AI Article Synopsis

  • * They detected a specific mutation (c.779 C>T) in the HNF1A gene, which contributed to varying symptoms among family members.
  • * Treatment included the medication Gliclazide for blood glucose control and regular genetic counseling, which improved the mental health of affected individuals.

Article Abstract

Background: To analyze the gene mutation and mental disorder of a Chinese ketosis-prone diabetes (KPD) family, and to make a precise diagnosis and give a treatment for them.

Methods: We studied a Chinese family with a clinical diagnosis of maturity-onset diabetes of the young (MODY). The clinical data and the blood samples were collected. The promotor and coding regions inclusive intron exon boundaries of the HNF1A, HNF4A were detected by polymerase chain reaction (PCR) and direct sequencing. The missense mutation was also analyzed by bioinformatics. Genetic counseling was performed twice a month to relieve the mental disorder of the persons.

Results: The missense mutation c.779 C>T (p.T260M) in exon4 of HNF1A gene was detected, and the symptom heterogenicity among persons in this family were found. All the members were retreated with Gliclazide and stopped to use other medicine, the blood glucose of them were well controlled. We also performed an active genetic counseling to them and the mental disorder of the proband's sister was relieved.

Conclusions: A missense mutation of HNF1A gene was first found in Chinese ketosis-prone MODY family with manifestations heterogenicity among the persons. Sulphonylureas medicine and genetic counseling are efficiency ways to treat MODY 3 and its' mental disorder respectively.

Preterm births constitute a major public health issue and a chronic, cross-generational condition globally. Psychological and biological factors interact in a way that women from low socio-economic status (SES) are disproportionally affected by preterm delivery and at increased risk for the development of perinatal mental health problems. Low SES constitutes one of the most evident contributors to poor neurodevelopment of preterm infants.

Major depressive disorder (MDD) is usually considered associate with immune inflammation and synaptic injury within specific brain regions. However, the molecular mechanisms underlying the neural deterioration resulting in depression remain unclear. Here, it is found that miR-204-5p is markedly downregulated in the ventromedial prefrontal cortex (vmPFC) in a chronic unpredictable mild stress (CUMS) induce rat model of depression.

Background: Despite the rising prevalence of common mental symptoms, information is scarce on how health workers make sense of symptoms of mental disorders and perceive a link with inadequate water, sanitation, and hygiene (WASH) as work stressors to understand causation and produce useful knowledge for policy and professionals. Therefore, this study aimed to explore how health workers perceive the link between inadequate WASH and common mental symptoms (CMSs) at hospitals in central and southern Ethiopian regions.

Methods: We used an interpretive and descriptive phenomenological design guided by theoretical frameworks.

This retrospective study aims to assess the adjunctive efficacy of warm needle moxibustion and gua sha care in the treatment of eszopiclone tablets on sleep quality and psychological stress in insomnia patients. Data of 138 insomnia patients from Gansu Baoshihua hospital between January and December 2022 were collected. Patients were bifurcated into 2 groups: those solely treated with eszopiclone (n = 71) and those administered a combined regimen of eszopiclone, warm needle moxibustion, and gua sha (n = 67).
