RESUMEN

The Ovarian-Adnexal Reporting and Data System (O-RADS) is an evidence-based clinical support system for ovarian and adnexal lesion assessment in women of average risk. The system has both US and MRI components with separate but complementary lexicons and assessment categories to assign the risk of malignancy. US is an appropriate initial imaging modality, and O-RADS US can accurately help to characterize most adnexal lesions. MRI is a valuable adjunct imaging tool to US, and O-RADS MRI can help to both confirm a benign diagnosis and accurately stratify lesions that are at risk for malignancy. This article will review the O-RADS US and MRI systems, highlight their similarities and differences, and provide an overview of the interplay between the systems. When used together, the O-RADS US and MRI systems can help to accurately diagnose benign lesions, assess the risk of malignancy in lesions suspicious for malignancy, and triage patients for optimal management.

RESUMEN

Preventing childhood obesity from early life is considered essential. However, evidence from recent systematic reviews has highlighted inconsistent results and limited effectiveness of preconception and pregnancy lifestyle interventions regarding offspring weight outcomes and adiposity. Therefore, to improve our understanding regarding the mixed success of these early life interventions, we conducted a scoping review examining intervention complexity, process evaluation components, and authors' statements. Eligible articles (preconception or pregnancy lifestyle trials with offspring data beyond 1 month of age) were identified by searching databases (PubMed, Embase, and CENTRAL), previous reviews, and performing CLUSTER searches. The Intervention Complexity Assessment Tool for Systematic Reviews (iCAT_SR) was used to evaluate intervention complexity. A thematic analysis provided insight into process evaluation components and authors' interpretations. Finally, an expert consultation on the results was conducted. We identified 40 eligible publications corresponding to 27 trials. Only two trials started before conception. Potential reasons for interventions' limited success included the late intervention initiation, short intervention duration, and insufficient sample size. Few studies reported process evaluations and included stakeholder involvement, which are essential according to the expert group. We discuss current limitations and outline suggestions for future interventions in this field of research.

RESUMEN

BACKGROUND: Childhood represents a critical period of nutritional risk in the programming of later chronic disease. Few longitudinal studies have explored repeated measures of nutrition throughout the first decade of life in relation to preteen cardiometabolic outcomes. OBJECTIVES: This research aimed to explore associations of early feeding practices (human milk exposure and duration and timing of introduction to solids) and childhood dietary quality and inflammatory scores (at 5 and 9-11 y and change during childhood) on preteen cardiometabolic outcomes. METHODS: This is an analysis of children from the ROLO longitudinal birth cohort study (n = 399). Information on early feeding practices were obtained at postnatal study visits. Food frequency questionnaires collected maternal-reported dietary intakes for each child at 5 and 9-11 y of age. Healthy Eating Index (HEI)-2015 and the Children's Dietary Inflammatory Index (C-DII) scores were calculated. Anthropometry, body composition, blood pressure, heart rate, cardiorespiratory endurance, and blood biomarkers were obtained at 9-11 y. Crude and adjusted linear regression models examined nutritional exposure associations with preteen cardiometabolic outcomes. RESULTS: In the adjusted model, any human milk exposure was associated with lower body fat (%) at 9-11 y (ß: -2.86; 95% confidence interval [CI]: -5.46, -0.27; P = 0.03), than never receiving human milk. At 5 y, diet scores were favorably associated with lean mass at 9-11 y (P < 0.05 for both). Higher preteen HEI-2015 scores were associated with lower preteen leptin levels (tertile 3 compared with tertile 1-ß: -2.92; 95% CI: -5.64, -0.21; P = 0.03). Diet quality significantly deteriorated (HEI-2015 score decreased) and became more proinflammatory (C-DII score increased) from 5 to 9-11 y of age. Diet quality/inflammation deterioration (compared with improvement) or overall change in dietary scores were not related to preteen cardiometabolic outcomes. CONCLUSIONS: Exposure to human milk in early life was associated with lower preteen adiposity, irrespective of duration. Diet quality/inflammatory potential deteriorated between early childhood and the preteen years, highlighting a potential period for intervention.

