RESUMO

Objectives: To assess the characteristics of patients with heart failure with reduced ejection fraction (HFrEF) and heart failure with mid-range ejection fraction (HFmrEF), as well as the current application of guideline-directed medical therapy (GDMT) in Palestine. Methods: This retrospective cohort study involved a population of heart failure (HF) patients who visited cardiology clinics at An-Najah National University Hospital and the National Hospital, Palestine. The primary outcome measures of interest were the proportions of patients prescribed guideline-based cardiovascular medications (GBCMs), such as angiotensin-converting enzyme inhibitors (ACEIs)/angiotensin II receptor blockers (ARBs), ß-blockers, and mineralocorticoid receptor antagonists (MRAs), and the corresponding optimized doses at ≥ 50 % of targets and the reasons underlying the non-prescription of GDMT. Results: A total of 70.5%, 56.6%, and 88.6% of patients were on ACEIs/ARBs, MRAs, and ß-blockers, respectively. Of all patients, 38.7% were on the triple GDMT regimen. Conclusion: Less than half the patients received the triple combination treatment. Age, diabetes mellitus, chronic renal disease, and admission to the hospital for HF all had significant independent relationships with the reduced utilization and inadequate dosage of GDMT.

RESUMO

Background: The escalating worldwide concerns for mental health, significantly amplified by the COVID-19 pandemic, necessitates understanding the impact on vulnerable populations, such as university students. This study aims to investigate the prevalence and implications of depression, anxiety, and stress among university students in the United Arab Emirates (UAE) using the Depression, Anxiety, and Stress Scale-21 Items (DASS-21). Methods: This study utilized convenience sampling to investigate the mental health of undergraduates in UAE universities using a bilingual DASS-21 questionnaire via Google Forms. Analysis was conducted using SPSS version 29.0, employing descriptive statistics, Chi-squared tests, Mann-Whitney tests, Kruskal-Wallis tests, and Multinomial Logistic Regression to analyze relationships between sociodemographic variables and mental health scores. Results: The study examined 332 students, with most female participants (81 %, n = 269) and individuals aged 18-20 (89.8 %, n = 298). It revealed higher mean DASS scores among females: Depression (M = 15.80, p = 0.030), Anxiety (M = 17.63, p < 0.001), and Stress (M = 22.61, p < 0.001). Fourth-year students exhibited the highest DASS scores for depression (M = 30.33, p = 0.002), anxiety (M = 21.33, p = 0.002), and stress (M = 27.00, p = 0.005). Younger participants aged 18-20 had an odds ratio (OR) of 4.925 for depression, indicating they were approximately five times more likely to experience depression. Conclusions: This study reveals gender, age, and academic-year variations in depression, anxiety, and stress among UAE university students. Specifically, our findings indicate higher levels of anxiety and stress among females and reveal academic-year and age-related patterns in mental health conditions. University support services in the UAE should better address student needs, including counseling focused on high school to university transition challenges.

RESUMO

Disruptions to iron metabolism and iron homeostasis have emerged as significant contributors to the development and progression of Alzheimer's disease (AD). Human transferrin plays a key part in maintaining iron equilibrium throughout the body, highlighting its importance in AD. Many plant-derived compounds and dietary constituents show promise for preventing AD. Polyphenols that are abundant in fruits, vegetables, teas, coffee, and herbs possess neuroprotective attributes. Resveratrol is a natural polyphenol present in various plant sources like grapes, berries, peanuts, and red wine that has garnered research interest due to its wide range of biological activities. Notably, resveratrol exhibits neuroprotective effects that may help prevent or treat AD through multiple mechanisms. In the present study, we employed a combination of molecular docking and all-atom molecular dynamic simulations (MD) along with experimental approaches to unravel the intricate interactions between transferrin and resveratrol deciphering the binding mechanism. Through molecular docking analysis, it was determined that resveratrol occupies the iron binding pocket of transferrin. Furthermore, MD simulations provided a more profound insight into the stability and conformational dynamics of the complex suggesting that the binding of resveratrol introduced localized flexibility, while maintaining overall stability. The spectroscopic observations yielded clear evidence of substantial binding between resveratrol and transferrin, confirming the computational findings. The identified binding mechanism and conformational stability hold potential for advancing the development of innovative therapeutic approaches targeting AD through resveratrol, particularly concerning iron homeostasis. These insights serve as a platform for considering the natural compounds in the realm of AD therapeutics.

