The dynamin-related protein Vps1 and the peroxisomal membrane protein Pex27 function together during peroxisome fission.

Dynamin-related proteins (Drps) mediate a variety of membrane remodelling processes. The Saccharomyces cerevisiae Drp, Vps1, is required for endocytosis, endosomal sorting, vacuole fusion, and peroxisome fission and breakdown. How Drps, and in particular Vps1, can function at so many different subcellular locations is of interest to our understanding of cellular organisation. We found that the peroxisomal membrane protein Pex27 is specifically required for Vps1-dependent peroxisome fission in proliferating cells but is not required for Dnm1-dependent peroxisome fission. Pex27 accumulates in constricted regions of peroxisomes and affects peroxisome geometry upon overexpression. Moreover, Pex27 physically interacts with Vps1 in vivo and is required for the accumulation of a GTPase-defective Vps1 mutant (K42A) on peroxisomes. During nitrogen starvation, a condition that halts cell division and induces peroxisome breakdown, Vps1 associates with the pexophagophore. Pex27 is neither required for Vps1 recruitment to the pexophagophore nor for pexophagy. Our study identifies Pex27 as a Vps1-specific partner for the maintenance of peroxisome number in proliferating yeast cells.

Endoscopic repair of nasal septal perforation with anterior ethmoidal artery flap using tunnel technique.

PURPOSE: Septal perforations (SPs) present a distinct challenge. There are many described surgical approaches with variable success rates. The goal of this study is to describe a new technique in repairing SP. METHODS: A case series of eighteen patients with anterior septal perforation who underwent endoscopic repair with the "tunnel technique" based on anterior ethmoid artery flap (AEA) were analyzed. Demographic data, etiology, size of perforation, and success rate were collected. RESULTS: Eighteen cases with male predominance (67%) were enrolled from 2019 to 2022. The average perforation size was 1.5 cm (0.5- 3.6 cm). The success rate of complete SP closure was 94% (n = 17/18) with no complications after surgery. The patients were followed up for 7 ± 5.2 months. CONCLUSIONS: AEA flap reconstruction with the tunnel technique is associated with favorable outcomes in SP closure. The tunnel technique provides a useful flap bolster and minimizes the use of other supportive measures. This technique offers an addition to other techniques for septal perforation repair. LEVEL OF EVIDENCE: Level 4.

Beyond Psychotropic: Potential Repurposing of Fluoxetine toward Cancer Therapy.

Drug repurposing, rebranding an existing drug for a new therapeutic indication, is deemed a beneficial approach for a quick and cost-effective drug discovery process by skipping preclinical, Phase 1 trials and pharmacokinetic studies. Several psychotropic drugs, including selective serotonin reuptake inhibitors (SSRIs) and tricyclic antidepressants (TCAs), were studied for their potential application in different diseases, especially in cancer therapy. Fluoxetine (FLX) is one of the most prescribed psychotropic agents from the SSRIs class for the treatment of several neuropsychiatric disorders with a favorable safety profile. FLX exhibited different oncolytic effects via mechanisms distinct from its main serotonergic activity. Taking advantage of its ability to rapidly penetrate the blood-brain barrier, FLX could be particularly useful in brain tumors. This was proved by different in vitro and in vivo experiments using FLX as a monotherapy or combination with temozolomide (TMZ) or radiotherapy. In this review of the literature, we summarize the potential pleiotropic oncolytic roles of FLX against different cancers, highlighting the multifaceted activities of FLX and its ability to interrupt cancer proliferation via several molecular mechanisms and even surmount multidrug resistance (MDR). We elaborated on the successful synergistic combinations such as FXR/temozolomide and FXR/raloxifene for the treatment of glioblastoma and breast cancer, respectively. We showcased beneficial pharmaceutical trials to load FLX onto carriers to enhance its safety and efficacy on cancer cells. This is the first review article extensively summarizing all previous FLX repurposing studies for the management of cancer.

Pomegranate peel extract is an effective agent against MDR bacteria.

