A Literature Review of Homelessness and Aging: Suggestions for a Policy and Practice-Relevant Research Agenda

RÉSUMÉ Le sans-abrisme chez les personnes âgées est une préoccupation croissante à travers le Canada et devrait augmenter avec le changement démographique (Crane & Warnes, 2010; Culhane, Métraux, Byrne, Stino, et Bainbridge, 2013). Pourtant, les connaissances actuelles, les politiques et les pratiques concernant le sans-abrisme ont tendance largement de se concentrer sur des populations plus jeunes. De même, la recherche et les politiques sur le vieillissement en général négligent le sans-abrisme. Les réponses au problème de sans-abrisme chez les personnes âgées doivent répondre aux besoins complexes liés à la santé, la sécurité du revenu et le logement. Basé sur un examen exhaustif de la littérature, cet article présente les domaines de recherche afin d'éclairer les politiques, les stratégies et les services pour les divers groupes des aînés sans-abri. Nous clarifions les intersections du vieillissement et du sans-abrisme; examinons les statistiques pertinentes, y compris la prévalence estimée; discutons des voies et des variations de l'expérience; et determinons les lacunes dans les connaissances. Nous concluons par un appel à un programme de recherche inclusive qui aidera à créér des politiques et des pratiques visant à réduire et finalement à éliminer le sans-abrisme chez les personnes âgées au Canada. ABSTRACT Homelessness among older people is a growing concern across Canada and is expected to rise with demographic change (Crane & Warnes, 2010; Culhane, Metraux, Byrne, Stino, & Bainbridge, 2013). Yet current knowledge, policies, and practices on homelessness largely focus on younger populations. Likewise, research and policies on aging typically overlook homelessness. Responses to homelessness among older people must address complex needs related to health, income security, and housing. Based on a comprehensive literature review, this article outlines the existing and needed research with regards to homelessness among older people. We clarify the intersections of aging and homelessness; review the relevant statistics, including estimated prevalence; discuss pathways and variations in experience; and identify gaps in knowledge. We conclude with a call for an inclusive research agenda that will help build policies and practices to reduce and ultimately to eliminate homelessness among older people in Canada.
A case-control study of HIV seroconversion in health care workers after percutaneous exposure. Centers for Disease Control and Prevention Needlestick Surveillance Group.

BACKGROUND The average risk of human immunodeficiency virus (HIV) infection after percutaneous exposure to HIV-infected blood is 0.3 percent, but the factors that influence this risk are not well understood. METHODS We conducted a case-control study of health care workers with occupational, percutaneous exposure to HIV-infected blood. The case patients were those who became seropositive after exposure to HIV, as reported by national surveillance systems in France, Italy, the United Kingdom, and the United States. The controls were health care workers in a prospective surveillance project who were exposed to HIV but did not seroconvert. RESULTS Logistic-regression analysis based on 33 case patients and 665 controls showed that significant risk factors for seroconversion were deep injury (odds ratio= 15; 95 percent confidence interval, 6.0 to 41), injury with a device that was visibly contaminated with the source patient's blood (odds ratio= 6.2; 95 percent confidence interval, 2.2 to 21), a procedure involving a needle placed in the source patient's artery or vein (odds ratio=4.3; 95 percent confidence interval, 1.7 to 12), and exposure to a source patient who died of the acquired immunodeficiency syndrome within two months afterward (odds ratio=5.6; 95 percent confidence interval, 2.0 to 16). The case patients were significantly less likely than the controls to have taken zidovudine after the exposure (odds ratio=0.19; 95 percent confidence interval, 0.06 to 0.52). CONCLUSIONS The risk of HIV infection after percutaneous exposure increases with a larger volume of blood and, probably, a higher titer of HIV in the source patient's blood. Postexposure prophylaxis with zidovudine appears to be protective.
IMAGE RESTORATION USING SPARSE REGULARISATION

In this project paper we will present a method to improve the quality of given images. In particular blind deconvolution will be applied to deblur the images. Blind deconvolution is an undefined issue and should be illuminated utilizing regularization methods. The steps involved are: first, an image blur identification index is calculated to assess the sharpness of the image. The aforementioned index is used in determining whether the following procedure should be performed or not. Second, a normalized sparse regularization blind deconvolution technique is used to recover the image. And lastly, we check for quality using various quality assessment algorithms with luminance, contrast and structure to evaluate the result of recovered image. Experiment result show that the proposed blur identification algorithm and the quality assessment methods are effective in upgrading the efficiency of recovering the image while guarantying a true output.

