Basic sonographic examination of the fetal brain at 11-13 weeks' gestation: Rationale for a simple and reliable four-step technique.

The widespread incorporation of first-trimester scanning between 11 and 13 weeks' gestation has shifted from the screening of chromosomal abnormalities, mainly by measuring nuchal translucency thickness and visualization of the nasal bone, to a more detailed study of the fetal anatomy leading to early detection of several structural congenital anomalies. This goal can be improved by the routine and focused sonographic assessment of specific anatomic planes and the identification of distinctive landmarks that can help disclosing a particular, non-evident condition. In this article we present the basis for a basic, early examination of the fetal brain during screening using a four-step technique, which can be readily incorporated during the first-trimester scan.

Circulating citric acid cycle metabolites and risk of cardiovascular disease in the PREDIMED study.

Background And Aim: Plasma citric acid cycle (CAC) metabolites might be likely related to cardiovascular disease (CVD). However, studies assessing the longitudinal associations between circulating CAC-related metabolites and CVD risk are lacking. The aim of this study was to evaluate the association of baseline and 1-year levels of plasma CAC-related metabolites with CVD incidence (a composite of myocardial infarction, stroke or cardiovascular death), and their interaction with Mediterranean diet interventions.

[Epidemiological study on the impact of influenza vaccination on the clinical course of patients with COVID-19 and co-infection by both viruses in Gran Canaria, Spain].

Objective: To analyze the frequency of influenza and SARS-CoV-2 co-infections, as well as the differences in the course of disease (risk of mortality, hospital and intensive care admissions) in patients infected with the SARS-CoV-2 virus in relation to flu vaccination status in the 2021-2022 season.

Methods: Population-based observational retrospective study in a cohort of 19,850 patients diagnosed with COVID-19 between June 1, 2021 and February 28, 2022 on the island of Gran Canaria.

Results: A total of 1,789 patients (9%) diagnosed with COVID-19 had received flu vaccinations.

Safety perception in the operating environment: The nurses' perspective versus that of the surgeons.

Background: Adverse effects due to surgery occur in 25% of patients, and the patient safety perception seems to differ between nurses and surgeons in the operating room (OR). This difference can be attributed to lack of communication. However, our hospital has not conducted any studies on patient safety climate (PSC) in the OR.

Effects of Ozone Treatment on Health-Related Quality of Life and Toxicity Induced by Radiotherapy and Chemotherapy in Symptomatic Cancer Survivors.

(1) Background: The continuous improvement in cancer treatment has led to improvement in patients’ survival and a subsequent increase in the number of cancer survivors living with adverse side effects of cancer treatments, sometimes with a high and adverse impact on their health-related quality of life (HRQOL). Side effects of cancer treatments are frequently associated with chronic status of oxidative stress, inflammation, and/or ischemia. The potential for ozone treatment to modulate those processes and improve some of those adverse effects has previously been described.

Short-term evaluation of renal markers in overweight adult cats.

Background: Obesity has been proposed as an independently risk factor for chronic kidney disease (CKD) in people, but its role in feline kidney function is unknown.

Objective: Obesity has been proposed as an independent risk factor for chronic kidney disease (CKD) in people, but its role in feline kidney function is unknown. This study prospectively evaluated the effect of overweight on the concentration of symmetric dimethylarginine (SDMA) and creatinine in a cohort of healthy cats.

Effects of HIV infection and/or malaria on maternal and neonatal health in a high-prevalence setting.

Objective: HIV infection and malaria have been associated with different complications during pregnancy and delivery. HIV-positive pregnant women are at increased risk for all adverse outcomes of malaria during pregnancy. The main objective was to analyse the obstetric and perinatal consequences of malaria, HIV infection and HIV/malaria co-infection in pregnant women and newborns, which has been less well evaluated.

Asymptomatic endometrial thickening in postmenopausal women: predictor of malignant pathology?

It is not standardised what is the endometrial thickness that discriminates between normal and potentially malignant. The objective of this study was to determine the endometrial thickness cut-off point from which the risk of endometrial cancer (EC) increases in asymptomatic postmenopausal women; and to evaluate the risk factors linked to malignant endometrial pathology as well as other associated ultrasound findings.This was a retrospective observational study that included hysteroscopies performed at the Hospital Materno-Infantil on 267 asymptomatic menopausal women with an increase in endometrial thickness (AET) >5 mm, from 2015 to 2019.

Recommendations on the Management of Patients with Immune Thrombocytopenia (ITP) in the Context of SARS-CoV-2 Infection and Vaccination: Consensus Guidelines from a Spanish ITP Expert Group.

Primary immune thrombocytopenia (ITP) is an acquired autoimmune disease with highly variable presentation, characteristics, and clinical course. Thrombocytopenia is a common complication of many viral infections, including SARS-CoV-2. In addition, both de novo ITP and exacerbation of ITP after vaccination against SARS-CoV-2 have been reported.

Active approach in delivery room and survival of infants born between 22 and 26 gestational weeks are increasing in Spain.

Aim: To describe the trends in the delivery room approach and survival of extremely premature infants over the past two decades.

Methods: Time-series analysis of infants included in the Spanish SEN1500 network from 2004 to 2019. Patients born from 22 + 0 to 26 + 6 weeks were included.

Pemetrexed and Platinum Plus Pembrolizumab in Patients With Metastatic Nonsquamous NSCLC by Tumor Burden at Baseline: A Post Hoc Efficacy Analysis of KEYNOTE-189.

Introduction: The aim of this study was to evaluate the efficacy of pemetrexed and platinum plus pembrolizumab by baseline tumor burden.

Methods: A total of 616 patients in the intention-to-treat population of the KEYNOTE-189 study were included in this analysis. Baseline tumor burden subgroups were identified on the basis of extent of distant metastasis (M1a versus M1b), median number (≤3 versus >3) of organ systems with lesions, or symptom severity score of patient-reported lung cancer-associated symptoms (≤median versus >median).

Cost minimization analysis of brolucizumab in the treatment of neovascular age-related macular degeneration.

Introduction: Brolucizumab is a novel anti-vascular endothelial growth factor (anti-VEGF) drug administered in a fixed regimen of 8 or 12 weeks which, in the HAWK and HARRIER studies, was shown not to be inferior to aflibercept with respect to the best corrected visual acuity, with a less burdensome treatment regimen. The aim of the analysis was to compare the direct healthcare costs of both anti-VEGF as a treatment in patients with neovascular age-related macular degeneration.

Material And Methods: A cost minimization analysis was performed under a 25-year time horizon and considering the drug costs, administration, follow-up tests, and management of adverse events.
