Association of Contact Sexual Violence Victimization and Health in the U.S.

INTRODUCTION: Sexual violence victimization is related to negative impacts, including chronic health conditions. Less is known about possible confounders of this relationship. This study examines the association between lifetime experience of contact sexual violence (CSV) and health conditions by sex, controlling for demographics and other victimization. METHODS: Data are from the 2016/2017 National Intimate Partner and Sexual Violence Survey, a nationally representative study of English- or Spanish-speaking adults. Ten health conditions (e.g., HIV/AIDS) and four activity limitations (e.g., difficulty dressing) were examined related to CSV victimization. Logistic regression models examined the association between CSV victimization and health controlling for demographics and other victimization experiences. Analyses were conducted in 2022 to 2023. RESULTS: For women and men, many health conditions and activity limitations were significantly associated with CSV after controlling for demographics. Accounting for other victimization, female CSV victims had higher odds of experiencing difficulty sleeping (Adjusted Odds Ratio [AOR]=1.3); difficulty concentrating, remembering, or making decisions (AOR=1.7); and difficulty doing errands alone (AOR=1.4) than nonvictims. Male victims had higher odds than nonvictims of having HIV/AIDS (AOR=5.2); frequent headaches (AOR=1.5); chronic pain (AOR=1.5); difficulty sleeping (AOR=1.4); serious difficulty hearing (AOR=1.3); and difficulty concentrating, remembering, or making decisions (AOR=1.5). CONCLUSIONS: CSV had a negative impact on health, although other types of victimization appear to also have an impact, especially for women. Demographic characteristics also aid the understanding of the relationship between CSV and health. Efforts to prevent CSV and other forms of violence can be coupled with healthcare- and population-level approaches to improve long-term health.

Imaging GPCR Dimerization in Living Cells with Cucurbit[7]uril and Hemicyanine as a "Turn-On" Fluorescence Probe.

Although multiple forms of dimers have been described for GPCR, their dynamics and function are still controversially discussed field. Fluorescence microscopy allows GPCR to be imaged within their native context; however, a key challenge is to site-specifically incorporate reporter moieties that can produce high-quality signals upon formation of GPCR dimers. To this end, we propose a supramolecular sensor approach to detect agonist-induced dimer formation of µ-opioid receptors (µORs) at the surface of intact cells. With the macrocyclic host cucurbit[7]uril and its guest hemicyanine dye tethered to aptamer strands directed against the histidine residues, the sensing module is assembled by host-guest complexation once the histidine-tagged µORs dimerize and bring the discrete supramolecular units into close proximity. With the enhanced sensitivity attributed by the "turn-on" fluorescence emission and high specificity afforded by the intermolecular recognition, in situ visualization of dynamic GPCR dimerization was realized with high precision, thereby validating the supramolecular sensing entity as a sophisticated and versatile strategy to investigate GPCR dimers, which represent an obvious therapeutic target.

Rape and Sexual Coercion Related Pregnancy in the United States.

INTRODUCTION: Sexual violence is a major public health problem in the U.S. that is associated with numerous health impacts, including pregnancy. U.S. population-based estimates (2010-2012) found that three million women experienced a rape-related pregnancy during their lifetimes. The current study presents more recent estimates of rape and sexual coercion-related pregnancy and examines prevalence by demographic characteristics. METHODS: Data years 2016/2017 were pooled from the National Intimate Partner and Sexual Violence Survey, a random-digit-dial telephone survey of U.S. non-institutionalized adults 18 years and older. The analysis, conducted in 2023, examined lifetime experience of rape-related pregnancy, sexual coercion-related pregnancy, or both among U.S. women. Authors calculated prevalence estimates with 95% CIs and conducted pairwise chi-square tests (p-value<0.05) to describe experiences by current age, race/ethnicity, and region of residence among U.S. women overall and among victims. RESULTS: One in 20 women in the U.S., or over 5.9 million women, experienced a pregnancy from either rape, sexual coercion, or both during their lifetimes. Non-Hispanic Multiracial women experienced a higher prevalence of all three outcomes compared with non-Hispanic White, non-Hispanic Black, and Hispanic women. Among victims who experienced pregnancy from rape, 28% experienced a sexually transmitted disease, 66% were injured, and over 80% were fearful or concerned for their safety. CONCLUSIONS: Pregnancy as a consequence of rape or sexual coercion is experienced by an estimated six million U.S. women. Prevention efforts may include healthcare screenings to identify violence exposure and use of evidence-based prevention approaches to reduce sexual violence.

