Objective To analyze the published studies that investigated the physical function, activities of daily living and health-related quality of life in COVID-19 survivors. Design Systematic review. Methods We searched MEDLINE/PubMed, Scopus, SciELO, and Cochrane Library for studies that evaluated the physical function, activities of daily living and health-related quality of life after COVID-19 from the earliest date available to July 2021. Two independent reviewers screened and selected the studies. The Newcastle Ottawa Scale was used to evaluate methodological quality. Results We included 35 studies in this systematic review. Of the 35 studies included, 28 were cohort, and 7 cross-sectional studies The studies demonstrated that COVID-19 survivors had reduced levels of physical function, activities of daily living, and health-related quality of life. Furthermore, incomplete recovery of physical function, and performance in activities of daily living were observed 1 to 6 months post-infection. Discussion Physical disability and reduction in health-related quality of life is a common condition in post-COVID-19 and impairments may persist up to 1 to 6 months. Researchers and clinicians can use these findings to understand the potential disabilities and rehabilitation needs of people recovering from the COVID-19.

Gestational hypothyroidism is a prevalent disorder in pregnant women. We aimed to investigate the impact of experimental gestational hypothyroidism (EGH) on cardiovascular and autonomic nervous systems (ANS) in the offspring of rats. EGH was induced with methimazole (MMI) 0.02% in drinking water from day 9 of gestation until birth. Sixty day old offspring from MMI-treated dams (OMTD, n=13) or water-treated dams (OWTD, n=13) had femoral arteries surgically assessed for the measurements of heart rate (HR), mean (MAP), systolic (SAP) and diastolic arterial pressure (DAP), and spontaneous baroreflex sensitivity (BRS). To investigate the balance of ANS, we established the high (HF) and low frequency (LF) bands of pulse interval (PI) and LF band of SAP spectrum. OMTD had increased MAP (130.2 ± 2.0 vs 108.8 ± 3.0 mmHg, p<0.001), SAP (157.3 ± 2.9 vs 135.7 ± 4.5mm Hg, p<0.001) and DAP (109.7 ± 1.9 vs 88.4 ± 2.6 mmHg, p<0.001) when compared to OWTD, and had lower HR (355.1 ± 8.9 vs 386.8 ± 9.2 bpm, p<0.05). After spectral analysis of PI and SAP, only LF band of SAP spectrum was higher (7.2 ± 0.8 vs 4.0 ± 0.6 mmHg(2), p<0.01) in OMTD under spontaneous condition. Despite bradycardia, EGH promotes spontaneous hypertension in 60 day old offspring, probably due to increased sympathetic modulation of vessels, which is suggested by the higher LF of SAP. These findings suggest a critical role of maternal THs in the development of fetal cardiovascular and autonomic nervous systems.
