Background and objectivesTelehealth is the provision of healthcare services remotely via telecommunications technology. The implementation, clinical applications, and perceived effectiveness of telehealth among audiologists across the Arab region, particularly following its accelerated adoption due to the COVID-19 pandemic was investigated.
Materials and methodsA cross-sectional survey was conducted between April and June 2024 among 194 audiologists from multiple countries. A non-probability purposive sampling approach was implemented. The respondents were grouped into providers and non-providers of telehealth services. The questionnaire collected data on demographics, service delivery models, telehealth applications, training background, and perceived challenges. Descriptive and inferential analyses were performed to identify predictors of teleaudiology adoption.
Results46.9% of the sample reported providing telehealth services. Many of them (69.2%) indicated that they began offering telehealth services following the COVID-19 pandemic. Synchronous delivery was commonly utilised. Younger professionals and those employed in public institutions were more likely to engage in remote service delivery (p Conclusions
The audiologists’ reported perceptions and experiences indicate that teleaudiology remains limited in clinical diagnostic service delivery. Broader integration of teleaudiology practices may benefit from enhanced professional training, the development of standardised guidelines, and investment in technological infrastructure to support access to remote hearing healthcare.

BackgroundThe National Institute for Health and Care Research accepts applications for pilot and feasibility studies to their Research for Patient Benefit (RfPB) programme. There has been limited work describing the design practices of these applications and funding status. Knowing some of the qualities which may contribute towards a pilot or feasibility study application successfully gaining funding could help researchers improve the quality of their applications. Therefore, this study describes the protocol for a review looking at the characteristics of funded and non-funded external pilot trial applications. In particular, the primary objective is to describe the planned sample size and sample size justifications.
MethodsThe study will be conducted on 100 applications from Competition 31–37 with a randomised feasibility design, identified and given access to us by RfPB where the lead applicant has consented. We will screen these applications to identify the external pilot trials, first looking through the titles and then the full text. Following this, we will extract data on information such as medical area, study design, objective(s), sample size, sample size justification, and funding outcome stage one and two. Validation will be performed on 20% of the data extracted; discrepancies will be resolved by discussion or a third reviewer will decide if there is no consensus. We will use descriptive statistics to summarise quantitative data, and will analyse qualitative data using thematic analysis. Findings will be summarised through discussion with the project contributors to produce a reader-friendly guidance document.
DiscussionThis work will provide a more complete picture of RfPB external randomised pilot and feasibility trials. The findings will assist researchers when planning their pilot trials, and could help improve the quality of submitted applications.

BackgroundToday, community pharmacists’ responsibilities have expanded beyond the traditional role to include the management of minor ailments. Acute uncomplicated cystitis is one of the most prevalent medical conditions seen in primary healthcare and can be managed by community pharmacists (CPs).
ObjectivesTo evaluate community pharmacists’ history-taking practice when responding to patients with acute uncomplicated cystitis.
MethodsA cross-sectional simulated patient study was conducted from November 2022 to January 2023 in Khartoum locality targeting only pharmacists. Six trained female students played the simulation in which they pretended to have the clinical symptoms of acute uncomplicated cystitis and requested treatment for their condition. The Interactions during the simulation were documented immediately in a data collection form after each visit. Descriptive statistics were used to report the study outcomes.
ResultsA total of 238 community pharmacies were visited. The majority of the pharmacists were female. The mean of the number of questions that were asked by the pharmacists was 1 (SD = 1.6) questions. Among the studied pharmacists, 45.4% asked at least one question during patient assessment. The most asked question was if the patient has a fever, representing 61 (25.6%) CPs, followed by if there is vaginal discharge, representing 38 (16%) CPs. In response to scenario 47 (19.7%) CPs decided to refer the patient to a physician, and 45 (18.9%) of the CPs advised the patient to increase water intake.
ConclusionsThe study has revealed a poor history-taking practice towards acute uncomplicated cystitis during patient assessment. Further studies exploring pharmacists’ involvement in patient assessment are required. Strategies to improve community pharmacists’ practice, like continuing pharmacy education and providing a national guideline regarding patient assessment should be considered seriously.

