RESUMO

The present study aimed to elucidate the prognostic mutation signature (PMS) associated with long-term survival in a diffuse large B-cell lymphoma (DLBCL) cohort. All data including derivation and validation cohorts were retrospectively retrieved from The Cancer Genome Atlas (TCGA) database and whole-exome sequencing (WES) data. The Lasso Cox regression analysis was used to construct the PMS based on WES data, and the PMS was determined using the area under the receiver operating curve (AUC). The predictive performance of eligible PMS was analyzed by time-dependent receiver operating curve (ROC) analyses. After the initial evaluation, a PMS composed of 94 PFS-related genes was constructed. Notably, this constructed PMS accurately predicted the 12-, 36-, and 60-month PFS, with AUC values of 0.982, 0.983, and 0.987, respectively. A higher level of PMS was closely linked to a significantly worse PFS, regardless of the molecular subtype. Further evaluation by forest plot revealed incorporation of international prognostic index or tumor mutational burden into PMS increased the prediction capability for PFS. The drug-gene interaction and pathway exploration revealed the PFS-related genes were associated with DNA damage, TP53, apoptosis, and immune cell functions. In conclusion, this study utilizing a high throughput genetic approach demonstrated that the PMS could serve as a prognostic predictor in DLBCL patients. Furthermore, the identification of the key signaling pathways for disease progression also provides information for further investigation to gain more insight into novel drug-resistant mechanisms.

RESUMO

BACKGROUND AND AIMS: It is currently unclear whether the nonalcoholic fatty liver disease (NAFLD) fibrosis score, when compared to major anthropometric indices, is useful in estimating the risk of atherosclerotic cardiovascular disease (ASCVD). METHODS AND RESULTS: This study included 3886 adults undergoing a health checkup. An elevated risk of ASCVD was determined as a 10-year ASCVD risk ≥7.5% using Pooled Cohort Equations. NAFLD was diagnosed with abdominal ultrasonography. Receiver operating characteristic curves were used to evaluate the performance of estimating an elevated ASCVD risk. Among study participants, 521 (13.4%) had an elevated ASCVD risk and 1473 (37.9%) had NAFLD. Subjects with NAFLD had a significantly higher rate of ASCVD risk ≥7.5% (p < 0.001) compared to those without NAFLD. After adjusting for cardiometabolic risk factors, NAFLD (OR = 1.49, 95% CI: 1.10-2.00, p = 0.009) in all participants and NAFLD fibrosis score >0.676 (OR = 1.95, 95% CI: 1.30-2.92, p = 0.001) in individuals with NAFLD were significantly associated with an elevated risk of ASCVD. When compared to different anthropometric indices, NAFLD fibrosis score exhibited the largest area under the curve (AUC) in individuals with NAFLD (AUC = 0.750) in estimating an elevated ASCVD risk. Furthermore, NAFLD fibrosis score displayed the best predictive performance for identifying an elevated ASCVD risk in male participants with NAFLD (AUC = 0.737). CONCLUSION: NAFLD was a significant risk factor for elevated ASCVD risk. NAFLD fibrosis score >0.676 was associated with increased ASCVD risk in individuals with NAFLD. Compared with anthropometric indices, NAFLD fibrosis score demonstrated the best performance in estimating elevated ASCVD risk among those with NAFLD.

RESUMO

Cisplatin is a prevalent chemotherapeutic agent used for non-small cell lung cancer (NSCLC) that is difficult to treat by targeted therapy, but the emergence of resistance severely limits its efficacy. Thus, an effective strategy to combat cisplatin resistance is required. This study demonstrated that, at clinically achievable concentrations, the combination of selenium yeast (Se-Y) and fish oil (FO) could synergistically induce the apoptosis of cancer stem cell (CSC)-like A549 NSCLC sphere cells, accompanied by a reversal of their resistance to cisplatin. Compared to parental A549 cells, sphere cells have higher cisplatin resistance and possess elevated CSC markers (CD133 and ABCG2), epithelial-mesenchymal transition markers (anexelekto (AXL), vimentin, and N-cadherin), and cytoprotective endoplasmic reticulum (ER) stress marker (glucose-regulated protein 78) and increased oncogenic drivers, such as yes-associated protein, transcriptional coactivator with PDZ-binding motif, ß-catenin, and cyclooxygenase-2. In contrast, the proapoptotic ER stress marker CCAAT/enhancer-binding protein homologous protein and AMP-activated protein kinase (AMPK) activity were reduced in sphere cells. The Se-Y and FO combination synergistically counteracted the above molecular features of A549 sphere cells and diminished their elevated CSC-like side population. AMPK inhibition by compound C restored the side population proportion diminished by this nutrient combination. The results suggest that the Se-Y and FO combination can potentially improve the outcome of cisplatin-treated NSCLC with phenotypes such as A549 cells.

