Meta-Analysis
BACKGROUND
Increasing evidence suggests an association between third-generation antipsychotics (TGAs) and impulse control disorders (ICDs). This is thought to be due to their partial agonism of dopamine receptors. However, neither the relative nor absolute risks of ICDs in those prescribed TGAs are well established. To inform clinical practice, this systematic review and meta-analysis summarizes and quantifies the current evidence for an association.
METHODS
An electronic search of Medline, PsychINFO, EMBASE, and the Cochrane Clinical Trials Database was undertaken from database inception to November 2022. Three reviewers screened abstracts and reviewed full texts for inclusion. A random-effects meta-analysis was conducted with eligible studies.
RESULTS
A total of 392 abstracts were retrieved, 214 remained after duplicates were removed. Fifteen full texts were reviewed, of which 8 were included. All 8 studies found that TGAs were associated with increased probability of ICDs. Risk of bias was high or critical in 7 of 8 studies. Three studies were included in the pooled analysis for the primary outcome, 2 with data on each of aripiprazole, cariprazine, and brexpiprazole. Exposure to TGAs versus other antipsychotics was associated with an increase in ICDs (pooled odds ratio, 5.54; 2.24-13.68). Cariprazine and brexpiprazole were significantly associated with ICDs when analyzed individually. Aripiprazole trended toward increased risk, but very wide confidence intervals included no effect.
CONCLUSIONS
Third-generation antipsychotics were associated with increased risk of ICDs in all studies included and pooled analysis. However, the risk of bias is high, confidence intervals are wide, and the quality of evidence is very low for all TGAs examined.

Review
Diabetes mellitus (DM), one of the oldest diseases known to mankind has always been difficult to treat even with the availability of a variety of medications. In such a scenario, the Food and Drug Administration (FDA) has approved a novel therapeutic, bromocriptine, with a different mechanism of action than the traditional medications since 2009 but has not been used as either first-line therapy or add-on therapy. In this systematic review, we searched databases like PubMed, Medline, PubMed Central, Cochrane Library, Clinicaltrials.gov, and Wiley Online Library. The selected articles were screened using inclusion and exclusion criteria and quality appraised; finally, 11 studies including eight clinical trials and three narrative reviews were included. It was found that an increase in dopamine and serotonin levels were hypothesized to convert the insulin-resistant (IR) state to an insulin-sensitive (IS) state. Hence in DM, as there is an IR state, the administration of dopamine was hypothesized to increase insulin sensitivity. In our study based on included studies, it was found that bromocriptine was superior as an add-on therapy to metformin compared to metformin alone, also it was found beneficial in people failing treatment with any one oral hypoglycemic agent. On the contrary, bromocriptine was found inferior to teneligliptin in treating DM. Still, more studies are required to make an accurate and reliable assessment of the efficacy of bromocriptine in treating DM.

Review
BACKGROUND
Type 2 diabetes (T2DM) patients, including those in good glycemic control, have an increased risk of cardiovascular disease (CVD). Maintaining good glycemic control with drugs may reduce long-term CVD risk. Bromocriptine has been in clinical use for over 30 years, but the utility of bromocriptine in the treatment of diabetes patients has been proposed more recently.
OBJECTIVE
To summarize the available data regarding the effect of bromocriptine in T2DM management.
METHOD
A systematic literature search was conducted in the electronic databases, including Google Scholar, PubMed, Medline, and Science Direct, to locate studies that meet the objectives of this systematic review. Additional articles were included by conducting direct Google searches of the references cited by eligible articles located by the database search. The following search terms were used on PubMed "bromocriptine OR dopamine agonist AND diabetes mellitus OR hyperglycemia OR obese".
RESULT
Eight studies were included in the final analysis. 6210 of the 9391 study participants received bromocriptine treatment, while 3183 received a placebo. The studies demonstrated that patients who took bromocriptine treatment had significantly reduced blood glucose and BMI, which is the main cardiovascular risk factor in T2DM patients.
CONCLUSION
Based on this systematic review, bromocriptine may be used for T2DM treatment for its cardiovascular risk reduction effect, especially body weight reduction. However, advanced study designs might be warranted.

