Purpose: In absence of comprehensive data collection on traumatic brain injury (TBI), the German Society for Neurosurgery (DGNC) and the German Society for Trauma Surgery (DGU) developed a TBI databank for German-speaking countries. Methods: From 2016 to 2020, the TBI databank DGNC/DGU was implemented as a module of the TraumaRegister (TR) DGU and tested in a 15-month pilot phase. Since its official launch in 2021, patients from the TR-DGU (intermediate or intensive care unit admission via shock room) with TBI (AIS head ≥ 1) can be enrolled. A data set of > 300 clinical, imaging, and laboratory variables, harmonized with other international TBI data collection structures is documented, and the treatment outcome is evaluated after 6- and 12 months. Results: For this analysis, 318 patients in the TBI databank could be included (median age 58 years; 71% men). Falls were the most common cause of injury (55%), and antithrombotic medication was frequent (28%). Severe or moderate TBI were only present in 55% of patients, while 45% suffered a mild injury. Nevertheless, intracranial pathologies were present in 95% of brain imaging with traumatic subarachnoid hemorrhages (76%) being the most common. Intracranial surgeries were performed in 42% of cases. In-hospital mortality after TBI was 21% and surviving patients could be discharged after a median hospital stay of 11 days. At the 6-and 12 months follow-up, a favorable outcome was achieved by 70% and 90% of the participating TBI patients, respectively. Compared to a European cohort of 2138 TBI patients treated in the ICU between 2014 and 2017, patients in the TBI databank were already older, frailer, fell more commonly at home. Conclusion: Within five years, the TBI databank DGNC/DGU of the TR-DGU could be established and is since then prospectively enrolling TBI patients in German-speaking countries. With its large and harmonized data set and a 12-month follow-up, the TBI databank is a unique project in Europe, already allowing comparisons to other data collection structures and indicating a demographic change towards older and frailer TBI patients in Germany.

Background and Purpose: The B-type natriuretic peptide (BNP1-32) exerts vasorelaxing and cardioprotective activity. BNP is used as a biomarker for the diagnosis of cardiopathological conditions and recombinant BNP1-32 as a drug for the treatment of such. BNP1-32 has a short half-life and thus, similar to other vasoactive peptides like angiotensin II and bradykinin, can be enzymatically truncated forming bioactive metabolites. We aimed to investigate the metabolism of BNP1-32 in the mouse lung, to identify potential new BNP metabolites and to disclose their biological activity compared to the BNP1-32, in vitro and in vivo.Experimental Approach: Using HPLC and MS, we identified a new BNP metabolite, BNP1-30, in the lung being generated by endothelin-converting enzyme-1.Key Results: BNP1-30 is more efficient in stimulating the guanylyl cyclase (GC) receptor A and, in contrast to BNP1-32, is also able to profoundly stimulate the GC-B. In vivo, BNP1-30 reduced the mean arterial BP of normotensive mice after acute infusion significantly more than BNP1-32. In a model of severe hypertension, a 3-day infusion of BNP1-30 was able to reduce systolic BP by 30 mmHg and to improve markers of heart failure, while BNP1-32 was without significant effect.Conclusions and Implications: Our results suggest that BNP1-32 is the precursor for the biologically more active BNP1-30 leading to a fundamental extension of the natriuretic peptide system. Due to expanded activity, BNP1-30 might be a promising treatment option for cardiovascular diseases. Furthermore, its potency as a new diagnostic marker of specific cardiac diseases should be evaluated. [ABSTRACT FROM AUTHOR]- Published

Background: Pancreatic cancer is a devastating disease with a dismal prognosis. Despite profound medical advances in systemic therapies for other types of aggressive tumours during recent years, a diagnosis of pancreatic cancer is still often synonymous with a fatal outcome. The term periampullary cancer includes pancreatic cancer and applies to the group of tumours found in proximity to the ampulla of Vater. Molecular events and immune response in the host during chemotherapy remain largely unexplored in this group of tumours. Therefore, the "Chemotherapy, Host Response and Molecular Dynamics in Periampullary Cancer (CHAMP)" study aims to monitor these processes to gain new insight into this perplexing disease.Methods: The CHAMP study is a prospective, single-arm observational study. All patients diagnosed with pancreatic or other periampullary adenocarcinoma undergoing adjuvant or palliative chemotherapy treatment in the Department of Oncology, Skåne University Hospital, are invited to participate. Clinical and pathological data will be compiled at study entry. A single tissue microarray (TMA) block is constructed for each patient with a resected tumour and blood samples are drawn before, during and after chemotherapy in order to sample peripheral blood mononuclear cells (PBMC), cytokines and circulating tumour DNA (ctDNA). Next generation sequencing will be performed on tumour tissue and ctDNA to detect changes in the clonal landscape over space and time.Discussion: Despite the recent emergence of some promising biomarkers for periampullary cancer, there has been a lack of success in clinical implementation. Cancer cells continuously adapt and become resistant to treatment during chemotherapy. To be able to keep pace with and hopefully overtake this rapid evolution we must, with the help of new diagnostic tools, be ready to adapt and alter treatment accordingly. It seems to us that the only way forward is to gain a better understanding of the dynamics of the disease during treatment. With insights gained from the CHAMP study we hope to find answers to key questions in this largely unexplored territory.Trial Registration: This study has been registered 30th October 2018 at clinicaltrials.gov as NCT03724994.

Background: Although many perinatal women are affected by anxiety, few studies have focused on perinatal anxiety and its potential triggers. The primary aim of this study was to examine concurrent and prospective associations between mid-pregnancy insomnia and perinatal anxiety. Furthermore, we compared psychosocial and reproductive characteristics between participants with and without mid-pregnancy insomnia and explored changes in the prevalence of obsessive-compulsive disorder (OCD) symptoms from mid-pregnancy to 8 weeks postpartum.Methods: This study was part of the Norwegian Depression and Anxiety in the Perinatal Period (DAPP) prospective, population-based, cohort study. We analyzed hospital birth records and questionnaire responses from pregnancy week 17 and postpartum week 8 (n = 530). The Bergen Insomnia Scale was used to measure insomnia and the Hopkins Symptom Checklist to measure anxiety. OCD symptoms were measured based on questions from the Mini-International Neuropsychiatric Interview.Results: Mid-pregnancy insomnia was significantly associated with both concurrent and postpartum anxiety in a linear mixed model adjusted for several potential confounders. Participants with mid-pregnancy insomnia had significantly higher levels of perinatal anxiety and postpartum OCD symptoms than participants with normal mid-pregnancy sleep. OCD symptoms affected more women after delivery than before (6.4% vs. 3.8% p = 0.034).Limitations: Immigrants were underrepresented in our sample.Conclusion: Our results suggest that mid-pregnancy insomnia is a marker for concurrent anxiety and predictor of postpartum anxiety. Future research should examine whether insomnia treatment starting in mid-pregnancy reduces both perinatal insomnia and anxiety. Health providers should also be aware that postpartum women have an increased risk of developing OCD symptoms. [ABSTRACT FROM AUTHOR]- Published

The purpose of this study was to translate, cross-culturally adapt, and assess the reliability and validity of the Pelvic Girdle Questionnaire (PGQ) in pregnant Nepalese women. The cross-cultural adaptation process was conducted according to the Guillemin guidelines. Reliability and validity were assessed using cross-sectional design. The participants responded to questionnaires of sociodemographics, the Nepali version of the PGQ, the Oswestry Disability Index, the Patient-Specific Functional Scale, the 5-item version of the Edinburgh Depression Scale, and the Numerical Pain Rating Scale. The internal consistency was assessed with Cronbach's alpha. The test–retest reliability was calculated using the intraclass correlation coefficient and smallest detectable change. Construct validity was assessed by testing 9 a priori hypotheses that examine correlations between the PGQ activity and symptom subscales, and also among the PGQ subscales and Oswestry Disability Index, Numerical Pain Rating Scale, Patient-Specific Functional Scale, and 5-item version of the Edinburgh Depression Scale. Spearman and Pearson's correlation were used to assess the correlations. A sample of 111 pregnant women were included in the study. The Cronbach's alpha for the Nepali version of the total PGQ was good (α = 0.83), and the test–retest reliability was acceptable (ICC 2.1 , 0.72) with a measurement error of SDC 95% 18.6 points. Seven of the 9 hypotheses found support, which confirms acceptable construct validity of the Nepali PGQ. The Nepali version of the PGQ is a reliable and valid tool for assessing pelvic girdle pain in pregnant Nepalese women. [ABSTRACT FROM AUTHOR]