RESUMO

Purpose: The purpose of this study was to compare the chemical and physical properties of eight contemporary direct pulp capping materials. Methods: Materials included: calcium hydroxide-based (Dycal®, Lime-LiteTM, and Ultra-BlendTM plus), bioceramic-based (MTA Angelus®, Biodentine®, TheraCal LC®, Ceramir® Protect LC), and resin ionomer-based materials (Bio-Cap®). Calcium release and pH changes were measured after one, seven, 28, and 90 days in 36.8 degrees Celsius of deionized water. Water sorption and solubility were calculated with weight loss after 90 days. Results: Biodentine® (965.5 ppm) and MTA Angelus® (921.2 ppm) released significantly more cumulative calcium ions (P<0.05), followed by Ceramir® Protect LC (450.8 ppm) and Dycal® (268.1 ppm); Lime-LiteTM had the least amount of calcium ions. After 90 days, Biodentine® and MTA Angelus® showed significantly higher pH (P<0.05), while Bio-Cap® and Lime-LiteTM had limited effects in raising the pH to alkaline. Dycal® presented the most weight loss (26 percent, P<0.05) after 90 days. Conclusions: Biodentine® and MTA Angelus® demonstrated more favorable in vitro characteristics for clinical pulp capping purposes, while Lime-LiteTM had no effect in releasing calcium ions and limited influence in raising pH value.

RESUMO

Purpose: To evaluate early preventive dental services (PDS) provided by primary care providers (PCPs) in reducing future caries treatments among Alabama Medicaid recipients. Methods: Data from 2009 to 2019 Alabama Medicaid were used to evaluate effectiveness of 1st Look Program on PDS before age three years and incidence of caries treatments after age three years. PDS groups consisted of 1st Look-involved (PDS claims from PCPs), dentist-only (PDS claims from dental providers), and no early fluoride treatment participants (no PDS claims before age three years). Outcomes included frequency and expenditures of fluoride applications, simple restorations, and extensive treatments. Regression models were used to evaluate associations between PDS groups and outcomes while controlling for covariates. Results: Children in 1st Look- involved received more fluoride (3.0 versus 2.1 times; P<0.001) and were applied earlier (12.1 versus 22.9 months old; P<0.001) than dentist-only group. After adjusting for covariates, compared to dentist-only, 1st Look-involved group received earlier fluoride (beta value equals -11.1 months; 95 percent confidence interval [95% CI] equals -11.25 to -10.97) with greater frequency (incident rate ratio equals 1.49; 95% CI equals 1.47 to 1.51). Caries treatment counts were highest in dentist-only followed by 1st Look-involved and no early fluoride treatment groups in both simple restorations (2.7 versus 2.0 versus 0.2 times; P<0.001) and extensive treatments (2.8 versus 2.3 versus 0.2 times; P<0.001), which were consistent after adjusting for covariates. Conclusions: PDS were provided earlier by PCPs in Medicaid-qualified children, with reduced caries treatments on primary teeth, compared to PDS by dental providers only.

