RESUMEN

BACKGROUND: Geranyl acetate, a compound found in plant oils, has been studied for its potential effects on renal and cardiovascular ailments. OBJECTIVE: This study aimed to investigate the diuretic and anti-hyperuricemic properties of geranyl acetate in male Wistar rats using a hyperuricemia-induced rat model. METHODS: Molecular docking studies were conducted to assess geranyl acetate's interactions with various targets. in vitro studies were performed to evaluate its scavenging ability and inhibition of xanthine oxidase, urease, and acetylcholinesterase. Subsequently, we administered different doses of geranyl acetate (25, 50, and 100 mg/kg) and a reference drug (furosemide) to the rats to assess their acute and repeated dose diuretic effects over seven days. To understand the diuretic mechanism, we used inhibitors, such as L-- NAME, indomethacin, and atropine, prior to administering geranyl acetate. We also tested the anti-hyperuricemic potential of geranyl acetate on hyperuricemic rats. RESULTS: Molecular docking suggested strong binding between geranyl acetate and nitric oxide synthase. in vitro studies showed significant free radical scavenging activity and and inhibition of acetylcholinesterase, xanthine oxidase, and urease. The 100 mg/kg dose exhibited the most promising diuretic effects, with nitric oxide appearing to influence its action. Uric acid excretion increased at this dose, resembling allopurinol effects. CONCLUSION: Geranyl acetate has demonstrated significant diuretic and anti-hyperuricemic effects, likely influenced by nitric oxide release and inhibition of enzymes, like xanthine oxidase and urease. The findings have suggested potential benefits for individuals with kidney ailments, hypertension, and gout.

RESUMEN

Objective: To analyze contemporary trends of dementia and dementia-related mortality in the United States between 1999 and 2020 categorized by demographic and regional attributes.Methods: A retrospective cohort analysis was conducted using mortality data from individuals aged 35 years to ≥85 years, where dementia/Alzheimer disease was recorded as a contributing or underlying cause of death. Data were extracted from the US Centers for Disease Control and Prevention's Wide-Ranging Online Data for Epidemiologic Research database for the years 1999-2020. Mortality rates adjusted for age due to dementia (annual age-adjusted mortality rate [AAMR]) per 10,000 individuals in the United States were categorized by gender, racial and ethnic groups, and geographic regions.Results: Results revealed 6,601,680 deaths related to dementia between 1999 and 2020. Among these, 85.5% were non-Hispanic (NH) white, 8% NH black, 4.34% Hispanic or Latino, 1.6% NH Asian or Pacific Islander, and 0.3% NH American Indian or Alaska Native adults. The overall AAMR was 17.49, with women experiencing a higher AAMR of 18.19 compared to men (16.05). Ethnic disparities were evident, with NH black adults having the highest AAMR (18.23), followed by NH white (18.09) and Hispanic adults (12.7). Over the study period, the overall AAMR increased from 10.86 in 1999 to 21.42 in 2020, with a notable 18.4% rise in the AAMR from 1999 to 2001. From 2001 to 2020, the average percent change of the AAMR was 1.0%. This upward trend in mortality was observed for both men and women and across all ethnicities.Conclusions: The study spanning 1999-2020 revealed concerning trends in dementia-related mortality in the United States. There is a critical need for targeted health care policy initiatives aimed at mitigating the increasing dementia burden.Prim Care Companion CNS Disord 2024;26(4):24m03724.

RESUMEN

Background: Ocular hygiene encompasses a spectrum of measures to initiate and maintain adequate ocular cleanliness to prevent eye infections and their further transmission. These infections affect all age groups and can lead to severe complications such as blindness. Nearly 1 billion cases could have been prevented out of over 2.2 billion people that are visually impaired worldwide. This bibliometric analysis focuses on the papers published on ocular hygiene and infections. Methods: We searched in the Scopus database from 2004 to 2024. After manual screening, a list of the 100 most-cited original articles was obtained, which was analysed for various factors, including temporal trends, subject areas, authorship patterns, country of origin, funding bodies, etc. Results: There has been a gradual decline over the past two decades in the number of publications. The United States was affiliated with the highest number of publications (n=61), followed by The United Kingdom (n=12) and Gambia (n=8). Several authors had 4 or more publications, with the highest number of publications by Rouse, B. T. (n=14). The American Journal of Ophthalmology takes the lead with 15 publications, while the National Eye Institute (n=23) was the leading funding body. Examination of institutional contributions shows that The University of Tennessee, Knoxville and UT College of Veterinary Medicine stand out with twelve publications each. Nearly half the publications belong to the field of medicine. However, significant publications also come from the fields Neuroscience, Microbiology and Immunology, Biochemistry, Genetics and Molecular Biology, etc. These findings highlight that there is great potential to conduct research to propagate ocular hygiene to prevent adverse effects of infections.

