    Objective: To measure and define the distribution of left gastric lymph nodes. Methods: From Jan. 2004 to Apr. 2005, silver clips were set around the root of the left gastric artery in 124 patients with esophageal and gastric cardia carcinoma, X-ray films at 0 degree and 90 degree simulator gantry in the radio- therapeutic position were taken. Then, the data of the superior, lower, left, right, anterior and posterior bor- der in each patient was recorded. With SAS 8.02 software, data of minimum area which covered the left gastric lymph node in different incidences were obtained. Results: According to the analysis of Shapiro-Wilk, Kolmogorov-Smimov, Cramervon Mises and Anderson-Darling tests, each border' was of normal distribution, with equal frequency in the male and female, despite the actual results in different genders. Pearson Correlation Coefficients analysis did not suggest a significant relationship between the border and height, weight and size of vertebrae, which formed the minimum area covering the left gastric area at frequency of 100%, 95%, 90% and 85%, which were drawn out through the calculation. Conclusions: Aiming at completely identifying the normal distribution of the left gastric lymph node, more patients are required to be in the pool. For the time being, location in the left gastric area can be obtained from details of the results in the present study. (authors)

    We have previously reported an automated approach to detection of endocardial and epicardial borders in individual intracardiac ultrasound (ICUS) images. Here, we report the method's extension to 3D ICUS image data sets. Our method is based on fully automated detection of epicardial and endocardial borders inside a single interactively identified region of interest. BOrder detection is based on an optimal graph-searching approach that utilizes a priori knowledge about left ventricular (LV) anatomy and ultrasound imaging physics. Eight cadaveric pig hearts were used for validation. Two ICUS sequences were obtained from each heart, with a 10 MHz CVIS 10F catheter positioned in the LV across (1) the aortic valve and (2) the mitral valve. Performance of the 3D automated border detection method was assessed by comparing the observer- defined and computer-determined quantitative indices of LV volume and by border positioning errors. The 3D reconstruction of the lV was performed from the sequences of the detected epicardial and endocardial borders using shape- based interpolation and surface rendering.

    Full Text Available Sternal mycobacterial infections are rare. Due to the rarity, its clinical characteristics, diagnoses, and regular management strategies are still scanty. A total of 76 articles on this topic were obtained by a comprehensive literature collection. The clinical features, diagnosis, management strategies and prognosis were carefully analyzed. There were totally 159 patients including 152 (95% cases of tuberculosis (TB and seven (5% cases of non-TB sternal infections. Sternal mycobacterial infections can be categorized into three types: Primary, secondary, and postoperative, according to the pathogenesis; and categorized into isolated, peristernal, and multifocal, according to the extent of the lesions. Microbiological investigation is more sensitive than medical imaging and Mantoux tuberculin skin test in the diagnosis of sternal infections. Most patients show good responses to the standard four-drug regimen and a surgical intervention was necessary in 28.3% patients. The prognoses of the patients are good with a very low mortality. A delayed diagnosis of sternal mycobacterial infections may bring about recurrent sternal infections and sustained incurability. An early diagnosis and prompt antibiotic regimens may significantly improve the patients' outcomes.

    2016-01-01

    Sternal variations and anomalies have been identified in the past during autopsy or cadaveric studies. Recently, an increasing number of minor sternal variations have been reported with the advent of multidetector computed tomography (CT). Although there are many sternal variations that occur with varying appearance and prevalence, most of them are not recognized or are underreported during routine imaging of thorax. Identification of sternal variations is important to differentiate from pathological conditions and to prevent fatal complications prior to sternal interventions like marrow aspiration or acupuncture. This article aims to describe the minor and asymptomatic sternal variations by multidetector CT and their clinical significance

    Full Text Available A 61-year-old female was brought in by ambulance after being the restrained driver of a head-on motor vehicle collision at 40MPH. There was positive airbag deployment and intrusion from the other vehicle. During workup, the patient complained of midline chest pain, and left chest wall pain. The patient was not in acute respiratory distress, and had the following vital signs: temperature 37°C, heart rate 84, blood pressure of 150/64, respiratory rate 18, and oxygen saturation of 97% on two liters of oxygen. On physical exam, breath sounds were heard bilaterally, with no acute cardiopulmonary issues identified. A bruise was identified on the lower abdomen, which was thought to be a potential seatbelt sign. A focused assessment with sonography for trauma was negative, and an ultrasound of additional chest and mediastinal structures was performed for the chest tenderness.

    Full Text Available Abstract Background Deep sternal wound complications are uncommon after cardiac surgery. They comprise sternal dehiscence, deep sternal wound infections and mediastinitis, which will be treated as varying expressions of a singular pathology for reasons explained in the text. Methodology and review This article reviews the definition, prevalence, risk factors, prevention, diagnosis, microbiology and management of deep sternal wound infections and mediastinitis after cardiac surgery. The role of negative pressure wound therapy and initial and delayed surgical management is discussed with special emphasis on plastic techniques with muscle and omental flaps. Recent advances in reconstructive surgery are presented. Conclusions Deep sternal wound complications no longer spell debilitating morbidity and high mortality. Better understanding of risk factors that predispose to deep sternal wound complications and general improvement in theatre protocols for asepsis have dramatically reduced the incidence of deep sternal wound complications. Negative pressure wound therapy and appropriately timed and staged muscle or omental flap reconstruction have transformed the outcomes once these complications occur.

    Skeletal abnormalities such as hypertrophic callus formation and ''popcorn'' calcifications are rare radiological findings of osteogenesis imperfecta, causing tumor-like appearances on imaging. We report on a 7-year-old girl with osteogenesis imperfecta presenting with hepatomegaly and palpable lymphadenopathy in the left inguinal region on physical examination. Computed tomography examination revealed a high-density mass-like lesion of the manubrium sterni. Ultrasonography and a lateral roentgenogram of the chest verified that this was a pseudomass caused by a bowed sternal manubrium. (orig.)

    In a retrospective review of bone scans performed in 1740 patients with breast cancer from January 1988 to April 1993, twenty had a solitary sternal lesion. Etiology was found correlating this finding with pathology, x-rays and/or final outcome. Nineteen lesions were due to metastases and one to infection. This experience suggests that solitary sternal lesions in breast cancer patients are uncommon and are most frequently (95%) associated with malignant etiology. (Authors). 10 refs., 2 figs

    Full Text Available Abstract Background Median sternotomy infection and bony nonunion are two commonly described complications which occur in 0.4 - 5.1% of cardiac procedures. Although relatively infrequent, these complications can lead to significant morbidity and mortality. The aim of this retrospective study is to evaluate the initial experience of a transverse plate fixation system following wound complications associated with sternal dehiscence with or without infection following cardiac surgery. Methods A retrospective chart review of 40 consecutive patients who required sternal wound reconstruction post sternotomy was performed. Soft tissue debridement with removal of all compromised tissue was performed. Sternal debridement was carried using ronguers to healthy bleeding bone. All patients underwent sternal fixation using three rib plates combined with a single manubrial plate (Titanium Sternal Fixation System®, Synthes. Incisions were closed in a layered fashion with the pectoral muscles being advanced to the midline. Data were expressed as mean ± SD, Median (range or number (%. Statistical analyses were made by using Excel 2003 for Windows (Microsoft, Redmond, WA, USA. Results There were 40 consecutive patients, 31 males and 9 females. Twenty two patients (55% were diagnosed with sternal dehiscence alone and 18 patients (45% with associated wound discharge. Thirty eight patients went on to heal their wounds. Two patients developed recurrent wound infection and required VAC therapy. Both were immunocompromised. Median post-op ICU stay was one day with the median hospital stay of 18 days after plating. Conclusion Sternal plating appears to be an effective option for the treatment of sternal wound dehiscence associated with sternal instability. Long-term follow-up and further larger studies are needed to address the indications, benefits and complications of sternal plating.

    To improve the quantification of the left ventricular surface area (LVSA) by unfolded map method, we evaluated the cut-off value for determining the left ventricular border. The LVSA measured by unfolded map was compared with those measured using myocardial phantom and autopsy findings. The relative error (RE) was calculated as difference between LVSA in phantom and area of unfolded map. In phantom study, the cut-off value was calculated as 73.3±0.5% when the RE was zero. In autopsy study, the cut-off value was 74.0±7.2%. The area of unfolded map had good correlation with LVSA at autopsy when the cut-off value was 74% (r=0.83, p<0.003). The diameter of left ventricle at autopsy was compared with that of beating heart obtained by two-dimensional echocardiography, because the area of unfolded map was greater than LVSA at autopsy. The ratio of LVSA at autopsy to beating heart was calculated as 1.37. The suitable cut-off value was evaluated as 55.6% when the unfolded map area obtained by autopsy was increased 1.37 magnifications. There was a good correlation between LVSA of unfolded map (cut-off=56%) and the LVSA at autopsy (r=0.90, p<0.001). These results suggest that the cut-off value for determining the left ventricular border in vivo is 56%. (author)

  16. Molecular analysis of Agrobacterium T-DNA integration in tomato reveals a role for left border sequence homology in most integration events.

    Studies in several plants have shown that Agrobacterium tumefaciens T-DNA can integrate into plant chromosomal DNA by different mechanisms involving single-stranded (ss) or double-stranded (ds) forms. One mechanism requires sequence homology between plant target and ssT-DNA border sequences and another double-strand-break repair in which preexisting chromosomal DSBs "capture" dsT-DNAs. To learn more about T-DNA integration in Solanum lycopersicum we characterised 98 T-DNA/plant DNA junction sequences and show that T-DNA left border (LB) and right border transfer is much more variable than previously reported in Arabidopsis thaliana and Populus tremula. The analysis of seven plant target sequences showed that regions of homology between the T-DNA LB and plant chromosomal DNA plays an important role in T-DNA integration. One T-DNA insertion generated a target sequence duplication that resulted from nucleolytic processing of a LB/plant DNA heteroduplex that generated a DSB in plant chromosomal DNA. One broken end contained a captured T-DNA that served as a template for DNA repair synthesis. We propose that most T-DNA integrations in tomato require sequence homology between the ssT-DNA LB and plant target DNA which results in the generation of DSBs in plant chromosomal DNA.

    The aim of this study was to evaluate the safe zone for performing blind sternal procedures based on computed tomography (CT) evaluation of congenital midline sternal foramina using multidetector computed tomography (MDCT). This retrospective study was carried out on 1,180 patients who underwent MDCT of the thorax from March 2015 to February 2016. The MDCT images were evaluated in axial and reformatted planes. Morphometry and prevalence of midline congenital sternal foramina (SF) and manubrio-foraminal distance (MFD) were evaluated. The safe zone was defined for a blinded intervention, based on palpable anatomical landmarks. Data were presented in terms of percentage, mean ± standard deviation and calculations were carried out using Microsoft Excel. The prevalence of SF in our study sample was 11.6 %. The majority of SF were located in a typical position in the lower sternal body at the level of fifth costo-chondral junction (CCJ) in 108 patients (78.8 %). The structure directly beneath the SF was mediastinal fat in 73 patients (53.3 %), followed by anterior pericardium in 44 patients (32.1 %) and lung parenchyma in 20 patients (14.6 %). The mean MFD in our study population was 11.90 ± 1.31 cm. Sternal interventions should be avoided at the level of fourth to sixth CCJ, which is considered the danger zone. An intervention at the fourth to sixth CCJ may lead to disastrous consequences in patients who have SF. (orig.)

    The influence of sternal size and of inadvertent paramedian sternotomy on stability of the closure site is not well defined. Data on 171 consecutive patients undergoing cardiac surgery through a midline sternotomy were prospectively collected. Intraoperative measurements of sternal dimension included thickness and width at the manubrium, the third and fifth intercostal spaces; paramedian sternotomy was defined as width of one side of the sternum equaling 75% or more of the entire width, at any of the three levels. The chest was closed with simple peristernal steel wires and inspected to detect deep wound infection and/or instability for 3 postoperative months. The sternal factors and several patient/surgery-related factors were included in a multivariate analysis model to identify factors affecting stability. An electromechanical traction test was conducted on 6 rewired sternal models after midline or paramedian sternotomy and separation data were analyzed. Chest instability was detected in 12 (7%) patients and wound infection in 2 (1.2%). Patient weight (P = .03), depressed left ventricular function (P = .04), sternum thickness (indexed to body weight, P = .03), and paramedian sternotomy (P = .0001) were risk factors of postoperative instability; paramedian sternotomy was the only independent predictor (P = .001). The electromechanical test showed more lateral displacement of the two rewired sternal halves after paramedian than midline sternotomy (P = .002); accordingly, load at fracture point was lower after paramedian sternotomy (220 +/- 20 N vs 545 +/- 25 N, P = 0.001). Inadvertent paramedian sternomoty strongly affects postoperative chest wound stability independently from sternal size, requiring prompt reinforcement of chest closure.

    Brown adipose tissue acting through a unique uncoupling protein (UCP1) has a critical role in preventing hypothermia in newborn sheep but is then thought to rapidly disappear during postnatal life. The extent to which the anatomical location of fat influences postnatal development and thermogenic function in adulthood, particularly following feeding, is unknown, and we examined both in our study. Changes in gene expression of functionally important pathways (i.e., thermogenesis, development, adipogenesis, and metabolism) were compared between sternal and retroperitoneal fat depots together with a representative skeletal muscle over the first month of postnatal life, coincident with the loss of brown fat and the accumulation of white fat. In adult sheep, implanted temperature probes were used to characterize the thermogenic response of fat and muscle to feeding and the effects of reduced or increased adiposity. UCP1 was more abundant in sternal fat than in retroperitoneal fat and was retained only in the sternal depot of adults. Distinct differences in the abundance of gene pathway markers were apparent between tissues, with sternal fat exhibiting some similarities with muscle that were not apparent in the retroperitoneal depot. In adults, the postprandial rise in temperature was greater and more prolonged in sternal fat than in retroperitoneal fat and muscle, a difference that was maintained with altered adiposity. In conclusion, sternal adipose tissue retains UCP1 into adulthood, when it shows a greater thermogenic response to feeding than do muscle and retroperitoneal fat. Sternal fat may be more amenable to targeted interventions that promote thermogenesis in large mammals. Copyright © 2017 Endocrine Society.

    2010-08-01

    In 2004, we published our 12-year experience with tissue transfer for deep sternal wound infection after median sternotomy, finding increased rates of reoperation for diabetic patients. Therefore, we decided to alter our treatment approach to diabetic patients to include sternal debridement followed by omental transposition. Eleven diabetic patients underwent omental transposition by our division during the study period. Hospital records were retrospectively reviewed to determine outcomes and complications. We found that diabetic patients treated after implementation of the new treatment approach were 5.4 times less likely to require reoperation for sternal wound management than were patients in the previous series, most of whom had been treated with pectoralis muscle flaps (95% confidence interval, 0.5- 50.5). By altering our treatment approach to use omental transposition as the initial surgical therapy, we were able to demonstrate a trend toward decreased need for flap revision in diabetic patients.

    Full Text Available Injury of the heart with concomitant pericardial tamponade as a result of sternal bone marrow biopsy is rare. An 80-year-old man was admitted with dehydration and non-specified abdominal pain to the regional hospital. Sternal aspiration biopsy was performed because of anemia and thrombocytopenia. Later on, because of the back pain, general weakness and blood pressure drop, an echocardiography examination was indicated. Pericardial fluid collection was found. Anticipated ascending aortic dissection was excluded on computed tomography scan, but pericardial fluid collection was confirmed. Transfer to our cardiac surgical facility ensued. Limited heart tamponade was affirmed on echocardiography and surgery was immediately indicated. Blood effusion was found in upper mediastinal fat tissue and 300 mL of blood were evacuated from opened pericardial space. Stab wound by sternal biopsy needle at the upper part of ascending aorta was repaired by pledgeted suture. Postoperative course was uneventful.

    To define the classification of sternal wound complications after cardiac surgery and to explore the appropriate surgical treatment. Between July 2008 and January 2014, 260 patients with sternal wound complications after cardiac surgery were treated. There were 124 males and 136 females, aged 11-75 years (mean, 49.5 years). The disease duration was 13-365 days (mean, 26.6 days) with a wound length of 1-25 cm (mean, 13.4 cm). The wounds were divided into type I (n = 70), type II (n = 64), type III (n = 42), type IV (n = 78), and type V (n = 6) according to self-generated classification for sternal wound complications after cardiac surgery. After debridement, wounds of type I and type II were repaired with local flap transplantation; wounds of type III were repaired with local flap transplantation combined with butterfly sternal fixation (n = 28), with bilateral pectoralis muscle flap combined with butterfly sternal fixation (n = 11), and with bilateral pectoralis muscle flap (n = 3); wounds of type IV were repaired with bilateral pectoralis muscle flap (n = 65), rectus abdominis muscle flap (n = 5), and pedicled omental flap (n = 8); and wounds of type V were repaired with pedicled omental flap. All the operations were successfully performed. Three patients died after pedicled omental flap repair, including 1 case of type IV and 2 cases of type V. The hospitalization time were 4-86 days (mean, 18.3 days). Primary wound healing was obtained in 248 cases (96.5%); poor healing occurred in 9 patients, which were cured after second surgery in 8 cases and after the third surgery in 1 case. The surgical treatment based on self-generated classification is appropriate to sternal wound complications after cardiac surgery. It can provide clinical evidence for the choice of subsequent operation.

    Full Text Available As immigration to the United States from countries endemic for tuberculosis (TB increases, the incidence of pulmonary and extrapulmonary TB disease may increase. Primary tuberculous sternal osteomyelitis is one form of extrapulmonary TB that is exceedingly rare throughout the world, and falls under the differential diagnosis for chest wall masses. Management involves standard antituberculous therapy with antibiotics similar to treating other forms of extrapulmonary TB, as well as consideration of surgical intervention depending on the extent of osteomyelitis. A typical case of primary sternal TB osteomyelitis is reported, and the epidemiology, differential diagnosis, clinical manifestations and management are reviewed.

    Full Text Available Background. Noncompaction/hypertrabeculation left ventricle (NCM/HVM is most commonly reported in one or more segments of left ventricle and sometimes both ventricles. In this case, we present noncompaction of all segments of right and left ventricle, in a young man with mental retardation. Case Presentation. A 19-year-old male was referred to us with sudden dyspnea at rest and chest discomfort. He was a known case of mental retardation. He was born full term with birth weight = 1250 grams. On physical examination. A systolic murmur (II/VI at left sternal border was heard. ECG showed increased voltage in precordial lead and deep ST segment depression. Chest X-ray (CXR was within normal limits. Transthoracic echocardiography showed situs solitus, D loop, normal connection of great vessels, noncompaction LV at all segments (noncompaction/compaction = 2.5/0.5 with moderate systolic dysfunction (LVEF = 40%, diastolic dysfunction grade II, normal RV size with mild systolic dysfunction and hypertrabeculation, mild tricuspid regurgitation (TR, and normal pulmonary artery systolic pressure. After injection of agitated saline some bubbles were passed from right to left through patent foramen oval (PFO. Conclusions. Extensive sinusoid formation and trabeculation of RV and nearby all LV segments and its association with mental retardation suggest presence of strong genetic background.

    Postoperative deep sternal wound infection is a severe complication of cardiac surgery, with a high mortality rate and a high morbidity rate. The objective of this prospective study is to report our experience with the vacuum assisted closure (VAC) system for the management of deep wound infection. We also devised an innovative closure technique post VAC therapy using thermo reactive clips. The advantage of this technique is that the posterior face of the sternum does not have to be separated from the mediastinal structures thus minimising the risk of damage. From October 2006 to October 2008, we prospectively evaluated 21 patients affected by mediastinitis after sternotomy. Nineteen patients had sternotomy for coronary artery bypass grafting (CABG), one patient for aortic valve replacement (AVR) and another one for ascending aortic replacement (AAR). All patients were treated with the VAC system at the time of infection diagnosis. When the wound tissue appeared viable and the microbiological cultures were negative, the chest was closed using the most suitable procedure for the patient in question; nine patients were closed using pectoralis flaps, nine patients using Nitinol clips, one patient with a combined technique (use of Nitinol clips and muscle flap), one patient with a direct wound closure and another patient, who needed AAR with a homograft performed in another institution, was closed using sternal wires. We had no mortality; wound healing was successfully achieved in all patients. In more than 50% of the patients, the VAC therapy allowed direct sternal resynthesis. The average duration of the vacuum therapy was 26 days (range 14-37 days). VAC is a safe and effective option in the treatment of post-sternotomy mediastinitis, with excellent survival and immediate improvement of local wound conditions; furthermore, the use of Nitinol clips after VAC therapy demonstrated to be a safe and non-invasive option for sternal resynthesis. After VAC therapy, a

    Sternal resection is indicated for a variety of pathological conditions, mainly neoplastic or related to sternotomy complications. Resection of the sternum generally leaves a large chest-wall defect, and reconstruction is thus the most difficult part of the operation. Correct stabilization of the anterior chest wall is very important to avoid secondary complications and respiratory failure. In the last few years, different technical solutions have been used to reconstruct the sternum. We describe our technique using a sternal allograft to reconstruct the anterior chest wall after partial or complete sternal resection. Between June 2010 and February 2012, four patients underwent sternectomy followed by anterior chest wall reconstruction using sternal allograft. The sternal allograft was harvested from a multitissue donor following Italian legislation for tissue donation. Three patients had neoplastic involvement of the sternum, and one had a complete sternal defect as a complication of a cardiac operation. We had no operative mortality. Three patients underwent partial sternal transplantation, and one underwent total sternal replacement. We had no postoperative respiratory insufficiency, infections or mechanical failure of the reconstructions. The respiratory function was preserved in all patients. The follow-up period was free from complications related to the sternal allograft implantation. The technique of sternal allograft transplantation is simple, reproducible and provides excellent functional and cosmetic results. Further studies including a larger number of patients are needed to understand the biology of the allograft and the long-term results of this technique.

    Sternal Wound Infections (SWI) represent a dangerous complication after cardiac surgery entailing significantly longer hospital stays and worse short-term survival, especially in case of deep infections (DSWI) with the onset of osteomielitis or mediastinitis. The real incidence of SWI can be estimated between 0.25% and 10%; among the risk factors for sternal dehiscences after a longitudinal median sternotomy, several experiences underline the role of diabetes as an independent risk factor for post-operative infections, especially in patients affected by COPD with higher BMI. The application of a negative-pressure therapy, through instill modality too, assures a wound cleansing through periodic irrigation of topical solutions with particulate secretion removal; moreover it improves the granulation process owing to the increased blood flow and makes the size wound reduction easier, representing very often the treatment of first-line in DSWI and an optimal bridge for another reconstructive procedure of the sternal defect. The following case report shows how a plastic surgical approach associated to the adoption of a VAC-therapy instill after specific antibiotictherapy has integrated and optimized the trend of a very complex clinical circumstance.

    Abstract We aimed to show the utility and reliability of sternal morphometric analysis for sex estimation. Sex estimation is a very important step in forensic identification. Skeletal surveys are main methods for sex estimation studies. Morphometric analysis of sternum may provide high accuracy rated data in sex discrimination. In this study, morphometric analysis of sternum was evaluated in 1 mm chest computed tomography scans for sex estimation. Four hundred forty 3 subjects (202 female, 241 male, mean age: 44 ± 8.1 [distribution: 30–60 year old]) were included the study. Manubrium length (ML), mesosternum length (2L), Sternebra 1 (S1W), and Sternebra 3 (S3W) width were measured and also sternal index (SI) was calculated. Differences between genders were evaluated by student t-test. Predictive factors of sex were determined by discrimination analysis and receiver operating characteristic (ROC) analysis. Male sternal measurement values are significantly higher than females (P computed tomography analysis of sternum might provide important information for sex estimation. PMID:25501090

    A sternal cleft is an extremely rare developmental anomaly, which results from failure of fusion of sternal bars which contribute to the formation of the sternum. Most cases are diagnosed in early childhood, where it is associated with serious other midline defects. A sternal cleft is seen as a photopenic area on technetium-99m methylene diphosphonate bone scan and can be confused with other conditions. We report an extremely rare case of isolated upper sternal cleft in a 45-years-old male, found incidentally on '9 9m Tc MDP bone scan. (author)

    Border installations cover all nuclear plants located near the border with a neighbouring state. However, the actual distance depends on the context. The distance can vary considerably. Also the prohibition on siting near a heavily populated area also defines the actual distance variably. The distance criteria may be modified by other factors of topography, prevailing climate and so on. Various examples which illustrate the problems are given. For example, the Creys-Melville nuclear power plant is 80km from Geneva and the Cattonam installation is 12km from the French border with Luxembourg and Germany. The Cattenom case is explained and the legal position within the European Institutions is discussed. The French licensing procedures for nuclear power stations are described with special reference to the Cattenom power plant. Border installations are discussed in the context of European Community Law and Public International Law. (U.K.)

    2013-02-01

    Previous work has demonstrated the efficacy of vacuum-assisted closure (VAC) in the treatment of poststernotomy local wound infections, compared to historical treatment protocol. The negative pressure has been found to protect wounds against contamination, prevent wound fluid retention, increase blood flow, and increase rates of granulation tissue formation. For this study, a retrospective analysis compared patients receiving VAC as definitive treatment versus bridging to delayed flap closure. Sixteen patients developed sternal wound infections after cardiac surgeries at the authors' institution from 2006 to 2008. Data was gathered regarding patient comorbidities, treatment method, and outcome. Study objectives included assessment of risk factors that warranted secondary surgicalclosure and examination of long-term followup where VAC was thedefinitive treatment modality. Group A (n = 12) had VAC as the final treatment modality. Group B (n = 4) required myocutaneous flap closure. One patient in Group B passed away prior to flap surgery. Both groups had similar risk factors, except Group B had a higher risk of body mass index (BMI) > 35 that was near statistically significant (P = 0.085; odds ratio = 0.0, 95% CI = [0.0 - 1.21]). Group A required a shorter hospital stay on average. Long-term follow-up showed the majority of Group A had completely healed sternal wounds 2-3 years from initial cardiac surgery. Vacuum-assisted closure as definitive treatment modality is a successful, first line therapy for local superficial sternal wound infections. When deep infections occur, however, VAC as bridge-to-flap coverage is recommended over attempted secondary healing with VAC. .

    Full Text Available Scedosporium is an important pathogen in cystic fibrosis (CF and post-transplant but rarely causes invasive infection. Treatment remains challenging, particularly due to inherent resistance to multiple antifungal agents. We present a young man with CF who developed invasive sternal and rib infection 10-months following lung transplant. The infection has been clinically and radiologically cured with extensive surgery and triazole therapy. This case highlights the importance of adjunctive surgery in addition to prolonged triazole treatment to manage invasive Scedosporium infections in immunosuppressed patients.

    Full Text Available Background: The implementation of seat belt legislation has led to an increase in the frequency of isolated sternal fractures (ISFs in motor vehicle crash. Aims: We reviewed retrospectively the medical records of our tertiary center in order to find out the frequency of ISFs, review our experience in their management, and define the mean length of hospitalization. Materials and Methods: From January 2008 to April 2012, 64 patients were admitted to the accident and emergency department of the University Hospital of Larissa, Greece, suffering from sternal fractures (SFs. Of these 64 patients, 45 had sustained ISF, while the remaining 19 had SF and additional injuries (intrathoracic and extrathoracic. The files of these 45 patients were further investigating as concerning the mechanism of injury, hospitalization days, morbidity, and mortality. Results: All the patients had been involved in motor vehicle crashes and most of them were wearing seat belts during the accident (91%. The hospital length of stay (LOS was 1.85 ± 1.67. All the patients had upon admission chest radiograms, serial electrocardiographs (ECGs, echocardiograms, and cardiac enzyme levels. Two patients had abnormal ECG and abnormal cardiac enzymes which contributed in prolonged hospitalization. However, there was no incidence of cardiac complications or deaths. Conclusions: ISFs, with normal electrocardiogram, cardiac enzymes, and chest X-ray in the absence of complications, require no further investigation.

A retrospective cohort study of adult patients (>16 years with ISF presenting from 2006 to 2010 was conducted. Eighty-eight patients with ISF were identified. Most patients (88%, 77 were admitted to hospital with 66% (58 of them discharged within 48 hours. Two (2% patients had an ER EKG with abnormality but both resolved to normal sinus rhythm within 6 hours of follow-up. Serum CEs were drawn from 55 (63% patients with only 2 (2% having a rise in serum troponin >0.04; however, in both of these patients troponin quickly normalized. Six (7% patients underwent echocardiograms without significant findings. In all 88 patients with ISF, no cases of clinically significant cardiac injury were identified. Patients presenting with an isolated sternal fracture with no changes on EKG or chest X-ray do not warrant an admission to hospital and may be discharged from the ER.

    2014-12-01

    Full Text Available We report the case of an 8-month-old male neonate who underwent reconstructive surgery for a congenital superior sternal cleft to decrease the risk of commotio cordis. With regard to use of the Sally technique for the repair of a relatively wide cleft (4 × 4 cm, we were concerned about respiratory problems caused by compression following closure of the sternal halves. By closing the sternal halves imperfectly, elevation of intrapleural pressure can be avoided to some extent. By bridging the surplus resected cartilage from the lower sternum over the gap of the upper sternum, the heart is protected by more rigid material. We recommend our modified Sally technique because it is both flexible and effective for sternal cleft repair.

    Deep sternal wound infections are significant and severe complications following cardiac surgery and substantially influence perioperative morbidity and mortality. We present the experience of our department using two different surgical treatments over a three-year period. Between January 2009 and December 2011, a total of 3274 cardiac procedures with complete median sternotomy were performed in our department. In 94 patients (3%), a deep sternal wound infection occurred, including sternal instability with consecutive surgical treatment. The patients either received wound debridement with sternum refixation and suction-irrigation drainage (SID; n = 72) or sternum refixation only (RF; n = 22) if there was sternal instability with limited signs of infection. SID was routinely installed for 7 days: the irrigation solution contained neomycin. In all cases, swabs were taken and analysed. The different methods were evaluated in respect of their clinical outcomes. The success rate-defined as single, uncomplicated procedure-of the SID treatment was 74%, compared with 59% of the isolated sternum refixation. Complications included continuous infection, recurrence of sternal instability and wound necrosis. Eighty-eight percent of the swabs in the SID group were positive, compared with 32% in the sternal refixation only group. The dominating pathogenic germs were coagulase-negative staphylococci and staphylococcus aureus. Mortality was 10% for the SID group and 5% for the RF group. Contrary to accepted opinion, the suction-irrigation drainage is an appropriate therapy for deep sternal wound infections. Nevertheless, deep sternal wound infections after cardiac surgery remain severe complications and are related to increased morbidity and mortality.

    Sternal fractures caused by blunt chest trauma are associated with an increased incidence of cardiac injury. Reports of the incidence of cardiac injury associated with sternal fracture range from 18% to 62%. Delayed cardiac tamponade is a rare phenomenon that appears days or weeks after injury. Moreover, after nonpenetrating chest trauma, cardiac tamponade is very rare and occurs in less than 1 of 1000. This case describes a patient who had delayed cardiac tamponade 17 days after a severe blunt chest trauma.

