Correlation between severity of preoperative low back pain and postoperative outcomes in lumbar disc herniation surgery: A retrospective cohort study.

Low back pain (LBP) frequently occurs in patients with lumbar disc herniation (LDH), however the extent to which discectomy ameliorates it and how preoperative LBP influences postoperative outcomes remains unclear. To evaluate the improvement in LBP and its impact on postoperative patient-reported outcome measures (PROMs). Multicenter retrospective observational study. Patients undergoing discectomy for LDH at eight hospitals from April 2017 to March 2021. Data were collected on patients' backgrounds, operative factors, and PROMs, including the Numeric Rating Scale (NRS) for pain in the low back, buttock, or leg, EuroQol 5 Dimension (EQ-5D), Oswestry Disability Index (ODI) scores, and postoperative satisfaction. Patients were categorized into mild (NRS 0-3), moderate (NRS 4-7), or severe (NRS 8-10) LBP groups. Inverse probability weighting with propensity scores was used to adjust for demographic and clinical differences between groups. Chi-square tests and one-way analysis of variance were conducted to compare background data and clinical characteristics. Additionally, multivariate logistic regression was performed to identify risk factors for less than 50% improvement in LBP. This study included 928 patients: 270 mild, 343 moderate, and 315 severe. After adjustment, preoperative NRS scores were significantly different across groups, with scores of 1.6 (SD 1.3), 5.6 (SD 1.0), and 8.8 (SD 0.9), respectively. Postoperative NRS scores also varied significantly, with worse outcomes observed in the severe group compared to the mild group, yet similar to the moderate group. A total of 46.8% of the mild group, 86.6% of the moderate group, and 72.9% of the severe group achieved a 50% decrease in NRS scores of LBP. Preoperative EQ-5D and ODI scores were significantly worse in the severe group compared to the mild or moderate groups, but postoperative scores were not significantly different between the severe and moderate groups. No significant differences in postoperative satisfaction were observed among the groups. Being female was a significant risk factor for less than 50% improvement in LBP (odds ratio = 1.56, p = 0.022). Discectomy significantly improved LBP in patients with LDH, including those with moderate or severe LBP. Patients with severe LBP showed similar improvements in PROMs as those with moderate LBP. Female gender emerged as a significant risk factor for less than optimal improvement in LBP.

Analysing Food Safety Compliance in Toronto: Identifying Current Hazards and Challenge

Abstract. This research conducts an in-depth investigation into the current state of food safety compliance in Toronto, thoroughly examining the present condition of food safety in the city. By utilizing a comprehensive dataset that includes a wide variety of dining establishments and their respective inspection results, the study employs advanced statistical methods for both analysis and visualization. These methods include the development of logistic regression models to identify significant patterns and trends. The goal is to highlight areas that require immediate attention or policy adjustments through a detailed examination of inspection reports, types of violations, violation frequencies, inspection dates, and the nature of the violations. Finally, the findings of the study strongly suggest that the government should increase the frequency of inspections, particularly during certain seasons, across various types of food businesses, and for specific types of violations, to enhance local food safety and protect the health of every Toronto resident.

Engagement in Healthcare Decision-Making and Associated Factors among Patients with Chronic Non-Communicable Diseases in Southwest Ethiopia, 2023

BackgroundChronic Non-communicable diseases require lifelong care involving patients, families, a team of their care providers, and significant others. Additionally, engaging patients in their healthcare decision-making is crucial for achieving better clinical outcomes. This study aimed to assess patients' engagement in healthcare decision-making and associated factors among adults with chronic non-communicable diseases in Southwest Ethiopia MethodsA cross-sectional study design was used among 422 participants at the public hospital of Jimma town. Study participants were consecutively recruited from May 01 to June 01, 2023. A structured Patient Activation Measure was used to measure patient engagement in healthcare decision-making. Descriptive statistics and binary logistic regression analysis describe the association between dependent and independent variables. ResultA total of 422 patients with chronic diseases participated in the study yielding a response rate of 99.3%. Slightly greater than one-third (35.8% (95% CI: 31.19, 40.41)) of participants in The study area had a high engagement in healthcare decision-making. Residence (Odd ratio 0.27; 95% confidence interval 0.137-0.534), educational level(Odd ratio 0.168; 95% confidence interval 0.064-0.443), access to information materials(Odd ratio 0.226; 95% confidence interval 0.112-0.458), duration(Odd ratio 3.864; 95% confidence interval 2.083-7.169), health literacy(Odd ratio 1.192; 95% confidence interval 1.111-1.28), and preference for autonomy(Odd ratio 1.097; 95% confidence interval 1.058-1.136) were factors statistically associated with patient engagement in healthcare decision-making. ConclusionOne-third of study participants reported high engagement in healthcare decision-making. Thus, healthcare providers should pay attention to patients with low educational levels, who do not have access to information materials, low health literacy levels, and their preference for autonomy to engage them in their healthcare decision-making.

