    Full Text Available Aims: To investigate the outcomes of the surgical management and longitudinal assessment of patients with subclinical Cushing′s syndrome (SCS and nonfunctioning adrenocortical adenoma (NFA. Materials and Methods: Between the years 1995 and 2008, 73 patients with asymptomatic adrenocortical adenoma were enrolled. They were informed of the risks and benefits of adrenalectomy and conservative management, and then chose the treatment. Results: SCS was observed in 13 patients (17.8% and NFA in 60 patients (82.2%. Tumor size in SCS was significantly larger than that in NFA (34.6 ± 9.7 mm vs. 24.5 ± 8.0 mm in diameter, P=0.001. Of the SCS patients, 7 also suffered from hypertension (HT, 2 from diabetes mellitus (DM and 3 from hyperlipidemia (HL. After adrenalectomy, the insulin dose could be reduced in 2 (100% patients with DM, in 5 (71.4% of those with HT and in 2 (66.7% of those with HL. In the NFA surveillance group, 1 (2.6% case developed into SCS 3 years after the initial presentation and an increase in size of the tumor was observed in 1 (2.6%, with a mean follow-up of 51.2 months. Conclusions: Surgical resection may be beneficial for the control of SCS and is likely to provide improvement of concomitant HT, DM and HL. Although NFA can be managed conservatively, its size and hormonal activities may change longitudinally. Thus, long-term follow-up is necessary for NFA.

    Previous studies examining early readmission after acute myocardial infarction have focused exclusively on inpatient readmissions. However, from a patient's perspective, any unplanned inpatient or observation rehospitalization after acute myocardial infarction represents a significant event; these unplanned rehospitalizations have not been well characterized. We examined all patients with acute myocardial infarction treated with percutaneous coronary intervention and discharged alive from 233 hospitals in the Treatment With Adenosine Diphosphate Receptor Inhibitors: Longitudinal Assessment of Treatment Patterns and Events After Acute Coronary Syndrome (TRANSLATE-ACS) study from 2010 to 2012. Our primary outcome was unplanned rehospitalizations (inpatient or observation status) within 30 days after discharge. We identified factors associated with unplanned rehospitalizations using multivariable logistic regression. Among 12 312 patients, 1326 (10.8%) had 1483 unplanned rehospitalizations within 30 days of the index event: 1028 (69.3%) were inpatient readmissions, and 455 (30.7%) were observation stays. The majority of unplanned rehospitalizations (72%) were for cardiovascular reasons. Variation in hospital rates of 30-day unplanned rehospitalization ranged from 5.4% to 20.0%, with a median of 10.7%. After multivariable modeling, the factors most strongly associated with unplanned rehospitalization were baseline quality of life and depression, followed by index hospital length of stay. Early unplanned rehospitalizations are common after acute myocardial infarction, and close to one third were classified as an observation stay. Predischarge and postdischarge assessments of overall, not just cardiovascular, health and strategies to optimize patient functional status may help to reduce unplanned rehospitalizations.

    To examine longitudinally the adaptive behavior patterns in fragile X syndrome. Caregivers of 275 children and adolescents with fragile X syndrome and 225 typically developing children and adolescents (2-18 years) were interviewed with the Vineland Adaptive Behavior Scales every 2 to 4 years as part of a prospective longitudinal study. Standard scores of adaptive behavior in people with fragile X syndrome are marked by a significant decline over time in all domains for males and in communication for females. Socialization skills are a relative strength as compared with the other domains for males with fragile X syndrome. Females with fragile X syndrome did not show a discernible pattern of developmental strengths and weaknesses. This is the first large-scale longitudinal study to show that the acquisition of adaptive behavior slows as individuals with fragile X syndrome age. It is imperative to ensure that assessments of adaptive behavior skills are part of intervention programs focusing on childhood and adolescence in this condition.

    Epilepsy is common in Rett syndrome, an X-linked dominant disorder caused by mutations in the MECP2 gene, and in Rett-related disorders, such as MECP2 duplication. However, neither the longitudinal course of epilepsy nor the patterns of seizure onset and remission have been described in Rett syndrome and related conditions. The present study summarizes the findings of the Rett syndrome Natural History study. Participants with clinical Rett syndrome and those with MECP2 mutations without the clinical syndrome were recruited through the Rett Natural History study from 2006 to 2015. Clinical details were collected, and cumulative lifetime prevalence of epilepsy was determined using the Kaplan-Meier estimator. Risk factors for epilepsy were assessed using Cox proportional hazards models. Of 1205 participants enrolled in the study, 922 had classic Rett syndrome, and 778 of these were followed longitudinally for 3939 person-years. The diagnosis of atypical Rett syndrome with a severe clinical phenotype was associated with higher prevalence of epilepsy than those with classic Rett syndrome. While point prevalence of active seizures ranged from 30% to 44%, the estimated cumulative lifetime prevalence of epilepsy using Kaplan-Meier approached 90%. Specific MECP2 mutations were not significantly associated with either seizure prevalence or seizure severity. In contrast, many clinical features were associated with seizure prevalence; frequency of hospitalizations, inability to walk, bradykinesia, scoliosis, gastrostomy feeding, age of seizure onset, and late age of diagnosis were independently associated with higher odds of an individual having epilepsy. Aggressive behaviour was associated with lower odds. Three distinct patterns of seizure prevalence emerged in classic Rett syndrome, including those who did not have seizures throughout the study, those who had frequent relapse and remission, and those who had relentless seizures. Although 248 of those with classic Rett

    Fragile X syndrome (FXS), due to mutations of the FMR1 gene, is the most common known inherited cause of developmental disability. The cognitive, behavioral, and neurological phenotypes observed in affected individuals can vary considerably, making it difficult to predict outcomes and determine the need for interventions. We sought to examine early structural brain growth as a potential marker for identification of clinically meaningful subgroups. Participants included 42 very young boys with FXS who completed a T1-weighted anatomical MRI and cognitive/behavioral assessment at two longitudinal time points, with mean ages of 2.89 y and 4.91 y. Topological data analysis (TDA), an unsupervised approach to multivariate pattern analysis, was applied to the longitudinal anatomical data to identify coherent but heretofore unknown subgroups. TDA revealed two large subgroups within the study population based solely on longitudinal MRI data. Post hoc comparisons of cognition, adaptive functioning, and autism severity scores between these groups demonstrated that one group was consistently higher functioning on all measures at both time points, with pronounced and significant unidirectional differences (P < 0.05 for time point 1 and/or time point 2 for each measure). These results support the existence of two longitudinally defined, neuroanatomically distinct, and clinically relevant phenotypes among boys with FXS. If confirmed by additional analyses, such information may be used to predict outcomes and guide design of targeted therapies. Furthermore, TDA of longitudinal anatomical MRI data may represent a useful method for reliably and objectively defining subtypes within other neuropsychiatric disorders.

    Full Text Available Triple A syndrome is an autosomal recessive disorder characterized by the triad of adrenocorticotropic hormone resistant adrenal insufficiency, achalasia, and alacrima. Our aim was to describe the neuropsychological characteristics and the cooccurring psychopathological and neurological disorders in an Italian male child suffering from Triple A syndrome at the time of admission (T0 and after one year of follow-up (T1. Many difficulties were observed in the motor domain, as well as in manual dexterity and static/dynamic balance domains of the motor task over time. In sharp contrast with previous literature reports on frequent mild cognitive dysfunction in patients with Triple A syndrome, our child did not show any mental retardation. By contrast, he showed an average IQ at T0 with a slight improvement at T1. To our knowledge, this report is the first describing neuropsychological profile and co-occurring psychopathological problems in a child with Triple A syndrome. Considering that the Triple A syndrome is a progressive disorder which can take years to develop the full-blown clinical picture, these patients require periodical medical controls. Moreover, assessment of neuropsychological and psychopathological features should be performed in patients with this disease, in order to underline the variability of this syndrome.

    According to the literature, children with Down syndrome (DS) have difficulties recognising facial expressions. Yet abilities to recognise emotional expressions are often assessed in tasks that imply comprehension of words for emotions. We investigated the development of these abilities in children with DS in a longitudinal study that did not involve lexical knowledge of emotions. Children with DS and nonspecific intellectual disability and typically developing children matched for developmental age (DA) were assessed once a year over 3 years. They were asked to recognise the facial expression of an emotion after hearing a vocalisation. In each annual session, children with DS were not significantly different from others at recognising emotions. Their abilities to discriminate basic emotions improved significantly and to a similar extent to those of other children. The findings indicate that children with DS develop emotion recognition abilities similarly to other children of the same DA.

    Observing another person performing a complex action accelerates the observer's acquisition of the same action and limits the time-consuming process of learning by trial and error. Observational learning makes an interesting and potentially important topic in the developmental domain, especially when disorders are considered. The implications of studies aimed at clarifying whether and how this form of learning is spared by pathology are manifold. We focused on a specific population with learning and intellectual disabilities, the individuals with Williams syndrome. The performance of twenty-eight individuals with Williams syndrome was compared with that of mental age- and gender-matched thirty-two typically developing children on tasks of learning of a visuo-motor sequence by observation or by trial and error. Regardless of the learning modality, acquiring the correct sequence involved three main phases: a detection phase, in which participants discovered the correct sequence and learned how to perform the task; an exercise phase, in which they reproduced the sequence until performance was error-free; an automatization phase, in which by repeating the error-free sequence they became accurate and speedy. Participants with Williams syndrome beneficiated of observational training (in which they observed an actor detecting the visuo-motor sequence) in the detection phase, while they performed worse than typically developing children in the exercise and automatization phases. Thus, by exploiting competencies learned by observation, individuals with Williams syndrome detected the visuo-motor sequence, putting into action the appropriate procedural strategies. Conversely, their impaired performances in the exercise phases appeared linked to impaired spatial working memory, while their deficits in automatization phases to deficits in processes increasing efficiency and speed of the response. Overall, observational experience was advantageous for acquiring competencies

    Le syndrome d'hypersensibilité médicamenteuse ou Drug Rash with Eosinophilia and Systemic Symptoms (DRESS) est une toxidermie rare mais sévère. Nous rapportons trois observations de DRESS syndromes secondaires à la prise de carbamazipine dans deux cas et de salazopyrine dans un cas. Le délai moyen entre la prise médicamenteuse et la survenue du DRESS syndrome était de six semaines. Le médicament incriminé était arrêté d'une façon définitive dans tous les cas. Une corticothérapie par voie générale était instaurée chez tous les patients devant l'atteinte hépatique sévère. L’évolution était favorable avec disparation des lésions cutanées et normalisation du bilan hépatique. Le diagnostic du syndrome DRESS doit être évoqué devant un tableau associant une éruption fébrile et des signes systémiques faisant suite à une prise médicamenteuse. La précocité du diagnostic est fondamentale pour l'arrêt définitif des médicaments suspects. Le traitement n'est pas bien codifié mais repose actuellement sur la corticothérapie générale.

    2012-01-01

    Prior research has indicated that pragmatics is an area of particular weakness for individuals with Williams syndrome (WS). To further address this aspect of the WS social phenotype, we used an individual differences approach to consider both cross-sectional and longitudinal relations among different pragmatic abilities for 14 children with WS, taking into account individual differences in non-verbal reasoning abilities. We also considered the relations between pragmatic abilities and expressive vocabulary ability. Participants were tested at two time points: as 4-year-olds during a 30-min play session with their mothers (Time 1) and an average of 5.87 years later during a one-on-one conversation with a familiar researcher (Time 2). Children’s intellectual and expressive vocabulary abilities were assessed at both time points. Results indicated that the ability to verbally contribute information beyond what was required in response to a question (ExtendQ) was significantly related to the ability to verbally contribute new information in the absence of a question (ExtendS) both at age 4 years and during primary school. At age 4, both the ability to pair verbalizations with eye contact in triadic interactions (secondary intersubjectivity) and expressive vocabulary ability were related to both ExtendQ and ExtendS. Finally, both ExtendQ and the ability to pair verbalizations with eye contact (intersubjectivity) at age 4 years predicted ExtendQ at age 9–12 years. The theoretical implications of our findings and the importance of early pragmatic language intervention for children who have WS are discussed. PMID:22719734

    In nerve compression syndromes restricted nerve sliding may lead to increased strain, possibly contributing to symptoms. Ultrasound was used to examine longitudinal median nerve sliding in 17 carpal tunnel syndrome patients and 19 controls during metacarpophalangeal joint movement. Longitudinal movement in the forearm averaged 2.62 mm in controls and was not significantly reduced in carpal tunnel syndrome (CTS) patients (mean=2.20 mm). In contrast, CTS patients had a 40% reduction in transverse nerve movement at the wrist on the most, compared to least, affected side and nerve areas were enlarged by 34%. Normal longitudinal sliding in the patients indicates that nerve strain is not increased and will not contribute to symptoms.

Cross-sectional analysis of multiple imputed data. Data from UK paediatric CFS/myalgic encephalomyelitis (CFS/ME) services compared with data collected at two time points in the Avon Longitudinal Study of Parents and Children (ALSPAC). 1685 adolescents who attended a CFS/ME specialist service between 2004 and 2014 and 13 978 adolescents aged approximately 13 years and 16 years participating in the ALSPAC study. Body mass index (BMI) (kg/m2), sex-specific and age-specific BMI Z-scores (relative to the International Obesity Task Force cut-offs) and prevalence of obesity (%). Adolescents who had attended specialist CFS/ME services had a higher prevalence of obesity (age 13 years: 9.28%; age 16 years: 16.43%) compared with both adolescents classified as CFS/ME in ALSPAC (age 13 years: 3.72%; age 16 years: 5.46%) and those non-CFS in ALSPAC (age 13 years: 4.18%; age 16 years: 4.46%). The increased odds of obesity in those who attended specialist services (relative to non-CFS in ALSPAC) was apparent at both 13 years (OR: 2.31 (1.54 to 3.48)) and 16 years, with a greater likelihood observed at 16 years (OR: 4.07 (2.04 to 8.11)). We observed an increased prevalence of obesity in adolescents who were affected severely enough to be referred to a specialist CFS/ME service. Further longitudinal research is required in order to identify the temporal relationship between the two conditions. Published by the BMJ Publishing Group Limited.

    Abstract Background: Metabolic syndrome is associated with higher risk for cardiovascular disease, sleep apnea, and nonalcoholic steatohepatitis, all common conditions in patients referred for bariatric surgery, and it may predict early postoperative complications. The objective of this study was to determine the prevalence of metabolic syndrome, defined using updated National Cholesterol Education Program criteria, in adults undergoing bariatric surgery and compare the prevalence of baseline co-morbid conditions and select operative and 30-day postoperative outcomes by metabolic syndrome status. Methods: Complete metabolic syndrome data were available for 2275 of 2458 participants enrolled in the Longitudinal Assessment of Bariatric Surgery-2 (LABS-2), an observational cohort study designed to evaluate long-term safety and efficacy of bariatric surgery in obese adults. Results: The prevalence of metabolic syndrome was 79.9%. Compared to those without metabolic syndrome, those with metabolic syndrome were significantly more likely to be men, to have a higher prevalence of diabetes and prior cardiac events, to have enlarged livers and higher median levels of liver enzymes, a history of sleep apnea, and a longer length of stay after surgery following laparoscopic Roux-en-Y gastric bypass (RYGB) and gastric sleeves but not open RYGB or laparoscopic adjustable gastric banding. Metabolic syndrome status was not significantly related to duration of surgery or rates of composite end points of intraoperative events and 30-day major adverse surgical outcomes. Conclusions: Nearly four in five participants undergoing bariatric surgery presented with metabolic syndrome. Establishing a diagnosis of metabolic syndrome in bariatric surgery patients may identify a high-risk patient profile, but does not in itself confer a higher risk for short-term adverse postsurgery outcomes.

    Children with Down syndrome are at risk for language difficulties, the nature of which is not well understood. This study compared the longitudinal predictors of language skills in children with Down syndrome with those in typically developing control children matched for initial level of nonverbal mental ability. An age cohort of children with Down syndrome (n=43) and 57 typically developing control children was assessed on measures of vocabulary, grammar, and verbal short-term memory three times at yearly intervals. Children with Down syndrome showed slower development on all measures than the typically developing controls. Longitudinal analyses showed moderate to high stability of language and verbal short-term memory skills. Our results confirm earlier evidence of pervasive language learning difficulties in this group and suggest that early language intervention should be given high priority.

    Previous studies have suggested that Alzheimer's disease (AD) causes an accelerated shortening of telomeres, the ends of chromosomes consisting of highly conserved TTAGGG repeats that, because of unidirectional 5'-3' DNA synthesis, lose end point material with each cell division. Our own previous work suggested that telomere length of T-lymphocytes might be a remarkably accurate biomarker for "mild cognitive impairment" in adults with Down syndrome (MCI-DS), a population at dramatically high risk for AD. To verify that the progression of cognitive and functional losses due to AD produced this observed telomere shortening, we have now examined sequential changes in telomere length in five individuals with Down syndrome (3F, 2M) as they transitioned from preclinical AD to MCI-DS (N = 4) or dementia (N = 1). As in our previous studies, we used PNA (peptide nucleic acid) probes for telomeres and the chromosome 2 centromere (as an "internal standard" expected to be unaffected by aging or dementia status), with samples from the same individuals now collected prior to and following development of MCI-DS or dementia. Consistent shortening of telomere length was observed over time. Further comparisons with our previous cross-sectional findings indicated that telomere lengths prior to clinical decline were similar to those of other adults with Down syndrome (DS) who have not experienced clinical decline while telomere lengths following transition to MCI-DS or dementia in the current study were comparable to those of other adults with DS who have developed MCI-DS or dementia. Taken together, findings indicate that telomere length has significant promise as a biomarker of clinical progression of AD for adults with DS, and further longitudinal studies of a larger sample of individuals with DS are clearly warranted to validate these findings and determine if and how factors affecting AD risk also influence these measures of telomere length. © 2015 Wiley Periodicals, Inc.

    To examine whether the use of Sasang constitutional (SC) types, such as Tae-yang (TY), Tae-eum (TE), So-yang (SY), and So-eum (SE) types, increases the accuracy of risk prediction for metabolic syndrome. From 2001 to 2014, 3529 individuals aged 40 to 69 years participated in a longitudinal prospective cohort. The Cox proportional hazard model was utilized to predict the risk of developing metabolic syndrome. During the 14 year follow-up, 1591 incident events of metabolic syndrome were observed. Individuals with TE type had higher body mass indexes and waist circumferences than individuals with SY and SE types. The risk of developing metabolic syndrome was the highest among individuals with the TE type, followed by the SY type and the SE type. When the prediction risk models for incident metabolic syndrome were compared, the area under the curve for the model using SC types was significantly increased to 0.8173. Significant predictors for incident metabolic syndrome were different according to the SC types. For individuals with the TE type, the significant predictors were age, sex, body mass index (BMI), education, smoking, drinking, fasting glucose level, high-density lipoprotein (HDL) cholesterol level, systolic and diastolic blood pressure, and triglyceride level. For Individuals with the SE type, the predictors were sex, smoking, fasting glucose, HDL cholesterol level, systolic and diastolic blood pressure, and triglyceride level, while the predictors in individuals with the SY type were age, sex, BMI, smoking, drinking, total cholesterol level, fasting glucose level, HDL cholesterol level, systolic and diastolic blood pressure, and triglyceride level. In this prospective cohort study among 3529 individuals, we observed that utilizing the SC types significantly increased the accuracy of the risk prediction for the development of metabolic syndrome.

    Telomere shortening was shown to parallel Alzheimer's disease (AD) associated dementia. By using a dual PNA Probe system we have developed a practical method for comparing telomere length in T-lymphocyte interphases from individuals with Down syndrome (DS) with and without "mild cognitive impairment" (MCI-DS) and demonstrated that telomere length can serve as a valid biomarker for the onset of MCI-DS in this high-risk population. To verify progressive cognitive decline we have now examined sequential changes in telomere length in 10 adults with DS (N = 4 Female, N = 6 Male) developing MCI-DS. Cases were selected blind to telomere length from a sample of adults with DS previously enrolled in a prospective longitudinal study at 18-month intervals with clinical and telomere assessments: (1) MCI-DS group data were collected approximately three years prior to development of MCI-DS; (2) 18 months later; (3) when MCI-DS was first observed. These telomere measures were compared to those from another 10 adults with DS matched by sex and approximate age but without indications of MCI-DS (Controls). PNA (peptide nucleic acid) probes for telomeres together with a chromosome two centromere probe were used. Findings indicated telomere shortening over time for both Cases and Controls. Group differences emerged by 18-months prior to recognition of MCI-DS onset and completely non-overlapping distributions of telomere measures were observed by the time of MCI-DS onset. This study adds to accumulating evidence of the value of telomere length, as an early biomarker of AD progression in adults with Down syndrome. © 2017 Wiley Periodicals, Inc.

    To evaluate the observed incidence of Down syndrome in twins compared with that expected based on maternal age-matched singletons, which is the current clinical approach. This was a retrospective review of California Prenatal Screening Program participants with expected delivery dates between July 1995 and December 2012. Cases confirmed prenatally or postnatally with a genetic imbalance leading to phenotypic Down syndrome (trisomy 21, mosaic trisomy 21, or translocations) were included. Pregnancies conceived with ovum donation and women older than 45 years were excluded. We compared the observed Down syndrome incidence per pregnancy for twins with expected incidence by extrapolating from singleton data and expected zygosity as is the current clinical approach. This extrapolation assumes that monozygotic pregnancies have equivalent Down syndrome risk per pregnancy relative to maternal age-matched singletons and dizygotic pregnancies have twice the risk of at least one affected fetus. Zygosity for affected cases was presumed to be monozygotic with Down syndrome concordance and dizygotic with Down syndrome discordance. Counts were compared using cumulative Poisson distributions. Of 77,279 twin pregnancies, 182 (0.2%) had at least one fetus with Down syndrome confirmed by karyotype. The ratio of observed-to-expected Down syndrome incidence per pregnancy was 33.6%, 75.2%, and 70.0% for monozygotic, dizygotic, and all twins, respectively (PDown syndrome incidence was seen for women aged 25 to 45 years with monozygotic pregnancies and overall for women aged 25 to 45 years with dizygotic pregnancies. The observed incidence of Down syndrome in twin pregnancies is lower than expected, most notably for monozygotic pregnancies and with increasing maternal age. Risk-based counseling can strongly affect women's choices regarding testing and management during pregnancy, so an understanding of the true Down syndrome risk in twin gestations is crucial.

    1990-07-01

    Full Text Available Forty patients with symptoms of neuro-vascular compression in the upper extremities were subjected to impedance plethysmographic study using Parulkar′s method. Two patients recorded decreased blood flow (BFI in supine position and were diagnosed as having partial occlusion at subclavian level. Sixteen of the patients recorded decreased BFI on 90 degrees abduction and hyper-abduction. Twelve of these patients had radiological evidence of anomalous cervicle ribs. In remaining four patients extrinsic impression on the subclavian artery due to fibrous deposits was confirmed by arteriography. Remaining 22 patients recorded normal impedance plethysmograms. Impedance plethysmography thus provided a non-invasive modality for confirmation of vascular compression in thoracic outlet syndrome.

    During normal movements or changes in position of the limbs, nerve structures must accommodate the resulting changes in length of the nerve path. In patients with carpal tunnel syndrome, we monitored electrophysiologically the longitudinal adjustment of the median nerve to positions of extreme flexion and extreme extension of the wrist and elbow, by measuring the differences induced in the latency of the sensory nerve action potential (SNAP) recorded in the forearm and upper arm. In patients, the latency difference was significantly shorter than in normal subjects (0.196 +/- 0.084 ms vs. 0.088 +/- 0.059 ms in the forearm, and 0.485 +/- 0.122 ms vs. 0.129 +/- 0.086 ms in the upper arm). These results indicate that the displacement of the source of the median nerve SNAP with movements of flexion and extension is limited in patients with carpal tunnel syndrome. Such an abnormality may partly underlie the pathophysiology of entrapment syndromes.

    Research findings on vocabulary development (1) in children with Down syndrome are inconsistent. This study aimed to analyse the developmental trend of vocabulary growth in children with Down syndrome and the relationships between vocabulary and chronological and developmental age. Children's vocabulary size was assessed by a parental report (the Italian version of the MacArthur-Bates Communicative Development Inventories [CDI]). A longitudinal study, involving 18 children with Down syndrome, and a cross-sectional study, involving 27 children with Down syndrome, were conducted. The variability in children's vocabulary size increased from a chronological age of 36 months. Both vocabulary size (from 36 months) and developmental level (from 42 months) were significant predictors of lexical outcomes at 48 months. A comparison with normative data showed that children with Down syndrome had a significantly lower vocabulary size than typically developing children at the same developmental age. Although there are similarities with vocabulary growth in typically developing children, lexical development in children with Down syndrome appears to lag behind their cognitive development.

    2012-06-01

    Full Text Available Although prior research has indicated that pragmatics is an area of particular weakness for individuals with Williams syndrome (WS, the relations among different pragmatic abilities and the relations between pragmatic ability and expressive vocabulary ability have yet to be addressed. In addition, analyses of the relations between the same type of pragmatic ability over time have not been reported. The present study was designed to address these questions. We considered the pragmatic language abilities of 14 children with WS at two time points: as 4-year-olds during a 30-minute play-session with their mothers (Time 1 and an average of 5.87 years later during a one-on-one conversation with a familiar researcher (Time 2. Children’s intellectual and expressive vocabulary abilities were assessed at both time points. Results indicated that the ability to verbally contribute information beyond what was required in response to a question was significantly related to the ability to verbally contribute new information in the absence of a question both at age 4 years and during primary school. At age 4, both the ability to pair verbalizations with eye contact (intersubjectivity and expressive vocabulary ability were related to the ability to verbally contribute information beyond what was expected within a social interaction. Finally, the ability to verbally contribute new information to a social interaction beyond what was required to answer a question and the ability to pair verbalizations with eye contact (intersubjectivity at age 4 years predicted the ability to verbally contribute new information beyond what was required to answer a question at age 9 – 12 years. The theoretical implications of our findings and the importance of early pragmatic language intervention for children who have WS are discussed.

  6. Demographic variables for wild Asian elephants using longitudinal observations.

    Directory of Open Access Journals (Sweden)

    Shermin de Silva

    Full Text Available Detailed demographic data on wild Asian elephants have been difficult to collect due to habitat characteristics of much of the species' remaining range. Such data, however, are critical for understanding and modeling population processes in this endangered species. We present data from six years of an ongoing study of Asian elephants (Elephas maximus in Uda Walawe National Park, Sri Lanka. This relatively undisturbed population numbering over one thousand elephants is individually monitored, providing cohort-based information on mortality and reproduction. Reproduction was seasonal, such that most births occurred during the long inter-monsoon dry season and peaked in May. During the study, the average age at first reproduction was 13.4 years and the 50(th percentile inter-birth interval was approximately 6 years. Birth sex ratios did not deviate significantly from parity. Fecundity was relatively stable throughout the observed reproductive life of an individual (ages 11-60, averaging between 0.13-0.17 female offspring per individual per year. Mortalities and injuries based on carcasses and disappearances showed that males were significantly more likely than females to be killed or injured through anthropogenic activity. Overall, however, most observed injuries did not appear to be fatal. This population exhibits higher fecundity and density relative to published estimates on other Asian elephant populations, possibly enhanced by present range constriction. Understanding the factors responsible for these demographic dynamics can shed insight on the future needs of this elephant population, with probable parallels to other populations in similar settings.

    2016-12-01

    Dysphonia is a potential long-term complication of preterm birth. Childhood voice disorders caused by vocal hyperfunction resolve with pubertal changes to the vocal mechanism in many cases. In extremely preterm children, whose voice quality is affected by supraglottic hyperfunction adapted secondary to underlying structural laryngeal pathology sustained during neonatal intubation, the prognosis is unknown. A pilot study was conducted to assess the incidence and severity of dysphonia in children born at dysphonia severity scores were significantly lower on repeat assessment, but no differences were observed in objective or quality of life scores. Individual variation was observed: the difference in CAPE-V scores ranged from -36 to + 1. No participant presented with normal voice quality on repeat assessment. Analysis of group data masked individual variability in this series. Mechanisms underlying such individual variation are currently unknown. These data suggest that dysphonia is persistent in extremely preterm children. Further investigation is warranted to elucidate the progression of voice disorders in extremely preterm children, to inform prognostic predictors and treatment decisions.

    Full Text Available Normal tension glaucoma (NTG is a disease associated with normal intraocular pressure (10 mmHg – 21 mmHg that may lead to irreversible blindness if misdiagnosed or left untreated over a period of time. The author observed a patient with NTG over a period of 5 years (from 2013 to 2017. The initial visual field analysis results (2014 showed mild visual field defects because of NTG at the start of the 5-year period. Although the patient was also diagnosed with hydrocephalus, a condition associated with optic nerve head damage, following years of noncompliance to treatment of NTG and follow-up eye examination schedules, the patient’s visual field defects were found to have progressed by the year 2017. It is therefore important for optometrists to apply due diligence when examining patients with NTG in order to expedite intervention and prevention of visual impairment and blindness.

    2006-12-01

    Full Text Available Abstract Background We report longitudinal changes in the metabolic syndrome (MetS in 2,458 participants from 480 families in the Family Heart Study. Participants were examined between 1994–96 (FHS-T1 and 2002–03 (FHS-T2, about 7.4 years apart. Additionally, the impact of medication on estimates of MetS prevalence, and associations of MetS with prevalent coronary heart disease (CHD and type 2 diabetes (T2D were studied. Methods Three definitions for MetS prevalence were considered. One represented the original (o National Cholesterol Education Program (NCEP MetS criteria. Two others considered the confounding of medications effects, respectively (m lipid medications constituted a categorical diagnostic criterion for lipids variables, and (c lipids and blood pressure variables were corrected with average clinical trials medications effects. Logistic regression of MetS on CHD and T2D, as well as the trend analysis of MetS by age, were performed. Results MetS increased from 17.1% in FHS-T1(o to 28.8% in FHS-T2(o; from 19.7% in FHS-T1(m to 42.5% in FHS-T2(m; and from 18.4% in FHS-T1(c to 33.6% in FHS-T2(c. While we observed adverse changes in all risk factors, the greatest increase was for waist circumference (25%. The percentages of MetS were about 2 to almost 3 times higher in ages 50 years and older than in younger ages. The odds of having prevalent CHD were about 2.5 times higher in the subjects classified with MetS than without. Conclusion MetS percentages increased noticeably longitudinally and cross-sectionally with older age. These conclusions were reached with and without considering medication use, but correcting risk factors for medications use affects the MetS prevalence estimates. As found in other studies, MetS was associated with increased odds for prevalent CHD.

    Longitudinal associations between triglycerides (TG) and other metabolic syndrome (MetS) components have rarely been reported. The purpose was to investigate the longitudinal association between TG and other MetS components with time. The longitudinal study was established in 2007 on individuals who attended health check-ups at Beijing Tongren Hospital and Beijing Xiaotangshan Hospital. Data used in this study was based on 7489 participants who had at least three health check-ups over a period of 5-year follow up. Joint model was used to explore longitudinal associations between TG and other MetS components after adjusted for age. There were positive correlations between TG and other MetS components except for high density lipoprotein (HDL), and the correlations increased with time. A negative correlation was displayed between TG and HDL, and the correlation also increased with time. Among all five pairs of TG and other MetS components, the marginal correlation between TG and body mass index (BMI) was the largest for both men and women. The marginal correlation between TG and fasting plasma glucose was the smallest for men, while the marginal correlation between TG and diastolic blood pressure was the smallest for women. The longitudinal association between TG and other MetS components increased with time. Among five pairs of TG and other MetS components, the longitudinal correlation between TG and BMI was the largest. It is important to closely monitor subjects with high levels of TG and BMI in health check-up population especially for women, because these two components are closely associated with development of hypertension, diabetes, cardiovascular disease and other metabolic diseases.

    To evaluate the course of sleep disordered breathing (SDB) in infants with Prader-Willi syndrome (PWS). Retrospective longitudinal observational study. Sleep laboratory at The Hospital for Sick Children, Toronto, Canada. Infants with PWS. The natural history of SDB in infants with PWS within 2 years from baseline assessment. We identified 28 (12 male) infants with PWS who had a baseline polysomnography (PSG) at a median age (interquartile (IQR)) of 0.9 (0.5, 1.1) years. The median central apnoea index (CAI) at baseline was 6.6 events/hour (IQR 2.6, 12.1). Of these, 15/28 (53%) infants with PWS were diagnosed with significant central sleep apnoea (CSA) (CAI≥5 events/hour). Median age (IQR) at follow-up PSG was 2.1 (1.5, 2.6) years. The median CAI improved from 6.6 to 2.3 events/hour (p<0.0001). Only four infants with PWS had persistent CSA at the time of the follow-up PSG. Furthermore, three infants with PWS were diagnosed with mild-to-moderate obstructive sleep apnoea (OSA) that has improved at follow-up studies whereas two patients with PWS with no evidence of OSA at baseline were diagnosed with severe OSA on the follow-up PSG requiring adenotonsillectomy. The overall median obstructive apnoea-hypopnoea index was similar between baseline and follow-up studies (0.6 and 0.8, respectively, p=0.91). CSA is prevalent in infants with PWS but usually improves with age. However, these patients continue to require ongoing PSG surveillance because some infants will have persistent CSA and others are at risk of developing OSA.

    The author has observed 64 films from M.P.D. syndrome cases taken in Dept. of Oral Radiology, the Infirmary of Den tal College, Seoul National University in 1974, and obtained the following results: 1. In M.P.D. syndrome, the ratio between the female and the male were 2:1. 2. The prevalent age was aged 20,30,10, and 40 in decreasing order. 3. The incidence was 21.8% in the left side, 29% in the right, and 21% was bilaterally, which show the right most frequent. 4. The roentgenograms revealed variable findings in each case, but there were not recognized any significant differences.

    Missing observations and covariate measurement error commonly arise in longitudinal data. However, existing methods for model selection in marginal regression analysis of longitudinal data fail to address the potential bias resulting from these issues. To tackle this problem, we propose a new model selection criterion, the Generalized Longitudinal Information Criterion, which is based on an approximately unbiased estimator for the expected quadratic error of a considered marginal model accounting for both data missingness and covariate measurement error. The simulation results reveal that the proposed method performs quite well in the presence of missing data and covariate measurement error. On the contrary, the naive procedures without taking care of such complexity in data may perform quite poorly. The proposed method is applied to data from the Taiwan Longitudinal Study on Aging to assess the relationship of depression with health and social status in the elderly, accommodating measurement error in the covariate as well as missing observations. © The Author 2015.

    Previous research examining the relationships among glycemic index, glycemic load, and the metabolic syndrome has resulted in inconsistent findings. The objective of this study was to examine whether glycemic index and glycemic load are associated with prevalent metabolic syndrome and its components after adjustment for cardiorespiratory fitness, an objective measure of physical activity habitus. Cross-sectional study. Women (n=1,775) and men (n=9,137) who completed a comprehensive medical examination between October 1987 and March 1999, including maximal treadmill exercise test and 3-day dietary records at the Cooper Clinic, Dallas, TX. Metabolic syndrome and its components, defined by the revised Adult Treatment Panel III criteria. Multiple logistic regression models were used to estimate sex-specific odds ratios and 95% confidence intervals to evaluate the associations among glycemic index, glycemic load, and prevalent metabolic syndrome and its components, while adjusting for potential confounding variables. Prevalence of metabolic syndrome was 24% in men and 9% in women. A positive association across quintiles of glycemic index and metabolic syndrome, elevated triglycerides, and low high-density lipoprotein cholesterol (HDL-C) in men was observed in the fully adjusted model (P for trendglycemic index was positively associated with large waist girth, low HDL-C, and elevated triglycerides (P for trendglycemic index, glycemic load, and metabolic syndrome that control for cardiorespiratory fitness are needed.

    Frailty is a clinical syndrome generally associated with a greater risk for adverse outcomes such as falls, disability, institutionalization, and death. Cognition and dementia have already been considered as components of frailty, but the role of frailty as a possible determinant of dementia, Alzheimer's disease (AD), and vascular dementia (VaD) has been poorly investigated. We estimated the predictive role of frailty syndrome on incident dementia and its subtypes in a nondemented, Italian, older population. We evaluated 2581 individuals recruited from the Italian Longitudinal Study on Aging sample population consisting of 5632 subjects aged 65 to 84 years and with a 3.9-year median follow-up. A phenotype of frailty according to a modified measurement of Cardiovascular Health Study criteria was operationalized. Dementia, AD, and VaD were classified using current published criteria. Over a 3.5-year follow-up, 65 of 2581 (2.5%) older subjects, 16 among 252 frail individuals (6.3%), of which 9 were affected by VaD (3.6%), developed overall dementia. In a proportional hazards model, frailty syndrome was associated with a significantly increased risk of overall dementia (adjusted hazard ratio: 1.85; 95% confidence interval: 1.01-3.40) and, in particular, VaD (adjusted hazard ratio: 2.68; 95% confidence interval: 1.16-7.17). The risk of AD or other types of dementia did not significantly change in frail individuals in comparison with subjects without frailty syndrome. In our large population-based sample, frailty syndrome was a short-term predictor of overall dementia and VaD. Copyright © 2013 The Alzheimer's Association. Published by Elsevier Inc.

    To analyse the correlates between the quality of life and chronic diseases and socio-demographic characteristics of patients in family medicine with a special emphasis on depression, panic syndrome, other anxiety syndrome and alcoholism. In a longitudinal study, the data set of 516 family practice attendees recruited from 60 family practices was analysed. Depression, panic syndrome, other anxiety syndrome and alcoholism were diagnosed using appropriate diagnostic interviews. Quality of life was assessed using the SF-12 questionnaire, measuring a mental health score and a physical health score. Data about the number of chronic somatic diseases were obtained from the patients' medical records. Physical health score was negatively associated with higher age (β = -0.25, p panic syndrome (β = -0.07, p panic syndrome and number of chronic somatic diseases as they are associated with poorer quality of life.

    Adults with Down syndrome (DS) represent an enriched population for the development of Alzheimer's disease (AD), which could aid the study of therapeutic interventions, and in turn, could benefit from discoveries made in other AD populations. 1) Understand the relationship between tau pathology and age, amyloid deposition, neurodegeneration (MRI and FDG PET), and cognitive and functional performance; 2) detect and differentiate AD-specific changes from DS-specific brain changes in longitudinal MRI. Twelve non-demented adults, ages 30 to 60, with DS were enrolled in the Down Syndrome Biomarker Initiative (DSBI), a 3-year, observational, cohort study to demonstrate the feasibility of conducting AD intervention/prevention trials in adults with DS. We collected imaging data with 18F-AV-1451 tau PET, AV-45 amyloid PET, FDG PET, and volumetric MRI, as well as cognitive and functional measures and additional laboratory measures. All amyloid negative subjects imaged were tau-negative. Among the amyloid positive subjects, three had tau in regions associated with Braak stage VI, two at stage V, and one at stage II. Amyloid and tau burden correlated with age. The MRI analysis produced two distinct volumetric patterns. The first differentiated DS from normal (NL) and AD, did not correlate with age or amyloid, and was longitudinally stable. The second pattern reflected AD-like atrophy and differentiated NL from AD. Tau PET and MRI atrophy correlated with several cognitive and functional measures. Tau accumulation is associated with amyloid positivity and age, as well as with progressive neurodegeneration measurable using FDG and MRI. Tau correlates with cognitive decline, as do AD-specific hypometabolism and atrophy.

    Nephrologists and kidney disease researchers are often interested in monitoring how patients' clinical and laboratory measures change over time, what factors may impact these changes, and how these changes may lead to differences in morbidity, mortality, and other outcomes. When longitudinal data with repeated measures over time in the same patients are available, there are a number of analytical approaches that could be employed to describe the trends and changes in these measures, and to explore the associations of these changes with outcomes. Researchers may choose a streamlined and simplified analytic approach to examine trajectories with subsequent outcomes such as estimating deltas (subtraction of the last observation from the first observation) or estimating per patient slopes with linear regression. Conversely, they could more fully address the data complexity by using a longitudinal mixed model to estimate change as a predictor or employ a joint model, which can simultaneously model the longitudinal effect and its impact on an outcome such as survival. In this review, we aim to assist nephrologists and clinical researchers by reviewing these approaches in modeling the association of longitudinal change in a marker with outcomes, while appropriately considering the data complexity. Namely, we will discuss the use of simplified approaches for creating predictor variables representing change in measurements including deltas and patient slopes, as well more sophisticated longitudinal models including joint models, which can be used in addition to simplified models based on the indications and objectives of the study as warranted. © The Author 2017.

  1. Observation of Longitudinal Spin Seebeck Effect with Various Transition Metal Films

    OpenAIRE

    Ishida, M.; Kirihara, A.; Someya, H.; Uchida, K.; Kohmoto, S.; Saitoh, E.; Murakami, T.

    2013-01-01

    We evaluated the thermoelectric properties of longitudinal spin Seebeck devices by using ten different transition metals (TMs). Both the intensity and sign of spin Seebeck coefficients were noticeably dependent on the degree of the inverse spin Hall effect and the resistivity of each TM film. Spin dependent behaviors were also observed under ferromagnetic resonance. These results indicate that the output of the spin Seebeck devices originates in the spin current.

    The purpose of this study was to compare angular change and translational motion from the medial longitudinal arch (MLA) and lateral longitudinal arch (LLA) during running between medial tibial stress syndrome (MTSS) and non-MTSS subjects. A total of 10 subjects volunteered, comprising 5 subjects with MTSS and 5 subjects without injury (non-MTSS) as the control group. All subjects performed the test movement that simulated running. Fluoroscopic imaging was used to investigate bone movement during landing in running. Sagittal motion was defined as the angular change and translational motion of the arch. A Mann-Whitney U-test was performed to determine the differences in the measured values between the MTSS and non-MTSS groups. The magnitude of angular change for the MLA and LLA was significantly greater for subjects with MTSS than for control subjects. Translational motion of the MLA and LLA of the MTSS group was also significantly greater than that of the non-MTSS group (all p risk factor for the development of MTSS in these subjects.

    Advances in the care of patients with fragile X syndrome (FXS) have been hampered by lack of data. This deficiency has produced fragmentary knowledge regarding the natural history of this condition, healthcare needs, and the effects of the disease on caregivers. To remedy this deficiency, the Fragile X Clinic and Research Consortium was established to facilitate research. Through a collective effort, the Fragile X Clinic and Research Consortium developed the Fragile X Online Registry With Accessible Research Database (FORWARD) to facilitate multisite data collection. This report describes FORWARD and the way it can be used to improve health and quality of life of FXS patients and their relatives and caregivers. FORWARD collects demographic information on individuals with FXS and their family members (affected and unaffected) through a 1-time registry form. The longitudinal database collects clinician- and parent-reported data on individuals diagnosed with FXS, focused on those who are 0 to 24 years of age, although individuals of any age can participate. The registry includes >2300 registrants (data collected September 7, 2009 to August 31, 2014). The longitudinal database includes data on 713 individuals diagnosed with FXS (data collected September 7, 2012 to August 31, 2014). Longitudinal data continue to be collected on enrolled patients along with baseline data on new patients. FORWARD represents the largest resource of clinical and demographic data for the FXS population in the United States. These data can be used to advance our understanding of FXS: the impact of cooccurring conditions, the impact on the day-to-day lives of individuals living with FXS and their families, and short-term and long-term outcomes.

    Full Text Available Abstract Background We provided clinical and electrical descriptions of the piriformis syndrome, contributing to better understanding of the pathogenesis and further diagnostic criteria. Methods Between 3550 patients complaining of sciatica, we concluded 26 cases of piriformis syndrome, 15 females, 11 males, mean age 35.37 year-old. We operated 9 patients, 2 to 19 years after the onset of symptoms, 5 had piriformis steroids injection. A dorsolumbar MRI were performed in all cases and a pelvic MRI in 7 patients. The electro-diagnostic test was performed in 13 cases, between them the H reflex of the peroneal nerve was tested 7 times. Results After a followup 1 to 11 years, for the 17 non operated patients, 3 patients responded to conservative treatment. 6 of the operated had an excellent result, 2 residual minor pain and one failed. 3 new anatomical observations were described with atypical compression of the sciatic nerve by the piriformis muscle. Conclusion While the H reflex test of the tibial nerve did not give common satisfaction in the literature for diagnosis, the H reflex of the peroneal nerve should be given more importance, because it demonstrated in our study more specific sign, with six clinical criteria it contributed to improve the method of diagnosis. The cause of this particular syndrome does not only depend on the relation sciatic nerve-piriformis muscle, but the environmental conditions should be considered with the series of the anatomical anomalies to explain the real cause of this pain.

    We report two patients with velo-cardio-facial syndrome (VCFS) who were admitted to our pediatric endocrinology clinic because of short stature and followed longitudinally until attainment of final height. Both patients followed a growth pattern consistent with constitutional delay of puberty with normal and near normal final height. Case 2 also had partial growth hormone (GH) deficiency and severe short stature (height SDS -3.4 SDS), but showed spontaneous catch-up and ended up with a final height of -2 SDS. These cases suggest that short stature in children with VCFS is due to a pattern of growth similar to that observed in constitutional delay of growth and puberty.

    To determine the conversion risk and predictors for depression in women with polycystic ovary syndrome. Prospective longitudinal study. University practice. Subjects with polycystic ovary syndrome who had participated in a previous study. None. The Primary Care Evaluation of Mental Disorders Patient Health Questionnaire was used to diagnose major depressive disorder and other depressive syndromes, anxiety syndromes, and binge eating disorder. Subjects completed a questionnaire on knowledge about polycystic ovary syndrome and treatment satisfaction. A total of 60 of 103 subjects responded to the second survey. Mean time between the two surveys was 22 months (range 12-26 months). The overall prevalence of depression was 40% (24/60). Of these, 10 women screened positive for major depressive disorder or other depressive syndromes and 14 were receiving antidepressant medications. There were 11 new cases identified in the second survey (19% conversion). Total subjects with mood disorders in this study were 34/60 (56.6%), including 11.6% with anxiety syndromes and 23.3% with binge eating disorder. Difficulties with menstrual function, fertility, and body image (weight, hirsutism, acne) were not significantly different in women with and without depression. There is a significant risk for mood disorders (defined by the Diagnostic and Statistical Manual of Mental Disorders-IV) in women with polycystic ovary syndrome. This finding together with a high conversion risk for depression over a 1- to 2-year period underscores the importance of routine screening and aggressive treatment of mental health disorders in this population.

    Cardiovascular diseases and diabetes mellitus type II (DM II) are both major health problems. A large risk factor for these diseases is the presence of the metabolic syndrome. It is known that the risk of DM II can be decreased by coffee consumption. Therefore, we examined the association between coffee consumption and the components of the metabolic syndrome. Prospective data from the Amsterdam Growth and Health Longitudinal Study (AGAHLS) is used to analyse the associations between coffee consumption (averaged over a period from 27 till 42 years) and the components of the metabolic syndrome (at the age of 42 years). This was done by linear regression analyses and associations were adjusted for physical activity, energy intake, alcohol consumption and smoking behaviour. The results showed that moderate and high (>2 cups/day) coffee consumption was significantly associated with lower HDL in women. For men, coffee consumption was not associated with any of the components of the metabolic syndrome.

    Gonadal dysfunction and infertility are major endocrinological late effects among childhood cancer survivors. Chemotherapy and radiation have gonadotoxic effects and diminish the ovarian reserve. The serum concentration of anti-Müllerian hormone (AMH) is a useful marker of ovarian reserve in survivors. We conducted a longitudinal study to investigate the variations of AMH in evaluating the acute and chronic effects of cancer therapy on the ovary. Three young female patients with different hematological diseases were registered, and their medical records were reviewed. Patient 1 with myelodysplastic syndrome received reduced-intensity hematopoietic stem cell transplantation (HSCT) at 10 yr of age. Breast development and menarche occurred spontaneously after HSCT; however, AMH level became undetectable and gonadotropin did not increase. Patient 2 with acute lymphoblastic leukemia had been receiving chemotherapy since 11 yr of age. AMH level became undetectable but increased after chemotherapy and was associated with regular menstruation. Patient 3 with acute myeloid leukemia received chemotherapy at 13 yr of age and myeloablative HSCT at 14 yr of age. AMH level became undetectable after HSCT, and the patient developed amenorrhea. These different patterns in the recovery phase demonstrated that the AMH level immediately after the end of cancer therapy is inappropriate for the evaluation of the ovarian reserve.

    Usher syndrome (USH) is a genetically heterogeneous deafness-blindness syndrome, divided into three clinical subtypes: USH1, USH2 and USH3. Mutations in 21 out of 26 investigated Danish unrelated individuals with USH were identified, using a combination of molecular diagnostic methods. Before Next Generation Sequencing (NGS) became available mutations in nine individuals (1 USH1, 7 USH2, 1 USH3) were identified by Sanger sequencing of USH1C,USH2A or CLRN1 or by Arrayed Primer EXtension (APEX) method. Mutations in 12 individuals (7 USH1, 5 USH2) were found by targeted NGS of ten known USH genes. Five novel pathogenic variants were identified. We combined our data with previously published, and obtained an overview of the USH mutation spectrum in Denmark, including 100 unrelated individuals; 32 with USH1, 67 with USH2, and 1 with USH3. Macular edema was observed in 44 of 117 individuals. Olfactory function was tested in 12 individuals and found to be within normal range in all. Mutations that lead to USH1 were predominantly identified in MYO7A (75%), whereas all mutations in USH2 cases were identified in USH2A. The MYO7A mutation c.93C>A, p.(Cys31*) accounted for 33% of all USH1 mutations and the USH2A c.2299delG, p.(Glu767Serfs*21) variant accounted for 45% of all USH2 mutations in the Danish cohort.

    Laser-plasma accelerators can produce high quality electron beams, up to giga-electronvolts in energy, from a centimeter scale device. The properties of the electron beams and the accelerator stability are largely determined by the injection stage of electrons into the accelerator. The simplest mechanism of injection is self-injection, in which the wakefield is strong enough to trap cold plasma electrons into the laser wake. The main drawback of this method is its lack of shot-to-shot stability. Here we present experimental and numerical results that demonstrate the existence of two different self-injection mechanisms. Transverse self-injection is shown to lead to low stability and poor quality electron beams, because of a strong dependence on the intensity profile of the laser pulse. In contrast, longitudinal injection, which is unambiguously observed for the first time, is shown to lead to much more stable acceleration and higher quality electron beams.

  12. The Fine Structure of the Longitudinal Machine Impedance Observed with Single Bunches

    1998-01-01

    Using a beam spectrum measurement the detailed structure of the CERN SPS longitudinal machine impedance has been observed over a wide frequency range. Single high intensity proton bunches were injected into the machine with RF off. The spectrum of the unstable bunch modes, produced by the different resonant impedances in the ring, was measured during slow debunching. The maximum mode amplitude as a function of frequency was recorded for many injected bunches. The central frequency of each bunch mode is close to the resonant frequency of the impedance and the width depends upon the bunch length. Using sufficiently long bunches allowed the machine impedance to be seen in detail in the frequency range 100MHz to 4GHz. The low frequency of this range is defined by the initial stable bunch spectrum, and the high frequency by the vacuum chamber cut-off frequency. The dominant peaks in the spectrum have been identified with different impedance sources in the machine - some previously unknown.

