Key normative, legal, and policy considerations for supporting pregnant and postpartum adolescents in high HIV-burden settings: a critical analysis.

Rates of adolescent pregnancy within sub-Saharan Africa are increasing. Adolescent mothers ages 10-19 years face a distinct set of risks to their own and their children's health, compounded by many economic, social, and epidemiological challenges, such as living with HIV. In navigating this complex developmental period, many adolescent mothers face structural barriers impeding safe transitions to adulthood and motherhood. Drawing on existing literature and emerging data, we outline three normative, legal, and policy issues - violence and gender inequity, access to sexual and reproductive health services, and access to social and structural supports - which affect the health, wellbeing and development of adolescent mothers and their children. We also highlight emergent evidence about programming and policy changes that can better support adolescent mothers and their children. These key proposed responses include removing barriers to SRH and HIV service integration; ensuring implementation of return-to-school policies; and extending social protection systems to cater for adolescent mothers. Despite ongoing global crises and shifts in funding priorities, these normative, legal, and policy considerations remain critical to safeguard the health and wellbeing of adolescent mothers and their children.

Deficient butyrate-producing capacity in the gut microbiome is associated with bacterial network disturbances and fatigue symptoms in ME/CFS.

Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is characterized by unexplained debilitating fatigue, cognitive dysfunction, gastrointestinal disturbances, and orthostatic intolerance. Here, we report a multi-omic analysis of a geographically diverse cohort of 106 cases and 91 healthy controls that revealed differences in gut microbiome diversity, abundances, functional pathways, and interactions. Faecalibacterium prausnitzii and Eubacterium rectale, which are both recognized as abundant, health-promoting butyrate producers in the human gut, were reduced in ME/CFS. Functional metagenomics, qPCR, and metabolomics of fecal short-chain fatty acids confirmed a deficient microbial capacity for butyrate synthesis. Microbiome-based machine learning classifier models were robust to geographic variation and generalizable in a validation cohort. The abundance of Faecalibacterium prausnitzii was inversely associated with fatigue severity. These findings demonstrate the functional nature of gut dysbiosis and the underlying microbial network disturbance in ME/CFS, providing possible targets for disease classification and therapeutic trials.

Food security reduces multiple HIV infection risks for high-vulnerability adolescent mothers and non-mothers in South Africa: a cross-sectional study.

INTRODUCTION: Adolescent girls and young women, including adolescent mothers, in Southern Africa have high HIV seroconversion and transmission. We need to know which risks drive HIV infections, and what can reduce these risks. METHODS: We interviewed 1712 adolescent girls and young women (11-23 years), including 1024 adolescent mothers who had conceived before age 20 and had a living child, from two health municipalities of South Africa's Eastern Cape Province between March 2018 and July 2019. Recruitment was through multiple community, school and health facility channels. Associations between adolescent motherhood and seven HIV risk behaviours (multiple sexual partners, transactional sex, age-disparate sex, condomless sex, sex on substances, alcohol use and not in education or employment) were investigated using the generalized estimating equations method for multiple outcomes specified with a logit link and adjusting for nine covariates. Using the same model, we investigated associations between having enough food at home every day in the past week (food security) and the same seven HIV risk behaviours. When we found evidence of moderation by HIV status, we report stratum-specific odds ratios. RESULTS: Mean age was 17.51 years (SD: 2.54), 46% participants were living with HIV. Compared to non-mothers, adolescent mothers had lower odds of alcohol use (AOR = 0.47, 95% CI = 0.29-0.75), but higher odds of multiple sexual partners (AOR = 1.93, 95% CI = 1.35-2.74), age-disparate sex (HIV-uninfected AOR = 1.73, 95% CI = 1.03-2.91; living with HIV AOR = 5.10, 95% CI = 2.98-8.73), condomless sex (AOR = 8.20, 95% CI = 6.03-11.13), sex on substances (AOR = 1.88, 95% CI = 1.10-3.21) and not in education/employment (HIV-uninfected AOR = 1.83, 95% CI = 1.19-2.83; living with HIV AOR = 6.30, 95% CI = 4.09-9.69). Among non-mothers, food security was associated with lower odds of multiple sexual partners (AOR = 0.45, 95% CI = 0.26-0.78), transactional sex (AOR = 0.32, 95% CI = 0.13-0.82) and not in education/employment (AOR = 0.48, 95% CI = 0.29-0.77). Among adolescent mothers, food security was associated with lower odds of transactional sex (AOR = 0.17, 95% CI = 0.10-0.28), age-disparate sex (AOR = 0.66, 95% CI = 0.47-0.92), sex on substances (AOR = 0.51, 95% CI = 0.32-0.82), alcohol use (AOR = 0.45, 95% CI = 0.25-0.79) and not in education/employment (AOR = 0.56, 95% CI = 0.40-0.78). CONCLUSIONS: Adolescent motherhood is associated with multiple vulnerabilities to HIV infection and transmission. Social protection measures that increase food security are likely to reduce HIV risk pathways for adolescent girls and young women, especially adolescent mothers.

