The noninvasive prenatal test (NIPT) for genetic screening has been adopted globally as an alternative to first-trimester and quad screening due to its high sensitivity and specificity. NIPT involves detecting and processing foreign fetal DNA in maternal circulation to screen for fetal aneuploidy. An incidental consequence of this process is the detection of foreign tumor cell DNA in maternal circulation in otherwise asymptomatic patients.

Background: COVID-19 disease results in disparate responses between individuals and has led to the emergence of long coronavirus disease (Long-COVID), characterised by persistent and cyclical symptomology. To understand the complexity of Long-COVID, the importance of symptom surveillance and prospective longitudinal studies is evident.

Methods: A 9-month longitudinal prospective cohort study was conducted within Scotland (n=287), using a mobile app to determine the proportion of recovered individuals and those with persistent symptoms and common symptoms, and associations with gender and age.

  • While some studies showed significant improvement in symptoms for PRP-treated patients, results were inconsistent, indicating the need for more research to clarify PRP's effectiveness and consider other factors like follow-up times and patient conditions.

Health-related quality of life (HRQoL) is inversely associated with all-cause mortality in older adults and may be improved with physical activity and exercise training. The objective of this umbrella review was to determine the impact of physical activity and exercise training on HRQoL in younger-old (average age ≤ 75 years) and older-old (average age > 75 years) adults. Our umbrella review (CRD42023481145) included 39 systematic reviews (21/39 with meta-analysis) including 113 unique individual studies of 13391 unique participants.

Health-related quality of life (HRQoL) is a patient-perceived measure of physical, social, and emotional health. Acquired brain injury (ABI) occurs due to damage to the brain after birth. Individuals with an ABI typically present with reduced HRQoL and require additional support to maintain their HRQoL.