Whole-Genome Analysis of Termite-Derived Bacillus velezensis BV-10 and Its Application in King Grass Silage.

Bacillus velezensis (B. velezensis) is a cellulose-degrading strain that has the potential as an additive in fermented feed. B. velezensis BV-10 was isolated and screened from the termite gut. We sequenced the whole genome of this new source of B. velezensis to reveal its potential for use in cellulose degradation. Whole-genome sequencing of B. velezensis BV-10 showed that it has a circular chromosome of 3929792 bp containing 3873 coding genes with a GC content of 45.51% and many genes related to cellulose, hemicellulose, and lignin degradation. King grass silage was inoculated with B. velezensis BV-10 and mixed with other feed additives to assess the effect of B. velezensis BV-10 on the fermentation quality of silage. Six treatment groups were established: the control, B. velezensis BV-10, molasses, cellulase, B. velezensis BV-10 plus molasses, and B. velezensis BV-10 plus cellulase groups. After 30 days of silage-fermentation testing, B. velezensis BV-10 was found to rapidly reduce the silage pH value and significantly reduce the acid-detergent fiber (ADF) content (p < 0.05). The addition of B. velezensis BV-10 plus molasses and cellulase in fermented feed significantly reduced the silage neutral-detergent fiber and ADF content and promoted organic-acid accumulation (p < 0.05). The above results demonstrate that B. velezensis BV-10 promotes the fermentation quality of silage and that this effect is greater when other silage-fermentation additives are included. In conclusion, genes involved in cellulose degradation in B. velezensis BV-10 were identified by whole-genome sequencing and further experiments explored the effects of B. velezensis BV-10 and different feed additives on the fermentation quality of king grass silage, revealing the potential of Bacillus velezensis as a new silage additive.

LAIR1 drives glioma progression by nuclear focal adhesion kinase dependent expressions of cyclin D1 and immunosuppressive chemokines/cytokines.

Leukocyte-associated immunoglobulin-like receptor-1 (LAIR1), an immune receptor containing immunoreceptor tyrosine-based inhibiory motifs (ITIMs), has emerged as an attractive target for cancer therapy. However, the intrinsic function of LAIR1 in gliomas remains unclear. In this study, the poor prognosis of glioma patients and the malignant proliferation of glioma cells in vitro and in vivo were found to be closely correlated with LAIR1. LAIR1 facilitates focal adhesion kinase (FAK) nuclear localization, resulting in increased transcription of cyclin D1 and chemokines/cytokines (CCL5, TGFß2, and IL33). LAIR1 specifically supports in the immunosuppressive glioma microenvironment via CCL5-mediated microglia/macrophage polarization. SHP2Q510E (PTP domain mutant) or FAKNLM (non-nuclear localizing mutant) significantly reversed the LAIR1-induced growth enhancement in glioma cells. In addition, LAIR1Y251/281F (ITIMs mutant) and SHP2Q510E mutants significantly reduced FAK nuclear localization, as well as CCL5 and cyclin D1 expression. Further experiments revealed that the ITIMs of LAIR1 recruited SH2-containing phosphatase 2 (SHP2), which then interacted with FAK and induced FAK nuclear localization. This study uncovered a critical role for intrinsic LAIR1 in facilitating glioma malignant progression and demonstrated a requirement for LAIR1 and SHP2 to enhance FAK nuclear localization.

The Double-Leucine Motifs Affect Internalization, Stability, and Function of Organic Anion Transporting Polypeptide 1B1.

