Combating Statelessness in the Wake of the Syrian Conflict: A Right without a Remedy

In the wake of the Syrian Civil War, millions of persons have been displaced from their homes. As desperate families flee zones of conflict, they leave all but their most precious belongings behind, in search of safety in neighboring countries. The path to safety and security, however, is a dangerous one. Displaced persons must traverse national borders, military checkpoints, and journey great distances to find safe haven. Unfortunately, Syrian families often do not carry identification documents to establish a legal recognition of their nationality in foreign lands. Consequently, this population of refugees is left vulnerable to the ugly reality of statelessness. First, this Note resolves to acknowledge the magnitude of the statelessness issue in the wake of the largest humanitarian crisis in the past two decades. Second, this Note emphasizes that, though the normative humanitarian framework established by human rights Conventions in the twentieth century theoretically acknowledges a universal right to nationality, the practical reality is that massive populations of displaced persons are left without a remedy. This Note seeks to emphasize that there are inherent tensions between sovereign authority over citizenship determinations and humanitarian norms that have achieved customary character. Because the normative framework of the twentieth century has come to favor human rights, this Note seeks to illustrate that there exists an obligation on nation-states to, minimally, avoid the creation of stateless persons. In light of the fundamental connection between citizenship and the rights, protections, and privileges that flow forth from its possession, this Note argues that obligations under customary international law that exist for the protection of guaranteed human dignities should be honored, and domestic legislation that obstructs these obligations must be modified

Untersuchung zur pharmakologischen Aktivierung arterieller KCa3.1-Kanäle durch SKA-31.

Die EDHF-Antwort ist neben NO und PGI2 der dritte Hauptweg der endothelvermittelten Vasodilatation und eine selektive Öffnung des KCa3.1 Kanals könnte den Ansatzpunkt für eine neue Strategie zur Blutdrucksenkung darstellen (Feletou & Vanhoutte 2006, Sankaranarayanan et al. 2009). Im Speziellen wurde an A.c.c. von Wildtyp- (KCa3.1+/+) und Knockouttieren (KCa3.1-/-) der Einfluss von SKA-31 auf die durch Azetyllcholin induzierte Vasodilatation untersucht. Ebenfalls war es Ziel zu überprüfen, ob SKA-31 einen Einfluss auf die durch Phenylephrin und hohe Kaliumkonzentration induzierte Vasokonstriktion hat. Die Ergebnisse der Untersuchungen zeigen, dass SKA-31 die EDHF-vermittelte Vasodilatation deutlich potenziert und eine hohe Selektivität für den KCa 3.1 Kanal besitzt. Auf die glattmuskuläre Funktion bestand kein Einfluss

Legal Terms of Use and Public Genealogy Websites

Public genealogy websites, to which individuals upload family history, genealogy, and sometimes individual genetic data, have been used in an increasing number of public health, epidemiological, and genetic studies. Yet there is little awareness among researchers of the legal rules that govern the use of these online resources. We analyzed the online Terms of Use (TOU) applicable to 17 popular genealogy websites and found that none of them expressly permit scientific research, while at least 13 contain restrictions that may limit or prohibit scientific research using data obtained from those sites. In order to ensure that researchers who use genealogy and other data from these sites for public health and other scientific research purposes do not inadvertently breach applicable TOUs, we recommend that genealogy website operators consider revising their TOUs to permit this activity

Patient-specific image-based computer simulation for theprediction of valve morphology and calcium displacement after TAVI with the Medtronic CoreValve and the Edwards SAPIEN valve

AIMS: Our aim was to validate patient-specific software integrating baseline anatomy and biomechanical properties of both the aortic root and valve for the prediction of valve morphology and aortic leaflet calcium displacement after TAVI. METHODS AND RESULTS: Finite element computer modelling was performed in 39 patients treated with a Medtronic CoreValve System (MCS; n=33) or an Edwards SAPIEN XT (ESV; n=6). Quantitative axial frame morphology at inflow (MCS, ESV) and nadir, coaptation and commissures (MCS) was compared between multislice computed tomography (MSCT) post TAVI and a computer model as well as displacement of the aortic leaflet calcifications, quantified by the distance between the coronary ostium and the closest calcium nodule. Bland-Altman analysis revealed a strong correlation between the observed (MSCT) and predicted frame dimensions, although small differences were detected for, e.g., Dmin at the inflow (mean±SD MSCT vs. MODEL: 21.6±2.4 mm vs. 22.0±2.4 mm; difference±SD: -0.4±1.3 mm, p<0.05) and Dmax (25.6±2.7 mm vs. 26.2±2.7 mm; difference±SD: -0.6±1.0 mm, p<0.01). The observed and predicted calcium displacements were highly correlated for the left and right coronary ostia (R2=0.67 and R2=0.71, respectively p<0.001). CONCLUSIONS: Dedicated software allows accurate prediction of frame morphology and calcium displacement after valve implantation, which may help to improve outcome

