Long-Term Proton Pump Inhibitor Therapy and its Effect on Endocrine Hormones in Selected Patient Population.

Proton pump inhibitors (PPI) are commonly prescribed medications for a variety of gastrointestinal disorders around the globe. Long-term utilization of proton pump inhibitors is linked with different adverse events. Although, short-term therapy has been demonstrated to have little or no impact on endocrine hormones in men, yet its safety with long-term use has poorly been studied. We aimed to evaluate the impacts of long-term utilization of proton pump inhibitors on male reproductive hormones and its clinical outcomes. A cross-sectional study was performed in two out-patients gastroenterology clinics in Khyber Pakhtunkhwa province. Male patients who were using PPIs regularly for≥3 months were enrolled in this study. Among 65 enrolled participants, patients with sexual complaints have significant variations in mean serum levels of prolactin (p<0.001), sex hormone binding globulins (p=0.043), total testosterone (p<0.001) and progesterone (p=0.001) as compared to patients without sexual complaints. Significantly high values of prolactin mean ranks were observed in patient with sexual complaints (p<0.001). There were statistically significant correlations of serum levels of sex hormone binding globulins (p=0.003), total testosterone (p=0.008) and progesterone (p<0.001) with serum prolactin levels. Similarly, statistically significant variation was observed for decreased libido (p=0.001), erectile dysfunction (p=0.001) and decreased semen mass ((p<0.001) between normal and hyperprolactinemic PPI users. Highly significant differences were observed in serum sex hormone binding globulins (p<0.001), total testosterone (p<0.001) and progesterone (p<0.001) values in normal and hyperprolactinemic groups. In conclusion, long-term utilization of PPI may induce endocrine hormone disruption with subsequent sexual complications.

Glucagon-like peptide 1 receptor agonists in end-staged kidney disease and kidney transplantation: A narrative review.

AIMS: Glucagon-like peptide 1 receptor agonists (GLP-1RA) improve glycemic control and promote weight loss in type 2 diabetes (DM2) and obesity. We identified studies describing the metabolic benefits of GLP-1RA in end-staged kidney disease (ESKD) and kidney transplantation. DATA SYNTHESIS: We searched for randomized controlled trials (RCTs) and observational studies that investigated the metabolic benefits of GLP-1RA in ESKD and kidney transplantation. We summarized the effect of GLP-1RA on measures of obesity and glycemic control, examined adverse events, and explored adherence with therapy. In small RCTs of patients with DM2 on dialysis, liraglutide for up to 12 weeks lowered HbA1c by 0.8%, reduced time in hyperglycemia by ∼2%, lowered blood glucose by 2 mmol/L and reduced weight by 1-2 kg, compared with placebo. In prospective studies inclusive of ESKD, 12 months of semaglutide reduced HbA1c by 0.8%, and contributed to weight losses of 8 kg. In retrospective cohort studies in DM2 and kidney transplantation, 12 months of GLP-1RA lowered HbA1c by 2%, and fasting glucose by ∼3 mmol/L compared with non-use, and in some reports, weight losses of up to 4 kg were described. Gastrointestinal (GI) side effects were most commonly reported, with hypoglycemia described with GLP-1RA in hemodialysis, particularly in those using insulin. CONCLUSIONS: GLP-1RA are growing in popularity in those with DM2 and obesity. In small RCTs and observational cohort studies modest glycemic and weight benefits have been described in ESKD and transplantation, but GI side effects may limit adherence. Larger and longer term studies of GLP-1RA remain important.

Potential drug-drug interactions in patients presenting with osteoarthritis to community orthopaedic clinics of Abbottabad, Khyber Pakhtunkhwa: A cross-sectional study.

OBJECTIVES: Osteoarthritis (OA) causes long-term pain and disorders of lower extremities. Paracetamol is the drug of choice; however, NSAIDs, opioids and steroids are frequently employed in the symptomatic relief of OA. The prescribing of multiple analgesics leads to potential drug-drug interactions (pDDIs). The primary objective of this study was to identify the prevalence and predictors of pDDIs in OA. MATERIALS AND METHODS: A total of three hundred and eighty-six patients, either newly diagnosed or with a history of OA, were enrolled for this cross-sectional study. Data regarding patients' demographics, clinical characteristics and prescribed medications were recorded from the prescriptions and examined for the pDDIs using Medscape multidrug interaction checker. RESULTS: Among 386, most patients were females (53.4%). The most prevalent diagnoses were knee OA (39.7%) and unspecified OA (31.3%). Paracetamol and topical NSAIDs were underprescribed whereas an oral NSAID, Diclofenac, was the most frequently used drug in OA. Total of 109 pDDIs were found in 386 prescriptions, of which 63.3% DDIs were categorised as moderate, followed by minor (34.9%) and major (1.8%). CONCLUSIONS: This study finds a prevalence of DDIs and polypharmacy among the OA patients. Collaborative efforts among healthcare providers, pharmacists, and patients themselves are essential to optimize medication regimens and minimize the polypharmacy including the associated risks as well as DDIs.

