Web Survey of Society Members' Recognition of Guidelines for the Diagnosis and Treatment of Helicobacter pylori Infection in Korea, 2013 Revised Edition

2 , Incheon, Korea Background/Aims: We aimed to evaluate recognition of the 2013 revised guidelines for diagnosis and treatment of Helicobacter py- lori infection in Korea by members of the society through a web survey. Materials and Methods: We analyzed the respondents' agreement with the 19 guidelines in terms of awareness and adherence. Among 718 physicians, 149 (20.8%) answered the questionnaire by e-mail between October and November 2013. Results: The mean age of the respondents was 40±7 years, and the ratio of men to women were 74.5:25.5. The respondents were as follows: professors (36.2%), fellows (31.5%), salaried doctors (17.4%), private practitioners (11.4%), and screening center clini- cians (3.4%). Among the 141 respondents, 69.1% had read, 17.3% agreed completely, and 77.3% agreed generally with the guidelines. The respondents indications for eradication were peptic ulcer disease (77.2%), MALT lymphoma (89.3%), and follow- ing endoscopic therapy for early gastric cancer (71.1%). However, 42.3% and 48.3% of the physicians administered H. pylori erad- ication treatment for patients with atrophic gastritis and a family history of gastric cancer, respectively. Triple therapy as first line regimens was administered by 81.2% of the respondents. The duration was one-week for 77.7% and two-weeks for 13.4%. A total of 55.7% prescribed a bismuth-based secondary treatment. When bismuth-based initial therapy failed, a combination of 2 anti- biotics that were not used as first-line therapy were used (37.6%). Conclusions: This web survey was very helpful for analyzing society members' recognition of 2013 revised guidelines. Generally, all the society members followed the guidelines.

Neurophysiological patterns of vegetative and minimally conscious states

This paper reviews the possible usefulness of electroencephalogram (EEG) and evoked potential (EP) recording in vegetative and poorly-responsive patients. There is a marked inter-individual EEG and EP variability, which reflects the state heterogeneity. Four clinical applications are described: (1) the identification of primary midbrain dysfunction—and, therefore, a possible reversibility—in post-traumatic states; (2) the identification of the permeability of sensory channels; (3) quantitative follow-up; and (4) individual assessment of cognitive functions and/or consciousness. Regarding this last issue, the loss of primary cortical EPs, although rarely observed, constitutes one major argument against consciousness. Conversely, cognitive EPs definitely proved the persistence of cognitive functions in several vegetative patients. Whether these cognitive functions are conscious or not remains a matter of debate.
Epidemiology, Diagnosis, and Management of Neurogenic Orthostatic Hypotension

Orthostatic hypotension (OH) is a sustained fall in blood pressure on standing that can cause symptoms of organ hypoperfusion. OH is associated with increased morbidity and mortality and leads to a significant number of hospital admissions, particularly in the elderly (233 per 100,000 patients >75 years of age in the United States). OH can result from volume depletion, blood loss, large varicose veins, medications, or because of defective activation of sympathetic nerves and reduced norepinephrine release on standing (i.e., neurogenic OH).
Reduction of hypoxia by perfluorocarbon emulsion in a traumatic spinal cord injury model.

OBJECT Few therapies have consistently demonstrated effectiveness in preserving O2 delivery after spinal cord injury (SCI). Perfluorocarbons (PFCs) offer great promise to carry and deliver O2 more efficiently than conventional measures. The authors investigated the use of Clark-type microelectrodes to monitor spinal cord oxygenation directly (intraparenchymal [IP] recording) and indirectly (cerebrospinal fluid [CSF] recording) in the context of SCI, O2 therapy, and PFC treatment. METHODS After placement of a subdural/CSF Licox probe in rats, incremental increases in the fraction of inspired O2 (FiO2) up to 100% were administered to establish a dose-response curve. The probe was then placed in the parenchyma of the same animals for a second dose-response curve. In a second study, rats with CSF or IP probes underwent SCI with the NYU Impactor and treatment with O2, followed by administration of PFC, or saline in the control group. RESULTS All animals in the first experiment responded to the FiO2 dose increase, with changes in PO2 evident in both CSF and IP levels. The SCI in the second experiment caused a marked drop in PO2 from a mean of 21.4 to 10.4 mm Hg, with most animals dropping to less than half their preinjury value. All animals responded to 100% O2 treatment. Every animal that received PFCs showed significant improvement, with a mean increase in PO2 of 23.3 mm Hg. Only 1 saline-treated animal showed any benefit. Oxygen values in the PFC treatment group reached up to 6 times the normal level. CONCLUSIONS Oxygen levels in SCI show a profound drop almost immediately postinjury. Administration of PFCs combined with 100% O2 therapy can reverse tissue hypoxia and holds promise for reducing ischemic injury.
Factors Affecting a Clinician's Decision to Provide Fieldwork Education to Students

