RESUMO

Purpose: Juniper (Juniperus procera) is a common forest tree species in Saudi Arabia. The decline in many populations of J. procera in Saudi Arabia is mainly due to seed dormancy and loss of natural regeneration. This study assessed the effects of chemical and hormonal treatments on seed germination and seedling growth in juniper plants. Methods: The seeds were subjected to either chemical scarification with 90% sulfuric acid and 20% acetic acid for 6 min or hormonal treatment by seed soaking in two concentrations (50 and 100 ppm) of three growth regulators, namely, indole acetic acid (IAA), gibberellins (GA3), and kinetin, for 72 h. A control group without any seed treatment was also prepared. The experiments were performed in an incubator maintained at room temperature and under a light and dark period of 12 h for 6 w. The germinated seeds for each treatment were counted and removed from the dishes. The selected germinated seeds from different treatments were planted in a greenhouse and irrigated with tap water for another 6 weeks. The hormone-treated seedlings were sprayed with their corresponding hormone concentrations 1 w after planting. Results: The highest percentage of seed germination was significantly recorded after seed soaking in 50 ppm GA3, whereas treatment with IAA (100 ppm) resulted in the best seedling growth. Seedlings treated with the three phytohormones showed a significant increase in photosynthetic pigments, total soluble sugars, proteins, percentage of oil, IAA, GA3, and kinetin contents of juniper seedlings compared with the control value, whereas abscisic acid content was decreased compared with chemical treatments. Conclusion: The investigated different treatments had an effective role in breaking seed dormancy and improving seedling growth of J. procera, which is facing a notable decline in its population worldwide. Moreover, such an effect was more pronounced in the three phytohormones that succeeded in breaking dormancy and growth of the Juniperus plant than in the other treatments.

RESUMO

BACKGROUND: Recent estimates indicate that a significant proportion of diabetic patients globally, up to 51%, are utilizing complementary and alternative medicine (CAM). To improve patient-provider communication and optimize prescribed treatments, healthcare professionals (HCPs) must understand the factors associated with CAM use among diabetic patients. There is a dearth of literature on HCPs perspectives on CAM use by diabetic patients. This study explored HCPs knowledge, perspective, and views on their diabetic patients' use of CAM. METHODS: Qualitative study using one-to-one semi-structured interviews conducted with 22 HCPs involved in the care of diabetic patients (6 endocrinologists, 4 general practitioners, 4 nurses and 8 pharmacists). Participants were recruited through general practices, community pharmacies and a diabetic centre in Saudi Arabia. Data were analyzed using thematic analysis. RESULTS: Five key themes resulted from the analysis. HCPs generally demonstrated negative perceptions toward CAM, particularly regarding their evidence-based effectiveness and safety. Participants described having limited interactions with diabetic patients regarding CAM use due to HCPs' lack of knowledge about CAM, limited consultation time and strict consultation protocols. Participants perceived convenience as the reason why patients use CAM. They believed many users lacked patience with prescribed medications to deliver favourable clinical outcomes and resorted to CAM use. CONCLUSIONS: HCPs have noted inadequate engagement with diabetic patients regarding CAM due to a lack of knowledge and resources. To ensure the safe use of CAM in diabetes and optimize prescribed treatment outcomes, one must address the communication gap by implementing a flexible consultation protocol and duration. Additionally, culturally sensitive, and evidence-based information should be available to HCPs and diabetic patients.

