Ageing in the Caribbean and the human rights of older persons: Twin imperatives for action

This study addresses the ageing of the Caribbean population and the situation with respect to the human rights of older persons. It considers the implications for public policy of these ‘twin imperatives for action’. The first chapter describes and explains the changing age structure of the Caribbean population. Important features of the ageing dynamic, such as differential regional and national trends and the growing number of ‘older old’ persons, are also analysed. The study then describes the progress that has been made in advancing and clarifying the human rights of older persons in international law. The core of the study then consists of an assessment of the current situation of older persons in the Caribbean and the extent to which their human rights are realised in practice. The thematic areas of economic security, health, and enabling environments – which roughly correspond to the three priority areas of the Madrid International Plan of Action on Ageing – are each addressed in individual chapters. These chapters evaluate national policies and programmes for older persons and make public policy recommendations intended to protect and fulfil the human rights of older persons. The report concludes by summarising the priorities for future action both through the establishment of new international human rights instruments as well as national policies and programmes.

G81-562 Guidelines for Using Pipewick and Other Selective Applicators

The use of selective applicators is being rapidly adopted by farmers to supplement their weed control programs. A low-cost method of removing tall, escaped weeds from short stature crops, selective application is also environmentally appealing since the herbicide is applied only to the target weeds and thus only small amounts of herbicides are used. There are three basic types of applicators available: ropewicks, recirculating sprayers (RCS), and carpeted rollers. This NebGuide discusses each applicator and how it can be used on the farm.

The relationship between social support and functional capacity in elderly persons with cognitive alterations

The objective of this study was to identify the relationship between social support and the functional capacity of elderly persons with cognitive alterations. It is a descriptive, cross-sectional and quantitative study. The subjects were 101 elderly persons registered in Family Health Centers whose performance in the Mini-Exam for Mental Status was below a certain specified level in a previous study. The Medical Outcomes Study questionnaire, Katz Index and Pfeffer Questionnaire were applied. The dimensions of material, affective, emotional, informational and positive social interaction support resulted in an average final score of 74.32 points, indicating a better level of material and affective support in relation to the other dimensions of support. There was a statistically significant correlation between emotional support and the Katz Index. Knowledge about this relationship favors the development of a nursing care pathway for the elderly which is capable of maintaining their functional capacity and ensuring satisfactory social relations.

EVALUATION OF THE PERFORMANCE OF A CASTOR-OIL BASED FORMULATION IN LIMITING PESTICIDE RESIDUES IN STRAWBERRY CROPS

A study was made to evaluate the effect of a castor oil-based detergent on strawberry crops treated with different classes of pesticides, namely deltamethrin, folpet, tebuconazole, abamectin and mancozeb, in a controlled environment. Experimental crops of greenhouse strawberries were cultivated in five different ways with control groups using pesticides and castor oil-based detergent. The results showed that the group 2, which was treated with castor oil-based detergent, presented the lowest amount of pesticide residues and the highest quality of fruit produced.

Assessment of the sublethal toxicity of organochlorine pesticide endosulfan in juvenile common carp (Cyprinus carpio)

This study is aimed at evaluating the sublethal effects of endosulfan (EDS) in juvenile common carp (Cyprinus carpio). For this purpose, fish were exposed for 15 days to the technical EDS (95% pure) diluted in dimethyl sulfoxide (DMSO) 0.1% of the total volume in water solution in a semi-static system at sublethal concentration (1 mu g/L). Subsequently, the liver somatic index (LSI) and factor condition (K) were determined. The total cytocrome P450 (CYP), CYP1A isoform, and the ethoxyresorufin-O-deethylase (EROD) activity were determined from the hepatic microsomal fraction as well as the activity of the oxidative stress enzyme system such as superoxide dismutase (SOD), catalase (CAT), glutathione-S-transferase (GST), glutathione peroxidase (GP(X)), glutathione reductase (GR), and glucose-6-phosphate dehydrogenase (G6PDH). Among the parameters assessed, EDS at the sublethal concentration in subchronic exposure caused significant changes in liver somatic indices as well as induction of the phase I biotransformation system and oxidative stress in juvenile common carp (Cyprinus carpio). Thus, it is seen that the use of biochemical biomarkers of environmental contamination in this study proved to be an extremely important tool for detecting the adverse effects of xenobiotics in the aquatic environment, even at low concentration.

Attitudes of mental health professionals towards persons with schizophrenia: a transcultural comparison between Switzerland and Brazil

Background: Stigmatization is an important issue in the treatment and course of schizophrenia. The maintenance of stigmatizing attitudes may be related to socio-cultural factors. Objectives: To compare stigmatizing attitudes of mental health professionals in the culturally diverse countries Brazil and Switzerland. Methods: We analyzed data of two broad stigmatization surveys from Switzerland and Brazil by focusing on the social distance and attitudes of mental health professionals towards the acceptance of side effects of psychopharmacological treatment. Results: Swiss mental health professionals showed significantly higher levels of social distance than their Brazilian counterparts. There was also a weak effect of age as well as an interaction effect between origin and age. With respect to the acceptance of side effects, the effect of origin was rather weak. With the exception of drug dependence, Swiss professionals' acceptance of long-lasting side effects was significantly higher than for their counterparts in Brazil. Discussion: The strong association between origin and social distance may be related to the socio-cultural background of the mental health professionals. In comparison with Switzerland, Brazil is very heterogeneous in terms of ethnicity and socio-economic structure. The distinct acceptance of side effects may additionally be related to the more sophisticated medicaments (i.e. new generation of antipsychotic drugs) commonly used in Switzerland.

Living Invisible: HTLV-1-Infected Persons and the Lack of Care in Public Health

Introduction: Human T-cell lymphotropic virus type 1 (HTLV-1) infection is intractable and endemic in many countries. Although a few individuals have severe symptoms, most patients remain asymptomatic throughout their lives and their infections may be unknown to many health professionals. HTLV-1 can be considered a neglected public health problem and there are not many studies specifically on patients' needs and emotional experiences. Objective: To better understand how women and men living with HTLV-1 experience the disease and what issues exist in their healthcare processes. Methods: A qualitative study using participant observation and life story interview methods was conducted with 13 symptomatic and asymptomatic patients, at the outpatient clinic of the Emilio Ribas Infectious Diseases Institute, in Sao Paulo, Brazil. Results and Discussion: The interviewees stated that HTLV-1 is a largely unknown infection to society and health professionals. Counseling is rare, but when it occurs, focuses on the low probability of developing HTLV-1 related diseases without adequately addressing the risk of infection transmission or reproductive decisions. The diagnosis of HTLV-1 can remain a stigmatized secret as patients deny their situations. As a consequence, the disease remains invisible and there are potentially negative implications for patient self-care and the identification of infected relatives. This perception seems to be shared by some health professionals who do not appear to understand the importance of preventing new infections. Conclusions: Patients and medical staff referred that the main focus was the illness risk, but not the identification of infected relatives to prevent new infections. This biomedical model of care makes prevention difficult, contributes to the lack of care in public health for HTLV-1, and further perpetuates the infection among populations. Thus, HTLV-1 patients experience an "invisibility" of their complex demands and feel that their rights as citizens are ignored.
