Infections with hepatitis C virus (HCV) represent a substantial national and international public health burden. HCV has been associated with numerous extrahepatic conditions and can lead to metabolic derangements that are associated with atherosclerosis and cardiovascular disease. We investigated whether HCV infection is associated with an increased number of acute coronary syndrome (ACS) events among hospitalized patients in an inner-city tertiary hospital.We performed a matched (age, sex, and race/ethnicity) case-control study on patients at least 18 years old admitted to inpatient medical and cardiac services at the University of Maryland Medical Center from 2015 through 2018. The primary outcome was ACS and the primary exposure was HCV infection. Covariates of interest included alcohol use, tobacco use, illicit drug use, hypertension, diabetes mellitus, human immunodeficiency virus infection, body mass index, dyslipidemia, and family history of coronary heart disease. Covariates with significant associere was no significant association found between experiencing an ACS event in those with HCV infection compared to those without HCV infection (odds ratio 0.71, 95% confidence interval 0.45-1.11).We found no significant association between HCV infection and ACS in our study population. However, given the mixed existing literature, the association between HCV and ACS warrants further investigation in future prospective cohort and/or interventional studies.
Previous studies were controversial about the role of psychosocial factors in the pathogenesis of esophageal cancer (EC). This study aimed to systematically evaluate the effect size of psychosocial risk factors for EC in Chinese cohort.A literature search was conducted in both English and Chinese databases, and odds ratios (OR) with the corresponding 95% confidence intervals (CI) were pooled using a random-effects model.28 studies were identified with a total of 6951 EC cases and 7469 controls. The meta-analysis indicated a higher risk of EC among the individuals with psychological trauma (OR 2.36, 95% CI 1.71-3.26), Type A behavior (OR 1.40, 95% CI 1.17-1.67), depression (OR 4.00, 95% CI 2.44-6.55), melancholy (OR 2.06, 95% CI 1.32-3.20), always in sulks (OR 2.49, 95% CI 1.21-5.12), and irritable personality (OR 2.13, 95% CI 1.58-2.89). A lower EC risk was found in the individuals with good interpersonal relationship (OR 0.35, 95% CI 0.17-0.70) and outgoing personality (OR 0.39, 95% CI 0.19-0.78).This meta5% CI 1.58-2.89). A lower EC risk was found in the individuals with good interpersonal relationship (OR 0.35, 95% CI 0.17-0.70) and outgoing personality (OR 0.39, 95% CI 0.19-0.78).This meta-analysis suggested a potential association between psychosocial factors and EC risk. For the individuals with psychosocial risk factors, physicians should pay more attention to EC screening.
To assess tocilizumab (TCZ) efficacy associated to standard of care (SOC) compared to SOC alone in severe coronavirus associated disease 2019 (COVID-19) patients. In a matched case-control study from 3 French Hospital COVID-19 Departments, 27 patients with severe COVID-19 treated with TCZ and SOC were matched for baseline epidemiological and clinical features and compared to 27 severe COVID-19 patients treated with SOC alone. Baseline characteristics of the study population were comparable between groups. Eleven patients (20%) died. TCZ was not associated with clinical improvement as compared to SOC regarding oxygen-free status (44% vs 63%) and death (18.5% vs 22%), despite a higher decrease of the C-reactive protein at Day 7 (10.7 vs 52 mg/L; P < 10-3). Compared to the 43 patients alive at the end-of follow-up, patients who died were older (78 vs 64 years; P < 10-3), with 82% of them older than 72 years vs only 23% of live patients (P < 10-3). Age (OR = 1.15; 95%CI = 1.04-1.3; P = .008) and age ovical improvement as compared to SOC regarding oxygen-free status (44% vs 63%) and death (18.5% vs 22%), despite a higher decrease of the C-reactive protein at Day 7 (10.7 vs 52 mg/L; P  less then  10-3). Compared to the 43 patients alive at the end-of follow-up, patients who died were older (78 vs 64 years; P  less then  10-3), with 82% of them older than 72 years vs only 23% of live patients (P  less then  10-3). Age (OR = 1.15; 95%CI = 1.04-1.3; P = .008) and age over 72 years (OR) = 14.85; 95%CI = 2.7-80; P = .002) were independently associated with mortality. TCZ in addition to SOC for severe COVID-19 patients did not reduce mortality, subsequent need for invasive mechanical ventilation nor did it shorten the time of oxygen support, despite better control of the inflammatory response. More powerful and randomized controlled trials are warranted to determine if TCZ is effective in the management of COVID-19.
Skin melanoma remains a highly prevalent and yet deadly form of cancer, with the exact degree of melanoma-associated mortality being strongly dependent upon the local tumor microenvironment. The exact composition of stromal and immune cells within this microenvironmental region has the potential to profoundly impact melanoma progression and prognosis. As such, the present study was designed with the goal of clarifying the predictive relevance of stromal and immune cell-related genes in melanoma patients through comprehensive bioinformatics analyses. We therefore analyzed melanoma sample gene expression within The Cancer Genome Atlas database and employed the ESTIMATE algorithm as a means of calculating both stromal and immune scores that were in turn used for identifying differentially expressed genes (DEGs). Rapamycin datasheet Subsequently, univariate analyses were used to detect DEGs associated with melanoma patient survival, and through additional functional enrichment analyses, we determined that these survival-related DEited distinct immune statuses and differing degrees of immune cell infiltration. In conclusion, our results offer novel insights into a number of microenvironment-associated genes that impact survival outcomes in melanoma patients, potentially highlighting these genes as viable therapeutic targets.
The purpose of this study was to determine the glucose metabolism at delay phase measured by pretreatment dual-time-point 18F-fluorodeoxyglucose (18F-FDG) positron emission tomography (PET)/ computed tomography (CT) provides prognostic information independent of well-known prognostic factors in patients with intrahepatic or perihilar cholangiocarcinoma (ICC or PCC).From July 2012 to December 2017, 55 patients (men 27, women 28, mean age 68 ± 11 years) with pathologically proven ICC or PCC were enrolled in this retrospective study. The dual-time-point 18F-FDG PET/CT as part of a staging workup was performed in all patients. The patient's data includes age, sex, serum CA19-9, presence of LN or distant metastasis, early SUVmax (early maximum standardized uptake value [eSUV]), delay SUVmax (delay maximum standardized uptake value [dSUV]), retention index of SUVmax (percent change of maximum standardized uptake values [ΔSUV]), neutrophil to lymphocyte ratio (NLR) and histopathology including pCEA, p53, Ki-67 inds then  .001) among the comparisons of the SUV parameters on FDG PET. In the receiver operating characteristic analysis using combinations of the SUV parameters, the 2 groups [eSUV + ΔSUV (P = .0001, area under the curve [AUC] 0.68) and dSUV + ΔSUV (P = .0002, AUC 0.71)] showed significantly larger AUC than the other groups applying eSUV or dSUV alone (AUC 0.61 and AUC 0.68).dSUV and ΔSUV on pretreatment dual-time-point 18F-FDG PET/CT can be useful parameters in the prediction of survival in patients with ICC or PCC.
Radiation enteritis (RE) is a common complication that often occurs after radiotherapy for abdominal and pelvic malignancies. RE could influence patients' quality of life seriously and it is difficult to cure by conventional treatments. A lot of studies have revealed that the external treatment of traditional Chinese medicine (TCM) for RE is a safe and economical approach, but there is no relevant systematic review. The present study performed a systematic review and meta-analysis to compare TCM external treatment and conventional treatment for RE to evaluate the effectiveness and safety of external treatment of traditional Chinese medicine in the treatment of RE.

