Abstract

Abstract Heart failure (HF) is a global epidemic with a prevalence of over 64.3 million cases worldwide. Several factors account for the increase in the prevalence of HF. The most significant factor is the growing population of older adults. Other factors include improved treatment and survival after myocardial infarction, poorly controlled hypertension (HTN), and diabetes mellitus (DM). As a modifiable construct, perceived control can be improved to promote healthier lifestyle choices, such as self-care, and consequently better health outcomes. A person’s perception of control is their conviction that they have the power to deal with adverse circumstances, like receiving an HF diagnosis, and produce favorable results, such as an improvement in symptom status. The objective of this study was to evaluate the factors influencing perceived control attitudes among patients with heart failure in Oman. In this sample of HF patients (N = 180), the mean perceived control attitude was 16.97 ± 2.25. Certain factors had higher effects than others. For example, females (p = 0.006), old age (p

Abstract

Background: To stay abreast of the best international practices, the Arab Gulf countries have ratified the United Nations Convention on the Rights of the Child Treaty, which includes clauses on safeguarding the well-being of children against child abuse and neglect. The enactment of laws, policies, and facilities designed to protect the rights of the child has not yet been studied to determine whether it leads to appropriate legal dispositions against perpetrators of child sexual abuse (CSA) in Oman. Aims: This study has been launched to address two interrelated objectives; (i) describe the characteristics of CSA victims and perpetrators and (ii) examine factors associated with medicolegal findings and judicial results for CSA complainants in Oman. Methods: Data come from a retrospective survey that covered one year from January 2017 to December 2017. Data from participants who met the study criteria were drawn from statistics published by the Oman Public Prosecution. The study was designed to obtain sociodemographic characteristics of victims and perpetrators of CSA, the types of prevalent cases of CSA, whether CSA was the result of family or extrafamilial encounters, and the characteristics of medical findings and legal results. Result: During the designated period, 269 victims and 269 defendants were identified. Most of the victims were boys (55.8 %), and their ages ranged from 9 to 15 years (mean age 12 years). Among the perpetrators, all were men, with ages ranging between 20 and 40 years (mean age 28.3 years). The vast majority (96.7 %) of reported cases were of extrafamilial type. The identified types of CSA constituted inappropriate sexual behavior towards children (63 %), followed by sodomization (26 %) and vaginal coitus (7.1 %). The factors that explained the results in favour of the victims in the medicolegal findings included the female sex of the victim (AOR = 2.78, 95%CI = 1.01–7.87), and the ages of the victim between 8 and 12 years (AOR = 4.29, 95 % CI = 1.51–12.16). Among the cases that were tried in court, 76 % were convicted and sentenced to an average of 30 months in correctional facilities. Factors associated with the conviction of the perpetrator were victims' ages between 13 and 17 years (AOR = 3.45, 95 % CI = 1.22 to 9.79), the type of abuse was sodomization (AOR = 1.95, 95%CI = 1.08–6.78), and cases that included positive forensic results (AOR = 2.66, 95 % CI = 1.23 to 8.45). Discussion: To date, studies on medical-legal and judicial outcomes of CSA in developing countries have received little attention. The present sentinel study lays the foundation for future studies using the robust methodology required to further scrutinize the medicolegal findings and judicial results of CSA in similar regions of the Middle East. The present findings also suggest that the CSA trends in Oman tend to echo those reported from developed countries, but there are also culture-specific factors that shape reporting, as well as medico-legal and judicial outcomes.

