Introduction Exercise improves functional outcome and symptoms for certain cancer populations, but the feasibility, efficacy, and safety of structured exercise in patients with lung cancer is unknown. In this study, we examined the feasibility of a hospital-based exercise program for patients with advanced non-small cell lung cancer. Methods This study included patients with newly diagnosed advanced stage non-small cell lung cancer and Eastern Cooperative Oncology Group performance status 0–1. A physical therapist facilitated twice-weekly sessions of aerobic exercise and weight training over an 8-week period. The primary end point was feasibility of the intervention, defined as adherence to the exercise program. Secondary endpoints included functional capacity, measured by the 6-minute walk test and muscle strength, as well as quality of life, lung cancer symptoms and fatigue, measured by the Functional Assessment of Cancer Therapy-lung and Functional Assessment of Cancer Therapy-fatigue scales. Results Between October 2004 and August 2007, 25 patients enrolled in the study. All participants received anticancer therapy during the study period. Twenty patients (80%) underwent the baseline physical therapy evaluation. Eleven patients (44%) completed all 16 sessions. An additional 6 patients attended at least 6 sessions (range, 6–15), and 2 patients only attended one session. Study completers experienced a significant reduction in lung cancer symptoms and no deterioration in their 6-minute walk test or muscle strength. Conclusions Although the majority of participants attempted the exercise program, less than half were able to complete the intervention. Those who completed the program experienced an improvement in their lung cancer symptoms. Community-based or briefer exercise interventions may be more feasible in this population.

Corticosteroids for Bell's palsy (idiopathic facial paralysis).

The matrix metalloproteinases (MMPs) have been implicated in a number of diseases involving inflammation or cellular invasion.' GM 6001 (FIG. 1) is an inhibitor of most of these enzymes with Ki's in the low nanomolar range. Though potent in vitro, this molecule is short-lived in circulation with a half-life of a few minutes.We show here that topical GM 6001 prevents the infiltration of inflammatory cells into the alkali-burned rabbit cornea and into phorbol ester-stimulated mouse skin. It thus prevents ulceration in the former and psoriasis-like inflammation and proliferation in the latter. When given systemically it blocks the infiltration of cells into the peritoneal cavity of mice stimulated with thioglycollate. Topical administration of this drug inhibits angiogenesis in the chick chorioallantoic membrane. When given intravenously, it inhibits angiogenesis in rat corneas implanted with a pellet containing tumor extract, a process requiring penetration of vascular basement membrane by endothelial cells. Finally, systemic GM 6001 increases survival of mice in a B16-Fl0 melanoma metastasis model, presumably by inhibiting cellular invasion or tumor growth.In addition to the potential for preventing direct destruction of connective tissue

Background COVID-19 is a multisystem disease and patients who survive might have in-hospital complications. These complications are likely to have important short-term and long-term consequences for patients, health-care utilisation, health-care system preparedness, and society amidst the ongoing COVID-19 pandemic. Our aim was to characterise the extent and effect of COVID-19 complications, particularly in those who survive, using the International Severe Acute Respiratory and Emerging Infections Consortium WHO Clinical Characterisation Protocol UK.Methods We did a prospective, multicentre cohort study in 302 UK health-care facilities. Adult patients aged 19 years or older, with confirmed or highly suspected SARS-CoV-2 infection leading to COVID-19 were included in the study. The primary outcome of this study was the incidence of in-hospital complications, defined as organ-specific diagnoses occurring alone or in addition to any hallmarks of COVID-19 illness. We used multilevel logistic regression and survival models to explore associations between these outcomes and in-hospital complications, age, and pre-existing comorbidities. FindingsBetween Jan 17 and Aug 4, 2020, 80 388 patients were included in the study. Of the patients admitted to hospital for management of COVID-19, 49•7% (36 367 of 73 197) had at least one complication. The mean age of our cohort was 71•1 years (SD 18•7), with 56•0% (41 025 of 73 197) being male and 81•0% (59 289 of 73 197) having at least one comorbidity. Males and those aged older than 60 years were most likely to have a complication (aged ≥60 years:
