Abstract
BACKGROUND Sodium-glucose co-transporter-2 (SGLT2) inhibitors reduce progression of chronic kidney disease and the risk of cardiovascular morbidity and mortality in a wide range of patients. However, their effects on kidney disease progression in some patients with chronic kidney disease are unclear because few clinical kidney outcomes occurred among such patients in the completed trials. In particular, some guidelines stratify their level of recommendation about who should be treated with SGLT2 inhibitors based on diabetes status and albuminuria. We aimed to assess the effects of empagliflozin on progression of chronic kidney disease both overall and among specific types of participants in the EMPA-KIDNEY trial. METHODS EMPA-KIDNEY, a randomised, controlled, phase 3 trial, was conducted at 241 centres in eight countries (Canada, China, Germany, Italy, Japan, Malaysia, the UK, and the USA), and included individuals aged 18 years or older with an estimated glomerular filtration rate (eGFR) of 20 to less than 45 mL/min per 1·73 m2, or with an eGFR of 45 to less than 90 mL/min per 1·73 m2 with a urinary albumin-to-creatinine ratio (uACR) of 200 mg/g or higher. We explored the effects of 10 mg oral empagliflozin once daily versus placebo on the annualised rate of change in estimated glomerular filtration rate (eGFR slope), a tertiary outcome. We studied the acute slope (from randomisation to 2 months) and chronic slope (from 2 months onwards) separately, using shared parameter models to estimate the latter. Analyses were done in all randomly assigned participants by intention to treat. EMPA-KIDNEY is registered at ClinicalTrials.gov, NCT03594110. FINDINGS Between May 15, 2019, and April 16, 2021, 6609 participants were randomly assigned and then followed up for a median of 2·0 years (IQR 1·5-2·4). Prespecified subgroups of eGFR included 2282 (34·5%) participants with an eGFR of less than 30 mL/min per 1·73 m2, 2928 (44·3%) with an eGFR of 30 to less than 45 mL/min per 1·73 m2, and 1399 (21·2%) with an eGFR 45 mL/min per 1·73 m2 or higher. Prespecified subgroups of uACR included 1328 (20·1%) with a uACR of less than 30 mg/g, 1864 (28·2%) with a uACR of 30 to 300 mg/g, and 3417 (51·7%) with a uACR of more than 300 mg/g. Overall, allocation to empagliflozin caused an acute 2·12 mL/min per 1·73 m2 (95% CI 1·83-2·41) reduction in eGFR, equivalent to a 6% (5-6) dip in the first 2 months. After this, it halved the chronic slope from -2·75 to -1·37 mL/min per 1·73 m2 per year (relative difference 50%, 95% CI 42-58). The absolute and relative benefits of empagliflozin on the magnitude of the chronic slope varied significantly depending on diabetes status and baseline levels of eGFR and uACR. In particular, the absolute difference in chronic slopes was lower in patients with lower baseline uACR, but because this group progressed more slowly than those with higher uACR, this translated to a larger relative difference in chronic slopes in this group (86% [36-136] reduction in the chronic slope among those with baseline uACR <30 mg/g compared with a 29% [19-38] reduction for those with baseline uACR ≥2000 mg/g; ptrend<0·0001). INTERPRETATION Empagliflozin slowed the rate of progression of chronic kidney disease among all types of participant in the EMPA-KIDNEY trial, including those with little albuminuria. Albuminuria alone should not be used to determine whether to treat with an SGLT2 inhibitor. FUNDING Boehringer Ingelheim and Eli Lilly.

Abstract
BACKGROUND The EMPA-KIDNEY trial showed that empagliflozin reduced the risk of the primary composite outcome of kidney disease progression or cardiovascular death in patients with chronic kidney disease mainly through slowing progression. We aimed to assess how effects of empagliflozin might differ by primary kidney disease across its broad population. METHODS EMPA-KIDNEY, a randomised, controlled, phase 3 trial, was conducted at 241 centres in eight countries (Canada, China, Germany, Italy, Japan, Malaysia, the UK, and the USA). Patients were eligible if their estimated glomerular filtration rate (eGFR) was 20 to less than 45 mL/min per 1·73 m2, or 45 to less than 90 mL/min per 1·73 m2 with a urinary albumin-to-creatinine ratio (uACR) of 200 mg/g or higher at screening. They were randomly assigned (1:1) to 10 mg oral empagliflozin once daily or matching placebo. Effects on kidney disease progression (defined as a sustained ≥40% eGFR decline from randomisation, end-stage kidney disease, a sustained eGFR below 10 mL/min per 1·73 m2, or death from kidney failure) were assessed using prespecified Cox models, and eGFR slope analyses used shared parameter models. Subgroup comparisons were performed by including relevant interaction terms in models. EMPA-KIDNEY is registered with ClinicalTrials.gov, NCT03594110. FINDINGS Between May 15, 2019, and April 16, 2021, 6609 participants were randomly assigned and followed up for a median of 2·0 years (IQR 1·5-2·4). Prespecified subgroupings by primary kidney disease included 2057 (31·1%) participants with diabetic kidney disease, 1669 (25·3%) with glomerular disease, 1445 (21·9%) with hypertensive or renovascular disease, and 1438 (21·8%) with other or unknown causes. Kidney disease progression occurred in 384 (11·6%) of 3304 patients in the empagliflozin group and 504 (15·2%) of 3305 patients in the placebo group (hazard ratio 0·71 [95% CI 0·62-0·81]), with no evidence that the relative effect size varied significantly by primary kidney disease (pheterogeneity=0·62). The between-group difference in chronic eGFR slopes (ie, from 2 months to final follow-up) was 1·37 mL/min per 1·73 m2 per year (95% CI 1·16-1·59), representing a 50% (42-58) reduction in the rate of chronic eGFR decline. This relative effect of empagliflozin on chronic eGFR slope was similar in analyses by different primary kidney diseases, including in explorations by type of glomerular disease and diabetes (p values for heterogeneity all >0·1). INTERPRETATION In a broad range of patients with chronic kidney disease at risk of progression, including a wide range of non-diabetic causes of chronic kidney disease, empagliflozin reduced risk of kidney disease progression. Relative effect sizes were broadly similar irrespective of the cause of primary kidney disease, suggesting that SGLT2 inhibitors should be part of a standard of care to minimise risk of kidney failure in chronic kidney disease.

