Effect of Iron Deficiency Anemia on HbA1c Levels in a cohort of patients with Type 2 diabetes mellitus in a tertiary care hospital

Introduction: Studies have reported that HbA1c levels can be changed by iron deficiency (ID) which is the commonest nutritional anaemia globally. This study was aimed at determining the effect of iron deficiency anaemia (IDA) on HbA1c levels in a cohort of type 2 diabetes mellitus (T2DM) attending a tertiary care hospital in Sri Lanka. Methods: A retrospective analytical study was performed for a period of six months from January 2021. Laboratory records of 281 adult T2DM patients both, anaemic (n=135) with Hb <12g/dL in females and <13g/dL males and transferrin saturation <16%, and nonanaemic (n=146) with Hb >12g/dL in females and >13g/dL in males were analyzed. Data were analyzed using (SPSS) version 20, descriptive statistical methods, Pearson’s Correlation test, independent sample t-test, one-way analysis of variance (ANOVA) and Chi-Square test were used. P<0.05 was considered significant. Results: Out of the total 281 patients diagnosed with T2DM, 150 were female, and 131 were male, spanning an age range of 22 to 96 years. The mean ± standard deviation (SD) values for HbA1c in both anaemic and non-anemic groups were 7.4±2.2% g/dL and 7.3±2.36% g/dL, respectively. Importantly, no statistically significant relationship was observed between the two groups (p=0.889). Furthermore, there was no significant correlation between HbA1c levels with serum iron (p=0.617), total Iron Binding Capacity (TIBC) (p=0.340), and transferrin saturation (p=0.168). Conclusion: The study reveals, HbA1c in T2DM patients with and without IDA show no significant difference. Therefore, HbA1c could be reliably used in monitoring patients with T2DM and IDA.

Prognostic value of reticulocyte production ability in patients with chronic heart failure

Abstract Background Anaemia is frequently observed in patients with chronic heart failure (CHF), and many studies have elucidated the association between anaemia and mortality in patients with CHF. The quality of erythropoiesis is an intrinsic aspect of pathophysiology of anaemia, and the ability of reticulocyte production would be one of the pivotal factors in the quality of erythropoiesis. Purpose We sought to investigate whether the reticulocyte production ability is associated with clinical outcomes, and clarify the pathophysiology of reticulocyte production in patients with CHF. Methods We prospectively examined 1,328 symptomatic CHF patients (median age 71 [IQR 65-82] years, mean left ventricular ejection fraction 50 ± 16%, median NT-proBNP 743 [IQR 360–1710] pg/mL) in a multicentre registry with 27 Japanese sites between January 2020 and October 2023. The reticulocyte production ability was evaluated by calculating the reticulocyte production index (RPI) using reticulocyte counts and serum haematocrits. Patients were divided into four groups according to the presence or absence of WHO defined anaemia and the median value of RPI. The primary outcome was a composite of all-cause death and hospitalisation for worsening HF. Results During a median follow-up period of 551 (IQR 321–712) days, the primary outcome occurred in 219 (17%) patients. The group with anaemia and high RPI (≥0.978, the median) showed the highest incidence of the primary outcome among the groups (P < 0.001) (Figure 1). Multivariable regressions showed that higher RPI was independently associated with the higher risk of the primary outcome, even after adjustment for NT-proBNP, sodium, haemoglobin, serum iron, erythropoietin, and MAGGIC risk score (HR 1.41, 95% CI 1.09–1.82). Erythrocyte counts were significantly increased in patients with higher RPI compared to those with lower RPI in the groups without anaemia (P < 0.001)whereas there were no significant differences on erythrocyte counts between the groups with anaemia (P = 0.90) (Figure 2A). Patients with higher RPI had higher log erythropoietin levels compared to those with lower RPI in either anaemic or non-anaemic group (Figure 2B). In addition, serum iron levels and transferrin saturation did not significantly differ between the RPI groups in either anaemic or non-anaemic group (Figures 2C and D). Furthermore, in patients without anaemia, erythrocyte counts positively correlated with RPI (R = 0.27, P < 0.001) whereas there was very weak correlation between erythrocyte counts and RPI in those with anaemia (R = 0.07, P = 0.045). Conclusions Higher RPI was independently associated with worse clinical outcomes, suggesting RPI could be a surrogate marker for risk stratification in patients with CHF, especially in anaemic population. Higher reticulocyte production ability might reflect the impaired maturation of reticulocytes to erythrocytes independent of iron parameters.

