Impact of Patient Education Formats on Treatment Adherence and Denture Hygiene in Edentulous Patients: A Comparative Study.

BACKGROUND Effective communication and patient education are important in geriatric dental care. Memory decline complicates patient adherence. This study aimed to compare verbal, audio, and video patient education material (PEM) and adherence to dental prosthetic management in edentulous patients. MATERIAL AND METHODS 90 completely/partially edentulous patients (aged 40 to 70 years), were divided (simple random) into three groups (Gp) of 30 each . A total of 68 instructions were organized into 9 learning categories. For GpVi, a 20 minute video was shot using a Sony camera (PD170), with two actors depicting related PEM information. Patients were recalled after 1 day and 7days, to recall the PEM instructions. A Denture plaque Index (DPI) determined the efficiency of the instructions at both time intervals. Frequencies, means and standard deviations were derived for each group and then compared using Chi square, paired and unpaired t test and a Neuman-Keul post hoc pairwise test. All significant differences were kept at probability t value of ≤0.05. RESULTS PEM instructions related to patient individuality, proper tongue position and miscellaneous showed poor patient recall. At 1 day interval, audio was found to have better recall than video and verbal in 5 PEM instruction categories. At 7 day interval, video showed better recall than other two groups (P≤0.05). Despite improvements in patients recall, DPI revealed better denture hygiene maintenance in patients receiving instructions through video format (P≤0.05). CONCLUSIONS For all categories, no single media was considered to be sufficient, audio produced early better recall while video influenced long term recall and better denture hygiene maintenance.

The Global Prevalence of Metabolic Syndrome in Connection with Sleep Duration: A Systematic Review and Meta-Analysis.

The duration and quality of sleep are believed to significantly influence the onset of metabolic syndrome (MetS), but existing data lack consistency. The meta-analysis aims to evaluate the prevalence of the MetS in association with sleep duration. We conducted a systematic review according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses 2020 guidelines. A comprehensive search of PubMed, Google Scholar, and Research Gate databases was performed to identify cohort and cross-sectional studies published in English between 2013 and 2023. We included studies that examined the association between sleep duration/quality and MetS, and two independent reviewers assessed study quality and bias using the Newcastle-Ottawa scale. The systematic review included 11 studies with a total of 343,669 participants, including 4 cohort studies and 7 cross-sectional studies. Sample sizes varied widely, ranging from 293 to 162,121 individuals. The studies had different follow-up periods, participant ages ranging from 10 to 80 years, and predominantly male populations. The prevalence of MetS was higher in average sleepers [52%, 95% confidence interval (CI): 40%-64%] compared with short sleepers (13%, 95% CI: 8%-18%) and long sleepers (15%, 95% CI: 9%-24%). Globally, North American countries exhibit the highest prevalence of MetS across short- (25.3%, 95% CI: 4.2%-72.4%) and long-sleeper (22.4%, 95% CI: 2.8%-74.1%) categories, whereas Asian countries experience the highest prevalence among the average sleeper category (58.7%, 95% CI: 44.1%-71.9%). Our meta-analysis indicates an elevated prevalence of MetS in average sleepers. Future research endeavors address delve into the underlying mechanisms and incorporate objective measures to understand the multifaceted connection between sleep patterns and MetS, guiding more effective preventive and management strategies.

Comparing color match by conventional trial and error method with maxillofacial spectrophotometer method for the skin of Indian participants: A subjective and objective assessment.

STATEMENT OF PROBLEM: The comparative accuracy of different color-matching methods for maxillofacial prostheses is lacking. PURPOSE: This clinical study aimed to compare prosthesis color matching using the conventional trial and error method with that using the maxillofacial spectrophotometer method. MATERIAL AND METHODS: Fifty-four Indian participants were enrolled based on skin color and divided into Light, Medium, and Dark groups (n=18). Silicone specimens of different thicknesses were fabricated using both the conventional trial and error and maxillofacial spectrophotometer coloration methods for all participants. The color match of the specimens with natural skin was assessed subjectively and objectively using expert consensus and fiber optic spectroscopy with the CIELab color difference formula, respectively. Statistical analyzes included the Shapiro-Wilk and independent sample t tests (α=.05). RESULTS: The mean ΔL* (white-black axis) value for the Skin-Conventional color match difference was significantly lower and positive compared with the Skin-Spectrophotometer match (P=.090) for the sample. The mean Δb* (yellow-blue axis) value for the Skin-Conventional color difference was significantly positive compared with the Skin-Spectrophotometer match (P=.020). The mean ΔE* (color difference) for the Skin-Conventional color match was significantly lower than the Skin-Spectrophotometer value (P=.034). Expert opinion as assessed with a visual analog scale found color matching using the conventional method (7.12) to be significantly better than with the spectrophotometer (6.30). A qualitative analysis of expert opinion revealed that conventional color matching should have been less red (34.3%) and that spectrophotometer matching should have been less yellow (30.1%). CONCLUSIONS: Across different thicknesses of silicone and Indian skin shades, color matching was significantly better for the conventional versus the maxillofacial spectrophotometer method, both objectively and subjectively. The spectrophotometer match was significantly yellower and lighter than natural skin.