    It is practical value for determination the teenagers whether the age is full of the legal responsibility age of 18 years old or not by estimating skeletal age of sternal end of clavicle. The traditional methods mainly based on X-ray radiography. However, sternal end of clavicle and adjacent lung, bronchus, sternum, rib, transverse process of thoracic vertebra are overlapped each other. As a result of overlapping, there will be obtained false negative or positive film reading results when according to X-ray observation of epiphyseal growth of sternal end of clavicle, which directly affect the scientificalness and accuracy of estimating of skeletal age. In recent years, the scholars at home and abroad have started to use thin layer CT scan technology to estimate skeletal age of the sternal end of clavicle. With the 2D and 3D CT recombination technology, the accuracy of the film reading distinctly improves by making the shape, size and position of epiphysis displayed clearly. This article reviews the application and research progress of thin layer CT scanning technology in estimating skeletal age of sternal end of clavicle at home and abroad, analyzes the superiority and value of thin layer CT scan technology, which applied to skeletal age of sternal end of clavicle.

    Stainless steel wiring remains the most popular technique for primary sternal closure. Recently, a multifilament cable wiring system (Pioneer Surgical Technology Inc., Marquette, MI, USA) was introduced for sternal closure and has gained wide acceptance due to its superior resistance to tension. We aimed to compare conventional steel wiring to multifilament cable fixation for sternal closure in patients undergoing major cardiac surgery. Data were collected retrospectively on 1,354 patients who underwent sternal closure after major cardiac surgery, using either the multifilament cable wiring system or conventional steel wires between January 2009 and October 2010. The surgical outcomes of these two groups of patients were compared using propensity score matching based on 18 baseline patient characteristics. Propensity score matching yielded 392 pairs of patients in the two groups whose baseline profiles showed no significant differences. No significant differences between the two groups were observed in the rates of early mortality (2.0% vs. 1.3%, p=0.578), major wound complications requiring reconstruction (1.3% vs. 1.3%, p>0.99), minor wound complications (3.6% vs. 2.0%, p=0.279), or mediastinitis (0.8% vs. 1.0%, p=1.00). Patients in the multifilament cable group had fewer sternal bleeding events than those in the conventional wire group, but this tendency was not statistically significant (4.3% vs. 7.4%, p=0.068). The surgical outcomes of sternal closure using multifilament cable wires were comparable to those observed when conventional steel wires were used. Therefore, the multifilament cable wiring system may be considered a viable option for sternal closure in patients undergoing major cardiac surgery.

    This chapter highlights the legal problems raised by the concept of a border installation. Using the Cattenom nuclear power plant as an example, the author describes the different stages of the legal conflict raised by construction of the plant and analyses the relationship between French administrative law and some provisions of the Euratom Treaty. Based on the Treaty, the Community institutions have adopted directives to strengthen inter-State co-operation and consultation between neighbouring countries. He observes that these principles of co-operation, consultation and vigilance already exist in public international law; however, international case law has not yet made it possible to establish the strict liability of the constructing state in case of a nuclear accident (NEA) [fr

    Full Text Available Abstract Background Infective Endocarditis (IE is considered as a multifaceted problem in every aspect from etiology and presentation to diagnosis and management. Early recognition of this disease and especially its complications, remain a critical task for the cardiologist. Atrial endocarditis is a rare and sometimes unrecognized complication of mitral valve endocarditis. Case presentation We present a 48 year-old male patient who was admitted to our clinic because of recent onset of malaise, fever, jaundice and peripheral edema. Important physical findings were peripheral stigmata of IE in addition to holosystolic murmur over the left sternal border. Transthoracic and transesophageal echocardiophy revealed a severe eccentric MR due to a flailed posterior mitral valve caused by IE. The presence of atrial septal endocarditis caused by jet streaming was also observed. Blood culture was positive for streptococcus oralis and antibiotic therapy was immediately initiated. Considering the large burden of infective tissue, the patient was planned for an early surgical intervention. A minimally invasive resection of the atrial mass, direct closure of the defect, resection of the diseased portions of mitral leaflets and implantation of a biological mitral valve prosthesis was performed. Intra-operative and histological findings confirmed provisional diagnosis by echocardiography. Conclusions Together with comprehensive echocardiographic evaluation, attention should be placed on mural vegetations and excluded among all cases of mitral valve endocarditis, particularly those with severe eccentric regurgitant jets.

    Full Text Available Abstract Background Deep sternal wound infection after cardiac surgery carries high morbidity and mortality. Our strategy for deep sternal wound infection is aggressive strenal debridement followed by vacuum-assisted closure (VAC therapy and omental-muscle flap reconstrucion. We describe this strategy and examine the outcome and long-term quality of life (QOL it achieves. Methods We retrospectively examined 16 patients treated for deep sternal wound infection between 2001 and 2007. The most recent nine patients were treated with total sternal resection followed by VAC therapy and secondary closure with omental-muscle flap reconstruction (recent group; whereas the former seven patients were treated with sternal preservation if possible, without VAC therapy, and four of these patients underwent primary closure (former group. We assessed long-term quality of life after DSWI by using the Short Form 36-Item Health Survey, Version 2 (SF36v2. Results One patient died and four required further surgery for recurrence of deep sternal wound infection in the former group. The duration of treatment for deep sternal wound infection in the recent group was significantly shorter than that in previous group (63.4 ± 54.1 days vs. 120.0 ± 31.8 days, respectively; p = 0.039. Despite aggressive sternal resection, the QOL of patients treated for DSWI was only minimally compromised compared with age-, sex-, surgical procedures-matched patients without deep sternal wound infection. Conclusions Aggressive sternal debridement followed by VAC therapy and secondary closure with an omental-muscle flap is effective for deep sternal wound infection. In this series, it resulted in a lower incidence of recurrent infection, shorter hospitalization, and it did not compromise long-term QOL greatly.

    We present a case of a 20-year-old female in whom we successfully performed a simultaneous Bentall procedure and thoracoplasty by initially removing only the left side of the costal cartilages. This modified sternal elevation technique offered chest stability and an excellent surgical view, and the postoperative course was satisfactory.

    Rigid sternal fixation (RSF) has been shown to reduce sternal wound complications in high-risk patients. However, the higher initial cost continues to deter its use. This study evaluates the cost of caring for high-risk sternotomy patients who underwent RSF compared with those who underwent sternal closure with a modified wire technique (MWT). A retrospective single institution review of high-risk patients who underwent MWT (n = 45) and RSF (n = 30) for primary sternal closure from 2006 to 2009 was conducted. Total hospital cost, revenue, and net cost associated with surgery and subsequent care were analyzed. Overall rates of wound dehiscence and wound infections (superficial and deep) were higher in MWT patients (n = 14, 13, and 7, respectively) than RSF patients (n = 3, 2, and 0, respectively; P costs associated with their operative hospitalization, outpatient care, and home health than RSF patients (total net loss: US $41,436 ± 7327 vs US $10,612 ± 4,258; P = 0.034). In high-risk patients, RSF is associated with lower rates of infections, including the "never event" mediastinitis, compared with MWT. Moreover, despite the initial higher cost, RSF affords an overall lower cost of care compared with MWT in patients at high-risk for developing sternal complications.

    Sternal resection is occasionally required for patients with malignant tumors, particularly sarcomas, in the sternal region. Few reports have described post-operative respiratory and shoulder function after sternal resection for patients with bone and soft-tissue sarcomas. Eight consecutive patients with bone and soft tissue sarcomas requiring sternal resection were the focus of this study. Chest wall was reconstructed with a non-rigid or semi-rigid prosthesis combined, in most cases, with soft tissue flap reconstruction. Clinical outcomes investigated included complications, shoulder function, evaluated with Musculoskeletal Tumor Society-International Symposium of Limb Salvage system, and respiratory function, evaluated by use of spirometry. The anterior chest wall was reconstructed with non-rigid strings for 3 patients and with polypropylene mesh for 5. There were no severe post-operative complications, for example surgical site infection or pneumonia. All 3 patients with non-rigid reconstruction experienced paradoxical breathing, whereas none with polypropylene mesh did so. Post-operatively, FEV(1)% was unchanged but %VC was significantly reduced (p = 0.01), irrespective of the reconstruction method used (strings or polypropylene mesh). Shoulder function was not impaired. Among patients undergoing sternal resection, post-operative shoulder function was excellent. Pulmonary function was slightly restricted, but not sufficiently so to interfere with the activities of daily living (ADL). Paradoxical breathing is a slight concern for non-rigid reconstruction.

    Sternal wound infection is still one of the critical and challenging complications after cardiac surgery. Vacuum-assisted closure (VAC) therapy is a unique and simple system that helps promote wound healing. We report 3 cases with the sternal wound infection after cardiac surgery, in which VAC therapy was applied between January, 2005 and April, 2007. Two of them had good response to VAC therapy and had their wound healed after 3 and 5 weeks, respectively. However, the remaining case, in which bilateral internal thoracic artery had been taken down for coronary artery bypass grafting (CABG) and osteomyelitis of the sternum was not well controlled, did not respond to VAC therapy. Our results suggested that VAC might facilitate wound healing of the patients with sternal wound infection only after abscess was drained and opened, while it might not be useful for the patents with osteomyelitis.

    A surgical incision for bilateral sequential lung transplantation (BSLTX) is the "clam shell" (CSI) approach via bilateral anterior thoracotomies and a transverse sternotomy to allow for sequential replacement of the lungs. This can be associated with significant post-operative pain, bony overriding or sternal instability. The sternal instability scale (SIS) is a non-invasive manual assessment tool that can be used to detect early bony non-union or instability following CSI; however, its reliability is unknown. This prospective blinded reliability study aimed to assess intra-rater and inter-rater reliability of the SIS following lung transplantation. Participants post BSLTX aged older than 18 years underwent sternal assessment utilizing the SIS. Two assessors examined the sternum using a standardized protocol at two separate time points with a test-re-test time of 48 hours. The outcome measure was SIS tool using four categories from 0 (clinically stable) to 3 (separated sternum with overriding). In total, 20 participants (75% female) with a mean age of 48 years (SD 17) and mean pain score of 3 out of 10 were included, 60% having well healed wounds and 25% reporting symptoms of sternal clicking. The most painful self-reported painful activity was coughing. The SIS demonstrated excellent reliability with a kappa = 0.91 by different assessors on the same day, and kappa = 0.83 for assessments by the same assessor on different days. The SIS is a reliable manual assessment tool for evaluation of sternal instability after CSI following BSLTX and may facilitate the timely detection and management of sternal instability.

    Vacuum-assisted closure (VAC) was primarily designed for the treatment of pressure ulcers or chronic, debilitating wounds. Recently, VAC has become an encouraging treatment modality for sternal wound infection after cardiac surgery, providing superior results to conventional treatment strategies. From November 2004 to September 2006, 34 patients, undergoing VAC therapy for sternal wound infection following cardiac surgery, were prospectively evaluated. Ten patients (29 %) were treated for superficial sternal wound infection and 24 (71 %) for deep sternal wound infection. The median age was 69.9 years (range 48 to 82) and the median BMI was 33.4 kg/m(2) (range 28 to 41). Twenty patients (59 %) were women and 19 patients (59 %) were diabetics. Owing to sternal wound infection complications, 16 patients (47 %) were readmitted to the department. VAC was used following the previous failure of the conventional treatment strategy in 7 patients (21 %). Thirty-three patients (97 %) were treated successfully. One patient (3 %) died of multiple organ failure. The overall length of hospitalization was 34.6 days (range 9 to 62). The median number of dressing changes was 4.6 (range 3 to 10). The median VAC treatment time until surgical closure was 9.2 days (range 6 to 21 days). VAC therapy was solely used as a bridge to definite wound closure. Three patients (9 %) with chronic fistula were re-admitted 1 to 6 months after VAC therapy. VAC therapy is a safe and reliable option in the treatment of sternal wound infection in cardiac surgery. VAC therapy should be considered an effective adjunct to conventional treatment modalities for the treatment of extensive and life-threatening wound infections following cardiac surgery, particularly in the presence of risk factors.

    This study investigated the relationship between the peak sternal deflection measurements recorded by the Hybrid III 50th percentile male anthropometric test device (ATD) in frontal crash tests and injury and fatality outcomes for drivers in field crashes. ATD sternal deflection data were obtained from the Insurance Institute for Highway Safety's 64 km/h, 40 percent overlap crashworthiness evaluation tests for vehicles with seat belt crash tensioners, load limiters, and good-rated structure. The National Automotive Sampling System Crashworthiness Data System (NASS-CDS) was queried for frontal crashes of these vehicles in which the driver was restrained by a seat belt and air bag. Injury probability curves were calculated by frontal crash type using the injuries coded in NASS-CDS and peak ATD sternal deflection data. Fatality Analysis Reporting System (FARS) front-to-front crashes with exactly one driver death were also studied to determine whether the difference in measured sternal deflections for the 2 vehicles was related to the odds of fatality. For center impacts, moderate overlaps, and large overlaps in NASS-CDS, the probability of the driver sustaining an Abbreviated Injury Scale (AIS) score ≥ 3 thoracic injury, or any nonextremity AIS ≥ 3 injury, increased with increasing ATD sternal deflection measured in crash tests. For small overlaps, however, these probabilities decreased with increasing deflection. For FARS crashes, the fatally injured driver more often was in the vehicle with the lower measured deflection in crash tests (55 vs. 45%). After controlling for other factors, a 5-mm difference in measured sternal deflections between the 2 vehicles was associated with a fatality odds ratio of 0.762 for the driver in the vehicle with the greater deflection (95% confidence interval = 0.373, 1.449). Restraint systems that reduce peak Hybrid III sternal deflection in a moderate overlap crash test are beneficial in real-world crashes with similar or greater

     Primary sternal chondrosarcoma is a rare malignant tumor that is refractory to chemotherapy and radiation. Effective therapy is radical resection of the tumor. We present two patients with primary sternal chondrosarcoma who underwent a radical resection of the lower half of the sternum and bilateral ribs, followed by reconstruction with 2 sheets of polypropylene mesh layered orthogonally. The patients have maintained almost the same pulmonary function as preoperative values, with stability of the chest wall. Although there are various ways to reconstruct the anterior chest wall, reconstruction with polypropylene mesh layered orthogonally is an easy-to-use and sufficient method.

    Intraosseous vascular infusion (IO) is a recognized alternative to peripheral intravenous infusion when access is inadequate. The sternum and proximal tibia are the preferred sites. A review of 98 cases at autopsy revealed successful sternal IO placement in 78 cases (80%). Assuming a worst case scenario for placement (pin mark and no tip in bone [17 cases] and tip present and not in the sternum [3 cases]), attempts were unsuccessful in 20 cases (20%). We draw no specific conclusions regarding sternal IO use, but hope that personnel placing these devices and those providing medical training can use the information. 2011.

    Full Text Available Introduction: Mediastinitis is a devastating complication in open heart surgery. The most common treatments after debridement are rewiring with antibiotic irrigation. Vacuum assisted closure therapy is a recently introduced technique that promotes the healing of difficult wounds, including post-sternotomy mediastinitis.Patients and Methods: Forty one patients with deep sternal wound infection were divided into two groups based on the treatment method used. Twenty two patients with post-cardio to my deep sternal wound infection were treated primarily by vacuum assisted closure method (group A and 19 patients with deep sternal wound infection who received closed mediastinal irrigation were treated with antibiotics (group B between January 2006 and January 2010.Results: The two groups were compared. Three patients died during treatment in group B. The median healing time was significantly shorter in group A (mean, 13.5 ± 3.2 days compared to 18 days (mean, 21.2 ± 16.4 days in group B (p< 0.001. Deep sternal wound infection showed no recurrences after the vacuum treatment, while 7 (24% patients in group B suffered recurrences.

    Full Text Available Autologous and nonautologous bone marrow mesenchymal stem/stromal cells (MSCs are being evaluated as proangiogenic agents for ischemic and vascular disease in adults but not in children. A significant number of newborns and infants with critical congenital heart disease who undergo cardiac surgery already have or are at risk of developing conditions related to inadequate tissue perfusion. During neonatal cardiac surgery, a small amount of sternal tissue is usually discarded. Here we demonstrate that MSCs can be isolated from human neonatal sternal tissue using a nonenzymatic explant culture method. Neonatal sternal bone MSCs (sbMSCs were clonogenic, had a surface marker expression profile that was characteristic of bone marrow MSCs, were multipotent, and expressed pluripotency-related genes at low levels. Neonatal sbMSCs also demonstrated in vitro proangiogenic properties. Sternal bone MSCs cooperated with human umbilical vein endothelial cells (HUVECs to form 3D networks and tubes in vitro. Conditioned media from sbMSCs cultured in hypoxia also promoted HUVEC survival and migration. Given the neonatal source, ease of isolation, and proangiogenic properties, sbMSCs may have relevance to therapeutic applications.

    Sternal fractures occur infrequently with blunt force trauma. The demographics and epidemiology of associated injuries have not been well characterized from a national trauma database. The National Trauma Data Bank was queried for patients with closed sternal fractures. The demographics were analyzed by age, gender, mechanism and indicators of anatomic and physiologic injuries. Types of commonly associated injuries were also determined. A total of 23,985 records were analyzed. Males accounted for 68.3 per cent and whites 70.9 per cent. Motor vehicle crash was the leading mechanism. More than 56 per cent had severe injuries based on Injury Severity Score (greater than 15) and 17 per cent with Glasgow Coma Score 8 or less. Crude mortality was 7.9 per cent. The majority (57.8%) and approximately one-third (33.7%) of the patients had rib fractures and lung contusions, respectively, 22.0 per cent with closed pneumothorax, 21.6 per cent had a closed thoracic vertebra fracture, 16.9 per cent with lumbar spine fracture, 3.9 per cent with concussion, and blunt cardiac injury in 3.6 per cent. Sternal fractures are usually associated with severe blunt trauma. Lung contusion remains the leading associated injury followed by vertebral spine fractures. Cardiac injuries are less frequent and vascular injuries less so. Mechanism of injury and presence of sternal fractures should alert providers to these potential associated injuries.

    Deep sternal wound infection is a life-threatening complication after cardiac surgery. The aim of this study was to investigate the factors leading to mortality, and to explore wound management techniques on deep sternal wound infection after coronary artery bypass surgery. Between 2008 and 2013, 58 patients with deep sternal wound infection were analyzed. Risk factors for mortality and morbidity including age, gender, body mass index, smoking status, chronic renal failure, hypertension, diabetes, and treatment choice were investigated. In this study, 19 patients (32.7%) were treated by primary surgical closure (PSC), and 39 patients (67.3%) were treated by delayed surgical closure following a vacuum-assisted closure system (VAC). Preoperative patient characteristics were similar between the groups. Fourteen patients (24.1%) died in the postoperative first month. The mortality rate and mean duration of hospitalization in the PSC group was higher than in the VAC group (P = .026, P = .034). Significant risk factors for mortality were additional operation, diabetes mellitus, and a high level of EuroSCORE. Delayed surgical closure following VAC therapy may be associated with shorter hospitalization and lower mortality in patients with deep sternal wound infection. Additional operation, diabetes mellitus, and a high level of EuroSCORE were associated with mortality.

    Surgical site infection is a common complication following cardiac surgery. Triclosan-coated sutures have been shown to reduce the rate of infections in various surgical wounds, including wounds after vein harvesting in coronary artery bypass grafting patients. Our purpose was to compare the rate of infections in sternotomy wounds closed with triclosan-coated or conventional sutures. A total of 357 patients that underwent coronary artery bypass grafting were included in a prospective randomized double-blind single-center study. The patients were randomized to closure of the sternal wound with either triclosan-coated sutures (Vicryl Plus and Monocryl Plus, Ethicon, Inc., Somerville, NJ, USA) (n = 179) or identical sutures without triclosan (n = 178). Patients were followed up after 30 days (clinical visit) and 60 days (telephone interview). The primary endpoint was the prevalence of sternal wound infection according to the Centers for Disease Control and Prevention (CDC) criteria. The demographics in both groups were comparable, including age, gender, body mass index, and rate of diabetes and smoking. Sternal wound infection was diagnosed in 43 patients; 23 (12.8%) sutured with triclosan-coated sutures compared to 20 (11.2%) sutured without triclosan (p = 0.640). Most infections were superficial (n = 36, 10.1%), while 7 (2.0%) were deep sternal wound infections. There were 16 positive cultures in the triclosan group and 17 in the non-coated suture group (p = 0.842). The most commonly identified main pathogens were Staphylococcus aureus (45.4%) and coagulase-negative staphylococci (36.4%). Skin closure with triclosan-coated sutures did not reduce the rate of sternal wound infection after coronary artery bypass grafting. (clinicaltrials.gov: NCT01212315).

    To measure hot flashes by sternal skin conductance in an urban Mexican population and to determine variables associated with hot flash reporting and measurement. From June 1999 to August 2000, 67 perimenopausal women aged 40 to 65 years participated in interviews, anthropometric measures, and a 2-h recording of sternal skin conductance. Changes in sweating were used to demonstrate the presence/absence of a hot flash. During the test, women were asked to report if they experienced a hot flash. During the study period, 10 women reported and demonstrated every hot flash, 24 women never reported or demonstrated a hot flash, 7 demonstrated hot flashes but did not report any of them, 7 reported hot flashes but did not demonstrate any of them, and 19 showed a mixture of responses. Women who demonstrated hot flashes by sternal skin conductance were measured in a warmer room, had more years of education, consumed more eggs as a child, recalled a heavier weight at age 18, and had a lower body mass index at interview compared with women who did not demonstrate hot flashes by sternal skin conductance. Women who subjectively reported hot flashes were measured in a warmer room, were more likely to be postmenopausal, reported more frequent consumption of coffee, and spent fewer months breast-feeding their last child compared with women who did not report the experience of hot flashes during the testing period. Room temperature explained part of the variation between women who did and did not demonstrate hot flashes via sternal skin conductance, between women who did and did not report the experience of hot flashes, and between women who did and did not demonstrate concordance in objective and subjective measures. In addition to room temperature, coffee intake, months spent breast-feeding the last child, and recalled weight at age 18 were important variables predicting hot flash experience.

    This systematic review and meta-analysis was performed to determine whether timing or type of tracheostomy was associated with superficial or deep sternal wound infections after cardiac surgery. All studies reporting the incidence of sternal wound infection after tracheostomy in patients undergoing cardiac surgery were collected and analyzed. Subgroup analyses determined a priori included timing of tracheostomy and type of procedure (open vs percutaneous). All analyses used the random effects model. A meta-regression analysis was performed on the proportion of sternal wound infection and number of days between tracheostomy and initial cardiac surgery. A total of 13 studies met inclusion criteria. The incidence of sternal wound infection across all studies reported was 7% (95% confidence interval [CI], 4-10). The percutaneous tracheostomy group had a sternal wound infection proportion of 3% (95% CI, 1-8), and the open tracheostomy group had a sternal wound infection proportion of 9% (95% CI, 5-14). The incidence of sternal wound infection with early (<14 days) (7%; 95% CI, 3-11) versus late (≥14 days) (7%; 95% CI, 4-10) tracheostomy was similar. Meta-regression demonstrated no significant relationship between incidence of sternal wound infection and number of days between tracheostomy and initial cardiac surgery (R 2  = 6.13%, P = .72). Reported secondary outcomes included 30-day and 1-year mortality, which were high at 23% (95% CI, 19-28) and 63% (95% CI, 43-80), respectively. The incidence of sternal wound infection after tracheostomy in patients undergoing cardiac surgery remains high at 7% (95% CI, 4-10). Open or percutaneous tracheostomy after cardiac surgery is a feasible option because the incidence of sternal wound infection and short-term mortality are comparable. Moreover, the timing of tracheostomy (early or late) had comparable rates of sternal wound infection and short-term mortality. Copyright © 2016 The American Association for Thoracic

    Reinforcement of chest closure may be required in patients with multiple risk factors of wound dehiscence. Performance of a light, size-adaptable closure reinforcement device (DSS: Sternal Synthesis Device; Mikai SpA, Vicenza, Italy) is presented. A longitudinal median or paramedian incision was performed in artificial sternal models: closure was accomplished with simple interrupted steel wires or reinforced with the DSS. Forces required for separation of the rewired sternal halves during a monotonic tensile test were analyzed. A high velocity traction cycles test was also adopted to simulate the impact of coughing. After median incision, ultimate load values inducing break of the sternum models were 580 +/- 35 N (Newton) in controls; failure of the test occurred at 1,200 +/- 47 N in the reinforced group (p = 0.0002). More lateral displacement of sternal halves at increasing forces was observed in controls (p = 0.0001). After paramedian incision, ultimate load values inducing break of the constructs were lower in controls (220 +/- 20 N vs 500 +/- 25 N, p = 0.001), which also showed more lateral displacement of sternal halves than the reinforced group (p = 0.002). At the high velocity traction cycles test, the number of cycles required to break the models was lower in controls (2,250 +/- 35 vs 3,855 +/- 48 cycles, p = 0.0001). Preliminary clinical experience in 45 patients showed ease of implantation and low risk of complications. The proposed sternal reinforcement device provides substantial sternal support at electromechanical testing after median and faulty sternotomy and may hopefully prevent sternal wires migration and bone fractures in high risk patients.

    Full Text Available The interplay between the pectoral module (the pectoral girdle and limbs and the pelvic module (the pelvic girdle and limbs plays a key role in shaping avian evolution, but prior empirical studies on trait covariation between the two modules are limited. Here we empirically test whether (size-corrected sternal keel length and ilium length are correlated during avian evolution using phylogenetic comparative methods. Our analyses on extant birds and Mesozoic birds both recover a significantly positive correlation. The results provide new evidence regarding the integration between the pelvic and pectoral modules. The correlated evolution of sternal keel length and ilium length may serve as a mechanism to cope with the effect on performance caused by a tradeoff in muscle mass between the pectoral and pelvic modules, via changing moment arms of muscles that function in flight and in terrestrial locomotion.

    Full Text Available A 15-year-old boy was referred to our hospital for further investigation and treatment of sternal osteomyelitis due to blunt chest trauma, more specifically elbowing during a basketball game 19 days earlier. On an initial presentation, his chest was markedly swollen and chest computed tomography demonstrated a sternal fracture and massive fluid collection in the chest wall. Since his general condition remained fairly good, we initially selected minimal drainage concomitant with antibiotics; if it was unsuccessful, we planned to switch to a more radical debridement procedure. The patient recovered without further invasive intervention and was discharged on postoperative day 26. There is no sign of recurrence six months after operation. This case report indicates that minimal drainage would be a good option for treatment in a phased strategy.

    Traditionally, measurements of the oxygen saturation (SpO2) has been confound to the extremities. In this study, we therefore investigated the possibility for reliable estimation of clinically relevant SpO2 levels from photoplethysmography (PPG) obtained on the sternum of patients with obstructive...... airway diseases. We initiated the study with a calibration of a prototype sternal PPG sensor. In accordance with the ISO 80601-2-61:2011 guidelines, the calibration was conducted as a controlled desaturation study. We obtained a calibration accuracy of 1.75% which is well within the clinically...... and commercially accepted range. We then compared the SpO2 levels simultaneously obtained from the sternal PPGs and a commercially available finger pulse oximeter on 28 admitted patients with either asthma or Chronic Obstructive Pulmonary Disease (COPD). The Pearson correlation between the SpO2 levels estimated...

    The midline pattern of sternal ossification characteristic of the Cretaceous enantiornithine birds is unique among the Ornithodira, the group containing birds, nonavian dinosaurs and pterosaurs. This has been suggested to indicate that Enantiornithes is not the sister group of Ornithuromorpha, the clade that includes living birds and their close relatives, which would imply rampant convergence in many nonsternal features between enantiornithines and ornithuromorphs. However, detailed comparisons reveal greater similarity between neornithine (i.e. crown group bird) and enantiornithine modes of sternal ossification than previously recognized. Furthermore, a new subadult enantiornithine specimen demonstrates that sternal ossification followed a more typically ornithodiran pattern in basal members of the clade. This new specimen, referable to the Pengornithidae, indicates that the unique ossification pattern observed in other juvenile enantiornithines is derived within Enantiornithes. A similar but clearly distinct pattern appears to have evolved in parallel in the ornithuromorph lineage. The atypical mode of sternal ossification in some derived enantiornithines should be regarded as an autapomorphic condition rather than an indication that enantiornithines are not close relatives of ornithuromorphs. Based on what is known about molecular mechanisms for morphogenesis and the possible selective advantages, the parallel shifts to midline ossification that took place in derived enantiornithines and living neognathous birds appear to have been related to the development of a large ventral keel, which is only present in ornithuromorphs and enantiornithines. Midline ossification can serve to medially reinforce the sternum at a relatively early ontogenetic stage, which would have been especially beneficial during the protracted development of the superprecocial Cretaceous enantiornithines.

    Full Text Available Introduction. Sternal fractures often occur together with serious and life-threatening additional injuries. This retrospective study was designed to assess concomitant injuries and develop a correlation between fracture location and the severity of injury. Methods. All patients ( diagnosed with a fracture of the sternum by means of a CT scan were analysed with respect to accident circumstances, fracture morphology and topography, associated injuries, and outcome. Results. Isolated sternal fractures occurred in 9%. In all other admissions, concomitant injuries were diagnosed: mainly rip fractures (64%, injury to the head (48%, the thoracic spine (38%, lumbar spine (27%, and cervical spine (22%. Predominant fracture location was the manubrium sterni. In these locations, the observed mean ISS was the highest. They were strongly associated with thoracic spine and other chest injuries. Furthermore, the incidence of head injuries was significantly higher. ICU admission was significantly higher in patients with manubrium sterni fractures. Conclusion. Sternal fractures are frequently associated with other injuries. It appears that the fracture location can provide important information regarding concomitant injuries. In particular, in fractures of manubrium sterni, the need for further detailed clinical and radiologic workup is necessary to detect the frequently associated injuries and reduce the increased mortality.

