Morphology of placental villi after premature delivery and its clinical relevance
1986
Based on a new concept of maturation of the placental villous tree and its disorders (synchronous and asynchronous immaturity, asynchronous maturity, hyperpermaturity, and terminal villi deficiency) we studied the possible effect of the placental villous tree on the premature onset of labour. In mature normal neonates irregular and asynchronous villous patterns were found in 50% of cases. In prematurely delivered neonates, only 33% of the corresponding placentas show synchronous immature villous patterns. Uterine bleeding in the first trimester was associated with a 42% of incidence of premature maturation of the villous tree. These findings strengthen the idea that hormonal imbalance in ea…
67 The effect of hypertensive disorders of pregnancy on the risk of attention-deficit/hyperactivity disorder in the offspring
2016
Introduction Attention-deficit/hyperactivity disorder (ADHD) is a frequent neurodevelopmental disorder. Inadequate placentation as a result of hypertensive disorders of pregnancy has been proposed to be a central mechanism of fetal neurodevelopmental comprise. Recently it has been shown that pre-eclampsia increases the risk of ADHD [Mann and McDermott, 2011] . Objectives We examined the association between hypertensive disorders of pregnancy and ADHD and behavioural difficulties among 7-year old children. We also examined whether circulating factors in serum from women with a HDP alter early patterns of fetal neural growth. Methods The study cohort consisted of 13,192 children (weighted = 1…
Artrial Natriuretic Peptide Concentrations in Preeclampsia
1989
During pregnancy various humoral and functional mechanisms were recognized, that regulate the water and electrolyte household. In preeclampsia, increased water-sodium retention results from a variety of pathophysiological changes in the endocrinological system. There are also organ-specific changes, such as renal clearance reduction up to 30% in comparison to normal pregnancy. For many years, physiologists expected to find additional cardial mechanisms that influence homeostasis. In 1981, de Bold [3] identified ANP a new humoral factor that leads to increased water and sodium excretion. The influence of ANP in preeclampsia has been the subject of controversial discussion.
Zirkadiane Blutdruckrhythmik bei der Präeklampsie: Ein Prädiktor für die maternale und geburtshilfliche Situation?
2003
Background Preeclampsia is a pregnancy-induced multiorganic disease. The incidence is 5 - 7 % in all pregnant women. To assess the value of circadian blood pressure rhythm in preeclamptic women, 24-hour blood pressure monitoring might be useful. The purpose of this study was to determine the predictive value of circadian blood pressure rhythm for the maternal and obstetrical outcome in patients with mild preeclampsia. Patients and methods Sixty-six patients with mild preeclampsia underwent 24-hour blood pressure monitoring between 29 and 39 weeks gestation. Twenty-eight patients with normal circadian blood pressure rhythm were compared with thirty-eight patients with suspended circadian blo…
Acute estradiol protects CA1 neurons from ischemia-induced apoptotic cell death via the PI3K/Akt pathway
2010
Global ischemia arising during cardiac arrest or cardiac surgery causes highly selective, delayed death of hippocampal CA1 neurons. Exogenous estradiol ameliorates global ischemia-induced neuronal death and cognitive impairment in male and female rodents. However, the molecular mechanisms by which a single acute injection of estradiol administered after the ischemic event intervenes in global ischemia-induced apoptotic cell death are unclear. Here we show that acute estradiol acts via the phosphoinositide 3-kinase (PI3K)/protein kinase B (Akt) signaling cascade to protect CA1 neurons in ovariectomized female rats. We demonstrate that global ischemia promotes early activation of glycogen syn…
Giant enchondroma recurrence of the proximal phalanx of the fifth finger: A case report
2020
Enchondroma (EC) is a benign and cartilage-forming tumor that causes intramedullary lesions. Moreover, EC is the most common bone tumor in the phalanges and metacarpal bones of the hand, deforming the structure and causing pain and functional limitation. The management of this neoplasia is the surgical treatment and the approach that is well-accepted consists in the curettage followed by the void augmentation with biological or synthetic fillers. The results from surgery are usually good and the recurrence rate is low (2-15%). In this article we report a case of EC recurrence of the proximal phalanx of the fifth finger of the hand after curettage and grafting. The patient was treated with t…
Efficacy and predictors of outcome of short-term psychodynamic psychotherapy (stpp) in depressed breast cancer patients: A randomised controlled trial
2013
Results: 34 people made up the data set. 25/34 (74%) answered the questionnaire. 11/25(44%) had suicidal thoughts in the previous 72 hours. 3/34 (9%) had deliberately self-harmed in the previous 72 hours. 29/34 (85%) stated that the needle exchange would be their first contact point in health care if they had concerns over theirmental health. Qualitative data revealed drug workers are providing mental health support to service users, but haven’t received formal training. Discussion: This is a small study limited by questionnaire design and sample size. However, it does highlight some important points. Namely, drug users remain at higher risk of suicide ideation and selfharm than general pop…
Moderate and severe depression
2000
Background: Despite its importance, no distinction between moderate and severe depression using the Montgomery–Asberg Depression Rating Scale (MADRS) based on a direct comparison with the Hamilton Depression Rating Scale (HAMD-17) is available. Methods: HAMD-17 and MADRS ratings from N=40 at least moderately depressed inpatients with major depression (DSM-III-R) were analyzed. Linear and non-parametric correlations were computed and a MADRS cut-off score for severe depression using an HAMD-17 score of at least 28 points as reference was estimated. Results: HAMD-17 and MADRS mean scores were 24.6±4.3 and 32.6±5.0 points, respectively. Linear correlation of both scores was r=0.70 (P<0.0005). …
A common role for psychotropic medications: memory impairment.
2002
Summary The psychopathologic profile of mental disorders is very diverse and psychotropic medications used to treat them differ in their chemical structure. Nevertheless, these drugs share these four characteristics: delayed onset of clinical response, not one of them can be said to cure, there is a high number of non-responders, and the mechanism responsible for their therapeutic action is not known. It is hypothesized that the action of psychotropic medications is memory impairment, understanding memory as the trace left in the nervous system not only by individual experiences but also by genetic and epigenetic phenomena. It is suggested that it would be beneficial to translate some resea…
Explaining self-reported traffic crashes of cyclists: An empirical study based on age and road risky behaviors
2019
Abstract The growing rates of traffic crashes involving cyclists are currently recognized as a major public health and road safety concern. Furthermore, risky behaviors on the road and their precedent factors have been conceptualized as potential determinants for explaining, intervening and preventing traffic injuries of cyclists. Objectives This study aimed at examining whether individual factors and self-reported risky behaviors could explain the crash rates of cyclists in a period of 5 years. Methods A sample of 1064 cyclists was used, with a mean age of 32.83 years. Participants answered a survey assessing demographic data and information on risky behaviors, risk perception, knowledge o…
