Background Strengthening social integration could prevent suicidal behavior. However, minimal research has examined through relationship network structure. To address this important gap, we tested whether structural characteristics of school networks predict rates ideation and attempts. Methods In 38 US high schools, 10,291 students nominated close friends trusted adults to construct networks. We used mixed‐effects logistic regression models test individual student likelihood ( SI ) suicide...
Decisions to perform moderate-to-vigorous physical activity (MVPA) involve behavioral cognitive processes that may differ within individuals depending on the situation.Ecological momentary assessment (EMA) was used examine relationships of cognitions (ie, self-efficacy, outcome expectancy, intentions) with MVPA (measured by accelerometer). A sample 116 adults (mean age, 40.3 years; 72.4% female) provided real-time EMA responses via mobile phones across 4 days. Multilevel models were test...
<h3>Importance</h3> Nonnutritive sweeteners (NNSs) are used as an alternative to nutritive quench desire for sweets while reducing caloric intake. However, studies have shown mixed results concerning the effects of NNSs on appetite, and associations between sex obesity with reward appetitive responses NNS compared sugar unknown. <h3>Objective</h3> To examine neural reactivity different types high-calorie food cues (ie, sweet savory), metabolic responses, eating behavior following consumption...
Accurate component orientation and restoration of hip biomechanics remains a continuing challenge in total arthroplasty (THA). The goal this study was to analyze the accuracy/reproducibility novel CT-free pin-less robotic-assisted THA (RA-THA) platform compared manual (mTHA). This matched-pair cadaveric RA-THA system mTHA (n = 33/arm), both using assistance fluoroscopic imaging, group 14 high-volume surgeons. In groups, surgeons were asked aim for 40°/15° cup inclination/version, 0 mm leg...
Background Epidural steroid injections (ESIs) are a common conservative treatment for mitigating radicular pain and often used to relieve pain, increase function, improve mobility. However, their efficacy duration of relief relatively unclear because the variability in clinical indications, injection techniques, mixtures, number allowable injections, lack standard objective outcome measures literature. Objectives This study aimed characterize effectiveness ESIs improving measured with...
sFLT-1 has been implicated in the pathogenesis of HDP. We aimed to examine role maternal and fetal polymorphisms risk HDP severe-spectrum disease. Cases (143) controls (169) from mother-baby dyads were recruited at Los Angeles County Women's Children's Hospital (WCH). severe disease (99) (31) mother-father-baby triads through HELLP syndrome websites. Four SNPs (rs7993594, rs3751395, rs7983774, rs664393) genotyped. Data was analyzed using a log-linear regression model Haplin package R....
Abstract Home visiting programs (HVPs) provide services to pregnant individuals and parents of young children improve families’ health well-being. However, little is known about these social contexts. This study explores the networks dietary intake mothers enrolled in a HVP, focusing on support undermining. Cross-sectional data from 76 HVP Los Angeles County were collected by interview, using validated measures. Almost all (95.7%) had one or more supporters, while 55.1% underminers. Some key...
ABSTRACT The COVID‐19 pandemic and the stay‐at‐home order may have impacted risk of child physical abuse (CPA). Analyzing injury types in suspected CPA cases before during can provide valuable insights. objective this study is to compare incidences injuries detected by skeletal surveys at a large academic children's hospital pandemic. compared proportion specific sites, traumas, demographic characteristics using Pearson's chi‐squared Fisher's exact tests. A total 479 patients who underwent...
Introduction: Children and adolescents with congenital adrenal hyperplasia (CAH) are at increased risk for obesity exhibit differences in brain regions associated food reward decision-making. We aimed to understand dietary decision-making between youth CAH compared controls. Methods: 37 (12.2 ± 3.1y, 59.5% female) 100 controls (11.7 2.4y, 57% rated 30 low- high-calorie foods health, taste, liking. Participants then chose pair trials using a mouse-tracking paradigm; 75 were discordant health...
Abstract Hypoxia-inducible factor 1-alpha (HIF-1α) regulates cellular responses to hypoxia. Overexpression of HIF-1α is associated with abnormal placental trophoblast invasion and hypertensive disorders pregnancy. We evaluated the putative association between polymorphisms haplotypes in parental child genes risk severe-spectrum Case ( N = 179) control 34) mother-father-child triads were recruited by an internet-based method. Cases defined as HELLP (Hemolysis, Elevated Liver enzymes Low...
Religiousness has long been found beneficial for mental health, although its protective effects may be attenuated sexual minorities. We sought to examine the associations between religiousness and depression whether these were moderated by religious affiliation and/or orientation. analyzed dataset ( N = 103,161 undergraduate graduate students) from Healthy Minds Study (2020-2021), which was an online survey administered at 140 higher education institutions across United States. used...
The longitudinal trajectory of body mass index (BMI) and brain structure development during peri-adolescence is not clearly defined in offspring prenatally exposed to gestational diabetes mellitus (GDM) vs. un-exposed offspring. Participants between age 9 10 years (N=9,583) were included from the Adolescent Brain Cognitive Development (ABCD) Study followed yearly though 4-year follow-up. GDM puberty status self-reported. BMI was calculated yearly, MRI assessed biennially. Mixed-effects...
Abstract Introduction Burn recovery can involve extensive rehabilitation after discharge from acute care, with physical therapy (PT) and occupational (OT) playing key roles in improving function reintegration. Outpatient may occur at burn centers or external facilities without PT/OT specialists due to factors like geography insurance. Limited data exists on how these settings impact patient-reported outcomes. This study aims explore the where patients receive outpatient assess differences...
Researchers often estimate the performance capabilities of animals using a small number trials per individual. This procedure inevitably underestimates maximum performance, but few studies have examined magnitude this effect. In study we explored effects intraindividual variation and individual sample size on estimation locomotor parameters. We measured sprint speed lizard Sceloporus occidentalis at two temperatures (20 degrees C 35 C), obtaining 20 measurements Speed did not vary...
Background: Peer-led interventions have been applied to prevent various health behavior problems and may be an important complement individual-level suicide prevention approaches. Sources of Strength trains student "peer leaders" in secondary schools conduct activities that encourage other students build healthy social bonds strengthen help-seeking norms. Prior work examining diffusion peer-led programs has focused on youths' closeness peer leaders but minimally factors such as connections...
Using social networks to inform prevention efforts is promising but has not been applied vaping. To address this gap, we pilot tested the peer-led Above Influence of Vaping (ATI-V) and examined diffusion through 8th grade in three schools. Fifty students, nominated trained as Peer Leaders, implemented campaigns informed by communication science, including gain-loss messaging norming. Across schools, 86-91% students (N = 377) completed measures (pre-post) electronic vaping product (EVP) use...
Abstract The San Francisco Department of Public Health was the first to issue guidance on use doxycycline for post-exposure prophylaxis against STIs in at-risk populations. We investigated association between issuance these guidelines and rates male rectal chlamydia, gonorrhea, adult syphilis.
