Published on: 6th August, 2021
OCLC Number/Unique Identifier: 9204611613
In this study we describe a method for the detection of biomolecules (in the polypeptide m/z range) directly from the surface of plant leaves by using Mass Spectrometry Imaging. The plant-pathogen interaction between Arabidopsis thaliana and the bacterium Xanthomonas campestris pv. campestris was analyzed by comparing infected and non-infected leaf discs submitted to mass spectrometry. The total surface area of ion distribution was calculated for both samples, revealing 23 ions, out of which 3 showed statistical significance. Although these ions were not identified, the results showed that this approach can be successfully applied for the detection of potential polypeptide biomarkers directly on leaf tissue, which is a major challenge in MALDI-Imaging studies.

Published on: 9th November, 2021
OCLC Number/Unique Identifier: 9335770218
Background: Perinatal asphyxia (PA) which may result in hypoxic ischaemic encephalopathy (HIE) affects four million neonates worldwide and accounts for the death of one million of affected babies. The science of metabolomics has become an area of growing interest in neonatal research, with a potential role in identifying useful biomarkers that can accurately predict injury severity in perinatal asphyxia and HIE.The aim of this review is to look at the evidence of the usefulness of urine metabolomics in predicting outcome in PA/HIE. Methods: The key words used in the advanced search ‘urine metabolomics’ AND ‘perinatal asphyxia’ OR ‘hypoxic ischaemic encephalopathy’, yielded 13 articles. Results: Of the selected thirteen studies, 38% (n = 5) were human studies, 31% (n = 4) were animal studies and 31% (n = 4) were review articles. The studies confirmed the involvement of known pathways in the development of PA/HIE, primarily the Krebs cycle evidenced by accumulation of TCA cycle intermediates (citrate, α-ketoglutarate, succinate) and anaerobic pathways indicated by increased lactate. Other pathways involved include amino acid and carbohydrate pathways. Conclusion: Metabolomic studies so far are promising in highlighting potential biomarker profiles in PA/HIE. Further research is necessary to further clarify the role of identified metabolites in predicting outcome and prognosis in neonates affected by PA/HIE.
Role of perioperative plasma D-dimer in intracerebral hemorrhage after brain tumor surgery: A prospective study
Published on: 2nd August, 2022
Background: Intracerebral hemorrhage (ICH) is one of the most feared complications after brain tumor surgery. Despite several factors being considered to influence bleeding, an increasing number of clinical studies emphasize that hemostatic disorders, developed during surgical aggression and tumor status, could explain unexpected ICH. The objective of this prospective study was to evaluate the influence of perioperative D-dimer levels on ICH after brain tumor surgery. Methods: This prospective, observational, 18-month study, at a single third-level hospital, included all consecutive adults operated on brain tumors and postoperative stay in an intensive care unit. Three blood samples evaluated D-dimer levels (A-baseline, B-postoperative and C-24 hours after surgery). The normal range considered was 0-500ng/ml. ICH, as a primary outcome, was defined as bleeding that generates radiological signs of intracranial hypertension either by volume or by mass effect on the routine CT scan 24 hours after surgery. Other tumor features and hemostasis variables were analyzed. Chi-squared and Fisher’s exact test were used in the inferential analysis for qualitative variables and Wilcoxon and T-Test for quantitative ones. P-value < 0.05 was considered significant for a confidence interval of 95%. Results: A total of 109 patients operated on brain tumor surgery were finally included, 69 male (63,30%) and 40 female (36,70%), with a mean age of 54,60 ± 14,75 years. ICH was confirmed in 39 patients (35,78%). Their average of DDimer was A-1.526,70 ng/dl, B-1.061,88 ng/dl, and C-1.330,91 ng/dl (A p0.039, B p0,223 C p0.042, W-Wilcoxon test). The male group was also associated with ICH (p0,030 X2 test). Of those 39 patients with ICH, 30 in sample A (76,9%), 20 in sample B (51,28%) and 35 in sample C (89,74%) had a D-dimer > 500 ng/dl (p0,092, p1, p0,761 X2 test) and the relative risk of developing a postoperative hematoma in this patients was increased 0,36-fold presurgery, 0,25-fold postsurgery and 0,40-fold 24hours after surgery. D-dimer variation, had no statistical significance (p0,118, p0,195, p0,756 T-test). Platelets and prothrombin activity were associated with D-dimer levels only in sample A (p 0,02 and p 0,20, W Wilson). Conclusion: High levels of perioperative D-dimer could be considered a risk marker of ICH after brain tumor surgery. However, more studies would be worthwhile to confirm this association and develop primary prevention strategies for stroke.
