RESUMEN

Climate change is a pressing global challenge with profound implications for human health. Forest-based climate change mitigation strategies, such as afforestation, reforestation, and sustainable forest management, offer promising solutions to mitigate climate change and simultaneously yield substantial co-benefits for human health. The objective of this scoping review was to examine research trends related to the interdisciplinary nexus between forests as carbon sinks and human health co-benefits. We developed a conceptual framework model, supporting the inclusion of exposure pathways, such as recreational opportunities or aesthetic experiences, in the co-benefit context. We used a scoping review methodology to identify the proportion of European research on forest-based mitigation strategies that acknowledge the interconnection between mitigation strategies and human impacts. We also aimed to assess whether synergies and trade-offs between forest-based carbon sink capacity and human co-benefits has been analysed and quantified. From the initial 4,062 records retrieved, 349 reports analysed European forest management principles and factors related to climate change mitigation capacity. Of those, 97 studies acknowledged human co-benefits and 13 studies quantified the impacts on exposure pathways or health co-benefits and were included for full review. Our analysis demonstrates that there is potential for synergies related to optimising carbon sink capacity together with human co-benefits, but there is currently a lack of holistic research approaches assessing these interrelationships. We suggest enhanced interdisciplinary efforts, using for example multideterminant modelling approaches, to advance evidence and understanding of the forest and health nexus in the context of climate change mitigation.

RESUMEN

There have been few reports from Africa on the use and health effects of emollient therapy for newborn infants. We aimed to describe neonatal skin care practices in Africa, and to illuminate opportunities to introduce evidence-based interventions to improve these practices. We conducted a scoping review of the quantitative and qualitative published peer-reviewed and grey literature in English on emollient use in Africa. Outcomes of interest included neonatal skin care practices, with a focus on the application of oils and other products to infant skin, including in association with bathing and massage. We screened 5257 articles and summarised findings from 23 studies-13 qualitative, nine quantitative and one mixed methods-that met our study criteria. Seven studies reported the use of emollients for perceived benefits, including thermal care, treatment for illness, promotion of growth and development, infection reduction, skin condition improvement, spirituality and lubrication to aid massage. Four studies reported the quantitative health impact of skin care product applications, including improvements in skin condition, neurodevelopment and bone growth, as well as a reduction in nosocomial infections. This review highlights opportunities for skin care intervention and future research on neonatal skin care practices in Africa.

RESUMEN

BACKGROUND: UK Children generally fail to meet physical activity (PA) recommendations. Whole school approaches (WSA) have the potential to impact large numbers of children due to their ubiquitous nature for school wide implementation, however there is limited knowledge regarding primary school PA WSA implementation in the UK. This study aimed to investigate the acceptability and feasibility of a PA WSA in the UK.  METHODS: Semi structured interviews explored research aims with participants. A qualitative description approach was adopted and data were analysed using thematic analysis to draw codes and themes from the data. RESULTS: Thirteen primary school senior leadership team (SLT) and Physical Education (PE) leads were interviewed. A PA WSA was found acceptable by all participants. Implementation, however, was questioned when other significant mechanisms were not in place. A PA WSA aided prioritisation and planning of PA provision, providing a holistic overview of all key areas of PE, school-sport and PA (PESSPA). Due to the high acceptability but dependent feasibility of a PA WSA, it is recommended that PA WSAs align with whole-school health policy and improvement plans to advance implementation. Future research, however, is needed to explore how this method is best implemented as additional interventions may also be required to promote the prioritisation of the PA agenda due to the importance of SLT backing for implementation being paramount, as results highlight. CONCLUSIONS: PA WSAs aid awareness, understanding and planning of school wide PESSPA provision, however their implementation in complex. Having SLT support and an appropriately resourced PE lead maximised the impact and utility of a PA WSA.