Recommendations for sepsis management in resource-limited settings

PURPOSE: To provide clinicians practicing in resource-limited settings with a framework to improve the diagnosis and treatment of pediatric and adult patients with sepsis. METHODS: The medical literature on sepsis management was reviewed. Specific attention was paid to identify clinical evidence on sepsis management from resource-limited settings. RESULTS: Recommendations are grouped into acute and post-acute interventions. Acute interventions include liberal fluid resuscitation to achieve adequate tissue perfusion, normal heart rate and arterial blood pressure, use of epinephrine or dopamine for inadequate tissue perfusion despite fluid resuscitation, frequent measurement of arterial blood pressure in hemodynamically unstable patients, administration of hydrocortisone or prednisolone to patients requiring catecholamines, oxygen administration to achieve an oxygen saturation &gt;90%, semi-recumbent and/or lateral position, non-invasive ventilation for increased work of breathing or hypoxemia despite oxygen therapy, timely administration of adequate antimicrobials, thorough clinical investigation for infectious source identification, fluid/tissue sampling and microbiological work-up, removal, drainage or debridement of the infectious source. Post-acute interventions include regular re-assessment of antimicrobial therapy, administration of antimicrobials for an adequate but not prolonged duration, avoidance of hypoglycemia, pharmacological or mechanical deep vein thrombosis prophylaxis, resumption of oral food intake after resuscitation and regaining of consciousness, careful use of opioids and sedatives, early mobilization, and active weaning of invasive support. Specific considerations for malaria, puerperal sepsis and HIV/AIDS patients with sepsis are included. CONCLUSION: Only scarce evidence exists for the management of pediatric and adult sepsis in resource-limited settings. The presented recommendations may help to improve sepsis management in middle- and low-income countries

Urinary p75(ECD): A prognostic, disease progression, and pharmacodynamic biomarker in ALS.

OBJECTIVE: To evaluate urinary neurotrophin receptor p75 extracellular domain (p75(ECD)) levels as disease progression and prognostic biomarkers in amyotrophic lateral sclerosis (ALS). METHODS: The population in this study comprised 45 healthy controls and 54 people with ALS, 31 of whom were sampled longitudinally. Urinary p75(ECD) was measured using an enzyme-linked immunoassay and validation included intra-assay and inter-assay coefficients of variation, effect of circadian rhythm, and stability over time at room temperature, 4°C, and repeated freeze-thaw cycles. Longitudinal changes in urinary p75(ECD) were examined by mixed model analysis, and the prognostic value of baseline p75(ECD) was explored by survival analysis. RESULTS: Confirming our previous findings, p75(ECD) was higher in patients with ALS (5.6 ± 2.2 ng/mg creatinine) compared to controls (3.6 ± 1.4 ng/mg creatinine, p < 0.0001). Assay reproducibility was high, with p75(ECD) showing stability across repeated freeze-thaw cycles, at room temperature and 4°C for 2 days, and no diurnal variation. Urinary p75(ECD) correlated with the revised ALS Functional Rating Scale at first evaluation (r = -0.44, p = 0.008) and across all study visits (r = -0.36, p < 0.0001). p75(ECD) also increased as disease progressed at an average rate of 0.19 ng/mg creatinine per month (p < 0.0001). In multivariate prognostic analysis, bulbar onset (hazard ratio [HR] 3.0, p = 0.0035), rate of disease progression from onset to baseline (HR 4.4, p < 0.0001), and baseline p75(ECD) (HR 1.3, p = 0.0004) were predictors of survival. CONCLUSIONS: The assay for urinary p75(ECD) is analytically robust and shows promise as an ALS biomarker with prognostic, disease progression, and potential pharmacodynamic application. Baseline urinary p75(ECD) provides prognostic information and is currently the only biological fluid-based biomarker of disease progression