Consolidate, conceptualize, contextualise: key learnings for future intervention acceptability research with young people in Africa.

Acceptability has become a key consideration in the development, evaluation and implementation of health and social interventions. This commentary paper advances key learnings and recommendations for future intervention acceptability research with young people in Africa, aimed at supporting the achievement of developmental goals. It relates findings of the adolescent acceptability work conducted within the Accelerate Hub, since mid 2020, to broader inter-disciplinary literatures and current regional health and social priorities. We argue that, in order to strengthen the quality and applied value of future acceptability work with young people, we need to do three things better. First, we need to consolidate prior findings on acceptability, within and across intervention types, to inform responses to current public health and social challenges and further the conceptual work in this area. Second, we need to better conceptualise acceptability research with young people, by developing stronger conceptual frameworks that define acceptability and its constructs, and predict its relationship with intervention engagement. Third, we need to better contextualise findings by considering acceptability data within a broader social and political context, which in turn can be supported by better conceptualisation. In this paper we describe contributions of our work to each of these three inter-connected objectives, and suggest ways in which they may be taken forward by researchers and practitioners. These include aggregating evidence from past interventions to highlight potential barriers and enablers to current responses in priority areas; involving key actors earlier and more meaningfully in acceptability research; further developing and testing behavioural models for youth acceptability; and working collaboratively across sectors towards programmatic guidance for better contextualisation of acceptability research. Progress in this field will require an inter-disciplinary approach that draws from various literatures such as socio-ecological theory, political economy analysis, health behaviour models and literature on participatory research approaches.

Multiple Impacts of Ethiopia's Health Extension Program on Adolescent Health and Well-Being: A Quasi-Experimental Study 2002-2013.

PURPOSE: Ethiopia has registered remarkable achievements in reaching global development goals, including reducing child marriage. Policymakers are keen to understand which investments have contributed to this. We evaluated the association between Ethiopia's Health Extension Program (HEP) and 12 adolescent health and wellbeing outcomes. METHODS: We used Young Lives Ethiopia cohort data between 2002 and 2013. We evaluated associations between household support from HEP at age 15 and 12 adolescent outcomes spread across health, gender-based violence, education, and employment at age 19 using the inverse probability of treatment weighting propensity score approach, stratifying by sex. Adjusted probability differences (APDs) and adjusted mean differences (AMDs) were used to contrast exposure to HEP versus no exposure. RESULTS: Of 775 adolescents with complete follow-up, 46% were female. Sixty-six percent of adolescents reported support from HEP, with higher rates of support in poorer, less educated, and rural households, particularly in Tigray Province. In boys, HEP was positively associated with education enrolment (APD: +20 percentage points [ppts], 95% confidence interval [CI]: +9 ppts, +31 ppts) and literacy (AMD: +6 ppts, 95% CI: +0.2, +11), and negatively associated with >4 hours in income-generating activities per day (APD: -19 ppts, 95% CI: -30 ppts, -9 ppts). In girls, HEP was positively associated with no child marriage (APD: +16 ppts, 95% CI: +4 ppts, +27 ppts), no adolescent pregnancy (APD: +17 ppts, 95% CI: +6 ppts, +28 ppts), education enrolment (APD: +27 ppts, 95% CI: +15 ppts, +39 ppts), literacy (AMD: +5 ppts, 95% CI: +0.2, +11), and numeracy (AMD: +8 ppts, 95% CI: +3; +13). DISCUSSION: Policies promoting HEP are likely to have supported improvements in multiple areas of adolescents' lives in Ethiopia.

