Abstract
INTRODUCTION The increase in the number of patients with hemoglobinopathies in Europe in recent decades highlights the need for more detailed epidemiological information in Spain. To fulfil this need, the Spanish Society of Pediatric Hematology and Oncology (SEHOP) sponsored the creation of a national registry of hemoglobinopathies known as REHem-AR (Spanish Registry of Hemoglobinopathies and Rare Anemias). Data from the transfusion-dependent (TDT) and non-transfusion-dependent (NTDT) β-thalassemia cohorts are described and analyzed. METHODS We performed an observational, multicenter, and ambispective study, which included patients of any age with TDT and NTDT, registered up to December 31, 2021. RESULTS Among the 1741 patients included, 168 cases of thalassemia were identified (103 TDT and 65 NTDT-patients). Survival at 18 years was 93% for TDT and 100% for NTDT. Regarding management, 80 patients with TDT (77.7%) and 23 patients with NTDT (35.4%) started chelation treatment during follow-up, with deferasirox being the most widely used. A total of 76 patients within the TDT cohort presented at least 1 complication (73.8%), the most frequent being hemosiderosis and osteopenia-osteoporosis. Comparison of both cohorts revealed significant differences in the diagnosis of hepatic hemosiderosis (p = 0.00024), although these were not observed in the case of cardiac iron overload (p = 0.27). DISCUSSION Our registry enabled us to describe the management of β thalassemia in Spain and to analyze the morbidity and mortality of the cohorts of patients with TDT and NTDT. Complications related to iron overload in TDT and NTDT account for most of the morbidity and mortality of the disease, which is associated with a considerable social, psychological, and economic impact, although cardiac, osteopathy and endocrinological complications requiring more attention. The convenience and simplicity of online registries make it possible to homogenize variables and periodically update data, thus providing valuable information on these diseases.

Abstract
PURPOSE Intraoperative cell salvage is central to Patient Blood Management including for lower segment caesarean section. Prior to April 2020, we initiated intraoperative cell salvage during caesarean section based on risk assessment for hemorrhage and patient factors. As the pandemic broadened, we mandated intraoperative cell salvage to prevent peri-partum anemia and potentially reduce blood product usage. We examined the association of routine intraoperative cell salvage on maternal outcomes. METHODS We conducted a single-center non-overlapping before-after study of obstetric patients undergoing lower segment caesarean section in the 2 months prior to a change in practice ('usual care = selective intraoperative cell salvage', n = 203) and the 2 months following ('mandated intraoperative cell salvage', n = 228). Recovered blood was processed when a minimal autologous reinfusion volume of 100 ml was expected. Post-operative iron infusion and length of stay were modelled using logistic or linear regression, using inverse probability weighting to account for confounding. RESULTS More emergency lower-segment caesarean sections occurred in the Usual Care group. Compared to the Usual Care group, post-operative hemoglobin was higher and anemia cases fewer in the Mandated intraoperative cell salvage group. Rates of post-partum iron infusion were significantly lower in the Mandated intraoperative cell salvage group (OR = 0.31, 95% CI = 0.12 to 0.80, P = 0.016). No difference was found for length of stay. CONCLUSION Routine cell salvage provision during lower segment caesarean section was associated with a significant reduction in post-partum iron infusions, increased post-operative hemoglobin and reduced anemia prevalence.

Factors affecting responsiveness of vadadustat in patients with anemia associated with chronic kidney disease: a post-hoc subgroup analysis of Japanese phase 3 randomized studies. Clin Exp Nephrol 2024; 28:391-403. [PMID: 38530490 PMCID: PMC11033221 DOI: 10.1007/s10157-023-02432-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/29/2023] [Accepted: 10/31/2023] [Indexed: 03/28/2024]
Abstract
BACKGROUND Vadadustat is an oral hypoxia-inducible factor prolyl hydroxylase inhibitor developed for treating anemia in chronic kidney disease (CKD). The purpose of this post-hoc analysis was to investigate the factors affecting the responsiveness to vadadustat in anemia patients with nondialysis-dependent (NDD) or hemodialysis-dependent (HDD) CKD in two Japanese phase 3 studies. METHODS Of 151 and 162 patients enrolled in NDD-CKD and HDD-CKD studies, 136 and 140 patients, respectively, were included and divided into subgroups for the analysis. To assess vadadustat responsiveness, the resistance index was defined as the mean body weight-adjusted dose of vadadustat (mg/kg) at weeks 20-24 divided by the mean hemoglobin (g/dL) at weeks 20-24. Multivariate analysis was performed to identify the variables affecting the resistance index. RESULTS Independent factors identified as determinants for better response to vadadustat were as follows: high baseline hemoglobin, low baseline eGFR, high week-20-24 ferritin, and CKD not caused by autoimmune disease/glomerulonephritis/vasculitis in NDD-CKD; and male sex, high baseline C-reactive protein, and low baseline erythropoiesis-stimulating agent resistance index (ERI) in HDD-CKD. CONCLUSIONS In this post-hoc analysis, several factors were identified as affecting the response to vadadustat. These results may provide useful information leading to an appropriate dose modification for vadadustat. CLINICAL TRIAL REGISTRATION NCT03329196 (MT-6548-J01) and NCT03439137 (MT-6548-J03).

