International Society on Thrombosis and Haemostasis clinical practice guideline for treatment of congenital hemophilia A and B based on the Grading of Recommendations Assessment, Development, and Evaluation methodology.

BACKGROUND: Hemophilia is a rare congenital bleeding disorder that results from complete or partial deficiency of blood coagulation factor (F)VIII (hemophilia A) or FIX (hemophilia B) due to pathogenic variants in their coding genes. Hemophilia requires complex management. To date, there is no evidence-based clinical practice guideline on hemophilia treatment based on the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach. OBJECTIVES: This evidence-based clinical practice guideline from the International Society on Thrombosis and Haemostasis aims to provide an overview of evidence and support patients, caregivers, hematologists, pediatricians, other clinicians, researchers, and stakeholders in treatment decisions about congenital hemophilia A and B. METHODS: The International Society on Thrombosis and Haemostasis formed a multidisciplinary guideline panel of physicians and patients with global representation, balanced to minimize potential bias from conflicts of interest. The panel prioritized a set of clinical questions and outcomes according to their importance for clinicians and patients. A methodological team supported the guideline development process, including searching for evidence and performing systematic reviews. The GRADE approach was used, including GRADE Evidence to Decision frameworks. The recommendations were subject to public comment. RESULTS: The panel selected 13 questions, of which 11 addressed the treatment of hemophilia A and 2 the treatment of hemophilia B. Specifically, the panel addressed questions on prophylactic and episodic treatment with FVIII concentrates, bypassing agents, and nonfactor therapy (emicizumab) for hemophilia A (with and without inhibitors) as well as immune tolerance induction for hemophilia A. For hemophilia B, the panel addressed questions on prophylactic and episodic treatment of bleeding events with FIX concentrates. Agreement was reached for all 13 recommendations, of which 7 (54%) were based on evidence from randomized clinical trials, 3 (23%) on observational studies, and 3 (23%) on indirect comparisons. CONCLUSION: Strong recommendations were issued for prophylactic over episodic treatment for severe and moderately severe hemophilia A and B. Only conditional recommendations were issued for the remaining questions. Future research should focus on direct treatment comparisons and the treatment of hemophilia B with and without inhibitors. Future updates of this guideline will provide an updated evidence synthesis on the current questions and focus on new FVIII and FIX concentrates, novel nonfactor therapies, and gene therapy for severe and nonsevere hemophilia A and B.

Impact of a Regional Pediatric Hematology/Oncology Fellowship Program in Guatemala.

PURPOSE: This study aimed to describe and assess the regional experience of a pediatric hematology/oncology fellowship program based in Guatemala. METHODS: The Unidad Nacional de Oncología Pediátrica (UNOP) in Guatemala City, Guatemala, is the only hospital in Central America dedicated exclusively to childhood and adolescent cancer. To address the regional need for specialists, a fellowship program in pediatric hematology/oncology was launched in 2003. The UNOP fellowship program comprises 3 years of training. Although the program is based at UNOP, it also includes rotations locally and internationally to enhance clinical exposure. The curriculum is based on international standards to cover clinical expertise, research, professionalism, communication, and health advocacy. Trainees are selected according to country or facility-level need for pediatric hematologists/oncologists, with a plan for them to be hired immediately after completing their training. RESULTS: Forty physicians from 10 countries in Latin America have completed training. In addition, there are currently 13 fellows from five countries in training. Of the graduates, 39 (98%) are now practicing in pediatric hematology/oncology in Latin America. Moreover, many of them have leadership positions within their institutions and participate in research, advocacy, and policy making. Graduates from the UNOP program contribute to institutions by providing care for an increasing number of patients with pediatric cancer. The UNOP program is the first pediatric hematology/oncology fellowship program in the world to be accredited by Accreditation Council for Graduate Medical Education-International, an international body accrediting clinical training programs. CONCLUSION: The UNOP program has trained specialists to increase the available care for children with cancer in Latin America. This regional approach to specialist training can maximize resources and serve as a model for other programs and regions.

Enhancing diagnostic accuracy of multiple myeloma through ML-driven analysis of hematological slides: new dataset and identification model to support hematologists.

