Nitrogen fixation and fertilization have similar effects on biomass allocation in nitrogen-fixing plants.

Plants adjust their allocation to different organs based on nutrient supply. In some plant species, symbioses with nitrogen-fixing bacteria that live in root nodules provide an alternate pathway for nitrogen acquisition. Does access to nitrogen-fixing bacteria modify plants' biomass allocation? We hypothesized that access to nitrogen-fixing bacteria would have the same effect on allocation to aboveground versus belowground tissues as access to plentiful soil nitrogen. To test this hypothesis and related hypotheses about allocation to stems versus leaves and roots versus nodules, we conducted experiments with 15 species of nitrogen-fixing plants in two separate greenhouses. In each, we grew seedlings with and without access to symbiotic bacteria across a wide gradient of soil nitrogen supply. As is common, uninoculated plants allocated relatively less biomass belowground when they had more soil nitrogen. As we hypothesized, nitrogen fixation had a similar effect as the highest level of fertilization on allocation aboveground versus belowground. Both nitrogen fixation and high fertilization led to ~10% less biomass allocated belowground (~10% more aboveground) than the uninoculated, lowest fertilization treatment. Fertilization reduced allocation to nodules relative to roots. The responses for allocation of aboveground tissues to leaves versus stems were not as consistent across greenhouses or species as the other allocation trends, though more nitrogen fixation consistently led to relatively more allocation to leaves when soil nitrogen supply was low. Synthesis: Our results suggest that symbiotic nitrogen fixation causes seedlings to allocate relatively less biomass belowground, with potential implications for competition and carbon storage in early forest development.

Associations between food insecurity in high-income countries and pregnancy outcomes: A systematic review and meta-analysis.

BACKGROUND: Maternal nutrition is crucial for health in pregnancy and across the generations. Experiencing food insecurity during pregnancy is a driver of inequalities in maternal diet with potential maternal and infant health consequences. This systematic review explored associations between food insecurity in pregnancy and maternal and infant health outcomes. METHODS AND FINDINGS: Searches included 8 databases (MEDLINE, Embase, Scopus, Web of Science, PsychInfo, ASSIA, SSPC in ProQuest, and CINAHL), grey literature, forwards and backwards citation chaining, and contacting authors. Studies in high-income countries (HICs) reporting data on food insecurity in pregnancy and maternal or infant health, from January 1, 2008 to November 21, 2023 were included. Screening, data extraction, and quality assessment were carried out independently in duplicate. Random effects meta-analysis was performed when data were suitable for pooling, otherwise narrative synthesis was conducted. The protocol was registered on PROSPERO (CRD42022311669), reported with PRISMA checklist (S1 File). Searches identified 24,223 results and 25 studies (n = 93,871 women) were included: 23 from North America and 2 from Europe. Meta-analysis showed that food insecurity was associated with high stress level (OR 4.07, 95% CI [1.22, 13.55], I2 96.40%), mood disorder (OR 2.53, 95% CI [1.46, 4.39], I2 55.62%), gestational diabetes (OR 1.64, 95% CI [1.37, 1.95], I2 0.00%), but not cesarean delivery (OR 1.42, 95% CI [0.78, 2.60], I2 56.35%), birth weight (MD -58.26 g, 95% CI [-128.02, 11.50], I2 38.41%), small-for-gestational-age (OR 1.20, 95%, CI [0.88, 1.63], I2 44.66%), large-for-gestational-age (OR 0.88, 95% CI [0.70, 1.12] I2 11.93%), preterm delivery (OR 1.18, 95% CI [0.98, 1.42], I2 0.00%), or neonatal intensive care (OR 2.01, 95% CI [0.85, 4.78], I2 70.48%). Narrative synthesis showed food insecurity was significantly associated with dental problems, depression, anxiety, and maternal serum concentration of perfluoro-octane sulfonate. There were no significant associations with other organohalogen chemicals, assisted delivery, postpartum haemorrhage, hospital admissions, length of stay, congenital anomalies, or neonatal morbidity. Mixed associations were reported for preeclampsia, hypertension, and community/resilience measures. CONCLUSIONS: Maternal food insecurity is associated with some adverse pregnancy outcomes, particularly mental health and gestational diabetes. Most included studies were conducted in North America, primarily the United States of America, highlighting a research gap across other contexts. Further research in other HICs is needed to understand these associations within varied contexts, such as those without embedded interventions in place, to help inform policy and care requirements.

