Prognostic analysis of sex and age in hepatocellular carcinoma: a SEER study.

OBJECTIVES: This study aimed to explore the impact of sex on clinical features and survival among hepatocellular carcinoma (HCC) patients. METHODS: HCC case data from the Surveillance, Epidemiology, and End Results (SEER) database for the period 2010 to 2015 were selected for analysis. Kaplan-Meier curves displayed overall survival. Univariate cox regression examined the prognostic characteristics of individual features, and multivariate Cox regression assessed hazard ratios. RESULTS: This study comprised 3486 HCC patients, with 2682 males and 804 females. Across all age groups, there was a higher prevalence of males compared to females. Survival curves among female patients showed no significant differences across various age groups. However, among male patients, those under 60 demonstrated notably higher survival rates compared to those aged 60 and above. Regarding various ethnicities, TNM staging systems, tumor sizes, the presence of lung/bone/brain metastases, location in Purchased/Referred Care Delivery Areas, SEER historic stages, tumor grades, and individuals receiving chemotherapy, the proportion of male patients consistently exceeded that of female patients. Within the female patient group, individuals receiving chemotherapy exhibited significantly higher survival rates compared to those who did not. However, the administration of chemotherapy showed no significant impact on the survival rate of male patients. Multivariate Cox regression analysis revealed age, gender, and the administration of chemotherapy key factors influencing the overall survival prognosis. CONCLUSION: Age, gender, and the administration of chemotherapy are influential factors in the prognosis of both male and female HCC patients.

Molecular mechanisms underlying Tao-Hong-Si-Wu decoction treating hyperpigmentation based on network pharmacology, Mendelian randomization analysis, and experimental verification.

CONTEXT: Hyperpigmentation, a common skin condition marked by excessive melanin production, currently has limited effective treatment options. OBJECTIVE: This study explores the effects of Tao-Hong-Si-Wu decoction (THSWD) on hyperpigmentation and to elucidate the underlying mechanisms. MATERIALS AND METHODS: We employed network pharmacology, Mendelian randomization, and molecular docking to identify THSWD's hub targets and mechanisms against hyperpigmentation. The Cell Counting Kit-8 (CCK-8) assay determined suitable THSWD treatment concentrations for PIG1 cells. These cells were exposed to graded concentrations of THSWD-containing serum (2.5%, 5%, 10%, 15%, 20%, 30%, 40%, and 50%) and treated with α-MSH (100 nM) to induce an in vitro hyperpigmentation model. Assessments included melanin content, tyrosinase activity, and Western blotting. RESULTS: ALB, IL6, and MAPK3 emerged as primary targets, while quercetin, apigenin, and luteolin were the core active ingredients. The CCK-8 assay indicated that concentrations between 2.5% and 20% were suitable for PIG1 cells, with a 50% cytotoxicity concentration (CC50) of 32.14%. THSWD treatment significantly reduced melanin content and tyrosinase activity in α-MSH-induced PIG1 cells, along with downregulating MC1R and MITF expression. THSWD increased ALB and p-MAPK3/MAPK3 levels and decreased IL6 expression in the model cells. DISCUSSION AND CONCLUSION: THSWD mitigates hyperpigmentation by targeting ALB, IL6, and MAPK3. This study paves the way for clinical applications of THSWD as a novel treatment for hyperpigmentation and offers new targeted therapeutic strategies.

Efficacy and safety of visually guided laser balloon versus cryoballoon ablation for paroxysmal atrial fibrillation: a systematic review and meta-analysis.

