Mental health and psychosocial interventions integrating sexual and reproductive rights and health, and HIV care and prevention for adolescents and young people (10-24 years) in sub-Saharan Africa: a systematic scoping review.
BACKGROUND
Interventions targeting combined sexual and reproductive health, Human Immunodeficiency Virus (HIV) management and mental health care in sub-Saharan Africa (SSA) are few. There is a need to address common determinants of poor mental, psychosocial and sexual and reproductive health and rights (SRHR) through multimodal and multipronged interventions for adolescents. The main objective of this study was to identify whether and how interventions targeting adolescent SRHR and HIV with a focus on pregnant and parenting adolescents in SSA include mental health components and how these components and their outcomes have been reported in the literature.
METHODS
We carried out a two process scoping review approach between 01.04.2021 and 23.08.2022. In the first stage, we searched the PubMed database to identify studies focusing on adolescents and young people aged 10 to 24 from 2001 to 2021. We identified studies focusing on HIV and SRHR that had mental health and psychosocial aspects to the interventions. Our search yielded 7025 studies. Of these 38 were eligible based on our screening criteria that covered interventions, and on further scrutiny, using PracticeWise, an established coding system, we identified select problems and practices to provide a more granular assessment of how interventions developed for this context mapped on to specific problems. At this second stage process, we selected 27 studies for inclusion as actual interventional designs for further systematic scoping of their findings and we used the Joanna Briggs Quality Appraisal checklist to rate these studies. This review was registered within the International Prospective Register of Systematic Reviews (PROSPERO), number CRD42021234627.
FINDINGS
Our first set of findings is that when coding problems and solutions, mental health concerns were the least common category of problems targeted in these SRHR/HIV interventions; nevertheless, psychoeducation and cognitive behavioral strategies such as improved communication, assertiveness training, and informational support were offered widely. Of the 27 interventional studies included in the final review, 17 RCTs, 7 open trials, and 3 mixed designs, represented nine countries of the 46 countries in SSA. Intervention types included peer, community, family, digital, and mixed modality interventions. Eight interventions focused on caregivers and youth. Social or community ecology associated problems (being an orphan, sexual abuse, homelessness, negative cultural norms) were the most common risk factors and were more frequent than medical issues associated with HIV exposure. Our findings highlight the relevance and centrality of social issues related to adolescent mental and physical health along with the need to strengthen multimodal interventions along the lines of problems we have identified in our review.
INTERPRETATION
Combined interventions jointly addressing adolescent SRHR, HIV, and mental health have been relatively understudied, despite evidence that adverse social and community factors are rampant in this population.

Review
To assess the risk factors perceived as stressors by pregnant women in the work environment and the possible adverse consequences of such exposure for the normal development of pregnancy. Systematic review, guided by the PRISMA guidelines, and using Pubmed, Web of Science, Dialnet, SciELO, and REDIB databases. Methodological quality was assessed using the critical appraisal tools for non-randomised studies of the Joanna Briggs Institute. A total of 38 studies were included. The main risk factors found in the work environment of pregnant women were chemical, psychosocial, physical-ergonomic-mechanical factors, and other work-related factors. The main adverse consequences of exposure to these factors include low birth weight, preterm birth, miscarriage, hypertension and pre-eclampsia, as well as various obstetric complications. During pregnancy, working conditions that are considered acceptable in normal situations may not be so during this stage due to the major changes that occur during pregnancy. Many obstetric effects may have an important impact in the mother's psychological status; therefore, it is important to optimise working conditions during this stage and to reduce or eliminate possible risks.