Meta-Analysis Review
Efficacy and Safety of Bromocriptine-QR as an Adjunctive Therapy on Glycemic Control in Subjects with Uncontrolled Type 2 Diabetes Mellitus: A Systematic Review and Meta-analysis.
INTRODUCTION
There has been an increasing awareness of the effects of combining bromocriptine-QR with other medications for diabetes mellitus type 2. This study aimed to assess the efficacy and safety of bromocriptine-QR as an adjunctive therapy for patients with uncontrolled type 2 diabetes mellitus.
METHODOLOGY
This systematic review is registered at the International Prospective Register of Systematic Reviews (CRD42022360326). Literature search was done via MEDLINE, NCBI, Google Scholar, Science Direct, Europe PMC and Cochrane Library databases. We included randomized controlled trials with participants 18 years old and above with uncontrolled type 2 diabetes mellitus. The primary outcome of interest is the efficacy and safety of bromocriptine-QR as an adjunctive therapy for glycemic control. Case reports, case series, reviews and animal studies were excluded. The risk of bias was reviewed using the Cochrane Risk of Bias tool. Meta-analysis was performed using Review Manager 5.4 and presented as a weighted mean difference and 95% confidence interval for changes from the baseline level.
RESULTS
Nine studies were included in the systematic review with a total of 2709 participants. The baseline HbA1c in the bromocriptine-QR group was 7.42% and 7.51% in the control group. The bromocriptine-QR group was favoured, outperforming the control group in terms of reducing hemoglobin A1c(HbA1c), with a statistically significant difference (weighted mean difference -0.6%; 95% CI [-0.83,-0.36]; p<0.00001). The most common side effects were nausea (33.75% vs 6.92%), fatigue (13.11% vs 5.94%), and headache (11.17% vs 6.87%).
CONCLUSION
Administration of bromocriptine-QR at a dose range of 1.6 to 4.8 mg/day as an adjunctive therapy reduced HbA1c and FBG in patients with uncontrolled type 2 diabetes mellitus (T2DM). However, there were also statistically greater odds of the occurrence of adverse events such as nausea, vomiting, and headache compared to controls.

IMPORTANCE
Prolactinomas occurring during the reproductive period exhibit a characteristic behavior. There are, however, gaps in the literature regarding the behavior of these tumors after menopause.
OBJECTIVE
This study aimed to review and characterize the influence of menopause on prolactinoma behavior.
EVIDENCE REVIEW
A systematic review of observational prospective or retrospective studies and clinical trials on prolactinomas was conducted in two situations: tumors diagnosed in the reproductive period (before menopause), with follow-up in the postmenopausal period, or prolactinomas diagnosed in the postmenopausal period, without language or date restrictions. Data extracted from the articles included patient and tumor characteristics (prolactinoma type, previous treatment, symptoms, and serum prolactin [PRL] levels).
FINDINGS
This study included five studies comprising 180 participants. Prolactinomas diagnosed in women of reproductive age are treated with dopaminergic agonists (DAs), with indications of treatment withdrawal after menopause, exhibited stable tumor behavior and PRL levels. Considering the diagnosis during the postmenopausal period, macroprolactinomas were more prevalent and showed tumor shrinkage when DAs were used. Cabergoline, the most commonly used drug, lowers PRL levels and reduces symptoms associated with adenoma.
CONCLUSIONS AND RELEVANCE
Microadenomas diagnosed before menopause can be followed up without treatment. Prolactinomas diagnosed after menopause are typically macroadenomas. Cabergoline remains the treatment of choice in the presence of clinical or compressive symptoms. We recommend at least one annual follow-up for such patients.

