Objective Prolonged severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection has been reported in immunocompromised patients, as they poorly develop antibodies against SARS-CoV-2. We conducted a clinical trial to determine the efficacy of Imdevimab/Casirivimab (Imde/Casiri), an anti-viral monoclonal antibody (mAb), for prolonged infection at our institution. Methods Nine patients with hematological malignancies (six with malignant lymphoma and three with multiple myeloma) in our institution presented with coronavirus disease 2019 caused by SARS-CoV-2 omicron variants (one, five, and one with BA.2, BA.5, and BF.7, respectively; two undetermined). ⋯ Results Within seven days of infusion, viral RNA was undetectable in five of the nine cases. Because all seven viruses isolated from patients whose viral RNA became undetectable showed low or no sensitivity to this monoclonal antibody cocktail, the disappearance of viral RNA in these cases may not be attributable to the antibody cocktail. Conclusion It may be worth considering the use of monoclonal antibodies that show some activity against these virus variants to treat persistent SARS-CoV-2 infection in immunocompromised patients.

The effect of COVID-19 infection on pulmonary function is unknown. ⋯ Although there is no significant difference in PFT measurements from 3 to 6 months in COVID-19 patients, systemic steroid therapy may have a beneficial effect on respiratory function in COVID-19 patients.

Piloting an aircraft is a complex multitasking activity that involves managing information in a nonautomatic way and generates a high workload (psychological, cognitive, and physical) for the pilot. The excess of these demands can result in decreased performance and may impair flight safety. Heart rate variability (HRV) has been used in recent studies as a method to investigate operator's workload in complex environments. This measure can assess the stress and recovery ability of the autonomic nervous system. However, a better understanding of flight influence on the pilot's autonomic modulation is necessary. Therefore, this scoping review aims to systematically map the studies related to changes in the autonomic modulation in military pilots during flight, in order to characterize their workload at different times and flight profiles. ⋯ This scoping review provided insight into the influence of flight on autonomic modulation in military pilots. Some key themes were highlighted: Increased sympathetic activity during flight, sensibility of different domains of HRV to flight demands, and autonomic changes during recovery time. Future research efforts may allow us to enhance the understanding of pilot's workload limits and to elucidate the optimal postflight recovery time.

COVID-19 and Neurodevelopmental Delays in Early Childhood: A Longitudinal Analysis of Developmental Outcomes in Korean Children.
This study employed a longitudinal analysis to evaluate the association between the coronavirus disease 2019 pandemic and neurodevelopment by analyzing over 1.8 million children from the Korean Developmental Screening Test for Infants and Children included in South Korea's National Health Screening Program. We compared the developmental outcomes in five age groups-9-17 months, 18-29 months, 30-41 months, 42-53 months, and 54-65 months-between the pre-pandemic (2018-2019) and pandemic (2020-2021) periods. ⋯ Children from socioeconomically disadvantaged backgrounds faced higher risks across all domains. These findings highlight the need for targeted interventions and continuous monitoring to support the developmental needs of children affected by pandemic-related disruptions.

Observational Study
Lung Ultrasound Efficacy in Monitoring Post-SARS-CoV-2 Pneumonia and Inflammatory Biomarkers in Pediatric Patients.
Background and Objectives: Recognizing the crucial gaps in our understanding of pediatric pneumonia post-SARS-CoV-2 infection, this study aimed to assess the relationship between Pediatric Pneumonia Ultrasound Scores (PedPne) and inflammatory biomarkers. The primary objective of this study is to evaluate the predictive value of PedPne in comparison with inflammatory biomarkers (IL-6 and dNLR) for the development of pneumonia in pediatric patients following SARS-CoV-2 infection. Materials and Methods: This longitudinal observational study collected data from pediatric patients diagnosed with pneumonia after an acute SARS-CoV2 infection. ⋯ Regression analysis further highlighted the strong predictive power of these markers, with IL-6 showing a fourfold increase in pneumonia risk (HR = 4.25, CI: 2.07-9.53, p < 0.001), dNLR indicating more than a twofold increase (HR = 2.53, CI: 1.19-6.97, p = 0.006), and PedPne score associated with more than a doubling of the risk (HR = 2.60, CI: 1.33-5.18, p < 0.001). Conclusions: The study conclusively demonstrated that both PedPne ultrasound scores and specific inflammatory biomarkers such as dNLR and IL-6 are significant predictors of pneumonia development in pediatric patients post-COVID-19 infection. These findings advocate for the integration of these biomarkers in routine clinical assessments to enhance the diagnostic accuracy and management of pneumonia in children following SARS-CoV-2 infection.
