Gastrointestinal Bleeding and Survival After a Nadir Hemoglobin

We report 2 cases of gastrointestinal bleeding and profound anemia in Jehovah's Witness patients (with nadir hemoglobin of 2.1 and 2.8 g/dL), both of whom survived until discharge to home. Management included supportive care, antifibrinolytics, and an aggressive erythropoietic regimen. Despite previous reports of high mortality with hemoglobin concentrations less than 5 to 6 g/dL, these patients illustrate that meticulous care in selected patients with severe anemia can lead to successful outcomes, without transfusion.

Regulatory role of ETS1 transcription factor in hemocytes proliferation in Anadara granosa

The ETS1 transcription factor is crucial in the process of biological development. In vertebrate, ETS1 plays a pivotal role in promoting endothelial cell proliferation and angiogenesis. However, the identity and function of ETS1 remains unclear in mollusks. In this study, an ETS1 homolog (named as AgETS1) was identified in blood clam Anadara granosa (synonym: Tegillarca granosa). The full length of the AgETS1 transcription factor is 1569 bp, consisting of 539 amino acids, including the Sterile Alpha Motif (SAM) domain, which can recognize and bind to sequence of GGAA. Tissue expression analysis of A. granosa showed that AgETS1 exhibits the highest expression level in the gill tissues (51.5-fold of that in hemocyte, p < 0.05). AgETS1 mRNA transcripts were predominantly expressed during larval development, from zygote to trochophore stage. Moreover, the expression levels of AgETS1 in blood clams with high hemoglobin concentration (hemocyte count >1.75 × 108 cells/mL) were significantly higher than that in blood clams with low hemoglobin concentration (hemocyte count <8.5 × 107 cells/mL) (p < 0.05). RNA interfering (RNAi) of AgETS1 induced a corresponding decrease in the number of hemocytes in the hemolymph and a reduction in EdU-marked proliferating cells in the gill tissue. These results indicated that the ETS1 actively regulated the proliferation of hemocytes in A. granosa.

Evaluating the effectiveness of immediate vs. elective thoracic endovascular aortic repair for blunt thoracic aortic injury

PurposeTo evaluate the relationship between the timing of thoracic endovascular aortic repair (TEVAR) for blunt thoracic aortic injury (BTAI) and prognosis. MethodsThis is a single-center retrospective cohort study. Patients who received TEVAR for BTAI at our institution from October 2016 to September 2023 were divided into 2 categories depending on the injury severity score (ISS) (≤ 25 vs. > 25) and when the TEVAR was performed for BTAI (within 24 h vs. after 24 h), respectively. The analysis included all patients who received TEVAR treatment after being diagnosed with BTAI through whole-body CT angiography. Patients treated with open repair and non-operative management were excluded. After propensity-score matching for various factors, outcomes during hospitalization and follow-up were compared. These factors included demographics, comorbidities, concomitant injuries, cause and location of aortic injury, Glasgow coma scale score, society for vascular surgery grading, hemoglobin concentration, creatinine concentration, shock, systolic blood pressure, and heart rate at admission. The comparison was conducted using SPSS 26 software. Continuous variables were presented as either the mean ± standard deviation or median (Q1, Q3), and were compared using either the t-test or the Mann-Whitney U test. Categorical variables were expressed as n (%), and comparisons were made between the 2 groups using the χ2 test or Fisher’s exact test. Statistical significance was defined as a 2-sided p < 0.05. ResultsIn total, 110 patients were involved in the study, with 65 (59.1%) patients having ISS scores > 25 and 32 (29.1%) receiving immediate TEVAR. The perioperative overall mortality rate in the group with ISS > 25 was significantly higher than that in the group with ISS ≤ 25 (11 (16.9%) vs. 2 (4.4%), p < 0.001). Upon admission, the elective group exhibited a notably higher Glasgow coma scale score (median (Q1, Q3)) compared to the immediate group (15 (12, 15) vs. 13.5 (9, 15), p = 0.039), while the creatinine concentration (median (Q1, Q3)) at admission was significantly higher in the immediate group (90.5 (63.8, 144.0) vs. 71.5 (58.3, 80.8), p = 0.012). The final sample included 52 matched patients. Complications occurred significantly less frequently in the elective group compared to the immediate group (16 (50.0%) vs. 3 (10.0%), p < 0.001). Single-factor analysis of variance showed that complications in hospitalized patients were significantly associated with immediate TEVAR as the sole independent risk factor (odds ratio: 9.000, 95% confidence interval: 2.266 – 35.752, p = 0.002). ConclusionIn this propensity-score matched analysis of patients undergoing TEVAR for BTAI, elective TEVAR was significantly associated with a lower risk of complication rates. In this study using propensity-score matching, patients who underwent elective TEVAR for BTAI had lower complication rates than immediate TEVAR.

