Abstract
OBJECTIVE Breastmilk is recommended as the exclusive source of nutrition for infants younger than 6 months due to the numerous health benefits for both infants and mothers. Although many women are prescribed medications during pregnancy and postpartum, limited data are available to assist women in weighing the benefits compared to the risks of peripartum medication use. The goals of this paper are to discuss the importance of breastmilk for the health of both the mother and infant, evaluate the impact of medication use on women's infant feeding choice, describe the transfer of drugs to breastmilk and infants, and provide a framework for clinicians to support evidence-based counseling for women treated for mood disorders. RECOMMENDATIONS We recommend early pregnancy counseling to discuss the benefits and risks of medications during breastfeeding. The Surgeon General's Call to Action (2011) highlights the short and long-term negative health effects of not providing breastmilk. Integrating recommendations from the pediatric and obstetric teams allows patients to make decisions based on evidence and reach their infant feeding goals. Databases containing summaries of research findings and pharmacologic properties of the drug of interest are an essential resource for clinicians.

Cognitive Impairment in Patients with Bipolar Disorder: Impact of Pharmacological Treatment.
Xu, N, Huggon, B, Saunders, KEA
CNS drugs. 2020;(1):29-46
Abstract
Bipolar disorder is an illness characterised by periods of elated and depressed mood. These mood episodes are associated with changes in cognitive function and there is evidence to suggest that cognitive dysfunction persists during euthymia. The extent to which this is a function of the illness or a result of treatment is less clear. In this narrative review, we explore the impact of commonly used medications for bipolar disorder on cognitive function. Specific impairments in executive function and verbal memory have been noted in bipolar disorder. The impact of pharmacological treatments upon cognitive function is mixed with a number of studies reporting conflicting results. Interpretation of the data is further complicated by the variety of cognitive tests employed, study design, the relatively small numbers of patients included and confounding by indication. Overall, there is some evidence that while lithium improves some cognitive domains, it impedes others. Antipsychotics may be deleterious to cognition, although this may relate to the patient population in which they are prescribed. Sodium valproate is also associated with worse cognitive outcomes, while the impact of other antiepileptics is unclear. Overall the quality of evidence is poor and is derived from a relatively small number of studies that often do not account for the significant heterogeneity of the disorder or common comorbidities. The use of consistent methodologies and measures of cognition across studies, as well as in naturalistic settings, would enable more certain conclusions to be drawn.

