RESUMEN
Many sports employ caloric restriction (CR) to reduce athletes' body mass. During these phases, resistance training (RT) volume is often reduced to accommodate recovery demands. Since RT volume is a well-known anabolic stimulus, this review investigates whether a higher training volume helps to spare lean mass during CR. A total of 15 studies met inclusion criteria. The extracted data allowed calculation of total tonnage lifted (repetitions × sets × intensity load) or weekly sets per muscle group for only 4 of the 15 studies, with RT volume being highly dependent on the examined muscle group as well as weekly training frequency per muscle group. Studies involving high RT volume programs (≥ 10 weekly sets per muscle group) revealed low-to-no (mostly female) lean mass loss. Additionally, studies increasing RT volume during CR over time appeared to demonstrate no-to-low lean mass loss when compared to studies reducing RT volume. Since data regarding RT variables applied were incomplete in most of the included studies, evidence is insufficient to conclude that a higher RT volume is better suited to spare lean mass during CR, although data seem to favor higher volumes in female athletes during CR. Moreover, the data appear to suggest that increasing RT volume during CR over time might be more effective in ameliorating CR-induced atrophy in both male and female resistance-trained athletes when compared to studies reducing RT volume. The effects of CR on lean mass sparing seem to be mediated by training experience, pre-diet volume, and energy deficit, with, on average, women tending to spare more lean mass than men. Potential explanatory mechanisms for enhanced lean mass sparing include a preserved endocrine milieu as well as heightened anabolic signaling.

BACKGROUND: Cystic abdominal masses are a common main or incidental finding in daily radiological practice; however, differentiation is not always trivial. OBJECTIVES: In children, cystic abdominal masses represent a special feature compared to adults, since the spectrum of congenital lesions must be taken into consideration. The article gives a structured overview of the most common entities. MATERIALS AND METHODS: The standard methods in abdominal imaging in pediatric radiology are ultrasound and MRI. Based on a literature review, the most important differential diagnoses with their characteristics in ultrasound and MRI were compiled. RESULTS AND DISCUSSION: With anatomical classification, presence or absence of solid components as well as the contrast agent behavior in the MRI, the cystic masses can be well differentiated and classified into three groups: congenital and acquired cysts as well as neoplasms.

Hereditary neuropathies are a group of diseases of which the most prevalent is Charcot Marie Tooth disease (CMT). From the clinical point of view pes cavus is a typical yet not specific sign for CMT. Motor signs like bilateral foot drop are dominant over sensory signs. Mutations in some 80 genes can lead to CMT. Whereas clinical sign can hardly differentiate between these genotypes, there is a clear differentiation by classical neurography: median nerve conduction velocity of less or more than 38âmâ/âs differentiates between CMT type 1 and CMT type 2. The two most common forms are CMT1A induced by duplication of the PMP22 gene and hereditary neuropathy with liability to pressure palsy (HNPP) induced by deletion of the PMP22 gene.