Prevalence of QTc interval prolongation and its associated risk factors among psychiatric patients: a prospective observational study.

BACKGROUND: QT interval prolongation is a growing concern worldwide, posing psychiatric patients to life-threatening fatal arrhythmias i.e., torsade de pointes. This study aimed to identify the prevalence of QT interval prolongation, its associated risk factors and prescribing patterns of QT prolonging drugs among psychiatric patients. METHOD: A prospective observational study was conducted that included psychiatric patients from a tertiary care hospital and a psychiatry clinic in Peshawar, Khyber Pakhtunkhwa, Pakistan. Electrocardiogram was recorded of those patients who were using psychotropic medications for ≥7 days, aged 18 years or more, and of either gender, male or female. The Fredericia correction formula was used for measuring QTc values (corrected QT). Chi-square test was applied to estimate differences between patients with or without prolonged QTc interval whereas, logistic regression analysis was performed to identify various predictors of QT interval prolongation. RESULTS: Out of 405 patients, the QTc interval was prolonged in 23 (5.7%) patients including 1 (0.2%) patient with highly abnormal prolonged QTc interval (> 500 ms). QT drugs (91.6%), female sex (38.7%) and hypertension (10.6%) were the most common QT prolonging risk factors. Prolonged QTc interval was significantly higher among male patients (p = 0.007). CONCLUSION: In the present study, QT interval prolongation was observed in a considerable number of psychiatric patients. While, the high prevalence of QT prolonging risk factors among these patients warrants the increased risk of fatal arrhythmias. Therefore, risk assessment and electrocardiographic monitoring, and prescription of safer alternatives are highly recommended.

Prevalence of the risk factors for QT prolongation and associated drug-drug interactions in a cohort of medical inpatients.

BACKGROUND/PURPOSE: Medical inpatients are at increased risk of QT interval prolongation due to multiple risk actors and QT prolonging drugs. This study aimed to identify the prevalence of risk factors for QT prolongation; QT prolonging medications; associated drug-drug interactions (QT-DDIs); their predictors; and TdP (torsades de pointes) risks of drugs. METHODS: This cohort study was carried out in medical wards of two tertiary hospitals in Khyber Pakhtunkhwa, Pakistan. The QT-DDIs were identified using Micromedex DrugReax® and AZCERT (Arizona Center for Education and Research on Therapeutics) QT drugs lists. AZCERT QT drugs lists were used to identify TdP risks. Logistic regression analysis was performed to identify predictors of QT-DDIs. RESULTS: Total 400 patients were included in this study. The most frequent QT prolonging risk factors included use of ≥1 QT prolonging drugs (74.5%), female gender (55%) and diabetes mellitus (36.3%). Total 487 QT prolonging drugs were identified. According to AZCERT classification, 33.8% of the interacting drugs were included in list-1 (known risk of TdP), 0.9% in list-2 (possible risk of TdP) and 58.8% in list-3 (conditional risk of TdP). The occurrence of QT-DDIs was significantly associated with ≥10 prescribed medications (p = 0.01), chronic liver disease (p = 0.05), chronic obstructive pulmonary disease (p = 0.03), gastroenteritis (p = 0.02), antimicrobials (p < 0.001), antiemetics (p < 0.001) and antinausea (p < 0.001). CONCLUSION: A substantial number of patients were exposed to risk factors for QT prolongation; and QT prolonging drugs such as proton pump inhibitors, antimicrobials and diuretics which may lead to serious outcomes.

Potential drug-drug interactions in outpatient department of a tertiary care hospital in Pakistan: a cross-sectional study.

