Performance evaluation of hop-based range-free localization methods in wireless sensor networks

Knowledge of nodes' locations is an important requirement for many applications in Wireless Sensor Networks. In the hop-based range-free localization methods, anchors broadcast the localization messages including a hop count value to the entire network. Each node receives this message and calculates its own distance with anchor in hops and then approximates its own location. In this paper, we review range-free localization methods and evaluate the performance of two methods: "DV-hop" and "amorphous" by simulation. We consider some parameters like localization accuracy, energy consumption, and network overhead. Recent papers that evaluate localization methods mostly concentrated on localization accuracy. But we have considered a group of evaluation parameters, energy consuming, and network overhead in addition to the location accuracy.
Monitoring prescribing: GPs' use of Prescribing Analysis and Cost (PACT) data

Prescribing Analysis and Cost (PACT) data are sent to all GPs to assist them in monitoring their prescribing. Although the quarterly Standard Reports contain a great deal of information it is not known how GPs make use of it. This paper reports on two linked studies which explore GPs' views on PACT Standard Reports and PACT catalogue data. In the first study, interviews were carried out with 21 GPs in 16 practices selected according to criteria related to their prescribing budget. The interview schedule included questions on how the Standard Reports were used and the amount and ease of understanding of the information provided, and on use of PACT Catalogue data. The second study was a questionnaire survey of the 1047 practices in the West Midlands region in which GPs were asked how they used PACT data. Analysis of the interviews showed that GPs' views on the Standard Report varied widely although most found it helpful. Many GPs used the data in a limited way and only used a small part of them. Single-handed GPs and small practices were least likely to make use of PACT data and few practices analysed the data in any depth. Most respondents said that comparing their costs with health authority and national averages was useful for considering where to make changes in their prescribing. GPs indicated they would like the report to include some interpretation of the data with suggestions for changes which could be made. The regional survey confirmed that PACT Standard Reports are only used in a limited way and how they are used varies with practice size. We conclude that PACT Standard Reports were rarely used to analyse prescribing in any depth and GPs need more support in making better use of the data.
Late-onset Hemochromatosis: Co-inheritance of β-thalassemia and Hereditary Hemochromatosis in a Chinese Family: A Case Report and Epidemiological Analysis of Diverse Populations

Hereditary hemochromatosis and β-thalassemia can both result in the inappropriately low production of the hormone hepcidin, which leads to an increase in intestinal absorption and excessive iron deposition in the parenchymal cells. To the best of our knowledge, there have been no reports on the coexistence of the two disorders in China. We herein report a case in a Chinese who presented with late-onset hepatic cirrhosis with hereditary hemochromatosis and β-thalassemia. We analyzed the pedigree of the two disorders and the iron status in his family members. Our case supports that a heterozygous H63D mutation can interact with β-thalassemia, leading to late-onset hemochromatosis.
Using play therarpy in paediatric palliative care: listening to the story and caring for the body

To be truly comprehensive, palliative care for children must address more than pain control and symptom management. Holistic care also encompasses attention to the child’s relationships, hopes, fears and wishes. Parents and caregivers of dying children are generally the primary decision-makers in the child’s care and can find the transition from active, to palliative care, particularly difficult. Nurses who understand the parents’ perspective can better support them. Children reveal their hopes and fears through play. By being attuned to symbols and themes in play, nurses can better interpret the dying child’s journey. Nurses can facilitate communication and connection between parents and child and thereby promote healing during the dying process.
Atraumatic Splenic Rupture Due to Ectopic Extramedullary Hematopoiesis after Autologous Stem Cell Transplantation in a Patient with AL Amyloidosis

A 50-year-old man was diagnosed with multiple myeloma complicating AL amyloidosis. Splenic rupture was complicated during autologous stem cell transplantation (auto-SCT). Granulocyte colony-stimulating factor (G-CSF) was not administered. A pathological examination of the spleen revealed that CD34-positive cells were concentrated in the ruptured part of the splenic capsule. Hematopoietic cells were engrafted in the small gap between the capsule and amyloid protein deposition area of the spleen, which might have caused the splenic rupture in the absence of G-CSF administration. Special attention is thus required for amyloidosis patients undergoing auto-SCT, even when G-CSF is not administered.
Produtos de pesca e contaminantes químicos na água da Represa Billings, São Paulo (Brasil)