Eur J Clin Pharmacol 2024; 80:759-770. [PMID: 38360988 DOI: 10.1007/s00228-024-03653-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/11/2023] [Accepted: 02/12/2024] [Indexed: 02/17/2024]
Abstract
OBJECTIVE This retrospective study aimed to investigate the potential impact of ticagrelor and clopidogrel treatment on cardiovascular outcomes in patients with anemia and acute coronary syndrome (ACS) and to provide insights into the optimal therapeutic approach for this vulnerable patient population. METHODS A retrospective research design was employed, involving patients diagnosed with ST-segment elevation myocardial infarction (STEMI) or non-ST-segment elevation myocardial infarction (NSTEMI) between 2014 and 2021. Inclusion criteria required a hemoglobin level below 12 mg/dL and a minimum 12-month P2Y12 inhibitor treatment. Comprehensive clinical, biochemical, and echocardiographic data were collected from the hospital's electronic repository. The primary efficacy endpoint was major adverse cardiovascular events (MACE), encompassing total mortality, cardiovascular mortality, reinfarction, ischemic stroke, and hemorrhagic stroke. Major hemorrhage was the primary safety endpoint. Secondary outcomes included total mortality, cardiovascular mortality, reinfarction, ischemic stroke, and hemorrhagic stroke, individually. RESULTS Patients treated with ticagrelor (n = 118) and clopidogrel (n = 538) were compared. No significant difference was observed in major adverse cardiovascular events (MACE) and major bleeding between ticagrelor and clopidogrel treatment groups (MACE: clopidogrel 10.0% vs. ticagrelor 11.0%, p = 0.75; major bleeding: clopidogrel 2.8%, ticagrelor 2.5%, p = 0.88). Patients with hemoglobin levels ≤ 8 mg/dL demonstrated significantly higher MACE and major bleeding rates in the ticagrelor group (p = 0.008 and p = 0.002, respectively). Among patients aged ≥ 75 years, ticagrelor treatment was associated with a higher risk of major bleeding (p = 0.04). CONCLUSIONS Ticagrelor and clopidogrel exhibited comparable efficacy and safety outcomes in anemic ACS patients over a one-year period. Although ticagrelor demonstrated superiority in reducing ischemic events, it is crucial to recognize the limitations of retrospective studies in informing clinical practice. This study offers valuable insights into tailoring antiplatelet therapy for anemic ACS patients and provides guidance for personalized treatment strategies, acknowledging the hypothesis-generating nature of retrospective analyses.

Abstract
INTRODUCTION Approximately 45% of patients with heart failure had iron deficiency for the rest of their lives. OBJECTIVE To determine the effect of iron treatment in patients with heart failure and iron deficiency or anemia. MATERIALS AND METHODS The studies were selected in: PubMed, Scopus, Cochrane and Google Scholar, from the beginning of June to July 2023. The selected articles that met the inclusion criteria, the relevant information of the studies were collected according to the selection variables and were recorded in the Revman 5.0 program of the Cochrane collaboration. The primary outcome was composed of hospitalization for heart failure or cardiovascular death. RESULTS Of the 7 included studies, 6717 patients were obtained, the average age was 70 years with a predominance of the male gender (57%). The primary outcome was lower in patients in the control group compared to the placebo group (OR, 0.62; 95%CI, 0.54-0.70). The 6-minute walk test (6-MWT) was improved in the iron-supplemented group compared to the placebo group (OR, 0.79; 95%CI, 0.64-0.98). Adverse events were fewer in the iron supplement group compared to the placebo group (OR, 0.78; 95%CI, 0.67-0.91). CONCLUSION In this meta-analysis of randomized controlled trials, the effect of iron supplementation is found to reduce the incidence rate of hospitalization for heart failure or cardiovascular death. In addition to a reduction in adverse events, such as gastrointestinal and neurological disorders, it also improves 6-MWT.

Abstract
BACKGROUND For anemia management in patients with chronic kidney disease not on dialysis, darbepoetin alfa (DA), which has a shorter half-life but is more inexpensive than continuous erythropoietin receptor activator (CERA), is preferred in Korea. This study evaluated the efficacy, safety, and cost-effectiveness of once-in-4-weeks DA compared with once-in-4-weeks CERA in patients with chronic kidney disease not on dialysis. METHODS In this randomized, prospective, non-inferiority study, 40 erythropoiesis-stimulating agent-naïve patients with chronic kidney disease not on dialysis were randomized 1:1 to the DA group and CERA group. They received the study drug once in 4 weeks during 10- or 12-week correction period and 24-week efficacy evaluation period. The primary outcomes were the mean difference in the changes in hemoglobin levels between baseline and efficacy evaluation period and hemoglobin response rates during the correction period. The secondary outcomes included differences in adverse events and costs. RESULTS DA was non-inferior to CERA for anemia correction; the mean difference in the change in hemoglobin levels between the groups was -0.070 g/dL (95% confidence interval, -0.730 to 0.590 g/dL). Hemoglobin response rates were 100% with DA and 94.1% with CERA. Adverse events were comparable. The mean cost of DA was approximately one-third that of CERA (34,100 ± 7,600 Korean won/4 weeks vs. 115,500 ± 23,600 Korean won/4 weeks; p < 0.001). CONCLUSION Once-in-4-weeks DA safely corrects anemia in erythropoiesis-stimulating agent-naïve patients with chronic kidney disease not on dialysis and is more cost-effective than once-in-4-weeks CERA.