Measuring the association between the opening of a new multi-national restaurant with young people's eating behaviours.

Out-of-home eating (takeaway, take-out and fast-foods) is associated with intakes of higher energy and fat, and lower intakes of micronutrients, and is associated with excess weight gain. In 2017, a unique opportunity arose to measure the association between the opening of a new multi-national fast-food restaurant (McDonald's) and consumption of fast-food on young people aged 11-16. This study uses a repeated cross-sectional design to explore group level change over time with respect to out-of-home eating behaviours of young people. Two secondary schools in Redcar and Cleveland agreed to participate and facilitated the completion of a questionnaire on their pupils eating behaviours at three timepoints a) prior to the new restaurant opening, b) three months post-opening and c) nine months post opening. Reported frequency of visits to McDonald's showed a statistically significant increase in visits between 3 and 9 months of the restaurant opening. This research asks and explores the question of whether the introduction of a new multi-national fast-food restaurant influences eating habits of young people attending schools near the new outlet.

Mycorrhizal associations of temperate forest seedlings mediate rhizodeposition, but not soil carbon storage, under elevated nitrogen availability.

Tree-mycorrhizal associations are associated with patterns in nitrogen (N) availability and soil organic matter storage; however, we still lack a mechanistic understanding of what tree and fungal traits drive these patterns and how they will respond to global changes in soil N availability. To address this knowledge gap, we investigated how arbuscular mycorrhizal (AM)- and ectomycorrhizal (EcM)-associated seedlings alter rhizodeposition in response to increased seedling inorganic N acquisition. We grew four species each of EcM and AM seedlings from forests of the eastern United States in a continuously 13C-labeled atmosphere within an environmentally controlled chamber and subjected to three levels of 15N-labeled fertilizer. We traced seedling 15N uptake from, and 13C-labeled inputs (net rhizodeposition) into, root-excluded or -included soil over a 5-month growing season. N uptake by seedlings was positively related to rhizodeposition for EcM- but not AM-associated seedlings in root-included soils. Despite this contrast in rhizodeposition, there was no difference in soil C storage between mycorrhizal types over the course of the experiment. Instead root-inclusive soils lost C, while root-exclusive soils gained C. Our findings suggest that mycorrhizal associations mediate tree belowground C investment in response to inorganic N availability, but these differences do not affect C storage. Continued soil warming and N deposition under global change will increase soil inorganic N availability and our seedling results indicate this could lead to greater belowground C investment by EcM-associated trees. This potential for less efficient N uptake by EcM-trees could contribute to AM-tree success and a shift toward more AM-dominated temperate forests.

Child Access Prevention Laws and Pediatric Firearm Injury: A Rapid Review.

Introduction: US child firearm fatality rates have risen since 2013. Child Access Prevention (CAP) laws aimed at reducing minors' access to firearms have existed since the 1980s. However, specific requirements for safe storage of firearms, standards of negligence, and penalties for offenders vary significantly by state, yielding a heterogeneous body of CAP legislation. A few studies have investigated the relative impacts of these laws on child firearm injury rates, with sometimes conflicting results. Here, we present a rapid review of the existing literature on CAP laws and their apparent impact on firearm-related injuries among US children, to assess whether CAP laws are an effective tool for reducing child firearm injuries. Methods: We conducted a rapid review of published reports that evaluated the impact of CAP laws on pediatric firearm injuries and/or deaths in the United States. We extracted target population data and outcomes of each study. The data are presented narratively. Results: A total of 14 articles met criteria for evaluation. Taken together, these studies showed that implementation of CAP legislation was associated with reduced pediatric firearm injuries and fatalities. Moreover, longitudinal or time-series studies that examined changes in pediatric firearm injuries pre/post-CAP legislation yielded the most consistent and robust findings. Conclusion: CAP laws were found to be associated with reduced pediatric firearm injuries and deaths, with the magnitude of effect being proportional to CAP law stringency.