Abstract
BACKGROUND Bipolar disorder is one of the most common serious mental illnesses, affecting approximately 60 million people worldwide. Characterised by extreme alterations in mood, cognition, and behaviour, bipolar disorder can have a significant negative impact on the functioning and quality of life of the affected individual. Compared with the general population, the prevalence of comorbid obesity is significantly higher in bipolar disorder. Approximately 68% of treatment seeking bipolar patients are overweight or obese. Clinicians are aware that obesity has the potential to contribute to other physical health conditions in people with bipolar disorder, including diabetes, hypertension, metabolic syndrome, cardiovascular disease, and coronary heart disease. Cardiovascular disease is the leading cause of premature death in bipolar disorder, happening a decade or more earlier than in the general population. Contributing factors include illness-related factors (mood-related factors, i.e. mania or depression), treatment-related factors (weight implications and other side effects of medications), and lifestyle factors (physical inactivity, poor diet, smoking, substance abuse). Approaches to the management of obesity in individuals with bipolar disorder are diverse and include non-pharmacological interventions (i.e. dietary, exercise, behavioural, or multi-component), pharmacological interventions (i.e. weight loss drugs or medication switching), and bariatric surgery. OBJECTIVES To assess the effectiveness of interventions for the management of obesity in people with bipolar disorder. SEARCH METHODS We searched the Cochrane Common Mental Disorders Controlled Trials Register (CCMDCTR) and the Cochrane Central Register for Controlled Trials (CENTRAL) to February 2019. We ran additional searches via Ovid databases including MEDLINE, Embase, and PsycInfo to May 2020. We searched the World Health Organization (WHO) trials portal (International Clinical Trials Registry Platform (ICTRP)) and ClinicalTrials.gov. We also checked the reference lists of all papers brought to full-text stage and all relevant systematic reviews. SELECTION CRITERIA Randomised controlled trials (RCTs), randomised at the level of the individual or cluster, and cross-over designs of interventions for management of obesity, in which at least 80% of study participants had a clinical diagnosis of bipolar disorder and comorbid obesity (body mass index (BMI) ≥ 30 kg/m²), were eligible for inclusion. No exclusions were based on type of bipolar disorder, stage of illness, age, or gender. We included non-pharmacological interventions comprising dietary, exercise, behavioural, and multi-component interventions; pharmacological interventions consisting of weight loss medications and medication switching interventions; and surgical interventions such as gastric bypass, gastric bands, biliopancreatic diversion, and vertical banded gastroplasty. Comparators included the following approaches: dietary intervention versus inactive comparator; exercise intervention versus inactive comparator; behavioural intervention versus inactive comparator; multi-component lifestyle intervention versus inactive comparator; medication switching intervention versus inactive comparator; weight loss medication intervention versus inactive comparator; and surgical intervention versus inactive comparator. Primary outcomes of interest were changes in body mass, patient-reported adverse events, and quality of life. DATA COLLECTION AND ANALYSIS Four review authors were involved in the process of selecting studies. Two review authors independently screened the titles and abstracts of studies identified in the search. Studies brought to the full-text stage were then screened by another two review authors working independently. However, none of the full-text studies met the inclusion criteria. Had we included studies, we would have assessed their methodological quality by using the criteria recommended in the Cochrane Handbook for Systematic Reviews of Interventions. We intended to combine dichotomous data using risk ratios (RRs), and continuous data using mean differences (MDs). For each outcome, we intended to calculate overall effect size with 95% confidence intervals (CIs). MAIN RESULTS None of the studies that were screened met the inclusion criteria. AUTHORS' CONCLUSIONS None of the studies that were assessed met the inclusion criteria of this review. Therefore we were unable to determine the effectiveness of interventions for the management of obesity in individuals with bipolar disorder. Given the extent and impact of the problem and the absence of evidence, this review highlights the need for research in this area. We suggest the need for RCTs that will focus only on populations with bipolar disorder and comorbid obesity. We identified several ongoing studies that may be included in the update of this review.

Abstract
INTRODUCTION Symptomatic and etiopathologic heterogeneity of schizophrenia (SCH) and bipolar disorder (BD) can be adequately addressed using a dimensional approach to psychopathology, as well as interpreting physiological properties and markers as predictors of disease onset and relapse. Risk factors, genetic and environmental, are likely to modify the neurobiological processes characteristic of certain physiological processes that manifest to a greater degree of overlapping symptoms. One of the most common laboratory tests in psychiatric patients is a standard laboratory blood test. It gives us an insight into the general somatic condition of the patient. It assesses the ability to transport oxygen to tissues and carbon dioxide back to the lungs via erythrocytes (RBC) and hemoglobin (HGB) as their most important constituents, and is also an indicator of iron status and blood oxygenation. AIM: Schizophrenia (SCH) and bipolar disorder (BD) are psychiatric disorders whose complex etiology and pathogenesis are still far from known. A correlation between red blood cell abnormalities and these diseases has been recognized in some studies. One of the most common laboratory tests in psychiatric patients is a standard laboratory blood test. However, so far there is a small number of published papers that relate to the relationship between laboratory parameters of blood and the aim of this paper is to reveal more light in this subject. METHODS The research was done as an observational prospective clinical study that has evaluated different physiological and pathological parameters in patients with BD and SCH over a two-year period. A total of 159 patients with schizophrenia, 61 patients diagnosed with bipolar disorder and 82 healthy subjects participated in this study. RESULTS At baseline, BD compared to SCH patients had higher mean lymphocyte count (2,6±0,7 vs. 2,0±0,6x109; p=0,006) and haemoglobin concentration (146,8±12,2 vs. 140,2±14,7 g/L; p=0,03), and significantly lower red cell distribution width (13,6±2,2 vs. 14,7±1,8%; p=0,008). In both BD and SCH patients there was a significant number of patients with low red blood cells count and low haemoglobin concentration, and high MCH and MCHC at baseline and at 3 and 6 months of follow up. CONCLUSIONS The finding that SCH as well as BD differed from controls with respect to red blood cells, hemoglobin, lymphocytes, and average platelet count was consistent with previous findings and could be understood as a qualitative measure in the evaluation of this sample. The fact that no association with other parameters was found, as well as an association with the diagnosis, does not exclude that these associations can be found in larger samples.