Abstract
BACKGROUND Gut dysbiosis is implicated in colorectal cancer (CRC) pathogenesis. Cystic fibrosis (CF) is associated with both gut dysbiosis and increased CRC risk. We therefore compared the faecal microbiota from individuals with CF to CRC and screening samples. We also assessed changes in CRC-associated taxa before and after triple CF transmembrane conductance regulator (CFTR) modulator therapy. METHODS Bacterial DNA amplification comprising V4 16S rRNA analysis was conducted on 84 baseline and 53 matched follow-up stool samples from adults with CF. These data were compared to an existing cohort of 430 CRC and 491 control gFOBT samples from the NHS Bowel Cancer Screening Programme. Data were also compared to 26 previously identified CRC-associated taxa from a published meta-analysis. RESULTS Faecal CF samples had a lower alpha diversity and clustered distinctly from both CRC and control samples, with no clear clinical variables explaining the variation. Compared to controls, CF samples had an increased relative abundance in 6 of the 20 enriched CRC-associated taxa and depletion of 2 of the 6 taxa which have been reported as reduced in CRC. Commencing triple modulator therapy had subtle influence on the relative abundance of CRC-associated microbiota (n = 23 paired CF samples). CONCLUSIONS CF stool samples were clearly dysbiotic, clustering distinctly from both CRC and control samples. Several bacterial shifts in CF samples resembled those observed in CRC. Studies assessing the impact of dietary or other interventions and the longer-term use of CFTR modulators on reducing this potentially pro-oncogenic milieu are needed.

Abstract
INTRODUCTION Long-acting and extended delivery (LAED) regimens for HIV treatment and prevention offer unique benefits to expand uptake, effective use and adherence. To date, research has focused on basic and clinical science around the safety and efficacy of these products. This commentary outlines opportunities in HIV prevention and treatment programmes, both for the health system and clients, that could be addressed through the inclusion of LAED regimens and the vital role of differentiated service delivery (DSD) in ensuring efficient and equitable access. DISCUSSION The realities and challenges within HIV treatment and prevention programmes are different. Globally, more than 28 million people are accessing HIV treatment-the vast majority on a daily fixed-dose combination oral pill that is largely available, affordable and well-tolerated. Many people collect extended refills outside of health facilities with clinical consultations once or twice a year. Conversely, uptake of daily oral pre-exposure prophylaxis (PrEP) has consistently missed global targets due to limited access with high individual cost and lack of choice contributing to substantial unmet PrEP need. Recent trends in demedicalization, simplification, additional method options and DSD for PrEP have led to accelerated uptake as its availability has become more aligned with user preferences. How people currently receive HIV treatment and prevention services and their barriers to adherence must be considered for the introduction of LAED regimens to achieve the expected improvements in access and outcomes. Important considerations include the building blocks of DSD: who (provider), where (location), when (frequency) and what (package of services). Ideally, all LAED regimens will leverage DSD models that emphasize access at the community level and self-management. For treatment, LAED regimens may address challenges with adherence but their delivery should provide clear advantages over existing oral products to be scaled. For prevention, LAED regimens expand a potential PrEP user's choice of methods, but like other methods, need to be delivered in a manner that can facilitate frequent re-initiation. CONCLUSIONS To ensure that innovative LAED HIV treatment and prevention products reach those who most stand to benefit, service delivery and client considerations during development, trial and early implementation are critical.

Abstract
The coronavirus disease 2019 (COVID-19) pandemic led to a reordering of healthcare priorities. Health resources were turned to the screening and diagnosis of COVID-19, leading to a reduction in tuberculosis (TB) testing and treatment initiation. An innovative model that integrated TB and COVID-19 services was adopted at primary care facilities in Johannesburg Health District, Gauteng. This short report illustrates results from this model's implementation in two facilities. Patients were screened for COVID-19 at a single point of entry and separated according to screening result. Self-reported human immunodeficiency virus (HIV) status, symptom, and symptom duration were then used to determine TB risk amongst those screening positive for COVID-19. Data from clinical records were extracted. Approximately 9% of patients with a positive symptom screen (n = 76) were sent for a TB test and 84% were sent for a COVID-19 test. Amongst those sent for a TB test, 8% (n = 6) had TB detected, and amongst those sent for a COVID-19 test, 18% (n = 128) were positive. Amongst those with COVID-19-related symptoms, 15% (n = 130) presented with a cough or fever and were known HIV positive and 121 (93%) of these were sent for a COVID-19 test and 31 (24%) were sent for a TB test. Given the HIV prevalence and symptoms in our study, our results show lower-than-expected TB tests conducted.Contribution: Our study documents the outcomes of an innovative way to combine operational workflows for TB and COVID-19. This provides a starting point for countries seeking to integrate TB and COVID-19 screening and testing.

Abstract
BACKGROUND Incisional hernias cause morbidity and may require further surgery. HART (Hughes Abdominal Repair Trial) assessed the effect of an alternative suture method on the incidence of incisional hernia following colorectal cancer surgery. METHODS A pragmatic multicentre single-blind RCT allocated patients undergoing midline incision for colorectal cancer to either Hughes closure (double far-near-near-far sutures of 1 nylon suture at 2-cm intervals along the fascia combined with conventional mass closure) or the surgeon's standard closure. The primary outcome was the incidence of incisional hernia at 1 year assessed by clinical examination. An intention-to-treat analysis was performed. RESULTS Between August 2014 and February 2018, 802 patients were randomized to either Hughes closure (401) or the standard mass closure group (401). At 1 year after surgery, 672 patients (83.7 per cent) were included in the primary outcome analysis; 50 of 339 patients (14.8 per cent) in the Hughes group and 57 of 333 (17.1 per cent) in the standard closure group had incisional hernia (OR 0.84, 95 per cent c.i. 0.55 to 1.27; P = 0.402). At 2 years, 78 patients (28.7 per cent) in the Hughes repair group and 84 (31.8 per cent) in the standard closure group had incisional hernia (OR 0.86, 0.59 to 1.25; P = 0.429). Adverse events were similar in the two groups, apart from the rate of surgical-site infection, which was higher in the Hughes group (13.2 versus 7.7 per cent; OR 1.82, 1.14 to 2.91; P = 0.011). CONCLUSION The incidence of incisional hernia after colorectal cancer surgery is high. There was no statistical difference in incidence between Hughes closure and mass closure at 1 or 2 years.

