Effect of dupilumab on otitis media associated with eosinophilic chronic rhinosinusitis.

Braz J Otorhinolaryngol

January 2025

Tokushima University Graduate School, Institute of Biomedical Sciences, Department of Otolaryngology-Head and Neck Surgery, Tokushima, Japan.

Objective: Eosinophilic Otitis Media (EOM) is an intractable disease caused by type 2 inflammation, such as Eosinophilic Chronic Rhinosinusitis (ECRS) and bronchial asthma. Biologics have recently been used to treat ECRS and bronchial asthma. Biologics are not indicated for EOM; however, because approximately 10% of ECRS cases has concomitant EOM, concomitant EOM improvement has been observed when dupilumab is administered for ECRS.

Open abdomen treatment (OAT) is associated with significant morbidity and mortality. In cases where primary or delayed fascial closure cannot be achieved, vacuum-assisted wound closure and mesh-mediated fascial traction are indicated, which often result in a planned ventral hernia. If secondary skin closure is not feasible, common treatment of granulated abdominal defects involves split-thickness skin-grafting or healing by secondary intention leading to significant scarring and sometimes mutilating defects.

Thinning of anterolateral thigh flap is challenging. Anatomical studies have shown variations in arterial branching patterns in the subcutaneous layer, which were suspected to be the reason for the high frequency of thinning failures. We attempted to visualize subcutaneous arterial courses preoperatively and perform thinning of perforator flaps using this information appropriately.

Introduction: Chronic nausea and vomiting are symptoms of a wide range of gastrointestinal and non-gastrointestinal conditions. Diagnosis can be challenging and requires a systematic and well-structured approach. If the initial investigation for structural, toxic and metabolic disorders is negative, digestive motility and gut-brain interaction disorders should be assessed.

Protocol to detect neutral lipids with BODIPY staining in myeloid-derived suppressor cells in mouse mammary tumors.

STAR Protoc

January 2025

Department of Surgery, Sylvester Comprehensive Cancer, University of Miami Miller School of Medicine, Miami, FL 33136, USA. Electronic address:

Neutral lipids affect the immunosuppressive function of myeloid-derived suppressor cells (MDSCs). Here, we present a protocol for measuring neutral lipids in MDSCs using BODIPY from mouse mammary tumor derived from triple-negative breast cancer cells, 4T1, which is applicable to other mammary tumors of interest. We describe steps for 4T1 cell culture, single-cell isolation from tumors, staining of cells with antibodies and BODIPY, and flow cytometry.

Dual α-globin-truncated erythropoietin receptor knockin restores hemoglobin production in α-thalassemia-derived erythroid cells.

Cell Rep

January 2025

Department of Surgery, University of California, San Francisco, San Francisco, CA 94143, USA; Eli & Edythe Broad Center for Regeneration Medicine, University of California, San Francisco, San Francisco, CA 94143, USA; Department of Bioengineering & Therapeutic Sciences, University of California, San Francisco, San Francisco, CA 94158, USA. Electronic address:

The most severe form of α-thalassemia results from loss of all four copies of α-globin. Postnatally, patients face challenges similar to β-thalassemia, including severe anemia and erythrotoxicity due to the imbalance of β-globin and α-globin chains. Despite progress in genome editing treatments for β-thalassemia, there is no analogous curative option for α-thalassemia.

Introduction: The burden of severe asthma on patients, especially on those with concomitant chronic rhinosinusitis with nasal polyps (CRSwNP), is substantial. Treatment intensification with oral corticosteroids is a common strategy for managing severe asthma exacerbations; however, prolonged exposure to systemic corticosteroids is associated with multisystem toxicity. This study aimed to quantify the association between oral corticosteroid use and annual asthma-related costs in patients with severe asthma with or without CRSwNP.

This study aims to investigate the causal associations between CPLRs and papillary thyroid cancer (PTC), focusing on their potential implications in drug resistance mechanisms.

Methods: Genetic data for 2821 CPLRs were obtained from the GWAS and FinnGen databases.

Restoration of miR-200 expression suppresses proliferation and mobility of pancreatic cancer cell.

Naunyn Schmiedebergs Arch Pharmacol

January 2025

Department of General Surgery, Tianjin First Center Hospital, Tianji, 300384, China.

A number of various human malignancies have been associated with abnormal microRNAs (miRNA) expression. There are evidence that miR-200 operates as both tumor suppressor and an onco-miR in a variety of tumors. In this study, we evaluated the effects of miR-200 on the proliferation and migration of pancreatic cancer cells, as well as the underlying molecular pathways.

Robotic surgery is extensively used for rectal cancer treatment. Nonetheless, studies on whether to preserve the left colonic artery (LCA) during robotic rectal cancer surgery to reduce complications remain scarce and controversial. This study compared short-term outcomes of high tie (HT) and low tie (LT) ligation of the inferior mesenteric artery in 455 patients undergoing robotic rectal cancer surgery between May 2018 and July 2022.

Objective: To establish an arterial spin labeling (ASL) protocol for rat livers that improves data reliability and reproducibility for perfusion quantification.

Methods: This study used respiratory-gated, single-slice, FAIR-based ASL imaging with multiple inversion times (TI) in rat livers. Quality assurance measures included: (1) introduction of mechanical ventilation to ensure consistent respiratory cycles by controlling the respiratory rate (45 bpm), tidal volume (10 ml/kg), and inspiration: expiration ratio (I:E ratio, 1:2), (2) optimization of the trigger window for consistent trigger points, and (3) use of fit residual map and coefficient of variance as metrics to assess data quality.

Purpose: Trauma and orthopaedic (T&O) surgery relies on medical implants and materials, often resulting in metalwork wastage (prosthesis, screws, nails, and plates). This places an economic strain on healthcare services and the environment. Our primary outcome is to quantify the implant wastage across the literature, and secondarily investigate the associated costs in this specialty.

Purpose Of Review: Effective pain management in cardiac surgery presents as a continuous challenge related to the intensity of postoperative pain and reliance on opioid therapy. The dependance of opioid-based therapies is concerning, as these therapies carry risk future addiction and potential severe side effects. The transversus thoracic plane block (TTPB) has emerged as a promising regional anesthesia technique that blocks the anterior branches of the intercostal nerves in the chest wall, potentially providing improved analgesia for cardiac surgery patients.

Purpose Of Review: The rhomboid intercostal and subserratus plane (RISS) block is an effective, safer alternative for managing postoperative acute pain following abdominal surgeries. The RISS block offers several advantages over traditional approaches, including reduced incidence of puncture-related complications, lower rates of systemic opioid consumption, and more consistent analgesic coverage of lower thoracic dermatomes.

Recent Findings: Despite a favorable safety profile, the RISS block carries potential risks, such as pneumothorax and local anesthetic systemic toxicity, particularly when long-acting anesthetics such as bupivacaine or ropivacaine are used.

The effect of epilepsy surgery on tonic-clonic seizures.

Epilepsia

January 2025

Jefferson Comprehensive Epilepsy Center, Department of Neurology, Thomas Jefferson University, Philadelphia, Pennsylvania, USA.

Objective: Epilepsy surgery outcomes tend to be judged by the percentage in seizure reduction without considering the effect on specific seizure types, particularly tonic-clonic seizures, which produce the greatest morbidity and mortality. We assess how often focal to bilateral tonic-clonic seizures (BTCS) stop and how often they appear de novo after epilepsy surgery.

Methods: Analysis of a prospectively maintained epilepsy surgery database between 1986 and 2022 that characterizes the burden of BTCS after resective epilepsy surgery.
