The Effect of Vitamin D Supplementation on Symptoms of Depression in Patients with Type 2 Diabetes Mellitus: A Systematic Review and Meta-Analysis of Randomized Controlled Trials.

BACKGROUND: The effect of vitamin D supplementation on depressive  symptoms in people with type 2 diabetes is still up for debate. The aim of this paper was to investigate the effect of vitamin D supplementation on symptoms of depression in type 2 diabetic patients. METHODS: The protocol for this review has been registered in PROSPERO:CRD42021231713. Searching for literature was conducted using Pubmed, EBSCOhost, and EMBASE. Randomised controlled trials (RCTs) regarding vitamin D supplementation in type 2 diabetic patients with depression were retrieved through a systematic search. The outcome measured was a change in depressive symptoms evaluated with any validated rating scale. Independent data extraction was conducted, and the study quality was assessed. A meta-analysis was carried out to calculate the improvement in depressive symptoms in the group receiving vitamin D and the control group. The available evidence in RCTs was analysed using the PRISMA approach, and clinical significance was determined using the GRADE system. Risk of bias was assessed using the Cochrane Risk of Bias Tool. RESULTS: Four RCTs were reviewed and three RCTs were meta-analysed. In two studies, vitamin D was statistically effective in improving depressive symptoms in type 2 diabetic patients. Three randomised controlled trials  were included in the meta-analysis with 161 subjects using depression score as an outcome assessment. Vitamin D is significantly more effective than placebo (95% CI: -0.70 to - 0.08, p = 0.01). CONCLUSION: Vitamin D supplementation is effective in improving depressive symptoms in type 2 diabetic patients. Future research with different geographical areas and larger samples should be done to further assess the benefits.

Relationship Between Quality of Life of People with Dementia and Their Caregivers in Indonesia.

BACKGROUND: Caregivers, as one of the most important roles in caring for a person with dementia, have a challenging task. Therefore, maintaining the quality of life (QoL) of caregivers is an integral part of dementia care. OBJECTIVE: To explore the relationship between the QoL of people with dementia and their caregivers in Indonesia. METHODS: This is a cross-sectional study using binary correlations to analyze the relationship between people with dementia and caregivers' QoL. Conducted in Cipto Mangunkusumo Hospital in Jakarta, the subjects were 42 people diagnosed with dementia according to the PPDGJ-III (adapted from the ICD 10) and 42 primary caregivers with at least 6 hours duration of caregiving per day. The QoL of people with dementia was measured by EuroQol-5D and VAS EQ-5D, while severity of dementia was measured by MMSE. Caregivers underwent an interview using WHO Quality of Life Instrument (WHOQOL-BREF) and NPI. RESULTS: Most caregivers were women, aged 40-70 years old. The study found caregivers' QoL environmental domain strongly correlated with people with dementia's QoL (r = 0.839). Severity of dementia had a strong correlation with caregivers' QoL physical domain (r = 0.946). Age, duration of caregiving per day, period of care provided by caregivers, and caregiver's distress had a strong correlation with caregiver QoL for specific domains. CONCLUSION: There was a strong correlation between people with dementia's QoL and caregiver QoL, so in managing dementia, clinicians should consider caregivers' wellbeing as an essential part significantly affecting the quality of elderly care improvement.