BackgroundUnintended pregnancy among female sex workers (FSW) is a pressing reproductive health concern attributable to risky sexual behaviors, healthcare inequities and poor negotiation powers with male sex partners. However, evidence is scarce on the prevalence and determinants of unintended pregnancies among FSW, which is crucial for enhancing reproductive healthcare. This analysis aims to measure the prevalence of lifetime unintended pregnancies and their associated factors.
MethodsA cross-sectional study was conducted on 327 FSW in Jashore (a border belt district of Bangladesh) from September 2022 to March 2023. Participants were recruited through take-all sampling. Data were collected on the lifetime history of unintended pregnancies and other relevant variables through face-to-face interviews. Chi-square statistic was used to compare the characteristics of FSW reporting unintended pregnancies. To assess the net association of factors associated with unintended pregnancy, multiple logistic regression was applied.
ResultThe lifetime prevalence of unintended pregnancies was reported at 75.8% (95%CI: 71.0–80.1). Among those who reported unintended pregnancies, 37.1% (95%CI: 30.8–43.8) had no education, 39.9% (95%CI: 32.8–47.5) were 25–34 years old, 49.6% (95%CI: 39.3–59.9) were currently married and 62.9% (95%CI: 49.7–74.4) earned ≤10,000 BDT per month compared to those who did not report lifetime unintended pregnancies. The likelihood of unintended pregnancies was significantly higher among those who reported having sex with non-transactional male sex partners (AOR: 2.4, 95%CI: 1.1–5.3, p = 0.036) than those who never had sex with any non-transactional male sex partner. The likelihood was also higher among those who reported rape in their lifetime (AOR: 2.0, 95%CI: 1.0–3.8, p = 0.037) and who self-reported mental health problems (AOR: 2.1, 95%CI: 1.0–4.2, p = 0.045) within the past year, compared to their counterparts.
ConclusionThis study highlights the considerable prevalence and associated determinants of unintended pregnancies among FSW in Jashore. These determinants need to be considered to strengthen reproductive healthcare interventions and policies for FSW. Reproductive health of FSW cannot be improved unless these factors are addressed in the ongoing interventions.

The San Clemente Island fox (Urocyon littoralis clementae) is classified as a focal species for conservation management by the US Navy. They are considered vulnerable to a variety of vector-borne diseases due to their relatively high population density and low genetic diversity. During the dry (July–November) and wet (December–February) seasons of 2017–2018 we live-trapped 95 foxes and collected ectoparasites to test for the presence of pathogens. We found a significant difference in ectoparasite abundance on foxes between seasons, but no differences associated with sex or age. We found that foxes carried two species of flea (Echidnophaga gallinacea and Orchopeas howardi) and two tick species (Ixodes pacificus and Ixodes jellisoni). No evidence of Borrelia burgdorferi, Anaplasma phagocytophilum, or Borrelia miyamotoi bacteria were found. This paper is the first account of ectoparasite species identification, quantification, and pathogen testing for the San Clemente Island fox subspecies.by Khalid N. Alasim, Bandar M. Almohayya
This study investigated the construct validity and psychometric properties of the Arabic version of the Opinion Relative to the Integration of Students with Disabilities (ORI) scale. Data were collected from 400 general and special education teachers as well as university faculty members. Exploratory factor analyses revealed a four-factor structure explaining 51.37% of the variance. Confirmatory factor analysis of the 15-item model demonstrated acceptable fit after item refinement. Subscale Cronbach’s α values ranged from.60 to.78, reflecting acceptable but marginal internal consistency in some subscales, with a total α of.75 (Cronbach’s α = .60–.78; total α = .75). Reliability indicators were further evaluated using Cronbach’s alpha and the convergent validity was assessed using the Average Variance Extracted (AVE), and Pearson correlation. The findings indicate that university faculty members and teachers generally hold positive attitudes toward inclusion and confirm that the Arabic ORI is a reliable and valid tool for assessing such attitudes. These results provide evidence supporting the instrument’s use in research and policy initiatives aimed at promoting inclusive education across Arabic-speaking contexts.by Eslam T.

