RESUMEN

Target-based discovery of first-in-class therapeutics demands an in-depth understanding of the molecular mechanisms underlying human diseases. Precise measurements of cellular and biochemical activities are critical to gain mechanistic knowledge of biomolecules and their altered function in disease conditions. Such measurements enable the development of intervention strategies for preventing or treating diseases by modulation of desired molecular processes. Fluorescence-based techniques are routinely employed for accurate and robust measurements of in-vitro activity of molecular targets and for discovering novel chemical molecules that modulate the activity of molecular targets. In the current review, the authors focus on the applications of fluorescence-based high throughput screening (HTS) and fragment-based ligand discovery (FBLD) techniques such as fluorescence polarization (FP), Förster resonance energy transfer (FRET), fluorescence thermal shift assay (FTSA) and microscale thermophoresis (MST) for the discovery of chemical probe to exploring target's role in disease biology and ultimately, serve as a foundation for drug discovery. Some recent advancements in these techniques for compound library screening against important classes of drug targets, such as G-protein-coupled receptors (GPCRs) and GTPases, as well as phosphorylation- and acetylation-mediated protein-protein interactions, are discussed. Overall, this review presents a landscape of how these techniques paved the way for the discovery of small-molecule modulators and biologics against these targets for therapeutic benefits.

RESUMEN

Glioma coined as a "butterfly" tumor associated with a dismal prognosis. Marine algal compounds with the richest sources of bioactive components act as significant anti-tumor therapeutics. However, there is a paucity of studies conducted on Fucoidan to enhance the anti-glioma efficacy of Temozolomide. Therefore, the present study aimed to evaluate the synergistic anti-proliferative, anti-inflammatory and pro-apoptotic effects of Fucoidan with Temozolomide in in vitro and in silico experimental setup. The anti-proliferative effects of Temozolomide and Fucoidan were evaluated on C6 glioma cells by MTT and migration assay. Modulation of inflammatory markers and apoptosis induction was affirmed at the morphological and transcriptional level by dual staining and gene expression. Molecular docking (MD) and molecular dynamics simulation (MDS) studies were performed against the targets to rationalize the inhibitory effect. The dual-drug combination significantly reduced the cell viability and migration of glioma cells in a synergistic dose-dependent manner. At the molecular level, the dual-drug combination significantly down-regulated inflammatory genes with a concomitant upregulation of pro-apoptotic marker. In consensus with our in vitro findings, molecular docking and simulation studies revealed that the anti-tumor ligands: Temozolomide, Fucoidan with 5-(3-Methy1-trizeno)-imidazole-4-carboxamide (MTIC), and 4-amino-5-imidazole-carboxamide (AIC) had the potency to bind to the inflammatory proteins at their active sites, mediated by H-bonds and other non-covalent interactions. The dual-drug combinatorial treatment synergistically inhibited the proliferation, migration of glioma cells and promoted apoptosis; conversely with the down-regulation of inflammatory genes. However, pre-clinical experimental evidence is warranted for the possible translation of this combination.

RESUMEN

Highly active and earth-abundant electrocatalysts for the hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) are of great significance for sustainable hydrogen generation through alkaline water electrolysis. Here, with an aim to enhance the bifunctional electrocatalytic activity of cobalt molybdate towards overall water splitting, we demonstrate a simple method involving the modulation of the cobalt to molybdenum ratio and creation of phase-modulated heterointerfaces. Samples with varying Co/Mo molar ratios are obtained via a microwave-assisted synthesis method using appropriate starting precursors. The synthesis conditions are modified to create a heterointerface involving multiple phases of cobalt molybdenum suboxides (CoO/CoMoO3/Co2Mo3O8) supported on Ni foam (NF). Detailed electrochemical studies reveal that modulating the composition and hence the interface can tweak the bifunctional electrocatalytic activity of the material for HER and OER and thus improve the overall water splitting efficiency with very high durability over 500 h. To further evaluate the practical applicability of the studied catalyst in water splitting, an alkaline electrolyser is fabricated with the optimized cobalt molybdenum suboxide material (CMO-1.25) as a bifunctional electrocatalyst. A current density of 220 mA cm-2 @1.6 V and 670 mA cm-2 @1.8 V was obtained, and the device showed very good long-term durability.

