This study aimed to investigate the prognostic value of the preoperative neutrophil to lymphocyte ratio (NLR) in resectable gastric cancer (GC). This was a retrospective review of 1030 patients with resectable GC managed between 2005 and 2011. Patients were stratified into 2 groups, those with a preoperative NLR >3.44 and those with a preoperative NLR ≤ 3.44. Clinicopathological data affecting patient prognosis were collected prospectively and analyzed. The high NLR (> 3.44) group had a higher proportion of a platelet to lymphocyte ratio > 132, tumor size > 4.8 cm, T4 lesions, metastatic tumors, a ratio of metastatic to examined lymph nodes >0.18, positive resection margins, and presence of vascular or lymphatic invasion than the low NLR (≤ 3.44) group. Patients with a high preoperative NLR had significantly lower 3- and 5-year overall survival rates than those with a low preoperative NLR (55.1% vs 71.0% and 47.2% vs 64.1%, respectively; P < 0.001). Preoperative NLR was a prognostic factor for resectable GC in multivariate analysis. More aggressive tumor behavior was observed in patients with resectable GC with a high preoperative NLR than in those with a low preoperative NLR. High preoperative NLR was an independent unfavorable prognostic factor. Measurement of this ratio may serve as a clinically accessible and useful biomarker for patient outcomes.

Cytomegalovirus (CMV) colitis typically presents in immunocompromised and inflammatory bowel disease (IBD) patients. Several studies have been conducted on the endoscopic characteristics of CMV colitis in IBD patients.

There is no current standard rescue treatment for dual drug-resistant strains of Helicobacter pylori (H. pylori). This aim of this study was to investigate the efficacy of rifabutin-based triple therapy for patients infected with dual drug-resistant strains to clarithromycin and levofloxacin.

To comprehensively analyze the risk factors, clinical characteristics, outcomes, and prognostic factors of Cytomegalovirus (CMV) enteritis.

Hepatocellular carcinoma (HCC) is an aggressive solid tumor. HCC occurred at younger and elder ages were considered driven by different oncogenic mechanisms, and they demonstrated distinct clinical courses.

Vancomycin-resistant Clostridium innocuum was recently identified as an etiologic agent for antibiotic-associated diarrhea in humans. We conducted a case-control study involving 152 C. innocuum-infected patients during 2014-2019 in Taiwan, using 304 cases of Clostridioides difficile infection (CDI) matched by diagnosis year, age (+2 years), and sex as controls. The baseline characteristics were similar between the 2 groups. C. innocuum-infected patients experienced more extraintestinal clostridial infection and gastrointestinal tract-related complications than did patients with CDI. The 30-day mortality rate among C. innocuum-infected patients was 14.5%, and the overall rate was 23.0%. Chronic kidney disease, solid tumor, intensive care unit admission, and shock status were 4 independent risk factors for death. C. innocuum identified from clinical specimens should be recognized as a pathogen requiring treatment, and because of its intrinsic vancomycin resistance, precise identification is necessary to guide appropriate and timely antimicrobial therapy.

The positive expression of human epidermal growth factor receptor 2 (HER-2) is phenotypically associated with differentiated gastric cancer (GC) and is a prognostic factor for resectable GC. The aim of this study was to explore the clinical significance of vascular endothelial growth factor (VEGF), protein kinase B, and p38 mitogen-activated protein kinase (MAPK) regarding outcome in patients with HER-2 positive GC, and to analyze the relationship between these molecules and clinicopathologic parameters.

Despite melatonin treatment diminishes inflammatory mediator production and improves organ injury after acute pancreatitis (AP), the mechanisms remain unknown. This study explores whether melatonin improves liver damage after AP through protein kinase B (Akt)-dependent peroxisome proliferator activated receptor (PPAR)-γ pathway.

Hepatitis C virus (HCV) infection causes many extrahepatic malignancies; whether it increases gastric cancer risk and the risk reverses after anti-HCV therapy remain elusive.

Fecal microbiota transplantation (FMT) has been shown to highly effective in the treatment of recurrent or refractory Clostridioides difficile infection (rCDI) in many countries of the world. Not until 2018, Ministry of Health and Welfare, Taiwan approved the application of FMT for rCDI under a special law. The study reported the first implementation of the technology in the medical center in Taiwan and the preliminary outcome.

The role of adjuvant chemotherapy in pathological T3N0M0 (pT3N0M0) gastric cancer (GC) remains unclear. The aim of this study was to analyze the prognostic factors of patients with pT3N0M0 GC and to clarify which ones could benefit from adjuvant chemotherapy. A total of 137 patients with pT3N0M0 GC were recruited between 1994 and 2020. Clinicopathological factors and adjuvant chemotherapy regimens were retrospectively collected. Prognostic factors of disease-free survival (DFS) and cancer-specific survival (CSS) were determined using univariate and multivariate analyses. The chemotherapy group was younger (p = 0.012), had had more lymph nodes retrieved (p = 0.042) and had higher percentages of vascular invasion (p = 0.021) or perineural invasion (p = 0.030) than the non-chemotherapy group. There were no significant differences in DFS (p = 0.222) and CSS (p = 0.126) between patients treated with or without adjuvant chemotherapy. Stump cancer, tumor size and perineural invasion were associated with higher rates of recurrence. Tumor size was an independent prognostic factor for DFS (hazard ratio, 4.55; confidence interval, 1.59-12.99; p = 0.005) and CSS (hazard ratio, 3.97; confidence interval, 1.38-11.43; p = 0.011). Tumor size independently influenced survival outcomes in pT3N0M0 patients who underwent radical surgery with and without adjuvant chemotherapy.