Evaluation of Retentive Strength of 50 Endodontically-Treated Single-Rooted Mandibular Second Premolars Restored with Cast Post Cores Using 5 Common Luting (Cement) Agents.

BACKGROUND A luting agent is a dental cement used to secure a dental restoration. This study aimed to evaluate retentive strength of 50 endodontically-treated single-rooted mandibular second premolars (extracted) restored using 5 common luting (cement) agents. MATERIAL AND METHODS Fifty single-rooted mandibular second premolars with adequate root length and uniform size/shape were decoronated. After completing endodontic biomechanical preparation and obturation, root canals of all specimens were prepared to receive a cast post core. Depending upon cementation type, CPC specimens were divided in 5 groups (10 each) (Gp): Zinc phosphate (Gp ZP), polycarboxylate (Gp PC), glass ionomer (Gp GI), resin-modified glass ionomer (Gp RGI), and resin cement (Gp RC). Retentive strength was determined using the adhesive failure pull-out test. Mean/standard deviations were calculated for tensile forces (in kilograms) and differences were determined using analysis of variance (ANOVA). Multiple comparison was performed using the t test. A P value of ≤0.05 indicated a statistically significant difference. RESULTS The order of mean tensile strength from higher to lower was Gp RC (21.46) >Gp RGI (18.17) >Gp GI (16.07) >Gp ZP (15.33) >Gp PC (13.63). Differences in retentive strengths between the cements were significant (P≤0.05). Multiple-group comparisons showed that except for Gp ZP and Gp GI, all groups differed significantly from each other. CONCLUSIONS All investigated cements provided optimal retentive strengths, with wide differences between them. Resin cements should be used when CPC removal is not anticipated, while polycarboxylate or zinc phosphate should be used if CPC removal is anticipated.

Role and application of CRISPR-Cas9 in the management of Alzheimer's disease.

Alzheimer's disease (AD) is a serious health issue that has a significant social and economic impact worldwide. One of the key aetiological signs of the disease is a gradual reduction in cognitive function and irreversible neuronal death. According to a 2019 global report, more than 5.8 million people in the United States (USA) alone have received an AD diagnosis, with 45% of those people falling into the 75-84 years age range. According to the predictions, there will be 15 million affected people in the USA by 2050 due to the disease's steadily rising patient population. Cognitive function and memory formation steadily decline as a result of an irreversible neuron loss in AD, a chronic neurodegenerative illness. Amyloid-beta and phosphorylated Tau are produced and accumulate in large amounts, and glial cells are overactive. Additionally, weakened neurotrophin signalling and decreased synapse function are crucial aspects of AD. Memory loss, apathy, depression, and irritability are among the primary symptoms. The aetiology, pathophysiology, and causes of both cognitive decline and synaptic dysfunction are poorly understood despite extensive investigation. CRISPR/Cas9 is a promising gene-editing technique since it can fix certain gene sequences and has a lot of potential for treating AD and other human disorders. Regardless of hereditary considerations, an altered Aß metabolism is frequently seen in familial and sporadic AD. Therefore, since mutations in the PSEN-1, PSEN-2 and APP genes are a contributing factor to familial AD, CRISPR/Cas9 technology could address excessive Aß production or mutations in these genes. Overall, the potential of CRISPR-Cas9 technology outweighs it as currently the greatest gene-editing tool available for researching neurodegenerative diseases like AD.