RESUMO

INTRODUCTION: Urinary tract infections (UTIs) are common in children. UTIs can lead to serious and permanent damage to the urinary tract if treatment is delayed or insufficient, particularly in repeated infections. Knowledge of antibiotic resistance trends aids in the selection of appropriate empiric antibiotics. There is limited data regarding this in Saudi Arabia. This study aimed to investigate uropathogens and their antibiotic resistance patterns in the pediatric community in a tertiary care center. METHODOLOGY: The study population included children aged 0 to 14 years old who had culture-proven UTIs evaluated in the Department of Pediatrics, King Abdulaziz University Hospital in Jeddah, Saudi Arabia from February 2019 to September 2021. RESULTS: Out of 510 UTI episodes, Escherichia coli (54.5%) was the predominant causative pathogen. Of the total episodes, 137 (26.8%) were caused by extended spectrum beta-lactamase (ESBL) producers. In general, the highest resistance was observed against ampicillin (73.2%), cefazolin (54.6%), co-trimoxazole (46%), and cefuroxime (40.6%), whereas amikacin (0.4%), imipenem (0.8%), and meropenem (0.8%) showed the lowest rates of resistance. CONCLUSIONS: Antibiotic resistance is a major concern worldwide due to misuse of antibiotics and subsequent rise of multidrug resistant organisms. Our findings highlight the rise in antibiotic resistance, particularly in E. coli strains. Furthermore, ESBL-producing bacteria were responsible for approximately one-third of UTIs. Our study emphasizes the importance of local antibiograms for pediatric community-acquired infections, as it guides clinicians in every center in the choice of appropriate empiric antibiotic treatment.

RESUMO

BACKGROUND: Breast cancer (BC) is a prevalent form of cancer and a leading cause of death among women worldwide. In Saudi Arabia, it accounted for 31.8% among females of all new cancer cases reported in 2018. Following the declaration of COVID-19 as a global pandemic, there was a complete redistribution of healthcare resources to face this crisis, which caused a significant delay in the management of various diseases, including BC. There is currently a lack of research in our region on the facility time interval in BC management. Therefore, this study aimed to fill this gap by determining the timelines of diagnosis, management, and factors influencing the delay. METHODS: This observational retrospective study included all female patients diagnosed with BC at or referred to King Abdullah Medical City (KAMC) in Makkah, Saudi Arabia, between January 2020 and August 2021. The data for this study were obtained from a centralized electronic chart review of all included patients at the KAMC center. RESULTS: A total of 76 patients were included in the study, with a mean age of 50 ± 11 years. In terms of the disease management duration, 20 patients (26.3%) completed their management within 30 days, 28 patients (36.8%) had a management duration between 31 and 60 days, and the management duration of 28 patients (36.8%) exceeded 60 days. Patient deposition showed a significant association with delay (p = 0.033). A higher incidence of delays at the initiation of treatment was observed in patients who failed to attend appointments (p < 0.001). Among patients who skipped two or more appointments, 12 individuals (80%) experienced a delay of more than 60 days. Moreover, appointment cancellation was associated with delayed treatment initiation (p = 0.03). Patients' age and comorbidity showed no significant association (p = 0.49, p = 0.24, respectively). CONCLUSION: Our findings highlight the significant impact of patient deposition and canceled or skipped appointments on delayed initiation of therapy for BC patients. Further research should be conducted to evaluate the impact of COVID-19 on other malignancies.

RESUMO

OBJECTIVES: Clearing secretions from the airway can be difficult for people with chronic obstructive pulmonary disease (COPD). Mucus clearance devices (MCDs) are an option in disease management to help with this, but healthcare provider awareness and knowledge about them as well as current clinical practice in Saudi Arabia are not known. DESIGN: A cross-sectional online survey consisting of four themes; demographics, awareness, recommendations and clinical practice, for MCDs with COPD patients. SETTING: Saudi Arabia. PARTICIPANTS: 1188 healthcare providers including general practitioners, family physicians, pulmonologists, nursing staff, respiratory therapists and physiotherapists. PRIMARY OUTCOME MEASURES: Healthcare providers' level of awareness about MCDs, and the identification of current clinical practices of COPD care in Saudi Arabia. RESULTS: 1188 healthcare providers (44.4% female) completed the survey. Regarding devices, 54.2% were aware of the Flutter, 23.8% the Acapella and 5.4% the positive expiratory pressure mask. 40.7% of the respondents identified the Acapella, and 22.3% the Flutter as first choice for COPD management. 75% would usually or always consider their use in COPD patients reporting daily difficulty clearing mucus, whereas 55.9% would sometimes or usually consider the use of MCDs with COPD patients who produced and were able to clear mucus with cough. In clinical practice, 380 (32%) of the respondents would prescribe MCDs, 378 (31.8%) would give MCDs without prescriptions, 314 (26.4%) would not provide them at all and 116 (9.8%) would only advise patients about them. CONCLUSION: Healthcare providers are aware of the existence of MCDs and their benefits for sputum clearance and believe that MCDs are beneficial for sputum clearance in some COPD patients. TRIAL REGISTRATION NUMBER: ISRCTN44651852.