BACKGROUND
Prolactinomas are common tumours that significantly reduce quality-of-life (QOL) due to sellar mass effect, secondary hypogonadism, and the peripheral effects of prolactin. Understanding the factors that influence QOL would provide insights into therapeutic targets to optimise patient outcomes and improve wellbeing in prolactinoma.
METHODS
A systematic review was performed in accordance with the PRISMA statement. Studies that reported patient QoL using validated metrics were included. Bias and methodological rigour were assessed using the MINORS criteria.
RESULTS
A total of 18 studies were identified studies were available for review, comprising 877 patients. Most were small cross-sectional studies at high risk of bias. Prolactinoma exhibit worse QOL than healthy controls, particularly mental and psychosocial wellbeing. QOL is also worse than patients with non-functional adenomas, but better than those with Cushing's disease and acromegaly. QOL correlates with prolactin levels, and approaches population baseline with prolonged biochemical control. Dopamine agonists and surgery both improve overall QOL, however improvements are more rapid with surgery.
CONCLUSION
Poor quality of life in prolactinoma is multifactorial, related to biochemical control, side effects of therapy, and sellar mass effect. Targeting persistent symptoms, reducing healthcare costs, and reducing side-effects of therapy are avenues to improving QOL in patients with prolactinoma.

Meta-Analysis Review
Role of adjunctive cariprazine for treatment-resistant depression in patients with major depressive disorder: A systematic review and meta-analysis of randomized controlled trials.
INTRODUCTION
Cariprazine is an orally active dopamine D3-preferring D3/D2 receptor and serotonin 5-HT1A receptor partial agonist, being considered as a treatment for refractory MDD. Therefore, we aim to perform the first meta-analysis of current literature, to collate changes in depression from baseline and assess tolerability of adjunctive cariprazine in MDD populace.
METHODS
PubMed, Embase, Google Scholar, ClinicalTrials.Gov, and Cochrane Library were searched from inception till 1st September 2023. RCTs of adult patients with refractory MDD under adjunctive cariprazine vs. placebo were included. Primary outcomes included improvement in MADRS, CGI-S, and HAM-D 17 scores. Secondary outcomes included treatment-emergent adverse events. The statistical analysis was performed using generic inverse variance with random-effects model. The overall risk ratios (RR) were calculated for dichotomous outcomes.
RESULTS
A total of five RCTs were analysed, enrolling 2013 participants (cariprazine: 959 participants, Placebo: 1054). Supplementation of ADT with cariprazine demonstrated a significant improvement in MADRAS, CGI-S and HAMD-17 scores from baseline (LSMD: -1.88, 95% CI [-2.94, -0.83], p=0.0005), (LSMD: -0.18, 95% CI [-0.29, -0.07], p=0.002), and (LSMD: -0.96, 95% CI [-1.70, -0.21], p=0.01) respectively. Treatment with adjunctive cariprazine therapy demonstrated significantly increased incidence of akathisia, nausea, dizziness, fatigue, restlessness, somnolence, and tremors when compared with placebo.
CONCLUSION
Our meta-analysis provides evidence supporting the efficacy of adjunctive cariprazine in patients with refractory MDD. However, it is essential to consider the safety profile of cariprazine, particularly the increased risk of adverse events. The vigilant monitoring and management of these side effects should be integrated into clinical practice to minimize discontinuation rates and optimize patient outcomes.

