Serum samples from children were collected at birth (month 0) and at 2, 7, 18, 24, 36, and 48 months of age to test for EV-A71 NT antibody titers using an enzyme-linked immunosorbent assay (ELISA)-based microneutralization test. The seroprotection rate (NT antibody ≥116) in children at months 0, 2, 7, 18, 24, 36, and 48 was 81.0%, 60.0%, 9.0%, 10.0%, 13.0%, 17.0%, and 37.1%, respectively. The seroprotection rate was lowest at month 7 due to waning of the maternal antibody and the immunity of children increased with increasing age. At 48 months of age, less than 40% of children were seroprotected. Children at the age of 6 months should be considered a primary target for vaccination.

The red reflex examination (RRE) and visual acuity testing (VA) is a mandatory part of the examination during the well-child visits (WCV) in primary health care centres of the public system of health in Chile. The eye examination is aimed at the early detection of severe eye diseases in children, such as retinoblastoma, congenital cataracts, and amblyopia. The knowledge and difficulties experienced by health workers in primary care health centres for evaluating the red reflex during WCV in Chile is unknown.

A survey was performed in primary community health centres of XXX Santiago de Chile.

The WCV were mainly performed by physicians (45.2%) and nurses (35.8%). Only 34% of health workers performed the red reflex test, and 42.3% checked VA during the WCV. The main reasons for not doing it include the lack of direct ophthalmoscopes and VA charts (55.2% and 43.9%, respectively) at their centres, and not having the knowledge or skills (29.3% and 22%, respectively) to properly perform these clinical tests.

In this series, the eye examination of children attending WCV was unfrequently performed. A better implementation of the health centres and training of the health workers are needed in order to improve the access and quality of the paediatric eye examination in primary health care institutions in Chile.

Continuous positive airway pressure (CPAP) is an important therapeutic tool in COVID-19 acute respiratory distress syndrome (ARDS) since it improves oxygenation, reduces respiratory rate and can prevent intubation and intensive care unit (ICU) admission. CPAP during pronation has seldom been described and never during sedation.

Case series.

High dependency unit of San Carlo University Hospital (Potenza, Italy).

Eleven consecutive patients with COVID-19 ARDS.

Helmet CPAP in prone position after failing a CPAP trial in the supine position.

Data collection at baseline and then after 24, 48 and 72h of pronation. We measured PaO

/FIO

, pH, lactate, PaCO

, SpO

, respiratory rate and the status of the patients at 28-day follow up.

Patients were treated with helmet CPAP for a mean±SD of 7±2.7 days. Prone positioning was feasible in all patients, but in 7 of them dexmedetomidine improved comfort. PaO

/FIO

improved from 107.5±20.8 before starting pronation to 244.4±106.2 after 72h (p<.001). We also observed a significantly increase in Sp0

from 90.6±2.3 to 96±3.1 (p<.001) and a decrease in respiratory rate from 27.6±4.3 to 20.1±4.7 (p=.004). No difference was observed in PaCO

or pH. At 28 days two patients died after ICU admission, one was discharged in the main ward after ICU admission and eight were discharged home after being successfully managed outside the ICU.

Helmet CPAP during pronation was feasible and safe in COVID-19 ARDS managed outside the ICU and sedation with dexmedetomidine safely improved comfort. We recorded an increase in PaO

/FIO

, SpO

and a reduction in respiratory rate.

Thoracic ultrasound has been shown to be useful in the diagnosis of COVID-19 pulmonary involvement. Several scores for quantifying the degree of involvement have been described, although there is no evidence to show that they have any capacity for predicting unfavorable progress.

Prospective cohort study of patients hospitalized for COVID-19. Belnacasan The sample was stratified according to clinical course, and patients requiring invasive or non-invasive respiratory support were classified as having unfavorable progress. Biomarkers were analyzed at admission and on the same day that thoracic ultrasound was performed. Prognostic scales were also determined at admission. The ultrasound score was obtained in 8 or 14 areas, depending on the patient's ability to sit.

We included 44 patients, 13 (29,5%) of whom subsequently needed ventilatory support. Eight areas were explored in all patients and 14 areas in 35 (79.5%). The most affected areas were the posterior lower lobes. Significant differences were found between the 2groups on the SOFA and quick SOFA multidimensional scales, and PCR and LDH on the same day as thoracic ultrasound, and the ultrasound scores. The best area under the ROC curve (AUC) was obtained with the 14-area score, with a result of 0.88 (95% CI 0.75-0.99). Its sensitivity and specificity for a cut-off score of 13.5 were 100% and 61.5%, respectively.

The use of scores to quantify lung involvement measured by thoracic ultrasound provides useful information, facilitating risk stratification in patients hospitalized with COVID-19.

To explore the association between hearing loss and social frailty in a sample of Spanish older adults recruited from primary health care network.

Cross-sectional study on a sample of 445 non-institutionalized adults aged 65 or more years (190 men and 255 women), recruited from primary care centers in Spain. Three self-reported hearing impairment questions were used to assess hearing loss. Social frailty was deemed to exist when the person presented two or more of the following conditions living alone, absence of a person to provide help, infrequent contact with family, infrequent contact with friends, lack of confident and lack of help for daily activities in the last 3 months. To study the association between hearing loss and social frailty we used logistic regression models adjusted for potential confounders, including physical frailty.

The mean age of participants was 76.2 years (77.5 years for women). More than half of the participants (54.4%) reported hearing loss and the frequency of social frailty was 23.
