A New Portable Device for Non-invasive Ventilatory Support

Acute respiratory failure is a medical emergency rapidly leading to death, if not timely treated. Prompt Continuous Positive Airway Pressure (CPAP) improves patient outcomes. However, pre-hospital CPAP is currently limited to healthcare providers due to the absence of easy-to-use and immediate devices specifically designed for the non-medical population. The efficacy and usability of a new portable CPAP device will be assessed. This device is specifically designed for potential use in out-of-hospital scenarios involving acute respiratory failure. The evaluation will focus not only on the performance of the device but also on its easiness of use.

How OMT Benefits Newly Diagnosed Patients With Respiratory Illness When Given Alongside Other Standard Care.

This study is to see Osteopathic Manipulative Therapy, or OMT, can aid in treating patients being seen for respiratory illness and associated symptoms. The hypothesis is that the addition of OMT therapy, alongside other standard care (such as a medication), can help lessen patient symptoms sooner than just other treatment alone, and the duration of the condition will shorten as well.

Caffeine as an Adjuvant Therapy for Late Preterm Infants With Respiratory Distress

Use of caffeine citrate in late-preterm infants with respiratory distress is questionable. Oliphant and colleagues found in a recently published study that caffeine therapy use in late-preterm infants at a loading dose of 20 and 40 mg/kg and maintenance dose of 10 and 20 mg/kg/day reduces the incidence of intermittent hypoxia events by 61 and 67% respectively. The investigators hypothesized that caffeine will improve respiratory drive, prevent apnea, shorten the hospital stay and improve arousal state in late preterm infants. The investigators aim to study the effect of caffeine citrate on late preterm babies as regard duration of respiratory support, duration of hospital stay, respiratory morbidity, incidence and frequency of apnea.

Prospective Observational Study to Characterize Patients Treated at Internal Medicine Clinics

Patients referred to internal medicine wards are becoming increasingly complex and fragile. Despite deep knowledge of their specific disorders, steps are required to improve overall management of their acute and chronic conditions. The main objective of the study is to identify demographic, clinical, laboratory and radiological markers of disease severity and activity in patients with diseases treated at general medicine wards (respiratory disease, immune-mediated disease, sepsis, metabolic disease, rare disease, frailty, pregnancy pathology) in order to improve their diagnosis, monitoring and treatment processes.

The Effect of Vitamin E Supplementation on Hospital Stay Duration in Non-cyanotic Heart Disease Children With Lower Respiratory Tract Infections

Congenital heart disease can lead to serious health issues, particularly an increased risk of infections, specifically respiratory infections. Lower respiratory tract infections are the fifth leading cause of death globally. Also considered a significant cause of morbidity and mortality among children with congenital heart disease. In Egypt, it is estimated that 10% of deaths in children under the age of 5 years are probably caused by lower respiratory tract infections and other acute respiratory infections. common non-cyanotic CHD like Ventricular septal defect predispose to bronchopneumonia. Hemodynamically significant congenital heart disease with pulmonary congestion increases the risk of lower respiratory tract infections and hospitalizations. This relies on several modifiable risk factors, including low socioeconomic status, poor diet, overcrowding, prematurity, male gender, and exposure to secondhand smoke. Micronutrients play a crucial role in strengthening the immune system. Many Studies have shown that when children are supplemented with various micronutrients, they experience fewer episodes of acute respiratory infections, and the duration and severity of these infections are reduced. Vitamin E is essential for immune system function and may lower disease risk by enhancing immune responses. It protects neurons and respiratory mucosa from oxidative damage and has been linked to a reduced incidence of asthma and inflammation, potentially safeguarding young children from atopy and wheezing. There are no available studies in our locality about the effect of vitamin E supplementation on the length of hospital stay for non-cyanotic cardiac patients with lower respiratory tract infections.

The State of Nebulizer Therapy in Russian Federation

It is known that the inhalation (nebulizer) use of drugs is of great importance in the intensive care of patients with acute and chronic respiratory failure of various origins. Searching PubMed data for the last 5 years (2017-2022) for the keywords "nebulizer therapy" revealed 533 publications, and "mesh nebulizer therapy" - only 25 sources. During the same period, the national database (E-Library) has 75 publications for the keywords "nebulizer therapy", and 4 sources for "mesh nebulizer therapy". It should be noted that almost all publications are devoted to the use of nebulizers for specific diseases and pathological syndromes. There are no works evaluating the adherence of specialists, systemic indications and actually used methods. The aim of trial is to study the current state of the use of nebulizer therapy in medical organizations and identify ways to improve its effectiveness This study is planned to be carried out using a questionnaire using a database based on the Internet electronic survey form.