RESUMEN

BACKGROUND AND AIMS: Studies have consistently demonstrated associations between ultra-processed food and drink (UPFD) consumption and non-communicable diseases. However, there is a lack of data investigating relationships between UPFD intake and intermediate cardiometabolic disease markers. In this study we explored UPFD associations with lipoprotein subclasses. METHODS: This was a cross-sectional study of 1986 middle-to older-aged men and women randomly selected from a large primary care centre. The percentage contribution of UPFDs to total energy intake was calculated for each participant using the NOVA classification. Lipoprotein particle subclass concentrations and size were determined using nuclear magnetic resonance spectroscopy. Correlation and multivariate-adjusted linear regression analyses were performed to examine UPFD intake relationships with lipoprotein subclasses. RESULTS: In fully adjusted regression models, higher UPFD consumption was associated with reduced high-density lipoprotein (HDL) cholesterol concentrations (ß = -0.024, p = 0.001), large low-density lipoprotein (LDL) levels (ß = -18.645, p = 0.002), total and medium HDL concentrations (ß = -0.328, p = 0.012; ß = -0.510, p < 0.001), smaller LDL and HDL size (ß = -0.026, p = 0.023; ß = -0.023, p = 0.024), and increased medium very low-density lipoprotein levels (ß = 0.053, p = 0.022), small LDL and HDL concentrations (ß = 20.358, p = 0.02; ß = 0.336, p = 0.011), and higher lipoprotein insulin resistance scores (ß = 0.048, p = 0.012), reflecting greater lipoprotein-related insulin resistance. CONCLUSIONS: Findings from this research suggest that increased intake of UPFDs is associated with a more pro-atherogenic, insulin-resistant metabolic profile in middle-to older-aged adults which may be a potential mechanism underlying reported associations between UPFD consumption and chronic disease risk and mortality.

RESUMEN

BACKGROUND AND AIMS: Lipoprotein particle concentrations and size are associated with increased risk for atherosclerosis and premature cardiovascular disease. Certain dietary behaviours may be cardioprotective and public health strategies are needed to guide consumers' dietary choices and help prevent diet-related disease. The Food Standards Agency nutrient profiling system (FSAm-NPS) constitutes the basis of the five-colour front-of-pack Nutri-Score labelling system. No study has examined FSAm-NPS index associations with a wide range of lipoprotein particle subclasses. METHODS: This was a cross-sectional study of 2006 middle-to older-aged men and women randomly selected from a large primary care centre. Individual participant FSAm-NPS dietary scores were derived from validated food frequency questionnaires. Lipoprotein particle subclass concentrations and size were determined using nuclear magnetic resonance spectroscopy. Multivariate-adjusted linear regression analyses were performed to examine FSAm-NPS relationships with lipoprotein particle subclasses. RESULTS: In fully adjusted models which accounted for multiple testing, higher FSAm-NPS scores, indicating poorer dietary quality, were positively associated with intermediate-density lipoprotein (ß = 0.096, p = 0.005) and small high-density lipoprotein (HDL) (ß = 0.492, p = 0.006) concentrations, a lipoprotein insulin resistance score (ß = 0.063, p = 0.02), reflecting greater lipoprotein-related insulin resistance, and inversely associated with HDL size (ß = -0.030, p = 0.045). CONCLUSIONS: A higher FSAm-NPS score is associated with a less favourable lipoprotein particle subclass profile in middle-to older-aged adults which may be a potential mechanism underlying reported health benefits of a healthy diet according to Nutri-Score rating.

RESUMEN

Ultrasound (US) is the imaging modality of choice for evaluation of superficial palpable lesions. A large proportion of these lesions have characteristic sonographic appearance and can be confidently diagnosed with US without the need for biopsy or other intervention. The Society of Radiologists in Ultrasound (SRU) recently published a Consensus Conference Statement on superficial soft tissue masses. The goal of this manuscript is (a) to serve as a sonographic pictorial review for palpable lesions based on the SRU statement, (b) present the typical sonographic features of palpable lesions that can be confidently diagnosed with US, and (c) provide an overview of other palpable lesions with a framework to interpret the US studies and advise on appropriate further management.

