The respiratory syncytial virus (RSV) fusion (F) protein undergoes two furin-cleavage events to become fusion competent, resulting in the release of a twenty-seven amino acid peptide (p27). Recent studies indicate that the p27 region of the F protein was an immunodominant antigen in young children. In this study, we evaluated the kinetics of the serum antibody response to the p27 peptide following natural RSV reinfection in adults. Nineteen healthy adults under sixty-five years of age were enrolled during the 2018-2019 RSV season in Houston, TX. Blood was collected at three study visits and RSV infection status was defined by changes in neutralizing antibody resulting in three groups uninfected (n = 12), acutely infected (n = 4), and recently infected (n = 3). Serum IgG and IgA antibodies against RSV/A and RSV/B p27 peptides were measured by enzyme-linked immunosorbent assays, and serum p27-like antibodies were detected by a p27 competitive antibody assay. Anti-p27 antibodies were detected in all subjects at of the RSV/A and RSV/B p27 antibody response may enhance our understanding of the intracellular processing of the F protein.Costa Rica is an upper middle-income country in Central America with a vigorous public health system. We have studied the number of cases, hospitalizations, and deaths due to pertussis from 1961 to 2018, in relation to vaccine coverage. Following the introduction of the fourth and fifth doses of DTP (booster doses) in 1973 there was a marked reduction of reported pertussis. In 2002 pertussis surveillance and laboratory diagnosis were improved. In 2007, Tdap post-partum immunization was introduced and then switched to intrapartum Tdap immunization in 2011. Of these two strategies post-partum vaccination seemed to have a greater effect in decreasing hospitalizations and deaths, nevertheless, since 2011 there has been only 4 infant deaths due to pertussis.

The 21st Century Cures Act requires that institutions release all electronic health information (EHI) to patients immediately. We aimed to understand patient and clinician attitudes toward the immediate release of EHI to patients.

Patients and clinicians representing distinct specialties at a single academic medical center completed a survey to assess attitudes toward the immediate release of results. Differences between patient and clinician responses were compared using chi-square and student's t-test for categorical and continuous variables, respectively. A two-sided significance level of 0.05 was used for all statistical tests.

69 clinicians and 57 patients completed the survey. Both patients (89.7%) and clinicians (80.6%) agreed or strongly agreed-here after referred to as agreed, that providing patients with access to their health information is necessary in delivering high-quality care. However, 62.7% of clinicians agreed that results released immediately would be more confusing than helpful, whediate release of results is controversial, especially among clinicians. The discrepancy between patient and clinician perceptions underlines the importance of setting expectations about the communication of results. Additionally, our results emphasize the need to implement strategies to help improve patient comprehension, decrease patient distress and improve clinician workflows.Three-dimensional (3D) culture of organoids from primary cells (wild type) or tumoroids from tumor cells, is used to study the physiological mechanisms in vivo, in order to model normal or tumor tissues more accurately than conventional two-dimensional (2D) culture. The features of this 3D culture, such as the three-dimensional structure, the self-renewal capacity and differentiation are preserved and appropriate to cancer study since their cellular characteristics are very similar to in vivo models. Here, we summarize the recent advances in the rapidly evolving field of organoids and their applications to cancer biology, clinical research and personalized medicine.Nitrous oxide (N2O) is used since the eighteenth century as an anesthetic and analgesic but also for recreational use. If the labelled uses of N2O and their modalities are nowadays perfectly framed, the misuse of N2O takes very alarming proportions among teenagers and young adults. This misuse is the cause of acute (hypoxia, barotrauma, burns, neuropsychiatric disorders) and chronic complications if repeated (myeloneuropathy, anemia, thrombosis, inhalant use disorder). The main mechanism of the latter is mainly related to a functional deficit in vitamin B12 induced by N2O. The management of acute complications is symptomatic. The management of chronic complications is based on vitamin B12 supplementation. The best biomarker of chronic N2O exposure is the elevation of the plasmatic level of methylmalonic acid. In all cases of recreational misuses, addiction treatment is necessary to prevent complications or their worsening by providing information in order to stop consumption.

Exposure to general anaesthesia in children may be related to deficits in certain areas of cognition. It is unclear if these deficits could be measured in the immediate postoperative period in young children. The goal of the current study was to evaluate the trajectory of cognitive function in the domains of processing speed, working memory, and fine motor skills amongst children aged 2.5-6 yr who underwent general anaesthesia for elective surgery.

