Saudi Pharm J 2024; 32:101968. [PMID: 38352238 PMCID: PMC10862413 DOI: 10.1016/j.jsps.2024.101968] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/16/2023] [Accepted: 01/25/2024] [Indexed: 02/16/2024] Open
Abstract
Asthma is a chronic disease affecting people of all ages. Asthma medications are associated with adverse effects restricting their long-term usage, demanding newer alternative therapies. This study aimed to investigate the anti-asthmatic properties of Ruta graveolens extract and its prepared nano-cubosomal dispersion (Ruta-ND). Firstly, the R. graveolens methanolic extract exhibited higher anti-inflammatory activity on Lipopolysaccharide (LPS)-activated BEAS-2B cells. To ensure best bioavailability and hence best cellular uptake, R. graveolens extract was loaded in nano-cubosomal dispersion (ND). Then, the anti-asthmatic effects of Ruta extract and ND were simultaneously evaluated in rats' model with ovalbumin-induced allergic asthma. R. graveolens extract and Ruta-ND subsided asthma score and improved lung function by restoring FEV1/FVC ratio to the expected values in control rats. Also, it showed strong antioxidant and anti-inflammatory activities manifested by lowering levels of malondialdehyde (MDA), IL-4, IL-7, TGF-β, and Ig-E, and increasing levels of superoxide dismutase (SOD) and INF-γ in bronchoalveolar lavage fluid. Our research findings also indicate autophagy induction and apoptosis inhibition by Ruta extract and Ruta-ND. Finally, the HPLC MS/MS phytochemical profiling of R. graveolens extract evident production of various alkaloids, flavonoids, coumarins, and other phenolics with reported pharmacological properties corresponding to/emphasize our study findings. In conclusion, R. graveolens exhibited promise in managing Ova-induced allergic asthma and could be developed as an alternative anti-allergic asthma drug.

Taste Masking of Promethazine Hydrochloride Using l-Arginine Polyamide-Based Nanocapsules. Molecules 2023; 28:molecules28020748. [PMID: 36677806 PMCID: PMC9865149 DOI: 10.3390/molecules28020748] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/09/2022] [Revised: 01/09/2023] [Accepted: 01/09/2023] [Indexed: 01/15/2023] Open
Abstract
Promethazine hydrochloride (PMZ), a potent H1-histamine blocker widely used to prevent motion sickness, dizziness, nausea, and vomiting, has a bitter taste. In the present study, taste masked PMZ nanocapsules (NCs) were prepared using an interfacial polycondensation technique. A one-step approach was used to expedite the synthesis of NCs made from a biocompatible and biodegradable polyamide based on l-arginine. The produced NCs had an average particle size of 193.63 ± 39.1 nm and a zeta potential of −31.7 ± 1.25 mV, indicating their stability. The NCs were characterized using differential scanning calorimetric analysis and X-ray diffraction, as well as transmission electron microscopy that demonstrated the formation of the NCs and the incorporation of PMZ within the polymer. The in vitro release study of the PMZ-loaded NCs displayed a 0.91 ± 0.02% release of PMZ after 10 min using artificial saliva as the dissolution media, indicating excellent taste masked particles. The in vivo study using mice revealed that the amount of fluid consumed by the PMZ-NCs group was significantly higher than that consumed by the free PMZ group (p < 0.05). This study confirmed that NCs using polyamides based on l-arginine and interfacial polycondensation can serve as a good platform for the effective taste masking of bitter actives.

Abstract
Thymoquinone (TQ), the main active constituent of Nigella sativa, has demonstrated broad-spectrum antimicrobial, antioxidant, and anti-inflammatory effects, which suggest its potential use in secondary infections caused by COVID-19. However, clinical deployment has been hindered due to its limited aqueous solubility and poor bioavailability. Therefore, a targeted delivery system to the lungs using nanotechnology is needed to overcome limitations encountered with TQ. In this project, a novel TQ-loaded poly(ester amide) based on L-arginine nanoparticles was prepared using the interfacial polycondensation method for a dry powder inhaler targeting delivery of TQ to the lungs. The nanoparticles were characterized by FTIR and NMR to confirm the structure. Transmission electron microscopy and Zetasizer results confirmed the particle diameter of 52 nm. The high-dose formulation showed the entrapment efficiency and loading capacity values of TQ to be 99.77% and 35.56%, respectively. An XRD study proved that TQ did not change its crystallinity, which was further confirmed by the DSC study. Optimized nanoparticles were evaluated for their in vitro aerodynamic performance, which demonstrated an effective delivery of 22.7–23.7% of the nominal dose into the lower parts of the lungs. The high drug-targeting potential and efficiency demonstrates the significant role of the TQ nanoparticles for potential application in COVID-19 and other respiratory conditions.