RESUMO

BACKGROUND: This study aimed to evaluate the demographics, clinical characteristics, risk factors, and antibiotic resistance of pediatric community-acquired urinary tract infections (UTIs) caused by extended-spectrum beta-lactamase (ESBL)-producing and non-ESBL-producing uropathogens. METHODS: This retrospective study was conducted at a tertiary care hospital in Saudi Arabia, among children aged between 0 and 14 years, with a culture-proven diagnosis of community-acquired UTI between February 2019 and September 2021. Patients were divided into two groups based on whether or not their UTI was caused by ESBL-producing bacteria. RESULTS: A total of 383 patients with community-acquired UTI were evaluated. Escherichia coli was detected in 72.6% of cultures. Extended-spectrum beta-lactamase-producing organisms were responsible for 35.7% of UTI episodes. Of these 69% and 31% were caused by E. coli and Klebsiella pneumoniae, respectively. There were no significant differences between the two groups with regard to clinical presentation or urine analysis. The resistance rates in the ESBL-producing group were 39.4% for amoxicillin/clavulanic acid, 65.7% for ciprofloxacin, 72.3% for co-trimoxazole, 32.8% for nitrofurantoin, 21.2% for gentamicin, and 0.7% for amikacin and carbapenems. In the non-ESBL-producing group, it was 22.4% for amoxicillin/clavulanic acid, 22.4% for ciprofloxacin, 38.2% for co-trimoxazole, 23.6% for nitrofurantoin, 6.1% for gentamicin, and zero for amikacin and carbapenems. The presence of renal abnormalities (p = 0.014) and male gender (p = 0.026) were determined to be independent risk factors for ESBL UTIs. CONCLUSIONS: Recognizing risk factors and antibiotic resistance for ESBL-producing bacteria may aid in tailoring an antibiotic regimen for pediatric patients at high risk of ESBL-UTIs.

RESUMO

OBJECTIVE: To identify the prognostic factors of surgical resection for meningioma and their relationship with patient outcomes. METHODS: This retrospective study included 53 patients (≥16 years), who underwent surgical resection for intracranial meningioma at the King Abdulaziz University Hospital from 2012 to 2022. Data regarding tumor location and size, histopathological type, chief complaint, chief complaint duration, admission date, diagnosis, operation, and discharge date were collected. These data were subjected to univariate and bivariate analyses to investigate the relationship between the postsurgical outcomes of the patients with meningioma and the variables of age at surgery, sex, length of hospitalization, chief complaint, Glasgow outcome score, World Health Organization histopathological classification, body mass index, tumor size, and nature of surgical resection. RESULTS: The mean age of our study cohort was 49.09 ± 12.64 years, with a female preponderance (75.5%) and mean body mass index of 29.31 ± 5.52 kg/m2. length of hospitalization (mean: 26.92 ± 54.88 days) demonstrated a significant (P = 0.012) impact on prognosis after surgery. In addition, convexity meningiomas (21.2%), which were observed in the maximum number of cases, and mean tumor volume (28.67 ± 48.85 mm) were significantly (P = 0.049) associated with the outcome. Most patients (78.8%) underwent total surgical resection, and histopathological examinations revealed a higher frequency of grade 1 than grade 2 tumors. CONCLUSIONS: Short duration of hospitalization and superficial location of the tumor are associated with optimal outcomes after surgical resection for patients with meningioma.