BACKGROUND: Potential drug-drug interactions (pDDIs) are one of the preventable drug related problems having the risk of serious adverse events or therapeutic failure. In developing countries like Pakistan, this issue remains poorly addressed. The objective of this study was to explore prevalence of pDDIs in the Outpatient Department (OPD) of a tertiary care hospital in Pakistan. The secondary aim was to describe the levels of reported pDDIs and develop a list of widespread clinically relevant interactions. METHODS: Prescriptions of 2400 OPD patients were analyzed for pDDIs through Micromedex Drug-Reax®. Prevalence, severity- and documentation-levels and widespread clinically relevant interactions were reported. RESULTS: Of total 2400 prescriptions, pDDIs were present in 22.3%. Whereas, moderate- and major-pDDIs were found in 377 (15.7%) and 225 (9.4%), respectively. PDDIs were more prevalent in Medicine (9.2%) and Cardiology (2.6%) as compared with other OPD specialties. Total 942 pDDIs were identified, of which, the majority were either moderate- (61.9%) or major-pDDIs (32.1%). Some of the most common interactions were ibuprofen + levofloxacin (n = 50), ciprofloxacin + diclofenac (32), aspirin + atenolol (24), and diclofenac + levofloxacin (19). The potential adverse outcomes of widespread interactions were seizures, bleeding, QT-interval prolongation, arrhythmias, tendon rupture, hypoglycemia/hyperglycemia, serotonin syndrome, drug toxicity, and decreased therapeutic response. CONCLUSIONS: OPD patients were at risk to pDDIs, particularly to major- and moderate-pDDIs. Screening of prescriptions for pDDIs and monitoring of pharmacotherapy in terms of response and associated adverse drug events will contribute to patient safety.

QT interval prolongation in hospitalized patients on cardiology wards: a prospective observational study.

PURPOSE: Prolonged QT interval may lead to a lethal form of arrhythmia, torsades de pointes (TdP), which is associated with cardiovascular mortality. Therefore, we aimed to identify prevalence of QT interval prolongation, compare clinical characteristics of patients with normal and prolonged QT interval, and identify predictors of QT interval prolongation. METHODS: A prospective observational study was conducted in cardiology wards of two teaching hospitals in Pakistan. Bazett's correction formula was used for the calculation of QTc interval. Prevalence of QT prolongation and pro-QTc scores were calculated. Comparative analysis was performed with respect to various clinical characteristics by applying t test and chi-square test. Odds ratios were calculated using regression analysis. RESULTS: Among 417 patients, 44.6% were found having prolonged QT interval, of which, 17.3% presented with an abnormally high QTc interval (> 500 ms). Significant difference was recorded between the groups (normal vs. prolonged) with respect to age, all prescribed medications, QT drugs, number of risk factors, QT-DDIs (QT-prolonging drug-drug interactions), gender, and diuretics use. Multivariate logistic regression analysis showed significant results for various predictors such as male gender (p = 0.03), various age categories 41-50 years (p = 0.04), 51-60 years (p = 0.01), and > 60 years (p < 0.001), and diuretics (p = 0.008). CONCLUSION: A substantial number of patients in cardiology wards presented with QT prolongation. Proper considerations are needed in order to minimize the associated risk particularly in patients with abnormally high QT prolongation, old age, polypharmacy, one or more QT-prolonging drugs, and high pro-QTc scores.

Surface plasmon-enhanced quantum dot light-emitting diodes by incorporating gold nanoparticles.

Surface plasmon-enhanced electroluminescence (EL) has been demonstrated by incorporating gold (Au) nanoparticles (NPs) in quantum dot light-emitting diode (QLED). Time-resolved photoluminescence (TRPL) spectroscopy reveals that the EL enhancement is ascribed to the near-field enhancement through an effective coupling between excitons of the quantum dot emitters and localized surface plasmons around Au NPs. It is found that the size of Au NPs and the distance between the Au NPs and the emissive layer have significant effects on the performance of QLED. The enhancement can be maximized as the SP resonance wavelength of Au NPs matches well with the PL emission wavelength of the QD film and the distance between Au NPs and the emissive layer maintains 15 nm. The photoluminance (PL) and EL intensity can be enhanced by 4.4 and 1.7 folds with the incorporation of Au NPs. The maximum current efficiency of 4.56 cd/A can be achieved for the resulting QLEDs by incorprating Au NPs with an enhancement factor of 2.0. In addition, the enhancement ratio of 2.2 can be achieved for the lifetime of resulting QLED.

Identification and Fibrosis Staging of Hepatitis C Patients Using the Electronic Medical Record System.

