The use of plasma exchange with albumin replacement in the management of Alzheimer's disease: a scoping review.

Introduction: AD is a progressive neurodegenerative disorder causing significant cognitive decline and impaired daily functioning. Current treatments offer only modest relief, and many amyloid-targeting therapies have failed, prompting exploration of alternative approaches such as PE with albumin replacement. Objectives: This scoping review systematically maps the literature on PE with albumin replacement in AD management, focusing on outcomes, methodologies, and reported benefits and risks. Methods: A comprehensive search in PubMed, supplemented by reference scanning and hand-searching, identified studies involving PE with albumin replacement in AD patients. Data charting and critical appraisal were conducted using standardized tools. Results: Seven primary studies from the AMBAR (Alzheimer Management by Albumin Replacement) trial met the inclusion criteria, consistently reporting improvements in cognitive function, positive neuroimaging results, and favorable neuropsychiatric outcomes. For instance, one study found a significant slowing of cognitive decline (p < 0.05) among patients receiving PE with albumin replacement. Another study showed better preservation of hippocampal volume and improved brain perfusion metrics in the treatment group (p < 0.05). The intervention was generally well-tolerated with manageable side effects. Conclusion: PE with albumin replacement is a promising therapeutic approach for AD, warranting further investigation to confirm its efficacy and safety across broader settings.

Unraveling the Tau Puzzle: A Brief Discussion on Biomarkers in Alzheimer's Disease.

This commentary provides an in-depth analysis of a recently published systematic review on 'Biomarkers of Tau Pathology in Alzheimer's Disease', elucidating insights into its implications for the field. This meta-analysis highlights the potential of plasma and CSF p-tau 181/231 as promising, non-invasive, and cost-effective diagnostic tools for patients suffering from AD continuum. The study comprehensively reviews the diagnostic potential of these p-tau isoforms, shedding light on their role in the precision diagnosis of Alzheimer's disease. Here we discuss the significance of these findings and the methodological nuances, emphasizing broader implications for advancing personalized medicine in neurodegenerative disorders.

The impact of outdoor pollution and extreme temperatures on asthma-related outcomes: A systematic review for the EAACI guidelines on environmental science for allergic diseases and asthma.

Air pollution is one of the biggest environmental threats for asthma. Its impact is augmented by climate change. To inform the recommendations of the EAACI Guidelines on the environmental science for allergic diseases and asthma, a systematic review (SR) evaluated the impact on asthma-related outcomes of short-term exposure to outdoor air pollutants (PM2.5, PM10, NO2, SO2, O3, and CO), heavy traffic, outdoor pesticides, and extreme temperatures. Additionally, the SR evaluated the impact of the efficacy of interventions reducing outdoor pollutants. The risk of bias was assessed using ROBINS-E tools and the certainty of the evidence by using GRADE. Short-term exposure to PM2.5, PM10, and NO2 probably increases the risk of asthma-related hospital admissions (HA) and emergency department (ED) visits (moderate certainty evidence). Exposure to heavy traffic may increase HA and deteriorate asthma control (low certainty evidence). Interventions reducing outdoor pollutants may reduce asthma exacerbations (low to very low certainty evidence). Exposure to fumigants may increase the risk of new-onset asthma in agricultural workers, while exposure to 1,3-dichloropropene may increase the risk of asthma-related ED visits (low certainty evidence). Heatwaves and cold spells may increase the risk of asthma-related ED visits and HA and asthma mortality (low certainty evidence).

FACEmemory®, an Innovative Online Platform for Episodic Memory Pre-Screening: Findings from the First 3,000 Participants.

BACKGROUND: The FACEmemory® online platform comprises a complex memory test and sociodemographic, medical, and family questions. This is the first study of a completely self-administered memory test with voice recognition, pre-tested in a memory clinic, sensitive to Alzheimer's disease, using information and communication technologies, and offered freely worldwide. OBJECTIVE: To investigate the demographic and clinical variables associated with the total FACEmemory score, and to identify distinct patterns of memory performance on FACEmemory. METHODS: Data from the first 3,000 subjects who completed the FACEmemory test were analyzed. Descriptive analyses were applied to demographic, FACEmemory, and medical and family variables; t-test and chi-square analyses were used to compare participants with preserved versus impaired performance on FACEmemory (cut-off = 32); multiple linear regression was used to identify variables that modulate FACEmemory performance; and machine learning techniques were applied to identify different memory patterns. RESULTS: Participants had a mean age of 50.57 years and 13.65 years of schooling; 64.07% were women, and 82.10% reported memory complaints with worries. The group with impaired FACEmemory performance (20.40%) was older, had less schooling, and had a higher prevalence of hypertension, diabetes, dyslipidemia, and family history of neurodegenerative disease than the group with preserved performance. Age, schooling, sex, country, and completion of the medical and family history questionnaire were associated with the FACEmemory score. Finally, machine learning techniques identified four patterns of FACEmemory performance: normal, dysexecutive, storage, and completely impaired. CONCLUSIONS: FACEmemory is a promising tool for assessing memory in people with subjective memory complaints and for raising awareness about cognitive decline in the community.