RESUMEN

PURPOSE: Metabolic health phenotypes exist across the body mass index spectrum. Diet may be an important modifiable risk factor, yet limited research exists on dietary patterns in this context. We investigated associations between dietary patterns, reflecting dietary quality, healthfulness and inflammatory potential, and metabolic health phenotypes in adults living with and without obesity. METHODS: This cross-sectional study included 2,040 middle- to older-aged men and women randomly selected from a large primary care centre. The Dietary Approaches to Stop Hypertension score, Healthy Eating Index, Dietary Inflammatory Index, overall, healthful and unhealthful plant-based dietary indices and Nutri-Score were derived from validated food frequency questionnaires. Descriptive and logistic regression analyses were used to examine diet score relationships with metabolic health phenotypes (Metabolically Healthy/Unhealthy Obese (MHO/MUO) and Non-Obese (MHNO/MUNO)), defined using three separate metabolic health definitions, each capturing different aspects of metabolic health. RESULTS: In fully adjusted models, higher unhealthful plant-based dietary scores were associated with a lower likelihood of MHO (OR = 0.96, 95% CI: 0.93-1.00, p = 0.038) and MHNO (OR = 0.97, 95% CI: 0.95-0.99, p = 0.006). Higher Nutri-Score values were associated with an increased likelihood of MHNO (OR = 1.06, 95% CI: 1.01-1.13, p = 0.033). CONCLUSION: These findings provide evidence that more unhealthful plant-based diets may be linked with unfavourable metabolic health status, irrespective of BMI.

RESUMEN

Background/objectives: The Family Nurse Partnership is an intensive home visiting programme for adolescent mothers. We aimed to evaluate the effectiveness of the Family Nurse Partnership on outcomes up to age 7 using national administrative data. Design: We created a linked cohort of all mothers aged 13-19 using data from health, educational and children's social care and defined mothers enrolled in the Family Nurse Partnership or not using Family Nurse Partnership system data. Propensity scores were used to create matched groups for analysis. Setting: One hundred and thirty-six local authorities in England with active Family Nurse Partnership sites between 2010 and 2017. Participants: Mothers aged 13-19 at last menstrual period with live births between April 2010 and March 2019, living in a Family Nurse Partnership catchment area and their firstborn child(ren). Interventions: The Family Nurse Partnership includes up to 64 home visits by a family nurse from early pregnancy until the child's second birthday and is combined with usual health and social care. Controls received usual health and social care. Main outcome measures: Indicators of child maltreatment (hospital admissions for injury/maltreatment, referral to social care services); child health and development (hospital utilisation and education) outcomes and maternal hospital utilisation and educational outcomes up to 7 years following birth. Data sources: Family Nurse Partnership Information System, Hospital Episode Statistics, National Pupil Database. Results: Of 110,520 eligible mothers, 25,680 (23.2%) were enrolled in the Family Nurse Partnership. Enrolment rates varied across 122 sites (range: 11-68%). Areas with more eligible mothers had lower enrolment rates. Enrolment was higher among mothers aged 13-15 (52%), than 18-19 year-olds (21%). Indicators of child maltreatment: we found no evidence of an association between the Family Nurse Partnership and indicators of child maltreatment, except for an increased rate of unplanned admissions for maltreatment/injury-related diagnoses up to age 2 for children born to Family Nurse Partnership mothers (6.6% vs. 5.7%, relative risk 1.15; 95% confidence interval 1.07 to 1.24). Child health and developmental outcomes: there was weak evidence that children born to Family Nurse Partnership mothers were more likely to achieve a Good Level of Development at age 5 (57.5% vs. 55.4%, relative risk 1.05; 95% confidence interval 1.00 to 1.09). Maternal outcomes: There was some evidence that Family Nurse Partnership mothers were less likely to have a subsequent delivery within 18 months of the index birth (8.4% vs. 9.3%, relative risk 0.92; 95% confidence interval 0.88 to 0.97). Younger and more vulnerable mothers received higher numbers of visits and were more likely to achieve fidelity targets. Meeting the fidelity targets was associated with some outcomes. Limitations: Bias by indication and variation in the intervention and usual care over time and between areas may have limited our ability to detect effects. Multiple testing may have led to spurious, significant results. Conclusions: This study supports findings from evaluations of the Family Nurse Partnership showing no evidence of benefit for maltreatment outcomes measured in administrative data. Amongst all the outcomes measured, we found weak evidence that the Family Nurse Partnership was associated with improvements in child development at school entry, a reduction in rapid repeat pregnancies and evidence of increased healthcare-seeking in the mother and child. Future work: Future evaluations should capture better measures of Family Nurse Partnership interventions and usual care, more information on maternal risk factors and additional outcomes relating to maternal well-being. Study registration: The study is registered as NIHR CRN Portfolio (42900). Funding: This award was funded by the National Institute of Health and Care Research (NIHR) Health and Social Care Delivery Research programme (NIHR award ref: 17/99/19) and is published in full in Health and Social Care Delivery Research; Vol. 12, No. 11. See the NIHR Funding and Awards website for further award information.