RESUMEN

IMPORTANCE AND OBJECTIVE: Gastroesophageal reflux disease (GERD) is a chronic condition associated with several risk factors, but little is known about the association between hormone therapy (HT) and GERD in postmenopausal women. EVIDENCE REVIEW: We investigated the association between ever or current menopausal HT use and GERD using a systematic review and meta-analysis. Studies published between 2008 and August 31, 2022, were pooled using a DerSimonian and Laird random-effects model, and outcomes were reported as adjusted odds ratios (aOR) with a corresponding 95% CI. FINDINGS: The pooled analysis of five studies found a significant direct association between estrogen use and GERD (aOR, 1.41; 95% CI, 1.16-1.66; I2 = 97.6%), and progestogen use and GERD (two studies: aOR, 1.39; 95% CI, 1.15-1.64; I2 = 0.0%). The use of combined HT was also associated with GERD (1.16; 95% CI, 1.00-1.33; I2 = 87.9%). Overall, HT use was associated with 29% higher odds for GERD (aOR, 1.29; 95% CI, 1.17-1.42; I2 = 94.8%). The large number of pooled participants, differences in study design, geography, patient characteristics, and outcome assessment resulted in significant high heterogeneity. CONCLUSIONS AND RELEVANCE: There is a significant association between ever or current HT use and GERD. However, the results should be interpreted with caution, given the small number of included studies and high heterogeneity. This warrants careful evaluation of GERD risk factors when prescribing HT to reduce the risk of potential GERD complications.

RESUMEN

INTRODUCTION: Breast and cervical cancer are the leading causes of cancer death among women worldwide. Given the growing concern, cervical cancer awareness month (CCAM) in January and Breast cancer awareness month (BCAM) in October occur annually as global health observances to raise public awareness. This infodemiology study aimed to assess trends in public online searches for breast cancer and cervical cancer following the annual BCAM and CCAM from 2008 to 2021. METHODS: Google Trends (GT) was used to investigate online searches for "breast cancer" and "cervical cancer" from January 1, 2008, to December 31, 2021. (168 months). A joinpoint regression analysis was used to identify statistically significant weekly percentage changes (WPCs) and monthly percentage changes (MPCs) trends over time. RESULTS: Breast cancer searches increased in October (BCAM) every year, while cervical cancer searches increased in January (CCAM) in 2013, 2019, and 2020. Joinpoint regression analysis revealed a significant negative trend in "breast cancer" searches from 2008 to 2021 (MPC: -0.2%, 95% CI: -0.3 to -0.1) and an upward trend in "cervical cancer" searches from May 2017 to December 2021 (MPC: 0.5%, 95% CI: 0.2 to 0.7). CONCLUSION: Online searches on "breast cancer" remain consistently high only during BCAM, and "cervical cancer" has increased by 0.5% MPC since May 2017. Our findings can inform online interventions like event-based opportunities (BCAM and CCAM) and Google Ads to raise public awareness of breast and cervical cancer.

RESUMEN

Titanium and its alloys are widely used as implant materials for biomedical devices owing to their high mechanical strength, biocompatibility, and corrosion resistance. However, there is a significant rise in implant-associated infections (IAIs) leading to revision surgeries, which are more complicated than the original replacement surgery. To reduce the risk of infections, numerous antibacterial agents, e.g., bioactive compounds, metal ions, nanoparticles, antimicrobial peptides, polymers, etc., have been incorporated on the surface of the titanium implant. Various coating methods and surface modification techniques, e.g., micro-arc oxidation (MAO), layer-by-layer (LbL) assembly, plasma electrolytic oxidation (PEO), anodization, magnetron sputtering, and spin coating, are exploited in the race to create a biocompatible, antibacterial titanium implant surface that can simultaneously promote tissue integration around the implant. The nature and surface morphology of implant coatings play an important role in bacterial inhibition and drug delivery. Surface modification of titanium implants with nanostructured materials, such as titanium nanotubes, enhances bone regeneration. Antimicrobial peptides loaded with antibiotics help to achieve sustained drug release and reduce the risk of antibiotic resistance. Additive manufacturing of patient-specific porous titanium implants will have a clear future direction in the development of antimicrobial titanium implants. In this review, a brief overview of the different types of coatings that are used to prevent implant-associated infections and the applications of 3D printing in the development of antibacterial titanium implants is presented.

