    Physiotherapy is an important part of rehabilitation following arthroplasty, but the impact of preoperative physiotherapy on functional outcomes is still being studied. This randomised controlled trial evaluated the effect of preoperative physiotherapy on the short-term functional outcomes of primary total knee arthroplasty (TKA). 50 patients with primary knee osteoarthritis who underwent unilateral primary TKA were randomised into two groups: the physiotherapy group (n = 24), whose patients performed physical exercises for six weeks immediately prior to surgery, and the nonphysiotherapy group (n = 26). All patients went through a similar physiotherapy regime in the postoperative rehabilitation period. Functional outcome assessment using the algofunctional Knee Injury and Osteoarthritis Outcome Score (KOOS) scale and range of motion (ROM) evaluation was performed preoperatively, and postoperatively at six weeks and three months. Both groups showed a significant difference in all algofunctional KOOS subscales (p 0.05). Significant differences were observed in the time-versus-treatment analysis between groups for the symptoms (p = 0.003) and activities of daily living (p = 0.025) subscales. No significant difference in ROM was found when comparing preoperative measurements and those at three months following surgery, as well as in time-versus-treatment analysis (p = 0.928). Six-week preoperative physiotherapy showed no significant impact on short-term functional outcomes (KOOS subscales) and ROM of the knee following primary TKA.

    Symptom severity and neuropsychological deficits negatively influence functional outcomes in patients with schizophrenia. Recent research implicates specific types of biased thinking styles (e.g. jumping-to-conclusions) in the pathogenesis of schizophrenia. This is the first study to test the impact of jumping-to-conclusions on functional outcome in schizophrenia. The aim of the study was to investigate the association of psychopathology, neuropsychology and JTC with subjective quality of life, vocational outcome and housing status in schizophrenia. Analyses were carried out both cross-sectionally at baseline, and longitudinally over the course of symptomatic improvement in the immediate aftermath of a psychotic exacerbation. Seventy-nine patients with schizophrenia were included in the study. Data concerning the variables of interest were collected at baseline, after one month, and after six months. Positive symptomatology was the most significant predictor of subjective and vocational outcome and changes across time. Verbal memory deficits were associated with functional status cross-sectionally, whereas general cognitive capacity significantly predicted functional changes over time. Improvement of the jumping-to-conclusions bias positively affected vocational outcome. Though limited, the observed effect of this bias on real-world functioning highlights the possible usefulness of interventions aimed at improving (meta)cognitive deficits in schizophrenia.

    Robotic rectal resection with da Vinci Si has some technical limitations, which could be overcome by the new da Vinci Xi. We compare short-term surgical and functional outcomes following robotic rectal resection with total mesorectal excision for cancer, with the da Vinci Xi (Xi-RobTME group) and the da Vinci Si (Si-RobTME group). The first consecutive 30 Xi-RobTME were compared with a Si-RobTME control group of 30 patients, selected using a one-to-one case-matched methodology from our prospectively collected Institutional database, comprising all cases performed between April 2010 and September 2016 by a single surgeon. Perioperative outcomes were compared. The impact of minimally invasive TME on autonomic function and quality of life was analyzed with specific questionnaires. The docking and overall operative time were shorter in the Xi-RobTME group (p  25 kg/m 2 was necessary in ten patients (45 vs. 0%, p da Vinci Xi seem to be mainly associated with a shorter docking and operative time and with superior ability to perform a fully-robotic approach. Clinical and functional outcomes seem not to be improved, with the introduction of the new Xi platform.

    In psychotic disorders, impairments in cognition have been associated with both clinical and functional outcome, while deficits in social cognition have been associated with functional outcome. As an extension to a recent report on neurocognition and short-term clinical outcome in first-episode psychosis (FEP), the current study explored whether social cognitive deficits could also identify poor short-term clinical outcome among FEP patients. We defined the social-cognition domain based on the scores from the Hinting Task and the Four Factor Tests of Social Intelligence. Data were collected in 45 FEP patients and 26 healthy controls. The patients were divided into good- and poor-outcome groups based on clinical data at six months following initiation of treatment. Social cognition was compared among 27 poor-outcome, 18 good-outcome, and 26 healthy-control participants. Outcome groups significantly differed in the social cognition domain (z-scores: poor outcome=-2.0 [SD=1.4]; good outcome=-1.0 [SD=1.0]; p=0.005), with both groups scoring significantly lower than the control group (psocial cognition appears to be compromised in all FEP patients compared to healthy controls. More interestingly, significant differences in social cognitive impairments exist between good and poor short-term clinical outcome groups, with the largest effect found in the Cartoon Predictions subtest.

    Full Text Available Abstract Background Exposure to cooking fumes may have different deleterious effects on the respiratory system. The aim of this study was to look at possible effects from inhalation of cooking fumes on pulmonary function. Methods Two groups of 12 healthy volunteers (A and B stayed in a model kitchen for two and four hours respectively, and were monitored with spirometry four times during twenty four hours, on one occasion without any exposure, and on another with exposure to controlled levels of cooking fumes. Results The change in spirometric values during the day with exposure to cooking fumes, were not statistically significantly different from the changes during the day without exposure, with the exception of forced expiratory time (FET. The change in FET from entering the kitchen until six hours later, was significantly prolonged between the exposed and the unexposed day with a 15.7% increase on the exposed day, compared to a 3.2% decrease during the unexposed day (p-value = 0.03. The same tendency could be seen for FET measurements done immediately after the exposure and on the next morning, but this was not statistically significant. Conclusion In our experimental setting, there seems to be minor short term spirometric effects, mainly affecting FET, from short term exposure to cooking fumes.

    To present our single-center experience with retroperitoneal laparoscopic partial nephrectomy (LPN) and retroperitoneal laparoscopic radical nephrectomy (LRN) for T1 renal hilar tumors and evaluate which one is better. A retrospective review of 63 patients with hilar tumors undergoing retroperitoneal LPN or LRN was performed. The perioperative characteristics, change in estimated glomerular filtration rate (eGFR) from baseline to month 3, and oncologic outcomes were summarized. In total, 25 patients underwent LPN, and 38 patients underwent LRN. The mean tumor size in the LPN and LRN groups was 4.5 and 4.9 cm, respectively. The mean operation time was longer in the LPN group than that in the LRN group (212.5 minutes versus 160.7 minutes, respectively; P  .05). In experienced hands, although retroperitoneal LRN can result in shorter operation times and shorter lengths of stay, retroperitoneal LPN can preserve renal function better than LRN. Retroperitoneal LPN should be the priority in selected patients with T1 renal hilar tumors, especially for patients with renal insufficiency.

The aim of the research is to examine the factors (age, IQ and reading skills that are expected the have an effect on short-term memory in children through regression analysis. One of the assumptions of regression analysis is to examine which has constant variance and normal distribution of the error term. In this study, because the error term is not normally distributed, robust regression techniques were applied. Also, for each technique; coefficient of determination is determined. According to the findings, the increase in age, IQ and reading skills caused the increase in short term memory in children. After applying robust regression techniques, the Winsorized Least Squares (WLS technique gives the highest coefficient of determination.

    Colostomy creation is a common procedure performed in colon and rectal surgery. Outcomes by technique have not been well studied. This study evaluated outcomes related to open versus laparoscopic colostomy creation. This was a retrospective review of patients undergoing colostomy creation using univariate and multivariate propensity score analyses. Hospitals participating in the American College of Surgeons National Surgical Quality Improvement Program database were included. Data on patients were obtained from the American College of Surgeons National Surgical Quality Improvement Program 2005-2011 Participant Use Data Files. We measured 30-day mortality, 30-day complications, and predictors of 30-day mortality. A total of 2179 subjects were in the open group and 1132 in the laparoscopic group. The open group had increased age (open, 64 years vs laparoscopic, 60 years), admission from facility (17.0% vs 14.9%), and disseminated cancer (26.1% vs 21.4%). All were statistically significant. The open group had a significantly higher percentage of emergency operations (24.9% vs 7.9%). Operative time was statistically different (81 vs 86 minutes). Thirty-day mortality was significantly higher in the open group (8.7% vs 3.5%), as was any 30-day complication (25.4% vs 17.0%). Propensity-matching analysis on elective patients only revealed that postoperative length of stay and rate of any wound complication were statistically higher in the open group. Multivariate analysis for mortality was performed on the full, elective, and propensity-matched cohorts; age >65 years and dependent functional status were associated with an increased risk of mortality in all of the models. This study has the potential for selection bias and limited generalizability. Colostomy creation at American College of Surgeons National Surgical Quality Improvement Program hospitals is more commonly performed open rather than laparoscopically. Patient age >65 years and dependent functional status are

    Vascular malformations (VM) are congenital lesions that can be debilitating and cause significant aesthetic and functional limitations. The chemotherapeutic agent bleomycin has been utilized as a sclerosant, directly injected percutaneously into the VM. Unfortunately, little is known about the benefits and short-term side effects of bleomycin with intralesional injections. An IRB approved, retrospective chart review was performed on patients with VM who had been treated with intralesional bleomycin. Data included type of VM, number of treatments, total bleomycin dose per m², and adverse effects. A questionnaire was administered to available patients to assess subjective outcomes and side effects. Forty-six patients were treated with 141 procedures of bleomycin sclerotherapy for VM. Patient ages ranged from 1 to 20 years (median age 10 years). The median cumulative bleomycin dose was 16.3 units/m²/person (range of 1.7-97.0 units/m²/person). Sixty-three percent of patients were reached for a questionnaire to assess short-term side effects. Ninety percent of patients surveyed were satisfied to very satisfied with the results from the procedure. About 24% of patients experienced transient nausea, vomiting and/or local hyperpigmentation. Bleomycin sclerotherapy can be an effective treatment of VM with repeat exposure with minor risk of short-term side effects, however, long-term risks are of great concern. Further studies are required to assess systemic absorption and long-term risks. © 2018 Wiley Periodicals, Inc.

    Cancer cachexia is an important measure of physiologic reserve associated with worse survival and represents an actionable factor for the cancer population. However, the incidence of cachexia in surgical cancer patients and its impact on postoperative outcomes are currently unknown. A prospective cohort study enrolling patients having elective cancer surgery (2012-2014) at a Veterans Affairs tertiary referral center. Preoperative cancer cachexia (weight loss ≥5% over 6-mo period before surgery) was the predictor of interest. The primary outcome was 60-d postoperative complications (VA Surgical Quality Improvement Program). Patients were grouped by body mass index (BMI) category (cachexia and BMI was tested for the primary outcome. Multivariate logistic regression was used to examine the association between preoperative cachexia and postoperative complications. Of 253 patients, 16.6% had preoperative cachexia, and 51.8% developed ≥ 1 postoperative complications. Complications were more common in cachectic patients (64.3% versus 49.3%, P = 0.07). This association varied by BMI category, and interaction analysis was significant for those with normal or underweight BMI (BMI cachexia was associated with higher odds of postoperative complications (odds ratios, 5.08 [95% confidence intervals, 1.18-21.88]; P = 0.029). Additional predictors of complications included major surgery (3.19 [1.24-8.21], P = 0.01), ostomy (4.43 [1.68-11.72], P = 0.003), and poor baseline performance status (2.31 [1.05-5.08], P = 0.03). Cancer cachexia is common in surgical patients, and is an important predictor of postoperative complications, though its effect varies by BMI. As a modifiable predictor of worse outcomes, future studies should examine the role of cachexia treatment before cancer surgery. Copyright © 2016 Elsevier Inc. All rights reserved.

    To determine the presentation and frequency of various intracranial neoplasms and assess outcomes for patients who underwent surgery without neuronavigation. This retrospective study was conducted at Combined Military Hospital, Peshawar, Pakistan, and comprised medical records related to the period from August 2011 to July 2014. Patient histories, examination reports and preoperative and post-operative radiological scans were reviewed and extent of excision was determined based on these coupled with recurrence rates. Intraoperatively, tumour excision was determined largely by the experience of the surgeon and preoperative planning using bony landmarks and radiological scans as an objective guide to resection. SPSS 21 was used for data analysis. Of the 143 patients, 83(57.9%) were males and 60(42.1%)were females. Gliomas were the most common tumours, occurring in 20(33.3%) females and 35(42.2%) males. One-year survival rate for grade 4 astrocytomas was poor (39.4%) and was excellent for meningiomas (100%) and pituitary tumours (100%). Time-tested methods of careful neurological examination and knowledge of neuroanatomy can allow a surgeon with limited resources to plan and accommodate for accurate tumour resection with adequate margins.

    2000-01-01

    Studies of family relationships in anorexia nervosa have produced conflicting results. Some authors claim that family factors are related to short-term outcomes. Perceived rearing practices, as measured by the EMBU (Egna Minnen Betraffande Uppfostran: 'My memories of Upbringing') were examined in a sample (N = 158) of adolescents with anorexia nervosa and compared with the perceptions of adolescents (N = 159) from the general population. A further comparison was made between the groups of patients with good and bad short-term outcomes. Logistic regression analysis was performed to evaluate the predictive value of different variables on short-term outcome. Overall, small differences were observed in the perceptions of rearing practices as expressed by the controls and the anorexic patients. Patients with bad short-term outcome perceived more rejection and control-overprotection from both parents than those with good outcome. In the logistic regression analysis only Rejection from father and the EAT (Eating Attitudes Test) total score gave independent prediction of treatment response. Taken as a whole, these results do not support the idea of altered rearing practices in anorexic patients, at least in young patients with a short evolution of the disease. Perceived rearing practices, especially 'rejection', appear to have an appreciable effect on the short-term outcome.

    The benefits, and variables influencing the benefits, of short-term dynamic psychotherapy for chronic major depression versus nonchronic major depression were examined for 49 patients. The two diagnostic groups started at the same level on the Beck Depression Inventory (BDI) and Global Assessment of Functioning Scale (GAF) and benefited similarly. The bases for the benefits were examined by linear models explaining 35% of termination BDI variance and 47% of termination GAF scores. By far the largest contributor to outcome was initial GAF, followed by presence of more than one comorbid Axis I diagnosis. Initial level of depression on the BDI was not a significant predictor of termination BDI. The chronic/ nonchronic distinction accounted for less than 1% of explained variance, and little was added by personality disorder, age, or gender. PMID:22700274

    Clinical spectrum, treatment and short-term outcomes were assessed among the 131 Rochester, Minnesota, men who contracted an initial hip fracture due to moderate trauma during 1978-89. Three-fourths of falls leading to hip fracture occurred indoors with little seasonality, and 91% of fractures were in men 65 years of age or older. The ratio of cervical to intertrochanteric femur fractures was 1.4:1, and there was a tendency toward more neurological conditions among the patients with cervical fractures. Hemiarthroplasty and total hip replacement were mostly performed for cervical fractures, while internal fixation was preferred for intertrochanteric fractures. In-hospital mortality was 11.5%, and the 30-day case fatality rate was 16.0%. Age and postoperative deterioration of mental status significantly increased the risk of early death, the latter even after adjustment in a multivariate model, while comorbidity had a suggestive but not statistically significant influence on mortality. More than half the men were discharged to nursing homes, and 79% of the patients who survived at 1 year resided in nursing homes or intermediate care facilities or were attended by home care. Only 41% of survivors recovered their prefracture level of functioning and nearly 60% of patients limped and required a cane or walker. After implementation of the prospective payment system in 1984, the length of hospital stay was reduced, but there was no change in early mortality rates, in the duration of physical therapy following fracture or in attendance at nursing homes. The results of this population-based study demonstrate the strong impact of hip fractures on short-term outcomes in men.

    Full Text Available To determine whether there is a significant association between maternal haemoglobin measured before delivery and short-term neonatal outcome in very preterm neonates.We included prospectively all live births occurring from 25 to 32+6 weeks of gestation in a tertiary care centre between January 1(st 2009 and December 31(st 2011. Outborn infants and infants presenting with lethal malformations were excluded. Three hundred and thirty-nine mothers and 409 infants met the inclusion criteria. For each mother-infant pair a prospective record of epidemiologic data was performed and maternal haemoglobin concentration recorded within 24 hours before delivery was retrospectively researched. Maternal haemoglobin was divided into quartiles with the second and the third one regarded as reference as they were composed of normal haemoglobin values. Short-term outcome was defined as poor in case of death during hospital stay and/or grades III/IV intraventricular haemorrhage and/or periventricular leukomalacia and/or necessity of ventriculoperitoneal shunt.The global rate of poor short-term neonatal outcome was 11.4% and was significantly associated with low maternal haemoglobin values. This association remained significant after adjustment for antenatal corticosteroids therapy, gestational age, parity, mechanism of preterm birth, mode of delivery and birth weight (aOR = 2.97 CI 95% [1.36-6.47]. There was no relation between short-term neonatal outcome and high maternal haemoglobin concentration values.We show that low maternal haemoglobin concentration at delivery is an independent risk factor for poor short-term neonatal outcome in very preterm neonates. This study is one of the first to show such an association within the preterm population.

    It is well established that the hyperdense middle cerebral artery sign is a specific marker for early ischemia in anterior circulation. However, little is known about the hyperdense basilar artery sign (HDBA) in posterior circulation. Our aim was to determine whether the HDBA sign has utility in early diagnosis of acute posterior circulation stroke and prediction of short-term outcome. Three-blinded readers examined unenhanced computed tomography scans for the HDBA sign, and materials were classified into two groups according to this sign. Vascular risk factors, admission and discharge National Institute of Health Stroke Scale (NIHSS) scores, short-term outcome, and radiological findings between the two groups were compared. One hundred and twenty-six cases of acute posterior circulation stroke (PCS) were included in the study. No statistically significant differences were found in risk factors of ischemic stroke, except atrial fibrillation (P = 0.025). Admission and discharge NIHSS scores for the positive HDBA group were significantly higher than scores for the negative HDBA group (P = 0.001, 0.002, respectively). The infarction territory for the positive HDBA group was mainly multi-region in nature (51.6%, P < 0.001), while the negative HDBA group showed mainly middle territory infarction. Significant independent predictors of short-term outcome included the HDBA sign (P < 0.001) and admission NIHSS scores (P < 0.001). Approximately half of the HDBA patients showed multi-region infarction and a serious neurological symptom. Based on our results, this sign might not only be helpful in early diagnosis of acute PCS but also be able to correlate with a poor short-term outcome. (orig.)

    Based on behavioral studies, several relatively distinct perceptual and cognitive functions have been defined in cognitive psychology such as sensory memory, short-term memory, and selective attention. Here, we review evidence suggesting that some of these functions may be supported by shared underlying neuronal mechanisms. Specifically, we present, based on an integrative review of the literature, a hypothetical model wherein short-term plasticity, in the form of transient center-excitatory and surround-inhibitory modulations, constitutes a generic processing principle that supports sensory memory, short-term memory, involuntary attention, selective attention, and perceptual learning. In our model, the size and complexity of receptive fields/level of abstraction of neural representations, as well as the length of temporal receptive windows, increases as one steps up the cortical hierarchy. Consequently, the type of input (bottom-up vs. top down) and the level of cortical hierarchy that the inputs target, determine whether short-term plasticity supports purely sensory vs. semantic short-term memory or attentional functions. Furthermore, we suggest that rather than discrete memory systems, there are continuums of memory representations from short-lived sensory ones to more abstract longer-duration representations, such as those tapped by behavioral studies of short-term memory.

    Cochlear implants (CIs) help many deaf children achieve near-normal speech and language (S/L) milestones. Nevertheless, high levels of unexplained variability in S/L outcomes are limiting factors in improving the effectiveness of CIs in deaf children. The objective of this study was to longitudinally assess the role of verbal short-term memory (STM) and working memory (WM) capacity as a progress-limiting source of variability in S/L outcomes after CI in children. Longitudinal study of 66 children with CIs for prelingual severe-to-profound hearing loss. Outcome measures included performance on digit span forward (DSF), digit span backward (DSB), and four conventional S/L measures that examined spoken-word recognition (Phonetically Balanced Kindergarten word test), receptive vocabulary (Peabody Picture Vocabulary Test ), sentence-recognition skills (Hearing in Noise Test), and receptive and expressive language functioning (Clinical Evaluation of Language Fundamentals Fourth Edition Core Language Score; CELF). Growth curves for DSF and DSB in the CI sample over time were comparable in slope, but consistently lagged in magnitude relative to norms for normal-hearing peers of the same age. For DSF and DSB, 50.5% and 44.0%, respectively, of the CI sample scored more than 1 SD below the normative mean for raw scores across all ages. The first (baseline) DSF score significantly predicted all endpoint scores for the four S/L measures, and DSF slope (growth) over time predicted CELF scores. DSF baseline and slope accounted for an additional 13 to 31% of variance in S/L scores after controlling for conventional predictor variables such as: chronological age at time of testing, age at time of implantation, communication mode (auditory-oral communication versus total communication), and maternal education. Only DSB baseline scores predicted endpoint language scores on Peabody Picture Vocabulary Test and CELF. DSB slopes were not significantly related to any endpoint S/L measures

    To determine if spinal cord diffusion tensor imaging indexes correlate with short-term clinical outcome in patients undergoing elective cervical spine surgery for cervical spondylotic myelopathy (CSM). A prospective consecutive cohort study was performed in patients undergoing elective cervical spine surgery for CSM. After obtaining informed consent, patients with CSM underwent preoperative T2-weighted magnetic resonance imaging and diffusion tensor imaging of the cervical spine. Fractional anisotropy (FA) values at the level of maximum cord compression and at the noncompressed C1-2 level were calculated on axial images. We recorded the modified Japanese Orthopaedic Association (mJOA) scale, Neck Disability Index, and Short Form-36 physical functioning subscale scores for all patients preoperatively and 3 months postoperatively. Statistical analysis was performed to identify correlations between FA and clinical outcome scores. The study included 27 patients (mean age 54.5 years ± 1.9, 12 men). The mean postoperative changes in mJOA scale, Neck Disability Index, and Short Form-36 physical functioning subscale scores were 0.9 ± 0.3, -6.0 ± 1.9, and 3.4 ± 1.9. The mean FA at the level of maximum compression was significantly lower than the mean FA at the C1-2 level (0.5 vs. 0.55, P = 0.01). FA was significantly correlated with change in mJOA scale score (Pearson r = -0.42, P = 0.02). FA was significantly correlated with the preoperative mJOA scale score (Pearson r = 0.65, P < 0.001). Preoperative FA at the level of maximum cord compression significantly correlates with the 3-month change in mJOA scale score among patients with CSM. FA was also significantly associated with preoperative mJOA scale score and is a potential biomarker for spinal cord dysfunction in CSM. Published by Elsevier Inc.

    Bronchopulmonary dysplasia (BPD) is a serious neonatal pulmonary condition associated with premature birth, but the underlying parenchymal disease and trajectory are poorly characterized. The current NICHD/NHLBI definition of BPD severity is based on degree of prematurity and extent of oxygen requirement. However, no clear link exists between initial diagnosis and clinical outcomes. We hypothesized that magnetic resonance imaging (MRI) of structural parenchymal abnormalities will correlate with NICHD-defined BPD disease severity and predict short-term respiratory outcomes. Forty-two neonates (20 severe BPD, 6 moderate, 7 mild, 9 non-BPD controls; 40±3 weeks post-menstrual age) underwent quiet-breathing structural pulmonary MRI (ultrashort echo-time and gradient echo) in a NICU-sited, neonatal-sized 1.5T scanner, without sedation or respiratory support unless already clinically prescribed. Disease severity was scored independently by two radiologists. Mean scores were compared to clinical severity and short-term respiratory outcomes. Outcomes were predicted using univariate and multivariable models including clinical data and scores. MRI scores significantly correlated with severities and predicted respiratory support at NICU discharge (P<0.0001). In multivariable models, MRI scores were by far the strongest predictor of respiratory support duration over clinical data, including birth weight and gestational age. Notably, NICHD severity level was not predictive of discharge support. Quiet-breathing neonatal pulmonary MRI can independently assess structural abnormalities of BPD, describe disease severity, and predict short-term outcomes more accurately than any individual standard clinical measure. Importantly, this non-ionizing technique can be implemented to phenotype disease and has potential to serially assess efficacy of individualized therapies.

    Full Text Available Introduction. Single-incision laparoscopic colectomy (SILC is a viable and safe technique; however, there are no single-institution studies comparing outcomes of SILC for colon cancer with well-established minimally invasive techniques. We evaluated the short-term outcomes following SILC for cancer compared to a group of well-established minimally invasive techniques. Methods. Fifty consecutive patients who underwent SILC for colon cancer were compared to a control group composed of 50 cases of minimally invasive colectomies performed with either conventional multiport or hand-assisted laparoscopic technique. The groups were paired based on the type of procedure. Demographics, intraoperative, and postoperative outcomes were assessed. Results. With the exception of BMI, demographics were similar between both groups. Most of the procedures were right colectomies ( and anterior resections (. There were no significant differences in operative time (127.9 versus 126.7 min, conversions (0 versus 1, complications (14% versus 8%, length of stay (4.5 versus 4.0 days, readmissions (2% versus 2%, and reoperations (2% versus 2%. Oncological outcomes were also similar between groups. Conclusions. SILC is an oncologically sound alternative for the management of colon cancer and results in similar short-term outcomes as compared with well-established minimally invasive techniques.

    Identification of pretreatment patient characteristics predictive of psychotherapy outcome could help to guide treatment choices. This study evaluates patients' initial level of immature defense style as a predictor of the outcome of short-term versus long-term psychotherapy. In the Helsinki Psychotherapy Study, 326 adult outpatients with mood or anxiety disorder were randomized to individual short-term (psychodynamic or solution-focused) or long-term (psychodynamic) psychotherapy. Their defense style was assessed at baseline using the 88-item Defense Style Questionnaire and classified as low or high around the median value of the respective score. Both specific (Beck Depression Inventory [BDI], Hamilton Depression Rating Scale [HDRS], Symptom Check List Anxiety Scale [SCL-90-Anx], Hamilton Anxiety Rating Scale [HARS]) and global (Symptom Check List Global Severity Index [SCL-90-GSI], Global Assessment of Functioning Scale [GAF]) psychiatric symptoms were measured at baseline and 3-7 times during a 3-year follow-up. Patients with high use of immature defense style experienced greater symptom reduction in long-term than in short-term psychotherapy by the end of the 3-year follow-up (50% vs. 34%). Patients with low use of immature defense style experienced faster symptom reduction in short-term than in long-term psychotherapy during the first year of follow-up (34% vs. 19%). Knowledge of patients' initial level of immature defense style may potentially be utilized in tailoring treatments. Further research on defense styles as outcome predictors in psychotherapies of different types is needed.

    2018-01-01

    Full Text Available Fluid-attenuated inversion recovery (FLAIR vascular hyperintensity (FVH is used to assess leptomeningeal collateral circulation, but clinical outcomes of patients with FVH can be very different. The aim of the present study was to assess a FVH score and explore its relationship with clinical outcomes. Patients with acute ischemic stroke due to middle cerebral artery M1 occlusion underwent magnetic resonance imaging and were followed up at 10 days (National Institutes of Health Stroke Scale and 90 days (modified Rankin Scale to determine short-term clinical outcomes. Effective collateral circulation indirectly improved recovery of neurological function and short-term clinical outcome by extending the size of the pial penumbra and reducing infarct lesions. FVH score showed no correlation with 90-day functional clinical outcome and was not sufficient as an independent predictor of short-term clinical outcome.

  10. Neuromuscular function and fatigue resistance of the plantar flexors following short-term cycling endurance training

    2015-05-01

    Full Text Available Previously published studies on the effect of short-term endurance training on the neuromuscular function of the plantar flexors have shown that the H-reflex elicited at rest and during weak voluntary contractions was increased following the training regime. However, these studies did not test H-reflex modulation during isometric maximum voluntary contraction (iMVC and did not incorporate a control group in their study design to compare the results of the endurance training group to individuals without the endurance training stimulus. Therefore, this randomized controlled study was directed to investigate the neuromuscular function of the plantar flexors at rest and during iMVC before and after eight weeks of cycling endurance training. Twenty-two young adults were randomly assigned to an intervention group and a control group. During neuromuscular testing, rate of torque development, isometric maximum voluntary torque and muscle activation were measured. Triceps surae muscle activation and tibialis anterior muscle co-activation were assessed by normalized root mean square of the EMG signal during the initial phase of contraction (0-100, 100-200 ms and isometric maximum voluntary contraction of the plantar flexors. Furthermore, evoked spinal reflex responses of the soleus muscle (H-reflex evoked at rest and during iMVC, V-wave, peak twitch torques induced by electrical stimulation of the posterior tibial nerve at rest and fatigue resistance were evaluated. The results indicate that the endurance training did not lead to a significant change in any variable of interest. Data of the present study conflict with the outcome of previously published studies that have found an increase in H-reflex excitability after endurance training. However, these studies had not included a control group in their study design as was the case here. It is concluded that short-term cycling endurance training does not necessarily enhance H-reflex responses and fatigue

    Full Text Available Short-term memory is a crucial cognitive function for supporting on-going and upcoming behaviours, allowing storage of information across delay periods. The content of this memory may typically include tangible information about features such as the shape, colour or texture of an object, its location and motion relative to the body, or phonological information. The neural correlate of these short-term memories has been found in different brain areas involved in organizing perceptual or motor functions. In particular, neuronal activity in different prefrontal areas encodes task-related information corresponding to short-term memory across delay periods, and lesions in the prefrontal cortex severely affect the ability to hold this type of memory. Recent studies have further expanded the scope and possible role of short-term memory by showing that information of abstract entities such as a behaviour-guiding rule, or the occurrence of a conflict in information processing; can also be maintained in short-term memory and used for adjusting the allocation of executive control in dynamic environments. It has also been shown that neuronal activity in the dorsolateral prefrontal and orbitofrontal cortices encodes information about such abstract entities. These findings suggest that the prefrontal cortex plays crucial roles in organizing goal-directed behaviour by supporting various mnemonic processes that maintain a wide range of information in the service of executive control of on-going or upcoming behaviour.

    Here we present a characterization of short-term stability of random Boolean networks under arbitrary distributions of transfer functions. Given any distribution of transfer functions for a random Boolean network, we present a formula that decides whether short-term chaos (damage spreading) will happen. We provide a formal proof for this formula, and empirically show that its predictions are accurate. Previous work only works for special cases of balanced families. Finally, it has been observed that these characterizations fail for unbalanced families, yet such families are widespread in real biological networks.

    Decompression and fusion is considered as the 'gold standard' for the treatment of degenerative lumbar diseases, however, many disadvantages have been reported in several studies, recently like donor site pain, pseudoarthrosis, nonunion, screw loosening, instrumentation failure, infection, adjacent segment disease (ASDis) and degeneration. Dynamic neutralization system (Dynesys) avoids many of these disadvantages. This system is made up of pedicle screws, polyethylene terephthalate cords, and polycarbonate urethane spacers to stabilize the functional spinal unit and preserve the adjacent motion after surgeries. This was a retrospective cohort study to compare the effect of Dynesys for treating degenerative lumbar diseases with posterior lumbar interbody fusion (PLIF) based on short term followup. Seventy five consecutive patients of lumbar degenerative disease operated between October 2010 and November 2012 were studied with a minimum followup of 2 years. Patients were divided into two groups according to the different surgeries. 30 patients underwent decompression and implantation of Dynesys in two levels (n = 29) or three levels (n = 1) and 45 patients underwent PLIF in two levels (n = 39) or three levels (n = 6). Clinical and radiographic outcomes between two groups were reviewed. Thirty patients (male:17, female:13) with a mean age of 55.96 ± 7.68 years were included in Dynesys group and the PLIF group included 45 patients (male:21, female:24) with a mean age of 54.69 ± 3.26 years. The average followup in Dynesys group and PLIF group was 2.22 ± 0.43 year (range 2-3.5 year) and 2.17 ± 0.76 year (range 2-3 year), respectively. Dynesys group showed a shorter operation time (141.06 ± 11.36 min vs. 176.98 ± 6.72 min, P degenerative disease showed clinical benefits with motion preservation of the operated segments, but does not have the significant advantage on motion preservation at adjacent segments, to avoid the degeneration of adjacent intervertebral disk.

    Previous neuropsychological studies produced inconsistent results with tasks tapping short-term verbal and visual-spatial memory and executive functions in obsessive compulsive disorder (OCD). The aim of this study was to investigate the presence of deficits in these cognitive domains. A further goal was to describe the distribution of patients in different impairment ranges for all functions, and clarify the relationship between symptom severity and cognitive impairments. Thirty patients with OCD (DSM-IV) and 30 healthy volunteers were compared using well-known neuropsychological tasks. We assessed short-term verbal memory with the Digit Span Forward and Digit Span Backward Tasks, short-term visual-spatial memory with the Corsi Block Tapping Task, while we measured the level of executive functions with the StroopTask and the Wisconsin Card Sorting Test (WCST). Compared with a matched healthy control group, the performance of OCD patients was in the impaired range only in the two executive tasks. We find a significant positive correlations between the Y-BOCS (Yale-Brown Obsessive Compulsive Scale) total scores and the number of perseverative responses (r(28) = 0.409, p short-term memory is intact in OCD. This is in line with neuropsychological model of OCD that the deficit of cognitive and behavioral inhibition are responsible for the main cognitive findings of this disorder, most prevalently the deficit in set shifting and prepotent response inhibition.

    The Accordion severity grading system is a novel system to score the severity of postoperative complications in a standardized fashion. This study aims to demonstrate the validity of the Accordion system in colorectal surgery by correlating severity grades with short-term outcomes after right colectomy for colon cancer. This is a retrospective cohort review of patients who underwent right colectomy for cancer between January 1, 2002, and January 31, 2007, at a single tertiary care referral center. Complications were categorized according to the Accordion severity grading system: grades 1 (mild), 2 (moderate), 3-5 (severe), and 6 (death). Outcome measures were hospital stay, 30-d readmission rate and 1-y survival. Correlation between Accordion grades and outcome measures is reflected by Spearman rho (ρ). One-year survival was obtained per Kaplan-Meier method and compared by logrank test for trend. Significance was set at P ≤ 0.05. Overall, 235 patients underwent right colectomy for cancer of which 122 (51.9%) had complications. In total, 52 (43%) had an Accordion grade 1 complication; 44 (36%) grade 2; four (3%) grade 3; 11 (9%) grade 4; seven (6%) grade 5; and four (3%) grade 6. There was significant correlation between Accordion grades and hospital stay (ρ = 0.495, P trend in 1-y survival as complication severity by Accordion grade increased (P = 0.02). The Accordion grading system is a useful tool to estimate short-term outcomes after right colectomy for cancer. High-grade Accordion complications are associated with longer hospital stay and increased risk of readmission and mortality. Published by Elsevier Inc.

    To identify clinical and radiologic findings that affect disease severity and short-term prognosis of humidifier disinfectant-associated lung injury in adults and to compare computed tomography (CT) findings between the patients with and without death or lung transplantation. Fifty-nine adults (mean age, 34 years; M/F = 12:47) were enrolled in this retrospective study. Medical records and prospective surveillance data were used to assess clinical and radiological factors associated with a poor clinical outcome. Multivariate generalized estimating equation models were used to analyse serial CT findings. Overall cumulative major events including lung transplantation and mortality were assessed using the Kaplan-Meier method. Almost half needed ICU admission (47.5 %) and 17 died (28.8 %). Young age, peripartum and low O_2 saturation were factors associated with ICU admission. On initial chest radiographs, consolidation (P < 0.001) and ground-glass opacity (P = 0.01) were significantly noted in patients who required ICU admission. CT findings including consolidation (odds ratio (OR), 1.02), pneumomediastinum (OR, 1.66) and pulmonary interstitial emphysema (OR, 1.61) were the risk factors for lung transplantation and mortality. Clinical and radiologic findings are related to the risks of lung transplantation and mortality of humidifier disinfectant-associated lung injury. Consolidation, pneumomediastinum and pulmonary interstitial emphysema were short-term prognostic CT findings. (orig.)

    Cerebral atrophy is a compound measure of the neurodegenerative component of multiple sclerosis (MS) and a conceivable outcome measure for clinical trials monitoring the effect of neuroprotective agents. In this study, we evaluate the rate of cerebral atrophy in a 6-month period, investigate the predictive and explanatory value of other magnetic resonance imaging (MRI) measures in relation to cerebral atrophy, and determine sample sizes for future short-term clinical trials using cerebral atrophy as primary outcome measure. One hundred thirty-five relapsing-remitting multiple sclerosis patients underwent six monthly MRI scans from which the percentage brain volume change (PBVC) and the number and volume of gadolinium (Gd)-enhancing lesions, T2 lesions, and persistent black holes (PBH) were determined. By means of multiple linear regression analysis, the relationship between focal MRI variables and PBVC was assessed. Sample size calculations were performed for all patients and subgroups selected for enhancement or a high T2 lesion load at baseline. A significant atrophy occurred over 6 months (PBVC = -0.33%, SE = 0.061, p < 0.0001). The number of baseline T2 lesions (p = 0.024), the on-study Gd-enhancing lesion volume (p = 0.044), and the number of on-study PBHs (p = 0.003) were associated with an increased rate of atrophy. For a 50% decrease in rate of atrophy, the sample size calculations showed that approximately 283 patients per arm are required in an unselected sampled population and 185 patients per arm are required in a selected population. Within a 6-month period, significant atrophy can be detected and on-study associations of PBVC and PBHs emphasizes axonal loss to be a driving mechanism. Application as primary outcome measure in short-term clinical trials with feasible sample size requires a potent drug to obtain sufficient power. (orig.)

    With the increased prevalence of obesity and sarcopenia, those patients with both visceral obesity and sarcopenia were at higher risk of adverse outcomes. The aim of this study was to ascertain the combined impact of visceral obesity and sarcopenia on short-term outcomes in patients undergoing colorectal cancer surgery. We conducted a prospective study from July 2014 to February 2017. Patients' demographic, clinical characteristics, physical performance, and postoperative short-term outcomes were collected. Patients were classified into four groups according to the presence of sarcopenia or visceral obesity. Clinical variables were compared. Univariate and multivariate analyses evaluating the risk factors for postoperative complications were performed. A total of 376 patients were included; 50.8 and 24.5% of the patients were identified as having "visceral obesity" and "sarcopenia," respectively. Patients with sarcopenia and visceral obesity had the highest incidence of total, surgical, and medical complications. Patients with sarcopenia or/and visceral obesity all had longer hospital stays and higher hospitalization costs. Age ≥ 65 years, visceral obesity, and sarcopenia were independent risk factors for total complications. Rectal cancer and visceral obesity were independent risk factors for surgical complications. Age ≥ 65 years and sarcopenia were independent risk factors for medical complications. Laparoscopy-assisted operation was a protective factor for total and medical complications. Patients with both visceral obesity and sarcopenia had a higher complication rate after colorectal cancer surgery. Age ≥ 65 years, visceral obesity, and sarcopenia were independent risk factors for total complications. Laparoscopy-assisted operation was a protective factor.

    To compare the perioperative and short-term oncological outcomes of patients who underwent single-port surgery (SPS) with those of patients who underwent multi-port surgery (MPS) for transverse colon cancer. The records of consecutive patients who underwent SPS (n = 75) or MPS (n = 41) for transverse colon cancer in our department between January, 2008 and December, 2015 were analyzed retrospectively. Operative times were significantly shorter in the SPS group than in the MPS group (185 vs. 195 min, respectively; P = 0.043). There were no significant differences in operative procedures, blood loss, or extent of lymph node dissection. The rate of postoperative complications was similar in both groups, but the length of hospital stay was significantly shorter in the single-port group than in the multi-port group (8 vs. 11 days, respectively; P transverse colon cancer.

    This study presents results of a family-centered, short-term residential program in which medical, behavioral, and treatment assessments were provided to the child with severe asthma and the family. After a median stay of 15 days, forty-four consecutively admitted children with severe asthma achieved a 93% reduction in hospital days (median, 7 hospital days for the year before treatment versus median 0 hospital days per patient per year at 20 1/2-month follow-up; p less than 0.001) and an 81% reduction in emergency care (median, 4 visits for the year previously versus median, 0.4 visits per patient per year at follow-up; p less than 0.01). There was also a significant reduction in corticosteroid bursts and improvement in FEV1. Unique to this program was mandatory family participation focusing on the child's and family's adaptation to severe asthma and development of family-specific interventions to promote compliance with the treatment regimen. Child and family functioning was assessed at admission and follow-up. Hospital use at follow-up was greater for children from dysfunctional families. Families demonstrating difficulties in disciplining the child with asthma required more hospital days both before admission and at follow-up. Short-term hospitalization for children with severe asthma is associated with significant improvement in pulmonary morbidity when the family of the child is included in assessment and treatment.

    Insight into the neural architecture of multitasking is crucial when investigating the pathophysiology of multitasking deficits in clinical populations. Presently, little is known about how the brain combines dual-tasking with a concurrent short-term memory task, despite the relevance of this mental operation in daily life and the frequency of complaints related to this process, in disease. In this study we aimed to examine how the brain responds when a memory task is added to dual-tasking. Thirty-three right-handed healthy volunteers (20 females, mean age 39.9 ± 5.8) were examined with functional brain imaging (fMRI). The paradigm consisted of two cross-modal single tasks (a visual and auditory temporal same-different task with short delay), a dual-task combining both single tasks simultaneously and a multi-task condition, combining the dual-task with an additional short-term memory task (temporal same-different visual task with long delay). Dual-tasking compared to both individual visual and auditory single tasks activated a predominantly right-sided fronto-parietal network and the cerebellum. When adding the additional short-term memory task, a larger and more bilateral frontoparietal network was recruited. We found enhanced activity during multitasking in components of the network that were already involved in dual-tasking, suggesting increased working memory demands, as well as recruitment of multitask-specific components including areas that are likely to be involved in online holding of visual stimuli in short-term memory such as occipito-temporal cortex. These results confirm concurrent neural processing of a visual short-term memory task during dual-tasking and provide evidence for an effective fMRI multitasking paradigm. © 2013 Elsevier Ltd.

    Objective: To assess short-term outcomes after lung transplantation with organs procured following brain death. Methods: Between April 2015 and July 2016, all 17 recipients after lung transplantation using organs from brain death donors (DBD) at Department of Thoracic Surgery, Shanghai Pulmonary Hospital, Tongji University School of Medicine were enrolled in this study. All patients were male, aging (60±7) years, including 11 chronic obstructive pulmonary disease, 5 idiopathic pulmonary fibrosis, 1 silicosis. Seventeen donors were 16 males and 1 female, with 10 traumatic brain injury, 5 cerebrovascular accident and 2 sudden cardiac death. Of 17 recipients receiving DBD lung transplant, 16 were single lung transplant. Data were collected including intubation duration of mechanical ventilation, hospital length of stay, incidence of pulmonary infection bronchus anastomosis complications, primary graft dysfunction (PGD), and acute rejection, bronchiolitis obliterans syndrome (BOS) as well as mortality of 90-day after lung transplantation. Results: Median duration of intubation were 2 (2) days ( M ( Q R )) in recipients after lung transplantation. The incidence of pulmonary infection and bronchus anastomosis complications were 15/17 and 5/17, respectively. Median length of stay in hospital were 56 (19) days. The ratio of readmission 1 month after discharge were 10/17. Mortality of 90-day post-transplant were 2/17. The incidence of PGD and BOS were 1/17 and 2/17, respectively. Conclusion: Recipients with DBD lung transplantation have an acceptable survival during short-term follow-up, but with higher incidences of complications related to infection post-transplantation.

    We sought to analyse the effect of pretransplant diabetes on post-operative outcomes and resource utilization following liver transplantation. A retrospective cohort study was designed using a linkage between the University HealthSystem Consortium and Scientific Registry of Transplant Recipients databases. We identified 12 442 patients who underwent liver transplantation at 63 centres from 2007-2011 and separated cohorts of patients with diabetes (n = 2971; 24%) and without (n = 9471; 76%) at the time of transplant. We analysed transplant related outcomes and short-term survival. Diabetic recipients were more likely to be male (70% vs 67%), non-white (32% vs 26%), older (age ≥60; 41% vs 28%), and have a higher BMI (29 vs 27; P diabetic patients were on haemodialysis (10% vs 7%), had cirrhosis caused by NASH (24% vs 9%; P 1.49; 46% vs 42%; P diabetic recipients had longer hospital length of stay (10 vs 9 days), higher peri-transplant mortality (5% vs 4%) and 30-day readmission rates (41% vs 37%), were less often discharged to home (83% vs 87%; P diabetics ($105 078 vs $100 624, P diabetic recipients were less likely discharged home following transplant (75% vs 82%, P diabetes is associated with inferior post-operative outcomes and increased resource utilization after liver transplantation. © 2014 John Wiley & Sons A/S.

    We aimed to clarify whether the short-term adverse neonatal outcomes associated with epidural analgesia are due to the epidural analgesia itself or to the instrumental delivery. A retrospective case-control study was conducted to evaluate the relationship between epidural analgesia, labor length, and perinatal outcomes. A total of 350 pregnant women at term who delivered under epidural analgesia (cases) were compared with 1400 patients without epidural analgesia (controls). Vacuum extraction (6.5 vs. 2.9 %) and cesarean section (19.9 vs. 11.1 %) were more frequently performed in the cases than controls (p neonatal variables stratified by mode of delivery were not different in cases and controls, except for a slightly lower umbilical arterial pH in spontaneous delivery for the cases group. However, the Apgar scores and umbilical arterial pH were significantly lower in the neonates delivered by vacuum extraction compared with those in the neonates delivered by spontaneous delivery or cesarean section, regardless of whether epidural analgesia was performed. A multivariable analysis showed that vacuum extraction much more consistently affected the arterial pH than the analgesia itself (the β coefficients were -0.036 for epidural analgesia vs. -0.050 for vacuum extraction). Epidural analgesia was associated with slowly progressing labor, thus resulting in an increased rate of instrumental delivery. This instrumental delivery appears to adversely affect the neonatal outcomes more strongly than the analgesia itself.

    Meditation improves executive functions such as attention and working memory processes. However, it remains unclear to what extent contextual effects contribute to these improvements, since the role of meditation-associated expectations has not been investigated so far. In a randomized, single-blind, deceptive, between-subject design we compared the impact of short-term meditation (MG) on executive functioning with an expectation (ECG) and a passive control group (CG) as well as the effect of positive and negative outcome expectations. Fifty-nine healthy meditation-naïve volunteers participated on three consecutive days (20 min/session). Five groups were examined: 2 MGs, 2 ECGs and 1 CG. While one MG and one ECG were given positive suggestions concerning the effect of meditation on attention, the other two groups were given negative suggestions. MGs practised a focused attention meditation technique; ECGs were told that they were practising meditation but were given instructions for a sham meditation. CG participants sat in silence with their eyes closed. Interference control (Stroop task), selective sustained attention (d2 task), figural and verbal fluency measures of executive functions were assessed. Results indicate that suggestions have a substantial impact on interference control and verbal fluency, with positive suggestions leading to an increase in performance, whereas negative suggestions impeded improvement. This proof of concept study demonstrates the importance of the implementation of a credible ECG to elucidate context effects in meditation processes. It also indicates that suggestions can modulate the small effect of meditation on verbal fluency. Copyright © 2015 Elsevier B.V. All rights reserved.

    Data regarding the effect of opium use on short-term outcome in patients undergoing coronary artery bypass surgery are limited. We sought to assess the morbidity and in-hospital mortality of current and past users compared the data with those from nonusers of opium after coronary artery bypass grafting (CABG). This is a descriptive analytical review of prospectively collected data on 782 consecutive male patients who underwent isolated CABG between January 2005 and December 2007. Of these, 708 (90.5%) were nonusers, 56 (7.1%) were current users, and 18 (2.3%) were former opium users of more than 4 weeks. The effect of opium usage on clinical, admission, and outcome variables were analyzed. Current opium users were younger (P = 0.004) and more likely to be cigarette smokers (P = 0.0004). Other demographic characteristics, major coronary risk factors, rates of postoperative complications, intensive care unit readmission, postoperative length of stay, and in-hospital mortality did not differ among the three groups. Current opium users needed less analgesic postoperatively (P = 0.0001), were significantly less compliant with medical and dietary recommendations after discharge (P opium (P opium is a significant predictor of rehospitalization with a cardiac cause within 6 months of CABG surgery. This may be partly due to the low compliance of these patients with treatment recommendations.

    Full Text Available Background: Untreated Perthes disease can lead to osteoarthritis by the fourth decade. The treatment is conservative for children 10 years of age at presentation. All patients had limitation of abduction and internal rotation. Eight patients (53.33% had pain at the hip and 12 patients (80% had limp. Mean time between diagnosis and corrective surgery was 3 weeks. Results: The evaluation was done using caput index (CI and epiphyseal quotient (EQ and articulotrochanteric distance radiologically, range of motion and Harris Hip Score for clinical outcome. All the measurements were carried out on pre- and postoperative X-rays after 3 years followup and compared with the contralateral normal hip. After a mean followup period of 3.4 years, we noted the statistically significant difference between pre- and postoperative values. We noted that all (100% children in Stage IB, IIA and 50% children in Stage IIB achieved satisfactory results. There was a significant change (P = 0.000 in CI among all the patients after surgery. The final EQ after 3 years of VDRO was 0.606 and was significant (P = 0.0000. Conclusion: In our opinion, based on the encouraging short term radiological and clinical outcomes, VDRO may be regarded as a treatment procedure for late presenting Perthes disease in stage IB, IIA, IIB.

    To determine if readiness for change (RFC) at admission predicted length of stay (LOS) and short-term outcomes among female adolescents in residential treatment for anorexia nervosa (AN). Using a prospective cohort design to collect data from participants (N = 65) at admission and discharge, Kaplan-Meier survival analysis and Cox regression tested whether RFC on admission predicted time in LOS to a favorable short-term outcome--a composite endpoint based on minimum criteria for weight gain, drive for thinness, depression, anxiety, and health-related quality of life (HRQOL). Participants with low RFC had a mean survival time to a favorable short-term outcome of 59.4 days compared to 34.1 days for those with high RFC (log rank = 8.44, df = 1, p = .003). The probability of a favorable short-term outcome was 5.30 times greater for participants with high RFC. Readiness for change is a useful predictor of a favorable short-term outcome and should be considered in the assessment profile of patients with AN. (c) 2007 by Wiley Periodicals, Inc.

