Serum microRNAs as new biomarkers for detecting subclinical hemolysis in the nonacute phase of G6PD deficiency

Glucose-6-phosphate dehydrogenase (G6PD) deficiency is one of the most common enzymopathies worldwide. Patients with G6PD deficiency are usually asymptomatic throughout their life but can develop acute hemolysis after exposure to free radicals or certain medications. Several studies have shown that serum miRNAs can be used as prognostic biomarkers in various types of hemolytic anemias. However, the impact of G6PD deficiency on circulating miRNA profiles is largely unknown. The present study aimed to assess the use of serum miRNAs as biomarkers for detecting hemolysis in the nonacute phase of G6PD deficiency. Patients with severe or moderate G6PD Viangchan (871G > A) deficiency and normal G6PD patients were enrolled in the present study. The biochemical hemolysis indices were normal in the three groups, while the levels of serum miR-451a, miR-16, and miR-155 were significantly increased in patients with severe G6PD deficiency. In addition, 3D analysis of a set of three miRNAs (miR-451a, miR-16, and miR-155) was able to differentiate G6PD-deficient individuals from healthy individuals, suggesting that these three miRNAs may serve as potential biomarkers for patients in the nonhemolytic phase of G6PD deficiency. In conclusion, miRNAs can be utilized as additional biomarkers to detect hemolysis in the nonacute phase of G6PD deficiency.

GAMBARAN TIPE ANEMIA PADA IBU HAMIL BERDASARKAN NILAI INDEKS ERITROSIT DI RSIA RESTU IBU TAHUN 2022

Anemia in pregnant women is a global problem that impacts both mother and fetus. Anemia in pregnancy is associated with maternal morbidity and is an indirect cause of maternal death in the entire population of pregnant women. Classification of anemia based on the erythrocyte index value is divided into normochromic normocytic, normochromic macrocytic, hypochromic microcytic and hypochromic macrocytic anemia. The erythrocyte index values ​​are divided into Mean Corpuscular Volume (MCV), Mean Corpuscular Hemoglobin (MCH) and Mean Corpuscular Hemoglobin Concentration (MCHC). The aim of the research is to describe the types of anemia in pregnant women based on the erythrocyte index value at RSIA Restu Ibu Sragen in 2022. This research uses a quantitative descriptive research type with a retrospective approach. The research sample was 51 medical records of pregnant women who experienced anemia at RSIA Restu Ibu Sragen in January-December 2022 using purposive sampling. The materials and tools used were secondary data from laboratory examination results of pregnant women diagnosed with anemia which included hematocrit, hemoglobin, index erythrocytes (MCV, MCH, and MCHC), Microsoft Excel and SPSS Version 21 software. Data analysis used analysis univariate. The results of the study concluded that pregnant women who experienced anemia at RSIA Restu Ibu Sragen were aged 21-34 years with a third trimester pregnancy and were primigravida. Based on the erythrocyte index, normocytic anemia was normochromic in 18 people (35.3%), microcytic hypochromic anemia in 20 people (39.2%), and macrocytic hypochromic anemia in 13 people (25.5%). So it can be said that most pregnant women experience microcytic hypochromic anemia.

Iron Metabolism, Calcium, Magnesium and Trace Elements: A Review.

Iron (Fe) is fundamental to life on earth. In the human body, it is both essential and harmful if above threshold. A similar balance applies to other elements: calcium (Ca), magnesium (Mg), and trace elements including copper (Cu), zinc (Zn), lead (Pb), cadmium (Cd), mercury (Hg), and nickel (Ni). These elements share some proteins involved in the absorption and transport of Fe. Cu and Cd can inhibit Fe absorption, while excess of Fe may antagonize Cu metabolism and reduce ceruloplasmin (Cp). Excessive Fe can hinder Zn absorption and transferrin (Trf) can bind to both Zn and Ni. Ca is able to inhibit the divalent metal transporter 1 (DMT1) in a dose-dependent manner to reduce Fe absorption and low Mg concentrations can exacerbate Fe deficiency. Pb competitively inhibits Fe distribution and elevated Cd absorption reduces Fe uptake. Exposure to Hg is associated with higher ferritin concentrations and Ni alters intracellular Fe metabolism. Fe removal by phlebotomy in hemochromatosis patients has shown to increase the levels of Cd and Pb and alter the concentrations of trace elements in some types of anemia. Yet, the effects of chronic exposure of most trace elements remain poorly understood.