RESUMEN

Background: Frozen Sections (FS) are used to assess margins, for staging, and primary diagnosis. FS guide intraoperative treatment decisions in oncological gastro-intestinal tract surgeries and further management of the patients. Aim: To analyze the distribution, sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of frozen sections in gastrointestinal pathology in our institution during the period of 3 years (2016-2018). Material and Methods: This study was an audit to determine the accuracy of FS reports by comparing them with the paraffin section (PS) reports. The FS diagnoses and their PS diagnoses were noted in 1704 gastrointestinal surgeries during the period from 2016 to 2018. Discrepancies were noted and slides of discrepant cases were reviewed to determine the cause. Sensitivity, specificity, positive predictive value, negative predictive value, and accuracy were calculated using the standard formulae. Results: Out of 1704 cases, correct diagnosis on frozen section was made in 1649 cases (96.77%), 20 (1.17%) were deferred cases, and 35 (2.05%) were discrepant cases. The commonest discrepancies were seen in the primary diagnosis of the gall bladder and gastrectomy margins. The commonest causes for discrepancies were interpretation errors and technical errors. Sensitivity was 91.71%, specificity was 99.69%, positive predictive value was 98.84%, negative predictive value was 97.68%, and accuracy was 97.92%. Conclusion: FS diagnosis is a reliable guide to surgeons for intraoperative management. Studying deep cuts and careful sampling at frozen sections will help reduce discrepancies.

RESUMEN

BACKGROUND: Injury remains a major concern to public health in the European region. Previous iterations of the Global Burden of Disease (GBD) study showed wide variation in injury death and disability adjusted life year (DALY) rates across Europe, indicating injury inequality gaps between sub-regions and countries. The objectives of this study were to: 1) compare GBD 2019 estimates on injury mortality and DALYs across European sub-regions and countries by cause-of-injury category and sex; 2) examine changes in injury DALY rates over a 20 year-period by cause-of-injury category, sub-region and country; and 3) assess inequalities in injury mortality and DALY rates across the countries. METHODS: We performed a secondary database descriptive study using the GBD 2019 results on injuries in 44 European countries from 2000 to 2019. Inequality in DALY rates between these countries was assessed by calculating the DALY rate ratio between the highest-ranking country and lowest-ranking country in each year. RESULTS: In 2019, in Eastern Europe 80 [95% uncertainty interval (UI): 71 to 89] people per 100,000 died from injuries; twice as high compared to Central Europe (38 injury deaths per 100,000; 95% UI 34 to 42) and three times as high compared to Western Europe (27 injury deaths per 100,000; 95%UI 25 to 28). The injury DALY rates showed less pronounced differences between Eastern (5129 DALYs per 100,000; 95% UI: 4547 to 5864), Central (2940 DALYs per 100,000; 95% UI: 2452 to 3546) and Western Europe (1782 DALYs per 100,000; 95% UI: 1523 to 2115). Injury DALY rate was lowest in Italy (1489 DALYs per 100,000) and highest in Ukraine (5553 DALYs per 100,000). The difference in injury DALY rates by country was larger for males compared to females. The DALY rate ratio was highest in 2005, with DALY rate in the lowest-ranking country (Russian Federation) 6.0 times higher compared to the highest-ranking country (Malta). After 2005, the DALY rate ratio between the lowest- and the highest-ranking country gradually decreased to 3.7 in 2019. CONCLUSIONS: Injury mortality and DALY rates were highest in Eastern Europe and lowest in Western Europe, although differences in injury DALY rates declined rapidly, particularly in the past decade. The injury DALY rate ratio of highest- and lowest-ranking country declined from 2005 onwards, indicating declining inequalities in injuries between European countries.