Biocompatibility of mussel-inspired water-soluble tissue adhesives.

Wound closure in surgeries is traditionally achieved using invasive methods such as sutures and staples. Adhesion-based wound closure methods such as tissue adhesives, sealants, and hemostats are slowly replacing these methods due to their ease of application. Although several chemistries have been developed and used commercially for wound closure, there is still a need for better tissue adhesives from the point of view of toxicity, wet-adhesion strength, and long-term bonding. Catechol chemistry has shown great promise in developing wet-set adhesives that meet these criteria. Herein, we have studied the biocompatibility of a catechol-based copolymer adhesive, poly([dopamine methacrylamide]-co-[methyl methacrylate]-co-[poly(ethylene glycol) methyl ether methacrylate]) or poly(catechol-MMA-OEG), which is soluble in water. The adhesive was injected subcutaneously in a mouse model on its own and in combination with a sodium periodate crosslinker. After 72 h, 4 weeks, and 12 weeks, the mice were euthanized and subjected to histopathological analysis. Both adhesives were present and still palpable at the end of 12 weeks. The moderate inflammation observed for the poly(catechol-MMA-OEG) cohort at 72 h had reduced to mild inflammation at the end of 12 weeks. However, the moderate inflammatory response observed for the poly(catechol-MMA-OEG) + crosslinker cohort at 72 h had not subsided at 12 weeks.

Congenital anomalies in pregnancies with overt and pregestational type 2 diabetes: a gray portrayal from a cohort in Brazil.

OBJECTIVE: To describe the frequency and types of congenital anomalies and associated risk factors in Brazilian women with type 2 diabetes. METHODS: In this retrospective cohort study between 2005 and 2021, we included all pregnant participants with type 2 diabetes from the two major public hospitals in southern Brazil. We collected data from the electronic hospital records. Congenital anomalies were classified by the 10th revised International Classification of Diseases, Q chapter, enhanced by the EUROCAT registry classification, and categorized by type and gravity. We used multiple Poisson regression with robust estimates to estimate risks. RESULTS: Among 648 participants, we excluded 19, and 62 were lost to follow-up; therefore, we included 567 participants. Overt diabetes arose in 191 participants (33.7%, 95% CI 30.0% - 38.0%). Less than 20% of the participants supplemented folate. Congenital anomalies occurred in 78 neonates (13.8%, CI 11.0 - 16.9%), 73 babies (93.6%) presented major anomalies, and 20 (10.5%) cases occurred in participants with overt diabetes. Cardiac anomalies were the most frequent (43 isolated and 12 combined). Pre-eclampsia was associated with an increased risk in the analyses including all women (adjusted RR 1.87 (95% CI 1.23-2.85), p = 0.003), but not in analyses including only women with an HbA1c measured up to the 14th gestational age. HbA1c, either measured at any time in pregnancy (adjusted RR 1.21 (95% CI 1.10-1.33), p < 0.001) or up to the first 14 weeks (adjusted RR 1.22, 95% CI 1.10-1.35, p < 0.001) was the only sustained risk factor. Risk factors such as maternal age, obesity, diabetes diagnosis, or use of antidiabetic medications were not associated with congenital anomalies. CONCLUSION: We found a high frequency of congenital anomalies associated with poor maternal glycemic control and revealed an almost universal lack of preconception care. An urgent call to action is mandatory for the reversal of this gray scenario.

Bioinductive patch as an augmentation for rotator cuff repair, a systematic review and meta-analysis.

