Clinical characteristics, HPV involvement, and demographic risk factors in women with cervical intraepithelial neoplasia complicated by vaginal intraepithelial neoplasia.

PURPOSE: This study aimed to explore the clinical characteristics and risk factors associated with cervical intraepithelial neoplasia (CIN) when coexisting with vaginal intraepithelial neoplasia (VAIN). METHODS: We analyzed the clinical data of 212 patients diagnosed with CIN, including 50 patients with concurrent VAIN. The groups were compared to identify distinct clinical features and independent risk factors for the co-occurrence of CIN and VAIN, using logistic regression analysis. RESULTS: Patients with both CIN and VAIN had a median age of 57, significantly older than the 41-year median age of patients with CIN only (P < 0.05). A higher prevalence of HPV infection (98.0%) was observed in the CIN and VAIN group, with a notable rate of multiple HPV infections (67.3%) compared to the CIN-only group (P < 0.05). Educational levels were significantly lower in the combined CIN and VAIN group (P < 0.05). HPV16, 33, and 52 were identified as significant types for single and multiple infections. Multivariate analysis confirmed age as an independent risk factor for CIN with VAIN (P < 0.05). VAIN3 patients were more likely to exhibit HSIL and ASC-H, whereas VAIN1 cases tended to correspond with ASCUS and LSIL diagnoses. CONCLUSION: The co-occurrence of CIN and VAIN is significantly influenced by patient age and educational level. The findings advocate for more diligent vaginal examination during colposcopy in older patients, particularly those with multiple HPV infections and cytological abnormalities, to enhance the early detection of vaginal lesions and prevent missed diagnoses and treatments. Additionally, the high prevalence of HPV infection, especially with certain types, underscores the importance of HPV monitoring in this patient population.

Genetic Polymorphism of E2F1 Influences Susceptibility to Ovarian Cancer in a Chinese Population.

Purpose: The present study is aimed at exploring whether rs3213172, rs3213173, and rs3213176 polymorphisms of the E2F1 gene confer risk for ovarian cancer. Methods: A total of 80 patients with ovarian cancer were selected from the first affiliated hospital of Soochow University in Jiangsu Province from January 2016 to June 2021, including 48 cases that were premenopausal and 32 cases that were menopausal. 130 healthy women who participated in normal physical examinations during the same period were selected as the control group. The rs3213172, rs3213173, and rs3213176 polymorphisms of the E2F1 gene were detected by the fluorescent probe method. Results: For rs3213173 and rs3213176 loci, there were no statistical significances in genotype distribution frequency between the ovarian cancer group and the control group (P > 0.05). For rs3213172 loci, a significant difference was observed in CT genotype between the ovarian cancer group and the control group (P=0.024). Conclusion: E2F1 gene rs3213173 and rs3213176 polymorphisms confer no risk to ovarian cancer risk. The CT genotype of E2F1 gene rs3213172 polymorphism is associated with an increased risk of ovarian cancer, and E2F1 gene rs3213172 polymorphism may be a novel marker for the risk prediction of ovarian cancer.

A New Method for Postural Misalignment of a 6-Year-Old Girl With Cerebral Palsy: A Case Report.