[PMID: 35527831 PMCID: PMC9068573 DOI: 10.1016/j.jsps.2022.02.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/01/2021] [Accepted: 02/07/2022] [Indexed: 11/27/2022] Open
Abstract
Background Medication error is a preventable adverse effect of medical care, whether or not it is evident or harmful to the patient. Disclosure of medication errors and improvement of patient safety are inexorably related, and they provide one of the strongest reasons to report and disclose errors, including near misses in which no harm comes to the patient. This study aimed to identify medication errors at the southern province of Saudi Arabia. Methods A cross-sectional retrospective study was conducted by reviewing all medical records in the King Khaled Hospital in Najran, Saudi Arabia. Medication errors related information were extracted from the electronic medical system for the duration between 2018 and 2020. Results During the study period of 2018 to 2020, a total of 4860 medication errors were identified. More than half of the reported medication errors (66.9%) were linked to ordering, prescribing, or transcribing medications. The most commonly reported medication errors connected to ordering/prescribing/transcribing were inappropriate dosage, dosage units, and therapeutic duplication of medication. The most commonly reported medication errors linked to administration were missing documentation during administration, not performing independent double-checks during the administration of high alert medications, and the administration of look-alike sound-alike (LASA) medications. The intensive care unit (ICU), female medical ward, and male medical ward were the most commonly reported locations for medication errors. Pharmacists detected more than half of the reported medication errors. Physicians were found to be responsible for 66.0% of reported medication errors, followed by nurses. Conclusion Medication errors are common in hospital settings in Saudi Arabia's southern provinces. Efforts should be made to improve drug ordering, prescribing, and transcription in hospital settings. To guarantee optimum practices, the entire medical team should take responsibility for the patient's optimal medication administration.

Abstract
Chemotherapeutic-related toxicity exacerbates the increasing death rate among cancer patients, necessitating greater efforts to find a speedy solution. An in vivo assessment of the protective effect of the C. macrocarpa leaves polar fraction of hydromethanolic extract against doxorubicin (Dox)-induced neurotoxicity was performed. Intriguingly, this fraction ameliorated Dox-induced cognitive dysfunction; reduced serum ROS and brain TNF-α levels, upregulated the brain nerve growth factor (NGF) levels, markedly reduced caspase-3 immunoexpression, and restored the histological architecture of the brain hippocampus. The in vivo study results were corroborated with a UPLC-ESI-MS/MS profiling that revealed the presence of a high percentage of the plant polyphenolics. Molecular modeling of several identified molecules in this fraction demonstrated a strong binding affinity of flavan-3-ol derivatives with TACE enzymes, in agreement with the experimental in vivo neuroprotective activity. In conclusion, the C. macrocarpa leaves polar fraction possesses neuroprotective activity that could have a promising role in ameliorating chemotherapeutic-induced side effects.

