Association of Omnivorous and Vegetarian Diets With Antioxidant Defense Mechanisms in Men.

Background Evidence that a vegetarian diet rich in antioxidants contributes to cardiovascular health are growing, however, the underlying molecular mechanisms remain unknown. HO-1 (heme-oxygenase-1), a marker of adaptive response, is protective against oxidative stress and has shown cardioprotective effects. Therefore, we evaluated circulating HO-1 levels and the effect of plasma from omnivorous and vegetarians in endothelial cells (human umbilical vein endothelial cells) on modulating NRF2 (nuclear factor erythroid 2-like 2)/HO-1 and nitric oxide production.

Emergency CT of abdominal complications of ingested fish bones: what not to miss.

Fish bones are the most commonly ingested structures and the most common cause of foreign body perforation of the gastrointestinal tract (GIT). Clinical presentation of foreign body GIT perforation is nonspecific, in many cases with clinical signs of acute abdomen, which can mimic appendicitis, diverticulitis, ulcer peptic disease, and other common inflammatory conditions. Besides, patients commonly do not refer that a fish bone was swallowed.

The Collaborative Ocular Tuberculosis Study (COTS) Consensus (CON) Group Meeting Proceedings.

An international, expert led consensus initiative was set up by the Collaborative Ocular Tuberculosis Study (COTS) group to develop systematic, evidence, and experience-based recommendations for the treatment of ocular TB using a modified Delphi technique process. In the first round of Delphi, the group identified clinical scenarios pertinent to ocular TB based on five clinical phenotypes (anterior uveitis, intermediate uveitis, choroiditis, retinal vasculitis, and panuveitis). Using an interactive online questionnaires, guided by background knowledge from published literature, 486 consensus statements for initiating ATT were generated and deliberated amongst 81 global uveitis experts.

Asthma, allergic sensitization and lung function in sickle cell disease.

Background: Pulmonary disease is a frequent acute and chronic manifestation in sickle cell disease (SCD), presenting high morbidity and mortality.

Objectives: To identify the prevalence and association of asthma, allergic sensitization and altered pulmonary function in patients with SCD (SS and Sβ).

Methods: A single-center, cross-sectional study was conducted, in which 70 patients with SCD and 44 controls, aged six to 18 years, responded to the questionnaire of the International Study of Asthma and Allergies in Childhood (ISAAC), complemented with an anamnesis regarding the associated clinical outcomes.

University Hospital Financial Status Does Not Influence Subjective Perception of General Surgery Residents on Training Adequacy.

Background: Surgical residency training is a complex and costly task. Hospital economic health is dependent on different variables, but it is especially linked to the country macroeconomics that may be extremely fluctuating, especially in underdeveloped countries. This study analyzed the correlation between a single-center university hospital financial status and subjective perception of general surgery residents on program support and adequacy.

Loss of Potential Donors Due to Hemodynamic Maintenance.

Background: Statistics indicate low utilization of potential donors, where only about one-third are converted into actual donors. In this context, it is plausible to argue that many potential donors are not hemodynamically stable for harvesting multiple organs since the procedures for maintaining parameters of stability may not be a priority in all critical care units in the country. Thus, it is necessary to identify losses of potential donors due to hemodynamic maintenance since reversing this situation enable minimizing mortality on waiting lists.

Effects of surgically assisted rapid maxillary expansion on the modification of the pharynx and hard palate and on obstructive sleep apnea, and their correlations.

Purpose: To investigate the changes induced by surgically assisted rapid maxillary expansion (SARME) on palate and pharynx morphology as well as the correlation of these changes with the improvement of obstructive sleep apnea (OSA).

Materials And Methods: The study was conducted in 16 patients, seven women and nine men, aged on average 40.23 ± 10.

Fixed-combination Bimatoprost/Brimonidine/Timolol in Glaucoma: A Randomized, Masked, Controlled, Phase III Study Conducted in Brazil.

Purpose: Many patients with open-angle glaucoma eventually require >2 medications to lower their intraocular pressure (IOP). Fixed-combination ophthalmic solutions can be advantageous in patients who require multiple medications, but the number of fixed combinations combining 3 complementary IOP-lowering agents remains limited. This study assessed the efficacy and safety of a triple fixed combination (TFC) of bimatoprost 0.

CD163 tumor-associated macrophage accumulation in breast cancer patients reflects both local differentiation signals and systemic skewing of monocytes.

Objectives: The accumulation of tumor-associated macrophages (TAMs) is correlated with poor clinical outcome, but the mechanisms governing their differentiation from circulating monocytes remain unclear in humans.

Methods: Using multicolor flow cytometry, we evaluated TAMs phenotype in 93 breast cancer (BC) patients. Furthermore, monocytes from healthy donors were cultured in the presence of supernatants from dilacerated primary tumors to investigate their differentiation into macrophages (MΦ) .