Background: Life expectancy is reduced by 19 years in men and 17 in women with psychosis in Sweden, largely due to cardiovascular disease.Aim: Assess whether a psychosocial health promotion intervention improves cardiometabolic risk factors, quality of life, and severity of illness in patients with psychotic disorders more than treatment as usual.Methods: A pragmatic intervention trial testing a manual-based multi-component health promotion intervention targeting patients with psychosis. The Swedish intervention was adapted from IMPaCT therapy, a health-promotion program based on motivational interviewing and cognitive behavioral therapy, designed to be incorporated into routine care. The intervention group consisted of 119 patients and the control group of 570 patients from specialized psychosis departments. Outcome variables were assessed 6 months before intervention during the run-in period, again at the start of intervention, and 12 months after the intervention began. The control group received treatment as usual.Results: The intervention had no significant effect on any of the outcome variables. However, BMI, waist circumference, systolic BP, heart rate, HbA1c, general health, and Clinical Global Impressions Scale score improved significantly during the run-in period before the start of the active intervention (observer effect). The multi-component design meant that treatment effects could only be calculated for the intervention as a whole.Conclusion: The results of the intervention are similar to those of the U.K. IMPaCT study, in which the modular health-promotion intervention had little effect on cardiovascular risk indicators. However, in the current study, the run-in period had a positive effect on cardiometabolic risk factors. [ABSTRACT FROM AUTHOR]- Published

Background: The cholinergic system is considered to play a key role in the development of postoperative delirium (POD), which is a common complication after surgery.Objectives: To determine whether peri-operative acetylcholinesterase (AChE) and butyrylcholinesterase (BuChE) activities are associated with the development of POD in in-hospital surgical patients, and raise hypotheses on cholinergic regulatory mechanisms in POD.Design: A prospective multicentre observational study by the Peripheral Cholinesterase-activity on Neurocognitive Dysfunctions in Surgical Patients (CESARO) study group.Setting: Nine German hospitals.Patients: Patients of at least 18 years of age scheduled for inpatient elective surgery for a variety of surgical procedures. A total of 650 patients (mean age 61.5 years, 52.8% male) were included.Methods: Clinical variables, and peripheral AChE and BuChE activities, were assessed throughout the peri-operative period using bedside point-of-care measurements (one pre-operative and two postoperative measurements). POD screening was conducted postoperatively for at least 24 h and up to the third postoperative day using a validated screening tool (nursing delirium screening scale).Results: In all, 179 patients (27.5%) developed POD within the early postoperative phase. There was a lower BuChE activity in patients with delirium compared with patients without delirium pre-operatively (Cohen's r = 0.07, P = 0.091), on postoperative day 1 (Cohen's r = 0.12, P = 0.003) and on postoperative day 2 (Cohen's r = 0.12, P = 0.002). In contrast, there was a significantly higher AChE activity in patients with delirium compared with patients without delirium pre-operatively (Cohen's r = 0.10, P = 0.012), on postoperative day 1 (Cohen's r = 0.11, P = 0.004) and on postoperative day 2 (Cohen's r = 0.13, P = 0.002). After adjusting for covariates in multiple logistic regression, a significant association between both BuChE and AChE activities and POD was not found. However, in the multivariable analysis using the Generalized Estimating Equation, cholinesterase activities showed that a decrease of BuChE activity by 100 U L increased the risk of a delirium by approximately 2.1% (95% CI 1.6 to 2.8%) and for each 1 U g of haemoglobin increase in AChE activity, there was a 1.4% (95% CI 0.6 to 2.2%) increased risk of POD.Conclusion: Peri-operative peripheral cholinesterase activities may be related to the development of POD, but the clinical implications remain unclear. Further studies, in homogeneous patient groups with a strict protocol for measurement time points, are needed to investigate the relationship between cholinesterase activities and POD.Trial Registration: www.clinicaltrials.gov.

Purpose: The objective of this study was to describe the outcome and prognostic factors for adults treated for localized myxofibrosarcoma.Methods and Materials: We conducted a retrospective multicenter study of 425 nonmetastatic patients who underwent surgery between January 1996 and December 2015 in French National Group and were enrolled in the Conticabase. Pathologic diagnosis was systematically reviewed by expert pathologists. The endpoints were relapse-free and metastasis-free survival. Log-rank tests and Cox models have been used to identified prognostic factors.Results: Median age was 66 years; 53% were males; 85% of cases occurred in limbs or superficial trunk; median size was 60 mm; 47% and 39% were grades 2 and 3, respectively; 66% had R0 resection and 34% R1 resection. Adjuvant radiation therapy was given to 65% of patients, neoadjuvant radiation therapy to 3%, neoadjuvant chemotherapy to 7%, and adjuvant chemotherapy to 13%. The median follow-up was 51 months. The 5-year local relapse-free survival was 67%; independent prognostic factors for local relapse were R1 resection (hazard ratio [HR] = 1.26; P = .001) and adjuvant radiation therapy (HR = 0.35; P = .0001) (ie, R1 resection and no adjuvant radiation therapy increase the hazard ratio). In stratified analysis, adjuvant radiation therapy was beneficial after R0 resection (P = .0020) and after R1 resection (P = .0001). The 5-year overall survival was 80%. The 5-year metastasis-free survival was 83%. Independent prognostic factors for metastatic relapse were grade 3 disease (HR = 1.975; P = .0001) and tumor size (HR = 1.006; P = .001).Conclusions: This large series of myxofibrosarcoma confirms the high rate of local relapse. Combination of R0 resection and adjuvant radiation therapy provided the best local control. In parallel with an increasing rate of R0 resection and adjuvant radiation therapy, we observed a constant improvement in both metastatic and local relapse-free survival during the study.

Abstract: Background: Oral health is an important predictor for general health, and poor oral health is interrelated with the manifestations of systemic disease. Aim: To determine the extent of oral health education in medical schools across Australia. Methods: A survey of Australian medical schools was conducted (September 2013 to June 2014). Participants were administrators and curricula coordinators of medical programmes. The main outcome measures were teaching hours of specific areas of oral health education. Data were descriptively analysed. Results: Participants from 8 of 18 universities responded to the questionnaire. The total hours dedicated to oral health in the medical programmes were: zero in one school; less than 2 h in three schools, 6–10 h in three schools and 30 h in one school. Only four schools taught the correlation between oral health and overall health, two schools taught about dental diseases (caries and periodontal disease), three schools taught dental trauma management and six schools taught oral anatomy. Only five schools taught about oral cancer: two of these taught about cancer for 10–15 min. No school reported hands‐on training in an oral health setting. Conclusions: The results indicate that Australian medical school graduates have little, if any, foundational knowledge of oral health (dental caries, bidirectional relationship between diabetes and periodontal disease, oral cancer and dental emergencies). The recognition of poor oral health plays a significant part in the early detection and care of chronic diseases. The teaching of fundamental oral health to medical students is crucial and should be integrated into medical school curricula. [ABSTRACT FROM AUTHOR]

Study Question: Is fatigue a frequent symptom of endometriosis?Summary Answer: Fatigue is an underestimated symptom of endometriosis as it affects the majority of women with endometriosis, but it is not widely discussed in literature.What Is Known Already: Fatigue can be a symptom of endometriosis causing major distress impacting the daily activities and quality of life of women with endometriosis. However, few studies with large sample sizes have investigated fatigue as a symptom of endometriosis.Study Design, Size, Duration: The study was designed as a multi-center matched case-control study. Recruitment took place at hospitals and private practices in Switzerland, Germany and Austria between 2010 and 2016. Data was collected from 1120 women, 560 of them with endometriosis. The women with endometriosis were matched to 560 control women in regard to age ±3 years and ethnic background.Participants/materials, Setting, Methods: Diagnosis of women with endometriosis had to be surgically and histologically confirmed. Surgical exclusion or absence of any endometriosis-identifying symptoms was required for control subjects. Materials included surgical and histological reports as well as data retrieved from a self-administered questionnaire. This study focused on the symptom fatigue in endometriosis. Relationships of variables were established by regression analysis and associations were quantified as odds ratios.Main Results and the Role Of Chance: Frequent fatigue was experienced by a majority of women diagnosed with endometriosis (50.7% versus 22.4% in control women, P < 0.001). Fatigue in endometriosis was associated with insomnia (OR: 7.31, CI: 4.62-11.56, P < 0.001), depression (OR: 4.45, CI: 2.76-7.19, P < 0.001), pain (OR: 2.22, CI: 1.52-3.23, P < 0.001), and occupational stress (OR: 1.45, CI: 1.02-2.07, P = 0.037), but was independent of age, time since first diagnosis and stage of the disease.Limitations, Reasons For Caution: Women with asymptomatic endometriosis cannot be excluded in the control group which would lead to underestimation of our results. The study's design allows no evaluation of causal effects.Wider Implications Of the Findings: As fatigue is experienced by numerous women with endometriosis, it needs to be addressed in the discussion of management and treatment of the disease. In addition to treating endometriosis, it would be beneficial to reduce insomnia, depression, pain and occupational stress in order to better manage fatigue.Study Funding/competing Interest(s): There was no additional funding received for this study and no conflict of interest.Trial Registration Number: ClinicalTrials.gov, NCT02511626.

