Abstract
Background As the number of adults with congenital heart disease increases because of therapeutic advances, cardiac rehabilitation (CR) is increasingly being used in this population after cardiac procedures or for reduced exercise tolerance. We aim to describe the adherence and exercise capacity improvements of patients with adult congenital heart disease (ACHD) in CR. Methods and Results This retrospective study included patients with ACHD in CR at New York University Langone Rusk Rehabilitation from 2013 to 2020. We collected data on patient characteristics, number of sessions attended, and functional testing results. Pre‐CR and post‐CR metabolic equivalent task, exercise time, and maximal oxygen uptake were assessed. In total, 89 patients with ACHD (mean age, 39.0 years; 54.0% women) participated in CR. Referral indications were reduced exercise tolerance for 42.7% and post–cardiac procedure (transcatheter or surgical) for the remainder. Mean number of sessions attended was 24.2, and 42 participants (47.2%) completed all 36 CR sessions. Among participants who completed the program as well as pre‐CR and post‐CR functional testing, metabolic equivalent task increased by 1.3 (95% CI, 0.7–1.9; baseline mean, 8.1), exercise time increased by 66.4 seconds (95% CI, 21.4–111.4 seconds; baseline mean, 536.1 seconds), and maximal oxygen uptake increased by 2.5 mL/kg per minute (95% CI, 0.7–4.2 mL/kg per minute; baseline mean, 20.2 mL/kg per minute). Conclusions On average, patients with ACHD who completed CR experienced improvements in exercise capacity. Efforts to increase adherence would allow more patients with ACHD to benefit.

Abstract
Background Participation in ambulatory cardiac rehabilitation remains low, especially among older adults. Although mobile health cardiac rehabilitation (mHealth-CR) provides a novel opportunity to deliver care, age-specific impairments may limit older adults’ uptake, and efficacy data are currently lacking. Objective This study aims to describe the design of the rehabilitation using mobile health for older adults with ischemic heart disease in the home setting (RESILIENT) trial. Methods RESILIENT is a multicenter randomized clinical trial that is enrolling patients aged ≥65 years with ischemic heart disease in a 3:1 ratio to either an intervention (mHealth-CR) or control (usual care) arm, with a target sample size of 400 participants. mHealth-CR consists of a commercially available mobile health software platform coupled with weekly exercise therapist sessions to review progress and set new activity goals. The primary outcome is a change in functional mobility (6-minute walk distance), which is measured at baseline and 3 months. Secondary outcomes are health status, goal attainment, hospital readmission, and mortality. Among intervention participants, engagement with the mHealth-CR platform will be analyzed to understand the characteristics that determine different patterns of use (eg, persistent high engagement and declining engagement). Results As of December 2021, the RESILIENT trial had enrolled 116 participants. Enrollment is projected to continue until October 2023. The trial results are expected to be reported in 2024. Conclusions The RESILIENT trial will generate important evidence about the efficacy of mHealth-CR among older adults in multiple domains and characteristics that determine the sustained use of mHealth-CR. These findings will help design future precision medicine approaches to mobile health implementation in older adults. This knowledge is especially important in light of the COVID-19 pandemic that has shifted much of health care to a remote, internet-based setting.

