The outcome of 3,199 women booked for delivery in six general-practitioner obstetric units in one year was analyzed.Five per cent cancelled their bookings, 26 per cent were transferred to a consultant unit after referral for routine problems of pregnancy (mainly postmaturity), and 14 per cent were transferred for problems arising in labour (principally uterine inertia). One per cent were transferred after confinement.Fifty-four per cent were delivered successfully in the general-practitioner units.There were 3,037 live births, 27 stillbirths and 22 neonatal deaths. Nine stillbirths and nine neonatal deaths resulted from congenital abnormalities, while two stillbirths and 11 neonatal deaths were due to immaturity. There were 25 sets of twins and one set of triplets. Seventy-five babies were abnormal, 105 weighed less than 2,500g, and 198 over 4,000g.In this series almost 60 per cent of eventual perinatal deaths were transferred during pregnancy, and over 85 per cent before delivery.The perinatal mortality of all women initially booked for a general-practitioner unit who delivered was 15.. The perinatal mortality of the 1,795 births in the six general-practitioner obstetric units was 3.9.

Ninety-five men, selected in college on the basis of health have been prospectively followed up for 30 years. Their adaptive styles have been isolated, labeled by the ego mechanisms of defense that their behavior reflects, and studied by semiquantitative techniques. A hierarchy of ego mechanisms was devised that ordered defenses along a continuum that reflected the following two dimensions: (1) immaturity-maturity and (2) psychopathology-mental health. The most important finding was that despite blind assessment, a scale reflecting the maturity of a subject's defenses correlated with scales measuring his objective psychopathology (r = -.35) and his objective adaptation to the external environment (r = .65). Highly significant shifts in defensive style occurred as individuals matured. In order to conceptualize the continuum that underlies mental health, identification of a person's dominant defensive styles may be superior to our current scheme of static unitary diagnoses.

As a result of long-term clinical research on former prisoners of the Nazi concentration camps, I analyzed the evolution of the clinical and psychopathological pattern of the KZ-syndrome. One can differentiate the following characteristic phases: psychosomatic inanition, latency of disease, personality and adaptation disturbances, a pseudo-neurotic and depressive phase, premature aging, and an organic phase. The stigma of KZ-syndrome is present in a second generation in different forms: personality disturbances, emotional and/or social immaturity, social disadaptation, higher frequency of neurotic states, divorce, alcoholism, and suicide. The camp stress has left in human nature traces so painful that they cannot disappear when the generation of former prisoners is gone.

Effects of beta-agonists isoproterenol (Isp) and adrenaline (Adr) and beta-adrenoblocker obsidan (Obs) on the voltage-dependent calcium currents in cultured embryonic skeletal myocytes were studied at various stages of development ranging from day 2 to 10, using the whole-cell patch-clamp technique at 19-21 degrees C. Adr (or Isp) in concentrations 0.1-10 mumol/l increases the amplitude of both the slow dihydropyridine(DHP)-sensitive calcium current (ICa) and the fast-activated DHP-insensitive ICa. From day 2 to 6 after myoblast plating, Adr and Isp did not change the amplitude of ICa at all or slightly increased it. Obvious strong positive effects (an approximately twofold amplitude increase) on the calcium channels have been observed in 7-10-day-old myocytes only. beta-adrenoblocker obsidan known to abolish the positive beta-agonist effect, had a positive effect on membrane calcium currents. It may have been a result of the immaturity of the beta-adrenergic regulatory system of the myocytes. It is concluded that the beta-adrenergic regulatory complex can stimulate the activity of the fast and the slow voltage-dependent calcium channels of the frog skeletal myocytes, and that there is a distinct developmental stage at which a functioning beta-adrenergic regulatory complex appears in the membrane of skeletal myocytes.

Variations in levels of motivation to learn among established general practitioners (GPs) have received scant attention. Building on previous work, we present an analysis of factors contributing to the development of motivation to learn in those who are entering and already established in practice. This approach suggests that individual motivation is both complex and unstable in response to external factors. We draw attention to the possibility of motivational immaturity in recruits to general practice, the contribution of values, and the presence of demotivators. The implications of our analysis are explored in relation to individual professional development and continuing education provision. We suggest that motivational audit will identify individual and contextual factors that are reducing the capacity of GPs to continue learning. A number of approaches addressing these factors are proposed.

The objectives of this study were to do inexpensive lamellar body count (LBC) in amniotic fluid, to do statistical analysis to evaluate cutoff values for fetal lung maturity (FLM) and fetal lung immaturity (FLI), to derive a threshold for obtaining a lecithin-to-sphingomyelin (L/S) ratio and phosphatidylglycerol percentage (%PG), and to determine the potential cost savings to the hospital if they use this new method. Testing (LBC, L/S ratio, and %PG) was done on 123 specimens of amniotic fluid. Receiver operating characteristic (ROC) curve, discriminant, linear regression, chi2, and cost analyses were used to evaluate the laboratory and financial parameters. Lamellar body counts of greater than 41,500 (Coulter MAXM: sensitivity, 90.5%; specificity, 87.7%; positive predictive value, 79.2%; negative predictive value, 94.7%) and greater than 32,000 (Coulter Gen.S: sensitivity, 90.5%; specificity, 85.2%; positive predictive value, 76.0%; negative predictive value, 94.5%) were the best threshold for biochemical FLM. Similarly, LBC of less than 24,000 (MAXM: sensitivity, 78.6%; specificity, 100%; positive predictive value, 100%; negative predictive value, 90.0%) and less than 21,000 (Gen.S: sensitivity, 71.4%; specificity, 100%; positive predictive value, 100%; negative predictive value, 87.1%) provided the best statistical cutoff for biochemical FLI from discriminant analysis. The authors concluded that FLM and FLI can be predicted with reasonable accuracy from LBC in amniotic fluid specimens. The expensive and not easily accessible L/S ratio and %PG can then be done only in cases in which LBC indicates transitional FLM. A cascade approach results in 86% savings to the hospital if the L/S ratio and %PG are not sent to a reference laboratory.