Abstract
Hydrogels being a drug delivery system has great significance particularly for topical application in cutaneous open wound. Its specific physicochemical properties such as non-adhesiveness, moisture retention, exudate absorption, and gas permeability make them ideal as a drug delivery vehicle for wound healing application. Further, curcumin (a natural bioactive) was selected as a therapeutic agent to incorporate into the hydrogel system to design and develop nanogel pharmaceutical products for wound healing. Although, curcumin possesses remarkable anti-inflammatory, antioxidant, and anti-infective activity along with hastening the healing process by acting over the different stages of the wound healing process, but its poor biopharmaceutical (low aqueous solubility and skin penetrability) attributes hamper their therapeutic efficacy for skin applications. The current investigation aimed to develop the curcumin-loaded nanogel system and evaluated to check the improvement in the therapeutic efficacy of curcumin through a nanomedicine-based approach for wound healing activity in Wistar rats. The curcumin was enclosed inside the nanoemulsion system prepared through a high-energy ultrasonic emulsification technique at a minimum concentration of surfactant required to nanoemulsify the curcumin-loaded oil system (Labrafac PG) having droplet size 56.25 ± 0.69 nm with polydispersity index 0.05 ± 0.01 and negatively surface charge with zeta potential −20.26 ± 0.65 mV. It was observed that the impact of Smix (surfactant/co-surfactant mixture) ratio on droplet size of generated nanoemulsion is more pronounced at lower Smix concentration (25%) compared to the higher Smix concentration (30%). The optimized curcumin-loaded nanoemulsion was incorporated into a 0.5% Carbopol® 940 hydrogel system for topical application. The developed curcumin nanoemulgel exhibited thixotropic rheological behavior and a significant (p < 0.05) increase in skin penetrability characteristics compared to curcumin dispersed in conventional hydrogel system. The in vivo wound healing efficacy study and histological examination of healed tissue specimen further signify the role of the nanomedicine-based approach to improve the biopharmaceutical attributes of curcumin.

Abstract
AIMS This study aimed to evaluate the effectiveness of an educational intervention in improving the patient medication reconciliation process. METHOD This was a cross-sectional study that was conducted at St. Jude hospital, California (CA), United States. An educational intervention was provided to the healthcare team working in the emergency department (ED) to explore its effectiveness in improving their patient medication reconciliation practices. A survey was administered to explore the healthcare staff's views on where responsibility lay in their team concerning the fulfilment of appropriate medication reconciliation procedures. Additionally, we identified the barriers facing the completion of appropriate medication reconciliation using open-ended question provided to healthcare staff at the hospital. RESULTS In the pre-intervention phase, the percentage of patients who received medication reconciliation was statistically significantly higher during the day shift (71.0% compared with 51.3%). In the postintervention phase, the percentage of patients who received medication reconciliation was statistically significantly higher during the night shift (96.7% compared with 75.8%). Overall, the percentage of patients who received medication reconciliation was statistically significantly higher in the postintervention group (81.3%) compared with the pre-intervention group (64.7%) (P < .001). CONCLUSION Educational intervention is an effective tool in improving medication reconciliation practices in inpatient settings. The process of medication reconciliation should be conducted based on shared responsibility between healthcare providers and aimed at reducing medication errors and improving patient safety.

Abstract
This study aims to evaluate the anti-Leishmania major and the lung adenocarcinoma (A549) cytotoxicity of Withania somnifera root and fruit. The total extracts were obtained by homogenisation in aqueous MeOH, and the sub-extracts [n-hexane, ethyl acetate (EtOAc), n-butanol (n-BuOH), and methanol (MeOH)] were obtained by flash chromatography. The activity evaluation showed that n-BuOH sub-extracts from root and fruit exhibited noticeable antileishmanial promastigote properties. The n-hexane and EtOAc sub-extracts from both organs, and the MeOH sub-extract from the fruit exerted mild to moderate effects on the promastigotes. In-vitro growth-inhibitory test results on axenic amastigote and cytotoxicity testing on macrophages (RAW264.7), the parasite-host at the amastigote stage, revealed that the activity was mainly concentrated in the root EtOAc and n-BuOH sub-extracts and to a lesser extent the fruit MeOH and EtOAc, and the root n-hexane sub-extracts. Only the roots' EtOAc and n-BuOH sub-extracts demonstrated low cytotoxicity on the A549 cell line.

Abstract
Children have often been treated as small adults in relation to drug formulation, but research has now shown this not to be the case. Therefore, there is a push from regulatory bodies to provide drug formulations specifically tailored towards the needs of this fragmented population. Orally dissolving films (ODFs) have been identified as an emerging opportunity, to bridge this gap. Therefore, the aim of this study was to prepare ODFs containing topiramate, an antiepileptic drug, using solvent casting method as a potential alternative to oral tablets/powders for paediatrics. For this purpose, a Design of Experiment (DoE) was employed to optimise formulation parameters. 24 formulations were prepared by changing the polymer type (HPMC, Guar-Gum or PEO), concentration (0.4%-1.2%w/v); plasticizer type (glycerol\sorbitol) and concentration (0.1–0.3%w/v). Disintegration time, content-uniformity, film quality and thickness uniformity were the responses. Surface and molecular profiling were conducted on the optimal formulation (N4). TGA and XRD results demonstrated the stability of materials upon production into films, while the SEM images showed smooth films that proved to be resilient due to good mechanical properties. HPMC-glycerine based ODFs are presented as an effective dosage form to enhance the ease of administration and patient compliance of topiramate, specifically for paediatric patients.