Abstract
Abstract
Introduction
Research shows delivery of advance care planning (ACP) in care homes is highly acceptable, increases the proportion of residents dying in their preferred place, and reduces hospital admissions. We examined whether implementation of a service delivering ACP to care homes in Lincoln (UK) realised the research outcomes in routine practice.
Method
Implementation of a service undertaking ACP in care homes was evaluated using routine data. Outcomes included proportion of care homes agreeing to participate; proportion of residents agreeing to put ACPs in place; characteristics of residents with and without ACPs, and place of death of those dying with or without ACPs. Effect on hospital admissions was examined comparing pre- and post-implementation admissions in participating homes.
Results
Fifteen (63%) of 24 eligible care homes participated. ACPs were prepared for 404/516 (78%) residents. Those with ACPs were older, frailer, more cognitively impaired, and malnourished than those without. For those with ACPs (384/404; 95%), care homes were the preferred place of death. 219/248 (88%) of residents with ACPs who died did so in their care home compared to 33/49 who died without ACPs (33/49, (67%) (relative risk 1.35, 95%CI 1.1–1.6, p < 0.01). In the 15 participating homes, there were 717 hospital admissions over 360 pre-intervention care home months (mean 2.11 admissions per care home month). In the post intervention phase, there were 789 admissions over 341 care home months (mean 2.29 admissions per care home month).
Conclusion
Most residents wished to have ACPs, which appeared to have influenced place of death. However, the population value of the service was limited because not all care homes participated. Hospital admissions were not reduced. Future work should aim to ensure services are universally available to residents, and to identify why reductions in hospital admissions seen in research studies may not be replicated in clinical practice.

Abstract
INTRODUCTION In response to COVID-19, national ministries of health adapted HIV service delivery guidelines to ensure uninterrupted access to antiretroviral therapy (ART) and limit the frequency of contact with health facilities. In this commentary, we summarize four ways in which differentiated service delivery (DSD) for HIV treatment has been accelerated during COVID-19 in policy and implementation in sub-Saharan Africa (SSA) - (i) expanding eligibility for DSD for HIV treatment, (ii) extending multi-month dispensing (MMD) and reducing the frequency of clinical consultations, (iii) emphasizing community-based models and (iv) integrating/aligning with TB preventative therapy (TPT), non-communicable disease (NCD) treatments and family planning commodities. DISCUSSION Across SSA in 2020, countries both adapted and emphasized policies supporting DSD for HIV treatment in response to COVID-19. Access to DSD for HIV treatment was expanded by reducing the time required on ART before eligibility and being more inclusive of specific populations including children and adolescents, pregnant and breastfeeding women and those on second- and third-line regimens. Access to extended ART refills, or MMD, was accelerated across many countries. A renewed focus was given to out-of-facility community-based models of ART distribution. In some settings, there was acknowledgement of the need to integrate or align other chronic medications with ART. CONCLUSIONS Adaptations to DSD for HIV treatment in response to COVID-19 have resulted in rapid policy change and in some cases, acceleration of implementation in SSA. As the COVID-19 pandemic evolves, there is a critical need to assess the impact of these adaptations and, where beneficial, ensure that policies implemented in response to COVID-19 become the new normal.

Abstract
INTRODUCTION The antiretroviral therapy (ART) adherence club (AC) model has supported clinically stable HIV patients' retention with group ART refills and psychosocial support. Reducing visit frequency by increasing ART refills to six months could further benefit patients and unburden health systems. We conducted a pragmatic non-inferiority cluster randomized trial comparing standard of care (SoC) ACs and six-month refill intervention ACs in a primary care facility in Khayelitsha, South Africa. METHODS Existing community-based and facility-based ACs were randomized to either SoC or intervention ACs. SoC ACs met five times annually, receiving two-month refills with a four-month refill over year-end. Blood was drawn at one AC visit with a clinical assessment at the next. Intervention ACs met twice annually receiving six-month refills, with an individual blood collection visit before the annual clinical assessment AC visit. The first study visits were in October and November 2017 and participants followed for 27 months. We report retention in care, viral load completion and viral suppression (<400 copies/mL) 24 months after enrolment and calculated intention-to-treat risk differences for the primary outcomes using generalized estimating equations specifying for clustering by AC. RESULTS Of 2150 participants included in the trial, 977 were assigned to the intervention arm (40 ACs) and 1173 to the SoC (48 ACs). Patient characteristics at enrolment were similar across groups. Retention in care at 24 months was similarly high in both arms: 93.6% (1098/1173) in SoC and 92.6% (905/977) in the intervention arm, with a risk difference of -1.0% (95% CI: -3.2 to 1.3). The intervention arm had higher viral load completion (90.8% (999/1173) versus 85.1% (887/977)) and suppression (87.3% (969 /1173) versus 82.6% (853/977)) at 24 months, with a risk difference for completion of 5.5% (95% CI: 1.5 to 9.5) and suppression of 4.6% (95% CI: 0.2 to 9.0). CONCLUSIONS Intervention AC patients receiving six-month ART refills showed non-inferior retention in care, viral load completion and viral load suppression to those in SoC ACs, adding to a growing literature showing good outcomes with extended ART dispensing intervals.

