The analytical one-loop contributions to Higgs boson mass in the Supersymmetric Standard Model with vector-like particles
Authors: Li Tianjun , Wang Wenyu , Wang Xiao-Chuan , Xiong Zhao-Hua 
Published: November 2017

In this paper, we extend the Minimal Supersymmetric Standard Model (MSSM) with additional vector-like particles (VLPs) and compared the differences of mass spectrum and Feynman rules between the MSSM and MSSMV. We analytically calculate the one loop contributions to the Higgs boson mass from the fermions and sfermions in the on shell renormalization scheme. After discussing and numerically analyzing cases without bilinear terms and a case with a (partial) decoupling limit, we find: (i) the corrections depend on the mass splittings between quarks and squarks and between vector-like fermions and their sfermions; (ii) there exists the (partial) decoupling limit, where the VLPs decouple from the electroweak (EW) energy scale, even when one of the VLPs is light around the EW scale. The reason is that the contributions to Higgs mass can be suppressed by the (or partial) decoupling effects, which can make the EW phenomenology different from the MSSM. Moreover, we present some numerical analysis to understand these unique features.

Let [Formula: see text] be a connected graph and [Formula: see text] be the distance between the vertices [Formula: see text] and [Formula: see text] in [Formula: see text]. The diameter of [Formula: see text] is defined as [Formula: see text] and is denoted by [Formula: see text]. A subset of vertices [Formula: see text] is called a resolving set for [Formula: see text] if for every two distinct vertices [Formula: see text], there is a vertex [Formula: see text], [Formula: see text], such that [Formula: see text]. A resolving set containing the minimum number of vertices is called a metric basis for [Formula: see text] and the number of vertices in a metric basis is its metric dimension, denoted by [Formula: see text]. Metric dimension is a generalization of affine dimension to arbitrary metric spaces (provided a resolving set exists). Let [Formula: see text] be a family of connected graphs [Formula: see text] depending on [Formula: see text] as follows: the order [Formula: see text] and [Formula: see text]. If there exists a constant [Formula: see text] such that [Formula: see text] for every [Formula: see text] then we shall say that [Formula: see text] has bounded metric dimension, otherwise [Formula: see text] has unbounded metric dimension. If all graphs in [Formula: see text] have the same metric dimension, then [Formula: see text] is called a family of graphs with constant metric dimension. In this paper, we study the metric properties of an infinite class of circulant graphs with three generators denoted by [Formula: see text] for any positive integer [Formula: see text] and when [Formula: see text]. We compute the diameter and determine the exact value of the metric dimension of these circulant graphs.

Published: November 2017

<b><i>Background/Aims:</i></b> Acute kidney injury (AKI) has been reported as a recognized condition among the elderly population; however, its clinical epidemiology is still poorly evaluated. We propose to evaluate the epidemiological profile of AKI in hospitalized elderly patients and the variables associated with renal replacement therapy (RRT) dependency at discharge after an episode of AKI. <b><i>Methods:</i></b> This prospective observational study enrolled 286 elderly patients (aged ≥60 years), who had a diagnosis of AKI and were admitted to a tertiary care hospital. Clinical data were analyzed, which included RRT indication, referral time to nephrologist support, standby period in the emergency care units (ECU) before a transfer to an intensive care unit, staff criteria used to indicate palliative care, and the incidence of patients who stayed on chronic dialysis for at least 6 months after discharge. <b><i>Results:</i></b> The overall hospital mortality was 56.3%. Acute Kidney Injury Network (AKIN) 3 at the time of admission was significantly higher in patients who underwent RRT. Intrinsic AKI (<i>p</i> &#x3c; 0.001), AKIN 3 (<i>p</i> &#x3c; 0.001), RRT (<i>p</i> &#x3c; 0.001), and increased length of stay in ECUs (<i>p</i> = 0.01) all had a significantly higher prevalence among non-survivors. On multivariate analysis, however, only renal aetiology (intrinsic AKI) was independently associated with mortality (OR 2.88; 95% CI [1.29–6.13]). Approximately 85% of the discharged patients (<i>n</i> = 125) were dialysis free and 36.4% of them who had a previous diagnosis of chronic kidney disease (CKD) upon admission had a worse renal function. Age, AKIN 3, RRT, prior history of CKD, diabetes mellitus, and the number of hemodialysis sessions showed to have an impact on dialysis dependence. Furthermore, 24 of 161 patients who had a dialysis indication were placed on palliative care. <b><i>Conclusions:</i></b> The severity of AKI and the need for RRT were risk factors for mortality and dependence on dialysis. Antecedents of CKD seem to be associated with a poor renal outcome following an AKI episode. Starting RRT had an impact on the clinical decision to enroll these patients into palliative care.