    There is an important need for objective parameters that accurately predict the outcome of horses with large colon volvulus. To evaluate the predictive value of a series of histomorphometric parameters on short-term outcome, as well as the impact of colonic resection on horses with large colon volvulus. Retrospective cohort study. Adult horses admitted to the Equine and Farm Animal Veterinary Center at North Carolina State University, Peterson and Smith and Chino Valley Equine Hospitals between 2006 and 2013 that underwent an exploratory coeliotomy, diagnosed with large colon volvulus of ≥360 degrees, where a pelvic flexure biopsy was obtained, and that recovered from general anaesthesia, were selected for inclusion in the study. Logistic regression was used to determine associations between signalment, histomorphometric measurements of interstitium-to-crypt ratio, degree of haemorrhage, percentage loss of luminal and glandular epithelium, as well as colonic resection with short-term outcome (discharge from the hospital). Pelvic flexure biopsies from 47 horses with large colon volvulus were evaluated. Factors that were significantly associated with short-term outcome on univariate logistic regression were Thoroughbred breed (P = 0.04), interstitium-to-crypt ratio >1 (P = 0.02) and haemorrhage score ≥3 (P = 0.005). Resection (P = 0.92) was not found to be associated significantly with short-term outcome. No combined factors increased the likelihood of death in forward stepwise logistic regression modelling. A digitally quantified measurement of haemorrhage area strengthened the association of haemorrhage with nonsurvival in cases of large colon volvulus. Histomorphometric measurements of interstitium-to-crypt ratio and degree of haemorrhage predict short-term outcome in cases of large colon volvulus. Resection was not associated with short-term outcome in horses selected for this study. Accurate quantification of mucosal haemorrhage at the time of surgery may

    This study investigated gender inequality in biology lessons and analysed the effects of the observed inequality on students' short-term knowledge achievement, situational interest and students' evaluation of teaching (SET). Twenty-two biology teachers and 803 7th-grade students from rural and urban classrooms in China participated in the study. Each teacher was videotaped for 1 lesson on the topic blood and circulatory system. Before and after the lessons, the students completed tests and questionnaires. Chi-square analysis was conducted to compare the boys' and girls' participation rates of answering teachers' questions in the lessons. The findings revealed that in the urban classrooms the boys had a significantly higher rate of participation than did the girls, and hence also a higher situational interest. However, no such gender inequity was found among the rural students. The study also revealed that urban students answered more complicated questions compared with the rural students in general. The findings of this study suggest that the teachers should try to balance boys' and girls' participation and involve more students in answering questions in their lessons. The study also raises questions about long-term effects of students' participation in answering teachers' questions on their outcomes-knowledge achievement, situational interest and SET.

    To describe surgical techniques for multiple port laparoscopic splenectomy (MLS) in dogs and report short-term outcome. Retrospective case series. Dogs (n = 10) with naturally occurring splenic disease. Medical records (March 2012-March 2013) of dogs that had MLS were reviewed. Data retrieved included signalment, weight, clinical signs, physical examination findings, preoperative laboratory and ultrasonographic findings, port number, size, and location, patient positioning, additional procedures performed, surgical duration, histopathologic diagnosis, duration of hospitalization, and perioperative complications. Ten dogs (median weight, 28.7 kg; range, 20.2-46.0 kg) had MLS using a 3 or 4 port technique and a vessel-sealing device for tissue dissection along the splenic hilus. Dog positioning varied because of additional laparoscopic or laparoscopic-assisted procedures including adrenalectomy (n = 2), ovariectomy (1), gastropexy (1), and intestinal resection and anastomosis (1). Conversion to an open approach was necessary in 1 dog because of inadequate visibility caused by omental adhesions. One dog had hemorrhage from an omental vessel, but open conversion was not required. MLS was associated with little perioperative morbidity and few complications in this cohort of dogs and may be a reasonable option for surgical management of dogs requiring elective splenectomy. © Copyright 2014 by The American College of Veterinary Surgeons.

    To compare the safety and efficacy of robotic-assisted distal pancreatectomy (RADP) and laparoscopic distal pancreatectomy (LDP). A literature search of PubMed, EMBASE, and the Cochrane Library database up to June 30, 2015 was performed. The following key words were used: pancreas, distal pancreatectomy, pancreatic, laparoscopic, laparoscopy, robotic, and robotic-assisted. Fixed and random effects models were applied. Study quality was assessed using the Newcastle-Ottawa Scale. Seven non-randomized controlled trials involving 568 patients met the inclusion criteria. Compared with LDP, RADP was associated with longer operating time, lower estimated blood loss, a higher spleen-preservation rate, and shorter hospital stay. There was no significant difference in transfusion, conversion to open surgery, R0 resection rate, lymph nodes harvested, overall complications, severe complications, pancreatic fistula, severe pancreatic fistula, ICU stay, total cost, and 30-day mortality between the two groups. RADP is a safe and feasible alternative to LDP with regard to short-term outcomes. Further studies on the long-term outcomes of these surgical techniques are required. To date, there is no consensus on whether laparoscopic or robotic-assisted distal pancreatectomy is more beneficial to the patient. This is the first meta-analysis to compare laparoscopic and robotic-assisted distal pancreatectomy. We found that robotic-assisted distal pancreatectomy was associated with longer operating time, lower estimated blood loss, a higher spleen-preservation rate, and shorter hospital stay. There was no significant difference in transfusion, conversion to open surgery, overall complications, severe complications, pancreatic fistula, severe pancreatic fistula, ICU stay, total cost, and 30-day mortality between the two groups.

    Most adolescent gynecomastia is resolved spontaneously in 3 years. But, persistent gynecomastia could have a negative influence on psychoemotional development on adolescence. The purpose of this study is to report the characteristics of adolescent gynecomastia patients who received the surgeries, and discuss the short-term surgical outcomes. Of the 1454 patients who underwent gynecomastia surgery at Damsoyu hospital from January 2014 to May 2016, 71 were adolescents. Subcutaneous mastectomy with liposuction was performed for adolescent patients who had gynecomastia for more than 3 years and showed psychosocial distress. Demographic and outcome variables were retrospectively analyzed. The mean age was 17.5 ± 0.77 years old. All gynecomastia cases were bilateral. Simon's grade IIa (35 patients, 49.3%) was the most common, and grade III was not observed. Fifty-one patients (71.8%) were classified as having a glandular-type breast component. Fourteen patients (19.7%) had complications, but only 3 cases (4.2%) required revision. Most of the patients (70 patients, 98.6%) were satisfied with the esthetic results, and the average 5-point Likert score was 4.85 ± 0.40. Recurrence was not observed. As the Simon's grade increased from I to IIA, a higher BMI, larger amounts of breast tissue, and longer operation times were observed. Gynecomastia that did not regress spontaneously was mostly the glandular type, so not only liposuction but also surgical removal of glandular tissue is necessary. Surgical treatment, selectively performed in patients who have had gynecomastia for 3 years, and have experienced psychosocial distress, could be an acceptable treatment for adolescent gynecomastia.

    Laparoscopic colectomy for both benign and malignant disease, including inflammatory bowel disease (IBD), has recently been shown to have many advantages compared with open surgery. This study aimed to compare the effect of laparoscopic versus open subtotal colectomy (STC) for IBD on overall morbidity. A total of 99 patients undergoing STC for IBD at our institution from 2007 through 2011 were identified. Patients undergoing open STC were compared with patients undergoing laparoscopic STC. Outcomes included 30-day morbidity, conversion to laparotomy, intraoperative blood loss, operative time, admission time, late onset complications and 30-day mortality. Results are presented as median values. A total of 57 patients underwent open STC (Group 1) and 42 patients laparoscopic STC (Group 2). Group 1 comprised 26 males and 31 females, with a median age of 35 years and a body mass index (BMI) of 23.2 kg/m2. Group 2 comprised 18 males and 24 females, with a median age of 34 years and a BMI of 23.5 kg/m2. Group 2 had less morbidity (42.9% versus 75.4%, p < 0.002), reduced blood loss (100 ml versus 200 ml, p < 0.001), longer operative time (193.5 min. versus 128 min., p < 0.001), shorter length of hospital stay (six days versus 16 days, p < 0.001) than Group 1. One patient died (Group 1). There was no difference in late onset complications and no conversions to laparotomy in the laparoscopic group. Laparoscopic STC has a longer operative time, but improves short-term outcomes compared with open surgery. not relevant. not relevant.

    Seizures are common among critically ill children, but their relationship to outcome remains unclear. We sought to quantify the relationship between electrographic seizure burden and short-term neurological outcome, while controlling for diagnosis and illness severity. Furthermore, we sought to determine whether there is a seizure burden threshold above which there is an increased probability of neurological decline. We prospectively evaluated all infants and children admitted to our paediatric and cardiac intensive care units who underwent clinically ordered continuous video-electroencephalography monitoring over a 3-year period. Seizure burden was quantified by calculating the maximum percentage of any hour that was occupied by electrographic seizures. Outcome measures included neurological decline, defined as a worsening Paediatric Cerebral Performance Category score between hospital admission and discharge, and in-hospital mortality. Two hundred and fifty-nine subjects were evaluated (51% male) with a median age of 2.2 years (interquartile range: 0.3 days–9.7 years). The median duration of continuous video-electroencephalography monitoring was 37 h (interquartile range: 21–56 h). Seizures occurred in 93 subjects (36%, 95% confidence interval = 30–42%), with 23 (9%, 95% confidence interval = 5–12%) experiencing status epilepticus. Neurological decline was observed in 174 subjects (67%), who had a mean maximum seizure burden of 15.7% per hour, compared to 1.8% per hour for those without neurological decline (P seizure burden threshold of 20% per hour (12 min), both the probability and magnitude of neurological decline rose sharply (P seizure burden. Seizure burden was not associated with mortality (odds ratio: 1.003, 95% confidence interval: 0.99–1.02, P = 0.613). We conclude that in this cohort of critically ill children, increasing seizure burden was independently associated with a greater probability and magnitude of neurological decline. Our

    Purpose To examine predictors of psychotherapy outcomes, focusing on client characteristics that are especially salient for culturally diverse clients. Method Sixty clients (31 women; 27 White Americans, 33 Asian Americans) participated in this treatment study. Client characteristics were measured at pre-treatment, and outcomes were measured post-fourth session via therapist ratings of functioning and symptomatology. Regression analyses were utilized to test for predictors of outcomes, and bootstrap analyses were utilized to test for mediators. Results Higher levels of somatic symptoms predicted lower psychosocial functioning at post-treatment. Avoidant coping style predicted more negative symptoms and more psychological discomfort. Non-English language preference predicted worse outcomes; this effect was mediated by an avoidant coping style. Conclusions Language preference, avoidant coping style, and somatic symptoms predicted treatment outcome in a culturally diverse sample. Findings suggest that race/ethnicity-related variables may function through mediating proximal variables to affect outcomes. PMID:22836681

    The Thompson encephalopathy score is a clinical score to assess newborns suffering from perinatal asphyxia. Previous studies revealed a high sensitivity and specificity of the Thompson encephalopathy score for adverse outcomes (death or severe disability). Because the Thompson encephalopathy score was developed before the use of therapeutic hypothermia, its value was reassessed. The purpose of this study was to assess the association of the Thompson encephalopathy score with adverse short-term outcomes, defined as death before discharge, development of severe epilepsy, or the presence of multiple organ failure in asphyxiated newborns undergoing therapeutic hypothermia. The study period ranged from November 2010 to October 2014. A total of 12 tertiary neonatal intensive care units participated. Demographic and clinical data were collected from the "PharmaCool" multicenter study, an observational cohort study analyzing pharmacokinetics of medication during therapeutic hypothermia. With multiple logistic regression analyses the association of the Thompson encephalopathy scores with outcomes was studied. Data of 142 newborns were analyzed (male: 86; female: 56). Median Thompson score was 9 (interquartile range: 8 to 12). Median gestational age was 40 weeks (interquartile range 38 to 41), mean birth weight was 3362 grams (standard deviation: 605). All newborns manifested perinatal asphyxia and underwent therapeutic hypothermia. Death before discharge occurred in 23.9% and severe epilepsy in 21.1% of the cases. In total, 59.2% of the patients had multiple organ failure. The Thompson encephalopathy score was not associated with multiple organ failure, but a Thompson encephalopathy score ≥12 was associated with death before discharge (odds ratio: 3.9; confidence interval: 1.3 to 11.2) and with development of severe epilepsy (odds ratio: 8.4; confidence interval: 2.5 to 27.8). The Thompson encephalopathy score is a useful clinical tool, even in cooled asphyxiated

    Our pilot study aims to investigate the efficacy of a Short-Term (4 weeks) Psychiatric Rehabilitation Program (S-T PsyRP), without specific cognitive remediation trainings, on the neuropsychological performance and psychosocial functioning of inpatients with Major Depressive Disorder (MDD) or Bipolar Disorder (BD). Published studies with similar aims are lacking. Fifty-three inpatients with MDD and 27 with BD (type I/II) were included. The S-T PsyRP was usually performed as clinical practice at Villa San Benedetto Menni Hospital and included a variety of activities aimed at promoting personal autonomies, interpersonal/social skills, and self-care. At the beginning and the end of the hospitalization we evaluated: neuropsychological performance (cognitive tests on verbal/visual working memory, attention, visual-constructive ability, language fluency, and comprehension); psychosocial functioning by the Rehabilitation Areas Form (RAF, handbook VADO); illness severity by the Brief Psychiatric Rating Scale (BPRS). Repeated-measure ANOVA and Pearson's linear correlation were used. We found significant improvement (pneuropsychological tests except for one, in 4 out of 6 RAF psychosocial areas ("involvement in ward activities", "autonomies", "self-care", and "self-management of health") and in clinical symptoms severity. No associations were found between the amelioration of clinical symptoms and neuropsychological or psychosocial improvement. A S-T PsyRP without specific cognitive remediation trainings may improve several cognitive/functional domains in MDD or BD inpatients, probably by offering opportunities to engage in demanding problem-solving conditions and cognitively stimulating activities.

    Catatonia is a potentially life-threatening but treatable neuropsychiatric condition. Although considered more common in low income countries, data is particularly sparse in these settings. In this study we explore the symptomatology, treatment, and short-term outcome of catatonia in Ethiopia, a low income country. The study was a prospective evaluation of patients admitted with a DSM-IV diagnosis of catatonia. Diagnosis of Catatonia and its severity were further assessed with the Bush-Francis Catatonia Rating Scale (BFCRS). Twenty participants, 5 male and 15 female, were included in the study: 15 patients (75 %) had underlying mood disorders, 4 patients (20 %) had schizophrenia and 1 patient (5 %) had general medical condition. The most common catatonic symptoms, occurring in over two-thirds of participants, were mutism, negativism, staring and immobility (stupor). Eighteen (90 %) of the twenty patients were on multiple medications. Antipsychotics were the most commonly prescribed medications. ECT was required in seven patients (35.0 %). Dehydration, requiring IV rehydration, and infections were the most important complications ascribed to the catatonia. These occurred in seven patients (25 %). Almost all patients (n = 19/20) were discharged with significant improvement. This study supports the growing consensus that catatonia is most often associated with mood disorders. Overall prognosis appears very good although the occurrence of life-threatening complications underlines the serious nature of catatonia. This has implication for "task-shifted" service scale up plans, which aim to improve treatment coverage by training non-specialist health workers to provide mental health care in low income countries. Further larger scale studies are required to clarify the nature and management, as well as, service requirements for catatonia.

    Full Text Available Background: Participation in research during undergraduate studies may increase students′ interest in research and inculcate research essentials in them. Aims: The purpose of this study was to evaluate the effectiveness of the mentored student project (MSP program. Settings and Design: In the MSP program, students in groups (n = 3 to 5 undertook a research project, wrote a scholarly report, and presented the work as a poster presentation with the help of a faculty mentor. To begin with, the logic model of the program was developed to identify short-term outcomes of the program on students, mentors, and the institution. A quasi-experimental design was used to measure the outcomes. Materials and Methods: A mixed method evaluation was done using a newly-developed questionnaire to assess the impact of the MSP on students′ attitude, a multiple-choice question (MCQs test to find out the impact on students′ knowledge and grading of students′ project reports and posters along with a survey to check the impact on skills. Students′ satisfaction regarding the program and mentors′ perceptions were collected using questionnaires. Evidence for validity was collected for all the instruments used for the evaluation. Statistical Analysis: Non-parametric tests were used to analyze data. Based on the scores, project reports and posters were graded into A (>70% marks, B (60-69% marks, and C (<59% marks categories. The number of MSPs that resulted in publications, conference presentation and departmental collaborations were taken as impact on the institution. Results: Students′ response rate was 91.5%. The students′ attitudes regarding research changed positively (P = 0.036 and score in the MCQ test improved (P < 0.001 after undertaking MSP. Majority of project reports and posters were of grade A category. The majority of the items related to skills gained and satisfaction had a median score of 4.

    We compare the early and midterm outcomes of pulmonary thromboembolism (PTE) in patients with and without syncope in our single-center registry. Between December 2006 and May 2013, 351 consecutive patients (mean age = 60.21 ± 16.91 years, 55.3% male) with confirmed acute symptomatic PTE were divided in with and without syncope groups. Groups were compared in terms of the effect of syncope on 30-day mortality and adverse events, and mortality in a median follow-up time of 16.9 months. From 351 patients, 39 (11.1%) had syncope and 312 (88.9%) did not. Syncope group had less frequently chest pain (30.8% vs 51.4%; P value = 0.015). Also, the rates of 30-day adverse events and mortality were 12.8% and 5.1% for the group with syncope, and 14.4% and 10.3% for the group without syncope, respectively, with no significant difference. At follow up, 65 patients died and mortality was 18.5% for 351 patients (5.1% in the group with syncope and 20.2% for the other group). After adjustment for confounding factors, the effect of syncope on 30-day adverse events and mortality remained non-significant and on the midterm mortality was significant, showing that the presence of syncope was associated with lower midterm mortality (P value = 0.038). Among PTE patients in our registry, 11.1% presented with syncope. Relationship between syncope and 30-day adverse events and mortality remained non-significant after adjustments for other factors. However, in midterm follow up, patients with syncope were significantly at decreased risk of mortality compared to those without syncope. © 2014 John Wiley & Sons Ltd.

    We investigated associations between ambient air pollution and microvessel function measured by peripheral arterial tonometry between 2003 and 2008 in the Framingham Heart Study Offspring and Third Generation Cohorts. We measured particulate matter with aerodynamic diameter ≤2.5 µm (PM2.5), black carbon, sulfates, particle number, nitrogen oxides, and ozone by using fixed monitors, and we determined moving averages for 1-7 days preceding vascular testing. We examined associations between these exposures and hyperemic response to ischemia and baseline pulse amplitude, a measure of arterial tone (n = 2,369). Higher short-term exposure to air pollutants, including PM2.5, black carbon, and particle number was associated with higher baseline pulse amplitude. For example, higher 3-day average PM2.5 exposure was associated with 6.3% higher baseline pulse amplitude (95% confidence interval: 2.0, 10.9). However, there were no consistent associations between the air pollution exposures assessed and hyperemic response. Our findings in a community-based sample exposed to relatively low pollution levels suggest that short-term exposure to ambient particulate pollution is not associated with vasodilator response, but that particulate air pollution is associated with baseline pulse amplitude, suggesting potentially adverse alterations in baseline vascular tone or compliance. © The Author 2014.

    Studies in fetuses and in prematurely born infants show that auditory discriminative skills are present prior to birth. The magnetic fields generated by the fetal brain activity pass the maternal tissues and, despite their weakness, can be detected externally using MEG. Recent studies on the auditory evoked magnetic responses show that the fetal brain responds to sound onset. In contrast, higher-level auditory skills, such as those involving discriminative and memory functions, were not so far studied in fetuses with MEG. Here we show that fetal responses related to discriminating sounds can be recorded, implicating that the auditory change-detection system is functional. These results open new views to developmental neuroscience by enabling one to determine the sensory capabilities as well as the extent and accuracy of the short-term memory system of the fetus, and, further, to follow the development of these crucial processes.

    To evaluate the short-term therapeutic effectiveness of ovarian vein embolization using coils for pelvic congestion syndrome (PCS), a common cause of chronic pelvic pain, and to determine patient satisfaction. Forty-four multiparous women aged 26-73 (mean, 39.9) years in whom chronic pelvic pain due to unknown causes had lasted for more than six months, and whose gynecologic findings and laboratory data suggested PCS, underwent transabdominal or transvaginal ultrasonography and selective ovarian venography. PSC was finally diagnosed in 21 of th 44, who underwent 22 ovarian vein embolizations (in one case, bilaterally). The simple pain rating system was used at admission, with a 'minimal' or 'moderate' grade representing discomfort in daily life, and 'severe; indicating the need for medication. Indications for coil embolization included dilatation of the ovarian vein to a diameter of more than 6 mm, reflux involving an incompetent valve, congestion of the pelvic venous plexus (involving the stasis of contrast media), and /or opacification of the ipsilateral internal iliac vein (or contralateral filling). Embolizations were undertaken using coils of optimal size and number, and the mean follow-up period was 217 (31-267) days. By means of a telephone questionnaire, the outcome was classified as a cure, pain reduction, or 'no change, or aggravation', and on the basis of whether or not they would opt for the same treatment, or recommend embolization to others, patient satisfaction was graded as 'substantial', 'moderate', or 'absent'. Venous occlusion was confirmed at postembolization venography in all 22 cases. Clinical treatment led to symptomatic relief in 76.2% of patients a cure in 33.3%(7/21), pain reduction in 42.9%(9/21) and no imchage, or aggravation, in 23.8%(5/21). Eighteen patients (85.5%) were very (9/21, 42.9%) or moderately (9/21, 42.9%) satisfied with coil embolization. In two, the coil

    Objective: To determine the short-term neonatal outcomes in late preterm infants (LPIs) as compared to term infants and their association with maternal risk factors. Study Design: A case control, descriptive study. Place and Duration of Study: The Aga Khan University Hospital, Karachi, Pakistan, from January to December 2009. Methodology: The study included 326 late preterm babies (defined as those born between 34 to 37 weeks of gestation) and equal number of term control babies at the Aga Khan University Hospital, Karachi, Pakistan. Data, including obstetric history, maternal complications, neonatal morbidities, etc., was retrieved from patients medical records. The data was compared with the control group for complications, fetal morbidity and maternal morbidity. Results: Late preterm infants constituted 10.6% of all deliveries and 77% of all live preterm births during the study period. Respiratory distress syndrome (RDS) (16.5% vs. 0.3%, p < 0.001), growth retardation (24.8% vs. 4%, p < 0.001), hyperbilirubinemia requiring phototherapy (37.9% vs. 11%, p < 0.001), and sepsis (4.9% vs. 0.3%, p < 0.001) were found to be the major morbidities in the study group. The need for resuscitation was 12.7 times higher in the study group as compared to the term babies (21.4% vs. 1.2%, p < 0.001). NICU admissions in the study group were also higher (18.8% vs. 2.4%, p < 0.001). Hypertension (12.5% vs. 1.5%, p < 0.001), diabetes (12.5% vs. 9.2%, p < 0.001), antenatal history of UTI (1.5% vs. 0.3%, p < 0.001), and prolong rupture of membrane (8.9% vs. 4%, p < 0.001) were significant maternal morbidities in the late preterm group. Conclusion: The late preterm group had greater morbidity, compared to term neonates. Prior awareness of the morbidities associated with late preterm babies is helpful for the health care providers to anticipate and manage potential complications in late preterm infants. (author)

    To evaluate the short-term therapeutic effectiveness of ovarian vein embolization using coils for pelvic congestion syndrome (PCS), a common cause of chronic pelvic pain, and to determine patient satisfaction. Forty-four multiparous women aged 26-73 (mean, 39.9) years in whom chronic pelvic pain due to unknown causes had lasted for more than six months, and whose gynecologic findings and laboratory data suggested PCS, underwent transabdominal or transvaginal ultrasonography and selective ovarian venography. PSC was finally diagnosed in 21 of th 44, who underwent 22 ovarian vein embolizations (in one case, bilaterally). The simple pain rating system was used at admission, with a 'minimal' or 'moderate' grade representing discomfort in daily life, and 'severe; indicating the need for medication. Indications for coil embolization included dilatation of the ovarian vein to a diameter of more than 6 mm, reflux involving an incompetent valve, congestion of the pelvic venous plexus (involving the stasis of contrast media), and /or opacification of the ipsilateral internal iliac vein (or contralateral filling). Embolizations were undertaken using coils of optimal size and number, and the mean follow-up period was 217 (31-267) days. By means of a telephone questionnaire, the outcome was classified as a cure, pain reduction, or 'no change, or aggravation', and on the basis of whether or not they would opt for the same treatment, or recommend embolization to others, patient satisfaction was graded as 'substantial', 'moderate', or 'absent'. Venous occlusion was confirmed at postembolization venography in all 22 cases. Clinical treatment led to symptomatic relief in 76.2% of patients a cure in 33.3%(7/21), pain reduction in 42.9%(9/21) and no imchage, or aggravation, in 23.8%(5/21). Eighteen patients (85.5%) were very (9/21, 42.9%) or moderately (9/21, 42.9%) satisfied with coil embolization. In two, the coil migrated, and was successfully retrieved using a snare loop. In this

    Recent evidence suggests that functional and silent synapses are not only postsynaptically different but also presynaptically distinct. The presynaptic differences may be of functional importance in memory formation because a proposed mechanism for long-term potentiation is the conversion of silent synapses into functional ones. However, there is little direct experimentally evidence of these differences. We have investigated the transmitter release properties of functional and silent Schaffer collateral synapses and show that on the average functional synapses displayed a lower percentage of failures and higher excitatory postsynaptic current (EPSC) amplitudes than silent synapses at +60 mV. Moreover, functional but not silent synapses show paired-pulse facilitation (PPF) at +60 mV and thus presynaptic short-term plasticity will be distinct in the two types of synapse. We examined whether intraterminal endoplasmic reticulum Ca2+ stores influenced the release properties of these synapses. Ryanodine (100 microM) and thapsigargin (1 microM) increased the percentage of failures and decreased both the EPSC amplitude and PPF in functional synapses. Caffeine (10 mM) had the opposite effects. In contrast, silent synapses were insensitive to both ryanodine and caffeine. Hence we have identified differences in the release properties of functional and silent synapses, suggesting that synaptic terminals of functional synapses express regulatory molecular mechanisms that are absent in silent synapses.

    This study investigated changes in brain function that occurred over a 7-day behavioral intervention for adults who stutter (AWS). Thirteen AWS received the intervention (AWS+), and 13 AWS did not receive the intervention (AWS-). There were 13 fluent controls (FC-). All participants were scanned before and after the intervention. Whole-brain analysis pre-intervention showed significant differences in task-related brain activation between AWS and FC- in the right inferior frontal cortex (IFC) and left middle temporal cortex, but there were no differences between the two AWS groups. Across the 7-day period of the intervention, AWS+ alone showed a significant increase of brain activation in the left ventral IFC/insula. There were no changes in brain function for the other two groups. Further analysis revealed that the change did not correlate with resting-state functional connectivity (RSFC) that AWS showed in the cerebellum (Lu et al., 2012). However, both changes in task-related brain function and RSFC correlated with changes in speech fluency level. Together, these findings suggest that functional reorganization in a brain region close to the left IFC that shows anomalous function in AWS, occurs after a short-term behavioral intervention for stuttering.

    Acute sleep restriction heavily influences cognitive function, affecting executive processes such as attention, response inhibition, and memory. Previous neuroimaging studies have suggested a link between hippocampal activity and short-term memory function. However, the specific contribution of the hippocampus to the decline of short-term memory following sleep restriction has yet to be established. In the current study, we utilized resting-state functional magnetic resonance imaging (fMRI) to examine the association between hippocampal functional connectivity (FC) and the decline of short-term memory following total sleep deprivation (TSD). Twenty healthy adult males aged 20.9 ± 2.3 years (age range, 18-24 years) were enrolled in a within-subject crossover study. Short-term memory and FC were assessed using a Delay-matching short-term memory test and a resting-state fMRI scan before and after TSD. Seed-based correlation analysis was performed using fMRI data for the left and right hippocampus to identify differences in hippocampal FC following TSD. Subjects demonstrated reduced alertness and a decline in short-term memory performance following TSD. Moreover, fMRI analysis identified reduced hippocampal FC with the superior frontal gyrus (SFG), temporal regions, and supplementary motor area. In addition, an increase in FC between the hippocampus and bilateral thalamus was observed, the extent of which correlated with short-term memory performance following TSD. Our findings indicate that the disruption of hippocampal-cortical connectivity is linked to the decline in short-term memory observed after acute sleep restriction. Such results provide further evidence that support the cognitive impairment model of sleep deprivation.

    Rationale: Short-term exposure to ambient air pollution has been associated with lower lung function. Few studies have examined whether these associations are detectable at relatively low levels of pollution within current U.S. Environmental Protection Agency (EPA) standards. Objectives: To examine exposure to ambient air pollutants within EPA standards and lung function in a large cohort study. Methods: We included 3,262 participants of the Framingham Offspring and Third Generation cohorts living within 40 km of the Harvard Supersite monitor in Boston, Massachusetts (5,358 examinations, 1995–2011) who were not current smokers, with previous-day pollutant levels in compliance with EPA standards. We compared lung function (FEV1 and FVC) after previous-day exposure to particulate matter less than 2.5 μm in diameter (PM2.5), nitrogen dioxide (NO2), and ozone (O3) in the “moderate” range of the EPA Air Quality Index to exposure in the “good” range. We also examined linear relationships between moving averages of pollutant concentrations 1, 2, 3, 5, and 7 days before spirometry and lung function. Measurements and Main Results: Exposure to pollutant concentrations in the “moderate” range of the EPA Air Quality Index was associated with a 20.1-ml lower FEV1 for PM2.5 (95% confidence interval [CI], −33.4, −6.9), a 30.6-ml lower FEV1 for NO2 (95% CI, −60.9, −0.2), and a 55.7-ml lower FEV1 for O3 (95% CI, −100.7, −10.8) compared with the “good” range. The 1- and 2-day moving averages of PM2.5, NO2, and O3 before testing were negatively associated with FEV1 and FVC. Conclusions: Short-term exposure to PM2.5, NO2, and O3 within current EPA standards was associated with lower lung function in this cohort of adults. PMID:24200465

    Neuroplastic changes induced by sensory learning have been recognized within the cortices of specific modalities as well as within higher ordered multimodal areas. The interplay between these areas is not fully understood, particularly in the case of somatosensory learning. Here we examined functional and structural changes induced by short-term tactile training based of Braille reading, a task that requires both significant tactile expertise and mapping of tactile input onto multimodal representations. Subjects with normal vision were trained for 3 weeks to read Braille exclusively by touch and scanned before and after training, while performing a same-different discrimination task on Braille characters and meaningless characters. Functional and diffusion-weighted magnetic resonance imaging sequences were used to assess resulting changes. The strongest training-induced effect was found in the primary somatosensory cortex (SI), where we observed bilateral augmentation in activity accompanied by an increase in fractional anisotropy (FA) within the contralateral SI. Increases of white matter fractional anisotropy were also observed in the secondary somatosensory area (SII) and the thalamus. Outside of somatosensory system, changes in both structure and function were found in i.e., the fusiform gyrus, the medial frontal gyri and the inferior parietal lobule. Our results provide evidence for functional remodeling of the somatosensory pathway and higher ordered multimodal brain areas occurring as a result of short-lasting tactile learning, and add to them a novel picture of extensive white matter plasticity.

    Remembering complex events requires binding features within unified objects (conjunctions) and holding associations between objects (relations). Recent studies suggest that the two functions dissociate in long-term memory (LTM). Less is known about their functional organization in short-term memory (STM). The present study investigated this issue in patient AE affected by a stroke which caused damage to brain regions known to be relevant for relational functions both in LTM and in STM (i.e., the hippocampus). The assessment involved a battery of standard neuropsychological tasks and STM binding tasks. One STM binding task (Experiment 1) presented common objects and common colors forming either pairs (relations) or integrated objects (conjunctions). Free recall of relations or conjunctions was assessed. A second STM binding task used random polygons and non-primary colors instead (Experiment 2). Memory was assessed by selecting the features that made up the relations or the conjunctions from a set of single polygons and a set of single colors. The neuropsychological assessment revealed impaired delayed memory in AE. AE's pronounced relational STM binding deficits contrasted with his completely preserved conjunctive binding functions in both Experiments 1 and 2. Only 2.35% and 1.14% of the population were expected to have a discrepancy more extreme than that presented by AE in Experiments 1 and 2, respectively. Processing relations and conjunctions of very elementary nonspatial features in STM led to dissociating performances in AE. These findings may inform current theories of memory decline such as those linked to cognitive aging.

    Full Text Available Background: The transosseous-equivalent cross bridge double row (TESBDR rotator cuff (RC repair technique has been developed to optimize healing biology at a repaired RC tendon insertion. It has been shown in the laboratory to improve pressurized contact area and mean foot print pressure when compared with a double row anchor technique. Pressure has been shown to influence healing between tendon and bone, and the tendon compression vector provided by the transosseous-equivalent suture bridges may enhance healing. The purpose was to prospectively evaluate the outcomes of arthroscopic TESBDR RC repair. Methods: Single center prospective case series study. Sixty-nine patients were selected to undergo arthroscopic TESBDR RC repair and were included in the current study. Primary outcome measures included the Oxford Shoulder Score (OSS, the University of California, Los Angeles (UCLA score, the Constant-Murley (CM Score and Range of motion (ROM. Secondary outcome measures included a Visual Analogue Scale (VAS for pain, another VAS for patient satisfaction from the operative procedure, EuroQoL 5-Dimensions Questionnaire (EQ-5D for quality of life assessment. Results: At 24 months post-operative, average OSS score was 44, average UCLA score was 31, average CM score was 88, average forward flexion was 145°, average internal rotation was 35°, average external rotation was 79°, average abduction was 150°, average EQ-5D score was 0.73, average VAS for pain was 2.3, and average VAS for patient satisfaction was 9.2. Conclusion: Arthroscopic TESBDR RC repair is a procedure with good post-operative functional outcome and low re-tear rate based on a short term follow-up.

    Visual short-term memory binding tasks are a promising early marker for Alzheimer’s disease (AD). To uncover functional deficits of AD in these tasks it is meaningful to first study unimpaired brain function. Electroencephalogram recordings were obtained from encoding and maintenance periods of tasks performed by healthy young volunteers. We probe the task’s transient physiological underpinnings by contrasting shape only (Shape) and shape-colour binding (Bind) conditions, displayed in the left and right sides of the screen, separately. Particularly, we introduce and implement a novel technique named Modular Dirichlet Energy (MDE) which allows robust and flexible analysis of the functional network with unprecedented temporal precision. We find that connectivity in the Bind condition is less integrated with the global network than in the Shape condition in occipital and frontal modules during the encoding period of the right screen condition. Using MDE we are able to discern driving effects in the occipital module between 100-140 ms, coinciding with the P100 visually evoked potential, followed by a driving effect in the frontal module between 140-180 ms, suggesting that the differences found constitute an information processing difference between these modules. This provides temporally precise information over a heterogeneous population in promising tasks for the detection of AD.

    Because of widespread irregular lunch consumption by both children and adults, information on the effects of lunch on short-term cognitive functioning is relevant to public health. In September 2012, a MEDLINE search was conducted for studies in which the effects of lunch on cognitive performance were examined. Eleven experimental studies published from 1981 to 1996 were found and evaluated; all involved adults. In three studies, the effects of lunch and lunch skipping were compared; the remaining studies involved a determination of the effects of lunch size and lunch composition. Results of studies in which lunch was compared with no lunch indicate that lunch leads to potential impairment of some aspects of cognitive functioning in the early afternoon. Lunch size may influence cognitive functioning, with impairment more likely to occur after a large lunch than a small lunch. Furthermore, in comparison with low-fat lunches, high-fat lunches seem to result in slower but more accurate responses to some cognitive tasks. However, these suggestions must be viewed with caution, as they are based on only a few studies and are not thoroughly supported by high-quality evidence. In addition, results obtained with adults are not applicable to children. Thus, the potential effects of lunch need further examination in children and adults.

    Preterm prelabour rupture of the foetal membranes (pPROM) is the most common antecedent of preterm birth and can lead to death, neonatal disease and long-term disability. Previous small trials of antibiotics for pPROM suggested some health benefits for the neonate, but the results were inconclusive. A large, randomized, multicentre trial was undertaken to try to resolve this issue. In total, 4826 women with pPROM were randomized to one of four treatments: 325 mg co-amoxiclav plus 250 mg erythromycin, co-amoxiclav plus erythromycin placebo, erythromycin plus co-amoxiclav placebo, or co-amoxiclav placebo plus erythromycin placebo, four times daily for 10 d or until delivery. The primary outcome measure was a composite of neonatal death, chronic lung disease or major cerebral abnormality on ultrasonography before discharge from hospital. The analysis was undertaken by intention to treat. Indications of short-term respiratory function, chronic lung disease and major neonatal cerebral abnormality were reduced with the prescription of erythromycin. In contrast, the use of co-amoxiclav was associated with a significant increase in the occurrence of neonatal necrotizing enterocolitis. Prophylactic antibiotics can play a role in preterm prelabour rupture of the membranes in reducing infant morbidity.

    Our primary aim was to determine the short-term effects of a ketogenic diet on cardiac ventricular function in patients with refractory epilepsy. Thirty-eight drug-resistant epileptic patients who were treated with a ketogenic diet were enrolled in this prospective study. Echocardiography was performed on all patients before beginning the ketogenic diet and after the sixth month of therapy. Two-dimensional, M-mode, color flow, spectral Doppler, and pulsed-wave tissue Doppler imaging measurements were performed on all patients. The median age of the 32 patients was 45.5 months, and 22 (57.8%) of them were male. Body weight, height, and body mass index increased significantly at the sixth month of therapy when compared with baseline values (P 0.05). Doppler flow indices of mitral annulus and tricuspid annulus velocity of patients at baseline and month 6 showed no significant differences (P > 0.05). Tricuspid annular E/A ratio was lower at month 6 (P 0.05), there was a decrease in Ea velocity and Ea/Aa ratio gathered from tricuspid annulus at month 6 compared with baseline (P ketogenic diet does not impair left ventricular functions in children with refractory epilepsy; however, it may be associated with a right ventricular diastolic dysfunction.

    The rectum remains a predominant subsite of colorectal cancer in the Indian population. Unique to the Indian setting are significant social repercussions associated with a permanent stoma. On account of this, many patients who are advised abdominal perineal excision of the rectum (APER) default treatment. Accurate demonstration of the intersphincteric plane with magnetic resonance imaging has made intersphincteric resection (ISR) a viable option. This study is aimed at determining the feasibility and oncological adequacy of ISR in the Indian scenario. All patients with low rectal cancer who underwent an ISR at the Tata Memorial Centre, from July 2013 to December 2013 were included. Patients with invasion of the external sphincter and suboptimal preoperative sphincter function were excluded. Following standard preoperative staging, patients with a threatened circumferential resection margin (CRM) and/or mesorectal nodes were given preoperative chemoradiotherapy. The oncological adequacy of the procedure was evaluated in terms of margin positivity (distal and CRMs) and lymph node yield. Short-term perioperative outcomes included 30-day mortality, postoperative morbidity, anastomotic leaks, and length of hospital stay. Thirty-three patients with low rectal cancer and a median age of 38 years underwent ISR during the defined study period. Twenty-three patients (70 %) underwent open surgery whereas ten patients received a laparoscopic resection. The median blood loss and hospital stay was 300 mL and 7 days, respectively. Two patients had an involved CRM, but all distal margins were free of tumor. The quality of total mesorectal excision was satisfactory in all patients with a median lymph node yield of 9 nodes. Intersphincteric resection is feasible and oncologically safe in selected patients with low rectal cancer. Long-term functional and oncological outcomes are essential before it can be considered a viable alternative to APER.

    The aim of this study was to evaluate the perioperative and short-term results in a cohort of patients treated during the last year at our institution with the stent-assisted balloon-induced intimal disruption and relamination in aortic dissection repair (STABILISE) technique for acute complicated aortic dissection. Between June 2016 and June 2017, 10 patients (all male; mean age, 62.6 ± 7.4 years) received treatment for acute complicated aortic dissection with the STABILISE technique. After a standard provisional extension to induce complete attachment procedure using the commercially available endovascular dissection system (Cook Medical, Bloomington, Ind), the distal stent graft area and the bare stent area were ballooned to completely exclude the thoracic false lumen (FL) and to obtain a single-channeled abdominal aorta. Computed tomography was routinely performed within the first postoperative week before discharge and then at 3 months, at 6 months, and yearly thereafter. The technical and clinical success rates were analyzed. The 30-day technical and clinical success rates were 100%, with complete thrombosis of the thoracic FL and no type I endoleak. Malperfusion was resolved in all cases. No aortic ruptures were recorded, and no open conversion was required. One case of delayed spinal cord ischemia fully resolved within the discharge period. Predischarge computed tomography showed complete thrombosis of the thoracic FL in all cases. In two cases, some degree of patency of the abdominal FL was observed. At short-term follow-up, the overall aortic diameters remained stable with no further dilation.

    The aim of this study was to compare the short-term effects of Mobilization with movement (MWM) and Kinesiotaping (KT) on patients with patellofemoral pain (PFP) respect to pain, function and balance. Thirty-five female patients diagnosed with unilateral PFP were assigned into 2 groups. The first group (n = 18) received two techniques of MWM intervention (Straight Leg-Raise with Traction and Tibial Gliding) while KT was applied to the other group (n = 17). Both groups received 4 sessions of treatment twice a week for a period of 2 weeks with a 6-week-home exercise program. Pain severity, knee range of motion, hamstring flexibility, and physical performance (10-step stair climbing test, timed up and go test), Kujala Patellofemoral Pain Scoring and Y-Balance test were assessed. These outcomes were evaluated before the treatment, 45 min after the initial treatment, at the end of the 4-session-treatment during 2-week period and 6 weeks later in both groups. Both treatment groups had statistically significant improvements on pain, function and balance (p < 0.05). Pain at rest (p = 0.008) and the hamstring muscle flexibility (p = 0.027) were demonstrated significant improvements in favor of MWM group. Our results demonstrated similar results for both treatment techniques in terms of pain, function and balance. The MWM technique with exercise had a short-term favorable effect on pain at rest and hamstring muscle flexibility than the KT technique with exercise in patients with PFP.

    Hammertoe deformities are the most common lesser toe deformity. To date, no studies have looked at outcomes of operative management in the geriatric population, which may be at greater risk for complications or functional compromise because of comorbidities. Data on 58 patients undergoing operative correction of hammertoe deformities were prospectively collected. Clinical outcomes were assessed using preoperative and postoperative visual analogue scale (VAS) and Short Form Health Survey (SF-36) scores with a minimum of 6-month follow-up. Patients were divided into 2 groups on the basis of age at the time of surgery: younger than 65 and 65 and older. Complication rates and mean VAS and SF-36 improvement were compared. Forty-seven patients met inclusion criteria (7 men, 40 women), with 26 patients (37 toes) in the younger cohort and 21 patients (39 toes) in the older cohort. Overall, patients demonstrated significant improvement from baseline to 6 and 12 months postoperatively in VAS ( P < .001 and P < .001) and SF-36 ( P < .001 and P < .001) scores. Mean improvement in VAS and SF-36 scores was not significantly different between the groups at 6 and 12 months postoperatively. Complications occurred in 13.5% and 10.3% of patients in the younger and older cohorts, respectively. Outcomes of operative correction of hammertoe deformities in older patients were similar to outcomes in younger patients after greater than 6 months of follow-up. Overall improvement in VAS and SF-36 was statistically significant for both cohorts. There was no associated increase in complications for older patients. Level, III comparative series.

    Patient-reported experience is often used as a measure for quality of care, but no reports on patient satisfaction after cranial neurosurgery exist. To study the association of overall patient satisfaction and surgical outcome and to evaluate the applicability of overall patient satisfaction as a proxy for quality of care in elective cranial neurosurgery. We conducted an observational study on the relationship of overall patient satisfaction at 30 postoperative days with surgical and functional outcome (modified Rankin Scale [mRS] score) in a prospective, consecutive, and unselected cohort of 418 adult elective craniotomy patients enrolled between December 2011 and December 2012 at Helsinki University Hospital, Helsinki, Finland. Postoperative overall (subjective and objective) morbidity was present in 194 (46.4%) patients; yet almost 94% of all study patients reported high overall satisfaction. Low overall patient satisfaction at 30 days was not associated with postoperative major morbidity in elective cranial neurosurgery. Dependent functional status (mRS score ≥3) at 30 days, minor infections, poor postoperative subjective overall health status, and patient-reported severe symptoms (double vision, poor balance) may contribute to unsatisfactory patient experience. Overall patient satisfaction with elective cranial neurosurgery is high. Even 9 of 10 patients with postoperative major morbidity rated high overall patient satisfaction at 30 days. Overall patient satisfaction may merely reflect patient experience and subjective postoperative health status, and therefore it is a poor proxy for quality of care in elective cranial neurosurgery.

    There are limited screening tools to predict adverse postoperative outcomes for the geriatric surgical fracture population. Frailty is increasingly recognized as a risk assessment to capture complexity. The goal of this study was to use a short screening tool, the FRAIL scale, to categorize the level of frailty of older adults admitted with a fracture to determine the association of each frailty category with postoperative and 30-day outcomes. Retrospective cohort study. Level 1 trauma center. A total of 175 consecutive patients over age 70 years admitted to co-managed orthopedic trauma and geriatrics services. The FRAIL scale (short 5-question assessment of fatigue, resistance, aerobic capacity, illnesses, and loss of weight) classified the patients into 3 categories: robust (score = 0), prefrail (score = 1-2), and frail (score = 3-5). Postoperative outcome variables collected were postoperative complications, unplanned intensive care unit admission, length of stay (LOS), discharge disposition, and orthopedic follow-up after surgery. Thirty-day outcomes measured were 30-day readmission and 30-day mortality. Analysis of variance (1-way) and Kruskal-Wallis tests were used to compare continuous variables across the 3 FRAIL categories. Fisher exact tests were used to compare categorical variables. Multiple regression analysis, adjusted by age, sex, and Charlson index, was conducted to study the association between frailty category and outcomes. FRAIL scale categorized the patients into 3 groups: robust (n = 29), prefrail (n = 73), and frail (n = 73). There were statistically significant differences between groups in terms of age, comorbidity, dementia, functional dependency, polypharmacy, and rate of institutionalization, being higher in the frailest patients. Hip fracture was the most frequent fracture, and it was more frequent as the frailty of the patient increased (48%, 61%, and 75% in robust, prefrail, and frail groups, respectively). The American

    A short-term protocol for evaluation of National Football League (NFL) athletes incurring concussion has yet to be fully defined and framed in the context of the short-term potential team and career longevity, financial risk, and performance. To compare the short-term career outcomes for NFL players with concussions by analyzing the effect of concussions on (1) franchise release rate, (2) career length, (3) salary, and (4) performance. Cohort study; Level of evidence, 3. NFL player transaction records and publicly available injury reports from August 2005 to January 2016 were analyzed. All players sustaining documented concussions were evaluated for a change to inactive or DNP ("did not participate") status. A case-control design compared franchise release rates and remaining NFL career span. Career length was analyzed via survival analysis. Salary and performance differences were analyzed with publicly available contract data and a performance-scoring algorithm based on position/player level. Of the 5894 eligible NFL players over the 11-year period, 307 sustained publicly reported concussions resulting in the DNP injury protocol. Analysis of the probability of remaining in the league demonstrated a statistically significantly shorter career length for the concussion group at 3 and 5 years after concussion. The year-over-year change in contract value for the concussion group resulted in a mean overall salary reduction of $300,000 ± $1,300,000 per year (interquartile range, -$723,000 to $450,000 per year). The performance score reduction for all offensive scoring players sustaining concussions was statistically significant. This retrospective study demonstrated that NFL players who sustain a concussion face a higher overall franchise release rate and shorter career span. Players who sustained concussions may incur significant salary reductions and perform worse after concussion. Short-term reductions in longevity, performance, and salary after concussion exist and

    Full Text Available Objectives: Helicobacter pylori (H.pylori infection is major etiologic factor of chronic active gastritis and peptic ulcer disease. Functional dyspepsia (FD is defined as “persistent or recurrent abdominal pain or discomfort centered in the upper abdomen in patient who has no definite structural or biochemical explanation of their symptoms. It is uncertain whether treatment of H.pylori infection relieves symptoms in patients with FD. We searched short term effects of H.pylori eradication for symptoms in patients with FD.Material and method: We enrolled patients with dyspeptic symptoms which were diagnosed FD and satisfied en-rollment criteria of trial. Endoscopic biopsy was taken from each patient during upper gastrointestinal endoscopy. H.pylori infected patients were assigned to seven days of treatment with 30 mgr of lansoprozole twice daily, 1000 mg of amoksisilin twice daily, and 500 mg levofloxacin once daily. Patients were assessed whether treatment was suc-cessful or not by 14C urea breathe test after 6-8 week. Also pretreatment and post treatment symptom scores were questioned.Results: There were 99 female and 68 male patients. After treatment 114 patients (68% was negative for H. pylori, 53 patients (32% remained positive. Mean of age and proportion of sex was similar in H.pylori (+ and (- groups. While 111 (97.4% of H.pylori (- patients’ symptom scores decreased, 38 (71.7% of H.pylori (+ patients’ scores de-creased. There was significant differences between two groups (p=0.001.Conclusion: Eradication of H.pylori relieves the symptoms of functional dyspepsia. New trials for long term effect of H.pylori eradication on symptoms must be conducted in future.

    Survival of very-low-birth-weight infants (VLBWI) depends on professional perinatal management that begins at delivery. Korean Neonatal Network data on neonatal resuscitation management and initial care of VLBWI of less than 33 weeks gestation born from January 2013 to June 2014 were reviewed to investigate the current practice of neonatal resuscitation in Korea. Antenatal data, perinatal data, and short-term morbidities were analyzed. Out of 2,132 neonates, 91.7% needed resuscitation at birth, chest compression was performed on only 104 infants (5.4%) and epinephrine was administered to 80 infants (4.1%). Infants who received cardiac compression and/or epinephrine administration at birth (DR-CPR) were significantly more acidotic (P CPR resulted in greater early mortality of less than 7 days (OR, 5.64; 95% CI 3.25-9.77) increased intraventricular hemorrhage ≥ grade 3 (OR, 2.71; 95% CI 1.57-4.68), periventricular leukomalacia (OR, 2.94; 95% CI 1.72-5.01), and necrotizing enterocolitis (OR, 2.12; 95% CI 1.15-3.91) compared with those infants who needed only PPV. Meticulous and aggressive management of infants who needed DR-CPR at birth and quality improvement of the delivery room management will result in reduced morbidities and early death for the vulnerable VLBWI.

    2008-01-01

    Purpose Assess the patient-reported time to recovery for quality of life outcomes: post-surgery sequelae, discomfort/pain, oral function, and daily activities following orthognathic surgery Methods 170 patients (age 14 to 53) were enrolled in a prospective study prior to orthognathic surgery. Each patient was given a 20 item Health-Related Quality of Life instrument (OSPostop) to be completed each post-surgery day (PSD) for 90 days. The instrument was designed to assess patients’ perception of recovery for 4 domains: post-surgery sequelae; discomfort/pain; oral function; and daily activities. Discomfort/pain was recorded with a 7-point Likert-type scale; all other items were measured on a 5-point Likert-type scale. Results Post-surgery sequelae, except swelling, resolved within the first week after surgery for over 75% of the subjects. Discomfort/pain and medication usage persisted for two to three weeks after surgery for most subjects. Return to usual activities, except for recreational activities, which took substantially longer, mirrored the resolution of discomfort/pain. Problems with oral function took the longest to resolve, approximately 6 to 8 weeks for the majority of subjects. Conclusions Comprehensive daily postoperative patient quality of life data provides the orthognathic surgeon with estimated recovery times in distinct domains. This information is vital in the provision of informed consent as well as pre-operative education of patients regarding peri-operative and post-operative expectations. Ultimately this data can be combined with individual risk factors to provide personalized consent and expectations as well as tailor peri-operative and post-operative management regimens.

