Objective: To explore the lipid peroxidation and the testicular morphological change induced by decabrominated diphenyl ether (BDE-209) in male BALB/c mice.
Methods: Twenty one male BALB/c mice were randomly divided into three groups: the high exposure group (500 mg/kg BDE-209), the low exposure group (200 mg/kg BDE-20) and control group (normal saline). The mice were exposed by gavage one time a day for 6 weeks, then were sacrificed. Body weight, testis weight, malonyldialdehyde (MDA), total superoxide dismutase (T-SOD) and glutathione (GSH) in testis were examined. The morphological alteration of testis was observed. TUNEL assay was used to detect the apoptosis in testicular cells.
Results: Body weight and testis weight in high and low exposure groups were (21.6140 +/- 2.3550) g, (20.8000 +/- 1.7630) g and (0.1859 +/- 0.0349) g, (0.1718 +/- 0.0266) g, respectively, which were significantly lower than those (27.7570 +/- 1.2880) g and (0.2302 +/- 0.0335) g in the control group (P < 0.05); the testis coefficient in high exposure group was (0.8640% +/- 0.1706%), which was significantly higher than that (0.8329 +/- 0.1386%) in the control group (P < 0.05). The GSH level and SOD activities of testis in 2 BDE-209 groups were 0.044 +/- 0.006, 0.039 +/- 0.005 nmol/mg prot, and 0.735 +/- 0.179, 0.907 +/- 0.198 U/mg prot, respectively, which were significantly lower than those (0.052 +/- 0.067) mol/mg and (1.161 +/- 0.188) U/mg in the control group (P < 0.05). The levels of MDA in 2 BDE-209 groups were (2.365 +/- 0.339) and (1.752 +/- 0.366) nmol/mg prot, which were significantly higher than that (1.173 +/- 0.232 nmol/mg prot) in control group (P < 0.05). there were significant differences of SOD and MDA levels between high exposure group and low exposure group (P < 0.05). Histological examination showed that the number of spermatogenic cells and layer were decreased significantly in 2 exposure groups as compared with control group. TUNEL assay showed that apoptosis cells appeared in 2 exposure groups.
Conclusion: BDE-209 changed lipid peroxidation in male BALB/c mice testis and caused toxic effects on the testis.

Genes encoding OXA-48-like carbapenem-hydrolyzing enzymes are often located on plasmids and are abundant among carbapenemase-producing (CPE) worldwide. After a large plasmid-mediated outbreak in 2011, routine screening of patients at risk of CPE carriage on admission and every 7 days during hospitalization was implemented in a large hospital in the Netherlands. The objective of this study was to investigate the dynamics of the hospitals' 2011 outbreak-associated plasmid among CPE collected from 2011 to 2021.

Background: Dermatofibrosarcoma protuberans (DFSP) is a rare, low-grade fibrohistiocytic tumor with malignant potential. It is considered to have a high local recurrence rate due to the characteristic invasion of the finger-like lesion into the soft tissues.
Method: This retrospective study presents details of 20 DFSP patients with a history of surgery and a long follow-up period.
Healthy Lifestyle Care vs Guideline-Based Care for Low Back Pain: A Randomized Clinical Trial.

University Centre for Rural Health, School of Health Sciences, University of Sydney, Lismore, New South Wales, Australia.
Importance: An unhealthy lifestyle is believed to increase the development and persistence of low back pain, but there is uncertainty about whether integrating support for lifestyle risks in low back pain management improves patients' outcomes.
Objective: To assess the effectiveness of the Healthy Lifestyle Program (HeLP) compared with guideline-based care for low back pain disability.
Design, Setting, And Participants: This superiority, assessor-blinded randomized clinical trial was conducted in Australia from September 8, 2017, to December 30, 2020, among 346 participants who had activity-limiting chronic low back pain and at least 1 lifestyle risk (overweight, poor diet, physical inactivity, and/or smoking), referred from hospital, general practice, and community settings.

Background: Although the survival rate for thyroid cancer is high, a nursing intervention that enhances autonomous motivation is needed for patients with jobs to improve their long-term self-management abilities in the early postoperative period.
Objectives: This study aims to develop a mobile application (app) based on the Self-Determination Theory for patients returning to work after thyroid cancer surgery and to verify its effectiveness.
Methods: We developed an app to promote self-management and verify its effectiveness after 12 weeks in early outpatients who underwent thyroid cancer surgery through a randomized controlled trial design.

Safer chemical alternatives to bisphenol (BP) have been a major pursuit of modern green chemistry and toxicology. Using a chemical similarity-based approach, it is difficult to identify minor structural differences that contribute to the significant changes of toxicity. Here, we used omics and computational toxicology to identify chemical features associated with BP analogue-induced embryonic toxicity, offering valuable insights to inform the design of safer chemical alternatives.