Published: November 2017

<b><i>Background and Aims:</i></b> We aimed to introduce a parameter of anterior borderzone angle (ABZA) to quantitatively evaluate the ACA-MCA leptomeningeal collaterals for middle cerebral artery stenosis (MCAS). <b><i>Methods:</i></b> Two hundred seventy-five patients with 50–100% MCAS and 100 controls were included. The 95% reference range of ABZA was obtained from the controls. ABZA<sub>trans</sub> was defined as “ABZA/the 95% upper limit.” Relationships between ABZA and MCAS, ­ABZA<sub>trans</sub> and the TICI grade, the American Society of Interventional and Therapeutic Neuroradiology/Society of Interventional Radiology (ASITN/SIR) collateral grade were analyzed. An ABZA grade model for the ACA leptomeningeal collaterals was tentatively developed. <b><i>Results:</i></b> The 95% reference range of ABZA was 0.0º–23.0º. ABZA was significantly associated with MCAS by a function of the fourth power (R<sup>2</sup> = 0.723, <i>p &#x3c;</i> 0.001), and could predict hemodynamic MCAS (≥70%) with an AUC of 0.928 (95% CI 0.903–0.953). ABZA<sub>trans</sub> was negatively correlated with the TICI grade (rho<i> =</i> –0.752, <i>p &#x3c;</i> 0.001) and positively with the ASITN/SIR grade (rho<i> =</i> 0.921, <i>p &#x3c;</i> 0.001). The ABZA grade was created by rounding ­ABZA<sub>trans</sub> to a nearest integer, and was closely associated with the ASITN/SIR grade (rho = 0.894, <i>p &#x3c;</i> 0.001). <b><i>Conclusions:</i></b> ABZA can be used as a hemodynamic parameter to quantitatively evaluate ACA leptomeningeal collaterals.
The Emotional Experience behind Sexually Offending in Context
Authors: Leclerc Benoit , Lindegaard Marie Rosenkrantz 
Published: November 2017

Objectives: The current study focused on the role of affective states in adult sexual offending. We look at the prevalence of a range of affective states throughout sexual crime events. We break down the crime event into three stages—immediately before, during, and after the offense. We examine transitions of affective states—stage by stage—but also across victims. Finally, we investigate the impact of situational factors on affective states. Method: The sample consisted of a total of 553 adult males who had been convicted of a sexual offense. Self-report data on sexual crime events were collected from these offenders. Apart from descriptive and bivariate analysis, “affective state-switching patterns” are investigated through transition matrices. Results: Findings show large variations in affective states before, during, and after the offense but show little variation across victims. Alcohol usage and offender–victim relationship were related to affective states of offenders. Conclusions: We conclude that the found association between affective states and decision-making of sexual offenders calls for more research on within crime event variations especially, and future research should focus on causal mechanisms related to affective states.
Ocular Air-Gun Injury: 19 Cases
Authors: Shuttleworth G N , Galloway P H 
Published: November 2017

There have been many calls for preventive action against injuries caused by air-guns. Eye injuries are particularly serious, and we conducted a retrospective study to review their characteristics. Ophthalmic consultants in the south-west region of England and South Wales were asked to recollect any injuries that had resulted from air weapons. Information was recorded on the nature and circumstances of the injury, subsequent management, and long-term effects. 19 cases of ocular injury were identified, sustained at mean age 19.7 years, all in the past decade. 15 of the victims were male. At least 12 shootings were accidental but 2 were deliberate. The injury was self-inflicted in 5 cases, and in 6 the assailant was known to the victim. 9 sustained ruptured globes and 8 had severe contusions. Ultimately 4 individuals required enucleation and 2 evisceration. At last review, visual acuity was no perception of light in 10 (53%) and ‘counting fingers’ or worse in 16. Victims spent an average of nearly 10 days as an inpatient. The characteristics of the incidents that lead to ocular air-weapon injuries are unchanged. Reform of the firearms laws is probably the best way to prevention.
Brittle Diabetes in the Elderly
Authors: Benbow Susan J , Walsh Angela , Gill Geoffrey V 
Published: November 2017