The concurrent use of herbal dietary supplements with prescription medications raises safety concerns due to the potential for clinically significant interactions. Matcha, a shade-grown green tea consumed as an ultra-fine powder, is rich in catechins that may inhibit the transport of P-glycoprotein (P-gp) substrates such as nadolol. This study investigated the effects of administering single and multiple doses of matcha on the pharmacokinetics of nadolol in an in vivo animal model. Male Sprague-Dawley rats (n = 32) were randomly assigned to four groups. Group 1 (negative control) was administered normal saline followed by a single oral dose of nadolol (10 mg/kg). Group 2 (matcha single-dose) was administered a single dose of matcha (250 mg/kg) whisked in normal saline, followed by nadolol (10 mg/kg) after 30 min. Group 3 (positive control) received itraconazole (50 mg/kg), followed by nadolol (10 mg/kg) after 30 min. Group 4 (matcha multiple-dose) received matcha (250 mg/kg daily for 21 days) before administering nadolol (10 mg/kg) on day 21. Blood samples were collected at 0, 0.33, 0.66, 1, 1.5, 2, 3, 4, 5, 8 and 24 h. Nadolol concentrations in plasma were measured by a validated high-performance liquid chromatography with fluorescence detection (HPLC-FL) method. Pharmacokinetic parameters were estimated using the PK solver add-in for Microsoft Excel. To ensure quality control, caffeine, a key marker compound of matcha green tea, was quantified using HPLC with ultraviolet detection (HPLC-UV). A single oral dosage of matcha (250 mg/kg) had no statistically significant effects on the pharmacokinetics of nadolol compared to the control group (p > .05). Although the multiple-dose matcha group showed an increase in Cmax (~45%), AUC0-t (~18%), and AUC0-∞ (~22%) for nadolol compared to the control group, these differences were not statistically significant (p > .05). In contrast, the t½ (h) of nadolol increased significantly from 4.0 ± 1.6 in the control group to 7.7 ± 4.2 (p = .039) in the matcha multiple-dose group. Itraconazole co-administration significantly increased systemic exposure (AUC) of nadolol (p = .009), confirming the validity of the animal model. Caffeine, a key marker compound in matcha tea, was quantified at 4.18 ± 0.44% w/w of dry matcha tea powder, equivalent to 41.8 ± 4.4 mg/g. This is the first study to explore the potential pharmacokinetic interaction between matcha tea and nadolol. Single and multiple oral doses of matcha green tea had negligible effects on most pharmacokinetic parameters of nadolol, except for an increased half-life in the multiple-dose group. Further research is needed to establish the clinical relevance of this interaction before definitive recommendations on the safety of matcha tea and nadolol coadministration can be made.by Liubov Arbeeva, Virginia B.