Twenty years ago the 1st International Congress of Andrology took place in Barcelona. Since then these Congresses have become regular events and the meetings in Tel Aviv (1981) Boston (1985) Firenze (1989) Tokio (1993) and now in Salzburg bear witness to the steady growth of andrology as a scientific and clinical discipline. As Salzburg is the last International Congress of Andrology in this Century it may be timely to review the situation of andrology at the end of the 20th Century. Andrology can trace its scientific roots back to Antony van Leeuwenhoek (1632-1723) who in 1677 was the first to view and describe the spermatozoon. He was not a scientist but it was probably not by chance that he was the chief inspector of weights and measures of the city of Delft reminding us over the centuries that exact methodology is the basis for andrology - as it is of all science. Despite this early start and although spermatozoa have been analysed routinely for the evaluation of fertility since the beginning of this century it took some 300 years until the first guidelines for standardized semen evaluation were published and under the aegis of WHO globally accepted (WHO 1980 1987 1992). Nonetheless spermatology formed the basis of andrology. (excerpt)

Background: Clinical outcomes in large patient populations from real-world clinical practice with a next-generation self-expanding transcatheter aortic valve are lacking.Objectives: This study sought to document the clinical and device performance outcomes of transcatheter aortic valve replacement (TAVR) with a next-generation, self-expanding transcatheter heart valve (THV) system in patients with severe symptomatic aortic stenosis (AS) in routine clinical practice.Methods: The FORWARD (CoreValve Evolut R FORWARD) study is a prospective, single-arm, multinational, multicenter, observational study. An independent clinical events committee adjudicated safety endpoints based on Valve Academic Research Consortium-2 definitions. An independent echocardiographic core laboratory evaluated all echocardiograms. From January 2016 to December 2016, TAVR with the next-generation self-expanding THV was attempted in 1,038 patients with symptomatic, severe AS at 53 centers on 4 continents.Results: Mean age was 81.8 ± 6.2 years, 64.9% were women, the mean Society of Thoracic Surgeons Predicted Risk of Mortality was 5.5 ± 4.5%, and 33.9% of patients were deemed frail. The repositioning feature of the THV was applied in 25.8% of patients. A single valve was implanted in the proper anatomic location in 98.9% of patients. The mean aortic valve gradient was 8.5 ± 5.6 mm Hg, and moderate or severe aortic regurgitation was 1.9% at discharge. All-cause mortality was 1.9%, and disabling stroke occurred in 1.8% at 30 days. The expected-to-observed early surgical mortality ratio was 0.35. A pacemaker was implanted in 17.5% of patients.Conclusions: TAVR using the next-generation THV is clinically safe and effective for treating older patients with severe AS at increased operative risk.

In adults with inflammatory bowel disease (IBD), the incidence of cardiovascular events is increased, leading to long-term morbidity. Arterial stiffness (AS) measured by pulse wave velocity (PWV) is a validated early precursor of cardiovascular disease (CVD), and measurement of PWV was shown to be a feasible test in children. The aim of this study was to assess AS in children with IBD. In this prospective study, we determined PWV between the carotid and femoral artery (PWVcf) in 25 children and adolescents with IBD (11 females, median age 14.1 years, median disease duration 2.8 years). The majority (68%) of the subjects were in clinical remission, and 48% received anti-tumor necrosis factor alpha (TNFα) treatment. AS was not increased in this cohort of children and adolescents with IBD, who did not have signs of cardiovascular disease, such as arterial hypertension.
Conclusion: PWV seems to be normal in children with IBD in remission or with mild disease activity. Larger studies should assess its potential role as a valid and non-invasive follow-up marker in children with IBD, to avoid cardiovascular complications. What is Known : • Inflammatory bowel disease (IBD) is a risk factor of cardiovascular disease (CVD). • Pulse wave velocity (PWV) measurement is the current gold standard to assess arterial stiffness (AS), which is an early predictor of CVD. What is New: • This is the first study using PWV measurements to determine AS in children with IBD. • In children with IBD in remission or only mild disease activity AS is not increased.

Objective: Limited data exist regarding safety and efficacy of antihyperglycemic drugs in older patients with type 2 diabetes. The Trial Evaluating Cardiovascular Outcomes with Sitagliptin (TECOS) was a randomized, double-blind, placebo-controlled trial assessing the impact of sitagliptin on a primary composite outcome of cardiovascular death, nonfatal stroke, nonfatal myocardial infarction, or unstable angina hospitalizations in patients with type 2 diabetes (HbA1c ≥6.5% [48 mmol/mol] and ≤8.0% [64 mmol/mol]) and cardiovascular disease. We analyzed baseline characteristics and clinical outcomes for TECOS participants aged ≥75 years.Research Design and Methods: Clinical and safety event summaries are presented for older versus younger participants and for the treatment groups within the older cohort.Results: Of 14,351 participants with age recorded, 2,004 (14%) were ≥75 years old (mean age 78.3 years [SD 3.1]), with 68% men and type 2 diabetes duration median 12.0 years (IQR 7, 21). During 2.9 years median follow-up, older participants had higher rates of the primary outcome (6.46 vs. 3.67 events per 100 person-years; hazard ratio 1.72 [95% CI 1.52-1.94]), death (2.52 [2.20-2.89]), severe hypoglycemia (1.53 [1.15-2.03]), and fractures (1.84 [1.44-2.35]). In the older cohort, sitagliptin did not significantly impact the primary composite (1.10 [0.89-1.36]), death (1.05 [0.83-1.32]), heart failure hospitalization (0.99 [0.65-1.49]), severe hypoglycemia (1.03 [0.62-1.71]), rates of acute pancreatitis and pancreatic cancer, or serious adverse events.Conclusions: Among older patients with well-controlled type 2 diabetes and cardiovascular disease, sitagliptin had neutral effects on cardiovascular risk and raised no significant safety concerns.

Objectives This longitudinal population study aimed to investigate if maternal depression at different time points during the perinatal period impacts children's social-emotional development at 2 years of age. Methods Participants were women (n = 1235) who gave birth at Akershus University Hospital in Norway. Maternal depressive symptoms were assessed by using the Edinburgh Postnatal Depression Scale at pregnancy week 32 and at 8 weeks and 2 years postpartum, whereas children's social-emotional development at the age of 2 years was assessed by using the Ages and Stages Questionnaire: Social-Emotional. Bi- and multivariate logistic regression analyses were conducted to examine the linkage between maternal perinatal depression and children's early social-emotional development. Results Multivariate analyses showed that social-emotional problems in the child 2 years after birth were strongly associated with maternal depression at pregnancy week 32 (adjusted odds ratio (aOR) 3.4; 95 % CI 1.4-8.0), depression at 8 weeks postpartum (aOR 3.8; 95 % CI 1.7-8.6), and with depression at both time points (aOR 3.7; 95 % CI 1.5-10.1). Conclusion Findings indicate pre- and postnatal depression each bears an independent, adverse impact on children's social-emotional development. [ABSTRACT FROM AUTHOR]