    To assess the longitudinal change in autonomic nervous system (ANS) activity during pregnancy and the association between anxiety during pregnancy and ANS activity. Pregnant Japanese women with a singleton fetus and normal pregnancy were recruited (n=65). ANS activity and anxiety were measured using a self-rating questionnaire at approximately 20, 30, and 36weeks of gestation. Very low (VLF) and high (HF) frequency bands of heart rate variability spectrums were used. Anxiety was assessed using the Japanese version of the State-Trait Anxiety Inventory. A score of 45 or more on trait-anxiety and the other represent the trait-anxiety group and the non- trait-anxiety group, respectively. The state-anxiety group and the non-state-anxiety group were defined in the same manner. Longitudinal observation of individual pregnant women indicated the significant increasing trend (p=0.002) of VLF power and the significant decreasing trend (p<0.001) of HF power during 20 to 36 gestation weeks. Compared with the non-trait-anxiety group, the trait-anxiety group had significantly lower VLF values at 20 gestational weeks (p=0.033) and had significantly lower HF values at 30 and 36 gestational weeks (p=0.015 and p=0.044, respectively). The increasing rate of VLF from 20 to 36 gestational weeks was higher among the trait-anxiety group. The same associations were observed between the state-anxiety and non-state-anxiety groups at 20 gestational weeks. Anxiety during pregnancy decreased heart rate variability. Anxiety in second trimester pregnancy promoted a subsequent increase in sympathetic activity. Copyright © 2017 Elsevier Inc. All rights reserved.

    Brain-derived neurotrophic factor (BDNF) plays a crucial role in neurodevelopment, synaptic plasticity and neuronal function and survival. Serum and plasma BDNF levels are moderately, but consistently, decreased in patients with schizophrenia (SCZ) compared with healthy controls. There is a lack of knowledge, however, on the temporal manifestation of this decline. Clinical, illness course and treatment factors might influence the variation of BDNF serum levels in patients with psychosis. In this context, we propose a longitudinal study of a cohort of SCZ and schizophrenic and schizoaffective disorder (SAD) Sardinian patients with the aim of disentangling the relationship between peripheral BDNF serum levels and changes of psychopathology, cognition and drug treatments. Longitudinal assessment of BDNF in Sardinian psychotic patients (LABSP) is a 24-month observational prospective cohort study. Patients with SAD will be recruited at the Psychiatry Research Unit of the Department of Medical Science and Public Health, University of Cagliari and University of Cagliari Health Agency, Cagliari, Italy. We will collect BDNF serum levels as well as sociodemographic, psychopathological and neurocognitive measures. Structured, semistructured and self-rating assessment tools, such as the Positive and Negative Syndrome Scale for psychopathological measures and the Brief Assessment of Cognition in Schizophrenia for cognitive function, will be used. This study protocol was approved by the University of Cagliari Health Agency Ethics Committee (NP2016/5491). The study will be conducted in accordance with the principles of good clinical practice, in the Declaration of Helsinki in compliance with the regulations. Participation will be voluntary and written informed consent will be obtained for each participant upon entry into the study. We plan to disseminate the results of our study through conference presentations and publication in international peer-reviewed journals. Access to

    Although geriatric syndromes have been studied extensively, their interactions with one another and their accumulated effects on life expectancy are less frequently discussed. This study examined whether geriatric syndromes and their cumulative effects are associated with risks of mortality in community-dwelling older adults. Data were collected from the Taiwan Longitudinal Study in Aging in 2003, and the participant survival status was followed until December 31, 2007. A total of 2744 participants aged ≥65 years were included in this retrospective cohort study; 634 died during follow-up. Demographic factors, comorbidities, health behaviors, and geriatric syndromes, including underweight, falls, functional impairment, depressive condition, and cognitive impairment, were assessed. Cox proportional hazard regression analysis was used to estimate the hazard ratios (HRs) and 95% confidence intervals (CIs) for the probability of survival according to the cumulative number of geriatric syndromes. The prevalence of geriatric syndromes increased with age. Mortality was significantly associated with age ≥75 years; male sex; ≤6 years of education; history of stroke, malignancy; smoking; not drinking alcohol; and not exercising regularly. Geriatric syndromes, such as underweight, functional disability, and depressive condition, contributed to the risk of mortality. The accumulative model of geriatric syndromes also predicted higher risks of mortality (N = 1, HR 1.50, 95% CI 1.19-1.89; N = 2, HR 1.69, 95% CI 1.25-2.29; N ≥ 3, HR 2.43, 95% CI 1.62-3.66). Community-dwelling older adults who were male, illiterate, receiving institutional care, underweight, experiencing a depressive condition, functionally impaired, and engaging in poor health behavior were more likely to have a higher risk of mortality. The identification of geriatric syndromes might help to improve comprehensive care for community-dwelling older adults. Copyright © 2016 AMDA – The Society for

    By the age of 40, virtually all patients with Down syndrome (DS) have neuropathological changes characteristic of Alzheimer's disease (AD). The aim of our study was to investigate whether the levels of superoxide dismutase enzymes (SOD), glutathione peroxidase (GPx), or their ratio could predict cognitive decline in people with DS over a 4-year period. Thirty-two adults with DS participated in a longitudinal study with SOD and GPx assays at baseline. Informants rated their functional ability and memory function at baseline and at 4 years follow-up. The more able adults with DS also completed assessments of language skills and memory, at two different time points 4 years apart. Twenty-six individuals with DS completed assessments of memory (Modified Memory Object Task, MOMT), adaptive behavior (ABAS), and receptive vocabulary (British Picture vocabulary, BPVS) at both time-points. SOD positively correlated with change on the MOMT score (r = 0.578, p = 0.015). There were no significant correlations between GPx level or SOD/GPx ratio and temporal changes in ABAS, BPVS, or MOMT scores. Our results suggest that SOD predicts memory decline over time and that these antioxidant enzymes could be a potential target for prevention of memory deterioration in adults with DS. Further research is required to test whether supplements which improve SOD function can also prevent cognitive decline. These findings may also have implications for prevention of cognitive decline in other groups which are at high risk of developing dementia, such as adults with familial AD or mild cognitive impairment.

    To examine the effect of early clinical and demographic factors on occupational outcome, return to work or awarded permanent disability pension in young patients with chronic fatigue syndrome (CFS). Longitudinal cohort study. A written self-management programme including a description of active coping strategies for daily life was provided. Patients with CFS after mononucleosis were evaluated at Department of Neurology, Haukeland University Hospital during 1996-2006 (contact 1). In 2009 self-report questionnaires were sent to all patients (contact 2). Primary measure was employment status at contact 2. Secondary measures included clinical symptoms, and Fatigue Severity Scale (FSS) scores on both contacts, and Work and Social Adjustment Scale (WSAS) at contact 2. Of 111 patients at contact 1, 92 (83%) patients returned the questionnaire at contact 2. Mean disease duration at contact 1 was 4.7 years and at contact 2 11.4 years. At contact 1, 9 (10%) were part-time or full-time employed. At contact 2, 49 (55%) were part-time or full-time employed. Logical regression analysis showed that FSS≥5 at contact 2 was associated with depression, arthralgia and long disease duration (all at contact 1). About half of younger patients with CFS with long-term incapacity for work experienced marked improvement including full-time or part-time employment showing better outcomes than expected. Risk factors for transition to permanent disability were depression, arthralgia and disease duration. Published by the BMJ Publishing Group Limited.

  18. An Observation of a Transverse to Longitudinal Emittance Exchange at the Fermilab A0 Photoinjector

    Energy Technology Data Exchange (ETDEWEB)

    An experimental program to perform a proof of principle of transverse to longitudinal emittance exchange (ϵxin ↔ ϵzout and ϵxin ↔ ϵzout) has been developed at the Fermilab A0 Photoinjector. A new beamline, including two magnetic dogleg channels and a TM110 deflecting mode radio frequency cavity, were constructed for the emittance exchange experiment. The first priority was a measurement of the Emittance Exchange beamline transport matrix. The method of difference orbits was used to measure the transport matrix. Through varying individual beam input vector elements, such as xin, x'in, yin, y'in, zin, or δin, and measuring the changes in all of the beam output vector's elements, xout, x'out, yout, y'out, zout, δout, the full 6 x 6 transport matrix was measured. The measured emittance exchange transport matrix was in overall good agreement with our calculated transport matrix. A direct observation of an emittance exchange was performed by measuring the electron beam's characteristics before and after the emittance exchange beamline. Operating with a 14.3 MeV, 250pC electron bunch, ϵzin of 21.1 ± 1.5 mm • mrad was observed to be exchanged with ϵxout of 20.8 ± 2.00 mm • mrad. Diagnostic limitations in the ϵzout measurement did not account for an energy-time correlation, thus potentially returning values larger than the actual longitudinal emittance. The ϵxin of 4.67 ± 0.22 mm • mrad was observed to be exchanged with ϵzout of 7.06 ± 0.43 mm • mrad. The apparent ϵzoutgrowth is consistent with calculated values in which the correlation term is neglected.

    Given borderline personality disorder's (BPD) relation with interpersonal dysfunction, there is substantial interest in understanding BPD's effect on marriage. The current study used data from a community sample of 172 newlywed couples to examine spouses' BPD symptoms in relation to their observed communication, partner BPD symptoms, 4-year marital quality trajectories, and 10-year divorce rates. BPD symptoms were correlated cross-sectionally with more negative skills during observational problem-solving and social support tasks, and spouses reporting more BPD symptoms were married to partners reporting more BPD symptoms. Longitudinally, hierarchical linear modeling of newlyweds' 4-year marital trajectories indicated that BPD symptoms predicted the intercept of marital quality for spouses and their partners, reflecting lower levels of marital satisfaction and higher levels of marital problems. BPD symptoms did not predict 10-year divorce rates. These findings highlight the chronic relationship impairment associated with BPD symptoms, indicate that distress begins early in marriage, and suggest that partners with higher levels of BPD symptoms remain in more troubled marriages.

    Background: Binge-eating disorder may represent a risk factor for the metabolic syndrome. Objective: The objective was to assess longitudinally the relation between binge-eating disorder and components of the metabolic syndrome. Design: At 2.5 and 5 y of follow-up, 134 individuals with binge-eating disorder and 134 individuals with no history of eating disorders, who were frequency-matched for age, sex, and baseline body mass index (BMI), were interviewed during the follow-up interval regarding new diagnoses of 3 metabolic syndrome components: hypertension, dyslipidemia, and type 2 diabetes. Results: A comparison of individuals with and without a binge-eating disorder in analyses adjusted for age, sex, baseline BMI, and interval BMI change had hazard ratios (95% CIs) for reporting new diagnoses of metabolic syndrome components of 2.2 (1.2, 4.2; P = 0.023) for dyslipidemia, 1.5 (0.76, 2.9; P = 0.33) for hypertension, 1.6 (0.77, 3.9; P = 0.29) for type 2 diabetes, 1.7 (1.1, 2.6; P = 0.023) for any component, and 2.4 (1.1, 5.7; P = 0.038) for ≥2 components. Conclusion: Binge-eating disorder may confer a risk of components of the metabolic syndrome over and above the risk attributable to obesity alone.

    Study Objectives: Previous case reports of intravenous immunoglobulins (IVIg) in pediatric narcolepsy have shown contradictory results. Methods: This was a nonrandomized, open-label, controlled, longitudinal observational study of IVIg use in pediatric narcolepsy with retrospective data collection from medical files obtained from a single pediatric national reference center for the treatment of narcolepsy in France. Of 56 consecutively referred patients with narcolepsy, 24 received IVIg (3 infusions administered at 1-mo intervals) in addition to standard care (psychostimulants and/or anticataplectic agents), and 32 continued on standard care alone (controls). Results: For two patients in each group, medical files were unavailable. Of the 22 IVIg patients, all had cerebrospinal fluid (CSF) hypocretin ≤ 110 pg/mL and were HLA-DQB1*06:02 positive. Of the 30 control patients, 29 were HLA-DQB1*06:02 positive and of those with available CSF measurements, all 12 had hypocretin ≤ 110 pg/mL. Compared with control patients, IVIg patients had shorter disease duration, shorter latency to sleep onset, and more had received H1N1 vaccination. Mean (standard deviation) follow-up length was 2.4 (1.1) y in the IVIg group and 3.9 (1.7) y in controls. In multivariate-adjusted linear mixed-effects analyses of change from baseline in Ullanlinna Narcolepsy Scale (UNS) scores, high baseline UNS, but not IVIg treatment, was associated with a reduction in narcolepsy symptoms. On time-to-event analysis, among patients with high baseline UNS scores, control patients achieved a UNS score narcolepsy symptoms were not significantly reduced by IVIg. However, in patients with high baseline symptoms, a subset of IVIg-treated patients achieved remission more rapidly than control patients.

    To identify baseline risk factors associated with hemiplegic shoulder pain during the first 6 months after a stroke and to investigate changes in these risk factors over time. Longitudinal observational study. A total of 94 patients with first-ever unilateral stroke lesion within 1 month after stroke. Clinical, radiological and sonographic evaluations were performed at baseline. Hemiplegic shoulder pain was assessed at 1, 3 and 6 months post-stroke. Associations between baseline factors and hemiplegic shoulder pain during the first 6 months and hemiplegic shoulder pain at 1, 3 and 6 months poststroke were analysed. Poor arm motor function, indicated by a poor National Institutes of Health Stroke Scale item 5 score (odds ratio (OR) = 3.0; 95% confidence interval (CI) = 1.1-7.7) and the presence of supraspinatus tendon pathology (OR = 4.2; 95% CI = 1.4-12.9), were associated with hemiplegic shoulder pain. While patients with adhesive capsulitis, glenohumeral subluxation, or long head of biceps tendon effusion showed a higher prevalence of hemiplegic shoulder pain at 1 month after stroke, those with supraspinatus tendon pathology showed a higher prevalence at 3 and 6 months. Patients at high risk of hemiplegic shoulder pain with severe arm paralysis and supraspinatus tendon pathology require more careful attention during the rehabilitation period.

    Calculating the longitudinal extension of the average attributable fraction (LE-AAF) for many risk factors (RFs) requires a two-stage computational process using only those combinations of RFs observed in the dataset. We first screen candidates RFs in a Cox Model, and assuming piecewise constant hazards, use pooled logistic regression to model the probability of death as a function of combinations of selected RFs. We average the iterative differencing of the attributable fractions calculated for all overlapping subsets of co-occurring RFs to obtain a LE-AAF for each RF that is additive and symmetrical. We illustrate by partitioning the additive proportions of death from 10 different groupings of acute and chronic diseases, on a national sample of older persons from the US (Medicare Beneficiary Survey) over a 4-year period and compare with results reported by the National Center for Healthcare Statistics. We conclude that careful screening of RFs with analysis restricted to extant combinations greatly reduces computational burden. LE-AAF accounted for a cumulative total of 66% of the deaths in our sample, compared with the 83% accounted for by the National Center for Healthcare Statistics.

    In acquired immunodeficiency syndrome (AIDS) studies it is quite common to observe viral load measurements collected irregularly over time. Moreover, these measurements can be subjected to some upper and/or lower detection limits depending on the quantification assays. A complication arises when these continuous repeated measures have a heavy-tailed behavior. For such data structures, we propose a robust structure for a censored linear model based on the multivariate Student's t-distribution. To compensate for the autocorrelation existing among irregularly observed measures, a damped exponential correlation structure is employed. An efficient expectation maximization type algorithm is developed for computing the maximum likelihood estimates, obtaining as a by-product the standard errors of the fixed effects and the log-likelihood function. The proposed algorithm uses closed-form expressions at the E-step that rely on formulas for the mean and variance of a truncated multivariate Student's t-distribution. The methodology is illustrated through an application to an Human Immunodeficiency Virus-AIDS (HIV-AIDS) study and several simulation studies.

    Hemiconvulsion-hemiplegia syndrome (HHS) is a rare severe epilepsy of infancy consisting of unilateral convulsive status epilepticus immediately followed by transient or lasting ipsilateral hemiplegia. HHS may occur either in patients with previous brain pathology or without any identified cause, so-called 'idiopathic HHS'. We retrospectively analysed clinical and MRI longitudinal findings of a series of 10 patients (six females, four males) presenting with HHS. Age at the study inclusion ranged from 2 years 6 months to 15 years (mean of 5 y 10 mo, median 4 y 2 mo). After defining magnetic resonance imaging (MRI) features as 'typical', i.e. strictly unilateral involvement, and 'atypical', i.e. bilateral, we compared clinical data from both groups. Cognitive level was assessed using Brunet-Lézine or Wechsler scales. HHS occurred at a mean age of 20.5 months (range 8-48 mo). In all cases, status epilepticus lasted for more than 1 hour and was characterised by unilateral clonic seizures followed by ipsilateral hemiplegia (persistent in five patients). Two patients in this series died: the first from multi-organ failure 2 weeks after the status epilepticus and the other from a second episode of ipsilateral intractable febrile status epilepticus 3 years after the first episode. Early MRI (days 1-7 from status epilepticus) showed hemispheric cytotoxic oedema in all, extending to the contralateral side for one. T2 hyperintensity in the basal ganglia was disclosed in 70% of patients and in the hippocampus in 60%. After 1 month (in intermediate and chronic phases), all surviving patients but one showed hemispheric cortical atrophy corresponding to the regions involved during the early stage. Comparing clinical features of patients presenting with 'typical' features, to those with 'atypical' findings, the second group presented psychomotor delay before status epilepticus. This series underlines the major value of early MRI for the prompt diagnosis of HHS, and shows that

    Influences of the Big Five personality traits on the treatment response and longitudinal course of depression in patients with acute coronary syndrome: A randomised controlled trial. This naturalistic observational study initially recruited 1152 ACS patients; 685 patients completed personality assessments at baseline, of whom 630 were followed-up one year later. Of the 294 patients with depression, 207 participated in a 24-week double blind trial of escitalopram or placebo. The remaining 87 patients who received medical treatment only and the 391 who had not depression were also followed in a one year naturalistic observational study. The Big five personality traits were assessed using the Big Five Inventory. The influences of personality on the Hamilton Depression Rating Scale score changes were analysed using a mixed-model repeated-measures analysis of covariance. A Cluster analysis identified two personality types: resilient and vulnerable. The vulnerable personality type was characterized by lower extraversion, agreeableness, and conscientiousness - but higher neuroticism - than the resilient type. This personality type was independently associated with a poorer outcome of depression in ACS patients during the 24-week treatment period and the one year longitudinal follow-up period compared to the resilient personality type, irrespective of treatment allocation. Recruitment from a single institution may limit generalisability. Personality traits were investigated 12-weeks after ACS; thus, the responses may have been influenced by the prior receipt of escitalopram. Personality types influences the treatment outcome and longitudinal course of depression in ACS patients independent of antidepressant treatment. Copyright © 2016 Elsevier B.V. All rights reserved.

    Physical exercise recommendations become particularly effective when embedded into medical rehabilitation. However, little is known about long-term behaviour maintenance and its effect on sickness absence and subjective employability. The current longitudinal observational study investigated self-reported physical exercise, sickness absence and subjective employability over a period of 8 years. A total of 601 (T0) outpatients (mean age 45.14 years; standard deviation 10.73 years, age range 18-65 years) with different orthopaedic disorders were recruited during their 3-week medical rehabilitation in Germany. Of these, 61.7% (n = 371) were female. Follow-ups were carried out at 6 months (T1, n = 495), 12 months (T2, n = 340), 3 years (T3, n = 296) and 8 years (T4, n = 142) after baseline. Patient characteristics, exercise status, social-cognitive variables, sickness absence and subjective employability were obtained via self-report questionnaires. SPSS hierarchical regression models were used for data analysis, controlling for baseline measures and sociodemographic variables. Physical exercise status 6 months after rehabilitation treatment (T1) predicted sickness absence at 12 months (T2). Inactive people were 3.28 times more likely to be on sick leave at T2. In addition, physical exercise at T1 predicted subjective employability 12 months (T2) and 3 years (T3) later. Those who met the recommendations to be physically active for at least 40 min a week were more likely to feel able to work. Exercise appears to play an important role in reducing sickness absence and subjective employability and should be promoted within and after rehabilitation treatment.

    2014-01-01

    Full Text Available Focus of the text is on psychoanalytic epistemology of agoraphobic syndrome which is still not sufficiently clarified in psychodynamic parameters. Detailed theorethic study starts from the very origins, theoretical and practical suggestions of Sigmund Freud. Early psychoanalytic formulations include psychodynamic models of Karl Abraham, Helene Deutsch and Edoardo Weiss, as well as a number of other significant analysts who gave significant insight to the metapsychological formulations of agoraphobia in the beginning of XX century. After portraying crucial theoretic frames of dynamics of agoraphobia originating from French psychoanalysis, illustrated through the work of Maurice Bouvet and Jannine Chasseguet - Smirgle, author moves towards psychoanalytic models presented to the psychoanalytic community during the first and second decade of XXI century. This segment incorporates autistic objects of agoraphobic neurotic according to Donald Cartwright and synthesis of crucial traits of representations of self and representations of object according to Barbara Milrod. Leading us towards the conclusion author makes a resume of the actual psychoanalytic epistemology of the agoraphoic syndrome pointing out at the centrality of non adequately solved separation - individuation stage, as well as ego defects associated to he agoraphobic syndrome. Specificity of object relations of agoraphobic neurotic she illustrates pointing out at the nature of his relationship with the follower, that psychic fusion which provides the feeling of certainty outside the safety of ones own home. This detailed overview of severely insufficient published literature devoted to agoraphobia is resumed accenting the necessity for its further research, as well as clear notion that although neurotic disorder, agoraphobic syndrome by at least one of its pole gravitates towards nozologycal unit marking personality disorders.

    The short rib-polydactyly syndromes are a heterogeneous group of lethal autosomal recessive disorders (SRP I-IV), which result from cellular ciliary dysfunction during embryogenesis. Diagnosis is conventionally based on radiographic imaging. Since 1976, postmortem investigations of 5 affected fetuses or stillbirths have been undertaken and the visceral abnormalities have been documented. These anomalies are discussed in the context of prenatal differential diagnosis and prognostication following imaging in pregnancy and at autopsy following miscarriage or stillbirth.

    It is a priority to understand that physical activity behaviour over time is a priority in Down syndrome population in order to design and promote succesfull interventions to maintain or increase levels of physical activity. We aimed to study 1 and 2-year changes in objectively measured physical activity among a relatively large sample of adolescents with Down syndrome. This study comprised a total of 99 adolescents with Down syndrome (38 girls) aged from 11 to 20 years old at baseline. Participants with valid accelerometer data at baseline and at least one of the follow-up visits were included in the analysis. Overall, levels of physical activity observed in adolescents with Down syndrome declined from baseline to follow-ups, but these changes were not significant (all P > 0.05). Moderate-to-moderately high tracking of physical activity was observed in adolescents with Down syndrome (all P Down syndrome do not change their levels of physical activity at 2-year follow-ups, but those who met physical activity guidelines presented stronger declines in physical activity over time. © 2017 MENCAP and International Association of the Scientific Study of Intellectual and Developmental Disabilities and John Wiley & Sons Ltd.

    Velo-cardio-facial syndrome (VCFS) has been identified as an important risk factor for psychoses, with up to 32% of individuals with VCFS developing a psychotic illness. Individuals with VCFS thus form a unique group to identify and explore early symptoms and biological correlates of psychosis. In this study, we examined if cortical gyrification pattern, i.e. gyrification index (GI) can be a potential neurobiological marker for psychosis. GIs of 91 individuals with VCFS were compared with 29 siblings and 54 controls. Further, 58 participants with VCFS, 21 siblings and 18 normal controls were followed up after 3 years and longitudinal changes in GI were compared. Additionally, we also correlated longitudinal changes in GI in individuals with VCFS with prodromal symptoms of psychosis on the Scale of Prodromal Symptoms (SOPS). Individuals with VCFS had significantly lower GIs as compared to their siblings and normal controls. Longitudinal examination of GI did not reveal any significant group-time interactions between the three groups. Further, longitudinal change in GI scores in the VCFS group was negatively correlated with positive prodromal symptoms, with the left occipital region reaching statistical significance. The study confirms previous reports that individuals with VCFS have reduced cortical folding as compared to normal controls. However over a period of three years, there is no difference in the rate of change of GI among both individuals with VCFS and normal controls. Finally, our results suggest that neuroanatomical alterations in areas underlying visual processing may be an early marker for psychosis. Copyright © 2012 Elsevier B.V. All rights reserved.

    To determine the effects of average alcohol consumption and changes in alcohol intake on the insulin resistance syndrome parameters in a 3-year follow-up study. Longitudinal study of 1856 and 1529 alcohol drinking men and women in the French DESIR study (Data from an Epidemiological Study on the Insulin Resistance syndrome), aged 30 to 64 years. In men, fasting glucose, body mass index, waist circumference, systolic blood pressure, and HDL-cholesterol were positively associated with average alcohol consumption while there was no association with insulin or triglycerides concentrations. A change in alcohol intake was positively associated with HDL-cholesterol concentration and systolic blood pressure at follow-up. These effects of alcohol could not be attributed specifically to the intake of wine. In women, while the alcohol HDL-cholesterol relation was similar to that found in the men, the only significant effect of average alcohol intake was an increase in systolic blood pressure, with a spurious decrease in blood pressure related to a 3-year increase in alcohol intake. Alcohol only provided a beneficial effect on HDL-cholesterol. The beneficial effect seen by other authors of moderate alcohol drinking on diabetes and cardiovascular risk may be due to effects on parameters other than those included in the current definitions of the insulin resistance syndrome.

    In Mexico, chronic liver disease have been increasingly found along with the rapidly growing prevalence of obesity, diabetes and metabolic syndrome (MS). We aimed to investigate the longitudinal association between these three factors and risk of elevated alanine aminotransferase (ALT) levels (>40 U/L), a marker for liver damage, in a cohort of Mexican adults. Data were obtained from two separate waves of the Mexican Health Worker Cohort Study: Wave 1 (2004-2006) and Wave 2 (2011-2013). Unconditional logistic regression models were employed to determine the cross-sectional and longitudinal association between these risk factors and elevated ALT levels. The prevalence of elevated ALT was significantly higher among men, individuals aged under 60 years, those who were overweight or obese, diabetic, with MS or heavy/binge drinkers. The longitudinal results indicated that weight gain between waves that resulted in a change in body mass index, along with remaining overweight or obese, were significantly associated with an increased risk of elevated ALT levels. A significantly increased risk of developing elevated ALT was also observed among those who acquired diabetes or MS from Wave 1 to Wave 2. Weight gain and acquiring diabetes or MS are associated with a significant risk of having elevated ALT. These results, within the context of the rapid increase in global obesity rates, call urgently for programs to help to prevent chronic liver disease. © 2016 Chinese Medical Association Shanghai Branch, Chinese Society of Gastroenterology, Renji Hospital Affiliated to Shanghai Jiaotong University School of Medicine and John Wiley & Sons Australia, Ltd.

    Blood coagulation plays a crucial role in the blastocyst implantation process and its alteration may be related to in vitro fertilization (IVF) failure. We conducted a prospective observational longitudinal study in women eligible for IVF to explore the association between alterations of coagulation with the IVF outcome and to identify the biomarkers of hypercoagulability which are related with this outcome. Thirty-eight women eligible for IVF (IVF-group) and 30 healthy, age-matched women (control group) were included. In the IVF-group, blood was collected at baseline, 5-8 days after administration of gonadotropin-releasing hormone agonist (GnRH), before and two weeks after administration of human follicular stimulating hormone (FSH). Pregnancy was monitored by measurement of β HCG performed 15 days after embryo transfer. Thrombin generation (TG), minimal tissue factor-triggered whole blood thromboelastometry (ROTEM®), procoagulant phospholipid clotting time (Procoag-PPL®), thrombomodulin (TMa), tissue factor activity (TFa), factor VIII (FVIII), factor von Willebrand (FvW), D-Dimers and fibrinogen were assessed at each time point. Positive IVF occurred in 15 women (40%). At baseline, the IVF-group showed significantly increased TG, TFa and TMa and significantly shorter Procoag-PPL versus the control group. After initiation of hormone treatment TG was significantly higher in the IVF-positive as compared to the IVF-negative group. At all studied points, the Procoag-PPL was significantly shorter and the levels of TFa were significantly higher in the IVF-negative group compared to the IVF-positive one. The D-Dimers were higher in the IVF negative as compared to IVF positive group. Multivariate analysis retained the Procoag-PPL and TG as predictors for the IVF outcome. Diagnosis of women with hypercoagulability and their stratification to risk of IVF failure using a model based on the Procoag-PPL and TG is a feasible strategy for the optimization of IVF efficiency

    Seizures are common in dogs and can be caused by non-epileptic conditions or epilepsy. The clinical course of newly diagnosed epilepsy is sparsely documented. The objective of this study was to prospectively investigate causes for seizures (epileptic and non-epileptic) in a cohort of dogs with new-onset untreated seizures, and for those dogs with newly diagnosed epilepsy to investigate epilepsy type, seizure type and the course of disease over time, including the risk of seizure recurrence. Untreated client-owned dogs experiencing new-onset seizures were prospectively enrolled in a longitudinal observational study including clinical investigations and long-term monitoring at the Copenhagen University Hospital for Companion Animals. A baseline clinical assessment was followed by investigator/owner contact every eight weeks from inclusion to death or end of study. Inclusion of dogs was conducted from November 2010 to September 2012, and the study terminated in June 2014. One hundred and six dogs were included in the study. Seventy-nine dogs (74.5%) were diagnosed with epilepsy: 61 dogs (77.2%) with idiopathic epilepsy, 13 dogs (16.5%) with structural epilepsy and five dogs (6.3%) with suspected structural epilepsy. A non-epileptic cause for seizures was identified in 13 dogs and suspected in 10 dogs. Four dogs in which no cause for seizures was identified experienced only one seizure during the study. In dogs with idiopathic epilepsy 60% had their second epileptic seizure within three months of seizure onset. Twenty-six dogs with idiopathic epilepsy (43%) completed the study without receiving antiepileptic treatment. The natural course of idiopathic epilepsy (uninfluenced by drugs) was illustrated by highly individual and fluctuating seizure patterns, including long periods of remission. Cluster seizures motivated early treatment. In a few dogs with a high seizure frequency owners declined treatment against the investigators advice. Epilepsy is the most likely

    The relationships between uric acid and chronic disease risk factors such as metabolic syndrome, type 2 diabetes mellitus, and hypertension have been studied in adults. However, whether these relationships exist in adolescents is unknown. We randomly selected 8,005 subjects who were between 10 to 15 years old at baseline. Measurements of uric acid were used to predict the future occurrence of metabolic syndrome, hypertension, and type 2 diabetes. In total, 5,748 adolescents were enrolled and ...

    Congenital central hypoventilation syndrome (CCHS) is a rare dysgenetic form of neurocristopathy associated with dysfunction of the autonomic nervous system. Ophthalmologic abnormalities are reported in CCHS children, and range from pupillary and iris abnormalities to ptosis, strabismus and convergence deficiency. Since earlier CCHS diagnosis and multidisciplinary management, combined with improved ventilatory support techniques, the lifespan of children with CCHS has been considerably lengthened. The oldest of them have now reached adult age and we report in this study the results of their ophthalmologic examination. Nine CCHS adult patients were prospectively included during a 14-month period. Each patient underwent complete ophthalmologic examination, static pupillometry with scotopic and photopic pupillary diameter (PD) measures, Humphrey 24-2 visual field analysis, macular OCT and complete orthoptic assessment including a Hess-Lancaster test. Ophthalmologic abnormalities were found in six of the nine patients (66%). The main features were strabismus in six patients (66%). Four patients (44%) displayed abnormal pupillary function, with a decrease in average scotopic PD (3.8 ± 1.4 mm), average photopic PD (3.5 ± 1.2 mm), and average percentage of pupillary constriction (7.6 ± 8.5%). Three patients (33%) exhibited iris abnormalities such as iris atrophy, smooth iris surface and atrophic sphincter. This study allowed the description of ophthalmologic abnormalities occurring in CCHS in a series of adult patients, thus improving current knowledge of the disease. The prevalence of pupillary and iris lesions were lower than those observed in a series of children, suggesting that they could be considered as systemic disease severity markers.

    Full Text Available Objective: Autoimmune polyendocrine syndrome type 1 (APS1 is a rare autosomal recessive disorder characterized by progressive organ-specific autoimmunity. There is scant information on APS1 in ethnic groups other than European Caucasians. We studied clinical aspects and autoimmune regulator (AIRE gene mutations in a cohort of Indian APS1 patients. Design: Twenty-three patients (19 families from six referral centres in India, diagnosed between 1996 and 2016, were followed for [median (range] 4 (0.2–19 years. Methods: Clinical features, mortality, organ-specific autoantibodies and AIRE gene mutations were studied. Results: Patients varied widely in their age of presentation [3.5 (0.1–17 years] and number of clinical manifestations [5 (2–11]. Despite genetic heterogeneity, the frequencies of the major APS1 components (mucocutaneous candidiasis: 96%; hypoparathyroidism: 91%; primary adrenal insufficiency: 55% were similar to reports in European series. In contrast, primary hypothyroidism (23% occurred more frequently and at an early age, while kerato-conjunctivitis, urticarial rash and autoimmune hepatitis were uncommon (9% each. Six (26% patients died at a young age [5.8 (3–23 years] due to septicaemia, hepatic failure and adrenal/hypocalcaemic crisis from non-compliance/unexplained cause. Interferon-α and/or interleukin-22 antibodies were elevated in all 19 patients tested, including an asymptomatic infant. Eleven AIRE mutations were detected, the most common being p.C322fsX372 (haplotype frequency 37%. Four mutations were novel, while six others were previously described in European Caucasians. Conclusions: Indian APS1 patients exhibited considerable genetic heterogeneity and had highly variable clinical features. While the frequency of major manifestations was similar to that of European Caucasians, other features showed significant differences. A high mortality at a young age was observed.

    This study investigated the impact of anxiety evaluated within 2 weeks of an acute coronary syndrome (ACS) episode on depressive outcomes at a 1-year follow-up assessment. In 828 ACS patients, anxiety was determined by Hospital Anxiety and Depression Scale-anxiety subscale at baseline, and DSM-IV depressive disorders and depressive symptoms were evaluated both at baseline and follow-up. Anxiety at baseline was significantly associated with depressive disorder at the follow-up and less improvement in depressive symptoms over 1-year. Anxiety had negative longitudinal impacts on depressive outcomes of ACS, and therefore evaluation of anxiety could be recommended in recently developed ACS patients.

    Experience with craniocerebral trauma in 712 physically abused children is reviewed. Ninety-three (13%) had evidence of head trauma (cranial and/or intracranial). Seventy-seven of these patients had computed tomography (CT) of the head, and 47 had CT evidence of intracranial injury. Extracerebral fluid collections, predominantly convexity subdural hemorrhage, were the most common acute intracranial lesions. Concurrent intracranial and skeletal trauma (cranial and/or ectracranial) was present in 33 of the 47 patients (70%) with intracranial injury. A high incidence of skull fractures (45%) in those children with intracranial lesions suggest a significant role for impact head injuries (''battering'') in the pathogenesis of craniocerebral trauma in the child abuse syndrome. Greater emphasis on CT examination in evaluation of the abuse infant and child is recommended.

    There has been little evaluation in longitudinal epidemiologic studies of the effect of metabolic syndrome (MetS) on periodontal status. The specific aim of this longitudinal study is to investigate whether MetS in the Japanese population could be a risk factor for periodontal disease. A total of 125 older adults from Japan for whom data were available for the years 2003 to 2006 were selected for the current study. Full-mouth periodontal status, measured as clinical attachment level (CAL), was recorded at baseline and in follow-up examinations. Development of periodontal disease was considered to be ≥2 teeth demonstrating a longitudinal loss of proximal attachment of ≥3 mm at the follow-up dental examination. A multivariable Poisson regression model with robust error variance was used to evaluate the association of MetS defined by the modified National Cholesterol Education Program Adult Treatment Panel III criteria with development of periodontal disease. Adjustments for sex, income, education, smoking status, number of teeth at baseline, mean CAL at baseline, pattern of visits to a dentist, and brushing frequency were considered. The prevalence of MetS was 21.6% (27/125). Study participants with MetS were approximately 2.6 times more likely to develop periodontal disease (adjusted relative risk 2.58, 95% confidence interval 1.17 to 5.67) after simultaneous adjustment for other covariates. These findings support the hypothesis that MetS may be a risk factor for periodontal disease in older Japanese individuals. Additional studies with larger, more diverse populations and more complete information are needed to substantiate the findings.

    The BLAS 2 T (bilingual aphasia in stroke-study team) initiative has been a multi-center attempt to investigate longitudinal changes in language function in a cohort of stroke subjects. This report discusses linguistic performance in four cases from the BLAS 2 T database who demonstrated coprolalia as an irresistible urge to say obscene words.  Coprolalia was found to partly resolve in a 30-day follow-up in three cases. Recognition of coprolalia and language recovery patterns in bilingual aphasic patients with stroke would potentially lead to their even better individualized care and neurolinguistic/cognitive rehabilitation.

    BACKGROUND: Burning Mouth Syndrome (BMS) is a chronic disease characterized by absence of any lesions and burning of the oral mucosa associated to a sensation of dry mouth and/or taste alterations. The purpose of our study is to estimate signs and symptoms of Temporomandibular Disorders (TMD) in patients with BMS and to investigate for the existence of an association between BMS and TMD. MATERIALS AND METHODS: Forty-four BMS patients were enrolled; BMS subtype was established according to the classification of Lamey. After a gnathological evaluation, according to the protocol of the European Academy of Craniomandibular Disorders, patients were classified by RDC/TMD criteria. The data were compared and analyzed using a chi-square test to describe the existence of an association between BMS and TMD. RESULTS: 65.9% the BMS patients showed disorders classified as primary signs and symptoms of TMD according to RDC / TMD criteria, and 72.7% showed parafunctional habits. The chi-square test revealed a statistically significant association (p = 0.035) between BMS and TMD. CONCLUSION: The data suggest that there is a possible relationship not yet well understood between BMS and TMD, may be for neurophatic alterations assumed for BMS that could be also engaged in TMD pathogenesis.

    Full Text Available Since she was 4 years old, the patient had exhibited frequent convulsive seizures, and she experienced severe headaches and depression in adulthood. At the age of 37 years, cerebral calcifications were detected, but she exhibited no cognitive or motor problems. She suffered a cerebral haemorrhage at 49 years old and experienced cognitive dysfunction, dysarthria, dysphagia, and left-hemiparesis as sequelae. After undergoing gastrostomy, she exhibited very slow cognitive deterioration associated with speech disturbance over more than 10 years. She also gradually developed limb spasticity with Babinski signs. Repeated computerised tomography scans revealed unexpected changes including 2 cysts that appeared separately after small haemorrhages, an intracerebral haemorrhage, and intra-cyst bleeding. These longitudinal scans also showed progressive ventricular dilatation and expansion of the leukoencephalopathy, but there were no apparent changes in the intracranial calcifications. Magnetic resonance imaging revealed numerous microbleeds, and magnetic resonance angiography revealed irregularity of the cerebral artery walls with stoppage. Her SNORD118 gene exhibited compound heteromutation of c.38C > G and c.116G > C on different alleles. She was finally diagnosed with leukoencephalopathy with brain calcifications and cysts (Labrune syndrome at the age of 61 years. Past reports have suggested that diffuse cerebral microangiopathy underlies Labrune syndrome's pathogenesis, but we speculate that cerebral macroangiopathy may also underlie it.

    Chronic pain symptoms often change over time, even in individuals who have had symptoms for years. Studying biological factors that predict trends in symptom change in chronic pain may uncover novel pathophysiological mechanisms and potential therapeutic targets. In this study, we investigated whether brain functional connectivity measures obtained from resting-state functional magnetic resonance imaging at baseline can predict longitudinal symptom change (3, 6, and 12 months after scan) in urologic chronic pelvic pain syndrome. We studied 52 individuals with urologic chronic pelvic pain syndrome (34 women, 18 men) who had baseline neuroimaging followed by symptom tracking every 2 weeks for 1 year as part of the Multidisciplinary Approach to the Study of Chronic Pelvic Pain (MAPP) Research Network study. We found that brain functional connectivity can make a significant prediction of short-term (3 month) pain reduction with 73.1% accuracy (69.2% sensitivity and 75.0% precision). In addition, we found that the brain regions with greatest contribution to the classification were preferentially aligned with the left frontoparietal network. Resting-state functional magnetic resonance imaging measures seemed to be less informative about 6- or 12-month symptom change. Our study provides the first evidence that future trends in symptom change in patients in a state of chronic pain may be linked to functional connectivity within specific brain networks.

    to investigate visual function pre- and post surgery in children with single-suture non-syndromic craniosynostosis Twenty-nine infants (12 with sagittal synostosis, 10 with trigonocephaly and 7 with anterior plagiocephaly) were longitudinally evaluated using a battery of tests assessing various aspects of visual function, including ocular behaviour, acuity, visual fields and fixation shift. All infants were assessed before surgery and 2, 6 and 12 months after surgery. Before surgery only 16% of infants had completely normal visual function, while on the assessment performed 12 months after surgery, the number with normal results on all the tests increased to 65%. The only abnormalities found 12 months after surgical correction were mainly found on abnormal oculomotor behaviour in infants with plagiocephaly. Abnormalities of visual function were not frequent in infants with non-syndromic craniosynostosis who underwent surgical correction. Approximately half of the patients had some visual abnormalities before surgery, which subsequently improved, showing a delayed visual maturation rather than persistent abnormalities.

    Elevated uric acid (UA) is associated with the presence of the metabolic syndrome (MetS). In a prospective cohort study, we assessed whether baseline and longitudinal change in UA were risk factors for development of MetS and its individual components. We included 3087 women and 2996 men who had UA measured in the population based Tromsø Study 1994-95. The participants were stratified according to body mass index (BMI). Endpoints were MetS and each component of the syndrome after 7 years, according to the revised National Cholesterol Education Program's Adult Treatment Panel III (NCEP-ATP III) definition. Multiple logistic regression analyses showed that higher baseline UA was associated with higher odds of developing elevated blood pressure in overweight subjects (BMI ≥ 25 kg/m(2), odds ratio [OR] per 59 μmol/L UA increase 1.44, 95 % confidence interval [CI] = 1.17-1.77, P = 0.001), but not in normal-weight subjects (BMI < 25 kg/m(2), P for interaction = 0.04). Overweight also modified the association between baseline UA and the development of elevated fasting glucose (P for interaction = 0.01). UA was a predictor of MetS in all subjects (OR per 59 μmol/L UA increase 1.29, 95 % CI 1.18-1.41, P < 0.001). Furthermore, longitudinal UA change was independently associated with the development of MetS in all subjects (OR per 59 μmol/L UA increase over 7 years 1.28, 95 % CI 1.16-1.42, P < 0.001). Increased levels of baseline UA independently predicted development of elevated blood pressure and higher fasting glycemia in the overweight, but not the normal-weight subjects. Baseline UA and longitudinal increase in UA over 7 years was associated with the development of MetS in all subjects. Whether increased UA should be treated differently in normal-weight and overweight persons needs further study.

    Full Text Available The relationships between uric acid and chronic disease risk factors such as metabolic syndrome, type 2 diabetes mellitus, and hypertension have been studied in adults. However, whether these relationships exist in adolescents is unknown. We randomly selected 8,005 subjects who were between 10 to 15 years old at baseline. Measurements of uric acid were used to predict the future occurrence of metabolic syndrome, hypertension, and type 2 diabetes. In total, 5,748 adolescents were enrolled and followed for a median of 7.2 years. Using cutoff points of uric acid for males and females (7.3 and 6.2 mg/dl, respectively, a high level of uric acid was either the second or third best predictor for hypertension in both genders (hazard ratio: 2.920 for males, 5.222 for females; p<0.05. However, uric acid levels failed to predict type 2 diabetes mellitus, and only predicted metabolic syndrome in males (hazard ratio: 1.658; p<0.05. The same results were found in multivariate adjusted analysis. In conclusion, a high level of uric acid indicated a higher likelihood of developing hypertension in both genders and metabolic syndrome in males after 10 years of follow-up. However, uric acid levels did not affect the occurrence of type 2 diabetes in both genders.

    Fragile X syndrome (FXS) and Down syndrome (DS) are the two leading genetic causes of intellectual disability, and FXS is the most common known genetic condition associated with autism. Both FXS and DS are associated with significant language impairment, but little is known about expressive language across domains over time or the role of autism in language development in FXS. To compare three domains of language production (vocabulary, syntax, pragmatics) over time within and across groups of boys with FXS with and without autism spectrum disorder (FXS-ASD, FXS-O), boys with DS, and typically developing (TD) boys. Twenty-nine boys with FXS-O, 40 boys with FXS-ASD, 34 boys with DS, and 48 younger TD boys of similar non-verbal mental age living in the United States participated in the study. The Antonyms, Syntax Construction and Pragmatic Judgment subtests of the Comprehensive Assessment of Spoken Language were administered annually over 3 years. TD boys scored higher than all other groups on all three subtests; boys with FXS-O and FXS-ASD scored higher than boys with DS in Syntax Construction; and boys with FXS-O scored higher than boys with FXS-ASD in Pragmatic Judgment. Within-group patterns varied between groups. Overall, the TD group showed significantly more change over time than all other groups. Findings suggest that expressive language skills and growth across various domains are more impaired in boys with FXS and DS than would be expected based on non-verbal mental age, that for boys with DS syntax is more impaired than would be expected based on intellectual disability, and that autism status affects pragmatic language in boys with FXS. Findings suggest that language production across domains should be addressed during assessment and intervention for boys with FXS and boys with DS, with differing group profiles also suggesting potentially different areas of focus. © 2013 Royal College of Speech and Language Therapists.

    The most recent Cassini RADAR images of Titan show widespread regions (up to 1500 kilometers by 200 kilometers) of near-parallel radar-dark linear features that appear to be seas of longitudinal dunes similar to those seen in the Namib desert on Earth. The Ku-band (2.17-centimeter wavelength) images show approximately 100-meter ridges consistent with duneforms and reveal flow interactions with underlying hills. The distribution and orientation of the dunes support a model of fluctuating surface winds of approximately 0.5 meter per second resulting from the combination of an eastward flow with a variable tidal wind. The existence of dunes also requires geological processes that create sand-sized (100- to 300-micrometer) particulates and a lack of persistent equatorial surface liquids to act as sand traps.

    Classically, clinical trials are based on the placebo-control design. Our aim was to analyze the placebo effect in Huntington's disease. Placebo data were obtained from an international, longitudinal, placebo-controlled trial for Huntington's disease (European Huntington's Disease Initiative Study Group). One-hundred and eighty patients were evaluated using the Unified Huntington Disease Rating Scale over 36 months. A placebo effect was defined as an improvement of at least 50% over baseline scores in the Unified Huntington Disease Rating Scale, and clinically relevant when at least 10% of the population met it. Only behavior showed a significant placebo effect, and the proportion of the patients with placebo effect ranged from 16% (first visit) to 41% (last visit). Nondepressed patients with better functional status were most likely to be placebo-responders over time. In Huntington's disease, behavior seems to be more vulnerable to placebo than overall motor function, cognition, and function Copyright © 2011 Movement Disorder Society.

  12. Statistical analysis of radar observed F region irregularities from three longitudinal sectors

    2013-12-01

    Full Text Available Equatorial Spread F (ESF is a manifestation of ionospheric interchange instabilities in the nighttime equatorial F region. These instabilities generate plasma density irregularities with scale sizes ranging from centimetres to thousands of kilometres. The irregularities can be detected from a variety of instruments such as digisonde, coherent and incoherent scatter radars, in situ space probes, and airglow photometers. In the present study, occurrence statistics of the ESF, based on various parameters are presented using data obtained from the VHF radars located at three longitudinally separated equatorial stations: Christmas Island (2° N, 202.6° E, 2.9° N dip latitude, São Luís (2.59° S, 315.8° E, 0.5° S dip latitude and Jicamarca (12° S, 283.1° E, 0.6° N dip latitude. The ESF parameters presented here are the onset altitude, onset time (onset refers to first appearance of signal in the radar field of view of the bottom-type and plume, and the peak altitude of the plume. Recent studies have used these parameters to classify the spread F occurrence characteristics. The present study reveals novel features namely, the dependence of ESF parameters on the seasonal, solar flux, declination angle and longitudinal dependence from the three radar sites. In addition, we also present an empirical model to determine the nature of these ESF parameters as a function of the solar flux which may enable us to forecast (with 30 min to 1 h tolerance the plume occurrence at any longitude located in between São Luís and Christmas Island.

    Full Text Available BACKGROUND: The metabolic syndrome (MetS has been known as partly heritable, while the number of genetic studies on MetS and metabolic-related traits among Chinese elderly was limited. METHODS: A cross-sectional analysis was performed among 2 014 aged participants from September 2009 to June 2010 in Beijing, China. An additional longitudinal study was carried out among the same study population from 2001 to 2010. Biochemical profile and anthropometric parameters of all the participants were measured. The associations of 23 SNPs located within 17 candidate genes (MTHFR, PPARγ, LPL, INSIG, TCF7L2, FTO, KCNJ11, JAZF1, CDKN2A/B, ADIPOQ, WFS1, CDKAL1, IGF2BP2, KCNQ1, MTNR1B, IRS1, ACE with overweight and obesity, diabetes, metabolic phenotypes, and MetS were examined in both studies. RESULTS: In this Chinese elderly population, prevalence of overweight, central obesity, diabetes, dyslipidemia, hypertension, and MetS were 48.3%, 71.0%, 32.4%, 75.7%, 68.3% and 54.5%, respectively. In the cross-sectional analyses, no SNP was found to be associated with MetS. Genotype TT of SNP rs4402960 within the gene IGF2BP2 was associated with overweight (odds ratio (OR  = 0.479, 95% confidence interval (CI: 0.316-0.724, p = 0.001 and genotype CA of SNP rs1801131 within the gene MTHFR was associated with hypertension (OR = 1.560, 95% CI: 1.194-2.240, p = 0.001. However, these associations were not observed in the longitudinal analyses. CONCLUSIONS: The associations of SNP rs4402960 with overweight as well as the association of SNP rs1801131 with hypertension were found to be statistically significant. No SNP was identified to be associated with MetS in our study with statistical significance.

    The progression of obstructive airway diseases (OADs) including asthma, chronic obstructive pulmonary disease (COPD) and asthma-COPD overlap syndrome in older adults is not well understood. To examine the prognosis of OADs and to identify potential determinants for longitudinal changes in clinical outcomes. We consecutively recruited 99 older adults (>55 years) with OADs who underwent a multidimensional assessment at baseline and 4 years which involved spirometry, 6-min walk distance (6MWD), assessments of health status (Saint George's Respiratory Questionnaire, SGRQ), comorbidity, and serum and sputum biomarkers. All-cause mortality and respiratory hospitalisation during the follow-up period were recorded. Clinical outcomes were compared between basal and final visits, and changes in clinical outcomes were compared among asthma, COPD and asthma-COPD overlap groups. Associations between clinical parameters, biomarkers and prognosis were examined. After a median follow-up of 4.2 years, outcome data were available for 75 (75.8%) patients. There were 16 (16.2%) deaths. The BODE index predicted all-cause mortality in older people with OADs. While spirometry, 6MWD and SGRQ deteriorated significantly over the 4 years, there was significant heterogeneity in the longitudinal changes in these clinical outcomes. Participants with COPD had a significant decline in FEV1 (p = 0.003), SGRQ (p = 0.030) and 6MWD [decline of 75.5 (93.4) m, p = 0.024]. The change in 6MWD was lower in the asthma-COPD overlap group. Airflow reversibility was associated with a reduced decline in 6MWD. COPD patients had a poor prognosis compared with asthma and asthma-COPD overlap patients. The BODE index is a useful prognostic indicator in older adults with OADs. Both airway disease diagnosis and BODE index warrant specific attention in clinical practice. © 2013 S. Karger AG, Basel.

