Construction and Surgical Training of Coronary Anastomosis on a Low-Cost Portable Simulator: Experience in a Peruvian Multicenter Study.

Introduction: The operating room is no longer the ideal place for early surgica training of cardiothoracic surgery residents, forcing the search for simulation-based learning options. The study's aim was the construction and surgicaltraining of coronary anastomosis in a portable, low-cost, homemade simulator.

Methods: This is an observational, analytical, and multicenter study.

Life-threatening hypercalcemia in a child with vitamin D intoxication due to parental self-medication: A case report.

Vitamin D is essential for bone metabolism and has gained popularity since the general population is now more aware of its benefits. Unfortunately, the availability of unregulated vitamin D formulations without prescription increases the risk of inadvertently ingesting excessive doses of vitamin D. Reports of pediatric cases of vitamin D toxicity are scarce in the world literature.

Outcomes and Survival for Early-Stage Non-Small Cell Lung Cancer Following Wedge Resection or Lobectomy: A Propensity Score-Matched Analysis Using a Novel Peruvian Registry.

Background: Using a previously unreported Peruvian registry of patients treated for early-stage non-small cell lung cancer (NSCLC), this study explored whether wedge resection and lobectomy were equivalent regarding survival and impact on radiologic-pathologic variables.

Methods: This observational, analytical, longitudinal study used propensity score-matched (PSM) analysis of a single-center retrospective registry of 2,570 patients with pathologic stage I-II NSCLC who were treated with wedge resection (n=1,845) or lobectomy (n=725) during 2000-2020. After PSM, 650 cases were analyzed (resection, n=325; lobectomy, n=325) through preoperative and clinical variables, including patients with ≥1 lymph node removed.

Peritoneal Lymphomatosis in a Pediatric Patient: A Peruvian Case Report.

While NHL commonly affects lymph nodes, peritoneal lymphomatosis causing ascites is rare in pediatric patients. We present a unique case of DLBC lymphoma in a Peruvian child presenting as ascites associated with peritoneal lymphomatosis. The 11-year-old boy was admitted with ascites and dyspnea.

Novel Biomarkers for the diagnosis of diabetic nephropathy.

Diabetes mellitus and its complications are a known public health problem nowadays. Diabetic nephropathy is one of the main complications and the result of multiple mechanisms, including: activation of the renin-angiotensin-aldosterone system, formation of advanced glycation end products and chronic inflammation that led to glomerular and tubulo-interstitial damage producing mesangial expansion and glomerulosclerosis, which finally results in chronic kidney disease. Early detection of diabetic nephropathy is essential for adequate intervention to stop, or at least slow down its progression.

3D impression to facilitate in situ surgical renal segmental artery aneurysm repair: A novel open approach option for an unusual vascular condition.

Objectives: Renal Artery Aneurysms (RAA) affect approximately 0.01%-0.97% of the population.

Efficacy and Safety of Celiac Plexus Neurolysis in the Treatment of Chronic Pain Secondary to Oncological Pathology of the Upper Hemiabdomen: A Systematic Review and Meta-Analysis.

Objectives: The management of chronic pain among patients with abdominal cancer is complex; against that, the neurolysis of the celiac plexus (CPN) is the best technique at the moment o determine the efficacy and safety in the treatment of chronic pain secondary to oncological pathology of the upper abdomen.

Material And Methods: This was a systematic review of controlled clinical trials between 2000 and 2021, in the sources MEDLINE/PubMed, Cochrane, Scopus, Web of Science, and Google Scholar. Three independent evaluators analysed the results of the bibliographical research.

Thoracic Fetiform Teratoma: A Case Report of a Very Rare Entity in a Peruvian Hospital.

Mature fetiform teratoma, or homunculus, is a term coined for a rare variant of teratoma with a prevalence of 0.01% of teratomas. There have been very few cases reported in the world, and its thoracic presentation is extremely unusual.

Survey on initial management of acute pancreatitis in Latin America.

Objective: The population of Latin America harbors the highest incidence of gallstones and acute biliary pancreatitis, yet little is known about the initial management of acute pancreatitis in this large geographic region.

Participants And Methods: We performed a post hoc analysis of responses from physicians based in Latin America to the international multidisciplinary survey on the initial management of acute pancreatitis. The questionnaire asked about management of patients during the first 72h after admission, related to fluid therapy, prescription of prophylactic antibiotics, feeding and nutrition, and timing of cholecystectomy.

Evaluating three biomarkers as prognostic factors of in-hospital mortality and severity in heart failure: A prospective cohort.

Objective: To identify the relationship between red blood cell distribution width (RDW, %), interleukin-6 (IL-6) (pg/ml), high sensitivity-c-reactive protein (hs-CRP) (mg/l), in-hospital mortality and disease severity among patients with heart failure (HF).

Methods: Prospective cohort. We included adults diagnosed with acute non-ischemic HF in 2015.

Arteriographic patterns of peripheral arterial disease in lower limbs in a Peruvian cohort of patients.

Introduction: There is currently no universal and uniform pattern of peripheral arterial disease (PAD) in the lower limbs; however, it is influenced by various cardiovascular factors of the individual. The objective of this study was to identify the arteriographic patterns of PAD in the lower limbs according to cardiovascular factors in a Peruvian cohort of patients.

Methods: This is an analytical, observational, and retrospective study.

Bentall surgery and total arch repair with debranching of supra-aortic vessels: a case report.

Background: The surgical approach to pathologies of the Ascending Thoracic Aorta (ATA) that compromise aortic root and the aortic arch is currently one of the most complex interventions in the spectrum of cardiac surgery, where circulatory arrest with cerebral perfusion plays an important role for Success postoperative and patient survival.

Case Presentation: We present the case of a 57-year-old patient with the only history of arterial hypertension and an ATA Aneurysm that compromised segment of the aortic root up to segment 2 of the aortic arch. A successful Bentall surgery was performed, debranching supra-aortic vessels with Total Circulatory Arrest with Deep Hypothermic Cerebral Perfusion-Antegrade Bilateral.

Ankle-brachial index: more than a diagnostic test?

The ankle-brachial index (ABI) is the relationship between the systolic blood pressure taken at the ankle level and the brachial artery. A pathological ABI (<0.90 or >1.