PurposeTo investigate the longitudinal relationships between serum biomarkers of joint metabolism, knee injury, and Knee Injury and Osteoarthritis Outcome Score (KOOS) using novel methodologies.
MethodsData were collected from military officers who enrolled as cadets between 2004–2009, with follow-up conducted between 2015–2017. Analyses included 234 officers who had no history of knee ligament/meniscal injury at the time of military academy matriculation, had serum biomarker measurements at matriculation and graduation, demographic data, and KOOS assessment at follow-up. Biomarkers included Collagen Type II (C2C) and Type I and II (C1,2C) collagenase-generated cleavage epitopes, C-terminal propeptide of Type II collagen (CPII), and C- and N-terminal telopeptides of type I collagen (CTX and NTX). Angle-based Joint and Individual Variation Explained (AJIVE) was used to determine demographic determinants of biomarker levels and individual modes of variation specific to biomarker levels at matriculation and graduation, stratified by sex.
ResultsWe confirmed known associations of joint metabolism biomarkers with age in both sexes and with smoking in males. Matriculation biomarker data in males suggested a protective biomarker profile characterized by high cartilage synthesis and low cleavage of type I and II collagen in association with healthy KOOS scores at follow-up. CPII measured at matriculation was negatively associated with incident injuries after adjustment for smoking status (p = 0.03, logistic regression), confirming results from AJIVE.
ConclusionThese exploratory analyses suggest that CPII alone, or in combination with other joint metabolism biomarkers, may help identify individual risk of knee injury.

Pneumococcal diseases caused by the human pathogenic bacterium Streptococcus pneumoniae are a major public health concern worldwide. In this study, we examined the pathogenicity of a clinical isolate of S. pneumoniae in the silk moth, Bombyx mori, larvae infection model. The whole genome sequencing of a clinical isolate of S. pneumoniae, Spn1 identified the presence of genes responsible for its virulence and antibiotic resistance. Spn1 infection of Bombyx larvae resulted in death within 24 h concomitant with an increase of phenoloxidase activity in the hemolymph. The bacterial load increased in the hemolymph within 9 h post-infection (p.i.) Ampicillin, ceftriaxone, tetracycline, imipenem, and erythromycin showed therapeutic effect in infected larvae, although the bacterial strain was resistant to erythromycin in vitro. The Bombyx homologs of mammalian TLR2 and TLR4, known as BmToll2 and BmToll9 (BmToll9−1 and BmToll9−2 isoforms), were upregulated in both the fat body and trachea. The antimicrobial peptide (AMP) genes, BmdefensinA and BmdefensinB, known to be regulated by the Toll signaling pathway, were significantly upregulated in both fat body and trachea after S. pneumoniae infection through hemolymph. Our data indicate that the Bombyx larvae can be a suitable infection model to study the pathogenicity of S. pneumoniae.by John Paul G. Kolcun, Ricky M. Ditzel Jr, Bradley L. Kolb, Ricardo B. V.

Study designRetrospective chart review.
ObjectiveDescribe safety/feasibility of implementing a novel clinical protocol for acute spinal cord injury (SCI) management.
Summary of background dataSpinal cord perfusion pressure (SCPP) has emerged as a promising target for the medical management of SCI patients. We report our early experience implementing a pragmatic SCPP-driven clinical protocol to supplant conventional mean arterial pressure (MAP) monitoring in the setting of acute SCI.
MethodsWe retrospectively reviewed charts of all SCI patients managed by our SCPP protocol since its adoption at two clinical sites as of 2/1/2023. The SCPP protocol was applied for all adult SCI patients of any injury grade, at any injury level with cord tissue involvement. Intrathecal pressure (ITP) was transduced by lumbar drain (LD). MAP was determined from invasive blood pressure recordings. SCPP was calculated as the difference between MAP and ITP, with an SCPP goal of >65mmHg.
ResultsEighteen patients have been treated since our SCPP protocol was adopted. Patients were predominately male (77.8%); the average age was 52.0 ± 16.2 years. Most injuries involved the cervical segment (72.2%), all of which were manifest clinically as central cord syndrome. The most common presenting injury severity was ASIA Impairment Scale D (44.4%).All patients underwent surgical intervention. There were no complications related to surgery, LD placement, or LD maintenance/ITP transduction during hospitalization. The SCPP protocol was continued for an average 5.2 ± 1.8 days. Eight patients required vasopressor support (44.4%) during that period, for an average 3.1 ± 2.1 days. Five patients underwent therapeutic CSF drainage to augment SCPP (27.8%). All patients maintained an average SCPP above goal for the duration of monitoring.
ConclusionsThis study further establishes the safety and feasibility of monitoring SCPP via LD measurement of ITP in acute SCI patients treated by clinical protocol at two clinical sites. There were no complications related to LD placement/maintenance or SCPP monitoring.