BACKGROUND: Rotator cuff tears are a prevalent cause of shoulder pain and dysfunction. For those who fail initial conservative treatment, operative intervention can be pursued. A significant and common complication after rotator cuff repair (RCR) is retearing or nonhealing. Numerous augmentations to traditional suture RCR have been studied. Of these, the Smith + Nephew Regeneten bioinductive collagen patch has had promising initial results; however, analytic data for its use are lacking, and there is no meta-analysis comparing the available data to historical RCR outcomes. METHODS: A PRISMA-guided literature search was conducted using Ovid MEDLINE, PubMED, Cochrane, and ClinicalTrials.gov. Thirteen studies met inclusion and exclusion criteria. Only clinical trials on full and partial-thickness tears were included. American Shoulder and Elbow Surgeon score, Constant-Murley Score, the visual analog scale for pain, the minimal clinically important difference (MCID), tendon thickness, and complication rates were primary outcomes of interest. A meta-analysis was performed to determine the overall complication and retear rate from the included studies. RESULTS: American Shoulder and Elbow Surgeon score, Constant-Murley Score, and visual analog scale for pain improved significantly in all studies that reported them, and most patients achieved MCID. Patient-reported outcome measure improvements were similar to historical improvements in standard RCR, and a similar proportion of patients achieved MCID after standard repair. Tendon thickness improved significantly and to a similar degree as standard RCR. Overall retear rate after full thickness RCR augmented with the bioinductive patch was 8.3%. For partial thickness RCR, total retear rate was of 1.1% across all patients. The overall complication rate with the bioinductive patch was 15.5% across all full-thickness RCR studies and 16.2% in partial thickness RCR. We found overall retear rate to be lower after augmentation with the bioinductive patch compared to traditional repair; however, the overall complication rate was similar for full-thickness tears and higher for partial-thickness tears. Lastly, adverse reactions to the bioinductive patch were noted at 0.2%. CONCLUSIONS: The bioinductive collagen patch appears to be a safe augmentation for rotator cuff repair. Patients are likely to experience significant subjective improvement in patient-reported outcome measures and significant increases in tendon thickness. Retear rate has been a concern after RCR for decades, and the bioinductive patch may help mitigate this risk. There is lack of case-control studies comparing the bioinductive patch to traditional suture RCR. Such data are needed to better determine the role of the bioinductive patch in the treatment of full and partial-thickness rotator cuff repairs.

International migration, food insecurity, and mental health: A scoping review protocol.

Introduction: Food insecurity is a global priority that has been found to negatively impact mental health, increasing the risk of mental disorders and severe mental illness. International migrants may face food insecurity throughout their migratory cycle due to a range of risk factors, such as poor transit conditions, precarious employment, financial pressure, discrimination, and lack of availability and access to culturally relevant food, among others. Although there are multiple reviews on migration, food insecurity, and health in general, no scoping review has been conducted on food insecurity among international migrants focusing on mental health. Objective: To investigate the available evidence on food insecurity and mental health among international migrants. Methods: A search of scientific literature in English, Spanish, French, Italian, and Portuguese published since 2013 will be performed in the Web of Science, PubMed, Medline, APA PsycArticles, Cinahl, and ASSIA databases, including grey literature available in Google Scholar. Two authors will independently review titles, abstracts, and full texts before extracting data from publications complying with the eligibility criteria. Extracted data will be descriptively mapped according to emerging thematic categories. Expected results: The review will contribute to identifying what is known about international migration, food insecurity, and mental health, gaps in the literature, opportunities for specific research subtopics, and how food insecurity and mental health can be linked in the existing literature.

Food insecurity during pregnancy in high-income countries, and maternal weight and diet: A systematic review and meta-analysis.

Food insecurity is a well-established obesity driver. Less is known about food insecurity during pregnancy. This review (PROSPERO:CRD42022311669) aimed to explore associations between food insecurity, maternal obesity, gestational weight gain (GWG), and nutrition. Searches included seven databases, gray literature, references, citations, and contacting authors. Observational studies reporting data from January 1st, 2008 to 21 November 2023 in high-income countries were included. Duplicate screening, data extraction, and quality assessments were performed. Random effects meta-analysis estimated odds ratios (OR), mean difference (MD), and 95% confidence intervals (CI). Narrative synthesis was conducted when data could not be pooled. Database searches identified 22,272 results; 20 studies were included (n = 19 North America, n = 1 Europe; n = 32,803 women). Food insecurity significantly increased obesity (OR 1.53 95%CI 1.39, 1.66), but not underweight (OR 1.12 95%CI 0.89, 1.34) or overweight (OR 1.18 95%CI 0.90, 1.46). Food insecurity significantly reduced GWG (MD -0.42 kg 95%CI -0.62, -0.22) and increased inadequate GWG (OR 1.16 95%CI 1.05, 1.28), but not excessive GWG (OR 1.04 95%CI 0.96, 1.13). Diet outcomes were inconsistent, with some evidence of reduced vitamin E and diet quality and increased red/processed meat consumption. Further studies outside of North America are needed to inform practice and policy to support maternal health.