BACKGROUND AND AIMS: The aim of this study was to noninvasively assess the severity of chronic hepatitis C virus (HCV) in large patient populations. It would be helpful if fibrosis scores could be calculated solely on the basis of data contained in the patients' electronic medical records (EMR). We performed a pilot study to identify all HCV-infected patients in a large health care system, and predict their fibrosis stage on the basis of demographic and laboratory data using common data from their EMR. MATERIALS AND METHODS: HCV-infected patients were identified using the EMR. The liver biopsies of 191 HCV patients were graded using the Ishak and Metavir scoring systems. Demographic and laboratory data were extracted from the EMR and used to calculate the aminotransferase to platelet ratio index, Fib-4, Fibrosis Index, Forns, Göteborg University Cirrhosis Index, Lok Index, and Vira-HepC. RESULTS: In total, 869 HCV-infected patients were identified from a population of over 1 million. In the subgroup of patients with liver biopsies, all 7 algorithms were significantly correlated with the fibrosis stage. The degree of correlation was moderate, with correlation coefficients ranging from 0.22 to 0.60. For the detection of advanced fibrosis (Metavir 3 or 4), the areas under the receiver operating characteristic curve ranged from 0.71 to 0.84, with no significant differences between the individual scores. Sensitivities, specificities, and positive and negative predictive values were within the previously reported range. All scores tended to perform better for higher fibrosis stages. CONCLUSIONS: Our study demonstrates that HCV-infected patients can be identified and their fibrosis staged using commonly available EMR-based algorithms.

Continuous graphene and carbon nanotube based high flexible and transparent pressure sensor arrays.

The transparent pressure sensing arrays durable to severe deformation are fabricated by covering the continuous graphene sheets on the tip of thermal plastic polyurethane (TPU) pyramids, while most of the TPU surface is covered by a layer of densely entangled single wall carbon nanotubes. The transparency of the conducting layer exceeds 91%. The capacitance variations between TPU surface and flat electrode under compressive deformation show high sensitivity and a broad dynamic range from hundreds Pa to MPa. The measured capacitance variations show high load sensitivity and stability under repeated deformation cycles. Finite element numerical simulations present that the contact area change under deformation increases the capacitance variation. The high stability of the capacitance response to fluctuated loads demonstrates that graphene layer on the surface of TPU pyramids maintains the continuity of electric contact under a large deformation ratio and high repeating cycles. 16 × 16 arrays are connected to a circuit and a typical load distribution is regenerated by mapping the local capacitance variations on the arrays with sub-minimeter spatial resolution.

The study results reveal that both AI and social media have a positive impact on academic performance and mental well-being among university students. Furthermore, smart learning serves as a positive mediating variable, amplifying the beneficial effects of AI and social media on both academic performance and mental well-being. These revelations contribute to the discourse on technology-enhanced education, showing that embracing AI and social media can have a positive impact on student performance and well-being.

Effects of long-term proton pump inhibitor use on sexual hormones and sexual and reproductive health in female patients.

PURPOSE: Proton pump inhibitors (PPIs) are widely used to treat a range of gastrointestinal diseases around the world. Long-term use of PPIs has been associated to a variety of undesirable effects. Although short-term therapy has been shown to have little or no effect on endocrine hormone in women, however, its long-term safety has received little attention. We aimed at evaluating long-term use of PPIs and its effects on female reproductive hormones as well as related clinical consequences. METHODS: A cross-sectional study was conducted in two outpatient gastroenterology clinics in the province of Khyber Pakhtunkhwa. This study included female patients who had been using PPIs on a regular basis for 3 months or more. RESULTS: In total of 101 participants, patients with sexual complaints have significantly altered levels of prolactin (p = 0.05), estrogen (p < 0.001) and progesterone (p = 0.001) than patient without sexual complaints. The frequency of amenorrhea (p < 0.001), cyclic disturbances (p < 0.001), breast augmentation (p = 0.001) and painful breast (p = 0.004) were statistically significant in patients with raised serum prolactin values. Serum values of Sex hormone binding globulin SHBG (p < 0.001), estradiol (p = 0.002) and total testosterone (p < 0.001) were significantly altered between normal prolactin and hyperprolactinemic patients. CONCLUSION: These findings suggest that long-term PPI use may cause endocrine hormone disturbances leading to sexual difficulties in women.

Questionnaire-Based Study of 392 Women in Abbottabad, Pakistan, to Evaluate the Types of Cosmetic Products Purchased Between December 2018 and March 2019 and Their Associated Adverse Events.