The connection between anemia and limitations in daily activities among older males: the critical role of dynapenia

AimThe aim of the present study was to examine the relationship between anemia and basic and instrumental activities of daily living in older male patients.MethodsA total of 223 older males attending one geriatric outpatient clinic were included in this cross-sectional study. Anemia was defined as a hemoglobin level below 13 g/dL. Patients’ demographic characteristics, comorbidities, and comprehensive geriatric assessment parameters were also recorded. Handgrip strength of < 27 kg for males was accepted as dynapenia. Basic Activities of Daily Living (BADL) and Instrumental Activities of Daily Living (IADL) questionnaires were used to evaluate functional capacity.ResultsThe mean age (standard deviation) of the participants was 80.17 (7.69) years. The prevalence of patients with anemia was 43.9%. There was differences between anemic and non-anemic groups in terms of presence of diabetes mellitus (DM), congestive heart failure (CHF), chronic kidney disease (CKD), malnutrition, dynapenia, geriatric depression, BADL and IADL scores (all p < 0.05). In multivariate analysis, after adjusting for all confounding variables except for dynapenia, patients with anemia were associated with reduced BADL and IADL (all p < 0.05). After adjusting for all confounding variables including dynapenia, deterioration in total BADL and IADL scores did not remain significant in the anemic group compared to the non-anemic group (p > 0.05).ConclusionClose to one in two older outpatient men had anemia. Anemic men had a higher incidence of DM, CHF, CKD, malnutrition, geriatric depression and dynapenia. Anemia was associated with dependence in both BADL and IADL in older men. However, comorbidities, nutritional status, depressive mood and, specifically muscle strength, were important contributors to this association.

Characteristics of Gut Microbiota and Fecal Metabolites in Patients with Colorectal Cancer-Associated Iron Deficiency Anemia.

Patients with colorectal cancer (CRC) have a high prevalence of iron deficiency anemia (IDA), and the gut microbiota is closely related to iron metabolism. We performed metagenomic and metabolomic analyses of stool samples from 558 eligible samples, including IDA CRC patients (IDA, n = 69), non-anemia CRC patients (Non-Anemia, n = 245), and healthy controls (CTRL, n = 244), to explore the dynamically altered gut microbes and their metabolites. Compared with the CTRL group, fecal bacteria in both the IDA group and the Non-Anemia group showed a decrease in alpha diversity and changes in microbial communities. Flavonifractor plautii (F. plautii) increases progressively from CTRL to Non-Anemia to IDA, accompanied by decreased trimethoxyflavanone and a downregulated KO gene, megDIII. In the Non-Anemia group, Parabacteroides showed a specifically elevated abundance positively correlated with enriched 1,25-dihydroxyvitamin D3. The intricate correlations among gut microbiota, metabolites, and KO genes were uncovered and highlighted, implicating an aberrant iron metabolism vulnerable to chronic inflammation during the deterioration of the anemic condition. Furthermore, the amount of F. plautii in feces achieved independent and effective prediction performance for the poor outcome of CRC. Perturbed host-microbe interplays represent a novel prospect for explaining the pathogenesis of CRC-associated IDA. The fecal microbial features also reflect the associations between IDA and elevated CRC recurrence risk.

Correlation of tuberculosis-related anemia severity with tuberculosis-induced inflammation in children: a six-year retrospective study

BackgroundAnemia is a common complication of tuberculosis (TB), and there is evidence that its prevalence is higher in patients with TB. Although TB is very important in epidemiology, careful investigation of TB-related anemia in children has not been carried out systematically. This study aimed to describe the details of anemia in children with TB and its association with clinical characteristics and the severity of inflammation.MethodsIn this retrospective study, we explored Hb levels in 103 children with pulmonary TB (PTB) and they were divided into anemic or non-anemic groups. Logistics regression analysis was used to study the associations between anemia and demographic characteristics. Spearman correlations analysis was performed to analyse the associations between the biochemical parameters and hemoglobin levels in blood.ResultsThe prevalence of anemia in children with TB was 37.9% (48.7% showed microcytic hypochromic anemia, and 5.1% showed normal cell anemia). Compared with the anemia (n = 39) group, the non-anemic group (n = 64) had longer fever duration and increased respiratory rate (P < 0.05). In logistic regression analysis, anemia was associated with lower levels of Alb and higher levels of WBC, CRP, LDH, and ESR (P < 0.05). Spearman correlations analysis showed a significant negative correlation between hemoglobin (Hb) levels and inflammatory markers. After one month of antitubercular therapy (ATT), the Hb levels of 76.9% children returned to normal.ConclusionsAnemia is common among children with TB at diagnosis. The majority of children with TB-related anemia are mild to moderate microcytic hypochromic anemia. There is a strong correlation between the severity of anemia and the inflammation induced by TB. This suggests that anemia is a biomarker of the severity of TB in clinical practice among children.