Atraves da analise dos surfactantes determinados pelo metodo colorimetrico com azul de metileno, e dos metais pesados determinados por espectrofotometria de absorcao atomica, como o cadmio, chumbo, cobre, cromo, mercurio e zinco, foi caracterizada a poluicao na Represa Billings, SP (Brasil), enfatizando a qualidade sanitaria da agua e a contaminacao dos peixes. Com base nos dados coligidos, e mostrado o perigo potencial que representa o consumo do pescado proveniente da Billings, se bem que a pesca comercial esteja hoje praticamente restrita as cabeceiras dos bracos dos rios Capivari e Pequeno, na juncao proxima a Ribeirao Pires e nos bracos dos rios Curucutu e Taquacetuba. Os dados da CEAGESP - Companhia de Entreposto de Armazens Gerais do Estado de Sao Paulo - indicam que, no ano de 1980, apenas 64 toneladas de peixe provieram de Sao Bernardo do Campo.
PREVALENCE OF BK VIRUS IN RENAL ALLOGRAFT RECIPIENTS PRE AND POST TRANSPLANTATION IN IRAN

BK virus, a member of polyomaviridae, infects humans asymptomatically in their early infancy and remains latent in the kidney and urinary tract cells. Reactivation of BK virus in renal-transplanted patients occurs frequently and sometimes leads to nephropathy and rejection of grafted organ. In this study, prevalence of this virus in renal allograft recipients is discussed before and after transplantation. This crosssectional study performed on 78 renal recipient cases. Blood and urine samples of patients were collected three times; before graft, one month following operation and four months after receiving the graft. All the patients were taking similar drug regimen. The extracted DNA of the samples was investigated by double PCR and semi-nestedPCR. PCR results were analyzed by SPSS software version 11.5 and Mac Nemar test. Out of 78 samples collected from kidney transplanted cases, five urine specimens (6.4%) were positive for BK virus, 10 urine samples (12.8%) turned out as positive for this virus one month after operation and 30 of urine specimens (38.5%) became positive for BK virus four months post-transplantation. Of 78 plasma samples of the same cases, none of them was positive for BK virus before transplantation. One plasma specimen (1.3%) turned out as positive for BK virus and 16 plasma samples (20.5%) were positive for this virus four months after grafted kidney. The difference between the results of the urine samples collected before and four months after kidney transplantation from the patients, was statistically significant (P<0.05). Based on the gleaned data it is concluded that BK virus infection increased in a considerable fraction of kidney transplant patients. Therefore, investigation for reactivation of BK virus is recommended in these patients after kidney graft.
Difference between Risk Factors of Common Ischemic Brain Strokes on Anterior and Posterior Circulation

Background and purpose: Ischemic brain stroke is one of the most common neurologic diseases and the second cause of death among adults. There is currently no information on the relationship between risk factors influencing anterior and posterior circulation. The most common ischemic strokes occur in the (anterior circulation) AC, while strokes occurring in the posterior circulation (PC) are more severe. We sought to explore the differences between risk factors of common ischemic brain strokes on AC and PC. Materials and methods: In this prospective descriptive study, we evaluated 200 patients referring to Sari Bualisina and Behshahr Imam Hospitals. Strokes in AC and PC were diagnosed by clinical and neuroimaging findings including brain CT Scanning and MRI. Pre-stroke cerebrovascular risk factors were recorded for each patient including hypertension, diabetes mellitus, hyperlipidemia, and smoking. Results: Among the patients 40.4% had hypertension, 45.2% were diabetic, 33.3% were hyperlipidemic, 14.7 % had ischemic heart disease and 7.7% were smokers. The effect of age and sex was not significant between circulations. The prevalence of hypertension as a major risk factor of stroke and diabetes mellitus was higher in patients with PC stroke compared to patients with AC stroke (P<0.05). The co effect of diabetes mellitus and hypertension did not have any significant effect on type of circulation. The prevalence of hyperlipidemia was five times higher in patients with AC stroke (P<0.05). No any significant difference was seen between smoking and ischemic heart diseases and the type of circulation. Conclusion: The prevalence of hypertension and diabetes mellitus as major risk factors of stroke resulted in more PC strokes. Therefore, controlling the risk factors is of great importance to reduce the rate of such strokes.
Hypoglycemic Activity of Ethanolic Extract of Solanum nigrum Linn. Leaves on Alloxan Induced Diabetes Mellitus in Rats

