Abstract
BACKGROUND Alzheimer's disease (AD) is a continuum of events beginning with an increase in brain soluble Aβ42 followed by the appearance of hyperphosphorylated tau (P-tau, asymptomatic stage). Mild Cognitive Impairment (MCI) then appears (prodromal stage). However, the individual contribution of these two soluble proteins in the onset of the first cognitive symptoms remains unclear. OBJECTIVES We sought to understand the specific impact of p-tau on the development of MCI in the AAV-AD rat model, a model of late-onset Alzheimer's disease (LOAD) predementia. METHODS We specifically reduced the phosphorylation level of tau while leaving Aβ42 levels unchanged using a DYRK1A protein kinase inhibitor, Leucettine L41, in an adeno-associated virus-based Alzheimer's disease (AAV-AD) rat model. Leucettine L41 was administered by intraperitoneal injection at 20 mg/kg per day in AAV-AD rats from 9 (late asymptomatic phase) to 10 (prodromal phase) months of age. RESULTS Decreased soluble forms of P-tau induced by chronic administration of Leucettine L41 did not change soluble Aβ42 levels but prevented MCI onset in 10-month-old AAV-AD rats. CONCLUSIONS The present study argues that P-tau is required to induce the development of MCI. Consistent with our previous findings that soluble Aβ42 is also required for MCI onset, the data obtained in the AAV-AD rat model confirm that the transition from the asymptomatic to the prodromal stage may be caused by the combined presence of both soluble brain forms of Aβ42 and p-tau, suggesting that the development of MCI may be the consequence of their synergistic action.

Management of anticoagulation in pregnant women with venous thromboembolism: An international survey of clinical practice. Thromb Res 2021; 210:20-25. [PMID: 34968851 DOI: 10.1016/j.thromres.2021.12.016] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/27/2021] [Revised: 11/25/2021] [Accepted: 12/16/2021] [Indexed: 11/16/2022]
Abstract
INTRODUCTION Venous thromboembolism (VTE) is an important cause of maternal morbidity and mortality. During pregnancy, VTE is treated with low-molecular-weight-heparin (LMWH). Studies assessing the optimal duration and peripartum management of therapeutic anticoagulation are lacking. This survey aimed to assess clinician practices for the management of anticoagulation in pregnant women with acute VTE. METHODS An electronic survey consisting of clinical scenarios addressing anticoagulation management for VTE in pregnancy was created. The target sample was clinicians likely to be involved in the management of pregnant women with acute VTE. The survey completion rate and proportion of individuals selecting a response were determined. RESULTS 96 respondents completed the survey including general internists (56.3%), hematologists (21.9%), and obstetricians (6.3%). In the management of a VTE in first or second trimester, most respondents preferred therapeutic LMWH until 6 weeks postpartum. In the first and second trimester, 48.0% and 37.5% of respondents, respectively, opted to reduce the dose of anticoagulation after 3 or 6 months. 29.2% of physicians opted for bridging with intravenous heparin around delivery when treating a VTE in the third trimester. 73.0% perceived an increased risk of clinically relevant non-major bleeding associated with the use of therapeutic anticoagulation in the peripartum and postpartum periods. CONCLUSIONS The survey highlights a wide variability of practice in the management of therapeutic anticoagulation in pregnancy. Larger scale studies with relevant clinical outcomes including thrombosis and bleeding risks are needed to inform clinical practice.

Abstract
OBJECTIVE To examine the association between pre-eclampsia definition and pregnancy outcome. DESIGN Secondary analysis of Control of Hypertension in Pregnancy Study (CHIPS) trial data. SETTING International multicentre randomised controlled trial (RCT). POPULATION In all, 987 women with non-severe non-proteinuric pregnancy hypertension. METHODS We evaluated the association between pre-eclampsia definitions and adverse pregnancy outcomes, stratified by hypertension type and blood pressure control. MAIN OUTCOME MEASURES Main CHIPS trial outcomes: primary (perinatal loss or high-level neonatal care for >48 hours), secondary (serious maternal complications), birthweight <10th centile, severe maternal hypertension, delivery at <34 or <37 weeks, and maternal hospitalisation before birth. RESULTS Of 979/987 women with informative data, 280 (28.6%) progressed to pre-eclampsia defined restrictively by new proteinuria, and 471 (48.1%) to pre-eclampsia defined broadly as proteinuria or one/more maternal symptoms, signs or abnormal laboratory tests. The broad (versus restrictive) definition had significantly higher sensitivities (range 62-79% versus 36-50%), lower specificities (range 53-65% versus 72-82%), and similar or higher diagnostic odds ratios and 'true-positive' to 'false-positive' ratios. Stratified analyses showed similar results. Addition of available fetoplacental manifestations (stillbirth or birthweight <10th centile) to the broad pre-eclampsia definition improved sensitivity (74-87%). CONCLUSIONS A broad (versus restrictive) pre-eclampsia definition better identifies women who develop adverse pregnancy outcomes. These findings should be replicated in a prospective study within routine healthcare to ensure that the anticipated increase in surveillance and intervention in a larger number of women with pre-eclampsia is associated with improved outcomes, reasonable costs and congruence with women's values. TWEETABLE ABSTRACT A broad (versus restrictive) pre-eclampsia definition better identifies the risk of adverse pregnancy outcomes.

