Female genital mutilation/cutting: Knowledge, practice and experiences of secondary schoolteachers in North Central Nigeria

Background. Despite global efforts at eradicating female genital mutilation/cutting (FGM/C), the act continues to be performed globally. Objective. To determine the experience of schoolteachers about FGM/C and their possible role in contributing to its eradication. Methods. A prospective cross-sectional survey involving secondary schoolteachers from 18 secondary schools in Ilorin, North Central Nigeria, was undertaken during October and November 2014. All consenting participants completed a self-administered questionnaire on FGM/C. Statistical analysis was with SPSS version 20.0 with χ2 and logistic regression; a p-value of <0.05 was considered significant. Results. There were 371 participants (113 males (30.5%) and 258 females (69.5%)). More females than males were aware of FGM/C (205 v. 94; χ2 41.2; p=0.001); 180 women (69.8%) and 81 men (71.7%) wanted awareness and the implications of FGM/C to be taught in schools, while 46 women (17.8%) and 23 men (20.4%) had previously educated students about FGM/C. Also, 109 (42.3%) of the female teachers had been mutilated (mean (standard deviation) age 4.76 (4.86) years), and 49 mutilations (45.0%) had been performed by traditional circumcisers. Of the teachers, 44.0% of men and 24.5% of women had subjected their daughters to FGM/C (p=0.029), mostly for religious reasons. The men initiated the majority of their daughters' mutilations, while the mothers-in-law were the main initiators among the women; 44 (17.0%) women and 23 (20.4%) men held the opinion that females should be circumcised, while the majority considered education and legislation to be the most important interventions to encourage its eradication. Predictors of the likelihood to support discontinuation of FGM/C include awareness of government policy about FGM/C and having a mutilated daughter. Conclusion. Education, reorientation and motivation of teachers will position them as agents for eradicating FGM/C

Comparative effects of the short QT N588K mutation at 37 degrees C on hERG K+ channel current during ventricular, Purkinje fibre and atrial action potentials: an action potential clamp study.

The short QT syndrome (SQTS) is a cardiac repolarisation disorder characterised by abbreviated QT intervals on the electrocardiogram and by an increased risk of atrial and ventricular arrhythmias and sudden death. The SQT1 variant involves a gain-of-function mutation (N588K) that impairs inactivation of the hERG (human ether-a-go-go-related gene) potassium channel and, thereby, increases current mediated by the rapid delayed rectifier potassium current (I(Kr)) in the heart. Here, the action potential voltage clamp (AP clamp) technique was applied to Chinese Hamster Ovary cells expressing wild-type or N588K-hERG at 37 degrees C, to compare effects of the N588K mutation on hERG current (I(hERG)) during ventricular, atrial and Purkinje fibre APs. The N588K mutation altered the I(hERG) profile during each AP type; increased maximal repolarising current occurred earlier during AP repolarisation (with shifts of +60 mV, +30 mV and +15 mV respectively for ventricular, Purkinje fibre and atrial APs). Thus SQT1 may influence repolarising I(hERG) for each cell type, with AP clamp experiments and simulation data indicating the greatest effect during ventricular APs. Changes in the timing of outward I(hERG) transients elicited by premature stimuli following AP commands indicate that SQT1 may alter the protection that hERG provides cardiac tissue against premature arrhythmogenic stimuli.