Abstract
Bipolar disorder (BD) is a severe mental disorder with a wide range of cognitive deficits, both in the euthymic and acute phase of the disease. Interestingly, in recent years, there has been a growing interest in investigating the impact of ω-3 polyunsaturated fatty acids on cognition in BD. In this context, the aim of this study is to evaluate the effect of docosahexaenoic acid (C22:6 ω-3, DHA) supplementation on cognitive performances in euthymic BD patients. This is an exploratory, single-centre, double-blind randomized controlled trial evaluating 12 weeks DHA supplementation (1250 mg daily) vs. a placebo (corn oil) in 31 euthymic BD patients compared to 15 healthy controls (HCs) on cognitive functions, assessed by the Brief Assessment of Cognition in Affective Disorder (BAC-A). Plasma levels of DHA were measured. After 12 weeks of treatment, no significant group differences were observed in all neuropsychological tests between the four groups, except for the emotion inhibition test, where HCs with DHA had higher scores compared to either BD with DHA (z = 3.9, p = 0.003) or BD with placebo (t = 3.7, p = 0.005). Although our results showed that DHA could be effective for ameliorating cognition in healthy subjects, future studies are still needed to clarify the impact of DHA on cognition in BD.

Journal of clinical epidemiology. 2019;:20-27
Abstract
OBJECTIVES We examined systematic adverse events (AEs) in Part 1 (of 2) of a study describing the assessment and reporting of AEs in clinical trials. STUDY DESIGN AND SETTING We examined 52 public and nonpublic data sources about trials of quetiapine for bipolar depression using data from the Multiple Data Sources study. We extracted and compared information about systematic AEs (i.e., AEs assessed for all participants) in six prespecified domains: cardiovascular, cholesterol, endocrine, extrapyramidal symptoms, mania, and weight. RESULTS Eligible trials did not assess and report the same systematic AEs, and most results were not available in public sources. Overall, public sources reported 159 results, of which 92 of 159 (58%) included sufficient statistical information to calculate the treatment effect and its precision. Nonpublic sources reported 636 results; 630 of 636 (99%) reported sufficient statistical information. CONCLUSION Systematic AEs were defined and analyzed in many ways, which led to many numerical results. Most systematic AEs were not mentioned in public sources. To minimize bias, methods for defining and analyzing potential AEs should be prespecified in trial registers and protocols. All trial results should be publicly available so that stakeholders can compare benefits and AEs. Trials could report core sets of AEs to facilitate decision-making.

Abstract
BACKGROUND Individuals with bipolar disorder (BD) are more likely than the general population to develop risk factors associated with cardiovascular disease, one of the leading causes of morbidity and mortality in this clinical population. To address this disproportionate medical burden, we developed Nutrition Exercise and Wellness Treatment (NEW Tx), a lifestyle intervention for individuals with BD. METHODS In this study, participants were randomized to NEW Tx (n = 19) or a treatment as usual waitlist (n = 19). We examine the intervention's efficacy to improve the physical and psychological outcomes of individuals with BD. Assessors were blind to participant condition throughout study duration. RESULTS The NEW Tx group reported increased weekly exercise duration and overall functioning, and decreased depression and illness severity over the study duration. However, only improvements in functioning were significantly greater in the NEW Tx group than in the control group. There were no group differences in weight loss or mood symptoms over the study duration. LIMITATIONS Limitations to this study include lack of objective measurement of exercise and a small and relatively homogeneous sample. CONCLUSIONS These data suggest that a manualized lifestyle intervention for BD may not be ideal to improve lifestyle changes in this clinical population. Further research is needed to pilot personalized approaches to creating a healthy lifestyle in BD.