Post-infectious Moyamoya Syndrome: A Review of Existing Scientific Literature From 2000 to 2023.

Moyamoya disease (MMD) is considered a primary disorder of an unknown etiology. In contrast, Moyamoya syndrome (MMS) refers to MMD associated with other underlying diseases, such as meningitis in childhood, neurofibromatosis type II, Down syndrome, cranial irradiation, and different types of anemias, particularly hemoglobinopathies. We aimed to provide a comprehensive clinicopathological overview of MMS. All case reports and case series published from 2000 to 2023 pertaining to MMD were included in the study. Case studies, original articles, editorials, letters to editors, and clinical images were excluded. The search was conducted using the Boolean operators ("AND" and "OR") on PubMed and Google Scholar. A total of 13 case reports and one case series study were included. The study suggests infection might be a trigger in susceptible individuals. The autoimmune antibody findings (anti-double stranded DNA IgG) suggest a potential autoimmune component in some cases. There were diverse presentations and outcomes of post-infectious MMS, with a striking predominance of pediatric cases (66.66%) and a possible female predominance. Both computerized tomography (CT) and magnetic resonance imaging (MRI) showed evidence of restricted blood flow. CT showed that stenosis, occlusion, and collateral formation were frequent vascular findings, but often unspecified in severity. Infarction, hypodensities, and hematoma were the most common parenchymal findings (22.22% each). The findings on MRI were stenosis (50%) and collateral formation (44.44%). Infarction was the most common finding (66.66%) in parenchyma. Hydrocephalus, encephalomalacia, and atrophy were less frequent. Lesions were most frequent in the internal carotid artery (66.66%),middle cerebral artery (66.66%), and anterior cerebral artery (50%). Lesions were less frequent in the posterior cerebral, vertebral, and basilar arteries. The frontal lobe (38.89%) and basal ganglia (33.33%) were commonly affected parenchymal regions. The most common risk factor was human immunodeficiency virus (HIV) infection (50%), followed by trisomy 21, cryptococcal, and other types of meningitides. Aspirin (50%) and antiretroviral therapy (38.89%) were the cornerstones of treatment for MMS. This review accentuates the noteworthy obstacles presented by post-infectious MMS, especially its catastrophic effect on children and its correlation with HIV/AIDS. According to our elaborate literature search using PubMed and Google Scholar, this is the first narrative review in the existing scientific literature summarizing the literature on post-infectious MMS.

1 Million Segmented Red Blood Cells With 240 K Classified in 9 Shapes and 47 K Patches of 25 Manual Blood Smears

Around 20% of complete blood count samples necessitate visual review using light microscopes or digital pathology scanners. There is currently no technological alternative to the visual examination of red blood cells (RBCs) morphology/shapes. True/non-artifact teardrop-shaped RBCs and schistocytes/fragmented RBCs are commonly associated with serious medical conditions that could be fatal, increased ovalocytes are associated with almost all types of anemias. 25 distinct blood smears, each from a different patient, were manually prepared, stained, and then sorted into four groups. Each group underwent imaging using different cameras integrated into light microscopes with 40X microscopic lenses resulting in total 47 K + field images/patches. Two hematologists processed cell-by-cell to provide one million + segmented RBCs with their XYWH coordinates and classified 240 K + RBCs into nine shapes. This dataset (Elsafty_RBCs_for_AI) enables the development/testing of deep learning-based (DL) automation of RBCs morphology/shapes examination, including specific normalization of blood smear stains (different from histopathology stains), detection/counting, segmentation, and classification. Two codes are provided (Elsafty_Codes_for_AI), one for semi-automated image processing and another for training/testing of a DL-based image classifier.