SARS-CoV-2 Omicron and centaurus variants induced lymphocytopenia: A multicenter clinical investigation on 118,561 cases across Pakistan during 2021-2022
Published on: 16th September, 2022
The SARS-CoV-2 pandemic is still ongoing. Previously, several studies have been conducted to investigate laboratory markers as a tool for severity assessment during COVID-19 infections. Biological markers such as Platelet count, D-dimer and IL-6, Lymphocytopenia and others have been used for assessment of severity in COVID-19 disease patients (infected by SARS-CoV-2 Alpha, Beta, Gamma, Delta, Epsilon, and other variants). We observed a significant drop in lymphocyte count among suspected SARS-CoV-2 clinical patients with symptoms of fever, running nose, breathing discomfort, cough, and others during Omicron and Centaurus variants spread in Pakistan. A multicenter, cross-sectional study was conducted from Jan 2021 to Aug 2022, on 118,561 subjects to evaluate hematological abnormalities among suspected patients. Of note, significantly decreased lymphocyte levels (lymphocytopenia) were observed among 43.05% of infected patients. Also, the levels of NA (39.03%), HGB (28.27%), MCV (22.62%), PLT (8.17%), and ALB (4.30%) were also reduced among infected patients. This suggests that lymphopenia can be used as an alternative, cost-effective, early diagnostic biomarker for clinical COVID-19 patients, even before the diagnosis via real-time PCR. In resource-limited countries, the current study is critical for policy-making strategic organizations for prioritizing lymphocytopenia-based screening (as an alternative, cost-effective diagnostic test) in clinical COVID-19 patients, before real-time PCR-based diagnosis.
A proposal of risk indicators for pathological development from hemodynamic simulation: application to aortic dissection
Published on: 28th March, 2023
Cardiovascular diseases are the leading cause of mortality in the industrialized world. Among these diseases, aortic dissection affects the aorta wall and is a surgical emergency with a low survival rate. This pathology occurs when an injury leads to a localized tear of the innermost layer of the aorta. It allows blood to flow between the layers of the aortic wall, forcing the layers apart and creating a false lumen. Endovascular treatment seeks to obliterate the entrances to the false lumen with a covered stent. There are very few studies on the postoperative demonstration of blood flow phenomena in the aortic dissection endovascular treatment. It is crucial to study the hemodynamics of blood in the aorta after an intervention because the new geometrical configuration of the aorta with a stent leads to modifications in blood flow. For the surgeons, the procedure can only be performed empirically, using MRI-4D images to view the postoperative flow of the patient’s blood in the aorta with the stent.This paper aims to present a numerical tool developed from the open-source software FOAM- Extend®, allowing for multiphysics numerical simulations. Using MRI data, a bio-faithful model of the patient-specific case was built. Numerical simulations were performed to predict preoperative and postoperative (endovascular treatment) hemodynamics. The modifications of the flow in the aorta were analyzed focusing on the postoperative perfusions. The results were compared with the corresponding MRI data and have a good qualitative agreement. Biomarkers are calculated to localize possible zones of post-operative pathological developments and recommendations may be suggested to the surgeons.

The disease in moderate to severe cases was characterized by intense inflammation leading to ARDS and hypercoagulable states leading to thrombo-embolism and mortality.Aim: This study aimed to explore the association of inflammatory biomarkers with COVID-19 disease severity in our hospital which became a dedicated COVID hospital during the pandemic.
Research Progress of BTG2 as a Tumor Prognostic Factor
Published on: 21st June, 2023
Cancer is a major public health issue and the main cause of death worldwide. Despite improvements in diagnostic techniques and treatment methods, cancer still seriously affects the quality of life of patients, which cause serious social and economic burdens. Therefore, there is an urgent need to identify potential biomarkers to improve diagnosis, treatment, and prognosis of cancer. BTG2 is a cell proliferation suppressor gene that serves as a tumor suppressor gene in the occurrence and development of various tumors. Many studies have shown that BTG2 can serve as a prognostic marker in various tumors. So, fully tap the potentials of BTG2 as a tumor prognostic marker will bring more possibilities to provide a new method or new diagnostic and therapeutic tool for treating cancer.
