Depression in midlife women attending a menopause clinic is associated with a history of childhood maltreatment.

A growing body of literature has suggested that the perimenopause and the early postmenopausal years are associated with an increased risk of experiencing symptoms of depression and the development of first-onset and recurrent episodes of major depressive disorder. Multiple risk factors have been identified, including stressful life events and lower socioeconomic status, as well as early life adversity. The objective of the current study was to characterize the influence of early life childhood maltreatment and incident depression among women experiencing bothersome menopausal symptoms. Participants were recruited from two university-affiliated specialty clinics caring for women with bothersome menopausal symptoms. Assessments included the Childhood Trauma Questionnaire (CTQ), the Center for Epidemiological Studies - Depression (CES-D) scale and the Greene Climacteric Scale. Findings from this cross-sectional study indicate that adverse childhood experiences, as measured using the CTQ, were highly prevalent among women seeking care for bothersome menopausal symptoms (66%). Further, a greater score on the CTQ was significantly associated with higher CES-D scores, as well as with a greater burden of menopausal symptoms, after adjusting for confounding. Our findings lend support to the growing body of literature suggesting that early life stress affects mental health well into adulthood.

Objective and subjective vasomotor symptom outcomes in the CBT-Meno randomized controlled trial.

Objective: Vasomotor symptoms (hot flashes, night sweats) are common during the menopausal transition. Pharmacotherapy is effective but is associated with health risks for some women. There is an increasing demand for non-pharmacological interventions. The CBT-Meno protocol is a psychological intervention targeting a range of common menopausal symptoms. We compared the impact of CBT-Meno vs. waitlist on objective and subjective measures of vasomotor symptoms and on the relationship between vasomotor symptoms and sleep difficulties.Materials: The participants were 36 perimenopausal or postmenopausal women with co-occurring depressive symptoms who participated in the CBT-Meno trial (clinicaltrials.gov NCT02480192). Subjective measures included the Hot Flash Related Daily Interference Scale, the Greene Climacteric Scale, and the Pittsburgh Sleep Quality Inventory. Objective (physiological) and 'in-the-moment' measures of vasomotor symptoms were assessed with sternal skin conductance.Results: Greater improvements in vasomotor 'bothersomeness' and 'interference' were observed in the CBT-Meno condition compared to the waitlist condition. No between-group differences were observed in vasomotor frequency (subjectively or objectively recorded) or severity ratings. Sleep disturbance was unrelated to objectively measured vasomotor symptom frequency.Conclusion: The CBT-Meno trial improved subjective but not objective (physiological) measures of vasomotor symptoms. Self-reported sleep difficulties were unrelated to subjective or objective vasomotor symptoms.

The Menopause Visual Analogue Scale: a new tool for measuring the severity and response to treatment of symptoms throughout the menopausal transition.

OBJECTIVES: This study aimed to assess the reliability and validity of the Menopause Visual Analogue Scale (MVAS) in measuring symptoms throughout the menopausal transition. METHODS: Two independent samples of women undergoing the menopausal transition completed both the MVAS and the Greene Climacteric Scale (GCS) at a women's mental health clinic between 2008 and 2016. Data for the first sample were obtained using a retrospective chart review of patients seen between 2008 and 2012 (N1 = 75) and data for the second sample came from a prospective study conducted between 2013 and 2016 (N2 = 86). Internal consistency was assessed using Cronbach's α and Pearson's correlation coefficient was used to evaluate concurrent validity. Bland-Altman plots were developed to assess the degree of agreement between the scales. RESULTS: Internal consistency for the physical and psychological domains of the MVAS was 0.80-0.81 and 0.92-0.94, respectively. Pearson's correlations between the MVAS and the GCS were high for both physical (rphys = 0.74-0.76, p < 0.01) and psychological (rpsych = 0.70-0.72, p < 0.01) components in both samples. Changes in MVAS physical and psychological scores in response to treatment were correlated with changes in GCS physical and psychological scores (rphys = 0.69, p < 0.01; rpsych = 0.49, p < 0.01) in the second sample. Bland-Altman plots indicate low to moderate levels of agreement between most portions of the MVAS and the GCS. CONCLUSIONS: These findings suggest that the MVAS has potential for assessing both severity and change in symptoms throughout the menopausal transition, subject to exploring limitations identified in the analysis and application to other populations.

Association of intracortical myelin and cognitive function in bipolar I disorder.

