Mechanism of Action and Validation of the Traditional Medicinal use of Grewia Tenax Fruits in Sudan to Encounter Iron Deficiency Anemia
Published on: 27th December, 2023
Introduction: In Sudan, Grewia tenax fruits, are known commonly as Goddaim. The fruit’s pericarp is used traditionally for a long time as a juice or a porridge to treat iron deficiency anemia (IDA). Traditional Goddaim users have a very strong belief in its effectiveness. However, the pattern of hemoglobin improvement follows an initial fast increase followed by a decline upon continuing its use. Some previous studies have attributed its effect to high iron content, while the iron quantity was too small. This work attempts to find an explanation for its mechanism of action by screening the fruit extract and its respective fractions for secondary metabolites, minerals, vitamins, and fibre. Methods: Entailed three methodologies: Chemical analysis to identify quantified minerals, ascorbic acid and non-digestible fibers, Phytochemical Analysis to separate and identify secondary metabolites using high-performance liquid chromatography coupled to tandem mass spectrometry (HPLC-MS-MS technique), and estimation of radical scavenging activities of crude fruit extract and its respective chloroform and ethyl acetate fractions by inhibition of the 2,2-diphenylpicrylhydrazyl (DPPH).Results: Ascorbic acid and indigestible fibres were revealed in the aqueous extract. Secondary metabolites were flavonoids (e.g., quercetin, kaempferol), organic acids (e.g., ferulic acid, chlorogenic acid), β-carboline alkaloids (e.g., 3-hydroxy-tetrahydroharman) identified in the chloroform, and ethyl acetate fractions. The in vitro antioxidant activity of G. tenax fruit extract was confirmed spectrophotometrically. Conclusion: It can be concluded that the initial enhancement of iron absorption through ascorbic acid and fibres, followed by iron uptake inhibition, could be explained by iron chelation by the chelators in the fruits. This paradoxical effect may qualify G. tenax fruits as a safety gauge for improving haemoglobin levels without compromising iron excess once iron stores are filled by keeping the oxidative stress in check. This may present G. tenax fruits as a good and safe remedy that optimizes the treatment of IDA.
Case – Late Presentation of Invasive Keratinizing Squamous Cell Carcinoma
Published on: 27th December, 2023
Penile cancer, a rare but highly morbid disease, primarily manifests as squamous cell carcinoma (PSCC) originating from the squamous cells of the glandular and preputial skin. Late-stage diagnosis is common due to social stigma, psychological barriers, and nonspecific initial symptoms, resulting in poor overall survival rates, especially in metastatic cases. This case report illustrates a 38-year-old man with advanced metastatic PSCC, showcasing severe systemic manifestations and delayed presentation of the disease. Despite aggressive treatment options, the patient opted for palliative care, succumbing to the disease months after his diagnosis. Risk factors for PSCC include HPV infection, phimosis, chronic inflammation, and lifestyle factors, with higher prevalence in regions of low socioeconomic status. The psychological and sexual burden of penile cancer is significant, impacting patients’ well-being, mental health, and quality of life. In conclusion, efforts to reduce the stigma associated with penile cancer are crucial to prompt early diagnosis and treatment initiation. Encouraging seeking medical attention for symptoms can enhance the chances of recovery and minimize the need for invasive treatments. Addressing the psychosocial impact of the disease is imperative for holistic patient care.
Aspirin for Primary Prevention of Cardiovascular Disease: What We Now Know
Published on: 9th January, 2024
Cardiovascular disease (CVD), including coronary artery disease and stroke, is the leading cause of death worldwide. Advances in primary and secondary prevention of CVD have improved patient prognoses and outcomes, however, it is imperative that the clinician and patient engage in early risk factor screening and preventive management of modifiable risk factors for CVD. In addition to blood lipid and blood pressure lowering medications, aspirin has been a long-standing therapy targeted to the prevention of CVD based on its antiplatelet and anti-inflammatory activity. However, recent articles and reports on updates to clinical guidelines for the primary prevention of CVD have resulted in confusion about aspirin recommendations. This review aims to assess the latest guidance on aspirin in CVD prevention and how to identify appropriately at-risk patients who may benefit from low-dose aspirin therapy as part of their CVD preventive healthcare choices. Additionally, this review will provide practical application guidance about clinician-patient conversations to clearly explain the benefits and risks of aspirin use and ensure a patient-centric decision to initiate aspirin therapy.
