The COVID-19 pandemic influenced emotional experiences globally. We examined daily positive and negative affect between May/June 2020 and February 2021 (N = 151,049; 3,509,982 observations) using a convenience sample from a national mobile application-based survey that asked for daily affect reports. Four questions were examined: (1) How did people in the United States feel from May/June 2020 to February 2021?; (2) What demographic variables are related to positive and negative affect?; (3) What is the relationship between experienced stressors and daily affect?; and (4) What is the relationship between daily affect and preventive behavior? Positive affect increased, and negative decreased over time. Demographic differences mirrored those from before the pandemic (e.g., younger participants reported more negative and less positive affect). Stressors such as feeling unwell, experiencing COVID-19 symptoms, exposure to COVID-19, and lack of sleep were associated with less positive and more negative affect. Exercising protective behaviors predicted future affect, and affect also predicted future protective behaviors (e.g., less protective behavior when happy but more when grateful and thoughtful). The implications for public health communication were discussed. [ABSTRACT FROM AUTHOR]

Background: Surgical management of intrahepatic cholangiocarcinoma routinely includes resection of the hepatic parenchyma, yet the role of lymphadenectomy (LND) is more controversial. The objective of the current study was to define overall utilization, as well as temporal trends, in the utilization of LND among patients undergoing curative-intent hepatectomy for ICC using a nationwide database.Materials and Methods: One thousand four hundred ninety-six patients who underwent curative-intent resection for ICC were identified using the SEER database from 2000 to 2013. The utilization of LND was assessed over time and by geographic region. LND utilization and the incidence of lymph node metastasis (LNM) were evaluated relative to AJCC T categories.Results: At the time of surgery, slightly over one-half of patients (n = 784, 52.4%) had at least one LN evaluated. Specifically, 613 (41.0%) patients had 1-5 LNs evaluated, whereas 171 (11.4%) patients had ≥ 6 LNs evaluated. The proportion of patients who had at least one LN evaluated at the time of surgery did not change with time (2000-2004: 50.5% vs. 2005-2009: 52.0% vs. 2010-2013: 53.7%) (p = 0.636). In contrast, the proportion of patients who had ≥ 6 LNs examined did increase (2000-2004: 6.9% vs. 2005-2009: 10.6% vs. 2009-2013: 14.3%) (p = 0.003). The risk of LNM was higher among patients with advanced T category tumors (Referent T1; T2a: OR 4.2, 95% CI 2.0-8.8, p < 0.001; T2b: OR 2.4, 95% CI 1.1-4.9, p = 0.018; T3: OR 3.6, 95% CI 1.6-7.9, p = 0.001; T4: OR 2.2, 95% CI 1.0-4.9, p = 0.049). In addition, the portion of patients with LNM varied among the different T categories (T1, 23.2%, T2a, 55.3%, T2b, 42.0%, T3, 51.4%, and T4, 39.5%; p = 0.001).Conclusions: Utilization of LND in the surgical management of ICC across the USA remained relatively low and did not change over the last decade. Selective utilization of LND may be problematic as T-stage was not a reliable predictor of nodal status with almost a quarter of patients with early stage disease having LNM. [ABSTRACT FROM AUTHOR]

Background: Patient-provider communication (PPC) is utilized as a value-based metric in pay-for-performance programs. We sought to evaluate the association of PPC with patient-reported health outcomes, as well as healthcare resource utilization among a nationally representative cohort of patients with hepato-pancreato-biliary (HPB) diagnoses.Methods: Patients with HPB diseases were identified from the 2008-2014 Medical Expenditure Panel Survey cohort. A weighted PPC composite score was categorized using the responses from the CAHPS (Consumer Assessment of Healthcare Providers and Systems) survey as optimal, average, or poor. Multivariate analysis was performed using logistic regression.Results: Among 1951 adult-patients, representing 21.7 million HPB patients, reported PPC was optimal (33.4%), average (46.3%), or poor (15.3%). Patients who were older and patients with low income were more likely to report poor PPC (both p < 0.05). Statin use, a quality of care measure, was associated with optimal PPC (OR 1.70, 95% CI 1.10-2.64; p = 0.01). In contrast, patients who reported poor PPC were more likely to have a poor physical (20.8%) or mental (8.8%) health component on their SF12 (both p < 0.05). Furthermore, patients with poor PPC were more likely to report poor mental status (OR 2.97, 95% CI 1.60-5.52), as well as higher emergency department visits (OR 1.95, 95% CI 1.25-3.05) and hospitalizations (OR 1.90, 95% CI 1.02-3.55) (both p < 0.05). Reported PPC was not associated with differences in overall healthcare expenditures or out-of-pocket expenditures.Conclusions: PPC was associated with a wide spectrum of patient-specific demographic and health utilization factors. Self-reported patient satisfaction with provider communication may be impacted by other considerations than simply the patient-provider interaction. [ABSTRACT FROM AUTHOR]