Factors influencing the initiation of biologic therapy in children with severe asthma: Results of the pediatric asthma noninvasive diagnostic approaches (PANDA) study.

Despite the availability of biologics for severe pediatric asthma, real-life studies reporting on drivers behind initiating biologics and their alignment with the Global Initiative for Asthma (GINA) recommendations are lacking. We performed analysis within the pediatric asthma noninvasive diagnostic approaches study, a prospective cohort of 6- to 17-year-old children with severe asthma. Information was collected on demographic factors, symptom control, treatment, comorbidities, and diagnostic tests from medical records and questionnaires. We divided patients into "starters" or "nonstarters" based on the clinical decision to initiate biologics and performed multivariate logistic regression analysis to identify drivers behind initiating therapy. Additionally, we assessed patient suitability for biologics according to key factors in the GINA recommendations: Type 2 inflammation, frequency of exacerbations, and optimization of treatment adherence. In total, 72 children (mean age 11.5 ± 3.0 years, 65.3% male) were included (13 starters). Initiation of biologics was associated with a higher GINA treatment step (adjusted odds ratio's [aOR] = 5.0, 95%CI 1.33-18.76), steroid toxicity (aOR = 21.1, 95%CI 3.73-119.91), frequency of exacerbations (aOR = 1.6, 95%CI 1.10-2.39), improved therapy adherence (aOR = 1.7, 95%CI 1.10-2.46), Caucasian ethnicity (aOR = 0.20, 95%CI 0.05-0.80), ≥1 allergic sensitization (aOR = 0.06, 95%CI 0.004-0.97), and allergic rhinitis (aOR = 0.13, 95%CI 0.03-0.65). Furthermore, steroid toxicity was identified as an important factor for deviation from the current recommendations on biologic prescription. We identified multiple drivers and inhibitors for initiating biologics, and showed the clinical need for biologics in severe pediatric asthmatics suffering from steroid toxicity. These findings may help refine asthma management guidelines.

Long-Term Neurologic Outcomes in Pediatric Arterial Ischemic Stroke: The Impact of Age and Lesion Location.

The impact of age-at-stroke on outcome following pediatric arterial ischemic stroke remains controversial. We studied the interaction of age-at-stroke and infarct location and extent with long-term neurological outcomes. We conducted a longitudinal prospective outcome study of children with acute pediatric arterial ischemic stroke diagnosed from 1996 to 2016 at the Hospital for Sick Children, Toronto, Canada. Pediatric Stroke Outcome Measure scores were dichotomized as normal or abnormal (ie, mild, moderate, or severe). Outcomes were analyzed by age-at-stroke (newborn: birth to 28 days; early childhood: 29 days to 5 years; middle/late childhood: >5-18 years), and infarct location, based on each of the following: model 1: circulation (anterior/posterior); model 2: cortical versus subcortical involvement; and model 3: specific arterial territory, including infarct extent (small [<50% arterial territory] or large [≥50%]). Univariable and multivariable logistic regression models were fitted. Among 285 children, the outcome at median 6.1 years was 43.5% abnormal. Controlling for infarct location, increasing age-at-stroke was associated with increasing abnormal outcome. Model 1 demonstrated that, compared with neonates, abnormal outcomes were increased in early childhood (adjusted odds ratio [aOR], 2.91 [95% CI, 1.24-7.05]) and more so in middle/late childhood (aOR, 4.46 [95% CI, 1.71-12.13]). Outcomes were worse for combined locations, including anterior+posterior (model 1: aOR, 15.4 [95% CI, 4.49-64.63]) and cortical+subcortical (model 2: aOR, 10.7 [95% CI, 3.88-32.74]). Abnormal outcomes were also increased for anterior circulation (model 1: aOR, 14.91 [95% CI, 5.29-54.21]) and subcortical locations (model 2: aOR, 4.36 [95% CI, 1.37-14.95]). Among individual arterial territories, outcomes were best for superior division middle cerebral artery (100% normal) and worst for lateral lenticulostriate artery infarcts (47.4% abnormal; model 3: aOR, 14.2 [95% CI, 3.5-67.6]). Among survivors of pediatric stroke, abnormal long-term neurological outcome is increased with increasing age-at-stroke, supporting enhanced plasticity after focal injury to the newborn brain compared with older pediatric ages.

