To examine outcomes from respiratory pathogens containment strategies focused on international travellers.

We developed a compartmental model generalisable to respiratory infectious diseases, in which international travellers interact with each other and airline/airport workers during transit. We used SARS-CoV-2 Omicron surge data (basic reproduction number (R₀): 9.5) as a case example and performed sensitivity and scenario analyses, including varying the R₀ for different respiratory pathogens.

A US high-volume airport.

Simulated international travellers and airline/airport workers.

Projection of new and imported SARS-CoV-2 infections without intervention (No Intervention); pre-travel screening for travellers who intend to travel (intended travellers) with PCR (Pre-travel PCR); or antigen testing (Pre-travel Ag); mask-wearing guidance for travellers and workers (Mask-wearing); and a Combined strategy (Pre-travel PCR & Mask-wearing).

The number of new and imported respiratory disease infections over the 90-day simulation period.

Over the 90-day simulation, the number of infected travellers entering the USA would be: 1 155 580 (27.2% of 4.2 million (M) intended travellers) with No Intervention; 709 560/4.2M (16.7%) with Pre-travel PCR; 862 330/4.2M (20.3%) with Pre-travel Ag; 1033 820/4.2M (24.4%) with Mask-wearing; and 650 480/4.2M (15.3%) with Combined. The number of new infections among airline/airport workers would be: 25 670 (73.3% of 35 000 workers) with No Intervention; 25 260 (72.2%) in Pre-travel PCR; 25 590 (73.1%) in Pre-travel Ag; 24 630 (70.4%) in Mask-wearing; and 18 770 (53.6%) in Combined. In scenario analyses, the most impactful parameters were R₀ of the respiratory pathogen and population immunity level.

A Combined strategy of pre-travel PCR testing and mask-wearing would most effectively reduce respiratory infection among international travellers and airline/airport workers, but would still allow a substantial number of infections to enter the USA, especially when the pathogen is highly transmissible.

This study aimed to investigate the prevalence and associated factors of anaemia and its association with the academic performance of schoolchildren in Kandahar, Afghanistan.

This was a cross-sectional analytical study.

This was a school-based study conducted among 1866 schoolchildren aged 6–14 years in Kandahar city from September to December 2023. Haemoglobin concentration was measured using a portable HemoCue Hb 301 analyser, while the WHO age-adjusted cut-off for haemoglobin was used to classify anaemia. Data were analysed by using descriptive statistics, the ² test and multivariate logistic regression.

In this study, the mean age of the children was 9.1 years, 61.1% (1138/1866) were boys, 83.6% (1560/1866) had illiterate mothers, and 81.3% (1517/1866) belonged to poor families. Prevalence of anaemia among schoolchildren was 64.1% (1196/1866), while 20.8% (388/1866), 41.7% (778/1866), and 1.6% (30/1866) were suffering from mild, moderate and severe anaemia, respectively. Main associated factors of anaemia were being male (adjusted OR (AOR) 1.4, 95% CI 1.1 to 1.7, p=0.003), unemployed father (AOR 1.5, 95% CI 1.1 to 2.2, p=0.020), poor family (AOR 2.3, 95% CI 1.8 to 2.9, p

Prevalence of anaemia was very high and is a severe public health problem in schoolchildren of Kandahar. Based on the known consequences of anaemia on academic performance, the education and health authorities of Afghanistan should take serious steps to alleviate this problem. Periodic iron supplementation and deworming, as well as daily iron-rich mid-day meal programmes, should be started for both boys and girls in schools.

To examine demographic, behavioural and clinical determinants of self-rated health (SRH) among Iranian adults with hypertension (HTN), with a particular focus on the association between blood pressure (BP) control and perceived health.

National cross-sectional analysis of 15 predictors spanning demographic, lifestyle and clinical domains.

2021 Iranian STEPwise Approach to Non-communicable Disease Risk Factor Surveillance, a nationally representative survey.

A total of 8812 adults with HTN (mean age 56.97 years; 57% female). Controlled HTN was defined as systolic blood pressure

The primary outcome was SRH, measured on a standard EuroQol-Visual Analogue Scale (0–100).

Controlled HTN was independently associated with higher SRH scores (β=1.31, 95% CI 0.07 to 2.54). Positive predictors of SRH included male gender (β=4.34, 95% CI 3.38 to 5.31), higher wealth (richest vs poorest: β=5.52, 95% CI 4.06 to 6.97), sufficient physical activity (β=4.38, 95% CI 3.48 to 5.28), healthier diet (β=3.06, 95% CI 1.99 to 4.14) and complementary insurance coverage (β=2.50, 95% CI 0.63 to 4.37). Significant negative predictors included diabetes mellitus (β=–4.23, 95% CI –5.59 to –3.26), dyslipidaemia (β=–3.61, 95% CI –4.62 to –2.59), people who smoke (β=–4.21, 95% CI –5.64 to –2.78) and older age. Notably, antihypertensive medication use showed one of the strongest negative associations with SRH (monotherapy: β=–4.83; combination therapy: β=–5.28), likely reflecting underlying disease severity and treatment burden.

