RESUMO

Evidence supports an association between religion and spirituality and health outcomes. The aim of this study is to examine religious beliefs related to health and their relationship to self-rated health in a large and diverse population-based sample in Chicago. Three religious beliefs were assessed-the importance of prayer for health, God's will as the most important factor in getting well, and sanctity of the body. All three beliefs were highly prevalent, especially among racial/ethnic minorities. Unadjusted models showed a significant association between two of the beliefs and self-rated health, which did not persist in the adjusted models. This study provides insight into different belief patterns among racial/ethnic groups and has practical implications for both clinicians and public health practitioners.

RESUMO

Objectives Child care is an important setting for the promotion of physical activity (PA) in early childhood. The purpose of this study was to examine the associations between specific PA environments and recommended practices in child care settings as well as the degree to which child care settings met recommended standards for total PA time. Methods In 2013, all programs licensed to care for children ages 2-5 in WA state were surveyed about their PA related practices. Logistic regression was used to determine odds of meeting best-practice standards for outdoor time and PA. Results The response rate was 45.8 % from centers (692/1511) and 32.1 % from homes (1281/3991). Few programs reported meeting best-practice standards for the amount of time children spend being physically active (centers: 12.1 %, homes: 20.1 %) and outdoor time (centers: 21.8 %, homes: 21.7 %). Programs where children go outside regardless of weather and those reporting more adult-led PA had higher odds of meeting best-practice standards for both PA and outdoor time. Meeting best-practice standards for outdoor time was the strongest predictor of meeting best-practice standards for total PA time [centers: OR 15.9 (9.3-27.2), homes: OR 5.2 (3.8-7.1)]. Conclusions for Practice There is considerable room for improvement in licensed child care settings in WA to meet best-practice standards for young children's outdoor and PA time. Initiatives that create policies and environments encouraging outdoor play and adult-led PA in child care have the potential to increase physical activity in substantial numbers of young children.

RESUMO

Acute kidney injury (AKI) is one of the leading causes of in-hospital morbidity and mortality, particularly in critically ill patients. Although our understanding of AKI at the molecular level remains limited due to its complex pathophysiology, recent advances in both quantitative and spatial mass spectrometric approaches offer new opportunities to assess the significance of renal metabolomic changes in AKI models. In this study, we evaluated lipid changes in early ischemia-reperfusion (IR)-related AKI in mice by using sequential window acquisition of all theoretical spectra (SWATH)-mass spectrometry (MS) lipidomics. We found a significant increase in two abundant ether-linked phospholipids following IR at 6 h postinjury, a plasmanyl choline, phosphatidylcholine (PC) O-38:1 (O-18:0, 20:1), and a plasmalogen, phosphatidylethanolamine (PE) O-42:3 (O-20:1, 22:2). Both of these lipids correlated with the severity of AKI as measured by plasma creatinine. In addition to many more renal lipid changes associated with more severe AKI, PC O-38:1 elevations were maintained at 24 h post-IR, while renal PE O-42:3 levels decreased, as were all ether PEs detected by SWATH-MS at this later time point. To further assess the significance of this early increase in PC O-38:1, we used matrix-assisted laser desorption ionization imaging mass spectrometry (MALDI-IMS) to determine that it occurred in proximal tubules, a region of the kidney that is most prone to IR injury and also rich in the rate-limiting enzymes involved in ether-linked phospholipid biosynthesis. Use of SWATH-MS lipidomics in conjunction with MALDI-IMS for lipid localization will help in elucidating the role of lipids in the pathobiology of AKI.

