School injury and gender differentials: a prospective cohort study

This study assessed the role of certain individual characteristics in school injury among male and female adolescents. The sample included 2,398 subjects attending middle schools and high schools. Respondents completed a self-administered questionnaire at the beginning of the school year. School nurse completed a questionnaire on injury for each school injury occurred during the school year. The data was analyzed with the adjusted odds ratios (ORa) computed via the logistic models. The school injury was common (13% for both sexes). Sports/physical training injury was more frequent among girls (8.8% vs. 6.6%, P < 0.05) contrarily to the other types of injury (4.6% vs. 8.8%, P = 0.001). Sports/physical training injury was strongly associated with age <15 years (ORa 3.42) and presence of previous injury (2.63) among boys, and with age <15 years (2.02), presence of previous injury (2.94), not easily irritated (1.89), and irresponsible (1.59) among girls. The other types of injury were highly related to age <15 years (ORa 4.18), frequent use of psychotropic drugs (1.76), not living with both parents (1.65), being not calm (2.03), and presence of previous injury (1.82) among boys, and to age <15 years (2.59), obesity (3.24), and being not calm (1.84) among girls. The present study identified a number of potential risk factors for school injury among male and female adolescents. Preventive measures should be taken to make adolescents, their parents and teachers more aware of the risks and to find remedial measures.

High Rate of Simian Immunodeficiency Virus (SIV) Infections in Wild Chimpanzees in Northeastern Gabon

The emergence of HIV-1 groups M, N, O, and P is the result of four independent cross-species transmissions between chimpanzees (cpz) and gorillas (gor) from central/south Cameroon and humans respectively. Although the first two SIVcpz were identified in wild-born captive chimpanzees in Gabon in 1989, no study has been conducted so far in wild chimpanzees in Gabon. To document the SIVcpz infection rate, genetic diversity, and routes of virus transmission, we analyzed 1458 faecal samples collected in 16 different locations across the country, and we conducted follow-up missions in two of them. We found 380 SIV antibody positive samples in 6 different locations in the north and northeast. We determined the number of individuals collected by microsatellite analysis and obtained an adjusted SIV prevalence of 39.45%. We performed parental analysis to investigate viral spread between and within communities and found that SIVs were epidemiologically linked and were transmitted by both horizontal and vertical routes. We amplified pol and gp41 fragments and obtained 57 new SIVcpzPtt strains from three sites. All strains, but one, clustered together within a specific phylogeographic clade. Given that these SIV positive samples have been collected nearby villages and that humans continue to encroach in ape’s territories, the emergence of a new HIV in this area needs to be considered.     

Metazoan parasite communities of catfishes (Teleostei: Siluridae) in Benin (West Africa)

The need for more precise information on the effect of dry season on fish parasite communities in Benin lead us to undergo a focus during this season in one of the major sites of collection fry by fish farmers.Metazoan parasites were then inventoried in 166 specimens of catfishes which constituted of C larias gariepinus, Clarias ebriensis, Synodontis schall, Synodontis nigrita, and Chrysichthys nigrodigitatus (Teleostei: Siluridae). Those fishes were collected from fishermen of Agonlin-Lowé at the side of Oueme River in south Benin from November 2011 to March 2012. In total, 12 parasite species were listed comprising three Monogena (Gyrodactylus sp., Synodontella sp., and Protoancylodiscoides chrysichthes), three Cestoda (Stoeksia pujehuni, Lytocestus sp., and Cestode indeterminate), five Nematoda (Paracamallanus cyathopharynx, Procamallanus laevionchus, Cithariniella petterae, Synodontisia thelastomoides, and nematode indeterminate), and one indeterminated Copepod species. Total infestation rate varied between 83.87 and 100 % for the different fish species. This was high but independent of fish sex (χ ²?=?1.669, df?=?4, nonsignificant). The highest mean intensity and mean abundance were, respectively, 44 and 13.33. Monogenea and Nematoda have elevated frequency of dominance, and their presence in the host is significantly correlated (r?=??0.999; p?P. laevionchus and Proteoancylodiscoides, respectively, in C. gariepinus and in C. nigrodigitatus, the parasites showed clumped distribution. The component community diversity, as measured by the Shannon index (H′), revealed that S. schall had the most parasite diversity.
