Influenza infection has been identified as a triggering or exacerbating factor for cardiovascular events. To analyse the effect of influenza vaccination on cardiovascular disease, a systematic search of studies published between 2009-2019 was conducted. All the studies that evaluated the effect of vaccination against influenza on cardiovascular events and their outcome were considered. ⋯ These studies show a protective effect of the influenza vaccine on the development of cardiovascular events (myocardial infarction, cerebrovascular accidents, atrial fibrillation, and heart failure) and on the worsening of these conditions. Furthermore, the data showed that vaccinated patients have a lower risk of death from cardiovascular pathologies. Influenza vaccination is therefore an effective measure in the prevention of cardiovascular diseases both in patients with established cardiovascular disease and in the population without previous coronary pathology.

Case Reports Multicenter Study Observational Study
Skin lesions in children during the first wave of the SARS-CoV-2 pandemic.
Cutaneous manifestations have been included in COVID-19 patients' clinical spectrum. Our objective was to determine the association between skin lesions in children and SARS-CoV-2 infection, analyzing others possible infectious/autoimmune etiologies. ⋯ In our study, the presence of chilblains-like and/or vesicular lesions were significantly related to SARS-CoV-2 previous contact.

There is great interest in better characterizing patients with heart failure (HF) with preserved ejection fraction (HF-PEF). The objective of this study is to determine the prevalence, progression over time and to describe the clinical and epidemiological characteristics of patients with HF-PEF. ⋯ Sixty percent of patients in the RICA registry have preserved ejection fraction. These patients have a higher comorbidity burden and a worse functional status, but lower mortality compared with HF-REF patients.

Bendopnea is a symptom described in heart failure (HF) that is related to short-term prognosis; however, its frequency and characteristics in respiratory diseases such as OSAS is still unknown. This study was carried out to evaluate the prevalence of bendopnea in patients with severe obstructive sleep apnea syndrome (OSAS) METHODS: We conducted a study of 95 patients attending a sleep disorders unit with severe OSAS. Bendopnea was considered when shortness of breath occurred within 30s of bending forward. ⋯ One-third of patients with severe OSAS present bendopnea. This symptom is related to a higher prevalence of comorbidities (HF, obesity and other respiratory diseases). It is also related to a higher CT90.