Multiple Myeloma (MM) is a hematological malignancy characterized by the clonal proliferation of plasma cells within the bone marrow. Diagnosing MM presents considerable challenges, involving the identification of plasma cells in cytology examinations on hematological slides. At present, this is still a time-consuming manual task and has high labor costs. These challenges have adverse implications, which rely heavily on medical professionals' expertise and experience. To tackle these challenges, we present an investigation using Artificial Intelligence, specifically a Machine Learning analysis of hematological slides with a Deep Neural Network (DNN), to support specialists during the process of diagnosing MM. In this sense, the contribution of this study is twofold: in addition to the trained model to diagnose MM, we also make available to the community a fully-curated hematological slide dataset with thousands of images of plasma cells. Taken together, the setup we established here is a framework that researchers and hospitals with limited resources can promptly use. Our contributions provide practical results that have been directly applied in the public health system in Brazil. Given the open-source nature of the project, we anticipate it will be used and extended to diagnose other malignancies.

Distinguishing ASH clinical practice guidelines from other forms of ASH clinical advice.

ABSTRACT: The American Society of Hematology (ASH) develops a variety of resources that provide guidance to clinicians on the diagnosis and management of blood diseases. These resources include clinical practice guidelines (CPGs) and other forms of clinical advice. Although both ASH CPGs and other forms of clinical advice provide recommendations, they differ with respect to the methods underpinning their development, the principal type of recommendations they offer, their transparency and concordance with published evidence, and the time and resources required for their development. It is crucial that end users be aware of the differences between CPGs and other forms of clinical advice and that producers and publishers of these resources use clear and unambiguous terminology to facilitate their distinction. The objective of this article is to highlight the similarities and differences between ASH CPGs and other forms of ASH clinical advice and discuss the implications of these differences for end users.

Variability in the perception of palliative care and end-of-life care among hematology professionals from the same reference center in Bahia, Brazil: A descriptive cross-sectional study.

BACKGROUND: There are several illness-specific cultural and system-based barriers to palliative care (PC) integration and end-of-life (EOL) care in the field of oncohematology. OBJECTIVES: This study aimed to investigate the variability in the perceptions of PC and EOL care. DESIGN AND SETTING: A cross-sectional study was conducted in the Hematology Division of our University Hospital in Salvador, Bahia, Brazil. METHODS: Twenty physicians responded to a sociodemographic questionnaire and an adaptation of clinical questionnaires used in previous studies from October to December 2022. RESULTS: The median age of the participants was 44 years, 80% of the participants identified as female, and 75% were hematologists. Participants faced a hypothetical scenario involving the treatment of a 65-year-old female with a poor prognosis acute myeloid leukemia refractory to first-line treatment. Sixty percent of the participants chose to follow other chemotherapy regimens, whereas 40% opted for PC. Next, participants considered case salvage for the patient who developed septic shock following chemotherapy and were prompted to choose their most probable conduct, and the conduct they thought would be better for the patient. Even though participants were from the same center, we found a divergence from the most probable conduct among 40% of the participants, which was due to personal convictions, legal aspects, and other physicians' reactions. CONCLUSIONS: We found considerable differences in the perception of PC and EOL care among professionals, despite following the same protocols. The study also demonstrated variations between healthcare professionals' beliefs and practices and persistent historical tendencies to prioritize aggressive interventions.

Hematology and Oncology Fellow Education About Sexual and Reproductive Health: A Survey of Program Directors in the United States.