Textile dyeing wastewater negatively influences the hematological profile and reproductive health of male Swiss albino mice

Objective: To determine the effects of textile dyeing industrial wastewater on the hematological parameters and reproductive health including histoarchitecture of male gonad (testes) of mice. Methods: Twenty-four Swiss albino mice at 4-weeks old were divided into four groups (n=6 per group). Mice of group 1 supplied with normal drinking water were served as the control group. Mice of group 2, 3 and 4 were supplied normal drinking water mixed with textile dyeing wastewater at 5%, 10% and 20% concentration, respectively. After completing 24 weeks of treatment, different hematological profile, weight of testes, gonadosomatic index (GSI), sperm concentration and morphology were measured. Moreover, histopathological changes in testes were examined. Results: Hematocrit value and hemoglobin concentrations were decreased in all groups of wastewater-treated mice compared to the control group. Likewise, weight of testes, GSI and sperm concentration were decreased significantly in wastewater-treated mice in comparison to the control group. The percentage of morphologically healthy epididymal sperm was significantly reduced in wastewater-treated mice. Histopathological examination revealed degenerative changes in seminiferous tubules, a smaller number of spermatogenic cells, elongation of seminiferous tubules and degenerative changes of seminiferous tubules in wastewater- treated mice. Conclusions: Textile dyeing wastewater has harmful effects on hematological profile and reproductive health of male mice.

Paravertebral block with lignocaine-bupivacaine mixture in goats

Loco-regional anaesthesia and sedation protocols are becoming more popular in ruminant. This research compared some effects of xylazine or acepromazine in combination with lignocaine-bupivacaine mixture for paravertebral nerve block in goats. Twenty adult, apparently healthy West African Dwarf goats were randomly allocated to two groups (five males and five females each). Each group received either xylazine (0.05 mg/kg) + 2 % lignocaine (2mg/kg) – 0.5 % bupivacaine (0.95 mg/kg) mixture (XLB) or acepromazine (0.05 mg/kg) + lignocaine-bupivacaine mixture (ALB). Clinical parameters were recorded immediately (0 minutes) and at 10-minute intervals for an hour and 24 hours. Venipuncture was carried out via jugular vein for haematology before administration of drug (B0), 30 minutes (B30), 60 minutes (B60) and 24 hours (B24). Data was analyzed using descriptive statistics and presented as mean and standard deviation at a significance level of 0.05. The onset of deep sedation following administration of acepromazine was 31.5 ± 0.97, while it was 2.90 ± 0.57 for xylazine. Acepromazine significantly (P &lt; 0.05) reduced the rectal temperatures (RT) of the goats within the first 20 minutes and significantly reduced the respiratory rates of the goats when compared to xylazine. None of the drugs significantly altered the heart rate of the goats. None of the changes in haematological parameters was statistically significant across the sampling time frame. However, red cell parameters (Packed cell volume, red blood cell count, and haemoglobin concentration) and Lymphocyte count were significantly depressed after XLB administration. All the haematological changes were restored to pre-anaesthetic values after 24hours. This study demonstrates that xylazine can be a beneficial alternative and desirable for emergencies in minor ruminant sedation.

Assessment of the Effect of Meaningful Occupations on Motivation by Orbitofrontal Cortex Activation Using Near-Infrared Spectroscopy.

