Título: Low seroprevalence of Zika virus in Cameroonian blood donors
Fonte: Braz. j. infect. dis;21(4):481-483, July-Aug. 2017. graf.
Idioma: en.
Projeto: Innovation Program under ZIKAlliance Grant Agreement.
Resumo: Abstract A Zika virus seroepidemiology study was performed in 1084 blood donors collected from August to October 2015 in six sites of Cameroon representing a large panel of eco-environments. Samples were tested using an anti-NS1 IgG ELISA detection kit and positives were further confirmed by seroneutralization. The observed global seroprevalence was low (around 5%, peaking at 10% and 7.7% in Douala and Bertoua, respectively) with risk factors associated with seropositivity pointing to the existence of a local (peri-)sylvatic cycle of transmission. These results call attention to the potential introduction and subsequent spread in African urban areas of Asian genotype Zika virus currently circulating in the Americas and adapted to transmission by peri-domestic mosquitoes. They should leverage reinforced surveillance efforts in Africa.

Título: Maternal mortality in Maroua Provincial Hospital, Cameroon (2003-2005)
Fonte: West Indian med. j;56(6):502-507, Dec. 2007. tab.
Idioma: en.
Resumo: Background: In September 2000, the Heads of States of the 191 countries of the United Nations approved the Millennium Declaration in which reduction of pregnancy-related deaths to a quarter by 2015 was one of its goals. However, before the middle of the first decade of this millennium, there were no reports on the status of maternal mortality in Maroua, Cameroon.Objective: The aim of this study was to establish baseline data on maternal mortality for future evaluation of pregnancy-related mortality trends in this city. Subjects and Methods: Maternal deaths that occurred from 2003 to 2005 in Maroua City, Cameroon,were analyzed. Mortality ratios were determined by comparing the number of the deaths related to pregnancy with that of women with safe deliveries. Mortality risks were determined by comparing the characteristics of women with pregnancy-related deaths to those of women with safe deliveries. Results: The overall maternal mortality ratio was 1266 maternal deaths per 100 000 live births. The leading causes of death were hypertension (17.5%), obstetric infections (14.3%), uterine rupture(14.3%), anaemia (12.7%) and HIV complications (9.5%). Among the women who died, 28.6% were teenagers and 14.3% were at their sixth delivery (or above). Compared with women aged 20 to 24 years, those aged 25 to 29 years were more than twice as likely to die from pregnancy-related causes (HR: 2.34; CI: 1.07,5.08; p = 0.029). A similar trend was also found in those aged 30 to 34 years (HR: 2.26; CI: 1.02,5.00; p = 0.042). Conclusion: The findings suggest that Maternal Mortality Ratio in Maroua, City, Cameroon, is veryhigh. Since most of the causes of death were preventable, we propose that the current maternal and Family Planning strategies be reviewed with the view to reducing the current trend. Such a strategy would enable the Maroua city to meet the Millennium goals by 2015.

Antecedentes: En septiembre del 2000, los Jefes de Estado de 191 países de la Naciones Unidas, aprobaron la Declaración del Milenio, una de cuyas metas es la reducción hasta una cuarta parte, de las muertes relacionadas con el embarazo, para el año 2015. Sin embargo, antes de mediados de la primera década de este milenio, no habia reportes sobre el estado de la mortalidad materna en Maroua, Camerún. Objetivo: El objetivo de este estudio fue establecer los datos preliminares comparativos de referenciasobre la mortalidad materna para la evaluación futura de las tendencias de la mortalidad en relación con el embarazo en esta ciudad. Sujetos y Métodos: Se analizaron las muertes maternas ocurridas del 2003 al 2005 en la ciudad de Maroua, Camerún. Las tasas de mortalidad fueron determinadas comparando el número de muertesrelacionadas con el embarazo, con el número de mujeres que tuvieron partos seguros. Los riesgos de mortalidad fueron determinados comparando las características de mujeres que murieron por causas asociadas al embarazo, con mujeres que tuvieron partos seguros. Resultados: La tasa general de mortalidad materna fue de 1266 muertes maternas por cada 100 000nacidos vivos. Las causas principales de muerte fueron: hipertensión (17.5%), infecciones obstétricas (14.3%), ruptura uterina (14.3%), anemia (12.7%) y complicaciones por VIH (9.5%). De las mujeres que murieron, 28.6% eran adolescentes y 14.3% estaban en su sexto parto (o por encima). En comparación con las mujeres de 20 a 24 años de edad, las de 25 a 29 años presentaban una probabilidad dos veces mayor de morir por causas relacionadas con el embarazo (HR: 2.34; CI: 1.07, 5.08; p =0.029). Una tendencia similar se halló también en las mujeres de 30 a 34 años de edad (HR: 2.26; CI: 1.02, 5.00; p = 0.042). Conclusión: Los hallazgos sugieren que la tasa de mortalidad maternal en la ciudad de Maroua,Camerún, es muy alta...