Abstract
BACKGROUND The Resilience Against Depression Disparities (RADD), a community partnered, randomized comparative effectiveness study, aimed to address mental health in Lesbian, Gay, Bisexual, Transgender, and Queer/Questioning (LGBTQ) racial/ethnic populations in New Orleans and Los Angeles. OBJECTIVES To describe engagement methods, lessons learned, and recommendations in engaging LGBTQ individuals and agencies throughout the RADD study. METHODS RADD used a community partnered participatory research framework to engage LGBTQ community members and agencies. Observational and quantitative data were collected to describe engagement activities and study adaptations from October 2016 to May 2019. RESULTS Our partnered approach resulted in multiple study adaptations. The principles of cultural humility, coleadership, and addressing health determinants were important to successful engagement with LGBTQ community members and study participants. We recommend maintaining cultural humility as the tenant of all research activities. CONCLUSIONS This project's engagement plan demonstrates that community-academic partnerships can be forged to create and modify existing study models for LGBTQ communities.

Abstract
INTRODUCTION Depression is the leading cause of adult disability and common among sexual and gender minority (SGM) adults. The current study builds on findings showing the effectiveness of depression quality improvement (QI) and delivery of cognitive behavioural therapy (CBT) skills provided by community health workers in reducing depression. Depression QI approaches across healthcare and social/community services in safety-net settings have shown improvements in mental wellness, mental health quality of life and depression over 12 months. Further, a randomised study showed improved depression among low-income racial/ethnic minorities enrolled in a CBT-informed resiliency class (Building Resilience and Increasing Community Hope (B-RICH)). The current protocol describes a comparativeness effectiveness study to evaluate whether predominantly low-income, SGM racial/ethnic minority adults randomised to a CBT-informed resiliency class have improvements in depressive symptoms over and above community-engaged QI resources and training only. METHODS AND ANALYSIS The study approached three clusters of four to five programs serving predominantly SGM and racial/ethnic minority communities in the USA: two clusters in Los Angeles, California, and one in New Orleans, Louisiana. Clusters are comprised of one primary care, one mental health and two to three community agencies (eg, faith-based, social services/support, advocacy). All programs received depression QI training. The current study employed a community-partnered participatory research model to adapt the CBT-informed resiliency class, B-RICH+, to SGM communities. Study participants were screened and recruited in person from participating programs, and will complete baseline, 6- and 12-month survey follow-ups. Participants were depressed adults (8-item Patient Health Questionnaire ≥10; ≥18 years of age) who provided contact information. Enrolled participants were individually randomised to B-RICH+ or depression QI alone. Primary outcomes are depressive symptoms; secondary outcomes are mental health quality of life, mental wellness and physical health quality of life. Data collection for this study is ongoing. ETHICS AND DISSEMINATION The current study was approved by the UCLA Institutional Review Board. Study findings will be disseminated through scientific publications and community conferences.

Abstract
BACKGROUND Beer has been related to gastroesophageal reflux (GER) and dyspepsia, based on its alcohol and gas content. The aim of this study is to evaluate the association between moderate consumption of traditional and alcohol-free beer and upper digestive symptoms, gastric accommodation and GER. METHODS Healthy adults without frequent gastrointestinal symptoms and GER disease were included. The intervention involved administration of traditional beer to 10 subjects (substudy 1) and alcohol-free beer to 20 (substudy 2); control intervention entailed administration of water. Study duration was 2 weeks (control/intervention). Postprandial gastric accommodation was assessed through the maximum tolerated volume during a nutrient drink test after the ingestion of water (day 1) and beer (day 8), in which symptoms of dyspepsia were evaluated every 5 minutes. An impedance-pH monitoring assessed 24 hours and post-NDT GER (days 1 and 8). Symptoms were evaluated daily during the study. The defined variables were compared between visits and weeks using a nonparametric test for paired data. KEY RESULTS Dyspepsia symptoms showed a progressive increase during the NDT for both interventions in the 2 substudies, though no significant differences were detected in the MTV analysis. No differences were detected in the sum of weekly symptoms. The analysis of impedance-pH monitoring did not show any differences between intervention and control visits for both interventions. CONCLUSIONS AND INFERENCES Moderate consumption of traditional and alcohol-free beer does not increase dyspeptic symptoms or GER in healthy subjects, whether in a controlled-intake or real-life situation. Neither gastric accommodation nor reflux episodes are modified in this context.