RESUMEN

Kummell's disease (KD) is a delayed post-traumatic avascular osteonecrosis of the vertebral body secondary to a vertebral compression fracture that can present with back pain. We discuss the importance of an accurate diagnosis and appropriate management of Kummell's disease. Additionally, we aim to increase awareness and promote early diagnosis and treatment to prevent serious complications. A 55-year-old man had been diagnosed with avascular necrosis (AVN) of both hips and had a history of trauma to the left hip ten years ago. Between the initial fall and subsequent presentation, he resumed independent physical activity. At approximately 10 months following his initial injury, he returned to a local emergency department with vague complaints of lower back pain. He was prescribed analgesics for pain and discharged. Subsequently, he experienced a progressive increase in pain and complained of motor deficits of the lower limbs. He presented to our emergency room with acute onset of worsening pain. Magnetic resonance imaging revealed multiple-level compression fractures and a fluid cleft in the L2 intervertebral disc. Surgery was advised, but he did not consent. Therefore, nonsurgical treatment included bed rest, wearing a brace, lumbar traction, analgesics, and medication to prevent osteoporosis. Prompt, accurate diagnosis of Kummell's disease is important for timely, appropriate treatment, which can improve quality of life and prevent comorbidities.

RESUMEN

Value-added phytochemicals from food by-products and waste materials have gained much interest and among them, dietary polyphenolic compounds with potential biological properties extend a promising sustainable approach. Oxyresveratrol (Oxy), a stilbenoid polyphenol, possesses great therapeutic potential, though its pharmacokinetic issues need attention. A good source of oxyresveratrol was found in underutilized coconut shells and the synbiotic applications of the compound in combination with a potential probiotic isolate Limosilactobacillus fermentum ASBT-2 was investigated. The compound showed lower inhibitory effects on the strain with minimum inhibitory concentration (MIC) of 1000 µg/mL. Oxyresveratrol at sub-MIC concentrations (500 µg/mL and 250 µg/mL) enhanced the probiotic properties without exerting any inhibitory effects on the strain. The combination at sub- MIC concentration of the compound inhibited Salmonella enterica and in silico approaches were employed to elucidate the possible mode of action of oxy on the pathogen. Thus, the combination could target pathogens in the gut without exerting negative impacts on growth of beneficial strains. This approach could be a novel perspective to address the poor pharmacokinetic properties of the compound.

RESUMEN

Background: Older people often receive multiple medications for chronic conditions, which often result in polypharmacy (concomitant use of 5‒9 medicines) and hyperpolypharmacy (concomitant use of ≥10 medicines). A limited number of studies have been performed to evaluate the prevalence of polypharmacy, hyperpolypharmacy, and potentially inappropriate medication (PIM) use in older people of developing countries. The present study aimed to investigate regional variations in the prevalence of polypharmacy, hyperpolypharmacy, and PIM use in older people (60 + years) in India. Methods: Studies were identified using Medline/PubMed, Scopus, and Google Scholar databases published from inception (2002) to September 31, 2020. Out of the total 1890 articles, 27 were included in the study. Results: Overall, the pooled prevalence of polypharmacy was 49% (95% confidence interval: 42-56; p < 0.01), hyperpolypharmacy was 31% (21-40; p < 0.01), and PIM use was 28% (24-32; p < 0.01) among older Indian adults. Polypharmacy was more prevalent in North-east India (65%, 50-79), whereas hyperpolypharmacy was prevalent in south India (33%, 17-48). Region-wize estimates for the pooled prevalence of PIM use in India were as follows: 23% (21-25) in East, 33% in West (24-42), 17.8% in North (11-23), and 32% (26-38) in South India. The prevalence of PIM use in adults aged ≥70°years was 35% (28-42), in those taking more medications (≥5.5/day) was 27% (22-31), and in adults using a high number of PIMs (≥3) was 29% (22-36). Subgroup analysis showed that cross-sectional studies had a higher pooled prevalence of polypharmacy 55% (44-65) than cohorts 45% (37-54). Hyperpolypharmacy in inpatient care settings was 37% (26-47), whereas PIM use was higher in private hospitals 31% (24-38) than government hospitals 25% (19-31). Conclusion: Polypharmacy and hyperpolypharmacy are widely prevalent in India. About 28% of older Indian adults are affected by PIM use. Thus, appropriate steps are needed to promote rational geriatric prescribing in India. Systematic Review Registration: https://clinicaltrials.gov, identifier [CRD42019141037].