This narrative review navigates the dynamic landscape of epilepsy classification, offering insights into recent developments, challenges, and the promising horizon. Historically, epilepsy classification relied heavily on clinical observations, categorizing seizures based on their phenomenology and presumed etiology. However, the field has profoundly shifted from a symptom-based approach to a more refined, multidimensional system. One pivotal aspect of this evolution is the integration of neuroimaging techniques, particularly magnetic resonance imaging (MRI) and functional imaging modalities. These tools have unveiled the intricate neural networks implicated in epilepsy, facilitating the identification of distinct brain abnormalities and the categorization of epilepsy subtypes based on structural and functional findings. Furthermore, the role of genetics has become increasingly prominent in epilepsy classification. Genetic discoveries have not only unraveled the molecular underpinnings of various epileptic syndromes but have also provided valuable diagnostic and prognostic insights. This narrative review delves into the expanding realm of genetic testing and its impact on tailoring treatment strategies to individual patients. As the classification landscape evolves, there are accompanying challenges. The narrative review underscores the transformative potential of artificial intelligence and machine learning in epilepsy classification. These technologies hold promise in automating the analysis of complex neuroimaging and genetic data, offering enhanced accuracy and efficiency in epilepsy diagnosis and classification. In conclusion, navigating the shifting landscape of epilepsy classification is a journey marked by progress, complexity, and the prospect of improved patient care. We are charting a course toward more precise diagnoses and tailored treatments by embracing advanced neuroimaging, genetics, and innovative technologies. As the field continues to evolve, collaborative efforts and a holistic understanding of epilepsy's diverse manifestations will be instrumental in harnessing the full potential of this dynamic landscape.

Experimental and Computational Insights into the Overall Water Splitting Reaction by the Fe-Co-Ni-P Electrocatalyst.

Nonprecious transition-metal phosphides (TMPs) are versatile materials with tunable electronic and structural properties that could be promising as catalysts for energy conversion applications. Despite the facts, TMPs are not explored thoroughly to understand the chemistry behind their rich catalytic properties for the water splitting reaction. Herein, spiky ball-shaped monodispersed TMP nanoparticles composed of Fe, Co, and Ni are developed and used as efficient electrocatalysts for hydrogen and oxygen evolution reaction (HER, OER), and overall water splitting in alkaline medium; and their surface chemistry was explored to understand the reaction mechanism. The optimized Fe0.5CoNi0.5P catalyst shows attractive activities of HER and OER with low overpotentials and Tafel slopes, and with high mass activities, turnover frequencies, and exchange current densities. When applied to overall water splitting, the electrolyzer Fe0.5CoNi0.5P||Fe0.5CoNi0.5P cell can reach a 10 mA cm-2 current density at cell voltages of only 1.52 and 1.56 V in 1.0 M and 30 wt % KOH, respectively, much lower than those of commercial IrO2||Pt/C. The optimized electrolyzer with sizable numbers of chemically active sites exhibits superior durability up to 70 h and 5000 cycles in 1.0 M KOH and can attain a current density as high as 1000 mA cm-2, showing a class of efficient bifunctional electrocatalysis. Experimental and density functional theory-based mechanistic analyses reveal that surface reconstruction takes place in the presence of KOH to form the TMP precatalyst, which results in high coverage of oxygen active species for the OER with a low apparent activation energy (Ea) for conversion of *OOH to O2. These also evidenced the thermoneutral adsorption of H* for the efficient HER half-reaction.

Prosthodontic Rehabilitation's Role in Alleviating Anxiety and Depression in Mucormycosis-Induced Maxillectomy Patients Post-COVID-19.

BACKGROUND The aim of this study was to assess the influence of maxillofacial prosthodontic rehabilitation on anxiety/depression severity in patients with rhino-orbital cerebral mucormycosis (ROCM) after maxillectomy. MATERIAL AND METHODS Sixty post-mucormycotic patients treated with maxillectomy (33 males, 27 females) were divided into 5 groups based on maxillectomy types (unilateral/bilateral, subtotal/total) and treatment given (psychotherapy/obturator/implant/orbital/ocular prosthesis). Anxiety and depression symptoms were assessed using appearance anxiety inventory (AAI) and patient health questionnaire (PHQ9). Data were collected at 4 time intervals [T0 (before prosthesis), T1 (2 weeks after prosthesis), T2 (6 months) and T3 (1 year). Frequency distribution and mean values were determined for individual group/subgroups/total cohort. Differences between groups were determined using one-way ANOVA (single-factor/Friedman's) followed by post hoc correction (Bonferroni) and t test for unequal variance with probability P value being statistically significant at <0.05. RESULTS The mean scores for appearance anxiety were 29.13±4.72 (diagnostic for existing body dysmorphic disorder) at T0, which decreased to 16.88±3.02 at T3 for the total cohort. The differences for the gender-based cohort, its various groups, and respective subgroups were significant (P<0.05) at various time intervals. The mean scores in the total cohort for depression symptom severity were 16.81±4.89 (moderately severe) at T0, which increased to 18.5±4.94 at T1, followed by reduction at T2 (12.0±4.43; moderate) and T3 (7.38±3.37; mild). Gender differences for both variables were found to be statistically significant (P<0.05). CONCLUSIONS Comprehensive rehabilitation that included a diagnosis of psychological symptoms followed by psychotherapeutic/pharmacotherapeutic/prosthodontic intervention reduced the anxiety/depression symptom levels to normal at 1 year.

