Post-COVID-19 Epidemic: Allostatic Load among Medical and Nonmedical Workers in China.

Background: As the fight against the COVID-19 epidemic continues, medical workers may have allostatic load.

Objective: During the reopening of society, medical and nonmedical workers were compared in terms of allostatic load.

Methods: An online study was performed; 3,590 Chinese subjects were analyzed.

Mental Health and Psychosocial Problems of Medical Health Workers during the COVID-19 Epidemic in China.

Objective: We explored whether medical health workers had more psychosocial problems than nonmedical health workers during the COVID-19 outbreak.

Methods: An online survey was run from February 19 to March 6, 2020; a total of 2,182 Chinese subjects participated. Mental health variables were assessed via the Insomnia Severity Index (ISI), the Symptom Check List-revised (SCL-90-R), and the Patient Health Questionnaire-4 (PHQ-4), which included a 2-item anxiety scale and a 2-item depression scale (PHQ-2).

Protocol on transcranial alternating current stimulation for the treatment of major depressive disorder: a randomized controlled trial.

Methods: This is an 8-week, double-blind, randomized, placebo-controlled study.

Effect of Transcranial Alternating Current Stimulation for the Treatment of Chronic Insomnia: A Randomized, Double-Blind, Parallel-Group, Placebo-Controlled Clinical Trial.

Background: Not all adults with chronic insomnia respond to the recommended therapeutic options of cognitive behavioral therapy and approved hypnotic drugs. Transcranial alternating current stimulation (tACS) may offer a novel potential treatment modality for insomnia.

Objectives: This study aimed to examine the efficacy and safety of tACS for treating adult patients with chronic insomnia.

[Relationship between three neuropsychological tests and cerebral glucose metabolism in Alzheimer's disease].

Objective: To study the relationship between the scores of 3 neuropsychological scales: MMSE, extended scale of dementia (ESD) and Blessed dementia scale (BDS) and cerebral glucose metabolism in Alzheimer's disease (AD) indicated by positron emission tomography (PET).

Methods: Brain scanning was performed with SIEMENS ECAT 47 PET scanner among 21 AD patients, aged 60 - 83 (10 mild, 6 moderate, and 5 severe), and 15 healthy persons, aged 57 - 73. The ratio of mean radioactivity of cerebral lobe to that of cerebellum as semi-quantitative parameters was used to evaluate the cerebral glucose metabolism.
