Bakgrund: I Sverige ökade prevalensen av rupturer grad IV från 2,6% till 4,2% mellan åren 1994-2004. Årligen är det cirka tretusen kvinnor som drabbas av bristningar av grad III och IV i Sverige. Det är en stor spridning mellan Sveriges olika förlossningsavdelningar.Syfte: Syftet var att beskriva åtgärder för prevention av perinealbristningar av grad III och grad IV vid normal förlossning på samtliga förlossningsavdelningar i Sverige.Metod: Deskriptiv kartläggningsstudie med induktiv ansats. Det är en nationell studie som riktar sig till Sveriges alla förlossningsavdelningar. Endast perinealbristning av grad III och grad IV berördes.Resultat: Totalt deltog 38 av 47 (81%) av Sveriges förlossningsavdelningar i studien. Respondenterna var chefsbarnmorskor, avdelningschefer och enhetschefer. Av deltagande förlossningsavdelningar var det 12 (32%) som har någon form av vårdprogram för perinealskydd, många svarar att barnmorskorna utför perinealskydd på rutin. Dock var det inte vedertaget att alltid hålla perinealskydd vid 8% av avdelningarna. 18 avdelningar svarade JA på frågan om särskilda handgrepp användes och då uppgavs Ritgens handgrepp, det norska handgreppet och det finska handgreppet. 74 % använder sig av även andra metoder än handgrepp, framför allt värme (varma handdukar, dukar, handskar, kompresser) som hålls över perineum. Många tog upp vikten av god kommunikation och att hjälpa kvinnan att krysta i rätt tid. Förlossningsställningar som många använde sig av var sidoläge och knästående, medan andra hävdade att knästående ej användes pågrund av den ökande risken för bristningar. 71% av deltagande avdelningar får kontinuerlig utbildning och då nämndes främst workshops och utbildningsdagar.Slutsats: Metoder för att skydda perineum varierar mellan förlossningsavdelningarna i Sverige. På flera av Sveriges förlossningsavdelningar är det inte vedertaget att alltid använda perinealskydd vid normal förlossning. Vad som orsakar detta tros vara att en del barnmorskor, under utbildningen, fått lära sig att inte hålla perinealskydd.Klinisk implikation: Nationella rikitlinjer angående perinealskydd skulle vara av värde för att kunna erbjuda kvinnan vård på samma villkor landet över. Det är av stor vikt att den förlösande barnmorskan är uppmärksam på riskfaktorerna.

The current system of controlling oil spills involves a complex relationship of international, federal and state law, which has not proven to be very effective. The multiple layers of regulation often leave shipowners unsure of the laws facing them. Furthemore, nations have had difficulty enforcing these legal requirements. This thesis deals with the role marine insurance can play within the existing system of legislation to provide a strong preventative influence that is simple and cost-effective to enforce. In principle, insurance has two ways of enforcing higher safety standards and limiting the risk of an accident occurring. The first is through the use of insurance premiums that are based on the level of care taken by the insured. This means that a person engaging in riskier behavior faces a higher insurance premium, because their actions increase the probability of an accident occurring. The second method, available to the insurer, is collectively known as cancellation provisions or underwriting clauses. These are clauses written into an insurance contract that invalidates the agreement when certain conditions are not met by the insured The problem has been that obtaining information about the behavior of an insured party requires monitoring and that incurs a cost to the insurer. The application of these principles proves to be a more complicated matter. The modern marine insurance industry is a complicated system of multiple contracts, through different insurers, that covers the many facets of oil transportation. Their business practices have resulted in policy packages that cross the neat bounds of individual, specific insurance coverage. This paper shows that insurance can improve safety standards in three general areas -crew training, hull and equipment construction and maintenance, and routing schemes and exclusionary zones. With crew, hull and equipment, underwriting clauses can be used to ensure that minimum standards are met by the insured. Premiums can then be structured to reflect the additional care taken by the insured above and beyond these minimum standards. Routing schemes are traffic flow systems applied to congested waterways, such as the entrance to New York harbor. Using natural obstacles or manmade dividers, ships are separated into two lanes of opposing traffic, similar to a road. Exclusionary zones are marine areas designated off limits to tanker traffic either because of a sensitive ecosystem or because local knowledge is required of the region to ensure safe navigation. Underwriting clauses can be used to nullify an insurance contract when a tanker is not in compliance with established exclusionary zones or routing schemes.

