Assessment of Binge Eating Behavior, Body Shape Concerns, and Associated Factors among Female Adolescents of Northern Saudi Arabia: A Cross-Sectional Study.

Globally, binge eating behavior has emerged as a significant public health concern, especially among female adolescents. Body shape concerns in female adolescents can lead to body dissatisfaction and other mental health issues. Using a cross-sectional study design, we evaluated the frequency of binge eating behavior, body shape concerns, and associated factors among 400 female adolescents. We utilized a pretested Arabic binge eating scale (BES) and a body shape questionnaire-shorter version (BSQ-8C) to collect the required data. We performed Spearman's correlation analysis to find the strength and direction of the correlation between the BES and BSQ-8C scores. Finally, we applied binomial logistic regression analysis to identify the predictors of body shape concerns. Of the studied participants, 5.5% and 6.2% had medium and severe binge eating behavior. We found a significant positive correlation between the BES and BSQ-8C scores (rho = 0.434, p < 0.001). Also, we found that body shape concerns were significantly higher among the monthly family income category of 5000 to 7000 SAR (p = 0.005), the severe binge eating categories (p = 0.009), and obese adolescents (p = 0.001). The present study results can be applied to the development of focused interventions and strategies to address these concerns in this group.

Influencing factors for postpartum depression in women with gestational diabetes mellitus.

It remains undefined about the association between gestational diabetes mellitus (GDM) and postpartum depression (PPD). Hence, a cross-sectional study was conducted to evaluate the association between GDM and PPD among pregnant women and to investigate the influencing factors for PPD. From June 2021 to June 2022, 205 parturients with GDM and 201 without GDM were included in the study as the GDM group and the control group, respectively. The collected data from the general information questionnaire and Self Rating Depression Scale (SDS) were statistically analyzed based on binomial logistic regression analyses and generalized linear mixed models (GLMMs). Age at delivery, gestational age, glycosylated hemoglobin, triglyceride, SDS, and proportions of women who had a history of induced abortion or GDM were significantly different between the GDM group and control group (P<0.05). The incidence of PPD in the GDM group was significantly higher than that in the control group. The neonatal body weight and triglyceride in GDM women with PPD were significantly lower than those in GDM women without PPD (P<0.001). The univariate logistic regression analysis demonstrated that educational age was a protective factor, while glycosylated hemoglobin and GDM were risk factors for PPD. The multiple linear regression analysis revealed that neonatal body weight (OR=-0.904, 95%CI: -1.657 to -0.152, P=0.019) and educational age (OR=-0.166, 95%CI: -0.306 to -0.025, P=0.021) were protective factor, while GDM (OR=1.854, 95%CI: 1.027-2.681, P<0.0001) was a risk factor for PPD. GDM may be associated with PPD. Neonatal body weight and educational age were protective factors for PPD, and GDM was a risk factor for PPD. Therefore, more attention should be paid to the mental health status of women with GDM, especially those with lesser educational age and lower neonatal body weight.

Factors Affecting Arterial Stiffness and Brachial-Ankle Pulse Wave Velocity in Patients With Type 2 Diabetes.

Background We defined the progression of atherosclerosis in patients by brachial-ankle pulse wave velocity (ba-PWV) and determined the relationship between ba-PWV and body composition factors, muscle strength, and patient characteristics. Methodology The arterial stiffness index, body composition, anthropometric parameters, blood test data, and background factors were evaluated in 109 patients with type 2 diabetes mellitus (T2DM). Statistical analysis was conducted using logistic regression analysisand analysis of covariance (p < 0.05). Results The mean age of the participants was 62.87 ± 12.11 years, body mass index (BMI) was 25.72 ± 4.35 kg/m²,ba-PWV was 1653.08 ± 366.55 cm/s, systolic blood pressure was 138.87 ± 16.74 mmHg, the number of years of disease was 11.17 ± 9.51 years, and hemoglobin A1c value was 6.90 ± 0.74%. Binomial logistic regression analysis of ba-PWV divided into two groups by arterial stiffness index, ≥ (or <) 1,400 cm/s, showed systolic blood pressure (odds ratio = 1.11, 95% confidence interval = 1.05-1.18, p < 0.001), BMI, and number of years of disease were significant independent variables. The cut-off value for BMI was 26.28 kg/m². BMI was a significant explanatory factor for ba-PWV in the analysis of covariance (p < 0.001). Conclusion BMI was associated with the incidence of atherosclerosis in patients with T2DM. We proposed a cut-off value for BMIbelow which the atherosclerosis index increased, a result that may reflect the influence of the metabolic paradox.