Virome of Ixodes ricinus, Dermacentor reticulatus, and Haemaphysalis concinna Ticks from Croatia.

Tick-borne diseases are a serious threat to both public and veterinary health. In this study, we used high-throughput sequencing to characterize the virome of three tick species implicated in the spread of vector-borne disease throughout Croatia. Ten viruses were identified, including seven potential novel species within the viral families Flaviviridae, Nyamiviridae, Rhabdoviridae, Peribunyaviridae, Phenuiviridae, and Nairoviridae.

The Diversity and Distribution of Viruses Associated with Culex annulirostris Mosquitoes from the Kimberley Region of Western Australia.

Metagenomics revealed an impressive breadth of previously unrecognized viruses. Here, we report the virome of the Culex annulirostris Skuse mosquito, an important vector of pathogenic arboviruses in Australia. Mosquitoes were collected from three sites in the Kimberley region of Western Australia. Unbiased high-throughput sequencing (HTS) revealed the presence of 16 novel viral sequences that share less than 90% identity with known viruses. None were closely related to pathogenic arboviruses. Viruses were distributed unevenly across sites, indicating a heterogeneous Cx. annulirostris virome. Polymerase chain reaction assays confirmed HTS data and identified marked variation between the virus prevalence identified at each site.

Discovery of Jogalong virus, a novel hepacivirus identified in a Culex annulirostris (Skuse) mosquito from the Kimberley region of Western Australia.

The discovery of hepaciviruses in non-human hosts has accelerated following the advancement of high-throughput sequencing technology. Hepaciviruses have now been described in reptiles, fish, birds, and an extensive array of mammals. Using metagenomic sequencing on pooled samples of field-collected Culex annulirostris mosquitoes, we discovered a divergent hepacivirus-like sequence, named Jogalong virus, from the Kimberley region in northern Western Australia. Using PCR, we screened the same 300 individual mosquitoes and found just a single positive sample (1/300, 0.33%). Phylogenetic analysis of the hepacivirus NS5B protein places Jogalong virus within the genus Hepacivirus but on a distinct and deeply rooted monophyletic branch shared with duck hepacivirus, suggesting a notably different evolutionary history. Vertebrate barcoding PCR targeting two mitochondrial genes, cytochrome c oxidase subunit I and cytochrome b, indicated that the Jogalong virus-positive mosquito had recently fed on the tawny frogmouth (Podargus strigoides), although it is currently unknown whether this bird species contributes to the natural ecology of this virus.

The Long-Term Effects of Group-Based Psychological Interventions for Children With Tourette Syndrome: A Randomized Controlled Trial.

This randomized controlled trial examined the long-term effects of group-based psychological interventions on measures of tic severity, self-reported quality of life (QOL), and school attendance. Children (n = 28) with Tourette syndrome (TS) were assessed 12 months after completing a course of either group-based Habit Reversal Training (HRT) or Education. Both groups demonstrated long-term improvement in tic severity and QOL, which included significant continued improvement during the follow-up (FU) period. Both groups also showed significant posttreatment improvement in school attendance. Further research is required to explore potential therapeutic mechanisms, independent or mutual, which may underlie long-term symptom improvements.

Mixed methods evaluation of the Getting it Right First Time programme - improvements to NHS orthopaedic care in England: study protocol.

