Many medicines have anticholinergic properties, which have previously been correlated with a range of adverse effects, including cognitive impairment, hallucinations and delirium. These effects are potentially of concern for people with dementia. This systematic review investigated the effect of anticholinergic medicines on the health outcomes of people with pre-existing dementia. Embase, Medline and the Cochrane Library were searched from January 2000 to January 2021. Studies were included if they matched the following criteria: (1) the intervention involved anticholinergic medications; (2) the study was conducted in people with pre-existing dementia; (3) there was at least one comparator group; and (4) the outcome of interest was clinically measurable. A total of 14 studies met the inclusion criteria. Most studies used an anticholinergic burden scale to measure anticholinergic exposure. Five high-quality studies consistently identified a strong association between anticholinergic medications and all-cause mortality. Anticholinergics were also found to be associated with longer hospital length of stay in three studies. Inconsistent findings were reported for cognitive function (in 4 studies) and neuropsychiatric functions (in 2 studies). In single studies, anticholinergic medications were associated with the composite outcome of stroke and mortality, pneumonia, delirium, poor physical performance, reduced health-related quality of life and treatment modifications due to reduced treatment response or symptom exacerbation. While the evidence suggests that anticholinergic medication use for people with dementia has a strong association with all-cause mortality, the association with cognitive and other clinical outcomes remains uncertain. Hence, further studies are needed to substantiate the evidence for other outcomes.

Review
The prevalence of obesity has increased substantially over the last several decades and several environmental factors have accelerated this trend. Poly-methoxy flavones (PMFs) exist abundantly in the peels of citrus, and their biological activities have been broadly examined in recent years. Several studies have examined the effects of PMFs on obesity and its-related diseases. This systematic review conducted to focus on the effect of PMFs on obesity and its related conditions management. The PubMed, Google Scholar, Scopus, and Science Direct databases were searched for relevant studies published before November 2020. Out of 1,615 records screened, 16 studies met the study criteria. The range of dosage of PMFs was varied from 10 to 200 mg/kg (5-26 weeks) and 1-100 μmol (2h-8 days) across selected animal and studies, respectively. The literature reviewed shows that PMFs modulate several biological processes associated with obesity such as lipid and glucose metabolism, inflammation, energy balance, and oxidative stress by different mechanisms. All of the animal studies showed significant positive effects of PMFs on obesity by reducing body weight (e.g. reduced weight gain by 21.04%), insulin resistance, energy expenditure, inhibiting lipogenesis and reduced blood lipids (e.g. reduced total cholesterol by 23.10%, TG by 44.35% and LDL by 34.41%). The results of the reviewed studies have revealed that treatment with PMFs significantly inhibits lipid accumulation in adipocytes (e.g. reduced lipid accumulation by 55-60%) and 3T3-L1 pre-adipocyte differentiation as well by decreasing the expression of PPARγ and C/EBPα and also reduces the number and size of fat cells and reduced TG content in adipocytes by 45.67% and 23.10% and 16.08% for nobiletin, tangeretin and hesperetin, respectively. Although current evidence supports the use of PMFs as a complementary treatment in obesity, future research is needed to validate this promising treatment modality.

Review
BACKGROUND
Black Americans have a disproportionately increased risk of diabetes, hypertension, and kidney disease, and higher associated morbidity, mortality, and hospitalization rates than their White peers. Structural racism amplifies these disparities, and negatively impacts self-care including medication adherence, critical to chronic disease management. Systematic evidence of successful interventions to improve medication adherence in Black patients with diabetes, hypertension, and kidney disease is lacking. Knowledge of the impact of therapeutic alliance, ie, the unique relationship between patients and providers, which optimizes outcomes especially for minority populations, is unclear. The role and application of behavioral theories in successful development of medication adherence interventions specific to this context also remains unclear.
OBJECTIVE
To evaluate the existing evidence on the salience of a therapeutic alliance in effective interventions to improve medication adherence in Black patients with diabetes, hypertension, or kidney disease.
DATA SOURCES
Medline (via PubMed), EMBASE (OvidSP), Cumulative Index of Nursing and Allied Health Literature (CINAHL) (EBSCOhost), and PsycINFO (ProQuest) databases.
REVIEW METHODS
Only randomized clinical trials and pre/post intervention studies published in English between 2009 and 2022 with a proportion of Black patients greater than 25% were included. Narrative synthesis was done.
RESULTS
Eleven intervention studies met the study criteria and eight of those studies had all-Black samples. Medication adherence outcome measures were heterogenous. Five out of six studies which effectively improved medication adherence, incorporated therapeutic alliance. Seven studies informed by behavioral theories led to significant improvement in medication adherence.
DISCUSSION/CONCLUSION
Study findings suggest that therapeutic alliance-based interventions are effective in improving medication adherence in Black patients with diabetes and hypertension. Further research to test the efficacy of therapeutic alliance-based interventions to improve medication adherence in Black patients should ideally incorporate cultural adaptation, theoretical framework, face-to-face delivery mode, and convenient locations.

