• Care-experienced young people experience high levels of mental health problems. • System resources, cultures and stakeholder values, impact interventions. • Care-experienced young people valued meaningful relationships in interventions. • Carers felt interventions often overlooked their expertise and experiences. • Future interventions should support carers' time and emotional commitment. The mental health and well-being of care-experienced children and young people remains a concern. Despite a range of interventions, the existing evidence base is limited in scope, with a reliance on standalone outcome evaluations which limits understanding of how contextual factors influence implementation and acceptability. The Care-experienced cHildren and young people's Interventions to improve Mental health and wEll-being outcomes Systematic review (CHIMES) aimed to synthesise evidence of intervention theory, outcome, process and economic effectiveness. This paper reports the process evaluation synthesis, exploring how system factors facilitate and inhibit implementation and acceptability of mental health and wellbeing interventions for care-experienced children and young people. Sixteen databases and 22 websites were searched between 2020 and 2022 for studies published from 1990 and May 2022. This was supplemented with contacting experts in the field, citation tracking, screening of relevant systematic reviews and stakeholder consultations. We drew on framework synthesis of qualitative data and incorporated a systems lens, taking account of contextual influences across socio-ecological domains. Quality appraisal assessed reliability and usefulness. Confidence in synthesised findings was assessed with the GRADE-CERQual tool. We report the review in accordance with relevant elements of both the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA), and the Enhancing transparency in reporting the synthesis of qualitative research (ENTREQ) checklist. Searches retrieved 15,068 unique study reports, and 23 of these were eligible for process evaluation synthesis, reporting on sixteen interventions. Studies were published between 2003 and 2021. Nine interventions were from the UK and Ireland, six interventions were from the USA, and one was from Australia. They were largely classified as interpersonal, where the aim was to modify carer-child relationships. Five key context factors were identified that supported and prohibited intervention delivery: (1) lack of system resources; (2) intervention burden, which encompasses the time, cognitive, and emotional burden associated with implementation and participation; (3) interprofessional relationships between health and social care professionals; (4) care-experienced young people's identity; and (5) carer identity. We identified several supportive and restrictive factors across social and health care systems that may impact intervention implementation and acceptability. Key implications include: the importance of involving diverse stakeholders in intervention development and delivery; the need to better resource and support those involved in interventions, particularly training and support for carers; and ensuring future evaluations integrate process evaluations in order to optimise interventions.

Background Better tools are needed to diagnose and identify children at risk of clinical malnutrition. Objectives We aimed to compare body composition (BC) and malnutrition screening tools (MSTs) for detecting malnutrition on admission; and examine their ability to predict adverse clinical outcomes [increased length of stay (LOS) and complications] in complex pediatric patients. Methods This was a prospective study in children 5–18 y old admitted to a tertiary pediatric hospital (n = 152). MSTs [Pediatric Yorkhill Malnutrition Score (PYMS), Screening Tool for the Assessment of Malnutrition in Pediatrics (STAMP), and Screening Tool for Risk of Impaired Nutritional Status and Growth (STRONGkids)] were completed on admission. Weight, height, and BC [fat mass (FM) and lean mass (LM) by DXA] were measured (n = 118). Anthropometry/BC and MSTs were compared with each other and with clinical outcomes. Results Subjects were significantly shorter with low LM compared to reference data. Depending on the diagnostic criteria used, 3%–17% were classified as malnourished. Agreement between BC/anthropometric parameters and MSTs was poor. STAMP and STRONGkids identified children with low weight, LM, and height. PYMS, and to a lesser degree STRONGkids, identified children with increased LOS, as did LM compared with weight or height. Patients with complications had lower mean ± SD LM SD scores (−1.38 ± 1.03 compared with −0.74 ± 1.40, P < 0.05). In multivariable models, PYMS high risk and low LM were independent predictors of increased LOS (OR: 3.76; 95% CI: 1.36, 10.35 and OR: 3.69; 95% CI: 1.24, 10.98, respectively). BMI did not predict increased LOS or complications. Conclusions LM appears better than weight and height for predicting adverse clinical outcomes in this population. BMI was a poor diagnostic parameter. MSTs performed differently in associations to BC/anthropometry and clinical outcomes. PYMS and LM provided complementary information regarding LOS. Studies on specific patient populations may further clarify the use of these tools and measurements. [ABSTRACT FROM AUTHOR]

