Mortality from Stroke in Young People in Brazzaville

Introduction: Cerebrovascular accidents (CVA) are an absolute neurovascular emergency and the main cause of mortality and acquired disability in adults. In the Congo, stroke is the leading cause of mortality and the leading cardiovascular emergency, with a hospital frequency of between 49.74% and 56.2%. The aim of the study was to identify the mortality factors associated with stroke in young people in Brazzaville. Patients and Methods: This is a longitudinal analytical study conducted from February to period from February to September 2019 in the neurology, general intensive care and medical emergency departments of the Brazzaville University Hospital (CHUB). All subjects aged 18 - 55 years of completed age, admitted for arterial stroke confirmed by brain imaging, were included. Study variables were: age, gender, socioeconomic level, laterality, time to admission and CT scan, vascular risk factors, history of cardiomyopathy, atrial fibrillation, TIA (transient ischemic attack) or stroke, NIHSS (National Institutes of Health Stroke Scale) score, Glasgow score, blood pressure, temperature, heart rate, occurrence or non-occurrence of complications, blood glucose, creatinine, lipid profile and blood count. Data were analyzed using SPSS 21 software. Descriptive analyses were performed using SPSS 21 software. Results: 103 patients were included in the study, of whom 45 (43.7%) had ischemic stroke and 58 (56.3%) with hemorrhagic stroke. Mortality was high at 29.1% in our study, and mainly concerned hemorrhagic strokes (73.7%). Two-week mortality in our study accounted for 63.33% of total lethality. After simple logistic regression, the factors associated with death within two weeks were age between 40 - 44 years (OR (odds ratio) = 2.95;p = 0.01), hemorrhagic stroke (OR = 1.41;p = 0.07), mass effect (OR = 3.26;p < 0.01), ventricular flooding (OR = 2.86;p < 0.001), Glasgow score (OR = 2.95 (0.92 - 9.43);p = 0.06), NIHSS score on admission > 15 (OR = 5.89 (2.90 - 11.95);p < 0.001) and bronchopulmonary infection (OR = 30, 95 (4.04 - 236.88), p < 0.001). From multivariate logistic regression, only NIHSS score on admission > 15 emerged as a predictor of death within two weeks (OR = 5.89 (2.90 - 11.95);p Conclusion: This study confirms the basic data of the African literature concerning stroke, as several factors were identified as independent factors associated with mortality.

Analysis of Regional Differences in Bone Mineral Density Acquisition Factors in Young Women

Purpose: Obtaining high peak bone mass (PBM) and maintaining bone mass is important for the prevention of osteoporosis. This study aimed to examine the regional differences in bone mineral density and factors associated with its acquisition from exercise. Design: The study population included 75 women of 18 - 22 years of age in East Japan and 104 women of 18 - 27 years of age in West Japan. The speed of sound (SOS) of the calcaneus was measured, and the young adult mean (%YAM) was calculated from the SOS. The subjects’ medical history, family history of osteoporosis, and exercise habits were examined using a self-administered questionnaire. Results: There were a significantly greater number of subjects with low %YAM in West Japan. The exercise history and exercise time were significantly higher in West Japan, and the exercise intensity score tended to be higher in East Japan during junior high and high school. A multiple regression analysis by region revealed that the following factors had a significant positive association with the SOS: exercise intensity at elementary school and outdoor sports at junior high school in East Japan;and exercise time at elementary school, muscle mass, and outdoor sports at junior high school in West Japan. On the other hand, exercise time in junior high school in West Japan showed a negative association with the SOS. Conclusions: Regional differences in bone mineral density existed, suggesting a trend toward lower bone mineral density in West Japan. Exercise history and time tended to be higher in West Japan, and exercise intensity scores tended to be higher in East Japan, suggesting that exercise intensity may be more important than exercise time for obtaining bone mineral density.

Provision of Fertility Preservation for Young Women with Early-Stage Breast Cancer

Breast cancer is the most common cancer in women worldwide, constituting 25% of all cancer diagnoses. Even though it is only affecting 4% - 6% of women under the age of 40, it remains the most common malignancy among younger patients. Advancement in the treatment and earlier detection gives excellent 5 years of survival. However, the standard treatment that comprises surgical-chemo radiation therapy or hormonal treatment often results in an increased incidence of treatment-induced infertility. Therefore, adding fertility preservation to primary cancer treatment may offer the best opportunity for future fertility. However, despite advancements in Assisted Reproductive Technology (ART), the uptake of fertility services in this group remains low. In this review, we highlighted the effect of all breast cancer treatments on women’s fertility, the effectiveness and safety of ART in breast cancer patients as well as the safety of pregnancy in breast cancer survivors. Our aim is to improve awareness of fertility preservation for breast cancer to ensure all women diagnosed with breast cancer have multidisciplinary approaches with early referral to fertility specialists to discuss regarding potential risks and benefits of fertility preservation to improve the uptake of fertility preservation among this group of patients.

