ABSTRACT

Retinoblastoma, a rare cancer mostly affecting children, makes up ~3% of childhood cancers in developed countries. However, it is more prevalent in sub-Saharan Africa, where late diagnosis often leads to advanced disease and higher mortality rates. Here, we present a 3-year-old girl presented with leukocoria and esotropia in her left eye for 3 months. Imaging revealed lens calcification and vitreous seeding, classified as group D, stage I. The child underwent enucleation to save her life, and histopathology showed Flexner-Wintersteiner rosette cells. This case underscores the importance of eye exams at birth and during childhood. Primary healthcare providers should recognize symptoms like leukocoria and esotropia to facilitate early diagnosis of retinoblastoma.

ABSTRACT

The ongoing conflict in Gaza has led to severe destruction of the health system and eventually its collapse. Moreover, multiple attacks on health workers were reported which led to obstacles in service delivery. The conflict has led to further humanitarian crises including shortage of food, water sanitation, and hygiene, and outbreaks of infectious diseases. About 2 million of Gaza's population are internally displaced with the majority in Rafah. Rafah's population has increased by 500% in less than four months. This has led to acute food severity in Gaza for the whole of the population. Moreover, the cut of UNRWA aid is expected to further expand the humanitarian crisis as over 2 million of the population depends on the aid.

ABSTRACT

BACKGROUND: The COVID-19 pandemic significantly increased the demand for remote healthcare services delivery, including remote access to medications. This study explored the practices and challenges associated with remote provision of pharmaceutical products and services in Kampala, Uganda. METHODS: A cross-sectional study was conducted from July to September 2022, enrolling 174 out of 198 sampled retail pharmacies. Data was collected using a pre-tested questionnaire on remote service provision, platforms used, products offered, delivery methods, and challenges faced. RESULTS: Over 58% of pharmacies provided remote services, primarily through social media (especially WhatsApp) and phone calls. OTCs and POMs were the most commonly dispensed products remotely. Key challenges identified included high internet costs, labor shortages, poor internet quality, and a lack of specific regulations for remote provision of pharmaceutical products and services. CONCLUSION: The proportion of retail pharmacies providing pharmaceutical products and services remotely is significant in Kampala, but they face challenges that need to be addressed. Regulations are crucial to ensure responsible dispensing practices and rational medicine use. Addressing internet affordability and quality, staffing issues, and delivery logistics is essential for sustainable and effective remote pharmaceutical products and services.

ABSTRACT

A woman in her mid-60s who is a high hypermetrope presented with bilateral eye pain and headache approximately 1 hour after taking a single dose of a widely available decongestant containing paracetamol, guaifenesin and phenylephrine hydrochloride for coryzal symptoms. She had previous successful bilateral peripheral iridotomies performed for narrow angles. At presentation, her intraocular pressures (IOPs) were significantly raised at 72 mm Hg and 66 mm Hg in the right and left eye, respectively, with bilateral corneal oedema. Her IOP was normalised with urgent treatment using 500 mg intravenous acetazolamide, pilocarpine 2%, dexamethasone 0.1% and IOP-lowering drops. She was listed for cataract surgery and was advised to avoid the precipitating agent and other over-the-counter decongestants. This is the first reported case of bilateral angle closure triggered by a decongestant with such a combination of ingredients. Clinicians should be aware of this rare side effect for prompt diagnosis and management.

ABSTRACT

BACKGROUND: Diagnosis of cutaneous hypopigmentation can sometimes be challenging. Dermoscopy may play a role in identifying hypo or-depigmented dermatoses. The aim was to investigate which dermoscopic criteria represent potent indicators for the diagnosis of vitiligo, nevus depigmentosus, pityriasis alba, hypopigmented pityriasis versicolor, idiopathic guttate hypomelanosis, hypopigmented mycosis fungoides (MF), lichen sclerosus et atrophicus and ash leaf hypopigmented macules of tuberous sclerosis, and evaluate their diagnostic accuracy. 168 individuals diagnosed with one of these hypopigmented disorders were evaluated for the presence or absence of predetermined dermoscopic criteria. Evaluation of dermatoscopic characteristics in each condition and analysis for sensitivity and specificity of dermatoscopic diagnosis in these hypopigmented lesions was performed. The starburst pattern, micro-koebnerization, and trichrome pattern were unique to vitiligo diagnosis. Vitiligo had higher comet-tail appearance, perifollicular pigmentation, and perilesional hyperpigmentation than other hypopigmented illnesses. Other hypopigmented lesions had greater incidence of amoeboid pattern, faint or diminished pigment network, islands of pigmentation, ill-defined boundaries, pseudopods, and widespread scaling than vitiligo. Finally, perifollicular scaling, comedo-like openings, blue-gray specks, and fibrotic regions excluded vitiligo. Dermoscopy can help identify common hypopigmented skin lesions and reduce the need for skin biopsy. Nevus depigmentosus, pityriasis alba and idiopathic guttate hypomelanosis were the top three hypopigmented dermatoses that could be diagnosed by dermoscopy with 100% sensitivity. Vitiligo was in the second rank (94.7%), followed by lichen sclerosis et atrophicus (93.3%) then hypopigmented MF at 81.2% sensitivity. Dermoscopy sensitivity was lowest in pityriasis versicolor and ash leaf macules of tuberous sclerosis (52.6% and 46.7%, respectively).