Abstract
Daily administration of oral iron is considered the current treatment standard for treating iron deficiency anemia due to availability and reduced cost compared to intravenous iron therapy. But adverse effects like epigastric pain, heartburn, and constipation reduce compliance to daily oral iron. There is scanty evidence regarding compliance and efficacy with alternate-day iron therapy. As per our knowledge, this is the first systematic review to compare daily with alternate-day oral iron therapy. Six electronic databases including PubMed and EMBASE were searched for randomized controlled trials, quasi-experimental studies published between January 2000 to March 2023 that compared daily with alternate day iron therapy in individuals diagnosed with iron deficiency anemia. The primary outcome analyzed was a change in hemoglobin. The other hematological parameters were assessed as secondary outcomes. Risk of bias was assessed regarding randomization process, deviation from intended intervention, missing outcome data, measurement of the outcome, and selection of the reported result. Out of the 9 full-text articles, 2 were not included as one was an ongoing trial and the second one had a different study design. The reviewed trials involved 594 participants, and the study participants ranged from 19 to 200. The mean age of the participants in the reported trials was 21 ± 2 to 49 ± 16 years. There is no significant increase in hemoglobin level and also the iron indices namely ferritin, hepcidin, total iron binding capacity, and reticulocyte count between daily and alternate-day dosing of iron. However, the frequency of adverse effects especially nausea, metallic taste, and altered bowel habits are reduced with alternate-day dosing. Oral iron given daily or on alternate days did not have a significant difference in the hemoglobin levels though iron absorption may be affected in the initial few days.Trial registration: The review protocol was registered with PROSPERO (Prospero2023CRD42023393095).

Abstract
PURPOSE Anemia has been shown to be a modifiable pre-operative, patient factor associated with outcome following arthroplasty. The aims of this retrospective study were to (1) ascertain the prevalence of preoperative anemia in patients undergoing primary and revision hip and knee arthroplasty at a tertiary referral center and (2) to test the association with outcome and whether it differs between primary and revision cases. METHODS All hip and knee primary and revision arthroplasties performed at a Canadian academic, tertiary-care, arthroplasty center between 2012 and 2017 were included in this study. The study group consisted of 5944 patients, of which 5251 were primary Total Hip and Knee Arthroplasties or Hip Resurfacings and 693 were revision arthroplasties (65% hip revisions/35% knee revisions). Anemia was classified as per WHO definition (hemoglobin < 130 g/L for men and < 120 g/L for women). All anemic patients were grouped into mild, moderate or severe anemia. Length-of-stay, perioperative transfusion-rate, 90-day readmission, overall complication rate and reoperation rates were recorded. The effect of preoperative anemia and the effect of severity of the anemia was evaluated through multivariable regression analysis controlling for relevant covariates. RESULTS Preoperatively, 15% (786/5251) of the primary patients and 47% (322/693) of the revision arthroplasty patients were anemic preoperatively. Anemic revision patients were 3.1 times more likely (95% CI: 1.47-6.33) to obtain blood transfusions during the hospital stay, compared to a 4.9 times higher risk in primary patients. The odds ratio to sustain any postoperative complication if anemic was 1.5 times higher (95% CI: 0.73-3.16) in revision patients and 1.7 in primary cases. In addition, the 90-day readmission rate among both groups was 1.6 times higher in anemic patients. Furthermore, anemic revision patients had a 5.3 days longer length of stay (95% CI: 2.63-7.91), compared to only 1 additional day in anemic primary patients (95% CI: 0.69-1.34). CONCLUSION In this study cohort, the prevalence of anemia in patients awaiting revision arthroplasty was 3 times higher (46.6%) than in primary arthroplasty patients (18.7%). Preoperative anemia was associated with similarly, inferior outcomes in both groups. To reduce postoperative complications and the "burden" associated with anemia, these findings strongly recommend optimizing the preoperative hemoglobin in all arthroplasty patients. However, revision patients are affected more frequently, and particular attention must therefore be taken to this growing group in the future. LEVEL OF EVIDENCE Level III.

Abstract
BACKGROUND Most cardiac surgery patients experience postoperative anemia. Delirium and Atrial Fibrillation (AF) are common and independent predictors of morbidity and mortality. Few reports examine their association with postoperative anemia. This study aims to quantify the association between anemia and these outcomes in patients undergoing cardiac surgery. METHODS This post-hoc analysis of the DECADE randomized controlled trial ran at six academic US hospitals. Patients aged 18-85 years with heart rate > 50 bpm undergoing cardiac surgery who had daily hemoglobin measurements in the first 5 Postoperative Days (POD) were included. Delirium was assessed twice daily with the Confusion Assessment Method for the ICU (CAM - ICU), preceded by the Richmond Agitation and Sedation Scale, with patients excluded from assessment if sedated. Patients had daily hemoglobin measurements, continuous cardiac monitoring plus twice-daily 12-lead electrocardiograms, up to POD4. AF was diagnosed by clinicians blinded to hemoglobin levels. RESULTS Five hundred and eighty-five patients were included. Mean postoperative hemoglobin Hazard Ratio (HR): 0.99 (95% CI 0.83, 1.19; p = 0.94) per 1 g.dL-1 hemoglobin decrease. 197 (34%) developed AF, mainly on POD = 2.3. Estimated HR = 1.04 (95% CI 0.93, 1.17; p = 0.51) per 1 g.dL-1 hemoglobin decrease. CONCLUSIONS Most patients undergoing major cardiac surgery were anemic in the postoperative phase. AF and delirium occurred in 34% and 12% of patients, respectively, but neither were significantly correlated with postoperative hemoglobin.

