RESUMEN

Biochar is amongst a growing suite of approaches developed to address the climate crisis by removing carbon dioxide from the atmosphere; yet public awareness of biochar is low. In this situation, mass-media reporting plays an important role in making an issue public and in creating expectations about its risks and benefits. In British broadsheet newspapers, a promissory, future-oriented discourse on biochar has emerged that is rhetorically configured through, for example, evaluative adjectives, verbs, hyperbole, and allusions to literary and cultural symbols that confer a sense of mystique. Biochar is promoted as an almost magical fix, based on its ability to soak up and store carbon, improve soil health, increase crops yields, and reduce pollutants. Conversely, some of the possible negative aspects of biochar are couched in the form of sarcasm and parody, while others are made invisible. This sets biochar up as a moral good that the public ought to accept, rather than opening up a public debate about its risks and benefits. Engaging in a fine-grained rhetorical analysis of the way promises about biochar are constructed expands the methodological and empirical repertoire of the sociology of expectations and, in future, can be applied to the analysis of other emerging climate change technologies, especially those relating to carbon removal.

RESUMEN

PURPOSE: Long COVID-19 syndrome occurs in 10-20 % of people after a confirmed/probable SARS-COV-2 infection; new symptoms begin within three months of COVID-19 diagnosis and last > 8 weeks. Little is known about risk factors for long COVID, particularly in older people who are at greater risk of COVID complications. METHODS: Data are from Women's Health Initiative (WHI) postmenopausal women who completed COVID surveys that included questions on whether they had ever been diagnosed with COVID and length and nature of symptoms. Long COVID was classified using standard consensus criteria. Using WHI demographic and health data collected at study enrollment (1993-98) through the present day, machine learning identified the top 20 risk factors for long COVID. These variables were tested in logistic regression models. RESULTS: Of n = 37,280 survey respondents, 1237 (mean age = 83 years) reported a positive COVID-19 test and 425 (30 %) reported long COVID. Symptoms included an array of neurological, cardio-pulmonary, musculoskeletal, and general fatigue, and malaise symptoms. Long COVID risk factors included weight loss, physical and mobility limitations, and specific heath conditions (e.g., history of heart valve procedure, rheumatoid arthritis). CONCLUSIONS: Knowledge of risk factors for long COVID may be the first step in understanding the etiology of this complex disease.

RESUMEN

PURPOSE: Menopausal hormone therapy's influence on ovarian and endometrial cancers remains unsettled. Therefore, we assessed the long-term influence of conjugated equine estrogen (CEE) plus medroxyprogesterone acetate (MPA) and CEE-alone on ovarian and endometrial cancer incidence and mortality in the Women's Health Initiative randomized, placebo-controlled clinical trials. MATERIALS AND METHODS: Postmenopausal women, age 50-79 years, were entered on two randomized clinical trials evaluating different menopausal hormone therapy regimens. In 16,608 women with a uterus, 8,506 were randomly assigned to once daily 0.625 mg of CEE plus 2.5 mg once daily of MPA and 8,102 placebo. In 10,739 women with previous hysterectomy, 5,310 were randomly assigned to once daily 0.625 mg of CEE-alone and 5,429 placebo. Intervention was stopped for cause before planned 8.5-year intervention after 5.6 years (CEE plus MPA) and after 7.2 years (CEE-alone). Outcomes include incidence and mortality from ovarian and endometrial cancers and deaths after these cancers. RESULTS: After 20-year follow-up, CEE-alone, versus placebo, significantly increased ovarian cancer incidence (35 cases [0.041%] v 17 [0.020%]; hazard ratio [HR], 2.04 [95% CI, 1.14 to 3.65]; P = .014) and ovarian cancer mortality (P = .006). By contrast, CEE plus MPA, versus placebo, did not increase ovarian cancer incidence (75 cases [0.051%] v 63 [0.045%]; HR, 1.14 [95% CI, 0.82 to 1.59]; P = .44) or ovarian cancer mortality but did significantly lower endometrial cancer incidence (106 cases [0.073%] v 140 [0.10%]; HR, 0.72 [95% CI, 0.56 to 0.92]; P = .01). CONCLUSION: In randomized clinical trials, CEE-alone increased ovarian cancer incidence and ovarian cancer mortality, while CEE plus MPA did not. By contrast, CEE plus MPA significantly reduced endometrial cancer incidence.

