Clinical and hematological analysis of testicular torsion in children.

Purpose: Analyze the clinical manifestations, laboratory tests, and imaging data of testicular torsion to provide clinical insights for timely and accurate diagnosis and treatment of testicular torsion. Methods: A retrospective analysis was conducted on the clinical data of 67 pediatric patients suspected of testicular torsion, admitted and subjected to surgical exploration from June 2018 to June 2023. Based on whether the torsed testicle was excised during surgery, the patients were divided into orchiectomy group (40 cases) and orchidopexy group (27 cases). Combining clinical symptoms, signs, ultrasound examinations, and laboratory tests, the study aimed to summarize the influencing factors on the onset, diagnosis, and treatment of testicular torsion. Results: The clinical manifestations of all 67 pediatric patients were generally typical. Color Doppler Flow Imaging (CDFI) and surgical exploration were performed for all cases, and the results were consistent. Testicular color doppler ultrasound suggested reduced or absent blood flow, leading to surgical treatment in all cases. All patients had unilateral testicular torsion, with 46 cases (68.66%) on the left side and 21 cases (31.34%) on the right side. Intrafunicular torsion occurred in 60 cases (89.55%), while extrafunicular torsion occurred in 7 cases (10.45%). The onset distribution was as follows: 20 cases in spring, 16 cases in summer, 16 cases in autumn, and 15 cases in winter. Univariate analysis indicated significant statistical differences in age, degree of testicular torsion, duration of symptoms, NEUT, NLR, and occurrence of tunica fluid between the two groups of patients. Multivariate logistic regression analysis showed that the duration of symptoms and the occurrence of hydrocele were independent risk factors for determining testicular viability. Conclusion: Testicular torsion is more common in children and adolescents, with clinical manifestations including scrotal pain, scrotal redness and swelling, abdominal pain, nausea, and vomiting. In the early stages of testicular torsion, inflammatory markers in the blood increase, and preoperative ultrasound indicates hydrocele. This suggests that the testicle is in an early twisted state, with good viability and potential for preservation.

The Influence of Specific Pathogen-Free and Conventional Environments on the Hematological Parameters of Pigs Bred for Xenotransplantation.

Blood analysis plays a pivotal role in assessing the health of laboratory animals, including pigs. This study investigated the hematological profiles of transgenic pigs of the MGH breed for xenotransplantation, focusing on the effect of housing conditions on blood parameters. A cohort of pigs was longitudinally monitored from 6 to 18 months of age in both conventional and specific pathogen-free (SPF) environments. Red blood cells (RBCs), hemoglobin (HGB), and white blood cells (WBCs) were analyzed using standardized hematology analyzers. The results revealed that RBC and HGB levels were consistently higher in SPF-housed pigs. Notably, WBC counts were significantly lower in SPF-housed pigs, suggesting that reduced pathogen exposure under SPF conditions effectively diminished immune system activation. These findings raise a novel question as to whether distinct hematological parameters of specific and/or designated PF pigs would be advantages for the success of clinical xenotransplantation trials.

Clinical and Hematological Correlates of Hemolytic Anemia in Diabetic Foot Ulcer Patients: A Prospective Observational Study.