Abstract

Objectives:To evaluate the prognostic value (total mortality + repeated hospitalization for heart failure (HF)) of ultrasound diagnostic methods in patients with acute decompensated HF (ADHF). Methods: The subjects were patients with chronic HF, who were hospitalized for ADHF. Using ultrasound methods—lung ultrasound, ultrasound assessment of hepatic venous congestion as per the venous excess ultrasound (VExUS) protocol, and indirect elastometry—we assessed the number of B-lines, hepatic venous congestion, and liver density of the patients. Clinical outcomes were assessed using a structured telephone survey method at 1, 3, 6, and 12 months after discharge. Combined overall mortality and readmission rates associated with HF were assessed. Threshold values for different methods for detecting congestion were set as follows: the number of B-lines in ultrasound data > 5; liver density > 6.2 kPa. Results: The subjects were 207 patients (54.1% male; mean age = 70.7 ± 12.8 years). A total of 63 (30.4%) endpoints and 23 (11.1%) deaths were detected within 364 days (IQR = 197–365). Liver density > 6.2 kPa had a hazard ratio (HR) of 1.9 ( 95% CI: 1.0–3.3; p =0.029). Hepatic venous congestion (VExUS protocol) had HR of 2.8 (95% CI: 1.3–5.7; p =0.004). There was a significant increase in the risk of overall prognostic value in the presence of congestion, identified by liver fibroelastometry + lung ultrasound (HR = 10.5, 95% CI: 2.3–46.2; p =0.002). The ultrasound assessment of hepatic venous congestion (VExUS + lung ultrasound protocol) yielded HR of 16.7 (95% CI: 3.9–70.7; p < 0.001). For all three methods combined, the overall HR was 40.1 (95% CI: 6.6–243.1; p < 0.001). Conclusions: A combination of ultrasound diagnostic methods that include the number of B-lines, presence of hepatic venous congestion according to the VExUS protocol, and liver density according to indirect elastometry at discharge may have an independent prognostic value for patients with ADHF.

15. An agent-based variogram modeller : investigating intelligent, distributed-component Geographical Information Systems

Author

Al Zakwani, A.

Abstract

Geo-Information Science (GIScience) is the field of study that addresses substantive questions concerning the handling, analysis and visualisation of spatial data. Geo-Information Systems (GIS), including software, data acquisition and organisational arrangements, are the key technologies underpinning GIScience. A GIS is normally tailored to the service it is supposed to perform. However, there is often the need to do a function that might not be supported by the GIS tool being used. The normal solution in these circumstances is to go out and look for another tool that can do the service, and often an expert to use that tool. This is expensive, time consuming and certainly stressful to the geographical data analyses. On the other hand, GIS is often used in conjunction with other technologies to form a geocomputational environment. One of the complex tools in geocomputation is geostatistics. One of its functions is to provide the means to determine the extent of spatial dependencies within geographical data and processes. Spatial datasets are often large and complex. Currently Agent system are being integrated into GIS to offer flexibility and allow better data analysis. The theis will look into the current application of Agents in within the GIS community, determine if they are used to representing data, process or act a service. The thesis looks into proving the applicability of an agent-oriented paradigm as a service based GIS, having the possibility of providing greater interoperability and reducing resource requirements (human and tools). In particular, analysis was undertaken to determine the need to introduce enhanced features to agents, in order to maximise their effectiveness in GIS. This was achieved by addressing the software agent complexity in design and implementation for the GIS environment and by suggesting possible solutions to encountered problems. The software agent characteristics and features (which include the dynamic binding of plans to software agents in order to tackle the levels of complexity and range of contexts) were examined, as well as discussing current GIScience and the applications of agent technology to GIS, agents as entities, objects and processes. These concepts and their functionalities to GIS are then analysed and discussed. The extent of agent functionality, analysis of the gaps and the use these technologies to express a distributed service providing an agent-based GIS framework is then presented. Thus, a general agent-based framework for GIS and a novel agent-based architecture for a specific part of GIS, the variogram, to examine the applicability of the agent- oriented paradigm to GIS, was devised. An examination of the current mechanisms for constructing variograms, underlying processes and functions was undertaken, then these processes were embedded into a novel agent architecture for GIS. Once the successful software agent implementation had been achieved, the corresponding tool was tested and validated - internally for code errors and externally to determine its functional requirements and whether it enhances the GIS process of dealing with data. Thereafter, its compared with other known service based GIS agents and its advantages and disadvantages analysed.

