Abstract

Educational Aims To illustrate the common mechanisms limiting exercise tolerance in patients with chronic lung and heart disease To highlight the impact of lung and heart disease on daily physical activity levels To outline the effects of cardiopulmonary rehabilitation on functional capacity in patients with chronic lung and heart disease To discuss an innovative tele-rehabilitation intervention using information and communications technologies to improve functional capacity in patients with chronic lung and heart disease Summary Shortness of breath associated with cardiorespiratory abnormalities and peripheral muscle discomfort are the major factors that limit exercise capacity in patients with chronic obstructive pulmonary disease (COPD) and those with congestive heart failure (CHF). Both of these symptoms negatively impact on patients’ daily physical activity levels. In turn, poor daily physical activity is commonly associated with increased rates of morbidity and mortality. Cardiopulmonary rehabilitation programmes partially reverse muscle weakness and dysfunction and increase functional capacity in both COPD and CHF. However, benefits gained from participation in cardiopulmonary rehabilitation programmes are regressing soon after the completion of these programmes. Moreover, several barriers limit access and uptake of cardiopulmonary rehabilitation programmes by eligible patients. A potential solution to the underutilisation of cardiopulmonary rehabilitation is the implementation of tele-rehabilitation interventions at home using information and communications technologies. Thus, tele-rehabilitation may be useful to encourage and educate patients with COPD or CHF on how best to maintain and/or further enhance daily physical activity levels.

  • Using radiolabeled SSTR antagonists, especially LM3 and JR11, may provide more successful imaging and PRRT strategies for neuroendocrine tumors, even those with relatively low SSTR expression, compared to agonists.

    “Taking the proposed mechanism, preclinical and clinical studies into consideration, it is obvious that using radiolabeled SSTR antagonists, especially LM3 and JR11, may provide more successful imaging and PRRT strategies for neuroendocrine tumors, even those with relatively low SSTR expression (130, 137, 141) compared to agonists.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