Background Diabetic foot ulcers (DFUs) are a significant complication of diabetes mellitus and are often accompanied by various complications including hemolytic anemia. However, the clinical and hematological correlates of hemolytic anemia in patients with DFU remain poorly understood. This prospective observational study aimed to investigate the clinical and hematological correlates of hemolytic anemia in patients with DFU and to elucidate the potential mechanisms underlying this complication and its impact on wound healing. Methodology A total of 148 adult patients diagnosed with DFUs were enrolled in this study. Clinical and demographic data were collected, including age, sex, duration of diabetes, glycemic control status, presence of comorbidities, and foot ulcer characteristics. Hematological parameters, including complete blood counts, reticulocyte counts, and hemolysis markers, were measured at baseline and during the follow-up visits. Statistical analyses were conducted to assess the prevalence of hemolytic anemia, identify the demographic and clinical factors associated with its presence, and explore its relationship with wound healing outcomes. Results The prevalence of hemolytic anemia among patients with DFU was 41.9%. Patients with hemolytic anemia had a longer duration of diabetes (mean duration: 8.3 ± 2.1 years), higher glycated hemoglobin (HbA1c) levels (mean: 9.2% ± 1.5%), and a greater burden of comorbidities than those without hemolytic anemia. Hematological analysis revealed significant differences in hemoglobin levels, red blood cell indices (mean corpuscular volume: 89.6 ± 5.2 fL), and markers of hemolysis (mean lactate dehydrogenase level: 325 ± 45 U/L) between DFU patients with and without hemolytic anemia. Furthermore, correlations were observed between hematological parameters and wound healing outcomes, suggesting potential implications for clinical management. Conclusions This study provides valuable insights into the clinical and hematological correlates of hemolytic anemia in patients with DFU. These findings highlight the importance of recognizing and addressing hematological abnormalities in the management of DFU, with potential implications for optimizing wound healing and improving clinical outcomes.

Predictive value of peri-chemotherapy hematological parameters for febrile neutropenia in patients with cancer.

Objective: The aim of this study was to compare hematological parameters pre- and early post-chemotherapy, and evaluate their values for predicting febrile neutropenia (FN). Methods: Patients diagnosed with malignant solid tumors receiving chemotherapy were included. Blood cell counts peri-chemotherapy and clinical information were retrieved from the hospital information system. We used the least absolute shrinkage and selection operator (LASSO) method for variable selection and fitted selected variables to a logistic model. We assessed the performance of the prediction model by the area under the ROC curve. Results: The study population consisted of 4,130 patients with common solid tumors receiving a three-week chemotherapy regimen in Sichuan Cancer Hospital from February 2019 to March 2022. In the FN group, change percentage of neutrophil count decreased less (-0.02, CI: -0.88 to 3.48 vs. -0.04, CI: -0.83 to 2.24). Among hematological parameters, lower post-chemotherapy lymphocyte count (OR 0.942, CI: 0.934-0.949), change percentage of platelet (OR 0.965, CI: 0.955-0.975) and higher change percentage of post-chemotherapy neutrophil count (OR 1.015, CI: 1.011-1.018), and pre-chemotherapy NLR (OR 1.002, CI: 1.002-1.002) predicted an increased risk of FN. These factors improved the predicting model based on clinical factors alone. The AUC of the combination model was 0.8275. Conclusion: Peri-chemotherapy hematological markers improve the prediction of FN.

Eligibility Criteria for Different Platinum-Based Chemotherapy Regimens in Metastatic Urothelial Carcinoma.

