Authors: Jiménez Leticia , Arano Diana E. , Ruvalcaba José L. , Unikel Fanny 
Published: May 2014

ABSTRACTThe altarpiece dedicated to San Antonio de Padua was made of wood assembled and self-supporting structure attached to the wall. It is a straight plant altarpiece designed to withstand sculptures. This master piece belongs to the a set of Baroque altarpieces preserved in the state of Campeche and is located in San Roque Church in the City of San Francisco de Campeche, Mexico. This altarpiece was decorated following the traditional technique of the seventeenth century in Mexico, a technique derived from Spain. According to literature sources we know that the strata are the wood, the imprimatura, the pictorial strata and metal sheets that make the golden color and corladuras. The characterization of the constituent materials was of great importance for the interpretation of the constructions system and manufacture of the decoration. The present study shows the results of analysis techniques such as optical microscopy, Particle Induce X Ray Emission (PIXE), and X Ray Florescence Spectroscopy (XRF) and interpretation of the different layers constituting the altarpiece of San Antonio.
Design of Soft-Interface Materials for Highly Sensitive Bio-Sensing Devices
Authors: Takai Madoka 
Published: May 2014

ABSTRACTTwo typed bio-conjugated soft-interface for highly sensitive immunoassay was developed by integrating a phospholipid polymer. Nano-sphered surface with poly [2-methacryloyloxyethyl phosphorylcholine (MPC)-co-n-butyl methacrylate (BMA)-co-p-nitrophenyloxycarbonyl poly(ethylene glycol) methacrylate (MEONP)]: PMBN) was prepared by electrospray deposition (ESD) method. The three dimensional nano-sphered surface can be captured an antibody with high density around 860 ng/cm2. The theoretical amount of closest packed immobilized antibodies on flat surface is around 650 ng/cm2, thus large amount of antibodies were immobilized on the nano-sphere surface. The water stability of PMBN nanostructure was improved by crosslinking with 1,4-butylenediamine and by heating. Both heated and cross-linked PMBN nanostructure was not changed at all remaining high porosity after immersing in water. The specific signal in the immunoassay was enhanced with both heated and cross-linked PMBN nanostructure. The PMBN nanostructure which has high porosity and high water stability realized highly sensitive immunoassay.As the other platform, we developed a novel soft-interface consisting of a well-defined phospholipid polymer surface on which Staphylococcal Protein A (SpA) was site-selectively immobilized. The phospholipid polymer platform was prepared on silicon substrates using the surface-initiated atom transfer radical polymerization (SI-ATRP) technique. Orientation-controlled antibodies were achieved using enzymatic reactions, and these antibodies captured 1.8 ± 0.1 antigens on average, implying that at least 80% of immobilized antibodies reacted with 2 antigens. Theoretical multivalent binding analysis further revealed that orientation-controlled antibodies had antigen-antibody reaction equilibrium dissociation constants (Kd) as low as 8.6 × 10-10 mol/L, whereas randomly oriented and partially oriented antibodies showed Kd values of 2.0 × 10-7 mol/L and 1.2 × 10-7 mol/L, respectively. These findings support the significance of antibody orientation because controlling the orientation resulted in high reactivity and theoretical binding capacity.
Fractal Models and the Structure of Materials
Authors: Schaefer Dale W. 
Published: May 2014

Science often advances through the introdction of new ideas which simplify the understanding of complex problems. Materials science is no exception to this rule. Concepts such as nucleation in crystal growth and spinodal decomposition, for example, have played essential roles in the modern understanding of the structure of materials. More recently, fractal geometry has emerged as an essential idea for understanding the kinetic growth of disordered materials. This review will introduce the concept of fractal geometry and demonstrate its application to the understanding of the structure of materials.Fractal geometry is a natural concept used to describe random or disordered objects ranging from branched polymers to the earth's surface. Disordered materials seldom display translational or rotational symmetry so conventional crystallographic classification is of no value. These materials, however, often display “dilation symmetry,” which means they look geometrically self-similar under transformation of scale such as changing the magnification of a microscope. Surprisingly, most kinetic growth processes produce objects with self-similar fractal properties. It is now becoming clear that the origin of dilation symmetry is found in disorderly kinetic growth processes present in the formation of these materials.

Abstract

Purpose.
Improper storage, use, and disposal of prescribed opioids can lead to diversion or accidental poisoning. Our objective was to determine the patterns of storage, utilization, and disposal of opioids among cancer outpatients.

Patients and Methods.
We surveyed 300 adult cancer outpatients receiving opioids in our supportive care center and collected information regarding opioid use, storage, and disposal, along with scores on the CAGE (cut down, annoyed, guilty, eye-opener) alcoholism screening questionnaire. Unsafe use was defined as sharing or losing opioids; unsafe storage was defined as storing opioids in plain sight.

