Prevalence of child maltreatment in India and its association with gender, urbanisation and policy: a rapid review and meta-analysis protocol.

INTRODUCTION: India is home to 20% of the world's children and yet, little is known on the magnitude and trends of child maltreatment nationwide. The aims of this review are to provide a prevalence of child maltreatment in India with considerations for any effects of gender; urbanisation (eg, urban vs rural) and legislation (Protection of Children from Sexual Offences (POCSO) Act 2012). METHODS AND ANALYSIS: A rapid review will be undertaken of all quantitative peer-reviewed studies on child maltreatment in India between 2005 and 2020. Four electronic databases will be systematically searched: PubMed, EMBASE, Cochrane and PsychInfo. The primary outcomes will include all aspects of child maltreatment: physical abuse, sexual abuse, emotional abuse, emotional neglect and physical neglect. Study participants will be between 0 and 18 years and will have reported maltreatment experiences using validated, reliable tools such as the Adverse Childhood Experiences Questionnaire as well as child self-reports and clinician reports. Study selection will follow the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, and the methodological appraisal of the studies will be assessed by the Newcastle-Ottawa Quality assessment scale. A narrative synthesis will be conducted for all included studies. Also, if sufficient data are available, a meta-analysis will be conducted. Effect sizes will be determined from random-effects models stratified by gender, urbanisation and the pre-2012 and post-2012 POCSO Act cut-off. I2 statistics will be used to assess heterogeneity and identify their potential sources and τ2 statistics will indicate any between-study variance. ETHICS AND DISSEMINATION: As this is a rapid review, minimal ethical risks are expected. The protocol and level 1 self-audit checklist were submitted and approved by the Usher Research Ethics Group panel in the Usher Institute (School of Medicine and Veterinary Sciences) at the University of Edinburgh (Reference B126255). Findings from this review will be disseminated widely through peer-reviewed publications and in various media, for example, conferences, congresses or symposia.

Towards 'a balanced delegation' or enhancing global health governance? Analysis of parties' participation in the Conference of the Parties to WHO Framework Convention on Tobacco Control.

INTRODUCTION: The success of the WHO Framework Convention on Tobacco Control (FCTC) depends on parties' active participation in its governance and implementation, particularly via biennial Conference of the Parties (COP) meetings. The COP's efficacy is threatened by declining attendance and reductions in travel support for low-income and middle-income countries, and there are growing concerns about transparency and representation in country delegations amid industry efforts to shape their composition. METHODS: We examined parties' participation in the COP based on official meeting records, and the relationship between attendance and strength of tobacco control based on national global tobacco control reports. RESULTS: Attendance at the COP has decreased over time, and at several meetings would have fallen below 66% (the threshold for decision-making) if it was not for high levels of participation among low-income and lower-middle-income countries. Despite their higher attendance at COP meetings, these countries represent a smaller share of meeting attendees due to the smaller size of their delegations. Additionally, there has been a decline in the proportion of delegates from ministries of health and tobacco control focal points. Nationally, COP participation is correlated with stronger tobacco control policies; attendance by low-income countries has a strong correlation with implementation of advertising bans, while attendance among high-income and lower-middle-income countries shows a moderate correlation with implementation of tobacco taxes. CONCLUSIONS: Supporting states to actively engage in the COP is crucial for ongoing FCTC implementation, strengthening national capacity for tobacco control, and protecting the legitimacy and efficacy of global health governance.

Can public health reconcile profits and pandemics? An analysis of attitudes to commercial sector engagement in health policy and research.

BACKGROUND: Public health's terms of engagement with unhealthy commodity industries (alcohol, tobacco and ultra-processed food and drinks) have become increasingly contested in policy and research. We sought to identify approaches that could attract consensus support within and across policy domains. METHODS: Using snowball sampling, we undertook an online survey of 335 health researchers, advocates and policymakers, in 40 countries, assessing responses to stated principles, claims and recommendations for engaging with unhealthy commodity industries in relation to key policy and research initiatives. RESULTS: Most respondents identified a fundamental conflict between industry interests and public health objectives for all three industries, with agreement greatest in relation to tobacco and weakest for food. This pattern was replicated across diverse questions regarding potential forms of engagement, including in rejecting voluntarism and partnership approaches to health policy. While awareness of tobacco industry tactics to influence policy and research was higher than for alcohol and food, most respondents rejected the view that the influence of the latter was less significant for public health. Proposals that health and research organisations should divest their funds attracted less support with respect to food, while restricting publication of industry-funded research in academic journals was the issue that most divided opinion. Respondents reported most difficulty in answering questions about the food industry. CONCLUSIONS: The strong consensus around restricting interactions with the tobacco industry supports increased implementation of the WHO Framework Convention on Tobacco Control's conflict of interest provisions. There is strong support for the extension of such practices to the alcohol industry, challenging current norms. More mixed responses indicate a need for greater clarity in defining the food industry, and for research analyzing links, similarities and differences across different types of unhealthy commodity producers. Partnership approaches to addressing non-communicable diseases seem incapable of attracting widespread support across public health, challenging practice in many contexts.