Abstract
Background and Objective Non-tuberculous mycobacterial lung disease (NTM-LD) manifests with bronchiectasis, inflammatory bronchiolitis, nodules, and/or cavitation. Bronchiectasis is characterized by permanently dilated airways wherein mucus accumulates, creating a vicious cycle of chronic injurious inflammation and recurrent infections. While antibiotics are an important part of the treatment of NTM-LD, airway clearance techniques to mitigate this pathogenic mechanism of bronchiectasis as well as other ancillary measures are also important components of NTM-LD treatment. The objective of this contemporaneous Narrative Review is to emphasize the importance of such ancillary measures. Methods We searched PubMed for the key words of “airway clearance”, “pulmonary rehabilitation”, “nutrition”, “swallowing dysfunction”, “gastroesophageal reflux”, “vestibular dysfunction”, or “cochlear dysfunction” with that of “non-tuberculous mycobacterial lung disease”, “bronchiectasis”, or “respiratory disease”. The bibliographies of identified articles were further searched for relevant articles not previously identified. Each relevant article was reviewed by one or more of the authors and a narrative review was composed. Key Content and Findings Herein, we discuss five ancillary treatment measures that are pertinent to patients with bronchiectasis and NTM-LD: (I) airway clearance; (II) physical and pulmonary rehabilitation; (III) nutrition; (IV) diagnosis and mitigation of swallowing dysfunction and of gastroesophageal reflux disease (GERD); and (V) minimization of vestibular and cochlear dysfunction associated with some anti-NTM drugs. Conclusions While antibiotics is often the central focus of treatment of NTM-LD, given its propensity for recurrent and recalcitrant infection, other ancillary measures to break the vicious cycle of injurious inflammation and infection should also be emphasized to optimize treatment success.

Abstract
Dyspnoea self-management is often suboptimal for patients with COPD. Many patients with COPD experience chronic dyspnoea as distressing and disabling, especially during physical activities. Breathing therapy is a behavioural intervention that targets reducing the distress and impact of dyspnoea on exertion in daily living. Using a qualitative design, we conducted interviews with 14 patients after they participated in a novel mind–body breathing therapy intervention adjunct, capnography-assisted respiratory therapy (CART), combined with outpatient pulmonary rehabilitation. Comprehensive CART consisted of patient-centred biofeedback, tailored breathing exercises, a home exercise programme and motivational interviewing counselling. We assessed participants’ perceptions and reported experiences to gauge the acceptability of CART and refine CART based on feedback. Constant comparative analysis was used to identify commonalities and themes. We identified three main themes relating to the acceptability and reported benefits of CART: (1) self-regulating breathing; (2) impact on health; and (3) patient satisfaction. Our findings were used to refine and optimise CART (i.e. its intensity, timing and format) for COPD. By addressing dysfunctional breathing behaviours and dysregulated interoception, CART offers a promising new paradigm for relieving dyspnoea and related anxiety in patients with COPD. Capnography-assisted respiratory therapy (CART) is a new adjunctive mind–body therapy. Patients with COPD find CART to be acceptable and to complement pulmonary rehabilitation.https://bit.ly/3iP4glN

Abstract
Abstract
Background
Korian® group is specialized in care and support for fragile people. Its data warehouse manages 304 French nursing homes (NH). The transmissions' table (TT), daily-fed by caregivers, contains key data about residents' care and health. Following GDPR rules, we could still build residents' life trajectories and detail all the residents' health events using indexes. In the past, we designed syndromes such as falls, flu, and last year, COVID with the standard query language. Now we want to combine ‘hard' data such as sociodemographic profiles and COVID vaccines with ‘soft' textual data such as COVID and emergency calls syndromes to get a better residents vaccine monitoring.
Methods
First, we selected all residents with at least one transmission, from December 21, to January 11, just before the COVID vaccination start, from 34 NH chosen for their variety of size and geographic location. We followed them for eleven weeks starting January 4, 2021. We selected the residents' age, sex, autonomy level, comorbidities and risks and then, vaccinations (0, 1 or 2), syndromes, hospitalizations and deaths date events. We searched for sample data inconsistencies by filtering COVID textual information in the TT and comparing it with the vaccination table. We described the sample according to the NH size, and then according to the number of vaccinations. Finally, we assessed COVID syndromes, falls, hospitalizations, emergency calls and deaths according to vaccinations followed by Poisson and logistic regressions.
Results
We built a 2,051 residents cohort with 1,401 vaccinated at least once and 650 not yet vaccinated. Data corrections then added 60 vaccinations. Residents in big structures were more masculine (72,9% vs 75,1%), more vaccinated (77,2% vs 67,2%), younger (86,7 vs 87,5), more autonomous (2,6, vs 2,4). Vaccination rates were also greater among those with comorbidities and risks.
Conclusions
By focusing on the TT resident's health events, we improved health modelization
Key messages
By using all the COVID information available in the database, we were able to show both, the beneficial effect of vaccination and the nefarious effect of COVID in a same model with machine learning. Aggregating hard categorical and numerical data with soft textual information about the resident’s health events, dates included, gives a precise and complete resident’s profile and health trajectory.

