Utility of Retroperitoneal Laparoscopic Surgery for Retroperitoneal Tumors.

Introduction: Retroperitoneal laparoscopic surgery for benign retroperitoneal tumors is often challenging because of variations in the tumor location and size. In this study, we present a retroperitoneal laparoscopic resection technique used at our institution to treat benign retroperitoneal tumors.

Materials And Methods: This retrospective case series included nine consecutive patients who underwent retroperitoneal laparoscopic tumor resection between 2011 and 2023.

The Thermal-Stable LH1-RC Complex of a Hot Spring Purple Bacterium Powers Photosynthesis with Extremely Low-Energy Near-Infrared Light.

is a hot spring purple nonsulfur phototrophic bacterium that contains bacteriochlorophyll (BChl) . Here, we present a 2.21 Å cryo-EM structure of the thermostable light-harvesting 1-reaction center (LH1-RC) complex from .

Impact of a multicomponent strategy including decentralized molecular testing for tuberculosis on mortality: planned analysis of a cluster-randomized trial in Uganda.

Background: Rapid diagnosis of tuberculosis (TB) is important for improving outcomes and reducing transmission. Previous studies assessing the impact of Xpert MTB/RIF (Xpert), a molecular assay that provides results within 2 h, on mortality have been inconclusive. In this planned analysis of a pragmatic cluster-randomized trial in Uganda, we assessed whether a multicomponent strategy, including decentralized Xpert testing, decreased mortality among adults evaluated for TB.

Imaging using diffusion-weighted whole-body imaging with background signal suppression for methotrexate-associated lymphoproliferative disorder: A case report.

Patients with rheumatoid arthritis (RA) receiving immunosuppressive therapy including methotrexate (MTX), are at risk of developing lymphoproliferative disorder (LPD). Herein, we report the case of a 61-year-old man who has been treated with MTX and sulfasalazine for seropositive RA since the age of 52. He underwent diffusion-weighted whole-body imaging with background signal suppression (DWIBS), which revealed high-intensity lesions in the affected lymph nodes of the cervical, clavicular, and axillary regions.

C-reactive Protein-based Screening of People with Tuberculosis Symptoms: A Diagnostic Accuracy Study.

: C-reactive protein (CRP)-based tuberculosis (TB) screening is recommended for people with HIV (PWH). However, its performance among people without HIV and in diverse settings is unknown. : In a multi-country study, we aimed to determine whether CRP meets the minimum accuracy targets (sensitivity ≥90%, specificity ≥70%) for an effective TB screening test.