RESUMO

Non-small-cell lung cancer (NSCLC) mortality and new case rates are both on the rise. Most patients have fewer treatment options accessible due to side effects from drugs and the emergence of drug resistance. Bedaquiline (BQ), a drug licensed by the FDA to treat tuberculosis (TB), has demonstrated highly effective anti-cancer properties in the past. However, it is difficult to transport the biological barriers because of their limited solubility in water. Our study developed a UPLC method whose calibration curves showed linearity in the range of 5 ng/mL to 500 ng/mL. The UPLC method was developed with a retention time of 1.42 and high accuracy and precision. Its LOQ and LOD were observed to be 10 ng/mL and 5 ng/mL, respectively, whereas in the formulation, capmul MCM C10, Poloxamer 188, and PL90G were selected as solid lipids, surfactants, and co-surfactants, respectively, in the development of SLN. To combat NSCLC, we developed solid lipid nanoparticles (SLNs) loaded with BQ, whereas BQ suspension is prepared by the trituration method using acacia powder, hydroxypropyl methylcellulose, polyvinyl acrylic acid, and BQ. The developed and optimized BQ-SLN3 has a particle size of 144 nm and a zeta potential of (-) 16.3 mV. whereas BQ-loaded SLN3 has observed entrapment efficiency (EE) and loading capacity (LC) of 92.05% and 13.33%, respectively. Further, BQ-loaded suspension revealed a particle size of 1180 nm, a PDI of 0.25, and a zeta potential of -0.0668. whereas the EE and LC of BQ-loaded suspension were revealed to be 88.89% and 11.43%, respectively. The BQ-SLN3 exhibited insignificant variation in particle size, homogeneous dispersion, zeta potential, EE, and LC and remained stable over 90 days of storage at 25 °C/60% RH, whereas at 40 °C/75% RH, BQ-SLN3 observed significant variation in the above-mentioned parameters and remained unstable over 90 days of storage. Meanwhile, the BQ suspension at both 25 °C (60% RH) and 40 °C (75% RH) was found to be stable up to 90 days. The optimized BQ-SLN3 and BQ-suspension were in vitro gastrointestinally stable at pH 1.2 and 6.8, respectively. The in vitro drug release of BQ-SLN3 showed 98.19% up to 12 h at pH 7.2 whereas BQ suspensions observed only 40% drug release up to 4 h at pH 7.2 and maximum drug release of >99% within 4 h at pH 4.0. The mathematical modeling of BQ-SLN3 followed first-order release kinetics followed by a non-Fickian diffusion mechanism. After 24 to 72 h, the IC50 value of BQ-SLN3 was 3.46-fold lower than that of the BQ suspension, whereas the blank SLN observed cell viability of 98.01% and an IC50 of 120 g/mL at the end of 72 h. The bioavailability and higher biodistribution of BQ-SLN3 in the lung tumor were also shown to be greater than those of the BQ suspension. The effects of BQ-SLN3 on antioxidant enzymes, including MDA, SOD, CAT, GSH, and GR, in the treated group were significantly improved and reached the level nearest to that of the control group of rats over the cancer group of rats and the BQ suspension-treated group of rats. Moreover, the pharmacodynamic activity resulted in greater tumor volume and tumor weight reduction by BQ-SLN3 over the BQ suspension-treated group. As far as we are aware, this is the first research to look at the potential of SLN as a repurposed oral drug delivery, and the results suggest that BQ-loaded SLN3 is a better approach for NSCLC due to its better action potential.