Relationship of work-related and leisure-based screen time with obesity: a cross-sectional study on adults including older adults.

The relationship between screen time (ST) and obesity has been demonstrated; however, few studies have differentiated between work-related and leisure-based use in Japanese adults, including older adults. This study aimed to examine the relationship between both work-related and leisure-based ST and obesity in adults. This cross-sectional study was based on a questionnaire survey conducted in 2018. Overall, 9947 adults were invited; 3161 participants (31.8%) returned the questionnaire. Finally, 2488 participants (597 younger men (YM), 792 younger women (YW), 542 older men (OM), 557 older women (OW)) were included. The main exposures were work-related, leisure-based, and total ST. The outcome was obesity (body mass index ≥ 25 kg/m2). Log-binomial regression analysis was used to calculate prevalence ratios (PRs) and confidence intervals (CIs) for obesity with 1-h increments of each ST. Analyses were conducted in all participants and subgroups comprising YM, YW, OM, and OW. Total ST was significantly associated with obesity in all participants (PR (95% CI) 1.07 (1.04-1.10), YM (1.05 (1.01-1.10)), OM (1.13 (1.05-1.22)), and OW (1.13 (1.02-1.26)). Work-related ST was significantly associated with obesity in all participants (1.08 (1.04-1.12)), YM (1.06 (1.00-1.12)), and OM (1.24 (1.08-1.42)). Leisure-based ST was significantly associated with obesity in all participants (1.09 (1.04-1.14)), YM (1.09 (1.00-1.18)), and YW (1.10 (1.01-1.20)). ST is associated with obesity in Japanese adults including older adults; particularly, work-related ST is associated with obesity in men, and leisure-based ST, in younger individuals.

Relative score of early neurological deterioration in perforator artery infarction: a retrospective study

Background and aimsCompared to small vessel occlusion (SVO) patients, branch atheromatous disease (BAD) patients are more likely to develop early neurological deterioration (END). Stroke patients with END have a poor prognosis. Initial clinical features/radiological findings are often insufficient to distinguish between BAD and SVO; therefore, they may not detect END. In this retrospective study, we investigated relative factors for END in perforator artery infarction and created a scoring system for END in these patients.MethodsWe extracted data from stroke patients with perforator artery infarction admitted to the Department of Neurology at Juntendo University between January 2016 and December 2022. We examined factors, such as the presence of SVO and BAD, leading to END. Variables with a P-value < 0.1 on univariate analysis were entered into binominal logistic regression analysis.ResultsOf the 1,420 stroke patients admitted over a 7-year period, 201 with perforator infarction were included in this study. END was found in 27 of 201 patients (13.4%). Binominal logistic regression analysis of background factors less than p < 0.1 revealed that age > 69 (P = 0.032; odds ratio [OR], 3.941; 95% confidence interval [CI], 1.126–13.769), body mass index < 23.8 (P = 0.041; OR, 3.183; 95%CI, 1.049–9.654), and pretreatment with anti-platelets (P = 0.003; OR, 5.183; 95%CI, 1.783–15.071) were significant factors. Regarding anti-platelet therapy, END was observed in 34.4% of patients administered aspirin and 35.0% administered clopidogrel. Initial infarct lesion size over 15 mm on initial MRI had a P value of 0.076 in univariate analysis and an odds ratio of 1.330 (95% CI 0.471–3.755; P = 0.590) in binomial logistic regression analysis. The length of stay and modified Rankin Scale at discharge were significantly exacerbated in the END group. Creating a scoring system with 1 point for each relevant factor (pEND score), significant correlations were obtained with ROC curves, and over 2 points produced the highest sensitivity and specificity for detecting END.ConclusionPatients with high pEND scores may require intensive care from early hospitalization. In addition, the occurrence of stroke during anti-platelet therapy suggests the need for alternative treatment.

Community-Based Residential Relocation in Middle and Older Age: A United States-China Comparison Study on Its Predictors and Associated Mortality Risk.