Fieldwork represents an important component of the education of an occupational therapist. In this study thirteen occupational therapists in small Saskatchewan occupational therapy facilities were interviewed to determine the factors and the relationships among these factors that affected their involvement in the fieldwork process. The directors of the two large occupational therapy departments in Saskatchewan, together with eight Canadian university fieldwork coordinators were interviewed for comparison purposes. The findings of the study have shown that there were four major influences affecting Saskatchewan therapists' involvement in the fieldwork program of occupational therapy students. They were: workload: feelings of isolation; the parameters of a placement: and professionalism. This study is important because it has identified significant factors for university fieldwork coordinators to consider in their contact with therapists. It has also provided a model for other similar studies.
Combining latent class analysis labeling with multiclass approach for fetal heart rate categorization

The most common approach to assess fetal well-being during delivery is monitoring of fetal heart rate and uterine contractions—the cardiotocogram (CTG). Nevertheless, 40 years since the introduction of CTG to clinical practice, its evaluation is still challenging with high inter- and intra-observer variability. Therefore the development of more objective methods has become an issue of major importance in the field. Unlike the usually proposed approaches to assign classes for classification methods that rely either on biochemical parameters (e.g. pH value) or a simple aggregation of expert judgment, this work investigates the use of an alternative labeling system using latent class analysis (LCA) along with an ordinal classification scheme. The study is performed on a well-documented open-access database, where nine expert obstetricians provided CTG annotations. The LCA is proposed here to produce more objective class labels while the ordinal classification aims to explore the natural ordering, and representation of increased severity, for obtaining the final results. The results are promising suggesting that more effort should be put into this proposed approach.
FROM TRISECTIONS IN MODULE CATEGORIES TO QUASI-DIRECTED COMPONENTS

In this paper, we define and study a special type of trisections in a module category, namely the compact trisections which characterize quasi-directed components. We apply this notion to the study of laura algebras and we use it to define a class of algebras with predictable Auslander–Reiten components.
Cerebello-thalamic synapses and motor adaptation

The cerebellum’s influence on voluntary movement is mediated, in large part, through the cerebello-thalamo-cortical (CTC) pathway. Of particular relevance here are those neurons in the cerebellar nuclei that project, via thalamus, to pyramidal tract neurons in primary motor cortex. Several lines of evidence implicate cerebello-thalamic (CT) synaptic plasticity as a neural substrate underlying movement adaptation in adult animals. CT synapses exhibit a number of structural characteristics suggestive of a capacity for both formation of new synapses, and alterations in efficacy of transmission across existing synapses. Long-term potentiation can be evoked across CT synapsesin vitro by high frequency stimulation, albeit in young animals. Evidence regarding the contribution of CT synaptic plasticity to two different types of movement adaptation in adult animals is conflicting. Adaptation involving a strengthening and re-coordination of voluntary movement is associated with an increase in density of CT synaptic boutons and an increase in number of synaptic vesicles available for immediate neurotransmitter release within each bouton. On the other hand, adaptation involving associative conditioning of a reduced sensorimotor neural circuit is associated with plasticity at thalamo-cortical but not CT synapses. These conflicting findings may reflect differences in the extent of synaptic re-organization that occurs at thalamic versus cortical levels, differences in the neural circuitry mediating each behavior, and/or differences in the spatio-temporal convergence of activity in the thalamus during the adaptive processes. It is concluded that CT synaptic plasticity can underlie movement adaptation if the adaptation requires reorganization of the cerebellum’s influence on cerebral cortex.
The Effects of a Mutant Connexin 26 on Epidermal Differentiation