Background: Severe aortic stenosis (AS) is a common, serious valve disease in which no effective medical therapy is available and, if not treated by intervention, has a 5-year survival of only 40-60%. Despite the availability of guidelines supporting the effective use of surgical aortic valve replacement (SAVR) or transcatheter aortic valve implantation (TAVI) to treat the majority of these patients, adherence to these guidelines in clinical practice is still unsatisfactory. Several recent studies have emphasised the necessity for improved communication between multidisciplinary teams, with the aim to ensure that severe AS patients receive appropriate treatment.Methods/design: IMPULSE is a prospective, multicentre, European registry designed to gather data over 12 months on the treatment decisions made by referring physicians for patients newly diagnosed with severe AS. Each patient has a follow-up of 3 months. The study will consist of two observational phases to assess the appropriateness and rate of referral based on current guidelines prior to and after an interventional phase aiming to determine whether a simple quality of care intervention improves patient management.Discussion: Data will be analysed firstly, to determine the appropriateness of treatment decisions for the management of severe AS in current European clinical practice, and secondly, to evaluate the effectiveness of facilitated data relay from a designated echocardiography department nurse to the referring physician early after diagnosis in improving quality of care. Additionally, variables will be identified that are associated with inappropriate decision-making. Collectively, the aim will be to design a clinical pathway that will improve the timely management of patients with newly diagnosed severe AS. [ABSTRACT FROM AUTHOR]- Published

Baylisascaris procyonis roundworms can cause potentially fatal neural larva migrans in many species, including humans. However, the clinical spectrum of baylisascariasis is not completely understood. We tested 347 asymptomatic adult wildlife rehabilitators for B. procyonis antibodies; 24 were positive, suggesting that subclinical baylisascariasis is occurring among this population.

Background: An intense systemic inflammatory response is observed following reperfusion after cardiac arrest. Heparin-binding protein (HBP) is a granule protein released by neutrophils that intervenes in endothelial permeability regulation. In the present study, we investigated plasma levels of HBP in a large population of patients resuscitated from out-of-hospital cardiac arrest. We hypothesized that high circulating levels of HBP are associated with severity of post-cardiac arrest syndrome and poor outcome.Methods: Plasma was obtained from 278 patients enrolled in a prospective multicenter observational study in 21 intensive care units (ICU) in Finland. HBP was assayed at ICU admission and 48 h later. Multiple organ dysfunction syndrome (MODS) was defined as the 24 h Sequential Organ Failure Assessment (SOFA) score ≥ 12. ICU death and 12-month Cerebral Performance Category (CPC) were evaluated. Multiple linear and logistic regression tests and receiver operating characteristic curves with area under the curve (AUC) were performed.Results: Eighty-two percent of patients (229 of 278) survived to ICU discharge and 48 % (133 of 276) to 1 year with a favorable neurological outcome (CPC 1 or 2). At ICU admission, median plasma levels of HBP were markedly elevated, 15.4 [9.6-31.3] ng/mL, and persisted high 48 h later, 14.8 [9.8-31.1] ng/mL. Admission levels of HBP were higher in patients who had higher 24 h SOFA and cardiovascular SOFA score (p < 0.0001) and in those who developed MODS compared to those who did not (29.3 [13.7-60.1] ng/mL vs. 13.6 [9.1-26.2] ng/mL, p < 0.0001; AUC = 0.70 ± 0.04, p = 0.0001). Admission levels of HBP were also higher in patients who died in ICU (31.0 [17.7-78.2] ng/mL) compared to those who survived (13.5 [9.1-25.5] ng/mL, p < 0.0001) and in those with an unfavorable 12-month neurological outcome compared to those with a favorable one (18.9 [11.3-44.3] ng/mL vs. 12.8 [8.6-30.4] ng/mL, p < 0.0001). Admission levels of HBP predicted early ICU death with an AUC of 0.74 ± 0.04 (p < 0.0001) and were independently associated with ICU death (OR [95 %CI] 1.607 [1.076-2.399], p = 0.020), but not with unfavorable 12-month neurological outcome (OR [95 %CI] 1.154 [0.834-1.596], p = 0.387).Conclusions: Elevated plasma levels of HBP at ICU admission were independently associated with early death in ICU.

Several concepts of analytical bias and remedies to minimize bias have been suggested with the ultimate goal to disregard it. Short-term bias (within one control cycle) should be treated as a random error if it is less than the permissible limits. Long-term bias should be eliminated if it is known or circumvented by estimating intra-laboratory reference limits (RLs). Consequently, analytical uncertainty could be reduced to permissible imprecision. Then, models combining imprecision and bias would become irrelevant, and the numerical value of total analytical error would become identical with imprecision. The purpose of the present report is to simplify quality assurance schemes considerably by disregarding bias either by estimating RLs or by verifying the applied reference limits (checking the transferability) as requested by ISO and CLSI.

Objective: The purpose of this study was to compare the short-term effectiveness of three different types of immediate, non-pharmacological intervention for alleviation of the painful symptoms of temporomandibular disorders (TMD).Material and Methods: Thirty-six patients (mean age 41.6 ± 16.7 years, 25 females) diagnosed with non-dysfunctional painful TMD received counselling and subsequently were randomly allocated to three treatment groups: patients in Group A received prefabricated oral splints with water-filled elastic pads (Aqualizer(®)), those in Group B were provided with vacuum-formed co-polyester oral splints and those in Group C were given appointments to receive Michigan-type hard splints. Clinical examination was conducted, at baseline and after 2 weeks, by use of the RDC/TMD. Current pain intensity was determined by evaluation of graded chronic pain status (GCPS) on a numerical rating scale (NRS). Active maximum mouth opening without pain (AMMOP) was also measured. Paired sample t-tests and one-way analysis of variance with a significance level of p ≤ 0.05 were conducted.Results: After 2 weeks, overall mean current pain was reduced by 41.95% (p < 0.001). Current pain reduction was significant for Group B (66.6%, p < 0.001) but not for Groups A (37.88%, p = 0.56) and C (22.29%, p = 0.26). After 2 weeks, current pain level for Group B was significantly lower than that for Group C (p = 0.041). Overall, there was a statistically significant increase of AMMOP (p = 0.01).Conclusion: All therapeutic options were pain-reducing. The results from this study suggest that cost-effective and time-effective intervention of counselling combined with use of a vacuum-formed splint is a favourable option for initial, short-term treatment of painful TMD.

Background: Demographic change influences not only the terms of health care, but also its financing. Hence, prevention is becoming a more important key to facing upcoming challenges. Aim of this study was to identify predictors for future high-cost patients and derive implications for potential starting points for prevention. Methods: Claims data from a German statutory health insurance agency were used. High-cost patients were defined as the 10% most expensive persons to insure in 2011. The predictors stemmed from the previous year. Logistic regression with stepwise forward selection for 10 sex- and age-specific subgroups was performed. Model fit was assessed by Nagelkerke's R-squared value. Results: Model fit values indicated well-suited models that yielded better results among younger age-groups. Identified predictors can be summarized as different sets of variables that mostly pertain to diseases. Some are rather broad and include different disorders, like the set of mental/behavioural disorders including depression and schizophrenia; other sets of variables are more homogenous, such as metabolic diseases, with diabetes mellitus (DM) being the dominant member of every subgroup. Conclusion: Because diabetes was a significant predictor for future high-cost patients in all analysed subgroups, it should be considered as a potential starting point for prevention. The disease is specific enough to allow for the implementation of effective prevention strategies, and it is possible to intervene, even in patients already affected by DM. Furthermore, the monetary savings potential is probably high because the long-term complications of DM are expensive to treat and affect a large part of the population. [ABSTRACT FROM AUTHOR]

Objective: The small size of many pediatric rheumatology programs translates into limited mentoring options for early career physicians. To address this problem, the American College of Rheumatology (ACR) and the Childhood Arthritis and Rheumatology Research Alliance (CARRA) developed a subspecialty-wide interinstitutional mentoring program, the ACR/CARRA Mentoring Interest Group (AMIGO). We sought to assess the impact of this program on mentoring within pediatric rheumatology.Methods: In a longitudinal 3-year study, participant ratings from the AMIGO pilot program were compared with those after the program was opened to general enrollment. Access to mentoring as a function of career stage was assessed by surveys of the US and Canadian pediatric rheumatologists in 2011 and 2014, before and after implementation of AMIGO.Results: Participants in the pilot phase (19 dyads) and the general implementation phase (112 dyads) reported comparable success in establishing mentor contact, suitability of mentor-mentee pairing, and benefit with respect to career development, scholarship, and work-life balance. Community surveys showed that AMIGO participation as mentee was high among fellows (86%) and modest among junior faculty (31%). Implementation correlated with significant gains in breadth of mentorship and in overall satisfaction with mentoring for fellows but not junior faculty.Conclusion: AMIGO is a career mentoring program that serves most fellows and many junior faculty in pediatric rheumatology across the US and Canada. Program evaluation data confirm that a subspecialty-wide interinstitutional mentoring program is feasible and can translate into concrete improvement in mentoring, measurable at the level of the whole professional community.