RESUMEN

Background: Partners from an NGO, academia, industry and government applied a tool originating in the private sector - Quantitative Decision Making (QDM) - to rigorously assess whether to invest in testing a global health intervention. The proposed NEWBORN study was designed to assess whether topical emollient therapy with sunflower seed oil in infants with very low birthweight <1500 g in Kenya would result in a significant reduction in neonatal mortality compared to standard of care. Methods: The QDM process consisted of prior elicitation, modelling of prior distributions, and simulations to assess Probability of Success (PoS) via assurance calculations. Expert opinion was elicited on the probability that emollient therapy with sunflower seed oil will have any measurable benefit on neonatal mortality based on available evidence. The distribution of effect sizes was modelled and trial data simulated using Statistical Analysis System to obtain the overall assurance which represents the PoS for the planned study. A decision-making framework was then applied to characterise the ability of the study to meet pre-selected decision-making endpoints. Results: There was a 47% chance of a positive outcome (defined as a significant relative reduction in mortality of ≥15%), a 45% chance of a negative outcome (defined as a significant relative reduction in mortality <10%), and an 8% chance of ending in the consider zone (ie, a mortality reduction of 10 to <15%) for infants <1500 g. Conclusions: QDM is a novel tool from industry which has utility for prioritisation of investments in global health, complementing existing tools [eg, Child Health and Nutrition Research Initiative]. Results from application of QDM to the NEWBORN study suggests that it has a high probability of producing clear results. Findings encourage future formation of public-private partnerships for health.

RESUMEN

According to many studies, addressing the religious and spiritual (R/S) needs of patient's increase patient satisfaction. One area of interest is how patient self-perceived level of religiosity and spirituality (R/S) influences hospital needs. In this cross-sectional study, 195 inpatients at a non-faith-based academic hospital in Toledo, OH, USA completed surveys examining self-perceived R/S levels, as well as how those R/S levels impacted preferred services, conversations, and experiences in the hospital. Patients with no religious identity (self-identified as atheist, agnostic, or no religion) were less likely to report discussions about R/S needs than religious respondents (16.7% vs. 47.3%, p = 0.039). Nevertheless, such patients were just as likely to want a R/S conversation started by their healthcare provider (75% vs. 56%, p = 0.241). Those with no R/S identity were more likely to report presumed negative assumptions by hospital staff (25% vs. 0%, p < 0.001). Our data suggests that even for a nonreligious population, it is important to consider R/S needs.

RESUMEN

Background: Serious infections and other complications from very low birth weight and prematurity are the leading causes of death for neonates worldwide. Infections partly result from the compromised skin barrier function in preterm neonates. Optimal skin care practices for neonates, especially in settings with limited access to adequate hygienic conditions, hold potential to reduce infection and avoid these preventable preterm neonatal deaths. The purpose of this protocol is to support a scoping review of neonatal skin care, emollient therapy and massage practices throughout sub-Saharan Africa. Protocol: The proposed review will follow a methodological framework consisting of the following five steps: (i) identifying the research question, (ii) identifying relevant studies, (iii) selection of eligible studies, (iv) charting the data, and (v) collating and summarizing the results. In addition, we will reflect on the implications of the findings for the feasibility and design of randomized controlled trials to examine the impact of emollient therapy on survival, growth, infection and neurodevelopment of very low birth weight infants in sub-Saharan Africa. We will search domestic and international databases for literature published in English between January 1, 2000, and July 12, 2021. Articles will be chosen based on standardized inclusion criteria. The primary criteria for inclusion will be a report on skin care practices administered to neonates in Africa. Conclusions: Documentation of common neonatal skin care practices throughout Africa has the potential to highlight opportunities for skin care intervention and future research on neonatal skin care practices in sub-Saharan Africa, and support the development of future emollient intervention trials for preterm and low birthweight neonates in low- and middle-income countries.

RESUMEN

A common missense variant in SLC39A8 is convincingly associated with schizophrenia and several additional phenotypes. Homozygous loss-of-function mutations in SLC39A8 result in undetectable serum manganese (Mn) and a Congenital Disorder of Glycosylation (CDG) due to the exquisite sensitivity of glycosyltransferases to Mn concentration. Here, we identified several Mn-related changes in human carriers of the common SLC39A8 missense allele. Analysis of structural brain MRI scans showed a dose-dependent change in the ratio of T2w to T1w signal in several regions. Comprehensive trace element analysis confirmed a specific reduction of only serum Mn, and plasma protein N-glycome profiling revealed reduced complexity and branching. N-glycome profiling from two individuals with SLC39A8-CDG showed similar but more severe alterations in branching that improved with Mn supplementation, suggesting that the common variant exists on a spectrum of hypofunction with potential for reversibility. Characterizing the functional impact of this variant will enhance our understanding of schizophrenia pathogenesis and identify novel therapeutic targets and biomarkers.