ABSTRACT

The prevalence of nonalcoholic fatty liver disease (NAFLD) is likely to be approaching 38% of the world's population. It is predicted to become worse and is the main cause of morbidity and mortality due to hepatic pathologies. It is particularly worrying that NAFLD is increasingly diagnosed in children and is closely related, among other conditions, to insulin resistance and metabolic syndrome. Against this background is the concern that the awareness of patients with NAFLD is low; in one study, almost 96% of adult patients with NAFLD in the USA were not aware of their disease. Thus, studies on the therapeutic tools used to treat NAFLD are extremely important. One promising treatment is a well-formulated ketogenic diet (KD). The aim of this paper is to present a review of the available publications and the current state of knowledge of the effect of the KD on NAFLD. This paper includes characteristics of the key factors (from the point of view of NAFLD regression), on which ketogenic diet exerts its effects, i.e., reduction in insulin resistance and body weight, elimination of fructose and monosaccharides, limitation of the total carbohydrate intake, anti-inflammatory ketosis state, or modulation of gut microbiome and metabolome. In the context of the evidence for the effectiveness of the KD in the regression of NAFLD, this paper also suggests the important role of taking responsibility for one's own health through increasing self-monitoring and self-education.

ABSTRACT

The focus of the study in this article is analyzing the electrochemical properties of molybdenum disulfide on miscible poly(methyl methacrylate)-poly(lactic acid) blends for supercapacitors. The interaction between molybdenum disulfide and miscible poly(methyl methacrylate)-poly(lactic acid) blends, affinity toward water, surface morphology, and mechanical properties are inspected by Fourier transform infrared spectroscopy, water contact angle, scanning electron microscopy, and universal testing machine, respectively. Among the developed membranes, 0.75 wt% of molybdenum disulfide on poly(methyl methacrylate)-poly(lactic acid) shows better electrochemical performances. It exhibits a maximum specific capacitance of 255.5 F g-1 at a current density of 1.00 mA g-1, maximum energy density of 22.7 Wh kg-1, and maximum power density of 360 W kg-1. A cycle study reveals 92% capacitance retention after 2500 cycles. The designed supercapacitor device shows a maximum specific capacitance of 1240 µF g-1 at a current density of 0.5 µA g-1, maximum energy density of 43 µWh kg-1, and maximum power density of 700 µW kg-1. Flexible membranes of molybdenum disulfide are expected to be a potent combination for supercapacitor applications.

ABSTRACT

BACKGROUND: Female breast cancer stands as the prime type of cancer in the Kingdom of Saudi Arabia (KSA), with a high incidence and mortality rates. This study assessed the burden of female breast cancer in KSA by analyzing and forecasting its incidence, mortality, and disability-adjusted life years (DALYs). METHODS: We retrieved data from the Global Burden of Disease (GBD) about female breast cancer from 1990 to 2021. Time-series analysis used the autoregressive integrated moving average (ARIMA) model to forecast female breast cancer statistics from 2022 to 2026. RESULTS: From 1990 to 2021, KSA reported 77,513 cases of female breast cancer. The age groups with the highest number of cases are 45-49 years, followed by 40-44 years, 50-54 years, and 35-39 years. The analysis also showed fewer cases in the younger age groups, with the lowest number in the less than 20-year-old age group. From 1990 to 2021, KSA reported 19,440 deaths due to breast cancer, increasing from 201 cases in 1990 to 1,190 cases in 2021. The age-standardized incidence rate/100,000 of breast cancer increased from 15.4 (95% confidence interval (CI) 11.2-21.0) in 1990 to 46.0 (95%CI 34.5-61.5) in 2021. The forecasted incidence rate of female breast cancer will be 46.5 (95%CI 45.8-46.5) in 2022 and 49.6 (95%CI 46.8-52.3) in 2026. The age-standardized death rate per 100,000 Saudi women with breast cancer increased from 6.73 (95%CI 6.73-9.03) in 1990 to 9.77 (95%CI 7.63-13.00) in 2021. The forecasted female breast cancer death rate will slightly decrease to 9.67 (95%CI 9.49-9.84) in 2022 and to 9.26 (95%CI 8.37-10.15) in 2026. DALYs increased from 229.2 (95%CI 165.7-313.6) in 1990 to 346.1 (95%CI 253.9-467.2) in 2021. The forecasted DALYs of female breast cancer will slightly decrease to 343.3 (95%CI 337.2-349.5) in 2022 reaching 332.1 (95%CI 301.2-363.1) in 2026. CONCLUSIONS: Female breast cancer is still a significant public health burden that challenges the health system in KSA, current policies and interventions should be fashioned to alleviate the disease morbidity and mortality and mitigate its future burden.

