Purpose: Colorectal cancer (CRC) often spreads to the liver, necessitating surgical treatment for CRC liver metastasis (CRLM). Iron-deficiency anemia is common in CRC patients and is associated with fatigue and weakness. This study investigated the effects of iron-deficiency anemia on the outcomes of surgical resection of CRLM. Methods: This population-based, retrospective study evaluated data from adults ≥20 years old with CRLM who underwent hepatic resection. All patient data were extracted from the 2005–2018 US National (Nationwide) Inpatient Sample (NIS) database. The outcome measures were in-hospital outcomes including 30-day mortality, unfavorable discharge, and prolonged length of hospital stay (LOS), and short-term complications such as bleeding and infection. Associations between iron-deficiency anemia and outcomes were determined using logistic regression analysis. Results: Data from 7,749 patients (representing 37,923 persons in the United States after weighting) were analyzed. Multivariable analysis revealed that iron-deficiency anemia was significantly associated with an increased risk of prolonged LOS (adjusted odds ratio [aOR], 2.76; 95% confidence interval [CI], 2.30–3.30), unfavorable discharge (aOR, 2.42; 95% CI, 1.83–3.19), bleeding (aOR, 5.05; 95% CI, 2.92–8.74), sepsis (aOR, 1.60; 95% CI, 1.04–2.46), pneumonia (aOR, 2.54; 95% CI, 1.72–3.74), and acute kidney injury (aOR, 1.71; 95% CI, 1.24–2.35). Subgroup analyses revealed consistent associations between iron-deficiency anemia and prolonged LOS across age, sex, and obesity status categories. Conclusion In patients undergoing hepatic resection for CRLM, iron-deficiency anemia is an independent risk factor for prolonged LOS, unfavorable discharge, and several critical postoperative complications. These findings underscore the need for proactive anemia management to optimize surgical outcomes.

Purpose: This study was conducted to evaluate the efficacy of bladder outlet surgery in patients with detrusor underactivity (DU) and to identify factors associated with successful outcomes. Methods: We conducted a retrospective review of men diagnosed with DU in urodynamic studies who underwent bladder outlet surgery for lower urinary tract symptoms between May 2018 and April 2023. The International Prostate Symptom Score (IPSS) questionnaire, uroflowmetry (UFM), and multichannel urodynamic studies were administered. Successful treatment outcomes were defined as either an IPSS improvement of at least 50% or the regaining of spontaneous voiding in patients urethral catheterization prior to surgery. Results: The study included 93 male patients. Men diagnosed with significant or equivocal bladder outlet obstruction (BOO) experienced significant postoperative improvements in IPSS (from 20.6 to 6.0 and from 17.4 to 6.5, respectively), maximum urine flow rate (from 5.0 mL/sec to 14.4 mL/sec and from 8.8 mL/sec to 12.2 mL/sec, respectively) and voiding efficiency (from 48.8% to 86.0% and from 61.2% to 85.1%, respectively). However, in the group without obstruction, the improvements in IPSS and UFM results were not significant. The presence of detrusor overactivity (odds ratio [OR], 3.152; P=0.025) and preoperative urinary catheterization (OR, 2.756; P=0.040) were associated with favorable treatment outcomes. Conversely, an unobstructed bladder outlet was identified as a negative prognostic factor. Conclusions In men with DU accompanied by equivocal or significant BOO, surgical intervention to alleviate the obstruction may enhance the IPSS, quality of life, and UFM results. However, those with DU and an unobstructed bladder outlet face a comparatively high risk of treatment failure. Preoperative detrusor overactivity and urinary catheterization are associated with more favorable surgical outcomes. Consequently, active deobstructive surgery should be considered for patients with DU who are experiencing urinary retention.

This study reports the outcomes of a collaborative program between dialysis clinics and a referral hospital, which consisted of clinical monitoring and supplementary routine surveillance, for improving the quality of vascular access care. Methods: This retrospective observational study was performed at five dialysis clinics as part of a 2-year collaborative program (2019–2020) in conjunction with a hospital-based dialysis access management center. A total of 392 hemodialysis patients (arteriovenous fistula [AVF], n = 339 and arteriovenous graft [AVG], n = 53) were included. Outcome measures included the prognosis of vascular access, clinic satisfaction, and referral rate to the hospital. Results: Increased vascular access flow was observed and critical flow events decreased from the first to the second year (AVF: 18.3% vs. 12.7%, p < 0.001; AVG: 26.2% vs. 20.1%, p = 0.30). There were fewer percutaneous transluminal angioplasty events in the AVG group (0.77 per person-year vs. 0.51 per person-year, p = 0.005). New AVF or AVG creation events also remained low. All dialysis clinics were satisfied with the program. The overall referral rate from the participating clinics increased (65.7% vs. 72.0%) during the study period independently of the physical distance between the dialysis clinic and the hospital. Conclusion: The collaboration between dialysis clinics and a referral hospital for improving the quality of vascular access care was successful in this study, and the model can be used by other clinics and hospitals looking to improve care coordination in dialysis patients.