Multidrug-resistant (MDR) bacteria are one of the major public health threats facing humanity. Infections with MDR strains are difficult or impossible to treat with standard antibiotics leading to severe illnesses and even deaths. The spread of MDR bacteria has necessitated the search for alternative approaches that tackle MDR pathogens. Natural plants can be utilized as alternative therapeutic agents against the rise of MDR bacteria. In this study, we aimed to assess the antimicrobial activity of pomegranate peel extracts (PPE) against MDR clinical isolates. A total of 9 clinical isolates (8 MDR and 1 non-MDR clinical isolates) were collected and examined for their susceptibility to PPE. Using the zone of inhibition assay, 4 isolates (S. aureus, three MRSA isolates, Vancomycin-resistant Enterococci (VRE), and Acinetobacter baumannii) were sensitive to PPE. In Broth assay, 4 mg/ml PPE significantly reduced the growth (S. aureus, three MRSA isolates, Vancomycin-resistant Enterococci (VRE), and Acinetobacter baumannii), while 40 mg/ml PPE either significantly reduced or completely inhibited the growth of the isolates. The minimum bactericidal concentration (MBC) of PPE against S. aureus and MRSA-88 was 10 mg/ml. This study showed the potential of PPE as an alternative compound for treating infections caused by PPE-sensitive MDR bacteria.

Exploration of phytochemical compounds against Marburg virus using QSAR, molecular dynamics, and free energy landscape.

Marburg virus disease (MVD) is caused by the Marburg virus, a one-of-a-kind zoonotic RNA virus from the genus Filovirus. Thus, this current study employed AI-based QSAR and molecular docking-based virtual screening for identifying potential binders against the target protein (nucleoprotein (NP)) of the Marburg virus. A total of 2727 phytochemicals were used for screening, out of which the top three compounds (74977521, 90470472, and 11953909) were identified based on their predicted bioactivity (pIC50) and binding score (< - 7.4 kcal/mol). Later, MD simulation in triplicates and trajectory analysis were performed which showed that 11953909 and 74977521 had the most stable and consistent complex formations and had the most significant interactions with the highest number of hydrogen bonds. PCA (principal component analysis) and FEL (free energy landscape) analysis indicated that these compounds had favourable energy states for most of the conformations. The total binding free energy of the compounds using the MM/GBSA technique showed that 11953909 (ΔGTOTAL = - 30.78 kcal/mol) and 74977521 (ΔGTOTAL = - 30 kcal/mol) had the highest binding affinity with the protein. Overall, this in silico pipeline proposed that the phytochemicals 11953909 and 74977521 could be the possible binders of NP. This study aimed to find phytochemicals inhibiting the protein's function and potentially treating MVD.

Bioguided isolation of potential antitumor agents from the aerial parts of cultivated cardoon (Cynara cardunculus var. altilis).

Hepatocellular carcinoma (HCC) is one of the leading causes of mortality worldwide; therefore, searching for an effective treatment for this illness is of great importance. In the present work, in vitro cytotoxic activity of the ethanol extract of the aerial parts of Cynara cardunculus L. against human liver carcinoma cells (Hep G2) was tested. Additionally, the antitumor activity of the extract was confirmed using chemically induced rat liver carcinogenesis with diethylnitrosamine (DEN). Moreover, bioguided fractionation and column chromatographic separation of the active compounds were carried out. The extract of C. cardunculus showed a promising cytotoxic activity according to the protocols of the National Cancer Institute. Bioguided chromatographic separation of the ethanol extract of C. cardunculus led to the isolation of seven secondary metabolites including two sesquiterpene lactones as the principal active components of the methylene chloride soluble fraction, grosheimin (IC50 = 7.49 µg/mL) and cynaropicrin (IC50 = 13.9 µg/mL). The compounds were characterized by different spectroscopic techniques such as EI-MS, IR and NMR. Additionally, in silico analysis of the two active compounds revealed their ability to bind with caspase-3 via hydrogen bonds interactions to initiate apoptosis of cancer cells. The results shed the light on the significance of C. cardunculus as a potential source of antitumor agents.

The Psychological Impact of COVID-19 Pandemic on Persons with Multiple Sclerosis in Saudi Arabia.

OBJECTIVES: To evaluate, in a Saudi Arabian context, how the COVID-19 pandemic psychologically impacted persons with multiple sclerosis (PwMS). METHODS: A cross-sectional study was undertaken during the period from October 2021 to March 2022. 738 participants resident in the Kingdom of Saudi Arabia (KSA) completed a self-administered online questionnaire. The research focused on persons diagnosed with MS. RESULTS: Participant ages spanned from 18 to over 55. The mean was 36.1±12.9 years old. Four hundred eighty-nine (66.3%) of the 738 participants were female. Two hundred sixty-four (35.8%) were single. Four hundred twelve (55.8%) were married. Six hundred eighty-five (92.8%) had received a COVID-19 vaccine. Regarding MS duration, 117 (15.9%) had been diagnosed for less than 2 years, 171 (23.2%) for 2-5 years, while 251 (34%) had the condition for 10 or more years. Regarding psychological health, 11.2% of participants complained of minimal/no depression, 33.3% of mild depression, 28.3% of moderate depression, and 27.1% of moderately severe to severe depression symptoms. Concerning anxiety, 17.2% of participants reported minimal anxiety, 36.9% mild, 23.3% moderate, while 22.6% suffered from severe anxiety symptoms. CONCLUSION: A high prevalence of depression and anxiety was found, along with high prevalence of co-occurrence of these disorders among PwMS.