ABSTRACT

BACKGROUND: Africa has consistently had the highest prevalence (70.1%) of H. pylori, and this has led to significant cases of dyspepsia, gastric cancers, and upper gastrointestinal bleeding. However, most studies have used sero-prevalence, which might not give the current state of the infection. Among the tests, the stool antigen test is simple, quick, and effective. The study aimed to determine the feco-prevalence, endoscopic pattern, and associated factors of H. pylori infection among symptomatic adult patients in Northern Tanzania. MATERIALS AND METHODS: A hospital-based, cross-sectional study was conducted from October 2022 to April 2023 among adults attending the gastroenterology clinic at Kilimanjaro Chistian Medical Centre. A systematic random sampling was used to select the participants with indications of undergoing esophagogastroduodenoscopy. Questionnaires, stool and blood samples, and endoscopy were used to collect variable data. Numerical and categorical variables were summarized into narrations and tables. Logistic regression was used to assess the factors associated with H. pylori. RESULTS: The feco-prevalence of H. pylori was 43.4%. Chronic gastritis (51.1%) was the most common endoscopic pattern, whereas duodenal ulcers and gastric ulcers were significantly associated with H. pylori infection. Increasing in age (p <0.001) and blood group (p <0.001) were significantly associated with H. pylori infection in the adjusted analysis. CONCLUSION: The feco-prevalence of H. pylori is high in this setting. H. pylori stool antigen can be used as the initial workup for symptomatic patients before the initiation of proton pump inhibitors. Additionally, due to other causes of dyspepsia, it is advised that H. pylori stool antigen testing be part of the initial evaluation and esophagogastroduodenoscopy be considered in the absence of other alarm symptoms if symptoms persist despite an appropriate trial of medical therapy.

ABSTRACT

Escherichia coli is a major cause of serious infections, with antibiotic resistance rendering many treatments ineffective. Hence, novel strategies to combat this pathogen are needed. Anti-virulence therapy is a promising new approach for the subsequent era. Recent research has examined the impact of sub-inhibitory doses of ascorbic acid and paracetamol on Escherichia coli virulence factors. This study evaluated biofilm formation, protease production, motility behavior, serum resistance, expression of virulence-regulating genes (using RT-PCR), and survival rates in a mouse model. Ascorbic acid significantly reduced biofilm formation, protease production, motility, and serum resistance from 100% in untreated isolates to 22-89%, 10-89%, 2-57%, and 31-35% in treated isolates, respectively. Paracetamol also reduced these factors from 100% in untreated isolates to 16-76%, 1-43%, 16-38%, and 31-35%, respectively. Both drugs significantly down-regulated virulence-regulating genes papC, fimH, ompT_m, stcE, fliC, and kpsMTII. Mice treated with these drugs had a 100% survival rate compared with 60% in the positive control group control inoculated with untreated bacteria. This study highlights the potential of ascorbic acid and paracetamol as anti-virulence agents, suggesting their use as adjunct therapies alongside conventional antimicrobials or as alternative treatments for resistant Escherichia coli infections.

