In December 2019, an outbreak of pneumonia caused by a novel coronavirus occurred in Wuhan, the capital of Central China's Hubei Province and has been declared a public health emergency of international concern by the World Health Organization since January 2020. ⋯ Despite intensive research, the exact origin of the virus and pathophysiology of coronavirus disease is not yet completely known, and clinically approved vaccines and drugs that target severe acute respiratory syndrome coronavirus 2 are lacking.

The novel severe acute respiratory syndrome coronavirus 2 is the cause of Coronavirus Disease 2019, a new illness with no effective treatment or vaccine that has reached pandemic proportions. In this document, we analyze how health authorities and agencies around the world position themselves regarding the off-label use of repurposed drugs or new investigational drugs to treat Coronavirus Disease 2019. We review the most promising candidate medicines, including available evidence, clinical recommendations and current options for access. Our concluding remarks stress the importance of administering off-label and investigational drugs in the setting of clinical trials, or at least in standardized scenarios, to generate as much scientific knowledge as achievable while engaging in the best efforts to treat patients and save lives.

Recently, vitamin D has gained importance as a diabetes risk modifier. Our aim was to assess the association between serum vitamin D levels and the prevalence of diabetic retinopathy in patients with type 1 diabetes. ⋯ Lower levels of vitamin D were associated with an increased prevalence of diabetic retinopathy in patients with type 1 diabetes, after adjusting for possible confounders. Future controlled studies may elucidate the molecular routes for this association as well as the role of supplementation in the prevention of diabetes microvascular complications.

As populations live longer, they also aim to live better. A crucial step for this is to improve the understanding about older adults' physical and psychological health. Therefore, the aim of the present study was to characterise the Portuguese population over-65 regarding nutritional status, cognitive function, functional status, symptoms of depression, and loneliness, by sex and age groups. ⋯ This study contributed to a national characterisation of the health of older adults, that may inform policies and interventions targeted at the needs of the Portuguese aging population.

Graves disease is characterized by the existence of autoantibodies directed to the thyrotropin receptor, which can have a stimulatory/inhibitory action, in women with the condition, their fetus or neonate. Our aim was to review the case series of these neonates in order to establish neonatal thyroid function predictors. ⋯ High levels of free thyroid hormones during the second trimester of pregnancy and antibodies directed to the thyrotropin receptor value in cord blood are predictors of dysthyroidism in neonates born from women with Grave's disease.