Prevalence and associated Factors of Anemia in Diabetic Patients

Introduction: Diabetes presents a significant global health challenge due to its association with a range of pathological changes, such as metabolic, cellular, and blood disturbances, that lead to long-term microvascular and macrovascular complications. Healthcare providers often underestimate anemia as a co-morbidity in diabetes, despite the wide range of prevalence estimates reported in the literature. Addressing anemia in diabetes patients early can reduce the incidence of these complications, as has been demonstrated. Aim of the study: The study aimed to estimate the prevalence of anemia and its associated factors among patients with type 2 diabetes mellitus (T2DM). Methods: This is a cross-sectional prospective study with a retrospective review of diabetic patient medical records attending family medicine clinics at four military hospitals (King Hussien Medical Center, Prince Rashed Military Hospital, Queen Aliah Military Hospital, and Prince Hashem Military Hospital) at Royal Medical Services. Adult patients over the age of 18 diagnosed with type 2 diabetes mellitus for more than one year will be included in the study. However, those patients with diseases (such as thalassemia and leukemia) or other systemic disorders (such as infectious diseases) that could result in anemia, those with acute conditions such as acute hemorrhage, those who received blood transfusions in the last three months, pregnant women, or type 1 diabetes will be excluded. Anemia will be defined as hemoglobin level &lt; 13 g/dl in men and 12g/dl in females (Harrison TR, 2011). Type 2 DM will be defined glycated hemoglobin (HbA1c &gt; 6.5%), fasting blood glucose (FBG &gt; 126 mg/dl), random blood glucose (RBG &gt; 200 mg/dl) (American Diabetes Association, 2012). Patients’ medical records will be reviewed for patient medications, duration of diabetes, diabetic complications, and glycemic control. Furthermore, to exclude any patients who have one or more of the aforementioned conditions reported in the exclusion criteria. Meanwhile, researcher will collect the following data in the clinic after patients’ agreement to participate in the study which include: age, sex, marital status, smoking status, comorbidities, anthropometric measurements including weight, height and body mass index (BMI). Moreover, patient will ask to withdraw complete blood count (CBC) blood sample which include hemoglobin, mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH) and mean corpuscular hemoglobin concentration (MCHC) for diagnosing anemia if its present. Patients will be divided into two groups based on the presence of anemia; anemic group and non-anemic group. Regarding study variables. Glycemic control will be classified into two categories based on HbA1c result (controlled diabetic group comprised those whose HbA1c level was equal to or &lt;7.5% and poorly controlled diabetic group comprised those whose HbA1c level was &gt;7.5%). Body mass index will classify according to Center of Disease Control (CDC) as follow: BMI score &lt; 18.5 Kg/m2 is underweight, 18.5–24.9 Kg/m2 is normal, 25–29.9 Kg/m2 is overweight and BMI ≥ 30 Kg/m2 is obese. The sample size will be calculated based on Cohran’s sample size formula as: n=Z2 pq /e2. Here, p will be the anticipation of anemia prevalence in the diabetic population, q=1 - p; e is an acceptable error (5%); and Z= 1.96. A simple random sampling (systematic procedure) will be used to choose patients with type 2 diabetes in order to reduce the possibility of selection bias. With this technique, we randomly choose the first subject and then select the next subjects in a periodic manner according to K (interval). K will be determined based on the sampling frame prepared by researchers divided by n. Descriptive analysis will be used with the mean (standard deviation) for normally distributed variables and the median (inter-quartile range) for highly skewed distributions. The t-test and the Mann-Whitney test will be used to compare the baseline characteristics of quantitative variables between anemic and non-anemic groups for variables with a normal and highly skewed distribution, respectively. Categorical variables will be compared between the groups using the chi-square test. Logistic regression analyses will be employed to find out how these variables are associated with anemia. The results will be given as odds ratios (ORs) with a 95% confidence interval (CI). We will select only covariates with a p-value &lt;0.20 in the univariate analysis to enter the logistic analysis.

A call for improved anemia treatments in myelofibrosis: A single-center retrospective study.