The project seeks to identify genes involved in key stages of trout spermatogenesis and their regulation. Within the framework of the French project of farm animal genomics (AGENAE) we produced an original normalised trout testis cDNA library and obtained 1152 trout ESTs corresponding to 967 potential genes. To study the expression of those genes throughout first stages of spermatogenesis, we used nylon macroarray. Gonads in stage of immaturity (stage I), or at initiation of spermatogonial proliferation (stage II), meiosis (stage III) or spermiogenesis were selected by histological analysis. Total RNA was extracted and then used to produce complex targets labelled with [33P]dCTP and hybridised with cDNA arrays. After filtering and normalisation of hybridisation signals, genes presenting differential expression as revealed by ANOVA analysis were submitted to k-means clustering and hierarchical classification. Genes were separated into five clusters which presented distinct profiles. One cluster overexpressed in stage I could be involved in the initial events of spermatogenesis as seminiferous tubule organisation. The second cluster displays a transient increase at the beginning of testicular recrudescence (stage II). Three other clusters group several genes involved in cell proliferation and protein synthesis and modification. One is particularly down-expressed during stage I, the two others show increased expression during stages III and IV and appear to be involved in spermatogonial and meiotic proliferation and in protein metabolism linked to cellular growth. This allows us to plan further experiments to better understand the functional implication of some of the genes that are found to be significantly regulated like CDC2, hematological and neurological expressed gene 1-like protein, HCDI protein, Mago Nashi, a BMP-like, and a steroid receptor binding protein. These data demonstrate the applicability of the array based technology using our trout cDNA arrays and highlight genes that are potential targets for the control of puberty and fertility in farmed fish.

Five types of gonadotropin-releasing hormone receptor (GnRH-R) genes, designated as msGnRH-R1, R2, R3, R4, and R5, are expressed in the brain and pituitary of masu salmon (Oncorhynchus masou). In the present study, seasonal changes in the expression of these five genes were examined in the pituitary to elucidate their roles in GnRH action during growth and sexual maturation. In addition, the seasonal variation of these genes in response to GnRH was examined in a GnRH analog (GnRHa) implantation experiment. Pituitary samples were collected 1 week after the implantation every month from immaturity through spawning. The absolute amount of GnRH-R mRNA in single pituitaries was determined by real-time PCR assays. Among the five genes, R4 was predominantly expressed in the pituitaries. In the immature fish, the amount of GnRH-R mRNA varied with seasons and subtypes. In the pre-spawning period, R1 and R4 mRNAs in both sexes and R2 and R3 mRNAs in the females increased 4- to 20-fold and then decreased in the spawning season. The effects of GnRHa treatment were significantly different in both sexes. In the females, GnRHa tended to elevate the expression of all the subtypes of GnRH-R genes in various stages during the experimental period, whereas it had almost no apparent effects in the males. These results indicate that the expression of the five GnRH-R genes is seasonally variable and may be related to the responses of the pituitary hormone genes to GnRH, and the regulation of GnRH-R genes by GnRH is different in both sexes.

Nonconserving children may fail to conserve because of difficulties in verbally expressing nonlinguistic knowledge of equivalence relationships. This may be partly due to an inability of the right hemisphere, which mediates the performance of internal reversals and conservation, to communicate with the speaking left hemisphere because of the immaturity of the corpus callosum. This relationship presumably results in the asymmetrical activation of the left hemisphere when verbal responses are required. To assess the possibility that nonconservers have an awareness of the reversibility of these operations, three groups of nonconserving children (N = 42) were either asked which of two containers (one of which appeared to contain more liquid, but had previously been shown to contain less) had more in it, or which (pretending they were very thirsty and it was their favorite drink) they would prefer. To assess whether nonconservers respond primarily with left hemisphere activation, patterns of lateral eye movement in response to verbal-analytic or spatial-emotional stimuli were obtained in a fourth group (N = 37). Both hypotheses were supported.

The management of cardiopulmonary bypass for pediatric cardiac surgery is more challenging than that in adults due to the smaller size, immaturity, and complexity of the anatomy in children. Despite major improvements in cardiopulmonary bypass, there remain many subjects of debate. This review article discusses the physiology of cardiopulmonary bypass for pediatric and congenital heart surgery, including topics related to hemodilution, hypothermia, acid-base strategies, inflammatory response, and myocardial protection.