OBJECTIVE: Although cognitive dysfunction persists through affective and euthymic states in bipolar disorder (BD), its neurobiological correlates remain undetermined. We explore whole-cortex intracortical myelin (ICM) and cognition in BD-I and controls. METHODS: T1 -weighted images (3T) optimized for ICM measurement were analyzed using a surface-based approach. MRI signal was sampled at cortical mid-depth. Cognitive performance was measured via standardized computerized battery and paper-and-pencil Trails B. RESULTS: ICM was associated with verbal memory (VM) in BD throughout a cortical network identified with pertinence to VM function, with strongest effects in left caudal middle temporal cortex and left dorsolateral prefrontal cortex (Pcorrected  < 0.05). Subanalyses revealed specific association with correct word recognition, without delay. Processing speed, executive function, and reaction time were also predicted by ICM in BD, but not controls, although this did not survive Bonferroni correction. CONCLUSION: This is the first study to show VM association with ICM in BD. ICM has been implicated in the integrity of neural connections and neural synchrony. VM dysfunction is one of the most replicated cognitive abnormalities in BD. Therefore, these results provide a novel mechanism for understanding cognitive dysfunction in BD, which can aid in the development of targeted therapeutics to improve cognitive outcomes in BD.

Increased illness burden in women with comorbid bipolar and premenstrual dysphoric disorder: data from 1 099 women from STEP-BD study.

BACKGROUND: The impact of comorbid premenstrual dysphoric disorder (PMDD) in women with bipolar disorder (BD) is largely unknown. AIMS: We compared illness characteristics and female-specific mental health problems between women with BD with and without PMDD. MATERIALS & METHODS: A total of 1 099 women with BD who participated in the Systematic Treatment Enhancement Program for Bipolar Disorder (STEP-BD) were studied. Psychiatric diagnoses and illness characteristics were assessed using the Mini International Neuropsychiatric Interview. Female-specific mental health was assessed using a self-report questionnaire developed for STEP-BD. PMDD diagnosis was based on DSM-5 criteria. RESULTS: Women with comorbid BD and PMDD had an earlier onset of bipolar illness (P < 0.001) and higher rates of rapid cycling (P = 0.039), and increased number of past-year hypo/manic (P = 0.003), and lifetime/past-year depressive episodes (P < 0.05). Comorbid PMDD was also associated with higher proportion of panic disorder, post-traumatic stress disorder, generalized anxiety disorder, bulimia nervosa, substance abuse, and adult attention deficit disorder (all P < 0.05). There was a closer gap between BD onset and age of menarche in women with comorbid PMDD (P = 0.003). Women with comorbid PMDD reported more severe mood symptoms during the perinatal period and while taking oral contraceptives (P < 0.001). DISCUSSION: The results from this study is consistent with research suggesting that sensitivity to endogenous hormones may impact the onset and the clinical course of BD. CONCLUSIONS: The comorbidity between PMDD and BD is associated with worse clinical outcomes and increased illness burden.

RNA-sequencing profiles hippocampal gene expression in a validated model of cancer-induced depression.

To investigate the pathophysiology of cancer-induced depression (CID), we have recently developed a validated CID mouse model. Given that the efficacy of antidepressants in cancer patients is controversial, it remains unclear whether CID is a biologically distinct form of depression. We used RNA-sequencing (RNA-seq) to investigate differentially expressed genes (DEGs) in hippocampi of animals from our CID model relative a positive control model of depressive-like behavior induced with chronic corticosterone (CORT). To validate RNA-seq results, we performed quantitative real-time RT-PCR (qRT-PCR) on a subset of DEGs. Enrichment analysis using DAVID was performed on DEGs to identify enriched Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways and biological process gene ontologies (GO:BP). qRT-PCR results significantly predicted RNA-seq results. RNA-seq revealed that most DEGs identified in the CORT model overlapped with the CID model. Enrichment analyses identified KEGG pathways and GO:BP terms associated with ion homeostasis and neuronal communication for both the CORT and CID model. In addition, CID DEGs were enriched in pathways and terms relating to neuronal development, intracellular signaling, learning and memory. This study is the first to investigate CID at the mRNA level. We have shown that most hippocampal mRNA changes that are associated with a depressive-like state are also associated with cancer. Several other changes occur at the mRNA level in cancer, suggesting that the CID model may represent a biologically distinct form of a depressive-like state.

The association between biological rhythms, depression, and functioning in bipolar disorder: a large multi-center study.

OBJECTIVE: We examined the relationship between biological rhythms and severity of depressive symptoms in subjects with bipolar disorder and the effects of biological rhythms alterations on functional impairment. METHOD: Bipolar patients (n = 260) and healthy controls (n = 191) were recruited from mood disorders programs in three sites (Spain, Brazil, and Canada). Parameters of biological rhythms were measured using the Biological Rhythms Assessment in Neuropsychiatry (BRIAN), an interviewer administered questionnaire that assesses disruptions in sleep, eating patterns, social rhythms, and general activity. RESULTS: Multivariate analyses of covariance showed significant intergroup differences after controlling for potential confounders (Pillai's F = 49.367; df = 2, P < 0.001). Depressed patients had the greatest biological rhythms disturbance, followed by patients with subsyndromal symptoms, euthymic patients, and healthy controls. Biological rhythms and HAMD scores were independent predictors of poor functioning (F = 12.841, df = 6, P < 0.001, R2  = 0.443). CONCLUSION: Our study shows a dose-dependent association between the severity of depressive symptoms and degree of biological rhythms disturbance. Biological rhythms disturbance was also an independent predictor of functional impairment. Although the directionality of this relationship remains unknown, our results suggest that stability of biological rhythms should be an important target of acute and long-term management of bipolar disorder and may aid in the improvement of functioning.