War-related trauma and posttraumatic stress disorder in refugees, displaced, and nondisplaced people during armed conflict in Sudan: a cross-sectional study

BackgroundThe ongoing armed conflict in Sudan has caused mass displacement, affecting mental health. This study aimed to assess the prevalence of posttraumatic stress disorder (PTSD) and trauma among refugees, internally displaced, and nondisplaced people, while also examining the link between displacement type, PTSD severity, and associated factors.MethodsThis cross-sectional study used the Posttraumatic Stress Disorder Checklist for DSM-5 to assess PTSD symptoms and the General Health Questionnaire-28 to evaluate depression. Data were collected from 642 participants, targeting general social media groups for those within Sudan and specific groups for refugees outside the country. Sociodemographic and trauma event data were also gathered. Data analysis was conducted using SPSS, applying one-way ANOVA and independent t-tests to compare PTSD and depression. Binary logistic regression identified associations between sociodemographic factors and PTSD symptoms.ResultsAmong the 642 participants, 46.3% were internally displaced people (IDP), 42.1% were refugees, and 11.7% were non-displaced individuals. Clinically significant PTSD symptoms were identified in 36.6% of the participants. Refugees had a significantly greater percentage of traumatic events (M = 4.31, SD = 2.605, p < .01). Depression symptoms were found to be strongly associated with clinically significant PTSD (p < .001). Factors significantly linked to depression symptoms included female gender (p = 0.015), being single (p = 0.048), younger age (p = 0.036), dissatisfaction with living conditions (p < 0.001), and unemployment (p = 0.021). Dissatisfaction with living conditions also significantly influenced the likelihood of developing PTSD (p < .001).ConclusionThe study found that 36.6% of participants experienced PTSD, with refugees having a 1.4 times greater risk of developing PTSD compared to IDP and non-displaced individuals. Traumatic events were moderately correlated with PTSD symptoms, though non-displaced individuals had higher exposure to such events. These findings highlight the need for targeted mental health interventions, particularly for refugees and those affected by traumatic events. Further research using probability sampling is necessary to confirm these results and inform more effective mental health policies and programs for displaced populations.

Boosting the accuracy of existing models by updating and extending: using a multicenter COVID-19 ICU cohort as a proxy

Most published prediction models for Coronavirus Disease 2019 (COVID-19) were poorly reported, at high risk of bias, and heterogeneous in model performance. To tackle methodological challenges faced in previous prediction studies, we investigated whether model updating and extending improves mortality prediction, using the Intensive Care Unit (ICU) as a proxy. All COVID-19 patients admitted to seven ICUs in the Euregio-Meuse Rhine during the first pandemic wave were included. The 4C Mortality and SEIMC scores were selected as promising prognostic models from an external validation study. Five predictors could be estimated based on cohort size. TRIPOD guidelines were followed and logistic regression analyses with the linear predictor, APACHE II score, and country were performed. Bootstrapping with backward selection was applied to select variables for the final model. Additionally, shrinkage was performed. Model discrimination was displayed as optimism-corrected areas under the ROC curve and calibration by calibration slopes and plots. The mortality rate of the 551 included patients was 36%. Discrimination of the 4C Mortality and SEIMC scores increased from 0.70 to 0.74 and 0.70 to 0.73 and calibration plots improved compared to the original models after updating and extending. Mortality prediction can be improved after updating and extending of promising models.