Review
BACKGROUND
Regulated cell death is a fundamental component of numerous physiological processes; spanning from organogenesis in utero, to normal cell turnover during adulthood, as well as the elimination of infected or damaged cells throughout life. Quality control through regulation of cell death pathways is particularly important in the germline, which is responsible for the generation of offspring. Women are born with their entire supply of germ cells, housed in functional units known as follicles. Follicles contain an oocyte, as well as specialized somatic granulosa cells essential for oocyte survival. Follicle loss-via regulated cell death-occurs throughout follicle development and life, and can be accelerated following exposure to various environmental and lifestyle factors. It is thought that the elimination of damaged follicles is necessary to ensure that only the best quality oocytes are available for reproduction.
OBJECTIVE AND RATIONALE
Understanding the precise factors involved in triggering and executing follicle death is crucial to uncovering how follicle endowment is initially determined, as well as how follicle number is maintained throughout puberty, reproductive life, and ovarian ageing in women. Apoptosis is established as essential for ovarian homeostasis at all stages of development and life. However, involvement of other cell death pathways in the ovary is less established. This review aims to summarize the most recent literature on cell death regulators in the ovary, with a particular focus on non-apoptotic pathways and their functions throughout the discrete stages of ovarian development and reproductive life.
SEARCH METHODS
Comprehensive literature searches were carried out using PubMed and Google Scholar for human, animal, and cellular studies published until August 2022 using the following search terms: oogenesis, follicle formation, follicle atresia, oocyte loss, oocyte apoptosis, regulated cell death in the ovary, non-apoptotic cell death in the ovary, premature ovarian insufficiency, primordial follicles, oocyte quality control, granulosa cell death, autophagy in the ovary, autophagy in oocytes, necroptosis in the ovary, necroptosis in oocytes, pyroptosis in the ovary, pyroptosis in oocytes, parthanatos in the ovary, and parthanatos in oocytes.
OUTCOMES
Numerous regulated cell death pathways operate in mammalian cells, including apoptosis, autophagic cell death, necroptosis, and pyroptosis. However, our understanding of the distinct cell death mediators in each ovarian cell type and follicle class across the different stages of life remains the source of ongoing investigation. Here, we highlight recent evidence for the contribution of non-apoptotic pathways to ovarian development and function. In particular, we discuss the involvement of autophagy during follicle formation and the role of autophagic cell death, necroptosis, pyroptosis, and parthanatos during follicle atresia, particularly in response to physiological stressors (e.g. oxidative stress).
WIDER IMPLICATIONS
Improved knowledge of the roles of each regulated cell death pathway in the ovary is vital for understanding ovarian development, as well as maintenance of ovarian function throughout the lifespan. This information is pertinent not only to our understanding of endocrine health, reproductive health, and fertility in women but also to enable identification of novel fertility preservation targets.

The C4 grass pearl millet is one of the most drought tolerant cereals and is primarily grown in marginal areas where annual rainfall is low and intermittent. It was domesticated in sub-Saharan Africa, and several studies have found that it uses a combination of morphological and physiological traits to successfully resist drought. This review explores the short term and long-term responses of pearl millet that enables it to either tolerate, avoid, escape, or recover from drought stress. The response to short term drought reveals fine tuning of osmotic adjustment, stomatal conductance, and ROS scavenging ability, along with ABA and ethylene transduction. Equally important are longer term developmental plasticity in tillering, root development, leaf adaptations and flowering time that can both help avoid the worst water stress and recover some of the yield losses asynchronous tiller production. We examine genes related to drought resistance that were identified through individual transcriptomic studies and through our combined analysis of previous studies. From the combined analysis, we found 94 genes that were differentially expressed in both vegetative and reproductive stages under drought stress. Among them is a tight cluster of genes that are directly related to biotic and abiotic stress, as well as carbon metabolism, and hormonal pathways. We suggest that knowledge of gene expression patterns in tiller buds, inflorescences and rooting tips will be important for understanding the growth responses of pearl millet and the trade-offs at play in the response of this crop to drought. Much remains to be learnt about how pearl millet's unique combination of genetic and physiological mechanisms allow it to achieve such high drought tolerance, and the answers to be found may well be useful for crops other than just pearl millet.

