RESUMO
OBJECTIVES: To describe the prenatal neuroimaging spectrum of rhombencephalosynapsis (RES) and criteria for its classification according to the severity of vermian anomaly. METHODS: In this multicenter retrospective study of fetuses with RES between 2002 and 2020, the medical records and brain ultrasound and magnetic resonance images were evaluated comprehensively to determine the severity of the vermian anomaly and the presence of associated brain findings. RES was classified, according to the pattern of vermian agenesis and the extent of the fusion of the hemispheres, as complete RES (complete absence of the vermis) or partial RES (further classified according to the part of the vermis that was missing and, consequently, the region of hemispheric fusion, as anterior, posterior, severe or mixed RES). Findings were compared between cases with complete and those with partial RES. RESULTS: Included in the study were 62 fetuses with a gestational age ranging between 12 and 37 weeks. Most had complete absence of the vermis (complete RES, 77.4% of cases), a 'round-shaped' cerebellum on axial views (72.6%) and a transverse cerebellar diameter (TCD) < 3rd centile (87.1%). Among the 22.6% of cases with partial RES, 6.5% were classified as severe partial, 6.5% as partial anterior, 8.1% as partial mixed and 1.6% as partial posterior. Half of these cases presented with normal or nearly normal cerebellar morphology and 28.5% had a TCD within the normal limits. Infratentorially, the fourth ventricle was abnormal in 88.7% of cases overall, and anomalies of the midbrain and pons were frequent (93.5% and 77.4%, respectively). Ventriculomegaly was observed in 80.6% of all cases, being more severe in cases with complete RES than in those with partial RES, with high rates of parenchymal and septal disruption. CONCLUSIONS: This study provides prenatal neuroimaging criteria for the diagnosis and classification of RES, and identification of related features, using ultrasound and magnetic resonance imaging. According to our findings, a diagnosis of RES should be considered in fetuses with a small TCD (severe cerebellar hypoplasia) and/or a round-shaped cerebellum on axial views, during the second or third trimester, especially when associated with ventriculomegaly. Partial RES is more common than previously thought, but presents an extreme diagnostic challenge, especially in cases with normal or nearly-normal cerebellar morphobiometric features. © 2021 International Society of Ultrasound in Obstetrics and Gynecology.

BACKGROUND AND OBJECTIVE: Eosinophilic esophagitis (EoE) is an increasingly prevalent chronic inflammatory disease of the esophagus with an immunoallergic etiology. Few studies have been published on EoE in children and adolescents. The objective of this study was to analyze the demographic, clinical, serologic, endoscopic-histologic, and atopic characteristics of pediatric patients with EoE and to identify atopic and digestive comorbidities. METHODS: We conducted a prospective observational study in children and adolescents (<16 years) assessed in a specialized multidisciplinary EoE unit in a tertiary referral hospital in a central region of Spain between 2011 and 2015. RESULTS: Thirty-five patients were included in the study. Twenty-eight (80%) were male. The mean age was 9.6 years, 83% were atopic, and 28% reported a family history of atopy. The most common symptom was dysphagia (51%). Eosinophilia was detected in the blood of 60% of patients. Eosinophil cationic protein and total IgE were elevated in 88% and 77% of patients, respectively. The most frequent endoscopic finding was linear grooves (57%). Skin tests with aeroallergens were positive in 82% of patients (pollen 62% and food 60%). The main atopic comorbidities were asthma (48%) and rhinoconjunctivitis (37%). Digestive diseases were more often associated with gastritis and Helicobacter pylori infection (17%). CONCLUSIONS: Our results are similar to those previously reported. EoE is more common in boys and in individuals with a history of atopy and sensitization to airborne allergens and food. These results support the consideration of EoE as an atopic disease and underline the important role of allergists in early diagnosis and treatment.