Comparative Analysis of HtrA3 and NGAL as Viable Biomarkers for Pre-eclampsia
Published on: 6th July, 2023
Pre-eclampsia is a pregnancy-associated condition, which is characterized by the onset of hypertension and proteinuria. It is one of the leading causes of maternal and neonatal mortality and this affliction has been recorded in around 8% of all pregnancies in the world. In addition to this, the etiopathology of this condition is very less understood and the resources available to diagnose and treat it are limited. Prior studies suggest more than a hundred possible diagnostic biomarkers that could be used to detect this disease early on. However, most of them are not feasible due to several reasons including stability, cost, safety, etc. Here two biomarkers HtrA3 (high-temperature requirement A3) and NGAL (Neutrophil Gelatinase Associated Lipocalin) are selected for the detection of pre-eclampsia, and we compare their efficacy in the detection of pre-eclampsia based on their specificity, ease of use, speed, stage of detection and source (invasiveness). We found that these two biomarkers are efficient under some parameters, and inefficient under others. The scoring system used in the current study suggests that NGAL is a superior biomarker. The results of this study help to develop a stronger understanding of both these biomarkers in the short and long term to classify the biomarkers more efficiently and understand the complicated pathologies of pre-eclampsia.
Assessment and Correlation of Serum Urea and Creatinine Levels in Normal, Hypertensive, and Diabetic Persons in Auchi, Nigeria
Published on: 16th August, 2023
Background/Aim: There has been a progressive rise in the incidence and prevalence of End Stage Renal Disease (ESRD). It has also been observed that the most important reasons for a rapid increase in Chronic Kidney Disease (CKD) patients are the rapidly increasing worldwide incidence of diabetes and hypertension. The present study evaluates the effect of diabetes, hypertension, and comorbid state of hypertension and diabetes (hypertensive-diabetic) on renal function using serum creatinine and urea as markers. Method: A total number of 120 persons were recruited for the research; 30 controls, 30 hypertensive, 30 diabetic, and 30 hypertensive-diabetic persons. Of the 30 control persons, 18 were females and 12 were males; of the 30 hypertensive subjects, 17 were females and 13 were males; of the 30 diabetics subjects, 20 were females and 10 were males, whereas of the 30 hypertensive-diabetic subjects, 21 were females and 9 were males. In total, there were seventy-six (76) females and 44 males. The respondents were pulled from Central Hospital (Auchi) Diabetic and General Clinic and Auchi Polytechnic Cottage Hospital. Verbal consent was sort and questionnaires were used to extract information regarding biodata and patients’ history of diabetes and hypertension. Height and weight were measured, and blood pressure was determined taken. Blood samples were collected into fluoride oxalate and lithium heparin bottle for the assessment of FBS and (serum urea and creatinine) respectively. Results: The mean (±SD) serum creatinine was higher in the hypertensive-diabetic group (2.08 ± 1.06) and declined as follows: diabetic group (1.75 ± 1.01), hypertensive group (1.34 ± 0.96) and control group (0.70 ± 0.14). The mean (±SD) serum urea was also found to be higher in the hypertensive-diabetic group (17.5 ± 9.06) and declined as follows: diabetic group (14.5 ± 6.13), hypertensive group (12.7 ± 6.23) and control group (7.18 ± 5.06). There was a positive correlation between serum creatinine and fasting blood sugar The study also established a positive correlation between serum creatinine and blood pressure but not between serum urea and blood pressure with r values of 0.31 and 0.16 respectively. Conclusion: Good control of blood glucose and blood pressure levels reduces the likelihood of the development of renal impairment which is usually associated with both diabetes and hypertension. Co-morbidity of diabetes and hypertension poses a higher risk of developing renal disease than individual problems of diabetes and hypertension. Serum creatinine and serum urea are important biomarkers for renal impairment hence the two should be monitored on a regular basis for diabetic and hypertensive patients and much more frequently for hypertensive-diabetic patients.