Myeloid Neoplasms: Better Understanding of their Molecular Pathogenesis with Improvised Genomic Testing: A Ray of Hope for Better Clinical Outcomes
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.
Management and Therapeutic Strategies for Spinal Muscular Atrophy
Published on: 29th March, 2024
Spinal muscular atrophy is an autosomal recessive neuromuscular disorder characterized by progressive muscle weakness and atrophy. It is one of the most common single-gene disorders with an incidence rate of approximately 1 in 10,000 live births. The clinical manifestations are progressive hypotonia and muscle weakness due to the degeneration of alpha neurons in the anterior horn cells of the spinal cord and motor nuclei in the lower brain stem. Depending on the severity of the symptoms, SMA has five subtypes. Supportive measures can be offered for respiratory, gastrointestinal, and musculoskeletal complications. Carrier testing for all couples is recommended and this can be done by Multiplex Ligation-dependent Probe Amplification (MLPA). Prenatal diagnosis can be offered to carrier couples. Therapies must be given within the newborn period for maximum benefit and before the loss of motor neurons. It is achieved by identifying the SMA babies through Newborn screening. Several new FDA-approved drugs can reduce the progression of symptoms in SMA. However, they cannot offer a definite cure. Clinical follow-up and Neurological assessment demonstrate that SMA children can attain developmental milestones after receiving treatment, which is never normally attained in untreated cases. In utero SMA treatment with Zolgensma would enhance the survival rate and favorable neurological outcomes in the future. Base editing and Gene editing with CRISPR-Cas technologies to target the mutations and restore functional and stable SMN protein levels are the future hopes for a permanent cure of SMA.
Antibacterial Screening of Lippia origanoides Essential Oil on Gram-negative Bacteria
Published on: 8th April, 2024
Essential oils (EO) are extracted from different plant species and can be present in different plant organs. Rosemary-pepper EO is composed of around 50% to 70% thymol, a phenolic compound proven to be active against fungi and bacteria. The active components present in these compounds can affect the vital functionality of bacterial cells, leading to protein denaturation and cell lysis. Therefore, the present study aims to evaluate in vitro the antibacterial potential of Lippia origanoides EO against gram-negative bacteria. This is an exploratory study, with a technical-experimental procedure, with a quantitative approach, carried out at the Federal University of Campina Grande. The strains used were Pseudomonas aeruginosa ATCC 27853, Proteus mirabilis ATCC 25933, and Escherichia coli ATCC 25922, using concentrations of 1024, 512, 256, and 128 μg/ml using the disc diffusion method in triplicate. After the incubation period, the formation of halos of bacterial growth inhibition was not observed. There are possible causes for the lack of antibacterial activity of the EO concerning the strains of gram-negative bacteria used in the study, including the possibility of not containing components with antibacterial properties in concentrations sufficient for the expected activity at the concentrations tested. Based on the results obtained, the Rosemary-Pepper EO (Lippia organoids) did not demonstrate antimicrobial activity against the gram-negative bacteria used in the study. Therefore, the development of new research with Lippia origanoides essential oil with gram-positive bacteria is suggested.
Knowledge, Attitude, and Practice of Healthcare Workers in Ekiti State, Nigeria on Prevention of Cervical Cancer
Published on: 3rd April, 2024
Purpose: The role of healthcare workers in cervical cancer prevention is pivotal because healthcare workers’ recommendations have been reported to be a key motivational factor for cervical cancer screening among women in Nigeria. Assessing their knowledge, attitudes, and practices on cervical cancer prevention is necessary.Patients and methods: This is a cross-sectional survey involving healthcare workers in Ekiti State, Nigeria. A questionnaire designed for the study was used to obtain data about the knowledge, attitudes, and practices of the healthcare workers. Logistic regression was used to assess the determinants of practice and a p - value of less than 0.05 was taken as statistically significant.Results: Out of 188 participants that completed the study, 165(90.7%) had good knowledge about the prevention of cervical cancer while 24(13.2%) had good practice concerning the prevention of cervical cancer. positive attitude (Odds ratio 1.24, 95% CI 1.14 - 1.35, p < 0.001) increased the odds of good practice.Conclusion: There was no association between the knowledge of cervical cancer prevention and the practice of the healthcare workers. Further research is required to explore the incongruence between knowledge and practice of cervical cancer prevention and its practice.
Oral Cancer Management is not just Treatment! But also, how early Pre-cancerous Lesions are Diagnosed & Treated!!
