description: Graphs with high symmetry or regularity are the main source for experimentally hard instances of the notoriously difficult graph isomorphism problem. In this paper, we study the computational complexity of isomorphism testing for line graphs of $t$-$(v,k,λ)$ designs. For this class of highly regular graphs, we obtain a worst-case running time of $O(v^{\log v + O(1)})$ for bounded parameters $t,k,λ$. In a first step, our approach makes use of the Babai--Luks algorithm to compute canonical forms of $t$-designs. In a second step, we show that $t$-designs can be reconstructed from their line graphs in polynomial-time. The first is algebraic in nature, the second purely combinatorial. For both, profound structural knowledge in design theory is required. Our results extend earlier complexity results about isomorphism testing of graphs generated from Steiner triple systems and block designs.

description: The tumor suppressor CYLD is a deubiquitinating enzyme that acts as a negative regulator of several signaling pathways including NF-kappa-B and MAPK activation pathways, by affecting the function of important mediators. CYLD regulates several cellular processes such as immune responses, inflammation, cell survival, proliferation and differentiation. The tumor suppressor function of CYLD seems to be cell-type specific and it is important to delineate its involvement in the homeostasis of specific tissues in order to understand and exploit its role in oncogenesis . In this review, we summarize existing data on the expression and alterations of CYLD in certain types of lung and colorectal neoplasias.

description: Purpose – This paper aims to report on the development of a model to improve process health and safety within the context of a petrochemical environment to achieve a generative health and safety culture within that sector. Design/methodology/approach – A quantitative research methodology and deductive research approach were used in the study. A survey was conducted in a major petrochemical enterprise in the KwaZulu-Natal province of South Africa with 259 returned and duly completed questionnaires. The data was statistically analysed using statistical packages for social science version 25. Findings – This study found that the key process health and safety critical drivers needed to grow a generative process health and safety culture were leadership commitment, chemical exposure management, health and safety risk assessment, process hazard analysis and permit to work. Research limitations/implications – This study was conducted in the KwaZulu-Natal Province of South Africa within the petrochemical industry. Because of self-reported methods of data collection, there is a probability of bias existing in the results of the study. Practical implications – The contribution of this research is to understand, based on theoretical assumptions, how health and safety improvement could be institutionalised in an organisation. The developed model can be used as a practical tool. Social implications – This paper is part of the larger discussion of increasing importance in health and safety policy-making. This study aims at contributing to the literature in the field of health and safety by incorporating the drivers towards a generative process health and safety culture. Originality/value – This study provides a model to assist senior management to reduce exposure to process health and safety hazards in the petrochemical industry and improve overall performance.

description: Using a recent catalogue of extragalactic Faraday rotation derived from the NRAO VLA Sky Survey we have found an agreement between Faraday rotation structure and the HI emission structure of a High Velocity Cloud (HVC) associated with the Leading Arm of the Magellanic System. We suggest that this morphological agreement is indicative of Faraday rotation through the HVC. Under this assumption we have used 48 rotation measures through the HVC, together with estimates of the electron column density from H-α measurements and QSO absorption lines to estimate a strength for the line-of-sight component of the coherent magnetic field in the HVC of > 6 {\rm μG}$. A coherent magnetic field of this strength is more than sufficient to dynamically stabilize the cloud against ram pressure stripping by the Milky Way halo and may also provide thermal insulation for the cold cloud. We estimate an upper limit to the ratio of random to coherent magnetic field of $B_{r}/B_{||} < 0.8$, which suggests that the random field does not dominate over the coherent field as it does in the Magellanic Clouds from which this HVC likely originates.