RESUMEN

BACKGROUND: Tea and coffee are the most frequently consumed beverages in the world. Green tea in particular contains compounds with potential anti-cancer effects, but its association with survival after ovarian cancer is uncertain. METHODS: We investigated the associations between tea and coffee consumption before diagnosis and survival using data from 10 studies in the Ovarian Cancer Association Consortium. Data on tea (green, black, herbal), coffee and caffeine intake were available for up to 5724 women. We used Cox proportional hazards regression to estimate adjusted hazard ratios (aHR) and 95% confidence intervals (CI). RESULTS: Compared with women who did not drink any green tea, consumption of one or more cups/day was associated with better overall survival (aHR = 0.84, 95% CI 0.71-1.00, p-trend = 0.04). A similar association was seen for ovarian cancer-specific survival in five studies with this information (aHR = 0.81, 0.66-0.99, p-trend = 0.045). There was no consistent variation between subgroups defined by clinical or lifestyle characteristics and adjustment for other aspects of lifestyle did not appreciably alter the estimates. We found no evidence of an association between coffee, black or herbal tea, or caffeine intake and survival. CONCLUSION: The observed association with green tea consumption before diagnosis raises the possibility that consumption after diagnosis might improve patient outcomes.

RESUMEN

PURPOSE: The purpose of this study was to evaluate RB1 expression and survival across ovarian carcinoma histotypes and how co-occurrence of BRCA1 or BRCA2 (BRCA) alterations and RB1 loss influences survival in tubo-ovarian high-grade serous carcinoma (HGSC). EXPERIMENTAL DESIGN: RB1 protein expression was classified by immunohistochemistry in ovarian carcinomas of 7,436 patients from the Ovarian Tumor Tissue Analysis consortium. We examined RB1 expression and germline BRCA status in a subset of 1,134 HGSC, and related genotype to overall survival (OS), tumor-infiltrating CD8+ lymphocytes, and transcriptomic subtypes. Using CRISPR-Cas9, we deleted RB1 in HGSC cells with and without BRCA1 alterations to model co-loss with treatment response. We performed whole-genome and transcriptome data analyses on 126 patients with primary HGSC to characterize tumors with concurrent BRCA deficiency and RB1 loss. RESULTS: RB1 loss was associated with longer OS in HGSC but with poorer prognosis in endometrioid ovarian carcinoma. Patients with HGSC harboring both RB1 loss and pathogenic germline BRCA variants had superior OS compared with patients with either alteration alone, and their median OS was three times longer than those without pathogenic BRCA variants and retained RB1 expression (9.3 vs. 3.1 years). Enhanced sensitivity to cisplatin and paclitaxel was seen in BRCA1-altered cells with RB1 knockout. Combined RB1 loss and BRCA deficiency correlated with transcriptional markers of enhanced IFN response, cell-cycle deregulation, and reduced epithelial-mesenchymal transition. CD8+ lymphocytes were most prevalent in BRCA-deficient HGSC with co-loss of RB1. CONCLUSIONS: Co-occurrence of RB1 loss and BRCA deficiency was associated with exceptionally long survival in patients with HGSC, potentially due to better treatment response and immune stimulation.