Objective: To validate clinical indices of lupus nephritis activity and damage when used in children against the criterion standard of kidney biopsy findings.Methods: In 83 children requiring kidney biopsy, the Systemic Lupus Erythematosus Disease Activity Index renal domain (SLEDAI-R), British Isles Lupus Assessment Group index renal domain (BILAG-R), Systemic Lupus International Collaborating Clinics (SLICC) renal activity score (SLICC-RAS), and SLICC Damage Index renal domain (SDI-R) were measured. Fixed effects and logistic models were calculated to predict International Society of Nephrology/Renal Pathology Society (ISN/RPS) class; low-to-moderate versus high lupus nephritis activity (National Institutes of Health [NIH] activity index [AI]) score: ≤10 versus >10; tubulointerstitial activity index (TIAI) score: ≤5 versus >5; or the absence versus presence of lupus nephritis chronicity (NIH chronicity index) score: 0 versus ≥1.Results: There were 10, 50, and 23 patients with ISN/RPS class I/II, III/IV, and V, respectively. Scores of the clinical indices did not differentiate among patients by ISN/RPS class. The SLEDAI-R and SLICC-RAS but not the BILAG-R differed with lupus nephritis activity status defined by NIH-AI scores, while only the SLEDAI-R scores differed between lupus nephritis activity status based on TIAI scores. The sensitivity and specificity of the SDI-R to capture lupus nephritis chronicity was 23.5% and 91.7%, respectively. Despite being designed to measure lupus nephritis activity, SLICC-RAS and SLEDAI-R scores significantly differed with lupus nephritis chronicity status.Conclusion: Current clinical indices of lupus nephritis fail to discriminate ISN/RPS class in children. Despite its shortcomings, the SLEDAI-R appears best for measuring lupus nephritis activity in a clinical setting. The SDI-R is a poor correlate of lupus nephritis chronicity.

To determine the frequency, imaging characteristics, neuroanatomical distribution and dynamics of magnetic resonance imaging findings in HIV-associated cryptococcal meningitis in immunocompromised patients we compared patients without antiretroviral therapy with patients undergoing immune reconstitution. Neuroimaging and clinical data of 21 consecutive patients presenting to a German HIV centre in a 10-year period between 2005 and 2014 were reviewed. We identified eight patients with magnetic resonance imaging findings related to cryptococcal disease: five patients without antiretroviral therapy and three patients receiving effective antiretroviral therapy resulting in immune reconstitution. The pattern of magnetic resonance imaging manifestations was different in the two groups. In patients not on antiretroviral therapy, pseudocysts (n = 3) and lacunar ischaemic lesions (n = 2) were detected. Contrast-enhancing focal leptomeningeal and/or parenchymal lesions were found in all patients under immune reconstitution (n = 3). Magnetic resonance imaging lesions suggestive of leptomeningitis or meningoencephalitis were detected in all patients with a recurrence of cryptococcal meningitis under immune reconstitution, which differs from the classical magnetic resonance imaging findings in patients without antiretroviral therapy. In antiretroviral therapy-treated patients with past medical history of cryptococcal meningitis, detection of contrast-enhancing focal meningeal and/or parenchymal lesions should prompt further investigations for a recurrence of cryptococcal meningitis under immune reconstitution.

Objectives: The aim of this study was to develop valid and reliable disease-specific questionnaires for adult patients with cystic fibrosis and for parents of minors with cystic fibrosis for assessing patient experience with cystic fibrosis care. Methods: The pilot versions of the questionnaires were developed based on a literature review, interviews with health professionals and focus groups. A postal survey with two reminders was conducted in 56 German cystic fibrosis centres recruiting 2874 participants. Psychometric evaluation was done via exploratory factor analysis and reliability and regression analysis. The questionnaires' ability to differentiate between subgroups and between cystic fibrosis centres was evaluated. Results: Response rates were 74% for both adult patients and parents. Ten factors were extracted for both the adult and the parents' models (Cronbach's alpha between 0.6 and 0.9), explaining 50% and 48% of the variance, respectively. The factors organisation & access and the doctor-patient/ parent-interaction had the highest relevance for a good overall care experience. The questionnaires were able to distinguish between different cystic fibrosis centres. Discussion: The questionnaires are well suited for use in internal and external quality management of cystic fibrosis care due to their good psychometric properties, the ability to differentiate between centres and its practicability.

Background Integrative medicine (IM) integrates evidence-based Complementary and Alternative Medicine (CAM) with conventional medicine (CON). Medical schools offer basic CAM electives but in postgraduate medical training (PGMT) little has been done for the integration of CAM. An exception to this is anthroposophic medicine (AM), a western form of CAM based on CON, offering an individualized holistic IM approach. AM hospitals are part of the public healthcare systems in Germany and Switzerland and train AM in PGMT. We performed the first quality evaluation of the subjectively perceived quality of this PGMT.Methods An anonymous full survey of all 215 trainers (TR) and 230 trainees (TE) in all 15 AM hospitals in Germany and Switzerland, using the ETHZ questionnaire for annual national PGMT assessments in Switzerland (CH) and Germany (D), complemented by a module for AM. Data analysis included Cronbach's alpha to assess internal consistency questionnaire scales, 2-tailed Pearson correlation of specific quality dimensions of PGMT and department size, 2-tailed Wilcoxon Matched-Pair test for dependent variables and 2-tailed Mann- Whitney U-test for independent variables to calculate group differences. The level of significance was set at p < 0.05. Results Return rates were: D: TE 89/215 (41.39%), TR 78/184 (42.39%); CH: TE 19/25 (76%), TR 22/30 (73.33%). Cronbach's alpha values for TE scales were >0.8 or >0.9, and >0.7 to >0.5 for TR scales >0.7 to >0.5. Swiss hospitals surpassed German ones significantly in Global Satisfaction with AM (TR and TE); Clinical Competency training in CON (TE) and AM (TE, TR), Error Management, Culture of Decision Making, Evidence-based Medicine, and Clinical Competency in internal medicine CON and AM (TE). When the comparison was restricted to departments of comparable size, differences remained significant for Clinical Competencies in AM (TE, TR), and Culture of Decision Making (TE). CON received better grades than AM in Global Satisfaction and Clinical Competency. Quality of PGMT depended on department size, working conditions and structural training features. Conclusion The lower quality of PGMT in German hospitals can be attributed to larger departments, more difficult working conditions, and less favorable structural features for PGMT in AM, possibly also in relation to increased financial pressure.

The present study was aimed to explore the in vivo application of CLSM in experimentally induced gingivitis. Materials and Methods Ten subjects were recruited and were advised to stop any oral hygiene of the upper front teeth for 7 days. The gingival tissues were observed using a Heidelberg Retina Tomograph combined with a Rostock Cornea Module at baseline and day 7. The system used a laser of 670 nm and the contrast was given by backscattering from different tissues. Each examination created 800-1200 images that were descriptively analysed. Results After 7 days of abandoned oral hygiene, plaque scores and bleeding frequencies increased. By using CLSM images tooth hard substances, cells and plaque deposits were distinguishable. Increased epithelial cell irregularities, the apical migration of the sulcular epithelium, cellular infiltrates within the sulcus and plaque deposits were observed at day 7. Conclusions The present study showed for the first time that CLSM is suitable for in vivo imaging of the gingival sulcus and adjacent tissues. [ABSTRACT FROM AUTHOR]

Background The aim of this prospective study was to investigate the role of labor pain and overall birth experience in the development of posttraumatic stress symptoms in a comprehensive framework. Methods The study sample ( N = 1893) comprised women with a vaginal delivery and was drawn from the Akershus Birth Cohort, which targeted all women scheduled to give birth at Akershus University Hospital in Norway. Questionnaires were given at three different stages: from pregnancy weeks 17 to 32, from the maternity ward, and from 8 weeks postpartum. Data were also obtained from the hospital's birth record. Using structural equation modeling, a prospective mediation model was tested. Results Posttraumatic stress symptoms were significantly related to both labor pain ( r = 0.23) and overall birth experience ( r = 0.39). A substantial portion (33%) of the effect of labor pain on posttraumatic stress symptoms was mediated by the overall birth experience. Conclusions Although the results of this study showed that both labor pain and overall birth experience played a role in the development of posttraumatic stress symptoms after childbirth, overall birth experience appeared to be the central factor. The women's birth experience was not only related to posttraumatic stress symptoms directly but also mediated a substantial portion of the effect of labor pain on posttraumatic stress symptoms. Future work should address which areas of birth experience confer protective effects on women to improve clinical care. [ABSTRACT FROM AUTHOR]