Abstract
Subnormal levels of liver enzymes, below the lower limit of normal on local laboratory reports, can be useful diagnostically. For instance, subnormal levels of aminotransferases can be observed in vitamin B6 deficiency and chronic kidney disease. Subnormal alkaline phosphatase levels may indicate the presence of hypophosphatasia, Wilson's disease, deficiencies of divalent ions, or malnutrition. Subnormal levels of gamma glutamyl transferase may be seen in cases of acute intrahepatic cholestasis, the use of certain medications, and in bone disease. Finally, subnormal levels of 5'-nucleotidase have been reported in lead poisoning and nonspherocytic hemolytic anemia. The aim of this review is to bring attention to the fact that subnormal levels of these enzymes should not be ignored as they may indicate pathological conditions and provide a means of early diagnosis.

Abstract
The primary triggers that stimulate the body to generate platelet antibodies via immune mechanisms encompass events such as pregnancy, transplantation, and blood transfusion. Interestingly, our findings revealed that a subset of male patients with hepatocellular carcinoma (HCC), despite having no history of transplantation or blood transfusion, has shown positive results in platelet antibody screenings. This hints at the possibility that certain factors, potentially related to the tumor itself or its treatment, may affect antibody production. To delve the causes we initiated this study. We employed a case-control study approach to analyze potential influential factors leading to the positive results via univariate and multivariate regression analysis. We utilized Kendall's tau-b correlation to examine the relationship between the strength of platelet antibodies and peripheral blood cytopenia. Antitumor medication emerged as an independent risk factor for positive results in HCC patients, and the strength of platelet antibodies positively correlated with the severity of anemia and thrombocytopenia. Without history of blood transfusion, transplantation, pregnancy, those HCC patients underwent recent tumor medication therapy are experiencing peripheral erythrocytopenia or thrombocytopenia, for them platelet antibody screenings holds potential clinical value for prevention and treatment of complications like drug-immune-related anemia and/or bleeding.

Abstract
BACKGROUND Postpartum anemia, characterized by hematocrit or hemoglobin levels below the defined cutoff point (< 11gm/dl or hematocrit < 33%), is a prevalent global issue. It serves as an indirect contributor to maternal mortality and morbidity. Mothers in the postpartum period experience diminished quality of life, impaired cognitive function, emotional instability, and an increased risk of postpartum depression due to anemia. Additionally, infants of affected mothers may face challenges such as insufficient breast milk supply and a lack of proper care. Examining the combined prevalence and factors associated with postpartum anemia is crucial for addressing maternal health risks and complications during the postnatal phase attributed to anemia. OBJECTIVE The study aimed to synthesize the existing literature on the prevalence and associated factors of postpartum anemia in public health facilities of Ethiopia, in 2024. METHODS The study was conducted by searching through the Google Scholar, PubMed, and Cochrane Library search engines. The search utilized keywords and MeSH terms such as anemia, low hemoglobin, postpartum, postnatal women, and Ethiopia. The collected data underwent analysis and comparison with the WHO criteria to determine if it met the threshold for declaring a public health concern. Heterogeneity was evaluated through the Cochran Q test and I2 statistics. Prevalence and odds ratio estimations were performed using a random-effects model with a 95% confidence interval. RESULT Four studies were included in this systematic review and meta-analysis. The overall pooled prevalence of anemia among postpartum women in Ethiopia was 69% (95% CI: 60- 77%).Lack of formal education(OR = 3.5;CI:2.639,4.408),Low Pre-delivery hemoglobin (OR = 4.2;CI: 1.768-6.668), Postpartum women < 4 ANC visit (OR = 2.72; 95% CI:2.14,3.3 ),history of post partum hemorrhage (OR = 2.49; CI: 1.075-3.978),history of Forceps/vacuum delivery(OR = 3.96; CI:2.986-4.947), Poor iron and folic acid adherence (OR = 2.8;95% CI:2.311,3.297), C/S (OR = 4.04; 95% CI: 3.426,4.671),lower dietary diversity (OR = 4.295% CI:1.768,6.668) were significantly associated postpartum anemia. CONCLUSION Postpartum women in Ethiopia continue to face a considerable public health challenge in the form of anemia. Consequently, there is a pressing need for the government to formulate comprehensive, multi-sectorial policies and strategies. These initiatives should be designed to address the substantial regional disparities influenced by interconnected factors, with the aim of reducing the prevalence of anemia among postpartum women in Ethiopia.

BMC Pregnancy Childbirth 2024; 24:317. [PMID: 38664625 PMCID: PMC11044590 DOI: 10.1186/s12884-024-06495-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/23/2024] [Accepted: 04/09/2024] [Indexed: 04/29/2024] Open
Abstract
BACKGROUND The immediate postpartum period is a very crucial phase for both the life of the mother and her newborn baby. Anemia is the most indirect leading cause of maternal mortality. However, anemia in the immediate postpartum period is a neglected public health problem in Ethiopia. Therefore, this systematic review and meta-analysis aimed to estimate the pooled magnitude of immediate postpartum anemia and the pooled effect size of associated factors in Ethiopia. METHODS Searching of published studies done through PubMed, Medline, Cochrane, African index Medicus, List of Reference Index, Hinari, and Google Scholar. This systematic review and meta-analysis follow the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) godliness. The quality of studies was assessed by using a Newcastle- Ottawa Scale (NOS) assessment tool. Analysis was performed using a random effect model by using STATA 17 version software. Egger's weighted regression and I2 test were used to evaluate publication bias and heterogeneity respectively. RESULTS In this systematic review and meta-analysis, a total of 6 studies were included. The pooled magnitude of immediate postpartum anemia in Ethiopia was 27% (95%CI: 22, 32). Instrumental mode of delivery (OR = 3.14, 95%CI: 2.03, 4.24), mid-upper arm circumference (MUAC) measurement < 23 cm (OR = 3.19, 95%CI: 1.35, 5.03), Antepartum Hemorrhage (OR = 4.75, 95%CI: 2.46, 7.03), postpartum hemorrhage (OR = 4.67, 95%CI: 2.80, 6.55), and no iron/foliate supplementation (OR = 2.72, 95%CI: 1.85, 3.60) were the identified factors associated with developing anemia in the immediate postpartum period. CONCLUSION The overall pooled magnitude of anemia in the immediate postpartum period among Ethiopian women was still a moderate public health problem. Instrumental mode of delivery, mid upper arm circumference (MUAC) measurement < 23 cm, antepartum hemorrhage, postpartum hemorrhage, and no iron/foliate supplementation were the identified factors associated with higher odds of developing anemia among immediate postpartum women in Ethiopia. Therefore, midwives, and doctors, shall focus on prevention of maternal hemorrhage, nutritional advice and counseling including iron /foliate supplementation, and avoid unnecessary instrumental delivery to prevent and reduce anemia related maternal mortality and morbidity in Ethiopia.