Meaningful occupations are those perceived as important by an individual. Research on meaningful occupations relies on subjective data and requires qualitative inquiries. Therefore, assessing the meaning of occupations using objective methods is challenging. As orbitofrontal cortex (OFC) activation is part of the reward system network involved in motivation, it could aid in assessing the meaning of occupations. We aimed to investigate the effect of meaningful occupations on motivation by measuring OFC activation using near-infrared spectroscopy (NIRS). Eight young and healthy participants were enrolled in this study. The occupation was set as "cooking," and its importance was confirmed using the Canadian Occupational Performance Measure (COPM). NIRS was performed using an OEG-16 (Spectareteh Inc.). The target task involved watching a cooking video, while the control task consisted of looking at a "+" sign on a blank sheet of paper. OFC activation was measured based on changes in oxygenated hemoglobin (oxy-Hb) concentration using a block design. Participants with COPM scores of eight or more were classified into the "meaningful occupation performance" group, while those with scores of seven or lower were classified into the "meaningful occupation non-performance" group. Changes in oxy-Hb concentrations between the two groups were compared using the Mann-Whitney U test. Four participants were assigned to the meaningful occupation group (frequency of implementation: various times per week for all participants), and four participants were assigned to the meaningful occupation non-performance group (frequency of implementation: various times per week for one participant, various times per month for one participant, and various times per year for two participants). Statistical analysis revealed significant differences in the changes in the oxy-Hb concentration in the left and bilateral OFC. This study suggests that it is important to focus on meaningful occupations that individuals consider important in order to activate the reward system and increase motivation.

Beyond symptomatology: A comparative analysis of unilateral and bilateral macronodular mild autonomous cortisol secretion.

To investigate the clinical, laboratory findingsand signal intensity index (SII) on magnetic resonance imaging (MRI) of patients with bilateral and unilateral macronodular mild autonomous cortisol secretion (MACS). Clinical and laboratory findings of 81patients with MACS were examined from retrospective records. SII of adenomas and internodular areas were evaluated by MRI. The unilateral group included patients with an adrenal macronodule (≥1 cm) in a single adrenal gland, while the bilateral group included patients with at least one macronodule in both adrenal glands. In total, 46 patients were in the unilateral (57%), while 35 (43%) patients were in the bilateral groups. The dehydroepiandrosterone sulphate(DHEA-S) level was lower in the unilateral than in the bilateral group (p < .001). The presence of type 2 diabetes mellitus (T2DM), glycosylated haemoglobin (HbA1c) and low-density lipoprotein(LDL) concentrations were higher in the bilateral group (p < .05). However, no significant difference was detected in terms of adrenocorticotropic hormone(ACTH) and overnight 1 mgdexamethasone suppression test (DST) between the two groups (p > .05). There was no difference in SII between adenomas within the same patient, as well as between the unilateral and bilateral groups (p > .05). Logistic regression analysis based on the differentiation between unilateral and bilateral macronodular MACS demonstrated that DHEA-S, HbA1cand LDL concentrations were associated factors. DHEA-S levels may not be as suppressed in patients with bilateral macronodular MACS as compared to those with unilateral adenoma. T2DM and hypercholesterolaemia have a higher frequency in bilateral patients. However, ACTH, overnight 1 mgDSTand SII may not provide additional information for differentiation of bilaterality and unilaterality.

Serum calcium level at 32 weeks of gestation could be applied as a predictor of preterm delivery: a retrospective study

Preterm delivery (PTD) is associated with severe adverse maternal and neonatal outcomes and higher medical costs. Therefore, PTD warrants more attention. However, predicting PTD remains a challenge for researchers. This study aimed to investigate potential prenatal predictors of PTD. We retrospectively recruited pregnant women who experienced either PTD or term delivery (TD) and underwent laboratory examinations at 32 weeks of gestation. We compared the test results between the two groups and performed logistic regression analysis and receiver operating characteristic (ROC) curve analysis to identify risk factors and predictive factors for PTD. Our investigation revealed that the PTD cohort exhibited statistically significant elevations in lymphocyte count, mean corpuscular hemoglobin concentration, calcium, uric acid, alkaline phosphatase, triglycerides, and total bile acids. Conversely, the PTD group demonstrated statistically significant reductions in mean corpuscular volume, homocysteine, neutrophil to lymphocyte ratio (NLR), monocyte to lymphocyte ratio (MLR), neutrophils to (white blood cells–neutrophils) ratio (dNLR), and (neutrophils × monocytes) to lymphocyte ratio (SIRI). The ROC curve analysis revealed that calcium had an area under the curve (AUC) of 0.705, with a cut-off value of 2.215. Logistic regression analysis showed that premature rupture of membranes was an independent risk factor for PTD. Our study demonstrated that serum calcium levels, NLR, dNLR, and other laboratory tests conducted at 32 weeks of gestation can serve as predictors for PTD. Furthermore, we identified premature rupture of membranes as a risk factor for PTD.