description: In recent years the census of known satellites in our own Local Group and in nearby galaxy groups has increased substantially due to sensitive wide-area surveys. In the Local Group these surveys have more than doubled its known galaxy content and extended the galaxy luminosity function to very faint total magnitudes. Deep ground-based imaging and spectroscopic observations as well as high-resolution imaging with the Hubble Space Telescope have revolutionized our understanding of the chemical evolution and star formation histories of the satellites. We often find long-lasting star formation episodes with low star formation efficiencies. There is evidence for localized, stochastic enrichment, and recent searches are now beginning to uncover even extremely metal-deficient stars. In many satellites evidence for two or more distinct stellar subpopulations is found. Differing fractions of old populations have been detected in all satellites studied in sufficient detail so far. Kinematic measurements support a picture in which satellites are dark-matter dominated, although recent results indicate that the proposed common mass scale for dwarf spheroidal galaxies may not hold for very low-mass satellites. When considering satellite ensembles, we find global morphology-distance and gas-content - distance relations in all groups studied thus far, but individual star formation histories also strongly depend on a given satellite's intrinsic properties.

description: Hereditary pancreatitis (HP) is a rare genetic disorder characterized by acute recurrent pancreatitis (ARP) and chronic pancreatitis (CP) that runs in families. It’ s symptoms are usually typical ones pancreatitis but HP is more amenable to treatment, especially when complication presents. Recent single-center studies have identified several genetic risk factors, including cystc fibrosis transmembrane conductance regulator (CFTR), cationic trypsinogen (PRSS1), pancreatic secretory trypsin inhibitor (SPINK1), chymotrypsin (CFTP) and carboxypeptidase 1 (CPA1) genes. Other risk factors include obstructive, traumatic, infectious and systemic causes. Our case report presents a 9-years old boy, with a pancreatic pseudocyst (8cm in diameter) as a consequence of recurrent episodes of pancreatitis. The diagnostic investigation (MRCP, Cystic Fibrosis test) had proved no obvious aetiology. An enterocystic roux en Y anastomosis was performed, but the boy continued o develop episodes of pancreatitis and after 2 years, he presented with a new pancreatic pseudocyst (PPC) of the same dimensions, which was attributed to genetic factors. A more conservative approach was decided: endoscopic transgastric drainage of the pseudocyst. In gastroscopy, the cyst was protruded on the posterior wall of the stomach and it was drained into it via a pig tail catheter, which was removed 6 weeks later. After 3 months abdominal ultrasonography follow up confirms the successful drainage of the pseudocyst.

description: Lung cancer (LC) is the leading cause of cancer deaths worldwide. Several new treatments have become available in recent decades, but little research exists on the impact of these on productivity, early retirement and survival for LC patients and their spouses. This study evaluates the effect of new medicines on productivity, early retirement and survival for LC patients and their spouses. Data from the period 1 January 2004–31 December 2018 were collected from complete Danish registers. LC cases diagnosed before approval of first targeted therapy (19 June 2006, Before patients) were compared with those who received at least one new cancer treatment, diagnosed after this date (After patients). Subgroup analyses based on cancer stage, and epidermal growth factor receptor (EGFR) or anaplastic lymphoma kinase (ALK) mutation were conducted. Linear regression and cox regression were used to estimate the outcomes including productivity, unemployment, early retirement, and mortality. Spouses of Before and After patients were compared on earnings, sick leave, early retirement, and healthcare utilisation. The study population comprised of 4,350 patient (2,175 After/2,175 Before). Patients who received new treatments had a significantly reduced risk of death (Hazard ratio = 0.76, Confidence interval: 0.71 − 0.82) and reduced risk of early retirement (Hazard ratio: 0.54, Confidence interval: 0.38 − 0.79). No significant differences in earnings, unemployment, or sick leave were found. Spouses of Before patients had a higher cost of healthcare services after diagnosis compared to spouses of After patients. For productivity, early retirement and sick leave, no significant differences were found between the spouse groups. Patients who received innovative new treatments had reduced risk of death and reduced risk of early retirement. Spouses of LC patients who received new treatments had lower healthcare costs in the years following diagnosis. All findings indicate that recipients of new treatments had reduced burden of illness.

description: We present two patients with hepatic lesions associated with congenital portosystemic shunts (CPSS), a rare vascular malformation, in order to emphasize the variable clinical presentation of this condition and different management strategies in each case. CPSS can give rise to several complications such as hepatic encephalopathy, portopulmonary hypertension and hepatic tumors. These hepatic lesions though most commonly benign in nature have an increased risk of malignant transformation. Therefore, we underline the necessity of considering CPSS in the differential diagnoses for all cases of space-occupying hepatic lesions in pediatric patients.