e18531 Background: Anemia in myelofibrosis (MF) is associated with poor prognosis and decreased quality of life. Effective treatments are limited, posing a significant challenge in clinical management. This study aims to provide insights into the treatment of anemia in MF patients from an underserved urban tertiary care center. Methods: We retrospectively reviewed 88 MF patients referred to our center in the Bronx, NY between 2000 and 2023. Demographic data, presence of anemia (hemoglobin ≦10 g/dl) at time of diagnosis or referral (TODR), transfusion dependence ( ≥ 2 units on ≥2 occasions within 8 weeks), anemia treatments, disease modifying treatment, and anemia response to treatments (as defined by the IWG-MRT and ELN consensus report) were assessed via non-parametric tests and univariate cox regression. Events were defined as death from any cause or development of anemia. Patients with missing data were excluded. Results: Among 88 patients analyzed, 77 (87.5%) experienced anemia during the study period. Overall survival (OS) for anemic patients was 7.7 years with 31 deaths, versus only 1 death in the non-anemic group. 51 (60%) of patients were anemic at TODR. For patients not anemic at TODR, median time to anemia (TTA) was 31 months. Patients with HMR (n=24) had faster median TTA than those without (22 vs. 49 months, p = 0.1). All triple-negative (TN) patients (n=8) were anemic at TODR and had statistically lower initial hemoglobin compared to patients with driver mutations (7.4 g/dl vs. 9.9 g/dl, p = 0.0023). Among anemic patients (n=77), age &gt; 65 was associated with poorer OS (HR 2.293, CI 1.076 - 4.887, p=.0315), while transfusion dependency (HR 2.093, CI 0.4777 - 0.9422, p=0.0697) and Ruxolitinib use (HR 2.843, CI 0.9912 - 8.155, HR 0.052) approached significance. Secondary anemia treatments did not impact OS (HR 0.9346, CI 0.4537 - 1.925, p=.854) and are summarized in the table. Most patients received Ruxolitinib (68.8%) and hydroxyurea (35.06%), while fewer received Momelotinib (N = 4), Pacritinib (N = 6), or Fedratinib (N = 4). Conclusions: Our findings highlight the limited effectiveness of current treatments in reducing transfusion burden and anemia in MF, and that patients of higher genetic risk may be more susceptible to developing anemia. Transfusion dependency and treatment non-response are marginally associated with poorer outcomes, emphasizing the need for newer therapies. [Table: see text]

Readmission Trends and Outcomes of Transcatheter Edge-to-Edge Repair of Mitral Regurgitation With and Without Anemia.

Anemia is associated with worse clinical outcomes in cardiac patients. We aim to investigate the clinical outcomes and readmission rates in anemic patients undergoing transcatheter edge-to-edge repair (TEER) for severe mitral valve regurgitation (MR). The National Readmissions Database (NRD) from 2015 to 2018 was queried using the ICD-10 codes to identify patients admitted for TEER. Patients were divided into anemic and non-anemic sub-groups. Univariate and multivariate analyses were performed. Cardiovascular outcomes were assessed between cohorts at index admission and readmissions at 30, 90, and 180 days. STATA v.17 was used for analysis (StataCorp LLC, Texas, USA). Our final cohort included 28,995 patients who had undergone TEER in the United States between 2016 and 2019. About 1,434 (4.9%) had a diagnosis of anemia. The mean age of patients who had TEER with anemia and TEER without anemia was 76.9 ± 10.8 vs. 77.7 ± 10.2, respectively. In the adjusted model, anemic patients had higher odds of acute kidney injury (AKI) (aOR 2.21; 95% [CI 1.81-2.6; p<0.001]), HF (aOR 1.75; 95% [CI 1.28-2.3; p<0.001]), myocardial infarction (MI) (aOR 1.54; 95% [CI 1.01-2.33; p<0.041]), major adverse cardiac and cerebrovascular events (MACCE) (aOR 1.72; 95% [CI 1.2-9-2.3; p<0.001]), and net adverse event (aOR 1.85; 95% [CI 1.32-2.59; p<0.001]). The anemic group's readmission rate was overall higher at 30, 90, and 180 days from 2016 to 2019. Anemia was associated with increased adverse clinical outcomes and more extended hospital stays in patients with anemia who had undergone TEER procedures compared to the non-anemic group.

A Comprehensive Assessment of Prescription Patterns for Anemia Management in Pregnant Women: A Study From Anand District, India.

Introduction Pregnancy induces various physiological changes, often leading to complications. Physiological anemia of pregnancy, resulting from increased plasma volume and erythropoietin levels, poses significant health risks.Adverse outcomes associated with anemia during pregnancy include maternal and perinatal mortality, premature delivery, and low birth weight. Drug utilization research aims to promote rational drug use for improving health outcomes. The Food and Drug Administration (FDA) categorizes drugs based on teratogenic risk, providing guidance for clinicians. This study aims to analyze prescription trends and FDA risk categories for anemia in pregnant women in the Anand district. Materials and methods The study received institutional ethics approval and involved 816 pregnant women attending antenatal clinics from December 2021 to March 2023. Participants provided informed consent, and data collection included hemoglobin (Hb) levels at each trimester, categorizing participants into anemic (Hb < 11 gm/dL) and non-anemic groups. Prescribed drugs were recorded, and their essentiality was assessed using the WHO Essential Medicines List (WHO-EML) and the National List of Essential Medicines-2022 (NLEM-2022). FDA drug risk categories were utilized for assessing drug safety. Descriptive and statistical analyses were performed. Results Anemia prevalence across trimesters ranged from 62.50% to 65.93%, with an overall average of 64.42%. Iron and folic acid supplementation were significant across trimesters, with varying rates of prescription. Calcium supplementation showed fluctuations, with 100% prescription rates in later trimesters. Ascorbic acid was significantly prescribed in anemic pregnant women throughout pregnancy. Multivitamins were consistently prescribed, emphasizing their importance. The WHO-EML and NLEM-2022 highlighted essential micronutrients, while FDA categories indicated drug safety. Conclusion Anemia prevalence remained high throughout pregnancy, emphasizing the need for consistent supplementation. Prescription patterns aligned with evidence-based guidelines, focusing on iron and folic acid supplementation. Variations in calcium prescription suggest trimester-specific considerations. Prescription trends reflect a responsible approach to managing anemia during pregnancy, emphasizing prophylactic iron and folic acid therapy. The absence of high-risk medications underscores cautious prescribing practices. This study contributes valuable insights into evidence-based pharmacotherapy and maternal health care.