Pasteurella multocida is a pathogen that causes bovine respiratory disease, and the development of an effective vaccine is important for improving animal health. Live-attenuated vaccines induce a long-lasting immune response with minimal side effects. The objective of this study was to evaluate potential live vaccine candidates from three P. multocida mutants produced by separately disrupting the genes of filamentous hemagglutinin 2 (fhaB2), hydrogenase-1 operon (hyaE), and n-acylneuraminate-9-phosphatase (nanP) of a serogroup 3 strain (P1062, WT) by clinical testing and transcriptome analysis. Challenge with WT and the three mutants conferred protection against P. multocida, with less lung lesions (4.7–6.2%) compared to 22.4% in the sham group. Transcriptome analysis identified 807 differentially expressed protein-coding transcripts (DETs) in the blood and 6473 DETs in the liver compared to the sham, WT, and each of the mutants. In total, 15 and 64 differentially expressed microRNAs (DEmiRNAs) and 12 and 74 differentially expressed long non-coding RNAs (DElncRNAs) were identified in blood and liver, respectively. The DEmiRNAs were not significantly associated with the DETs within each comparison. DElncRNAs were associated with 12 and 170 DETs in blood and liver respectively. The greatest number of unique DETs were found between hyaE and sham groups in the liver, which agreed with the low colonization rate in the nares and palatine tonsils. For the DETs between sham and WT the under-enriched gene ontology terms in blood were all included in the liver for the DETs identified by WT vs. sham, nanP vs. sham, and hyaE vs. sham, and were related to the signaling pathway, stimulus, and sensory perceptions in biological processes with the molecular function of olfactory receptor activity. The number of identified DETs, decreased percentage of lung lesions, and colonization rates indicate that fhaB2 could be a promising vaccine candidate.by Anne C. M. Hermans, Julia Spaan, Marieke A.A.

IntroductionThis study focusses on the implementation of an integrated care pathway for women with SGA in their obstetric history that pursues value-based healthcare. This study aims to 1) Determine whether the integrated care pathway led to a reduction in the number of antenatal secondary care consultations, as an indicator of care efficacy, and 2) compare clinical outcomes for women with a history of SGA before and after implementation of the integrated care pathway.
MethodsRetrospective cohort study including data from pregnant women with a history of SGA within integrated maternity care organisation Annature, 2017–2020. Intervention was an integrated care pathway (2018). Pre- and post-intervention periods were compared assessing prenatal secondary care consultations, place and mode of delivery, and perinatal outcomes.
ResultsThe implementation of the care pathway for pregnant women with a history of SGA led to a reduction in mean number of prenatal secondary care consultations per pregnancy from 11 in 2017–5 in 2020, and fewer inductions of labour (78 (34.2%) vs 127 (26.8%), p = 0.045). Additionally, the number of births in primary care increased (35 (15.4%) vs 136 (28.8%), p Conclusion
The implementation of the care pathway for pregnant women with a history of SGA resulted in a reduction in prenatal secondary care consultations and fewer inductions of labour. Additionally, the number of births in primary care increased, with no significant adverse impact on neonatal outcomes in the post-intervention period compared to the pre-intervention period.