Organic anion transporting polypeptide 1B1 (OATP1B1) is specifically expressed at the basolateral membrane of human hepatocytes and plays important roles in the uptake of various endogenous and exogenous compounds including many drugs. The proper functioning of OATP1B1, hence, is essential for the bioavailability of various therapeutic agents and needs to be tightly regulated. Dileucine-based signals are involved in lysosomal targeting, internalization, and trans-Golgi network to endosome transporting of membrane proteins. In the current study, we analyzed the 3 intracellular and 13 transmembrane dileucine motifs (DLMs) within the sequence of OATP1B1. It was found that the simultaneous replacement of I332 and L333 with alanine resulted in a significantly reduced level of the mature form of OATP1B1. The cell surface expression of I332A/L333A could be partially rescued by MG132, as well as agents that prevent clathrin-dependent protein internalization, suggesting that this dileucine motif may be involved in the endocytosis of OATP1B1. On the other hand, I376/L377 and I642/L643, which are localized at transmembrane helices (TM) 8 and 12, respectively, are involved in the interaction of the transporter with its substrates. I642A/L643A exhibited a significantly decreased protein level compared to that of the wild-type, implying that the motif is important for maintaining the stability of OATP1B1 as well.

Cigarette smoking is linked to an increased risk of delirium following arthroplasty in patients suffering from osteoarthritic pain.

AIMS: Postoperative delirium (POD) is a common postoperative complication, and the potential relationship between cigarette smoking and POD is still unclear. The current study evaluated the relationship between preoperative smoking status in patients suffering from osteoarthritic pain and POD after total knee arthroplasty (TKA). METHODS: A total of 254 patients who had undergone unilateral TKA were enrolled between November 2021 and December 2022, with no gender limitation. Preoperatively, patients' visual analog scale (VAS) scores at rest and during movement, hospital anxiety and depression (HAD) scores, pain catastrophizing scale (PCS) scores and smoking status were collected. The primary outcome was the incidence of POD, which was evaluated by the confusion assessment method (CAM). RESULTS: A total of 188 patients had complete datasets for final analysis. POD was diagnosed in 41 of 188 patients (21.8%) who had complete data for analysis. The incidence of smoking was significantly higher in Group POD than in Group Non-POD (22 of 41 patients [54%] vs. 47 of 147 patients [32%], p < 0.05). The postoperative hospital stays were also longer than those of Group Non-POD (p < 0.001). Multiple logistic regression analysis showed that preoperative smoking (OR: 4.018, 95% CI: 1.158-13.947, p = 0.028) was a risk factor for the occurrence of POD in patients with TKA. The length of hospital stay was correlated with the occurrence of POD. CONCLUSIONS: Our findings suggest that patients who smoked preoperatively were at increased risk of developing POD following TKA.

Violent Victimization During Childhood in the United States: Associations With Revictimization and Health.

Childhood violence victimization is a serious adverse childhood experience with lasting health impacts. This study examined the prevalence and characteristics of five forms of childhood violence victimization and their association with revictimization and negative health conditions among adults. Data are from the 2010-2012 National Intimate Partner and Sexual Violence Survey. Age at first victimization and perpetrator sex were assessed; adjusted odds ratios assessed associations with revictimization and health. Ages 14-17 were the most common age at first victimization for most violence types; almost half of male (46.7%) and a quarter of female (27.0%) rape victims reported first victimization before age 10. Most victimization was associated with revictimization and negative health, controlling for adult victimization. Primary prevention of childhood violence may reduce later health risks.

A light-up fluorescence probe for wash-free analysis of Mu-opioid receptor and ligand-binding events.

With the aggravated burden of opioid use disorder spreading worldwide, demands for new forms of opioid receptor agonist/antagonist constitute immense research interest. The Mu-opioid receptor (MOR) is currently in the spotlight on account of its general involvement in opioid-induced antinociception, tolerance and dependence. MOR binding assay, however, is often complicated by difficulty in MOR separation and purification, as well as the tedious procedure in standard biolayer interferometry and surface plasmon resonance measurements. To this end, we present TPE2N as a light-up fluorescent probe for MOR, which exhibits satisfactory performance in both live cells and lysates. TPE2N was elaborately designed based on the synergistic effect of twisted intramolecular charge-transfer and aggregation-induced emission by incorporating a tetraphenylethene unit to emit strong fluorescence in a restrained environment upon binding with MOR through the naloxone pharmacore. The developed assay enabled high-throughput screening of a compound library, and successfully identified three ligands as lead compounds for further development.