PURPOSE: Clinical oncology guidelines recommend addressing sexual and reproductive health (SRH) concerns in routine cancer care. However, limited training often hinders clinicians' ability to do so effectively. The objective of this study was to understand the state of current fellowship education on SRH (ie, sexual health, safe sex practices, and fertility) through conducting a national survey of US hematology/oncology fellowship program directors (PDs). METHODS: A survey was sent to all PDs of adult hematology/oncology fellowship programs in the United States via online link. PDs who did not complete the survey were sent up to four follow-up emails and a paper mailing. Descriptive statistics and McNemar tests were conducted. RESULTS: One hundred-fourteen PDs responded (65%). Fewer programs offered formal instruction on sexual health (49%) and safe sex practices (37%) compared with fertility (75%). Informal training in SRH relied heavily on direct clinical experience (73%-78% of programs), with other methods (eg, case-based approaches, webinars, and journal clubs) being less common. Lack of experts to provide instruction was the most commonly cited barrier to offering training in SRH, endorsed by 74% for sexual health, 68% for safe sex practices, and 54% for fertility; difficulty finding space within the curriculum (50%; 54%; and 43%, respectively) and a lack of training requirements were also commonly endorsed (57%; 60%; and 35%, respectively). Barriers were endorsed more commonly for sexual health topics than fertility. CONCLUSION: The results highlight the scarcity of training in SRH, particularly in sexual health, within hematology/oncology fellowship programs. The heavy reliance on informal instruction methods may lead to inconsistent and inadequate education. Efforts to integrate comprehensive training in SRH into fellowship programs are crucial to ensuring that such concerns are included in routine cancer care.

Hematology and Serum Biochemistry of Coastal Seabirds Rehabilitated on the Southeastern and Southern Coast of Brazil.

Complete blood counts (n=566) and serum biochemistry (n=426) were assessed in seven coastal seabirds species that underwent rehabilitation along the southeastern and southern coast of Brazil from Saquarema, Rio de Janeiro State (22°56'16.44″S, 42°18'24.16″W) to Laguna, Santa Catarina State (28°29'43″S, 48°45'39.2″W), from August 2016 to August 2020. Blood samples were collected from four species of Charadriiformes, including Kelp Gull (Larus dominicanus, n=136), South American Tern (Sterna hirundinacea, n=25), Cabot's Tern (Thalasseus acuflavidus, n=17), and Common Tern (Sterna hirundo, n=14) as well as three species of Suliformes, the Brown Booby (Sula leucogaster, n=212), Magnificent Frigatebird (Fregata magnificens, n=104), and Neotropic Cormorant (Nannopterum brasilianum, n=58). The individuals were sampled as part of the protocol required before their release into the wild when considered healthy. This work aimed to establish the normal hematologic and biochemical reference values of those seabird species and, when possible, to analyze variations among age class and sex and to compare those with the available data in the literature. In addition, we provide the first baseline data for the South American Tern, Cabot's Tern, and Neotropic Cormorant. Baseline hematologic data are crucial for assessing health status of individuals and to support management and conservation actions, including release of seabirds into the wild.

Defining the Educational Needs for a Community-Based Hematology/Oncology Career: A National Needs Assessment.

PURPOSE: Little is known about the specific needs during training for hematology/oncology providers practicing in community-based settings. We conducted a national survey of hematologists/oncologists employed in community or academic-community hybrid settings to delineate their educational needs. METHODS: An electronic questionnaire was developed and distributed nationally through professional organizations. We primarily assessed whether survey participants received any specific training during fellowship for community-based practice. Participants were also surveyed regarding training experiences that might have affected their preparation. Relative risk (RR) and 95% CI were calculated using modified Poisson regression to identify factors associated with receiving training specifically for community-based settings. RESULTS: Of 125 participants from across 25 states, 63% were male and 58% identified as White. Less than half (41.6%, binomial 95% CI, 32.8 to 50.7) received any training in a community-based setting. Participants identified rotations in community settings (47%), direct mentorship from community-based physicians (40%), and longitudinal clinic in a community setting (36%) as experiences that would have been valuable. Specific curricula of interest included medical operations and administration (63%), health policy (35%), and quality improvement (27%). Respondents in clinical practice for <10 years were more likely to have received any training specifically for a community-based career (RR, 2.13 [95% CI, 1.18 to 3.86]). CONCLUSION: Our study demonstrates substantial unmet needs as they relate to deliberately training fellows destined for community-based careers. Prospective design of clinical training and curricula emphasizing longitudinal exposures to and key aspects of health care delivery in the community setting are paramount to achieving optimal goal-concordant hematology/oncology training during fellowship.

Haematology and biochemistry in healthy llamas at sea level.