Introduction Bladder cancer is one of the most prevalent cancers worldwide, with significant morbidity and mortality rates. Treatment options for metastatic urothelial carcinoma (mUC) primarily include platinum-based chemotherapy. Cisplatin-based chemotherapy is conventionally used for treating mUC, but many patients are ineligible due to various factors such as poor performance status, creatinine clearance, neuropathy, and cardiac function. Carboplatin-based therapy is another alternative, which typically yields less favorable outcomes. Some centers use split-dose cisplatin for treating patients with comorbidities and impaired renal function, broadening cisplatin's spectrum. While eligibility criteria for full-dose cisplatin are well-established, those for split-dose cisplatin and carboplatin lack strong evidence. This study aims to assess the recommended criteria for full-dose cisplatin, split-dose cisplatin, and carboplatin regimens in real-world settings, including hematological parameters for patients with mUC. Methods  A cross-sectional web-based survey was conducted among 136 oncologists from 21 countries, assessing criteria such as creatinine clearance, Eastern Cooperative Oncology Group (ECOG) performance status (PS), neurotoxicity, hearing loss, heart failure classification, and hematological parameters. Results The survey revealed diverse preferences among 113 oncologists treating mUC, regarding the eligibility criteria for each chemotherapy regimen with 81% prioritizing full-dose cisplatin, 21% split-dose cisplatin, and 14% carboplatin regimens. Criteria for all three regimens included specific thresholds. For full-dose cisplatin, the preferred criteria included creatinine clearance ≥60 mL/min, ECOG PS ≤1, grade 1 neuropathy, grade 1 deafness, New York Heart Association (NYHA) heart failure ≤class II with ≥50% cardiac ejection fraction, and normal blood parameters. Split-dose cisplatin criteria were creatinine clearance ≥40 mL/min, ECOG PS ≤2, grade 1 neuropathy, grade 1 deafness, NYHA heart failure ≤class II with ≥50% cardiac ejection fraction, and normal blood parameters. Carboplatin eligibility criteria were creatinine clearance ≥30, ECOG PS ≤2, grade ≤2 neuropathy, grade ≤2 deafness, NYHA heart failure ≤class II with ≥50% cardiac ejection fraction, and normal blood parameters. Hematological parameters were deemed crucial for all regimens, particularly stringent for carboplatin-based chemotherapy. Conclusion The study underscores the importance of renal function and hematological parameters in determining chemotherapy eligibility for patients with mUC. It highlights the importance of precise treatment criteria in mUC management, with hematological factors playing a significant role. Standardized criteria and further research are warranted to optimize treatment outcomes and minimize adverse events associated with chemotherapy regimens. Understanding the preferences of oncologists globally can facilitate tailored treatment approaches and improve patient care in the management of mUC.

Age-Dependent Changes in Protist and Fungal Microbiota in a Peruvian Cattle Genetic Nucleus.

In this research, the connection between age and microbial diversity in cattle was explored, revealing significant changes in both protist diversity and fungal microbiota composition with age. Using fecal samples from 21 Simmental cattle, microbial communities were analyzed through 18S rRNA gene sequencing. Results indicated significant differences in alpha protist diversity among the three age groups, while fungal composition varied notably with age and was linked to hematological parameters. Despite the stability of fungal alpha diversity, compositional changes suggest the gut as a stable niche for microbial colonization influenced by diet, clinical parameters, and microbial interactions. All cattle were maintained on a consistent diet, tailored to meet the specific nutritional needs of each age group. These findings emphasize the importance of understanding age-related microbial dynamics to enhance livestock management and animal health, contributing to broader ecological and biomedical research. This study was limited by the lack of comprehensive metabolic analyses correlating microbiota changes with specific age-related variations, indicating a need for further research in this area.

Hematological Markers as Predictors of ICU Admission in COVID-19 Patients: A Case-Control Study From a Tertiary Hospital.

BACKGROUND: COVID-19 illness severity ranges from mild- to life-threatening cases necessitating critical care. Rapid prediction of disease severity and the need for critical care support in COVID-19 patients remain essential, not only for current management but also for preparedness in future pandemics. This study aimed to assess hematological parameters as predictors of intensive care unit (ICU) admission and survival in COVID-19 patients, providing insights applicable to a broad range of infectious diseases. METHODS: A case-control study was conducted at Hospital Raja Perempuan Zainab II, a tertiary referral hospital in Kelantan, Malaysia, from March 2020 to August 2021. Demographics, clinical, and laboratory data were retrieved from patients' medical records. Statistical analyses, including the Chi-square (χ2) test, independent t-tests, and simple and multiple logistic regressions, were used to analyze the data. A receiver operating characteristic (ROC) curve analysis was conducted to assess the accuracy of the predictors. RESULTS: The median age was 51 years, with females comprising 56.7% (n=148) and males 43.3% (n=113). A total of 88.5% of patients were admitted to non-ICU wards, with a mortality rate of 5.7%. Significant differences were observed in the distribution of hematological parameters between ICU-admitted and non-admitted patients. Neutrophil (OR: 23.96, 95% CI: 7.296-78.675) and white blood cell (WBC) count (OR: 36.677, 95% CI: 2.086-644.889) were the most significant predictors for ICU admission and survival, respectively. CONCLUSIONS: WBC and neutrophil counts exhibited high predictive value for ICU admission, while WBC, neutrophil, lymphocyte, and immature granulocyte (IG) counts were significant predictors of survival status among COVID-19 patients. These findings underscore the continued relevance of hematological markers in managing severe respiratory infections and improving critical care triage, with implications for current and future healthcare challenges.