Activation of angiotensin II type 2 receptor attenuates lung injury of collagen-induced arthritis by alleviating endothelial cell injury and promoting Ly6Clo monocyte transition.

As one of the most frequent extra-articular manifestations of rheumatoid arthritis (RA), interstitial lung disease (ILD) is still challenging due to unrevealed pathophysiological mechanism. To address this question, in the present study, we used the classical collagen-induced arthritis (CIA) mouse model to determine the related-immune mechanism of lung injury and possible pharmacological treatment for RA-ILD. At the peak of arthritis, we found CIA mice developed apparent lung injury, characterized by interstitial thickening, inflammatory cell infiltration, and lymphocyte follicle formation. Additionally, the endothelial injury occurred as the number of endothelial cells (ECs) and their CD31 expression decreased. Along with those, monocytes, predominantly Ly6Chi monocytes with pro-inflammatory phenotype, were also increased. While in the remission period of arthritis, ECs gradually increased with retrieved CD31 expression, leading to decreased infiltrating monocytes, but boosted Ly6Clo population. Ly6Clo monocytes were prone to locate around damaged ECs, promoted ECs proliferation and vascular tube formation, and lessened the expression of adhesion molecules. In addition, we evaluated angiotensin II type 2 receptor (Agtr2), which has been demonstrated to be protective against lung injury, could be beneficial in RA-ILD. We found elevated Agtr2 in CIA lung tissue, and activation of Agtr2, within its specific agonist C21, alleviated the pulmonary inflammation in vivo, reduced ECs injury, and promoted monocytes conversion from Ly6Chi to Ly6Clo monocytes in vitro. Our data reveal a potential pathological mechanism of RA-ILD that involves ECs damage and inflammatory monocytes infiltration and provide a potential drug target, Agtr2, for RA-ILD treatment.

Development and validation of a predictive risk model based on retinal geometry for an early assessment of diabetic retinopathy.

Aims: This study aimed to develop and validate a risk nomogram prediction model based on the retinal geometry of diabetic retinopathy (DR) in patients with type 2 diabetes mellitus (T2DM) and to investigate its clinical application value. Methods: In this study, we collected the clinical data of 410 patients with T2DM in the Second Affiliated Hospital of Chongqing Medical University between October 2020 and March 2022. Firstly, the patients were randomly divided into a development cohort and a validation cohort in a ratio of 7:3. Then, the modeling factors were selected using the least absolute shrinkage and selection operator (LASSO). Subsequently, a nomogram prediction model was built with these identified risk factors. Two other models were constructed with only retinal vascular traits or only clinical traits to confirm the performance advantage of this nomogram model. Finally, the model performances were assessed using the area under the receiver operating characteristic curve (AUC), calibration plot, and decision curve analysis (DCA). Results: Five predictive variables for DR among patients with T2DM were selected by LASSO regression from 33 variables, including fractal dimension, arterial tortuosity, venular caliber, duration of diabetes mellitus (DM), and insulin dosage (P< 0.05). A predictive nomogram model based on these selected clinical and retinal vascular factors presented good discrimination with an AUC of 0.909 in the training cohort and 0.876 in the validation cohort. By comparing the models, the retinal vascular parameters were proven to have a predictive value and could improve diagnostic sensitivity and specificity when combined with clinical characteristics. The calibration curve displayed high consistency between predicted and actual probability in both training and validation cohorts. The DCA demonstrated that this nomogram model led to net benefits in a wide range of threshold probability and could be adapted for clinical decision-making. Conclusion: This study presented a predictive nomogram that might facilitate the risk stratification and early detection of DR among patients with T2DM.

Effect of Perineural Dexamethasone with Ropivacaine in Continuous Serratus Anterior Plane Block for Postoperative Analgesia in Patients Undergoing Video-Assisted Thoracoscopic Surgery.

