Trends in prescription and cost of Sativex, a cannabinoid-based medicine, in treating patients with multiple sclerosis in England.

Aim: Cannabis-based medication has recently been made available in the NHS for reducing pain and spasticity in patients with multiple sclerosis (MS). The currently available preparation of Sativex (nabiximols) contains a combination of botanical cannabis extracts with cannabidiol (CBD) and tetrahydrocannabinol (THC) with almost equal amounts in addition to minor cannabinoids and terpenoids and is delivered via an oro-mucosal spray. The present study aims to examine the use and trends in prescribing cannabinoid-based Sativex to control pain in patients diagnosed with MS. Methods: Primary care prescribing data for cannabinoid-based Sativex (2013-2022) from the Prescription Cost Analysis were extracted and analysed. Linear regression analyses were performed to examine prescription trends and prescription costs (average change per year). Results: There was a general increasing trend in the number of prescriptions each year, from 4.42 items dispensed per 100,000 people in 2013 to 5.15 in 2022. Overall, prescription items for cannabinoid-based Sativex increased by 0.34% per year (95% CI:-3.98, 4.67, p = 0.860) on average between 2013 and 2022. On average, a 2.43% (95% CI: -5.78, 0.92, p = 0.133) increase per year was observed for the costs of cannabinoid-based Sativex from 2013 to 2022. Conclusion: The results suggested that cannabinoid-based Sativex should be considered an option due to its effectiveness, acceptable tolerance, and safety profile in the prescribing of Sativex.

Pharmacological interventions to improve sleep in people with Alzheimer's disease: a meta-analysis of randomized controlled trials.

INTRODUCTION: This systematic review and meta-analysis evaluates the evidence from randomized controlled trials (RCTs) involving pharmacological interventions for improving sleep in people with Alzheimer's disease (AD). METHODS: A systematic literature search in eight databases from January 2000 to July 2023 focusing on RCTs that compared a pharmacological intervention with a placebo for enhancing sleep in people with AD. The authors registered the study protocol at Prospero, followed the PRISMA guidelines, and produced the pooled estimates using random-effect or IVhet models. RESULTS: Eight different interventions and 29 different sleep outcomes were examined in 14 RCTs included in this review. Eszopiclone positively affected sleep efficiency, as did orexin antagonists. However, there was no difference when melatonin was used. The interventions demonstrated low discontinuation rates and a few adverse drug reactions. CONCLUSION: Although melatonin was the most investigated intervention, the evidence for its efficacy is inconclusive. On the other hand, trazodone and orexin receptor antagonists showed promising results; however, more RCTs are needed for definite answers.

A real-world exploration into clinical outcomes of direct oral anticoagulant therapy in people with chronic kidney disease: a large hospital-based study.

BACKGROUND: There is limited evidence to support definite clinical outcomes of direct oral anticoagulant (DOAC) therapy in chronic kidney disease (CKD). By identifying the important variables associated with clinical outcomes following DOAC administration in patients in different stages of CKD, this study aims to assess this evidence gap. METHODS: An anonymised dataset comprising 97,413 patients receiving DOAC therapy in a tertiary health setting was systematically extracted from the multidimensional electronic health records and prepared for analysis. Machine learning classifiers were applied to the prepared dataset to select the important features which informed covariate selection in multivariate logistic regression analysis. RESULTS: For both CKD and non-CKD DOAC users, features such as length of stay, treatment days, and age were ranked highest for relevance to adverse outcomes like death and stroke. Patients with Stage 3a CKD had significantly higher odds of ischaemic stroke (OR 2.45, 95% Cl: 2.10-2.86; p = 0.001) and lower odds of all-cause mortality (OR 0.87, 95% Cl: 0.79-0.95; p = 0.001) on apixaban therapy. In patients with CKD (Stage 5) receiving apixaban, the odds of death were significantly lowered (OR 0.28, 95% Cl: 0.14-0.58; p = 0.001), while the effect on ischaemic stroke was insignificant. CONCLUSIONS: A positive effect of DOAC therapy was observed in advanced CKD. Key factors influencing clinical outcomes following DOAC administration in patients in different stages of CKD were identified. These are crucial for designing more advanced studies to explore safer and more effective DOAC therapy for the population.

Impact of uricosurics on mortality outcomes in patients with COVID-19: a systematic review and meta-analysis of randomized controlled trials.