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

This study aimed to assess the effects of topical tranexamic acid (tTXA) in spinal surgery to provide reliable clinical evidence for its usefulness. 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. 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. 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.

Non-invasive hemoglobin measurement using optical method

The measurement of Hemoglobin (Hb) by the non-invasive method is gaining popularity. The system, consisting of a photodiode is placed in between a Red (630 nm) and an IR (940 nm) LED, along with the signal conditioning circuits. 10 healthy male (8) and female (2) volunteers in the age group between 21 and 24 were recruited for this study. During measurement, the fingertip of a volunteer was placed on the measurement pad. Visible and IR lights are switched ON one after the other. The optical absorbance of the blood component in the arteries was detected by the photodiode using the reflectance method. The current generated was converted into voltage and was processed to remove the noise associated with the signal. From this, the concentration of Hb of the volunteers was determined. On the same day they were taken to the clinical laboratory and Hb values were obtained by the standard invasive method. Hemoglobin values obtained from the two methods were compared and an accuracy of 96.31 % and correlation coefficient value of 0.932405 was achieved. From the Bland -Altman plot, the results obtained are within the confidence interval of 95 %. The error of 3 % can be reduced further by employing sophisticated signal conditioning techniques. The proposed non-invasive method took only a few seconds to find the hemoglobin concentration than the invasive lab test. This method can accelerate the decision-making process in emergency situations.

Comparison of sensitivity between blood parameters and a genotoxic biomarker at low blood Pb levels: A population-based study

BackgroundPrevious studies reported that lead (Pb) exposure induced adverse health effects at high exposure concentrations, however, there have been limited data on sensitivity comparisons among different health outcomes at low blood Pb levels. ObjectivesTo compare sensitivity between blood parameters and a genotoxic biomarker among workers exposed to low blood Pb levels (< 20 µg/dl), and to estimate a benchmark dose (BMD). MethodsPb-exposed workers were recruited from a lead-acid storage battery plant. Their blood lead levels (BLLs) were measured. Blood parameters and micronuclei (MN) frequencies were determined. Multivariate linear or Poisson regression was used to analyze relationships between blood parameters or MN frequencies with BLLs. Two BMD software were used to calculate BMD and its 95 % lower confidence limit (BMDL) for BLLs. ResultsThe median BLL for 611 workers was 10.44 µg/dl with the 25th and 75th percentile being 7.37 and 14.62 µg/dl among all participants. There were significantly negative correlations between blood parameters and BLLs. However, MN frequencies correlated positively with BLLs (all P<0.05). Results from the two BMD software revealed that the dichotomous model was superior to the continuous model, and the BMDL for BLL derived from red blood cell (RBC) was 15.11 µg/dl, from hemoglobin (HGB) was 8.50 µg/dl, from mean corpuscular hemoglobin (MCH) was 7.87 µg/dl, from mean corpuscular hemoglobin concentration (MCHC) was 3.98 µg/dl, from mean corpuscular volume (MCV) was 11.44 µg/dl, and from hematocrit (HCT) was 6.65 µg/dl. The conservative BMDL obtained from the MN data was 7.52 µg/dl. ConclusionOur study shows that low dose Pb exposure caused decrease of blood parameters and increase of MN frequencies. The genotoxic biomarker was more sensitive than most blood parameters. BMDLs for BLL derived from MN frequencies and the red blood cell indicators should be considered as new occupational exposure limits. Our results suggest that MN assay can be considered as a part of occupational health examination items.

Biochemical Markers in the Prediction of Pregnancy Outcome in Gestational Diabetes Mellitus.