Tuberculosis Co-infection among HIV/AIDS Cases Attending an Anti-retroviral Therapy Center: A Retrospective Cohort Study from Pakistan

Objective: The co-occurrence of tuberculosis (TB) and human immunodeficiency virus (HIV) results in heightened morbidity and mortality, placing an increased burden on healthcare systems. This study aims to assess the incidence and identify associated risk factors for TB/HIV co-infection, with the objective of enhancing the survival rates of co-infected patients in Pakistan. Methods: This retrospective cohort investigation took place at the Anti-Retroviral Treatment Center in Islamabad, Pakistan. Data spanning a decade (January 2006 to December 2016) were extracted from 2,542 people living with HIV using a pre-tested data extraction tool. Results: Following the exclusion of 156 ineligible participants, records of 2,386 individuals were analyzed over 4,433 person-years. The cumulative incidence and incidence rate of TB among HIV/AIDS patients were 446 (18.7%) and 0.001 cases/10,000 person-years, respectively. The majority (81%) of incident TB cases occurred within one year, predominantly manifesting as pulmonary TB. Of the TB-infected individuals, 98.6% received TB medication, with 0.7% prescribed Isoniazid prophylaxis. Significant associations with TB were identified in relation to work abroad history, patient age, and current HIV stage (P&lt;0.05). Binary logistic regression indicated a 3.1 times higher likelihood of TB infection in the anemic group compared to the non-anemic group. HIV/AIDS infection emerged as a consistent TB risk factor irrespective of CD4 count and WHO HIV staging. Conclusion: This study highlights a substantial incidence of TB co-infection among HIV patients in Pakistan, emphasizing the need for comprehensive efforts by the National AIDS Control and National TB Control Programs to effectively manage co-infection.

Factors associated with increased risk of postoperative blood transfusion in patients undergoing total hip arthroplasty at an Irish University Hospital

IntroductionApproximately 7000 total hip arthroplasty (THA) surgeries occur in Ireland each year. A number of preoperative factors have been identified that increase the risk of postoperative blood transfusion after THA, including anaemia. The ability to identify patients at risk may allow preoperative management strategies to reduce blood transfusions. Data from Irish orthopaedic patients is currently lacking.AimTo investigate if preoperative anaemia and other factors are associated with postoperative blood transfusions in patients who undergo THA.MethodsA retrospective cohort study of all patients who underwent THA in 2019 in SIVUH, Cork, using medical chart review.ResultsIn total, 350 charts met the inclusion criteria, with 291 charts reviewed. 8.9% of the patients who underwent THA had preoperative anaemia. Among these, 19.2% had a postoperative blood transfusion, compared to 1.5% of patients who were not anaemic preoperatively. The odds of receiving a blood transfusion was 15.5 times greater in the preoperative anaemia group compared to the non-anaemic group. Increasing age and higher ASA scores were associated with preoperative anaemia and postoperative blood transfusions. Length of stay was increased by 2.2 days (p < 0.00016) if blood transfusion was required.ConclusionPreoperative anaemia was common in an Irish orthopaedic population undergoing THA. Preoperative anaemia predisposes patients to the greatest increased risk of postoperative blood transfusions. The other factors associated with the need for postoperative transfusion were ASA grade 3 or more and age greater than 65 years. Patients who received postoperative blood transfusions had a significantly increased length of hospital stay.

Study of the association between anemia and prognosis of moderate-to-severe traumatic brain injury