RESUMO

Flavonoids are hydroxylated phenolic substances in vegetables, fruits, flowers, seeds, wine, tea, nuts, propolis, and honey. They belong to a versatile category of natural polyphenolic compounds. Their biological function depends on various factors such as their chemical structure, degree of hydroxylation, degree of polymerization conjugation, and substitutions. Flavonoids have gained considerable attention among researchers, as they show a wide range of pharmacological activities, including coronary heart disease prevention, antioxidative, hepatoprotective, anti-inflammatory, free-radical scavenging, anticancer, and anti-atherosclerotic activities. Plants synthesize flavonoid compounds in response to pathogen attacks, and these compounds exhibit potent antimicrobial (antibacterial, antifungal, and antiviral) activity against a wide range of pathogenic microorganisms. However, certain antibacterial flavonoids have the ability to selectively target the cell wall of bacteria and inhibit virulence factors, including biofilm formation. Moreover, some flavonoids are known to reverse antibiotic resistance and enhance the efficacy of existing antibiotic drugs. However, due to their poor solubility in water, flavonoids have limited oral bioavailability. They are quickly metabolized in the gastrointestinal region, which limits their ability to prevent and treat various disorders. The integration of flavonoids into nanomedicine constitutes a viable strategy for achieving efficient cutaneous delivery owing to their favorable encapsulation capacity and diminished toxicity. The utilization of nanoparticles or nanoformulations facilitates drug delivery by targeting the drug to the specific site of action and exhibits excellent physicochemical stability.

RESUMO

Background Crescentic glomerulonephritis (CrGN) is a pathological description of rapidly progressive glomerulonephritis (RPGN). It is characterized by renal failure and is associated with a grave prognosis. This study aimed to investigate the clinical outcomes of patients diagnosed with crescentic glomerulonephritis at the King Abdulaziz University Hospital (KAUH) in Jeddah, Saudi Arabia. Method This retrospective study included patients with CrGN who underwent treatment at the nephrology department at KAUH from June 2021 to August 2022. We collected and analyzed data from 56 patients diagnosed with CrGN on the basis of renal biopsies between 2002 and 2015. Result The study included 17 cases of CrGN. The mean age of patients at the time of diagnosis was 18.06 ± 13.49 years. The distribution of histological findings showed that cellular crescents (94.1%) and interstitial fibrosis and tubular atrophy (IFTA) (76.5%) were the most commonly observed histological findings. The most common underlying etiology was lupus nephritis (41.2%). Regarding the lab results, the mean serum creatinine level at admission was 378.88 ± 273.27 µmol/L, proteinuria was 1.53 ± 1.23 and glomerular filtration rate (GFR) level was 36.94 ± 45.08 mL/min. The factors associated with poor renal outcome were IFTA (P=0.01), phosphate level before discharge, serum creatinine level before and after discharge (P=0.032), and GFR level after discharge (P=0.001). Conclusion Crescentic glomerulonephritis is an important cause of acute kidney injury due to its potential to result in severe glomerular injury. In our study, 12 out of 17 patients experienced poor renal outcomes, which were associated with a high risk of morbidity and mortality. Therefore, early detection and treatment of CrGN is crucial in order to manage the disease.

RESUMO

Background Antibiotic overuse is a critical global health issue, and patient attitudes and expectations play a significant role in the inappropriate use of antibiotics. Limited research has been conducted on patient knowledge, attitudes, and perceptions of antibiotic use in Saudi Arabia. This survey aimed to assess patients' knowledge and attitudes related to antibiotic use in Jeddah, Saudi Arabia. Methods A cross-sectional survey using a convenience sampling method was conducted in Saudi Arabia. An online self-administered questionnaire was used to collect demographic data, antibiotic knowledge, and attitudes. Results The study included 400 patients, with a mean age of 39 years and an equal gender distribution (54% female). Most participants (75%) had not used antibiotics in the past year. Patients demonstrated moderate knowledge about antibiotics, with 81% recognizing that antibiotics can cause side effects and 69% knowing that overuse can lead to resistance. However, only 44% knew that antibiotics are not effective for all infections, and only half (50%) knew that antibiotics work against bacteria, not viruses. Patients held mixed attitudes toward antibiotic prescribing, with 25% believing it was essential to take antibiotics for every infection and 44% believing healthcare providers should prescribe antibiotics for respiratory tract infections. Logistic regression analyses showed that patient expectations for antibiotic prescribing were strongly associated with inappropriate antibiotic use. In contrast, patient satisfaction with antibiotic prescribing was negatively associated with inappropriate antibiotic use. Lower health literacy levels were also associated with inappropriate antibiotic use. Conclusion The study underscores the need for interventions that promote patient education and communication to ensure appropriate antibiotic use in primary care. Patient attitudes and beliefs, such as their expectations for antibiotic prescribing and health literacy levels, were identified as significant predictors of inappropriate antibiotic use.