Abstract
IntroductionThe Promoting Activity, Independence and Stability in Early Dementia (PrAISED) is delivering an exercise programme for people with dementia. The Lincolnshire partnership NHS foundation Trust successfully delivered PrAISED through a video-calling platform during the COVID-19 pandemic.ObjectivesThis qualitative case-study identified participants that video delivery worked for, and highlighted its benefits and challenges.MethodsInterviews were conducted with participants with dementia, caregivers and therapists, and analysed through thematic analysis.ResultsVideo delivery worked best when participants had a supporting carer, when therapists showed enthusiasm and had an established rapport with the client. Benefits included time-efficiency of sessions, enhancing participants’ motivation, caregivers’ dementia awareness and therapists’ creativity. Limitations included users’ poor IT skills and resources.ConclusionsThe COVID-19 pandemic required innovative ways of delivering rehabilitation. This study supports that people with dementia can use tele rehab, but success is reliant on having a caregiver and an enthusiastic and known therapist.

Abstract
PURPOSE OF REVIEW Despite the significant progress in the HIV response, gaps remain in ensuring engagement in care to support life-long medication adherence and viral suppression. This review sought to describe the different points in the HIV care cascade where people living with HIV were not engaging and highlight promising interventions. RECENT FINDINGS There are opportunities to improve engagement both between testing and treatment and to support re-engagement in care for those in a treatment interruption. The gap between testing and treatment includes people who know their HIV status and people who do not know their status. People in a treatment interruption include those who interrupt immediately following initiation, early on in their treatment (first 6 months) and late (after 6 months or more on ART). For each of these groups, specific interventions are required to support improved engagement. There are diverse needs and specific populations of people living with HIV who are not engaged in care, and differentiated service delivery interventions are required to meet their needs and expectations. For the HIV response to realise the 2030 targets, engagement will need to be supported by quality care and patient choice combined with empowered patients who are treatment literate and have been supported to improve self-management.

Abstract
OBJECTIVE Longer intervals between routine clinic visits and medication refills are part of patient-centred, differentiated service delivery (DSD). They have been shown to improve patient outcomes as well as optimise health services-vital as 'universal test-and-treat' targets increase numbers of HIV patients on antiretroviral treatment (ART). This qualitative study explored patient, healthcare worker and key informant experiences and perceptions of extending ART refills to 6 months in adherence clubs in Khayelitsha, South Africa. DESIGN AND SETTING In-depth interviews were conducted in isiXhosa with purposively selected patients and in English with healthcare workers and key informants. All transcripts were audio-recorded, transcribed and translated to English, manually coded and thematically analysed. The participants had been involved in a randomised controlled trial evaluating multi-month ART dispensing in adherence clubs, comparing 6-month and 2-month refills. PARTICIPANTS Twenty-three patients, seven healthcare workers and six key informants. RESULTS Patients found that 6-month refills increased convenience and reduced unintended disclosure. Contrary to key informant concerns about patients' responsibility to manage larger quantities of ART, patients receiving 6-month refills were highly motivated and did not face challenges transporting, storing or adhering to treatment. All participant groups suggested that strict eligibility criteria were necessary for patients to realise the benefits of extended dispensing intervals. Six-month refills were felt to increase health system efficiency, but there were concerns about whether the existing drug supply system could adapt to 6-month refills on a larger scale. CONCLUSIONS Patients, healthcare workers and key informants found 6-month refills within adherence clubs acceptable and beneficial, but concerns were raised about the reliability of the supply chain to manage extended multi-month dispensing. Stepwise, slow expansion could avoid overstressing supply and allow time for the health system to adapt, permitting 6-month ART refills to enhance current DSD options to be more efficient and patient-centred within current health system constraints.

Abstract
BACKGROUND The antiretroviral therapy (ART) adherence club (AC) differentiated service delivery model, where clinically stable ART patients receive their ART refills and psychosocial support in groups has supported clinically stable patients' retention and viral suppression. Patients and health systems could benefit further by reducing visit frequency and increasing ART refills. We designed a cluster-randomized control trial comparing standard of care (SoC) ACs and six-month ART refill (Intervention) ACs in a large primary care facility in Khayelitsha, South Africa. METHODS Existing ACs were randomized to either the control (SOC ACs) or intervention (Intervention ACs) arm. SoC ACs meet five times annually, receiving two-month ART refills with a four-month ART refill over year-end. Blood is drawn at the AC visit ahead of the clinical assessment visit. Intervention ACs meet twice annually receiving six-month ART refills, with a third individual visit for routine blood collection anytime two-four weeks before the annual clinical assessment AC visit. Primary outcomes will be retention in care, annual viral load assessment completion and viral load suppression. (<400copies/mL) after 2 years. Ethics approval has been granted by the University of Cape Town (HREC 652/2016) and the Medecins Sans Frontieres (MSF) Ethics Review Board (#1639). Results will be published in peer-reviewed journals and made widely available through presentations and briefing documents. DISCUSSION Evaluation of an extended ART refill interval in adherence clubs will provide evidence towards novel model adaptions that can be made to further improve convenience for patients and leverage health system efficiencies.

Abstract
Background Globally, 37 million people are in need of lifelong antiretroviral treatment (ART). With the continual increase in the number of people living with HIV starting ART and the need for life-long retention and adherence, increasing attention is being paid to differentiated service delivery (DSD), such as adherence clubs. Adherence clubs are groups of 25–30 stable ART patients who meet five times per year at their clinic or a community location and are facilitated by a lay health-care worker who distributes pre-packed ART. This qualitative study explores patient experiences of clubs in two sites in Cape Town, South Africa. Methods A total of 144 participants took part in 11 focus group discussions (FGDs) and 56 in-depth interviews in the informal settlements of Khayelitsha and Gugulethu in Cape Town, South Africa. Participants included current club members, stable patients who had never joined a club and club members referred back to clinician-led facility-based standard care. FGDs and interviews were conducted in isiXhosa, translated and transcribed into English, entered into NVivo, coded and thematically analysed. Results The main themes were 1) understanding and knowledge of clubs; 2) understanding of and barriers to enrolment; 3) perceived benefits and 4) perceived disadvantages of the clubs. Participants viewed membership as an achievement and considered returning to clinician-led care a ‘failure’. Moving between clubs and the clinic created frustration and broke down trust in the health-care system. Conclusions Adherence clubs were appreciated by patients, particularly time-saving in relation to flexible ART collection. Improved patient understanding of enrolment processes, eligibility and referral criteria and the role of clinical oversight is essential for building relationships with health-care workers and trust in the health-care system.