description: A Bayesian estimation of a GARCH model is performed for US Dollar/Japanese Yen exchange rate by the Metropolis-Hastings algorithm with a proposal density given by the adaptive construction scheme. In the adaptive construction scheme the proposal density is assumed to take a form of a multivariate Student's t-distribution and its parameters are evaluated by using the sampled data and updated adaptively during Markov Chain Monte Carlo simulations. We find that the autocorrelation times between the data sampled by the adaptive construction scheme are considerably reduced. We conclude that the adaptive construction scheme works efficiently for the Bayesian inference of the GARCH model.

Two New Tests of the Metallicity Sensitivity of the Cepheid Period-Luminosity Relation (The Leavitt Law)

Year: 2011
Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)

description: We undertake a new test of the metallicity sensitivity of the Leavitt Law for Classical Cepheids. We derive an empirical calibration of the apparent luminosities of Cepheids as measured from the optical through the mid-infrared (0.45-8.0um) as a function of spectroscopic [Fe/H] abundances of individual Cepheids in the Large Magellanic Cloud from Romaniello et al. (2008). The cumulative trend over the entire wavelength range shows a nearly monotonic behavior. The sense of the trend is consistent with differential line-blanketing in the optical, leading to stars of high metallicity being fainter in the optical. This is followed by a reversal in the trend at longer wavelengths, with the cross-over occurring near the K band at about 2.2um, consistent with a subsequent redistribution of energy resulting in a mild brightening of Cepheids (with increased metallicity) at mid-infrared wavelengths. This conclusion agrees with that of Romaniello et al. based on a differential comparison of the mean V- and K-band Leavitt Laws for the Galaxy, SMC and LMC, but is opposite in sign to most other empirical tests of the sensitivity of Cepheid distances to mean [O/H] HII region abundances. We also search for a correlation of Cepheid host-galaxy metallicity with deviations of the galaxy's Cepheid distance from that predicted from a pure Hubble flow. Based on Cepheid distances to 26 nearby galaxies in the local flow, only a very weak signal is detected giving Dmu_o = -0.17 (+/- 0.31) ([O/H] - 8.80) - 0.21 (+/-0.10). This is in agreement with previous determinations, but statistically inconclusive.

description: A recent Letter [Phys. Rev. Lett. 103, 156101 (2009)] reports the experimental observation of aggregation of colloidal particles dispersed in a liquid mixture of heavy water and 3-methylpyridine. The experimental data are interpreted in terms of a model which accounts solely for the competing effects of the interparticle electrostatic repulsion and of the attractive critical Casimir force. Here we show, however, that the reported aggregation actually occurs within ranges of values of the correlation length and of the Debye screening length ruled out by the proposed model and that a significant part of the experimental data presented in the Letter cannot be consistently interpreted in terms of such a model.

description: Infection with the human papillomavirus (HPV) causes precursor intraepithelial lesions in women which may lead to the development of cervical cancer. There are several HPV types which show a variable distribution pattern worldwide. Therefore, identifying the prevalence of cancer-associated HPV types is important for the prevention of cervical cancer. In the current study, 627 cervical samples from individual women were collected by primary care clinics in Greece. The majority of women (70.17%) presented abnormal cytology as indicated by their Pap Test smear. Samples were sent to our laboratories for the detection of HPV by DNA analysis, PCR and reverse hybridization using HPV genotype-specific probes. Then, the prevalence of 28 different genotypes was estimated. Approximately 70% of all samples were infected with at least one HPV type. The most prevalent high risk (HR) HPV types associated with the development of cervical cancer were HPV types 16, 31 and 51. Prevalence of HPV types, as well as appearance of them as a single or multiple infection were also studied in samples with normal and abnormal cytology. Our analysis showed that infected women with normal cytology in our study population tend to have single HPV infections. In contrast, those with abnormal cytological phenotype tend to have multiple infections of HR HPV types.

