The modernization of medical training at Escola Paulista de Medicina and the Rockefeller Foundation, 1956-1962.

The study analyses scientific knowledge circulation between Brazil and the United States, drawing on Rockefeller Foundation's funding to Escola Paulista de Medicina to modernize medical training. The chosen initial chronological landmark is 1956, when the foundation started funding the Brazilian institution, and the final year is 1962, deadline for spending the grants. The study's sources are dossiers collected at Rockefeller Archive Center, analyzed drawing on the evidential paradigm.

Expression of MMP-2, MMP-9 and TIMP-2 in pituitary tumors and their relationship with cavernous sinus invasion.

Objective: To evaluate the expression of matrix metalloproteinase-2 (MMP-2), MMP-9 and tissue inhibitor of metalloproteinase-2 (TIMP-2) in pituitary tumors and investigate their correlation with circulating plasma proteins and cavernous sinus invasion. In addition, the Ki-67 index was also assessed.

Methods: Seventy-four patients (37 females) with pituitary adenomas were included, with preoperative peripheral blood collected in 29 cases.

Passive sampling-derived aqueous concentrations of organotins and booster biocides in the largest Port of South America (Southeastern Brazil).

Organotin compounds (OTs) used to be the most widely used biocide in antifouling paint systems, but the International Maritime Organization (IMO) banned them because of their high environmental toxicity to non-target organisms. Currently, at least 25 active ingredients are being employed as biocides in antifouling paint formulations. In the present study, silicone rubber-based passive sampling was used to determine the freely dissolved concentrations (C) of 6 OTs and 4 booster biocides in the water column at the entrance of Santos Port's main navigation channel, the largest Port of South America (southeastern Brazil).

Assessment of Efficacy of Implant Screwdrivers' During Multiple Tightening/ Untightening Cycles. An in vitro Study.

Introduction: It is unclear the number of times a screwdriver may be reused without loosening its efficacy or inducing damage to implant screws while keeping appropriate torque values.

Objective: Evaluate the effect of the screwdriver and internal threads on the tightening efficacy by assessing the reverse torque value (RTV).

Methods: The efficacy was tested with four groups of screws: two titanium groups and two gold-platted (n=5).

The Impact of Clinical Features on Survival and Relapse of Patients Diagnosed With T-cell Acute Lymphoblastic Leukemia - a Multicenter Cohort Study.

Background: T-cell acute lymphoblastic leukemia (T-ALL) remains understudied compared to B-cell ALL, especially in Latin America. Different biology and response to chemotherapy have been described.

Methods: This retrospective multi-site cohort study analyzed data from 152 newly diagnosed T-ALL patients aged 15 years and above, between January 2010 and June 2022.

Chemical characterization, assessment of acute oral toxicity, and antinociceptive potential of the methanolic extract of (Arruda) Schott leaves from Brazil.

Background: (Arruda) Schott is popularly known as "aninga," "aningaçu," "aningaíba," and "aninga-do-igapó." Compresses and plasters made from the leaves of this medicinal plant are used to treat abscesses, tumors, and pain caused by stingray stings.

Aim Of The Study: This study aimed to chemically characterize the methanolic extract of leaves (MEMLL), as well as to verify their acute oral toxicity and antinociceptive potential.

Comparison Between Simple Batch and Fed-Batch Bioreactor Cultivation of Recombinant BCG.

: Tuberculosis continues to be a significant global health concern, causing 1.3 million deaths in 2022, particularly affecting children under 5 years old. The Bacillus Calmette-Guérin (BCG) vaccine, developed in 1921, remains the primary defense against tuberculosis but requires modernized production methods.

The impact of patient-facility language discordance on potentially inappropriate prescribing of antipsychotics in long-term care home in Ontario, Canada: a retrospective population health cohort study.

Background: Appropriate use of medication is a key indicator of the quality of care provided in long-term care (LTC). The objective of this study was to determine whether resident-facility language concordance/discordance is associated with the odds of potentially inappropriate prescribing of antipsychotics (PIP-AP) in LTC.

Methods: We conducted a population-based, retrospective cohort study of LTC residents in Ontario, Canada from 2010 to 2019.

High free sugars, insulin resistance, and low socioeconomic indicators: the hubs in the complex network of non-communicable diseases in adolescents.

Background: Noncommunicable diseases (NCDs) predominantly affect adults, but pathophysiological changes begin decades earlier, as a continuum, with initial events apparent in adolescence. Hence, early identification and intervention are crucial for the prevention and management of NCDs. We investigated the complex network of socioeconomic, behavioral, and metabolic factors associated with the presence of NCD in Brazilian adolescents.

The radiographic diversity of dental patterns among 7219 young individuals-a contribution to disaster victim identification.

The diversity of dental patterns is a fundamental topic in disaster victim identification. The current scientific literature, however, is scarce of data regarding young individuals. This study aimed to assess the radiographic diversity of dental patterns, considering missing, unrestored, and filled teeth in young individuals.

Degenerative mitral stenosis by echocardiography: presentation and outcome.

Aims: Degenerative mitral stenosis (DMS) is due to degenerative mitral annular calcification (MAC) and valvular calcification. However, DMS impacts on the outcome, and therefore, potential treatment needs are poorly known. We aimed at evaluating survival after DMS diagnosis by Doppler echocardiography in routine practice.

Nursing workload and severity of COVID-19 patients in the Intensive Care Unit.

Objective: To evaluate the workload and severity of patients in the Intensive Care Unit (ICU) with COVID-19.

Method: Cross-sectional, analytical study carried out in the ICU of a private hospital. All patients over the age of 18 with a diagnosis of COVID-19 admitted from September 2020 to June 2021 were included.

Antifreeze protein type I in the vitrification solution improves the cryopreservation of immature cat oocytes.

Oocyte cryopreservation is not yet considered a reliable technique since it can reduce the quality and survival of oocytes in several species. This study determined the effect of different concentrations of antifreeze protein I (AFP I) on the vitrification solution of immature cat oocytes. For this, oocytes were randomly distributed in three groups and vitrified with 0 μg/mL (G0, 0 μM); 0.

Lung cancer in First Nations, Inuit, and Métis peoples in Canada - a scoping review.

Lung cancer is one of the most commonly diagnosed cancers in Canada and a leading cause of cancer mortality. Lung cancer also affects First Nations, Inuit and Métis peoples significantly in Canada, which deserves further investigation as there is a literature gap on this topic. We sought to develop a deeper understanding of lung cancer diagnosis, incidence, mortality, and survival in First Nations, Inuit, and Métis peoples in Canada.

Hydropathic AF-2 variants in the androgen receptor gene among androgen insensitivity patients.

Background: Androgen insensitivity syndrome (AIS) is a common condition among individuals with differences of sexual development (DSD) and results from germline allelic variants in the androgen receptor (AR) gene. Understanding the phenotypic consequences of AR allelic variants that disrupt the activation function 2 (AF2) region is essential to grasping its clinical significance.

Objectives: This study aims to provide insights into the phenotypic characteristics and clinical impact of AR mutations affecting the AF2 region in AIS patients.

Methanolic Extract and Brominated Compound from the Brazilian Marine Sponge Are Neuroprotective and Modulate Inflammatory Profile of Microglia.

Neurodegenerative diseases involve neuroinflammation and a loss of neurons, leading to disability and death. Hence, the research into new therapies has been focused on the modulation of the inflammatory response mainly by microglia/macrophages. The extracts and metabolites of marine sponges have been presented as anti-inflammatory.