ABSTRACT

BACKGROUND: Orthodontic education, besides some other factors, influences the confidence level of recently graduated dentists to diagnose subjects seeking orthodontic treatment and provide treatment plans. This study aims to explore the factors that influence the confidence level of undergraduate dental students to diagnose subjects seeking orthodontic treatment and provide treatment plans after graduation. METHODS: A qualitative study was undertaken using focus groups and interviews. Purposive sampling was used, focus groups and face to face semi-structured interviews were adopted as the method of data collection. Three focus groups were evaluated including fifth-year undergraduate, postgraduate orthodontic students, and recently graduated general dentists. In addition, eleven interviews were performed with the fifth-year undergraduate students. Data collection ceased upon reaching data saturation, with thematic analysis employed for qualitative data analysis. RESULTS: Six themes and two sub-themes were extracted from the data. More focus on the theory was highly noticed, and most of the participants exhibited a low level of self confidence in extrapolating orthodontic diagnosis and establishing treatment plans after graduation. In addition, they believed that practical teaching sessions mostly deal with wire bending and demanded to expand the clinical orthodontic knowledge to be able to indicate the right diagnosis and initiate proper treatment plans. CONCLUSIONS: Clinical and practical training alongside theoretical foundation represent key factors in orthodontic education required to obtain confidence in orthodontic practice among dental undergraduate students and alumni. The findings help in enhancing undergraduate programs via providing a clinically oriented orthodontic education from student perceptions.

ABSTRACT

Cigarette smoking exacerbates respiratory diseases, while plant-derived polyphenols offer antioxidant and anti-inflammatory benefits. This study explores the effects of Rhoifolin (ROF), a polyphenol from Jordanian Teucrium polium, on lung health in rats exposed to tobacco smoke. Male rats were divided into two groups: one exposed to cigarette smoke (CS), and the other to ROF treatment alongside smoke exposure (ROF/CS). ROF was administered orally for 21 days before smoke exposure. Results showed smoke-induced lung inflammation and oxidative stress, mitigated by ROF treatment. Histological examination revealed smoke-related morphological changes in lung tissue. ROF treatment reduced oxidative stress and inflammation, as evidenced by decreased proinflammatory cytokines. In silico docking demonstrated ROF's potential as an inhibitor. This study suggests the therapeutic potential of ROF and similar polyphenols in mitigating the harmful effects of cigarette smoke on lung health.

ABSTRACT

BACKGROUND: Quantitative myocardial blood flow (MBF) on positron-emission tomography myocardial perfusion imaging is a measure of the overall health of the coronary circulation. The ability to adequately augment blood flow, measured by myocardial blood flow reserve (MBFR), is associated with lower major adverse cardiovascular events and all-cause mortality. The age-specific ranges of MBFR in patients without demonstrable coronary artery disease have not been well established. We aimed to determine the effect of age and sex on MBF in a cohort of patients without demonstrable coronary artery disease. METHODS: Patients who underwent positron-emission tomography myocardial perfusion imaging studies from 2012 to 2022 on positron-emission tomography/computed tomography cameras were included if the summed stress score was 0, the coronary calcium score was 0, and the left ventricular ejection fraction was ≥50%. Those with known coronary artery disease, prior history of coronary intervention, diabetes, heart/kidney/liver transplant, cirrhosis, or chronic kidney disease stage IV+ were excluded. MBF was calculated using a net retention model (ImagenQ, Cardiovascular Imaging Technologies, Kansas City), and quantile regression models were developed to predict MBF. RESULTS: Among 2789 patients (age 59.9±13.0 years, 76.4% females), median rest MBF was 0.73 (0.60-0.91) mL/min·g, stress MBF was 1.72 (1.41-2.10) mL/min·g, and MBFR was 2.31 (1.96-2.74). Across all ages, males augmented MBF in response to vasodilator stress to a greater degree than females but achieved lower absolute stress MBF. Younger males in particular achieved a higher MBFR than their female counterparts, and this gap narrowed with increasing age. Predicted MBFR for a 20-year-old male was 3.18 and female was 2.50, while predicted MBFR for an 80-year-old male was 2.17 and female was 2.02. CONCLUSIONS: In patients without demonstrable coronary artery disease, MBFR is higher in younger males than younger females and decreases with age in both sexes. Age- and sex-specific MBFR may be important in risk prediction and guidance for revascularization and warrant further study.

ABSTRACT

This paper constituted an extension of two previous studies concerning the mathematical development of the grain boundary grooving in polycrystalline thin films in the cases of evaporation/condensation and diffusion taken separately. The thermal grooving processes are deeply controlled by the various mass transfer mechanisms of evaporation-condensation, surface diffusion, lattice diffusion, and grain boundary diffusion. This study proposed a new original analytical solution to the mathematical problem governing the grain groove profile in the case of simultaneous effects of evaporation-condensation and diffusion in polycrystalline thin films by resolving the corresponding fourth-order partial differential equation ∂y∂t=C∂2y∂x2-B∂4y∂x4 obtained from the approximation ∂y∂x2≪1. The comparison of the new solution to that of diffusion alone proved an important effect of the coupling of evaporation and diffusion on the geometric characteristics of the groove profile. A second analytical solution based on the series development was also proposed. It was proved that changes in the boundary conditions of the grain grooving profile largely affected the different geometric characteristics of the groove profile.