    We present a series of 38 cases of longitudinal splitting of the peroneus brevis tendon revealed by MR imaging (12 lesions were confirmed at surgery). MRI enabled classification in four surgical grades.The frequency of such lesions in chronic ankle instability as observed in our series is often reported in the literature. Bilateral cases are common. Asymptomatic cases do occur, especially in grades I and II. MRI has been shown to be a very effective investigation for demonstrating this tendinous lesion: the proton density weighted sequence in the axial plane is the most adequate sequence.

    The longitudinal spin-Seebeck effect (LSSE) has been investigated in cobalt ferrite (CFO), an exceptionally hard magnetic spinel ferrite. A bilayer of a polycrystalline Pt and an epitaxially-strained CFO(110) exhibiting an in-plane uniaxial anisotropy was prepared by reactive rf sputtering technique. Thermally generated spin voltage in the CFO layer was measured via the inverse spin-Hall effect in the Pt layer. External-magnetic-field (H) dependence of the LSSE voltage (V{sub LSSE}) in the Pt/CFO(110) sample with H ∥ [001] was found to exhibit a hysteresis loop with a high squareness ratio and high coercivity, while that with H∥[11{sup -}0] shows a nearly closed loop, reflecting the different anisotropies induced by the epitaxial strain. The magnitude of V{sub LSSE} has a linear relationship with the temperature difference (ΔT), giving the relatively large V{sub LSSE} /ΔT of about 3 μV/K for CFO(110) which was kept even at zero external field.

    On 20 August 2010 an energetic disturbance triggered damped large-amplitude longitudinal (LAL) oscillations in almost an entire filament. In the present work we analyze this periodic motion in the filament to characterize the damping and restoring mechanism of the oscillation. Our method involves placing slits along the axis of the filament at different angles with respect to the spine of the filament, finding the angle at which the oscillation is clearest, and fitting the resulting oscillation pattern to decaying sinusoidal and Bessel functions. These functions represent the equations of motion of a pendulum damped by mass accretion. With this method we determine the period and the decaying time of the oscillation. Our preliminary results support the theory presented by Luna and Karpen (2012) that the restoring force of LAL oscillations is solar gravity in the tubes where the threads oscillate, and the damping mechanism is the ongoing accumulation of mass onto the oscillating threads. Following an earlier paper, we have determined the magnitude and radius of curvature of the dipped magnetic flux tubes hosting a thread along the filament, as well as the mass accretion rate of the filament threads, via the fitted parameters.

  19. Longitudinal MRI assessment: the identification of relevant features in the development of Posterior Fossa Syndrome in children

    2015-03-01

    Up to 25% of children who undergo brain tumour resection surgery in the posterior fossa develop posterior fossa syndrome (PFS). This syndrome is characterised by mutism and disturbance in speech. Our hypothesis is that there is a correlation between PFS and the occurrence of hypertrophic olivary degeneration (HOD) in lobes within the posterior fossa, known as the inferior olivary nuclei (ION). HOD is exhibited as an increase in size and intensity of the ION on an MR image. Intra-operative MRI (IoMRI) is used during surgical procedures at the Alder Hey Children's Hospital, Liver- pool, England, in the treatment of Posterior Fossa tumours and allows visualisation of the brain during surgery. The final MR scan on the IoMRI allows early assessment of the ION immediately after the surgical procedure. The longitudinal MRI data of 28 patients was analysed in a collaborative study with Alder Hey Children's Hospital, in order to identify the most relevant imaging features that relate to the development of PFS, specifically related to HOD. A semi-automated segmentation process was carried out to delineate the ION on each MRI. Feature selection techniques were used to identify the most relevant features amongst the MRI data, demographics and clinical data provided by the hospital. A support vector machine (SVM) was used to analyse the discriminative ability of the selected features. The results indicate the presence of HOD as the most efficient feature that correlates with the development of PFS, followed by the change in intensity and size of the ION and whether HOD occurred bilaterally or unilaterally.

    Parents influence a child's diet by modeling food choices, selecting the food they make available, and controlling the child's intake. Few studies have examined the covariation between parent's behavior management practices and their guidance and support for a young child's nutritional environment in early childhood. We hypothesized that parents' positive behavior support (PBS), characterized as skillful behavior management and proactive structuring of children's activities, would predict dietary quality over the course of early childhood (age 2 to 5 years), a critical period for the development of a dietary lifestyle. Participants included 731 culturally diverse, low-income families in a randomized, controlled trial of the Family Check-Up. Families participated in a yearly home visit videotaped assessment PBS and dietary quality of meals parents served to their children were assessed by coding videotapes of structured parent-child interactions. A cross-lagged panel model was used to evaluate the longitudinal relation between PBS and the dietary quality of meals served during a meal preparation task. Analyses revealed that PBS repeatedly predicted meals' dietary quality the following year: age 2-3 (β = .30), age 3-4 (β = 0.14), age 4-5 (β = 0.37). Dietary quality significantly predicted PBS 1 year later: age 3-4 (β = 0.16), age 4-5 (β = 0.14). As expected, the relative strength of the relationship from PBS to dietary quality was significantly stronger than the reverse, from dietary quality to PBS. Positive behavior management and proactive parenting practices are an important foundation for establishing a healthy nutritional environment for young children. These findings suggest that family-centered prevention interventions for pediatric obesity may benefit from targeting PBS in service of promoting better dietary quality.

    Bone mass and density are low in females with Rett syndrome. This study used Dual energy x-ray absorptiometry to measure annual changes in z-scores for areal bone mineral density (aBMD) and bone mineral content (BMC) in the lumbar spine and total body in an Australian Rett syndrome cohort at baseline and then after three to four years. Bone mineral apparent density (BMAD) was calculated in the lumbar spine. Annual changes in lean tissue mass (LTM) and bone area (BA) were also assessed. The effects of age, genotype, mobility, menstrual status and epilepsy diagnosis on these parameters were also investigated. The baseline sample included 97 individuals who were representative of the total live Australian Rett syndrome population under 30years in 2005 (n=274). Of these 74 had a follow-up scan. Less than a quarter of females were able to walk on their own at follow-up. Bone area and LTM z-scores declined over the time between the baseline and follow-up scans. Mean height-standardised z-scores for the bone outcomes were obtained from multiple regression models. The lumbar spine showed a positive mean annual BMAD z-score change (0.08) and a marginal decrease in aBMD (-0.04). The mean z-score change per annum for those 'who could walk unaided' was more positive for LS BMAD (p=0.040). Total body BMD mean annual z-score change from baseline to follow-up was negative (-0.03). However this change was positive in those who had achieved menses prior to the study (0.03, p=0,040). Total body BMC showed the most negative change (-0.60), representing a decrease in bone mineral content over time. This normalised to a z-score change of 0.21 once adjusted for the reduced lean tissue mass mean z-score change (-0.21) and bone area mean z-score change (-0.14). Overall, the bone mineral content, bone mineral density, bone area and lean tissue mass z-scores for all outcome measures declined, with the TB BMC showing significant decreases. Weight, height and muscle mass appear to have

    This study was performed to explore possible environmental risk factors, including indoor chemicals, mold, and dust mite allergens, which could cause sick building syndrome (SBS)-type symptoms in new houses. The study was conducted in 2004 and 2005 and the final study population consisted of 86 men and 84 women residing in Okayama, Japan. The indoor concentrations of indoor aldehydes, volatile organic compounds, airborne fungi, and dust mite allergens in their living rooms were measured and the longitudinal changes in two consecutive years were calculated. A standardized questionnaire was used concomitantly to gather information on frequency of SBS-type symptoms and lifestyle habits. About 10% of the subjects suffered from SBS in the both years. Crude analyses indicated tendencies for aldehyde levels to increase frequently and markedly in the newly diseased and ongoing SBS groups. Among the chemical factors and molds examined, increases in benzene and in Aspergillus contributed to the occurrence of SBS in the logistic regression model. Indoor chemicals were the main contributors to subjective symptoms associated with SBS. A preventive strategy designed to lower exposure to indoor chemicals may be able to counter the occurrence of SBS.

    To investigate longitudinal performance on an executive functioning task among individuals with obstructive sleep apnea syndrome (OSAS) and the impact of obesity on performance. Participants completed the Trail Making Test Part B (TMT-B), which is an executive functioning task that measured cognitive flexibility, at baseline, 3-, 6-, and 12-month follow-ups. Hierarchical linear modeling (HLM) analyses were used to assess participants' initial performance on the task, as well the trajectories of growth on the task across time points. Additionally, body mass index (BMI) was included in the estimations of fixed and random effects as a predictor of performance. There were no significant differences between obese and non-obese individuals on the cognitive flexibility task at baseline. However, obese and non-obese individuals differed significantly in their linear and quadratic rates of growth across time points. This study suggests that obese and non-obese individuals may differentially respond to Continuous Positive Airway Pressure (CPAP) treatment (as related to cognitive flexibility). Future research should examine the impact of weight loss on the neuropsychological sequelae of obese individuals with OSAS. Copyright © 2015 Asia Oceania Association for the Study of Obesity.

    We report the observation of the magnetic field induced circular differential deflection of light at the interface of a Faraday medium. The difference in the angles of refraction or reflection between the two circular polarization components is a function of the magnetic field strength and the Verdet constant. The reported phenomena permit the observation of the Faraday effect not via polarization rotation in transmission, but via changes in the propagation direction in refraction or in refle...

    Full Text Available Many people living with HIV access healthcare systems through the emergency department (ED, and increased ED use may be indicative of disenfranchisement with primary HIV care, under-managed comorbid disease, or coincide with use of other healthcare resources. The goal of this study was to investigate ED use by HIV-infected prisoners transitioning to communities.We evaluated ED use by 151 HIV-infected released prisoners who were enrolled in a randomized controlled trial of directly administered versus self-administered antiretroviral therapy in Connecticut. Primary outcomes were quantity and type of ED visits and correlates of ED use were evaluated with multivariate models by Poisson regression.In the 12 months post-release, there were 227 unique ED contacts made by 85/151 (56% subjects. ED visits were primarily for acute febrile syndromes (32.6% or pain (20.3%, followed by substance use issues (19.4%, trauma (18%, mental illness (11%, and social access issues (4.4%. Compared to those not utilizing the ED, users were more likely to be white, older, and unmarried, with less trust in their physician and poorer perceived physical health but greater social support. In multivariate models, ED use was correlated with moderate to severe depression (IRR = 1.80, being temporarily housed (IRR = 0.54, and alcohol addiction severity (IRR = 0.21 but not any surrogates of HIV severity.EDs are frequent sources of care after prison-release with visits often reflective of social and psychiatric instability. Future interventions should attempt to fill resource gaps, engage released prisoners in continuous HIV care, and address these substantial needs.

    The progeria syndrome (Hutchinson-Gilford) is an uncommon disease. A peculiar shape of the proximal radial metaphyseal region caused by an infolding of the cortex was observed on CT in 2 brothers suffering from this disorder, a feature not previously reported. A brief review of the radiologic literature was undertaken. This new observation needs to be further evaluated as it may provide a clinching diagnostic feature of this disease. (orig.).

    To evaluate predictors of persistence of attention deficit/hyperactivity disorder (ADHD) in a large sample of children with velo-cardio-facial syndrome (VCFS) with and without ADHD followed prospectively into adolescence. Children with VCFS with (n = 37) and without (n = 35) ADHD who were on average 11 years old at the baseline assessment and 15 years old at the follow-up assessment were comprehensively assessed with structured diagnostic interviews and assessments of behavioral, cognitive, social, school, and family functioning. Control participants both with and without ADHD were also followed prospectively. In adolescence, 65% of children with VCFS continued to have findings consistent with ADHD. Childhood predictors of persistence were higher rates of familial ADHD, having childhood depression, having higher levels of hyperactivity, and a larger number of intrusion errors on a verbal list learning test at baseline. Approximately 15% of children with VCFS who did not have ADHD at Time 1 met diagnostic criteria for ADHD at Time 2. All of these children had subthreshold ADHD symptoms at Time 1. These findings prospectively confirm that persistence of ADHD into adolescence in VCFS is predicted by childhood variables that have been previously documented in the non-VCFS ADHD literature.

    Aim Only a few studies have examined the relationship between Tourette syndrome or chronic tic disorder and socio-economic status (SES). Existing studies are primarily cross-sectional, arise from specialty clinics, and use single measures of SES. In this study we examine this relationship in a longitudinal, population-based sample. Method Data are from 7152 children born during 1991 and 1992 in the county of Avon, UK, from the Avon Longitudinal Study of Parents and Children, who were followed up to age 13. After exclusions for intellectual disability* and autism, 6768 participants (3351 males [49.5%]) and 3417 females [50.5%]) remained. Parental SES was assessed using multiple measures during pregnancy and at 33 months of age. Presence of Tourette syndrome or chronic tics was determined from repeated maternal questionnaires up to when the child was 13 years of age. Results Multiple SES measures were associated with an approximately twofold increased risk of Tourette syndrome and chronic tics. A postnatal composite factor score (lowest vs highest tertile odds ratio 2.09, 95% confidence interval 1.38–3.47) provided the best fit to the data. Interpretations As is seen in several childhood conditions, such as cerebral palsy and autism, lower SES is a risk factor for Tourette syndrome/chronic tics. Potential explanations include differential exposure to environmental risk factors or parental psychopathology as a measure of an increased genetic risk leading to decreased parental SES.

    To estimate the association between regular consumption of sweetened soft drinks, natural fruit juice, and coconut water with metabolic syndrome (MetS). This was a cross-sectional study including men and women aged 35-74 years from the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil) Study, excluding patients with type 2 diabetes. The main explanatory variables were beverage consumption and the outcome variable was metabolic syndrome (Adult Treatment Panel III). After adjustments, a daily intake of 250 ml of soft drink increased the chance of metabolic syndrome (odds ratio [OR] = 1.95; 95% confidence interval [CI], 1.60-2.38). There was no association between coconut water and MetS. Moderate consumption of fruit juices has low odds of MetS compared to no consumption. Our results add evidence to potential negative effects of sweetened soft drinks on cluster metabolic abnormalities in middle-income countries.

    New competencies may be learned through active experience (learning by doing) or observation of others' experience (learning by observation). Observing another person performing a complex action accelerates the observer's acquisition of the same action, limiting the time-consuming process of learning by doing. Here, we compared learning by observation and learning by doing in individuals with Prader-Willi syndrome (PWS). It is hypothesized that PWS individuals could show more difficulties with learning by observation than learning by doing because of their specific difficulty in interpreting and using social information. The performance of 24 PWS individuals was compared with that of 28 mental age (MA)- and gender-matched typically developing (TD) children in tasks of learning a visuo-motor sequence by observation or by doing. To determine whether the performance pattern exhibited by PWS participants was specific to this population or whether it was a nonspecific intellectual disability effect, we compared the PWS performances with those of a third MA- and gender-matched group of individuals with Williams syndrome (WS). PWS individuals were severely impaired in detecting a sequence by observation, were able to detect a sequence by doing, and became as efficient as TD children in reproducing an observed sequence after a task of learning by doing. The learning pattern of PWS children was reversed compared with that of WS individuals. The observational learning deficit in PWS individuals may be rooted, at least partially, in their incapacity to understand and/or use social information.

  12. An update on psoriasis and metabolic syndrome: A meta-analysis of observational studies.

    Full Text Available The relationship between psoriasis and metabolic syndrome is not well understood. Though multiple epidemiologic studies have suggested a link between psoriasis and metabolic syndrome, there is a lack of a comprehensive meta-analysis synthesizing the results of all available observational studies to date. In this meta-analysis, we examined global data on the relationship between psoriasis and odds of metabolic syndrome by searching for studies published between 1946-2016. Specifically, we analyzed the results from 35 observational studies from 20 countries with 1,450,188 total participants, of which 46,714 were psoriasis patients. The pooled odds ratio based on random effects analysis was 2.14 (95% CI 1.84-2.48. Publication bias was present, as evidenced by an Egger test and graphical visualization through a funnel plot (p = 0.001. Based on this comprehensive meta-analysis, psoriasis patients have higher odds of having metabolic syndrome when compared with the general population.

    Full Text Available AIM: To observe the effect of 23G micro invasive vitrectomy in treating Terson syndrome. METHODS: Six cases(11 eyesof Terson syndrome with severe vitreous hemorrhage were performed 23G micro invasive vitrectomy since conservative treatment did not show effect on them. Membrane peeling and silicone oil tamponade were applied according to the retinal conditions. We observed the postoperative visual acuity(VA, retina and complications. RESULTS: All the cases had obvious improvement of postoperative VA,in which 8 eyes in 11(73%was better than 0.5. The postoperative VA of one eye(9%were less than 0.1 because of pre-existing proliferative vitreoretinal diseases and retinal detachment.CONCLUSION: 23G micro invasive vitrectomy is an effective approach in treating Terson syndrome. Most of the cases indicate good visual outcome. However, the cases with severe proliferation have poor outcome. We recommend performing an early 23G micro invasive vitrectomy for the failure of conservative treatment in Terson syndrome.

    Recent models on parenting propose different roles for fathers and mothers in the development of child anxiety. Specifically, it is suggested that fathers' challenging parenting behavior, in which the child is playfully encouraged to push her limits, buffers against child anxiety. In this longitudinal study, we explored whether the effect of challenging parenting on children's social anxiety differed between fathers and mothers. Fathers and mothers from 94 families were separately observed with their two children (44 % girls), aged 2 and 4 years at Time 1, in three structured situations involving one puzzle task and two games. Overinvolved and challenging parenting behavior were coded. Child social anxiety was measured by observing the child's response to a stranger at Time 1, and half a year later at Time 2, and by parental ratings. In line with predictions, father's challenging parenting behavior predicted less subsequent observed social anxiety of the 4-year-old child. Mothers' challenging behavior, however, predicted more observed social anxiety of the 4-year-old. Parents' overinvolvement at Time 1 did not predict change in observed social anxiety of the 4-year-old child. For the 2-year-old child, maternal and paternal parenting behavior did not predict subsequent social anxiety, but early social anxiety marginally did. Parent-rated social anxiety was predicted by previous parental ratings of social anxiety, and not by parenting behavior. Challenging parenting behavior appears to have favorable effects on observed 4-year-old's social anxiety when displayed by the father. Challenging parenting behavior emerges as an important focus for future research and interventions.

    We report high resolution observations from the Solar Dynamics Observatory/Atmospheric Imaging Assembly (SDO/AIA) of intensity oscillations in a hot, T ∼ 8-10 MK, loop. The AIA images show a large coronal loop that was rapidly heated following plasma ejection from one of the loop's footpoints. A wave-like intensity enhancement, seen very clearly in the 131 and 94 Å channel images, propagated ahead of the ejecta along the loop, and was reflected at the opposite footpoint. The wave reflected four times before fading. It was only seen in the hot, 131 and 94 Å channels. The characteristic period and the decay time of the oscillation were ∼630 and ∼440 s, respectively. The phase speed was about 460-510 km s{sup –1} which roughly matches the sound speed of the loop (430-480 km s{sup –1}). The observed properties of the oscillation are consistent with the observations of Dopper-shift oscillations discovered by the Solar and Heliospheric Observatory/Solar Ultraviolet Measurement of Emitted Radiation and with their interpretation as slow magnetoacoustic waves. We suggest that the impulsive injection of plasma, following reconnection at one of the loop footpoints, led to rapid heating and the propagation of a longitudinal compressive wave along the loop. The wave bounces back and forth a couple of times before fading.

    Full Text Available Abstract Background It has been recently demonstrated that serum uric acid (UA is associated with metabolic syndrome (MetS or its related clinical indications based on cross-sectional or prospective cohort studies. Nonetheless, due to the fact that UA level constantly fluctuates from time to time even for the person, using a single measure of UA level at baseline of those studies may not be sufficient for estimating the UA-Mets association. Methods To further estimate this time-dependent association, we fitted a generalized estimating equation (GEE regression model with data from a large-scale 6-year longitudinal study, which included 2222 participants aged > =25 years with an average of 3.5 repeated measures of UA per person in the Health Management Center of Shandong Provincial Hospital, Shandong, China. Results After adjusting for other potential confounding factors (i.e., total cholesterol, low-density lipoprotein, it was verified that time-dependent UA level was an independent risk factor for MetS (OR = 1.6920, p  Conclusions Serum UA level may serve as an important risk factor of MetS. Additionally, our study suggested that UA level be an independent risk factor to obesity, hypertension and dyslipidemia, but a protective factor to hyperglycemia. These findings are concordant with results from other studies on Asian populations, and jointly provide a basis to further develop a risk assessment model for predicting MetS using UA levels and other factors in China.

    Nearly 60% of patients who are intubated in intensive care units (ICUs) experience dysphagia after extubation, and approximately 50% of them aspirate. Little is known about dysphagia recovery time after patients are discharged from the hospital. To determine factors associated with recovery from dysphagia symptoms after hospital discharge for acute respiratory distress syndrome (ARDS) survivors who received oral intubation with mechanical ventilation. This is a prospective, 5-year longitudinal cohort study involving 13 ICUs at four teaching hospitals in Baltimore, Maryland. The Sydney Swallowing Questionnaire (SSQ), a 17-item visual analog scale (range, 0-1,700), was used to quantify patient-perceived dysphagia symptoms at hospital discharge, and at 3, 6, 12, 24, 36, 48, and 60 months after ARDS. An SSQ score greater than or equal to 200 was used to indicate clinically important dysphagia symptoms at the time of hospital discharge. Recovery was defined as an SSQ score less than 200, with a decrease from hospital discharge greater than or equal to 119, the reliable change index for SSQ score. Fine and Gray proportional subdistribution hazards regression analysis was used to evaluate patient and ICU variables associated with time to recovery accounting for the competing risk of death. Thirty-seven (32%) of 115 patients had an SSQ score greater than or equal to 200 at hospital discharge; 3 died before recovery. All 34 remaining survivors recovered from dysphagia symptoms by 5-year follow-up, 7 (23%) after 6 months. ICU length of stay was independently associated with time to recovery, with a hazard ratio (95% confidence interval) of 0.96 (0.93-1.00) per day. One-third of orally intubated ARDS survivors have dysphagia symptoms that persist beyond hospital discharge. Patients with a longer ICU length of stay have slower recovery from dysphagia symptoms and should be carefully considered for swallowing assessment to help prevent complications related to dysphagia.

    Adherence to the Mediterranean diet (MedDiet) has been proposed to reduce the risk of metabolic syndrome (MetS), but the association of the diet on MetS in non-Mediterranean populations remains unclear. The aim of this study was to investigate whether adherence to the MedDiet is related to the incident MetS and its components during a 3-year follow-up among Iranian adults. Longitudinal associations between the MedDiet and MetS components were investigated on 2241 adults, aged 18 - 74 years, without type 2 diabetes selected from participants of the Tehran lipid and glucose study (TLGS). The association between the MedDiet and MetS incidence was also examined in 1661 participants, free of Mets at baseline. Adherence to the MedDiet was assessed using the traditional Mediterranean diet score (MDS) and a recently posteriori adaptation of the MDS of Sofi et al. (Sofi-MDS). MetS was defined according to the recent interim consensus. After adjusting for potential confounders, neither higher MDS nor higher Sofi-MDS were significantly associated with the mean values of MetS components and the risk of metabolic abnormalities incidence after 3 years follow-up. During the 3 years of follow-up, 246 developed MetS were identified. In multivariable model, the adjusted odds ratio (OR) of developing MetS did not differ significantly in participants with the highest tertile of the MDS (OR (95% CI): 0.88 (0.62 - 1.23)) or sofi-MDS (OR (95% CI):1.12 (0.77 - 1.62)) compared to those in the lowest tertiles. Adherence to the MedDiet, according to MDS and Sofi-MDS, may not predict MetS components and MetS incidence after 3 years of follow-up in Iranian adult populations.

    Obesity is common in young women, increasing insulin resistance (IR) and worsening pregnancy complications, including gestational diabetes (GDM). Women with polycystic ovary syndrome (PCOS) are commonly obese, which aggravates the severity of PCOS clinical expression. Relationships between these common insulin-resistant conditions, however, remain unclear. We conducted a secondary analysis of the Australian Longitudinal Study on Women's Health (ALSWH) database, including data from 8009 women aged 18-36 years across six surveys. We used latent-curve growth modelling to identify distinct body mass index (BMI) trajectories and multinomial logistic regression to explore sociodemographic and health variables characterizing BMI group membership. Logistic regression was used to assess independent risk of GDM. A total of 662 women (8.29%, 95% CI 7.68-8.89) reported PCOS. Three distinct BMI trajectories emerged, namely low stable (LSG) (63.8%), defined as an average trajectory remaining at ~25 kg/m(2); moderately rising (MRG) (28.8%), a curvilinear trajectory commencing in a healthy BMI and terminating in the overweight range; and high-rising (HRG) (7.4%), a curvilinear trajectory starting and terminating in the obese range. A high BMI in early reproductive life predicted membership in higher trajectories. The HRG BMI trajectory was independently associated with GDM (OR 2.50, 95% CI 1.80-3.48) and was a stronger correlate than PCOS (OR 1.89, 95% CI 1.41-2.54), maternal age, socioeconomic status, or parity. Our results suggest heterogeneity in BMI change among Australian women of reproductive age, with and without PCOS. Reducing early adult life weight represents an ideal opportunity to intervene at an early stage of reproductive life and decreases the risk of long-term metabolic complications such as GDM.

    A system with an adult discrimination IC card "taspo" was introduced in 2008 to prevent minors from purchasing cigarettes in Japan. This study aimed to elucidate the short-term change in smoking behavior among a cohort of high school students through the introduction of the taspo system. We conducted a questionnaire survey in students at one high school in the metropolitan area of Japan in 2008. In this area, the taspo system was introduced on July 1, and the survey was conducted before and after its introduction (June and September). Change in smoking behavior was examined by linking the two questionnaires using a unique identification number for each participant. The questionnaire included basic characteristics, smoking-related behavior, and means of obtaining tobacco. Of 133 students, 123 (response rate 84.7%) completed the before and after questionnaire forms and could be linked. The smoking rate was 22.8% in June and 25.2% in September, with no statistically significant change. Vending machines were the major means of obtaining tobacco in June, while the use of cigarette shops and supermarkets increased after the introduction of taspo. The introduction of taspo hardly influenced underage smoking behavior during the observation period in our study subjects. The only significant change was in the means of obtaining tobacco. To prevent underage smoking, the importance of comprehensive restriction of the procurement route was suggested.

    Parents with past and current eating disorders (ED) have been shown to report troubles nourishing their infants. This could increase the risk of infant feeding problems linked to maternal anxiety and depression. It is not clear how mothers' eating difficulties before pregnancy and at the time of birth can affect infant's feeding. We aimed to specify the impact of eating disorders on mothers' adaptation and sensitivity to their offspring during feeding, by comparing a population of mothers with eating disorders and controls. Twenty-eight women agreed to participate in interviews and filmed mother-baby interactions. Pregnant women consulting at an obstetric unit for care follow-up were screened and tested for symptoms of eating disorders with the EDE-Q Questionnaire (Eating Disorders Examination Questionnaire) and the EDE Interview (Eating Disorders Examination Interview). Infant functional troubles and mothers' sensitivity were investigated through the Symptom Check List. Reciprocal adaptation during feeding with their new-borns was filmed and analysed with the Chatoor Infant Feeding Scale. Before pregnancy, two women suffered from anorexia, three suffered from bulimia, three had binge eating symptoms and two were diagnosed with EDNOS (Eating Disorders Not Otherwise Specified). Mothers suffering from ED tended to show more difficult interactive patterns in terms of dyadic reciprocity when feeding their babies compared with mothers with no symptoms of eating disorders. In the interviews, other than the behavioural data gathered, ED mothers expressed feeling more dissatisfaction and uneasiness during feeding. Pregnancy seems to be an useful period for interviewing women on eating disorders, allowing for the design and implementation of prevention programmes based on mothers' narratives and infant/mother observations and treatment.

    Patients' preferences and expectations should be taken into account in treatment decision making in the last phase of life. Shared decision making (SDM) is regarded as a way to give the patient a central role in decision making. Little is known about how SDM is used in clinical practice in advanced cancer care. To examine whether and how the steps of SDM can be recognized in decision making about second- and third-line chemotherapy. Fourteen advanced cancer patients were followed over time using face-to-face in-depth interviews and observations of the patients' out-clinic visits. Interviews and outpatient clinic visits in which treatment options were discussed or decisions made were transcribed verbatim and analysed using open coding. Patients were satisfied with the decision-making process, but the steps of SDM were barely seen in daily practice. The creation of awareness about available treatment options by physicians was limited and not discussed in an equal way. Patients' wishes and concerns were not explicitly assessed, which led to different expectations about improved survival from subsequent lines of chemotherapy. To reach SDM in daily practice, physicians should create awareness of all treatment options, including forgoing treatment, and communicate the risk of benefit and harm. Open and honest communication is needed in which patients' expectations and concerns are discussed. Through this, the difficult process of decision making in the last phase of life can be facilitated and the focus on the best care for the specific patient is strengthened. © 2015 The Authors.

    To identify changes in choroidal thickness (CT) and all retinal layers of diabetic patients without diabetic retinopathy (DR) after 1 year of follow-up. Prospective observational cohort study. Overall, 125 diabetic patients without DR were included. Two visits were scheduled: the first visit (V1) and a second visit after 12 months (V2). At both visits, patients received a complete ophthalmologic evaluation that included OCT. Each retinal layer thickness was calculated for 9 ETDRS sectors, and CT was measured at 13 locations. Generalized linear mixed-effects models were used. Of the 125 patients, 103 completed the study, and 9 of the 103 developed DR (8.7%). CT was significantly higher at V2 than at V1, with an average value of 10-17 μm at almost half the locations (500, 1000, and 1500 μm temporal; 500 and 1000 μm nasal; and 1000 μm superior to the fovea) (P retinopathy was negatively associated with overall RT (central, S3, T3, I3, and N3 sectors, P = .004-.024) and the thickness of the ONL (T6 and I6 sectors, P = .007 and P = .009) and photoreceptor layer (N6 sector, P = .038). The presence of DR decreased the overall RT by 13.04-16.63 μm. Diabetic patients without DR showed a thicker choroid and a thinner retina, particularly in inner layers, after 1 year of follow-up. These structural changes may correspond to the early neurodegenerative phase of DR. Copyright © 2016 Elsevier Inc. All rights reserved.

    The diagnostic evidence on clinical diseases and theoretic basis of moving cupping therapy were ex- plored in the paper. By the observation of the local reaction, such as skin appearance and color, the affected location, duration of sickness and nature of disease were judged. Different moving cupping methods were selected for different disorders. It was discovered that the property of syndromes should be recognized by the palpation on skin and muscle in the moving cupping therapy so that the pathogenesis and treating principle could be carefully determined. The moving cupping therapy is the important component of body surface therapy. Skin reaction observation and syndrome differentiation is the essential guidance of the moving cupping therapy.

    Lanreotide Autogel/Depot effectively controls symptoms in patients with carcinoid syndrome associated with neuroendocrine tumours. Data on patient-reported outcomes are sparse. To evaluate the effect of lanreotide on patient-reported outcomes (PROs) with carcinoid syndrome. This was an international, open-label, observational study of adults with neuroendocrine tumours and history of diarrhoea, receiving lanreotide for >3 months for relief of carcinoid syndrome symptoms. The primary PRO measure was satisfaction with diarrhoea control. Secondary PRO measures included severity, change in symptoms and impact on daily life of diarrhoea; and patient satisfaction with flushing control. Of 273 patients enrolled, 76% were 'completely' or 'rather' satisfied with diarrhoea control; 79% reported improvement in diarrhoea with lanreotide. The proportion of patients with 'mild', 'minimal', or 'no diarrhoea' increased from 33% before treatment to 75% during treatment; 75% were unconcerned about the impact of diarrhoea on daily life. Satisfaction with flushing control amongst patients with significant flushing at treatment initiation was 73%. Lanreotide treatment was associated with improvements in symptoms as well as a range of PROs in patients with neuroendocrine tumours and carcinoid syndrome (ClinicalTrials.gov: NCT01234168).

    The aim of the study was to assess the applicability of an algorithm predicting 10-year cardiovascular disease (CVD) generated in the setting of the Framingham Heart Study to a real-life, contemporary Italian cohort of HIV-positive subjects. The study was an observational longitudinal cohort study. The probability for 10-year CVD events according to the Framingham algorithm was assessed in 369 consecutive HIV-positive participants free from overt CVD enrolled in 2004, who were followed for a median of 10.0 years (interquartile range, 9.1-10.1). Cardiovascular events included myocardial infarction, hospitalized heart failure, revascularized angina, sudden cardiac death, stroke, peripheral arterial disease. Over 3097 person-years of observation, we observed a total of 34 CVD events, whereas Framingham algorithm predicted the occurrence of 34.3 CVD events. CVD event rate was 11.0/1000 person-years of follow-up. In a receiver operating characteristics curve analysis, Framingham risk equation showed an excellent predictive value for incident CVD events (c-statistics, 0.83; 95% confidence interval, 0.76-0.90). In a multivariable Cox analysis, age, smoking and diabetes were independent predictors of CVD events. All-cause death rate was 20.0/1000 person-years of follow-up (n = 62 deaths). Causes of death included liver diseases (18), malignancies (14), AIDS-related (11); cardiovascular (9) and others (10). In a Cox analysis, age, AIDS diagnosis and chronic hepatitis were independent predictors of death. Observed CVD events in HIV-infected patients were well predicted by Framingham algorithm. Established major CVD risk factors are the strongest determinants of CVD morbidity in an Italian contemporary cohort of HIV-positive subjects. Interventions to modify traditional risk factors are urgently needed in HIV people.

    Full Text Available Abstract Background Near term infants are a main part of preterms. They are at higher risk for mortality and morbidity than term infants and could show a quite different development of tone and reflexes from them. The aim of the present study was to describe longitudinally, in a large sample of healthy near term infants, the development of the forward parachute reaction (FPR and its correlation with the age of acquisition of independent walking. Methods The assessment of FPR (as absent, incomplete or complete was performed at 3, 6, 9, 12 months of corrected age in 484 infants, with a gestational age between 35.0 and 36.9 weeks. The age of acquisition of independent walking was monitored until its appearance. A correlation analysis was done between the age of walking and the acquisition of a complete or incomplete FPR, using the Spearman Rank correlation. The Mann-Withney U test was used to identify significant gestational age differences for the age of FPR appearance. Results Most of infants had a two-step development pattern. In fact, they showed at first an incomplete and then a complete FPR, which was observed more frequently at 9 months. An incomplete FPR only, without a successive maturation to a complete FPR, was present in the 21% of the whole sample. Infants with a complete FPR walked at a median age of 13 months, whereas those with an incomplete FPR only walked at a median age of 14 months. Conclusion We identified two groups within our sample of near term infants. The first group showed a progressive maturation of FPR, whereas the second one was characterised by the inability to get a complete pattern, within the one year observation's period. Furthermore, we observed a trend toward a delayed acquisition of independent walking in the latter group of infants.

    to controls, parallel and perpendicular diffusivity decreased in patients and were most pronounced in the patients with persisting tics compared to those with remission. The findings suggest that the development of the brain in patients with remission resembles the normal development more than in patients...... with persistent tics. This could reflect a change in brain structure or compensatory mechanisms in the brain.......There is evidence that cortico-striato-thalamo-cortical pathways are involved in Tourette syndrome.

  12. Brief clinical report: prune belly syndrome: observations supporting the hypothesis of abdominal overdistention.

    Burton, B K; Dillard, R G

    1984-03-01

    We report on an infant with the prune belly syndrome who was unusual in that the typical manifestations of the disorder were accompanied by an anterior abdominal wall defect. We speculate that this defect may have occurred as a result of splitting of the abdominal wall secondary to massive bladder dilatation and stretching of the abdominal muscles. An alternative explanation is that the defect may have been the result of secondary pressure necrosis from stretching forces or from contact with another structure, such as the cervix. This case lends further support to the hypothesis that bladder distention with overdistention of the abdomen may be the primary event leading to the findings observed in the prune belly syndrome.

    Clinical symptoms of patellar subluxation syndrome associated with pain were investigated for 24 knees of 20 patients, and the state of patella dislocation was observed by CT-scan. The patients had high incidence of an apprehension sign, showing their fear of patellar luxation. Many of them complained of patello-femoral joint pain due to chondromalacia patellae. In order to derive patellar subluxation, the method of CT-Q-contraction was carried out at the extended position of the patellar joint. In patients with patellar subluxation syndrome, the rate of shift in the diseased side was significantly higher than that of the other side, suggesting decreased muscular strength of the musculus vastus of the diseased side. Improvement of the symptoms was seen in all except one of 12 knees operated by the combined method of Green's method with Blauth's more than 6 months before. Availability of this operation was verified by the CT-Q-contraction.

    There is controversy whether congenital foot abnormalities are true risk factors for pathological dysplasia of the hip. Previous United Kingdom screening guidelines considered congenital talipes equinovarus (CTEV) to be a risk factor for hip dysplasia, but present guidelines do not. We assessed the potential relationship between pathological dysplasia of the hip and fixed idiopathic CTEV. We present a single-centre 21-year prospective longitudinal observational study. All fixed idiopathic CTEV cases were classified (Harrold and Walker Types 1 to 3) and the hips clinically and sonographically assessed. Sonographic Graf Type III, IV and radiological irreducible hip dislocation were considered to be pathological hip dysplasia. Over 21 years there were 139 children with 199 cases of fixed idiopathic CTEV feet. Sonographically, there were 259 normal hips, 18 Graf Type II hips, 1 Graf Type III hip and 0 Graf Type IV hip. There were no cases of radiological or sonographic irreducible hip dislocation. Fixed idiopathic CTEV should not be considered as a significant risk factor for pathological hip dysplasia. This conclusion is in keeping with the current newborn and infant physical examination guidelines in which the only risk factors routinely screened are family history and breech presentation. Our findings suggest CTEV should not be considered a significant risk factor in pathological dysplasia of the hip. ©2014 The British Editorial Society of Bone & Joint Surgery.

    Outcomes important to patients are those that are relevant to their well-being, including quality of life, morbid endpoints, and death. These outcomes often occur over the longterm and can be identified in prospective longitudinal observational studies (PLOS). There are no standards for which outcome domains should be considered. Our overarching goal is to identify critical longterm outcome domains for patients with rheumatic diseases, and to develop a conceptual framework to measure and classify them within the scope of OMERACT Filter 2.0. The steps of this initiative primarily concern rheumatoid arthritis (RA) and include (1) performing a systematic review of RA patient registries and cohorts to identify previously collected and reported outcome domains and measurement instruments; (2) developing a conceptual framework and taxonomy for identification and classification of outcome domains; (3) conducting focus groups to identify domains considered critical by patients with RA; and (4) surveying patients, providers, and researchers to identify critical outcomes that can be evaluated through the OMERACT filter. In our initial evaluation of databases and registries across countries, we found both commonalities and differences, with no clear standardization. At the initial group meeting, participants agreed that additional work is needed to identify which critical outcomes should be collected in PLOS, and suggested several: death, independence, and participation, among others. An operational strategy for the next 2 years was proposed. Participants endorsed the need for an initiative to identify and evaluate critical outcome domains and measurement instruments for data collection in PLOS.

    The understanding of palatine vault growth in normal subjects is important to orthodontists. The aim of this study was to evaluate three dimensional (3D) longitudinal changes in the palatal vault from 6 to 14 years of age. Complete dental stone casts were biennially prepared for 50 subjects (25 girls and 25 boys) followed up from 6 to 14 years of age. Virtual casts were constructed using 3D laser scanning and reconstruction software. The reference gingival plane was constructed. The palatal heights were measured from a total of 12 quadrisectional points between the most gingival points of the palatal dentogingival junctions from the canine to the first molar. In addition, the palatal heights were measured from a total of 12 lateral and medial endpoints of the palatine rugae. The measurement changes over time were analyzed using a mixed-effect analysis. There were significant annual increases in all of the variables related to palatal height. However, the individual random variability at baseline was quite large. There was no significant sexual dimorphism in the linear measurements or in the annual increases as fixed effects in the model. During the observation period, increases in palatal vault height were significant in all regions. The growth pattern seemed to differ between genders even though it was not significant. More elaborate methodology is necessary to gain a better understanding of 3D palatal growth.

    Understanding the dynamic disease process is vital in early detection, diagnosis, and measuring progression. Continuous-time Markov chain (CTMC) methods have been used to estimate state-change intensities but challenges arise when stages are potentially misclassified. We present an analytical likelihood approach where the hidden state is modeled as a three-state CTMC model allowing for some observed states to be possibly misclassified. Covariate effects of the hidden process and misclassification probabilities of the hidden state are estimated without information from a 'gold standard' as comparison. Parameter estimates are obtained using a modified expectation-maximization (EM) algorithm, and identifiability of CTMC estimation is addressed. Simulation studies and an application studying Alzheimer's disease caregiver stress-levels are presented. The method was highly sensitive to detecting true misclassification and did not falsely identify error in the absence of misclassification. In conclusion, we have developed a robust longitudinal method for analyzing categorical outcome data when classification of disease severity stage is uncertain and the purpose is to study the process' transition behavior without a gold standard.

    This 20-year prospective longitudinal study focuses on the contribution of mastery motivation and self-regulation to adult outcomes for individuals with Down syndrome. In earlier phases of the research, 25 participants completed measures of cognitive ability, mastery motivation and self-regulation in childhood (4 to 6 years) and adolescence (11 to 15 years). In the adult phase reported here, self-determination and adaptive behavior were assessed in 21 of the original participants at age 23 to 26 years. Mastery motivation and self-regulation made unique contributions to adult outcomes, over and above the effects of cognitive ability. The findings provide powerful evidence about the important role of child and adolescent mastery motivation and self-regulation for the adult lives of individuals with Down syndrome.

    In Ethiopia, information regarding highland malaria transmission is scarce, and no report has been presented from Butajira highland so far whether the appearance of malaria in the area was due to endemicity or due to highland malaria transmission. Thus this study aimed to determine the presence and magnitude of malaria transmission in Butajira. For parasitological survey, longitudinal study was conducted from October to December 2006. The entomological surveys were done from October to December 2006 and continued from April to May 2007. Both parasitological and entomological surveys were done using standard procedures. The parasitological result in all the survey months (October-December) showed an overall detection rate of 4.4% (48/1082) (CI 95%; 3.2-5.7%) malaria parasite. Among infected individuals, 32 (3.0%) of the infection was due to Plasmodium vivax and the rest 16 (1.5%) were due to Plasmodium falciparum. The highest prevalence 39(3.6%) of the parasite was observed in age groups of above 15 years old. Among the total tested, 25(2.3%) of males and 23(2.1%) of females had malaria infection. Among tested individuals, 38(5.3%) and 10 (2.7%) of infection was occurred in Misrak-Meskan (2100 m a.s.l) and Mirab-Meskan (2280 m a.s.l), respectively which was statistically significant (X2=3.72, P0.05). The entomological survey showed a collection of 602 larvae and 80 adult Anopheles. Anopheles christyi was the dominant species both in the first (45.3%) and in the second (35.4%) surveys; where as, Anopheles gambiae sensu lato comprised 4.7% and 14.6%, in the first and second surveys, respectively. Anopheles gambiae s.l comprises 55% of the adult collection, and both species were collected more from outdoors (57.5%). The number of An. christyi was higher in Mirab-Meskan (58. 3%) than Misrak-Meskan (41.7%) (Prisk of malaria and its control programme in the area must be given adequate attention to minimize potential epidemics.

    Background Patients with acute coronary syndromes (ACS) are at increased risk of further acute cardiac events. Secondary prevention aims to decrease morbidity and mortality post-ACS. Depression is related to increased risk in this population, and to poorer secondary prevention activities. However, lengthy depression assessment techniques preclude depression assessment in routine care. The present study investigated the relationship of briefly-assessed depression with secondary prevention outcomes one year post-ACS. Methods Following ethics committee approval, hospitals recruited patients for a national survey of ACS. Consenting patients with ACS completed a brief depression scale during hospitalisation. The predictive validity of two brief scales was independently assessed, with groups combined for the overall sample. Participants then completed a one-year longitudinal follow-up postal survey of secondary prevention activities. Results The response rate for follow-up was 86% (n = 681). Proportions taking anti-platelet (88% v 87%; p = 0.334) and lipid-lowering (83% v 84%; p = 0.437) therapies remained unchanged. Prevalence of smoking (40% v 22%; p smoked (20 v 10; p 0.05), but did predict continuation of smoking (OR = 2.3, 95% CI 1.3–4.0, p = 0.003), a higher (above median) number of general practitioner visits (OR = 2.1, 95% CI 1.3–3.4, p = 0.005), failure to return to work (OR = 0.4, 95% CI 0.2–0.8, p = 0.015), and not feeling better (OR = 0.6, 95% CI 0.3–1.0, p = 0.05) at one year. Conclusion Rapid depression assessment can be used to help identify patients with ACS at risk of a range of poorer secondary prevention outcomes. The results provide support for the routine screening of depression in acute settings. Strategies to increase rates of smoking cessation, return to work, general well-being and decrease health service use by depressed patients may need to incorporate some element of treatment for depression.

Prevalence of smoking (40% v 22%; p 0.05, but did predict continuation of smoking (OR = 2.3, 95% CI 1.3–4.0, p = 0.003, a higher (above median number of general practitioner visits (OR = 2.1, 95% CI 1.3–3.4, p = 0.005, failure to return to work (OR = 0.4, 95% CI 0.2–0.8, p = 0.015, and not feeling better (OR = 0.6, 95% CI 0.3–1.0, p = 0.05 at one year. Conclusion Rapid depression assessment can be used to help identify patients with ACS at risk of a range of poorer secondary prevention outcomes. The results provide support for the routine screening of depression in acute settings. Strategies to increase rates of smoking cessation, return to work, general well-being and decrease health service use by depressed patients may need to incorporate some element of treatment for depression.

    There are few longitudinal studies on sick building syndrome (SBS), which include ocular, nasal, throat, and dermal symptoms, headache, and fatigue. We studied the associations between selected microbial components, fungal DNA, furry pet allergens, and incidence and remission of SBS symptoms in schools in Taiyuan, China. The study was based on a two-year prospective analysis in pupils (N = 1143) in a random sample of schools in China. Settled dust in the classrooms was collected by vacuum cleaning and analyzed for lipopolysaccharide (LPS), muramic acid (MuA), and ergosterol (Erg). Airborne dust was collected in Petri dishes and analyzed for cat and dog allergens and fungal DNA. The relationship between the concentration of allergens and microbial compounds and new onset of SBS was analyzed by multi-level logistic regression. The prevalence of mucosal and general symptoms was 33% and 28%, respectively, at baseline, and increased during follow-up. At baseline, 27% reported at least one symptom that improved when away from school (school-related symptoms). New onset of mucosal symptoms was negatively associated with concentration of MuA, total LPS, and shorter lengths of 3-hydroxy fatty acids from LPS, C14, C16, and C18. Onset of general symptoms was negatively associated with C18 LPS. Onset of school-related symptoms was negatively associated with C16 LPS, but positively associated with total fungal DNA. In general, bacterial compounds (LPS and MuA) seem to protect against the development of mucosal and general symptoms, but fungal exposure measured as fungal DNA could increase the incidence of school-related symptoms. - Highlights: {yields} SBS symptoms increased during the two-year follow-up period in school children in Taiyuan, China {yields} We studied the associations between selected microbial components and incidence and remission of SBS symptoms. {yields} Bacterial compounds (LPS and MuA) seem to protect against the development of mucosal and general symptoms

    Insulin-like growth factor binding protein 1 (IGFBP-1) is a marker of insulin resistance. We hypothesized that IGFBP-1 is associated with the metabolic syndrome (MetS), which is related to insulin resistance. We examined 51 obese Caucasian children (mean age 12.1 ? 2.3, 55% male, mean body mass index [BMI] 31.8 ? 4.8 kg/m(2)). Anthropometrical markers, pubertal stage, hepatic ultrasound, waist circumference, blood pressure, fasting serum IGFBP-1, IGFBP-3, IGF-I, adiponectin, leptin, transaminases, glucose, insulin, triglycerides, and HDL-cholesterol concentrations were determined at onset and the end of the one-year lifestyle intervention. In contrast to IGF-I and IGFBP-3, IGFBP-1 correlated significantly to most parameters of the MetS in cross-sectional (waist circumference: r = -0.45, triglycerides: r = -0.29; insulin: r = -0.31; HOMA: r = -0.30) and longitudinal analyses (? triglycerides: r = ?0.22; ? Insulin: r = ?0.25; ? HOMA: r = ?0.62). The association between changes of HOMA and changes of IGFBP-1 was stronger than the associations between changes of leptin or adiponectin, and changes of HOMA. The risk for the MetS was inversely related to IGFBP-1 levels (odds ratio:-0.05 per additional IGFBP-1 unit; 95% confidence interval: -0.08 up to -0.02; p = 0.019) in a multiple logistic regression analyses adjusted to BMI, pubertal stage, age, and gender. The nine obese children with the MetS had significantly lower IGFBP-1 levels (1.6 ? 1.3 ngm/l) than the 42 obese children without the MetS (4.0 ? 3.8 ng/ml). The eleven obese children with fatty liver assessed by ultrasound had significantly lower IGFBP-1 levels (1.5 ? 1.3 ngm/l) than the 40 obese children without fatty liver (4.2 ? 4.1 ng/ml). The strong relationships between IGFBP-1, insulin resistance, and the MetS suggest that IGFBP-1 might be a promising marker for these entities in obesity. This study is registered at clinicaltrials.gov (NCT00435734).

    This study aimed at evaluating the sensitivity, specificity, reliability and repeatability of observer assessment of thermographic images taken from Complex Regional Pain Syndrome (CRPS) type 1. A computer program was developed to let observers rate the difference between randomly presented thermographic images of pairs of hands of individuals. The sensitivity and specificity, and potential learning effects were measured. Effects of the colours and rank number of the images were analysed. The sensitivity was 71% and the specificity 85%. The repeatability was 0.5267 and the reliability was 0.4967. No significant relation was found between the rank number and the rating. There was a significant correlation between the colour pallet and the rating (r = 0.76). Although the colour pallet used partly explained the variance in the rating scores, this study shows that observer assessment of thermographic images may distinguish between CRPS1 patients and healthy controls. However, the reliability and repeatability of this assessment was rather low.

