Intestinal Parasites and Hematological Parameters in Children Living in Ambatoboeny District, Madagascar

Madagascar is one of the poorest countries in the world. The country’s extreme weather conditions, poor sanitation, and weak economy facilitate the spread of parasitic diseases. Infections with intestinal parasites are particularly dangerous for children because they can cause malnutrition and anemia, which, in turn, have a negative effect on children’s cognitive functions and physical development. The aim of the present study was to analyze the prevalence of intestinal parasites and to assess hematological parameters in a group of children living in northern Madagascar. The screening was conducted in May 2024 in the Clinique Medicale Beyzym in Manerinerina, the Ambatoboeny district. It involved a sample of 208 children aged 0–17 years. Single stool samples were collected from all study participants. The samples were fixed in SAF fixative and then transported from Africa to Europe for further diagnostics at the Department of Epidemiology and Tropical Medicine, the Military Institute of Medicine–the National Research Institute in Poland. First, the samples were analyzed by light microscopy methods using three different diagnostic techniques (direct smear, decantation with distilled water, and the Fülleborn method). Next, they were tested by molecular biology methods (real-time PCR). Blood samples for the assessment of hematological parameters were collected at the healthcare center in Madagascar. The prevalence of intestinal parasites in the study sample was 61.5%. Helminths were found in 15.2% of the investigated children, and Giardia intestinalis (20.5%) was found to be the most prevalent parasite in the study population. Most infections were caused by potentially pathogenic stramenopila Blastocystis spp. (32.0%). Mean Hb, HCT, MCV, MCH, and MCHC levels in the study participants were below normal values. However, no correlation was found between the presence of a parasitic infection and low hematological parameters, which are a clinical sign of anemia. High rates of infections with intestinal parasites in children living in northern Madagascar support the necessity to introduce long-term preventive measures, which would limit the spread of parasitic diseases in the Malagasy population. Low hematological parameters in non-infected children may be indicative of persistent malnutrition or infection with other parasites, e.g., malaria or schistosomiasis.

Subacute Toxicity and Pharmacokinetic Evaluation of the Synthetic Cannabinoid 4F-MDMB-BUTINACA in Rats: A Forensic and Toxicological Perspective

Background: 4-MDMB-BUTINACA, a next-generation synthetic cannabinoid, presents significant public health and forensic challenges due to its evolving nature and potential toxicity. Methods: This study evaluates the subacute toxic effects and pharmacokinetics of 4−Fluoro MDMB−BUTINACA (4F-MDMB-BUTINACA) in adult male albino rats, administered orally for seven days at doses of 1 mg/kg, 5 mg/kg, and 15 mg/kg. The hematological, biochemical, and histopathological parameters were assessed and compared to controls. Results: The pharmacokinetics were determined using GC–MS/MS with a positive chemical ionization and granisetron as an internal standard. A histological analysis revealed inflammatory cell aggregation, congestion, hemorrhage, edema, and fibrosis in various tissues, with renal examinations showing tubule degradation, glomerular atrophy, Bowman’s space expansion, edema, and hemorrhage. The liver exhibited cellular infiltration, while cardiac muscle fibers showed myocardial fiber degradation and inflammatory cell aggregation. Biochemical assays indicated significant alterations (p < 0.05) in the serum levels of AST, ALT, ALP, GGT, total protein, albumin, triglycerides, urea, MCHC, MCV, RDW, platelets, neutrophils, eosinophils, and basophils compared to the controls. Conclusions: The validated bioanalytical method revealed rapid absorption of 4F-MDMB-BUTINACA, with a plasma half-life of 2.371 h, a volume of distribution of 2272.85 L, and a plasma clearance rate of 664.241 L/h. In conclusion, 4F-MDMB-BUTINACA is a highly toxic synthetic cannabinoid, particularly affecting the liver, kidneys, and heart.

