The current pandemic of coronavirus disease 2019 caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has presented unprecedented challenges to the healthcare systems in almost every country around the world. Currently, there are no proven effective vaccines or therapeutic agents against the virus. Current clinical management includes infection prevention and control measures and supportive care including supplemental oxygen and mechanical ventilatory support. Evolving research and clinical data regarding the virologic SARS-CoV-2 suggest a potential list of repurposed drugs with appropriate pharmacological effects and therapeutic efficacies in treating COVID-19 patients. In this review, we will update and summarize the most common and plausible drugs for the treatment of COVID-19 patients. These drugs and therapeutic agents include antiviral agents (remdesivir, hydroxychloroquine, chloroquine, lopinavir, umifenovir, favipiravir, and oseltamivir), and supporting agents (Ascorbic acid, Azithromycin, Corticosteroids, Nitric oxide, IL-6 antagonists), among others. We hope that this review will provide useful and most updated therapeutic drugs to prevent, control, and treat COVID-19 patients until the approval of vaccines and specific drugs targeting SARS-CoV-2.
Summary. The effects of 6 weeks of thrice weekly training on glycaemic control were assessed in 20 sedentary Type 2 (noninsulin-dependent) diabetic patients and 11 control subjects matched for previous physical activity. Maximal oxygen uptake was lower in the diabetic patients than in control subjects before training (26.2 + 1.1 versus 32.6___ 1.7 ml. kg -1. min -1 ; p < 0.001). Glycosylated haemoglobin levels decreased in the diabetic patients during the training programme (12.2 + 0.5 to 10.7 + 0.4%; p < 0.02). Oral and intravenous glucose tolerance determined 72 h after the last exercise period showed only minimal improvement. Plasma glucose levels were, however, significantly lower at 12 h than 72 h after exercise in eight subjects tested at both time points. These data suggest that an exercise programme can produce a significant decrease in glycosylated haemoglobin levels in Type 2 diabetic males probably due, in great measure, to the cumulative effect of transient improvements in glucose tolerance which follow each individual period of exercise.
Posterior pilon fractures are injuries of the posterior tibial plafond that likely occur through a combined rotational and axial load mechanism and are often difficult to treat with standard surgical approaches to the ankle. We describe an alternative surgical approach to this injury using posteromedial, posterolateral, or combined approaches and present a series of patients with either radiographic or functional outcomes at a minimum of 1-year follow up that were treated by this method.
Experimental evidence suggests a central-nervous-system origin of Cushing's disease and a role for serotonin in the regulation of ACTH release. The efficacy of cyproheptadine therapy, therefore, was studied in three patients with such disease. Administration of 24 mg daily over a period of three to six months was associated with prompt and sustained clinical and laboratory remission. Lessening of the physical manifestations of hypercorticism occurred, together with marked improvement in muscular weakness. Urinary corticosteroid excretion and cortisol secretory rate returned to normal. The urinary corticosteroid response to dexamethasone (2 mg per day) became normal; a paradoxical increase followed 8 mg per day. Abnormal circadian periodicity of plasma cortisol concentrations persisted. Return of normal amounts of Stage III to IV sleep occurred in the one patient so studied, who previously had markedly decreased periods of these stages. Discontinuance of therapy in one patient was associated with return of laboratory evidence of hypercorticism.
Exercise is frequently recommended in the treatment of diabetes mellitus. Nevertheless, its use has been limited in clinical practice, and concerns about safety and efficacy persist. We have reviewed a 10-yr experience with 255 patients enrolled in a comprehensive diabetes program that emphasized physical training. A low maximal oxygen uptake (VO2max) was found in patients with non-insulin-dependent diabetes mellitus compared with sedentary control subjects. This was not accounted for by autonomic neuropathy and is unlikely to be due to subtle differences in life-style. Exercise-related proteinuria was common and occurred in 29% of patients and was associated with higher blood pressure levels at rest and during exercise, impaired VO2max, and decreased R-R interval variation. Regular exercise was associated with a modest decrease in resting and exercise blood pressure. Glycosylated hemoglobin levels and plasma triglycerides improved only in patients with non-insulin-dependent diabetes mellitus. Insulin requirements were significantly reduced in patients with insulin-dependent diabetes mellitus. Compliance for up to 3 mo in the program was acceptable but longer-term compliance was poor. Serious complications during the program were rare. Our experience suggests a program of regular aerobic training can be safely and effectively used in an outpatient population with diabetes mellitus for up to 3 mo.