Recombinant R2-pyocin cream is effective in treating Pseudomonas aeruginosa-infected wounds.

Pseudomonas aeruginosa, a gram-negative opportunistic pathogen, is one of the major species isolated from infected chronic wounds. The multidrug resistance exhibited by P. aeruginosa and its ability to form biofilms that are difficult to eradicate, along with the rising cost of producing new antibiotics, has necessitated the search for alternatives to standard antibiotics. Pyocins are antimicrobial compounds produced by P. aeruginosa that protect themselves from their competitors. We synthesized and purified recombinant P. aeruginosa R2 pyocin and used it in an aqueous solution (rR2P) or formulated in polyethylene glycol (rR2PC) to treat P. aeruginosa-infected wounds. Clinical strains of P. aeruginosa were found to be sensitive (completely), partially sensitive, or resistant to rR2P. In the in vitro biofilm model, rR2P inhibited biofilm development by rR2P-sensitive isolates, while rR2PC eliminated partial biofilms formed by these strains in an in vitro wound biofilm model. In the murine model of excision wounds, and at 24 h post-infection, rR2PC application significantly reduced the bioburden of the clinical isolate BPI86. Application of rR2PC containing two glycoside hydrolase antibiofilm agents eliminated BPI86 from infected wounds. These results suggest that the topical application of rR2PC is an effective therapy for treating wounds infected with R2P-senstive P. aeruginosa strains.

In Vitro Alpha-Amylase and Alpha-Glucosidase Inhibitory Activity and In Vivo Antidiabetic Activity of Withania frutescens L. Foliar Extract.

Withania frutescens L. is a wild perennial woody plant used by the local population for diverse therapeutic purposes. This work aims to study for the first time the potential inhibitory effect of this plant hydroethanolic extract on α-amylase and α-glucosidase activities using in vitro methods and its antidiabetic and antihyperglycemic activities using alloxan-induced diabetic mice as a model for experimental diabetes. Two doses were selected for the in vivo study (200 and 400 mg/kg) and glibenclamide, a well-known antidiabetic drug (positive control) in a subacute study (28 days) where the antihyperglycemic activity was also assessed over a period of 12 h on diabetic mice. The continuous treatment of diabetic mice with the extract of Withania frutescens for 4 weeks succeeded to slowly manage their high fasting blood glucose levels (after two weeks), while the antihyperglycemic test result revealed that the extract of this plant did not control hyperglycemia in the short term. No toxicity signs or death were noted for the groups treated with the plant extract, and it shows a protective effect on the liver and kidney. The in vitro assays demonstrated that the inhibition of alpha-amylase and alpha-glucosidase might be one of the mechanisms of action exhibited by the extract of this plant to control and prevent postprandial hyperglycemia. This work indicates that W. frutescens have an important long term antidiabetic effect that can be well established to treat diabetes.

Evaluation of Cholinesterase Inhibitory Potential of Different Genotypes of Ziziphus nummularia, Their HPLC-UV, and Molecular Docking Analysis.

Ziziphus nummularia is an important source of valuable phytoconstituents, which are widely used in traditional medicine system of Indo-Pak sub-continent. In this study we investigated the distribution of phenolic compounds in the fruit pericarps of six different genotypes (ZNP01-06) of Z. nummularia growing in the unexplored hilly areas of Pakistan. The methanolic extracts of these genotypes were screened for total phenolic content (TPC), total flavonoid content (TFC), antioxidant, and cholinesterase inhibitory potentials. The observed biological potentials were explained in terms of the outcome of molecular docking and HPLC analyses. Among them, genotype ZNP02 displayed high TPC (88.50 ± 1.23 µg/mL) and showed potent scavenging activity against DPPH (67.03 ± 1.04 µg/mL) and ABTS (65.3 ± 1.74 µg/mL) in comparison to ascorbic acid (68.7 ± 0.47 µg/mL). Moreover, genotypes ZNP01, ZNP02, and ZNP04 displayed potent inhibition against acetyl and butyryl cholinesterases (AChE and BChE) with IC50 values of 21.2, 20.5, and 23.7 µg/mL (AChE) and 22.7, 24.4, and 33.1 µg/mL (BChE), respectively. Furthermore, the individual compounds in the most potent species ZNP01 responsible for potent enzyme inhibition (identified through HPLC-UV analysis), were computed via docking simulation software to the enzyme structures. Among these compounds rutin exhibited significant binding affinity with value of -9.20 kcal/mol. The differences amongst the phytochemical compositions of the selected genotypes highlighted the genotypic variations in them. Based on our results it was concluded that the selected plant can be used as remedy of oxidative stress and neurodegenerative diseases. However, further studies are needed to isolate responsible compounds and test the observed potential in vivo, along with toxicological evaluations in animal models.