Optimizing autologous stem cell collections for patients with multiple myeloma receiving G-CSF and Plerixafor: A single center project.

BACKGROUND: Increasing indications for cellular therapy collections have stressed our healthcare system, with autologous collections having a longer than desired wait time until apheresis collection. This quality improvement initiative was undertaken to accommodate more patients within existing resources. STUDY DESIGN AND METHODS: Patients with multiple myeloma who underwent autologous peripheral blood stem cell collection from October 2022 to April 2023 were included. Demographic, mobilization, laboratory, and apheresis data were retrospectively collected from the medical record. RESULTS: This cohort included 120 patients (49.2% male), with a median age of 60 years. All received G-CSF and 95% received pre-emptive Plerixafor approximately 18 hours pre-collection. Most (79%) had collection goals of at least 8 × 106/kg CD34 cells, with 63% over 70 years old having this high collection goal (despite 20 years of institutional data showing <1% over 70 years old have a second transplant). With collection efficiencies of 55.9%, 44% of patients achieved their collection goal in a single day apheresis collection. A platelet count <150 × 103/µL on the day of collection was a predictor for poor mobilization; among 27 patients with a low baseline platelet count, 17 did not achieve the collection goal and 2 failed to collect a transplantable dose. CONCLUSIONS: With minor collection goal adjustments, 15% of all collection appointments could have been avoided over this 6-month period. Other strategies to accommodate more patients include mobilization modifications (Plerixafor timing or substituting a longer acting drug), utilizing platelet counts to predict mobilization, and modifying apheresis collection volumes or schedule templates.

Carpal tunnel syndrome and sleep, a systematic review and meta-analysis.

BACKGROUND: The most common symptom and reason patients seek treatment for carpal tunnel syndrome is lack of sleep. Our purpose was to determine how much sleep-related symptoms of carpal tunnel syndrome improve after carpal tunnel release using validated patient-reported outcome measures (PROMs) and objective sleep data as primary measures of interest. METHODS: A PRISMA-guided literature search was conducted using Ovid MEDLINE, PubMed, Cochrane, and ClinicalTrials.gov. Only interventional clinical trials that examined primary outcome measures of interest were included. Patient-reported outcome measures underwent meta-analysis to determine how much scores improved following carpal tunnel release. RESULTS: The Pittsburgh Sleep Quality Index improved significantly after carpal tunnel release, by 4.43 points and 6.02 points at 1-3 and 6-12 months postoperatively, respectively, and continued to improve up to 2 years. Improvement on the Insomnia Severity Index after carpal tunnel release was also significant, with improvement up to 1 year postoperatively, by 8.54 points and 9.05 points at 1-3 and 6-12 months, respectively. Insomnia Severity Index scores improved significantly after splinting as well. CONCLUSIONS: The present meta-analysis determined to what extent patients can expect their sleep to improve after operative and non-operative intervention, as measured by various patient-reported outcome measures that assess sleep. The Pittsburgh Sleep Quality Index and Insomnia Severity Index correlated very well between studies and across hundreds of patients with carpal tunnel syndrome. Data are lacking to define the minimal clinically important difference and assess whether patients achieve a minimal clinically important difference for sleep questionnaires; more information on this topic is needed. LEVEL OF EVIDENCE: III.

'Acceleration' of the food delivery marketplace: Perspectives of local authority professionals in the North-East of England on temporary COVID regulations.