This study compared the United States and China in examining the predictors of community-based residential relocation and its associated mortality risk. Data from the 2010 to 2018 US Health and Retirement Study and from 2011 to 2018 China Health and Retirement Longitudinal Study were used (NUS = 20,292 and NChina = 11,694). Community-dwelling respondents (aged 50+) reported whether they had relocated and were followed up until 2018. Log-binomial regression and Cox survival analysis were used. In both countries, younger age, higher education, urban residence, and being a renter were associated with higher likelihood of relocation. Community-based relocation was associated with a lower mortality risk (US: HR = 0.63, 95% CI = 0.57, 0.70; China: HR = 0.40, 95% CI = 0.31, 0.50), and this association was significantly stronger in China compared to the United States. Common predictors of community-based relocation were found in the United States and China. The relocation-related survival advantages may be attributed to a better post-move adaptation and living environment.

Variations in the Association between Economic Distress and Anxiety by Availability of Emergency Cash Reserves: Findings from a Longitudinal Study

Objective: 1) to describe the extent that experience of economic distress is associated with incidence of anxiety, and; 2) modification of the mentioned association by availability of emergency cash reserves. Material and Methods: We conducted a longitudinal study using two phone-based surveys in the general population of Thailand in April and May, 2021. We analyzed data using descriptive statistics and log-binomial regression analyses. Results: There were 1135 persons who met the inclusion criteria and participated in both surveys (non-participation at baseline=31.7%; loss-to-follow-up=420/1555=14.4%). The association between economic distress and anxiety was stronger among participants with no emergency cash reserves (Adjusted RR=2.05, 95% CI=0.86, 4.90) and more moderate among participants with emergency cash reserves (Adjusted RR=1.70, 95% CI=0.31, 9.43). Conclusion: The study results appeared to support our hypothesis despite lack of statistical significance. However, the lack of adjustment for other predictors of anxiety, and the lack of ability to generalize to other phases of the COVID-19 pandemic should be considered as caveats in the interpretation of our study findings.

Early versus late response to PD-1-based immunotherapy in metastatic melanoma

BackgroundImmune checkpoint inhibition (ICI) currently is the most effective treatment to induce durable responses in metastatic melanoma. The aims of this study are the characterization of patients with early, late and non-response to ICI and analysis of survival outcomes in a real-world patient cohort. MethodsPatients who received PD-1-based immunotherapy for non-resectable stage-IV melanoma in any therapy line were selected from the prospective multicenter real-world DeCOG study ADOREG-TRIM (NCT05750511). Patients showing complete (CR) or partial (PR) response already during the first 3 months of treatment (Early Responders, EarlyR) were compared to patients showing CR/PR at a later time (Late Responders, LateR), a stable disease (SD) and to patients showing progressive disease (Non-Responders, NonR). ResultsOf 522 patients, 8.2 % were EarlyR (n = 43), 19.0 % were LateR (n = 99), 37.0 % had a SD (n = 193) and 35.8 % were NonR (n = 187). EarlyR, LateR and SD patients had comparable baseline characteristics. Multivariate logbinomial regression analyses adjusted for age and sex revealed positive tumor PD-L1 (RR=1.99, 95 %-CI=1.14–3.46, p = 0.015), and normal serum CRP (RR=1.59, 95 %-CI=0.93–2.70, p = 0.036) as independently associated with the achievement of an early response compared to NonR. The median progression-free and overall survival was 46.0 months (95 % CI 19.1; NR) and 47.8 months (95 %-CI 36.9; NR) for EarlyR, NR (95 %-CI NR; NR) for LateR, 8.1 months (7.0; 10.4) and 35.4 months (29.2; NR) for SD, and 2.0 months (95 %-CI 1.9; 2.1) and 6.1 months (95 %-CI 4.6; 8.8) for NonR patients. ConclusionLess than 10 % of metastatic melanoma patients achieved an early response during the first 3 months of PD-1-based immunotherapy. Early responders were not superior to late responders in terms of response durability and survival.

