Review
BACKGROUND
Gestational gigantomastia (GG) is an uncommon pregnancy condition, and the underlying cause of GG has yet to be determined. Medical management and surgery are two treatment options for GG, and breast reduction or mastectomy with delayed reconstruction is the only available surgical option. We have conducted this systematic review to summarize and critically analyze all the GG data in the literature.
METHODS
The preferred reporting items for systematic reviews and meta-analysis (PRISMA) guidelines were adhered to in reporting this article. A systematic search was conducted in February 2022 for published case reports and case series on GG using the PubMed, MEDLINE, and Cochrane databases. The following keywords were used: macromastia, gestational gigantomastia, and gestational.
RESULTS
A total of 639 articles were searched, and only 66 case reports published between 1962 and 2022 were included. The mean patient's age at presentation was 28.79 years old. The majority of the patients were in their first trimester (n = 23, 47%). The main complaint was rapid bilateral breast enlargement (n = 54, 80.59%). Bromocriptine was the most common medical management used (n = 19/35, 54.28%). Bilateral breast reduction was the most common surgery (n = 24/48, 50%). Most patients had uneventful recovery (n = 40/54, 74.07%).
CONCLUSION
Gigantomastia is a difficult condition, in terms of its management. We have found that surgery is the gold-standard among all the cases reported; while Bromocriptine was the most commonly administered medical therapy. This systematic review provides a guideline for plastic surgeons to better facilitate their care of these patients.

Meta-Analysis
BACKGROUND
STN-DBS is a cornerstone in the treatment of advanced Parkinson's disease (PD). The traditional approach is to use an awake operative technique with microelectrode recording (MER). However, more centers start using an asleep MRI-guided technique without MER.
OBJECTIVE
We systematically reviewed the literature to compare STN-DBS surgery with and without MER for differences in clinical outcome.
METHODS
We systematically searched PubMed, Embase, MEDLINE, and Web of Science databases for randomized clinical trials and consecutive cohort studies published between 01-01-2000 and 26-08-2021, that included at least 10 PD patients who had received bilateral STN-DBS.
RESULTS
2,129 articles were identified. After abstract screening and full-text review, 26 studies were included in the final analysis, comprising a total of 34 study groups (29 MER and 5 non-MER). The standardized mean difference (SMD) in change in motor symptoms between baseline (OFF medication) and 6-24 months follow-up (OFF medication and ON stimulation) was 1.64 for the MER group and 1.87 for non-MER group (p = 0.59). SMD in change in levodopa equivalent daily dose (LEDD) was 1.14 for the MER group and 0.65 for non-MER group (p < 0.01). Insufficient data were available for comparative analysis of PDQ-39 and complications.
CONCLUSION
The change in motor symptoms from baseline to follow-up did not differ between studies that used MER and those that did not. The postoperative reduction in LEDD from baseline to follow-up was greater in the MER-group. In the absence of high-quality studies comparing both methods, there is a clear need for a well-designed comparative trial.

Meta-Analysis Review
High-dose versus low-dose inhaled levodopa (CVT-301) in patients with Parkinson disease for the treatment of OFF episodes: a meta-analysis of randomized controlled trials.
BACKGROUND
Levodopa is the most commonly used first-line drug for Parkinson's disease. However, during the period of medication, the generation of motor fluctuations affects the life quality of patients. CVT-301, as an inhaled levodopa for the treatment of OFF episodes, rose in response to this condition.
METHODS
We systematically searched Medline, EMBASE, Cochrane Library, and Clinicaltrials.gov for relevant randomized controlled trials, from the earliest available date to February 12, 2022, to evaluate the efficacy of high and low dose of inhaled levodopa in patients with Parkinson's disease.
RESULTS
A total of six multicenter, randomized controlled trials with 1166 patients were included. Compared with placebo, CVT-301 has a statistically significant effect on the treatment of Parkinson's patients with OFF episodes of medication interval. The UPDRS Part III score decreased more significantly in the high-dose group 30 minutes after administration than the low-dose group (WMD = - 4.51; 95% CI, - 7.34 to - 1.68; p = 0.002). More patients in the high-dose group achieved and maintained an on state up to 60 min after receiving study medication (RR = 1.17; 95% CI, 1.08 to 1.27; p < 0.001). And more patients were proved with improved PGIC scores in the high-dose group (RR = 1.13; 95% CI, 1.05 to 1.21; p = 0.001).
CONCLUSIONS
High doses CVT-301 can improve the motor function of the patient to some extent. There seems no risk of increasing adverse reactions.