    Full Text Available Several studies have shown that a poor vitamin D status may increase the risk of developing metabolic syndrome, which leaves the question whether improving one’s vitamin D status may reduce the risk for the syndrome. Here we investigate the effect of temporal changes in serum 25-hydroxyvitamin D (25(OHD concentrations on metabolic syndrome among Canadians enrolled in a preventive health program that promotes vitamin D supplementation. We accessed and analyzed data of 6682 volunteer participants with repeated observations on serum 25(OHD concentrations and metabolic syndrome. We applied logistic regression to quantify the independent contribution of baseline serum 25(OHD and temporal increases in serum 25(OHD to the development of metabolic syndrome. In the first year in the program, participants, on average, increased their serum 25(OHD concentrations by 37 nmol/L. We observed a statistical significant inverse relationship of increases in serum 25(OHD with risk for metabolic syndrome. Relative to those without improvements, those who improved their serum 25(OHD concentrations with less 25 nmol/L, 25 to 50 nmol/L, 50 to 75 nmol/L, and more 75 nmol/L had respectively 0.76, 0.64, 0.59, 0.56 times the risk for metabolic syndrome at follow up. These estimates were independent of the effect of baseline serum 25(OHD concentrations on metabolic syndrome. Improvement of vitamin D status may help reduce the public health burden of metabolic syndrome, and potential subsequent health conditions including type 2 diabetes and cardiovascular disease.

    We follow the eruption of two related intermediate filaments observed in Hα (from GONG) and EUV (from Solar Dynamics Observatory SDO/Atmospheric Imaging assembly AIA) and the resulting large-amplitude longitudinal oscillations of the plasma in the filament channels. The events occurred in and around the decayed active region AR12486 on 2016 January 26. Our detailed study of the oscillation reveals that the periods of the oscillations are about one hour. In Hα, the period decreases with time and exhibits strong damping. The analysis of 171 Å images shows that the oscillation has two phases: an initial long-period phase and a subsequent oscillation with a shorter period. In this wavelength, the damping appears weaker than in Hα. The velocity is the largest ever detected in a prominence oscillation, approximately 100 {km} {{{s}}}-1. Using SDO/HMI magnetograms, we reconstruct the magnetic field of the filaments, modeled as flux ropes by using a flux-rope insertion method. Applying seismological techniques, we determine that the radii of curvature of the field lines in which cool plasma is condensed are in the range 75–120 Mm, in agreement with the reconstructed field. In addition, we infer a field strength of ≥7 to 30 Gauss, depending on the electron density assumed, that is also in agreement with the values from the reconstruction (8–20 Gauss). The poloidal flux is zero and the axis flux is on the order of 1020 to 1021 Mx, confirming the high shear existing even in a non-active filament.

    Full Text Available Abstract Background In Ethiopia, information regarding highland malaria transmission is scarce, and no report has been presented from Butajira highland so far whether the appearance of malaria in the area was due to endemicity or due to highland malaria transmission. Thus this study aimed to determine the presence and magnitude of malaria transmission in Butajira. Methods For parasitological survey, longitudinal study was conducted from October to December 2006. The entomological surveys were done from October to December 2006 and continued from April to May 2007. Both parasitological and entomological surveys were done using standard procedures. Results The parasitological result in all the survey months (October-December showed an overall detection rate of 4.4% (48/1082 (CI 95%; 3.2-5.7% malaria parasite. Among infected individuals, 32 (3.0% of the infection was due to Plasmodium vivax and the rest 16 (1.5% were due to Plasmodium falciparum. The highest prevalence 39(3.6% of the parasite was observed in age groups of above 15 years old. Among the total tested, 25(2.3% of males and 23(2.1% of females had malaria infection. Among tested individuals, 38(5.3% and 10 (2.7% of infection was occurred in Misrak-Meskan (2100 m a.s.l and Mirab-Meskan (2280 m a.s.l, respectively which was statistically significant (X2 = 3.72, P Plasmodium species declined from October to December, the trend was non-significant (X2 for trend = 0.49, P > 0.05.

    The aim of the present study was to investigate the stability and longitudinal association between depression and smoking status within a community sample with type 2 diabetes (T2D) while controlling for sociodemographic and disease-related variables. Adults with T2D were recruited and agreed to be followed-up via random digit dialing for the Montreal Diabetes Health Study. At baseline, 1614 individuals were classified as never (n = 592), former (n = 690), light (≤10 cigarettes a day; n = 128) and moderate-heavy (11+ cigarettes a day; n = 204) smokers. Depression was assessed using the Patient Health Questionnaire-9 and individuals were classified as either "none" or having depression syndrome. Generalized estimating equations were used to test the association between depression syndrome and current smoking status while controlling for other demographic and health-related variables. Prevalence rates of smoking and depression showed mild to substantial agreement over time. Depression syndrome was significantly associated with moderate-heavy smoking in the fully adjusted model using cross-sectional (all four waves; odds ratio [OR] 1.46; 95% confidence interval [CI] 1.08-1.99; P Smoking and depression prevalence rates appear to be stable over time in our community sample with T2D. Moderate-heavy smoking is strongly associated with elevated depression, both in cross-sectional and longitudinal models. Persistent moderate-heavy smokers may be at increased risk of both physical and mental health complications. This burden is even greater for those with T2D. © 2014 Ruijin Hospital, Shanghai Jiaotong University School of Medicine and Wiley Publishing Asia Pty Ltd.

    Many of today's young adults with Down syndrome never had the opportunity to learn to read. However, an increasing number of children with Down syndrome are currently attending mainstream schools and being taught to read. As a consequence, it is now possible to systematically study reading development in children with Down syndrome. The aim of this study was to chart the development of reading, language, and memory skills in children with Down syndrome and to investigate the relationships between these abilities. Twenty-four children with Down syndrome aged between 4 and 12 were followed over two years and compared to 31 children matched for reading age, and 42 children of average reading ability, selected from the same mainstream classes as the children with Down syndrome. Standardised assessments were administered annually to obtain measures of reading, spelling, language, memory, and general intelligence. The children with Down syndrome had relatively advanced single word reading ability compared to their other cognitive skills. The reading progress of the children with Down syndrome did not differ significantly from that of the reading matched group even after two years. Different cognitive abilities were highly correlated with one another in all groups. However, after controlling for age, many of the partial correlations between reading and the other measures were reduced to non-significant levels. Most children with Down syndrome are capable of learning to read single words. However, there was no evidence over this two-year period to support the hypothesis that learning to read will help to enhance language and memory development in children with Down syndrome.

    The objective of the manuscript was to describe the natural history of complaints and disability in children diagnosed with joint hypermobility syndrome (JHS)/Ehlers-Danlos-hypermobility type (EDS-HT) and to identify the constructs that underlie functional decline. One hundred and one JHS/EDS-HT children were observed over 3 years and assessed at three time points on the following: functional impairments, quality of life, connective tissue laxity, muscle function, postural control and musculoskeletal and multi-systemic complaints. Cluster analysis was performed to identify subgroups in severity. Clinical profiles were determined for these subgroups, and differences were assessed by multivariate analysis of covariance. Mixed linear regression models were used to determine the subsequent trajectories. Finally, an exploratory factor analysis was used to uncover the underlying constructs of functional impairment. Three clusters of children were identified in terms of functional impairment: mild, moderately and severely affected. Functional impairment at baseline was predictive of worsening trajectories in terms of reduced walking distance and decreased quality of life (P ⩽ 0.05) over 3 years. Multiple interactions between the secondary outcomes were observed, with four underlying constructs identified. All four constructs (multi-systemic effects, pain, fatigue and loss of postural control) contributed significantly to disability (P ⩽ 0.046). Children diagnosed with JHS/EDS-HT who have a high incidence of multi-systemic complaints (particularly, orthostatic intolerance, urinary incontinence and diarrhoea) and poor postural control in addition to high levels of pain and fatigue at baseline are most likely to have a deteriorating trajectory of functional impairment and, accordingly, warrant clinical prioritization.

    The aim of this study was to identify aggressive event incidence rates in the inpatient psychiatric setting, describe characteristics of events and differences based on aggression target and type (verbal vs. physical). A longitudinal study was carried out of aggressive events identified by workers in four inpatient psychiatric units using the Staff Observation of Aggression Scale-Revised (SOAS-R) over 6 weeks. A total of 113 aggressive events were recorded resulting in a rate of 13.27 events per bed per year. Verbal aggression was demonstrated in 86 % and physical aggression in 57 % of events. Most events (70.8 %, n = 81) targeted a worker. Compared to other targets, workers were 3.4 times more likely to feel threatened (95 % CI 1.2-9.6, χ(2) = 5.08, p = 0.0242), and less likely to have a visible injury (OR 0.15, 95 % CI 0.04-0.6; χ(2) = 7.1, p = 0.0078). Event severity ranged from 0 to 21 with a mean of 9.5(SD = 5.1), with 20 % considered severe. Verbal events had lower mean severity of 6.5(SD = 3.8) versus physical events with a severity of 11.8(SD = 4.8; t = 6.5, df = 111, p < 0.0001). In 57.5 % of events there was no consequence to the victim. For most events (76 %) resolution included workers talking to the patient, while 54 % involved use of medication. Restrictive measures (physical hold, seclusion or physical restraint) were involved in 24.8 % of events. Aggression incidence was similar to incidence found in other studies. Workers were the target of most aggressive events and many were identified as having no understandable provocation. Further understanding of event characteristics will promote more effective prevention and management of aggressive events.

    Study Objectives: To investigate the association between sleep duration and semen parameters as well as reproductive hormone levels. Methods: We designed a cohort of male college students in Chongqing, China. A total of 796 subjects were recruited in 2013 and 656 (82.4%) were followed up in 2014. Each time, semen and peripheral blood samples were collected for semen quality and reproductive hormone measurement. Sleep duration was estimated by revised Munich Chronotype Questionnaire. In 2014, sleep quality was also measured by Pittsburgh Sleep Quality Index (PSQI). Results: There was a substantial inverse U-shaped association between sleep duration and two semen parameters (semen volume and total sperm number), with 7.0–7.5 h/day of sleep showing highest parameters. Either longer or shorter sleep was associated with decreased semen parameters in a dose-response manner (P = 0.002 and 0.001, respectively). Sleeping > 9.0 h was associated with a 21.5% (95% confidence interval 9.2, 32.2) reduction in semen volume and 39.4% (23.3, 52.1) reduction in total sperm number; sleeping ≤ 6.5 h was associated with 4.6% (−10.5, 22.3) and 25.7% (−1.2, 60.1) reduction. Increase of the two parameters was found in those who changed sleep duration toward 7.0–7.5 h/day from 2013 to 2014. The U-shaped association was independent from PSQI and was replicated in another dataset of 1,346 males. No association found between sleep duration and reproductive hormone. Conclusions: Either restricted or excessive sleep may impair semen quality. Further research is needed to validate this finding.

    Patients with complex regional pain syndrome (CRPS) display various abnormalities in central motor function, and their pain is intensified when they perform or just observe motor actions. In this study, we examined the abnormalities of brain responses to action observation in CRPS. We analyzed 3-T functional magnetic resonance images from 13 upper limb CRPS patients (all female, ages 31-58 years) and 13 healthy, age- and sex-matched control subjects. The functional magnetic resonance imaging data were acquired while the subjects viewed brief videos of hand actions shown in the first-person perspective. A pattern-classification analysis was applied to characterize brain areas where the activation pattern differed between CRPS patients and healthy subjects. Brain areas with statistically significant group differences (q CRPS impairs action observation by affecting brain areas related to pain processing and motor control. This article shows that in CRPS, the observation of others' motor actions induces abnormal neural activity in brain areas essential for sensorimotor functions and pain. These results build the cerebral basis for action-observation impairments in CRPS. Copyright © 2016 American Pain Society. Published by Elsevier Inc. All rights reserved.

  20. Patients with shoulder syndromes in general and physiotherapy practice: an observational study

    Science.gov (United States)

    2013-01-01

    Background Shoulder complaints are commonly seen in general practice and physiotherapy practice. The only complaints for which general practitioners (GPs) refer more patients to the physiotherapist are back and neck pain. However, a substantial group have persistent symptoms. The first goal of this study is to document current health care use and the treatment process for patients with shoulder syndromes in both general practice and physiotherapy practice. The second goal is to detect whether there are differences between patients with shoulder syndromes who are treated by their GP, those who are treated by both GP and physiotherapist and those who access physiotherapy directly. Methods Observational study using data from the Netherlands Information Network of General Practice and the National Information Service for Allied Health Care. These registration networks collect healthcare-related information on patient contacts including diagnoses, prescriptions, referrals, treatment and evaluation on an ongoing basis. Results Many patients develop symptoms gradually and 35% of patients with shoulder syndromes waited more than three months before visiting a physiotherapist. In 64% of all patients, treatment goals are fully reached at the end of physiotherapy treatment. In general practice, around one third of the patients return after the referral for physiotherapy. Patients with shoulder syndromes who are referred for physiotherapy have more consultations with their GP and are prescribed less medication than patients without a referral. Often, this referral is made at the first consultation. In physiotherapy practice, referred patients differ from self-referrals. Self-referrals are younger, they more often have recurrent complaints and their complaints are more often related to sports and leisure activities. Conclusions There is a fairly large group of patients with persistent symptoms. Early referral by a GP is not advised under current guidelines. However, in many

    This study investigated observers' intelligibility for the spoken output of an individual with Moebius syndrome (MoS) with and without visual cues. An audiovisual recording of the speaker's output was obtained for 50 Speech Intelligibility in Noise sentences consisting of 25 high predictability and 25 low predictability sentences. Stimuli were presented to observers under two conditions: audiovisual and audio only. Data were analyzed using a multivariate repeated measures model. OBSERVERS: Twenty students and faculty affiliated with the Department of Speech Pathology and Audiology at the University of Nevada, Reno. ANOVA mixed design revealed that intelligibility for the audio condition only was significantly greater than intelligibility for the audiovisual condition; and accuracy for high predictability sentences was significantly greater than accuracy for low predictability sentences. The compensatory substitutional placements for phonemes produced by MoS speakers may detract from the intelligibility of speech. This is similar to the McGurk-MacDonald effect, whereby an illusory auditory signal is perceived when visual information from lip movements does not match the auditory information from speech. It also suggests that observers use contextual clues, more than the acoustic signal alone, to arrive at the accurate recognition of the message of the speakers with MoS. Therefore, speakers with MoS should be counseled in the top-down approach of auditory closure. When the speech signal is degraded, predictable messages are more easily understood than unpredictable ones. It is also important to confirm the speaking partner's understanding of the topic before proceeding.

    Full Text Available During the preparatory work for the optical-replica synthesizer experiment in the free-electron laser FLASH at DESY, we were able to superimpose a short, approximately 200 fs long pulse from a frequency-doubled mode-locked erbium laser with titanium-sapphire amplifier and an approximately 20 ps long electron bunch in an undulator. This induces an energy modulation in a longitudinal slice of the electron bunch. A magnetic chicane downstream of the undulator converts the energy modulation into a density modulation within the slice that causes the emission of coherent optical transition radiation from a silver-coated silicon screen. Varying the relative timing between electron and laser, we use a camera to record two-dimensional images of the slices as a function of the longitudinal position within the electron bunch.

    Improvements in the treatment of coronary artery disease mean that an increasing number of patients survive acute cardiovascular events and live as outpatients with or without anginal symptoms. To determine the characteristics and management of contemporary outpatients with stable coronary artery disease in Western Europe, and to compare France with the other Western European countries. CLARIFY (prospeCtive observational LongitudinAl RegIstry oF patients with stable coronary arterY disease) is an international, prospective, observational, longitudinal study. Between November 2009 and July 2010, 32,954 adult outpatients with stable coronary artery disease (defined as a history of documented myocardial infarction [of >3 months], prior coronary revascularization, chest pain with myocardial ischaemia, or coronary stenosis of>50% proven by angiography) were enrolled in 45 countries. The demographics and management of CLARIFY patients enrolled in France were compared with those enrolled in other Western European countries (Austria, Belgium, Denmark, Germany, Greece, Ireland, Italy, Netherlands, Portugal, Spain, Switzerland and the UK). Of the 14,726 patients enrolled in Western Europe (mean age 66.2 [10.2] years; 79.6% male), 2432 (16.5%) were from France. The use of aspirin was lower in France than in other Western European countries (74.5% vs. 86.9%, respectively), whereas use of thienopyridines (48.5% vs. 21.7%), oral anticoagulants (12.3% vs. 9.0%) and lipid-lowering drugs (95.8% vs. 92.5%) was higher. Beta-blockers were used in 73% of both groups. Angina was less prevalent in France (6.3% vs. 15.5%) and French patients showed higher levels of physical activity than their counterparts in Western Europe. The management of patients with stable CAD in France appears favourable, with good adherence to guideline-based therapies, but there remains room for improvement in terms of symptom and risk factor control.

    It is controversial whether serum uric acid (SUA) is a risk factor for the prevalence of metabolic syndrome (MetS). The current study was designed to highlight the association of SUA and MetS and its components. Data on 3675 healthy male subjects, aged 17-88 years, were collected for the cross-sectional study. A representative sample of 2575 individuals who did not suffer from MetS at baseline was involved in the cohort study. A cox regression model was applied to evaluate causality for the 2- and 4-year large scale longitudinal study. In the cross-sectional analysis, SUA showed a statistically significant negative correlation with high-density lipoprotein cholesterol (HDL-c) and a positive correlation with blood pressure (BP), triglycerides (TG), waist circumference (WC), and body mass index (BMI) (all P<0.001). In longitudinal analysis, examining the risk of developing MetS, SUA concentrations (hazard ratios comparing fourth quartile to the first quartile of 1.75; 95% CI, 1.26-2.41) were positively associated with incident MetS after adjusted for age, blood pressure, glucose, TG, HDL-c, smoking, alcohol drinking and education. SUA is positively correlated with the prevalence of MetS. Increased SUA concentration may be an independent risk factor for MetS. Copyright © 2015. Published by Elsevier B.V.

    Experimental data indicate that sepsis influences the mitochondrial function and metabolism. We aim to investigate longitudinal bioenergetic, metabolic, hormonal, amino-acid, and innate immunity changes in children with sepsis. Sixty-eight children (sepsis, 18; systemic inflammatory response syndrome [SIRS], 23; healthy controls, 27) were enrolled. Plasma amino acids were determined by high-performance liquid chromatography (HPLC); flow-cytometry expressed as mean fluorescence intensity (MFI) of heat shock protein (HSP) levels from monocytes (m) and neutrophils (n); resistin, adiponectin, and extracellular (e) HSPs evaluated by ELISA; ATP levels in white blood cells by luciferase luminescent assay; lipid peroxidation products (TBARS) by colorimetric test; nitrite and nitrate levels by chemiluminescent assay; biliverdin reductase (BVR) activity by enzymatic assay; and energy-expenditure (EE) by E-COVX. Resistin, eHSP72, eHSP90α, and nitrate were longitudinally higher in sepsis compared with SIRS (pmetabolic pattern were repressed in sepsis compared with SIRS (pmetabolism, mHSP72, and induced resistin and adiponectin (pmetabolic-hormones and eHSP72/HSP90α, repression of bioenergetics and innate immunity, hypo-metabolism, and amino-acid kinetics changes discriminate sepsis from SIRS; malnutrition, hypo-metabolism, and persistently increased resistin and adiponectin are associated with poor outcome. © 2018 American Society for Parenteral and Enteral Nutrition.

    By using COSMIC (Constellation Observing System for Meteorology, Ionosphere, and Climate) satellite observations, and GITM (Global Ionosphere and Thermosphere Model) simulations, the altitudinal dependences of the longitudinal differences in electron densities Ne were studied at mid-latitudes for the first time. Distinct altitudinal dependences were revealed: (1) in the northern (southern) hemisphere, there were wave-1 variations mainly in the daytime in the altitudes below 180 km, but wave-2 (wave-1) variations over a whole day above 220 km; (2) a transition (or separation) layer occurred mainly in the daytime within 180 km and 220 km, showing reversed longitudinal variation from that at lower altitudes. Solar illumination was one of the plausible mechanisms for the zonal difference of Ne at lower altitudes. At higher altitudes both neutral winds and solar illumination played important roles. The neutral winds effects accounted for the longitudinal differences in Ne in the European-Asian sector. Neutral composition changes and neutral wind effects both contributed to the formation of the transition layer.

    The marijuana amotivational syndrome posits that cannabis use fosters apathy through the depletion of motivation-based constructs such as self-efficacy. The current study pursued a two-round design to rule out concomitant risk factors responsible for the connection from marijuana intake to lower general self-efficacy. College students (N = 505) completed measures of marijuana use, demographics (age, gender, and race), personality (extraversion, agreeableness, conscientiousness, openness, and neuroticism), other substance use (alcohol and tobacco), and general self-efficacy (initiative, effort, and persistence) in two assessments separated by a month. Hierarchical regression models found that marijuana use forecasted lower initiative and persistence, even after statistically ruling out 13 pertinent baseline covariates including demographics, personality traits, alcohol use, tobacco use, and self-efficacy subscales. A cross-lagged panel model involving initiative, effort, persistence, alcohol use, cigarette use, and marijuana use sought to unravel the temporal precedence of processes. Results showed that only marijuana (but not alcohol or tobacco) intake significantly and longitudinally prompted lower initiative and persistence. Furthermore, in the same model, the opposite temporal direction of events from lower general self-efficacy subscales to marijuana use was untenable. Findings provide partial support for the marijuana amotivational syndrome, underscore marijuana as a risk factor for decreased general self-efficacy, and offer implications and insights for marijuana prevention and future research.

    Full Text Available Evans syndrome (ES is a rare autoimmune disorder whose long-term follow-up characteristics are unknown. Patients under 18 at the time of diagnosis of a first autoimmune cytopenia have been included since 2004 in a national prospective observational cohort. In 2014, 156 children diagnosed between 1981 and 2014 with ES, were analyzed. The median age at initial cytopenia was 5.4 (0.2-17.2 years old. For 85 sequential cases, the median delay between the episodes of AIHA and ITP was 2.4 years (0.1–16.3. The median follow-up since ES diagnosis was 6.5 years (0.1-28.8. ES revealed underlying diseases in 10% of children; in 60% of patients, various associated immune manifestations were observed, and ES remained primary in 30%. Five-year ITP and AIHA relapse-free survival were respectively 25% and 61%. In all, 69% of children required one or more than one second-line immune treatment and 15 patients (10% died at a median age of 14.3 years (1.7-28.1.This national work provides the first consistent clinical description for ES and underscores the high percentage of associated immune manifestations, the long-term complications, and treatment toxicities. Current challenges include the identification of underlying genetic immune dysregulations and better characterization of subgroups of patients and of second-line therapy strategies.

    Rational and Objective: Dynamic contrast enhanced (DCE)-MRI has great potential to provide quantitative measure of inflammatory activity in rheumatoid arthritis. There is no current benchmark to establish the stability of signal in the joints of healthy subjects when imaged with DCE-MRI longitudinally, which is crucial so as to differentiate changes induced by treatment from the inherent variability of perfusion measures. The objective of this study was to test a pixel-by-pixel parametric map based approach for analysis of DCE-MRI (Dynamika) and to investigate the variability in signal characteristics over time in healthy controls using longitudinally acquired images. Materials and Methods: 10 healthy volunteers enrolled, dominant wrists were imaged with contrast enhanced 3T MRI at baseline, week 12, 24 and 52 and scored with RAMRIS, DCE-MRI was analysed using a novel quantification parametric map based approach. Radiographs were obtained at baseline and week 52 and scored using modified Sharp van der Heidje method. RAMRIS scores and dynamic MRI measures were correlated. Results: No erosions were seen on radiographs, whereas MRI showed erosion-like changes, low grade bone marrow oedema and low-moderate synovial enhancement. The DCE-MRI parameters were stable (baseline scores, variability) (mean ± st.dev); in whole wrist analysis, ME{sub mean} (1.3 ± 0.07, −0.08 ± 0.1 at week 24) and IRE{sub mean} (0.008 ± 0.004, −0.002 ± 0.005 at week 12 and 24). In the rough wrist ROI, ME{sub mean} (1.2 ± 0.07, 0.04 ± 0.02 at week 52) and IRE{sub mean} (0.001 ± 0.0008, 0.0006 ± 0.0009 at week 52) and precise wrist ROI, ME{sub mean} (1.2 ± 0.09, 0.04 ± 0.04 at week 52) and IRE{sub mean} (0.001 ± 0.0008, 0.0008 ± 0.001 at week 24 and 52). The Dynamic parameters obtained using fully automated analysis demonstrated strong, statistically significant correlations with RAMRIS synovitis scores. Conclusion: The study demonstrated that contrast enhancement does occur in

    Les syndromes microdélétionnels sont définis par la présence d’une anomalie chromosomique de taille mineure (inférieure à 5 mégabases) ou aneusomie segmentaire, décelable par cytogénétique moléculaire (FISH : Fluorescent in Situ Hybridization). Les syndromes microdélétionnels représentent des syndromes cliniques avec des phénotypes suffisamment caractéristiques pour être reconnus cliniquement. Actuellement la FISH est la technique de choix pour rechercher ces syndromes. Plusieurs syndromes microdélétionnels peuvent être confirmés aisément, les plus recherchés sont Le syndrome de Williams (microdélétion en 7q11.23) et le syndrome de la délétion 22q11 (microdélétion en 22q11.2). Le syndrome de Williams est caractérisé par une anomalie du développement qui associe un retard psycho-moteur, une dysmorphie du visage évocatrice et un profil cognitif et comportemental spécifique, une sténose aortique supravalvulaire -SASV- le plus souvent. Le Syndrome de la délétion 22q11 se caractérise par l’association de plusieurs malformations d’expression variable: une cardiopathie congénitale de type conotroncal, une dysmorphie faciale discrète mais caractéristique et une hypoplasie du thymus et des parathyroïdes. Nous rapportons nos premières observations au CHU Hassan II confirmées par FISH : Syndrome de la délétion 22q11 (n:2) et un syndrome de Williams. Le but de cet article est la mise à jour de nos connaissances sur ces deux syndromes et la mise en valeur du rôle de la cytogénétique moléculaire dans le diagnostic et le conseil génétique des syndromes microdélétionnels.

    2011-05-01

    The complete expression for the intensity in pseudo-scalar meson photoproduction with a polarized beam, target, and recoil baryon is derived using a density matrix approach that offers great economy of notation. A Cartesian basis with spins for all particles quantized along a single direction, the longitudinal beam direction, is used for consistency and clarity in interpretation. A single spin-quantization axis for all particles enables the amplitudes to be written in a manifestly covariant fashion with simple relations to those of the well-known CGLN formalism. Possible sign discrepancies between theoretical amplitude-level expressions and experimentally measurable intensity profiles are dealt with carefully. Our motivation is to provide a coherent framework for coupled-channel partial-wave analysis of several meson photoproduction reactions, incorporating recently published and forthcoming polarization data from Jefferson Lab.

    The purpose of this observational study was to assess Guillain-Barre´ syndrome (GBS) patients' satisfaction with physiotherapy in the acute and sub-acute setting, and provide an overview of inpatient case management, including the number of complications. Twenty-seven patients admitted to Sir Charles Gairdner Hospital (SCGH) with GBS between 1 May 2005 and 30 April 2010 were considered for inclusion. Nineteen patients consented and a waiver of consent was granted for four other patients. Data were collected from case-note audit (n = 23) and telephone survey (n = 19) during June and July 2011. Participants receiving physiotherapy (n = 16) reported they were satisfied with management (87%), treatment frequency (88%), duration (94%), and timetabling (81%) of treatment and the professionalism and rapport (100%) of physiotherapists. Median length of hospital stay was 20 days (range 5-198) for 23 participants. Physiotherapists documented patient assessment within 2 days from admission (range 1-5). First functional improvements were documented on day 6 (median, range 2-34). Physiotherapists were most commonly first to mobilize patients to sit, stand, transfer, and walk (83%, 82%, 81%, and 90%, respectively). Twenty patients (87%) developed complications during their hospital stay, the most common being low back pain (61%). This study has demonstrated that GBS patients were satisfied with care provided by physiotherapy.

    The memory profile of individuals with Down syndrome (DS) has mainly been examined through traditional laboratory tasks, often revealing substantial deficits in episodic and declarative memory. Little is known about the relation between memory abilities as measured in the laboratory versus naturalistic settings in this population, and no questionnaire assessments of everyday memory have been formally validated for this group. The current study's aims were twofold: 1) to describe the psychometric characteristics of a parent-reported everyday memory measure (the Observer Memory Questionnaire - Parent Form, OMQ-PF) in this population with known hippocampal and memory impairment (i.e., DS, ages 7-35 years), and 2) to determine if the measure has the sensitivity to detect impairments, thus providing some of the first data to document parent reports of everyday memory in individuals with DS. The results indicate that this scale is a reliable instrument for detecting and tracking memory deficits over time in this population. We found a correlation between parent reports of everyday memory difficulties and well-replicated deficits in a laboratory-based memory task (i.e., place-object paired associates learning). Our results suggest that the OMQ-PF has the potential to be used as a tool to help to track the status of memory function in this group both for use in descriptive studies and in studies of behavior and pharmacological intervention.

    Full Text Available Abstract Background Early detection and treatment of the metabolic syndrome may prevent diabetes and cardiovascular disease. Our aim was to assess remission of the metabolic syndrome and its determinants after a population based screening without predefined intervention in the Netherlands. Methods In 2006 we detected 406 metabolic syndrome cases (The National Cholesterol Education Program’s Adult Treatment Panel III (NCEP ATP III definition among apparently healthy individuals with an increased waist circumference. They received usual care in a primary care setting. After three years metabolic syndrome status was re-measured. We evaluated which baseline determinants were independently associated with remission. Results The remission rate among the 194 participants was 53%. Baseline determinants independently associated with a remission were the presence of more than three metabolic syndrome components (OR 0.46 and higher levels of waist circumference (OR 0.91, blood pressure (OR 0.98 and fasting glucose (OR 0.60. Conclusions In a population with screen-detected metabolic syndrome receiving usual care, more than half of the participants achieved a remission after three years. This positive result after a relatively simple strategy provides a solid basis for a nation-wide implementation. Not so much socio-demographic variables but a higher number and level of the metabolic syndrome components were predictors of a lower chance of remission. In such cases, primary care physicians should be extra alert.

This study aimed to determine effects of long-term GH treatment and puberty on BMD of total body (BMDTB), lumbar spine (BMDLS), and bone mineral apparent density of the lumbar spine (BMADLS) in children with PWS. This was a prospective longitudinal study of a Dutch PWS cohort. Seventy-seven children with PWS who remained prepubertal during GH treatment for 4 years and 64 children with PWS who received GH treatment for 9 years participated in the study. The children received GH treatment, 1 mg/m(2)/day (≅ 0.035 mg/kg/d). BMDTB, BMDLS, and BMADLS was measured by using the same dual-energy x-ray absorptiometry machine for all annual measurements. In the prepubertal group, BMDTB standard deviation score (SDS) and BMDLSSDS significantly increased during 4 years of GH treatment whereas BMADLSSDS remained stable. During adolescence, BMDTBSDS and BMADLSSDS decreased significantly, in girls from the age of 11 years and in boys from the ages of 14 and 16 years, respectively, but all BMD parameters remained within the normal range. Higher Tanner stages tended to be associated with lower BMDTBSDS (P = .083) and a significantly lower BMADLSSDS (P = .016). After 9 years of GH treatment, lean body mass SDS was the most powerful predictor of BMDTBSDS and BMDLSSDS in adolescents with PWS. This long-term GH study demonstrates that BMDTB, BMDLS, and BMADLS remain stable in prepubertal children with PWS but decreases during adolescence, parallel to incomplete pubertal development. Based on our findings, clinicians should start sex hormone therapy from the age of 11 years in girls and 14 years in boys unless there is a normal progression of puberty.

    Compounds in cocoa and chocolate have established cardiovascular benefits, including beneficial effects on insulin resistance, a risk factor for type 2 diabetes mellitus. The aims of this study was to investigate relations between habitual chocolate intakes and diabetes mellitus. Cross-sectional and prospective analyses were undertaken on 953 community-dwelling participants (mean age 62 years, 59% women) from the Maine-Syracuse Longitudinal Study (MSLS). Habitual chocolate intakes, measured using a food frequency questionnaire, were related to prevalence of diabetes mellitus (cross-sectionally) and with risk of diabetes measured approximately five years later (prospectively). We also examined the relation between diabetes (the predictor) and chocolate consumption (the outcome) up to 30 years later. Chocolate intake was inversely associated with type 2 diabetes. Compared to participants who consumed chocolate more than once per week, those who never or rarely ate chocolate exhibited a significantly higher odds of having type 2 diabetes 5 years later (OR: 1.91, 95% CI: 1.03, 3.55, p = 0.04), after adjustment for cardiovascular, lifestyle and dietary factors including other polyphenol-rich beverages. However, individuals diagnosed with diabetes prior to the nutritional assessment consumed lower amounts of chocolate at the time of the dietary assessment. Our findings suggest that relations between chocolate and type 2 diabetes may be bi-directional. Copyright © 2016 Elsevier Ltd. All rights reserved.

The developmental and clinical findings are discussed. When an association of diaphragmatic hernia with situs viscerum inversus is encountered, physicians should be mindful of the possibility of Kartagener syndrome because this condition could significantly affect the morbidity of the patient.

    One important cardiovascular morbidity that is associated with obesity hypoventilation syndrome (OHS) is the development of pulmonary hypertension (PH). However, few studies have assessed PH in OHS patients. Therefore, we prospectively assessed the prevalence of PH in a large sample of OHS patients. In this prospective observational study, all consecutive OHS patients referred to the sleep disorders clinic during the study period were included. All patients underwent overnight polysomnography (PSG), spirometry, arterial blood samples and thyroid tests. Transthoracic echocardiography was performed for patients who agreed to participate in the study. PH was defined as systolic pulmonary artery pressure (SPAP) >40 mmHg. Echocardiographic data were available for 77 patients with a mean age of 60.5±11.7 years, a BMI of 43.2±10.4 kg/m2, and an Epworth Sleepiness Scale (ESS) score of 11.4±5.5. SPAP was >40 mmHg in 53 patients (68.8%), with a mean SPAP of 64.1±17.1 mmHg. There were no differences between the OHS patients with PH and those with normal PAP in terms of age, BMI, presenting symptoms, comorbidities, arterial blood gasses (ABG), and spirometric and PSG parameters. Approximately 71.4% of women and 61.9% of men with OHS also had PH. SPAP was >40-55 mmHg in 19 (24.7%) patients (18 women), >55-70 mmHg in 15 (19.5%) patients (6 women) and >70 mmHg in 19 (24.7%) patients (16 women). Severe PH (SPAP >70 mmHg) was diagnosed in 28.6% of the women and 14.3% of the men. PH is very common among patients with OHS who have been referred to sleep disorders clinics. PH should be considered in the regular clinical assessment of all patients with OHS.

  10. Profiling sirolimus-induced inflammatory syndrome: a prospective tricentric observational study.

    Directory of Open Access Journals (Sweden)

    Fanny Buron

    Full Text Available BACKGROUND: The use of the immunosuppressant sirolimus in kidney transplantation has been made problematic by the frequent occurrence of various side effects, including paradoxical inflammatory manifestations, the pathophysiology of which has remained elusive. METHODS: 30 kidney transplant recipients that required a switch from calcineurin inhibitor to sirolimus-based immunosuppression, were prospectively followed for 3 months. Inflammatory symptoms were quantified by the patients using visual analogue scales and serum samples were collected before, 15, 30, and 90 days after the switch. RESULTS: 66% of patients reported at least 1 inflammatory symptom, cutaneo-mucosal manifestations being the most frequent. Inflammatory symptoms were characterized by their lability and stochastic nature, each patient exhibiting a unique clinical presentation. The biochemical profile was more uniform with a drop of hemoglobin and a concomitant rise of inflammatory acute phase proteins, which peaked in the serum 1 month after the switch. Analyzing the impact of sirolimus introduction on cytokine microenvironment, we observed an increase of IL6 and TNFα without compensation of the negative feedback loops dependent on IL10 and soluble TNF receptors. IL6 and TNFα changes correlated with the intensity of biochemical and clinical inflammatory manifestations in a linear regression model. CONCLUSIONS: Sirolimus triggers a destabilization of the inflammatory cytokine balance in transplanted patients that promotes a paradoxical inflammatory response with mild stochastic clinical symptoms in the weeks following drug introduction. This pathophysiologic mechanism unifies the various individual inflammatory side effects recurrently reported with sirolimus suggesting that they should be considered as a single syndromic entity.

    In modern medicine the diagnosis and prognosis of an abnormal metabolic condition is based on blood borne measurements involving one or more biomarker. This paper reports the development of a minimal negative feedback model for the description of longitudinal biomarkers concentrations for treatment of osteoporosis in postmenopausal women. Literature data were obtained from double-blind, placebo-controlled clinical trial over three years. There were four treatment groups: 1) Placebo, 2) Alendronate, 3) Conjugated Estrogen, and/or 4) Combination therapy. The negative feedback model consists of a biomarker and a companion controller. By considering the above basal biomarker values it is shown that the dynamics can be described by a second order differential equation without the involvement of biomarker production rate. The second order differential equation is also analogous to classical negative feedback servomechanism model with two parameters ω(n) and ξ. It was assumed that the rate constants defining the negative feedback model were equal which would set ξ to 0.707 with only ω(n) to be estimated. ω(n) was estimated for both lumbar spine bone mineral density (BMD) and bone-specific alkaline phosphatase (BAP) in four treatments groups. The t(½) of BMD and BAP were estimated at 26.8 (0.30) and 9.4 (0.30) days respectively. The negative feedback model of BMD supports the mechanism whereby Conjugated Estrogen and Alendronate decrease the clearance rate constant of BMD analogous to increased apoptosis of osteoclasts. The linked negative feedback models facilitate a mechanism based prediction of BMD using the concentrations of the bone turnover marker BAP.

    Full Text Available BACKGROUND: Palliative care is increasingly offered earlier in the cancer trajectory but rarely in Idiopathic Parkinson's Disease(IPD, Progressive Supranuclear Palsy(PSP or Multiple System Atrophy(MSA. There is little longitudinal data of people with late stage disease to understand levels of need. We aimed to determine how symptoms and quality of life of these patients change over time; and what demographic and clinical factors predicted changes. METHODS: We recruited 82 patients into a longitudinal study, consenting patients with a diagnosis of IPD, MSA or PSP, stages 3-5 Hoehn and Yahr(H&Y. At baseline and then on up to 3 occasions over one year, we collected self-reported demographic, clinical, symptom, palliative and quality of life data, using Parkinson's specific and generic validated scales, including the Palliative care Outcome Scale (POS. We tested for predictors using multivariable analysis, adjusting for confounders. FINDINGS: Over two thirds of patients had severe disability, over one third being wheelchair-bound/bedridden. Symptoms were highly prevalent in all conditions - mean (SD of 10.6(4.0 symptoms. More than 50% of the MSA and PSP patients died over the year. Over the year, half of the patients showed either an upward (worsening, 24/60 or fluctuant (8/60 trajectory for POS and symptoms. The strongest predictors of higher levels of symptoms at the end of follow-up were initial scores on POS (AOR 1.30; 95%CI:1.05-1.60 and being male (AOR 5.18; 95% CI 1.17 to 22.92, both were more predictive than initial H&Y scores. INTERPRETATION: The findings point to profound and complex mix of non-motor and motor symptoms in patients with late stage IPD, MSA and PSP. Symptoms are not resolved and half of the patients deteriorate. Palliative problems are predictive of future symptoms, suggesting that an early palliative assessment might help screen for those in need of earlier intervention.

    Few studies have investigated developmental strengths and weaknesses within the cognitive profile of children and adolescents with fragile X syndrome (FXS), a single-gene cause of inherited intellectual impairment. With a prospective longitudinal design and using normalized raw scores (Z scores) to circumvent floor effects, we measured cognitive functioning of 184 children and adolescents with FXS (ages 6 to 16) using the Wechsler Scale of Intelligence for Children on one to three occasions for each participant. Participants with FXS received lower raw scores relative to the Wechsler Scale of Intelligence for Children normative sample across the developmental period. Verbal comprehension, perceptual organization, and processing speed Z scores were marked by a widening gap from the normative sample, while freedom from distractibility Z scores showed a narrowing gap. Key findings include a relative strength for verbal skills in comparison with visuospatial-constructive skills arising in adolescence and a discrepancy between working memory (weakness) and processing speed (strength) in childhood that diminishes in adolescence. Results suggest that the cognitive profile associated with FXS develops dynamically from childhood to adolescence. Findings are discussed within the context of aberrant brain morphology in childhood and maturation in adolescence. We argue that assessing disorder-specific cognitive developmental profiles will benefit future disorder-specific treatment research.

    The aims of the present study were to delineate the characteristic patterns of 3-dimensional (3D) mandibular movement in patients with skeletal Class III malocclusion compared with normal individuals and to investigate the longitudinal changes in mandible and condylar motion after orthognathic surgery (OGS). The subjects in the present prospective study consisted of 2 groups. The OGS group included 24 patients with skeletal Class III who underwent OGS. The control group consisted of 25 patients who underwent orthodontic treatment only. The patient records included demographic data, lateral and posteroanterior cephalometric radiographs before treatment, and serial mandibular motion data. In the OGS group, the mandibular motion data were obtained before OGS (T1), 1 month after OGS (T2), and at least 6 months after OGS (T3). The differences in cephalometric measurements and mandibular movements between the 2 groups were compared. The Pearson correlation test was performed to assess the relationship between the cephalometric measurements and the mandibular movements. Serial changes in mandibular movement in the OGS group were also compared. The skeletal pattern in the OGS group demonstrated retrusive maxilla and a protrusive mandible, with a larger mandibular plane angle. For the incisal range of motion, the OGS group's maximal mouth opening was larger than the control group's by 6.9 mm. In the OGS group, the condylar range of motion in retrusion and the Bennett angle were asymmetric. Skeletal Class III patients tended to have a smaller range of condylar retrusion. At 1 month after OGS, the maximal incisal range of motion decreased from 57.23 to 25.61 mm. Other variables, including laterotrusion, movement velocity, and angle and distance of condylar movement in protrusion, reduced significantly. The Bennett angle demonstrated increased symmetry on both sides. Six months after OGS, the condylar motion in opening demonstrated improvements, but to a lesser extent than at

    The aim of this study is to summarize the design and methodology of a prospective, longitudinal, observational cohort study to investigate how glaucoma affects patients' quality of life and visually-related function over a 4-year period. One hundred sixty-one (161) subjects were enrolled in this ongoing study. Patients between the ages of 21-85 years with a minimum 2-year diagnosis of primary open-angle glaucoma, chronic primary angle-closure glaucoma or pseudoexfoliation glaucoma were included. Each patient visited Wills Eye Hospital for a baseline visit. Follow-up is planned for a minimum of 4 years, with annual visits. Each visit includes (1) Clinical evaluation: a slit lamp examination, fundoscopy, intraocular pressure measurement, visual field examination, spectral domain optical coherence tomography, Pelli-Robson Contrast Sensitivity test and the Spaeth-Richman Contrast Sensitivity test; (2) a performance based measure: the Compressed Assessment of Ability Related to Vision; and (3) Subjective measures of vision-related quality of life (the National Eye Institute Visual Functioning Questionnaire 25 and the Modified Glaucoma Symptom Scale). The results of this ongoing, prospective, longitudinal study are expected to shed light on the relationships between clinical measures, performance-based measures and subjective measures of well-being, in order to assess changes in the quality of life and the ability to function of patients with glaucoma over time.

  16. Longitudinal excursion and strain in the median nerve during novel nerve gliding exercises for carpal tunnel syndrome.

    Nerve and tendon gliding exercises are advocated in the conservative and postoperative management of carpal tunnel syndrome (CTS). However, traditionally advocated exercises elongate the nerve bedding substantially, which may induce a potentially deleterious strain in the median nerve with the risk of symptom exacerbation in some patients and reduced benefits from nerve gliding. This study aimed to evaluate various nerve gliding exercises, including novel techniques that aim to slide the nerve through the carpal tunnel while minimizing strain ("sliding techniques"). With these sliding techniques, it is assumed that an increase in nerve strain due to nerve bed elongation at one joint (e.g., wrist extension) is simultaneously counterbalanced by a decrease in nerve bed length at an adjacent joint (e.g., elbow flexion). Excursion and strain in the median nerve at the wrist were measured with a digital calliper and miniature strain gauge in six human cadavers during six mobilization techniques. The sliding technique resulted in an excursion of 12.4 mm, which was 30% larger than any other technique (psliding technique. Nerve gliding associated with wrist movements can be considerably increased and nerve strain substantially reduced by simultaneously moving neighboring joints. These novel nerve sliding techniques are biologically plausible exercises for CTS that deserve further clinical evaluation. Copyright (c) 2007 Orthopaedic Research Society.

    Given that Alzheimer's pathology develops silently over decades in Down syndrome (DS), prognostic biomarkers of dementia are a major need. We investigated the plasma levels of Aβ, proNGF, tPA, neuroserpin, metallo-proteases and inflammatory molecules in 31 individuals with DS (with and without dementia) and in 31 healthy controls. We examined associations between biomarkers and cognitive decline. Aβ40 and Aβ42 were elevated in DS plasma compared to controls, even in DS individuals without dementia. Plasma Aβ correlated with the rate of cognitive decline across 2 years. ProNGF, MMP-1, MMP-3, MMP-9 activity, TNF-α, IL-6, and IL-10 were higher in DS plasma, even at AD-asymptomatic stages. Declining plasma Aβ42 and increasing proNGF levels correlated with cognitive decline. A combined measure of Aβ and inflammatory molecules was a strong predictor of prospective cognitive deterioration. Our findings support the combination of plasma and cognitive assessments for the identification of DS individuals at risk of dementia. Copyright © 2016 The Alzheimer's Association.

    The association between frailty and malnutrition is widely noted, but the common and distinct aspects of this relationship are not well understood. We investigated the prevalence of prefrailty/frailty and malnutrition/nutritional risk; their overlapping prevalence; compared their sociodemographic, physical, and mental health risk factors; and assessed their association, independently of other risk factors. Cross-sectional study of population-based cohort (Singapore Longitudinal Ageing Study [SLAS]-1 [enrolled 2003-2005] and SLAS-2 [enrolled 2010-2013]) of community-dwelling older Singaporeans aged ≥55 (n = 6045). Mini Nutritional Assessment (MNA)-Short Form (SF), Nutritional Screening Initiative (NSI) Determine Checklist, Fried physical frailty phenotype. The overall prevalence of MNA malnutrition was 2.8%, and at risk of malnutrition was 27.6%; the prevalence of frailty and prefrailty were 4.5%, and 46.0% respectively. Only 26.5% of participants who were malnourished were frail, but 64.2% were prefrail (totally 90.7% prefrail or frail). The prevalence of malnutrition among frail participants was 16.1%, higher than in other studies (10%); nearly one-third of the whole population sample had normal nutrition while being prefrail (27.7%) or frail (1.5%). The prevalence of risk factors for prefrailty/frailty and malnutrition/nutritional risk were remarkably similar. MNA at risk of malnutrition and malnutrition were highly significantly associated with prefrailty (odds ratio [OR] 2.11 and 6.71) and frailty (OR 2.72 and 17.4), after adjusting for many other risk factors. The OR estimates were substantially lower with NSI moderate and high nutritional risk for prefrailty (OR 1.39 and 1.74) and frailty (OR 1.27 and 1.93), but remain significantly elevated. Frailty and malnutrition are related but distinct conditions in community-dwelling older adults. The contribution of poor nutrition to frailty in this population is notably greater. Both frail/prefrail elderly and

    To investigate whether serial anticardiolipin determination contributes to the clinical management of patients with systemic lupus erythematosus (SLE) with no previous sign of the antiphospholipid syndrome (APS). In 90 patients with SLE with no previous clinical manifestations of the APS, repeated clinical evaluations were performed, and serial blood samples (obtained over a 30 month period, range 13-53 mo) were screened for antiphospholipid antibodies (aPL). Anticardiolipin antibodies (aCL) were detected using an ELISA and considered positive if the result was >25 GPL on 2 separate occasions. Patients were not required to be on a specific treatment regimen during the study. Thirty-four patients (37%) had at least one positive ELISA and 11 (11/90, 12%) 2 positive ELISA for IgG aCL during the study. Lupus anticoagulant (LAC) was found in 16 patients, and a false positive VDRL in 5. At study completion, the total number of clinical or laboratory events associated with APS was 30. In univariate analysis, aCL was significantly associated only with LAC (paCL also correlated with hemoglobin level, anti-DNA antibody, leukocyte count, and the SLE Disease Activity Index (SLEDAI). LAC and aCL were significantly associated with each other (OR 5.17; 95% CI 1.5-17.7), but LAC had a better positive predictive value than aCL for arterial thrombosis and neurological events. Among our patients with SLE without previous clinical manifestations of APS, positive aCL did not predict the occurrence of APS within the next 3 years, but was statistically related to the clinical disease activity (SLEDAI).

    The current study examined the contribution of marital satisfaction to symptoms of depression among patients with acute coronary syndrome (ACS) and their partners. The sample comprised of 91 ACS male patients and their female partners. Data were collected at the time of initial hospitalization and 6 months later. Patients' and partners' assessments of marital satisfaction were measured using the ENRICH scale. Symptoms of depression were measured using the Brief Symptoms Inventory (BSI). Dyadic analysis applying the Actor-Partner Inter-dependence Model (APIM) was used. Different patterns emerged for the two phases. In the acute phase, only the Actor effect was significant: for both patients and partners, one's greater marital satisfaction was associated with one's lower levels of depression. In the chronic phase, both Actor and Partner effects were significant, while different trends were found for patients and partners. Partners' marital satisfaction was associated with their own and the patients' decreased depression symptoms, whereas among patients, higher levels of marital satisfaction were associated with elevated levels of depression both for themselves and for their partners. A dyadic perspective and phases of illness have to be taken into account in understanding adjustment and developing interventions following ACS. What is already known on this subject?

    Psychiatric disorders such as psychosis are highly prevalent in adults with Prader-Willi syndrome (PWS). However, knowledge about the presence and progression of psychiatric disorders in children with PWS is very limited. Sixty-one children with PWS aged 7-17 years were tested using the Diagnostic Interview Schedule for Children (DISC) and Compulsive Behaviour Checklist (CBC), and 38/61 were retested after 2 years. Prevalence of psychiatric disorders and the association with age, gender, genetic subtype, and total IQ were assessed. In addition, occurrence and characteristics of compulsions were determined. Prior to the study, two boys were known with psychotic symptoms and treated with antipsychotics. At baseline, none scored positive for psychotic disorder. During the follow-up, only one boy with known psychotic symptoms required a dose adjustment of his antipsychotic medication. After 2 years, none of the children had a psychotic disorder according to the DISC. Oppositional defiant disorder (ODD) was the most common diagnosis and present in 20% of children with PWS, and this was not associated with age (β = -0.081, P = 0.546), gender (β = 0.013, P = 0.923), genetic subtype (β = -0.073, P = 0.584), or total IQ (β = -0.150, P = 0.267). The most common compulsions were hoarding and fixed hygiene sequences. In our large group of 61 children with PWS, the majority had no psychotic disorder and no progression was found during 2-year follow-up. ODD was present in 20% of children. No changes in the prevalence of psychiatric disorders were found during the 2-year follow-up study and genetic subtype was not related to psychosis, depression, or ODD. © 2015 Wiley Periodicals, Inc.