Objective: To investigate the impact of admission anemia on the prognosis of patients with moderate- to-severe traumatic brain injury (TBI). Methods: The clinical data of patients with moderate-to-severe TBI treated in the Department of Intensive Care Unit in our hospital from January 2020 to September 2022 were retrospectively analyzed. The patients were divided into admission non-anemia group (Hb ≥ 100 g/L) and admission anemia group (Hb&lt;100 g/L) based on hemoglobin (Hb) levels. The Glasgow Coma Scale (GCS) score, first blood analysis, arterial blood gas, blood pressure, injury mechanism, pupillary reflex at admission and others were compared, multivariate logistic was used to analyse independent risk factors for patient death. Results: One hundred and nine patients were included in the study, of which 17 died in the hospital and 52 had anemia at admission. Compared with patients in the admission non-anemia group, patients in the admission anemia group were younger, had lower admission GCS and trauma score (PTS) scores, higher mortality rates, and longer hospital stay (all P&lt;0.05).Univariate analysis showed that moderate-to-severe TBI patients with admission anemia, admission hyperglycemia, GCS&lt;8, PTS&lt;8, abnormal pupillary reflex, and other organ injuries had higher mortality rates (all P&lt;0.05) .Multivariate logistic regression analysis showed that admission anemia (OR=9.383, 95% CI=1.086~81.094, P=0.042), admission pupillary reflex abnormalities (OR=23.121,95% CI=3.680~145.270,P=0.001), and admission hyperglycemia (OR=15.181, 95% CI=2.019~114.160, P=0.008) are independent risk factors for death of Moderate-to-severe TBI patients. Conclusions: Admission anemia is an independent risk factor for death of moderate-to-severe TBI patients, and it can prolong the length of hospital stay for such patients.

The mean reticulocyte volume is a valuable index in early diagnosis of cancer-related anemia.

Cancer-related anemia (CRA) is a functional iron deficient anemia, and the early diagnosis will improve the prognosis of the patients. This prospective study aimed to investigate the utility of mean reticulocyte volume (MRV) in the early diagnosis of CRA. A total of 284 first-diagnosed cancer patients were enrolled, and the subjects were assigned anemia and non-anemia groups by hemoglobin (Hb) concentrations. The mature RBC and reticulocyte indices were detected with BC-7500 blood analyzer, and the MRV, reticulocyte hemoglobin (RHE) content, and reticulocyte production index (RPI) were obtained. ROC curves were constructed in identifying anemia diagnosed by the combination of RHE and RPI. An adjusted multivariate analyse and quartiles were used to assess the associations of MRV with early CRA diagnosed by combining RBC indices (MCV, MCH and MCHC), respectively. No statistical differences were observed in MCV, RHE and MRV levels between anemia and non-anemia subjects (p>0.05). MRV exhibited a complete or high correlation with the RHE levels (r=1.000, p<0.001), or MCV, MCH, and MCHC in anemia patients (R: 0.575-0.820, p<0.001). ROC curves analyse indicated a highest area under curve of 0.829 (95% CI [0.762-0.895]) and 0.884 (95% CI [0.831-0.936]) for MRV in identifying anemia in male and female patients, respectively (p<0.001). When the optimal cutoff values of MRV were set at 100.95 fl in males and 98.35 fl in females, the sensitivity and specificity were 1.00 and 0.68, and 1.00 and 0.73, respectively. The regression analyse showed that, when being as a categorical variable, MRV showed an odds ratio of 19.111 (95% CI [6.985-52.288]; p<0.001) for the incidence of CRA. The incidence of overall anemia demonstrated a more significant decrease trend along with the increase of MRV quartiles (p-trend < 0.001). This study revealed that the MRV can be used as a convenient and sensitive index in early diagnosis of cancer-related anemia, and decreased MRV level may be the powerful predictor of overt anemia in cancer patients.

Association of Gestational Iron-deficiency Anemia with Antenatal Depression among Pregnant Women: A Case-control Study from Tertiary Care Hospitals, Lahore.

The goal of this study is to investigate the potential association between gestational anemia and antenatal depression in pregnant women. It is a case-control study consisting of 684 pregnant women under 18 years recruited in different tertiary care hospitals, in Lahore, between June 2023 and December 2023. Utilizing an online questionnaire, data collection encompassed demographics, dietary habits, and the Edinburgh Postnatal Depression Scale (EPDS). Pregnant women with antenatal hemoglobin (Hb) levels above and below 11.0 g/dL were categorized as a nonanemic and anemic group. Statistical analysis involved Chi-square tests to explore the relationships between gestational parameters and maternal factors. The depression scores of anemic and nonanemic pregnant women compare two groups of pregnant women based on their Hb levels: those with Hb <110 g/l during pregnancy (anemic) and those with Hb ≥110 g/l (nonanemic). The anemic group had higher depression scores than the nonanemic group, both for those with EPDS <12 points and those with EPDS ≥12 points. However, P = 0.077 indicates that this difference was not statistically significant at a typical alpha level of 0.05. No significant association was found between gestational anemia and antenatal depression in pregnant women. These findings prompt further research to unravel the intricacies of the association between gestational anemia and depression. The outcomes thus urge the researchers and health-care professionals to consider the diverse factors that may contribute to mental health outcomes during pregnancy and refine strategies for maternal care.

Determinants of anemia among pregnant women attending a tertiary hospital, Mogadishu, Somalia: unmatched case-control study.

