Evaluation of time to sputum smear conversion and its association with treatment outcomes among drug-resistant tuberculosis patients: a retrospective record-reviewing study

Background: This study examined the time to sputum smear and culture conversion and determinants of conversion, as well as variables associated with treatment outcomes among drug-resistant pulmonary tuberculosis (DR-PTB) cases.Methods: The electronic database and written medical records of patients were utilized to assess the sociodemographic, clinical, microbiological, and treatment characteristics and outcomes of study participants.Results: Among 736 patients with pulmonary tuberculosis (PTB), the mean age was 36.5 ± 16.5 years, with males comprising 53.4% and a mean weight of 47.76 ± 11.97 kg. The median time period for sputum smear conversion and sputum culture conversion was a month. The first-month culture conversion (p < 0.001, aOR = 5.817, and 95% CI = 3.703–9.138) was the determinant of sputum smear conversion and receiver operating curve analysis with AUC = 0.881, 95% CI = 0.855–0.907, and p < 0.001, which showed a high level of predictive ability for the regression model for the initial sputum smear conversion. However, the first-month sputum conversion (p < 0.001, aOR = 7.446, and 95% CI = 4.869–11.388) was attributed to sputum culture conversion, and the model has shown excellent predictive ability for regression with ROC curve analysis demonstrating AUC = 0.862, 95% CI = 0.835–0.889, and p < 0.001. A total of 63.2% of patients showed favorable treatment outcomes, with 63.1% of cases achieving treatment-cured status. The previous use of SLD, history of smoking, duration of illness ≤ 1 year, extensively drug-resistant tuberculosis, and first-month sputum conversion were the variables attributed to favorable treatment outcomes observed in drug-resistant pulmonary tuberculosis cases. ROC curve analysis with AUC = 0.902, 95% CI = 0.877–0.927, and p < 0.001) has shown outstanding ability for regression model prediction for the variables influencing treatment outcomes.Conclusions: Within 2 months of treatment, most patients had converted their sputum cultures and sputum smears. The determinants of early sputum smear and sputum culture conversion, as well as favorable treatment outcomes, were identified. These factors should be considered during the design and implementation of effective strategies for drug-resistant tuberculosis control programs

A robust computational investigation on C₆₀ fullerene nanostructure as a novel sensor to detect SCNˉ

This study explored on the adsorption properties and electronic structure of SCNˉ via density functional theory analysis on the exterior surfaces of C₆₀ and CNTs using B3LYP functional and 6-31G** standard basis set. Then adsorption of SCNˉ through nitrogen atom on the C60 fullerene is electrostatic (₋48.02 kJ molˉ1) in comparison with the C₅₉Al fullerene that shows covalently attached to fullerene surface (₋389.10 kJ mol̄ˉ1). Our calculations demonstrate that the SCNˉ adsorption on the pristine and Al-doped single-walled CNTs are ₋173.13 and ₋334.43 kJ molˉ1, indicating that the SCNˉ can be chemically bonded on the surface of Al-doped CNTs. Moreover, the adsorption of SCNˉ on the C₆₀ surface is weaker in comparison with C₅₉B, C₅₉Al, and C₅₉Ga systems but its electronic sensitivity improved in comparison with those of C₅₉B, C₅₉Al, and C₅₉Ga fullerenes. The evaluation of adsorption energy, energy gap, and dipole moment demonstrates that the pure fullerene can be exploited in the design practice as an SCNˉ sensor and C₅₉Al can be used for SCNˉ removal application

Reducing the environmental impact of surgery on a global scale: systematic review and co-prioritization with healthcare workers in 132 countries

Abstract Background Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres. Methods This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low–middle-income countries. Results In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of ‘single-use’ consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low–middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia. Conclusion This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high– and low–middle–income countries

Home Drug Delivery Service from the Perspective of Community Pharmacy Staff in Saudi Arabia

Background: In response to COVID-19, many big pharmacy chains in Saudi Arabia have started to provide home drug delivery services. This study aims to understand home drug delivery service from the perspective of community pharmacists in Saudi Arabia. Also, the study investigates the obstacles that may limit the use of home drug delivery service. Methods: A cross-sectional self-reported survey was distributed from February 2021 to May 2021. Descriptive analysis of sociodemographic characteristics was conducted and presented. Frequencies and percentages were calculated for all variables. Results: A total of 965 community pharmacists were surveyed. Most of the pharmacists, (73.5%) were young, aged 23 to 34 years old. The vast majority of the participants, (93.6%), said that the service will improve drug adherence. The lack of required knowledge and skills among pharmacists could be the main obstacle to implement home drug delivery service (34%). A shortage in the number of community pharmacists was the second main obstacle (24%). Conclusion: Home delivery services in the future may largely replace the tradition of going in person to the pharmacy. There are obstacles that may limit the full use of the service like shortage in number of pharmacists and the lack of required training

Brucellar testicular abscess: The 17th case report and review of literature

Brucellosis is an endemic zoonotic disease caused by intracellular gram-negative coccobacilli called Brucella. This infectious disease may implicate many farm animals and is transmissible to exposed humans. Brucellosis is potentially life-threatening and may lead to granulomatous multi-organ involvement with tendency to chronicity and recurrence. The treatment of brucellosis requires combined and protracted antimicrobial therapies to eliminate the disease and to avoid its relapse. Genitourinary brucellosis is common among infected humans in endemic areas and is considered the second-most affected focal site, which commonly manifests as epididymo-orchitis. Testicular abscess, however, is an extremely rare complication of brucellosis. To the best of our knowledge, in the literature, there are to date only 16 previously published case reports, including 22 patients of brucellar testicular abscesses, emphasizing the extreme rarity of this condition. Most of these cases harbored small abscesses, which were treated conservatively using antibiotics therapy only, or with added drainage of the abscesses. Larger abscesses were reported to necessitate orchiectomy. In some cases, the abscesses were mimicking tumors, and surgeries for orchiectomy were done accordingly. A summary of the previously reported cases in the literature is presented. Here, we present the 17th case report of a 34-year-old man with a right-side huge multilocular brucellar testicular abscess apparently replacing the entire testicle, who was successfully treated with organ-sparing management by incision-drainage of the large abscess with antibiotics, to eventually preserve his testis. In conclusion, brucellosis should be considered among the differential diagnoses of any testicular swelling, especially in endemic areas. Drainage of brucellar testicular abscess with appropriate medical treatment is feasible and may preserve the testicle, even with large abscess apparently replacing the entire testicle