BACKGROUND Cosmetics are applied topically to enhance appearance and are commonly used by women of all ages. Cosmetics contain many chemical agents, but the incidence of adverse reactions is low, possibly due to underreporting. This questionnaire-based study included 392 women to evaluate information on the types of cosmetics purchased between December 2018 and March 2019, their use by the women surveyed, and their associated adverse events. MATERIAL AND METHODS A cross-sectional study was conducted among 392 women in Abbottabad, Pakistan, using a pre-structured and validated questionnaire to evaluate information on the types of cosmetics, their use, and their associated adverse events. Part 1 of the study collected information about demographics. Part 2 contained a total of 11 items, and collected the frequency of use of cosmetic on skin and hair care products. Part 3 consisted of 4 items and collected information about problems encountered due to the use of cosmetics. RESULTS In the winter season, 47.7% (n=187) of women preferred chemical-based cosmetic products, while 30.9% (n=121) preferred Ayurvedic products. Among commonly used cosmetic products, 26.9% (n=106) of women used foundations. The most frequently used skin care product was face wash 39.5% (n=155). The most prevalent adverse events related to cosmetics were pimples (19.9%, n=78), redness (17.6%, n=69), and eye discomfort (15.8%, n=62). Furthermore, 51.3% (n=201) strongly agreed that cosmetics aid in getting a whiter complexion. CONCLUSIONS The survey concluded that most women preferred cosmetics with a chemical base, which are associated with rashes, redness, and acne. It is important to encourage cosmetovigilance and awareness campaigns among cosmetic product sellers and users.

Consumption of proton pump inhibitors in outpatients of Gastroenterology Clinics in Khyber Pakhtunkhwa: evidence of inexpedient use.

Introduction: Proton pump inhibitors (PPIs) are effective drugs used for multiple gastrointestinal complications. They are commonly used in both hospitalised and outpatients. However, little is known about its utilisation pattern in ambulatory patients. Aim: To evaluate the inexpedient continuous use of PPIs in patients with respect to treatment duration. Material and methods: A cross-sectional observational study was conducted from January 2018 to November 2019 in Khyber Pakhtunkhwa, Pakistan. Regular proton pump inhibitor users were identified through patient histories. Results: During the study period, 171 patients were included using a non-probability consecutive sampling technique, who were using regular proton pump inhibitors for a longer duration, i.e. from 3 months to 15 years. The highest proportion (42.8%) were using PPI regularly from 3 months to 1 year followed by 22.9% for 1-2 years, 12.0% for 2-3 years, 7.8% for 3-4 years, 4.2% for 4-5 years, and 10.24% for > 5 years. Omeprazole and esomeprazole were the most commonly used drugs, with 71.1% and 23.5% prevalence, respectively. A total of 33.73% of patients had continued PPI use on their own after initially being prescribed by the physician. Conclusions: It can be deduced that PPIs are used in outpatients beyond standard treatment guidelines. The inexpedient continuous use of proton pump inhibitors is of concern due to the risk of developing adverse effects. Therefore, patient counselling and periodic monitoring must be carried out to prevent the irrational use of PPIs.

From industrialization to dehumanization: understanding the deriving forces of environment and implications for sustainable development.

Environment has detrimental effects on economic activity and human survival. Climate change is increasingly conducive to natural disasters, epidemics, social conflicts, food security, financial shocks, economic hardships, and life subsistence. In pursuit of this issue, this study empirically investigates the effects in outcome variable CO2 provoked by independent variables governance, technological innovation, renewable energy, economic growth, and economic policy uncertainty in APEC economies. The APEC region accounts for 60% of global emissions, 62% of world GDP, 48% of global trade and contribute 8.7% renewable energy annually. A dynamic panel PMG-ARDL model is applied under the assumption of maximum likelihood estimation with DH causality and CS-ARDL for the period of 1996-2020. Our empirical results confirm that governance, technology innovation, and transitional energy have significant and positive effect to mitigate CO2 emissions. The region needs to design policy mechanisms supportive to promote institutional quality, enhances transparency, ensure political stability and rule of law. It develops the infrastructure that ensures the adaptation of technology innovations, promotes green growth, improves energy efficiency, and implements carbon pricing mechanism. Economic policy uncertainty has insignificant and positive effects on environmental degradation. The findings show that governance, technological development, and transitional energy have an essential role to mitigate CO2 emissions and achieve sustainable development. Moreover, this study will be helpful in understanding the implications of SDGs and achieving specific targets such as (SDG-7: Clean energy sources) and (SDG-8: Sustainable development goal) based on the largest set of emitters APEC.