The Family Nurse Partnership is an intensive home visiting service that offers first-time young mothers up to 64 visits with a family nurse from pregnancy to their child's second birthday. The Family Nurse Partnership aims to improve birth outcomes, child health and development and promote economic self-sufficiency among young mothers. Previous research in England found no differences in birthweight, maternal smoking, repeat pregnancies or accident and emergency attendances between mothers who did or did not take part in the Family Nurse Partnership. However, children in the Family Nurse Partnership group had better measures of development at school age. We aimed to add to the evidence from earlier studies, by using electronic records that are routinely collected as part of health, education and social care services, to compare outcomes for around 26,000 mothers enrolled in the Family Nurse Partnership between 2010 and 2019 with similar mothers who were not enrolled. This study showed that around one in four mothers who were eligible for the programme were enrolled in the Family Nurse Partnership, and family nurses gave priority to mothers who were younger, more deprived or who had other markers of vulnerability (e.g. a history of substance misuse violence, self-harm or mental health conditions). We found no evidence of a difference in indicators of child maltreatment between mothers who were enrolled in the Family Nurse Partnership and those who were not enrolled, but we found weak evidence to suggest that children born to mothers enrolled in the Family Nurse Partnership were more likely to achieve a Good Level of Development at school entry (age 5). We also saw that mothers enrolled in the Family Nurse Partnership were less likely than those who were not enrolled to have their next child within 18 months of their first child. More research is needed to understand which elements of intensive home visiting services work best, for whom and when. This will help inform decisions about whether it is better to offer highly intensive services for a small portion of the target population or to extend and enhance existing universal health visiting services to better support all adolescent mothers.

RESUMEN

INTRODUCTION: Maternal social disadvantage adversely affects maternal and offspring health, with limited research on placental outcomes. Therefore, we examined maternal sociodemographic factor associations with placental and birth outcomes in general (Lifeways Cross-Generation Cohort) and at-risk (PEARS Study of mothers with overweight or obesity) populations of pregnant women. METHODS: TwoStep cluster analysis profiled Lifeways mothers (n = 250) based on their age, parity, marital status, household income, private healthcare insurance, homeowner status, and education. Differences in placental and birth outcomes (untrimmed placental weight (PW), birthweight (BW) and BW:PW ratio) between clusters were assessed using one-way ANOVA and chi-square tests. Partial least squares regression analysed individual effects of sociodemographic factors on placental and birth outcomes in Lifeways and PEARS mothers (n = 461). RESULTS: Clusters were classified as "Married Homeowners" (n = 140, 56 %), "Highest Income" (n = 58, 23.2 %) and "Renters" (n = 52, 20.8 %) in the Lifeways Cohort. Renters were younger, more likely to smoke, have a means-tested medical card and more pro-inflammatory diets compared to other clusters (p < 0.01). Compared to Married Homeowners, renters' offspring had lower BW (-259.26 g, p < 0.01), shorter birth length (-1.31 cm, p < 0.01) and smaller head circumference (-0.59 cm, p = 0.02). PLS regression analyses identified nulliparity as having the greatest negative effect on PW (Lifeways and PEARS) while being a homeowner had the greatest positive effect on PW (Lifeways). CONCLUSION: Certain combinations of sociodemographic factors (particularly homeownership) were associated with less favourable lifestyle factors, and with birth, but not placental outcomes. When explored individually, parity contributed to the prediction of placental and birth outcomes in both cohorts of pregnant women.