Acinetobacter baumannii is a growing threat characterized by worrisome antibiotic resistance. A deeper understanding of its resistance and virulence mechanisms is essential for developing new and effective treatments. Herein, we explore the role of the two-component (NtrB-NtrC) signal transduction system and two distinct glutamine synthetases (GlnA-1 and GlnA-2) in the nitrogen assimilation, stress response, and virulence in A. baumannii. Under nitrogen-limited conditions, the ntrC mutant showed significantly defective growth kinetics when ammonium was the sole source of nitrogen, whereas the glnA2 mutant exhibited an obvious growth defect when putrescine was the sole source of nitrogen. Moreover, under nitrogen limitation, the glnA1 and glnA2 expression increased by approximately twofold and ninefold, respectively. An enzymatic activity assay demonstrated that the A. baumannii extracellular glutamine synthetase activity is dependent on the type II secretion system (T2SS), confirming our previous results from a T2SS secretome study. Interestingly, this activity is also regulated by NtrC. An infection model using Galleria mellonella revealed that the ntrC mutant was significantly less virulent than both the wild-type and glnA2 mutant strains. These results provide new insights into the nitrogen regulatory network and its contribution to the A. baumannii virulence, underscoring NtrC as a promising target for future antimicrobial strategies.by Elizabeth Youens, Dan G.

Extreme conformation and reduced genetic diversity are recognised to lead to severely reduced health, welfare and longevity in certain dog breeds. There is growing interest in applying strategic crossbreeding to promote more moderate conformations and greater genetic diversity within currently problematic breeds. Crossbreeding could therefore lead to more rapid and effective improvements in welfare compared to current practices of within-breed selection. Deliberate crossbreeding between distinct different dog breeds is not a new concept; it was historically commonly used to create the current pure breeds, to increase genetic diversity and to bring new physical and/or temperament traits into existing breeds. However, a recent surge in the popularity of ‘designer crossbreeds’ (intentional crosses between established purebreds) has elicited fresh interest around the potential positives and negatives of crossbreeding practices. Further research on crossbred brachycephalic dogs is urgently required for a greater understanding of the motivators and barriers to their acquisition. An online survey explored factors that motivate dog breed choice and acquisition of both crossbreed and purebred dogs. In addition, the survey used both closed and open questioning to explore the UK public’s perceptions of crossbreeding, specifically (i) between a brachycephalic breed and a non-brachycephalic breed, and (ii) between two non-brachycephalic breeds. Free-text results were analysed using content analysis and subsequently quantified. Results from 4,899 participants identified that key motivators to acquire a brachycephalic crossbreed vs a brachycephalic purebred included perceptions of improved health, including the reduction in risk of breed and conformation-related disorders, and increased genetic diversity. However, the desire to acquire a purebred dog, or even a specific breed, remained a significant barrier to crossbreed acquisition, alongside concerns surrounding the ethics of crossbreeding. Other barriers included perceived negative changes to appearance and temperament of the offspring from crossbreeding. The current study identified a common set of acquisition decision-making factors across all ownership groups, including desiring a dog who the owner perceives to enjoy being loved and to enjoy physical affection, but further demonstrated that good health is of motivational low priority to some dog owners, particularly to owners of purebred brachycephalic dogs. The mix of positive and negative public perceptions and beliefs around crossbreeding and crossbreed dogs demonstrate the need for further research into the health, temperament and appearance of brachycephalic crossbreed dogs. The suitability of crossbreed dogs as an alternative to certain current purebred breeds with high risk of genetic or conformational disorders depends on both public desire and on evidence-based selection of suitable breeds to encourage crosses which maximise canine welfare.by Mary O’Keeffe, Nathan Skidmore, Arianna Bagnis, Przemysław Bąbel, Elżbieta A.

