Flight Hours and Depression in Flight Attendants During the COVID-19 Pandemic.
Aerosp Med Hum Perform
November 2024
Introduction: Flight attendants are constantly exposed to high-stress environments that could lead to the development of depression. The COVID-19 pandemic brought out new risk factors that could affect flight attendants' mental health, such as reduced flight hours and fear of the disease itself, which other studies have shown was associated with depression. We aimed to find out whether reduced flight hours, fear of COVID-19, and other factors were associated with depression in flight attendants during the COVID-19 pandemic.

HLA-G, an important immune-checkpoint (IC) molecule that exerts inhibitory signalling on immune effector cells, has been suggested to represent a key player in regulating the immune response to Severe Acute Respiratory Syndrome Coronavirus Type 2 (SARS-CoV-2). Since specific single-nucleotide polymorphisms (SNP) in the HLA-G 3'untranslated region (UTR), which arrange as haplotypes, are crucial for the regulation of HLA-G expression, we analysed the contribution of these genetic variants as host factors in SARS-CoV-2 infection during acute and post-acute phases. HLA-G gene polymorphisms in the 3'UTR were investigated by sequencing in an unvaccinated Coronavirus Disease 2019 (COVID-19) cohort during acute SARS-CoV-2 infection (N = 505) and in the post-acute phase (N = 253).

Fatigue risk assessment for flight crews flying across time zones in different directions to the east or west during the COVID-19 pandemic in China.

Air Force Medical Center, Air Force Medical University, Beijing, 100142, China.
Background: There is a lack of data support and scientific validation of the Exemption Approach policy for responding to the COVID-19 pandemic, in terms of protecting the health of flight crews and meeting the requirements for passenger and cargo transportation in emergencies, in terms of its safety and the circumstances that contribute to pilots' symptoms of jet lag and the risk of fatigue.
Methods: To assess pilots' sleep issues related to jet lag symptoms and fatigue, this study evaluated an example of risk management for flight crews on flights across time zones during the COVID-19 pandemic. To evaluate the crew's sleep status, variations in sleep index changes between before and after the flights, variations in sleepiness levels, and data on sleep indexes recorded by ActiGraph bracelets were collected from 146 crew members before and after flights eastward or westward across time zones.
Temporal variations in QTc interval during and after COVID-19 infection: a retrospective study.

Department of Cardiology, The Second Affiliated Hospital of Wannan Medical College, 10# Kangfu road, Wuhu, Anhui Province, 241000, China.
Objective: The aim of this study was to investigate the dynamic changes in QTc interval duration among patients with COVID-19 infection before, during, and after infection, in order to assess the short- and potential long-term impact of COVID-19 on cardiac electrophysiology.
Methods: A retrospective analysis was conducted on 303 inpatients diagnosed with COVID-19 who visited a tertiary Grade A hospital in China between August 2022 and December 2023. Inclusion criteria required patients to have at least two electrocardiogram (ECG) recordings at three specific time points: before COVID-19 infection, during acute infection, and after recovery (more than one month post-infection).