Anemia on Chronic Disease in Leprosy Before and After Completing Multi Drug Therapy

Leprosy infection can cause anemia due to chronic disease (ACD). Multidrug therapy (MDT) for leprosy patients can overcome the infection. This study aims to determine the comparison in the incidence of ACD before and three months after MDT to leprosy patients at Prof. Dr. I G.N.G. Ngoerah Central General Hospital. A cross-sectional analytical observational study was conducted using secondary data from medical records of leprosy patients. A total of 142 samples were taken through total sampling. Data taken included gender, domicile, type of leprosy suffered, incidence of ACD, hemoglobin levels, and erythrocyte index before and three months after completing MDT leprosy therapy. Data analysis was carried out with SPSS version 21 using chi-square and paired t tests (dependent t-test), p value <0.05 means significant. The incidence of ACD was significantly higher before leprosy MDT therapy compared to 3 months after completing leprosy MDT therapy (49.3% vs. 16.2%; p value <0.001) with a prevalence ratio of 3.043 (2.021-4.584) CI95%. The mean hemoglobin levels, MCV, MCH, and MCHC levels 3 months after MDT leprosy therapy were significantly higher than before receiving MDT therapy (13.73 ± 1.47 vs. 12.40 ± 2.06 g/dL; p value <0.001), (88.18±7.22 vs. 84.07±9.55 fl; p value<0.001), (28.32±2.76 vs. 26.72±3.17 pg/cell; p value <0.001), (32.03±1.30 vs. 31.69±1.47%; p value<0.001). The incidence of ACD was significantly higher before MDT compared to 3 months after MDT. Mean hemoglobin, MCV, MCH, and MCHC levels were found to be significantly higher 3 months after MDT compared to before receiving MDT.

Analysis of Erythrocyte Parameters in Multiple and Long-Term Blood Donors from Northern Pomerania (Poland)

Background/Aims: Assessment of the levels of vital blood parameters in donors is essential to evaluate their health status, ensure their suitability for donation, preserve the integrity of the circulatory system, and facilitate comprehensive health monitoring. The aim of our study was to analyse the levels of haemoglobin, haematocrit, erythrocyte count, MCV, MCH, and MCHC in 12 groups of first-time donors and experienced donors of both sexes at the John Paul II Regional Blood Donation and Treatment Centre in Słupsk, northern Poland. The donors were divided into three age groups (18-30 years, 31-45 years, and 46-65 years). Methods: Using MANOVA multivariate significance tests, we examined the main effects of donor-related factors (age, sex, donor stage) on morphological blood parameters to evaluate different haematological parameters, such as Hb, Ht, RBC, MCV, MCH, and MCHC, and identified statistically significant relationships between all variables. Results: The multivariate analysis of these three main factors showed that the variation in haemoglobin (Hb) levels accounted for 46% of the explained dependence in this statistical model. In particular, approximately half of the variability in the multivariate statistical analysis was attributed to the role of Hb and haematocrit (Ht). In addition, the β-coefficient values for Hb and Ht were statistically higher in relation to donor sex and donor type (single versus repeat). These β-coefficient values from our data represent the strength and direction of the relationship between the haematological parameters (Hb and Ht) and the specific donor characteristics. A higher β-coefficient indicates a stronger influence of donor sex and donor type on these parameters, suggesting that these factors contribute significantly to the variation in the Hb and Ht levels. Based on our results, the comprehensive analysis of the entire statistical model of metabolic biomarkers revealed the following hierarchy: Hb > Ht > MCHC > MCV > RBC > MCH. The results obtained showed strong statistical relationships, as indicated by the high values of the key statistical indicators in our analysis. The coefficient of determination (R²) showed that the model explained a significant proportion of the variance in the data, while the F-test statistic confirmed the significance of the predictors. Conclusion: These strong statistical dependencies provided a clear justification for selecting this model over others, as it effectively represented the underlying relationships within the data. These statistics help to assess how well the model matches the actual data, thereby helping to reduce the risks associated with blood donation, optimise donor safety, and maintain the quality and efficiency of blood transfusion services.

Dietary Effects of Black-Oat-Rich Polyphenols on Production Traits, Metabolic Profile, Antioxidative Status, and Carcass Quality of Fattening Lambs

The study aimed to establish the dietary effects of black oat rich in polyphenols on the production traits, metabolic profile, antioxidant status, and carcass quality of fattening lambs, after weaning. In the BO group, in the feed mixture, common oats replaced the black oat compared to the CO group. The research comprehensively investigated production indicators, blood metabolic profile, antioxidant status, and lamb carcass quality. No significant differences were found in the fattening or slaughter characteristics of lamb carcasses, except for lower pH1 values in BO lamb carcasses. Significant increases in RBC, HCT, and MCV levels as well as TP, ALB, and GLOB concentrations and GPx and SOD activities in the blood of BO lambs were found. The glucose and EOS content as well as the activity of the enzymes ALT and ALP were significantly lower in the blood of the BO group than in the CO group. In the liver, the DPPH activity was significantly higher in the BO lambs compared to the CO lambs. The observed changes in glucose, protein metabolism, and antioxidant status in the blood and tissues of lambs indicate that the use of polyphenol-rich black oats in the diet of lambs under stress conditions is justified.