    This study was undertaken to examine the outcome of patients with deep sternal wound infection (DSWI) now treated with vacuum-assisted closure (VAC) therapy as a bridge to sternal osteosynthesis with horizontal titanium plate fixation. From 1992 to 2007, a consecutive cohort of 23,499 patients underwent open-heart surgery (OHS) in our institution. The period under study was divided in two according to the use of therapeutic modalities: conventional (1992-2001, N=118 DSWI): debridement/drainage with primary closure and irrigation (N=37), debridement/drainage, open packing followed by pectoralis myocutaneous flaps (PMFs) (N=81); contemporary (2002-2007, N=149 DSWI): conventional treatment (N=24) and VAC therapy (N=125/83.8%). VAC was followed by sternal osteosynthesis with horizontal titanium plates in 92 patients (61.7%). DSWI was diagnosed in 267 out of 23 499 (1.1%) patients of our entire series according to Center for Disease Control - Atlanta (CDC) criteria, 118 out of 13 180 (0.9%) in the first and 149 out of 10 319 (1.4%) in the second period (p=0.001). Hospital mortality (N=267/23,499) has been 10.25% for the entire cohort under study without any difference between groups (1992-2001: 11.4%; 2002-2007: 9.1%, p=0.67). More recently, VAC therapy (N=125) was associated with a lower mortality (4.8% vs 14.1%, p=0.01). Stepwise multivariable logistic regression analysis for both periods revealed that prolonged intubation in the intensive care unit (ICU), use of bilateral internal thoracic artery grafting (BIMA), diabetes, re-operation for bleeding and body mass index (BMI) >30 kgm(-2) are the most powerful predictors of DSWI. In the more recently treated patients using VAC therapy, combined procedures (valve and graft) also emerged as a significant predictor. For the entire study, Staphylococcus epidermidis (49.6%) has been the most frequently identified pathogen, followed by Staphylococcus aureus (38.8%). Methicillin-resistant S.aureus (MRSA) was observed in 4

    Full Text Available Background: This study aimed to investigate sternal healing over time and the incidence of poor sternal healing in patients undergoing coronary artery bypass graft (CABG surgery using bilateral internal thoracic arteries. Methods: This study enrolled 197 patients who underwent isolated CABG using skeletonized bilateral internal thoracic arteries (sBITA from 2006 through 2009. Postoperative computed tomography (CT angiography was performed on all patients at monthly intervals for three to six months after surgery. In 108 patients, an additional CT study was performed 24 to 48 months after surgery. The axial CT images were used to score sternal fusion at the manubrium, the upper sternum, and the lower sternum. These scores were added to evaluate overall healing: a score of 0 to 1 reflected poor healing, a score of 2 to 4 was defined as fair healing, and a score of 5 to 6 indicated complete healing. Medical records were also retrospectively reviewed to identify perioperative variables associated with poor early sternal healing. Results: Three to six months after surgery, the average total score of sternal healing was 2.07±1.52 and 68 patients (34.5% showed poor healing. Poor healing was most frequently found in the manubrium, which was scored as zero in 72.6% of patients. In multivariate analysis, the factors associated with poor early healing were shorter post-surgery time, older age, diabetes mellitus, and postoperative renal dysfunction. In later CT images, the average sternal healing score improved to 5.88±0.38 and complete healing was observed in 98.2% of patients. Conclusion: Complete sternal healing takes more than three months after a median sternotomy for CABG using sBITA. Healing is most delayed in the manubrium.

    Full Text Available Abstract Background Wire closure still remains the preferred technique despite reasonable disadvantages. Associated complications, such as infection and sternal instability, cause time- and cost-consuming therapies. We present a new tool for sternal closure with its first clinical experience and results. Methods The sternal ZipFixTM System is based on the cable-tie principle. It primarily consists of biocompatible Poly-Ether-Ether-Ketone implants and is predominantly used peristernally through the intercostal space. The system provides a large implant-to-bone contact for better force distribution and for avoiding bone cut through. Results 50 patients were closed with the ZipFixTM system. No sternal instability was observed at 30 days. Two patients developed a mediastinitis that necessitated the removal of the device; however, the ZipFixTM were intact and the sternum remained stable. Conclusions In our initial evaluation, the short-term results have shown that the sternal ZipFixTM can be used safely and effectively. It is fast, easy to use and serves as a potential alternative for traditional wire closure.

    Deep sternal wound infection (DSWI) is a devastating complication that increases morbidity and death in cardiac surgical patients. Vancomycin is often administered intravenously for antibiotic prophylaxis in cardiac operations. Many cardiac surgeons also apply vancomycin paste topically to the sternal edges. We examined the effect of vancomycin paste on the incidence of DSWI in patients undergoing elective cardiac operations. We retrospectively reviewed the medical records of all patients from 2003 to 2015 who underwent coronary artery bypass grafting, valve, or combined coronary artery bypass grafting and valve operations at a single institution. We derived The Society for Thoracic Surgeons (STS) DSWI risk index for each patient and systematically reviewed operative, pharmacy, microbiology, and discharge records to document DSWI in these patients. Multivariate analyses were used to identify predictors of DSWI in this cohort and to quantify the effect of vancomycin paste. Of the 14,492 patients whose records we examined, DSWI developed in 136 patients, resulting in an overall incidence of 0.9%. After multivariate analysis, body mass index, New York Heart Association Functional Classification, and the STS DSWI risk index remained statistically significant and associated with DSWI. Although the incidence of DSWI decreased over time, the use of vancomycin paste was not associated with a reduced incidence of DSWI. There was a marked decrease in the incidence of DSWI during the study period, concurrent with institutional implementation of revised STS antibiotic dosing guidelines in 2007 and other strategies. However, the application of vancomycin paste to the sternal edges of patients undergoing cardiac operations was not associated with a reduced risk of DSWI.

    The sternal foramen (SF) constitutes a specific anatomic defect in sternum, indicating an impaired fusion of ossificated segments, which occurs either in an anatomical part of the sternum or in sternal joints. The aim of this article is to provide baseline statistical data about the variations of the SF, to present a short review of the relevant literature and to compare results with other studies and populations. We review relevant literature, and we present data obtai-ned from skeletal samples of known population and sex. A total of 35 well-preserved dried sterna from the prefecture of Eastern Macedonia and Thrace, Greece, were selected: 20 men and 15 women with a mean age of 55 ± 6 years old. Measurements were made with a sliding calliper and photographic documentation. The incidence of the SF in the 35 dried specimens was 14.2%, 4 men (20% of male sample) and 1 woman (6.6% of female sample) and 80% of sternal foramina were observed in male individuals. The SF was found in the sternum body (2 cases, 40% of foramina), in xiphoid process (2 cases, 40% of foramina) and in sternoxiphoidal junction (1 case, 20% of foramina). All of the sterna presented 1 single visible SF. Two anatomically unique cases were identified throughout these 5 sterna, both belonging in male subjects. The SF constitutes a relatively common variation with great radiological, clinical, and forensic significance. Presence of a SF with irregular bony margins complicates considerably radiological differential diagnosis. Awareness of this important anatomic variation is fundamental for clinicians and autopsy pathologists, in order to avoid severe fatal complications and elucidate the exact cause of death, respectively.

    An unstable anterior or posterior sternoclavicular joint dislocation can cause severe morbidity with poor shoulder movement and strength. These dislocations need to be repaired, which can be challenging. Many different procedures have been described to obtain a stable joint fixation with varying results. We report a new technique for repairing a sternoclavicular joint dislocation by using a figure-of-eight sternal cable system. This procedure is relatively simple and reproducible to create a stable and functional sternoclavicular joint. Copyright © 2013 The Society of Thoracic Surgeons. Published by Elsevier Inc.

    SAPHO syndrome-acronym for synovitis, acne, pustules, hyperostosis and osteitis, is a nosological entity including multiple affections with cutaneous and osteoarticular involvement. We report the case of a 59 years old female patient that consulted due to an acute sternal pain. After some months the patient showed a palm-plantar pustular exanthem, acne and fever. SAPHO syndrome was diagnosed based on a CT, an osseous gammagraphy and a biopsy of cutaneous lesions. The current actual tendency is to consider the SAPHO syndrome as a seronegative arthropathy with a similar pathophysiology to Reiter's syndrome. (author)

    Two acute and subchronic oral toxicity studies were conducted in rats to evaluate safety of a patented preparation of hydrolyzed chicken sternal cartilage (BioCell Collagen II) containing collagen type II, chondroitin sulfate, and hyaluronic acid. In the acute oral toxicity study, five males and five females of Sprague-Dawley rats were administered a single dose of 5000 mg of the test product per kg body weight and observed for 14 days. All animals survived and exhibited normal body weight gain throughout the study. Macroscopic necropsy examination conducted on day 15 revealed no gross pathological lesions in any of the animals. In the subchronic study, Sprague-Dawley rats (40 males, 40 females) were divided into four same-sex groups (10 animals/group). Animals in each group were administered daily either 0, 30, 300 or 1000 mg of the test product per kg of body weight for over 90 days. All animals survived and showed no significant changes in their body weights and histopathology. Although some differences were observed between the treated and control animals in several parameters, they were generally not dose-related or considered to be of toxicological significance. In conclusion, the results from the two oral toxicity studies with male and female young adult rats indicated that the test preparation from hydrolyzed chicken sternal cartilage collagen (BioCell Collagen II) was well tolerated at all four doses tested.

    At present, collagen‑induced arthritis (CIA) is the best known and most extensively used model for the immunological and pathological characteristics of human rheumatoid arthritis (RA). This model is useful not only in aiding our understanding of the pathogenesis of this disease, but also in the development of new therapies. Bovine, porcine and human collagen has been used to induce CIA; however, response has been identified to vary between strains and injection conditions, and false positive results and reduced potency are common as a result of minor contaminants or deglycosylated protein. Therefore, in the present study, type II collagen (CII) was isolated and purified from chicken sternal cartilage and was found to successfully induce the RA model. Furthermore, T helper 17 (Th17) cells were observed to infiltrate the joint on day 45 following induction by CII. In vitro, expression of toll‑like receptor 2 (TLR2) increased in peritoneal macrophages stimulated by CII. In addition, blockage of TLR2 was identified to markedly decrease levels of TGF‑β and IL‑6 in the cell culture supernatant. The results indicate that CII isolated from chicken sternal cartilage may be recognized by TLR2 on macrophages, leading to TGF‑β and IL‑6 production and subsequent activation of Th17 cells which mediates CIA development.

    A new device to reduce the risk of post-operative complications following median sternotomy is proposed, made of a superelastic shape memory alloy and called a braided tubular superelastic (BTS) suture. This study compares the viability of the BTS suture with that of the standard monofilament stainless steel (MSS) suture. A custom test bench was developed to perform comparative testing of the two sternal closure systems. Sternal models made of polyurethane were closed using common wiring configurations. Static and dynamic tensile separation forces, up to a maximum of 1200 N, were then applied to the closed sternums. The MSS and BTS sutures are compared in terms of the force required to open completely the sternum, the compression force at the sternum midline, and the permanent sternum opening. With a smaller sternum opening and a higher tensile separation force, the MSS suture showed greater rigidity than the BTS suture. The BTS suture, however, displayed a better capacity to reapply compression forces at the sternum midline following the repetitive application and release of tensile separation forces. These results confirm the potential of the BTS suture technology, but further studies using cadaveric sterna are needed to attest definitely to the benefits of using the BTS suture to improve bone healing.

    The authors report one operated case of traumatic sternal segmental dislocation in a child, and propose a mechanism for this uncommon lesion. A fourteen year old boy was admitted in emergency for anterior chest pain, occurring during an exercise in parallel bars without any fall. X ray showed traumatic dislocation of the upper sternal segment. After 12 hours, because of bad clinical tolerance (pain, dyspnea with sweats and disphagia) reduction and plate stabilization (Senegas plate) was performed with immediate pain relief. The boy returned to school after 10 days. Plate was removed two months later after healing, with good clinical and radiological results. According to rare published cases, conservative treatment can be proposed in very young children because of dislocation remodeling. By others, in case of bad tolerance, surgical treatment is suggested despite the inconvenient of device's removal. The originality of this case is the indirect lesion mechanism. Hypothesis is given by authors. Treatment by plate is easy and gives immediate pain relief with good clinical and radiological results in teen-agers.

    The objective is to describe the 'Two Bridges Technique' (TBT), which has proven to be successful and has been the standard technique at our centre for vacuum-assisted closure (VAC) of post-sternotomy mediastinitis. An extensive literature search was performed in four databases to identify all published articles concerning VAC for post-sternotomy mediastinitis. Several VAC methods have been used; however, no article has described our specific technique. TBT consists of a two-bridges construction using two types of foam with different pore sizes, which ensures an equally divided negative pressure over the wound bed and stabilisation of the chest. This guarantees a continuous treatment of the sternal defect and prevents foam displacement. It maintains an airtight seal that prevents skin maceration and provides enough protection to avoid right ventricular rupture. The main advantage of TBT is the prevention of shifting or tilting of the foam during chest movements such as breathing or couching. Along with targeted antibiotic treatment, this alternative VAC technique can be an asset in the sometimes cumbersome treatment of post-sternotomy mediastinitis. © 2018 Medicalhelplines.com Inc and John Wiley & Sons Ltd.

    Sternal precautions are utilized within many hospitals with the aim of preventing the occurrence of sternal complications (eg, infection, wound breakdown) following midline sternotomy. The evidence base for sternal precaution protocols, however, has been questioned due to a paucity of research, unknown effect on patient outcomes, and possible discrepancies in pattern of use among institutions. The objective of this study was to investigate and document the use of sternal precautions by physical therapists in the treatment of patients following median sternotomy in hospitals throughout Australia, from immediately postsurgery to discharge from the hospital. A cross-sectional, observational design was used. An anonymous, Web-based survey was custom designed for use in the study. The questionnaire was content validated, and the online functionality was assessed. The senior cardiothoracic physical therapist from each hospital identified as currently performing cardiothoracic surgery (N=51) was invited to participate. The response rate was 58.8% (n=30). Both public (n=18) and private (n=12) hospitals in all states of Australia were represented. Management protocols reported by participants included wound support (n=22), restrictions on lifting and transfers (n=23), and restrictions on mobility aid use (n=15). Factors influencing clinical practice most commonly included "workplace practices/protocols" (n=27) and "clinical experience" (n=22). Limitations The study may be limited by response bias. Significant variation exists in the sternal precautions and protocols used in the treatment of patients following median sternotomy in Australian hospitals. Further research is needed to investigate whether the restrictions and precautions used are necessary and whether protocols have an impact on patient outcomes, including rates of recovery and length of stay.

    Although granulomatosis with polyangiitis (GPA) can affect a large number of organ systems and produce a broad spectrum of clinical symptoms, skeletal involvement is very rare, with the exception of facial bone involvement associated with destructive nasal and sinus inflammation. We describe here a 54-year-old man with sternal osteomyelitis and destructive arthritis around the sternoclavicular joint. Despite antibiotics and conventional immunosuppressive treatment, his symptoms deteriorated, and a new mass-like lung lesion was developed. A histopathologic analysis of the lung mass revealed chronic granulomatous inflammation with fibrinoid necrosis, and he was diagnosed with GPA. When a patient with a destructive inflammatory lesion has negative culture results and no response to conventional therapy, we propose that an aggressive approach is necessary for a pathologic diagnosis to exclude the possibility of GPA.

  2. The history of the management of sternal osteomyelitis and mediastinitis - from Hippocrates until today.

    Even during the time of Hippocrates, Galen and their colleagues recognized mediastinal affections. However, they were not considered with the surgical treatment.

    In Australia, particularly Western Australia, there is a relative paucity of contemporary population-specific morphometric standards for the estimation of sex from unknown skeletal remains. This is largely a historical artefact from lacking, or poorly documented, repositories of human skeletons available for study. However, medical scans, e.g. MSCT (multislice spiral computed tomography) are an ingenious and practical alternative source for contemporary data. To that end, this study is a comprehensive analysis of sternal sexual dimorphism in a sample of modern Western Australian (WA) individuals with a main purpose to develop a series of statistically robust standards for the estimation of sex. The sample comprises thoracic MSCT scans, with a mean of 0.9 millimeter (mm) slice thickness, on 187 non-pathological sterna. Following 3D volume rendering, 10 anatomical landmarks were acquired using OsiriX(®) (version 3.9) and a total of 8 inter landmark linear measurements were calculated using Morph Db (an in-house developed database application). Measurements were analyzed using basic descriptive statistics and discriminant function analyses, with statistical analyses performed using SPSS 19.0. All measurements are sexually dimorphic and sex differences explain 9.8-47.4% of sample variance. The combined length of the manubrium and body, sternal body length, manubrium width, and corpus sterni width at first sternebra contribute significantly to sex discrimination and yield the smallest sex-biases. Cross-validated classification accuracies, i.e., univariate, stepwise and direct function, are 72.2-84.5%, with a sex bias of less than 5%. We conclude that the sternum is a reliable element for sex estimation among Western Australians. Copyright © 2011 Elsevier Ireland Ltd. All rights reserved.

  9. Treatment of gram-positive deep sternal wound infections in cardiac surgery -experiences with daptomycin-

    Full Text Available Abstract The reported incidence of deep sternal wound infection (DSWI after cardiac surgery is 0.4-5% with Staphylococcus aureus being the most common pathogen isolated from infected wound sternotomies and bacteraemic blood cultures. This infection is associated with a higher morbidity and mortality than other known aetiologies. Little is reported about the optimal antibiotic management. The aim of the study is to quantify the application of daptomycin treatment of DSWI due to gram-positive organisms post cardiac surgery. We performed an observational analysis in 23 cases of post sternotomy DSWI with gram-positive organisms February 2009 and September 2010. When the wound appeared viable and the microbiological cultures were negative, the technique of chest closure was individualised to the patient. The incidence of DSWI was 1.46%. The mean dose of daptomycin application was 4.4 ± 0.9 mg/kg/d and the average duration of the daptomycin application was 14.47 ± 7.33 days. In 89% of the patients VAC therapy was used. The duration from daptomycin application to sternal closure was 18 ± 13.9 days. The parameters of infection including, fibrinogen (p = 0.03, white blood cell count (p = 0.001 and C-reactive protein (p = 0.0001 were significantly reduced after daptomycin application. We had no mortality and wound healing was successfully achieved in all patients. Treatment of DSWI due to gram-positive organisms with a daptomycin-containing antibiotic regimen is safe, effective and promotes immediate improvement of local wound conditions. Based on these observations, daptomycin may offer a new treatment option for expediting surgical management of DSWI after cardiac surgery.

  11. Partition of distinct chromosomal regions: negotiable border and fixed border.

    Science.gov (United States)

    Kimura, Akatsuki; Horikoshi, Masami

    2004-06-01

    Chromosomes are partitioned into distinct functional regions. For example, heterochromatin regions consist of condensed chromatin and contain few transcriptionally active genes, whereas euchromatin regions are less condensed and majority of active genes reside in the euchromatin regions. Because distinct regions reside in each chromosome, borders are accordingly established between these regions. A prevailing view of the borders is that they are 'walls' that actively inhibit communication between distinct regions on chromosomes. Although little is known about the molecular bases of these walls, specific DNA elements are considered to recruit these walls to define the positions of the borders. We call the borders established with this mechanism as 'fixed borders'. Past studies have identified various insulators (boundary DNA elements) that have been suggested to recruit fixed borders to them. Another mechanism, which we introduce and focus on in this review, does not require walls recruited by specific DNA elements at the chromosomal borders. Instead, the borders are defined by a balance of opposing enzymatic activities located at the opposite sides of the resultant borders. We name these borders 'negotiable borders'. Here we review some of the recent progress in the field that offer valuable insight into mechanisms of establishing structural and functional borders on chromosomes.

  19. Metrics for border management systems.

    Energy Technology Data Exchange (ETDEWEB)

    Duggan, Ruth Ann

    2009-07-01

    There are as many unique and disparate manifestations of border systems as there are borders to protect. Border Security is a highly complex system analysis problem with global, regional, national, sector, and border element dimensions for land, water, and air domains. The complexity increases with the multiple, and sometimes conflicting, missions for regulating the flow of people and goods across borders, while securing them for national security. These systems include frontier border surveillance, immigration management and customs functions that must operate in a variety of weather, terrain, operational conditions, cultural constraints, and geopolitical contexts. As part of a Laboratory Directed Research and Development Project 08-684 (Year 1), the team developed a reference framework to decompose this complex system into international/regional, national, and border elements levels covering customs, immigration, and border policing functions. This generalized architecture is relevant to both domestic and international borders. As part of year two of this project (09-1204), the team determined relevant relative measures to better understand border management performance. This paper describes those relative metrics and how they can be used to improve border management systems.

    Use of the internal thoracic artery in coronary revascularization confers excellent benefit. We assessed the impact of skeletonization on the incidence of postoperative sternal wound infection in patients undergoing coronary artery bypass grafting. We also investigated whether there is an advantage in using this technique when harvesting both internal thoracic arteries in high-risk groups, such as diabetic patients. Skeletonization was associated with beneficial reduction in the odds ratio of sternal wound infection (odds ratio, 0.41; 95% confidence interval, 0.26 to 0.64). This effect was more evident when analyzing diabetic patients undergoing bilateral internal thoracic artery grafting (odds ratio, 0.19; 95% confidence interval, 0.10 to 0.34). 2010 The Society of Thoracic Surgeons.

    Conclusion: Management of DSWI is tedious, has prolonged hospital stay and is associated with high morbidity and mortality rates. Management of DSWI must be personalized according to findings on exploration of the sternal wound and flap coverage must be initiated only when the patient is bacteriologically free. Both PMF and/or VOF provided high acceptable success rate defined as survival free of DSWI recurrence.

  2. Anatomic study of the vascular perfusion of the sternum and its clinical relevance in deep sternal wound infection

    2017-06-01

    Full Text Available Introduction: Deep sternal wound infections (DSWI are a rare but devastating complication after median sternotomy. Minor perfusion in bone and soft tissue, especially after recruiting the internal mammary artery for bypass supports the development of wound infection and nonunion of the sternal bone. The aim of the study was the macroscopic and radiological presentation of the vascular system supplying the sternum, in particular the compensating blood supply routes in the event that the internal mammary artery is no longer available after use as a bypass vessel.Method: This anatomic study was carried out on the anterior chest wall of 7 specimens. The thorax plates of 7 specimens were analyzed macroscopically after microsurgical preparation. Different anatomic preparations were produced using different contrast or form-giving substances. Radiological analysis and three-dimensional reconstructions were performed to show alternative, collateral sternal vessel perfusion under estimation of the loss of the internal thoracic artery due to a bypass.Results: The length of the ITA (internal thoracic artery, measured from the beginning of the first rib to the division into the superior epigastric artery and musculophrenic artery, was an average of 16.3 cm. On average, 18.5 branches were delivered from each artery, 10 medially to the sternum supply, and the intercostal muscle. Conclusion: Our analysis gives an overview of the macroanatomic vessel system supplying the sternal bone, describing especially a common trunk deriving from the ITA and supplying multiple branches and playing an important role in building a collateral circulation of the sternum.For better evaluation, in vivo CT analysis with contrast media should be performed in patients prior to the operation and directly after the use of the double ITA to demonstrate the change in perfusion of the sternum.In the future, preconditioning of the sternum by coiling the deriving branches could become an

    Currently, the majority of patients who develop Hodgkin's disease can be cured with radiotherapy and/or chemotherapy. A long follow up of cured patients has shown that the cumulative toxicity from treatment related complication rivals the mortality from Hodgkin's disease. We present a 38-year old male with Hodgkin's disease, treated with radiation and chemotherapy, who developed cardiac infarction and severe mediastinal fibrosis. After median sternotomy for cardiac bypass operation, he suffered from sternal osteitis and superior mediastinitis. A radical debridement must be avoided to protect the bypassed conduit embedded in the extended severe mediastinal fibrosis. Then after appropriate debridement and management of methicillin-resistant Staphylococcus aureus (MRSA) infection, latissimus dorsi myocutaneous flap transfer and use of vancomycin-impregnated cement beads achieved infection control. In this study we present our experience with bibliographical discussion. With the concept presented in this study, however, a consistent cure and prevention from subsequent infection-related morbidity and mortality were achieved even in the subset of the most severe, recalcitrant cases of sternal osteitis, and with an unacceptable rate of complications. This justifies the invasive nature of the procedure and suggests its application not only as a salvage operation for failures after previous interventions, but also as a primary approach for severe sternal osteomyelitis.

    We report our experience in use of Vacuum-assisted closure therapy (VAC) in the treatment of poststernotomy wound infection with emphasis on recurrent wound-related problems after use of VAC and their treatment. Between July 2000 and June 2003, 2706 patients underwent various cardiac procedures via median sternotomy. Forty-nine patients with postoperative sternal wound infection (1.9%) were managed with VAC. Wounds were classified as either superficial sternal wound infection (28 patients) or deep sternal wound infection (21 patients). In the superficial sternal wound infection group, 23 patients had VAC as definitive treatment (GroupA), while five patients (Group B) had VAC followed by surgical closure. Similarly, in the deep sternal wound infection group, 12 patients had VAC as definitive treatment (Group C), while nine patients had VAC followed by surgical closure (Group D). Patients were discharged after satisfactory wound closure. Upon discharge patients were followed up at interval of three to six months. Recurrent sternal problems when identified were investigated and additional surgical procedures were carried out when necessary. There were nine deaths, all due to unrelated causes except in one patient who died of right ventricular rupture (Group C). Nine patients in Group A had recurrent wound problems of which six had VAC system for > 21 days. Three patients underwent extensive debridement due to sternal osteomyelitis. All eight patients in Group B presented with chronic wound-related problems and underwent multiple debridements. Four patients had laparoscopic omental flaps. In contrast 14 patients (Group B and D) who were treated with shorter duration of VAC followed by either a flap or direct surgical closure, did not present with recurrent problems. VAC therapy is a safe and reliable option in the treatment of sternal wound infection. However, prolonged use of VAC system as a replacement for surgical closure of sternal wound appears to be associated

    Objective: To evaluate the effects of the degree of sternal depression on the cardiac rotation in pectus excavatum by using spiral CT. Methods: Spiral CT features of 32 patients with surgically corrected pectus excavatum were retrospectively reviewed. They included 27 males and 5 females ranging in age from 6 months to 17 years (mean, 6.3 years). Analysis was based on relationship among the degree of sternal depression, CT depression index, cardiac rotation angle, and PV angle. Results: 32 cases of pectus excavatum presented the sternal depression (21 ± 7) mm, CT depression index 2.9 ± 1.8, cardiac rotation angle (55.9 ± 9.8) degree, and PV angle (49.8 ± 14.0) degree, respectively. The sternal depression (17 mm) in cases with CT depression index less than 2.4 was smaller than those with CT depression index 2.4-2.9 (21 mm) and CT depression index larger than 2.9 (27 mm) (F 5.39, P<0.01). Cardiac rotation angle (49.7 degree) in cases with CT depression index less than 2.4 was smaller than those with CT depression index 2.4-2.9 (55.5 degree) and CT depression index larger than 2.9 (66.9 degree) (F=7.44, P<0.01). PV angle (58.7 degree) in cases with CT depression index less than 2.4 was larger than those with CT depression index 2.4-2.9 (46.5 degree) and CT depression index more than 2.9 (42.4 degree) ( F=3.33, P<0.05). Cardiac rotation angle of pectus excavatum had positive correlation with the CT depression index (γ=0.73, P<0.01). Conclusion: Spiral CT is a better tool for revealing chest deformity and corresponding cardiac rotation. The degree of sternal depression in pectus excavatum directly influences the cardiac rotation, and they had positive correlation. (authors)

    Sternal synthesis after median sternotomy, a conventional access practice in thoracic and cardiac surgery, is at the basis of severe complications, often impairing the clinical outcome of surgical interventions. In this work, we propose the use of an acellular biomaterial scaffold, to be interposed across the fracture rime during closure operations, directly exposing the biomaterial to bone marrow, in order to expedite healing process. A rabbit model of median sternotomy was performed and an electrospun scaffold composed of a hydroxyapatite-loaded absorbable biopolymer (poly-L: -lactide), shaped into a fibrillar structure, was used. CT follow-up confirmed a complete healing in the scaffold-treated group 1 week before the control. Histological evaluation demonstrated presence of newly formed bone trabeculae among scaffold fibers showing a higher degree of maturity with respect to the control untreated group. The proposed approach is able to both guide a more rapid healing and modulate inflammatory response across the wound site, resulting in improved healing and tissue remodeling with respect to conventional closure technique.

    Sternal pores are important features for identification of male thrips, especially within the subfamily Thripinae. They vary in shape, size and distribution even between species of one genus. Their functional role is speculated to be that of sex- and/or aggregation pheromone production. Yet, sexual aggregations are not reported in Echinothrips americanus, known to have sternal pores, while we observed aggregations in Megalurothrips sjostedti, previously reported to lack them. We examined the sternal glands and pores of the thripine species E. americanus and M. sjostedti males, in comparison with those of Frankliniella occidentalis using light microscopy, as well as scanning and transmission electron microscopy. Pore plates of F. occidentalis were ellipsoid and medial on sternites III-VII, while in E. americanus they were distributed as multiple micro pore plates on sternites III-VIII. In M. sjostedti they appeared as an extremely small pore in front of the posterior margin of each of sternites IV-VII. Pore plate and pore plate area were distributed similarly on sternites III-VII in F. occidentalis. However, in E. americanus the total pore plate area increased significantly from sternites III to VIII. Ultrastructure of cells associated with sternal glands showed typical characteristics of gland cells that differ in size, shape and number. The function of sternal glands is further discussed on the basis of morphological comparisons with other thrips species. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Full Text Available Modernity has been creating spaces, new boundaries and borders, as metaphysical, mythological and symbolic marks of physical and imaginary territories. Modern space and its borders are metaphors, boundaries that are created, walls that rise to identify with some and categorize others. In this short paper we want to approach the problem of the transformation of the idea of border (geographical, cultural, symbolic, etc., for a reflection on the transformations of that civilized obsession called border. The border has always been a reference in facing the identities, names, symbols, different imaginary: it is more confrontational line between two otherness. From the previous framework, we reflect on Turnerian mythology, as we believe that behind the creation of the imagination of the northern border is the mythical vision of the American frontier as ideological canon that explains and confirms the presence of the white race in a border re–made in the image and likeness of the “American Dream”. Frederick Turner’s reflection on the role of the frontier in American history is not only the study of the importance of progress towards the West but –even more so, is the analysis of meaning that had the American frontier as a historical process that ended in 1893, as Turner said, but rather extended into the twentieth century and continues to constantly shaping the process of territorialization of the border.

    A top concern in homeland security efforts is the lack of ability to monitor the thousands of miles of open border with our neighbors. It is not currently feasible to continually monitor the borders for illegal intrusions. The MicroSensor System (MSS) seeks to achieve a low-cost monitoring solution that can be efficiently deployed for border patrol applications. The modifications and issues regarding the unique requirements of this application will be discussed and presented. The MicroSensor System was developed by the Defense Microelectronics Activity (DMEA) for military applications, but border patrol applications, with their unique sensor requirements, demand careful adaptation and modification from the military application. Adaptation of the existing sensor design for border applications has been initiated. Coverage issues, communications needs, and other requirements need to be explored for the border patrol application. Currently, border patrol has a number of deficiencies that can be addressed with a microsensor network. First, a distributed networked sensor field could mitigate the porous border intruder detection problem. Second, a unified database needs to be available to identify aliens attempting to cross into the United States. This database needs to take unique characteristics (e.g. biometrics, fingerprints) recovered from a specialized field unit to reliably identify intruders. Finally, this sensor network needs to provide a communication ability to allow border patrol officers to have quick access to intrusion information as well as equipment tracking and voice communication. MSS already addresses the sensing portion of the solution, including detection of acoustic, infrared, magnetic, and seismic events. MSS also includes a low-power networking protocol to lengthen the battery life. In addition to current military requirements, MSS needs a solar panel solution to extend its battery life to 5 years, and an additional backbone communication link

    Full Text Available Patients with an anterior mediastinal mass pose significant risk for cardiorespiratory compromise during surgical procedures and general anesthesia. Several techniques have been described to reverse airway obstruction in these patients. In extreme circumstances, patients may require cardiac bypass or extracorporeal membrane oxygenation (ECMO until definitive treatment of the mass and patient stabilization is achieved. We present a case in which the RulTract® system was used for emergency sternal elevation as a bridge to ECMO in acute respiratory collapse in an 11-year-old female with a minimally symptomatic anterior mediastinal mass.

