Background: In Yemen, dengue fever (DF) is a widespread, locally endemic infectious disease, with high morbidity and mortality which mainly affects impoverished regions. Thus, this study aims to evaluate the knowledge, attitudes, and behaviors of the Shabwah community in Yemen regarding DF characteristics and prevention. Methods: The present study is a cross-sectional community-based study conducted in Shabwah Governorate, Yemen, between June 2021 and November 2021. Simple random sampling was used to select the sample (n = 370), and a validated closed-ended questionnaire was used to collect data. Results: In total, 370 individuals participated in this study; most respondents were female (N = 247, 66.8%), and more than half (N = 214, 57.8%) were younger than age 30. More than 50% of the population had completed a primary or secondary school, while approximately 33.03% of them were illiterate. Furthermore, more than half (53.5%) of the population had good knowledge of DF, while most of those educated at a university level (64.1%) had good attitude toward DF. Most of the population (68.4%) had good practice toward DF. Moreover, participants with a university level education, followed by those who completed secondary school, had significantly higher knowledge and practice scores than primary school and illiteracy (P = 0.05). Conclusion: The results of the study indicate that the residents of Yemen’s Shabwah Governorate are well-informed about the symptoms and signs of DF, have a positive attitude toward the disease, and employ appropriate preventive measures. Health education via various media should be mandated to increase community awareness and dispel misconceptions about DF.

Dengue fever (DF) is now a major concern for world public health. Despite the government's reactionary measures, dengue incidences in Yemen are on the

Knee osteoarthritis (OA) is a prevalent condition influenced by various biochemical, anatomical, and lifestyle factors. Vitamin D deficiency has been implicated in OA, but its role in disease severity and associated symptoms remains unclear. We aimed to investigate the prevalence of vitamin D deficiency in knee OA patients and its relationship with inflammatory markers and clinical symptoms. This retrospective study analyzed 986 patients with knee OA over a 3.5-year period. Vitamin D levels, ESR, and platelet counts were assessed, along with demographic and clinical data. Statistical analyses were conducted to explore associations. This study involved 986 patients with knee OA, majority of them (85% ) were female with mean age 52.95 ± 12.44 years. More than half of patients 59.7% had unilateral knee OA and 40.3% had bilateral knee OA. The mean value of Vitamin D3 was 25.35 ± 14.125. Vitamin D deficiency was observed in 70.9% of patients, with moderate deficiency being most prevalent (36.94%). No significant association was found between vitamin D levels and inflammatory markers. However, a strong association was observed between vitamin D deficiency and symptoms like polyarthralgia (p < .05)., Bilateral OA was associated with higher vitamin D deficiency levels compared to unilateral OA (P < .001). OA more prevalence among female .As well as, vitamin D deficiency is highly prevalent in knee OA patients and its severity associated with Bilateral OA and polyarthralgia but not with inflammatory markers. Future research should focus on the long-term impact of vitamin D supplementation and the molecular mechanisms underlying these disparities.

Background Cholera is a potentially life-threatening diarrheal disease if left untreated, transmitted via contaminated water or food, and linked mainly to poor sanitation. Yemen is facing a public health crisis with an increasing number of cases in 2024, underscoring the importance of improving awareness and the need for education to enhance prevention and management. Methods This observational cross-sectional study was conducted in July 2024. The data were collected via a self-administered online questionnaire. Inferential analysis included independent t-tests for comparing two groups and one-way ANOVA for multiple groups, with a statistical significance threshold of p<0.05. Results The study surveyed 412 Yemeni medical students, predominantly male (65.5%) and single (86.7%), with a mean age of 22.48±2.6 years. The mean knowledge score was 7.35±2.36, and significant knowledge gaps in recognizing the range of severity of the disease, risk factors, complications, and vaccine awareness exist. The mean attitude score was 11.45±2.13 out of 15, with 70% showing a positive attitude. The practices score was poor, with a mean of 4.32±2.18 out of 9, with low adherence to preventive measures such as washing and peeling fresh fruits and vegetables (<30%). Our analysis showed significant associations, with age positively correlating with knowledge (r=0.262; p<0.001) and attitudes (r=0.17; p<0.001), while females scored higher in practices (p=0.002). Academic year significantly influenced knowledge (p<0.001) and attitudes (p=0.003), with sixth-year students scoring the highest. Conclusion While the Yemeni medical students demonstrated moderate knowledge and a generally positive attitude toward cholera, significant gaps in preventive practices were noted. Addressing these gaps through targeted educational programs on disease prevention, transmission, and management is essential to strengthen students' preparedness and improve public health outcomes.

Juvenile dermatomyositis (JDM) is a rare systemic autoimmune vasculopathy primarily affecting children. It is characterized by muscular weakness and distinctive skin findings. This report describes the case of a two-year-old Yemeni girl from a resource-limited setting who presented with prolonged fever and later developed classic JDM symptoms, including malar rash, skin nodules, calcifications, and lower limb muscle weakness. Despite the unavailability of advanced diagnostic tools, the diagnosis was made based on clinical findings, elevated inflammatory markers, and muscle enzyme levels. Management included oral prednisolone, resulting in significant clinical improvement. This case highlights the challenges of diagnosing and managing atypical JDM presentations in resource-constrained areas while emphasizing the importance of clinical vigilance and multidisciplinary care. It also underscores the need for increasing awareness and better diagnostic access in low-resource settings. To our knowledge, this is the first reported case of JDM in Yemen.
