Risks of Cardiac Valve Regurgitation and Heart Failure Associated with Ergot- and Non-Ergot-Derived Dopamine Agonist Use in Patients with Parkinson's Disease: A Systematic Review of Observational Studies.
BACKGROUND
Dopamine agonists (DAs) are commonly used in the therapy of Parkinson's disease (PD). However, several observational studies have suggested a putative association between DAs and specific cardiac adverse events.
OBJECTIVES
The aim of this study was to systematically review and summarize the available epidemiologic evidence on the association between use of ergot- and non-ergot-derived DAs and the risk of valvular heart disease, specifically cardiac valve regurgitation (CVR) and heart failure (HF) in patients with PD.
METHODS
The databases MEDLINE/PubMed and EMBASE were searched for all relevant articles published before February 2015. Studies were eligible if they met the following inclusion criteria: exposure to any approved non-ergot- or ergot-derived DA, presentation of original data, inclusion of an unexposed reference group, and valvular heart disease or heart failure as the primary outcome of interest.
RESULTS
Thirteen publications for CVR were identified (two nested case-control, one cohort and ten cross-sectional studies). Compared with non-ergot DAs or other anti-parkinsonian drugs, exposure to ergot-derived DAs pergolide and cabergoline was associated with an increased risk of CVR among PD patients. Incidence rate ratios (IRR) in the nested case-control and cohort studies ranged from 2.00 to 7.10 and 4.58 to 4.90, respectively. Longer treatment duration and higher dose of those DAs was also associated with a higher risk of CVR. Risk of HF was estimated in three nested case-control studies and one cohort study. Use of cabergoline (IRR range 1.30-2.39) and the non-ergot-derived DA pramipexole (IRR range 1.40-1.81) was associated with a higher HF risk among patients with PD. Pergolide may also be associated with a higher risk of HF.
CONCLUSION
Despite the heterogeneous methodological approaches of the included studies, there is strong evidence that treatment with pergolide and cabergoline is associated with a higher risk of CVR, and moderate evidence that treatment with pramipexole and cabergoline is associated with a higher risk of HF in patients with Parkinson's disease.

Meta-Analysis Review
CONTEXT
Dopamine agonists are the treatment of choice for prolactinomas and symptomatic idiopathic hyperprolactinemia. However, the optimal treatment strategy and treatment duration is not clear in all details.
OBJECTIVE
The aim of the study was to assess the effect of dopamine agonist withdrawal in patients with idiopathic hyperprolactinemia and prolactinomas.
DATA SOURCES
PubMed, the Cochrane Library, the Web of Science, and EMBASE were searched electronically. No restriction was made with respect to language.
STUDY SELECTION
Studies reporting the proportion of normoprolactinemic patients after withdrawal of dopamine agonist or studies in which this proportion could be calculated were eligible. Both observational studies and clinical trials were eligible. Nineteen studies were included in the meta-analysis, with a total of 743 patients.
DATA EXTRACTION
Data extraction was performed by two reviewers independently.
DATA SYNTHESIS
The pooled proportion of patients with persisting normoprolactinemia after dopamine agonist withdrawal was 21% in a random effects model [95% confidence interval (CI), 14-30%; I(2) 81%). Stratified analysis showed higher proportions of treatment success in idiopathic hyperprolactinemia (32%; 95% CI, 5-80%), compared with both microprolactinomas (21%; 95% CI, 10-37%), and macroprolactinomas (16%; 95% CI, 6-36%). In a random effects meta-regression adjusting for cause of hyperprolactinemia, a longer treatment duration was associated with treatment success (P = 0.015), whereas the use of cabergoline showed a trend of effect (P = 0.07).
CONCLUSIONS
This meta-analysis showed that hyperprolactinemia will recur after dopamine agonist withdrawal in a considerable proportion of patients. The probability of treatment success was highest when cabergoline was used for at least 2 yr.

