Background: In recent trend of preoperative chemotherapy, postoperative clostridium difficile infection (CDI) might be increasing in pancreatic ductal adenocarcinoma (PDAC) patients. This study aimed to elucidate the inducement of postoperative CDI in the new era of preoperative chemotherapy.
Methods: Eligible patients were those who received pancreaticoduodenectomy for PDAC. Patients were classified into two groups according to the presence or absence of postoperative CDI, and the independently associated factors for postoperative CDI were investigated. Additionally, eligible patients were classified using the identified associated factors, and the duration of preoperative antimicrobial administration and incidence of CDI were compared between the groups.
Results: Two hundred PDAC patients were eligible for this study, and postoperative CDI was detected in 15 (7.5%) patients. Multivariate analysis revealed that preoperative biliary tract infection (BTI) and chemotherapy (Chemo) were independently associated with postoperative CDI (OR, 4.05; 95% CI, 1.25-13.1; p = 0.0200 and OR, 3.64; 95% CI, 1.14-11.6; p = 0.0209, respectively). The patients were classified into four groups according to the presence or absence of preoperative BTI and Chemo (BTI-/Chemo-, BTI-/Chemo+, BTI+/Chemo- and BTI+/Chemo + group). The median durations of preoperative antimicrobial administration were 0, 2, 8 and 15 days in each group, respectively. Postoperative CDI was detected in 3.7%, 10.0%, 10.5% and 31.3% in each group, respectively, and patients in BTI+/Chemo + group suffered CDI more frequently compared to those in BTI-/Chemo-group (p = 0.00778).
Conclusions: Preoperative BTI and chemotherapy might induce postoperative CDI for PDAC patients.

: Glaucomatous neuropathy, a progressive deterioration of retinal ganglion cells, is the leading cause of irreversible blindness worldwide. While elevated intraocular pressure (IOP) is a well-established modifiable risk factor, increasing attention is being directed towards IOP-independent factors, such as vascular alterations. Color Doppler imaging (CDI) is a prominent technique for investigating blood flow parameters in extraocular vessels.

Background: Tibial condylar valgus osteotomy (TCVO), or Chiba osteotomy, is a recognized procedure for treating advanced knee osteoarthritis in middle-aged individuals. Although its effectiveness is established, limited literature exists on its outcomes for specific conditions such as post-traumatic deformities, Blount disease (BD), and Pagoda-like proximal tibia varus deformities.
Hypothesis: We hypothesized that TCVO could improve both clinical and radiographic outcomes in patients with severe varus deformities, correcting lower-limb variances while preserving joint line obliquity (JLO) and patellar height in substantial varus deformities.

Article Synopsis
- - The study focuses on melanoma treatment challenges, highlighting the need for a model that can predict prognosis and assess drug sensitivity using programmed cell death (PCD) modes.
- - Researchers analyzed 13 PCD modes to create a Cell Death Index (CDI) based on gene signatures, which was validated with various data sources and showed distinct differences in patient outcomes.
- - The CDI model effectively predicts melanoma prognosis and drug resistance, indicating that patients with higher CDI values have poorer postoperative outcomes.

Objective: To evaluate postoperative outcomes among patients undergoing colon surgery who receive perioperative prophylaxis with ertapenem compared to other antibiotic regimens.
Design And Setting: Multicenter retrospective cohort study among adults undergoing colon surgery in seven hospitals across three health systems from 1/1/2010 to 9/1/2015.
Methods: Generalized linear mixed logistic regression models were applied to assess differential odds of select outcomes among patients who received perioperative prophylaxis with ertapenem compared to other regimens.

Article Synopsis
- CDI (Clostridioides difficile infection) is a significant post-operative complication with a poor prognosis and no standardized treatment, often caused by various factors affecting the gut environment.
- A patient with a long history of bowel obstruction underwent surgery for colon issues but developed CDI shortly after, leading to a successful initial treatment, but unfortunately, the patient did not continue medication and later died.
- The case emphasizes the importance of addressing potential CDI risks in patients with chronic bowel conditions and the necessity of consistent medication to prevent recurrence after treatment.