Seizing the Connection: Exploring the Interplay Between Epilepsy and Glycemic Control in Diabetes Management.

Epilepsy, a neurological disorder characterized by recurrent seizures, and diabetes, a metabolic disorder characterized by impaired regulation of glucose levels, are two distinct conditions that may appear unrelated at first glance. Nevertheless, recent scholarly investigations have revealed these entities' intricate and ever-evolving interplay. This review initially delves into the intricate interplay between epilepsy and its potential ramifications on glycemic control. Seizures, particularly those accompanied by convulsive manifestations, have the potential to induce acute perturbations in blood glucose levels via diverse mechanisms, encompassing the liberation of stress hormones, the emergence of insulin resistance, and the dysregulation of the autonomic nervous system. Comprehending these intricate mechanisms is paramount in customizing productive strategies for managing diabetes in individuals with epilepsy. On the contrary, it is worth noting that diabetes can substantially impact the trajectory and control of epilepsy. The correlation between hyperglycemia and an elevated susceptibility to seizures, as well as the potential for exacerbating the intensity of epilepsy, has been established. This narrative review offers a concise exposition of the intricate interplay between epilepsy and glycemic control within diabetes management. The objective of exploring reciprocal influences, underlying mechanisms, and common risk factors is to augment the clinical comprehension of this intricate interconnection. In essence, this acquired knowledge possesses the potential to serve as a guiding compass for healthcare professionals, enabling them to craft bespoke therapeutic approaches that enhance the holistic welfare of individuals grappling with the coexistence of epilepsy and diabetes.

Choices and Challenges With Treatment of Myasthenia Gravis in Pregnancy: A Systematic Review.

Myasthenia gravis (MG) is an autoimmune disease affecting young women in their second and third decades, coinciding with their reproductive years. We aim to explore the choices and challenges in the treatment of MG in pregnancy. Cochrane, PubMed, Google Scholar, and Embase were the four databases systematically searched for studies with patients reporting pregnancy outcomes for women with MG during pregnancy using the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) technique. Quality assessment was done using the Joanna Briggs Institute critical tool (JBI, Adelaide, Australia) for methodological quality. From 2000 to 2023, 40 studies from database search results were considered. There is a substantial risk of complications with MG, especially if it appears during pregnancy. In particular, widespread weakness is a cause of severe, life-threatening disorders, but several treatment options are available.

Exploring the Effectiveness and Safety of Azilsartan-Medoxomil/Chlorthalidone Versus Olmesartan-Medoxomil/Hydrochlorothiazide in Hypertensive Patients: A Meta-Analysis.

This study aims to assess the effectiveness and safety of azilsartan-medoxomil/chlorthalidone (AZI-M/CT) compared to olmesartan-medoxomil/hydrochlorothiazide (OLM/HCTZ) in patients with hypertension. Systematic searches were conducted on PubMed, Google Scholar, and ClinicalTrials.gov, starting from their establishment until March 15, 2023. The purpose of these searches was to locate original reports that compare the effectiveness of AZI-M/CT and OLM/HCTZ in treating hypertension. Data on various characteristics at the beginning and end of the studies were gathered. The analyses were carried out using Review Manager 5.4.1 (The Nordic Cochrane Center, The Cochrane Collaboration, 2014, Odense, Denmark) and STATA 16.0 software (Stata Corp. LP, College Station, TX, USA). Risk ratios (RRs) and weighted mean differences (WMDs) with 95% confidence intervals (CIs) were calculated as part of the study. A total of 3,146 individuals from four separate investigations were included in the study, with 1,931 individuals receiving AZI-M/CT and 1,215 individuals receiving OLM/HCTZ. The combined analysis revealed that the average diastolic blood pressure (DBP) was significantly lower in the AZI-M/CT group compared to the OLM/HCTZ group (WMD -2.64 [-2.78, -2.51]; P = 0.00001; I2 = 1%). However, there were no significant differences in mean systolic blood pressure (SBP; WMD -2.95 [-6.64, 0.73]; P = 0). Furthermore, the AZI-M/CT group had a notably higher incidence of major adverse events (RR 1.58 [1.20, 2.08]; P = 0.001; I2 = 11%) and any treatment-emergent adverse events (RR 1.11 [1.03, 1.20]; P = 0.007; I2 = 51%). However, there was no significant difference in the mortality risk between the two groups (RR 0.74 [0.14, 3.91]; P = 0.72; I2 = 0%). Based on the results of our meta-analysis, AZI-M/CT is more effective than OLM/HCTZ at reducing blood pressure in elderly hypertensive patients. However, because of the small sample size, favorable results must be carefully reevaluated, and more studies are needed.