Better SRH among hypertensive adults was associated with controlled BP, healthier lifestyle patterns and higher socioeconomic status. Conversely, comorbidities, smoking, older age and antihypertensive treatment were linked to poorer perceived health. Integrating SRH screening into HTN management may help identify vulnerable individuals and inform targeted interventions addressing behavioural and socioeconomic determinants of health.

This study aimed to explore the strategies employed by nurses to manage workplace bullying.

Qualitative descriptive study.

The study was conducted in a hospital located in western Iran between 21 March and 22 September 2023.

A purposive sample of 14 nurses was selected.

Data collection was conducted through semistructured in-depth interviews. The collected data were analysed using a conventional content analysis approach. Lincoln and Guba’s (2004) criteria were employed to ensure data validity. The data management process was facilitated using MAXQDA software (2020 version).

Nurses’ experiences of workplace bullying were categorised into two themes: ‘constructive strategies’ and ‘non-constructive strategies’. These themes were further divided into categories: ‘seeking support’, ‘individual empowerment’, ‘avoidance’, ‘confrontation’ and ‘no reaction’. The subcategories encompassed specific strategies employed by nurses to manage workplace bullying.

The findings demonstrate that nurses use both constructive and non-constructive strategies to manage workplace bullying. Understanding nurses’ strategies for managing workplace bullying can assist managers in developing comprehensive intervention programmes to address these issues. It is crucial to provide nurses with training on using constructive strategies and avoiding non-constructive ones. Creating a healthy and supportive work environment and addressing the psychological and social aspects of bullying phenomena also play a vital role in reducing and managing bullying behaviours.

The Quadrivalent human papillomavirus (HPV) Vaccine Evaluation Study with Addition of the Nonavalent Vaccine Study (QUEST-ADVANCE) aims to provide insight into the long-term immunogenicity and effectiveness of one, two and three HPV vaccine doses. Here, we describe the protocol for QUEST-ADVANCE.

QUEST-ADVANCE is an observational cohort study including males and females who are unvaccinated or vaccinated with the quadrivalent or nonavalent HPV vaccine in British Columbia, Canada. Female participants who are unvaccinated or vaccinated with 1–3 doses of the quadrivalent or nonavalent HPV vaccine at 9–14 years of age will be recruited approximately 5 or 12 years postvaccination eligibility. Male participants who are unvaccinated or vaccinated with 1 or 2 doses of the nonavalent HPV vaccine at 9–14 years of age will be recruited at approximately 5 years postvaccination eligibility. The study involves a maximum of four visits over a period of 4–5 years for female participants, and two visits over a 12-month period for male participants. At each visit, self-collected swabs (cervico-vaginal or penile) and questionnaire data will be collected. In each study group, a subset of participants will be invited to participate in a substudy evaluating the long-term humoral immunogenicity of the HPV vaccine. Additional blood samples will be collected from participants who are part of the immunogenicity substudy. The total required sample size is 7180 individuals. The primary objectives are (1) to examine vaccine effectiveness in males and females against prevalent genital HPV infections for one, two and three doses of the HPV vaccine compared with unvaccinated participants and (2) to evaluate if there is non-inferior immunogenicity as indicated by type-specific antibody response of one dose of the HPV vaccine in 20–27-year-old females vaccinated at 9–14 years of age compared with historical data of three doses of the HPV vaccine females vaccinated at 16–26 years of age up to 12 years postvaccination.

QUEST-ADVANCE was approved by the Research Ethics Board of the University of British Columbia/Children’s and Women’s Health Centre of British Columbia (H20-02111). Individual electronic informed consent or assent will be obtained from each participant before any study-specific procedures are undertaken. Results will be published in an international peer-reviewed journal and on the study website.

Child-to-parent violence (CPV) has received limited attention in scientific literature, but due to a recent increase in reported cases, it has become a subject of investigation. The reliability and validity of the Child-to-Parent Violence Questionnaire (CPV-Q), in separate mother and father versions, have not yet been studied in Iran. This study aimed to assess the psychometric properties of the Persian CPV-Q.

This research employed a cross-sectional design to evaluate the Persian CPV-Q’s psychometric properties. The process included translation (using backward-forward method), face validity (via impact score calculation), content validity (using content validity ratio (CVR) and content validity index (CVI)), construct validity (through exploratory and confirmatory factor analyses (CFA)) and reliability assessment (via test–retest, coefficient α, coefficient and intraclass correlation coefficient (ICC)).

The study was conducted at the Faculties of Tabriz University of Medical Sciences.

A total of 500 qualified students from Tabriz University of Medical Sciences were recruited using cluster random sampling. These participants completed the Persian CPV-Q.

Face validity was confirmed, with impact scores exceeding 1.5 for all items. Content validity was strong, with CVR=0.92 and CVI=0.89. Exploratory factor analysis revealed four factors related to violence frequency and two factors regarding reasons for violence, consistent with the original questionnaire, covering 19 and 8 items, respectively. Total variance explained was 0.30 and 0.39 for the mother’s version and 0.33 and 0.43 for the father’s version in frequency and reason sections. The Kaiser-Meyer-Olkin test confirmed sample adequacy (

The Persian CPV-Q demonstrates adequate validity and reliability for assessing the prevalence and causes of CPV in Iranian society.