High-harmonic generation (HHG) is widely used for up-conversion of amplified (near) infrared ultrafast laser pulses to short wavelengths. We demonstrate that Ramsey-comb spectroscopy, based on two such pulses derived from a frequency-comb laser, enables us to observe phase effects in this process with a few mrad precision. As a result, we could perform the most accurate spectroscopic measurement based on light from HHG, illustrated with a determination of the 5p^{6}â5p^{5}8s^{2}[3/2]_{1} transition at 110 nm in ^{132}Xe. We improve its relative accuracy 10^{4} times to a value of 2.3×10^{-10}. This is 3.6 times better than shown before involving HHG, and promising to enable 1S-2S spectroscopy of He^{+} for fundamental tests.
RESUMEN
Development and testing of reliable tools for simulating rice production in salt-affected areas are presented in this paper. New functions were implemented in existing crop models ORYZA v3 and the cropping systems modelling framework APSIM. Field experiments covering two years, two different sites, and three varieties were used to validate both improved models. We used the salt balance module in the systems model APSIM to simulate the observed daily soil salinity with acceptable accuracy (RMSEn <35%), whereas ORYZA v3 used measured soil salinity at a given interval of days as a model input. Both models presented similarly good accuracy in simulating aboveground biomass, leaf area index, and grain yield for IR64 over a gradient of salinity conditions. The model index of agreement ranged from 0.86 to 0.99. Variability of yield under stressed and non-stressed conditions was simulated with a RMSE, of 191â¯kgâ¯ha-1 and 222â¯kgâ¯ha-1 , respectively, for ORYZA v3 and APSIM-Oryza, corresponding to an RMSEn of 14.8% and 17.3%. These values are within the bounds of experimental error, therefore indicating acceptable model performance. The model test simulating genotypic variability of rice crop responses resulted in similar levels of acceptable model performance with RMSEn ranging from 11.3 to 39.9% for observed total above ground biomass for IR64 and panicle biomass for IR29, respectively. With the improved models, more reliable tools are now available for use in risk assessment and evaluation of suitable management options for rice production in salt-affected areas. The approach presented may also be applied in improving other non-rice crop models to integrate a response to soil salinity - particularly in process-based models which capture stage-related stress tolerance variability and resource use efficiency.
RESUMEN
BACKGROUND AND PURPOSE: Based on the data of several trials the Totaled Health Risks in Vascular Events (THRIVE) score has been shown to predict outcome after either intravenous thrombolysis (IVT) or endovascular therapy (ET) in acute stroke patients. It is unknown whether the THRIVE score can also predict outcome in everyday clinical practice. Using our prospectively obtained stroke database the utility of the THRIVE score to predict clinical and radiological outcome in everyday clinical practice was analysed. METHODS: The relationships between THRIVE and good outcome (modified Rankin Scale ≤ 2 at discharge), poor outcome (modified Rankin Scale 5-6), in-hospital death, symptomatic intracranial haemorrhage (SICH) as well as infarct size were examined in patients with distal intracranial carotid artery, M1 and M2 occlusions after either IVT or ET. RESULTS: From January 2008 to October 2016 a total of 546 patients were treated with IVT and 492 patients received ET with stent retrievers (with or without IVT). In both treatment groups the THRIVE score predicted clinical outcome (Mantel-Haenszel chi-squared tests for trend P < 0.001 for good outcome, P < 0.001 for poor outcome and P < 0.001 for in-hospital death). In the ET group the THRIVE score remained an independent predictor of outcome after controlling for recanalization. The THRIVE score was associated with the infarct size after IVT or ET, whereas it did not predict SICH rates in either treatment group. CONCLUSIONS: In everyday clinical practice the THRIVE score strongly predicts clinical outcome and the extent of ischaemia after ET or IVT in patients with anterior circulation large vessel occlusions.

BACKGROUND AND AIMS: There are guidelines for the medical management of cirrhosis and associated quality indicators (QIs), but QIs focusing on standards for palliative aspects of care are needed. METHODS: We convened a 9-member, multidisciplinary expert panel and used RAND/UCLA modified Delphi methods to develop palliative care quality indicators for patients with cirrhosis. Experts were provided with a report based on a systematic review of the literature that contained evidence concerning the proposed candidate QIs. Panelists rated QIs prior to a planned meeting using a standard 9-point RAND appropriateness scale. These ratings guided discussion during a day-long phone conference meeting, and final ratings were then provided by panel members. Final QI scores were computed and QIs with a final median score of greater than or equal to 7, and no disagreement was included in the final set. RESULTS: Among 28 candidate QIs, the panel rated 19 as valid measures of quality care. These 19 quality indicators cover care related to information and care planning (13) and supportive care (6). CONCLUSIONS: These QIs are evidence-based process measures of care that may be useful to improve the quality of palliative care. Research is needed to better understand the quality of palliative care provided to patients with cirrhosis.

