Background/Objectives: This study was conducted to determine the effect of a Health Belief Model–based education program implemented in Family Health Centers on women’s cervical cancer knowledge and their attitudes and beliefs toward HPV vaccination. Methods: This quasi-experimental pretest–posttest control group study was conducted between March and May 2026 at the Tuşba Training Family Health Center in Van, eastern Türkiye. The study included 150 women aged 18–49 years who had adolescent daughters aged 10–18 years. Data were collected using the Descriptive Information Form, the Cervical Cancer Knowledge Scale, and the Carolina HPV Immunization Attitudes and Beliefs Scale. The intervention group received a structured education program based on the Health Belief Model focusing on cervical cancer, HPV infection, and HPV vaccination. Descriptive statistics, chi-square tests, independent samples t-tests, paired samples t-tests, and mixed-design analysis of variance (ANOVA) were used for data analysis. Results: Following the educational intervention, cervical cancer knowledge scores increased from 2.13 ± 0.79 to 7.24 ± 0.84 in the intervention group, whereas no significant change was observed in the control group (p < 0.001). Total CHIAS scores increased from 24.32 ± 5.30 to 41.23 ± 2.51, accompanied by significant improvements in HPV vaccination attitudes and beliefs (p < 0.001). Significant Group × Time interaction effects were observed for cervical cancer knowledge, total CHIAS scores, and all CHIAS subdimensions (p < 0.001). Conclusions: The findings indicated that the Health Belief Model–based education program was associated with improved knowledge about cervical cancer and HPV and with more favorable attitudes and beliefs toward HPV vaccination. Structured educational programs implemented in primary healthcare settings may support the promotion of preventive health behaviors.

Objective:This study aimed toevaluateknowledge and attitudes regarding organ donation and the associated factorsamong individuals attending the Family Medicine Outpatient Clinic of Van Yüzüncü Yıl University.Methods: A cross-sectional study was conducted with 533 participants. Data were collected through face-to-face questionnaires.The questionnaire included nine sociodemographic items and nineteen multiple-choice questions plus one open-ended question on organ donation attitudes.Associations between organ donation attitudes and related variables were analyzed usingPearson’s chi-square test, Linear-by-Linear Association, and Fisher’s Exact Test where appropriate.Results:A total of 76.2% of participants considered organ donation religiously appropriate, and this group showed significantly higher donation intention (p < 0.001). Donation willingness was higher among urban residentsthan amongrural participants (p = 0.005). Significant associations were found betweendonation-related attitudes and trust in donors, perceived religious appropriateness, and information-related factors. Participants reportingchronic health problemsdiffered significantly across age groups.Moreover, 77.1% emphasized the importance of receiving information in their native language, indicating that language barriers may influence organ donation awareness.Conclusion:Attitudes toward organ donation are shapedmainlyby religious perceptions, information sources,place of residence, and language-related needs.Inadequate public information, language barriers, and limited access to reliable sources remain key obstacles to improving donation rates.

Blood samples collected in primary care may be transported to central laboratories, creating variable intervals between collection, processing and analysis. This study evaluated the effects of delayed analysis and storage temperature on routine biochemical and haematological test results under controlled laboratory conditions, with relevance to specimen handling and transport in primary care. This prospective, controlled, repeated-measures laboratory study included 32 healthy volunteers (16 women and 16 men) at Van Yüzüncü Yıl University Dursun Odabaş Medical Centre, Türkiye. Serum and ethylenediaminetetraacetic acid whole-blood specimens were stored at room temperature (18–24 °C) or 4 °C. Twenty-seven biochemical and 26 complete blood count parameters were measured at a common baseline and after 4, 8 and 24 h. Time effects were assessed separately for each storage condition using Friedman tests, followed by Wilcoxon signed-rank tests with Holm adjustment. Storage conditions were compared at each follow-up time using paired Wilcoxon signed-rank tests. Benjamini-Hochberg false discovery rate correction was applied to multiple testing. Statistical analyses were performed using Python and the SciPy scientific computing library. Delayed analysis produced time-dependent changes in several biochemical and haematological parameters, with the magnitude of change varying according to storage condition. At 24 h at room temperature, haematocrit increased by 7.61%, mean corpuscular volume by 7.51% and red cell distribution width-standard deviation by 15.95%, whereas mean corpuscular haemoglobin concentration decreased by 7.11%. Corresponding changes in these erythrocyte-related indices were substantially smaller at 4 °C. Platelet indices changed under both conditions, with mean platelet volume increasing by 4.85% at room temperature and 6.85% at 4 °C, and platelet large cell ratio increasing by 17.34% and 23.72%, respectively. Among biochemical analytes, triglycerides increased by 14.75% at room temperature and 11.55% at 4 °C, while total iron-binding capacity increased by 11.15% and 8.86%, respectively. Delayed analysis and storage temperature were associated with measurable changes in several routine biochemical and haematological test results. Refrigerated storage generally reduced time-dependent changes in several haematological parameters compared with room-temperature storage, although changes were also observed at 4 °C. These findings highlight the importance of considering both storage temperature and analysis delay when handling specimens collected in primary care. The statistically significant changes observed should not be interpreted as formal analytical or clinical stability thresholds.