Career Readiness Among Saudi Pharmacy Students: Exploring the Need for and the Impact of Career Counseling Services

Purpose: Employers place emphasis on graduates’ work experience and interpersonal skills while academia mainly focuses on developing students’ learning ability. One proposed strategy is through career guidance by universities; however, supportive evidence is lacking. This study explored the career readiness of pharmacy students for the Saudi job market. It also examined the availability of career guidance services for pharmacy students and alumni in Saudi Arabia and the impact of such services on recipients’ career path choices and development of competencies. Subjects and Methods: This cross-sectional study utilized an online-based survey. Pharmacy students in the last three years of their program and recent graduates participated in the survey. The study used descriptive statistics to describe participants’ demographic data. Respondents were asked to rate aspects related to career readiness on a 5-point Likert scale, and their responses were reported as frequencies with percentages or means as appropriate. Comparisons between groups were made using t-test or one-way ANOVA as required. Results: A total of 576 responses were collected. About 25% of participants acknowledged the career guidance services provided at their pharmacy college, whereas the majority indicated that they have never reached out to a career counselor at their university (89.6%). The highest level of disagreement was noticed in impact of career guidance services on participants’ establishment of their CV/portfolio (50.7%). Using the work readiness scale, the lowest mean was seen in the social intelligence domain (3.64 ± 0.94). Conclusion: Although substantial proportion of students reported the presence of career guidance services in their university or college, very few stated that they had utilized such services. This could have impacted the students’ career readiness for the rapidly changing Saudi job market. Therefore, proper measures to advertise the availability of career guidance services in Saudi pharmacy schools have to be implemented

Spectrofluorometric quantitative analysis of aripiprazole based on quenching of natural derived carbon quantum dots in spiked human plasma

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

Factors Affecting Pharmacy Students’ Decision to Study in Pharmacy Colleges in Saudi Arabia: A Cross-Sectional Questionnaire-Based Analysis

(1) Background: Many factors may play a role in deciding to opt for pharmacy as a major. However, no previous studies have been conducted in Saudi Arabia to explore these factors. This study aims to identify the potential factors that prompted students to join the pharmacy program. (2) Methods: A cross-sectional questionnaire was distributed among undergraduate pharmacy students in Saudi Arabia, addressing areas such as reasons that encourage them to choose pharmacy as a major, and students’ socio-demographic characteristics. Descriptive statistics were used to describe the study variables, and a simple logistic regression analysis was performed to identify the potential factors. (3) Results: A total of 491 students completed the questionnaire. Around 40% of them had chosen to study pharmacy as their first choice. Only gender, current GPA, and reasons related to the pharmacy field were found to have a statistically significant association with students selecting pharmacy as their first choice. (4) Conclusions: This study shows that pharmacy students have a future-oriented outlook and selected pharmacy as their first choice because it will develop them professionally, financially, and intellectually. Educating high school students about the characteristic of pharmacy would help attract more talented students to the pharmacy carrier

Evaluate the Effectiveness of Outpatient Parenteral Antimicrobial Therapy (OPAT) Program in Saudi Arabia: A Retrospective Study

(1) Background: Outpatient parenteral antibiotic therapy (OPAT) is a well-established and cost-effective measure that improves the efficient use of healthcare resources and increases bed availability. Only limited published data is available to illustrate OPAT implementation and outcomes in Saudi Arabia. The main objective of this study was to evaluate the effectiveness of OPAT in a tertiary center in Saudi Arabia. (2) Methods: In this retrospective study, clinical charts of enrolled patients were reviewed in a tertiary care center from the initial month of November 2017 to March 2020. All admitted patients with a central line and who enrolled in the OPAT of the hospital during this study period were included. The primary outcome was the 30-days readmission rate of OPAT patients. Secondary outcomes were factors associated with OPAT failure. Descriptive analysis of the data was used to express the results. (3) Results: We enrolled 90 patients; 54 (60%) were male; the mean age was 55.16 (±17.7) years old. The mean duration of the antimicrobial treatment was 21.9 (+24.6) days. All patients completed the intended course of therapy. Ertapenem was the most frequently used antimicrobial (43%), followed by vancomycin (11.2%). Urinary tract infections (UTIs) are some of the most common bacterial infections in 25 patients (26.9%), followed by osteomyelitis in 16 patients (17.2%). Extended-spectrum beta-lactamase E.coli was the highest common isolated microorganism (44.9%), followed by methicillin-resistant Staphylococcus aureus MRSA (16.9%). The readmission to the hospital during therapy was required for 12 patients (13.3%). Shifting from hospital care to OPAT care resulted in cost savings of 18 million SAR in the overall assessment period and avoided a total of 1984 patient days of hospitalization. (4) Conclusion: The findings have shown that OPAT therapy was effective with minimum hospital readmissions and therapy complications. OPAT programs can reduce healthcare costs and should be integrated into practice