RESUMEN

Background: Mental disorders are a growing public health concern and evidence has linked chronic low-grade inflammation with depression and well-being. Research also suggests that certain modifiable lifestyle factors such as smoking, alcohol use, physical activity, diet quality and BMI are related to psychological health. These may modulate the relationship between low-grade inflammation and mental health conditions. In this study we examined inflammatory biomarker associations with two psychological health scores and investigated whether relationships are influenced by lifestyle factors and BMI. Methods: This was a cross-sectional study of 1824 middle-to older-aged men and women randomly selected from a large primary care centre. Depressive symptoms and well-being were assessed using the 20-item Centre for Epidemiologic Studies Depression (CES-D) Scale and the World Health Organization-Five (WHO-5) Well-Being Index. Linear regression analyses were performed to examine depression and well-being score relationships with six inflammatory biomarkers, and a composite inflammatory biomarker score, adjusting for demographic characteristics, health conditions, lifestyle factors and BMI. Results: Depression and well-being score associations with complement component 3 (CES-D only) c-reactive protein, interleukin 6, leptin, white blood cell counts, neutrophils and the inflammatory biomarker score were observed. These relationships survived adjustment for demographic variables and health conditions but were attenuated in models which included lifestyle factors and BMI. In final models, only leptin (ß = 0.566, p = 0.018) and inflammatory score (ß = 0.137, p = 0.004) associations with the CES-D score remained. Conclusions: These findings suggest that the relationship between systemic low-grade inflammation and depressive symptoms and well-being may be largely explained by lifestyle factors and adiposity, highlighting the potential importance of promoting a healthy lifestyle in the treatment of depressive disorders.

RESUMEN

BACKGROUND: Maternal healthy lifestyle behaviors during pregnancy have been associated with reduced risk of offspring overweight and obesity (OWOB). However, there has been little investigation, in the context of the Paternal Origins of Health and Disease (POHaD) paradigm, of the potential influence of the paternal lifestyle on offspring OWOB. OBJECTIVES: To describe paternal healthy lifestyle factors around pregnancy and investigate their associations, individually and combined, with offspring risk of OWOB during childhood. MATERIALS AND METHODS: Participants included 295 father-child pairs from the Lifeways Cross-Generation Cohort Study. A composite paternal healthy lifestyle score (HLS) based on having a high dietary quality (top 40% of the Healthy Eating Index-2015), meeting physical activity guidelines (≥450 MET-min/week of moderate-to-vigorous physical activity), having a healthy body mass index (BMI) (18.5-24.9 kg/m2 ), being a non-smoker, and having no/moderate alcohol intake, was calculated (range 0-5). Paternal HLS (and individual components) associations with child BMI and waist-to-height ratio (WHtR) at age 5 and 9 years were assessed using linear (BMI z-scores and WHtR) and logistic (IOTF categories) regression analyses, adjusted for sociodemographic characteristics. RESULTS: At age 5 and 9 years, 23.5% and 16.9% of children were classified as living with OWOB, respectively. Of the 160 pairs with a complete HLS, 45.0% of the fathers had unfavorable lifestyle factors, determined by a low HLS between 0 and 2 points. Although a low paternal HLS was not significantly associated with a higher risk of childhood OWOB measured using either BMI z-scores and IOTF categories, it was associated with a greater child WHtR, an indicator of central adiposity, at 9 years of age (ß [95% CI] = 0.04 [0.01,0.07]). DISCUSSION AND CONCLUSION: Almost half of the fathers had unfavorable lifestyle factors around pregnancy. A low paternal HLS was associated with a greater child WHtR at 9 years but not with a higher risk of childhood OWOB when measured by BMI z-scores or IOTF categories.

