Intimately dimorphic muscarinic acetylcholine receptor modulation associated with contextual worry learning in the dentate gyrus.
Frailty is highly prevalent among older adults with cardiovascular disease (CVD) and is associated with greater than 2-fold risk for morbidity and mortality, independent of age and comorbidities. Many candidates are not referred to cardiac rehabilitation (CR) under the assumption that they are too frail to benefit. We hypothesized that CR is associated with similar benefits for frail adults as for intermediate-frail and nonfrail adults.

Retrospective analysis of CVD patients who completed a phase II CR program. Patients classified as frail by meeting ≥2 frailty criteria and intermediate-frail by meeting 1 criterion, including 6-min walk distance (6MWD) <300 m, gait speed ≤0.65 m/sec or 0.76 m/sec normalized to height and sex, tandem stand <10 sec, Timed Up & Go (TUG) <15 sec, and weak hand grip strength per Fried criteria. Changes within and between groups were compared before and after completion of CR.

We evaluated 243 patients; 75 were classified as frail, 70 as intermediate-frail, and 9gible patients to CR, including frail patients. Those who are most physically impaired may derive gains that have proportionally greater ramifications.
The coronavirus disease-2019 (COVID-19) pandemic has been spreading rapidly worldwide since late January 2020. The strict lockdown strategy prompted by the Italian government, to hamper severe acute respiratory syndrome coronavirus 2 (SARS-CoV2) spreading, has reduced the possibility of performing either outdoor or gym physical activity (PA). This study investigated and quantified the reduction of PA in patients with automatic implantable cardioverter-defibrillators (ICDs) for primary prevention of sudden death.

Daily PA of 24 patients was estimated by processing recorded data from ICD-embedded accelerometric sensors used by the rate-responsive pacing systems.

During the forced 40-d in-home confinement, a mean 25% reduction of PA was observed as compared with the 40-d confinement-free period (1.2 ± 0.3 vs 1.6 ± 0.5 hr/d, respectively, P = .0001).

This objective quantification of the impact of the COVID-19 pandemic on PA determined by an ICD device showed an abrupt and statistically significant reduction of PA in primary prevention ICD patients, during the in-home confinement quarantine. To counteract the deleterious effects of physical inactivity during the COVID-19 outbreak, patients should be encouraged to perform indoor exercise-based personalized rehabilitative programs.

Chronic obstructive pulmonary disease (COPD) and abnormalities of left ventricular (LV) geometry often coexist. This study aimed to verify whether LV geometry is associated with airflow obstruction, functional capacity, and grip strength in COPD patients.

Thirty-seven COPD patients (GOLD II, III, and IV) were allocated to three groups according to LV geometry as assessed by transthoracic echocardiography normal (n = 13), concentric LV remodeling (n = 8), and concentric LV hypertrophy (LVH) (n = 16). buy CBR-470-1 Lung function was assessed using spirometry. The Duke Activity Status Index (DASI) was used to estimate functional capacity, and grip strength measurement was performed using a hydraulic hand dynamometer.

The concentric LVH group presented lower DASI scores (P = .045) and grip strength (P = .006) when compared with the normal group. Correlations analysis showed the following relative wall thickness negatively correlated with forced expiratory volume in the first second (r = -0.380; P = .025) and DASI score (r = -0.387, P = .018); LV mass index negatively correlated with grip strength (r = -0.363, P = .038).

In COPD patients, LV geometry is associated with airflow limitation, functional capacity, and grip strength. Specifically, concentric LV remodeling is associated with increased airflow limitation and decreased functional capacity whereas increased LV mass is associated with decreased grip strength.

To determine clinician accuracy in the identification and prediction of multiple organ dysfunction syndrome.

Prospective cohort study.

University of Michigan's C.S. Mott Children's Hospital PICU.

Patients admitted to the PICU with an anticipated PICU length of stay greater than 48 hours.

None.

For each patient, the clinical team (attending, fellow, resident/nurse practitioner) was surveyed regarding existing and anticipated organ dysfunction. The primary outcomes were clinicians' accuracy at identifying multiple organ dysfunction syndrome and predicting new or progressive multiple organ dysfunction syndrome, compared to the objective assessment of multiple organ dysfunction syndrome using Proulx criteria. We also measured sensitivity, specificity, negative and positive predictive values, and negative and positive likelihood ratios of clinician assessments. We tested for differences in accuracy by clinician type using chi-square tests. Clinicians rated their confidence in prediction on a 5-point Lioped new or progressive multiple organ dysfunction syndrome, so accuracy was largely due to true negative predictions. The positive predictive value for new or progressive multiple organ dysfunction syndrome prediction was just 22%. Accuracy did not differ by clinician type, but was correlated with self-rated confidence and was higher for negative predictions.
The outcomes reported in trials in coronavirus disease 2019 are extremely heterogeneous and of uncertain patient relevance, limiting their applicability for clinical decision-making. The aim of this workshop was to establish a core outcomes set for trials in people with suspected or confirmed coronavirus disease 2019.

Four international online multistakeholder consensus workshops were convened to discuss proposed core outcomes for trials in people with suspected or confirmed coronavirus disease 2019, informed by a survey involving 9,289 respondents from 111 countries. The transcripts were analyzed thematically. The workshop recommendations were used to finalize the core outcomes set.

International.

Adults 18 years old and over with confirmed or suspected coronavirus disease 2019, their family members, members of the general public and health professionals (including clinicians, policy makers, regulators, funders, researchers).

None.

None.

Six themes were identified. "Responding to the critical and acute health crisis" reflected the immediate focus on saving lives and preventing life-threatening complications that underpinned the high prioritization of mortality, respiratory failure, and multiple organ failure.
