in patients from developing countries. Key words:Ameloblastoma, biopsy, dentigerous cyst, histopathology, odontogenic cyst, odontogenic tumor.

Abstract
Objectives Provision of drug‐resistant tuberculosis (DR‐TB) treatment is scarce in resource‐limited settings. We assessed the feasibility of ambulatory DR‐TB care for treatment expansion in rural Eswatini. Methods Retrospective patient‐level data were used to evaluate ambulatory DR‐TB treatment provision in rural Shiselweni (Eswatini), from 2008 to 2016. DR‐TB care was either clinic‐based led by nurses or community‐based at the patient's home with involvement of community treatment supporters for provision of treatment to patients with difficulties in accessing facilities. We describe programmatic outcomes and used multivariate flexible parametric survival models to assess time to adverse outcomes. Both care models were costed in supplementary analyses. Results Of 698 patients initiated on DR‐TB treatment, 57% were women and 84% were HIV‐positive. Treatment initiations increased from 27 in 2008 to 127 in 2011 and decreased thereafter to 51 in 2016. Proportionally, community‐based care increased from 19% in 2009 to 77% in 2016. Treatment success was higher for community‐based care (79%) than clinic‐based care (68%, P = 0.002). After adjustment for covariate factors among adults (n = 552), the risk of adverse outcomes (death, loss to follow‐up, treatment failure) in community‐based care was reduced by 41% (adjusted hazard ratio 0.59, 95% CI: 0.39–0.91). Findings were supported by sensitivity analyses. The care provider's per‐patient costs for community‐based (USD13 345) and clinic‐based (USD12 990) care were similar. Conclusions Ambulatory treatment outcomes were good, and community‐based care achieved better treatment outcomes than clinic‐based care at comparable costs. Contextualised DR‐TB care programmes are feasible and can support treatment expansion in rural settings.

Abstract
OBJECTIVE To study the timing of pre-labour spontaneous rupture of membranes (SROM) in term pregnancies. DESIGN Prospective cohort. SETTING A maternity hospital in the United Kingdom. SAMPLE Women who were more than 37 weeks gestation with confirmed spontaneous rupture of membranes and not in labour after 4 h. METHODS Women who were admitted into labour ward with a diagnosis of spontaneous rupture of membranes after 37 weeks of gestation were included. The women's demographic details were recorded and inquiries about whether they had sexual intercourse in the preceding 12 h. The final outcome of their pregnancy was recorded and analysed. MAIN OUTCOME MEASURES (1) The exact time of spontaneous rupture of membranes, (2) the time of onset of spontaneous labour, (3) delivery details. RESULTS One hundred and ninety-six women were studied. A 24 h rhythm in the timing of spontaneous rupture of membranes was found with 33.2% occurring between 00:00 and 04:00 h. When contractions representing the onset of labour occurred there was no diurnal rhythm to the timing of onset of contractions. CONCLUSIONS There is a 24 h rhythm in the timing of spontaneous rupture of membranes in term gestations. The physiological reasons for this rhythm are not understood at the present time.