RESUMO

Background: Long lasting insecticide-treated bednets (LLINs) are the most widely used tool for preventing malaria. There has been a plateau in progress in the highest burden African countries since 2015, leading to questions about the effectiveness of LLINs. In this study, remote LLIN use monitors were deployed in a cohort in Eastern Uganda to explore how LLIN use interacts with mosquito exposure. Methods: The SmartNet study included 20 households from May to October 2019. SmartNet devices recorded, every 15 min, whether an LLIN was unfurled or folded up. Unannounced visits were used to assess SmartNet accuracy. Risk factors associated with poor LLIN use were assessed using generalized linear equations. Female Anopheles exposure was estimated by combining hourly probabilities of exposure from human landing catches and measures of density from biweekly CDC light traps in participants rooms. Mosquito exposure averted by LLINs was quantified using SmartNet measurements and age-related differences were estimated using generalized linear equations, adjusting for relevant covariates and household clustering. Results: 96 individuals contributed 5,640 SmartNet observation nights. In 126 unannounced visits, SmartNet had an area under the curve of 0.869 in classifying whether the LLIN was up or down. The rate of non-use was 13.5% of nights (95% CI: 12.6-14.3%). Compared to children under 5, non-use was 1.8 times higher (95% CI: 1.6-2.1; p < 0.001) in children 5-15 years and 2.6 times higher (95% CI: 2.2-3.1; p < 0.001) in participants aged 15-<30years. There was no difference between children under 5 years and adults > 30 years. LLIN use averted 50.3% of female Anopheles mosquito exposure (95% CI: 40.0-60.0%), with decreasing point estimates of efficacy across age groups: from 61.7% (95% CI: 42.6-80.7%) in children under 5 years to 48.0% (95% CI: 29.1-66.8%) in adults over 30. Conclusions: Objective monitors are accurate and can feasibly be deployed to obtain data about LLIN use. LLINs provided protection from only 50% of female Anopheles mosquito exposure in this cohort and protection was dependent upon age. In assessing the role of LLINs in malaria prevention it is crucial to consider the dynamics between mosquito exposure and LLIN use behaviors.

RESUMO

We recently reported the development of a multianalyte serum algorithm to identify nodal status in non-small cell lung cancer (NSCLC) patients facing an anatomic resection with curative intent. This study aims to enhance the overall performance characteristics of this test by adding autoantibody biomarkers identified through immunoproteomic discovery. More specifically, we used sera from 20 NSCLC patients to probe 2-D immunoblots of HCC827 lysates for tumor-associated autoantigens. Relevant differences in immunoreactivity associated with pathological nodal status were then identified via tandem mass spectrometry. Identified autoantigens were then developed into Luminex immunobead assays alongside a series of autoantigen targets relevant to early-disease detection. These assays were then used to measure circulating autoantibody levels in the identical cohort of NSCLC patients used in our original study. This strategy identified 11 autoantigens found primarily in patients with disease progression to the locoregional lymph nodes. Custom Luminex-based "direct-capture" assays (25 total; including autoantibody targets relevant to early-disease detection) were assembled to measure autoantibody levels in sera from 107 NSCLC patients. Multivariate classification algorithms were then used to identify the optimal combination of biomarkers when considered collectively with our original 6-analyte serum panel. The new algorithm resulting from this analysis consists of TNF-α, TNF-RI, MIP-1α and autoantibodies against Ubiquilin-1, hydroxysteroid-(17-ß)-dehydrogenase, and triosephosphate isomerase. The inclusion of autoantibody biomarkers provided a dramatic improvement in the overall test performance characteristics, relative to the original test panel, including an 11% improvement in the classification efficiency.

RESUMO

The primary objective of this study is to identify prognostic site-specific epigenetic changes in surgically treated Stage I and II nonsmall cell lung cancer (NSCLC) patients by quantifying methylation levels at multiple CpG sites within each gene promoter. Paraffin-embedded tumors from stage Ib, IIa and IIb in training and validation groups of 75 and 57 surgically treated NSCLC patients, respectively, were analyzed for p16, MGMT, RASSF1, RASSF5, CDH1, LET7, DAPK and PTEN promoter hypermethylation. Hypermethylation status was quantified individually at multiple CpG sites within each promoter by pyrosequencing. Molecular and clinical characteristics with time to recurrence (TTR) and overall survival (OS) were evaluated. Overall average promoter methylation levels of MGMT and RASSF1 were significantly higher in smokers than in nonsmokers (p = 0.006 and p = 0.029, respectively). Methylation levels of the p16 promoter were significantly higher in squamous cell carcinoma than in adenocarcinoma (p = 0.020). In univariate analysis, hypermethylation of RASSF1 at CpG sites -53 and -48 and PTEN at CpG site -1310 were the significantly associated with shorter TTR (p = 0.002 and p < 0.000, respectively). Hypermethylation of PTEN at -1310 and DAPK at -1482 were most significantly associated with outcome in multivariate analysis. These results show that methylation of specific promoter CpG sites in PTEN, RASSF1 and DAPK is associated with outcome in early stage surgically treated NSCLC.