Hsieh, YC, Chou, LS, Lin, CH, Wu, HC, Li, DJ, Tseng, PT
BMC psychiatry. 2019;(1):305
Abstract
BACKGROUND Bipolar disorder (BD) is a major psychiatric illness, however its physiopathology is unclear. The role of folate in the physiopathology of BD is controversial. We conducted this systematic review and meta-analysis to investigate the effect of folate in BD patients. METHODS We performed a thorough literature study of the PubMed, Embase, ScienceDirect, ClinicalKey, Cochrane Library, ProQuest, Web of Science, and ClinicalTrials.gov databases until December 21st, 2018. Random effects meta-analysis was conducted. RESULTS Six articles involving 481 patients with BD and 760 controls were included. The meta-analysis results suggested that serum folate levels in the patients with BD were significantly lower than those in the controls (Hedges' g = - 0.211, 95% confidence interval = - 0.391 to - 0.031, p = 0.021). CONCLUSION The current meta-analysis show it might be association between lower serum folate levels and patient with BD. However, we could not distinguish the potentially confounding effects of mood states on the folate levels. Further prospective studies including subjects with different mood states and possible physiopathology are warranted to investigate the association between folate deficiency and the etiology of BD.

Non-pharmacological interventions for preventing weight gain in patients with first episode schizophrenia or bipolar disorder: A systematic review.
Nyboe, L, Lemcke, S, Møller, AV, Stubbs, B
Psychiatry research. 2019;:112556
Abstract
Weight gain is a side effect of antipsychotic medication and highly prevalent in people with schizophrenia or bipolar disorder, increasing their overall cardio-metabolic risk. We conducted a systematic review on non-pharmacological interventions for preventing/reducing weight gain or increase in waist-circumference in young, newly diagnosed patients with schizophrenia or bipolar disorder. We searched major electronic databases from inception to 04/2019 on RCTs, pre- and post-test studies, and non-randomized controlled clinical trials. From a potential of 2963 hits, eight studies met the inclusion criteria (n = 438, mean age of 18.8 (13-45) years). The interventions comprised supervised and individually adjusted aerobic exercise activities (5 studies), individual lifestyle counselling vs. control condition (2 RCTs), and dietetic counselling and practical training of cooking and shopping (1 study). Physical activity and practical dietetic interventions seem to be more efficient than lifestyle counselling. However, the results shall be taken with caution due to the non-randomized designs and other methodologically deficits in the majority of the included studies.

Ioachimescu, AG, Fleseriu, M, Hoffman, AR, Vaughan Iii, TB, Katznelson, L
European journal of endocrinology. 2019;(1):31-40
Abstract
Background Dopamine agonists (DAs) are the main treatment for patients with hyperprolactinemia and prolactinomas. Recently, an increasing number of reports emphasized DAs' psychological side effects, either de novo or as exacerbations of prior psychiatric disease. Methods Review of prospective and retrospective studies (PubMed 1976, September 2018) evaluating the psychological profile of DA-treated patients with hyperprolactinemia and prolactinomas. Case series and case reports of psychiatric complications were also reviewed. Results Most studies were cross-sectional and had a control group of healthy volunteers or patients with nonfunctioning pituitary adenomas. There were few prospective studies, with/without control group, that included small numbers of patients. Compared with controls, patients with hyperprolactinemia generally had worse quality of life, anxiety, depression and certain personality traits. Patients receiving DAs had higher impulsivity scores than normoprolactinemic controls. Impulse control disorders (ICDs) were reported in both genders, with hypersexuality mostly in men. Multiple ICDs were sometimes reported in the same patient, usually reversible after DA discontinuation. In case reports, DA therapy was temporally associated with severe depression, manic episodes or psychosis, which improved after discontinuation and administration of psychiatric medications. Gender type of DA, dose and duration of therapy did not correlate with occurrence of psychiatric pathology. Conclusion Patients with hyperprolactinemia receiving DAs may develop changes in mood and behavior regardless of prior psychiatric history. Increased awareness for ICDs, depression, mania and other types of psychosis is needed by all physicians who prescribe DAs. Larger prospective controlled clinical studies are needed to delineate prevalence, risk stratification and management.
