Context: The use of sedation allows medical procedures to be performed outside the operating room while ensuring patient comfort and a controlled environment to increase the yield of the procedure. There is concern about a higher risk of adverse events with use of sedation in patients with obstructive sleep apnea.', 'We aimed to determine if the presence of obstructive sleep apnea increased the risk of hospitalization and/or health care use after patients received moderate conscious sedation for an elective, ambulatory colonoscopy.', 'We conducted a retrospective case-control database and chart review study. We compared hospital admissions, intensive care unit (ICU) admissions, and emergency room visits at 24 hours, 7 days, and 30 days in patients with obstructive sleep apnea (n=3,860) and without obstructive sleep apnea (n=2,374) who had undergone an elective, ambulatory colonoscopy with sedation.', 'We found no significant differences in hospital admissions, ICU admissions, or emergency room visits between the two groups at any time point within the 30 days following the procedures. In a sensitivity analysis in which we compared 827 individuals with polysomnographically confirmed sleep apnea with control subjects, there was still no difference in hospital admissions, ICU admissions, or emergency room visits in the 30 days after receiving sedation for the procedure. Outcomes were not different in individuals with various severities of obstructive sleep apnea.
Answer: The presence of obstructive sleep apnea was not associated with increased early hospital admissions, ICU admissions, or emergency room visits after colonoscopy with sedation.
answer:
Is obstructive Sleep Apnea Associated with Higher Health Care Use after Colonoscopy under Conscious Sedation?

Context: Adrenocortical carcinoma (ACC) is a rare and aggressive malignancy with poor prognosis, as a majority of patients present with advanced disease. Current adjuvant strategies for metastatic patients include mitotane or other cytotoxic agents and carry a significant morbidity as well as a low (<10 %) 5-year survival. Withanolides, including withaferin A, are novel chemotherapeutic agents with potent targeted effects in medullary thyroid cancer and a number of solid malignancies with low toxicity in vivo. We hypothesize that novel naturally derived withanolides will have potent targeted anti-cancer activity against ACCs.', 'In vitro cell viability of ACC cell lines (Y1 and SW13) was measured using MTS cell proliferation assay. Cell cycle and apoptotic analysis studied using annexin V/propidium iodide staining on flow cytometry (FC) and targeted molecular mechanisms of withanolide cytotoxicity were assessed using standard Western blot analysis.', 'All the withanolides potently reduced ACC cell viability on MTS assay with 7- to 185-fold higher selectivity than normal fibroblasts. Cell cycle analysis demonstrated a shift in cell cycle arrest from G1/G0 to G2/M with induction of apoptosis at nanomolar concentrations of withanolides. Unlike current ACC therapeutics, withanolides modulated expression of several key oncogenic pathway proteins in ACCs by Western blot, including Jagged 1, MAPK, and Akt/mTOR pathway proteins in a dose-dependent manner after 24 h drug treatment of SW13 cells.
Answer: These results demonstrate the first evidence of the anticancer efficacy of withanolides in ACC cells and provide support for future translational evaluation of these compounds as novel therapeutic agents for ACC patients.
answer:
Are withanolides potent novel targeted therapeutic agents against adrenocortical carcinomas?

question:
Context: Increased small airway resistance and decreased lung elasticity contribute to the airflow limitation in chronic obstructive pulmonary disease (COPD). The lesion that corresponds to loss of lung elasticity is emphysema; the small airway obstruction is due to inflammatory narrowing and obliteration. Despite their convergence in altered physiology, different mechanisms contribute to these processes. The relationships between gene expression and these specific phenotypes may be more revealing than comparison with lung function.', 'We measured the ratio of alveolar surface area to lung volume (SA/V) in lung tissue from 43 smokers. Two samples from 21 subjects, in which SA/V differed by >49 cm2/mL were profiled to select genes whose expression correlated with SA/V. Significant genes were tested for replication in the 22 remaining subjects.', 'The level of expression of 181 transcripts was related to SA/V ( p < 0.05). When these genes were tested in the 22 remaining subjects as a replication, thirty of the 181 genes remained significantly associated with SA/V (P < 0.05) and the direction of association was the same in 164/181. Pathway and network analysis revealed enrichment of genes involved in protein ubiquitination, and western blotting showed altered expression of genes involved in protein ubiquitination in obstructed individuals.
Answer: This study implicates modified protein ubiquitination and degradation as a potentially important pathway in the pathogenesis of emphysema.
answer:
Are genes related to emphysema enriched for ubiquitination pathways?