Gene Expression and Functional Analysis in Patients with Acute and Chronic Renal Allograft Rejection
Published on: 3rd November, 2023
Kidney transplantation is the therapy of choice for patients with end-stage kidney disease (ESKD). Nevertheless, the main limitation for long-term graft survival is immune-mediated rejection. Some authors have proposed that differences in immune effector mechanisms are influenced by underlying molecular mechanisms; thereby, the identification of differentially expressed genes in acute or chronic rejection in non-invasive samples such as urine may be essential for the identification of potential biomarkers and biological processes associated with allograft outcomes. Our aim was to explore differences in gene expression and functional categories associated with acute and chronic kidney rejection in blood, biopsy, and urine of kidney transplant patients using RNA-Seq. RNA was isolated and sequenced implementing standard protocols. Analyses were addressed to identify differentially expressed genes (DEGs) and Functional Categories of Gene Ontology comparing between samples. Then we focused on immune genes and pathways to identify their association with the allograft. We identified a significant transcriptional similarity between biopsy and urine, in comparison with blood in acute and chronic rejection. Functional analyses suggested an enrichment of immune processes such as antigen processing and presentation, and regulation of B cell receptor signaling pathway in blood of acute and chronic rejection, respectively. Additionally, we observed an increase in expression of chemokines in biopsy and urine of both outcomes along with an increase in chemokine receptors in blood. Our findings suggest that urine is suitable for identifying potential biomarkers and biological processes related to renal allograft rejection, as it shares a significant number of regulated genes with biopsy.
Kidney Biopsy in Autosomal Dominant Polycystic Kidney Disease
Published on: 19th December, 2023
Proteinuria is an easily quantified biomarker of kidney disease and often a sign of glomerular pathology. Significant proteinuria is uncommon in cystic kidney diseases and should be further evaluated to exclude the presence of another simultaneous kidney disease. While renal biopsy is a valuable part of the diagnostic evaluation of proteinuria, careful consideration of risks and benefits is necessary before proceeding in a patient with bilateral renal cysts. We report the case of a man with Polycystic Kidney Disease (PKD) who was found to have nephrotic-range proteinuria. An ultrasound-guided kidney biopsy revealed evidence of Focal Segmental Glomerulosclerosis (FSGS), which was attributed to hyperfiltration-related injury in the context of extensive kidney cysts. Genetic testing did not reveal a cause of FSGS and showed a variant of uncertain significance in PKD1. We use this case to highlight three important issues that are applicable to patients with PKD: the role of diagnostic evaluation for proteinuria in cystic kidney disease, the feasibility of kidney biopsy despite the presence of bilateral renal cysts, and the roles and limitations of genetic testing in cystic kidney disease and FSGS.

Published on: 31st January, 2024
With the increase in incidence and prevalence of myeloid neoplasms in India, it has become a necessity to understand its molecular mechanisms, acquisition of genomic alterations, and understand its primary and secondary resistance pathways which ultimately impact the decision of therapeutics. The objective of this review is to investigate the molecular aspects of this disease type and identify the biomarkers that help with diagnosis, risk assessment, prognosis, and selecting the best line of treatment for a specific myeloid neoplasm. Advancements and innovations in molecular technologies from simplest Real-Time PCR to high throughput next-generation sequencing have played a vital role in screening the most common mutations and fusions to the novel and rare. Molecular technologies have helped to enumerate the genomic landscape of myeloid malignancies. The understanding of both- the mechanisms and the technology is a strong combination as it has helped revolutionize precision oncology and helped in giving better therapeutic choices with better clinical outcomes. The importance of cellular morphology, clinical symptoms, and molecular pathology in assessing the risk of myeloid malignancies is emphasized and summarized in the review. The review concludes that understanding molecular pathogenesis can be improved by using clinical-pathological-molecular strategies for diagnosis and therapy decision-making.
Biomarkers for High Metabolic Burden in Neurologic Disease
Published on: 15th February, 2024
Neurologic diseases are recognized to have multifactorial origins well beyond mere genetic predisposition. Nutritional burdens have been identified to contribute to neurodegeneration. Healthy diets are becoming increasingly appreciated to potentially play key roles in both the developing and developed world of reducing incidences of neurologic diseases, while unhealthy diets are acknowledged to be contributing to their rise.
