Introduction: The guidelines stress the importance of cardiac surgery in the management of life-threatening complications arising from lead removal.
Aim: To delineate the roles of the cardiac surgeon during transvenous lead extraction (TLE).
Material And Methods: 3207 patients (38.7% F), average age 65.7 years, underwent the extraction of PM/ICD leads using standard non-powered mechanical systems within the last 14 years.
Results: Procedural success 96.1%, clinical success 97.8%, procedure-related death 0.18%, major complications 1.9% (cardiac tamponade 1.2%, hemothorax 0.2%, tricuspid valve damage 0.3%, stroke and pulmonary embolism < 1%). The roles for cardiac surgery in TLE have been categorized into five areas: 1. Emergency cardiac surgery (1.18% of all patients), 2. Late surgical intervention (TLE-related tricuspid valve dysfunction) (0.44%), 3. Cardiac surgery complementing partially successful TLE (0.68%: removal of lead fragments), 4. Epicardial pacemaker implantation through sternotomy for the above-mentioned reasons (0.65%), 5. Delayed surgical intervention after TLE to place epicardial LV leads (0.53%). Additionally, surgical experience can help in prevention and treatment of wound infection after TLE.
Conclusions: Emergency cardiac surgery (mainly due to severe bleeding) is still the most frequent reason for intervention (33.63% (38/113) of all surgical procedures). The other areas of surgical interventions in lead management are: cardiac surgery complementing partially successful TLE, repair or replacement of the malfunctioning tricuspid valve secondary to lead extraction and implantation of permanent epicardial pacing leads after sternotomy or epicardial left ventricle lead to optimize cardiac resynchronization. Experience of a single high-volume lead extraction center confirms the need for close collaboration between the cardiologist and the cardiac surgeon, whose role goes far beyond mere surgical standby.

Effect of exercise training on modulating the TH17/TREG imbalance in individuals with severe COPD: A randomized controlled trial.
Pulmonology

Laboratory of Experimental Therapeutics, LIM-20, Department of Clinical Medicine, School of Medicine, University of Sao Paulo, Sao Paulo, Brazil.
Background: Chronic obstructive pulmonary disease (COPD) induces an imbalance in T helper (Th) 17/regulatory T (Treg) cells that contributes to of the dysregulation of inflammation. Exercise training can modulate the immune response in healthy subjects.
Objective: We aimed to evaluate the effects of exercise training on Th17/Treg responses and the differentiation of Treg phenotypes in individuals with COPD.
Case report: Toxic epidermal necrolysis induced by tislelizumab in a patient with esophageal squamous cell carcinoma.

Department of Oncology, Ganzhou People's Hospital, Ganzhou, China.
Background: Immune checkpoint inhibitors (ICIs) have been widely applicated for the treatment of patients with advanced esophageal cancer. Skin-related adverse reactions are frequent with ICIs, with toxic epidermal necrolysis (TEN) being a severe and potentially life-threatening cutaneous reaction.
Case Presentation: We present a case of a 70-year-old male with locally advanced esophageal cancer who developed severe toxic epidermal necrolysis (TEN) after 18 days of tislelizumab combined with chemotherapy.

Department of Pathology and Genetics, Laboratory of Cancer Medical Science, Hokuto Hospital, Obihiro, Hokkaido, Japan.
Background: Pancreatic cancer is highly aggressive and has a low survival rate primarily due to late-stage diagnosis and the lack of effective early detection methods. We introduce here a novel, noninvasive urinary extracellular vesicle miRNA-based assay for the detection of pancreatic cancer from early to late stages.
Methods: From September 2019 to July 2023, Urine samples were collected from patients with pancreatic cancer (n = 153) from five distinct sites (Hokuto Hospital, Kawasaki Medical School Hospital, National Cancer Center Hospital, Kagoshima University Hospital, and Kumagaya General Hospital) and non-cancer participants (n = 309) from two separate sites (Hokuto Hospital and Omiya City Clinic).
Spontaneous Heterotopic Pregnancy: A Case Report of a Rare and Critical Obstetric Condition.

Obstetrics and Gynecology, Al Thagher General Hospital, Jeddah, SAU.
Heterotopic pregnancy is defined as the concurrent presence of both an intrauterine pregnancy and an extrauterine (typically ectopic) pregnancy. This report presents the case of a 36-year-old female patient who presented to the emergency department with lower abdominal pain. A comprehensive evaluation, including transabdominal and transvaginal ultrasound imaging, revealed a heterotopic pregnancy at an estimated gestational age of six weeks and two days.

Introduction Preoperative fasting is essential in surgical care to reduce the risk of pulmonary aspiration during anesthesia. International guidelines, such as those from the American Society of Anesthesiologists (ASA) and the European Society of Anaesthesiology (ESA), recommend fasting durations of six hours for solids and two hours for clear liquids. However, adherence to these guidelines often varies in clinical practice, leading to prolonged fasting times that can negatively impact patient outcomes, including dehydration, hypoglycemia, discomfort, and delayed recovery.