Aromatase activity in larval gonads of Pleurodeles waltl (Urodele Amphibia) during normal sex differentiation and during sex reversal by thermal treatment effect.

Estrogens are involved in gonadal differentiation in birds and in reptiles with temperature-dependent sex determination, suggesting a key role for aromatase, the enzyme complex converting androgens to estrogens. Pleurodeles waltl is an amphibian with ZZ/ZW genotypic sex determination but gonadal differentiation is thermosensitive. The sexual phenotype is in conformity with the sexual genotype at ambient temperature (20 +/- 2 degrees), but ZW animals are sex-reversed in functional males when larvae are reared at 32 degrees from stage 42 to stage 54 (thermosensitive period). Histological sexual differentiation of gonads begins at stage 53. Aromatase activity was measured either in the gonadmesonephric complexes (stages 47 to 52) or in the gonads (stages 53 to 56) of ZZ and ZW larvae reared at ambient temperature or at 32 degrees and of ZW larvae shifted at stages 53, 55, or 56 from ambient temperature to 32 degrees for 48 hr. At ambient temperature, aromatase activity was detected, at low levels, in gonad-mesonephric complexes of both ZZ and ZW larvae at stages 47 and 50. At stage 52, it was significantly higher in ZW individuals than in ZZ ones. Then it remained low in gonads of ZZ males, whereas it markedly increased in gonads of ZW females. At 32 degrees, the gonad-mesonephric complexes (stage 52) and the gonads (stages 53 to 56) of ZW larvae had low aromatase activity similar to that in ZZ individuals. The exposure to 32 degrees for 48 hr of ZW individuals significantly decreased gonadal aromatase activity during the thermosensitive period (shift at stage 53) but not after the thermosensitive period (shifts at stages 55 and 56).

Phenazopyridine for Evaluation of Ureteral Patency: A Randomized Controlled Trial

OBJECTIVE: To evaluate the usefulness of phenazopyridine for confirmation of ureteral patency during intraoperative cystoscopy. METHODS: We conducted a randomized controlled trial comparing use of phenazopyridine with no medications for evaluation of ureteral patency during intraoperative cystoscopy in women undergoing pelvic surgery. The primary study outcome was time to visualize ureteral urine efflux. To detect a 3-minute difference with &agr; of 0.05 using a two-sided, two-sample t test and &bgr; 0.80 required 98 patients equally divided into two groups. RESULTS: A total of 104 women were randomized from April to December 2015. Patients in the treatment group tended to be older (P=.02); otherwise, study groups were similar. Time to visualize ureteral urine efflux did not differ between study groups with a mean time of 2 minutes 40 seconds (±2 minutes 38 seconds) in the control group and 2 minutes 53 seconds (±4 minutes 35 seconds) in the treatment group (P=.77). Regarding the surgeon survey, surgeons felt less frustrated and impatient in visualization of ureteral urine efflux in the treatment group compared with the control group (mean response 1.5±0.8 in treatment compared with 2.0±1.0 in control, P=.007), and surgeons felt that the cystoscopy took too long more often in the control than in the treatment group (1.7±0.9 in treatment compared with 2.1±1.0 in control, P=.02). Trial of void result differed significantly between groups with fewer patients in the treatment group failing a void trial (P=.04). There were no adverse events related to phenazopyridine use. CONCLUSION: Preoperative phenazopyridine is a useful and cost-saving medication for use in planned cystoscopy for evaluation of ureteral patency.

Behaviour disorder in monosomy 10qter.