Frequency, Types, and Risk Factors of Anemia in Pediatric Inflammatory Bowel Disease

Objective: Inflammatory bowel disease patients are prone to be anemic at diagnosis and follow-up. As it is a common extra-intestinal manifestation, its early identification and treatment are essential. We aimed to evaluate the frequency, types, and predictors of anemia and its treatment in pediatric inflammatory bowel disease patients. Methods: The electronic records of pediatric IBD patients who attended our outpatient clinics between 1 April 2018 and 01 May 2019 were retrospectively evaluated. Patients who had the results of hemoglobin, hematocrit, mean corpuscular volume, iron indices, vitamin B12 level, folic acid level, reticulocyte count, C-reactive protein, and erythrocyte sedimentation rate at least once on a single day were included in the study. Laboratory results associated with anemia and disease activity index scores at three- and six-months follow-ups were recorded. Anemia was diagnosed according to WHO criteria in childhood. Anemia, risk factors, and management of anemia were determined. Results: Forty patients were included in the study. At first evaluation, anemia was observed in 38.1% of Crohn’s disease patients and 57.9% of ulcerative colitis patients. Iron deficiency anemia was the main type of anemia in both groups. The rate of anemia decreased at follow-up. Out of 40 patients, 21 had treatment at the initial evaluation. Active disease was the only predictor of iron deficiency anemia. Conclusion: Anemia was common in pediatric inflammatory bowel disease patients, ranging between 25-47.5% during the 6-month follow-up in our study. Iron deficiency anemia was the main type of anemia. Having active disease was the only risk factor for anemia. The treatment of anemia and iron deficiency without anemia should be kept in mind in parallel with anti-inflammatory treatment.

Maternal IgG in hemolytic disease of the fetus and newborn-ABO incompatibility

BACKGROUND Hemolytic disease of the fetus and newborn (HDFN) is a type of anemia in the fetus or newborn, characterized by anemia, jaundice, hyperbilirubinemia, and brain damage. IgG is the only antibody that can cross the placenta. The IgG subtypes have a different ability to destroy red blood cells (RBCs). IgG1 and IgG3 can bind to Fc-phagocyte cell receptors and cause hemolysis, while IgG3 has more ability than IgG1. This study aimed to identify the antibody IgG subtype contributing to clinical manifestation differences in HDFN. METHODS This study used blood and umbilical cord blood samples from 30 pairs of mother-baby. The samples were grouped into control (not jaundice/normal bilirubin levels) and jaundice/hyperbilirubinemia groups. A self-developed IgG subtype enzyme-linked immunosorbent assay protocol was performed on maternal samples, resulting in optical density. Statistical analysis was performed using SPSS software version 23. RESULTS Blood type was associated with total bilirubin expression (p = 0.005). IgG1 anti-A, IgG3 anti-A, IgG4 anti-A, IgG1 anti-B, IgG3 anti-B, and IgG4 anti-B significantly affected hyperbilirubinemia in newborns (p = 0.041, 0.013, 0.017, 0.028, 0.001, and 0.007, respectively). CONCLUSIONS IgG1 and IgG3 were more significant in causing clinical problems. IgG4 suppressed IgG activation, resulting in no destruction of the infant’s RBCs.

Anemia and Iron Profile in Hemodialysis and Nonhemodialysis Patients with Chronic Kidney Disease

Abstract BACKGROUND: Chronic kidney disease (CKD) is a global health concern, with anemia being a significant complication. Anemia in CKD patients is multifactorial and often leads to poorer outcomes. Assessing the iron profile, including serum ferritin, iron, and transferrin saturation, is crucial for identifying absolute or functional iron deficiency anemia (IDA). An objective evaluation of the iron profile is essential for effective and comprehensive management of anemia. MATERIALS AND METHODS: The study involved 100 adult patients with CKD and anemia, who were divided into two groups based on age and sex. The patients were divided into two groups: one received regular hemodialysis (HD) 2–3 times per week, whereas the other received no dialysis or dialysis infrequently. Exclusion criteria included infections, inflammation, renal injury, neoplasms, acute hemolysis, and thalassemia. RESULTS: Anemia is a common complication in patients with CKD, both those on HD and non-HD. Among the types of anemia observed, 50% of HD patients and 72% of non-HD CKD patients have normochromic anemia. In addition, 46% of HD patients and 24% of non-HD patients have IDA. Specifically, 24% of HD patients have absolute IDA and 22% have functional IDA, compared to 12% of both absolute and functional IDA in non-HD CKD patients, with a significant statistical difference between the two groups. Furthermore, serum iron and transferrin saturation levels show significant differences between HD and non-HD CKD patients. CONCLUSION: Anemia, especially IDA in CKD patients undergoing HD, requires accurate diagnosis through transferrin saturation and serum iron levels, and customized treatment based on dialysis status and anemia type is crucial.