Background: Head and neck cancer (HNC) risk is elevated among lean people and reduced among overweight or obese people in some studies; however, it is unknown whether these associations differ for certain subgroups or are influenced by residual confounding from the effects of alcohol and tobacco use or by other sources of biases.Methods: We pooled data from 17 case-control studies including 12 716 cases and the 17 438 controls. Odds ratios (ORs) and 95% confidence intervals (CIs) were estimated for associations between body mass index (BMI) at different ages and HNC risk, adjusted for age, sex, centre, race, education, tobacco smoking and alcohol consumption.Results: Adjusted ORs (95% CIs) were elevated for people with BMI at reference (date of diagnosis for cases and date of selection for controls) < or =18.5 kg/m(2) (2.13, 1.75-2.58) and reduced for BMI >25.0-30.0 kg/m(2) (0.52, 0.44-0.60) and BMI > or =30 kg/m(2) (0.43, 0.33-0.57), compared with BMI >18.5-25.0 kg/m(2). These associations did not differ by age, sex, tumour site or control source. Although the increased risk among people with BMI < or =18.5 kg/m(2) was not modified by tobacco smoking or alcohol drinking, the inverse association for people with BMI > 25 kg/m(2) was present only in smokers and drinkers.Conclusions: In our large pooled analysis, leanness was associated with increased HNC risk regardless of smoking and drinking status, although reverse causality cannot be excluded. The reduced risk among overweight or obese people may indicate body size is a modifier of the risk associated with smoking and drinking. Further clarification may be provided by analyses of prospective cohort and mechanistic studies. [ABSTRACT FROM AUTHOR]

Background: Laboratory studies suggest that flavonoids are antimutagenic and anticarcinogenic. To investigate the associations between commonly consumed flavonoid compounds and lung cancer, the authors conducted a population-based case-control study of 558 lung cancer cases and a group of 837 controls.Methods: Dietary intakes of flavonoids were estimated by combining the intake frequency (collected by a food frequency questionnaire), portion size, and food composition data. Unconditional logistic regression analysis was used to estimate odds ratios (ORs) and 95% confidence limits (95% CLs) with an adjustment for potential confounders, including age, sex, race-ethnicity, years of schooling, smoking status, pack-years of tobacco smoking, and daily energy intake.Results: Lung cancer was associated inversely with the consumption of epicatechin (in 10 mg per day increment: OR, 0.64; 95% CL, 0.46-0.88), catechin (4 mg per day increment: OR, 0.49; 95% CL, 0.35-0.70), quercetin (9 mg per day increment: OR, 0.65; 95% CL, 0.44-0.95), and kaempferol (2 mg per day increment: OR, 0.68; 95% CL, 0.51-0.90) among tobacco smokers. There was little association between lung cancer and the flavonoid compounds mentioned above among nonsmokers. Regardless of smoking status, there was little association with total flavonoids: thearubigins, hesperetin, naringenin, and myricetin. In addition, consumption of vegetables, tea, and wine, all of which are rich sources of flavonoids, was associated inversely with lung cancer among tobacco smokers.Conclusions: Certain flavonoid compounds, including epicatechin, catechin, quercetin, and kaempferol, were associated inversely with lung cancer among tobacco smokers, but not among nonsmokers. Further studies of these associations may be warranted. [ABSTRACT FROM AUTHOR]

Objective: We investigated the association of diabetes diagnosis and medication type with liver injury in individuals with clinical diabetes. Methods: We analyzed 2426 patients with clinical diabetes in the National Health and Nutrition Examination Survey conducted from 1999 to 2008. Elevated alanine transaminase (ALT) and aspartate transaminase (AST) levels were used as markers of liver injury. Participants were categorized into one of three categories: 1) clinical diabetes without physician's diagnosis or diabetes medication; 2) diagnosed diabetes without diabetes medication; or 3) diagnosed diabetes with diabetes medication, further divided by classes of diabetes medications prescribed. We conducted logistic regression analysis to examine the relationship between diabetes diagnosis and medication type and elevated ALT and AST, adjusting for race/ethnicity, education, health insurance status, BMI category, alcohol consumption, physical activity, antihyperlipidemic agents, glycohemoglobin, C-reactive protein, viral hepatitis and liver disease. Results: Participants with undiagnosed diabetes were more likely to have elevated ALT and AST levels (OR = 1.82, 95% CI 1.47, 2.42; OR = 1.99, 95% CI 1.46, 2.71, respectively). In contrast, there was no association between specific diabetes medication (i.e., sulfonylureas, biguanides/thiazolidinediones) and elevated ALT or AST levels among the treated. Our findings were confirmed in sensitivity analyses employing a lower threshold for ALT, and excluding individuals with viral hepatitis or liver disease. Conclusion: We found that undiagnosed diabetes is associated with liver injury, compared to diagnosed diabetes with treatment. The effect of diabetes treatment on liver injury in individuals with diabetes remains uncertain. [ABSTRACT FROM AUTHOR]