Severely unstable, or brittle, diabetes can be disruptive to patients, carers and diabetes care teams. The peak age-group for brittle diabetes is 15–30, but there are reports of its occurrence in much older patients. To explore the characteristics and cause of brittle instability perceived by diabetologists in elderly patients we circulated a questionnaire to all UK hospital diabetic clinics for adults. 130 (56%) of 231 replied. Reports were obtained on 55 patients fulfilling our criteria for ‘elderly brittle diabetes’–namely, age ≤ 60 years, on insulin treatment, and experiencing life-disrupting glycaemic instability of any kind associated with frequent or long admissions to hospital. Further information was obtained by a research nurse who visited the relevant clinics. The mean age of patients was 74 years (range 60–89) and 71 % were female. The brittleness was classed as mixed glycaemic instability in 22 (44%), recurrent ketoacidosis in 16 (29%) and recurrent hypoglycaemia in 15 (27%). In 2 cases there was insufficient information for classification. The diabetes care team judged the brittleness to have multiple origins in two-thirds of the cases: problems with memory or behaviour were rare, and in only 4 cases was deliberate manipulation of therapy considered a possibility. 84% of the patients were living independently. In younger patients the principal manifestation of brittle diabetes is recurrent ketoacidosis. The present survey, though possibly subject to ascertainment bias, indicates that the patterns of instability and their causation may be different in elderly patients. With the growing use of insulin in the elderly, brittle diabetes is likely to be encountered increasingly often in this age-group.
‘Referral into a Void': Opinions of General Practitioners and Others on Single Point of Access to Mental Health Care
Authors: Raine Rosalind , Carter Simon , Sensky Tom , Black Nick 
Published: November 2017

In the past, British general practitioners (GPs) have referred patients to individual consultants. There is now a trend towards generic referral, whereby the specialist team is consulted via a single point of access. We examined the impact of this innovation on the relationship between GPs and specialists in mental health care. Sixteen groups of randomly selected GPs and mental health professionals (MHPs) in England discussed clinical scenarios involving the use of mental health interventions for patients with functional somatic symptoms. The meetings were audiotaped, transcribed and analysed to the point at which no major new themes were emerging. The final analysis was confined to a purposive sample of six of the sixteen groups, comprising 54 GPs and 15 MHPs. Although the rationale for the single point of access was clear to both GPs and MHPs, the approach erected boundaries because it impeded the establishment of professional relationships and transfer of knowledge. GPs thought the system reduced their capacity to be accountable to their patients and limited the potential for their own professional development. MHPs did not seem to be aware of GPs’ concerns. Effective interprofessional management of individual patients depends upon confidence in colleagues’ skills and good communication. Factors that hamper these must be addressed in the development of this system of referral.
Ethics in nursing: A systematic review of the framework of evidence perspective
Authors: Yıldız Erman 
Published: November 2017

Aim: To determine the current state of knowledge on nursing and ethics and to assess the knowledge and experience based on the evidence in this regard. Background: Although ethics is at the center of the nursing profession and the ethical issues affecting nurses are given much importance, few studies have focused on professional ethics in nursing. In this respect, ethics has become a concept that contains controversial and ambiguous situations. Design: The Preferred Reporting Items for Systematic Reviews and Meta-analyses guide, a basic search algorithm, was taken. Data sources: Cochrane, PubMed, CINAHL Complete, PsycINFO, and ULAKBIM from 2012 to 2016. Review methods: Following a systematic search strategy, all papers were assessed in relation to inclusion criteria and type of study. When sufficient information was not available in the title and summary of the works, the necessary data were evaluated in full texts. Results: This review was completed with 27 articles meeting the research criteria. The evaluation identified six themes: (1) ethics and nursing, (2) ethical difficulties/ethical dilemmas and nursing, (3) ethical competence and nursing, (4) professional ethics and nursing, (5) ethics, education, and nursing, and (6) ethics in health research. Conclusion: As a result of the review, a synthesis of high evidence-level research relating to nursing ethics was obtained. The emphasis was on the importance of further research and education so that the ethical aspects of nursing can be better understood throughout the studies. Nursing researchers’ level of evidence on ethics and their orientation to high research design will shed light on uncertain and controversial aspects of the subject. Ethical consideration: Since this was a systematic review, no ethical approval was required. There is no conflict of interest in this literature review.

Objectives: Even if patients with terminal cancer hope to spend the rest of their lives at home, they are often unable to leave the hospital early due to their family caregivers’ anxiety. This study aimed to investigate in Japan the discrepancies between the supports needed by and actually provided by palliative care unit nurses (PCUNs) to the family caregivers for discharge of patients with terminal cancer. Methods: In this cross-sectional study, self-administered questionnaires including 6-point Likert-type scales assessing the reasons for difficulties in transition to home-based care were distributed to 1227 PCUNs. Using paired t tests, the differences between the scores on perceived importance and actual supports to family caregivers were examined. The supports actually provided were classified by factor analysis. The relationships between the PCUNs’ characteristics and mean scores on the supports in each category were examined using multiple regression analysis. Results: A total of 1023 (83.4%) completed questionnaires were returned. Scores on the actually provided supports for discharge to family caregivers were consistently and significantly lower than the corresponding scores on perceived importance for all 57 items ( P < .001). Factor analysis revealed that the supports actually provided to the family caregivers had a 4-factor structure. Multiple regression analyses revealed that gaining experience in palliative care, receiving necessary training, cooperating with palliative care staff, and cooperating with local service providers were significantly associated with higher levels of actual supply of supports to family caregivers. Conclusion: Our findings suggest that PCUNs need to be encouraged to provide further support to family caregivers for the discharge of patients with terminal cancer.