In the last years, there has been an increasing interest in llamas, not only as part of a productive system, but mostly as companion animals. Most reports regarding clinical biochemistry and haematology include few llamas and details about their health status are not available. The present study aims to provide haematological and biochemical parameters for llamas of known health status. Twenty-three non-pregnant females and seven males that live in Buenos Aires, Argentina (34°36'S, 58°22'W, at sea level) were studied. Llamas were clinically healthy, in good nutritional status. Animals were kept at grass and were fed hay bale or pellets and water ad libitum. Blood samples were collected by jugular venipuncture in spring. Packed cell volume, leucocyte count, differential white cell count, platelets count, urea, creatinine, total proteins, albumin, alkaline phosphatase, aspartate aminotransferase, alanine aminotransferase, glucose, calcium and phosphate were assessed. No significant differences were observed between males and females, except for platelet count and calcium, which was greater in males (P˂0.01). Values obtained for the different parameters were similar to those previously reported, except for monocytes, alkaline phosphatase, glucose and calcium, that were lower and lymphocytes and platelets count, that were higher in this study. In conclusion, different ambient and methodological conditions might affect some parameters. The parameters hereby presented are representative of llama's population living at sea level in South America.

Consensus of the Brazilian association of hematology, hemotherapy and cellular therapy on patient blood management: Preoperative Clinical and Laboratory Assessment of the Patient

Abstract The preoperative clinical and laboratory evaluations of the patient is an essential step to ensure the safety and success of any surgical procedure. This assessment aims to identify any underlying medical conditions and risk factors and determine suitability for surgery. With this step, the medical team can adapt the care plan to meet each patient's specific needs, increasing the chances of a successful procedure. Good clinical assessment and comprehensive laboratory testing, when integrated into a Patient Blood Management approach, are invaluable in promoting safety of care, reducing transfusion risks, improving surgical outcomes, and optimizing resource utilization. This approach not only elevates the quality of care, but is also aligned with evidence-based practice and patient-centered principles, making it an essential component of the perioperative process.

A Doença Renal Crônica (DRC) é uma importante redução da função renal que causa alterações no metabolismo dos indivíduos. Para acompanhar a progressão da DRC e prevenir possíveis complicações, foi realizada uma pesquisa para avaliar o perfil sociodemográfico, bioquímico e hematológico de pacientes com Insuficiência Renal Crônica (IRC) submetidos a hemodiálise. Esta pesquisa foi quantitativa, descritiva e transversal de caráter retrospectivo, realizada por meio da análise de dados secundários contidos nos prontuários dos pacientes. A coleta de dados ocorreu no Centro de Hemodiálise da cidade de Russas, no Ceará. A amostra foi constituída por 161 pacientes com DRC, sendo 63,35% do sexo masculino e 85,71% pardos, com uma idade média de 54,39 anos. Desses, 63,97% tinham entre 2 e 10 anos de tratamento e 57,76% possuíam ensino fundamental incompleto. 19,25% residiam em Russas. Resultados: Após a hemodiálise, os resultados mostraram 44 mg/dL de Ureia, 48,44% dos pacientes com valores normais. A hemoglobina e hematócrito médios foram 11,8 g/dL e 33,7%, respectivamente, sendo que 63,35% tiveram valores reduzidos. 85,10% dos pacientes tiveram contagem de plaquetas normal, 72,04% níveis adequados de ferro e albumina, 52,79% tiveram níveis elevados de ferritina, 23,61% redução de transferrina e níveis lipídicos satisfatórios. 79,50% apresentaram níveis séricos de potássio dentro da normalidade, 12,42% de fósforo acima do normal, 85,09% de cálcio dentro dos valores normais, 39,13% de PTHi normais e 86,33% de glicose dentro dos valores considerados normais. Com base nos resultados, concluiu-se que todos os pacientes em tratamento hemodialítico apresentam diversas alterações em decorrência da DRC e do próprio processo de tratamento. Portanto, a realização de exames para avaliar ou monitorar possíveis complicações da IRC é essencial para criar estratégias e intervenções mais eficazes, que melhorem a assistência prestada a esses pacientes e, consequentemente, da qualidade e expectativa de vida dos mesmos.