Is exposure to pollen a risk factor for moderate and severe asthma exacerbations?

Limited number of studies have focused on the impact of pollen exposure on asthma. As a part of the EAACI Guidelines on Environment Science, this first systematic review on the relationship of pollen exposure to asthma exacerbations aimed to bridge this knowledge gap in view of implementing recommendations of prevention. We searched electronic iPubMed, Embase, and Web of Science databases using a set of MeSH terms and related synonyms and identified 73 eligible studies that were included for systemic review. When possible, meta-analyses were conducted. Overall meta-analysis suggests that outdoor pollen exposure may have an effect on asthma exacerbation, but caution is needed due to the low number of studies and their heterogeneity. The strongest associations were found between asthma attacks, asthma-related ED admissions or hospitalizations, and an increase in grass pollen concentration in the previous 2-day overall in children aged less than 18 years of age. Tree pollen may increase asthma-related ED visits or admissions lagged up to 7-day overall in individuals younger than 18 years. Rare data show that among subjects under 18 years of age, an exposure to grass pollen lagged up to 3 days may lower lung function. Further research considering effect modifiers of pollen sensitization, hay fever, asthma, air pollution, green spaces, and pre-existing medications is urgently warranted to better evaluate the impacts of pollen on asthma exacerbation. Preventive measures in relation to pollen exposure should be integrated in asthma control as pollen increase continues due to climate change.

Non-alcoholic fatty liver disease and thrombocytopenia IV: its association with granulocytopenia

ABSTRACT Introduction: We have previously shown that some patients present thrombocytopenia (less than 100 × 109/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 × 109/L granulocytes) in NAFLD. Material and methods: Persons with NAFLD were prospectively accrued in the study after February 2018. The presence of NAFLD was defined by both serologic determinations (Fibromax ®) and liver transient elastography (TE/Fibroscan ®). Results: In 123 consecutive patients with NAFLD without cirrhosis, thrombocytopenia was identified in 20 (16%), whereas neutropenia was identified in 9 (7%). In the subset of 20 patients with NAFLD and thrombocytopenia, granulocytopenia was identified in 5 (25%), whereas in the subset of 9 patients with granulocytopenia, thrombocytopenia was identified in 5 (55%). We found a significant association between thrombocytopenia and both leukopenia and granulocytopenia (OR 8.25, 95% CI 1.9-34.2, p = 0.004). Conclusions: Both thrombocytopenia and neutropenia were identified in persons with NAFLD and, as there is a significant relationship between these two variables, we speculate that this finding may support the possibility of hypersplenism being involved in the cytopenias found in NAFLD without cirrhosis.

Families of doctors at Academia Nacional de Medicina de México.

INTRODUCTION: The decision to get involved in the study and practice of medicine is not easy. Within the scientific environment, achieving both professional and personal success requires a strict discipline, where effort becomes an essential part of daily life; in addition, having family support becomes crucial in order for not to lose hope when confronting the different adversities that arise during medical training. OBJECTIVE: To identify families where at least two members belong to the Academia Nacional de Medicina de México (ANMM). METHODS: A cross-sectional study was carried out to identify families of Mexican doctors where at least two members, consanguineous or in-laws, have been or are ANMM members through a review of 2017 ANMM Directory and personal contact with the different academics. RESULTS: Information on 45 families belonging to the ANMM was collected. CONCLUSIONS: From this study, it is possible to show the great influence that some doctors have in their family environment, which makes the study of medicine attractive as a life project.

Long term survival in multiple myeloma: a single institution experience in underprivileged circumstances.