Frequent Standardized Oral Care Using Human Milk in the Neonatal Intensive Care Unit

Premature infants are susceptible to complications related to infrequent and non-standardized oral care. Although the benefits of frequent standardized oral care are known to reduce oral dysbiosis (increased level of potentially pathogenic bacteria) and its associated complications in critically ill adults leading to established evidence-based guidelines, no such information exists for VLBW infants. The proposed study will prospectively follow 168 VLBW infants for 4 weeks following birth.

Extremely Preterm Respiratory Outcome Cohort

This study examines the respiratory outcomes of preterm infants born at gestational ages less than 29 weeks, spanning from birth to 24 months corrected age. It delves into the intricacies of respiratory function impairment attributable to diverse factors, such as respiratory distress syndrome, bronchopulmonary dysplasia, postnatal corticosteroids, ventilatory support, as well as nutritional aspect during NICU stay. Furthermore, it scrutinizes the incidence of chronic respiratory diseases stemming from these conditions, assessing their long-term impact on respiratory prognosis post-discharge. In addition to respiratory aspects, the research extends its focus to the growth and developmental outcomes of preterm infants. By synthesizing these multifaceted elements, the study aspires to enhance current treatments and preventative measures for respiratory conditions in preterm infants.

Urban Transformations and Health: the Case of TransMiCable in Bogotá

Cable cars are means of transportation with urban mobility benefits for vulnerable populations living in areas with geographic barriers. Despite their popularity, there is no evidence of cable cars' potential health effects. TransMicable, located in "Ciudad Bolivar", Bogota, Colombia will open in late-2018 presenting an unprecedented opportunity to assess the health impacts and accessibility improvements. The investigators aim is to assess the effect of theTransMiCable implementation on social determinants of health (social capital, employment, crime, transport, microenvironment pollution, built environment), healthy behaviors (leisure and transport physical activity) and health outcomes (health-related quality of life, respiratory diseases and homicides). The investigators are conducting a controlled quasi-experimental pre-post study with six elements: 1) The co-construction of a conceptual framework using a causal loop diagram with stakeholders of multiple sectors. 2) A (non-intervention - intervention) quantitative study of social capital, community participation, travel time, costs, demand, modal choice, physical activity and health-related quality of life using repeated in-person questionnaire, anthropometric measurements and physical activity using accelerometers. 3) A transport trajectory study in a subsample of the population of the quantitative study using a mobile application to track journeys. 4) A subsample of environment evaluations 5) Our Voice in the Neighborhood qualitative study to address the potential change in perceptions of the neighborhood using Citizen Science "by the people" involving the community and local public and private stakeholders and 6) A Secondary-data analysis of Crime and Respiratory diseases using time trends from official surveillance systems for homicides and acute respiratory diseases. The investigators' main hypothesis are 1) There is an increase in the Social Capital and Quality of life indicators in the TransMicable target area after the implementation when compared to other neighborhoods without TransMiCable. 2) There is a significant decrease in travel time and cost for trips to downtown Bogota and an increase in the total number of trips for residents of "Ciudad Bolivar" neighborhoods with TransMiCable, after the implementation of TransMiCable when compared to other neighborhoods without TransMiCable in the locality of "San Cristobal". 3) There is a significant shift in modal choice for the resident of "Ciudad Bolivar" from informal transport service to the TransMiCable system with a positive association in terms of proximity to TransMiCable stations. 4) Most TransMiCable users are former informal bus transit and formal bus feeder users. While most users will access TransMiCable by walking, some living further from stations will take informal transport services to access to TransMiCable. 5) There is a reduction in the microenvironment pollution around the target area of TransMiCable when compared to the control area. 6) There is a change in the perception of the neighborhood for residents of the target area of TransMiCable when compared to the control area. 7) There is a significant decrease in the prevalence of homicides and acute respiratory diseases in the area of the TransMiCable implementation in comparison to the control area without TransMiCable. The results of this study will allow us to understand baseline dynamics, while, in the long-term, allowing us to assess the changes in travel and health behaviors.