Amaç: Bu araştırmanın amacı, çok tehlikeli ve az tehlikeli işyerlerinde çalışan işçilerin ilk yardım ve temel yaşam desteği bilgi düzeyini etkileyen faktörleri değerlendirmektir. Yöntem: Araştırma, Van Yüzüncü Yıl Üniversitesi Aile Hekimliği Anabilim Dalı'nda Ocak 2020 ile Ekim 2020 tarihleri arasında yapılmıştır. 18-65 yaş arası, çok tehlikeli veya daha az tehlikeli bir işte sigortalı olan ve çalışmaya katılmayı kabul eden kişiler çalışma dahil edildi. İki bölümden oluşan bir anket uygulandı, ilk bölüm sosyodemografik ve mesleki özellikleri topladı, ikinci bölüm ilk yardım ve temel yaşam desteği (20 madde) ile ilgili bilgi düzeyini değerlendirdi. Bulgular: Araştırma bulgularına göre orta yaş (p<0.001) ve evlilerin oranı (p<0.001), ilkokul mezunu (p<0.001) ve erkeklerin (p<0.001) oranları çok tehlikeli işyeri çalışanlarında daha yüksekti. Çok tehlikeli iş yerlerinde ilk yardım ve temel yaşam desteği eğitimi alma sıklığı daha düşüktü (p=0.011). En az doğru cevaplanan üç soru, gözdeki metal cisim perforasyonuna müdahale (%32.6), ilk yardımın 'ABC'si (%34.2) ve çocuklarda temel yaşam desteği (%38.8) idi. Yaş ile bilgi düzeyi arasında ilişki yoktu (r=-0.057, p=0.209). Eğitim düzeyi yüksek olanlarda (p<0.001) ve ilk yardım ve temel yaşam desteği eğitimi alanlarda (p<0.001) ilk yardım ve temel yaşam desteği bilgi düzeyi daha yüksekti. Çok tehlikeli iş yerlerinde çalışan işçilerde eğitim alma sıklığının (p=0.011) ve bilgi düzeyinin (p<0.001) anlamlı derecede düşük olduğu belirlendi. Sonuç: Eğitim düzeyi yüksek olanlar, ilk yardım ve temel yaşam desteği eğitimi alanlar ve daha az tehlikeli iş yerlerinde çalışanlar ilk yardım ve temel yaşam desteği bilgi düzeyleri daha yüksektir. Bunlar, özellikle çok tehlikeli işyerlerinde tekrarlanan eğitim ihtiyacına işaret etmektedir. Purpose: The aim of this research was to evaluate factors affecting the knowledge level of first aid & basic life support (FA&BLS) among workers employed in ‘very hazardous’ and ‘less hazardous’ workplaces. Methods: This research was carried out in Van Yüzüncü Yıl University, Department of Family Medicine, between January 2020 and October 2020. Persons between the ages of 18–65 who were insured in a very hazardous or less hazardous job and agreed to participate in the study were included. A two-part questionnaire was applied, the first part collected sociodemographic and occupational characteristics, the second part evaluated the level of knowledge concerning FA&BLS (20 items). Results: Median age (p<0.001) and proportions of males (p<0.001), married people (p<0.001) and primary school graduates (p<0.001) were higher in very hazardous workplace workers. The frequency of having received FA&BLS was lower in very hazardous workplaces (p=0.011). The level of knowledge FA&BLS was higher in those with higher education (p<0.001) and those who received FA&BLS training (p<0.001). It was determined that the frequency of having received training (p=0.011) and the level of knowledge (p<0.001) were significantly lower among workers employed in very hazardous workplaces. Conclusions: The level of knowledge of FA&BLS is higher in those with a higher education level, those with FA&BLS training and those who work in less hazardous workplaces. These indicate the need for repeated training particularly in very hazardous workplaces.

Background: Province-level evidence on the implementation of population-based HPV screening in eastern Türkiye remains limited. This study aimed to describe screening activity relative to the programme-defined target population, HPV test positivity, recorded genotype patterns, histopathological diagnoses, and available follow-up information within the cervical cancer screening programme in Van Province. Methods: This retrospective, record-based programme evaluation used aggregated programme data from 2022 through the first two months of 2026 and individual-level records for HPV-positive women from 2023–2025. Annual screening activity ratios were calculated using programme-defined target populations. Age and recorded genotype distributions were described among HPV-positive women. Histopathological diagnoses and referral-related information were reported as available programme records because individual-level linkage and complete pathway denominators were unavailable. Temporal change in programme HPV test positivity was assessed using the Cochran-Armitage trend test. Results: Across the study periods, annual screening counts summed to 94,123 records, with 2,078 HPV-positive results (2.21%). The screening activity ratio increased from 17.1% in 2022 to 95.5% in 2024 and decreased to 67.9% in 2025. Observed programme HPV test positivity declined from 3.17% in 2022 to 1.80% in 2025 (p for trend < 0.001). Among 1,810 HPV-positive women with individual-level data, the mean age was 44.5 years. HPV16 was the most frequently recorded specific genotype (36.4%), HPV16 and/or HPV18 was recorded in 43.8%, and at least one recorded oncogenic genotype targeted by the nine-valent vaccine was identified in 55.4%. Multiple specifically identified HPV genotypes were recorded in 16.5%. Programme records contained 394 histopathological diagnoses during 2023–2025, including three invasive cervical cancer records. Available follow-up data did not permit calculation of referral, hospital attendance, colposcopy, biopsy, or treatment completion rates. Conclusions: HPV screening activity in Van varied substantially across years, while observed programme test positivity declined during 2022–2025; this decline should not be interpreted as evidence of reduced population HPV prevalence. Recorded genotype findings were dominated by HPV16, but variation in type-specific reporting limits temporal interpretation. Improved standardization of genotype reporting and individual-level linkage across screening, referral, diagnosis, histopathology, and treatment would strengthen programme monitoring.
