Pensionärsjävlar : revolt mot eller ett upprepande av negativa ålderskoder?

Old bastard – rebellion against or a repetition of negative age codes? In contemporary media and scientific contexts, it has become increasingly popular to launch today’s elderly as different from previous generations of older people, especially emphasized is that today’s elderly will have more attitude and set higher demands on society. The TV-series Pensionärsjävlar is based on this idea of today’s and tomorrow’s elderly as different and more rebellious than previous generations. The purpose of this article is to analyze and discuss how age and age codes are used as a prerequisite for, but also are challenged in the series. The result shows that chronological age is almost absent in the series, instead age coding is performed by physical attributes and verbal acts. Most common attributes are those connected to decreased functionality, such as walker, wheelchair, walking stick etcetera. The most common taboo joked about is sexuality, and other common themes are decreased functionality,child/youth- like behavior and traffic. In the article I discuss how these themes and attributes are negotiated in relation to age.  

Summativ bedömning och dess positiva respektive negativa inverkan på elevers lärande

Summativ bedömning har använts inom den svenska skolan under århundraden. Trots detta har denna typ av bedömning passerat relativt obemärkt genom åren. Under de senaste decennierna, när bedömning i högre grad uppmärksammats har den summativa bedömningens konsekvenser på lärandet ifrågasatts. I denna litteraturstudie sammanställs relevant forskning inom området för att tydliggöra den summativa bedömningens positiva och negativa effekter på elevers lärande. Studien redogör för de få positiva effekterna den summativa bedömningen har när den används i formativt syfte. Det redogörs också för de negativa effekter som den summativa bedömningen har för enskilda elevers lärande. Studien visar att det sätt som summativ bedömning traditionellt sett används i skolan är förödande för framför allt lågpresterande elevers motivation och ger dem bristfällig information om vidare lärande. Utifrån detta resultat diskuteras också i denna studie skolans lärandeuppdrag och dess krav på en likvärdig utbildning.

Alimentos e a responsabilidade civil da genitora em decorrência da negativa de paternidade

O presente trabalho teve como ponto de partida o estudo dos alimentos e da obrigação alimentar. Em seguida, realizou-se um breve estudo sobre o direito à filiação, o qual é assegurado pelo Código Civil de 2002 nos artigos 1.596 e seguintes; artigo 227, parágrafo 6º da Constituição Federal e algumas leis complementares, tais como o Estatuto da Criança e do Adolescente. Também foi abordado o tema da investigação de paternidade e seu ônus probatório, enfatizando a ação negatória de paternidade, a qual isenta o réu da obrigação alimentar. Por fim, um estudo sucinto da responsabilidade civil da genitora que, sabendo não ser o réu o pai do seu filho, ajuíza ação pleiteando alimentos, bem como o dano e sua relação com os alimentos pagos ao menor hipossuficiente.

Avaliação do potencial de formigas (Hymenoptera: formicidae) como vetores mecânicos de bactérias do gêneroSstaphylococcus no ambiente hospitalar.

In a hospital environment, these bacteria can be spread by insects such as ants, which are characterized by high adaptability to the urban environment. Staphylococcus is a leading cause of hospital infection. In Europe, Latin America, USA and Canada, the group of coagulase negative staphylococci (CoNS) is the second leading cause of these infections, according to SENTRY (antimicrobial surveillance program- EUA). In this study, we investigated the potential of ants (Hymenoptera: Formicidae) as vehicle mechanics of Staphylococcus bacteria in a public hospital, in Natal-RN. The ants were collected, day and night, from June 2007 to may 2008, in the following sectors: hospitals, laundry, kitchen, blood bank. The ants were identified according to the identification key of Bolton, 1997. For the analysis of staphylococci, the ants were incubated in broth Tryptic Soy Broth (TSB) for 24 hours at 35 º C and then incubated on Mannitol Salt Agar. The typical colonies of staphylococci incubated for 24 hours at 35 ° C in Tryptic Soy Agar for the characterization tests (Gram stain, catalase, susceptibility to bacitracin and free coagulase). The identification of CoNS was performed through biochemical tests: susceptibility to novobiocin, growth under anaerobic conditions, presence of urease, the ornithine decarboxylation and acid production from the sugars mannose, maltose, trehalose, mannitol and xylose. The antimicrobial susceptibility examined by disk-diffusion technique. The technique of Polymerase Chain Reaction was used to confirm the presence of mecA gene and the ability to produce biofilm was verified by testing in vitro using polystyrene inert surface, in samples of resistant staphylococci. Among 440 ants, 85 (19.1%) were carrying coagulase-negative staphylococci (CoNS) of the species Staphylococcus saprophyticus (17), Staphylococcus epidermidis (15), Staphylococcus xylosus (13), Staphylococcus hominis hominis (10), Staphylococcus lugdunensis (10), Staphylococcus warneri (6), Staphylococcus cohnii urealyticum (5), Staphylococcus haemolyticus (3), Staphylococcus simulans (3), Staphylococcus cohnii cohnii (2), and Staphylococcus capitis (1). No Staphylococcus aureus was found. Among the isolates, 30.58% showed resistance to erythromycin. Two samples of CoNS (2.35%), obtained from the ant Tapinoma melanocephalum collected in the post-surgical female ward, S. Hominis hominis and S. lugdunensis harbored the mecA gene and were resistant to multiple antibiotics, and the specie S. hominis hominis even showed to be a biofilm producer. This study proves that ants act as carriers of multidrug-resistant coagulase-negative Staphylococci and biofilm producers and points to the risk of the spreading of pathogenic microorganisms by this insect in the hospital environment