RESUMEN

BACKGROUND: Although endometriosis is a common condition-affecting ∼10% of premenopausal individuals-its etiology is unknown. Diet receives a lot of attention from patients, but studies of the role of diet are limited. Examining dietary patterns is essential to provide new insight. OBJECTIVE: We sought to determine whether dietary patterns are associated with laparoscopically-confirmed endometriosis diagnosis. STUDY DESIGN: We conducted a prospective cohort study among 81,997 premenopausal participants of the Nurses' Health Study II, who were followed from 1991-2015. Diet was assessed with validated food frequency questionnaires every 4 years. We examined 6 dietary patterns: Western, Prudent, Alternative Healthy Eating Index, Dietary Approaches to Stop Hypertension, an estrogen-associated pattern, and a proinflammatory pattern. Cox proportional hazard ratios and 95% confidence intervals were used to quantify the association between each of these patterns and laparoscopically-confirmed endometriosis diagnosis. RESULTS: Three thousand eight hundred ten incident cases of endometriosis were diagnosed during 24 years of follow-up. Adherence to the Alternative Healthy Eating Index, reflecting a healthier dietary pattern, was associated with a 13% lower risk of endometriosis diagnosis (fifth vs first quintile 95% confidence interval, 0.78-0.96; Ptrend=.02). Participants in the highest quintile of the Western dietary pattern, characterized by high intake of red meat, processed meat, refined grains, and desserts, had a 27% higher risk of endometriosis diagnosis than those in the lowest quintile (95% confidence interval, 1.09-1.47; Ptrend=.004). The Prudent, Dietary Approaches to Stop Hypertension, and estrogen-associated dietary patterns did not demonstrate clear associations with endometriosis risk, and there was the suggestion of a higher risk of endometriosis diagnosis among those with a higher proinflammatory diet score (hazard ratio for fifth vs first quintile, 1.10 [95% confidence interval, 0.99-1.23]; Ptrend=.01). CONCLUSION: Our results suggest that consuming a dietary pattern that adheres to the Alternative Healthy Eating Index-2010 recommendations lowers the risk of endometriosis diagnosis, potentially through a beneficial impact on pelvic pain. In addition, consuming a less healthy diet high in red/processed meats and refined grains may have a detrimental impact on endometriosis symptoms.

RESUMEN

BACKGROUND: There has been limited prior research on the association between infertility and risk of colorectal cancer. METHODS: Data from postmenopausal women in the Women's Health Initiative were used to estimate the association between self-reported infertility (12 months of trying to get pregnant without achieving a pregnancy) and the risk of colorectal cancer using Cox proportional hazard models. RESULTS: No association was observed between infertility and risk of postmenopausal colorectal cancer [RR, 0.97; 95% confidence interval (CI), 0.87-1.08], invasive colorectal cancer (RR, 0.99; 95% CI, 0.88-1.10), or colorectal cancer mortality (RR, 0.89; 95% CI, 0.71-1.12). CONCLUSIONS: Infertility was not found to be associated with colorectal cancer risk among postmenopausal women. Risk did not vary by specific infertility diagnoses. IMPACT: Infertility may not be associated with colorectal cancer risk.

RESUMEN

Limited estimates exist on risk factors for epithelial ovarian cancer (EOC) in Asian, Hispanic, and Native Hawaiian/Pacific Islander women. Participants in this study included 1734 Asian (n = 785 case and 949 control participants), 266 Native Hawaiian/Pacific Islander (n = 99 case and 167 control participants), 1149 Hispanic (n = 505 case and 644 control participants), and 24 189 White (n = 9981 case and 14 208 control participants) from 11 studies in the Ovarian Cancer Association Consortium. Logistic regression models estimated odds ratios (ORs) and 95% CIs for risk associations by race and ethnicity. Heterogeneity in EOC risk associations by race and ethnicity (P ≤ .02) was observed for oral contraceptive (OC) use, parity, tubal ligation, and smoking. We observed inverse associations with EOC risk for OC use and parity across all groups; associations were strongest in Native Hawaiian/Pacific Islander and Asian women. The inverse association for tubal ligation with risk was most pronounced for Native Hawaiian/Pacific Islander participants (odds ratio (OR) = 0.25; 95% CI, 0.13-0.48) compared with Asian and White participants (OR = 0.68 [95% CI, 0.51-0.90] and OR = 0.78 [95% CI, 0.73-0.85], respectively). Differences in EOC risk factor associations were observed across racial and ethnic groups, which could be due, in part, to varying prevalence of EOC histotypes. Inclusion of greater diversity in future studies is essential to inform prevention strategies. This article is part of a Special Collection on Gynecological Cancers.