Published on: 12th April, 2024
Oral Cancer (OC) or squamous cell carcinoma of the oral cavity accounts for approximately 3% of all cancers worldwide, with increased incidence in developing countries. The use of tobacco is directly associated with approximately 80% of oral cancers, especially in older men over 40 years of age. As nearly one-third of the Indian population over 15 years consume smokeless tobacco in one or the other forms, a recent increase has been observed in OC incidence among women and young adults. Lately, the sexual behaviors of young & homosexuals have resulted in the emergence of oropharyngeal cancers due to infection with HPV 16. About 60% of oral cancer cases in India have a five-year survival rate, and this can be improved to 70% to 90% by mere early detection in stages I and II and with various treatment modalities. Despite the well-known benefits of oral cancer screening for the whole population in developing countries remains controversial. It is imperative to address the cultural barriers and societal norms, which limit the acceptability and participation in screening programs in India and many developing countries. This unique challenge of increasing OC morbidity in India and developing countries requires horizontal integration of the health systems with new services focused on cancer control, which gives the best chance for long-term survival, improved outcomes, and affordable care!This article is based on the author’s experience of overseeing 1 case of early detection and 2 cases of delayed diagnosis, outcomes and relevant literature review, and current guidelines for the management of OC.
Exploring the Barriers to Clinic-based Screening for Sexually Transmitted Infections (STIs) among Men in Ghana: A Qualitative Study
Published on: 16th April, 2024
The burden of sexually transmitted infections (STIs) continues to increase with over one million curable STIs occurring daily worldwide. Sex disparity in the rates of testing for STIs can compromise the efforts to reduce the incidence of STIs. The study aimed to explore the barriers to facility-based screening for STIs among men in Ghana. A qualitative exploratory design was employed in this study. Using a semi-structured interview guide, individual in-depth interviews were conducted among purposively sampled men from November 2019 to January 2020. Data saturation was achieved at the ninth participant. Audio-recorded interviews were transcribed verbatim and analysed thematically through Braun and Clarke’s approach. Four themes emerged from the analyses: (1) lack of privacy from healthcare providers, (2) mistrust of healthcare providers, (3) the burden of handling thoughts of positive status, and (4) fear of stigmatisation. These barriers deterred men from seeking clinic-based screening for STIs. The barriers were multi-factorial and a major hindrance to ensuring that people are aware of their STI status through screening and diagnosis. It is imperative to consider these barriers when designing STI screening interventions and policies to help promote facility-based screening for STIs among men in Ghana.
Unlocking the Transformative Power of Synthetic Biology
Published on: 18th April, 2024
Artificial Intelligence (AI) combined with Synthetic Biology has the potential to change the way we approach medicine, agriculture, and manufacturing. AI automates tasks, optimizes experimental designs, and predicts biological behaviours, resulting in more efficient design and engineering of biological systems. However, there are challenges such as data limitations, interpretability issues, and ethical considerations like biosafety and biosecurity concerns that need to be addressed. AI can be used to analyze vast amounts of data and identify patterns. This has led to successful applications of AI in high-throughput screening and biomanufacturing, which can drive innovation and address critical challenges. AI-powered closed-loop systems for real-time monitoring and control of biological processes also show promise in providing real-time feedback and optimizing systems on the fly. Despite these advancements, it's important to consider ethical implications to ensure the responsible development and application of AI in synthetic biology. Proper consideration of challenges and ethical considerations can help leverage the power of AI to drive innovation and tackle pressing societal challenges. Overall, the potential of AI in synthetic biology is significant. By addressing challenges and ethical considerations, we can use them effectively to solve pressing problems.
Breast Cancer in Female
Published on: 22nd April, 2024
Anxiety is also a very common disorder, both in patients and their family members. Anxiety and stress can compromise the quality of life of cancer patients and their families. Feelings of anxiety and anguish can occur at various times of the disease path: during screening, waiting for test results, at diagnosis, during treatment or at the next stage due to concern about relapses. Anxiety and distress can affect the patient’s ability to cope with diagnosis or treatment, frequently causing reduced adherence to follow-up visits and examinations, indirectly increasing the risk of failure to detect a relapse, or a delay in treatment; and anxiety can increase the perception of pain, affect sleep, and accentuate nausea due to adjuvant therapies. Failure to identify and treat anxiety and depression in the context of cancer increases the risk of poor quality of life and potentially results in increased disease-related morbidity and mortality [1]. From all this we deduce the need and importance of dedicated psychological and psychiatric support for these patients within the Breast Unit. The fact that the psycho-oncologist who is dedicated to the care of patients with breast cancer must be an integrated figure in the multidisciplinary team of the Senological Center and not an external consultant is enshrined in the same European Directives that concern the legislation concerning the requirements that a Breast Unit must have in order to be considered a Full Breast Unit (Wilson AMR, et al. 2013).One of the most complex situations you find yourself dealing with is communication with the patient. This communication is particularly complex in two fragile subpopulations that are represented by women. [Menditto L. T (Tirannie) Cancer of the Breast. Am J Psychol & Brain Stud, 2023; 1(1):26-30].