Influence of Prosthodontic Rehabilitation Using Zygomatic Implants in Covid 19 Related Mucormycosis (Rhino-Orbital-Cerebral) Maxillectomy Patients Upon Post-Operative Stress, Anxiety and Functional Impairment: A Prospective Cohort Study.

Purpose: To determine the influence of prosthodontic rehabilitation using zygomatic implants in partial maxillectomy upon post-operative stress, anxiety and functional impairment, due to covid 19 associated rhino-orbital-cerebral mucormycosis (ROCM). Patients and Methods: Twenty maxillectomy patients fulfilling study criterion, received zygomatic implants (ZI) (quad zygoma) (ZDI Simpladent, Switzerland) retained/supported complete maxillary denture. Assessment of stress, anxiety, masticatory performance and speech were determined using diurnal salivary cortisol level, Appearance Anxiety Inventory, multiple sieve technique and auditory perception analysis, respectively. Data were recorded at 6 different stages of rehabilitation (after maxillectomy, implant placement, and after prosthesis delivery (1 week, 1 month, 6 months and 1 year)). Demographic data were expressed as frequency distribution, while mean values were used to find differences between various rehabilitation stages using Friedman and chi-square test with statistical significance value at p < 0.05. Results: Average daily salivary cortisol levels declined from post maxillectomy (22.80 ± 0.902) to 1 year after prosthesis wearing (8.65 ± 0.985), indicating stress reduction after ZI rehabilitation. Mean scores for appearance anxiety reduced from pre-prosthetic rehabilitation (27.350 ± 3.030) to 1 year (8.950 ± 0.887) following prosthesis wearing. Functional parameters for mastication and speech also improved significantly during the course of rehabilitation. All differences between pre-prosthetic to 1-year stage after prosthesis wearing were found to be statistically significant at p < 0.05. Conclusion: Post ROCM maxillectomy cases after prosthetic rehabilitation using zygomatic implants showed significant improvement in the psychological (stress and anxiety) as well as function (mastication and speech) characteristics. Rehabilitation post ROCM maxillectomy with the present approach of fixed prosthesis using zygomatic implants mitigates deficient mastication and speech. It also impacts positively on patient psychology by decreasing stress and anxiety.

A Clinical Study of 50 Partially Edentulous Patients with Fixed Partial Denture Restorations to Compare Clinical Parameters and Changes in Gingival Sulcus Width After Displacement with 2 Different Gingival Retraction Cord Materials (Cotton and Polymer).

BACKGROUND The present study aimed to compare the clinical performance and gingival sulcus width changes in partially edentulous patients using cotton and polymer gingival retraction cords. MATERIAL AND METHODS Fifty partially edentulous patients were divided into 2 groups (Gp C and Gp P) and were subjected to single crown/fixed partial denture treatment. Clinical parameters, including plaque index scores, placement time, and hemorrhage control scores, were assessed. Gingival sulcus width changes before and after retraction were evaluated using individual type 4 dental stone dies observed under an optical microscope. Statistical analysis was performed using dependent/independent t tests. RESULTS The mean placement time, hemorrhage control time, and hemorrhagic scores were lower in Gp P than in Gp C, indicating better clinical performance of polymer-based retraction cord. Both groups showed an increase in sulcus width after retraction, but Gp P had a significantly higher sulcus width (690.03±45.37) compared to Gp C (471.38±28.13). The mean difference in sulcus width between baseline and after retraction was also significantly higher in Gp P (525.84 micrometers) than in Gp C (309.11 micrometers). CONCLUSIONS The present study shows that polymer-based cords produce more sulcus width and have better clinical performance compared to cotton-based gingival retraction cords. These results suggest that the use of polymer-based retraction cords can improve the quality of dental impressions in partially edentulous patients.