Background: Newly developed catheter ablation (CA) techniques, such as laser balloon ablation (LBA) and cryoballoon ablation (CBA), have been introduced in recent years and emerged as valuable alternatives to conventional radiofrequency CA strategies for paroxysmal atrial fibrillation (PAF) patients. However, evidence comparing LBA and CBA remain controversial. Thus, we conducted this meta-analysis to assess the efficacy and safety between these two techniques. Methods: Scientific databases (PubMed, Embase) and relevant websites (the Cochrane Library, ClinicalTrials.gov) were systematically searched from inception to March 2023. The primary outcomes of interest were the AF recurrence and the procedure-related complications. Secondary outcomes included procedural time, fluoroscopy time, and left atrial (LA) dwell time. Results: Seven clinical trials with a total of 637 patients were finally enrolled. No significant differences were found between LBA and CBA in terms of AF recurrence [16.3% vs. 22.7%, odds ratio (OR) = 0.66, 95% confidence interval (CI): 0.42-1.05, p = 0.078] or total procedural-related complications (8.4% vs. 6.4%, OR = 1.33, 95% CI: 0.71-2.51, p = 0.371). LBA had a significantly longer procedural time [weighted mean difference (WMD) = 38.03 min, 95% CI: 13.48-62.58 min, p = 0.002] and LA dwell time (WMD = 46.67 min, 95% CI: 14.63-78.72 min, p = 0.004) than CBA, but tended to have shorter fluoroscopy time. Conclusions: LBA and CBA treatment have comparable efficacy and safety for PAF patients. LBA was associated with longer procedural and LA dwell times compared with CBA. Further large-scale studies are warranted to compare these two techniques with the newest generations.Systematic Review Registration: https://www.crd.york.ac.uk/prospero/display_record.php?RecordID=426513, identifier (CRD42023426513).

Effects of Ipratropium Bromide Combined with Traditional Chinese Medicine Intervention on the Pulmonary Function and Psychological Status of Patients with Chronic Obstructive Pulmonary Disease.

Recently, most scholars have advocated multidisciplinary comprehensive intervention measures for chronic obstructive pulmonary disease (COPD) to improve lung function, relieve symptoms of dyspnea, and improve quality of life. Traditional Chinese medicine (TCM) has rich experience in the treatment of various respiratory system diseases and the rehabilitation of their syndrome differentiation. In this study, total 68 patients with COPD from November 2019 to November 2021 in the hospitals were divided into the control group, ipratropium bromide (IB)-treated group, and IB + TCM-treated group for clinical efficacy observation and to explore the effect of IB combined with TCM on the pulmonary function and psychological status of COPD patients. Patients in the control group were subjected to routine oxygen inhalation, cough and expectorant, and antiviral treatments, while the patients in the IB-treated group were treated with IB and those received in the control group. Patients in the IB + TCM-treated group were treated with IB and TCM intervention. All patients were treated for a month. The results showed that after different interventions, the levels of FEV1, FEV1% pred, FVC, and PEF (P < 0.05) were significantly increased in all the groups, while levels of TNF-α, IL-6, IL-8, and CRP in serum as well as Hamilton Anxiety Scale and Hamilton Depression scores were significantly decreased. Compared with the control group and IB-treated group, the IB + TCM-treated group presented the greatest changes on all abovementioned indicators and the lowest total incidence of adverse reactions, indicating the biggest improvement of IB + TCM on the symptoms of COPD patients. Therefore, the combination of IB and TCM intervention effectively improved the pulmonary function and psychological status of COPD patients and could be used as an important adjunct for COPD treatment.

Hepatitis E virus superinfection impairs long-term outcome in hospitalized patients with hepatitis B virus-related decompensated liver cirrhosis.

INTRODUCTION AND OBJECTIVES: Hepatitis E virus (HEV) superinfection is a common excerbating event in patients with chronic hepatitis B, but the impact on the long-term prognosis is not clear. This study investigates the specific role of HEV superinfection in the long-term outcome of hepatitis B virus (HBV) patients with liver cirrhosis. PATIENTS AND METHODS: A retrospective, observational cohort study was conducted using clinical, laboratory, and survival data collected from patients suffering from hepatitis B cirrhosis with or without HEV superinfection. Disease progression and mortality rates were analyzed. RESULTS: After a two-year follow-up, HEV superinfection was identified in 27 of 811 patients. The transplantation-free mortality was significantly increased (51.9% vs. 14.3%, p< 0.001) in HEV superinfection compared to that in hepatitis B cirrhosis patients without HEV superinfection. Logistic regression analysis demonstrated that elderly people were independent host risk factors for hepatitis B cirrhosis patients with HEV superinfection before and after propensity score matching (PSM). Moreover, HEV superinfection was a risk factor for patients with hepatitis B cirrhosis with new acute decompensation (AD) and acute-on-chronic liver failure (ACLF) during hospitalization. A multivariate Cox proportional hazards regression model demonstrated that acute HEV co-infection is associated with two-year mortality (hazard ratio [HR]: 2.49; 95% CI: 1.40-4.43; p= 0.002; and HR: 5.79; 95% CI: 1.87-17.87; p= 0.002) in patients with hepatitis B cirrhosis before and after PSM. CONCLUSIONS: Elder patients with hepatitis B cirrhosis are susceptible to HEV superinfection, accelerating disease progression and increasing long-term mortality in hospitalized patients with HBV-related decompensated liver cirrhosis.