The Correlation between Jordan's Iron Shortage, Vitamin D Status and Anaemia

Background: Both vitamin D and Fe micronutrient deficiencies are common in Jordan, but the association between them is unclear. Iron and vitamin D deficiencies are common disorders that cause a variety of health issues in the population. Objectives: The present study sought to elucidate the potential association between Vitamin D status and iron deficiency anemia in the Jordanian population. Method: The data of 207 persons over the age of 18 who sought periodic medical examinations at family medicine polyclinics were classified as iron deficiency, iron deficiency anemia (IDA), and 25 hydroxy vitamin D(25(OH)D) levels were classified as deficiency, insufficiency, and sufficiency. Serum 25-hydroxyvitamin D(25(OH)D), iron (fe), total iron-binding capacity (TIBC), c- reactive protein (CRP), and other parameters were assessed and compared across groups. Result: 41 participants (20.3 percent) were male (mean age = 40.24±12.79) and 167(79.7 percent) were female (mean age = 35.96±11.21). The number of IDA patients was 62(30%), whereas the number of patients without anemic symptoms was 145. (69.7percent). The mean 25(OH)D levels in individuals with IDA were found to be considerably lower (15.96ng/mL) than in those without (27.85ng/mL) (p-values are 0.001). The mean Hgb, RBCs, Hct, MCV, MCH, MCHC, TIBC, iron, and ferritin levels in the 25(OH)D adequate group were significantly greater than in the deficient and insufficient 25(OH)D groups (P-value 0.0001). The Pearson correlation analysis revealed that the examined parameters, which included Age, HGB, PCV, RBC, MCV, MCH, MCHC, Ferritin, Fe, TIBC, Vitamin D, CRP, and gender, had a positive relationship. Conclusions: the association between vitamin D and ID/IDA was significantly recognized in addition to other factors related to iron. Larger studieswith the inclusion ofmarkers such as hepcidin, vitamin D metabolites may provide a clearer view of this complex association.

Antimicrobial characteristics of endophytic Aspergillus terreus and acute oral toxicity analysis

BackgroundEndophytic fungi produce biologically robust metabolites suitable for diverse applications, which support the increasing exploration of these fungi. The study aimed to investigate the in vitro antimicrobial properties of the metabolites of endophytic fungus Aspergillus terreus which isolated from the leaves of Psidium guajava plants while the acute oral toxicity was assessed in vivo. ResultsA. terreus (OR125572) was successfully isolated for the first time from P. guajava. The ethyl acetate extract of A. terreus exhibited antibactericidal effects against Enterobacter aerogenes with a minimum inhibitory concentration of 18.75 mg/ml in contrast to 75.00 ± 0.0, 37.50, and 37.50 mg/ml, respectively against Staphylococcus aureus, Escherichia coli, and Bacillus sphaericus were 75.00 ± 0.0, 37.50, and 37.50 mg/ml, respectively. Analysis of the crude extract obtained from A. terreus by GC-MS revealed a total of 32 distinct compounds. The major components included 1,2-benzenedicarboxylic acid, di-iso-octyl ester; hexyl oxecan-2-one and phenol. The acute oral toxicity study found no symptoms of toxicity and no mortality until the 14th d, suggesting that the LD50 value of A. terreus extract might exceed 1 ml/kg. The group receiving 0.5 ml/kg of A. terreus extract experienced a 42.9% increase in body weight, while administration of varying dosages resulted in a significant reduction in MCV levels. There was also a significant increase in the proportion of monocytes across all treated groups. ConclusionsThe study demonstrated the potential of A. terreus as a source of antimicrobial and other bioactive compounds, with relatively low acute toxicity.How to cite: Shehabeldine AM, Abdelaziz AM, Abdel-Maksoud MA, et al.