Abstract
In this Clinical practice guide we examine the diagnostic and therapeutic management of adult patients with constipation and abdominal discomfort, at the confluence of the spectrum of irritable bowel syndrome and functional constipation. Both fall within the framework of functional intestinal disorders and have major personal, health and social impact, altering the quality of life of the patients affected. The former is a subtype of irritable bowel syndrome in which constipation and altered bowel habit predominate, often along with recurring abdominal pain, bloating and abdominal distension. Constipation is characterised by infrequent or hard-to-pass bowel movements, often accompanied by straining during defecation or the sensation of incomplete evacuation. There is no underlying organic cause in the majority of cases; it being considered a functional bowel disorder. There are many clinical and pathophysiological similarities between the two conditions, the constipation responds in a similar way to commonly used drugs, the fundamental difference being the presence or absence of pain, but not in an "all or nothing" way. The severity of these disorders depends not only on the intensity of the intestinal symptoms but also on other biopsychosocial factors: association of gastrointestinal and extraintestinal symptoms, degree of involvement, forms of perception and behaviour. Functional bowel disorders are diagnosed using the Rome criteria. This Clinical practice guide adapts to the Rome IV criteria published at the end of May 2016. The first part (96, 97, 98) examined the conceptual and pathophysiological aspects, alarm criteria, diagnostic test and referral criteria between Primary Care and Gastroenterology. This second part reviews all the available treatment alternatives (exercise, fluid ingestion, diet with soluble fibre-rich foods, fibre supplements, other dietary components, osmotic or stimulating laxatives, probiotics, antibiotics, spasmolytics, peppermint essence, prucalopride, linaclotide, lubiprostone, biofeedback, antdepressants, psychological treatment, acupuncture, enemas, sacral root neurostimulation and surgery), and practical recommendations are made for each.

Abstract
BACKGROUND As treatments for constipation become increasingly available, it is important to know when to progress along the treatment algorithm if the patient is not better. AIM To establish the definition of failure of a treatment to provide adequate relief (F-PAR) to support this management and referral process in patients with chronic constipation. METHODS We conducted an international Delphi Survey among gastroenterologists and general practitioners with a special interest in chronic constipation. An initial questionnaire based on recognised rating scales was developed following a focus group. Data were collected from two subsequent rounds of questionnaires completed by all authors. Likert scales were used to establish a consensus on a shorter list of more severe symptoms. RESULTS The initial focus group yielded a first round questionnaire with 84 statements. There was good consensus on symptom severity and a clear severity response curve, allowing 67 of the symptom-severity pairings to be eliminated. Subsequently, a clear consensus was established on further reduction to eight symptom statements in the final definition, condensed by the steering committee into five diagnostic statements (after replicate statements had been removed). CONCLUSIONS We present an international consensus on chronic constipation, of five symptoms and their severities, any of which would be sufficient to provide clinical evidence of treatment failure. We also provide data representing an expert calibration of commonly used rating scales, thus allowing results of clinical trials expressed in terms of those scales to be converted into estimates of rates of provision of adequate relief.

Abstract
This study aimed to analyse the impact of high and low flexibility levels of hamstring and quadriceps muscles on physical fitness and neuromuscular properties in professional soccer players. 62 male professional soccer players participated in this study and performed 2 instrumented flexibility tests (passive straight leg raise [PSLR] and quadriceps flexibility [QF]). Anaerobic performance was assessed using countermovement jump (CMJ), Abalakov vertical jump, 20-m sprint, and Balsom agility test. A k-means cluster analysis was performed to identify a cut-off value of hamstring and quadriceps flexibility and classify players as high hamstring flexibility (HHF) and low hamstring flexibility (LHF) or high quadriceps flexibility (HQF) and low quadriceps flexibility (LQF), respectively, according to the PSLR and QF performances. The LQF players performed better than HQF on CMJ (p=0.042, ES: 0.64) and Balsom agility test (p=0.029, ES: 0.68). In addition, LQF showed higher muscular stiffness than HQF players (p=0.002, ES: 0.88). There were no significant differences between HHF and LHF groups. When pooling the HQF and LQF players' data, the Pearson's correlation showed significant moderate positive association between muscular stiffness and QF (r=0.516, p<0.001). These results support the rationale that baseline stiffness is likely to influence athletic performance rather than flexibility level in soccer players.