    Congenital sternal cleft is a rare chest wall malformation. Because of the flexibility of the chest in infants, surgical repair should be performed by primary closure in the neonatal period. In adolescents and adults, different techniques have been suggested to overcome the lack of sternal bone tissue. We describe a very rare case of an 18-year-old woman with a complete bifid sternum associated with pectus excavatum for whom a satisfactory cosmetic and functional result was obtained by adequate surgical planning, which entailed a combination of two standardized surgical techniques.

    Fire knows no borders and neither should the tools for fighting it. It was with this aim in mind that delegates from 14 different countries came to CERN at the beginning of April to take part in the twentieth of a series of twice-yearly international conferences organised by the Federation of European Union Fire Officer Associations (FEU). This latest conference allowed participants to keep abreast of new developments with a view to improving the safety techniques used in their own countries. The first in the series was held in Tampere, Finland, in 1994. The FEU network's objective is to harmonise safety policies and modernise the fire-fighting programme. In particular, it aims to develop an international system for testing hotels' fire alarm systems and to improve language learning in all countries' fire-fighting services.

    Full Text Available Case summary Cranial ventral midline hernias, most often congenital, can be associated with other congenital abnormalities, such as sternal, diaphragmatic or cardiac malformations. A 4-year-old multiparous queen with a substernal hernia was admitted for evaluation of a mammary mass. During CT examination, a bifid sternum, the abdominal hernia containing the intestines, spleen, omentum, three fetuses, a mammary mass and an incidental peritoneopericardial diaphragmatic hernia were identified. Surgery consisted of a standard ovariohysterectomy and repair of the peritoneopericardial hernia. Primary closure of the abdominal hernia was attempted but deemed impossible even after the ovariohysterectomy, splenectomy and a partial omentectomy. An external abdominal oblique muscle flap was used to close with no tension on the cranial part of the hernia. One month postoperatively, the queen had no respiratory abnormalities and the herniorrhaphy was fully healed. Relevance and novel information This case is the first description of a 4-year-old multiparous pregnant queen with complex congenital malformations and surgical correction of a peritoneopericardial hernia and a 6 × 8 cmsubsternal hernia with an external abdominal oblique muscle flap. Life-threatening sequelae associated with large abdominal hernias can be attributed to space-occupying effects known as loss of domain and compartment syndrome, which is why a muscle flap was used in this case. The sternal cleft was not repaired because of the size of the cleft and the age of the cat.

  9. Clavicles, interclavicles, gastralia, and sternal ribs in sauropod dinosaurs: new reports from diplodocidae and their morphological, functional and evolutionary implications.

    2013-03-01

    Ossified gastralia, clavicles and sternal ribs are known in a variety of reptilians, including dinosaurs. In sauropods, however, the identity of these bones is controversial. The peculiar shapes of these bones complicate their identification, which led to various differing interpretations in the past. Here we describe different elements from the chest region of diplodocids, found near Shell, Wyoming, USA. Five morphotypes are easily distinguishable: (A) elongated, relatively stout, curved elements with a spatulate and a bifurcate end resemble much the previously reported sauropod clavicles, but might actually represent interclavicles; (B) short, L-shaped elements, mostly preserved as a symmetrical pair, probably are the real clavicles, as indicated by new findings in diplodocids; (C) slender, rod-like bones with rugose ends are highly similar to elements identified as sauropod sternal ribs; (D) curved bones with wide, probably medial ends constitute the fourth morphotype, herein interpreted as gastralia; and (E) irregularly shaped elements, often with extended rugosities, are included into the fifth morphotype, tentatively identified as sternal ribs and/or intercostal elements. To our knowledge, the bones previously interpreted as sauropod clavicles were always found as single bones, which sheds doubt on the validity of their identification. Various lines of evidence presented herein suggest they might actually be interclavicles - which are single elements. This would be the first definitive evidence of interclavicles in dinosauromorphs. Previously supposed interclavicles in the early sauropodomorph Massospondylus or the theropods Oviraptor and Velociraptor were later reinterpreted as clavicles or furculae. Independent from their identification, the existence of the reported bones has both phylogenetic and functional significance. Their presence in non-neosauropod Eusauropoda and Flagellicaudata and probable absence in rebbachisaurs and Titanosauriformes shows a

    The objectives of this study were to obtain standard echocardiographic measurements from healthy Border Collies and to compare these measurements to those previously reported for a general population of dogs. Standard echocardiographic data were obtained from twenty apparently healthy Border Collie dogs. These data (n = 20) were compared to data obtained from a general population of healthy dogs (n = 69). Border Collies were deemed healthy based on normal history, physical examination, complete blood count, serum biochemical profile, electrocardiogram, and blood pressure, with no evidence of congenital or acquired heart disease on echocardiographic examination. Standard two dimensional, M-mode, and Doppler echocardiographic measurements were obtained and normal ranges determined. The data were compared to data previously obtained at our hospital from a general population of normal dogs. Two dimensional, M-mode, and Doppler reference ranges for healthy Border Collies are presented in tabular form. Comparison of the weight adjusted M-mode echocardiographic means from Border Collies to those from the general population of dogs showed Border Collies to have larger left ventricular systolic and diastolic dimensions, smaller interventricular septal thickness, and lower fractional shortening. There are differences in some echocardiographic parameters between healthy Border Collies and the general dog population, and the echocardiographic reference ranges provided in this study should be used as breed specific reference values for Border Collies.

    One year ago, a 42-year-old woman underwent aortic root replacement because of a pseudoaneurysm that developed at the site of an anastomosis after ascending aortic replacement for acute aortic dissection. Six months later, she complained of fever and cough. A computed tomography revealed recurrence of the peudoaneurysm at the proximal anastomosis of the aortic root replacement. After emergency re-do aortic root replacement, she was admitted to intensive care unit (ICU) without sternal closure because of mediastinitis. The mediastinitis was managed by debridement and lavage drainage, followed by vacuum-assisted closure (VAC) treatment. The VAC treatment facilitated wound healing and active rehabilitation using a portable device. Finally, the wound was closed completely using a skin graft. VAC treatment is considered very useful in a case of post-sternotomy madiastinitis.

    2013-05-01

    The development of the sternal extremity of the clavicle was examined prospectively with magnetic resonance imaging (MRI) for forensic bone age assessment. The objectives were to examine whether these results were comparable with the literature on plain radiography and CT, to provide age prediction intervals that correctly reflect the high variability in clavicular growth among individuals and to investigate whether MRI of the clavicle can be used to differentiate between individuals younger or older than 18 years. The clavicles of 220 volunteers (16-26 years) were examined with 3-T MRI and evaluated according to the Schmeling and Kreitner classification (Schmeling, Int J Legal Med 118:5-8, 2004; Kreitner, Eur Radiol 8:1116-1122, 1998). An additional hand/wrist radiograph was taken and evaluated according to Greulich and Pyle (1959). After a descriptive analysis, a multivariate ordinal regression model was fitted and embedded in a Bayesian framework based on Thevissen et al. (Int J Legal Med 124:35-42, 2009). The descriptive results were concordant with the literature, although the Kreitner classification is recommended and simultaneous evaluation of the hand is considered a basic requirement (Schmeling, Int J Legal Med 118:5-8, 2004). The 95 % credibility interval for both genders with bilateral stage IV is 20-26 years. The corresponding estimated probability of being younger than 18 years is 0.8 % in females and 0.2 % in males. MRI of the sternal extremity of the clavicle can be used to differentiate between being younger or older than 18, but a simultaneous evaluation of the hand/wrist is essential. Future evaluation of the predictive performance of the model, using comparable but larger reference samples, is necessary to validate these results.

    Purpose. - To assess the value of treatment-planning related parameters namely, the breast volume; the distance of the inferior field border to diaphragm; and the cardio-thoracic ratio for left-tangential breast irradiation. Patients and methods. - Treatment plans of 27 consecutively left-sided breast cancer patients after breast conserving surgery were evaluated for several parameters concerning heart-irradiation. We measured the heart distance respective to the cardio-thoracic ratio and the distance of the inferior field border to diaphragm, as well as the breast volume in correlation with the irradiated heart volume. Results. - The mean heart and left breast volumes were 504 cm 3 and 672.8 cm 3 , respectively. The mean heart diameter was 13.4 cm; the mean cardio-thoracic ratio 0.51 and the mean distance of the inferior field border to diaphragm was 1.4 cm. Cardio-thoracic ratio (p = 0.01), breast volume (p = 0.0002), distance of the inferior field border to diaphragm (p = 0.02) and central lung distance (p = 0.02) were significantly correlated with the measured heart distance. A significant correlation was also found between cardio-thoracic ratio, breast volume and distance of the inferior field border to diaphragm with the irradiated heart volume measured by V10, V20 and V40. Conclusion. - The verification of parameters like cardio-thoracic ratio, distance of the inferior field border to diaphragm and breast volume in left-sided breast cancer patients may help in determining which patients could benefit from more complex planning techniques such as intensity-modulated radiotherapy to reduced risk of late cardiac injury.

    2013-11-01

    Boundary effect analysis is related to border policy making in the cross-border ethnic area. The border effect literatures show that geographic boundaries have obvious impacts on economic, social and cultural relations in both sides of a nation border. Particularly in cross-border ethnic areas, each ethnic group has strong internal spatial structure relevance, and the boundary effect is more obvious. However, most of China's border areas are cross-border ethnic areas, each of border issues is unique. Under this perspective, we analyze the border effects of various boundaries can provide basis for formulating border management policies. For small scale of cross-border ethnic minority areas, how to formulate the boundary management policy is a good question to explore. This paper is demonstrated by a study of the impact of border management policies in Dehong Dai and Jingpo Autonomous Prefecture in Yunnan Province at the border area to Burma. The comparative method is used to analysis the border management policies in past 50 decades for the border area of Yunnan Province .This research aims to define trends within border policy and its influences to national security. This paper also examines Wendy Brown's liberal theory of border management policy. We found that it is not suitable for Sino-Burma border area. The conclusion is that the changes or instability of international economic and political situation has more influence to this cross-border ethnic area, and only innovative policy will be effective in cross-border ethnic area. So the border management policies should reflect the change of international context.

  6. Old Borders and New Bordering Capabilities: Cities as Frontier Zones

    Directory of Open Access Journals (Sweden)

    Saskia Sassen

    2015-12-01

    Full Text Available The global city is a new frontier zone. Deregulation, privatization, and new fiscal and monetary policies create the formal instruments to construct their equivalent of the old military “fort”. The city is also a strategic frontier zone for those who lack power, and allows the making of informal politics. At the same time the border is a mix of regimes, marked by protections and opportunities for corporations and high-level professionals, and implies confinement, capture and detention for migrants. The essay discusses the transformation of the city in a frontier zone and analyses the separation between the capabilities entailed by territoriality and the geographic territory tout court. The analysis focuses on the effects of neoliberal policies that, far from making this a borderless world, have actually multiplied the bordered spaces that allow firms and markets to move across conventional borders. Cities are therefore one of the key sites where new neoliberal norms are made and where new identities emerge.

    2011-09-01

    Full Text Available Abstract Negative-pressure wound therapy, commercially known as vacuum-assisted closure (V.A.C.® therapy, has become one of the most popular (and efficacious interim (prior to flap reconstruction or definite methods of managing deep sternal wound infection. Complications such as profuse bleeding, which may occur during negative-pressure therapy but not necessarily due to it, are often attributed to a single factor and reported as such. However, despite the wealth of clinical experience internationally available, information regarding certain simple considerations is still lacking. Garnering information on all the factors that could possibly influence the outcome has become more difficult due to a (fortunate decrease in the incidence of deep sternal wound infection. If more insight is to be gained from fewer clinical cases, then various potentially confounding factors should be fully disclosed before complications can be attributed to the technique itself or improvements to negative-pressure wound therapy for deep sternal wound infection can be accepted as evidence-based and the guidelines for its use adapted. The authors propose the adoption of a simple checklist in such cases.

  9. Cross-border reprogenetic services.

    Couture, V; Drouin, R; Tan, S-L; Moutquin, J-M; Bouffard, C

    2015-01-01

    The purpose of this review is to synthesize the current knowledge on the international movement of patients and biopsied embryo cells for pre-implantation genetic diagnosis and its different applications. Thus far, few attempts have been made to identify the specific nature of this phenomenon called 'cross-border reprogenetic services'. There is scattered evidence, both empirical and speculative, suggesting that these services raise major issues in terms of service provision, risks for patients and the children-to-come, the legal liabilities of physicians, as well as social justice. To compile this evidence, this review uses the narrative overview protocol combined with thematic analysis. Five major themes have emerged from the literature at the conjunction of cross-border treatments and reprogenetics: 'scope', 'scale', 'motivations', 'concerns', and 'governance'. Similar themes have already been observed in the case of other medical tourism activities, but this review highlights their singularity with reprogenetic services. It emphasizes the diagnostic and autologous feature of reprogenetics, the constant risk of misdiagnosis, the restriction on certain tests for medically controversial conditions, and the uncertain accessibility of genetic counseling in cross-border settings. © 2014 John Wiley & Sons A/S.

    Xu, J; Liu, H

    1997-09-01

    Yunnan Province, due its international borders with Myanmar, Vietnam and Lao PDR has a large number of imported cases of malaria, including a high proportion of Plasmodium falciparum, as a result of the mobility of the population. This movement is due to workers coming from other provinces where there is no malaria to work in the productive tropical lowlands. Chinese nationals who have gone to work in neighboring countries, border trade and refugees from Myanmar. Much of Yunnan is peopled by ethnic minorities living in remote mountainous and forested areas which are difficult to reach. However, surveillance has been strengthened by training 3,900 primary health care workers and combining the search for visiting foreigners, returning Chinese and people from other provinces with public security, customs formalities and employers. Any visitor detected by these services is obliged to have a blood slide taken. This has resulted in an earlier and more complete detection of malaria cases, reducing incidence from 19.19 to 12.12/10,000 in the border area over the last 10 years. This is despite a considerable increase in population movement and the threat of drug resistant malaria.

    Full Text Available This article analyzes the border paradiplomacy used by more than 50 municipalities from Bolivia, Chile and Peru, named “Aymaras without Borders Strategic Alliance”. In spite of the differentiated historical construction of national identities, according to a literature review, it could be argued that there is an unprecedented border relation between these three countries. Furthermore, it is possible to conclude that this non-violent strategy has been successful in the last 15 years.

  14. Nuclear risk behind the border?

    International Nuclear Information System (INIS)

    Varjoranta, T.

    1995-01-01

    The condition of nuclear wastes and facilities in Russia and in the Baltic countries arouses concern in Finland. Russia has two large nuclear power plants, nuclear weapons, over 300 nuclear submarine reactors and more than ten icebreaker reactors in close proximity to Finland's eastern border. The Lithuanian Ingalina nuclear power plant is also situated close to Finland. Following the Chernobyl accident, considerable improvements have been made to the technology and safety culture of Russian nuclear power plants, for instance, through international support programmes. The unstable social climate in Russia is, however, slowing progress down. Yet it is certain that no accident in the power plants near Finland's borders would cause immediate health risks in Finland, or would threaten the health of large numbers of people in the long term, either. Russia has not always taken proper care of its nuclear waste. In particular, spent fuel from nuclear submarines stored in Northern Russia causes problems. Russians have disposed of some waste by dumping ship reactors, with their fuel, into the Arctic Ocean. Some nuclear-powered submarines have sunk with all their crew. Russia has also conducted many nuclear tests in the vicinity of Finland. (orig.)

  20. The Borders of "Shopluk" and/or Shops without Borders

    Directory of Open Access Journals (Sweden)

    P. Hristov

    2015-08-01

    Full Text Available A historic and cultural region exists at the heart of the Balkans, known in geographic and ethnographic research as Shopluk. This is a region in which, over the last 150 years, state boundaries were moved several times as a result of 5 different wars. Today, the historic Shopluk is where the borders of three nations converge – Republic of Bulgaria, Republic of Serbia and the Republic of Macedonia – and, during the last decade, the region was declared one of the “Euroregions” on the Balkans. Despite the historical similarities in traditional culture and language of this population, in the 19th century it became a subject of nationalist ambitions and a propaganda “wars” between the new national states of Serbia and Bulgaria. The joining of Bulgarian-inhabited parts of Shopluk (the regions of today’s Dimitrovgrad and Bosilegrad in Serbia to the Kingdom of Serbs, Slovenes and Croats in 1919 created a long-lasting tension between the two countries, some residues of which can be felt in everyday relations even today. On the other hand, it has been a century-long tradition for men in this region to take part in seasonal labour migrations all over the Balkan Peninsula, despite political borders. In this way, preserving their cultural and lingual specifics, the groups of seasonal workers – migrants from Shopluk, became a bridge for cultural interaction and exchange with other regions in the neighbour countries. Even though today the population of Shopluk exhibits different national identities, historical similarities in culture and language can turn the Euroregion between Nish, Sofia and Skopje from one of the poorest on the Balkans to one of the most integrated and prosperous.

    Full Text Available La mediastinitis es una de las complicaciones más graves de la cirugía cardíaca. Aparece en el 0,5-5 % de las esternotomías y esta incidencia es mucho mayor en pacientes diabéticos, obesos, inmunodeprimidos, con enfermedad pulmonar obstructiva crónica (EPOC, etc. Presentamos el caso de una paciente diabética, obesa mórbida, que sufre mediastinitis tras doble by-pass coronario. Para la cobertura del defecto se empleó un colgajo de epiplon tunelizado transdiafragmático. El colgajo omental permite cubrir grandes defectos además de que posee capacidad antimicrobiana y favorece la revascularización tisular. Las características de este colgajo hacen que actualmente deba considerarse como primera elección en pacientes con grandes defectos esternales y trastornos de la inmunidad y la cicatrización.Mediastinitis is one of the most serious complications from cardiac surgery. It is reported to occur in 0'5-5 % of sternotomy incisions, and this incidence is much higher in diabetic patients, obese, immunocompromised, COPD, etc. We report a case of a diabetic and morbid obese woman suffering mediastinitis after double coronary bypass surgery. For the reconstruction a transdiaphragmatic tunnelled omental flap was used. The omentum is useful to cover large defects. It has antiinfective properties and promotes revascularization of neighbouring tissues. Omental flap can be a highly effective treatment for patients with large sternal wounds and immune disorders and wound healing disorders.

    Full Text Available Abstract Background Sternal wound infection (SWI is an uncommon but potentially life-threatening complication of cardiac surgery. Predisposing factors for SWI are multiple with varied frequencies in different studies. The purpose of this study was to assess the incidence, risk factors, and mortality of SWI after coronary artery bypass grafting (CABG at Tehran Heart Center. Methods This study prospectively evaluated multiple risk factors for SWI in 9201 patients who underwent CABG at Tehran Heart Center between January 2002 and February 2006. Cases of SWI were confirmed based on the criteria of the Centers for Disease Control and Prevention. Deep SWI (bone and mediastinitis was categorized according to the Oakley classification. Results In the study period, 9201 CABGs were performed with a total SWI rate of 0.47 percent (44 cases and deep SWI of 0.22 percent (21 cases. Perioperative (in-hospital mortality was 9.1% for total SWI and about 14% for deep SWI versus 1.1% for non-SWI CABG patients. Female gender, preoperative hypertension, high functional class, diabetes mellitus, obesity, prolonged intubation time (more than 48 h, and re-exploration for bleeding were significant risk factors for developing SWI (p = 0.05 in univariate analysis. In multivariate analysis, hypertension (OR = 10.7, re-exploration (OR = 13.4, and female gender (OR = 2.7 were identified as significant predictors of SWI (p Conclusion Rarely reported previously, the two risk factors of hypertension and the female gender were significant risk factors in our study. Conversely, some other risk factors such as cigarette smoking and age mentioned as significant in other reports were not significant in our study. Further studies are needed for better documentation.

    2008-10-01

    In an aged human female cadaver a left accessory aberrant colic artery (LAACA) was observed and studied. It originated from the superior mesenteric artery at 3 cm proximal to the middle colic artery, at the inferior border of pancreas, passing over Treitz's muscle and continued covered by the superior duodenal fold where it crossed the inferior mesenteric vein. Further, it continued with a satellite vein anterior to the left renal vein and the anterior branch of the renal artery. The LAACA divided into an ascending branch and a descending one, anastomosed with the middle colic and proper left colic arteries; between its two primary branches and the splenic flexure of colon, a hypovascular area was observed. The surgical relevance of the LAACA detailed anatomy mainly relates to specific procedures performed in left colectomies and nephrectomies.

  16. Revitalising Borders: Memory, Mobility and Materiality in a Latvian-Russian Border Region

    Directory of Open Access Journals (Sweden)

    Aija Lulle

    2016-04-01

    Full Text Available In this paper I investigate how an international border is 'revitalised' in political discourses as opposed to lived experiences. Based on narratives I have collected from border dwellers on both sides of the current border between Latvia and Rus-sia and placing them into a broader context of current border debates, I analyse how geographical and social mobility is remembered from Soviet times and reworked in current contexts. I argue that while politically the border is revitalised through aban-doning and forgetting the Soviet past and through the idea of constant threats in the future, locally it is revitalised through giving a life to the abandoned: memories of 'vigorous times' in life-courses and material things. People who dwell at the border did not move themselves: the international border moved several times in one cen-tury leaving border dwellers' memories and significant places on the 'other' side. I focus on how these borders were crossed in the past, how they are (not crossed now, and the social meanings assigned to these circumstances. In the current con-text I follow diverse paths of reasoning that describe how the uneven flow of goods and people through the Latvian-Russian border shapes the power dynamic against which the people living in the border area used to reconstruct imaginaries of 'Soviet times' versus 'Europe' and 'vigorous times' versus decline.

Na correção desta complicação, a associação de técnicas de cirurgia plástica, com a utilização de retalhos miocutâneos ou musculares, permitiu mais rápida recuperação dos pacientes, sem que tivéssemos óbitos nesta série. Os resultados estético e funcional foram considerados excelentes, com três pequenas deiscências tratadas ambulatorialmente. A identificação do germe através de cultura e a orientação do tratamento pelo antibiograma também se mostraram de grande importância, ao lado das técnicas cirúrgicas empregadas.

    Purpose: to evaluate whether scintigraphy with technetium-99m-labeled ceftizoxime ({sup 99m}Tc-CFT) can differentiate mediastinitis from aseptic inflammation associated with sternotomy. Methods: twenty female Wistar rats were randomly distributed into four groups: S (control) -partial upper median sternotomy with no treatment; SW (control) - sternotomy and treatment of sternal wounds with bone wax; SB - sternotomy and infection with Staphylococcus aureus; SWB - sternotomy with bone wax treatment and bacterial infection. Scintigraphy with {sup 99m}Tc-CFT was performed eight days after surgery and images were collected 210 and 360 min after infusion of the radiopharmaceutical. Results: no animals exhibited clinical signs of wound infection at the end of the experiment, although histological data verified acute inflammatory response in those experimentally infected with bacteria. Scintigraphic images revealed that tropism of {sup 99m}Tc-CFT to infected sternums was greater than to their non-infected counterparts. Mean counts of radioactivity in bacteria-infected sternal regions (SB and SWB) were significantly higher (p = 0.0007) than those of the respective controls (S and SW).Conclusion: scintigraphy with technetium-99m-labeled ceftizoxime is a method that can potentially detect infection post sternotomy and differentiate from aseptic inflammation in animals experimentally inoculated with S. aureus (author)

    2013-01-01

    To examine the impact of VAC therapy on mortality of patients with sternal wound infections after cardiothoracic surgery. Controversial results regarding mortality of patients with sternal wound infections were published. We performed a systematic search in PubMed and Scopus. Mortality was the primary outcome of the meta-analysis. Recurrences, complications and length of stay were secondary outcomes. Twenty-two retrospective studies including 2467 patients were eligible for inclusion. Patients treated with VAC had significantly lower mortality compared to those treated without VAC [2233 patients, RR = 0.40, (95% CI 0.28, 0.57)]. This finding was consistent regardless of the study design, the exclusion of studies with positive findings, the criteria for establishment of the compared groups, the time of mortality assessment or the type of infections under study, provided that adequate data was available. VAC therapy was associated with fewer recurrences (RR = 0.34, 95% CI: 0.19-0.59). The meta-analysis did not show any difference in the length of stay (RR = -2.25, 95% CI: -7.52-3.02). VAC therapy was associated with lower mortality than other surgical techniques in retrospective cohorts of patients with DSWIs following cardiothoracic surgery.

(1) SonoVue stained the left heart chambers of the patients right away after the right heart chambers had been stained. Endocardial border delineation of the left heart in 90 patients were all improved by SonoVue. (2) SonoVue can well display myocardial opacification (3) No serious adverse events occurred throughout the study. All nonserious adverse events were minor, mild, and rapidly self-resolving. Total incidence of adverse events was 6.8% and the incidence of adverse events possibly related to SonoVue was 1.1%. SonoVue is a safe transpulmonary agent and can satisfactorily improve the endocardial border delineation and show myocardial perfusion.

  3. Languaging the Borders of Europe

    Directory of Open Access Journals (Sweden)

    Olivier Kramsch

    2015-11-01

    Full Text Available Emerging from a discomfort with the blind spots encountered within and across theorizations of language and space in the field of human geography, in this article, we argue for “making space” for conceptualizations that speak from and through the everyday territories of migrants in Europe today. Inspired by a range of writers thinking postcolonially and multi/trans-lingually, the authors draw on their own embodied migrant experience to argue for re-envisioning Europe’s borders through multiple languaging practices. “Languaging”, in this view, takes linguistic practices in a migrant context as an inherently prosthetic activity, whereby any dominant, national host language is inevitably subject to the subterranean rumblings of all the languages a migrant brings with her on her global journeys. Conceived as being saturated with prosthetic “absence(s”, migrant languaging practices rework cultural geography’s bounded, inward-looking, and security-fixated understanding of the language/territory nexus, the better to open a vital space for re-envisioning language’s everyday territories as sites for translational solidarity and becoming.

  4. Borders, boundaries and desirable wishes

    Full Text Available “Borders, boundaries and desirable wishes” is the title of the residential workshop offered to a group of young adults (aged 18-25 of the Centro di Salute Mentale (Mental Health Center of the DSM Basaglia of ASL TO2 in Turin. The idea of the workshop, the definition of the objectives and the topics, which are clearly expressed in the title, come from the work of the team dedicated to group psychotherapies, which has been offering group psychodrama sessions to young adults of this age since 2008. In the delicate move to the adult age, these young adults are lost and stuck in static realities where it is not possible to open up to the dimension of desire nor to the transforming encounter with the Other, since they didn’t have the experience of boundaries and lack. These two elements are necessary to acquire the ability to make projects for oneself. During the workshop the following instruments were used: group, psychodrama and art therapy. The group, as a paternal function, ensured the presence of safe boundaries enabling individuals to experiment; psychodrama and art therapy enabled the bodies to experience encounters and transformations, using doing as a metaphor for the movement against the inhibition of doing and as a way to show oneself to the Other and be able to see the Other. 

  5. Semantic Borders and Incomplete Understanding.

    Science.gov (United States)

    Silva-Filho, Waldomiro J; Dazzani, Maria Virgínia

    2016-03-01

    In this article, we explore a fundamental issue of Cultural Psychology, that is our "capacity to make meaning", by investigating a thesis from contemporary philosophical semantics, namely, that there is a decisive relationship between language and rationality. Many philosophers think that for a person to be described as a rational agent he must understand the semantic content and meaning of the words he uses to express his intentional mental states, e.g., his beliefs and thoughts. Our argument seeks to investigate the thesis developed by Tyler Burge, according to which our mastery or understanding of the semantic content of the terms which form our beliefs and thoughts is an "incomplete understanding". To do this, we discuss, on the one hand, the general lines of anti-individualism or semantic externalism and, on the other, criticisms of the Burgean notion of incomplete understanding - one radical and the other moderate. We defend our understanding that the content of our beliefs must be described in the light of the limits and natural contingencies of our cognitive capacities and the normative nature of our rationality. At heart, anti-individualism leads us to think about the fact that we are social creatures, living in contingent situations, with important, but limited, cognitive capacities, and that we receive the main, and most important, portion of our knowledge simply from what others tell us. Finally, we conclude that this discussion may contribute to the current debate about the notion of borders.

    Primary cardiac tumors are rare. Mixomas are the most common among them; 75% are located in the left atrium, 20% in the right atrium, and the rest in the ventricles. The seldom appear in atrio-ventricular valves. Recidivant mixoma are also rare, appearing in 1-5% of all patients that have undergone surgical treatment of a mixoma. In this paper we present our experience with a female patient, who 8 years after having been operated of a left atrial mixoma, began with symptoms of mild heart failure. Transthoracic echocardiography revealed recurrence of the tumor, and was therefore subjected to a second open-heart surgery from which she recovered without complications.

    Full Text Available

    This article reflects on European borders and their everyday dynamics from a cross-border perspective. The article begins with a discussion of recent events that question current border policies in the European Union, reviews the literature on borders and border territories, and finally moves on to a discussion of the everyday effects of cross-border practices on the inhabitants of border spaces. Occasional reference is made to borders in the Americas to complete the picture of this topic. Although the issue of security is indeed relevant, we focus on the economic and social dimensions of cooperation. Three aspects are essential for border residents who attempt to use the advantages of the territories for their global nature: work, shopping, and place of residence. In conclusion, there has been a tendency toward the softening of borders and greater integration of border zones in the European Union.

    2014-01-01

    Full Text Available International borders greatly influence tourism development. In 2012 and 2013, a decline in tourists to Zimbabwe from South Africa was partially attributed to tourist border facilitation issues. It is against this background that this study sought to establish the nature of challenges faced by tourists when using the Beitbridge border post (Zimbabwean side. Questionnaire responses were thematically analysed and the study concluded that border administrative management related issues are a major barrier to tourism. Key among the study's recommendations is that the depressed tourists' border experiences obtaining at Beitbridge border post among other constraints have to be addressed as a matter of urgency. This will enhance Zimbabwe's accessibility, tourist satisfaction and the image of the country as a destination. The paper further identifies several destination managerial implications and future research priorities.

    Full Text Available Discourse theory is useful for understanding the creation of borders, whether material or imaginary. This paper addresses three situations on Mexico’s southern border between 2000 and 2015 in which elements of discourse theory may be applied. The outcomes were the following: 1 correlations may be made between the elements of the discourse moving from the northern to the southern border, but not in the opposite direction; 2 the process of securitising the discourse about migrants is continuous, and new securitising elements are regularly added; 3 an “elastic borders” phenomenon exists, where borders extend or retract, thereby creating new border regions; and 4 discourses around the southern border are constructed with more pejorative elements than the northern, despite the fact that crime rates are higher in the north.