Diabetes is a metabolic disorder associated with hyperglycemia and caused by defect in insulin secrtion. Past few year some of the new bioactive drug isolated from plants showed anti- diabetic activity in clinical therapy . Hypoglycemic effect of these plant is due to their ability to restore the function of pancreatic β cells by causing an increase in insulin output or inhibit the intestinal absorption of glucose. Hence treatment with herbal drugs has an effect on protecting β cells and smoothing out fluctuation in glucose level. In present study we have screened alcoholic extracts of Solanum nigrum leaves for hypoglycemic effect in Albino rats. Different doses of alcoholic extract 50, 100, 200, 400 mg/kg of body weight were employed to evaluate alloxan induced diabetes with reference to standared Glibenclamide. Results indicated the alcoholic extract of leaves possesses significant hypoglycemic effect in dose dependent manner.
P.I.C.U., H.D.U., A.O.A. What treatment do we provide? Current descriptions of the function of intensive care for inpatient psychiatric health care.

Purpose – This paper adds to growing research of psychiatric intensive care units (PICU) by recounting descriptions of psychiatric intensive care settings and discusses the perceptions held by nurses of the organisational interfaces, arrangements and provisions of care in these settings. Design/methodology/approach – Data gathered from focus groups held with nurses from two PICUs was used to establish terminology, defining attributes, related concepts, antecedents, values, processes and concepts related to current practices. A literature search was conducted to permit a review of the conceptual arrangements and contemporary understanding of intensive care for people experiencing acute psychiatric illness based on the perspectives held by the nurses from the focus groups. Findings – Dissonance between service needs and the needs and management of individual patients overshadow strategies to implement comprehensive recovery-oriented approaches. Three factors are reported in this paper that influence standar.
Effectiveness of Pelvic Floor Muscle Exercise and Bladder Training In Stress Urinary Incontinence and Low Back Discomfort-A Case Study

Background: In women urinary incontinence frequently occurs during stress situations, called stress urinary incontinence and it is associated with involuntary urinary leakage on sudden physical exertion such as sneezing or coughing. It is frequently seen that stress urinary incontinence is associated some degree of discomfort around low back region. Pelvic floor muscles are known to assist in the control of continence through stabilization of the bladder neck and increase of the intra-urethral pressure. The aim of this study was to identify the role of pelvic floor muscles strengthening to control the stress urinary incontinence along with low back discomfort. Method: Patients with stress urinary incontinence previously diagnosed by the physician were included in study. Variables such as age, sex, height, body weight and body mass index were evaluated. A self assessed questionnaire was provided to the patient at the day before and after intervention (six week) to measure the degree of severity. Result shows a significant improvement in urinary incontinence at the end of 6 th week (p<0.05). The mean improvement in incontinence was 8.04 ± 1.02 and in low back discomfort it was 2.12 ± 0.48. Conclusion: It is proposed that conservative treatment including pelvic floor muscles strengthening may be effective as well as less expansive and easily manageable in management of stress urinary incontinence.
Subcutaneous IgG Replacement Therapy by Push in 32 Patients with Primary Immunodeficiency Diseases in Argentine