Prevalence of Iron Deficiency Anemia and Iron Deficiency Without Anemia Among Moderate and Severely Acute Malnourished Children.

Iron deficiency remains one of the globally recognized leading causes of morbidity and mortality in children, among developing countries like India as compared to the Western world. To estimate the prevalence of iron deficiency anemia (IDA) and iron deficiency without anemia (IDWA) among malnourished children. This cross-sectional study was conducted in the Department Of Pediatrics, Tertiary Care Hospital, Western Rajasthan. Demographic data and serum samples were collected and analyzed. Hematological and biochemical values were determined for 300 children aged 6 months to 59 months. A total of 93.9% of severe acute malnutrition (SAM) children and 83.24% of moderate acute malnutrition (MAM) children had anemia as perWHO definition, with moderate anemia (47.66%) being the predominant type of anemia. About 64% of children showed iron deficiency with a prevalence of IDA and IDWA being 94.27% and 5.72%, respectively. The mean values of serum ferritin, serum iron, serum total iron binding capacity (TIBC), and transferrin saturation in children with IDWA were 8.34±2.85, 17.43±7.57, 454.09±40.76, and 4.09±1.44, respectively. The proportion of anemic children in both SAM and MAM groups was very high. Our study shows that more than 60% of the MAM and SAM children were iron deficient. We recommend future measures for the prevention and control of anemia, including increased coverage of nutritional supplementation, fortification programs, and supplement iron in this sub-group (IDWA) to take care of their symptoms due to iron deficiency even before the development of overt IDA.

Regenerative anemia identification in cats: Red blood cell indices or morphology, what to use?

Anemia, a clinical condition characterized by reduced erythrocytes, is often observed in cats. Regeneration indicates that the bone marrow can respond appropriately to anemia. The absolute reticulocyte count is the reference for differentiating regenerative and non-regenerative anemia, while red blood cell (RBC) indices and morphology provide supplementary information. This study aimed to identify anemia types and establish the most reliable RBC indices and morphology methods in agreement with the reference method. One hundred forty-five cases of cat anemia were prospectively classified using two methods: RBC indices and RBC morphology, and subsequently compared with the absolute reticulocyte count. Based on RBC indices assessment, 27 cases (19%) exhibited regenerative anemia. Based on RBC morphology, 29 (20%) cases were identified as having regenerative anemia. Using the reticulocyte absolute count as a reference method, 34 (23.4%) cases of regenerative anemia were identified. The findings indicated that RBC indices and RBC morphology did not align in evaluating medullary regeneration and that there is a good degree of agreement between RBC morphology assessment and the reticulocyte absolute count in identifying regenerative anemias. Blood smear analysis of RBC morphology was more dependable for classifying regenerative anemia than RBC indices. Further studies should be conducted with a larger number of animals and that allow the identification of the cause of anemia and the monitoring of the animal.

Congenital Dyserythropoietic Anaemia Type II with SEC23B Mutation in Adults: A Case Series

МАТЕМАТИЧЕСКОЕ МОДЕЛИРОВАНИЕ В ДИФФЕРЕНЦИАЛЬНОЙ ДИАГНОСТИКЕ АНЕМИИ ХРОНИЧЕСКИХ ЗАБОЛЕВАНИЙ И ЖЕЛЕЗОДЕФИЦИТНОЙ АНЕМИИ У ПАЦИЕНТОВ С ВОСПАЛИТЕЛЬНЫМИ ЗАБОЛЕВАНИЯМИ СУСТАВОВ

