Analysis of Random Lasing in Human Blood.

Random lasing (RL) is an optical phenomenon that arises from the combination of light amplification with optical feedback through multiple scattering events. In this paper, we present our investigations of RL generation from human blood samples. We tested mixtures of rhodamine B dye solutions with different blood components, including platelets, lymphocytes, erythrocytes, and whole blood. Intense coherent RL was obtained in all cases at relatively low pump thresholds, except for erythrocytes. We also studied the potential of RL signal analysis for biosensing applications using blood samples from healthy individuals and patients suffering from Chronic Lymphocytic Leukemia (CLL). CLL is a blood disease characterized by a high count of lymphocytes with significant morphological changes. A statistical analysis of the RL spectra based on principal component and linear discriminant analyses was conducted for classification purposes. RL-based sample discrimination was conducted for whole blood, platelet, and lymphocyte samples, being especially successful (86.7%) for the latter. Our results highlight the potential of RL analysis as a sensing tool in blood.

Importance of self-management interventions in hypertension patients: a scoping review

Hypertension is a prevalent chronic condition that requires effective self-management strategies for optimal control and complications prevention. Self-management interventions have become a crucial component in the management of hypertension. Therefore, this review aimed to determine effective self-management strategies for hypertensive patients.Articles were searched from four databases, namely Science Direct, Ebsco (MEDLINE), Proquest, Pubmed and Sage Journals based on PRISMA guidelines. The search included articles published in English between 2013 and 2022. A key term search strategy was adopted using “self-management interventions”, “nursing interventions”, “experimental study” and “hypertensive patients” to identify relevant studies.The results showed that self-management interventions have been proven to have positive effects on various aspects of hypertension self-management, including blood pressure monitoring, disease knowledge, medication adherence, and lifestyle modifications. These interventions can be delivered through technology-based platforms. Moreover, there are different types of self-management interventions for hypertensive patients, including individual and group approaches, the use of technology, nursing theory, and interventions based on the cultural aspects of patients.To conclude, as professionals, nurses should be able to determine which self-management strategies are suitable for the conditions and requirements of patients.

Upregulation of Insulin-like Growth Factor-I in Response to Chemotherapy in Children with Acute Lymphoblastic Leukemia.

The treatment of childhood cancer is challenged by toxic side effects mainly due to chemotherapy-induced organ damage and infections, which are accompanied by severe systemic inflammation. Insulin-like growth factor I (IGF-I) is a key regulating factor in tissue repair. This study investigated associations between the circulating IGF-I levels and chemotherapy-related toxicity in pediatric acute lymphoblastic leukemia (ALL). In this prospective study, we included 114 patients (age: 1-17 years) with newly diagnosed ALL treated according to The Nordic Society of Paediatric Haematology and Oncology (NOPHO) ALL2008 protocol between 2013 and 2018. The patients' plasma levels of IGF-I, and the primary binding protein, IGFBP-3, were measured weekly during the first six weeks of treatment, including the induction therapy. The patients' systemic inflammation was monitored by their C-reactive protein (CRP) and interleukin (IL)-6 levels and their intestinal epithelial damage by their plasma citrulline levels. IGF-I and IGFBP-3 were converted into sex-and age-adjusted standard deviation scores (SDS) using 1621 healthy children as reference. At ALL diagnosis, IGF-I levels were decreased (median (quartiles): -1.2 SDS (-1.9 to -0.5), p = 0.001), but increased significantly following the initiation of chemotherapy, peaking on day 8 (0.0 SDS (from -0.8 to 0.7), p < 0.001). This increase correlated with the levels of CRP (rho = 0.37, p < 0.001) and IL-6 (rho = 0.39, p = 0.03) on day 15, when these markers reached maximum levels. A larger IGF-I increase from day 1 to 15 correlated with a slower recovery rate of the intestinal damage marker citrulline from day 15 to 29 (rho = -0.28, p = 0.01). Likewise, IGFBP-3 was reduced at diagnosis, followed by an increase after treatment initiation, and was highly correlated with same-day IGF-I levels. This study demonstrates a chemotherapy-induced increase in IGF-I, with a response that appears to reflect the severity of tissue damage and systemic inflammation, preceding CRP and IL-6 increases. IGF-I may have potential as an early reactive biomarker for acute toxicity in patients with ALL.