    Verbal short-term memory (VSTM) is thought to play a critical role in language learning. It is indexed by the nonword repetition task where listeners are asked to repeat meaningless words like 'blonterstaping'. The present study investigated the effect on nonword repetition performance of differences in efficiency of functioning of some part of the neural architecture mediating VSTM. Hypotheses were stated within Baddeley and Hitch's (1974) multicomponent model of VSTM, with respect to regions of the brain known to be active during tasks tapping into VSTM. We were specifically interested in activations associated with the posterior planum temporale (Spt) which emerge during rehearsal since this region is hypothesized to be central to VTSM (Buchsbaum, Olsen, Koch, & Berman, 2005a). Participants performed a delayed reaction time task in the scanner which explicitly mimicked the three main stages of information-processing involved in VSTM (encoding, rehearsal, recall (here recognition)). The data for each stage were then convolved with scores from a separately measured nonword repetition task. Rather than observing a pattern of individual differences located to specific regions specialized for supporting VSTM, a dissociation in direction of correlation in overlapping regions of the brain was observed during encoding and recognition. Larger hemodynamic responses during encoding were associated with better nonword repetition, and vice versa during recognition. There was little evidence for a network of activations specialized for VSTM. Instead, the main correlations were observed in regions also known to be involved in long-term memory. It seems that individuals who are better at nonword repetition and hence at language learning, activate these regions more efficiently than poorer nonword-repeaters early after stimulus input. These observations are discussed with respect to various models proposed for explaining the phenomenon of VSTM. Crown Copyright © 2011

    Previous studies assessing outcomes following orthognathic surgery rely primarily on single-center/surgeon experience. In addition to issues of generalizability, these studies are limited in evaluating the effect of operative volume on patient outcomes. Orthognathic procedures were identified in the 1999 to 2011 Healthcare Cost and Utilization Project Nationwide Inpatient Sample. Outcomes included occurrence of any in-hospital complication, extended length of stay (>2 days), and increased costs (>$10,784). High-volume hospitals were defined as the 90th percentile of case volume or higher (>31 cases/year). Univariate and multivariate analyses were conducted to identify independent predictors of outcomes. Trend analyses were performed to assess changes in the annual rate of patients treated at high-volume hospitals over the study period. Among 101,692 orthognathic surgery patients, 19.6 percent underwent concurrent ancillary procedures (i.e., genioplasty, rhinoplasty, or septoplasty), and 37.6 percent underwent double-jaw surgery. Fifty-three percent were treated at high-volume hospitals. High-volume hospitals more often performed ancillary procedures (21.4 percent versus 17.4 percent; p surgery (41.3 percent versus 33.4 percent; p orthognathic cases nationwide are performed at a small number of high-volume hospitals. These hospitals discharge patients earlier, perform more complex procedures, and have fewer complications. Risk, III.

    2013-01-01

    Renewed interest in prisoner rehabilitation to improve postrelease outcomes occurred in the 1990s, as policy makers reacted to burgeoning prison populations with calls to facilitate community reintegration and reduce recidivism. In 2003, the Federal government funded grants to implement locally designed reentry programs. Adult programs in 12 states were studied to determine the effects of the reentry programs on multiple outcomes. A two-stage matching procedure was used to examine the effectiveness of 12 reentry programs for adult males. In the first stage, "intact group matching" was used to identify comparison populations that were similar to program participants. In the second stage, propensity score matching was used to adjust for remaining differences between groups. Propensity score weighted logistic regression was used to examine the impact of reentry program participation on multiple outcomes measured 3 months after release. The study population was 1,697 adult males released from prisons in 2004-2005. Data consisted of interview data gathered 30 days prior to release and approximately 3 months following release, supplemented by administrative data from state departments of correction and the National Crime Information Center. Results suggest programs increased in-prison service receipt and produced modest positive outcomes across multiple domains (employment, housing, and substance use) 3 months after release. Although program participants reported fewer crimes, differences in postrelease arrest and reincarceration were not statistically significant. Incomplete implementation and service receipt by comparison group members may have resulted in insufficient statistical power to identify stronger treatment effects.

    To evaluate ocular outcome in premature infants treated with intravitreal ranibizumab injections for retinopathy of prematurity (ROP) over a period of 3 years. An interventional case series. Premature infants with high-risk prethreshold or threshold ROP with plus disease received an off label monotherapy with intravitreal injections of ranibizumab. The primary outcome was treatment success defined as regression of neovascularisation (NV) and absence of recurrence. The secondary outcomes were ocular and systemic adverse events and visual acuity. Six eyes were included in the study and treated with intravitreal injections of ranibizumab. All showed complete resolution of NV after a single injection. The anti-angiogenic intravitreal injections allowed for continued normal vessel growth into the peripheral retina, without any signs of disease recurrence or progression during the follow up period. No ocular or systemic adverse effects were observed. Three years of follow up in a small series suggest that intravitreal ranibizumab injections for ROP result in apparently preserved ocular outcome. Further large scale studies are needed to address the long-term safety and efficacy.

    To evaluate the influence of short-term estriol administration (10 d) on the hypothalamus-pituitary function and gonadotropins secretion in patients affected by functional hypothalamic amenorrhea (FHA). Controlled clinical study on patients with FHA (n = 12) in a clinical research environment. Hormonal determinations and gonadotropin (luteinizing hormone [LH] and FSH) response to a gonadotropin-releasing hormone (GnRH) bolus (10 μg) at baseline condition and after 10 d of therapy with 2 mg/d of estriol per os. Measurements of plasma LH, FSH, prolactin, estradiol, androstenedione, 17α-hydroxyprogesterone, insulin, cortisol, thyroid-stimulating hormone, free triiodothyronine, and free thyroxine. After treatment, the FHA patients showed a statistically significant increase of both LH and FSH plasma levels and the significant increase of their responses to the GnRH bolus. Estriol short-term therapy modulates within 10 d of administration the neuroendocrine control of the hypothalamus-pituitary unit and induces the recovery of both gonadotropins synthesis and secretion in hypogonadotropic patients with FHA.

    Although simultaneous resection of primary colorectal cancer and synchronous liver metastases is reported to be safe and effective, the feasibility of a laparoscopic approach remains controversial. This study evaluated the safety, feasibility, and short-term outcomes of simultaneous laparoscopic surgery for primary colorectal cancer with synchronous liver metastases. From September 2008 to December 2013, 10 patients underwent simultaneous laparoscopic resection of primary colorectal cancer and synchronous liver metastases with curative intent at our institute. The median operative time was 452 minutes, and the median estimated blood loss was 245 mL. Median times to discharge from the hospital and adjuvant chemotherapy were 13.5 and 44 postoperative days, respectively. Negative resection margins were achieved in all cases, with no postoperative mortality or major morbidity. Simultaneous laparoscopic colectomy and hepatectomy for primary colorectal cancer with synchronous liver metastases appears feasible with low morbidity and favorable outcomes. PMID:25058762

    Plant functional traits underlie vegetation responses to environmental changes such as global warming, and consequently influence ecosystem processes. While most of the existing studies focus on the effect of warming only on species diversity and productivity, we further investigated (i) how the structure of community plant functional traits in temperate grasslands respond to experimental warming, and (ii) whether species and functional diversity contribute to a greater stability of grasslands, in terms of vegetation composition and productivity. Intact vegetation turves were extracted from temperate subalpine grassland (highland) in the Eastern Pyrenees and transplanted into a warm continental, experimental site in Lleida, in Western Catalonia (lowland). The impacts of simulated warming on plant production and diversity, functional trait structure, and vegetation compositional stability were assessed. We observed an increase in biomass and a reduction in species and functional diversity under short-term warming. The functional structure of the grassland communities changed significantly, in terms of functional diversity and community-weighted means (CWM) for several traits. Acquisitive and fast-growing species with higher SLA, early flowering, erect growth habit, and rhizomatous strategy became dominant in the lowland. Productivity was significantly positively related to species, and to a lower extent, functional diversity, but productivity and stability after warming were more dependent on trait composition (CWM) than on diversity. The turves with more acquisitive species before warming changed less in composition after warming. Results suggest that (i) the short-term warming can lead to the dominance of acquisitive fast growing species over conservative species, thus reducing species richness, and (ii) the functional traits structure in grassland communities had a greater influence on the productivity and stability of the community under short-term warming

    Full Text Available Plant functional traits underlie vegetation responses to environmental changes such as global warming, and consequently influence ecosystem processes. While most of the existing studies focus on the effect of warming only on species diversity and productivity, we further investigated (i how the structure of community plant functional traits in temperate grasslands respond to experimental warming, and (ii whether species and functional diversity contribute to a greater stability of grasslands, in terms of vegetation composition and productivity. Intact vegetation turves were extracted from temperate subalpine grassland (highland in the Eastern Pyrenees and transplanted into a warm continental, experimental site in Lleida, in Western Catalonia (lowland.

    Full Text Available Abstract Background Hyperhomocysteinemia is a potentially modifiable risk factor for stroke, and may have a negative impact on the course of ischaemic stroke. The role of hyperhomocysteinemia as it relates to stroke in Africans is still uncertain. The objective of this study was to determine the prevalence and short-term impact of hyperhomocysteinemia in Nigerians with acute ischaemic stroke. We hypothesized that Hcy levels are significantly higher than in normal controls, worsen stroke severity, and increase short-term case fatality rates following acute ischaemic stroke. Methods The study employed both a case-control and prospective follow-up design to study hospitalized adults with first – ever acute ischaemic stroke presenting within 48 hours of onset. Clinical histories, neurological evaluation (including National Institutes of Health Stroke Scale (NIHSS scores on admission were documented. Total plasma Hcy was determined on fasting samples drawn from controls and stroke cases (within 24 hours of hospitalization. Outcome at 4 weeks was assessed in stroke patients using the Glasgow Outcome Scale (GOS. Results We evaluated 155 persons (69 acute ischaemic stroke and 86 healthy controls. The mean age ± SD of the cases was 58.8 ± 9.8 years, comparable to that of controls which was 58.3 ± 9.9 years (T = 0.32; P = 0.75. The mean duration of stroke (SD prior to hospitalization was 43.5 ± 38.8 hours, and mean admission NIHSS score was 10.1 ± 7.7. Total fasting Hcy in stroke patients was 10.2 ± 4.6 umol/L and did not differ significantly from controls (10.1 ± 3.6 umol/L; P = 0.88. Hyperhomocysteinemia, defined by plasma Hcy levels > 90th percentile of controls (>14.2 umol/L in women and >14.6 umol/L in men, was present in 7 (10.1% stroke cases and 11 (12.8% controls (odds ratio 0.86, 95% confidence interval 0.31 – 2.39; P > 0.05.

    The euroSCORE II is a widely used pre-coronary artery bypass graft surgery (CAGS) risk score, but its predictive power lacks the specificity to predict outcomes in high-risk patients (surgery case mix, revascularisation techniques and related outcomes in recent years. We investigated the utility of Cardiac Magnetic Resonance Imaging (CMRI) in predicting immediate and six-week outcomes after CAGS. Fifty-two consecutive patients with high euroSCORE II (>16) and left ventricular (LV) dysfunction (magnetic resonance imaging parameters were assessed in patients who either had complications immediately post-surgery (n=35), six weeks post-surgery (n=20) or were uncomplicated. The average age of patients recruited was 69±5 years with high euroSCORE II (22±4) and low 2D-echocardiography LV ejection fraction (38%±2%). Cardiac magnetic resonance imaging results demonstrated that those with immediate complications had higher LV scar/infarct burden as a proportion of LV mass (17±3% vs 10±3%; p=0.04) with lower circumferential relaxation index (2.5±0.46 vs 2.8±0.56; p=0.05) compared to those with no complications. Early mortality from surgery was 17% (n=9) and was associated with lower RV stroke volume (55±12 vs 68±18; p=0.03) and higher LV infarct scar/burden (18±2% vs 10±2%, p=0.04). Cardiac magnetic resonance imaging showed patients with complications at six weeks post-surgery had higher LV scar/infarct burden (14.5±2% vs 6.8±2%, p=0.03) compared to those without complications. Cardiac magnetic resonance imaging preoperative LV and RV parameters are valuable in assessing the likelihood of successful outcomes from CAGS in high-risk patients with LV dysfunction.

    Transition from pediatric to adult care is a critical time for patients with congenital heart disease. Lapses in care can lead to poor outcomes, including increased mortality. Formal transition clinics have been implemented to improve success of transferring care from pediatric to adult providers; however, data regarding outcomes remain limited. We sought to evaluate outcomes of transfer within a dedicated transition clinic for young adult patients with congenital heart disease. We performed a retrospective analysis of all 73 patients seen in a dedicated young adult congenital heart disease transition clinic from January 2012 to December 2015 within a single academic institution that delivered pediatric and adult care at separate children's and adult hospitals, respectively. Demographic characteristics including congenital heart disease severity, gender, age, presence of comorbidities, presence of cardiac implantable electronic devices, and type of insurance were correlated to success of transfer. Rate of successful transfer was evaluated, and multivariate analysis was performed to determine which demographic variables were favorably associated with transfer. Thirty-nine percent of patients successfully transferred from pediatric to adult services during the study period. Severe congenital heart disease (OR 4.44, 95% CI 1.25-15.79, P = .02) and presence of a cardiac implantable electronic device (OR 4.93, 95% CI 1.18-20.58, P = .03) correlated with transfer. Trends favoring successful transfer with presence of comorbidities and private insurance were also noted. Despite a dedicated transition clinic, successful transfer rates remained relatively low though comparable to previously published rates. Severity of disease and presence of implantable devices correlated with successful transfer. Other obstacles to transfer remain and require combined efforts from pediatric and adult care systems, insurance carriers, and policy makers to improve transfer outcomes.

    Full Text Available Background: Despite recent improvement in coronary intervention, there are many controversies about it’s results in diabetic patients. The goal of this study is comparison of in hospital outcome of diabetics after coronary intervention with nondiabetics. Methods: In this study 115 diabetic and 115non diabetic patients who admitted for coronary intervention in our center during 1383&84 were entered in an analytic study of Cohort type. Datas about clinical, aniographic, procedural and post procedural (24hours characteristics were entered in each patient’s form. Independent T test,chi-square and Fisher’s exact test were used for analyzing datas. Results: The Diabetic Patients were most often older men, and they had higher angina class, more co-risk factors and lower ejection fractions. Diabetic’s lesions were longer and more located in proximal portion of vessels. But success rate, major complication (death, revascularization, Q Wave MI and CVA, and minor complications (coronary/peripheral arteries complication, pulmonary edema, ischemic ECG had no significant differences between two groups. Conclusion: Diabetes mellitus does not affect short outcomes of coronary intervention as an independent factor. So intervention could be done in these patients with considering favorable outcomes.

    Robotic system has been increasingly used in pancreatectomy. However, the effectiveness of this method remains uncertain. This study compared the surgical outcomes between robot-assisted laparoscopic distal pancreatectomy and conventional laparoscopic distal pancreatectomy. During a 15-year period, 35 patients underwent minimally invasive approach of distal pancreatectomy in our center. Seventeen of these patients had robot-assisted laparoscopic approach, and the remaining 18 had conventional laparoscopic approach. Their operative parameters and perioperative outcomes were analyzed retrospectively in a prospective database. The mean operating time in the robotic group (221.4 min) was significantly longer than that in the laparoscopic group (173.6 min) (P = 0.026). Both robotic and conventional laparoscopic groups presented no significant difference in spleen-preservation rate (52.9% vs. 38.9%) (P = 0.505), operative blood loss (100.3 ml vs. 268.3 ml) (P = 0.29), overall morbidity rate (47.1% vs. 38.9%) (P = 0.73), and post-operative hospital stay (11.4 days vs. 14.2 days) (P = 0.46). Both groups also showed no perioperative mortality. Similar outcomes were observed in robotic distal pancreatectomy and conventional laparoscopic approach. However, robotic approach tended to have the advantages of less blood loss and shorter hospital stay. Further studies are necessary to determine the clinical position of robotic distal pancreatectomy.

    Uric acid has neuroprotective properties in experimental and clinical studies of neurodegenerative disease. It is, however, associated with increased risk of stroke, yet, despite some inconsistent findings, increasing evidence suggests it may also be related to improved stroke outcomes. We have determined whether there is an effect of plasma uric acid on the short-term outcome of stroke patients in a general hospital setting using the modified Rankin Scale (mRS). We also investigated the relationship of uric acid with other clinical correlates. Plasma uric acid was determined in 108 acute ischemic stroke patients and their mRS scores measured. Patients with a poor outcome (mRS > 2) had significantly lower uric acid than those with a better outcome; this remained after correcting for the effect of sex on uric acid concentrations. There was no significant association with other epidemiological factors or with cognitive function determined by Mini-Mental State Examination. An association between uric acid and the cerebral circulation was also found in which lower uric acid occurs with posterior artery involvement. These findings demonstrate in a naturalistic cohort of patients the association of uric acid with short-term disability following ischemic stroke. They also raise the question of whether uric acid may influence the regional brain involvement in stroke.

    Esophageal resection in patients with esophageal cancer (EC) is still associated with high mortality and morbidity rates. We aimed to develop a simple preoperative risk score for the prediction of short-term and long-term outcomes for patients with EC treated by esophageal resection. In total, 498 patients suffering from esophageal carcinoma, who underwent esophageal resection, were included in this retrospective cohort study. Three preoperative esophagectomy risk (PER) groups were defined based on preoperative functional evaluation of different organ systems by validated tools (revised cardiac risk index, model for end-stage liver disease score, and pulmonary function test). Clinicopathological parameters, morbidity, and mortality as well as disease-free survival (DFS) and overall survival (OS) were correlated to the PER score. The PER score significantly predicted the short-term outcome of patients with EC who underwent esophageal resection. PER 2 and PER 3 patients had at least double the risk of morbidity and mortality compared to PER 1 patients. Furthermore, a higher PER score was associated with shorter DFS (P PER score was identified as an independent predictor of tumor recurrence (hazard ratio [HR] 2.1; P PER score allows preoperative objective allocation of patients with EC into different risk categories for morbidity, mortality, and long-term outcomes. Thus, multicenter studies are needed for independent validation of the PER score.

    To evaluate the serial changes in sexual function in the short-term period after holmium laser enucleation of the prostate (HoLEP) for benign prostatic hyperplasia (BPH) and to investigate whether a change in each domain of the International Index of Erectile Function (IIEF) is associated with improvement of micturition. Thirty-eight potent men who underwent HoLEP and in whom complete 12-month follow-up data on the IIEF were available were included in this retrospective study. All patients underwent a baseline evaluation for BPH. The surgical outcome was evaluated at 1, 3, 6, and 12 months postoperatively by use of the International Prostate Symptom Score, IIEF, and uroflowmetry. The mean age and body mass index of the patients was 64.5±6.2 years and 24.2±2.6 kg/m(2), respectively. Mean total prostate volume and transitional zone volume were 48.8±18.8 ml and 24.2±16.1 ml, respectively. Most IIEF domain scores showed a slight decrease at 1, 3, and 6 months after surgery but recovered to the baseline or showed a marginal but nonsignificant increase at 12 months postoperatively compared with baseline. Orgasmic function and the overall sexual satisfaction domain score remained slightly reduced up to 12 months postoperatively. There was no significant correlation between improvement of micturition and change in sexual function throughout the follow-up period after surgery. Although HoLEP achieves significant improvements in micturition, overall sexual function decreases slightly in the early postoperative period, but recovers to the baseline at 12 months postoperatively. Our data suggest that changes in sexual function after HoLEP are not associated with improvement of micturition.

    Full Text Available Purpose: This study aimed to evaluate the clinical outcomes and complications of transvaginal minimal mesh repair without using commercially available kits for treatment of pelvic organ prolapse (POP. Materials and Methods: This retrospective cohort study involved 91 women who underwent surgical management of POP with originally designed small mesh between July 2014 and August 2015. This mesh is 56% smaller than the mesh widely used in Japan, and it has only two arms delivered into each right and left sacrospinous ligament. The main study outcome was the anatomic cure rate defined as recurrence of POP quantification (POP-Q stage II or more. We also assessed changes in the overactive bladder symptom score (OABSS and prolapse quality of life questionnaire (P-QOL and evaluated adverse events. Finally, we compared patient backgrounds between the patients with and without recurrence. Results: Prolapse recurred in 10 of 91 patients (11.0%, and all patients with recurrence were diagnosed as POP-Q stage II. As adverse events, only mesh erosion occurred in two (2.2% and pelvic pain in one (1.1% of the 91 patients. The OABSS and P-QOL were significantly improved by the operation. When we compared patient backgrounds between the patients with and without recurrence, body mass index was the only factor influencing affecting recurrence. Conclusions: Transvaginal minimal mesh repair resulted in successful outcomes with low mesh-related complications and anatomic recurrence at one year. Furthermore, significant improvement in QOL was offered by this procedure. Our minimal mesh technique should be considered as one treatment option for the management of POP.

    Obesity and underweight are associated with a higher postlung transplantation (LTx) mortality. This study aims to assess the impact of the changes in body mass index (BMI) during the waiting period for LTx on early postoperative outcomes. Medical records of 502 consecutive cases of LTx performed at our institution between 1999 and 2015 were reviewed. Patients were stratified per change in BMI category between pre-LTx assessment (candidate BMI) and transplant BMI as follows: A-candidate BMI, less than 18.5 or 18.5 to 29.9 and transplant BMI, less than 18.5; B-candidate BMI, less than 18.5 and transplant BMI, 18.5 to 29.9; C-candidate BMI, 18.5 to 29.9 and transplant BMI, 18.5 to 29.9; D-candidate BMI, 30 or greater and transplant BMI, 18.5 to 29.9; and E-candidate BMI, 30 or greater or 18.5 to 29.9 and transplant BMI, 30 or greater. Our primary outcome was in-hospital mortality and secondary outcomes were length of mechanical ventilation, intensive care unit length of stay (LOS), hospital LOS and postoperative complications. BMI variation during the waiting time was common, as 1/3 of patients experienced a change in BMI category. Length of mechanical ventilation (21 days vs 9 days; P = 0.018), intensive care unit LOS (26 days vs 15 days; P = 0.035), and rates of surgical complications (76% vs 44%; P = 0.018) were significantly worse in patients of group E versus group D. Obese candidates who failed to decrease BMI less than 30 by transplant exhibited an increased risk of postoperative mortality (odds ratio, 2.62; 95% confidence interval, 1.01-6.48) compared with patients in group C. Pre-LTx BMI evolution had no impact on postoperative morbidity and mortality in underweight patients. Our results suggest that obese candidates with an unfavorable pretransplant BMI evolution are at greater risk of worse post-LTx outcomes.

    To investigate the predictive value of overgeneral memory (OGM) for outcome of electroconvulsive therapy (ECT) for depression. The Autobiographical Memory Test was used to measure OGM in 25 patients with depression before ECT. The Hamilton Rating Scale for Depression (HRSD) was administered weekly to 1 week posttreatment. Overgeneral memory did not predict HRSD scores from the last ECT treatment, but did predict HRSD change scores from the last treatment to 1-week follow-up: patients high in OGM experienced a relatively greater increase in HRSD scores after the last treatment. Results further extend the status of OGM as a predictor of an unfavorable course of depression to a previously unstudied ECT population.

Most arise as a complication of prostate cancer treatment. Several procedures have been described to repair rectourethral fistulas with varying outcomes. We review the etiology, management, and outcomes of patients with rectourethral fistulas at our institution.Materials and methods: A retrospective review of patients undergoing repair of rectourethral fistulas was undertaken. Data were collected on patient demographics, fistula etiology, operative procedure, fecal and urinary diversion, and clinical outcome. Patients with urinary and/or fecal diversion underwent radiographic evaluation to confirm closure of the fistula prior to reversal of the diversion.Results: Fistula repair was performed on 22 patients from 1999 to 2009. All the patients were male of an average age of 69 years (range: 39–82 years. All patients, except one, had prostate cancer. Fistula formation was associated with radiotherapy in 54.4% of patients, brachytherapy in 36.4% of patients, and with external beam radiation therapy in 18.2% of patients. Other causes included prostatectomy (seven patients, 31.8%, cryotherapy (two patients, 9.1%, and perianal abscess (one patient, 4.5%.

    Bacterial cholangitis (BC) is a common complication in patients with biliary atresia (BA) and is characterized by fever, acholic stools and positive blood cultures. The diagnosis is often empirical because the yield of blood cultures is low. It is difficult to differentiate BC from other febrile episodes. In order to characterize the clinical and laboratory features of BC in patients with BA, identify risk factors, and correlate cholangitis with outcome, 37 patients with BA from 1993 to 1998 who underwent a Kasai operation in our hospital were studied. The follow-up period ranged from 6 to 59 months. A total of 107 febrile episodes were documented in these patients. The diagnostic criteria for cholangitis were fever, increased jaundice, or acholic stools. The clinical features, laboratory data, results of bacterial cultures, and outcomes were analyzed retrospectively. A total of 107 febrile episodes, including 78 bouts of cholangitis and 29 non-cholangitis infections, were found in 34 patients. Patients with BC had higher postoperative bilirubin levels (P = 0.02) and less frequent use of prophylactic antibiotics (P = 0.05) than those with non-cholangitis infections. Abnormal white blood cell counts (> 12,000 or Acinetobacter baumanni, and Salmonella typhi. The sensitivity tests justified empirical therapy with ceftriaxone. The effectiveness of prophylactic trimethoprim-sulfamethoxazole or neomycin warrants further studies. BC was a highly prevalent postoperative complication in patients with BA, especially those with inadequate bile drainage. It significantly affected early mortality. Aggressive and complete treatment with empirical ceftriaxone was appropriate.

    The objectives of this study were to characterize 60-d outcomes after treatment of mild (abnormal milk) and moderate (abnormal milk and abnormal udder) cases of clinical mastitis (CM) occurring in a single quarter of cows on Wisconsin farms (n=4) and to determine risk factors associated with those outcomes. Duplicate milk samples were collected from the affected quarter of each cow for microbiological analysis at the onset of CM (PRE) and 21 d later (POST). Cows were treated only in the affected quarter using an intramammary product containing 125 mg of ceftiofur. Bacteriological cure was defined as absence of pathogens in the POST sample obtained from the enrolled quarter. Recurrence was defined for the cow when CM occurred after the milk-withholding period for the enrolled case of CM. Retention in the herd was defined when a cow was retained within the herd for the 60-d follow-up period. Somatic cell count reduction (SCCR) was defined at the cow level as somatic cell count (SCC) below 200,000 cells/mL at the Dairy Herd Improvement Association test day occurring between 21 to 55 d post-treatment. The effects of farm, days in milk, parity, severity, microbiological diagnosis at PRE, previous milk yield, previous SCC, previous occurrence of CM and treatment duration on selected post-treatment outcomes were assessed using Chi-squared analysis and logistic regression. Microbiological results at PRE were distributed as: Escherichia coli (n=14), Klebsiella spp. (n=11), Enterobacter spp. (n=8), Serratia spp. (n=7), other gram-negative species (n=3), Streptococcus spp. (n=25), coagulase-negative staphylococci (n=4); Staphylococcus aureus (n=1); Streptococcus agalactiae (n=1), other gram-positive species (n=9), and culture negative (n=60). Treated quarters were more likely to experience bacteriological cure when the cow experienced CM for the first time in the lactation and when no pathogen was recovered from PRE milk samples obtained from the enrolled quarter.

    Outcomes for oesophagogastric cancer surgery are compared with the aim of benchmarking quality of care. Adjusting for patient characteristics is crucial to avoid biased comparisons between providers. The study objective was to develop a case-mix adjustment model for comparing 30- and 90-day mortality and anastomotic leakage rates after oesophagogastric cancer resections. The study reviewed existing models, considered expert opinion and examined audit data in order to select predictors that were consequently used to develop a case-mix adjustment model for the National Oesophago-Gastric Cancer Audit, covering England and Wales. Models were developed on patients undergoing surgical resection between April 2011 and March 2013 using logistic regression. Model calibration and discrimination was quantified using a bootstrap procedure. Most existing risk models for oesophagogastric resections were methodologically weak, outdated or based on detailed laboratory data that are not generally available. In 4882 patients with oesophagogastric cancer used for model development, 30- and 90-day mortality rates were 2·3 and 4·4 per cent respectively, and 6·2 per cent of patients developed an anastomotic leak. The internally validated models, based on predictors selected from the literature, showed moderate discrimination (area under the receiver operating characteristic (ROC) curve 0·646 for 30-day mortality, 0·664 for 90-day mortality and 0·587 for anastomotic leakage) and good calibration. Based on available data, three case-mix adjustment models for postoperative outcomes in patients undergoing curative surgery for oesophagogastric cancer were developed. These models should be used for risk adjustment when assessing hospital performance in the National Health Service, and tested in other large health systems. © 2015 BJS Society Ltd Published by John Wiley & Sons Ltd.

    The predictive value of short-term arm pain relief after 'indirect' cervical epidural steroid injection (ESI) for the 1-month treatment response has been previously demonstrated. It remained to be answered whether the long-term response could be estimated by the early post-interventional pain course as well. Prospective observational study, following a cohort of n = 45 patients for a period of 24 months after 'indirect' ESI for radiculopathy secondary to a single-level cervical disk herniation (CDH). Arm and neck pain on the visual analog scale (VAS), health-related quality of life with the Short Form-12 (SF-12), and functional outcome with the Neck Pain and Disability (NPAD) Scale were assessed. Any additional invasive treatment after a single injection (second injection or surgery) defined treatment outcome as 'non-response'. At 24 months, n = 30 (66.7%) patients were responders and n = 15 (33.3%) were non-responders. Non-responders exited the follow-up at 1 month (n = 10), at 3 months (n = 4), and at 6 months (n = 1). No patients were injected again or operated on between the 6- and 24-month follow-up. Patients with favorable treatment response at 24 months had significantly lower VAS arm pain (p  50% short term pain reduction was not a reliable predictor of the 24-month responder status. SF-12 and NPAD scores were better among treatment responders in the long term. Patients who require a second injection or surgery after 'indirect' cervical ESI for a symptomatic CDH do so within the first 6 months. Short-term pain relief cannot reliably predict the long-term outcome.

    To clarify the feasibility and utility of reduced port surgery (RPS) for achalasia. Between September 2005 and June 2013, 359 patients with esophageal achalasia, excluding cases of reoperation, underwent laparoscopic Heller myotomy and Dor fundoplication (LHD) according to our clinical pathway. Three-hundred and twenty-seven patients underwent LHD with five incisions (conventional approach), while the other 32 patients underwent RPS, including eight via SILS. The clinical data were collected in a prospective fashion and retrospectively reviewed. We selected 24 patients matched for gender, age and morphologic type with patients in the RPS group from among the 327 patients (C group). The surgical outcomes were compared between the C and RPS groups. There were no significant differences between the two groups in the duration of symptoms, dysphagia score, chest pain score, shape of the distal esophagus and esophageal clearance. The operative time was significantly longer in the RPS group than in the C group (p achalasia are comparable to those obtained with the conventional method.

    The aim of this was to assess clinical features and outcome in pediatric-onset Takayasu's arteritis (TA). Retrospective data analysis of patients diagnosed with TA over last 13 years with onset before 18 years of age was done. Their presenting features, activity (by NIH criteria, ITAS2010, ITAS-A), disease extent (by DEI.Tak) and angiographic findings were retrieved from clinic files. Treatment received and follow-up data on disease activity and damage by TA damage score (TADS) were also analyzed. Wherever repeated angiography data were available, the same was analyzed. Values are expressed as median with interquartile range in brackets. There were 29 patients (19 females) with median age at diagnosis of 14 (13-16) years and delay to diagnosis of 1 (0.4-2) year. Common presenting symptoms were pulse loss (23/29) and hypertension (22/29). Patients had extensive disease at presentation with median DEI.Tak of 12 (9.5-15); 23/29 had elevated acute-phase reactants, and 28/29 were active at presentation [median ITAS2010 13 (8-15.5), ITAS-A 14 (10-17)]. Numano's type V was the commonest angiographic type (22/29). At a median follow-up of 2.4 (1.5-5.1) years, 2/20 were active whereas all had sustained damage despite a majority (17/20) being on immunosuppression. The median TADS was 8 (6.3-9.8) with pulse loss, claudication and hypertension being the commonest damage item. Two needed renal artery stenting to control hypertension. Angiographic assessment at least 2 years apart demonstrated disease progression in 5 of 6 patients despite immunosuppression. Significant damage accrued on follow-up despite immunosuppression and control of disease activity. Hypertension remains the major long-term morbidity.

    Acute heart failure (AHF) is one of the most frequently encountered cardiovascular conditions that can seriously affect the patient's prognosis. However, the importance of early triage and treatment initiation in the setting of AHF has not been recognized. The Tokyo Cardiac Care Unit Network Database prospectively collected information of emergency admissions to acute cardiac care facilities in 2005-2007 from 67 participating hospitals in the Tokyo metropolitan area. We analyzed records of 1,218 AHF patients transported to medical centers via emergency medical services (EMS). AHF was defined as rapid onset or change in the signs and symptoms of heart failure, resulting in the need for urgent therapy. Patients with acute coronary syndrome were excluded from this analysis. Logistic regression analysis was performed to calculate the risk-adjusted in-hospital mortality. A majority of the patients were elderly (76.1 ± 11.5 years old) and male (54.1%). The overall in-hospital mortality rate was 6.0%. The median time interval between symptom onset and EMS arrival (response time) was 64 minutes (interquartile range [IQR] 26-205 minutes), and that between EMS arrival and ER arrival (transportation time) was 27 minutes (IQR 9-78 minutes). The risk-adjusted mortality increased with transportation time, but did not correlate with the response time. Those who took >45 minutes to arrive at the medical centers were at a higher risk for in-hospital mortality (odds ratio 2.24, 95% confidence interval 1.17-4.31; P = .015). Transportation time correlated with risk-adjusted mortality, and steps should be taken to reduce the EMS transfer time to improve the outcome in AHF patients. Copyright © 2011 Elsevier Inc.

    Full Text Available Abstract Background Laparoscopically-assisted right hemicolectomy (LRH is an acceptable alternative to open surgery for right-sided colon cancer which offers patients less pain and faster recovery. However, special equipment and substantial surgical experience are required. The aim of the study is to compare the short-term surgical outcomes of LRH and open right hemicolectomy through right transverse skin crease incision (ORHT for right-sided colon cancer. Patients and methods This retrospective study included 33 patients with right-sided colon cancer who underwent elective right hemicolectomy by laparoscopic or open approaches through right transverse skin crease incision between March 2004 and September 2006 at the Department of Surgery, Faculty of Medicine Siriraj Hospital. Operative details, postoperative requirement of narcotics, recovery of bowel function, and oncological parameters were analyzed. Results Thirteen patients underwent LRH and 20 patients underwent ORHT. Both approaches achieved adequate oncological resection of the tumor. The laparoscopic group were characterized by shorter average incision lengths (7.7 vs 10.3 cm; p Conclusion LRH and ORHT for right-sided colon cancer resulted in the same short-term surgical outcomes including postoperative bowel function, narcotics consumption and length of hospital stay. However, LRH required a significantly longer operating time.

Furthermore, OM seems to require longer time to recover and regain rapid muscle force capacity, which may lead to a larger risk of falling in aged individuals after periods of short-term disuse.......Very little attention has been given to the combined effects of aging and disuse as separate factors causing deterioration in muscle mechanical function. Thus the purpose of this study was to investigate the effects of 2 wk of immobilization followed by 4 wk of retraining on knee extensor muscle...... mechanical function (e.g., maximal strength and rapid force capacity) and muscle fiber morphology in 9 old (OM: 67.3 ± 1.3 yr) and 11 young healthy men (YM: 24.4 ± 0.5 yr) with comparable levels of physical activity.

    To investigate the short-term psychological function of opiate addicts who have undergone ablative stereotactic surgery targeting the nucleus accumbens (NAc) for alleviating opiate drug psychological dependence. The psychological functional status of 14 opiate addicts was assessed by standardized psychological tests both before and approximately 3 months after stereotactic surgery. Standardized tests included the Wechsler Adult Intelligence Scale-Revised Chinese (WAIS-RC), the Clinical Memory Scale of Chinese (CMS), the Eysenck Personality Questionnaire (EPQ) and the Symptom Checklist 90 (SCL-90). The evaluation of psychological dimensions included intelligence, memory, personality characteristics and mental health symptoms. Compared with the preoperative state, there was no statistically significant difference in full-scale intelligence quotient (IQ) postoperatively, but without Bonferroni correction a significant decline by 13.55% (p memory quotient (MQ) of CMS demonstrated a significant decline of 10.65% (p increase (p intelligence measures were not changed significantly, their short-term memory and attention appeared to decline postoperatively. In addition, there was a trend towards change in some personality characteristics postoperatively. The postoperative mental health levels of the patients increased, indicating a trend towards improvement. Stereotactic ablation of the NAc in opiate addicts may be associated with short-term negative psychological functions. Advisement regarding the safety of the new surgical modality and recommendations for further investigation are necessary. Copyright 2008 S. Karger AG, Basel.

    Objective: to investigate the risk factors of short-term poor outcome among patients suffering from acute cerebral infarction who had different subtypes of cerebral infarction. Methods: A total of 3231 acute cerebral infarction patients were included in the present study. Data on demographic characteristics, life style, risk factors, history of cardiovascular disease, admission blood pressure, and clinical outcome at discharge were collected for all participants. Poor outcome was defined as NIHSS ≥10 at discharge or death occurring during hospitalization. The association between poor outcome of cerebral infarction and risk factors was analyzed by using multiple logistic models. Results: Incidence rate of poor outcome is the highest in the patients with cerebral embolism, next in patients with cerebral thrombosis and the lowest in patients with lacunar infarction. Cerebral thrombosis was positively associated with smoking (OR: 1.228; 95% CI: 1.013∼1.637), dyslipidemia (OR: 1.264; 95% CI: 1.081∼1.478), and a history of diabetes mellitus (OR: 1.371; 95% CI: 1.075∼1.747); cerebral embolism was positively associated with a history of atrial fibrillation (OR: 3.131; 95% CI: 1.206∼8.128) and a history of rheumatic heart disease (OR: 5.601; 95% CI: 1.561∼20.091); lacunar infarction is positively associated with alcohol consumption, (OR: 1.428; 95% CI: 1.063∼1.919). Conclusion: The incidence rate of poor outcome is the highest in the patients with cerebral embolism among three subtypes of cerebral infarction, there are different risk factors of poor outcome for three subtypes of cerebral infarction.

  9. Short-term memory of motor network performance via activity-dependent potentiation of Na+/K+ pump function.

    2012-03-20

    Brain networks memorize previous performance to adjust their output in light of past experience. These activity-dependent modifications generally result from changes in synaptic strengths or ionic conductances, and ion pumps have only rarely been demonstrated to play a dynamic role. Locomotor behavior is produced by central pattern generator (CPG) networks and modified by sensory and descending signals to allow for changes in movement frequency, intensity, and duration, but whether or how the CPG networks recall recent activity is largely unknown. In Xenopus frog tadpoles, swim bout duration correlates linearly with interswim interval, suggesting that the locomotor network retains a short-term memory of previous output. We discovered an ultraslow, minute-long afterhyperpolarization (usAHP) in network neurons following locomotor episodes. The usAHP is mediated by an activity- and sodium spike-dependent enhancement of electrogenic Na(+)/K(+) pump function. By integrating spike frequency over time and linking the membrane potential of spinal neurons to network performance, the usAHP plays a dynamic role in short-term motor memory. Because Na(+)/K(+) pumps are ubiquitously expressed in neurons of all animals and because sodium spikes inevitably accompany network activity, the usAHP may represent a phylogenetically conserved but largely overlooked mechanism for short-term memory of neural network function.

    To determine the effect of clinical presentations of neck pain on short-term physical therapy outcomes. Retrospective analysis of pair-matched groups from a clinical cohort. Thirteen outpatient physical therapy clinics in 1 health care system. Patients (N=1069) grouped by common clinical presentations of neck pain: nonspecific neck pain (NSNP) with duration 4 weeks; neck pain with arm pain; neck pain with headache; and neck pain from whiplash. Conservative interventions provided by physical therapists. Neck Disability Index (NDI) and numerical pain rating scale (NPRS) recorded at the initial and last visits. The main outcome of interest was achieving recovery status on the NDI. Changes in NDI and NPRS were compared between clinical presentation groups. Compared with patients presenting with NSNP >4 weeks, patients with NSNP neck pain and arm pain demonstrated an increased odds of achieving recovery status on the NDI (P=.04) compared with patients presenting with NSNP >4 weeks. Treating patients with NSNP within <4 weeks of onset of symptoms may lead to improved clinical outcomes from physical therapy compared with other common clinical presentations.

    Short-term visual memory was studied by displaying arrays of four or five numerals, each numeral in its own depth plane, followed after various delays by an arrow cue shown in one of the depth planes. Subjects reported the numeral at the depth cued by the arrow. Accuracy fell with increasing cue delay for the first 500 ms or so, and then recovered almost fully. This dipping pattern contrasts with the usual iconic decay observed for memory traces. The dip occurred with or without a verbal or color-shape retention load on working memory. In contrast, accuracy did not change with delay when a tonal cue replaced the arrow cue. We hypothesized that information concerning the depths of the numerals decays over time in sensory memory, but that cued recall is aided later on by transfer to a visual memory specialized for depth. This transfer is sufficiently rapid with a tonal cue to compensate for the sensory decay, but it is slowed by the need to tag the arrow cue's depth relative to the depths of the numerals, exposing a dip when sensation has decayed and transfer is not yet complete. A model with a fixed rate of sensory decay and varied transfer rates across individuals captures the dip as well as the cue modality effect.

    Previous investigations of short-term outcomes after preoperative exposure to biological therapy in inflammatory bowel disease (IBD) were conflicting. The authors aimed to assess postoperative outcomes in patients who underwent abdominal surgery with recent exposure to anti-tumour necrosis factor therapy. A retrospective case-control study with detailed matching was performed for subjects with IBD with and without exposure to biologics within 180 days of abdominal surgery. Postoperative outcomes were compared between the groups. 473 procedures were reviewed consisting of 195 patients with exposure to biologics and 278 matched controls. There were no significant differences in most postoperative outcomes such as: length of stay, fever (≥ 38.5°C), urinary tract infection, pneumonia, bacteraemia, readmission, reoperations and mortality. On univariate analysis, procedures on biologics had more wound infections compared with controls (19% vs 11%; p=0.008), but this was not significant in multivariate analysis. Concomitant therapy with biologics and thiopurines was associated with increased frequencies of urinary tract infections (p=0.0007) and wound infections (p=0.0045). Operations performed ≤ 14 days from last biologic dose had similar rates of infections and other outcomes when compared with those performed within 15-30 days or 31-180 days. Patients with detectable preoperative infliximab levels had similar rates of wound infection compared with those with undetectable levels (3/10 vs 0/9; p=0.21). Preoperative treatment with TNF-α antagonists in patients with IBD is not associated with most early postoperative complications. A shorter time interval from last biological dose is not associated with increased postoperative complications. In most cases, surgery should not be delayed, and appropriate biological therapy may be continued perioperatively.

    Data about single-incision laparoscopic surgery (SILS) in locally advanced colorectal cancers are scarce. This study aimed to evaluate perioperative and shortterm oncologic outcomes of SILS in pT3-T4 colorectal cancer. From 2011 to 2015 data from 249 SILS performed in our Colorectal Unit were entered into a prospective database. Data regarding patients with a pT3-T4 colorectal adenocarcinoma were compared to those with pTis-pT2. Factors influencing conversion were assessed by multivariate analysis. There were 100 consecutive patients (T3-T4 = 70, Tis-T2 = 30). Demographics were similar. Tumor size was significantly larger in the T3-T4 group [3.9cm vs 2cm; p2) postoperative complication rate was similar between groups (8.6% vs 10% ; p = 0.999), as well as conversion rate (18.6% vs 6.7% ; p = 0.220). Finally, there were no differences in terms of hospital stay and mortality rate. On multivariate analysis, age (OR = 1.06, 95%CI: 1.012-1.113 ; p = 0.015] and stage IV (OR = 5.372, 95%CI: 1.320-21.862, p = 0.019) were independently associated with conversion. SILS for locally advanced colorectal cancer did not affect the short-term outcomes in this series and oncological clearance remained satisfactory. Age and stage IV disease are independent risk factors for conversion. © Acta Gastro-Enterologica Belgica.

    Full Text Available ObjectiveTo evaluate the clinical value of five-stage prognostic system in predicting the short-term outcome of patients with liver cirrhosis, and to compare it with the Child-Turcotte-Pugh (CTP and Model of End-Stage Liver Disease (MELD scores. MethodsTwo hundred and one hospitalized patients with liver cirrhosis in the Department of Gastroenterology in the First Affiliated Hospital of Anhui Medical University from January 2011 to January 2014 were enrolled in the study and followed up for at least six months. Patients were classified accorded to the five-stage prognostic system, and the mortality rate in each stage was measured. The receiver operating characteristic (ROC curve and the area under the ROC curve (AUC were used to assess the accuracy of the five-stage prognostic system in predicting the short-term death risk of cirrhotic patients, which was then compared with the CTP and MELD scores. Categorical data were analyzed by chi-square test. Comparison of AUC was made by normal distribution Z test. Spearman′s correlation analysis was used to investigate the correlation of the five-stage prognostic system with the CTP and MELD scores. ResultsThe study used the admission time as the starting point and the death of patients or study termination time as the endpoint. Among the 201 patients, 50 (24.9% died within six months. Based on the five-stage prognostic system, the mortality rates for stages 1 to 5 were 0(0/11, 0(0/18, 4.2%(2/48, 16.3% (7/43, and 50.6%(41/81, respectively. In patients with decompensated cirrhosis (stages 3, 4, and 5, the mortality increased with stage, and the differences in mortality between patients in stages 3 and 4, 3 and 5, and 4 and 5 were all significant (χ2=3.89, 35.33, and 13.96, respectively; P=0.049, 0.000, and 0.049, respectively. The AUC for the five-stage prognostic system, five-stage prognostic system combined with CTP and MELD score, and CTP score were 0820, 0.915, 0.888, and 0

    It is sometimes difficult to assess I-131 lung uptake at the initial I-131 therapy because of strong artifacts from I-131 uptake in the thyroid bed. The aim of this study was to analyze the lung uptake at the second I-131 therapy for lung metastasis in patients who did not have lung uptake at the initial therapy from differentiated thyroid carcinoma (DTC). Then, we also analyzed the relationship between the initial lung uptake and short-term outcome after I-131 therapies. This study included 62 DTC patients with lung metastasis. The patients were classified into 2 groups according to the lung uptake at the initial I-131 therapy such as patients with lung uptake (positive uptake group n=31) and those without lung uptake (negative uptake group n=31). The lung uptake was analyzed at the second therapy in both groups. The short-term outcome was also analyzed based on the CT findings of lung metastasis size and serum thyroglobulin level between the two groups. The positive uptake group showed positive lung uptake at the second therapy in 23 patients (74%), whereas none of negative uptake group showed any lung uptake at the second therapy (P < 0.01). The positive uptake group significantly decreased in the size of lung metastasis from the initial therapy to the second therapy (20.0 ± 11.7 to 16.6 ± 9.6 mm, P < 0.01) with further decrease after the second therapy (P < 0.05). The serum thyroglobulin level was also significantly decreased from the initial therapy to the second therapy (4348 ± 7011 to 2931 ± 4484 ng/ml, P < 0.05). In contrast, the negative uptake group significantly increased in the size of lung metastasis from the initial therapy to the second therapy (17.3 ± 12.2 to 19.9 ± 14.3 mm, P < 0.01) with further increase after the second therapy (P < 0.01). No patients without lung uptake at the initial I-131 therapy showed lung uptake at the second therapy, or showed treatment effect. Therefore, second I-131 therapy for these patients with initially

    To develop a feasible model for monitoring short-term outcome of clinical care trajectories for hospitals in the Netherlands using data obtained from hospital information systems for identifying hospital variation. Retrospective analysis of collected data from hospital information systems combined with clinical indicator definitions to define and compare short-term outcomes for three gastrointestinal pathways using the concept of Textbook Outcome. 62 Dutch hospitals. 45 848 unique gastrointestinal patients discharged in 2015. A broad range of clinical outcomes including length of stay, reintervention, readmission and doctor-patient counselling. Patients undergoing endoscopic retrograde cholangiopancreatography (ERCP) for gallstone disease (n=4369), colonoscopy for inflammatory bowel disease (IBD; n=19 330) and colonoscopy for colorectal cancer screening (n=22 149) were submitted to five suitable clinical indicators per treatment. The percentage of all patients who met all five criteria was 54%±9% (SD) for ERCP treatment. For IBD this was 47%±7% of the patients, and for colon cancer screening this number was 85%±14%. This study shows that reusing data obtained from hospital information systems combined with clinical indicator definitions can be used to express short-term outcomes using the concept of Textbook Outcome without any excess registration. This information can provide meaningful insight into the clinical care trajectory on the level of individual patient care. Furthermore, this concept can be applied to many clinical trajectories within gastroenterology and beyond for monitoring and improving the clinical pathway and outcome for patients. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

    In this study, we focus on the induced degradation and spatial inhomogeneity of organic photovoltaic devices under different environmental conditions, uncoupled from the influence of any auxiliary hole-transport (HT) layer. During testing of the corresponding devices comprising the standard photoactive layer of poly(3-hexylthiophene) as donor, blended with phenyl-C 61 -butyric acid methyl ester as acceptor, a comparison was made between the nonencapsulated devices upon exposure to argon in the dark, dry air in the dark, dry air with illumination, and humid air in the dark. The impact on the active layer's photophysics is discussed, along with the device physics in terms of integral solar cell performance and spatially resolved photocurrent distribution with point-to-point analysis of the diode characteristics to determine the origin of the observed integrated organic photovoltaic device behavior. The results show that even without the widely used hygroscopic HT layer, poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate), humidity is still a major factor in the short-term environmental degradation of organic solar cells with this architecture, and not only oxygen or light, as is often reported. Different from previous reports where water-induced device degradation was spatially homogeneous and formation of Al 2 O 3 islands was only seen for oxygen permeation through pinholes in aluminum, we observed insulating islands merely after humidity exposure in the present study. Further, we demonstrated with laser beam induced current mapping and point-to-point diode analysis that the water-induced performance losses are a result of the exposed device area comprising regions with entirely unaltered high output and intact diode behavior and those with severe degradation showing detrimentally lowered output and voltage-independent charge blocking, which is essentially insulating behavior. It is suggested that this is caused by transport of water through pinholes to the

    Point estimation is particularly important in predicting weight loss in individuals or small groups. In this analysis, a new health response function is based on a model of human response over time to estimate long-term health outcomes from a change point in short-term linear regression. This important estimation capability is addressed for small groups and single-subject designs in pilot studies for clinical trials, medical and therapeutic clinical practice. These estimations are based on a change point given by parameters derived from short-term participant data in ordinary least squares (OLS) regression. The development of the change point in initial OLS data and the point estimations are given in a new semiparametric ratio estimator (SPRE) model. The new response function is taken as a ratio of two-parameter Weibull distributions times a prior outcome value that steps estimated outcomes forward in time, where the shape and scale parameters are estimated at the change point. The Weibull distributions used in this ratio are derived from a Kelvin model in mechanics taken here to represent human beings. A distinct feature of the SPRE model in this article is that initial treatment response for a small group or a single subject is reflected in long-term response to treatment. This model is applied to weight loss in obesity in a secondary analysis of data from a classic weight loss study, which has been selected due to the dramatic increase in obesity in the United States over the past 20 years. A very small relative error of estimated to test data is shown for obesity treatment with the weight loss medication phentermine or placebo for the test dataset. An application of SPRE in clinical medicine or occupational therapy is to estimate long-term weight loss for a single subject or a small group near the beginning of treatment.