BACKGROUND: Orthopaedic procedures, such as total hip replacement and total knee replacement, are among the commonest surgical procedures in England. The Getting it Right First Time project (GIRFT) aims to deliver improvements in quality and reductions in the cost of NHS orthopaedic care across the country. We will examine whether the planned changes have delivered improvements in the quality of care and patient outcomes. We will also study the processes involved in developing and implementing changes to care, and professional and organisational factors influencing these processes. In doing so, we will identify lessons to guide future improvement work in other services. METHODS/DESIGN: We will evaluate the implementation of the GIRFT programme, and its impact on outcomes and cost, using a mixed methods design. Qualitative methods will be used to understand the programme theory underlying the approach and study the effect of the intervention on practice, using a case study approach. This will include an analysis of the central GIRFT programme and local provider responses. Data will be collected via semi-structured interviews, non-participant observation, and documentary analysis. Quantitative methods will be used to examine 'what works and at what cost?' We will also conduct focus groups with patients and members of the public to explore their perceptions of the GIRFT programme. The research will draw on theories of adoption, diffusion, and sustainability of innovation; its characteristics; and contextual factors at provider-level that influence implementation. DISCUSSION: We will identify generalisable lessons to inform the organisation and delivery of future improvement programmes, to optimise their implementation and impact, both within the UK and internationally. Potential challenges involved in conducting the evaluation include the phased implementation of the intervention in different provider organisations; the inclusion of both retrospective and prospective components; and the effects of ongoing organisational turbulence in the English NHS. However, these issues reflect the realities of service change and its evaluation.

Habit reversal training and educational group treatments for children with tourette syndrome: A preliminary randomised controlled trial.

Quality of life of children with Tourette Syndrome (TS) is impacted greatly by its symptoms and their social consequences. Habit Reversal Training (HRT) is effective but has not, until now, been empirically evaluated in groups. This randomised controlled trial evaluated feasibility and preliminary efficacy of eight HRT group sessions compared to eight Education group sessions. Thirty-three children aged 9-13 years with TS or Chronic Tic Disorder took part. Outcomes evaluated were tic severity and quality of life (QoL). Tic severity improvements were found in both groups. Motor tic severity (Yale Global Tic Severity Scale) showed greatest improvements in the HRT group. Both groups showed a strong tendency toward improvements in patient reported QoL. In conclusion, group-based treatments for TS are feasible and exposure to other children with tics did not increase tic expression. HRT led to greater reductions in tic severity than Education. Implications, such as cost-effectiveness of treatment delivery, are discussed.

Assessment of the need for palliative care for children in South Africa.

UNICEF and the International Children's Palliative Care Network undertook a joint analysis in three sub-Saharan countries-Zimbabwe, South Africa, and Kenya-to estimate the palliative care need among their children and to explore these countries' capacities to deliver children's palliative care (CPC). This report concerns the findings from South Africa. The study adopted a cross-sectional mixed-methods approach using both quantitative and qualitative data obtained from primary and secondary sources. CPC need was estimated using prevalence and mortality statistics. The response to the need and existing gaps were analysed using data obtained from a literature review, interviews with key persons, and survey data from service providers.The findings show very limited CPC service coverage for children in the public sector. In addition, services are mainly localised, with minimal reach. Less than 5% of the children needing care in South Africa are receiving it, with those receiving it being closer to the end of life. Barriers to the delivery of CPC include fear of opioid use, lack of education on CPC, lack of integration into the primary care system, lack of policies on CPC, and lack of community and health professional awareness of CPC needs and services. Estimating the need for CPC is a critical step in meeting the needs of children with life-threatening conditions and provides a sound platform to advocate for closure of the unacceptably wide gaps in coverage.

Social behavior and characteristics of autism spectrum disorder in Angelman, Cornelia de Lange, and Cri du Chat syndromes.

We evaluated autism spectrum disorder (ASD) characteristics and social behavior in Angelman (AS; n  =  19; mean age  = 10.35 years), Cornelia de Lange (CdLS; n  =  15; mean age  = 12.40 years), and Cri du Chat (CdCS, also known as 5 p-syndrome; n  =  19; mean age  =  8.80 years) syndromes. The proportion of individuals meeting the ASD cutoff on the Social Communication Questionnaire was significantly higher in the AS and CdLS groups than in the CdCS group (p < .01). The groups demonstrated divergent social behavior profiles during social conditions in which adult availability, adult familiarity, and social demand were manipulated. Social enjoyment was significantly heightened in AS, whereas social approaches were heightened in individuals with CdCS. Social motivation, social communication, and enjoyment were significantly lower in CdLS. The findings highlight the importance of detailed observation when evaluating ASD and social behavior in genetic syndromes.

Who is the vulnerable child? Using survey data to identify children at risk in the era of HIV and AIDS.

