ReviewDiastolic dysfunction for nephrologists: diagnosis at the point of care.
Cardiovascular diseases are important causes of morbidity and mortality in the course of chronic kidney disease (CKD). Diastolic dysfunction (DD) may progress with the clinical manifestation of heart failure, known as heart failure with preserved ejection fraction, a condition that precedes systolic dysfunction. The early identification of DD by echocardiography at the point-of-care before the appearance of symptoms and signs of pulmonary congestion and the implementation of appropriate treatment can improve the prognosis of CKD. This review article briefly addresses DD in kidney disease and presents a practical approach to the echocardiographic diagnosis of DD at the point of care.

ReviewUses and limits of the clinical laboratory in the COVID-19 pandemic: a didactic review.
The world is currently experiencing an unprecedented pandemic of a new disease, the coronavirus disease (COVID-19), which has unusual clinical and immunological presentations. This is especially true regarding the choice and interpretation of laboratory test results. In this review, we have provided didactic information for physicians on the current concepts and practical guidance regarding COVID-19.

Randomized Controlled TrialProtective effect of dexmedetomidine on perioperative myocardial injury in patients with Stanford type-A aortic dissection.
To investigate the protective effect and mechanism of dexmedetomidine (Dex) on perioperative myocardial injury in patients with Stanford type-A aortic dissection (AD). ⋯ Dex treatment may alleviate perioperative myocardial injury in patients with Stanford type-A AD by resisting inflammatory response and oxidative stress.

Case ReportsProbable vertical transmission identified within six hours of life.
We present the case of 33 weeks + weeks pregnant patient (G1P0), with proven COVID-19 infection by RT-PCR and, at admission, she presented with a dry cough and "tiredness when talking,". Chest computed tomography was performed, which showed the presence of attenuations with ground glass opacification and bilateral consolidations. She then had a cesarean section because of maternal respiratory decompensation. ⋯ The newborn was transferred to the neonatal ICU of the same hospital in ambient air and maintained in respiratory and contact isolation. RT-PCR was collected for SARS-COV-2 at 6 h of life, which was positive. Faced with the knowledge gap on vertical transmission, RT-PCR for SARS-COV-2 at 6 h of life gives cause for concern, thus representing the possibility of vertical transmission by SARS-COV-2, although additional investigations are required.

Prevalence of hot flashes in women of 40 to 65 years of age with metabolic syndrome.
Hot flashes have a negative impact on the quality of life of women during the menopausal transition and thereafter. The progressive reduction in gonadal estrogen levels associated with aging promotes an accumulation of abdominal fat, dyslipidemia, and arterial hypertension, all of which are components of metabolic syndrome (MetS). The objective of the present study was to estimate the prevalence of hot flashes and evaluate their relationship with MetS in women ≥ 40 years of age. ⋯ In women ≥ 40 years of age, hot flashes are highly prevalent and appear to be associated with MetS.