Purpose: The goal of this study was to evaluate the analgesic efficiency of dexamethasone with ropivacaine in continuous serratus anterior plane block (cSAPB) after video-assisted thoracoscopic surgery (VATS). Patients and Methods: Sixty-six patients who underwent VATS were randomized into two groups. All patients received cSAPB postoperatively, and patients in Group RD received 20 mL of 0.375% ropivacaine plus 0.1 mg/kg dexamethasone followed by an infusion of 0.2% ropivacaine plus 0.02 mg/kg/hour dexamethasone at a rate of 5 mL/h in patient-controlled analgesia (PCA) pump. Patients in Group R received 20 mL of 0.375% ropivacaine with normal saline followed by an infusion of 5 mL/h of 0.2% ropivacaine in PCA pump. Fifty milligrams of tramadol was given as rescue medication when the visual analog scale (VAS) score was ≥4 at rest. The primary outcomes were the sum of pressing number within 48 hours postoperatively and the time to the first patient-controlled bolus. The secondary outcomes were VAS scores, the incidence of rescue analgesia, wound infection and nausea/vomiting. Results: Within 48 hours postoperatively, the sum of pressing number was more in Group R (18.33 ± 3.149 vs 16.09 ± 3.292, P = 0.006), and the Log Rank Test showed a significant difference in time to the first patient-controlled bolus (P = 0.006). After the PCA infusion finished, there were significantly lower VAS scores in Group RD at 60 and 72 hours postoperatively (P < 0.001). Additionally, the incidence of rescue analgesia in Group R was significantly more than that in Group RD (P < 0.001). No incision infection was observed in any patient. Conclusion: The cSAPB with ropivacaine plus dexamethasone prolonged the duration of analgesia and motor blockade, reduced pain intensity and rescued analgesia requirements after the end of PCA infusion for patients undergoing VATS, which provide further improvement to continuous perineural block.

Association Between Wait Time of Central Venous Pressure Measurement and Outcomes in Critical Patients With Acute Kidney Injury: A Retrospective Cohort Study.

Background: Hemodynamic management is of paramount importance in patients with acute kidney injury (AKI). Central venous pressure (CVP) has been used to assess volume status. We intended to identify the optimal time window in which to obtain CVP to avoid the incidence of adverse outcomes in patients with AKI. Methods: The study was based on the Medical Information Mart for Intensive Care (MIMIC) IV database. The primary outcome was in-hospital mortality. Secondary outcomes included the number of ICU-free days and norepinephrine-free days at 28 days after ICU admission, and total fluid input and fluid balance during the first and second day. A time-dose-response relationship between wait time of CVP measurement and in-hospital mortality was implemented to find an inflection point for grouping, followed by propensity-score matching (PSM), which was used to compare the outcomes between the two groups. Results: Twenty Nine Thousand and Three Hundred Thirty Six patients with AKI were enrolled, and the risk of in-hospital mortality increased when the CVP acquisition time was >9 h in the Cox proportional hazards regression model. Compared with 8,071 patients (27.5%) who underwent CVP measurement within 9 h and were assigned to the early group, 21,265 patients (72.5%) who delayed or did not monitor CVP had a significantly higher in-hospital mortality in univariate and multivariate Cox regression analyses. After adjusting for potential confounders by PSM and adjusting for propensity score, pairwise algorithmic, overlap weight, and doubly robust analysis, the results were still stable. The HRs were 0.58-0.72, all p < 0.001. E-value analysis suggested robustness to unmeasured confounding. Conclusions: Among adults with AKI in ICU, increased CVP wait time was associated with a greater risk of in-hospital mortality. In addition, early CVP monitoring perhaps contributed to shortening the length of ICU stays and days of norepinephrine use, as well as better fluid management.

[Relationship of in-hospital mortality and using intra-aortic balloon pump with extracorporeal cardiopulmonary resuscitation in patients with cardiac arrest: a secondary analysis based on literature data].