Abstract
OBJECTIVES This study aimed to examine the relationship between anemia and all-cause mortality in Chinese centenarians. DESIGN Prospective cohort study. SETTING AND PARTICIPANTS We included 1002 Chinese centenarians from the China Hainan Centenarian Cohort Study (CHCCS) MEASUREMENTS: Standard procedures were followed to perform blood analysis, home interviews, and physical examinations. Anemia was defined as a hemoglobin level of less than 130 g/L for men and less than 120 g/L for women. RESULTS During the 9-year follow-up period, a total of 929 (92.7%) deaths were identified. Cox proportional hazards regression models revealed that anemia (hazard ratio [HR] 1.289, 95% confidence interval [CI]: 1.117-1.489) was significantly associated with all-cause mortality. There was an apparent dose-response relationship between anemia and all-cause mortality. Centenarians with severe anemia had approximately 1.6 times higher likelihood of all-cause mortality than those without anemia (HR 1.662; 95% CI: 1.154-2.394). CONCLUSION Anemia is associated with an increased risk of all-cause mortality in Chinese centenarians. Further research will be needed to collect more comprehensive data on the etiology of anemia and causes of death in centenarians.

Abstract
OBJECTIVES To investigate the association between baseline hemoglobin level and early neurologic deterioration (END) after intravenous thrombolysis in patients with acute ischemic stroke (AIS). METHODS Data of AIS patients who received intravenous thrombolytic therapy at multiple hospitals across the country between January 2017 and July 2020 were collected from the online database Acute Stroke Patients for Stroke Management Quality Evaluation (CASE-Ⅱ, NCT04487340). Binary logistic regression analysis was used to study the factors affecting the occurrence of END after intravenous thrombolytic therapy, and the correlation between baseline hemoglobin level and END was investigated by limiting cubic spline curve analysis. RESULTS A total of 8162 patients were included. Patients with END had lower baseline hemoglobin levels (136 and 140 g/L, P<0.01) and higher rates of anemia (24.2% and 16.9%, P<0.01) compared with non-END patients. Binary logistic regression analysis showed that baseline hemoglobin level (OR=0.995, 95%CI: 0.991-0.999, P<0.05) and anemia (OR=1.238, 95%CI: 1.055-1.454, P<0.01) were independently correlated with the occurrence of END after intravenous thrombolysis in AIS patients. Restricted cubic spline regression showed that there was a U-shaped relationship between hemoglobin level and the risk of END after intravenous thrombolysis in AIS patients (P<0.01), although this relationship was only significant in male patients (P<0.05) and not in female patients (P>0.05). CONCLUSIONS There is a correlation between baseline hemoglobin level and the risk of END in AIS patients after intravenous thrombolysis, especially in male patients, in whom both lower and higher hemoglobin level may increase the risk of END.

Abstract
INTRODUCTION Preoperative anemia affects approximately one third of surgical patients. It increases the risk of blood transfusion and influences short- and medium-term functional outcomes, increases comorbidities, complications and costs. The "Patient Blood Management" (PBM) programs, for integrated and multidisciplinary management of patients, are considered as paradigms of quality care and have as one of the fundamental objectives to correct perioperative anemia. PBM has been incorporated into the schemes for intensified recovery of surgical patients: the recent Enhanced Recovery After Surgery 2021 pathway (in Spanish RICA 2021) includes almost 30 indirect recommendations for PBM. OBJECTIVE To make a consensus document with RAND/UCLA Delphi methodology to increase the penetration and priority of the RICA 2021 recommendations on PBM in daily clinical practice. MATERIAL AND METHODS A coordinating group composed of 6 specialists from Hematology-Hemotherapy, Anesthesiology and Internal Medicine with expertise in anemia and PBM was formed. A survey was elaborated using Delphi RAND/UCLA methodology to reach a consensus on the key areas and priority professional actions to be developed at the present time to improve the management of perioperative anemia. The survey questions were extracted from the PBM recommendations contained in the RICA 2021 pathway. The development of the electronic survey (Google Platform) and the management of the responses was the responsibility of an expert in quality of care and clinical safety. Participants were selected by invitation from speakers at AWGE-GIEMSA scientific meetings and national representatives of PBM-related working groups (Seville Document, SEDAR HTF section and RICA 2021 pathway participants). In the first round of the survey, the anonymized online questionnaire had 28 questions: 20 of them were about PBM concepts included in ERAS guidelines (2 about general PBM organization, 10 on diagnosis and treatment of preoperative anemia, 3 on management of postoperative anemia, 5 on transfusion criteria) and 8 on pending aspects of research. Responses were organized according to a 10-point Likter scale (0: strongly disagree to 10: strongly agree). Any additional contributions that the participants considered appropriate were allowed. They were considered consensual because all the questions obtained an average score of more than 9 points, except one (question 14). The second round of the survey consisted of 37 questions, resulting from the reformulation of the questions of the first round and the incorporation of the participants' comments. It consisted of 2 questions about general organization of PBM programme, 15 questions on the diagnosis and treatment of preoperative anemia; 3 on the management of postoperative anemia, 6 on transfusional criteria and finally 11 questions on aspects pending od future investigations. Statistical treatment: tabulation of mean, median and interquartiles 25-75 of the value of each survey question (Tables 1, 2 and 3). RESULTS Except for one, all the recommendations were accepted. Except for three, all above 8, and most with an average score of 9 or higher. They are grouped into: 1.- "It is important and necessary to detect and etiologically diagnose any preoperative anemia state in ALL patients who are candidates for surgical procedures with potential bleeding risk, including pregnant patients". 2.- "The preoperative treatment of anemia should be initiated sufficiently in advance and with all the necessary hematinic contributions to correct this condition". 3.- "There is NO justification for transfusing any unit of packed red blood cells preoperatively in stable patients with moderate anemia Hb 8-10g/dL who are candidates for potentially bleeding surgery that cannot be delayed." 4.- "It is recommended to universalize restrictive criteria for red blood cell transfusion in surgical and obstetric patients." 5.- "Postoperative anemia should be treated to improve postoperative results and accelerate postoperative recovery in the short and medium term". CONCLUSIONS There was a large consensus, with maximum acceptance,strong level of evidence and high recommendation in most of the questions asked. Our work helps to identify initiatives and performances who can be suitables for the implementation of PBM programs at each hospital and for all patients.