Iron status and anemia as predictors for acute bronchiolitis severity

BackgroundThe aim of this study was to determine the effect of iron deficiency anemia (IDA) on the severity of symptoms in infants hospitalized for acute bronchiolitis.MethodsThis is a case–control study, which was carried out on 80 infants from November 2022 to April 2023. The study involved 60 infants ranging in age from 2 months to 2 years, who were admitted to the Pediatric Pulmonology Unit and met the diagnostic criteria for acute bronchiolitis. Furthermore, a control group of 20 apparently healthy infants was incorporated into the study.ResultsThis study showed that patients with moderate and severe bronchiolitis exhibited notably reduced levels of hemoglobin, HCT, MCV, MCH, and MCHC. Concerning the iron status, a substantial decrease in serum iron and increase in TIBC in the severe group (P = 0.012, 0.001, respectively). No substantial correlation was detected between the severity of acute bronchiolitis and serum ferritin levels. Hemoglobin and serum iron were found to be independent predictors of the severity of acute bronchiolitis.ConclusionsInfants suffering from IDA exhibit increased vulnerability to acute bronchiolitis. The low levels of hemoglobin and serum iron may function as prognostic indicators for the severity of the condition in infants with acute bronchiolitis.

Post-COVID-19: Hematological Factors Changes in Patients at Three-- time Intervals.

Hematological parameters are crucial factors in disease severity and chronic condition pathogenesis. We aimed to evaluate the hematological factors in different severity stages of COVID-19 at different time intervals. Serum samples were collected from 470 patients (235 men and 235 women) with a confirmed RT-qPCR COVID-19 test exhibiting moderate, severe, and critical symptoms based on WHO criteria. Samples were collected at three-time intervals, including the first: the 1st days of infection, 2nd: the one month after, and 3rd: the three months after disease onset. Total WBC, neutrophil, lymphocyte, monocyte, eosinophil, RBC counting, Hb, HCT, MCV, MCH, MCHC, hsCRP levels, G6PD deficiency, and hemoglobinopathies were determined in all patients. Total WBC, neutrophil, lymphocyte, platelet, RBC counting, Hb, HCT, MCV, MCH, and hsCRP levels were significantly changed with different disease severity (p&#60;0.0001). Also, there were significant differences between different time intervals for WBC and RBC parameters (p&#60;0.0001) except for monocytes and eosinophils. At all time intervals, there are significant changes in levels of hematological and hsCRP based on gender. Moreover, a significant correlation was observed between disease severity, age, and BMI (p&#60;0.0001). Significant differences in hematological parameter and inflammatory parameter levels based on disease severity, time intervals, and gender revealed the importance of evaluating these factors in the management of infectious diseases, such as COVID-19, in patients during and post-disease times.</p>.

#2275 Beyond glucose control: SGLT2 inhibitors' impact on hematological parameters in lupus nephritis patients

Abstract Background and Aims There is a broad spectrum of hematologic manifestations in SLE including lymphopenia, anemia, thrombocytopenia, or pancytopenia. Anemia worsens the prognosis of many chronic diseases including lupus nephritis. A recent systematic review and metanalysis showed that hemoglobin and hematocrit levels were significantly increased with SGLT2i therapy when compared to placebo. This study aimed to investigate the effect of SGLT2 inhibitors on hematological parameters including iron profile, hepcidin and erythropoietin levels in lupus nephritis patients. Method Double blind randomized controlled trial. The material of the current study included 79 Lupus nephritis patients who were recruited from Nephrology clinic- Urology and Nephrology Center- Mansoura University. Patients with an estimated glomerular filtration rate (eGFR) &amp;gt;30 ml/min/1.73 m2 had been randomly assigned to 2 groups Study group: included 38 lupus nephritis patients who were randomly assigned to receive dapagliflozin (10 mg once daily) Placebo group: included 41 lupus nephritis who were assigned to receive placebo. The two groups were randomly assigned using computer-generated random tables in a 1:1 ratio and followed up for 12 months. The findings were recorded, tabulated, and analyzed using SPSS22 for windows. Results Both groups had similar ages and gender distribution. BMI, diabetes mellitus, and hypertension rates were comparable between groups. The duration of lupus nephritis and management approaches did not differ. Biopsy results indicated no differences in the class of lupus nephritis. Serum chemistry, including serum creatinine, was similar between groups. The mean hemoglobin levels, MCV and MCH are similar between the control and study groups, with no statistically significant difference (p = 0.5, 0.9 and 0.9 respectively). Regarding iron indices, the median ferritin, TSAT levels show a numerical difference, but it does not reach statistical significance (p = 0.09, 0.05), The mean erythropoietin and hepcidin levels are not significantly different between the groups (p value= 0.1 and 0.9 respectively) also, platelet counts are similar between the groups (p = 0.7). compares hematological investigations before and after the intervention in the study group. There is a statistically significant increase in mean hemoglobin levels post-intervention compared to baseline (p = 0.02) and the mean MCH levels show a numerical increase post-intervention, but the difference is not statistically significant (p = 0.1), but the mean MCV levels do not show a statistically significant change post-intervention (p = 0.7). The median ferritin levels and TSAT values show a numerical increase post-intervention, but the difference is not statistically significant (p = 0.8 and 0.9 respectively). There is a statistically significant decrease in mean hepcidin levels post-intervention (116 ± 15 from baseline 181 ± 76) and (p = 0.001). erythropoietin levels show a numerical increase post-intervention, but the difference is not statistically significant (p = 0.1). there is a slight decrease in platelets counts after intervention but make statistically significant (p = 0.01), but The hematological data after 12 months suggest overall similarity between the control and study groups in terms of hemoglobin, MCV, MCH, ferritin, TSAT, and platelet count, also hepcidin and erythropoietin levels were comparable between both groups (P = 0.7). percentage of participant with anemia (Hgb&amp;lt; 12 g/dl) decreased in study group after intervention from 61% to 42% but with no significant difference with control group (p = 0.3) Conclusion Anemia in lupus nephritis patients is primarily due to iron deficiency, associated with elevated hepcidin levels. Further research is needed to explore these patients' underlying causes of anemia. SGLT2 inhibitors are important add on drugs that has positive effect on varies hematological parameters in lupus nephritis patients in addition to their renal benefits.