RESUMEN

The key purpose of the Study is to examine if institutional quality complements the relationship between Ownership Structure and Corporate Social Responsibility disclosure and performance in the light of legitimacy and agency theory. To the best of my knowledge, it is the first study in literature of finance. The sample comprises of 112 top-performing listed firms (based on market capitalization) at Pakistan Stock Exchange from 2010 to 2019. Institutional quality comprised of world governance indicators which is developed via principal component analysis, an instrumental variable approach and content analysis are used for CSR Disclosure Index to demonstrate the relationship between ownership structure and CSR. The resources complementary phenomenon is adopted to examine the institutional quality's role. Our results show significantly positive impact of Institutional and Foreign Ownerships on CSR while negative significant influence of CEO Duality and Family Ownership on CSR, suggesting that well governed firms will be more socially responsible. In addition, the findings suggest the institutional quality's positive moderating role on the relationship between ownership structure and CSR, signifying the institutional quality's complementary role for the weak corporate environment in Pakistan. Our findings are robust to a series of tests by using Generalized Method of Moment (GMM).

RESUMEN

Rotavirus gastroenteritis is accountable for an estimated 128 500 deaths among children younger than 5 years worldwide, and the majority occur in low-income countries. Although the clinical trials of rotavirus vaccines in Bangladesh revealed a significant reduction of severe rotavirus disease by around 50%, the vaccines are not yet included in the routine immunization program. The present study was designed to provide data on rotavirus diarrhea with clinical profiles and genotypes before (2017-2019) and during the COVID-19 pandemic period (2020-2021). Fecal samples were collected from 2% of the diarrheal patients at icddr,b Dhaka hospital of all ages between January 2017 and December 2021 and were tested for VP6 rotavirus antigen using ELISA. The clinical manifestations such as fever, duration of diarrhea and hospitalization, number of stools, and dehydration and so on were collected from the surveillance database (n = 3127). Of the positive samples, 10% were randomly selected for genotyping using Sanger sequencing method. A total of 12 705 fecal samples were screened for rotavirus A antigen by enzyme immunoassay. Overall, 3369 (27%) were rotavirus antigen-positive, of whom children <2 years had the highest prevalence (88.6%). The risk of rotavirus A infection was 4.2 times higher in winter than in summer. Overall, G3P[8] was the most prominent genotype (45.3%), followed by G1P[8] (32.1%), G9P[8] (6.8%), and G2P[4] (6.1%). The other unusual combinations, such as G1P[4], G1P[6], G2P[6], G3P[4], G3P[6], and G9P[6], were also present. Genetic analysis on Bangladeshi strains revealed that the selection pressure (dN/dS) was estimated as <1. The number of hospital visits showed a 37% drop during the COVID-19 pandemic relative to the years before the pandemic. Conversely, there was a notable increase in the rate of rotavirus positivity during the pandemic (34%, p < 0.00) compared to the period before COVID-19 (23%). Among the various clinical symptoms, only the occurrence of watery stool significantly increased during the pandemic. The G2P[4] strain showed a sudden rise (19%) in 2020, which then declined in 2021. In the same year, G1P[8] was more prevalent than G3P[8] (40% vs. 38%, respectively). The remaining genotypes were negligible and did not exhibit much fluctuation. This study reveals that the rotavirus burden remained high during the COVID-19 prepandemic and pandemic in Bangladesh. Considering the lack of antigenic variations between the circulating and vaccine-targeted strains, integrating the vaccine into the national immunization program could reduce the prevalence of the disease, the number of hospitalizations, and the severity of cases.

