RESUMEN
Purpose@#This study aims to elucidate the longitudinal alterations in frailty and health-related quality of life experienced by elderly patients undergoing surgical treatment for esophageal cancer. Additionally, it seeks to ascertain the impact of preoperative frailty on postoperative health-related quality of life over time. @*Methods@#131 patients were included in the prospective study. Patients' frailty and health-related quality-of-life were assessed utilizing the Tilburg and European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 at preoperative, 1 week, 1 month, and 3 months, postoperatively. Statistical analyses were performed using generalized estimating equations, repeated-measures analysis of variance, and linear mixed models (LMMs). @*Results@#Out of 131 patients, 28.2% had frailty before surgery, and the prevalence of frailty consistently higher after surgery compared with baseline (67.9%, 51.9%, and 39.7%). There was no significant change in frailty scores in preoperative frail patients within 3 months following surgery (p = .496, p < .999, p < .999); whereas in preoperative non-frail patients, the frailty scores increased at 1 week (p < .001) and then decreased at 1 month (p = .014), followed by no change at 3 months. In addition, preoperative frail patients had significantly worse global quality-of-life (β = −4.24 (−8.31; −.18), p = .041), physical functioning (β = −9.87 (−14.59; −5.16), p < .001), role functioning (β = −10.04 (−15.76; −4.33), p = .001), and social functioning (β = −8.58 (−15.49; −1.68), p = .015), compared with non-frail patients. @*Conclusions@#A significant proportion of participants exhibited a high prevalence of preoperative frailty. These patients, who were preoperatively frail, exhibited a marked reduction in health-related quality-of-life, a more gradual recovery across various functional domains, and an increased symptom burden during the follow-up period. Therefore, it is crucial to meticulously identify and closely monitor patients with preoperative frailty for any changes in their postoperative physiology, role, and social functioning.
RESUMEN
Background/Aims@#Intestinal Behçet disease is typically associated with ileocecal punched-out ulcers and significant morbidity and mortality. Intestinal ultrasound is a noninvasive imaging technique for disease monitoring. However, no previous reports have compared intestinal ultrasound with endoscopic ulcer activity or histopathological findings for intestinal Behçet disease. We evaluated the usefulness of intestinal ultrasound for assessing the activity of ileocecal ulcers in intestinal Behçet disease. @*Methods@#We retrospectively compared intestinal ultrasound findings with 73 corresponding endoscopic images and 6 resected specimens. The intestinal ultrasound findings were assessed for 7 parameters (bowel wall thickness, vascularity [evaluated using the modified Limberg score with color Doppler], bowel wall stratification, white-plaque sign [strong hyperechogenic lines or spots], mesenteric lymphadenopathy, extramural phlegmons, and fistulas), and endoscopic ulcer activity was classified into active, healing, and scar stages. Histopathological findings were evaluated by consensus among experienced pathologists. @*Results@#Bowel wall thickness (P 5.5 mm (sensitivity 89.7%, specificity 85.3%) was potentially useful for detecting active lesions. When compared with histopathological findings, an increase in bowel wall thickness reflected the ulcer marginal ridge, and the white-plaque sign reflected the ulcer bottom. @*Conclusions@#Intestinal ultrasound is useful for monitoring intestinal ulcer activity in intestinal Behçet disease.

RESUMEN
Bacterial β-glucuronidases (BGUSs) are an important type of hydrolase produced by gut microbiota and play an important role in tumor development and chemotherapy by deconjugating a large number of endogenous and exogenous glucuronides. In recent years, BGUSs inhibition has emerged as a promising approach to reduce cancer risk and alleviate gastrointestinal toxicity of chemotherapy drugs. However, a growing body of evidence underlines great genetic and structural diversity, functional promiscuity, and varied inhibition propensity of BGUSs, which have posed enormous challenges to identifying BGUSs involved in a specific pathophysiological or pharmacological process and developing effective inhibitors. In this review, we summarize the latest advances in structure and function of BGUSs and review the findings of BGUSs-mediated carcinogen reactivation and deconjugation of chemotherapy drugs in recent years, as well as the discovery of BGUSs inhibitors and preclinical investigation of their applications in cancer prevention and drug therapy. Finally, we discuss the prospects of BGUSs inhibition as a new strategy for tumor prevention and drug therapy.

RESUMEN
Objective To observe the influence of intravenous anesthesia with ketamine or propofol on intraocular pressure (IOP) in pediatric patients. Methods 27 pediatric patients, ASA grade Ⅰ～Ⅱ, were divided into ketamine and propofol groups. Basic anesthesia was conducted with ketamine 4～6 mg*kg-1 combined droperidol 0.04～0.1 mg*kg-1 intramuscularly. Anesthesia maintained with continous infusion of 0.04% ketamine or 0.04% propofol following intravenous bolus of ketamine 1 mg*kg-1 or propofol 1 mg*kg-1 in ketamine group and propofol group respectively. IOP, systemic blood pressure(SBP), diastolic blood pressure(DBP), heart rate(HR) and pulse oxygen saturation(SpO2) were measured at 10 minutes after basic anesthesia, 3 minutes after intravenous bolus of ketamine or propofol and end of surgery. Results There were no differences in IOP between two groups after basic anesthesia. IOP increased or decreased significantly after intravenous bolus of ketamine or propofol respectively. IOP in ketamine group decreased near to the level in propofol group at end of surgery. There were no statistic differences in SBP, DBP and HR between two groups priopration. SpO2 did not change (but in one patient decreasing to below 95% ) and significantly decreased within 5 minutes of intravenous bolus of ketamine and propofol respectively. Conclusion Ketamine increases IOP propofol decreases IOP. Ketamine combined propofol can keep from increase of IOP but strength respiration inhibition.
RESUMEN
<p><b>OBJECTIVE</b>To examine the prevalence and the sequence of the genes of new genotypes of hepatitis G virus (HGV) in Guangxi, China.</p><p><b>METHODS</b>Serum samples were collected from 85 intravenous drug abusers (IVDAs), 80 patients with liver diseases (PLDs) and 50 blood donors (BDs). All sera (n=215) were tested by using EIA for HBsAg, anti-HCV and anti-HIV, and by using nested PCR for HGV RNA. In 62 subjects positive for HGV, HGV RNA was sequenced, and a phylogenetic tree was constructed for analyzing genotypes of HGV.</p><p><b>RESULTS</b>HGV RNA was detected in 85 of 215 serum samples (39.53%). The positivity rates for HBsAg, anti-HCV and anti-HIV were 39.07%, 42.79% and 0, respectively. First, 11 nucleotide sequences were determined and the isolates were grouped into three clusters with HGV. 5 of 11 HGV isolates clustered in a distinct phylogenetic branch (genotype Asia) which was different from the described GBV-C and HGV sequences, suggesting the presence of a new genotype of HGV in this locality. Second, 51 nucleotide sequences were determined and analyzed for their genotypes of HGV, and showed genotype GBV-C (3.23%), genotype HGV 30-65% and new genotype (genotype Asia) 64.51%, respectively.</p><p><b>CONCLUSIONS</b>There were subgenotypes in 3 genotypes of HGV; The predominant genotypes of HGV were genotype Asia and genotype HGV among IVDAs, PLDs, and BDs patients in Guangxi, China.</p>