Abstract
OBJECTIVE To compare pregnancy outcomes, accounting for allocated group, between methyldopa-treated and labetalol-treated women in the CHIPS Trial (ISRCTN 71416914) of 'less tight' versus 'tight' control of pregnancy hypertension. DESIGN Secondary analysis of CHIPS Trial cohort. SETTING International randomised controlled trial (94 sites, 15 countries). POPULATION OR SAMPLE Of 987 CHIPS recruits, 481/566 (85.0%) women treated with antihypertensive therapy at randomisation. Of 981 (99.4%) women followed to delivery, 656/745 (88.1%) treated postrandomisation. METHODS Logistic regression to compare outcomes among women who took methyldopa or labetalol, adjusted for the influence of baseline factors. MAIN OUTCOME MEASURES CHIPS primary (perinatal loss or high level neonatal care for >48 hours) and secondary (serious maternal complications) outcomes, birthweight <10th centile, severe maternal hypertension, pre-eclampsia and delivery at <34 or <37 weeks. RESULTS Methyldopa and labetalol were used commonly at randomisation (243/987, 24.6% and 238/987, 24.6%, respectively) and post-randomisation (224/981, 22.8% and 433/981, 44.1%, respectively). Following adjusted analyses, methyldopa (versus labetalol) at randomisation was associated with fewer babies with birthweight <10th centile [adjusted odds ratio (aOR) 0.48; 95% CI 0.20-0.87]. Methyldopa (versus labetalol) postrandomisation was associated with fewer CHIPS primary outcomes (aOR 0.64; 95% CI 0.40-1.00), birthweight <10th centile (aOR 0.54; 95% CI 0.32-0.92), severe hypertension (aOR 0.51; 95% CI 0.31-0.83), pre-eclampsia (aOR 0.55; 95% CI 0.36-0.85), and delivery at <34 weeks (aOR 0.53; 95% CI 0.29-0.96) or <37 weeks (aOR 0.55; 95% CI 0.35-0.85). CONCLUSION These nonrandomised comparisons are subject to residual confounding, but women treated with methyldopa (versus labetalol), particularly those with pre-existing hypertension, may have had better outcomes. TWEETABLE ABSTRACT There was no evidence that women treated with methyldopa versus labetalol had worse outcomes.

Abstract
BACKGROUND Randomized trials have confirmed the efficacy of prucalopride for the treatment of chronic constipation up to 12 weeks. This study aimed to assess the efficacy of prucalopride over a 24-week period (ClinicalTrials.gov: NCT01424228). METHODS Adults with chronic constipation and ≤2 spontaneous complete bowel movements (SCBMs)/week were randomized to receive prucalopride 2 mg or placebo daily for 24 weeks. The primary endpoint was the proportion of patients achieving a mean of ≥3 SCBMs/week over the treatment period, assessed using daily e-diaries. Secondary outcomes and safety parameters were assessed throughout the study. KEY RESULTS Overall, 361 patients were randomized and received prucalopride or placebo. Baseline characteristics were similar in the prucalopride (N = 181) and placebo (N = 180) groups. Mean age was 48.9 years (standard deviation, 16.0) and most patients were women. The proportion of participants achieving the primary endpoint was not statistically different between the prucalopride and placebo groups (25.1% vs 20.7%; p = 0.367). There was also no statistically significant difference between groups over the first 12-week period (prucalopride, 25.1%; placebo, 20.1%; p = 0.341). There were no statistically significant differences between groups for most secondary endpoints. No new safety concerns were identified. CONCLUSIONS & INFERENCES This trial did not show statistically significant improvements in primary or secondary outcomes with prucalopride compared with placebo over 24 or 12 weeks. This is in contrast to the results of four previous 12-week trials, which demonstrated prucalopride to be significantly more effective than placebo. An extensive evaluation did not provide an explanation for the null efficacy results of this study.

Abstract
AIM We tested the hypothesis that diabetes in pregnancy may differentially affect neonatal outcomes in twin vs. singleton pregnancies. METHODS In a retrospective cohort analysis of twins (n = 422 068) and singletons (n = 14 298 367) born in the USA from 1998 to 2001, we evaluated the adjusted odds ratios of adverse neonatal outcomes comparing diabetic vs. non-diabetic pregnancies, controlling for maternal characteristics. Primary outcomes include macrosomia (birthweight for gestational age > 90th percentile), congenital anomalies, low 5-min Apgar score (< 4) and neonatal death. RESULTS Diabetes in pregnancy was associated with a similarly increased risk of congenital anomalies (adjusted odds ratios 1.52 vs. 1.59) and smaller increased risks of preterm birth (adjusted odds ratios 1.27 vs. 1.49) and macrosomia (adjusted odds ratios 1.38 vs. 2.03) in twins vs. singletons, but reduced risks of low 5-min Apgar score (adjusted odds ratio 0.74) and neonatal death (adjusted odds ratio 0.76) in twins but not singletons. CONCLUSIONS Diabetes in pregnancy may differentially affect neonatal outcomes in twins and singletons, indicating a need for further studies to differentiate the effects by clinical subtypes of diabetes in pregnancy, and to consider/evaluate differential clinical management protocols of diabetes in multiple vs. singleton pregnancies.

Abstract
The authors report a case of a neonate that was operated on with the diagnosis of right aortic arch and aberrant left subclavian artery and anomalous origin of right pulmonary artery from ascending aorta. Computed tomography (CT) scan suggested double aortic arch and cardiac catheterization suggested anomalous origin of right pulmonary artery from ascending aorta versus aorto-pulmonary window. The final diagnosis was made at the operation. There was a right aortic arch and aberrant left subclavian artery and persistent ductus arteriosus. Surgical repair consisted of section of the ductus arteriosus and reimplantation of the right pulmonary artery in the main pulmonary artery.