Prevalência e susceptibilidade antimicrobiana de Staphylococcusspp. em quadros de saúde e doença periodontal

The aim of this study was determine the prevalence and antimicrobial susceptibility of Staphylococcus spp. from patients with periodontal disease and periodontally healthy, correlate them with factors to host, local environment and traits of the diseases. To this, thirty adults from 19 to 55 years old were selected. They had not periodontal treatment and no antibiotic or antimicrobial was administered during three previous months. From these individuals, sites periodontally healthy, with chronic gingivitis and/or periodontitis were analyzed. Eighteen subgingival dental biofilm samples were collected through sterile paper points being six from each tooth randomly selected, representing conditions mentioned. They were transported to Oral Microbiology laboratory, plated onto Mannitol Salt Agar (MSA) and incubated at 370C in air for 48 h. Staphylococcus spp. were identified by colonial morphology, Gram stain, catalase reaction, susceptibility to bacitracin and coagulase activity. After identification, strains were submitted to the antibiotic susceptibility test with 12 antimicrobials, based on Kirby-Bauer technique. To establish the relation between coagulase-negative Staphylococcus (CSN) presence and their infection levels and host factors, local environment and traits of diseases were used Chi-square, Mann-Whitney and Kruskal-Wallis tests to a confidence level of 95%. 86,7% subjects harbored CSN in 11,7% periodontal sites. These prevalence were 12,1% in healthy sites, 11,7% in chronic gingivitis, 13,5% in slight chronic periodontitis, 6,75% in moderate chronic periodontitis and in sites with advance chronic periodontitis was not isolated CSN, without difference among them (p = 0,672). There was no significant difference to presence and infection levels of CSN as related to host factors, local environm ent and traits of the diseases. Amongst the 74 samples of CSN isolated, the biggest resistance was observed to penicillin (55,4%), erythromycin (32,4%), tetracycline (12,16%) and clindamycin (9,4%). 5,3% of the isolates were resistant to oxacilin and methicillin. No resistance was observed to ciprofloxacin, rifampicin and vancomycin. It was concluded that staphylococci are found in low numbers in healthy or sick periodontal sites in a similar ratio. However, a trend was observed to a reduction in staphylococci occurrence toward more advanced stages of the disease. This low prevalence was not related to any variables analyzed. Susceptibility profile to antibiotics demonstrates a raised resistance to penicillin and a low one to methicillin. To erythromycin, tetracycline and clindamycin was observed a significant resistance

Tuberculose ativa em pacientes cirúrgicos com baciloscopia negativa no pré-operatório

OBJETIVO: Verificar a proporção de pacientes com baciloscopia negativa no pré-operatório e que apresentaram TB ativa na peça cirúrgica. MÉTODOS: Estudo retrospectivo de pacientes com diagnóstico histopatológico de TB ativa ou sequelar e operados entre os anos de 2003 e 2006 em um hospital universitário. Foram pesquisados antecedentes e aspectos clínicos relativos à doença, pesquisa de bacilos álcool-ácido resistentes (BAAR), tipo de cirurgia realizada e exame histopatológico da peça cirúrgica. RESULTADOS: Foram incluídos 43 pacientes, com média de idade de 44 ± 19 anos, sendo 27 do sexo masculino. Apresentavam história prévia de TB com tratamento adequado 28 pacientes, e 15 não referiam antecedentes para TB. O principal motivo da procura pelo serviço foi infecção de repetição, seguida por achados em exames de imagem. Dos 43 pacientes, foi pesquisado BAAR no pré-operatório em 35: 32 apresentaram resultados negativos e 3, resultados positivos. Dos 35 pacientes pesquisados, 26 apresentavam diagnóstico histopatológico de TB ativa e 9 de TB sequelar na peça cirúrgica; os outros 8 também foram diagnosticados com TB sequelar. A proporção de TB ativa em doentes com baciloscopia negativa foi de 72% (23/32), e o de baciloscopia negativa em TB ativa foi de 88% (23/26), sendo a pesquisa de BAAR positiva somente em 11,5% (3/26). CONCLUSÕES: A baciloscopia direta tem rendimento muito baixo, e muitos pacientes mesmo já tratados podem permanecer com TB em atividade com baciloscopia negativa. A TB ativa pode ser confundida com infecções secundárias ou com câncer.

