Detection of viral diseases in shrimp Litopenaeus vannamei in Iran with emphasis on white spot disease prevention by using marine alga extract

Nowadays, following was expanded shrimp breeding and culture; viral diseases have been main problem which threatened shrimp industry in the country. Therefore, shrimp samples were obtained from different stages of Litopenaeus vannmei life cycle (larval, post larval, juveniles, adults and broodstocks) based on clinical signs in the breeding center and shrimp farming from Bushehr, Khozestan and Sistan and Baluchestan provinces. Viral diseases were detected by PCR (Polymerase Chain Reaction), histopathology and transmission electron microscopy (TEM) methods. Results of the PCR were indicated present white spot virus (WSV) in juveniles, sub adults and adults shrimp with medium intensity from three provinces, but it was not showed in larval and post larval stages. Histopathological sections were indicated hypertrophy and basophilic Cowdry type A formation in nucleus cells of gill, haematopoietic, lymphoid and epithelial's cuticles and intestinal tissues which was associated with small vacuoles increased in B cells of hepatopancreas tissue of infection shrimps. Transmission electronic microscopic studies were demonstrated that the length and diameter virus was detected, respectively, 300 ± 20 nm and 75 ± 5 nm. Considerable, results of the PCR were only displayed IHHNV in juvenile, adult and broodstock shrimps from breeding and farming center of Bushehr province. The main lesion pathology was formed eosinophilic Cowdry type A in nucleus cells of gill, haematopoietic, lymphoid and epithelial's cuticles and intestinal tissues. Whereas penaeid shrimps are lack specific immune system, hence, in the present study was used of marine alga (Lurensia snideria) collected from along costal Persian Gulf of Bushehr province for viral diseases were prevented. Powder alga extract were added with a ratio of 1 % to shrimp diet. Total haemocyte count (THC) and total protein plasma (TPP) were increased after 5 days of oral administration diets. When shrimps were infected by with spot virus experimentally, THC and TPP gradually were increased in both two groups (shrimps fed with diet containing alga extract and without alga extract) after 48h. Nevertheless; THC, TPP and survival of shrimp fed with diet containing alga extract were more than shrimp control in 15 days. So, oral administration Lurensia snideria extract was capable prevention infected L. vannamei via stimulant specific immune system.

Spatial and Functional Organization of Pig Trade in Different European Production Systems: Implications for Disease Prevention and Control

Understanding the complexity of live pig trade organization is a key factor to predict and control major infectious diseases, such as classical swine fever (CSF) or African swine fever (ASF). Whereas the organization of pig trade has been described in several European countries with indoor commercial production systems, little information is available on this organization in other systems, such as outdoor or small-scale systems. The objective of this study was to describe and compare the spatial and functional organization of live pig trade in different European countries and different production systems. Data on premise characteristics and pig movements between premises were collected during 2011 from Bulgaria, France, Italy, and Spain, which swine industry is representative of most of the production systems in Europe (i.e., commercial vs. small-scale and outdoor vs. indoor). Trade communities were identified in each country using the Walktrap algorithm. Several descriptive and network metrics were generated at country and community levels. Pig trade organization showed heterogeneous spatial and functional organization. Trade communities mostly composed of indoor commercial premises were identified in western France, northern Italy, northern Spain, and north-western Bulgaria. They covered large distances, overlapped in space, demonstrated both scale-free and small-world properties, with a role of trade operators and multipliers as key premises. Trade communities involving outdoor commercial premises were identified in western Spain, south-western and central France. They were more spatially clustered, demonstrated scale-free properties, with multipliers as key premises. Small-scale communities involved the majority of premises in Bulgaria and in central and Southern Italy. They were spatially clustered and had scale-free properties, with key premises usually being commercial production premises. These results indicate that a disease might spread very differently according to the production system and that key premises could be targeted to more cost-effectively control diseases. This study provides useful epidemiological information and parameters that could be used to design risk-based surveillance strategies or to more accurately model the risk of introduction or spread of devastating swine diseases, such as ASF, CSF, or foot-and-mouth disease.

Knowledge as a factor in vulnerability to tuberculosis among nursing students and professionals

The objective of this study was to identify vulnerability to tuberculosis (TB) related to knowledge about the disease among 76 nursing students and professionals. A quantitative descriptive study was conducted using a closed questionnaire for the collection of data regarding transmission, preventive and biosafety measures, diagnosis, and prejudice regarding the disease. The SAS software version 9.1.3 was used for data analysis, with the level of significance set at 5% (p < 0.05). Nursing students and professionals showed a vulnerability to TB related to knowledge about transmission, preventive and biosafety measures, and diagnosis of the disease. With respect to transmission, vulnerability was higher among nursing professionals. The results indicate the need for investment by healthcare institutions surrounding this topic in view of the important role of nursing in the establishment of strategies for prevention and control of the disease.

