POPs

Mass shootings are a public health crisis and have become more frequent on U.S. university campuses over the past decade, with the number doubling since 2000. Due to this alarming trend, many institutions have developed response strategies for active shooting events. Yet, the extent to which these response strategies address the needs and minimize harm for students, faculty, and staff has not been evaluated critically after a campus mass shooting. Michigan State University (MSU) experienced a mass shooting on February 13, 2023...

SETTING: The Clinical Practice Research Datalink (CPRD) Gold database, which is linked to Hospital Episodes Statistics (HES) inpatient data, the HES Diagnostic Imaging Dataset (DID), Office for National Statistics mortality data and Index of Multiple Deprivation socio-economic status data...

Numerous studies have explored the effects of background music on reading comprehension, however, little is known about how native language (L1) lyrics and second language (L2) lyrics in background music influence reading comprehension performance for college students. The present study used a mixed experimental design to examine the effects of listening habits (between-participants variable: non-listeners or listeners), music type (between-participants variable: L1 (Mandarin) pop music, L2 (English) pop music or no music) and text language (within-participants variable: L1 or L2) on reading comprehension of college students in East China...

Background and aim: In the present study, we focus on the relationship between state authenticity - the experience of being true to oneself in a particular moment - and microdosing - a practice that implies repeatedly ingesting very small doses of psychedelics that do not reach the threshold for perceptual alterations. We propose that microdosing could increase state authenticity through influencing people's mood and the number and satisfaction with daily activities. Methods: We used self-assessments of state authenticity collected from 18 microdosers in the Netherlands across the period of 1 month for a total of 192 observations...

INTRODUCTION: The aim of this study was to assess the detrusor underactivity (DUA) prevalence of females with symptomatic anterior pelvic organ prolapse (POP) and to evaluate the relationship between DUA and POP stage. MATERIAL AND METHODS: This was a prospective study recruiting women with symptomatic anterior POP. Patients with symptomatic stage 2-4 POP quantification system (POP-Q) who underwent urodynamics (UD) between January 2018 and April 2021 were included...

Elucidating how damage impacts DNA dynamics is essential for understanding the mechanisms of damage recognition and repair. Many DNA lesions alter their propensities to form low-populated and short-lived conformational states. However, NMR methods to measure these dynamics require isotopic enrichment, which is difficult for damaged nucleotides. Here, we demonstrate the utility of the 1 H chemical exchange saturation transfer (CEST) NMR experiment in measuring the dynamics of oxidatively damaged 8-oxoguanine (8OG) in the mutagenic 8OGsyn ·Aanti mismatch...

Titanium dioxide (TiO2 ) is an important industrial chemical, and studies suggest its major production route - the chloride process could lead to the generation of unintentional dl-POPs. However, no relevant studies assessed the occurrence of dl-POPs associated with TiO2 production in the industrial zones, which is mostly due to the ultra-trace level distribution of these compounds in environmental compartments. The present study explored the novel possibility of utilising foraging animal-origin foods as sensitive indicators for addressing this challenge and generated a globally beneficial dataset by assessing the background levels of dl-POPs in the vicinity of a TiO2 production house in Southern India...

STUDY OBJECTIVE: To explore the effectiveness of transvaginal natural orifice transluminal endoscopic surgery extraperitoneal sacral hysteropexy (vNOTES-ESH) in women with symptomatic uterine prolapse over a two year follow-up. DESIGN: Retrospective cohort study. SETTING: Gynaecological minimally invasive centre. PATIENTS: Women undergoing sacral hysteropexy either by vNOTES (n=25) or laparoscopic (n=74) between November 2016 and December 2020...

Active metasurfaces with tunable subwavelength-scale nanoscatterers are promising platforms for high-performance spatial light modulators (SLMs). Among the tuning methods, phase-change materials (PCMs) are attractive because of their nonvolatile, threshold-driven, and drastic optical modulation, rendering zero-static power, crosstalk immunity, and compact pixels. However, current electrically controlled PCM-based metasurfaces are limited to global amplitude modulation, which is insufficient for SLMs. Here, an individual-pixel addressable, transmissive metasurface is experimentally demonstrated using the low-loss PCM Sb2 Se3 and doped silicon nanowire heaters...

The COVID-19 pandemic is having a profound impact on the health, social and economic well-being of people in Canada and around the world. To address vaccine disparity among vulnerable populations facing social-structural challenges, it is crucial to provide evidence-based information on the importance of completion of the recommended vaccination schedule. In this study, we investigated vaccination rates and variables as facilitators or barriers to COVID-19 vaccination among vulnerable populations living in Vancouver's inner-city residents...

Microplastics (MPs) and persistent pollutants (POPs) are new pollutants that are extensively studied worldwide. To fill the gaps that the degradation processes and mechanisms of polycyclic aromatic hydrocarbons (PAHs) on the surface of most MPs are still unclear, the photochemical transformation of benzo(a)anthracene (BaA) on polyvinyl chloride (PVC) MPs and polystyrene (PS) MPs in water were investigated and compared. The photolysis of BaA on the surface of PS in water proceeded easier than that on PVC within the 48 h irradiation period, with the pseudo-first-order rate constant of 0...

