Scandcleft randomized trials of primary surgery for unilateral cleft lip and palate: Speech proficiency at 10 years of age.

BACKGROUND & AIM: To assess consonant proficiency and velopharyngeal function in 10-year-old children born with unilateral cleft lip and palate (UCLP) within the Scandcleft project. METHODS & PROCEDURES: Three parallel group, randomized, clinical trials were undertaken as an international multicentre study by nine cleft teams in five countries. Three different surgical protocols for primary palate repair (Arm B-Lip and soft palate closure at 3-4 months, hard palate closure at 36 months, Arm C-Lip closure at 3-4 months, hard and soft palate closure at 12 months, and Arm D-Lip closure at 3-4 months combined with a single-layer closure of the hard palate using a vomer flap, soft palate closure at 12 months) were tested against a common procedure (Arm A-Lip and soft palate closure at 3-4 months followed by hard palate closure at 12 months) in the total cohort of 431 children born with a non-syndromic UCLP. Speech audio and video recordings of 399 children were available and perceptually analysed. Percentage of consonants correct (PCC) from a naming test, an overall rating of velopharyngeal competence (VPC) (VPC-Rate), and a composite measure (VPC-Sum) were reported. OUTCOMES & RESULTS: The mean levels of consonant proficiency (PCC score) in the trial arms were 86-92% and between 58% and 83% of the children had VPC (VPC-Sum). Only 50-73% of the participants had a consonant proficiency level with their peers. Girls performed better throughout. Long delay of the hard palate repair (Arm B) indicated lower PCC and simultaneous hard and soft palate closure higher (Arm C). However, the proportion of participants with primary VPC (not including velopharyngeal surgeries) was highest in Arm B (68%) and lowest in Arm C (47%). CONCLUSIONS & IMPLICATIONS: The speech outcome in terms of PCC and VPC was low across the trials. The different protocols had their pros and cons and there is no obvious evidence to recommend any of the protocols as superior. Aspects other than primary surgical method, such as time after velopharyngeal surgery, surgical experience, hearing level, language difficulties and speech therapy, need to be thoroughly reviewed for a better understanding of what has affected speech outcome at 10 years. WHAT THIS PAPER ADDS: What is already known on the subject Speech outcomes at 10 years of age in children treated for UCLP are sparse and contradictory. Previous studies have examined speech outcomes and the relationship with surgical intervention in 5-year-olds. What this study adds to the existing knowledge Speech outcomes based on standardized assessment in a large group of 10-year-old children born with UCLP and surgically treated according to different protocols are presented. While speech therapy had been provided, a large proportion of the children across treatment protocols still needed further speech therapy. What are the potential or actual clinical implications of this work? Aspects other than surgery and speech function might add to the understanding of what affects speech outcome. Effective speech therapy should be available for children in addition to primary surgical repair of the cleft and secondary surgeries if needed.

Improved adherence with PTH(1-84) in an extension trial for 24 months results in enhanced BMD gains in the treatment of postmenopausal women with osteoporosis.

UNLABELLED: The purpose of this study is to examine the effect of PTH(1-84) treatment over 24 months followed by 12 months discontinuation on BMD, bone turnover markers, fractures and the impact of adherence on efficacy. INTRODUCTION: There is limited information about the effect of PTH(1-84) after 18 months and limited data about the impact of compliance on response to anabolic therapy. METHODS: Seven hundred and eighty-one subjects who received active PTH(1-84) in the Treatment of Osteoporosis with Parathyroid hormone trial for approximately 18 months were entered into a 6-month open-label extension. Thereafter, they were followed for 12 additional months after discontinuation of treatment. Endpoints examined included changes in BMD and biochemical markers. RESULTS: PTH(1-84) treatment over 24 months increased BMD at the lumbar spine by 6.8% above baseline (p<0.05).The total corresponding BMD increases at the hip and femoral neck were 1.1 and 2.2% above baseline. Larger increases in spine BMD were observed in participants with ≥80% adherence to daily injections of PTH(1-84) (8.3% in adherent vs 4.9% in poorly adherent patients). Total hip BMD gains were 1.7% in adherent vs 0.6% in poorly adherent participants. Markers of bone turnover (BSAP and NTx) peaked 6 months after starting PTH(1-84) treatment and declined slowly but remained above baseline at 24 months. After discontinuation of PTH(1-84) treatment (at 24 months), bone turnover markers returned to near baseline levels by 30 months. The adherent group sustained significantly fewer fractures than the poorly adherent group. CONCLUSIONS: PTH(1-84) treatment over 24 months results in continued increases in lumbar spine BMD. Adherence to treatment with PTH(1-84) for up to 24 months is also associated with greater efficacy.

The effect of PTH(1-84) or strontium ranelate on bone formation markers in postmenopausal women with primary osteoporosis: results of a randomized, open-label clinical trial.

