Review
Early intervention is essential for favorable long-term outcomes in schizophrenia. However, there is limited guidance in the scientific literature on how best to choose between dopamine D receptor (DR) partial agonists and DR antagonists in early stages of schizophrenia. The aim of this meta-analysis was to directly compare DR partial agonists with DR antagonists for efficacy and tolerability, using randomized controlled trials (RCTs) that involved participants diagnosed with first-episode psychosis, schizophrenia, or related psychotic disorders with a duration of illness ≤5 years. Fourteen RCTs, involving 2494 patients, were included in the meta-analysis. Aripiprazole was the only identified DR partial agonist, and was not significantly different from pooled DR antagonists for overall symptom reduction or all-cause discontinuation. However, aripiprazole was more favorable than pooled DR antagonists for depressive symptoms, prolactin levels, and triglyceride levels. Specifically, aripiprazole was more favorable than paliperidone for triglyceride levels and more favorable than risperidone and olanzapine, but less favorable than ziprasidone, for weight gain. In addition, aripiprazole was less favorable for akathisia compared with second-generation DR antagonists, in particular olanzapine and quetiapine, and less favorable for discontinuation due to inefficacy than risperidone. Lastly, aripiprazole was more favorable than haloperidol for various efficacy and tolerability outcomes. In conclusion, aripiprazole's efficacy did not differ substantially from DR antagonists in the early course of schizophrenia, whereas differential tolerability profiles were noted. More double-blind RCTs are required comparing the efficacy and tolerability of aripiprazole as well as other DR partial agonists with DR antagonists in early stages of schizophrenia.

Meta-Analysis
OBJECTIVE
Recent studies have revealed that myo-inositol could be more influential in patients with polycystic ovary syndrome (PCOS). This study was aimed to determine and compare the effects of myo-inositol and metformin on hormonal and metabolic profiles and fertility outcomes.
MATERIALS AND METHODS
A comprehensive search was carried out among the English-language databases, including PubMed, Scopus, Cochrane Library, Google Scholar, and Web of Science, and the articles published from April 2010 to February 2019 were tracked down. The fixed and random-effects meta-analysis was used to estimate the pooled effect size. The meta-analysis was performed in Stata Version 14.0.
RESULTS
Nine studies with 331 patients treated with metformin and 307 patients treated with myo-inositol groups were included in the analysis. The research groups did not diverge significantly in terms of the basic characteristics, such as age and Body Mass Index (BMI). In the myo-inositol group, the levels of Luteinizing Hormone (LH) [12.55% (95% I: 11.41-13.68%)], S. testosterone [44.38% (95% CI: 38.09-50.67%)] and prolactin [7.97% (95% CI: 6.58- 9.37%)] were significantly higher than those recorded, i.e., LH [7.97% (95% CI: 6.58- 9.37%)], S. testosterone [8.48% (95% CI: 3.14-13.83%)] and prolactin [7.14% (95% CI: 1.50-14.79%)] for the metformin group (p<0.001).
CONCLUSIONS
Due to the dearth of related research and the high heterogeneity of the Randomized Clinical Trials (RCTs) included in other studies, the present systematic review could not establish any differences between metformin and myo-inositol concerning the hormonal profile and the ovarian function. However, the findings indicated that myo-inositol could improve fertility outcomes by modulating hyperandrogenism. Randomized trials are required to understand the mechanistic actions of myo-inositol in comparison with those of metformin regarding oocyte and embryo quality, fertilization, pregnancy, and live birth rates.

The coronavirus disease 2019 (COVID-19) has spread worldwide. It is still a pandemic and poses major health problem across the globe. In our review, clinical characteristics and laboratory parameters of COVID-19 patients were compiled systematically, with special reference to pregnant women in order to understand the disease course. An extensive literature search on various scientific databases for relevant manuscripts was conducted, which yielded 7 manuscripts for final analysis. The most common symptoms were fever (85%), cough (70.63%), chest tightness (37.36%), expectoration (33.27%), fatigue (32%), dyspnea (31.95%), and shortness of breath (31.19%), while hemoptysis (1.0%) was the least common. The associated comorbidities were hypertension (21.6%) and diabetes (10.0%). In terms of hematological parameters, lower total leukocyte counts were observed in 65% of cases and biochemical parameters, patients demonstrated elevated levels of albumin (53.72%), lactate dehydrogenase (45.71%), and natriuretic peptide (34.84%); however, total bilirubin was elevated in only 8% of cases. In the acute inflammatory cytokine profile, C-reactive protein (59.0%), tumor necrosis factor (58.0%), erythrocyte sedimentation rate (57.0%), interleukin-2 (IL- 2, 54.0%), and IL-6 (52.0%) levels were increased, while prolactin levels (6.5%) were minimally elevated. The recovery rate was approximately 41%, and mortality was about 6.5%. The study also concluded that the clinical symptoms of COVID-19 were similar among pregnant and non-pregnant women. There was no evidence of vertical transmission of COVID-19 infection. This review critically analyzed COVID-19 as a public health hazard in order to help policy makers, health care givers, and primary physicians to promote early diagnosis and prevention.