RESUMO

ß-secretase 1 (BACE1) is an enzyme that is involved in generating beta-amyloid peptides and is believed to have a significant role in the development of Alzheimer's disease (AD). Therefore, BACE1 has gained attention as a potential therapeutic target for treating AD. Modern drug discovery studies are being conducted to identify potential inhibitors of BACE1, with the goal of reducing the production of beta-amyloid peptides and, thus, slowing the progression of AD. Here, we used a multistep virtual screening methodology to identify phytoconstituents from the IMPPAT library that could inhibit the activity of BACE1. Molecular docking was employed to select initial hits based on their binding affinity toward BACE1. Screening for PAINS patterns, ADMET and PASS properties, was then used to identify potential molecules for BACE1 inhibition. In the end, we discovered two natural compounds, Peiminine and 27-Deoxywithaferin A, which demonstrated a strong affinity, effectiveness, and specific interactions for the BACE1-active site. The elucidated molecules also displayed drug likeliness. A 200 ns molecular dynamics (MD) simulation was conducted to investigate the interaction mechanism, complex stability, and conformational dynamics of BACE1 with Peiminine and 27-Deoxywithaferin A. The MD simulations demonstrated that BACE1 was stable during the simulation with Peiminine and 27-Deoxywithaferin A. Overall, the results suggested that Peiminine and 27-Deoxywithaferin A hold significant potential as scaffolds in drug development efforts targeting BACE1 for the purpose of treating AD.

RESUMO

BACKGROUND: This study was conducted among a convenience sample of Ajman University students in UAE between February 2018 and May 2019. METHODS: All undergraduate and master's degree students from the 1st to 5th year of medical and non-medical colleges. The survey was carried out by distributing a pre-designed, pre-structured questionnaire to the students during lectures. The questionnaires were primarily composed of three sections: demographic characteristics, educational characteristics and sleep quality characteristics. The data were analyzed using STATA version 14.2. Logistic regression analysis was used to investigate the association between sleep characteristics, social media use and other significant risk factors. The P-values < 0.05 were considered to be statistically significant. RESULTS: The vast majority of the study participants were social media users, and a considerable proportion suffered from poor sleep quality. A significantly increased risk of bad sleep quality and intermittent/anxious sleep patterns were observed among social media users. CONCLUSION: Health policymakers should fully consider these factors in improving the sleep quality of university students.

RESUMO

The role of airport pharmacies has grown in recent years to provide a range of services to travelers, including over-the-counter and prescription medicines, as well as advice on prevention of infectious and other diseases. Prevention, including protective equipment, is especially important during pandemics, as seen with the recent coronavirus disease-2019 (COVID-19) pandemic. In addition, offering vaccinations where appropriate. However, this is not universal, and there are currently no acknowledged guidelines for pharmacists operating within airports. In addition, research into their role as well as potential ways to improve this is lacking. This is a concern with community pharmacists playing a valuable role during the COVID-19 pandemic. Potential ways forward include greater research into their activities to enhance their role and address challenges. These include issues of brand names and language, as well as encouraging travel pharmacy in future university curricula. In addition, producing guidelines for their activities and monitoring their implementation. This can help build a greater role for their services, benefiting airport staff and travelers in the future.

RESUMO

BACKGROUND: Significant links between the microbiota and human health have emerged in the last 20 years. A correlation has recently been demonstrated between changes in the gut microbiota and the development of cancer. This study aimed to use bibliometric analysis of the published gut microbiome and cancer literature to present the research status and summarize the hotspots for frontier studies. METHODS: A literature search for research on the gut microbiome and cancer research from 2001 to 2020 was conducted using the Scopus database on 20 March 2021. VOSviewer software (version 1.6.16) was used to perform the visualization analysis. RESULTS: From 2001 to 2020, a total of 2061 publications were retrieved. Annual publication output grew from 10 in 2001 to 486 in 2020. The USA had the largest number of publications, making the largest contribution to the field (n = 566, 27.46%). Before 2016, most studies focused on the 'effect of probiotics on cancer'. The latest trends showed that 'microbiota composition and gene expression' and 'host-microbiome interaction in cancer immunotherapy' would be more concerned more widely in the future. CONCLUSIONS: Research on 'microbiota composition and gene expression' and 'host-microbiome interaction in cancer immunotherapy' will continue to be the hotspot. Therefore, this study provides the trend and characteristics of the literature on the gut microbiota and cancer literature, which provided a useful bibliometric analysis for researchers to conduct further research.