RESUMEN

Introduction: Despite a recent increase in the representation of female authors in scientific literature, a significant gap persists concerning the inclusion of women in research. This necessitates the analysis of published literature from a gender perspective. This study aimed to provide gender distribution in authorship in the 100 most-cited articles on food-borne pathogen outbreaks from 1990 to 2020. Methods: Bibliometric analysis was conducted using the Scopus database. Two reviewers were selected to search the database. We included the 100 most-cited articles on foodborne outbreak investigations. The analysis was conducted using Statistical Package for Social Sciences (SPSS) version 26 and Microsoft Excel version 2016. The citation data, including total citations, citations per year, and representation of women as first and senior authors, was analyzed in terms of frequencies, mean, median, and interquartile range. The correlation between journal impact factor and the representation of women in high-impact factor journals was determined. A p-value of <0.05 was considered significant. Results: Most of the top-cited articles were published between 2001 and 2010 (n=47). The top 3 most-cited articles were from the USA. Of the total 100 articles, women were the first and last authors in 46% and 28% of the articles, respectively, reflecting a significant gender gap. However, the proportion of females as principal investigators gradually increased from 25% (n=10/30) to 52% (n=24/47) during the period 2001-2010 and to 92% (n=12/13) during 2011-2020. The USA had the highest number of included articles (n=48), and women were principal authors in 56% (n=27) of them. The lowest representation of women was observed in Austria, Denmark, Japan, Netherlands, New Zealand, Nigeria, Portugal, and the United Kingdom. Conclusion: Women are under-represented in published literature on food-borne pathogen outbreaks. Although the representation of women as principal authors has recently increased, disparities still exist at the senior-author level, calling for women's advancement in academic science.

RESUMEN

PURPOSE: Several treatments have been in use for Demodex blepharitis, before the discovery of lotilaner, like tea tree oil and antibiotics; however, they either have irritable effects or systemic adverse effects, respectively. Lotilaner, a novel ectoparasiticide, has been proposed as a treatment for patients grappling with Demodex blepharitis. This review aims to assess the safety and efficacy of lotilaner in the treatment of Demodex blepharitis. DESIGN: Systematic review and meta-analysis. METHODS: An extensive search was conducted on PubMed, Cochrane Library, Scopus, and Google Scholar to find relevant literature till July 31, 2023 following the PRISMA guidelines. A total of 143 articles were retrieved by database searching, out of which 6 studies met the inclusion criteria and were included in the review. Four randomized controlled trials were included in the meta-analysis of mite eradication incidence. The review is registered with PROSPERO: CRD42023459997. RESULTS: Lotilaner is effective in eradicating Demodex mites in individuals suffering from Demodex blepharitis according to RR for the intervention versus the control group of 3.55 (95% confidence interval [CI]: 2.87-4.40, P < .00001, I2 = 0%). The meta-analysis of clinically meaningful collarette score revealed the summary RR for the intervention versus the control group was 3.15 (95% CI: 2.56-3.89, P < 0.00001, I2 = 27%). In conclusion, the results of the included studies were comparable and consistent. CONCLUSIONS: Our results indicated that lotilaner is an effective, well-tolerated, and promising drug in treating patients with Demodex blepharitis. Lotilaner administration and cost-effectiveness should now be contemplated for the study population as these constituents have a vital impact on its treatment success.

RESUMEN

OBJECTIVE: To evaluate the role of intraoperative neurophysiological monitoring (IONM) in reducing the postoperative neurologic deficit following corrective surgery of scoliosis. STUDY DESIGN: Observational Study. Place and Duration of the Study: Spine Surgery Department, Combined Military Hospital, Rawalpindi, from December 2022 to May 2023. METHODOLOGY: The study included 170 cases of scoliosis operated under multimodal IONM. Decreased amplitude of ≥50% in SSEP or 70-80% in MEPs were considered warning signs. Cases were divided into two groups: Group 1 (signal drop) and Group 2 (no signal drop). Group 1 was subdivided into Group 1a (true positive), Group 1b (false positive) and Group 1c (intermediate positive). Group 2 was subdivided into Group 2a (true negative) and Group 2b (false negative). RESULTS: Evoked potential changes were observed in 27 (15.9%) cases. This includes transient drop of signals in 16 (9.4%) and sustained drop of signals in 11 (6.5%) cases. Among sustained signal drop, 9 (5.29%) cases had exhibited postoperative neurological deficit whereas 2 (1.17%) cases did not show postoperative neurological deficit (false positive). Multimodal IONM in the current study shows sensitivity of 100%, specificity of 98.6%, positive predictive value of 92.6%, and negative predictive value of 100%. CONCLUSION: Multimodal IONM reduces the incidence of postoperative neurological deficit in corrective surgery of scoliosis by effectively detecting neurologic injury during surgery. Monitoring events alert surgical team to exercise immediate corrective measures which likely results in recovery of lost signals and predict the favorable outcome. KEY WORDS: Intraoperative monitoring, Motor evoked potentials, Neurological deficit, Scoliosis, Somatosensory evoked potentials.