description: This article is focused on the dynamics of a rotating electrically conducting fluid in a turbulent state. As inside the Earth's core or in various industrial processes, a flow is altered by the presence of both background rotation and a large scale magnetic field. In this context, we present a set of 3D direct numerical simulations of incompressible decaying turbulence. We focus on parameters similar to the ones encountered in geophysical and astrophysical flows, so that the Rossby number is small, the interaction parameter is large, but the Elsasser number, defining the ratio between Coriolis and Lorentz forces, is about unity. These simulations allow to quantify the effect of rotation and thus inertial waves on the growth of magnetic fluctuations due to Alfvén waves. Rotation prevents the occurrence of equipartition between kinetic and magnetic energies, with a reduction of magnetic energy at decreasing Elsasser number Λ. It also causes a decrease of energy transfer mediated by cubic correlations. In terms of flow structure, a decrease of Λ corresponds to an increase in the misalignment of velocity and magnetic field.

description: Chromosomal Microarray Analysis (CMA) is currently considered to be the first-tier clinical test for neurodevelopmental disorders, such as Intellectual Disability (ID)/ Developmental Delay (DD) and Autism Spectrum Disease (ASD) due to its ability to detect Copy Number Variants (CNVs). CNVs are defined as segments of DNA which might either be deleted or duplicated and represent the most prevalent type of structural variation in the human genome. Recently, they have been found to be the causative agent for approximately 15-20% of previously undiagnosed cases of neuro developmental disorders. The unceasingly growing number of microdeletion and microduplication syndromes (MMSs), identified through CMA, has significantly altered the diagnostic approach to disorders such as ID and ASD.

description: Salivary gland tumors are assumed to be predominantly malignant in the Greenlandic Inuit population, but there is limited literature on the subject. We conducted a retrospective cohort study using national registers to describe the histological tumor types, location, incidence, and survival of benign and malignant salivary gland tumors. We analyzed data on all Greenlandic Inuit with an epithelial-derived salivary gland tumor from 1990 to 2019. We extracted data from the Central Personal Registry and crossmatched it with the Danish Pathology Data Bank. All specimens were reviewed by a specialized pathologist. We noted patient and histological characteristics, calculated crude and age-adjusted incidence rates, overall survival, and excess mortality. Our study found that 76% of salivary gland tumors in the Greenlandic Inuit population were benign, with pleomorphic adenoma being the most common. Malignant tumors accounted for 24% of cases, with lymphoepithelial carcinoma being the most common type. The most common place of origin for malignant tumors was the parotid gland (71%) and the submandibular gland (15%). The median age of onset for malignant tumors was 47 years. Age-adjusted incidence rates of malignant tumors for men and women were 3.00 and 4.12 per 100,000 person-years, respectively. Our findings suggest that the proportion of malignant salivary gland tumors in the Greenlandic Inuit population is similar to other nonendemic populations. Our incidence rates are higher than previously reported, likely due to differences in methodology and definitions of the Inuit population. This study provides valuable insights into the epidemiology of salivary gland tumors in the Greenlandic Inuit population and may have implications for other Inuit populations as well.

description: Outbreaks of various forms of diarrhoea, particularly cholera and typhoid, are a frequent occurrence in low income countries. Poor water sanitation and hygiene practices are frequently implicated for all diarrhoeal out breaks in the low income countries. The present study assessed (i) the probiotic potential of selected strains of lactic acid bacteria in terms of their inhibition activities against Escherichia coli O157:H7 and Salmonella typhi, and the removal of heavy metals in wastewater. The selected lactic acid bacteria had probiotic properties, namely resistance to low pH (pH2 and 3), tolerance to bile salts and sodium chloride, and significant antimicrobial activities against strains of E. coli O157:H7 and S. typhi (p 0.001). Strains of lactic acid bacteria were shown to modulate the concentration of aqueous Cu, Mn, NH4 + and Zn with a significant net decrease between Day 7 or 10 (p ≤ 0.05). The selected lactic acid bacteria were also shown to deploy biofilms on surfaces of sand particles, which are thought to constitute a mechanism by the lactic acid bacteria to hold and kill E. coli and S. typhi in wastewater. The lactic acid bacteria have exhibited great potential for use in the removal of diarrhoeagenic bacteria and heavy metals from wastewater.