Abstract
BACKGROUND In spite of the widespread use of antihypertensives during pregnancy, data on their risks and benefits for the newborn are limited. We investigated the risk of major congenital malformations or small-for-gestational-age newborns (SGA) in relation to gestational use of antihypertensives. METHODS Within the Quebec Pregnancy Registry, we conducted two case-control studies. First, cases were defined as major congenital malformations diagnosed during the first year of life and controls were selected from the same cohort; index date was date of delivery. Gestational exposure was defined as filling a prescription for an antihypertensive during the 1st trimester of pregnancy. Next, cases (SGA) were defined as newborns with a birth weight <10th percentile for that gestational age and gender; controls were the newborns with a birth weight > or =10 percentile. Gestational exposure was defined as filling a prescription for an antihypertensive during the 2nd or 3rd trimester. Multivariate logistic regression models were used to estimate odds ratios (ORs) and 95% confidence intervals (95% CI). RESULTS We found that overall antihypertensives use during the 2nd or 3rd trimesters of pregnancy was associated with a higher risk of SGA (OR 1.53, 95% CI 1.17-1.99). Moreover, selective beta-blocker (OR 6.00, 95% CI 1.06-33.87), alpha beta blocker (OR 2.26, 95% CI 1.04-4.88), or centrally-acting adrenergic agents use (OR 1.70, 95% CI 1.00-2.89) was associated with a higher risk of SGA compared to non-use. CONCLUSION Gestational use of antihypertensives, especially beta-blocker, alpha beta blocker, or centrally-acting adrenergic agents, may increase the risk of SGA.

Abstract
BACKGROUND Rome III incorporates changes in the definition of functional gastrointestinal disorder that involve a 3-month recall time for symptoms, rather than 1-year. AIM To validate a new version of the Talley-Bowel Disease Questionnaire (Talley-BDQ) and assess the impact of recall time period on the prevalence of symptoms. METHODS A sample of community residents were randomly mailed a survey using 1-year (n = 396) or 3-month recall period (n = 374). We evaluated the reliability and the concurrent validity of the two versions of the questionnaire. The proportions of subjects reporting symptoms in the two versions were compared. RESULTS The median (IQR) kappa on symptom-related questions was 0.70 (0.57-0.76) from the 1-year version and 0.66 (0.56-0.77) from the 3-month version. A median kappa of 0.39 (0.19-0.70) and 0.58 (0.39-0.73) was observed for concurrent validation of the 1-year and 3-month versions respectively. Except for gastro-oesophageal reflux symptoms, no differences were observed on the prevalence of clinically relevant symptoms. CONCLUSION The revised Talley-BDQ is reliable, with excellent reproducibility and validity. There were few differences in reported symptom rates between the 3-month and 1-year recall time versions of the questionnaire. A 1-year recall time may more efficiently capture infrequent or subtle symptoms.

Abstract
BACKGROUND few studies have reported the onset and disappearance rates of gastroesophageal reflux symptoms (GERS) in the population. AIM to assess the occurrence and disappearance rates of GERS in Spain, and their impact on health-related quality of life (HRQL). PARTICIPANTS AND METHODS participants were selected at random from the general population of Madrid in age and sex strata. They were interviewed at home twice, 6 months apart. Heartburn, acid regurgitation and consultation were assessed with the gastroesophageal reflux questionnaire, and HRQL with the SF-36. RESULTS 709 individuals were included, and 451 (63.6%) were re-interviewed 6 months later. Among the 325 individuals without GERS, 9 developed weekly symptoms (2.2% [95% CI: 0.8, 3.4%]); 2 (22%) consulted because of GERS. Among the 34 subjects reporting weekly GERS initially, 26 did not report them at 6-months. Onset of GERS was associated with worsening scores in the physical summary of SF-36 (delta = -6.6 [95% CI: -11.8, -1.42]), while disappearance with an improved score (delta = -3.0 [95% CI: 0.0, 5.9]). CONCLUSION despite the lower prevalence of GERS in Spain, the occurrence rate is 2.2% in 6 months; however symptoms disappeared in more than half of subjects six months later. Developing GERS was associated with reduced HRQL, and their disappearance with improvement.

Abstract
The extent to which childhood asthma incidence is influenced by asthma control and severity during pregnancy is unknown. We have studied this association during the child's first 10 yrs of life. A two-stage, case-control study, nested in a cohort of 8,226 children of asthmatic mothers, was conducted using three interlinked databases of Quebec, Canada, and mailed questionnaires. A total of 2,681 asthmatic children and 30,318 age-matched controls were selected (< or =20 controls.case(-1); stage 1), and 3,254 selected mothers were mailed questionnaires to obtain additional information (stage 2). Asthma control and severity was defined using validated indexes and childhood asthma incidence based on at least one asthma-related diagnosis and prescription received within 2 yrs. A total of 44 confounders were considered. Compared with children of mild controlled asthmatic mothers, children whose mothers had moderate-to-severe uncontrolled asthma during pregnancy had an increased risk of asthma (adjusted OR 1.27, 95% CI 1.06-1.52). No increased risk was observed for children of mild uncontrolled and moderate-to-severe controlled mothers. Based on one of the largest studies of children of asthmatic mothers, a significant increase in asthma risk was demonstrated among children whose mothers had poor control and increased severity of asthma during pregnancy, indicating that this element should be added to the expanding list of determinants of childhood asthma. As it constitutes a risk factor where pregnant asthmatic females can intervene, it is of great importance for physicians to optimally treat asthmatic females during pregnancy and to encourage females to be adherent to the prescribed asthma medications.