In January 2021, we assessed the implications of temporary regulations in the United Kingdom allowing pubs and restaurants to operate on a takeaway basis without instigating a change of use. Local authorities (LAs) across the North-East of England were unaware of any data regarding the take-up of these regulations, partially due to ongoing capacity issues; participants also raised health concerns around takeaway use increasing significantly. One year on, we repeated the study aiming to understand the impact of these regulations on the policy and practice of key professional groups. Specifically, we wanted to understand if LAs were still struggling with staff capacity to address the regulations, whether professionals still had public health trepidations, and if any unexpected changes had occurred across the local food environment because of the pandemic. We conversed with 16 public health professionals, planners and environmental health officers across seven LAs throughout the North-East of England via focus groups and interviews. Data collated were analysed via an inductive and semantic, reflexive-thematic approach. Through analysis of the data, three themes were generated and are discussed throughout: popular online delivery services as a mediator to increased takeaway usage; potential long-term health implications and challenges; continued uncertainty regarding the temporary regulations. This paper highlights important changes to local food environments, which public health professionals should be aware of, so they are better equipped to tackle health inequalities across urban and sub-urban areas.

Food insecurity in adults with severe mental illness living in Northern England: A co-produced cross-sectional study.

AIM: This study aimed to explore food insecurity prevalence and experiences of adults with severe mental illness living in Northern England. METHODS: This mixed-methods cross-sectional study took place between March and October 2022. Participants were adults with self-reported severe mental illness living in Northern England. The survey included demographic, health, and financial questions. Food insecurity was measured using the US Department of Agriculture Adult Food Security measure. Quantitative data were analysed using descriptive statistics and binary logistic regression; and qualitative data using content analysis. RESULTS: In total, 135 participants completed the survey, with a mean age of 44.7 years (SD: 14.1, range: 18-75 years). Participants were predominantly male (53.3%), white (88%) and from Yorkshire (50.4%). The food insecurity prevalence was 50.4% (n = 68). There was statistical significance in food insecurity status by region (p = 0.001); impacts of severe mental illness on activities of daily living (p = 0.02); and the Covid pandemic on food access (p < 0.001). The North West had the highest prevalence of food insecurity (73.3%); followed by the Humber and North East regions (66.7%); and Yorkshire (33.8%). In multivariable binary logistic regression, severe mental illness' impact on daily living was the only predictive variable for food insecurity (odds ratio = 4.618, 95% confidence interval: 1.071-19.924, p = 0.04). CONCLUSION: The prevalence of food insecurity in this study is higher than is reported in similar studies (41%). Mental health practitioners should routinely assess and monitor food insecurity in people living with severe mental illness. Further research should focus on food insecurity interventions in this population.

A nasal cell atlas reveals heterogeneity of tuft cells and their role in directing olfactory stem cell proliferation.

The olfactory neuroepithelium serves as a sensory organ for odors and forms part of the nasal mucosal barrier. Olfactory sensory neurons are surrounded and supported by epithelial cells. Among them, microvillous cells (MVCs) are strategically positioned at the apical surface, but their specific functions are enigmatic, and their relationship to the other specialized epithelial cells is unclear. Here, we establish that the family of MVCs comprises tuft cells and ionocytes in both mice and humans. Integrating analysis of the respiratory and olfactory epithelia, we define the distinct receptor expression of TRPM5+ tuft-MVCs compared with Gɑ-gustducinhigh respiratory tuft cells and characterize a previously undescribed population of glandular DCLK1+ tuft cells. To establish how allergen sensing by tuft-MVCs might direct olfactory mucosal responses, we used an integrated single-cell transcriptional and protein analysis. Inhalation of Alternaria induced mucosal epithelial effector molecules including Chil4 and a distinct pathway leading to proliferation of the quiescent olfactory horizontal basal stem cell (HBC) pool, both triggered in the absence of olfactory apoptosis. Alternaria- and ATP-elicited HBC proliferation was dependent on TRPM5+ tuft-MVCs, identifying these specialized epithelial cells as regulators of olfactory stem cell responses. Together, our data provide high-resolution characterization of nasal tuft cell heterogeneity and identify a function of TRPM5+ tuft-MVCs in directing the olfactory mucosal response to allergens.

Understanding Clinician Knowledge About Race Adjustment in the Vaginal Birth After Cesarean Calculator.