Anemia among Medical Students from Jakarta: Indonesia-Iron Deficiency or Carrier Thalassemia?

Anemia, a global health concern, affects one-fourth of the global population, particularly women. In Indonesia, its prevalence is 23.7%, with 32.0% among 15-24 year-olds. Factors include poor nutrition, infectious diseases, chronic diseases, inherited disorders, and inadequate healthcare access. This study aimed to investigate anemia prevalence and its etiology among medical students from Jakarta. This study was a descriptive research with a cross-sectional approach. Undergraduate students aged 18-23 years old were selected and consented to participate by a consecutive nonrandom sampling methods. Laboratory blood data were evaluated (including Hb, MCV, MCH, HbA2, and ferritin levels) and DNA was isolated to confirm the type of thalassemia carrier. In total, 140 medical students, mainly female, were recruited. Anemia was found in 13.6% (11.4% had low MCV and/or MCH), and 16.5% had low MCV and/or MCH without anemia. Hb electrophoresis revealed high HbA2 values, suggesting the HbE variant (2.1%), and β-thalassemia carrier (0.7%). DNA analysis confirmed the cd26 mutation and heterozygous IVS1nt5. Among those without anemia, 5% had α-deletion, while in the group with anemia, 1.4% had α-deletion (with coexistent IDA), 3.6% had α-deletion, and 0.7% had β-mutation. DNA analysis can identify specific mutations associated with alpha-thalassemia, distinguishing between iron deficiency anemia and the alpha-thalassemia trait. Thalassemia screening should involve low MCV and/or MCH values as the first step (stage 1), followed by Hb analysis (stage 2) and DNA analysis (stage 3). In common areas, a combination of Hb and DNA testing is best. However, healthcare professionals must diagnose and treat thalassemia, as proper management relies on accurately identifying the underlying condition.

Effect of Stocking Density, Multispecies Probiotics, and Biofloc on Metabolic and Physiological Responses of Puntius sophore in Laboratory Conditions

A 60-day experimental trial was conducted to evaluate the effect of different stocking densities, probiotic supplementation, and a biofloc system on the growth and physiological responses of Puntius sophore in laboratory conditions. P. sophore (8.64 ± 1.24 g) was obtained from the Brahmaputra River, Mymensingh, and immediately transferred to a flow-through water system. In experiment 1, fish were subjected to three treatments (20 fish per 400 L as LD, 25 fish per 400 L as MD, and 30 fish per 400 L as HD), and similarly, in experiment 2, three different types of diets were provided (control diet (D1), biofloc (D2), and a probiotic-containing diet (D3)). Three replications were used in the completely randomized experimental design. Growth parameters, viz. TLG, BWG, FCR, FCE, SGR, RGR, and DGR, were significantly influenced by stocking density and probiotics (p &lt; 0.05). The highest growth rate was observed in LD and in D3. The lowest FCR was also observed in LD and in D3, while highest was in HD (30 fish per 400 L) and in D2. Though stocking density does not impact the blood profile, with the exception of WBC, in the case of feeding regime, WBC, RBC, MCV, MCH, and PLT levels differed significantly (p &lt; 0.05); however, all haematological measures were within the normal range in both experiments, and the fish’s physiological conditions were better in LD and feeding with probiotic supplementation (D3). The results obtained from this study suggested that the welfare of P. sophore is adversely affected by high stocking density and increased growth and physiological conditions when cultured with LD and supplemented with probiotics.