OBJECTIVE: To demonstrate the effects of a newly designed postural alignment relearning system on postural control dysfunction in a typical patient with cerebral palsy (CP). DESIGN: Evaluation before and after 8 weeks of Constraint Standing Training 3-dimensional postural alignment relearning system. SETTING: Department of Rehabilitation Medicine. PARTICIPANT: A 6-year-old girl with CP and postural misalignment on Gross Motor Function Classification System level I. INTERVENTIONS: Constraint Standing Training for 8 weeks to correct postural misalignment. MAIN OUTCOME MEASURES: Parameters of lateral plain radiographs in static standing, posturography measurements in standing and walking, motor ability (Gross Motor Function Measure-88 [GMFM-88] scores, manual muscle testing [MMT] scores, muscle architecture), and gait kinematic parameters (40 3-dimensional parameters of arms, trunk, waist, and lower limbs). RESULTS: Knee hyperextension angle in static standing; peaks of knee flexion angle (KFA) when walking, hip flexion angle and ankle flexion angle in dynamic standing; and the KFA at initial contact in gait cycle all decreased significantly (P<.01). Scores of GMFM-88 sections D and E and MMT of 5 core stability muscles improved (P<.01). The velocities and range of motion of the arms, the 3-dimensinoal range of motion of the trunk and waist, and most of the parameters of the lower limbs showed statistically significant change (P<.01). Bilateral muscle thickness did not change significantly after the treatment (P=.738 left, P=.978 right), but the gluteus maximus morphology was changed: the muscle fibers became rounder, the interfiber space decreased, and the border lines of the muscle fibers got clearer. CONCLUSIONS: Postural alignment, motor ability, and gait may be homologous external manifestations of more fundamental core abilities, referring to correct standing posture cognition, muscle activation, and postural unconsciousness. Constraint Standing Training 3-dimensional postural alignment relearning system aimed to improve the static and dynamic standing control ability, may fix postural misalignment and improve motor ability and flexed-knee gait. Future work should use Constraint Standing Training with patients with different kinds of misalignment, choose sensitive indicators, observe the duration of each step, and reveal the mechanism causes postural misalignment.

Impact of Hajj on Global Health Security.

With the human society transfers from scattered pieces to a society as a whole and the advent of the aviation era, the occurrence of infectious diseases and their diffusion have led to international health security issues. As the world's largest and irrevocable annual transnational religious movement, the Hajj and its connection with health security concerns have caught attention since the ancient times, because a huge population from all over the world gathers in the holy city of Mecca, which has tropical arid climate. Currently, the international community and international organizations are implementing multilevel governance with respect to the health security issues of the Hajj. Relevant agencies include the World Health Organization and its regional branches, International Red Cross and Red Crescent Movement (ICRC), the Ministry of Hajj as well as the Ministry of Health of Saudi Arabia, and the public health sectors/agencies in various countries that are involved with Hajj activities. The international community has successfully held the Hajj events, even when facing the challenges brought by some viral respiratory diseases such as SARS and MERS. The Hajj has become a rare opportunity for all stakeholders to improve their capabilities in international health security governance.

Proteomic characteristics of circulating microparticles in patients with newly-diagnosed type 2 diabetes.

OBJECTIVE: This study aimed to evaluate the proteomic characteristics of plasma microparticles (MPs) from patients with newly diagnosed type 2 diabetes (T2DM). METHODS: The subjects comprised eight male T2DM patients recruited between December 2013 and March 2014, as well as eight age and sex-matched healthy controls enrolled during the same period. Plasma microparticles (MPs) were extracted from the blood of each subject, and subjected to proteomics analysis using label-free methods. Bioinformatic analyses were performed using specialized software. RESULTS: 3,148 unique peptides and 496 proteins were identified, among these, 46 proteins were differentially expressed between the two groups. Among these 46 candidates, 20 proteins had higher expression in T2DM group compared with the control group, whereas 3 proteins displayed lower expression. There were 17 proteins only detected in T2DM group, and 6 proteins only detected in the control group. Gene ontology (GO) analysis revealed significant differences between the two groups in some functional nodes, including neutrophil accumulation, chemokine production, platelet activation, and blood coagulation. Pathway analysis showed that proteins involved in platelet activation, cell adhesion, focal adhesion, and extracellular matrix-receptor interaction were differentially expressed between the 2 groups. Network analysis indicated that ubiquitin was the protein with the highest degree of connectivity. CONCLUSIONS: Blood MPs from T2DM patients are enriched in proteins involved in platelet activation, cell adhesion, and inflammation. Therefore, MPs in T2DM patients might be associated with hypercoagulable state in diabetic patients and the development of diabetic complications.
