RESUMEN
Nasal ions environment plays a crucial role in maintaining nasal physiology and supports olfactory transmission. Addressing the limited research on nasal ion levels and their association with olfactory function, paper-based sensors were developed for determination of sodium, potassium, calcium and chloride in the nasal mucus of healthy volunteers and patients with olfactory dysfunction. Multi-walled carbon nanotubes and carbon quantum dots from beetroot were incorporated into paper substrate where sensors were designed with ion association complexes for sodium, potassium, calcium and chloride enhancing the recognition sensing capabilities. The sensors composition was optimized, including ion-exchange materials and plasticizers, to enhance sensitivity and selectivity. The performance of the sensors is evaluated based on Nernstian slope, dynamic range, detection limit and response time. Selectivity of the sensors was tested and the results demonstrated high selectivity for the target ions. The sensors were successfully determined sodium, potassium, calcium and chloride levels in nasal mucus of healthy volunteers and patients with olfactory dysfunction. The results revealed elevated calcium levels in patients with olfactory dysfunction, highlighting associated diagnostic implications. This suggests that the proposed sensors could serve as a diagnostic tool for olfactory evaluation, particularly in resource-constrained settings where access to advanced diagnostic tools is limited.
RESUMEN
Futibatinib is a powerful inhibitor of fibroblast growth factor receptors that impedes its phosphorylation and subsequently leading to a reduction in in cell viability across various cell lines. Futibatinib was approved for initial use as an effective treatment for several diseases, including non-small cell lung cancer and breast cancer. Herein, a novel selective fluorescence probe was created for futibatinib quantification in various matrices, including pharmaceutical formulation and human plasma. The technique primarily depends on futibatinib's chemical conversion into a fluorescent product through a reaction with trimethylamine and bromoacetyl bromide. The created fluorescent probe exhibits maximum emission peak at 338 nm upon excitation at 248 nm. The method provided a low detection limit of 0.120 ng/mL and maintained a linear concentration-dependent relationship across the range of 1-200 ng/mL. High sensitivity, accuracy and precision were demonstrated for futibatinib quantification in pharmaceutical formulation and spiked plasma matrix by the method, which was validated in accordance with ICH requirements.

Objective: Chronic diseases hold the potential to worsen the overall health of patients by limiting their functional status, productivity, and capacity to live well, affecting their overall health-related quality of life (HRQoL). The purpose of the study was to assess the HRQoL of individuals with chronic diseases residing in the Al-Jouf region of Saudi Arabia. Furthermore, the current study also sought to ascertain the impact of multimorbidity and the duration of illness on HRQoL. Material and Methods: A cross-sectional study was conducted among the residents of Al-Jouf region for a period of 6 months. A self-administered EuroQoL (EQ-5D-5L) study tool was used. Appropriate statistical analysis was conducted to ascertain the relationship between various variables and HRQoL. Results: A total of 500 out of 562 participants completed the study, with a response rate of 88.97%. Participants had a mean age of 46.15 ± 16.79 years, and the majority were female (n = 299; 59.80%). A mean HRQoL score of 0.82 ± 0.20 was reported, poorest in patients with kidney failure (0.65 ± 0.26) and highest in hepatitis. However, nearly half of the participants had diabetes mellitus type II (n = 205, 39.20%). Patients aged <30 years (OR: 0.109; p = 0.002), male participants (OR: 0.053; p < 0.001), no disability (OR: 0.143; p = 0.002), and <2 comorbid diseases (0.84 ± 0.18; p < 0.001) reported better QoL. Additionally, comorbid conditions such as DM, prolong the duration of the overall illness (14.19 ± 7.67 years). Overall, imperfect health (n = 390, 78%) was reported by the study participants. Conclusion: The present study provided preliminary data about the current HRQoL status of individuals with imperfect health and lower HRQoL. In the future, large-scale longitudinal studies are required to investigate the most prevalent chronic diseases, their associations, and change in HRQoL, as there is a dearth of information in the Saudi population.