RESUMEN

Background: Older patients with type 2 diabetes mellitus (T2DM) are at greater risk of receiving potentially inappropriate medications (PIM) during hospitalization which may result in adverse outcomes. Aim: To evaluate the extent of PIM use in the older population with T2DM during hospitalization in a tertiary care hospital in India. Methods: A cross-sectional study was carried out from August 2019 to January 2020 in a tertiary care teaching hospital among the older population (aged ≥ 65 years) hospitalized with T2DM. Medications prescribed during hospitalization were reviewed following Beers Criteria 2019 to identify the extent of polypharmacy and PIM use. Binary logistic regression was applied to determine the factors associated with PIM use. Results: The mean age of the 150 patients hospitalized with T2DM was 68.85 ± 5.51 years, most of whom were men (54.7%). The participants had at least four comorbidities and were receiving an average of nine medications per day; the median length of hospital stay was 8 days (interquartile range (IQR): 4-19 days). Overall, three quarters (74%) of the participants had at least one PIM prescribed during their hospitalization as per Beers Criteria. Significant factors associated with the use of PIM during hospitalization are patients taking a higher number of medications (odds ratio (OR): 7.85, 95% CI 1.49-41.10), lower creatinine clearance values (OR: 12.90, 95% CI 2.81-59.28) and female patients (OR: 2.29; 95% CI: 1.05-4.97). Conclusions: PIM use is frequently observed in older T2DM patients during hospitalization. Polypharmacy, reduced renal function and female gender are associated with higher PIM use. Engaging clinical pharmacists in evaluating medication appropriateness can improve the outcomes of older patients.

RESUMEN

As of May 14, 2020, Italy has been one of the red hotspots for the COVID-19 pandemic. In particular, the regions of Emilia Romagna, Piedmont, and especially Lombardy were the most affected and had to face very serious health emergencies, which brought them to the brink of collapse. Since the virus has demonstrated local properties, i.e., greater severity and contagiousness in specific regions, the aim of this study is to model the complex behavior of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in Italy. In particular, we further investigated the results of other articles on the correlation with particulate matter pollution 10 (PM 10) and 2.5 (PM 2.5) by extending the research at the intra-regional level, as well as calculated a more plausible number of those infected compared to those officially declared by Civil Protection. Through a computational simulation of the Susceptible-Exposed-Infectious-Recovered (S.E.I.R.) model, we also estimated the most representative basic reproduction number [Formula: see text] for these three regions from February 22 to March 14, 2020. In doing so, we have been able to evaluate the consistency of the first containment measures until the end of April, as well as identify possible SARS-CoV-2 local behavior mutations and specificities.

RESUMEN

Acute pancreatitis (AP) is an uncommon potential complication of severe hypertriglyceridemia (HTG). We reported a case of a 45-year-old man admitted with HTG-induced AP (HTG-AP). The patient was a known diabetic (glycated hemoglobin levels: 9.5%), his triglycerides level was 3587.2 mg/dl, and the lipase level was 242 IU/L. A CT scan revealed AP. The patient was treated with a low-dose insulin infusion (0.05 unit/kg/hr) with dextrose for six days. His triglycerides came down to 673.1 mg/dl, and he was discharged. Further investigations are needed to understand the efficacy of low-dose insulin in the management of HTG-AP.

RESUMEN

The novel coronavirus disease 2019 (COVID-19) clinically manifests as respiratory and gastrointestinal presentations, most commonly vomiting, diarrhea, and abdominal pain. Although the impaired liver function is prevalent in COVID-19, it is poorly understood. We report the first case of hepatitis B virus (HBV) reactivation caused by COVID-19 in a young adult with altered mental status and severe transaminitis. The patient was asymptomatic, hypothermic, his skin was jaundiced with the icteric sclera, with very high levels of aspartate aminotransferase (AST; 4,933 U/L), alanine aminotransferase (ALT; 4,758 U/L), and total bilirubin (183.9 mmol/L) levels. It is warranted that patients with abnormal liver functions tend to have an increased risk of COVID-19. Thus, increased attention should be paid to the care of patients with abnormal liver functions, and testing for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) RNA is warranted in the COVID era.