description: We present an automated system for detecting, tracking, and cataloging emerging active regions throughout their evolution and decay using SOHO Michelson Doppler Interferometer (MDI) magnetograms. The SolarMonitor Active Region Tracking (SMART) algorithm relies on consecutive image differencing to remove both quiet-Sun and transient magnetic features, and region-growing techniques to group flux concentrations into classifiable features. We determine magnetic properties such as region size, total flux, flux imbalance, flux emergence rate, Schrijver's R-value, R* (a modified version of R), and Falconer's measurement of non-potentiality. A persistence algorithm is used to associate developed active regions with emerging flux regions in previous measurements, and to track regions beyond the limb through multiple solar rotations. We find that the total number and area of magnetic regions on disk vary with the sunspot cycle. While sunspot numbers are a proxy to the solar magnetic field, SMART offers a direct diagnostic of the surface magnetic field and its variation over timescale of hours to years. SMART will form the basis of the active region extraction and tracking algorithm for the Heliophysics Integrated Observatory (HELIO).
Offering surgical castration to detainee sex-offenders: The ‘unkindest cut’

Subjects: Sex-offender; surgical castration; autonomy, moral agent; decision-making capacity; coercive offer.

description: The still available in some jurisdictions offer of surgical castration to sex-offenders raises ethical concerns. The narrow castration law in Texas has found supporters since it does not mandate castration, instead reserving it for repeat offenders who seek the treatment. McMillan’s proposal views imprisoned sex-offender as competent agent to give valid and autonomous informed consent when certain requirements are met. Another major pro-castration argument asserts that compromising one’s autonomy for enhancing or restoring it in the long run can justify the non-consensual surgical castration. This paper challenges these arguments focusing mostly on sex-offender’s agency. The major point raised by this paper is that a sex-offender who is locked in prison, in all likelihood, is in an unhealthy (or quasi unhealthy) off balance state (from a phenomenological standpoint) and possibly he has limited human bandwidth and low self-esteem. Such a sex-offender could be unduly induced or nudged into consent to offered castration and this is a decisive moral problem. Besides, surgical castration is an intervention that leads to a situation which the person who request it has never experienced before. Therefore, the detainee sex-offender’s competence to give valid and autonomous informed consent to surgical castration is questionable. Besides, justice-related concerns are raised in case of offering surgical castration to detainee sex-offenders. Moreover, in author’s opinion the state might hardly offer surgical castration without pro-castration intention. Furthermore, this paper regards as questionable the role of psychiatrist as a guarantor of sex-offender’s agency and the effectiveness of surgical castration as medical treatment.

Experimental investigation of the effect of broken ore properties on secondary fragmentation during block caving
Creators: name: Dorador, Leonardo
Publisher: name: University of British Columbia
Year: 2016

description: Block cave mining is experiencing a global growth in importance as new large, lower grade and deeper ore bodies favouring underground mass mining methods are developed. With block caving, the rock mass fragmentation process is decisive in the design and success of the operation. The last stage of this fragmentation process known as secondary fragmentation, plays a major role in the design and success of a caving operation. Despite this, it is the least understood fragmentation stage due in part to the complex mechanisms and the numerous variables involved in this phenomenon. The broken ore density (BOD) and the inter-block friction angle (ϕ') are comprehensively investigated here. A conceptual framework describing the BOD distribution and a procedure to evaluate this parameter under both an isolated movement zone and interactive flow are proposed, and an approach to evaluate ϕ' under different broken ore properties and draw column conditions is developed to be applied to early stage feasibility studies and design. A comprehensive laboratory testing program was carried out using concrete cuboids, controlling their size, shape and compressive strength. These are used as a proxy for broken ore fragments. These results were used to develop empirical design charts for assessing secondary fragmentation and hang-ups potential. Several factors influencing the secondary fragmentation for feasibility and advanced engineering assessments have been investigated including: air gap thickness, BOD, segregation of large blocks due to draw column surface topology, broken ore strength heterogeneity, block strength damage and crushing under high confining stresses, water within draw columns, and cushioning by fines. This new knowledge will contribute to more accurate secondary fragmentation predictions at the drawpoints. Finally, a new empirical approach to predict secondary fragmentation and drawpoint block size distribution (BSD) directed at early-stage conceptual and feasibility engineering design studies is developed. This methodology, built with relevant data from related fields and supplemented by generated data, was tested against field data from the El Teniente mine, Chile, confirming satisfactory predictions for stronger rocks and mixtures of strong and weak broken ore materials. The results were not as reliable for predicting drawpoint BSD for weak rocks.