Pituitary Dec 2022To make a systematic review and meta-analysis of studies evaluating the effect of cabergoline (CBG) in the treatment of non-functioning pituitary adenomas (NFPAs). (Meta-Analysis)
Meta-Analysis
PURPOSE
To make a systematic review and meta-analysis of studies evaluating the effect of cabergoline (CBG) in the treatment of non-functioning pituitary adenomas (NFPAs).
METHODS
The primary outcome was tumor shrinkage, using as cut-off a reduction of at least 20% of the NFPA size from baseline. The secondary outcomes were prevention of tumor progression, clinically required additional interventions and adverse events (AE). Search strategies were applied to MEDLINE, EMBASE, LILACS and CENTRAL. Independent reviewers assessed the study eligibility, extracted data, and evaluated risk of bias. Random meta-analysis for the proportion of tumor shrinkage, prevention of tumor progression, clinically required additional interventions and frequency of AE were conducted.
RESULTS
Five studies were included. The meta-analysis of proportion was 19% for tumor shrinkage (95% CI 8-38%, 4 studies, 108 participants), 50% for prevention of tumor progression (95% CI 35-64%, 5 studies, 187 participants), 14% for clinically required additional interventions (95% CI 6-30%, 4 studies, 128 participants) and 2% for adverse events (95% CI 1-6%, 3 studies, 157 participants).
CONCLUSIONS
Effect of CBG to promote tumor shrinkage in NFPAs was low, while prevention of tumor progression after surgery was seen in half of the cases, with a low frequency of adverse events.

Meta-Analysis
AIMS
Peripartum cardiomyopathy (PPCM) remains a major contributor to maternal morbidity and mortality worldwide. The disease is associated with various complications occurring mainly early during its course. Reported adverse outcomes include decompensated heart failure, thromboembolic complications, arrhythmias and death. We sought to systematically and comprehensively review published literature on the management and outcome of women with PPCM across different geographical regions and to identify possible predictors of adverse outcomes.
METHODS AND RESULTS
We performed a comprehensive search of relevant literature (2000 to June 2021) across a number of electronic databases. Cohort, case-control and cross-sectional studies, as well as control arms of randomized controlled trials reporting on 6- and/or 12-month outcomes of PPCM were considered eligible (PROSPERO registration: CRD42021255654). Forty-seven studies (4875 patients across 60 countries) met the inclusion criteria. Haemodynamic and echocardiographic parameters were similar across all continents. All-cause mortality was 8.0% (95% confidence interval [CI] 5.5-10.8, I = 79.1%) at 6 months and 9.8% (95% CI 6.2-14.0, I = 80.5%) at 12 months. All-cause mortality was highest in Africa and Asia/Pacific. Overall, 44.1% (95% CI 36.1-52.2, I = 91.7%) of patients recovered their left ventricular (LV) function within 6 months and 58.7% (95% CI 48.1-68.9, I = 75.8%) within 12 months. Europe and North America reported the highest prevalence of LV recovery. Frequent prescription of beta-blocker, angiotensin-converting enzyme inhibitor/angiotensin receptor blocker and bromocriptine/cabergoline were associated with significantly lower all-cause mortality and better LV recovery.
CONCLUSION
We identified significant global differences in 6- and 12-month outcomes in women with PPCM. Frequent prescription of guideline-directed heart failure therapy was associated with better LV recovery and lower all-cause mortality. Timely initiation and up-titration of heart failure therapy should therefore be strongly encouraged to improve outcome in PPCM.

Meta-Analysis Review
To assess the clinical efficacy and safety profile of opicapone (25 and 50 mg once daily) versus placebo. Levodopa-treated adults with Parkinson's disease. A systematic review and meta-analysis were conducted. Opicapone provided a greater reduction in the absolute OFF-time, increased the chances of ≥1-h reduction in the OFF-time and ≥1-h increase in the ON-time compared with placebo. Receiving opicapone more often facilitated levodopa dose reduction versus placebo. There were no differences in the occurrence of adverse events (severe and leading to drug discontinuation), but receiving opicapone increased the frequency of dyskinesia. Opicapone demonstrated superior clinical efficacy to placebo, with a comparable general safety profile.

Review
Down Syndrome (DS) is considered the most frequent form of Intellectual Disability, with important expressions of cognitive decline and early dementia. Studies on potential treatments for dementia in this population are still scarce. Thus, the current review aims to synthesize the different pharmacological approaches that already exist in the literature, which focus on improving the set of symptoms related to dementia in people with DS. A total of six studies were included, evaluating the application of supplemental antioxidant therapies, such as alpha-tocopherol; the use of acetylcholinesterase inhibitor drugs, such as donepezil; N-methyl-d-aspartate (NMDA) receptor antagonists, such as memantine; and the use of vitamin E and a fast-acting intranasal insulin. Two studies observed important positive changes related to some general functions in people with DS (referring to donepezil). In the majority of studies, the use of pharmacological therapies did not lead to improvement in the set of symptoms related to dementia, such as memory and general functionality, in the population with DS.