Review
Positron emission tomography (PET) studies proposed a therapeutic window of D2 receptor occupancy (65%-80%) of antipsychotics for the treatment of schizophrenia in young adults. However, this conclusion has been drawn from clinical PET studies using small sample sizes (<20). Prospective PET studies that measured D2 occupancy levels and assessed extrapyramidal side effects (EPS) and/or treatment response induced by antipsychotics (excluding partial agonists) were identified, using MEDLINE and EMBASE (last search: March 2010). Individual subjects were divided into 2 groups based on EPS status (ie, presence or lack of newly emergent EPS) and treatment response (ie, a ≥ 25% or ≥ 50% reduction in the Positive and Negative Syndrome Scale or Brief Psychiatric Rating Scale). To evaluate the performance of this binary classification, sensitivity, specificity, and accuracy of consecutive cutoff points in the D2 occupancy were calculated: Accuracy = (True Positive + True Negative) / Total N. Twelve studies, including a total of 82 subjects, were included in our analyses. The cutoff points associated with 0.5 or greater in both sensitivity and specificity with the greatest accuracy were 77% to 78% for EPS, 60% for a 25% or greater symptom reduction, and 72% for a 50% or greater symptom reduction. These findings support the presence of a therapeutic window of 60% to 78% D2 occupancy of antipsychotics in young adults with schizophrenia and may suggest the presence of a continuum of effectiveness with increasing occupancy within this therapeutic window.

INTRODUCTION
Second-generation antipsychotics (SGAs) are frequently prescribed for the treatment of resistant anorexia nervosa. However, few clinical trials have been conducted so far and no pharmacological treatment has yet been approved by the Food and Drug Administration. The aim of this paper is to conduct a systematic scoping review exploring the effectiveness and safety of atypical antipsychotics in anorexia nervosa (AN).
METHOD
We conducted a systematic scoping review of the effectiveness and tolerability of SGAs in the management of AN. We included articles published from January 1, 2000, through September 12, 2022 from the PubMed and PsycInfo databases and a complementary manual search. We selected articles about adolescents and adults treated for AN by four SGAs (risperidone, quetiapine, aripiprazole or olanzapine). This work complies with the Preferred Reporting Items for Systematic Reviews and Meta-Analysis extension for scoping reviews (PRIMA-ScR) and was registered in the Open Science Framework (OSF) repository.
RESULTS
This review included 55 articles: 48 assessing the effectiveness of SGAs in AN and 7 focusing only on their tolerability and safety. Olanzapine is the treatment most frequently prescribed and studied with 7 randomized double-blind controlled trials. Other atypical antipsychotics have been evaluated much less often, such as aripiprazole (no randomized trials), quetiapine (two randomized controlled trials), and risperidone (one randomized controlled trial). These treatments are well tolerated with mild and transient adverse effects in this population at particular somatic risk.
DISCUSSION
Limitations prevent the studies both from reaching conclusive, reliable, robust, and reproducible results and from concluding whether or not SGAs are effective in anorexia nervosa. Nonetheless, they continue to be regularly prescribed in clinical practice. International guidelines suggest that olanzapine and aripiprazole can be interesting in severe or first-line resistant clinical situations.

The impact of pharmacological and non-pharmacological interventions on physical health outcomes in people with mood disorders across the lifespan: An umbrella review of the evidence from randomised controlled trials.
OBJECTIVE
People with mood disorders have increased risk of comorbid medical diseases versus the general population. It is paramount to identify interventions to improve physical health in this population.
METHODS
Umbrella review of meta-analyses of randomised controlled trials (RCTs) on pharmacological/non-pharmacological interventions for physical health outcomes/intolerability-related discontinuation in mood disorders (any age).
RESULTS
Ninety-seven meta-analyses were included. Among youths, against placebo, in depression, antidepressants/antipsychotics had higher discontinuation rates; in bipolar depression, olanzapine+fluoxetine worsened total cholesterol (TC)/triglycerides/weight gain (WG) (large ES). In adults with bipolar disorder, olanzapine worsened HbA1c/TC/WG (moderate/large ES); asenapine increased fasting glucose (small ES); quetiapine/cariprazine/risperidone induced WG (small/moderate ES). In bipolar depression, lurasidone was metabolically neutral. In depression, psychological interventions improved physical health-related quality of life (PHQoL) (small ES), fasting glucose/HbA1c (medium/large ES); SSRIs improved fasting glucose/HbA1c, readmission for coronary disease, pain (small ES); quetiapine/aripiprazole/olanzapine induced WG (small to large ES). Exercise improved cardiorespiratory fitness (moderate ES). In the elderly, fluoxetine yielded more detrimental cardiovascular effects than sertraline/escitalopram (large ES); antidepressants were neutral on exercise tolerance and PHQoL. In mixed age groups, in bipolar disorder aripiprazole was metabolically neutral; in depression, SSRIs lowered blood pressure versus placebo and serotonin-noradrenaline reuptake inhibitors (small ES); brexpiprazole augmentation caused WG and was less tolerated (small ES); exercise improved PHQoL (moderate ES).
CONCLUSIONS
Some interventions (psychological therapies, exercise and SSRIs) improve certain physical health outcomes in mood disorders, few are neutral, but various pharmacological interventions are associated with negative effects. Evidence from this umbrella review has limitations, should consider evidence from other disorders and should be integrated with recent evidence from individual RCTs, and observational evidence. Effective treatments with either beneficial or physically neutral profiles should be prioritized.