Over the past decade, there has been increasing global attention to mitigating the impacts of the HIV/AIDS epidemic on children's lives. Within this context, developing and tracking global child vulnerability indicators in relation to HIV and AIDS has been critical in terms of assessing need and monitoring progress. Although orphanhood and adult household illness (co-residence with a chronically ill or HIV-positive adult) are frequently used as markers, or definitions, of vulnerability for children affected by HIV and AIDS, evidence supporting their effectiveness has been equivocal. Data from 60 nationally representative household surveys (36 countries) were analyzed using bivariate and multivariate methods to establish if these markers consistently identified children with worse outcomes and also to identify other factors associated with adverse outcomes for children. Outcome measures utilized were wasting among children aged 0-4 years, school attendance among children aged 10-14 years, and early sexual debut among adolescent boys and girls aged 15-17 years. Results indicate that orphanhood and co-residence with a chronically ill or HIV-positive adult are not universally robust measures of child vulnerability across national and epidemic contexts. For wasting, early sexual debut, and to a lesser extent, school attendance, in the majority of surveys analyzed, there were few significant differences between orphans and non-orphans or children living with chronically ill or HIV-positive adults and children not living with chronically ill or HIV-positive adults. Of other factors analyzed, children living in households where the household head or eldest female had a primary education or higher were significantly more likely to be attending school, better household health and sanitation was significantly associated with less wasting, and greater household wealth was significantly associated both with less wasting and better school attendance. Of all marker of child vulnerability analyzed, only household wealth consistently showed power to differentiate across age-disaggregated outcomes. Overall, the findings indicate the need for a multivalent approach to defining child vulnerability, one which incorporates household wealth as a key predictor of child vulnerability.

Enhancing care, improving quality: the six roles of the general practice nurse.

OBJECTIVE: To describe the evolving roles of practice nurses in Australia and the impact of nurses on general practice function. DESIGN, SETTING AND PARTICIPANTS: Multimethod research in two substudies: (a) a rapid appraisal based on observation, photographs of workspaces, and interviews with nurses, doctors and managers in 25 practices in Victoria and New South Wales, conducted between September 2005 and March 2006; and (b) naturalistic longitudinal case studies of introduced change in seven practices in Victoria, NSW, South Australia, Queensland and Western Australia, conducted between January 2007 and March 2008. RESULTS: We identified six roles of nurses in general practice: patient carer, organiser, quality controller, problem solver, educator and agent of connectivity. Although the first three roles are appreciated as nursing strengths by both nurses and doctors, doctors tended not to recognise nurses' educator and problem solver roles within the practice. Only 21% of the clinical activities undertaken by nurses were directly funded through Medicare. The role of the nurse as an agent of connectivity, uniting the different workers within the practice organisation, is particularly notable in small and medium-sized practices, and may be a key determinant of organisational resilience. CONCLUSION: Nursing roles may be enhanced through progressive broadening of the scope of the patient care role, fostering the nurse educator role, and addressing barriers to role enhancement, such as organisational inexperience with interprofessional work and lack of a career structure. In adjusting the funding structure for nurses, care should be taken not to create perverse incentives to limit nurses' clinical capacity or undermine the flexibility that gives practice nursing much of its value for nurses and practices.

Contributions from the lifeworld: quality, caring and the general practice nurse.

INTRODUCTION: Enhancing quality and safety in primary health systems is of central importance to funders, practitioners, policy makers and consumers. In this paper we explore the roles of general practice nurses in relation to quality and safety. METHOD: Cross-sectional multimethod study of 25 Australian general practices. Using rapid appraisal we collected data for each practice from interviews with practice nurses, general practitioners and practice managers; photographs of nurse-identified 'key workspaces'; structured observation of nurses for two one-hour sessions; and floor plans. RESULTS: Quality was articulated in two domains, reflecting both external and intrinsic determinants. External determinants included a large number of essentially structural, procedural or regulatory processes, the most marked of these being practice accreditation and occupational health and safety; these corresponded to the Habermasian idea of system. Intrinsic determinants related mostly to nurse perception of their own quality behaviour, and consisted of ways and means to improve or optimise patient care; these correspond to Habermas' notion of the lifeworld. DISCUSSION: Nurses describe a productive tension between the regulatory roles that they play in general practices, and patient-focused care, contrary to Habermas' suggestion that system subsumes lifeworld. Current funding systems often fail to recognise the importance of the particular elements of nurse contributions to quality and safety in primary care.