UNLABELLED: We explored the effects of PTH(1-84) compared with strontium ranelate on bone remodeling as measured by bone remodeling markers in postmenopausal women with osteoporosis. Biochemical markers of bone formation were significantly increased after treatment with PTH(1-84) but not strontium ranelate, indicating a different mechanism of action between these agents. INTRODUCTION: PTH(1-84) and strontium ranelate (SR) are both known to reduce fracture risk in osteoporosis. Measuring changes in biochemical markers of bone turnover induced by these agents can help in characterizing the action of PTH(1-84) and SR on bone remodeling. METHODS: A 24-week, randomized, open-label, parallel group, phase IV trial was conducted in 81 postmenopausal women with primary osteoporosis (≥50 years of age, lumbar spine, or total hip T-score ≤-2.5 SD) to assess the effect of SR as compared to PTH(1-84) on bone formation markers P1NP and BSAP. The bone resorption marker CTX was also measured. Subjects were randomly assigned to receive daily either 100 µg PTH(1-84) (n = 41) (subcutaneous injection) or oral 2 g SR (n = 40) for 24 weeks with daily supplements of 800 IU vitamin D(3) and 1,000 mg calcium. Patient-reported outcomes were collected to investigate the effect of treatment on quality of life (QoL). RESULTS: Percentage changes from baseline in P1NP and BSAP were significantly increased for PTH(1-84) by week 24 compared with SR (p < 0.0001). Significant changes from baseline in P1NP and BSAP were noted for PTH(1-84) from week 4 onwards; no significant changes were noted for SR. A trend towards a positive impact on QoL was seen with PTH(1-84) treatment. Safety profiles concur with previous analyses. CONCLUSIONS: PTH(1-84) had a more rapid and higher effect on bone formation markers compared to SR, indicating that SR has a different mode of action on bone remodeling than the bone building agent PTH(1-84) in postmenopausal women with osteoporosis.

Complaints of stress in young soldiers strongly predispose to psychiatric morbidity and mortality: Danish national cohort study with 10-year follow-up.

OBJECTIVE: Serving military can be regarded as exposure to a moderate enforced stressor independent of other vulnerability factors. The aims of this study were i) to explore psychiatric morbidity and mortality during 10 years of follow-up in a cohort of healthy adolescent Danish conscripts and ii) to investigate whether stress-related disorders precede other psychiatric disorders. METHOD: Controlled national cohort study on all psychiatric hospital contacts in young men referred to the Military Psychiatric Department (MPD) with 10 years of follow-up. RESULTS: During the follow-up period, 24% of conscripts seen at the MPD were diagnosed with a psychiatric disorder compared with 4% in the control cohort. Almost all diagnostic categories were over-represented but especially psychotic disorders. Mortality was substantially increased. Of subjects initially diagnosed with stress-related disorders at the MPD, 20% later on developed psychopathology. CONCLUSION: Young healthy men complaining of mental distress following a stressor are strongly disposed to psychiatric morbidity and mortality. The study suggests that stress-related disorders often precede more severe psychopathology.

Fetal programming: causes and consequences as revealed by studies of dietary manipulation in rats -- a review.

During pregnancy, the developing fetus is dependent on its mother for all nutritional requirements. It is not surprising, therefore, that variations in maternal nutrition can be reflected in alterations in fetal health and well-being. Interestingly, the changes can persist into adulthood and may result in increased risk of diseases such as diabetes, obesity and cardiovascular disease. The first observations of these phenomena resulted in the development of hypotheses collectively brought under the heading of "fetal" or, more recently, "developmental" programming. In this review, we will examine some of the animal models used to understand the mechanisms involved and attempt to determine whether there are common, "gatekeeper", pathways or genes, altered by the different nutritional stresses. We will concentrate primarily on nutrition related to post-natal development of hypertension and will restrict the review to studies in rodents, since that is where most of the mechanistic studies are being undertaken. Our conclusions are that, while there may well be some common gatekeeper pathways, there is also some diversity of mechanism which may contribute to the generation of the same or similar phenotypes.

Mechanism of protein tyrosine phosphatase 1B-mediated inhibition of leptin signalling.