BackgroundPlacebo and nocebo effects significantly influence health outcomes, yet healthcare professionals receive limited training and guidance on their mechanisms and clinical application, creating a gap in education and practical understanding. Conducted within the European PANACEA Consortium, this study evaluated healthcare professionals’ knowledge, attitudes, and practices regarding placebo and nocebo effects, and assessed their needs in further education.
MethodsAn online cross-sectional survey among a European multi-country convenience sample of healthcare professionals collected data assessing participants’ knowledge, perceptions, and experiences regarding placebo and nocebo effects; their application and ethical considerations in clinical practice; and investigated educational needs and interest in further training. Quantitative data were analyzed using descriptive statistics, and thematic analysis was applied to the free-text responses.
ResultsAmongst 807 participants, 71.7% reported taking advantage of placebo effects in their practice, and over half of participants (55.8%) observing nocebo effects. Participants reported feeling somewhat confident (53.3%) in harnessing placebo effects with 47.5% feeling confident in preventing nocebo effects. The majority of respondents had not received formal training on placebo and nocebo effects, with most expressing an interest in further training in areas such as healthcare education, emphasizing communication skills to enhance placebo effects, and knowledge to recognize and reduce nocebo effects.
ConclusionsThere is a significant need for more comprehensive training on placebo and nocebo effects, particularly in early health professional education. These findings informed the development of educational resources and best practice recommendations developed as part of the outcomes from the PANACEA Consortium, improving the understanding and application of these effects among healthcare professionals across Europe.

Large Language Models (LLMs) have ushered in a transformative era in Natural Language Processing (NLP), reshaping research and extending NLP’s influence to other fields of study. However, there is little to no work examining the degree to which LLMs influence other research fields. This work empirically and systematically examines the influence and use of LLMs in fields beyond NLP. We curate 106 LLMs and analyze ∼148k papers citing LLMs to quantify their influence and reveal trends in their usage patterns. Our analysis reveals not only the increasing prevalence of LLMs in non-CS fields but also the disparities in their usage, with some fields utilizing them more frequently than others since 2018, notably Linguistics and Engineering together accounting for ∼45% of LLM citations. Our findings further indicate that most of these fields predominantly employ task-agnostic LLMs, proficient in zero or few-shot learning without requiring further fine-tuning, to address their domain-specific problems. This study sheds light on the cross-disciplinary impact of NLP through LLMs, providing a better understanding of the opportunities and challenges.by Wendy C. Hernández-Mazariegos, Felipe I.

Cockroaches are vectors of pathogens and parasites that pose public health risks, especially in developing countries with poor hygiene and inadequate infrastructure. This study aimed to identify the household factors associated with the occurrence of cockroaches and the helminth parasites they carry in a rural community. Data on household infrastructure, presence of domestic animals, and insect control methods were collected from 70 households in rural Guatemala. Cockroaches were captured using traps and manually. A Generalized Linear Mixed Model revealed that households with concrete roofs had 94% lower abundance of cockroaches than those with metal sheet roofs, while the presence of cats increased cockroach abundance by 2.6 times (p Moniliformis moniliformis, were identified, marking the first report of such parasites in household cockroaches in Guatemala. These results highlight the need for improved housing infrastructure and integrated pest management strategies to mitigate the risks associated with cockroach-borne parasites in vulnerable communities.by Jessica Liu, Sameer Pandya, Andreas Coppi, H.

BackgroundNear real-time electronic health record (EHR) data offers significant potential for secondary use in research, operations, and clinical care, yet challenges remain in ensuring data quality and stability. While prior studies have assessed retrospective EHR datasets, few have systematically examined the integrity of real-time data for research readiness.
MethodsWe developed an automated benchmarking pipeline to evaluate the stability and completeness of real-time EHR data from the Yale New Haven Health clinical data warehouse, transformed into the OMOP common data model. Twenty-nine weekly snapshots of the EHR collected from July to November 2024 and twenty-two daily snapshots collected from April to May 2025 were analyzed. Benchmarks focused on (1) clinical actions such as patient additions, deletions, and merges; (2) changes in demographic variables (date of birth, gender, race, ethnicity); and (3) stability of discharge information (time and status). A synthetic dataset derived from MIMIC-III was used to validate the benchmarking code prior to large-scale analyses.
ResultsBenchmarking revealed frequent updates due to clinical actions and demographic corrections across consecutive snapshots. Demographic changes were most frequently related to race and ethnicity, highlighting potential workflow and data entry inconsistencies. Discharge time and status values demonstrated instability for several days post-encounter, typically reaching a stable state within 4–7 days. These findings indicate that while near real-time EHR data provide valuable insights, the timing of data stabilization is critical for accurate secondary use.
ConclusionsThis study demonstrates the feasibility of automated benchmarking to assess the integrity of real-time EHR data and identify when such data become analysis ready. Our findings highlight key challenges for secondary use of dynamic clinical data and provide an automated framework that can be applied across health systems to support high-quality research, surveillance, and clinical trial readiness.