RESUMO

BACKGROUND: District hospitals are crucial in supporting primary health care and serve as a gateway to more specialist care through a referral system. Majority of South Africans access health care services through the public sector district health system. Given the enormous task assigned to the public district hospital within the country, this study examined factors influencing their technical efficiency. METHOD: Data were collected for 38 public district hospitals in KwaZulu-Natal province from 2014/15 to 2016/17. Data envelopment analysis (DEA) was used to determine the technical efficiency of the hospitals, adopting both the constant return to scale (CRS) and variable return to scale (VRS) models. Tobit regression model was used to determine factors related to the technical efficiency of the district hospitals. RESULTS: This study showed that a significant proportion of the district hospitals were technically inefficient. The Tobit regression model identified catchment population, the proportion of inpatients treated per medical personnel, the proportion of inpatients treated per nursing personnel and expenditure per patient day equivalent as factors influencing technical efficiency of the district hospitals. CONCLUSION: Findings from this study suggest that the technical efficiency of the district hospitals can be enhanced through an effective referral system and improved peoples' health-seeking behaviour. In addition, a standard mix of clinical staff toward efficient service delivery and periodic cost analysis of health services with the view to saving cost and maintaining the quality of health care should be considered.

RESUMO

Thalassemia is humanity's most common genetic disorder and represents a serious healthcare challenge in the United Arab Emirates. Increasing awareness is a crucial part of any successful strategy to prevent thalassemia. This research examined knowledge levels and attitudes regarding thalassemia screening, counseling, and monitoring from medical and nonmedical students at Ajman University. This was a cross-sectional, descriptive study conducted among a convenience sample of Ajman university students in the UAE. A questionnaire was distributed which was composed of three main sections. The first section covered participants' demographic data. The second section covered general knowledge of thalassemia and its screening measures. The third section assessed risk factors, regulations, and preventive measures. The data were analyzed using the statistical package for social sciences (SPSS) version 24. A total of 523 participants completed the whole survey. Generally, there was a good level of awareness of thalassemia and thalassemia screening among participants. Approximately three-quarters of participants (76.5%) agreed that thalassemia screening should be compulsory for the individual and the majority of students and 92.7% recognized the importance of thalassemia screening for both partners. Approximately three-quarters (75.9%) of participants disagreed that fetuses with thalassemia should be aborted. More than half of the participants disagreed that thalassemia carriers and patients should be prevented from marrying each other. Generally, older respondents (final year students), respondents who had dealt with thalassemia patients, and respondents with relatives with thalassemia had more comprehensive knowledge of thalassemia. Campaigns focusing on college and university students should be regarded as an essential element of the thalassemia prevention strategy for contemporary UAE society.

RESUMO

Human serum albumin (HSA) is the most abundant protein in plasma synthesized by the liver and the main modulator of fluid distribution between body compartments. It has an amazing capacity to bind with multiple ligands, offering a store and transporter for various endogenous and exogenous compounds. Huperzine A (HpzA) is a natural sesquiterpene alkaloid found in Huperzia serrata and used in various neurological conditions, including Alzheimer's disease (AD). This study elucidated the binding of HpzA with HSA using advanced computational approaches such as molecular docking and molecular dynamic (MD) simulation followed by fluorescence-based binding assays. The molecular docking result showed plausible interaction between HpzA and HSA. The MD simulation and principal component analysis (PCA) results supported the stable interactions of the protein-ligand complex. The fluorescence assay further validated the in silico study, revealing significant binding affinity between HpzA and HSA. This study advocated that HpzA acts as a latent HSA binding partner, which may be investigated further in AD therapy in experimental settings.

RESUMO

This paper reports an important investigation and quantification of adulteration of sexual enhancement supplements with prescription medicines available in United Arab Emirates (UAE): tadalafil, sildenafil and vardenafil. A total of 158 sexual enhancement supplements were collected and analyzed in the current study. The samples were screened using REVERSE-phase liquid chromatography tandem high-resolution mass spectrometry/mass spectrometry (RP-HPLC-MS/MS). Of all sexual enhancements, 12.7% (95% CI: 7.4-18) contained undeclared sildenafil, 3.8% (95% CI: 0.78-6.81) contained undeclared tadalafil and 1.9% (95% CI: 0.25-4.05) contained undeclared vardenafil. Of all sexual enhancement supplements, 13.9% (95% CI: 8.5-19.4) contained significant concentrations of sildenafil, tadalafil or vardenafil. While the study found relatively low levels of undeclared pharmaceutical ingredients in the sexual enhancement dietary supplements available on the UAE market, it is likely that patients with ED tend to consume multiple such supplements daily, thereby exposing themselves to highly elevated cumulative levels.