Meta-Analysis
Hyperprolactinemia (hPRL) often poses a diagnostic dilemma due to the presence of macroprolactin. Understanding the prevalence of macroprolactinemia (mPRL) has an important implication in managing patients with hPRL. The primary aim of this study was to determine the prevalence of mPRL globally and to explore selected factors influencing the prevalence estimate. Studies with original data related to the prevalence of mPRL among patients with hPRL from inception to March 2020 were identified, and a random effects meta-analysis was performed. Of the 3770 records identified, 67 eligible studies from 27 countries were included. The overall global prevalence estimate was 18.9% (95% CI: 15.8%, 22.1%) with a substantial statistical heterogeneity (I = 95.7%). The highest random effects pooled prevalence was observed in the African region (30.3%), followed by Region of the Americas (29.1%), European (17.5%), Eastern Mediterranean (13.9%), South-East Asian (12.7%), and Western Pacific Region (12.6%). Lower prevalence was observed in studies involving both sexes as compared to studies involving only female participants (17.1% vs. 25.4%) and in more recent studies (16.4%, 20.4%, and 26.5% in studies conducted after 2009, between 2000 and 2009, and before 2000, respectively). The prevalence estimate does not vary according to the age group of study participants, sample size, and types of polyethylene glycol (PEG) used for detection of macroprolactin (PEG 6000 or PEG 8000). With macroprolactin causing nearly one-fifth of hPRL cases, screening for mPRL should be made a routine before an investigation of other causes of hPRL.

Meta-Analysis
OBJECTIVES
We conducted a systematic review and meta-analysis of studies that compared levels of molecular biomarkers in women with peripartum cardiomyopathy (PPCM) to those in healthy pregnant and postpartum women to: (1) assess the evidence for prolactin (PRL) metabolism in PPCM, (2) ascertain the evidence for biomarkers of iron deficiency in PPCM, (3) identify other biomarkers associated with PPCM.
METHODS
We searched Medline, Embase, Cumulated Index to Nursing and Allied Health Literature (CINAHL) and the Global Health Library from inception without language restriction for studies that compared biomarkers levels in PPCM cases to healthy controls. Pooled standardised mean difference (SMD) was generated using a random effects model for the difference in levels of biomarkers.
RESULTS
Two studies assessed the association of PRL with PPCM, and reported that PPCM cases have higher levels of total PRL. No studies investigated iron metabolism in PPCM. Other biomarkers associated with PPCM included serum levels of natriuretic peptides (SMD=3.77, 95% CI 0.71 to 6.82), albumin (SMD=-0.67, 95% CI -1.01 to -0.32), C-reactive protein (SMD=1.67, 95% CI 0.22 to 3.12), selenium (SMD=-0.73, 95% CI -1.58 to 0.12), cardiac troponins (SMD=1.06, 95% CI 0.33 to 1.80), creatinine (SMD=0.51, 95% CI 0.33 to 0.69), white bloodcells (SMD=0.44, 95 % CI 0.07 to 0.82), haemoglobin (SMD=-0.45, 95% CI -0.64 to-0.26).
CONCLUSIONS
More robust molecular studies are needed to explore the association between prolactin and PPCM in human subjects and to determine the extent to which iron deficiency (with or without anaemia) contributes to the risk of PPCM.

Meta-Analysis
OBJECTIVE
To summarize and critically evaluate the evidence pertaining to the effectiveness and safety of auriculotherapy for breastfeeding.
METHODS
We performed a systematic search of 10 databases from their inception dates to May 15, 2017. Randomized controlled trials evaluating the effectiveness and safety of auriculotherapy for breastfeeding were included. Risk of bias was assessed using the Cochrane risk of bias tool.
RESULTS
This review included 31 randomized controlled trials with 5389 participants. Owing to the obvious clinical or statistical heterogeneity, a Meta-analysis was not conducted. Twenty-nine studies compared auriculotherapy plus routine care with routine care alone. No consistent adjunctive effect of auriculotherapy was observed in increasing the volume of milk production (9 studies showed significant results in favor of auriculotherapy and 5 did not) and serum prolactin level (7 studies showed significant results in favor of auriculotherapy and 2 did not), and in facilitating the initiation of milk secretion (10 studies showed significant results in favor of auriculotherapy and 7 did not). Two studies compared auriculotherapy with no treatment. Auriculotherapy as a monotherapy showed significant effects in increasing serum prolactin level and facilitating the onset of milk secretion; however, it was limited and inconclusive because only two studies were included in this comparison. The subgroup analysis of women who underwent cesarean delivery showed inconsistent results with respect to all outcomes. No serious adverse events were reported with the use of auriculotherapy. The methodological quality of the included studies was generally poor.
CONCLUSION
Although some studies showed positive results, no definite conclusion about the effectiveness and safety of auriculotherapy for breastfeeding could be drawn, owing to the low methodological quality of the included studies and the heterogeneity among trials. Large-scale, well-designed studies are warranted on this topic.