Pre-clinical protective potentials of Carica papaya constituents in experimentally induced anemia.

OBJECTIVE: Anemia is a pathological condition characterized by reduced oxygen bioavailability and/or changes in hematological parameters. This study investigated the anti-anemic activities of Carica papaya (CP) phytoconstituents in aluminium-chloride-induced anemic rats. METHOD: Twenty-seven rats were randomized into nine groups of three rats as follows; group 1 was the normal (non-induced) group, 2-9 were anemic rats administered 1 mL distilled water, standard drug (3 mg/kg body weight (bw) ferrous sulphate), 100, 300 and 500 mg/kg bw of crude methanolic extract of CP (CMECP) of the leaf and 100, 300 and 500 mg/kg bw of CMECP of the seed respectively in the first stage of the study. In the second stage, thirty-three rats were randomized into eleven groups of three rats as follows; group 1 was the normal group, 2-11 were anemic rats treated with 1 mL distilled water, standard drug, 75 mg/kg bw, 150 mg/kg of alkaloid fraction of CP seed, 75 mg/kg bw, 150 mg/kg bw of flavonoid fraction of CP seed, 75 mg/kg bw and 150 mg/kg of alkaloid fraction of CP leaf, 75 mg/kg bw and 150 mg/kg bw of flavonoid fraction of CP leaf respectively. RESULTS: Treatment of anemic rats with CP extracts and fractions of the seed and leaf significantly reversed the hematological parameters and body weight of anemic rats in a dose independent fashion. The CMECP leaf at 100 and 500 mg/kg gave PCV of 42.50±0.50 and 47.00±0.50, while the seed gave 49.50±0.50 and 42.50±0.50 respectively after 2 weeks of treatment. However, the alkaloid and flavonoid fraction of CP presented better anti-anemic properties probably due to constituents' synergism. CONCLUSION: This study concluded that CP possesses phytoconstituents which potentiates it as a safe anti-anemic drug candidate.

Hematological abnormality and associated factors in newborns with hyperbilirubinemia before and after phototherapy at University of Gondar Comprehensive Specialized Hospital.

This study aimed to assess the magnitude of hematological toxicity and associated factors in newborns with hyperbilirubinemia. A cross-sectional study was conducted from April to December 2023. A total of 247 newborns were included. The data were collected using questionnaires and a data extraction sheet. Four 4 ml of blood was collected. A Sysmex KX-21 analyzer was used for blood analysis, and a Mindray BS-240 analyzer was used for bilirubin measurement. The data were entered into Epi-data and analyzed by SPSS. The logistic regression was used. The P value was set at 0.05. Before phototherapy, the hematological toxicities, such as anemia, leucopenia, and thrombocytopenia, were 45.7%, 22.2%, and 6.1%, respectively, whereas after phototherapy, anemia and thrombocytopenia, significantly increased, but the leucopenia, significantly decreased. The risk of developing anemia increased, 3.5, 2.7, and 2.1-fold among newborns with bilirubin > 18 mg/dl, with Rh blood group incompatibility, and treated with intensive phototherapy, respectively. Both low birth weight and intensive phototherapy increased the incidence of thrombocytopenia by 2 and 3.4-fold, respectively. Hematological toxicity was found to be a severe public health issue in newborns. Thus, strict follow-up and early detection of toxicity by considering aggravation factors are necessary.

Transient efficacy of buparvaquone against Theileria haneyi in chronically infected horses.

