Previous literature has suggested physical exercise may improve cognitive impairments and mitigate depressive symptoms. However, few studies examined the impact of resistance exercise intervention on cognition and depression in older Chinese Americans. The purpose of this pilot study was to assess the effects of resistance exercise training on cognitive performance and depressive symptoms among community-dwelling older Chinese Americans.
View Article and Find Full Text PDFElectronic cigarettes (e-cigarettes) and hookah smoking have gained tremendous popularity over the past decade. With the constantly evolving e-cigarette market and potential impact of the COVID-19 pandemic on users of these tobacco products, research is needed to assess the prevalence and safety of these devices as well as potential public health implications and cessation tools. For this year in review, PubMed was searched from January 2021-December 14, 2021, for articles related to e-cigarettes, vaping-related lung injury, and hookah smoking.

Cross-sectional analyses were conducted with a sample of 274 adults with COPD drawn from the second wave of the Midlife in the United States (MIDUS 2) Study. Chi-square analyses and independent -tests were used to test the differences between physically active and inactive COPD patients (active group versus inactive group) for all study variables.

Methods: African Americans (blacks) were chosen as the comparative racial group.
Article Synopsis
- * Chronic inflammation plays a crucial role in the development and worsening of COPD, resulting in various comorbidities, and current treatment options are limited.
- * Tocotrienols, a type of vitamin E, demonstrate anti-inflammatory effects that could help manage COPD by targeting inflammation pathways, making them promising candidates for new therapeutic strategies.
Introduction: Critically ill neonates are particularly susceptible to medical errors; however, few studies have evaluated NICU safety climate in the context of medical error reporting. This study aims to identify the association between perceptions of safety and culture among NICU staff with medical error reporting behaviours.
Methods: This study used a convenience sample of 79 NICU staff members (38 Nurses and 41 Respiratory Therapists).
Background: Prolonged use of both electronic cigarettes (e-cigarettes) and traditional cigarettes can increase breathing difficulties and other adverse health effects. Research is needed to provide a deeper understanding of predictors of dual use, particularly given rapid changes in the e-cigarette market and related public health communications and policy.
Methods: The sample consists of subjects in the National Longitudinal Study of Adolescent to Adult Health Wave 5 (cross-sectional) subsample ( = 3,800) from 2016 to 2018.
Background: High peak pressures delivered via bag valve mask (BVM) can be dangerous for patients.
Objective: To examine manual ventilation performance among respiratory therapists (RTs) in a simulation model.
Methods: Respiratory therapists (n=98) were instructed to ventilate a manikin for 18 breaths.
Objective: To examine whether BMI impacts the outcomes of mechanically ventilated patients.
Methods: Data was collected retrospectively among patients involved in motor vehicle accidents in intensive care at a major trauma center in Atlanta, GA. Patients were categorized into five BMI groups: underweight (BMI < 18.
Background: The purpose of this study was to assess graduate and undergraduate international respiratory therapy students' perceptions of the impact of their international educational experience on their life experience and development.
Methods: Data were collected through a validated descriptive survey. Four main dimensions of development were assessed: professional respiratory therapist (RT) role, global understanding, personal development, and intellectual development.
Background: Clinical preceptors in respiratory therapy (RT) are expected to possess effective teaching skills and qualities that signify their knowledge, expertise, and professionalism. Thus, it is important to determine which teaching characteristics are effective among RT clinical preceptors from the administrators' perspective as well as the predictors for the administrators' decisions.
Methods: A cross-sectional survey study of RT administrators was conducted in hospitals in a major southeastern metropolitan area in the United States.
Background: Aerosol face mask design and the distance at which the face mask is held from the face affect the delivery of nebulized medication to pediatric patients.
Objective: To measure the inhaled mass of nebulized albuterol with 3 types of pediatric face mask, at 3 different distances from the face, with a model of a spontaneously breathing infant.
Methods: We compared a standard pediatric face mask and 2 proprietary pediatric face masks (one shaped to resemble a dragon face, the other shaped to resemble a fish face).
Background: The literature lacks comparative data on nebulizer aerosol delivered via mask versus T-piece, to spontaneously breathing pediatric subjects.
Purpose: To compare total inhaled drug mass delivered via standard pediatric aerosol mask versus via T-piece, with increasing distance.
Methods: We used a sample of 5 nebulizers, operated under manufacturers' conditions, with a standard pediatric aerosol mask and with a T-piece capped at one end, at 0 cm, 1 cm, and 2 cm from an inhalation filter placed at the inlet of a pediatric test lung.
