Background: Diabetes carries an increased risk of cardiovascular disease and thromboembolic events. Upon endothelial dysfunction, platelets bind to endothelial cells to precipitate thrombus formation; however, it is unclear which surface proteins regulate platelet-endothelium interaction. We and others have shown that peri/epicellular protein disulfide isomerase A1 (pecPDI) influences the adhesion and migration of vascular cells.

Background: Iron (Fe) supplementation is a critical component of anemia therapy for patients with chronic kidney disease (CKD). However, serum Fe, ferritin, and transferrin saturation, used to guide Fe replacement, are far from optimal, as they can be influenced by malnutrition and inflammation. Currently, there is a trend of increasing Fe supplementation to target high ferritin levels, although the long-term risk has been overlooked.

Background: Impulsivity is associated with serious detrimental consequences on physical, mental, behavioral and social aspects of health among patients with psychosis. The present prospective 12-month follow-up study aimed to determine the prevalence of highly impulsive individuals among Ultra High Risk (UHR) patients, how impulsivity evolves over the follow-up period, and whether impulsivity impacts clinical, psychological and functional outcomes in this population.

Method: UHR patients were invited to complete a battery of measurements at three-time points: at baseline, and at 6 and 12 months of follow-up.

Trauma is a leading cause of mortality and morbidity worldwide with high rates of disability in survivors. With improvements in care, rehabilitation of the trauma patient is a cornerstone to reducing sequelae. A lack of well-established hospital rehabilitation units and standardized protocols for managing posttraumatic injuries is a common problem in Latin American countries.

Metamaterial design for aortic aneurysm simulation using 3D printing.

3D Print Med

August 2024

Electrical Engineering Graduate Program, Telecommunications and Control Engineering Department, Polytechnic School, University of São Paulo, São Paulo, Brazil.

Introduction: The use of three-dimensional (3D) printed anatomic models is steadily increasing in research and as a tool for clinical decision-making. The mechanical properties of polymers and metamaterials were investigated to evaluate their application in mimicking the biomechanics of the aortic vessel wall.

Methodology: Uniaxial tensile tests were performed to determine the elastic modulus, mechanical stress, and strain of 3D printed samples.

Article Synopsis
  • The study aimed to assess the long-term surgical outcomes of ACL reconstruction in patients with and without preoperative anterolateral ligament (ALL) lesions, using MRI to identify these injuries.
  • Results indicated that patients with ALL injuries had a significantly higher failure rate of 14.3% compared to 4.6% in the control group, along with poorer knee function as measured by Lysholm scores.
  • Further analysis showed that while certain tests yielded similar results, patients with ALL injuries demonstrated worse knee stability as reflected by increased anteroposterior translation measurements.

Article Synopsis
  • - A study in Rio de Janeiro examined the prevalence and impact of long COVID among socially vulnerable communities, showing that 20% of participants felt unfully recovered and 22% experienced new or lingering symptoms.
  • - Key findings indicate 26% had worsened functional status, 32% noted a decline in quality of life, and symptoms like headache, cough, and fatigue were common, with dyspnoea (difficulty breathing) identified as a major predictor of bad outcomes.
  • - The results underscore significant physical and mental health challenges for those affected by COVID-19 in these communities, highlighting the need for targeted support and research in underrepresented populations.

Laboratório de Investigação Médica (LIM) 31, Universidade de São Paulo, São Paulo, Brazil; Serviço de Hematologia, Hemoterapia e Terapia Celular, Hospital das Clínicas HCFMUSP, Faculdade de Medicina, Universidade de São Paulo, São Paulo, Brazil; Hospital Vila Nova Star-Rede D'Or, São Paulo, Brazil; Department of Hematology, Churchill Hospital Oxford, Oxford University Hospitals, Oxford, UK.

High-dose therapy followed by autologous hematopoietic cell transplant (AHCT) remains a viable consolidation strategy for a subset of patients with relapsed or refractory (R/R) lymphomas. BEAM (carmustine, etoposide, cytarabine, and melphalan) is widely recognized as the predominant conditioning regimen due to its satisfactory efficacy and tolerability. Nevertheless, shortages of carmustine and melphalan have compelled clinicians to explore alternative conditioning regimens.

Multidisciplinary care is essential for the management of patients with psoriatic disease (PsD), considering the great range of cutaneous and musculoskeletal symptoms and the potential for associated comorbidities and extraarticular manifestations. Consequently, combined rheumatology/dermatology clinics represent a gold standard model of care for patients with PsD. Many challenges are associated with the establishment of these clinics in routine clinical practice.

Dietary Profile of Patients with Inflammatory Bowel Disease in Clinical Remission-A Preliminary Study.

Nutrients

July 2024

Laboratory of Nutrition and Metabolic Surgery (LIM-35), Department of Gastroenterology, Faculdade de Medicina, Hospital das Clinicas HCFMUSP, Universidade de São Paulo, São Paulo 13563-120, Brazil.

Imbalanced dietary intake is associated with the development of inflammatory bowel diseases (IBDs) and is often observed during the active phases of Crohn's disease (CD) and ulcerative colitis (UC). Cumulative data also suggest the potential for dietary manipulation in avoiding IBD relapse. However, there is a paucity of dietary data from patients in clinical remission to guide such an approach.

Background: There is a close relationship between obstructive sleep apnoea (OSA) and resistant hypertension (RH). However, studies assessing the long-term effect of diagnosing and treating OSA on blood pressure (BP) control in these patients are lacking.

Methods: To address this gap, we recruited 478 RH patients from hypertension units and followed them prospectively after they were screened for OSA through a sleep study.

Physical performance and plasma metabolic profile as potential prognostic factors in metastatic lung cancer patients.

Eur J Clin Invest

November 2024

Faculdade de Medicina, Instituto do Cancer do Estado de Sao Paulo ICESP, Hospital das Clínicas HCFMUSP, Universidade de Sao Paulo, Sao Paulo, Brazil.

Background: Low physical performance is associated with higher mortality rate in multiple pathological conditions. Here, we aimed to determine whether body composition and physical performance could be prognostic factors in non-small cell lung cancer (NSCLC) patients. Moreover, we performed an exploratory approach to determine whether plasma samples from NSCLC patients could directly affect metabolic and structural phenotypes in primary muscle cells.

Only a small number of studies have assessed structural differences between the two hemispheres during childhood and adolescence. However, the existing findings lack consistency or are restricted to a particular brain region, a specific brain feature, or a relatively narrow age range. Here, we investigated associations between brain asymmetry and age as well as sex in one of the largest pediatric samples to date (n = 4265), aged 1-18 years, scanned at 69 sites participating in the ENIGMA (Enhancing NeuroImaging Genetics through Meta-Analysis) consortium.

Ary Serpa Neto M.D., M.Sc., Ph.D.; Department of Critical Care Medicine and Cardio-Pulmonary Department, Pulmonary Division, São Paulo, Brasil; Department of Intensive Care, Australian and New Zealand Intensive Care Research Centre (ANZIC-RC), Monash University, Melbourne, Australia; and Department of Critical Care, Melbourne Medical School, University of Melbourne, Austin Hospital, Melbourne, Australia.

Background: The influence of high positive end-expiratory pressure (PEEP) with recruitment maneuvers on the occurrence of postoperative pulmonary complications after surgery is still not definitively established. Bayesian analysis can help to gain further insights from the available data and provide a probabilistic framework that is easier to interpret. The objective was to estimate the posterior probability that the use of high PEEP with recruitment maneuvers is associated with reduced postoperative pulmonary complications in patients with intermediate-to-high risk under neutral, pessimistic, and optimistic expectations regarding the treatment effect.