RESUMEN

PURPOSE: This study seeks to examine the relationship between anxiety-symptom severity and sleep behaviors in autistic children receiving cognitive behavioral therapy (CBT). METHODS: We conducted a secondary-data analysis from a sample of 93 autistic youth, 4 to 14 years, participating in 24 weeks of CBT. Clinicians completed the Pediatric Anxiety Rating Scale (PARS) and parents completed the Children's Sleep Habits Questionnaire, Abbreviated/Short Form (CSHQ-SF) at baseline, mid-treatment, post-treatment and 3 months post-treatment. Mediation analysis evaluated the role of anxiety symptoms in mediating the effect of time in treatment on sleep. RESULTS: There was a negative association between time in treatment and scores on the CSHQ-SF (b = - 3.23, SE = 0.493, t = - 6.553, p < 0.001). Increased time in treatment was associated with decreased anxiety (b = - 4.66, SE = 0.405, t = - 11.507, p < 0.001), and anxiety symptoms decreased with CSHQ-SF scores (b = 0.322, SE = 0.112, t = 2.869, p = 0.005). The indirect effect of time in treatment on CSHQ-SF scores through PARS reduction was negative, but not statistically significant. CONCLUSION: Increased time in CBT was associated with decreased anxiety severity and improved sleep behaviors. Reductions in anxiety symptoms may mediate improvements in sleep problems, but larger sample sizes are necessary to explore this further.

RESUMEN

Over the last decade, there have been repeated calls to expand the operationalisation of food parenting practices. The conceptualisation and measurement of these practices has been based primarily on research with parent-child dyads. One unexplored dimension of food parenting pertains to the evaluation of practices specific to feeding siblings. This study describes the development and validation of the Feeding Siblings Questionnaire (FSQ) - a tool designed to measure practices in which siblings are positioned as mediators in parents' attempts to prompt or persuade a child to eat. Item development was guided by a conceptual model derived from mixed-methods research and refined through expert reviews and cognitive interviews. These interviews were conducted in two phases, where parents responded to the questionnaire primarily to test i) the readability and relevance of each item, and ii) its overall feasibility. The instrument was completed by 330 parents (96.1% mothers) in Australia with two children aged 2-5 years, and repeated by 133 parents (40.3%) two weeks later. Exploratory factor analysis was performed on baseline data. Internal consistency and test re-test reliability of the subsequent subscales were examined. Construct validity was assessed through comparisons with existing measures of food parenting practices and child eating behaviours. The final FSQ scale included 22 items, reflecting five food parenting practices: sibling competitiveness, active sibling influence, threatening unequal division of food, sibling role modelling, and vicarious operant conditioning. Internal consistency and test re-test reliability estimates were high, and there was some evidence of convergent construct validity. While its factor structure should be confirmed in a different sample, the FSQ offers a novel tool for assessing, monitoring, and evaluating feeding interactions beyond those confined to the parent-child dyad.

RESUMEN

BACKGROUND: In the context of mental health research, co-production involves people with lived expertise, those with professional or academic expertise, and people with both of these perspectives collaborating to design and actualize research initiatives. In the literature, two dominant perspectives on co-production emerge. The first is in support of co-production, pointing to the transformative value of co-production for those involved, the quality of services developed through this process, as well as to broader system-level impacts (e.g. influencing changes in health system decision making, care practices, government policies, etc.). The second stance expresses scepticism about the capacity of co-production to engender genuine collaboration given the deeply ingrained power imbalances in the systems in which we operate. While some scholars have explored the intersections of these two perspectives, this body of literature remains limited. MAIN TEXT: This paper contributes to the literature base by exploring the nuances of co-production in health research. Using our mental health participatory action research project as a case example, we explore the nuances of co-production through four key values that we embraced: 1. Navigating power relations together 2. Multi-directional learning 3. Slow and steady wins the race 4. Connecting through vulnerability CONCLUSIONS: By sharing these values and associated principles and practices, we invite readers to consider the complexities of co-production and explore how our experiences may inform their practice of co-production. Despite the inherent complexity of co-production, we contend that pursuing authentic and equitable collaborations is integral to shaping a more just and inclusive future in mental health research and the mental health system at large.


