[Immune-inflammatory and autoimmune mechanisms in postpartum depression].

Postpartum depression is a debilitating mental disorder with a high prevalence, usually related with a past psychiatric history of major depressive disorder, postpartum depression, bipolar disorder, premenstrual syndrome (PMS), and perinatal depressive symptoms during gestation. However, the existing literature does not sufficiently elucidate the pathophysiology of this clinical entity which appears in such a crucial period of woman's life. This review aims to search the available data regarding the involvement of immunological and autoimmune mechanisms in its onset. A literature review was conducted using web-based search engines provided by PubMed (for Medline database) and Google Scholar. Manuscripts in English and Greek language were included for the period 19902017. Nowadays, a large body of evidence indicates that depressive disorders are accompanied by activated neuro-immune, neuro-oxidative and neuro-nitrosative stress (IO&NS) pathways. However, clinical research regarding the biological mechanisms associated with PPD is a tough challenge as pregnancy and puerperium are periods of adaptive changes in pregnant women by definition. Two of the systems that have been studied as potentially contributing to the onset of PPD are: the activation of the Inflammatory Response System (IRS) and the deregulation of the Hypothalamic-PituitaryAdrenal axis (HPA). Controversial data indicate dysregulation of cytokines and other inflammatory agents in patients with PPD, as well as, a close correlation of immune-inflammatory mechanisms and kynurenine pathway. PPD has been closely associated with autoimmune diseases. It is notable that this entity shares many common traits with autoimmune diseases such as the genetic susceptibility, family history, the high correlation with other autoimmune diseases, clinical exacerbations and remissions, women's superiority in prevalence, and the possible re-occurrence during a future pregnancy. These facts suggest that the typical postpartum flare pattern, and other clinical characteristics, point towards an autoimmune etiology for PPD. There are indications that immune-inflammatory and autoimmune mechanisms may be the key to deciphering the complex pathophysiological pathways associated with the onset of PPD. Clinical studies have been insufficient to make clear the causative correlations of the underlying mechanisms involved. Future research could focus on the immune-inflammatory processes associated with the onset of the disease, as well as on potential biomarkers for an early diagnosis and an effective treatment of PPD.

Carbapenemase-producing Klebsiella pneumoniae bloodstream infection in critically ill patients: risk factors and predictors of mortality.

A significant increase in carbapenemase-producing Klebsiella pneumoniae (CP-Kp) bacteraemias has been observed worldwide. The objective of the present work was to study the risk factors and predictors of mortality of CP-Kp bacteraemias among critically ill patients. During a 4-year period (2012-3015), a matched 1:2 case-control study was conducted. Klebsiella pneumoniae was identified by Vitek 2 technology. Antibiotic susceptibility was performed by the agar disc diffusion method and Etest. The presence of the bla KPC, bla VIM and bla NDM genes was confirmed by polymerase chain reaction (PCR). Epidemiologic data were collected from the intensive care unit (ICU) computerised database. One hundred and thirty-nine patients who developed a CP-Kp bacteraemia were matched with 278 patients. The majority of isolates (128; 92.1%) carried the bla KPC gene, seven carried both bla KPC and bla VIM, three bla VIM and one carried bla NDM. Risk factors for the development of CP-Kp bacteraemia were administration of tigecycline and number of antibiotics administered prior to CP-Kp bacteraemia. Overall, the 30-day mortality was 36.0%. Multivariate analysis revealed septic shock, Simplified Acute Physiology Score II (SAPS II) upon infection onset, adjunctive corticosteroid administration and parenteral nutrition as independent predictors of mortality, while treatment with a combination of appropriate antibiotics was identified as a predictor of good prognosis. Among septic shock patients (n = 74), Sequential Organ Failure Assessment (SOFA) score upon infection onset, adjunctive corticosteroid administration and strain carrying the bla KPC gene were independently associated with mortality, while the administration of combination treatment was identified as a predictor of a good prognosis. The administration of tigecycline predisposes to the induction of bacteraemia. Appropriate antibiotic treatment is associated with better survival, while concomitant corticosteroid treatment is associated with mortality.

Circulating androgens are associated with mood disturbances in young postmenopausal women.