RESUMEN

The ongoing novel coronavirus disease 2019 (COVID-19) pandemic has been responsible for millions of infections and hundreds of thousands of deaths. To date, there is no approved targeted treatment, and many investigational therapeutic agents and vaccine candidates are being considered for the treatment of COVID-19. To extract and summarize information on potential vaccines and therapeutic agents against COVID-19 at different stages of clinical trials from January to March 2020, we reviewed major clinical trial databases such as ClinicalTrials.gov, WHO International Clinical Trials Registry Platform (ICTRP), and other primary registries between January and March 15, 2020. Interventional studies at different phases under the COVID-19 pipeline were included. A total of 249 clinical trials were identified between January to March 15, 2020. After filtering observational studies (194 studies), a total of 56 interventional trials were considered. The majority of clinical trials have been conducted on chloroquine (n=10) and traditional Chinese medications (TCMs; n=10), followed by antivirals (n=8), anti-inflammatory/immunosuppressants (n=9), cellular therapies (n=4), combinations of different antivirals therapies (n=3), antibacterial (n=1), and other therapies (n=5). Five vaccines are under phase I, and there are a couple of phase III trials on the Bacillus Calmette-Guérin (BCG) vaccine under investigation among healthcare workers. Many novel compounds and vaccines against COVID-19 are currently under investigation. Some candidates have been tested for other viral infections and are listed for clinical trials against the COVID-19 pipeline. Currently, there are no effective specific antivirals or drug combinations available for the treatment of COVID-19.

RESUMEN

Tomato (Solanum lycopersicum) phytochemicals, which include phytoene, phytofluene, beta-carotene, flavonoids, lycopene, and polyphenols, have been shown to improve the effects of fasting on plasma triglyceride (TG), low-density lipoprotein cholesterol (LDL), high-density lipoprotein cholesterol (HDL), total cholesterol (TC), and fasting blood sugar (FBS). The aim of this study was to systematically evaluate the effects of Tomato TC, TG, HDL, LDL, and FBS in humans. A systematic literature search was conducted in PubMed/MEDLINE, Web of sciences, and SCOPUS databases by two researchers for studies published until August of 2019 without language and time limitations. Results were combined with random effect models. Six studies were included in this meta-analysis. Combined results reveal a significant reduction in cholesterol (weighted mean difference [WMD]: -4.39 mg/dl, 95% CI: -7.09, -1.68, I2 = % 48, p heterogeneity: .05), TG (WMD: -3.94 mg/dl, 95% CI: -7.67, -0.21, I2 = % 90, p heterogeneity: .001), LDL levels (WMD: -2.09 mg/dl, 95% CI: -3.73, -0.81, I2 = % 78, p heterogeneity: .001), and increasing in HDL levels (WMD: 2.25 mg/dl, 95% CI: 0.41, 4.10, I2 = % 97, p heterogeneity: .001). Tomato was found to have a higher reduction effect on TG and LDL in younger participants. While pooled results indicate no significant effect on FBS levels (WMD: 0.59 mg/dl, 95% CI: -0.28, 1.46, I2 = % 95, p heterogeneity: .001). In conclusion, the results indicate a significant reduction in total cholesterol, TG, and LDL and increase in HDL levels that is caused by tomato consumption.

RESUMEN

AIM: We investigated the incidence of adverse drug reactions (ADRs) in patients treated with statins for cardiovascular (CV) risk among the United Arab Emirates (UAE) population. METHODS: This is a retrospective cohort study conducted among statin users attending 2 tertiary care centres: Al Ain and Tawam hospitals in Al Ain city, UAE. We retrieved the clinical profile of all the patients taking statins from January 2011 to January 2015 using our electronic database (Cerner®). RESULTS: Among 556 patients (418 men; 138 women) taking statins, 237 ADRs were reported (186 men; 51 women). The incidence of ADRs was 40.7%, and was more frequent among patients at "high CV disease (CVD) risk" and "moderate CVD risk" than other risk categories. High CVD risk (odds ratio, 1.67; 95% confidence interval [CI], 1.19-2.34), vitamin D deficiency 1.45 (95% CI, 0.89-2.38), type 2 diabetes 1.22 (95% CI, 0.84-1.77) and hypertension 1.13 (95% CI, 0.70-1.83) are some of the factors that were associated with statin ADRs. CONCLUSION: The incidence of ADRs among statin users was 42.6%, and frequent ADRs (49%) were noted in patients with high CVD risk. Early identification of these ADRs should improve patient adherence to life-saving statin treatment.
