Pizzol et al. (1) performed a systematic review and meta-analysis to examine the available evidence and provide pooled estimates for prevalence of ejaculatory dysfunction (EjD) and erectile dysfunction in relation to all cancer sites and identify characteristics associated with EjD in cancer patients

An umbrella review of observational studies with meta analyses for any physical and/or mental comorbidities associated with eye disease was performed in Trott et al. (2). The results showed highly suggestive evidence for associations between diabetic retinopathy and cardiovascular disease, open angle glaucoma and diabetes, myopia and open angle glaucoma, as well as suggestive evidence for associations between cataract and all-cause mortality and gout, depression and diabetic retinopathy, and hypertension and migraine for open angle glaucoma.

The COVID-19 pandemic has led to health care practitioners having to adapt their working conditions and environments, as well as restricted access to hospital eye services. Pardhan and Vaughan (3) reviewed the literature surrounding eye care and the impact of the COVID-19 pandemic on patients and eye care practitioners.

Jacob et al. (4) aimed to investigate the association between sarcopenia and mild cognitive impairment (MCI) among community-dwelling adults aged ≥65 years from six low- and middle-income countries (LMICs). They found a positive association between sarcopenia and MCI in this sample of older adults living in LMICs.

Sujan et al. (5) ran a cross-sectional survey to measure diabetes related worries and their associations with social support and lifestyle amongst people with diabetes during the COVID-19 pandemic. They found that diabetes related worries were strongly associated with a lack of social support.