OBJECTIVES: We aimed to evaluate the association between circulating androgens and the presence of psychological symptoms in a sample of healthy middle-aged women. METHODS: Psychological and depressive symptoms were evaluated in a total of 207 postmenopausal women, using the Symptom Checklist-90-R (SCL-90R) and the Zung Depression Scale, respectively. We investigated the associations between the SCL-90R and Zung Scale scores, and anthropometric, lifestyle parameters, as well as serum levels of androgens. RESULTS: The free androgen index was positively associated with scores of depression (b-coefficient ± standard error (SE) = 0.2 ± 0.2, p = 0.040), anxiety (b-coefficient ± SE = 0.2 ± 0.2, p = 0.028), anger/aggressiveness (b-coefficient ± SE = 0.3 ± 0.2, p = 0.026), psychotism (b-coefficient ± SE = 0.3 ± 0.1, p = 0.013) as well as with the global index of the SCL-90R scale (b-coefficient ± SE = 0.2 ± 0.1, p = 0.036), while sex hormone binding globulin was negatively associated with depression (b-coefficient ± SE = -0.2 ± 0.0, p = 0.046) and psychotism (b-coefficient ± SE = -0.2 ± 0.0, p = 0.047). These associations were independent of vasomotor symptomatology, smoking and hormone therapy intake and were more pronounced in younger (≤ 5.5 years) compared to older postmenopausal women. Levels of dehydroepiandrosterone sulfate were positively associated with interpersonal sensitivity (b-coefficient ± SE = 0.3 ± 0.3, p = 0.042), psychotism (b-coefficient ± SE = 0.4 ± 0.2, p = 0.007) and the global index (b-coefficient ± SE = 0.3 ± 0.2, p = 0.040) in women < 5.5 years postmenopausal. No significant associations were observed between the Zung or Greene Scale scores and levels of androgens. CONCLUSION: Higher androgenicity was positively associated with symptoms of anxiety and depression in postmenopausal women. These associations were stronger in women closer to the menopausal transition, a finding which may suggest that menopause rather than aging may mediate the association of androgens with mood disorders.

Psychological but not vasomotor symptoms are associated with temperament and character traits.

OBJECTIVE: Recent evidence suggests that climacteric symptoms may be intensified by specific temperament and personality traits in postmenopausal women. In this study we investigate Cloninger's model of personality in relation to menopausal symptoms. METHODS: One-hundred and seventy peri- and postmenopausal women consecutively recruited from a menopause clinic of an academic hospital completed the Cloninger's Temperament and Character Inventory (TCI-140) which measures four dimensions of temperament: Harm avoidance, Novelty seeking, Reward dependence and Persistence, as well as three dimensions of character: Self-directedness, Cooperativeness, and Self-transcendence. Menopausal somatic, vasomotor and psychological symptoms were also assessed using the Greene Climacteric Scale. RESULTS: In comparison to the norms of the Greek general population, postmenopausal women presented lower scores in Novelty seeking and Reward dependence and higher scores in Persistence, Self-directedness, Cooperativeness and Self-transcendence. Higher harm avoidance (the inclination to avoid potential punishment, be shy and fearful of uncertainty) significantly correlated with anxiety and depressive symptoms while lower Self-directedness (the ability to have the willpower to adapt to or overcome any changes) correlated with depressive symptoms only. By multivariate regression analysis, higher Harm avoidance and lower Self-directedness were independently associated with the presence of depressive symptoms. No significant associations were observed between TCI-140 traits and somatic or vasomotor symptoms. CONCLUSIONS: Our findings indicate that most temperament and character traits according to Cloninger's model in peri- and postmenopausal women varied significantly as compared to the general population. Among several traits, high Harm avoidance and low Self-directedness were most strongly associated with psychological climacteric distress but not with somatic and vasomotor symptoms.

[Parenting capacity of mothers with schizophrenia].