Meta-Analysis
BACKGROUND
Dopamine agonists (DAs) constitute the standard therapeutic scheme for restless leg syndrome (RLS) because they have been proven to be effective. However, DAs may change sleep parameters, thus having adverse effects on patient condition. This meta-analysis clarified the effects of DAs used in RLS treatment on the sleep architecture.
METHODS
PubMed, Embase, and Cochrane Central databases were searched for randomized control trials (RCT) (up to October 2023) that discussed the effects of DAs on sleep architecture in patients with RLS. A meta-analysis employing a random-effects model was conducted. The patients were divided into subgroups according to individual DAs and treatment duration (1 day or ≥4 weeks).
RESULTS
Thirteen eligible randomized placebo-controlled trials were included in the assessment. The effects of three DAs (i.e., pramipexole, ropinirole, and rotigotine) on rapid eye movement (REM) sleep, slow-wave sleep (SWS), and sleep efficiency (SE) were analyzed. Overall, pramipexole significantly improved SE but decreased the percentage of REM sleep among treated patients. Ropinirole also enhanced SE compared with the placebo group. Rotigotine did not affect SE and REM sleep. Subgroup analysis found that pramipexole used for 1 day and ≥4 weeks significantly diminished the percentage of REM sleep. Ropinirole used for 1 day showed similar REM sleep patterns. Finally, none of the three DAs affected SWS.
CONCLUSIONS
This meta-analysis demonstrated that DAs significantly affect sleep parameters.

Comparative Study Review
This systematic review aims to evaluate the efficacy and safety of Pyridoxine compared to Dopaminergic agonists (cabergoline and bromocriptine) in post-partum lactation inhibition. Cochrane Central, PubMed/MEDLINE, Cochrane Central, ScienceDirect, ClinicalTrials.gov, Web of Science, CINAHL and Google Scholar, covering the period from inception to November 2023. Additionally, the bibliographies of included articles and previous meta-analyses were screened for any relevant articles. The systematic review was conducted according to the Cochrane Handbook for Systematic Reviews of Interventions. The outcomes of interest encompassed inhibition of lactation, breast pain/tenderness, breast engorgement, milk secretion, fever, mastitis, prolactin level and adverse events related to pyridoxine, cabergoline and bromocriptine. Methodological quality assessment was conducted using the Cochrane risk of bias assessment tool for rigorous evaluation. Three clinical trials assessed the effectiveness of pyridoxine and dopaminergic agents (cabergoline and bromocriptine) for lactation inhibition. It was assessed by using different assessment methods such as a scale for milk secretion, serum prolactin levels, and questionnaires for assessing breast engorgement, breast pain, and milk leakage. On the global assessment of the therapeutic efficacy of dopaminergic agents, it was found that there was significant inhibition of lactation as compared to pyridoxine (p < 0.001). In conclusion, this systematic review contributes significant insights into lactation inhibition interventions. Dopaminergic agonists, specifically cabergoline and bromocriptine, stand out as more effective and tolerable choices compared to Pyridoxine. These findings provide a foundation for informed clinical decisions and underscore the need for careful consideration of lactation inhibition strategies in diverse clinical contexts.

A comparison of recurrence rates after discontinuation of second-generation antipsychotic long-acting injectable versus corresponding oral antipsychotic in the maintenance treatment of bipolar disorder: A systematic review.
It has been previously reported that among patients with schizophrenia that long-acting injectable (LAI) antipsychotic formulations can delay time to relapse longer when compared to their oral equivalents when patients discontinue therapy. Unanswered is whether this same pattern would be observed for patients with bipolar disorder receiving maintenance treatment. A systematic review was undertaken to identify relevant studies of LAI antipsychotics in maintenance treatment of bipolar disorder, employing a placebo-controlled randomized withdrawal design, and where equivalent studies using the corresponding oral formulation were also available. We found five studies [one aripiprazole monohydrate once monthly (AOM) study, one oral aripiprazole (OARI) study, two 2 weeks risperidone-LAI (RIS-LAI) studies, and one oral paliperidone (OPAL) study]. Numerically lower recurrence rates at 2, 4, 6, 8, 12, 16, 20, and 26 weeks were observed when AOM was discontinued when compared with discontinuation from OARI. Numerically lower recurrence rates at 2, 4, 6, 8, and 16 weeks were observed when RIS-LAI was discontinued when compared with discontinuation from OPAL. These results can be interpreted as a substantial delay in time to recurrence with a LAI antipsychotics formulation compared to the oral equivalent when medication is discontinued in patients with mania who had been stabilized on LAI antipsychotics or corresponding oral antipsychotics.