A retrospective analysis of the relationship between dermatomyositis‐associated interstitial lung disease and disease duration, age, arterial blood gas pH, and serum Cl− levels

AbstractBackgroundDermatomyositis‐associated interstitial lung disease (DM‐ILD) represents a severe and insidious complication of dermatomyositis (DM). The study aimed to investigate the association between DM‐ILD and arterial blood gas indices, serum ion levels, and the timing of interstitial lung disease onset, with the goal of identifying potential predictors for DM‐ILD.MethodsThe investigation involved the collection of basic data from 89 patients with DM hospitalized at the Chinese PLA General Hospital between January 2019 and April 2022, and 43 normal control patients hospitalized for physical examinations during the same period. Analyses were conducted to explore the relationship between DM‐ILD, arterial blood gas indices, disease duration, and serum ions. A regression model to predict DM‐ILD was developed using these indices, and a receiver operating characteristic curve was generated.ResultsSignificant differences were observed in pH and PaO2 between the control group and the disease group (p &lt; 0.05). The DM group exhibited higher levels of pH, actual bicarbonate, and base excess (BE) compared with the control group. In contrast, pH and BE levels were lower in the DM‐ILD group than in the DM group, with these differences being statistically significant (p &lt; 0.05). Interstitial lung disease was correlated with the duration of the disease and pH levels (p &lt; 0.05). The cutoff values for age, disease duration, pH, and Cl− were 55.5 years, 5.5 years, 7.432, and 101.5 mmol/L, respectively. The model demonstrated a prediction sensitivity and specificity for DM‐ILD of 0.809 and 0.722, respectively, with an area under the curve of 0.809.ConclusionArterial blood gas analysis and serum Cl− levels may assist in predicting DM‐ILD. A combined monitoring approach involving arterial blood gas pH, disease duration, age, and serum Cl− levels could enhance the accuracy of DM‐ILD predictions and hold significant clinical evaluation potential.

Abstract 13: Vascular Chemerin, Particularly from PVAT, contributes to Norepinephrine and Serotonin-Induced Vasoconstriction and Vascular Stiffness in a Sex-Dependent Manner

The adipokine chemerin has been implicated in healthy blood pressure maintenance and adiposity-associated hypertension, evidenced by falls in mean arterial pressure after administration of an antisense oligonucleotide against chemerin in Dahl SS rats. Circulating levels of chemerin are positively associated, in humans, with hypertension and aortic stiffening—a blood pressure-independent risk factor of cardiovascular disease. While chemerin’s role in blood pressure is observed in whole animals, mechanisms of chemerin’s influence on vascular health and disease remain unknown. Chemerin causes direct vasoconstriction through its main receptor Chemerin1 and indirect vasoconstriction by amplifying electrical field stimulation-induced contraction. We identified chemerin production at the vasculature—the blood vessel and its perivascular adipose tissue (PVAT)—and are working to discover the mechanistic role of vascular chemerin in blood vessel function and disease. Using RNAScope®, QPCR, isometric contractility, western blot, and in vivo imaging, we test the hypothesis that vascular chemerin increases arterial contractility through Chemerin1 and plays a role in aortic stiffening. RNAScope® probes detected CMKLR1 expression in the tunica media and PVAT of the thoracic aorta. QPCR revealed Rarres2 expression was higher in the PVAT, and CMKLR1 expression was higher in the media. Chemerin1 antagonism via the selective inhibitor CCX832 (1μM) significantly reduced maximal contraction to both norepinephrine (NE) and serotonin (5-HT) (see figure), but not angiotensin II, in the male rat +PVAT groups. This supports that PVAT-derived chemerin plays a role in sympathetic stimulation of the vasculature. Interestingly, in females, this change in contractile response to NE and 5-HT was not observed. Western blot showed that females express significantly lower levels of chemerin protein in PVAT, suggesting PVAT as the primary source of active chemerin. Finally, male, but not female, genetic chemerin knockout Dahl SS rats have lower aortic arch pulse wave velocity than wild types (M WT: 3.7 ± .7 M KO: 1.4 ± .3 F WT: 2.6 ± .5, F KO: 1.5 ± .3 m/s, N=4-6/group), highlighting a role of chemerin in aortic stiffening. Thus, chemerin, sourced by the PVAT, plays a significant role in vascular contractility and aortic stiffening in males. Future work will determine if chemerin’s influence is amplified in adiposity-associated hypertension, where chemerin levels are elevated in both sexes.