Association between Red cells distribution width and glycemic control among people with type 2 diabetes.

Objective: To evaluate Red blood cell distribution width (RDW) in people with type 2 diabetes and its relationship with glycemic control. Study Design: Retrospective study. Setting: Baqai Institute of Diabetology and Endocrinology, Baqai Medical University. Demographic, Clinical and Biochemical Data were retrieved from hospital management system of BIDE. Period: September 2018 to April 2019. Material &amp; Methods: Ethical approval was obtained from the Institutional Review Board of BIDE. Based on the HbA1c values, patients were divided into two groups, HbA1c &lt; 7.0% and HbA1c ≥ 7.0%. RDW calculated from RBC histogram in Nihon Kohden fully automated analyzer. Results: RDW found 13.9±1.88 and 13.57±1.64 (p-value 0.018) in good and poorly controlled glycemic groups respectively. Poor glycemic group had higher levels of white cell count (9.58±4.34) and Triglycerides (170.12±129.13) (p-value &lt;0.05), whereas controlled glycemic group demonstrated higher levels of BMI (29.03±6.01), MCV (84.36±7.81) and HDL (33.75±12.31). RDW was directly correlated with gender (p-value &lt;0.0001) and duration of diabetes (p-value 0.01), and showed significant and inverse correlation with HbA1c. Age, blood pressure, duration of diabetes, serum LDL cholesterol, and the CBC values demonstrated no significant differences between the both groups. Conclusion: We found significant correlation between RDW and glycemic control.

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.

Genetic epidemiology of thalassemia in couples of childbearing age: over 6 years of a thalassemia intervention project.

Shenzhen is one of the most populated metropolises in southern China where thalassemia is highly prevalent. The prevention of thalassemia inheritance is an ambition of child-bearing couples. A total of 22,098 peripheral blood samples were collected from 11,049 potentially at-risk couples of childbearing age from Shenzhen. Thalassemia mutations were determined by PCR-based flow-through hybridization. The results identified 45.02% of the participants (9948 out of 22,098) as harboring globin gene mutations, distributed into 18 α-thalassemia alleles detected in 71.48% (7111 out of 9948) and 15 β-thalassemia alleles detected in 32.68% (3252 out of 9948) of all mutant individuals, among which 415 individuals carried both α- and β-thalassemia alleles. The most frequent phenotypes for α-globin variations were --SEA/αα (63.37%), -α3.7/αα (18.66%), and -α4.2/αα (7.31%), and those for β-globin variations were β41-42/βN (34.96%), β654/βN (28.11%), and β17/βN (13.84%). A total of 970 high-risk couples who could possibly give birth to offspring with thalassemia intermedia or major were identified. In addition, the hematological indices were compared among thalassemia genotypes. Significant differences in MCH, MCV, Hb A, and Hb A2 levels among α-thalassemia minor (α+), trait (α0), and intermediate phenotypes (P < 0.05) and between βE/βN and the other β-thalassemia phenotypes (P < 0.05) were found. Moreover, GAP-PCR and next-generation sequencing further identified 42 rare mutations, 13 of which were first reported in the Chinese population. A novel mutation in the β-globin gene (HBB: c.246C > A (rs145669504)) was also discovered. This study presented a comprehensive analysis of thalassemia variations in a population from Shenzhen and may offer valuable insights for thalassemia control and intervention strategies in this area.

The association between admission mean corpuscular volume and preoperative deep venous thrombosis in geriatrics hip fracture: a retrospective study

