This study, carried out in 13 sheep flocks of central-western Mexico, aimed to identify the prevalence of anti-N. caninum antibodies, to develop a risk analysis of the infection and to estimate the prevalence of parasite DNA in blood. A total of 368 serum and blood samples were subjected to ELISA and PCR tests, respectively, and the association between the prevalence of antibodies and some management factors was estimated. The overall prevalence of anti-N. caninum antibodies was 13.5% [50/368; 95% confidence interval (CI) 10–17], ranging from 2.7 to 90% per flock, and 92% of the farms had seropositive animals. In ewes the prevalence was 14% (48/348, 95% CI 10–17) and in rams 10% (2/20; 95% CI 1– 33). The mean prevalence of Neospora DNA in blood was 27% (99/368, 95% CI 22–31), implying a range between 16 and 82%. In rams, the prevalence was 5% (1/20 95% CI 2–26), while in ewes it was 28% (98/348, 95% CI 23–33). The agreement between the tests was k = 0.19. The presence of other domestic animal species in the farms [odds ratio (OR) 4.4] and the consumption of placental debris, fetuses and stillborn lambs by dogs living in the farms (OR 5.8) were demonstrated to be risk factors.

Abstract The aims of this survey were to determine the frequency of anti-Toxoplasma gondii and anti-Neospora caninum antibodies and to identify the risk factors associated with seropositivity among buffaloes in the state of Paraíba, Brazil. This survey included 136 buffaloes belonging to 14 herds. To detect anti-T. gondii and anti-N. caninum antibodies, the indirect fluorescent antibody test (IFAT) was used. Among the 136 samples analyzed, 17 (12.5%) were positive for anti-T. gondii antibodies with titers ranging from 64 to 1,024, and 26 (19.1%) for anti-N. caninum with titers from 200 to 1,600. Animals seropositive for both T. gondii and N. caninum were found in 10 of the 14 herds (71.4%). Semi-intensive management systems (odds ratio = 2.99) and presence of pigs (odds ratio = 4.33) were identified as risk factors for T. gondii and N. caninum, respectively. It can be suggested that T. gondii and N. caninum are widespread in buffaloes in Paraíba, and that additional surveys are needed in order to ascertain the importance of these agents for this species and for pigs, and the influence of the farming type on occurrences of seropositive animals.

Postnatal Transmission

Aborting and nonaborting cows and their dams or daughters were studied to determine if herd abortion problems were associated with the presence of Neospora caninum antibodies and to estimate when aborting cows may have acquired the infection. Cows were sampled from 20 herds that had experienced an abortion epidemic presumed to have been caused by N. caninum and from 2 herds experiencing endemic abortion. Seroprevalence for 14 herds experiencing an epidemic ranged from 7% to 70%, as estimated by enzyme-linked immunosorbent assay. A strong association between seropositivity and abortion was found for only 5 of 14 herds with a presumed diagnosis of N. caninum abortion ( P ≤ 0.015, lower 95% confidence interval of odds ratio ≥ 1.2), indicating N. caninum may be overdiagnosed as the cause of an abortion epidemic in some herds. No association was found between dam and daughter seropositivity for herds experiencing an epidemic ( P ≥ 0.17), suggesting that most cows aborting during an epidemic were infected postnatally. For the 2 herds with endemic abortion (A, B), odds of an aborting cow having N. caninum antibodies were 3.4-fold (herd A) and 7.0-fold (herd B) higher than odds for nonaborting cows ( P ≤ 0.05). Cows that aborted a fetus infected with N. caninum were more likely to have had a previous seropositive daughter than were nonaborting seronegative cows ( P ≤ 0.0025), suggesting that infection had been acquired before conception of the aborted fetus.

Método: Esse é um estudo epidemiológico transversal com a aplicação de questionário para 115 trabalhadores de um total de 129 funcionários. O questionário incluiu a caracterização sóciodemográfica, situação do trabalho e satisfação no trabalho e é baseado no questionário de Cooper´s (Occupational Stress Indicator-OSI). A análise dos dados incluiu a análise de regressão para verificação dos fatores de risco associados à insatisfação, sendo esta definida quando o total de pontos for menor ou igual a 76. Resultado: A maioria dos trabalhadores eram mulheres (81%), com nível educacional secundário (58%), casados (50%) com filhos (61%) e trabalhavam como atendentes de nutrição (66%). A média de idade era de 37 anos com o tempo de trabalho no hospital de 9 anos. A prevalência de insatisfação no trabalho foi de 59%. Os fatores de risco associados a satisfação no trabalho foram: presença de sintomas osteomusculares (Odds ratio (OR) 5,68, 95 % CI, 1.96-16.44); volume de trabalho excessivo (OR 3.91, 95% CI, 1.36-11.23); trabalho monótono e repetitivo (OR 3.60, 95% CI, 1.35-9.57) e pobre qualidade de instrumentos de trabalho (OR 3.47, 95% CI, 1.26-9.54). Discussão: A associação entre insatisfação no trabalho e presença de sintomas osteomusculares sugere a possibilidade da contribuição da insatisfação na presença da sintomatologia bem como o inverso, considerando tratar-se de estudo transversal. As ações preventivas deveriam incluir mudanças na organização do trabalho e melhora na qualidade dos instrumentos.</p></span></span>

Neospora Caninum

A toxoplasmose e neosporose são doenças que podem afetar os animais de produção causando perdas econômicas significativas. Sabendo disso, foram determinados os fatores de risco e a ocorrência de anticorpos anti-Toxoplasma gondii e anti-Neospora caninum em 81 ovinos de sete propriedades da região de Guarapuava, Paraná, Brasil. A pesquisa de anticorpos foi realizada por meio da Reação de Imunofluorêscencia Indireta (RIFI) e foi observada uma frequência de 40,74% para T. gondii e de 3,70% para N. caninum. Os fatores de risco pressupostos para ambas as infecções foram: o contato direto dos ovinos com felinos, para T. gondii, e com cães para N. caninum, presença de aborto no rebanho e o acesso de outras espécies animais ao mesmo bebedouro dos ovinos. Por meio do Teste Exato de Fisher foram calculados o IC (95%), Odds ratio e o valor de p, os quais não revelaram associação entre a ocorrência de anticorpos e os fatores de riscos analisados. Pode-se afirmar que os protozoários T. gondii e N. caninum estão presentes entre os rebanhos de ovinos dessa região.

