Objective: To describe the characteristics of patients with acute respiratory distress syndrome due to bilateral COVID-19 pneumonia on invasive mechanical ventilation (IMV) and analyze the effect of prolonged prone decubitus > 24 h (PPD) compared to prone decubitus < 24 h (PD).

Design: Retrospective observational descriptive study. Uni and bivariate analysis.

Setting: Department of Intensive Care Medicine. General University Hospital of Elche.

Participants: Patients with SARS-CoV-2 pneumonia (2020-2021) in VMI for moderate-severe acute respiratory distress syndrome, ventilated in PD.

Interventions: IMV. PD maneuvers.

Main Variables Of Interest: Sociodemographic; analgo-sedation; neuromuscular blockade; PD (duration), ICU stay and mortality, days of IMV; non-infectious complications; health care-associated infections.

Results: Fifty-one patients required PD and of these 31 (69.78%) required PPD. No differences were found in patient characteristics (sex, age, comorbidities, initial severity, antiviral and anti-inflammatory treatment received). Patients on PPD had lower tolerance to supine ventilation (61.29 vs. 89.47%,  = 0.031), longer hospital stay (41 vs. 30 days,  = 0.023), more days of IMV (32 vs. 20 days,  = 0.032), longer duration of neuromuscular blockade (10.5 vs. 3 days,  = 0.0002), as well as a higher percentage of episodes of orotracheal tube obstruction (48.39 vs. 15%,  = 0.014).

Conclusions: PPD was associated with higher resource use and complications in patients with moderate-severe acute respiratory distress syndrome by COVID-19.

More micrometastases, more recurrence? The role of qPCR of PSA mRNA in lymph nodes during prostatectomy.

World J Urol

January 2025

Department of Urology, Urooncology, Robot-assisted and Focal Therapy, University Hospital Magdeburg, Otto-von Guericke University Magdeburg, Leipziger Str. 44, 39120, Magdeburg, Germany.

Background And Objectives: Radical prostatectomy is a standard treatment for prostate cancer, yet about 30% of patients experience rising biochemical markers within a decade post-surgery. Pelvic lymph node sampling during prostatectomy assesses potential lymph node metastases, but standard histological assessments, which typically examine only 2-3 tissue sections, often miss occult metastases. This study assesses the effectiveness of qPCR in detecting PSA coding KLK3 mRNA for identifying lymph node metastases post-prostatectomy and explores the correlation between PSA-mRNA and biochemical recurrence.

Objectives: Past studies have shown the efficacy of spinal targeted drug delivery (TDD) in pain relief, reduction in opioid use, and cost-effectiveness in long-term management of complex chronic pain. We conducted a survey to determine treatment variables associated with patient satisfaction.

Materials And Methods: Patients in a single pain clinic who were implanted with Medtronic pain pumps to relieve intractable pain were identified from our electronic health record.

Department of Hepatobiliary Surgery, Shandong Provincial Hospital, Shandong First Medical University, 324 Jingwuweiqi Road, Jinan, 250021, China.

Purpose: To compare outcomes of LLR in VI/VII of the liver in Left-lateral Decubitus Jackknife Position (LDJP) and traditional Supine Position (SP). We used propensity score matching (PSM) to analyze clinical outcomes.

Patients & Methods: This study retrospectively analyzed patients undergoing LLR for liver tumors in segments VI and/or VII at Shandong Provincial Hospital from 2018 to 2023.

Electric vehicles (EVs) rely heavily on lithium-ion battery packs as essential energy storage components. However, inconsistencies in cell characteristics and operating conditions can lead to imbalanced state of charge (SOC) levels, resulting in reduced capacity and accelerated degradation. This study presents an active cell balancing method optimized for both charging and discharging scenarios, aiming to equalize SOC across cells and improve overall pack performance.

Gastrointestinal lesions of eosinophilic granulomatosis with polyangiitis: a prediction model and clinical patterns.

Arthritis Res Ther

January 2025

Department of Rheumatology and Clinical Immunology, Peking Union Medical College Hospital, the Ministry of Education Key Laboratory, Chinese Academy of Medical Sciences & Peking Union Medical College, National Clinical Research Center for Dermatologic and Immunologic Diseases, Beijing, China.

Objective: Severe gastrointestinal lesions are associated with a poor prognosis in eosinophilic granulomatosis with polyangiitis (EGPA). The goal of this study was to develop an effective predictive model for gastrointestinal lesions and to examine clinical patterns, associated factors, treatment, and outcomes of gastrointestinal lesions in EGPA.

Methods: We retrospectively enrolled 165 EGPA patients.