Time to talk, time to see: changing microeconomies of professional practice among nurses and doctors in Australian general practice.

In Australia, more nurses are entering general practice, and nurses' work is being funded in increasingly complex ways through Medicare. Little research has explored the ways doctors and nurses realign their priorities and activities when working together in general practice. We undertook rapid, intensive multimethod studies of 25 general practices to explore the ways in which the labour of nurses and doctors was structured, and the implicit decisions made by both professions about the values placed on different ways of working and on their time. Data collected included photographs, floor-plans, interviews with 37 nurses, 24 doctors and 22 practice managers, and 50 hours of structured observation. Nursing time was constructed by both nurses and doctors as being fluid and non-contingent; they were regarded as being 'available' to patients in a way that doctors were not. Compared to medical time, nursing time could be disposed more flexibly, underpinning a valorized attribute of nursing: deep clinical and personal contact with patients. The location of practice nurses' desks in areas of traffic, such as administrative stations, or in the treatment room, underpinned this valuable unstructured contact with patients. Changes to the practice nurse role through direct fee-for-service items for nurses may lead to greater congruence between the microeconomies of nursing and medicine in general practice. In a time of pressure upon a primary care workforce, this is likely to lead to more independent clinical work by nurses, but may also lead to a decrease in flexible contact with patients.

What supports effective research links between Divisions of General Practice and universities?

OBJECTIVE: To find out what supports effective links between Divisions of General Practice and universities. DESIGN: Qualitative study based on semi-structured interviews during October 2004, from which a framework for effective linking was constructed and its validity assessed by discussion with researchers and Division staff and members at four interactive workshops held between 9 November 2004 and 5 November 2005 . PARTICIPANTS: 21 participants from Divisions of General Practice and universities in Australia. RESULTS: Qualities conceptualised as "opportunity" and "fair relationships" were critical factors in establishing successful links between the two sectors. The relationship between these two factors describes the types of interactions that currently occur. CONCLUSIONS: To develop effective links requires an environment that promotes adequate opportunities, and in which mutual trust can grow. This will require commitment and system change from all parties.

Proactive asthma care in childhood: general practice based randomised controlled trial.

OBJECTIVES: To assess the feasibility and effectiveness of a general practice based, proactive system of asthma care in children. DESIGN: Randomised controlled trial with cluster sampling by general practice. SETTING: General practices in the northern region of the Australian Capital Territory. PARTICIPANTS: 174 children with moderate to severe asthma who attended 24 general practitioners. INTERVENTION: System of structured asthma care (the 3+ visit plan), with participating families reminded to attend the general practitioner. MAIN OUTCOME MEASURES: Process measures: rates for asthma consultations with general practitioner, written asthma plans, completion of the 3+ visit plan; clinical measures: rates for emergency department visits for asthma, days absent from school, symptom-free days, symptoms over the past year, activity limitation over the past year, and asthma drug use over the past year; spirometric lung function measures before and after cold air challenge. RESULTS: Intervention group children had significantly more asthma related consultations (odds ratio for three or more asthma related consultations 3.8 (95% confidence interval 1.9 to 7.6; P = 0.0001), written asthma plans (2.2 (1.2 to 4.1); P = 0.01), and completed 3+ visit plans (24.2 (5.7 to 103.2); P = 0.0001) than control children and a mean reduction in measurements of forced expiratory volume in one second after cold air challenge of 2.6% (1.7 to 3.5); P = 0.0001) less than control children. The number needed to treat (benefit) for one additional written asthma action plan was 5 (3 to 41) children. Intervention group children had lower emergency department attendance rates for asthma (odds ratio 0.4 (0.2 to 1.04); P = 0.06) and less speech limiting wheeze (0.2 (0.1 to 0.4); P = 0.0001) than control children and were more likely to use a spacer (2.8 (1.6 to 4.7); P = 0.0001). No differences occurred in number of days absent from school or symptom-free day scores. CONCLUSIONS: Proactive care with active recall for children with moderate to severe asthma is feasible in general practice and seems to be beneficial.