Disparities in maternal health outcomes are striking. Historical and biased clinical support tools have potential to exacerbate inequities. In 2022, NewYork-Presbyterian, with ∼25,000 annual births, and our academic partners, Columbia and Weill Cornell, launched a program to better understand practice patterns and clinician attitudes toward a vaginal birth after cesarean (VBAC) calculator, which predicts VBAC success. This article summarizes the program, focusing on the VBAC calculator utilization survey, which measured provider awareness of the revised calculator and key factors considered in patient counseling. Our preliminary findings warrant future research and education on the calculator's implications for counseling and outcomes.

Food insecurity in adults with severe mental illness: A systematic review with meta-analysis.

INTRODUCTION: Food insecurity in adults living with Severe Mental Illness (SMI) is an underresearched area worldwide. AIM: This systematic review and meta-analysis aimed to identify and collate evidence on food insecurity in adults with SMI, in high- and upper-middle income countries. METHOD: A comprehensive electronic search was completed up to August 2022. Random effects meta-analysis was undertaken to determine the prevalence and the odds ratio for food insecurity in adults with SMI. Narrative synthesis explored the data further. RESULTS: Sixteen publications were included (13 in the meta-analysis). The prevalence estimate of food insecurity in adults with SMI was 41% (95% CI: 29% to 53%, I2 = 99.9%, n = 13). Adults with SMI were 3.31 (95% CI: 2.03 to 5.41) times more likely to experience food insecurity than comparators without SMI (z = 6.29, p < .001, I2 = 98.9%, n = 6). Food insecurity appears to be a risk factor for developing SMI. DISCUSSION: This review suggests adults with SMI living in high- or upper-middle income countries are more likely to experience food insecurity than the general population and that this relationship may be inverse. IMPLICATIONS FOR PRACTICE: Mental health practitioners should be aware of food insecurity and support individuals with SMI to access sufficient food.

Effects of women's age on their emotional eating changes within a self-regulation-focused obesity treatment.

Results of behavioral obesity treatments have generally been unsuccessful. Reduction of participants' emotional eating (EE) might be essential. Women with obesity within age-groups of emerging adult, young adult, and middle-aged adult - participating in a community-based obesity treatment centered around self-regulatory skills to control eating - were evaluated over 6 months. There were significant reductions in participants' EE and eating-related self-regulation. Participants' change in self-regulation significantly predicted their changes in depression-related, anxiety-related, and total EE. Participants' age group did not significantly affect either their degree of improvement or self-regulation-EE change relationships. Emphasizing self-regulatory skills development for the control of EE, regardless of age-group in women, was suggested by the study authors.

Process evaluation of a primary care-based type 2 diabetes remission project in the North East of England.

A type 2 diabetes remission project, Remission in Diabetes (REMI.D), funded by Sport England, was developed by stakeholders based in the North East of England and begun in early 2020. This local delivery pilot sought to tackle health inequalities by working with multiple organisations to demonstrate a way of scaling up an effective type 2 diabetes remission strategy which included both physical activity and dietary components. The intended delivery of the original project was impacted by the COVID-19 pandemic and changes were made to the project delivery in 2022. The aim of this process evaluation was to learn from the reactive decisions taken by stakeholders which altered the REMI.D project in response to the COVID-19 pandemic. Twelve stakeholders (from local authorities, secondary care, universities, NHS England commissioning, Diabetes UK, Sport England, Everyone Active and Active Partnerships) involved in the design and delivery of the intervention took part in a semi-structured interview lasting up to 60 min. Interviews were recorded and transcribed verbatim. Thematic analysis used the pre-determined 'core content' themes from the Medical Research Council and National Institute for Health Research framework for developing and evaluating complex interventions. Three topics for discussion emerged as follows: (a) lack of effective collaboration, (b) perception of change and (c) scalability of the intervention. Hierarchy within the stakeholder group initially hampered collaboration. Change was reactive as a result of the COVID-19 pandemic. Project changes reduced project sustainability and scalability but offered valuable learning about the need for explicit project theory for partnership working, co-production with service users and project flexibility for long-term health behaviour change.