Review
Efficacy and safety of treating patients with refractory schizophrenia with antipsychotic medication and adjunctive electroconvulsive therapy: a systematic review and meta-analysis.
BACKGROUND
The efficacy and safety of the combined treatment of refractory schizophrenia with antipsychotic medications and electroconvulsive therapy (ECT) remain uncertain.
AIMS
Conduct systematic review and meta-analysis of available literature in English and Chinese about ECT in the treatment of refractory schizophrenia.
METHODS
English and Chinese databases were searched for studies published prior to May 20, 2015 regarding the efficacy and safety of the combined treatment of refractory schizophrenia with antipsychotic medications and ECT. Two researchers selected and evaluated studies independently using pre-defined criteria. Review Manager 5.3 software was used for data analysis.
RESULTS
A total of 22 randomized control studies, 18 of which were conducted in mainland China, were included in the analysis. Meta-analysis of data from 18 of the 22 studies with a pooled sample of 1394 individuals found that compared to treatment with antipsychotic medications alone, combined treatment with antipsychotic medications and ECT had significantly higher rates of achieving study-specific criteria of 'clinical improvement' (RR=1.25, 95%CI=1.14-1.37). Based on the Grades of Recommendation, Assessment, Development, and Evaluation (GRADE) criteria, the quality of evidence for this assessment of efficacy was 'moderate'. However, the proportion of participants who experienced headache during the treatment was significantly higher in the combined treatment group (RR=9.10, 95%CI=3.97-20.86, based on a pooled sample of 517 from 8 studies) and the proportion who experienced memory impairment was also higher in the combined treatment group (RR=6.48, 95%CI=3.54-11.87, based on a pooled sample of 577 from 7 studies). The quality of evidence about these adverse events was rated as 'very low'.
CONCLUSIONS
There are very few high quality randomized controlled clinical trials about the combination of antipsychotic medications and ECT in the treatment of refractory schizophrenia. This meta-analysis found that the combination of antipsychotic medications and ECT could improve psychiatric symptoms in patients with refractory schizophrenia, but the incomplete methodological information provided for most of the studies, publication bias (favoring studies with better outcomes in the combined treatment group), and the low quality of evidence about adverse outcomes, cognitive impairment, and overall functioning raise questions about the validity of the results.