Background and Objectives: Gestational diabetes mellitus (GDM) may impact both maternal and fetal/neonatal health. The identification of prognostic indicators for GDM may improve risk assessment and selection of patient for intensive monitoring. The aim of this study was to find potential predictors of adverse pregnancy outcome in GDM and normoglycemic patients by comparing the levels of different biochemical parameters and the values of blood cell count (BCC) between GDM and normoglycemic patients and between patients with adverse and good outcome. Materials and Methods: Prospective clinical study included 49 patients with GDM (study group) and 44 healthy pregnant women (control group) who underwent oral glucose tolerance test (OGTT) at gestational age of 24-28 weeks. At the time of OGTT peripheral blood was taken for the determination of glucose levels, insulin, glycated hemoglobin, lipid status, homeostatic model assessment, BCC, iron and zinc metabolism, liver function, kidney function and inflammatory status. Each group was divided into two subgroups-normal and poor pregnancy outcome. Results: Higher RBC, hemoglobin concentration, hematocrit value, fasting glucose, uric acid and fibrinogen were found in GDM patients compared to control group. In GDM patients with poor pregnancy outcome values of fibrinogen, ALT, sedimentation rate, granulocyte and total leukocyte counts were elevated, while the serum level of zinc was significantly lower. Higher level of fibrinogen was found in normoglycemic patients with adverse pregnancy outcomes. ROC curve was constructed in order to assess fibrinogen's biomarker potential. The established AUC value for diagnostic ROC was 0.816 (p < 0.001, 95% CI 0.691-0.941), while the AUC value for assessing fibrinogen's potential to predict poor pregnancy outcome in GDM was 0.751 (p = 0.0096, 95% CI 0.561-0.941). Conclusions: The results of our study demonstrated that the best prognostic potential in GDM showed inflammation related parameters, identifying fibrinogen as a parameter with both diagnostic and prognostic ability.

Cerebral homeostasis and orthostatic responses in residents of the highest city in the world

Permanent residence at high-altitude and chronic mountain sickness (CMS) may alter the cerebrovascular homeostasis and orthostatic responses. Healthy male participants living at sea-level (LL; n = 15), 3800 m (HL3800m; n = 13) and 5100 m (HL5100m; n = 17), respectively, and CMS highlanders living at 5100 m (n = 31) were recruited. Middle cerebral artery mean blood flow velocity (MCAv), cerebral oxygen delivery (CDO2), mean blood pressure (MAP), heart rate variability and spontaneuous cardiac baroreflex sensitivity (cBRS) were assessed while sitting, initial 30 s and after 3 min of standing. Cerebral autoregulation index (ARI) was estimated (ΔMCAv%baseline)/ΔMAP%baseline) in response to the orthostatic challenge. Altitude and CMS were associated with hypoxemia and elevated hemoglobin concentration. While sitting, MCAv and LFpower negatively correlated with altitude but were not affected by CMS. CDO2 remained preserved. BRS was comparable across all altitudes, but lower with CMS. Within initial 30 s of standing, altitude and CMS correlated with a lesser ΔMAP while ARI remained unaffected. After 3 min standing, MCAv, CDO2 and cBRS remained preserved across altitudes. The LF/HF ratio increased in HL5100m compared to LL and HL3800m from sitting to standing. In contrary, CMS showed blunted autonomic nervous activation in responses to standing. Despite altitude- and CMS-associated hypoxemia, erythrocytosis and impaired blood pressure regulation (CMS only), cerebral homeostasis remained overall preserved.

Highly Sensitive Plasmon Refractive Index Sensor Based on MIM Waveguide.

This paper introduces a novel plasmon refractive index nanosensor structure based on Fano resonance. The structure comprises a metal-insulator-metal (MIM) waveguide with an inverted rectangular cavity and a circle minus a small internal circle plus a rectangular cavity (CMSICPRC). This study employs the finite element method (FEM) to analyze the sensing characteristics of the structure. The results demonstrate that the geometrical parameters of specific structures exert a considerable influence on the sensing characteristics. Simulated experimental data show that the maximum sensitivity of this structure is 3240 nm/RIU, with a figure of merit (FOM) of 52.25. Additionally, the sensor can be used in biology, for example, to detect the concentration of hemoglobin in blood. The sensitivity of the sensor in this application, according to our calculations, can be 0.82 nm∙g/L.

Anaemia among school-going adolescents in Burkina Faso: Prevalence and associated factors.