Strengths And Difficulties

Zusammenfassung. ADHS ist durch die Kernsymptome Unaufmerksamkeit, motorische Unruhe und Impulsivität gekennzeichnet. Die Diagnostik der ADHS ist aufwändig und kann nur klinisch erfolgen. Anhand der Verlaufsdaten aus zwei Erhebungszeitpunkten der KiGGS-Studie wird hier untersucht, (a) wie häufig Eltern eine für ihre zum Ersterhebungszeitpunkt (t0, 2003–2006) drei bis 11 Jahre alten Kinder berichtete ADHS-Lebenszeitprävalenz zum zweiten Erhebungszeitpunkt (t1, 2009–2012) erneut berichten und (b) wie häufig eine jemals durch einen Arzt oder Psychologen gestellte ADHS-Diagnose in einem Zeitraum von sechs Jahren erstmalig berichtet wird (Diagnose-Inzidenz). Dazu wurden ausgewählte kind- und umfeldbezogene Einflussfaktoren wie Geschlecht, Transition in eine andere Lebensphase, Rauchen und Alkoholkonsum der Mutter während der Schwangerschaft und Stillzeit, Familienstruktur und Sozialstatus sowie die psychopathologische Symptombelastung gemäß Strengths and Difficulties Questionnaire (SDQ) zu beiden Messzeitpunkten longitudinal untersucht. Im Ergebnis berichteten 57.4% der Eltern, die zum Ersterhebungszeitpunkt eine jemals gestellte ADHS-Diagnose berichtet hatten, diese nach sechs Jahren erneut. Multivariat betrug das Odds Ratio für einen stabilen Elternbericht der ADHS-Lebenszeitprävalenz für Jungen OR = 5.04, für Rauchen der Mutter in der Schwangerschaft OR = 2.84 für Peerprobleme OR = 1.30 und für Hyperaktivitätsprobleme OR = 1.21 zu t0. Die Diagnose-Inzidenz lag insgesamt bei 3.6%. Die Inzidenz war für Jungen dreimal so hoch wie für Mädchen und nahm mit steigendem Alter ab. Alle Prädiktoren mit Ausnahme des Alkoholkonsums der Mutter in der Schwangerschaft waren bivariat mit der Diagnose-Inzidenz signifikant assoziiert. Multivariat erwiesen sich jedoch nur männliches Geschlecht (OR = 2.89), die Transition in die Adoleszenz (OR = 0.38) sowie Verhaltens- (OR = 1.15) und Peerprobleme (OR = 1.46) zu t0 als signifikante Prädiktoren.

Statistische Auswertung

ZusammenfassungStürze sind die häufigste Frakturursache. Eine effiziente Diagnostik von sturzund frakturgefährdeten Patienten unter Praxisbedingungen ist von hoher Bedeutung.Es wurden die im DVO-Osteoporoseregister dokumentierten Daten von 10 804 Frauen bezüglich der Ergebnisse von Chair-Rising-Test, “Up and go”-Test und Tandemstand ausgewertet. Für 633 Frauen lag auch das Ergebnis einer Handkraftmessung vor. Die statistische Auswertung erfolgte zum einen über die Anwendung des Chi-Quadrat- Tests mit Hilfe von Kreuztabellen, zum anderen durch die Bestimmung der Odds Ratio.Bei einem auffälligen Testergebnis ist die Wahrscheinlichkeit, dass prävalente und/oder inzidente Frakturen vorhanden sind, bei Frauen signifikant erhöht. So beträgt die Odds Ratio beim Chair-Rising- Test 1,975, beim Tandemstand 2,3938 und beim “Up an go”-Test 2,0382. Bei Frauen, bei denen eine auffällige Handkraftmessung beobachtet wurde, zeigt sich, dass weder beim Chair- Rising-Test (p = 0,8706) noch beim „Up and go”-Test (p = 0,0526) eine Abhängigkeit zwischen einem auffälligen Test - ergebnis und vorhandenen Frakturen besteht. Der Tandemstand jedoch signalisiert bezüglich eines Zusammenhangs zwischen einem auffälligen Testergebnis und vorhandenen Frakturen eine hochsignifikante Abhängigkeit (p < 0,001). Die Wahrscheinlichkeit, dass eine Fraktur bei einem auffälligen Testergebnis des Tandemstands vorhanden ist, ist um den Faktor 6,2585 erhöht.Die Testung des Tandemstands in Verbindung mit einer Handkraftmessung hat einen hohen Aussagewert für die Ermittlung des Sturz- und Frakturrisikos bei älteren Frauen. Frauen mit einem negativen Ergebnis bei der Testung des Chair-Rising- oder des „Up and go”-Manövers hatten ebenfalls signifikant mehr Frakturen als Frauen mit normalem Testergebnis.