Abstract
Background Eligibility for differentiated antiretroviral therapy (ART) delivery models has to date been limited to low-risk stable patients. Objectives We examined the outcomes of patients who accessed their care and treatment through an ART adherence club (AC), a differentiated ART delivery model, immediately following receiving support to achieve viral suppression after experiencing elevated viral loads (VLs) at a high-burden ART clinic in Khayelitsha, South Africa. Methods Beginning in February 2012, patients with VLs above 400 copies/mL either on first- or second-line regimens received a structured intervention developed for patients at risk of treatment failure. Patients who successfully suppressed either on the same regimen or after regimen switch were offered immediate enrolment in an AC facilitated by a lay community health worker. We conducted a retrospective cohort analysis of patients who enrolled in an AC directly after receiving suppression support. We analysed outcomes (retention in care, retention in AC care and viral rebound) using Kaplan–Meier methods with follow-up from October 2012 to June 2015. Results A total of 165 patients were enrolled in an AC following suppression (81.8% female, median age 36.2 years). At the closure of the study, 119 patients (72.0%) were virally suppressed and 148 patients (89.0%) were retained in care. Six, 12 and 18 months after AC enrolment, retention in care was estimated at 98.0%, 95.0% and 89.0%, respectively. Viral suppression was estimated to be maintained by 90.0%, 84.0% and 75.0% of patients at 6, 12 and 18 months after AC enrolment, respectively. Conclusion Our findings suggest that patients who struggled to achieve or maintain viral suppression in routine clinic care can have good retention and viral suppression outcomes in ACs, a differentiated ART delivery model, following suppression support.

Abstract
AIM To investigate the effect of image processing on cancer detection in mammography. METHODS AND MATERIALS An observer study was performed using 349 digital mammography images of women with normal breasts, calcification clusters, or soft-tissue lesions including 191 subtle cancers. Images underwent two types of processing: FlavourA (standard) and FlavourB (added enhancement). Six observers located features in the breast they suspected to be cancerous (4,188 observations). Data were analysed using jackknife alternative free-response receiver operating characteristic (JAFROC) analysis. Characteristics of the cancers detected with each image processing type were investigated. RESULTS For calcifications, the JAFROC figure of merit (FOM) was equal to 0.86 for both types of image processing. For soft-tissue lesions, the JAFROC FOM were better for FlavourA (0.81) than FlavourB (0.78); this difference was significant (p=0.001). Using FlavourA a greater number of cancers of all grades and sizes were detected than with FlavourB. FlavourA improved soft-tissue lesion detection in denser breasts (p=0.04 when volumetric density was over 7.5%) CONCLUSIONS: The detection of malignant soft-tissue lesions (which were primarily invasive) was significantly better with FlavourA than FlavourB image processing. This is despite FlavourB having a higher contrast appearance often preferred by radiologists. It is important that clinical choice of image processing is based on objective measures.

Abstract
OBJECTIVE The ambitious '90-90-90' treatment targets require innovative models of care to support quality antiretroviral therapy (ART) delivery. While evidence for differentiated models of ART delivery is growing, there are few data on the feasibility of scale-up. We describe the implementation of the Adherence Club (AC) model across the Cape Metro health district in Cape Town, South Africa, between January 2011 and March 2015. METHODS Using data from monthly aggregate AC monitoring reports and electronic monitoring systems for the district cohort, we report on the number of facilities offering ACs and the number of patients receiving ART care in the AC model. RESULTS Between January 2011 and March 2015, the AC programme expanded to reach 32 425 patients in 1308 ACs at 55 facilities. The proportion of the total ART cohort retained in an AC increased from 7.3% at the end of 2011 to 25.2% by March 2015. The number of facilities offering ACs also increased and by the end of the study period, 92.3% of patients were receiving ART at a facility that offered ACs. During this time, the overall ART cohort doubled from 66 616 to 128 697 patients. The implementation of the AC programme offset this increase by 51%. CONCLUSIONS ACs now provide ART care to more than 30 000 patients. Further expansion of the model will require additional resources and support. More research is necessary to determine the outcomes and quality of care provided in ACs and other differentiated models of ART delivery, especially when implemented at scale.

Abstract
OBJECTIVE Women with diabetes may need elective preterm delivery due to pregnancy or diabetes related complications. The aim of this study was to describe the neonatal outcomes arising from elective preterm delivery in diabetic women. METHOD Suitable patients were identified by the obstetric team at Hull Royal Infirmary Women and Children's Hospital and data was extracted from their case notes. 45 diabetic women with planned preterm delivery were identified within a set time frame, resulting in 48 babies. RESULTS Of the 48 babies born, 47 survived. 36 out of 48 were delivered via caesarean section. Gestational ages ranged from 29+3 to 36+6 weeks, and 24 out of 48 (50%) had a birth weight greater than the 90th centile for gestational age.34 out of the 48 babies experienced some form of neonatal complication and were admitted to the neonatal unit. The median duration of stay in the neonatal unit was 7 days. 14 of the surviving neonates suffered from respiratory distress, although only 4 required surfactant therapy to regain respiratory function. However, the incidence of serious neonatal complications in those born after 34 weeks was shown to be low. CONCLUSIONS Elective preterm delivery after 34 weeks had little effect on overall neonatal outcome. Therefore it could be proposed that elective preterm delivery after 34 weeks gestation may be an acceptable option in diabetic women if there are maternal or obstetric complications.