Abstract
Liquisolid compact is a novel dosage form in which a liquid medication (liquid drug, drug solution/dispersion in non-volatile solvent/solvent system) is converted to a dry, free flowing powder and compressed. Objective of the study was to elucidate the effect of carrier material on release characteristics of clopidogrel from liquisolid compacts. Different formulations of liquisolid compacts were developed using microcrystalline cellulose, starch maize, polyvinyl pyrollidone and hydroxypropyl methylcellulose as carrier material in three concentrations (40, 30 and 20%, w/w). Liquid vehicle was selected on the basis of solubility of clopidogrel. Colloidal silicondioxide was used as coating material and ratio of carrier to coating material was kept 10. A control formulation comprised of microcrystalline cellulose (diluents), tabletose-80 (diluents), primojel (disintegrant) and magnesium stearate (lubricant) was prepared by direct compression technique and was used for comparison. All the formulations were evaluated at pre and post compression level. Acid solubility profile showed higher solubility in HCl buffer pH2 (296.89±3.49 μg/mL). Mixture of propylene glycol and water (2:1, v/v) was selected as liquid vehicle. Drug content was in the range of 99–101% of the claimed quantity. All the formulations showed better mechanical strength and their friability was within the official limits (<1%). Microcrystalline cellulose and starch maize resulted in faster drug release while polyvinyl pyrollidone and HPMC resulted in sustaining drug release by gel formation. It is concluded from results that both fast release and sustained release of clopidogrel can be achieved by proper selection of carrier material.

Abstract
Retinoblastoma is the most frequent primary intraocular tumour in childhood. Early detection of retinoblastoma is the key to successful management with a higher chance of survival. This study aims to assess the knowledge of the general population and healthcare providers about retinoblastoma in term of presentation, risk factors, timing for diagnosis, and complications. A cross-sectional study using an online survey was conducted in three Arab countries (Jordan, Saudi Arabia, and Iraq) between 28 August and 16 September 2020. The questionnaire tool was constructed based on an extensive literature review to explore the study's aim and objectives. Logistic regression was used to identify predictors of better knowledge about retinoblastoma. A total of 3676 participants were involved in the study (Jordan = 2654, Saudi Arabia = 604, and Iraq = 418). The average retinoblastoma knowledge score for the whole study population was 6.25 (SD = 4.12) out of 21, representing 29.8% (out of the maximum possible total score). Participants aged above 50 years old, married individuals, those with a secondary education level, those who work as professionals in industry, those who have more than four children, and those who reported that they were not in direct contact with a large number of children were less likely to be knowledgeable about retinoblastoma presentation, risk factors, the timing for diagnosis, and complications (P < .05). Early detection is the cornerstone for decreasing morbidity and mortality among children with retinoblastoma. However, the awareness and knowledge about retinoblastoma are very limited in our study population. Efforts should be directed at increasing awareness of both the general population and healthcare providers regarding retinoblastoma. Policymakers are responsible for improving knowledge and awareness about retinoblastoma to facilitate early detection of the disease by conducting awareness campaigns in addition to improve screening skills of healthcare providers and providing them with proper screening and diagnostic tools.

Such an unusual situation may have an undesirable impact on the mental health of individuals which, in turn, may influence their outcomes. This study aimed to explore the influence of the COVID-19 pandemic on the psychological disposition of residents of the Kingdom of Saudi Arabia. METHODS A cross-sectional study using an online survey was conducted in Saudi Arabia between 27 March and 27 April 2020. The Patient Health Questionnaire (PHQ-9) and Generalised Anxiety Disorder-7 (GAD-7) were used to assess depression and anxiety. Logistic regression analysis was used to identify predictors of these. RESULTS A total of 2081 individuals participated in the study. The prevalence of depression and anxiety among the study participants was 9.4% and 7.3% respectively. Non-Saudi residents, individuals aged 50 years and above, divorced people, retired people, university students and those with an income between 2000 and 10 000 SR were at higher risk of developing depression. Saudi individuals, married people, the unemployed and those with a high income (>10 000 RS) were at higher risk of developing anxiety. CONCLUSION We found that there is a wide range of Saudi residents who are at higher risk of developing mental illness during the current COVID-19 pandemic. Policymakers and mental healthcare providers are advised to provide continuous monitoring of the psychological consequences during this pandemic and provide the required health support.