BACKGROUND: In the context of mental health research, co-production is a process where people with lived experiences, those with academic or professional experience, and people with both of these perspectives collaborate to design and actualize research initiatives. In the literature, there are two main opinions about co-production. The first opinion is that co-production is beneficial for those involved, improves the quality of services, and can also have impacts at higher system levels (e.g. influencing changes in health system decision making, care practices, government policies, etc.). The second opinion is doubtful that co-production has the ability to foster authentic collaboration because of the differences in power between academic and health systems. Even though some scholars have looked at both opinions, there is not a lot of research on this. MAIN TEXT: This paper contributes to the literature base exploring the nuances of co-production in health research. Using our mental health participatory action research project as a case example, we explore the nuances of co-production through four key values that we embraced: 1. Navigating power relations together 2. Multi-directional learning 3. Slow and steady wins the race 4. Connecting through vulnerability CONCLUSIONS: By sharing these values and associated principles and practices, we invite readers to consider the complexities of co-production and explore how our process may inform their engagement with co-production. We argue that pursuing authentic collaborations is key to shaping a more just and inclusive future in mental health research and the mental health system at large.

RESUMEN

PURPOSE: Although infertility (i.e., failure to conceive after ≥ 12 months of trying) is strongly correlated with established breast cancer risk factors (e.g., nulliparity, number of pregnancies, and age at first pregnancy), its association with breast cancer incidence is not fully understood. Previous studies were primarily small clinic-based or registry studies with short follow-up and predominantly focused on premenopausal breast cancer. The objective of this study was to assess the relationship between infertility and postmenopausal breast cancer risk among participants in the Women's Health Initiative (analytic sample = 131,784; > 25 years of follow-up). METHODS: At study entry, participants were asked about their pregnancy history, infertility history, and diagnosed reasons for infertility. Incident breast cancers were self-reported with adjudication by trained physicians reviewing medical records. Cox proportional hazards models were used to estimate risk of incident postmenopausal breast cancer for women with infertility (overall and specific infertility diagnoses) compared to parous women with no history of infertility. We examined mediation of these associations by parity, age at first term pregnancy, postmenopausal hormone therapy use at baseline, age at menopause, breastfeeding, and oophorectomy. RESULTS: We observed a modest association between infertility (n = 23,406) and risk of postmenopausal breast cancer (HR = 1.07; 95% CI 1.02-1.13). The association was largely mediated by age at first term pregnancy (natural indirect effect: 46.4% mediated, CI 12.2-84.3%). CONCLUSION: These findings suggest that infertility may be modestly associated with future risk of postmenopausal breast cancer due to age at first pregnancy and highlight the importance of incorporating reproductive history across the life course into breast cancer analyses.

