The threshold criteria for the 75g oral glucose tolerance test in pregnancy and short-term adverse pregnancy outcomes
The significant threshold values for the 75g oGTT during pregnancy have yet to be conclusively determined. The study aims to identify the risk significance of a borderline oGTT result. Women undergoing a 75g OGTT during the third trimester of pregnancy were classified into two groups - borderline tolerance (2-h post-load glucose 8.0-8.5 mmol/l: n=75), and GDM (2:8.6 mmol/l: n=236). Outcome indicators of these two groups of women were compared to the parameters of the women with a presumed normal carbohydrate metabolism (n = 12185). GDM women showed themselves to be at a significantly increased risk of developing hypertensive disorders during pregnancy and to require obstetric intervention in the form of induction of labour and caesarean section. Their infants were more likely to be macrosomic or preterm and having a low Apgar score at birth. Shoulder dystocia was similarly more likely in infants born to GDM mothers. Women with borderline glucose tolerance did not in any way show any statistically significant increased predisposition to these complications. It would appear the significant threshold for the 75g oGTT during pregnancy should be of the order proposed by the American Diabetes Association criteria where the 2-hour post-load glucose value is 2: 8.6 mmol/l.peer-reviewe
Does religiosity influence venture capital investment decisions?
Theories on contextual behavior (e.g., social norm, self-identity, and legitimacy theories) suggest that the religiosity of the geographical area in which an organization operates influences its behavior. Using a sample of 91,020 VC investments in the U.S., we study whether religiosity influences VC investment decisions. Based on prior literature that finds a positive relation between religiosity and risk aversion, we posit that VCs located in more religious counties make less risky investments. We find that VCs located in more religious areas are more likely to be involved in staging and syndication and have a greater propensity to invest in later and expansion stages of portfolio companies. Taken together, our results suggest that VCs located in religious counties tend to be more risk averse
Learning to be green: Accounting comparability and environmental violations
This is the final version. Available on open access from Elsevier via the DOI in this recordData availability:
Data will be made available on request.Over recent years there has been an increasing awareness of the costs to the environment of corporate actions. We posit that accounting comparability between a firm and its peers, facilitates firm learning of the impact peer firm activities have on the environment. This learning allows the firm to reduce its own environmental violations. In line with this conjecture, our findings show that accounting comparability is negatively associated with environmental violations. Further, the reduction in firm environmental violations is larger in the presence of comparable peer firms disclosing low toxic releases, suggesting that firms are better able to learn from peer firms with low environmental impact. Our results provide novel evidence that accounting comparability facilitates green learning and therefore benefits society at large by reducing environmental harm
Governance of Arctic Marine Shipping
The governance of shipping activities in the Arctic might be described as a “complicated mosaic.” The 1982 United Nations Convention on the Law of the Sea (UNCLOS), often referred to as the constitution of the oceans, sets out the overall legal framework for the regulation of shipping. The Convention sets out coastal state legislative and enforcement powers over foreign ships according to the maritime zones of jurisdiction laid out in the Convention. A fragmented array of international agreements attempts to address specific challenges raised by shipping such as marine pollution prevention standards, ship safety, seafarer rights and qualifications, and liability and compensation for spills (Appendix A). In addition, the threats raised to/by ships operating in ice-covered waters have led northern countries that border these waters, such as Canada and Russia, to adopt national legislation specifically for Arctic shipping (Appendix B)

Resilience intervention for families of autistic children : reviewing the literature
: Given the rising diagnostic rates of autism, it is imperative to investigate
the well-being of families with autistic children. Families of autistic children report
more mental health difficulties than families of typically developing children.
Resilience is identified as a key protective factor for mental health difficulties in
many populations, and research suggests that this construct is effective for coping
with mental health difficulties in families of autistic children. However, reviews
on resilience interventions for families of autistic children are lacking.
Accordingly, this paper aims to report (a) common mental health difficulties that
families of autistic children experience, (b) how resilience may reduce mental
health difficulties, (c) interventions to enhance resilience in families of autistic
children, and (d) discuss implications for practice and future research. Our review
identified that mental distress resulting from feelings of uncertainty and
helplessness following a diagnosis, in addition to caregiving stressors, is especially
common among families of autistic children. Enhancing resilience is suggested to
reduce those difficulties by tapping into strengths related to various positive
psychological resources such as internal locus of control, positive cognitive
appraisal, acceptance and self-efficacy. Interventions such as Dance Movement
Psychotherapy and spirituality-based approaches, are deemed especially helpful to
families of autistic children. However, research in this area is still underdeveloped, and there is a pressing need to build a more rigorous evidence base.