Clinical and Therapeutic Characteristics of Cancer Patients in the Southern Region of Saudi Arabia: A Cross-Sectional Study. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:ijerph18126654. [PMID: 34205637 PMCID: PMC8296400 DOI: 10.3390/ijerph18126654] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/16/2021] [Revised: 06/15/2021] [Accepted: 06/16/2021] [Indexed: 12/03/2022]
Abstract
Aims: Due to the continuous changes in modern lifestyle and the need to explore the effect of these changes on the risk of developing cancer, ongoing research on the epidemiology and characteristics of cancer patients is requested. This study explored the epidemiology of cancer, its characteristics, treatment patterns, and risk factors in the southern region of Saudi Arabia. Methods: A retrospective cross-sectional study was conducted using cancer patients’ medical records at Asir Central Hospital in the southern region of Saudi Arabia. Active patients’ records were extracted between January 2013 and December 2019. Results: A total of 2038 patients were identified during the study period, with a mean age of 60.9 (SD: 19.0) years. The patients had survived with their cancer for a median duration of 4 years (IQR: 2–6). Around 4.6% of the patients required ICU admission with a median period of 9 days (IQR: 5–14.75). The death rate during the study period was 10.9%. Around 20.8% of the cases were metastatic, of which 77.8% were at stage four of metastasis, and 19.7% of the patients were receiving chemotherapy for their disease. The most common types of cancer were malignant neoplasms of digestive organs, comprising 40.8% of the sample. Older age (60 years and above) and using specific chronic disease medications were predictors associated with a higher risk of death due to cancer (p < 0.05). Smoking history, using specific chronic disease medications, and having previous surgery were predictors associated with a higher risk of ICU admission (p < 0.05). Conclusion: Breast, colon, and liver cancers were the most prevalent in the southern region of Saudi Arabia. Several modifiable cancer risk factors were identified. The results of this study should support decision-makers in the initiation of programs for key modifiable risk factors that enhance lifestyle changes and reduce cancer risks.

Formulation of sublingual promethazine hydrochloride tablets for rapid relief of motion sickness. Saudi Pharm J 2021; 29:478-486. [PMID: 34135674 PMCID: PMC8180616 DOI: 10.1016/j.jsps.2021.04.011] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/23/2020] [Accepted: 04/13/2021] [Indexed: 01/21/2023] Open
Abstract
The delivery of antihistaminic agents via the oral route is problematic, especially for elderly patients. This study aimed to develop a sublingual formulation of promethazine hydrochloride by direct compression, and to mask its intensely bitter taste. Promethazine hydrochloride (PMZ) sublingual tablets prepared by direct compression were optimized using Box-Behnken full factorial design. The effect of a taste-masking agent (Eudragit E 100, X1), superdisintegrant (crospovidone; CPV, X2) and lubricant (sodium stearyl fumarate; SSF, X3) on sublingual tablets’ attributes (responses, Y) was optimized. The prepared sublingual tablets were characterized for hardness (Y1), disintegration time (Y2), initial dissolution rate (IDR; Y3) and dissolution efficiency after 30 min (Dissolution Efficiency (DE); Y4). The obtained results showed a significant positive effect of the three independent factors on tablet hardness (P < 0.05), and the interactive effect of Eudragit E 100 and CPV on tablet hardness was significant. Disintegration time was mainly affected by Eudragit E 100 and CPV concentrations. Moreover, IDR was employed to assess the taste masking effect, lower values were obtained at higher Eudragit E 100 concentration despite it was statistically insignificant (p > 0.05). Optimized formulation that was suggested by the software was composed of: Eudragit E 100 (X1) = 2.5% w/w, CPV (X2) = 4.13% w/w, and SSF (X3) = 1.0% w/w. The observed values of the optimized formula were found to be close to the predicted optimized values. The Differential Scanning Calorimetric (DSC) studies indicated no interaction between PMZ and tablet excipients.