Adolescence, a stage of growth between 10 and 19 years, is a transitional period of intense cognitive, emotionaland physical development. Though iron deficiency is theleading cause of morbidity and mortality among this age group, nutritional interventions targeting adolescents are rare. To inform policy and practice aimed at adolescent health, we established the burden of anaemia among school-going adolescents in Center West Burkina Faso and investigated the potential explanatory factors. A cross-sectional survey was conducted between January and March 2021. Blood samples, socio-demographic, socioeconomic, anthropometric, dietaryand water, sanitation and hygiene data from 2947 students aged 10-18 years were collected. Anaemia was determined by the World Health Organization's sex- and age-specific haemoglobin concentrations. χ2 tests and logistic regressions were used to identify factors associated with anaemia. The prevalence of anaemia among adolescents in the sample was 36.2%, including 24.2% mild, 11.6% moderateand 0.4% severe anaemia. Compared to males, females were 19% less likely to have mild anaemia (adjusted Odds Ratio [aOR] = 0.81; 95% confidence intervals [CI]: 0.689, 0.955) but 42% more likely to be moderately or severely anaemic (aOR = 1.42; 95% CI: 1.102, 1.831). Among iron-rich foods, tamarind (aOR = 0.75; 95% CI: 0.610, 0.929) and pumpkin leaves (aOR = 0.77; 95% CI: 0.605, 0.974) were associated with lower odds of anaemia. Several water, sanitation and hygiene factors were associated with higher haemoglobin, including handwashing after toilet use (β = 0.50; 95% CI: 0.031, 0.966)andtooth brushing twice daily (β = 0.19; 95% CI: 0.030, 0.354). Anaemia among adolescents in Burkina Faso should be addressed with interventions targeting diet, sanitationand hygiene.

Reliability of brain metrics derived from a Time-Domain Functional Near-Infrared Spectroscopy System

With the growing interest in establishing brain-based biomarkers for precision medicine, there is a need for noninvasive, scalable neuroimaging devices that yield valid and reliable metrics. Kernel’s second-generation Flow2 Time-Domain Functional Near-Infrared Spectroscopy (TD-fNIRS) system meets the requirements of noninvasive and scalable neuroimaging, and uses a validated modality to measure brain function. In this work, we investigate the test-retest reliability (TRR) of a set of metrics derived from the Flow2 recordings. We adopted a repeated-measures design with 49 healthy participants, and quantified TRR over multiple time points and different headsets—in different experimental conditions including a resting state, a sensory, and a cognitive task. Results demonstrated high reliability in resting state features including hemoglobin concentrations, head tissue light attenuation, amplitude of low frequency fluctuations, and functional connectivity. Additionally, passive auditory and Go/No-Go inhibitory control tasks each exhibited similar activation patterns across days. Notably, areas with the highest reliability were in auditory regions during the auditory task, and right prefrontal regions during the Go/No-Go task, consistent with prior literature. This study underscores the reliability of Flow2-derived metrics, supporting its potential to actualize the vision of using brain-based biomarkers for diagnosis, treatment selection and treatment monitoring of neuropsychiatric and neurocognitive disorders.

BIOCHEMICAL AND HISTOLOGICAL STUDIES ON ADVERSE EFFECTS OF DIETARY WEIGHT LOSS SUPPLEMENT ON FEMALE RATS: ADIOS

Herbal and dietary supplements are commonly used throughout the world; these unlicensed supplements are not recommended due to concerns about their clinical efficacy and safety. Adios are marketed for weight loss in Iraq and many other countries and are commonly used by women. The safety of these weight loss aids is unknown. This study aimed to evaluate adios adverse effects by conducting biochemical, hematological, and histological examinations on the liver and kidney. Rats were orally administrated for 30 days with different concentrations of adios supplements (0.001g/100g), (0.002g/100g), and (0.003g/100g) as low (LD) medium (MD) and high (HD) concentrations, respectively. The results showed no weight loss in rats over 30 days across experiments in all the treated groups (LD, MD, and HD) compared to the control. Adios showed significant differences between the control and the treated concentrations in the following hematological parameters: white blood cells (WBC), mean corpuscular volume (MCV), mean corpuscular hemoglobin concentration (MCHC), lymphocyte (LYM), and red cell distribution width (RDW) in a dose-dependent pattern. Furthermore, there were various alteration in the histopathological examination of the kidney and liver. From the current data, it can be concluded that adios has zero efficacy in weight loss and is not recommended for use because it has adverse effects on many hematological and biochemical parameters and with obvious pathological changes in both the kidney and liver.