RESUMEN
Ionic microenvironment of the nasal secretions especially calcium ions play essential role in the olfactory transmission. However, there is a critical need to determine the free calcium levels in healthy people's nasal secretions in contrast to those of patients with olfactory impairment. A selective spectrofluorometric method was created to quantify nasal calcium levels utilizing its quenching ability to the fluorescence of the functionalized carbon quantum dots. The surface of carbon quantum dots was functionalized with calcium ionophore A23187 and ion association complex, calcium phosphotungstate, to improve the selectively to quantify calcium ions. The functionalized carbon quantum dots exhibited a concentration-dependent fluorescence quenching upon interaction with calcium ions. Different factors influencing the quenching process were done to provide efficient analytical process. The new method, demonstrated accurate calcium determination over the concentration range of 200-4000 ng/mL. The suggested technique was used to measure the calcium in the nasal secretions of both healthy people and patients with olfactory impairment. The findings revealed significantly higher calcium levels in the patient with olfactory dysfunction (healthy vs. patient; 735 ± 20 ng/mL vs. 2987 ± 37 ng/mL, p < 0.05).

Finerenone, a non-steroidal mineralocorticoid receptor antagonist, has gained recent approval for treating cardiovascular and kidney-related conditions. Herein, an innovative fluorescence chemo sensor was developed for the determination of finerenone in the pharmaceutical dosage form and the plasma matrix. The method is basically based on chemical transformation of finerenone into a fluorescent product through sequential reactions. This transformation occurs through a sequence of steps involving the interaction of finerenone with trimethylamine, resulting in the formation of a nucleophilic intermediate that subsequently reacts with bromoacetyl bromide to form fluorescent product, (S)-N-(2-bromoacetyl)-4-(4-cyano-2-methoxyphenyl)-5-ethoxy-2,8-dimethyl-1,4-dihydro-1,6-naphthyridine-3-carboxamide. The formed fluorescent product exhibits defined emission peak at 338 nm when excited at 248 nm. Significant concentration-dependent fluorescence enhancement was obtained enabling precise finerenone determination in the pharmaceutical formulation and plasma matrix. The method was optimized and validated providing sensitive determination over linearity range of 1-200 ng/mL with a lower limit of detection at 0.280 ng/mL. This strategy provides an efficient, economical substitute and straightforward, more sensitive analytical method for finerenone assessment in various matrices, in contrast to the previously published method, high-performance liquid chromatography-tandem mass spectrometry, which is expensive and time-consuming.

Herein, two different sustainable and green signal processing spectrophotometric approaches, namely, derivative spectroscopy and wavelet transform, have been utilized for effective measurement of the antiretroviral therapy abacavir and lamivudine in their pharmaceutical formulations. These methods were used to enhance the spectral data and differentiate between the absorption bands of abacavir and lamivudine in order to accurately measure their concentrations. For determining abacavir and lamivudine, the first derivative spectrophotometric method has been applied to the zero-order and ratio spectra of both drugs. The same approach has been tested using the continuous wavelet transform method where a second order 2.4 of rbio and bior wavelet families were found to be optimum for measuring both drugs. Validation of the proposed methods affirmed their reliability in terms of linearity over the concentration range 1.5-30 µg/mL and 1.5-36 µg/mL for abacavir and lamivudine, respectively, precision (RSD < 2 %), and accuracy with mean recoveries ranging between 98 % and 102 %. Additionally, these spectrophotometric methodologies were applied to real pharmaceutical preparations and yielded results congruent with a prior chromatographic method. Most prominently, the proposed methods stood out for their greenness and sustainability with 97 points as evaluated by the analytical eco-scale method and a score value of 0.79 as analyzed by AGREE method, thereby making them suitable for resource-limited settings and highlighting the potential for broader application of green analytical methods in pharmaceutical analysis.

Harmaline and harmine are naturally occurring closely related ß-carboline alkaloids found in Peganum and Banisteriopsis plants. They have historical significance in traditional practices due to their potential psychoactive and therapeutic properties. Herein, a highly sensitive spectrofluorometric method was developed for the quantifying of harmaline and harmine in diverse matrices, including pure forms, seed samples, and spiked plasma. The procedures lie in addressing the challenge of overlapping fluorescence spectra exhibited by harmaline and harmine through the incorporation of hydroxypropyl-ß-cyclodextrin, altering their chemical properties and fluorescence characteristics. Synchronous fluorescence measurements coupled with first derivative mathematical technique make it possible to distinguish between the harmaline and harmine at 419 and 456 nm, respectively. The method effectiveness is demonstrated through spectral analysis, optimization of the measurement conditions, adopting validation parameters and application to the pure form, seed samples and spiked human plasma. This methodology facilitates accurate determination of these alkaloids over the concentration range of 10â200 ng/mL. Thus, the developed approach provides a robust mean for the precise determination of harmaline and harmine, contributing to analytical chemistry's ongoing efforts to address complex challenges in quantification across diverse matrices.