Abstract

Abstract Background Cardiovascular diseases are responsible for a significant proportion of mortalities worldwide. Elderly patients are the most affected by cardiovascular diseases, and because of factors such as polypharmacy, multimorbidity, and age-related changes in drug availability and metabolism, they are highly susceptible to the occurrence of drug–drug interactions. Drug–drug interactions are among the many drug-related problems leading to negative outcomes among inpatients and outpatients. Thus, it is important to investigate the prevalence, involved drugs, and factors related to potential drug–drug interactions (pDDIs) to properly optimize pharmacotherapy regimens for these patients. Objective We aimed to determine the prevalence of pDDIs, drugs most frequently implicated, and significant predictors associated with these interactions among hospitalized patients in the Cardiology Unit at Sultan Qaboos University Hospital in Muscat, Oman. Methods This retrospective cross-sectional study included 215 patients. Micromedex Drug-Reax® was used to identify pDDIs. Data extracted from patients’ medical records were collected and analyzed. Univariable and multivariable linear regression was applied to determine the predictors associated with the observed pDDIs. Results A total of 2057 pDDIs were identified, with a median of nine (5–12) pDDIs per patient. Patients with at least one pDDI accounted for 97.2% of all the included patients. The majority of pDDIs were of major severity (52.6%), fair level of documentation (45.5%), and pharmacodynamic basis (55.9%). Potential drug–drug interactions between atorvastatin and clopidogrel were the most frequently observed (9%). Of all the detected pDDIs, around 79.6% of them included at least one antiplatelet drug. Having diabetes mellitus as a comorbidity (B = 2.564, p < 0.001) and the number of drugs taken during the hospitalization period (B = 0.562, p < 0.001) were factors positively associated with the frequency of pDDIs. Conclusions Potential drug–drug interactions were highly prevalent among hospitalized cardiac patients at Sultan Qaboos University Hospital, Muscat, Oman. Patients having diabetes as a comorbidity and with a high number of administered drugs were at a higher risk of an increased number of pDDIs.

18. Enhancing Omani EFL learning environments : a participatory action research study into the application and development of an appropriate SOLE pedagogy

Author

Al Zakwani, Malik Hamed Saif

Abstract

This researcher explored English as a Foreign Language (EFL) students' experiences in learning English using Self-Organized Learning Environments (SOLEs) within the context of their English foundation year in a college setting in Oman. Three purposes guided this research: 1. to explore Omani EFL students' experience of and orientation toward SOLEs, 2. to investigate whether SOLE pedagogy is able to facilitate an effective English language learning environment for Omani students and 3. to theorize a model for effective and impactful SOLE adoption within an EFL learning context. Most of the previous studies on SOLEs have only examined students' achievements in SOLEs but have not explored participants' views, emotions and criticism of the new learning environment, a considerable omission from the research since SOLEs purport to be precisely a learning environment that is able to be responsive to and malleable and mutable by the participants themselves. Using a participatory action research design, data sources included a series of diaries, semi-structured interviews, focus groups and the researcher's field notes. Interaction between the researcher and participants and among participants themselves helped to ensure the rigour of this research. Throughout the research, participants were involved in expressing their ideas and thoughts about SOLEs and in decision-making as they were offered numerous opportunities to continually reflect upon and refine their thoughts. The results indicated that SOLEs can be a successful EFL pedagogical approach but any SOLE utilised for this purpose has to undergo structural changes which include the nature and role of big questions and the role of teachers. Results indicated that teachers should take more roles, such as, supervise, monitor, and adopt different behaviours, such as remaining in the classroom, supporting, encouraging and grouping students when appropriate. Results also indicated that big questions should not be the only questions asked. Some strengths of SOLEs that were indicated by the results include the suitability of SOLEs for tertiary level education, boosting learning and cooperation, giving students some freedom, creating the possibility for student autonomy, empowering students, allowing the use of the Internet, suitability for different learning styles, and motivating students in ways hitherto iii unacknowledged by teachers. These results together form the contribution and significance of this empirical study. This empirical study assists in understanding the construction of an effective English language learning environment in an under-researched international context. It also contributes to previous and ongoing studies that investigate SOLEs in different contexts and fields to explore and examine their impact on students' experiences. This study concludes with implications for future studies that include the investigation of SOLEs in relation to student retention and achievement in language learning courses.

Abstract

This study explored parents’ attitudes towards vaccinating their children against COVID-19 and the rate of vaccine hesitancy in Oman. A cross-sectional, online, self-administered questionnaire, previously validated and administered between June 2021 and May 2022, was used. The questionnaire consisted of nine items. Parents of children younger than 12 years were eligible for participation. A total of 384 participants, including 207 males (54%), completed the questionnaire, resulting in an 86% response rate (384/447). The results showed that 69% of participants were hesitant to vaccinate their children aged 1–11 years. In parents of children aged 1–4 years, vaccination status was significantly associated with vaccine hesitancy (odds ratio [OR], 0.116; 95% confidence interval [CI], 0.044–0.306; p = 0.001). Furthermore, after multivariable analysis, compared to the fathers, mothers were significantly less likely to be associated with vaccine hesitancy (OR, 0.451; 95% CI, 0.240–0.848; p = 0.013).