Cochrane Library, PubMed, Embase, China National Knowledge Infrastructure (CNKI), Wan-Fang database, VIP Chinese Science and Technique Journals Database, and the Chinese Biomedical Literature Database (CBM) were searched. The time of publication was limited from inception to April, 2021. Two reviewers independently searched for the selected articles and extract the data. The RevMan V.5.3 statistical software (Cochrane Collaboration) and Stata V.16.0 software were used to conduct the meta-analysis.

We will show the results of this study in a peer-reviewed journal.

This meta-analysis will provide reliable evidence for external treatment of TCM in the treatment of RE.

Chronic obstructive pulmonary disease (COPD) is a common respiratory disease that is associated with significant morbidity and mortality. Exercise training confers health benefits to people with COPD. The purpose of this study was to compare differences in the rehabilitation of COPD between Qigong exercise (QE) and aerobic exercise using a cycle ergometer (CE).

This study was a randomized single-blind controlled trial. Twenty six participants were recruited and randomized to either the Qigong group or the cycle ergometer group. Both interventions lasted 12 weeks and comprised a 30 minutes supervised training session performed twice a week, that is, 24 sessions in total. The primary outcome measure was the endurance capacity measured by the six-minute walk test (6MWT). The secondary outcome measures were the results of the St. George's Hospital Respiratory Questionnaire (SGRQ) and the COPD assessment test (CAT).

Participants in the group that performed aerobic exercise using a cycle ergometer had significantly improved 6MWT (P = .005), SGRQ (P = .029), and CAT (P = .018) results. Participants in the Qigong exercise group had significant changes in 6MWT (P = .033). However, the differences in 6MWT and SGRQ were not statistically significant between the 2 groups. The changes in CAT scores before and after the intervention were significantly different between the 2 groups (P = .020). There were no reports of adverse events during the course of the trial.

There was no difference in the primary outcome between groups. In particular, QE and cycle ergometer exercise had similar rehabilitation effects on the improvement of the cardiopulmonary endurance and quality of life of chronic obstructive pulmonary disease patients. In addition, cycle ergometer exercise may lead to a better trend of improvement in the quality of life and can improve the severity of the clinical symptoms of chronic obstructive pulmonary disease.

Chronic kidney disease (CKD)-associated pruritus (CKD-aP) contributes to poor quality of life, including reduced sleep quality and poor sleep quality is a source of patient stress and is linked to lower health-related quality of life. This study aimed to investigate the effectiveness of zolpidem 10 mg and acupressure therapy on foot acupoints to improve the sleep quality and overall quality of life among hemodialysis patients suffering from CKD-aP.

A multicenter, prospective, randomized, parallel-design, open label interventional study to estimate the effectiveness of zolpidem (10 mg) oral tablets versus acupressure on sleep quality and quality of life in patients with CKD-aP on hemodialysis. A total of 58 hemodialysis patients having sleep disturbance due to CKD-aP completed the entire 8-week follow-up. The patients were divided into a control (acupressure) group of 28 patients and an intervention (zolpidem) group of 30 patients.

A total of 58 patients having CKD-aP and sleep disturbance were recruited.