Introduction: Anorectal malformations (ARM) range from mild anal to severe anorectal anomalies. Approximately 50% are estimated to be non-syndromic with multiple familial cases reported that suggest underlying genetic factors. These, however, still await identification.Materials and Methods: We report a familial case of non-syndromic ARM with a mother and her two children being affected. Mother and daughter had mild ARM that had only been diagnosed after the index patient was born with a more severe form and ultrashort Hirschsprung's disease. To reveal the genetic cause in our family genome-wide array analysis was carried out to ascertain microaberrations characterized by loss or gain of genomic material. In addition, sequence analysis of four major Hirschsprung's disease genes (RET, EDNRB, EDN3, and GDNF) and the HLXB9 gene was performed to identify a mutation common to all three family members; however, these analyses did not reveal any causal genetic alteration. To demonstrate the frequency of familial non-syndromic cases, we performed a literature search revealing 59 families with at least two affected members. Sufficient description of ARM phenotype and affection status of relatives to surely classify them as familial non-syndromic forms was given for 22 families.Conclusion: The present family suggests that mild ARM may be overlooked in patients with non-specific clinical symptoms and that the incidence of ARM may thus be higher than previously estimated. With the new possibilities of whole exome sequencing, even small families hold the possibility to identify causal defects. [ABSTRACT FROM AUTHOR]- Published

Purpose: The recently established International Consortium on Anorectal Malformations aims to identify genetic and environmental risk factors in the etiology of syndromic and nonsyndromic anorectal malformations (ARM) by promoting collaboration through data sharing and combined research activities.Methods: The consortium attempts to recruit at least 1,000 ARM cases. DNA samples are collected from case-parent triads to identify genetic factors involved in ARM. Several genetic techniques will be applied, including SNP arrays, gene and whole exome sequencing, and a genome-wide association study. Questionnaires inquiring about circumstances before and during pregnancy will be used to obtain environmental risk factor data.Results: Currently, 701 ARM cases have been recruited throughout Europe. Clinical data are available from all cases, and DNA samples and questionnaire data mainly from the Dutch and German cases. Preliminary analyses on environmental risk factors in the Dutch and German cohort found associations between ARM and family history of ARM, fever during first trimester of pregnancy and maternal job exposure to cleaning agents and solvents.Conclusion: First results show that both genetic and environmental factors may contribute to the multifactorial etiology of ARM. The International Consortium on Anorectal Malformations will provide possibilities to study and detect important genes and environmental risk factors for ARM, ultimately resulting in better genetic counseling, improved therapies, and primary prevention.

There has been growing recognition of a changing clinical presentation of celiac disease (CD), with the manifestation of milder symptoms. Serologic testing is widely used to screen patients with suspected CD and populations at risk. The aim of this retrospective analysis was to evaluate the clinical presentation of CD in childhood, assess the diagnostic value of serologic tests, and investigate the impact of IgA deficiency on diagnostic accuracy. We evaluated 206 consecutive children with suspected CD on the basis of clinical symptoms and positive serology results. Ninety-four (46%) had biopsy-proven CD. The median age at diagnosis of CD was 6.8 years; 15% of the children were <2 years of age. There was a higher incidence of CD in girls (p = 0.003). Iron deficiency and intestinal complaints were more frequent in children with CD than those without CD (61% vs. 33%, p = 0.0001 and 71% vs. 55%, p = 0.02, respectively), while failure to thrive was less common (35% vs. 53%, p = 0.02). The sensitivity of IgA tissue transglutaminase (IgA-tTG) was 0.98 when including all children and 1.00 after excluding children with selective IgA deficiency. The specificity of IgA-tTG was 0.73 using the recommended cut-off value of 20 IU, and this improved to 0.94 when using a higher cut-off value of 100 IU. All children with CD and relative IgA deficiency (IgA levels that are measurable but below the age reference [n = 8]) had elevated IgA-tTG. In conclusion, CD is frequently diagnosed in school-age children with relatively mild symptoms. The absence of intestinal symptoms does not preclude the diagnosis of CD; many children with CD do not report intestinal symptoms. While the sensitivity of IgA-tTG is excellent, its specificity is insufficient for the diagnostic confirmation of a disease requiring life-long dietary restrictions. Children with negative IgA-tTG and decreased but measurable IgA values are unlikely to have CD. [ABSTRACT FROM AUTHOR]

A potential treatment for paralysis resulting from spinal cord injury is to route control signals from the brain around the injury by artificial connections. Such signals could then control electrical stimulation of muscles, thereby restoring volitional movement to paralysed limbs. In previously separate experiments, activity of motor cortex neurons related to actual or imagined movements has been used to control computer cursors and robotic arms, and paralysed muscles have been activated by functional electrical stimulation. Here we show that Macaca nemestrina monkeys can directly control stimulation of muscles using the activity of neurons in the motor cortex, thereby restoring goal-directed movements to a transiently paralysed arm. Moreover, neurons could control functional stimulation equally well regardless of any previous association to movement, a finding that considerably expands the source of control signals for brain-machine interfaces. Monkeys learned to use these artificial connections from cortical cells to muscles to generate bidirectional wrist torques, and controlled multiple neuron–muscle pairs simultaneously. Such direct transforms from cortical activity to muscle stimulation could be implemented by autonomous electronic circuitry, creating a relatively natural neuroprosthesis. These results are the first demonstration that direct artificial connections between cortical cells and muscles can compensate for interrupted physiological pathways and restore volitional control of movement to paralysed limbs.

Background: Exposure to violence has been shown to have an impact on somatic health. However, our knowledge about the possible dose-response relationship between frequency of violence exposure and health is still limited.Objective: To study the associations between recent and repetitive exposure to violence and presence of somatic symptoms and diseases in women.Design: Cross-sectional, community-based, self-reporting survey.Participants: Two thousand seven hundred thirty women aged 18-40 years (mean age 30.5 years).Measurements: The somatic symptom scale derived from the Primary Care Evaluation of Mental Disorders was used to obtain information on the presence of somatization. In addition, we asked about the presence of 11 diseases or organ-specific diseases. Exposure to violence was measured by the Abuse Assessment Screen.Results: Eighteen percent (486/2,730) of women surveyed reported exposure to physical violence. Three percent (94/2,730) had been forced into sexual intercourse as an adult. All somatic symptoms, and several diseases, were significantly more common in women exposed to physical and/or sexual violence as compared to nonexposed women. Women exposed to 3 or more violent episodes in the past 12 months reported a presence of 4.8 somatic symptoms and 1.2 diseases (mean) as compared to 1.8 symptoms and 0.5 diseases in nonexposed women. Women with exposure to both physical and sexual violence reported 6.0 symptoms and 1.5 diseases. The impact of violence on somatic symptoms and diseases remained after controlling for depression and sociodemographic factors.Conclusions: Violence was associated with the presence of somatic symptoms and diseases. The more a woman is exposed to violence, the higher the number of somatic symptoms and diseases reported is. [ABSTRACT FROM AUTHOR]- Published

The forward bending test according to Adams and rib hump quantification by scoliometer are common clinical examination techniques in idiopathic scoliosis, although precise data about the change of axial surface rotation in forward bending posture are not available. In a pilot study the influence of leg length inequalities on the back shape of five normal subjects was clarified. Then 91 patients with idiopathic scoliosis with Cobb-angles between 20° and 82° were examined by rasterstereography, a 3D back surface analysis system. The axial back surface rotation in standing posture was compared with that in forward bending posture and additionally with a scoliometer measurement in forward bending posture. The changes of back shape in forward bending posture were correlated with the Cobb-angle, the level of the apex of the scoliotic primary curve and the age of the patient. Averaged over all patients, the back surface rotation amplitude increased from 23.1° in standing to 26.3° in forward bending posture. The standard deviation of this difference was high (6.1°). The correlation of back surface rotation amplitude in standing with that in forward bending posture was poor ( R 2=0.41) as was the correlation of back surface rotation in standing posture with the scoliometer in forward bending posture measured rotation ( R 2=0.35). No significant correlation could be found between the change of back shape in forward bending and the degree of deformity ( R 2=0.07), likewise no correlation with the height of the apex of the scoliosis ( R 2=0.005) and the age of the patient ( R 2=0.001). Before forward bending test leg length inequalities have to be compensated accurately. Compared to the standing posture, forward bending changes back surface rotation. However, this change varies greatly between patients, and is independent of the type and degree of scoliosis. Furthermore remarkable differences were found between scoliometer measurement of the rib hump and rasterstereographic measurement of the vertebral rotation. Therefore the forward bending test and the identification of idiopathic scoliosis rotation by scoliometer can be markedly different compared to rasterstereographic surface measurement in the standing posture.