description: Given the rapid advances in assisted reproductive technology, the need for providing a more nuanced insight into the understanding of the concept biological parenthood becomes all the more evident. With the aim of providing nuance and balance to the extant literature regarding the concept of biological parenthood, this paper attempts to show that a) the desire for biological parenthood bears a deeper meaning than a prejudice-based legitimate will, and b) this assumption does not necessarily reflect a sharp distinction between biological and social parenthood, which may profoundly affect negatively intimate bonds between family members. The paper is articulated in three steps. In a first step, this paper attempts to identify a number of arguments that might count as good evidence to emphasize the role of biological relatedness between parent and offspring in the context of modern techno-science, social reality and theoretical thinking. In a second step, it defends the assumption that people are strongly motivated to desire genetic relatedness with as high as possible relatedness coefficient. Further, in a third step, this study moves forward on a novel (individual) account of parenthood that is a biological/social hybrid in the case where (social) parenthood starts during early neonatal period. This interim account of parenthood (between biological and social parenthood) comes from the heart and the parent-newborn attachment. Social parenthood would be considered not purely social when starting at the very beginning of child’s life. This borderline account of parenthood might smooth out the categorical distinction between biological and social parenthood.

description: Excerpts from the report: Handling and disposing of solid waste generated in wholesale food distribution centers can be a significant problem. Recent and pending antipollution legislation in some areas of the country is limiting the choice of solid waste management systems and forcing some centers to upgrade present waste management methods. An indepth engineering study and evaluation of solid waste sources and types, waste generation rates, and methods of waste handling and disposal at selected food distribution centers were conducted. The study included onsite surveys at six centers, evaluation of waste management systems used at each center, consideration of alternative waste management methods, and recommendations for applicable alternative waste management methods. This report sets forth recommendations that resulted from the methodology and findings of the study. The report is intended for use by center management in selecting a cost-effective solid waste management system suitable for their particular center

description: Non-linear simulation results for a 220-GHz rectangular dielectric-loaded traveling wave amplifier are presented. Simulations are used to check a linear theory that is developed by phenomenological introduction of an effective dielectric parameter for electron beam channel, and it is found that the RF power gains from Pierce three-wave theory and particle simulations are in reasonable agreement. It is shown that the RF power gain during initial beam-wave interaction is positive; the falling on the initial RF power profile, which has been thought to be the RF power transferred to the beam for bunching buildup (negative gain effect), is probably resulting from numerical errors. Beam-wave interaction mechanism is analyzed by examining the evolution of beam bunching centers. Influences of various parameters on amplifier performance are examined, and transverse space-charge effect is analyzed. A symmetric excitation scheme for RF couplers is proposed, and RF field jumps on the common intersection line of vacuum, dielectric, and metal wall, which is found in RF simulations, are explained theoretically.

description: We investigate the ultraviolet and optical properties and environment of low redshift galaxies detected in the Herschel Astrophysical Terahertz Large Area Survey (H-ATLAS) science demonstration data. We use the Sloan Digital Sky Survey seventh release and the Galaxy And Mass Assembly database to select galaxies with r_Petro < 19.0 mag in the redshift range 0.02 < z < 0.2 and look for their submillimeter counterparts in H-ATLAS. Our results show that at low redshift, H-ATLAS detects mainly blue/star-forming galaxies with a minor contribution from red systems which are highly obscured by dust. In addition we find that the colour of a galaxy rather than the local density of its environment determines whether it is detectable by H-ATLAS. The average dust temperature of galaxies that are simultaneously detected by both PACS and SPIRE is 25K \pm 4K, independent of environment. This analysis provides a glimpse of the potential of the H-ATLAS data to investigate the submillimeter properties of galaxies in the local universe.