A Review on the Pharmacokinetics and Toxicological Profile of Rabeprazole

Rabeprazole, a proton pump inhibitor, is used for individuals with ulcers. The prodrug is transformed into an active sulphenamide form by the acidic conditions present in the parietal cells. Rabeprazole inhibits the H+K+ ATPase of the gastric cells, leading to a decrease in the generation of stomach acid in both normal and stimulated situations. The present review was based on the pharmacokinetics and toxicological profile of Rabeprazole. Once absorbed into the body, approximately 96.3–97% of rabeprazole is bound to plasma proteins. In humans, the half-life of rabeprazole is approximately one hour. The peak concentration of rabeprazole in human plasma following a single oral dose does not appear until around 3.5 hours later. Rabeprazole is metabolised mostly by the liver. Once the liver has metabolised the medicine, 90% of it will be excreted via the kidneys. The elimination fraction is 10%. Rabeprazole is mostly metabolised by the cytochrome P450 enzymes CYP2C19 and CYP3A4. . It concluded that in the human pylorus, it decreased muscular tone, maximal contraction values, and contraction frequencies. When diclofenac sodium SR, glucosamine, diacerein, calcium, and vitamin D preparations were administered in addition to rabeprazole, the patients experienced GI bleeding, fatty liver grade 1, mild epigastric discomfort, black stools, and decreased haemoglobin content.

Hematological indices: potential markers of disease activity in ankylosing spondylitis patients treated with biological drugs

BackgroundSome important hematological indices implement acute phase reactions. They can be used to assess disease activity and therapeutic response in many inflammatory conditions. This work aimed to determine whether different hematological indices can be used to assess disease activity and therapeutic response in patients with ankylosing spondylitis (AS) on biological drugs.Patients and methodsNinety-seven AS patients and a similar number of controls were involved in the current study. The Ankylosing Spondylitis Disease Activity Score (ASDAS) was used to assess the disease activity. Different complete blood count parameters and indices were assessed.ResultsThere was a significant difference between the patients and controls as regards mean corpuscular volume, mean corpuscular hemoglobin, red blood cells count, red cell distribution width, mean platelet volume, platelet-to-lymphocyte ratio (PLR), and systemic immune-inflammation index (SII). Moreover, there was a statistical correlation between ASDAS on one side and hemoglobin (Hb), hematocrit (HTC), lymphocyte count, neutrophil-to-lymphocyte ratio (NLR), PLR, and SII on the other side. When the patient group was divided into 2 subgroups according to ASDAS, with patients with inactive and low disease activity in one subgroup and those with very high and high disease activity in another subgroup, there was a significant difference as regards Hb, HTC, mean corpuscular hemoglobin concentration, NLR, PLR, SII, and also ESR and CRP levels. Moreover, there was a significant correlation between PLR and SII levels on one side and ESR on the other side.ConclusionHematological indices such as PLR, NLR, and SII might be potential markers for follow-up of disease activity and therapeutic response in AS patients treated with biological therapy. This emphasizes the significance of a comprehensive approach for AS patient assessment and follow-up of therapeutic drugs, considering inflammatory markers, hematological indices, and disease activity scores.

Effect of probiotics on hematology and histopathology of organs associated with immune system in male and female Wistar rats

In the present study, potential probiotics were isolated from dairy products and characterized on a molecular basis. Male and female (16 + 16, n = 4) Wistar rats were randomly assigned to 5 groups to revise the effects of isolated potential probiotics on the gut immune system: 0-day, negative control, positive control (commercial product Lactobacillus acidophilus-14), laboratory isolated strains Pro-3 (Weissella confusa MZ735961), and Pro-4 (Lactiplantibacillus plantarum MZ727611). Aspartate-aminotransferase, Interleukin-6, bilirubin, and Alanine-transaminase values in both genders were expected but AST and creatinine values had a minor increase in the female group compared to the male probiotic-treated group. Cellular blood count level of mean corpuscular hemoglobin in male groups showed no considerable differences (p = 0.95), while there were decreased differences (p = 0.00) in female groups. The level of mean corpuscular hemoglobin concentration (MCHC) showed distinct variations (p = 0.02) in male groups, while these values were insignificant changes (p > 0.05) among female groups. No damage to the liver, thymus, or colon was ascertained based on morphological findings. The colon wall thickness, external muscle, crypt depth, and mucosa were significantly (p = 0.03) improved in rats given potential probiotics. In conclusion, probiotic supplementation stimulates the immune system. It may protect the intestinal mucosa by strengthening the gut’s immune system and promoting intestinal efficiency (nutrient absorption and number of goblet cells). L. plantarum can therefore offer a reliable, affordable, and safe treatment for functional gastrointestinal illnesses.