    Objective: Our aim was to evaluate the serial evolution of regenerative nodules in patients with Budd-Chiari syndrome (BCS) treated with portal-systemic shunts, using multiphasic multidetector computed tomography (MDCT). Materials and methods: Five patients each underwent three MDCT exams over an extended period ranging from 36 to 42 months. Two radiologists in consensus retrospectively reviewed each exam for each patient. Individual nodules were grouped according to size (size I: nodules with diameter {<=}15 mm; size II: >15 mm but <30 mm; size III: {>=}30 mm), pattern of enhancement (A: homogeneously hypervascular or B: with central scar), and segmental location. Four nodules classified as size II, which increased in size over time, were needle-biopsied. Results: We detected 61 nodules at the first exam, 66 nodules at the second exam (7 nodules disappeared and 12 new nodules), and 85 nodules at the third exam (8 disappeared and 27 new) for a total of 212 findings. Nodules were mostly found in the right hepatic lobe. Fourteen of the 15 nodules that disappeared over time were size I and enhancement pattern A. At unenhanced MDCT, 204 (96%) of the 212 findings were isodense. Overall, 100 nodules, including the 61 initially detected, were considered newly diagnosed; of these 84 (84%) were size I and pattern A. Of 57 nodules considered size I and pattern A at the first or second exam, 24 (42%) changed to pattern B at the third exam and either size II (n = 18) or III (n = 6). The four biopsied nodules were each confirmed as benign regenerative nodule. No patient developed HCC at 5-year follow-up period. Conclusion: Hepatic nodules in BCS patients not only increase in number over time but may also increase in size and develop a central scar.

    After low anterior resection for rectal cancer, creation of a diverting stoma is recommended. Data on the impact of a diverting stoma on quality of life are conflicting. Optimal timing of stoma closure in the setting of adjuvant chemotherapy is unclear. The purpose of this study was to investigate the impact of a diverting stoma on quality of life in patients undergoing rectal cancer resection before and after stoma closure. Furthermore, the study was conducted to look at the timing of stoma reversal and the potential influence of factors such as adjuvant chemotherapy. This was a longitudinal, observational, multicenter study. The study was conducted at 17 German colorectal centers. Patients with rectal cancer who planned for elective curative surgery with creation of temporary diverting stoma were included. This longitudinal observational study assessed quality of life at 3 occasions using European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire-Core Questionnaire/Colorectal Cancer Module before cancer resection, before stoma closure, and 6 months after stoma closure. Furthermore, the timing of stoma closure and continence were evaluated. A total of 120 patients (64% men; mean age, 63.2 ± 11.5 years) were analyzed. Longitudinal global quality of life was not influenced by the presence of a stoma. Several functional and GI symptom scales were markedly impaired after stoma creation. Physical, role functioning, and sexual interest recovered after stoma closure. Social functioning stayed impaired (p stoma closure was 5 months (range, 17 days to 18 months). A total of 3.4% of patients had very early stoma closure (within 30 days). Adjuvant chemotherapy delayed stoma closure (median, 5.6 vs 3.4 months without chemotherapy; p = 0.0001). The study was limited by its missing quality-of-life data for sexual function. The presence of a stoma had a negative impact on social functioning and GI symptoms. However, this had no clinically relevant

    Essential fatty acid status as well as docosahexaenoic acid (DHA, 22:6n-3) declines during pregnancy and lactation. As a result, the DHA status may not be optimal for child development and may increase the risk for maternal postpartum depression. The objective of this study was to assess changes in the maternal fatty acid status from pregnancy to 12 months postpartum, and to study the impact of seafood consumption on the individual fatty acid status. Blood samples and seafood consumption habits (gestation week 28, and three-, six- and 12 months postpartum) were collected in a longitudinal observational study of pregnant and postpartum women (n = 118). Multilevel linear modeling was used to assess both changes over time in the fatty acid status of red blood cells (RBC), and in the seafood consumption. Six fatty acids varied the most (>80%) across the four time points analyzed, including the derivative of the essential α-linoleic acid (ALA, 18:3n-3), DHA; the essential linoleic acid (LA, 18:2 n-6); and the LA derivative, arachidonic acid (AA, 20:4n-6). Over all, a large variation in individuals' DHA- and AA status was observed; however, over the 15-month study period only small inter-individual differences in the longitudinal trajectory of DHA- and AA abundance in the RBC were detected. The median intake of seafood was lower than recommended. Regardless, the total weekly frequency of seafood and eicosapentaenoic acid (EPA, 20:5n-3)/DHA-supplement intake predicted the maternal level of DHA (μg/g RBC). The period of depletion of the maternal DHA status during pregnancy and lactation, seem to turn to repletion from about six months postpartum towards one year after childbirth, irrespective of RBC concentration of DHA during pregnancy. Seafood and EPA/DHA-supplement intake predicted the DHA levels over time. www.helseforskning.etikkom.no 2009/570/REC, project number: 083.09.

    Background The primary objective of the current study was to examine the childhood predictors of adolescent reading comprehension in velo-cardio-facial syndrome (VCFS). Although much research has focused on mathematics skills among individuals with VCFS, no studies have examined predictors of reading comprehension. Methods 69 late adolescents with VCFS , 23 siblings of youth with VCFS and 30 community controls participated in a longitudinal research project and had repeat neuropsychological test batteries and psychiatric evaluations every 3 years. The Wechsler Individual Achievement Test – 2nd edition (WIAT-II) Reading Comprehension subtest served as our primary outcome variable. Results Consistent with previous research, children and adolescents with VCFS had mean reading comprehension scores on the WIAT-II which were approximately two standard deviations below the mean and word reading scores approximately one standard deviation below the mean. A more novel finding is that relative to both control groups, individuals with VCFS demonstrated a longitudinal decline in reading comprehension abilities yet a slight increase in word reading abilities. In the combined control sample, WISC-III FSIQ, WIAT-II Word Reading, WISC-III Vocabulary and CVLT-C List A Trial 1 accounted for 75% of the variance in Time 3 WIAT-II Reading Comprehension scores. In the VCFS sample, WISC-III FSIQ, BASC-Teacher Aggression, CVLT-C Intrusions, Tower of London, Visual Span Backwards, WCST non-perseverative errors, WIAT-II Word Reading and WISC-III Freedom from Distractibility index accounted for 85% of the variance in Time 3 WIAT-II Reading Comprehension scores. A principal component analysis with promax rotation computed on the statistically significant Time 1 predictor variables in the VCFS sample resulted in three factors: Word reading decoding / Interference control, Self-Control / Self-Monitoring and Working Memory.

    To obtain consensus on the minimum data items for an observational cohort study in RA in the UK and to make available the process for similar studies and other rheumatic conditions. Individuals with a diverse range of expertise and backgrounds were invited to participate in a process of proposing a minimum core dataset (MCD) for research studies, commissioned by Arthritis Research UK as part of the larger INBANK project. The group included patients and representatives from clinical and academic rheumatology, outcomes science, stratified medicine, health economics, and national professional and academic bodies/committees. A process was devised based on OMERACT principles for reviewing aims/objectives, defining the scope, identifying the important research questions and selecting key domains. Following the initial multistakeholder meeting, subsequent teleconferences and email communications: consensus was obtained on the most important and relevant research questions; agreement on how the OMERACT Core Areas (life impact, pathophysiological manifestations, resource use and death) could form the basis of a MCD; and consensus on 22 items for inclusion into a MCD. Workshops were undertaken for two essential items that required further exploration: work/social participation and co-morbidity. Reaching a consensus for the proposed minimal data items for long-term observational cohort studies of RA in the UK posed novel challenges and opportunities, and was largely successful. Further work is needed for selecting instruments for two important items and for achieving compatibility with other UK national initiatives, and more widely across Europe.

    Maternal mind-mindedness, or the tendency to view the child as a mental agent, has been shown to predict sensitive and responsive parenting behavior. As yet the role of mind-mindedness has not been explored in the context of feeding interactions. This study evaluates the relations between maternal mind-mindedness at 6 months of infant age and subsequently observed maternal sensitivity and feeding behaviors with children at age 1 year. Maternal mind-mindedness was greater in mothers who had breast-fed compared to formula-fed. Controlling for breast-feeding, mind-mindedness at 6 months was correlated with observations of more sensitive and positive feeding behaviors at 1 year of age. Mind-mindedness was also associated with greater general maternal sensitivity in play and this general parenting sensitivity mediated the effect of mind-mindedness on more sensitive and positive feeding behaviors. Interventions to promote maternal tendency to consider their child's mental states may encourage more adaptive parental feeding behaviors.

    Full Text Available Over 133,000 children present to hospitals with Acute Encephalitis Syndrome (AES annually in Asia. Japanese encephalitis (JE accounts for approximately one-quarter of cases; in most cases no pathogen is identified and management is supportive. Although JE is known to result in neurological impairment, few studies have examined the wider impact of JE and AES on patients and their families.Children (aged 1 month-14 years with AES were assessed 5-12 months after discharge from two Nepali hospitals. Assessment included clinical examination, the Liverpool Outcome Score (LOS - a validated assessment of function following encephalitis, questionnaires about the child's social participation since discharge, and out-of-pocket costs to the family. Children were classified as JE or 'other AES' based on anti-JE virus antibody titres during acute illness. Contact was made with the families of 76% (73/96 of AES children. Six children had died and one declined participation. 48% (32/66 reported functional impairment at follow-up, most frequently affecting behaviour, language or limb use. Impairment was more frequent in JE compared to 'other AES' cases (68% [13/19] versus 40% [19/47]; p = 0.06. 49% (26/53 had improvement in LOS between discharge and follow-up. The median out-of-pocket cost to families, including medical bills, medication and lost earnings was US$ 1151 (10 times their median monthly income for children with severe/moderate impairment and $524 (4.6 times their income for those with mild/no impairment (P = 0.007. Acute admission accounted for 74% of costs. Social participation was limited in 21% of children (n = 14.Prolonged functional impairment was common following AES. Economic impact to families was substantial. Encouragingly, almost half the children improved after discharge and most reported sustained social participation. This study highlights a need for long-term medical support following AES. Rationalisation of initial expensive hospital

    We describe a case of asymptomatic polysplenic syndrome as suggested by ultrasonography, gastrointestinal series, computed tomography, magnetic resonance imaging scans and arteriography, and confirmed at surgery. Spleen malformation is frequently associated with heterotaxia and other malformations of the thoracic and abdominal organs, but no pathognomonic features can be detected in relation to this condition. In our patient, imaging studies revealed the presence of a polylobulated spleen in an atypical position below the liver, associated with malpositioning of the gastric fundus and gastro-oesophageal junction with interruption of the inferior vena cava, but no congenital heart disease. In conclusion, polysplenic syndrome is a rare clinical condition, occasionally found in asymptomatic adults. Radiological detection could be mistaken for mediastinal or abdominal pathological masses, and only a thorough study performed with several different radiological methods can determine the precise anatomy of the structures involved so as to be able to plan surgery where necessary.

    Full Text Available Childhood periodic syndromes are a group of functional states occurring at an early age, including in the first year of life, which are pre sently considered as equivalents or precursors for further migraine. Insufficient coverage of the problem in the Russian literature, the paroxysmal occurrence and periodic recurrence of these states are a frequent cause of readmissions, numerous, sometimes invasive studies, misdiagnoses, and, as a consequence, the use of aggressive, pathogenetically unsound therapy, which ultimately affects quality of life in a child. The review article highlights the basic issues of the epidemiology, etiology, pathogenesis, clinical manifestations of major forms of childhood periodic syndromes, as well as approaches to their diagnosis, treatment, and prediction. To familiarize a wide range of specialists, not only neurologists, with these conditions in children will, of course, reduce the overdiagnosis of various more serious diseases.

    Sleep disturbances are common in women, especially during pregnancy. Previous studies have confirmed the importance of sleep disturbances as a risk factor of adverse pregnancy outcomes and the need for screening and treatment of inadequate sleep. These reports, however, did not examine health-related quality of life which may be affected by sleep long before adverse clinical consequences are detectable in women during pregnancy. To examine the cross-sectional and longitudinal association between sleep and health-related quality of life in pregnant women. A prospective observational study. A university-affiliated hospital in Taiwan and participants' homes. A total of 164 pregnant women completed questionnaires and wore a wrist actigraphy monitor for 7 days each trimester. Objective sleep was measured by actigraphy, subjective sleep was measured by the Pittsburgh Sleep Quality Index, and health-related quality of life was measured using the SF-12v2 questionnaire across three trimesters. Multiple linear regression analyses were performed to evaluate the cross-sectional and longitudinal associations between sleep and health-related quality of life. Sixty-four (39.0%) women consistently had an average sleep efficiencyQuality Index global score>5 in all three trimesters. Cross-sectionally, more actigraphic daytime sleep (p=0.04) and better subjective sleep quality (pquality of life in first-trimester pregnant women. Better actigraphic sleep efficiency (p=0.04) and better subjective sleep quality (pquality of life in second-trimester pregnant women. Longer actigraphic total nighttime sleep (pquality (pquality of life in third-trimester pregnant women. Longitudinally, first-trimester actigraphic total nighttime sleep (pquality (pquality of life in the second and third trimester. Sleep disturbances are a highly prevalent and persistent problem in pregnant women. Adequate sleep is essential for women at all pregnancy stages and improving nocturnal sleep quantity and quality

    The aim of this longitudinal study was to evaluate the risk of surgery for subacromial impingement syndrome (SIS) in relation to neck-shoulder complaints and occupational biomechanical shoulder exposures. The study was based on the Musculoskeletal Research Database at the Danish Ramazzini Centre. We linked baseline questionnaire information from 1993-2004 on neck-shoulder complaints, job titles, psychosocial work factors, body mass index, and smoking with register information on first-time surgery for SIS from 1996-2008. Biomechanical exposure measures were obtained from a job exposure matrix based on expert judgment. We applied multivariable Cox regression. During 280 125 person-years of follow-up among 37 402 persons, 557 first-time operations for SIS occurred. Crude surgery rates increased from 1.1 to 2.5 per 1000 person-years with increasing shoulder load. Using no neck-shoulder complaints and low shoulder load at baseline as a reference, no neck-shoulder complaints and high shoulder load showed an adjusted hazard ratio (HR(adj)) of 2.55 [95% confidence interval (95% CI) 1.59-4.09], while neck-shoulder complaints in combination with high shoulder load showed an HR(adj) of 4.52 (95% CI 2.87-7.13). Subanalyses based on 18 856 persons showed an HR(adj) of 5.40 (95% CI 2.88-10.11) for complaints located specifically in the shoulder in combination with high shoulder load. Based on these findings, persons with neck-shoulder and especially shoulder complaints in combination with high shoulder load seem an obvious target group for interventions aimed at reducing exposures to prevent surgery for SIS.

    Polycystic ovary syndrome (PCOS) is a common condition in reproductive-aged women and a major female-specific risk factor of obesity, impaired glucose tolerance, and diabetes. We examined whether the genetic variation predisposing to PCOS affected glycemic changes in women with prior gestational diabetes mellitus (GDM) and whether such an effect was modified by changes in body adiposity, especially during and after pregnancy. This is a longitudinal study in Tianjin, China. We genotyped 7 genome-wide association study-identified PCOS single nucleotide polymorphisms and assessed gestational weight gain and changes in glycemic traits and weight at 1 to 5 years postpartum in 1133 women with prior GDM. The main outcome measure was postpartum glycemic changes. The PCOS genetic risk score significantly interacted with postpartum weight reduction on changes in fasting glucose and 2-h glucose (P for interaction = .032 and .007; respectively) after multivariable adjustment. In women with postpartum weight reduction of ≥ 5 kg/y, the genetic risk score was associated with decreased fasting and 2-h glucose, whereas an opposite genetic effect was found in women who lost less weight. The association between postpartum weight reduction and glycemic improvement was more significant among women with a higher genetic risk score. In a large cohort of Chinese women with a history of GDM, our data for the first time indicate that the genetic predisposition to PCOS may interact with postpartum weight reduction on long-term glycemic changes, emphasizing the importance of postpartum weight management in prevention of diabetes in this subgroup of women.

    Longitudinal data of children with Prader-Willi syndrome (PWS) treated with genotropin were registered in the Pfizer International Growth Database (KIGS). To evaluate efficacy and safety of growth hormone (GH) treatment in a large group of children with PWS. Data registered in KIGS from 1987 to 2012. Worldwide retrospective cohort study. Patients included 522 prepubertal children treated with GH for three years and 173 children who had reached adult height. Safety analysis included 2332 children. Intervention involved GH treatment. Height standard deviation score (SDS), body mass index (BMI) SDS, occurrence of serious adverse events, and deaths reported in KIGS. In prepubertal children, mean (standard deviation) height SDS improved to -0.31 (1.34) (P < 0.05) during three years of GH treatment. In the adolescent group, height SDS improved until the start of puberty to -0.22 (1.31) (P < 0.05) but had a loss of -0.77 (0.81) during puberty, resulting in a mean adult height SDS of -1.19 (1.37). Total height gain was 0.95 (1.32) SDS. BMI SDS increased in the prepubertal group from 1.11 (2.09) to 1.53 (1.43) (P < 0.05) and did not significantly change in the adolescent group, who had a BMI SDS at an adult height of 1.78 (1.26). KIGS contained 12 death reports. GH treatment in children with PWS significantly improves linear growth. BMI remains on average below +2 SDS, in contrast to the natural course of increasing obesity in PWS. Safety should be closely monitored in children with PWS, with and without GH treatment.

    Delayed return to work is common after acute respiratory distress syndrome (ARDS), but has undergone little detailed evaluation. We examined factors associated with the timing of return to work after ARDS, along with lost earnings and shifts in healthcare coverage. Five-year, multisite prospective, longitudinal cohort study of 138 2-year ARDS survivors hospitalised between 2004 and 2007. Employment and healthcare coverage were collected via structured interview. Predictors of time to return to work were evaluated using Fine and Grey regression analysis. Lost earnings were estimated using Bureau of Labor Statistics data. Sixty-seven (49%) of the 138 2-year survivors were employed prior to ARDS. Among 64 5-year survivors, 20 (31%) never returned to work across 5-year follow-up. Predictors of delayed return to work (HR (95% CI)) included baseline Charlson Comorbidity Index (0.77 (0.59 to 0.99) per point; p=0.04), mechanical ventilation duration (0.67 (0.55 to 0.82) per day up to 5 days; plost earnings, with average (SD) losses ranging from US$38 354 (21,533) to US$43 510 (25,753) per person per year. Jobless, non-retired survivors experienced a 33% decrease in private health insurance and concomitant 37% rise in government-funded coverage. Across 5-year follow-up, nearly one-third of previously employed ARDS survivors never returned to work. Delayed return to work was associated with patient-related and intensive care unit/hospital-related factors, substantial lost earnings and a marked rise in government-funded healthcare coverage. These important consequences emphasise the need to design and evaluate vocation-based interventions to assist ARDS survivors return to work. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    Multiple sclerosis (MS) has a variable progression with an early onset of atrophy. Individual longitudinal radiological evaluations (over decades) are difficult to perform due to the limited availability of magnetic resonance imaging (MRI) in the past, patients lost in follow-up, and the continuous updating of scanners. We studied a cohort with widespread disease duration at baseline. The observed individual atrophy rates over time of 10 years represented four decades of disease span. Thirty-seven MS patients (age range 24-65 years with disease duration 1-33 years) were consecutively selected and evaluated with MRI at baseline 1995 and in 1996. They were followed up for a decade (mean of 9.25 years, range 7.3-10 years) up to 2003-2005. Brain parenchymal volume and volumes of the supratentorial ventricles were analyzed with semi-automated volumetric measurements at three time points (1995, 1996, and 2003-2005). Volumetric differences were found over shorter periods of time (1-7 months); however, differences vanished by the end of follow-up. A uniform longitudinal decrease in brain volume and increase in ventricle volumes were found. Frontal horn width (1D) correlated strongest to 3D measures. No statistical differences of atrophy rates between MS courses were found. Supratentorial ventricular volumes were associated with disability and this association persisted during follow-up. Despite variable clinical courses, the degenerative effects of MS progression expressed in brain atrophy seem to uniformly progress over longer periods of time. These volumetric changes can be detected using 1D and 2D measurements performed on a routine PACS workstation. (orig.)

    To compare the differences of curative effects of herpes zoster treated with acupuncture based on syndrome differentiation combined with pricking and cupping and simple pricking and cupping. Eighty-six cases were randomly divided into an observation group (43 cases) and a control group (43 cases). In observation group, acupoints selection based on syndrome differentiation i.e. Quchi (LI 11), Zusanli (ST 36), Sanyinjiao (SP 6), etc. were selected and pricking and cupping at affected parts were applied, and the cases were classified into damp heat in liver and gallbladder, damp retention and spleen deficiency, and qi deficiency and blood stasis. In control group, all the cases were simplely treated with pricking and cupping at affected parts. The treatment was given once a day, and seven days were made one session. The curative effect was evaluated after 2 courses, and the follow-up was carried on after 1 month. The cured and markedly effective rate was 93.0% (40/43) in observation group, superior to that of 67.4% (29/43) in control group (P 0.05). The cured and markedly effective rate of damp retention and spleen deficiency: 93.8% (15/16) in observation group, superior to that of 60.0% (9/15) in control group (P cupping therapy is high pertinent and effective, the postherpetic neuralgia can be reduced significantly and the curative effect is superior to that of simple pricking and cupping.

    Radionecrosis (RN) in children treated for brain tumors represents a potentially severe long-term complication. Its diagnosis is challenging, since magnetic resonance imaging (MRI) cannot clearly discriminate between RN and tumor recurrence. A retrospective single-center study was undertaken to describe the incidence and clinical course of RN in a cohort of 107 children treated with external radiotherapy (RT) for various brain tumors between 1992 and 2012. During a median follow-up of 4.6 years (range 0.29-20.1 years), RN was implied by suspicious MRI findings in in 5 children (4.7 %), 5-131 months after RT. Suspicion was confirmed histologically (1 patient) or substantiated by FDG positron-emission tomography (FDG-PET, 2 patients) or by FDG-PET and MR spectroscopy (1 patient). Before developing RN, all 5 patients had received cytotoxic chemotherapy in addition to RT. In addition to standard treatment protocols, 2 patients had received further chemotherapy for progression or relapse. Median radiation dose expressed as the biologically equivalent total dose applied in 2 Gy fractions (EQD2) was 51.7 Gy (range 51.0-60.0 Gy). At RN onset, 4 children presented with neurological symptoms. Treatment of RN included resection (n = 1), corticosteroids (n = 2) and a combination of corticosteroids, hyperbaric oxygen (HBO) and bevacizumab (n = 1). One patient with asymptomatic RN was not treated. Complete radiological regression of the lesions was observed in all patients. Clinical symptoms normalized in 3 patients, whereas 2 developed permanent severe neurological deficits. RN represents a severe long-term treatment complication in children with brain tumors. The spectrum of clinical presentation is wide; ranging from asymptomatic lesions to progressive neurological deterioration. FDG-PET and MR spectroscopy may be useful for distinguishing between RN and tumor recurrence. Treatment options in patients with symptomatic RN include conservative management (steroids, HBO

    Full Text Available Abstract Background Lack of treatment initiation or intensification might explain why some patients with type 2 diabetes do not reach target goals. The objective is to assess trends in risk factor treatment, and identify determinants for medication adjustments in patients with uncontrolled hypertension and/or hyperlipidemia. Methods We conducted a cohort study using data from the Zwolle Outpatient Diabetes project Integrated Available Care (ZODIAC-study in The Netherlands. Management of hypertension and hyperlipidemia was assessed yearly from 1998–2004 by measuring the percentage of patients receiving a treatment initiation or intensification among all patients with elevated risk factor levels. Generalized estimating equation analyses were performed. Results During the study period, the percentage of patients with an elevated total cholesterol/high-density lipoproteins ratio (>6 decreased considerably (from 29% to 4% whereas the percentage of hypertensive patients decreased only slightly (≥ 150/85 mmHg; from 58% to 51%. Initiation of lipid-lowering therapy and intensification of antihypertensive therapy was higher in more recent years. However, still two-third of patients with insufficiently controlled blood pressure in 2003 did not receive an initiation or intensification of antihypertensive treatment in the following year. Treatment changes were mainly determined by elevated levels of the corresponding risk factor. We did not observe increased initiation rates for lipid-lowering therapy in patients with both hypertension and hyperlipidemia. Conclusion Hypertension and hyperlipidemia management in type 2 diabetes patients has improved in the past decade but further improvement is possible. Greater effort is needed to stimulate medication adjustments in patients with insufficiently controlled hypertension and combined risk factors.

    Background. Our aim was to investigate the association between migraine, tension type headache, and metabolic syndrome. Methods. Presence of tension type headache and migraine was investigated in 120 patients diagnosed as metabolic syndrome. The severity of the headache was recorded according to the visual analog scale. Results. Mean age of the patients was 54.41 ± 11.60 years (range, 29-84 yrs). Diagnoses of tension type headache and migraine without aura were made for 39 (32.5%) and 18 (15%) patients, respectively. Mean age of migraine patients was significantly lower relative to the patients with tension type headache and no headache. Incidence of hypertriglyceridemia was significantly higher in migraine patients when compared with cases tension type headache and without headache. In the tension type headache group, requirement for analgesics decreased as HDL cholesterol levels increased, while need for analgesic drugs increased in line with higher diastolic blood pressures. In the migraine group duration of headache was found to be prolonged with decreasing HDL cholesterol levels. Conclusion. In patients presenting with headache, its association with metabolic syndrome should be considered, and the patients should be especially observed with respect to response to analgesic and the presence of hypertension and hyperlipidemia.

    Full Text Available Abstract Background Early intramedullary nailing (IMN of long bone fractures in severely injured patients has been evaluated as beneficial, but has also been associated with increased inflammation, multi organ failure (MOF and morbidity. This study was initiated to evaluate the impact of primary femoral IMN on coagulation-, fibrinolysis-, inflammatory- and cardiopulmonary responses in polytraumatized patients. Methods Twelve adult polytraumatized patients with femoral shaft fractures were included. Serial blood samples were collected to evaluate coagulation-, fibrinolytic-, and cytokine activation in arterial blood. A flow-directed pulmonary artery (PA catheter was inserted prior to IMN. Cardiopulmonary function parameters were recorded peri- and postoperatively. The clinical course of the patients and complications were monitored and recorded daily. Results Mean Injury Severity Score (ISS was 31 ± 2.6. No procedure-related effect of the primary IMN on coagulation- and fibrinolysis activation was evident. Tumor necrosis factor alpha (TNF-α increased significantly from 6 hours post procedure to peak levels on the third postoperative day. Interleukin-6 (IL-6 increased from the first to the third postoperative day. Interleukin-10 (IL-10 peaked on the first postoperative day. A procedure-related transient hemodynamic response was observed on indexed pulmonary vascular resistance (PVRI two hours post procedure. 11/12 patients developed systemic inflammatory response syndrome (SIRS, 7/12 pneumonia, 3/12 acute lung injury (ALI, 3/12 adult respiratory distress syndrome (ARDS, 3/12 sepsis, 0/12 wound infection. Conclusion In the polytraumatized patients with femoral shaft fractures operated with primary IMN we observed a substantial response related to the initial trauma. We could not demonstrate any major additional IMN-related impact on the inflammatory responses or on the cardiopulmonary function parameters. These results have to be interpreted

  17. Depressive symptoms as a novel risk factor for recurrent venous thromboembolism: a longitudinal observational study in patients referred for thrombophilia investigation.

    Directory of Open Access Journals (Sweden)

    Roland von Känel

    Full Text Available BACKGROUND: Increasing evidence suggests that psychosocial factors, including depression predict incident venous thromboembolism (VTE against a background of genetic and acquired risk factors. The role of psychosocial factors for the risk of recurrent VTE has not previously been examined. We hypothesized that depressive symptoms in patients with prior VTE are associated with an increased risk of recurrent VTE. METHODS: In this longitudinal observational study, we investigated 271 consecutive patients, aged 18 years or older, referred for thrombophilia investigation with an objectively diagnosed episode of VTE. Patients completed the depression subscale of the Hospital Anxiety and Depression Scale (HADS-D. During the observation period, they were contacted by phone and information on recurrent VTE, anticoagulation therapy, and thromboprophylaxis in risk situations was collected. RESULTS: Clinically relevant depressive symptoms (HADS-D score ≥ 8 were present in 10% of patients. During a median observation period of 13 months (range 5-48, 27 (10% patients experienced recurrent VTE. After controlling for sociodemographic and clinical factors, a 3-point increase on the HADS-D score was associated with a 44% greater risk of recurrent VTE (OR 1.44, 95% CI 1.02, 2.06. Compared to patients with lower levels of depressive symptoms (HADS-D score: range 0-2, those with higher levels (HADS-D score: range 3-16 had a 4.1-times greater risk of recurrent VTE (OR 4.07, 95% CI 1.55, 10.66. CONCLUSIONS: The findings suggest that depressive symptoms might contribute to an increased risk of recurrent VTE independent of other prognostic factors. An increased risk might already be present at subclinical levels of depressive symptoms.

    To assess the performance of the Finnish Diabetes Risk Score (FINDRISC) questionnaire for detecting and predicting type 2 diabetes mellitus (DM2) in a Colombian population. This is a longitudinal observational study conducted in Floridablanca, Colombia. Adult subjects (age ≥ 35 years) without known diabetes, were included. A modified version of FINDRISC was completed, and the glycemia values from all the subjects were collected from the hospital's database. Firstly, a cross-sectional analysis was performed and then, the subsample of prediabetic participants was followed for diabetes incidence. A total of 772 subjects were suitable for the study. The overall prevalence of undiagnosed DM2 was 2.59%, and the incidence of DM2 among the prediabetic participants was 7.5 per 100 person-years after a total of 265257 person-years follow-up. The FINDRISC at baseline was significantly associated with undiagnosed and incident DM2. The area under receiver operating characteristics curve of the FINDRISC score for detecting undiagnosed DM2 in both men and women was 0.7477 and 0.7175, respectively; and for predicting the incidence of DM2 among prediabetics was 71.99% in men and 67.74% in women. The FINDRISC questionnaire is a useful screening tool to identify cross-sectionally unknown DM2 and to predict the incidence of DM2 among prediabetics in the Colombian population.

    Analysis of longitudinal data is often complicated by the presence of informative right censoring. This type of censoring should be accounted for in the analysis so that valid slope estimates are attained. In this study, we developed a new likelihood-based approach wherein the likelihood function is integrated over random effects to obtain a marginal likelihood function. Maximum likelihood estimates for the population slope were acquired by direct maximisation of the marginal likelihood function and empirical Bayes estimates for the individual slopes were generated using Gaussian quadrature. The performance of the model was assessed using the geometric and Poisson distributions to model the number of observations for every individual subject. Our model generated valid estimates for the slopes under both distributions with minimal bias and mean squared errors. Our sensitivity analysis confirmed the robustness of the model to assumptions pertaining to the underlying distribution and demonstrated its insensitivity to normality assumptions. Moreover, superiority of the model in terms of accuracy of slope estimates was consistently shown across the different levels of censoring in comparison to the naïve and bootstrap approaches. This model was illustrated using the cohort of renal transplant patients and estimates of the slopes that are adjusted for informative right censoring were acquired. © The Author(s) 2011.

    Relativistic viscous fluid dynamics (rRFD) has been highly sucessful in describing bulk observables of the QGP formed in ultra-relativistic heavy-ion collisions. However, vRFD requires an initial condition that is challenging to calculate from first-principles. Although reliable boost-invariant (2D) initial conditions are well developed, little is known about the longitudinal structures. We systematically study a parametric model for the initial 3D entropy distribution of the QGP formed in the collisions. We apply a cumulant generating function approach to parametrize the rapidity dependence of local entropy deposition as functions of participant densities, extending the 2D initial condition model TRENTo to 3D. This initial condition is integrated into a 3+1D ideal (for computational expediency) hydrodynamic model and a hadronic afterburner to calculate the centrality dependent charged particle pseudorapidity density and two-particle pseudorapidity correlation. Parameters are optimized by comparing to experimental measurements for p+Pb and Pb+Pb collisions using Bayesian inference. Finally, we use the calibrated model and a 3+1D viscous hybrid model to predict pseudorapidity dependent flows, event-plane decorrelations and flow correlations beyond mid-rapidity as a validation.

    There are fewer longitudinal studies from China on symptoms as described for the sick building syndrome (SBS). Here, we performed a two-year prospective study and investigated associations between environmental parameters such as room temperature, relative air humidity (RH), carbon dioxide (CO2), nitrogen dioxide (NO2), sulphur dioxide (SO2), ozone (O3), particulate matter (PM10), and health outcomes including prevalence, incidence and remission of SBS symptoms in junior high schools in Taiyuan, China. Totally 2134 pupils participated at baseline, and 1325 stayed in the same classrooms during the study period (2010-2012). The prevalence of mucosal symptoms, general symptoms and symptoms improved when away from school (school-related symptoms) was 22.7%, 20.4% and 39.2%, respectively, at baseline, and the prevalence increased during follow-up (P<0.001). At baseline, both indoor and outdoor SO2 were found positively associated with prevalence of school-related symptoms. Indoor O3 was shown to be positively associated with prevalence of skin symptoms. At follow-up, indoor PM10 was found to be positively associated with new onset of skin, mucosal and general symptoms. CO2 and RH were positively associated with new onset of mucosal, general and school-related symptoms. Outdoor SO2 was positively associated with new onset of skin symptoms, while outdoor NO2 was positively associated with new onset of skin, general and mucosal symptoms. Outdoor PM10 was found to be positively associated with new onset of skin, general and mucosal symptoms as well as school-related symptoms. In conclusion, symptoms as described for SBS were commonly found in school children in Taiyuan City, China, and increased during the two-year follow-up period. Environmental pollution, including PM10, SO2 and NO2, could increase the prevalence and incidence of SBS and decrease the remission rate. Moreover, parental asthma and allergy (heredity) and pollen or pet allergy (atopy) can be risk factors for

    It has been hypothesized that the relatively rare autosomal dominant Alzheimer disease (ADAD) may be a useful model of the more frequent, sporadic, late-onset AD (LOAD). Individuals with ADAD have a predictable age at onset and the biomarker profile of ADAD participants in the preclinical stage may be used to predict disease progression and clinical onset. However, the extent to which the pathogenesis and neuropathology of ADAD overlaps with that of LOAD is equivocal. To address this uncertainty, two multicenter longitudinal observational studies, the Alzheimer Disease Neuroimaging Initiative (ADNI) and the Dominantly Inherited Alzheimer Network (DIAN), leveraged the expertise and resources of the existing Knight Alzheimer Disease Research Center (ADRC) at Washington University School of Medicine, St. Louis, Missouri, USA, to establish a Neuropathology Core (NPC). The ADNI/DIAN-NPC is systematically examining the brains of all participants who come to autopsy at the 59 ADNI sites in the USA and Canada and the 14 DIAN sites in the USA (eight), Australia (three), UK (one) and Germany (two). By 2014, 41 ADNI and 24 DIAN autopsies (involving nine participants and 15 family members) had been performed. The autopsy rate in the ADNI cohort in the most recent year was 93% (total since NPC inception: 70%). In summary, the ADNI/DIAN NPC has implemented a standard protocol for all sites to solicit permission for brain autopsy and to send brain tissue to the NPC for a standardized, uniform and state-of-the-art neuropathologic assessment. The benefit to ADNI and DIAN of the implementation of the NPC is very clear. The NPC provides final "gold standard" neuropathological diagnoses and data against which the antecedent observations and measurements of ADNI and DIAN can be compared. © 2015 Japanese Society of Neuropathology.

    Polycystic ovary syndrome (PCOS) is associated with an increased risk of insulin resistance (IR), metabolic syndrome (MetS), impaired glucose tolerance (IGT) and type 2 diabetes mellitus (T2DM). Metabolic aspects of the four PCOS phenotypes remain to be fully defined. The aim of this study was to compare metabolic parameters and insulin resistance among the four PCOS phenotypes defined according to the Rotterdam criteria and to determine predictors of these complications. A total of 526 reproductive-aged women were included in this observational case-control study. Of these, 263 were diagnosed as a PCOS based on Rotterdam criteria and 263 infertile women with no evidence of PCOS were recruited as controls. Biochemical, metabolic and insulin resistance parameters were compared in the two groups and the frequency of MetS and IR were compared among the four phenotypes. Data were analyzed for statistical significance using Student's t-test and one way analysis of variance followed by a post-hoc test (least significant difference). Chi-square tests were used to compare proportions. Univariate and multivariate logistic regression analyses were also applied. IR was identified in 112 (42.6%) of the PCOS women and 45 (17.1%) of the control (P control groups. Women with oligo-anovulation (O) and PCO morphology (P) had a significantly lower level of 2-h postprandial insulin compared to women with O, P and hyperandrogenism (H) phenotypes. Logistic regression analysis showed that body mass index, waist circumference, triglyceride/high-density lipoprotein ratio (cardiovascular risk), HOMA-IR and glucose abnormalities (T2DM) were associated with increased risk of having MetS (P metabolic abnormalities. Although, there were no significant differences in IR, MetS and glucose intolerance between the four PCOS phenotypes, women with PCOS are at higher risk of impaired glucose tolerance and undiagnosed diabetes.

    Vascular involvement can be seen in up to 40% of patients with Behcet syndrome (BS), the lower-extremity vein thrombosis (LEVT) being the most common type. The aim of the current study was to compare venous Doppler findings and clinical features between BS patients with LEVT and control patients diagnosed as having LEVT due to other causes.All consecutive 78 patients (71 men, 7 women; mean age 38.6 ± 10.3 years) with LEVT due to BS and 50 control patients (29 men, 21 women; mean age 42.0 ± 12.5 years) who had LEVT due to other causes, or idiopathic, were studied with the help of a Doppler ultrasonography after a detailed clinical examination. Patterns of venous disease were identified by cluster analyses. Clinical features of chronic venous disease were assessed using 2 classification systems. Venous claudication was also assessed.Patients with BS were more likely to be men, had significantly earlier age of onset of thrombosis, and were treated mainly with immunosuppressives and less frequently with anticoagulants. Furthermore, they had significantly more bilateral involvement, less complete recanalization, and more frequent collateral formation. While control patients had a disorganized pattern of venous involvement, BS patients had a contiguous and symmetric pattern, involving all deep and superficial veins of the lower extremities, with less affinity for crural veins. Clinical assessment, as measured by the 2 classification systems, also indicated a more severe disease among the BS patients. In line, 51% of the BS patients suffered from severe post-thrombotic syndrome (PTS) and 32% from venous claudication, whereas these were present in 8% and 12%, respectively, among the controls. Among BS patients, a longer duration of thrombosis, bilateral femoral vein involvement, and using no anticoagulation along with immunosuppressive treatment when first diagnosed were found to be associated independently with severe PTS.Lower-extremity vein thrombosis

    Treatment with zoledronic acid (ZA) over 2 years, among 33 children with osteogenesis imperfecta (OI) and five Bruck syndrome cases, showed reduction in fracture rates, pain, and improvement in bone mineral density (BMD) and motor milestones of development. This is the first study reporting the use of bisphosphonates in patients with Bruck syndrome (BS). OI and BS are genetic disorders that result in bone fragility and reduced BMD. There is little literature describing the efficacy and safety of ZA in this population. In this study, we assess the response to treatment with ZA at six monthly intervals in Egyptian children with OI and BS for a period of 2 years. Thirty-three patients with OI and five patients with BS were treated with 0.1 mg/kg ZA intravenously every 6 months for 2 years during which they were followed up using different parameters. A clinical severity score (CSS) was applied to the patients before and 2 years after the start of therapy. Comparison of disease severity and response to ZA treatment between autosomal-dominant (AD) and autosomal-recessive (AR) OI patients was also done. After 6 months of treatment, OI and BS patients showed a significant increase in BMD Z-scores (P < 0.003 in the spine and P < 0.004 in the hip), together with a significant drop in fracture rate (P < 0.001), relief of pain (P < 0.001), and improvement in ambulation (P < 0.001). CSS was significantly reduced after 2 years of treatment in both OI and BS patients. AR-OI patients were more severely affected than AD-OI patients and showed more significant improvement. Zoledronic acid proved to be safe and effective in the treatment of OI and BS. The biannual infusion protocol was convenient to patients. There was a positive correlation between disease severity and benefits of the treatment. The use of the CSS proved to be of value in the assessment of the degree of severity in OI, and with some modifications, it was a valuable tool for the assessment of

    Full Text Available Background/Aims: LDL apheresis (LDL-A is used for drug-resistant nephrotic syndrome (NS as an alternative therapy to induce remission by improvement of hyperlipidemia. Several clinical studies have suggested the efficacy of LDL-A for refractory NS, but the level of evidence remains insufficient. A multicenter prospective study, POLARIS (Prospective Observational Survey on the Long-Term Effects of LDL Apheresis on Drug-Resistant Nephrotic Syndrome, was conducted to evaluate its clinical efficacy with high-level evidence. Methods: Patients with NS who showed resistance to primary medication for at least 4 weeks were prospectively recruited to the study and treated with LDL-A. The long-term outcome was evaluated based on the rate of remission of NS 2 years after treatment. Factors affecting the outcome were also examined. Results: A total of 58 refractory NS patients from 40 facilities were recruited and enrolled as subjects of the POLARIS study. Of the 44 subjects followed for 2 years, 21 (47.7% showed remission of NS based on a urinary protein (UP level Conclusions: Almost half of the cases of drug-resistant NS showed remission 2 years after LDL-A. Improvement of nephrotic parameters at termination of the LDL-A treatment was a predictor of a favorable outcome.

    The authors evaluated the prevalence and effect of the various tobacco use modalities among patients presenting with acute coronary syndrome (ACS) and compared them with non-tobacco and ex-tobacco users. An analysis of the 2nd Gulf Registry of Acute Coronary Events conducted between October 2008 and June 2009 and which included 7930 consecutive patients hospitalised with ACS was made. Patients initially were divided into non-tobacco users, ex-tobacco users and current tobacco users. Subanalysis according to the tobacco modality used was subsequently made: cigarette, waterpipe or smokeless tobacco users. Overall, 2834 (36%) patients were current tobacco users, 306 (3.9%) patients were waterpipe smokers and 240 patients (3%) were oral tobacco users. When compared with non-tobacco and ex-tobacco users, overall current tobacco users were younger, more likely to be male subjects and less likely to have diabetes mellitus, hypertension and dyslipidaemia. Mortality rate (p=0.001) and overall cardiovascular events (p=0.001) were lower among current tobacco users when compared with the other two groups. After adjustment for baseline variables, tobacco use was not an independent predictor of adverse events. Subset analysis demonstrates oral tobacco users and waterpipe smokers were older and more likely to be women when compared with cigarette smokers. Among the various tobacco groups, inhospital mortality rates were significantly higher among the waterpipe smokers when compared with the other two groups. Clinical characteristics and outcomes of ACS patients depend on the tobacco modality used. Further studies are required to evaluate the impact of emerging tobacco use modalities on patients with coronary artery disease.

    To investigate the effect of intravenous (IV) iron (500 mg ferric carboxymaltose [FCM] as a single dose) on restless legs syndrome (RLS) severity on a day-to-day basis. Twenty patients with RLS and absolute or functional iron deficiency or low normal serum ferritin (<45 μg/l) were included. Change of RLS severity was evaluated using the International RLS severity scale (IRLS) and the RLS-severity diary (RLS-SD) which evaluates symptom severity over a 6-h period on an 11-point numerical Likert scale, four times a day. Twelve patients reported that IV FCM improved RLS ("responders"). IRLS score decreased from 30.1 (± 5.9) to 23.07 (± 9.5) (p=0.001) in the whole group and from 28.3 (± 6.1) to 18.3 (± 8.0) (p=0.002) in the responder group three weeks after IV FCM treatment. A clinically relevant effect of IV iron on RLS severity could be seen as early as day eight. The responder group differed from the non-responder group in tendency by being younger (p=0.064), having a lower serum ferritin level at baseline (p=0.097), and presenting a lower number of comorbid conditions. FCM led to a considerable improvement in RLS in the responder group within about one week. These findings are clinically relevant, especially for patients with severe RLS symptoms and iron deficiency, since a change or uptitration of RLS-specific medication can be avoided or postponed in these patients due to the rapid response to IV FCM treatment.

    Electronic cigarettes (e-cigarettes) are purported to deliver nicotine aerosol without any toxic combustion products present in tobacco smoke. In this longitudinal within-subjects observational study, we evaluated the effects of e-cigarettes on nicotine delivery and exposure to selected carcinogens and toxicants. We measured seven nicotine metabolites and 17 tobacco smoke exposure biomarkers in the urine samples of 20 smokers collected before and after switching to pen-style M201 e-cigarettes for 2 weeks. Biomarkers were metabolites of 13 major carcinogens and toxicants in cigarette smoke: one tobacco-specific nitrosamine (NNK), eight volatile organic compounds (1,3-butadiene, crotonaldehyde, acrolein, benzene, acrylamide, acrylonitrile, ethylene oxide, and propylene oxide), and four polycyclic aromatic hydrocarbons (naphthalene, fluorene, phenanthrene, and pyrene). Changes in urine biomarkers concentration were tested using repeated measures analysis of variance. In total, 45% of participants reported complete abstinence from cigarette smoking at 2 weeks, while 55% reported continued smoking. Levels of total nicotine and some polycyclic aromatic hydrocarbon metabolites did not change after switching from tobacco to e-cigarettes. All other biomarkers significantly decreased after 1 week of using e-cigarettes (p e-cigarettes, nicotine exposure remains unchanged, while exposure to selected carcinogens and toxicants is substantially reduced. To our knowledge, this is the first study that demonstrates that substituting tobacco cigarettes with an e-cigarette may reduce user exposure to numerous toxicants and carcinogens otherwise present in tobacco cigarettes. Data on reduced exposure to harmful constituents that are present in tobacco cigarettes and e-cigarettes can aid in evaluating e-cigarettes as a potential harm reduction device. © The Author 2016.

    The Merseburg triad (hyperthyroidism, goiter, and orbitopathy) characterizes classical description of Graves' disease (GD). Aim of this observational, longitudinal study was to evaluate the current clinical features of newly diagnosed GD in Italy. In two Northern Italy centers (Varese and Pavia), 283 consecutive patients (211 women, 72 men; mean age 47.4 years) with newly diagnosed GD were recruited in the years 2010-2014. Diagnosis was based on established criteria, and thyroid volume was assessed by ultrasonography. A clinical severity score (CSS) to assess the overall disease severity was developed by grading each component of the Merseburg triad. At diagnosis, 45 % of patients had no goiter, and 30 % had a small goiter. The proportion of goitrous patients was much lower than in two Italian studies performed 20-30 years ago. Hyperthyroidism was subclinical in 16 % and mild in 29 % of patients, and Graves' orbitopathy was present in 20 %, usually mild, and active in only 2.5 % of patients. Using the CSS, less than half (44 %) of the patients had severe GD, while 22 % had mild and 34 % moderate disease. CSS was associated with a significantly higher risk of poorly controlled hyperthyroidism at 6 months. In Italy, a relevant proportion of Graves' patients at diagnosis have mild to moderate GD; about half of them have no goiter, slightly less than one-fifth have subclinical hyperthyroidism, and only 20 % have GO. Thus, the clinical phenotype of GD is milder than in the past, possibly due to both earlier diagnosis and treatment, and improved iodine nutrition.

    Clinicians' current practice patterns in the management of acute respiratory distress syndrome (ARDS) and refractory hypoxemia are not well described. To describe mechanical ventilation strategies and treatment adjuncts for adults with ARDS, including refractory hypoxemia. This was a prospective cohort study (March 2014-February 2015) of mechanically ventilated adults with moderate-to-severe ARDS requiring an Fi O 2 of 0.50 or greater in 24 intensive care units. We enrolled 664 patients: 222 (33%) with moderate and 442 (67%) with severe ARDS. On Study Day 1, mean Vt was 7.5 (SD = 2.1) ml/kg predicted body weight (n = 625); 80% (n = 501) received Vt greater than 6 ml/kg. Mean positive end-expiratory pressure (PEEP) was 10.5 (3.7) cm H 2 O (n = 653); 568 patients (87%) received PEEP less than 15 cm H 2 O. Treatment adjuncts were common (n = 440, 66%): neuromuscular blockers (n = 276, 42%), pulmonary vasodilators (n = 118, 18%), prone positioning (n = 67, 10%), extracorporeal life support (n = 29, 4%), and high-frequency oscillatory ventilation (n = 29, 4%). Refractory hypoxemia, defined as Pa O 2 less than 60 mm Hg on Fi O 2 of 1.0, occurred in 138 (21%) patients. At onset of refractory hypoxemia, mean Vt was 7.1 (SD = 2.0) ml/kg (n = 124); 95 patients (77%) received Vt greater than 6 ml/kg. Mean PEEP was 12.1 (SD = 4.4) cm H 2 O (n = 133); 99 patients (74%) received PEEP less than 15 cm H 2 O. Among patients with refractory hypoxemia, 91% received treatment adjuncts (126/138), with increased use of neuromuscular blockers (n = 87, 63%), pulmonary vasodilators (n = 57, 41%), and prone positioning (n = 32, 23%). Patients with moderate-to-severe ARDS receive treatment adjuncts frequently, especially with refractory hypoxemia. Paradoxically, therapies with less evidence supporting their use (e.g., pulmonary vasodilators) were over-used, whereas those with more evidence (e.g., prone positioning

    The objective of this study was to estimate resource consumption and direct healthcare costs of patients with a first hospitalization for acute coronary syndrome (ACS) in 2008 in the Piedmont Region, Italy. Subjects hospitalized with a first episode of ACS in 2008 were selected from the regional hospital discharge database. All hospitalizations, drug prescriptions, and outpatient episodes of care in the 12 months following discharge were considered to estimate resource consumption and direct healthcare costs from the Piedmont Regional Health Service perspective. The analysis was carried out separately for ST-elevation myocardial infarction (STEMI), non-ST-elevation myocardial infarction (NSTEMI), and unstable angina (UA) populations. In the accrual period, 7765 subjects (1.75‰ of the total population) were hospitalized for ACS (64.2% men). The average age was 66.5 for men and 75.4 for women. The average in-hospital mortality was 6.5% (n = 508). The total ACS population was classified as: STEMI 45.2%, NSTEMI 29.4%, and UA 25.4%. The average yearly costs per patient alive at the end of follow-up (n = 6851) were 14,160.8&OV0556; (18,678.7 USD): 83.9% for inpatient admissions [11,881.2&OV0556; (15,671.8 USD)], 9.3% for drugs [1311.6&OV0556; (1730.1 USD)], 5.0% for diagnostic and therapeutic procedures and outpatient visits [708.2&OV0556; (934.1 USD)], and 1.8% for 1-day hospital stays [259.8&OV0556; (342.7 USD)]. The average yearly direct healthcare costs by ACS event were 14,984.5&OV0556; (19,765.2 USD) for STEMI, 14,554.1&OV0556; (19,197.4 USD) for NSTEMI, and 12,481.5&OV0556; (16,463.6 USD) for UA. In each subpopulation, costs were significantly higher for men than for women. ACS imposes a significant burden in terms of morbidity and mortality and generates major public health service costs.