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. The analysis of variables showed that the variable related with five-year survival was having hematopoietic stem cell transplantation (HSCT), whereas the variables related with 10-year survival were HSCT, age at diagnosis (patients younger than 50 survived longer), light chain type (kappa survived longer) and ISS stage (stage I patients survived longer). The only variable associated with both 5 and 10-year survival was HSCT. A plateau in the OS was reached after 10 years, both in grafted and non-grafted patients. We have confirmed the critical role of HSCT in the prognosis of persons with MM, independent of the induction treatment or the maintenance post-transplant, and we have identified a better prognosis in this cohort, as compared with African-Americans or Caucasians, since the proportion of long-term survivors in our group is seemingly better than those in other populations.

Long-term results of the treatment of Hodgkin's lymphoma in a resource-constrained setting: Real-world data from a single center.

BACKGROUND: The outcomes of Hodgkin´s lymphoma (HL) in México have not been widely reported. Simplified and affordable treatments have been adopted in middle-income countries. AIM: The aim was to evaluate long-used therapies for HL in México in a long-term basis. METHODS: In a 34-year time period, 88 patients with HL were treated at a single institution in México. Patients were treated with adriamycin bleomycin vinblastine and dacarbazine (ABVD) or mechlorethamine, vincristine, procarbazine, and prednisone (MOPP). Relapsed or refractory patients were given ifosfamide, carboplatin, and etoposide (ICE) followed by autologous or allogeneic stem cell transplants. RESULTS: Thirty-seven women and 51 men were included; the median age was 29 years. Patients were followed for a mean of 128 mo. The 310-mo overall survival (OS) was 83% for patients treated with MOPP and 88% for those treated with ABVD. The OS of patients who received autologous stem cell transplantation was 76% (330 mo) vs 93% (402 mo) in those who did not. CONCLUSION: HL may be less aggressive in Mexican population than in Caucasians. Combined chemotherapy renders acceptable results, regardless of clinical stage.

Primary Thrombophilia XVI: A Look at the Genotype of the Sticky Platelet Syndrome Phenotype.

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. In the era of molecular biology, up to now it has not been possible to define a clear association of the SPS phenotype with a specific molecular marker. Some molecular changes which have been described in platelet proteins in some persons with the phenotype of the SPS are here discussed. Nowadays, the SPS phenotype may be considered as a risk factor for thrombosis and most cases of the SPS developing vaso-occlussive episodes are the result of its coexistence with other thrombosis-prone conditions, some of the inherited and some of them acquired, thus leading to the concept of multifactorial thrombophilia. Ignoring all these evidence-based concepts is inappropriate, same as stating that the SPS is a nonentity simply because not all laboratories are endowed with adequate equipment to support the diagnosis.

Mantle cell lymphoma may have a different clinical course in Mexican Mestizos: Real-world data from a single center

ABSTRACT Background: The biology of some hematological diseases varies among different populations. No previous studies have evaluated the clinical behavior of mantle cell lymphoma (MCL) in México. Objective and Methods: This is a retrospective review of MCL cases seen in Mexico from January 2003 to June 2020. A total of 12 cases were identified. Results: There were nine males and three females; median age was 56 years. Eight patients had a high MCL international prognostic index score, one was intermediate, and three were low. Five patients had circulating malignant monoclonal cells. Initial treatment included rituximab, cyclophosphamide, daunorubicin, vincristine, and prednisone (R-CHOP) and CHOP. Subsequent treatment included hematopoietic stem cell transplantation in five patients; two were given maintenance therapy. Splenectomy was done in four patients. Median overall survival (OS) for all the patients has not been reached and exceeds 162 mos: OS at 162 mos was 56%. Achieving a complete remission (CR) after the first treatment was a significant prognostic factor, with a median OS exceeding 141 mos in patients achieving CR, and 16 mos among those not achieving CR (p = 0.0006). Conclusion: Some of MCL patients in Mexico have an indolent clinical course, particularly patients who achieve a CR to initial treatment and who undergo splenectomy.

The 1,000th Transplant for Multiple Sclerosis and Other Autoimmune Disorders at the HSCT-México Program: A Myriad of Experiences and Knowledge.

After gaining experience conducting both auto and allografts in persons with hematological diseases in the HSCT programs in Puebla and Monterrey, México, this study outlines subsequent program autografting patients with autoimmune conditions. The first transplant in multiple sclerosis was conducted in Puebla on July 5, 2006. From 2015 we increased activity autografting persons with autoimmune conditions in the two campuses of the HSCT-México program: Puebla and Monterrey. By December 6, 2020, patient number 1,000 in the program was autografted. In our experience, a significant reduction in the expanded disability status scale score was achieved in all of the three phenotypes of the disease (from a median of 5.1 to 4.5 points), whereas the response rate (defined as a decrease of at least 0.5 of EDSS score regardless of baseline EDSS, or unchanged EDSS) was 83, 78, and 73% after 12 months in the relapsing-remitting, primary-progressive and secondary-progressive forms of multiple sclerosis, respectively. In addition to analyzing the viability, safety, and efficacy of our method, this study contributes new knowledge to the field of both stem cell transplantation and multiple sclerosis.