OBJECTIVES: To determine risks associated with uricosurics in COVID-19 patients. METHODS: A systematic review and meta-analysis was conducted by systematically searching electronic databases. KEY FINDINGS: The pooled analysis of the included trials revealed that the use of uricosurics was not associated with the risk of mortality (pooled odds ratio [OR] = 1.03, 95% confidence interval [CI]: 0.94-1.12). However, there is a potential mortality benefit associated with the use of ascorbic acid (pooled OR = 0.78, 95% CI: 0.65-0.94). CONCLUSIONS: The findings confirmed the safety of uricosurics in COVID-19 patients, despite their potential to cause uric acid excretion, which may possess antioxidant properties.

Measuring empathic behaviour among undergraduate dietetics students.

AIM: Empathic behaviour has a direct link to the positive clinical outcomes. Health professionals, which include dietitians, are increasingly expected to demonstrate the impact of their care on patient outcomes. To date, there is limited research exploring the empathic behaviour of dietetics students. METHODS: This cross-sectional study evaluated the psychometric properties of Jefferson Scale of Empathy-Healthcare Provider Student (JSE-HPS) and empathic behaviour of dietetics students. RESULTS: Undergraduate dietetics students from one private and two public universities in Malaysia participated (n = 455). Item and scale psychometric properties were examined using principal component analysis and differences in mean empathy scores for students were assessed across years of study and types of universities. A 3-factor solution emerged in the results, accounting for 26.76%, 10.75% and 6.3% of the variance. The JSE-HPS demonstrated good internal consistency (α = 0.83). Despite students enroled at public universities scoring higher mean empathy scores than students enroled at the private university, the difference was not significant. The only significant difference was between the empathy level of first and third year students (p = 0.033). CONCLUSION: As empathy underpins patient-centred management in the nutrition care process, it should be well integrated into curriculum delivery so that appropriate levels of empathy can be developed to prepare work-ready healthcare professionals.

Direct oral anticoagulants and the risk of adverse clinical outcomes among patients with different body weight categories: a large hospital-based study.

OBJECTIVE: Through predictable pharmacokinetics-including a convenient fixed-dose regimen, direct oral anticoagulants (DOACs) are preferred over previous treatments in anticoagulation for various indications. However, the association between higher body weight and the risk of adverse consequences is not well studied among DOAC users. We aim to explore the association of body weight and adverse clinical outcomes in DOAC users. METHODS: A total of 97,413 anonymised DOAC users in a tertiary care setting were identified following structured queries on the electronic health records (EHRs) to extract the feature-rich anonymised dataset. The prepared dataset was analysed, and the features identified with machine learning (ML) informed the adjustments of covariates in the multivariate regression analysis to examine the association. Kaplan-Meier analysis was performed to evaluate the mortality benefits of DOACs. RESULTS: Among DOAC users, the odds of adverse clinical outcomes, such as clinically relevant non-major bleeding (CRNMB), ischaemic stroke, all-cause mortality, and prolonged hospital stay, were lower in patients with overweight, obesity, or morbid obesity than in patients with normal body weight. The odds of ischaemic stroke (OR 0.42, 95% CI: 0.36-0.88, p = 0.001) and all-cause mortality (OR 0.87, 95% CI: 0.81-0.95, p = 0.001) were lower in patients with morbid obesity than in patients with normal body weight. In the Kaplan-Meier analysis, apixaban was associated with a significantly lower rate of mortality overall and in obesity and overweight subgroups than other DOACs (p < 0.001). However, rivaroxaban performed better than apixaban in the morbid obesity subgroup (p < 0.001). CONCLUSION: This study shows the positive effects of DOAC therapy on clinical outcomes, particularly in patients with high body weight. However, this still needs validation by further studies particularly among patients with morbid obesity.

Pharmacist-led interventions in optimising the use of oral anticoagulants in patients with atrial fibrillation in general practice in England: a retrospective observational study.

