Global Prevalence of COVID-19-Associated Mucormycosis (CAM): Living Systematic Review and Meta-Analysis

Mucormycosis, a secondary fungal infection, gained much attention in the ongoing COVID-19 pandemic. This deadly infection has a high all-cause mortality rate and imposes a significant economic, epidemiological, and humanistic burden on the patients and healthcare system. Evidence from the published epidemiological studies showed the varying prevalence of COVID-19-associated mucormycosis (CAM). This study aims to compute the pooled prevalence of CAM and other associated clinical outcomes. MEDLINE, Embase, Cochrane COVID-19 Study Register, and WHO COVID-19 databases were scanned to retrieve the relevant articles until August 2021. All studies reporting the prevalence of mucormycosis among COVID-19 patients were eligible for inclusion. Two investigators independently screened the articles against the selection criteria, extracted the data, and performed the quality assessment using the JBI tool. The pooled prevalence of CAM was the primary outcome, and the pooled prevalence of diabetes, steroid exposure, and the mortality rate were the secondary outcomes of interest. Comprehensive Meta-Analysis software version 2 was used for performing the meta-analysis. This meta-analysis comprised six studies with a pooled sample size of 52,916 COVID-19 patients with a mean age of 62.12 ± 9.69 years. The mean duration of mucormycosis onset was 14.59 ± 6.88 days after the COVID-19 diagnosis. The pooled prevalence of CAM (seven cases per 1000 patients) was 50 times higher than the highest recorded background of mucormycosis (0.14 cases per 1000 patients). A high mortality rate was found among CAM patients with a pooled prevalence rate of 29.6% (95% CI: 17.2–45.9%). Optimal glycemic control and the judicious use of steroids should be the approach for tackling rising CAM cases.

Living with hypertrophic cardiomyopathy: the patient’s perspective

Hypertrophic cardiomyopathy (HCM) is a complex disease characterized by thickening of the cardiac muscle. Common symptoms include chest pain, shortness of breath, palpitations, fatigue and syncope (fainting), which are often confused for other conditions. Clinical treatment focuses on the relief of symptoms with medical therapies, which provide adequate to more variable symptomatic relief. Patients may experience more severe complications that require surgical intervention, such as implantable cardioverter-defibrillator therapy or septal myectomy. Despite the potential impact on quality of life, the humanistic burden of HCM is not well established. Here, we present four patient testimonials that highlight challenges faced by patients and clinicians in diagnosing HCM and managing symptoms. These testimonials provide valuable information on the spectrum and expression of HCM across generations. Such testimonials can better inform disease diagnosis and monitoring, maximizing quality of life and improving disease outcome.