Occurrence of coagulase-positive Staphylococcus in various food products commercialized in Botucatu, SP, Brazil and detection of toxins from food and isolated strains

The aim of this work was to assess the microbiological quality of commercialized desserts, sandwiches and finger food in Botucatu, SP, for human consumption. A total of 172 food samples were analyzed for fecal coliforms and coagulase-positive Staphylococcus and 69 (40.1%) were in disagreement with the standards established by Decree No. 12 (Brazilian Food Sanitation Standard, 2001). Coagulase-positive Staplylococcus was isolated from 26 (15.1%) samples. Toxins were not isolated directly from foods but 27 (54%) coagulase-positive Staphylococcus strains were enterotoxigenic, and toxin type C was the most frequently detected. These results suggest that these products may act as an important vehicle of transmission for well-established pathogens. (c) 2006 Elsevier Ltd. All rights reserved.

Usefulness of catheter tip culture in the diagnosis of neonatal infections

Objective: To determine the number of colony-forming units (CFU) that best correlates with catheter-related infections (CRI) in newborns.Methods: This was a prospective study of semiquantitative cultures of catheter tips obtained from newborns in the neonatal unit at Faculdade de Medicina de Botucatu, state of São Paulo, Brazil. The microorganisms isolated from catheter and peripheral blood cultures were identified and submitted to a drug susceptibility test. The optimal cutoff point was determined by the receiver operating characteristic (ROC) curve.Results: A total of 85 catheters obtained from 63 newborns were studied. Staphylococcus epidermidis was the predominant species in the catheters (75%). Eight of 11 (72.7%) CRI episodes were associated with coagulase-negative staphylococci, six of which were of the S. epidermidis type. ROC curve analysis indicated that the optimal cutoff point for the diagnosis of CRI was 122 CFU.Conclusions: The cutoff point of 122 CFU correlated best with the diagnosis of CRI in newborns.

Predictive factors of outcome following staphylococcal peritonitis in continuous ambulatory peritoneal dialysis

Background and aims: Staphylococcus epidermidis and other coagulase-negative staphylococci (CoNS) are the most common agents of continuous ambulatory peritoneal dialysis (CAPD) peritonitis. Episodes caused by Staphylococcus aureus evolve with a high method failure rate while CoNS peritonitis is generally benign. The purpose of this study was to compare episodes of peritonitis caused by CoNS species and S. aureus to evaluate the microbiological and host factors that affect outcome. Material and methods: Microbiological and clinical data were retrospectively studied from 86 new episodes of peritonitis caused by staphylococci species between January 1996 and December 2000 in a university dialysis center. The influence of microbiological and host factors (age, sex, diabetes, use of vancomycin, exchange system and treatment time on CAPD) was analyzed by logistic regression model. The clinical outcome was classified into two results (resolution and non-resolution). Results: the odds of peritonitis resolution were not influenced by host factors. Oxacillin susceptibility was present in 30 of 35 S. aureus lineages and 22 of 51 CoNS (p = 0.001). There were 32 of 52 (61.5%) episodes caused by oxacillin-susceptible and 20 of 34 (58.8%) by oxacillin-resistant lineages resolved (p = 0.9713). of the 35 cases caused by S. aureus, 17 (48.6%) resolved and among 51 CoNS episodes 40 (78.4%) resolved. Resolution odds were 7.1 times higher for S. epidermidis than S. aureus (p = 0.0278), while other CoNS had 7.6 times higher odds resolution than S. epidermidis cases (p = 0.052). Episodes caused by S. haemolyticus had similar resolution odds to S. epidermidis (p = 0.859). Conclusions: S. aureus etiology is an independent factor associated with peritonitis non-resolution in CAPD, while S. epidermidis and S. haemolyticus have a lower resolution rate than other CoNS. Possibly the aggressive nature of these agents, particularly S. aureus, can be explained by their recognized pathogenic factors, more than antibiotic resistance.