RESUMEN

Quantum dots are promising candidates for telecom single photon sources due to their tunable emission across the different low-loss telecommunications bands, making them compatible with existing fiber networks. Their suitability for integration into photonic structures allows for enhanced brightness through the Purcell effect, supporting efficient quantum communication technologies. Our work focuses on InAs/InP QDs created via droplet epitaxy MOVPE to operate within the telecoms C-band. We observe a short radiative lifetime of 340 ps, arising from a Purcell factor of 5, owing to integration of the QD within a low-mode-volume photonic crystal cavity. Through in-situ control of the sample temperature, we show both temperature tuning of the QD's emission wavelength and a preserved single photon emission purity at temperatures up to 25K. These findings suggest the viability of QD-based, cryogen-free C-band single photon sources, supporting applicability in quantum communication technologies.

RESUMEN

Background: Exposure to adverse childhood experiences (ACEs) has been linked with increased cardiometabolic risk in adulthood. Low-grade systemic inflammation may underlie this association. Thus far, however, there has been limited investigation of later life inflammatory biomarkers in the context of childhood adversity. Objectives: To assess ACE history, and ACE subcategory, relationships with a broad range of inflammatory biomarkers in middle-to older-aged adults to test the hypothesis that ACE exposure is associated with an unfavourable inflammatory profile in adulthood and determine whether associations vary by ACE subtype and sex. Methods: This study used data from a random sample of 1,839 men and women aged 46-74 years. Participant exposure to ACEs (overall and subtypes including abuse, neglect and household dysfunction) was determined using a validated 10-item ACE questionnaire. Inflammatory biomarkers (pro-inflammatory cytokines, adipocytokines, acute-phase response proteins, white blood cell counts and their constituents, coagulation factors and glycoprotein acetyl) were measured from participant blood samples. Linear regression analyses examined relationships between ACE history (overall and each subcategory) and inflammatory biomarkers in adulthood, controlling for potential confounders. Sex-stratified and mediation analyses were also conducted. Results: In age and sex-adjusted models, ACE history was significantly associated with higher c-reactive protein (p = 0.027), resistin (p = 0.024), white blood cell count (WBC) (p = 0.034), monocyte (p = 0.044), eosinophil (p = 0.031) and plasminogen activator inhibitor-1 (p = 0.047) concentrations, and lower adiponectin (p = 0.025) levels. Results from stratified analyses indicated sex differences and ACE subtype specific associations, with household dysfunction identified as the main driver of positive ACE associations with WBCs and constituents (all p < 0.05). Mediation analyses suggested that BMI and smoking mediate relationships between ACE exposures and increased inflammation. Conclusions: This study provides evidence that ACE exposure may be associated with more pro-inflammatory and pro-thrombotic profiles in adulthood. Associations differed according to ACE subtype, and sex differences exist, which may influence cardiometabolic risk.

RESUMEN

BACKGROUND: Evidence has linked low-grade systemic inflammation and visceral adipose tissue (VAT) with development of chronic conditions. Cytokines and select proteins released by VAT may promote a low-grade inflammatory response. A number of equations have been developed to estimate VAT levels. In this study, we compared predicted VAT equation relationships with biomarkers of inflammation. METHODS: This was a cross-sectional study of 2038 men and women aged 46-73 years. Correlation and linear regression analyses were performed to examine inflammatory biomarker relationships with four commonly assessed anthropometric measures and 10 predicted VAT equations. RESULTS: Compared with anthropometric measures, predicted VAT equations were found to explain a greater proportion of variance in CRP (R2 = .075, p = .001), IL-6 (R2 = .060, p = .001), TNF-α (R2 = .017, p = .005), resistin (R2 = .011, p = .012), monocyte (R2 = .027, p = .001), eosinophil (R2 = .012, p = .01) and basophil (R2 = .015, p = .002) levels in males, and a greater variance in concentrations of C3 (R2 = .175, p = .001), IL-6 (R2 = .090, p = .001), TNF-α (R2 = .036, p = .001), adiponectin (R2 = .121, p = .001), the adiponectin-to-leptin ratio (R2 = .444, p = .001), resistin (R2 = .025, p = .001), white blood cell count (R2 = .057, p = .001), neutrophils (R2 = .061, p = .001) and lymphocytes (R2 = .020, p = .001) in females. CONCLUSION: Equations for assessing VAT levels might be useful to characterise metabolic health. Further studies that examine predicted VAT relationships with disease and mortality outcomes are warranted.