Toxicity and Phytochemical Analysis of Five Medicinal Plants
Published on: 25th April, 2024
Recent studies have shown that long-term uses of herbs have been associated with a rise in morbidity and mortality rates. While most researches are focused on bioactivity investigations, the toxicity of many plants has not been reported. There is a paucity of data on the potential toxicity of the following plants: Harungana madagascariensis (HM), Pterocarpus osun (PO), Phoenix dactylifera (PD), Annona muricata (AM), and Rutidea parviflora (RP). To evaluate the toxicity of the above-mentioned plants; two tests were employed namely: The Brine shrimp lethality test (BSLT) and the Allium cepa test. A correlation between the oral acute toxicity assay in mice and the LC50 obtained from BSLT has been established. Allium cepa test measures the potential genotoxic effects of plant extracts exerted on the root meristem of A. cepa (onions). Plant extracts were administered in concentrations ranging from 100 to 2500 µg/ml to the A. cepa for 72 h to obtain their Mitotic Indices (MI) and EC50. Results of the MI at 2500 µg/ml for HM, PO, PD, AM, and RP were 3.75, 4.96, 5.96, 6.10, and 6.71 while 281.81, 398.11, 501.19, 630.96, and 707.9 µg/ml were obtained as the respective EC50 values. Furthermore, 10-1000 mcg/ml concentrations were administered in the BSLT and the obtained LC50 values were 116.3, 250, 581.5, 581.5, and 750 µg/ml. The toxicity result demonstrated that the five plants were moderately toxic, with RP exhibiting minimal toxicity values and thus potentially having a good safety profile. The phytochemical screening of these plants revealed the presence of some pharmacologically important classes of compounds that are abundant. Several bioactive and toxic compounds were identified in the GC-MS analysis for some of the plants.
GS-MS Profile, Total Flavonoid and Phenolic Contents and Antioxidant Capacity of Leaves of Vitelleria paradoxa c.f. Gaertn
Published on: 1st May, 2024
Vitellaria paradoxa is an important medicinal plant that is used for the treatment of infections such as diarrhea, dysentery, helminthes, gastrointestinal tract, skin, and wounds. This research aims to determine other important uses of the plant leaves and quantify the phytochemicals present in the leaves. The plant leaves were extracted with two solvents (n-hexane and methanol). The phytochemicals were qualitatively and quantitatively analyzed using standard methods. The antioxidant activity was determined using DPPH. In the qualitative phytochemical screening of the methanol extract flavonoids, alkaloids, saponins, and tannins were identified as being present while steroids, anthraquinones, and glycosides were absent. All the screened secondary metabolites were absent in the n-hexane extract. In the GC-MS analysis of the methanol and n-hexane extracts seven compounds were obtained from the methanol extract while a total of twenty-four compounds were obtained from the n-hexane extract. The quantitative determination of the total flavonoid and phenolic contents showed that the leaves high content of flavonoids (91.00 mg quercetin equivalent/g extract) and phenolics (91.39 mg Gallic acid equivalent /g extract). These phytochemicals could be responsible for its high antioxidant activity (79.62%).