OBJECTIVE: To assess the effect of intra-aortic balloon pump (IABP) on in-hospital mortality in patients with cardiac arrest undergoing extracorporeal cardiopulmonary resuscitation (ECPR). METHODS: A retrospective study was performed on 696 patients with intra-hospital cardiac arrest undergoing ECPR from Samsung Medical Center in Korea between January 2004 and December 2013. According to whether IABP was used, the patients were divided into ECPR group and ECPR+IABP group. Cox regression and propensity score matching (PSM) were used to examine the correlation between IABP usage and in-hospital mortality, and standardized mean difference (SMD) was used to check the degree of PSM. Survival analysis of in-hospital mortality was performed by the Kaplan-Meier method, and further analyzed by the Log-Rank test. Using the propensity score as weights, multiple regression model and inverse probability weighting (IPW) model were used for sensitivity analysis. In-hospital mortality, extracorporeal membrane oxygenation (ECMO) withdrawal success rate and neurological function prognosis were compared between the two groups. RESULTS: A total of 199 patients with cardiac arrest undergoing ECPR were included, including 120 males and 79 females, and the average age was (60.0±16.8) years. Thirty-one patients (15.6%) were treated with ECPR and IABP, and 168 patients (84.4%) only received ECPR. The total hospitalized mortality was 68.8% (137/199). The 1 : 1 nearest neighbor matching algorithm was performed with the 0.2 caliper value. The following variables were selected to generate propensity scores, including age, gender, race, marital status, insurance, admission type, service unit, heart rate, mean arterial pressure, respiratory rate, pulse oxygen saturation, white blood cell count. After the propensity score matching, 24 pairs of patients were successfully matched, with the average age of (63.0±12.8) years, including 31 males and 17 females. The in-hospital mortality was 72.6% (122/168) and 48.4% (15/31) in the ECPR group and the ECPR+IABP group [hazard ratio (HR) = 0.48, 95% confidence interval (95%CI) was 0.28-0.82, P = 0.007]. Multiple regression model, adjusted propensity score, PSM and IPW model showed that the in-hospital mortality in the ECPR+IABP group was significantly lower compared with the ECPR group (HR = 0.44, 0.50, 0.16 and 0.49, respectively, 95%CI were 0.24-0.79, 0.28-0.91, 0.06-0.39 and 0.31-0.77, all P < 0.05). The combined application of IABP could improve the ECMO withdrawal success rate [odds ratio (OR) = 8.95, 95%CI was 2.72-29.38, P < 0.001] and neurological prognosis (OR = 4.06, 95%CI was 1.33-12.40, P = 0.014) in adult cardiac arrest patients. CONCLUSIONS: In patients with cardiac arrest using ECPR, the combination of IABP was independently associated with lower in-hospital mortality, higher ECMO withdrawal success rate and better neurological prognosis.

Effect of major components of Tripterygium wilfordii Hook. f on the uptake function of organic anion transporting polypeptide 1B1.

Organic anion transporting polypeptide 1B1 (OATP1B1), which is specifically expressed at the basolateral membrane of human hepatocytes, is well recognized as the key determinant in the pharmacokinetics of a wide variety of drugs and considered as an important drug-drug interaction (DDI) site. Triptergium wilfordii Hook. f. (TWHF) is a traditional Chinese medicine that has a long history in treating diseases and more pharmacological effects were demonstrated recently. Components of TWHF mainly belong to the groups of alkaloids, diterpenoids, and triterpenoids. However, whether TWHF constituents are involved in herb-drug interaction (HDI) remains largely unknown. In the present study, we investigated the effect of four major components of TWHF, i.e. Triptolide (TPL), Celastrol (CL), and two alkaloids Wilforine (WFR) and Wilforgine (WFG) on the function of OATP1B1. It was found that co-incubation of these compounds greatly inhibited the uptake function of OATP1B1, with WFG (IC50 = 3.63 ± 0.61 µM) and WFR (IC50 = 3.91 ± 0.30 µM) showing higher inhibitory potency than TPL (IC50 = 184 ± 36 µM) and CL (IC50 = 448 ± 81 µM). Kinetic analysis revealed that co-incubation of WFG or WFR led to the reduction of both Km and Vmax of the DCF uptake. On the other hand, pre-incubation of WFG or WFR increased Km value of OATP1B1; while CL affected both Km and Vmax. In conclusion, co- and pre-incubation of the tested TWHF components inhibited OATP1B1 activity in different manners. Although co-incubation of WFG and WFR did not seem to directly compete with the substrates, pre-incubation of these alkaloids may alter the substrate-transporter interaction.

