Hospital palliative care is an essential part of the COVID-19 response but data are lacking. We identified symptom burden, management, response to treatment, and outcomes for a case series of 101 inpatients with confirmed COVID-19 referred to hospital palliative care. Patients (64 men, median [interquartile range {IQR}] age 82 [72e89] years, Elixhauser Comorbidity Index 6 [2e10], Australian-modified Karnofsky Performance Status 20 [10e20]) were most frequently referred for end-of-life care or symptom control. Median [IQR] days from hospital admission to referral was 4 [1e12] days. Most prevalent symptoms (n) were breathlessness (67), agitation (43), drowsiness (36), pain (23), and delirium (24). Fifty-eight patients were prescribed a subcutaneous infusion. Frequently used medicines (median [range] dose/ 24 hours) were opioids (morphine, 10 [5e30] mg; fentanyl, 100 [100e200] mcg; alfentanil, 500 [150e1000] mcg) and midazolam (10 [5e20] mg). Infusions were assessed as at least partially effective for 40/58 patients, while 13 patients died before review. Patients spent a median [IQR] of 2 [1e4] days under the palliative care team, who made 3 [2e5] contacts across patient, family, and clinicians. At March 30, 2020, 75 patients had died; 13 been discharged back to team, home, or hospice; and 13 continued to receive inpatient palliative care. Palliative care is an essential component to the COVID-19 response, and teams must rapidly adapt with new ways of working. Breathlessness and agitation are common but respond well to opioids and benzodiazepines. Availability of subcutaneous infusion pumps is essential. An international minimum data set for palliative care would accelerate finding answers to new questions as the COVID-19 pandemic develops.
This study aimed to determine whether changes in plasma heparin-releasable lipoprotein lipase (LPL) activity following a brisk walk were associated with decreases in fasting and/or postprandial triglyceride (TG) concentrations. Two groups of pre-menopausal women participated. In one group (fasting study group, n=10), TG concentrations and post-heparin plasma LPL activity were measured in the fasted state on two occasions: approximately 18 h after a 2-h treadmill walk at 50% maximal oxygen uptake (exercise trial); and after a day of no exercise (control trial). The other group (postprandial study group, n=9) undertook two oral fat tolerance tests (blood samples taken fasting and for 6 h after a high-fat meal), with plasma LPL activity measured 6 h after meal ingestion. Pre-conditions were the same as for the fasting study group (i.e. control and prior exercise). Prior exercise reduced fasting TG concentrations by 23 (7)% (fasting study group) [mean (SEM)] and by 18 (9)% (postprandial study group) (both P<0.05), and the postprandial TG response by 23 (6)% (postprandial study group) (P<0.01). Plasma LPL activity was not significantly increased by exercise in either the fasting or postprandial study groups. However, exercise-induced changes in both fasting and postprandial LPL activity were significantly correlated with the respective exercise-induced changes in fasting TG concentration and the postprandial TG response (r=-0.70 and -0.77 respectively, P<0.05 for both). These data suggest that increased LPL activity may contribute to the hypotriglyceridaemic effect of moderate exercise, although other mechanisms are also likely to be involved.
Helium has a low density and the potential of reducing the work of breathing and improving alveolar ventilation when replacing nitrogen in air. A Phase II, double-blind, randomised, prospective, controlled trial was undertaken to assess whether Heliox28 (72% He/28% O 2 ) compared with oxygen-enriched air (72% N 2 /28% O 2 ) or medical air (78.9% N 2 /21.1% O 2 ) could reduce dyspnoea and improve the exercise capability of patients with primary lung cancer and dyspnoea on exertion (Borg 43). A total of 12 patients (seven male, five female patients, age 53 -78) breathed the test gases in randomised order via a facemask and inspiratory demand valve at rest and while performing 6-min walk tests. Pulse oximetry (SaO 2 ) was recorded continuously. Respiratory rate and dyspnoea ratings (Borg and VAS) were taken before and immediately post-walk. Breathing Heliox28 at rest significantly increased SaO 2 compared to oxygen-enriched air (9672 cf. 9472, Po0.01). When compared to medical air, breathing Heliox28 but not oxygen-enriched air gave a significant improvement in the exercise capability (Po0.0001), SaO 2 (Po0.05) and dyspnoea scores (VAS, Po0.05) of lung cancer patients.
1. To examine e ectiveness/outcomes of best supportive care interventions versus cancer therapies for gastrointestinal cancer trials; 2. To determine whether trials containing best supportive care include a definition of this. Search methodsElectronic databases, grey literature sources, citation searching and reference checking, handsearches of journals and discussion with experts were used to identify potentially eligible trials from both published and unpublished sources up to July 2009. Selection criteriaRCTs comparing BSC/SC versus anticancer therapies in patients with gastrointestinal cancers. Data collection and analysisFour RCTs were found and reviewed. Because of the heterogeneity of studies, a meta-analysis was not attempted. Data were extracted from the included studies and the quality of each was assessed. Main resultsData from four studies (483 participants) were included. Due to the heterogeneity of studies (in terms of populations studied, the interventions used, the variety of outcomes and assessments used) it was not possible to make direct comparisons between the studies.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