Published on: 14th May, 2024
Aim: This study examines the pathological outcomes of chronic liver injuries, with a focus on liver fibrosis. It emphasizes understanding the structural changes within the liver that may lead to cirrhosis and functional impairments, crucial for developing targeted antifibrotic therapies.Methods: Our approach reviews existing literature detailing the use of traditional diagnostic methods—biochemical and serological tests alongside liver biopsies. Additionally, we evaluate the reliability and efficacy of non-invasive techniques such as serological test panels and imaging examinations. These methods are compared to understand their viability as supplementary or alternative diagnostic tools to liver biopsy.Significance: Liver fibrosis, if unmanaged, can progress to severe conditions such as cirrhosis and hepatocellular carcinoma, making it vital to understand its progression and treatment options. This study underscores the need for precise and non-invasive diagnostic tools in the clinical management of liver fibrosis, providing insight into the progression of chronic liver diseases and potential therapeutic targets.Conclusion and future perspectives: The research confirms that while liver biopsy remains the definitive method for staging liver fibrosis, its risks and limitations necessitate the use of enhanced non-invasive diagnostic techniques. These methods have shown promising results in accuracy and are critical for broadening clinical applications and patient safety.It is recommended that the scientific community continue to develop and validate non-invasive diagnostic tools. Enhancing the accuracy and reliability of these tools can provide a cost-effective, accessible, and safer alternative for large-scale screening and management of liver fibrosis in asymptomatic populations. Additionally, integrating advancements in radiologic and serological markers can further refine these diagnostic methods, improving overall patient outcomes.
Design and Construction of Automatic Facemask and Body Temperature Scanning Entry Barrier Machine
Published on: 10th July, 2024
In the context of the global pandemic, public health screening has become paramount as the whole world including developed countries is going through a health crisis. A face mask prevents transpiration and protects against airborne transmitted bacteria or viruses. In the previous scenario of coronavirus, it was critical to eradicate this sickness and preserve our lives. Hence, prevention is better than cure becomes true. Accordingly, many precautionary measures were taken to reduce the spread of the virus. One such method of prevention is wearing a mask and regular monitoring of body temperature. This research dealt with the design and construction of an automatic entry barrier machine that integrates both facemask detection and scanning of individuals exhibiting elevated body temperature functionalities without any human interference. This was accomplished by simulating and synergizing a microprocessor (Raspberry Pi 3 Model B+), a Pi camera, an Infrared Non-contact Temperature sensor, a servo motor, and other components. The barrier arm opens and allows entrance at normal temperature by indicating a green light, displaying ‘allow’ on the LCD, and signaling once or preventing entrance at an elevated unacceptable temperature by indicating a red light, displaying ‘not allowed’ on the LCD, and signaling five (5) times.
Screening for BK Virus Infection in Kidney Transplant Recipients at Mohamed V Military Teaching Hospital
Published on: 25th July, 2024
After kidney transplantation, BK polyomavirus reactivation can manifest as nephropathy in 1% to 10% of patients. PCR testing of urine and blood is commonly used to screen for BK polyomavirus nephropathy. The study aims to detect BK virus infection in kidney transplant patients to prevent tubulointerstitial nephropathy and graft loss. This retrospective study includes 26 patients who underwent kidney transplants between January 2019 and December 2023. We diagnosed BK virus infection by performing real-time PCR on blood and urine samples. BKV DNA was detected in 3 patients. Reducing immunosuppressive therapy led to negative PCR results and favorable clinical and biological outcomes in these 3 patients.
Obstetric Renal Failure: Causes, Prognosis, and Evolution
Published on: 8th August, 2024
The incidence of obstetric acute renal failure remains significant in developing countries. The aim of our study is to define the risk factors involved in the occurrence of ARF during pregnancy or during the immediate postpartum period and to evaluate its evolutionary profile in terms of epidemiology, etiopathogenesis, and therapeutic management over the years in Morocco. This is a retrospective study conducted in the maternal-infant resuscitation service of the Ibn Rochd University Hospital of Casablanca, over the period from January 2020 to August 2023, including 95 patients. The current incidence in our series over this period was 22.2%. The mean age of our population was 33 ± 7.74 years [18-43 years], 67.3% of patients were in the gestational period, compared to 33.7% in the immediate postpartum period. Fourteen patients were primiparous (8.6%), 27.4% had a history of miscarriage, and 10.7% had a history of pre-eclampsia. Oligo-anuria was initially identified in 24 patients. The most frequent etiology was pre-eclampsia (56.7%), followed by hemorrhage (27%) and sepsis (19.3%). The evolution was marked by recourse to hemodialysis in 62% of cases, with a maternal mortality of 26%. The existence of heart disease, the context of pre-eclampsia, and the use of diuretics and vasoactive drugs were significantly correlated with maternal survival. No factor was correlated with secondary recovery from ARF. The development of health structures and the optimization of screening strategies are the keywords for prevention.
