The aim of this study was to analyse the influence of stump skin problems on functioning in daily life in lower-limb amputees. A cross-sectional study was performed by means of a questionnaire containing 9 questions assessing functioning in daily life. Question scores were added to give a total score (range ...

Use of a prosthesis in lower limb amputees can lead to skin problems of the amputation stump. However, little is known about the epidemiology and type of problems experienced. We conducted a cross-sectional survey consisting of a questionnaire and a clinical assessment of the amputation stump. The aims of the ...

Kaposi's sarcoma (KS) in HIV negative patients is rare and has to be distinguished from AIDS associated KS. Two groups are at risk to develop non-AIDS related KS: elderly men mainly of Mediterranean origin and persons with iatrogenic immunosuppression. In order to define risk-groups and major clinical features we retrospectively ...

Background/Objectives: Studies on human herpesvirus 8 (HHV8) infection in patients with AIDS-associated Kaposi sarcoma (AIDS-KS), from Nigeria are lacking. We examined the seroprevalence of HHV8 infection in patients with AIDS-KS presenting to Ahmadu Bello University Teaching Hospital (ABUTH), Zaria, Nigeria, and also described their clinical presentation. A total of 20 ...

Foot problems in general and forefoot problems in particular can lead to a decrease in mobility and a higher risk of falling. Forefoot problems increase with age and are more common in women than in men. Around 20% of people over 65 suffer from non-traumatic foot problems and 60% of ...

Basal cell carcinoma (BCC) and squamous cell carcinoma (SCC) are the commonest types of non-melanoma skin cancer (NMSC). The incidence of NMSC has been increasing globally with Australia recording a 1.5-fold increase over the last 17 years. Given that Australia and New Zealand share similar latitude, sun exposure levels, population ...

Multiplicative update algorithms have proved to be a great success in solving optimization problems with nonnegativity constraints, such as the famous nonnegative matrix factorization (NMF) and its many variants. However, despite several years of research on the topic, the understanding of their convergence properties is still to be improved. In ...

We investigated the extent to which inhibition, updating, shifting, and mental-attentional capacity (M-capacity) contribute to children's ability to solve multiplication word problems. A total of 155 children in Grades 3-6 (8- to 13-year-olds) completed a set of multiplication word problems at two levels of difficulty: one-step and multiple-step problems. They ...

An acute infectious epidemic almost eliminated the St Kilda community in 1727. An epic tale of survival in adversity followed. Contemporary records reveal atypical features, suggesting a speculative alternative.

Nonnegative matrix factorization (NMF) is useful to find basis information of nonnegative data. Currently, multiplicative updates are a simple and popular way to find the factorization. However, for the common NMF approach of minimizing the Euclidean distance between approximate and true values, no proof has shown that multiplicative updates converge ...

Many problems in neural computation and statistical learning involve optimizations with nonnegativity constraints. In this article, we study convex problems in quadratic programming where the optimization is confined to an axis-aligned region in the nonnegative orthant. For these problems, we derive multiplicative updates that improve the value of the objective ...

ABSTRACT: Queerness is now global. Many emerging economies of the global South are experiencing queer mobilization and sexual identity politics raising fundamental questions of citizenship and human rights on the one hand; and discourses of nationalism, cultural identity, imperialism, tradition and family-values on the other. While some researchers argue that ...

This article presents several typical problems used in an introductory course in molecular biology and discusses why the problems are effective at increasing learning.

The effectiveness of premarriage education is limited by whether couples at high risk of future marital problems attend such education. In the current study, 374 newly married couples were assessed on a range of risk factors for future marital problems as well as whether they had attended marriage education. Couples ...

The advent of the new millennium has witnessed the embracing of a different perspective on global health aid. New and innovative mechanisms in health-aid financing are leading to new opportunities, focused on greater innovation, risk taking and speed. However, these opportunities might not fully materialize if the traditional approaches of ...

It's time to rethink global branding. More than two decades ago, Harvard Business School professor Theodore Levitt argued that corporations should grow by selling standardized products all over the world. But consumers in most countries had trouble relating to generic products, so executives instead strove for global scale on backstage ...

In a flurry of announcements that came just weeks before it called a federal election, the federal government doubled the funding for its domestic HIV/AIDS strategy, doubled its contribution to the Global Fund to Fight AIDS, Tuberculosis and Malaria, and announced a significant contribution to the World Health Organization (WHO) ...

The presidential initiative to increase funding for global AIDS prevention and treatment is widely seen as a groundbreaking advance. But critical time will be lost if the U.S. focuses so heavily on building its own new system, instead of using multinational organizations like the Global Fund that are ready now.

The global effort against the AIDS epidemic is stalling on the issue of resources. The main reason is that the U.S. Congress is not hearing from constituents that they care about the epidemic in poor countries (where about 90% of the cases are located); many other countries follow the U.S. ...

We propose a new method for updating units in the Hopfield model. With this method two or more units change at the same time, so as to become the lowest energy state among all possible states. Since this updating algorithm is based on the detailed balance equation, convergence to the ...

Having a multitude of different ethnic communities forces Canada's AIDS educators to use many different methods to deliver their messages. These range from an AIDS bingo game that has been used to educate natives in northern Manitoba to attempts to take AIDS education to the streets of Toronto. With AIDS ...

OBJECTIVE: Virtual bronchoscopy is a recently described technique for performing simulated bronchoscopy using data obtained from thin-section CT scans of the airways. Although the detail visible during virtual bronchoscopy can be striking, the lack of global context and physical cues can lead to disorientation for the radiologist, especially during real-time ...

The problems surrounding leishmaniasis are changing. An increase in travel, the Indian and Sudanese epidemics of visceral leishmaniasis, parasite resistance to antimony and the emergence of AIDS-related leishmaniasis have all increased the urgency for new drugs, and led to reappraisals of the old ones, as discussed here by Piero Olliaro ...

Fear of AIDS is being managed better in places of business where education is provided to employees. This education results in a ...

Newspapers have the potential to take a leading role in AIDS education in Africa. With their relatively small circulations, they mainly reach educated urban citizens, a population particularly hard hit by the epidemic. This study reports findings of a content analysis of AIDS coverage of government owned newspapers in Senegal, ...

Several documents have been published offering guidelines for implementing AIDS education. These documents generally cite the need for AIDS education, and identify issues and concerns inherent in planning AIDS education. Though such guidelines are beneficial in establishing the legitimate need for AIDS education, the information provided does not address the ...

The nation's response to AIDS has failed to effectively curb the spread of AIDS among intravenous (IV) drug users, who are primarily responsible for transmitting the disease to heterosexuals and children. A study assessing awareness of AIDS among 58 county jail inmates--27 IV drug abusers and 31 nonintravenous drug abusers--found ...

A scarcity of knowledge exists regarding the sexual behavior of intravenous drug abusers (IVDAs) despite their potential role in the heterosexual transmission of acquired immunodeficiency syndrome (AIDS). Using a standardized questionnaire of drug and sexual practices, 96 patients enrolled in methadone maintenance treatment in New York City were interviewed anonymously.Over ...