Abstract
Background Although mortality from breast cancer is declining, incidence continues to increase and is often detected at routine NHS screening. Most middle aged and older women in England attend for screening every 3 years. Assessing their personal breast cancer risk and providing preventative lifestyle advice could help to further reduce breast cancer incidence. Methods A cross-sectional, self-complete postal survey measured attendees' interest in having a personal risk assessment, expected impact on screening attendance, knowledge of associations between lifestyle and breast cancer and preferred ways of accessing preventative lifestyle advice. Results A total of 1803/4948 (36.4%) completed questionnaires were returned. Most participants (93.7%) expressed interest in a personal risk assessment and 95% (1713/1803) believed it would make no difference or encourage re-attendance. Two-thirds (1208/1803) associated lifestyle with breast cancer, but many were unaware of specific risks such as weight gain, obesity, alcohol consumption and physical inactivity. NHS sourced advice was expected to be more credible than other sources, and booklets, brief counselling or an interactive website were most preferred for accessing this. Conclusions Attendees appear to welcome an intervention that would facilitate more proactive clinical and lifestyle prevention and address critical research gaps in breast cancer prevention and early detection.

Abstract
Empirical evidence suggests that levodopa medication used to treat the motor symptoms of Parkinson's disease (PD) may either improve, impair or not affect specific cognitive processes. This evidence led to the 'dopamine overdose' hypothesis that levodopa medication impairs performance on cognitive tasks if they recruit fronto-striatal circuits which are not yet dopamine-depleted in early PD and as a result the medication leads to an excess of dopamine. This hypothesis has been supported for various learning tasks including conditional associative learning, reversal learning, classification learning and intentional deterministic sequence learning, on all of which PD patients demonstrated significantly worse performance when tested on relative to off dopamine medication. Incidental sequence learning is impaired in PD, but how such learning is affected by dopaminergic therapy remains undetermined. The aim of the current study was to investigate the effect of dopaminergic medication on incidental sequence learning in PD. We used a probabilistic serial reaction time task (SRTT), a sequence learning paradigm considered to make the sequence less apparent and more likely to be learned incidentally rather than intentionally. We compared learning by the same group of PD patients (n=15) on two separate occasions following oral administration of levodopa medication (on state) and after overnight withdrawal of medication (off state). Our results demonstrate for the first time that levodopa medication enhances incidental learning of a probabilistic sequence on the serial reaction time task in PD. However, neither group significantly differed from performance of a control group without a neurological disease, which indicates the importance of within group comparisons for identifying deficits. Levodopa medication enhanced incidental learning by patients with PD on a probabilistic sequence learning paradigm even though the patients were not aware of the existence of the sequence or their acquired knowledge. The results suggest a role in acquiring incidental motor sequence learning for dorsal striatal areas strongly affected by dopamine depletion in early PD.

Abstract
BACKGROUND The World Health Organization recommends tuberculin skin tests (TSTs) where feasible to identify individuals most likely to benefit from isoniazid preventive therapy (IPT). The requirement for TST reading after 48-72 h by a trained nurse is a barrier to implementation and increases loss to follow-up. METHODS Patients with human immunodeficiency virus (HIV) infection were recruited from a primary care clinic in South Africa and trained by a lay counsellor to interpret their own TST. The TST was placed by a nurse, and the patient was asked to return 2 days later with their self-reading result, followed by blinded reading by a trained nurse (reference). RESULTS Of 227 patients, 210 returned for TST reading; 78% interpreted their test correctly: those interpreting it as negative were more likely to be correct (negative predictive value 93%) than those interpreting it as positive (positive predictive value 42%); 10/36 (28%) positive TST results were read as negative by the patient. CONCLUSIONS Patients with HIV in low-resource settings can be trained to interpret their own TST. Those interpreting it as positive should return to the clinic within 48-72 h for confirmatory reading and IPT initiation; those with a negative interpretation can return at their next scheduled visit and initiate IPT at that time if appropriate.

Abstract
OBJECTIVES As the scale of the South African HIV epidemic calls for innovative models of care that improve accessibility for patients while overcoming chronic human resource shortages, we (i) assess the cost-effectiveness of lay health worker-led group adherence clubs, in comparison with a nurse-driven 'standard of care' and (ii) describe and evaluate the associated patient cost and accessibility differences. METHODS Our cost-effectiveness analysis compares an 'adherence club' innovation to conventional nurse-driven care within a busy primary healthcare setting in Khayelitsha, South Africa. In each alternative, we calculate provider costs and estimate rates of retention in care and viral suppression as key measures of programme effectiveness. All results are presented on an annual or per patient-year basis. In the same setting, a smaller sample of patients was interviewed to understand the direct and indirect non-healthcare cost and access implications of the alternatives. Access was measured using McIntyre and colleagues' 2009 framework. RESULTS Adherence clubs were the more cost-effective model of care, with a cost per patient-year of $300 vs. $374 and retention in care at 1 year of 98.03% (95% CI 97.67-98.33) for clubs vs. 95.49% (95% CI 95.01-95.94) for standard of care. Viral suppression in clubs was 99.06% (95% CI 98.82-99.27) for clubs vs. 97.20% (95% CI 96.81-97.56) for standard of care. When interviewed, club patients reported fewer missed visits, shorter waiting times and higher acceptability of services compared to standard of care. CONCLUSIONS Adherence clubs offer the potential to enhance healthcare efficiency and patient accessibility. Their scale-up should be supported.

Abstract
INTRODUCTION Médecins Sans Frontières supports human immunodeficiency virus (HIV)-infected youth, aged 12-25 years, at a clinic in Khayelitsha, South Africa. Patients are enrolled in youth clubs, and provided with a virtual chat room, using the cell-phone-based social networking platform, MXit, to support members between monthly/bimonthly club meetings. The acceptability and uptake of MXit was assessed. METHODS MXit was facilitated by lay counsellors, was password protected, and participants could enter and leave at will. Club members were asked to complete self-administered questionnaires and participate in two focus-group discussions. RESULTS AND DISCUSSION In total, 60 club members completed the questionnaire, and 12 participated in the focus groups. Fifty-eight percentage were aged 23-25 years, 63% were female and 83% had a cell phone. Sixty percentage had used MXit before, with 38% having used it in the past month. Sixty-five percentage were aware of the chat-room and 39% knew how to access it. Thirty-four percentage used the chat-room at least once, 20% had visited the chat-room in the past month, and 29% had used MXit to have private conversations with other club members. Fifty-seven percentage used the chat-room to get advice, and 84% of all respondents felt that offering a service outside the youth club meetings was important and would like to see one to continue. The cost of using social media platforms was an issue with some, as well as the need for anonymity. Preference for other platforms, logistical obstacles, or loss of interest contributed to non-use. CONCLUSIONS Reported usage of the MXit chat-room was low, but participants indicated acceptance of the programme and their desire to interact with their peers through social media. Suggestions to improve the platform included accessible chat histories, using more popular platforms such as Facebook or WhatsApp, and to have topical discussions where pertinent information for youth is provided.