Children who were scheduled to receive general anaesthesia for surgery were recruited for assessment of cognitive function at three times preoperatively, 1-2 weeks postoperatively, and 3 months postoperatively. Assessments included processing speed, working memory, and fine motor skills. To assess longitudinal changes in the cognitive outcomes, linear mixed models were built with visit number included as a categorical variable and subject-specific random intercepts.

Sixty-one children (33 girls [54%]) enrolled in the study. Twenty-three children (38%) had received general anaesthesia previously. Significant improvements in picture memory, cancellation, and the processing speed composite were found at Visit 2. The improvement in cancellation and processing speed composite remained significant at Visit 3. Statistically significant improvement in Mullen fine motor score was noticed at Visit 3 compared with Visit 1. The pattern of results did not depend upon prior anaesthesia exposure.

General anaesthesia for elective surgery in young children was not associated with declines in working memory, processing speed, and fine motor skills in the first 3 months postoperatively, including in children with prior exposure to anaesthesia.

From events in resource-poor developing countries, through richly funded military conflicts, to the most equipped of developed nations, the provision of rapid medical care to the severely injured during major incidents and mass casualty events has been a priority for healthcare providers. This is often under the most difficult of circumstances.1,2 Whilst mass casualty events are a persistent global challenge, it is clear in developed countries that patients and their families demand and expect a high standard of care from their rescuers, that this care should be delivered rapidly, and this should be of the highest quality possible.3 Whilst there is respect afforded to those who 'run towards danger' during a high-threat situation, first responders are subjected to a high degree of scrutiny for their actions, even when the circumstances they are presented with are considered to be extraordinary.4 Likewise, even for those who are catastrophically injured beyond salvage, society expects the response to be dignified, calculated, and thorough.3.Preparedness for mass casualty events is essential at local, national, and global levels. Much more needs to be done by all stakeholders to avoid unnecessary morbidity and mortality despite the challenges that COVID-19 continues to present. In this editorial, we highlight the challenges and solutions for mass casualty incident preparations.Patient self-inflicted lung injury may be associated with worse clinical outcomes and higher mortality. Patient-ventilator asynchrony is associated with increased ventilator days and mortality, and it has been hypothesised as one of the important mechanisms leading to patient self-inflicted lung injury. However, given the observational nature of the key studies in the field so far, the hypothesis that patient-ventilator asynchrony causes patient self-inflicted lung injury has not been supported by evidence yet. Wittenstein and colleagues present a novel approach that enables controlling patient-ventilator asynchrony in a pig model of acute lung injury, to investigate the patient-ventilator asynchrony and patient self-inflicted lung injury causality. Their results suggest that increased patient-ventilator asynchrony associated with poor clinical outcomes reported in observational trials could be a marker, rather than a cause of patient self-inflicted lung injury. These findings on their own are not sufficient to justify a greater tolerance of patient-ventilator asynchrony amongst clinicians, a change for which further experimental work and clinical evidence is needed.Artificial intelligence (AI) has the potential to identify treatable phenotypes, optimise ventilation strategies, and provide clinical decision support for patients who require mechanical ventilation. Gallifant and colleagues performed a systematic review to identify studies using AI to solve a diverse range of clinical problems in the ventilated patient. They identify 95 studies, the majority of which were reported in the last 5 yr. learn more Their findings indicate that the majority of studies have significant methodological bias and are a long way from deployment.

To report telemedicine's feasibility and satisfaction rates for treating patients with pectus carinatum using a dynamic compressor system. We analyzed treatment adherence in comparison with the previous, non-pandemic year.

Retrospective analysis including patients with pectus carinatum under treatment with a dynamic compressor system using telemedicine at the chest wall centers from two hospitals, private and public, between April and July 2020. A free video conference platform for teleconsultations was employed. We evaluated the incidence of pectus cases with telemedicine, the number of dynamic compressor system prescriptions, the number of patients in the correction phase, and the number who ended treatment. To assess adherence, we compared our cohort with an in-person cohort during the same time frame of the previous, non-pandemic year. In addition, we performed a patient satisfaction survey comprising questions related to socioeconomic status, the likeability of telemedicine, simplicity of modification of the system, and desire to continue with telepectus after the pandemic.
