Background: Chronic kidney disease (CKD) affects over 35.5 million US adults. Serum α1-acid glycoprotein (α1-AGP), an acute-phase protein, exhibits anti-inflammatory properties in animal models, but its association with CKD in younger women remains underexplored. This study investigated the relationship between serum α1-AGP and CKD risk in US women aged 20–49 years. Methods: This nationally representative cross-sectional study used data on female adults in the US aged 20–49 years from the National Health and Nutrition Examination Survey 2015–2018 cycles. 2,137 individuals were included in the study after excluding individuals without serum α1-AGP, urine albumin, and creatinine data. Multivariate logistic regression models evaluated the association between serum α1-AGP and CKD. Moreover, we performed stratified and interaction analyses to see if the relationship was stable in different subgroups. Results: Among 2,137 participants (mean age 34.6 years, mean eGFR 111.7 mL/min/1.73 m²), CKD prevalence was 8.8% (n=188). Higher serum α1-AGP levels were associated with lower CKD risk in the fully adjusted model (OR 0.37, 95% CI 0.16–0.84, P = 0.017), with a dose-response trend across quartiles (P = 0.041). The association was stronger in women aged 40–49 years (OR 0.20, 95% CI 0.05–0.76) and Mexican Americans (OR 0.07, 95% CI 0.01–0.56), though interaction terms were not significant (P > 0.05). Conclusions: Higher serum α1-AGP levels are associated with lower CKD prevalence in young women, suggesting a protective role. Longitudinal studies are needed to confirm causality and explore α1-AGP as a biomarker for CKD risk stratification.

This article presents a mathematical model designed to simulate the impact of targeted interventions aimed at preventing HIV transmission among female sex workers (FSWs) and their clients, while also analyzing their effects on the health of the general population. The compartmental model distinguishes between high-risk populations (FSWs and their clients) and low-risk populations (sexually active men and women in the general population), and links prevention efforts in high-risk groups to the evolution of the epidemic in the low-risk population. The fundamental properties of the model, such as the positivity of solutions and the boundedness of the system, have been verified, and the basic reproduction number R₀ has been calculated. Finally, the stability of the model was studied using Varga’s theorem and the Lyapunov method. Simulation results show that targeted prevention among FSWs and their clients reduces HIV incidence in the general population. This framework provides a valuable tool for guiding policymakers in the design of effective strategies to combat the epidemic, especially relevant in the context of suspension of USAID funding.

Background: Vitamin D plays an important role in the development of bone health and possibly non-communicable diseases. Arab countries had made their own national studies to assess serum vitamin D level among women, yet in Egypt there is no national survey done. The aim of the current study was to identify risk factors affecting vitamin D level among Egyptian females during the child-bearing period. Subjects and methods: A total of 100 healthy adult females in their childbearing period who were attending a Family Medicine Center were included in our study. The age of the included women ranged from 19 to 49 years old with a mean age of 34 (SD 8.47) years. The majority of participants had deficiency (43%) and insufficiency (13%) of vitamin D level. Results: Unemployed women were more likely to have vitamin D deficiency than employed women (P<0.05). Participants who were exposed to sun ˃30 minutes/day were more likely to have sufficient vitamin D level (P<0.05). All participants who consume fish ≥3 times/week had sufficient vitamin D level. Therefore, there was a statistically significance association between a number of consuming fish/week and vitamin D3 level groups. Also, there was statistically significant association between number of consumed milk cups/day and vitamin D3 level groups. All participants who drink 2 cups of milk have sufficient vitamin D level. No statistically significance association was found between using multivitamins and vitamin D3 level groups. Conclusion: Unemployment, low fish consumption and infrequent sun exposure were significant risk factors for vitamin D deficiency. Future research on the role of multivitamins supplements in improving vitamin D nutrition is warranted.

Respiratory virus co-infections have been suggested to happen frequently and exacerbate patients’ conditions, but little is known about the detailed rates and the combinations of viruses during the COVID-19 pandemic period. A total of 255 symptomatic patients who underwent multiplex PCR tests were analyzed, and it was found that 6 (6/255=2.4%) patients were infected with multiple viruses. The patients ranged in age from 1 to 38 years, and one female patient was pregnant. Of the 6 patients, 4 had fever, and 5 had human rhinovirus/enterovirus and another virus. These data suggested that the rate of respiratory virus co-infection was low, and the combination of SAS-CoV-2 and other viruses was rare even during the COVID-19 pandemic.

A regular menstrual cycle is important to maintain a woman’s fertility. This cycle has been linked to optimal function of the thyroid gland in the production of its hormones. Disturbance of thyroid gland functions could result to female infertility due to changes in menstrual patterns. Aim of this research was to determine the correlation between thyroid gland functions and menstrual patterns amongst infertile and fertile women attending a tertiary care hospital in North-Central Nigeria. This comparative, cross-sectional study recruited 106 women who visited the hospital's Gynecology Clinic and Family Planning Clinic. 53 of the 106 patients were women with a history suggestive of either primary or secondary infertility and the remaining 53 women with no history of infertility served as the control. A well-structured questionnaire was used to obtain data on the patients’ menstrual patterns. Anthropometric data were measured and obtained. Collected blood samples were analyzed using Enzyme-Linked Immunosorbent Assay (ELISA) technique to determine the serum levels of thyroid hormones. All obtained data was analyzed, and the level of significance was set at p<0.05, at a 95% confidence interval. 33 patients had menstrual anomalies (78.8% infertile women; 21.2% fertile women who served as control, p=0.012). The incidence of menstrual anomalies in the infertile women group and control group was 7.5% versus 0.0% for amenorrhea; 20.8% versus 5.7% for menorrhagia; 9.4% versus 7.5% for oligomenorrhea; 7.5% versus 0.0% for hypomenorrhea; nil polymenorrhea for both groups; and 50.9% versus 86.8% for normal menstrual patterns. Ten (9.43%) patients were diagnosed with thyroid dysfunctions (80% in infertile group; 20% in control group, p=0.046). Six (18.2%) out of 33 women with menstrual anomalies were diagnosed with thyroid dysfunction. Five (83.3%) out of these 6 women with both menstrual anomalies and diagnosed thyroid dysfunction were infertile while only one (16.7%) was fertile. Thyroid gland dysfunction correlates strongly with abnormal menstrual patterns, which implies that it is vital to evaluate thyroid hormone levels in blood serum in the course of treating menstrual irregularities and female infertility. Early detection of thyroid dysfunction is important in achieving a positive treatment outcome for female infertility.

