RESUMO
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.

AIM: In 2015, the revised International Pediatric Non-Hodgkin Lymphoma Staging System was published. It mentions [18F]-FDG-PET/MRI as the latest method to perform whole-body imaging. However, supporting data are pending. Our aim was to investigate the performance of whole-body [18F]-FDG-PET/MRI in pediatric non-Hodgkin lymphoma patients by using a limited number of MRI sequences. MATERIALS AND METHODS: Ten pediatric patients with histologically proven non-Hodgkin lymphoma underwent whole-body [18F]-FDG-PET/MRI at staging. The retrospective analysis included three steps: First, [18F]-FDG-PET and MR scans were evaluated separately by a nuclear medicine physician and a pediatric radiologist. Nineteen nodal and two extranodal regions as well as six organs were checked for involvement. Second, discrepant findings were reviewed together in order to reach consensus. Third, [18F]-FDG-PET/MRI findings were correlated with the results of other clinical investigations. RESULTS: Of the 190 lymph node regions evaluated, four were rated controversial. Consensus was reached by considering metabolic, functional and morphologic information combined. Concordantly, [18F]-FDG-PET and MRI detected Waldeyer's ring involvement in two patients whose Waldeyer's ring was negative on clinical assessment. In four patients MRI showed pleural effusion. However, in only two of them an increased glucose metabolism as a reliable sign of pleural involvement was detectable. In six patients [18F]-FDG-PET and MRI detected skeletal lesions although bone marrow biopsy was positive in only one of them. CONCLUSION: Despite the small number of cases evaluated, whole-body [18F]-FDG-PET turned out to be a valuable tool for staging of pediatric non-Hodgkin lymphoma.
RESUMO
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.

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.

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.
RESUMO
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.
RESUMO
OBJECTIVES: Viruses are recognized as important agents of gastroenteritis outbreaks in institutions caring for dependent people. We aimed to define norovirus (NoV) and rotavirus (RV) immunochromatographic tests (ICT) and reverse transcription-polymerase chain reaction (RT-PCR) used in gastroenteritis investigations. METHODS: Fourteen sites were monitored from 2010 to 2015, with 360 laboratory investigations. Twenty-two outbreaks and 44 sporadic case patients were investigated with ICTs (114 NoVs and 80 RVs) and RT-PCRs (114 NoVs and 52 RVs). RESULTS: ICTs were useful during outbreaks (identification of NoVs and RVs in respectively 76.5% and 75.0% of episodes) despite the NoV sensitivity limit (55.1%) and the four RV false positive results observed for 10 samples. Given the NoV ICT performance and the observed variations of the NoV and RV prevalence (between 20.0% and 5.0%), ICTs are not appropriate to identify sporadic gastroenteritis case patients. Positive predictive values <60.0% were observed when the prevalence of RV and NoV was low (<5.0%). NoV and RV RT-PCR indications are sporadic gastroenteritis case patients, negative NoV and RV ICT during outbreaks, control of positive RV ICT in cases of suspected NoV and RV co-circulation, patients with long symptom duration, and NoV genogroup and genotype identifications (infection control and epidemiological surveillance). Inclusion of patients with specific clinical symptoms is recommended irrespective of the technique. CONCLUSION: On the basis of the ICT limits identified in this work, RT-PCR development seems essential to improve viral gastroenteritis investigations in institutions caring for dependent people.

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: Silver-based products have been marketed as an alternative to antibiotics, and their consumption has increased. Bacteria may, however, develop resistance to silver. AIM: To study the presence of genes encoding silver resistance (silE, silP, silS) over time in three clinically important Enterobacteriaceae genera. METHODS: Using polymerase chain reaction (PCR), 752 bloodstream isolates from the years 1990-2010 were investigated. Age, gender, and ward of patients were registered, and the susceptibility to antibiotics and silver nitrate was tested. Clonality and single nucleotide polymorphism were assessed with repetitive element sequence-based PCR, multi-locus sequence typing, and whole-genome sequencing. FINDINGS: Genes encoding silver resistance were detected most frequently in Enterobacter spp. (48%), followed by Klebsiella spp. (41%) and Escherichia coli 4%. Phenotypical resistance to silver nitrate was found in Enterobacter (13%) and Klebsiella (3%) isolates. The lowest carriage rate of sil genes was observed in blood isolates from the neonatology ward (24%), and the highest in blood isolates from the oncology/haematology wards (66%). Presence of sil genes was observed in international high-risk clones. Sequences of the sil and pco clusters indicated that a single mutational event in the silS gene could have caused the phenotypic resistance. CONCLUSION: Despite a restricted consumption of silver-based products in Swedish health care, silver resistance genes are widely represented in clinical isolates of Enterobacter and Klebsiella species. To avoid further selection and spread of silver-resistant bacteria with a high potential for healthcare-associated infections, the use of silver-based products needs to be controlled and the silver resistance monitored.

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.

Bacteroides vulgatus is a member of the human microbiota whose abundance is increased in patients with Crohn's disease. We show that a B. vulgatus glycoside hydrolase from the carbohydrate active enzyme family GH123, BvGH123, is an N-acetyl-ß-galactosaminidase that acts with retention of stereochemistry, and, through a 3-D structure in complex with Gal-thiazoline, provide evidence in support of a neighbouring group participation mechanism.

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: 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.

We investigated a four-generation family of German ancestry with distal myopathy. Four individuals in two generations were affected. Foot and toe extensor paresis progressing very slowly over decades was the core neurological sign, reflected by fatty infiltration of the lower leg extensor muscles on muscle MRI. Additionally, finger extensor paresis was present in two patients and quadriceps muscle paresis in one. Distal sensory signs had initially given rise to the diagnosis of axonal Charcot-Marie-Tooth (CMT) disease. Two patients had extended verrucae of their foot sole, which may or may not be part of the disease spectrum. All four patients had a novel c.4645G > C mutation in exon 34 of the MYH7 gene that was not present in three clinically unaffected family members. Muscle biopsy of one patient revealed a myopathic pattern associated with type 1 muscle fibre atrophy and core-like lesions in many muscle fibres consistent with a myosin-related myopathy. We conclude that some of the typical clinical signs such as extensor weakness of the big toe and the little finger may only develop in the further course of the disease.

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 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: 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.