Autism spectrum disorder is a significant concern worldwide, particularly in Middle Eastern countries. Aripiprazole, a psychiatric medicine that works as a partial agonist at D2 receptors, is often used for autism-related behavior issues in children. Monitoring the therapy of aripiprazole could enhance the safety and effectiveness of treatment for autistic individuals. The purpose of this study was to develop a highly sensitive and environmentally friendly method for analysis of aripiprazole in plasma matrix. To achieve this, water-soluble N-carbon quantum dots were produced from a natural green precursor, guava fruit, and used in fluorescence quenching spectroscopy to determine the presence of aripiprazole. The synthesized dots were analyzed and characterized using transmission electron microscopy and Fourier transform infrared spectroscopy, and they showed a strong fluorescence emission peak at 475 nm. The proposed method was validated according to ICH M10 guidelines and was shown to be highly sensitive, allowing for nanoscale determination of aripiprazole in plasma matrix. Additionally, the method was compared to a previously reported spectrophotometric method, and it was found to be more sensitive and consistent with the principles of green analytical chemistry.

INTRODUCTION: The Ministry of Health in Saudi Arabia has announced a plan to eradicate hepatitis C virus (HCV) infection. This study sought to evaluate the knowledge levels and testing rate among the general population of Saudi Arabia. METHODS: A cross-sectional study was conducted using data collected from an online, self-administered survey. Multivariable analysis was conducted using multiple binary logistic regression models to identify factors associated with low knowledge levels as well as predictors of HCV testing. RESULTS: A total of 689 participants completed the survey. While most participants (88%) have heard of HCV infection, less than half (47.3%) understood that HCV is curable with medications. More than half of the participants (53.7%) have low knowledge about HCV infection. Testing for HCV was reported by 123 respondents (17.8%), and the odds of testing for HCV were significantly lower among residents of the Makkah region (OR = 0.59 [95% CI: 0.36-0.97]) and those with low knowledge level (OR = 0.47 [95% CI: 0.29-0.74]). HCV diagnosis was reported by nine respondents (1.3%), of whom only four reported receiving treatment (44%). CONCLUSIONS: Our study indicates inadequate knowledge levels and relatively low testing rate. These findings underscore the need for national awareness campaigns and more effective strategies for HCV screening.

Research on the use of biodegradable polymers for drug delivery has been ongoing since they were first used as bioresorbable surgical devices in the 1980s. For tissue engineering and drug delivery, biodegradable polymer poly-lactic-co-glycolic acid (PLGA) has shown enormous promise among all biomaterials. PLGA are a family of FDA-approved biodegradable polymers that are physically strong and highly biocompatible and have been extensively studied as delivery vehicles of drugs, proteins, and macromolecules such as DNA and RNA. PLGA has a wide range of erosion times and mechanical properties that can be modified. Many innovative platforms have been widely studied and created for the development of methods for the controlled delivery of PLGA. In this paper, the various manufacturing processes and characteristics that impact their breakdown and drug release are explored in depth. Besides different PLGA-based nanoparticles, preclinical and clinical applications for different diseases and the PLGA platform types and their scale-up issues will be discussed.