We wanted to search for the mechanism(s) responsible for the brief pressor response induced by anandamide in urethane-anaesthetized rats.The anandamide-induced pressor effect was not modified by the antagonists of cannabinoid CB
1 and vanilloid TRPV1 receptors, SR 141716A (3 μmol kg−1 ) and capsazepine (1 μmol kg−1 ), respectively, by bilateral vagotomy and by pithing. Replacement of urethane by pentobarbitone virtually abolished the pressor effect of anandamide, both in pithed and vagotomized and in ‘intact’ rats (i.e. not treated in this manner).The pressor effect of anandamide was reduced by the nonselective TRPV family inhibitor ruthenium red (3 μmol kg−1 ) and by the blocker of L-type calcium channels nifedipine (1 μmol kg−1 ), both in pithed urethane-anaesthetized rats and in ‘intact’ urethane-anaesthetized rats. The nonselective β-adrenoceptor antagonist propranolol (0.1 or 0.3 μmol kg−1 ) and the nonselective NMDA receptor antagonist MK-801 (1 μmol kg−1 ) diminished the anandamide-induced vasopressor response in ‘intact’ but not in pithed rats. The inhibitory effect of propranolol in ‘intact’ rats was mimicked by the β2 -adrenoceptor antagonist ICI 118551 (1 μmol kg−1 ), but not by the β1 -adrenoceptor antagonist CGP 20712 (1 μmol kg−1 ).The present study revealed that two mechanisms may be responsible for the anandamide-induced pressor response in urethane-anaesthetized rats. The first involves the central nervous system (probably the medulla oblongata) and is sensitive to propranolol and MK-801. The second, which is located peripherally (most probably in blood vessels), is sensitive to nifedipine, ruthenium red and pentobarbitone and, hence, probably represents a Ca2+ -dependent mode of action.British Journal of Pharmacology (2005) 145, 567–575. doi:10.1038/sj.bjp.0706195 Published online 18 April 2005 [ABSTRACT FROM AUTHOR]- Published

Mood disorders in pregnancy may have a negative effect on self care and pregnancy outcome that affects the mother directly and the child indirectly. Thus, some women may require pharmacological treatment. Pharmacotherapy of mood disorders during pregnancy implies specific considerations. This paper presents an updated review of available studies on the treatment of mood disorders and present knowledge on teratogenicity, neonatal effects and long-term neurobehavioural effects for the different psychotropic drugs, including treatment with selective serotonin reuptake inhibitors (SSRIs), tricyclic antidepressants (TCAs), other antidepressants, benzodiazepines, lithium, carbamazepine/valproic acid, lamotrigine and novel antipsychotics. However, the existing knowledge on the use of antidepressants and mood stabilising agents during pregnancy is hampered by a lack of results from randomised controlled trials.SSRIs and TCAs have not been associated with an increased risk of major malformations, but poor neonatal adaptation has been described. Benzodiazepines used in the first trimester have been associated with orofacial clefts. Mood stabilisers such as lithium, carbamazepine and valproic acid (sodium valproate) are associated with an increased risk of fetal malformations. Both benzodiazepines and lithium may cause adaptation problems in the newborn. In utero exposure to novel antipsychotics has not been associated with congenital malformations; however, the data are still limited. The knowledge about long-term neurobehavioural effects in the offspring is still limited for all agents and requires further investigation. Possible adverse effects of fetal exposure must be balanced against the adverse effects of an untreated maternal mood disorder. [ABSTRACT FROM AUTHOR]

Background: The primary endpoint of this study was to evaluate the effects of low-dose atorvastatin on carotid intima-media thickness (IMT) and endothelial function, and the secondary endpoint comprised restenosis and target lesion revascularization (TLR) in patients undergoing percutaneous coronary intervention (PCI) with stenting for the treatment of coronary artery disease.Methods: Two hundred five consecutive patients (mean age, 60 years) undergoing PCI were prospectively randomized to usual therapy (control group, n = 100) or to 10 mg of atorvastatin daily plus usual therapy (statin group, n = 105). Carotid IMT, endothelial function (flow-mediated dilatation [FMD] of the brachial artery), and coronary angiograms were taken before the study and 6 months after randomization. The 6-month follow-up measurements of the above factors were obtained in 83 patients (83%) of the control group and in 97 patients (92%) of the statin group.Results: No significant differences were noted in the baseline clinical and angiographic findings in either group. FMD was significantly improved during the 6 months in the statin group (4.38% +/- 1.7% vs 4.85% +/- 1.6%, P = .003), but did not change in the control group. Carotid IMT did not show any significant changes at 6 months in either group. There was a trend in favor of statin in terms of restenosis rate (26.8% vs 36.1%, P = .177) and TLR rate (18.6% vs 25.3%, P = .274). The changes of FMD were significantly correlated with the changes of total cholesterol and the changes of low-density lipoprotein, respectively (r = -0.336, P = .009, and r = -0.310, P = .046).Conclusion: Low-dose atorvastatin reduces endothelial dysfunction as measured by FMD, which coincides with the beneficial effects on lipid profiles, and can decrease restenosis and TLR rate in patients undergoing PCI with stenting.

1. Our study was undertaken to investigate whether bacterial endotoxin/lipopolysaccharide (LPS) affects the neurogenic vasopressor response in rats in vivo by presynaptic mechanisms and, if so, to characterize the type of presynaptic receptor(s) operating in the initial phase of septic shock. 2. In pithed and vagotomized rats treated with pancuronium, electrical stimulation (ES) (1 Hz, 1 ms, 50 V for 10 s) of the preganglionic sympathetic nerve fibers or intravenous bolus injection of noradrenaline (NA) (1-3 nmol x kg(-1)) increased the diastolic blood pressure (DBP) by about 30 mmHg. Administration of LPS (0.4 and 4 mg x kg(-1)) under continuous infusion of vasopressin inhibited the neurogenic vasopressor response by 25 and 50%, respectively. LPS did not affect the increase in DBP induced by exogenous NA. 3. The LPS-induced inhibition of the neurogenic vasopressor response was counteracted by the cannabinoid CB(1) receptor antagonist SR 141716A (0.1 micromol x kg(-1)), but not by the CB(2) receptor antagonist SR 144528 (3 micromol x kg(-1)), the vanilloid VR1 receptor antagonist capsazepine (1 micromol x kg(-1)) or the histamine H(3) receptor antagonist clobenpropit (0.1 micromol x kg(-1)). The four antagonists by themselves did not affect the increase in DBP induced by ES or by injection of NA in rats not exposed to LPS. 4. We conclude that in the initial phase of septic shock, the activation of presynaptic CB(1) receptors by endogenously formed cannabinoids contributes to the inhibition of the neurogenic vasopressor response.

