Human papillomavirus (HPV) is one of the most common sexually transmitted diseases and affects the quality of life (QoL) of individuals, necessitating interventions beyond physical treatments. The aim of this study is to determine the effectiveness of individual supportive counselling on the QoL in women with high-risk HPV.

This randomised clinical trial will include 80 women with HPV who will be selected from 2025 to 2026 in Babol, Iran. Following selection based on inclusion criteria, samples will be randomly allocated to intervention and control groups. Then, they will complete demographic–social questionnaires, QoL in HPV patients and general health questionnaires. Individuals in the intervention group will receive 4 weekly online supportive counselling sessions in addition to routine care. The control group will receive routine care. Both groups will complete the questionnaires again at 6 weeks and 4 months postbaseline. Data will be analysed using SPSS V.26 software and statistical tests including ², t-test and repeated measures analysis of variance, and regression models if necessary. A significance level of 5% will be used for the tests.

This study was approved by the Ethics Committee of Babol University of Medical Sciences (IR.MUBABOL.HRI.REC.1404.082). The trial will adhere to the ethical principles of the Declaration of Helsinki. Findings will be disseminated through publication in peer-reviewed journals and presentation at scientific conferences.

To assess nutrition-related knowledge, attitudes and practices among pregnant women, and identify socioeconomic and healthcare determinants.

A cross-sectional study on maternal nutrition during pregnancy.

Pregnant women attending primary healthcare centres in the south of Tehran from December 2022 to March 2024.

1535 pregnant women of all ages living in the south of Tehran (both Iranian and non-Iranian).

Pregnant women were systematically selected from primary healthcare centres. Data were collected via validated questionnaires and electronic health records. Statistical analyses included multivariate logistic regression (adjusted ORs (aORs) with 95% CIs) and generalised linear mixed models.

The findings revealed that a majority of pregnant women (83.3%; 95% CI 81.2% to 85.3%) exhibited low levels of nutritional knowledge (scores below 12), whereas 14% demonstrated moderate knowledge (scores between 12 and 17), and only 2.7% (95% CI 1.9% to 3.8%) possessed high nutritional knowledge (scores above 18). In terms of attitudes, 36.9% of respondents expressed positive views toward nutrition, with higher education significantly associated with positive attitudes (aOR=1.8; 95% CI 1.3 to 2.5, comparing higher vs lower education levels). Dietary variety was consistently reported by 65.4% of participants, while 8.5% lacked dietary variety. Statistically significant associations were observed between educational attainment, socioeconomic status and nutrition-related practices (p

As a cross-sectional study, these findings highlight substantial gaps in nutrition knowledge among pregnant women in Tehran, with socioeconomic status and education playing crucial roles in shaping dietary behaviours. Improving nutritional education through healthcare interventions is essential for enhancing maternal and fetal health outcomes.

Pregnancy is a period of physiological, psychological, hormonal and social changes. Mothers experience pregnancy anxiety during this period. One treatment used to reduce anxiety is Mandala colouring. In the present study, we intend to determine the effectiveness of Mandala colouring on anxiety and health status in the second trimester of pregnancy in pregnant women.

In this randomised controlled clinical trial study, 60 women with a gestational age of 14–28 weeks and 43–96 scores on the Vandenberg Pregnancy Anxiety Questionnaire will be selected by convenience sampling and will be assigned to intervention and control groups by block randomisation. Information will be collected using demographic and midwifery, Vandenberg Pregnancy Anxiety and General Health Questionnaires. For pregnant women in the intervention group, Mandala colouring will be performed for 6 days, with each session lasting 30 min. The control group will receive routine care. Analyses will be done using SPSS V.22 software.

This study was approved by the Ethics Committee of Babol University of Medical Sciences (IR.MUBABOL.REC.1402.129). The trial will adhere to the ethical principles of the Declaration of Helsinki. Findings will be disseminated through publication in peer-reviewed journals and presentation at scientific conferences.

With the growing older population, ensuring effective, accessible nutritional support within primary care as a first line of medical care is becoming increasingly important. Nutritional counselling is a promising approach to enhancing health outcomes and independence among older adults. However, a stronger evidence base is needed to assess its true effect and inform clinical decisions. Additionally, food insecurity remains an under-recognised issue in this population and is often overlooked in primary care settings. This highlights the need for simple, practical methods to identify those at risk. This study aimed to assess the effectiveness of nutritional intervention provided to older people and determine which nutrients may indicate food insecurity in primary care settings in Tehran.

The study will be conducted in two phases. The first phase is a prospective cohort study (single cohort). The second phase is a cross-sectional study on older people who refer to primary care settings affiliated with the Tehran University of Medical Sciences. In the first phase, the effectiveness of nutritional interventions – including counselling and diet – is evaluated based on anthropometric indicators (weight, waist circumference, calf circumference, arm circumference and waist-to-height ratio), blood pressure and scores from the Mini Nutritional Assessment, health-related quality of life, dietary intake and physical activity. Assessments will be evaluated prospectively at the beginning of the study, after 3 months, and at the end of the study. In the second phase of the cross-sectional study, by examining dietary intake and food insecurity, we will identify the specific nutrient or food group that serves as an indicator of food insecurity in the diet of older individuals. Intakes below 50% and 75% of the recommended daily allowance will be analysed. Through sensitivity and specificity analysis, we will identify which nutrient or food group is strongly associated with food insecurity in older people.

This study received approval from the Medical Ethics Committee of Tehran University of Medical Sciences, Tehran, Iran (IR.TUMS.MEDICINE.REC.1402.474). Study findings will be disseminated through peer-reviewed journal articles, presentations at national and international conferences and meetings with the Iranian Ministry of Health, facility and community stakeholders.

To evaluate temporal trends in the epidemiology of hip osteoarthritis (OA) in the USA from 1990 to 2019, with stratification by sex and geographic region.

Cross-sectional time-series analysis using secondary data from the Global Burden of Disease (GBD) study.

US population-based analysis, stratified by the four US Census Bureau regions: Northeast, Midwest, South and West.

De-identified, aggregate population-level data representing all adults in the USA from 1990 to 2019, drawn from the GBD database.

Age-standardised rates per 100 000 population for years lived with disability (YLDs), prevalence and incidence of hip OA. Outcomes were stratified by sex and region. Statistical significance was defined as p

Between 1990 and 2019, hip OA in the USA increased by 23.91% in YLDs, 24.67% in prevalence and 25.22% in incidence. In 2019, the mean YLDs were 28.30 in women versus 25.48 in men; prevalence was 49.55 versus 41.08; and incidence was 919.29 versus 818.10 (all p

There has been a substantial rise in the burden of hip OA in the USA over the past three decades. Women and residents of the Northeastern USA are disproportionately affected. These findings underscore the need for targeted public health strategies that account for geographic and sex-based disparities in hip OA burden.