REVIVe: Frailty, Rehabilitation, and Outcomes in Critically Ill Adult and Pediatric Survivors of COVID-19 or ARI

Background: Many adults and some children with COVID-19 or acute respiratory infection become critically ill and need advanced life support in the Intensive Care Unit (ICU). Frailty is a medical condition of reduced function and health. Adults with frailty have a lower chance of surviving critical illness. The investigators are still learning about critically ill adults with COVID-19 or acute respiratory infection, and do not have much information on how frailty affects outcomes in critically ill children, with or without COVID-19 or acute respiratory infection. Rehabilitation can help survivors of COVID-19 or acute respiratory infection by improving strength and improve quality of life (QOL). Objectives: The main goal of this research study is to see if patients with frailty have a lower chance of surviving COVID-19 or acute respiratory infection critical illness and more health problems after survival than patients without frailty. The investigators will also study the types of rehabilitation received by patients with COVID-19 or acute respiratory infection. Methods: The investigators will include adults and children with COVID-19 or acute respiratory infection who are admitted to the ICUs that participate in the study. The investigators will gather data about each patient, including before and during their illness. Outcomes: The investigators will collect level of frailty, function, and types of therapy, or rehabilitation received by patients. In adults, the investigators are most interested in learning if frailty influences mortality, or death. In children, the investigators are most interested in whether children with COVID-19 or acute respiratory infection critical illness are more likely to develop frailty. The investigators will also study post-hospital discharge location in survivors (e.g., home, rehabilitation). Relevance: The COVID-19 pandemic is a global public health crisis. It is critical to understand how COVID-19 and other acute respiratory infection critical illness affects groups of people who are at higher risk, and the impact on outcomes that are important to patients, like functioning and QOL. The results will help policy makers plan post-hospital services for survivors, help healthcare workers understand the importance of rehabilitation practice for patients with COVID-19 or acute respiratory infection, and help researchers develop treatments to improve QOL after COVID-19 or acute respiratory infection.

The goal of this observational study is to evaluate the implementation of the INSPIRE program and to plan actions for the preparation, coordination, monitoring, diagnosis, and treatment of respiratory diseases in the municipality of Botucatu. Methods: Individuals with respiratory symptoms from the municipality of Botucatu, aged 18 or older, will be invited to participate in the study, and socioeconomic data, as well as information on sex, gender, race, nutritional risk, frailty, tobacco exposure, and its derivatives, will be collected. For those with exposure, screening and treatment for respiratory diseases will be offered through assessment of pulmonary function, body composition, respiratory and peripheral muscle strength. Additionally, individuals over 40 years old with tobacco exposure equal to or greater than 30 pack-years will be offered low-dose chest CT screening for lung cancer. Expected results: To identify and assess vulnerable groups that face difficulties in accessing respiratory healthcare, as well as implement specific strategies for the treatment of respiratory diseases and tobacco control for these groups. To ensure equitable access to respiratory health for the entire population at risk due to smoking. Moreover, through proactive and reactive risk reduction actions implemented by the program, to intervene in distinct groups and other regions.

Smart Watch Insights for Prevention of Exacerbations and Enhance Rehabilitation - Movement Study

Aims of the study: 1. To deliver a scalable wellbeing programme to the local population of Imperial College Healthcare NHS Trust, focusing on movement. 2. To describe the natural history of long-term conditions using digital data from a smartwatch. 3. To identify digital information that is routinely collected by a smart watch that can be used to predict outcomes in patients with long term conditions. 4. To identify factors that determine whether participants engage with and improve in a movement programme. Adult patients who are registered to the Imperial NHS Care Information Exchange (CIE), an NHS patient-facing electronic health record, are eligible to participate in the study. Participants will receive a smart watch for self-monitoring of their movement and wellbeing and be asked to wear the device as much as possible. They will be asked to download a smartphone application called Connected Life, which displays movement and information on heart rate, breathing and oxygen levels to both the participant and the research team (digital data). Participants will receive secure login details for the Connected Life application from the research team, to ensure data privacy. The research team will look at participants' health records, and attempt to identify associations between the digital data and clinical information. This will allow the research team to identify digital data that predicts the onset and natural history of long term conditions, which may potentially allow for earlier diagnosis for future patients. The primary outcome of the study is the identification of trends in movement based on step-count data recorded by the smartwatch.

Sleepiz One+ vs. Capnography and Electrocardiography

Respiratory Rate (RR) and heart rate (HR) are vital signs crucial for assessing a patient's overall health, providing insights into various conditions and stressors. Effective management of chronic diseases relies on detecting pathological changes early, with RR being among the most sensitive predictors of patient deterioration. Therefore, vigilant monitoring of RR and HR is vital for improving patient outcomes. The primary aim of this study is to provide a thorough comparison of the performance of Sleepiz One+ algorithms and end-tidal carbon dioxide measurement (EtCO2) Capnography for measuring respiration rate and electrocardiography (ECG) for measuring heart rate, in healthy adults and patients suffering from chronic conditions (e.g., hypertension, Chronic Obstructive Pulmonary Disease (COPD), asthma, diabetes), at rest in a clinical setting when the data is acquired with the new hardware version. Additionally, the investigators will evaluate the performance of RR estimation against the thoracic effort belt and the HR against the pulse oximetry.