Results.
The median age was 57 years. CAGE was positive in 58 of 300 patients (19%), and 26 (9%) had a history of illicit drug use. Fifty-six (19%) stored opioids in plain sight, 208 (69%) kept opioids hidden but unlocked, and only 28 (9%) locked their opioids. CAGE-positive patients (p = .007) and those with a history of illicit drug use (p = .0002) or smoking (p = .03) were more likely to lock their opioids. Seventy-eight (26%) reported unsafe use by sharing (9%) or losing (17%) their opioids. Patients who were never married or single (odds ratio: 2.92; 95% confidence interval: 1.48–5.77; p = .006), were CAGE positive (40% vs. 21%; p = .003), or had a history of illicit drug use (42% vs. 23%; p = .031) were more likely to use opioids unsafely. Overall, 223 of 300 patients (74%) were unaware of proper opioid disposal methods, and 138 (46%) had unused opioids at home.

Conclusion.
A large proportion of cancer patients improperly and unsafely use, store, and dispose of opioids, highlighting the need for establishment of easily accessed patient education and drug take-back programs.

Background: Chronic kidney disease has been a worldwide public health challenge and also a risk factor for oral health. The objectives of this study are to investigate the periodontal status in Chinese patients undergoing hemodialysis (HD) and assess periodontal bone loss (BL) using cone‐beam computerized tomography (CBCT).Methods: The patients in the HD and control groups received periodontal and CBCT examinations in the same period. Age, sex, and HD details were obtained from a hospital database. Periodontal status was evaluated using the community periodontal index (CPI) and clinical attachment loss (AL). Periodontal BL was measured by the distance from the cemento‐enamel junction to the alveolar crest using CBCT. The distance between the furcation upper and lower boundaries was considered the furcation defect.Results: One hundred two patients undergoing HD and 204 control patients were enrolled. As for the demographic data and number of remaining teeth for each patient, there was no significant difference between HD and control groups. The CPI and AL showed statistical differences (P <0.001). The results of periodontal BL indicated that the patients undergoing HD had significantly more BL at their mandibular first premolars and first molars than did patients in the control group (P <0.01) at every site except the disto‐buccal one (P <0.05). As for the furcation defects, the distance for the patients undergoing HD was nearly double that of the patients in the control group (P <0.001).Conclusion: Compared with the generally healthy population, periodontitis and periodontal BL were significantly more severe in the Chinese patients undergoing HD.

Background: The objective of this study is to characterize the association between metabolic syndrome (MetS) and periodontitis in women, for which there is limited evidence.Methods: Cross‐sectional associations between MetS and periodontitis were examined in 657 postmenopausal women aged 50 to 79 years enrolled in a periodontal disease study ancillary to the Women's Health Initiative Observational Study. Whole‐mouth measures of alveolar crest height (ACH), clinical attachment level (CAL), probing depth (PD), gingival bleeding, and supragingival plaque and measures to define MetS using National Cholesterol Education Program criteria were from a clinical examination. Study outcomes were defined as: 1) mean ACH ≥3 mm, two sites ≥5 mm, or tooth loss to periodontitis; 2) ≥2 sites with CAL ≥6 mm and ≥1 site with PD ≥5 mm; 3) gingival bleeding at ≥50% of sites; and 4) supragingival plaque at ≥50% of sites. Logistic regression was used to estimate odds ratios (ORs) and 95% confidence intervals (CIs).Results: In unadjusted analyses, MetS (prevalence: 25.6%) was significantly associated with supragingival plaque (OR = 1.74; 95% CI: 1.22 to 2.50) and non‐significantly associated with periodontitis defined by ACH (OR = 1.23; 95% CI: 0.81 to 1.85) and gingival bleeding (OR = 1.20; 95% CI: 0.81 to 1.77). Adjustment for age, smoking, and other confounders attenuated observed associations, though supragingival plaque remained significant (OR = 1.47; 95% CI: 1.00 to 2.16; P = 0.049). MetS was not associated with periodontitis defined by CAL and PD.Conclusions: A consistent association between MetS and measures of periodontitis was not seen in this cohort of postmenopausal women. An association between MetS and supragingival plaque requires further investigation.