RESUMO

Alzheimer's disease (AD) is a deadly, progressive, and irreversible brain condition that impairs cognitive abilities. Globally, it affects 32.6 million individuals, and if no viable therapies are available by 2050, that figure might rise to 139 million. The current course of treatment enhances cognitive abilities and temporarily relieves symptoms, but it does not halt or slow the disease's development. Additionally, treatments are primarily offered in conventional oral dosage forms, and conventional oral treatments lack brain specialization and cause adverse effects, resulting in poor patient compliance. A potential nanotechnology-based strategy can improve the bioavailability and specificity of the drug targeting in the brain. Furthermore, this review extensively summarizes the applications of nanomedicines for the effective delivery of drugs used in the management of AD. In addition, the clinical progress of nanomedicines in AD is also discussed, and the challenges facing the clinical development of nanomedicines are addressed in this article.

RESUMO

Background A common psychiatric problem called attention-deficit hyperactivity disorder (ADHD) is characterized by impulsivity with resultant behavior issues and a very short attention span. The purpose of this study was to evaluate and compare the management of dental procedures in children with and without ADHD employing various behavior modification techniques. Materials and methods The study consisted of 121 children divided into two groups with 60 children diagnosed with ADHD and 60 children without ADHD between 7 and 15 years of age. Each of the three sessions, which were spaced a week apart, included a dental examination, oral prophylaxis, and a minor restorative procedure. The pulse rate (PR) and oxygen saturation (SpO2) were measured during each of these sessions. The study was conducted to evaluate the Tell-Show-Do (TSD) method, audiovisual distraction, and pharmacological management of children with and without ADHD during the dental procedure. IBM SPSS Statistics for Windows, Version 22 (Released 2013; IBM Corp., Armonk, New York, United States) was used to statistically analyze the findings. The mean values of the parameters from the three sessions were analyzed and compared using the Z-test. Result The children with ADHD included 39 (65%) boys and 21 (35%) girls, and the children without ADHD consisted of 27 (44.26%) boys and 33 (54.09%) girls. The mean values of the PR during sessions two and three were found to be statistically highly significant between the children with and without ADHD for TSD and audiovisual aids. In both groups, the mean SpO2 values for all the sessions were found to be statistically highly significant for the techniques evaluated (p<0.01). The change in the mean PR score for the ADHD children revealed a declining trend from sessions one through three for all the techniques evaluated (p<0.05), demonstrating a statistically significant effectiveness of the various techniques between the two groups and thereby revealing a decreased level of anxiety. Between sessions one and three, all of the three techniques showed a decreasing trend of SpO2 scores, with the exception of the pharmacological management of ADHD children (p<0.01) indicating that the uncontrollable ADHD children feel less anxious than in the other two approaches. Conclusion The findings of the study demonstrated that behavior management techniques were found to be effective at reducing anxiety in ADHD children than in children without ADHD. Our study further suggests that scheduling dental appointments into a series of short visits could enhance the effectiveness of the therapy and better cooperation of the children.

RESUMO

Background Non-adherence to medication is a common problem in managing chronic diseases, which are a significant public health concern globally. This study aimed to identify factors related to medication adherence among patients with chronic diseases in Saudi Arabia. Methods A cross-sectional survey design was used to collect data through an online survey administered to 400 patients with chronic diseases residing in Jeddah between January and March 2023. The survey included questions about socio-demographic characteristics, chronic disease diagnosis, medication adherence, and factors that may influence medication adherence. Results This study recruited 400 participants and found that the majority were female, with a mean age of 46.2 years, and most had at least one chronic disease, with hypertension and diabetes being the most common. The medication adherence score for the entire sample was 5.4, indicating moderate adherence. Overall, 22.9% of study participants had poor adherence to medications. Factors associated with medication adherence included age, gender, and education level, with older age, female gender, and higher education being positively associated with adherence. Medication-related factors such as the number of medications prescribed, medication complexity, and medication cost were also found to be significantly associated with medication adherence. Conclusion Our study of medication adherence among chronic disease patients in Saudi Arabia found that adherence rates were moderate, with several factors significantly associated with better adherence. Specifically, older age, female gender, and higher education level were positively associated with better adherence, while a higher number of prescribed medications, more complex medication regimens, and higher medication costs were all significant predictors of poorer adherence.