INFUSION OF CONVALESCENT PLASMA IS ASSOCIATED WITH CLINICAL IMPROVEMENT IN CRITICALLY ILL PATIENTS WITH COVID-19: A PILOT STUDY.

BACKGROUND: The ideal treatment of coronavirus disease (COVID)-19 has yet to be defined, but convalescent plasma (CoPla) has been successfully employed. OBJECTIVE: The objective of the study was to study the safety and outcomes of the administration of CoPla to individuals with severe COVID-19 in an academic medical center. METHODS: Ten patients were prospectively treated with plasma from COVID-19 convalescent donors. RESULTS: Over 8 days, the sequential organ failure assessment score dropped significantly in all patients, from 3 to 1.5 (p = 0.014); the Kirby index (PaO2/FiO2) score increased from 124 to 255, (p < 0.0001), body temperature decreased significantly from 38.1 to 36.9°C (p = 0.0058), and ferritin levels also dropped significantly from 1736.6 to 1061.8 ng/ml (p = 0.0001). Chest X-rays improved in 7/10 cases and in 6/10, computerized tomography scans also revealed improvement of the lung injury. Decreases in C-reactive protein and D-dimer levels were also observed. Three of five patients on mechanical ventilation support could be extubated, nine were transferred to conventional hospital floors, and six were sent home; two patients died. The administration of CoPla had no side effects and the 24-day overall survival was 77%. CONCLUSIONS: Although other treatments were also administered to the patients and as a result data are difficult to interpret, it seems that the addition of CoPla improved pulmonary function.

Up to half of patients diagnosed with chronic lymphocytic leukemia in México may not require treatment.

Introduction: Although therapeutic choices for patients with chronic lymphocytic leukemia (CLL) were once limited, treatment of this disease has vastly improved in the last decades.Patients and methods: 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. Between 1983 and 1991, patients were give chlorambucil and prednisone (CP); after 1991 fludarabine and cyclophosphamide (FC) and after 1998, rituximab and FC (FCR).Results: 98 patients with CLL were identified; 49 were followed for >3 months. 21 persons (43%) did not require treatment nor progressed; 14 received CP, 6 FC, 7 FCR and one rituximab. Median overall survival (OS) has not been reached, being above 247 months; median OS for patients given CP was 115 months, for FC above 132 months and for FCR above 136 months (p > 0.5).Conclusion: CLL seems to be less aggressive in Mexican mestizos than in Caucasians; 43% of patients do not need treatment at all.

Treatment of Persons with Multiple Myeloma in Underprivileged Circumstances: Real-World Data from a Single Institution.

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. PATIENTS AND METHODS: All consecutive MM patients diagnosed in the Centro de Hematología y Medicina Interna de Puebla after 1993 were included in this study. Patients were given oral thalidomide (100 mg/day), oral dexamethasone (36-40 mg/week), and aspirin 100 mg/day. Bor-tezomib (1.75 mg s.c. every week) was administered to those who could afford it. After 4-6 weeks of treatment, patients were offered an outpatient-based hematopoietic cell transplant (HCT). After the recovery of granulocytes following HCT, patients continued indefinitely on thalidomide; those who failed to tolerate thalidomide were switched to lenalidomide (25 mg/day). RESULTS: The median overall survival (OS) for all patients has not been reached and is >157 months. Median follow-up of the patients lasted 14 months (range 1.3-157). The median OS of patients with and without HCT was similar. The response rate (complete remission or very good partial remission) was 72% for those given thalidomide plus dexamethasone versus 88% for those given bortezomib, thalidomide, and dexamethasone before HCT, but OS was not different. As post-HCT maintenance, 37 patients received thalidomide; 26 of those (70%) could be maintained indefinitely on thalidomide, whereas 11 were switched to lenalidomide after a median of 7 months; median OS of patients maintained on thalidomide or lenalidomide after HCT was not different. CONCLUSION: In this series, a regimen incorporating low-cost novel agents and outpatient HCT was associated with excellent long-term survival in the treatment of MM patients. This approach may be a model for MM treatment in underprivileged circumstances.