Abstract
SETTING South Africa is one of the world's 22 high tuberculosis (TB) burden countries, with the second highest number of notified rifampicin-resistant TB (R(R)-TB) and multidrug-resistant TB (MDR-TB) cases. OBJECTIVE To estimate patient costs associated with the diagnosis and treatment of R(R)-TB/MDR-TB in South Africa. DESIGN Patients diagnosed with R(R)-TB/MDR-TB and accessing care at government health care facilities were surveyed using a structured questionnaire. Direct and indirect costs associated with accessing R(R)-TB/MDR-TB care were estimated at different treatment durations for each patient. RESULTS A total of 134 patients were surveyed: 84 in the intensive phase and 50 in the continuation phase of treatment, 82 in-patients and 52 out-patients. The mean monthly patient costs associated with the diagnosis and treatment of R(R)-TB/MDR-TB were higher during the intensive phase than the continuation phase (US$235 vs. US$188) and among in-patients than among out-patients (US$269 vs. US$122). Patients in the continuation phase and those accessing care as out-patients reported higher out-of-pocket costs than other patients. Most patients did not access social protection for costs associated with R(R)-TB/MDR-TB illness. CONCLUSION Despite free health care, patients bear high costs when accessing diagnosis and treatment services for R(R)-TB/MDR-TB; appropriate social protection mechanisms should be provided to assist them in coping with these costs.

Abstract
BACKGROUND AND AIMS In 2010, demand on the Auckland City Hospital general medical service exceeded capacity. A review by the Royal Australasian College of Physicians was critical of training offered to registered medical officers, and low morale was a problem across the service. Management offered support for an improved model that would solve these problems. METHODS A project to redesign the general medical service was undertaken. Baseline analysis found uneven workload and insufficient capacity at peak times for patient presentations. Workshops involving the entire service led to a new model that splits workload and teams into patients likely to have a short stay from those requiring longer, ward-based care. Admissions are now distributed over 12 teams on weekdays and 4 on the weekends. There was an increase of approximately 2.5 in consultant full time equivalents but no change in registrar or house officer staffing. RESULTS Since the introduction of the new model, the average length of stay has fallen from 3.7 to 3.2 days (14%) and the median length of stay by 28%, resulting in a saving of 6000 bed days per year. Readmission, inpatient and 30-day mortality rates are unchanged. These results have been sustained over 18 months with signs of continuing improvement. CONCLUSION This project owes its success to the following factors - management support; iterative engagement of a range of staff; provision of timely data analysis; increases in senior medical officer staffing and reorganisation leading to more predictable and fair work practices. One challenge is discontinuity, whether between doctors and patients or within the medical team.

Abstract
Background Lengthy antiretroviral treatment (ART) preparation contributes to high losses to care between communicating ART eligibility and initiating ART. To address this shortfall, Médecins Sans Frontières implemented a revised approach to ART initiation counselling preparation (integrated for TB co-infected patients), shifting the emphasis from pre-initiation sessions to addressing common barriers to adherence and strengthening post-initiation support in a primary healthcare facility in Khayelitsha, South Africa. Methods An observational cohort study was conducted using routinely collected data for all ART-eligible patients attending their first counselling session between 23 July 2012 and 30 April 2013 to assess losses to care prior to and post ART initiation. Viral load completion and suppression rates of those retained on ART were also calculated. Results Overall, 449 patients enrolled in the study, of whom 3.6% did not return to the facility to initiate ART. Of those who were initiated, 96.7% were retained at their first ART refill visit and 85.9% were retained 6 months post ART initiation. Of those retained, 80.2% had a viral load taken within 6 months of initiating ART, with 95.4% achieving viral load suppression. Conclusions Adapting counselling to enable rapid ART initiation is feasible and has the potential to reduce losses to care prior to ART initiation without increasing short-term losses thereafter or compromising patient adherence.

Abstract
BACKGROUND South Africa has high burdens of HIV, TB and drug-resistant TB (DR-TB, rifampicin-resistance). Treatment outcome data for HIV-infected versus uninfected patients is limited. We assessed the impact of HIV and other factors on DR-TB treatment success, time to culture conversion, loss-from-treatment and overall mortality after second-line treatment initiation. METHODS A retrospective cohort analysis was conducted for patients initiated on DR-TB treatment from 2008 to 2012, within a community-based, decentralised programme in Khayelitsha, South Africa. RESULTS Among 853 confirmed DR-TB patients initiating second-line treatment, 605 (70.9%) were HIV infected. HIV status did not impact on time to sputum culture conversion nor did it impact treatment success; 48.1% (259/539) and 45.9% (100/218), respectively (p=0.59). In a multivariate model, HIV was not associated with treatment success. Death during treatment was higher among HIV-infected patients, but overall mortality was not significantly higher. HIV-infected patients with CD4 <=100 cells/ml were significantly more likely to die after starting treatment. CONCLUSIONS Response to DR-TB treatment did not differ with HIV infection in a programmatic setting with access to antiretroviral treatment (ART). Earlier ART initiation at a primary care level could reduce mortality among HIV-infected patients presenting with low CD4 counts.

