Knowledge, attitudes and practices of cervical cancer screening by health care providers in the Emana health area: Yaounde-Cameroon
Background: Gynaecological cancers and more particularly those of the cervix cause many victims in our country despite the many prevention tools that exist. The objective of this study was to assess the knowledge, attitudes and practices of providers on cervical cancer in the Emana health area.Methods: To achieve this objective, we conducted a cross-sectional study form the period from April 2nd to June 10th, 2019 in the health facilities of the Emana health area.Results: A total of 64 healthcare providers participated in the study, 03 gynecologists and obstetricians, 10 General practitioners, 30 state-certified nurses, 09 midwives, 12 nursing assistants. The majority of these providers had poor knowledge of the causes of the disease (25%), risk factors (34.4%), and means of prevention (39.1%), especially among state nurses (SRN), midwives, nursing assistants. (87.5%) had good knowledge of the clinical signs of the disease and were almost unanimous on the curability of this disease when discovered early (78.1%). The severity of the cancer was perceived by all; however, the practice of screening was low (10.9%). As for their personal screening practices, 73.1% (38/52) of female staff had never been screened.Conclusions: Even though the participants perceive the grave nature of the cervical cancer, the subsequent attitude and screening practices remain poor. The possible barrier to this is the insufficient continuous training and recycling of the health personnel. Emphasis should be laid on the methods of prevention of cervical cancer in the curricula of nurses and midwives in Cameroon
Ăvolution volcanologique du mont Manengouba (Ligne du Cameroun) ; nouvelles donnĂ©es pĂ©trographiques, gĂ©ochimiques et gĂ©ochronologiques<br /> Volcanological evolution of the mount Manengouba (Cameroon line), new petrographical, geochemical, and geochronological data
Le mont Manengouba est un complexe volcanique polygénique de la Ligne du Cameroun édifié au Quaternaire, entre 1,55 et 0 Ma, en trois phases principales. La premiÚre phase, de 1,55 à 0,7 Ma, correspond à la construction du volcan Elengoum. La deuxiÚme, entre 0,7 et 0,56 Ma, est marquée par l'effondrement de la partie sommitale de l'Elengoum. La troisiÚme, de 0,56 à 0 Ma, voit l'édification du volcan Eboga, puis la formation de la caldeira, et comporte une activité fissurale adventive à partir de 0,48 Ma. Les produits émis définissent une série alcaline sodique, allant des basaltes à néphéline à des trachytes. Toutes ces laves ont évolué par cristallisation fractionnée dans une chambre magmatique périodiquement réalimentée. The mount Manengouba is a polygenic volcanic complex of the Cameroon line, which was built in the Quaternary, between 1.55 and 0 Ma, during three stages. The first stage, from 1.55 to 0.7 Ma, corresponds to the building of the Elengoum volcano. The second, between 0.7 and 0.56 Ma, points to the collapse of the Elengoum summit. The third, from 0.56 to 0 Ma, fits with the erection of the Eboga volcano and its caldera sinking, and, from 0.48 Ma, with the adventive fissural activity. The products define an alkaline sodic series, from nepheline-bearing basalts to trachytes. All the lavas evolved by fractional crystallization in a periodically replenished magmatic chamber
Anticancer and antibacterial secondary metabolites from the endophytic fungus Penicillium sp. CAM64 against multi-drug resistant Gram-negative bacteria.
Background: The emergence of multiple-drug resistance bacteria has
become a major threat and thus calls for an urgent need to search for
new effective and safe anti-bacterial agents. Objectives: This study
aims to evaluate the anticancer and antibacterial activities of
secondary metabolites from Penicillium sp. , an endophytic fungus
associated with leaves of Garcinia nobilis . Methods: The culture
filtrate from the fermentation of Penicillium sp. was extracted and
analyzed by liquid chromatography\u2013 mass spectrometry, and the
major metabolites were isolated and identified by spectroscopic
analyses and by comparison with published data. The antibacterial
activity of the compounds was assessed by broth microdilution method
while the anticancer activity was determined by the
3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay.
Results: The fractionation of the crude extract afforded penialidin A-C
(1-3), citromycetin (4), p-hydroxyphenylglyoxalaldoxime (5) and
brefelfin A (6). All of the compounds tested here showed antibacterial
activity (MIC = 0.50 \u2013 128 \u3bcg/mL) against Gramnegative
multi-drug resistance bacteria, Vibrio cholerae (causative agent of
dreadful disease cholera) and Shigella flexneri (causative agent of
shigellosis), as well as the significant anticancer activity (LC50 =
0.88 \u2013 9.21 \u3bcg/mL) against HeLa cells. Conclusion: The
results obtained indicate that compounds 1-6 showed good antibacterial
and anticancer activities with no toxicity to human red blood cells and
normal Vero cells
First delivery of a COVID-19 positive patient in Cameroon
Since its appearance in China in December 2019, COVID-19 which is caused by the SARS-CoV-2 virus has become a real global health problem. Pregnant women are not immune to this novel infection, which makes it difficult for proper management of pregnancy and childbirth. Authors present here the first case of childbirth in Cameroon of a 19-year-old adolescent tested positive for COVID-19
MODES DE FINANCEMENT ET INNOVATION TECHNOLOGIQUE DANS LES ENTREPRISES FAMILIALES AU CAMEROUN
Lâobject de cette Ă©tude est dâanalyser lâeffet des modes de financement sur lâinnovation technologique dans les entreprises familiales au Cameroun. De ce fait, nous avons eu recours Ă une dĂ©marche hypothĂ©tico-dĂ©ductive et une approche quantitative. AprĂšs une justification Ă©clairĂ©e par les principales thĂ©ories, la recherche met en relief une Ă©tude empirique qui permet dâexplorer lâeffet quâa les modes de financement sur les innovations dans les entreprises familiales. Les donnĂ©es sont collectĂ©es auprĂšs de 100 entreprises familiales au Cameroun. Ces donnĂ©es recueillies sont soumis grĂące au logiciel Stata 17 Ă diffĂ©rents tests statistiques.
Par le biais de la rĂ©gression logistique, nos rĂ©sultats indiquent que les facteurs financement par dette, financement par action, financement interne et financement public ont une influence significative sur lâinnovation technologique dans les entreprises familiales au Cameroun.
Nos rĂ©sultats indiquent Ă©galement quâune grande majoritĂ© des entreprises sondĂ©es (60%) ont des projets technologiquement innovants retardĂ©s, abandonnĂ©s ou non dĂ©marrĂ©s du fait de lâabsence ou mauvaise connaissance des circuits de financements de l'innovation, du coĂ»t de l'innovation trop Ă©levĂ©, de la lenteur de la mise en place des financements, de la complexitĂ© de montage des dossiers ou de la politique dĂ©libĂ©rĂ©e de l'entreprise et du manque de personnel qualifiĂ©