Risk factors investigation for different outcomes between unilateral and bilateral chronic rhinosinusitis with nasal polyps patients.

Studies involving chronic rhinosinusitis with nasal polyps (CRSwNP) have mostly focused on bilateral cases, making unilateral CRSwNP inadequately recognized. This study examined the differences in clinical characteristics, outcomes, and risk factors for poor outcomes between unilateral and bilateral CRSwNP to facilitate a better assessment in the two groups. Demographic information, tissue and blood cells, endoscopic scores, Lund-Mackay scores, recurrence rates, and disease control conditions were compared between 310 unilateral and 596 bilateral CRSwNP patients. Furthermore, the stepwise regression multivariate Cox proportional hazard models were performed to generate risk factors for poor outcomes in the two groups. Bilateral cases exhibited higher rates of smoking, AR, and asthma comorbidities, along with higher numbers of tissue eosinophils and blood inflammatory cells when compared to unilateral patients. Endoscopic nasal polyp score, total computed tomography (CT) score (with scores for each sinus cavity), and adjusted CT scores were significantly higher in the bilateral group, except for a markedly higher adjusted maxillary score in the unilateral group. Furthermore, significantly higher proportions of bilateral patients experienced nasal polyp recurrence, uncontrolled status, and most disease control-related symptoms at follow-up. The primary risk factors for poor outcomes were asthma, tissue eosinophils, and total CT score in the bilateral group and blood basophils in the unilateral group. Bilateral CRSwNP patients experience worse disease severity and outcomes than their unilateral counterparts. Primarily, asthma, tissue eosinophils, and total CT score were risk factors for poor outcomes in bilateral CRSwNP patients, with blood basophils in unilateral cases.

Assessment of the vitamin D level and demographic characteristics of children suffering from β-thalassemia in Thi-Qar province

Beta thalassemia is a genetic disorder inherited by autosomal recessive inheritance, is present all over the world . Lifelong transfusions are necessary for people with beta-thalassemia, which can result in an iron buildup in the skin, liver, and kidneys that reduces the production of vitamin D. This study aims to evaluate vitamin D levels, blood groups, and demographic characteristics in beta-thalassemia patients. The current study was conducted at the thalassemia center and hereditary blood disease in Thi-Qar Province with eighty-eight blood samples collected from individuals. It was divided into three groups according to age range, the first group (2-6), the second group (7- 11), and the third group (12- 15). In the current study, there was a significant decrease in Vit-D3 levels among thalassemia patients compared to the control group (p ≤ 0.05) . As for age between the patients group and the control group, the highest proportion of patients in the third age group. As for gender, the results of the study found a non-significant difference at the (P ≤ 0.05 ) level between the patients group and the control group. The most common blood group in thalassemia was O followed by blood groups A, B, and AB. It also shows that the majority of the population was positive Rh.