BACKGROUND AND PURPOSE: Theoretical considerations and the results of animal studies indicate that manual lymphatic drainage (MLD) might have an impact on intracranial pressure (ICP). There is a lack of clinically qualitative investigations on patients with severe cerebral diseases. METHODS: Between April 2013 and January 2015 a prospective observational study was performed on patients who were undergoing intracranial pressure measurement and treatment with MLD. ICP, cerebral perfusion pressure, mean arterial pressure (MAP), heart rate and oxygen saturation were recorded continuously 15 min before the procedure, during MLD (22 min) and for 15 min after the procedure. For analysis the data treatment units were divided into two groups: patients with a mean baseline ICP <15 mmHg (group 1) and patients with a mean ICP ≥15 mmHg before MLD (group 2). RESULTS: A total of 133 treatment units (61 patients) were analysed (group 1 n = 99; group 2 n = 34). The mean baseline ICP was 10.4 mmHg overall, and 8.3 mmHg and 18.6 mmHg respectively in group 1 and group 2; ICP significantly decreased during therapy with MLD and this persisted during the follow-up period in group 2. MAP did not show any significant differences between the different periods. CONCLUSIONS: Our data showed a significant reduction of ICP during therapy with craniocervical MLD in patients with severe cerebral diseases.

BACKGROUND AND PURPOSE: Endovascular therapy (ET) is superior to intravenous thrombolysis (IVT) in selected patients with anterior circulation large vessel occlusions. However, it is unclear if this positive effect also applies to patients with extensive early ischaemic changes. The aim of this study was to analyze the impact of the Alberta Stroke Program Early Computed Tomography Score (ASPECTS) on the CT angiography source images (SI) on outcome after ET or IVT. METHODS: Using our prospectively obtained stroke database and the admission SI-ASPECTS divided into three groups (0-5, 6-7 and 8-10), primarily the rates of good outcome [modified Rankin Scale (mRS) ≤2 at discharge] after either ET (n = 255) or IVT (n = 479) were compared. RESULTS: A favorable SI-ASPECTS (8-10) was present in 501 patients, 132 patients had a moderately favorable SI-ASPECTS (6-7) and 101 patients had an unfavorable SI-ASPECTS (0-5). Irrespective of the treatment modality, no patient with an unfavorable SI-ASPECTS had a good outcome and 38% died during hospital stay. Whilst significantly more patients with a favorable SI-ASPECTS had a good outcome after ET than after IVT (51% vs. 35%, P < 0.01), there was only a non-significant trend towards a good outcome after ET than after IVT in patients with a moderately favorable ASPECTS (25% vs. 14%, P = 0.1). CONCLUSION: Patients with extensive early ischaemic changes on CT scans (SI- ASPECTS ≤5) might not profit from ET. The impact of ET on outcome in patients with moderately favorable SI-ASPECTS should be addressed in further trials.

BACKGROUND: The impact of levosimendan treatment on clinical outcome in patients undergoing extracorporeal membrane oxygenation (ECMO) support after cardiovascular surgery is unknown. We hypothesized that the beneficial effects of levosimendan might improve survival when adequate end-organ perfusion is ensured by concomitant ECMO therapy. We therefore studied the impact of levosimendan treatment on survival and failure of ECMO weaning in patients after cardiovascular surgery. METHODS: We enrolled a total of 240 patients undergoing veno-arterial ECMO therapy after cardiovascular surgery at a university-affiliated tertiary care centre into our observational single-centre registry. RESULTS: During a median follow-up period of 37 months (interquartile range 19-67 months), 65% of patients died. Seventy-five per cent of patients received levosimendan treatment within the first 24 h after initiation of ECMO therapy. Cox regression analysis showed an association between levosimendan treatment and successful ECMO weaning [adjusted hazard ratio (HR) 0.41; 95% confience interval (CI) 0.22-0.80; P=0.008], 30 day mortality (adjusted HR 0.52; 95% CI 0.30-0.89; P=0.016), and long-term mortality (adjusted HR 0.64; 95% CI 0.42-0.98; P=0.04). CONCLUSIONS: These data suggest an association between levosimendan treatment and improved short- and long-term survival in patients undergoing ECMO support after cardiovascular surgery.