Chronic Kidney Disease (CKD) is an important reduction in kidney function that causes changes in the metabolism of individuals. To monitor the progression of CKD and prevent possible complications, a survey was carried out to assess the sociodemographic, biochemical and hematological profile of patients with Chronic Renal Failure (CRF) undergoing hemodialysis. This research was quantitative, descriptive and cross-sectional with a retrospective character, carried out through the analysis of secondary data contained in the patients' medical records. Data collection took place at the Hemodialysis Center in the city of Russas, Ceará. The sample consisted of 161 patients with CKD, 63.35% male and 85.71% brown, with an average age of 54.39 years. Of these, 63.97% had between 2 and 10 years of treatment and 57.76% had incomplete primary education. 19.25% resided in Russas. Results: After hemodialysis, the results showed 44 mg/dL of Urea, 48.44% of patients with normal values. Average hemoglobin and hematocrit were 11.8 g/dL and 33.7%, respectively, with 63.35% having reduced values. 85.10% of the patients had normal platelet counts, 72.04% had adequate levels of iron and albumin, 52.79% had high levels of ferritin, 23.61% had reduced transferrin and satisfactory lipid levels. 79.50% had serum levels of potassium within the normal range, 12.42% of phosphorus above normal, 85.09% of calcium within normal values, 39.13% of PTHi normal and 86.33% of glucose within the values considered normal. Based on the results, it was concluded that all patients on hemodialysis have several changes due to CKD and the treatment process itself. Therefore, carrying out tests to assess or monitor possible complications of CRF is essential to create more effective strategies and interventions that improve the care provided to these patients and, consequently, their quality and life expectancy.

La Enfermedad Renal Crónica (ERC) es una reducción importante de la función renal que provoca cambios en el metabolismo de los individuos. Para monitorizar la evolución de la ERC y prevenir posibles complicaciones, se realizó una encuesta para evaluar el perfil sociodemográfico, bioquímico y hematológico de los pacientes con Insuficiencia Renal Crónica (IRC) en hemodiálisis. Esta investigación fue cuantitativa, descriptiva y transversal con carácter retrospectivo, realizada a través del análisis de datos secundarios contenidos en las historias clínicas de los pacientes. La recolección de datos ocurrió en el Centro de Hemodiálisis de la ciudad de Russas, Ceará. La muestra estuvo constituida por 161 pacientes con ERC, 63,35% del sexo masculino y 85,71% pardos, con una edad media de 54,39 años. De estos, 63,97% tenían entre 2 y 10 años de tratamiento y 57,76% tenían primaria incompleta. El 19,25% residía en Russas. Resultados: Posterior a la hemodiálisis los resultados arrojaron 44 mg/dL de Urea, 48,44% de los pacientes con valores normales. La hemoglobina y el hematocrito medios fueron 11,8 g/dl y 33,7 %, respectivamente, con un 63,35 % con valores reducidos. El 85,10% de los pacientes presentaba plaquetas normales, el 72,04% presentaba niveles adecuados de hierro y albúmina, el 52,79% presentaba niveles elevados de ferritina, el 23,61% presentaba transferrina reducida y niveles satisfactorios de lípidos. El 79,50% presentaba niveles séricos de potasio dentro de la normalidad, el 12,42% de fósforo por encima de lo normal, el 85,09% de calcio dentro de los valores normales, el 39,13% de PTHi normal y el 86,33% de glucosa dentro de los valores considerados normales. Con base en los resultados, se concluyó que todos los pacientes en hemodiálisis tienen varios cambios debido a la ERC y al propio proceso de tratamiento. Por tanto, la realización de pruebas para evaluar o monitorizar las posibles complicaciones de la IRC es fundamental para crear estrategias e intervenciones más eficaces que mejoren la atención a estos pacientes y, en consecuencia, su calidad y esperanza de vida.

[Update of triggers for detection of adverse drug events in hematologic patients]. / Atualização dos rastreadores para detecção de eventos adversos a medicamentos em pacientes hematológicos.

