However, data remain fraught with heterogeneity and bias from comorbid conditions. Additionally, data on the impact of COPD-specific factors, such as pre-hospital medications and pulmonologist involvement, remain sparse.Objective: We report a single-center analysis of COPD patients hospitalized with COVID-19 compared to those without COPD. Primary outcomes include ICU admission, mechanical ventilation, and in-hospital mortality.Methods: We evaluated all patients ≥ 40 years admitted with PCR-confirmed COVID-19 between February 2020 and February 2021. COPD was defined by documented ICD-10 diagnosis of COPD, confirmed smoking history, and active bronchodilator use. We compared outcomes between COPD patients and the remainder of the COVID-19 cohort. Multivariable analyses were adjusted for age, sex, smoking status, and comorbid conditions.Results: Of 1537 hospitalized COVID-19 patients, 122 (7.9%) carried a diagnosis of COPD. The COPD cohort was older (74 ± 13 vs 66 ± 15 years, P < 0.001) and more often former smokers (P < 0.001). Comorbid conditions including diabetes, cardiovascular disease, and kidney disease were more prevalent in the COPD group (P < 0.001). After adjusting for comorbid conditions, the COPD cohort had higher severity scores and trended towards fewer hospital-free days. Among patients with COPD, pre-hospital use of aspirin was associated with decreased ICU admissions (aHR 0.56, P = 0.049) and mechanical ventilation (aHR 0.25, P = 0.008), while LAMAs (long-acting muscarinic antagonists) were associated with decreased in-hospital mortality (aHR 0.34, P = 0.047). Involvement of pulmonology in pre-hospital management of COPD was not found to significantly affect outcomes.Conclusion: When corrected for comorbid illnesses, COPD was associated with more severe disease but not with increased ICU admission, mechanical ventilation, or in-hospital mortality rates. Among COPD patients, prehospital treatment with aspirin and COPD-directed therapies were associated with improved outcomes.Keywords: COVID-19, COPD, survival, critical illness, ARDS

The purpose of this study was to examine the association between oral health literacy, preventive orientation and behaviors, and chronic medical conditions-specifically, hypertension and diabetes. A cross-sectional study was conducted with dental school patients attending the dental clinics in Los Angeles, California, and Baltimore, Maryland. Their health literacy levels were measured using the short Test of Functional Health Literacy in Adults (Short-TOFHLA) and the Rapid Estimate of Adult Literacy in Medicine and Dentistry (REALM-D). The medical history and existing medical conditions-specifically, hypertension and diabetes status-were extracted from patient health history and electronic records. Ten items were asked about preventive behaviors (e.g., brushing teeth in evening, smoking, exercise, drinking soda) and 3 preventive health services (dental checkup, flu shot, medical checkup). Six locus of control items were asked (e.g., good health is a matter of good fortune, what happens to my health is God's will). Out of 793 subjects, 221 had a documented history of hypertension, 88 with diabetes. There was an association between Short-TOFHLA scores and both diabetes and hypertension, but after controlling for sociodemographic and preventive variables, the association was no longer significant. In multivariate analysis, women, people with at least some college, Asians or non-Hispanic Whites, younger people, those who spoke English as a child, those who sought health information from the Internet or health care professionals, and those who smoked reported lower utilization of preventive health services, and those who had less locus of control reported higher Short-TOFHLA scores. There were no significant differences in mean REALM-D scores between patients who had hypertension or diabetes versus not having the condition. Multivariate models showed that people with higher REALM-D scores had at least some college, were other race/ethnicity or non-Hispanic White, spoke English as a child, and sought health information via the Internet. Knowledge Transfer Statement: The results of this study show that dental school patients exhibit a range of health literacy abilities and preventive behaviors, and health literacy measures positively correlated with some preventive behaviors but not others. Dental schools receive a significant number of patients with chronic diseases, and students should be educated to use effective patient communication skills to reinforce positive health behaviors among these patients.