Spontaneous Bilateral Pneumothorax in a Healthy Young Adult: A Comprehensive Case Report

Background: Spontaneous bilateral pneumothorax in healthy young adults is a rare and challenging condition that defies conventional diagnostic and etiological paradigms. This case report explores the presentation, diagnostic evaluation, management, and potential contributing factors in a 29-year-old male with no prior medical history who experienced bilateral spontaneous pneumothoraces. Aim: This case report aims to shed light on the complexities of managing spontaneous bilateral pneumothorax, particularly in the absence of common risk factors. It underscores the need for a thorough assessment and ongoing research to unravel the enigma surrounding this condition. Case Presentation: A healthy 29-year-old male presented with acute chest pain and shortness of breath, ultimately diagnosed with bilateral spontaneous pneumothoraces. Despite the absence of typical risk factors, advanced imaging techniques revealed valuable insights into the diagnosis and management of this unique presentation. Conclusion: Spontaneous bilateral pneumothorax in healthy individuals presents diagnostic challenges and raises questions about potential genetic predisposition, connective tissue disorders, and lifestyle-related triggers. While the acute phase was effectively managed, this case underscores the importance of interdisciplinary collaboration and ongoing research to comprehensively understand this condition.

“体教融合”视域下青少年运动员培养中家庭融合的困境及化解路径

党的十八大以来,随着“体教融合”等系列青少年体育纲领性政策的颁布及实施,家庭力量更深融入青少年运动员培养是一个必然趋势,而家庭协同参与所面临的诸多现实困境,成为制约“体教”深度融合的关键因素。采用文献资料法、逻辑分析法、问卷调查法,对“体教融合”发展中家庭融合所面临的困境及化解路径进行探究。认为家庭在青少年运动员培养中的角色定位是运动员生源基础的储备者、运动员全面发展的保障者、运动员发展资源的协同者、运动员竞技训练风险的应对者和运动员权益保障的监督者。家庭主动理念和主体认同的缺失、家庭自主能力的不足和家庭利益诉求的受阻是其融于青少年运动员培养体系所面临的主要困境。化解以上困境的关键路径是强化家庭融合角色、塑造传统家庭育人文化、创建家庭参与制度、建设家庭融合智慧平台、设立家庭组织机构,从而提高家庭融入青少年运动员培养的自主与协同治理能力。

Association of Vitamin D Deficiency with Diabetic Retinopathy in Young People with Type 1 Diabetes Mellitus

Background: Diabetic retinopathy is among the most common diabetic complications, and is one of the leading causes of blindness in the world. Recent studies have linked vitamin D to the pathogenesis of diabetes and there is growing evidence that vitamin D can interfere with the mechanisms involved in diabetes and its complications. Despite improvements in treatment, diabetic retinopathy remains a significant complication of type 1 diabetes mellitus. Identification of early treatable predictors of diabetic retinopathy such as vitamin D deficiency, may allow more aggressive management of those at high risk. Purpose: To assess the association of vitamin D deficiency with diabetic retinopathy in young people with type 1 diabetes mellitus. Design: Observational study with case control design. Method: 60 young people with type 1 diabetes aged between 11 to 24 years were included in this study. Among them, 30-young people have diabetic retinopathy and 30-young people do not have diabetic retinopathy. Purposive sampling technique was applied as per inclusion criteria. Statistical analysis of the results was done by using computer-based software, SPSS version 26. P value of less than 0.05 was considered as statistically significant. Results: Vitamin D deficiency was present in 83% of the young people with diabetic retinopathy and in 53% without diabetic retinopathy. The mean vitamin D level in young people with and without diabetic retinopathy was 17.38 ± 3.77 ng/ml and 20.15 ± 5.06 ng/ml respectively and the difference was statistically significant (p = 0.019). Vitamin D deficiency was increased with the severity of diabetic retinopathy. Univariate and multivariate logistic regression showed vitamin D deficiency was independently associated with diabetic retinopathy with a crude odds ratio of 5.69 with a p value of 0.008 and adjusted odds ratio of 16.08 with a p value of 0.002 respectively. Conclusion: Result of the study revealed that vitamin D deficiency was strongly associated with diabetic retinopathy in young people with type 1 diabetes mellitus.