ABSTRACT

Context: With increasing labor shortage and production costs, water scarcity and climate change, there is increased interest in ratooning as a green, resource-efficient technology to boost sustainable rice production, especially in China. Since the performance of ratoon rice (regenerating a second crop from the stubble left in the fields after the main harvest) and the impact of agronomic practices on its yield have shown mixed results across the world, a better understanding is needed to determine under which conditions ratoon rice performs well. Objective: The objectives are (i) to quantify variation in rice yield of main and ratoon crops, (ii) to assess genetic variation in and impact of agronomic practices on rice yield, focusing on the yield of ratoon crop and total yield (main and ratoon crops), and (iii) review of economic and environmental benefits of ratoon rice in comparison with single and double rice cropping. Methods: In researching ratoon rice, we compiled a database from 68 studies published from 2000 to 2023. Descriptive data analysis was performed. Results: Studies from non-tropical regions account for about 70%. Large variation exists in the yield of ratoon crop across the studies, with lower yield from the tropics than non-tropics. The ratio of yield of ratoon crop to that of main crop also varied widely from 0.13 to 0.67 with 0.36 and 0.5 in tropics and non-tropics, respectively. The yield of ratoon crop was positively related to the yield of main crop, crop duration and nitrogen fertilizer application rate, which were generally higher in non-tropics. Hybrid varieties out-yielded inbred varieties in both main and ratoon crops in non-tropical regions. Direct seeding and AWD had a positive impact on the yield of ratoon crop. The impact of stubble cutting height was mixed. While agronomic nitrogen use efficiency (AEN) during entire ratoon rice cropping was similar to that reported for single rice cropping in previous studies, AEN for ratoon crop in tropical regions tended to be lower than those from previous studies on single rice cropping. Ratoon rice cropping reduced labor input and production cost and increased net economic return compared with double rice cropping. Conclusions: We propose a research agenda, with the focus on improvement of genetic and agronomic practices to explore the potential of ratoon rice cropping, especially in the tropics. Implications: This study provides insight into the progress in ratoon rice research over the past two decades globally, and specifically in the tropics.

ABSTRACT

The QT interval, an electrocardiographic temporal representation of the ventricular depolarization and repolarization, is an integral parameter that must be carefully evaluated to gather critical information regarding electrical instability that may cause malignant ventricular dysrhythmias or sudden cardiac death. The QT interval is affected by several inheritable and acquired factors, such as genetic mutations, electrolyte disturbances, and medication interactions. We strongly believe that prompt and accurate recognition of any QT interval abnormalities is critical in many clinical settings. This concise review article highlights the importance of accurate measurement of the QT interval, enhances understanding of the most prevalent factors yielding abnormalities within the QT interval and the prognostic value of the QT interval, as well as provides several key practical reminders for healthcare professionals to strengthen our clinical practice.

ABSTRACT

Introduction: Stress and pain are high among patients undergoing hemodialysis. Benson's Relaxation technique affected a wide range of physical and psychological signs and symptoms among patients undergoing hemodialysis. Objective: To evaluate the effectiveness of Benson's Relaxation Technique in reducing stress and pain among patients undergoing maintenance hemodialysis. Materials and Methods: A systematic review of randomized controlled trials was conducted. A systematic literature search was carried out from 2000 to 2023. Searched databases included EBSCO-Host "Academic Search, Cochrane, CINAHL, Health Business, MEDLINE, Psychology and Behavioral Sciences, SPORTDiscus", PubMed, Ovid, and Google Scholar. The Preferred Reporting Items for Systematic Review and Meta-Analysis guidelines were conducted. RCTs were critically appraised using the Cochrane's Risk of Bias Tool. Four RCTs met the inclusion criteria and included in this review since they were applicable to practice. Results: Four randomized controlled trials were identified supporting the use of Benson's relaxation technique as a nursing treatment in managing stress and pain among patients undergoing maintenance hemodialysis, as it achieved a significant decrease in stress and pain scores. The overall quality of the randomized controlled trials was judged to be low to relatively moderate. Conclusions: Most of the randomized controlled trials lacked details on intervention adherence. It is recommended to conduct additional longitudinal randomized controlled trials in different countries with bigger sample sizes, to provide more evidence for generalizing outcomes.