RESUMO

This study aimed to assess the patterns of social media usage amongst university students at Ajman University (AU) and to explore health issues in relation to social media use. A cross-sectional community-based descriptive research design was conducted among AU students. A pre-designed, structured and validated questionnaire written in both English and Arabic was employed to collect data from the participants. The structured questionnaire was mainly composed of three sections: demographic and educational information, social media usage pattern information and poor health status. A total of 444 students participated in the study and completed the whole questionnaire. Over half the respondents (60.8%) reported using social media on more than 3 days during the past week; more than a quarter (28.6%) reported using social media for over 4 h each day; and almost half (44.1%) reported going on social media in the hour prior to going to bed. Overall, 390 (84.1%) respondents gave a higher poor health status score and 74 (15.9%) gave a lower one. Students who were active on Facebook tended to score higher in terms of poor health status than students who used other social media platforms. Moreover, those respondents who used social media for communication and enjoyment had higher poor health status scores. The findings of this study highlight the urgent need to address the increasing use of social media among adolescents-particularly university students-for example through educational interventions or campaigns aiming to encourage sensible social media practices.

RESUMO

Weight loss supplements that have illegal additives of pharmaceutical drugs or analogues have additional health risks, and customers may not be aware of what they are taking. This research is an essential investigation and quantification of illegally added pharmaceuticals or prescription medications, specifically fluoxetine, phenolphthalein, and sibutramine, in herbal weight loss supplements offered for sale in the United Arab Emirates (UAE). In this case, 137 weight loss supplements were collected and analyzed in this study. Reversed-phase high-performance liquid chromatography with UV absorption detection coupled to tandem mass spectrometry (RP-HPLC-MS/MS) analyses were used to determine the presence of the pharmaceutical chemicals. Among the weight loss supplements, 15.3% (95% CI: 9.2-21.4) contained undeclared sibutramine, 13.9% (95% CI: 8.01-19.7) contained undeclared phenolphthalein, and 5.1% (95% CI: 1.4-8.8) contained undeclared fluoxetine. Amongst all weight loss supplements, 17.5% (95% CI: 11.07-24) contained significant concentrations of either sibutramine, phenolphthalein, or fluoxetine. Whilst weight loss herbal supplements offered for sale in the UAE have relatively low percentages of undeclared pharmaceuticals, many people take several different supplements daily and may encounter quite high levels of combined exposure to toxic compounds.

RESUMO

BACKGROUND: Since the time of declaration of global pandemic of COVID-19 by World Health Organization (WHO), falsified hand sanitizers surfaced regularly in markets, posing possible harm to public due to unlisted inclusion of methanol. The current research is an attempt to develop and validate a tool to document falsified hand sanitizer in the UAE community. METHOD: A descriptive cross-sectional community-based study was conducted among 1280 randomly selected participants. Respondents were sent a web-based electronic link to the survey via email. Content validity, factor analyses and known group validity were used to develop and validate a new scale to identify falsified hand sanitizer. Test-retest reliability, internal consistency, item internal consistency (IIC), and intraclass correlation coefficients (ICCs) were used to assess the reliability of the scale. SPSS version 24 was used to conduct data analysis. RESULTS: A total of 1280 participants were enrolled in the study. The content validity index (CVI) was 0.83 with the final scale of 12 items. The Kaiser-Meyer-Olkin (KMO) value was 0.788, with the Bartlett test of sphericity achieving statistical significance (p < 0.001). Our factor analysis revealed a 3-component model. The 3-factor solution was confirmed by PCFA analysis and had associations with good fit values. The PCFA for NFI was 0.970, CFI 0.978, and TLI 0.967. All values were in excess of 0.95, with RMSEA values below 0.06 at 0.03; all of these values indicated a good model fit. The Cronbach's alpha was good overall (0.867). All factors had a Cronbach's alpha value in excess of 0.70. The instrument demonstrated that every item met the IIC correlation standard ≥0.40. The scale displayed good overall ICC statistics of 0.867 (95% CI 0.856-0.877) with statistical significance (p < 0.001). The scale's test-retest reliability was assessed through correlation of the falsified hand sanitizer identification score of respondents at the two time points. The test-retest correlation coefficient was 0.770 (p value < 0.01). Participants with post-graduate education were more likely to identify the falsified hand sanitizer compared to those with high school education. (p < 0.001). CONCLUSIONS: This study developed and validated a new scale for the measurement of falsified hand sanitizer. This is expected to improve and promote collaboration between the health regulators and the public and hereby encourage customer satisfaction and participation.