RESUMO

INTRODUCTION: Amazon's Mechanical Turk (MTurk) is frequently used to administer health-related surveys and experiments at a low cost, but little is known about its representativeness with regards to health status and behaviors. METHODS: A cross-sectional survey comprised of questions from the nationally-representative 2014 Behavioral Risk Factor Surveillance System (BRFSS) and 2014 National Health and Nutrition Examination Survey (NHANES) was administered to 591 MTurk workers and 393 masters in 2016. Health status (asthma, depression, BMI, and general health), health behaviors (influenza vaccination, health insurance, smoking, and physical activity), and demographic characteristics of the two MTurk populations (workers and masters) were compared to each other and, using Poisson regression, to a nationally-representative BRFSS and NHANES samples. RESULTS: Workers and master demographics were similar. MTurk users were more likely to be aged under 50 years compared to the national sample (86% vs. 55%) and more likely to complete a college degree than the national sample (50% vs. 26%). Adjusting for covariates, MTurk users were less likely to be vaccinated for influenza, to smoke, to have asthma, to self-report being in excellent or very good health, to exercise, and have health insurance but over twice as likely to screen positive for depression relative to a national sample. Results were fairly consistent among different age groups. CONCLUSIONS: MTurk workers are not a generalizable population with regards to health status and behaviors; deviations did not follow a trend. Appropriate health-related uses for MTurk and ways to improve upon the generalizability of MTurk health studies are proposed.

RESUMO

BACKGROUND: To examine feasibility and initial efficacy of having previously treated parents serve as peer interventionists in family-based behavioral weight management treatment (FBT). METHODS: Children aged 7-11 years with overweight/obesity and parents (n = 59 families) were enrolled in one of two pilot trials, the EPICH (Engaging Parents in Child Health) randomized trial comparing professional versus peer FBT delivery or the Parent Partnership trial, which provided professionally delivered FBT to families (first generation) and then randomly assigned first generation parents to either be or not be peer interventionists for subsequent families (second generation). Efficacy (child zBMI change), feasibility, and costs for delivering FBT, and impacts of being a peer interventionist were examined. RESULTS: In EPICH, families receiving professional versus peer intervention had similar decreases in child zBMI and parent BMI, with markedly lower costs for peer versus professional delivery. In Parent Partnership, families receiving peer intervention significantly decreased weight status, with very preliminary evidence suggesting better maintenance of child zBMI changes if parents served as peer interventionists. Previously treated parents were willing, highly confident, and able to serve as peer interventionists in FBT. CONCLUSIONS: Two pilot randomized clinical trials suggest parents-as-peer interventionists in FBT may be feasible, efficacious, and delivered at lower costs, with perhaps some additional benefits to serving as a peer interventionist. More robust investigation is warranted of peer treatment delivery models for pediatric weight management.