Vaccination with SARS-CoV-2 inactivated vaccines reduced the risk of anxiety and depression in a population majored by health care workers during the recent omicron variant outbreak.

Background: The mental health status of the population majored by health care workers in China during the omicron variant outbreak remains unknown. Furthermore, the effect of COVID-19-inactivated vaccines on mental health is yet to be investigated. Methods: A cross-sectional, online survey study was conducted from 12-20 April, 2022. The prevalence of symptoms of depression and anxiety were evaluated using the Hospital Anxiety and Depression Scale. Results: Responses from a total of 1,387 participants were analyzed, 39.7% of which reported symptoms of mental health illness. The incidence of anxiety (30.4% vs. 48.4%, p < 0.001) and depression (27.1% vs. 46.3%, p < 0.001) decreased with COVID-19 inactivated vaccination. From multivariate analysis, living in Shanghai (anxiety: Odds ratio [OR]: 1.58, 95% confidence interval [CI]: 1.14-2.19, p = 0.006; depression: OR: 1.61, 95% CI: 1.16-2.25, p = 0.005), with a mental illness (anxiety: OR: 8.97, 95% CI: 1.01-79.56, p = 0.049; depression: OR: 9.32, 95% CI: 1.06-82.30, p = 0.045) increased the incidence of anxiety and depression. Elderly participants (anxiety: OR: 0.986, 95% CI: 0.975-0.997, p = 0.012; depression: OR: 0.976, 95% CI: 0.965-0.987, p < 0.001) who had been vaccinated against COVID-19 (anxiety: OR: 0.49, 95% CI: 0.32-0.75, p = 0.001; depression: OR: 0.45, 95% CI: 0.29-0.69, p < 0.001) had decreased incidences of anxiety and depression. Conclusion: Our findings increase the awareness of the high incidence of mental health illness symptoms during the omicron variant outbreak despite previous experiences with the COVID-19 pandemic, and vaccination is suggested to reduce the risk of anxiety and depression.

Omicron COVID-19 variant outcomes and vaccination in non-severe and non-critical patients at admission.

The clinical data of patients infected with the Omicron variant virus in Zhejiang Province from January to 14 May 2022 were collected retrospectively. We analyzed the differences in symptoms, clinical categories of COVID-19, length of hospital stay, and time for clearance of Omicron variant viral RNA in the sputum among the groups receiving a different number of vaccine doses. The analysis showed that as the number of vaccine doses increased, the frequency of clinical symptoms, such as fever and fatigue, decreased and the frequency of patients with moderate infections gradually decreased. At the same time, the length of hospital stay was significantly shortened. Based on the multivariate analysis, one vaccine dose [odds ratio (OR): 0.21, 95% confidence interval (CI): 0.08-0.56, p = 0.002], two vaccine doses (OR: 0.54, 95% CI: 0.33-0.88, p = 0.013), and three vaccine doses (OR: 0.40, 95% CI: 0.24-0.64, p < 0.001) shortened the length of hospitalization than those with no vaccination. The persistence of the virus in the sputum was significantly shortened with one vaccine dose (OR: 0.36, 95% CI: 0.15-0.89, p = 0.027), two vaccine doses (OR: 0.46, 95% CI: 0.27-0.78, p = 0.004), and three vaccine doses (OR: 0.38, 95% CI: 0.22-0.64, p < 0.001) than those with no vaccination. Therefore, we concluded that vaccination was an effective way to protect people against infection with the Omicron variant. Indeed, on the premise of the current routine recommendation of vaccination, three vaccines were necessary for people to be protected against the Omicron variant.