Improvement of social frailty is associated with stability of nonparametric characteristics of the rest-activity rhythm and improvement of the usual walking ability in the elderly

ABSTRACT Our study, conducted between April 2022 and January 2024, was aimed at clarifying components of the rest-activity rhythm (RAR) involved in improvement of social frailty state before or after a 3-month multi-component exercise intervention in the elderly. Participants were recruited from the general population in Akita prefecture, Japan. We administered a four-item social frailty screening questionnaire to classify the severity of social frailty in each participant before and after the 3-month intervention. The RAR parameters were measured on an Actiwatch Spectrum Plus device worn by the subjects for 7 continuous days. As the final sample, 65 participants classified into the improved/maintained group (n = 36) or the deteriorated group (n = 29) according to the change in the social frailty classification after the intervention were included in the analysis. The results of a binomial logistic regression analysis showed significantly higher values of interdaily stability (IS) and usual walking speed at the post-test after the intervention. Based on our findings, we propose that stability of the rest-activity rhythm related to synchronization with external stimuli (such as social effect and physical activity) might have clinical impact on improvement of social frailty state in elderly community-dwellers.

The Predictive Accuracy of Anogenital Distance and Genital Tubercle Angle for First-Trimester Fetal Sex Determination.

Early identification of fetal gender is crucial for managing gender-linked genetic disorders. This study aimed to evaluate the predictive performance of anogenital distance (AGD) and genital tubercle angle (GTA) for fetal sex determination during the first trimester. A multicenter retrospective cohort study was conducted on 312 fetal cases between 11 and 13 + 6 weeks of gestation from two tertiary hospitals. AGD and GTA measurements were taken from midsagittal plane images using ultrasound, with intra- and inter-reader reproducibility assessed. Binomial logistic regression and ROC curve analysis were employed to determine the diagnostic performance and optimal cutoff points. AGD had a mean of 7.16 mm in male fetuses and 4.42 mm in female fetuses, with a sensitivity of 88.8%, specificity of 94.4%, and an area under the ROC curve (AUC) of 0.931 (95% CI: 0.899-0.962) using 5.74 mm as a cutoff point. For GTA, the mean was 35.90 degrees in males and 21.57 degrees in females, with a sensitivity of 92%, specificity of 84.7%, and an AUC of 0.932 (95% CI: 0.904-0.961) using 28.32 degrees as a cutoff point. The reproducibility results were excellent for AGD (intra-operator ICC = 0.938, inter-operator ICC = 0.871) and moderate for GTA (intra-operator ICC = 0.895, inter-operator ICC = 0.695). The findings suggest that AGD and GTA are reliable markers for early fetal sex determination, with AGD showing higher reproducibility. The findings highlight the feasibility and accuracy of these non-invasive sonographic markers and their potential usefulness in guiding timely interventions and enhancing the management of gender-linked genetic conditions.

Exploring factors associated with failure of totally implanted vascular access devices in a regional and rural health service: a retrospective case–control study

BackgroundThe assessment and management of totally implanted vascular access devices (TIVAD) prior to the administration of medications/fluids are vital to ensuring the risk of harm is mitigated. While numerous guidelines...

Association Between Korean Adults' Electronic Health Literacy and Active Participation in Health Decision-Making.

This study aimed to investigate the association between Korean adults' electronic health literacy and active participation in health decision-making while communicating with healthcare providers. A total of 421 adults 18 years and older were recruited from a survey panel developed by a survey company and completed an online survey asking about individual characteristics and electronic health literacy. Data were analyzed using descriptive statistics, independent-samples t tests, analysis of variance, and binomial logistic regression analysis. In results, for every one-unit increase in electronic health literacy, the rate of active participation in health decision-making was likely to increase by 3.62 times compared with the rate of passive participation in health decision-making. It was also likely to increase in those with a college degree or higher, those who used both Web sites and YouTube, those who perceived online health information to be useful, those who actively participated as a patient, and those with a desire to actively participate as a patient. To encourage active participation in health-related situations or decision-making processes, educational programs or interventions to improve individuals' electronic health literacy are needed. Healthcare providers must ensure that individuals feel comfortable expressing their preferences, needs, and values.

Vagus nerve electroneurogram-based detection of acute kainic acid induced seizures.

