Forty percent of the world's population is at risk of Plasmodium vivax infection. Relapse is a feature of malaria caused by P. vivax and P. ovale due to the presence of the parasite's hypnozoite stage that allows it to stay dormant in the human liver. The associated morbidity and economic burden is high, as P. vivax causes severe anemia, miscarriage among pregnant women, malnutrition, and developmental delay in young children due to its chronic relapsing nature. Till recently, for more than 60 years the only licensed antimalarial with proven hypnozoitocidal activity was primaquine. The World Health Organization recommends a regimen of 3-day chloroquine plus 14 days of primaquine for radical cure. Poor adherence to the primaquine course limits its public health benefit on a large scale. Tafenoquine is an 8-aminoquinoline with slower elimination rate, hence a single dose of it is sufficient for hypnozoitocidal activity. Additionally, the schizontocidal activity of tafenoquine makes it a superior drug to the currently available antimalarials, which are mostly single stage specific. Recently, tafenoquine was approved in the USA and Australia for the radical cure of P. vivax malaria in patients aged ≥16 years who are receiving appropriate antimalarial therapy for acute P. vivax malaria, and for the prophylaxis of malaria in patients aged ≥18 years. We have reviewed the available literature of tafenoquine here, and this article explores the possibility of tafenoquine as a key tool for control and elimination of malaria.

The entirety of food and drink that an individual continually expends is called a diet. Proper nutrition – a sufficient, all-around offset diet with regular physical activity, frames the establishment for good health. The majority of the currently prevalent dietary recommendations are based on the health benefits of different individual food products. With the rising concern regarding climate change and evidence highlighting the influence of our nutritional practices on the environment, the time has come to redefine the dietary guidelines and recommendations considering the environmental impact of diet along with the health benefits. Studies have been reliably consistent with demonstrating that an equicaloric diet rich in plant-based products and lower in animal products is beneficial to health and put a lesser burden on the earth. There are five Sustainable Developmental Goals that can be linked with our dietary practices (no poverty, no hunger, good health and well-being, responsible consumption and production, and climate change). A plant-based diet is a suitable solution to the current crisis of noncommunicable diseases and climate change. Moving on to such a dietary practice would require immense changes in the currently prevalent food system with an emphasis on better production and waste management strategies along with improvement in food delivery and consumption practices worldwide. This article brings insight regarding the benefits of a plant-based diet and the need to address the ecological impact of animal-based foods.

Anabolic androgenic steroids (AAS) include endogenously produced androgens like testosterone and their synthetic derivatives. Their influence on multiple metabolic pathways across organ systems results in an extensive side effect profile. From creating an atherogenic and prothrombotic milieu to direct myocardial injury, the effects of AAS on the heart may culminate with patients requiring thorough cardiac evaluation and multi-disciplinary medical management related to cardiomyopathy and heart failure (HF). Supraphysiological doses of AAS have been shown to induce cardiomyopathy via biventricular dysfunction. Advancement in imaging including cardiac magnetic resonance imaging (MRI) and additional diagnostic testing have facilitated the identification of AAS-induced left ventricular dysfunction, but data regarding the impact on right ventricular function remains limited. Emerging studies showed conflicting data regarding the reversibility of AAS-induced cardiomyopathy. There is an unmet need for a systematic long-term outcomes study to empirically evaluate the clinical course of cardiomyopathy and to assess potential targeted therapy as appropriate. In this review, we provide an overview of the epidemiology, pathophysiology and management considerations related to AAS and cardiomyopathy.

Objective This study was aimed to compare the closure of skull base defect in endoscopic endonasal transsphenoid surgery of pituitary tumors, using bipedicled nasal septal flap versus fascial closure. The study hypothesis being that bipedicled nasal septal flap is better, compared with fascial closure of skull base defect post–endoscopic endonasal transsphenoid surgery of pituitary tumors. Methods All the eligible patients were randomly divided into two groups and then randomly allocated to the surgeons. In one group, fat and fascia lata was used for closure of the skull base defect and nasal septal flap was not harvested whereas in the other, nasal septal flap was used for closure. Result There was a statistically significant difference in postoperative cerebrospinal fluid leak between the two groups. Patients who had undergone flap repair had lower incidence of postoperative cerebrospinal fluid (CSF) leak. Duration of postoperative hospital stay was also less among the group who underwent flap repair (statistically significant). Conclusion Bipedicled nasal septal flap serves an excellent cover for the skull base defect following endoscopic endonasal transsphenoidal pituitary surgery. It can prevent postoperative CSF leak even in cases where tissue glue is not used.

Medical education is witnessing changes across the globe to produce more competent and responsive medical graduates to meet patients' growing needs. Medical educators are aspiring for more objective and relevant assessment methods for the evaluation of medical graduates. Objective structured clinical examination (OSCE) introduced in the year 1975 for clinical evaluation has gone through many changes over the past 45 years and matured over time. The article describes the challenges of OSCE as a tool in medical assessment from students' and organizers' perspectives. We have also suggested a feasible solution to address the challenges while conducting OSCE to assess medical students.