Abstract

This study aimed to evaluate the clinical outcomes of patients with acute heart failure (AHF) stratified by mitral regurgitation (MR) in the Arabian Gulf. Patients from the Gulf CARE registry were identified from 47 hospitals in seven Arabian Gulf countries (Yemen, Oman, Kuwait, Qatar, Bahrain, the United Arab Emirates, and Saudi Arabia) from February to November 2012. The cohort was stratified into two groups based on the presence of MR. Univariable and multivariable statistical analyses were performed. The population cohort included 5005 consecutive patients presenting with AHF, of whom 1491 (29.8 %) had concomitant MR. The mean age of patients with AHF and concomitant MR was 59.2 ± 14.9 years, and 63.1 % (n = 2886) were male. A total of 58.6 % (n = 2683) had heart failure (HF) with reduced ejection fraction (EF) (HFrEF), 21.0 % (n = 961) had HF with mildly reduced EF (HFmrEF), and 20.4 % (n = 932) had HF with preserved EF (HFpEF). Patients with MR had a lower haemoglobin (Hb) level (12.4 vs. 12.7 g/dL; p

Abstract

Objectives: Patient-centered clinical pharmacists’ activities play a major role in improving clinical outcomes by optimizing the efficacy of drug therapies and minimizing associated toxicities during hospitalization, at the transition of care, and upon discharge. We aimed to compare the impact of comprehensive versus partial clinical pharmacists-driven bundled of care services on the rate of 90-day hospital readmissions and emergency department (ED) visits. Methods: This retrospective study included all admitted patients who received a comprehensive or partial bundle of clinical pharmacy services (medication history, interventions, counseling, and discharge prescription review) from 1 January 2021 to 30 June 2021 at Sultan Qaboos University Hospital. The comprehensive bundle of care included the four services, while the partial bundle of care included one, two, or three services only. Analyses were performed using univariate and multivariate statistical techniques. Results: The study included 430 patients with a mean age of 56.0±21.0 years, and 43.7% (n = 188) were male. Of the patients, 12.1% (n = 52) received a comprehensive bundle of care. Compared with the partial bundle of care group, the comprehensive bundle of care group had significantly more patients with diabetes (65.4% vs. 42.9%; p =0.002), ≥ 3 comorbidities (50.0% vs. 29.4%; p =0.003), and polypharmacy (≥ 5 medications) (73.1% vs. 46.0%; p < 0.001). The comprehensive bundle of care group was significantly associated with a lower 90-day readmission rate (adjusted odds ratio (aOR) = 0.27, 95% CI: 0.90–0.82; p =0.021) but not with ED visits (aOR = 0.57, 95% CI: 0.13–2.57; p =0.461). Conclusions: This study demonstrated a significant reduction in the 90-day readmission rate for patients on a comprehensive bundle of care but not ED visits. These findings emphasize the importance of the comprehensive services provided by clinical pharmacists on the healthcare resources use and clinical outcomes.

Abstract

Objectives: The Rajan’s heart failure (R-hf) score was proposed to aid risk stratification in heart failure patients. The aim of this study was to validate R-hf risk score in patients with acute decompensated heart failure. Methods: R-hf risk score is derived from the product estimated glomerular filtration rate (mL/min), left ventricular ejection fraction (%), and hemoglobin levels (g/dL) divided by N-terminal pro-brain natriuretic peptide (pg/mL). This was a multinational, multicenter, prospective registry of heart failure from seven countries in the Middle East. Univariable and multivariable logistic regression was applied. Results: A total of 776 patients (mean age = 62.0±14.0 years, 62.4% males; mean left ventricular ejection fraction = 33.0±14.0%) were included. Of these, 459 (59.1%) presented with acute decompensated chronic heart failure. The R-hf risk score group (≤ 5) was marginally associated with a higher risk of all-cause cumulative mortality at three months (adjusted odds ratio (aOR) = 4.28; 95% CI: 0.90–20.30; p =0.067) and significantly at 12 months (aOR = 3.84; 95% CI: 1.23–12.00; p =0.021) when compared to those with the highest R score group (≥ 50). Conclusions: Lower R-hf risk scores are associated with increased risk of all-cause cumulative mortality at three and 12 months.