Abstract
Type-I x-ray bursts can reveal the properties of an accreting neutron star system when compared with astrophysics model calculations. However, model results are sensitive to a handful of uncertain nuclear reaction rates, such as ^{22}Mg(α,p). We report the first direct measurement of ^{22}Mg(α,p), performed with the Active Target Time Projection Chamber. The corresponding astrophysical reaction rate is orders of magnitude larger than determined from a previous indirect measurement in a broad temperature range. Our new measurement suggests a less-compact neutron star in the source GS1826-24.

Abstract
PURPOSE Despite known benefits of cardiac rehabilitation (CR), early termination (failure to complete >1 mo of CR) attenuates these benefits. We analyzed whether early termination varied by referral indication in the context of recent growth in patients referred for heart failure with reduced ejection fraction (HFrEF). METHODS We reviewed records from 1111 consecutive patients enrolled in the NYU Langone Health Rusk CR program (2013-2017). Sessions attended, demographics, and comorbidities were abstracted, as well as primary referral indication: HFrEF or ischemic heart disease (IHD; including post-coronary revascularization, post-acute myocardial infarction, or chronic stable angina). We compared rates of early termination between HFrEF and IHD, and used multivariable logistic regression to determine whether differences persisted after adjusting for relevant characteristics (age, race, ethnicity, body mass index, smoking, hypertension, chronic obstructive pulmonary disease, and depression). RESULTS Mean patient age was 64 yr, 31% were female, and 28% were nonwhite. Most referrals (85%) were for IHD; 15% were for HFrEF. Early termination occurred in 206 patients (18%) and was more common in HFrEF (26%) than in IHD (17%) (P < .01). After multivariable adjustment, patients with HFrEF remained at higher risk of early termination than patients with IHD (unadjusted OR = 1.73, 95% CI, 1.17-2.54; adjusted OR = 1.53, 95% CI, 1.01-2.31). CONCLUSIONS Nearly 1 in 5 patients in our program terminated CR within 1 mo, with HFrEF patients at higher risk than IHD patients. While broad efforts at preventing early termination are warranted, particular attention may be required in patients with HFrEF.

Abstract
BACKGROUND Obesity is a risk factor for stress-related mental disorders such as post-traumatic stress disorder. The underlying mechanism through which obesity affects mental health remains poorly understood but dysregulation of the ghrelin system may be involved. Stress increases plasma ghrelin levels, which stimulates food intake as a potential stress-coping mechanism. However, diet-induced obesity induces ghrelin resistance which in turn may have deleterious effects on stress-coping. In our study, we explored whether disruption of ghrelin receptor function though high-fat diet or genetic ablation affects fear processing, anxiety-like behavior and saccharin preference in mice. METHODS Adult male C57BL6/J mice were placed on a standard diet or high-fat diet for a total period of 8 weeks. We first established that high-fat diet exposure for 4 weeks elicits ghrelin resistance, evidenced by a blunted hyperphagic response following administration of a ghrelin receptor agonist. We then carried out an experiment in which we subjected mice to auditory fear conditioning after 4 weeks of diet exposure and evaluated effects on fear extinction, anxiety-like behavior and saccharin preference. To explore whether fear conditioning as such may influence the effect of diet exposure, we also subjected mice to auditory fear conditioning prior to diet onset and 4 weeks later we investigated auditory fear extinction, anxiety-like behavior and saccharin preference. In a final experiment, we further assessed lack of ghrelin receptor function by investigating auditory fear processing, anxiety-like behavior and saccharin preference in ghrelin receptor knockout mice and their wild-type littermates. RESULTS High-fat diet exposure had no significant effect on auditory fear conditioning and its subsequent extinction or on anxiety-like behavior but significantly lowered saccharin preference. Similarly, ghrelin receptor knockout mice did not differ significantly from their wild-type littermates for auditory fear processing or anxiety-like behavior but showed significantly lower saccharin preference compared to wild-type littermates. CONCLUSION Taken together, our data suggest that disruption of ghrelin receptor function per se does not affect fear or anxiety-like behavior but may decrease saccharin preference in mice.