- Abstract
Summary Background & aims Infants with complex medical conditions often display faltering growth due to elevated nutritional requirements, poor intake and intolerance of feeding with malabsorption and maldigestion. As a result their nutritional management can be extremely challenging and enteral nutritional support is required. This study aimed to investigate the effectiveness, tolerance and acceptability of nutritional support with a specially formulated, paediatric peptide feed in infants with complex disease and signs of growth faltering with their current nutritional management. Methods This prospective intervention study investigated gastrointestinal (GI) tolerance, nutritional intake and compliance with feeding, anthropometry and growth in 18 infants (mean age 6.11 months ± 4.69, mean weight 4.97 kg ± 1.71) during 28 days of enteral nutritional support with a paediatric (1 kcal/ml) readymade peptide feed. Results GI tolerance to nutritional support with a peptide enteral feed was good and either improved or remained stable over the study. Compliance was excellent (94.0% ± 12.6), total energy intake improved (+23 ± 42 kcal/kg, p = 0.037) and mean weight (0.61 kg ± 0.31, p = 0.0001), length (1.89 ± 1.77 cm, p = 0.0001), head circumference (1.33 ± 1.29 cm, p = 0.001), weight for length Z score ( p < 0.05), and weight for age Z score ( p < 0.05) significantly improved. Sixty one percent (n = 11) of the infants showed signs of increased growth velocity, moving upwards in terms of their centiles. All 18 infants continued with the paediatric, peptide enteral feed once the study was complete. Conclusions This prospective study showed that nutrition support with a specially formulated, paediatric peptide readymade feed was well tolerated, helped to promote growth, and can be considered suitable for use in infants with complex disease and faltering growth who are unable to tolerate a whole protein feed.

EIMERIA , *APICOMPLEXA , *COCCIDIOSIS in animals , *ANIMAL welfare , *CHICKENS - Abstract
The phylum Apicomplexa includes parasites of medical, zoonotic and veterinary significance. Understanding the global distribution and genetic diversity of these protozoa is of fundamental importance for efficient, robust and long-lasting methods of control. Eimeria spp. cause intestinal coccidiosis in all major livestock animals and are the most important parasites of domestic chickens in terms of both economic impact and animal welfare. Despite having significant negative impacts on the efficiency of food production, many fundamental questions relating to the global distribution and genetic variation of Eimeria spp. remain largely unanswered. Here, we provide the broadest map yet of Eimeria occurrence for domestic chickens, confirming that all the known species ( Eimeria acervulina , Eimeria brunetti , Eimeria maxima , Eimeria mitis , Eimeria necatrix , Eimeria praecox , Eimeria tenella ) are present in all six continents where chickens are found (including 21 countries). Analysis of 248 internal transcribed spacer sequences derived from 17 countries provided evidence of possible allopatric diversity for species such as E. tenella (F ST values ⩽0.34) but not E. acervulina and E. mitis , and highlighted a trend towards widespread genetic variance. We found that three genetic variants described previously only in Australia and southern Africa (operational taxonomic units x, y and z) have a wide distribution across the southern, but not the northern hemisphere. While the drivers for such a polarised distribution of these operational taxonomic unit genotypes remains unclear, the occurrence of genetically variant Eimeria may pose a risk to food security and animal welfare in Europe and North America should these parasites spread to the northern hemisphere.