Abstract

Chronic kidney disease (CKD) is a global health challenge, with a reported prevalence of around 10%. Prescribing for patients receiving hemodialysis (HD) is challenging and complicated by polypharmacy, comorbidities, and changes in clearance of medications. The aim of this study was to evaluate antibiotics utilization patterns and dosage appropriateness in patients receiving HD at a tertiary hospital. A retrospective study was carried on 287 adult inpatients, who received HD and at least one antibiotic in a tertiary hospital in Oman. Data were extracted using the hospital’s electronic patient information system. Dosage appropriateness was assessed by identifying the dosage and frequency of prescribed antibiotics and comparing them with international guidelines. The main outcome measures were antibiotics utilization patterns and dosing inappropriateness. The most commonly prescribed parenteral antibiotic was piperacillin + tazobactam (20%), while the most common prescribed oral antibiotic was azithromycin (41.7%). For prophylaxis, cefazolin (54.6%) was the main antibiotic prescribed. The most commonly used antibiotic for external use was mupirocin ointment (38.5%). The overall dosing inappropriateness was 29.5%. Vancomycin was the most common parenteral antibiotic subjected to dosing inappropriateness (19.8%). However, trimethoprim + sulfamethoxazole was more inappropriately prescribed among the oral route (28.6%).In conclusion, the most utilized antibiotic was piperacillin + tazobactam followed by vancomycin. The study reported some inappropriate dosing of antibiotics. Such a study opens the door for the establishment of local guidelines for the improved practice of antibiotics use in HD patients.

Abstract

Summary: Background: Arterial stiffening is central to the vascular ageing process and a powerful predictor and cause of diverse vascular pathologies and mortality. We investigated age and sex trajectories, regional differences, and global reference values of arterial stiffness as assessed by pulse wave velocity (PWV). Methods: Measurements of brachial-ankle or carotid-femoral PWV (baPWV or cfPWV) in generally healthy participants published in three electronic databases between database inception and August 24th, 2020 were included, either as individual participant-level or summary data received from collaborators (n = 248,196) or by extraction from published reports (n = 274,629). Quality was appraised using the Joanna Briggs Instrument. Variation in PWV was estimated using mixed-effects meta-regression and Generalized Additive Models for Location, Scale, and Shape. Findings: The search yielded 8920 studies, and 167 studies with 509,743 participants from 34 countries were included. PWV depended on age, sex, and country. Global age-standardised means were 12.5 m/s (95% confidence interval: 12.1–12.8 m/s) for baPWV and 7.45 m/s (95% CI: 7.11–7.79 m/s) for cfPWV. Males had higher global levels than females of 0.77 m/s for baPWV (95% CI: 0.75–0.78 m/s) and 0.35 m/s for cfPWV (95% CI: 0.33–0.37 m/s), but sex differences in baPWV diminished with advancing age. Compared to Europe, baPWV was substantially higher in the Asian region (+1.83 m/s, P = 0.0014), whereas cfPWV was higher in the African region (+0.41 m/s, P

Abstract

Antimicrobial resistance (AMR), a serious global public health challenge, may have accelerated development during the COVID-19 pandemic because antibiotics were prescribed for COVID-19. This study aimed to assess antibiotics use before and during the pandemic and correlate the results with the rate of resistant microorganisms detected in hospitalized patients during the study period. This single-center study looked retrospectively at four years of data (2018–2021) from Royal Hospital, Muscat, which is the biggest hospital in Oman with approximately 60,000 hospital admissions yearly. The consumption rate of ceftriaxone, piperacillin tazobactam, meropenem, and vancomycin was presented as the antibiotic consumption index, the ratio of defined daily dose (DDD) per 100 bed days. Analyses were performed using the nonparametric test for trend across the study period. Correlation between antibiotic consumption indexes and the isolated microorganisms in the four-year study period was performed using Spearman’s rank correlation coefficient. We compared data from the pre-COVID-19 to the COVID-19 period. Though more patients were admitted pre-COVID-19 (132,828 versus 119,191 during COVID-19), more antibiotics were consumed during the pandemic (7350 versus 7915); vancomycin and ceftriaxone had higher consumption during than before the pandemic (p-values 0.001 and 0.036, respectively). Vancomycin-resistant Enterococcus (VRE) and Candida auris were detected more during the COVID-19 period with p-values of 0.026 and 0.004, respectively. Carbapenem-resistant Enterobacterales (CRE), vancomycin-resistant Enterococcus spp., and C. auris were detected more often during the pandemic with p-values of 0.011, 0.002, and 0.03, respectively. Significant positive correlations between antibiotic consumption and drug-resistant isolates were noted. This study confirms that the overuse of antibiotics triggers the development of bacterial resistance; our results emphasize the importance of antibiotic control.