    2015-06-01

    Full Text Available Many conservatives endorse a defence of closed borders grounded in basic liberal rights such as the basic right of association. Some conservatives also endorse libertarian principles of legitimacy. It is not clear though that this sort of defence of closed borders is somehow coherent with these libertarian ideals. I argue that conservative libertarians of this kind must reject this defence of closed borders because either it collapses into a form of statism incoherent with libertarian principles of legitimacy, or into an ideal precept without appeal regarding reality in the here and now that could only be applied to changing the very nature of the societies we know. As a result, at least conservative libertarians need to find a different source of justification for closed borders.

  19. Left atrial appendage occlusion

    2013-01-01

    Full Text Available Left atrial appendage (LAA occlusion is a treatment strategy to prevent blood clot formation in atrial appendage. Although, LAA occlusion usually was done by catheter-based techniques, especially percutaneous trans-luminal mitral commissurotomy (PTMC, it can be done during closed and open mitral valve commissurotomy (CMVC, OMVC and mitral valve replacement (MVR too. Nowadays, PTMC is performed as an optimal management of severe mitral stenosis (MS and many patients currently are treated by PTMC instead of previous surgical methods. One of the most important contraindications of PTMC is presence of clot in LAA. So, each patient who suffers of severe MS is evaluated by Trans-Esophageal Echocardiogram to rule out thrombus in LAA before PTMC. At open heart surgery, replacement of the mitral valve was performed for 49-year-old woman. Also, left atrial appendage occlusion was done during surgery. Immediately after surgery, echocardiography demonstrates an echo imitated the presence of a thrombus in left atrial appendage area, although there was not any evidence of thrombus in pre-pump TEE. We can conclude from this case report that when we suspect of thrombus of left atrial, we should obtain exact history of previous surgery of mitral valve to avoid misdiagnosis clotted LAA, instead of obliterated LAA. Consequently, it can prevent additional evaluations and treatments such as oral anticoagulation and exclusion or postponing surgeries including PTMC.

  20. Hypoplastic left heart syndrome

    2007-05-01

    Full Text Available Abstract Hypoplastic left heart syndrome(HLHS refers to the abnormal development of the left-sided cardiac structures, resulting in obstruction to blood flow from the left ventricular outflow tract. In addition, the syndrome includes underdevelopment of the left ventricle, aorta, and aortic arch, as well as mitral atresia or stenosis. HLHS has been reported to occur in approximately 0.016 to 0.036% of all live births. Newborn infants with the condition generally are born at full term and initially appear healthy. As the arterial duct closes, the systemic perfusion becomes decreased, resulting in hypoxemia, acidosis, and shock. Usually, no heart murmur, or a non-specific heart murmur, may be detected. The second heart sound is loud and single because of aortic atresia. Often the liver is enlarged secondary to congestive heart failure. The embryologic cause of the disease, as in the case of most congenital cardiac defects, is not fully known. The most useful diagnostic modality is the echocardiogram. The syndrome can be diagnosed by fetal echocardiography between 18 and 22 weeks of gestation. Differential diagnosis includes other left-sided obstructive lesions where the systemic circulation is dependent on ductal flow (critical aortic stenosis, coarctation of the aorta, interrupted aortic arch. Children with the syndrome require surgery as neonates, as they have duct-dependent systemic circulation. Currently, there are two major modalities, primary cardiac transplantation or a series of staged functionally univentricular palliations. The treatment chosen is dependent on the preference of the institution, its experience, and also preference. Although survival following initial surgical intervention has improved significantly over the last 20 years, significant mortality and morbidity are present for both surgical strategies. As a result pediatric cardiologists continue to be challenged by discussions with families regarding initial decision

    Full Text Available There are hundreds of departments and organizations working on border health issues in the California/Baja California border region trying to protect and improve health without a collaborative structure that integrates jurisdictions and organizations. As a result, there is a need to effectively improve the health in the border region by coordinating these organizations to work together and benefit from each other’s best practices. The newly developed California Border Health Collaborative (CBHC can provide the leadership and collaborative culture to positively improve the health of the border region. This article aims to describe the development process of this collaborative to include key ingredients to success, the roles of mulit-level jurisdictions, and policy implications.This article describes the methods used to develop key aspects of collaborative leadership, strategic alignment and a common vision toward the building of this collective impact approach to border health. In addition, we describe the role of key local County (County of San Diego Live Well San Diego initiative, State, (California Department of Public Health- Office of Binational Border Health, Federal (US-Mexico Border Health Commission’s Leaders across Borders, Academia (e.g., University of California San Diego and San Diego State University and non-profit entities (e.g., Project Concern International, San Ysidro Health Center in forming the BHCC. Evaluating the consortium development process included a literature review of similar processes, a review of internal documents and an analysis of developmental events. To this point the CBHC has built a strong, cohesive collaborative on the U.S. side of the border. It is sharing and leveraging local expertise to address many border health issues. Even more importantly, the BHCC has reached a key stage in which it can effectively engage its Baja California, Mexico counterparts in a manner that will prove extremely powerful

    The Radiation Safety Without Borders (RSWB) initiative provides peer support to radiation safety professionals in developing countries, which bolsters the country's infrastructure and may lead the way for IRPA Associate membership. The Health Physics Society (HPS) recognizes that many nations do not possess the infrastructure to adequately control and beneficially use ionizing radiation. In a substantial number of countries, organized radiation protection programs are minimal. The RSWB initiative relies on HPS volunteers to assist their counterparts in developing countries with emerging health physics and radiation safety programs, but whose resources are limited, to provide tools that promote and support infrastructure and help these professionals help themselves. RSWB experience to date has shown that by providing refurbished instruments, promoting visits to a HPS venue, or visiting a country just to look provide valuable technical and social infrastructure experiences often missing in the developing nation's cadre of radiation safety professionals. HPS/RSWB with the assistance of the International Atomic Energy Agency (IAEA) pairs chapters with a country, with the expectation that the country's professional radiation safety personnel will form a foreign HPS chapter, and the country eventually will become an IRPA Associate. Although still in its formative stage, RSWB nonetheless has gotten valuable information in spite of the small number of missions. The RSWB initiative continues to have significant beneficial impacts, including: Improving the radiation safety infrastructure of the countries that participate; Assisting those countries without professional radiation safety societies to form one; Strengthening the humanitarian efforts of the United States; Enhancing Homeland Security efforts through improved control of radioactive material internationally. Developing countries, including those in Latin America, underwritten by IAEA, may take advantage of resources

    2015-01-01

    Drawing upon research conducted on cross-border patients living in Laos and seeking care in Thailand, this paper examines the important role played by social networks in patients' decision-making and on the itineraries they choose to seek treatment on the Thai side of the border. Due to the vastly contrasting situations between the two countries in terms of healthcare supply, and considering Laotians' increasing demand for high quality healthcare, a number of them have managed to satisfy their needs by combining cross-border treatment with the use of the healthcare facilities provided by their own country. This study consisted first of household surveys conducted in five border areas (2006-2007) in Laos in order to quantify and map out cross-border healthcare-related travel patterns. Afterwards, interviews were conducted with cross-border patients (55), Laotian and Thai medical doctors (6), Thai social workers (5), and officials working in public institutions (12). While socioeconomic and spatial factors partly explain cross-border mobility, patients' social networks significantly influence treatment itineraries throughout the decision-making process, including logistical and financial considerations. The social networks existing at different geographical levels (neighbourhood, regional and global) are therefore a powerful analytical tool not only for understanding the emergence of these cross-border movements but also for justifying them in an authoritarian political environment such as Lao PDR's.

  9. Border regions as the tourist destination

    Majstorović Vukica

    2013-01-01

    Full Text Available Tourism, as a global phenomenon, has found its place in every corner of the world. During a certain period of time, the tourism market has become saturated by mass tourism causing the creation of new attractive destinations for tourists. Thus, some of the border areas in the world attract and keep passers-by while transforming into the new tourist destinations. In this paper, it is possible to see relations and interconnections between tourism and international boundaries. Tourism in border regions has an opportunity to activate these areas that are often neglected by the state. Some European countries have taken advantage of this opportunity and they improved their tourism industry by developing their border regions. This kind of tourism development can be applied in Serbia and, in that way, activate the border areas of our country. However, in order to develop tourism in these areas, it is necessary to have an adequate international cooperation between two or more states. This can be achieved by various instruments of cross-border cooperation in tourism through the engagement of neighbouring countries in joint plans and cooperation.

    The author demonstrates the Border Trade Facilitation System (BTFS), an agent-based bilingual e-commerce system built to expedite the regulation, control, and execution of commercial trans-border shipments during the delivery phase. The system was built to serve maquila industries at the US/Mexican border. The BTFS uses foundation technology developed here at Sandia Laboratories' Advanced Information Systems Lab (AISL), including a distributed object substrate, a general-purpose agent development framework, dynamically generated agent-human interaction via the World-Wide Web, and a collaborative agent architecture. This technology is also the substrate for the Multi-Agent Simulation Management System (MASMAS) proposed for demonstration at this conference. The BTFS executes authenticated transactions among agents performing open trading over the Internet. With the BTFS in place, one could conduct secure international transactions from any site with an Internet connection and a web browser. The BTFS is currently being evaluated for commercialization.

    Full Text Available This paper studies the possible impacts of liquefied natural gas (LNG projects on natural gas prices on both sides of the U. S.-Mexico border in California. In that state gas prices are high and demand is expected to grow. Several projects for LNG facilities have been proposed and have to cope with public opinions against them. In Baja California, four LNG projects are under development given the rising demand forecasted for the next years. After a detailed study of the opportunity for LNG projects, we conclude with an analysis of the fundamentals of the current and future price formation in both sides of the U. S.- Mexico border.

    "Meteors Without Borders" is a global project, organized by Astronomers Without Borders and launched during the Global Astronomy Month in 2010 for the Lyrid meteor shower. The project focused on encouraging amateur astronomy groups to hold public outreach events for major meteor showers, conduct meteor-related classroom activities, photography, poetry and art work. It also uses social-media platforms to connect groups around the world to share their observations and photography, live during the events. At the International Meteor Conference 2011, the progress of the project was presented along with an extended invitation for collaborations for further improvements of the project.

  19. Crossing the Borders: An Eco-cinecritical Analysis of Plant Wars and Bird Without Borders

    Directory of Open Access Journals (Sweden)

    Hsiao-Ching Li

    2011-01-01

    Full Text Available This essay reads two Asian nature-oriented films from the perspective of ecocinecriticism,an ecologically minded film criticism. Plant Wars, produced by PTSTaiwan, questions the demarcation between native plants and exotic plants as well asbetween plants and human beings so as to remap the in-between border area. Thestorytelling method it applies is to feature 14 currently native plants as the maincharacters, and illustrates their relationship to aboriginal people, farmers, beekeepersand to other insect species. Bird Without Borders, also produced by PTS, tells the storyof the migration journey of a group of black-faced spoonbills flying 16,000 kilometersall the way from Tainan, Taiwan, to Japan, along the border of South and North Korea,to a remote island of China to look for feeding places and then back to Taiwan to spendthe winter. Different layers of border-crossing are shown in Bird. One similarity ofthese two PTS productions is the search for border-crossing so as to redefine or revisewhat the border means. Plant questions the biological categorization of the native plantsand the exotic plants; Bird illustrates how the crew physically follows the route of thebirds’ flight which crosses the national borders to provide a vision of remapping thenatural territory through challenging the idea of a fixed “place.” Both are seeking forways to trespass the man-made borders: Plant via environmental imagination; Bird viasome physical movement. While the title of Plant Wars seemingly expresses its positionmore strongly through “wars,” Bird Without Borders explicitly asserts a dream of noborders.

  20. The border zone of the early myocardial infarction in dogs; its characteristics and viability.

    In open-chest dogs, the left anterior descending coronary artery was ligated for 150 min. The heart was semiserially cut on a cryomicrotome and areas of ischemic damage were visualized by means of glycogen depletion (PAS reaction) and tissue acidosis (a "sandwich" technique with pH indicator dispersed in a layer of gel). The extent of myocardial damage was determined morphometrically. The mass of the glycogen-depleted heart muscle was greater than the mass of the ischemic tissue detected by means of decreased pH (p less than 0.01). The border zone was characterized by glycogen depletion without acidosis. Circulation studies using intravital fluorescein staining have shown that perfusion is partially retained in the border zone; it is assumed that the hypoperfusion triggers glycogenolysis. Nevertheless, the level of perfusion suffices to wash out the acidic end products. Comparison of contrapulsation-treated dogs and untreated dogs shows that the amount of damaged tissue comprising the border zone can be reduced by this therapeutic intervention (p less than 0.02) - in contrast to the acidotic tissue, the amount of which is not significantly influenced. Therefore the border zone contains damaged but still viable muscle cells.

  1. Alcohol-related social problems among Mexican Americans living in U.S.-Mexico border and non-border areas.

    2012-08-01

    This paper examines alcohol-related social problems among Mexican Americans living along the U.S.-Mexico border and in non-border areas. Interviews were conducted among Mexican Americans in the border regions of California, Arizona, New Mexico, and Texas (N=1307). Non-border respondents were interviewed primarily in Houston and Los Angeles (N=1288) as part of the Hispanic Americans Baseline Alcohol Survey (HABLAS). Both the border and HABLAS surveys employed multistage cluster sample designs (response rates were 67% and 76%, respectively). In the bivariate analysis, there were no significant differences between border and non-border areas in the proportion of those with one or more social problem. In non-border areas, the prevalence of alcohol problems did not differ significantly by age. However, along the border the prevalence of alcohol problems was significantly different across age groups, with 18 to 29year old men and women having the highest prevalence. The final models showed no residence effect on problem likelihood. Drinking was strongly associated with problems. Although young border residents had higher problem prevalence rates than older residents, the logistic regression models showed no effect of border residence on the likelihood of problems, indicating that problems are due to alcohol consumption, not the border environment. The border, however, did appear to influence more drinking among young people. Regardless of residence, alcohol treatment and preventive interventions tailored to Mexican Americans are essential and special attention should be focused on younger individuals near the border.

    The question of why Dora left her treatment before it was brought to a satisfactory end and the equally important question of why Freud chose to publish this problematic and fragmentary story have both been dealt with at great length by Freud’s successors. Dora has been read by analysts, literary...... critics, and not least by feminists. The aim of this paper is to point out the position Freud took toward his patient. Dora stands out as the one case among Freud’s 5 great case stories that has a female protagonist, and reading the case it becomes clear that Freud stumbled because of an unresolved...... problem toward femininity, both Dora’s and his own. In Dora, it is argued, Freud took a new stance toward the object of his investigation, speaking from the position of the master. Freud presents himself as the one who knows, in great contrast to the position he takes when unraveling the dream. Here he...

  14. Spanning National Borders: Split Lives of Croatian Migrant Families

    Directory of Open Access Journals (Sweden)

    Jasna Čapo Žmegač

    2007-06-01

    Full Text Available Using the ethnographic approach, the article describes three modalities of family arrangements practiced by Croatian migrants in Germany over the past thirty years. In all three, family members were divided between two localities in physical space, which were situated in different states – Croatia or Bosnia-Herzegovina and Germany: in one case only the father was a migrant while his wife and children stayed in the native country; in another the couple left for Germany leaving the child in Croatia; in the third the couple lived with some of their children in Germany while other children were living in Croatia. Some of these families were dispersed across international borders during the entire life and migration course (thirty years or more, while some experienced shorter or longer periods of separation followed by reunion of all or some family members, who crossed borders in one or another direction. It follows from this presentation that, rather than being a temporary phase aimed at reintegration of the family at a higher economic level, bilocality, viewed from a diachronic perspective, is a more or less continuous family arrangement and a way of life of migrant families. The question remains open as to whether transnational families are units in which emotional ties and closeness between its members are maintained. The data might point in this direction but might also lead to a hypothesis that, precisely because it is dispersed across long distances, the family needs to construct its unity (emotional if not physical and therefore narratively presents itself as integrated and reconfigured.

  19. Grandparenting across borders: American grandparents and their Israeli grandchildren in a transnational reality.

    Science.gov (United States)

    Sigad, Laura I; Eisikovits, Rivka A

    2013-12-01

    Families are increasingly dispersed across national borders. Americans in Israel are one migrant group that represents the worldwide phenomenon of transnationalism. Grandparents separated geographically from their grandchildren develop new means of communication with them and new kinds of relationships. This study uses ethnographic interviews with the grandparents of transnational, American-Israeli children and youth to offer an in-depth examination of the experience of grandparenting across borders. We find that grandparenting children who are both geographically distant and raised in a foreign culture necessitates the development of new ways of maintaining relationships with grandchildren. This study considers the impact of transnational migration on the extended family, on those left behind, who struggle with redefining their roles as grandparents and with the sense of being deprived of the roles they had expected to play.

  20. Hmong Across Borders or Borders Across Hmong? Social and Political Influences Upon Hmong People

    Directory of Open Access Journals (Sweden)

    Prasit Leepreecha

    2014-12-01

    Full Text Available The Hmong are a transnational ethnic people, because of their dispersal from China into Southeast Asia in the early 19th century and from Southeast Asia to Western countries from 1975 onward. However, even within the context of Southeast Asia and southern China, the Hmong are a transnational ethnic group, due to state boundaries and the enforcement of international laws.Scholars speak as though the Hmong population has crossed political and legal borders by their movement across state boundaries and international borders. However, I argue that it is the political, social, and legal borders that have cut across the Hmong people and subjected them to be citizens of different modern nation-states. Even in the present time, these borders still, and continuously, play important roles that cross and divide the Hmong people into distinctive subgroups and fragments. In this article, I will start by describing the generally understood situation of Hmong being across national borders, and then will explain my argument that borders are across the Hmong.

    Engel and Rogers (1996) find that crossing the US-Canada border can considerably raise relative price volatility and that exchange rate fluctuations explain about one-third of the volatility increase. In reevaluating the border effect, this study shows that cross-country heterogeneity in price volatility can lead to significant bias in measuring the border effect unless proper adjustment is made to correct it. The analysis explores the implication of symmetric sampling for border effect estim...

  5. Non-compact left ventricle/hypertrabeculated left ventricle

    International Nuclear Information System (INIS)

    Restrepo, Gustavo; Castano, Rafael; Marmol, Alejandro

    2005-01-01

    Non-compact left ventricle/hypertrabeculated left ventricle is a myocardiopatie produced by an arrest of the normal left ventricular compaction process during the early embryogenesis. It is associated to cardiac anomalies (congenital cardiopaties) as well as to extracardial conditions (neurological, facial, hematologic, cutaneous, skeletal and endocrinological anomalies). This entity is frequently unnoticed, being diagnosed only in centers with great experience in the diagnosis and treatment of myocardiopathies. Many cases of non-compact left ventricle have been initially misdiagnosed as hypertrophic myocardiopatie, endocardial fibroelastosis, dilated cardiomyopatie, restrictive cardiomyopathy and endocardial fibrosis. It is reported the case of a 74 years old man with a history of chronic arterial hypertension and diabetes mellitus, prechordial chest pain and mild dyspnoea. An echocardiogram showed signs of non-compact left ventricle with prominent trabeculations and deep inter-trabecular recesses involving left ventricular apical segment and extending to the lateral and inferior walls. Literature on this topic is reviewed

    2010-01-01

    Hand dominance is defined as a proneness to use one hand rather than another in performing the majority of activities and this is the most obvious example of cerebral lateralization and an exclusive human characteristic. Left-handed people comprise 6-14% of the total population, while in Serbia, this percentage is 5-10%, moving from undeveloped to developed environments, where a socio-cultural pressure is less present. There is no agreement between investigators who in fact may be considered a left-handed person, about the percentage of left-handers in the population and about the etiology of left-handedness. In the scientific literature left-handedness has been related to health disorders (spine deformities, immunological disorders, migraine, neurosis, depressive psychosis, schizophrenia, insomnia, homosexuality, diabetes mellitus, arterial hypertension, sleep apnea, enuresis nocturna and Down Syndrome), developmental disorders (autism, dislexia and sttutering) and traumatism. The most reliable scientific evidences have been published about the relationship between left-handedness and spinal deformities in school children in puberty and with traumatism in general population. The controversy of other results in up-to-now investigations of health aspects of left-handedness may partly be explained by a scientific disagreement whether writing with the left hand is a sufficient criterium for left-handedness, or is it necessary to investigate other parameters for laterality assessment. Explanation of health aspects of left-handedness is dominantly based on Geschwind-Galaburda model about "anomalous" cerebral domination, as a consequence of hormonal disbalance.

After controlling for distance and country size, we find that relative to state-to-state trade, crossing ...

  19. The Nature and Functions of European Political Borders

    Directory of Open Access Journals (Sweden)

    Jernej Zupančič

    2008-07-01

    Full Text Available The political border limits a state’s territory and symbolizes the extent of a state’s power and ownership. Borders give integrity to the inner state territory which they enclose (the role of establishing national integrity and at the same time form an outer boundary segregating the state territory from the surrounding politicial entities (the segregation role. European borders are old and reflect the political history of an old continent. The last major border changes happened after World War II. Over the centuries borders were merely lines separating one territory from another. Such borders were understood as »frontiers«. Forming an effective barrier against enemies was the overriding function of borders. Many borders were fortified and further enhanced by means of various defensive systems. In the second half of the 20th century the character of political borders changed. They became a contact area between countries, nations and cultures. Contemporary European borders reflect the colourful history of an old continent. They are predominantely functional markers: they represent the political and juridical delimitation of territories, they mark economic barriers and show their defensive nature and reveal the extent of cultural contact. As a result of European integration processes, the nature of political borders has changed: instead of division, their integration role is brought to the fore. A united Europe is nevertheless still not a borderless Europe! The borders within the »Schengen-area« have retained their political and administrative functions, it is just that the customs and security checks at the borders have been removed. During the period of European integration, borderlines were stabilized in accordance with the 1974 Helsinki Agreement. But despite this we can still observe ongoing changes to state borders, particularly in areas of conflict such as the Balkan peninsula. It seems after all that the process of demarcation

  1. Opportunities for Cross-Border Entrepreneurship Development in a Cluster Model Exemplified by the Polish–Czech Border Region

    Directory of Open Access Journals (Sweden)

    Joanna Kurowska-Pysz

    2016-03-01

    Full Text Available The subject of the paper is the analysis and evaluation of cross-border entrepreneurship development opportunities on the basis of cross-border cooperation, which has gradually evolved from consisting of bilateral partnerships to a networking model or even a cluster. The study conducted at the Polish–Czech border area indicates that, in terms of the development of cross-border cooperation, the economic sphere is lagging far behind social activities such as culture, education and tourism. At the same time, Polish and Czech enterprises are not sufficiently mobilized to develop cross-border entrepreneurship, although a number of support instruments in this regard have been proposed. Sustainable development of the border should take into account both social and economic aspects. An important research problem therefore becomes determining the possibility of boosting the development of cross-border entrepreneurship on the basis of the existing forms of cross-border cooperation, including cooperation in the social sphere. The aim of this paper is to define the conditions and opportunities for the development of cluster cooperation in the area of cross-border entrepreneurship. The author has attempted to resolve whether the intensity of cross-border cooperation can be a factor which mobilizes companies to develop their cross-border entrepreneurship and whether cross-border entrepreneurship can be further developed within the cluster model.

    A two-year old, male entire Border collie was presented with a one-year history of exercise-induced collapsing on the pelvic limbs. Physical examination revealed generalised muscle atrophy. Neurological examination supported a generalised neuromuscular disorder. Electromyography revealed spontaneous electrical activity in almost all muscles. Unfixed and formaldehyde-fixed biopsy samples were collected from the triceps brachii, longissimus and vastus lateralis muscles. Histopathological, histochemical and ultrastructural examinations of biopsy specimens were consistent with either centronuclear or myotubular myopathy. The dog clinically improved with supportive treatment with L-carnitine, co-enzyme Q10 and vitamin B compound. To the authors' knowledge, this is the first report of centronuclear/myotubular myopathy in a Border collie. © 2012 British Small Animal Veterinary Association.

    Border interactions have reached unprecedented levels in recent decades, not only due to their potential for territorial integration but also considering their role in supranational processes, such as landscape reclamation, infrastructure development and land use planning on European territory. In this scenario, successful examples related to the redevelopment of degraded areas have been showing positive impacts at several levels, such as the social, economic, environmental and aesthetic ones which have ultimately related this process, positively, to sustainability issues. However, concerning to border areas, and due to their inherent legislative and bureaucratic conflicts, the intervention in these areas is more complex. Still, and taking into account previously developed projects and strategies of cross-border cooperation (CBC) in European territory it is possible to identified that the definition of common master plans and common objectives are critical issues to achieve the desired territorial success. Additionally, recent studies have put forward some noteworthy ideas highlighting that it is possible to establish a positive correlation between CBC processes and an increasing redevelopment of degraded border areas, with special focus on the reclamation of derelict landscapes fostering soil reuse and redevelopment. The present research, throughout case study analysis at the Mediterranean level - considering case studies from Portugal, Spain, Monaco and Italy - which presents specific data on border landscape redevelopment, enables us to conclude that CBC processes have a positive influence on the potential redevelopment of degraded border areas, considering not only urban but also rural land. Furthermore, this paper presents data obtained through a public participation process which highlights that these areas present a greater potential for landscape reclamation, fostering resource sustainability and sustainable growth.

  14. Cross-border ties and self-rated health status for young Latino adults in Southern California.

    Torres, Jacqueline M

    2013-03-01

    At the same time that health researchers have mostly ignored the cross-border nature of immigrant social networks, scholars of immigrant "transnationalism" have left health largely unexamined. This paper addresses this gap by analyzing the relationship between cross-border ties and self-rated health status for young Latino adults living in the greater Los Angeles area (n = 1268). Findings based on an ordered logistic regression analysis suggest that cross-border relationships may have both protective and adverse effects on overall health status. Specifically, those reporting a period of extended parental cross-border separation during childhood have lower odds of reporting better categories of self-rated health, all else equal. Conversely, a significant positive association was found between having a close relative living abroad and self-rated health status for foreign-born respondents when interacted with immigrant generation (foreign versus U.S.-born). Given the findings of significant negative and positive relationships between cross-border ties and self-rated general health status, I discuss the implications for future research on the social determinants of immigrant health.

  15. Changing European borders: from separation to interface? An introduction

    Directory of Open Access Journals (Sweden)

    Jen Nelles

    2011-03-01

    Full Text Available The aim of this special issue is to address the evolution of European borders from a comparative perspective. This collection of papers spans a wide variety of topics in the realm of borderland studies. Although each engages with a single empirical or theoretical case collectively they identify nuances relevant to the theoretical elaboration of borders, and particularly contribute to the field of sub-national cross-border cooperation. In the course of its analysis each paper contributes to a broader understanding of the definition of cross-border regions; identifies a set of barriers to cooperation in these contexts; explores the role of identities on cooperation and of the role of borders in constructing those identities; and reflects on the socio-political meanings and uses of these international boundaries. This introduction discusses theoretical significance of these contributions to major debates in the study of borders and border regions.

    Full Text Available Polish and Russian cross-border cooperation is governed by lawful agreements. The enlargement of the Schengen Area had a significant impact on Kaliningrad Oblast relations and cross-border cooperation with its neighbours. The introduction of visas between Poland and Russia hindered and restricted local border trade which had for years been the only measure mitigating social and economic problems of the cross-border regions. Nevertheless, border traffic between Poland and Kaliningrad grew steadily, to exceed four million in 2012.

  5. Left-handedness and health

    2010-01-01

    Full Text Available Hand dominance is defined as a proneness to use one hand rather than another in performing the majority of activities and this is the most obvious example of cerebral lateralization and an exclusive human characteristic. Left-handed people comprise 6-14% of the total population, while in Serbia, this percentage is 5-10%, moving from undeveloped to developed environments, where a socio-cultural pressure is less present. There is no agreement between investigators who in fact may be considered a left-handed person, about the percentage of left-handers in the population and about the etiology of left-handedness. In the scientific literature left-handedness has been related to health disorders (spine deformities, immunological disorders, migraine, neurosis, depressive psychosis, schizophrenia, insomnia, homosexuality, diabetes mellitus, arterial hypertension, sleep apnea, enuresis nocturna and Down Syndrome, developmental disorders (autism, dislexia and sttutering and traumatism. The most reliable scientific evidences have been published about the relationship between left-handedness and spinal deformities in school children in puberty and with traumatism in general population. The controversy of other results in up-to-now investigations of health aspects of left-handedness may partly be explained by a scientific disagreement whether writing with the left hand is a sufficient criterium for left-handedness, or is it necessary to investigate other parameters for laterality assessment. Explanation of health aspects of left-handedness is dominantly based on Geschwind-Galaburda model about 'anomalous' cerebral domination, as a consequence of hormonal disbalance. .

  6. Left ventricular wall stress compendium.

    Zhong, L; Ghista, D N; Tan, R S

    2012-01-01

    Left ventricular (LV) wall stress has intrigued scientists and cardiologists since the time of Lame and Laplace in 1800s. The left ventricle is an intriguing organ structure, whose intrinsic design enables it to fill and contract. The development of wall stress is intriguing to cardiologists and biomedical engineers. The role of left ventricle wall stress in cardiac perfusion and pumping as well as in cardiac pathophysiology is a relatively unexplored phenomenon. But even for us to assess this role, we first need accurate determination of in vivo wall stress. However, at this point, 150 years after Lame estimated left ventricle wall stress using the elasticity theory, we are still in the exploratory stage of (i) developing left ventricle models that properly represent left ventricle anatomy and physiology and (ii) obtaining data on left ventricle dynamics. In this paper, we are responding to the need for a comprehensive survey of left ventricle wall stress models, their mechanics, stress computation and results. We have provided herein a compendium of major type of wall stress models: thin-wall models based on the Laplace law, thick-wall shell models, elasticity theory model, thick-wall large deformation models and finite element models. We have compared the mean stress values of these models as well as the variation of stress across the wall. All of the thin-wall and thick-wall shell models are based on idealised ellipsoidal and spherical geometries. However, the elasticity model's shape can vary through the cycle, to simulate the more ellipsoidal shape of the left ventricle in the systolic phase. The finite element models have more representative geometries, but are generally based on animal data, which limits their medical relevance. This paper can enable readers to obtain a comprehensive perspective of left ventricle wall stress models, of how to employ them to determine wall stresses, and be cognizant of the assumptions involved in the use of specific models.