Effect of heatwaves on mortality of Alzheimer's disease and other dementias among elderly aged 60 years and above in China, 2013–2020: a population-based study

BackgroundChina has the largest number of dementia patients in the world, posing a significant health and economic burden. Alzheimer's disease (AD) and other dementia patients face a higher risk of mortality during heatwaves, but relevant studies on this topic have been limited so far. MethodsThe study extracted data from the China Cause of Death Reporting System (CDRS) on deaths of AD and other dementia patients aged 60 years and above between 2013-2020. Using an individual-level, time-stratified, and case-crossover study design, the effects of heatwaves across nine scenarios on dementia mortality were quantified by conditional logistic regression combined with distributed lag non-linear model (DLNM). Additionally, the attributable fractions (AFs) of deaths due to heatwaves were calculated. FindingsA total of 399,036 death cases were reported caused by AD and other dementias during the study period. It was found that heatwaves significantly increased the risk of death among people with AD and other dementias. As the intensities and durations of the heatwaves increased, the lag0-7 cumulative odds ratios (CORs) of mortality increased progressively from 1·140 (95% CI: 1·118, 1·163) under the mildest heatwave to 1·459 (95% CI: 1·403, 1·518) under the most severe one, across nine heatwave scenarios examined. Additionally, under specific heatwave scenarios, sex and regions modified the mortality risk, but no significant age differences were observed. The AFs of AD and other dementia mortality due to milder heatwaves were lower compared to more severe heatwaves, ranging from 12·281% (95% CI: 10·555%, 14·015%) to 31·460% (95% CI: 28·724%, 34·124%). InterpretationThe study provided critical insights into the substantial increase in heatwave-related mortality among AD and other dementia patients during and after heatwave events. The results from our quantitative analyses will provide needed scientific evidence for policymakers and practitioners to develop relevant policies and guidelines to protect the health and well-beings of vulnerable populations in future in the context of both seasonal changes and long-term climate change.

Critical care unit bed availability and postoperative outcomes: a multinational cohort study.

Critical care beds are a limited resource, yet research indicates that recommendations for postoperative critical care admission based on patient-level risk stratification are not followed. It is unclear how prioritisation decisions are made in real-world settings and the effect of this prioritisation on outcomes. This was a prespecified analysis of an observational cohort study of adult patients undergoing inpatient surgery, conducted in 274 hospitals across the UK and Australasia during 2017. The primary outcome was postoperative morbidity at day 7. Logistic regression models were used to evaluate the relationship between critical care admission and patient and health system factors. The causal effect of critical care admission on outcome was estimated using variation in critical care occupancy as a natural experiment in an instrumental variable analysis. A total of 19,491 patients from 248 hospitals were eligible for analysis, of whom 2107 were directly admitted to critical care postoperatively. Postoperative morbidity occurred in 2829/19,491 (15%) patients. Increasing surgical risk was associated with critical care admission, as was increased availability of critical care beds (odds ratio (95%CI) 1.04 (1.01-1.06), p = 0.002) per available bed; however, the probability of admission varied significantly between hospitals (median odds ratio 3.05). There was no evidence of a difference in postoperative morbidity with critical care admission (odds ratio (95%CI) 0.91 (0.57-1.45), p = 0.710). Postoperative critical care admission is variable and related to bed availability. Statistical methods that adjust for unobserved confounding lowered the estimates of harm previously reported to have been associated with postoperative critical care admission. Our findings provide a rationale for a clinical trial which would evaluate any potential benefits for postoperative critical care admission for patients in whom there is no absolute indication for admission.

The Impact of Functionality and Psychological Outcome on Social Engagement 3-months after Intracerebral Hemorrhage

