Stroke continues to be a major adverse event in advanced congestive heart failure (CHF) patients after continuous-flow left ventricular assist device (CF-LVAD) implantation. Abnormalities in mitochondrial oxidative phosphorylation (OxPhos) have been critically implicated in the pathogenesis of neurodegenerative diseases and cerebral ischemia. We hypothesize that prior stroke may be associated with systemic mitochondrial OxPhos abnormalities, and impaired more in post-CF-LVAD patients with risk of developing new stroke.

Introduction: Abnormal lung function in people with multiple sclerosis (PwMS) could be considered as the result of muscle weakness or MS-specific structural central nervous system (CNS) abnormalities as a precipitant factor for the worsening of motor impairment or cognitive symptoms.

Methods: This is a cross-sectional observational study in PwMS. Forced spirometry was conducted, and normative metrics of forced vital capacity (FVC), forced expiratory volume in the first second (FEV), and the relation FEV1/FVC were calculated.

Introduction: High-dose melphalan (HD-Mel) has been successfully employed in autografting patients with multiple myeloma. An advantage of this regimen is that the total dose of Mel can be delivered in a single day, being particularly useful when non-frozen hematopoietic stem cells are employed in the autograft.

Material And Methods: All consecutive patients with R/R lymphomas, both HL and NHL studied and treated at two different centers were prospectively included in a study of ASCT employing a single dose of HD-Mel (200 mg/m).

There is data suggesting that the clinical behavior of multiple myeloma (MM) may be different in Latin Americans than in Caucasian or African-Americans, consistent with a less aggressive course of MM in Latinos. We analyzed the overall survival (OS) of 139 persons with MM in a single institution in México, as well the variables which were associated with long-term OS. Of all patients, the median OS was 11 years whereas the 5-year and 10-year OS were 75% and 55% respectively.

Article Synopsis
  • The study evaluated long-term outcomes for Hodgkin's lymphoma (HL) treatments in Mexico, focusing on simplified and affordable therapies used over 34 years.
  • It involved 88 patients treated with standard chemotherapy regimens (ABVD or MOPP), with outcomes tracked for an average of 128 months.
  • Results showed high overall survival rates of 83% for MOPP and 88% for ABVD, suggesting HL may be less aggressive in Mexicans compared to Caucasians, and combined chemotherapy was effective across all clinical stages.

The sticky platelet syndrome (SPS) was described by Mammen in 1983. Since then, scientists in several countries have identified the condition and published cases or series of patients, thus enabling the description of the prevalence of the inherited condition, its salient clinical features, and the treatment of the disease. The diagnosis of the SPS phenotype requires fresh blood samples and special equipment which is not available in all coagulation laboratories.

Introduction: We have previously shown that some patients present thrombocytopenia (less than 100 × 10/L platelets) in non-alcoholic fatty liver disease (NAFLD). To further explore the nature of this association, we have now analyzed the association of thrombocytopenia with neutropenia (less than 0.5 × 10/L granulocytes) in NAFLD.

Although therapeutic choices for patients with chronic lymphocytic leukemia (CLL) were once limited, treatment of this disease has vastly improved in the last decades. Consecutive CLL patients diagnosed in a single institution were analyzed. Treatment was withheld in persons with CLL Rai stage 0 or 1, until progression and in persons with stages 2-4, with a negative expression of ZAP-70 until progression.

Background: The treatment of patients with multiple myeloma (MM) has evolved in recent years, and the disease-associated prognosis has improved substantially. This improvement has been driven largely by the approval of novel agents, many of which are expensive and not universally available. Less expensive but effective approaches would be of value globally.