OBJECTIVE: The use of scoring systems contributes to the faster identification of septic patients, especially those at a high risk of a fatal outcome. The best scoring system does not exist, so the search for the optimal one is always current. The aim of this study is to estimate the prognostic value of the six scoring systems in predicting 24-hour mortality among septic patients presented at the emergency department. PATIENTS AND METHODS: An observational retrospective study was conducted in the Emergency Triage Room (ETR) of the Emergency Center (EC) at the University Clinical Center of Serbia (UCCS) in Belgrade. Consecutive septic patients, according to the Sepsis-3 definition, with or without shock, presented to the ETR and then hospitalized in Intensive Care Units were included in the study. Mortality data within 24 h and on the 28th day were extracted from the Hospital information system or the National mortality database. Scoring systems including sequential organ failure assessment (SOFA), quick sequential organ failure assessment (qSOFA), systemic inflammatory response syndrome (SIRS), National early warning score (NEWS), sepsis patient evaluation in the emergency department (SPEED), and mortality in emergency department sepsis (MEDS) were analyzed for all patients utilizing the available data. The primary outcome of this study was death within 24 hours of triage. Receiver operating characteristic (ROC) analysis was used to determine the most effective scoring system. Lactate was then added to this system to enhance its predictive accuracy. RESULTS: Nineteen out of 120 patients included in the study (15.8%) experienced death within 24 hours of triage. The twenty-eight-day mortality rate was 55%. SOFA score demonstrated the highest predictive value for 24-hour mortality but was only moderately predictive overall, with an area under the receiver operating curve (AUC) of 0.755 (95% CI 0.625-0.885). SPEED, MEDS, and NEVS exhibited modest discriminatory power [0.673 (95% CI 0.543-0.803), 0.665 (95% CI 0.536-0.794), 0.630 (95% CI 0.528- 0.724)], while SIRS and qSOFA remained insignificant in predicting 24-hour mortality. The predictive value of the SOFA score was increased by the addition of lactate (AUC 0.865, 95% CI 0.736-0.995; p=0.0081). All scores demonstrated better and satisfactory predictive power for 28-day mortality. CONCLUSIONS: SOFA, with the addition of lactate, is a complex but reliable tool for the early stratification of septic patients who are presenting at an emergency department. [ABSTRACT FROM AUTHOR]

BackgroundPredictors of worse outcomes (rebleeding, surgery and death) of peptic ulcer bleeds (PUBs) are essential indicators because of significant morbidity and mortality rates of PUBs. However those have been infrequently reported since changes in medical therapy (PPI, proton pump inhibitors) and application of newer endoscopic haemostatic technique.AimsTo determine: (i) independent risk factors for 30-day rebleeding, surgery, and death and (ii) whether ulcer size is an independent predictor of major outcomes in patients with severe PUB after successful endoscopic haemostasis and treatment with optimal medical (high dose IV PPI) vs. prior treatment (high dose IV histamine 2 antagonists - H2RAs).MethodsA large prospectively followed population of patients hospitalised with severe PUBs between 1993 and 2011 at two US tertiary care academic medical centres, stratified by stigmata of recent haemorrhage (SRH) was studied. Using multivariable logistic regression analyses, independent risk factors for each outcome (rebleeding, surgery and death) up to 30 days were analysed. Effects for medical treatment (H2RA patients 1993-2005 vs. PPIs 2006-2011) were also analysed.ResultsA total of 1264 patients were included. For ulcers ≥10 mm, the odds of 30-day rebleeding increased 6% per each 10% increase in ulcer size (OR 1.06, 95% CI 1.02-1.10, P = 0.0053). Other risk factors for 30-day rebleeding were major SRH, in-patient start of bleeding, and prior GI bleeding. Major SRH and ulcer size≥10 mm were predictors of 30-day surgery. Risk factors for 30-day death were major SRH, in-patient bleeding, and any initial platelet transfusion or fresh frozen plasma transfusion ≥2 units. Among patients with major SRH and out-patient start of bleeding, larger ulcer size was also a risk factor for death (OR 1.08 per 10% increase in ulcer size, 95% CI 1.02-1.14, P = 0.0095). Ulcer size was a significant independent variable for both time periods.ConclusionsUlcer size is a risk factor for worse outcomes after PUB and should be carefully recorded at initial endoscopy to improve patient triage and management.
