Resistance to rifampin (rifampicin), isoniazid, and streptomycin of 69 Mycobacterium tuberculosis isolates was analyzed by an in-house method based on mycobacteriophage D29 and a colorimetric micromethod. Both methods showed sensitivity and specificity values ranging from 93% to 100%. These simple methods offer an option for drug resistance assessment of M. tuberculosis.

Research on the application effect of arthroscopic access modification in meniscal injury repair.
J Orthop Surg Res
January 2025
Shengli Clinical Medical College of Fujian Medical University, Fuzhou, 350001, P. R. China.
Objective: To investigate the application value of arthroscopic channel modification in meniscal injury repair.
Methods: We retrospectively analyzed the data of 100 patients with meniscus injuries treated with knee arthroscopy from December 2022 to December 2023 and divided them into a control group and a modified group according to the application of "arthroscopic access modification technology". We compared the operation time, postoperative hospitalization time, VAS score, Lysholm knee function score, postoperative complications, and postoperative images of the patients in these two groups.
Comparison of AI applications and anesthesiologist's anesthesia method choices.
BMC Anesthesiol

BMC Surg
January 2025
Department of Surgery, Shanghai Jiao Tong University Affiliated Sixth People's Hospital, 600 Yishan Road, Shanghai, 200233, China.
Objective: Proximal gastrectomy (PG) is commonly used to remove proximal gastric cancer leading to gastroesophageal reflux and requires digestive tract reconstruction. This study is to compare the performance of esophagogastrostomy (EG), jejunal interposition (JI), and double tract reconstruction (DTR) on post-PG reconstruction effectiveness.
Methods: A retrospective study was conducted using the clinical data of 94 PG patients who underwent digestive tract reconstruction by EG (37 patients), JI (29 patients) or DTR (28 patients).
Background: Population aging and the increase in memory-related diseases have motivated the search for accessible cognitive screening instruments. To develop a digital memory and learning test (DMLT) based on Rey's Auditory Verbal Learning Test (RAVLT) principles to assess cognition in the elderly and identify early cognitive decline.
Methods: The research was divided into two phases: developing the digital test and the experimental phase of comparison with a reference test.
Comparison between AI and human expert performance in acute pain assessment in sheep.
Sci Rep
January 2025
Department of Information Systems, University of Haifa, Haifa, Israel.
This study explores the question whether Artificial Intelligence (AI) can outperform human experts in animal pain recognition using sheep as a case study. It uses a dataset of N = 48 sheep undergoing surgery with video recordings taken before (no pain) and after (pain) surgery. Four veterinary experts used two types of pain scoring scales: the sheep facial expression scale (SFPES) and the Unesp-Botucatu composite behavioral scale (USAPS), which is the 'golden standard' in sheep pain assessment.
