Maternal Identity Change as a Consequence of Antenatal Hospitalization

Despite low fertility rates in Western countries, maternity remains one of the major goals of women from various socioeconomic backgrounds. While most women will have low-risk pregnancies, common serious disorders of pregnancy, such as preeclampsia, premature rupture of the membranes, placenta previa, or fetal growth restriction, may compromise maternal and infant outcomes. The experiences of urban and rural women in Australia who have had difficulties in maintaining their pregnancies are analyzed in this article. We study the impact of individual and social factors that facilitate or impede women's adjustment to the risks associated with these disorders. The analysis of in-depth interviews with 27 women hospitalized antenatally indicates that most women were unfamiliar with the diagnoses and acted as passive “decision takers,” complying with medical advice to remain in the hospital. Admission to a tertiary hospital ward that provided care to women with pregnancy disorders promoted the formation of a new identity, that of a woman whose pregnancy did not follow the expected path. Further, hospitalization offered women the opportunity to interact with others in similar difficult situations and, hence, feel less isolated.     

Prooxidant–antioxidant balance,hsTnI and hsCRP: mortality prediction in haemodialysis patients,two-year follow-up

Oxidative stress and inflammation are highly intertwined pathophysiological processes. We analyzed the markers of these processes and high-sensitive troponin I (hsTnI) for mortality prediction in patients on haemodialysis. This study enrolled a total of 62 patients on regular haemodialysis. The patients were monitored for two years, and the observed outcomes were all-cause and cardiovascular mortality. Blood samples were taken before one dialysis session for analysis of the baseline concentrations of prooxidant–antioxidant balance (PAB), total antioxidant status (TAS), total oxidative status (TOS), hsTnI, hsCRP and resistin. The overall all-cause mortality was 37.1% and CVD mortality 16.1%. By univariate and multivariate logistic regression, our findings suggest that good predictors of all-cause mortality include hsCRP and PAB (p?p?p?p?p?=?.001). Our data suggest that hsCRP and PAB are very good predictors of all-cause mortality. For CVD complications and mortality prediction in HD patients, the most sensitive parameters appear to be hsTnI and hsCRP.     

On the origin of schizophrenia: Testing evolutionary theories in the post‐genomic era

Considering the relatively high heritability of schizophrenia and the fact that it significantly reduces the reproductive fitness of affected individuals, it is not clear how the disorder is still maintained in human populations at a disproportionally high prevalence. Many theories propose that the disorder is a result of a trade‐off between costs and benefits of the evolution of exclusively human adaptations. There have also been suggestions that schizophrenia risk alleles are accompanied with increase in fitness of affected persons or their relatives in both past and current social contexts. The discoveries of novel schizophrenia‐related genes and the advancements in comparative genomics (especially comparisons of the human genome and the genomes of related species, such as chimpanzees and extinct hominids) have finally made certain evolutionary theories testable. In this paper, we review the current understanding of the genetics of schizophrenia, the basic principles of evolution that complement our understanding of the subject, and the latest genetic studies that examine long‐standing evolutionary theories of schizophrenia using novel methodologies and data. We find that the origin of schizophrenia is complex and likely governed by different evolutionary mechanisms that are not mutually exclusive. Furthermore, the most recent evidence implies that schizophrenia cannot be comprehended as a trait that has elevated fitness in human evolutionary lineage, but has been a mildly deleterious by‐product of specific patterns of the evolution of the human brain. In other words, novel findings do not support previous hypotheses stating that schizophrenia risk genes have an evolutionary advantage.     

Could Spindle Cell Lung Carcinoma be Considered and Treated as Sarcoma, According to its Clinical Course, Morphology, Immunophenotype and Genetic Finding?

The actual nature of spindle cell carcinoma has been debated extensively because of its rarity. It carries a poor prognosis, even when early-stage disease is diagnosed and resected. In view of the rarity and the significance of the histological diagnosis, we report a patient with rapidly progressing spindle cell lung carcinoma with soft tissue metastasis. Diagnosis was confirmed by immunohistochemistry finding. Analysis of the TP53 gene mutations by polymerase chain reaction and DNA sequencing revealed insertion of single thymine resulting in frameshift mutation in the exon 8. Prognosis of spindle cell lung carcinoma might be determined by the sarcoma component of the tumor and, based on that, we wonder if this type of lung carcinoma could be followed-up and treated by strategies for soft tissue sarcomas, because of its rapid, sarcomatous type of growth, beside the properly lung carcinoma oncological treatment.

Mechanical dispersion is associated with poor outcome in heart failure with a severely depressed left ventricular function and bundle branch blocks

Objectives: Bundle branch blocks (BBB)-related mechanical dyssynchrony and dispersion may improve patient selection for device therapy, but their effect on the natural history of this patient population is unknown.