The use of triggers for the active search and detection of adverse drug events (ADEs) has been gaining ground within pharmacovigilance services. Thus, the main objective of the study was to propose a new list of triggers to be used in a center specialized in hematology in Rio de Janeiro, Brazil. The update of the list of triggers consisted of revising the current list, with the exclusion and inclusion of new triggers. To verify the performance of the new list of triggers, a cross-sectional study was conducted in which the new triggers were used to investigate the occurrence of ADEs in patients attended in the emergency unit or hospitalized from January to March 2022. For each suspected ADEs, the patient's profile and adverse drug reactions (ADRs) were characterized regarding causality and severity. The performance of the triggers and their ability to capture ADEs were estimated using the following indicators: frequency of the trigger per 100 medical records, frequency of ADEs per 100 records, and positive predictive value (PPV). To evaluate the overall performance of the proposed new list, the PPV was estimated. A total of 374 prescriptions for triggers were identified in 186 medical records. The most efficient in the detection of possible ADEs were: lidocaine, loperamide, bisacodyl, filgrastim and glycerin clyster. The overall PPV of the new suggested list was 48% versus 10% of the previous list. This study demonstrated the importance of an updated list of triggers for the monitoring of ADEs and improvement of the care provided.

A utilização de rastreadores para a busca ativa e detecção de eventos adversos a medicamentos (EAM) tem ganhado espaço nos serviços de farmacovigilância. Assim, o objetivo principal do estudo foi propor uma nova lista de rastreadores para ser empregada em um centro especializado em hematologia do Rio de Janeiro, Brasil. A atualização da lista de rastreadores consistiu na revisão da lista atual, com a exclusão e inclusão de rastreadores. Para verificar o desempenho da nova lista de rastreadores, realizou-se um estudo transversal em que os novos rastreadores foram utilizados para investigar a ocorrência de EAM em pacientes atendidos na emergência ou hospitalizados no período de janeiro a março de 2022. Para cada suspeita de EAM identificada, caracterizaram-se o perfil do paciente e as reações adversas a medicamentos (RAM) quanto à causalidade e gravidade. O desempenho dos rastreadores e sua capacidade de captação de EAM foram calculados por meio dos indicadores: frequência do rastreador por 100 prontuários, frequência de EAM por 100 prontuários e valor preditivo positivo (VPP). Para avaliar o desempenho global da nova lista proposta, calculou-se o VPP. Foram identificadas 374 prescrições de rastreadores em 186 prontuários. Os mais eficientes na detecção de possíveis EAM foram: lidocaína, loperamida, bisacodil, filgrastim e clister de glicerina. O VPP global da nova lista sugerida foi 48% contra 10% da lista anterior. Este estudo demonstrou a importância de uma lista de rastreadores atualizada para o monitoramento dos EAM e o aprimoramento da assistência prestada.

Este estudio demostró la importancia de una lista actualizada de rastreadores para monitorear EAM y mejorar la atención brindada.

Hematology and biochemistry parameters of the Central American bushmaster (Lachesis stenophrys) under human care in Costa Rica.

Background: The Central American bushmaster (Lachesis stenophrys) is one of the largest pitvipers in the Americas, with relatively low abundance, suspected population declines, and continuing loss, fragmentation, and habitat degradation. Aim: Conservation actions, both in the wild and in captivity, bear the need for health parameters that allow managers and veterinarians to have a better understanding of health, especially when there are relatively few individuals in captivity to obtain robust information since there is no published information on the genus. To have hematological and biochemical reference ranges on the genus Lachesis. Methods: Blood samples were collected from 32 individuals (18 females and 14 males) under human care from 7 zoological institutions from August 2022 to January 2023 and performed hematological and biochemical analyses. Results: Reference intervals of hematological analytes included packed cell volume (17.51%-37.27%), total red blood cell count (0.36-0.92 × 1012/l), hemoglobin (61.73-145.23 g/l), white blood cell count (3.18-13.79 × 109/l), lymphocytes (2.16%-11.23%), azurophils (0.50%-4.20%), monocytes (0.00%-0.21%), heterophils (0.05%-1.12%), eosinophils (0.00%-0.19%), basophils (0.00%-2.00%), and total thrombocyte count (0.68-6.68 × 109/l), and biochemistry reference intervals included total protein (41.76-111.31 g/l), albumin (11.46-28.69 g/l), globulins (29.25-85.14 g/l), aspartate aminotransferase (1.44-68.75 U/l), creatinine kinase (52.72-625.00 U/l), uric acid (20.02-438.53 µmol/l), glucose (0.68-3.29 mml/l), cholesterol (41.74-13.25 mmol/l), calcium (1.78-6.06 mmol/l), and phosphorus (0.72-2.26 mmol/l). Conclusion: This is the first report on the genus Lachesis reporting hematological and biochemical reference ranges.