BACKGROUND: Oral anticoagulation (OAC) is the mainstay of treatment for the prevention of strokes in patients with atrial fibrillation (AF). Direct oral anticoagulants (DOACs) account for increasing OAC in patients with AF. However, prescribing DOACs for patients with established AF poses various challenges and general practice pharmacists may have an important role in supporting their management. AIM: To investigate the effectiveness of pharmacist-led interventions in general practice in optimising the use of OAC therapies in AF. DESIGN & SETTING: A retrospective observational study in general practices in Bradford. METHOD: The data were collected retrospectively from 1 November 2018-31 December 2019 using electronic health record data. The data were analysed: 1) to identify patients with AF not on OAC; 2) to describe inappropriate DOAC prescriptions; and 3) to calculate HAS-BLED scores. RESULTS: Overall, 76.3% (n = 470) of patients with AF received OAC therapy, and of these, 63.4% received DOACs. Pharmacist-led interventions increased DOAC prescribing by 6.0% (P = 0.03). Inappropriate DOAC use was identified in 24.5% of patients with AF, with underdosed and overdosed identified in 9.7% and 14.8%, respectively. Post-intervention, inappropriate prescribing was reduced to 1.7%. The mean HAS-BLED score decreased from 3.00 to 2.22 (P<0.01). Successful transition from vitamin K antagonist (VKA) therapy to DOACs was achieved in 25.7% of patients. CONCLUSION: Pharmacist-led interventions have successfully improved the use of OAC therapies in patients with AF, and effectively managed the bleeding risks and transition from VKA to DOAC therapy, in line with guidelines.

The effect of probiotics on the risk of mortality in patients with COVID-19: systematic review and meta-analysis of randomized trials.

Probiotics have been hypothesized to play a beneficial role in modulating immune responses and gut microbiota in various clinical settings. This systematic review and meta-analysis aimed to assess the effectiveness of probiotics in reducing all-cause mortality among patients diagnosed with COVID-19. We conducted a comprehensive search of the following databases: PubMed, Scopus, and Web of Science for published studies, and medRxiv, Research Square, and SSRN for preprints. The search spanned from the inception of these databases to April 4, 2023. We included studies that investigated the use of probiotics as an intervention and their impact on all-cause mortality in patients with COVID-19. A random-effects model meta-analysis was employed to estimate the pooled odds ratio, along with 95% confidence interval, to quantify the outcomes associated with probiotic use compared to other interventions. Our systematic review comprised six studies, encompassing a total of 642 patients. The meta-analysis, employing a random-effects model, demonstrated a statistically significant reduction in the risk of all-cause mortality when probiotics were administered to patients with COVID-19, compared to those not receiving probiotics (pooled odds ratio = 0.44; 95% confidence interval 0.24-0.82). In conclusion, evidence derived from randomized controlled trials (RCTs) indicates a survival benefit associated with the use of probiotics among COVID-19 patients. However, it is essential to exercise caution and await data from large-scale randomized trials to definitively confirm the mortality benefits of probiotics in this patient population.

Systematic review and meta-analysis of anti-CD20 treatments in patients with COVID-19: an assessment of severe illness and mortality outcomes.

BACKGROUND: The use of anti-CD20 monoclonal antibodies, such as rituximab and ocrelizumab, has emerged as a matter of concern, in patients with coronavirus disease 2019 (COVID-19). OBJECTIVE: We aimed to summarize the overall evidence on the pre-admission/pre-diagnosis use of anti-CD20 among patients with COVID-19 with regards to mortality and severe illness outcomes. METHODS: A systematic literature search with no language restriction was performed in electronic databases, including PubMed, Google Scholar, Scopus, and preprint servers (medRxiv, Research Square, SSRN), to identify eligible studies published up to June 13, 2023. The outcomes of interest were the development of severe illness and all-cause mortality. A random-effects model was used to estimate the pooled odds ratio for outcomes of interest using anti-CD20 monoclonal antibodies relative to non-use of anti-CD20 monoclonal antibodies, at 95% confidence intervals. RESULTS: Our systematic review and meta-analysis revealed significantly increased odds for development of severe illness (pooled odds ratio 2.95; 95% confidence interval 2.30, 3.78; n = 534,349) and significantly increased odds for mortality (pooled odds ratio 2.14; 95% confidence interval 1.37, 3.35; n = 333,462) with the use of anti-CD20 monoclonal antibodies, relative to non-use of anti-CD20 monoclonal antibodies, in patients with COVID-19. CONCLUSION: Healthcare practitioners should exercise caution when prescribing these anti-CD20 monoclonal antibodies during the COVID-19 pandemic to patients who are indicated for these agents, particularly those with underlying conditions like multiple sclerosis or rheumatoid arthritis.