Frequency-dependent ratchet effect in superconducting films with a tilted washboard pinning potential

description: The influence of an ac current of arbitrary amplitude and frequency on the mixed-state dc-voltage-ac-drive ratchet response of a superconducting film with a dc current-tilted uniaxial cosine pinning potential at finite temperature is theoretically investigated. The results are obtained in the single-vortex approximation, i.e., for non-interacting vortices, within the frame of an exact solution of the appropriate Langevin equation in terms of a matrix continued fraction. Formulas for the dc voltage ratchet response and absorbed power in ac response are discussed as functions of ac current amplitude and frequency as well as dc current induced tilt in a wide range of corresponding dimensionless parameters. Special attention is paid to the physical interpretation of the obtained results in adiabatic and high-frequency ratchet responses taking into account both running and localized states of the (ac+dc)-driven vortex motion in a washboard pinning potential. Our theoretical results are discussed in comparison with recent experimental work on the high-frequency ratchet response in nanostructured superconducting films [B. B. Jin et al., Phys. Rev. B 81 (2010) 174505].

The foetal right to life

Subjects: law, right to life, foetus

description: The case of Vo v France brought forward the controversial issue if the foetus is entitled to “everyone’s” right to life as described in Article 2 of the European Convention on Human Rights (ECHR). This issue consequently raises the question of when life begins, the legal status of the foetus and its connection with its mother’s rights. The European Court of Human Rights examined this issue many times but has never adopted a clear position on the matter, it rather avoids answering the question and is emphasizing more on allowing the Member States to decide according to their culture, religion, social and economic factors on this issue.

The legal aspect of informed consent in surgery

Publisher: name: Aristotle Biomedical Journal

Subjects: law, informed consent, surgery, autonomy.

description: The issue of informed consent has become of main importance as the doctor/ patient relationship transformed from paternalistic to cooperative. The conservatively uneven sociological relationship between the doctor and his patient is now considered obsolete as it has become a joint effort combining both parties. The fact that there is no other contract in Civil Law that has as a subject the life, health and well-being of a person, gives the contract for medical treatment a humane character and not the typicality of a contract of Civil Law justifying the emphasis on informed consent. Both the doctor and the patient linked together by mutual trust must participate, cooperate and decide the course of the treatment. In this context, informed consent is crucial to reassure patient’s autonomy and self-conscious decision making for any treatment and more importantly before deciding to undergo surgery. When it comes to informed in surgery the same rules as in general apply with the specialization of certain points because of the severity of this situation.

description: Background In Denmark, the Cancer Patient Pathway for Non-Specific Signs and Symptoms (NSSC-CPP) has been implemented with variations: in some areas, general practitioners (GPs) do the initial diagnostic work-up (GP paradigm); in other areas, patients are referred directly to the hospital (hospital paradigm). There is no evidence to suggest the most beneficial organisation. Therefore, this study aims to compare the occurrence of colon cancer and the risk of non-localised cancer stage between the GP and hospital paradigms. Material and Methods In this registry-based case-control study, we applied multivariable binary logistic regression models to estimate the odds ratios (OR) of colon cancer and non-localised stage associated with the GP paradigm and hospital paradigm. All cases and controls were assigned to a paradigm based on their diagnostic activity (CT scan or CPP) six months before the index date. As not all CT scans in the control group were part of the cancer work-up as a sensitivity analysis, we investigated the impact of varying the fraction of these, which were randomly removed using a bootstrap approach for inference. Results The GP paradigm was more likely to result in a cancer diagnosis than the hospital paradigm; ORs ranged from 1.91–3.15 considering different fractions of CT scans as part of cancer work-up. No difference was found in the cancer stage between the two paradigms; ORs ranged from 1.08–1.10 and were not statistically significant. Conclusion Patients in the GP paradigm were diagnosed with colon cancer more often, but we cannot conclude that the distribution of respectively localised or non-localised extent of disease is different from that of patients in the hospital paradigm.