The objective of this study was to identify the factors associated with anemia among pregnant women attending a tertiary referral hospital in Mogadishu, Somalia. An unmatched case-control study was conducted on pregnant women who visited the antenatal clinics of a tertiary referral hospital between March and July 2021. The study recruited pregnant women who had a hemoglobin level of <11 g/dL into the anemic group, while those with hemoglobin levels ≥11 g/dL were included in the non-anemic group. Demographics, clinical, obstetrics, nutrition-related, hygiene- and sanitation-related, and parasitic infection-related data were collected. A total of 449 pregnant women (399 anemic and 50 non-anemic) participated in the study. A total of 224 (56.7%) in the anemic group and 31 (62.0%) in the non-anemic group did not consume any dark green, leafy vegetables such as spinach, bukurey, cagaar, and koomboow (p=0.040). Notably, 255 (63.9%) in the anemic group and 21 (42.0%) in the non-anemic group had a middle-upper arm circumference <23 cm. More than half of anemic [335 (84%)] and non-anemic [46 (92.0%)] were classified under low dietary diversity score. Majority of the study participants, 288 (72.4%) of the anemic and 39 (78%) of the non-anemic groups, used pit toilets in dwellings, and 70.2% (134/191) of the anemic and 64.4% (246/382) of the non-anemic groups disposed of solid waste in open fields. This study demonstrated that women who consumed green vegetables such as spinach, bukurey, cagaar, and koomboow in their diet had middle-upper arm circumference less than 23 cm, and those with low dietary diversity significantly developed anemia during pregnancy.

Analysis of risk factors and changes in myocardial biomarker levels in 122 cases of early neonatal anemia.

Anemia in the first week after birth, which could affect growth, development, and organ function, should be an important warning sign to clinicians. The aim of this study was to assess the related risk factors of early neonatal anemia and to analyze the effect of anemia on the expression levels of myocardial markers in newborns. Clinical data from 122 confirmed cases of anemic newborns and 108 nonanemic newborns were collected to analyze the independent risk factors for early anemia using logistic regression analyses. Blood samples were collected from both groups for the detection of myocardial markers, including the protein marker cardiac troponin T (cTnT), as well as enzyme markers creatine kinase isoenzyme MB (CK-MB) and lactate dehydrogenase (LDH). Multivariate logistic regression analysis revealed that preterm birth (OR: 3.589 [1.119-11.506], p < 0.05), multiple pregnancy (OR: 4.117 [1.021-16.611], p < 0.05), and abnormal placenta (OR: 4.712 [1.077-20.625], p < 0.05) were independent risk factors for early neonatal anemia. The levels of myocardial markers, including cTnT (303.1 ± 244.7 vs. 44.2 ± 55.41 ng/L), CK-MB (6.803 ± 8.971 vs. 2.5326 ± 2.927 μkat/L), and LDH (32.42 ± 35.26 vs. 19.73 ± 17.13 μkat/L), were significantly higher in the anemic group than in the nonanemic group. Multiple pregnancy, preterm birth, and abnormal placenta were identified as risk factors for early neonatal anemia. The occurrence of early neonatal anemia was associated with increased levels of myocardial markers.

THE INFLUENCE OF ANEMIA ON MATERNAL AND NEONATAL OUTCOMES IN TEEN AGED PREGNANT WOMEN

This retrospective study, conducted between October 2022 and October 2023 at Maroof International Hospital &amp; Life Care International Hospital in Pakistan, aimed to assess the impact of anemia on neonatal and maternal outcomes in teenage pregnancies. The study included 585 pregnant women aged 13-19 years, with data collected on various parameters such as demographic details, pregnancy-related information, hemoglobin levels during the last trimester, birth weight, gestational age at birth, obstetric complications, neonatal intensive care admissions, and Apgar scores. Among the 585 participants, 212 (36.2%) were identified as having anemia. Further classification revealed that 57.5% experienced mild anemia, 39% had moderate anemia, and 3.5% had severe anemia. Educational status and irregularities in antepartum care showed significant differences between anemic and non-anemic groups (P &lt; 0.05). Anemia was notably higher in women with lower education levels and irregular antenatal care. The study found that anemia significantly increased the risks of postpartum hemorrhage (P=0.005) and postpartum transfusion (P&lt; 0.001). Additionally, infants born to anemic mothers exhibited a significantly higher rate of neonatal intensive care unit (NICU) admission (P&lt;0.001). Maternal anemia was also significantly associated with low birth weight, small for gestational age (SGA), and preterm delivery. However, anemia had no significant impact on Apgar scores. In conclusion, the study underscores the prevalence of anemia in teenage pregnancies and emphasizes its adverse effects on both fetal and maternal outcomes. The findings highlight the urgent need for governmental initiatives to enhance essential healthcare accessibility and improve antenatal care for this vulnerable demographic.