Abstract
OBJECTIVE To assess the prevalence of anemia among pregnant women across their entire pregnancy and the factors affecting it in the monitoring areas. METHODS A total of 108,351 pregnant women who received antenatal health care and delivered from January 1, 2016 to December 31, 2020 in 15 monitoring counties of 8 provinces in the Maternal and Newborn Health Monitoring Program (MNHMP) of National Center for Women and Children's Health (NCWCH) were selected as the study subjects. The anemia status among the subjects across their first, second and third trimester of pregnancy and the influencing factors were analyzed. RESULTS From 2016 to 2020, the prevalence of anemia at any stage during pregnancy in the monitoring areas was 43.59%. The prevalence of anemia among pregnant women across all three trimesters was 3.95%, and the prevalence of mild and moderate-to-severe anemia was 1.04% and 2.90%, respectively. Protective factors were living in the northern area (OR = 0.395) and being a member of an ethnic minority (OR = 0.632). The risk factors were residing in rural areas (OR = 1.207), with no more than junior high school education (OR = 1.203), having ≥ 3 gravidities (OR = 1.195) and multiple fetuses (OR = 1.478). CONCLUSIONS Although the prevalence of anemia among pregnant women across all trimesters in the monitoring area was low, the severity of anemia was high. Since the prevalence of anemia among pregnant women across their entire pregnancy in the monitoring area is affected by many different factors, more attention should be paid to pregnant women living in rural areas, with low literacy, ≥ 3 gravidities and multiple fetuses for early intervention.

Abstract
PURPOSE Preoperative anemia increases postoperative morbidity, mortality, and the risk of allogeneic transfusion. However, the incidence of preoperative anemia in patients undergoing total hip arthroplasty and total knee arthroplasty (TKA) and its relationship to postoperative outcomes has not been previously reported. METHODS We conducted a comprehensive literature search through PubMed, Cochrane Library, Web of Sincien, and Embase from inception to July 2023 to investigate the prevalence of preoperative anemia in patients undergoing Total Joint Arthroplasty, comorbidities between anemic and non-anemicpatients before surgery, and postoperative outcomes. postoperative outcomes were analyzed. Overall prevalence was calculated using a random-effects model, and heterogeneity between studies was examined by Cochran's Q test and quantified by the I2 statistic. Subgroup analyses and meta-regression analyses were performed to identify sources of heterogeneity. Publication bias was assessed by funnel plots and validated by Egger's test. RESULTS A total of 21 studies with 369,101 samples were included, all of which were retrospective cohort studies. 3 studies were of high quality and 18 studies were of moderate quality. The results showed that the prevalence of preoperative anemia was 22% in patients awaiting arthroplasty; subgroup analyses revealed that the prevalence of preoperative anemia was highest in patients awaiting revision of total knee arthroplasty; the highest prevalence of preoperative anemia was found in the Americas; preoperative anemia was more prevalent in the female than in the male population; and preoperative anemia with a history of preoperative anemia was more common in the female than in the male population. patients with a history of preoperative anemia; patients with joint replacement who had a history of preoperative anemia had an increased risk of infection, postoperative blood transfusion rate, postoperative blood transfusion, Deep vein thrombosis of the lower limbs, days in hospital, readmission within three months, and mortality compared with patients who did not have preoperative anemia. CONCLUSION The prevalence of preoperative anemia in patients awaiting total joint arthroplasty is 22%, and is higher in TKA and female patients undergoing revision, while preoperative anemia is detrimental to the patient's postoperative recovery and will increase the risk of postoperative complications, transfusion rates, days in the hospital, readmission rates, and mortality.