Review
Despite an increasing number of studies examining the impact of parental incarceration on children's well-being, there are few comprehensive reviews that collect this information, and even fewer from a developmental perspective. This study aims to clarify the effects of parental incarceration on children's well-being and development, as well as the moderating and mediating factors from a developmental perspective. A systematic review was conducted according to PRISMA guidelines, selecting 61 studies of children from early childhood to adolescence. The results show differences in the current evidence regarding the effects of parental incarceration on children depending on the developmental stage, with the most evidence in the 7-11-year-old stage. Being male appears as a risk moderator factor while the mental health of the caregiver and their relationship with the child appears as a mediating variable, especially from 7 to 18 years old. These results reveal the impact of parental incarceration based on children's age, providing a basis for developing protective and intervention measures.

Review
BACKGROUND
In March 2020, the COVID-19 outbreak was declared a pandemic by the World Health Organization (WHO), generating stark economic and social repercussions that directly or indirectly affected families' wellbeing and health status.
AIMS
This review aims at mapping the existing evidence on the impact of the COVID-19 pandemic on maternal mental health, early childhood development, and parental practices, worldwide, to identify evidence gaps and better inform future delivery of care and health policy measures.
METHODS
Following the protocol defined by PRISMA-ScR, this scoping review has searched for relevant studies published between January 2020 and June 2021, selecting evidence sources based on pre-established criteria. From a total of 2,308 articles, data were extracted from 537 publications from 35 countries on all three health domains.
RESULTS
The combined stressors brought forth by the pandemic have exerted a heavy burden on the mental health of mothers and the development of young children, partly mediated by its impact on parental practices.
CONCLUSIONS
Despite remaining gaps, we have identified sufficient evidence pointing to an urgent need for more concerted global research efforts and rapid policy responses to timely address severe and pervasive negative impacts to the mental health of mothers and children at a key developmental stage.

Review
OBJECTIVES
Individuals with fetal alcohol spectrum disorder (FASD) are over-represented within the justice system and have significant employment challenges. The primary aim of this scoping review was to ascertain available employment resources for FASD individuals particularly those involved in the justice system. Secondary aims were to determine available evidence-based interventions for the justice workforce and employment providers.
METHODS
: That the resource was (a) published between 1990 and 2021, (b) in English, (c) available electronically in full text, (d) focused on strategies for improving employment outcomes of individuals with FASD and (f) developed for those aged over 15. Electronic searches of the following databases were conducted: EMBASE, MEDLINE, PsycINFO, Scopus, Web of Science and Google Scholar. Grey literature was collected via the databases ProQuest Dissertations & Theses Global, OpenGrey, GreyNet International and Grey Matters. Using Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews reporting guidelines, a five-stage methodological framework was employed. A quality appraisal of identified resources was conducted. Data were summarised qualitatively using a content analysis method that allowed for analysis of specific terms/themes/concepts/resource elements that resources covered, as well as a quantitative analysis of their frequency.
RESULTS
An initial search identified 850 articles, 512 of which were obtained through online database searches, 321 through Google Scholar searches and 17 through google searches. Sixteen resources were identified as meeting inclusion criteria, including four peer-reviewed papers and 12 grey literature resources. Six of the resources extracted were deemed 'good' or 'strong' quality, with the remainder-all grey literature resources-being 'adequate' or 'limited'. None of the resources identified were empirically evaluated or could be implemented synergistically. Content analysis revealed common themes addressing FASD-related employment challenges and required supports.
CONCLUSIONS
This review highlights the need for developing evidence-based employment-related resources for justice-involved people with FASD. Most of the 16 identified resources had a psychoeducational and advocacy component and described typical employment challenges with specific supports and accommodations to maximise workforce participation. However, none had been empirically evaluated, underscoring the importance of future research in this area to better inform more responsive and evidence-based employment-related programmes.