BACKGROUND: Intrahospital transport is associated with a high rate of complications. Investigations of this problem using neuromonitoring remain scarce. METHODS: This is a monocentric, prospective observational study. Patients with severe brain diseases and intracranial pressure (ICP) monitoring were included. Continuous monitoring of ICP, cerebral perfusion pressure (CPP), oxygen saturation (SpO2), heart rate, and mean arterial pressure was measured during seven different periods of intrahospital transport (baseline for 30 min, I = preparation, II = transport I, III = CT scan, IV = transport II, V = postprocessing, and follow-up for another 30 min). All complications were documented. RESULTS: Between July 2013 and December 2013, a total number of 56 intrahospital transports of 43 patients were performed from ICU to CT. Data recording was incomplete in six cases. Fifty transports have been taken into account for statistical analysis. Forty-two percent were emergency transports. Mean duration of the procedure was 17' (preparation), 6' (transport I), 9' (CT scan), 6' (transport II), and 15' (postprocessing), respectively. Mean ICP at baseline was 8.53 mmHg. Comparing all periods of intrahospital transport and the follow-up period to the baseline showed a significant increase of ICP only during CT scan (15.83 mmHg, p < 0.01), not during the transport to and from the radiology department. An overall complication rate of 36 % (n = 18) was observed. In 26 % (n = 13), additional ICP therapy was necessary due to an elevation of ICP above 20 mmHg. CONCLUSION: There is a considerable rate of complications during intrahospital transport of critically ill patients with severe brain diseases, with a significant increase of ICP during transport and CT scan. In one-fifth of all patients, additional therapy was necessary. From our point of view, transport of critically ill patients should only be performed by trained staff and under monitoring of ICP and CPP.

The focus of this review article is on child abuse and the radiographic pattern of Xray findings. The radiologist should be able to recognize typical injuries resulting from child abuse. In some cases the findings are highly specific for abuse and these include metaphyseal corner fractures of the long bones in children aged up to 24 months. In other cases the fractures are not specific but highly indicative of child abuse: rib fractures, for example can be associated with child abuse in more than 50 % of the cases; however, maltreatment is difficult to diagnose without taking the entire pattern of skeletal findings into consideration so that a radiological screening of the entire skeleton is often necessary. The concept of sentinel injuries might be helpful for deciding in which cases a complete skeletal screening should be performed. In the age group up to 24 months old a complete skeletal status (with some exceptions) is recommended if one of the three sentinel injuries of rib fractures, intracranial bleeding and abdominal trauma is present.

BACKGROUND: Worldwide there are differences in the procedure of determining brain death. An irreversible loss of all brain functions, including cerebrum, cerebellum and brainstem is mandatory for the diagnosis of brain death in Germany. On the basis of a case report some important aspects of the new recommendations of the German guidelines are discussed. CASE REPORT: We present the case of a 41-year old patient who was admitted to our clinic due to acute subarachnoid hemorrhage (SAH). Angiography revealed an aneurysm of the posterior inferior cerebellar artery. The patient was comatose without any brainstem reflexes and showed apnoea. However, on day 3, EEG showed alpha activity as a sign of residual cortical function. We diagnosed an isolated brainstem death. The next day EEG was isoelectric and brain death was confirmed. DISCUSSION: The diagnosis of isolated brainstem death does not allow a confirmation of death in Germany. Our case presents a primary infratentorial brain damage mandating additional confirmatory tests.

BACKGROUND AND PURPOSE: Some authors have suggested a rise of intracranial pressure (ICP) during apnoea testing and the possibility of harm to patients. Data, however, have yet to be obtained. METHODS: Between October 2012 and May 2014 an observational study was performed on patients who received ICP measurements and who underwent brain death diagnosis. ICP, cerebral perfusion pressure (CPP), mean arterial blood pressure (MAP) and heart rate were recorded continuously from 15 min before the start of brain death diagnosis (baseline), during clinical examination including apnoea testing, until 15 min after this procedure. RESULTS: A total of 16 clinical examinations for brain death including apnoea testing were performed on 13 patients. All patients had primary brain lesions. Mean ICP and mean CPP during the examination were 95 ± 27.7 mmHg and 13.5 ± 20.7 mmHg, respectively. ICP and MAP showed a strong and statistically significant correlation, with Pearson's correlation coefficients of more than +0.6 or less than -0.6 in 13 of the 15 examinations. CONCLUSION: Mean ICP even before brain death determination is increased excessively. Changes of ICP during apnoea show a clear correlation to the changes of MAP. Furthermore, CPP during the condition of brain death may not equal zero but may be positive thereby indicating some minor net influx of blood into the brain in some patients.