Addressing adolescent and sexual reproductive healthcare is essential to providing young patients with the resources they need to navigate and empower themselves with. However, there is limited data about how often this occurs. Several studies have previously indicated that there is a large gap in accessing this gap in low-income neighborhoods. Our study aims to identify the establishment of gynecologic care among adolescent cisgender women and elucidate potential reasons for seeking or not seeking out care. We approached women in the pediatric emergency room that matched the inclusion criteria set out. Qualitative surveys were conducted until thematic saturation was reached and a cross-section study design was employed. Interviews were analyzed through modified ground theory. The study was conducted at the pediatric emergency department at University Hospital located in Newark, NJ. In 2018 estimates, the Newark population consists of 47.0% Black and 39.2% Hispanic or Latinos. Semi-structured interviews were conducted with 27 cisgendered, English-speaking females between ages 18 to 25 presenting to the pediatric emergency room who may or may not have previously established primary care with a gynecologist. Transcriptions were analyzed using modified grounded theory and themes were identified using inductive coding of patient interviews.

To report a case of a major branch retinal vein occlusion (BRVO) in the superotemporal region with superior macular involvement and a review of its natural history. This is a retrospective case presentation of a 49-year-old African Caribbean female patient presented to Accident and Emergency with unilateral persistent acute history of reduced central vision of left eye for 10 days with no other associated symptoms. Treatment options included using scatter (pan-retinal) laser photocoagulation followed by intravitreal injections as the area of non-perfusion is >5-disc area. It is warranted to understand the risk factors associated with BRVO and to develop appropriate treatment and follow-up plans.

Background: The sacroiliac joint (SIJ) plays a crucial role in transmitting axial loads and maintaining pelvic stability. Sacroiliac joint arthropathy (SIJA) accounts for 10%–30% of low back pain cases but remains underrecognized due to overlapping pain referral patterns and nonspecific imaging findings. Diagnosis relies primarily on characteristic pain distribution and provocative maneuvers, with image-guided intra-articular block serving as the diagnostic gold standard. This study aimed to characterize the clinical profile of block-confirmed SIJA, emphasizing referral pain distribution, triggering position, and provocative test responses. Methods: A cross-sectional study was conducted on 98 patients with diagnostic block–confirmed SIJA at Siloam Hospital Lippo Village, Indonesia. Demographic data, referral pain sites, sitting duration, and results of FABER, compression, and distraction tests were analyzed descriptively. Results: The mean age was 52.07 ± 14.17 years, with 72.4% females. Referral pain most frequently involved the lower back (28.6%) and thigh (28.6%), with occasional extension to the groin (8.2%) or calf (4.1%). Over half of patients (55.1%) reported sitting more than six hours daily. Pain was predominantly triggered during sit-to-stand transitions (85.7%) and while sitting (74.5%). SIJ tenderness (98.0%) and FABER positivity (75.5%) were most consistent. Conclusion: The dominant referral pain in SIJA involves the lower back and posterior thigh. Sit-to-stand transition is the most frequent triggering position, while FABER testing demonstrates the highest diagnostic yield among provocative maneuvers. These consistent patterns may serve as practical clinical indicators to improve diagnostic accuracy in suspected SIJ-related pain.

Introduction: Stroke remains one of the leading causes of death and disability worldwide, with ischemic stroke accounting for most cases. Structural vascular factors such as carotid artery tortuosity have gained attention as potential markers of vascular aging and cerebrovascular risk. The carotid tortuosity index (CTI), defined as the ratio of actual vessel length to the straight-line distance between two fixed points, provides a quantitative measure of arterial curvature. A CTI value of ≥1.2 indicates pathological tortuosity. Although noninvasive modalities such as CTA and MRA are frequently used, digital subtraction angiography (DSA) remains the gold standard for evaluating vessel geometry due to its higher spatial precision. This study aimed to determine the association of age, sex, and hypertension with CTI measured by DSA. Methods: A cross-sectional study was conducted from November to December 2025 at the Neurointervention Clinic, RS Pelni Jakarta, Indonesia, involving 61 adult patients who underwent carotid DSA. CTI was measured bilaterally using digital imaging software and classified as <1.2 (non-tortuous) or ≥1.2 (tortuous). Clinical data, including age, sex, and hypertension status, were collected from medical records and analyzed using bivariate tests. Results: Older age (≥65 years), female sex, and hypertension were significantly associated with higher CTI values on both carotid sides. Tortuosity was more common among hypertensive patients and elderly females, indicating the influence of vascular remodeling and chronic hemodynamic stress. Conclusion: Carotid tortuosity increases with age, hypertension, and female sex. DSA-based CTI measurement provides a reliable and precise approach for evaluating vascular changes associated with cerebrovascular risk.