Prevalence of Cognitive Impairment in Dialysis Patients in Gauteng Province, South Africa
Published on: 26th August, 2024
Introduction: Cognitive impairment is defined as a new deficit in at least two areas of cognitive functioning. These may include disturbances in memory, executive functioning, attention or speed of information processing, perceptual motor abilities, or language. It has been shown that cognitive impairment is associated with the severity of kidney disease. Methods: The study was a descriptive research design, with participants purposively sampled from the general chronic kidney disease population which included haemodialysis and peritoneal dialysis patients at Steve Biko Academic Hospital in Pretoria, Gauteng Province, South Africa. Hundred and fifty-one participants (76 hemodialysis & 75 peritoneal dialysis patients), 58% were males, and 42% were females aged 19-61 years. To establish the prevalence of cognitive impairment by testing the level of cognition the Mini-Mental State Examination was utilized to provide a brief screening test to quantitatively assess the cognitive abilities and cognitive changes of patients while on dialysis. Results: Ninety-nine percent (99%) of the recruited population reported no cognitive impairment, irrespective of dialysis modality, demographic characteristics, and socio-economic status. Conclusion: Despite the findings highlighting that the majority of the chronic kidney disease population at Steve Biko Academic Hospital reported no cognitive impairment, it is crucial to increase awareness of the potential effects of cognitive impairment on daily activities, quality of life, and treatment adherence. Early detection and management of cognitive impairment can significantly impact the quality of life and adherence to treatment among these patients. Further research is needed to understand the prevalence and impact of cognitive impairment in different populations and to develop effective interventions for its prevention and management.
Proactive Psychiatric Consultation and Hospital Length of Stay in Adults: A Review of the Literature
Published on: 4th October, 2024
According to a 2022 systematic review on the prevalence of psychiatric disorders in general hospitals, it was estimated that approximately one-third of medical inpatients present with a coinciding psychiatric condition. However, other studies have reported that a low rate of patients actually obtain an inpatient psychiatric consult; and even fewer patients receive a consultation when it would not be traditionally indicated. Therefore, we have seen an emergence of the use of Proactive Consultation-Liaison (C-L) Psychiatry across many hospital settings. This model of care utilizes systematic screening for active mental health concerns, proactive interventions tailored to individual patients, team-based delivery, and care integration with primary services to provide psychiatric consultation earlier. This study conducted a focused PubMed search to review the research to date on proactive C-L psychiatry and its impact on hospital length of stay (LOS) in patients over 18 years old. Results show a consequential reduction in average hospital LOS when proactive C-L psychiatry services are used compared to reactive, on-request consultation services. A shortened LOS is seen with this practice when there is a quicker time for consultation or referral. Thus, there is evidence of proactive C-L psychiatry’s success in decreasing average hospital LOS and improving patient care. Additional studies are necessary to determine its significance, as little research to date has been completed on the topic. It is recommended to expand the scope of investigation to different patient populations, including but not limited to pediatrics and patients without an underlying mental health illness.
Exploring Environmental Neurotoxicity Assessment Using Human Stem Cell-Derived Models
Published on: 15th November, 2024
Neurotoxicity is increasingly recognized as a critical factor impacting long-term health, with growing evidence linking it to both neurodevelopmental and neurodegenerative diseases. Pesticides, widely used in agriculture and industry, have emerged as significant contributors to neurotoxic risk, given their capacity to disrupt key neurodevelopmental processes at low exposure levels. As conventional animal models present limitations in interspecies translation, human-derived neuron-based in vitro screening strategies are urgently needed to assess potential toxicants accurately. Human-induced pluripotent stem cells (hiPSCs) offer an innovative and scalable source for human-specific neuronal models that complement traditional animal-based approaches and support the development of predictive assays for neurotoxicity. Recent various stem cell models, including 2D cultures, 3D organoids, and microfluidic systems, are now available, advancing predictive neurotoxicology by simulating key aspects of human neural development and function. With the integration of High-Throughput (HT) and High-Content (HC) screening methodologies, these hiPSC-based systems enable efficient, large-scale evaluation of chemical effects on neural cells, enhancing our ability to detect early biomarkers of neurotoxic effects. Identifying early biomarkers of neurotoxic is essential to developing therapeutic interventions before irreversible damage occurs. This is particularly crucial in the context of developmental neurotoxicity, where early exposure to toxicants can have lifelong consequences. This review specifically presents an in-depth overview of the current progress in hiPSC-derived neural models and their applications in neurotoxicity testing, with a specific focus on their utility in assessing pesticide-induced neurotoxicity. Emphasizing future research priorities, we highlight the potential of these models to transform predictive toxicology, offering more human-relevant assessments and advancing the field toward a more precise evaluation of environmental neurotoxicants.