Meta-Analysis
INTRODUCTION
Long-term levodopa therapy for Parkinson's disease (PD) can cause levodopa induced dyskinesia (LID). Genetic predisposition has a significant role to play in inter-individual heterogeneity in the clinical manifestation of LID. Despite accumulating evidence for the role of COMT gene polymorphism (rs4680) as a genetic basis for LID, to date results have been inconsistent. Early assessment of the Catechol-O-Methyltransferase (COMT) genotype might be helpful to stratify PD patients concerning their individual risk for LID.
METHOD
In this meta-analysis, we have used 9 studies, which were selected through online databases. Statistical analysis was performed using R (v-3.6) software. 5 genetic models have been used in the present study: Allele model (A vs. G), Dominant model (AA+AG vs. GG), Homozygote model (AA vs. GG), Co-dominant/heterozygote model (AG vs. GG), and Recessive model (AA vs. AG + GG).
RESULTS
The results indicated a significant association between COMT rs4680 (Val158Met) polymorphism and LID risk. The genotype AA of COMT rs4680 is a risk factor for LID in PD patients under the recessive model (AA vs GG+AG) in the random-effect model. Analysis based on ethnicity showed that COMT rs4680 SNP allele A is a risk factor for LID development in Asian PD patients, while GG genotype is a risk factor for LID development in non-Asian PD patients using different genetic models.
CONCLUSION
The results of the present meta-analysis support that the COMT Val158Met polymorphism is a risk factor for the development of LID in PD patients having ethnic variations.

Meta-Analysis
OBJECTIVE
To examine the comparative efficacy and safety of cognitive enhancers by patient characteristics for managing Alzheimer's dementia (AD).
DESIGN
Systematic review and individual patient data (IPD) network meta-analysis (NMA) based on our previously published systematic review and aggregate data NMA.
DATA SOURCES
MEDLINE, Embase, Cochrane Methodology Register, CINAHL, AgeLine and Cochrane Central Register of Controlled Trials up to March 2016.
PARTICIPANTS
80 randomised controlled trials (RCTs) including 21 138 adults with AD, and 12 RCTs with IPD including 6906 patients.
INTERVENTIONS
Cognitive enhancers (donepezil, rivastigmine, galantamine and memantine) alone or in any combination against other cognitive enhancers or placebo.
DATA EXTRACTION AND SYNTHESIS
We requested IPD from authors, sponsors and data sharing platforms. When IPD were not available, we used aggregate data. We appraised study quality with the Cochrane risk-of-bias. We conducted a two-stage random-effects IPD-NMA, and assessed their findings using CINeMA (Confidence in Network Meta-Analysis).
PRIMARY AND SECONDARY OUTCOMES
We included trials assessing cognition with the Mini-Mental State Examination (MMSE), and adverse events.
RESULTS
Our IPD-NMA compared nine treatments (including placebo). Donepezil (mean difference (MD)=1.41, 95% CI: 0.51 to 2.32) and donepezil +memantine (MD=2.57, 95% CI: 0.07 to 5.07) improved MMSE score (56 RCTs, 11 619 participants; CINeMA score: moderate) compared with placebo. According to P-score, oral rivastigmine (OR=1.26, 95% CI: 0.82 to 1.94, P-score=16%) and donepezil (OR=1.08, 95% CI: 0.87 to 1.35, P-score=30%) had the least favourable safety profile, but none of the estimated treatment effects were sufficiently precise when compared with placebo (45 RCTs, 15 649 patients; CINeMA score: moderate to high). For moderate-to-severe impairment, donepezil, memantine and their combination performed best, but for mild-to-moderate impairment donepezil and transdermal rivastigmine ranked best. Adjusting for MMSE baseline differences, oral rivastigmine and galantamine improved MMSE score, whereas when adjusting for comorbidities only oral rivastigmine was effective.
CONCLUSIONS
The choice among the different cognitive enhancers may depend on patient's characteristics. The MDs of all cognitive enhancer regimens except for single-agent oral rivastigmine, galantamine and memantine, against placebo were clinically important for cognition (MD larger than 1.40 MMSE points), but results were quite imprecise. However, two-thirds of the published RCTs were associated with high risk of bias for incomplete outcome data, and IPD were only available for 15% of the included RCTs.

Meta-Analysis Review
The efficacy and tolerability of memantine for depressive symptoms in major mental diseases: A systematic review and updated meta-analysis of double-blind randomized controlled trials.
OBJECTIVE
To date, there is limited evidence on the antidepressant effects of memantine in patients with major mental diseases. We conducted a systematic review and meta-analysis to assess the efficacy of memantine in such populations.
METHODS
A literature search was performed for randomized controlled trials (RCTs) from the date of their inception until September 28, 2021, using PubMed, Medline, Embase, and the Cochrane Library. Changes in depression scores were the primary outcome. The response rate and remission rate to the treatment were secondary outcomes. We also assessed the dropout rate for tolerance.
RESULTS
Eleven double-blind RCTs were included with 899 participants. Memantine significantly reduced depressive symptom scores compared with the control group (k = 11, n = 899, Hedges' g = -0.17, 95% confidence interval [CI] = -0.30 to -0.04, p = 0.009) with a small effect size. For secondary outcomes, memantine did not show a significant effect on response rate nor remission rate. In the subgroup analysis, memantine significantly reduced depressive symptom scores in patients with mood disorders (k = 8, n = 673, Hedges' g = -0.17, 95% CI = -0.32 to -0.01, p = 0.035) with a small effect size, but not in patients with schizophrenia.
CONCLUSION
The present meta-analysis indicates that memantine effectively alleviates depressive symptoms in patients with mood disorders with a small effect size. Furthermore, memantine is well-tolerated and acceptable.