RESUMEN
BACKGROUND: The Makkah region is the most populated region in Saudi Arabia. Studying medication adherence levels may help to improve general health outcomes and decrease overall health care expenditures. METHODS: We used the ARMS scale to assess medication adherence. Bivariable analysis of medication non-adherence was performed. Simple and multiple logistic regression models were built to identify factors associated with medication non-adherence. RESULTS: Participants from the Makkah region were more than two times more likely to be non-adherent to their medications compared to other regions (adjusted OR = 2.58, 95% CI: 1.49-4.46). Patients who dispensed their prescriptions at their own expense were two times more likely to be non-adherents (adjusted OR = 2.36, 95% CI: 1.11-4.98). Patients who had a monthly income ≤6000 SR were almost two times more likely to be non-adherents (unadjusted OR = 1.73, 95% CI: 1.05-2.84). CONCLUSION: Medication adherence is one of the most important factors to help managing the disease. We found that Makkah chronic patients are more likely to be non-adherent with their medications compared to other regions' patients. Moreover, we found that lower monthly incomes and paying for medications out-of-pocket were significant predictors of medication non-adherence.
RESUMEN
Background: Little is known regarding the safety of direct-acting antivirals (DAA), even though they are widely used. This study aims to evaluate the adverse events of DAA using post-market data. Methods: FDA Adverse Events Reporting System (FAERS) data from January 2019 through December 2019 were analyzed. FERAS reports in which the suspected drug contained the DAA drugs were extracted and included in the analysis. Univariable and bivariable analyses were performed in this study. Results: Most of the reported side effects were non-serious (62%). The number of times the drug was reported as ineffective was significantly higher while using Harvoni vs. Mavyret (32.14% vs. 1.05%) (p-value < 0.0001). On the other hand, hospitalization was significantly more reported while using Mavyret compared to Harvoni (52.02% vs. 22.45%) (p-value < 0.0001). Liver cancer was significantly more reported while using Harvoni vs. Mavyret (7.65% vs. 1.20%) (p-value < 0.0001). No significant difference in death cases was reported while using both drugs. Conclusion: Depending on the FDA Adverse Events Reporting System (FAERS) database, most of the non-serious adverse effects were headache and fatigue. There was no significant difference in cases of death reported while using both drugs. Liver cancer was more reported while using Harvoni. Hospitalization was more reported while using Mavyret.
RESUMEN
Anabolic androgenic steroids (AASs) are synthetic analogs of testosterone that can affect the immune system. Bodybuilders and sportsmen are at risk of abusing AASs. The aim of this study was to investigate the association between AASs use and coronavirus disease (COVID-19). This cross-sectional study included adults aged 18 years and above. Between 16 April and 23 June 2021, gym-attending participants completed an online survey. Multivariable analysis was performed using multiple logistic regression to identify factors associated with COVID-19 diagnosis and severity. Current use of AASs was reported in 7.5% of the 520 study participants. Approximately 20% of the study participants reported that they had contracted COVID-19, approximately half of whom reported moderate to severe disease. Contracting COVID-19 was reported more frequently by current users than by non-current users (35.90% vs. 18.92%, p = 0.011). Multivariable analysis revealed that contracting COVID-19 was nearly five times more likely among current users of AASs than among non-current users (OR = 4.89, 95% CI: 1.69-14.13). Current use of AASs was also associated with greater odds of moderate to severe COVID-19 disease (OR = 3.71, 95% CI: 1.04-13.21). Our findings suggest that the use of AASs could be an underlying risk factor for COVID-19 severity.
RESUMEN
Background: Parkinson's disease (PD) is associated with progressive neuronal damage and dysfunction. Oxidative stress helps to regulate neurodegenerative and neuronal dysfunction. Natural compounds could attenuate oxidative stress in a variety of neurological disorders. B. juncea is a rich source of antioxidants. The present study aimed to evaluate the therapeutic potential of B. juncea leaves for the treatment of PD by applying behavioral, in vivo and in silico studies. For in vivo studies rats were divided into six groups (n = 6). Group-I served as normal control (vehicle control). Group-II was disease control (haloperidol 1 mg/kg). Group-III was kept as a standard group (L-Dopa 100 mg/kg + carbidopa 25 mg/kg). Groups (IV-VI) were the treatment groups, receiving extract at 200-, 400- and 600 mg/kg doses respectively, for 21 days orally. Results: In vivo study results showed that the extract was found to improve muscles strength, motor coordination, and balance in PD. These behavioral outcomes were consistent with the recovery of endogenous antioxidant defence in biochemical analysis which was further corroborated with histopathological ameliorations. Dopamine levels increased and monoamine oxidase B (MAO-B) levels decreased dose-dependently in the brain during the study. Herein, we performed molecular docking analysis of the proposed extracted phytochemicals has explained that four putative phytochemicals (sinapic acid, rutin, ferulic acid, and caffeic acid) have presented very good results in terms of protein-ligand binding interactions as well as absorption, distribution, metabolism, excretion & toxicity (ADMET) profile estimations. Conclusion: The undertaken study concluded the anti-Parkinson activity of B. juncea and further suggests developments on its isolated compounds in PD therapeutics.