Impact of an integrated care program on glycemic control and cardiovascular risk factors in patients with type 2 diabetes in Saudi Arabia: an interventional parallel-group controlled study.

BACKGROUND: Long intervals between patient visits and limited time with patients can result in clinical inertia and suboptimal achievement of treatment goals. These obstacles can be improved with a multidisciplinary care program. The present study aimed to assess the impact of such a program on glycemic control and cardiovascular risk factors. METHODS: In a randomized, parallel-group trial, we assigned 263 patients with poorly controlled type 2 diabetes mellitus (T2DM) to either a control group, standard care program, or a multidisciplinary care program involving a senior family physician, clinical pharmacy specialist, dietician, diabetic educator, health educator, and social worker. The participants were followed for a median of 10 months, between September 2013 and September 2014. Glycated hemoglobin (HbA1c), fasting blood glucose (FBG), lipid profiles, and blood pressure (BP) were measured. The assignment was blinded for the assessors of the study outcomes. The study registry number is. RESULTS: In the intervention group, there were statistically significant (p < 0.05) post-intervention (relative) reductions in the levels of HbA1c (-27.1%, 95% CI = -28.9%, -25.3%), FBG (-17.10%, 95% CI = -23.3%, -10.9%), total cholesterol (-9.93%, 95% CI = -12.7%, -7.9%), LDL cholesterol (-11.4%, 95% CI = -19.4%, -3.5%), systolic BP (-1.5%, 95% CI = -2.9%, -0.03%), and diastolic BP (-3.4%, 95% CI = -5.2%, -1.7%). There was a significant decrease in the number of patients with a HbA1c ≥10 (86 mmol/mol) from 167 patients at enrollment to 11 patients after intervention (p < 0.001). However, the intervention group experienced a statistically significant increase in body weight (3.7%, 95% CI = 2.9%, 4.5%). In the control group, no statistically significant changes were noticed in different outcomes with the exception of total cholesterol (-4.10%, p = 0.07). In the linear regression model, the intervention and the total number of clinic visits predicted HbA1c improvement. CONCLUSIONS: Implementation of a patient-specific integrated care program involving a multidisciplinary team approach, frequent clinic visits, and intensified insulin treatment was associated with marked improvement in glycemic control and cardiovascular risk factors of poorly controlled T2DM patients in a safe and reproducible manner. TRIAL REGISTRATION: ISRCTN Identifier: ISRCTN83437562 September 19, 2016 Retrospectively registered.

Innovative real CSF leak simulation model for rhinology training: human cadaveric design.

OBJECTIVE: To study the feasibility of designing a human cadaveric simulation model of real CSF leak for rhinology training. METHOD: The laboratory investigation took place at the surgical academic center of Prince Sultan Military Medical City between 2016 and 2017. Five heads of human cadaveric specimens were cannulated into the intradural space through two frontal bone holes. Fluorescein-dyed fluid was injected intracranialy, then endoscopic endonasal iatrogenic skull base defect was created with observation of fluid leak, followed by skull base reconstruction. The outcome measures included subjective assessment of integrity of the design, the ability of creating real CSF leak in multiple site of skull base and the possibility of watertight closure by various surgical techniques. RESULTS: The fluid filled the intradural space in all specimens without spontaneous leak from skull base or extra sinus areas. Successfully, we demonstrated fluid leak from all areas after iatrogenic defect in the cribriform plate, fovea ethmoidalis, planum sphenoidale sellar and clival regions. Watertight closure was achieved in all defects using different reconstruction techniques (overly, underlay and gasket seal closure). CONCLUSION: The design is simulating the real patient with CSF leak. It has potential in the learning process of acquiring and maintaining the surgical skills of skull base reconstruction before direct involvement of the patient. This model needs further evaluation and competence measurement as training tools in rhinology training.