To investigate the role of β-(1-3)-D-glucan on 99mTc labelled Escherichia coli translocation and cytokines secretion in rats submitted to small bowel ischemia/reperfusion injury. Methods: Five groups (n=10 each) of Wistar rats were subjected to control(C), sham(S), group IR subjected to 45 min of bowel ischemia/60 min of reperfusion(I/R), and group I/R+glucan subjected to 45 min of bowel ischemia/60 min of reperfusion(I/R) and injected with 2mg/Kg intramuscular. Translocation of labelled bacteria to mesenteric lymph nodes, liver, spleen, lung and serum was determined using radioactivity/count and colony forming units/g(CFU/g). Serum TNFα, IL-1β, IL-6, IL-10 were measured by ELISA. Results: CFU/g and radioactivity/count were higher in I/R than in I/R+glucan rats. In C, S and S+glucan groups, bacteria and radioactivity/count were rarely detected. The I/R+glucan rats had enhancement of IL-10 and suppressed production of serum TNFα, IL-1β and, IL-6, compared to I/R untreated animals. Conclusion: The β-(1-3)-D-glucan modulated the production of pro-inflammatory and anti-inflammatory cytokines during bowel ischemia/reperfusion, and attenuated translocation of labelled bacteria

The combinations of temperature and time which can cause chilling injuries in avocados 'Geada', 'Quintal' and 'Fortuna' were determined. The binomial 4 degrees C/ 28 days was selected to determine the activity of peroxidase (POD), polyphenoloxidase (PPO), polygalacturonase (PG) and methylesterase pectin (PME). The respiratory activity was also evaluated. The fruits were stored at this condition until being transferred to ambient conditions (22 degrees C and 77% RH) until maturity, when they were compared to fruits stored permanently at this environment, after being cleaned (control). In the second part of this work, different hydrothermal treatments were tested to prevent or minimize chilling injuries. Avocados 'Geada', 'Quintal' and 'Fortuna' were treated at 38 degrees C for 0, 30, 60 and 90 minutes before storage at 4 degrees C for 28 days. It was observed that the activity of enzymes associated to browning, POD and PPO, and to maturation, PG and PME, had become greater in fruits stored at 4 degrees C, or when they were transferred to environmental conditions. Fruits subjected to refrigeration, after transferred to environment, presented lower respiratory peak intensity and it occurred earlier than the others. Treatments using 38 degrees C for 60 and 90 min minimized the symptoms of chilling injury in avocados 'Geada' while for 'Quintal' the most efficient was 38 degrees C for 60 min. In 'Fortuna' these treatments did not minimize the damage by cold.

OBJETIVO: Avaliar o efeito da N-acetilcisteína na proteção renal contra lesão de isquemia/reperfusão, quando administrada logo após a indução anestésica, em ratos anestesiados com isoflurano. MÉTODOS: Dezoito ratos Wistar machos pesando mais que 300g foram anestesiados com isoflurano. A jugular interna direita e a carótida esquerda foram dissecadas e canuladas. Os animais foram distribuídos aleatoriamente em GAcetil, recebendo N-acetilcisteína por via intravenosa, 300mg/kg, e GIsot, solução salina. Foi realizada nefrectomia direita e clampeamento da artéria renal esquerda por 45 min. Os animais foram sacrificados após 48h, sendo colhidas amostras sanguíneas após a indução anestésica e ao sacrifício dos mesmos para avaliar a creatinina sérica. Realizou-se histologia renal. RESULTADOS: A variação da creatinina foi 2,33mg/dL ± 2,21 no GAcetil e 4,38mg/dL ± 2,13 no GIsot (p=0,074). Dois animais apresentaram necrose tubular intensa no GAcetil, comparados a cinco no GIsot. Apenas GAcetil apresentou animais livres de necrose tubular (dois) e degeneração tubular (um). CONCLUSÃO: Após isquemia/reperfusão renais, os ratos aos quais se administrou N-acetilcisteína apresentaram menor variação na creatinina sérica e lesões renais mais leves que o grupo controle.