BACKGROUND: Theileria haneyi is one of the three known causative agents of equine piroplasmosis. While imidocarb is generally effective in the clearance of the highly pathogenic Theileria equi, it is ineffective in the treatment of T. haneyi. Moreover, co-infection with T. haneyi has been shown to impede the successful treatment of T. equi. Furthermore, tulathromycin and diclazuril have demonstrated inefficacy in eradicating T. haneyi. The absence of an effective therapeutic agent against this parasite represents a significant obstacle in managing equine piroplasmosis. METHODS: To address this issue, we evaluated the efficacy of buparvaquone in the treatment of T. haneyi in chronically infected horses. RESULTS: Our findings showed that treatment of horses with the recommended dose of 2.5 mg/kg of buparvaquone led to a rapid abatement of T. haneyi levels, to a level where the parasites were not detectable by nested PCR. Following treatment, the horses remained PCR negative for a minimum of seven weeks until recrudescence occurred. Subsequent re-administration of buparvaquone at an increased dosage of 6 mg/kg upon recrudescence failed to exert a theilericidal effect on T. haneyi. Throughout the treatment regimen, the hematological parameters of the horses and most components of the chemistry panel remained within the normal range, except for blood urea nitrogen levels, which fell below the normal range in certain instances. CONCLUSIONS: BPQ at 2.5 mg/kg and 6 mg/kg had a robust theilericidal effect but was ineffective in the clearance of the T. haneyi infection in persistently infected animals.

Efficacy and safety of topical tranexamic acid in spinal surgery: a systematic review and meta-analysis.

Purpose: This study aimed to assess the effects of topical tranexamic acid (tTXA) in spinal surgery to provide reliable clinical evidence for its usefulness. Methods: The PubMed, EMBASE, Medline, and Cochrane Central Register of Controlled Trials databases were comprehensively searched to identify randomized controlled trials and non-randomized controlled trials evaluating the effect of tTXA on blood loss during spine surgery. The observation indexes were intraoperative blood loss, total blood loss, output and duration of postoperative drainage, postoperative hematological variables, length of postoperative hospital stay, blood transfusion rate, and complication rate. Results: A total of 21 studies involving 1774 patients were included. Our results showed that the use of tTXA during spinal surgery significantly reduced the total blood loss, postoperative drainage volume, postoperative transfusion rate, duration of postoperative drainage, and postoperative hospital stay, and increased the serum hemoglobin concentration, thereby providing better clinical outcomes for surgical patients. However, tTXA had no effect on intraoperative blood loss and associated complications. Conclusion: On the basis of the available evidence, the present results provide strong clinical evidence of the clinical value of tTXA in spinal surgery and provide an important reference for future research and clinical decision-making.

Comparison of the accuracy of hematological parameters in the diagnosis of neonatal sepsis: a network meta-analysis.

BACKGROUND: Currently, there are hundreds of hematological parameters used for rapid diagnosis of neonatal sepsis, but there is no network meta-analysis to compare the diagnostic efficacy of these parameters. METHODS: We searched for literature on the diagnostic neonatal sepsis and selected 20 of the most common parameters to compare their diagnostic efficacy. We used Bayesian network meta-analysis, Frequentist network meta-analysis, and individual traditional diagnostic meta-analysis to analyze the data and verify the stability of the results. Based on the above analysis, we ranked the diagnostic efficacy of 20 parameters and searched for the optimal indicator. We also conducted subgroup analysis based on different designs. GRADE was used to evaluate the quality of evidence. RESULTS: 311 articles were included in the analysis, of which 206 articles were included in the network meta-analysis. Bayesian models fond the top three of the advantage index were P-SEP, SAA, and CD64. In Individual model, P-SEP, SAA, and CD64 had the best sensitivity; ABC, SAA, and P-SEP had the best specificity. Frequentist model showed that CD64, P-SEP, and IL-10 ranked in the top three for sensitivity, while P-SEP, ABC, and I/M in specificity. Overall, P-SEP, SAA, CD64, and PCT have good sensitivity and specificity among all the three methods. The results of subgroup analysis were consistent with the overall analysis. All evidence was mostly of moderate or low quality. CONCLUSIONS: P-SEP, SAA, CD64, and PCT have good diagnostic efficacy for neonatal sepsis. However, further studies are required to confirm these findings.