Chitin-glucan complex production by Komagataella pastoris: Downstream optimization and product characterization.

Purified chitin-glucan complex (CGCpure) was extracted from Komagataella pastoris biomass using a hot alkaline treatment, followed by neutralization and repeated washing with deionized water. The co-polymer thus obtained had a ß-glucan:chitin molar ratio of 75:25 and low protein and inorganic salts contents (3.0 and 0.9 wt%, respectively). CGCpure had an average molecular weight of 4.9 × 10(5)Da with a polydispersity index of 1.7, and a crystallinity index of 50%. Solid-state NMR provided structural insight at the co-polymer. X-ray diffraction suggests that CGCpure has α-chitin in its structure. CGCpure presented an endothermic decomposition peak at 315°C, assigned to the degradation of the saccharide structures. This study revealed that K. pastoris CGC has properties similar to other chitinous biopolymers and may represent an attractive alternative to crustacean chitin derived-products, being a reliable raw material for the development of new/improved pharmaceutical, cosmetic or food products.

Exosomes as drug delivery vehicles for Parkinson's disease therapy.

Exosomes are naturally occurring nanosized vesicles that have attracted considerable attention as drug delivery vehicles in the past few years. Exosomes are comprised of natural lipid bilayers with the abundance of adhesive proteins that readily interact with cellular membranes. We posit that exosomes secreted by monocytes and macrophages can provide an unprecedented opportunity to avoid entrapment in mononuclear phagocytes (as a part of the host immune system), and at the same time enhance delivery of incorporated drugs to target cells ultimately increasing drug therapeutic efficacy. In light of this, we developed a new exosomal-based delivery system for a potent antioxidant, catalase, to treat Parkinson's disease (PD). Catalase was loaded into exosomes ex vivo using different methods: the incubation at room temperature, permeabilization with saponin, freeze-thaw cycles, sonication, or extrusion. The size of the obtained catalase-loaded exosomes (exoCAT) was in the range of 100-200nm. A reformation of exosomes upon sonication and extrusion, or permeabilization with saponin resulted in high loading efficiency, sustained release, and catalase preservation against proteases degradation. Exosomes were readily taken up by neuronal cells in vitro. A considerable amount of exosomes was detected in PD mouse brain following intranasal administration. ExoCAT provided significant neuroprotective effects in in vitro and in vivo models of PD. Overall, exosome-based catalase formulations have a potential to be a versatile strategy to treat inflammatory and neurodegenerative disorders.

The 'diverse, dynamic new world of global tobacco control'? An analysis of participation in the Conference of the Parties to the WHO Framework Convention on Tobacco Control.

INTRODUCTION: The increasingly inequitable impacts of tobacco use highlight the importance of ensuring developing countries' ongoing participation in global tobacco control. The WHO Framework Convention on Tobacco Control (FCTC) has been widely regarded as reflecting the high engagement and effective influence of developing countries. METHODS: We examined participation in FCTC governance based on records from the first four meetings of the Conference of the Parties (COP), comparing representation and delegate diversity across income levels and WHO regions. RESULTS: While attendance at the COP sessions is high, there are substantial disparities in the relative representation of different income levels and regions, with lower middle and low income countries contributing only 18% and 10% of total meeting delegates, respectively. In regional terms, Europe provided the single largest share of delegates at all except the Durban (2008) meeting. Thirty-nine percent of low income countries and 27% of those from Africa were only ever represented by a single person delegation compared with 10% for high income countries and 11% for Europe. Rotation of the COP meeting location outside of Europe is associated with better representation of other regions and a stronger presence of delegates from national ministries of health and focal points for tobacco control. CONCLUSIONS: Developing countries face particular barriers to participating in the COP process, and their engagement in global tobacco control is likely to diminish in the absence of specific measures to support their effective participation.

Cross-border mobility of health professionals: contesting patients' right to health.

Cross-border labour mobility in the health sector is portrayed as both an opportunity for health professionals immigrating to developed countries, and as a challenge for patients remaining in low-income countries with restricted access to health care provision. In policy debate, this problem is articulated as the opposition between, 'the right to freedom of movement' and 'the right to health'. The underlying layers of this dilemma expose competing institutional interests for source and destination countries, international organisations, private recruitment agencies, trade unions and professional organisations. To resolve some of these tensions, a 'soft law' regulation (ethical recruitment policy) was adopted in the UK in the early 2000s. This article argues that this ethical recruitment policy produces an ambivalent effect. The qualitative content analysis refers to documents produced by international organisations, government bodies, professional organisations and trade unions in the UK and source countries. We found that ethical recruitment on the one hand proposes a practical mechanism to the realisation of the right to health in source countries, through encouraging employers' behaviour in accordance with ethical principles in international recruitment. On the other hand, this policy protects the reputation of institutional stakeholders changing rhetoric around international recruitment rather than the practice. The findings of this study contribute to a broader discussion of the international norms diffusion and the ambivalent role of 'soft law' in their implementation.