RESUMEN

BACKGROUND: Research is the scientific basis for the profession of dietetics, as it must be located and applied in evidence-based practice (EBP). EBP is often presented as a foundational skill for research. CEAR - Core, Evidence Application, Research - is a newly proposed model that separates Research and Evidence Application skills into distinct domains, jointly supported by a set of Core skills, thus acknowledging that education and advancement in one domain neither requires nor precipitates education and advancement in the other. The goal was to investigate the content and construct validity of the new CEAR Model. METHODS: A cross-sectional online survey of randomly selected dietitians in the United States was used to collect CEAR domain scores, validated measures of research or EBP skills and self-reported characteristics. Exploratory factor analysis, Cronbach's α and Pearson correlation between various tools and CEAR domains were used to assess validity and reliability. Analysis of variance (ANOVA) and multiple linear regression between CEAR domains and participant characteristics were used to assess convergent and divergent validity. RESULTS: One hundred and fifty-four responses with a valid CEAR score were received and led to a three-factor solution, supporting the theorised differentiation of research from evidence application skills (content validity). Internal reliability for the CEAR Model overall and for each domain was high. The hypothesised correlations between existing research or EBP measurement tools and the relevant CEAR domains were found (construct validity). Known groups analysis demonstrated the expected differences in CEAR domain scores based on participant characteristics. CONCLUSIONS: The CEAR Model demonstrates preliminary validity and internal reliability. It adds to the current literature by acknowledging the separateness of evidence application skills from research skills.

RESUMEN

BACKGROUND: Macrosomia (birthweight ≥ 4 kg or ≥ 4.5 kg) is strongly associated with a predisposition to childhood obesity, which in turn is linked with adverse cardiometabolic health. Despite this, there is a lack of longitudinal investigation on the impact of high birthweight on cardiometabolic outcomes in youth. The preteen period represents an important window of opportunity to further explore this link, to potentially prevent cardiometabolic profiles worsening during puberty. METHODS: This is a secondary analysis of 9-11-year-olds (n = 405) born to mothers in the ROLO longitudinal birth cohort study, who previously delivered an infant with macrosomia. Preteens were dichotomised into those born with and without macrosomia, using two common cut-off criteria (birthweight ≥ 4 kg (n = 208) and < 4 kg; ≥ 4.5 kg (n = 65) and < 4.5 kg). Cardiometabolic health was assessed using anthropometry, dual-energy x-ray absorptiometry, blood pressure, heart rate, cardiorespiratory endurance (20-m shuttle run test), and non-fasting serum biomarkers for a subgroup (n = 213). Statistical comparisons between the two groups were explored using independent t-tests, Mann-Whitney U tests, and Chi-square tests. Crude and adjusted linear regression models investigated associations between macrosomia and preteen cardiometabolic outcomes. RESULTS: In total, 29.3% (n = 119) of preteens had overweight/obesity based on their BMI z-score. Preteens born ≥ 4 kg had lower median (IQR) C3 concentrations (1.38 (1.22, 1.52) g/L vs. 1.4 (1.26, 1.6) g/L, p = 0.043) and lower median (IQR) ICAM-1 concentrations (345.39 (290.34, 394.91) ng/mL vs. 387.44 (312.91, 441.83) ng/mL, p = 0.040), than those born < 4 kg. Those born ≥ 4.5 kg had higher mean (SD) BMI z-scores (0.71 (0.99) vs. 0.36 (1.09), p = 0.016), and higher median (IQR) lean mass (24.76 (23.28, 28.51) kg vs. 23.87 (21.9, 26.79) kg, p = 0.021), than those born < 4.5 kg. Adjusted linear regression analyses revealed birthweight ≥ 4 kg was negatively associated with C3 concentration (g/L) (B = - 0.095, 95% CI = - 0.162, - 0.029, p = 0.005) and birthweight ≥ 4.5 kg was positively associated with weight z-score (B = 0.325, 95% CI = 0.018, 0.633, p = 0.038), height z-score (B = 0.391, 95% CI = 0.079, 0.703, p = 0.014), lean mass (kg) (B = 1.353, 95% CI = 0.264, 2.442, p = 0.015) and cardiorespiratory endurance (B = 0.407, 95% CI = 0.006, 0.808, p = 0.047). CONCLUSION: This study found no strong evidence to suggest that macrosomia is associated with adverse preteen cardiometabolic health. Macrosomia alone may not be a long-term cardiometabolic risk factor. Trial registration ISRCTN54392969 registered at  www.isrctn.com .