ObjectiveThis study evaluated the association between admission MCV and preoperative deep vein thrombosis (DVT) in geriatric hip fractures.MethodsOlder adult patients with hip fractures were screened between January 2015 and September 2019. The demographic and clinical characteristics of the patients were collected at the largest trauma center in northwest China. MCV was measured at admission and converted into a categorical variable according to the quartile. Multivariate binary logistic regression and generalized additive model were used to identify the linear and nonlinear association between MCV and preoperative DVT. Analyses were performed using EmpowerStats and the R software.ResultsA total of 1840 patients who met the criteria were finally enrolled and divided into four groups according to their MCV levels. The mean MCV was 93.82 ± 6.49 (80.96 to 105.91 fL), and 587 patients (31.9%) were diagnosed with preoperative DVT. When MCV was a continuous variable, the incidence of preoperative DVT increased with mean corpuscular volume. In the fully adjusted model, admission MCV was positively correlated with the incidence of preoperative DVT (OR: 1.03; 95% CI: 1.01–1.05; P = 0.0013). After excluding the effect of other factors, each additional 1fL of MCV increased the prevalence of preoperative DVT by 1.03 times as a continuous variable.ConclusionMCV was linearly associated with preoperative DVT in geriatric patients with hip fractures and could be considered a predictor of DVT risk. The MCV may contribute to risk assessment and preventing adverse outcomes in the elderly.Study registrationThis study is registered on the website of the Chinese Clinical Trial Registry (ChiCTR: ChiCTR2200057323).

Relationship between tobacco smoking and hematological indices among Sudanese smokers

BackgroundTobacco Smoking is one of the leading causes of preventable morbidity and mortality in the world. It is well documented that tobacco smoking is risk factor for many diseases like: cancers, chronic respiratory and cardiovascular diseases, and the effects of tobacco smoking on hematological indices gets a little attention: the data is mostly inconsistent regarding the differential of WBCs, a conflicting studies described the effect of smoking on hemoglobin descriptive parameters and a regular monitoring of platelets count in smokers was advised.ObjectivesThe study aimed to evaluate the relationship between tobacco smoking and hematological parameters among Sudanese healthy Smokers at Bahri Town.MethodsThis was a cross sectional study conducted during 2022 in Bahri town, Khartoum state. A total of 120 male subjects participated in this study. Of them, 60 healthy non-smokers participants (Control), and 60 age matched smokers who were smoking tobacco for a minimum of 1 year. Smokers group was divided into three major sub-groups with each group contains 20 subjects: Cigarettes smokers (CS), Water pipes (Shisha) smokers (WP) and both Cigarettes and water pipes (shisha) smokers (CSWP). Data was collected through questionnaire interviews and laboratory investigation. A sample of Five ml venous blood was taken for Complete blood count testing using Urite 3000 plus semi-automated hematology analyzer. Data were analyzed using SPSS version 25. Assocation between the variables were estimated and p value ≤ 0.05 was considered statistically significant.ResultsSmokers had significantly higher RBCs count (p = 0.017), Hb level (p < 0.001), WBCs count (p = .017), Neutrophils (p < 0.001), MCH (p = 0.029), MCHC (p < 0.001), RDW (p < 0.001), and PDW (p < 0.001) compared to the non-smokers. In contrast, non-smokers had higher MPV (p < 0.001) and MCV (p < 0.001) levels than smokers. Between the non-smokers and different subtypes of the smokers (CS, WP & CSWP), there were significant differences between the subgroups for all hematological parameters except for PLTs and lymphocytes count. CS had lower levels of MCV (p < 0.001), MCHC (p < 0.001), HCT (p = 0.036), and RDW (p < 0.001) compared to the non-smokers, while both cigarette and shisha smokers had the higher levels of neutrophils count (p < 0.001) and PDW (p < 0.001) compared to the non-smokers.ConclusionSmoking affects hematological parameters; smokers had significantly higher RBCs count, Hb level, WBCs count, Neutrophils, MCH, MCHC, RDW and PDW compared to the non-smoker group. WP smoking caused higher levels of RBCs, Hb, neutrophils, MCH and MCHC. PDW was high in smokers’ sub-groups compared to control group, while MPV was lower despite insignificant change In PLTs count.

Effect of the Addition of Moringa Oleifera Leaves on Reproduction, Hematological, Biochemical Parameters, and Milk Yield and Composition of Goats Under Arid Conditions of Siwa Oasis