Contralateral sinus involvement of surgically treated unilateral allergic fungal rhinosinusitis.

Recurrence of allergic fungal rhinosinusitis (AFRS) is well recognized. However, there is scarcity in the literature describing involvement of the non-diseased sinuses. We aimed to evaluate the recurrence forms of unilateral AFRS as well as to study the possible predictor factors of developing the disease in the contralateral side. Patients with exclusive unilateral AFRS from (2010 to 2015) were enrolled in multi-institutional case-control study. All patients were evaluated after endoscopic sinus surgery for recurrence. Patient's records were reviewed for demographics, medical treatment, and clinical, radiological, and surgical data. A total of 68 patients were identified. Delayed contralateral involvement after the initial surgery was found in 30.8% with mean duration of recurrence 16.9 months. A significant association was found with the presence of pre-operative contralateral symptoms and signs of inflammation (OR 3.49, 95% CI 1.19-10.22, p value 0.02). Post-operative use of budesonide irrigation was associated with less contralateral involvement (OR 0.11, 95% CI 0.01-0.87, p value 0.01). Association of other variables like: comorbidities, perioperative use of systemic steroid, radiological signs, extent of surgery, additional surgery to the contralateral side, and post-operative use of systemic steroids did not show statistical significance. Involvement of the contralateral sinuses in 30% of unilateral AFRS cases is considered significant. The non-diseased sinuses should be involved in the routine endoscopic examination and post-operative treatment. Further studies are necessary to investigate the possibility of prophylactic surgical intervention of the non-diseased sinuses.

Public awareness, knowledge, and attitudes toward epilepsy in the Aseer region, Saudi Arabia - A community-based cross-sectional study.

INTRODUCTION: Epilepsy accounts for 0.5% of the global burden of disease, with more than 50 million people affected worldwide; 80% of them are in developing regions. People with epilepsy and their families can suffer from stigma and discrimination in many parts of the world. Although this disorder is common in Saudi Arabia, with a prevalence of 6.54 per 1000, no study of epilepsy awareness, knowledge, and attitudes has been reported from the Aseer region. METHODS: The study was conducted using a validated self-administered questionnaire to assess awareness, knowledge, and attitudes toward epilepsy and the sociodemographic data of the participants. RESULTS: In the total sample of 1044 (mean age: 28±9years; 53.2% were males; from different educational and social levels), almost all had heard about epilepsy (96.1%), and the majority knew someone with epilepsy (60.7%). In spite of that, knowledge about the etiology and nature of epilepsy was lacking, as 40% of participants thought it was a blood disorder, 21.2% believed it was contagious, and nearly one-third viewed it as due to a mental disorder and emotional stress. Regarding public attitudes toward people with epilepsy, 19.1% would not work with them, 17% would not allow having their child mingle with a child with epilepsy at school, and more than half would not marry a person with epilepsy. Moreover, the study showed inappropriate responses when dealing with someone with a seizure; they would force some medicine down the patient's throat (49.3%), use herbal medicine (68.9%), ask a spiritual healer (31.8%), or even think it is untreatable (35.6%). CONCLUSION: The level of epilepsy awareness in the Aseer region's population is relatively poor and needs improvement.

Newly designed double-vascularized nasoseptal flap to prevent restenosis after endoscopic modified Lothrop procedure (Draf III): laboratory investigation.

Despite advances in endoscopic approaches, instrumentations and imaging guidance systems, the management of frontal sinus is still challenging. Failure of the endoscopic procedure and restenosis of the newly formed ostium have been demonstrated even with large frontal sinusotomy. We describe a newly designed double nasoseptal flap to cover the bare bone after endoscopic modified Lothrop procedure (EMLP). Five fresh, double-injected cadavers were dissected through an endoscopic endonasal approach. Posteriorly based nasoseptal flap on one side and laterally based nasoseptal flap on the other side were harvested before performing wide EMLP. Feasibility of the procedure, versatility of the flap, coverage area and measurements were calculated. Harvesting the mucoperichondrial/mucoperiosteal flap over the septectomy site was straightforward step. Two different designed flaps (one on each side) are more practical to avoid torsion of the flap. The flap measures 2 × 3 cm on average that was able to cover the bare bone of the anterior and posterior wall of frontal sinus. Osteoneogenesis and progressive osteoplastic activity after EMLP plays a major role in restenosis of frontal sinus. Vascularized nasoseptal flap helps in preventing closure of the newly formed ostium. Applying these flaps over the bare bone enhances the healing process and minimizes the crust formation.