Seizures produce autonomic symptoms, mainly sympathetic but also parasympathetic in origin. Within this context, the vagus nerve is a key player as it carries information from the different organs to the brain and vice versa. Hence, exploiting vagal neural traffic for seizure detection might be a promising tool to improve the efficacy of closed-loop Vagus Nerve Stimulation. This study developed a VENG detection algorithm that effectively detects seizures by emphasizing the loss of spontaneous rhythmicity associated with respiration in acute intrahippocampal Kainic Acid rat model. Among 20 induced seizures in six anesthetized rats, 13 were detected (sensitivity: 65%, accuracy: 92.86%), with a mean VENG-detection delay of 25.3 ± 13.5 s after EEG-based seizure onset. Despite variations in detection parameters, 7 out of 20 seizures exhibited no ictal VENG modifications and remained undetected. Statistical analysis highlighted a significant difference in Delta, Theta and Beta band evolution between detected and undetected seizures, in addition to variations in the magnitude of HR changes. Binomial logistic regression analysis confirmed that an increase in delta and theta band activity was associated with a decreased likelihood of seizure detection. This results suggest the possibility of distinct seizure spreading patterns between the two groups which may results in differential activation of the autonomic central network. Despite notable progress, limitations, particularly the absence of respiration recording, underscore areas for future exploration and refinement in closed-loop stimulation strategies for epilepsy management. This study constitutes the initial phase of a longitudinal investigation, which will subsequently involve reproducing these experiments in awake conditions with spontaneous recurrent seizures.

Development and validation of a clinical prediction rule for walking independence in hospitalized older adults with a vertebral compression fracture.

No reports on factors or Clinical prediction rules (CPRs) associated with walking independence among patients with vertebral compression fractures (VCFs) are available. Evidence regarding epidemiological walking independence rates is also sparse. Here, we sought to (i) obtain epidemiological data on the probability of inpatients with VCFs achieving walking independence, and (ii) develop and validate a CPR to determine walking independence in hospitalized patients with VCFs. We conducted a retrospective cross-sectional observational study of patients aged ≥60years who were hospitalized for VCF at four hospitals in Japan in 2019-2022. The outcome was walking independence at discharge. We performed a binomial logistic regression analysis to assess predictors of walking independence. Five independent variables were entered: age, American Society of Anesthesiologists physical status, cognitive function, Berg Balance Scale (BBS), and 10-m walking test. Among the independent variables that were significant, we converted the continuous variables to binary data by calculating cut-off values and then created the CPR. The area under the curve (AUC) was calculated as the measure of the CPR's diagnostic accuracy, and internal validation was conducted by bootstrapping. Of the 240 patients, 188 (78.3%) achieved walking independence. Cognitive function and the BBS score (with a cut-off of 45 points) were identified as significant predictors. We created a CPR using these two items (0-2 points). The CPR's AUC was 0.92 (0.874-0.967), and internal validation by bootstrapping yielded a mean AUC of 0.919 with a slope of 0.965. The walking independence rate of patients with a VCF during hospitalization was 78.3%, with cognitive function and BBS being predictors. The developed CPR performed well enough to retrospectively predict walking independence in VCF patients. The BBS cut-off value and the CPR may serve as useful indicators for clinicians to predict VCF patients' walking independence.

Exploring the association between adherence to home-based exercise recommendations and recovery of nonspecific low back pain: a prospective cohort study

BackgroundAdherence to home-based exercise (HBE) recommendations is critical in physiotherapy for patients with low back pain (LBP). However, limited research has explored its connection with clinical outcomes. This study examined how adherence to HBE relates to changes in physical function, pain intensity, and recovery from LBP in patients undergoing physiotherapy treatment.MethodsData from a multicenter cluster randomized controlled trial in the Netherlands involving patients with LBP from 58 primary care physiotherapy practices were used. Adherence to HBE was assessed with the Exercise Adherence Scale (EXAS) at each treatment session. Previously identified adherence trajectories served as a longitudinal measure of adherence and included the classes “declining adherence” (12% of participants), “stable adherence” (45%), and “increasing adherence” (43%). The main outcomes included disability (Oswestry Disability Index), pain (Numeric Pain Rating Scale), and recovery (pain-free for > 4 weeks), which were measured at baseline and after three months. Linear and binomial logistic regression analyses adjusted for confounders were used to examine adherence–outcome relationships.ResultsIn the parent trial, 208 participants were included. EXAS scores were available for 173 participants, collected over a median of 4.0 treatment sessions (IQR 3.0 to 6.0). Forty-five (28.5%) patients considered themselves to have recovered after three months. The median changes in the Oswestry Disability Index and Numeric Pain Rating Scale were − 8 (IQR − 1 to -20) and − 2 (IQR − 0.5 to -4), respectively. The mean EXAS scores varied among patient classes: “declining adherence” (46.0, SD 19.4), “stable adherence” (81.0, SD 12.4), and “increasing adherence” (39.9, SD 25.3), with an overall mean of 59.2 (SD 25.3). No associations between adherence and changes in physical functioning or pain were found in the regression analyses.ConclusionsNo association between adherence to HBE recommendations and changes in clinical outcomes in patients with LBP was found. These findings suggest that the relationship between adherence to HBE recommendations and treatment outcomes may be more complex than initially assumed. Further research using detailed longitudinal data combined with qualitative methods to investigate patient motivation and beliefs may lead to a deeper understanding of the relationship between adherence and clinical outcomes in patients with LBP.