  7. Borders as membranes :metaphors and models for improved policy in border regions.

    2005-10-01

    Political borders are controversial and contested spaces. In an attempt to better understand movement along and through political borders, this project applied the metaphor of a membrane to look at how people, ideas, and things ''move'' through a border. More specifically, the research team employed this metaphor in a system dynamics framework to construct a computer model to assess legal and illegal migration on the US-Mexico border. Employing a metaphor can be helpful, as it was in this project, to gain different perspectives on a complex system. In addition to the metaphor, the multidisciplinary team utilized an array of methods to gather data including traditional literature searches, an experts workshop, a focus group, interviews, and culling expertise from the individuals on the research team. Results from the qualitative efforts revealed strong social as well as economic drivers that motivate individuals to cross the border legally. Based on the information gathered, the team concluded that legal migration dynamics were of a scope we did not want to consider hence, available demographic models sufficiently capture migration at the local level. Results from both the quantitative and qualitative data searches were used to modify a 1977 border model to demonstrate the dynamic nature of illegal migration. Model runs reveal that current US-policies based on neo-classic economic theory have proven ineffective in curbing illegal migration, and that proposed enforcement policies are also likely to be ineffective. We suggest, based on model results, that improvement in economic conditions within Mexico may have the biggest impact on illegal migration to the U.S. The modeling also supports the views expressed in the current literature suggesting that demographic and economic changes within Mexico are likely to slow illegal migration by 2060 with no special interventions made by either government.

  8. Smart border initiative: a Franco-German cross-border energy optimisation project

    International Nuclear Information System (INIS)

    2017-01-01

    Integrated and optimised local energy systems will play a key role in achieving the energy transition objectives set by France and Germany, in line with the Energy Union's goals, and contribute to ensuring a secure, affordable and climate-friendly energy supply in the EU. In order to capitalise on the French and German expertise and experiences in developing such systems and to continue strengthening the cross-border cooperation towards a fully integrated European energy market, both Governments have decided to launch a common initiative to identify and structure a cross-border energy optimisation project. Tilia and Dena have undertaken this mission to jointly develop the Smart Border Initiative (SBI). The SBI will, on the one hand, connect policies designed by France and Germany in order to support their cities and territories in their energy transition strategies and European market integration. It is currently a paradox that, though more balanced and resilient energy systems build up, bottom-up, at the local level, borders remain an obstacle to this local integration, in spite of the numerous complementarities observed in cross-border regions, and of their specific needs, in terms of smart mobility for example. The SBI project aims at enabling European neighbouring regions separated by a border to jointly build up optimised local energy systems, and jointly develop their local economies following an integrated, sustainable and low-carbon model. On the other hand, this showcase project will initiate a new stage in the EU electricity market integration, by completing high voltage interconnections with local, low voltage integration at DSO level, opening new optimisation possibilities in managing the electricity balance, and enabling DSOs to jointly overcome some of the current challenges, notably the increased share of renewable energy (RE) and ensuring Europe's security of supply

  9. Cross-border policy effects on alcohol outcomes: drinking without thinking on the u.s.-Mexico border?

    Science.gov (United States)

    Mills, Britain A; Caetano, Raul; Vaeth, Patrice

    2014-11-01

    Rates of alcohol-related outcomes are sensitive to policy differences in politically distinct, adjacent territories. Factors that shape these cross-border effects, particularly when the policy differences are longstanding, remain poorly understood. We compared the ability of 2 classes of variables with theoretical relevance to the U.S.-Mexico border context-bar attendance and alcohol-related social-cognitive variables-to explain elevated drinking on the U.S. side of the border relative to other areas of the United States. Data were collected from multistage cluster samples of adult Mexican Americans on and off the U.S.-Mexico border (current drinker N = 1,351). Structural equation models were used to test drinking context (frequency of bar attendance) and 6 different social-cognitive variables (including alcohol-related attitudes, norms, motives, and beliefs) as mediators of border effects on a composite drinking index. The border effect on drinking varied by age (with younger adults showing a stronger effect), consistent with previous findings and known risk factors in the region. Contrary to theoretical expectations, 6 different social-cognitive variables-despite relating strongly with drinking-were comparable in border and nonborder areas (within and across age) and played no role in elevated drinking on the border. Conversely, elevated drinking among border youth was mediated by bar attendance. This mediated moderation effect held after adjusting for potential sociodemographic and neighborhood-level confounders. Increased drinking among U.S.-Mexico border youth is explained by patterns of bar attendance, but not by more permissive alcohol-related social-cognitive variables in border areas: Border youth attend bars and drink more than their nonborder counterparts, despite having comparable alcohol-related beliefs, attitudes, norms, and motives for use. Alcohol's heightened availability and visibility on both sides of the border may create opportunities for

    Full Text Available Although literature and poetry have numerous borders of their own,these are rarely assumed to have any significance for the world out-side the text itself. A number of reasons for this distinctive division certainly stem from the literary field itself. This paper intends to indicate the exclusivist stance of some theories of literature, and the inclucivist of others, before exploring the possibilities of bridging between borders in text and territory by reference to the life and literature of Oscar Wilde and a performative and imaginative analysis of Paul Muldoon's epigrammatic poem The Plot.

    Full Text Available This paper considers the seismicity of Southern Scotland and Northern England up to the year 1750. This area was formerly a border area between two states that eventually became politically united. Much of the area is uplands, and the seismicity is moderate to low. This makes for some problems in studying historical seismicity, yet the area provides a number of case studies of general interest in the field of historical seismology, including a rare case of being able to track down a «missing» earthquake.

  12. Algeria Post Arab Spring : The Forced Virtualisation of the Borders

    Directory of Open Access Journals (Sweden)

    Louisa Dris-Aït Hamadouche

    2016-06-01

    Full Text Available Algeria is the core of the Maghreb and shares land borders with seven countries Maghreb and Sahel countries. However, since 2011, none of the seven land borders is stable and se-cure. So, even if Algeria is considered as a stable country, this stability is fragile and is likely to be more precarious if the country has to face simultaneously an economic crisis and deli-cate presidential succession. Domestic incertitude coupled to regional conflicts puts the Algerian borders under unprecedented pressure. Consequently, almost all the governmental declarations expressed worries about the vulnerability of the borders, and assurances about the security services determination to assure the state security. However, to what extant this promise can be entirely fulfilled, regarding the borders’ characteristics and the specificity of the context? Why is the virtualization of the borders forced? As regards to the growing per-meability of the borders, can their militarization guarantee their security?

  13. Comparative balance of border regulations in four neighboring Caribbean countries

    Directory of Open Access Journals (Sweden)

    Silvia Cristina Mantilla Valbuena

    2016-07-01

    Full Text Available This article seeks to investigate whether there is a potential for border integration among four adjoining Caribbean countries: Colombia, Nicaragua, Panama and Costa Rica. The discussion is part of the “cross-border” concept and the integration of subnational entities in two or more nation states, with particular emphasis on the role played by the societies that inhabit border regions. A comparative analysis model is used to assess border regulations in each country’s various territorial levels based on relevant legal elements, autonomous processes and decentralization. The article concludes that the more modern each country’s border regulations and constitutional, political and administrative reforms are, the greater the likelihood of cross-border integration. Colombia and Nicaragua have the highest potential for integrating their borders, whereas Panama and Costa Rica have the lowest potential.

  14. Picking and Choosing the ‘Sovereign’Border

    DEFF Research Database (Denmark)

    Parker, Noel; Adler-Nissen, Rebecca

    2012-01-01

    We argue that the continued persistence of borders is an effect of their constitutive role for the many dimensions of a social particular. States cannot choose to have a border; but they can and do make choices amongst the materials available on the various planes of inscription for bordering....... For contemporary states the planes have become increasingly disaggregated, in the sense that they do not fall into place at one and the same border. Thus, states have to pick and choose different articulations (often inconsistently) on different planes. We illustrate these ideas with instances, present......-day and historical, of bordering. A corollary of there being more need to pick and choose is that articulations of sovereignty change. So, sovereignty is increasingly the material of ‘sovereignty games’, where sovereignty is used as a political instrument. In sum, our theory directs attention to state bordering...

    Collins-Dogrul, Julie

    2006-12-01

    During World War II Mexican and US health professionals and organizations constructed a transnational organizational field to manage the border's public health problems. Despite barriers to inter-organizational cooperation, including disparate administrative structures and North-South stratification, the field's transnational approach to health on the border has continued for 60 years. Using archival data to track changes in the number and types of organizations, this article argues that the field practitioners call "border health" reconfigured during the North American Free Trade Association (NAFTA) decade from an era of loosely organized professionals to a specialized bureaucracies era. This change brought new vitality to border health, with transnational ties increasing and diversifying, but has not weakened entrenched cross-border inequalities. The organizational history of the US-Mexico border health field demonstrates how macro-politics and inter-organizational stratification shape transnational public health problems.

  16. Temporary reintroduction of border controls at French borders inside the Schengen Area

    CERN Multimedia

    2015-01-01

    The French authorities have informed CERN that, in view of the upcoming COP21 Paris Climate Conference, France will exceptionally reintroduce controls at its borders with Schengen states for one month from 13 November to 13 December 2015. All border posts and crossing points between France and Switzerland will be affected by this measure.   Members of the personnel are therefore reminded that, when crossing borders within the Schengen Area*, they must carry: either, in the case of citizens of European Economic Area (EEA) countries and Switzerland, an official identity document (identity card or passport); or, in the case of non-EEA and non-Swiss citizens, an identity document together with a Schengen visa if they are subject to this obligation, or an identity document together with a residence permit issued by a Schengen state** if they have one.   The French authorities will make every effort to limit the impact of this measure on cross-border traffic, and wish to thank the members of th...

  17. Left main percutaneous coronary intervention.

    Science.gov (United States)

    Teirstein, Paul S; Price, Matthew J

    2012-10-23

    The introduction of drug-eluting stents and advances in catheter techniques have led to increasing acceptance of percutaneous coronary intervention (PCI) as a viable alternative to coronary artery bypass graft (CABG) for unprotected left main disease. Current guidelines state that it is reasonable to consider unprotected left main PCI in patients with low to intermediate anatomic complexity who are at increased surgical risk. Data from randomized trials involving patients who are candidates for either treatment strategy provide novel insight into the relative safety and efficacy of PCI for this lesion subset. Herein, we review the current data comparing PCI with CABG for left main disease, summarize recent guideline recommendations, and provide an update on technical considerations that may optimize clinical outcomes in left main PCI.

    Algeria is the core of the Maghreb and shares land borders with seven countries Maghreb and Sahel countries. However, since 2011, none of the seven land borders is stable and se-cure. So, even if Algeria is considered as a stable country, this stability is fragile and is likely to be more precarious if the country has to face simultaneously an economic crisis and deli-cate presidential succession. Domestic incertitude coupled to regional conflicts puts the Algerian borders under unprecedented...

    Accordingly, it is necessary to work out a proper independent regional policy of economic cross-border cooperation development that will define a strategy for border regions development and cross-border cooperation across the whole state border. In the process of implementation this policy should include programme development that will provide for the use of opportunities of cross-border cooperation for increase of living standards of border regions by forming of integrated cross-border economic space of Ukraine.

  2. Apraxia in left-handers.

    Science.gov (United States)

    Goldenberg, Georg

    2013-08-01

    In typical right-handed patients both apraxia and aphasia are caused by damage to the left hemisphere, which also controls the dominant right hand. In left-handed subjects the lateralities of language and of control of the dominant hand can dissociate. This permits disentangling the association of apraxia with aphasia from that with handedness. Pantomime of tool use, actual tool use and imitation of meaningless hand and finger postures were examined in 50 consecutive left-handed subjects with unilateral hemisphere lesions. There were three aphasic patients with pervasive apraxia caused by left-sided lesions. As the dominant hand is controlled by the right hemisphere, they constitute dissociations of apraxia from handedness. Conversely there were also three patients with pervasive apraxia caused by right brain lesions without aphasia. They constitute dissociations of apraxia from aphasia. Across the whole group of patients dissociations from handedness and from aphasia were observed for all manifestations of apraxia, but their frequency depended on the type of apraxia. Defective pantomime and defective tool use occurred rarely without aphasia, whereas defective imitation of hand, but not finger, postures was more frequent after right than left brain damage. The higher incidence of defective imitation of hand postures in right brain damage was mainly due to patients who had also hemi-neglect. This interaction alerts to the possibility that the association of right hemisphere damage with apraxia has to do with spatial aptitudes of the right hemisphere rather than with its control of the dominant left hand. Comparison with data from right-handed patients showed no differences between the severity of apraxia for imitation of hand or finger postures, but impairment on pantomime of tool use was milder in apraxic left-handers than in apraxic right-handers. This alleviation of the severity of apraxia corresponded with a similar alleviation of the severity of aphasia as

    The transient left ventricular apical ballooning syndrome, also known as Takotsubo cardiomyopathy, is characterized by transient left ventricular dysfunction in the absence of obstructive epicardial coronary disease. Although the syndrome has been reported in Japan since 1990, it is rare in other regions. Rapid recognition of the syndrome can modify the diagnostic and therapeutic attitude i.e. avoiding thrombolysis and performing catheterization in the acute phase. (author)

  4. First Philosophy in the Border Zone

    Viggo Rossvaer

    2016-09-01

    Full Text Available The article will be devoted to such problems as a idea of subsidiarity, a cosmopolitan right and a visitor figure in context and interpretation of ancient and modern philosophy. The article deals with the concept of subsidiarity which is taken as a point of departure for the discipline of borderology, an academic study with Kantian roots. Borderology, according to the principle of subsidiarity, can present as a new field of investigation which invites philosophers and social scientists to replace a “top down” with a “bottom up” procedure. The figure of the visitor is close linked with the experience of subsidiarity which means the freedom and initiative below the level of State. In Immanuel Kant’s strategy for perpetual peace, the figure of the visitor launches a critique of a tendency to self-aggrandizement, characteristic of the modern State and thereby a defense of the political independence of local border regions. The visitor also invites us to see, think and work to liberate our own subjectivity from false voices of sovereignty. Kant articulates the offer of the visitor by bringing in the term Verkehr. Using Kant scholar Otfried Höffe,s methodology we show how idea of subsidiarity is overlooked in international political theory, explain some constitutive principles of borderology, from which is more important is the methodological principle of an intercultural discourse and presents borderology as an anti-Huntingtonian model for border studies.

  5. Left Main Coronary Artery Aneurysm

    Full Text Available Aneurysms of the left main coronary artery are exceedingly rare clinical entities, encountered incidentally in approximately 0.1% of patients who undergo routine angiography. The most common cause of coronary artery aneurysms is atherosclerosis. Angiography is the gold standard for diagnosis and treatment. Depending on the severity of the coexisting coronary stenosis, patients with left main coronary artery aneurysms can be effectively managed either surgically or pharmacologically. We herein report a case of left main coronary artery aneurysm in a 72-year-old man with a prior history of hypertension presenting to our hospital because of unstable angina. The electrocardiogram showed ST-segment depression and T-wave inversion in the precordial leads. All the data of blood chemistry were normal. Echocardiography showed akinetic anterior wall, septum, and apex, mild mitral regurgitation and ejection fraction of 45%. Coronary angiography revealed a saccular aneurysm of the left main coronary artery with significant stenosis in the left anterior descending, left circumflex, and right coronary artery. The patient immediately underwent coronary artery bypass grafting and ligation of the aneurysm. At six months’ follow-up, he remained asymptomatic.

    Prognosis of colon cancer (CC) has steadily improved during the past three decades. This trend, however, may vary according to proximal (right) or distal (left) tumor location. We studied if improvement in survival was greater for left than for right CC. We included all CC recorded at the Geneva population-based registry between 1980 and 2006. We compared patients, tumor and treatment characteristics between left and right CC by logistic regression and compared CC specific survival by Cox models taking into account putative confounders. We also compared changes in survival between CC location in early and late years of observation. Among the 3396 CC patients, 1334 (39%) had right-sided and 2062 (61%) left-sided tumors. In the early 1980s, 5-year specific survival was identical for right and left CCs (49% vs. 48%). During the study period, a dramatic improvement in survival was observed for patients with left-sided cancers (Hazard ratio [HR]: 0.42, 95% confidence interval [CI]: 0.29-0.62, p colon cancer patients, those with right-sided lesions have by far the worse prognosis.

    Matsuyama, S.; Watabe, T.; Kuribayashi, S.

    1983-01-01

    Conventional posteroanterior chest radiographs of 42 patients with mitral valve disease who had had surgery were analyzed, and particular attention was directed to the presence or absence of the convexity of the left lower midcardiac border (left artrial segment). The flatness or concavity of this segment, despite other evidence of left atrial enlargement, was observed in six (60%) of 10 patients who had left atrial thrombosis, and in three (9%) of 32 patients who did not have thrombosis (false positive diagnosis). Four of the 10 patients who had left atrial thrombosis did not show this finding on the radiographs (false negative diagnosis). One of these four had a thrombus only against the posterior wall of the body of the left atrium. Therefore, the accuracy in the diagnosis of thrombosis of the left atrial appendage was 66.7% (six of nine) for patients who had thrombosis of the appendage. Standard chest radiographs are important in the evaluation of the patient with thrombosis of the left atrial appendage

    This paper analyzes the border effect, which indicates how biased interregional trade is, compared with international trade, by means of the Gravity Model. The border effect reveals how open to the foreign countries the nation is. This research suggests that the border effect in Japan is much lower than that of the US and Canada, and has declined year by year. Furthermore, in 1990, the border effect faded out. These trends may be reflected by international incidents such as the surge of the f...

In a pilot open-label study, we investigated the effect of a dietary supplement, BioCell Collagen® (BCC, which contains a naturally occurring matrix of hydrolyzed collagen type II and low-molecular-weight hyaluronic acid and chondroitin sulfate, in 26 healthy females who displayed visible signs of natural and photoaging in the face. Daily supplementation with 1 g of BCC for 12 weeks led to a significant reduction of skin dryness/scaling (76%, P = 0.002 and global lines/wrinkles (13.2%, P = 0.028 as measured by visual/tactile score. Additionally, a significant increase in the content of hemoglobin (17.7%, P = 0.018 and collagen (6.3%, P = 0.002 in the skin dermis was observed after 6 weeks of supplementation. At the end of the study, the increase in hemoglobin remained significant (15%, P = 0.008, while the increase in collagen content was maintained, but the difference from baseline was not significant (3.5%, P = 0.134. This study provides preliminary data suggesting that dietary supplementation with BCC elicits several physiological events which can be harnessed to counteract natural photoaging processes to reduce visible aging signs in the human face. A controlled study is necessary to verify these observations.Keywords: BioCell Collagen, chicken sternal cartilage extract, hydrolyzed collagen type II, low-molecular-weight hyaluronic acid, skin aging

  15. Effect of the US-Mexico border region in cardiovascular mortality: ecological time trend analysis of Mexican border and non-border municipalities from 1998 to 2012.

    Anaya, Gabriel; Al-Delaimy, Wael K

    2017-05-06

    An array of risk factors has been associated with cardiovascular diseases, and developing nations are becoming disproportionately affected by such diseases. Cardiovascular diseases have been reported to be highly prevalent in the Mexican population, but local mortality data is poor. The Mexican side of the US-Mexico border has a culture that is closely related to a developed nation and therefore may share the same risk factors of cardiovascular diseases. We wanted to explore if there was higher cardiovascular mortality in the border region of Mexico compared to the rest of the nation. We conducted a population based cross-sectional time series analysis to estimate the effects of education, insurance and municipal size in Mexican border (n = 38) and non-border municipalities (n = 2360) and its association with cardiovascular age-adjusted mortality rates between the years 1998-2012. We used a mixed effect linear model with random effect estimation and repeated measurements to compare the main outcome variable (mortality rate), the covariates (education, insurance and population size) and the geographic delimiter (border/non-border). Mortality due to cardiovascular disease was consistently higher in the municipalities along the US-Mexico border, showing a difference of 78 · 5 (95% CI 58 · 7-98 · 3, p Mexico border region is disproportionately affected by cardiovascular disease mortality as compared to the non-border region of Mexico. This was not explained by education, population density, or insurance coverage. Proximity to the US culture and related diet and habits can be explanations of the increasing mortality trend.

    We reported 7 patients with left thalamic hemorrhage in the chronic stage (from 1.5 months to 4.5 months), and described language disorders examined by Western Aphasia Battery (WAB) and measured cerebral blood flow by single photon emission CT. Examination of language by WAB revealed 4 aphasics out of 7 cases, and 3 patients had no language deficit. The patient with Wernicke's aphasia showed low density area only in the left posterior thalamus in X-ray CT, and revealed severe low blood flow area extending to left temporal lobe in emission CT. In the case with transcortical sensory aphasia, although X-ray CT showed no obvious low density area, emission CT revealed moderate low flow area in watershed area that involved the territory between posterior cerebral and middle cerebral arteries in the left temporooccipital region in addition to low blood flow at the left thalamus. In one of the two patients classified as anomic aphasia, whose score of repetition (8.4) was higher than that of comprehension (7.4), emission CT showed slight low flow area at the temporo-occipital region similarly as the case with transcortical sensory aphasia. In another case with anomic aphasia, scored 9 on both fluensy and comprehension subtests and 10 on repetition, there was wide low density area all over the left thalamus and midline shift to the right in X-ray CT, and emission CT showed severe low blood flow in the same region spreading widely toward the cerebral surface. On the other hand, in all of the 3 patients without aphasia, emission CT showed low flow region restricted to the left thalamus. (J.P.N.)

  17. Who’s Who at the Border? A rights-based approach to identifying human trafficking at international borders

    Directory of Open Access Journals (Sweden)

    Marika McAdam

    2013-09-01

    Full Text Available International borders are widely touted as bastions in the fight against trafficking in persons. This article acknowledges the important role border officials play in preventing human trafficking, but calls for expectations to be tempered by deference to the conceptual complexity of cross-border trafficking and the migration processes involved. The fact that many trafficked victims begin their journeys as irregular or smuggled migrants highlights the challenge posed to border officials in identifying trafficked persons among the people they encounter. Indicators of trafficking generally relate to the exploitation phase, leaving border officials with little guidance as to how persons vulnerable to trafficking can be accurately identified before any exploitation has occurred. Ultimately, this paper advocates a pragmatic rights-based approach in designating anti-trafficking functions to border officials. A rights-based approach to border control acknowledges the core work of border officials as being to uphold border integrity, while ensuring that their performance of this role does not jeopardise the rights of those they intercept nor result in missed opportunities for specialists to identify trafficked persons and other vulnerable people among them.

  18. Snowstorm Along the China-Mongolia-Russia Borders

    Science.gov (United States)

    2004-01-01

    Heavy snowfall on March 12, 2004, across north China's Inner Mongolia Autonomous Region, Mongolia and Russia, caused train and highway traffic to stop for several days along the Russia-China border. This pair of images from the Multi-angle Imaging SpectroRadiometer (MISR) highlights the snow and surface properties across the region on March 13. The left-hand image is a multi-spectral false-color view made from the near-infrared, red, and green bands of MISR's vertical-viewing (nadir) camera. The right-hand image is a multi-angle false-color view made from the red band data of the 46-degree aftward camera, the nadir camera, and the 46-degree forward camera. About midway between the frozen expanse of China's Hulun Nur Lake (along the right-hand edge of the images) and Russia's Torey Lakes (above image center) is a dark linear feature that corresponds with the China-Mongolia border. In the upper portion of the images, many small plumes of black smoke rise from coal and wood fires and blow toward the southeast over the frozen lakes and snow-covered grasslands. Along the upper left-hand portion of the images, in Russia's Yablonovyy mountain range and the Onon River Valley, the terrain becomes more hilly and forested. In the nadir image, vegetation appears in shades of red, owing to its high near-infrared reflectivity. In the multi-angle composite, open-canopy forested areas are indicated by green hues. Since this is a multi-angle composite, the green color arises not from the color of the leaves but from the architecture of the surface cover. The green areas appear brighter at the nadir angle than at the oblique angles because more of the snow-covered surface in the gaps between the trees is visible. Color variations in the multi-angle composite also indicate angular reflectance properties for areas covered by snow and ice. The light blue color of the frozen lakes is due to the increased forward scattering of smooth ice, and light orange colors indicate rougher ice or

    Kime, Philip

    2016-11-01

    Nina Coltart's freedom in addressing delicate areas such as spirituality and Buddhism within a psychoanalytic framework has opened borders between different psychoanalytic communities. This paper sets out to identify a deep-rooted philosophical tension that runs through several aspects of Coltart's work starting from her 'Slouching towards Bethlehem … or, thinking the unthinkable in psychoanalysis'. In exploring this central topic in depth psychology, of the distinction between thinkable and unthinkable contents, the author argues that it is not a fundamental distinction in Coltart's work but is rather a particular example of a more fundamental structural dichotomy which pervades her approach and which manifests in several different guises. It is the breadth and sincerity of Coltart's writings which make this a useful exercise, not only for understanding the structure of her work but also in illuminating some structural tensions which permeate depth-psychological pursuits in general. © 2016, The Society of Analytical Psychology.

    2015-08-01

    Full Text Available The globalization of the world economy has opened up new possibilities for cross-border labor organizing. In fact, several U.S. unions are working together with unions from Mexico, Honduras, Guatemala, the Dominican Republic, Japan, South Korea, and many European nations. For example, over the last several years, UNITE (Union of Needletrades, Industrial, and Textile Employees, the AFL-CIO, and the international garment workers trade secretariat have worked directly with maquiladora workers in Honduras and the Dominican Republic. These efforts led to the formation of several labor unions and the first contracts ever negotiated in the maquiladoras in the Dominican Republic. In addition, labor rights and solidarity organizations, like the Campaign for Labor Rights, Witness for Peace, and the US/Guatemala Labor Education Project (US/GLEP, along with many other groups, have also played key roles in the formation of maquiladora unions in Nicaragua and Guatemala.

  1. Nuclear Plants in the Vicinity of Borders

    International Nuclear Information System (INIS)

    Wertz, Elmar.

    1979-01-01

    The siting of nuclear power plants in border areas is decided according to 'national criteria' which are governed by the cost/benefit principle, i.e. a comparison between investment and profit; human values are taken into consideration by transforming them into financial values according to the 'quantification' procedure. However ecology cannot be quantified as it is linked to the great complexity of the natural system. To harmonize technical criteria and ecological requirements, the jurist suggests a legal system of indemnity which takes into account both damage which has already occurred and the degree of probability of its occurrence. Thus a new criterion would be introduced in the decision-making process on plant siting: compensation costs for the national population and for the neighbouring countries would then be a factor in cost/benefit calculations.

  2. POSTMODERN EDUCATION: CRITICAL AND BORDER PEDAGOGIES

    Directory of Open Access Journals (Sweden)

    Mustafa Kurt

    2006-12-01

    Full Text Available This article discusses the influence of postmodernism on education and investigates the main effects ofpostmodern philosophy on social sciences. It is clearly stated in the article that the effects of postmodernism cannotonly be limited to art and logically it should have an effect on education as well. This effect, described as thepostmodern educational approach, emphasizes that the rudiments of popular culture should also be incorporated toeducation and therefore to curricula. Postmodern educational approach also accentuates the significance of allowing‘others’ who have never possessed the opportunity to articulate their standpoints and desires to have a say in their owneducation. The concrete reflections of postmodern educational approach can be perceived in Critical and BorderPedagogies theorized by Henry A. Giroux. Critical pedagogy aspires to educate individuals who do not acceptoccurrences as they are and are critical of the knowledge they construct all through their education. Only by this waythese individuals will be able to discover their own voices, improve their civilian consciousness by taking risks, andacquire the ability of staying alive and functioning within social relations, traditions and experiences. Border pedagogyis as well a product of postmodern philosophy. It defends counter-text as opposed to the official ones offered, presentedand imposed to learners. Counter-consciousness represents the critical analysis of how the present reads the past andhow the past informs the present. This practice of course results in the re-evaluation of memories and traditions.Memories are the stories which were forgotten or ignored with the support of preserved traditions. It is thereforeconcluded in the article that postmodern educational approach is the critical examination towards dismissing the mainnarratives and discourses which manipulate and configure the curriculum of schools. It is the struggle exercisedtowards the recognition

    2014-06-01

    Full Text Available This article traces the lives of a group of Vietnamese women driven by poverty and loss of marriageability to cross the border into China to marry men from the fishing village of Wanwei. Wanwei’s location, only 25 kilometers from the border with Vietnam, enables these women to make fairly regular trips back to their native villages to visit their birth families. Yet, despite the fact that they now live in a designated Jing (ethnic Vietnamese village, where a significant proportion of the population shares their ethnicity, their illegal residential status and recent arrival excludes them from the community of villagers who claim descent from Vietnamese immigrants in the sixteenth century. Despite the hardships these women face as a result of continuing poverty, lack of emotional intimacy in their marriages, and marginal social status, few see themselves as victims of human trafficking. Instead, most take pride in their agency and achievements.

    2015-10-01

    We provide the first evidence on the causal effect of border enforcement on the full spatial distribution of Mexican immigrants to the United States. We address the endogeneity of border enforcement with an instrumental variables strategy based on administrative delays in budgetary allocations for border security. We find that 1,000 additional Border Patrol officers assigned to prevent unauthorized migrants from entering a U.S. state decreases that state's share of Mexican immigrants by 21.9 %. Our estimates imply that if border enforcement had not changed from 1994 to 2011, the shares of Mexican immigrants locating in California and Texas would each be 8 percentage points greater, with all other states' shares lower or unchanged.

    2017-06-01

    Full Text Available This article is concerned with cross-border tourism. It enhances the importance of cross-border cooperation in tourism. Cross-border cooperation is a form of international cooperation, along with interregional, transitional and trans-frontier cooperation. Cross-border regions often share the same historical and cultural traditions and attractive natural landscapes, such is the case of the Republic of Moldova and Romania. In both cases, cross-border regions can benefit from cooperation – cooperation can help create greater diversity and differentiation of the range of tourism and environmental products; create economies of scale and make promotion more effective, and can help better address specific problems or issues for tourism development.

  1. Parhelic-like circle from light scattering in Plateau borders

    2015-03-06

    We are reporting a new simple optical element to generate halos. We have observed interesting patterns of light scattering in Plateau borders in foams. In analogy to the atmospheric phenomena known as parhelic circle, sun dogs, and sun pillars, we have named the features of the patterns observed as parlaseric circle, laser dogs, and laser pillars. The triangular symmetry of the Plateau borders is analogous to the hexagonal symmetry of ice crystals which produce these atmospheric phenomena. Working with one Plateau border at a time, we have observed wave optics phenomena that are not perceived in the atmospheric phenomena, such as diffraction and interference. - Highlights: • We obtained halo formation from light scattering in a Plateau border using an experiment. • We explained halo formation using geometrical theory of diffraction. • An optical element based on a Plateau border is proposed. • We compared some aspects of the parhelic circle with the parlaseric circle.

    2015-03-01

    Full Text Available The symmetry and/or asymmetry in terms of cross-border openness of service providers is examined in this article, for the cases of two border twin towns: Cieszyn/Český Těšín at the Polish-Czech border, and Gubin/Guben at the Polish-German border. To assess the level of openness of firms towards clients from the other side of the border, four trans-border categories were examined: neighbour’s language visible at store location; business offers in the language of the neighbour; the possibilities of payment in the neighbour’s currency; and the staff’s knowledge of the language. This enabled a comparison of both parts of the particular twin towns in relation to the character of cross-border openness, as well as an assessment of their symmetry/asymmetry. Comparisons of Gubin/Guben and Cieszyn/Český Těšín with respect to the analysed features were also carried out. The analysis shows significant variation in the level of cross-border openness towards clients from neighbouring countries. Whereas in the Polish-Czech town a relative symmetry was observed, in the Polish-German case, significant asymmetry was noted.