Objective:To investigate the safety and short-term efficacy of laparoscopic pro-ximal gastrectomy (LPG) for proximal gastric cancer and adenocarcinoma of esophagogastric junction.Methods:The retrospective cohort study was conducted. The clinicopathological data of 385 patients with proximal gastric cancer and adenocarcinoma of esophagogastric junction who underwent LPG in the 15 medical centers, including the First Affiliated Hospital of Xiamen University et al, from January 2014 to March 2022 were collected. There were 304 males and 81 females, aged (63±9)years. Of the 385 patients, 335 cases undergoing LPG were divided into the laparoscopic group and 50 cases undergoing open proximal gastrectomy were divided into the open group. Observation indicators: (1) intraoperative and postoperative situations; (2) follow-up; (3) stratified analysis. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the t test. Measurement data with skewed distribution were represented as M(range), and comparison between groups was conducted using the Wilcoxon rank sum test. Count data were described as absolute numbers, and comparison between groups was conducted using the chi-square test or Fisher exact probability. Repeated measurement data were analyzed using the repeated ANOVA. Results:(1) Intraoperative and postoperative situations. The operation time, cases with reconstruction of digestive tract as esophagogastric anastomosis and esophageal-jejunal anastomosis, cases with postoperative pathological staging as stage 0?Ⅰ and stage Ⅱ?Ⅲ, duration of postoperative hospital stay, cases with postoperative early complications were (212±96)minutes, 270, 65, 177, 107, 10(range, 8?14)days, 40 in patients of the laparoscopic group, with 51 cases missing the data of postoperative pathological staging. The above indicators were (174±90)minutes, 39, 11, 22, 28, 10(range, 8?18)days, 10 in patients of the open group. There were significant differences in the opera-tion time and postoperative pathological staging between the two groups ( t=2.62, χ2=5.93, P<0.05), and there was no significant difference in the reconstruction of digestive tract, duration of post-operative hospital stay, postoperative early complications between the two groups ( χ2=0.19, Z=0.40, χ2=2.50, P>0.05). (2) Follow-up. Of the 385 patients,202 cases were followed up during the post-operative 12 months, including 187 cases in the laparoscopic group and 15 cases in the open group. Cases with reflux esophagitis, cases with esophageal anastomotic stenosis were 48, 11 in patients of the laparoscopic group, versus 5, 2 in patients of the open group, showing no significant difference in the above indicators between the two groups ( P>0.05). The body mass index (BMI), hemoglobin (Hb), albumin (Alb) at postoperative 6 months and 12 months were (21±3)kg/m 2, (130±15)g/L, (40±4)g/L and (21±3)kg/m 2, (132±14)g/L, (41±4)g/L in patients of the laparoscopic group, versus (21±3)kg/m 2, (121±19)g/L, (37±5)g/L and (21±3)kg/m 2, (125±21)g/L, (43±6)g/L in patients of the open group. There were significant differences in postoperative Hb between the two groups ( Fgroup=5.88, Ftime=5.49, Finteraction=19.95, P<0.05) and there were significant differences in time effect of postopera-tive BMI and Alb between the two groups ( Ftime=9.53, 49.88, P<0.05). (3) Stratified analysis. ① Incidence of postoperative of reflux esophagitis and esophageal anastomotic stenosis in patients with different reconstruction of digestive tract. Of the 202 patients, cases with reconstruction of digestive tract as esophagogastric anastomosis and esophageal-jejunal anastomosis were 168 and 34, respectively. The incidence rates of postoperative of reflux esophagitis were 26.79%(45/168)and 23.53%(8/34)in cases with reconstruction of digestive tract as esophagogastric anastomosis and esophageal-jejunal anastomosis, showing no significant difference between them ( χ2=0.16, P>0.05). Cases undergoing esophageal anastomotic stenosis were 13 in patients with reconstruction of diges-tive tract as esophagogastric anastomosis. ② The BMI, Hb, Alb in patients with different reconstruc-tion of digestive tract. The BMI, Hb, Alb were (24±3)kg/m 2, (135±20)g/L, (41±5)g/L in the 168 patients with reconstruction of digestive tract as esophagogastric anastomosis before the operation, versus (23±3)kg/m 2, (130±19)g/L, (40±4)g/L in the 34 patients with reconstruction of digestive tract as esophageal-jejunal anastomosis before the operation, showing no significant difference between them ( t=1.44, 1.77, 1.33, P>0.05). The BMI, Hb, Alb at postoperative 6 months and 12 months were (21±3)kg/m 2, (128±16)g/L, (39±4)g/L and (21±3)kg/m 2, (131±16)g/L, (41±4)g/L in the 168 patients with reconstruction of digestive tract as esophagogastric anastomosis, versus (20±4)kg/m 2, (133±13)g/L, (43±3)g/L and (21±3)kg/m 2, (135±12)g/L, (44±3)g/L in the 34 patients with reconstruction of digestive tract as esophageal-jejunal anastomosis. There were significant differences in the group effect and time effect of postoperative Alb between patients with different reconstruction of diges-tive tract ( Fgroup=15.82, Ftime=5.43, P<0.05), and there was also a significant difference in the time effect of postoperative BMI between them ( Ftime=4.22 , P<0.05). Conclusion:LPG can be used to the treatment of proximal gastric cancer and adenocarcinoma of esophagogastric junction, with a good safety and short-term efficacy.