Val66Met polymorphism and serum brain-derived neurotrophic factor in bipolar disorder: an open-label trial.

OBJECTIVE: Brain-derived neurotrophic factor (BDNF) is consistently associated with acute mood episodes in bipolar disorder, but there is a lack of longitudinal data to support this hypothesis. In this 16-week open-label clinical trial, we tested the predictive role of BDNF Val66Met polymorphism on serum BDNF levels and the relationship of serum BDNF and clinical response in people with bipolar disorder during an acute illness episode. METHOD: Sixty-four people with bipolar disorder who were medication-free at baseline and in an acute mood episode were recruited. They were matched with 64 healthy controls. Clinical evaluation, serum BDNF, and BDNF Val66Met polymorphism were determined at baseline, and change in serum BDNF was assessed in patients at weeks 2, 4, 8 and 16. RESULTS: There were no differences between patients and controls in serum BDNF or in frequencies of the BDNF Val66Met polymorphism genotype at baseline. The multivariable model showed that Met carriers had a significantly different change in BDNF levels compared with Val homozygotes. Not achieving a complete remission was also associated with lower prospectively assessed BDNF levels. CONCLUSION: This study provides the first longitudinal evidence that both the BDNF Val66Met polymorphism and remission status predict change in circulating BDNF levels.

The clinical implications of cognitive impairment and allostatic load in bipolar disorder.

BACKGROUND: Allostatic load (AL) relates to the neural and bodily "wear and tear" that emerge in the context of chronic stress. This paper aims to provide clinicians with a comprehensive overview of the role of AL in patophysiology of bipolar disorder (BD) and its practical implications. METHODS: PubMed searches were conducted on English-language articles published from 1970 to June 2011 using the search terms allostatic load, oxidative stress, staging, and bipolar disorder cross-referenced with cognitive impairment, comorbidity, mediators, prevention. RESULTS: Progressive neural and physical dysfunction consequent to mood episodes in BD can be construed as a cumulative state of AL. The concept of AL can help to reconcile cognitive impairment and increased rates of clinical comorbidities that occur over the course of cumulative BD episodes. CONCLUSIONS: Data on transduction of psychosocial stress into the neurobiology of mood episodes converges to the concept of AL. Mood episodes prevention would not only alleviate emotional suffering, but also arrest the cycle of AL, cognitive decline, physical morbidities and, eventually, related mortality. These objectives can be achieved by focusing on effective prophylaxis from the first stages of the disorder, providing mood-stabilizing agents and standardized psychoeducation and, potentially, addressing cognitive deficits by the means of specific medication and neuropsychological interventions.

[Mycoplasma pneumoniae pneumonia: clinical and radiological features] / Diferentes apresentações clínico-radiológicas da pneumonia.

OBJECTIVE: To alert about the great variability of clinical and radiological features of Mycoplasma pneumoniae pneumonia in pediatric patients. Although it has been referred as a prevalent entity in children, its diagnosis is, many times, retarded due to the lack of a pattern that can really be considered classic.METHODS: The authors present 5 cases of mycoplasma pneumonia in children. Diagnostic difficulties, clinical features, radiological findings and evolution after treatment are discussed. The cases have their significant peculiarities confronted with the findings of medical literature of the last two decades, obtained through a bibliographic research in Medline about the subject.RESULTS: All the patients were between 6 and 9 years old, characteristically the most prevalent age group for this infection. In none of the cases the possibility of mycoplasma infection was considered at first. Clinical hypothesis like sinusal aspirative pneumonia, tuberculosis, and asthma were initially considered, but later on discarded. Except for one, all the other patients referred previous treatment with antibiotics. The initial radiological findings were different among the cases: bronchopneumonic consolidations, pleural effusion, perihilar adenopathy with interstitial infiltrated, and atelectasic areas. After the institution of specific therapy, clinical and radiological evolution was favorable in all cases.CONCLUSIONS: Mycoplasma pneumoniae pneumonia has a great sort of clinical presentations. In the same way the complementary radiological investigation may also demonstrate different patterns of presentation. Due to its great variability, mycoplasma is not commonly considered as the first diagnosis, even though it is a prevalent disease at pediatric age. This may lead to a delay in the diagnosis and institution of an appropriate treatment.