Abstract
The prognosis for locally advanced esophageal cancer is poor despite the use of trimodality therapy. In this phase II study, we report the feasibility, tolerability and efficacy of adjuvant sunitinib. Included were patients with stage IIa, IIB or III cancer of the thoracic esophagus or gastroesophageal junction. Neoadjuvant therapy involved Irinotecan (65 mg/m2 ) + Cisplatin (30 mg/m2 ) on weeks 1 and 2, 4 and 5, 7 and 8 with concurrent radiation (50Gy/25 fractions) on weeks 4-8. Sunitinib was commenced 4-13 weeks after surgery and continued for one year. Sixty-one patients were included in the final analysis, 36 patients commenced adjuvant sunitinib. Fourteen patients discontinued sunitinib due to disease recurrence (39%) within the 12-month period, 12 (33%) discontinued due to toxicity, and 3 (8%) requested cessation of therapy. In the overall population, median survival was 26 months with a 2 and 3-year survival rate of 52% and 35%, respectively. The median survival for the 36 patients treated with sunitinib was 35 months and 2-year survival probability of 68%. In a historical control, a prior phase II study with the same trimodality therapy (n = 43), median survival was 36 months, with a 2-year survival of 67%. Initiation of adjuvant sunitinib is feasible, but poorly tolerated, with no signal of additional benefit over trimodality therapy for locally advanced esophageal cancer.

Abstract
The adsorption of polymeric sulphonated naphthalene formaldehyde (SNF) and sulphonated melamine formaldehyde (SMF) on to titanium dioxide and calcium carbonate has been measured in aqueous media. The magnitude of these adsorptions is strongly dependent on electrostatic interaction irrespective of the pH value. This result has been established by studying the adsorption of the polyelectrolytes from solutions of different composition. The calcium ion plays a prominent role in the process of adsorption, especially at high pH where electrical interactions do not favour the reaction. The polymeric nature of the fluidizing agents is demonstrated by an increase in adsorption with molecular weight and by adsorption/desorption experiments where the reaction has been shown to be irreversible. The amount adsorbed at maximum coverage does not depend on the nature of the mineral, but mainly on electrical interactions between the monomer units.

Abstract
The growing demand for suitable lungs for transplantation drives the quest for alternative strategies to expand the donor pool. The aim of this study is to evaluate the outcomes of lung transplantation (LTx) with donation after circulatory determination of death (DCDD) and the impact of selective ex vivo lung perfusion (EVLP). From 2007 to 2013, 673 LTx were performed, with 62 (9.2%) of them using DCDDs (seven bridged cases). Cases bridged with mechanical ventilation/extracorporeal life support were excluded. From 55 DCDDs, 28 (51%) underwent EVLP. Outcomes for LTx using DCDDs and donation after neurological determination of death (DNDD) donors were similar, with 1 and 5-year survivals of 85% and 54% versus 86% and 62%, respectively (p = 0.43). Although comparison of survival curves between DCDD + EVLP versus DCDD-no EVLP showed no significant difference, DCDD + EVLP cases presented shorter hospital stay (median 18 vs. 23 days, p = 0.047) and a trend toward shorter length of mechanical ventilation (2 vs. 3 days, p = 0.059). DCDDs represent a valuable source of lungs for transplantation, providing similar results to DNDDs. EVLP seems an important technique in the armamentarium to safely increase lung utilization from DCDDs; however, further studies are necessary to better define the role of EVLP in this context.