Investigation of Plantago ovata Husk as Pharmaceutical Excipient for Solid Dosage Form (Orodispersible Tablets). BIOMED RESEARCH INTERNATIONAL 2021; 2021:5538075. [PMID: 34235217 PMCID: PMC8219414 DOI: 10.1155/2021/5538075] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/09/2021] [Accepted: 06/08/2021] [Indexed: 11/17/2022]
Abstract
The objective of the study was to investigate the suitability of the Plantago ovata (PO) husk as a pharmaceutical excipient. Various phytoconstituents of the husk were determined according to the standard test procedures. The Plantago ovata husk was evaluated for various pharmaceutical parameters related to flow, swelling index, and compressibility index. Orodispersible tablets (ODTs) were prepared, containing different concentrations (2.5, 3, 5, 7.5, 10, and 15% w/w) of the Plantago ovata husk. Before compression, all the formulations were evaluated for their flow. Compressed ODTs were evaluated for physical characteristics (physical appearance, weight and weight variation, thickness, and moisture content), mechanical strength (crushing strength, specific crushing strength, tensile strength, and friability), disintegration behavior (disintegration time and oral disintegration time), drug content, and in vitro drug release. Phytochemical evaluation of the Plantago ovata husk confirmed the presence of various phytoconstituents like alkaloids, tannins, glycosides, saponins, flavonoids, and phenols. SEM photograph of the Plantago ovata husk showed that it has a fibrous structure, with a porous and rough surface. The Plantago ovata husk had a high swelling index (380%) which decreased by pulverization (310%). Precompression evaluation of the powder blend for all the formulations of ODTs showed good flow properties, indicating that the Plantago ovata husk improved the rheological characteristics of the powder blend. Compressed ODTs had good mechanical strength, and their friability was within the official limits (<1%). Best disintegration was observed with formulation F-6 containing 10% w/w of the Plantago ovata husk. It is concluded that the Plantago ovata husk can be used as a disintegrant in the formulation of ODTs.

Depression and Anxiety in Patients With Cancer: A Cross-Sectional Study. Front Psychol 2021; 12:585534. [PMID: 33935849 PMCID: PMC8081978 DOI: 10.3389/fpsyg.2021.585534] [Citation(s) in RCA: 65] [Impact Index Per Article: 21.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/06/2020] [Accepted: 03/11/2021] [Indexed: 11/13/2022] Open
Abstract
Objectives Depression and anxiety persist in cancer patients, creating an additional burden during treatment and making it more challenging in terms of management and control. Studies on the prevalence of depression and anxiety among cancer patients in the Middle East are limited and include many limitations such as their small sample sizes and restriction to a specific type of cancer in specific clinical settings. This study aimed to describe the prevalence and risk factors of depression and anxiety among cancer patients in the inpatient and outpatient settings. Materials and Methods A total of 1,011 patients (399 inpatients and 612 outpatients) formed the study sample. Patients’ psychological status was assessed using the Hospital Anxiety and Depression Scale (HADS), the Patient Health Questionnaire (PHQ-9), and the Generalized Anxiety Disorder 7-item (GAD-7) scale. The prevalence rate of depressive and anxious symptomatology was estimated by dividing the number of patients who exceeded the borderline score: 10 or more for each subscale of the HADS scale, 15 or more for the GAD-7 scale, and 15 or more in the PHQ-9 by the total number of the patients. Risk factors were identified using logistic regression. Results The prevalence of depressive and anxious symptomatology among all patients was 23.4% and 19.1–19.9%, respectively. Depressive symptomatology was more prevalent across patients who were hospitalized (37.1%) compared with patients in the outpatient setting (14.5%) (p < 0.001). Similarly, anxious symptomatology was more prevalent in the inpatient setting (p < 0.001). In the inpatient setting, depressive symptomatology was more prevalent among patients with bladder cancer, while severe anxious symptomatology was more prevalent across patients with lung cancer. In the outpatient setting, depressive and anxious symptomatology was more prevalent among breast and prostate cancer patients, respectively. Despite that, around 42.7% and 24.8% of the patients, respectively, reported that they feel anxious and depressed, and only 15.5% of them were using medications to manage their conditions. Conclusion Our study findings demonstrated a higher prevalence of depressive and anxious symptomatology in the inpatient setting and advanced disease stages. In addition, the underutilization of antidepressant therapy was observed. There is a need to consider mental disorders as part of the treatment protocol for cancer patients. Enhanced clinical monitoring and treatment of depression and anxiety of cancer patients are required.