RESUMO

BACKGROUND: Antibiotic resistance became a marker of irrational and overuse of these medicines in many countries. This study aims to evaluate the knowledge, attitude and practice (KAP) of medical students (MS) and non-medical students (NS) towards antibiotic use in the United Arabs Emirates (UAE). METHOD: A descriptive cross-sectional study was conducted amongst 1200 MS and NS from Ajman University in UAE. A self-administered questionnaire was used to assess the knowledge, attitude and practice of antibiotic use. The later was composed into knowledge, attitude and practice of antibiotic use. Descriptive analysis was used to analyse the qualitative variables while quantitative variables were summarised using mean ± Standard Deviation (±SD). A Chi-square test was used to compare differences in the proportions of qualitative variables. Unpaired student's t-test was used to test the average differences in quantitative variables across medical and non-medical students. A p < 0.05 was considered statistically significant. RESULTS: One thousand two hundred students (MS: 600 and NS: 600) were considered valid for analysis. On average, participants scored higher in attitude score followed by knowledge and practice scores. The average attitude score was 76% (95% CI: [75, 78%]) compared to 59% for knowledge (95% CI: [58, 60%]) and 45% (95% CI: [44, 47%]) for practice. The results suggest that overall, medical students scored remarkably better than non-medical students on KAP of antibiotic use, respectively (p = 0.0001), (p = 0.000) and (p = 0.002). CONCLUSION: The students' knowledge, attitude and practice regarding antibiotic use, which drive the practice of self-medication, reflect a gap in medical curricula in UAE institutes and medical colleges.

RESUMO

Oral carcinoma is the sixth most common cancer globally, with one death occurring every hour. Focal adhesion kinase (FAK) is an intercellular protein tyrosine kinase, a key indicator of the development of oral cancer. FAK overexpression leads to the initiation and significant progression of metastasis in head and neck cancers, indicating its vital role in cancer progression and potential as a biomarker for early oral malignant transformation. The present review elaborates on FAK's function in oral malignancies since it could serve as a biomarker of the initial stages of oral malignant transformation and a possible predictive factor for risk assessment.

RESUMO

Background: HMGCS2 (mitochondrial 3-hydroxy-3-methylglutaryl-COA synthase 2) plays a pivotal role as a control enzyme in ketogenesis, and its association with the amyloid-ß protein precursor (AßPP) in mitochondria implicates a potential involvement in Alzheimer's disease (AD) pathophysiology. Objective: Our study aimed at identifying repurposed drugs using the DrugBank database capable of inhibiting HMGCS2 activity. Methods: Exploiting the power of drug repurposing in conjunction with virtual screening and molecular dynamic (MD) simulations against 'HMGCS2', we present new in-silico insight into structure-based drug repurposing. Results: The initial molecules were screened for their binding affinity to HMGCS2. Subsequent interaction analyses and extensive 300 ns MD simulations were conducted to explore the conformational dynamics and stability of HMGCS2 in complex with the screened molecules, particularly Penfluridol and Lurasidone. Conclusions: The study revealed that HMGCS2 forms stable protein-ligand complexes with Penfluridol and Lurasidone. Our findings indicate that Penfluridol and Lurasidone competitively bind to HMGCS2 and warrant their further exploration as potential repurposed molecules for anti-Alzheimer's drug development.

In present times, a switch from chemical molecules towards natural products is taking place, and the latter is being increasingly explored in the management of diseases due to their broad range of therapeutic potential. Consumption of coffee is thought to reduce Alzheimer's disease (AD); however, the mechanism is still unexplored. Primarily, it is thought that components of coffee are the key players in making it a neuroprotectant. Caffeic acid (CA) is found in high quantities in coffee; thus, it is being increasingly explored to decipher its neuroprotection by various mechanisms. Iron is a toxic element in a free form capable of causing oxidative damage and ultimately contributing to the pathogenesis of AD. Thus, maintaining the proper iron levels is vital and human transferrin (Htf), a glycoprotein, is a key player in this aspect. In this work, we explored the binding mechanism of CA with Htf at the atomistic level, employing molecular docking and extensive molecular dynamics simulation (MD) approaches coupled with spectroscopic techniques in a bid to decipher the mode of interaction of CA with Htf. Molecular docking results demonstrated a strong binding affinity between CA and Htf. Furthermore, MD study highlighted the Htf-CA complex's stability and the ligand's minimal impact on Htf's overall structure. In silico approaches were further backed up by experimental approaches. Strong binding of CA with Htf was ascertained by UV-visible and fluorescence spectroscopy observations. Together, the study provides a comprehensive understanding of the Htf-CA interaction, adding to the knowledge of the use of CA in the treatment of AD, thereby adding another feather to its already known neuroprotective role.
