High-risk Cytomegalovirus in Heart Transplant: How Can We Improve?

Background: Cytomegalovirus (CMV) infection is associated with worse outcomes after heart transplant (HT). CMV mismatch (donor positive, recipient negative serology, D+/R-) increases the risk of infection. Guidelines recommend 3 to 6 months of antiviral prophylaxis in these patients.

Navigating the Neurosurgery Match Process: Insights from the National Resident Matching Program - Program Director Surveys.

Objective: Neurosurgery is one of the most competitive specialties, and navigating the match process is often challenging for aspiring applicants. Here, we analyze insights from the National Resident Matching Program Director Surveys, illustrating evolving trends in applicant selection for interviews and for the ranking process, and providing a comparison with other specialties.

Methods: We evaluated 7 surveys administered from 2012 to 2022.

Megahertz-rate background-oriented schlieren tomography in post-detonation blasts.

The understanding and predictive modeling of explosive blasts require advanced experimental diagnostics that can provide information on local state variables with high spatiotemporal resolution. Current datasets are predominantly based on idealized spherically symmetric explosive charges and point-probe measurements, although practical charges typically involve multidimensional spatial structures and complex shock-flow interactions. This work introduces megahertz-rate background-oriented schlieren tomography to resolve transient, three-dimensional density fields, as found in an explosive blast, without symmetry assumptions.

[Differences among renin-angiotensin system inhibitor drugs in prognosis of hypertense patients with COVID-19].

Introduction: Concerns have been raised about Renin-angiotensin system inhibitors (RASi) in patients with COVID-19. Although recent trials have proved its security, evidence regarding intrinsic differences between RASi is lacking, especially in patients with arterial hypertension. Our objective was to analyse the prognosis of hypertense patients who received angiotensin converting enzyme inhibitors (ACEi) or angiotensin-2 receptor blockers (ARBs) and were hospitalized due to COVID-19.

[Cardiovascular disease after COVID-19 infection in elderly patients. Results of annual follow-up of a cohort of survivors].

Introduction: Although the effects of SARS-CoV-2 infection on the cardiovascular system is well known in the acute phase, the cardiovascular impact of the elderly population surviving COVID-19 respiratory infection after 1 year of follow-up has not been sufficiently studied.

Methods: Observational registry of 240 elderly patients (75 years or older), consecutively admitted for COVID-19 respiratory infection and survivors of the same, between March 1 and April 30, 2020, at the Hospital General Universitario de Ciudad Real. The incidence of major cardiovascular events [MACE] (cardiovascular death [CD], acute coronary syndrome [ACS], cerebrovascular disease [CVD], venous thromboembolic disease [VTE] and heart failure [HF]) was prospectively analysed.

Fecal Indicator Bacteria Data to Characterize Drinking Water Quality in Low-Resource Settings: Summary of Current Practices and Recommendations for Improving Validity.

Fecal indicator bacteria (FIB) values are widely used to assess microbial contamination in drinking water and to advance the modeling of infectious disease risks. The membrane filtration (MF) testing technique for FIB is widely adapted for use in low- and middle-income countries (LMICs). We conducted a systematic literature review on the use of MF-based FIB data in LMICs and summarized statistical methods from 172 articles.

Comparative analysis between the use of renin-angiotensin system antagonists and clinical outcomes of hospitalized patients with COVID-19 respiratory infection.

Introduction: Hypertension has been associated with worse outcomes in patients with COVID-19 infection, so concerns have been raised about the possibility that inhibitors of the renin-angiotensin system (RAS) could influence the prognosis of these patients.

Methods: This is an observational study of 921 consecutive patients admitted with COVID-19 respiratory infection to Hospital General Universitario Ciudad Real from March 1 to April 30, 2020. Following data were collected including patient demographic information, medical history, clinical characteristics, laboratory data, therapeutic interventions during the hospitalization and clinical outcomes.

Impact of Treatment with Renin-Angiotensin System Inhibitors on Clinical Outcomes in Hypertensive Patients Hospitalized with COVID-19.

Introduction: Concerns have been raised about the possible harmfulness of angiotensin-converter enzyme inhibitors (ACEi) and aldosterone receptor blockers (ARB) in patients with COVID-19. However, few data from a European population have been published, especially from hypertensive patients.

Aim: To study the association between ACEi or ARB treatments and major adverse outcomes during hospitalisation in COVID-19 patients.