Dynamic Assessment of Hematological Parameters as Predictive Biomarkers for Disease Severity and Prognosis in COVID-19 Patients: A Longitudinal Study.

BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic, caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has led to substantial morbidity and mortality worldwide. Hematological abnormalities are common in COVID-19 patients and play a significant role in disease pathogenesis and prognosis. OBJECTIVE: This study aimed to longitudinally monitor hematological parameters in COVID-19 patients and investigate their predictive value for disease severity and prognosis. METHODS: A prospective longitudinal design was employed to enroll 121 adult patients diagnosed with COVID-19 based on positive SARS-CoV-2 reverse transcription-polymerase chain reaction (RT-PCR) test results. Baseline demographic and clinical data were collected, and hematological parameters, including complete blood count (CBC) indices, inflammatory markers, and coagulation profiles, were measured at predefined time points during hospitalization or outpatient visits. Follow-up assessments were conducted longitudinally to monitor the disease progression and clinical outcomes. RESULTS: This study revealed dynamic changes in hematological parameters over the course of COVID-19. Hemoglobin levels showed a decrease from baseline (mean ± SD: 12.5 ± 1.8 g/dL) to the peak of illness (10.2 ± 2.0 g/dL), indicating the development of anemia during the acute phase of infection. White blood cell counts demonstrated an initial increase (8.9 ± 3.2 × 10^9/L) followed by a decline (5.4 ± 1.9 × 10^9/L) as the disease progressed, suggesting an early inflammatory response followed by immune suppression. The platelet counts fluctuated, with a decrease observed during the acute phase (190 ± 50 × 10^9/L) and subsequent recovery during convalescence (240 ± 60 × 10^9/L). Inflammatory markers, such as C-reactive protein and interleukin-6, were elevated, peaking at 120 and 150 pg/mL, respectively, indicating systemic inflammation. Coagulation profiles showed abnormalities suggestive of COVID-19-associated coagulopathy, including elevated D-dimer levels (mean ± SD: 3.5 ± 1.2 µg/mL) and prolonged prothrombin time (15.8 ± 2.5 seconds). Longitudinal analysis of hematological parameters revealed associations between disease severity and clinical outcomes, with certain abnormalities correlating with an increased risk of complications and a poor prognosis. CONCLUSION: This study highlights the importance of monitoring hematological parameters in COVID-19 patients for risk stratification, prognostication, and guiding therapeutic interventions.

The effects of drone transportation on routine laboratory, immunohematology, flow cytometry and molecular analyses.

OBJECTIVES: Transportation of medical samples between laboratories or hospital sites is typically performed by motorized ground transport. Due to the increased traffic congestions in urban environments, drone transportation has become an attractive alternative for fast shipping of samples. In accordance with the CLSI guidelines and the ISO 15189 standard, the impact of this transportation type on sample integrity and performance of laboratory tests must be thoroughly validated. METHODS: Blood samples from 36 healthy volunteers and bacterial spiked urine samples were subjected to a 20-40 min drone flight before they were analyzed and compared with their counterparts that stayed on the ground. Effects on stability of 30 routine biochemical and hematological parameters, immunohematology tests and flow cytometry and molecular tests were evaluated. RESULTS: No clinically relevant effects on blood group typing, flow cytometry lymphocyte subset testing and on the stability of the multicopy opacity-associated proteins (Opa) genes in bacterial DNA nor on the number of Abelson murine leukemia viral oncogene homolog 1 (abl) housekeeping genes in human peripheral blood cells were seen. For three of the 30 biochemistry and hematology parameters a statistically significant difference was found: gamma-glutamyl transferase (gamma-GT), mean corpuscular hemoglobin (MCH) and thrombocyte count. A clinically relevant effect however was only seen for potassium and lactate dehydrogenase (LDH). CONCLUSIONS: Multi-rotor drone transportation can be used for medical sample transportation with no effect on the majority of the tested parameters, including flow cytometry and molecular analyses, with the exception of a limited clinical impact on potassium and LDH.

