Medical data management presents significant challenges in terms of security, privacy, and efficiency. Blockchain technology has emerged as a promising solution to address these concerns in recent years. This comprehensive review explores the role of blockchain technology in secure and efficient medical data management. By providing a decentralized and immutable ledger, blockchain ensures data integrity, enhances privacy, and facilitates auditable access to medical information. The paper examines various applications of blockchain in medical data management, including electronic health records (EHRs), medical imaging, clinical trials, telemedicine, and drug supply chain management. It highlights the benefits and challenges of implementing blockchain in healthcare settings, discussing interoperability, consent management, scalability, and regulatory considerations. The review encompasses relevant research studies, industry initiatives, and real-world use cases to provide a comprehensive overview of the current state of blockchain technology in medical data management. The paper concludes with a discussion of future directions and potential areas for further research, emphasizing the transformative potential of blockchain in revolutionizing the way of medical data storage, sharing, and utilization.

Hyponatremia and hyperglycemia are common metabolic disorders which could worsen the outcome after a cerebrovascular accident (stroke). This study aimed to evaluate the impact of hyponatremia and hyperglycemia on stroke and its clinical outcome, including morbidity and mortality. This prospective cohort study included 50 stroke patients admitted in tertiary care hospitals. Stroke severity, Glasgow coma scale (GCS), conscious level, gag reflex, clinical presentations, and outcomes were recorded. Following a stroke, patients were monitored for a period of six months, during which the patient's death was recorded on the event form. Linear logistic regression model was used to determine the stroke mortality. Hyponatremia and hyperglycaemia were associated with higher odds ratio of deaths, poor functional recovery, severe disability, low mean GCS score as compared to normonatremic and normoglycemic patients (odds ratio [OR] = 4.7; 95% CI= 0.929-43.782) and hyperglycaemia (OR= 2.74; 95% CI=0.577-13.03). Stroke patients admitted with hyperglycemia or hyponatremia were associated with greater morbidity and mortality and poor functional recovery.

COVID-19 pandemic has brought a paradigm shift in education with a trend of online learning and even schooling. During complete lockdown period schools were shifted to smartphones and computers. This study aimed to explore the pattern of smartphone use before and after the COVID-19 pandemic and the health issues of school-going children in post-COVID-19 period. There was a significant rise in the timings of mobile phone use from 2 hours to 7 hours per day. A total of 90% of student’s mothers reported behavioral change where lack of socializing was the most commonly reported change. Irritation of eyes and dryness were the most commonly reported ocular disorders.  The rise of mobile phones has brought several behavioral and ocular disorders due to long hours of use. There is a need to confirm health-related issues of smartphone use in large prospective studies and develop preventive strategies.