Published: November 2017

Introduction Thoracic aortic injury is a leading cause of death after blunt trauma, but the effect of trauma system organization on outcomes is undefined. This was an analysis of thoracic aortic injury in a state with a comprehensive trauma system. Methods This was a retrospective study of thoracic aortic injury in Maryland between 2009 and 2014 using a statewide inpatient admission database. Presence of thoracic aortic injury and open or endovascular aortic interventions were identified by International Classification of Diseases version 9 codes. Patients were compared by admitting hospital status, categorized as Level I or non-Level I trauma centers. Outcomes were overall inpatient mortality and death after aortic repair. Results Of 774,211 injured patients, 168 (0.02%) had thoracic aortic injury. Patients with thoracic aortic injury were younger, more often male, and were more severely injured than patients without thoracic aortic injury. The majority of patients (136, 81%) were admitted to Level I trauma centers; Level I and non-Level I patients had similar characteristics. Most patients (110, 65%) were managed non-operatively, but patients admitted to Level I facilities were more likely to undergo aortic repair. Overall and post-operative mortality rates were lower at Level I hospitals (22% versus 31% and 6% versus 17%, respectively), but these differences did not reach statistical significance. Conclusion This novel analysis indicates thoracic aortic injury management in Maryland is highly concentrated at Level I trauma centers, which was associated with mortality below previously reported national rates. Although limited by small sample size, these findings suggest a benefit to regionalized care for patients with thoracic aortic injury and support transfer to high-volume facilities for definitive management.

Published: November 2017

Aims: To assess the effects of sodium-glucose co-transporter type 2 inhibitors on central blood pressure, an important determinant of cardiovascular events. Methods: Canagliflozin, Empagliflozin or Luseogliflozin was given for 102 type 2 diabetic patients with hypertension and nephropathy. Central blood pressure was evaluated by radial tonometry. Clinical parameters were followed for 6 months. Results: Three differing sodium-glucose co-transporter type 2 inhibitors similarly reduced brachial and central blood pressures, casual blood sugar, haemoglobin A1c, estimated glomerular filtration rate and albuminuria without significant changes in pulse rate and lipid profiles. Central systolic blood pressure was associated with the decreases in albuminuria by sodium-glucose co-transporter type 2 inhibitors. Conclusion: Comparable influences of various sodium-glucose co-transporter type 2 inhibitors on central blood pressure suggest class effects.

Published: November 2017

Case summary An 8-year-old female spayed Siamese indoor cat presented with a 3 week history of inspiratory dyspnoea, stridor and open-mouth breathing after exercise. Laryngoscopy, tracheoscopy, bronchoscopy and retroflexed nasopharyngoscopy were performed, and identified a multilobulated intraluminal mass within the trachea. Brush cytology was performed on the mass but was inconclusive in providing a definitive diagnosis. A CT scan of the neck failed to identify an obvious intraluminal mass and was negative to contrast uptake. Surgery was performed and seven rings of the trachea were removed to enable the complete excision of the mass. Histopathology of the excised mass was consistent with B cell lymphoma. After surgery, chemotherapy treatment was started. At the time of writing, 20 months since diagnosis, the cat remained clinically well, with no clinical signs or recurrence of macroscopic disease on endoscopic evaluation. Relevance and novel information Upper airway endoscopy was considered to be an essential diagnostic tool in this case presenting with signs of upper respiratory dyspnoea. Moreover, combined surgery and chemotherapy were considered effective treatments and positively affected the long-term prognosis of this patient.

We studied the prevalence, burden and potential risk factors for chronic bronchitis symptoms in the Burden of Obstructive Lung Disease study.Representative population-based samples of adults aged ≥40 years were selected in participating sites. Participants completed questionnaires and spirometry. Chronic bronchitis symptoms were defined as chronic cough and phlegm on most days for ≥3 months each year for ≥2 years.Data from 24 855 subjects from 33 sites in 29 countries were analysed. There were significant differences in the prevalence of self-reported symptoms meeting our definition of chronic bronchitis across sites, from 10.8% in Lexington (KY, USA), to 0% in Ile-Ife (Nigeria) and Blantyre (Malawi). Older age, less education, current smoking, occupational exposure to fumes, self-reported diagnosis of asthma or lung cancer and family history of chronic lung disease were all associated with increased risk of chronic bronchitis. Chronic bronchitis symptoms were associated with worse lung function, more dyspnoea, increased risk of respiratory exacerbations and reduced quality of life, independent of the presence of other lung diseases.The prevalence of chronic bronchitis symptoms varied widely across the studied sites. Chronic bronchitis symptoms were associated with significant burden both in individuals with chronic airflow obstruction and those with normal lung function.