RESUMEN

OBJECTIVE: Anti-Müllerian hormone is a reliable measure of ovarian reserve associated with menopause timing and fertility. Previous studies have observed that individuals with endometriosis have lower anti-Müllerian hormone levels than those without. However, sample sizes have been small and information is limited regarding the long-term influence of endometriosis on anti-Müllerian hormone levels among the general population, which may have important implications for menopause timing and chronic disease risk. METHODS: Among 1961 premenopausal women in the Nurses' Health Study II who provided a blood sample and had not been pregnant in the last 6 months, we used generalized linear models to determine the association between laparoscopically-confirmed endometriosis and log-transformed plasma anti-Müllerian hormone level, adjusted for age (continuous and squared) and other potential confounding variables. RESULTS: Participants were on average 40 years old (interquartile range 37-42 years) at blood draw. Women with endometriosis diagnosed prior to blood draw (n = 119) had a lower mean anti-Müllerian hormone level (1.6 ng/mL [SD = 2.3]) than women without known endometriosis (n = 1842) (2.8 ng/mL [SD = 3.0]). In multivariable adjusted models, women with endometriosis had 29.6 % lower anti-Müllerian hormone levels (95 % CI: -45.4, -9.2 %) than women without. This association was greater among women with a body mass index of 25 kg/m2 or more (percent difference: -44.0 % (-63.7, -13.8)), compared to those with a body mass index of under 25 kg/m2 (percent difference: -19.8 % (-41.7, 10.4)), but did not vary by parity or infertility history. CONCLUSIONS: Lower anti-Müllerian hormone levels in women with endometriosis may be one mechanism through which endometriosis influences risk of infertility, younger age at menopause, and cardiovascular disease.

RESUMEN

The methyl CpG-binding protein-2 (MECP2) gene is located on the Xq28 region. Loss of function mutations or increased copies of MECP2 result in Rett syndrome (RTT) and MECP2 duplication syndrome (MDS), respectively. Individuals with both disorders exhibit overlapping autism symptoms, yet few studies have dissected the differences between these gene dosage sensitive disorders. Further, research examining sensory processing patterns in persons with RTT and MDS is largely absent. Thus, the goal of this study was to analyze and compare sensory processing patterns in persons with RTT and MDS. Towards this goal, caregivers of 50 female individuals with RTT and 122 male individuals with MDS, between 1 and 46 years of age, completed a standardized measure of sensory processing, the Sensory Experiences Questionnaire. Patterns detected in both disorders were compared against each other and against normative values. We found sensory processing abnormalities for both hyper- and hypo-sensitivity in both groups. Interestingly, abnormalities in MDS were more pronounced compared with in RTT, particularly with items concerning hypersensitivity and sensory seeking, but not hyposensitivity. Individuals with MDS also exhibited greater sensory symptoms compared with RTT in the areas of tactile and vestibular sensory processing and for both social and nonsocial stimuli. This study provides a first description of sensory symptoms in individuals with RTT and individuals with MDS. Similar to other neurodevelopmental disorders, a variety of sensory processing abnormalities was found. These findings reveal a first insight into sensory processing abnormalities caused by a dosage sensitive gene and may ultimately help guide therapeutic approaches for these disorders.

RESUMEN

OBJECTIVE: Nonresponsive parental feeding practices are associated with poorer appetite self-regulation in children. It is unknown whether this relationship extends beyond childhood to be prospectively associated with the onset of eating disorder (ED) symptoms in adolescence. This exploratory study therefore investigated prospective associations between early childhood parental feeding practices and adolescent ED symptoms and disordered eating behaviors. METHODS: Data were from two population-based cohorts with harmonized measures: Generation R (Netherlands; n = 4900) and Gemini (UK; n = 2094). Parents self-reported their pressure to eat, restriction and instrumental feeding (i.e., using food as a reward) at child age 4-5 years. Adolescents self-reported their compensatory behaviors (e.g., fasting, purging), binge-eating symptoms, restrained eating, uncontrolled eating, and emotional eating at 12-14 years. Associations between feeding practices and ED symptoms were examined separately in each cohort using generalized linear models. RESULTS: In Gemini, pressure to eat in early childhood was associated with adolescents engaging in compensatory behaviors. In Generation R, parental restriction was associated with adolescents engaging in compensatory behaviors, restrained eating, uncontrolled eating, and emotional eating. Instrumental feeding was associated with uncontrolled eating and emotional eating in Generation R. DISCUSSION: Nonresponsive parental feeding practices were associated with a greater frequency of specific ED symptoms and disordered eating in adolescence, although effect sizes were small and findings were inconsistent between cohorts. Potentially, the cultural and developmental context in which child-parent feeding interactions occur is important for ED symptoms. Further replication studies are required to better understand parents' role in the development and maintenance of ED-related symptoms. PUBLIC SIGNIFICANCE: Prospective research examining how early childhood parental feeding practices might contribute to adolescent ED symptoms is limited. In two population-based cohorts, nonresponsive feeding practices (restriction, instrumental feeding, pressure to eat) predicted increased frequency of some ED symptoms and disordered eating behaviors in adolescence, although associations were small and further replication is required. Findings support the promotion of responsive feeding practices, which may benefit young children's developing relationship with food.