Introduction: Regular replacement with immunoglobulin infusions is the mainstay of treatment in the majority of primary immunodeficiencies. Several studies showed that Subcutaneous Immunoglobulin (SCIG) has similar efficacy to Intravenous Immunoglobulin (IVIG) in preventing infections in PID patients. Here we report effectiveness, safety and tolerance of SCIG replacement therapy by push in 32 pediatric and adult patients with humoral PID in Argentina. Results: We describe 32 patients that received SCIG treatment between July 2011 and May 2012. 17 male and 15 female from 2 Immunology Centers; aged from 8 months to 40 years (median: 11 years). 30 patients previously received IVIG treatment. Among them, fifteen received 9 months of SCIG treatment administered by pump. The other 2 patients started the immunoglobulin replacement treatment directly with SCIG by push. The mean dose of SCIG was 133 mg/kg/week (range 100-192). The annual rate of any infection was 1, 2 infection/year/patient for subcutaneous treatment. The frequency of adverse effects was 0.02% with the SCIG. At the end of the study, all patients chose SCIG home-therapy regimen and referred much more comfort with SCIG by push. Conclusion: Self-administered subcutaneous immunoglobulin therapy by push is an effective and safe alternative therapy for patients with PID.
Obstetric and non-obstetric factors related to labour pain

Abstract The pain associated with childbirth was rated by 104 women, (a) during the first stage or labour and (b) 24–48 hrs after delivery. The nature and intensity of this pain was analysed in terms of a number of obstetric and non-obstetric factors many of which affected the womens' perception of labour pain. Parity, duration of the second stage of labour, artificial rupture of the membranes, Pethidine and Entonox use, attendance at ante-natal classes, expectations of labour, desirability of pregnancy and the stressfullness of the birth were all significantly associated with variations in the intensity labour pain. Age, social class, miscarriage, duration of the first stage of labour, syntocinon use and the presence of the husband at the birth were not significantly related to the intensity of labour pain.
Central Hypoventilation Syndrome Complicated with Lateral Medullary Infarction after Endovascular Treatment of the Vertebral Artery Dissecting Aneurysm: A Case Report

Lateral medullary infarction rarely leads to central hypoventilation syndrome (CHS). CHS is a life-threatening disorder characterized by hypoventilation during sleep. We report the first case of CHS as a complication of lateral medullary infarction after endovascular treatment. A 65-year-old man presented twice with severe headache. Computed tomography revealed subarachnoid hemorrhage and cerebral angiography showed a right vertebral dissecting aneurysm involving the posterior inferior cerebellar artery. After emergent endovascular patent artery occlusion, he developed Wallenberg syndrome and experienced apnea and a conscious disturbance episode due to CHS on postoperative days 6 and 16. Intensive respiratory care including intubation, tracheostomy, mechanical ventilation, and rehabilitation prevented subsequent recurrence of apnea and the CHS resolved completely. CHS after unilateral medullary infarction involving respiratory centers tends to occur in the acute and subacute phase and may be lethal without careful respiratory management.
The Vidian Canal: Radiological Features in Japanese Population and Clinical Implications

The vidian canal (VC), a bony tunnel in which the vidian artery and nerve pass, has been widely known as an important landmark to identify the anterior genu of the petrous carotid artery (AGPCA) especially during lateral extended endoscopic endonasal approachs (LEEEAs). The objectives of this study in the Japanese population are to describe the radiological anatomic features and relationships between VC and its surrounding structures, and discuss the clinical implications. We studied 231 high-resolution computed tomography (CT) scans with a slice thickness of 0.5 mm. All the patients had known sellar or parasellar pathologies but without any involvement of VC. The following VC-related parameters were examined: its length, relationship to AGPCA, course from the pterygopalatine fossa to the carotid canal, its position relative to the medial pterygoid plate and pneumatization pattern of the sphenoid sinus. Mean length of VC is 14.6 mm. There is more tendency of straight-running VC compared to other populations. VC locates infero-lateral to AGPCA in all the cases. The protrusion of VC and the paraclival carotid artery to the sphenoid sinus, as well as well-pneumatization of the sinus is also observed more frequently in almost a half of the population. Surgeons who perform LEEEAs in Japanese patients must know these anatomical features. The characteristics particular to Japanese populations may facilitate better identification of VC and exposure to AGPCA intraoperatively.
Migraine and Risk of Stroke: Review of Current Evidence