Proton Pump Inhibitor Therapy Does Not Affect Prognosis of Cirrhosis Patients With Acute Decompensation and Acute-on-Chronic Liver Failure: A Single-Center Prospective Study.

Background: The aim of this study was to investigate the impact of proton pump inhibitor (PPI) therapy on complications and prognosis in cirrhosis patients with and without acute-on-chronic liver failure (ACLF). Materials and Methods: Cirrhosis patients with acute decompensation (AD) (n = 489) admitted in our center were enrolled in this prospective observational cohort study. According to treatment received, patients were identified as users or nonusers of PPI. Clinical and laboratory data, complications during hospitalization, and overall survival were recorded in all the patients. Results: Of the 489 patients, 299 (61.1%) patients received PPI therapy. The logistic regression analysis showed that age, albumin, history of previous hepatic encephalopathy (HE), and the chronic liver failure-sequential organ failure assessment (CLIF-SOFA) score were independent risk factors for HE in patients with decompensated cirrhosis [odds ratio (OR) = 1.07, 95% CI: 1.03-1.12, p = 0.001; OR = 1.13, 95% CI: 1.04-1.24, p = 0.006; OR = 242.52, 95% CI: 40.17-1464.11, p < 0.001; and OR = 2.89, 95% CI: 2.11-3.96, p < 0.001, respectively]. Previous severe liver injury and previous bacterial infections were independent risk factors for spontaneous bacterial peritonitis (SBP) in patients with decompensated cirrhosis (OR = 3.43, 95% CI: 1.16-10.17, p = 0.026 and OR = 6.47, 95% CI: 2.29-18.29, p < 0.001, respectively). The multivariate Cox proportional hazards regression model showed that the type and dose of the PPI used were not related to 28-day and 90-day mortality in cirrhosis patients with AD or ACLF. Conclusion: PPI use does not appear to increase mortality or the risk of HE and SBP in the hospitalized cirrhosis patients with and without ACLF.

Discrimintion and Mapping of the Primary and Processed Transcripts in Maize Mitochondrion Using a Circular RT-PCR-based Strategy.

In plant mitochondria, some steady-state transcripts have 5' triphosphate derived from transcription initiation (primary transcripts), while the others contain 5' monophosphate generated post-transcriptionally (processed transcripts). To discriminate between the two types of transcripts, several strategies have been developed, and most of them depend on presence/absence of 5' triphosphate. However, the triphosphate at primary 5' termini is unstable, and it hinders a clear discrimination of the two types of transcripts. To systematically differentiate and map the primary and processed transcripts stably accumulated in maize mitochondrion, we have developed a circular RT-PCR (cRT-PCR)-based strategy by combining cRT-PCR, RNA 5' polyphoshpatase treatment, quantitative RT-PCR (RT-qPCR), and Northern blot. As an improvement, this strategy includes an RNA normalization step to minimize the influence of unstable 5' triphosphate. In this protocol, the enriched mitochondrial RNA is pre-treated by RNA 5' polyphosphatase, which converts 5' triphsophate to monophosphate. After circularization and reverse transcription, the two cDNAs derived from 5' polyphosphatase-treated and non-treated RNAs are normalized by maize 26S mature rRNA, which has a processed 5' end and is insensitive to 5' polyphosphatase. After normalization, the primary and processed transcripts are discriminated by comparing cRT-PCR and RT-qPCR products obtained from the treated and non-treated RNAs. The transcript termini are determined by cloning and sequencing of the cRT-PCR products, and then verified by Northern blot. By using this strategy, most steady-state transcripts in maize mitochondrion have been determined. Due to the complicated transcript pattern of some mitochondrial genes, a few steady-state transcripts were not differentiated and/or mapped, though they were detected in a Northern blot. We are not sure whether this strategy is suitable to discriminate and map the steady-state transcripts in other plant mitochondria or in plastids.