Monosomy for the terminal segment of the long arm of chromosome 10 has been reported in 11 cases as summarised recently by Shapiro et al.' The phenotype of these patients has tended to conform to a consistent pattern with triangular face and moderate mental retardation. We now report a child who shows these features in association with severe behavioural disturbance. The seven year old male proband was the only child of healthy unrelated parents. His mother and father were aged 25 and 34 years, respectively, at the time of his birth. He was delivered at 41 weeks' gestation weighing 3-00 kg and had mild meconium aspiration at birth. He sat at seven months and began walking at 21 months when concern first arose because of speech delay and short stature. Hearing assessment indicated bilateral mixed sensory and conductive loss. On assessment aged five years, height (97 cm), weight (14 kg), and head circumference (47-5 cm) all fell below the 3rd centile. He had a triangular face (fig 1) with dolichocephaly, prominent nasal root with beaked nose and flared nares, long philtrum, small pointed jaw, and convergent strabismus. Other findings included bilateral fifth finger clinodactyly, limitation of extension of both elbows, and undescended testes.
On the derivation of a quantum Boltzmann equation from the periodic Von-Neumann equation

Nous presentons l'equation de Boltzmann des semi-conducteurs, qui est irreversible en temps, et indiquons qu'elle peut etre derivee heuristiquement par une limite en temps grand et potentiel perturbateur petit dans l'equation de Von-Neumann (reversible). Puis nous calculons rigoureusement cette asymptotique dans le cas de l'equation de Von-Neumann sur le Tore. Nous montrons que le modele limite ainsi obtenu ne coincide pas avec le modele physique attendu. Il s'agit d'une equation de type Boltzmann, mais avec un effet de memoire en temps, de sorte qu'elle apparait reversible dans le temps. Nous commentons ce point, et proposons une description plus complete des proprietes de l'equation limite.
Big-Data Architecture for Cyber Attack Graphs Representing Security Relationships in NoSQL Graph Databases

We introduce a new modeling framework for mapping vulnerability paths through networks and associating them with observed attacker activities. We merge a complex blend of network relationships and events, such as topology, firewall policies, host configurations, vulnerabilities, attack patterns, intrusion alerts, and logs. Our persistence layer includes Neo4j, a Not Only SQL (NoSQL) database optimized for graphs. We explore how the Neo4j property-graph data model supports analysis and queries within our problem domain. For interoperability with other tools, we employ standardized cyber- security data exchange language. We show that our approach supports the same kinds of graph analytics as an existing attack graph tool, through the application of the Neo4j Cypher query language. We then extend those analytics through a much richer model of the network environment and attacker/defender activities. Our work represents the first investigation of cyber attack graph analysis based on graph databases - an important class of NoSQL database.
Knowledge management initiatives in Indian public and private sector organizations

Purpose – There is no single way of achieving business success. The concept of knowledge management (KM) builds on the existing management practices, integrating them into a philosophy for improving performance. This paper aims to understand the various dimensions of KM and how they differ in public and private sector organizations in India. It also attempts to identify the dimensions where one sector is better than the other and areas needing improvement.Design/methodology/approach – The paper uses a sample comprising 16 private and public sector organizations. A convenient sampling scheme was used. The extent of KM practices was evaluated with respect to dimensions, namely process, leadership, technology, culture and measurement.Findings – The paper empirically shows that private sector organizations fare better statistically on all dimensions compared to public sector organizations. Although the private sector is ahead of the public sector on the raw mean scores of various dimensions, it has still a lo.
Analysis and identification of phenolic compounds in Dioscorea hispida