Recent studies indicate that the pregnancy rates of mothers with schizophrenia do not differ significantly from those of the general population. Mothers' severe mental illness, combined with poor social support and comorbidity, may significantly affect her parenting capacity. However, the poor quality of parenting by psychotic mothers should not be taken for granted, in advance. Some of them may become excellent parents while other may abuse their children and finally lose custody because of this. The parenting capacity is significantly influenced by the existing insight of patient-parent's disease. Assessing the parenting capacity comprises the measurement of insight and of the risk of child abuse as well. Factors associated with increased risk for child abuse are: (a) active psychiatric symptomatology, (b) history of violent behavior in the past, (c) maternal history of abuse during childhood, (d) dangerous domestic environment, (e) stressful events and poor social support to the mother and (f) unrealistic parental expectations. These factors should be assessed both clinically and by using the appropriate psychometric tools. Tools which have been widely used for this purpose are: (a) "Schedule for Assessment of Insight-SAI", (b) "Childhood Trauma Interview", (c) "Home Observation for the Measurement of the Environment Inventory-HOME" and "Home Screening Questionnaire -HSQ", (d) "Parental Stress Inventory-PSI", "Swedish Parenthood Stress Questionnaire-SPSQ", "Arizona Social Support Inventory" (e) "Parent Opinion Questionnaire-POQ". Interventions to ensure a more adequate parenting capacity should be focused on family planning: mothers with severe mental illness have poor knowledge about reproductive and contraception issues. Their pregnancies are mostly not planned. It is important for the family planning to be tailored according to the specific needs of schizophrenic mothers and to take into account the following issues: (a) the severity and the duration/chronicity of the disease, (b) the onset of the disease in relation to the gestational period, (c) the education of mothers with schizophrenia considering their double patient/mother role. An educational program should train the mother to recognize early signs of the disease, comply with medication, increase her empathy towards the baby and reduce any distorted perceptions about it. The treating, assessing, educating and preventing programs and interventions of mental health services should be continuous and supportive.

[Cosmetic breast augmentation and suicide risk: a puzzling association].

The goal of the present article is to examine the unexpected association between cosmetic breast augmentation and suicide found in recent epidemiological investigations. During the last decade, seven epidemiological studies coincide in the high risk of suicidality among women with breast implants. More specifically, the rate of suicide among these patients appears doubled or tripled than expected in the general population. The absence of etiological answers that could interpret this association remains a serious limitation in this field of research. However, the preoperative psychopathology among women with breast implants, their motives and expectations, and their psychosocial characteristics are important factors that may contribute in the relationship between cosmetic breast augmentation and risk of suicide. Body image disorders, most common of which is the body dysmorphic disorder, along with high rates of depression and anxiety disorders are psychopathologic features found in a substantial number of cosmetic breast implant patients. Possible future research directions are proposed, in order to better understand the relationship between breast augmentation and suicide. In the meantime, the consistency of epidemiologic results on the high risk of suicide among breast implant patients suggests the need for interdisciplinary collaboration between plastic surgeons and mental health professionals, at least for those breast implant patients who present with preoperative psychopathology.

[A study of irritability in menopausal women].

Despite the fact that irritability is frequently the main presenting complaint of perimenopausal and postmenopausal women, studies specifically researching irritability in this population are scant. One hundred sixty three (163) peri- and postmenopausal women non-HT users, attending a menopause clinic, were included in this cross-sectional study. The investigation focused on whether the occurrence of inward and outward irritability in menopause is associated with various menopausal parameters, such as vasomotor symptoms, insomnia, menopausal status, hormone levels, and with the presence of chronic disease. Furthermore, we examined the possible association of inward and outward irritability with measures of anxiety and depression. Outward and inward irritability of peri- and postmenopausal women seem to be related to chronic disease, a factor that may be partially influenced by the older age of menopausal women. Outwardly directed irritability is found to be related to FSH and LH levels, independently of specific menopausal symptoms, such as vasomotor symptoms or insomnia. Outward irritability was found to be positively correlated with depressive symptomatology, whereas inward irritability correlated with both anxiety and higher depressive symptomatology.

Hip dysplasia following a case of olanzapine exposed pregnancy: a questionable association.

This is a case report of a 33 year old woman with a history of psychosis, who presented to the women's mental health clinic for consultation at the 12(th) week of gestation, having already received olanzapine throughout the first trimester. She was followed from that point on at our clinic and remained on small doses of olanzapine for the rest of her pregnancy, which was uncomplicated. She gave birth to a healthy female, which at the age of three months was diagnosed with developmental dysplasia of the hip and subsequently received appropriate treatment with favorable outcome. The possibility of the association of this congenital dysplasia with the use of olanzapine during pregnancy is further discussed in this paper.

Cord blood erythropoietin in the presence and absence of labor in normal infants.

To evaluate erythropoietin (Ep) levels in normal labor and cesarean section we studied the cord serum of 111 term pregnancies, divided into three groups: (i) those born by normal vaginal delivery (n = 69); (ii) those delivered vaginally from mothers who were smokers (n = 20); and (iii) those delivered by elective cesarean section (n = 22). The three groups did not differ in maternal age, gestational age, birthweight, infant sex and Apgar scores. No correlation was found between Ep and hematocrit in all three groups of normal terms studied. Although not statistically significant the lower mean Ep value observed in cesarean section compared with the values obtained from normal deliveries could suggest that the process of labor may be a cause of these differences.
