Background: For the initial treatment strategy for patients with cardiac resynchronization therapy (CRT) indications, whether to choose left bundle branch area pacing (LBBaP) or biventricular pacing (BVP) remains controversial. We aimed to investigate the cost-effectiveness ratio (CER) of LBBaP and BVP in heart failure (HF) patients with left bundle branch block (LBBB).

Methods: This observational study included HF patients with LBBB who underwent successful LBBaP or BVP.

Background: Left bundle branch area pacing (LBBAP) demonstrated beneficial effects on clinical outcomes. Comparative data on the risk of atrial high-rate episodes (AHREs) between LBBAP and right ventricular pacing (RVP) are lacking.

Aims: This study aimed to investigate whether LBBAP can reduce the risk of new-onset AHREs compared with RVP in patients with atrioventricular block (AVB).

Domain adaptation leverages labeled data from a source domain to learn an accurate classifier for an unlabeled target domain. Since the data collected in practical applications usually contain noise, the weakly-supervised domain adaptation algorithm has attracted widespread attention from researchers that tolerates the source domain with label noises or/and features noises. Several weakly-supervised domain adaptation methods have been proposed to mitigate the difficulty of obtaining the high-quality source domains that are highly related to the target domain.

To evaluate the clinical efficacy of pelvic floor low-frequency electrical stimulation combined with anus lifting training in the treatment of urinary incontinence after radical prostatectomy in a Chinese cohort. Fifty-five patients with urinary incontinence after radical prostatectomy were randomly divided into treatment group and control group. Patients in control group received only anus lifting training therapy, while treatment group combined with pelvic floor low-frequency electrical stimulation.

Article Synopsis
  • The study investigated the occurrence and factors related to T-wave inversions (TWIs) during left bundle branch area pacing (LBBAP), finding that 66.3% of patients experienced TWIs.
  • A longer baseline QRS duration (QRSd >120 ms) was identified as a predictor for TWIs, with 87.8% of patients recovering from TWIs during follow-up.
  • The occurrence of TWIs was linked to specific leads in patients with different types of bundle branch block; however, troponin T levels showed no significant differences between groups.

Left bundle branch block (LBBB) is common in heart failure patients, and could induce dyssynchrony of ventricular contraction, deterioration of cardiac function, and increased mortality. Cardiac resynchronization therapy (CRT) with biventricular pacing reduces ventricular dyssynchrony, heart failure hospitalization, and all-cause mortality in heart failure patients with LBBB. However, there are approximately 30% nonresponders and 10% of patients remain untreated owing to an unsuitable coronary sinus vein.

Background: Transurethral split of the prostate (TUSP) is effective in treating benign prostatic hyperplasia (BPH). However, there is still a lack of research focusing on the optimal target population for TUSP. This study aimed to compare the efficacy of TUSP in patients with different prostate volumes or ages.

Objectives: To describe the influence of the socioeconomic development on worldwide age-standardized incidence and mortality rates, as well as mortality-to-incidence ratio (MIR) and 5-year net survival of urologic cancer patients in recent years.

Methods: The Human Development Index (HDI) values were obtained from the United Nations Development Programme, data on age-standardized incidence/mortality rates of prostate, bladder and kidney cancer were retrieved from the GLOBOCAN database, 5-year net survival was provided by the CONCORD-3 program. We then evaluated the association between incidence/MIR/survival and HDI, with a focus on geographic variability as well as temporal patterns during the last 6 years.

Background: Left bundle branch pacing (LBBP) can produce near normalization of QRS duration. This has recently emerged as alternative technique to right ventricular pacing and His bundle pacing.

Hypothesis: The purpose of this study is to evaluate clinical outcomes of LBBP compared to right ventricular apical pacing (RVAP).

Background And Objective: The aim of this study was to investigate the value of programmed death ligand 1 (PD-L1) expression as a predictive biomarker for Miller/Payne grading before neoadjuvant chemotherapy (NACT) in breast cancer.

Patients And Methods: The expression of PD-L1 in pretreatment biopsies of breast cancer was assessed by immunohistochemistry in tissue microarrays. The results were analyzed using SPSS 22.

Background: Transurethral resection of the prostate (TURP) was considered the golden standard to treat benign prostatic hyperplasia (BPH) for decades. However, TURP was associated with low efficiency to alleviate the lower urinary tract symptoms (LUTS) and a significantly higher risk of bladder neck contracture (BNC) for patients with small-volume BPH. Our study aims to compare the therapeutic effect of a transurethral split of the prostate (TUSP) with TURP for patients with small-volume BPH (<30 mL).

In the era of intensity-modulated radiotherapy (IMRT), it is important to analyse the prognostic value of deficient mismatch repair (dMMR) in nasopharyngeal carcinoma (NPC). In this study, in pretreatment biopsies of 69 patients with stage II-IVa NPC, the expression levels of MMR proteins, including MLH1, MSH2, MSH6 and PMS2, were assessed by immunohistochemistry (IHC). The median follow-up time was 37.

Purpose: To explore the efficacy and safety of flexible ureteroscopic incision and drainage and flexible ureteroscopic lithotripsy for treatment of parapelvic renal cyst combined with secondary renal stone.

Materials And Methods: 28 patients with parapelvic renal cyst combined with renal stone were treated with flexible ureteroscopic incision and drainage and flexible ureteroscopic lithotripsy simultaneously from May 2010 to December 2016.

Prostate cancer (PCa) is one of the major malignancies affecting males' health around the world. Long noncoding RNAs (lncRNAs), a class of long transcripts, has been reported as essential regulators in tumorigenesis. IDH1 antisense RNA 1 (IDH1-AS1) is an lncRNA which can interact with genes to regulate the Warburg effect.