RESUMO

The aim of this study was to retrospectively analyze the clinical data of resected adenosquamous lung cancer (ASLC) and to explore the influencing factors and clinicopathological characteristics of the metastasis lymph nodes. A total of 1156 consecutive patients with surgically resected lung cancer from January 2009 to June 2014 were studied. Fifty-four previously diagnosed ASLC patients were re-evaluated by experienced pathologists. IHC and H&E staining were employed to examine the primary focus and metastasis lymph nodes. The relationship between lymph node metastasis and clinicopathological characteristics of ASLC patients was then analyzed and the pathological type of metastasis lymph node was also determined. Forty-nine cases of typical ASLC were included in the study. Of the 49 ASLC patients, 26 cases presented lymph node metastasis. Lymph node metastasis was not associated with gender, smoking, tumor distribution, histological type of primary focus, and preoperative CEA level, but was associated with age ≥ 65 (P < .05) and tumor size ≥ 3 cm (P < .05). Lymph node metastasis adenocarcinoma was the main type in ASLC patients, and was related to the age and tumor size of the primary focus. Further large sample studies are necessary to identify influencing factors and clinicopathological characteristics of metastasis lymph nodes.

RESUMO

Although the incidence of breast cancer in the United States is higher in Caucasian women compared with African American women, African-American patients have more aggressive disease as characterized by a higher percentage of triple-negative breast cancers (TNBCs), high-grade tumors, and a higher mortality rate. PKCα is a biomarker associated with endocrine resistance and poor prognosis and ERß is emerging as a protective biomarker. Immunohistochemical analysis of ERß and PKCα expression was performed on 198 formalin-fixed paraffin-embedded primary infiltrating ductal carcinomas from 105 African-American and 93 Caucasian patients. PKCα is positively correlated with TNBC in patients of both races and with high tumor grade in African-American patients. Patients with TNBC express less nuclear ERß compared with all other subtypes. We find no difference in frequency or intensity of PKCα or ERß expression between African-American and Caucasian patients. PKCα and ERß are discussed as potential therapeutic targets for the treatment of patients with TNBC.

RESUMO

BACKGROUND: Insulin-like growth factor receptor 1 (IGF1R) is a proposed mechanism of resistance to epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors. Newer agents targeting this pathway make it of clinical interest. This study evaluates the IGF1R expression in regard to outcomes and molecular markers of EGFR activity in lung cancer patients treated with gefitinib. MATERIALS AND METHODS: Gefitinib-treated patients with sufficient archived tissue were included. The IGF1R activity was measured by immunohistochemistry and the EGFR by immunohistochemistry, fluorescent in situ hybridization, and gene mutation testing. Logistic regression and cox proportional hazards models were used. RESULTS: A total of 83 patients were included in the study: 71% were positive for IGF1R expression which was not associated with EGFR parameters or clinical outcomes. Exploratory analyses showed counter-intuitive improved outcomes with co-expression of IGF1R and EGFR. CONCLUSION: IGF1R expression measured by immunohistochemistry does not appear to be related to gefitinib resistance.

RESUMO

INTRODUCTION: In non-small cell lung cancer (NSCLC), the presence of locoregional lymph node metastases remains the most important prognostic factor and significantly guides treatment regimens. Unfortunately, currently-available noninvasive staging modalities have limited accuracy. The objective of this study was to create a multianalyte blood test capable of discriminating a patient's true (pathologic) nodal status preoperatively. METHODS: Pretreatment serum specimens collected from 107 NSCLC patients with localized disease were screened with 47 biomarkers implicated in disease presence or progression. Multivariate statistical algorithms were then used to identify the optimal combination of biomarkers for accurately discerning each patient's nodal status. RESULTS: We identified 15 candidate biomarkers that met our criteria for statistical relevance in discerning a patient's preoperative nodal status. A 'random forest' classification algorithm was used with these parameters to define a 6-analyte panel, consisting of macrophage inflammatory protein-1alpha, carcinoembryonic antigen, stem cell factor, tumor necrosis factor-receptor I, interferon-gamma, and tumor necrosis factor-alpha, that was the optimum combination of biomarkers for identifying a patient's pathologic nodal status. A Classification and Regression Tree analysis was then created with this panel that was capable of correctly classifying 88% of the patients tested, relative to the pathologic assessments. This value is in contrast to our observed 85% classification rate using conventional clinical methods. CONCLUSIONS: This study establishes a serum biomarker panel with efficacy in discerning preoperative nodal status. With further validation, this blood test may be useful for assessing nodal status (including occult disease) in NSCLC patients facing tumor resection therapy.
