Objective Cardiac rehabilitation (CR) is pivotal in preventing recurring events of myocardial infarction (MI).This study aims to investigate the effect of a smartphone-based home service delivery (Care Assessment Platform) of CR (CAP-CR) on CR use and health outcomes compared with a traditional, centrebased programme (TCR) in post-MI patients. Methods In this unblinded randomised controlled trial, post-MI patients were randomised to TCR (n=60; 55.7 ±10.4 years) and CAP-CR (n=60; 55.5±9.6 years) for a 6-week CR and 6-month self-maintenance period. CAP-CR, delivered in participants' homes, included health and exercise monitoring, motivational and educational material delivery, and weekly mentoring consultations. CAP-CR uptake, adherence and completion rates were compared with TCR using intention-to-treat analyses. Changes in clinical outcomes (modifiable lifestyle factors, biomedical risk factors and health-related quality of life) across baseline, 6 weeks and 6 months were compared within, and between, groups using linear mixed model regression. Results CAP-CR had significantly higher uptake (80% vs 62%), adherence (94% vs 68%) and completion (80% vs 47%) rates than TCR ( p<0.05). Both groups showed significant improvements in 6-minute walk test from baseline to 6 weeks (TCR: 537±86-584±99 m; CAP-CR: 510±77-570±80 m), which was maintained at 6 months. CAP-CR showed slight weight reduction (89 ±20-88±21 kg) and also demonstrated significant improvements in emotional state (K10: median (IQR) 14.6 (13.4-16.0) to 12.6 (11.5-13.8)), and quality of life (EQ5D-Index: median (IQR) 0.84 (0.8-0.9) to 0.92 (0.9-1.0)) at 6 weeks.

The QoR-40 is a widely used and extensively validated measure of quality of recovery. The QoR-40 is a suitable measure of postoperative quality of recovery in a range of clinical and research situations.

Background and objective:Little is known about how comorbidities affect difficult asthma patients across different domains of asthma outcomes. We hypothesized that comorbidities in difficult asthma significantly influence asthma outcomes. Methods: We analysed 90 consecutive patients who underwent systematic assessment at our hospital's difficult asthma clinic. Eight comorbidities were assessed in all patients. They were allergic rhinitis, chronic rhinosinusitis (CRS), gastroesophageal reflux disease, obesity, obstructive sleep apnoea, anxiety or depression, dysfunctional breathing (DB) and vocal cord dysfunction (VCD). Asthma outcomes examined were exacerbation frequency (≥3/year vs <3/year), asthma control using the Asthma Control Test (ACT) and quality of life using the Asthma Quality of Life Questionnaire (AQLQ). Multivariate logistic regression was performed for dichotomous outcomes and linear regression for continuous outcomes. Analyses were adjusted for lung function and absolute blood eosinophils. Conclusion: Comorbidities independently impact a broad spectrum of outcomes in difficult asthma. Systematic evaluation of these conditions is essential in difficult asthma.

BACKGROUND Multidrug-resistant (MDR) gram-negative bacilli are important nosocomial pathogens. OBJECTIVE To determine the incidence of transmission of MDR Acinetobacter baumannii and Pseudomonas aeruginosa from patients to healthcare workers (HCWs) during routine patient care. DESIGN Prospective cohort study. SETTING Medical and surgical intensive care units. METHODS We observed HCWs who entered the rooms of patients colonized with MDR A. baumannii or colonized with both MDR A. baumannii and MDR P. aeruginosa. We examined their hands before room entry, their disposable gloves and/or gowns upon completion of patient care, and their hands after removal of gloves and/or gowns and before hand hygiene. RESULTS Sixty-five interactions occurred with patients colonized with MDR A. baumannii and 134 with patients colonized with both MDR A. baumannii and MDR P. aeruginosa. Of 199 interactions between HCWs and patients colonized with MDR A. baumannii, 77 (38.7% [95% confidence interval {CI}, 31.9%–45.5%]) resulted in HCW contamination of gloves and/or gowns, and 9 (4.5% [95% CI, 1.6%–7.4%]) resulted in contamination of HCW hands after glove removal before hand hygiene. Of 134 interactions with patients colonized with MDR P. aeruginosa, 11 (8.2% [95% CI, 3.6%–12.9%]) resulted in HCW contamination of gloves and/or gowns, and 1 resulted in HCW contamination of hands. Independent risk factors for contamination with MDR A. baumannii were manipulation of wound dressing (adjusted odds ratio [aOR], 25.9 [95% CI, 3.1–208.8]), manipulation of artificial airway (aOR, 2.1 [95% CI, 1.1–4.0]), time in room longer than 5 minutes (aOR, 4.3 [95% CI, 2.0–9.1]), being a physician or nurse practitioner (aOR, 7.4 [95% CI, 1.6–35.2]), and being a nurse (aOR, 2.3 [95% CI, 1.1–4.8]). CONCLUSIONS Gowns, gloves, and unwashed hands of HCWs were frequently contaminated with MDR A. baumannii. MDR A. baumannii appears to be more easily transmitted than MDR P. aeruginosa and perhaps more easily transmitted than previously studied methicillin-resistant Staphylococcus aureus or vancomycin-resistant Enterococcus. This ease of transmission may help explain the emergence of MDR A. baumannii.

What are the novel findings of this work? Preterm delivery occurred in a higher proportion of women with SARS-CoV-2 infection in the PAN-COVID and AAP-SONPM registries compared to contemporaneous and historical national data from uninfected women in the UK and USA. The majority of preterm deliveries occurred between 32 + 0 and 36 + 6 weeks' gestation. SARS-CoV-2 infection in pregnancy did not appear to be associated with a clinically significant effect on fetal growth, adverse neonatal outcome or the rate of stillbirth. Although maternal death was uncommon, the rate was higher than expected based on UK and USA population data, which is likely explained by underascertainment of women affected by milder or asymptomatic infection in pregnancy in the PAN-COVID study, although not in the AAP-SONPM study. What are the clinical implications of this work? Pregnant women should be counseled that SARS-CoV-2 infection increases the risk of preterm delivery but not stillbirth, early neonatal death or a small baby. Healthcare providers should recommend SARS-CoV-2 vaccination in pregnant women and women planning pregnancy, alongside enhanced social distancing.

The neuron-specific ELAV/Hu family member, HuD, interacts with and stabilizes GAP-43 mRNA in developing neurons, and leads to increased levels of GAP-43 protein. As GAP-43 protein is enriched in growth cones, it is of interest to determine if HuD and GAP-43 mRNA are associated in developing growth cones. HuD granules in growth cones are found in the central domain that is rich in microtubules and ribosomes, in the peripheral domain with its actin network, and in filopodia. This distribution of HuD granules in growth cones is dependent on actin filaments but not on microtubules. GAP-43 mRNA is localized in granules found in both the central and peripheral domains, but not in filopodia. Ribosomes were extensively colocalized with HuD and GAP-43 mRNA granules in the central domain, consistent with a role in the control of GAP-43 mRNA stability in the growth cone. Together, these results demonstrate that many of the components necessary for GAP-43 mRNA translation/stabilization are present within growth cones.