Halogenated aromatic pollutants (HAPs) including polychlorinated dibenzo-p-dioxins/furans (PCDD/Fs), polychlorinated biphenyls (PCBs), polybrominated dibenzo-p-dioxins/furans (PBDD/Fs), and polybrominated diphenyl ethers (PBDEs) exhibit diverse toxicities and bio-accumulation in animals, thereby imposing risks on human via animal-derived food (ADF) consumption. Here we examined these HAPs in routine ADFs from South China and observed that PBDEs and PCBs showed statistically higher concentrations than PCDD/Fs and PBDD/Fs...

CONTEXT: Obesity is a risk factor for coronavirus disease 2019 (COVID-19)-related outcomes; however, the mechanism remains unclear. OBJECTIVE: The objective of this analysis was to determine whether inflammation mediates the association between obesity and COVID-19 outcomes. DESIGN: The International Study of Inflammation in Covid-19 (ISIC): A Prospective Multi-Center Observational Study Examining the Role of Biomarkers of Inflammation in Predicting Covid-19 Related Outcomes in Hospitalized Patients...

INTRODUCTION: There is no evidence about the efficacy of self-care of vaginal pessary in women with symptomatic pelvic organ prolapse (POP). The aim of this systematic review and meta-analysis is to assess the adherence to pessary treatment among women who engage in self-management of their pessary. METHODS: We performed a systematic review and meta-analysis, according to PRISMA 2020 guidelines, and selected seven publications for inclusion in the analysis. RESULTS: Pooled continuation rate of self-cared vaginal pessary was the 76% (95%CI: 66-85%) with a I2 -test of 93...

OBJECTIVE: The study aimed to investigate treatment options for older women with pelvic organ prolapse (POP) and postoperative outcomes based on their long-term care (LTC) status. METHODS: We used the medical and LTC insurance claims databases of Tochigi Prefecture in Japan, covering 2014 to 2019. We included women 65 years and older with POP and evaluated their care status and treatment, excluding women with an observation period <6 months. Among women with a postsurgical interval ≥6 months, we compared care level changes and deaths within 6 months and complications within 1 month postoperatively between those with and without LTC using Fisher exact test...

To improve the adaptability of soft robots to the environment and achieve reliable attachment on various surfaces such as smooth and rough, this study draws inspiration from the collaborative attachment strategy of insects, cats, and other biological claw hooks and foot pads, and designs an actuator with a bionic claw hook-suction cup hybrid structure. The rigid biomimetic pop-up claw hook linkage mechanism is combined with a flexible suction cup of a "foot pad" to achieve a synergistic adhesion effect between claw hook locking and suction cup adhesion through the deformation control of a soft pneumatic actuator...

Snakes of the genus Boa are outstanding elements of the New World biota with a broad sociological influence on pop culture. Historically, several taxa have been recognized in the past 300 years, being mostly described in the early days of binomial nomenclature. As a rule, these taxa were recognized based on a suite of phenotypic characters mainly those from the external morphology. However, there is a huge disagreement with respect to the current taxonomy and available molecular phylogenies. In order to reconcile both lines of evidence, we investigate the phylogenetic reconstruction (using mitochondrial and nuclear genes) of the genus in parallel to the detailed study of some phenotypic systems from a geographically representative sample of the cis-Andean mainland Boa constrictor...

Given varied insurance acceptances and differing pay between insurances, our objective was to examine the number of California physicians enrolled in Medicare and Medicaid (Medi-Cal), stratified by specialty and graduation year. Medi-Cal and Medicare providers were extracted from publicly available databases (Centers for Medicare & Medicaid Services and California Health and Human Services) and were subsequently merged into one dataset using National Provider Identifier. From there, we stratified physicians by specialty and graduation year...

AIM: Laparoscopic lateral suspension is a novel approach for repairing anterior and apical pelvic organ prolapse (POP). According to integral theory, urinary symptoms and pelvic pain are believed to originate from suspensory ligaments. We aimed to investigate the objective and subjective outcomes of adding sacroterine plication to apical prolapse surgery. METHODS: Sixty patients with Grade 2 or higher symptomatic apical POP were included in the study. The study sample was categorized into two groups: Group 1 underwent lateral suspension and Group 2 underwent lateral suspension and sacroterine plication...

Proprioception, the sense of limb and body position, is required to produce accurate and precise movements. Proprioceptive sensory neurons transmit muscle length and tension information to the spinal cord. The function of excitatory neurons in the intermediate spinal cord, which receive this proprioceptive information, remains poorly understood. Using genetic labeling strategies and patch clamp techniques in acute spinal cord preparations in mice, we set out to uncover how two sets of spinal neurons, Clarke's column (CC) and Atoh1 -lineage neurons, respond to electrical activity and how their inputs are organized...