Published: May 2014

There is still a debate as to whether radiological guidance is needed for intra-articular hip injections. The aim of this study was to evaluate correct needle positioning for the hip joint performed with a non-radiological method and confirmed on arthrogram under image intensifier.
Patients listed for diagnostic and therapeutic hip joint injections were included in our study. Eighty seven patients (100 hips) underwent injections with the non-radiological method using anatomical landmarks. Fluoroscopy and arthrogram were then used to confirm the needle position. The primary outcome measure was the success rate of correct positioning of the needle in hip joint by the non-radiological method, as confirmed on arthrogram under image intensifier. The secondary outcome measures were relationship between the grade of the surgeon and patient BMI to success rate of hip injections by the non-radiological method.
Overall success rate with the non-radiological method was 67%. Consultants were 77.1% successful and registrars 57.7% (P = 0.039). The average body mass index (BMI) in the successful group was 28.45 (SD = 5.21) and 32.03 (SD = 4.84) in the unsuccessful group (p=0.001). Success was further improved to 88% when performed by a consultant in low BMI (< 30) patients.
This prospective study shows that hip injections can be performed with reasonable success without radiological guidance. Experienced surgeons may be able to perform this procedure in outpatient clinics in normal BMI patients; thereby reducing costs and the need for bed space.

Abstract
Objective—To compare the nutrient composition of commercially available dog milk replacers with that of dog milk.
Design—Prospective, cross-sectional study.
Sample—5 dog milk samples and 15 samples of commercial dog milk replacers.
Procedures—Dog milk and milk replacers were analyzed for concentrations of total protein, essential amino acids, sugars, total fat, essential fatty acids, calcium, and phosphorus. Energy density was calculated. Results from milk replacers were compared with the range of the concentration of each nutrient in milk samples from mature dogs as well as the National Research Council (NRC) recommendations for puppy growth.
Results—Milk replacers varied widely in caloric density and concentration of nutrients such as calcium, protein, and fat. Calcium concentration was lower in 14 of 15 milk replacers than in the dog milk samples. Docosahexaenoic acid was undetectable in 12 of 15 milk replacers but present in all dog milk samples. All milk replacers had numerous essential nutrients outside of the range of the dog milk samples, and many had concentrations of amino acids, essential fatty acids, calcium, and phosphorus less than the NRC minimal requirement or recommended allowance. Compared with NRC recommendations, some dog milk samples had concentrations of total protein, linoleic acid, calcium, or phosphorus less than the recommended allowance.
Conclusions and Clinical Relevance—Results suggested that there was substantial variation in nutrient composition of 15 dog milk replacers and that some products were closer approximations of dog milk than others. Nearly all products would benefit from more appropriate calcium, amino acids, and essential fatty acids concentrations and better feeding directions.
Cutaneous lymphoma of the tarsus in cats: 23 cases (2000–2012)

Published: May 2014

Abstract
Objective—To determine features of lymphoma of the tarsus in cats.
Design—Multi-institutional retrospective study.
Animals—23 cats with cutaneous lymphoma of the tarsus.
Procedures—Veterinary oncologists were requested to submit cases fitting the following criteria: histologically or cytologically confirmed lymphoma with a location at or near the tarsus and described as subcutaneous or mass-like. Data regarding breed, sex, age, FeLV and FIV status, and reason for evaluation were collected. Results of staging tests, location of the tumor, immunophenotype, and histopathologic description were recorded. Type of treatments, outcome, survival time, presence or absence of progressive disease, and cause of death or reason for euthanasia were also recorded.
Results—Most cats were older, with a median age of 12 years (range, 7 to 18 years). No association with positive retroviral status was found. Popliteal lymph node involvement at diagnosis was reported in 5 cats, and a suspicion of lymphoma at a different site on the basis of results of abdominal ultrasonography was reported in 4 cats. Treatments were variable and included corticosteroids alone (n = 2), chemotherapy (9), radiation and chemotherapy (7), or surgery with or without chemotherapy (5). Thirteen cats were reported to have lymphoma at a different site at the time of last follow-up, death, or euthanasia. Median survival time for all cats in the study was 190 days (range, 17 to 1,011 days).
Conclusions and Clinical Relevance—Results suggested that tarsal lymphoma is an uncommon manifestation of lymphoma in cats, and in this study was most commonly nonepitheliotropic and of high grade as determined on histologic evaluation. Systemic involvement was identified; therefore, thorough staging is recommended prior to initiating treatment. Future studies are warranted to evaluate effective treatment protocols.
Predictive modeling for preventive Archaeology: overview and case study
Authors: Danese Maria , Masini Nicola , Biscione Marilisa , Lasaponara Rosa 
Published: May 2014

AbstractThe use of GIS and Spatial Analysis for predictive models is an important topic in preventive archaeology. Both of these tools play an important role in the Support Decision System (SDS) for archaeological research and for providing information useful to reduce archaeological risk. Over the years, a number of predictive models in the GIS environment have been developed and proposed. The existing models substantially differ from each other in methodological approaches and parameters used for performing the analysis. Until now, only few works consider spatial autocorrelation, which can provide more effective results. This paper provides a brief review of the existing predictive models, and then proposes a new methodological approach, applied to the neolithic sites in the Apulian Tavoliere (Southern Italy), that combines traditional techniques with methods that allow us to include spatial autocorrelation analysis to take into account the spatial relationships among the diverse sites.
Influence of the spatial resolution of satellite-derived vegetation parameters on the biogenic Volatile Organic Compounds (VOC) emission modeling
Authors: Silveira Carlos , Tchepel Oxana 
Published: May 2014