Methods: A total of 155 patients with LVEF?≤?35% and BBB, not treated with device therapy, were included. Mechanical dyssynchrony was defined as the presence of either septal flash or apical rocking. Contraction duration was assessed as time interval from the electrocardiographic R-(Q-)wave to peak longitudinal strain in each of 17 left ventricular segments. Mechanical dispersion was defined as either the standard deviation of all time intervals (dispersion_SD) or as the difference between the longest and shortest time intervals (dispersion_delta). Patients were followed for cardiac mortality during a median period of 33 months.

Results: Mechanical dyssynchrony was not associated with survival. More pronounced mechanical dispersion_delta was found in patients with dyssynchrony than in those without. In the multivariate regression analysis, patients’ functional class, diabetes mellitus and dispersion_delta were independently associated with mortality.

Conclusions: Mechanical dispersion, but not dyssynchrony, was independently associated with mortality and it may be useful for risk stratification of patients with heart failure (HF) and BBB.

• Key Messages

• Mechanical dispersion, measured by strain echocardiography, is associated with poor outcome in heart failure with a severely depressed left ventricular function and bundle branch blocks.

• Mechanical dispersion may be useful for risk stratification of patients with heart failure and bundle branch blocks.

     

Intravascular large B-cell lymphoma as a cause of hypopituitarism: gradual and late reversal of hypopituitarism after long-term remission of lymphoma with immunochemotherapy

Intravascular large B-cell lymphoma (IVL) is a rare generally fatal disease characterized by massive proliferation of lymphoid cells within the small and medium blood vessels. Hypopituitarism has been reported only in a few fatal cases. We describe the clinical course of hypopituitarism as a complication of IVL, successfully treated with immunochemotherapy (cyclophosphamide/doxorubicin/vincristine/prednisone-CHOP) plus Rituximab anti-CD20 humanized antibody). Before immunochemotherapy, basal hormonal analysis and dynamic test for pituitary function were performed in a 67-year-old female with IVL. Endocrinological evaluation of the pituitary function was repeated after complete hematological remission and during the 2 years of follow-up. Multiple pituitary hormone deficiencies were diagnosed before therapy for IVL. Magnetic resonance imaging (MRI) of the pituitary gland showed partially empty sella. The patient was replaced with thyroxine 50 microg/day and prednisone 5 mg/day between the cycles of chemotherapy. After complete hematological remission (6 months after initial diagnosis) reversal of cortisol and gonadotropin deficiency occurred. After 18 months of hematological remission there was further improvement in growth hormone (GH) response to provocative testings (partial GH deficiency), with normalization of somatotropic and thyreotropic axis after 2 years of follow-up. This is the first case of IVL complicated with hypopituitarism, treated with immunochemotherapy which resulted in complete hematological remission and gradual and late reversal of hypopituitarism.     

Cardiovascular risk factors and blood pressure in a primary care unit: Yugoslav Study of the Precursors of Atherosclerosis in School Children (YUSAD)

OBJECTIVES: The presence of cardiovascular risk factors in children may be important in the development of atherosclerosis in adulthood. Adequate control of blood pressure is a cornerstone in atherosclerosis prevention. The aim of the Yugoslav Study of the Precursors of Atherosclerosis in School Children (YUSAD) was to identify risk factors for elevated blood pressure in school children. METHODS: The YUSAD study is a multicentre follow-up study comprised of two cross-sectional surveys conducted five years apart. At baseline, 10-year-old children (3226 boys and 3074 girls [n=6300]) were randomly selected during periodical visits to primary health care centres. The risk factors measured were heart rate, weight, body mass index (BMI), waist-to-hip ratio, grade point average and current smoking status. RESULTS: Significant age and sex differences were identified in systolic blood pressure, diastolic blood pressure and all investigated independent variables. In a multivariate analysis, diastolic blood pressure in 10-year-old boys was directly and significantly related to total cholesterol and height, whereas it was inversely related to weight. At follow-up, in the multivariate model, only BMI was a significant predictor of diastolic blood pressure in boys. In girls at baseline in the multivariate regression analysis, the only significant predictor of diastolic blood pressure was total cholesterol. In 15-year-old girls, diastolic blood pressure was significantly and directly related to BMI and heart rate, whereas it was inversely related to weight. For both 10- and 15-year-old male and female participants, none of the variables by multivariate analysis were a significant predictor of systolic blood pressure. CONCLUSIONS: Age, sex, heart rate, cholesterol and weight are the most important predictors of blood pressure in school children.