Review
BACKGROUND
Dopamine agonist-induced cerebrospinal fluid (CSF) rhinorrhea is an uncommon treatment-related complication arising in 6.1% of prolactinoma patients treated with dopamine agonists. Locally invasive prolactinomas may create CSF fistulae through formation of dural and osseous skull base defects. Tumor shrinkage secondary to dopamine agonist therapy unmasks skull base defects, thus inducing CSF rhinorrhea. In these cases, repair of the leak may be achieved through collaborative surgical intervention by rhinologists and neurosurgeons. Multiple variables have been investigated as potential contributors to the risk of CSF rhinorrhea development in medically treated prolactinoma patients, with little consensus.
OBJECTIVE
The primary aim of our study was the characterization of risk factors for CSF rhinorrhea development following dopamine agonist treatment.
METHODS
A systematic review of the literature was conducted to identify cases of CSF rhinorrhea following dopamine agonist treatment of prolactinoma. The clinical history, radiographic findings and treatment outcomes are discussed.
RESULTS
Fifty-four patients with dopamine agonist-induced CSF rhinorrhea were identified across 23 articles published from 1979 to 2019. Description of diagnostic imaging [computed tomography (CT)/magnetic resonance imaging (MRI)] was not provided for 18/54 subjects. For the 36 cases that described prolactinoma appearance on CT or MRI, invasion of the cavernous sinuses was reported in 13 (36.1%) and invasion of the sphenoid sinus was reported in 18 (50%).
CONCLUSION
Based on our systematic review, we propose that CT findings of osseous erosion of the sella or the anterior skull base may predict dopamine agonist-induced CSF rhinorrhea. We recommend obtaining a thin-slice CT of the sinuses in cases with MRI evidence of sphenoid involvement.

Meta-Analysis Review
BACKGROUND
Parkinson's disease (PD) can be a severely disabling condition in spite of therapies currently available. Systematic review and meta-analysis can provide an overview of a field of research and identify potential sources of bias and limits to efficacy. In this study we use these tools to describe the reported efficacy of dopamine agonists in animal models of PD.
METHODS
Publications were identified by electronic searching of three online databases. Data were extracted for neurobehavioural outcome, for study design and for the reporting of measures to avoid bias. Standardised mean difference meta-analysis was used to provide summary estimates of efficacy, with the effects of study quality and study design explored using stratified meta-analysis.
RESULTS
253 publications reported the use of a dopamine agonist in an animal model of PD; of these 121 reported data suitable for inclusion in meta-analysis. 47 interventions were tested in 601 experiments using 4181 animals. Overall, neurobehavioural outcome was improved by 1.08 standard deviations (SD; 95% Confidence Interval (CI) 0.97-1.19). Reporting of measures to reduce bias was low and publications which reported the blinded assessment of outcome had significantly smaller effect sizes (0.85, 95% CI 0.64 to 1.07) than those which did not (1.18, 95% CI 1.05 to 1.31, p < 0.005).
CONCLUSIONS
While dopamine agonists do appear to have efficacy in animal models of PD the low prevalence of reporting of measures to avoid bias is of concern. Systematic review of individual interventions may be helpful in the design of future preclinical and clinical trials.