Sexual Violence Victimization of U.S. Males: Negative Health Conditions Associated with Rape and Being Made to Penetrate.

Sexual violence is a significant public health problem with long-term health implications. Previous investigations of male victimization have often relied on nongeneralizable samples to examine the health consequences of rape. Furthermore, made to penetrate (MTP) victimization has received very little attention as a specific form of sexual violence. Using data from the 2010 to 2012 National Intimate Partner and Sexual Violence Survey, we examined negative impacts (e.g., injury) and health conditions associated with experiences of rape and MTP among male victims in the United States. Results indicate that approximately 1 in 4 victims of rape-only and 1 in 12 victims of MTP-only reported physical injuries. An estimated 62.7% of rape-only victims and 59.8% of MTP-only victims reported at least one impact due to the perpetrator's violence. Rape victims were significantly more likely than non-rape victims to report 2 of 11 health conditions measured, while MTP victims had greater odds of reporting 6 of 11 health conditions measured compared to non-MTP victims. This article fills gaps in understanding the impacts of rape and MTP on male victims, and it is the only study to do so using a large, nationally representative sample. Sexual violence is linked to serious health effects but is also preventable. Screening for violence victimization and preventing male sexual violence before it happens are both important to reduce the risk for immediate and chronic health impacts.

Association between Sleep Duration and Hand Grip Strength among COPD Patients.

This study aimed to evaluate the association between night-time sleep duration and hand grip strength (HGS) among patients with chronic obstructive pulmonary disease (COPD). Participants aged ≥45 years were included in a nationally representative investigation clinical study in 2015. HGS was measured using dynamometers. The data on night-time sleep duration, sociodemographic information, and health-related variables were systematically collected. For analysis, sleep duration was categorized as <5 h, 5-7 h, 7 h, 7-9 h, and >9 h. Multivariable linear regression models were used to determine the possible association between the night-time sleep duration and HGS. Our results indicated that the shortest (<5 h) or the longest sleep duration (>9 h) was relevant to high risk of weaker HGS in females. In males, the shortest (<5 h) sleep duration was correlated to lower HGS. Thus, our findings clearly suggest that health care providers should focus on the potential influence of sleep duration on HGS among COPD patients.

Urea-to-Albumin Ratio and In-Hospital Mortality in Severe Pneumonia Patients.

OBJECTIVE: The urea-to-albumin ratio (UAR), as a new marker of the systemic inflammatory response, is associated with the mortality in pneumonia patients. However, the association between the UAR and in-hospital mortality in severe pneumonia (SP) has received little attention. METHODS: In this single-center retrospective cohort study, 212 SP patients in intensive care unit (ICU) from June 1, 2016, to June 1st, 2020, with baseline UAR were enrolled. The primary outcome was in-hospital mortality. The association of UAR with in-hospital mortality was assessed using a multivariable-adjusted Cox model. RESULTS: Of 212 patients, the median age was 73.0 (61.0, 82.8) years, 70.8% of patients were male, and the APACHE II score was 20.0 (16.0, 26.0). During the hospital period, 101 (47.6%) patients died. In-hospital mortality rates for the lower and higher UAR were 16 (27.6%) and 85 (55.2%), respectively (P < 0.001). Kaplan-Meier analysis revealed that survival rates were significantly different between the two groups (log rank = 13.71, P < 0.001). After adjusted for confounding factors, the higher UAR group was significantly associated with a hazard ratio (HR) for in-hospital mortality of 2.234 (95% confidence interval: 1.146-4.356, P=0.018). Besides, this pattern persisted in subgroup analyses considering sex (HR = 9.380; 95% CI: 2.248-39.138; P=0.002). CONCLUSIONS: Higher UAR levels at the commencement of admission to ICU may be independently associated with increased in-hospital mortality in SP patients.
