Pressure injuries are a health problem of special concern for older adults, and different scales are used to assess the risk of developing these ulcers. We assessed the prevalence of residents at high risk of pressure injuries using a Norton scale and examined its relationships with the most important risk factors in a large sample of Italian nursing homes (NHs). ⋯ The prevalence of NH residents at high risk of pressure injuries was very high using the Norton scale, but the percentage of residents who develop these ulcers is lower. Female NH residents with advanced age, dementia, and a history of cerebrovascular disease should be carefully monitored.

COVID-19 has varied clinical manifestations, from asymptomatic to severe cases, and conjunctivitis is one of them, but sometimes a lone initial symptom is found to be present. The aim of this study was to identify the prevalence of conjunctivitis as the first symptom in COVID-19 patients in a primary healthcare unit. ⋯ Conjunctivitis is a symptom of COVID-19 and may be the first sign of the infection, until the onset of the classical manifestations; such patients may continue to be a viral reservoir. Physicians should not miss unilateral conjunctivitis as it can be the only presenting complaint of COVID-19 during the initial phase, which might worsen if undetected and can aid in the spread of the contagion.

Although acetaminophen is one of the most widely used over-the-counter drugs, the mechanisms by which this classical drug exerts analgesic, hepatotoxic, and nephrotoxic effects remain unclear. We hypothesized that acetaminophen might act on cellular membranes of nerves, liver, and kidneys. In order to verify this hypothesis, we studied the interactivity of acetaminophen with biomimetic lipid bilayer membranes by comparing with structurally related phenacetin. ⋯ In comparison with phenacetin, lipid composition-dependent membrane interactivity of acetaminophen could be related to nephrotoxicity but not to analgesic activity and hepatotoxicity.

Thyroid dysfunction is a common cause of atrial fibrillation (AF). Incidence of AF is high in patients with both expressed and subclinical hyperthyroidism. The aim of our study was to determine the incidence and predictors of new onset atrial fibrillation (NOAF) in euthyroid patients undergoing thyroid surgery. ⋯ Incidence of NOAF during thyroid surgery is similar to the other type of surgery, if the values of thyroid hormones are normal.

While severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) primarily affects lung tissue, it may cause direct or indirect damage to the cardiovascular system, and permanent damage may occur. Arterial stiffness is an early indicator of cardiovascular disease risk. The aim of our study was to establish the potential effects of SARS-CoV-2 on the vascular system evaluated by transthoracic echocardiographic examination. ⋯ SARS-CoV-2 may cause reduced or impaired aortic elasticity parameters linked to impaired arterial wall function in COVID-19 survivors compared with controls.