    The aim of the study was to assess differences in verbal fluency, working memory and executive functions in two subgroups of alcohol-dependent patients, those undergoing short-term abstinence (STA) and those undergoing long-term abstinence (LTA), and to compare the level of cognitive functions in patients after long-term abstinence with healthy subjects. The study group consisted of 106 alcohol-dependent patients (53 immediately after drinking at least 3 days and 53 after at least one-year abstinence). The control group comprised 53 subjects, whose age, sex and education levels matched those of the patients in the experimental group. The dependence intensity was assessed using SADD and MAST scales. The neuropsychological assessment was based on the FAS Test, Stroop Test and TMT A&B Test. The results obtained for alcohol-dependent patients revealed significant disturbances of cognitive functions. Such results indicate the presence of severe frontal cerebral cortex dysfunctions. Frontal cortex dysfunctions affecting the verbal fluency and working memory subsystems and the executive functions also persisted during long-term abstinence periods. No significant correlations between the duration of dependence, quantity of alcohol consumed and efficiency of the working memory and executive functions were observed in alcohol-dependent subjects after short-term or long-term abstinence.

    Full Text Available Non-Invasive Brain Stimulation (NIBS is a relatively new therapeutic approach that has shown beneficial effects in Autism Spectrum Disorder (ASD. One question to be answered is how enduring its neuromodulatory effect could be. Twenty-four patients with ASD (mean age: 12.2 years received 20 sessions of NIBS over the left dorsolateral prefrontal cortex (L-DLPFC. They were randomized into two groups with two (G1 or three (G2 clinical evaluations before NIBS. Both groups had a complete follow-up at six months after the intervention, with the aim of determining the short-term outcome using the total score on the Autism Behavior Checklist, Autism Treatment Evaluation Checklist, and the Autism Diagnostic Interview. Transcranial Direct Current Stimulation (tDCS was used in ASD patients aged <11 years, and repetitive Transcranial Magnetic Stimulation (rTMS for 11–13-year-olds. Observation points were at one, three, and six months after completing all the sessions of NIBS. A significant reduction in the total score on the three clinical scales was observed and maintained during the first six months after treatment, with a slight and non-significant tendency to increase the scores in the last evaluation. Twenty sessions of NIBS over the L-DLPFC improves autistic symptoms in ASD children, with a lasting effect of six months.

    New research has suggested the clinical use of lysergic acid diethylamide (LSD) and psilocybin in selected patient populations. However, concerns about the clinical use of LSD were advanced in a large Danish follow-up study that assessed 151 LSD-treated psychiatric patients approximately 25 years after their treatment in the 1960s. The purpose of the present study was to give a retrospective account of the short-term outcome of LSD treatment in these 151 Danish psychiatric patients. The LSD case material in the Danish State Archives consists of medical case records of 151 LSD-treated patients, who complained and received economic compensation with the LSD Damages Law. The author carefully read and reviewed the LSD case material. LSD was used to treat a wide spectrum of mental disorders. Independent of diagnoses, 52 patients improved, and 48 patients worsened acutely with the LSD treatment. In a subgroup of 82 neurotic patients, the LSD dose-index (number of treatments multiplied by the maximal LSD dose) indicated the risk of acute worsening. In another subgroup of 19 patients with obsessive-compulsive neurosis, five patients later underwent psychosurgery. A small subgroup of 12 patients was treated with psilocybin. The long-term outcome was poor in most of the patients. Despite the significant limitations to a retrospective design, this database warrants caution in mental health patients. The use of LSD and psilocybin in mental health patients may be associated with serious short- and long-term side effects. Until further trials with rigorous designs have cleared these drugs of their potential harms, their clinical utility in these groups of patients has not been fully clarified.

    Evidence indicates that impaired immunocompetence and nutritional status adversely affect short-term and long-term outcomes of patients with cancer. We aimed to evaluate the clinical significance of preoperative immunocompetence and nutritional status according to Onodera's prognostic nutrition index (PNI) among patients who underwent curative gastrectomy for gastric cancer (GC).This study included 260 patients with stage II/III GC who underwent R0 resection. The predictive values of preoperative nutritional status for postoperative outcome (morbidity and prognosis) were evaluated. Onodera's PNI was calculated as follows: 10 × serum albumin (g/dL) + 0.005 × lymphocyte count (per mm).The mean preoperative PNI was 47.8. The area under the curve for predicting complications was greater for PNI compared with the serum albumin concentration or lymphocyte count. Multivariate analysis identified preoperative PNI < 47 as an independent predictor of postoperative morbidity. Moreover, patients in the PNI < 47 group experienced significantly shorter overall and disease-free survival compared with those in the PNI ≥ 47 group, notably because of a higher prevalence of hematogenous metastasis as the initial recurrence. Subgroup analysis according to disease stage and postoperative adjuvant treatment revealed that the prognostic significance of PNI was more apparent in patients with stage II GC and in those who received adjuvant chemotherapy.Preoperative PNI is easy and inexpensive to determine, and our findings indicate that PNI served as a significant predictor of postoperative morbidity, prognosis, and recurrence patterns of patients with stage II/III GC.

    Number interval bisection consists of estimating the mid-number within a pair (1-9=>5). Healthy adults and right-brain damage patients can show biased performance in this task, underestimating and overestimating the mid-number, respectively. The role of visuospatial attention during this task, and its interplay with other cognitive abilities (e.g., working memory) is still object of debate. In this study we explored the relation between visuospatial attention and individual differences in working memory and executive functions during number interval bisection. To manipulate the deployment of visuospatial attention, healthy participants tracked a dot moving to the left or moving to the right while bisecting numerical intervals. We also collected information concerning verbal and visuospatial short-term memory span, and concerning verbal and visuospatial fluency scores. Beside replicating what is typically observed in this task (e.g., underestimation bias), a correlation was observed between verbal short-term memory and bisection bias, and an interesting relation between performance in the number interval bisection, verbal short-term memory, and visuospatial attention. Specifically, performance of those participants with low verbal span was affected by the direction of the moving dot, underestimating at a larger extent when the dot moved leftward than rightward. Finally, it was also observed that participants' verbal fluency ability contributed in the generation of biases in the numerical task. The finding of the involvement of abilities belonging to the verbal domain contributes to unveil the multi-componential nature of number interval bisection. Considering the debate on the nature of number interval bisection and its use in the clinical assessment of deficits following brain damage, this finding may be interesting also from a clinical perspective.

    Over the past decades, a substantial amount of research has been conducted to model and forecast climatic variables. In this study, Nonparametric Functional Data Analysis (NPFDA) methods are applied to forecast air temperature and wind speed time series in Abu Dhabi, UAE. The dataset consists of hourly measurements recorded for a period of 29 years, 1982-2010. The novelty of the Functional Data Analysis approach is in expressing the data as curves. In the present work, the focus is on daily forecasting and the functional observations (curves) express the daily measurements of the above mentioned variables. We apply a non-linear regression model with a functional non-parametric kernel estimator. The computation of the estimator is performed using an asymmetrical quadratic kernel function for local weighting based on the bandwidth obtained by a cross validation procedure. The proximities between functional objects are calculated by families of semi-metrics based on derivatives and Functional Principal Component Analysis (FPCA). Additionally, functional conditional mode and functional conditional median estimators are applied and the advantages of combining their results are analysed. A different approach employs a SARIMA model selected according to the minimum Akaike (AIC) and Bayessian (BIC) Information Criteria and based on the residuals of the model. The performance of the models is assessed by calculating error indices such as the root mean square error (RMSE), relative RMSE, BIAS and relative BIAS. The results indicate that the NPFDA models provide more accurate forecasts than the SARIMA models. Key words: Nonparametric functional data analysis, SARIMA, time series forecast, air temperature, wind speed

    Aim of this study is to report the mid-term outcomes of a large series of patients treated with peroral endoscopic myotomy (POEM) in a single European center. POEM is a recently developed treatment of achalasia, which combines the efficacy of surgical myotomy, with the benefits of an endoscopic procedure. Previous studies, including few patients with a short-term follow-up, showed excellent results on dysphagia relief. The first 100 adult patients treated in a single tertiary referral center were retrospectively identified and included in this study (41 men, mean age 48.4 years). Patients were treated according to a standard technique. Follow-up data, including clinical evaluation, and results of esophagogastroduodenoscopy (EGD), manometry, and pH monitoring were collected and analyzed. POEM was completed in 94% of patients. Mean operative time was 83 minutes (49-140  minutes). No complications occurred. Patients were fed after a median of 2 days (1-4 days). A mean follow-up of 11 months (3-24 months) was available for 92 patients. Clinical success was documented in 94.5% of patients. Twenty-four-hour pH monitoring documented Gastro-Esophageal Reflux Disease (GERD) in 53.4% of patients. However, only a minority of patients had heartburn (24.3%) or esophagitis (27.4%), and these patients were successfully treated with proton-pump inhibitors. Our results confirm the efficacy of POEM in a large series of patients, with a mean follow-up of 11 months. Should our results be confirmed by long-term follow-up studies, POEM may become one of the first-line therapies of achalasia in the next future.

    Full Text Available Mycetoma is a neglected, chronic, localized, progressively destructive, granulomatous infection caused either by fungi (eumycetoma or by aerobic actinomycetes (actinomycetoma. It is characterized by a triad of painless subcutaneous mass, multiple sinuses and discharge containing grains. Mycetoma commonly affects young men aged between 20 and 40 years with low socioeconomic status, particularly farmers and herdsmen.A 30 year-old male farmer from an ethnic minority in Phin District, Savannakhet Province, Lao PDR (Laos developed a painless swelling with multiple draining sinuses of his right foot over a period of approximately 3 years. X-ray of the right foot showed osteolysis of tarsals and metatarsals. Aerobic culture of sinus discharge yielded large numbers of Staphylococcus aureus and a slow growing Gram-positive rod. The organism was subsequently identified as Nocardia aobensis by 16S ribosomal RNA gene sequencing. The patient received antimicrobial treatment with amikacin and trimethoprim-sulfamethoxazole according to consensus treatment guidelines. Although slight improvement was noted the patient left the hospital after 14 days and did not take any more antibiotics. Over the following 22 weeks the swelling of his foot subsequently diminished together with healing of discharging sinuses.This is the first published case of Actinomycetoma caused by Nocardia aobensis and the second case of Actinomycetoma from Laos. A treatment course of only 14 days with amikacin and trimethoprim-sulfamethoxazole was apparently sufficient to cure the infection, although long-term treatment up to one year is currently recommended. Treatment trials or prospective descriptions of outcome for actinomycetoma should investigate treatment efficacy for the different members of Actinomycetales, particularly Nocardia spp., with short-term and long-term treatment courses.

    Intermittent fasting dietary restriction (IF-DR) is recently reported to be an effective intervention to retard age associated disease load and to promote healthy aging. Since sustaining long term caloric restriction regimen is not practically feasible in humans, so use of alternate approach such as late onset short term IF-DR regimen which is reported to trigger similar biological pathways is gaining scientific interest. The current study was designed to investigate the effect of IF-DR regimen implemented for 12 weeks in middle age rats on their motor coordination skills and protein and DNA damage in different brain regions. Further, the effect of IF-DR regimen was also studied on expression of energy regulators, cell survival pathways and synaptic plasticity marker proteins. Our data demonstrate that there was an improvement in motor coordination and learning response with decline in protein oxidative damage and recovery in expression of energy regulating neuropeptides. We further observed significant downregulation in nuclear factor kappa B (NF-κB) and cytochrome c (Cyt c) levels and moderate upregulation of mortalin and synaptophysin expression. The present data may provide an insight on how a modest level of short term IF-DR, imposed in middle age, can slow down or prevent the age-associated impairment of brain functions and promote healthy aging by involving multiple regulatory pathways aimed at maintaining energy homeostasis.

    2010-01-01

    This paper proposed a price forecasting system for electric market participants to reduce the risk of price volatility. Combining the Radial Basis Function Network (RBFN) and Orthogonal Experimental Design (OED), an Enhanced Radial Basis Function Network (ERBFN) has been proposed for the solving process. The Locational Marginal Price (LMP), system load, transmission flow and temperature of the PJM system were collected and the data clusters were embedded in the Excel Database according to the year, season, workday and weekend. With the OED applied to learning rates in the ERBFN, the forecasting error can be reduced during the training process to improve both accuracy and reliability. This would mean that even the ''spikes'' could be tracked closely. The Back-propagation Neural Network (BPN), Probability Neural Network (PNN), other algorithms, and the proposed ERBFN were all developed and compared to check the performance. Simulation results demonstrated the effectiveness of the proposed ERBFN to provide quality information in a price volatile environment. (author)

    Researchers have designed training methods that can be used to improve mental health and to test the efficacy of education programs. However, few studies have demonstrated broad transfer from such training to performance on untrained cognitive activities. Here we report the effects of two interactive computerized training programs developed for preschool children: one for music and one for visual art. After only 20 days of training, only children in the music group exhibited enhanced performance on a measure of verbal intelligence, with 90% of the sample showing this improvement. These improvements in verbal intelligence were positively correlated with changes in functional brain plasticity during an executive-function task. Our findings demonstrate that transfer of a high-level cognitive skill is possible in early childhood.

    To compare short-term results of total mesorectal excision (TME) for mid and low rectal cancer, achieved by transanal (TaTME), laparoscopic (LaTME), and open (OpTME) approaches. The impact of TaTME on the surgical treatment of mid and low rectal cancer has yet to be clarified. This is a case-matched study, based on data from a prospectively maintained database of patients who underwent TaTME from May 2015 to March 2017, and a retrospective chart review of patients who underwent LaTME and OpTME in the previous period. Each patient in the TaTME group was matched to one LaTME and one OpTME based on sex, BMI, tumor status, and the height of the tumor from the anal verge. Primary end-points were rates of positive circumferential resection margin (CRM), distal resection margin, and the macroscopic quality of the surgical specimen. Composite of these outcomes was compared as an indication for successful surgery. Secondary end-points included intraoperative data and postoperative course and complications. Three hundred patients were included (TaTME = 100, LaTME = 100, OpTME = 100). The three groups were comparable in the baseline characteristics. TaTME resulted in lower rates of incomplete TME specimens than LaTME, but not OpTME (P = 0.016, P = 0.750, respectively). The rates of CRM involvement, mean CRM distance, and the percentages of successful surgery were comparable among the three groups (P = 0.368). The conversion to open surgery occurred only in the LaTME group. TaTME resulted in shorter operation time and less blood loss than the other two groups (P benefits over other approaches. The pathological results were not significantly superior to LaTME and OpTME. The procedure is however feasible and safe. Further studies are needed to evaluate the long-term oncological and quality of life outcomes.

    This study was designed to mainly evaluate the anti-infective effects of perioperative probiotic treatment in patients receiving confined colorectal cancer (CRC) respective surgery. From November 2011 to September 2012, a total of 60 patients diagnosed with CRC were randomly assigned to receive probiotic (n = 30) or placebo (n = 30) treatment. The operative and post-operative clinical results including intestinal cleanliness, days to first - flatus, defecation, fluid diet, solid diet, duration of pyrexia, average heart rate, length of intraperitoneal drainage, length of antibiotic therapy, blood index changes, rate of infectious and non-infectious complications, postoperative hospital stay, and mortality were investigated. The patient demographics were not significantly different (p > 0.05) between the probiotic treated and the placebo groups. The days to first flatus (3.63 versus 3.27, p = 0.0274) and the days to first defecation (4.53 versus 3.87, p = 0.0268) were significantly improved in the probiotic treated patients. The incidence of diarrhea was significantly lower (p = 0.0352) in probiotics group (26.67%, 8/30) compared to the placebo group (53.33%, 16/30). There were no statistical differences (p > 0.05) in other infectious and non-infectious complication rates including wound infection, pneumonia, urinary tract infection, anastomotic leakage, and abdominal distension. In conclusion, for those patients undergoing confined CRC resection, perioperative probiotic administration significantly influenced the recovery of bowel function, and such improvement may be of important clinical significance in reducing the short-term infectious complications such as bacteremia.

    Kidney function was studied in six normal males before and during a 2 h glucagon (10 ng/kg/min) infusion. The following variables were determined during each 20 min clearance period; glomerular filtration rate (GFR), renal plasma-flow (RPF) , filtration fraction (FF), urinary albumin and beta2......-microglobulin-excretion rates. Glucagon infusion resulted in a fourfold increase in plasma glucagon concentration. The infusion induced a significant increase in GFR (+9%), FF (+9%) and urinary beta2-microglobulin excretion rate (+32%), (p less than 0.01). RPF and urinary albumin excretion rates were...

    Kidney function was studied in 9 normal males before and during a 2 h growth hormone (GH) infusion of 50 ng/kg/min. The following variables were measured during each 20 min clearance period: glomerular filtration rate, GFR, effective renal plasma flow, RPF (steady state infusion technique...... with urinary collections using [125I]iothalamate and [131I]iodohippurate), and urinary albumin and beta2-microglobulin excretion rates (radioimmunoassays). The GH infusion resulted in a 10-fold increase in plasma GH concentration. All the above mentioned variables remained practically unchanged during...... the infusion except for a small (-5%) but significant decrease in renal plasma flow (P less than 0.01). Our negative results contrast to the findings of increased GFR and RPF during prolonged GH administration and suggest that GH requires several hours or days for its renal effects to become manifest....

    Deep earthwork activities carried out before vineyard plantation completely upset soil profile and characteristics. The resulting soil features are often much more similar to the underlying substratum than original soil profile. The time needed to recover soil functions is ecologically relevant and affects vine phenology and grape yield, particularly in organic viticulture. The general aim of this research work was to investigate the time needed to recover soil functions after the earthworks made before vine plantation. This study compared for a four years period physical and chemical properties, microbial and mesofauna communities, in new and old vineyards, cultivated on the same soil type. The experiment was conducted in a farm of the Chianti Classico district (Central Italy), on hills of high altitude (400-500 m a.s.l.) on clayey-calcareous flysches, with stony and calcareous soils (Haplic Cambisol (Calcaric, Skeletic)). The reference vine cultivar was Sangiovese. The older vineyard was planted in 2000, after slope reshaping by bulldozing and back hoe ploughing down to about 0.8-1.0 m. The new vineyard was planted in 2011 after an equivalent earthwork carried out in the summer of 2009. Both vineyards were organically managed and only compost at the rate of 1,000 kg ha-1 -a was added every year. The new vineyard was periodically cultivated by mechanical tillage, while the older only at alternate rows. Soil samples from the first 15 cm depth were collected in 4 replicates in the younger as well as in the older vineyard during the springtime of 2010-2013; in the older vineyard, two samples were from the periodically cultivated swaths and two under permanent grass cover. Samples were analysed for physical (particle size, field capacity, wilting point), chemical (pH, electrical conductivity, lime, active lime, organic carbon, total nitrogen), microbiological (soil respiration, microbial biomass, DGGE), and mesofauna features (abundance, taxa richness, BSQ index and

    Rosemary (Rosmarinus officinalis L.) has traditional reputations that justify investigation for a potential role in reducing widespread cognitive decline in the elderly. A randomized, placebo-controlled, double-blinded, repeated-measures crossover study was conducted to investigate possible acute effects of dried rosemary leaf powder on cognitive performance. Twenty-eight older adults (mean age, 75 years) were tested using the Cognitive Drug Research computerized assessment system 1, 2.5, 4, and 6 hours following a placebo and four different doses of rosemary. Doses were counterbalanced, and there was a 7-day washout between visits. There was a biphasic dose-dependent effect in measures of speed of memory: the lowest dose (750 mg) of rosemary had a statistically significant beneficial effect compared with placebo (P=.01), whereas the highest dose (6,000 mg) had a significant impairing effect (Pmemory is a potentially useful predictor of cognitive function during aging. The positive effect of the dose nearest normal culinary consumption points to the value of further work on effects of low doses over the longer term.

    We investigated the hypothesis that arousal recruits attention to item information, thereby disrupting working memory processes that help bind items to context. Using functional magnetic resonance imaging, we compared brain activity when participants remembered negative or neutral picture-location conjunctions (source memory) versus pictures only. Behaviorally, negative trials showed disruption of short-term source, but not picture, memory; long-term picture recognition memory was better for negative than for neutral pictures. Activity in areas involved in working memory and feature integration (precentral gyrus and its intersect with superior temporal gyrus) was attenuated on negative compared with neutral source trials relative to picture-only trials. Visual processing areas (middle occipital and lingual gyri) showed greater activity for negative than for neutral trials, especially on picture-only trials.

    Picture and word triads were tested in a Brown-Peterson short-term retention task at varying delay intervals (3, 10, or 30 sec) and under acoustic and simultaneous acoustic and visual distraction. Pictures were superior to words at all delay intervals under single acoustic distraction. Dual distraction consistently reduced picture retention while simultaneously facilitating word retention. The results were interpreted in terms of the dual coding hypothesis with modality-specific interference effects in the visual and acoustic processing systems. The differential effects of dual distraction were related to the introduction of visual interference and differential levels of functional acoustic interference across dual and single distraction tasks. The latter was supported by a constant 2/1 ratio in the backward counting rates of the acoustic vs. dual distraction tasks. The results further suggest that retention may not depend on total processing load of the distraction task, per se, but rather that processing load operates within modalities.

    Kidney function was studied in nine, metabolically well controlled, short-term insulin-dependent male diabetics before and during glucagon infusion of 4 to 5 and 8 to 10 ng/kg/min. Glomerular filtration rate, effective renal plasma flow (steady-state infusion technique, with urinary collections......, using 125I-iothalamate and 131I-iodohippurate), and urinary albumin and beta 2-microglobulin excretion rates were measured. The mean plasma glucagon concentration increased during infusion from 254 +/- 19 pg/ml to 440 +/- 31 pg/ml (low dose) and 730 +/- 52 pg/ml (high dose). Glomerular filtration rate...... increased in all subjects from 133 +/- 5 before the glucagon infusion to 141 +/- 4 with the low dose, and 148 +/- 7 ml/min/1.73 m2 with the high dose (p

    To report approach, technical success, safety, and short-term outcomes of thoracic duct stent-graft reconstruction for the treatment of chylothorax. Two patients, 1 (50%) male and 1 (50%) female, with mean age of 38 years (range: 16-59 years) underwent endolymphatic thoracic duct stent-graft reconstruction between September 2016 and July 2017. Patients had radiographic left-sided chylothoraces (n = 2) from idiopathic causes (n = 1) and heart transplantation (n = 1). In both (100%) patients, antegrade lymphatic access was used to opacify the thoracic duct after which retrograde access was used for thoracic duct stent-graft placement. Pelvic lymphangiography technical success, antegrade cisterna chyli cannulation technical success, thoracic duct opacification technical success, retrograde thoracic duct access technical success, thoracic duct stent-graft reconstruction technical success, ethiodized oil volume, contrast volume, estimated blood loss, procedure time, fluoroscopy time, radiation dose, clinical success, complications, deaths, and follow-up were recorded. Pelvic lymphangiography, antegrade cisterna chyli cannulation, thoracic duct opacification, retrograde thoracic duct access, and thoracic duct stent-graft reconstruction were technically successful in both (100%) patients. Mean ethiodized oil volume was 8 mL (range: 5-10 mL). Mean contrast volume was 13 mL (range: 5-20 mL). Mean estimated blood loss was 13 mL (range: 10-15 mL). Mean fluoroscopy time was 50.4 min (range: 31.2-69.7 min). Mean dose area product and reference air kerma were 954.4 μGmy 2 (range: 701-1,208 μGmy 2 ) and 83.5 mGy (range: 59-108 mGy), respectively. Chylothorax resolved in both (100%) patients. There were no minor or major complications directly related to the procedure. Thoracic duct stent-graft reconstruction may be a technically successful and safe alternative to thoracic duct embolization, disruption, and surgical ligation for the treatment of chylothorax

    Full Text Available Abstract Background This retrospective study analyzed the effectiveness of intrathoracic negative pressure therapy for debilitated patients with empyema and compared the short-term and long-term outcomes of three different intrapleural vacuum-assisted closure (VAC techniques. Methods We investigated 43 consecutive (preseptic patients with poor general condition (Karnofsky index ≤ 50 % and multimorbidity (≥ 3 organ diseases or immunosuppression, who had been treated for primary, postoperative, or recurrent pleural empyema with VAC in combination with open window thoracostomy (OWT-VAC with minimally invasive technique (Mini-VAC, and instillation (Mini-VAC-Instill. Results The overall duration of intrathoracic vacuum therapy was 14 days (5–48 days. Vacuum duration in the Mini-VAC and Mini-VAC-Instill groups (12.4 ± 5.7 and 10.4 ± 5.4 days was significantly shorter (p = 0.001 than in the group treated with open window thoracostomy (OWT-VAC (20.3 ± 9.4 days. No major complication was related to intrathoracic VAC therapy. Chest wall closure rates were significantly higher in the Mini-VAC and Mini-VAC-Instill groups than in the OWT-VAC group (p = 0.034 and p = 0.026. Overall, the mean postoperative length of stay in hospital (LOS was 21 days (median 18, 6–51 days.

    To investigate the short-term effects of maxillary distraction osteogenesis (DO) on temporomandibular joint (TMJ) function in 21 subjects with cleft lip and palate (CLP). Design - Morphological changes in the maxillofacial region were measured using lateral cephalometric radiographs taken immediately before (pre-DO) and after DO (post-DO) and 1 year after DO (1-year follow-up). A questionnaire was evaluated using a visual analog scale. A chi-square test was used to compare the prevalence of TMJ symptoms between pre-DO and 1-year follow-up. The Spearman correlation coefficient was used to determine the correlation between changes in cephalometric variables and TMJ symptoms in association with maxillary DO. Statistical significance was set at p < 0.05. Results - The ANB (anteroposterior relationship of the maxilla with the mandible) angle and the mandibular plane angle at pre-DO, post-DO, and 1-year follow-up were -4.3 degrees , +5.8 degrees , +4.3 degrees and 32.1 degrees , 33.5 degrees , 33.6 degrees , respectively. The average amounts of anterior and downward movement of the maxilla at post-DO and 1-year follow-up were 8.3, -1.3 and 0.9, 1.1 mm, respectively. The prevalence of TMJ symptoms showed no significant increase in association with maxillary DO. Moreover, there was no significant correlation between changes in cephalometric variables and TMJ symptoms. Conclusion - These results suggest that there was no short-term (i.e., up to 1 year after DO) effect of maxillary DO on TMJ function in subjects with CLP.

    To determine the short-term effect of fluoroscopic-guided steroid injection therapy of lumbar facet cyst-induced radicular pain. Seventeen patients with radiculopathy due to lumbar synovial cysts, who were treated with fluoroscopically guided injection, were retrospectively evaluated. All plain radiographic images and MR images before the therapy were reviewed. Five patients underwent only the facet joint injection, whereas twelve patients underwent the facet joint injection with perineural injection therapy. The clinical course of pain was evaluated on the first follow-up after therapy. Effective pain relief was achieved in 11 (64.7%) of the 17 patients. Among 12 patients who underwent facet joint injection with perineural injection, 9 patients (75%) had an effective pain relief. Of 5 patients, 2 (40%) patients only took the facet joint injection and had an effective pain relief. Fluoroscopic-guided steroid injection therapy shows a good short-term effect in patients with symptomatic lumbar facet joint synovial cysts.

    Bertram J Jobst

    Full Text Available Non-invasive end-points for interventional trials and tailored treatment regimes in chronic obstructive pulmonary disease (COPD for monitoring regionally different manifestations of lung disease instead of global assessment of lung function with spirometry would be valuable. Proton nuclear magnetic resonance imaging (1H-MRI allows for a radiation-free assessment of regional structure and function. The aim of this study was to evaluate the short-term reproducibility of a comprehensive morpho-functional lung MRI protocol in COPD.20 prospectively enrolled COPD patients (GOLD I-IV underwent 1H-MRI of the lung at 1.5T on two consecutive days, including sequences for morphology, 4D contrast-enhanced perfusion, and respiratory mechanics. Image quality and COPD-related morphological and functional changes were evaluated in consensus by three chest radiologists using a dedicated MRI-based visual scoring system. Test-retest reliability was calculated per each individual lung lobe for the extent of large airway (bronchiectasis, wall thickening, mucus plugging and small airway abnormalities (tree in bud, peripheral bronchiectasis, mucus plugging, consolidations, nodules, parenchymal defects and perfusion defects. The presence of tracheal narrowing, dystelectasis, pleural effusion, pulmonary trunk ectasia, right ventricular enlargement and, finally, motion patterns of diaphragma and chest wall were addressed.Median global scores [10(Q1:8.00;Q3:16.00 vs.11(Q1:6.00;Q3:15.00] as well as category subscores were similar between both timepoints, and kappa statistics indicated "almost perfect" global agreement (ĸ = 0.86, 95%CI = 0.81-0.91. Most subscores showed at least "substantial" agreement of MRI1 and MRI2 (ĸ = 0.64-1.00, whereas the agreement for the diagnosis of dystelectasis/effusion (ĸ = 0.42, 95%CI = 0.00-0.93 was "moderate" and of tracheal abnormalities (ĸ = 0.21, 95%CI = 0.00-0.75 "fair". Most MRI acquisitions showed at least diagnostic quality at

    To investigate the impact of the baseline status of patients with hepatitis B virus-associated acute-on-chronic liver failure on short-term outcomes. A retrospective study was conducted that included a total of 138 patients with hepatitis B virus-associated acute-on-chronic liver failure admitted to the Department of Infectious Diseases, Taihe Hospital, Hubei University of Medicine, from November 2013 to October 2016. The patients were divided into a poor prognosis group (74 patients) and a good prognosis group (64 patients) based on the disease outcome. General information, clinical indicators and prognostic scores of the patients' baseline status were analyzed, and a prediction model was established accordingly. Elder age, treatment with artificial liver support systems and the frequency of such treatments, high levels of white blood cells, neutrophils, neutrophil count/lymphocyte count ratio, alanine aminotransferase, gamma-glutamyl transferase, total bilirubin, urea, and prognostic scores as well as low levels of albumin and sodium were all significantly associated with the short-term outcomes of hepatitis B virus-associated acute-on-chronic liver failure. The predictive model showed that logit (p) = 3.068 + 1.003 × neutrophil count/lymphocyte count ratio - 0.892 × gamma-glutamyl transferase - 1.138 × albumin - 1.364 × sodium + 1.651 × artificial liver support therapy. The neutrophil count/lymphocyte count ratio and serum levels of gamma-glutamyl transferase, albumin and sodium were independent risk factors predicting short-term outcomes of hepatitis B virus-associated acute-on-chronic liver failure, and the administration of multiple treatments with artificial liver support therapy during the early stage is conducive to improved short-term outcomes.

    Single-port video-assisted thoracoscopic surgery (VATS) has been widely applied recently. However, there are still only few reports describing its use in mediastinum tumor resection. We present the technique of single-port video-assisted thoracoscopic mediastinum tumor resection and compare it with conventional VATS with regard to short-term outcome.We retrospectively enrolled 105 patients who received mediastinum surgery in Chang Gung Memorial Hospital. Sixteen patients received sternotomy or thoracotomy, 29 patients received single-port VATS, and 60 patients received conventional VATS (3 ports). The operative time, blood loss, postoperation day 1 pain score, discharge day pain score, and postoperative hospital stay were compared. In order to establish a well balanced cohort study, we also use propensity scores match (1:1) to compare the short-term clinical outcome in 2 groups.No operative deaths occurred in this study. Single-port VATS was associated with shorter operative time, lower postoperation day 1 pain score, and shorter postoperation hospital stay in our cohort study (P = 0.001, short-term outcome not inferior to conventional VATS in our cohort study. The long-term oncology outcome may require time and more enrolled patients to be further evaluated.

    Safety of oral sucrose, commonly used procedural analgesic in neonates, is questioned. To evaluate the effect of sucrose analgesia, for repeated painful procedures, on short-term neurobehavioral outcome of preterm neonates. Stable preterm neonates were randomized to receive either sucrose or distilled water orally, for every potentially painful procedure during the first 7 days after enrollment. Neurodevelopmental status at 40 weeks postconceptional age (PCA) measured using the domains of Neurobehavioral Assessment of Preterm Infants scale. A total of 93 newborns were analyzed. The baseline characteristics of the groups were comparable. No statistically significant difference was observed in the assessment at 40 weeks PCA, among the groups. Use of sucrose analgesia, for repeated painful procedures on newborns, does not lead to any significant difference in the short-term neurobehavioral outcome. © The Author [2015].

    Full Text Available In this clinical follow-up study, we examined the effect of clinical holistic medicine (psychodynamic short-term therapy complemented with bodywork on patients with poor self-assessed sexual functioning and found that this problem could be solved in 41.67% of the patients ((95% CI: 27.61–56.7%; 1.75 < NNT < 3.62, p = 0.05. The bodywork was inspired by the Marion Rosen method and helped the patients to confront painful emotions from childhood trauma(s, and thus accelerated and deepened the therapy. The goal of therapy was the healing of the whole life of the patient through Antonovsky-salutogenesis. In this process, rehabilitation of the character and purpose of life of the patient was essential, and assisted the patient to recover his or her sense of coherence (existential coherence. We conclude that clinical holistic medicine is the treatment of choice if the patient is ready to explore and assume responsibility for his or her existence (true self, and willing to struggle emotionally in the therapy to reach this important goal. When the patient heals existentially, quality of life, health, and ability to function in general are improved at the same time. The therapy was “mindful” in its focus on existential and spiritual issues. The patients received in average 14.8 sessions at the cost of 1,188 EURO.

    Full Text Available Aims. To investigate the effect of biliary stent placement without endoscopic sphincterotomy (EST on common bile duct stones (CBDS disappearance and the contribution of preserving the duodenal papilla function to reduce recurrence of CBDS. Methods. Sixty-six patients admitted for acute obstructive cholangitis due to CBDS who underwent biliary stent placement without EST for 2 years from March 2011 were evaluated retrospectively. The second endoscopic retrograde cholangiopancreatography (ERCP was performed for treatment of CBDS 3 to 4 months after the first ERCP. We estimated the rate of stone disappearance at the time of second ERCP. Results. CBDS disappearance was observed in 32 (48.5% of 66 patients. The diameter of the bile ducts and the diameter of CBDS in patients with CBDS disappearance were significantly smaller than in those with CBDS requiring extraction (p=0.007 and p<0.001, resp.. Stone disappearance was evident when the diameter of bile ducts and that of CBDS were <10 and 7 mm, respectively (p=0.002. Conclusions. Short-term stent placement without EST eliminates CBDS while preserving duodenal papilla function and may be suitable for treating CBDS in patients with nondilated bile ducts and small CBDS.

Even with visual list-presentation, verbal serial recall is particularly susceptible to disruption by irrelevant spoken stimuli that have the same identity as-but that are order-incongruent with-the to-be-remembered items. We test the view that such interference is because of the obligatory perceptual organization of the spoken stimuli yielding a sequence that competes with a subvocal motor-plan assembled to support the reproduction of the to-be-remembered list. In support of this view, the interference can be eliminated without changing either the identities or objective serial order of the spoken stimuli but merely by promoting a subjective perceptual organization that strips them of their order-incongruent relation to the to-be-remembered list (Experiment 1). The interference is also eliminated if subvocal motor sequence-planning is impeded via articulatory suppression (Experiment 2). The results are in line with the view that performance-limits in verbal serial STM are because of having to exploit perceptual and motor processes for purposes for which they did not evolve, not the inherently limited capacity of structures or mechanisms dedicated to storage.

    Kinesthetic illusions by visual stimulation (KiNVIS) enhances corticomotor excitability and activates motor association areas. The purpose of this study was to investigate the effect of KiNVIS induction on muscular output function after short-term immobilization. Thirty subjects were assigned to 3 groups: an immobilization group, with the left hand immobilized for 12h (immobilization period); an illusion group, with the left hand immobilized and additionally subjected to KiNVIS of the immobilized part during the immobilization period; and a control group with no manipulation. The maximum voluntary contraction (MVC), fluctuation of force (force fluctuation) during a force modulation task, and twitch force were measured both before (pre-test) and after (post-test) the immobilization period. Data were analyzed by performing two-way (TIME×GROUP) repeated measures ANOVA. The MVC decreased in the immobilization group only (pre-test; 37.8±6.1N, post-test; 32.8±6.9N, p<0.0005) after the immobilization period. The force fluctuation increased only in the immobilization group (pre-test; 2.19±0.54%, post-test; 2.78±0.87%, p=0.007) after the immobilization period. These results demonstrate that induction of KiNVIS prevents negative effect on MVC and force fluctuation after 12h of immobilization. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Objective To evaluate the effect of short-term hormone replacement therapy with tibolone 2.5 mg daily on endothelial function of healthy postmenopausal women, using flow-mediated dilation (FMD) of the brachial artery. Methods We performed a randomized, double-blinded, placebo-controlled study. A total of 100 healthy postmenopausal women were randomly allocated to receive tibolone (n = 50) or placebo (n = 50) for 28 days. Measurement of the FMD of the brachial artery was performed before and after the use of tibolone and placebo. Results A total of 31 women completed the study in the tibolone group, and 32 women completed the study in the control group. The results of the FMD measurements obtained from the women in the two groups before treatment were similar (0.018 and 0.091, for tibolone and placebo, p = 0.57). The values of the FMD in women who used tibolone and placebo, before and after the treatment, were similar in both groups. The numbers of women who presented an increase in the values of the FMD in both groups were also similar. Conclusion Our results demonstrate that the administration of 2.5 mg tibolone to healthy postmenopausal women for 28 days does not promote endothelial-dependent vasodilation, measured by FMD of the brachial artery.

    Visual short-term memory (VSTM) allows individuals to briefly maintain information over time for guiding behaviours. Because the contents of VSTM can be neutral or emotional, top-down influence in VSTM may vary with the affective codes of maintained representations. Here we investigated the neural mechanisms underlying the functional interplay of top-down attention with affective codes in VSTM using functional magnetic resonance imaging. Participants were instructed to remember both threatening and neutral objects in a cued VSTM task. Retrospective cues (retro-cues) were presented to direct attention to the hemifield of a threatening object (i.e., cue-to-threat) or a neutral object (i.e., cue-to-neutral) during VSTM maintenance. We showed stronger activity in the ventral occipitotemporal cortex and amygdala for attending threatening relative to neutral representations. Using multivoxel pattern analysis, we found better classification performance for cue-to-threat versus cue-to-neutral objects in early visual areas and in the amygdala. Importantly, retro-cues modulated the strength of functional connectivity between the frontoparietal and early visual areas. Activity in the frontoparietal areas became strongly correlated with the activity in V3a-V4 coding the threatening representations instructed to be relevant for the task. Together, these findings provide the first demonstration of top-down modulation of activation patterns in early visual areas and functional connectivity between the frontoparietal network and early visual areas for regulating threatening representations during VSTM maintenance.

    Laparoscopic surgery for rectal cancer is unpopular because it is technically challenging. Suitable training systems have not been widely studied or established despite the steep learning curve for this procedure. We developed a systematic training program that enables resident surgeons to perform laparoscopic low anterior resection (LLAR) for rectal cancer and evaluated the safety and feasibility of this training program. We analyzed prospectively gathered data on all LLARs for rectal cancer performed at a single center over a 7-year period. Patients were assessed for demographic characteristics, tumor characteristics, operative procedure, operative time, blood loss, conversion to open surgery, complications, time to bowel recovery, distal margin, and number of lymph nodes harvested. We compared the early surgical, oncological, and functional outcomes of LLARs performed by expert surgeons with those of LLARs performed by resident surgeons for both intraperitoneal and extraperitoneal rectal cancer. All analyses were performed on an intention-to-treat basis. A total of 137 patients met the inclusion criteria for this study. Of the 75 LLARs for intraperitoneal rectal cancer, 40 were performed by expert surgeons (I-E group) and 35 by resident surgeons (I-R group). Of the 62 LLARs for extraperitoneal rectal cancer, 51 were performed by expert surgeons (E-E group) and 11 by resident surgeons (E-R group). The operative time was longer in the E-R group than in the E-E group. The time to resumption of diet was longer in the I-E group than in the I-R group. The other early outcomes, including blood loss, anastomotic leakage, conversion to open surgery, and number of lymph nodes harvested, were similar in the I-E and I-R groups and in the E-E and E-R groups. Our systematic training program on LLAR for rectal cancer enables resident surgeons to perform this procedure safely early during residency, with acceptable short-term outcomes.

    To evaluate the effect of short-term intensive insulin treatment on β-cell function in newly diagnosed type 2 diabetes patients with apparently hyperglycemia, twenty-four newly diagnosed type 2 diabetes patients with FPG more than 12.0 mmol/L were treated by short-term transient intensive insulin in average 9.04-4.8 days. Their β-cell function was assessed by oral glucose tolerance test. The FPG, HbAlc and HOMA IR of patients were significantly decreased (P<0.01), while the insulin, the Area Under Curve (AUC) of insulin and HOMA β were significantly increased (P<0.01) after the treatment with insulin. Improvement of β-cell function can be induced by short-term intensive insulin treatment for newly diagnosed type 2 diabetes patients with apparently hyperglycemia. (authors)

    In 2015 a scientific workshop was held in Geneva, where updating the International Estimate of Short-Term Intake (IESTI) equations was suggested. This paper studies the effects of the proposed changes in residue inputs, large portions, variability factors and unit weights on the overall short-term dietary exposure estimate. Depending on the IESTI case equation, a median increase in estimated overall exposure by a factor of 1.0-6.8 was observed when the current IESTI equations are replaced by the proposed IESTI equations. The highest increase in the estimated exposure arises from the replacement of the median residue (STMR) by the maximum residue limit (MRL) for bulked and blended commodities (case 3 equations). The change in large portion parameter does not have a significant impact on the estimated exposure. The use of large portions derived from the general population covering all age groups and bodyweights should be avoided when large portions are not expressed on an individual bodyweight basis. Replacement of the highest residue (HR) by the MRL and removal of the unit weight each increase the estimated exposure for small-, medium- and large-sized commodities (case 1, case 2a or case 2b equations). However, within the EU framework lowering of the variability factor from 7 or 5 to 3 counterbalances the effect of changes in other parameters, resulting in an estimated overall exposure change for the EU situation of a factor of 0.87-1.7 and 0.6-1.4 for IESTI case 2a and case 2b equations, respectively.

    With regard to supination-external rotation type-IV (SER IV) ankle fractures, there is no consensus regarding which patient, injury, and treatment variables most strongly influence clinical outcome. The purpose of this investigation was to examine the impact of articular surface congruity on the functional outcomes of operatively treatment of SER IV ankle fractures. A prospectively generated database consisting of operatively treated SER IV ankle fractures was reviewed. Postoperative computed tomography (CT) scans were used to assess ankle joint congruity. Ankles were considered incongruent in the presence of >2 mm of articular step-off, intra-articular loose bodies, or an articular surface gap of >2 mm (despite an otherwise anatomic reduction) due to joint impaction and comminution. Patients with at least one year of clinical follow-up were eligible for analysis. The primary and secondary outcome measures were the Foot and Ankle Outcome Score (FAOS) and ankle motion. One hundred and eight SER IV fractures met our inclusion criteria. The average duration of follow-up was twenty-one months. Seventy-two patients (67%) had a congruent ankle joint, and thirty-six (33%) had elements of articular surface incongruity on postoperative CT scanning. These two groups were similar with regard to comorbidities and injury and treatment variables. At the time of the final follow-up, the group with articular incongruity had a significantly worse FAOS with regard to symptoms (p = 0.012), pain (p = 0.004), and activities of daily living (p = 0.038). Those with articular incongruity had worse average scores in the FAOS sport domain as well. No significant differences in ankle motion were found between the two groups. In this population of patients with an operatively treated SER IV ankle fracture, the presence of postoperative articular incongruity correlated with inferior early clinical outcomes. Orthopaedic surgeons should scrutinize ankle fracture reductions and strive for

    To evaluate the effect of short-term hormone replacement therapy with 0.625 mg conjugated estrogens daily on endothelial function of healthy postmenopausal women, using flow-mediated dilation (FMD) of the brachial artery. We performed a double-blinded, randomized, controlled trial over 3 years. Randomization was performed using computer-generated sorting. All participants were blinded to the use of conjugated equine estrogens (CEE) or placebo and FMD was assessed by a blinded examiner, before and after 28 days of medication. A total of 64 healthy postmenopausal women were selected and randomly assigned into two groups of treatment: 0.625 mg of CEE or placebo. FMD values were statistically different between the groups (p = 0.025): the group receiving CEE showed a FMD value of 0.011 compared to the placebo group (FMD = -0.082). The two groups were additionally evaluated for homogeneity through the Shapiro-Wilk test in respect to variables that could interfere with endothelial function such as age (p = 0.729), body mass index (p = 0.891), and time since menopause (p = 0.724). Other variables were excluded during selection of the participants such as chronic vascular conditions, smoking, and sedentary lifestyle. Our results demonstrate that the administration of 0.625 mg CEE for 28 days is effective in improving vascular nitric oxide-dependent dilation assessed by FMD of the brachial artery in postmenopausal women.

    To examine short-term clinical results of arthroscopic partial resection for type Ia avascular necrosis of the capitate. Patients who underwent arthroscopic treatment for type 1a avascular necrosis of the capitate with at least 1-year follow-up were identified through a retrospective chart review. The necrotic capitate head was arthroscopically resected with removal of the lunate facet and preservation of the scaphoid and hamate facets. Wrist range of motion, grip strength, and radiographic parameters--carpal height ratio, radioscaphoid angle, and radiolunate angle-were determined before surgery and at the latest follow-up. Patients completed a visual analog scale for pain; Disabilities of the Arm, Shoulder, and Hand measure; and the Patient-Rated Wrist Evaluation score before surgery and at the latest follow-up. Five patients (1 male, 4 females) with a mean age of 34 years (range, 16-49 years) and a mean follow-up duration of 20 months (range, 12-36 months) were identified during the chart review. All were type Ia (Milliez classification). Arthroscopy revealed fibrillation or softening with cartilage detachment at the lunate facet of the capitate head and an intact articular surface at the scaphoid and hamate facet. At the latest follow-up, the mean wrist flexion-extension was 123° (vs 81° before surgery) and grip strength was 74% (vs 37% before surgery). The visual analog scale score for pain; the Disabilities of the Arm, Shoulder, and Hand score; and the Patient-Rated Wrist Evaluation score before surgery showed a significant improvement following treatment. Radiographic parameters did not significantly change at the final follow-up, although the proximal carpal row trended toward flexion. Arthroscopic partial resection of the capitate head was an acceptable treatment for type Ia avascular necrosis of the capitate. It provided adequate pain relief and improved the range of wrist motion and grip strength during short-term follow-up. Therapeutic IV. Copyright

    Heart failure with mid-range left ventricular ejection fraction (HFmrEF) is a poorly characterized population as it has been studied either in the context of HF with reduced (HFrEF) or preserved (HFpEF) left ventricular ejection fraction (LVEF) depending on applied LVEF cutoffs. We sought to investigate the clinical profile, in-hospital management, and short-term outcome of HFmrEF patients in comparison with those with HFrEF or HFpEF in a large acute HF cohort. The Acute Heart Failure Global Registry of Standard Treatment (ALARM-HF) included 4953 patients hospitalized for HF in nine countries in Europe, Latin America, and Australia. Baseline characteristics, clinical presentation, in-hospital therapies, and short-term mortality (all-cause in-hospital or 30-day mortality, whichever first) were compared among HFrEF (LVEF chronic renal disease (p = 0.003), more hospitalizations for acute coronary syndrome (p < 0.001), or infection (p = 0.003), and were more frequently treated with intravenous vasodilators compared to HFrEF or HFpEF. Adjusted short-term mortality in HFmrEF was lower than HFrEF [hazard ratio (HR) = 0.635 (0.419, 0.963), p = 0.033] but similar to HFpEF [HR = 1.026 (0.605, 1.741), p = 0.923]. Hospitalized HFmrEF patients represent a demographically and clinically diverse group with many intermediate features compared to HFrEF and HFpEF and carry a lower risk of short-term mortality than HFrEF but a similar risk with HFpEF.

    The bioabsorbable poly-L-D-lactide joint scaffold arthroplasty is a recent attempt in the reconstruction of small joints in rheumatoid patients. In this study, we analysed the 1-year clinical, functional and radiologic results of partial trapeziectomy with the poly-L-D-lactide (96/4) joint scaffold in 23 patients with isolated trapeziometacarpal osteoarthritis. The results showed that the procedure provided pain relief and improvement in overall function according to the Quick Disabilities of the Arm, Shoulder and Hand score in most patients. However, radiographs demonstrated a high frequency of osteolysis around the implant. Seven patients developed clinically manifested foreign-body reactions 6 months to 1 year after surgery. The reason for the unexpected tissue reactions may relate to excessive mechanical cyclic loading of the implant. The outcomes of this implant in our patients have not been sufficiently beneficial and we have discontinued use of this implant in isolated trapeziometacarpal osteoarthritis. © The Author(s) 2015.

  12. A Good Short-term Outcome in Delayed Decompression of Cauda Equina Syndrome in Klebsiella pneumoniae Spinal Epidural Abscess: A Case Report

    2017-07-01

    Full Text Available Spinal epidural abscess is a severe, generally pyogenic, infection of the epidural space of spinal cord or cauda equina. The swelling caused by the abscess leads to compression or vascular disruption of neurological structures that requires urgent surgical decompression to avoid significant permanent disability. We share a rare case of Klebsiella pneumoniae spinal epidural abscess secondary to haematogenous spread of previous lung infection that presented late at our centre with cauda equina syndrome that showed good short-term outcome in delayed decompression. A 50-year old female presented with one-week history of persistent low back pain with progressively worsening bilateral lower limb weakness for seven days and urinary retention associated with saddle anesthesia of 2-day duration. Magnetic resonance imaging with contrast of the lumbo-sacral region showed an intramuscular collection of abscess at left gluteus maximus and left multifidus muscle with a L3-L5 posteriorly placed extradural lesion enhancing peripherally on contrast, suggestive of epidural abscess that compressed the cauda equina. The pus was drained using the posterior lumbar approach. Tissue and pus culture revealed Klebsiella pneumoniae, suggestive of bacterial infection. The patient made immediate improvement of muscle power over bilateral lower limbs postoperative followed by ability to control micturition and defecation in the 4th post-operative day. A good short-term outcome in delayed decompression of cauda equine syndrome is extremely rare. Aggressive surgical decompression combined with antibiotic therapy led to good short-term outcome in this patient despite delayed decompression of more than 48 hours.