To elucidate the mode of action of dominant mutant connexins in causing inherited skin diseases, transgenic mice were produced that express the true Vohwinkel syndrome-associated mutant Cx26 (D66H), from a keratin 10 promoter, specifically in the suprabasal epidermal keratinocytes. Following birth, the transgenic mice developed keratoderma similar to that of human carriers of Cx26 (D66H). Expression of the transgene resulted in a loss of Cx26 and Cx30 at intercellular junctions of epidermal keratinocytes and accumulation of these connexins in the cytoplasm. Injection of primary mouse keratinocytes with Lucifer Yellow showed no difference in terms of dye spreading between transgenic and non transgenic keratinocytes in vitro. Expression of the mutant Cx26 (D66H) did not interfere with the formation of the epidermal water barrier during late embryonic development. Attempts to produce transgenic mice expressing the wild type form of Cx26 from the K10 promoter failed to produce viable animals although transgenic embryos were recovered at days 9 and 12 of gestation, suggesting that the transgene might be embryonic lethal.
Impact of tirofiban on angiographic morphologic features of high-burden thrombus formation during direct percutaneous coronary intervention and short-term outcomes.

BACKGROUND Recently, we demonstrated that angiographic morphologic features of high-burden thrombus formation are independent predictors of combined slow flow (ie, Thrombolysis in Myocardial Infarction [TIMI] grade 2) and no reflow (ie, </= TIMI grade 1) in the infarct-related artery (IRA) after direct percutaneous coronary intervention (d-PCI) for the treatment of acute myocardial infarction (AMI). Current data have demonstrated that when administered in conjunction with PCI for acute coronary syndrome, platelet glycoprotein IIb/IIIa inhibitors can provide additional clinical benefits. Thus, we hypothesized that after pretreatment with tirofiban, angiographic morphologic features of high-burden thrombus formation would no longer be independent predictors of combined slow flow and no reflow after treatment with d-PCI. METHODS AND RESULTS Between January 2001 and April 2002, tirofiban was administered to 210 consecutive patients with ST-segment elevated AMI before coronary angiography was performed, and 84 patients (40.0%) were found to have high-burden thrombus formation in the IRA. The TIMI flow grade of the IRA was assessed immediately after the performance of d-PCI, and the 30-day clinical outcomes were evaluated prospectively. The incidence of restoration of normal coronary flow in the IRA was 83.6%. Three baseline angiographic morphologic features indicating high-burden thrombus formation, including (1) the cutoff pattern of occlusion in the IRA (p = 0.0001), (2) the accumulated thrombus proximal to the occlusion (p = 0.0001), and (3) a reference lumen diameter of the IRA of > or = 4.0 mm (p = 0.001), were independent predictors of combined slow flow and no reflow. In stratified analysis, the rates of slow flow and no reflow after d-PCI rose rapidly as the number of independent predictors increased (0 predictors, 3.8%; 1 predictor, 29.0%; and 2 predictors, 70.6%). The overall 30-day mortality rate was 6.7%. The mortality rate was significantly higher in patients with TIMI flow lower than or equal to grade 2 than in those with TIMI grade 3 flow (15% vs 1.3%, respectively; p = 0.003). CONCLUSIONS Tirofiban did not provide additional clinical benefits when administered in conjunction with d-PCI for AMI, even in the subgroup of patients with a high-burden thrombus. Those distinct angiographic morphologic features of high-burden thrombus formation remained as independent predictors of combined slow flow and no reflow after d-PCI, and were independent of the use of tirofiban.
Ganglioside GD3 Traffics from the trans-Golgi Network to Plasma Membrane by a Rab11-independent and Brefeldin A-insensitive Exocytic Pathway*