Abstract

Objectives: This study sought to determine whether early prone positioning of patients with moderate to severe COVID-19-related acute respiratory distress syndrome (ARDS) lowers the mortality rate. Methods: We conducted a retrospective study using data from intensive care units of two tertiary centers in Oman. Adult patients with moderate to severe COVID-19-related ARDS with a PaO2/FiO2 ratio < 150 on FiO2 of 60% or more and a positive end-expiratory pressure of at least 8 cm H2O who were admitted between 1 May 2020 and 31 October 2020 were selected as participants. All patients were intubated and subjected to mechanical ventilation within 48 hours of admission and placed in either prone or supine position. Mortality was measured and compared between the patients from the two groups. Results: A total of 235 patients were included (120 in the prone group and 115 in the supine group). There were no significant differences in mortality (48.3% vs. 47.8%; p =0.938) and discharge rates (50.8% vs. 51.3%; p =0.942) between the prone and supine groups, respectively. Conclusions: Early prone positioning of patients with COVID-19-related ARDS does not result in a significant reduction in mortality.

Abstract

Objectives: Initial reports indicate a high incidence of abnormal aspartate aminotransferase (AST) and alanine aminotransferase (ALT) levels in patients with COVID-19 and possible association with acute kidney injury (AKI). We aimed to investigate clinical features of elevated transaminases on admission, its association with AKI, and outcomes in patients with COVID-19. Methods: A retrospective analysis of the registered data of hospitalized patients with laboratory-confirmed COVID-19 and assessment of the AST and ALT was performed. Multinomial logistic regression was used to determine factors associated with community-acquired AKI (CA-AKI) and hospital-acquired AKI (HA-AKI). Results: The subjects comprised 828 patients (mean age = 65.0±16.0 years; 51.4% male). Hypertension was present in 70.3% of patients, diabetes mellitus in 26.0%, and chronic kidney disease in 8.5%. In-hospital mortality was 21.0%. At admission, only 41.5% of patients had hypertransaminasemia. Patients with elevated transaminases at admission were younger, had higher levels of inflammatory markers and D-dimer, and poorer outcomes. The AKI incidence in the study population was 27.1%. Patients with hypertransaminasemia were more likely to develop AKI (33.5% vs. 23.3%, p =0.003). Patients with predominantly elevated AST (compared to elevated ALT) were more likely to have adverse outcomes. Multinomial logistic regression found that hypertension, chronic kidney disease, elevated AST, and hematuria were associated with CA-AKI. Meanwhile, age > 65 years, hypertension, malignancy, elevated AST, and hematuria were predictors of HA-AKI. Conclusions: Elevated transaminases on admission were associated with AKI and poor outcomes. Patients with elevated AST were more likely to have adverse outcomes. Elevated AST on admission was associated with CA-AKI and was a predictor of HA-AKI.

Abstract

This study aimed to determine the stability of refrigerated analytes of iMg concentration at different time intervals and to establish iMg reference range in a cohort of healthy Omani volunteers (≥18 years). The concentrations of iMg were measured using the direct ion-selective electrode technique. Pearson’s and Lin’s concordance correlation coefficients along with the Bland–Altman plot were used to assess the levels of agreement between iMg concentrations of fresh and refrigerated blood samples at different time intervals. The study included 167 volunteers (51% females) with a median age of 21 (range: 20–25) years. The median, 2.5th, and 97.5th percentiles for fresh iMg reference ranges were 0.55, 0.47, and 0.68 mmol/L, respectively. The overall agreement between the fresh and refrigerated iMg concentrations was poor (rho-c = 0.51; p < 0.001). However, according to Altman’s definition, iMg concentrations of the refrigerated samples for a period of ≤1 h had an excellent correlation with the fresh iMg concentrations (Lin’s rho-c = 0.80), with a small average bias difference of 0.009 (95%CI; −0.025–0.043). A cut-off refrigeration period within ≤1 h at 2–8 °C can be considered an alternate time frame for the gold standard measurement (fresh or within 0.5 h).