BackgroundAlthough it is well-known that intracerebral hemorrhage (ICH) is associated with physical and psychological morbidity, there is scant data on factors influencing social engagement after ICH. Understanding the relationship between functionality, psychological outcome and social engagement post-bleed may facilitate identification of patients at high risk for social isolation after ICH. MethodsPatients ≥18-years-old with non-traumatic ICH from January 2015-March 2023 were identified from the Neurological Emergencies Outcomes at NYU (NEON) registry. Data on discharge functionality were collected from the medical record. 3-months post-bleed, patients/their legally-authorized representatives (LARs) were contacted to complete Neuro-QoL social engagement, anxiety, depression, and sleep inventories. Patients were stratified by ability to participate in social roles and activities (good=T-score>50, poor=T-score≤50) and satisfaction with social roles and activities (high=T-score>50 and low=T-score≤50). Univariate comparisons were performed to evaluate the relationship between post-bleed social engagement and both functionality and psychological outcome using Pearson’s chi-square, Fisher’s Exact test, and Mann-Whitney U tests. Multivariate logistic regression was subsequently performed using variables that were significant on univariate analysis (p<0.05). ResultsThe social engagement inventories were completed for 55 patients with ICH; 29 (53%) by the patient alone, 14 (25%) by a LAR alone, and 12 (22%) by both patient and LAR. 15 patients (27%) had good ability to participate in social roles and activities and 10 patients (18%) had high satisfaction with social roles and activities. Social engagement was associated with both functionality and psychological outcome on univariate analysis, but on multivariate analysis, it was only related to functionality; post-bleed ability to participate in social roles and activities was associated with discharge home, discharge GCS score, discharge mRS score, and discharge NIHSS score (p<0.05) and post-bleed satisfaction with social roles and activities was related to discharge mRS score and discharge NIHSS score (p<0.05). ConclusionIn patients with nontraumatic ICH, social engagement post-bleed was related to discharge functionality, even when controlling for depression, anxiety, and sleep disturbance.

Diagnostic value of CT in patients with stable chronic obstructive pulmonary disease at high altitude: Observational study.

This research aims to explore the diagnostic value of computed tomography (CT) indicators in patients with stable chronic obstructive pulmonary disease (COPD) in a plateau of China, and to find out the correlation between CT indexes and lung function and symptoms. This study screened out 53 stable COPD patients and 53 healthy people through inclusion and exclusion criteria in Hongyuan county, Aba Prefecture, Sichuan Province, between July 2020 and December 2020, and then collected their baseline data, conducted lung function tests and chest CT scans, and collected COPD Assessment Test (CAT), modified Medical Research Council Dyspnea Scale (mMRC) scores. The CT indexes of the 2 groups were compared, binary logistic regression was used to analyze the influence of COPD, the receiver operating characteristic (ROC) curve was used to evaluate the diagnostic value of the CT indexes for COPD. The Spearman test was used to understand the correlation analysis between the CT indexes and lung function, symptom score, and the number of acute exacerbations. Multiple linear regression was used to analyze the influencing factors of lung function. The percentage of low-attenuation areas less than -950 Hounsfield units (%LAA-950; t = -4.387,P = 0), percentage of wall area (WA%; t = -4.501, P = 0), and thickness-diameter ratio (TDR; t = -4.779, P = 0) in the COPD group were higher than those in the normal group. ROC shows that: %LAA-950 (P = .047) and TDR (P = .034) were independent influence in COPD in the plateau. %LAA-950 combined with TDR (AUC = 0.757, P < .001) had the value of diagnosis of COPD in the plateau. All 3 indexes are negatively correlated with lung function, and positively correlated with the symptoms and the number of acute exacerbations. Multiple linear regression analysis showed that the main factors for decrease of ratio of measurement to prediction of forced expiratory volume to the first second (FEV1%) included %LAA-950 (OR = -0.449, P < .001) and WA% (OR = -0.516, P < .001). CT indexes have a certain diagnostic value in patients with stable COPD at high altitude.

Disparities in Treatment for Alcohol Use Disorder Among All of Us Participants.