RESUMEN

BACKGROUND: Obesity and eating disorders commonly co-occur and might share common risk factors. Appetite avidity is an established neurobehavioural risk factor for obesity from early life, but the role of appetite in eating disorder susceptibility is unclear. We aimed to examine longitudinal associations between appetitive traits in early childhood and eating disorder symptoms in adolescence. METHODS: In this longitudinal cohort study, we used data from Generation R (based in Rotterdam, the Netherlands) and Gemini (based in England and Wales). Appetitive traits at age 4-5 years were measured using the parent-reported Child Eating Behaviour Questionnaire. At age 12-14 years, adolescents self-reported on overeating eating disorder symptoms (binge eating symptoms, uncontrolled eating, and emotional eating) and restrictive eating disorder symptoms (compensatory behaviours and restrained eating). Missing data on covariates were imputed using Multivariate Imputation via Chained Equations. Ordinal and binary logistic regressions were performed in each cohort separately and adjusted for confounders. Pooled results were obtained by meta-analyses. Sensitivity analyses were performed on complete cases using inverse probability weighting. FINDINGS: The final study sample included 2801 participants from Generation R and 869 participants from Gemini. Pooled findings after meta-analyses showed that higher food responsiveness in early childhood increased the odds of binge eating symptoms (odds ratio [OR]pooled 1·47, 95% CI 1·26-1·72), uncontrolled eating (1·33, 1·21-1·46), emotional eating (1·26, 1·13-1·41), restrained eating (1·16, 1·06-1·27), and compensatory behaviours (1·18, 1·08-1·30) in adolescence. Greater emotional overeating in early childhood increased the odds of compensatory behaviours (1·18, 1·06-1·33). By contrast, greater satiety responsiveness in early childhood decreased the odds of compensatory behaviours in adolescence (0·89, 0·81-0·99) and uncontrolled eating (0·86, 0·78-0·95) in adolescence. Slower eating in early childhood decreased the odds of compensatory behaviours (0·91, 0·84-0·99) and restrained eating (0·90, 0·83-0·98) in adolescence. No other associations were observed. INTERPRETATION: In this study, higher food responsiveness in early childhood was associated with a higher likelihood of self-reported eating disorder symptoms in adolescence, whereas greater satiety sensitivity and slower eating were associated with a lower likelihood of some eating disorder symptoms. Appetitive traits in children might be early neurobehavioural risk factors for, or markers of, subsequent eating disorder symptoms. FUNDING: MQ Mental Health Research, Rosetrees Trust, ZonMw.

