We aimed to identified clinical settings of renal transplant patients with COVID-19 Material and methods: In this retrospective study, we included kidney transplant inpatients with laboratory confirmed COVID-19 who had been discharged or had died by October 1, 2020. Characteristics of the patients, basal and last outpatient biochemical parameters of the patients were recorded. Discontinuation or dosage reduction of immunosuppressives and other treatment information were documented. 20 patients were included in this study, of whom 18 were discharged and 2 died in hospital. The mean duration of hospitalization and follow-up were 9.7 ± 6.4 day and 4.5 ± 2.0 months, respectively.14 (70%) were male, mean age was 48.0±10.3 years. At admission, all had immunosuppression withdrawn and were started on methylprednisolone 16 mg/day (50%) or dexamethasone (50%). Tacrolimus/m-TOR inhibitors were reduced by 50% and all antimetabolites were discontinued. Hemodialysis was needed for 10% of patients. Acute kidney injury was detected in 25% of the patients. With respect to hospitalization time and complications, there was no significant difference between dexamethasone users and those who did not (p>0.05).The discontinued immunosupressives were resumed within 2-4 weeks after discharge according to severity of disease. No re-hospitalization or acute rejection was detected during the follow-up of the patients. Renal transplant patients are considered a high risk group for COVID-19. It can be said that discontinuation or reduction dosages of immunosuppressives may be an effective and safe in kidney transplant patients.

Aim: Although the transforearm approach is considered a safe and effective option for percutaneous coronary intervention, the different characteristics of the radial and ulnar arteries deserve attention. This study aimed to evaluate radial (RA) and ulnar artery (UA) diameter and blood flow parameters changes after catheterization. Material and method: A total of 328 patients were enrolled. Their artery (171 RA and 157 UA) diameter and flow parameters [peak systolic velocity (PSV), end-diastolic volume (EDV) and pulsatility index (PI)] were evaluated before and after catheterisation. Results: After RA catheterization, the diameters and PSV decreased in the RA (from 2.71±0.66 to 2.47±0.51, p=0.007; from 44.7±8.3 to 33.9±9.5, p=0.021) and increased in the UA (from 2.49±0.83 to 2.59±0.58, p=0.033; from 48.3±11.9 to 59.6±11.0, p

Resumo Fundamento: As matrizes metaloproteinases (MMPs) podem afetar o volume extracelular (VEC) e seus compartimentos, e isso pode oferecer informações mais detalhadas sobre o mecanismo de remodelação adversa (RA) do ventrículo esquerdo (VE) após o infarto agudo do miocárdio (IM). Objetivos: Investigar o papel que as alterações (Δ) nos compartimentos de VEC (volume matriz (MVi) e volume celular (CVi)) desempenham no desenvolvimento de RA após o IM, e sua relação com as expressões de MMP-2. Métodos: Um total de noventa [...] Resumo Fundamento: As matrizes metaloproteinases (MMPs) podem afetar o volume extracelular (VEC) e seus compartimentos, e isso pode oferecer informações mais detalhadas sobre o mecanismo de remodelação adversa (RA) do ventrículo esquerdo (VE) após o infarto agudo do miocárdio (IM).