Meta-Analysis Review
The effectiveness of computerized order entry at reducing preventable adverse drug events and medication errors in hospital settings: a systematic review and meta-analysis.
BACKGROUND
The Health Information Technology for Economic and Clinical Health (HITECH) Act subsidizes implementation by hospitals of electronic health records with computerized provider order entry (CPOE), which may reduce patient injuries caused by medication errors (preventable adverse drug events, pADEs). Effects on pADEs have not been rigorously quantified, and effects on medication errors have been variable. The objectives of this analysis were to assess the effectiveness of CPOE at reducing pADEs in hospital-related settings, and examine reasons for heterogeneous effects on medication errors.
METHODS
Articles were identified using MEDLINE, Cochrane Library, Econlit, web-based databases, and bibliographies of previous systematic reviews (September 2013). Eligible studies compared CPOE with paper-order entry in acute care hospitals, and examined diverse pADEs or medication errors. Studies on children or with limited event-detection methods were excluded. Two investigators extracted data on events and factors potentially associated with effectiveness. We used random effects models to pool data.
RESULTS
Sixteen studies addressing medication errors met pooling criteria; six also addressed pADEs. Thirteen studies used pre-post designs. Compared with paper-order entry, CPOE was associated with half as many pADEs (pooled risk ratio (RR) = 0.47, 95% CI 0.31 to 0.71) and medication errors (RR = 0.46, 95% CI 0.35 to 0.60). Regarding reasons for heterogeneous effects on medication errors, five intervention factors and two contextual factors were sufficiently reported to support subgroup analyses or meta-regression. Differences between commercial versus homegrown systems, presence and sophistication of clinical decision support, hospital-wide versus limited implementation, and US versus non-US studies were not significant, nor was timing of publication. Higher baseline rates of medication errors predicted greater reductions (P < 0.001). Other context and implementation variables were seldom reported.
CONCLUSIONS
In hospital-related settings, implementing CPOE is associated with a greater than 50% decline in pADEs, although the studies used weak designs. Decreases in medication errors are similar and robust to variations in important aspects of intervention design and context. This suggests that CPOE implementation, as subsidized under the HITECH Act, may benefit public health. More detailed reporting of the context and process of implementation could shed light on factors associated with greater effectiveness.

Meta-Analysis Review
AIMS
The primary objective was to assess the occurrence rate of Medication-Related OsteoNecrosis of the Jaw (MRONJ) after dental extraction in patients treated with Antiresorptive Drugs (ARD) for OsteoPorosis (OP) or for oncological reasons. The secondary objective was to compare the extraction techniques regarding the occurrence of MRONJ.
MATERIALS AND METHODS
A systematic search in PubMed/MEDLINE, EMBASE and LILACS databases was performed. Prospective studies considering human patients treated with ARD and providing information regarding the occurrence of MRONJ after dental extraction were selected. Meta-analysis for incidence of MRONJ at the patient level was performed. The effect of administration route and surgical technique on MRONJ was evaluated.
RESULTS
The risk of MRONJ after dental extraction was significantly higher in patients treated with ARD for oncological reasons (3.2%) than in those treated with per os ARD for OP (0.15%) (p < 0.0001). Dental extraction performed with adjusted extraction protocols decreased significantly MRONJ development. Potential risk indicators such as concomitant medications and pre-existing osteomyelitis were identified.
CONCLUSION
The risk of MRONJ after dental extraction in patients treated with ARD exists, especially in patients treated for oncologic reasons. This risk tends to decrease with adjusted extraction protocols.

Review
Stereotactic lesioning of the bilateral globus pallidus (GPi) was one of the first surgical treatments for medication-refractory dystonia but has largely been abandoned in clinical practice after the introduction of deep brain stimulation (DBS). However, some patients with dystonia are not eligible for DBS. Therefore, we reviewed the efficacy, safety, and sustainability of bilateral pallidotomy by conducting a systematic review of individual patient data (IPD). Guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses and IPD were followed. In May 2020, Medline, Embase, Web of Science, and Cochrane Library were searched for studies reporting on outcome of bilateral pallidotomy for dystonia. If available, IPD were collected. In this systematic review, 100 patients from 33 articles were evaluated. Adverse events were reported in 20 patients (20%), of which 8 were permanent (8%). Pre-and postoperative Burke-Fahn-Marsden Dystonia Rating Movement Scale scores were available for 53 patients. A clinically relevant improvement (>20%) of this score was found in 42 of 53 patients (79%). Twenty-five patients with status dystonicus (SD) were described. In all but 2 the SD resolved after bilateral pallidotomy. Seven patients experienced a relapse of SD. Median-reported follow-up was 12 months (n = 83; range: 2-180 months). Based on the current literature, bilateral pallidotomy is an effective and relatively safe procedure for certain types of dystonia, particularly in medication-refractory SD. Although due to publication bias the underreporting of negative outcomes is very likely, bilateral pallidotomy is a reasonable alternative to DBS in selected dystonia patients. © 2020 The Authors.