RESUMO

Background In recent years, there has been an increase in the use of the internet and information technology for accessing health information. This study aimed to determine the factors that affect patients with neurological disabilities and their willingness to search for information via the internet. In addition, we aimed to assess how patients manage this information, considering the increasing availability of online information and websites that discuss health and diseases, as well as the spread of communication technology and its accessibility to the public. Methodology A cross-sectional, online, self-administered, questionnaire study was conducted in Saudi Arabia. The study targeted patients with neurological diseases who had disabilities. The questionnaire was designed to measure the demographic data, physical disability using the 10-item physical function component of the 36-Item Short Form Health survey, the perceived usefulness of online health information, the perceived ease of use, and the perceived risk of online health information. Lastly, the questionnaire measured online health information-seeking intentions and information use. Data analysis was performed using RStudio (R version 4.1.1, Posit, Boston, USA). Results We received 1,179 responses, of which 399 were excluded due to using another way to get information rather than the internet, 31 did not have neurological disabilities, and 136 did not complete the questionnaire. The remaining 613 responses were included in the final analysis. The participants were mostly male (54.6%), not married (54.6%), and had a bachelor's degree (49.99%). The average age of participants was 18-25 years (24.5%) and 26-35 years (23.2%), Additionally, most participants resided in the western (26.9%) and eastern (25.9%) regions. Most participants (39.5%) had a monthly income of 5,000 to 10,000 SAR. Further, the most common neurological diseases were multiple sclerosis and epilepsy (26.9% and 23.2%, respectively). Based on the analysis of the data, the most important factor affecting online health information-seeking intention was that people with higher monthly incomes were more likely to seek online health information; these included people with an income of 10,000-20,000 SAR and >20,000 SAR. The most common factor affecting information use was the region of residence. The southern and western regions were less likely to adopt information use. Conclusions The monthly income and the area of residence had the greatest impact on people with neurological disabilities who sought online health information in the Kingdom of Saudi Arabia. Educational campaigns and workshops should be arranged to increase the population's awareness of this topic, as well as to reveal the extent and prevalence of online health information seeking among disabled patients.

RESUMO

BACKGROUND: Due to its high morbidity and mortality after open-heart surgery, sternal wound infection (SWI) is one of the most important consequences to avoid and manage. AIM: To assess the incidence, risk factor, causative organisms, and mortality of SWIs in patients who had open-heart surgery over a 9-year period at King Abdulaziz University Hospital, Jeddah, Saudi Arabia. METHODS: A retrospective study was done on 634 patients who underwent open heart surgery. Data was collected, including patient demographics, BMI, blood group, diabetes, hyperlipidemia, COPD, previous cardiac surgery, previous myocardial infarction, duration of the operation, blood transfusion during the operation, hospital length of stay, and bypass time with each type of sternal wound infection. RESULTS: The incidence of SSWI and DSWI was 8.6% and 4.1%, respectively. Coagulase-negative staphylococcus was the most frequently isolated organism from SSWI and DSWI patients. A concomitant diabetes mellitus that necessitates blood transfusion was identified as one of the risk variables for SSWI in a multivariate regression study. While concomitant diabetes, being a woman, and a lengthy hospital stay were independently linked with DSWI. Compared with the SSWI group, the 30-day mortality rate for DSWI patients was 3.8% as opposed to 3.7%, and the difference in survival was not statistically significant. Having an older, longer bypass time, and postoperative problems were independent risk factors for 30-day mortality. CONCLUSION: Future studies in various healthcare settings are required in order to generalize the results because this was a single center study.