To explore the association between vitamin A (vit A) status and risk of asthma. PubMed, Web of Science, Embase and the Cochrane Library were electronically searched to identify related studies that reported the association between vit A status and asthma. All databases were searched from inception to November 2022. Two reviewers independently screened literature, extracted data, and assessed risk bias of included studies. Meta-analysis was performed on R software Version 4.1.2 and STATA Version 12.0. A total of 19 observational studies were included. A pooled analysis showed that the serum vit A concentrations in patients with asthma was lower than that in healthy controls (standard mean difference (SMD)= -2.479, 95% confidence interval (CI): -3.719, -.239, 95% prediction interval (PI): -7.510, 2.552), and relatively higher vit A intake in pregnancy was associated with an increased risk of asthma at age 7 years (risk ratio (RR)= 1.181, 95% CI: 1.048, 1.331). No significant correlation was observed between serum vit A levels or vit A intake and the risk of asthma. Our meta-analysis confirms that serum vit A levels are lower in patients with asthma than in healthy controls. Relatively higher vit A intake during pregnancy is associated with an increased risk of asthma at age 7 years. There is no significant correlation between vit A intake and asthma risk in children, nor between serum vit A levels and asthma risk. The effect of vit A may depend on age or developmental stage, diet and genetics. Therefore, further studies are needed to explore the association of vit A and asthma. https://www.crd.york.ac.uk/prospero/CRD42022358930, identifier CRD42022358930.

Although neural plasticity is now widely studied, there was a time when the idea of adult plasticity was antithetical to the mainstream. The essential stumbling block arose from the seminal experiments of Hubel and Wiesel who presented convincing evidence that there existed a critical period for plasticity during development after which the brain lost its ability to change in accordance to shifts in sensory input. Despite the zeitgeist that mature brain is relatively immutable to change, there were a number of examples of adult neural plasticity emerging in the scientific literature. Interestingly, some of the earliest of these studies involved visual plasticity in the adult cat. Even earlier, there were reports of what appeared to be functional reorganization in adult rat somatosensory thalamus after dorsal column lesions, a finding that was confirmed and extended with additional experimentation. To demonstrate that these findings reflected more than a response to central injury, and to gain greater control of the extent of the sensory loss, peripheral nerve injuries were used that eliminated ascending sensory information while leaving central pathways intact. Merzenich, Kaas, and colleagues used peripheral nerve transections to reveal unambiguous reorganization in primate somatosensory cortex. Moreover, these same researchers showed that this plasticity proceeded in no less than two stages, one immediate, and one more protracted. These findings were confirmed and extended to more expansive cortical deprivations, and further extended to the thalamus and brainstem. There then began a series of experiments to reveal the physiological, morphological and neurochemical mechanisms that permitted this plasticity. Ultimately, Mowery and colleagues conducted a series of experiments that carefully tracked the levels of expression of several subunits of glutamate (AMPA and NMDA) and GABA (GABAA and GABAB) receptor complexes in primate somatosensory cortex at several time points after peripheral nerve injury. These receptor subunit mapping experiments revealed that membrane expression levels came to reflect those seen in early phases of critical period development. This suggested that under conditions of prolonged sensory deprivation the adult cells were returning to critical period like plastic states, i.e., developmental recapitulation. Here we outline the heuristics that drive this phenomenon.

BACKGROUND
Trajectories of youth antisocial behavior (ASB) are characterized by continuity and change. Although numerous longitudinal studies have examined ASB, findings from person-centered and variable-centered research have not yet been integrated. The present paper integrates findings across statistical methods for a more comprehensive understanding of the development of ASB. Neighborhood disadvantage is considered as a core moderator.
METHODS
The study protocol was registered in the PROSPERO database of systematic reviews (registration number CRD42021255820). The PsycINFO and PubMed databases were examined (September 2022) to identify longitudinal studies of youth aggression and/or rule-breaking. Results from person-centered and variable-centered studies were integrated via narrative synthesis, and a systematic quality assessment was conducted.
RESULTS
Of 8227 studies identified, 136 met inclusion criteria. Our review indicated that rule-breaking trajectories were largely distinguished by differences in rate of change (i.e., slope), whereas aggression trajectories differed more by baseline level (i.e., intercept), particularly in childhood. For adolescents in disadvantaged neighborhoods, however, aggression trajectories differed by both intercept and slope.
CONCLUSIONS
The respective importance of the intercept and slope differed across dimensions of ASB, developmental stage, and neighborhood residence. Neighborhood disadvantage was associated with trajectories of aggression, consistent with developmental theories emphasizing the role of person-environment interactions.