Aim. To develop based on the indicators of clinical blood tests, some biochemical markers, iron metabolism and cytokines a mathematical model that allows with high sensitivity and specificity to conduct differential diagnosis of anemia of chronic diseases (AHD) and iron deficiency anemia (IDA) in patients with inflammatory joint diseases (rheumatoid arthritis (RA), psoriatic arthritis (PSA), ankylosing spondylitis (AS)). Material and methods. The study included 104 patients with inflammatory joint diseases and anemic syndrome (37 males/67 females, age 48.4±5.42 years old), of which 54 patients with RA, 27 patients with PSA and 23 patients with AS. The control group consisted of 22 patients with inflammatory diseases of the joints without anemia (13 males/9 females, age 47.8±3.55 years old), of which 7 patients with RA, 10 with PSA, 5 with AS. For all patients, in addition to hemogram parameters, the concentrations of interleukin-6, interleukin-10, interleukin-1β, interferon-gamma, tumor necrosis factor alpha, ferritin, C-reactive protein, hepcidin, transferrin, soluble transferrin receptor were determined. For quantitative indicators, the median, standard error of the mean, and interquartile range was calculated. The significance of differences between several unrelated groups was determined using the Kruskal-Wallis test. The calculation of a mathematical model for the differential diagnosis of ACD and IDA was carried out using discriminant analysis. Results. As a result of the study, a canonical linear discriminant function (CLDF) was obtained: CLDF = 1.612171-0.002725× Hepcidin -0.005429× Ferritin The coordinates of the centroids are calculated, for ACD it is -1.44222008, and for IDA it is 1.52705656. A patient whose CLDF value is determined based on ferritin and hepcidin concentrations should be classified into the ACD or IDA group based on the minimum distance to the corresponding centroid. The resulting mathematical model has 100% sensitivity and 80% specificity. Conclusions. The equation based on hepcidin and ferritin (obtained from the results of discriminant analysis) allows, with high sensitivity, specificity and information ability, to carry out differential diagnosis of ACD and IDA in patients with inflammatory joints diseases instantly at the stage of initial contact with the doctor. Using of the equation will make it possible to more effectively diagnose and correct these types of anemia in this pathology, including for the purpose of more effective treatment.

Mean corpuscular volume changes in different conditions

mean corpuscular volume (MCV) informs a lot about condition of the human body including directly or indirectly signaling about plethora disorders as erythrocytes being an oxygen carrying cells by its indicators’ changes elucidate oxygen content status of the organism. The erythrocytes index parameters particularly MCV can be indicative of the result of the many conditions. In current review the data about MCV variations, namely macro- and microcytosis are systematized and analyzed in further three groups: while physiological conditions of human body (age, sex, pregnancy), in different diseases (variety types of anemias, kidney disorders, endocrine system pathology, cardiovascular disorders, chronic obstructive pulmonary disease) including under the treatment of the latter (antiretroviral treatment of HIV, colorectal cancer, phlebotomy), and caused by iatrogenic influence (toxins, smoking, alcohol drinking). Current minireview includes mindful analysis of 20 trials published in PubMed database.

Unveiling the Antianemic Activity, Physicochemical Aspects, Antioxidant Properties, and Mineral Profile of Petroselinum crispum L.

Anemia is a widespread global health concern necessitating effective, accessible, and natural interventions. The potential of medicinal plants to address anemia has garnered significant interest. Among these plants, parsley (Petroselinum crispum (Petroselinum crispum) L.) stands out as an edible and herbal-based option for combating anemia. Aim of the study: This study investigated the potential of P. crispum (PC-Ext) as an emerging antianemic product, focusing on its physicochemical attributes, antioxidant properties, and mineral profile. Both qualitative and quantitative analyses of the phenolic compounds in P. crispum were conducted by using high-performance liquid chromatography with a diode array detector (HPLC-DAD). Anemia was induced in rats by intravenous injections of phenylhydrazine, administered at a dose of 40 mg/kg for two consecutive days. The antianemic activity of PC-Ext was assessed at a dose of 500 mg/kg twice daily for 5 weeks by estimating blood parameters, such as serum iron and ferritin. Additionally, the osmotic fragility test measured the capacity of red blood cells to withstand osmotic shock of various concentrations of saline. Aqueous extract of P. crispum was rich in phytochemical compounds, including syringic acid, quercetin, catechin, gallic acid, and luteolin. The findings demonstrate the effectiveness of P. crispum in ameliorating phenylhydrazine-induced reductions in red blood cell count (RBCs), hemoglobin (Hb), and hematocrit (HCT) levels. Consequently, PC-Ext exhibits significant activity against phenylhydrazine-induced anemia in rats, as demonstrated by its ability to prevent hemolysis. Iron estimation within PC-Ext further confirms its utility in addressing both iron deficiency and ferritin-deficiency anemia. Therefore, PC exhibits a favorable effect against both types of anemia, iron deficiency, and hemolysis. The results of this study provide robust scientific validation for ethnomedicinal use and the potential utility of P. crispum, positioning it as a promising source for future pharmaceutical development.

