Predicting 1-year non-cancer-related adverse events after lung resection.
Interdiscip Cardiovasc Thorac Surg
December 2023
Article Synopsis
- The study focuses on assessing non-cancer-related complications after lung cancer surgery, specifically looking at the impact of lung volume resection and postoperative atrial fibrillation (POAF) within one year of surgery.!* -
- A retrospective analysis of 460 patients found that 20% experienced non-cancer-related adverse events, with factors like age, lung function, number of resected subsegments, and POAF being significant predictors.!* -
- Findings suggest that minimizing lung volume resection and identifying patients at risk for POAF can enhance postoperative outcomes, providing valuable insights for preoperative planning in lung cancer surgery.!*
Objective This study analyzed changes in the estimated glomerular filtration rate calculated using cystatin C (eGFRcys) and sodium excretion in the urine after administering dapagliflozin as an add-on therapy to conventional treatment for diabetes. Methods This was a single-center, single-group, prospective interventional study. Dapagliflozin was administered to improve the plasma glucose control in 30 subjects with type 2 diabetes mellitus (age 53±8 years old; 66.

We present a case of a 60-year-old woman who was diagnosed with a gastric glomus tumor using endoscopic ultrasonography-guided fine-needle aspiration biopsy. The tumor was successfully resected with laparoscopic endoscopic cooperative surgery (LECS).

Methods: Overall, 312 patients with postoperative ASBO were included.
Article Synopsis
- The study aims to compare the effectiveness and safety of laparoscopic versus open surgery for adhesive small bowel obstruction (ASBO) based on data from 42 Japanese university hospitals.
- The analysis involved matching 96 patients who underwent laparoscopic surgery with 96 who had open surgery, evaluating outcomes like morbidity, mortality, hospital stay length, and recurrence rates.
- Results showed that while there were no significant differences in overall complications between the two methods, laparoscopic surgery resulted in a shorter hospital stay (10 days vs. 13 days) and allowed for earlier discharge than open surgery.
Article Synopsis
- Acute mesenteric ischemia, a serious complication after cardiovascular surgery, has a very high mortality rate, but its predictors post-treatment are not well studied.
- This research analyzed 29 patients who had laparotomy for this condition after cardiovascular procedures, classifying them into survivor and nonsurvivor groups to identify clinical outcome predictors.
- Findings indicated that higher serum creatinine levels before surgery were significantly associated with in-hospital mortality, suggesting that this lab value could be an important predictor for patient outcomes.
Background: Neurofibromatosis type 1 is an autosomal dominant inherited disease associated with multiple skin neurofibromas or other neurogenic tumors, such as nodular plexiform neurinoma or cerebrospinal tumor. Gastrointestinal stromal tumors are often complicated in patients with neurofibromatosis type 1, although involvement of the appendix is rare, and there have been few reports of appendiceal ganglioneuroma.
Case Presentation: The patient was a 29-year-old man diagnosed with neurofibromatosis type 1 based on physical findings and his family history.
A new method for preparing plan-view TEM specimen of multilayered films using focused ion beam.
J Electron Microsc (Tokyo)
March 2005
A new method is proposed for preparing plan-view specimens of a CeO(2)/Gd(2)Zr(2)O(7) multilayer on a metal substrate using focused ion beam milling. In the plan-view specimen, a membrane from the surface region of the CeO(2) to the Gd(2)Zr(2)O(7) layer was thinned to electron transparence so that the entire span of the multilayer can be observed in a single sample. The in-plane alignments of the CeO(2) layer and the Gd(2)Zr(2)O(7) layer were analysed using selected-area diffraction patterns (SADPs).

A micrometresized specimen was mounted on a cross section of metal foil of a few micrometres thick, using FIB microsampling. Following this, a 2 degrees wedgeshaped part was made in the specimen using FIB.