Abstract
BACKGROUND The role of anticoagulants for the prevention of placental-mediated pregnancy complications is uncertain. OBJECTIVES Our aim was to investigate the effectiveness of dalteparin, a low-molecular-weight heparin, in preventing the recurrence of these complications in women without thrombophilia. PATIENTS/METHODS Between August 1 2000 and June 20 2007, 116 pregnant women with: (i) RESULTS Among the 110 women included in the final analysis, dalteparin was associated with a lower rate of the primary outcome [5.5% (n = 3/55) vs. 23.6% (n = 13/55), adjusted odds ratio (OR) 0.15, 95% confidence interval (CI) 0.03-0.70]. Secondary outcomes were not statistically different between the groups. Bleeding problems or thrombocytopenia did not occur. CONCLUSION In this pilot study, dalteparin is effective in decreasing the recurrence of placental-mediated complications in women without thrombophilia. Our results require confirmation in further randomized trials.

Abstract
BACKGROUND Thirteen studies investigating the association between asthma during pregnancy and perinatal mortality reported generally no increased risk. Most of these studies should be interpreted with caution because they were limited in terms of statistical power. A study was therefore undertaken to evaluate whether maternal asthma during pregnancy increases the risk of perinatal mortality. METHODS Through three administrative databases from Québec (Canada), a cohort of women with and without asthma who had at least one pregnancy between 1990 and 2002 was formed. Perinatal mortality was identified by diagnostic codes. The adjusted odds ratio (OR) of perinatal mortality in women with and without asthma was compared using Generalised Estimation Equation (GEE) models. The first model included all potential confounders (except small for gestational age, SGA), the second model excluded birth weight, gestational age at birth and SGA and the third model excluded birth weight, gestational age at birth but included only SGA. This analysis was also stratified for birth weight and gestational age at birth. RESULTS The cohort was formed of 13 100 and 28 042 single pregnancies in women with and without asthma. The crude OR of perinatal mortality was 1.35 (95% CI 1.08 to 1.67), which decreased to 0.93 (95% CI 0.75 to 1.17) after adjustment for birth weight and gestational age at birth. Women with asthma had a higher rate of low birthweight babies and preterm delivery than those without asthma. CONCLUSION The increased risk of low birthweight babies and premature delivery in women with asthma may partly explain the association between maternal asthma and the increased risk of perinatal mortality.

Abstract
Thirty-eight human immunodeficiency virus-1 (HIV-1)-infected pregnant women were administered tenofovir disoproxil fumarate (TDF; 300 mg)-emtricitabine (FTC; 200 mg) tablets: two at labor initiation and one daily for 7 days postpartum. Maternal, umbilical, and neonatal plasma tenofovir concentrations were measured by high-performance liquid chromatography and analyzed using a population approach. Data were described using a two-compartment model for the mother, an effect compartment linked to maternal circulation for cord, and a neonatal compartment disconnected after delivery. Absorption was greater for women delivering by caesarian section than for those delivering vaginally. The maternal 600 mg TDF administration before delivery produces the same concentrations as 300 mg administration in other adults. If the time elapsed between maternal administration and delivery is >or=12 h, two tablets of TDF-FTC should be readministered. Tenofovir showed good placental transfer (60%). Administering 13 mg/kg of TDF as soon as possible after birth should produce neonatal concentrations comparable with those observed in adults.

Abstract
BACKGROUND Several studies showed high prevalence of ineffective oesophageal motility (IOM) in gastro-oesophageal reflux disease (GERD) and suggested an important role for ineffective oesophageal motility in increased acid exposure. However, impedance-manometric studies proposed that only severe ineffective oesophageal motility might affect oesophageal clearance. OBJECTIVES (i) To re-assess the relevance of mild IOM in GERD and (ii) to test the reversibility of IOM. METHODS Oesophageal motility, clearance and acid exposure were assessed in 191 GERD patients: 99 without IOM; 58 with mild IOM (30-80% ineffective contractions) and 34 with severe IOM (>80% ineffective contractions). In 30 patients with oesophagitis, the potential reversibility of IOM was evaluated with edrophonium intravenously. RESULTS Patients with mild IOM had identical oesophageal clearance and acid exposure in comparison with those without IOM. Patients with severe IOM had a higher probability of prolonged supine clearance and acid exposure [odds ratio: 2.88 (1.16-7.17); 2.48 (0.99-6.17)]. This effect was independent of the presence of hiatal hernia and male sex. Severe IOM could be transiently reverted in 55% of patients. CONCLUSIONS Mild IOM does not affect oesophageal clearance. Only severe IOM is associated with prolonged clearance and acid exposure, particularly in supine periods. The edrophonium test might be useful to predict severe IOM response to prokinetic medications.