The relationship between COVID-19 and hyperglycemia: screening and monitoring hospitalized patients

BackgroundElevated blood glucose concentration, also known as hyperglycemia, has been identified as a significant factor influencing the prognosis of COVID-19, alongside the impact of the SARS-CoV-2 infection itself.MethodsThis research is a cross-sectional investigation that examined the relationship between COVID-19 and hyperglycemia in patients admitted to Afzalipour Hospital in Kerman, Iran, from July to September 2021. A standardized data sheet was used to capture demographic data (age, gender) and laboratory information (blood sugar, arterial blood oxygen saturation, and C-reactive protein (CRP)) upon admission.ResultsThe present research evaluated a total of 300 individuals diagnosed with COVID-19, with an average age of 50.19 ± 15.55 years. Among these patients, the majority were male, accounting for 51.67% of the total. Hyperglycemia was seen in 21.67% of patients, but less than 20% had new-onset diabetes. Individuals exhibiting hyperglycemia were typical of advanced age (P < 0.001). Furthermore, there was a slight but statistically significant association between advanced age and elevated blood glucose concentration (R = 0.254, P < 0.001). Gender had no significant impact on the occurrence of hyperglycemia (P = 0.199). There was no significant association between CRP levels and blood glucose concentration (P = 0.524) or the incidence of hyperglycemia (P = 0.473). Although there was no significant disparity in blood oxygen saturation between individuals with or without hyperglycemia (P = 0.06), higher blood glucose concentration was correlated with lower blood oxygen saturation (R = -0.151, P < 0.001).ConclusionConsidering the correlation between blood glucose concentration, advanced age, and disease severity, it is recommended to carefully screen and monitor all COVID-19 patients for hyperglycemia and new-onset diabetes. Effective management of these complications could enhance the control of patients’ overall prognosis and subsequent complications.

Antibiotic Lock Therapy for Port Catheter-Related Infections of Children with Acute Leukemia.

Port catheters facilitate the administration of chemotherapy, antibiotics, blood products, fluid, and parenteral nutrition to pediatric patients with hematological malignancies. However, as its use has become widespread, local and systemic, catheter-related infections have emerged as important causes of morbidity and mortality. In our study, we aimed to evaluate the success of antibiotic lock therapy in port catheter-related infections of pediatric patients followed up with acute leukemia. Port catheter cultures taken from a total of 182 pediatric patients with acute lymphoblastic/myeloblastic leukemia who were followed up at Ankara City Hospital Pediatric Hematology Clinic between August 2019 and August 2023 were evaluated retrospectively. Bacterial growth was identified in 739 port catheter culture specimens of 182 patients. Closure or removal of the port was required in 91, and removal of the port catheters in 49 patients due to port catheter-related infections. Antibiotic lock therapy was started in 56 patients with bacterial growth in the port catheter. With antibiotic lock therapy, port catheter-related infections of 42 patients were eradicated, and their catheters began to be used again. As a result, the port catheter-related infections of 42 of 56 (75%) patients whose ports were closed and also received systemic antibiotic therapy were eradicated, and no infection recurrence was observed. Adding antibiotic lock therapy to systemic antibiotics in pediatric patients may be beneficial in terms of catheter salvage.

The Relationship Between Platelet Indices, Hormonal Status, and Insulin Resistance in Adolescents with Polycystic Ovary Syndrome: A Retrospective Case-Control Study

Aim: This study aimed to investigate the relationship between polycystic ovary syndrome in adolescents, a disease caused by inflammation and insulin resistance that is associated with metabolic disorders, and platelet indices, which provide information about platelet activity. Materials and methods: Patients with oligoovulation, hyperandrogenemia, or clinical signs of hyperandrogenism (hirsutism, acne, etc.) and polycystic appearance with ≥ 20 small follicles ≥ 2∼ 9 mm in diameter in both ovaries on ultrasound according to the newly updated Rotterdam criteria were included in the study with a diagnosis of polycystic ovary syndrome and formed PCOS group. Patients with similar age groups and body mass index (BMI) values who presented to the clinic for non-PCOS symptoms (vaginitis, dysmenorrhea, cystitis), whose complete blood count was checked during hormone testing, and who did not meet the Rotterdam criteria were selected as the control group. Platelet indices found in routine blood count parameters (platelet large cell ratio (P-LCR), platelet distribution width (PDW) and mean platelet volume (MPV)) were analyzed between the two groups. In addition, the relationship between these indices and hormone status and insulin resistance in PCOS patients was analyzed. Patients with diabetes mellitus, hypertension, malignant diseases, cardiovascular diseases, essential thrombocytopenia or other blood diseases and patients taking medication were excluded. Results: In the study of 123 patients, there was no statistically significant difference between the groups in terms of age and body mass index (p:&gt;0.05). When hemogram parameters were compared between the groups, hemogram parameters such as P-LCR (p: 0.002), PDW (p: 0.011) and MPV (p: 0.007), which indicate platelet activity, were statistically significantly higher in the PCOS group. When the data of PCOS patients were analyzed, platelet indices were found to be higher in the group with high insulin resistance (p:

The Relationship between HbA1c, GDP and Disease Duration on the Occurrence of Diabetic Neuropathy at Ibnu Sina Hospital

Diabetes Mellitus (DM) affects over 693 million adults globally by 2045, with complications like neuropathy underscoring the need for effective monitoring. This observational case-control study at Ibnu Sina Hospital, Makassar, explores the relationship between HbA1c levels, fasting blood sugar (GDP), disease duration, and diabetic neuropathy. Analyzing 77 medical records, the study found that most participants were aged 56-65 years, predominantly male, with high rates of uncontrolled HbA1c (80.5%) and GDP (67.5%). Diabetic neuropathy prevalence was 61.0%. Statistical analysis revealed significant correlations between neuropathy and HbA1c levels (p=0.000), GDP (p=0.002), and disease duration (p=0.041). These findings highlight the impact of glycemic control and disease duration on neuropathy in DM patients.

Feasibility of implementing RPA coupled with CRISPR-Cas12a (RPA-Cas12a) for Hepatozoon canis detection in dogs

Hepatozoonosis, caused by the protozoan Hepatozoon canis, is a prevalent blood disease affecting owned and stray dogs and cats. The prevalence of these parasites among companion animals in Thailand remains poorly understood. Diagnosing the old-world form of the disease is challenging due to the wide range of nonspecific clinical signs and the reliance on finding low levels of Hepatozoon gamonts in blood smears for conventional diagnosis. PCR demonstrates high specificity and sensitivity but it requires sophisticated instrumentation. Therefore, we established recombinase polymerase amplification (RPA) coupled with Cas12a for H. canis detection based on 18S rRNA. Our findings showed that RPA-Cas12a using gRNA_H was highly specific to H. canis, without yielding positives for other pathogen species including Babesia species. Even in cases of co-infection, RPA-Cas12a only detected positives in samples containing H. canis. This approach detected minimal amounts of H. canis18S rRNA-harboring plasmid at 10 copies per reaction, whereas plasmid-spiked canine blood enabled detection at a minimal amount of 100 copies per reaction. The performance of RPA-Cas12a was validated by comparing it with quantitative PCR-high resolution melting analysis (qPCR-HRM) and sequencing based on 35 canine blood samples. RPA-Cas12a demonstrated precision and accuracy values of 94 % and 90 %, respectively comparable to qPCR-HRM. Overall, these results indicate that RPA-Cas12a serves as a promising tool for H. canis detection as indicated by comparable performance to qPCR-HRM and is suitable for implementation in small animal hospitals or clinics due to its minimal resource requirements, thereby contributing to effective diagnosis and treatment for infected dogs.

Policy brief of the Belgian Europe’s Beating Cancer Plan mirror group: children, adolescents and young adults with cancer

Children and Adolescents and Young Adults with cancer represent a young population with specific needs, which need to be addressed in a patient- and cancer-driven way. There is an urgent need to support and extend the ongoing initiatives in Belgium. First, multidisciplinary care programmes dedicated to children need to be reviewed, and those for Adolescents and Young Adults need to be developed with close collaboration between paediatric and adult oncology and haematology teams. This needs to be done considering the entire patient journey; from cancer prevention, diagnosis, treatment, rehabilitation, follow-up of late effects, transition pathways between paediatric and adult wards, and palliative care. Second, national haemato/oncology precision programmes adapted to this young population with rare cancers, including infrastructure to manage cancer gene predisposition in CAYAs with cancers and their relatives, needs to be developed. This multi-level plan aims to ensure improved outcome with high quality of care for the young population with cancer in Belgium in line with Europe’s Beating Cancer Plan initiatives.

