The aim of this review article is find the status of artemisinin resistance and efficacy of different modalities of the current artemisinin-based combination therapies (ACTs).

Study design:
This review article included 82 studies for qualitative and quantitative analysis.

Objectives:
Do dietary intakes or circulating concentration of major dietary antioxidants, like vitamin C, E and beta-carotene reduce risk of total cardiovascular mortality?

Results and conclusions:

Objectives:
Does a dietary low-ratio n-6/n-3 PUFA supplementation improve risk factors (such as fasting blood glucose, HbA1c) of diabetes?

Study design:
This review article included 11 RCTs.

No significant publication bias was observed for all blood glucose and other related indicators as suggested by Begg's test and Egger's test.

Results and conclusions:
The investigators found no significant effect of dietary low-ratio n-6/n-3 PUFA supplementation on:

Objectives:

Hence, vitamin D administration might be an appropriate approach to decrease the complications of chronic kidney disease. Therefore, this review article has been conducted.

Have vitamin D supplements beneficial effects on people with chronic kidney disease?

Objectives:

Study design:
This review article included 6 cohort studies and 4 RCTs.
6 cohort studies included 225,062 participants (134,365 women and 90,697 men) aged 50 years or older. The participants’ follow-up time ranged from 2.8 years to 20 years.

Objectives:
Previous studies reported that magnesium deficiency was associated with vascular calcifications, atherosclerosis and cardiovascular disease, which might play an independent pathogenic role in chronic kidney disease (CKD) and end-stage renal disease (ESRD) patients. However, the results of these studies were somewhat underpowered and inconclusive. Therefore, this review article has been conducted.

Objectives:
Malaria transmission through blood transfusion is an accidental but preventable cause of malaria infection and is increasingly becoming a matter of concern for blood transfusion services. Therefore, this review article (meta-analysis) has been conducted.

Objectives:
The prevalence of overweight/obesity in adults is raised to 39%, which is nearly tripled more than 1975. The alteration of the gut microbiome has been widely accepted as one of the main causal factors. Therefore, this review article has been conducted.

Objectives:
HIV-infected children are at a higher risk of invasive pneumococcal disease (IPD) and its mortality, even in the era of antiretroviral therapy. Thus, an effective vaccination strategy would be beneficial. Therefore, this review article (meta-analysis) has been conducted.