A case report of simultaneous tears of the medial and lateral posterior meniscal roots with an intact ACL graft.

INTRODUCTION AND IMPORTANCE: Meniscal root tears are defined as soft-tissue and/or osseous injuries that rip or avulse within one centimeter of the meniscal insertion to the tibial plateau. These injuries impact around 100,000 patients a year and make up 10 % to 21 % of all meniscal tears. Meniscal extrusion frequently happens when there are root rips, and the transmission of circumferential hoop loads is hampered. CASE PRESENTATION: We present one case of a 28-year-old male who complained of pain and stiffness in his left knee since 2 years after undergoing ACL reconstruction using a hamstring autograft. His examination revealed joint line tenderness on both the medial and lateral sides of the left knee. Further investigations involving X-ray and MRI established the diagnosis of both medial and lateral meniscal root tears, which were surgically managed using the transtibial pullout technique. DISCUSSION: The biomechanical implications of meniscal root tears, such as loss of hoop forces and increased tibiofemoral contact pressures, underscore the importance of timely diagnosis and management. The literature advocates surgical treatment for managing root tears, as leaving them without surgical intervention can lead to functional outcomes similar to those of total meniscectomy. CONCLUSION: This case report presents both menisci posterior root tears with an intact ACL graft which is unique in that they commonly tear in conjuction with ACL. These kind of injuries necessitates prompt diagnosis and surgical intervention to protect the knee from early arthritic changes.

Congenital absence of the lateral meniscus: A case report.

BACKGROUND: Congenital absence of the menisci is a rare anatomical variation characterized by the absence or underdevelopment of one or both menisci in the knee joint. The menisci are crucial in load distribution, joint stability, and shock absorption. Understanding the clinical presentation, diagnosis, and management of this condition is important for optimal patient care. CASE SUMMARY: A 27-year-old male with a long-standing history of knee pain underwent diagnostic arthroscopy, revealing a congenital absence of the meniscus. The patient's clinical findings, imaging results, surgical procedures, and pertinent images are detailed. This case presents a unique aspect with the congenital absence of the meniscus, contributing valuable insights to the literature on rare anatomical anomalies. CONCLUSION: This case of congenital absence of the menisci highlights the diagnostic challenges posed by rare anomalies. The diagnostic arthroscopy played a crucial role in identifying the absence of the meniscus and providing an explanation for the patient's persistent knee pain. The case underscores the importance of individualized treatment approaches, including physical therapy, for optimal management of rare meniscal anomalies. Further research is warranted to explore effective management strategies for the aforementioned cases and to expand our knowledge of these rare conditions.

Translation, cultural adaptation and validation of Patient Satisfaction with Pharmacist Services Questionnaire (PSPSQ) 2.0 into the Arabic language among people with diabetes.

BACKGROUND: Understanding patient satisfaction is key to advancing pharmacy services and improving health outcomes. There is a lack of a translated and psychometrically validated tool in the Arabic language to measure patient satisfaction with pharmacy services. OBJECTIVE: To translate the English version of the PSPSQ 2.0 into Arabic language, culturally adapt, and verify its reliability and validity. SETTING: A community pharmacy in Riyadh, Saudi Arabia. METHOD: A cross-sectional study was conducted between April 2021 and June 2022 among patients with diabetes attending a community pharmacy. The International Society for Pharmacoeconomics and Outcomes Research good practice guidelines for linguistic translation and cultural adaptation were used to translate and culturally adapt the English version of PSPSQ 2.0 into Arabic. The Arabic version of PSPSQ 2.0 was subjected to factor analysis using principal component analysis with varimax rotation to evaluate its validity and Cronbach's alpha was used to assess the reliability of PSPSQ 2.0. RESULTS: A total of 129 (68.2% male, and mean age 50 (SD: 11.9) years) patients with diabetes participated in the study. The analysis was undertaken for the items in each of the three domains of PSPSQ 2.0: quality of care, interprofessional relationship and overall care. Exploratory factor analysis revealed validity of 92.7%, 80.5% and 96.2%, respectively. The Arabic version of PSPSQ 2.0 had high internal consistency with Cronbach's alpha scores 0.99, 0.95 and 0.98 for the three measured domains, respectively. The sample adequacy was 0.924. CONCLUSION: The PSPSQ 2.0 was successfully translated and culturally adapted into the Arabic language and had acceptable validity and reliability to measure patient satisfaction with services provided by pharmacists in community pharmacies.