    To analyze the prevalence, characteristics and outcome of cystic lung disease associated with Sjögren's syndrome (SS). From June 2010 to February 2015, 90 consecutive SS patients [60.1±14.8years; 88 (97.8%) female, 75 (83.3%) primary SS] had a systematic chest CT-scan. The presence of thin-walled cysts was analyzed by one experienced radiologist. Demographic data, clinical history, laboratory findings, and pulmonary function tests were extracted retrospectively from medical records. Twenty-one (23.3%) patients had cysts on CT scan performed 40.5±54.5months after SS diagnosis. Cysts number ranged from 1 to 25 were often bilateral (52.4%) and mostly located in the middle lung zone (76.2%). Cysts were isolated (n=6, 28.6%) or associated with other lesions, including bronchiectasis (n=5, 23.8%), micronodules (n=5, 23.8%), ground-glass opacity (n=4, 19%) and/or air trapping (n=3, 14.3%). Most patients with cysts (57.1%) had no respiratory symptoms. When comparing SS patients with and without cysts, patients with cysts tended to be older (65.3±15.3 versus 58.5±14.4years, P=0.06). Smoking habits were similar in both groups. Anti-SSB antibodies were more frequently detected in patients with cysts (57.1% vs. 26.1%, P=0.02). Pulmonary function tests were normal or displayed only mild small airways obstruction and reduced diffusion capacity to carbon monoxide. Four (19%) patients with cysts had a past history of associated pulmonary disease, including interstitial lung disease. During follow-up (25.1±17.7months), no patient developed specific lung disease or lymphoproliferative disorders. Cystic lung disease is frequent, benign, associated with anti-SSB/La antibodies and has no impact on outcome in SS. Copyright © 2016 Société française de rhumatologie. Published by Elsevier SAS.

    We examined the risk of cardiovascular disease, stroke, ischaemic heart disease, and diabetes with the metabolic syndrome according to the new harmonised definition and its components using a national longitudinal data set from an Asian population. Data of 9791 men and women aged 20+ from 1998 and 2001 Korea National Health and Nutrition Examination Surveys were individually linked to national hospitalisation and mortality data using unique personal identification numbers. During a 5.8-year follow-up through 2005, 288 incident cardiovascular events (184 strokes and 122 cases of ischaemic heart disease) and 85 new diabetes cases have been detected. Men and women with the metabolic syndrome had 48%, 39%, 64%, and 127% greater risks of cardiovascular disease, stroke, ischaemic heart disease, and diabetes, respectively, than those without the metabolic syndrome. The increased risks of cardiovascular disease, ischaemic heart disease, and diabetes remained significant after adjusting for health behaviours, bio-clinical factors, family history, and socio-demographic factors. Analysis results on population attributable risks showed that about a quarter of total diabetes occurrence and more than 10% of cardiovascular disease was attributable to the metabolic syndrome. The number of metabolic syndrome components was linearly associated with risks of outcomes. High blood pressure was significantly associated with all four outcomes while hypertriglyceridemia and hyperglycemia were also important for ischaemic heart disease and diabetes, respectively. Reduction of metabolic risk factors is necessary in South Korea to lower the burden of associated diseases, especially ever-increasing ischaemic heart disease and diabetes.

    There are limited data on the effects of trastuzumab on the right ventricle (RV). Therefore, we sought to evaluate the temporal changes in right ventricular (RV) structure and function as measured by cardiovascular magnetic resonance (CMR), and their relationship with left ventricular (LV) structure and function in breast cancer patients treated with trastuzumab. Prospective, longitudinal, observational study involving 41 women with HER2+ breast cancer who underwent serial CMR at baseline, 6, 12, and 18 months after initiation of trastuzumab. A single blinded observer measured RV parameters on de-identified CMRs in a random order. Linear mixed models were used to investigate temporal changes in RV parameters. Of the 41 women (age 52 ± 11 years), only one patient experienced trastuzumab-induced cardiotoxicity. Compared to baseline, there were small but significant increases in the RV end-diastolic volume at 6 months (p = 0.002) and RV end-systolic volume at 6 and 12 months (p < 0.001 for both), but not at 18 months (p = 0.82 and 0.13 respectively). RV ejection fraction (RVEF), when compared to baseline (58.3%, 95% CI 57.1-59.5%), showed corresponding decreases at 6 months (53.9%, 95% CI 52.5-55.4%, p < 0.001) and 12 months (55%, 95% CI 53.8-56.2%, p < 0.001) that recovered at 18 months (56.6%, 95% CI 55.1-58.0%, p = 0.08). Although the temporal pattern of changes in LVEF and RVEF were similar, there was no significant correlation between RVEF and LVEF at baseline (r = 0.29, p = 0.07) or between their changes at 6 months (r = 0.24, p = 0.17). In patients receiving trastuzumab without overt cardiotoxicity, there is a subtle but significant deleterious effect on RV structure and function that recover at 18 months, which can be detected by CMR. Furthermore, monitoring of LVEF alone may not be sufficient in detecting early RV injury. These novel findings provide further support for CMR in monitoring early

    Co-existence of Asperger syndrome (AS) and non-verbal learning disability (NLD) has been proposed based on the observation that people with AS tend to have significantly higher verbal than performance IQ (VIQ > PIQ by ≥ 15 points), one of the core features of NLD. In the present study we examined neuropsychological and social adaptive profiles with "non-verbal learning problems" associated with NLD in a group of individuals with AS followed from childhood into early adult life. The group was divided into three subgroups: (i) persistent NLD (P-NLD), i.e. NLD (VIQ > PIQ) both in childhood and early adulthood occasions, (ii) childhood NLD (CO-NLD), i.e. NLD (VIQ > PIQ) only at original diagnosis, or (iii) No NLD (VIQ > PIQ) ever (NO-NLD). All three subgroups were followed prospectively from childhood into adolescence and young adult life. One in four to one in five of the whole group of males with AS had P-NLD. The P-NLD subgroup had poorer neuropsychological outcome in early adult life than did those with CO-NLD and those with NO-NLD. There were no unequivocal markers in early childhood that predicted subgroup status in early adult life, but early motor delay and a history of early speech-language problems tended to be associated with P-NLD. © 2013 Elsevier Ireland Ltd.

Different reports have disclosed the association between sleep and cognition in adults and in children, as well as the impact of disturbed sleep on various aspects of neuropsychological functioning and behavior in children and adolescents. Behavioral and cognitive dysfunctions can also be considered as related to alterations in the executive functions (EF system. In particular, the EF concept refers to self-regulatory cognitive processes that are associated with monitoring and controlling both thought and goal directed behaviors. The aim of the present study is to assess the impact of the obstructive sleep apnea syndrome (OSAS on EF in a large sample of school aged children. Materials and methods: The study population comprised 79 children (51 males and 28 females aged 7–12 years (mean 9.14 ± 2.36 years with OSAS and 92 healthy children (63 males and 29 females, mean age 9.08 ± 2.44 years. To identify the severity of OSAS, an overnight respiratory evaluation was performed. All subjects filled out the Italian version of the Modified Card Sorting Test to screen EFs. Moreover, to check the degree of subjective perceived daytime sleepiness

    Full Text Available AIMS: To clarify predictive values of C-reactive protein (CRP and high-molecular-weight (HMW adiponectin for development of metabolic syndrome. RESEARCH DESIGN AND METHODS: We conducted a prospective cohort study of Japanese workers who had participated in an annual health checkup in 2007 and 2011. A total of 750 subjects (558 men and 192 women, age 46±8 years who had not met the criteria of metabolic syndrome and whose CRP and HMW-adiponectin levels had been measured in 2007 were enrolled in this study. Associations between CRP, HMW-adiponectin and development of metabolic syndrome after 4 years were assessed by logistic regression analysis and their predictive values were compared by receiver operating characteristic analysis. RESULTS: Among 750 subjects, 61 (8.1% developed metabolic syndrome defined by modified National Cholesterol Education Program Adult Treatment Panel III (NCEP-ATP III criteria and 53 (7.1% developed metabolic syndrome defined by Japan Society for the Study of Obesity (JASSO in 2011. Although CRP and HMW-adiponectin were both significantly correlated with development of metabolic syndrome, multivariate logistic regression analysis revealed that HMW-adiponectin but not CRP was associated with metabolic syndrome independently of BMI or waist circumference. Adding these biomarkers to BMI or waist circumference did not improve the predictive value for metabolic syndrome. CONCLUSION: Our findings indicate that the traditional markers of adiposity such as BMI or waist circumference remain superior markers for predicting metabolic syndrome compared to CRP, HMW-adiponectin, or the combination of both among the Japanese population.

    The association between educational status and 10-year risk for acute coronary syndrome (ACS) and all-cause mortality was evaluated. From October 2003 to September 2004, 2172 consecutive ACS patients from six Greek hospitals were enrolled. In 2013 to 2014, a 10-year follow-up (2004-2014) assessment was performed for 1918 participants (participation rate, 88%). Each patient's educational status was classified as low (14 years). Overall all-cause mortality was almost twofold higher in the low-education group than in the intermediate-education and high-education groups (40% vs. 22% and 19%, respectively, peducation group than in the intermediate-education and high-education groups (42% vs. 30% and 35%, peducation on the investigated outcomes were observed. Moreover, patients in the high-education group were more physically active, had a better financial status, and were less likely to have hypertension, diabetes, or ACS than the participants with the least education (peducational status with all-cause mortality and ACS events were observed. A U-shaped association may be proposed for the relationship between ACS prognosis and educational status, with participants in the low-education and high-education groups being negatively affected by other factors (e.g., job stress, depression, or loneliness). Public health policies should be aimed at specific social groups to reduce the overall burden of cardiovascular disease morbidity.

    Aspirin is the most widely used antiplatelet drug postmyocardial infarction, yet its optimal maintenance dose after percutaneous coronary intervention with stenting remains uncertain. We compared outcomes of 10 213 patients with myocardial infarction who underwent percutaneous coronary intervention and were discharged on dual-antiplatelet therapy at 228 US hospitals in the Treatment with ADP Receptor Inhibitors: Longitudinal Assessment of Treatment Patterns and Events after Acute Coronary Syndrome (TRANSLATE-ACS) study from 2010 to 2012. Major adverse cardiovascular events and bleeding within 6 months postdischarge were compared between high-dose (325 mg) and low-dose aspirin (81 mg) by using regression models with inverse probability-weighted propensity adjustment. Overall, 6387 patients (63%) received high-dose aspirin at discharge. Major adverse cardiovascular events risk was not significantly different between groups (high versus low: unadjusted 8.2% versus 9.2%; adjusted hazard ratio, 0.99; 95% confidence interval, 0.85-1.17). High-dose aspirin use was associated with greater risk of any Bleeding Academic Research Consortium-defined bleeding events (unadjusted 24.2% versus 22.7%; adjusted odds ratio, 1.19; 95% confidence interval, 1.06-1.33), driven mostly by minor Bleeding Academic Research Consortium type 1 or 2 bleeding events not requiring hospitalization (unadjusted 21.4% versus 19.5%; adjusted odds ratio, 1.19; 95% confidence interval, 1.05-1.34). Bleeding events requiring hospitalization were similar by aspirin dosing groups (unadjusted 2.8% versus 3.2%, adjusted odds ratio, 1.22; 95% confidence interval, 0.87-1.70). Similar associations were observed in landmark analyses accounting for aspirin dosing change over time, and across subgroup analyses by age, sex, baseline aspirin use, and type of ADP receptor inhibitor (clopidogrel versus prasugrel/ticagrelor). Among percutaneous coronary intervention-treated patients with myocardial infarction, high

    This study sought to describe the short- and long-term (up to 2 years) antithrombotic management patterns in a real-life setting for patients hospitalized for an acute coronary syndrome (ACS) event, and to document clinical outcomes. EPICOR-RUS was a multicenter (34 centers), prospective, observational, longitudinal cohort study conducted across Russia on antithrombotic management in hospitalized (within 24 hours of symptom onset) ACS patients with 2 year follow-up. NCT01373957. A total of 600 ACS patients (71.1% male, mean age 60 years) were enrolled; 599 were included for analysis. Diagnosis comprised STEMI (n = 375, 62.6%), NSTEMI (n = 147, 24.5%), and unstable angina (UA) (n = 77, 12.9%). Percutaneous coronary intervention (PCI) was conducted in 64.3% of patients with STEMI (with or without thrombolysis), 36.7% with NSTEMI, and 58.4% with UA. There was undertreatment with dual antiplatelet therapy (DAPT) for STEMI, NSTEMI, and UA: 14.7%, 25.9% and 16.9% of patients, respectively, were not receiving DAPT during hospitalization, and 10.1%, 21.8% and 16.9% at discharge. Post-discharge, of the STEMI group, only 72.4% of patients who were managed by PCI and 39.8% of conservatively treated patients received DAPT at 12 months. The respective figures in the NSTEMI group were 77.3% and 26.4%. In the STEMI cohort the cumulative incidence of all-cause mortality was 3.2% at 1 year and 5.1% at 2 years of follow-up; in the NSTEMI cohort this was 2.7% and 4.8%, respectively. There were no deaths by 12 months and one death by 24 months (1.3%) in the UA population. Despite evidence-based guidelines for the management of ACS, the real-world setting in Russia shows discrepancies in clinical practice, highlighting the need for improvements for the optimal management of high-risk patients with ACS.

    Identifying ankylosing spondylitis (AS) patients who are likely to benefit from tumor necrosis factor-alpha (TNF-α) blocking therapy is important, especially in view of the costs and potential side effects of these agents. Recently, the AS Disease Activity Score (ASDAS) has been developed to assess both subjective and objective aspects of AS disease activity. However, data about the predictive value of the ASDAS with respect to clinical response to TNF-α blocking therapy are lacking. The aim of the present study was to identify baseline predictors of response and discontinuation of TNF-α blocking therapy in AS patients in daily clinical practice. AS outpatients who started TNF-α blocking therapy were included in the Groningen Leeuwarden Ankylosing Spondylitis (GLAS) study, an ongoing prospective longitudinal observational cohort study with follow-up visits according to a fixed protocol. For the present analysis, patients were excluded if they had previously received anti-TNF-α treatment. Predictor analyses of response and treatment discontinuation were performed using logistic and Cox regression models, respectively. Between November 2004 and April 2010, 220 patients started treatment with infliximab (n = 32), etanercept (n = 137), or adalimumab (n = 51). At three and six months, 68% and 63% of patients were Assessments in Ankylosing Spondylitis (ASAS)20 responders, 49% and 46% ASAS40 responders, and 49% and 50% Bath Ankylosing Spondylitis Disease Activity Index (BASDAI)50 responders, respectively. Baseline predictors of response were younger age, male gender, higher ASDAS score, higher erythrocyte sedimentation rate (ESR) level, higher C-reactive protein (CRP) level, presence of peripheral arthritis, higher patient's global assessment of disease activity, and lower modified Schober test. In August 2010, 64% of patients were still using their TNF-α blocking agent with a median follow-up of 33.1 months (range 2.4 to 68.2). Baseline predictors of

    Objective: To describe corneal alterations visible on in vivo confocal microscopy in patients with debilitating ocular sequelae caused by Stevens-Johnson syndrome (SJS) or toxic epidermal necrolysis (TEN). Methods: Twenty-two eyes of 11 consecutive patients suffering from chronic SJS or TEN were studied using slit lamp and in vivo confocal microscopy in the Ophthalmology Outpatient Department of Peking Union Medical College Hospital from March 2014 to April 2015. Results: Dry eye with meibomian gland dysfunction (19 eyes of 10 patients, 86.4%) was the most frequent clinical sequelae. Two patients (3 eyes, 13.6%) had severe vison loss with corneal neovascularization and conjunctivization. One patient had asymmetric binocular disease. Corneal epithelial cells were observed at an active state in 10 patients (19 eyes, 86.4%) and corneal stromal cells at an active state in all patients (22 eyes, 100%). Twenty eyes (10 patients, 91%) were noted with abnormal nerve layout and 10 eyes (5 patients, 45.5%) with dendritic cell infiltration around pathological nerve damages. Numerous inflammory cells were observed in 6 eyes (3 patients, 27.3%). Conclusions: The corneas of patients with chronic ocular sequelae associated with SJS or TEN present a number of abnormalities. In vivo confocal microscopy is a potetial useful tool for therapeutic indications and for follow-up of the debilitating chronic ocular problems linked to SJS and TEN.

    Studies have demonstrated that abnormalities in interferon regulatory factor-1 (IRF-1) expression might develop myelodysplastic syndromes (MDS). IRF-1 was described as modulator of T regulatory (Treg) cells by suppressing Foxp3 on mice. We aimed to determine the role of Treg and IRF-1 in MDS. Thirty-eight MDS patients fulfilling WHO criteria and classified according to risk scores were evaluated at time 0 (T0) and after 12 months (T12) for: Treg suppression activity in coculture with T effector (Teff) cells; IRF-1 and Foxp3 genetic expression by qRT-PCR; IL-2, -4, -6, -10, -17, TNFα and IFNγ production by Cytometric Bead Array. No differences in Foxp3 expression (T0=0.06±0.06 vs T12=0.06±0.12, p=0.5), Treg number (T0=5.62±2.84×10 5 vs T12=4.87±2.62×10 5 ; p=0.3) and Teff percentage (T0=16.8±9.56% vs T12=13.1±6.3%; p=0.06) were observed on T12. Low risk MDS patients showed a higher number of Treg (5.2±2.6×10 5 ) versus high risk group (2.6±1.2×10 5 , p=0.03). Treg suppression activity was impaired on T0 and T12.Cytokine production and IRF-1 expression were increased on T12. The correlation between IRF-1 and FoxP3 was negative (r 2 =0.317, p=0.045) on T0. These results suggest a hyper activity of the immune system, probably secondary to Treg suppression activity impairment. This state may induce the loss of tolerance culminating in the proliferation of MDS clones. Copyright © 2017 Elsevier Ltd. All rights reserved.

    To measure the intracompartmental pressures surrounding tibial fractures not exhibiting any clinical evidence of compartment syndrome. Our hypothesis was that pressures often exceed the recommended threshold of fasciotomy despite the absence of compartment syndrome, and hence diagnosis based on pressure measurements alone is unreliable. Thirteen consecutive patients with closed tibial shaft fractures without clinical suspicion of compartment syndrome, and who were planned for intramedullary nailing, were prospectively enrolled. Compartment pressures ( P) in all four compartments of the affected leg were measured at the start of surgery and immediately after tibial reaming, and differential pressures (delta P) were calculated based on the diastolic blood pressure prior to induction of anaesthesia. No patients required reoperation in the post-operative period, as a result of an undiagnosed compartment syndrome. Using commonly quoted threshold pressure criteria, 62% (using P > 30 mmHg) and 23% of patients (using delta P compartment syndrome. We conclude that raised compartment pressures are frequently seen in patients with tibial shaft fractures; but in most cases, it does not equate to the presence of compartment syndrome. Diagnosis of compartment syndrome based on intracompartmental pressure measurements alone may result in unnecessary fasciotomies in a sizeable number of patients. Compartment syndrome remains a clinical diagnosis, and one which always needs to be considered when managing tibial fractures.

    Full Text Available Objectives: The association between educational status and 10-year risk for acute coronary syndrome (ACS and all-cause mortality was evaluated. Methods: From October 2003 to September 2004, 2172 consecutive ACS patients from six Greek hospitals were enrolled. In 2013 to 2014, a 10-year follow-up (2004-2014 assessment was performed for 1918 participants (participation rate, 88%. Each patient’s educational status was classified as low (14 years. Results: Overall all-cause mortality was almost twofold higher in the low-education group than in the intermediate-education and high-education groups (40% vs. 22% and 19%, respectively, p<0.001. Additionally, 10-year recurrent ACS events (fatal and non-fatal were more common in the low-education group than in the intermediate-education and high-education groups (42% vs. 30% and 35%, p<0.001, and no interactions between sex and education on the investigated outcomes were observed. Moreover, patients in the high-education group were more physically active, had a better financial status, and were less likely to have hypertension, diabetes, or ACS than the participants with the least education (p<0.001; however, when those characteristics and lifestyle habits were accounted for, no moderating effects regarding the relationship of educational status with all-cause mortality and ACS events were observed. Conclusions: A U-shaped association may be proposed for the relationship between ACS prognosis and educational status, with participants in the low-education and high-education groups being negatively affected by other factors (e.g., job stress, depression, or loneliness. Public health policies should be aimed at specific social groups to reduce the overall burden of cardiovascular disease morbidity.

    We evaluated carotid intima-media thickness (CIMT) as an early marker of atherosclerosis, as well as its main determinants among androgen excess, obesity and insulin resistance, in patients with polycystic ovary syndrome (PCOS). We selected 40 PCOS patients and 20 non-hyperandrogenic women who were similar in terms of age and grade of obesity. Complete clinical, metabolic and hormonal profiles and left common CIMT measurements were obtained. Patients with PCOS presented with increased mean CIMT values when compared with controls (F = 8.575; P = 0.005), and this was independent of obesity. Five PCOS patients but no controls had increased CIMT values. CIMT correlated directly with serum total and free testosterone, androstenedione and dehydroepiandrosterone-sulfate levels and mean 24-h heart rate (HR), and inversely with the insulin sensitivity index (ISI), but no correlation was observed with the body mass index (BMI). Multiple stepwise linear regression models showed that in PCOS patients, the main determinants of CIMT were serum total testosterone or androstenedione concentrations, with no influence of ISI or the mean 24-h HR. Compared with control women, PCOS patients present with an increased CIMT, independent of obesity and related directly to androgen excess; this suggests that hyperandrogenism is associated with atherosclerosis and cardiovascular risk in these women.

    Some statins, such as atorvastatin, have proven renoprotective effects. The comparative renoprotective potential of simvastatin is less clear. This study aimed to compare the renoprotective effects of simvastatin with atorvastatin in patients with acute coronary syndrome (ACS) undergoing percutaneous coronary intervention (PCI). This observational study examined the medical records of 271 patients who were treated at the Guangdong Cardiovascular Institute from April 2004 to February 2008. Patients had received either 40 mg simvastatin (n = 128) or 20 mg atorvastatin (n = 143), daily, for a period of at least 6 months following PCI. Declined renal function (DRF) was defined at the occurrence of chronic kidney disease (CKD) or elevated CKD stages at 6-months post-PCI. Results showed that the incidence of DRF was similar among patients taking simvastatin or atorvastatin (25.00% vs 26.57%, respectively). Kaplan-Meier survival analysis showed that patients who developed DRF had a higher incidence of mortality and major adverse cardiovascular events (MACEs) than those without DRF (17.41% vs 28.57%, P = .0308). Multivariate logistic regression analysis identified diabetes and baseline estimated glomerular filtration rate as independent risk factors for DRF. Collectively, our results indicate that simvastatin has comparable renoprotective effects to atorvastatin in ACS patients undergoing PCI. Further studies are warranted to confirm the comparative renoprotective effects of statins.

    To evaluate the efficacy, safety, and tolerability of lacosamide in adults with LGS in the clinical setting. The present report is a retrospective, open-label treatment study carried out from June 2013 to December 2014 at the National Institute of Colombia. Lacosamide was introduced as add-on therapy. All caregivers were instructed to initiate lacosamide at low doses (25-50 mg) and gradually increasing it every 2 weeks. The efficacy was evaluated based on the reduction in the rate of each countable type of seizure. We also evaluated the retention rate for lacosamide as the number of days with lacosamide during follow-up. The tolerability was evaluated base on account the adverse events. We found that lacosamide only improves the seizure rate in three out of 19 patients with LGS, in two of them by more than 50%. The highest seizure reduction rate was observed in the focal and tonic-clonic seizures. The most commonly reported adverse events were worsening of seizures, aggressiveness and irritability. Nine patients (47.4%) showed worsening of their behavior during the treatment with lacosamide. Lacosamide can exacerbate both, the tonic and astatic seizures, and the encephalopathy associated with this epileptic syndrome. However, it is interesting to consider the likelihood of suppression of generalized tonic-clonic and focal seizures. That is why; lacosamide could be an option after carefully balancing risks and benefits in each individual case. Copyright © 2015 British Epilepsy Association. Published by Elsevier Ltd.

    To observe the clinical effect of cupping combined with acupuncture stimulation of trigger points on lumbar myofascial pain syndrome (MPS). Sixty MPS patients were randomly divided into acupuncture + TDP group (n = 30), and cupping + acupuncture group (n = 30). Patients in the acupuncture + TDP group were treated by acupuncture stimulation of trigger points and local TDP irradiation, and patients of the cupping + acupuncture group treated by intensive cupping applied to the myofascial band and acupuncture stimulation of the locus according to the position of muscular tension band. The therapeutic effects were assessed according to the score of the McGill pain questionnaire composing of pain rating index (PRI), visual analogue scale (VAS) and present pain intensity (PPI) before, immediately and 1 month after the treatment. After the treatment, the total effective rates of the acupuncture+ TDP and cupping + acupuncture groups were 83.3% (25/30) and 96.6% (29/30), respectively, without significant difference between the two groups (P > 0.05). One month's follow-up showed that the total effective rates of the acupuncture + TDP and cupping + acupuncture groups were 40.0% and 90.0% respectively, and the latter group was significantly better than the acupuncture + TDP group in the therapeutic effect (P cupping + acupuncture group were obviously lower than those of the acupuncture group (P cupping plus acupuncture can effectively relieve pain in MPS patients, while the therapeutic effect of cupping plus acupuncture treatment lasts longer analgesic effect.

    Malnutrition-Inflammation-Atherosclerosis (MIA) factors significantly and independently affect life prognosis of hemodialysis (HD) patients. We re-evaluated Japanese data, which have progressed ahead from a community-based observational study. The present study was designed to assess the contribution of these MIA factors to the mortality rate of Japanese HD patients in a community of 1.8 million people over a 36-month follow-up period. A total of 5813 patients at 76 facilities were on maintenance HD in the Kumamoto Prefecture. Specifically, 4807 of these patients at 58 institutions were enrolled. Patients who exhibited lower serum albumin and higher serum C-reactive protein levels were defined as "malnourished" and "inflamed", respectively, compared with the median values. Patients who underwent invasive procedures for atherosclerotic diseases were defined as "atherosclerotic". The 36-month all-cause mortality rate in Japanese HD patients was 12.4%. This rate directly correlated with the number of MIA factors. The odds ratio of the all-cause mortality rate markedly and significantly increased as the number of factors increased. The presence of 3 MIA factors in HD patients was a significant predictor of mortality, as evidenced by a multivariate logistic regression analysis. This study clearly demonstrated the close association between MIA syndrome and high mortality in Japanese HD patients. Early detection and the adjustment of MIA factors are mandatory.

    Introduction In preparation for the London 2012 Olympic Games, existing syndromic surveillance systems operating in England were expanded to include daily general practitioner (GP) out-of-hours (OOH) contacts and emergency department (ED) attendances at sentinel sites (the GP OOH and ED syndromic surveillance systems: GPOOHS and EDSSS). Hypothesis/Problem The further development of syndromic surveillance systems in time for the London 2012 Olympic Games provided a unique opportunity to investigate the impact of a large mass-gathering event on public health and health services as monitored in near real-time by syndromic surveillance of GP OOH contacts and ED attendances. This can, in turn, aid the planning of future events. The EDSSS and GPOOHS data for London and England from July 13 to August 26, 2012, and a similar period in 2013, were divided into three distinct time periods: pre-Olympic period (July 13-26, 2012); Olympic period (July 27 to August 12); and post-Olympic period (August 13-26, 2012). Time series of selected syndromic indicators in 2012 and 2013 were plotted, compared, and risk assessed by members of the Real-time Syndromic Surveillance Team (ReSST) in Public Health England (PHE). Student's t test was used to test any identified changes in pattern of attendance. Very few differences were found between years or between the weeks which preceded and followed the Olympics. One significant exception was noted: a statistically significant increase (P value = .0003) in attendances for "chemicals, poisons, and overdoses, including alcohol" and "acute alcohol intoxication" were observed in London EDs coinciding with the timing of the Olympic opening ceremony (9:00 pm July 27, 2012 to 01:00 am July 28, 2012). Syndromic surveillance was able to provide near to real-time monitoring and could identify hourly changes in patterns of presentation during the London 2012 Olympic Games. Reassurance can be provided to planners of future mass-gathering events that there

The development of diabetes mellitus after renal transplant represents a major posttransplant complication that may adversely affect graft/patient survival. The aim of this study was to assess the role of metabolic syndrome in patients on hemodialysis as a risk factor for the incidence of new-onset diabetes mellitus after renal transplant.Patients and methods: This was a prospective observational epidemiologic study carried out in adult nondiabetic patients undergoing chronic hemodialysis and on the renal transplant waiting list between November 2008 and April 2009. Patients were followed up from Visit 1 (baseline to 6 months after the renal transplant. The analysis of the role of metabolic syndrome in hemodialysis patients as a risk factor for the incidence of new-onset diabetes mellitus after renal transplant included the estimation of relative risk and its 95% confidence interval (CI.Results: A total of 383 evaluable patients were entered into the study (mean age, 52.7 years; male, 57.7%; Caucasian, 90.1%. The prevalence of metabolic syndrome on hemodialysis was 30.4% (95% CI, 25.8%–35.4%. Hypertension was the most prevalent criterion for metabolic syndrome (65.0%, followed by low levels of high-density lipoprotein cholesterol (52.7%, abdominal obesity (36.2%, hypertriglyceridemia (32.4%, and impaired glucose (8.9%. After the renal transplant, the prevalence of metabolic syndrome was still 25.8%.

  6. Boerhaave syndrome - case report

    Directory of Open Access Journals (Sweden)

    Biljana Radovanovic Dinic

    Full Text Available ABSTRACT CONTEXT: Boerhaave syndrome consists of spontaneous longitudinal transmural rupture of the esophagus, usually in its distal part. It generally develops during or after persistent vomiting as a consequence of a sudden increase in intraluminal pressure in the esophagus. It is extremely rare in clinical practice. In 50% of the cases, it is manifested by Mackler's triad: vomiting, lower thoracic pain and subcutaneous emphysema. Hematemesis is an uncommon yet challenging presentation of Boerhaave's syndrome. Compared with ruptures of other parts of the digestive tract, spontaneous rupture is characterized by a higher mortality rate. CASE REPORT: This paper presents a 64-year-old female patient whose vomit was black four days before examination and became bloody on the day of the examination. Her symptoms included epigastric pain and suffocation. Physical examination showed hypotension, tachycardia, dyspnea and a swollen and painful abdomen. Auscultation showed lateral crackling sounds on inspiration. Ultrasound examination showed a distended stomach filled with fluid. Over 1000 ml of fresh blood was extracted by means of nasogastric suction. Esophagogastroduodenoscopy was discontinued immediately upon entering the proximal esophagus, where a large amount of fresh blood was observed. The patient was sent for emergency abdominal surgery, during which she died. An autopsy established a diagnosis of Boerhaave syndrome and ulceration in the duodenal bulb. CONCLUSION: Boerhaave syndrome should be considered in all cases with a combination of gastrointestinal symptoms (especially epigastric pain and vomiting and pulmonary signs and symptoms (especially suffocation.

    The role of longitudinal compressive failure mechanisms in notched cross-ply laminates is studied experimentally with in-situ synchrotron radiation based computed tomography. Carbon/epoxy specimens loaded monotonically in uniaxial compression exhibited a quasi-stable failure process, which was captured with computed tomography scans recorded continuously with a temporal resolutions of 2.4 seconds and a spatial resolution of 1.1 microns per voxel. A detailed chronology of the initiation and propagation of longitudinal matrix splitting cracks, in-plane and out-of-plane kink bands, shear-driven fiber failure, delamination, and transverse matrix cracks is provided with a focus on kink bands as the dominant failure mechanism. An automatic segmentation procedure is developed to identify the boundary surfaces of a kink band. The segmentation procedure enables 3-dimensional visualization of the kink band and conveys the orientation, inclination, and spatial variation of the kink band. The kink band inclination and length are examined using the segmented data revealing tunneling and spatial variations not apparent from studying the 2-dimensional section data.

    We aimed at investigating whether insulin resistance (IR)/sensitivity are impaired in obese/non-obese polycystic ovary syndrome (PCOS) and obese/non-obese healthy controls. A comprehensive literature search was performed for observational, English language studies. Meta-analysis was performed with the random effects model according to the heterogeneity. Eligible studies, involving 3037 women in four groups of: 1-obese, PCOS; 2-non-obese, PCOS, 3-obese, non-PCOS and 4-Non-obese, non-PCOS were included. Based on the insulin resistance index (HOMA-IR) analysis, the pooled mean (95% Conf. Interval) of HOMA IR in groups 1-4 were 4.38 (3.84, 4.92), 2.68 (2.16, 3.20), 2.44 (2.06, 2.82) and 1.34 (1.06, 1.63), respectively. Meta-analysis showed that group 1 (obese, PCOS patients) statistically have the highest IR and group 4 (non-obese, non-PCOS women) have the highest insulin sensitivity. Group 2 (non-obese, PCOS patients) and group 3 (obese, non-PCOS women) were between this range and they had lower IR than group 1 (obese, PCOS) and lower insulin sensitivity than group 4 (non-obese, non-PCOS). So, there were statistical differences between all groups except between groups 2 and 3. Insulin sensitivity indexes (quickie and ISI), also confirm the IR index (HOMA-IR) results. Based on different IR/sensitivity indexes, we found no evidence of any different effects of BMI ≥ 30 kg/m(2) on IR/sensitivity. In conclusion, PCOS status intensifies the adverse effects of obesity on IR, it has to be appropriately addressed in primary and secondary preventive cares and treatments provided for these women.

    The treatment of anemia in patients with cardiorenal syndrome (CRS) is based mainly on intravenous (IV) iron therapy and/or erythropoiesis-stimulating agents (ESAs). There are concerns about the safety of ESAs due to a potentially higher risk for stroke and malignancy. We aimed to explore whether IV iron alone is sufficient to improve anemia in CRS patients and to define the predictors of treatment response. We retrospectively analyzed data of 81 CRS patient treated for anemia at our clinic. All patients received IV iron for 6 weeks. A subset of patients was additionally given subcutaneous ESAs. The end point was the improvement from baseline in hemoglobin (Hb) and ferritin levels at week 7. We retrieved the files of 81 patients; 34 received IV iron alone and 47 were given IV iron and ESAs (the combination group). The Hb levels significantly increased in both groups (in the IV iron alone group: 10.6 ± 1.1 to 11.9 ±1.1 g/dl, p < 0.001; in the combination group: 10.2 ± 0.9 to 12.4 ± 1.3 g/dl, p < 0.001), but more pronouncedly in the combination group (2.17 vs. 1.24 g/dl; p = 0.001). The platelet count decreased significantly in the IV iron alone group but was unchanged in the combination group. Eighty percent of patients attained a Hb target of 11 g/dl, with no significant difference between the two groups (73.5 vs. 85.1%; p = 0.197). Low baseline Hb was the only predictor of a favorable outcome to treatment. Our observational study suggests that IV iron treatment without ESAs may substantially raise the Hb level to ≥11 g/dl in CRS patients. This treatment strategy may reduce the use of ESAs and hence its potential adverse effects.

    The ENVOL study was designed to assess the psychosocial impact of disease and therapy in a French cohort of cryopyrin-associated periodic syndromes (CAPS) patients (and caregivers) treated with canakinumab. The ENVOL study was a multicenter, observational study of CAPS patients given ≥1 canakinumab dose. Data were collected before treatment, at 6 and 12 months afterward, and at the last visit. Patients and caregivers completed questionnaires assessing changes from the 12 months of pretreatment to 12 months prior to interview. Data were analyzed retrospectively. The study included 10 physicians and 68 patients (53 adults, 15 children). Sixty-five patients (95.6%) were still receiving canakinumab at the last visit (median 5 years after starting therapy). The mean ± SD score for patient-reported general health increased from 7 ± 2.9 before canakinumab to 2.7 ± 2.7 after treatment (P 40% of respondents. Caregivers spent a median of 3 versus 0.5 hours/week on care in the 12 months of pretreatment versus 12 months prior to interview (P mean ± SD per patient per year: 5.2 ± 7.4 versus 8.5 ± 7.2 pretreatment), internists/rheumatologists/dermatologists (2.0 ± 2.1 versus 3.7 ± 3.9), and pediatricians (1.8 ± 1.5 versus 4.4 ± 4.2). Long-term treatment with canakinumab achieves a highly relevant improvement in the physical, emotional, and social lives of patients with CAPS, accompanied by a marked reduction in support required from caregivers and in health care consultations. © 2016, American College of Rheumatology.

    Women with polycystic ovary syndrome (PCOS) demonstrate an increased prevalence of cardiovascular disease (CVD) risk factors. Previous researchers have compared flow-mediated dilation (FMD), an early marker of CVD, in women with and without PCOS. Evidence for a PCOS-mediated reduction in FMD remains equivocal, potentially because of study differences in cohort-matching and measurement approaches. The aims of this systematic review and meta-analysis were to examine to what extent FMD is impaired in PCOS and to explore the influence of potential moderators of FMD reduction, such as age and BMI. A systematic review and meta-analysis of published observational studies comparing FMD in PCOS with control women. Twenty-one published studies were included (PCOS, n = 908; controls, n = 566). A subanalysis, using tighter inclusion criteria, involved seven studies (PCOS, n = 402; control, n = 251). Mean differences in FMD between PCOS and controls were synthesized. The subanalysis was delimited to the inclusion of age and BMI-matched controls. These factors were then explored as moderators using meta-regression. The pooled mean FMD was 3.4% (95% CI=1.9, 4.9) lower in PCOS compared with control women, with substantial heterogeneity between studies. In the subanalysis, the PCOS-mediated reduction in FMD was 4.1% (95% CI=2.7, 5.5). Heterogeneity remained substantial (I(2) =81%). Subsequent meta-regression indicated that the magnitude of FMD difference was not influenced by BMI (P = 0.17) nor age (P = 0.38). This systematic research synthesis indicates that endothelial function is compromised in PCOS women, even if they are young and nonobese. © 2012 Blackwell Publishing Ltd.

    Pneumonia is the leading risk factor of acute respiratory distress syndrome (ARDS). It is increasing studies in patients with pneumonia to reveal that coinfection with viral and bacterial infection can lead to poorer outcomes than no coinfection. This study evaluated the role of coinfection identified through bronchoalveolar lavage (BAL) examination on the outcomes of pneumonia-related ARDS. We performed a prospective observational study at Chang Gung Memorial Hospital from October 2012 to May 2015. Adult patients were included if they met the Berlin definition of ARDS. The indications for BAL were clinically suspected pneumonia-related ARDS and no definite microbial sample identified from tracheal aspirate or sputum. The presence of microbial pathogens and clinical outcomes were analyzed. Of the 19,936 patients screened, 902 (4.5%) fulfilled the Berlin definition of ARDS. Of these patients, 255 (22.7%) had pneumonia-related ARDS and were included for analysis. A total of 142 (55.7%) patients were identified to have a microbial pathogen through BAL and were classified into three groups: a virus-only group (n = 41 [28.9%]), no virus group (n = 60 [42.2%]), and coinfection group (n = 41 [28.9%]). ARDS severity did not differ significantly between the groups (P = 0.43). The hospital mortality rates were 53.7% in virus-only identified group, 63.3% in no virus identified group, and 80.5% in coinfection identified group. The coinfection group had significantly higher mortality than virus-only group (80.5% vs. 53.7%; P = 0.01). In patients with pneumonia-related ARDS, the BAL pathogen-positive patients had a trend of higher mortality rate than pathogen-negative patients. Coinfection with a virus and another pathogen was associated with increased hospital mortality in pneumonia-related ARDS patients.

    Since there is evidence that mental health aspects (such as depression) may inhibit an optimal rehabilitation outcome, there is growing interest in the psychosocial aspects of vision loss as part of rehabilitation. The purpose of this study is to provide more insight into the construct validity and (longitudinal) interpretation of goals related to 'Coping with mental (emotional) health aspects' which are part of the recently developed 'Dutch ICF Activity Inventory (D-AI). Moreover, the data allowed to provide some insight in the outcome in this domain in relation to rehabilitation programs followed in Dutch Multidisciplinary Rehabilitation Centers at baseline and follow-up. In a cohort of 241 visually impaired persons, the D-AI was assessed at baseline (enrollment), 4 and 12 months, The importance and difficulty of the D-AI goals 'Handle feelings', 'Acceptance', and 'Feeling fit' and difficulty scores of underlying tasks were further analyzed, together with similar or related standardized questionnaires. At baseline, Spearman correlations were determined between D-AI goals and task and additional questionnaires to investigate the construct validity. Corrected and uncorrected linear mixed models were used to determine longitudinal rehabilitation outcomes in relation to rehabilitation programs followed. Baseline correlations indicated that the difficulty of tasks and the umbrella goal 'Acceptance' were not similar. Longitudinal analyses provided insight in some subtle differences in concepts measured at the goal and task level of the D-AI, as well as similar validated questionnaires. After correcting for confounding variables, none of the underlying task difficulty scales changed over time. For goal difficulty scores only 'Acceptance' was reported to be significantly less difficult at 4 and 12 months follow-up. Importance scores of goals were stable from baseline to follow-up. With respect to the constructs measured, results support the formulation of the new goal

    Full Text Available PFAPA syndrome is the most common autoinflammatory disorder in childhood with unknown etiology. The aim of our study was clinical evaluation of PFAPA patients from a single tertiary care center and to determine whether variations of AIM2, MEFV, NLRP3, and MVK genes are involved in PFAPA pathogenesis. Clinical and laboratory data of consecutive patients with PFAPA syndrome followed up at the University Children’s Hospital, Ljubljana, were collected from 2008 to 2014. All four genes were PCR amplified and directly sequenced. Eighty-one patients fulfilled criteria for PFAPA syndrome, 50 (63% boys and 31 (37% girls, with mean age at disease onset of 2.1 ± 1.5 years. Adenitis, pharyngitis, and aphthae were present in 94%, 98%, and 56%, respectively. Family history of recurrent fevers in childhood was positive in 78%. Nineteen variants were found in 17/62 (27% patients, 4 different variants in NLRP3 gene in 13 patients, and 6 different variants in MEFV gene in 5 patients, and 2 patients had 2 different variants. No variants of clinical significance were found in MVK and AIM2 genes. Our data suggest that PFAPA could be the result of multiple low-penetrant variants in different genes in combination with epigenetic and environmental factors leading to uniform clinical picture.

    Myelodysplastic syndromes (MDS) and acute myeloid leukemia (AML) are myeloid neoplasms in which outgrowth of neoplastic clones disrupts normal hematopoiesis. Some patients with unexplained persistent cytopenias may not meet minimal diagnostic criteria for MDS but an alternate diagnosis is not apparent; the term idiopathic cytopenia of undetermined significance (ICUS) has been used to describe this state. MDS and AML occur primarily in older patients who are often treated outside the clinical trial setting. Consequently, our understanding of the patterns of diagnostic evaluation, management, and outcomes of these patients is limited. Furthermore, there are few natural history studies of ICUS. To better understand how patients who have MDS, ICUS, or AML are managed in the routine clinical setting, the Connect MDS/AML Disease Registry, a multicenter, prospective, observational cohort study of patients newly diagnosed with these conditions has been initiated. The Connect MDS/AML Disease Registry will capture diagnosis, risk assessment, treatment, and outcomes data for approximately 1500 newly diagnosed patients from approximately 150 community and academic sites in the United States in 4 cohorts: (1) lower-risk MDS (International Prognostic Scoring System [IPSS] low and intermediate-1 risk), with and without del(5q); (2) higher-risk MDS (IPSS intermediate-2 and high risk); (3) ICUS; and (4) AML in patients aged ≥ 55 years (excluding acute promyelocytic leukemia). Diagnosis will be confirmed by central review. Baseline patient characteristics, diagnostic patterns, treatment patterns, clinical outcomes, health economics outcomes, and patient-reported health-related quality of life will be entered into an electronic data capture system at enrollment and quarterly for 8 years. A tissue substudy to explore the relationship between karyotypes, molecular markers, and clinical outcomes will be conducted, and is optional for patients. The Connect MDS/AML Disease

    The objective of this study is to evaluate effectiveness of a firm's 5-year strategy toward improving well-being while lowering health care costs amidst adoption of a Consumer-Driven Health Plan. Repeated measures statistical models were employed to test and quantify association between key demographic factors, employment type, year, individual well-being, and outcomes of health care costs, obesity, smoking, absence, and performance. Average individual well-being trended upward by 13.5% over 5 years, monthly allowed amount health care costs declined 5.2% on average per person per year, and obesity and smoking rates declined by 4.8 and 9.7%, respectively, on average each year. The results show that individual well-being was significantly associated with each outcome and in the expected direction. The firm's strategy was successful in driving statistically significant, longitudinal well-being, biometric and productivity improvements, and health care cost reduction.

    Utilizing Add Health longitudinal data, we compared 21 male suicide casualties to 10,101 living respondents identifying suicide correlates. 21 suicide decedents completed surveys in 1994/1995 (Wave 1) and 11 completed at Wave 3; responses were compared with Chi-square and oneway ANOVA tests. Suicide decedents were prone to higher delinquency and fighting at Wave 1, but not at Wave 3. At Wave 1 suicide decedents remained undistinguished from living respondents in depression, self-esteem, and drug uses. Yet, after Wave 3, the 11 respondents dying by suicide showed significantly higher depression, drug use and lower self-esteem. Delinquency trends can readily understood, but more complex causes are needed to account for unexpected changes in self-esteem, depression and drug uses.

    The influence of social relationships on morbidity is widely accepted, but the size of the risk to cardiovascular health is unclear. We undertook a systematic review and meta-analysis to investigate the association between loneliness or social isolation and incident coronary heart disease (CHD) and stroke. Sixteen electronic databases were systematically searched for longitudinal studies set in high-income countries and published up until May 2015. Two independent reviewers screened studies for inclusion and extracted data. We assessed quality using a component approach and pooled data for analysis using random effects models. Of the 35 925 records retrieved, 23 papers met inclusion criteria for the narrative review. They reported data from 16 longitudinal datasets, for a total of 4628 CHD and 3002 stroke events recorded over follow-up periods ranging from 3 to 21 years. Reports of 11 CHD studies and 8 stroke studies provided data suitable for meta-analysis. Poor social relationships were associated with a 29% increase in risk of incident CHD (pooled relative risk: 1.29, 95% CI 1.04 to 1.59) and a 32% increase in risk of stroke (pooled relative risk: 1.32, 95% CI 1.04 to 1.68). Subgroup analyses did not identify any differences by gender. Our findings suggest that deficiencies in social relationships are associated with an increased risk of developing CHD and stroke. Future studies are needed to investigate whether interventions targeting loneliness and social isolation can help to prevent two of the leading causes of death and disability in high-income countries.

  5. Physical Activity, Sedentary Behavior, Cardiorespiratory Fitness and Metabolic Syndrome in Adolescents: Systematic Review and Meta-Analysis of Observational Evidence

    Science.gov (United States)

    2016-01-01

    Background Metabolic syndrome (MetS) has been diagnosed in adolescents and among the associated factors are low levels of physical activity, sedentary behavior over long periods and low cardiorespiratory fitness. However, specifically in adolescents, studies present conflicting results. The aim of the present study was to conduct a systematic review and meta-analysis of observational studies, in order to map the association between physical activity, sedentary behavior, cardiorespiratory fitness and MetS in adolescents. Methods A search was performed in the databases PubMed, SPORTDiscus, LILACS and the Cochrane Library. For the meta-analysis, the odds ratio (OR) was calculated together with the respective confidence intervals (95% CI), in which the measures of effect were analyzed by dichotomous data (exposure variables) with MetS used as events. Results Eighteen studies were included in the meta-analysis. Primary analysis demonstrated that low levels of physical activity (OR = 1.35 [1.03 to 1.79]; p = 0.03) and low cardiorespiratory fitness (OR = 4.05 [2.09 to 7.87]; p 2 hours/day, a significant association was not identified (OR = 1.20 [0.91 to 1.59]; p = 0.20). Subgroup analyses demonstrated that the association between low physical activity and MetS was dependent on the use of the accelerometry technique (OR = 2.93 [1.56 to 5.47]; p 2 hours/day was significantly associated with MetS only on weekends (OR = 2.05 [1.13 to 3.73]; p = 0.02). With respect to cardiorespiratory fitness, a significant association with MetS was found independent of the maximal oxygen uptake (VO2max) measurement method. Conclusions Low levels of physical activity, low indices of cardiorespiratory fitness and sedentary behavior, represented by screen time > 2 hours/day on weekends, were significantly associated with the development of MetS in adolescence.

    To determine factors associated with ambulance use in patients with confirmed and potential acute coronary syndrome presenting to the ED. A convenience sample of patients (n = 247) presenting to the ED from April 2014 to January 2015 with suspected acute coronary syndrome were included in the study. Data on mode of transport and patient demographics were collected from the Emergency Department Information System database. Clinical data were collected from chart records and information systems. A questionnaire assessed reasons for using a chosen method of transport, symptom timing and characteristics, acute coronary syndrome knowledge, and awareness of the National Heart Foundation Early Warning Symptoms campaign. Approximately half the patients (49.4%) assessed with symptoms of potential acute coronary syndrome used ambulance transport to the ED. Patients who arrived by ambulance were older than those not arriving by ambulance (mean 56.7 years vs 51.7 years, P = 0.01). Risk factors were not associated with ambulance use. Dizziness (P < 0.01), sweating (P = 0.03), nausea (P = 0.03) and vomiting (P = 0.04) were associated with increased ambulance use. Mean systolic blood pressure was lower in the ambulance group (136 mmHg, standard deviation [SD] = 19.8) than in the non-ambulance group (143 mmHg, SD = 25.9). Awareness of the National Heart Foundation Heart Attack Warning Signs campaign was not associated with ambulance use. Patients with possible ischaemic symptoms who are at a high risk of cardiac disease do not utilise ambulance services more than low risk patients. In general, transport to hospital using ambulance services by patients with symptoms of possible acute coronary syndrome is low despite community campaigns. © 2017 Australasian College for Emergency Medicine and Australasian Society for Emergency Medicine.

    Children affected by the 22q11.2 deletion syndrome (22q11.2DS) have a specific neuropsychological profile with strengths and weaknesses in several cognitive domains. Specifically, previous evidence has shown that patients with 22q11.2DS have more difficulties memorizing faces and visual-object characteristics of stimuli. In contrast, they have better performance in visuo-spatial memory tasks. The first focus of this study was to replicate these results in a larger sample of patients affected with 22q11.2DS and using a range of memory tasks. Moreover, we analyzed if the deficits were related to brain morphology in the structures typically underlying these abilities (ventral and dorsal visual streams). Finally, since the longitudinal development of visual memory is not clearly characterized in 22q11.2DS, we investigated its evolution from childhood to adolescence. Seventy-one patients with 22q11.2DS and 49 control individuals aged between 9 and 16 years completed the Benton Visual Retention Test (BVRT) and specific subtests assessing visual memory from the Children's Memory Scale (CMS). The BVRT was used to compute spatial and object memory errors. For the CMS, specific subtests were classified into ventral, dorsal, and mixed subtests. Longitudinal data were obtained from a subset of 26 patients and 22 control individuals. Cross-sectional results showed that patients with 22q11.2DS were impaired in all visual memory measures, with stronger deficits in visual-object memory and memory of faces, compared to visuo-spatial memory. No correlations between morphological brain impairments and visual memory were found in patients with 22q11.2DS. Longitudinal findings revealed that participants with 22q11.2DS made more object memory errors than spatial memory errors at baseline. This difference was no longer significant at follow-up. Individuals with 22q11.2DS have impairments in visual memory abilities, with more pronounced difficulties in memorizing faces and visual

    The clinical characteristics, initial presentation, management, and outcomes of patients hospitalized with new-onset (first diagnosis) heart failure (HF) or decompensation of chronic HF are poorly understood worldwide. REPORT-HF (International REgistry to assess medical Practice with lOngitudinal obseRvation for Treatment of Heart Failure) is a global, prospective, and observational study designed to characterize patient trajectories longitudinally during and following an index hospitalization for HF. Data collection for the registry will be conducted at ∼300 sites located in ∼40 countries. Comprehensive data including demographics, clinical presentation, co-morbidities, treatment patterns, quality of life, in-hospital and post-discharge outcomes, and health utilization and costs will be collected. Enrolment of ∼20 000 adult patients hospitalized with new-onset (first diagnosis) HF or decompensation of chronic HF over a 3-year period is planned with subsequent 3 years follow-up. The REPORT-HF registry will explore the clinical characteristics, management, and outcomes of HF worldwide. This global research programme may have implications for the formulation of public health policy and the design and conduct of international clinical trials. © 2015 The Authors.