    Intracerebral hemorrhage (ICH) is a common and severe form of stroke but is scarcely studied in young adults. Our aim was to study risk factors, clinical presentation and early mortality of ICH in the young and compare these features with older patients. All consecutive patients aged between 16 and 49 diagnosed with a first-ever ICH at the Departments of Neurology or Neurosurgery of the Helsinki University Central Hospital between January 2000 and March 2010 (n = 336) were analyzed retrospectively. Comparisons were performed amongst demographic subgroups and with patients over 49 years of age enrolled between January 2005 and March 2010 (n = 921). In the young patients, median age was 42 years (interquartile range 34-47), 59.5% were male, and annual incidence was 4.9 (95% confidence interval 4.5-5.3) per 100 000. The most prevalent risk factors were hypertension (29.8%) and smoking (22.3%). Compared with older patients hypertensive microangiopathy was less common (25.0% vs. 34.3%, P = 0.002) and structural lesions more common (25.0% vs. 4.9%, P young patients and in 22.5% of those who underwent magnetic resonance imaging and any angiography (n = 89, P = 0.023). Three-month mortality rate was lower in young patients compared with older ones (17.0% vs. 32.7%, P ages (P = 0.324) and independently predicted mortality in older patients but not in the young. Intracerebral hemorrhage (ICH) in the young appears less fatal and has a different spectrum of causes and factors associated with short-term mortality than for the elderly. © 2014 EAN.

    Numerous studies have described the use of biofeedback therapy for the treatment of anismus. Success rates vary widely, but few data are available regarding factors predictive of success. Our aim was to evaluate short-term results of biofeedback associated with diet in patients with obstructed defecation because of anismus and to investigate factors that may affect the results. Patients were identified from a single-institution prospectively maintained database. This study was conducted in a tertiary hospital. Consecutive patients who had obstructed defecation associated with anismus and were treated with biofeedback associated with diet were eligible. Each patient underwent anal manometry and/or dynamic anal ultrasound. Patients with anismus and were treated with biofeedback associated with diet. Patients classed as having a satisfactory response to therapy and those classed as having an unsatisfactory response were compared with regard to sex, age, Cleveland Clinic Florida constipation score, functional factors (anal resting and squeeze pressures and reversal of paradoxical puborectalis contraction on manometry), and anatomic factors in women (history of vaginal delivery, number of vaginal deliveries, menopause, hysterectomy, and previous anorectal surgery). A total of 116 patients were included (75 women and 41 men). Overall, 59% were classed as having a satisfactory response (decrease in constipation score, >50%). Patients with satisfactory responses to biofeedback plus diet did not differ from those with unsatisfactory responses with regard to clinical, anatomic, and physiological factors. This was not a randomized controlled trial. Biofeedback combined with diet is a valuable treatment option for patients with obstructed defecation syndrome associated with anismus, and more than half of our patients of both sexes achieved a satisfactory response. Improvement was not related to reversal of paradoxical contraction of puborectalis muscles at manometry. Patient

    Sleep deprivation (SD) impairs short-term memory, but it is unclear whether this is because of reduced storage capacity or processes contributing to appropriate information encoding. We evaluated 30 individuals twice, once after a night of normal sleep and again after 24 h of SD. In each session, we evaluated visual memory capacity by presenting arrays of one to eight colored squares. Additionally, we measured cortical responses to varying visual array sizes without engaging memory. The magnitude of intraparietal sulcus activation and memory capacity after normal sleep were highly correlated. SD elicited a pattern of activation in both tasks, indicating that deficits in visual processing and visual attention accompany and could account for loss of short-term memory capacity. Additionally, a comparison between better and poorer performers showed that preservation of precuneus and temporoparietal junction deactivation with increasing memory load corresponds to less performance decline when one is sleep-deprived.

    To know the prevalence of substance use and its relationship with psychopathology at onset and after six months in children and adolescents with first episode psychosis (FEP). 110 FEP patients, aged 9-17, were assessed for substance use, and with the Positive and Negative Syndrome Scale (PANSS) and other psychopathological and general functioning scales at baseline and after a six-month follow-up. Patients' substance use at baseline was: tobacco (30.9%), cannabis (29.1%), alcohol (21.8%), cocaine (8.2%), amphetamines (2.7%), LSD (1.8%) and opiates (0.90%). Six months later, there was a decrease in patients' use of cannabis (p=0.004) and other drugs, except tobacco. Patients were divided, according to their baseline cannabis use, into 32 cannabis users (CU) and 78 non-cannabis users (NCU). CU were older (p=0.002) and had higher PANSS positive scores (p=0.002) and lower PANSS negative (p<0.001), PANSS general (p=0.002) and PANSS total (p=0.007) scores than NCU. At six months, CU had significantly lower PANSS positive (p=0.010), negative (p=0.0001), general (p=0.002) and total (p=0.002) scores than NCU. When we divided CU at six months into previous CU (n=16) and current CU (n=15), previous CU had the best outcome, NCU the worst and current CU had an intermediate profile. Cannabis use may be related to higher positive symptom scores for FEP patients, with greater improvement after six months for those who cease using cannabis.

    Short-term exposure to ambient air pollution has been associated with lower pulmonary function and higher blood pressure (BP). However, controversy remains regarding the relationship between ambient multiple daily ozone (O 3 ) metrics and cardiopulmonary health outcomes, especially in the developing countries. To investigate and compare the short-term effects of various O 3 metrics on pulmonary function, fractional exhaled nitric oxide (FeNO) and BP in a panel study of COPD patients. We measured pulmonary function, FeNO and BP repeatedly in a total of 43 patients with COPD for 215 home visits. Daily hourly ambient O 3 concentrations were obtained from central-monitoring stations close to subject residences. We calculated various O 3 metrics [daily 1-h maximum (O 3 -1 h max), maximum 8-h average (O 3 -8 h max) and 24-h average (O 3 -24 h avg)] based on the hourly data. Daily indoor O 3 concentrations were estimated based on estimated indoor/outdoor O 3 ratios. Linear mixed-effects models were used to estimate associations of various O 3 metrics with cardiopulmonary function variables. An interquartile range (IQR) increase in ambient O 3 -8 h max (80.5 μg/m 3 , 5-d) was associated with a 5.9% (95%CI: -11.0%, -0.7%) reduction in forced expiratory volume in 1 s (FEV 1 ) and a 6.2% (95%CI: -10.9%, -1.5%) reduction in peak expiratory flow (PEF). However, there were no significant negative associations between ambient O 3 -1 h max, O 3 -24 h avg and FEV 1 , PEF. An IQR increase in ambient O 3 -1 h max (85.3 μg/m 3 , 6-d) was associated with a 6.7 mmHg (95%CI: 0.7, 12.7) increase in systolic BP. The estimated indoor O 3 were still significantly associated with reduction of FEV 1 and PEF. No significant associations were found between various O 3 metrics and FeNO. Our results provide clues for the adverse cardiopulmonary effects associated with various O 3 metrics in COPD patients and highlight that O 3 -8 h max was more closely associated with respiratory

    Full Text Available Abstract Background Effective pain management following total knee arthroplasty (TKA is fundamental in achieving positive rehabilitation outcomes. The purpose of our study was to investigate post operative pain management in relation to short term functional mobility in an intervention group receiving concomitant use of an IV narcotic PCA and a continuous infusion of local anaesthetic via a femoral nerve catheter (CFNC, compared to a group receiving narcotic PCA alone. This was a preliminary study conducted to establish an appropriate design for a larger investigative study. Methods A prospective design was used to measure the effect of a CFNC on post operative pain management and functional mobility prior to hospital discharge. The amount of fentanyl used, pain and nausea scores, timed up and go (TUG tests and active range of knee movement (AROM were used to compare a CFNC and supplemental narcotic patient controlled analgesia (PCA group (n = 27 with a PCA only group (n = 25. Results The CFNC group used significantly less fentanyl than the PCA only group (p s = .505 p s = .529 p s = .328, p = .034 Conclusions In this small preliminary study improved TUG performance at Day 4 post op was not influenced by the use of a CFNC but was positively correlated with male gender, preoperative performance, time elapsed since last oral analgesia and pain score. However AROM was decreased in the CFNC group suggesting further research on the relationship between CFNCs, local anaesthetic concentration and quadriceps strength should be incorporated in the follow up study's design.

  4. Self-reported strategies in decisions under risk: role of feedback, reasoning abilities, executive functions, short-term-memory, and working memory.

    In decisions under objective risk conditions information about the decision options' possible outcomes and the rules for outcomes' occurrence are provided. Thus, deciders can base decision-making strategies on probabilistic laws. In many laboratory decision-making tasks, choosing the option with the highest winning probability in all trials (=maximization strategy) is probabilistically regarded the most rational behavior. However, individuals often behave less optimal, especially in case the individuals have lower cognitive functions or in case no feedback about consequences is provided in the situation. It is still unclear which cognitive functions particularly predispose individuals for using successful strategies and which strategies profit from feedback. We investigated 195 individuals with two decision-making paradigms, the Game of Dice Task (GDT) (with and without feedback), and the Card Guessing Game. Thereafter, participants reported which strategies they had applied. Interaction effects (feedback × strategy), effect sizes, and uncorrected single group comparisons suggest that feedback in the GDT tended to be more beneficial to individuals reporting exploratory strategies (e.g., use intuition). In both tasks, the self-reported use of more principled and more rational strategies was accompanied by better decision-making performance and better performances in reasoning and executive functioning tasks. The strategy groups did not significantly differ in most short-term and working-memory tasks. Thus, particularly individual differences in reasoning and executive functions seem to predispose individuals toward particular decision-making strategies. Feedback seems to be useful for individuals who rather explore the decision-making situation instead of following a certain plan.

    Total knee arthroplasty (TKA) and total hip arthroplasty (THA) are common and effective surgical procedures. This study sought to compare utilization and short-term outcomes of primary TKA and THA in adjacent regions of Canada and the United States. The study was designed as a retrospective cohort study of patients who underwent primary TKA or THA, comparing administrative data from New York and Ontario in 2012-2013. Demographic features of the TKA and THA patients, per capita utilization rates, and short-term outcomes were compared between the jurisdictions.

    Colorectal cancer (CRC) is the third most common cancer worldwide. Although laparoscopic-assisted complete mesocolic excision (LCME) is a superior treatment, there are few studies available on it owe to the low incidence and technical difficulty of LCME in transverse colon cancer. The clinical data of 78 patients with transverse colon cancer who were treated by LCME and open complete mesocolic excision (OCME) were retrospectively analyzed. A total of 39 cases had been treated by LCME, compared with 39 cases treated by OCME. The patient characteristics and short-term outcomes including operation time, intra-operative blood loss, length of incision, time to first flatus, first postoperative ambulation, postoperative hospitalization time, number of harvested lymph nodes, length of resected specimen and incidence of complications were evaluated. There was no case converted to OCME in LCME group. LCME had significantly shorter length of incision, shorter operation time, less intra-operative blood loss, shorter postoperative hospitalization time (Pcolon cancer due to it can provide superior short-term outcomes including less intra-operative blood loss, faster recovery and lower incidence of wound infection.

    To compare the perioperative outcomes associated with open and laparoscopic (LAP) surgical approaches for liver metastases. The American College of Surgeons National Surgical Quality Improvement Program database was used to identify all adult patients who underwent surgical therapy for metastatic liver tumors between 2006 and 2012 (N=7684). Patients who underwent >1 procedure were excluded. Logistic regression after matching on propensity scores was used to assess the association between surgical approaches and perioperative outcomes. A total of 4555 patients underwent open resection, 387 LAP resection, 297 open radiofrequency ablation (RFA), and 265 LAP RFA. In propensity-matched samples (over 95% of patients successfully matched), there was no significant difference between LAP resection and LAP RFA in perioperative complications and length of stay and both compared favorably with their open counterparts. Minimally invasive approaches for secondary hepatic malignancies were associated with improved postoperative morbidity and length of stay and should be preferred in appropriate patients.

    Improving primary care for chronic disease management requires a coherent, integrated approach to quality improvement. Evidence in the continuing professional development (CPD) field suggests the importance of using strategies such as feedback delivery, reflective practice and action planning to facilitate recognition of gaps and service improvement needs. Our study explored the outcomes of a CPD intervention, named the COMPAS Project, which consists of a three-hour workshop composed of three main activities: feedback, critical reflection and action planning. The feedback intervention is delivered face-to-face and presents performance indicators extracted from clinical-administrative databases. This aim of this study was to assess the short term outcomes of this intervention to engage primary care professional in continuous quality improvement (QI). In order to develop an understanding of our intervention and of its short term outcomes, a program evaluation approach was used. Ten COMPAS workshops on diabetes management were directly observed and qualitative data was collected to assess the intervention short term outcomes. Data from both sources were combined to describe the characteristics of action plans developed by professionals. Two independent coders analysed the content of these plans to assess if they promoted engagement in QI and interprofessional collaboration. During the ten workshops held, 26 interprofessional work teams were formed. Twenty-two of them developed a QI project they could implement themselves and that targeted aspects of their own practice they perceived in need of change. Most frequently prioritized strategies for change were improvement of systematic clientele follow-up, medication compliance, care pathway and support to improve adoption of healthier life habits. Twenty-one out of 22 action plans were found to target some level of improvement of interprofessional collaboration in primary care. Our study results demonstrate that the

    Improvements in immunosuppression have modified short-term survival of deceased-donor allografts, but not their rate of long-term failure. Mismatches between donor and recipient HLA play an important role in the acute and chronic allogeneic immune response against the graft. Perfect matching at clinically relevant HLA loci does not obviate the need for immunosuppression, suggesting that additional genetic variation plays a critical role in both short- and long-term graft outcomes. By combining patient data and samples from supranational cohorts across the United Kingdom and European Union, we performed the first large-scale genome-wide association study analyzing both donor and recipient DNA in 2094 complete renal transplant-pairs with replication in 5866 complete pairs. We studied deceased-donor grafts allocated on the basis of preferential HLA matching, which provided some control for HLA genetic effects. No strong donor or recipient genetic effects contributing to long- or short-term allograft survival were found outside the HLA region. We discuss the implications for future research and clinical application. © 2018 The Authors.

    To evaluate risk factors associated with death and development of perioperative complications in dogs undergoing surgery for treatment of gastric dilatation-volvulus (GDV). Retrospective case series. 166 dogs. Records of dogs with confirmed GDV that underwent surgery were reviewed. Logistic regression was performed to identify factors associated with development of complications (ie, hypotension, arrhythmias, gastric necrosis necessitating gastrectomy, disseminated intravascular coagulation, peritonitis, sepsis, postoperative dilatation, postoperative vomiting, and incisional problems) and with short-term outcome (ie, died vs survived to the time of suture removal). Short-term mortality rate was 16.2% (27/166). Risk factors significantly associated with death prior to suture removal were clinical signs for > 6 hours prior to examination, combined splenectomy and partial gastrectomy, hypotension at any time during hospitalization, peritonitis, sepsis, and disseminated intravascular coagulation. Partial gastrectomy was not a significant risk factor for death but was for peritonitis, disseminated intravascular coagulation, sepsis, and arrhythmias. Age, gastrectomy, and disseminated intravascular coagulation were risk factors for development of hypotension. Use of a synthetic colloid or hypertonic saline solution was associated with a significantly decreased risk of hypotension. Results suggest that the prognosis for dogs undergoing surgery because of GDV is good but that certain factors are associated with an increased risk that dogs will develop perioperative complications or die.

    To develop a reliable coding scheme for components of group-based behavioral support for smoking cessation, to establish the frequency of inclusion in English Stop-Smoking Service (SSS) treatment manuals of specific components, and to investigate the associations between inclusion of behavior change techniques (BCTs) and service success rates. A taxonomy of BCTs specific to group-based behavioral support was developed and reliability of use assessed. All English SSSs (n = 145) were contacted to request their group-support treatment manuals. BCTs included in the manuals were identified using this taxonomy. Associations between inclusion of specific BCTs and short-term (4-week) self-reported quit outcomes were assessed. Fourteen group-support BCTs were identified with >90% agreement between coders. One hundred and seven services responded to the request for group-support manuals of which 30 had suitable documents. On average, 7 BCTs were included in each manual. Two were positively associated with 4-week quit rates: "communicate group member identities" and a "betting game" (a financial deposit that is lost if a stop-smoking "buddy" relapses). It is possible to reliably code group-specific BCTs for smoking cessation. Fourteen such techniques are present in guideline documents of which 2 appear to be associated with higher short-term self-reported quit rates when included in treatment manuals of English SSSs.

Methods: The study designed as a retrospective observational analysis and was set in a single tertiary center. Eighty-nine patients (89 eyes with NVG, were treated using trabeculectomy alone (Trab group; n=39 or EX-PRESS implantation (EX group; n=50. All patients with a history of glaucoma surgery were excluded. The main outcome measures were postoperative intraocular pressure (IOP, visual acuity (VA, number of medications, complications, additional therapy, and success rate. Results: The mean follow-up duration was 4.6 months in the Trab group and 4.2 months in the EX group. There was no significant difference in IOP between the groups except at 1-month follow-up (P=0.045. The number of patients with early postoperative hypotony, a shallow anterior chamber, hyphema, or anterior chamber irrigation was significantly lower in the EX group than in the Trab group (P=0.016, 0.008, 0.019, and 0.014, respectively. The other outcomes, ie, VA, number of medications, and success rate, were similar between the two groups. In the EX group, the success rate was significantly lower in 15 patients with a history of vitrectomy compared to that in 35 patients without a history of vitrectomy (P=0.047. Conclusion: Implantation of an EX-PRESS device may be more effective and safer than trabeculectomy alone in patients with NVG. However, a history of vitrectomy may affect the surgical success rate when using EX-PRESS. Keywords: trabeculectomy, EX-PRESS, neovascular glaucoma, surgery, tube shunt

    Full Text Available Gastrointestinal stromal tumors are the most common mesenchymal neoplasms of the gastrointestinal tract. Recently, many studies have addressed the laparoscopic management of these tumors. The aim of this study was to evaluate the safety and efficacy of laparoscopic atypical gastrectomy in the resolution of these neoplasms. In the period between January 2009 and December 2015, 24 patients with suspected gastric GIST less than 5 cm in size underwent surgery under this approach. Abscense of peritoneal and liver metastases and immunohistochemistry expression of CD117 antigen were considered as inclusion criteria. We retrospectively analyzed clinical and histopathological characteristics, surgical outcomes, postoperative complications and oncological results. Statistical analysis included 14 patients. The mean age was 60 years (10 women and 4 men and upper gastrointestinal bleeding was the chief complaint for consultation. Conversion to open surgery was necessary in one case and no major complications, readmissions or reoperations were recorded. The mean tumor size was 41 mm with negative resection margin in all samples. The mean hospital stay was 3 days and no tumor recurrences were recorded in 44 months of follow-up. Laparoscopic atypical gastrectomy for gastric GIST is a safe and effective technique with good outcomes in experienced hands

    The study aims to investigate the role of {sup 18}F-alfatide positron emission tomography/computed tomography (PET/CT) in predicting the short-term outcome of concurrent chemoradiotherapy (CCRT) in patients with advanced non-small cell lung cancer (NSCLC). Eighteen patients with advanced NSCLC had undergone {sup 18}F-alfatide PET/CT scans before CCRT and PET/CT parameters including maximum and mean standard uptake values (SUV{sub max}/SUV{sub mean}), peak standard uptake values (SUV{sub peak}) and tumor volume (TV{sub PET} and TV{sub CT}) were obtained. The SUV{sub max} of tumor and normal tissues (lung, blood pool and muscle) were measured, and their ratios were denoted as T/NT (T/NT{sub lung}, T/NT{sub blood} and T/NT{sub muscle}). Statistical methods included the Two-example t test, Wilcoxon rank-sum test, Receiver-operating characteristic (ROC) curve analysis and logistic regression analyses. We found that SUV{sub max}, SUV{sub peak}, T/NT{sub lung}, T/NT{sub blood} and T/NT{sub muscle} were higher in non-responders than in responders (P = 0.0024, P = 0.016, P < 0.001, P = 0.003, P = 0.004). According to ROC curve analysis, the thresholds of SUV{sub max}, SUV{sub peak}, T/NT{sub lung}, T/NT{sub blood} and T/NT{sub muscle} were 5.65, 4.46, 7.11, 5.41, and 11.75, respectively. The five parameters had high sensitivity, specificity and accuracy in distinguishing non-responders and responders. Multivariate logistic regression analyses showed that T/NT{sub lung} was an independent predictor of the short-term outcome of CCRT in patients with advanced NSCLC (P = 0.032). {sup 18}F-alfatide PET/CT may be useful in predicting the short-term outcome of CCRT in patients with advanced NSCLC.

    This is a rather bold attempt to bridge the gap between neuron structure and psychological data. We try to answer the question: Is there a relation between the neuronal connectivity in the human cortex (around 5,000) and the short-term memory capacity (7±2)? Our starting point is the Hopfield model (Hopfield 1982), presented in this volume by D.J. Amit.

    Summary Background International research for acute myocardial infarction lacks comparisons of whole health systems. We assessed time trends for care and outcomes in Sweden and the UK. Methods We used data from national registries on consecutive patients registered between 2004 and 2010 in all hospitals providing care for acute coronary syndrome in Sweden and the UK. The primary outcome was all-cause mortality 30 days after admission. We compared effectiveness of treatment by indirect casemix standardisation. This study is registered with ClinicalTrials.gov, number NCT01359033. Findings We assessed data for 119 786 patients in Sweden and 391 077 in the UK. 30-day mortality was 7·6% (95% CI 7·4–7·7) in Sweden and 10·5% (10·4–10·6) in the UK. Mortality was higher in the UK in clinically relevant subgroups defined by troponin concentration, ST-segment elevation, age, sex, heart rate, systolic blood pressure, diabetes mellitus status, and smoking status. In Sweden, compared with the UK, there was earlier and more extensive uptake of primary percutaneous coronary intervention (59% vs 22%) and more frequent use of β blockers at discharge (89% vs 78%). After casemix standardisation the 30-day mortality ratio for UK versus Sweden was 1·37 (95% CI 1·30–1·45), which corresponds to 11 263 (95% CI 9620–12 827) excess deaths, but did decline over time (from 1·47, 95% CI 1·38–1·58 in 2004 to 1·20, 1·12–1·29 in 2010; p=0·01). Interpretation We found clinically important differences between countries in acute myocardial infarction care and outcomes. International comparisons research might help to improve health systems and prevent deaths.

    The Danish Shoulder Arthroplasty Registry (DSR) was established in 2004. Data are reported electronically by the surgeons. Patient-reported outcome is collected 10-14 months postoperatively using the Western Ontario osteoarthritis of the shoulder index (WOOS). 2,137 primary shoulder arthroplasties...... (70% women) were reported to the registry between January 2006 and December 2008. Mean age at surgery was 69 years (SD 12). The most common indications were a displaced proximal humeral fracture (54%) or osteoarthritis (30%). 61% were stemmed hemiarthroplasties, 28% resurfacing hemiarthroplasties, 8......% reverse shoulder arthroplasties, and 3% total arthroplasties. Median WOOS was 59% (IQR: 37-82). 5% had been revised by the end of June 2010. The most frequent indications for revision were dislocation or glenoid attrition....

    This study aims to describe patient demographics, visual and surgical outcomes of a cohort undergoing small incision cataract surgery at a Pacific regional ophthalmic training facility. This is a prospective, longitudinal study conducted at the Pacific Eye Institute, Fiji. One hundred fifty-six patients underwent small incision cataract surgery. Preoperatively, a complete ophthalmic examination, including pachymetry and macular optical coherence tomography performed by two independent investigators. Temporal small incision cataract surgery with intraocular lens insertion was performed by ophthalmologists, and trainee ophthalmologists. Follow-up occurred at day one, four weeks and 3 months. Patient characteristics, visual outcomes including surgically induced astigmatism and complications. Ninety-one per cent (142/156) attended 3-month follow-up with median age 63 years (range 19-82), 52% female (81/156) and 58% (90/156) Fijian ethnicity. In 37% (57/156), the contralateral eye was pseudophakic. Mean preoperative best spectacle-corrected visual acuity was logMAR 1.44 (6/165). At 3 months, 74% (105/142) achieved ≥6/18 unaided vision (94% [133/142] best spectacle-corrected visual acuity). Mean postoperative spherical equivalent was -0.78 (SD 0.95) D and mean surgically induced astigmatism 1.04 (0.57) D. Complications included posterior capsular rupture with vitreous loss (4% [6/156]), optical coherence tomography confirmed macular oedema (8% [12/152] at 4 weeks), significant posterior capsular opacity (23% [31/136]) and >5% increase in preoperative pachymetry (1% [1/142]) at 3 months. Reduction in preoperative best spectacle-corrected visual acuity occurred in 2% (3/142). No cases of endophthalmitis. Small incision cataract surgery provided to a regional population is effective with 94% achieving the World Health Organisation's definition of 'Good Vision' (≥6/18). Refinements in biometric and surgical techniques may allow a greater proportion of patients to

    OBJECTIVES: to evaluate specialist geriatric input and medication review in patients in high-dependency continuing care. DESIGN: prospective, randomised, controlled trial. SETTING: two residential continuing care hospitals. PARTICIPANTS: two hundred and twenty-five permanent patients. INTERVENTION: patients were randomised to either specialist geriatric input or regular input. The specialist group had a medical assessment by a geriatrician and medication review by a multidisciplinary expert panel. Regular input consisted of review as required by a medical officer attached to each ward. Reassessment occurred after 6 months. RESULTS: one hundred and ten patients were randomised to specialist input and 115 to regular input. These were comparable for age, gender, dependency levels and cognition. After 6 months, the total number of medications per patient per day fell from 11.64 to 11.09 in the specialist group (P = 0.0364) and increased from 11.07 to 11.5 in the regular group (P = 0.094). There was no significant difference in mortality or frequency of acute hospital transfers (11 versus 6 in the specialist versus regular group, P = 0.213). CONCLUSION: specialist geriatric assessment and medication review in hospital continuing care resulted in a reduction in medication use, but at a significant cost. No benefits in hard clinical outcomes were demonstrated. However, qualitative benefits and lower costs may become evident over longer periods.

    Background: We present outcomes of Ahmed Glaucoma Valve (AGV) implantation in treating refractory glaucoma in a tertiary hospital in Oman. Refractory glaucoma was defined as previously failed conventional glaucoma surgery and an uncontrolled intraocular pressure (IOP) of more than 21 mm Hg despite treatment with three topical and/or oral therapy. Materials and Methods: This historical cohort study was conducted in 2010. Details of medical and surgical treatment were recorded. Ophthalmologists examined eyes and performed glaucoma surgeries using AGV. The best corrected distant vision, IOP, and glaucoma medications were prospectively reviewed on 1st day, 1st, 6th, 12th week postoperatively, and at the last follow up. Result: Glaucoma specialists examined and treated 40 eyes with refractory glaucoma of 39 patients (20 males + 19 females). Neo-vascular glaucoma was present in 23 eyes. Vision before surgery was glaucoma medications (2.38; SD 1.1) was reduced compared to the mean number of postoperative medications (1.92; SD 0.9) at 12 weeks. Conclusion: We succeeded in reducing visual disabilities and the number of anti-glaucoma medications used to treat refractory glaucoma by AGV surgery. PMID:23772122

    Convulsive status epilepticus is the most common childhood neurological emergency in developing countries, where poor healthcare organisation could play a negative role in the management of the condition. Unavailability of second-line injectable anticonvulsants is an additional hindering factor in Georgia. This report reflects the results of the first study aimed at evaluating the epidemiological features of convulsive status epilepticus, as well as identifying obstacles influencing the management of patients with convulsive status epilepticus in Georgia. A prospective, hospital-based study was performed. Paediatric patients with convulsive status epilepticus, admitted to the emergency department of a referral academic hospital from 2007 to 2012, were included in the study. Forty-eight paediatric patients admitted to hospital met the criteria for convulsive status epilepticus. Seizure duration was significantly shorter among the group with adequate and timely pre-hospital intervention. Moreover, patients with appropriate pre-hospital treatment less frequently required mechanical ventilation (p=0.039). Four deaths were detected during the follow-up period, thus the case fatality rate was 8%. Only 31% of patients received treatment with intravenous phenytoin. The study results show that adequate and timely intervention could improve outcome of convulsive status epilepticus and decrease the need for mechanical ventilation. Mortality parameters were comparable to the results from other resource-limited countries. More than one third of patients did not receive appropriate treatment due to unavailability of phenytoin.

    Minimally invasive techniques for gastric cancer surgery have recently been introduced in the Netherlands, based on a proctoring program. The aim of this population-based cohort study was to evaluate the short-term oncological outcomes of minimally invasive gastrectomy (MIG) during its introduction in the Netherlands. The Netherlands Cancer Registry identified all patients with gastric adenocarcinoma who underwent gastrectomy with curative intent between 2010 and 2014. Multivariable analysis was performed to compare MIG and open gastrectomy (OG) on lymph node yield (≥15), R0 resection rate, and 1-year overall survival. The pooled learning curve per center of MIG was evaluated by groups of five subsequent procedures. Between 2010 and 2014, a total of 277 (14%) patients underwent MIG and 1633 (86%) patients underwent OG. During this period, the use of MIG and neoadjuvant chemotherapy increased from 4% to 39% (p introduction of minimally invasive gastrectomy in Western countries is feasible and can be performed safely.

    While the relevance of falls in raising the risk of fractures, hospitalization and disability in older age is well recognized, the factors influencing the onset of fractures and the need for ward admission after a fall have yet to be fully elucidated. We investigated which factors and fall dynamics were mainly associated with fall-related injuries and hospitalization among elderly persons accessing the Emergency Department (ED) following a fall. The study involved 2144 older subjects who accessed the ED after a fall. Data on the fall´s nature and related injuries, ward admissions, history of falls, dementia, and medical therapies were examined for all patients. Considering dynamics, we distinguished accidental falls (due to interaction with environmental hazards while in motion) and falls from standing (secondary to syncope, lipothymia, drop attack, or vertigo). The overall prevalence of fractures in our population did not differ significantly with advancing age, though hip fractures were more common in the oldest, and upper limb fractures in the youngest patients. Falls from standing were associated with polypharmacy and with higher ward admission rate despite a lower fractures´ prevalence than accidental falls. The chances of fall-related fractures were more than fourfold as high for accidental dynamics (OR=4.05, 95%CI:3.10-5.29, pfall-related fractures (OR=6.84, 95%CI:5.45-8.58, pfall dynamics. Outcomes of falls in older age depend not only on any fall-related injuries, but also on factors such as polypharmacy, cognitive status and fall dynamics. Copyright © 2017 Elsevier B.V.

    The TVT-Secur (Ethicon, Somerville, NJ, USA) is a minimally invasive suburethral synthetic sling used in the treatment of female stress urinary incontinence. It claims to cause less postoperative pain and to enable performing in an office setting. However, this may be at the expense of a significant learning curve and a higher early failure rate. To assess objectively the success rate of the TVT-Secur procedure in the 'U' configuration at six months. Secondary outcomes focussed on subjective success rates, complications, patient satisfaction and quality-of-life (QOL). A prospective observational study was undertaken at two tertiary referral urogynaecology centres. A cohort of 42 consecutive patients with urodynamic stress incontinence who underwent the TVT-Secur procedure in the 'U' configuration between November 2006 and August 2007 were followed up for six months. Three standardised QOL questionnaires were completed preoperatively and at six months. A urogenital history, visual analogue score (VAS) for patient satisfaction, uroflow and urinary stress test were performed at six months. Recruitment was ceased prematurely because of a high number of early failures. Objective and subjective success rates at six months were 58.3% and 51.3% respectively. Complications included urinary tract infections, voiding difficulty, groin discomfort, haematoma, vaginal pain, tape erosion and intra-operative dislodgement of tape. Prevalence of de novo urge incontinence was 10.3%. Only symptom-specific QOL scores improved and only 48.6% indicated a high level satisfaction (VAS > or = 80%) with TVT-Secur. On the basis of this limited study, we are hesitant to recommend the 'U' configuration of the TVT-Secur over its more established counterparts, the TVT and TVT-O.

    Total or proximal gastrectomy is usually performed for early proximal gastric carcinoma, but the optimal type of gastrectomy is still unknown. We evaluated short-term outcomes and nutritional status after laparoscopic subtotal gastrectomy (LsTG) in comparison with laparoscopic total gastrectomy (LTG) and laparoscopic proximal gastrectomy (LPG). We analyzed 113 patients who underwent LsTG (n = 38), LTG (n = 48), or LPG (n = 27) for cStage I gastric cancer located in the upper third of the stomach. Postoperative morbidities, nutritional status including body weight, serum albumin, hemoglobin, the prognostic nutritional index (PNI), and endoscopic findings at 1 year after surgery were compared between LsTG and both LTG and LPG. Operation time and intraoperative blood loss were similar among the three groups. The incidence of postoperative morbidities was lower in LsTG than in LTG. The degree of body weight loss was significantly smaller in LsTG than in LTG at 6 and 12 months. At 12 months, LsTG resulted in better serum albumin and PNI than LPG, and better hemoglobin than LTG. Endoscopic examination demonstrated that one LsTG patient and two LPG patients had reflux esophagitis. Remnant gastritis was observed more frequently in LPG than in LsTG. No LsTG patient had bile reflux, although it was observed in four LPG patients. LsTG with a very small remnant stomach had favorable short-term outcomes and nutritional status compared with LTG and LPG, so it may be a better treatment option for cStage I proximal gastric carcinoma.

    Caffeine is effective in the treatment of apnea of prematurity but it is not well known if the therapeutic concentration of the drug has an impact on other neonatal outcomes such as chronic lung disease (CLD). The aim of this study was to determine if there is an association between caffeine concentrations and the incidence of CLD in premature infants of ⩽29 weeks of gestation. A retrospective chart review of all the infants born ⩽29 weeks of gestation from 2007 to 2011, who survived until discharge or 36 weeks postmenstrual age, was conducted. Caffeine concentrations were obtained weekly on infants getting the drug. Average caffeine concentrations (ACCs) were determined for the duration of caffeine therapy and correlated with CLD, length of stay (LOS), oxygen at discharge (OD), duration of ventilation (DV) and total charges for hospitalization for each patient. Of the 222 eligible infants, 198 met the inclusion criteria. ACC for infants without CLD was 17.0±3.8 μg ml(-1) compared with infants with CLD 14.3±6.1 μg ml(-1) (P14.5 μg ml(-1)) had lower incidence of patent ductus arteriosus, lesser number of days on ventilator and oxygen, lesser need for diuretics, lower incidence of CLD, were more likely to go home without supplemental OD and had lower LOS and lower total hospital charges (all differences were significant PCLD. Receiver operating curve analysis confirmed a significant predictive ability of caffeine concentration for CLD with a cutoff concentration of 14.5 μg ml(-1) (sensitivity of 42.6 and specificity of 86.8). The AUC (area under the curve) for the prediction of CLD was 0.632 (95% confidence interval 0.56-0.69, P=0.009). Caffeine concentrations >14.5 μg ml(-1) were strongly correlated with reduced CLD in infants born at ⩽29 weeks of gestation. Higher caffeine concentrations were associated with decreased total hospital charges, DV, OD and LOS. Additional randomized trials are needed to confirm these findings, to

    for pain showed similar results. Pain at admission was also related to age, calcification size, ultrasound and Gärtner score, power Doppler positivity, bursal wall thickening and biceps tenosynovitis. The success of the procedure with quick improvement in function and symptoms is warranted in soft and middle-sized calcifications, in young adults. Ultrasound-guided percutaneous procedures for RCCT must be safe, effective and with prompt pain relief and function restoration. This study shows which clinical picture is more favourable to this purpose and actual prognostic factors for DNL (soft and middle-sized calcifications, in young adults, are more favourable).

    Attention deficit/hyperactivity disorder (ADHD) is a common behavioral disorder found mainly in males, thus current knowledge on its clinical expression in female adults is extremely limited. AIM. To evaluate the behavioral and neural substrates associated with the performance of a short-term memory task in female ADHD adults, with and without methylphenidate exposure, with respect to a control group. Two groups of eight young right-handed, female, university students with ADHD and healthy controls matched by age, gender, handedness and academic level, voluntarily participated. All subjects performed twice an easy auditory short-term memory task (ADHD group without, and 90 minutes post-intake of methylphenidate 0.4 mg/kg in a counterbalanced order). The BOLD-fMRI response was used as a measure of neural activity during task performance. ADHD subjects showed a tendency to improve their performances under medication, showing an increased widespread functional activation, especially relevant over left frontal and cerebellar areas, in comparison with control subjects. Methylphenidate slightly improves short-term memory task performance in adult female ADHD subjects by modifying underlying neural functioning patterns.

    A number of exercises to strengthen the upper extremities are recommended to increase functional independence and quality of life (QoL) in patients with paraplegia. Circuit resistance training (CRT) is a type of progressive resistive exercise performed repeatedly at fixed mechanical exercise stations. The aim of this study was to investigate the potential benefits of CRT for upper extremity muscle strength, functional independence, and QoL in patients with paraplegia. Twenty-six patients with paraplegia who were participating in a conventional rehabilitation program at a tertiary education and research hospital were enrolled in this study. The participants were randomly assigned to two groups. The exercise group participated in the CRT program, which consisted of repetitive exercises for the upper extremities performed at fixed mechanical stations 5 sessions per week for 6 weeks, in addition to conventional rehabilitation. Participants in the control group received only conventional rehabilitation over the same period. We compared the groups with respect to QoL, as well as isokinetic muscle test outcomes in the upper extremities, using the Functional Independence Measure (FIM) and Borg's scale. We observed significant increases in scores on the physical component of the FIM, Borg's scale, and QoL in both the exercise and control groups. Furthermore, the large majority of isokinetic values were significantly more improved in the exercise group compared to the control group. When post-treatment outcomes were compared between the groups, improvements in scores on the physical component of the FIM and in most isokinetic values were significantly greater in the exercise group. This study showed that CRT has positive effects on muscle strength in the upper extremities and the physical disability components of the FIM when added to conventional rehabilitation programs for paraplegic patients. However, we observed no significant improvement in QoL scores after adding CRT

    Previous randomized controlled trials demonstrated similar oncological outcomes between laparoscopic and open colectomies, except for cases involving transverse colon and splenic flexure colon cancer. The objective of this study was to confirm the oncological safety and advantages of the short-term results of laparoscopic surgery for transverse and descending colon cancer in comparison with open surgery. The study data were retrospectively collected from the databases of 45 hospitals. Patients with transverse or descending colon cancer who underwent laparoscopic or open R0 resection were registered. The primary end-points were the 3-year overall survival and relapse-free survival rates according to pathological stage. The secondary end-points were the short-term results, including blood loss, operative time, diet intake, hospital stay, and postoperative complications. Of the 1830 eligible patients, 872 underwent open colectomy and 958 underwent laparoscopic colectomy. The median follow-up period was 38.4 months. The conversion rate to open resection was 4.5%. The 3-year overall survival rate of the laparoscopic group was significantly higher than that of the open group for stage I patients (96.2% vs 99.2%; P = 0.04); it was also higher for stage II (94.0% vs 95.5%) and stage III (87.4% vs 90.2%) patients, but there were no significant differences. The 3-year relapse-free survival rate of the laparoscopic group was significantly higher than that of the open group for stage I patients; there were no differences between the open and laparoscopic groups among the stage II and III patients. In the multivariate analyses, laparoscopic resection was a significant factor in relapse-free survival. Laparoscopic patients had significantly lower blood loss and a significantly longer operative time than the open groups. Also, postoperative hospital stay was significantly shorter and postoperative morbidity was significantly lower in the laparoscopic group. Although this

    In this retrospective study, we sought to delineate the collateral circulation status of acute ischemic stroke patients by CT perfusion and evaluate 90-day modified Rankin Scale (mRS) scores of patients with good or poor collaterals and its correlation with admission fasting plasma glucose (FPG). We enrolled acute ischemic stroke patients who presented to our hospital 4.5 h within an onset of the first episode between January 2009 and December 2015. Neurological assessment was performed using the 90-day mRS scores (0-2 for a favorable and 3-6 for an unfavorable neurologic outcome). Relative filling time delay (rFTD) was evaluated by CT perfusion scan. The primary outcomes were 90-day mRS scores stratified by good (rFTD ≤ 4 s) versus poor collateral circulation (rFTD > 4 s). Totally 270 patients were included, and 139 (51.5%) patients achieved a favorable neurologic outcome. One hundred eighty-five (68.5%) patients had good collateral circulation. Significantly greater portions of patients with good collateral circulation (60.5%, 112/185) achieved a favorable neurologic outcome compared to those with poor collateral circulation (31.8%, 27/85) (P collateral circulation achieving a favorable neurologic outcome had significantly lower baseline FPG (6.6 ± 1.96) than those with good collateral circulation achieving an unfavorable neurologic outcome (8.12 ± 4.02; P = 0.002). Spearman correlation analysis showed that rFTD significantly correlated with 90-day mRS scores (adjusted r = 0.258; P collateral circulation. FPG and rFTD may serve as useful predictors of short-term patient outcome and could be used for risk stratification in clinical decision making.

    Boron (B) is an essential plant nutrient, but when present in excess it is toxic. Morphological measurements were made to assess the impact of B toxicity on the growth of two different tomato hybrids, Losna and Ikram. Contrasting long and short-term B responses in these tomato hybrids, were observed. Losna showed less toxicity symptoms, maintaining higher growth and showing much less B content in both root and shoot tissues compared to Ikram. Root morphological differences did not explain the tolerance between the two hybrids. Under excess B supply, a significant inhibition on net nitrate uptake rate was observed in Ikram, but not in Losna. This effect may be explained by a decrease of nitrate transporter transcripts in Ikram, which was not measured in Losna. There was a different pattern of B transporter expression in two tomatoes and this can explain the contrasting tolerance observed. Indeed, Losna may be able to exclude or efflux B resulting in less accumulation in the shoot. Particularly, SlBOR4 expression showed significant differences between the tomato hybrids, with higher expression in Losna explaining the improved B-tolerance. Copyright © 2016 Elsevier Masson SAS.

    Children with nonorganic voice disorders (NVDs) are treated mainly using direct voice therapy techniques such as the accent method or glottal attack changes and indirect methods such as vocal hygiene and voice education. However, both approaches tackle only the symptoms and not etiological factors in the family dynamics and therefore often enjoy little success. The aim of the "Bernese Brief Dynamic Intervention" (BBDI) for children with NVD was to extend the effectiveness of pediatric voice therapies with a psychosomatic concept combining short-term play therapy with the child and family dynamic counseling of the parents. This study compares the therapeutic changes in three groups where different procedures were used, before intervention and 1 year afterward: counseling of parents (one to two consultations; n = 24), Brief Dynamic Intervention on the lines of the BBDI (three to five play therapy sessions with the child plus two to four sessions with the parents; n = 20), and traditional voice therapy (n = 22). A Voice Questionnaire for Parents developed by us with 59 questions to be answered on a four-point Likert scale was used to measure the change. According to the parents' assessment, a significant improvement in voice quality was achieved in all three methods. Counseling of parents (A) appears to have led parents to give their child more latitude, for example, they stopped nagging the child or demanding that he/she should behave strictly by the rules. After BBDI (B), the mothers were more responsive to their children's wishes and the children were more relaxed and their speech became livelier. At home, they called out to them less often at a distance, which probably improved parent-child dialog. Traditional voice therapy (C) seems to have had a positive effect on the children's social competence. BBDI seems to have the deepest, widest, and therefore probably the most enduring therapeutic effect on children with NVD. Copyright © 2013 The Voice Foundation

    To retrospectively evaluate the short-term outcomes and safety of computed tomography (CT)-guided percutaneous microwave ablation (MWA) of solitary adrenal metastasis from lung cancer. From May 2010 to April 2014, 31 patients with unilateral adrenal metastasis from lung cancer who were treated with CT-guided percutaneous MWA were enrolled. This study was conducted with approval from local Institutional Review Board. Clinical outcomes and complications of MWA were assessed. Their tumors ranged from 1.5 to 5.4 cm in diameter. After a median follow-up period of 11.1 months, primary efficacy rate was 90.3% (28/31). Local tumor progression was detected in 7 (22.6%) of 31 cases. Their median overall survival time was 12 months. The 1-year overall survival rate was 44.3%. Median local tumor progression-free survival time was 9 months. Local tumor progression-free survival rate was 77.4%. Of 36 MWA sessions, two (5.6%) had major complications (hypertensive crisis). CT-guided percutaneous MWA may be fairly safe and effective for treating solitary adrenal metastasis from lung cancer.

    Purpose To assess the potential effects of short-term exposure to particulate air pollution during follicular phase on clinical, laboratory, and pregnancy outcomes of women undergoing IVF/ET. Methods Retrospective cohort study of 400 first IVF/ET cycles of women exposed to ambient particulate matter during follicular phase. Particulate matter (PM) was categorized into quartiles (Q1: ≤30.48 µg/m3, Q2: 30.49–42.00 µg/m3, Q3: 42.01–56.72 µg/m3, and Q4: >56.72 µg/m3). Results Clinical, laboratory, or treatment variables were not affected by follicular phase PM exposure periods. Women exposed to Q4 period during the follicular phase of conception cycles had a higher risk of miscarriage (odds ratio, 5.05; 95% confidence interval: 1.04–25.51) when compared to women exposed to Q1–3 periods. Conclusion Our results show an association between brief exposure to high levels of ambient PM during the preconceptional period and early pregnancy loss, although no effect of this exposure on clinical, laboratory, and treatment outcomes was observed.

    The category of 'acute and transient psychotic disorders' (ATPDs) appeared in the ICD-10 Classification of Mental and Behavioural Disorders (ICD-10), but its distinctive features remain uncertain. To examine the course and outcome of ATPDs, pointing out differences from other types of psychosis. A one-year follow-up investigation of patients enrolled at the former World Health Organization (WHO) Centre for Research and Training in Mental Health in Aarhus (Denmark) for the WHO collaborative study on acute psychoses. Of 91 patients aged 15-60 years presenting with acute psychosis, 47 (51.6%) were diagnosed with ATPD, and it occurred more commonly in females; yet, the other acute psychoses featured mainly mood disorders and affected equally both genders. After 1 year, the ATPD diagnosis did not change in 28 cases (59.6%); the remaining developed either affective psychoses (27.7%), or schizophrenia and schizoaffective disorder (12.8%). Nearly, all patients with unchanged diagnosis of ATPD enjoyed full recovery, while those with other types of acute psychosis had significantly higher rates of recurrence or incomplete remission. Duration of illness within 4 weeks and stressful events in the 3 months before symptom onset predicted 1-year favourable clinical outcome for acute psychoses. Although ATPDs fared better over the short-term than other acute psychoses, their diagnostic stability is relatively low. © The Author(s) 2015.

    The outcome of radioiodine therapy (RIT) in Graves' hyperthyroidism (GH) mainly depends on radioiodine ( 131 I) uptake and the effective half-life of 131 I in the gland. Studies have shown that lithium carbonate (LiCO 3 ) enhances the 131 I half-life and increases the applied thyroid radiation dose without affecting the thyroid 131 I uptake. We investigated the effect of short-term treatment with LiCO 3 on the outcome of RIT in patients with long-lasting GH, its influence on the thyroid hormones levels 7 days after RIT, and possible side effects. Study prospectively included 30 patients treated with LiCO 3 and 131 I (RI-Li group) and 30 patients only with 131 I (RI group). Treatment with LiCO 3 (900 mg/day) started 1 day before RIT and continued 6 days after. Anti-thyroid drugs withdrawal was 7 days before RIT. Patients were followed up for 12 months. We defined a success of RIT as euthyroidism or hypothyroidism, and a failure as persistent hyperthyroidism. In RI-Li group, a serum level of Li was 0.571 ± 0.156 mmol/l before RIT. Serum levels of TT 4 and FT 4 increased while TSH decreased only in RI group 7 days after RIT. No toxic effects were noticed during LiCO 3 treatment. After 12 months, a success of RIT was 73.3% in RI and 90.0% in RI-Li group (P treatment with LiCO 3 as an adjunct to 131 I improves efficacy of RIT in patients with long-lasting GH. A success of RIT achieves faster in lithium-treated than in RI group. Treatment with LiCO 3 for 7 days prevents transient worsening of hyperthyroidism after RIT. Short-term use of LiCO 3 shows no toxic side effects.

    The aim of this study was to evaluate the efficiency of a short-term Intermittent Work Exercise Program (IWEP) among healthy elderly subjects. This longitudinal prospective study took place at the Strasbourg University Hospital geriatric department. One hundred and fifty older volunteers, previously determined as being free from cardiac and pulmonary disease, were separated into two age groups: the "young senior" (60.2 ± 3.1 yr) and the "older senior" groups (70.8 ± 5.2 yr). These groups were then subdivided by gender into the "young female senior", "young male senior" "older female senior" and "older male senior" groups. Before and after the IWEP, all subjects were asked to perform an incremental cycle exercise to obtain their first ventilatory threshold (VT1), maximal tolerated power (MTP), peak oxygen uptake (VO2peak) and maximal minute ventilation (MMV). The IWEP consisted of a 30-min cycling exercise which took place twice a week, and was divided into six 5-min stages consisting of 4 min at VT1 intensity and 1 min at 90% MTP. An assessment was made of the effects of the IWEP on maximal cardio-respiratory function (MTP, VO2peak, MMV) and endurance parameters (VT1, heart rate [HR] measured at pretraining VT1 and lactate concentrations at pre-training MTP). This short-term training program resulted in a significant increase of MTP (from 13.2% to 20.6%), VO2peak (from 8.9% to 16.6%) and MMV (from 11.1% to 21.8%) in all groups (pseniors" were not significantly different (p>0.05) from the "young seniors" pre-training values for the same parameters. The most striking finding in this study is that after only 9 weeks, our short-term "individually-tailored" IWEP significantly improved both maximal cardio-respiratory function and endurance parameters in healthy, previously untrained seniors.

    Full Text Available ABSTRACT Objective To evaluate the safety and short term outcomes of a new, truly minimally-invasive, mesh-less and dissection-less anchoring system for pelvic floor apical repair. Methods A prospective study was conducted using the NeuGuide™ device system for pelvic floor apical repair. The primary effectiveness outcome was centro-apical pelvic floor prolapse by POP-Q after six months. The primary safety outcome was intra-operative, immediate (first 48 h post-operative complications and adverse effects after six months. A standardized questionnaire (UDI-6 to assess quality of life at entry and during follow-up visits was used. Patients’ six months-follow-up and evaluation are reported. Results The mean age of the study population (n=10 was 63.8±12.0 years. All patients had a previous prolapse surgery. Five had a previous hysterectomy and two had stress urinary incontinence symptoms. During surgery six patients had a concurrent colporrhaphy. There was no injury to the bladder, rectum, pudendal nerves, or major pelvic vessels and no febrile morbidity was recorded. At six months, no cases of centro-apical recurrence were noted. Patients were satisfied with the procedure and had favorable quality of life scores. Using the UDI-6 questionnaire an improvement, in all domains was seen. Moreover, although the sample size was small, the improvement in urge and overflow incontinence related domains were demonstrated to be statistically significant. Conclusions This new NeuGuide™ device allows rapid and safe introduction of a suspending suture through the sacrospinous ligament and makes sacrospinous ligament fixation easy to perform, while avoiding dissection and mesh complications.

    Da Vinci Surgical System is one of the greatest inventions of the 20th century, which represents the development direction of the precise minimally invasive surgical techniques, the aim of this study was to comparing the short-term outcomes between da Vinci robot-assisted lobectomy and video-assisted thoracic surgery (VATS) lobectomy for non-small cell lung cancer. 45 pairs of non-small cell lung cancer patients underwent pulmonary lobectomy with da Vinci Robotic assisted thoracoscopic (RATS) and VATS approach during the same period from January 2014 to January 2017. The operative time, estimated blood loss (EBL), total number and total groups of dissected lymph nodes, postoperative duration of drainage, the first day volume of drainage, total volume of drainage were compared. No perioperative death and convertion to thoracotomy occured in both groups. There were significant difference between RATS group and VATS group in EBL [(50.30±32.33) mL vs (208.60±132.63) mL], the first day volume of drainage [(275.00±145.42) mL vs (347.60±125.80) mL], the dissected total number [(22.67±9.67) vs (15.51±5.41)] and total team [(6.31±1.43) vs (4.91±1.04)] of lymph node. There were no significant difference in other outcomes. RATS is safe and effective and took better short-outcomes than VATS in non-small cell lung cancer.