Prosthetic challenges in rehabilitating maxillomandibular trauma case: a multidisciplinary approach.

Although maxillofacial trauma is relatively common, it still presents a challenging management. Its management includes treatment of facial bone fractures, dentoalveolar trauma and soft tissue injuries as well as associated injuries. Plastic surgeons, maxillofacial surgeons and prosthodontists have an interest in the subject of maxillofacial injuries, particularly in the area of functional as well as aesthetical stomatognathic rehabilitation. Present case was a clinical scenario with maxillofacial trauma due to entanglement in agricultural equipment leading to fracture of palatal bone and fracture of mandible in symphysis region. The patient's mastication, phonetics, aesthetics and social life were affected. Initial management was performed by the plastic surgeons. Rehabilitation of maxillary defect was performed using fixed removable bridge with palatal extension to cover the cleft part, and cortical implant-supported fixed prosthesis was planned as the prosthetic treatment for mandibular arch. On follow-up, there was improvement in speech and mastication, and patient felt more confident in social interaction after prosthetic rehabilitation.

A promising era of immediate esthetic rehabilitation.

The extraction of a tooth in the anterior region can result in resorption of alveolar bone around the socket, especially the buccal bone leading to horizontal as well as vertical bone loss. This makes rehabilitation in the anterior region an esthetically complex situation. To preserve the buccal bone, the root is bisected and buccal two-thirds is preserved in the socket. This is called socket shield technique. Immediate implant placement and immediate provisionalization yield an esthetically pleasing and more acceptable outcome.

Radio frequency analysis of partially grafted immediate dental implant with and without use of static magnetic field: An in vivo study.

Background: Replacement of missing teeth with dental implants represents one of the most successful treatment modalities in modern dentistry. Patients desire for a shorter treatment time has made clinicians to attempt loading implants early or immediately after placement. The primary stability is determined by density and mechanical properties of the bone, the implant design, edentulous site complications, and the surgical technique. Various researchers have tried to achieve faster osseointegration static magnetic field is one of them. So the aim of this study was to investigate whether Static magnetic field created by using safer magnets was useful to promote osseointegration. Materials and Methods: Subjects were selected according to the predetermined inclusion and exclusion criteria in two groups (20 in each group). Conventional implant placement protocol was used and implant placement was performed and grafting was done. Magnetic healing cap was used in group I and conventional healing cap in group II. Implant stability assessment using radio frequency analyser was assessed at 2, 3 and 4 months on interval. Result: Mann-Whitney U test revealed that there was significant difference was observed between the groups I and II at 2, 3 and 4 months of interval (P < 0.001). Static magnetic field improve osseointegration in group I as compared to group II. Conclusion: The present double-blinded RCT showed significantly improved implant stability and osseointegration in implants which were stimulated by static magnetic field by using magnetic healing cap as compared to implants with conventional healing cap.

A Superior and Stable Electrocatalytic Oxygen Evolution Reaction by One-Dimensional FeCoP Colloidal Nanostructures.

Transition metal phosphides (TMPs) are expected to be excellent electrocatalysts for oxygen evolution reaction (OER) because of their high stability, highly conducting metalloid nature, highly abundant constituting elements, and the ability to act as a precatalyst due to in situ surface-formed oxy-hydroxide species. Herein, a "one-pot" colloidal approach has been used to develop a rod-shaped one-dimensional non-noble metal FeCoP electrocatalyst, which exhibits an excellent OER activity with an exceptionally high current density of 950 mA cm-2, a turnover frequency value of 7.43 s-1, and a low Tafel slope value of 54 mV dec-1. The FeCoP electrocatalyst affords OER ultralow overpotentials of 230 and 260 mV at current densities of 50 and 100 mA cm-2, respectively, in 1.0 M KOH, and demonstrates a superior catalytic stability of 10,000 cycles and durability up to 60 h at 50 mA cm-2. An insight into the superior and stable electrocatalytic OER performance by the FeCoP nanorods is obtained by extensive X-ray photoelectron spectroscopy, X-ray diffraction, Raman and infrared spectroscopy, and cyclic voltammetry analyses for a mechanistic study. This reveals that a high number of electrocatalytically active sites enhance the oxygen evolution and kinetics by offering metal ion sites for utilitarian in situ surface formation and adsorption of *O, *OH, and *OOH reactive species for OER catalysis.