Utility of Automated Reticulocyte Research Parameters derived from Beckman Coulter DXH800 in Nutritional Deficiency Anaemias

Introduction: Reticulocyte parameters obtained from the automated analyzers have gained importance not only in the classification of anemias but also in therapeutic monitoring. Their role in nutritional anemia is by far limited to monitoring the hematinic response. The present study aims to describe the distribution of various reticulocyte parameters obtained from Beckman Coulter DXH 800 in cases of nutritional deficiency anemias. Method: Reticulocyte parameters of iron deficiency anemia (IDA) (n=146), megaloblastic anemia (MA) (n=119), and mixed deficiency anemia (n=32) were compared with a non-anemic healthy control group (n=68). Independent sample T-test and one-way ANOVA were used for comparisons. Results: The RET%, MRV, IRF, MSCV, HLR%, RSF, RDWr, and RDWr-SD were significantly higher in MA than in other groups and a significant inverse correlation of Hb was seen with MRV, RDWr, and RDWr-SD. In IDA there was a significant increase in RET%, ARC, IRF, HLR%, HLR#, and RDWr, and a reduction in MRV, MSCV, and RSF. The strongest positive correlation of Hb was with RSF. In the mixed deficiency anemia group, there was an increase in RET%, ARC, IRF, HLR%, HLR#, and RDWr and a reduction in MRV, MSCV, and RSF. Cases on treatment had significantly higher RET%, ARC, and HLR# compared to those without irrespective of etiology. Conclusion: The study strengthens the utility of RSF as a marker of iron-restricted erythropoiesis, and a low RSF and higher MRV in differentiating IDA from mixed deficiency anemia. Irrespective of the etiology, RET%, ARC, HLR%, and HLR# can be utilized for monitoring therapy in nutritional anemias.

Association between different types of preoperative anemia and tumor characteristics, systemic inflammation, and survival in colorectal cancer.

Patients with colorectal cancer often have anemia and other symptoms after diagnosis, especially in patients with advanced colorectal cancer. This study explored the association between different types of preoperative anemia and tumor characteristics and inflammatory response in patients with colorectal cancer and to evaluate the prognosis of patients with different types of anemia before operation. The clinical data of 95 patients with colorectal cancer treated in the Fourth Hospital of Hebei Medical University from February 2016 to January 2018 were retrospectively analyzed. According to the hemoglobin concentration (Hb), mean corpuscular volume (MCV), mean hemoglobin content (MCH) and mean hemoglobin concentration (MCHC), the patients were divided into the non-anemia group, normal cell anemia group, and small cell anemia group. The three groups' general data, oncological characteristics, and mGPS scores were compared. The patients were followed up for five years, and the survival analysis was carried out. The cox proportional hazard regression model was used to analyze the prognostic factors of patients with colorectal cancer. The preoperative anemia rate of patients with colorectal cancer was 43.15% (41/95). There were significant differences in gender, weight loss, CA724, tumor location, tumor size, TNM stage, mGPS score, and positive expression rate of Ki-67 among different anemia groups. There was a significant difference in survival time among a non-anemia group, small cell anemia group, and normal cell anemia group (P<0.05). Multivariate analysis showed that tumor size, TNM stage, distant metastasis, mGPS score, Ki-67 positive expression rate, and anemia type were independent risk factors affecting the prognosis of colorectal cancer patients (P<0.05). The oncological characteristics of colorectal cancer patients with different types of preoperative anemia are different. Preoperative anemia and systemic inflammatory status are independent risk factors for the prognosis of colorectal cancer patients.

Effectiveness of zinc protoporphyrin/heme ratio and ferritin for assessing iron status in preterm infants.

Since iron is crucial for many tissue processes, we, therefore, aimed to assess ferritin and the zinc protoporphyrin to heme ratio (ZnPP/H) as indicators of iron status in preterm newborns, particularly during certain inflammatory episodes. From 170 preterm babies, paired ferritin and ZnPP/H measurements were collected twice (on the first postnatal day and six weeks later). To compare these measures and assess the impact of anemia, sepsis, and packed red blood cell transfusion (PRBT), three different scenarios were considered. Compared to the non-anemic group, the anemic patients' serum ferritin level was considerably lower (p = 0.044), whereas the anemic patients' ZPP/H ratio was significantly greater (p < 0.001). In neonates with sepsis, ferritin levels were considerably greater in both anemic and non-anemic septic neonates compared to neonates without sepsis (p < 0.001 for each). Regarding ZPP/H ratio, no appreciable variations were found between the two groups. In addition, serum ferritin significantly increased following each PRBT (p < 0.001 for each). As a result of each PRBT, the ZPP/H ratio considerably decreased (p < 0.001). As a measure of iron status during particular inflammatory processes like infection and PRBT, ZnPP/H may be more accurate.