Missed Opportunity or Cause for Concern? Methamphetamine Use Is Associated With Greater Interest in Event-Driven PrEP Among Sexual Minority Men.

Our study assessed the association between methamphetamine (i.e., crystal meth, CM) use and awareness and interest in event-driven (ED) PrEP among HIV-negative and those with unknown serostatus cisgender males and transgender people. We performed log-binomial regression analysis to predict awareness (i.e., having heard of ED PrEP) and being interested in ED PrEP. We found that participants who recently used CM were less likely to know of ED PrEP (aPR = 0.83, 95% CI [0.69, 0.99]) but more interested in ED PrEP (aPR = 1.12, 95% CI [1.01, 1.30]), after accounting for demographic and HIV-related behaviors. Opportunities to expand PrEP uptake and improve adherence among individuals who report CM use are essential to impact the HIV epidemic significantly. Continued research on the needs and best practices to work with this community is needed to ensure a successful rollout and implementation of ED PrEP.

Assessing predictors of adequate individual buprenorphine maintenance dosage for the treatment of opioid use disorder: Listening to the patient

ObjectiveDose optimization plays a key role in determining clinical outcomes in patients on opioid agonist treatment (OAT). The objective of this study was to identify the variables independently associated with buprenorphine/naloxone (B/N) dose adequacy in patients with opiate use disorder (OUD). MethodCross-sectional study of a convenience sample of patients with OUD treated with B/N (n = 315) in four regions in Spain. The Opiate Dosage Adequacy Scale (ODAS) was used to determine B/N dose adequacy. The ODAS evaluate the six components of the “dose adequacy” construct, as follows: continued use of heroin; narcotic blockade or crossed tolerance; objective opioid withdrawal symptoms (OWS); subjective OWS; craving for heroin; and overmedication. A binomial logistic regression analysis was performed to identify the variables associated with the condition “ODAS Adequate B/N dose”. Participants completed a battery of instruments to assess sociodemographic, substance use, clinical, and treatment variables. ResultsThe B/N dose was considered adequate in 231 of the 315 participants (73.3 %). Two variables, satisfaction with B/N as a medication (OR=5.764, 95 % CI=2.211-15.030) and patient-perceived participation in B/N dose decisions (OR=1.790, 95 % CI=1221-2623), were independently, significantly, and positively associated with the “ODAS Adequate B/N dose” condition. While the severity of heroin dependence was significantly associated with buprenorphine dose adequacy in the bivariate analyses, significance was lost in the full regression model. ConclusionSatisfaction with B/N as a medication and patient-perceived involvement in the dose decision are associated with clinician-assessed dose adequacy. In the context of good clinical practice, it is important to take into account both of these variables to individualize the prescribed dose through a shared decision-making process.

Validation of a computed tomography diagnostic model for differentiating fibrotic hypersensitivity pneumonitis from idiopathic pulmonary fibrosis

BackgroundThe diagnosis of fibrotic hypersensitivity pneumonitis (fHP) from other interstitial lung diseases, particularly idiopathic pulmonary fibrosis (IPF), is often difficult. This study aimed to examine computed tomography (CT) findings that were useful for differentiating between fHP and IPF and to develop and validate a radiological diagnostic model. MethodsIn this study, 246 patients (fHP, n = 104; IPF, n = 142) from two institutions were included and randomly divided into the test (n = 164) and validation (n = 82) groups (at a 2:1 ratio). Three radiologists evaluated CT findings, such as pulmonary fibrosis, small airway disease, and predominant distribution, and compared them between fHP and IPF using binomial logistic regression and multivariate analysis. A prognostic model was developed from the test group and validated with the validation group. ResultsGround-glass opacity (GGO) with traction bronchiectasis (TB), honeycombing, hypoattenuation area, three-density pattern, diffuse craniocaudal distribution, peribronchovascular opacities in the upper lung, and random distribution were more common in fHP than in IPF. In multivariate analysis, GGO with TB, peribronchovascular opacities in the upper lung, and random distribution were significant features. The area under the curve of the fHP diagnostic model with the three aforementioned CT features was 0.733 (95% confidence interval [CI], 0.655–0.811, p < 0.001) in the test group and 0.630 (95% CI, 0.504–0.755, p < 0.047) in the validation group. ConclusionGGO with TB, peribronchovascular opacities in the upper lung, and random distribution were important CT features for differentiating fHP from IPF.