The authors examined racial/ethnic and socioeconomic disparities in receiving treatment for alcohol use disorder (AUD). A retrospective cohort study was conducted that included adults (≥18 years) with AUD from the All of Us Controlled Tier database v7. Outcomes were lifetime receipt of FDA-approved medications (disulfiram, acamprosate, and naltrexone), psychotherapy (individual, family, and group-based session), and combination treatment (medication and psychotherapy). The study examined treatment receipt by race/ethnicity (non-Hispanic White, non-Hispanic Black, Hispanic, other), insurance (private, Medicare, Medicare and Medicaid, Medicaid, Veteran Affairs [VA], none), income (<$10K, $10-<$50K, $50-$100K, >$100K), and area deprivation index (ADI) quintiles. Multivariable logistic and multinomial logistic regressions were used to assess the association between patient characteristics and treatment receipt. The cohort consisted of 18,692 patients (mean age=57.1 years; 60.7% were male; 47.1% were non-Hispanic White). Almost 70% received no treatment, 11.4% received medication, 24.0% received psychotherapy, and 4.9% received combination treatment. In adjusted analysis, non-Hispanic Black (aOR=0.78, 95% CI=0.69-0.89) and Hispanic (aOR=0.75, 95% CI=0.64-0.88) individuals were less likely to receive medication than non-Hispanic White counterparts. There was no association between race/ethnicity and receipt of psychotherapy or combination treatment. Compared with private insurance, dual eligibility was associated with less use of medication, Medicare and Medicaid with less use of medication and combination treatment, and VA and no insurance with more use of psychotherapy and combination treatment. Higher income and lower ADI were positively associated with all treatment types. There are disparities in AUD treatment by race/ethnicity, socioeconomic status, and insurance. Systematic approaches are required to improve equitable access to effective treatment.

Prevalence and risk factors associated with undiagnosed hypertension among adults aged 15–49 years in India: insights from the National Family Health Survey (NFHS-5)

ObjectivesTo estimate the prevalence and identify the factors associated with undiagnosed hypertension in India. Study designA secondary data analysis using the National Family Health Survey (NFHS-5) covering the period 2019–2021. MethodsInformation on hypertension among individuals aged 15–49 years was extracted from the survey dataset. We estimated the prevalence of undiagnosed hypertension using physical measurements along with self-reported data from the survey. A log-binomial model with survey-adjusted Poisson regression was used to estimate the prevalence ratio between undiagnosed and diagnosed hypertension. Multinomial logistic regression analysis examined the factors associated with diagnosed hypertension (vs healthy) and undiagnosed hypertension (vs healthy). All the analyses were survey-weight adjusted and stratified by gender. ResultsThe survey-adjusted prevalence of undiagnosed hypertension was 8.75% (8.62%–8.87%) and was higher among males [13.56% (13.03%–14.12%)] than in females [8.14% (8.03%–8.25%)]. The proportion of individuals with undiagnosed hypertension among total hypertension was 44.99% (44.44%–45.55%) and was higher in males [65.94% (64.25%–67.60%)] than in females [42.18% (41.66%–42.71%)]. ConclusionsOur findings revealed that age, higher body mass index, no access to health care, and having no comorbidities were risk factors for undiagnosed hypertension. One in twelve people had undiagnosed hypertension, and of those with hypertension, one in two were undiagnosed, with males being disproportionately affected. Targeted public health interventions are crucial to improve hypertension screening, particularly among middle-aged and obese individuals without comorbidities.

Association of the Life's Essential 8 cardiovascular health score with periodontitis among US adults.

To investigate whether cardiovascular health (CVH) is associated with periodontitis. We used data from the 2009 to 2014 National Health and Nutrition Examination Survey. We quantified CVH using Life's Essential 8, which includes four health behaviours (diet, smoking, physical activity and sleep) and four health factors (body mass index, blood cholesterol, glucose and pressure). We categorized scores as low (0-49), moderate (50-79) and high (80-100). We calculated subscores of health behaviours and factors and categorized them as low, moderate and high. We used logistic regression to assess the association of CVH with periodontitis, adjusting for age, gender, race/ethnicity, education, poverty index, marital status and health insurance. We computed odds ratios (ORs) and 95% confidence intervals (CIs). This study included 9296 adults ≥30 years old. Multivariable-adjusted models showed that subjects with moderate (OR, 0.62; 95% CI: 0.52-0.74) or high (OR, 0.43; 95% CI: 0.33-0.57) CVH had significantly lower odds of periodontitis compared to those with low CVH. These results were consistent in the health behaviours model, but the estimates in the health factors model were not significant. Improving CVH may help prevent periodontitis. Longitudinal studies are needed to confirm our findings.