Expert consensus on clinical genetic counseling of α-thalassemia gene analysis

α-thalassemia is a type of microcytic hypochromic anemia caused by variants of alpha-globin gene, and is one of the most common monogenic disorders in southern China. The population screening model based on hematologic phenotype has achieved great results in areas with high incidence of thalassemia. However, with the continuous decline of the cost of genetic testing and implementation of screening programs for thalassemia gene carriers, more variants in the alpha-globin gene have been discovered, which also brings great challenges to clinical genetic counseling. From the perspective of alpha-globin genetic analysis, this consensus has discussed the contents of pre- and post-test genetic counseling, with an aim to provide standardized guidance for clinicians.

Morphology and ultrastructure of cicatricose spores found in an isolated sporangium-bearing structure of a schizaealean fern from the Lower Cretaceous rocks at Casal do Borracho, Torres Vedras, western Portugal

Fossil spores provide important insights into the evolutionary history of ferns, including their morphological changes and adaptations over time. The morphology and ultrastructure of trilete spores with cicatricose sculpture composed of sets of parallel or near-parallel ribs (muri) have been studied. Observations on the spores were performed using light microscopy, scanning electron microscopy, and transmission electron microscopy. The cicatricose spores were extracted from a single sporangium-bearing structure collected from Casal do Borracho mesofossil flora near Torres Vedras (Lusitanian Basin, western Portugal) from sediments belonging to the Almargem Formation, considered to be of late Barremian or early Aptian age (and possible younger than that). The sporangium-bearing structure of a schizaealean fern and in situ cicatricose spores are compared with the family Anemiaceae. On the basis of spore size and shape, laesura length, with about 20 proximal narrow ribs, oriented perpendicular to the spore sides, and three sets of distal ribs forming V-shaped patterns, the cicatricose spores in the present study are clearly assigned to the fossil-taxon Cicatricosisporites venustus. The spore ultrastructure includes a homogeneous exospore of a blechnoid type with a slight difference in the thickness in the proximal, distal, and equatorial regions. The morphology and ultrastructure of the studied spores are corresponded to Anemia type.

Expression of MiR-144/451 in Different Types of Anemia

To investigate the expression level and clinical correlation of microRNA-144/451 gene cluster (miR-144/451) in different types of anemia. The peripheral blood of patients with aplastic anemia (AA), myelodysplastic syndrome (MDS) and diffuse large B-cell lymphoma (DLBCL) who had been diagnosed with anemia for the first time and after chemotherapy were collected. The expression levels of miR-144 and miR-451 were measured by RT-qPCR, and the correlation between the expression levels of miR-144 and miR-451 and routine laboratory indexes was analyzed by Spearman correlation analysis. The expression levels of miR-144 and miR-451 in the peripheral blood of AA and MDS patients were significantly lower than those in normal controls (all P < 0.01). No statistical differences were observed in the expression level of miR-144 in three subgroups of DLBCL patients (P >0.05), while the expression level of miR-451 in peripheral blood of three subgroups of DLBCL patients were significantly higher than those in normal controls (all P < 0.05). Correlation analysis showed that the expression levels of miR-144 and miR-451 in AA patients were positively correlated with red blood cell distribution width-coefficient of variation (RDW-CV) (r =0.629, 0.574). There were no significant correlations between the expression levels of miR-144 and miR-451 and laboratory parameters in MDS and DLBCL patients. Different types of anemia disorders have varying levels of miR-144 and miR-451 expression, which is anticipated to develop into a secondary diagnostic and differential diagnostic indicator for clinical anemia diseases.

A Systematic Review of Symptoms of Pernicious Anemia.