Association of Cytokine Gene Polymorphisms with Inflammatory Responses and Sepsis Outcomes in Surgical and Trauma Patients
Published on: 19th February, 2024
Sepsis, a life-threatening condition triggered by infection, poses a significant healthcare challenge with high mortality rates. The interplay between genetics and the immune response in sepsis, particularly in surgical and trauma patients, is complex and critical. Genetic polymorphisms, particularly in cytokine genes like TNF-α, IL-6, and IL-8, have been extensively studied for their influence on sepsis susceptibility, severity, and outcomes. Polymorphisms can alter gene expression and cytokine production, leading to variations in immune responses. Studies have also explored polymorphisms concerning sepsis in genes encoding CD86, TLR4, and SIRT6. This review highlights the association between genetic polymorphisms and inflammatory responses, focusing on their impact on sepsis outcomes in surgical and trauma patients. Genetic variations play a significant role in sepsis risk, severity, and prognosis, with potential implications for personalized therapeutic strategies. Biomarkers such as cytokine gene polymorphisms may aid in predicting sepsis risk and guiding treatment decisions. Complementary therapies like acupuncture and novel biomarkers like microvesicles carrying mitochondrial content provide additional avenues for personalized sepsis management. Furthermore, multiomics approaches offer promise in predicting postoperative outcomes in surgical patients. Understanding the genetic basis of sepsis is essential for improving prevention, diagnosis, and treatment, ultimately leading to better clinical outcomes. Combining genomics, bioinformatics, and clinical expertise, precision medicine can revolutionize sepsis management by tailoring interventions to individual genetic profiles, thus enhancing patient care and outcomes.
Rida Herbal Bitters Improve Cardiovascular Function in High-fat Diet/Streptozotocin-induced Diabetic Rats
Published on: 28th February, 2024
Background: Effective medication to manage diabetes mellitus-related organ complications with minimal adverse drug toxicity is still in pursuit by scientists worldwide. This study investigated the cardio-protective of Rida herbal bitter (RHB) in a high-fat diet/streptozotocin (STZ)-induced diabetic rats.Methods: Thirty-two matured male Wistar rats (250 ± 20g) were used. The animals were fed with high-fat diet (HFD) for 6 weeks before diabetes induction. A single dose of (35 mg/kgb.wt) freshly prepared STZ was injected intraperitoneally to induce diabetes. The animals were allocated into four groups, 8rats/group. Group I: control; Group II: HFD/STZ-induced diabetic rats; Groups III & IV: HFD/STZ-induced diabetic rats treated with 0.3 ml RHB & 200 mg/kgb.wt metformin respectively. At the end of the experiment, the animals were sacrificed, blood was sample collected via cardiac puncture and the heart was excised and homogenized. The blood samples and cardiac homogenates tissue were centrifuged to retrieve clear supernatant plasma for biochemical assay.Results: Diabetic rats exhibited significant (p < 0.05) elevated blood glucose, insulin, glycated hemoglobin (HbA1c), cardiac biomarkers, lipid profile, malondialdehyde (MDA), pro-inflammatory cytokines, food, and water intake levels with a reduction in body weight, cardiac antioxidant activity, and total protein. RHB administration significantly (p < 0.05) diminished the blood glucose, insulin, HbA1c, cardiac biomarkers, MDA, pro-inflammatory cytokines, lipid profile, food, and water intake, and improved the body weight cardiac antioxidant activity, and total protein.Conclusion: Rida herbal bitter possesses a cardio-protective effect from this study and could be a better alternative medication for managing diabetes and its related cardiovascular complications.