Abstract
Recessive dystrophic epidermolysis bullosa (RDEB) is a rare genetic disease resulting from inadequate type VII collagen (C7). Although recurrent skin blisters and wounds are the most apparent disease features, the impact of C7 loss is not confined to the skin and mucous membranes. RDEB is a systemic disease marred by chronic inflammation, fibrotic changes, pain, itch, and anemia, significantly impacting QOL and survival. In this narrative review, we summarize these systemic features of RDEB and promising research avenues to address them.

INTERNATIONAL JOURNAL OF BIOMETEOROLOGY 2024:10.1007/s00484-024-02670-0. [PMID: 38607561 DOI: 10.1007/s00484-024-02670-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/01/2024] [Revised: 02/01/2024] [Accepted: 04/01/2024] [Indexed: 04/13/2024]
Abstract
Previous studies have suggested that exposure to air pollutants may be associated with specific blood indicators or anemia in certain populations. However, there is insufficient epidemiological data and prospective evidence to evaluate the relationship between environmental air pollution and specific types of anemia. We conducted a large-scale prospective cohort study based on the UK Biobank. Annual average concentrations of NO2, PM2.5, PM2.5-10, and PM10 were obtained from the ESCAPE study using the Land Use Regression (LUR) model. The association between atmospheric pollutants and different types of anemia was investigated using the Cox proportional hazards model. Furthermore, restricted cubic splines were used to explore exposure-response relationships for positive associations, followed by stratification and effect modification analyses by gender and age. After adjusting for demographic characteristics, 3-4 of the four types of air pollution were significantly associated with an increased risk of iron deficiency, vitamin B12 deficiency and folate deficiency anemia, while there was no significant association with other defined types of anemia. After full adjustment, we estimated that the hazard ratios (HRs) of iron deficiency anemia associated with each 10 μg/m3 increase in NO2, PM2.5, and PM10 were 1.04 (95%CI: 1.02, 1.07), 2.00 (95%CI: 1.71, 2.33), and 1.10 (95%CI: 1.02, 1.20) respectively. The HRs of folate deficiency anemia with each 10 μg/m3 increase in NO2, PM2.5, PM2.5-10, and PM10 were 1.25 (95%CI: 1.12, 1.40), 4.61 (95%CI: 2.03, 10.47), 2.81 (95%CI: 1.11, 7.08), and 1.99 (95%CI: 1.25, 3.15) respectively. For vitamin B12 deficiency anemia, no significant association with atmospheric pollution was found. Additionally, we estimated almost linear exposure-response curves between air pollution and anemia, and interaction analyses suggested that gender and age did not modify the association between air pollution and anemia. Our research provided reliable evidence for the association between long-term exposure to PM10, PM2.5, PM2.5-10, NO2, and several types of anemia. NO2, PM2.5, and PM10 significantly increased the risk of iron deficiency anemia and folate deficiency anemia. Additionally, we found that the smaller the PM diameter, the higher the risk, and folate deficiency anemia was more susceptible to air pollution than iron deficiency anemia. No association was observed between the four types of air pollution and hemolytic anemia, aplastic anemia, and other types of anemia. Although the mechanisms are not well understood, we emphasize the need to limit the levels of PM and NO2 in the environment to reduce the potential impact of air pollution on folate and iron deficiency anemia.

Abstract
BACKGROUND Sickle cell disease (SCD) is one of the most frequent inherited diseases in the world. Over the last decades, in high-income countries, an important decrease in mortality have been observed due to the improvement of care. However, children with SCD can become critically ill and require admission in Pediatric Intensive Care Units (PICU). The purpose of this study was to describe the epidemiology of children with SCD admitted to PICU for acute crisis and to identify factors associated with adverse outcome (AO). METHODS We conducted a retrospective study in a Tertiary Hospital in France including all consecutive children with SCD admitted to PICU between January 1st, 2009 and December 31, 2019. We collected baseline patient's characteristics, clinical and biological data as well as treatments and life sustaining therapies used in the PICU. Patients were defined as experiencing AO in case of death during stay and/or need for invasive mechanical ventilation (MV) and/or for non-invasive ventilation (NIV) for more than 3 days and/or need for vasopressors and/or need for renal replacement therapy. RESULTS We included 579 admissions in 395 patients, mainly of SS genotype (90%) with a median age of 9.2 years [5.5-13.4] and a median baseline hemoglobin of 8.0 g/dl (7.5-8.8). The two main reasons for admission were acute chest syndrome (ACS) (n = 331, 57%) and vaso-occlusive crisis refractory to first line therapy (n = 99, 17%). Half of patients required NIV and 47 (8%) required MV. The overall length of stay was 3 days [1-4] and seven (1%) patients died during PICU stay.There was a total of 113 (20%) admissions with AO and on multivariable analysis, baseline hemoglobin < 8 g/dL, history of bronchial obstruction and admission for ACS were associated with AO. There was no difference in the proportion of hydroxyurea treatment or exchange transfusion program between patients with AO and the other patients. CONCLUSIONS Baseline hemoglobin < 8 g/dL, history of bronchial obstruction and admission for ACS were the strongest risk factors for severe evolution in SCD children admitted to PICU. These factors could be taken into consideration when choosing the adequate therapeutic options.

