Objectives:
Type 2 diabetes mellitus is a chronic disease that occurs among the general population. The insulin-lowering and homeostasis model assessment of insulin resistance-improving effects of inulin are unconfirmed. Therefore, this review article has been conducted.

Objectives:
The coronavirus disease 2019 (COVID-19) pandemic has caused a significant impact on all aspects of life. One of the comorbidities associated with severe outcome and mortality of COVID-19 is diabetes. Metformin is one of the drugs which is most commonly used for the treatment of diabetes patients. Therefore, this review article has been conducted.

Objectives:
Severe Acute Respiratory Syndrome coronavirus-2 (SARS-CoV) has been recently characterized and soon spread around the world generating a pandemic. It has been suggested that men are more severely affected by the viral disease (COVID-19) than women. Therefore, this review article has been conducted.

Objectives:
What is the rate of transmission of COVID-19 within households?

Study design:
This review article included 10 retrospective cohort studies, 1 prospective study and 13 case ascertainment studies. Most studies (19/24) were conducted in China, with 2 in South Korea, 2 in the USA and 1 in Germany.
All the studies were conducted between Jan 1 and March 31, 2020.

Results and conclusions:   

Objectives:
Does chloroquine or hydroxychloroquine with or without azithromycin decreased the mortality of COVID-19 compared to standard of care?

Study design:

Objectives:
Isoflavones have a structure similar to 17β-estradiol, so they may be useful to postmenopausal women in preventing bone loss related to estrogen deficiency. Therefore, this review article has been conducted.

Objectives:
Since the World Health Organization recommended single low-dose (0.25mg/kg) primaquine (PQ) in combination with artemisinin-based combination therapies (ACTs) in areas of low transmission or artemisinin-resistant P. falciparum, several single-site studies have been conducted to assess its efficacy. Therefore, this review article has been conducted.

Objectives:
Steroids may play a critical role in the current pandemic of coronavirus disease (COVID-19), given the dearth of specific therapeutic options. Therefore, this review article has been conducted.

Objectives:
Coronavirus is challenging the global health care system from time to time. The pregnant state, with alterations in hormone levels and decreased lung volumes due to a gravid uterus and slightly immunocompromised state may predispose patients to a more rapidly deteriorating clinical course and can get a greater risk of harm for both the mother and fetus. Therefore, this review article has been conducted.

Objectives:
Hypertension is regarded as a major and independent risk factor of cardiovascular diseases and numerous studies observed an inverse correlation between vitamin C intake and blood pressure. Therefore, this review article has been conducted.