The dietary inflammatory index (DII®) and human papillomavirus infection: a cross-sectional study of US women

BackgroundDiet may influence susceptibility of human papillomavirus (HPV) infection by affecting inflammation and immunity. However, the association between HPV infection and the inflammatory potential of diet has not been investigated. The research aimed to examine the correlation between HPV status and the dietary inflammatory index (DII®).MethodsWe utilized data from the National Health and Nutrition Examination Survey (NHANES) 2003–2016 to investigate the correlation between DII and HPV status among 9,256 women aged 18–59 years. DII scores were calculated based on 24-hour dietary recall interviews. The association between HPV status and DII was analyzed using weighted logistic regression and restricted cubic spline (RCS).ResultsWomen with HPV infection exhibited higher DII scores than those without HPV infection. An increased likelihood of HPV infection was found to be significantly associated with higher DII scores (OR = 1.05, 95% CI: 1.01–1.09, P = 0.021), after full multivariate adjustment. Compared with the lowest tertile of DII scores, the ORs (95% CIs) for HPV infection were 1.20 (1.01, 1.42) and 1.27 (1.07, 1.51) for the second and third tertiles, respectively (P for trend = 0.006). RCS analysis showed a U-shaped relationship between DII and HPV infection, with a breakpoint identified at 0.13.ConclusionsOur findings suggest that a pro-inflammatory diet is associated with an increased likelihood of HPV infection among women in the United States. Dietary interventions to reduce inflammation may help prevent HPV infection and related diseases.

Iodine nutrition status of children 3-13 years of age in areas with high groundwater iodine content in China.

Adequate iodine status is crucial for children's health and normal development. However, there is a paucity of research on the iodine status of children from areas with high groundwater iodine content. To monitor the iodine status of children in Shandong, China (regions primarily characterized by high iodine concentrations in groundwater) and to describe the factors influencing children's iodine status. A cross-sectional study was conducted from 2013 to 2023 on 3,253 children aged 3-13 years. We collected drinking water, spot urine, and 24-hour urine samples from children to assess their iodine status (measuring drinking water iodine concentration (WIC), water iodine intake (WII), urine iodine concentration (UIC), 24-hour urine iodine excretion (24-h UIE), daily iodine intake (DII), etc.), and analyzed influencing factors. The median WIC for children was 183 (IQR: 70.2, 362) μg/L, and the median spot UIC was 428 (IQR: 194, 737) μg/L, surpassing the WHO cutoff (300 μg/L). Children at risk of iodine excess numbered 1750 (61.8%). Approximately 61% of iodine intake came from drinking water. Boys had significantly higher iodine intake than girls (P < 0.001). Children's age showed positive correlations with spot UIC, 24-h UIC, and 24-h UIE. There were no significant differences in 24-h UIC and 24-h UIE among children with different BMIs. The logistic regression model revealed that the risk of iodine excess was increased by boy gender, increment in age (OR = 1.05, 95% CI: 1.02, 1.08), and every 10 μg (OR = 1.04, 95% CI: 1.03, 1.04) or 50 μg (OR = 1.19, 95% CI: 1.16, 1.22) increment in WII. Children in areas with high groundwater iodine content are at a risk of iodine excess. As age increases, the risk of iodine excess in children rises, with boys at a higher risk than girls.

Multidimensional Healthcare Access Barriers to Prostate-Specific Antigen Testing: A Nation-Wide Panel Study in the United States From 2006 to 2020.

Rising metastatic prostate cancer incidence has renewed debate regarding benefits of prostate-specific antigen (PSA) screening. Identifying barriers to accessing screening for individuals at high risk of lethal prostate cancer may slow this rise. We examined associations of access barriers with receipt of PSA testing, stratified by sociodemographic factors. We pooled data from male respondents to Behavior Risk Factor Surveillance Systems (BRFSS) surveys from 2006 to 2020. Questions related to affordability (insurance, cost of visits) and accommodation (regular primary care provider (PCP), physician recommending a PSA test) were considered as individual-level barriers. For availability, we linked provider density from the 2012 Area Health Resource File and estimated driving times to closest health facility within Micropolitan and Metropolitan Statistical Area (MMSA) using Google Earth Engine. These measures were used to compute a spatial accessibility index. We fit survey-weighted, covariate-adjusted logistic regression models to estimate associations of barriers with receipt of PSA within the past 2 years and examined effect modification by sociodemographic factors. There were 185,643 participants, of whom 73% were White, 11% were Black, 4% were Asian, and 11% were Hispanic. Physician recommendation was the strongest predictor of having a PSA test (aOR: 14.5, 95% CI: 13.6, 15.6). Not having a regular PCP (aOR: 0.29, 95% CI: 0.27, 0.31), insurance (aOR: 0.64, 95% CI: 0.58, 0.71), and prohibitive cost of care (aOR: 0.82, 95% CI: 0.75, 0.90) were associated with lower PSA testing. Access barriers were stronger predictors of PSA testing for Asian and White participants compared to other groups (Phet < 0.004 for insurance and regular PCP) and for those with college education compared to those without (Phet < 0.05 for insurance, perceived unaffordability). Physician recommendation was the strongest predictor of receipt of PSA testing, regardless of sociodemographic grouping. Future studies should consider access barriers jointly and across sociodemographic strata.