    To identify and evaluate the lateral border zone by comparing the size and distribution of the abnormal signal area demonstrated by MR imaging with the infarct area revealed by pathological examination in a reperfused myocardial infarction cat model. In eight cats, the left anterior descending coronary artery was occluded for 90 minutes, and this was followed by 90 minutes of reperfusion. ECG-triggered breath-hold turbo spin-echo T2-weighted MR images were initially obtained along the short axis of the heart before the administration of contrast media. After the injection of Gadomer-17 and Gadophrin-2, contrastenhanced T1-weighted MR images were obtained for three hours. The size of the abnormal signal area seen on each image was compared with that of the infarct area after TTC staining. To assess ultrastructural changes in the myocardium at the infarct area, lateral border zone and normal myocardium, electron microscopic examination was performed. The high signal area seen on T2-weighted images and the enhanced area seen on Gadomer-17-enhanced T1WI were larger than the enhanced area on Gadophrin-2-enhanced T1WI and the infarct area revealed by TTC staining; the difference was expressed as a percentage of the size of the total left ventricle mass (T2= 39.2 %; Gadomer-17 =37.25 % vs Gadophrin-2 = 29.6 %; TTC staining = 28.2 %; p < 0.05). The ultrastructural changes seen at the lateral border zone were compatible with reversible myocardial damage. In a reperfused myocardial infarction cat model, the presence and size of the lateral border zone can be determined by means of Gadomer-17- and Gadophrin-2-enhanced MR imaging

    1987-02-01

    To study left ventricular diastolic performance in different forms of left ventricular hypertrophy, ECG gated cardiac blood pool scan was performed in 11 patients with hypertrophic nonobstructive cardiomyopathy (HCM) and in 19 patients with hypertension (HT), and left ventricular volume curve (LVVC) was analyzed and compared with those of 13 normal subjects (N). Ejection fraction (EF) and early filling volume ratio (the ratio of volume increment of 100 msec later than the zero point in the first derivative of LVVC to the end diastolic volume) (%EFV) were computed from LVVC. Peak ejection rate (PER) and peak filling rate (PFR) were obtained from the first derivative of LVVC. Peak ejection acceleration (PEA) and peak filling acceleration (PFA) were calculated from the second derivative of LVVC. EF, PER and PEA did not show any difference between these 3 groups. PFR was lower in HT (2.6 +- 0.5) compared with those in HCM (3.0 +- 0.5) (p < 0.05) and in N (3.4 +- 0.5) (p < 0.001), but the %EFV in HCM (4.9 +- 1.8) was lower than those in HT (6.9 +- 1.9) (p < 0.01) and in N (11.4 +- 1.4) (p < 0.001). Moreover, PFA in HCM (27.9 +- 7.2) was increased than those in HT (20.2 +- 5.4) (p < 0.01) with no differences between HCM and N (29.4 +- 8.1). Significant correlation was observed between PFR and PFA (Y = 0.06X + 1.4. r = 0.856. p < 0.001). These result indicate that, in HCM, reduced increase in early left ventricular volume is compensated by a greater filling acceleration. In contrast, there is no compensation by filling acceleration in HT.

  15. An open mind to closed borders

    2017-04-01

    One aspect of "Science in tomorrow's classroom" is teaching geography students the basic skills and knowledge to play an active role in society as citizens. Topics that frame the development of good citizenship are wide-ranged and include climate change, migration and integration as well as democracy and identity. Often these kinds of topics do not allow for right or wrong answers or classroom lectures; it is more important to encourage students to find and discuss arguments with which to underpin their opinion. In this way, civic education is very suitable for active learning. Active learning is described as a method of learning in which students are actively involved in the learning process through (group) discussion, experiments or games. By doing so, students are stimulated to engage in higher-order thinking tasks such as analysis, synthesis, and evaluation, which are inherent to becoming responsible, reflective and critical citizens as well as (future) scientists. It has also been shown that the use of active learning methods significantly increased the number of meaningful geographical relationships that students give in tests (Karkdijk, 2012). I, therefore, propose to use active learning to approach civic education in the classroom. Specifically, I used a "mystery" to engage students in active learning on the highly polarizing subject of migration. A mystery (Leat, 1990) is a didactic method that uses short bits of information to solve an intriguing question. A current polarizing subject in society and in the classroom is the migration from Northern Africa and the Middle East to Europe and the increasing number of terrorist attacks by individuals who have radicalised before, during or after their journey over the Mediterranean. In class, students were asked to solve this migration mystery: "Could the terrorist attack in Berlin have been stopped by closing the borders of the Mediterranean countries to migrants?" In order to solve this mystery and to find an

    The emissions of zinc along roads originating from tyre wear, corrosion of safety fence and other traffic-related sources have been quantified and validated by measured long-term loads in road run-off and airborne solids (drift) for 29 published case studies. The distribution pattern over the road border at various distances from the edge of the paved surface is assessed on the basis of 38 published case studies with measured concentrations in soil. For the impact assessment, the road border is differentiated into a zone that is part of the 'technosphere' and the 'target zone' beyond that technosphere that can be considered as part of the receiving environment. The 'technosphere' of the road includes the central reservation, the hard and the soft shoulder or, if one or both shoulders are not present, the so-called obstacle 'free zone' that is defined by road engineers. Pollution within the technosphere may require appropriate management of solid disposal and isolation from groundwater to prevent further distribution of pollutants to the environment. In the target zone along regional roads, the zinc load is about 4 mg/m{sup 2} year and this is of the same order of magnitude as that of atmospheric deposition in areas beyond the influence of roads (background). In the target zone along highways, the zinc load is increased in comparison to the background deposition. The average load of about 38 mg/m{sup 2} year is similar to that in fertilised agricultural land. Because most of the emitted zinc stays in the technosphere, the total amount entering this target zone along highways is limited. From the 140 tons of zinc per year that is released from tyre wear in The Netherlands, 64 tons is emitted in the urban area, 6.5 tons reaches to the target zones of all roads and only 1.1 tons of zinc will enter the target zone along highways. This amount will be further decreased by the application of porous asphalt in the near future. The

    The lateral neural plate border (NPB), the neural part of the vertebrate neural border, is composed of central nervous system (CNS) progenitors and peripheral nervous system (PNS) progenitors. In invertebrates, PNS progenitors are also juxtaposed to the lateral boundary of the CNS. Whether there are conserved molecular mechanisms determining vertebrate and invertebrate lateral neural borders remains unclear. Using single-cell-resolution gene-expression profiling and genetic analysis, we present evidence that orthologs of the NPB specification module specify the invertebrate lateral neural border, which is composed of CNS and PNS progenitors. First, like in vertebrates, the conserved neuroectoderm lateral border specifier Msx/vab-15 specifies lateral neuroblasts in Caenorhabditis elegans Second, orthologs of the vertebrate NPB specification module ( Msx/vab-15 , Pax3/7/pax-3 , and Zic/ref-2 ) are significantly enriched in worm lateral neuroblasts. In addition, like in other bilaterians, the expression domain of Msx/vab-15 is more lateral than those of Pax3/7/pax-3 and Zic/ref- 2 in C. elegans Third, we show that Msx/vab-15 regulates the development of mechanosensory neurons derived from lateral neural progenitors in multiple invertebrate species, including C. elegans , Drosophila melanogaster , and Ciona intestinalis We also identify a novel lateral neural border specifier, ZNF703/tlp-1 , which functions synergistically with Msx/vab- 15 in both C. elegans and Xenopus laevis These data suggest a common origin of the molecular mechanism specifying lateral neural borders across bilaterians.

    Progressive lameness and leg pain were the predominant clinical signs in a 17-week-old male border collie presented for examination. On clinical investigation, extrahepatic cholestasis in association with rickets due to inadequate vitamin D resorption was diagnosed. The dog was treated parenterally with vitamin D and a cholecystoduodenostomy was performed. At 25 days postsurgery the lameness had resolved and bone structure was radiographically normal. However, at six weeks postsurgery, the dog's condition deteriorated rapidly and euthanasia was finally performed at eight weeks postsurgery. At postmortem examination, Toxocara canis nematodes were found to have invaded the biliary system via the anastomosis between the gallbladder and duodenum, causing biliary and hepatic toxocariasis. The cause of the primary extrahepatic cholestasis was atresia of the common bile duct at the hepatic end. The liver tissue showed microscopic lesions of chronic extrahepatic cholestasis as well as acute inflammation associated with the nematode invasion. There was no postmortem evidence of bone lesions. Extrahepatic biliary atresia is extremely rare in animals and has not been described before in dogs. In contrast, it represents the most common cause of congenital cholestasis in children, occurring in approximately one per 10,000 to 15,000 live births.

  20. Border Collision Route to Quasiperiodicity: Numerical Investigation and Experimental Confirmation

    2006-01-01

    Numerical studies of higher-dimensional piecewise-smooth systems have recently shown how a torus can arise from a periodic cycle through a special type of border-collision bifurcation.

    This paper attempts to show causes of border conflict between Thailand and Cambodia, and to look for the means of solving the conflict. Preah Vihear Temple is an old Khmer temple ruins situated on the border of Thailand and Cambodia. UNESCO decided to list it as a World Heritage Site on July 7, 2008. However, the two countries have been in a state of border conflict since that time. The conflict leaves dozens of casualties. This paper shows that there are two causes of conflict. The first one...

    2017-05-01

    Full Text Available Border tourism is the temporary displacement of people to the dividing line between two countries contiguous areas. This activity promotes the economic development of these geographical regions. The aim of this research is to analyze visitors from the Dominican Republic and Haiti border. We propose the results of an empirical study with structural equations that show correlations between the attitude factor towards the border tourism, the value factors perceived by the tourist, satisfaction and loyalty of the visitor in the destination place.

    Social and cultural conditions (including U.S. border and inland influence, role models within the family, and educational background) which affect locus of control and achievement motivation among Mexican entrepreneurs were explored among 64 selected entrepreneurs in two Mexican towns, one on the Mexico-U.S. border, the other located inland. Analyses showed that the border subsample scored higher on External locus of control; however, in both subsamples the father was an important element in the locus of control variable and the entrepreneur status. No statistically significant mean difference was noted for achievement motivation. Practical applications and limitations are discussed.

  4. CHANGING BORDERS, RETHINKING SOVEREIGNTY: TOWARDS A RIGHT TO MIGRATE

    Directory of Open Access Journals (Sweden)

    Maribel Casas-Cortes

    Full Text Available Abstract The intervention of European Union border authorities in countries of Africa, Asia and Eastern Europe has shown how the European state “border” has been displaced from its national moorings and externalized across the territories of neighboring states. Our research examines the outsourcing of the southern European Union border, focusing on the case of Spain and its relationship with Morocco and countries of Western Africa. In this paper we describe the development and implementation of this strategy of migration management, signaling implications of border externalization from the point of geopolitics and legality, including a suggestive call to reclaim the legal tradition of the Right to Migrate.

    Cherpitel, Cheryl J.; Ye, Yu; Bond, Jason; Zemore, Sarah E.; Borges, Guilherme; Greenfield, Thomas K.

    2015-01-01

    Background Little epidemiological evidence exists on alcohol use and related problems along the U.S.-Mexico border, although the borderlands have been the focus of recent media attention related to the escalating drug/violence “epidemic”. In the present study the relationship of proximity of living at the border and alcohol use disorders (AUDs) is analyzed from the U.S.-Mexico Study on Alcohol and Related Conditions (UMSARC). Methods Household surveys were conducted on 2,336 Mexican Americans in Texas (771 in a non-border city and 1,565 from three border cities located in the three poorest counties in the U.S.) and 2,460 Mexicans from the states of Nuevo Leon and Tamaulipas in Mexico (811 in a non-border city and 1,649 from three cities which are sister cities to the Texas border sites). Results Among current drinkers, prevalence of AUD was marginally greater (pMexico (pMexico. Conclusion The data suggest that border proximity may affect AUD in both the U.S. and Mexico, but in the opposite direction, and may be related to the relative perceived or actual stress of living in the respective communities.

  7. Celebrity chefs put their left cheek forward: Cover image orientation in celebrity cookbooks.

    Lindell, Annukka K

    2017-09-01

    Portrait pose orientations influence perception: the left cheek is more emotionally expressive; females' right cheeks appear more attractive. Posing biases are established in paintings, photographs, and advertisements, however, book covers have not previously been examined. This paper assesses cover image orientation in a book genre that frequently features a cover portrait: the celebrity cookbook. If marketers intuitively choose to enhance chefs' emotional expressivity, left cheek poses should predominate; if attractiveness is more important, right cheek poses will be more frequent for females, with a left or no cheek bias for males. Celebrity cookbook covers (N = 493) were sourced online; identity, portrait orientation, photo type, and sex were coded. For celebrity cookbooks, left cheek covers (39.6%) were more frequent than right cheek (31.6%) or midline covers (28.8%); sex did not predict pose orientation. An interaction between photo type and sex bordered on significance: photo type did not influence females' pose orientation; for males, the left cheek bias present for head and torso images was absent for full body and head only photos. Overall, the left cheek bias for celebrity cookbook covers implies that marketers intuitively select images that make the chefs appear happier and/or more emotionally expressive, enhancing engagement with the audience.

    The aim of this study was to evaluate the quality of the data provided from sheepdog trials in Norway, estimate heritabilities, repeatabilities and genetic correlations for the traits included in the trial and make recommendations on how sheepdog trials best can be utilized in the breeding of Border Collies in Norway. The analyses were based on test results from sheepdog trials carried out in Norway from 1993 to 2012. A total of 45 732 records from 3841 Border Collies were available, but after quality assurance only a third was left. The results demonstrated little information in the data. Heritabilities varied between 0.010 and 0.056 with standard errors ranging from 0.010 to 0.023, while repeatabilities ranged from 0.041 to 0.286. There is a need to assure the quality of data to improve the information in the test results. We recommend adding new traits based on the Herding Trait Characterization scheme evaluated in Sweden, and on traits from the predatory motor pattern, regarded as common for all dogs. These new traits may be scored across the elements that make up the current trial system, which should be kept in place to stimulate participation in the genetic evaluation scheme. © 2016 Blackwell Verlag GmbH.

  12. Definig the US-Mexico border as hyperreality

    Directory of Open Access Journals (Sweden)

    Carlos A. Duarte-Herrera

    2002-07-01

    Full Text Available The US-Mexico border has been defined as a periphery, as a transborder social system, and more currently, as a station in transnational circuits. The two first definitions presuppose the strongly criticized concepts of region and cultural area. The third definition shares, along with the other two definitions, the positivist epistemological supposition that the border is a specific entity that can be known and experienced as such by any observer, no matter their social site. This paper is to support the definition of the border as a hyperreality constituted by speeches, practices, and experiences of the different social actors. From this posture, the image of the border as a formal geopolitical division is interpreted as a sustained image and reproduced by government agencies. Likewise, this writing is to support the documentation and promotion of alternative images constructed and reproduced by social actors from different power sites.

  13. Shaping the Victim: Borders, security, and human trafficking in Albania

    Directory of Open Access Journals (Sweden)

    James Campbell

    2013-09-01

    Full Text Available Borders are productive sites where knowledge is gathered and migrant populations are formed. The knowledge gathered from victims of trafficking reinforces a victim narrative that represents a perceived threat to society by highlighting violence, criminality, coercion, and naivety. Using Albania as a case in point, the article looks at trafficked people and the narratives of victimhood that surround them. In the case of trafficked people, the border projected out towards other states produces a discursively defined victim of trafficking. When projected back within the national territory, the border essentially produces a criminalised sex worker. To argue this point, the article discusses the role victims of trafficking play in the EU and looks at how international norms espoused by the OSCE and IOM have prepped the Albanian border for EU ascension and created the means for governable populations within Albania.

  14. Smuggling and cross border shopping of tobacco in Europe.

    Science.gov (United States)

    Joossens, L; Raw, M

    1995-05-27

    Governments have recently become concerned about cross border shopping and smuggling because it can decrease tax revenue. The tobacco industry predicted that, with the removal of border controls in the European Union, price differences between neighbouring countries would lead to a diversion of tobacco trade, legally and illegally, to countries with cheaper cigarettes. According to them this diversion would be through increased cross border shopping for personal consumption or through increased smuggling of cheap cigarettes from countries with low tax to countries with high tax, where cigarettes are more expensive. These arguments have been used to urge governments not to increase tax on tobacco products. The evidence suggests, however, that cross border shopping is not yet a problem in Europe and that smuggling is not of cheap cigarettes to expensive countries. Instead, more expensive "international" brands are smuggled into northern Europe and sold illegally on the streets of the cheaper countries of southern Europe.

    Infective endocarditis (IE) in dogs with cardiac shunts has not been reported previously. However, we encountered a dog with concurrent patent ductus arteriosus (PDA) and IE. The dog was a 1-year-old, 13.9-kg female Border collie and presented with anorexia, weight loss, pyrexia (40.4 °C) and lameness. A continuous murmur with maximal intensity over the left heart base (Levine 5/6) was detected on auscultation. Echocardiography revealed a PDA and severe aortic stenosis (AS) caused by aortic-valve vegetative lesions. Corynebacterium spp. and Bacillus subtilis were isolated from blood cultures. The dog responded to aggressive antibiotic therapy, and the PDA was subsequently surgically corrected. After a series of treatments, the dog showed long-term improvement in clinical status.

  2. Cross-border Ties and Arab American Mental Health

    2016-01-01

    Due to increasing discrimination and marginalization, Arab Americans are at a greater risk for mental health disorders. Social networks that include ties to the country of origin could help promote mental well-being in the face of discrimination. The role of countries of origin in immigrant mental health receives little attention compared to adjustment in destination contexts. This study addresses this gap by analyzing the relationship between nativity, cross-border ties, and psychological distress and happiness for Arab Americans living in the greater Detroit Metropolitan Area (N=896). I expect that first generation Arab Americans will have more psychological distress compared to one and half, second, and third generations, and Arab Americans with more cross-border ties will have less psychological distress and more happiness. Data come from the 2003 Detroit Arab American Study, which includes measures of nativity, cross-border ties – attitudes, social ties, media consumption, and community organizations, and the Kessler-10 scale of psychological distress and self-reported happiness. Ordered logistic regression analyses suggest that psychological distress and happiness do not vary much by nativity alone. However, cross-border ties have both adverse and protective effects on psychological distress and happiness. For all generations of Arab Americans, cross-border attitudes and social ties are associated with greater odds of psychological distress and for first generation Arab Americans, media consumption is associated with greater odds of unhappiness. In contrast, for all generations, involvement in cross-border community organizations is associated with less psychological distress and for the third generation, positive cross-border attitudes are associated with higher odds of happiness. These findings show the complex relationship between cross-border ties and psychological distress and happiness for different generations of Arab Americans. PMID:26999416

    Two multicenter studies were conducted to evaluate the safety and efficacy of SonoVue as a contrast agent for enhanced left ventricular endocardial border delineation (LVEBD), and to compare the efficacy of SonoVue and Albunex in adult patients with a suboptimal, nonenhanced echocardiogram. The use of contrast to enhance echocardiographic assessment of LVEBD is well-established. SonoVue is a new microbubble contrast agent that contains sulfur hexafluoride. Patients were randomized to receive four injections of SonoVue (0.5, 1, 2, and 4 ml), or two injections of Albunex and two injections of hand-agitated saline (0.08 and 0.22 ml/kg). Echocardiographic images were evaluated at the study centers and by four blinded, offsite reviewers for degree of left ventricle opacification (LVO), duration of contrast enhancement, and LVEBD. LVO scores were significantly higher for all doses of SonoVue. Patients with complete LVO ranged from 34%-87% for SonoVue and from 0%-16% for Albunex. The mean duration of useful contrast effect ranged from 0.8-4.1 minutes for SonoVue and SonoVue and 0.1-4.3 for Albunex. SonoVue (cumulative 7.5 ml dose) was well-tolerated, with a safety profile similar to that observed in the control group. SonoVue is superior to Albunex for improving visualization of endocardial borders in patients with suboptimal noncontrast echocardiograms. Optimal increases in LVEBD, LVO, and duration of useful contrast effect were observed at the 2.0 ml dose of SonoVue.

  14. Cross-border Specialization of Interregional Interaction: Applying New Assessment Methods

    Directory of Open Access Journals (Sweden)

    Mezhevich Nikolai

    2013-03-01

    Full Text Available Cross-border cooperation as a type of interregional interaction is becoming a significant factor in the development of border regions. It can be viewed as a result of intensification of cross-border contacts and greater economic openness of cross-border regions. Thus, the roots of current development are quite easy to pinpoint. However, assessment of the impact of cross-border cooperation on the development of border regions appears to be a research challenge. In this paper, we offer an approach to the assessment of the role of cross-border cooperation in the system of interregional interaction between border regions. We present a system of indices to describe cross-border specialization of interregional interaction in certain fields, namely investment, international trade, tourism, and migration. Cross-border specialization determines the role of cross-border cooperation in regional external relations. The empiric data we have gathered is used to develop and implement a pilot assessment of cross-border specialization of interregional relations which are characteristic of the border regions of the Northwestern Federal District of the Russian Federation. The article offers cross-border specialization indices for each border region of the Northwestern Federal District. With their help, we were able to identify the spheres of interaction with the highest degree of cross-border specialization, and in particular foreign investment and business activities with the participation of foreign capital.

  15. Effect of the US-Mexico border region in cardiovascular mortality: ecological time trend analysis of Mexican border and non-border municipalities from 1998 to 2012

    Full Text Available Abstract Background An array of risk factors has been associated with cardiovascular diseases, and developing nations are becoming disproportionately affected by such diseases. Cardiovascular diseases have been reported to be highly prevalent in the Mexican population, but local mortality data is poor. The Mexican side of the US-Mexico border has a culture that is closely related to a developed nation and therefore may share the same risk factors of cardiovascular diseases. We wanted to explore if there was higher cardiovascular mortality in the border region of Mexico compared to the rest of the nation. Methods We conducted a population based cross-sectional time series analysis to estimate the effects of education, insurance and municipal size in Mexican border (n = 38 and non-border municipalities (n = 2360 and its association with cardiovascular age-adjusted mortality rates between the years 1998–2012. We used a mixed effect linear model with random effect estimation and repeated measurements to compare the main outcome variable (mortality rate, the covariates (education, insurance and population size and the geographic delimiter (border/non-border. Results Mortality due to cardiovascular disease was consistently higher in the municipalities along the US-Mexico border, showing a difference of 78 · 5 (95% CI 58 · 7-98 · 3, p < 0 · 001 more cardiovascular deaths after adjusting for covariates.

    is through community nutrition programmes that encourage the full participation and co-operation of the entire community, maximise the utilisation of local resources, grasp the benefits of new technologies for productivity gains, involve multiple sectors and engage strong political commitment. The international community will be judged by its treatment of its most vulnerable members. The international community has repeatedly declared that it is dedicated to the eradication of poverty. Eliminating hunger and malnutrition is a vital first step. The political will to fight hunger and a firm commitment to invest in agriculture' and rural development are critical elements in any effort to achieve sustainable alleviation of hunger and poverty. This meeting and the WFS:FYL provide the additional impetus to meet the challenge of achieving food and nutritional security in a world without borders and free from hunger and malnutrition.

    Full Text Available Background. The evolution from quadrupedalism to bipedalism has adjusted the balance of the upper limb to extensive movement at the shoulder. The scapular angles provide the point of attachment and control to various muscles and have been associated with the different movements of the shoulder girdle and joint. This has made the morphometric and anthropometric study of scapula a subject of extensive investigation. Aim. In the present study, the angle at the medial border was measured in the South-Southern Nigerian population and an anatomical name was ascribed to the angle. Method. The study was conducted on 173 scapulae (75 right and 98 left obtained from various Anatomy Department of South-Sothern Nigerian Universities. The angle at medial border was obtained by pinning the edge of the superior and inferior angles, the lined traced out, and the angle measured using a protractor. SPSS version 20 was used to analyse the data. t-test was used to determine mean angular difference in the sides. Result. The mean ± SD of the medial angle was observed to be 136.88 ± 7.70° (R = 138.13 ± 7.06° : L = 135.92 ± 8.05°. Statistical analysis using the Z-test for mean difference showed the medial angle was found to be higher in the right side of the scapula (mean difference of 2.214 ± 1.152°, but the observed difference was not statistically significant (P > 0.05. The above findings have adjusted the scapula from three to four angles (lateral, superior, inferior, and medial formed from four borders (lateral, superior, inferior, and superomedial and inferomedial. The medial angle because of its anatomical location was named “spinovertebral” angle, owing to its position at the scapulae spine, and located in medial proximity to the vertebra column. Conclusion. The medial angle (now referred to as the spinovertebral angle of the right side of the scapula is wider than the left. The representation of the spinovertebral angle is very important, as

  20. Late Gadolinium Enhancement of the right ventricular myocardium: Is it really different from the left ?

    Directory of Open Access Journals (Sweden)

    Macgowan Christopher K

    2008-05-01

    Full Text Available Abstract It has been suggested that, in late gadolinium enhancement, the signal of right ventricular myocardium is nulled at a shorter inversion time than the left. While we initially made the same observation, we believe that the difference is not real, but results from artifacts. We present 7 cases as well as computer simulations to describe the nature of these artifacts and explain how they can create the impression of different inversion times for the right and left ventricle. At inversion times that are shorter than ideal for the myocardium a black rim can be seen at the border of the myocardium with blood on the inside and with fat on the outside. This is most likely a partial volume effect. The thin myocardium of the right ventricle is sandwiched between these black rims and, at a low spatial resolution, is no longer visible. In this case, the adjacent black rims may then be misinterpreted as myocardium. While black rims also occur on the left side, the myocardium is thicker and remains discernable as a separate layer. As a consequence, the optimal inversion time for the right ventricle only appears different from that for the left. In fact, in the presence of hypertrophy of the right ventricle or during systolic wall thickening we did not find a difference in inversion times between the left and right ventricle. We conclude that sufficient spatial resolution is important for adequate late gadolinium enhancement of the right ventricle.

    We investigate the phenomenology of a simplified model of flavoured Dark Matter (DM), with a dark fermionic flavour triplet coupling to the left-handed SU(2) L quark doublets via a scalar mediator. The DM-quark coupling matrix is assumed to constitute the only new source of flavour and CP violation, following the hypothesis of Dark Minimal Flavour Violation. We analyse the constraints from LHC searches, from meson mixing data in the K, D, and B d,s meson systems, from thermal DM freeze-out, and from direct detection experiments. Our combined analysis shows that while the experimental constraints are similar to the DMFV models with DM coupling to right-handed quarks, the multitude of couplings between DM and the SM quark sector resulting from the SU(2) L structure implies a richer phenomenology and significantly alters the resulting impact on the viable parameter space.

    Full Text Available Border issues have always been an inherent part of the Post-Soviet realities within Central Asia. Since the collapse of the Soviet Union, Central Asia had to face numerous structural challenges including the management of the borders. Today when all five Central Asian countries are celebrating the 25th anniversary of their independence, there are significant border issues that remain unresolved and in most cases are overcomplicated. Over the years many disputed parts of the borders emerged, predominantly in the Fergana valley, where Kyrgyzstan, Tajikistan and Uzbekistan territories meet, converge and in some cases clash. All three Republics found themselves with some portion of the territory whose population could not identify itself with the host nation. What was once in fact a part of a single country run from Moscow that easily handled any slight ethnic territorial, political and economic tensions, now it is under the control of three different countries with different legislation, foreign policies and approaches to border management and regulation

  3. Ion induced changes in the structure of bordered pit membranes

    Full Text Available Xylem hydraulic resistance varies with ion concentration in sap solution. It is assumed that this variation in resistance results from hydrogel like properties of pectins located in bordered pit membranes separating adjacent vessels. Although kinetics of the resistance change suggests swelling/deswelling behavior of the pectins, there is no direct evidence of this activity. In this report we provide evidence of structural changes in bordered pit membranes responding to variation in ionic concentration of solute around it using atomic force microscopy (AFM. AFM revealed bordered pit membranes as relatively smooth, soft and lacking any sharp edges surface when submerged in de-ionized water, in contrast to pictures from scanning electron microscope (SEM or AFM performed on air dry material. Exposure of the bordered pit membranes to 50 mM KCl solution resulted in significant changes in both surface physical properties with and elevation features as bordered pit membrane became harder, with visible edges of fibers and collapsed, while no change in porosity was observed. Analysis suggests a need for a major shift in our understanding to the physical bases of variable xylem resistance from change in porosity to change in pathway length. Findings support the role of actuating properties of hybrid hydrogel-cellulose materials in water redistribution and embolism resistance.

    2012-04-01

    3-D assessment of scoliotic deformities relies on an accurate 3-D reconstruction of bone structures from biplanar X-rays, which requires a precise detection and matching of anatomical structures in both views. In this paper, we propose a novel semiautomated technique for detecting complete scoliotic rib borders from PA-0° and PA-20° chest radiographs, by using an edge-following approach with multiple-path branching and oriented filtering. Edge-following processes are initiated from user starting points along upper and lower rib edges and the final rib border is obtained by finding the most parallel pair among detected edges. The method is based on a perceptual analysis leading to the assumption that no matter how bent a scoliotic rib is, it will always present relatively parallel upper and lower edges. The proposed method was tested on 44 chest radiographs of scoliotic patients and was validated by comparing pixels from all detected rib borders against their reference locations taken from the associated manually delineated rib borders. The overall 2-D detection accuracy was 2.64 ± 1.21 pixels. Comparing this accuracy level to reported results in the literature shows that the proposed method is very well suited for precisely detecting borders of scoliotic ribs from PA-0° and PA-20° chest radiographs.

    To determine the age of immigration at which the marked increase in risk for alcohol- and drug-use problems in adulthood is observed among Mexican American adults residing in 2 distinct contexts: the U.S.-Mexico border, and cities not proximal to the border. We used 2 samples of Mexican American adults: specifically, 1,307 who resided along the U.S.-Mexico border, and 1,288 non-border adults who were interviewed as a part of the 2006 Hispanic Americans Baseline Alcohol Survey study. Survey logistic and Poisson regression methods were used to examine how immigration age during adolescence is related to alcohol- and drug-use behavior in adulthood. We found that participants who immigrate to the United States prior to age 14 have qualitatively different alcohol- and drug-related outcomes compared to those who immigrate later in life. Adults who immigrated at younger ages have alcohol- and drug-use patterns similar to those who were U.S.-born. Adults who immigrated at young ages and reside distal from the U.S.-Mexico border are at greater risk for alcohol and drug use than those who live in border contexts. Immigration from Mexico to the U.S. before age 14 results in alcohol- and drug-related behavior that mirrors the behavior of U.S.-born residents, and the alcohol- and drug-use effects were more pronounced among adults who did not reside proximal to the U.S.-Mexico border.

