The severe acute respiratory syndrome (SARS) coronavirus-2 is a novel coronavirus belonging to the family Coronaviridae and is now known to be responsible for the outbreak of a series of recent acute atypical respiratory infections originating in Wuhan, China. The disease caused by this virus, termed coronavirus disease 19 or simply COVID-19, has rapidly spread throughout the world at an alarming pace and has been declared a pandemic by the WHO on March 11, 2020. In this review, an update on the pathophysiology, clinical presentation and the most recent management strategies for COVID-19 has been described. ⋯ COVID-19 has now spread globally with increasing morbidity and mortality among all populations. In the absence of a proper and effective antibody test, the diagnosis is presently based on a reverse-transcription PCR of nasopharyngeal and oropharyngeal swab samples. The clinical spectrum of the disease presents in the form of a mild, moderate or severe illness. Most patients are either asymptomatic carriers who despite being without symptoms have the potential to be infectious to others coming in close contact, or have a mild influenza-like illness which cannot be differentiated from a simple upper respiratory tract infection. Moderate and severe cases require hospitalisation as well as intensive therapy which includes non-invasive as well as invasive ventilation, along with antipyretics, antivirals, antibiotics and steroids. Complicated cases may require treatment by immunomodulatory drugs and plasma exchange therapy. The search for an effective vaccine for COVID-19 is presently in full swing, with pharmaceutical corporations having started human trials in many countries.

Medical migration has become a global phenomenon, partly led by easier air travel, economic factors and the expansion of medical technology. New Zealand has gradually evolved from being 'bicultural' to a multicultural, multitextured society. The movement of the Indian people, particularly Indian physicians, will be the focus of this paper. ⋯ India is widely recognised as the largest 'donor country' for doctors, many of whom go on to establish themselves as leaders and prominent figures in their field. This migration involves three parties: India as a donor country, New Zealand as a recipient country and IMGs as the drivers of this process. Factors behind this growing phenomenon are examined and recommendations are made so that all three parties can benefit from it.

Given the fat redistribution in later stages of life, how the associations between abdominal obesity and the risk of morbidity and mortality have changed with age have not been elucidated, especially for waist to height ratio (WHtR). ⋯ WHtR and WC appeared to be the better indicators for cardiometabolic health than BMI. However, BMI had a stronger and inverse association with a greater risk of all-cause mortality among older females.

Facilitating radiological imaging for patients is an essential task for foundation year (FY) doctors. Achieving competence in this task can significantly enhance patient management. We evaluated the confidence and skills of FY doctors in facilitating radiological imaging before and after introduction of formal training. ⋯ There was a demonstrable benefit with focused training in improving these skills. This could potentially provide significant benefits in patient care and management. Interspecialty communication should be introduced into undergraduate and postgraduate educational curriculum.
