Background And Aim: Increasing stroke burden in developing countries necessitates measures to strengthen health systems. We aimed to evaluate whether a Community Health Worker (CHW) based educational intervention will improve risk factor control among stroke survivors and enhance behavior change communication.
Method: An open-label, cluster-randomized trial was conducted in rural area of Thiruvananthapuram district, Kerala from December 2017 to December 2018. A CHW-based educational intervention in addition to standard of care was provided in intervention arm and compared to standard clinical care in the control arm with follow-up at three and six months. The primary outcome measures were risk factor control and quality of behavior change communication provided by CHWs.
Results: Of the 234 Stroke/TIA survivors enrolled, the mean age (SD) was 59.43 (11.07) years. At 6-month follow up, all patients with smokeless tobacco consumption had quit in the intervention arm (5 at baseline and 0 at six months) and no relapse in smoking was found (as compared to control arm wherein 9 at baseline and one at 6 months). The control of hypertension and diabetes was not significant at 3 months and 6 months in both intervention and control groups. Home visits as well as health education on risk factors by CHWs in the intervention arm were significantly higher.
Conclusion: Community health worker-based intervention is feasible in resource constrained settings for secondary stroke prevention. Training of CHW on risk factor control and lifestyle modifications for stroke survivors enhances quality of health education provided by health services.

Background: Near-infrared spectroscopy (NIRS) enables a non-invasive measurement of tissue oxygen saturation (StO) in regions illuminated by near-infrared lights. Vascular occlusion test (VOT) serves as a model to artificially induce forearm ischemia-reperfusion. The combination of StO monitoring and VOT allows for dynamic evaluation of the balance between oxygen delivery and consumption in tissue, as well as the functional reserve of microcirculation.

Background: The Compress is designed to achieve bone formation and stability by applying pressure at the bone-implant interface, minimizing the likelihood of aseptic loosening, which is a complication of stem implants. Herein, we report two cases of implant failure using the Compress.
Case Presentation: Case 1 describes a 36 year-old Japanese man who underwent extraarticular tumor resection, Compress arthroplasty, and reconstruction with a gastrocnemius flap after preoperative chemotherapy for a secondary malignant giant cell tumor in the right distal femur.

Background: Adequate knowledge and awareness regarding diseases are essential for appropriate, high-quality healthcare. Female Genital Schistosomiasis (FGS) is a non-sexually transmitted gynaecological disease that is caused by the presence of Schistosoma haematobium eggs in the female genital tract and the resulting immune response that causes tissue damage. It is estimated to affect 56 million women, mostly in sub-Saharan Africa (SSA), where healthcare workers (HCWs) have limited awareness and knowledge of FGS.

Background: Despite advancements in Human Immunodeficiency Virus (HIV) treatment and care, undernutrition remains a significant concern, accelerating disease progression and risk of Acquired Immune Deficiency Syndrome (AIDS)-related deaths. The nutritional status of second-line antiretroviral treatment (SLART) users in Ethiopia has not been thoroughly investigated. So, this study aimed to assess the nutritional status of HIV/AIDS patients who were on SLART and its associated factors in Northern Ethiopia.