Background: Children with chronic intestinal failure (IF) treated with long-term parenteral nutrition (PN) may present with low bone mineral density (BMD). The cause may reflect small body size or suboptimal bone mineralization. Objective: We assessed growth and bone health in children with severe IF. Design: Height, weight, and fracture history were recorded. The lumbar spine bone mass was measured in 45 consecutive patients (24 male subjects) aged 5-17 y receiving PN for a median of 5 y. BMD and bone mineral apparent density (BMAD) [ie, adjusted-for-height SD scores (SDSs)] were calculated. Results: Diagnoses were short bowel syndrome in 12 patients (27%), intestinal enteropathy in 20 patients (44%), and motility disorder in 13 patients (29%). Mean (±SD) weight, height, and body mass index SDSs were -0.8 ± 1.3, -1.80 ± 1.5, and 0.4 ± 1.3, respectively. The height SDS was less than -2 in 23 children (50%). Patients with enteropathy or intestinal mucosal inflammation (associated with dysmotility or short bowel) were significantly shorter than patients without enteropathy (P = 0.007). The BMD SDS was -1.7 ± 1.6, and the BMAD SDS was -1.4 ± 1.5, independent of primary diagnosis or mucosal inflammation. Nineteen patients (42%) had low BMD (SDS less than -2.0), and 14 patients (31%) had low BMAD. In 25 patients studied at 1-2-y intervals, the BMD SDS fell significantly with time, whereas BMAD declined less, which suggested that a poor bone mineral accretion reflected poor growth. A total of 11 of 37 patients (24%) had nonpathologic fractures (P = 0.3 compared with the general population). Conclusions: Approximately 50% of children were short, and one-third of children had low BMD and BMAD. Children with enteropathy or intestinal mucosal inflammation are at greatest risk of growth failure. Close nutritional monitoring and bespoke PN should maximize the potential for growth and bone mass. [ABSTRACT FROM AUTHOR]

Abstract: Purpose: Our aim was to determine incidence, severity, and outcome, as well as predisposing factors and underlying diagnoses, of intestinal failure-associated liver disease (IFALD) in surgical infants requiring long-term parenteral nutrition (PN). Methods: We retrospectively studied surgical infants receiving PN for at least 28 days for congenital or acquired intestinal anomalies over a 5-year period (January 2006 to December 2010). Intestinal failure-associated liver disease was defined as type 1 (early)—persistent elevation of alkaline phosphatase for 6 weeks or longer; type 2 (established)—additional elevated total bilirubin (≥50 μmol/L); and type 3 (late)—additional clinical signs of end-stage liver disease. Results: Eighty-seven infants required PN for at least 28 days. Intestinal failure-associated liver disease occurred in 29 infants (33%). Intestinal failure-associated liver disease was managed medically in all but 2 patients who underwent intestinal elongation. None were referred for intestinal or liver transplant. Intestinal failure-associated liver disease has been reversed in 17 (59%) of cases to date. Sixty-one children receiving long-term PN (70%) have achieved enteral autonomy, whereas 12 (14%) require home PN. Severity of IFALD was significantly associated with duration of PN and female sex. Conclusion: Intestinal failure-associated liver disease remains a fairly common but rarely life-threatening complication of intestinal failure in surgical infants. Intestinal failure-associated liver disease can be reversed in more than half of these children, and enteral autonomy was achieved in more than two thirds, even with minimal use of intestinal elongation. This is the first study to demonstrate an association between the severity of IFALD in surgical infants and female sex. [Copyright &y& Elsevier]

Abstract: The ability to track cells in small-animal models of human disease is important because it gives the potential to improve our understanding of the processes of disease progression as well as our understanding of the therapeutic effects of interventions. In this study gold nanoparticles have been used as a permanent marker of implanted normal and malignant cell grafts in combination with a suitable x-ray apparatus. Using x-ray computed tomography the micrometric three-dimensional distribution of these marked cells could be displayed with penetration depth, high cell sensitivity and high spatial resolution in rodent models of human diseases. In principle the method allows quantification of cell numbers at any anatomical location over time in small animals. From the Clinical Editor: In this paper, a gold nanoparticle based cell labeling method is presented for in vivo cell tracking via micro-CT. Although a tumor model is shown in this pilot experiment, the method can theoretically be utilized in cell labeling experiments of any kind. [Copyright &y& Elsevier]