Accuracy of HemoCue301 portable hemoglobin analyzer for anemia screening in capillary blood from women of reproductive age in a deprived region of Northern Peru: An on-field study.

OBJECTIVE: We aim to assess the accuracy and effectiveness of the HemoCue 301, a point-of-care (POC) device for measuring hemoglobin levels, and detecting anemia among individuals living in Tumbes, a rural, underserved area in Northern Peru. METHODS: Baseline analysis of a clinical trial aimed at assessing the effect of multi-fortified bread (NCT05103709). Adult women with capillary blood HemoCue 301 readings below 12 g/dL were recruited in coastal city of Tumbes, Peru. A total of 306 women took part of the study, venous blood samples were taken and analyzed with an automated hematology analyzer. Serum samples were used to measure ferritin, serum iron and C reactive protein. RESULTS: Capillary blood measured by the Hemocue 301 has a bias of 0.36 ± 0.93 g/dL respect to the automated Hb. More than 50% of women with normal ferritin values were classified as anemics according to the HemoCue 301. Automated Hb cut-off of 10.8 g/dL [AUC 0.82 (0.77-0.88)] had a specificity of 0.817 and a sensitivity 0.711 while with the HemoCue 301 cut-off of 11.1 g/dL [AUC 0.71 (0.62-0.79)] had a specificity of 0.697 and a sensitivity 0.688. The performance of the automated Hb cut-off was significantly better than the HemoCue (p<0.001). CONCLUSION: Caution must be taken when using POC devices, especially with values around the threshold. Cut-off values found in our study could be used as surrogate means when no confirmatory tests are available. Clinical outcomes should be prioritized when diagnosing iron deficiency anemia in women of reproductive age to ensure proper diagnosis.

The future of aplastic anemia treatment in Brazil: Lessons learned for global hematology.

Aplastic anemia (AA) is a rare serious hematologic disorder caused by hematopoietic stem cell failure in maintaining hematopoiesis. AA is virtually fatal if not treated, and diagnosis and therapy require extensive hematologic infrastructure. Academic medical centers in Brazil have continuously and significantly contributed to diagnostic tools and therapy development, from novel transplant strategies to drug combinations and implementation science in the national public health system. In the present review, we discuss how the collaborative effort among academic centers in hematology has contributed to improving health care for patients with aplastic anemia. We also discuss what needs are still unmet and how to overcome these challenges.

Hematology and blood biochemistry in a declining population of mantled howler monkeys (Alouatta palliata palliata) at La Pacifica, Costa Rica.

BACKGROUND: Alouatta palliata palliata are an ecologically flexible howler monkey subspecies that has recently been relisted as Endangered. Populations are declining through much of the subspecies' range, including at our study site at La Pacifica, Costa Rica. Our objectives were to screen blood hematology and biochemistry samples collected from this wild population to elucidate their baseline health. METHODS: We collected blood samples from 38 adult individuals from across the study site and analyzed 13 hematology and 14 biochemistry parameters. RESULTS: Most hematology and blood biochemistry parameter values were similar between males and females. However, mean hemoglobin was significantly lower, and mean white blood cell count was significantly higher in females; and mean calcium and mean creatinine were significantly lower in females compared to males. CONCLUSIONS: Overall, the La Pacifica population appeared healthy based on the blood parameters analyzed from sampled individuals. Our results were also largely consistent with published data available from other populations of A. p. palliata, and with reference values for captive Alouatta caraya.
