Acute myeloid leukemia: challenges for diagnosis and treatment in Latin America.

Objective: to review the current diagnostic and therapeutic landscape of AML in Latin America as a reflection of other low- and middle-income countries and regions of the world. Encompassing both acute promyelocytic and non-promyelocytic disease types.

Methods: We reviewed the literature and study registries concerning epidemiological features of patients with AML/APL treated in Latin America, as well as evaluated diagnostic and genetic stratification and patient fitness assessment challenges, the importance of early mortality and supportive care capacity, intensive and non-intensive chemotherapy alternatives, consolidation, and maintenance strategies including novel agents and hematopoietic stem cell transplantation.

Comparison of Anterior Iliac Crest Versus Proximal Tibia Autologous Bone Graft Harvesting: A Systematic Review and Meta-Analysis.

Anterior iliac crest (AIC) is the preferred option for bone grafting; however, pain and complications are reported. Proximal tibia (PT) is a sourceful site for bone grafting with lower complications. MEDLINE, EMBASE, and Scopus were searched to identify studies comparing AIC and PT autograft procedure.

Reducción mamaria con implantes: serie de casos, técnica operatoria y resultados a largo plazo.

Background: Breast reduction techniques have been considered functional procedures proposed to reduce the volume and elevate the position of the nipple-areola complex. Traditionally these techniques were performed as mostly functional procedures. The main reasons for dissatisfaction after a reduction technique are breasts with a deflated appearance due to alteration of the shape, particularly of the upper pole, and simultaneously, the high frequency in the appearance of pseudoptosis in the medium and long term.

Expression of Trichinella spiralis serpin Tsp_01570 in Pichia pastoris: a first insight of its biomodulatory activity.

Serpins represent one of the most diverse families of serine protease inhibitors. Despite their complexity, they are virtually found in all organisms and play an important role in homeostasis processes such as blood coagulation, inflammation, fibrinolysis, immune responses, chromatin condensation, tumor suppression, and apoptosis. There has recently been particular interest in studying serpin functions in infection and inflammation, especially since more serpins from parasites have been identified and characterized.

Treatment of Ph-Negative Acute Lymphoblastic Leukemia in Adolescents and Young Adults with an Affordable Outpatient Pediatric Regimen.

Background: B-cell acute lymphoblastic leukemia is frequent in Hispanic adolescents and young adults. Outcomes of implementation of pediatric-inspired regimens in low-and middle-income countries are not well known.

Methods: In this study we treated 94 adolescents and young adults with a local BFM regimen designed to be affordable with the use of native L-asparaginase and mitoxantrone administered in an outpatient fashion, and the of BCR/ABL and measurable residual disease (MRD) determined by high sensitivity flow cytometry for risk stratification.

Association of rs4711998 of IL-17A, rs2275913 of IL-17A and rs763780 IL-17F gene polymorphisms with non-segmental vitiligo in a Mexican population.

Vitiligo is the most common depigmenting disease characterized by achromic macules due to selective loss of melanocytes. The pathogenesis remains poorly elucidated, and multiple hypotheses exist regarding its pathogenesis. Evidence suggests that stress on melanocytes can result in activation of the immune system, and involvement of both activated cluster of differentiation (CD8+) cytotoxic and CD4+ T cells in the dysfunction, depigmentation, and apoptosis of melanocytes.

Predictive factors for nephrectomy in renal trauma; assessment of a 6-point score.

Purpose: To evaluate predictive and associated risk factors for nephrectomy in renal trauma and assess a 6-point score for surgical decision-making.

Patients And Methods: This multicenter, retrospective, and observational study assessed 247 subjects with blunt or penetrating kidney trauma. Kidney injuries were classified according to the American Association for the Surgery of Trauma (AAST) Injury Scoring Scale.

Staph's Toxins IgE Antibodies and Its Relation to the Severity of Allergic Rhinitis.

Background: Specific IgE against can be found in approximately 40% of patients with allergies, also in patients without allergies because they may be sensitized. These antibodies are functional, and they can induce histamine release contributing to chronic pruritus which can worsen disease severity. The objective of this study was to compare levels of specific IgE against toxins in those populations.

Saroglitazar is noninferior to fenofibrate in reducing triglyceride levels in hypertriglyceridemic patients in a randomized clinical trial.

Saroglitazar, being a dual PPAR-α/γ agonist, has shown beneficial effect in diabetic dyslipidemia and hypertriglyceridemia. Fibrates are commonly used to treat severe hypertriglyceridemia. However, the effect of saroglitazar in patients with moderate to severe hypertriglyceridemia was not evaluated.

Effect of exogenous lipase on subcutaneous adipose tissue in a porcine animal model.

Background: Topical exogenous lipase has been approved for cosmetic use and has been used to mobilize fat from adipocytes. The objective of this study was to determine the effects of exogenous lipase in the subcutaneous adipose tissue.

Methods: Three different concentrations of exogenous lipase 1× (2 Units per ml), 5× (10 units per ml), and 10× (20 units per ml) were applied in a porcine model.

Outpatient allogeneic hematopoietic stem-cell transplantation: a review.

Hematopoietic stem-cell transplantation (HSCT) is usually performed in well-equipped units inside a hospital. The cost of this in-hospital transplant is usually very high; therefore, this procedure is more difficult to perform in low- and middle-income countries. Autologous outpatient HSCT is now a common procedure; however, outpatient allogeneic transplants are more complicated.

Venetoclax-based combinations for acute myeloid leukemia: optimizing their use in Latin-America.

Venetoclax combinations are a new standard for patients with acute myeloid leukemia (AML). We aimed to evaluate the safety and efficacy of these combinations in a period of accelerated approval in Latin-America. This observational study evaluated adults with acute myeloid leukemia who received venetoclax-based therapy in 11 public or private centers in Mexico and Peru for both newly diagnosed or relapsed and refractory AML.

Effect of Diameter and Fenestration Area of the Liposuction Cannula on the Viability of the Adipocytes.

Background: Loss of volume is perhaps the most frustrating problem of fat grafting. The process of fat grafting depends on different variables such as harvesting, processing, and injection techniques. Results between studies that evaluate the effect of the cannula size on fat graft survival have been controversial.