High genetic diversity of Anaplasma ovis in sheep from Bosnia and Herzegovina.

Ovine anaplasmosis (sensu stricto) is a rickettsial blood disease caused by the tick-borne species Anaplasma ovis. The disease is characterized by mild anemia, fever, and icterus. A more severe clinical presentation is possible in non-endemic areas. There is no existing data on the presence of Anaplasma ovis in Bosnia and Herzegovina. However, given the country's location within the Mediterranean Basin and the recent molecular detection of Babesia ovis, it is plausible that sheep in the region could naturally be infected with this tick-borne pathogen. Blood samples from 81 sheep in the Podrinje and Herzegovina areas were examined by PCR. PCR positivity was found in 38 (46.9%) cases indicating a high number of infected sheep. Mixed infections with Babesia ovis and A.ovis were observed in 63.3% of cases. A higher number of positive sheep was recorded in the area of Herzegovina. Phylogenetic analysis of the gltA, groEL, and msp4 genes of A. ovis revealed numerous genotypes and significant genetic variability. This diversity was not related to geographic origin, tick-borne infection status, or sheep breeding practices in Podrinje and Herzegovina. The data obtained in this study suggest that the emergence of new genotypes and the high genetic variability of A. ovis are driven by specific local and micro-environmental factors.

Changes over the last two decades in Hemophilia A and B management in a Tertiary Care Pediatric Centre

ObjectiveThe treatment of Hemophilia A and B has significantly evolved. Study designwe conducted a retrospective, observational study among patients with HA and HB managed in a Pediatric Hematology and Oncology Unit for almost 22 years for a total of 34 patients. ResultsUntil 2009, more than 80 % of patients were treated only on demand, while in 2022,100 % of patients with moderate and severe disease were receiving continuous prophylaxis. The median age at the start of prophylaxis passed from 10,9 to 1,65 years. In 2022, only one patient was on Standard-half-life-rFVIII, 7 patients were on Extended Half-Life (EHL)-rFVIII/rFIX and 7 patients were on Emicizumab; 1 patient was on Concizumab. The mean ABR passed from 5,7 in the period 2001–2009 to 0,8 in the period 2019–2022. We performed 106 ultrasonographic exams in 19 patients to evaluate the HEAD-US score: a percentage of 45,3 % of these exams revealed a score of 0 and the HEAD-US score resulted inferior in patients who started prophylaxis at an age below the median age at the initiation of prophylaxis. The score showed a tendency to correlate with the number of previous hemarthrosis. In our cohort, the overall prevalence of inhibitors is 0,09 among all patients, and 0,14 in severe HA/HB. 4 patients needed a Central Venous Line (CVL), and 3 patients developed at least one severe complication. Before 2017, we observed 4 cases of life-threatening bleeding in children less than 2 years old not on prophylaxis. Resultsour real-life experience reflects the changes in hemophilia management in the last two decades. In the future, other drugs are expected.

Characterization and Identification of Potential Lactic Acid Bacteria as Biological Control Agent against Ralstonia syzygii subsp. celebesensis of the Banana Blood Disease