Acute Effects of Kickboxing K1 Matches on Hematological Parameters of Kickboxers.

While there is clear evidence in the literature that the hematological parameters in athletes of different sports are affected by exercise and varying loads, to our knowledge, there are limited studies on the real impact of kickboxing matches on kickboxers' hematological parameters. In this context, this cross-sectional study was conducted to examine the acute changes in the hematological parameters of kickboxers following K1 matches. With the participation of 10 kickboxing K1 athletes, the hematological parameters, including the WBC, Plt, Neut, Lymph, Mono, RBC, Hgb, Hct, CK, La, and glucose levels, were examined before and after matches. Paired sample t-tests were used to compare the pre-test and post-test hematological parameters of the participants. The findings indicated statistically significant differences in the post-match WBC, Plt, Neut, Lymph, CK, La, and glucose levels, while no statistically significant differences were observed in the RBC, Hct, Hgb, and CK levels (p < 0.05). These results not only emphasize the complexity of physiological changes in athletes, but also show consistency with various findings in the literature, while contradicting some. Therefore, it is highlighted that further research is needed to understand the effects of K1 matches on hematological parameters.

The First Thai Case of Nondeletional HbH Disease Caused by Compound Heterozygosity for α-Thalassemia-1 Chiang Rai (--CR) Type Deletion with Hb Constant Spring.

Hemoglobin (Hb) H disease presents a wide range of clinical phenotypes, from asymptomatic to severe forms, depending on significant genetic heterogeneity. This is the first report of clinical and hematological features of the nondeletional HbH disease caused by --CR/αCSα. A baby was born to a father and a mother with --CR and αCSα carriers, respectively. She had severe symptomatic hypochromic microcytic anemia at 2 months of age with Hb 7.8 g/dL, packed cell volume (PCV) 0.27 L/L, mean corpuscular volume (MCV) 64.3 fL, and mean corpuscular Hb (MCH) 18.3 pg. The Hb analysis using capillary electrophoresis (CE) showed Hb Bart's, HbH, and Hb CS peaks at 17.1%, 2.2%, and 1.6%, respectively. A better understanding of a patient's clinical and hematological features with --CR/αCSα is useful for hemoglobinopathy counseling for the national thalassemia controlling program.

Hemodialysis in End-Stage Renal Disease Patients Is Associated with Altered Platelet, MCV, MPV, and INR Levels: A Pilot Study.

OBJECTIVE: Both chronic kidney disease and its main treatment, hemodialysis (HD), are associated with hematological abnormalities. However, little is known about how starting hemodialysis when already in end-stage renal disease (ESRD) affects hematological parameters. This study investigated the effect of HD on hematological and coagulation markers among ESRD patients. METHODS: A retrospective study was carried out on 43 HD-ESRD patients from January to December 2022. The data were collected from Sabt Alalaya General Hospital in Belgarn, Saudi Arabia. Using GraphPad Prism, multiple unpaired t-tests were utilized to compare hematological and coagulation markers between the patients and healthy subjects. RESULTS: The 43 HD-ESRD patients (46.5% male and 53.5% female) ranged in age from 20 to 89 years. The data obtained from our analysis unsurprisingly revealed significant variation in hematological parameters and coagulation patterns among HD-ESRD patients. Most notably, there were gradual and significant changes in platelet, MCV, MPV, and INR values during the assessment time. CONCLUSION: This investigation verified the possible occurrence of macrocytosis and thrombotic conditions among patients with ESRD who undergo HD. It is recommended to closely observe patients undergoing this procedure, with a specific focus on platelet, MCV, MPV, and INR levels as potential indications.

Pharmacological composition based on bacteriocinnisin in experiments in vitro and in vivo.