The perspectives of physicians regarding antidiabetic therapy de-intensification and factors affecting their treatment choices-A cross-sectional study. Int J Clin Pract 2021; 75:e13662. [PMID: 32770843 DOI: 10.1111/ijcp.13662] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/09/2020] [Accepted: 08/06/2020] [Indexed: 02/06/2023] Open
Abstract
AIMS Comprehensive diabetes management may include treatment intensification or the administration of antidiabetic combination therapy. However, this may be associated with an increased risk of adverse events and death. The aim of this study was to understand physicians' perspectives regarding treatment de-intensification, HbA1c goals individualisation, and factors affecting their treatment choice for patients with type 2 diabetes mellitus (T2DM). METHODS A cross-sectional study was conducted in primary and secondary care units in Saudi Arabia using online questionnaire. Two previously validated questionnaires were used to understand physicians' awareness of, agreement with, and their practices of individualising HbA1c goals and antidiabetic treatment optimisation, and to assess factors affecting physicians' treatment choice when prescribing antidiabetic treatment for patients with type 2 diabetes mellitus. Study population were physicians who are treating patients with diabetes mellitus during the period between October 2017 and May 2018. RESULTS A total of 205 physicians have participated in the study. Approximately 50% of physicians had family medicine speciality (n = 98, 47.8%). The majority of physicians (n = 183, 89.3%) were familiar with the concept of HbA1c goals individualisation. However, only 66.3% of them (n = 136) reported that they apply it either always or most of the time. 58.5% (n = 120) of physicians reported that they would not initiate conversations about de-intensifying antidiabetic therapy even if their patients had a stable HbA1c values for one year. Physicians showed higher consideration to objective patient clinical data and their assessment of patient's health status, with minor consideration to patient-related factors. CONCLUSIONS Healthcare professionals should focus more on implementing contemporary practices and applying any necessary treatment de-intensification or dose adjustment. Subjective patient factors should be taken into account further, as these factors are associated with better disease management.

Attitudes of pharmacy students towards patient safety: a cross-sectional study from six developing countries. BMJ Open 2020; 10:e039459. [PMID: 33323431 PMCID: PMC7745325 DOI: 10.1136/bmjopen-2020-039459] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/15/2020] [Revised: 10/17/2020] [Accepted: 11/13/2020] [Indexed: 11/17/2022] Open
Abstract
OBJECTIVE To evaluate the attitudes of undergraduate pharmacy students towards patient safety in six developing countries. DESIGN A cross-sectional study. SETTING Participants were enrolled from the participating universities in six countries. PARTICIPANTS Undergraduate pharmacy students from the participating universities in six developing countries (Jordan, Saudi Arabia, Kuwait, Qatar, India and Indonesia) were invited to participate in the study between October 2018 and September 2019. PRIMARY OUTCOME Attitudes towards patient safety was measured using 14-item questionnaire that contained five subscales: being quality-improvement focused, internalising errors regardless of harm, value of contextual learning, acceptability of questioning more senior healthcare professionals' behaviour and attitude towards open disclosure. Multiple-linear regression analysis was used to identify predictors of positive attitudes towards patient safety. RESULTS A total of 2595 students participated in this study (1044 from Jordan, 514 from Saudi Arabia, 134 from Kuwait, 61 from Qatar, 416 from India and 429 from Indonesia). Overall, the pharmacy students reported a positive attitude towards patient safety with a mean score of 37.4 (SD=7.0) out of 56 (66.8%). The 'being quality-improvement focused' subscale had the highest score, 75.6%. The subscale with the lowest score was 'internalising errors regardless of harm', 49.2%. Female students had significantly better attitudes towards patient safety scores compared with male students (p=0.001). Being at a higher level of study and involvement in or witnessing harm to patients while practising were important predictors of negative attitudes towards patient safety (p<0.001). CONCLUSION Patient safety content should be covered comprehensively in pharmacy curricula and reinforced in each year of study. This should be more focused on students in their final year of study and who have started their training. This will ensure that the next generation of pharmacists are equipped with the requisite knowledge, core competencies and attitudes to ensure optimal patient safety when they practice.