AbstractVegetation is a natural source of Volatile Organic Compounds (VOC) that plays an important role in atmospheric chemistry. The main objective of the current study is to implement a model to quantify process-based VOC emissions from plants that focuses on the relationship between the sensitivity of VOC emission estimates to spatial resolution data, based on scientific knowledge and vegetation dynamics derived from satellite observations. The Normalized Difference Vegetation Index (NDVI) and Leaf Area Index (LAI) were elected to examine this issue using different resolutions of satellite-derived products: 22m from the DEIMOS-1 satellite, and 250m and 1000m provided by MODIS. The study is focused on an area of 80×80km2 in Portugal for 2011. Detailed land cover and meteorological data are also included in the emission quantification algorithm. The primary outcomes were determined using a multi-scale analysis showing spatial and temporal variations in the vegetation parameters and modeling results. The results confirm that the emissions model is highly sensitive to the spatial resolution of the satellite-derived data, resulting in about a 30% difference in total isoprene emissions for the study area.
GERONTOLOGICAL NURSING: Overcoming Barriers to Preparation and Practice
Authors: Manuel Patricia , Haussler Susan C 
Published: May 2014

Because nurses are the principal managers of health care for the elderly, it is crucial to examine the barriers that affect educational programs that prepare nurses to practice as both clinicians and administrators in gerontology. Until the barriers are removed, it will be impossible for educational programs to provide the quality and quantity of nurses needed to practice in this specialty.
This article examines the barriers that prevent nurses from both practicing in the long-term care setting and pursuing graduate education in gerontology and long-term care. Additionally, strategies for change and collaboration between the service/practice setting and educational programs are discussed.

DETECTION AND CORRECTION of Underweight Problems in Nursing Home Residents
Authors: Gants Ruth 
Published: May 2014

ABSTRACT
Subnormal weight in the elderly is a well-known phenomenon; the ramifications may result in illness and death. There are many reasons for weight loss, usually related to changes that accompany aging or against a background of acute or chronic illness.
Our goal in this study was to identify the underweight people living in our retirement facility at different functional levels and to plan and carry out nursing interventions in cooperation with the rest of the multidisciplinary team to increase their weight to within normal limits.
Of the 205 residents who live in the home, 48 (23.4%) were found to be under the lower limit of ideal weight tables. With the aid of individual care plans and calorie-rich, low-volume diets, we succeeded in increasing the weight of 29 residents to within the normal range within 2 to 12 months. Seven residents died during the experimental period, and three continuing to lose weight. The rest of the residents remained stable at their original low weight.
GENDER DIFFERENCES in Health and Health Actions Among Community-Dwelling Elders
Authors: Musil Carol M 
Published: May 2014

ABSTRACT
This secondary analysis of data from a study of elders' health examined gender differences in the psychological and physical health and the health actions made in response to specific physical complaints in a random sample of 491 communitydwelling older adults (mean age of 75.3 years). Significant gender differences in anxiety, depression, and body awareness were found, although there were no differences in self -assessed health or total number of health problems reported. There were some gender differences in the types of health problems experienced. Subjects tended to use self-care actions, particularly overthe-counter medications and home remedies, more so than professional consultation. Different patterns of care emerged for women and men, with women somewhat more inclined to use self-care and men more likely to seek professional consultation.
Tuberculosis and the Elderly: A Community Health Perspective
Authors: Gubser Virginia L 
Published: May 2014

ABSTRACT
Tuberculosis is an ancient disease which has had a resurgence in the United States. Many elderly clients were exposed to tuberculosis as children and young adults and are still carrying the infection today. This article describes tuberculosis as it affects the elderly client in community and nursing home settings. The history, etiology, clinical manifestations, treatment, and prevention of tuberculosis infection and disease are presented. Because nurses can be very instrumental in controlling tuberculosis in the elderly, gerontological nursing implications are discussed.
LIVING WITH DEMENTIA From the Patient's Perspective
Authors: Phinney Alison 
Published: May 2014

ABSTRACT
This study describes the illness experience of dementia from the patient's perspective. Five people with Alzheimer's disease and their spouses were interviewed and observed during home visits. Thematic analysis revealed two themes: being unsure and trying to be normal. Being unsure describes people's fluctuating experience of symptoms that leaves them feeling unsure of themselves in a world that is increasingly unfamiliar. Trying to be normal describes people's efforts to counter the impact of dementia to maintain continuity in their lives. These findings point to the importance of taking into account the patient's perspective to better understand the experience of living with dementia and develop improved treatment and care practices.