Contrast-enhanced Susceptibility Weighted Imaging (CE-SWI) for the Characterization of Musculoskeletal Oncologic Pathology: A Pictorial Essay on the Initial Five-year Experience at a Cancer Institution
Published on: 2nd April, 2024
Susceptibility-weighted imaging (SWI) is based on a 3D high-spatial-resolution, velocity-corrected gradient-echo MRI sequence that uses magnitude and filtered-phase information to create images. It SWI uses tissue magnetic susceptibility differences to generate signal contrast that may arise from paramagnetic (hemosiderin), diamagnetic (minerals and calcifications) and ferromagnetic (metal) molecules. Distinguishing between calcification and blood products is possible through the filtered phase images, helping to visualize osteoblastic and osteolytic bone metastases or demonstrating calcifications and osteoid production in liposarcoma and osteosarcoma. When acquired in combination with the injection of an exogenous contrast agent, contrast-enhanced SWI (CE-SWI) can simultaneously detect the T2* susceptibility effect, T2 signal difference, contrast-induced T1 shortening, and out-of-phase fat and water chemical shift effect. Bone and soft tissue lesion SWI features have been described, including giant cell tumors in bone and synovial sarcomas in soft tissues. We expand on the appearance of benign soft-tissue lesions such as hemangioma, neurofibroma, pigmented villonodular synovitis, abscess, and hematoma. Most myxoid sarcomas demonstrate absent or just low-grade intra-tumoral hemorrhage at the baseline. CE-SWI shows superior differentiation between mature fibrotic T2* dark components and active enhancing T1 shortening components in desmoid fibromatosis. SWI has gained popularity in oncologic MSK imaging because of its sensitivity for displaying hemorrhage in soft tissue lesions, thereby helping to differentiate benign versus malignant soft tissue tumors. The ability to show the viable, enhancing portions of a soft tissue sarcoma separately from hemorrhagic/necrotic components also suggests its utility as a biomarker of tumor treatment response. It is essential to understand and appreciate the differences between spontaneous hemorrhage patterns in high-grade sarcomas and those occurring in the therapy-induced necrosis process in responding tumors. Ring-like hemosiderin SWI pattern is observed in successfully treated sarcomas. CE-SWI also demonstrates early promising results in separating the T2* blooming of healthy iron-loaded bone marrow from the T1-shortened enhancement in bone marrow that is displaced by the tumor.SWI and CE-SWI in MSK oncology learning objectives: SWI and CE-SWI can be used to identify calcifications on MRI.Certain SWI and CE-SWI patterns can correlate with tumor histologic type.CE-SWI can discriminate mature from immature components of desmoid tumors.CE-SWI patterns can help to assess treatment response in soft tissue sarcomas.Understanding CE-SWI patterns in post-surgical changes can also be useful in discriminating between residual and recurrent tumors with overlapping imaging features.
Assessment of Redox Patterns at the Transcriptional and Systemic Levels in Newly Diagnosed Acute Leukemia
Published on: 29th April, 2024
Background: Acute leukemia is the result of clonal transformation and proliferation of a hematopoietic progenitor giving rise to poorly differentiated neoplastic cells. Reactive oxygen species play a role in maintaining the quiescence, self-renewal, and long-term survival of hematopoietic stem cells, but it is unclear how they would affect disease onset and progression. The aim is to evaluate, at the transcriptional and systemic level, the oxidative-inflammatory status in newly diagnosis acute leukemia patients. Methods: Seventy acute leukemia patients [26 acute lymphoblastic leukemia (ALL), 13 Acute Promyelocytic Leukemia (APL), and 31 Acute Myeloid Leukemia (AML)] and forty-one healthy controls were analyzed. Malondialdehyde and catalase activity were evaluated. Gene expression of NRF2, SOD, PRDX2, CAT, IL-6, and TNF-α was analyzed by real-time PCR.Results: Malondialdehyde concentration was similar in all groups studied. Catalase activity was significantly higher in AML and APL patients compared to controls, while ALL showed similar activity to the healthy group. NRF2, CAT, and PRDX2 expression levels were similar between groups, SOD expression was downregulated in all acute leukemia patients. TNF-α expression was lower in AML groups than in healthy individuals, and IL-6 mRNA expression was downregulated in ALL and APL.Conclusion: This is the first report that correlates transcriptional and systemic parameters associated with the oxidative inflammatory status in newly diagnosed acute leukemia. Some of the parameters evaluated could be used as biomarkers in the selection of an effective therapeutic strategy and will open new directions for the follow-up and evolution of this disease.