RESUMEN

This research highlights the malleability of Maternal Mortality Ratios (MMR) and the ways in which they accommodate a variety of narratives via their claims about women's access to reproductive health services. MMR plays an important role in determining fiscal and legislative priorities for women's health in Mexico and in the discursive practices that shape societal beliefs about appropriate birthing practices and birth attendants. This paper is based on ethnographic fieldwork conducted in Yucatán and Quintana Roo between 2009 and 2017 during Ministry of Health midwifery workshops and approximately fifty interviews with midwives, doctors, public health officials, and parents. It explores the mutability of MMR within the context of political struggles for midwifery in Mexico-both for and against its legality and existence. In Mexico, MMR is often used by bureaucrats and public health workers to reinforce the importance of biomedical obstetric services over midwifery. However, the same metrics are also employed by midwives in critiques of underfunded and often structurally-violent maternal health care services. While doctors attempt to use MMR to prove that birth is inherently dangerous and must take place in hospitals with access to obstetric technologies and interventions, midwives use MMR to demonstrate that birth in hospitals is risky precisely because of those technologies and their inappropriate use, and to draw international attention and funding in support of midwifery. In addition to examining the strategic use of MMR in health-related discourses, this paper interrogates techniques employed by the state to limit midwives' access to births in the name of monitoring and improving MMR. I contend that while discursive uses of MMR to advance professional and political goals are common in both midwifery and biomedicine, the asymmetric power relations of biomedicine vis-à-vis the Mexican state privilege interpretations of MMR that justify and legitimate enhanced bureaucratic surveillance of midwives.

RESUMEN

Mastery imagery has been shown to be associated with more positive cognitive and emotional responses to stress, but research is yet to investigate the influence of mastery imagery ability on imagery's effectiveness in regulating responses to acute stress, such as competition. Furthermore, little research has examined imagery's effectiveness in response to actual competition. This study examined (a) whether mastery imagery ability was associated with stress response changes to a competitive stress task, a car racing computer game, following an imagery intervention, and (b) the effects of different guided imagery content on pre-task cognitive and emotional responses. In Session 1, 78 participants (M age = 20.03 years, SD = 1.28) completed ratings of pre-task anxiety intensity and direction, confidence, and perceived control. Imagery ability was also assessed before completing the task. In Session 2, participants were randomly allocated to an imagery condition (positive mastery, negative mastery, relaxation) or control group (no imagery) before completing the task and outcome measures again. For the negative mastery group, greater positive mastery imagery ability was associated with greater perceived control and perceiving anxiety as more facilitative. Furthermore, mastery imagery ability moderated the relationship between anxiety intensity and direction. Altogether, results suggest that positive mastery imagery ability may act as a potential buffer against the effects of negative images.

RESUMEN

SHP2 is a cytoplasmic protein tyrosine phosphatase encoded by the PTPN11 gene and is involved in cell proliferation, differentiation, and survival. Recently, we reported an allosteric mechanism of inhibition that stabilizes the auto-inhibited conformation of SHP2. SHP099 (1) was identified and characterized as a moderately potent, orally bioavailable, allosteric small molecule inhibitor, which binds to a tunnel-like pocket formed by the confluence of three domains of SHP2. In this report, we describe further screening strategies that enabled the identification of a second, distinct small molecule allosteric site. SHP244 (2) was identified as a weak inhibitor of SHP2 with modest thermal stabilization of the enzyme. X-ray crystallography revealed that 2 binds and stabilizes the inactive, closed conformation of SHP2, at a distinct, previously unexplored binding site-a cleft formed at the interface of the N-terminal SH2 and PTP domains. Derivatization of 2 using structure-based design resulted in an increase in SHP2 thermal stabilization, biochemical inhibition, and subsequent MAPK pathway modulation. Downregulation of DUSP6 mRNA, a downstream MAPK pathway marker, was observed in KYSE-520 cancer cells. Remarkably, simultaneous occupation of both allosteric sites by 1 and 2 was possible, as characterized by cooperative biochemical inhibition experiments and X-ray crystallography. Combining an allosteric site 1 inhibitor with an allosteric site 2 inhibitor led to enhanced pharmacological pathway inhibition in cells. This work illustrates a rare example of dual allosteric targeted protein inhibition, demonstrates screening methodology and tactics to identify allosteric inhibitors, and enables further interrogation of SHP2 in cancer and related pathologies.