Context: Migraine is a kind of primary headache that affects 10% to 20% of people worldwide. Recent studies have shown that migraines can be involved in strokes incidences, especially ischemic strokes.Hence, the current study aimed to review evidence in relation to migraine and risk of stroke. Evidence Acquisition: A literature search was done for related articles dated between 1993 and 2013 on PubMed, Science Direct, Embase, Web of Science and Scopus for both English and non-English language articles by entering “migraine”, “migraine with aura”, “headache” and “ischemic and hemorrhagic stroke” as keywords. Results: In most evaluated studies, there was a positive association between migraine with aura (MA) and strokes incidences, especially ischemic strokes. Moreover, patients with high frequency of migraine attacks had greater odds of having a stroke compared with those who had low frequency of migraine attacks. Also, the association between migraine and stroke was more significant in subjects under 45 years old. Some migraine symptoms such as vomiting and nausea had a protective role in the development of ischemic strokes. Conclusions: Migraine, especially MA, is a risk factor for incidences of strokes, especially ischemic strokes. However, due to conflicting results on the association between different types of migraine and stroke, more studies are needed in this field.
Prognostic Value of Total Lymph Node Identified and Ratio of Lymph Nodes in Resected Colorectal Cancer

Background: The extent of lymph node involvement is the most significant prognostic indicator in resected locoregional colorectal cancer. Objectives: This study aimed to investigate the prognostic value of total lymph nodes identified and ratio of lymph nodes in resected colorectal cancer. Patients and Methods: Two hundred seventy five patients with histologically proven resected locoregional invasive colorectal adenocarcinoma from 2003 to 2011 were included. All patients were treated with standard surgical resection for their colorectal cancer. Patients with incomplete data, or unresectable tumors or distant metastases were excluded from the study. All potential prognostic variables were evaluated for their impact on the local control, disease-free, and overall survival rates. Results: Of the 275 patients, 162 were men and 113 were women with a median age of 54 (range 23-84) years. The mean total lymph nodes were significantly higher in colon cancer than rectal cancer (11 versus 7.5, P = 0.001). In node positive (stage III) patients, the mean lymph nodes ratio was 0.5 for rectal cancers and 0.37 for colon cancers respectively showing a nonsignificant (P = 0.05) trend toward higher lymph nodes ratio in rectal cancer patients. In univariate analysis, the mean total number of lymph node identified was a prognostic factor for 5-year disease free (P = 0.04) and overall survival (P = 0.02) rates. In node positive patients, lymph nodes ratio was a prognostic factor for 5-year local control (P = 0.04), disease free survival (P = 0.01), and overall survival (P = 0.01) rates. On multivariate analysis, advanced primary tumor stage, rectal primary site and the presence of perineural invasion were independent adverse prognostic factors for overall survival. Conclusions: Total lymph nodes identified and ratio of lymph nodes are associated with oncological outcomes outcomes in patients with colorectal cancer.
Cardiopulmonary Exercise Testing in Children

The cardiopulmonary exercise test (CPET) is a noninvasive assessment that provides valuable insight into the health and functioning of the pulmonary, cardiovascular and muscular systems. A number of key variables are obtainable from the CPET which reflect varying degrees of pathophysiology and can provide valuable information on the cardiopulmonary function of a child. The response of the child to the acute bout of exercise of the CPET is quite distinctive from that of adults. In this review we describe the CPET in children, its assessment and interpretation. Available data on Hong Kong children are presented wherever possible.
The Effects of Nurse's Communication and Self-Leadership on Nursing Performance

Purpose: The study is to investigate the effect of communication and self-leadership on nursing performance. Methods: The subjects of study were composed of 358 nurses at a G city university hospital, tested with structured questionnaire from September 15 to 30, 2010. The collected data were analyzed with ANOVA, Pearson`s correlation coefficients and multiple regression analysis. Results: The level of communication, self-leadership, and nursing performance was 3.37, 3.38 and 3.70 respectively in average. The variables showing significant difference in communication were as follows: age, marital status, religious status, education, monthly income, work department and work experience. Also, the variables in nursing performance were as follows: age, marital status, religious status, education, education, monthly income, position, working department and work experience. Communication, self-leadership and nursing performance of nurse showed significant positive correlation. Nursing performance was positively correlated with monthly income, when it exceeded 2.01 million won, career experience and self-leadership (p