Título: Field trials of low dose Bayluscide on snail hosts of schistosome and selected non-target organisms in sahelian Cameroon
Fonte: Mem. Inst. Oswaldo Cruz;101(4):355-358, June 2006. tab.
Idioma: en.
Resumo: More than 85 percent of all cases of schistosomiasis in Cameroon occur in the northern sahelian half of the country representing 20 percent of the population. Several workers have advocated the integrated approach to schistosomiasis control, including snail control, but the death and decay of aquatic organisms, and fish kill that often follows Bayluscide application at the dose of 1g/m³ decrease its acceptability. The present study was designed to assess the effect of lower Bayluscide doses on snail host and non-target fish, frog, the tadpole kill. Bayluscide was applied to study ponds at concentrations of 0, 0.25, 0.5, and 1 g/m³ (ppm). Pre and post application assessment of snails hosts of schistosomes, fish, frog, and tadpole kill were carried out. All 0.25, 0.5, and 1 g/m³ Bayluscide concentrations reduced snail population significantly. Bayluscide concentration of 0.50 g/m³ applied in two rounds of 0.25 g/m³ resulted in high snail mortality and low lethality to fish, frogs, and tadpoles. Further studies are needed to assess the cost-effectiveness of Bayluscide in the control of schistosomiasis following the simplified approach.

Título: Early sporogonic development in local vectors of Plasmodium falciparum in rural Cameroon
Fonte: Mem. Inst. Oswaldo Cruz;89(Suppl.2):23-26, 1994.
Idioma: en.
Resumo: In ongoing studies on experimental transmission of Plasmodium falciparum in the city of Yaounde gametocyte carriers are daily being identified among dispensary patients with malaria-like complaints. This species comprises 93 of all parasitemias and because of the selection criteria most patients have it as a recent infection. 17 of all P. falciparum-positives carry detectable gametocytes with little difference between youngsters and adults. Blood of adult carriers is taken and infection of Anopheles gambiae mosquitoes is attempted by membrane feeding; the establishment of infection is judged by the presence of oocysts.

Título: Effect of Chloroquine Prophylaxis on Birthweight and Malaria Parasite Load among pregnant women delivering in a regional hospital in Cameroon
Fonte: West Indian med. j;49(2):143-7, Jun. 2000. tab.
Idioma: en.
Resumo: This survey was conducted between December, 1997 and August, 1998 at the Chantal Biya Maternity Section of the Ebolowa Provincial Hospital, Cameroon. A total of 231 parturient mothers who gave birth to 232 neonates were included in the study. Ninety-five of them (41.1 percent) took anti-malaria prophylaxis (chroloquine) in the index pregnancy, and 136 (58.9 percent) did not. Both groups were similar with respect to socio-demographic characteristics except for educational level of the mother, which was significantly higher in the group on prophylaxis (x2 = 8.05; df = 2, p = 0.02). The overall prevalence of maternal parasitaemia was 37.2 percent. The group on chloroquine (TG) experienced a lesser parasitaemia (26.3 percent) than the non-prophylactic group (CG) (44.9 percent odds ratio (OR) = 2.28, CI = 1.24 - 4.19). The proportion of women with severe parasitaemia (>4000 parasites/ul) was also lower in the TG than CG (17.6 percent vs. 7.3 percent; OR = 2.69, CI = 1.04 - 7.23). A modest reduction in low birthweight was found in the TG which was not significant (23.4 percent vs 16.0 percent; p = 0.16). In conclusion, chloroquine given to prevent malaria in pregnancy was found to be effective in reducing peripheral malaria parasitaemia, but improvement in birthweight could not be demonstrated. Among other factors, impaired biological activity of the drug at the level of the placenta where parasite sequestration frequently occurs might be the explanation. We recommend that further investigation be carried out in the study area to evaluate this finding, and if confirmed, institute appropriate changes in the present policy of chloroquine prophylaxis in pregnancy.