Abstract

Abstract Background The ACR 1997, SLICC 2012 and EULAR/ACR 2019 classification criteria were validated based on adult patients. To date, there are no classification criteria specific for children with SLE. The aim of the study is to compare the performance characteristics among the three SLE classification criteria (ACR-1997, SLICC-2012 and EULAR/ACR-2019) in childhood onset SLE (cSLE) cohort of Arab ethnicity from Oman. Methods We conducted a retrospective multicenter study in Oman of cSLE patients as cases and patients with other rheumatic disease with a positive ANA titer as controls. The cSLE cases recruited were children diagnosed with SLE before 13 years of age. Data was retrospectively collected to establish the ACR-1997, SLICC-2012 and EULAR/ACR-2019 criteria fulfilled at first visit, first year follow up and last follow up. Results Study population included 113 cSLE cases (mean age at diagnosis of 7.3 ± 3.4 years with disease duration of 6.1 ± 4.6 years) and 51 controls (mean age at diagnosis 5.0 ± 3.4 with disease duration 5.7 ± 3.9). The cSLE cases had higher frequency of familial SLE than controls (38% vs 7.8%; p

Abstract

Objective: To evaluate the clinical and financial impact of clinical pharmacists’ interventions (CPIs) on antimicrobial use at a 500-bed multidisciplinary tertiary care hospital in Oman. Methods: A retrospective analysis of CPIs related to antimicrobials use at Sultan Qaboos University Hospital (SQUH) from January to December 2018. Interventions were recorded using an electronic CPI form and were reviewed by two independent CPs. Data on the type and clinical significance of the interventions were extracted. Cost analysis was done using a previously defined cost avoidance model in addition to direct cost reduction estimation. Descriptive data were used to describe the results. Results: In 2018, 26% of CPIs were related to antimicrobial use, with more than 60% of these interventions done on intensive care unit patients. The most common intervention type was adjusting the dosing regimen (42% of the total interventions), followed by deletion of the antimicrobial order in 34% of the cases. The most common clinical impact of CPIs was improving efficacy in 45% of the interventions, followed by preventing unnecessary exposure to the antimicrobials in around 30% of the interventions. The interventions were of major significance in 64% of the cases. This translated into a projected net cost saving of approximately $200,000 USD/year. Conclusions: CPs interventions on antimicrobial use had a positive impact on both the clinical and financial outcomes.

O. Box 35 Al Khoud, Muscat, 123, OmanEmail zaabi@squ.edu.omIntroduction: The diuretic agent furosemide (FUR, 25 and 50 mg/kg) has been shown in a single report to act as an anti-stressor agent in two models of acute stress in mice, viz. electric foot–shock stress and immobilization (IMS). The present work aimed to investigate the possible anti-stressor action of FUR on two models of acute stress in mice, cold-water stress (CWS) and IMS, and tried to determine whether gender has any impact on the effect of FUR.Methods: FUR (40 mg/kg) was injected intraperitoneally, and after 30 minutes, mice were subjected to CWS (4°C for three minutes) or IMS (fixing movement for two and a half hrs using adhesive tape). Motor and exploratory activities, neuromuscular coordination, and thermal nociception were then tested. Blood was collected from the mice and used to measure the concentrations of three stress hormones (corticosterone, epinephrine and prolactin).Results: Mice subjected to CWS and IMS had significantly reduced motor and exploratory activities, neuromuscular coordination, and increased nociception. CWS and IMS also significantly increased the plasma concentrations of the three hormones. FUR pretreatment significantly mitigated these stress-induced hormonal changes. There was no significant sex difference when CWS or IMS was applied.Discussion: IMS and CWS stimuli in male and female mice caused significant elevations in the plasma concentrations of corticosterone, epinephrine, and prolactin, accompanied by a significant reduction of motor and exploratory activities, neuromuscular coordination, and thermal nociception. There were no sex differences when IMS was applied. In stressed mice, prior administration of FUR (40 mg/kg) significantly decreased the concentrations of stress hormones, and this effect significantly mitigated the stress-induced behavioural and motor changes.Keywords: furosemide, immobilization stress, cold-water stress, corticosterone, prolactin, epinephrine