Banana is one of the primary fruits cultivated in Malaysia and currently decimated by the emergence of a disease, known as banana blood disease (BBD) which caused by Ralstonia syzygii subsp. celebesensis (Rsc). The BBD has significantly affected the yield and profits of the worldwide banana industry. To date, various approaches including chemical and biological controls have been attempted to manage this disease but none of them succeed in controlling the disease. The uses of lactic acid bacteria (LAB) in managing plant diseases have been reported earlier but little information is available. Therefore, this project is designed to identify and investigate potential plant-associated LAB as biological control agent (BCA) against Rsc by using agar well diffusion method. The inhibition zones of each well were observed after 72h and the isolated LAB that showed inhibition zones were proceed for molecular characterization using PCR amplification followed by gel electrophoresis. The sequences were used for phylogenetic analysis. In addition, each of the potential LAB were used to identify their morphological characterizations and biochemical testing. Throughout the study, the highest inhibition zones of LAB from kimchi and fermented milk achieved a diameter of 21.30 mm and 28.70 mm, respectively. Kimchi isolates showed the highest similarity which is 97% as Lactiplantibacillus plantarum species. Among the fermented milk isolates, the highest similarity which is 98% identified as Lacticaseibacillus paracasei.

Assessing the impact of HBB gene polymorphisms on the risk of beta thalassemia in the population of Diyala Governorate, Iraq

Objective The current research aims to investigate the genetic polymorphisms of the HBB gene and their relationship to the incidence of beta-thalassemia. Methods The study included 30 patients with beta-thalassemia major. Samples were collected during the period between August 2023 and February 2024. Their ages ranged from 2–31 years, in addition to 30 healthy people who did not suffer from hereditary blood diseases as a control group. Their ages ranged from 1–35 years. The exon region of the HBB gene was sequenced using nucleotide sequencing in order to identify the kind and location of mutations that alter the amino acid sequence that makes up the hemoglobin protein. Results The results of DNA sequencing of the exon region of the HBB gene, which consists of 382 base pairs, showed the presence of the rs713040 variant. This variant revealed that the GG genotype and the G allele, and the AA genotype and the A allele, were more frequent in the patient group compared to the healthy group and may be associated with risk. When comparing some physiological variables with the genotypes of the HBB gene between the group of patients and healthy controls at the rs713040 variant site, the results showed that there were significant differences (P&lt;0.001, P&lt;0.05) in the levels of WBC, HB, PLT, PCT, ALP, and Vitamin D in the three genotypes of the variant GG, GA, and AA. Conclusion The findings suggest that the rs713040 variant of the HBB gene may be associated with an increased risk of beta-thalassemia and that there are significant physiological differences between the genotypes of this variant in patients and healthy controls. Further research is needed to understand the underlying mechanisms and the potential clinical implications of these genetic differences.

Bone marrow disease profile in geriatric patients: An institutional study

For the diagnosis and treatment of numerous hematological and non-hematological disorders in patients of all ages, a bone marrow examination is a crucial investigation. Due to the growing elderly population and the paucity of published studies on bone marrow disorders that only affect the elderly, age-related health conditions are becoming more prevalent. In our study, we enrolled elderly patients &amp;#62;60 years old who had a bone marrow examination at GMC Jammu's pathology department.: To study the profile of various hematological and non-hematological lesions diagnosed on Bone Marrow aspiration and/or Trephine biopsy in Geriatric age group 2. To summarize an approach for evaluation of anemia in elderly patients for better management.: The study was conducted in two parts; a Retrospective study for 4 years and a prospective study of 1 year. It included all the patients &amp;#62;60 years of age who had undergone Bone marrow examination in the hematology section of the Department of Pathology.: 200 bone marrow aspirations and 40 trephine biopsies, as well as peripheral blood smears and biopsy imprint smears, were all examined. Aplastic anemia, Megaloblastic anemia, Iron deficiency anemia, chronic disease-related anemia, and ITP were among the non-malignant hematological disorders that affected 50.5% (n=101) of the patients; various hematological malignancies affected 40.5% (n=81) of the patients; and non-hematological malignancies affected 1% (n=2) of the patients. 1% (n=2) of the cases were insufficient, and 7% (n=14) of the cases in which BMA and/or BMB were used for lymphoma staging and follow-up did not show any signs of marrow infiltration. With the growing elderly population in India, it is important to pay more attention to diagnosing and treating easily treatable conditions like anemia as well as enhancing the general health of geriatric patients the elderly, bone marrow aspiration.