Hydroxybenzoic acid, hydroxycinnamic acid and their derivatives were found in extracts of Dioscorea hispida Dennst tuber (Kloi tuber). Extraction was done with 60% aqueous MeOH, hydrolyzed and fractionated into fractions by SPE C18 cartridge by using aqueous MeOH (1060% MeOH). The identification was achieved by Rp HPLC and ESI-LC-MS in negative ion mode. The compounds found present in the peel were caffeic acid, chlorogenic acid, phydroxybenzaldehyde and methylester of protocatechuic acid (methoxyprotocatechuate). Only methyester of protocatechuic acid was found in the flesh of Kloi tuber. Most of the identified compounds were in the 20% MeOH fraction. Antioxidant potential of Kloi tuber was also investigated, the DPPH value for 20% MeOH peel and flesh fraction were EC50 1.05 x 10 μg/ml for the peel fraction and EC50 2.04 x 10 μg/ml for the flesh fraction. FRAP values were 3.26 x 10 μmol Fe/mg for peel and 2.93 x 10 μmol Fe/mg for flesh. The total phenol content of peel was 0.068 ± 0.04 mg GAE/mg and 0.085 ± 0.05 mg GAE/mg for flesh.
Unit commitment for combined pool/bilateral markets with emissions trading

The paper proposes a unit commitment problem formulation which models combined pool/bilateral operation as well as effects of emissions constraints and emissions trading mechanisms. In here proposed model, power outputs of generators are, on one hand, bounded by their bilateral contract commitments, and on the other side, by the amount of CO2 emissions that they are allowed to produce over time. These emissions constraints introduce additional complexity as it is becoming more important for generating units to decide on when and how much to produce, as well as to investigate how to mange their allocated CO2 permissions in the most economic way. Since the proposed formulation of the market clearing includes costs of buying and selling of CO2 allowances, it permits analysis on how emission caps and emission market prices can influence generation decisions and the resulting generation scheduling. The method is illustrated on a 5-unit system, and given examples investigate how different levels of bilateral trades, as well as amounts of CO2 allowances, may affect the market outcome.
Simultaneous Quantification of Tacrolimus and Sirolimus, in Human Blood, by High-Performance Liquid Chromatography–Tandem Mass Spectrometry

In this paper the authors present a validated method for the simultaneous analysis of tacrolimus and sirolimus in human blood by high-performance liquid chromatography–electrospray tandem mass spectrometry. Blood samples (500 &mgr;L) were prepared by C18 solid-phase extraction. Mass spectrometric detection was by selected reaction monitoring. The assay was linear for both compounds over the range 0.25–100 &mgr;g/L (r2 > 0.996, n = 7). At the limit of quantification (0.25 &mgr;g/L), for both sirolimus and tacrolimus, the interday imprecision was <3% and the analytical recovery was between 97.0% and 102%, respectively. The interbatch and intrabatch coefficients of variation of the method for both analytes, at the three quality control concentrations (0.5, 20, and 80 &mgr;g/L), were <16% and <10%, respectively. The analytical recovery, at the three control concentrations, ranged from 99.2% to 104% of the nominal concentration. The mean absolute recovery (±standard deviation) of tacrolimus, sirolimus, and internal standard was 82 ± 7%, 89 ± 12%, and 77 ± 8%, respectively (n = 12). In conclusion, the method presented can be used for simultaneous determination of tacrolimus and sirolimus and will aid in pharmacokinetic studies and therapeutic drug monitoring of these drugs. Furthermore, this method has economic benefits in the clinical setting where these drugs are coadministered.
Clinical and endoscopic spectrum of upper gastrointestinal manifestations in HIV patients.