RESUMO

BACKGROUND: Unscheduled emergency department return visits (EDRVs) are key indicators for monitoring the quality of emergency medical care. A high return rate implies that the medical services provided by the emergency department (ED) failed to achieve the expected results of accurate diagnosis and effective treatment. Older adults are more susceptible to diseases and comorbidities than younger adults, and they exhibit unique and complex clinical characteristics that increase the difficulty of clinical diagnosis and treatment. Older adults also use more emergency medical resources than people in other age groups. Many studies have reviewed the causes of EDRVs among general ED patients; however, few have focused on older adults, although this is the age group with the highest rate of EDRVs. OBJECTIVE: This aim of this study is to establish a model for predicting unscheduled EDRVs within a 72-hour period among patients aged 65 years and older. In addition, we aim to investigate the effects of the influencing factors on their unscheduled EDRVs. METHODS: We used stratified and randomized data from Taiwan's National Health Insurance Research Database and applied data mining techniques to construct a prediction model consisting of patient, disease, hospital, and physician characteristics. Records of ED visits by patients aged 65 years and older from 1996 to 2010 in the National Health Insurance Research Database were selected, and the final sample size was 49,252 records. RESULTS: The decision tree of the prediction model achieved an acceptable overall accuracy of 76.80%. Economic status, chronic illness, and length of stay in the ED were the top three variables influencing unscheduled EDRVs. Those who stayed in the ED overnight or longer on their first visit were less likely to return. This study confirms the results of prior studies, which found that economically underprivileged older adults with chronic illness and comorbidities were more likely to return to the ED. CONCLUSIONS: Medical institutions can use our prediction model as a reference to improve medical management and clinical services by understanding the reasons for 72-hour unscheduled EDRVs in older adult patients. A possible solution is to create mechanisms that incorporate our prediction model and develop a support system with customized medical education for older patients and their family members before discharge. Meanwhile, a reasonably longer length of stay in the ED may help evaluate treatments and guide prognosis for older adult patients, and it may further reduce the rate of their unscheduled EDRVs.

RESUMO

The coronavirus disease 2019 (COVID-19) pandemic results in a profound physical and mental burden on healthcare professionals. This study aims to evaluate burnout status and mood disorder of healthcare workers during this period. An online questionnaire was voluntarily answered by eligible adult employees in a COVID-19 specialized medical center. The major analysis included the burnout status and mood disorder. Factors related to more severe mood disorder were also identified. A total of 2029 participants completed the questionnaire. There were 901 (44.4%) and 923 (45.5%) participants with moderate to severe personal and work-related burnout status, respectively. Nurses working in the emergency room (ER), intensive care unit (ICU)/isolation wards, and general wards, as well as those with patient contact, had significantly higher scores for personal burnout, work-related burnout, and mood disorder. This investigation identified 271 participants (13.35%) with moderate to severe mood disorder linked to higher personal/work-related burnout scores and a more advanced burnout status. Univariate analysis revealed that nurses working in the ER and ICU/isolation wards were associated with moderate to severe mood disorder risk factors. Multivariate analysis demonstrated that working in the ER (OR, 2.81; 95% CI, 1.14-6.90) was the only independent risk factor. More rest, perquisites, and an adequate supply of personal protection equipment were the most desired assistance from the hospital. Compared with the non-pandemic period (2019), employees working during the COVID-19 pandemic (2020) have higher burnout scores and percentages of severe burnout. In conclusion, this study suggests that the COVID-19 pandemic has had an adverse impact on healthcare professionals. Adequate measures should be adopted as early as possible to support the healthcare system.

RESUMO

This study aimed to investigate the performance of innovative and traditional cardiometabolic indices, including body mass index (BMI), waist circumference (WC), Chinese visceral adiposity index (CVAI), visceral adiposity index, lipid accumulation product, a body shape index (ABSI), body roundness index, conicity index (CI), triglyceride-glucose (TyG) index, TyG-BMI, and TyG-WC, in estimating atherosclerotic cardiovascular disease (ASCVD) risk in 3143 Taiwanese adults aged 20-79 years. Elevated 10-year ASCVD risk was defined as ≥7.5% using the Pooled Cohort Equations. The performance of different indices in estimating elevated ASCVD risk was assessed by receiver operating characteristic (ROC) curves. In multivariate-adjusted logistic regression analyses, all cardiometabolic indices (p-value < 0.001) were significantly associated with elevated ASCVD risk in both genders, except for ABSI and CI in women. In particular, CVAI had the largest area under the curve (AUC) in men (0.721) and women (0.883) in the ROC analyses. BMI had the lowest AUC in men (0.617), while ABSI had the lowest AUC in women (0.613). The optimal cut-off value for CVAI was 83.7 in men and 70.8 in women. CVAI performed best among various cardiometabolic indices in estimating elevated ASCVD risk. CVAI may be a reliable index for identifying people at increased risk of ASCVD.