    N-methyl-D-aspartate receptors (NMDARs) are glutamate receptors implicated in synaptic plasticity and memory function. The specific functions of NMDA receptor subunits NR2A and NR2B have not yet been fully determined in the different types of memory. Nine Wistar rats (8-weeks-old) were subjected to the Morris water maze task to evaluate the memory behaviorally. Quantitative analysis of NR1, NR2A, and NR2B levels in the right and left forebrain of rats was performed and subunit associations with different types of memory were investigated using the Morris water maze task. Right forebrain NR2A expression was significantly increased and correlated with faster escape time onto a hidden platform, indicating involvement of short-term memory, because of the training time interval. Right forebrain NR2B expression was positively associated with long-term memory lasting 24-h (h). In the left forebrain, NR2B expression was positively related to 72-h long-term memory. In conclusion, the functions of NR2A and NR2B receptors were differentially specialized in short-term and long-term memory, depending on the right or left forebrain.

    Narrowband - ultraviolet B (NB-UVB) is an emerging, effective, and safe therapy for vitiligo, but the treatment course often requires a long duration of time which may carry a potential risk for various side effects and patients' noncompliance. To explore the effect of platelet-rich plasma (PRP) injection on the outcome of short-term NB-UVB therapy for the patients with stable vitiligo. The study included 60 stable vitiligo patients with overall symmetrical lesions. For each patient, the left side of the body was treated with NB-UVB alone (control side) while the right side was treated with NB-UVB therapy in addition to intradermal injection of PRP, every 2 weeks for 4 months. There was statistically highly significant improvement in the repigmentation in the combination group(PRP plus NB-UVB) compared with NB-UVB group. Intradermal PRP injection in combination with NB-UVB could be considered as a simple, safe, tolerable, and cheap technique for treatment of vitiligo. It shortens the duration of NB-UVB therapy and is expected to increase patient compliance. Longer follow-up is needed. © 2015 Wiley Periodicals, Inc.

    Distal Chevron osteotomy is a well-established surgical procedure for mild to moderate hallux valgus deformity. Many methods have been described for fixation of osteotomy site; secure fixation, enabling large displacement of the metatarsal head, is one of the essentials of this procedure. The purpose of the present study was to evaluate the short-term radiographic outcome of a distal Chevron osteotomy using an intramedullary plate for the correction of hallux valgus deformity. The present study evaluated 37 patients (40 feet) who underwent distal Chevron osteotomy using an intramedullary plate by periodic radiographs obtained preoperatively and at 4 weeks, 8 weeks, 3 months, and 6 months postoperatively. Correction of the hallux valgus angle averaged 17.8°, intermetatarsal angle 7.4°, distal metatarsal articular angle 2.7°, and sesamoid position 1.4 stages at 3 months postoperatively. The average lateral shift of the capital fragment was 6.5 mm. All patients achieved bone union, and there were no cases of dislocation, displacement, or avascular necrosis of the metatarsal head fragment. In conclusion, a distal Chevron osteotomy using an intramedullary plate was a favorable method for the correction of mild to moderate hallux valgus deformity. Level IV: Case series.

    Full Text Available Background: Congenital scoliosis is a developmental disorder defined as a lateral curvature of the spine. Its progressive trend and complications, such as cosmetic problems, pain and pulmonary symptoms, have put scoliosis as an important skeletal deformity that should be corrected. One of the currently accepted methods of treatment is posterior spinal fusion (PSF that may be performed with or without instrumentation. However, the use of implants in conjunction with PSF in congenital spine deformity has been debated over the past three decades primarily because of increased risk of neurological deficit and implant displacement. The aim of this study was to compare short-term and long-term outcomes of spinal fusion with and without posterior instrumentation in congenital scoliosis.Methods: In this historical cohort study, 41 patients with congenital scoliosis were recruited. All patients underwent PSF surgery between 1977 and 1996. They were divided into two groups according to the use of instrumentation: 22 congenital scoliotic patients who were treated by PSF without any instrumentation (group A, and 19 instrumented PSF patients (group B. Instrumentation was mostly performed using the Harrington rod. The major curve angle was measured before surgery, two weeks and one year after PSF surgery and at the end of the follow-up period. Results: The mean baseline curve angles were 66.3° and 69.1° in groups A and B, respectively. The mean Cobb angles one year after PSF were 43.1° and 38.4° in groups A and B, respectively. The mean follow-up period was 8 years (SD=3 and, at the end of this period, the final Cobb angles were 47.3° and 39.4° in groups A and B, respectively. Therefore, the final angle correction was 28.7% in patients without instrumentation and 43% in patients with instrumentation. The mean loss of correction was 5.5% and 4.3% in groups A and B, respectively. The final curve angles was significantly more corrected for those patients

    Coronary artery bypass grafting (CABG) is accompanied by severe impairment of cardiac autonomous regulation (CAR). This study aimed to determine whether a short-term physiotherapy exercise protocol post-CABG, during inpatient cardiac rehabilitation (CR), might improve CAR. Seventy-four patients eligible for CABG were recruited and randomised into physiotherapy exercise group (EG) or physiotherapy usual care group (UCG). EG patients underwent a short-term supervised inpatient physiotherapy exercise protocol consisting of an early mobilisation with progressive exercises plus usual care (respiratory exercises). UCG only received respiratory exercises. Forty-seven patients (24 EG and 23 UGC) completed the study. Outcome measures of CAR included linear and non-linear measures of heart rate variability (HRV) assessed before discharge. By hospital discharge, EG presented significantly higher parasympathetic HRV values [rMSSD, high frequency (HF), SD1)], global power (STD RR, SD2), non-linear HRV indexes [detrended fluctuation analysis (DFA)alpha1, DFAalpha2, approximate entropy (ApEn)] and mean RR compared to UCG (pexercise protocol during inpatient CR improves CAR at the time of discharge. Thus, exercise-based inpatient CR might be an effective non-pharmacological tool to improve autonomic cardiac tone in patient's post-CABG.

    Primary outcomes analysis of the Multicenter Study of MagLev Technology in Patients Undergoing MCS Therapy With HeartMate 3 (MOMENTUM 3) trial short-term cohort demonstrated a higher survival rate free of debilitating stroke and reoperation to replace/remove the device (primary end-point) in patients receiving the HeartMate 3 (HM3) compared with the HeartMate (HMII). In this study we sought to evaluate the individual and interactive effects of pre-specified patient subgroups (age, sex, race, therapeutic intent [bridge to transplant/bridge to candidacy/destination therapy] and severity of illness) on primary end-point outcomes in MOMENTUM 3 patients implanted with HM3 and HMII devices. Cox proportional hazard models were used to analyze patients enrolled in the "as-treated cohort" (n = 289) of the MOMENTUM 3 trial to: (1) determine interaction of various subgroups on primary end-point outcomes; and (2) identify independent variables associated with primary end-point success. Baseline characteristics were well balanced among HM3 (n = 151) and HMII (n = 138) cohorts. No significant interaction between the sub-groups on primary end-point outcomes was observed. Cox multivariable modeling identified age (≤65 years vs >65 years, hazard ratio 0.42 [95% confidence interval 0.22 to 0.78], p = 0.006]) and pump type (HM3 vs HMII, hazard ratio 0.53 [95% confidence interval 0.30 to 0.96], p = 0.034) to be independent predictors of primary outcomes success. After adjusting for age, no significant impact of sex, race, therapeutic intent and INTERMACS profiles on primary outcomes were observed. This analysis of MOMENTUM 3 suggests that younger age (≤65 years) at implant and pump choice are associated with a greater likelihood of primary end-point success. These findings further suggest that characterization of therapeutic intent into discrete bridge-to-transplant and destination therapy categories offers no clear clinical advantage, and should ideally be abandoned.

    The effects of active video game play on healthy individuals remain uncertain. A person's functional health status constitutes a dynamic interaction between components identified in the International Classification of Functioning, Disability, and Health (ICF). The aim of this study was to investigate the short-term effects of active video game play on community adults using the ICF. Sixty community adults with an average age of 59.3 years and without physical disabilities were recruited. Over 2 weeks, each adult participated in six sessions of active video game play lasting 20 minutes each. Participants were assessed before and after the intervention. Variables were collected using sources related to the ICF components, including the Hospital Anxiety and Depression Scale, Multidimensional Fatigue Inventory, Biodex Stability System, chair- rising time, Frenchay Activity Index, Rivermead Mobility Index, Chronic Pain Grade Questionnaire, Work Ability Index, and World Health Organization Quality of Life-Brief Version. Compared to baseline data, significantly reduced risk of a fall measured by Biodex Stability System and improvements in disability scores measured by the Chronic Pain Grade Questionnaire were noted. There was no significant change in the other variables measured. Short-term, active video game play reduces fall risks and ameliorates disabilities in community adults.

    Full Text Available Objective: To study the effect of short-term intensive atorvastatin treatment on interventional treatment effect and cardiac function of patients with acute coronary syndrome. Methods: A total of 104 cases of patients with acute coronary syndrome who received PCI treatment in Emergency Department of our hospital from May 2014 to November 2015 were retrospectively analyzed and divided into intensive group and routine group according to different atorvastatin treatment methods, and then biochemical indexes, cardiac ultrasound indicators and inflammatory indexes of two groups were compared. Results: Serum TG, TC, LDL-C, hs- CRP, LDH, α-HBDH, CK and CK-MB content of intensive group were significantly lower than those of routine group while HDL-C content was higher than that of routine group; E/ A ratio and LVEF of intensive group were higher than those of routine group while Tei index, systolic index and diastolic index were lower than those of routine group; TLR4 and NF-kB expression levels in peripheral blood as well as TNF-α and IL-6 content in serum of intensive group were significantly lower than those of routine group. Conclusion: Short-term intensive atorvastatin treatment improves the interventional treatment effect of patients with acute coronary syndrome, and can reduce myocardial injury, improve cardiac diastolic and systolic function and inhibit the inflammation mediated by TLR4/NF-kB.

    Individuals who report sensitivity to electromagnetic fields often report cognitive impairments that they believe are due to exposure to mobile phone technology. Previous research in this area has revealed mixed results, however, with the majority of research only testing control individuals. Two studies using control and self-reported sensitive participants found inconsistent effects of mobile phone base stations on cognitive functioning. The aim of the present study was to clarify whether short-term (50 min) exposure at 10 mW/m(2) to typical Global System for Mobile Communication (GSM) and Universal Mobile Telecommunications System (UMTS) base station signals affects attention, memory, and physiological endpoints in sensitive and control participants. Data from 44 sensitive and 44 matched-control participants who performed the digit symbol substitution task (DSST), digit span task (DS), and a mental arithmetic task (MA), while being exposed to GSM, UMTS, and sham signals under double-blind conditions were analyzed. Overall, cognitive functioning was not affected by short-term exposure to either GSM or UMTS signals in the current study. Nor did exposure affect the physiological measurements of blood volume pulse (BVP), heart rate (HR), and skin conductance (SC) that were taken while participants performed the cognitive tasks.

    Prior studies have suggested that the association between the alliance and depression improvement varies as a function of prior history of depression. We sought to replicate these findings and extend them to short-term psychodynamic supportive psychotherapy (SPSP) in a sample of patients who were randomized to one of these treatments and were administered the Helping Alliance Questionnaire (N=282) at Week 5 of treatment. Overall, the alliance was a predictor of symptom change (d=0.33). In SPSP, the alliance was a modest but robust predictor of change, irrespective of prior episodes (d=0.25-0.33). By contrast, in CBT, the effects of the alliance on symptom change were large for patients with 0 prior episodes (d=0.86), moderate for those with 1 prior episode (d=0.49), and small for those with 2+ prior episodes (d=0.12). These findings suggest a complex interaction between patient features and common vs. specific therapy processes. In CBT, the alliance relates to change for patients with less recurrent depression whereas other CBT-specific processes may account for change for patients with more recurrent depression.

    Abstract Right ventricular (RV) and left ventricular (LV) dysfunction is an important determinant of poor clinical status in repaired patients with tetralogy of Fallot (TOF). The purpose of our study is to assess the impact of surgical repair on short-term RV and LV function by 2-dimensional speckle tracking echocardiography (STE). Sixty-seven patients (median age 12 months) with TOF before and 6 months after repair and 35 healthy subjects were studied. The patients were divided into the younger (age at surgery ≤12 months) and older (age at surgery >12 months) subgroups. RV and LV global longitudinal systolic strain and strain rate (SR), and LV global circumferential and radial systolic strain and SR were measured by STE. After repair, RV longitudinal strain and SR increased in the younger patients, whereas RV longitudinal SR was decreased in the older patients. LV deformation parameters were unchanged in all patients. In the multivariate analysis, patients with better RV and LV deformation parameters preoperatively were identified to have better RV and LV strain and SR postoperatively (P < 0.05 for all). The surgical approach of the pulmonary valve ring was predictive of RV and LV systolic function postoperatively (P < 0.05 for all). After TOF repair, short-term RV function improvement is identified in the younger but not in the older patients, whereas LV function is unchanged in all patients. The preoperative RV and LV deformational indices are the determinant of postoperative biventricular function improvement. STE appears to be a valuable tool for assessment of biventricular function after congenital heart disease surgery. PMID:27495064

    Both the Centers for Medicare and Medicaid Services' (CMS) Hospital Compare star rating and surgical case volume have been publicized as metrics that can help patients to identify high-quality hospitals for complex care such as cancer surgery. The current study evaluates the relationship between the CMS' star rating, surgical volume, and short-term outcomes after major cancer surgery. National Medicare data were used to evaluate the relationship between hospital star ratings and cancer surgery volume quintiles. Then, multilevel logistic regression models were fit to examine the association between cancer surgery outcomes and both star rankings and surgical volumes. Lastly, a graphical approach was used to compare how well star ratings and surgical volume predicted cancer surgery outcomes. This study identified 365,752 patients undergoing major cancer surgery for 1 of 9 cancer types at 2,550 hospitals. Star rating was not associated with surgical volume (P cancer surgery outcomes (mortality, complication rate, readmissions, and prolonged length of stay). The adjusted predicted probabilities for 5- and 1-star hospitals were 2.3% and 4.5% for mortality, 39% and 48% for complications, 10% and 15% for readmissions, and 8% and 16% for a prolonged length of stay, respectively. The adjusted predicted probabilities for hospitals with the highest and lowest quintile cancer surgery volumes were 2.7% and 5.8% for mortality, 41% and 55% for complications, 12.2% and 11.6% for readmissions, and 9.4% and 13% for a prolonged length of stay, respectively. Furthermore, surgical volume and the star rating were similarly associated with mortality and complications, whereas the star rating was more highly associated with readmissions and prolonged length of stay. In the absence of other information, these findings suggest that the star rating may be useful to patients when they are selecting a hospital for major cancer surgery. However, more research is needed before these ratings can

    Full Text Available OBJECTIVES: To evaluate the impact of surgical treatment of stress urinary incontinence on the sexual function of women and to identify whether such treatment can improve their sexual function and overall quality of life. MATERIALS AND METHODS: 64 heterosexual women with such indication were studied using the Female Sexual Function Index (FSFI questionnaire, modified by introducing one question to evaluate the impact of urine loss. This was applied preoperatively and six months after surgery. RESULT: Among these 64 patients, 60.94% had regular sexual activity, while 39.06% did not. Among sexually active patients, 59% had urine loss during sexual intercourse and, of these, 87% had urine losses in half or more of sexual relations. There were no statistically significant differences in assessments of desire, arousal, lubrication, orgasm, satisfaction and pain, or in totaling the scores, between the preoperative period and six months after surgical treatment. However, the scores for urine losses during sexual intercourse were significantly better after the operation. CONCLUSIONS: Analysis of the results allowed the following conclusions to be reached: Urine lost during sexual activity was frequent among patients with stress urinary incontinence. Suburethral support surgery did not jeopardize sexual activity. Patients cured of stress urinary incontinence did not present improvement in sexual function.

    Native parasitic plants may be used to infect and control invasive plants. We established microcosms with invasive Mikania micrantha and native Coix lacryma-jobi growing in mixture on native soils, with M. micrantha being infected by parasitic Cuscuta campestris at four intensity levels for seven weeks to estimate the top-down effects of plant parasitism on the biomass and functional diversity of soil microbial communities. Parasitism significantly decreased root biomass and altered soil microbial communities. Soil microbial biomass decreased, but soil respiration increased at the two higher infection levels, indicating a strong stimulation of soil microbial metabolic activity (+180%). Moreover, a Biolog assay showed that the infection resulted in a significant change in the functional diversity indices of soil microbial communities. Pearson correlation analysis indicated that microbial biomass declined significantly with decreasing root biomass, particularly of the invasive M. micrantha. Also, the functional diversity indices of soil microbial communities were positively correlated with soil microbial biomass. Therefore, the negative effects on the biomass, activity and functional diversity of soil microbial community by the seven week long plant parasitism was very likely caused by decreased root biomass and root exudation of the invasive M. micrantha.

    The microvascular benefits of regional diets appear in the literature; however, little is known about Nordic-type diets. We investigated the effects of a short-term, adapted, Nordic diet on microvascular function in younger and older individuals at rest and during activity. Thirteen young (mean age: 28 y; standard deviation: 5 y) and 15 older (mean age: 68 y; standard deviation: 6 y) participants consumed a modified Nordic diet for 4 wk. Laser Doppler flowmetry and transcutaneous oxygen monitoring were used to assess cutaneous microvascular function and oxygen tension pre- and postintervention; blood pressure, body mass, body fat percentage, ratings of perceived exertion, and peak heart rate during activity were examined concurrently. Axon-mediated vasodilation improved in older participants (1.17 [0.30] to 1.30 [0.30]; P Nordic diet might improve microvascular health. Copyright © 2017 Elsevier Inc. All rights reserved.

    Cognitive skills are the emergent property of distributed neural networks. The distributed nature of these networks does not necessarily imply a lack of specialization of the individual brain structures involved. However, it remains questionable whether discrete aspects of high-level behavior might be the result of localized brain activity of individual nodes within such networks. The phonological loop of working memory, with its simplicity, seems ideally suited for testing this possibility. Central to the development of the phonological loop model has been the description of patients with focal lesions and specific deficits. As much as the detailed description of their behavior has served to refine the phonological loop model, a classical anatomoclinical correlation approach with such cases falls short in telling whether the observed behavior is based on the functions of a neural system resembling that seen in normal subjects challenged with phonological loop tasks or whether different systems have taken over. This is a crucial issue for the cross correlation of normal cognition, normal physiology, and cognitive neuropsychology. Here we describe the functional anatomical patterns of JB, a historical patient originally described by Warrington et al. (1971), a patient with a left temporo-parietal lesion and selective short phonological store deficit. JB was studied with the H 2 15 O PET activation technique during a rhyming task, which primarily depends on the rehearsal system of the phonological loop. No residual function was observed in the left temporo-parietal junction, a region previously associated with the phonological buffer of working memory. However, Broca's area, the major counterpart of the rehearsal system, was the major site of activation during the rhyming task. Specific and autonomous activation of Broca's area in the absence of afferent inputs from the other major anatomical component of the phonological loop shows that a certain degree of

    We measured lung function before and after video-assisted thoracoscopic apical bullectomy and talc poudrage in patients with spontaneous pneumothoraces. Seventy-two patients were prospectively followed up for 12 months. The indications for surgery were recurrent pneumothoraces (n = 58), bilateral pneumothoraces (n = 8), and persistent air leak (n = 6). There were 46 males and 26 females with mean age of 29 years (range 15-61 years). The results were analyzed using paired t tests. There were no recurrences. There were 4 complications (5.6%): 1 wound infection, 1 case of pneumonia, and 2 persistent air leaks each lasting 1 week. There were no conversions to open surgery. Preoperative and 6-month pulmonary function test results were available on 41 patients, and 35 patients completed 12-month pulmonary function tests. Twelve-month values (mean percent ± SD) were as follows: Forced expiratory volume in 1 second fell from 95 ± 19 to 89 ± 16 (P = .02); forced expiratory volume in 1 second/forced vital capacity ratio was unchanged, 95 ± 12 versus 94 ± 13 (P = .9); total lung capacity fell from 106 ± 19 to 98 ± 12 (P = 0.002); vital capacity fell from 100 ± 22 to 96 ± 16 (P = .05); residual volume fell from 126 ± 32 to 107 ± 29 (P = .002); and diffusion capacity for carbon monoxide corrected for alveolar volume was unchanged, 88 ± 15 versus 91 ± 17 (P = .07). Flow rates and diffusion capacities were preserved, but lung volumes were slightly reduced at 1 year. Video-assisted thoracoscopic apical bullectomy and talc poudrage is an effective treatment for spontaneous pneumothoraces with a low complication rate and recurrence rate and only minor changes in pulmonary function at 1 year.

    The aim of our study was to compare short-term outcomes of robotic and laparoscopic sphincter-saving total mesorectal excision (TME) in male patients with mid-low rectal cancer (RC) after neadjuvant chemoradiotherapy (NCRT). The study was conducted as a retrospective review of a prospectively maintained database, and we analyzed 14 robotic and 65 laparoscopic sphincter saving TME (R-TME and L-TME, respectively) performed by one surgeon between 2005 and 2013. Patient characteristics, perioperative recovery, postoperative complications and and pathology results were compared between the two groups. The patient characteristics did not differ significantly between the two groups. Median operating time was longer in the R-TME than in the L-TME group (182 min versus 140 min). Only two conversions occurred in the L-TME group. No difference was found between groups regarding perioperative recovery and postoperative complication rates. The median number of harvested lymph nodes was higher in the RTME than in the L-TME group (32 versus 23, p = 0.008). The median circumferential margin (CRM) was 10 mm in the R-TME group, 6.5 mm in the L-TME group (p = 0.047. The median distal resection margin (DRM) was 27.5 mm in the R-TME, 15 mm in the L-TME group (p = 0.014). Macroscopic grading of the specimen in the R-TME group was complete in all patients. In the L-TME group, grading was complete in 52 (80%) and incomplete in 13 (20%) cases (p = 0.109). R-TME is a safe and feasible procedure that facilitates performing of TME in male patients with mid-low RC after NCRT.

    Various types of preoperative chemoradiotherapy (CRT) have been established for rectal cancer; thus, Physicians will need to refine the selection of appropriate preoperative CRT for different patients since there are various treatment regimens. Oral tegafur-uracil (UFT) plus leucovorin (LV) is commonly used to treat rectal cancer in Japan. Oral chemotherapy offers patients many potential advantages. Since 2008, we have been performing preoperative CRT with intermittent oral UFT plus LV in locally advanced rectal cancer patients to prevent postoperative local recurrence. Here, in a retrospective analysis, we evaluated the efficacy and short-term outcomes of preoperative CRT with intermittent oral UFT plus LV. We analyzed data from 62 patients with locally advanced rectal cancer, including 31 patients who underwent preoperative CRT between 2009 and 2013 (the CRT group) and 31 patients who were treated with surgery alone between 2001 and 2008 (the non-CRT group). Clinicopathologically, both groups included patients with rectal cancer at clinical tumor stages III-IV or clinical node stages 0-III. In the CRT group, curative operations were performed ≥8 weeks after CRT. Patients were concomitantly treated with 2 cycles of oral UFT (300 mg/m 2 /day, days 1-14 and 29-42) plus LV (75 mg/day, days 1-14 and 29-42) and 45 Gy of radiotherapy. Chemotherapy was repeated every 28 days, followed by a 2-week break. The completion rate of CRT was high at 94% (n = 29/31). The downstaging rate of CRT was 61% (n = 19/31). The pathological complete response rate was 6.5% (n = 2/31). Significant differences were observed in the 3-year local recurrence rate between the two groups (P rectal cancer. A further investigation of a diversification of preoperative CRT for Japanese rectal cancer patients is required.

    This study was designed to evaluate short-term physiologic outcomes of transitioning neonates with bronchopulmonary dysplasia (BPD) from intensive care unit (ICU) ventilators to both the Trilogy 202 (Philips Healthcare, Andover, MA) and LTV 1200 (CareFusion, Yorba Linda, CA) subacute ventilators. Six infants with BPD requiring tracheostomies for support with a neonatal-specific ICU ventilator underwent placement of esophageal balloon catheters, airway pressure transducers, flow sensors, oxygen saturation (SpO 2 ), and end tidal carbon dioxide (P ET CO 2 ) monitors. Noninvasive gas exchange, airflow, and airway and esophageal pressures (P ES ) were recorded following 20 min on the ICU ventilator. The infants were placed on the Trilogy 202 and LTV 1200 ventilators in random order at identical settings as the ICU ventilator. We measured noninvasive gas exchange, pressure-rate product (respiratory rate × ΔP ES ), ventilator response times, and the percentage of spontaneous breaths that triggered the ventilator at 20 min in each subject while being supported with each of the different subacute ventilators. The mean (SD) weight of the six infants was 4.983 (0.56) kg. There were no differences in heart rate ( p = 0.51) or SpO 2 ( p = 0.97) but lower P ET CO 2 , ΔP ES , respiratory rate, pressure rate-product, response times, and greater percentage of subject initiated breaths that triggered the ventilator ( p ventilator to the Trilogy 202 ventilator. In this small group of infants with BPD, the Trilogy 202 ventilator performed better than the LTV 1200. The improved subject efforts, per cent subject triggering, and response times observed with the Trilogy are likely related to differences in triggering algorithms, location of triggering mechanisms, and gas delivery system performance within the ventilators. These pilot data may be useful for informing future clinical study design and understanding differences in the level of support provided by different subacute

    Review echocardiography and outcomes before and after Ross procedures, including patients undergoing biventricular conversion with Damus-Kaye-Stansel (DKS) takedown. A retrospective review was performed on 62 patients undergoing simple (control group) and complex Ross procedures, including 12 patients who underwent biventricular conversion with Ross operation and DKS takedown (complex). Echocardiography was reviewed preoperatively and at discharge and late follow-up. Kaplan-Meier estimates of patient survival and freedom from reintervention were obtained. In all, 62 patients had a median age of 4.5 years (interquartile range [IQR]: 1-12.5), weight of 16.4kg (IQR: 8-41), and follow-up of 3.8 years (IQR: 1.3-6). The complex DKS takedown group had 2 deaths, no neoaortic valve or root reinterventions, and 3 right ventricular outflow tract (VOT) reinterventions. There were no differences from the control group in left VOT or right VOT reinterventions. Neither group showed differences between pre- and late follow-up aortic root and ascending aorta dimensions, and no correlations were found among preoperative pulmonary valve (PV) size, late aortic regurgitation (AR), aortic root, or ascending aortic Z-scores. Aortic valve size increased from discharge to late follow-up for both groups (P ≤ .05); 90% of patients at late follow-up had mild or less AR with similar distributions in severity between complex and control groups. Severity of late AR showed no correlation with preoperative PV size and is independent of it. The Ross procedure has good short-term results in simple and complex patients and should be considered in those undergoing Ross operation with biventricular conversion and DKS takedown. Moreover, native PV size should not be a contraindication for Ross procedure. Copyright © 2016 Elsevier Inc. All rights reserved.

    Our understanding of the expertise and equipment required to air transport injured soldiers with severe traumatic brain injuries (TBIs) continue to evolve. We conducted a retrospective chart review of characteristics, interventions required and short-term outcomes of patients with severe TBI managed by the US Air Force Critical Care Air Transport Teams (CCATTs) deployed in support of Operation Iraqi Freedom and Operation Enduring Freedom between 1 June 2007 and 31 August 2010. Patients were cared for based on guidelines given by the Brain Trauma Foundation and the Joint Theater Trauma System by non-neurosurgeon physicians with dedicated neurocritical care training. We report basic characteristics, injuries, interventions required and complications during transport. Intracranial haemorrhage was the most common diagnosis in this cohort. Most injuries were weapon related. During this study, there were no reported in-flight deaths. The majority of patients were mechanically ventilated. There were 45 patients who required at least one vasopressor to maintain adequate tissue perfusion, including four patients who required three or more. Some patients required intracranial pressure (ICP) management, treatment of diabetes insipidus and/or seizure prophylaxis medications. Air transport personnel must be prepared to provide standard critical care but also care specific to TBIs, including ICP control and management of diabetes insipidus. Although these patients and their potential complications are traditionally managed by neurosurgeons, those providers without neurosurgical backgrounds can be provided this training to help fill a wartime need. This study provides data for the future development of air transport guidelines for validating and clearing flight surgeons. Published by the BMJ Publishing Group Limited.

  16. Chloroplast digestion and the development of functional kleptoplasty in juvenile Elysia timida (Risso, 1818 as compared to short-term and non-chloroplast-retaining sacoglossan slugs.

    Full Text Available Sacoglossan sea slugs are the only metazoans known to perform functional kleptoplasty, the sequestration and retention of functional chloroplasts within their digestive gland cells. Remarkably, a few species with this ability can survive starvation periods of 3-12 months likely due to their stolen chloroplasts. There are no reports of kleptoplast transfer from mother slug to either eggs or juveniles, demonstrating that each animal must independently acquire its kleptoplasts and develop the ability to maintain them within its digestive gland. We present here an investigation into the development of functional kleptoplasty in a long-term kleptoplast retaining species, Elysia timida. Laboratory-reared juvenile slugs of different post-metamorphic ages were placed in starvation and compared to 5 known short-term retaining slug species and 5 non-retaining slug species. The subsequent results indicate that functional kleptoplasty is not performed by E. timida until after 15 days post-metamorphosis and that by 25 days, these animals outlive many of the short-term retention species. Digestive activity was also monitored using lysosomal abundance as an indicator, revealing different patterns in starving juveniles versus adults. Starved juveniles were reintroduced to food to determine any differences in digestive activity when starvation ends, resulting in an increase in the number of kleptoplasts, but no overall change in lysosomal activity. By revealing some of the changes that occur during early development in these animals, which begin as non-kleptoplast-retaining and grow into long-term retaining slugs, this investigation provides a basis for future inquiries into the origin and development of this remarkable ability.

  17. A randomly-controlled study on the cardiac function at the early stage of return to the plains after short-term exposure to high altitude.

    Full Text Available High altitude acclimatization and adaptation mechanisms have been well clarified, however, high altitude de-adaptation mechanism remains unclear. In this study, we conducted a controlled study on cardiac functions in 96 healthy young male who rapidly entered the high altitude (3700 m and returned to the plains (1500 m after 50 days. Ninety eight healthy male who remained at low altitude were recruited as control group. The mean pulmonary arterial pressure (mPAP, left ventricular ejection fraction (LVEF, left ventricular fraction shortening (LVFS, cardiac function index (Tei index were tested. Levels of serum creatine kinase isoform MB (CK-MB, lactate dehydrogenase isoenzyme-1 (LDH-1, endothelin-1 (ET-1, nitrogen oxide (NO, serum hypoxia-inducible factor-1α (HIF-1α, 8-iso-prostaglandin F(2α (8-iso PGF(2α, superoxide dismutase (SOD and malonaldehyde (MDA were measured at an altitude of 3700 m and 1500 m respectively. The results showed that after short-term exposure to high altitude mPAP and Tei index increased significantly, while LVEF and LVFS decreased significantly. These changes were positively correlated with altitude. On the 15(th day after the subjects returned to low altitude, mPAP, LVEF and LVFS levels returned to the same level as those of the control subjects, but the Tei index in the returned subjects was still significantly higher than that in the control subjects (P<0.01. We also found that changes in Tei index was positively correlated with mPAP, ET-1, HIF-1α and 8-iso PGF(2α levels, and negatively correlated with the level of NO, LVEF, LVFS, CK-MB and LDH-1. These findings suggest that cardiac function de-adapts when returning to the plains after short-term exposure to high altitude and the function recovery takes a relatively long time.

    To determine whether a medication review by a specialized team would promote regimen changes in elders taking multiple medications and to measure the effect of regimen changes on monthly cost and functioning. A randomized-controlled trial. Health center ambulatory clinic. Community-dwelling older adults taking five or more medications were assessed at baseline and 6 weeks. A medication-change intervention group of 57 elders was compared with a control group of 76 elder adults. The primary intervention was a comprehensive review and recommended modification of a patient's medication regimen. Changes were endorsed by each patient's primary physician and discussed with each patient. Measures were the Timed Manual Performance Test, Physical Performance Test, Functional Reach Assessment, subtests from the Wechsler Adult Intelligence Scale, a modified Randt Memory Test, the Center for Epidemiological Studies-Depression Scale, the Self-Rating Anxiety Scale, and the Rand 36-item Health Survey 1.0. Comorbidity was determined using the International Classification of Diseases, Ninth Revision, Clinical Modification. Medication usage was determined using brown bag review. Intervention subjects decreased their medications by an average of 1.5 drugs. No differences in functioning were observed between groups. Intervention subjects saved an average $26.92 per month in wholesale medication costs; control subjects saved $6.75 per month (P<.006). Although the intervention significantly reduced the medications taken and monthly cost, most patients were resistant to reducing medications to the recommended level. Further study is needed to understand patient resistance to reducing adverse polypharmacy and to devise better strategies for addressing this important problem in geriatric health. Greater focus on prescriber behavior is recommended.

    To determine the short- and long-term improvement in airflow dynamics in patients undergoing tracheobronchial stent placement for benign airway stenoses. Twenty-two patients underwent 34 tracheal and/or bronchial stent placement procedures for benign airway stenoses and had the results of pulmonary function tests available. Stent placement indications included bronchomalacia after lung transplantation (n = 11), postintubation stenoses (n = 6), relapsing polychondritis (n = 2), and 1 each of tracheomalacia, tracheal compression, and histoplasmosis. Six patients underwent more than one stent placement procedure (range: 2-7 procedures). The mean forced expiratory volume in one second (FEV(1) ), forced expiratory flow rate in the midportion of the forced vital capacity curve (FEF(25-75) ), forced vital capacity, and peak flow (PF) rate obtained before stent placement were compared with those immediately after stent placement and with those measurements most remote from stent placement using the paired two-tailed test. All patients reported improved respiratory function immediately after stent placement. The mean FEV(1), FEF(25-75), and PF rate improved significantly (p stent placement. On long-term follow-up averaging 15 months after stent placement, these parameters declined despite patients' subjective sense of improvement. Segregating the population into transplant and nontransplant airway stenosis etiologies, however, FEF(25-75) and PF rate remained significantly improved (p = 0.045, p = 0.027, respectively), over the long term for the latter. FEV increased after subsequent stent placements for patients receiving multiple stents. Stent placement for benign tracheobronchial stenoses provides significant immediate improvement in airflow dynamics. Long-term improvement in airflow obstruction may be expected, and additional stent placements may further improve pulmonary function.

    Modafinil is a drug developed and used for the treatment of excessive lethargy. Even though very effective for sleep disorders, it is still controversial whether modafinil can improve performance in high-order cognitive processes such as memory and executive function. This randomized, double-blind, placebo-controlled, crossover trial was designed to evaluate the effect of modafinil (compared to placebo) on the cognitive functions of healthy students. 160 volunteers were recruited and allocated randomly to modafinil or placebo group, and were assessed using the Stroop Test, BCET test and Digit span test. We found a significant difference in favor of modafinil compared to placebo in the proportion of correct answers of Stroop Test in congruent situation. A significant shorter latency of modafinil group in the incongruent situation of Stroop test was also found. No differences were found in Digit Span, or BCET tests. The study demonstrated that modafinil does not enhance the global cognitive performance of healthy non-sleep deprived students, except regarding non-demanding tasks. In particular, this drug does not seem to have positive effects on mental processes that sustain studying tasks in the college population under normal conditions. We expect these findings to demystify the use of this drug and help decision making concerning pharmacological public policies.

    The objective of this study was to determine effect of ruminal acidosis (RA) and low feed intake [LFI] on the regional barrier function of the gastrointestinal tract. Twenty-one Holstein steers were fed for ad libitum intake for 5 d (control [CON]), fed at 25% of ad libitum intake for 5 d (LFI), or provided 2 d of ad libitum intake followed by 1-d of feed restriction (25% of ad libitum intake), 1 d where 30% of ad libitum dry matter intake (DMI) was provided as pelleted barley followed by the full allocation (RA) and fed for ad libitum intake the following day. Tissues and digesta from the rumen, omasum, duodenum, jejunum, ileum, cecum, proximal, and distal colon were collected. Permeability was assessed using the mucosal-to-serosal flux of inulin (JMS-inulin) and mannitol (JMS-mannitol). Digesta pH was 0.81, 0.63, and 0.42 pH units less for RA than CON in the rumen, cecum, and proximal colon; while, LFI had pH that was 0.47 and 0.36 pH units greater in the rumen and proximal colon compared to CON. Total ruminal short-chain fatty acid (SCFA) concentration were less for LFI (92 mM; P = 0.010) and RA (87 mM; P = 0.007) than CON (172 mM) steers. In the proximal colon, the proportion of butyrate (P = 0.025 and P = 0.022) and isobutyrate (P = 0.019 and P = 0.019) were greater, and acetate (P = 0.028 and P = 0.028) was less for LFI and RA, respectively, when compared to CON steers. Ruminal papillae length, width, perimeter, and surface area were 1.21 mm, 0.78 mm, 3.84 mm, and 11.15 mm2 less for LFI than CON; while, RA decreased papillae width by 0.52 mm relative to CON. The JMS-mannitol was less for LFI steers than CON in the proximal colon (P = 0.041) and in the distal colon (P = 0.015). Increased gene expression for claudin 1, occludin, tight-cell junction protein 1 and 2, and toll-like receptor 4 were detected for LFI relative to CON in the rumen, jejunum, and proximal colon. For RA steers, expression of toll-like receptor 4 in the rumen, and occludin and tight

    Fire is a major ecosystem driver, causing significant changes in soil nutrients and microbial community structure and functionality. Post-fire soil dynamics can vary depending on rainfall patterns, although variations in response to drought are poorly known. This is particularly important in areas with poor soils and limited rainfall, like arid and semiarid ones. Furthermore, climate change projections in many such areas anticipate reduced precipitation and longer drought, together with an increase in fire severity. The effects of experimental drought and fire were studied on soils in a Mediterranean Cistus-Erica shrubland in Central Spain. A replicated (n = 4) field experiment was carried out in which four levels of rainfall pattern were implemented by means of a rain-out shelters and irrigation system. The treatments were: environmental control (natural rainfall), historical control (long-term average rainfall, 2 months drought), moderate drought (25% reduction of historical control, 5 months drought) and severe drought (45% reduction, 7 months drought). After one growing season, the plots were burned with high fire intensity, except a set of unburned plots that served as control. Soils were collected seasonally during one year and variables related to soil nutrient availability and microbial community structure and functionality were studied. Burned soils increased nutrient availability (P, N, K) with respect to unburned ones, but drought reduced such an increase in P, while it further increased N and K. Such changes in available soil nutrients were short-lived. Drought caused a further decrease of enzyme activities, carbon mineralization rate and microbial biomass. Fire decreased the relative abundance of fungi and actinomycetes. However, fire and drought caused a further reduction in fungi, with bacteria becoming relatively more abundant. Arguably, increasing drought and fires due to climate change will likely shift soil recovery after fire.

    The functional structures of communities respond to environmental changes by both species replacement (turnover) and within-species variation (intraspecific trait variability; ITV). Evidence is lacking on the relative importance of these two components, particularly in response to both short- and long-term environmental disturbance. We hypothesized that such short- and long-term perturbations would induce changes in community functional structure primarily via ITV and turnover, respectively. To test this we applied an experimental design across long-term mown and abandoned meadows, with each plot containing a further level of short-term management treatments: mowing, grazing and abandonment. Within each plot, species composition and trait values [height, shoot biomass, and specific leaf area (SLA)] were recorded on up to five individuals per species. Positive covariations between the contribution of species turnover and ITV occurred for height and shoot biomass in response to both short- and long-term management, indicating that species turnover and intraspecific adjustments selected for similar trait values. Positive covariations also occurred for SLA, but only in response to long-term management. The contributions of turnover and ITV changed depending on both the trait and management trajectory. As expected, communities responded to short-term disturbances mostly through changes in intraspecific trait variability, particularly for height and biomass. Interestingly, for SLA they responded to long-term disturbances by both species turnover and intraspecific adjustments. These findings highlight the importance of both ITV and species turnover in adjusting grassland functional trait response to environmental perturbation, and show that the response is trait specific and affected by disturbance regime history.

    Deep earthwork activities carried out before vineyard plantation can severely upset soil profile properties. As a result, soil features in the root environment are often much more similar to those of the underlying substratum than those of the original profile. The time needed to recover the original soil functions is ecologically relevant and may strongly affect vine phenology and grape yield, particularly under organic viticulture. The general aim of this work was to investigate soil resilience after vineyard pre-planting earthworks. In particular, an old and a new vineyard, established on the same soil type, were compared over a five year period for soil chemical, physical, micro and mesobiological properties. The investigated vineyards (Vitis vinifera L., cv. Sangiovese) were located in the Chianti Classico district (Central Italy), on stony and calcareous soils and were not irrigated. The older vineyard was planted in 2000, after slope reshaping by bulldozing and back hoe ploughing down to about 0.8-1.0 m. The new vineyard was planted in 2011, after equivalent earthwork practices carried out in the summer of 2009. Both vineyards were organically managed and fertilized only with compost every autumn (1000 kg ha-1 per year). The new vineyard was cultivated by periodic tillage, while the old vineyard was managed with alternating grass-covered and tilled inter-rows. Soil samples were collected at 0-15 cm depth from the same plots of the new and old vineyards, during the springtime from 2010 to 2014. The old vineyard was sampled in both the tilled and the grass-covered swaths. According to the results from physical and chemical analyses, the new vineyard, during the whole 2010-2014 period, showed lower TOC, N, C/N and EC values, along with higher silt and total CaCO3 contents than the old vineyard, suggesting still evolving equilibrium conditions. The microarthropod analysis showed significantly different abundances and communities' structures, in relation to both

    Studies with preschool children have shown significant links between children's executive function (EF) and theory of mind (ToM), but few studies have examined these associations in primary school children. To address this gap, we designed a three-wave cross-lagged longitudinal study in which we followed a group of 113 children (61 boys) across three time points from age 9.5-10.5years (mean age at Time 1=112.3months, SD=4.18; mean age at Time 2=118.3months, SD=4.15; mean age at Time 3=124.7months, SD=4.06). At each time point, we measured EF (working memory and inhibitory control), ToM, and language. Our analyses showed (a) moderate rank-order stability of individual differences in both EF and ToM and (b) growth in ToM task performance across time. Cross-lagged longitudinal analyses revealed an asymmetric developmental relation between ToM and working memory. Early working memory predicted later ToM but not vice versa. Our results suggest a specific role for working memory in the ongoing development of ToM in middle childhood. Copyright © 2017 Elsevier Inc. All rights reserved.

    Inclusion of processed amla have been found to enhance the functional properties and nutritional value of ice cream by augmenting the fiber content, total phenols, tannins, ascorbic acid and antioxidant activity. The present investigation assessed the changes in these constituents, color values (L, a* and b*), melting rate, sensory scores and microbiological quality of ice cream containing amla shreds, pulp, preserve, candy and powder during 60 days' storage at - 18 to - 20 °C. The total solids increased slightly whereas the antioxidant activity, total phenols, ascorbic acid and tannins decreased on storage. The L values declined whereas a* and b* values amplified, the rate of change being highest in candy containing sample followed by preserve. The first drip time of all the samples increased whereas melting rate decreased. The overall acceptability scores declined non significantly. Standard plate count of all the ice cream samples decreased significantly whereas yeast and molds were not detected throughout the storage. The psychrophiles were not spotted up to 30 days, thereafter, a small increase was observed.

    To evaluate the effects of indoor and outdoor PM2.5 (fine particulate matter, particulate matter with an aerodynamic diameter ≤ 2.5 µm) on lung function of college students in autumn and winter in Wuhan. In this panel study, 37 college students (excluded subject of respiratory disease and smoking history) aged 19 - 21 were investigated by cluster sampling in a university in Wuhan. The follow-up study lasted for 28 days in total, including two study periods, Oct. 29 to Nov. 11, 2009 (autumn) and Dec. 23, 2009 to Jan.5, 2010 (winter), the peak expiratory flow (PEF) of the college students were measured daily in the morning and evening in the university. PM10 and PM2.5 were monitored indoors and outdoors. The effects of PM on lung function of college students were analyzed by using generalized estimating equation (GEE). Average daily concentrations of indoor, outdoor PM2.5 in autumn were (91.3 ± 43.7) and (104.2 ± 49.4) µg/m(3) respectively, while in winter the concentrations of indoor and outdoor PM2.5 were (110.6 ± 42.3) and (143.5 ± 51.2) µg/m(3). The single pollutant model showed that in winter, the evening PEF decrement was significantly associated with increasing outdoor PM2.5. With an increase of 10 µg/m(3) outdoor PM2.5, the PEF measured in the evening decreased 1.27 L/min (95%CI: 0.02 - 2.52 L/min, respectively). Meanwhile, the results showed that 2-days lagged outdoor PM2.5 was also significantly associated with morning PEF. An increase of 10 µg/m(3) 2-days lagged outdoor PM2.5 caused the decrease of 1.82 L/min (95%CI: -3.53 - -0.11 L/min) of PEF measured in the morning. Controlling the influence of gaseous pollutants and building the two pollutants models, the results indicated that no significant changes of PEF of students being exposed to PM2.5 on same day (lag 0) were observed. However, under consideration of SO2 effect, significant association between an increase of 10 µg/m(3) 2-days lagged outdoor PM2.5 and changes of morning PEF (-1.81 L

    We applied rhythmic binaural sound to Parkinson's Disease (PD) patients to investigate its influence on several symptoms of this disease and on Electrophysiology (Electrocardiography and Electroencephalography (EEG)). We conducted a double-blind, randomized controlled study in which rhythmic binaural beats and control were administered over two randomized and counterbalanced sessions (within-subjects repeated-measures design). Patients ([Formula: see text], age [Formula: see text], stage I-III Hoehn & Yahr scale) participated in two sessions of sound stimulation for 10[Formula: see text]min separated by a minimum of 7 days. Data were collected immediately before and after both stimulations with the following results: (1) a decrease in theta activity, (2) a general decrease in Functional Connectivity (FC), and (3) an improvement in working memory performance. However, no significant changes were identified in the gait performance, heart rate or anxiety level of the patients. With regard to the control stimulation, we did not identify significant changes in the variables analyzed. The use of binaural-rhythm stimulation for PD, as designed in this study, seems to be an effective, portable, inexpensive and noninvasive method to modulate brain activity. This influence on brain activity did not induce changes in anxiety or gait parameters; however, it resulted in a normalization of EEG power (altered in PD), normalization of brain FC (also altered in PD) and working memory improvement (a normalizing effect). In summary, we consider that sound, particularly binaural-rhythmic sound, may be a co-assistant tool in the treatment of PD, however more research is needed to consider the use of this type of stimulation as an effective therapy.

    We recently showed that a short-term high-fat diet blunted exercise performance in rats, accompanied by increased uncoupling protein levels and greater respiratory uncoupling. In this study, we investigated the effects of a similar diet on physical and cognitive performance in humans. Twenty sedentary men were assessed when consuming a standardized, nutritionally balanced diet (control) and after 7 d of consuming a diet comprising 74% kcal from fat. Efficiency was measured during a standardized exercise task, and cognition was assessed using a computerized assessment battery. Skeletal muscle mitochondrial function was measured using (31)P magnetic resonance spectroscopy. The diet increased mean ± se plasma free fatty acids by 44% (0.32±0.03 vs. 0.46±0.05 mM; Pdiet consumption also increased subjects' simple reaction times (Pdiet blunts whole-body efficiency and cognition in sedentary men. We suggest that this effect may be due to increased respiratory uncoupling.

    The hypothesis tested in this study, carried out on elderly Italian women with recent hip fracture, was to assess the extent to which the effect of a condition of being overweight/obese on short-term functional recovery as evaluated by the "time to permitted load" could be explained by a mediator variable (type of hip fracture). We studied 727 women aged 60 years or over with a recent low trauma surgically treated hip fracture and for whom an information on post-surgery complications and on the time to permitted load was available. To assess for mediation, the statistical analyses were carried out following the procedure described by Baron and Kenny. In this study, 46 % of women with hip fracture presented a time to permitted load of ≥ 10 days. The women with a post-surgery time to permitted load of ≥ 10 days showed a significantly higher proportion of trochanteric fracture localization (72.1 vs 42 %), of total overweight/obesity (46.5 vs 36.8 %) and of post-surgery complications (38.8 vs 18.8 %). The mediating effect of hip fracture localization on the association between overweight/obesity and the time of permitted load was demonstrated and confirmed in a multivariate logistic regression model. This study, carried out using a "mediator" statistical analysis, suggests that in elderly women with hip fracture being overweight/obese is associated with a slower short-term functional recovery as evaluated by the time to permitted load and that this association is mediated by the trochanteric localization of hip fracture.

    Full Text Available Short-term traffic flow prediction is an important part of intelligent transportation systems research and applications. For further improving the accuracy of short-time traffic flow prediction, a novel hybrid prediction model (multivariate phase space reconstruction–combined kernel function-least squares support vector machine based on multivariate phase space reconstruction and combined kernel function-least squares support vector machine is proposed. The C-C method is used to determine the optimal time delay and the optimal embedding dimension of traffic variables’ (flow, speed, and occupancy time series for phase space reconstruction. The G-P method is selected to calculate the correlation dimension of attractor which is an important index for judging chaotic characteristics of the traffic variables’ series. The optimal input form of combined kernel function-least squares support vector machine model is determined by multivariate phase space reconstruction, and the model’s parameters are optimized by particle swarm optimization algorithm. Finally, case validation is carried out using the measured data of an expressway in Xiamen, China. The experimental results suggest that the new proposed model yields better predictions compared with similar models (combined kernel function-least squares support vector machine, multivariate phase space reconstruction–generalized kernel function-least squares support vector machine, and phase space reconstruction–combined kernel function-least squares support vector machine, which indicates that the new proposed model exhibits stronger prediction ability and robustness.