Gangliosides, complex glycosphingolipids containing sialic acids, have been found to reside in glycosphingolipid-enriched microdomains (GEM) at the plasma membrane. They are synthesized in the lumen of the Golgi complex and appear unable to translocate from the lumenal toward the cytosolic surface of Golgi membrane to access the monomeric lipid transport. As a consequence, they can only leave the Golgi complex via the lumenal surface of transport vesicles. In this work we analyzed the exocytic transport of the disialo ganglioside GD3 from trans-Golgi network (TGN) to plasma membrane in CHO-K1 cells by immunodetection of endogenously synthesized GD3. We found that ganglioside GD3, unlike another luminal membrane-bounded lipid (glycosylphosphatidylinositol-anchored protein), did not partition into GEM domains in the Golgi complex and trafficked from TGN to plasma membrane by a brefeldin A-insensitive exocytic pathway. Moreover, a dominant negative form of Rab11, which prevents exit of vesicular stomatitis virus glycoprotein from the Golgi complex, did not influence the capacity of GD3 to reach the cell surface. Our results strongly support the notion that most ganglioside GD3 traffics from the TGN to the plasma membrane by a non-conventional vesicular pathway where lateral membrane segregation of vesicular stomatitis virus glycoprotein (non-GEM resident) and glycosylphosphatidylinositol-anchored proteins (GEM resident) from GD3 is required before exiting TGN.
Dynamic Resistance—A Metric for Variability Characterization of Phase-Change Memory

The resistance of phase-change-memory (PCM) cells measured during RESET programming (dynamic resistance, Rd) is found to be inversely proportional to the amplitude of the programming current, as Rd = [A/I] + B. We show that parameters A and B are related to the intrinsic properties of the memory cell, and demonstrate by means of experimental data that they could be used to characterize the cell-to-cell process-induced variability of PCM cells.
Design of self powered chip integrated humidity sensor

This paper presents a low power wireless capacitive based CMOS humidity sensor to be used in Internet of Things (IoT)applications, powered through inductive coupling. The sensing element is implemented in standard CMOS technology with minimum post processing step. This sensor is based on the detection of change in frequency due to the change in humidity levels. The proposed humidity sensor is designed in 0. 18μm Global Foundries process. The simulated results show that even a change of as small as 50fF in the sensing element is detected, indicating high sensitivity. This chip consumes around 600μW of total power at 1.5V.
The utility of cervical elastosonography in prediction of cervical insufficiency: cervical elastosonography and cervical insufficiency

Abstract Objective: To evaluate the utility of cervical elastosonography (ES) in prediction of cervical insufficiency (CI). Methods: A total of 40 women, of which 20 who had previously received the diagnosis of CI and 20 healty women were included in the study. None of the women were pregnant. All subjects underwent sonographic evaluation including cervical length measurement and ES of uterine cervix. Adjacent muscular tissue was the reference point for elastosonography evaluation. Tissue strain ratio values were obtained from all the patients. Results: The area around the internal cervical os of the group with CI was found to be significantly softer as compared to the control group (higher SR rate, p < 0.05). Furthermore, the outer parts of the cervix (sites A and D) were also found harder in the group that had CI (lower SR rate, p < 0.05). Conclusions: According to our knowledge, this is preliminary study to evaluate the predictive value of cervical ES in CI and we concluded that ES can be used as reliable method to determine CI but it is necessary to be studied in different cohort groups.
Effects of 12-Week Medicine Ball Training on Muscle Strength and Power in Young Female Handball Players

Abstract Ignjatovic, AM, Markovic, ZM, and Radovanovic, DS. Effects of 12-week medicine ball training on muscle strength and power in young female handball players. J Strength Cond Res 26(8): 2166–2173, 2012—The purpose of this study was to examine the effects of medicine ball training on the strength and power in young female handball athletes. Twenty-one young female handball players (age, 16.9 ± 1.2 years) were randomly assigned to experimental and control groups. Experimental group (n = 11) participated in a 12-week medicine ball training program incorporated into the regular training session, whereas controls (n = 10) participated only in the regular training. Performance in the medicine ball throws in standing and sitting positions, 1 repetition maximum (1RM) bench and shoulder press, and power test at 2 different loads (30 and 50% of 1RM) on bench and shoulder press were assessed at pre- and posttraining testing. The athletes participating in the medicine ball training program made significantly greater gains in all medicine ball throw tests compared with the controls (p < 0.01). Also, the experimental group made significantly greater gains in bench and shoulder press power than control group (p < 0.05). Both training groups (E) and (C) significantly (p < 0.05) increased 1RM bench and shoulder strength, with no differences observed between the groups. Additionally, medicine ball throw tests showed stronger correlation with power tests, than with 1RM tests. These data suggest that 12-week medicine ball training, when incorporated into a regular training session, can provide greater sport-specific training improvements in the upper body for young female handball players.
Suppression of Pleiotropic Effects of Functional CRYPTOCHROME Genes by TERMINAL FLOWER 1