RESUMEN

OBJECTIVE: To review the relationship between adiponectin levels and autism spectrum disorders (ASDs) in children. BACKGROUND: ASDs are associated with pervasive social interaction and communication abnormalities. Researchers have studied various pathophysiological mechanisms underlying ASDs to identify predictors for an early diagnosis to optimize treatment outcomes. Immune dysfunction, perhaps mediated by a decrease in anti-inflammatory adipokine, adiponectin, along with changes in other adipokines, may play a central role in increasing the risk for ASDs. However, other factors, such as low maternal vitamin D levels, atherosclerosis, diabetes, obesity, cardio-metabolic diseases, preterm delivery, and oxytocin gene polymorphism may also contribute to increased risk for ASDs. METHODS: Searches on the database; PubMed, Google Scholar, and Cochrane using keywords; adiponectin, adipokines, ASD, autism, autistic disorder, included English-language studies published till September 2022. Data were extracted on mean differences between adiponectin levels in children with and without ASDs. RESULTS: The search yielded six studies providing data on adiponectin levels in young patients with ASDs. As can be seen from Table 1, four of the six studies were positive for an inverse correlation between ASD and adiponectin levels. In addition, two of the four positive and one negative studies found low adiponectin levels associated with and the severity of autistic symptoms. However, results from one reviewed study were insignificant. CONCLUSION: Most studies reviewed yielded lower adiponectin levels in children with ASDs as well as the severity of autistic symptoms.

RESUMEN

To examine the potential for respiratory transmission of rotavirus, we systematically assessed if rotavirus RNA is detectable by real-time quantitative reverse transcription-polymerase chain reaction from nasal and oropharyngeal swab specimens of Bangladeshi children with acute rotavirus gastroenteritis. Forehead swabs were collected to assess skin contamination. Among 399 children aged <2 years hospitalized for gastroenteritis during peak rotavirus season, rotavirus RNA was detected in stool, oral, nasal and forehead swab specimens of 354 (89%). A subset was genotyped; genotype was concordant within a child's specimen set and several different genotypes were detected across children. These findings support possible respiratory transmission of rotavirus and warrant further investigation.

RESUMEN

Globally, cardiovascular disease (CVD) continues to be the primary cause of morbidity and mortality. The risk of cardiovascular disease is markedly increased in individuals with type 2 diabetes mellitus (T2DM), making managing cardiovascular health a top priority. Initially developed for their glucose-lowering properties, sodium-glucose cotransporter 2 (SGLT2) inhibitors have emerged as a transformative class of pharmaceuticals with profound cardiovascular benefits that extend far beyond glycemic control. One of the most striking findings is the substantial reduction in major adverse cardiovascular events (MACE), including myocardial infarction, stroke, and cardiovascular mortality, observed in clinical trials evaluating SGLT2 inhibitors. These extraordinary cardioprotective effects are demonstrated by landmark trials such as EMPA-REG OUTCOME, CANVAS, and DECLARE-TIMI 58, which are discussed in detail. In addition, SGLT2 inhibitors have demonstrated positive outcomes in heart failure (HF) with reduced ejection fraction, which has led to their incorporation into HF treatment guidelines. SGLT2 inhibitors offer renoprotection by delaying the progression of diabetic kidney disease, reducing albuminuria, preserving glomerular filtration rates, and their immediate cardiovascular benefits. We investigate the potential mechanisms underlying these renal benefits, focusing on the role of hemodynamic alterations and intraglomerular pressure reduction. In addition, SGLT2 inhibitors have a distinct diuretic effect that can contribute to volume reduction and symptom alleviation in patients with heart failure (HF). This diuretic action, distinct from conventional diuretics, warrants additional research to optimize their use in T2DM and HF patients. The risk of euglycemic diabetic ketoacidosis, genital mycobacterial infections, and bone fractures are also discussed. Understanding these issues is essential for making educated clinical decisions. In conclusion, SGLT2 inhibitors have transcended their initial function as anti-diabetic agents to become essential components of cardiovascular and renal protection strategies in T2DM patients. Their diverse benefits, which include cardioprotection, renoprotection, and the potential for HF management, highlight their potential to transform cardiovascular medicine. Optimizing the use of SGLT2 inhibitors in clinical practice bears the promise of improved cardiovascular outcomes for patients with T2DM and beyond as we navigate this changing landscape.