Abstract
Objectives The high cost of rifampicin‐resistant tuberculosis (RR‐TB) treatment hinders treatment access. South Africa has a high RR‐TB burden, and national policy outlines decentralisation to improve access and reduce costs. We analysed health system costs associated with RR‐TB treatment by drug resistance profile and treatment outcome in a decentralised programme. Methods Retrospective, routinely collected patient‐level data were combined with unit cost data to determine costs for each patient in a cohort treated between January 2009 and December 2011. Drug costs were based on recommended regimens according to drug resistance and treatment duration. Hospitalisation costs were estimated based on admission/discharge dates, while clinic visit and diagnostic/monitoring costs were estimated according to recommendations and treatment duration. Missing data were imputed. Results Among 467 patients (72% HIV infected), 49% were successfully treated. Treatment was initiated in primary care for 62%, with the remainder as inpatients. The mean cost per patient treated was $7916 (range 260–87 140), ranging from $5369 among patients who did not complete treatment to $23 006 for treatment failure. Mean cost for successful treatment was $8359 (2585–32 506). Second‐line drug resistance was associated with a mean cost of $15 567 vs. $6852 for only first‐line resistance, with the major cost difference due to hospitalisation. Costs are reported in 2013 USD. Conclusions RR‐TB treatment cost was high and varied according to treatment outcome. Despite decentralisation, hospitalisation remained a significant cost, particularly among those with more extensive resistance and those with treatment failure. These cost estimates can be used to model the impact of new interventions to improve patient outcomes.

Abstract
The delivery of HIV care in the initial rapid scale-up of HIV care and treatment was based on existing clinic-based models, which are common in highly resourced settings and largely undifferentiated for individual needs. A new framework for treatment based on variable intensities of care tailored to the specific needs of different groups of individuals across the cascade of care is proposed here. Service intensity is characterised by four delivery components: (i) types of services delivered, (ii) location of service delivery, (iii) provider of health services and (iv) frequency of health services. How these components are developed into a service delivery framework will vary across countries and populations, with the intention being to improve acceptability and care outcomes. The goal of getting more people on treatment before they become ill will necessitate innovative models of delivering both testing and care. As HIV programmes expand treatment eligibility, many people entering care will not be 'patients' but healthy, active and productive members of society. To take the framework to scale, it will be important to: (i) define which individuals can be served by an alternative delivery framework; (ii) strengthen health systems that support decentralisation, integration and task shifting; (iii) make the supply chain more robust; and (iv) invest in data systems for patient tracking and for programme monitoring and evaluation.

Abstract
SETTING The cost of multidrug-resistant tuberculosis (MDR-TB) treatment is a major barrier to treatment scale-up in South Africa. OBJECTIVE To estimate and compare the cost of treatment for rifampicin-resistant tuberculosis (RR-TB) in South Africa in different models of care in different settings. DESIGN We estimated the costs of different models of care with varying levels of hospitalisation. These costs were used to calculate the total cost of treating all diagnosed cases of RR-TB in South Africa, and to estimate the budget impact of adopting a fully or partially decentralised model vs. a fully hospitalised model. RESULTS The fully hospitalised model was 42% more costly than the fully decentralised model (US$13,432 vs. US$7753 per patient). A much shorter hospital stay in the decentralised models of care (44-57 days), compared to 128 days of hospitalisation in the fully hospitalised model, was the key contributor to the reduced cost of treatment. The annual total cost of treating all diagnosed cases ranged from US$110 million in the fully decentralised model to US$190 million in the fully hospitalised model. CONCLUSION Following a more decentralised approach for treating RR-TB patients could potentially improve the affordability of RR-TB treatment in South Africa.

Abstract
OBJECTIVES Further scale-up of antiretroviral therapy (ART) to those in need while supporting the growing patient cohort on ART requires continuous adaptation of healthcare delivery models. We describe several approaches to manage stable patients on ART developed by Médecins Sans Frontières together with Ministries of Health in four countries in sub-Saharan Africa. METHODS Using routine programme data, four approaches to simplify ART delivery for stable patients on ART were assessed from a patient and health system perspective: appointment spacing for clinical and drug refill visits in Malawi, peer educator-led ART refill groups in South Africa, community ART distribution points in DRC and patient-led community ART groups in Mozambique. RESULTS All four approaches lightened the burden for both patients (reduced travel and lost income) and health system (reduced clinic attendance). Retention in care is high: 94% at 36 months in Malawi, 89% at 12 months in DRC, 97% at 40 months in South Africa and 92% at 48 months in Mozambique. Where evaluable, service provider costs are reported to be lower. CONCLUSION Separating ART delivery from clinical assessments was found to benefit patients and programmes in a range of settings. The success of community ART models depends on sufficient and reliable support and resources, including a flexible and reliable drug supply, access to quality clinical management, a reliable monitoring system and a supported lay workers cadre. Such models require ongoing evaluation and further adaptation to be able to reach out to more patients, including specific groups who may be challenged to meet the demands of frequent clinic visits and the integrated delivery of other essential chronic disease interventions.

Abstract
Maternal hypoxia is a common perturbation that can disrupt placental and thus fetal development, contributing to neonatal impairments. Recently, evidence has suggested that physiological outcomes are dependent upon the sex of the fetus, with males more susceptible to hypoxic insults than females. This study investigated the effects of maternal hypoxia during mid- to late gestation on fetal growth and placental development and determined if responses were sex specific. CD1 mice were housed under 21% or 12% oxygen from embryonic day (E) 14.5 until tissue collection at E18.5. Fetuses and placentas were weighed before collection for gene and protein expression and morphological analysis. Hypoxia reduced fetal weight in both sexes at E18.5 by 7% but did not affect placental weight. Hypoxia reduced placental mRNA levels of the mineralocorticoid and glucocorticoid receptors and reduced the gene and protein expression of the glucocorticoid metabolizing enzyme HSD11B2. However, placentas of female fetuses responded differently to maternal hypoxia than did placentas of male fetuses. Notably, morphology was significantly altered in placentas from hypoxic female fetuses, with a reduction in placental labyrinth blood spaces. In addition mRNA expression of Glut1, Igf2 and Igf1r were reduced in placentas of female fetuses only. In summary, maternal hypoxia altered placental formation in a sex specific manner through mechanisms involving placental vascular development, growth factor and nutrient transporter expression and placental glucocorticoid signalling. This study provides insight into how sex differences in offspring disease development may be due to sex specific placental adaptations to maternal insults.