Doxycycline as Post-Exposure Prophylaxis: Awareness, Beliefs, and Interest Among Patients with and at Risk for HIV.

Recent studies have demonstrated the efficacy of doxycycline as post-exposure prophylaxis (doxy-PEP) for sexually transmitted infection (STI) prevention, but little is known regarding patient beliefs and interest in doxy-PEP. We conducted a cross-sectional survey of adults (≥ 19 years) receiving care for HIV treatment (PWH) or prevention (pre-exposure prophylaxis, PrEP) between May-October 2023. The 32-question survey was organized into three parts: doxy-PEP awareness/beliefs/interest/concerns, sexual history, and demographics. Fishers Exact and Wilcoxon rank sum tests were used to compare responses between groups. Multivariate logistic regression identified predictive factors for doxy-PEP interest and concern(s). 166 participants completed the survey. Mean age was 43 years, 83% were male, 22% Black, and 13% Hispanic. Forty-one participants (25%) were on PrEP. Most respondents (75%) were unaware of doxy-PEP. Factors associated with doxy-PEP interest were respondents prescribed PrEP (aOR 2.67; 95% CI, 1.15-6.21) and belief of high risk for STI (aOR, 4.50; 95% CI, 2.24-9.07). Higher doxy-PEP concerns were associated with age ≤40 years (aOR, 3.10; 95% CI, 1.47-6.52), > high school education (aOR, 3.47; 95% CI, 1.64-7.33), and belief of high risk for STI (aOR, 2.58; 95% CI, 1.21-5.50). In this single-site cohort survey study, most respondents were unaware of doxy-PEP but expressed interest and low levels of overall concern. Clinicians should offer doxy-PEP access to all patients at high risk for STIs or requesting the treatment after shared decision-making discussions.

Reverse Total Shoulder Arthroplasty for Acute Proximal Humerus Fractures: Is Delay Associated With an Increased Rate of Reoperation?

To compare reoperation rates of acute versus delayed reverse total shoulder arthroplasty (RTSA) following a period of nonoperative treatment for proximal humerus fractures (PHFs). We also aimed to identify an optimal time interval from PHF to RTSA before the risk of reoperation significantly increased. . Database review. Ontario, Canada. Adults aged 50 years and older who sustained a PHF (OTA/AO 11A-C) between 2004 and 2019 were included. Exclusion criteria included polytrauma, open fractures, non-Ontario residents, invalid health insurance, and any operative treatment before RTSA. The primary outcome measure was reoperation within 2 years following RTSA. A risk-adjusted, restricted cubic spline was used to model the probability of reoperation according to the time elapsed between PHF and RTSA to identify a time point at which the risk of reoperation significantly increased. A multivariate logistics regression was used to identify predictors. In total, 891 patients (685 acute, 206 delayed) underwent RTSA for PHF. The acute cohort had a significantly lower reoperation rate (3.9%) compared with the delayed cohort (8.3%) (P = 0.02). The odds of reoperation increased with a delay to RTSA greater than 28 days and continued to rise until 100 days after fracture. Patients who underwent RTSA 28 days after PHF were found to have a significantly higher odds of reoperation by 2 years (P = 0.03). Among patients undergoing RTSA for acute PHFs, a delay to surgery greater than 28 days is associated with a greater odds of reoperation and may be useful when counseling patients.