Background: To compare risk of diabetic retinopathy (DR) between patients taking sodium-glucose cotransporter-2 inhibitors (SGLT2is) and those taking glucagon-like peptide-1 receptor agonists (GLP1-RAs) in routine care. Methods: This retrospective cohort study emulating a target trial included patient data from the multi-institutional Chang Gung Research Database in Taiwan. Totally, 33,021 patients with type 2 diabetes mellitus using SGLT2is and GLP1-RAs between 2016 and 2019 were identified. 3,249 patients were excluded due to missing demographics, age <40 years, prior use of any study drug, a diagnosis of retinal disorders, a history of receiving vitreoretinal procedure, no baseline glycosylated hemoglobin, or no follow-up data. Baseline characteristics were balanced using inverse probability of treatment weighting with propensity scores. DR diagnoses and vitreoretinal interventions served as the primary outcomes. Occurrence of proliferative DR and DR receiving vitreoretinal interventions were regarded as vision-threatening DR. Results: There were 21,491 SGLT2i and 1,887 GLP1-RA users included for the analysis. Patients receiving SGLT2is and GLP-1 RAs exhibited comparable rate of any DR (subdistribution hazard ratio [SHR], 0.90; 95% confidence interval [CI], 0.79 to 1.03), whereas the rate of proliferative DR (SHR, 0.53; 95% CI, 0.42 to 0.68) was significantly lower in the SGLT2i group. Also, SGLT2i users showed significantly reduced risk of composite surgical outcome (SHR, 0.58; 95% CI, 0.48 to 0.70). Conclusion Compared to those taking GLP1-RAs, patients receiving SGLT2is had a lower risk of proliferative DR and vitreoretinal interventions, although the rate of any DR was comparable between the SGLT2i and GLP1-RA groups. Thus, SGLT2is may be associated with a lower risk of vision-threatening DR but not DR development.

Purpose: This study aimed to compare the ability of B-mode ultrasonography and magnetic resonance imaging (MRI) to predict the repairability of large-to-massive rotator cuff tears (RCTs). Methods: This cross-sectional study included participants with large-to-massive RCTs who underwent arthroscopic repair. B-mode ultrasonography and MRI were conducted prior to arthroscopic repair. B-mode ultrasonography was used to evaluate the echogenicity of the rotator cuff muscle using the Heckmatt scale. Intra-rater and inter-rater reliabilities were examined for two independent physicians. MRI was used to evaluate the degrees of tendon retraction, fatty infiltration of rotator cuff muscles, and muscle atrophy. Finally, two experienced orthopedic surgeons performed surgery and decided whether the torn stump could be completely repaired intraoperatively. Results: Fifty participants were included, and 32 complete repairs and 18 partial repairs were performed. B-mode ultrasonography showed good intra-rater reliability and inter-rater reliability for assessment of the muscle echogenicity of the supraspinatus and infraspinatus muscles. The correlation coefficients between B-mode ultrasound findings and MRI findings showed medium to large effect sizes (r=0.4-0.8). The Goutallier classification of the infraspinatus muscles was the MRI predictor with the best discriminative power for surgical reparability (area under the curve [AUC], 0.89; 95% confidence interval [CI], 0.81 to 0.98), while the Heckmatt scale for infraspinatus muscles was the most accurate ultrasound predictor (AUC, 0.85; 95% CI, 0.74 to 0.96). No significant differences in AUCs among the MRI and ultrasound predictors were found. Conclusion B-mode ultrasonography was a reliable examination tool and had a similar ability to predict surgical reparability to that of MRI among patients with large-to-massive RCTs.