RESUMO

The analytical quality by design (AQbD) approach is utilized for developing and validating the simple, sensitive, cost-effective reverse-phase high performance liquid chromatographic method for the estimation of xanthohumol (XH) in bulk and nanoformulations. The Box-Behnken design (BBD) is applied for method optimization. The mobile phase ratio, pH and flow rate were selected as independent variables, whereas retention time, peak area, peak height, tailing factor, and theoretical plates were selected as dependent variables. The chromatogram of XH obtained under optimized conditions has given optimum conditions such as retention time (5.392 min), peak area (1,226,737 mAU), peak height (90,121 AU), tailing factor (0.991) and theoretical plates (4446.667), which are contoured in the predicted values shown by BBD. Validation of the method has been performed according to ICH Q2(R1) recommendations, using optimized conditions for linearity, limit of detection (LOD) and limit of quantification (LOQ), accuracy, precision, robustness and system suitability. All the values of validation parameters lie within the acceptable limits prescribed by ICH. Therefore, the developed and validated method of XH by the AQbD approach can be applied for the estimation of XH in bulk and various nanoformulations.

RESUMO

INTRODUCTION: Erectile dysfunction (ED) is a prevalent condition, especially in aging populations, with significant implications for quality of life. While phosphodiesterase type 5 inhibitors (PDE5Is) are the first-line treatment, a substantial percentage of patients do not respond satisfactorily. This study aimed to identify predictors of PDE5I treatment failure in ED patients. METHODS: Data from January 2016 to January 2022 was reviewed for patients with ED who either failed PDE5I treatment or had a successful outcome. Demographic, medical, and laboratory data were collected and analyzed. Patients with contraindications or who did not complete the treatment were excluded. RESULTS: The treatment failure group comprised 288 patients, while 225 age-matched patients formed the control responder group. There were no significant differences in marriage duration, comorbidities, smoking, or BMI. However, HbA1c levels, free testosterone, and SHBG were significantly different between the two groups. CONCLUSION: This study found that high HbA1c levels, low free testosterone, and high sex hormone-binding globulin (SHBG) were associated with PDE5I treatment failure. Managing high HbA1c levels and addressing hormonal imbalances may enhance PDE5I treatment effectiveness in ED patients. However, further research is needed to explore other factors contributing to treatment outcomes.

RESUMO

BACKGROUND: It may be necessary to admit patients receiving Hyperthermic Intraperitoneal Chemotherapy (HIPEC) to the intensive care unit (ICU). They were required to evaluate the length of ICU stay (LOS) following HIPEC, as well as their survival rates and risk factors that influence LOS. METHODS: 74 HIPEC patients were observed after being admitted to the ICU. Their assignments were made based on their LOS at the ICU. Short stay group, patients who stayed in the ICU for three days or less (S-group) and patients who stayed for three days or longer (L-group). RESULTS: Survival rates for both groups were comparable. After HIPEC, they exhibited intraoperative hypotension (P = 0.015), hyopthermia (P = 0.014), and hyperglycemia (P = 0.010). Additionally, patients in group L underwent longer surgeries (P = 0.013), lost more blood (P = 0.043), and required more transfusions (P = 0.001). Subjects in group-L had higher SOFA, fentanyl, and vasopressor requirements (all P 0.001), higher ALT and AST levels, disrupted K, lower Na, and higher INR levels (all P 0.001), as well as a higher APACHE II score (P = 0.007). Preoperative BUN had an independent risk factor for LOS of 0.861; (95% CI), (0.742- 0.999); P = 0.048; and crystalloid transfusion had an independent risk factor of 1.000; (95% CI), (0.999- 1.000); P = 0.003. CONCLUSIONS: Transfusions of crystalloids and BUN were independent risk factors for extended LOS. ICU LOS had no impact on survival. All measures should be taken to control hemostasis in vulnerable HIPEC participants.