Upon leptin binding, the leptin receptor is activated, leading to stimulation of the JAK/STAT signal transduction cascade. The transient character of the tyrosine phosphorylation of JAK2 and STAT3 suggests the involvement of protein tyrosine phosphatases (PTPs) as negative regulators of this signalling pathway. Specifically, recent evidence has suggested that PTP1B might be a key regulator of leptin signalling, based on the resistance to diet-induced obesity and increased leptin signalling observed in PTP1B-deficient mice. The present study was undertaken to investigate the mechanism by which PTP1B mediates the cessation of the leptin signal transduction. Leptin-induced activation of a STAT3 responsive reporter was dose-dependently inhibited by co-transfection with PTP1B. No inhibition was observed when a catalytically inactive mutant of PTP1B was used or when other PTPs were co-transfected. PTP1B was able to dephosphorylate activated JAK2 and STAT3 in vitro, whereas either no or a minimal effect was observed with cluster of differentiation 45 (CD45), PTPalpha and leukocyte antigen-related (LAR). By utilisation of a selective PTP1B inhibitor, the leptin-induced STAT3 activation was enhanced in cells. In conclusion, these results suggested that the negative regulatory role of PTP1B on leptin signalling is mediated through a direct and selective dephosphorylation of the two signalling molecules, JAK2 and STAT3.

Altered modulation of prefrontal and subcortical brain activity in newly diagnosed schizophrenia and schizophreniform disorder. A regional cerebral blood flow study.

To measure prefrontal and subcortical activity during a cognitive task, we examined 19 newly diagnosed schizophrenics and patients with schizophreniform psychosis. Seven healthy volunteers served as controls. The patients were drug naive or had received neuroleptics for a few days only. Cerebral blood flow distribution was depicted by single photon emission computed tomography at rest and during activation with the Wisconsin Card Sorting Test. A significant relative activation deficit in the left inferior-prefrontal region was revealed during the Wisconsin Card Sorting Test in the patient group. Furthermore, the patients had impaired striatal suppression on the left side during the cognitive task. The test performance was significantly impaired in the patients. The inability to reduce striatal activity may be due to a lack of corticostriatal feedback during prefrontal activation.

In vivo mitral valve morphology and motion in mitral valve prolapse.

Mitral leaflet morphology in mitral valve prolapse (MVP) has been suggested to be prognostically important, but in vivo valvular morphology is incompletely described in patients with MVP or in normal subjects. Accordingly, the length of both mitral leaflets and their zone of apposition, the thickness of their rough and clear zones, diastolic and systolic mitral annular diameters, and indexes of abnormal leaflet motion were measured in the parasternal long-axis echocardiographic view in 100 patients with MVP and 100 age- and sex-matched normal subjects. In both groups posterior leaflet thickness was related to age, as were anterior leaflet thickness and posterior leaflet length in patients with MVP. Compared with normal subjects, MVP patients without mitral regurgitation had thickened leaflets, elongated anterior leaflets, and large annular diameters (p < 0.0001). Patients with severe regurgitation had thicker leaflets, longer posterior leaflet and annular dimensions, and more abnormal leaflet motion than MVP patients without regurgitation. Leaflet thicknesses of different zones were supranormal in 60% to 67% and in 49% to 59% of MVP patients with and without severe regurgitation, respectively. MVP patients with regurgitation also had higher prevalences of abnormal mitral annular diameter than those without regurgitation (67% vs 29%) and > 3 mm posterior leaflet billowing into the left atrium (60% vs 34%). Thus, mitral valve size and leaflet thickness are increased in MVP patients without as well as with clinically important mitral regurgitation. The usefulness of leaflet thickening as a marker of severe MVP is limited by its high prevalence in patients with clinically mild MVP.

Regional cerebral blood flow distribution in newly diagnosed schizophrenia and schizophreniform disorder.

Regional cerebral blood flow distribution (rCBF) in 24 first admissions with schizophrenia or schizophreniform disorder and in 17 healthy volunteers was examined. Single photon emission computed tomography with a brain-retained tracer, technetium-99m-d,l-hexamethyl-propylene amine oxime, was used to study subjects under resting conditions and during performance of the Wisconsin Card Sorting Test. The study is a replication of a previous investigation in an independent series of patients and healthy volunteers. The patients had significantly lower relative blood flow in prefrontal regions during activation than did the healthy volunteers. An earlier series of 19 patients and 7 healthy volunteers was studied using exactly the same procedure. Analyses of the combined samples from the two studies (43 patients and 24 healthy volunteers) showed the patients to have significantly lower relative flow in prefrontal regions both at rest and during activation and higher flow in the left striatum during activation. The same finding emerged when analyses were confined to drug-naive patients and patients educationally matched to the healthy volunteers. The study suggests a defective frontostriatal interrelationship in schizophrenia and schizophreniform disorder.

Analysis of scenarios for sewerage, wastewater treatment and prioritised load on environment from the Greater City of Copenhagen.

The sewer system for the Greater Copenhagen area covers an area of 4460 ha contributing to the runoff. The total area serves in total 8 municipalities, however it is dominated by the areas in the City of Copenhagen proper. The catchments merge into interceptors, which feed two large treatment plants. The effluent from the two treatment plants discharges during dry weather to Oresund, the sound between Denmark and Sweden. This large system has been analysed for selected scenarios with respect to handling runoff in an optimal way in order to minimise the loads on the most sensitive receiving waters and optimising treatment plant performance.