BACKGROUND: Eosinophilic esophagitis (EoE) is a chronic inflammatory emerging disease of the oesophagus with immunoallergic aetiology. The allergens involved have not been clearly defined and may depend on the exposure of the population to aeroallergens or food antigens. MATERIALS AND METHODS: Patients diagnosed with EoE between 2006 and 2011 were referred to our Allergy Section. Patch and skin prick tests (SPT) with aeroallergens and foods were performed, and total and specific IgE levels, eosinophil cationic protein levels and eosinophil count were determined. RESULTS: 43 patients were included. 36 (83.7%) were atopic. 29 patients presented choking, 19 dysphagia, 9 food impaction with urgent endoscopy, 4 chest pain, 1 isolated vomiting and 1 epigastric pain. 22 had two or more symptoms. The mean duration of symptoms was 3.73 years. Concomitant allergic diseases included rhinoconjunctivitis and/or asthma (31 patients), IgE food allergy (21 patients) and atopic dermatitis (3 patients). 32 (74%) were sensitized to aeroallergens, of which 90% were sensitized to pollens; 23 (54%) showed positive tests to foods and 12 of them (52%) to lipid transfer proteins (LTP). Of the 29 pollen-allergic patients, 15 (52%) were sensitized to plant foods and 10 (34.4%) to LTP. CONCLUSIONS: Our findings support those reported in the literature: the disease is more common in men aged 30-40 years with at least a three-year history of symptoms of esophageal dysfunction, sensitized to pollens, the predominant aeroallergen in our area, but also to plant foods or panallergens. These results increase the evidence for an immunoallergic aetiology and can help us in the early diagnosis of EoE.

Excess weight and obesity have high prevalence rates globally and are associated with significant morbidity and mortality rates. In the wake of the COVID-19 pandemic, telehealth emerged as an effective tool for promoting healthy behaviours in the management of chronic conditions. This study employed a three-month quasi-experimental design with pre- and post-intervention measurements, assessing the progress of 82 adults assigned either to an intervention group (IG) or a control group (CG). A total of 66 participants completed the study, with 33 in each group. The IG had access to a telehealth-based platform providing educational content on healthy lifestyle habits and were followed up both in-person and remotely. The CG were monitored as usual, i.e., at their primary care nurses' discretion. The IG exhibited a statistically significant reduction in weight, BMI, and abdominal circumference, along with improved adherence to a heart-healthy diet, specifically the Mediterranean diet, and higher levels of physical activity. The nurse-led intervention (Care4US+), utilising telehealth from primary care, has proven effective in enhancing healthy behaviours and reducing cardiovascular risk factors.

Arthrospira maxima is a source of phycobiliproteins with different nutraceutical properties, e.g. antioxidant and anti-inflammatory activities. The current study was aimed at the elaboration, characterization, and evaluation of the anti-inflammatory effect of the phycobiliprotein nanoparticles extracted from Arthrospira maxima. Previously freeze-dried phycobiliproteins were milled by high-energy ball milling until reaching a nanometric size (optimal time: 4 h). Microscopy techniques were used for the characterization of the size and morphology of phycobiliproteins nanoparticles. Additionally, a spectroscopic study evidenced that nanosized reduction induced an increase in the chemical functional groups associated with its anti-inflammatory activity that was tested in a murine model, showing an immediate inflammatory effect. The novelty and importance of this contribution was to demonstrate that high energy ball milling is an emerging and green technology that can produce phycobiliprotein nanoparticles on a large-scale, without the use of organic solvents, to test their nutraceutical properties in a biological model by intragastric administration.

OBJECTIVE: Since the beginning of the pandemic, it has become necessary to know the epidemiological evolution of SARS-CoV-2. Therefore, this study aims to describe the characteristics of the casuistry of COVID-19 in health and social-health workers in the health area of A Coruña and Cee during the first epidemic wave, as well as to determine the association between the clinical profile and/or its duration and the condition of RT-PCR repositivization. MATERIALS AND METHODS: During the study period, 210 cases belonging to healthcare and social-healthcare workers from the healthcare area of A Coruña and Cee were diagnosed. A descriptive analysis of sociodemographic factors was carried out, as well as the search for association between the clinical picture and the duration of detection of a positive RT-PCR. RESULTS: The most affected categories were nursing (33.3%) and nursing assistants (16.2%). The mean time taken for cases to become RT-PCR negative was 18.3±9.1 days, with a median of 17. It was observed that 26 cases (13.8%) had a positive result in a subsequent RT-PCR, without meeting criteria for reinfection. The existence of skin manifestations and arthralgias was associated with repositivization after adjusting for age and sex (OR=4.6 and OR=6.5, respectively). CONCLUSIONS: In healthcare professionals diagnosed with COVID-19 during the first wave, symptoms such as dyspnea, skin manifestations and arthralgias led to RT-PCR repositivization after a previous negative result and without meeting criteria for reinfection.