(1) Background: Many factors may play a role in deciding to opt for pharmacy as a major. However, no previous studies have been conducted in Saudi Arabia to explore these factors. This study aims to identify the potential factors that prompted students to join the pharmacy program. (2) Methods: A cross-sectional questionnaire was distributed among undergraduate pharmacy students in Saudi Arabia, addressing areas such as reasons that encourage them to choose pharmacy as a major, and students' socio-demographic characteristics. Descriptive statistics were used to describe the study variables, and a simple logistic regression analysis was performed to identify the potential factors. (3) Results: A total of 491 students completed the questionnaire. Around 40% of them had chosen to study pharmacy as their first choice. Only gender, current GPA, and reasons related to the pharmacy field were found to have a statistically significant association with students selecting pharmacy as their first choice. (4) Conclusions: This study shows that pharmacy students have a future-oriented outlook and selected pharmacy as their first choice because it will develop them professionally, financially, and intellectually. Educating high school students about the characteristic of pharmacy would help attract more talented students to the pharmacy carrier.
RESUMEN
Allium sativum L., also known as garlic, is a perennial plant widely used as a spice and also considered a medicinal herb since antiquity. The aim of this study was to determine by gas chromatography-mass spectrometry (GC-MS) the chemical profile fingerprint of the essential oil (EO) of one accession of Peruvian A. sativum (garlic), to evaluate its antioxidant activity and an in- silico study on NADPH oxidase activity of the volatile phytoconstituents. The antioxidant activity was tested using DPPH and ß-carotene assays. An in-silico study was carried out on NADPH oxidase (PDB ID: 2CDU), as was ADMET prediction. The results indicated that diallyl trisulfide (44.21%) is the major component of the EO, followed by diallyl disulfide (22.08%), allyl methyl trisulfide (9.72%), 2-vinyl-4H-1,3-dithiine (4.78%), and α-bisabolol (3.32%). Furthermore, the EO showed antioxidant activity against DPPH radical (IC50 = 124.60 ± 2.3 µg/mL) and ß-carotene bleaching (IC50 = 328.51 ± 2.0). The best docking score on NADPH oxidase corresponds to α-bisabolol (ΔG = -10.62 kcal/mol), followed by 5-methyl-1,2,3,4-tetrathiane (ΔG = -9.33 kcal/mol). Additionally, the volatile components could be linked to the observed antioxidant activity, leading to potential inhibitors of NADPH oxidase.
RESUMEN
BACKGROUND: The novel coronavirus disease (COVID-19) has affected hundreds of thousands of people across more than 200 countries. As the pandemic continues, the health agencies, worldwide, are recommending strict preventive practices to avert its transmission at community scale. We sought to predict the behavior of the Saudi population for adopting community preventive practices during the COVID-19 pandemic. METHODS: An online questionnaire consisting of 22 items pertaining to the Health Belief Model constructs was used to measure the perceived susceptibility and perceived severity of contracting COVID-19, along with the perceived benefits and perceived barriers to follow the Ministry of Health's recommendations. The outcome was assessed by their readiness to be compliant with the community protective measures. Data were analyzed using STATA at significance level of 0.05. RESULTS: A total of 900 individuals received the online survey link, of which 688 (response rate: 76.4%) respondents consented to participate in the study. The mean age of the respondents was 31.39 (SD = 8.94). Positive associations were observed between perceived susceptibility (Beta: 0.24; p value < 0.001), perceived severity (Beta: 0.16; p value < 0.001), perceived benefits (Beta: 0.41; p value < 0.001), cue to action (Beta: 2.61; p value < 0.001) and the participation in community preventive practices during the pandemic of the COVID-19. CONCLUSIONS: Health belief model's constructs of perceived susceptibility, severity, benefits and cue to action can be adopted to help strengthen COVID-19 limiting behaviors and prevention programs which can delivered through community pharmacies in Saudi Arabia as well as around the world.