RESUMO

BACKGROUND: Listening to music can be a noninvasive method for reducing the anxiety level without any adverse effects. The aim of this study was to explore whether music can reduce anxiety and to compare two different styles of music, informal classical music and light music, to ascertain the more effective style of music in reducing anxiety in patients undergoing colonoscopy without sedation. METHODS: This study enrolled 138 patients who underwent colonoscopy without sedation during a general health examination from February 2009 to January 2015. The patients were randomly assigned to a group that did not listen to music, a group that listened to music by David Tolley, or a group that listened to music by Kevin Kern. The State-Trait Anxiety Inventory was used to evaluate the status of anxiety. RESULTS: A trend test for mild anxiety was performed on the patients in the three groups, and a significant trend was noted (p=0.017 for all patients; p=0.014 for analysis by sex). Multivariate analysis for mild anxiety on the patients in each group was also performed in this study, and music by Kevin Kern was found to have the lowest odds ratio (Odds ratio=0.34, p=0.045). CONCLUSION: Listening to music, especially music by Kevin Kern, reduced the level of anxiety in patients undergoing colonoscopy examination without sedation.

RESUMO

Chronic infection by hepatitis C virus (HCV) is a major risk factor for the development of hepatocellular carcinoma (HCC). Despite the clear clinical importance of virus-associated HCC, the underlying molecular mechanisms remain largely unclarified. Oxidative stress, in particular, DNA lesions associated with oxidative damage, plays a major role in carcinogenesis, and is strongly linked to the development of many cancers, including HCC. However, in identifying hepatocytes with HCV viral RNA, estimates of the median proportion of HCV-infected hepatocytes have been found as high as 40% in patients with chronic HCV infection. In order to explore the gene alternation and association between different viral loads of HCV-infected cells, we established a method to dissect high and low viral load cells and examined the expression of DNA damage-related genes using a quantitative polymerase chain reaction array. We found distinct expression patterns of DNA damage-related genes between high and low viral load cells. This study provides a new method for future study on virus-associated gene expression research.

RESUMO

BACKGROUND: In the U.S. Renal Data System registry, technique and patient survival are similar with automated peritoneal dialysis (APD) and continuous ambulatory peritoneal dialysis (CAPD). The clinical outcomes of APD and CAPD in various age groups have not been clarified. OBJECTIVES: We investigated whether patient and technique survival are different for incident dialysis patients treated with APD or CAPD in two age groups. METHODS: Our retrospective study of prospectively collected data included 282 incident peritoneal dialysis (PD) patients (161 on APD, 121 on CAPD). Patients on PD for less than 3 months were excluded. The patients were divided into those less than 65 years of age and those 65 years of age or older. Overall mortality and technique failure were the primary endpoints of the study. Hazard ratios (HRs) for mortality and technique failure were calculated by the Cox proportional hazards model and were adjusted for age, sex, diabetes mellitus, initial peritoneal equilibration test (PET), weekly peritoneal and renal creatinine clearances, and PD caregiver (self or other). RESULTS: The characteristics and clinical data were not significantly different between patients on APD and CAPD, except for age and sex. The adjusted risk for overall mortality was not different between patients on APD and CAPD (HR: 0.72; 95% CI: 0.44 to 1.20; p = 0.207). The adjusted risk for technique failure was lower in APD patients than in CAPD patients (HR: 0.58; 95% CI: 0.34 to 0.98; p = 0.041). In patients less than 65 years of age, those on APD had a significantly lower risk of mortality (HR: 0.35; 95% CI: 0.16 to 0.75; p = 0.007) and technique failure (HR: 0.52; 95% CI: 0.28 to 0.95; p = 0.034) than did those on CAPD. In patients 65 years of age and older, those on APD had risks for mortality (HR: 1.14; 95% CI: 0.53 to 2.46; p = 0.730) and technique failure (HR: 0.51; 95% CI: 0.17 to 1.50; p = 0.220) that were similar to those of patients on CAPD. Nutrition status, including serum albumin and protein catabolic rate, was not significantly different between patients on APD and on CAPD, in either younger or older patients. CONCLUSIONS: Younger Chinese patients on APD have better patient and technique survival than do those on CAPD. However, there is a strong possibility that this benefit may be confounded or accounted for by baseline differences between the APD and CAPD populations.

RESUMO

A total of 274 Streptococcus dysgalactiae subsp. equisimilis isolates was analyzed by emm typing and by determining the organization of their mgrC loci. Three of the most frequent emm types were stG485.0 (45/274, 16.4%), stG6.1 (43/274, 15.7%), and stC839.0 (32/274, 11.7%), in decreasing order. The cpdB-positive mgrC locus appears to be predominant in some emm types.