OBJECTIVE: To examine the association between maternal use of selective serotonin reuptake inhibitors (SSRI) in pregnancy and language competence in their children at age three taking into account maternal symptoms of anxiety and depression. DESIGN: Population-based prospective pregnancy cohort study. SETTING: The Norwegian Mother and Child Cohort Study; recruited pregnant women from 1999 through 2008. POPULATION: 45,266 women with 51,748 singleton pregnancies. METHODS: The association between short- or long-term use of SSRI during pregnancy and language competence in the child was investigated using multinomial logistic regression with three outcome categories: long, complicated sentences, fairly complete sentences and language delay. MAIN OUTCOME MEASURES: Children's language competence at age three measured by maternal report on a validated language grammar scale. RESULTS: Women reported use of SSRI in 386 (0.7%) pregnancies. Of these, 161 (42%) reported long-term use. Compared with children whose mothers took no SSRI, using the best language category as the reference, adjusted relative risk ratios (RRR) of having fairly complete sentences were 1.21 (95% CI 0.85-1.72) and 2.28 (1.54-3.38) for short- and long-term SSRI use, respectively. The adjusted RRRs of language delay were 0.86 (0.42-1.76) and 2.30 (1.21-4.37). Symptoms of anxiety and depression in pregnancy were independently related to language delay, adjusted RRR 1.25 (1.03-1.50) and 1.83 (1.40-2.40) for short- and long-term symptoms, respectively. CONCLUSIONS: Prolonged use of SSRI during pregnancy was associated with lower language competence in children by age three independently of depression. Having symptoms of depression throughout pregnancy had an independent effect.

In operando X-ray absorption spectroscopy data using the Δµ X-ray Absorption Near Edge Spectroscopy (XANES) analysis procedure is used to follow the ORR intermediate adsorbate coverage on a working catalyst in a PEMFC during initial activation and break-in. The adsorbate coverage and log i (Tafel) curves reveal a strong correlation, i.e., an increase in adsorbate intermediate coverage poisons Pt sites thereby decreasing the current. A decrease in Pt-O bond strength commensurate with decrease in potential causes a sequence of different dominant adsorbate volcano curves to exist, namely first O, then OH, and then OOH exactly as predicted by the different ORR kinetics mechanisms. During break-in, the incipient O coverage coming from exposure to air during storage and MEA preparation is rather quickly removed, compared to the slower and more subtle nanoparticle morphological changes, such as the rounding of the Pt nanoparticle edges/corners and smoothing of the planar surfaces, driven by the nanoparticle's tendency to lower its surface energy. These morphological changes increase the Pt-Pt average coordination number, decrease the average Pt-O bond strength, and thereby decrease the coverage of ORR intermediates, allowing increase in the current.
RESUMEN
The One Health approach encompasses multiple themes and can be understood from many different perspectives. This paper expresses the viewpoint of those in charge of responding to public health events of international concern and, in particular, to outbreaks of zoonotic disease. Several international organisations are involved in responding to such outbreaks, including the United Nations (UN) and its technical agencies; principally, the Food and Agriculture Organization of the UN (FAO) and the World Health Organization (WHO); UN funds and programmes, such as the United Nations Development Programme, the World Food Programme, the United Nations Environment Programme, the United Nations Children's Fund; the UN-linked multilateral banking system (the World Bank and regional development banks); and partner organisations, such as the World Organisation for Animal Health (OIE). All of these organisations have benefited from the experiences gained during zoonotic disease outbreaks over the last decade, developing common approaches and mechanisms to foster good governance, promote policies that cut across different sectors, target investment more effectively and strengthen global and national capacities for dealing with emerging crises. Coordination among the various UN agencies and creating partnerships with related organisations have helped to improve disease surveillance in all countries, enabling more efficient detection of disease outbreaks and a faster response, greater transparency and stakeholder engagement and improved public health. The need to build more robust national public human and animal health systems, which are based on good governance and comply with the International Health Regulations (2005) and the international standards set by the OIE, prompted FAO, WHO and the OIE to join forces with the World Bank, to provide practical tools to help countries manage their zoonotic disease risks and develop adequate resources to prevent and control disease outbreaks, particularly at the animal source. All these efforts contribute to the One Health agenda.