Objective: To investigate whether the electroencephalogram (EEG)-based Patient State Index (PSI) indicates the level of sedation as measured by Ramsay score in intubated and mechanically ventilated patients in the ICU.Design: Prospective, single-blinded observer study.Setting: Surgical intensive care unit.Patients: Forty-one consecutive adult patients requiring intubation and ventilation during intensive care therapy.Measurements and Results: Following skin preparation with alcohol and placement of EEG electrodes, PSI was recorded while patients were ventilated and sedated with constant drug infusion rates. After 30 min, the level of sedation was measured by an assessor, who was blinded to PSI values, using the Ramsay sedation score. For analysis, the mean of PSI values measured during the last minute before clinical assessment of sedation was calculated. General Linear Model (GLM) analysis revealed significant differences between the PSI values at different levels of sedation as measured by the Ramsay score, except for the differentiation of level 5 from levels 4 and 6 (p>0.3) and level 2 from level 3, where only a trend was reached (p=0.077). The prediction probability of PSI was 0.920+/-0.037.Conclusion: As the high prediction probability and the analysis of paired comparisons suggest, PSI may be used to quantify the level of propofol/sufentanil sedation in ICU patients. Further studies are required to test whether these promising results can be verified for other drug combinations. [ABSTRACT FROM AUTHOR]- Published

Background: ICSI into the oocyte is the only treatment currently available for most male patients with severe oligozoospermia who wish to father children. In order to perform ICSI, motile sperm need to be recovered from the ejaculate and, if no sperm or not enough motile sperm are recovered on the day of ICSI, testicular sperm extraction (TESE) must be performed. Oxytocin stimulates epididymal contractility and may be important for the release of stored sperm. The aim of this randomized single-blind cross-over study was to establish the effects of oxytocin on sperm output in severely oligozoospermic men.Methods: Forty-nine infertile men with sperm concentrations <0.2 x 10(6)/ml were studied on two occasions after 3-4 days of sexual abstinence. They received an i.v. injection of saline or oxytocin 0.75 IU in random order, and commenced masturbation within 5 min. Ejaculate analysis was performed according to the WHO 1999 guidelines.Results: A single i.v. dose of oxytocin resulted in no change in ejaculate volume (P = 0.4), total sperm count (P = 0.14) or sperm motility (P = 0.9). There was no significant correlation between the change in total sperm count and FSH levels (r = -0.32, P = 0.2), or the change in total sperm count and estradiol levels (r = -0.02, P = 0.9). Similar results were found in a subgroup of men with total sperm counts of <100.Conclusions: Our data indicate that a single-dose of i.v. oxytocin has no detectable effect on seminal parameters in men with severe oligozoospermia.

Oxidized LDL (oxLDL) is a key mediator in atherogenesis and a marker of coronary artery disease (CAD). Type 2 diabetes is associated with excessive cardiovascular morbidity and mortality. Because atherogenesis starts before diabetes is diagnosed, we investigated whether circulating oxLDL levels are increased in impaired glucose tolerance (IGT). OxLDL levels were measured in 376 subjects with normal glucose tolerance (NGT), 113 patients with IGT, and 54 patients with newly diagnosed type 2 diabetes. After correction for age and BMI, serum levels of oxLDL were significantly increased in IGT versus NGT subjects (P = 0.002). OxLDL levels were not associated with the following parameters of the oxidative/antioxidative balance in the blood: total antioxidant capacity, urate-to-allantoin ratio, and circulating phagocyte oxygenation activity. In stepwise multivariate analysis, LDL cholesterol (P < 0.0005) and triglycerides (P < 0.0005) were the strongest predictors of circulating oxLDL levels, followed by HDL cholesterol (P = 0.003), 2-h postchallenge C-peptide (P = 0.011), fasting free fatty acids (P = 0.013), and serum paraoxonase activity (P = 0.035). The strong correlation of oxLDL with LDL cholesterol and triglycerides indicates that LDL oxidation in IGT is preferentially associated with dyslipidemia. OxLDL increase may explain the high atherogenic potency of dyslipidemia in the prediabetic state. [ABSTRACT FROM AUTHOR]

Distal embolization after angioplasty in degenerated saphenous vein grafts (SVGs) results in high rates of periprocedural myonecrosis and mortality. Temporary protection of the distal microcirculation with aspiration of dislodged debris may improve the safety of SVG intervention. To evaluate the feasibility, safety, and efficacy of distal protection using the PercuSurge GuardWire Occlusion and Aspiration System, 103 consecutive patients undergoing planned stenting of 105 SVG lesions were prospectively enrolled in a multinational, multicenter study. Before angioplasty, protection of the distal circulation was achieved with the PercuSurge GuardWire distal balloon occlusion system, followed by stenting and debris aspiration. Quality assurance measures in the study included independent on-site data monitoring, clinical event adjudication, data analysis, and use of multiple core laboratories. Mean graft age was 8.9 ± 4.0 years. The duration of distal balloon inflation was 5.4 ± 3.7 minutes; premature balloon deflation for ischemia was not required in any patient. Macroscopically visible red and/or yellow debris was extracted in 91% of patients. By core lab analysis, postprocedural Thrombolysis In Myocardial Infarction-III flow was present in 98.9% of grafts (vs 83.5% before intervention). No patient developed angiographic evidence of no reflow or distal embolization. Postprocedural creatine phosphokinase MB isozyme levels were elevated to >3 × normal in only 5 patients (5%), and 97 patients (94%) were free of major adverse events at 30 days. We conclude that the GuardWire distal balloon occlusion and aspiration system is an effective and safe method for protecting distal microcirculation from the adverse consequences of embolization during mechanical intervention of degenerated SVGs.

Purpose: A new hemostatic puncture closure device (HPCD) was evaluated following femoropopliteal angioplasty. Efficacy in hemostasis and complications were compared between manual compression and the new system.Methods: One hundred patients undergoing percutaneous interventional procedures were randomly assigned to receive either manual compression or HPCD. The time to complete hemostasis (when a compression bandage was applied) was noted as well as complications such as hematoma or arterial stenosis at the puncture site. Follow-up was by clinical examination and color-coded duplex sonography (CCDS).Results: With the HPCD, immediate hemostasis was achieved in 22 patients (44%). Discrete oozing without the necessity of external compression or further consequences was observed in 11 patients. Mean manual compression time was 25 (+/- 20) min including application of the pressure bandage. Eleven patients needed additional manual compression and technical failures were observed in 6 patients (12%). The compression time in these 17 cases was 27 (+/- 12) min. Subcutaneous hematomata with a diameter of more than 5 cm developed in 15 of 48 patients in the HPCD group and in 14 of 48 patients in the manual compression group. No surgical or percutaneous intervention was necessary. The complication rate was comparably low in the experimental and control groups.Conclusion: Compared with manual compression HPCD is faster and more accurate for sealing the arterial puncture defect following angioplasty. After an initial learning curve, it is easy to handle and time-saving as well as convenient for the patient. Furthermore, immediate and full anticoagulation is possible and arterial inflow is not compromised. A drawback is the necessity of an 8 Fr sheath. Nevertheless, the complication rate is comparably low for both methods. [ABSTRACT FROM AUTHOR]- Published

We evaluated the diagnostic accuracy and complications of digital subtraction angiography (DSA) in a series of clinical trials conducted on patients primarily with cerebral vascular disease and those evaluated before and after surgery or percutaneous transluminal angioplasty. Double-blind studies of the carotid-vertebral arteries of 300 of the 2,200 patients using DSA imaging and a variety of ionic and nonionic contrast agents showed that although subjects tolerated the injection of nonionic contrast better than ionic, nonionic contrast administration did not lead to better image quality. Of 764 patients receiving ionic contrast media, 3.3% had mild-to-serve adverse reactions; of 350 injected with nonionic contrast agents, 1.7% had mild-to-severe adverse reactions. If the sole consideration is safety, use of ionic contrast media is justified. [ABSTRACT FROM AUTHOR]

Development of male external genitalia is dependent on androgens, and karyotypic males lacking appropriate levels of androgens or functionally normal receptors may show abnormal virilization. Mutations in the androgen receptor gene cause abnormal receptor function and diverse mutations may be associated with heterogeneous clinical signs of androgen insensitivity. In this study, we have searched for the existence of androgen receptor gene mutations carried by some patients with hypospadias. Genomic DNA samples from peripheral blood leucocytes from 21 patients with different degrees of hypospadias were studied. Analysis of the androgen receptor gene was performed by exon-specific amplification using polymerase chain reaction, single strand conformation polymorphism analysis, and direct genomic sequencing. Although a silent polymorphism was identified in exon 1 of the androgen receptor gene, the majority of patients studied (20/21) did not carry androgen receptor gene mutations. One patient with severe hypospadias and bilateral cryptorchidism was found to carry a point mutation in exon 8. We conclude that mutations in the androgen receptor gene may be carried by subset of patients with genital ambiguity presenting primarily with hypospadias, but this is not the underlying cause in the majority of cases. Characterization of this genetic defect may be important for classification and subsequent conservative therapeutic approaches for these patients. [ABSTRACT FROM AUTHOR]