Abstract
Evaluate the use of multiplex real-time PCR for diagnosing respiratory infections. 857/966 samples from 914 children were positive for one or multiple viruses. Respiratory syncytial virus and rhinovirus were the most prevalent. Co-infections were associated with severe respiratory symptoms. The spread of respiratory viruses returned to the one it was before the flu outbreak.
Background The use of a multiplex molecular technique to identify the etiological pathogen of respiratory viral infections might be a support as clinical signs are not characteristic. Objectives The aim of the study was to evaluate a multiplex molecular real-time assay for the routine diagnosis of respiratory viruses, to analyze the symptoms associated with the pathogens detected and to determine the spread of virus during the period. Study design Respiratory samples were collected from children presenting with respiratory symptoms and attending the emergency unit during the 2010–2011 winter seasons. Samples were tested with the multiplex RespiFinder® 15 assay (PathoFinder™) which potentially detects 15 viruses. Results 857 (88.7%) of the 966 samples collected from 914 children were positive for one (683 samples) or multiple viruses (174 samples). The most prevalent were the respiratory syncytial virus (39.5%) and the rhinovirus (24.4%). Influenza viruses were detected in 139 (14.4%) samples. Adenovirus was detected in 93 (9.6%) samples, coronaviruses in 88 (9.1%), metapneumovirus in 51 (5.3%) and parainfluenzae in 47 (4.9%). Rhinovirus (40%) was the most prevalent pathogen in upper respiratory tract infections while respiratory syncytial virus (49.9%) was the most prevalent in lower respiratory tract infections. Co-infections were associated with severe respiratory symptoms. Conclusion The multiplex assay detected clinically important viruses in a single genomic test and thus will be useful for detecting several viruses causing respiratory tract disorders.

Abstract
Treatment of injured donor lungs ex vivo to accelerate organ recovery and ameliorate reperfusion injury could have a major impact in lung transplantation. We have recently demonstrated a feasible technique for prolonged (12 h) normothermic ex vivo lung perfusion (EVLP). This study was performed to examine the impact of prolonged EVLP on ischemic injury. Pig donor lungs were cold preserved in Perfadex for 12 h and subsequently divided into two groups: cold static preservation (CSP) or EVLP at 37 degrees C with Steen solution for a further 12 h (total 24 h preservation). Lungs were then transplanted and reperfused for 4 h. EVLP preservation resulted in significantly better lung oxygenation (PaO(2) 531 +/- 43 vs. 244 +/- 49 mmHg, p < 0.01) and lower edema formation rates after transplantation. Alveolar epithelial cell tight junction integrity, evaluated by zona occludens-1 protein staining, was disrupted in the cell membranes after prolonged CSP but not after EVLP. The maintenance of integrity of barrier function during EVLP translates into significant attenuation of reperfusion injury and improved graft performance after transplantation. Integrity of functional metabolic pathways during normothermic perfusion was confirmed by effective gene transfer and GFP protein synthesis by lung alveolar cells. In conclusion, EVLP prevents ongoing injury associated with prolonged ischemia and accelerates lung recovery.

Abstract
We describe a novel technique of pumpless extracorporeal life support in four patients with cardiogenic shock due to end-stage pulmonary hypertension (PH) including patients with veno-occlusive disease (PVOD) using a pumpless lung assist device (LAD). The device was connected via the pulmonary arterial main trunk and the left atrium, thereby creating a septostomy-like shunt with the unique addition of gas exchange abilities in parallel to the lung. Using this approach, all four patients were successfully bridged to bilateral lung transplantation and combined heart-lung transplantation, respectively. Although all patients presented in cardiogenic shock, hemodynamic unloading of the right ventricle using the low-resistance LAD stabilized the hemodynamic situation immediately so that no pump support was subsequently required.