The objective of the present study was to investigate the potential benefits of supplementing Moringa oleifera leaves on various aspects of Baladi goat health and productivity under arid conditions in Siwa Oasis. Specifically, the study aimed to assess the effects on hematological and biochemical parameters, milk production and composition, and reproduction. A total of 30 healthy Baladi goats, with an average weight of 19.70 ± 0.36 kg, were randomly assigned to two experimental groups: the control (C) group, which received a basal diet without Moringa oleifera leaves, and the treatment (T) group, which received the basal diet supplemented with Moringa oleifera leaves at a rate of 50 grams/doe/day throughout the experimental period. The findings revealed that feeding goats with Moringa oleifera leaves led to increased milk productivity compared to the control group. Specifically, milk yield and all milk components, except for ash, were significantly higher (P &lt; 0.05) in the Moringa-treated group. Moreover, the Moringa group exhibited significantly higher levels of Hb concentration, RBC, PCV, and MCV compared to the control group. However, there were no significant differences in MCH and MCHC between the two groups. Interestingly, the control group showed a significant increase in WBC compared to the Moringa group. In terms of biochemical parameters, the results demonstrated a decrease in cholesterol and urea concentrations in Baladi goats fed with Moringa oleifera leaves. Conversely, the Moringa group exhibited significantly higher levels of serum total protein, glucose, and albumin compared to the control group. Furthermore, supplementation with Moringa oleifera leaves significantly improved kidding and weaning rates, as well as litter size in Baladi goats and decrease of mortality rates. Overall, the findings suggest that incorporating Moringa oleifera leaves into the diets of Baladi goats can enhance reproductive performance, milk production and composition, without any negative effects on the haemato-biochemical profile.

Hematological abnormalities in chronic liver disease and their association with severity and types of chronic liver disease

This study aimed to assess the hematological abnormalities in CLD patients and to study the association of hematological abnormalities with type and severity of CLD. This study was conducted as a facility based cross-sectional study at tertiary care centre on confirmed cases of chronic liver disease. Detailed clinical history along with clinical examination findings were recorded. All patients were then subjected to investigations. Mean age of patients with CLD was 48.8±16.9 years and majority of patients were males (76%). Anemia was observed in 71% cases with CLD whereas leukocytopenia and thrombocytopenia were noted in 21% and 56% cases respectively. Mean MCV, MCH, serum bilirubin and iron were significantly higher in cases with alcoholic liver disease whereas TIBC was significantly lower in ALD cases as compared to NALD cases (p&amp;#60;0.05). Mean hemoglobin, platelet levels, MCV, albumin and iron levels were significantly lower in cases with severe liver disease (Child Pugh Class C). However, serum bilirubin, prothrombin time and TIBC levels increased significantly with increase in severity of CLD (p&amp;#60;0.05). Hematological abnormalities particularly normocytic normochromic anemia and thrombocytopenia are common in cases with CLD, which might affect the prognosis of patients with CLD. Assessing the severity and type of anaemia is a useful tool for early initiation of the treatment in patients of CLD for reducing the morbidity and mortality. Early detection and treatment of haematological changes can prevent complications and reduce the mortality in CLD patients.

Efficacy of polysaccharide iron complex in IDA rats: A comparative study with iron protein succinylate and ferrous succinate

Iron deficiency anemia (IDA) is the most common nutrient-related health problem in the world. There is still a lack of comprehensive comparative study on the efficacies of commonly used iron supplements such as polysaccharide iron complex (PIC), iron protein succinylate (IPS) and ferrous succinate (FS) for IDA. In this study, we compared the PIC, IPS and FS efficacies in IDA rats via intragastric administration. The results showed that the three iron supplements had similar efficacies. PIC/IPS/FS at a dose of 15 mg Fe/kg/d for 10 d increased the hematological and serum biochemical parameters to 2.15/2.12/2.18 (Hb), 1.71/1.67/1.69 (RBC), 2.10/2.11/2.12 (HCT), 1.26/1.22/1.22 (MCV), all 1.34 (MCH), 1.15/1.15/1.14 (MCHC), 1.94/1.82/1.91 (SF), 9.75/9.67/9.53 (SI), and 23.30/22.68/21.64 (TS) times, and reduced TIBC to 0.42/0.43/0.44 times, compared to untreated IDA rats. PIC performed slightly better than IPS and FS in restoring MCV level. Meanwhile, the heart, spleen and kidney coefficients reduced to 67%/74%/65% (heart), all 59% (spleen) and 87%/88%/88% (kidney), and the liver coefficient increased to 116%/115%/116%, compared to untreated IDA rats. The liver iron content was found to be more affected by IDA than the spleen iron content. PIC/IPS/FS at 15 mg Fe/kg/d increased organ iron contents to 4.20/3.97/4.03 times (liver) and 1.36/1.24/1.41 times (spleen) within 10 d compared to untreated IDA rats, and PIC-H and FS were slightly better than IPS in restoring spleen iron content. The results of this study can provide useful data information for the comparison of three iron supplements, PIC, IPS and FS.