ABSTRACT

BACKGROUND: Peripheral insulin resistance and compromised insulin secretion from pancreatic ß-cells are significant factors and pathogenic hallmarks of diabetes mellitus (DM). NF-κß/TLR-4 and SERCA/Ca2+ pathways have been identified as potential pathways regulating insulin synthesis by preserving pancreatic ß-cell functioning. The current study aimed to evaluate the therapeutic effect of aged garlic extract (AGE) against DM in a streptozotocin (STZ)-induced rat model with particular emphasis on pancreatic ß-cell functioning. METHODS: AGE was characterized by gas chromatography-mass spectrometry (GC-MS), Fourier-transform infrared spectroscopy (FTIR), and scanning electron microscopy (SEM) to evaluate its physio-chemical characteristics followed by in-vitro anti-diabetic and antioxidant potential. This was followed by the induction of DM in laboratory animals for investigating the therapeutic action of AGE by evaluating the role of NF-κß/TLR-4 and the SERCA/Ca2+ pathway. The parameters assessed in the present experimental setup encompassed antioxidant parameters, metabolic indicators, insulin concentration, intracellular calcium levels, apoptotic markers (CCK-8 and Caspase Glo-8), and protein expression (P-62 and APACHE-II). RESULTS: AGE characterization by SEM, GC-MS, and X-ray diffraction (XRD) revealed the presence of phenylalanine, alliin, S-allylmercaptocysteine (SAMC), tryptophan, 1-methyl-1,2,3,4-tetrahydro-ß-carboline-3-carboxylic acid as major bioactive constituents of AGE. Metabolic studies, including intraperitoneal glucose tolerance test (IPGTT), revealed significantly lower blood glucose levels in the AGE group compared to the disease control group. In contrast, the intraperitoneal insulin tolerance test (ITT) exhibited no significant difference in insulin sensitivity between the AGE supplementation group and the DM control group. Interestingly, AGE was found to have no significant effect on fasting glucose and serum insulin levels. In contrast, AGE supplementation was found to cause significant hypoglycaemia in postprandial blood glucose and insulin levels. Importantly, AGE causes restoration of intracellular Ca2+ levels by modulation of SERCA/Ca2 functioning and inhibition NF-κB/TLR-4 pathway. AGE was found to interact with and inhibit the DR-5/ caspase-8/3 apoptotic complex. Furthermore, microscopic studies revealed degeneration and apoptotic changes in pancreatic ß-cells of the DM control group, while supplementation of AGE resulted in inhibition of apoptotic pathway and regeneration of pancreatic ß-cells. CONCLUSION: The current study suggests that AGE enhance glucose homeostasis by exerting their effects on pancreatic ß-cells, without ameliorating peripheral sensitivity. Moreover, AGEs promote an increase in ß-cell mass by mitigating the apoptosis of pancreatic ß-cells. These findings suggest that AGE could aid in developing a viable alternative therapy for diabetes mellitus (DM).

ABSTRACT

Determining the tumor origin in humans is vital in clinical applications of molecular diagnostics. Metastatic cancer is usually a very aggressive disease with limited diagnostic procedures, despite the fact that many protocols have been evaluated for their effectiveness in prognostication. Research has shown that dysregulation in miRNAs (a class of non-coding, regulatory RNAs) is remarkably involved in oncogenic conditions. This research paper aims to develop a machine learning model that processes an array of miRNAs in 1097 metastatic tissue samples from patients who suffered from various stages of breast cancer. The suggested machine learning model is fed with miRNA quantitative read count data taken from The Cancer Genome Atlas Data Repository. Two main feature-selection techniques have been used, mainly Neighborhood Component Analysis and Minimum Redundancy Maximum Relevance, to identify the most discriminant and relevant miRNAs for their up-regulated and down-regulated states. These miRNAs are then validated as biological identifiers for each of the four cancer stages in breast tumors. Both machine learning algorithms yield performance scores that are significantly higher than the traditional fold-change approach, particularly in earlier stages of cancer, with Neighborhood Component Analysis and Minimum Redundancy Maximum Relevance achieving accuracy scores of up to 0.983 and 0.931, respectively, compared to 0.920 for the FC method. This study underscores the potential of advanced feature-selection methods in enhancing the accuracy of cancer stage identification, paving the way for improved diagnostic and therapeutic strategies in oncology.