    Full Text Available Trauma may result in craze lines on the enamel surface, one or more fractured cusps of posterior teeth, cracked tooth syndrome, splitting of posterior teeth, and vertical fracture of root. Out of these, management of some fractures is of great challenge and such teeth are generally recommended for extraction. Literature search reveals attempts to manage such fractures by full cast crown, orthodontic wires, and so forth, in which consideration was given to extracoronal splinting only. However, due to advancement in materials and technologies, intracoronal splinting can be achieved as well. In this case report, longitudinal fractures in tooth #27, tooth #37, and tooth #46 had occurred. In #27, fracture line was running mesiodistally involving the pulpal floor resulting in a split tooth. In teeth 37 and 46, fractures of the mesiobuccal cusp and mesiolingual cusp were observed, respectively. They were restored with cast gold inlay and full cast crown, respectively. Longitudinal fracture of 27 was treated with an innovative approach using intracanal reinforced composite with Ribbond, external reinforcement with an orthodontic band, and full cast metal crown to splint the split tooth.

    We examined the course of repetitive behavior and restricted interests (RBRI) in children with and without Down syndrome (DS) over a two-year time period. Forty-two typically-developing children and 43 persons with DS represented two mental age (MA) levels: "younger" 2-4 years; "older" 5-11 years. For typically developing younger children some aspects of RBRI increased from Time 1 to Time 2. In older children, these aspects remained stable or decreased over the two-year period. For participants with DS, RBRI remained stable or increased over time. Time 1 RBRI predicted Time 2 adaptive behavior (measured by the Vineland Scales) in typically developing children, whereas for participants with DS, Time 1 RBRI predicted poor adaptive outcome (Child Behavior Checklist) at Time 2. The results add to the body of literature examining the adaptive and maladaptive nature of repetitive behavior.

    Rapid economic and cultural transition in the United Arab Emirates has been accompanied by a rise in chronic disease. Early childhood is known to affect health outcomes in adulthood. This prospective longitudinal study examined the general health of Emirati infants born in a government maternity hospital in the Emirate of Abu Dhabi in October 2002. One hundred twenty-five women, who had recently given birth, were interviewed as part of a larger study encompassing a wide range of cultural, social, and behavioural aspects of health. They were then re-interviewed at three (n = 94), six (n = 59) and 15 months postpartum (n = 52). Data are presented using univariate statistics. In this study seven infants (6%) were born prematurely and four infants (3%) were classified as small for gestational age, while 11 (9%) of the infants weighed less than 2500 g. Low birth weight infants (LBW) were significantly more likely to require treatment in the neonatal intensive care unit (OR = 30.83, p = 0.00). Iron supplementation during pregnancy was associated with fewer underweight infants (OR = 3.92, p = 0.042). No associations were found between infant birth weight and maternal age, age at marriage, consanguinity, education level, current maternal employment, parity, pre-existing anaemia or anaemia in pregnancy, diabetes, folic acid intake, multivitamin intake or infant gender. Maternally-reported infant health issues, vaccination, medication, breast-feeding and infant nutrition, and use of secure car seats are also reported. The health of infants at birth in this UAE sample showed improvements compared to previous studies. The proportion of LBW infants is decreasing and continuing improvements in health care in the UAE are having a positive impact on infant health.

    Full Text Available Abstract Background The prevalence of obesity has increased in societies of all socio-cultural backgrounds. To date, guidelines set forward to prevent obesity have universally emphasized optimal levels of physical activity. However there are few empirical data to support the assertion that low levels of energy expenditure in activity is a causal factor in the current obesity epidemic are very limited. Methods/Design The Modeling the Epidemiologic Transition Study (METS is a cohort study designed to assess the association between physical activity levels and relative weight, weight gain and diabetes and cardiovascular disease risk in five population-based samples at different stages of economic development. Twenty-five hundred young adults, ages 25-45, were enrolled in the study; 500 from sites in Ghana, South Africa, Seychelles, Jamaica and the United States. At baseline, physical activity levels were assessed using accelerometry and a questionnaire in all participants and by doubly labeled water in a subsample of 75 per site. We assessed dietary intake using two separate 24-hour recalls, body composition using bioelectrical impedance analysis, and health history, social and economic indicators by questionnaire. Blood pressure was measured and blood samples collected for measurement of lipids, glucose, insulin and adipokines. Full examination including physical activity using accelerometry, anthropometric data and fasting glucose will take place at 12 and 24 months. The distribution of the main variables and the associations between physical activity, independent of energy intake, glucose metabolism and anthropometric measures will be assessed using cross-section and longitudinal analysis within and between sites. Discussion METS will provide insight on the relative contribution of physical activity and diet to excess weight, age-related weight gain and incident glucose impairment in five populations' samples of young adults at different stages

    The residential neighbourhood fast-food environment has the potential to lead to increased levels of obesity by providing opportunities for residents to consume energy-dense products. This longitudinal study aimed to examine whether change in body mass index (BMI) differed dependent on major chain fast-food outlet availability among women residing in disadvantaged neighbourhoods. Eighty disadvantaged neighbourhoods in Victoria, Australia. Sample of 882 women aged 18-46 years at baseline (wave I: 2007/2008) who remained at the same residential location at all three waves (wave II: 2010/2011; wave III: 2012/2013) of the Resilience for Eating and Activity Despite Inequality study. BMI based on self-reported height and weight at each wave. There was no evidence of an interaction between time and the number of major chain fast-food outlets within 2 (p=0.88), 3 (p=0.66) or 5 km (p=0.24) in the multilevel models of BMI. Furthermore, there was no evidence of an interaction between time and change in availability at any distance and BMI. Change in BMI was not found to differ by residential major chain fast-food outlet availability among Victorian women residing in disadvantaged neighbourhoods. It may be that exposure to fast-food outlets around other locations regularly visited influence change in BMI. Future research needs to consider what environments are the key sources for accessing and consuming fast food and how these relate to BMI and obesity risk. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    Despite injustice at the workplace being a potential source of sleep problems, longitudinal evidence remains scarce. We examined whether changes in perceived organizational justice predicted changes in insomnia symptoms. Data on 24 287 Finnish public sector employees (82% women), from three consecutive survey waves between 2000 and 2012, were treated as 'pseudo-trials'. Thus, the analysis of unfavourable changes in organizational justice included participants without insomnia symptoms in Waves 1 and 2, with high organizational justice in Wave 1 and high or low justice in Wave 2 (N = 6307). In the analyses of favourable changes in justice, participants had insomnia symptoms in Waves 1 and 2, low justice in Wave 1 and high or low justice in Wave 2 (N = 2903). In both analyses, the outcome was insomnia symptoms in Wave 3. We used generalized estimating equation models to analyse the data. After adjusting for social and health-related covariates in Wave 1, unfavourable changes in relational organizational justice (i.e. fairness of managerial behaviours) were associated with increased odds of developing insomnia symptoms [odds ratio = 1.15; 95% confidence interval (CI) 1.02-1.30]. A favourable change in relational organizational justice was associated with lower odds of persistent insomnia symptoms (odds ratio = 0.83; 95% CI 0.71-0.96). Changes in procedural justice (i.e. the fairness of decision-making procedures) were not associated with insomnia symptoms. These data suggest that changes in perceived relational justice may affect employees' sleep quality. Decreases in the fairness of managerial behaviours were linked to increases in insomnia symptoms, whereas rises in fairness were associated with reduced insomnia symptoms.

    Full Text Available Guillain-Barré syndrome is a rare acute polyradiculoneuropathy. Several variants and unusual presentations have been described, particularly in pediatrics. In most cases, making an early diagnosis is challenging due to the treatments that consist in the rapid administration of intravenous immunoglobulin or plasma exchange. The authors present the case of a 7-year-old boy with an atypical and severe axonal Guillain-Barré syndrome, associated with Mycoplasma pneumonia . When he was admitted, febrile respiratory failure was the main focus, and then he presented signs of acute polyneuropathy with cranial nerve palsy and brief hyperreflexia. Mechanical ventilation was required for 48 days as well as 2 cycles of intravenous immunoglobulin. The authors describe all the medical challenges that the authors encountered. This case highlights the fact that respiratory distress can be the main clinical symptom in children. This delays the establishment of a correct diagnosis, even more so when neurological manifestations are abundant and unusual.

    Mortensson, W.; Noack, G.; Curstedt, T.; Herin, P.; Robertson, B.

    Ten newborn babies with severe respiratory distress syndrome, all dependent on artificial ventilation, were treated via the airways with the isolated phospholipid fraction of bovine or porcine surfactant. After treatment with surfactant at a median age of 10.5 h, there was in all patients a striking improvement of lung aeration in chest films, with a decrease in parenchymal fluid retention and in distension of bronchioli. These radiologic findings were associated with a dramatic improvement of oxygenation and a significant reduction of the right-to-left shunt. In spite of the rapid therapeutic response, four patients died from cerebral hemorrhage. One of the surviving patients developed bronchopulmonary dysplasia. Our findings document efficacy of this new surfactant preparation in the neonatal respiratory distress syndrome, but the long-term effects need to be further tested in randomized clinical trials.

    This study aimed to investigate the associations between metabolic syndrome and type 2 diabetes and the presence of single nucleotide polymorphism of the vitamin D receptor gene in Iranian subjects with type 2 diabetes. Overall, 730 Iranian subjects (372 patients and 358 controls) were enrolled in this case-control study. Single nucleotide polymorphisms of the vitamin D receptor gene (FokI, BsmI, ApaI, and TaqI) were genotyped using the restriction fragment length polymorphism method. The statistical difference in genotype distribution among the groups was assessed by χ2 test. Logistic regression was performed to calculate odds ratios for the association of the genotype frequencies in different groups with the risk of metabolic syndrome and type 2 diabetes. The most common genotypes for BsmI, ApaI, TaqI, and FokI were Bb, Aa, TT, and FF, respectively. Adjusted χ2 test revealed that there was no difference between the groups in the genotypes frequencies of 4 vitamin D receptor polymorphisms in type 2 diabetes subjects. On the other hand, type 2 diabetes subjects with Tt genotype presented a signifi cantly higher fasting blood glucose than those with TT and tt genotypes in TaqI polymorphisms (p = 0.009). Logistic regression showed no association between metabolic syndrome risk and vitamin D receptor genotypes. We found no evidence for the association between vitamin D receptor gene polymorphisms and the risk for type 2 diabetes and metabolic syndrome in Iranian subjects. Further examinations using genome-wide association in large prospective cohort studies are warranted.

    Growth hormone (GH)/insulin-like growth factor 1 (IGF-1) axis abnormalities in multiple sclerosis (MS) suggest their role in its pathogenesis. Interferon β (IFN-β) efficacy could be mediated also by an increase of IGF-1 levels. A 2-year longitudinal study was performed to estimate the prevalence of GH and/or IGF-1 deficiency in clinically isolated syndrome (CIS) patients and their correlation with conversion to MS in IFN treated patients. Clinical and demographic features of CIS patients were collected before the start of IFN-β-1b. IGF-1 levels and GH response after arginine and GH releasing hormone + arginine stimulation tests were assessed. Clinical and magnetic resonance imaging evaluations were performed at baseline, 1 year and 2 years. Thirty CIS patients (24 female) were enrolled. At baseline, four patients (13%) showed a hypothalamic GH deficiency (GHD), whilst no one had a pituitary GHD. Baseline demographic, clinical and radiological data were not related to GHD, whilst IGF-1 levels were inversely related to age (P conversion occurrence. Growth hormone/IGF-1 axis function was found to be frequently altered in CIS patients, but this was not related to MS conversion. Patients experienced an improvement of GHD during IFN therapy. Longer follow-up is necessary to assess its impact on disease progression. © 2016 EAN.

    Non alcoholic fatty liver disease is an independent risk factor for coronary artery disease. But its effect on acute coronary syndrome is not clear. We performed this study to identify the prevalence of NAFLD in patients with ACS admitted to a tertiary care center in Sri Lanka. We also described the association of NAFLD with the severity of ACS predicted by the GRACE score. We performed a descriptive study including all consecutive patients with non-fatal ACS admitted to Colombo South Teaching Hospital from 01/02/2014 to 30/04/2014. Patients with excessive alcohol consumption, established cirrhosis and patients with identified risk factors for liver disease were excluded from the study. All patients underwent ultrasound scan of liver. There were 120 participants, 75 (62.5%) males and 45 (37.5%) females with acute coronary syndrome. Average age was 61.28 ± 11.83 years. NAFLD was seen in 56 (46.7%) patients with ACS. Patients with NAFLD had a higher GRACE score than patients without NAFLD (120.2 ± 26.9 Vs 92.3 ± 24.2, p acute coronary syndrome and thus require aggressive treatment of CAD. It is important to consider this novel risk factor when risk stratifying patients with ACS.

    Renal involvement is a severe complication in systemic lupus erythematosus (SLE). Moreover, a subset of SLE patients develop the anti-phospholipid syndrome (APS), characterised by the occurrence of anti-phospholipid antibodies in combination with macro- and microvascular thrombotic manifestations, including acute and chronic antiphospholipid-associated nephropathy (APLN). Clinical presentations of lupus nephritis and APLN are similar and a renal biopsy is necessary to differentiate between the conditions. Our aim with this study was to investigate the occurrence of histopathological findings consistent with APLN (hAPLN) in renal biopsies from SLE patients and to investigate associations with anti-phospholipid antibody specificities, clinical manifestations, HLA-DRB1 alleles, and long-term renal outcome. Consecutive renal biopsies from 112 SLE patients with renal involvement were investigated and evaluated for findings of hAPLN; in all there were 236 renal biopsies. Data from biopsy reports and clinical information were collected. Autoantibodies against cardiolipin and β2-glycoprotein-1 were measured by enzyme-linked immunosorbent assay. A lupus anticoagulant test was determined with a modified Dilute Russel Viper Venom method. HLA genotyping was performed by sequence-specific primer PCR. Renal outcome was determined at study end. The prevalence of hAPLN was 14.3% among SLE patients with renal involvement. Compared to patients with pure lupus nephritis, occurrence of hAPLN was associated with intima changes (odds ratio (OR) = 24; 95% confidence interval (CI), 3.0 to 189.8; P lupus nephritis patients (median 116 versus 75 μmol/L; P lupus nephritis. hAPLN is a severe and often unrecognized condition in SLE patients with renal involvement. We have demonstrated an increased risk for development of renal impairment and a genetic predisposition in hAPLN patients compared to lupus nephritis patients.

    To investigate changes of sick building syndrome (SBS) and different types of indoor exposures at home over an 8-year follow-up period (1989-1997), and onset of SBS symptoms in relation to size of residence town and education level. A random sample (0.1%) of the population in a 3-county region in Sweden, initially aged 20-65 years (n = 466). In total, 348 (75%) answered the postal follow-up questionnaire. Water leakage during the last year had decreased from 11.2 to 4.8% visible indoor mould had decreased from 4.7 to 1.6%, and any sign of building dampness decreased from 16.1 to 9.5%. The prevalence of current smoking had decreased from 30 to 19%. Smokers at baseline reported more onset of SBS symptoms than non-smokers. Furthermore, remission from mucosal symptoms was less likely in subjects that were tobacco smoker. Subjects with any indoor painting during follow-up period reported more onset of SBS symptoms, and those with intermediate education level had more onset of skin symptoms. Smoking and indoor painting could be predictors of new onset of SBS symptoms. Focus on indoor environment in Sweden the last decades may have resulted in environmental improvements in the dwellings, which can be beneficial both for the inhabitants and for the future public health.

    The presence of type 2 diabetes mellitus magnifies the risks associated with acute coronary syndrome (ACS), increasing the risk of recurrent cardiovascular events (CVEs) and doubling the risk of death. Managing cardiovascular risk factors has little effect on lowering the mortality risk in patients with type 2 diabetes. To evaluate the relationship between type 2 diabetes mellitus and subsequent CVEs and medication adherence following ACS hospitalization. Patients with ACS were identified using ICD-9-CM codes for acute myocardial infarction or unstable angina. The risk of subsequent CVEs was assessed at 1 and 3 years after the index ACS event based on type 2 diabetes status, adjusting for baseline demographic characteristics, comorbidities, medication use, and index ACS characteristics. Of 140,903 patients with ACS (mean age 66.8 years, 58.6% male), 27.4% had type 2 diabetes. During follow-up, 22.0% had subsequent CVEs (26.2% type 2 diabetes, 19.0% nondiabetes). After adjusting for other covariates, type 2 diabetes was associated with increased risk of subsequent CVEs by 9.7% at 1 year and 10.2% at 3 years (both P 2% type 2 diabetes, 77.5% nondiabetes). Patients with type 2 diabetes had statistically significant higher adherence rates for antiplatelet agents at 1 year and antihypertensives at 1 and 3 years versus nondiabetes patients. Persistence was higher in the type 2 diabetes group for antihypertensives and in the nondiabetes group for antiplatelet agents and statins. This analysis demonstrates that patients with type 2 diabetes have a higher risk of subsequent CVEs following an initial event versus those without diabetes, despite evidence of higher treatment persistence for certain medications. Adherence rates remained suboptimal, suggesting a continuing need for patient education.

    Coffee consumption has been postulated to decrease the risk of diabetes mellitus type II. The long-term effects of coffee consumption on the metabolic syndrome (MS) and its components are unknown. This study investigated the relationship of long-term coffee consumption between the age of 27 and 36 years with the prevalence of the MS at the age of 36 years. Data on coffee consumption and the MS components were derived from a healthy sample of 174 men and 194 women followed up from the age of 27 years onwards. Data analysis was performed with the use of generalized estimating equations and regression analysis. At the age of 36 years, the prevalence of the MS was 10.1%. The growth of coffee consumption did not differ significantly between subjects with or without the MS or its components. Regression analyses showed that one cup day(-1) higher coffee consumption was related to 0.11 mm Hg lower mean arterial blood pressure (P=0.03), 0.02 mg 100 ml(-1) higher triglyceride level (P=0.57), 0.04 mg 100 ml(-1) higher high-density lipoprotein cholesterol level (P=0.35), 0.09% higher HbA(1c) (P=0.12) and 0.02 cm larger waist circumference (P=0.57). After adjustment for physical activity, energy intake, smoking behaviour and alcohol consumption, none of the relationships between coffee consumption and the MS or its components was significant. Coffee consumption is not associated with the MS or its components in a healthy sample followed up for 9 years.

    To investigate whether karyotype, mid-childhood (6-10 years) follicle-stimulating hormone (FSH) and luteinizing hormone (LH) levels, and ultrasound ovary visualization results can be used as indicators of spontaneous puberty in Turner syndrome (TS). The analysis was based on clinical and biochemical data from 110 TS girls aged >13 years at the end of the study (1,140 visits between 1996 and 2015). The study population was divided according to karyotype: 45,X and non-45,X. The mean age ± standard deviation at diagnosis was 10.7 ± 4.0 years, and the follow-up duration was 5.9 ± 3.3 years. Spontaneous puberty was confirmed in 48% and menarche in 20% of the subjects, less frequently in 45,X girls. The mean age at Tanner stage B2 was 13.7 ± 2.4 years and that at menarche 14.2 ± 1.7 years, regardless of the karyotype. The median FSH level at 6-10 years was 8.16 IU/L, which was significantly lower than 10 years. The median LH level at 6-10 years was 0.35 IU/L, which was lower than >10 years. The chance of spontaneous menarche was decreased in girls with FSH ≥6.7 IU/L between 6 and 10 years. Although spontaneous puberty and menarche occur more frequently in non-45,X girls, the karyotype cannot be used to predict them. However, the chance of spontaneous menarche can be predicted based on gonadotropin cut-off values. There was no correlation between ultrasound ovary visualization results and spontaneous puberty. © 2017 S. Karger AG, Basel.

The aim was to study changes in maternal BC postpartum (PP to 1-year PP with reference to their prepregnancy body mass index (BMI status. Methods: The study design was a 1-year follow-up study. Sixty-five apparently healthy primiparous women (28.6 ± 3.4 years delivered full-term infants were randomly selected from December 2010 to June 2013 and postclassified on the basis of their prepregnancy BMI status. Anthropometry, sociodemographic status, physical activity, diet, clinical examination, biochemical tests, and BC at total body (dual energy X-ray absorptiometry, GE, Lunar DPX were collected using standardized protocols. Results: Forty-one women were classified in Group A with normal prepregnancy BMI (20.4 ± 2.0 kg/m2 and 24 women in Group B with overweight/obese (OW/OB prepregnancy BMI (26.1 ± 1.9 kg/m2. At 1 year, 75% of women returned to normal BMI in Group A, whereas all 100% of women from Group B remained in OW category at 1-year PP. Nearly 43% of Group B women showed the presence of at least two metabolic syndrome risk factors as compared to 36% in Group A at 1 year. Conclusion: Women with OW/OB prepregnancy BMI accumulated higher visceral fat with a higher prevalence of metabolic risk factors at 1-year PP. Our study underlines the importance of maintaining BMI status in reference range in reproductive years.

    Subcutaneous and submuscular anterior ulnar nerve transposition have been widely used in patients with cubital tunnel syndrome. However, the reliable evidence in favor of 1 of 2 surgical options on clinical improvement remains controversial. To maximize the value of the available literature, we performed a systematic review and meta-analysis to compare subcutaneous versus submuscular anterior ulnar nerve transposition in patients with ulnar neuropathy at the elbow. PubMed, Cochrane Library, and EMBASE databases were searched for randomized and observational studies that compared subcutaneous transposition with submuscular transposition of ulnar nerve for cubital tunnel syndrome. The primary outcome was clinically relevant improvement in function compared to the baseline. Randomized and observational studies were separately analyzed with relative risks (RRs) and 95% confidence intervals (CIs). Two randomized controlled trials (RCTs) and 7 observational studies, involving 605 patients, were included. Our meta-analysis suggested that no significant differences in the primary outcomes were observed between comparison groups, both in RCT (RR, 1.16; 95% CI 0.68-1.98; P = 0.60; I2= 81%) and observational studies (RR, 1.01; 95% CI 0.95-1.08; P = 0.69; I2 = 0%). These findings were also consistent with all subgroup analyses for observational studies. In the secondary outcomes, the incidence of adverse events was significantly lower in subcutaneous group than in submuscular group (RR, 0.54; 95% CI 0.33-0.87; P = 0.01; I2 = 0%), whereas subcutaneous transposition failed to reveal more superiority than submuscular transposition in static two-point discrimination (MD, 0.04; 95% CI -0.18-0.25; P = 0.74; I = 0%). The available evidence is not adequately powered to identify the best anterior ulnar nerve transposition technique for cubital tunnel syndrome on the basis of clinical outcomes, that is, suggests that subcutaneous and submuscular anterior transposition might be equally

    To compare the differences of therapeutic effect of chronic fatigue syndrome treated with the combined therapy of coiling dragon needling and cupping on back and the western medicine therapy with Prednisone. Seventy-two cases were randomly divided into an acupuncture and cupping group (37 cases) and a Prednisone group (35 cases). In acupuncture and cupping group, Jiaji (EX-B 2) points of T1--L5 were applied with coiling dragon needling (once a day), combined with moving cupping on back (once every two days); in Prednisone group, Prednisone tablets were orally taken for 10 mg at 8:00 am. Seven days made one course, and 2 courses were carried on totally. FS-14 scale and BELL's chronic fatigue syndrome integral table were applied to evaluate the fatigue degree of patients before and after treatment, and the therapeutic effects of both groups were compared. After one course of treatment, the BELL's scores of both groups were obviously improved (both P 0.05); after two courses of treatment, the BELL's score in acupuncture and cupping group improved more obviously than that in Prednisone group, and the total effective rate of 91.9% (34/37) in acupuncture and cupping group was superior to that of 71.4% (25/35) in Prednisone group (P cupping on back is positive, superior to that of Prednisone with oral administration.

    Two unpublished cases with partial tandem duplication of 12p and one previously published case were studied by fluorescence in situ hybridization using 11 cosmid DNA probes from 12p. We propose that the smallest duplications of 12(p13.2pter) and 12(p13.1p13.33) produce the {open_quotes}trisomy 12p syndrome{close_quotes} which is characterized by heavy birth weight, macrocephaly, muscular hypotonia, short neck, flat face, high forehead, prominent cheeks, large philtrum, short nose with anteverted nostrils, and broad everted lower lip. From a review of the published cases we conclude that gross malformations are lacking in {open_quotes}pure{close_quotes} trisomy 12p, and mental retardation is severe in complete and moderate in partial trisomy 12p. Polydactyly and accessory nipples were found only with almost complete trisomy 12p. Abnormalities of hair growth may be related to a gene at 12p. The sub-band 12p11.21 may be critical for acrocallosal syndrome. Macrocephaly may be due to a metabolic disorder. 26 refs., 5 figs., 3 tabs.

    Patients with poststroke complex regional pain syndrome (CRPS) show different symptoms compared to other types of CRPS, as they usually complain of shoulder and wrist pain with the elbow relatively spared. It is thus also known by the term "shoulder-hand syndrome."The aim of this study is to present a possible pathophysiology of poststroke CRPS through ultrasonographic observation of the affected wrist before and after steroid injection at the extensor digitorum communis (EDC) tendon in patients suspected with poststroke CRPS.Prospective evaluation and observation, the STROBE guideline checklist was used.Twenty-three patients diagnosed as poststroke CRPS in accordance to clinical criteria were enrolled. They had a Three Phase Bone Scan (TPBS) done and the cross-sectional area (CSA) of EDC tendon was measured by using ultrasonography. They were then injected with steroid at the EDC tendon. The CSA of EDC tendon, visual analogue scale (VAS), and degree of swelling of the wrist were followed up 1 week after the injection.TPBS was interpreted as normal for 4 patients, suspected CRPS for 10 patients, and CRPS for 9 patients. Ultrasonographic findings of the affected wrist included swelling of the EDC tendon. After the injection of steroid to the wrist, CSA and swelling of the affected wrist compared to that before the treatment was significantly decreased (P shoulder or rotator cuff tear of shoulder and soft tissue injury of the wrist caused by the hemiplegic nature of patients with stroke.

    We present a case of osteogenesis imperfecta (OI) type 2A in which a natural course in utero was observed from 23 weeks' gestation to term. At 23 weeks' gestation, a sonographic examination showed a cloverleaf skull-like head, a narrow thorax, and marked shortening of the long bones with bowing of the femurs and humeri. Follow-up examinations showed that the cloverleaf skull-like head was not evident at 28 weeks' gestation. Discontinuity of the ribs and femurs was observed at 26 and 30 weeks' gestation, respectively. This finding suggested bone fractures, which were confirmed by three-dimensional computed tomography at 32 weeks' gestation. Ultrasonographic findings of bones, including the long bones and calvarium, changed with advancing gestation during the second trimester. Characteristic features of OI type 2A were evident during the late second to early third trimesters. Repeated ultrasonographic examinations together with three-dimensional computed tomography are necessary for the definitive diagnosis of OI type 2A in the second trimester.

    Full Text Available Background. More than 50,000 cases of acute gastroenteritis are registered in children in Ukraine annually. Statistical data concerning rotavirus infection are not correct due to poor capacities of rotavirus laboratory diagnostics in medical units. The aim of the study was to estimate rotavirus infection burden, to analyze and describe rotavirus infection in children aged under 5 years old who were hospitalized into two infectious hospitals (Kyiv and Odessa within 2006–2015 period. Material and Methods. Investigation was carried according to a standard protocol, adopted by WHO. The disease severity was estimated by score scale for clinical manifestations of rotavirus gastroenteritis assessment of Vesikari. Results. At the period from December 2006 to December 2015 20,932 children aged under 5 years old were observed. Those children admitted to hospitals of infectious diseases in Kyiv and Odessa for acute gastroenteritis and met studies inclusive criteria. From them 18,384 (87.33 % children were investigated for rotavirus, i.e. wide majority of all children admitted to hospitals with gastroenteritis. The cause of their hospitalization was rotavirus infection in almost half of all children. It was mentioned that in some periods hospitalization rate for rotavirus as a cause of gastroenteritis was up to 70 % of all cases. In Ukraine incidence of rotavirus diarrhea in hospitalized children up to 5 years old was the highest one among 6 countries of the European region included into Global Rotavirus Surveillance Network. In Ukraine it was 41 % and the region mean value was 24 %. Within the total period of observation half of all hospitalizations caused by rotavirus occurred in children of first two years of life. All time the main viruses causing infection in both hospitals were of 4 genotypes: G1P[8], G2P[4], G3P[8], G4P[8]. Genotype G9P[8] possessed a significant position in Kyiv, but there were years, when it was not identified neither in Kyiv

    The aim was to study the prevalence, rate of appearance and severity of clinical features in patients with different anti-synthetase syndrome (ASyS) autoantibodies. All Johns Hopkins Myositis Longitudinal Cohort subjects positive for any ASyS autoantibodies were included. Clinical information, including symptoms, signs, strength, creatine kinase concentrations and pulmonary function tests, were prospectively collected. The standardized mortality and cancer rates and the rate of appearance and intensity of the different organ manifestations were assessed using univariate and multivariate analysis and compared between ASyS autoantibodies. One hundred and twenty-four (73.4%) patients were positive for anti-Jo1, 23 (13.6%) for anti-PL12, 16 for anti-PL7 (9.5%) and 3 (1.8%) for anti-EJ or anti-OJ, respectively. The mean length of follow-up was 4.1 years. Anti-PL12 was more frequent in black subjects. Anti-PL12 and anti-PL7 were associated with more prevalent and severe lung involvement, often without muscle involvement. Anti-Jo1 displayed more severe muscle involvement compared with anti-PL12 patients. Concurrent anti-Ro52 was more prevalent in anti-Jo1 patients and was associated with earlier development of mechanic's hands, DM-specific skin findings and arthritis. Independent of ASyS antibody status, black patients demonstrated more severe lung involvement than white patients. There was no significant increase in mortality or cancer risk in ASyS patients compared with the general US population. Different ASyS autoantibodies are associated with phenotypically distinct subgroups within the ASyS spectrum. Anti-PL7 and anti-PL12 are characterized by more severe lung involvement, whereas anti-Jo1 is associated with more severe muscle involvement. Black race is a major prognostic factor associated with lung disease severity.

    Guidelines recommend P2Y 12 inhibitor therapy for 1 year after myocardial infarction (MI), yet little guidance is provided on antiplatelet management for patients with recurrent ischemic events during that year. We describe changes in P2Y 12 inhibitor type among patients with recurrent ischemic events in the first year after MI. The TRANSLATE-ACS (Treatment With ADP Receptor Inhibitors: Longitudinal Assessment of Treatment Patterns and Events After Acute Coronary Syndrome) study enrolled 12 365 patients with MI treated with percutaneous coronary intervention. We examined whether P2Y 12 inhibitor choice changed among patients with recurrent MI, stent thrombosis, and/or unplanned revascularization during the first year after MI, and modeled factors associated with P2Y 12 inhibitor intensification (changing clopidogrel to prasugrel or ticagrelor). In the first year after MI, 1414 patients (11%) had a total of 1740 recurrent ischemic events (771 recurrent MIs, 969 unplanned revascularizations, and 165 stent thromboses). Median time to the first recurrent ischemic event was 154 days (25th-75th percentiles, 55-287 days). Of those with recurrent ischemic events, 101 of 1092 (9.3%) occurring in clopidogrel-treated patients led to P2Y 12 inhibitor intensification. Recurrent events involving stent thrombosis or MI were the strongest factors associated with P2Y 12 inhibitor intensification, yet only 40% of patients with stent thrombosis and 14% of patients with recurrent MI had P2Y 12 inhibitor intensification. Increasing age and longer time from the index MI were associated with lower likelihood for intensification. Few patients after MI with a recurrent ischemic event who were taking clopidogrel switched to a more potent P2Y 12 inhibitor, even after stent thrombosis events. Specific guidance is needed for patients who have recurrent ischemic events, particularly when closely spaced. URL: https://www.clinicaltrials.gov. Unique identifier: NCT01088503. © 2018 The Authors

    A growing number of studies are available to shed some light on the association between uric acid (UA) and cardiovascular diseases. However, there have been few studies to support a causal link between UA, metabolic syndrome (MetS), diabetes mellitus (DM) and hypertension (HTN) in young subjects. From the Health Examination Registration System of Taiwanese military service during the period 2013-2015, there were 46,561 eligible participants who were 20years old or older in our study. Different analytical steps of analysis were performed to examine the association between UA and cardiometabolic risk using logistic regression, receiver operating characteristic (ROC) curve analysis and Cox regression. For total population, serum UA had significant associations with the presence of MetS (OR=2.08, 95% CI=1.51-2.87), DM (OR=2.59, 95% CI=1.09-6.19) and HTN (OR=1.49, 95% CI=1.07-2.07) in the cross-sectional analysis. According to the cut-off values of UA calculating by the ROC curve analysis in each sex/age subgroup, the association between UA and incident adverse outcomes were analyzed in a longitudinal study. In male, higher UA significantly increased the risks for developing MetS in 30-40years (HR=1.12, 95% CI=1.01-1.25), DM in 40years (HR=2.99, 95% CI=1.34-6.64), HTN in >40years (HR=2.58, 95% CI=1.02-6.55), and no increased risk of DM. Our study concluded that serum UA is an important predictor for the risk of incident MetS, DM, and HTN in adults, especially in male population. Copyright © 2017. Published by Elsevier B.V.

    The aim of this study is to evaluate the risk of developing myofascial pain syndrome among patients diagnosed with insomnia. We conducted a population-based longitudinal study of a matched cohort with 7,895 participants (1,579 patients with insomnia and 6,316 controls) who were selected from the Taiwan National Health Insurance Research Database. The patients were observed for a maximum of 10 years to determine the incidence of newly diagnosed myofascial pain syndrome. A Cox regression analysis was performed to identify the risk factors associated with myofascial pain syndrome in patients with insomnia. During the 10-year follow-up period, 182 insomnia patients (14.9 per 1,000 person-years) and 379 controls (7.5 per 1,000 person-years) were diagnosed with myofascial pain syndrome. The incidence risk ratio of myofascial pain syndrome between the insomnia and control patients was 2.00 (95% confidence interval [CI] = 1.67-2.38, P  myofascial pain syndrome (95% CI = 1.62-2.31, P  myofascial pain syndrome in patients with insomnia. Patients with insomnia had a higher risk of developing myofascial pain syndrome than controls. This study adds to the understanding of the complex relationship between sleep disturbance and pain.

    Vertical groin incisions (VGIs) have been used to access femoral vessels, but reports allude to wound complications. Our aim was to compare VGI with transverse groin incision (TGI) for femoral artery exposure. Over a 5-year interval, 196 patients with 284 femoral artery exposures for supra- and infrainguinal procedures were studied. Primary endpoints were surgical skin site wound infection, seroma, haematoma formation, and major lower limb amputation. Secondary endpoints were graft patency, wound paresthesias, and length of hospital stay. There were 160 TGIs and 124 VGIs. The demographics and risk factor profile were not statistically different between groups. Seroma developed in 4.4% of TGIs and 13.7% of VGIs (p= .005). The complicated skin and soft tissue infection rate was five times greater with VGI (p= .001). The VGI group had a significantly higher rate of major amputation (p= .0005). Significantly higher graft failure rates were observed in the VGI group (p= .011). No paresthesia was reported in any TGI wound. The mean hospital stay was also significantly shorter in the TGI group (p= .006). The study data support and expound on the theory that an alternative incision to VGI offers lower short- and long-term morbidity. Our findings sustain the selection of the TGI in femoral artery surgery for both supra- and infrainguinal procedures without compromise of vessel exposure.

    Currently, no country-specific metastatic breast cancer (MBC) observational costing data are available for the Netherlands and Belgium. Our aim is to describe country-specific resource use and costs of human epidermal receptor 2 (HER-2)-positive MBC in the Netherlands and Belgium, making use of real-world data. The eligibility period for patient selection was from April 2004 to April 2010. Inclusion and retrospective data collection begins at the time of first diagnosis of HER-2-positive MBC during the eligibility period and ends 24 months post-index diagnosis of MBC or at patient death. We identified 88 eligible patients in the Netherlands and 44 patients in Belgium. The total costs of medical treatment and other resource use utilisation per patient was €48,301 in the Netherlands and €37,431 in Belgium. Majority of costs was related to the use of trastuzumab in both countries, which was 50% of the total costs in the Netherlands and 56% in Belgium respectively. Our study provides estimates of resource use and costs for HER-2-positive MBC in the Netherlands and Belgium. We noticed various differences in resource use patterns between both countries demonstrating caution is needed when transferring cost estimates between countries. © 2014 John Wiley & Sons Ltd.

    Full Text Available Abstract Background It is desirable that those at highest risk of cardiovascular disease should have priority for preventive measures, eg. treatment with prescription drugs to modify their risk. We wanted to investigate to what extent present use of cardiovascular medication (CVM correlates with cardiovascular risk estimated by three different risk scores (Framingham, SCORE and NORRISK ten years ago. Methods Prospective logitudinal observational study of 20 252 participants in The Hordaland Health Study born 1950-57, not using CVM in 1997-99. Prescription data obtained from The Norwegian Prescription Database in 2008. Results 26% of men and 22% of women aged 51-58 years had started to use some CVM during the previous decade. As a group, persons using CVM scored significantly higher on the risk algorithms Framingham, SCORE and NORRISK compared to those not treated. 16-20% of men and 20-22% of women with risk scores below the high-risk thresholds for the three risk scores were treated with CVM, while 60-65% of men and 25-45% of women with scores above the high-risk thresholds received no treatment. Among women using CVM, only 2.2% (NORRISK, 4.4% (SCORE and 14.5% (Framingham had risk scores above the high-risk values. Low education, poor self-reported general health, muscular pains, mental distress (in females only and a family history of premature cardiovascular disease correlated with use of CVM. Elevated blood pressure was the single factor most strongly predictive of CVM treatment. Conclusion Prescription of CVM to middle-aged individuals by large seems to occur independently of estimated total cardiovascular risk, and this applies especially to females.

    Full Text Available Background/Aims: Cardiorenal syndrome type 1 (CRS1 is a syndrome characterized by a rapid worsening of cardiac function leading to acute kidney injury (AKI. The aims of this study were to investigate the risk factors and the prognosis of CRS1 in elderly patients. Methods: A total of 312 elderly patients (≥60 years old with acute heart failure (AHF were studied. They were assigned as CRS1 (suffered from in-hospital AKI or NCRS1 (without AKI group. Clinical and laboratory data were recorded. Univariate and multivariate analysis were performed to clarify the risk factors for occurrence and mortality of CRS1 in this cohort. Results: Incidence of CRS1 was 52.56%. Basic estimated glomerular filtration (eGFR 2 and use of diuretics were associated with the higher risk of CRS1 in elderly patients (OR=2.239, P=0.025; OR=2.555, P=0.001; respectively. Whereas higher concentration of serum albumin was protective factor for them (OR=0.907, P=0.007. The in-hospital mortality of CRS1 was 23.2%. Dialysis, use of beta blockers or diuretics were associated with all-cause death of CRS1 patients (OR=10.407, PP=0.011; OR=0.345, P=0.040; respectively. The in-hospital mortality of AHF patients was 13.1%. Higher Charlson comorbidity index, occurrence of CRS1 and dialysis were risk factors for in-hospital mortality of AHF patients (OR=4.723, P=0.041; OR=6.096, P=0.008; OR=18.743, PConclusions: Incidence of CRS1 in elderly patients is relatively high and associated with poor outcome. Reduced basic eGFR, lower serum albumin and use of diuretics are risk factors for the occurrence of CRS1 in elderly patients, while use of diuretics, beta blockers and dialysis during hospitalization are predictors of in-hospital mortality in patients with CRS1. These results above suggest that more suitable treatments for the elderly with CRS1 might be needed.

    We compared two methods for osteoporotic vertebral fracture (VF) assessment on lateral spine radiographs, the Genant semiquantitative (GSQ) technique and a modified algorithm-based qualitative (mABQ) approach. We evaluated 4465 women and 1771 men aged ≥50 years from the Canadian Multicentre Osteoporosis Study with available X-ray images at baseline. Observer agreement was lowest for grade 1 VFs determined by GSQ. Among physician readers, agreement was greater for VFs diagnosed by mABQ (ranging from 0.62 [95% confidence interval (CI) 0.00-1.00] to 0.88 [0.76-1.00]) than by GSQ (ranging from 0.38 [0.17-0.60] to 0.69 [0.54-0.85]). GSQ VF prevalence (16.4% [95% CI 15.4-17.4]) and incidence (10.2/1000 person-years [9.2; 11.2]) were higher than with the mABQ method (prevalence 6.7% [6.1-7.4] and incidence 6.3/1000 person-years [5.5-7.1]). Women had more prevalent and incident VFs relative to men as defined by mABQ but not as defined by GSQ. Prevalent GSQ VFs were predominantly found in the mid-thoracic spine, whereas prevalent mABQ and incident VFs by both methods co-localized to the junction of the thoracic and lumbar spine. Prevalent mABQ VFs compared with GSQ VFs were more highly associated with reduced adjusted L 1 to L 4 bone mineral density (BMD) (-0.065 g/cm 2 [-0.087 to -0.042]), femoral neck BMD (-0.051 g/cm 2 [-0.065 to -0.036]), and total hip BMD (-0.059 g/cm 2 [-0.076 to -0.041]). Prevalent mABQ VFs compared with prevalent GSQ were also more highly associated with incident VF by GSQ (odds ratio [OR] = 3.3 [2.2-5.0]), incident VF by mABQ (9.0 [5.3-15.3]), and incident non-vertebral major osteoporotic fractures (1.9 [1.2-3.0]). Grade 1 mABQ VFs, but not grade 1 GSQ VFs, were associated with incident non-vertebral major osteoporotic fractures (OR = 3.0 [1.4-6.5]). We conclude that defining VF by mABQ is preferred to the use of GSQ for clinical assessments. © 2017 American Society for Bone and Mineral Research. © 2017 American Society for Bone

  12. Best Longitudinal Adjustment of Satellite Trajectories for the Observation of Forest Fires (Blastoff): A Stochastic Programming Approach to Satellite System Design

    Science.gov (United States)

    Hoskins, Aaron B.

    Forest fires cause a significant amount of damage and destruction each year. Optimally dispatching resources reduces the amount of damage a forest fire can cause. Models predict the fire spread to provide the data required to optimally dispatch resources. However, the models are only as accurate as the data used to build them. Satellites are one valuable tool in the collection of data for the forest fire models. Satellites provide data on the types of vegetation, the wind speed and direction, the soil moisture content, etc. The current operating paradigm is to passively collect data when possible. However, images from directly overhead provide better resolution and are easier to process. Maneuvering a constellation of satellites to fly directly over the forest fire provides higher quality data than is achieved with the current operating paradigm. Before launch, the location of the forest fire is unknown. Therefore, it is impossible to optimize the initial orbits for the satellites. Instead, the expected cost of maneuvering to observe the forest fire determines the optimal initial orbits. A two-stage stochastic programming approach is well suited for this class of problem where initial decisions are made with an uncertain future and then subsequent decisions are made once a scenario is realized. A repeat ground track orbit provides a non-maneuvering, natural solution providing a daily flyover of the forest fire. However, additional maneuvers provide a second daily flyover of the forest fire. The additional maneuvering comes at a significant cost in terms of additional fuel, but provides more data collection opportunities. After data are collected, ground stations receive the data for processing. Optimally selecting the ground station locations reduce the number of built ground stations and reduces the data fusion issues. However, the location of the forest fire alters the optimal ground station sites. A two-stage stochastic programming approach optimizes the

    Smoking has been shown to reduce health-related quality of life (HRQOL) in patients with coronary artery disease (CAD) undergoing percutanous coronary intervention (PCI) either by means of balloon angioplasty or with the use of bare-metal stents (BMS). Drug-eluting stents (DES) have now been widely used and are related to substantial reduction of restenosis and significantly improved HRQOL compared with BMS. This study aimed to evaluate the effects of smoking on HRQOL in patients after PCI in DES era. A cohort of 649 patients admitted for CAD and treated with drug-eluting stents were included in this prospective, observational study. Patients were classified as non-smokers (n = 351, 54.1%), quitters (n = 126, 19,4%), or persistent smokers (n = 172, 26.5%) according to their smoking status at the time they first admitted to hospital and during the first year of follow-up. Each patient was prospectively interviewed at baseline, 6 months and 1 year following PCI. HRQOL was assessed with the use of Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36). For the overall population, HRQOL scores at 1-year follow-up were significantly higher than baseline for all 8 domains. At 1-year follow-up, the HRQOL scores in persistent smokers were still lower than that in non-smokers in 6 domains except for bodily pain and mental health, and than that in quitters in 5 domains except for bodily pain, role emotional and mental health. There were no significant differences with regard to the scores between non-smokers and quitters except role emotional for which non-smokers had higher scores. After adjustment, persistent smokers demonstrated significantly less improvements in HRQOL than non-smokers in 6 domains except for bodily pain and social functioning and significantly less improvement than quitters for general health. Improvements of quitters were comparable to that of non-smokers in all domains. Multivariate linear regression analyses showed persistent

    Delays in diagnosis occur with complex regional pain syndrome (CRPS). We define and prospectively demonstrate that novel bedside tests measuring body perception disruption can identify patients with CRPS postfracture. The objectives of our study were to define and validate 4 bedside tests, to identify the prevalence of positive tests in patients with CRPS and other chronic pain conditions, and to assess the clinical utility (sensitivity, specificity, positive predictive value, negative predictive value) for identifying CRPS within a Fracture cohort. This was a single UK teaching hospital prospective cohort study with 313 recruits from pain-free volunteers and patients with chronic pain conditions.Four novel tests were Finger Perception (FP), Hand Laterality identification (HL), Astereognosis (AS), and Body Scheme (BS) report. Five questionnaires (Brief Pain Inventory, Upper Extremity Functional Index, Lower Extremity Functional Index, Neglect-like Symptom Questionnaire, Hospital Anxiety and Depression Score) assessed the multidimensional pain experience. FP and BS were the best performing tests. Prospective monitoring of fracture patients showed that out of 7 fracture patients (total n=47) who had both finger misperception and abnormal BS report at initial testing, 3 developed persistent pain with 1 having a formal diagnosis of CRPS. Novel signs are reliable, easy to perform, and present in chronic pain patients. FP and BS have significant clinical utility in predicting persistent pain in a fracture group thereby allowing targeted early intervention.

    A field investigation was conducted in the Sesheke District of Zambia along the Zambezi River to determine the fish species susceptible to epizootic ulcerative syndrome (EUS), a newly confirmed disease in Southern Africa. A total of 2,132 fishes were inspected for gross EUS-like lesions, of which 188 (8.82%; 95% CI=7.67-10.1%) were found with typical characteristic lesions of EUS. Of these 188 samples, 156 were found to have mycotic granulomas on histopathological analysis, representing 83.0% (95% CI=76.7-87.9%) of the initially identified in the laboratory through gross examination. The following 16 species of fish were examined and found with EUS lesions; Clarias ngamensis, Clarias gariepinus, Barbus poechii, Tilapia sparrmanii, Serranochromis angusticeps, Brycinus lateralis, Micralestes acutidens, Sargochromis carlottae, Hydrocynus vittatus, Phryngochromis acuticeps, Schilbe intermedius, Hepsetus odoe, Labeo lunatus, Oreochromis andersonii, Barbus unitaeniatus, and Barbus paludinosus. T. sparrmanii did not show any lesions, while the Clarias species were found to be the most afflicted with EUS. These results could be useful to fish farmers and organizations interested in improving aquaculture in the area.

  16. Protective and Predisposing Morphological Factors in Suprascapular Nerve Entrapment Syndrome: A Fundamental Review Based on Recent Observations

    Full Text Available Suprascapular nerve entrapment syndrome (SNES is a neuropathy caused by compression of the nerve along its course. The most common compression sites include the suprascapular notch and the spinoglenoid notch. The aim of this article was to review the anatomical factors influencing the occurrence of SNES in the light of the newest reports. Potential predisposing morphological factors include a V-shaped, narrow, or “deep” suprascapular notch; a band-shaped, bifurcated, or completely ossified superior transverse scapular ligament (STSL; particular arrangements of the suprascapular nerve and vessels at the suprascapular notch. A very recent report indicates structures at the suprascapular notch region that may protect from SNES, such as the suprascapular notch veins (SNV. The role of the anterior coracoscapular ligament (ACSL is still not clear. While some studies indicate that it may predispose for SNES, the newest study proposes a protective function. Knowledge of these variations is essential for arthroscopic and other surgical procedures of this area in order to avoid iatrogenic injury of the suprascapular nerve or unexpected bleeding from the suprascapular vessels running alongside the STSL.

    Renal replacement therapy (RRT) is a rescue therapy for patients with type 1 cardiorenal syndrome (CRS) with poor prognoses. However, the optimal timing for initiation and cessation of RRT remains controversial. The purpose of this study was to determine the optimal timing of initiation and cessation of RRT for patients with type 1 CRS. In this retrospective analysis, patients with refractory type 1 CRS receiving RRT were divided into 3 groups according to weaning from RRT and death within 90 days. Baseline characteristics, underlying heart disease, comorbidities, drug use before RRT, indicators of RRT initiation, and prognosis were compared between the 3 groups. Fifty-two patients were enrolled, which included 27 males and 25 females with a mean age of 70.7 ± 16.1 years and a 90-day mortality rate of 65.4%. The mean urine output before RRT initiation was 800 mL/ 24 h in the RRT-independent group, 650 mL/24 h in the RRT-dependent group, and 345 mL/ 24 h in the death group (p = 0.021). Additionally, there were obvious differences in fluid balance between the 3 groups (167, 250, and 1,270 mL, respectively, p = 0.016). Patients could be successfully weaned from RRT when urine output was >880 mL and fluid balance volume was 880 mL/24 h and volume balance is <150 mL/24 h.

