Abstract Background This random-effects model meta-analysis of double-blind, randomized placebo-controlled trials compared recurrence rates in bipolar disorder (BD) patients between antipsychotic/mood stabilizer discontinuation and maintenance groups. Methods We conducted systematic literature search of Embase, PubMed, and CENTRAL databases without language restriction from inception until 22 May 2020. Independent investigators assessed studies and extracted data. We calculated risk ratios (RRs) and numbers needed to benefit or harm (NNTB/NNTH). Primary outcome was the recurrence rate of any mood episode at 6 months. Secondary outcomes were recurrence rates of depressive episodes and manic/hypomanic/mixed episodes and all-cause discontinuation at 6 months. We also investigated these outcomes at 1, 3, 9, 12, 18, and 24 months. Results We identified 22 studies (n = 5462) receiving aripiprazole, asenapine, divalproex, long-acting injectable (LAI)-aripiprazole, LAI-risperidone, lamotrigine, lithium, olanzapine, paliperidone, or quetiapine. Mean study duration was 64.50 ± 69.35 weeks. The maintenance group demonstrated lower recurrence rates of any mood episode, depressive episodes, and manic/hypomanic/mixed episodes as well as reduced all-cause discontinuation at every observational point. The RRs (95% confidence interval, NNTB/NNTH) of recurrence rate at 6 months were 0.61 (0.54–0.70, 5) for any mood episode, 0.72 (0.60–0.87, 13) for depressive episodes, and 0.45 (0.36–0.57, 6) for manic/hypomanic/mixed episodes. The RR for all-cause discontinuation at 6 months was 0.71 (0.61–0.82, 6). Conclusions Maintaining drug treatment during clinically stable BD prevented recurrence for up to 24 months. Discontinuation of medications for ⩾1 month significantly increased recurrence risk. However, 47.3% of patients who discontinued drugs for 6 months did not experience recurrence.

Abstract Background Symptoms of anxiety co-occur in a variety of disorders including in depressive episodes of bipolar disorder and in patients with thyrotoxicosis. Treatment of refractory bipolar disorder with supraphysiologic doses of levothyroxine (L-T4) has been shown to improve the phenotypic expression of the disorder and is associated with an increase of circulating thyroid hormones. However, it might be associated with somatic and mental adverse effects. Here we report the investigation of the influence of treatment with supraphysiologic doses of L-T4 on symptoms of anxiety in patients with refractory bipolar depression. Methods Post-hoc analysis from a 6-week, multi-center, randomized, double-blind, placebo-controlled study of the effects of supraphysiologic L-T4 treatment on anxiety symptoms in bipolar depression. Anxiety symptoms were measured weekly with the Hamilton anxiety/somatization factor (HASF) score of the Hamilton Depression Rating Scale (HAMD) and the State- and Trait Anxiety Inventory (STAI). Results Treatment of both groups was associated with a significant reduction in anxiety symptoms (p < 0.001) with no statistical difference between groups (LT-4: from 5.9 (SD = 2.0) at baseline to 3.7 (SD = 2.4) at study end; placebo: from 6.1 (SD = 2.4) at baseline to 4.4 (SD = 2.8) at study end; p = 0.717). Severity of anxiety at baseline did not show a statistically significant correlation to the antidepressive effect of treatment with supraphysiologic doses of L-T4 (p = 0.811). Gender did not show an influence on the reduction of anxiety symptoms (females: from 5.6 (SD = 1.7) at baseline to 3.5 (SD = 2.4) at study end; males: from 6.1 (SD = 2.3) at baseline to 4.0 (SD = 2.4) at study end; p = 0.877). Conclusions This study failed to detect a difference in change of anxiety between bipolar depressed patients treated with supraphysiologic doses of L-T4 or placebo. Comorbid anxiety symptoms should not be considered a limitation for the administration of supraphysiologic doses of L-T4 refractory bipolar depressed patients.

AbstractThe presentations and clinical courses of patients with bipolar disorder differ greatly by gender. In addition, medical therapy must be tailored differently for men and women because of emerging safety concerns unique to the female reproductive system. In November 2005, these topics were explored by a panel of experts in psychiatry, neurology, and reproductive health at a closed roundtable meeting in Dallas, Texas. This clinical information monograph summarizes the highlights of that meeting.Compared to men with bipolar disorder, women have more pervasive depressive symptoms and experience more major depressive episodes. They are also at higher risk for obesity and certain other medical and psychiatric comorbidities. Mood changes across the menstrual cycle are common, although the severity, timing, and type of changes are variable. Bipolar disorder is frequently associated with menstrual abnormalities and ovarian dysfunction, including polycystic ovarian syndrome. Although some cases of menstrual disturbance precede the treatment of bipolar disorder, it is possible that valproate and/or antipsychotic treatment may play a contributory role in young women.Pregnancy does not protect against mood episodes in untreated women. Maintenance of euthymia during pregnancy is critical because relapse during this period strongly predicts a difficult postpartum course. Suspending therapy in the first months of pregnancy may be an option for some women with mild-to-moderate illness, or those with a long history of euthymia during pre-pregnancy treatment. However, a mood stabilizer should be reintroduced either in the later stages of pregnancy or in the immediate postpartum period. Preliminary data suggest that fetal exposure to some mood stabilizers may raise the risk of major congenital malformations and neurodevelopmental delays. For women planning to become pregnant, clinicians may consider switching to other drugs before conception. The value and drawbacks of breastfeeding during treatment must be considered in partnership with the patient, with close monitoring of nursing infants thereafter. The risks and benefits of medical treatment for women with bipolar disorder should be carefully reconsidered at each stage of their reproductive lives, with a flexible approach that is responsive to the changing needs of patients and their families.