BACKGROUND Human Immunodeficiency Virus (HIV) infected patient frequently report upper gastrointestinal (GI) symptoms; however their prevalence and diagnostic approach is not well known. OBJECTIVE The objective of this study was to study clinical, endoscopic and histopathological changes in HIV infected patients with upper GI symptoms and their correlation with CD4 count. MATERIALS AND METHODS We evaluated 50 HIV infected patients who presented to M.S. Ramaiah hospital with upper GI symptoms. All patients answered questionnaire assessing upper GI symptoms and underwent upper GI endoscopy. Mucosal biopsy was taken wherever mucosal abnormality seen. RESULTS In our study, the mean age of patients was 40.98 yrs, of which 80% were males. Vomiting (36%), epigastric pain (36%), weight loss (34%) and anorexia (34%) were the predominant symptoms. Esophagogastroduodenoscopy (EGD) findings revealed--Oesophageal candidiasis in 28.0%, esophagitis in 22.0%, gastritis in 20.0%, duodenitis in 14%, normal upper GI mucosa in 18 % patients. Oesophageal candidiasis was the most common finding on histopathological examination and the mean CD4 count was 157.92 cells/μl. CONCLUSION Vomiting, epigastric pain, weight loss and anorexia were most frequent symptoms. Oral candidiasis was the most common oral lesion. Oesophageal candidiasis, oesophagitis and oesophageal ulcers were the common findings on EGD. Patient with CD4 count less than 200 cells/μl had more frequent upper GI mucosal involvement than in patients with CD4 count more than 200. Majority of the patients with GI symptoms had upper GI mucosal changes and opportunistic infections. Thus endoscopic and histopathological evaluation is advisable for the early diagnosis and treatment of upper GI complications in patients with HIV infection.
Improving Quality through Value Stream Mapping: A Case Study of a Physician's Clinic

Abstract As organizations look to improve overall systems to reduce costs and improve throughput, lean principles are being more widely implemented. These lean initiatives began in manufacturing, but have spread through other parts of the economy, including health care. This paper reports on a value stream mapping project in a small medical clinic that resulted in recommendations that would significantly lower patient wait time and increase patient throughput. The new system can increase the capacity of the office without adding people or equipment, lower waiting times for people with scheduled appointments, increase the opportunity for patients without appointments to be seen at the last minute, and lower the stress levels for the clinic's staff.
A Randomized Controlled Trial of Tissue Adhesive Versus Sutures in the Closure of Port-Site Incisions in Laparoscopic Surgery

Cyanoacrylates have been recognized since before the 1960s as excellent tissue adhesives. They are easy to use, cost-effective, and cosmetically favorable. There are no studies from India reporting the use of tissue adhesives in laparoscopic surgery. We carried out a prospective, interventional, randomized trial of non-absorbable simple interrupted sutures versus 2-octyl cyanoacrylate in the closure of skin incisions in laparoscopic surgery with the primary objective of assessing the efficacy (approximation achieved) of both methods. The secondary objectives were to compare the operative time for closure, post-operative pain, infection and cost. There were 20 participants, 10 in either arm. Consenting patients undergoing elective laparoscopic surgery in a single surgical unit were included. Descriptive statistics were used on demographic data. Comparisons between the two methods were made on the basis of Southampton Wound Assessment Scale-SWAS grade for healing, Visual Analogue Scale-VAS scores for pain, intra-operative time, and cost. Apart from cost which was significantly higher for adhesive group, the groups did not differ significantly in terms of pain, wound approximation, and infection. Octyl cyanoacrylate is comparable to non-absorbable simple interrupted sutures in terms of closure time, post-operative pain, wound approximation and infection. The cost of using octyl cyanoacrylate is substantially higher than traditional suture material.
Effects of Diet on Salivary Secretion and Composition

The composition of saliva is potentially of great importance to the prevention of caries. Saliva contains buffers that tend to reduce the fall in pH that is associated with acid formation from carbohydrate by the dental plaque; it also contains urea, a substrate for base formation by dental plaque. Saliva contains at least one enzyme (amylase), which is involved in the first stages of the metabolism of starch, a component of many foods. In addition, saliva contains ions such as calcium, phosphate, and fluoride, the concentrations of which determine the pH at which tooth mineral will begin to dissolve. The main criticism that can be leveled against the majority of studies on the effects of diet on saliva is that the experimental design did not control the nondietary variables that can affect salivary flow rate or composition. These include the source of saliva, flow rate, degree of hydration of the subject, nature of the stimulus, duration of stimulation, plasma composition, the time of day at which samples are collected, and the serial dependency of saliva samples (the effect of previous stimulation on the composition of saliva collected subsequently). The importance of some of these factors has only recently been appreciated. In addition, the experimental design of previous studies rarely included a group of control subjects kept on a constant diet. The effect of nutrition on saliva was reviewed briefly by Krasse.1