Abstract
BACKGROUND Anemia is a hallmark of critical illness, which is largely inflammatory driven. We hypothesized that the use of anti-inflammatory agents limits the development of anemia and reduces the need for red blood cell (RBC) transfusions in patients with a hyper-inflammatory condition due to COVID-19. METHODS An observational cohort (n = 772) and a validation cohort (a subset of REMAP-CAP, n = 119) of critically ill patients with hypoxemic respiratory failure due to COVID-19 were analyzed, who either received no treatment, received steroids or received steroids plus IL-6 blocking agents. The trajectory of hemoglobin (Hb) decline and the need for RBC transfusions were compared using descriptive statistics as well as multivariate modeling. RESULTS In both cohorts, Hb level was higher in the treated groups compared to the untreated group at all time points. In the observational cohort, incidence and number of transfused patients were lower in the group receiving the combination treatment compared to the untreated groups. In a multivariate analysis controlling for baseline Hb imbalance and mechanical ventilation, receipt of steroids remained associated with a slower decline in Hb level and the combination treatment remained associated with a slower decline of Hb and with less transfusions. Results remained the same in the validation cohort. CONCLUSION Immunomodulatory treatment was associated with a slower decline in Hb level in critically ill patients with COVID-19 and with less transfusion. Findings point toward inflammation as an important cause for the occurrence of anemia in the critically ill.

Abstract
Migrant patients share the same diseases as natives, but biological or environmental differences may lead to distinct prevalence and manifestations of certain syndromes. Some common conditions in Primary Care stand out, such as fever, diarrhea, anemia, eosinophilia, and chronic cough, where it is important to have a special consideration. Fever may indicate a serious imported illness, and malaria should always be ruled out. Diarrhea is generally of infectious origin, and in most cases, management is outpatient. Anemia may indicate malnutrition or malabsorption, while eosinophilia may indicate a parasitic infection. Lastly, chronic cough may be a sign of tuberculosis, especially in immigrants from endemic areas. Family medicine holds a privileged position for the comprehensive, culturally sensitive, and person-centered approach to these conditions.

Abstract
BACKGROUND Emerging evidence has suggested significant associations between ambient air pollution and changes in hemoglobin levels or anemia in specific vulnerable groups, but few studies have assessed this relationship in the general population. This study aimed to evaluate the association between long-term exposure to air pollution and hemoglobin concentrations or anemia in general adults in South Korea. METHODS A total of 69,830 Korean adults from a large-scale nationwide survey were selected for our final analysis. Air pollutants included particulate matter with an aerodynamic diameter less than or equal to 10 micrometers (PM10), particulate matter with an aerodynamic diameter less than or equal to 2.5 micrometers, nitrogen dioxide, sulfur dioxide (SO2), and carbon monoxide (CO). We measured the serum hemoglobin concentration to assess anemia for each participant. RESULTS In the fully adjusted model, exposure levels to PM10, SO2, and CO for one and two years were significantly associated with decreased hemoglobin concentrations (all p < 0.05), with effects ranging from 0.15 to 0.62% per increase in interquartile range (IQR) for each air pollutant. We also showed a significant association of annual exposure to PM10 with anemia (p = 0.0426); the odds ratio (OR) [95% confidence interval (CI)] for anemia per each increase in IQR in PM10 was estimated to be 1.039 (1.001-1.079). This association was also found in the 2-year duration of exposure (OR = 1.046; 95% CI = 1.009-1.083; adjusted Model 2). In addition, CO exposure during two years was closely related to anemia (OR = 1.046; 95% CI = 1.004-1.091; adjusted Model 2). CONCLUSIONS This study provides the first evidence that long-term exposure to air pollution, especially PM10, is significantly associated with reduced hemoglobin levels and anemia in the general adult population.

Abstract
BACKGROUND Population of patients with inflammatory bowel disease (IBD) is burdened by various extraintestinal manifestations which substantially contribute to greater morbidity and mortality. Growth-differentiation factor-15 (GDF-15) is often over-expressed under stress conditions, such as inflammation, malignancies, heart failure, myocardial ischemia, and many others. AIM To explore the association between GDF-15 and IBD as serum concentrations of GDF-15 were shown to be an independent predictor of poor outcomes in multiple diseases. An additional aim was to determine possible associations between GDF-15 and multiple clinical, anthropometric and laboratory parameters in patients with IBD. METHODS This cross-sectional study included 90 adult patients diagnosed with IBD, encompassing both Crohn's disease (CD) and ulcerative colitis (UC), and 67 healthy age- and sex-matched controls. All patients underwent an extensive workup, including colonoscopy with subsequent histopathological analysis. Disease activity was assessed by two independent gastroenterology consultants specialized in IBD, employing well-established clinical and endoscopic scoring systems. GDF-15 serum concentrations were determined following an overnight fasting, using electrochemiluminescence immunoassay. RESULTS In patients with IBD, serum GDF-15 concentrations were significantly higher in comparison to the healthy controls [800 (512-1154) pg/mL vs 412 (407-424) pg/mL, P < 0.001], whereas no difference in GDF-15 was found between patients with CD and UC [807 (554-1451) pg/mL vs 790 (509-956) pg/mL, P = 0.324]. Moreover, multiple linear regression analysis showed that GDF-15 levels predict CD and UC severity independent of age, sex, and C-reactive protein levels (P = 0.016 and P = 0.049, respectively). Finally, an association between GDF-15 and indices of anemia was established. Specifically, negative correlations were found between GDF-15 and serum iron levels (r = -0.248, P = 0.021), as well as GDF-15 and hemoglobin (r = -0.351, P = 0.021). Accordingly, in comparison to IBD patients with normal hemoglobin levels, GDF-15 serum levels were higher in patients with anemia (1256 (502-2100) pg/mL vs 444 (412-795) pg/mL, P < 0.001). CONCLUSION For the first time, we demonstrated that serum concentrations of GDF-15 are elevated in patients with IBD in comparison to healthy controls, and the results imply that GDF-15 might be involved in IBD pathophysiology. Yet, it remains elusive whether GDF-15 could serve as a prognostic indicator in these patients.