Meta-Analysis Review
There is evidence of an association between cancer and certain types of altered eating behaviors, including orthorexia, food cravings, and food addiction. Given the growing interest in the topic throughout the scientific community we conducted a systematic review to summarize current evidence on the development of altered food behavior, including food addiction and cancer. The Cochrane Collaboration and the Meta-analysis Of Observational Studies in Epidemiology guidelines were followed to perform this systematic review. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement was used to report the process and results. The structured literature search was conducted on 19 April 2022, on PubMed/Medline and Scopus, combining free-text terms and medical subject headings. A total of seven articles were included once the selection process was completed. Food craving has been associated with different types of cancer in adults and young patients, as well as with orthorexia; conversely, compulsive eating has only been explored in patients with prolactinoma treated with dopamine agonists. This systematic review explored a new area of research that warrants further investigation. More research is required to better understand the relationship between cancer and food behavior.

Meta-Analysis Review
Heart failure (HF) is one of the leading causes of maternal mortality and morbidity in the United States. Peripartum cardiomyopathy (PPCM) constitutes up to 70% of all HF in pregnancy. Cardiac angiogenic imbalance caused by cleaved 16kDa prolactin has been hypothesized to contribute to the development of PPCM, fueling investigation of prolactin inhibitors for the management of PPCM. We conducted a systematic review and meta-analysis to assess the impact of prolactin inhibition on left ventricular (LV) function and mortality in patients with PPCM. We included English language articles from PubMed and EMBASE published upto March 2022. We pooled the mean difference (MD) for left ventricular ejection fraction (LVEF) at follow-up, odds ratio (OR) for LV recovery and risk ratio (RR) for all-cause mortality using random-effects meta-analysis. Among 548 studies screened, 10 studies (3 randomized control trials (RCTs), 2 retrospective and 5 prospective cohorts) were included in the systematic review. Patients in the Bromocriptine + standard guideline directed medical therapy (GDMT) group had higher LVEF% (pMD 12.56 (95% CI 5.84-19.28, I2=0%) from two cohorts and pMD 14.25 (95% CI 0.61-27.89, I2=88%) from two RCTs) at follow-up compared to standard GDMT alone group. Bromocriptine group also had higher odds of LV recovery (pOR 3.55 (95% CI 1.39-9.1, I2=62)). We did not find any difference in all-cause mortality between the groups. Our analysis demonstrates that the addition of Bromocriptine to standard GDMT was associated with a significant improvement in LVEF% and greater odds of LV recovery, without significant reduction in all-cause mortality.

Review
Aripiprazole is an atypical antipsychotic medication, and its use in treating borderline personality disorder (BPD) is debatable because it is not FDA-approved for treating BPD. This study aimed to investigate the efficacy and safety of aripiprazole in patients with BPD. On July 2, 2021, the protocol (CRD42021256647) was registered in PROSPERO. PubMed, Scopus, Web of Science, Ovid-Medline, Embase, PsycINFO, and Cochrane (CENTRAL) were searched without regard for language or publication date. We also searched trial registries on ClinicalTrials.gov and the WHO International Clinical Trials Registry Platform. Randomized clinical trials with adult patients diagnosed with BPD met the inclusion criteria. The Cochrane risk of bias for randomized trials (RoB-2) method was used to assess the quality of the included studies. We included two previously published randomized clinical trials. There were 76 patients with BPD, with 38, 12, and 26 assigned to the aripiprazole, olanzapine, and placebo groups, respectively. Most patients (88.16%) were females, with ages ranging from 22.1 to 28.14 yr. Aripiprazole has been proven to reduce anxiety, depression, anger, hostility, clinical severity, and obsessive-compulsive behavior, insecurity, melancholy, anxiety, aggressiveness/hostility, phobic anxiety, paranoid thinking, psychoticism, and somatization. The adverse effects were headache, insomnia, restlessness, tremor, and akathisia. The risk of bias was considerable in both trials, which is somewhat problematic considering that prejudice can lead to incorrect outcomes and conclusions. Aripiprazole has demonstrated encouraging outcomes in the treatment of patients with BPD. More randomized controlled studies are needed.