Objective: The purpose of this study was to determine the influence of planned mode and planned timing of delivery on neonatal outcomes in infants with gastroschisis.Study Design: Data from the Canadian Pediatric Surgery Network cohort were used to identify 519 fetuses with isolated gastroschisis who were delivered at all tertiary-level perinatal centers in Canada from 2005-2013 (n = 16). Neonatal outcomes (including length of stay, duration of total parenteral nutrition, and a composite of perinatal death or prolonged exclusive total parenteral nutrition) were compared according to the 32-week gestation planned mode and timing of delivery with the use of the multivariable quantile and logistic regression.Results: Planned induction of labor was not associated with decreased length of stay (adjusted median difference, -2.6 days; 95% confidence interval [CI], -9.9 to 4.8), total parenteral nutrition duration (adjusted median difference, -0.2 days; 95% CI, -6.4 to 6.0), or risk of the composite adverse outcome (relative risk, 1.7; 95% CI, 0.1-3.2) compared with planned vaginal delivery after spontaneous onset of labor. Planned delivery at 36-37 weeks' gestation was not associated with decreased length of stay (adjusted median difference, 5.9 days; 95% CI, -5.7 to 17.5), total parenteral nutrition duration (adjusted median difference, 3.2 days; 95% CI, -7.9 to 14.3), or risk of composite outcome (relative risk, 2.3; 95% CI, 0.8-5.4) compared with planned delivery at ≥38 weeks' gestation.Conclusion: Infants with gastroschisis who were delivered after planned induction or planned delivery at 36-37 weeks' gestation did not have significantly better neonatal outcomes than planned vaginal delivery after spontaneous onset of labor and planned delivery at ≥38 weeks' gestation.

Coccidiosis caused by Eimeria species is an important disease worldwide, particularly in ruminants and poultry. Eimeria infection can result in significant economic losses due to costs associated with treatment and slower growth rates, or even with mortality of heavily infected individuals. In goat production, a growing industry due to increasing demand for caprine products worldwide, coccidiosis is caused by several Eimeria species with E. arloingi and E. ninakohlyakimovae the most pathogenic. The aims of this study were genetic characterization of a newly isolated European E. arloingi strain (A) and determination of phylogenetic relationships with Eimeria species from other ruminants. Therefore, a DNA sequence of E. arloingi strain (A) containing 2290 consensus nucleotides (the majority of 18S rDNA, complete ITS-1 and 5.8S sequences, and the partial ITS-2) was amplified and phylogenetic relationship determined with the most similar sequences available on GenBank. The phylogenetic tree presented a branch constituted by bovine Eimeria species plus E. arloingi , and another one exclusively populated by ovine Eimeria species. Moreover, E. arloingi , E. bovis and E. zuernii , which all replicate in host intestinal endothelial cells of the lacteals, were found within the same cluster. This study gives new insights into the evolutionary phylogenetic relationships of this newly described caprine Eimeria strain and confirmed its close relationship to other highly pathogenic ruminant Eimeria species characterized by macromeront formation in host endothelial cells of the central lymph capillaries of the small intestine.

Background: To assess the efficacy, safety, and predictors for poor responsiveness of botulinum toxin type A (BoNT-A) for chronic migraine in the adolescent and young adult population.Methods: A retrospective analysis of 56 patients who received BoNT-A for chronic migraine with an age range from 13 to 21 years was performed. Of 56 patients, 34 were enrolled in the study based on the inclusion criterion. Patients who received three dosages of BoNT-A were assessed at nine months from the first injection. Variables including age, body mass index, headache intensity, frequency, character, and side effects were assessed. The patients were divided into two groups based on response to BoNT-A therapy, responders and nonresponders.Results: Overall among the 34 patients enrolled in the study, the average headache frequency decreased from 18.6 of 28 to 9.9 of 28 days, P value, <0.001 from baseline. There was significant decrease in the average headache intensity, 8.1 to 4.3. Of 34 patients, 25 (73%) patients responded to treatment with decrease in headache frequency by ≥ 50% from the baseline. Among the nonresponder patients, a significant number of patients (six of nine, 67%) had generalized anxiety disorder with Generalized Anxiety Disorder-7 score greater than 15 versus the responder group (six of 25, 24%, P value 0.040).Conclusions: BoNT-A remains a safe and effective therapy for adolescent and young adult patients with chronic migraines at nine months of follow-up. Generalized anxiety disorder with Generalized Anxiety Disorder-7 score greater than 15 can be a major predictor of poor response to this therapy. [ABSTRACT FROM AUTHOR]- Published