Published on: 15th May, 2024
Background: The unwanted adverse toxicity displayed by synthetic antidiabetic medicine leads to the search for effective natural medicine to combat diabetes complications. This study investigated the cardioprotective of Anacardium occidentale nuts methanolic in high-fat diet (HFD)/streptozotocin (STZ)-induced diabetic rats.Materials and methods: Forty male adult Wistar were used and fed with HFD for 6 weeks before diabetes induction. The rats were grouped into 5 groups, 8 rats/group. Group I: normal control; Group II: diabetic control; Group III & IV: diabetic rats + 100 mg/kgb.wt & 200 mg/kgb.wt Anacardium occidentale nuts methanolic extract; Group V: diabetic rats + 200 mg/kgb.wt metformin. The rats were sacrificed on the experiment’s last day, blood samples were collected and the hearts were isolated for biochemical parameters estimation.Results: Food intake, water intake, plasmas insulin, Fasting Blood Glucose (FBG), glycosylated hemoglobin (HbA1c), cardiac enzymes, lipid profile, inflammatory cytokines, malondialdehyde, fibrotic marker, caspase-3 in cardiac of diabetic rats were elevated (p < 0.05) significantly. Body weight, cardiac antioxidant, and anti-apoptotic marker levels diminished (p < 0.05) significantly in diabetic rats. 100 mg/kgb.wt & 200 mg/kgb.wt of Anacardium occidentale nuts methanolic extract administration significantly suppressed the plasma insulin, FBG, HbA1c, cardiac lipid profile, cardiac enzymes biomarker, cardiac inflammatory cytokines, cardiac malondialdehyde, cardiac fibrotic marker, cardiac caspase-3, food intake & water intake and increased the body weight, cardiac antioxidant & cardiac anti-apoptotic marker in the diabetic rats.Conclusion: Anacardium occidentale nuts attenuate cardiac injury in diabetes. It could be a natural medicine to manage diabetes-cardiovascular complications.
Fatal Immune Checkpoint Inhibitor-associated Myocarditis Mimicking Infiltrative Cardiomyopathy in a 54-year-old Woman with Metastatic Melanoma
Published on: 4th June, 2024
Introduction: Immune checkpoint inhibitors (ICI) have significantly improved cancer treatment outcomes, but cardiovascular complications such as ICI-associated myocarditis are a major concern. Diagnosing myocarditis requires integrating biomarkers, electrocardiogram (EKG), cardiac imaging, and endomyocardial biopsy. We present a case illustrating these diagnostic challenges, involving a female patient treated with pembrolizumab who developed fatal acute myocarditis mimicking infiltrative cardiomyopathy.Case report: A 54-year-old woman with mucosal melanoma, treated with pembrolizumab, was hospitalized in May 2023 due to dyspnea and elevated troponin levels. Initial cardiac workups were normal, but subsequent tests revealed borderline cardiac magnetic resonance imaging findings. In late May 2023, the patient was admitted with worsening dyspnea, elevated NT-pro-BNP, and severe hyperlactatemia. Imaging and endomyocardial biopsy confirmed acute myocarditis with atypical presentation, mimicking infiltrative cardiomyopathy. Despite aggressive immunosuppressive therapy, the patient’s condition deteriorated, resulting in cardiogenic shock and death seven days post-admission.Conclusion: This case underscores the diagnostic and management challenges of ICI-associated myocarditis, particularly with atypical presentations. It highlights the need for vigilant, comprehensive monitoring and further research to improve diagnostic and therapeutic strategies for managing these severe side effects in patients undergoing ICI therapy.
Molecular Mechanisms and Potential Predictive Biomarkers in Advanced Non-small Cell Lung Cancer: A Summary of Current and Future Trends
Published on: 27th June, 2024
Non-small-cell lung cancer (NSCLC) accounts for 85% of lung cancer cases and is associated with different risk factors (smoking habits, gender, and age). In this scenario, many studies have been conducted to pursue improvement of survival, faster and better therapy response, reduced adverse events, and expanded available therapies and treatments against tumor resistance to drugs. These studies have focused on defining the most prevalent NSCLC biomarkers (EGFR, HER2, ALK, MET, ROS1, BRAF, KRAS G12C, HER3, NTRK, and NRG1) and their actionability. It is noteworthy that expressed kinase receptors can have overlapping mechanisms of activation of different pathways (JAK-STAT, MAPK, PI3K-AKT-mTOR, and PLC-c), which can lead to the same outcome of cell proliferation, migration, and survival resulting in increased tumor resistance to treatment. This review provides an overview of the latest findings regarding NSCLC treatment, emphasizing particular biomarkers and potential molecularly altered pathways implicated as targeted therapies. Additionally, it explores the clinical significance of the proposed treatments, their implication on progression-free survival, ongoing clinical trials, and their perspective of evolution so far.