Abstract
Purpose: To investigate the influence of two often-used excipients (starch and microcrystalline cellulose) on the physical properties of powder blends and tablets that contain mannitol as diluent.Methods: Powder and powder mixtures of three commonly used excipients (starch, mannitol and microcrystalline cellulose) were thoroughly examined using the angle of repose for flowability, particle size analyzer to determine the diameter of the particles, scanning electron microscopy (SEM) for morphological assessment, and x-ray diffraction to determine crystalline/amorphous characteristics. Tablets were prepared by direct compression technique and were evaluated for mechanical strength and disintegration behavior as part of quality control test.Results: The results showed that increase in MCC concentration of the mixture leads to significantly enhanced flowability (p < 0.05) when compared to starch. The angle of repose for mannitol/MCC powder mixture with 70 % w/w MCC was approximately 29°, indicating good flow properties of thepowder mix. Moreover, starch tablets containing MCC exhibited better mechanical strength and longer disintegration time, while, at 1:1 ratio of MCC and mannitol, tablet disintegration was faster (33.0 ± 5.2s)Conclusion: MCC (at 30 %w/w in the blend) produces optimal flow of the powder blend and superior mechanical strength,

Abstract
Objectives: Considering the transmissible nature of COVID-19 it is important to explore the trend of the epidemiology of the disease in each country and act accordingly. This study aimed to examine the trend of COVID-19 epidemiology in the Kingdom of Saudi Arabia in term of its incidence rate, recovery rate, and mortality rate. Material and Methods: We conducted an observational study using publicly available national data taken from the Saudi Ministry of Health for the period between 3 March and 7 June 2020. The number of newly confirmed cases, active cases, critical cases, percentage of cases stratified by age group [adults, children, and elderly] and gender were extracted from the reports of the Saudi Ministry of Health. Results: During the study period, the total number of confirmed cases with COVID-19 rose from one on 2 March 2020 to 101,914 on 7 June, representing an average of 1,039 new cases per day, [trend test, p < 0.000]. Despite the increase in the number of newly confirmed daily cases of COVID-19, the number of reported daily active cases started to stabilize after 2 months from the start of the pandemic in the country and the overall recovery rate was 71.4%. The mortality rate decreased by 6.4% during the study period. COVID-19 was more common among adults and males compared to other demographic groups. Conclusion: The epidemiological status of COVID-19 in the Kingdom of Saudi Arabia showing promising improvement. Males and adults accounted for the majority of COVID-19 cases in the KSA. Further studies are recommended to be conducted at the patient level to identify other patient groups who are at higher risk of getting infected with COVID-19, and for whom the best pharmacological intervention could be provided.

Abstract
BACKGROUND The emergence of COVID-19 global pandemic coupled with high transmission rate and mortality has created an unprecedented state of emergency worldwide. This global situation may have a negative impact on the psychological well-being of individuals which in turn impacts individuals' performance. This study aims to explore the prevalence of depression and anxiety among the GP, HCPs, and USs during COVID-19 outbreak, and to identify key population(s) who might need psychological intervention. METHODS A cross-sectional study using an online survey was conducted in Jordan between 22 and 28 March 2020 to explore the mental health status (depression and anxiety) of the general population, healthcare professionals, and university students during the COVID-19 outbreak. The Patient Health Questionnaire (PHQ-9) and Generalized Anxiety Disorder-7 (GAD-7) were used to assess depression and anxiety among the study participants. Logistic regression analysis was used to identify predictors of depression and anxiety. RESULTS The prevalence of depression and anxiety among the entire study participants was 23.8% and 13.1%, respectively. Anxiety was most prevalent across university students 21.5%, followed by healthcare professionals 11.3%, and general population 8.8%. Females among healthcare professionals and university students, divorced healthcare professionals, pulmonologists, and university students with history of chronic disease were at higher risk of developing depression. Females, divorced participants among the general population, and university students with history of chronic disease and those with high income (≥1,500 JD) were at higher risk of developing anxiety. CONCLUSIONS During outbreaks, individuals are put under extreme stressful condition resulting in higher risk of developing anxiety and depression particularly for students and healthcare professionals. Policymakers and mental healthcare providers are advised to provide further mental support to these vulnerable groups during this pandemic.