Pernicious anemia (PA) is a type of macrocytic anemia caused by autoimmune gastritis. To facilitate timely diagnosis and treatment of PA there is a pressing need for improved understanding among Healthcare providers of the condition's symptoms and diagnostic criteria. This systematic review aims to extend existing clinical knowledge on the presentation of PA by determining which symptoms and clinical complications are reported in published adult case studies. Relevant studies were identified through electronic searches of PsycINFO, Embase, and MEDLINE, via OvidSP. During data extraction symptoms were categorized according to the International Classification of Diseases and were grouped based on frequency. Symptoms were documented for 103 adults with a diagnosis of PA; the most frequent symptoms were fatigue (55%), loss of sensation in limbs (32%), excessive weight loss (27%), and a sore tongue (23%). This review highlights the diverse symptomology of adults who are diagnosed with PA. Most symptoms documented in case studies are consistent with the core signs of B12 and folate deficiencies. Research is needed to identify if there are common clusters of PA symptoms that can be used as prompts for diagnostic testing in patients with suspected B12 deficiency.

Clinical management of iron deficiency anemia in Japan: iron prescription patterns, treatment effectiveness, and assessments

Iron deficiency anemia is one of the most common types of anemia, but real-world clinical management practices in Japan are unclear. This study retrospectively explored iron prescription patterns, treatment effectiveness, and assessments. Patients with at least one treatment period between September 2020 and September 2022 were included and classified into three groups (ferric carboxymaltose [FCM]: 7437 patients, saccharated ferric oxide [SFO]: 98,648 patients, and oral iron: 359,547 patients). Iron-related laboratory values over time and testing proportions were evaluated. Median baseline hemoglobin levels were lowest with FCM (FCM: 8.10 g/dL, SFO: 8.70 g/dL, oral iron: 9.70 g/dL), but changes in hemoglobin levels by 12 weeks were greatest with FCM (FCM: 3.20 g/dL, SFO: 2.60 g/dL, oral iron: 1.70 g/dL). The median serum ferritin level at 8 weeks after FCM treatment was 43.70 ng/mL for ≤500 mg, versus 123.30 ng/mL for >500 to ≤1500 mg. All groups had a low proportion of serum ferritin and transferrin saturation (TSAT) testing at diagnosis (<38%), which decreased further for post-treatment assessment (<24%). This study suggests the importance of prescribing an appropriate total iron cumulative dose per the package insert, along with diagnosis and assessments based on serum ferritin/TSAT.

Anemia and associated factors among under-five children attending public Hospitals in Harari Regional State, eastern Ethiopia: A cross-sectional study.

Childhood anemia is a significant global public health problem. It influences the physical and cognitive development, as well as immunity of affected children. This in turn leads to poor academic performance, low working potential, and increased morbidity and mortality. There is limited facility-based data on the magnitude and predictors of anemia among under-five children. This study aimed to determine the prevalence and associated factors of anemia among under-five children attending public Hospitals in Harari Regional State, eastern Ethiopia. Institution-based cross-sectional study was conducted at Hiwot Fana Comprehensive Specialized University Hospital and Jugal Hospital from July 1, 2022, to August 31, 2022. A total of 330 under-five children were involved by systematic random sampling technique. Data on sociodemographic characteristics and other possible factors were collected through face-to-face interviews with children's parents/legal guardians. Four milliliters of venous blood samples were collected for a complete blood cell count. Collected data were checked for completeness, entered into Epi-Data Statistical Software Version 4.6, and exported into the Statistical Package for Social Sciences version 25 for analysis. Bivariable and multivariable logistic regression was conducted and P < .05 were considered statistically significant. The overall prevalence of anemia was 33% (95% confidence interval [CI]: 27.9%-37.9%). Age of children 6 to 11 months (adjusted odd ratio [AOR] = 3.94, 95% CI: 1.55-10.01) and 12 to 23 months (AOR = 2.93, 95% CI: 1.15-7.43), no maternal education (AOR = 4.34, 95% CI: 1.53-12.35), not exclusively breastfeeding (AOR = 1.98, 95% CI: 1.11-3.52), being severely stunted (AOR = 3.39, 95 CI: 1.70-6.75), and underweight (AOR = 2.1, 95% CI: 1.12-3.87) were significantly associated with anemia among under-five children. In this study, anemia among under-five children is a moderate public health problem. This study revealed that young child age, maternal education level, early initiation of complementary feeding, and child undernutrition were factors associated with anemia. Thus, efforts should be made to improve the child's nutritional status as well as enhance maternal awareness of nutrition and child-feeding practice through health education. Regular childhood nutritional screening and appropriate intervention for malnutrition are needed. Besides, further studies assessing serum micronutrient levels should be conducted to differentiate the specific cause and type of anemia.