OBJETIVO: Avaliar o número de podócitos e espessamento da membrana basal glomerular (MBG) em ratos diabéticos com e sem controle glicêmico com 6 e 12 meses da indução. MÉTODOS: 100 ratos Wistar com 200-300g compuseram 6 grupos: Normal (N6, N12 - 25 animais) Diabético (D6,D12 - 25 animais) e diabético tratado com insulina 1,8 a 3,0 U/Kg e acarbose misturada a ração (50g para cada 100g de ração) (DT6 e DT12 - 25 animais). Aloxana foi ministrada via endovenosa na dose de 42mg/Kg. Peso, ingestão hídrica e diurese de 24 horas e glicemia e glicosúria foram determinados antes da inoculação, 7 e 14 dias após e mensalmente. No 14ª dia foi iniciado o tratamento. Três grupos de animais (N6, D6 e DT6) foram sacrificados no 6° mês e três grupos (N12, D12 e DT12), no 12ª mês sendo o tecido renal processado para estudo à microscopia eletrônica. RESULTADOS: A glicemia dos animais DT6 e DT12 diferiram significativamente, dos ratos D6 e D12, e não diferiram dos grupos N6 e N12. O número de podócitos do grupo DT6 não diferiu de N6 e D6 (mediana=11); o número de podócitos de DT12 (mediana=11) diferiu de D12 (mediana=8) e não diferiu de N12 (mediana=11). O espessamento da MBG de D6 (0,18 micrômetros) foi menor que D12 (0,29 micrômetros); de DT6 (0,16 micrômetros) foi menor que D6 (0,18 micrômetros) e de DT12 (0,26 micrômetros) foi menor que D12 (0,29 micrômetros). CONCLUSÃO: O controle da hiperglicemia preveniu o espessamento da MBG na nefropatia diabética aloxânica precoce (6 meses) e tardia (12 meses), e a diminuição do número de podócitos.

Aim: The aim of this paper was to compare the quantity and frequency of alcohol use and its associated negative consequences between two groups of college students who were identified as being risky drinkers. Subjects were randomly allocated in a clinical trial to intervention or control groups. Methods: Risky drinking use was defined as Alcohol Use Disorders Identification Test (AUDIT) >= 8 and/or Rutgers Alcohol Problem Index (RAPI) >= 5 problems in the previous year. Students who had undergone the Brief Alcohol Screening and Intervention for College Students (BASICS) (N = 145 at baseline; 142 at 12 months, and 103 at 24 months, loss of 29.7%) were compared with a control group (N = 121 at baseline; 121 at 12 months and 113 at 24 months, loss of 9.3%), the nonintervention group. Variables included drinking frequency, quantity and peak consumption, dependence assessment, and family and friends' abuse assessment. Results: Treated students at a 24-month follow-up decreased quantity of alcohol use per occasion and lowered AUDIT and RAPI scores. Conclusions: This is the first brief intervention work on risky drinking with college students in Brazil and the results are encouraging. However, it is difficult to conduct individual prevention strategies in a country where culture fosters heavy drinking through poor public policy on alcohol and lack of law enforcement.

According to the World Health Organization (WHO) estimates for the year 2020, approximately 1.5 million people will commit suicide, and at least 10 times that many will make an attempt. This paper offers a brief overview of the current state of the epidemiology of suicide, a burgeoning public health problem. The information provided is based in large measure on reports of suicide mortality from 130/193 countries. In order to contextualize these data, this paper explores the contribution of both individual and sociocultural factors that influence suicidal behavior, from which much has been learned. Outlining the history of attempts by international and national organizations like WHO, United Nations, member states in the European community and other countries to regularize identification and suicide reporting procedures, this paper also demonstrates that serious knowledge gaps remain. Minimal requirements for successful evidence-based interventions are presented. (C) 2010 Published by Elsevier Masson SAS.

Groups of inbred alloxan-induced diabetic rats were treated with insulin (I), islets (IT), or pancreas transplantation (PT). Nondiabetic (N) and untreated diabetic (D) control groups were concurrently included. Each group was divided into five subgroups of 10 rats and killed after follow-up of 1, 3, 6, 9, and 12 months. Clinical and laboratory parameters were recorded, and kidney ultrastructural and morphometric analyses performed in each 12-month subgroup, namely glomerular basement membrane (GM) thickening, podocyte number, and number/extension of slit diaphragms (S). Rats from the I group showed poor metabolic control of diabetes compared with N group control rats. However, successfully transplanted rats (IT and PT) had complete restoration to normal levels for all metabolic parameters. GM thickening was significantly higher in diabetic compared with control rats. In contrast, the numbers of podocytes and slits as well as slit extensions were significantly decreased. Insulin therapy did not prevent any alterations upon comparison of diabetic vs control rats. Despite good metabolic control in IT rats, the degree of kidney lesion control never compared with that achieved in PT rats. In this group all glomerular changes were similar to the age-dependent lesions observed in control rats. We conclude that either IT or PT may be a good option for diabetes treatment, although pancreas transplantation seems to be the most effective treatment to control chronic complications.