    To compare the efficacy difference in the treatment of shoulder pain in post-stroke shoulder-hand syndrome among floating acupuncture, oral administration of western medicine and local fumigation of Chinese herbs. Ninety cases of post-stroke shoulder-hand syndrome (stage I) were randomized into a floating acupuncture group, a western medicine group and a local Chinese herbs fumigation group, 30 cases in each one. In the floating acupuncture group, two obvious tender points were detected on the shoulder and the site 80-100 mm inferior to each tender point was taken as the inserting point and stimulated with floating needling technique. In the western medicine group, mobic 7.5 mg was prescribed for oral administration. In the local Chinese herbs fumigation group, the formula for activating blood circulation and relaxing tendon was used for local fumigation. All the patients in three groups received rehabilitation training. The floating acupuncture, oral administration of western medicine, local Chinese herbs fumigation and rehabilitation training were given once a day respectively in corresponding group and the cases were observed for 1 month. The visual analogue scale (VAS) and Takagishi shoulder joint function assessment were adopted to evaluate the dynamic change of the patients with shoulder pain before and after treatment in three groups. The modified Barthel index was used to evaluate the dynamic change of daily life activity of the patients in three groups. With floating acupuncture, shoulder pain was relieved and the daily life activity was improved in the patients with post-stroke shoulder-hand syndrome, which was superior to the oral administration of western medicine and local Chinese herbs fumigation (P shoulder pain was superior to the oral administration of western medicine. The difference in the improvement of daily life activity was not significant statistically between the local Chinese herbs fumigation and oral administration of western medicine

    Extensive immunopathology occurs in human immunodeficiency virus (HIV)/tuberculosis (TB) coinfection, but the underlying molecular mechanisms are not well-defined. Excessive matrix metalloproteinase (MMP) activity is emerging as a key process but has not been systematically studied in HIV-associated TB. We performed a cross-sectional study of matrix turnover in HIV type 1 (HIV-1)-infected and -uninfected TB patients and controls, and a prospective cohort study of HIV-1-infected TB patients at risk of TB immune reconstitution inflammatory syndrome (TB-IRIS), in Cape Town, South Africa. Sputum and plasma MMP concentrations were quantified by Luminex, plasma procollagen III N-terminal propeptide (PIIINP) by enzyme-linked immunosorbent assay, and urinary lipoarabinomannan (LAM) by Alere Determine TB LAM assay. Peripheral blood mononuclear cells from healthy donors were cultured with Mycobacterium tuberculosis and extracellular matrix in a 3D model of TB granuloma formation. MMP activity differed between HIV-1-infected and -uninfected TB patients and corresponded with specific TB clinical phenotypes. HIV-1-infected TB patients had reduced pulmonary MMP concentrations, associated with reduced cavitation, but increased plasma PIIINP, compared to HIV-1-uninfected TB patients. Elevated extrapulmonary extracellular matrix turnover was associated with TB-IRIS, both before and during TB-IRIS onset. The predominant collagenase was MMP-8, which was likely neutrophil derived and M. tuberculosis-antigen driven. Mycobacterium tuberculosis-induced matrix degradation was suppressed by the MMP inhibitor doxycycline in vitro. MMP activity in TB differs by HIV-1 status and compartment, and releases matrix degradation products. Matrix turnover in HIV-1-infected patients is increased before and during TB-IRIS, informing novel diagnostic strategies. MMP inhibition is a potential host-directed therapy strategy for prevention and treatment of TB-IRIS.

    The association between obstructive sleep apnoea syndrome (OSAS), left ventricular (LV) diastolic dysfunction and LV geometry remains controversial because of coexisting disorders. To evaluate LV diastolic dysfunction and its independent predictors in a real-life cohort of OSAS patients, by a standardized approach. We consecutively included 188 OSAS patients after an overnight polysomnography to undergo clinical evaluation, ambulatory blood pressure measurement and complete echocardiography, combining M-mode, two-dimensional Doppler and tissue Doppler imaging modes. Correlations between OSAS severity and clinical and echocardiographical variables were assessed, and logistic regression models were used to identify possible determining factors of LV diastolic dysfunction. Most patients were hypertensive (n=148, 78.7%) and already receiving treatment by continuous positive airway pressure (n=158, 84.5%). The prevalence of LV hypertrophy, defined by LV mass index (LVMi) normalized by height (2.7), was 12.4%, with a significant correlation with hypertension (P=0.004). The apnoea-hypopnoea index was correlated with body mass index (P<0.0001), 24-hour systolic blood pressure (P=0.01) and LVMi normalized by height (2.7) (P=0.03). Diastolic function assessed by a global approach was impaired for 70 patients (37.2%) and none of the OSAS severity variables was a determining factor after multivariable analysis with adjustment for age and sex. Diastolic dysfunction assessed by a standardized approach is common in OSAS and should be routinely evaluated; it is independently predicted by none of the respiratory severity variables.

    Objective Despite the association of obesity with incident cardiovascular disease, obese patients with acute coronary syndrome (ACS) appear to have more favourable short-term outcomes. A study was undertaken to determine whether this ‘obesity paradox’ persists in the long term and to examine the specific relationship of central obesity with outcomes after ACS. Methods The relationship was investigated between two measures of obesity—body mass index (BMI) and waist circumference (WC)—and 30-day and 1-year outcomes after ACS. 6560 patients with non-ST elevation ACS in the MERLIN-TIMI 36 trial were followed for 1 year. Patients were stratified into three BMI groups (<25, 25–30, ≥30 kg/m2) and gender-specific tertiles of WC. The primary endpoint was cardiovascular death, myocardial infarction or recurrent ischaemia. Results Patients with BMI ≥30 kg/m2 had a significantly lower risk of the primary endpoint than those with BMI <25 kg/m2 (HR 0.64; 95% CI 0.51 to 0.81, p<0.0001) at 30 days. However, after the 30-day acute phase, landmark analysis from 30 days to 1 year showed no difference in risk between BMI groups (HR 1.09; 95% CI 0.92 to 1.29, p=0.34). WC tertiles demonstrated a similar relationship. When BMI groups were stratified by WC there was a trend towards more adverse outcomes in higher WC groups among those in lower BMI groups. The group with the lowest BMI and highest WC had the highest risk (HR 2.8; 95% CI 0.93 to 8.3; p=0.067). Conclusions Obesity is associated with more favourable short-term outcomes after ACS. However, in the longer term the obesity paradox is no longer present and may reverse. Those with WC out of proportion to BMI suggestive of significant central adiposity may be at highest risk following ACS. PMID:21865203

    Multiple case definitions are in use to identify chronic fatigue syndrome (CFS). Even when using the same definition, methods used to apply definitional criteria may affect results. The Centers for Disease Control and Prevention (CDC) conducted two population-based studies estimating CFS prevalence using the 1994 case definition; one relied on direct questions for criteria of fatigue, functional impairment and symptoms (1997 Wichita; Method 1), and the other used subscale score thresholds of standardized questionnaires for criteria (2004 Georgia; Method 2). Compared to previous reports the 2004 CFS prevalence estimate was higher, raising questions about whether changes in the method of operationalizing affected this and illness characteristics. The follow-up of the Georgia cohort allowed direct comparison of both methods of applying the 1994 case definition. Of 1961 participants (53 % of eligible) who completed the detailed telephone interview, 919 (47 %) were eligible for and 751 (81 %) underwent clinical evaluation including medical/psychiatric evaluations. Data from the 499 individuals with complete data and without exclusionary conditions was available for this analysis. A total of 86 participants were classified as CFS by one or both methods; 44 cases identified by both methods, 15 only identified by Method 1, and 27 only identified by Method 2 (Kappa 0.63; 95 % confidence interval [CI]: 0.53, 0.73 and concordance 91.59 %). The CFS group identified by both methods were more fatigued, had worse functioning, and more symptoms than those identified by only one method. Moderate to severe depression was noted in only one individual who was classified as CFS by both methods. When comparing the CFS groups identified by only one method, those only identified by Method 2 were either similar to or more severely affected in fatigue, function, and symptoms than those only identified by Method 1. The two methods demonstrated substantial concordance. While Method 2

    This was an observational study investigating the efficacy and side effects associated with ulipristal acetate (UPA), a progesterone receptor modulator, and the possible benefits to women who have co-existing pre-menstrual syndrome (PMS). 80 women returned a questionnaire on the bleeding, menstrual pain and side effects, and changes on PMS were recorded. 67 women (84%) showed improvement in their menses. 54 women (67%) became amenorrhoeic. Of those, 67% were within 10 days of commencing UPA. Menses returned in 33 amenorrhoeic women within 4 weeks of stopping UPA. 58 women (70%) reported an improvement in their pain score but 41 women had a return of their pain after stopping UPA. The majority of the women had no or infrequent side effects. 80% had demonstrable improvement in their PMS symptoms. UPA is effective in controlling symptoms due to uterine fibroids with infrequent side effects. Our data also showed new evidence of a concurrent dramatic improvement in PMS in these women. Impact statement The observational study explored the drug profile of ulipristal acetate (UPA), a selective progesterone receptor modulator, which has been licenced as pre-treatment for surgical therapies of fibroids since 2012. We aimed to investigate the efficiency and side effects of UPA. Since the introduction of UPA in clinical practice, there has yet to be a study looking at the drug profile outside a research setting. We have also decided to investigate the effect of UPA on pre-menstrual syndrome (PMS) in this group of women with symptomatic fibroids. As such this case report should be of interest to a broad readership including those interested in the medical management of symptomatic fibroids.

    Little is known about how clinicians use platelet function testing to guide choice and dosing of adenosine diphosphate receptor inhibitor (ADPri) therapy in routine community practice. The Treatment With Adenosine Diphosphate Receptor Inhibitors: Longitudinal Assessment of Treatment Patterns and Events After Acute Coronary Syndrome (ACS)-Prospective, Open Label, Antiplatelet Therapy Study (TRANSLATE-POPS) was a cluster-randomized trial in which 100 hospitals were assigned access to no-cost platelet function testing versus usual care for acute myocardial infarction patients treated with percutaneous coronary intervention. In both arms, ADPri treatment decisions were left up to the care team. The primary end point was the frequency of ADPri therapy adjustment before discharge. Secondary end points included 30-day rates of major adverse cardiovascular events and Global Utilization of Streptokinase and Tissue Plasminogen Activator for Occluded Coronary Arteries-defined bleeding events. Platelet function testing was performed in 66.9% of patients treated in intervention sites versus 1.4% of patients in usual care sites. Intervention arm patients were more likely to have ADPri therapy adjustment than usual care patients (14.8% versus 10.5%, P=0.004; odds ratio 1.68, 95% confidence interval 1.18-2.40); however, there were no significant differences in 30-day major adverse cardiovascular events (4.8% versus 5.4%, P=0.73; odds ratio 0.94, 95% confidence interval 0.66-1.34) or bleeding (4.3% versus 4.2%, P=0.33; odds ratio 0.86, 95% confidence interval 0.55-1.34). One-year outcomes were also not significantly different between groups. An as-treated analysis showed higher incidence of ADPri therapy adjustment among intervention arm patients who received platelet function testing than untested usual care arm (16.4% versus 10.2%, P<0.0001), but no significant differences in major adverse cardiovascular events or bleeding. TRANSLATE-POPS found that when clinicians routinely used

    Full Text Available Acquired immunodeficiency syndrome (AIDS is one of the main causes of death in adults worldwide. More commonly than in the general population, in patients with AIDS there is substantial disagreement between causes of death which are clinically suspected and those established by postmortem examination. The findings of 52 postmortem examinations were compared to the premortem (clinical diagnoses, and there was 46% agreement between them. Fifty two percent of the patients had more than one postmortem diagnosis, and 48% had at least one AIDS-related disease not suspected clinically. Cytomegalovirus infection was the commonest (30.7% autopsy finding, but not a single case had been suspected premortem. Bacterial infection, tuberculosis, and histoplasmosis were also common, sometimes not previously suspected, postmortem findings. This study shows that multiple infections occur simultaneously in AIDS patients, and that many among them are never suspected before the postmortem examination. These findings suggest that an aggressive investigation of infections and cancers should be done in patients with AIDS, particularly in those who do not respond to therapy of an already recognized conditionConcordância entre diagnósticos clínicos e de necrópsia em pacientes com síndrome da imunodeficiência adquirida observados em um hospital universitário brasileiro A síndrome da imunodeficiência adquirida (SIDA é uma das principais causas de morte em adultos em todo mundo.

    Trimethylaminuria (fish odor syndrome) is a metabolic disorder characterized by the inability to convert malodorous dietary-derived trimethylamine (TMA) to odorless TMA N-oxide by the flavin-containing monooxygenase 3 (FMO3). Mutations of the FMO3 gene were investigated in Japanese trimethylaminuria that showed low FMO3 metabolic capacity. Novel polymorphisms in the FMO3 gene causing stop codons at Cys197, Trp388, Gln470 or Arg500 of FMO3 were discovered in self-reported trimethylaminuria Japanese volunteers. Different metabolic capacities of FMO3 were observed for Asn114Ser, Thr201Lys, Arg205Cys or Met260Val FMO3 variants in addition to common Glu158Lys, Val257Met, and Glu308Gly FMO3. Estimated allelic frequencies for these novel mutated FMO3 genes for the Japanese population examined was approximately 1-4 % in this Japanese cohort. Recombinant Arg500stop (94% of the whole FMO3 structure) and several missense FMO3 variants showed no detectable activity and different effects on N- and S-oxygenation activities, respectively. The family members of Japanese probands who were heterozygous for these nonsense mutants generally showed moderate TMA N-oxygenation metabolic capacity, suggesting that heterozygotes for the nonsense mutations will exhibit trimethylaminuria symptoms only if they have, on the other chromosome, a mutation that substantially impairs enzyme activity. In addition, other causal factors for decreased FMO3 metabolic capacity such as liver damage or menstruation and treatment with copper chlorophyllin are also included in this minireview. The present article provides fundamental information for the importance of future investigations of the human FMO3 gene associated with trimethylaminuria (fish odor syndrome).

    Full Text Available Dengue is the most important mosquito-borne viral infection to affect humans. Although it usually manifests as a self-limited febrile illness, complications may occur as the fever subsides. A systemic vascular leak syndrome that sometimes progresses to life-threatening hypovolaemic shock is the most serious complication seen in children, typically accompanied by haemoconcentration and thrombocytopenia. Robust evidence on risk factors, especially features present early in the illness course, for progression to dengue shock syndrome (DSS is lacking. Moreover, the potential value of incorporating serial haematocrit and platelet measurements in prediction models has never been assessed.We analyzed data from a prospective observational study of Vietnamese children aged 5-15 years admitted with clinically suspected dengue to the Hospital for Tropical Diseases in Ho Chi Minh City between 2001 and 2009. The analysis population comprised all children with laboratory-confirmed dengue enrolled between days 1-4 of illness. Logistic regression was the main statistical model for all univariate and multivariable analyses. The prognostic value of daily haematocrit levels and platelet counts were assessed using graphs and separate regression models fitted on each day of illness. Among the 2301 children included in the analysis, 143 (6% progressed to DSS. Significant baseline risk factors for DSS included a history of vomiting, higher temperature, a palpable liver, and a lower platelet count. Prediction models that included serial daily platelet counts demonstrated better ability to discriminate patients who developed DSS from others, than models based on enrolment information only. However inclusion of daily haematocrit values did not improve prediction of DSS.Daily monitoring of platelet counts is important to help identify patients at high risk of DSS.

    Full Text Available Balint’s syndrome is a rare disorder affecting the ability to perceive the visual field as a whole, most commonly following damage to the bilateral occipital and parietal regions. This syndrome has three components as simultanagnosia, optic ataxia, and oculomotor apraxia. Simultanagnosia play a key role in this syndrome. Sixty-two years old male patient who applied the blindness symptom has been evaluated in outpatient clinic. We observed that there are some deficits in perceive of visual field rather than blindness in neurologic examination of the patient. He had simultanagnosia, optic ataxia and oculomotor apraxia. There are multiple infarcts in bilaterally occipital and parietal regions in the patient’s cerebral MRI. In this case, we have present a rare disorder of the Balint’s syndrome.

    Histopathologic studies have demonstrated WM damage in primary Sjögren syndrome. The purpose of this study was to evaluate WM microstructural changes by use of DTI-derived parameters in patients with primary Sjögren syndrome. DTI was performed in 19 patients with primary Sjögren syndrome (age, 64.73 ± 9.1 years; disease duration, 11.5 ± 7.56 years) and 16 age-matched control subjects. Exclusion criteria were a history of major metabolic, neurologic, or psychiatric disorder and high risk for cardiovascular disease. Data were analyzed by use of tract-based spatial statistics, for which the WM skeleton was created, and a permutation-based inference with 5000 permutations was used with a threshold of P primary Sjögren syndrome compared with control subjects, located mainly in the corticospinal tract, superior longitudinal fasciculus, anterior thalamic radiation, inferior fronto-occipital fasciculus, uncinate fasciculus, and inferior longitudinal fasciculus. Increased mean diffusivity and radial diffusivity and decreased axial diffusivity were observed in most of the fiber tracts of the brain in patients with primary Sjögren syndrome, compared with control subjects. Patients with primary Sjögren syndrome show loss of WM microstructural integrity, probably related to both Wallerian degeneration and demyelination.

    Before the early 1990s, parents were advised to place infants to sleep on their front contrary to evidence from clinical research. We systematically reviewed associations between infant sleeping positions and sudden infant death syndrome (SIDS), explored sources of heterogeneity, and compared findings with published recommendations. By 1970, there was a statistically significantly increased risk of SIDS for front sleeping compared with back (pooled odds ratio (OR) 2.93; 95% confidence interval (CI) 1.15, 7.47), and by 1986, for front compared with other positions (five studies, pooled OR 3.00; 1.69-5.31). The OR for front vs the back position was reduced as the prevalence of the front position in controls increased. The pooled OR for studies conducted before advice changed to avoid front sleeping was 2.95 (95% CI 1.69-5.15), and after was 6.91 (4.63-10.32). Sleeping on the front was recommended in books between 1943 and 1988 based on extrapolation from untested theory. Advice to put infants to sleep on the front for nearly a half century was contrary to evidence available from 1970 that this was likely to be harmful. Systematic review of preventable risk factors for SIDS from 1970 would have led to earlier recognition of the risks of sleeping on the front and might have prevented over 10 000 infant deaths in the UK and at least 50 000 in Europe, the USA, and Australasia. Attenuation of the observed harm with increased adoption of the front position probably reflects a "healthy adopter" phenomenon in that families at low risk of SIDS were more likely to adhere to prevailing health advice. This phenomenon is likely to be a general problem in the use of observational studies for assessing the safety of health promotion.

    The Ts65Dn mouse is partly trisomic at chromosome 16 and is considered to be a valid mouse model of human Down syndrome. Prior research using an incremental repeated acquisition (IRA) schedule of reinforcement has revealed that there is a significant learning deficit in young, adult Ts65Dn mice compared to littermate controls. The purpose of this study was to examine whether this deficit changes during the life-span of these mice. In order to determine if changes in the deficit were caused by motoric or motivational deficiencies, a second group of mice was trained to respond under a performance version of the task (IRA-P). The IRA-P task required the same motor responses to produce the reinforcer, but no learning or acquisition was required. Data collected under the IRA task demonstrated that there was a significant learning impairment that persisted up to 24 months of age in the Ts65Dn mice compared to littermate controls. There was a significant decrease in the rate of responding and the number of milk presentations earned by the Ts65Dn mice after 19 months of age. However, during this time, response accuracy, which is independent of mobility and possibly motivation, did not decrease. Under the IRA-P schedule, there was no decrease observed in the number of milk presentations of either line as they aged, but the trend in the rate of responding of the Ts65Dn mice was similarly declining as the rate of responding observed in the Ts65Dn mice under the IRA task. These data indicate that the ability to learn in Ts65Dn mice does not decline with age as measured by the IRA task and suggests that perhaps Ts65Dn mice do not exhibit the same early onset Alzheimer's disease phenotype that is typically seen in human patients.

    BACKGROUND Radiotherapy is explicitly indicated as one of the excluding factors in diagnosing overactive bladder syndrome (OAB). Nevertheless, symptoms of OAB such as urgent episodes, incontinence, pollakiuria, and nocturia, which are consequences of irradiation, led us to test the effectiveness of VESIcare®/Solifenacin in patients demonstrating these symptoms after radiation therapy of small pelvis organs due to malignant neoplasm. MATERIAL AND METHODS We conducted an observatory clinical study including 300 consecutive patients with symptoms of post-irradiation bladder; 271 of those patients completed the study. The observation time was 6 months and consisted of 3 consecutive visits taking place at 12-week intervals. We used VESIcare® at a dose of 5 mg a day. Every sixth patient was examined urodynamically at the beginning and at the end of the observation period, with an inflow speed of 50 ml/s. RESULTS We noticed improvement and decline in the average number of episodes a day in the following parameters: number of micturitions a day (-36%, P<0.01), nocturia (-50%, P<0.01), urgent episodes (-41%, P<0.03), and episodes of incontinence (-43%, P<0.01). The patients' quality of life improved. The average maximal cystometric volume increased by 34 ml (21%, p<0.01), average bladder volume of "first desire" increased by 42 ml (49%, P<0.01), and average detrusor muscle pressure at maximal cystometric volume diminished by 9 cmH2O (-36%, P<0.03). CONCLUSIONS The substance is well-tolerated. Solifenacin administered long-term to patients with symptoms of OAB after radiotherapy of a malignant neoplasm of the small pelvis organs has a daily impact in decreasing number of urgent episodes, incontinence, pollakiuria, and nocturia.

The primary aims of this study were to explore the differences between parental and clinical pain reporting in children with life-limiting conditions at the time of enrollment into an observational, longitudinal study and to determine if differences in pain experiences were associated with patient- or treatment-related factors. Pain was common, under-recognized and undertreated among the 270 children who enrolled into the “Charting the Territory” study. Children identified by their parents as experiencing pain (n=149, 55% were older, had more comorbidities such as dyspnea/feeding difficulties, were less mobile with lower functional skills and used analgesic medications more often, compared to pain-free children. Forty-one percent of children with parent-reported pain (21.8% of all patients experienced pain most of the time. The majority of clinicians (60% did not document pain assessment or analgesic treatment in the medical records of patients who were experiencing pain. Documentation of pain in the medical

Mixed effects models were used to assess cross-sectional and prospective associations of TT, SHBG and free testosterone (FT with MetS and its individual components. Multivariable adjusted odds ratios (ORs and hazard ratios (HRs were calculated and effect modification by age and BMI was studied.Men with low concentrations of TT, SHBG or FT were more likely to have prevalent MetS (ORs per quartile decrease were 1.69 (95% CI 1.60-1.77, 1.73 (95% CI 1.62-1.85 and 1.46 (95% CI 1.36-1.57 for TT, SHBG and FT, respectively and incident MetS (HRs per quartile decrease were 1.25 (95% CI 1.16-1.36, 1.44 (95% 1.30-1.60 and 1.14 (95% 1.01-1.28 for TT, SHBG and FT, respectively. Overall, the magnitude of associations was largest in non-overweight men and varied across individual components: stronger associations were observed with hypertriglyceridemia, abdominal obesity and hyperglycaemia and associations were weakest for hypertension.Associations of testosterone and SHBG with MetS vary according to BMI and individual MetS components. These findings provide further insights into the pathophysiological mechanisms linking low testosterone and SHBG concentrations to cardiometabolic risk.

  1. Longitudinal categorical data analysis

    2014-01-01

    This is the first book in longitudinal categorical data analysis with parametric correlation models developed based on dynamic relationships among repeated categorical responses. This book is a natural generalization of the longitudinal binary data analysis to the multinomial data setup with more than two categories. Thus, unlike the existing books on cross-sectional categorical data analysis using log linear models, this book uses multinomial probability models both in cross-sectional and longitudinal setups. A theoretical foundation is provided for the analysis of univariate multinomial responses, by developing models systematically for the cases with no covariates as well as categorical covariates, both in cross-sectional and longitudinal setups. In the longitudinal setup, both stationary and non-stationary covariates are considered. These models have also been extended to the bivariate multinomial setup along with suitable covariates. For the inferences, the book uses the generalized quasi-likelihood as w...

    The main soluble form of the receptor for advanced glycation end-products (sRAGE) is elevated during acute respiratory distress syndrome (ARDS). However other RAGE isoforms and multiple ligands have been poorly reported in the clinical setting, and their respective contribution to RAGE activation during ARDS remains unclear. Our goal was therefore to describe main RAGE isoforms and ligands levels during ARDS. 30 ARDS patients and 30 mechanically ventilated controls were prospectively included in this monocenter observational study. Arterial, superior vena cava and alveolar fluid levels of sRAGE, endogenous-secretory RAGE (esRAGE), high mobility group box-1 protein (HMGB1), S100A12 and advanced glycation end-products (AGEs) were measured in duplicate ELISA on day 0, day 3 and day 6. In patients with ARDS, baseline lung morphology was assessed with computed tomography. ARDS patients had higher arterial, central venous and alveolar levels of sRAGE, HMGB1 and S100A12, but lower levels of esRAGE and AGEs, than controls. Baseline arterial sRAGE, HMGB1 and S100A12 were correlated with nonfocal ARDS (AUC 0.79, 0.65 and 0.63, respectively). Baseline arterial sRAGE, esRAGE, S100A12 and AGEs were associated with severity as assessed by PaO2/FiO2. This is the first kinetics study of levels of RAGE main isoforms and ligands during ARDS. Elevated sRAGE, HMGB1 and S100A12, with decreased esRAGE and AGEs, were found to distinguish patients with ARDS from those without. Our findings should prompt future studies aimed at elucidating RAGE/HMGB1/S100A12 axis involvement in ARDS. clinicaltrials.gov Identifier: NCT01270295.

    Hypertension affects one billion people worldwide and is an independent risk factor for death after acute coronary syndrome (ACS). The aim of this study was to examine the prevalence and medical treatment of hypertension among 1,301 ACS patients enrolled into the Chinese registry of acute coronary events (CRACE) trial. Analyses were performed by gender, with both genders combined and according to international practice. Multivariable models identified factors associated with use of different classes of antihypertensive medication, and examined the correlation between hypertension and gender with mortality. The use of angiotensin‑converting enzyme inhibitors (ACEI), β-blockers, calcium channel blockers (CCBs) and diuretics increased in both genders during management of presenting ACS. Hypertensive men were more likely to have been receiving β-blockers when they were discharged (77.2%) than women (69.2%). Hypertensive women were more likely to have received diuretics when they were discharged (28.4%) than men (22%). ACEI use increased by ~60% (absolute increase) in both women and men as a result of ACS treatment, but remained similar between the genders, and the same phenomenon was observed in the use of CCBs. Moreover, hypertensive women were less likely to receive evidence‑based medication to treat their acute coronary event than men (for women and men, respectively: β-blocker, 69.2 vs. 77.2%; ACEI, 85.8 vs. 87.5%). Hypertension is more prevalent in women than in men with ACS, and its medical management varies with gender, but it has a similar association with mortality in both genders. Opportunities exist to improve medical therapy and outcomes for women with hypertension.

    Atherosclerotic heart diseases are less frequently seen in patients with Gilbert's syndrome (GS). We aimed to investigate whether serum adiponectin (APN) and epicardial adipose tissue (EAT) thickness have an effect beside the antioxidant effect of bilirubin in lowering the incidence of the atherosclerotic process. Sixty-eight patients diagnosed with GS (39 females and 29 males) who had applied at the internal medicine clinic of the hospital were included in this cross-sectional, observational study. The control group included 63 healthy people (39 females and 24 males). EAT thickness was measured by echocardiography. The serum APN levels were also checked. Statistical analysis was performed by using independent sample t-test, Pearson correlation and linear regression analyses. The mean age of the GS group was 28 ± 9 years, and the average EAT thickness was found to be 2.5 ± 0.1 mm. The mean age of the control group was 26 ± 6 years, and the average EAT thickness was found to be 4.2 ± 0.5 mm. When comparing the two groups, the EAT thickness of the GS group was found to be significantly lower (p<0.001) than that of the control group. In the GS group the APN was 14.9 ± 4.2 mg/L, and in the control group the APN was 12.6 ± 4.5 mg/L (p<0.022). We found that total bilirubin (β=-1,607, p<0,001) and indirect bilirubin (β=1,086, p<0,001) have an independent association with decreased EAT thickness. EAT thickness is associated with coronary atherosclerosis. Low EAT thickness may be related with low release of proinflammatory cytokine. High levels of APN may be related high anti-inflammatory effect. Therefore, low EAT thickness and high levels of APN may demonstrate protective effect on atherosclerotic heart diseases in GS patients.

    This paper examines the binary recurrent outcome "teenage smoking" within a statistical modelling paradigm. The proposed statistical modelling relates smoking to a set of explanatory variables, which include subjective as well as objective measures. In order to assess the degree to which explanatory variables influence smoking, an adequate statistical model must handle the possibility that substantial variation between respondents will be due to omitted variables, multicollinearity and past behaviour. An earlier paper, using a secondary cross-sectional data source, concluded that an investigation of smoking needs to be based on longitudinal data using appropriate statistical modelling. The same data source provided observations on young adults over a period of 2 years. For comparison purposes, the same cross-sectional model was fitted to the longitudinal data. The results suggest there may be substantial heterogeneity due to omitted variables in the data and complex inter-relationships between observed explanatory variables leading to underestimation. Longitudinal data provide additional flexibility to control for omitted variables and are necessary to investigate dynamic social processes such as smoking. The results from our analysis suggest that the effects of variables reported in the literature on teenage smoking may be overestimated. For example, the role of peer pressure may not be as clear as it has been made out to be.

    This article reports on 14 cases of a trichorhinophalangeal syndrome in five successive generations. Besides the well-known characteristics of the TRPS the following symptoms observed in this family are new: Teething was considerably delayed, intelligence was reduced, and there were skin manifestations resembling eczema. Besides, struma colli and colitis ulcerosa were also observed. Subsequent observations have to clarify whether these symptoms are a facultative part of the TRPS pattern. The constant appearance of carriers of these characteristics during five generation points to dominant heredity.

    Postinjection delirium/sedation syndrome (PDSS) has been reported uncommonly during treatment with olanzapine long-acting injection (LAI), a sustained-release formulation of olanzapine. The primary aim of the study was to estimate the incidence per injection and per patient of PDSS events in adult patients with schizophrenia who were receiving olanzapine LAI in real-world clinical practice. Secondary aims were to further characterise the clinical presentation of PDSS events, to identify potential risk factors associated with PDSS events and to characterise hospitalisations at baseline and post-baseline. A prospective observational study of adult patients with schizophrenia receiving olanzapine LAI from 24 countries. Data were collected on patient characteristics, olanzapine LAI treatment and any adverse events (AEs). All AEs were reviewed and adjudicated for PDSS using predetermined criteria. There were 46 confirmed PDSS events (0.044% of the 103 505 injections) in 45 patients (1.17% of the 3858 patients). Based on 45 confirmed events with time-to-onset information, 91.1% (n=41) occurred within 1 h of injection. Time-to-recovery from the event was within 72 h for 95.6% of patients (range 6 h to 11 days). Risk factors for PDSS (per-injection) included high dose (odds ratio (OR)high/low=3.95; P=0.006) and male gender (ORfemale/male=0.42; P=0.017). Results of this study confirm previously reported PDSS rates, time to onset and recovery, and the severity of PDSS events, and suggest that higher doses and male gender are potential risk factors associated with PDSS. All authors are full-time employees and hold stock/stock options in Eli Lilly, which funded this study.

  17. Longitudinal Magnification Drawing Mistake

    Rabal, Héctor; Cap, Nelly; Trivi, Marcelo

    2004-01-01

    Lateral magnification in image formation by positive lenses, mirrors, and dioptrics is usually appropriately developed in most optics textbooks.1-9 However, the image of a three-dimensional object occupies a three-dimensional region of space. The optical system affects both the transverse and the longitudinal dimensions of the object and, in general, does it in different ways. The magnification in the direction of the optical axis (the longitudinal magnification) is seldom treated. In several texts, the concept of longitudinal magnification is not even considered. Symmetrical objects (such as arrows) are used and their images appear laterally inverted. It is not shown how a longitudinally nonsymmetric object is imaged. One of the few books where this subject is well treated is in the textbook by Hecht.10 We have repeatedly verified in our classes that there is some confusion related to this subject. Students tend to believe that the image is longitudinally symmetric with respect to the lens optic center. Some prestigious texts commit the same mistake. In addition, a very nice optics book,11 a catalogue of optical hardware,12 a worldwide scientific magazine,13 a paper in an optics journal,14 and a Spanish encyclopedia,15 for example, have also been found to contain this error in drawing the image of a three-dimensional object formed by a positive lens. In this paper we suggest that the teaching of longitudinal magnification should be done with some care and we include a figure showing a properly drawn image.

    The Fibromialgia Syndrome (FS) is a common clinical entity which may produce symtoms and signs related to multiple fields of Medicine. Typical clinical characteristics of FS include extensive pain, presence of sensitive points during exploration, morning stiffness, asthenia and non-refresing sleep. Frequently, associated rheumatologic diseases are observed, as rheumatoid arthritis, osteoarthrosis and vertebral disorders. In FS, complementary tests are usually normal. The most widely accepted hypothesis suggests that this is a disorder affecting modulation of pain sensitivity.

    The traditional knowledge of local communities throughout the world is a valuable source of novel ideas and information to science. In this study, the ethnoveterinary knowledge of Sahrawi pastoralists of Western Sahara has been used in order to put forward a scientific hypothesis regarding the competitive interactions between camels and caterpillars in the Sahara ecosystem. Between 2005 and 2009, 44 semi-structured interviews were conducted with Sahrawi pastoralists in the territories administered by the Sahrawi Arab Democratic Republic, Western Sahara, using a snow-ball sampling design. Sahrawi pastoralists reported the existence of a caterpillar-borne reproductive loss syndrome, known locally as duda, affecting their camels. On the basis of Sahrawi knowledge about duda and of a thorough literature review, we built the hypothesis that: 1) caterpillars of the family Lasiocampidae (genera Lasiocampa, Psilogaster, or Streblote) have sudden and rare outbreaks on Acacia treetops in the Western Sahara ecosystem after heavy rainfall; 2) during these outbreaks, camels ingest the caterpillars while browsing; 3) as a consequence of this ingestion, pregnant camels have sudden abortions or give birth to weaklings. This hypothesis was supported by inductive reasoning built on circumstantiated evidence and analogical reasoning with similar syndromes reported in mares in the United States and Australia. The possible existence of a caterpillar-borne reproductive loss syndrome among camels has been reported for the first time, suggesting that such syndromes might be more widespread than what is currently known. Further research is warranted to validate the reported hypothesis. Finally, the importance of studying folk livestock diseases is reinforced in light of its usefulness in revealing as yet unknown biological phenomena that would deserve further investigation.

  1. Pendred syndrome.

    Pendred syndrome is an autosomal recessive disorder that is classically defined by the combination of sensorineural deafness/hearing impairment, goiter, and an abnormal organification of iodide with or without hypothyroidism. The hallmark of the syndrome is the impaired hearing, which is associated with inner ear malformations such as an enlarged vestibular aqueduct (EVA). The thyroid phenotype is variable and may be modified by the nutritional iodine intake. Pendred syndrome is caused by biallelic mutations in the SLC26A4/PDS gene, which encodes the multifunctional anion exchanger pendrin. Pendrin has affinity for chloride, iodide, and bicarbonate, among other anions. In the inner ear, pendrin functions as a chloride/bicarbonate exchanger that is essential for maintaining the composition and the potential of the endolymph. In the thyroid, pendrin is expressed at the apical membrane of thyroid cells facing the follicular lumen. Functional studies have demonstrated that pendrin can mediate iodide efflux in heterologous cells. This, together with the thyroid phenotype observed in humans (goiter, impaired iodine organification) suggests that pendrin could be involved in iodide efflux into the lumen, one of the steps required for thyroid hormone synthesis. Iodide efflux can, however, also occur in the absence of pendrin suggesting that other exchangers or channels are involved. It has been suggested that Anoctamin 1 (ANO1/TMEM16A), a calcium-activated anion channel, which is also expressed at the apical membrane of thyrocytes, could participate in mediating apical efflux. In the kidney, pendrin is involved in bicarbonate secretion and chloride reabsorption. While there is no renal phenotype under basal conditions, severe metabolic alkalosis has been reported in Pendred syndrome patients exposed to an increased alkali load. This review provides an overview on the clinical spectrum of Pendred syndrome, the functional data on pendrin with a focus on its potential role in

    Ethical issues and their optimal solutions in longitudinal infant studies have not received adequate attention in the literature. To address this gap, this manuscript pulls from universal research ethics, ethical guidelines for infant and child research, and ethical guidelines for longitudinal research and combines them in the context of infant longitudinal research with typically-developing infants. Topics explored relate to participant consent to research studies, the participant-observer relationship, and closure of developmental studies in this targeted population. Additionally, this manuscript highlights the importance and need for new and more relevant considerations of ethical procedures that concern infants involved in longitudinal research.

    Paraneoplastic syndromes (PNS) comprise a diverse group of disorders that are associated with cancer but unrelated to the size, location, metastases, or physiologic activities of the mature tissue of origin. They are remote effects of tumors that may appear as signs, symptoms, or syndromes which can mimic other disease conditions encountered in veterinary medicine. Recognition of PNS is valuable for several reasons: the observed abnormalities may represent tumor cell markers and facilitate early diagnosis of the tumor; they may allow assessment of premalignant states; they may aid in the search metastases; they may help quantify and monitor response to therapy; and, they may provide insight into the study of malignant transformation and oncogene expression. This review will concentrate on the pathophysiology, diagnosis, and treatment of some of the common PNS encountered in veterinary medicine.

This syndrome is related to the progressive impairment of health conditions and/or stressing events (ie, hospitalization, characterized by confusion and/or stupor, which are consequently difficult to manage and require a great deal of care. Geriatric patients often suffer from multiple chronic illnesses, may take numerous medications daily, exhibit clinical instability, and may experience worsening of medical conditions following cerebral ischemic events and thus have an increased risk of disability and mortality. There are several studies in literature which demonstrate the efficacy of citicoline, thanks to its neuroprotective function, for the recovery and in postischemic cerebral rehabilitation. It has been shown that, even soon after an ischemic stroke, administration of oral citicoline (500–4000 mg/day improves the general conditions evaluated with the Rankin scale and the National Institute of Health Stroke Scale 12. In particular, it has been shown that the CDP-choline improves the cognitive and mental performance in Alzheimer's dementia and vascular dementia. We have evaluated the administration of citicoline in geriatric patients following a protocol of intravenous study on improvement of individual performances.Keywords: geriatric syndrome, citicoline, Alzheimer's disease, cerebrovascular disease, comorbidities

    Gilles de la Tourette syndrome is a complex, idiopathic neuropsychiatric disorder whose pathophysiological mechanisms have yet to be elucidated. It is phenotypically heterogeneous and manifests more often than not with both motor and behavioral impairment, although tics are its clinical hallmark. Tics themselves present with a complex profile as they characteristically wax and wane and are often preceded by premonitory somatosensory sensations to which it is said a tic is the response. Highly comorbid with obsessive-compulsive disorder and attention deficit-hyperactivity disorder, it is purported to be an epigenetic, neurodevelopmental spectrum disorder with a complex genetic profile. It has a childhood onset, occurs disproportionately in males, and shows spontaneous symptomatic attenuation by adulthood in the majority of those afflicted. Although not fully understood, its neurobiological basis is linked to dysfunction in the cortico-basal ganglia-thalamo-cortical network. Treatment modalities for Tourette syndrome include behavioral, pharmacological and surgical interventions, but there is presently no cure for the disorder. For those severely affected, deep brain stimulation (DBS) has recently become a viable therapeutic option. A key factor to attaining optimal results from this surgery is target selection, a topic still under debate due to the complex clinical profile presented by GTS patients. Depending on its phenotypic expression and the most problematic aspect of the disorder for the individual, one of three brain regions is most commonly chosen for stimulation: the thalamus, globus pallidus, or nucleus accumbens. Neurophysiological analyses of intra- and post-operative human electrophysiological recordings from clinical DBS studies suggest a link between tic behavior and activity in both the thalamus and globus pallidus. In particular, chronic recordings from the thalamus have shown a correlation between symptomatology and (1) spectral activity in gamma

    Cockayne syndrome is a rare autosomal recessive disease. This paper reports a case of Cockayne syndrome confirmed by gene analysis. The baby (male, 7 years old) was referred to Peking University Third Hospital with recurrent desquamation, pigmentation and growth and development failure for 6 years, and recurrent dental caries and tooth loss for 2 years. Physical examination showed very low body weight, body length and head circumference, yellow hair, a lot of fawn spots on the face, skin dry and less elastic, and subcutaneous lipopenia. He had an unusual appearance with sunken eyes, sharp nose, sharp mandible, big auricle and dental caries and tooth loss. Crura spasticity and ataxia with excessive tendon reflexion, and ankle movement limitation while bending back were observed. He had slured speech. The level of serum insulin like growth factor I was low, and the results of blood and urinary amino acid analysis suggested malnutrition. The results of blood growth hormone, thyroxin, parathyroxin, liver function, renal function, lipoprotein profile and blood glucose and electrolytes were all within normal limit. An electronic hearing examination showed moderate neural hearing loss. The sonogram of eyes revealed small eye axis and vitreous body opacity of right side. MRI of brain revealed bilateral calcification of basal ganglia and generalized cerebral and cerebellar atrophy, and brainstem and callus were also atrophic. Genetic analysis confirmed with CSA gene mutation. So the boy was definitely diagnosed with Cockayne syndrome. He was discharged because of no effective treatment.

    To describe an atypical presentation of Susac syndrome. Observational case report. A 44-year-old man with no significant medical history presented with inferonasal visual field loss in his left eye of several months of duration. He was found to have bilateral migratory arteritis with focal areas of arteriolar occlusion in both eyes and peripheral ischemia superotemporally in his left eye. An extensive hematologic workup was negative for autoimmune disease or coagulopathy. Magnetic resonance imaging with contrast of his brain revealed a hyperintense lesion in the splenium of the corpus callosum. Auditory testing was significant for nonspecific high-frequency hearing loss in the right ear. Given the full clinical picture, a diagnosis of Susac syndrome was made. Susac syndrome is a multisystemic, immune-mediated occlusive endotheliopathy characterized by the clinical triad of encephalopathy, branch retinal artery occlusions, and hearing loss. However, patients may present with varying degrees of this triad; thus, there should be a high index of suspicion in patients presenting with multiple artery occlusions or multifocal arteritis.

    Metabolic Syndrome consists in a group of metabolic changes, being the most important problem insulin resistence. Other important components of this syndrome are abdominal obesity, hypertension and hyperlipidemia /hypercholestrolemia. It was demonstrated that psychiatric patients have a greater risk to develop metabolic syndrome with a prevalence of 41%. Prevalence of this syndrome in psychiatric male patients is 138% higher than in general population and in female patients 251% higher. Some of the factors that can explain this increase of metabolic risk in psychiatric patients are psychiatric drugs. We preformed a systematic review of literature published until June, 2007, by means of MEDLINE. Studies reviewed include clinical cases, reviews, analytic and observational studies. We selected 72 articles. Authors pretend to understand the mechanisms, by which, different psychiatric drugs can influence metabolic syndrome, and strategies for prevention of this situation.

    To compare the long-term effects of cardiopulmonary resuscitation (CPR) training and CPR/automatic external defibrillator (AED) training on anxiety and depression of patients who were medically stable after myocardial infarction (MI) and of their spouses/companions. Longitudinal. Post-MI patients (N=460) and their spouses/companions from the Home Automatic External Defibrillator Trial. Depression (Beck Depression Inventory-II scores) and anxiety (State Trait Anxiety Inventory scores). At study entry, 25% of the patients and 15% of their spouses were depressed and 21% of the patients and 19% of the spouses were anxious. The prevalence of depression and anxiety did not change over time in the patients or their spouses. Average depression and anxiety decreased for patients but not for spouses. An intervention group did not contribute significantly to these changes. Psychological distress, indicated by depression or anxiety of the spouse or the patient, occurred in 191 couples. Among psychologically distressed patients (N=128), depression and anxiety decreased over time; the intervention group did not contribute to these changes. The reduction in anxiety among male patients was greater than in female patients (p=0.012, 95% CI 0.002 to 0.018). Among psychologically distressed spouses (N=118), depression decreased over time independently of the intervention. Changes in spouse anxiety depended on the intervention group (p=0.012, 95% CI 0.001 to 0.012); anxiety decreased significantly in the CPR and remained high in the CPR/AED group. There was no evidence that home AEDs caused psychological distress among patients. Even among those who were psychologically distressed when they were assigned to receive either CPR training or CPR/AEDs, home AEDs did not influence changes in patients' depression or anxiety or spouses' depression in comparison with CPR training. Among psychologically distressed spouses, AEDs may keep anxiety higher than it would be otherwise. Interventions to

    The lesion of the lower four cranial nerves, commonly called Collet-Sicard syndrome, can be caused by a blunt head and neck trauma. It may be associated to an isolated fracture of the occipital condyle or of the atlas. The aim of this report is to assess the modality of the trauma, the type of fracture, the anatomic characteristics, the treatment and clinical results of this syndrome. We discuss 14 cases of fracture of occipital condyle and of atlas and 1 personal case. We analyzed 14 cases collected from the literature between 1925 and 2013, reported a further personal case and performed an anatomical study of the paracondylar, atlas and styloid process region. The anatomical dissection was performed to assess the anatomic relationships in the site of transit in which the nerves IX, X, XI and XII are injured. A total of 14 cases of p-CSS were collected: 9 caused by a condyle fracture and 5 by an atlas fracture. The patients were 13 males and only 1 female, 10 of them had a blunt trauma due to the result of axial loading (force directed through the top of the head and through the spine) falling on the head. The nine cases with a condyle fracture were associated to the dislocation of part of it, while those with atlas fractures showed the fracture and/or disjunction of the articular mass. The anatomical evaluations reveal that the lower four cranial nerves, at their emergency, pass through a close osteo-ligamentous space in relationship to the condyle. Below they run through a little wider channel between the articular mass of C1 and the styloid process. Two cases underwent surgical procedure. All the other cases were treated conservatively with immobilization of the cervical spine. During follow-up three cases with condylar fractures were found to be clinically unchanged and six showed modest improvements while one case with atlas fracture had a complete recovery and four improved significantly. The p-CSS is caused by force directed through the top of the head. We

    Le syndrome hémolytique et urémique (SHU) est une cause fréquente d'insuffisance rénale aiguë (IRA) organique chez l'enfant. C'est une complication évolutive des gastroentérites aiguës (GEA) en particulier à Escherichia coli de l'enfant. Notre objectif était de décrire les aspects cliniques, thérapeutiques et évolutifs de cette affection chez quatre enfants. Nous avions colligé quatre cas de SHU. L’âge moyen était de 10,5 mois (5-15mois) exclusivement des garçons. L'examen clinique retrouvait une anémie de type hémolytique (pâleur et ictére), un syndrome oedémateux avec oligo-anurie (2 cas), une hypertension artérielle (1 patient), une GEA avec déshydratation sévère et choc hypovolémique (2 patients), des troubles de conscience. L'IRA était notée chez tous les patients de même que la thrombopénie et les schizocytes au frottis. Le Coombs direct était négatif. Il y avait une hyperkaliémie (3patients) dont 1 patient supérieure à 9,2 mmol/l, une hyponatrémie à 129mmol/l(1 patient) et une hypernatrémie à 153mmol/l (1 patient). Le shu était secondaire à une pneumonie à pneumocoque (1 patient), une GEA à E. coli (1 patient). Le traitement était essentiellement symptomatique et comprenait la restriction hydrique, la transfusion de concentrés érythrocytaires, les diurétiques, la dialyse péritonéale et l'hémodialyse. L’évolution était marquée par la survenue d'une insuffisance rénale chronique (1 patient) après 6 mois de suivi et la guérison (1 cas). Nous avions noté 3décés. Le SHU est la cause la plus fréquente d'IRA organique du nourrisson. Le diagnostic est essentiellement biologique, le traitement est surtout symptomatique. PMID:27642476

    Full Text Available Abstract KBG syndrome is a rare condition characterised by a typical facial dysmorphism, macrodontia of the upper central incisors, skeletal (mainly costovertebral anomalies and developmental delay. To date, KBG syndrome has been reported in 45 patients. Clinical features observed in more than half of patients that may support the diagnosis are short stature, electroencephalogram (EEG anomalies (with or without seizures and abnormal hair implantation. Cutaneous syndactyly, webbed short neck, cryptorchidism, hearing loss, palatal defects, strabismus and congenital heart defects are less common findings. Autosomal dominant transmission has been observed in some families, and it is predominantly the mother, often showing a milder clinical picture, that transmits the disease. The diagnosis is currently based solely on clinical findings as the aetiology is unknown. The final diagnosis is generally achieved after the eruption of upper permanent central incisors at 7–8 years of age when the management of possible congenital anomalies should have been already planned. A full developmental assessment should be done at diagnosis and, if delays are noted, an infant stimulation program should be initiated. Subsequent management and follow-up should include an EEG, complete orthodontic evaluation, skeletal investigation with particular regard to spine curvatures and limb asymmetry, hearing testing and ophthalmologic assessment.

    There appears to be a close and probably causal relationship between early variations in phoneme skills and later reading skills in typically developing children, though the pattern in children with Down Syndrome is less clear. We present the results of a 2-year longitudinal study of 49 children with Down Syndrome (DS) and 61 typically developing…

    A 33-year-old male suffering from schizophrenia developed the typical symptoms of Cotard's syndrome, i.e., various delusions of negation and severe depressive symptoms. Atypical symptoms such as delusions of persecution and control related to body parts were also observed. These symptoms gradually improved by the treatment with sulpiride 300 mg/day. In the course of improvement of Cotard's syndrome, the patient developed Capgras syndrome. This report suggests that sulpiride is effective for Cotard's syndrome in schizophrenia. It also suggests that the symptoms of Cotard's syndrome are modified according to basic disorders, and this syndrome has a close connection with Capgras syndrome.

    Full Text Available Background: Neurocutaneous syndromes (NCS are a group of genetic disorders that produce a variety of developmental abnormalities of the skin along with an increased risk of neurological complications. Cutaneous manifestations usually appear early in life and progress with time, but neurological features generally present at a later age. There is a paucity of data regarding the evolution of skin lesions and their correlation with the central nervous system involvement in children. Aim: The primary objective was to track the course of skin lesions in various forms of NCS in the pediatric age group. Our secondary aim was to assess whether there was any predictive value of the lesions in relation to the neurological manifestations. Materials and Methods: This prospective longitudinal study was conducted at a tertiary care pediatric dermatology referral clinic of the Institute of Child Health, Kolkata, West Bengal. Children between the age group 0 and 12 years were included in the study on the basis of standard diagnostic criteria for different NCS, during the period from March, 2000 to February, 2004, and each of the enrolled cases were followed up for a duration of six years. Results: The study population comprised of 67 children (35 boys, 32 girls.The mean age of presentation was 33.8±27.8 months (range 10 days to 111 months. The various forms of NCS observed was neurofibromatosis 1(NF1 (n=33, tuberous sclerosis complex (TSC (n=23, Sturge Weber syndrome (n=6, ataxia telangiectasia (n=2, PHACE syndrome (n=1, incontinentia pigmenti (n=1, and hypomelanosis of Ito (n=1. The presentations were varied, ranging from predominantly cutaneous to primarily neurological, depending on the disease entity and age group concerned. There was a significant increase in the number of café au lait macules (CALMs with time (P=0.0002 in NF1, unlike that of hypopigmented macules of TSC (P=0.15. Statistically, no relation was documented between the evolution of skin

    Missing data are often problematic when analyzing complete longitudinal social network data. We review approaches for accommodating missing data when analyzing longitudinal network data with stochastic actor-based models. One common practice is to restrict analyses to participants observed at most or all time points, to achieve model convergence. We propose and evaluate an alternative, more inclusive approach to sub-setting and analyzing longitudinal network data, using data from a school friendship network observed at four waves (N =694). Compared to standard practices, our approach retained more information from partially observed participants, generated a more representative analytic sample, and led to less biased model estimates for this case study. The implications and potential applications for longitudinal network analysis are discussed.