BACKGROUND: Hormone and human epidermal growth factor receptor 2 (HER2) receptors are the most important breast cancer biomarkers, and additional objective and quantitative test methods such as messenger RNA (mRNA)-based quantitative analysis are urgently needed. In this study, we investigated the clinical validity of RT-PCR-based evaluation of estrogen receptor (ESR1) and HER2 mRNA expression. PATIENTS AND METHODS: A total of 1050 core biopsies from two retrospective (GeparTrio, GeparQuattro) and one prospective (PREDICT) neoadjuvant studies were evaluated by quantitative RT-PCR for ESR1 and HER2. RESULTS: ESR1 mRNA was significantly predictive for reduced response to neoadjuvant chemotherapy in univariate and multivariate analysis in all three cohorts. The complete pathologically documented response (pathological complete response, pCR) rate for ESR1+/HER2- tumors was 7.3%, 8.0% and 8.6%; for ESR1-/HER2- tumors it was 34.4%, 33.7% and 37.3% in GeparTrio, GeparQuattro and PREDICT, respectively (P < 0.001 in each cohort). In the Kaplan-Meier analysis in GeparTrio patients with ESR1+/HER2- tumors had the best prognosis, compared with ESR1-/HER2- and ESR1-/HER2+ tumors [disease-free survival (DFS): P < 0.0005, overall survival (OS): P < 0.0005]. CONCLUSIONS: Our results suggest that mRNA levels of ESR1 and HER2 predict response to neoadjuvant chemotherapy and are significantly associated with long-term outcome. As an additional option to standard immunohistochemistry and gene-array-based analysis, quantitative RT-PCR analysis might be useful for determination of the receptor status in breast cancer.

Our objectives were to determine whether migrant women in Western industrialized countries have higher odds of inadequate prenatal care (PNC) compared to receiving-country women and to summarize factors that are associated with inadequate PNC among migrant women in these countries. We conducted searches of electronic databases (MEDLINE, EMBASE, and PsycINFO), reference lists, known experts, and an existing database of the Reproductive Outcomes And Migration international research collaboration for articles published between January, 1995 and April, 2010. Title and abstract review and quality appraisal were conducted independently by 2 reviewers using established criteria, with consensus achieved through discussion. In this systematic review of 29 studies, the majority of studies demonstrated that migrant women were more likely to receive inadequate PNC than receiving-country women, with most reporting moderate to large effect sizes. Rates of inadequate PNC among migrant women varied widely by country of birth. Only three studies explored predictors of inadequate PNC among migrant women. These studies found that inadequate PNC among migrant women was associated with being less than 20 years of age, multiparous, single, having poor or fair language proficiency, education less than 5 years, an unplanned pregnancy, and not having health insurance. We concluded that migrant women as a whole were more likely to have inadequate PNC and the magnitude of this risk differed by country of origin. Few studies addressed predictors of PNC utilization in migrant women and this limits our ability to provide effective PNC in this population.

Olanzapine is a second-generation antipsychotic, which is also used as a mood stabilizer. We report a case of a 33-year-old psychiatric patient, with bipolar affective disorder, who developed anaphylaxis as a late reaction to olanzapine. This case report shows the possibility, although rare, of a severe late anaphylactic reaction to olanzapine.
