Severe Vitamin D Deficiency-A Possible Cause of Resistance to Treatment in Psychiatric Pathology.

In the last few years, vitamin D functions have been studied progressively, and along with their main role in regulating calcium homeostasis, the potential function in the nervous system and the link between different psychiatric disorders and vitamin D deficiency have been revealed. The discovery of vitamin D receptors in multiple brain structures, like the hippocampus, led to the hypothesis that vitamin D deficiency could be responsible for treatment resistance in psychiatric diseases. The aim of this study was to analyze the current knowledge in the literature regarding vitamin D deficiency among individuals afflicted with psychiatric disorders and assess the potential therapeutic benefits of vitamin D supplementation. A systematic search was conducted on the PubMed database for articles published in the last five years (2016-2022) in English, focusing on human subjects. Results show that vitamin D deficiency has implications for numerous psychiatric disorders, affecting mood and behavior through its influence on neurotransmitter release, neurotrophic factors, and neuroprotection. It also plays a role in modulating inflammation, which is often elevated in psychiatric disorders. In conclusion, vitamin D deficiency is prevalent and has far-reaching implications for mental health. This review underscores the importance of exploring the therapeutic potential of vitamin D supplementation in individuals with psychiatric disorders and highlights the need for further research in this complex field.

Quality of Life Predictors in a Group of Informal Caregivers during the COVID-19 Pandemic.

Background and Objectives: The informal caregiver's contribution to the wellbeing of dementia patients is critical since these individuals become dependent on others for all daily activities. Our goal was to investigate the dynamics of anxiety, depression, burnout, sleep, and their influence on quality of life over a 6-month period in the context of pandemic distress in a sample of informal caregivers of Alzheimer's patients. Materials and Methods: For this prospective, longitudinal study, we conducted a 6-month telephonic survey between 2021 and 2022, administering a series of questionnaires at three timepoints (baseline, 3 months and 6 months) to a group of informal caregivers of patients suffering from dementia due to Alzheimer's disease. Results: A total of 110 caregivers were included at baseline, out of which 96 continued to the second stage and 78 followed through to the last stage. The majority of the participants were female (most likely the patients' daughters), around 55 years old, living in urban areas, married, with children, having a high school degree or a higher education degree, and working in jobs that required physical presence; in the best-case scenario, they were sharing their responsibilities with another two-three caregivers. More than half of the 110 participants (50.9%) reported mild to moderate anxiety at baseline, and 27.3% reported significant anxiety, with no changes between the three timepoints, F(2, 154) = 0.551, p = 0.57; 25% reported moderate-severe depression at the start, with no changes between the three timepoints, F(2, 154) = 2.738, p = 0.068; and many reported a decrease in quality of life, poor quality of sleep, and decreased fear of COVID infection. Cynicism, professional effectiveness, anxiety, depression, and sleep quality explained up to 87.8% of the variance in quality of life. Conclusions: Caregivers' decreased quality of life during the pandemic was explained by their levels of burnout, anxiety, and depression throughout the 6-month period.

Caregiving for Dementia Patients during the Coronavirus Pandemic.

The coronavirus pandemic has had a global impact on both mental and physical health. Caregiving has become more difficult during this time due to the quick spread of this respiratory disease, dread of the unknown, congested hospitals, and many restrictions, particularly for people with multiple comorbidities. We aimed to assess the impact of this pandemic on a group of caregivers of patients with dementia and their needs during this time. The study's findings indicate that females assumed the role of the caregiver more often than men (88.5% of the participants) and scored lower on the life quality scale. The most often issue encountered during the pandemic was difficulty in accessing health care facilities (36%). Participants with a higher education level scored better in the physical (24.67, p = 0.01 and 24.48, p = 0.01) and mental health (20.67, p = 0.002; 19,82, p = 0.008) domains of the life quality test. The fear of COVID questionnaire showed a low level of concern in the category of participants with a high education level. Overall, this pandemic emphasizes the importance of social interaction and the possibilities to improve health care services through telemedicine. Caregivers could benefit from socialization and support programs as well as the early detection of affective disorders.