Review
INTRODUCTION
A standard guideline concerning pre-hospital pain management is still a matter of discussion. Therefore, the current umbrella review is determined to perform a comprehensive search in databases and Grey literature and collect and summarize the guidelines and protocols dealing with prehospital pain management.
METHODS
In the present study, all of the available guidelines and protocols concerning pre-hospital pain management were reviewed. Presented guidelines are from 2010 up to present, as the majority of guidelines are considered old and become renewed after 10 years. Finally, the development quality of each guideline was evaluated using AGREE II instrument.
RESULTS
The search conducted in databases and non-indexed protocols resulted in inclusion of 12 pre-hospital pain management guidelines. The time interval of the guidelines was from 2010 to 2019. Four guidelines were designed for pain management in trauma patients and other guidelines were presented for all of the clinical conditions associated with pain. All of the 12 included guidelines presented pain management instructions in adults. Pain management in children was reported in 10 guidelines. All of the guidelines persisted on a standard method for pain evaluation. Pain management was categorized in three groups; mild, moderate and severe pain. Most of the guidelines recommend paracetamol as an optional treatment for management of mild pain in both adults and children. In management of moderate and severe pain, fentanyl and morphine were suggested for both adults and children. In most of the treatment guidelines fentanyl is the optional choice for children.
CONCLUSION
The present umbrella review has summarized the current evidence in pre-hospital pain management for the first time via investigation of guidelines and protocols related to the matter. Based on the obtained evidence, no guideline is yet presented concerning opioid-free management of moderate and severe pain. The evidence is insufficient for using non opioid medications such as ketamine.

Review
BACKGROUND
Among young people up to 18 years of age, approximately 5% have attention deficit hyperactivity disorder (ADHD), many of whom have symptoms persisting into adulthood. ADHD is associated with increased risk of co-morbid psychiatric disorders, including substance misuse. Many will be prescribed medication, namely methylphenidate, atomoxetine, dexamphetamine and lisdexamfetamine. If so, it is important to know if interactions exist and if they are potentially toxic.
METHODS
Three databases (Medline, EMBASE and PsychINFO) from a 22 year period (1992 - June 2014) were searched systematically. Key search terms included alcohol, substance related disorders, methylphenidate, atomoxetine, dexamphetamine, lisdexamfetamine, and death, which identified 493 citations (344 after removal of duplicates). The eligibility of each study was assessed jointly by two investigators, leaving 20 relevant articles.
RESULTS
We identified only a minimal increase in side-effects when ADHD medication (therapeutic doses) was taken with alcohol. None of the reviewed studies showed severe sequelae among those who had overdosed on ADHD medication and other coingestants, including alcohol.
CONCLUSIONS
The numbers across all the papers studied remain too low to exclude uncommon effects. Also, studies of combined effects with novel psychoactive substances have not yet appeared in the literature. Nevertheless, no serious sequelae were identified from combining ADHD medication with alcohol/illicit substances from the pre-novel psychoactive substance era.

Meta-Analysis Review
BACKGROUND
Perampanel a third-generation antiseizure medication, belongs to a new promising class of drugs called AMPA receptor antagonists, approved to treat focal-onset seizures with or without focal to bilateral tonic clonic seizures and primary generalized tonic-clonic seizures.
METHODS
This review included RCTs on patients with epilepsy exposed to perampanel compared with placebo, or one or more pre-existing antiseizure medications. Four databases and two clinical trial registries were searched from inception to July 2021. Included outcomes were 50% responder rate, seizure-free rate, discontinuation due to treatment-emergent adverse events (TEAE)s, having any TEAEs, and most reported TEAEs. Cochrane risk of bias tool was used to assess the internal validity of the included RCTs.
RESULTS
From 2211 retrieved citations, eight RCTs were included in the meta-analysis. Fifty-percent responder and seizure freedom rates were significantly higher in patients receiving perampanel when compared to placebo (RR 1.57, 95 % CI 1.35 to 1.82, I 15% and RR 2.79, 95% CI 1.58 to 4.93, I 7%, respectively). The 50% responder rates for 8mg and 12 mg, when compared to placebo, were similar. The most-reported TEAEs were dizziness and somnolence with <1% reporting serious psychological outcomes.
CONCLUSION
This systematic review reports significant reduction in seizures and a potential dose-based increase in discontinuations due to TEAE. The most-reported TEAEs were non-threatening, with the possibility of rare but serious adverse psychological outcomes. Further independent RCTs studying the most efficient dose for efficacy and safety are needed.