TERMINAL FLOWER 1 (TFL1) encodes a protein with similarity to animal phosphatidylethanolamine-binding proteins and is required for normal trafficking to the protein storage vacuole. In Arabidopsis thaliana the tfl1 mutation produces severe developmental abnormalities. Here we show that most aspects of the tfl1 phenotype are lost in the cry1 cry2 double-mutant background lacking cryptochromes 1 and 2. The inhibition of hypocotyl growth by light is reduced in the tfl1 mutant but this effect is absent in the cry1 or cry2 mutant background. Although the promotion of flowering under long rather than short days is a key function of cryptochromes, in the tfl1 background, cryptochromes promoted flowering under short days. Thus, normal CRY control of photoperiod-dependent flowering and hypocotyl growth inhibition requires a functional TFL1 gene.
Sacroiliac joint interventions: a systematic review.

BACKGROUND The sacroiliac joint is a diarthrodial synovial joint with abundant innervation and capability of being a source of low back pain and referred pain in the lower extremity. There are no definite historical, physical, or radiological features to provide definite diagnosis of sacroiliac joint pain, although many authors have advocated provocational maneuvers to suggest sacroiliac joint as a pain generator. An accurate diagnosis is made by controlled sacroiliac joint diagnostic blocks. The sacroiliac joint has been shown to be a source of pain in 10% to 27% of suspected cases with chronic low back pain utilizing controlled comparative local anesthetic blocks. Intraarticular injections, and radiofrequency neurotomy have been described as therapeutic measures. This systematic review was performed to assess diagnostic testing (non-invasive versus interventional diagnostic techniques) and to evaluate the clinical usefulness of interventional techniques in the management of chronic sacroiliac joint pain. OBJECTIVE To evaluate and update the available evidence regarding diagnostic and therapeutic sacroiliac joint interventions in the management of sacroiliac joint pain. STUDY DESIGN A systematic review using the criteria as outlined by the Agency for Healthcare Research and Quality (AHRQ), Cochrane Review Group Criteria for therapeutic interventions and AHRQ, and Quality Assessment for Diagnostic Accuracy Studies (QUADAS) for diagnostic studies. METHODS The databases of EMBASE and MEDLINE (1966 to December 2006), and Cochrane Reviews were searched. The searches included systematic reviews, narrative reviews, prospective and retrospective studies, and cross-references from articles reviewed. The search strategy included sacroiliac joint pain and dysfunction, sacroiliac joint injections, interventions, and radiofrequency. RESULTS The results of this systematic evaluation revealed that for diagnostic purposes, there is moderate evidence showing the accuracy of comparative, controlled local anesthetic blocks. Prevalence of sacroiliac joint pain is estimated to range between 10% and 27% using a double block paradigm. The false-positive rate of single, uncontrolled, sacroiliac joint injections is around 20%. The evidence for provocative testing to diagnose sacroiliac joint pain is limited. For therapeutic purposes, intraarticular sacroiliac joint injections with steroid and radiofrequency neurotomy were evaluated. Based on this review, there is limited evidence for short-term and long-term relief with intraarticular sacroiliac joint injections and radiofrequency thermoneurolysis. CONCLUSIONS The evidence for the specificity and validity of diagnostic sacroiliac joint injections is moderate. The evidence for accuracy of provocative maneuvers in diagnosis of sacroiliac joint pain is limited. The evidence for therapeutic intraarticular sacroiliac joint injections is limited. The evidence for radiofrequency neurotomy in managing chronic sacroiliac joint pain is limited.
