COVID-19 and liver dysfunction: What nutritionists need to know.

The coronavirus disease 2019 (COVID-19) pandemic caused by severe acute respiratory syndrome coronavirus-2 has brought serious challenges for the medical field. Patients with COVID-19 usually have respiratory symptoms. However, liver dysfunction is not an uncommon presentation. Additionally, the degree of liver dysfunction is associated with the severity and prognosis of COVID-19. Prevention, diagnosis, and treatment of malnutrition should be routinely recommended in the management of patients with COVID-19, especially in those with liver dysfunction. Recently, a large number of studies have reported that nutrition therapy measures, including natural dietary supplements, vitamins, minerals and trace elements, and probiotics, might have potential hepatoprotective effects against COVID-19-related liver dysfunction via their antioxidant, antiviral, anti-inflammatory, and positive immunomodulatory effects. This review mainly focuses on the possible relationship between COVID-19 and liver dysfunction, nutritional and metabolic characteristics, nutritional status assessment, and nutrition therapy to provide a reference for the nutritionists while making evidence-based nutritional decisions during the COVID-19 pandemic.

Potential role of vitamin D in patients with diabetes, dyslipidaemia, and COVID-19.

Coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus-2 has become a worldwide public health crisis. Studies have demonstrated that diabetes and dyslipidaemia are common comorbidities and could be high-risk factors for severe COVID-19. Vitamin D, a group of fat-soluble compounds responsible for intestinal absorption of calcium, magnesium, and phosphate, has been widely used as a dietary supplement for the prevention and treatment of numerous diseases, including infectious and non-infectious diseases, due to its high cost-effectiveness; safety; tolerability; and anti-thrombotic, anti-inflammatory, antiviral, and immunomodulatory properties. In this letter to the editor, we mainly discuss the potential role of vitamin D in patients with diabetes, dyslipidaemia, and COVID-19.

Traditional Chinese medicine combined with conventional therapy for female kidney stone: A protocol for systematic review.

INTRODUCTION: Kidney stone is caused by abnormal accumulation of crystalline substances in the kidneys. Kidney stone is one of the urinary system diseases with a high incidence. In this study, we will use the research method of randomized controlled trials to explore the effects of Traditional Chinese medicine combined with western medicine on renal function and urine metabolism in women with kidney stones. We hope that the results of this study will provide more evidence-based medical evidence for TCM to treat kidney stones, and also provide patients with more treatment options. METHODS/DESIGN: This pragmatic randomized controlled trial will recruit 100 patients who are diagnosed with kidney stone. Simple randomization to conventional drug treatment with a 1:1 allocation ratio will be used. The participants will continue to receive ESWL treatment and TCM therapy. The selection of outcomes will be evaluated by the overall effectiveness of clinical efficacy. DISCUSSION: This trial may provide evidence regarding the clinical effectiveness, safety, and cost-effectiveness of Traditional Chinese medicine for patients with Female kidney stone.