RESUMEN

Limited research has investigated exercise imagery use in middle-aged and older adults and its relationship with affective and behavioral correlates. The study examined the association between self-regulatory imagery and physical activity (PA) through key social cognitive variables. Middle-aged and older adults (N = 299; M age = 59.73 years, SD = 7.73, range = 50 to 80) completed self-report measures assessing self-regulatory imagery use, self-efficacy, outcome expectations, perceived barriers, self-regulatory behavior, enjoyment, and PA levels. Path analysis supported a model (χ² [14] = 21.76, p = .08, CFI = .99, TLI = .97, SRMR = .03, RMSEA = .04) whereby self-regulatory imagery positively predicted self-efficacy, outcome expectations, and self-regulatory behaviors. Furthermore, self-regulatory imagery indirectly predicted barriers, outcome expectations, self-regulation, enjoyment, and PA. This research highlights self-regulatory imagery as an effective strategy in modifying exercise-related cognitions and behaviors. Incorporating social cognitive constructs into the design of imagery interventions may increase PA engagement.

RESUMEN

The present study aimed to examine whether physical and environment elements of PETTLEP imagery relate to the ability to image five types of sport imagery (i.e. skill, strategy, goal, affect and mastery). Two hundred and ninety participants (152 males, 148 females; Mage = 20.24 years, SD = 4.36) from various sports completed the Sport Imagery Ability Questionnaire (SIAQ), and a set of items designed specifically for the study to assess how frequently participants incorporate physical (e.g. 'I make small movements or gestures during the imagery') and environment (e.g. 'I image in the real training/competition environment') elements of PETTLEP imagery. Structural equation modelling tested a hypothesised model in which imagery priming (i.e. the best fitting physical and environment elements) significantly and positively predicted imagery ability of the different imagery types (skill, ß = 0.38; strategy, ß = 0.23; goal, ß = 0.21; affect, ß = 0.25; mastery, ß = 0.22). The model was a good fit to the data: χ2 (174) = 263.87, p < .001, CFI = .96, TLI = .95, SRMR = .09, RMSEA = 0.05 (90% CI = 0.03-0.05). Findings displayed that priming imagery with physical and environment elements is associated with better skill, strategy, goal, affect and mastery imagery ability. The findings extend models of imagery use by indicating that how athletes images may influence their imagery ability.

RESUMEN

DNA barcoding methods originally developed for the identification of plant specimens have been applied to the authentication of herbal drug materials for industrial quality assurance. These methods are intended to be complementary to current morphological and chemical methods of identification. The adoption of these methods by industry will be accelerated by the introduction of DNA-based identification techniques into regulatory standards and monographs. The introduction of DNA methods into the British Pharmacopoeia is described, along with a reference standard for use as a positive control for DNA extraction and polymerase chain reaction (PCR). A general troubleshooting chart is provided to guide the user through the problems that may be encountered during this process. Nevertheless, the nature of the plant materials and the demands of industrial quality control procedures mean that conventional DNA barcoding is not the method of choice for industrial quality control. The design of DNA barcode-targeted quantitative PCR and high resolution melt curve tests is one strategy for developing rapid, robust, and reliable protocols for high-throughput screening of raw materials. The development of authentication tests for wild-harvested Rhodiola rosea L. is used as a case study to exemplify these relatively simple tests. By way of contrast, the application of next-generation sequencing to create a complete profile of all the biological entities in a mixed herbal drug is described and its potential for industrial quality assurance discussed.

RESUMEN

This study investigated the influence of different types of mental imagery on heart rate and anxiety responses to a standard psychological stress task. Using a within-design, 25 females (Mage=23.24; SD=4.19) imaged three different scripts (challenge, threat, and neutral) to manipulate appraisal of a speech preparation task. Following each script, participants completed the task. Heart rate was recorded during a resting baseline prior to each imagery script and during each speech preparation task. Cognitive and somatic anxiety and self-confidence were assessed prior to the speech preparation trials, and immediately prior to each speech preparation following imagery. Following threat imagery, participants reported the speech preparation task to be significantly more stressful and threatening, and experienced lower levels of confidence and more negative interpretations of their anxiety symptoms compared with the challenge and neutral imagery conditions. Additionally, there was a significantly greater increase in heart rate following threat imagery compared with challenge and neutral imagery. Findings demonstrate that imagery can alter stress appraisal and the accompanying cardiovascular and psychological responses to standardized stress tasks. Imagery interventions, acknowledging the stressful nature of events, but emphasising feelings of efficacy and control are likely to lead to more adaptive coping.