Background: Antibiotic resistance is a global health problem related to the transmission of bacteria and genes between humans and animals. The development of new drugs with antimicrobial activity research is an urgent task of modern science. Aim: The article presents data of in vitro and in vivo experiments on new pharmaceutical composition based on nisin. Methods: The antimicrobial activity was studied on the mastitis pathogens. To identify microorganisms the Matrix-Assisted Lazer Desorption/Ionization Time-of-Flight (MALDI-TOF) (mass spectrometry) method was performed using. To determine sensitivity, the serial dilution method and the diffusion method were used. On laboratory animals, biochemical, hematological, and histological research methods were used. Female nonlinear white laboratory rats were used, which were divided into one control group and three experimental ones. Results: "Duration" factor was statistically significant for the following indicators: hemoglobin, hematocrit, leukocytes, lymphocytes, erythrocyte sedimentation rate, and eosinophils. The "Dose" factor did not show significance for any indicator, which means that the effect was similar regardless of the dose chosen. When analyzing the biochemical indicators, significant differences were found in the "Duration" and "Dose" factors, in the direction of a decrease in the indicators of total protein, globulins, urea, and an increase in the concentration of alkaline phosphatase. When conducting histological studies in the first experimental group, it was established that there were no changes in the structural and functional units of the organs. In animals of the second experimental group, the presence of reversible pathological processes of a compensatory nature was noted. More profound changes in the structure of the studied organs were recorded in the third experimental group. Conclusion: An in vitro study on cell cultures showed that the pharmacological composition has high antimicrobial activity against isolates from the mammary gland secretion of cows with mastitis. An in vivo study on laboratory animals showed that the developed composition belongs to the IV class of substances "low-hazard substances". Histological examination made it possible to select the safest dose of the pharmacological composition of no more than 500 mg/kg.

Age, gender, and infectious status-wise assessments of hematological parameters among patients with dengue infection.

Background: The aim of this study was to examine the impact of different stages of dengue infection on immune cell counts among dengue patients and to compare them with cases of non-dengue febrile illness. Methods: The recruited patients were divided into two groups: the first group served as a control (n = 55), representing non-dengue febrile illness, and the second group was identified as dengue febrile illness (n = 149), which was further divided into three groups based on infection stage. Blood samples were collected from the selected patients and subjected to blood cell component analysis. To find IgG and IgM as well as the dengue virus non-structural antigen-1 (NS1), an immunochromatographic test (ICT) kit was utilized. Additionally, a hematological analyzer was used to determine complete blood cell counts (CBC). Data was thoroughly analyzed using Graph Pad Prism 6 software. The differences in means of different groups were calculated by applying the student's t-test. Results: The findings revealed the presence of severe leucopenia and thrombocytopenia at stages 1 and 2, accompanied by lymphopenia at stage 1. Group comparisons indicated that only teenagers exhibited a significantly lower white blood cell count compared to older individuals, while no significant differences were observed in lymphocytes, platelets, and monocytes across all age groups. Comparing different age groups of normal individuals to dengue-infected patients, the results unveiled that leucopenia was most severe in adults, followed by teenagers and children, with no significant difference in the elderly. Furthermore, adults showed the greatest degree of thrombocytopenia, followed by teens and kids, with the elderly showing the greatest degree of thrombocytopenia. Adults and teens showed extreme neutrophilia, whereas young children and the elderly showed no discernible abnormalities. Elderly patients experienced a marked decrease in monocyte count, a phenomenon not observed in other age groups. Conclusion: In conclusion both, leucopenia & thrombocytopenia, are most severe in stages 1 and 2, whereas neutrophilia & lymphopenia are predominantly severe in stage 1. These results imply that the consequences associated with dengue infection are more severe in the early stages and tend to ameliorate as the patient progresses toward recovery.

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

INTRODUCTION: 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. METHODS: 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. RESULTS: Total WBC, neutrophil, lymphocyte, platelet, RBC counting, Hb, HCT, MCV, MCH, and hsCRP levels were significantly changed with different disease severity (p<0.0001). Also, there were significant differences between different time intervals for WBC and RBC parameters (p<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<0.0001). CONCLUSION: 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.