Abstract: Agriculture faces unique challenges as increasing world population places unprecedented demands on food, feed, and energy resources. In an effort to become more efficient and sustainable, marginal land, including regulatory brownfields prohibited for food consumption purposes could be utilized for bioenergy crop production. In 2006–2008, we evaluated soybean (Glycine Max (L.) Merr.), canola (Brassica napus L. var. napus), sunflower (Helianthus annuus L.), and switchgrass (Panicum virgatum L.) to determine crop suitability for bioenergy production on a regulatory brownfield site. Sites selected for the study included a remediated brownfield site in Rose Township, Oakland County, and a historically cropped agricultural site at East Lansing, Ingham County, serving as the control. Comparisons of biofuel quality components were conducted. The total oil yield of oilseed crops was not significantly different (p < 0.05) between locations. Concentrations of palmitic (C16:0), stearic (C18:0), oleic (C18:1), linoleic (C18:2), and linolenic (C18:3) fatty acids differed by location, yet oleic acid concentrations, optimal for quality biodiesel production, were not significantly different across all oilseed crops. Total crystalline cellulose levels from switchgrass were higher at the agricultural land site compared to the brownfield site in 2007 yielding 16% more crystalline cellulose; but there were no differences between locations in 2008. Detectable levels of PCB''s were found in soils at the brownfield site; however, transfer to grain or biomass was not detected. Results suggest that brownfield sites have the potential to produce feedstock of suitable quality for conversion to liquid transportation fuels. [Copyright &y& Elsevier]

Background Second generation antipsychotic medications (SGAs) are widely used by reproductive-age women to treat a number of psychiatric illnesses. Some SGAs have been associated with an increased risk of developing diabetes, although information regarding their diabetogenic effect in pregnant women is scarce. Objective To evaluate the risk of gestational diabetes (GDM) among women treated with SGA. Method The Massachusetts General Hospital (MGH) National Pregnancy Registry for Atypical Antipsychotics (NPRAA) collects data on drug use, pregnancy outcomes, and other characteristics from pregnant women, ages 18–45 years, using 3 phone interviews conducted at (1) enrollment during pregnancy, (2) 7 months' gestation, and (3) 2–3 months postpartum. Information on GDM was abstracted from obstetric and delivery medical records. The study population was restricted to women without pre-gestational diabetes. Pregnancies exposed to SGAs during the first trimester were compared with a reference group of women with psychiatric conditions but not treated with SGAs during pregnancy. Generalized linear models were used to estimate adjusted odds ratios (OR) and 95% confidence intervals (CI) for GDM. Results Of 303 women exposed to SGAs, 33 (10.9%) had GDM compared to 16 (10.7%) in the 149 non-exposed women. The crude OR of GDM for SGA was 1.02 (95% CI, 0.54–1.91). After adjustment for maternal age, race, marital status, employment status, level of education, smoking, and primary psychiatric diagnosis, the OR moved to 0.79 (0.40–1.56). Conclusions Findings did not suggest an increased risk of GDM associated with exposure to SGAs during pregnancy in women who had used SGA before pregnancy without developing diabetes, compared to psychiatrically ill women who were not exposed to SGA.

A class of anti-virulence compounds, the salicylidene acylhydrazides, has been widely reported to block the function of the type three secretion system of several Gram-negative pathogens by a previously unknown mechanism. In this work we provide the first identification of bacterial proteins that are targeted by this group of compounds. We provide evidence that their mode of action is likely to result from a synergistic effect arising from a perturbation of the function of several conserved proteins. We also examine the contribution of selected target proteins to the pathogenicity of Yersinia pseudotuberculosis and to expression of virulence genes in Escherichia coli O157. [ABSTRACT FROM AUTHOR]