SBD-RESP na busca ativa de casos de hanseníase

FUNDAMENTOS: A Sociedade Brasileira de Dermatologia Regional do Estado de São Paulo (SBD-RESP), apoiada pela Fundação Paulista Contra a Hanseníase, e em ação conjunta com os Serviços de Dermatologia do estado de São Paulo, credenciados pela Sociedade Brasileira de Dermatologia, lançou a campanha SBD-RESP na Busca Ativa de Casos de Hanseníase. OBJETIVOS: Auxiliar o Programa Nacional de Controle da Hanseníase no controle da doença. MÉTODO: Todos os Serviços de Dermatologia do estado de São Paulo, credenciados pela Sociedade Brasileira de Dermatologia, foram convidados e os 17 que participaram receberam uma planilha de dados e modelos de materiais informativos sobre a doença. A campanha foi realizada entre os meses de maio e julho de 2010. Ao término do período, cada serviço encaminhou a planilha de dados para análise estatística. RESULTADOS: Foram examinadas 1718 pessoas e diagnosticados, no total, 90 casos de hanseníase, a maioria do gênero masculino e da cor branca, com percentuais semelhantes de multibacilares e de paucibacilares. Doze por cento apresentavam história familiar de hanseníase. O maior número de casos detectados foi na capital, seguido, no interior, pela região de Presidente Prudente. O índice de detecção em menores de 15 anos foi 4%. CONCLUSÕES: Os resultados da campanha mostram a importância desta iniciativa da SBD-RESP. Sugere-se que ações semelhantes sejam repetidas e que se estendam a outras regionais da Sociedade Brasileira de Dermatologia

Leprosy: a review of laboratory and therapeutic aspects - Part 2

Leprosy is a chronic infectious condition caused by Mycobacterium leprae(M. leprae). It is endemic in many regions of the world and a public health problem in Brazil. Additionally, it presents a wide spectrum of clinical manifestations, which are dependent on the interaction between M. leprae and host, and are related to the degree of immunity to the bacillus. The diagnosis of this disease is a clinical one. However, in some situations laboratory exams are necessary to confirm the diagnosis of leprosy or classify its clinical form. This article aims to update dermatologists on leprosy, through a review of complementary laboratory techniques that can be employed for the diagnosis of leprosy, including Mitsuda intradermal reaction, skin smear microscopy, histopathology, serology, immunohistochemistry, polymerase chain reaction, imaging tests, electromyography, and blood tests. It also aims to explain standard multidrug therapy regimens, the treatment of reactions and resistant cases, immunotherapy with bacillus Calmette-Guérin (BCG) vaccine and chemoprophylaxis.

A Kilkenny Post-primary School Survey: A Survey of Knowledge, Attitudes and Behaviour Relevant to Noncommunicable Disease

The Kilkenny post-primary school survey was carried out in the spring of 1987 on a stratified random sample of 445 post-primary school children in county Kilkenny. The study was designed as the basis for evaluation of the Kilkenny Health Project's school health education programme. The study examined knowledge, attitudes and behaviour relevant to non-communicable disease. The results showed that levels of adolescent alcohol and tobacco use were similar to those found in neighbouring countries. Smoking and drinking increased during adolescence and were more prevalent in males. Physical activity decreased throughout adolescence and a high intake of 'snack' foods was found. Health related knowledge levels were high but were not related to behaviour; however attitudes were found to be consistent with behaviour. These and other results are discussed. Literature relevant to school health education and the aetiology of non-communicable disease is described, with particular reference to Ireland. The evidence supporting health promotion intervention programmes against non-communicable disease is examined and WHO and Irish policies on health promotion outlined. The importance of health and disease prevention programmes commencing in youth is emphasised and the suitability and efficacy of school health education programmes are noted. A number of school health education programmes world-wide are described. The role of the community physician in relation to such programmes is discussed. Finally recommendations are made and areas for further research are made.This resource was contributed by The National Documentation Centre on Drug Use.

HIV & AIDS education and prevention plan 2008-2012. Mid-term review.

In 2008 a 4-year plan for HIV and AIDS Education and Prevention in Ireland was published. The plan aimed to contribute to a reduction in new infections of HIV and AIDS through education and prevention measures. It also aimed to guide and inform the development of policy and services in the statutory and non-statutory sectors with responsibility in this regard. This report is produced as a response to a letter from the Secretariat of the National AIDS Strategy Committee (NASC). The letter requested “feedback from the Education and Prevention Sub-Committee on prevention activities currently in place and on progress to date on the Education and Prevention Action Plan (2008-2012).” In addition, action 2 under Action Area 5: Monitoring and evaluation states that “a mid-term review of the implementation of this action plan should be published”. We note from the HPSC data that there has been a slight decrease in the overall number of new HIV infections however; there has been a huge concern over the large increase in new diagnoses in men who have sex with men (MSM). Although we cannot provide the evidence for the reason for this increase, it is stipulated that there has been a huge increase in the education and prevention programmes targeted at MSM and the report will show the evidence of that increase (Action Area 3: Preventing new infections: population group MSM). There is a presumption that because of increased awareness, access and confidence of MSM and improved treatment that there are more MSM being tested and more diagnoses. This report presents an update on the progress of the implementation of the actions in the HIV and AIDS Education and Prevention Plan 2008-2012.This resource was contributed by The National Documentation Centre on Drug Use.