RESUMEN

PURPOSE: The purpose of this retrospective study was to determine the effectiveness of pericapsular nerve group (PENG) block for pain control intraoperatively in patients undergoing total hip arthroplasty (primary-27130) (THA), compared to opioid based analgesia. The PENG block is an emerging regional anesthesia technique that aims to provide hip analgesia with preservation of motor function offering benefit over existing regional techniques while reducing overall opioid requirements. DESIGN: A retrospective cohort chart review and analysis. METHODS: A single-site, retrospective chart review was performed for individuals undergoing THAs at a community hospital from 2019 to 2022 (N = 123). Anesthesia records were collected and observed for multiple data points including peripheral nerve block provided, micrograms of fentanyl administered before and during the case, additional medications given, and additional nerve blocks performed. The demographic data included birth date, sex, and procedure date. FINDINGS: For statistical analysis only, patients receiving PENG (59) were compared to those receiving only intravenous analgesia (No Block-57). Statistically and clinically significant reductions in fentanyl administration and morphine equivalents were found in the population receiving PENG blocks. The mean intraoperative fentanyl given to the No Block group was 292.98 mcg versus 50.42 mcg in the PENG group (P < .05). Mean morphine equivalents given in the No Block group was 23.51 mg versus 11.21 mg in the PENG group (P < .05). CONCLUSIONS: Receiving a PENG block preoperatively resulted in clinically and statistically significant opioid reduction during the perioperative period when compared with patients who did not receive a regional block.

RESUMEN

BACKGROUND: Research on feeding in early childhood has focused primarily on parent-child dyadic interactions, despite parents enacting these practices within the complex dynamic of the family system. OBJECTIVE: Using a sibling design, this study aimed to assess how parents may adapt their food parenting practices for siblings in response to differences in their eating behaviors. DESIGN: A cross-sectional online survey was conducted between October and December 2022. PARTICIPANTS/SETTING: Data were collected from parents (97.5% women) in Australia with 2 children aged 2 to 5 years (n = 336 parents and n = 672 children). MAIN OUTCOME MEASURES: Survey items were completed for each sibling, and included four subscales of the Children's Eating Behaviour Questionnaire and seven subscales of the Feeding Practices and Structure Questionnaire-28. STATISTICAL ANALYSES PERFORMED: Multiple linear regression models examined associations between within-sibling pair differences in child eating behaviors and food parenting practices, adjusting for differences in child body mass index z score, age, gender, and early feeding method. RESULTS: Within-sibling pair differences in eating behaviors were associated with differences in some food parenting practices. For the fussier sibling, parents reported using more control-based practices, including persuasive feeding, reward for eating, and reward for behavior, and less of the structure-based practice, family meal settings (P values < 0.001). Similar directions of associations were found for persuasive feeding, reward for eating, and family meal settings with siblings who were slower eaters or more satiety responsive (P values < 0.007); however, no significant differences in reward for behavior were observed in relation to sibling differences in these eating behaviors. For the more food responsive sibling, parents reported using more control-based practices, including reward for behavior and overt restriction (P values < 0.002). CONCLUSIONS: Within families, parents may adapt certain practices in response to differences in their children's eating behaviors. Interventions promoting responsive feeding should be designed to acknowledge the integral role of siblings in shaping parents' feeding decisions.

RESUMEN

OBJECTIVE: We conducted a scoping review of interventions designed to improve the health care experiences of autistic individuals and assessed the methodology and outcomes used to evaluate them. METHODS: Literature from January 2005 to October 2020 was searched using PubMed, Excerpta Medica dataBASE (EMBASE), Cumulated Index to Nursing and Allied Health Literature (CINAHL), PsycINFO as well as hand searching. Studies included described an intervention for autistic individuals in inpatient or outpatient settings and evaluated the intervention using standardized methodology. Results were exported to Covidence software. Ten reviewers completed abstract screening, full text review, and then systematic data extraction of the remaining articles. Two reviewers evaluated each article at each stage, with a third reviewer arbitrating differences. RESULTS: A total of 38 studies, including three randomized controlled trials (RCTs) were included. Twenty-six (68%) took place in dental, psychiatric, or procedural settings. Interventions primarily focused on visit preparation and comprehensive care plans or pathways (N = 29, 76%). The most frequent outcome was procedural compliance (N = 15), followed by intervention acceptability (N = 7) and parent satisfaction (N = 6). Two studies involved autistic individuals and caregivers in study design, and no studies assessed racial/ethnic diversity on intervention impact. CONCLUSIONS: Well-designed evaluations of interventions to support autistic individuals in pediatric health care settings are limited. There is a need to conduct large multi-site intervention implementation studies.