Multiband antenna design with enhanced radiations using characteristic mode analysis.

In this research, a multiband patch antenna design based on the superposition of multiple modes at the same resonant frequency is presented. The concept of the contribution of lower order modes (LOMs) with the higher order dominant modes (HODMs) is investigated using characteristic mode analysis (CMA). In order to provide similar broadside radiations in three bands, the radiating capability of the LOMs is enhanced in the resonant frequencies of HODMs. These HODMs when excited alone provide null in the broadside radiations of the antenna. Using a single feed, enhancement in the broadside radiations of the antenna is achieved with the superposition of multiple modes at the same resonant frequency. Based on the proposed concept two antennas have been designed and fabricated. The antenna provides stable and enhanced radiations. simulated and measured results are in good agreement. These antennas find application in many applications including communication systems, base station antennas, 5G communications, satellite communication etc.

From COVID to conflict: Understanding the deriving forces of environment and implications for natural resources.

In the contemporary world, the importance of natural resources is increasing day by day especially due to extraordinary circumstances, i.e., COVID-19 and global conflicts. The abundance of natural resource is considered competitive advantage and crucial for sustainable development. However, the role of natural resources can be questionable especially if its impact on the economy is negative. Sustainable use of natural resources is currently the biggest challenge for governance. Following these footprints, the study aims to revisit a novel perspective of natural resources in the context of global conflicts using data from Asian economies for the period of 1996-2020. In this pursuit, this study investigates how governance balances macroeconomic variables with sustainable development to account for effective climate change adaptation, mitigation efforts and integral to control conflicts. The second-generation test of CIPS and CADF are used to deal with cross-sectional dependence issues and Westerlund cointegration to estimate long-run relationships. Furthermore, the long-run coefficients are estimated by the PMG estimator using dynamic panel ARDL approach. The findings confirm that surpassing the threshold level of governance is essential to promote environmental quality and preservation of natural resources. The region needs to promote steward policy for resources. This can take the form of nationalizing resource assets, increasing taxes and royalties on resource extraction to ensure sustainable development. The handlers need to design polices supportive to renewable energy consumption, endorse IT based industry solution, encourage high-tech inward FDI, promote green financing and support sustainable development.

Investigation of CeO2 nanoparticles on the performance enhancement of InsulatingOils.

Integrating nanotechnology in dielectric fluid significantly inhibits losses and boosts overall dielectric fluid performance. There has been research done on the effects of introducing various nanoparticles, such as titania, alumina, silica nanodiamonds, etc. In this paper, a novel nanoparticle, Ceria (CeO2), has been used, and its properties were examined using the FTIR (Fourier Transform Infrared) spectrum, the XRD (X-ray Diffraction) spectrum, the SEM (Scanning Electron Microscopy), and the TEM (Transmission Electron Microscopy). This paper illustrates an efficient dielectric fluid prepared by the successful dispersion of Cerium Oxide (CeO2) nanoparticles in various concentrations into four commercial oils, namely mineral oil, rapeseed oil, synthetic ester oil, and soybean oil, to enhance and improve their dielectric characteristics. The performance investigation emphasises breakdown strength enhancement and other dielectric properties of the colloidal solution comprising different nanoparticle (NP) concentrations. Various commercial oils are used as a base in nano-oil to diversify their applicability as dielectric fluids by measuring the correlation in dielectric parameters and statistically assessing their applicability with normal and Weibull distributions. The obtained experimental data sets were analyzed using the Statistics and Machine Learning Toolbox in MATLAB. The aging measurement has been done only on mineral oil, and results were matched using a predictive model of statistics and the Machine Learning Toolbox in MATLAB. Well-dispersed CeO2 NPs in the insulating oils lead to a significant increase in AC breakdown strength. The effect of ageing on the dielectric properties of nano oils yields better results than conventionally aged oil. It has been observed that the breakdown voltage is enhanced by up to 30% for mineral oil at an optimal concentration of 0.01 g/L, 9% for synthetic ester oil at 0.03 g/L, 18% for rapeseed oil at 0.02 g/L, and 19% for soybean oil at 0.03 g/L nanoparticle concentration. Following the dispersion of CeO2 nanoparticles, the dielectric constant of all insulating oils has also significantly improved. The overall experimental results are promising and show the potential of the CeO2 NPs-based nano oil as an efficient and highly performing dielectric oil for different power applications.