RESUMEN

PURPOSE: There is increasing interest in the health benefits of plant-based diets (PBDs). Evidence reports favourable associations with inflammatory profiles and reduced cardiovascular disease risk. However, limited studies have examined relationships between PBD indices (PDIs) and inflammatory biomarkers. We explored overall PDI, healthful PDI (hPDI) and unhealthful PDI (uPDI) associations with inflammatory biomarker profiles. METHODS: This cross-sectional analysis included 1986 middle- to older-aged adults from the Mitchelstown Cohort. PDI scores were calculated using validated food frequency questionnaires. PDI score associations with inflammatory biomarkers were assessed via linear regression analysis, with adjustment for potential confounders. RESULTS: Comparison of quintiles (Q5 vs Q1) revealed lower concentrations of C-reactive protein (CRP), interleukin 6 (IL-6), white blood cells (WBCs), neutrophils and monocytes, and the leptin-to-adiponectin ratio (PDI and hPDI P < 0.05); lower leptin (PDI, P < 0.05), and complement component 3 (C3), tumour necrosis factor alpha (TNF-α), plasminogen activator inhibitor 1, lymphocytes and eosinophils (hPDI, P < 0.05); and higher concentrations of adiponectin (PDI and hPDI, P < 0.05). Conversely, higher concentrations of C3, CRP, IL-6, TNF-α, resistin, WBCs, neutrophils, lymphocytes, monocytes and eosinophils, and the neutrophil-to-lymphocyte ratio, and lower adiponectin concentrations were observed comparing uPDI quintiles (P < 0.05). In fully adjusted regression models, higher hPDI scores were associated with lower concentrations of C3, TNF-α, WBCs, neutrophils and monocytes (all P < 0.01). Higher uPDI scores were associated with higher C3 and TNF-α concentrations (all P < 0.01). CONCLUSION: This study provides evidence that a more healthful PBD is associated with a more favourable inflammatory profile and that a more unhealthful PBD is associated with the reverse.

RESUMEN

First published in 2019, the Ovarian-Adnexal Reporting and Data System (O-RADS) US provides a standardized lexicon for ovarian and adnexal lesions, enables stratification of these lesions with use of a numeric score based on morphologic features to indicate the risk of malignancy, and offers management guidance. This risk stratification system has subsequently been validated in retrospective studies and has yielded good interreader concordance, even with users of different levels of expertise. As use of the system increased, it was recognized that an update was needed to address certain clinical challenges, clarify recommendations, and incorporate emerging data from validation studies. Additional morphologic features that favor benignity, such as the bilocular feature for cysts without solid components and shadowing for solid lesions with smooth contours, were added to O-RADS US for optimal risk-appropriate scoring. As O-RADS US 4 has been shown to be an appropriate cutoff for malignancy, it is now recommended that lower-risk O-RADS US 3 lesions be followed with US if not excised. For solid lesions and cystic lesions with solid components, further characterization with MRI is now emphasized as a supplemental evaluation method, as MRI may provide higher specificity. This statement summarizes the updates to the governing concepts, lexicon terminology and assessment categories, and management recommendations found in the 2022 version of O-RADS US.