RESUMEN
Himatanthus sucuuba, also known as "Bellaco caspi", is a medicinal plant whose latex, stem bark, and leaves possess phenolic acids, lupeol, ß-dihydro-plumbericinic acid, plumericin, and plumeride, among other components. Some of these have been linked to such biological activities as antiulcer, anti-inflammatory, and wound healing. The aim of this study was to determine the phytochemical compounds of H. sucuuba latex, as well as its in vitro cytotoxicity and wound healing effect in mice. Latex was collected in the province of Iquitos, Peru. Phytochemical analysis was carried out with UPLC-ESI-MS/MS. The cytotoxicity was evaluated on two colon tumor cell lines (SW480 and SW620) and non-malignant cells (human keratinocytes, HaCaT, and Chinese hamster ovary, CHO-K1). The mice were distributed into two groups, as follows: Group I-control (n = 10; without treatment); II-(n = 10) H. sucuuba latex; wounds were induced with a scalpel in the dorsal-cervical area and treatments were applied topically twice a day on the incision for 10 days. Molecular docking was carried out on the glycogen synthase kinase 3ß protein. Twenty-four chemical compounds were determined, mainly flavonoid-type compounds. Latex did not have a cytotoxic effect on tumor cells with IC50 values of more than 500 µg/mL. The latex had a regenerative effect on wounds in mice. Acacetin-7-O-neohesperidoside had the best docking score of -9.9 kcal/mol. In conclusion, H. sucuuba latex had a wound healing effect in mice, as confirmed by histological study. However, a non-cytotoxic effect was observed on colon tumor cells SW480 and SW620.
RESUMEN
In the first few months of the pandemic, Makkah region reported the highest number of COVID-19 cases among all regions in Saudi Arabia. More than 80% of these reported cases were non-Saudi residents. In this study, we evaluated the perceived threat from and psychological impact of COVID-19 among non-Saudi residents of Makkah region. This was a cross-sectional analysis of data collected using a standardized self-report questionnaire. A total of 292 expatriates were included in the study, the majority of whom were non-Arabic speakers. The prevalence of self-reported depression was nearly 40%, anxiety was 32%, and stress was 43%. The findings indicated variability in the prevalence of psychological symptoms among expatriates from different ethnic backgrounds. Additionally, work environment and perceived threat were strong predictors of psychological disorders. This suggested that the perceived threat from and psychological burden of COVID-19 among non-Saudis in Makkah region is substantial. Future research should investigate the reasons behind these variations in the psychological impact of the pandemic among different ethnic groups.

OBJECTIVES: Pharmacoeconomics and health economics in general is a new field that is still developing and emerging, not only in Saudi Arabia but all over the world. The objective of this study is to collect all published cost-effectiveness analysis (CEA) studies conducted based on Saudi settings and to evaluate their reporting quality. METHODS: We used PRISMA guidelines to search for all English-language CEAs conducted in Saudi Arabia in 3 databases: Medline, Embase, and Scopus. Keywords used in the search were: cost-effectiveness, cost-benefit, cost-utility, economic evaluation, Saudi Arabia. The data extracted were analyzed to assess reporting quality based on Consolidated Health Economic Evaluation Reporting Guidelines (CHEERS) and the second panel recommendations. RESULTS: The 3 databases yielded 859 articles after removing duplicates. Only 7 articles included as final results following PRISMA guidelines. These 7 studies were published between 2015 and 2020. The CEA studies varied in their reporting quality; however, there were common missing required items among all of them, such as justifying choosing of a specific model and time horizon and reporting the ethical implications of the studied interventions. CONCLUSION: Seven published CEA studies were conducted based on Saudi settings as revealed by this review. The included studies reported the more important aspects of CEA studies. However, there were missed reporting items based on the checklists we used to assess CEAs in this review. Although perfect and complete adherence to CHEERS or the second panel guidelines is a high standard, future CEAs should adhere to such standards. Transparency and good reporting are cornerstones in CEAs, and future CEAs should report their methods, findings, and results in a more transparent and efficient way.