These include biological, psychodynamic and social psychological theories. Experimental variables related to the subject, the investigator and the design of the research are presented. A review of the clinical and practical implications of sensory deprivation is given. It is emphasized that sensory deprivation might contribute to development of symptomatology in numerous situations. Finally, the potential therapeutic effects of controlled sensory deprivation are discussed.

[The epidemiology of post-traumatic stress disorders]. / Posttraumatiske psykiske forstyrrelsers epidemiologi.

Post-traumatic stress disorder (PTSD) has been subjected to several epidemiological studies during the last 10 years. Large differences in prevalence between different studies can only partly be explained by differences in methodology, impact of the trauma and populations. Changes in diagnostic criteria, the stressor criteria, general mentality over time and cultural differences may account for some of the differences. In general populations a lifetime prevalence of PTSD of between 1% and 9% has been found. In unselected traumatized populations 20-45% will develop PTSD after exposure to significant traumas. Among soldiers who have participated in battles of war a PTSD prevalence of 15-20% has been found. After exposure to lesser traumas and among well-trained corps 5-10% develop PTSD. Over long periods the point prevalence of PTSD in a given traumatized population diminishes. Predictive factors related to PTSD are complex.

[Posttraumatic stress disorder. 2. Therapy and clinical examples]. / Posttraumatic stress disorder. 2. Terapi og kliniske eksempler.

The principles of short-term psychotherapy for the posttraumatic stress disorder are summarized. A review is presented of psychopharmacological treatment of the posttraumatic stress disorder (PTSD). The case histories of three patients with PTSD are briefly mentioned.

[Posttraumatic stress disorder. 1. Background]. / Posttraumatic stress disorder. 1. Baggrund.

This article gives a review of the theoretical and clinical conditions in the posttraumatic stress disorder (PTSD), a diagnosis which was introduced in 1980. Investigations suggest a definite relationship between the traumata and the subsequent stress disturbances while the roles played by premorbid factors and the paratraumatic happenings are still not elucidated. The conditions is common after violent traumata. The subsequent course tends to be chronic although the prognosis in many cases in which rapid intervention is instituted is good. Greater awareness of the occurrence of PTSD is recommended.

[Heroin abuse among Danish prisoners on remand. I. Prevalence related to form of administration]. / Heroinmisbrug blandt danske varetaegtsarrestanter. I. Proevalens relateret til administrationsform.

Two groups of Danish prisoners on remand (in solitary confinement and not in solitary confinement) were examined by interview on reception (n = 133 & n = 95) in order to evaluate the prevalence and form of administration of opioid abuse/dependence. About 50% had abused opioids during their lifetime; one third were dependent at the time of reception. Twenty percent of opioid dependent prisoners administered opioids by smoking. More intravenous users were treated with methadone before and during imprisonment than those who were dependent on smoking opioids. Few were objectively suffering from withdrawal symptoms. The psycho-social impact of dependence on smoking heroin and intravenous heroin one month prior to imprisonment was at the same level and substantial as measured by the Global Assessment Scale.

[Heroin abuse among Danish prisoners on remand. II. Consequences related to form of administration]. / Heroinmisbrug blandt danske varetaegtsarrestanter. II. Konsekvenser of afhaengighed relateret til administrationsform.

Heroin-abusing Danish prisoners remanded in custody were based on interviews grouped as either smoking dependent (n = 18) or intravenous dependent (n = 55). Intravenous users had a longer duration and earlier debut of abuse than users who smoked opiates. Only intravenous users had serious somatic complications. Both groups of opioid dependent prisoners were marked by severe psychosocial dysfunction and considerable psychiatric co-morbidity. The intravenous users were generally more affected than the smokers concerning social and psychiatric parameters and earlier criminality, perhaps due to their longer duration of abuse.

[Abnormal neurological findings at first admission in patients with schizophrenia or schizophreniform disorders. Results of computer tomography and measurement of regional cerebral blood flow]. / Neurologiske abnormfund hos førstegangsindlagte patienter med skizofreni eller skizofreniform forstyrrelse. Sammenhoeng med resultater af computertomografi og måling af regional cerebral blodgennemstrømning.

Forty-five patients with schizophrenia or schizophreniform disorder admitted to hospital for the first time had a neurological examination, including integrative sensory and complex motor acts, by a trained neurologist. The patients were studied by CT and regional cerebral blood flow as well. A control group of 24 healthy volunteers was included. The patients had significantly more neurological abnormalities (NA) than the healthy volunteers. Medication did not explain the discrepancy. The NA were associated with sulcal enlargement and smaller brains as visualized by CT but not with ventricular enlargement. There was no association between the regional flow values and NA.