Findings reviewed in the current work can aid families of autistic children,
healthcare practitioners, and researchers to support the mental wellbeing of
families of autistic children, which in turn would support the wellbeing of autistic
children
An Interlaboratory Study on the Stability of All-Printable Hole Transport Material–Free Perovskite Solar Cells
Comparisons between different laboratories on long-term stability analyses of perovskite solar cells (PSCs) is still lacking in the literature. This work presents the results of an interlaboratory study conducted between five laboratories from four countries. Carbon-based PSCs are prepared by screen printing, encapsulated, and sent to different laboratories across Europe to assess their stability by the application of three ISOS aging protocols: (a) in the dark (ISOS-D), (b) under simulated sunlight (ISOS-L), and (c) outdoors (ISOS-O). Over 1000 h stability is reported for devices in the dark, both at room temperature and at 65 degrees C. Under continuous illumination at open circuit, cells survive only for few hours, although they recover after being stored in the dark. Better stability is observed for cells biased at maximum power point under illumination. Finally, devices operate in outdoors for 30 days, with minor degradation, in two different locations (Barcelona, Spain and Paola, Malta). The findings demonstrate that open-circuit conditions are too severe for stability assessment and that the diurnal variation of the photovoltaic parameters reveals performance to be strongly limited by the fill factor, in the central hours of the day, due to the high series resistance of the carbon electrode
Coordination by Cdc42 of actin, contractility, and adhesion for melanoblast movement in mouse skin
YesThe individual molecular pathways downstream of Cdc42, Rac, and Rho GTPases are well documented, but we know surprisingly little about how these pathways are coordinated when cells move in a complex environment in vivo. In the developing embryo, melanoblasts originating from the neural crest must traverse the dermis to reach the epidermis of the skin and hair follicles. We previously established that Rac1 signals via Scar/WAVE and Arp2/3 to effect pseudopod extension and migration of melanoblasts in skin. Here we show that RhoA is redundant in the melanocyte lineage but that Cdc42 coordinates multiple motility systems independent of Rac1. Similar to Rac1 knockouts, Cdc42 null mice displayed a severe loss of pigmentation, and melanoblasts showed cell-cycle progression, migration, and cytokinesis defects. However, unlike Rac1 knockouts, Cdc42 null melanoblasts were elongated and displayed large, bulky pseudopods with dynamic actin bursts. Despite assuming an elongated shape usually associated with fast mesenchymal motility, Cdc42 knockout melanoblasts migrated slowly and inefficiently in the epidermis, with nearly static pseudopods. Although much of the basic actin machinery was intact, Cdc42 null cells lacked the ability to polarize their Golgi and coordinate motility systems for efficient movement. Loss of Cdc42 de-coupled three main systems: actin assembly via the formin FMNL2 and Arp2/3, active myosin-II localization, and integrin-based adhesion dynamics.Cancer Research UK (to L.M.M.

Financing intersectoral action for health: a systematic review of co-financing models.
BACKGROUND: Addressing the social and other non-biological determinants of health largely depends on policies and programmes implemented outside the health sector. While there is growing evidence on the effectiveness of interventions that tackle these upstream determinants, the health sector does not typically prioritise them. From a health perspective, they may not be cost-effective because their non-health outcomes tend to be ignored. Non-health sectors may, in turn, undervalue interventions with important co-benefits for population health, given their focus on their own sectoral objectives. The societal value of win-win interventions with impacts on multiple development goals may, therefore, be under-valued and under-resourced, as a result of siloed resource allocation mechanisms. Pooling budgets across sectors could ensure the total multi-sectoral value of these interventions is captured, and sectors' shared goals are achieved more efficiently. Under such a co-financing approach, the cost of interventions with multi-sectoral outcomes would be shared by benefiting sectors, stimulating mutually beneficial cross-sectoral investments. Leveraging funding in other sectors could off-set flat-lining global development assistance for health and optimise public spending. Although there have been experiments with such cross-sectoral co-financing in several settings, there has been limited analysis to examine these models, their performance and their institutional feasibility. AIM: This study aimed to identify and characterise cross-sectoral co-financing models, their operational modalities, effectiveness, and institutional enablers and barriers. METHODS: We conducted a systematic review of peer-reviewed and grey literature, following PRISMA guidelines. Studies were included if data was provided on interventions funded across two or more sectors, or multiple budgets. Extracted data were categorised and qualitatively coded. RESULTS: Of 2751 publications screened, 81 cases of co-financing were identified. Most were from high-income countries (93%), but six innovative models were found in Uganda, Brazil, El Salvador, Mozambique, Zambia, and Kenya that also included non-public and international payers. The highest number of cases involved the health (93%), social care (64%) and education (22%) sectors. Co-financing models were most often implemented with the intention of integrating services across sectors for defined target populations, although models were also found aimed at health promotion activities outside the health sector and cross-sectoral financial rewards. Interventions were either implemented and governed by a single sector or delivered in an integrated manner with cross-sectoral accountability. Resource constraints and political relevance emerged as key enablers of co-financing, while lack of clarity around the roles of different sectoral players and the objectives of the pooling were found to be barriers to success. Although rigorous impact or economic evaluations were scarce, positive process measures were frequently reported with some evidence suggesting co-financing contributed to improved outcomes. CONCLUSION: Co-financing remains in an exploratory phase, with diverse models having been implemented across sectors and settings. By incentivising intersectoral action on structural inequities and barriers to health interventions, such a novel financing mechanism could contribute to more effective engagement of non-health sectors; to efficiency gains in the financing of universal health coverage; and to simultaneously achieving health and other well-being related sustainable development goals