Meta-Analysis
BACKGROUND
Prolactin (PRL), an inflammatory hormone with cytokine properties, has long been considered to play a crucial role in the pathogenesis of autoimmune diseases, including systemic sclerosis (SSc). However, the plasma/serum levels of PRL in SSc were inconsistent in published studies. The aim of this study was to evaluate the plasma/serum levels of PRL in patients with SSc accurately.
METHODS
Electronic databases, including PubMed, EMBASE, Cochrane Library, CNKI, VIP and WANFANG databases, were searched up to October 15, 2019. Pooled standard mean difference (SMD) with 95% confidence interval (CI) was calculated by fixed-effect or random-effects model analysis. All statistical analyses were conducted with STATA 12.0.
RESULTS
Fifty three articles were obtained after searching databases, and 9 studies with 293 SSc patients and 282 controls were finally included. The meta-analysis showed that the plasma/serum PRL level in SSC patients was significantly increased compared with the healthy controls, with the SMD of 1.00 and 95% CI (0.56, 1.43). Subgroup analysis showed that female patients had higher plasma/serum PRL levels. However, no significant change in plasma/serum PRL levels was observed in male patients (P = .318). In subgroup analysis by detection type, electrochemiluminescence immunoassay (ECLIA) group and enzyme-linked immunosorbent assay (ELISA) group showed higher PRL levels among SSc patients.
CONCLUSIONS
In summary, our meta-analysis showed a significantly higher plasma/serum PRL level in SSc patients than healthy controls, and it was associated with gender and detection method.

Review
BACKGROUND
Gender-affirming hormone therapy for transgender women includes estrogen and antiandrogens (cyproterone acetate, spironolactone, or gonadotropin-releasing hormone agonists). Both estrogen and antiandrogens are reported to increase prolactin levels. The objective is to systematically review the evidence of the effects of antiandrogens on prolactin levels, hyperprolactinemia, and prolactinomas among transgender women on estrogen therapy.
METHODS
We searched PubMed, Embase, and PsycInfo up to May 2020. We included studies with at least 3 months follow-up that evaluated the effects of antiandrogens among transgender women and reported on prolactin levels, hyperprolactinemia, or image-confirmed prolactinomas. Two reviewers independently screened studies for eligibility, serially abstracted data, and independently assessed risk of bias and graded strength of evidence.
FINDINGS
We included 17 studies (16 publications): 8 prospective cohorts, 8 retrospective cohorts, and 1 cross-sectional study, each with a moderate to serious risk of bias. Among transgender women on estrogen, prolactin levels increased by over 100% with cyproterone acetate and by up to 45% with spironolactone. However, we were unable to isolate the effects of antiandrogens from estrogen therapy. We were unable to draw conclusions about effects of antiandrogens on hyperprolactinemia and prolactinomas.
INTERPRETATION
Prolactin levels may be increased in transgender women who are taking both estrogens and an antiandrogen. Future research is needed to determine the effects of different antiandrogens on prolactin levels separately from estrogen therapy. Ideally, future studies would be prospective, provide either a comparison of two different antiandrogens or compare combination of estrogen and antiandrogen therapy to estrogen alone, and control for possible confounders.

Comparative Study Meta-Analysis
AIM
This systematic review and random-effect model, network meta-analysis of the phase 3 trials in Japan assessed the efficacy and safety profile of lurasidone compared with olanzapine and quetiapine extended-release (QUE-XR) for the treatment of bipolar depression.
METHODS
The study included double-blind, randomized, placebo-controlled, phase 3 trials in Japan that included patients with bipolar depression. Outcomes included response rate (primary), remission rate (secondary), improvement of Montgomery-Åsberg Depression Rating Scale (MADRS) total score, discontinuation rates, and incidence of individual adverse events.
RESULTS
Three studies were included (n = 1223). Lurasidone and olanzapine but not QUE-XR were superior to placebo in response rate [risk ratio (95% credible interval): lurasidone = 0.78 (0.66, 0.92); olanzapine = 0.84 (0.71, 0.99); QUE-XR = 0.87 (0.73, 1.03)]. Lurasidone, olanzapine and QUE-XR were superior to placebo in remission rate [lurasidone = 0.90 (0.83, 0.98); olanzapine = 0.87 (0.77, 0.99); QUE-XR = 0.84 (0.73, 0.98)] and the improvement of MADRS total score. There were not differences in discontinuation rates between each antipsychotic and placebo. Compared with placebo, lurasidone was higher incidence of akathisia, and increased body weight and blood prolactin level; olanzapine was higher incidence of somnolence and ≥7% weight gain, and increased body weight, blood total cholesterol level, blood LDL cholesterol level, and blood triglyceride levels; QUE-XR was higher incidence of extrapyramidal symptoms, akathisia, somnolence, dry mouth, constipation and ≥7% weight gain, and increased body weight, blood total cholesterol level, blood LDL cholesterol level, and blood triglyceride levels.
CONCLUSIONS
Our results suggested although the efficacy of three SGAs was similar, there were the differences in the safety profile among the SGAs.