Neighborhood deprivation is not associated with abortion consideration or completion in patients with fetal myelomeningocele.

The objective of this study was to evaluate whether patient-level neighborhood deprivation index (NDI) was associated with termination of pregnancy consideration and completion in patients presenting with fetal myelomeningocele. This was a retrospective cohort analysis of patients with fetal myelomeningocele presenting to a fetal treatment center (FTC) in Illinois between 2018 and 2024. The exposure was NDI calculated from patient zip codes. The NDI was analyzed as both a dichotomous and ordinal exposure. The co-primary outcomes were abortion consideration prior to FTC consultation, ascertained by nurse intake, and abortion completion after consultation. Bivariate and log-binomial regression analyses were performed. Covariates were selected based on p<0.10 on bivariate analyses. Otherwise, p<0.05 indicated statistical significance. A total of 157 participants were included. Evaluation of neighborhood deprivation as a dichotomous exposure revealed no association with abortion consideration or completion. AdditionallLy, no association was found on log binomial modeling after controlling for gestational age at presentation to the FTC and maternal race or ethnicity for abortion consideration (aRR 0.87, 95% CI 0.59-1.28) or completion (aRR 0.86, 95% CI 0.59-1.28). These results were similar when treating the NDI as an ordinal exposure. Contrary to our hypothesis, NDI is not associated with abortion consideration or completion in patients with fetal myelomeningocele.

Associations Between PTSD Features and Firearm Ownership and Storage: Results From the PRImary Care Screening Methods (PRISM) Study.

Veterans and active duty service members are significantly more likely to die by suicide using firearms compared to the general population. Not-secure firearm storage (e.g., keeping guns loaded/in an unlocked location) is associated with greater risk for suicide and a third of veteran firearm owners store at least 1 personal firearm unsecured. Veterans and active duty service members are also significantly more likely to be diagnosed with posttraumatic stress disorder (PTSD) than the general population. Symptoms of PTSD are divided into 4 criteria: reexperiencing, avoidance, negative affect, and hyperarousal. Research has suggested that endorsement of hyperarousal symptoms is positively associated with unsecure firearm storage and that avoidance symptoms might be negatively associated with unsecure storage practices. The present study examined the relationship between self-reported firearm ownership and storage practices among each item from the Primary Care PTSD Screening for DSM-IV-TR (PC-PTSD-IV) to explore associations between PTSD features and firearm ownership and storage. Participants were recruited from primary care clinics across 5 military installations in the United States as part of a larger study (Mage = 45.4, SD = 16.9). Among participants (n = 2,685), most of our sample identified as male (51.3%) and white (67.3%) with 61.6% currently serving in the military, 16.8% retirees, and 21.6% family members. PTSD symptoms were assessed using the PC-PTSD-IV and a quarter met the clinical threshold for PTSD. Binomial and multinomial logistic regression analyses were used. Among completed responses, 989 (38.1%) people reported owning guns; among gun owners, 386 (39.0%) reported that they were loaded, and 352 (35.6%) reported they were loaded and unlocked. Endorsement of specific items on the PC-PTSD-IV, including those specific to hyperarousal and avoidance, was not significantly associated with storing firearms loaded and/or in nonsecure locations when controlling for military service. Non-responses to items around firearm storage practices were significantly associated with those individuals meeting the clinical threshold for PTSD according to the PC-PTSD-IV and participants currently serving had higher odds of storing at least 1 personal firearm loaded and both loaded and unlocked. Results from our study highlight similarities and departures from the previous literature on the connection between PTSD and non-secure firearm storage practices. Further research may examine (1) the relation between PTSD symptoms and firearm storage between active duty service members, retirees, and family members and (2) whether non-response to items regarding firearm ownership is systematic.