Abstract
OBJECTIVE To determine whether 'less tight' (versus 'tight') control of nonsevere hypertension results in a difference in diastolic blood pressure (dBP) between groups. DESIGN Randomised controlled trial (ISRCTN#57277508). SETTING Seventeen obstetric centres in Canada, Australia, New Zealand, and UK. POPULATION Inclusion: pregnant women, dBP 90-109 mmHg, pre-existing/gestational hypertension; live fetus(es); and 20-33(+6) weeks. Exclusion: systolic blood pressure > or = 170 mmHg and proteinuria, contraindication, or major fetal anomaly. METHODS Randomisation to less tight (target dBP, 100 mmHg) or tight (target dBP, 85 mmHg) blood pressure control. MAIN OUTCOME MEASURES Primary: mean dBP at 28, 32 and 36 weeks. Secondary: clinician compliance and women's satisfaction. Other: serious perinatal and maternal complications. RESULTS A total of 132 women were randomised to less tight (n = 66; seven had no study visit) or tight control (n= 66; one was lost to follow up; seven had no study visit). Mean dBP was significantly lower with tight control: -3.5 mmHg, 95% credible interval (-6.4, -0.6). Clinician compliance was 79% in both groups. Women were satisfied with their care. With less tight (versus tight) control, the rates of other treatments and outcomes were the following: post-randomisation antenatal antihypertensive medication use: 46 (69.7%) versus 58 (89.2%), severe hypertension: 38 (57.6%) versus 26 (40.0%), proteinuria: 16 (24.2%) versus 20 (30.8%), serious maternal complications: 3 (4.6%) versus 2 (3.1%), preterm birth: 24 (36.4%) versus 26 (40.0%), birthweight: 2675 +/- 858 versus 2501 +/- 855 g, neonatal intensive care unit (NICU) admission: 15 (22.7%) versus 22 (34.4%), and serious perinatal complications: 9 (13.6%) versus 14 (21.5%). CONCLUSION The CHIPS pilot trial confirms the feasibility and importance of a large definitive trial to determine the effects of less tight control on serious perinatal and maternal complications.

Abstract
OBJECTIVES The main objective of this study is to compare the rate of adherence to GTT done six weeks postpartum (early GTT) to the one performed three months or more after delivery (late GTT). The secondary objective is to determine factors associated to non-adherence to GTT. MATERIALS AND METHODS This is a retrospective study involving women with GDM who delivered in 1998 (late GTT; N=229) and 2003 (early GTT; N=244). We retrieved maternal, pregnancy, newborn and GDM parameters. Statistical analyses include the chi2 test and logistic regression analysis. RESULTS The rate of adherence to early GTT (77.1%) was statistically higher than the one observed for late GTT (45.6%; P<0.001). The factors identified as predictors of non-adherence were the year of delivery, parity > or = 2, problem of adherence to GDM treatment, and no breastfeeding six weeks after delivery. CONCLUSION GTT performed six weeks after delivery increases the adherence to the test. The factors associated with non-adherence are more related to personal matters than to GDM.

Abstract
INTRODUCTION lack of evidence in most clinical situations regarding irritable bowel syndrome (IBS) enhances the importance of an expert s opinion, which will guide management and even the concept underlying the disease. OBJECTIVE to delve into the knowledge and degree of agreement on main clinical skills for this syndrome among physicians involved in its management. MATERIAL AND METHOD two rounds of a Delphi survey were conducted on 100 physicians: general practitioners (GPs) and gastroenterologists. The questionnaire evaluated agreement among participants in some aspects regarding the definition, diagnosis, and treatment of IBS. RESULTS fifty-five percent of participants completed the two-round survey. Agreement was achieved regarding the definition of typical symptoms and red flags characterizing IBS. Although there was no consensus regarding the appropriate management of patients without alarm symptoms, the performance of a colonoscopy on any patient presenting red flags was suggested. Patients were thought to require a wider examination when older than 40. A well defined line of IBS treatment was not found, albeit most physicians tended to choose it depending on the main complaint. CONCLUSION interviewed physicians showed adequate theoretical knowledge of IBS, but lack of uniformity on diagnosis and treatment approach reflects the controversial day-by-day management of this syndrome.