Introduction Recent literature advocates outpatient emergency department (ED) management of intussusception citing low recurrence rates and postreduction events after uncomplicated ileocolic reduction. However, few studies include both inpatient and outpatient cohorts. We performed a systematic review and meta-analysis to compare recurrence rates and length of hospital stay between the groups. Materials and Methods Studies published in English up to January 2018 were searched from Medline, Embase, Google Scholar, and Cochrane databases, using a combination of the terms ‘intussusception,’ ‘reduction,’ and ‘management’. A meta-analysis of studies comparing outcomes after successful intussusception reduction in children between inpatients and ED patients was performed. Results No randomized controlled trials (RCT) were found. Nine observational studies (eight retrospective and one prospective) were included, comprising 546 inpatients and 776 ED cases. There was no statistical difference in overall recurrence rate between inpatients (8.8%) and ED (10.1%) (pooled odds ratio [OR] = 1.09; 95% confidence interval [CI] 0.74–1.62; P = 0.66; I 2 = 0). Five studies reported early recurrence (<48 hours) with no difference (pooled OR = 1.27; 95% CI 0.46–3.48; P = 0.65; I 2 = 0). Five studies reported postdischarge recurrence rate with no difference (pooled OR = 1.57; 95% CI 0.71–3.48; P = 0.27; I 2 = 34%). Five studies reported recurrence requiring surgery with no difference (pooled OR = 0.99; 95% CI 0.32–3.06; P = 0.99; I 2 = 0). Methods of reduction were air, barium, or other contrast enema. Conclusion Management of intussusception in the ED after uncomplicated reduction appears acceptable. However, evidence levels are low, and RCT should be performed to adequately evaluate the safety of outpatient management of pediatric intussusception.

Introduction It is unclear whether the proportions of remission and the recurrence rates differ between endoscopic transsphenoidal surgery (TS) and microscopic TS in Cushing’s disease (CD); thus, we conducted a systematic review and meta-analysis to evaluate studies of endoscopic TS and microscopic TS. Methods We conducted a comprehensive search of PubMed to identify relevant studies. Remission and recurrence were used as outcome measures following surgical treatment of CD. Results A total of 24 cohort studies involving 1670 adult patients were included in the comparison. Among these studies, 702 patients across 9 studies underwent endoscopic TS, and 968 patients across 15 studies underwent microscopic TS. Similar baseline characteristics were observed in both groups. There was no significant difference in remission between the two groups: 79.7% (95% CI: 73.1–85.0%) in the endoscopic group and 76.9% (95% CI: 71.3–81.6%) in the microscopic group (P = 0.485). It appears that patients who underwent endoscopic surgery experience recurrence less often than patients who underwent microscopic surgery, with recurrence proportions of 11.0% and 15.9%, respectively (P = 0.134). However, if follow-up time is taken into account, both groups had a recurrence rate of approximately 4% per person per year (95% CI: 3.1–5.4% and 3.6–5.1%, P = 0.651). Conclusions We found that remission proportion and recurrence rate were the same in patients who underwent endoscopic TS as in patients who underwent microscopic TS. The definition of diagnosis, remission and recurrence should always be considered in the studies assessing therapeutic efficacy in CD.

Background: Superior vena cava (SVC) syndrome is caused by the occlusion of the SVC and can result in significant morbidity and mortality. Recently, endovascular therapy (ET) has become the standard of care for majority of these patients. We performed a systematic review of available literature to assess the contemporary technical success rate, restenosis rate, and recurrence rate of SVC syndrome following endovascular intervention. Methods: We searched PubMed, Cochrane Library, and Embase databases from 1988 to 2019 for studies on Endovascular Therapy for SVC syndrome. After screening 709 records, 13 studies were included. Screening was conducted using Rayyan QCRI software for systemic reviews. Studies included full-length journal articles on SVC syndrome and ET among adults (18+ years). Case reports, or case series with <20 patients were excluded. Data analysis was performed using OpenMeta software. Proportions and 95% confidence intervals (CIs) were calculated using random effects models. Heterogeneity among studies was assessed using Q and I 2 statistics. We evaluated the end-points of the technical success, restenosis rate and recurrence rates in SVC syndrome patients after endovascular stenting Results: A meta-analysis of 13 studies included a total of 1024 patients. The results of our meta-analysis show a weighted technical success rate of 98.6% (95% CI 0.97 – 0.99) (Fig. 1A), restenosis rate of 11.8% (95 CI 0.08-0.14) (Fig 1B) and recurrence rate of 9.9% (95% CI 0.06-0.13) (Fig 1C). Our studies had a substantial heterogeneity (I 2 ) of 52-80%. Figures:Figure 1A Figure 1B Figure 1C Conclusions: Our systematic review revealed high technical success rate, low restenosis, and recurrence rates after endovascular therapy supporting the paradigm of endovascular therapy as first line treatment for patients with SVC syndrome.

BackgroundThis meta-analysis assessed the equipotency of carbamazepine and lithium prophylaxis in bipolar disorder.MethodWe selected only randomised, double-blind, controlled studies comparing carbamazepine with lithium from a manual and computerised search, and subjected them to a quality inventory. Their statistical results were weighted by their quality score and combined. Results. Four studies met our criteria, yielding, overall, P = 0.15. This result is not straightforward because the studies showed significant heterogeneity (P < 0.01).ConclusionDifferences in statistical power and sensitivity of outcome measure explain this heterogeneity and the conflicting results of the studies. Therefore, the prophylactic efficacy of carbamazepine remains questionable.