    Urea cycle disorders (UCDs) are a group of rare inherited metabolic disorders. Affected individuals often present with hyperammonemic encephalopathy (HE) and have an increased risk of severe neurologic disease and early death. The study aims to provide epidemiologic data and to describe the disease manifestation and short-term outcome. Cross-border surveillance of newly diagnosed patients with UCDs - below 16 years of age - was performed from July 2012 to June 2015 in Germany and Austria and from January 2012 to December 2015 in Switzerland. Inquiries were sent monthly to all Pediatric Departments in Germany and Switzerland, and quarterly to the Austrian Metabolic Group. In addition, data were collected via a second source (metabolic laboratories) in all three countries. Between July 2012 and June 2015, fifty patients (Germany: 39, Austria: 7, Switzerland: 4) with newly diagnosed UCDs were reported and later confirmed resulting in an estimated cumulative incidence of 1 in 51,946 live births. At diagnosis, thirty-nine patients were symptomatic and 11 asymptomatic [10 identified by newborn screening (NBS), 1 by high-risk-family screening (HRF)]. The majority of symptomatic patients (30 of 39 patients) developed HE with (n = 25) or without coma (n = 5), 28 of them with neonatal onset. Despite emergency treatment 15 of 30 patients with HE already died during the newborn period. Noteworthy, 10 of 11 patients diagnosed by NBS or HRF remained asymptomatic. Comparison with the European registry and network for intoxication type metabolic diseases (E-IMD) demonstrated that cross-national surveillance identified a higher number of clinically severe UCD patients characterized by earlier onset of symptoms, higher peak ammonium concentrations in plasma and higher mortality. Cross-border surveillance is a powerful tool to identify patients with UCDs demonstrating that (1) the cumulative incidence of UCDs is lower than originally suggested, (2) the mortality rate is still

    2017-01-01

    Objectives: The primary goal of this study was to assess the short-term outcomes among National Football League (NFL) players following concussion in terms of: (1) DNP protocol activation, (2) release rate at one and three years, and (3) mean salary reduction. A secondary goal of the study was to stratify the post-concussive release rate by franchise and player position. Methods: NFL player transaction records and publicly available weekly injury reports from August 2005 to January 2016 for NFL players were analyzed. All players immediately sustaining recorded concussions were evaluated for a change to inactive or do-not-play (DNP) status. The one-year and three-year release rate following concussion was defined as any player transitioning to inactivation, retirement, free agency, or any failure to return for a successive season on the same team’s active roster after one or three years from the initial concussion. Student’s t-test was used to compare release rates between non-concussed and concussed players at one and three years. Mean salary reduction per year following concussion was calculated using publicly available player contracts. Additionally, franchise-level and position-based analyses of the release rate were performed. Results: Of the total 5,451 NFL players retrospectively analyzed over the 11-year period, 373 sustained publicly reported concussions resulting in DNP protocol activation. The release rate of the post-concussive versus non-concussive player was 26% vs. 20% at 1 year (pfranchise to release an athlete following concussion within one and three years. Table 1 reports a position-based analysis in terms of concussion rate, mean salary reduction, and NFL career longevity. Conclusion: Our retrospective study demonstrates that NFL concussions resulting in DNP protocol activation leads to a statistically greater release rate among concussed NFL players than non-concussed players. Released players suffered reduction in year-over-year accumulated

    Full Text Available The extraction of minerals from land-based mines necessitates the disposal of large amounts of mine tailings. Dumping and storage of tailings into the marine environment, such as fjords, is currently being performed without knowing the potential ecological consequences. This study investigated the effect of short-term exposure to different deposition depths of inert iron ore tailings (0.1, 0.5, and 3 cm and dead subsurface sediment (0.5 and 3 cm on a deep water (200 m fjord benthic assemblage in a microcosm experiment. Biotic and abiotic variables were measured to determine structural and functional changes of the benthic community following an 11 and 16 day exposure with tailings and dead sediment, respectively. Structural changes of macrofauna, meiofauna, and bacteria were measured in terms of biomass, density, community composition and mortality while measures of oxygen penetration depth, sediment community oxygen consumption and 13C-uptake and processing by biota revealed changes in the functioning of the system. Burial with mine tailings and natural sediments modified the structure and functioning of the benthic community albeit in a different way. Mine tailings deposition of 0.1 cm and more resulted in a reduced capacity of the benthic community to remineralize fresh 13C-labeled algal material, as evidenced by the reduced sediment community oxygen consumption and uptake rates in all biological compartments. At 3 cm of tailings deposition, it was evident that nematode mortality was higher inside the tailings layer, likely caused by reduced food availability. In contrast, dead sediment addition led to an increase in oxygen consumption and bacterial carbon uptake comparable to control conditions, thereby leaving deeper sediment layers anoxic and in turn causing nematode mortality at 3 cm deposition. This study clearly shows that even small levels (0.1 cm of instantaneous burial by mine tailings may significantly reduce benthic ecosystem

    Full Text Available Abstract Background As the first meal of the day, breakfast plays an important role in supplying energy and nutrients, which are critical to working and learning activities. A three-phase crossover study was designed to investigate the effects of breakfast on cognitive function among Chinese white-collar workers. The planned study protocol is presented. Methods A total of 264 participants aged 25–45 years will be recruited from Shenyang and Chongqing. Self-administered questionnaires will be used to collect information on age, gender, marital status, education level, occupation, smoking habits, drinking habits, and breakfast behaviours. The participants will be randomly assigned to 3 equal-sized groups (Groups A, B, and C and will be provided with a nutrition-adequate breakfast, a nutrition-inadequate breakfast, or no breakfast, respectively. Each participant will receive the breakfast treatment on the basis of assignment to one of three sequences (ABC/BCA/CAB. Each participant will complete a battery of cognitive tests assessing short-term memory, attention, and working memory 120 minutes after breakfast. Mood will be measured through a self-administered questionnaire assessing the dimensions of positive and negative frames of mind. Additionally, fasting blood glucose and postprandial 2-hour blood glucose levels will be tested with a blood-glucose meter (Roche ACCU-CHEK®-Performa. All the participants will take all the tests in three successive weeks, and the order of presentation will be counter-balanced across groups. Discussion The present study will be the first investigation of the effect of breakfast food type and quality on cognitive function amongst white-collar workers in China. We predict that a nutrition-adequate breakfast, compared with a nutrition-inadequate breakfast and no breakfast, will significantly improve short-term cognitive function. The results of this study should provide scientific evidence of the effect of

  20. Using ecological momentary assessment to investigate short-term variations in sexual functioning in a sample of peri-menopausal women from Iran.

    Full Text Available The investigation of short-term changes in female sexual functioning has received little attention so far. The aims of the study were to gain empirical knowledge on within-subject and within- and across-variable fluctuations in women's sexual functioning over time. More specifically, to investigate the stability of women´s self-reported sexual functioning and the moderating effects of contextual and interpersonal factors. A convenience sample of 206 women, recruited across eight Health care Clinics in Rasht, Iran. Ecological momentary assessment was used to examine fluctuations of sexual functioning over a six week period. A shortened version of the Female Sexual Function Index (FSFI was applied to assess sexual functioning. Self-constructed questions were included to assess relationship satisfaction, partner's sexual performance and stress levels. Mixed linear two-level model analyses revealed a link between orgasm and relationship satisfaction (Beta = 0.125, P = 0.074 with this link varying significantly between women. Analyses further revealed a significant negative association between stress and all six domains of women's sexual functioning. Women not only reported differing levels of stress over the course of the assessment period, but further differed from each other in how much stress they experienced and how much this influenced their sexual response. Orgasm and sexual satisfaction were both significantly associated with all other domains of sexual function (P<0.001. And finally, a link between partner performance and all domains of women`s sexual functioning (P<0.001 could be detected. Except for lubrication (P = 0.717, relationship satisfaction had a significant effect on all domains of the sexual response (P<0.001. Overall, our findings support the new group of criteria introduced in the DSM-5, called "associated features" such as partner factors and relationship factors. Consideration of these criteria is important and necessary for

    Results from randomised controlled trials have shown a higher short-term risk of stroke associated with carotid stenting than with carotid endarterectomy for the treatment of symptomatic carotid stenosis. However, these trials were underpowered for investigation of whether carotid artery stenting might be a safe alternative to endarterectomy in specific patient subgroups. We therefore did a preplanned meta-analysis of individual patient data from three randomised controlled trials. Data from all 3433 patients with symptomatic carotid stenosis who were randomly assigned and analysed in the Endarterectomy versus Angioplasty in Patients with Symptomatic Severe Carotid Stenosis (EVA-3S) trial, the Stent-Protected Angioplasty versus Carotid Endarterectomy (SPACE) trial, and the International Carotid Stenting Study (ICSS) were pooled and analysed with fixed-effect binomial regression models adjusted for source trial. The primary outcome event was any stroke or death. The intention-to-treat (ITT) analysis included all patients and outcome events occurring between randomisation and 120 days thereafter. The per-protocol (PP) analysis was restricted to patients receiving the allocated treatment and events occurring within 30 days after treatment. In the first 120 days after randomisation (ITT analysis), any stroke or death occurred significantly more often in the carotid stenting group (153 [8·9%] of 1725) than in the carotid endarterectomy group (99 [5·8%] of 1708, risk ratio [RR] 1·53, [95% CI 1·20-1·95], p=0·0006; absolute risk difference 3·2 [1·4-4·9]). Of all subgroup variables assessed, only age significantly modified the treatment effect: in patients younger than 70 years (median age), the estimated 120-day risk of stroke or death was 50 (5·8%) of 869 patients in the carotid stenting group and 48 (5·7%) of 843 in the carotid endarterectomy group (RR 1·00 [0·68-1·47]); in patients 70 years or older, the estimated risk with carotid stenting was twice that

    The effect of eye blinks on short-term memory was examined in two experiments. On each trial, participants viewed an initial display of coloured, oriented lines, then after a retention interval they viewed a test display that was either identical or different by one feature. Participants kept their eyes open throughout the retention interval on some blocks of trials, whereas on others they made a single eye blink. Accuracy was measured as a function of the number of items in the display to determine the capacity of short-term memory on blink and no-blink trials. In separate blocks of trials participants were instructed to remember colour only, orientation only, or both colour and orientation. Eye blinks reduced short-term memory capacity by approximately 0.6-0.8 items for both feature and conjunction stimuli. A third, control, experiment showed that a button press during the retention interval had no effect on short-term memory capacity, indicating that the effect of an eye blink was not due to general motoric dual-task interference. Eye blinks might instead reduce short-term memory capacity by interfering with attention-based rehearsal processes.

    Full Text Available Aim. The galactose single-point (GSP test assesses functioning liver mass by measuring the galactose concentration in the blood 1 hour after its administration. The purpose of this study was to investigate the impact of hemodialysis (HD on short-term and long-term liver function by use of GSP test. Methods. Seventy-four patients on maintenance HD (46 males and 28 females, 60.38 ± 11.86 years with a mean time on HD of 60.77 ± 48.31 months were studied. The GSP values were compared in two groups: (1 before and after single session HD, and (2 after one year of maintenance HD. Results. Among the 74 HD patient, only the post-HD Cr levels and years on dialysis were significantly correlated with GSP values (r=0.280, P<0.05 and r=-0.240, P<0.05, resp.. 14 of 74 patients were selected for GSP evaluation before and after a single HD session, and the hepatic clearance of galactose was similar (pre-HD 410 ± 254 g/mL, post-HD 439 ± 298 g/mL, P=0.49. GSP values decreased from 420.20 ± 175.26 g/mL to 383.40 ± 153.97 g/mL after 1 year maintenance HD in other 15 patients (mean difference: 19.00 ± 37.66 g/mL, P<0.05. Conclusions. Patients on maintenance HD for several years may experience improvement of their liver function. However, a single HD session does not affect liver function significantly as assessed by the GSP test. Since the metabolism of galactose is dependent on liver blood flow and hepatic functional mass, further studies are needed.

    Objective: To explore the effects of gadopentetate dimeglumine injection on renal function. Methods: The study included 623 consecutive patients. Their serum creatinine concentrations before and within 3 days after injection of gadopentetate dimeglumine were analyzed. Their eGFR (estimated glomerular filtration rate) were calculated. Patients were divided into two groups according to their injection dose: group received single dose and group received double dose. Patients in each group were subdivided into three subgroups according to their eGFR: subgroup of normal renal function, subgroup of mild renal insufficiency and subgroup of moderate renal insufficiency. Paried sample t test and group design paired sample Rank Sum test were used for statistical analysis. Results: There was no adverse reaction or occurrence of acute renal insufficiency. The mean level of serum creatinine dropped from (74.0± 17.2) μmol/L to (71.5±19.0) μmol/L (t=5.39, P 0.05) in subgroup of mild renal insufficiency under group received double dose and increased from (118.3±15.3) μmol/L to (135.7±8.5) μmol/L (t=2.02, P<0.05) in subgroup of moderate renal insufficiency under group received double dose, the mean level of serum creatinine dropped in all other subgroups. Conclusions: Single dose gadopentetate dimeglumine is safe for patients with normal renal function and mild, moderate renal insufficiency in short term, but patients with abnormal renal function should be followed up after double dose injection.

    The aim of the study was to evaluate the positive effects of combination of several physiotherapy methods on the respiratory function on example of a case report. 14 years old girl with an adolescent idiopathic scoliosis (AIS), right thoracic (primary curve, Cobb angle = 40°, AVR = 12°) and left lumbar (secondary curve, Cobb angle = 33°, AVR = 24°) participated in the study. She was 2 years after menarche. She underwent stationary (in-patient) treatment for 3 weeks with use of standard medical care (DoboMed). Treatment also included manual therapy (OMT Kaltenborn-Evjenth) and Dynamic Brace System (DBC) device, produced by Meditrack. Then she continued exercises at home. Respiratory system function was analyzed with use of SpiroPro electronic spirometer (Jaeger) and the strength of respiratory muscles with use of portable digital pressure meter equipped with the Omega PX 25 ± 35 kPa pressure transducer. Range of movement of the spine was examined with Rippstein V plurimeter, angle of apical trunk rotation (ATR) with the Bunnell scoliometer. Measurement was performed 4 times: before treatment, after one week and 3 weeks after the beginning of the treatment and 3 months after finalization of the treatment period. Examination showed that DoboMed medical care treatment, manual therapy and use of DBC device in period of 3 weeks caused improvement of respiratory parameters (MIP - maximal inspiration pressure by 6.7%; MEP - maximal expiratory pressure by 12.6%, PEF - peak expiratory flow by 16.1%). Spinal range of lateral movement and angle of apical trunk rotation has also improved. In short term treatment, the manual therapy aided with DBC system has improved the respiratory parameters and trunk morphology values. Such a composition of various physiotherapy methods can help to conduct further specialized exercises of DoboMed method.

    Sports-related concussions and repetitive subconcussive exposure are increasingly recognized as potential dangers to paediatric populations, but much remains unknown about the short-term and long-term consequences of these events, including potential cognitive impairment and risk of later-life dementia. This Expert Consensus Document is the result of a 1-day meeting convened by Safe Kids Worldwide, the Alzheimer's Drug Discovery Foundation, and the Andrews Institute for Orthopaedics and Sports Medicine. The goal is to highlight knowledge gaps and areas of critically needed research in the areas of concussion science, dementia, genetics, diagnostic and prognostic biomarkers, neuroimaging, sports injury surveillance, and information sharing. For each of these areas, we propose clear and achievable paths to improve the understanding, treatment and prevention of youth sports-related concussions.

    Postoperative nosocomial infection (PNI) is a severe complication in surgical patients. Known risk factors of PNI such as allogeneic blood transfusions (ABTs), anemia, and iron deficiency are manageable with perioperative intravenous (IV) iron therapy. To address potential concerns about IV iron and the risk of PNI, we studied a large series of orthopedic surgical patients for possible relations between IV iron, ABT, and PNI. Pooled data on ABT, PNI, 30-day mortality, and length of hospital stay (LHS) from 2547 patients undergoing elective lower-limb arthroplasty (n = 1186) or hip fracture repair (n = 1361) were compared between patients who received either very-short-term perioperative IV iron (200-600 mg; n = 1538), with or without recombinant human erythropoietin (rHuEPO; 40,000 IU), or standard treatment (n = 1009). Compared to standard therapy, perioperative IV iron reduced rates of ABT (32.4% vs. 48.8%; p = 0.001), PNI (10.7% vs. 26.9%; p = 0.001), and 30-day mortality (4.8% vs. 9.4%; p = 0.003) and the LHS (11.9 days vs. 13.4 days; p = 0.001) in hip fracture patients. These benefits were observed in both transfused and nontransfused patients. Also in elective arthroplasty, IV iron reduced ABT rates (8.9% vs. 30.1%; p = 0.001) and LHS (8.4 days vs.10.7 days; p = 0.001), without differences in PNI rates (2.8% vs. 3.7%; p = 0.417), and there was no 30-day mortality. Despite known limitations of pooled observational analyses, these results suggest that very-short-term perioperative administration of IV iron, with or without rHuEPO, in major lower limb orthopedic procedures is associated with reduced ABT rates and LHS, without increasing postoperative morbidity or mortality. © 2013 American Association of Blood Banks.

    Full Text Available Background/Aim. Hip arthroplasty is a routine operation which relieves pain in patients with osteoarthritis. The role of physical therapy after hip arthroplasty was recognized, but the importance of preoperative physical therapy and education is still to be judged. The aim of this paper was to investigate the effect of short-term preoperative program of education and physical therapy on patients' early functional recovery immediately after total hip arthroplasty (THA. Methods. This prospective study included 45 patients with hip osteoarthritis scheduled to undergo primary THA and admitted to the Department of Orthopedics of Military Medical Academy. They were randomized into 2 groups: study and control one (with and without preoperative education and physical therapy. Preoperative education was conducted through conversation (1 appointment with physiatrist and brochure. The study group was instructed to perform exercises and basic activities from the postoperative rehabilitation program (2 practical classes with physiotherapist. Effects were measured with questionnaires (Harris, Oxford and Japanese Orthopaedic Association (JOA hip scores, range of motion and visual analog scale of pain. Marks showing ability to perform basic activities and endurance were from 0 (did not perform activity to 5 (independent and secure. Analyses examined differences between the groups over the preoperative and immediate postoperative periods and 15 months after the operation. Results. There were no differences between the groups at discharge according to pain, range of motion, Harris hip score and JOA hip score. Oxford hip score did not differ between the groups 15 months after the operation.

    The aim of the study was to determine whether thyroid hormones level on admission in patients with ischemic stroke, treated with intravenous recombinant tissue type plasminogen activator (rtPA), was associated with symptomatic intracranial hemorrhage (sICH) and worse outcomes at 3 months.Patients with acute ischemic stroke (AIS) receiving intravenous rtPA thrombolytic treatment on our stroke unit between January 2015 and June 2016 were included in this study. Serum-free triiodothyronine (fT3), free thyroxine (fT4), total triiodothyronine (tT3), total thyroxine (tT4), and thyroid-stimulating hormone (TSH) were detected on admission. The endpoints were sICH, and poor functional outcomes at 3 and 6 months.In all, 159 patients (106 males; mean age 65.36 ± 10.02 years) were included. FT3 was independently associated with sICH (odds ratio [OR] 0.204, 95% confidence interval [CI] 0.065-0.642) and poor outcomes at 3 months (OR 0.396, 95% CI 0.180-1.764). The cut-off values of fT3 for sICH was 3.54 pg/mL (sensitivity 83%; specificity 83%; area under the curve 0.88). FT3 values ≤3.54 pg/mL increased risk for sICH by 3.16-fold (95% CI 0.75-1.0) compared with fT3 values >3.54 pg/mL.Low fT3 levels at admission were independently associated with sICH and worse outcomes at 3 months in AIS patients receiving rtPA thrombolytic therapy.

    Full Text Available Electroconvulsive therapy (ECT is effective in the treatment of treatment-resistant major depression. The fear of cognitive impairment after ECT often deters patients from choosing this treatment option. There is little reliable information regarding the effects of ECT on overall cognitive performance, while short-term memory deficits are well known but not easy to measure within clinical routines. In this pilot study, we examined ECT recipients’ pre- and posttreatment performances on a digital ascending number tapping test. We found that cognitive performance measures exhibited good reproducibility in individual patients and that ECT did not significantly alter cognitive performance up to 2 hours after this therapy was applied. Our results can help patients and physicians make decisions regarding the administration of ECT. Digital measurements are recommended, especially when screening for the most common side effects on cognitive performance and short-term memory.

    Enucleation is increasingly used for pancreatic solid pseudopapillary neoplasm (SPN) to preserve function of the pancreas. The data was limited due to rarity of this low-grade neoplasm. We sought to describe the indications, operative technique, short and long-term outcomes after enucleation with largest series of enucleated SPNs. Data collected retrospectively from 110 patients with SPN who underwent pancreatectomy between 2009 and 2016 in our institution were reviewed. Thirty-one patients underwent enucleation were identified for analysis, and compared with the 70 patients underwent conventional pancreatic resection. Of the 31 patients, 27 (87.1%) were women, and the mean age was 29.8 years (range, 11-49 years). Enucleated SPNs were mostly located in the head/uncinate process of the pancreas (38.7%). Overall morbidity was 25.8%, mainly due to POPF (19.4%), and severe morbidity was only 6.5% with no death. Compared with conventional pancreatic resection, enucleation had a shorter duration of surgery (P insufficiency (P = 0.033) and comparable morbidity (P = 1), with no increased risk of tumor recurrence (P = 1). The rate of endocrine insufficiency after enucleation seemed lower (Nil vs. 4.5%, P = 0.55). Enucleation of SPN of the pancreas appears to be feasible and safe for preserving exocrine and endocrine function of the gland. Enucleation with negative surgical margin seems adequate with no increased risk of tumor recurrence. Enucleation could be seriously considered as an alternative to conventional resection for this frequently young population. Copyright © 2018. Published by Elsevier Ltd.

    The EEG is considered as building block of functional signaling in the brain. The role of EEG oscillations in human information processing has been intensively investigated. To study the quantitative EEG correlates of short term memory load as assessed through Sternberg memory test. The study was conducted on 34 healthy male student volunteers. The intervention consisted of Sternberg memory test, which runs on a version of the Sternberg memory scanning paradigm software on a computer. Electroencephalography (EEG) was recorded from 19 scalp locations according to 10-20 international system of electrode placement. EEG signals were analyzed offline. To overcome the problems of fixed band system, individual alpha frequency (IAF) based frequency band selection method was adopted. The outcome measures were FFT transformed absolute powers in the six bands at 19 electrode positions. Sternberg memory test served as model of short term memory load. Correlation analysis of EEG during memory task was reflected as decreased absolute power in Upper alpha band in nearly all the electrode positions; increased power in Theta band at Fronto-Temporal region and Lower 1 alpha band at Fronto-Central region. Lower 2 alpha, Beta and Gamma band power remained unchanged. Short term memory load has distinct electroencephalographic correlates resembling the mentally stressed state. This is evident from decreased power in Upper alpha band (corresponding to Alpha band of traditional EEG system) which is representative band of relaxed mental state. Fronto-temporal Theta power changes may reflect the encoding and execution of memory task.

  20. Impact of Obstructive Sleep Apnea on the Levels of Placental Growth Factor (PlGF and Their Value for Predicting Short-Term Adverse Outcomes in Patients with Acute Coronary Syndrome.

    Full Text Available Placental growth factor (PlGF induces angiogenesis and promotes tissue repair, and plasma PlGF levels change markedly during acute myocardial infarction (AMI. Currently, the impact of obstructive sleep apnea (OSA in patients with AMI is a subject of debate. Our objective was to evaluate the relationships between PlGF levels and both the severity of acute coronary syndrome (ACS and short-term outcomes after ACS in patients with and without OSA.A total of 538 consecutive patients (312 OSA patients and 226 controls admitted for ACS were included in this study. All patients underwent polygraphy in the first 72 hours after hospital admission. The severity of disease and short-term prognoses were evaluated during the hospitalization period. Plasma PlGF levels were measured using an electrochemiluminescence immunoassay.Patients with OSA were significantly older and more frequently hypertensive and had higher BMIs than those without OSA. After adjusting for age, smoking status, BMI and hypertension, PlGF levels were significantly elevated in patients with OSA compared with patients without OSA (19.9 pg/mL, interquartile range: 16.6-24.5 pg/mL; 18.5 pg/mL, interquartile range: 14.7-22.7 pg/mL; p1, even after adjustment.The results of this study show that in patients with ACS, elevated plasma levels of PlGF are associated with the presence of OSA and with adverse outcomes during short-term follow-up.ClinicalTrials.gov NCT01335087.

    We aimed to evaluate whether potential changes in the patient's illness perception can significantly influence short-term seizure burden following video-electroencephalography (EEG) confirmation/explanation of psychogenic nonepileptic seizures (PNES). Patients with PNES were dichotomized to two groups based on a five-point Symptom Attribution Scale: (a) those who prior to diagnosis perceived their seizures to be solely ("5") or mainly ("4") physical in origin (physical group) and (b) the remainder of patients with PNES (psychological group). The physical group (n=32), psychological group (n=40), and group with epilepsy (n=26) also completed the Brief Illness Perception Questionnaire (BIPQ) prior to diagnosis, and were followed up at 3months as well as at 6months postdiagnosis. At 3months postdiagnosis, the physical group experienced significantly greater improvement in seizure intensity (p=0.002) and seizure frequency (p=0.016) when compared with the psychological group. The physical group was significantly more likely to have modified their symptom attribution toward a greater psychological role to their seizures (p=0.002), and their endorsement on the BIPQ item addressing "consequences" (How much do your seizures affect your life?) was significantly less severe (p'=0.014) when compared with that of the psychological group and the group with epilepsy. At 6months postdiagnosis, the physical group continued to experience significantly greater improvement in seizure intensity (p=0.007) while their seizure frequency no longer reached significant difference (p=0.078) when compared with the psychological group. The physical group continued to be significantly more likely to have modified their symptom attribution toward a greater psychological role to their seizures (p=0.005), and their endorsement on the BIPQ item addressing "consequences" remained significantly less severe (p'=0.037) when compared with the psychological group and the group with epilepsy.

    To compare the performance of iohexol plasma clearance and creatinine-based renal function estimating equations in monitoring longitudinal renal function changes in chronic heart failure (CHF) patients, and to assess the effects of body composition on the equation performance. Iohexol plasma clearance was measured in 43 CHF patients at baseline and after at least 6 months. Simultaneously, renal function was estimated with five creatinine-based equations (four- and six-variable Modification of Diet in Renal Disease, Cockcroft-Gault, Cockcroft-Gault adjusted for lean body mass, Chronic Kidney Disease Epidemiology Collaboration equation) and body composition was assessed using bioimpedance and dual-energy x-ray absorptiometry. Over a median follow-up of 7.5 months (range 6-17 months), iohexol clearance significantly declined (52.8 vs 44.4 mL/[min ×1.73 m2], P=0.001). This decline was significantly higher in patients receiving mineralocorticoid receptor antagonists at baseline (mean decline -22% of baseline value vs -3%, P=0.037). Mean serum creatinine concentration did not change significantly during follow-up and no creatinine-based renal function estimating equation was able to detect the significant longitudinal decline of renal function determined by iohexol clearance. After accounting for body composition, the accuracy of the equations improved, but not their ability to detect renal function decline. Renal function measured with iohexol plasma clearance showed relevant decline in CHF patients, particularly in those treated with mineralocorticoid receptor antagonists. None of the equations for renal function estimation was able to detect these changes. ClinicalTrials.gov registration number: NCT01829880.

    Objective: To evaluate the effectiveness of the Ponseti method of clubfoot management in neonates and infants and to see which factors affect outcome. Study Design: Retrospective study. Place and Duration of Study: Department of Paediatric surgery, Military Hospital, Rawalpindi, from October 2012 to September 2014. Material and Methods: The Ponseti method for the management of congenital talipes equinovarus was applied in children of 7 days to 6 months age. While those with complex neurological problems, pathological clubfeet, syndromic clubfeet and older than 6 months at the time of presentation were excluded from the study. Assessment was done at presentation, at the removal of the last plaster cast and after one-year use of the foot abduction splint. Results: A total of 124 clubfeet of 89 children, including 63 males (70.78 percent) and 26 females (43.82 percent) were treated as outdoor cases. Eighteen feet (14.51 percent) were of rigid (atypical) type whilst 106 (85.5 percent) were of flexible (typical) type. Bilateral involvement was seen in 35(37.31 percent) children. The mean pretreatment Pirani score was 5.4 and the mean number of plaster casts required was 5.8. The mean Pirani score at 1-year follow-up was 0.5 with successful outcome in 82.3 percent of all cases (96.9 percent of neonates). Poor compliance with the use of the foot abduction splint adversely affected outcomes. Conclusion: The Ponseti method of treatment of congenital clubfeet is safe and easy to learn with effective and reproducible results. Early start of treatment and compliance with the use of the foot abduction splint during the maintenance phase are crucial to successful outcome. (author)

    Opiate addiction is associated with decision-making deficits and we previously showed that the extent of these impairments predicts aspects of treatment outcome. Here we aimed to establish whether measures of decision-making performance might be used to inform placement matching. Two groups of opiate dependent individuals, one receiving treatment in a community setting (n=48) and one in a residential setting (n=32) were administered computerised tests of decision-making, impulsivity and planning shortly after the beginning of treatment, to be followed up three months into each programme. In the community sample, performance on the decision-making tasks at initial assessment predicted abstinence from illicit drugs at follow-up. In contrast, in the residential sample there was no relationship between decision-making and clinical outcome. Intact decision-making processes appear to be necessary for upholding a resolve to avoid taking drugs in a community setting, but the importance of these mechanisms may be attenuated in a residential treatment setting. The results support the placement matching hypothesis, suggesting that individuals with more prominent decision-making deficits may particularly benefit from treatment in a residential setting and from the inclusion of aspects of cognitive rehabilitation in their treatment programme.

    Randomized, controlled trials have demonstrated the superiority of sirolimus-eluting stent (SES) implantation during primary percutaneous coronary intervention (PCI), as opposed to bare-metal stents, in patients with ST-elevation myocardial infarction (STEMI). This study aimed to test the hypothesis that clinical benefits of SES treatment were independent of gender in this setting. A total of 2042 patients with STEMI undergoing SES-based primary PCI were prospectively enrolled into Shanghai Acute Coronary Event (SACE) registry (1574 men and 468 women). Baseline demographics, angiographic and PCI features, and in-hospital and 30-day major adverse cardiac events (MACE) were analyzed as a function of gender. Compared with men, women were older and more frequently had hypertension, diabetes, and hypercholesterolemia. Use of platelet glycoprotein IIb/IIIa receptor inhibitor (GPI, 65.5% vs. 62.2%, P = 0.10) and procedural success rate (95.0% vs. 94.2%, P = 0.52) were similar in both genders. In-hospital death and MACE occurred in 3.8% and 7.6%, and 4.5% and 8.1% in the male and female patients, respectively (all P > 0.05). At 30-day follow-up, survival (94.3% vs. 93.8%, P = 0.66) and MACE-free survival (90.2% vs. 89.3%, P = 0.52) did not significantly differ between men and women. After adjustment for differences in patient demographics, angiographic and procedural features, there were no significant difference in either in-hospital (OR = 0.77, 95%CI of 0.48 to 1.22, P = 0.30) or 30-day mortality (OR = 1.28, 95%CI of 0.73 to 2.23, P = 0.38) between women and men. Despite more advanced age and clustering of risk factors in women, female patients with STEMI treated by SES-based primary PCI had similar in-hospital and short-term clinical outcomes as their male counterparts.

    Full Text Available Myocardial dysfunction is a major complication in cardiac surgery that needs inotropic support. This study evaluates the effect of milrinone on patients with low ventricular ejection fraction undergoing off- pump coronary artery bypass graft (OPCAB. The present study is designed to evaluate the effect of milrinone on myocardial dysfunction. Eighty patients with low ventricular ejection fraction (<35%, candidate for elective OPCAB, were enrolled in this study. They were randomly assigned to two groups. One group received milrinone (50 μg/kg intravenously and another group received a saline as placebo followed by 24 hours infusion of each agent (0.5 μg/kg/min. Short outcome of patients such as hemodynamic parameters and left ventricular ejection fraction were variables evaluated. Serum levels of creatine phosphokinase, the MB isoenzyme of creatine kinase, occurrence of arrhythmias and mean duration of mechanical ventilation were significantly lower in milrinone group (P<0.05. The mean post operative left ventricular ejection fraction was significantly higher in milrinone group (P=0.031. There were no statistical significant differences between the two groups in terms of intra-aortic balloon pump, inotropic support requirement, myocardial ischemia, myocardial infarction, duration of inotropic support, duration of intensive care unit stay, mortality and morbidity rate. Administration of milrinone in patients undergoing OPCAB with low ventricular ejection fraction is useful and effective.

    The long-term oncologic stability of laparoscopic surgery for colon cancer was established, and laparoscopic surgery was accepted as an alternative to conventional open surgery for colon cancer. However, transverse colon cancer was excluded from the majority of the previous prospective studies. As a result, debate on laparoscopic surgery for transverse colon cancer continues. This study aimed to compare the clinicopathologic outcome of laparoscopic surgery with that of conventional open surgery for transverse colon cancer. From August 2004 to December 2007, 106 cases of transverse colon cancer were managed by resection at our institution, and 89 of these cases were included in this study. Age, sex, body mass index (BMI), operation time, blood loss, time to first flatus, time to start of diet, hospital stay, complications, tumor size, distal resection margin, proximal resection margin, and number of nodes harvested were compared between the two groups. No significant differences were found between the laparoscopic and conventional groups in terms of age, sex, BMI, operation time, or hospital stay. The mean blood loss during the operations was significantly less in the laparoscopic group (113.8 +/- 128.9 ml) than in the conventional group (278.8 +/- 268.7 ml; p transverse colon cancer, and the oncologic quality of laparoscopic surgery was found to be acceptable compared with conventional open surgery.

    Full Text Available Endogenously produced inhibitors of nitric oxide (NO synthase, in particular asymmetric dimethylarginine (ADMA, are currently considered of importance in various disease states characterized by reduced NO availability. We investigated the association between plasma levels of ADMA, symmetric dimethylarginine (SDMA, l-arginine, and citrulline and perinatal factors and outcome in 130 preterm (gestational age ≤30 weeks very low birth weight (VLBW, <1500 g infants. Plasma samples were collected 6–12 h after birth. We did not find significant correlations between ADMA, SDMA, l-arginine, and citrulline levels and gestational age or birth weight. However, the arginine:ADMA ratio (AAR, a better indicator of NO availability than either arginine or ADMA separately was positively correlated with gestational age. ADMA and arginine levels were not significantly different between males and females but males showed a negative correlation between ADMA levels and gestational age. Perinatal factors such as preeclampsia, chrorioamnionitis, prolonged rupture of membranes, or form of delivery did not significantly alter dimethylarginine levels or AAR. In contrast, the AAR was significantly reduced in the infants with respiratory distress, mechanical ventilation, and systemic hypotension Therefore, our data suggest that altered NO availability may play a role in the respiratory and cardiovascular adaptation in preterm VLBW infants.

    Recently, mid-urethral slings have been commonly used in treatment of patients with stress urinary incontinence (SUI). To investigate tension-free vaginal tape (TVT) and tension-free obturator tape (TVT-O) for surgical treatment of SUI for cure rates (primary endpoint), complications and factors influencing cure rate (secondary endpoints). One-hundred and sixty-four patients were included in the study (n = 81 for TVT, n = 83 for TVT-O). The cure rates, complications, preoperative and postoperative urodynamic evaluation, Q-tip test, the Turkish version of Incontinence Impact Questionnaire (IIQ-7) and Urogenital Distress Inventory (UDI-6) scores were recorded. At three and 12 months, the patients were evaluated regarding outcome measures. The cure rates were similar in TVT and TVT-O groups, 88.9% versus 86.7% respectively. Mean operative time was significantly shorter in TVT-O group (P = 0.001). The cure rate was significantly higher in both groups in patients with urethral hypermobility when compared with those with no hypermobility (P = 0.001). The TVT and TVT-O procedures appear to be equally effective for the treatment of SUI. Also, urethral hypermobility seems to be a factor influencing cure rate of mid-urethral slings.

    Background Minimally invasive surgery has been recently recommended for treatment of early-stage non-small cell lung cancer. Despite the recent increase of robotic surgery, the place and potential advantages of the robot in thoracic surgery has not been well defined until now. Methods We reviewed our prospective database for retrospective comparison of our first 28 video-assisted thoracoscopic surgery lobectomies (V group) and our first 28 robotic lobectomies (R group). Results No significant difference was shown in median operative time between the two groups (185 vs. 190 minutes, p = 0.56). Median preincision time was significantly longer in the R group (80 vs. 60 minutes, P < 0.0001). The rate of emergency conversion for uncontrolled bleeding was lower in the R group (one vs. four). Median length of stay was comparable (6 days in the R group vs. 7 days in the V group, p = 0.4) with no significant difference in the rate of postoperative complications (eight Grade I in both groups, four Grade III or IV in the V group vs. six in the R group, according to the Clavien-Dindo classification, p = 0.93). No postoperative cardiac morbidity was observed in the R group. Median drainage time was similar (5 days, p = 0.78), with a rate of prolonged air leak slightly higher in the R group (25 vs. 17.8%, p = 0.74). Conclusion Perioperative outcomes are similar even in the learning period but robotic approach seems to offer more operative safety with fewer conversions for uncontrolled bleeding.

    The goal of treatment for patients with synchronous liver metastases (SLM) from rectal cancer is to achieve a complete resection of both tumor locations. For patients with symptomatic locally advanced rectal cancer with resectable SLM at diagnosis, our usual strategy has been the rectum first approach (RF). However, since 2014, we advocate for the interval approach (IS) that involves the administration of chemo-radiotherapy followed by the resection of the SLM in the interval of time between rectal cancer radiation and rectal surgery. From 2010 to 2016, 16 patients were treated according to this new strategy and 19 were treated according RF strategy. Data were collected prospectively and analyzed with an intention-to-treat perspective. Complete resection rate, duration of the treatment and morbi-mortality were the main outcomes. The complete resection rate in the IS was higher (100%, n = 16) compared to the RF (74%, n = 14, p = 0.049) and the duration of the strategy was shorter (6 vs. 9 months, respectively, p = 0.006). The incidence of severe complications after liver surgery was 14% (n = 2) in the RF and 0% in the IS (p = 1.000), and after rectal surgery was 24% (n = 4) and 12% (n = 2), respectively (p = 1.000). The IS is a feasible and safe strategy that procures higher level of complete resection rate in a shorter period of time compared to RF strategy.

    We analysed the gross motor recovery of infants and toddlers with cyanotic and acyanotic congenital heart disease (CHD) who received early postoperative physical therapy to see whether there was any difference in the duration to recovery. This study retrospectively evaluated the influence of early physical therapy on postoperative gross motor outcomes of patients with CHD. The gross motor ability of patients with cyanotic (n = 25, average age: 376.4 days) and acyanotic (n = 26, average age: 164.5 days) CHD was evaluated using our newly developed nine-grade mobility assessment scale. Physical therapy was started at an average of five days after surgery, during which each patient's gross motor ability was significantly decreased compared with the preoperative level. Patients (who received early postoperative physical therapy) with cyanotic (88.0%) and acyanotic CHD (96.2%) showed improved preoperative mobility grades by the time of hospital discharge. However, patients with cyanotic CHD had a significantly prolonged recovery period compared to those with acyanotic CHD (p congenital heart disease are likely at greater risk of gross motor delays and have a prolonged recovery period of gross motor ability compared to those with acyanotic congenital heart disease. Early postoperative physical therapy for patients with congenital heart disease after cardiac surgery promoted gross motor recovery. The postoperative recovery period to preoperative mobility grade was affected by pre-, intra-, and postoperative factors. Rehabilitation experts should consider the risk of gross motor delays of patients with congenital heart disease after cardiac surgery and the early postoperative physical therapy to promote their gross motor recovery.

    The aim of this study was to evaluate functional recovery in a subgroup of hip fracture patients who sustained a simultaneous fracture at the upper limb, taking into account the site of upper limb injury. Of 760 patients admitted consecutively to the authors' rehabilitation hospital because of a fall-related hip fracture, 700 were retrospectively investigated. Functional outcome was assessed using Barthel Index scores. In 49 of the 700 patients, a single fall resulted in both a hip fracture and a fracture of either wrist (n = 34) or proximal humerus (n = 15). The patients with concomitant shoulder fractures had lower median Barthel Index scores after rehabilitation (70 vs. 90, P = 0.003), lower median Barthel Index effectiveness (57.1 vs. 76.9, P = 0.018), and prolonged median length of stay (42 vs. 36 days, P = 0.011) than did the patients with isolated hip fractures. Significant differences persisted after adjustment for six potential confounders. The adjusted odds ratio for achieving a Barthel Index score lower than 85 was 6.71 (95% confidence interval, 1.68-26.81; P = 0.007) for the patients with concomitant shoulder fractures. Conversely, no prognostic disadvantages were associated with concomitant wrist fractures. Data show a worse functional recovery and a prolonged length of stay in the subgroup of hip fracture patients who sustained a concomitant fracture at the proximal humerus, but not at the wrist.

    Menstrual low back pain (LBP) in young females can reduce daily activity and cause functional disability, while the progressive application of kinesio-taping (KT) on pain reduction and functional correction has been stated. This study has been designed to investigate the efficacy of the lumbar vertebral column KT in young female with menstrual LBP. Thirty-two young females with menstrual LBP participated in this crossover study and were assigned randomly in two separate groups. The first group received KT during their first menstrual cycle and No-KT in their next menstrual, while the other group had no KT during the first mentrual cycle and received KT during the next menstrual cycle. The primary outcome measurements included the visual analogue scale (VAS) of pain, Oswestry disability index and McGill pain questionnaire score which were planned to collect at the end of the third day of the menstrual cycle. Comparing pain and disability between two conditions, of menstrual cycle with KT and menstrual cycle without KT, revealed significant reduction in VAS (mean change = 1.7; 95%CI = 0.6 to 2.8; P= 0.005), McGill pain score (mean change = 20.1; 95%CI = 8.7 to 31.3; P= 0.001) and functional disability (mean change = 12.3; 95%CI = 7.2 to 17.5; Pkinesiotaping in young females with menstrual LBP.

    To evaluate the short-term outcomes and quality of life (QoL) in gastric cancer patients undergoing digestive tract construction using the isoperistaltic jejunum-later-cut overlap method (IJOM) after totally laparoscopic total gastrectomy (TLTG). A total of 507 patients who underwent laparoscopic gastrectomy (D2) from January 2014 to March 2016 were originally included in the study. The patients were divided into two groups to undergo digestive tract construction using either IJOM after TLTG (group T, n = 51) or Roux-en-Y anastomosis after laparoscopic-assisted total gastrectomy (LATG) (group A, n = 456). The short-term outcomes and QoL were compared between the two groups after 1:2 propensity-score matching (PSM). We used a questionnaire to assess QoL. Before matching, age, sex, tumor size, tumor location, preoperative albumin and blood loss were significantly different between the two groups ( P < 0.05). After PSM, the patients were well balanced in terms of their clinicopathological characteristics, although both blood loss and in-hospital postoperative days in group T were significantly lower than those in group A ( P < 0.05). After matching, group T reported better QoL in the domains of pain and dysphagia. Among the items evaluating pain and dysphagia, group T tended to report better QoL ("Have you felt pain" and "Have you had difficulty eating solid food") ( P < 0.05). The IJOM for digestive tract reconstruction after TLTG is associated with reduced blood loss and less pain and dysphagia, thus improving QoL after laparoscopic gastrectomy.

    We aimed to investigate whether the lung-to-thorax transverse area ratio (LTR) immediately before birth is of diagnostic value for the prediction of postnatal short-term outcomes in cases of isolated left-sided congenital diaphragmatic hernia (CDH). We retrospectively reviewed the cases of fetal isolated left-sided CDH managed at our institution between April 2008 and July 2016. We divided the patients into two groups based on LTR immediately before birth, using a cut-off value of 0.08. We compared the proportions of subjects within the two groups who survived until discharge using Fisher's exact test. Further, using Spearman's rank correlation, we assessed whether LTR was correlated with length of stay, duration of mechanical ventilation, and supplemental oxygen. Twenty-nine subjects were included (five with LTR < 0.08, and 24 with LTR ≥ 0.08). The proportion of subjects surviving until discharge was 40% (2/5) for patients with LTR < 0.08, as compared with 96% (23/24) for those with LTR ≥ 0.08. LTR measured immediately before birth was negatively correlated with the postnatal length of stay (Spearman's rank correlation coefficient, rs = -0.486), and the duration of supplemental oxygen (rs = -0.537). Further, the duration of mechanical ventilation was longer in patients with a lower LTR value. LTR immediately before birth is useful for the prediction of postnatal short-term outcomes in fetuses with isolated left-sided CDH. In particular, patients with prenatal LTR value less than 0.08 are at increased risk of postnatal death. © 2017 Japanese Teratology Society.

    To compare efficacy and safety of visual internal urethrotomy (VIU) using holmium laser (Ho:YAG) (group A) versus cold knife (group B) in children with urethral strictures. It may be the first comparative study on this issue in children. This study compared Ho:YAG group, which was evaluated prospectively from January 2014 till January 2016, versus cold knife group, which was a historical control performed from March 2008 till February 2010. Children ≤ 13 years old with urethral strictures ≤ 1.5 cm were included successively. Recurrent cases, congenital obstructions and cases with complete arrest of dye in voiding cystourethrography were excluded. Scar tissue was incised at twelve o'clock. Outcome was compared using Student's t, Mann-Whitney, Chi-square or Fisher exact tests as appropriate. Each group included 21 patients. Mean age was 6.27 ± 3.23 (2-13) years old. Mean stricture length was 1.02 versus 1 cm in group A versus B, respectively (p = 0.862). Ten cases of penile/bulbous strictures and another 11 cases of membranous strictures were found in each group. There was no significant difference between both groups in preoperative data. Success rate for initial VIU was 66.7% in group A versus 38% in group B (p = 0.064). This was associated with significantly higher Q max in group A (mean 16.52 vs 12.09 ml/s; p = 0.03). Success rate after two trials of VIU was 76.2% for group A and 47.61% for group B (p = 0.057). No complications were reported in both groups. Laser VIU has a higher success rate than cold knife VIU for urethral strictures ≤ 1.5 cm in children with significantly higher Q max . Both are easy to perform, low invasive and safe.

    Onboard Short Term Plan Viewer (OSTPV) is a computer program for electronic display of mission plans and timelines, both aboard the International Space Station (ISS) and in ISS ground control stations located in several countries. OSTPV was specifically designed both (1) for use within the limited ISS computing environment and (2) to be compatible with computers used in ground control stations. OSTPV supplants a prior system in which, aboard the ISS, timelines were printed on paper and incorporated into files that also contained other paper documents. Hence, the introduction of OSTPV has both reduced the consumption of resources and saved time in updating plans and timelines. OSTPV accepts, as input, the mission timeline output of a legacy, print-oriented, UNIX-based program called "Consolidated Planning System" and converts the timeline information for display in an interactive, dynamic, Windows Web-based graphical user interface that is used by both the ISS crew and ground control teams in real time. OSTPV enables the ISS crew to electronically indicate execution of timeline steps, launch electronic procedures, and efficiently report to ground control teams on the statuses of ISS activities, all by use of laptop computers aboard the ISS.

    This study investigated whether increasing insoluble (predominantly wheat bran) fibre over 14 days improves subjective digestive feelings, general wellbeing and bowel function. A single centre, multi-site, open, within subjects design with a 14 day non-intervention (baseline) monitoring period followed by a 14 day fibre consumption (intervention) period was performed. 153 low fibre consumers (breakfast cereal containing at least 5.4 g fibre (3.5 g from wheat bran) for 14 days and completed a daily symptom diary. Significant improvements were demonstrated in subjective perception of bowel function (e.g., ease of defecation) and digestive feelings (bloating, constipation, feeling sluggish and digestive discomfort). Significant improvements were also found in subjective perception of general wellbeing (feeling less fat, more mentally alert, slim, happy and energetic whilst experiencing less stress, mental and physical tiredness, difficulty concentrating and fewer headaches). In general, improvements in study outcomes increased with increasing cereal/fibre consumption. However, consuming an additional minimum 5.4 g of fibre (3.5 g wheat bran) per day was shown to deliver measurable and significant benefits for digestive health, comfort and wellbeing. Encouraging consumption of relatively small amounts of wheat bran could also provide an effective method of increasing overall fibre consumption.

    Full Text Available Chronic face pain syndrome is a diagnostic and therapeutic problem for many specialists, and this proves the interdisciplinary and complex nature of this ailment. Physiotherapy is of particular importance in the treatment of pain syndrome in the course of temporomandibular joint functional disorders. In patients with long-term dysfunction of masticatory muscles, the palpation examination can localize trigger points, that is, thickening in the form of nodules in the size of rice grains or peas. Latent trigger points located in the muscles can interfere with muscular movement patterns, cause cramps, and reduce muscle strength. Because hidden trigger points can spontaneously activate, they should be found and released to prevent further escalation of the discomfort. Kinesiotaping (KT is considered as an intervention that can be used to release latent myofascial trigger points. It is a method that involves applying specific tapes to the patient’s skin in order to take advantage of the natural self-healing processes of the body. The aim of the study was to evaluate the effect of the kinesiotaping method and trigger points inactivation on the nonpharmacological elimination of pain in patients with temporomandibular disorders. The study was conducted in 60 patients (18 to 35 years old. The subjects were randomly divided into two subgroups of 30 people each. Group KT (15 women and 15 men were subjected to active kinesiotaping application. Group TrP, composed of 16 women and 14 men, was subjected to physiotherapy with the release of trigger points by the ischemic compression method. The results show that the KT method and TrP inactivation brought significant therapeutic analgesic effects in the course of pain-related functional disorders of the muscles of mastication. The more beneficial outcomes of the therapy were observed after using the KT method, which increased the analgesic effect in dysfunctional patients.

    relative to the low T condition. In both age groups, high T increased watching time of threatening social stimuli in the Social Playbacks. These results suggest that T affects some aspects of emotional processing but has no effect on fine motor function or cognition in young or older male macaques. It is possible that the duration of T treatment was not long enough to affect cognition or fine motor function or that T levels were too high to improve these outcomes. An alternative explanation for the discrepancies of our findings with some of the cognitive and emotional effects of T reported in rodents and humans may be the use of a chemical castration, which reduced circulating gonadotropins in addition to T. Further studies will investigate whether the luteinizing hormone LH mediates the effects of T on brain function in male primates. Copyright © 2014 Elsevier Inc. All rights reserved.

  11. Short term depression unmasks the ghost frequency.

    Tjeerd V Olde Scheper

    Full Text Available Short Term Plasticity (STP has been shown to exist extensively in synapses throughout the brain. Its function is more or less clear in the sense that it alters the probability of synaptic transmission at short time scales. However, it is still unclear what effect STP has on the dynamics of neural networks. We show, using a novel dynamic STP model, that Short Term Depression (STD can affect the phase of frequency coded input such that small networks can perform temporal signal summation and determination with high accuracy. We show that this property of STD can readily solve the problem of the ghost frequency, the perceived pitch of a harmonic complex in absence of the base frequency. Additionally, we demonstrate that this property can explain dynamics in larger networks. By means of two models, one of chopper neurons in the Ventral Cochlear Nucleus and one of a cortical microcircuit with inhibitory Martinotti neurons, it is shown that the dynamics in these microcircuits can reliably be reproduced using STP. Our model of STP gives important insights into the potential roles of STP in self-regulation of cortical activity and long-range afferent input in neuronal microcircuits.

    Converging lines of evidence suggest that auditory system short-term plasticity can enable several perceptual and cognitive functions that have been previously considered as relatively distinct phenomena. Here we review recent findings suggesting that auditory stimulation, auditory selective attention and cross-modal effects of visual stimulation each cause transient excitatory and (surround) inhibitory modulations in the auditory cortex. These modulations might adaptively tune hierarchically organized sound feature maps of the auditory cortex (e.g. tonotopy), thus filtering relevant sounds during rapidly changing environmental and task demands. This could support auditory sensory memory, pre-attentive detection of sound novelty, enhanced perception during selective attention, influence of visual processing on auditory perception and longer-term plastic changes associated with perceptual learning.