Abstract
AIMS To develop a population pharmacokinetic model for stavudine in children and to investigate the consistency of the currently recommended dose based on adult target concentrations. METHODS The pharmacokinetics of stavudine were investigated using a population approach. Individual estimates of CL/F were used to calculate the stavudine dose required to achieve the area under the concentration-time curve reported in adults given recommended doses. RESULTS Stavudine pharmacokinetics were well described by a one-compartment model with zero-order absorption. Typical population estimates (% interindividual variability) of the apparent distribution volume (V/F) and plasma clearance (CL/F) were 40.9 l (32%) and 16.5 l h(-1) (38%), respectively. Stavudine V/F and CL/F were similarly related to age. Mean calculated doses (0.61 mg kg(-1) for children less than 2 weeks, 1.23 mg kg(-1) for children more than 2 weeks with bodyweight less than 30 kg, and 31.5 mg for children with a bodyweight between 30 and 60 kg) were in agreement with the current paediatric doses (0.5 mg kg(-1), 1 mg kg(-1), and 30 mg, respectively). CONCLUSIONS Our findings support the current recommended paediatric dosage regimens for stavudine, as they result in the same exposure to the drug as in adults.

Abstract
BACKGROUND We hypothesized that cancer-related inflammation might increase the risk of febrile neutropenia (FN) induced by docetaxel (DCX, Taxotere), by both affecting the exposure to DCX and the tissue sensitivity. PATIENTS AND METHODS Advanced cancer patients with normal liver function, performance status (PS)<3, were included. Cytochrome P450 3A (CYP 3A) activity was estimated before the first cycle of DCX by a single determination of midazolam plasma concentration, 4 hours after 0.015 mg/kg i.v. bolus. Following the first cycle of 75-100 mg/m2 DCX, clearance and area under the concentration versus time curve (AUC) were estimated using a limited sampling strategy. RESULTS Among 56 assessable patients, 7 FNs occurred after first cycle (13%). In univariate analysis, high midazolam concentration and free DCX AUC were associated with severe neutropenia and FN. In addition to DCX exposure-related parameters, the risk of FN was also correlated with poor PS, baseline lymphopenia and lung cancer, while high ferritin level, indicator of an inflammatory state, reached borderline significance (P=0.07). By multivariate analysis, total DCX AUC and baseline lymphopenia were associated with FN. High midazolam concentration was correlated with elevated ferritin level (r=0.32; P=0.02). CONCLUSION Inflammatory status and lymphocyte count should be included in the evaluation of the benefice/risk ratio before the initiation of DCX.

Abstract
BACKGROUND Overall success of prophylactic strategies against non-steroidal anti-inflammatory drug (NSAID) complications depends on the use of gastroprotective drugs. AIM We examined the use of antisecretory drugs in NSAID users in the general population of Spain. PARTICIPANTS AND METHODS In 2002, a phone interview was conducted with 2500 persons representative of the general population of Spain. Using a validated questionnaire, we asked about the use of NSAID, aspirin and antisecretory drugs, and history of digestive diseases. We estimated the use of antisecretory drugs in NSAID users, according to risk factors for gastrointestinal (GI) lesions associated with NSAID. RESULTS In total, 425 persons [17.0% (95% CI 15.5-18.5%)] were NSAID users. Of them, 69 persons (16.2%; 95% CI 12.7-19.7%) used antisecretory drugs [proton pump inhibitor (PPI) 11.8% and H2-blocker 4.9%]. Forty-four of the 224 NSAID users (19.6%) with one risk factor for GI lesions were antisecretory drug users (PPI 16%; H2-blocker 4%), compared with 24 of the 197 NSAID users (12.7%) without risk factors (PPI 6.6%; H2-blocker 6.1%). NSAID users with risk factors for GI lesions but without upper GI (UGI) symptoms did not consume more antisecretory drugs than equivalent non-NSAID users (12.9% vs. 10.7%). CONCLUSION Current strategies to prevent GI lesions in NSAID users are not effective from a population perspective, especially in subjects without UGI symptoms.

Abstract
OBJECTIVES To estimate the impact of gastroesophageal reflux (GER) symptoms on the utilization of healthcare services and work absenteeism in Spain. METHODS A cross-sectional study on 2,500 subjects representative of the Spanish population from 40 to 79 years of age. Data were collected via a telephone interview in January 2002 using Locke s questionnaire after its cross-cultural adaptation and validation for telephone use in Spain. RESULTS GER is responsible for 296.8 doctor consultations (95% CI: 245.3-348.7) per 1,000 inhabitants per year, for 24 esophagogastrointestinal radiographic studies per 1,000 inhabitants per year (95% CI: 18-30), for 32.4 (95% CI: 25.5-39.3) high digestive endoscopies per 1,000 inhabitants per year, and for the loss of 201 (95% CI: 0-411.1) working days per 1,000 employed inhabitants with GER per year. In relation to medication intake, GER resulted in 4,092 (95% CI: 3,300-5,133) treatment days with H2 antagonists per 1,000 inhabitants per year, 9,030 (95% CI: 7,846-10,332) treatment days with proton pump inhibitors per 1,000 inhabitants per year, and 1,082 (95% CI: 519-1,549) treatment days with prokinetics per 1,000 inhabitants per year. CONCLUSIONS GER has a large impact on the utilization of healthcare resources and work absenteeism in Spain, in contrast to the widespread belief that it is an illness of little importance.