    2018-02-22

    Latin American social medicine efforts are typically understood as national endeavours, involving health workers, policymakers, academics, social movements, unions, and left-wing political parties, among other domestic actors. But Latin America's social medicine trajectory has also encompassed considerable between-country solidarity, building on early twentieth century interchanges among a range of players who shared approaches for improving living and working conditions and instituting protective social policies. Since the 1960s, Cuba's country-to-country solidarity has stood out, comprising medic exchanges, training, and other forms of support for the health and social struggles of oppressed peoples throughout Latin America and around the world, recently via Misión Barrio Adentro in Venezuela. These efforts strive for social justice-oriented health cooperation based on horizontal power relations, shared political values, a commitment to social and economic redistribution, bona fide equity, and an understanding of the societal determination of health that includes, but goes well beyond, public health and medical care. With Latin America's left-wing surge now receding, this article traces the provenance, dynamics, impact, challenges, and legacy of health solidarity across Latin American borders and its prospects for continuity.

  7. State borders in ETRS89 coordinates – reality or fiction ?

    Directory of Open Access Journals (Sweden)

    Jiří Poláček

    2015-12-01

    Full Text Available Common unique ETRS89 coordinates of the state boundaries are crucial for cross-border data harmonization for international projects. In the frame of European Location Framework (ELF project Czech Office for Surveying, Mapping and Cadastre (ČÚZK cooperates with Poland on egde-matching on the state border. During the preliminary phase of the project was some difficulty identified. If the state boundary is measured and administered in the national coordinate system, the accuracy of the transformation into the ETRS89 is influenced by discrepancies of the local trigonometric network, which results in two slightly different state boundaries. Final solution for Europe – international treaties on the state borders based on the ETRS89 coordinates – is necessary, but it will take years.

    The consumption of electricity by maquiladora industries in the Mexican border states is an important driver for determining future powerplant needs in that area. An industrial electricity forecasting model is developed for the border states' maquiladoras, and the outputs are compared with a reference forecasting model developed for the US industrial sector, for which considerably more data are available. This model enables the prediction of the effect of implementing various energy efficiency measures in the industrial sector. As an illustration, here the impact of implementing energy-efficient lighting and motors in the Mexican border states' maquiladoras was determined to be substantial. Without such energy efficiency measures, electricity consumption for these industries is predicted to rise by 64% from 2001 to 2010, but if these measures are implemented on a gradual basis over the same time period, electricity consumption is forecast to rise by only 36%.

    Full Text Available Border markets in many countries have been considered as the most important bridge for building a financial connection between inside and outside the countries. In this paper, we present an empirical study to find the impact of border market on customer satisfaction. The proposed study of this paper considers the effects of eight factors including competitive brand, foreign investment, management of imported goods, governmental supportive rules, monetary policies, supply chain management, buyers, marketing planning and import management on customer satisfaction who purchase on border markets. The proposed model of this paper designs and distributes 400 questionnaires among some experts and uses factor analysis and structural equation modeling to test nine hypotheses. The results indicate that there are some strong evidences that all nine factors impact customer satisfaction and foreign investment has the highest impact on customer satisfaction followed by supply chain management, marketing planning import management.

  11. MATRIX FOR COOPERATION IN THE CROSS-BORDER AREAS

    Directory of Open Access Journals (Sweden)

    Marcela ȘLUSARCIUC

    2014-06-01

    Full Text Available The crossborder areas have no constitutional competences, therefore most of the times they are not part of the decision making process in the agreements in cross-border relationships. Although the states are the ones to decide the policies and the agreements based on their own legal rules, considering the shape of the new European Union, they should more and more accept the conditionality of a regional overstate structure linked only to some geographical parts of the countries. The present paper proposes a theoretical and intuitive frame for assessing the cross-border areas based on the factors that are influencing it, starting from a listing of them, secondly grouping them in separating and uniting, then finding the significant differences. The matrix of factors can be used for conflict resolution or for development of cross-border areas as long as it shows the points that will be a potential obstacle or a source for cooperation.

  12. Displaced Borders: The Written Traumatic Borderline between Pskov Province and Chechnya

    Directory of Open Access Journals (Sweden)

    Mari Ristolainen

    2014-12-01

    Full Text Available This article examines the narrative construction of borders through an analysis of "non-professional writing" produced by the residents of Pskov. It discusses the construction of national borders and the symbolic meanings invested in them, with the empirical focus being placed on the symbolic Russian-Chechen border. The theoretical essence is the realization that due to the constructive and narrative na-tures of border production, the creation of a national borderline does not necessarily pre-suppose that the two sides share a geographical border. The article also addresses questions of traumatic memory and links border production with the concept of cultural trauma. By asking where Russia's borders currently located, this article provides an example of the cultural construction and symbolic displacement of the "national border", and a representation of how the national b/ordering processes differ when viewed from both "bottom up" and "top-down" perspectives in the contemporary Russian Federation.

  13. Conception of integrator in cross-border E-commerce

    Directory of Open Access Journals (Sweden)

    Arkadiusz Kawa

    2016-03-01

    Full Text Available Background:  E-commerce is one of the most dynamic and important sectors of the economy. The latest trend in this market is cross-border trade. It is based on selling products to customers who are located in other countries. However, it is connected to several problems, such as a high cost and long time of delivery, language barriers, different legal and tax conditionings, etc. Methods: The studies were conducted on the basis of the authors' experience in the field of e-commerce. The issue of cross-border commerce was mainly analysed with the use of reports of the European Commission. The aim of the article is to propose a conception of an integrator of cross-border e-commerce, which will make it possible, among other things, to solve logistic problems. Results: The article presents an authorial conception of an integrator in cross-border e-commerce. Its main task is to integrate the whole supply chain. Thanks to the economies of scale, obtained as a result of consolidation of parcels from many e-shops, the integrator is able to achieve lower delivery costs in international transport, make returns of goods more effective and serve customers from different countries better. Conclusions: The conception of an integrator in cross-border commerce proposed in the article may increase competitiveness of micro and small e-enterprises, especially in the international arena. Moreover, applying this conception may contribute to a rise in the attractiveness of cross-border commerce, which, as result of a greater sale level, would contribute to an increase in the total e-commerce.

    This paper explores the issue of 'fuel tourism' in Switzerland. For the period 1985-1997, a panel data model for the border regions of Switzerland, (Italy, France, and Germany) is estimated. The results show a significant impact of the gasoline price differential on demand, suggesting that a decrease of 10% in the Swiss gasoline price leads to an increase in demand in the border areas of nearly 17.5%. It is shown that fuel tourism accounted for about 9% of overall gasoline sales in the three regions during the period 1985-1997 and that the recently proposed Swiss CO 2 -tax might, given current conditions, eliminate net fuel tourism.

    2009-07-01

    Full Text Available Tamaulipas presents a long tradition of rural migration to the United States in search of farm employment. Until the eighties Tamaulipas’ undocumented workers crossed the border easily. However, from the nineties, as a result of a restrictive migration policy centered exclusively on the “supply–side” to cross the border has become intricate. As a result, most part of immigrants is using the services of “smuggles”. This paper analyses the impact of the militarization of the frontier on the emigration of Tamaulipas’ illegal rural workers seeking for farm jobs in the United States.

    Klempe, Sven Hroar

    2016-03-01

    This paper questions to what extent borders are to be understood from a philosophical or a psychological perspective. This is done by investigating the distinction between philosophy and psychology that comes up as a result of Immanuel Kant's investigation of the pure reason. Ontology is found as a demarcation criterion between the two fields in the sense that it is of crucial importance in philosophy, but not of certain interest from a psychological point of view. An investigation of three assumptions in the perspective of affective loading follows this up, which confirms the efficiency of borders in psychological meaning production.

At a mobile terminal the diversity can be increased by using transmit diversity techniques such as cyclic delay diversity (CDD and space-time coding like Alamouti. We transfer these transmit diversity techniques to a cellular environment. Therefore, the performance is enhanced at the cell border, intercellular interference is avoided, and soft handover procedures are simplified all together. By this, macrodiversity concepts are exchanged by transmit diversity concepts. These concepts also shift parts of the complexity from the mobile terminal to smart base stations.

    Booker, Paul M.; Maple, Scott A.

    2010-01-01

    Due to international commerce, cross-border conflicts, and corruption, a holistic, information driven, approach to border security is required to best understand how resources should be applied to affect sustainable improvements in border security. The ability to transport goods and people by land, sea, and air across international borders with relative ease for legitimate commercial purposes creates a challenging environment to detect illicit smuggling activities that destabilize national level border security. Smuggling activities operated for profit or smuggling operations driven by cross border conflicts where militant or terrorist organizations facilitate the transport of materials and or extremists to advance a cause add complexity to smuggling interdiction efforts. Border security efforts are further hampered when corruption thwarts interdiction efforts or reduces the effectiveness of technology deployed to enhance border security. These issues necessitate the implementation of a holistic approach to border security that leverages all available data. Large amounts of information found in hundreds of thousands of documents can be compiled to assess national or regional borders to identify variables that influence border security. Location data associated with border topics of interest may be extracted and plotted to better characterize the current border security environment for a given country or region. This baseline assessment enables further analysis, but also documents the initial state of border security that can be used to evaluate progress after border security improvements are made. Then, border security threats are prioritized via a systems analysis approach. Mitigation factors to address risks can be developed and evaluated against inhibiting factor such as corruption. This holistic approach to border security helps address the dynamic smuggling interdiction environment where illicit activities divert to a new location that provides less resistance

    2004-09-01

    Full Text Available Background. Objective evidence of cardiac dysfunction is one of the diagnostic criteria for heart failure. It is often hard to assess systolic function and assessing diastolic dysfunction is even harder because there are no generally accepted echocardiographic criteria. Tissue Doppler imaging (TDI enables analysis of the mitral annular descent velocity for detection of left ventricular diastolic dysfunction along the longitudinal axis.Methods. 30 patients with heart failure and 30 healthy participants were enrolled in the study. Pulsed wave tissue Doppler imaging velocities of septal and lateral mitral annulus borders were recorded in systole (Sm and early diastole (Em. Velocities in both groups were compared. The correlations between Sm velocity and LVEF and Em velocity and age were studied.Results. Patients with heart failure had significantly decreased Sm and Em velocities compared with healthy participants (5.3 ± 1.6 cm/s vs. 8.4 ± 1 cm/s, P < 0.001, for Sm velocity and 5 ± 1.4 cm/s vs. 8.7 ± 1.6 cm/s, P < 0.001, for Em velocity. The correlation between Sm velocity and LVEF in all participants was very good and highly significant (r = 0.91, P < 0.001. The Sm velocity ≥ 6.4 cm/s was 91% sensitive and 95% specific for LVEF ≥ 0.45. There was a good correlation between age and Em velocity (r = -0.84, P < 0.001. The Em velocity < 7 cm/s had a sensitivity of 90% and specificity of 97% for diagnosing heart failure.Conclusions. Pulsed wave tissue Doppler imaging of mitral annulus enables simple, fast and precise assessment of systolic and diastolic left ventricular function. It can replace some other more time consuming echocardiographic measurements.

    Full Text Available The border area between Brazil, Colombia, and Peru has a population of over 100,000 people; at least a quarter are indigenous (mostly Tikuna, and the rest is composed of people from the Andean region and some itinerant groups (migrants, traders, etc.. The “twin cities”, Tabatinga (Brazil and Leticia (Colombia, receive a significant flux of people from the adjacent regions of each country, each one having a referral hospital for attending cases of moderate complexity. This region has a high incidence of  water-borne diseases, such as diarrhea and hepatitis, those transmitted by vectors, such as malaria and leishmaniasis, and other infectious diseases related to living conditions and the level of access to the health system, such as sexually transmitted infections, tuberculosis, and Hansen’s disease.. This work presents attempts to carry out a global analysis of the prevalence of some health problems introduced into the area during the last two decades, such as cholera epidemics, malaria, and HIV/AIDS infection, attempting to describe their main determinants in the region.

  7. Compression syndrome of the left renal vein

    Justich, E.

    1982-04-01

    Severe compression of the left renal vein produces a pressure gradient between it and the inferior vena cava and results in changes in haemodynamics. The cause of the narrowing is usually the aorta, less commonly the superior mesenteric artery. Compression of the left renal vein may be responsible for a number of abnormalities such as primary varicoceles, primary varices of the ovarian, renal, pelvic and ureteric veins on the left, the more frequent occurrence of unilateral renal vein thrombosis on the left and the development of renovascular hypertension. One hundred and twenty-three selective phlebograms of the left renal vein and CT examinations of this structure in a further 87 patients acting as a control group were carried out. The significance of compression of the left renal vein as an aetiological factor in the development of the above mentioned abnormalities is discussed.

  8. Multiplicativity of left centralizers forcing additivity

    Full Text Available A multiplicative left centralizer for an associative ring R is a map satisfying T(xy = T\\(xy for all x,y in R. T is not assumed to be additive. In this paper we deal with the additivity of the multiplicative left centralizers in a ring which contains an idempotent element. Specially, we study additivity for multiplicative left centralizers in prime and semiprime rings which contain an idempotent element.

  9. MR image analysis: Longitudinal cardiac motion influences left ventricular measurements

    Berkovic, Patrick; Hemmink, Maarten; Parizel, Paul M.; Vrints, Christiaan J.; Paelinck, Bernard P.

    2010-01-01

    Background: Software for the analysis of left ventricular (LV) volumes and mass using border detection in short-axis images only, is hampered by through-plane cardiac motion. Therefore we aimed to evaluate software that involves longitudinal cardiac motion. Methods: Twenty-three consecutive patients underwent 1.5-Tesla cine magnetic resonance (MR) imaging of the entire heart in the long-axis and short-axis orientation with breath-hold steady-state free precession imaging. Offline analysis was performed using software that uses short-axis images (Medis MASS) and software that includes two-chamber and four-chamber images to involve longitudinal LV expansion and shortening (CAAS-MRV). Intraobserver and interobserver reproducibility was assessed by using Bland-Altman analysis. Results: Compared with MASS software, CAAS-MRV resulted in significantly smaller end-diastolic (156 ± 48 ml versus 167 ± 52 ml, p = 0.001) and end-systolic LV volumes (79 ± 48 ml versus 94 ± 52 ml, p < 0.001). In addition, CAAS-MRV resulted in higher LV ejection fraction (52 ± 14% versus 46 ± 13%, p < 0.001) and calculated LV mass (154 ± 52 g versus 142 ± 52 g, p = 0.004). Intraobserver and interobserver limits of agreement were similar for both methods. Conclusion: MR analysis of LV volumes and mass involving long-axis LV motion is a highly reproducible method, resulting in smaller LV volumes, higher ejection fraction and calculated LV mass.

    Left ventricular (LV) thrombi are rarely recognized during life, though they are not infrequent at the post-mortem examination of patients succumbed to valvular disease, acute myocardial infarction, and cardiomyopathy. We presented five cases in which LV thrombi were detected by cross-sectional echocardiography (CSE) and confirmed by computed tomography. The main purpose of this study was to compare the echocardiographic findings of the LV thrombi with the manifestations of the LV thrombi on the computed tomograms, with a hope to augment the clinical utility of CSE in the detection of LV thrombi. CSE was recorded from the apical and four-chamber views in addition to the conventional approach. A computed tomographic whole-body scanner which utilized a continuously rotating gantry and pulsed anode with X-ray radiation collimated to form a thin fan-shaped beam was used. A complete section scan was performed in 3 seconds. Sustained enhancement was obtained with a rapid intravenous infusion of 30% meglumine iothalanate. Most of the LV thrombi showed an abnormal echo with irregular borders and/or a mobile mass echo at the apex by CSE. Computed tomographic findings suggestive of LV thrombi appeared as a defect, which was apparently different in quality from the surrounding myocardium or valvular apparatus. These findings were quite consistent with those of CSE with respect to the number and the location of the LV thrombi.

  11. Anarchy, socialism and a Darwinian left.

    Science.gov (United States)

    Clarke, Ellen

    2006-03-01

    In A Darwinian left Peter Singer aims to reconcile Darwinian theory with left wing politics, using evolutionary game theory and in particular a model proposed by Robert Axelrod, which shows that cooperation can be an evolutionarily successful strategy. In this paper I will show that whilst Axelrod's model can give support to a kind of left wing politics, it is not the kind that Singer himself envisages. In fact, it is shown that there are insurmountable problems for the idea of increasing Axelrodian cooperation within a welfare state. My surprising conclusion will be that a Darwinian left worthy of the name would be anarchistic.

    The article looks at New Labour's move beyond right/left in the mid/late 1990s, which is an occasion to spell out the nature of right/left and what it means for democracy. In contrast to both defenders and critics of this move I argue in the first part that right/left is not an empty label bound up...... right/left. I argue that the new hegemonic orientation is that of front/back, which designs political renewal as a response to the social changes cutting across the outdated lines of contestation of partisan politics. The democratic problem of this move lies in squeezing politics between technocratic...

  14. Problems concerned with scrap metal monitoring at borders

    International Nuclear Information System (INIS)

    Duftschmid, K.E.

    1997-01-01

    Since the early 1980's numerous incidents have been reported in which radioactive material or empty labelled containers for radioactive sources have been found in scrap metal. Apart from the potential health hazard to employees and the general public resulting costs for decontamination, shutdown of production and waste of products already amounted to multi-million dollar figures. Since the opening of the ''iron border'' in Europe, incidents of illicit trafficking of radioactive sources across borders and contamination of scrap metal imported from the former ''Eastern Countries'' have considerably increased, as a result of the lack of a suitable radiation protection infrastructure in some of these countries. This initiated monitoring of scrap metal transports at the borders of several European countries, such as Austria, Finland, Germany and Italy. Up to now neither universally accepted clearance levels for scrap contamination, nor an agreed standardised procedure for its control exist, although the IAEA as well as the European Commission have proposed some recommendations. As a pragmatic solution for border monitoring it is suggested to apply, as practical clearance level, a dose rate on the outside of the vehicle in the order of 0,1 μSv/h, which is approximately equivalent to double natural environmental background. This dose rate would correspond to an activity concentration for 60 Co in the order of 1 kBq/kg and therefore be in a tolerable range, even in view of products coming in close contact with the public.

  15. Border adjustment for European emissions trading: Competitiveness and carbon leakage

    Energy Technology Data Exchange (ETDEWEB)

    2010-04-15

    Unilateral or sub-global policies to combat climate change are potentially sensitive to free-riding and carbon leakage. One way of dealing with carbon leakage and competitiveness is the imposition of border adjustment measures for competing imports, for example in the form of the obligation to importers of goods to purchase and surrender emissions allowances to the authorities when importing. In this paper, we explore some implications of border adjustment measures in the EU ETS, for sectors that might be subject to carbon leakage. We examine the implications of two variants of these measures on the competitiveness of these sectors and on the global environment with the help of a multi-sector, multi-region computable general equilibrium (CGE) model of the global economy. Our calculations suggest that border adjustment might reduce the sectoral rate of leakage of the iron and steel industry rather forcefully, but that the reduction would be less for the mineral products sector, including cement. The reduction of the overall or macro rate of leakage would be modest. So, from an environmental point of view border tax adjustments would not be a very effective policy measure, but might mainly be justified by considerations of sectoral competitiveness.

    2014-07-01

    This paper studies the cross-border health and productivity effects of alcohol taxes. We estimate the effect of a large cut in the Finnish alcohol tax on mortality, alcohol-related illnesses and work absenteeism in Sweden. This tax cut led to large differences in the prices of alcoholic beverages between these two countries and to a considerable increase in cross-border shopping. The effect is identified using differences-in-differences strategy where changes in these outcomes in regions near the Finnish border are compared to changes in other parts of northern Sweden. We use register data where micro level data on deaths, hospitalisations and absenteeism is merged to population-wide micro data on demographics and labour market outcomes. Our results show that the Finnish tax cut did not have any clear effect on mortality or alcohol-related hospitalisations in Sweden. However, we find that workplace absenteeism increased by 9% for males and by 15% for females near the Finnish border as a result of the tax cut. Copyright © 2014 Elsevier B.V. All rights reserved.

  8. Mobile surveillance units (MSU) for border protection and homeland defense

    2003-09-01

    During the last 12 years the European Union (EU) has financed the new member applicant countries of Central and Eastern Europe in their preparation for joining the EU. Based on this enlargement of the EU, funding for border protection has been made available from the overall infrastructure improvement budget. Border protection was required in areas where border conflicts had taken place and to limit illegal immigration and smuggling. After 9/11 defence against terrorist activities will no doubt be added to the requirement. This paper describes the approach taken in the provision of police and para-military Mobile Surveillance Units (MSU's). This approach may also be considered for the US Homeland Defense initiative. These MSU's utilize standard road vehicles converted to use high performance military thermal imagers, such as SiGMA. In future the current, in service, MSU will require increased sensor integration and networking to cover land and coastal borders. The underlying key is affordability for the police and para-military markets while retaining the highest performance derived from the latest military standard thermal imagers.

    Full Text Available This paper analyses the impact of the economic and financial crisis on merger and acquisition activity in Europe and the latest trends manifested on the cross-border merger and acquisition market involving European companies. Thus, a first objective of this research is to reveal the evolution of the European cross-border merger and acquisition activity in terms of dynamics, volume and structure. Another objective of this research is to reveal the short and medium term perspectives on mergers and acquisitions in Europe. Thus, under the continuous economic recovery of the European countries and the other worldwide economies, the recovery of financial markets and the growth of corporate profits, we shall witness an intensive cross-border merger and acquisition activity in Europe. The expansion engine of these operations seems to be represented by the emerging economies. This research is based on a systematic, logical and comparative analysis of scientific literature and statistical data regarding the cross-border mergers and acquisitions that involve European companies in recent years.

  20. How Neighbours Communicate: The Role of Language in Border Relations

    Directory of Open Access Journals (Sweden)

    Sonni Olsen

    2014-10-01

    Full Text Available This paper reports on a study of the linguistic situation in the border region where Norway meets Russia in the north. The aim of the study was to investigate language use when contact is revitalised after a long period with closed borders. The Norwegian and Russian languages are very different in vocabulary and structure, which makes communication difficult. How are the two languages affected by extended contact and migration across the border? The study was carried out by the author and Marit Bjerkeng through interviews, a questionnaire and observation of the linguistic situations in two Norwegian communities. The results show an ongoing development where the neighbouring language is increasingly noticeable, and there is a clear link between attitudes, identity and language use. The role of public policy seems to play an important role for the developing linguistic situation, as the Barents region as a political concept introduced in the 1990s has led to cross-border contact within various fields and also inspired local language policy, contributing to cultural pride an

    In the last decade, a disorder characterized by episodes of involuntary movements and dystonia has been recognized in Border Terriers. To define clinical features of paroxysmal dyskinesia (PD) in a large number of Border Terriers and to study the genetics of the disease. 110 affected and 128 unaffected client-owned Border Terriers. A questionnaire regarding clinical characteristics of PD was designed at Utrecht University and the University of Helsinki. Thirty-five affected Border Terriers underwent physical examination and blood testing (hematology and clinical biochemistry). Diagnostic imaging of the brain was performed in 17 affected dogs and electroencephalograms (EEG) between episodes were obtained in 10 affected dogs. A genomewide association study (GWAS) was performed with DNA of 110 affected and 128 unaffected dogs. One hundred forty-seven questionnaires were included in the study. The most characteristic signs during episodes were dystonia, muscle fasciculations, and falling over. The majority of owners believed that their dogs remained conscious during the episodes. A beneficial effect of anti-epileptic therapy was observed in 29 of 43 dogs. Fifteen owners changed their dogs' diet to a hypoallergenic, gluten-free diet, and all reported reasonable to good improvement of signs. Clinical examinations and diagnostic test results were unremarkable. The GWAS did not identify significantly associated chromosome regions. The survey results and EEG studies provided further evidence that the observed syndrome is a PD rather than epilepsy. Failure to achieve conclusive results by GWAS indicates that inheritance of PD in Border Terriers probably is complex. Copyright © 2017 The Authors.

    Detergent-insoluble complexes prepared from pig small intestine are highly enriched in several transmembrane brush border enzymes including aminopeptidase N and sucrase-isomaltase, indicating that they reside in a glycolipid-rich environment in vivo. In the present work galectin-4, an animal lectin lacking a N-terminal signal peptide for membrane translocation, was discovered in these complexes as well, and in gradient centrifugation brush border enzymes and galectin-4 formed distinct soluble high molecular weight clusters. Immunoperoxidase cytochemistry and immunogold electron microscopy showed that galectin-4 is indeed an intestinal brush border protein; we also localized galectin-4 throughout the cell, mainly associated with membraneous structures, including small vesicles, and to the rootlets of microvillar actin filaments. This was confirmed by subcellular fractionation, showing about half the amount of galectin-4 to be in the microvillar fraction, the rest being associated with insoluble intracellular structures. A direct association between the lectin and aminopeptidase N was evidenced by a colocalization along microvilli in double immunogold labeling and by the ability of an antibody to galectin-4 to coimmunoprecipitate aminopeptidase N and sucrase-isomaltase. Furthermore, galectin-4 was released from microvillar, right-side-out vesicles as well as from mucosal explants by a brief wash with 100 mM lactose, confirming its extracellular localization. Galectin-4 is therefore secreted by a nonclassical pathway, and the brush border enzymes represent a novel class of natural ligands for a member of the galectin family. Newly synthesized galectin-4 is rapidly "trapped" by association with intracellular structures prior to its apical secretion, but once externalized, association with brush border enzymes prevents it from being released from the enterocyte into the intestinal lumen.

    Border area is geographically adjacent to neighboring countries with the primary function of maintaining state sovereignty and public welfare. Area in question is part of the provinces, districts or cities that directly intersect with national boundaries (or territory) and / or that have a functional relationship (linkage) and has a strategic value for the state. The border area is considered strategic because it involves the national lives of many people in terms of the interests of political, economic, social and cultural as well as defense and security (poleksosbudhankam) both located on land, sea or air. The border area is geographically adjacent to neighboring countries with the primary function of maintaining state sovereignty and public welfare. Area in question is part of the provinces, districts or cities that directly intersect with national boundaries (or territory) and / or that have a functional relationship (linkage) and has a strategic value for the state. To realize the necessary research on the development of the area, based on good practices from other countries some of the city that can meet all these challenges and at least can be applied with minor changes / adjustments. Furthermore, the application must be supported by the availability of funds. This study to discuss about any problems either obstacles or things that drive to develop function becomes an ideal border area with major support infrastructure for housing, transportation, energy availability, and distribution of clean water which will strengthen in its function which consists of five pillars, namely: central community service; trade and distribution center; financial center; tourism center; related to the field of community development. Articulation between key stakeholders such as government, private, and community is a major concern in this study, including in determining the appropriate financing schemes. The results of this study will be recommended to the government to improve

  10. Crossing and Passing: Discursive Borders in Off Shoring

    Full Text Available As a term in popular discourse, globalisation marks a celebrated openness of global spaces. Critics of globalisation argue that a global economy creates borders that are more discursive than territorial. A current challenge to globalisation scholars is reaching an understanding of how the many configurations of context, space, time and place created by globalisation result in new ways of organizing space and identity. Based on rich ethnographic data from an off shore call centre in Morocco and informed by interdisciplinary research on space, this paper bridges the links between territorial and discursive borders in the global social network of off shoring. Metaphorical spaces come about when dynamic configurations of contexts at territorial borders relate or are made to relate. Call centre agents use metaphorical spaces to fix the meaning of space. In this article, I identify two different metaphorical spaces: crossing and passing that help agents organize and negotiate their spaces and subsequently their identities and power relations. I suggest that agents negotiate place through space. This crossing takes place as they imbricate the Moroccan context of “L’hrig” within the continuum of the call centre. I also suggest that agents negotiate space through place. This passing occurs via the imbrication of metaphorical space of polyvalence. Crossing and passing inscribe not only a literal meaning of “movement” and “disembodiment”, but also the nuanced meaning of “movement and staying” and “disembodiment and re-embodiment” in a place where conjunctions of space, time, place and context collide. The creation of metaphorical spaces of crossing and passing suggests modification of our understanding of diaspora: attaining the diasporic space can no longer depend on physical borders alone; it must also rely on discursive borders.

  11. A Voice of the US Southwestern Border: The 2012 “We the Border: Envisioning a Narrative for Our Future” Conference

    Full Text Available In July 2012, a diverse group of US residents living near the US-Mexico border met in El Paso, Texas for a conference entitled, We the Border: Envisioning a Narrative for Our Future.  This paper describes a vision for the US-Mexico border by diverse border residents that is at odds with the widespread view of the border as a threat to the United States. These border residents viewed their region as a set of human communities with rights, capacities, and valuable insights and knowledge. They embraced an alternative vision of border enforcement that would focus on “quality” (dangerous entrants and contraband over “quantity” (mass migration enforcement.  They called for investments in the functionality and security of ports of entry, rather than in between ports of entry.  They noted the low crime rate in US border cities, and examined how policies of not mixing local law enforcement with federal immigration enforcement contributed to this achievement. They saw the border region as the key transportation and brokerage zone of the emerging, integrated North American economy. In their view, the bilingual, bicultural, and binational skills that characterize border residents form part of a wider border culture that embraces diversity and engenders creativity. Under this vision the border region is not an empty enforcement zone, but is part of the national community and its residents should enjoy the same constitutional and human rights as other US residents. The conference participants emphasized the necessity and value of accountability and oversight of central government enforcement operations, and the need for border communities to participate in federal decision-making that affects their lives.

  13. Border screening vs. community level disease control for infectious diseases: Timing and effectiveness

    There have been many studies of the border screening using a simple math model or a statistical analysis to investigate the ineffectiveness of border screening during 2003 and 2009 pandemics. However, the use of border screening is still a controversial issue. It is due to focusing only on the functionality of border screening without considering the timing to use. In this paper, we attempt to qualitatively answer whether the use of border screening is a desirable action during a disease pandemic. Thus, a novel mathematical model with a transition probability of status change during flight and border screening is developed. A condition to check a timing of the border screening is established in terms of a lower bound of the basic reproduction number. If the lower bound is greater than one, which indicates a pandemic, then the border screening may not be effective and the disease persists. In this case, a community level control strategy should be conducted.

    Type 2 diabetes mellitus (DM) is a re-emerging risk factor for TB development and adverse TB outcomes. As a follow-up of our previous study in 1998-2004, we reassessed prevalence of DM and its associated factors among 8431 TB patients using surveillance data from 2006 to 2013 for the Mexican state of Tamaulipas, across the border with Texas. Prevalence of DM was 25.2%, with an increase of at least 2.8% over the study period. Newly discovered factors associated with TB-DM (versus no DM) were lower education and higher unemployment (p < 0.001), which are reportedly associated with poorer DM management. At least 15% of the DM patients were newly-diagnosed and younger than those previously diagnosed, showing the importance of early DM diagnosis at TB clinics. TB-DM patients were more likely to have smear-positive, pulmonary (versus extra-pulmonary) and drug-resistant TB (1.9-, 3.8- and 1.4-fold, respectively). During treatment, TB-DM patients were more likely to be smear-positive, and less likely to die or abandon TB treatment. Thus, the increasing prevalence of DM among TB, and its association with low education, features of a more contagious TB, and drug resistance, highlight the need for design of TB management programs in DM patients, blood testing of all new TB patients for DM, and if positive for DM, testing for drug resistance.