RESUMEN

BACKGROUND AND OBJECTIVES: The aim of the study was to examine habituation of subjective anxiety and electrophysiological correlates of cortical hyper-vigilance during exposure to spider images among high (n = 12) and low (n = 11) spider fear groups. METHODS: Participants viewed a six-stage hierarchy of spider images. The images used at stage 1 and stage 6 were the same. Subjective anxiety was rated at four intervals during each three-minute exposure stage (0, 60, 120, and 180 s) and event-related potentials (ERPs) were averaged across these epochs (0-60, 60-120, 120-180). RESULTS: High spider fearfuls demonstrated greater habituation of self-reported anxiety within and between exposure stages compared to low fearfuls. Consistent with attentional hyper-vigilance, the high-fear group also demonstrated greater P1 amplitude in response to spider images. In both groups, habituation of P1 amplitude was found at later relative to earlier stages, but increased at stage six when the stage 1 image was re-presented, despite low subjective anxiety. LIMITATIONS: While the passive viewing paradigm mirrored image-based exposure, it was not possible to determine whether participants engaged in avoidance strategies. In addition, further research is needed to assess the relevance of habituation and reinstatement of P1 amplitude to therapeutic outcome. CONCLUSIONS: Habituation of subjective anxiety during image-based exposure is not necessarily accompanied by a reduction in measures of cortical hyper-vigilance. The reinstatement of the P1 response may indicate either re-activation of previous associations, less avoidance, or a more generalised dishabituation mechanism.

RESUMEN

Bladder tumors show diverse molecular features and clinical outcome. Muscle-invasive bladder cancer has poor prognosis and novel approaches to systemic therapy are urgently required. Non-muscle-invasive bladder cancer has good prognosis, but high recurrence rate and the requirement for life-long disease monitoring places a major burden on patients and healthcare providers. Studies of tumor tissues from both disease groups have identified frequent alterations of FGFRs, including mutations of FGFR3 and dysregulated expression of FGFR1 and FGFR3 that suggest that these may be valid therapeutic targets. We summarize current understanding of the molecular alterations affecting these receptors in bladder tumors, preclinical studies validating them as therapeutic targets, available FGFR-targeted agents and results from early clinical trials in bladder cancer patients.

RESUMEN

Reducing the maternal mortality rate (MMR) is an important part of Mexico's commitment to the Millennium Development Goals, and the country has made great strides towards achieving this goal. However, researchers have questioned to what extent the focus on improved MMR and other indices of maternal health has contributed to an emphasis on improved statistics rather than quality care, and the effect this has had on the quality of reporting. While public health officials and hospital administrators alike agree that improved obstetric reporting is necessary, there is little discussion regarding the accuracy of the data that are submitted and the institutional pressures that may contribute to the production of inaccurate data. Using ethnographic research collected in Tulum, Quintana Roo, this paper explores how biomedical childbirth functions as a source of legitimization for the state while simultaneously providing the means for the presentation of an ideal subjecthood, one that situates birthing women and healthcare personnel as properly attenuated to the norms and needs of the modern Mexican state. By highlighting the point of disjuncture between women's experiences and the formal 'reality' created through hospital texts, this paper explores the place of biomedical birth as a producer of and legitimization for Mexican public health policy.

RESUMEN

Compelling data suggest that perturbations in microbial colonization of the gut in early-life, influences neurodevelopment and adult brain function. If this is the case, then ensuring the growth of beneficial bacteria at an early age will lead to optimal brain development and maturation. We have tested whether feeding neonatal rats daily (from post-natal days 3-21) with a galacto-oligosaccharide prebiotic (Bimuno®, BGOS) or a control solution, alters the levels of hippocampal N-Methyl-D-Aspartate receptor (NMDAR) subunits (GluN1, GluN2A, GluN2B), synaptic proteins (synaptophysin, MAP2, and GAP43) and brain-derived-neurotrophic factor (BDNF), at post-natal days 22 and 56. The administration of BGOS significantly elevated GluN2A subunits, synaptophysin and BDNF in the hippocampus of 22 day old rats. The effect was also observed on day 56 (26 days after the feeding ceased). The levels of all other proteins (GluN1, GluN2B, MAP2, GAP43) remained unaltered. Increased GluN2A, synaptophysin, BDNF, but not MAP2, may suggest that neonatal BGOS feeding alters neurotransmission rather than synaptic architecture. Although the functional consequences of our findings require further investigation, the current study confirms that the manipulation of gut bacteria in early-life, has central effects that persist until at least young adulthood.