Cyperus amuricus (Cyperaceae) has exhibited potential anticancer activity against hepatocellular carcinoma (HCC), yet its molecular mechanisms and phytoconstituent interactions with oncogenic pathways remain underexplored. This study integrates in vitro cytotoxicity assays and molecular docking to evaluate the effects of C. amuricus fractionated extracts on HCC, focusing on PI3K/AKT/mTOR signaling axis. The ethyl acetate (EA) fraction selectively inhibited HepG2 cell proliferation (IC50 = 159.76 µg/mL) with minimal toxicity to normal fibroblasts. Apoptotic features—cell shrinkage, membrane blebbing, nuclear condensation, and DNA fragmentation—were confirmed through DAPI staining and gel electrophoresis. Western blot analysis revealed dose-dependent suppression of phosphorylated Akt and p70S6K, indicating pathway inhibition. Molecular docking identified strong binding affinities between Cyperaceae-derived compounds and PI3K/AKT/mTOR targets, with luteolin 7-O-β-D-glucuronopyranoside-6″-methyl ester blocked PI3K activation, vitexin bound AKT’s allosteric site, and digitoxin targeted mTOR’s ATP-binding pocket, showing comparable binding energies to reference ligands. These findings suggest C. amuricus as a promising candidate for natural product-based HCC therapy.by Abdullah M. Aldhaif, Mohammed A. Al-Garni, Ahmed A. Muyidi, Mohammed H. Makkawi
BackgroundClostridioides difficile infection (CDI) remains a major healthcare-associated infection with limited contemporary data from Saudi Arabia. This study evaluated CDI prevalence, risk factors, recurrence predictors, and treatment patterns in hospitalized patients at a tertiary teaching hospital.
MethodsRetrospective analysis of 1,054 hospitalized patients screened between March 2023 and February 2024. CDI was confirmed by positive toxin assay and/or nucleic acid amplification test (NAAT). Demographic, clinical, antibiotic, acid-suppressant, and treatment data were collected. Bivariate associations and multivariable logistic regression were used to identify predictors of recurrence.
ResultsCDI prevalence was 10.8% (114/1,054). Median age was 37 years (IQR 51.25); 32.5% had malignancy. Antibiotic exposure preceded CDI in 59.6% (meropenem 24.7%, ceftriaxone 16.5% of courses), and acid suppressants were used in 57.0% (omeprazole 92.3%). Recurrence occurred in 11.4% (13/114). On bivariate analysis, acid-suppressant use was significantly associated with recurrence (p = 0.041). In multivariable logistic regression, only metronidazole plus vancomycin combination therapy independently predicted recurrence (OR 11.29, 95% CI 1.13–112.42, p = 0.039). Trends were observed for malignancy (OR 2.94, p = 0.112) and acid-suppressant use (OR 1.85, p = 0.440), limited by the small number of recurrent events. Metronidazole monotherapy dominated treatment (64.8%).
ConclusionCDI prevalence reached 10.8% with an 11.4% recurrence rate. Acid-suppressant exposure and combination therapy were key recurrence signals, while metronidazole remains overused despite international guideline shifts. Enhanced antibiotic and acid-suppressant stewardship, alongside improved access to guideline-recommended therapies, are critical to reducing CDI burden in Saudi tertiary hospitals.