Community cluster of meningococcal disease by Neisseria meningitidis serogroup C in Andalusia, Spain, March to May 2011.

Between March and May of 2011, a cluster of three fatal cases of meningococcal sepsis occurred in Andalusia, Spain, in a municipality with a population of around 20,000 inhabitants. The cases were in their mid-teens to early thirties and were notified to the epidemiological surveillance system of Andalusia (Sistema de Vigilancia Epidemiológica de Andalucía, SVEA) during a 68-day period from March through May 2011. All three were infected with the same strain of Neisseria meningitidis serogroup C genosubtype VR1:5-1;VR2:10-8. None of the cases had been previously vaccinated against N. meningitidis serogroup C. Antibiotic post-exposure chemoprophylaxis was administered to close contacts of every diagnosed case. Once the cluster was confirmed, the local population was informed through the media about the control measures taken by the health authorities. The vaccination history against N. meningitidis serogroup C of the population under 25 years-old in the municipality was checked. Vaccination was offered to unimmunised individuals younger than 25 years of age and an additional dose of vaccine was offered to those who had been vaccinated between 2000 and 2006 with a vaccination schedule of three doses before the first year of age. No further cases occurred since the beginning of these actions.

Addressing non-communicable diseases in the Seychelles: towards a comprehensive plan of action.

This article reviews the different steps taken during the past 20 years for the prevention and control of non-communicable diseases (NCDs) in the Seychelles. National surveys revealed high levels of several cardiovascular risk factors and prompted an organized response, starting with the creation of an NCD unit in the Ministry of Health. Information campaigns and nationwide activities raised awareness and rallied increasingly broad and high-level support. Significant policy was developed including comprehensive tobacco legislation and a School Nutrition Policy that bans soft drinks in schools. NCD guidelines were developed and specialized 'NCD nurses' were trained to complement doctors in district health centers. Decreasing smoking prevalence is evidence of success, but the raising so-called diabesity epidemic calls for an integrated multi-sector policy to mould an environment conducive to healthy behaviors. Essential components of these efforts include: effective surveillance mechanisms supplemented by focused research; generating broad interest and consensus; mobilizing leadership and commitment at all levels; involving local and international expertise; building on existing efforts; and seeking integrated, multi-disciplinary and multi-sector approaches.

Prévention des infections chez les voyageurs immunosupprimés [Prevention of infection in immunocompromised travelers].

Every year there are more immunocompromised patients with a better quality of life and, therefore, that travel more frequently. While traveling, patients may be exposed to several infections, such as traveler's diarrhea or malaria, which can be associated with a high rate of complications in this population. An appropriate strategy for the prevention of travel-related infections is essential, including education about hygiene measures, vaccinations and prescription of a tailored antimicrobial prophylaxis/stand-by treatment, according to the type of immunosuppression. Potential drug interactions, particularly between antimalaric and immunosuppressive drugs, must also be considered for decision taking. Collaboration between the general practitioner and the travel medicine and infectious diseases specialists is highly recommended to improve the management of these patients.

Drugs and lifestyle for the treatment and prevention of coronary artery disease: comparative analysis of the scientific basis

In this article, we compare two strategies for atherosclerosis treatment: drugs and healthy lifestyle. Statins are the principal drugs used for the treatment of atherosclerosis. Several secondary prevention studies have demonstrated that statins can significantly reduce cardiovascular events including coronary death, the need for surgical revascularization, stroke, total mortality, as well as fatal and non-fatal myocardial infarction. These results were observed in both men and women, the elderly, smokers and non-smokers, diabetics and hypertensives. Primary prevention studies yielded similar results, although total mortality was not affected. Statins also induce atheroma regression and do not cause cancer. However, many unresolved issues remain, such as partial risk reduction, costs, several potential side effects, and long-term use by young patients. Statins act mainly as lipid-lowering drugs but pleiotropic actions are also present. Healthy lifestyle, on the other hand, is effective and inexpensive and has no harmful effects. Five items are associated with lower cardiac risk: non-smoking, BMI ≤25, regular exercise (30 min/day), healthy diet (fruits, vegetables, low-saturated fat, and 5-30 g alcohol/day). Nevertheless, there are difficulties in implementing these measures both at the individual and population levels. Changes in behavior require multidisciplinary care, including medical, nutritional, and psychological counseling. Participation of the entire society is required for such implementation, i.e., universities, schools, media, government, and medical societies. Although these efforts represent a major challenge, such a task must be faced in order to halt the atherosclerosis epidemic that threatens the world.