    The objectives are to analyze the technical success rate as well as the short-term and long-term complications of totally implantable venous access ports (TIVAPs) at the forearm. Retrospective analysis of 1,704 consecutively implanted TIVAPs was performed. Primary endpoints were defined as technical success rate, clinical outcome, device service interval, and rates of major complications. Minor complications not requiring port explantation were defined as secondary endpoints. The technical success rate was 99.2 % with no major complications. During follow-up, a total of 643,200 catheter-days were documented, the mean device service interval was 380.6 days/patient. A total of 243 complications (14.4 %) in 226 patients were observed (0.4/1000 catheter-days), in 140 patients (8.3 %) the port device had to be explanted. Disconnection between the port device and the catheter (1.6 %) was more frequent than fracture (0.8 %) and leakage (0.6 %) of the catheter, which occurred more frequently when the catheter was inserted via the cephalic versus the brachial vein. TIVAP implantation at the forearm is a simple and safe procedure with a low rate of early and late complications. (orig.)

Background: Limited studies are available on alteration in LV hemodynamics, especially diastolic function, after PDA closure. Methods: Thirty-two consecutive children with isolated PDA treated by trans-catheter closure were studied. The LV systolic and diastolic function were assessed by two-dimensional (2D echocardiography and tissue Doppler imaging 1 day before the PDA closure, on day 1, and on follow-up. Results: At baseline, none of the patients had LV systolic dysfunction. On day 1 post-PDA closure, 8 (25% children developed LV systolic dysfunction. The baseline LV ejection fraction (LVEF, LV end-systolic dimension (LVESD, and PDA diastolic gradient predicted the post-closure LVEF. Patients who developed post-closure LV systolic dysfunction had poorer LV diastolic function than those who did not. LV diastolic properties improved after PDA closure; however, the improvement in LV diastolic properties lagged behind the improvement in the LV systolic function. All children were asymptomatic and had normal LVEF on follow up of >3 months. Conclusions: Percutaneous closure of PDA is associated with the reversible LV systolic dysfunction. Improvement in the LV diastolic function lags behind that in the LV systolic function.

This selection of variables resulted in a sub-sample of 138,098 participants after discarding extreme values. A digit triplets functional hearing test was used to divide the participants into three groups: poor, insufficient and normal hearers. We found negative relationships between functional hearing loss and both visuospatial working memory (i.e., a card pair matching task) and visuospatial, episodic long-term memory (i.e., a prospective memory task), with the strongest association for episodic long-term memory. The use of hearing aids showed a small positive effect for working memory performance for the poor hearers, but did not have any influence on episodic long-term memory. Age also showed strong main effects for both memory tasks and interacted with gender and education for the long-term memory task. Broader theoretical implications based on a memory systems approach will be discussed and compared to theoretical alternatives.

    The main objective of short term load forecasting (STLF) is to provide load predictions for generation scheduling, economic load dispatch and security assessment at any time. The STLF is needed to supply necessary information for the system management of day-to-day operations and unit commitment. In this paper, the 'time' and 'temperature' of the day are taken as inputs for the fuzzy logic controller and the 'forecasted load' is the output. The input variable 'time' has been divided into eight triangular membership functions. The membership functions are Mid Night, Dawn, Morning, Fore Noon, After Noon, Evening, Dusk and Night. Another input variable 'temperature' has been divided into four triangular membership functions. They are Below Normal, Normal, Above Normal and High. The 'forecasted load' as output has been divided into eight triangular membership functions. They are Very Low, Low, Sub Normal, Moderate Normal, Normal, Above Normal, High and Very High. Case studies have been carried out for the Neyveli Thermal Power Station Unit-II (NTPS-II) in India. The fuzzy forecasted load values are compared with the conventional forecasted values. The forecasted load closely matches the actual one within +/-3%. (author)

    Osteoarthritis (OA) is a highly prevalent, chronic, degenerative condition that generates a high expense. Alternative and co-adjuvant therapies to improve the quality of life and physical function of affected patients are currently being sought. A total of 808 patients with knee pathology were treated with PRGF (plasma rich in growth factors), 312 of them with OA of the knee (Outerbridge grades I-IV) and symptoms of >3 months duration met the inclusion criteria and were evaluated to obtain a sample of 261 patients, 109 women and 152 men, with an average age of 48.39. Three intra-articular injections of autologous PRGF were administered at 2-week intervals in outpatient surgery. The process of obtaining PRGF was carried out following the Anitua Technique. Participants were asked to fill out a questionnaire with personal data and the following assessment instruments: VAS, SF-36, WOMAC Index and Lequesne Index before the first infiltration of PRGF and 6 months after the last infiltration. Statistically significant differences (P PRGF infiltration. At 6 months following intra-articular infiltration of PRGF in patients with OA of the knee, improvements in function and quality of life were documented by OA-specific and general clinical assessment instruments. These favourable findings point to consider PRGF as a therapy for OA.

    To investigate whether patient quality of life and sexual function are improved after the tension-free vaginal tape SECUR (TVT-S) procedure (H-type). Prospective study (Canadian Task Force classification II-3). Single-center hospital. Thirty-three women with stress urinary incontinence (SUI) (high urethral mobility) and no concomitant pelvic floor prolapse underwent TVT-S between October 2009 and October 2011. TVT-S procedure. Before and after surgery(6 and 12 months), all patients completed the Chinese version of the Incontinence Quality of Life Questionnaire (I-QOL). In addition, 28 sexually active patients who underwent the TVT-S procedure completed the short-form Pelvic Organ Prolapse/Urinary Incontinence Sexual Function Questionnaire (PISQ-12) before and after surgery (6 and 12 months). We used a paired t test to compare I-QOL scores before and after surgery. The Wilcoxon signed-rank test was used to compare the preoperative and postoperative PISQ scores. The objective cure rate was 78% (26 of 33 patients) at 12 months after surgery. The objective improvement rate was 12.1% (4 of 33 patients). The subjective satisfaction rate was 90%. Three operations (9.1%) were considered failures. Two patients underwent a TVT procedure after TVT-S because of recurrence. No patients reported severe pain; the mean (SD) visual analog scale pain score was 1.8 (1.2) after surgery. Only 1 patient (3%) was found to have sling erosion at 12 months postoperatively. The I-QOL score was 28.3 (14.2) before surgery and increased to 69.5 (18.9) at 12 months after the TVT-S procedure. The I-QOL score improved significantly after surgery (p .05). Although the objective cure rate was not high, the TVT-S procedure is a minimally invasive, safe, and effective surgical procedure for treatment of SUI (high urethral mobility) and can improve the quality of life and sexual function in women with SUI.

    Aim: To assess changes in ventricular size and function over time in conservatively treated adult patients with repaired tetralogy of Fallot (TOF) and significant pulmonary regurgitation (PR). Materials and methods: Patients with repaired TOF who had undergone more than one cardiac magnetic resonance study were identified. To confine the cause of ventricular size and function deviation to PR, patients with residual ventricular septal defect, more than mild regurgitation at a valve other than the pulmonary valve, and known coronary artery disease were excluded. Results: The final analysis included 27 adults with PR fraction >20%. During a follow-up of mean 2.1 ± 0.8 years, there was no change in right ventricular (RV) end-diastolic volume (EDV; 162.1 ± 27.6 versus 164 ± 29.6 ml/m 2 , p = 0.5). Left ventricular (LV) EDV showed a small decrease (85.1 ± 16.2 versus 81.5 ± 14.1 ml/m 2 , p = 0.02). The mean PR fraction, PR volume, and peak RV outflow tract gradient did not change. Additionally, both RV ejection fraction (EF) and LVEF remained stable over the follow-up period (48.1 ± 6.5 versus 48.4 ± 6.7%, p = 0.83, and 57.3 ± 5.4 versus 57.2 ± 5.1 %, p = 0.91, respectively). Only two asymptomatic patients (7.4% of the study group) developed symptoms and the remaining did not deteriorate. Conclusion: The RVEDV, RVEF, and LVEF remained stable over a mean follow-up of approximately 2 years in the majority of adult patients after TOF repair with significant PR and a wide range of RVEDV

    Biochar sequesters carbon (C) in soils because of its prolonged residence time, ranging from several years to millennia. In addition, biochar can promote indirect C-sequestration by increasing crop yield while, potentially, reducing C-mineralization. This laboratory study was set up to evaluate effects of biochar on C-mineralization with due attention to source appointment by using 13 C isotope signatures. An arable soil (S) (7.9 g organic C, OC kg −1 ) was amended (single dose of 10 g kg −1 soil) with dried, grinded maize stover (leaves and stalks), either natural (R) or 13 C enriched (R*), and/or biochar (B/B*) prepared from the maize stover residues (450 °C). Accordingly, seven different combinations were set up (S, SR, SB, SR*, SB*, SRB*, SR*B) to trace the source of C in CO 2 (180 days), dissolved organic-C (115 days) and OC in soil aggregate fractions (90 days). The application of biochar to soil reduced the mineralization of native soil organic C but the effect on maize stover-C mineralization was not consistent. Biochar application decreased the mineralization of the non-enriched maize stover after 90 days, this being consistent with a significant reduction of dissolved organic C concentration from 45 to 18 mg L −1 . However, no significant effect was observed for the enriched maize stover, presumably due to differences between the natural and enriched materials. The combined addition of biochar and enriched maize stover significantly increased (twofold) the presence of native soil organic C or maize derived C in the free microaggregate fraction relative to soil added only with stover. Although consistent effects among C sources and biochar materials remains elusive, our outcomes indicate that some biochar products can reduce mineralization and solubilization of other sources of C while promoting their physical protection in soil particles. - Highlights: • Biochar can reduce native soil organic carbon mineralization. • Biochar can promote storage

    To determine whether hyaluronic acid (HA) injection into rheumatoid arthritis ankles and feet can achieve improvement in foot function and reduce synovial hyper-vascularization. Forty-four patients with RA having unilateral or bilateral painful ankle and foot involvement (N = 75) were studied. All the patients were randomized to receive HA (N = 40) or lidocaine (LI) (N = 35) injection at 2-week intervals; Clinical assessments were performed using a visual analog scale (VAS) and foot function index (FFI total ) including subscales of pain (FFI pain) before injection at baseline, 4 weeks (first evaluation) and 12 weeks (secondary evaluation). Imaging evaluation based on color Doppler ultrasound (CDUS) and synovitis scores was performed simultaneously. HA injection improved the VAS score (p = .009), FFI pain (p = .041), and FFI total (p = .032) considerably more than LI injections did at the first evaluation. The CDUS values at first evaluation (p = .005) and secondary evaluation (p injections reduced the CDUS values of more than half of the joints (54%, p = .042) while the control group exhibited no change (20%, p = .56). However, HA injection did not reduce the CDUS values more than LI injection did. Regarding the evaluation of synovial hypertrophy, no significant difference was observed between or within the groups in the synovitis scores. HA injection improved short-term foot function and pain reduction. HA injection may have a modest effect in reducing synovial hyper-vascularization. Further large-scale study is warranted to confirm this result.

    This study investigated whether the relationship between muscle torque and m-waves remained constant after short recovery periods, between repeated intervals of isometric muscle contractions induced by functional electrical stimulation (FES). Eight subjects with spinal cord injury (SCI) were recruited for the study. All subjects had their quadriceps muscles group stimulated during three sessions of isometric contractions separated by 5 min of recovery. The evoked-electromyographic (eEMG) signals, as well as the produced torque, were synchronously acquired during the contractions and during short FES bursts applied during the recovery intervals. All analysed m-wave variables changed progressively throughout the three contractions, even though the same muscle torque was generated. The peak to peak amplitude (PtpA), and the m-wave area (Area) were significantly increased, while the time between the stimulus artefact and the positive peak (PosT) were substantially reduced when the muscles became fatigued. In addition, all m-wave variables recovered faster and to a greater extent than did torque after the recovery intervals. We concluded that rapid recovery intervals between FES-evoked exercise sessions can radically interfere in the use of m-waves as a proxy for torque estimation in individuals with SCI. This needs to be further investigated, in addition to seeking a better understanding of the mechanisms of muscle fatigue and recovery. PMID:25479324

    Full Text Available Short-term maintenance of verbal information is a core factor of language repetition, especially when reproducing multiple or unfamiliar stimuli. Many models of language processing locate the verbal short-term maintenance function in the left posterior superior temporo-parietal area and its connections with the inferior frontal gyrus. However, research in the field of short-term memory has implicated bilateral fronto-parietal networks, involved in attention and serial order processing, as being critical for the maintenance and reproduction of verbal sequences. We present here an integrative framework aimed at bridging research in the language processing and short-term memory fields. This framework considers verbal short-term maintenance as an emergent function resulting from synchronized and integrated activation in dorsal and ventral language processing networks as well as fronto-parietal attention and serial order processing networks. To-be-maintained item representations are temporarily activated in the dorsal and ventral language processing networks, novel phoneme and word serial order information is proposed to be maintained via a right fronto-parietal serial order processing network, and activation in these different networks is proposed to be coordinated and maintained via a left fronto-parietal attention processing network. This framework provides new perspectives for our understanding of information maintenance at the nonword-, word- and sentence-level as well as of verbal maintenance deficits in case of brain injury.

    The amount of information that can be stored in visual short-term memory is strictly limited to about four items. Therefore, memory capacity relies not only on the successful retention of relevant information but also on efficient suppression of distracting information, visual attention, and executive functions. However, completely separable neural signatures for these memory capacity-limiting factors remain to be identified. Because of its functional diversity, oscillatory brain activity may offer a utile solution. In the present study, we show that capacity-determining mechanisms, namely retention of relevant information and suppression of distracting information, are based on neural substrates independent of each other: the successful maintenance of relevant material in short-term memory is associated with cross-frequency phase synchronization between theta (rhythmical neural activity around 5 Hz) and gamma (> 50 Hz) oscillations at posterior parietal recording sites. On the other hand, electroencephalographic alpha activity (around 10 Hz) predicts memory capacity based on efficient suppression of irrelevant information in short-term memory. Moreover, repetitive transcranial magnetic stimulation at alpha frequency can modulate short-term memory capacity by influencing the ability to suppress distracting information. Taken together, the current study provides evidence for a double dissociation of brain oscillatory correlates of visual short-term memory capacity.

    Five groups of albino male rats, every group consist of seven rats, were used to study the effect of microwave proteins on liver, kidney functions and blood parameters. Control group was fed on 10% casein. The 2nd one was fed on 10% protein from microwave chicken. The 3rd one was fed on 10% protein from boiled chicken. The 4th one was fed on 10% protein from microwave kidney beans. The 5th one was fed on 10% protein from boiled kidney beans. The time of experiment was seven weeks. The biochemical parameters included (cholesterol, LDL, HDL, total lipids, triglyceride, SGOT, SGPT, ALP, creatinin, uric acid and amino acids). The group of rats fed on microwave chicken showed more increase in cholesterol level than the group fed on boiled chicken. The group fed on microwave kidney beans showed decrease in cholesterol level. The group fed on microwave chicken showed decrease in HDL and increase in LDL. The highest activity of SGOT was shown in group fed on microwave kidney beans followed by the group fed on microwave chicken. The groups fed on boiled kidney beans and boiled chicken proteins showed significant increase in SGPT activity. The group fed on boiled kidney beans have the highest activity of ALP enzyme; but the group fed on microwave chicken showed increase in the activity of ALP enzyme compared to the control group. The feeding of microwave chicken leads to increase in creatinine and uric acid levels in comparison to the control group. Microwave cooking leads to little increase in all amino acids in comparison to the control group

Patients were propensity-matched to AMI patients with no evidence of GI bleed from the same US health plan.Results: 12,437 upper GI-bleed patients and 22,847 AMI patients were identified. Propensity score matching yielded 6,923 matched pairs. Matched cohorts were found to have a similar Charlson Comorbidity Index score and to be similar on nearly all utilization and cost measures (excepting emergency room costs. A comparison of outcomes among the matched cohorts found that AMI patients had higher rates of 30-day mortality (4.35% vs 2.54%; p < 0.0001 and rehospitalization (2.56% vs 1.79%; p = 0.002, while GI bleed patients were more likely to have a repeat procedure (72.38% vs 44.95%; p < 0.001 following their initial hospitalization. The majority of the difference in overall 30-day mortality between GI bleed and AMI patients was accounted for by mortality during the initial hospitalization (1.91% vs 3.58%.Conclusions: GI bleeding events result in significant mortality similar to that of an AMI after adjusting for the initial hospitalization.Keywords: gastrointestinal, bleeding, mortality, acute myocardial infarction, claims analysis

    Associative memory using fast weights is a short-term memory mechanism that substantially improves the memory capacity and time scale of recurrent neural networks (RNNs). As recent studies introduced fast weights only to regular RNNs, it is unknown whether fast weight memory is beneficial to gated RNNs. In this work, we report a significant synergy between long short-term memory (LSTM) networks and fast weight associative memories. We show that this combination, in learning associative retrie...

    Both the Acute physiology and Chronic Health Evaluation (APACHE II) score and mean platelet volume/platelet count Ratio (MPR) can independently predict adverse outcomes in critically ill patients. This study was aimed to investigate whether the combination of them could have a better performance in predicting prognosis of patients with acute kidney injury (AKI) who received continuous renal replacement therapy (CRRT). Two hundred twenty-three patients with AKI who underwent CRRT between January 2009 and December 2014 in a Chinese university hospital were enrolled. They were divided into survivals group and non-survivals group based on the situation at discharge. Receiver Operating Characteristic (ROC) curve was used for MPR and APACHE II score, and to determine the optimal cut-off value of MPR for in-hospital mortality. Factors associated with mortality were identified by univariate and multivariate logistic regression analysis. The mean age of the patients was 61.4 years, and the overall in-hospital mortality was 48.4%. Acute cardiorenal syndrome (ACRS) was the most common cause of AKI. The optimal cut-off value of MPR for mortality was 0.099 with an area under the ROC curve (AUC) of 0.636. The AUC increased to 0.851 with the addition of the APACHE II score. The mortality of patients with of MPR > 0.099 was 56.4%, which was significantly higher than that of the control group with of ≤ 0.099 (39.6%, P= 0.012). Logistic regression analysis showed that average number of organ failure (OR = 2.372), APACHE II score (OR = 1.187), age (OR = 1.028) and vasopressors administration (OR = 38.130) were significantly associated with poor prognosis. Severity of illness was significantly associated with prognosis of patients with AKI.

    Full Text Available Abstract Background Factors associated with the loss of participants in long-term longitudinal studies of ageing, due to refusal or moves, have been discussed less than those with short term follow-up. Methods In a population-based study of cognition and ageing (the Medical Research Council Cognitive Function and Ageing Study (MRC CFAS, factors associated with dropout due to refusal and moving in the first follow-up period (over two years are compared with factors associated with dropout over ten years. Participants at 10-year follow-up are compared with their age-standardised baseline contemporaries. Results Some consistent trends are found over the longer term. Refusers tended to have poorer cognition, less years of education, not have a family history of dementia and be women. Characteristics of people who moved differed between waves, but the oldest and people in worse health moved more. When surviving and responding individuals at ten years are compared with those of the same age at baseline many differences are found. Individuals of lower social class, education, cognitive ability, in residential care, with sight/hearing problems and poor/fair self-reported health are less likely to be seen after 10 years of follow-up. Individuals report more health problems when they participate in multiple interviews. Conclusion The characteristics of refusers in the longer term are similar to those refusing to participate over the shorter term. Long-term follow-up studies will under represent the disadvantaged and disabled but represent full health status of participating individuals better. There are advantages and disadvantages to both short-term and long-term follow-up.

    2011-01-01

    As of writing in mid-2010, both Landsat-5 and -7 continue to function, with sufficient fuel to enable data collection until the launch of the Landsat Data Continuity Mission (LDCM) scheduled for December of 2012. Failure of one or both of Landsat-5 or -7 may result in a lack of Landsat data for a period of time until the 2012 launch. Although the potential risk of a component failure increases the longer the sensor's design life is exceeded, the possible gap in Landsat data acquisition is reduced with each passing day and the risk of Landsat imagery being unavailable diminishes for all except a handful of applications that are particularly data demanding. Advances in Landsat data compositing and fusion are providing opportunities to address issues associated with Landsat-7 SLC-off imagery and to mitigate a potential acquisition gap through the integration of imagery from different sensors. The latter will likely also provide short-term, regional solutions to application-specific needs for the continuity of Landsat-like observations. Our goal in this communication is not to minimize the community's concerns regarding a gap in Landsat observations, but rather to clarify how the current situation has evolved and provide an up-to-date understanding of the circumstances, implications, and mitigation options related to a potential gap in the Landsat data record.

  4. Pigeon visual short-term memory directly compared to primates.

    Three pigeons were trained to remember arrays of 2-6 colored squares and detect which of two squares had changed color to test their visual short-term memory. Procedures (e.g., stimuli, displays, viewing times, delays) were similar to those used to test monkeys and humans. Following extensive training, pigeons performed slightly better than similarly trained monkeys, but both animal species were considerably less accurate than humans with the same array sizes (2, 4 and 6 items). Pigeons and monkeys showed calculated memory capacities of one item or less, whereas humans showed a memory capacity of 2.5 items. Despite the differences in calculated memory capacities, the pigeons' memory results, like those from monkeys and humans, were all well characterized by an inverse power-law function fit to d' values for the five display sizes. This characterization provides a simple, straightforward summary of the fundamental processing of visual short-term memory (how visual short-term memory declines with memory load) that emphasizes species similarities based upon similar functional relationships. By closely matching pigeon testing parameters to those of monkeys and humans, these similar functional relationships suggest similar underlying processes of visual short-term memory in pigeons, monkeys and humans.

    Colorectal resections are common surgical procedures all over the world. Laparoscopic colorectal surgery is technically feasible in a considerable amount of patients under elective conditions. Several short-term benefits of the laparoscopic approach to colorectal resection (less pain, less morbidity, improved reconvalescence and better quality of life) have been proposed. This review compares laparoscopic and conventional colorectal resection with regards to possible benefits of the laparoscopic method in the short-term postoperative period (up to 3 months post surgery). We searched MEDLINE, EMBASE, CancerLit, and the Cochrane Central Register of Controlled Trials for the years 1991 to 2004. We also handsearched the following journals from 1991 to 2004: British Journal of Surgery, Archives of Surgery, Annals of Surgery, Surgery, World Journal of Surgery, Disease of Colon and Rectum, Surgical Endoscopy, International Journal of Colorectal Disease, Langenbeck's Archives of Surgery, Der Chirurg, Zentralblatt für Chirurgie, Aktuelle Chirurgie/Viszeralchirurgie. Handsearch of abstracts from the following society meetings from 1991 to 2004: American College of Surgeons, American Society of Colorectal Surgeons, Royal Society of Surgeons, British Assocation of Coloproctology, Surgical Association of Endoscopic Surgeons, European Association of Endoscopic Surgeons, Asian Society of Endoscopic Surgeons. All randomised-controlled trial were included regardless of the language of publication. No- or pseudorandomised trials as well as studies that followed patient's preferences towards one of the two interventions were excluded, but listed separately. RCT presented as only an abstract were excluded. Results were extracted from papers by three observers independently on a predefined data sheet. Disagreements were solved by discussion. 'REVMAN 4.2' was used for statistical analysis. Mean differences (95% confidence intervals) were used for analysing continuous variables. If

    A modified tier 1 Endocrine Disruptor Screening Program (EDSP) 21-d fish short-term reproduction assay (FSTRA) was used to evaluate the effects of sediment exposure from freshwater and brackish ponds in Bermuda on reproductive fecundity and endocrine function in fathead minnow (Pimephales promelas) and killifish (Fundulus heteroclitus). Reproductively active male and female fish were exposed to control sediment and sediment from 2 freshwater ponds (fathead minnow) and 2 marine ponds (killifish) contaminated with polyaromatic hydrocarbons and metals via flow-through exposure for 21 d. Reproductive fecundity was monitored daily. At termination, the status of the reproductive endocrine system was assessed by the gonadosomatic index, gonadal histology, plasma steroids (estrogen [E2], testosterone [T], and 11-ketotestosterone [11-KT]), steroidogenic enzymes (aromatase and combined 3β/17β -hydroxysteroid dehydrogenase [3β/17β-HSD]), and plasma vitellogenin (VTG). Decreased reproductive fecundity, lower male body weight, and altered endocrinological measures of reproductive status were observed in both species. Higher plasma T levels in female minnows and 11-KT levels in both male and female minnows and female killifish exposed to freshwater and brackish sediments, respectively. Decreased female E2 and VTG levels and gonadal cytochrome P19 (aromatase) activity were also found in sediment exposed females from both species. No effect on female 3β/17β-HSD activity was found in either species. The FSTRA provided a robust model capable of modification to evaluate reproductive effects of sediment exposure in fish. © 2015 SETAC.

    The aim of this study was to quantify pancreatic exocrine function in normal subjects and in patients with chronic pancreatitis (CP) before and after pancreatic duct drainage procedures (PDDP) with dynamic secretin-enhanced magnetic resonance (MR) cholangiopancreatography (S-MRCP). Pancreatic exocrine secretions [quantified by pancreatic flow output (PFO) and total excreted volume (TEV)] were quantified twice in ten healthy volunteers and before and after treatment in 20 CP patients (18 classified as severe, one as moderate, and one as mild according to the Cambridge classification). PFO and TEV were derived from a linear regression between MR-calculated volumes and time. In all subjects, pancreatic exocrine fluid volume initially increased linearly with time during secretin stimulation. In controls, the mean PFO and TEV were 6.8 ml/min and 97 ml; intra-individual deviations were 0.8 ml/min and 16 ml. In 10/20 patients with impaired exocrine secretions before treatment, a significant increase of PFO and TEV was observed after treatment (P<0.05); 3/20 patients presented post-procedural acute pancreatitis and a reduced PFO. The S-MRCP quantification method used in the present study is reproducible and provides normal values for PFO and TEV in the range of those obtained from previous published intubation studies. The initial results in CP patients have demonstrated non-invasively a significant short-term improvement of PFO and TEV after PDDP. (orig.)

  11. Short-term LNG-markets

    2005-01-01

    The global Liquefied Natural Gas (LNG) industry has experienced substantial growth in the past decades. In the traditional trade patterns of LNG the product has typically been handled within a dedicated chain of plants and vessels fully committed by long term contracts or common ownership, providing risk sharing of large investments in a non-liquid market. Increasing gas prices and substantial cost reductions in all parts of the LNG chain have made LNG projects viable even if only part of the capacity is secured by long-term contracts, opening for more flexible trade of the remainder. Increasing gas demand, especially in power generation, combined with cost reductions in the cost of LNG terminals, open new markets for LNG. For the LNG supplier, the flexibility of shifting volumes between regions represents an additional value. International trade in LNG has been increasing, now accounting for more than one fifth of the world's cross-border gas trade. Despite traditional vertical chain bonds, increased flexibility has contributed in fact to an increasing LNG spot trade, representing 8% of global trade in 2002. The focus of this paper is on the development of global short-term LNG markets, and their role with respect to efficiency and security of supply in European gas markets. Arbitrage opportunities arising from price differences between regional markets (such as North America versus Europe) are important impetuses for flexible short-term trade. However, the short-term LNG trade may suffer from problems related to market access, e.g. limited access to terminals and regulatory issues, as well as rigidities connected to vertical binding within the LNG chain. Important issues related to the role of short-term LNG-trade in the European gas market are: Competition, flexibility in meeting peak demand, security of supply and consequences of differences in pricing policies (oil-linked prices in Europe and spot market prices in North America).

    Neural network memories with storage prescriptions based on Hebb's rule are known to collapse as more words are stored. By requiring that the most recently stored word be remembered precisely, a new simple short-term neutral network memory is obtained and its steady state capacity analyzed and simulated. Comparisons are drawn with Hopfield's method, the delta method of Widrow and Hoff, and the revised marginalist model of Mezard, Nadal, and Toulouse.

    2016-04-18

    Recent research suggests that frequently switching between various forms of media (i.e. 'media multitasking') is associated with diminished attentional abilities, a disconcerting result given the prevalence of media multitasking in today's society. In the present study, we sought to investigate the extent to which the deficits associated with frequent media multitasking can be temporarily ameliorated via a short-term mindfulness intervention previously shown to produce beneficial effects on the attentional abilities of normally functioning individuals. Consistent with previous work, we found: (1) that heavy media multitaskers showed generally poorer attentional abilities than light media multitaskers and (2) that all participants showed benefits from the short-term mindfulness intervention. Furthermore, we found that the benefits of the short-term mindfulness intervention were not equivalently large across participants. Instead, these benefits were disproportionately large in the heavy media multitaskers. While the positive outcomes were short-lived, this opens the possibility of performing long-term interventions with the goal of realizing lasting gains in this population.

    The emphasis on renewable energy and concerns about the environment have led to large-scale wind energy penetration worldwide. However, there are also significant challenges associated with the use of wind energy due to the intermittent and unstable nature of wind. High-quality short-term wind speed forecasting is critical to reliable and secure power system operations. This article begins with an overview of the current status of worldwide wind power developments and future trends. It then reviews some statistical short-term wind speed forecasting models, including traditional time series approaches and more advanced space-time statistical models. It also discusses the evaluation of forecast accuracy, in particular, the need for realistic loss functions. New challenges in wind speed forecasting regarding ramp events and offshore wind farms are also presented. © 2012 The Authors.

    The ODYSSEE database on energy efficiency indicators (www.odyssee-indicators.org) has been set up to enable the monitoring and evaluation of realised energy efficiency improvements and related energy savings. The database covers the 27 EU countries as well as Norway and Croatia and data are available from 1990 on. This work contributes to the growing need for quantitative monitoring and evaluation of the impacts of energy policies and measures, both at the EU and national level, e.g. due to the Energy Services Directive and the proposed Energy Efficiency Directive. Because the underlying data become available only after some time, the savings figures are not always timely available. This is especially true for the ODEX efficiency indices per sector that rely on a number of indicators. Therefore, there is a need for so-called short-term indicators that become available shortly after the year has passed for which data are needed. The short term indicators do not replace the savings indicators but function as a proxy for the savings in the most recent year. This proxy value is faster available, but will be less accurate than the saving indicators themselves. The short term indicators have to be checked regularly with the ODEX indicators in order to see whether they can function still as a proxy.

    To compare the postoperative pain profile, peri-operative details, and short-term patient-reported and objective success rates of single-incision mini-slings (SIMS) versus standard mid-urethral slings (SMUS). In a multicentre prospective randomised trial in six UK centres in the period between October 2009 and October 2010, 137 women were randomised to either adjustable SIMS (Ajust®, C. R. Bard Inc., NJ, USA), performed under local anaesthesia as an opt-out policy (n=69), or SMUS (TVT-O™, Ethicon Inc., Somerville, USA) performed under general anaesthesia (n=68). Randomisation was done through number-allocation software and using telephone randomisation. Postoperative pain profile (primary outcome) was assessed on a ten-point visual analogue scale at fixed time-points. Pre- and post operatively (4-6 months) women completed symptom severity, urgency perception scale (UPS), quality of life and sexual function questionnaires. In addition, women completed a Patient Global Impression of Improvement Questionnaire and underwent a cough stress test at 4-6 months follow up. Sample size calculation was performed and data were analysed using SPSS 18. Descriptive analyses are given and between-group comparisons were performed using chi-square, Fischer exact test and Mann-Whitney test as appropriate. Significance level was set at 5%. Women in the SIMS Ajust® group had a significantly lower postoperative pain profile up to 4 weeks (p=TVT-O™ groups respectively. There was a trend towards higher rates of de novo urgency or worsening of pre-existing urgency in the SIMS Ajust® group (21.7% versus 8.8%) but this did not reach statistical significance (p=0.063). Women in the SIMS Ajust® group had shorter hospital stay (median (IQR) 3.65 (2.49, 4.96)) compared to (4.42 (3.16, 5.56)) the TVT-O™ group 95% CI (-0.026, 1.326), with significantly earlier return to normal activities (p=0.025) and to work (p=0.006).

In separate groups, infarct size, cardiac hemodynamics and protein abundance of caspase 3 was measured at d2 post-MI.This short-term model of CR was associated with cardio-protection, as evidenced by decreased infarct size (18.5±2.4% vs. 26.6±1.7%, N=10/group; P=0.01. mRNA and miR profiles pre-MI (N=5/group identified genes modulated by short-term CR to be associated with circadian clock, oxidative stress, immune function, apoptosis, metabolism, angiogenesis, cytoskeleton and extracellular matrix (ECM. Western blots pre-MI revealed CR-associated increases in phosphorylated Akt and GSK3ß, reduced levels of phosphorylated AMPK and mitochondrial related proteins PGC-1α, cytochrome C and cyclooxygenase (COX IV, with no differences in the levels of phosphorylated eNOS or MAPK (ERK1/2; p38. CR regimen was also associated with reduced protein abundance of cleaved caspase 3 in the infarcted heart and improved cardiac function.

    This paper will giver a general overview of the results from a EU JOULE funded project (`Implementing short-term prediction at utilities`, JOR3-CT95-0008). Reference will be given to specialised papers where applicable. The goal of the project was to implement wind farm power output prediction systems in operational environments at a number of utilities in Europe. Two models were developed, one by Risoe and one by the Technical University of Denmark (DTU). Both prediction models used HIRLAM predictions from the Danish Meteorological Institute (DMI).

    2014-03-01

    Does visual short-term memory (VSTM) depend on depth, as it might be if information was stored in more than one depth layer? Depth is critical in natural viewing and might be expected to affect retention, but whether this is so is currently unknown. Cued partial reports of letter arrays (Sperling, 1960) were measured up to 700 ms after display termination. Adding stereoscopic depth hardly affected VSTM capacity or decay inferred from total errors. The pattern of transposition errors (letters reported from an uncued row) was almost independent of depth and cue delay. We conclude that VSTM is effectively two-dimensional.

In addition, printed versions of the report are available to subscribers in January, April, July and October. The forecast period for this issue of the Outlook extends from July 1998 through December 1999. Values for second quarter of 1998 data, however, are preliminary EIA estimates (for example, some monthly values for petroleum supply and disposition are derived in part from weekly data reported in EIA`s Weekly Petroleum Status Report) or are calculated from model simulations that use the latest exogenous information available (for example, electricity sales and generation are simulated by using actual weather data). The historical energy data, compiled in the July 1998 version of the Short-Term Integrated Forecasting System (STIFS) database, are mostly EIA data regularly published in the Monthly Energy Review, Petroleum Supply Monthly, and other EIA publications. Minor discrepancies between the data in these publications and the historical data in this Outlook are due to independent rounding. 28 figs., 19 tabs.

    The Energy Information Administration (EIA) prepares the Short-Term Energy Outlook (energy supply, demand, and price projections) monthly. The forecast period for this issue of the Outlook extends from January 1999 through December 2000. Data values for the fourth quarter 1998, however, are preliminary EIA estimates (for example, some monthly values for petroleum supply and disposition are derived in part from weekly data reported in EIA`s Weekly Petroleum Status Report) or are calculated from model simulations that use the latest exogenous information available (for example, electricity sales and generation are simulated by using actual weather data). The historical energy data, compiled in the January 1999 version of the Short-Term Integrated Forecasting System (STIFS) database, are mostly EIA data regularly published in the Monthly Energy Review, Petroleum Supply Monthly, and other EIA publications. Minor discrepancies between the data in these publications and the historical data in this Outlook are due to independent rounding. The STIFS model is driven principally by three sets of assumptions or inputs: estimates of key macroeconomic variables, world oil price assumptions, and assumptions about the severity of weather. Macroeconomic estimates are produced by DRI/McGraw-Hill but are adjusted by EIA to reflect EIA assumptions about the world price of crude oil, energy product prices, and other assumptions which may affect the macroeconomic outlook. By varying the assumptions, alternative cases are produced by using the STIFS model. 28 figs., 19 tabs.

  4. Measuring Short-term Energy Security

    Ensuring energy security has been at the centre of the IEA mission since its inception, following the oil crises of the early 1970s. While the security of oil supplies remains important, contemporary energy security policies must address all energy sources and cover a comprehensive range of natural, economic and political risks that affect energy sources, infrastructures and services. In response to this challenge, the IEA is currently developing a Model Of Short-term Energy Security (MOSES) to evaluate the energy security risks and resilience capacities of its member countries. The current version of MOSES covers short-term security of supply for primary energy sources and secondary fuels among IEA countries. It also lays the foundation for analysis of vulnerabilities of electricity and end-use energy sectors. MOSES contains a novel approach to analysing energy security, which can be used to identify energy security priorities, as a starting point for national energy security assessments and to track the evolution of a country's energy security profile. By grouping together countries with similar 'energy security profiles', MOSES depicts the energy security landscape of IEA countries. By extending the MOSES methodology to electricity security and energy services in the future, the IEA aims to develop a comprehensive policy-relevant perspective on global energy security. This Brochure provides and overview of the analysis and results. Readers interested in an in-depth discussion of methodology are referred to the MOSES Working Paper.

    To compare 1-year costs and benefits of dapagliflozin (DAPA), a sodium-glucose cotransporter-2 (SGLT-2) inhibitor, with those of other treatments for type 2 diabetes (T2D), such as glucagon-like peptide-1 receptor agonists (GLP-1RAs), sulfonylureas (SUs), thiazolidinediones (TZDs), and dipeptidyl peptidase-4 inhibitors (DPP-4i), all combined with metformin. A short-term decision-analytic model with a 1-year time horizon was developed from a payer's perspective in the United States setting. Costs and benefits associated with four clinical end-points (glycated hemoglobin [A1C], body weight, systolic blood pressure [SBP], and risk of hypoglycemia) were evaluated in the analysis. The impact of DAPA and other glucose-lowering therapy classes on these clinical end-points was estimated from a network meta-analysis (NMA). Data for costs and quality-adjusted life-years (QALYs) associated with a per-unit change in these clinical end-points were taken from published literature. Drug prices were taken from an annual wholesale price list. All costs were inflation-adjusted to December 2016 costs using the medical care component of the consumer price index. Total costs (both medical and drug costs), total QALYs, and incremental cost-effectiveness ratios (ICERs) were estimated. Sensitivity analyses (SA) were performed to explore uncertainty in the inputs. To assess face validity, results from the short-term model were compared with long-term models published for these drugs. The total annual medical cost for DAPA was less than that for GLP-1RA ($186 less), DPP-4i ($1,142 less), SU ($2,474 less), and TZD ($1,640 less). Treatment with DAPA resulted in an average QALY gain of 0.0107, 0.0587, 0.1137, and 0.0715 per treated patient when compared with GLP-1RA, DPP-4i, SU, and TZD, respectively. ICERs for DAPA vs SU and TZD were $19,005 and $25,835, respectively. DAPA was a cost-saving option when compared with GLP-1RAs and DPP-4is. Among all four clinical end-points, change in weight

    2011-10-01

    Visual short-term memory plays a key role in guiding behavior, and individual differences in visual short-term memory capacity are strongly predictive of higher cognitive abilities. To provide a broader evolutionary context for understanding this memory system, we directly compared the behavior of pigeons and humans on a change detection task. Although pigeons had a lower storage capacity and a higher lapse rate than humans, both species stored multiple items in short-term memory and conformed to the same basic performance model. Thus, despite their very different evolutionary histories and neural architectures, pigeons and humans have functionally similar visual short-term memory systems, suggesting that the functional properties of visual short-term memory are subject to similar selective pressures across these distant species.

    Dupuytren's contracture (DC) is a chronic fibroproliferative disorder of the palmar fascia which leads to flexion contracture in one or more fingers. There is no definitive cure for DC, and treatment aims at relieving symptoms by releasing the contracture using percutaneous or operative techniques. We planned a prospective, randomised, controlled, outcome assessor-blinded, three-armed parallel 1:1:1, multicentre trial comparing the effectiveness and cost of (1) collagenase clostridium histolyticum injection followed by limited fasciectomy in non-responsive cases, (2) percutaneous needle fasciotomy followed by limited fasciectomy in non-responsive cases and (3) primary limited fasciectomy during short-term and long-term follow-up for Tubiana I-III stages DC. We will recruit participants from seven national centres in Finland. Primary outcome is the rate of success in the treatment arm at 5 years after recruitment. Success is a composite outcome comprising (1) at least 50% contracture release from the date of recruitment and (2) participants in a patient-accepted symptom state (PASS). Secondary outcomes are (1) angle of contracture, (2) quick disabilities of the arm, a shoulder and hand outcome measure (QuickDASH), (3) perceived hand function, (4) EQ-5D-3L, (5) rate of major adverse events, (6) patient's trust of the treatment, (7) global rating, (8) rate of PASS, (9) rate of minimal clinically important improvement, (10) expenses, (11) progression of disease, (12) progression-free survival, (13) favoured treatment modality, (14) patients achieving full contracture release and >50% improvement and (15) patient satisfaction with the treatment effect. Predictive factors for achieving the PASS will also be analysed. The protocol was approved by the Tampere University Hospital Institutional Review Board and Finnish Medicine Agency. The study will be performed according to the principles of good clinical practice. The results of the trial will be disseminated as

    A new methodological approach to the forecasting of short-term trends in internal migration in the United States is introduced. "Panel-data (or longitudinal-data) models are used to represent the relationship between destination-specific out-migration and several explanatory variables. The introduction of this methodology into the migration literature is possible because of some new and improved databases developed by the U.S. Bureau of the Census.... Data from the Bureau of Economic Analysis are used to investigate the incorporation of exogenous factors as variables in the model." The exogenous factors considered include employment and unemployment, income, population size of state, and distance between states. The author concludes that "when one...includes additional parameters that are estimable in longitudinal-data models, it turns out that there is little additional information in the exogenous factors that is useful for forecasting." excerpt

  10. Economics of solar energy: Short term costing

    Science.gov (United States)

    Klee, H.

    The solar economics based on life cycle costs are refuted as both imaginary and irrelevant. It is argued that predicting rates of inflation and fuel escalation, expected life, maintenance costs, and legislation over the next ten to twenty years is pure guesswork. Furthermore, given the high mobility level of the U.S. population, the average consumer is skeptical of long run arguments which will pay returns only to the next owners. In the short term cost analysis, the house is sold prior to the end of the expected life of the system. The cash flow of the seller and buyer are considered. All the relevant factors, including the federal tax credit and the added value of the house because of the solar system are included.

To contrast mechanisms of target selection, distracter filtering, and access to VSTM, we combined behavioral testing, computational modeling and functional magnetic resonance......, thereby displaying a significant interaction between the two factors. The interaction between target and distracter set size in IPS could not be accounted for by a simple explanation in terms of number of items accessing VSTM. Instead, it led us to a model where items accessing VSTM receive differential...

    2016-01-01

    We reveal the universality of short-term anisotropic inflation. As a demonstration, we study inflation with an exponential type gauge kinetic function which is ubiquitous in models obtained by dimensional reduction from higher dimensional fundamental theory. It turns out that an anisotropic inflation universally takes place in the later stage of conventional inflation. Remarkably, we find that primordial gravitational waves with a peak amplitude around 10 −26 ∼10 −27 are copiously produced in high-frequency bands 10 MHz∼100 MHz. If we could detect such gravitational waves in future, we would be able to probe higher dimensional fundamental theory.

    2007-01-01

    Energy forecasting requirements for Slovenia's natural gas market were investigated along with the cycles of natural gas consumption. This paper presented a short-term natural gas forecasting approach where the daily, weekly and yearly gas consumption were analyzed and the information obtained was incorporated into the forecasting model for hourly forecasting for the next day. The natural gas market depends on forecasting in order to optimize the leasing of storage capacities. As such, natural gas distribution companies have an economic incentive to accurately forecast their future gas consumption. The authors proposed a forecasting model with the following properties: two submodels for the winter and summer seasons; input variables including past consumption data, weather data, weather forecasts and basic cycle indexes; and, a hierarchical forecasting structure in which a daily model was used as the basis, with the hourly forecast obtained by modeling the relative daily profile. This proposed method was illustrated by a forecasting example for Slovenia's natural gas market. 11 refs., 11 figs

  19. A fuzzy inference model for short-term load forecasting

    International Nuclear Information System (INIS)

    Mamlook, Rustum; Badran, Omar; Abdulhadi, Emad

    2009-01-01

    This paper is concerned with the short-term load forecasting (STLF) in power system operations. It provides load prediction for generation scheduling and unit commitment decisions, and therefore precise load forecasting plays an important role in reducing the generation cost and the spinning reserve capacity. Short-term electricity demand forecasting (i.e., the prediction of hourly loads (demand)) is one of the most important tools by which an electric utility/company plans, dispatches the loading of generating units in order to meet system demand. The accuracy of the dispatching system, which is derived from the accuracy of the forecasting algorithm used, will determine the economics of the operation of the power system. The inaccuracy or large error in the forecast simply means that load matching is not optimized and consequently the generation and transmission systems are not being operated in an efficient manner. In the present study, a proposed methodology has been introduced to decrease the forecasted error and the processing time by using fuzzy logic controller on an hourly base. Therefore, it predicts the effect of different conditional parameters (i.e., weather, time, historical data, and random disturbances) on load forecasting in terms of fuzzy sets during the generation process. These parameters are chosen with respect to their priority and importance. The forecasted values obtained by fuzzy method were compared with the conventionally forecasted ones. The results showed that the STLF of the fuzzy implementation have more accuracy and better outcomes

    2014-08-15

    Learning and memory represent perhaps the most complex behavioral phenomena. Although their underlying mechanisms have been extensively analyzed, only a fraction of the potential molecular components have been identified. The zebrafish has been proposed as a screening tool with which mechanisms of complex brain functions may be systematically uncovered. However, as a relative newcomer in behavioral neuroscience, the zebrafish has not been well characterized for its cognitive and mnemonic features, thus learning and/or memory screens with adults have not been feasible. Here we study short-term memory of adult zebrafish. We show animated images of conspecifics (the stimulus) to the experimental subject during 1 min intervals on ten occasions separated by different (2, 4, 8 or 16 min long) inter-stimulus intervals (ISI), a between subject experimental design. We quantify the distance of the subject from the image presentation screen during each stimulus presentation interval, during each of the 1-min post-stimulus intervals immediately following the stimulus presentations and during each of the 1-min intervals furthest away from the last stimulus presentation interval and just before the next interval (pre-stimulus interval), respectively. Our results demonstrate significant retention of short-term memory even in the longest ISI group but suggest no acquisition of reference memory. Because in the employed paradigm both stimulus presentation and behavioral response quantification is computer automated, we argue that high-throughput screening for drugs or mutations that alter short-term memory performance of adult zebrafish is now becoming feasible.

  1. Short-term risk of falling after cochlear implantation.

    2014-01-01

    Cochlear implantation is a highly effective intervention for hearing loss, but insertion of an implant into the cochlea is often accompanied by loss of residual hearing function. Sometimes, postoperative testing also shows loss of function in the semicircular canals or otolith organs. The effect of this loss on equilibrium, particularly in the short term following surgery, and the risk of falling due to this loss is unknown. We prospectively measured balance in 16 consecutive adult cochlear implant patients before and 2 weeks after surgery. Subjects stood on a foam pad with eyes closed, feet together and arms at the side. The length of time over which this posture could be maintained was recorded up to a maximum value of 30 s indicating normal performance. Ten of 16 subjects reached a maximal time on preoperative testing. Nine of 16 subjects lost balance function after surgery. Four of the 10 subjects with normal preoperative balance function lost function. Subjects older than the age of 60 were more likely to lose balance function than younger subjects. We used previously published values relating balance performance on foam to risk of falling to calculate the fall risk among our subjects. The relative risk of falling increased after surgery by more than threefold in some patients. Imbalance after cochlear implantation may be much more common, particularly in the short term, than previously appreciated. This imbalance is accompanied by an increased risk of falling in many patients. Careful preoperative counseling before implantation and postoperative therapeutic intervention to improve comfort and reduce the chance of falling may be warranted, particularly in patients at a risk for injuries from falls (level of evidence: 2b). © 2014 S.

    1979-01-01

    The genetic effects induced by α irradiation were examined using short term assays in Procaryotes and Eucaryotes. Irradiation was produced by 239 Pu dissolved as a DTPA equimolar complex in the culture medium. Induced mutagenesis was not observed with Ames' test or when test for ouabain resistance in CHO cells was used: GTG resistance and chromosome aberrations in Eucaryote cells were increased at dose rate exposure down to 5 R.day -1 . Until an optimal delivered dose, these two biological effects have shown a linear increase as a function of the dose. In our experimental conditions α irradiation has appeared to be much more lethal than mutagenic. Using lower dose rate, corresponding to 1 and 3 R a day we could also demonstrate a linear increase with dose of the induced TG resistant cells. Efficiency per unit dose was 3 to 5 times superior to what was observed at 5 R.day -1 . This phenomenon could correspond to an induced cell sensitivity, and clearly pointed out that for chronic and low delivered doses, informations deduced from flash or short term α exposure are not valuable

    To report an unusual case of hydroxychloroquine toxicity after short-term therapy. Observational case report. A 56-year-old woman presented to the Ophthalmology Clinic at Walter Reed Army Medical Center (WRAMC) with a 6-month history of gradually decreasing vision in both eyes. The patient had been taking hydroxychloroquine for the preceding 48 months for the treatment of rheumatoid arthritis. Examination of the posterior segment revealed bilateral "bull's eye" macular lesions. Fundus autofluorescence revealed hyperfluorescence of well-defined bull's eye lesions in both eyes. Optical coherence tomography revealed corresponding parafoveal atrophy with a loss of the retinal inner segment/outer segment junction. Humphrey visual field 10-2 white showed significant central and paracentral defects with a generalized depression. The patient was on a standard dose of 400 mg daily, which was above her ideal dose. The patient had no history of kidney or liver dysfunction. There were no known risk factors but there were several possible confounding factors. The patient was started on high-dose nabumetone, a nonsteroidal antiinflammatory drug, at the same time she was started on hydroxychloroquine. She also reported taking occasional ibuprofen. Retinal toxicity from chloroquine has been recognized for decades with later reports showing retinopathy from long-term hydroxychloroquine (Plaquenil) use for the treatment of antiinflammatory diseases. Hydroxychloroquine is now widely used and retinal toxicity is relatively uncommon. However, it can cause serious vision loss and is usually irreversible. The risk of hydroxychloroquine toxicity rises to nearly 1% with a total cumulative dose of 1,000 g, which is ∼5 years to 7 years of normal use. Toxicity is rare under this dose. For this reason, the American Academy of Ophthalmology has revised its recommendations such that annual screenings begin 5 years after therapy with hydroxychloroquine has begun unless there are known risk

We investigated whether irrelevant visual information has an analogous effect on visual short-term memory, using a dynamic visual noise (DVN) technique known to disrupt visual imagery (Quinn & McConnell, 1996a). Experiment 1 replicated the effect of DVN on pegword imagery. Experiments 2 and 3 showed no effect of ...

    In contrast to chronic/long-term stress that suppresses/dysregulates immune function, an acute/short-term fight-or-flight stress response experienced during immune activation can enhance innate and adaptive immunity. Moderate ultraviolet-B (UV) exposure provides a non-invasive system for studying the naturalistic emergence, progression and regression of squamous cell carcinoma (SCC). Because SCC is an immunoresponsive cancer, we hypothesized that short-term stress experienced before UV exposu...
