Correlates of Behavior Management Strategies among Learners with Autistic Spectrum Disorders in Primary Schools in Western Kenya

Practitioners handling learners with Autistic Spectrum Disorders (ASDs) often feel ill-prepared to effectively manage this disorder.  Quite often, when faced with cases of challenging behaviour, teachers use coping strategies which may be counter-productive. This paper reports the findings of a study that sought to determine factors that influence practitioners’ choice of behaviour management strategies among learners with ASDs in primary schools in Western Kenya. An exploratory analysis set out to determine the practitioners’ perception of challenging behaviour and its influence on the choice of management strategies. The findings of the study revealed that practitioners training, work experience, collaboration and networking with other professionals, staffing levels, and support received from parents of children with ASDs played a significant role in the choice of strategies in management of behaviour presented by learners with ASDs. Keywords: Challenging behavior, Practitioners, Teachers, Autistic Spectrum Disorde

Characterization of smallholder farmers and agricultural credit institutions in Rwanda

The significance of access to agricultural credit in perpetuating agricultural productivity is unquestionable, because it is a means to achieving optimal productivity. The minimization of any barriers to agricultural credit access should, thus, be a global priority. One of the most significant and current barriers to agricultural credit access is information asymmetry which results into mutual distrust between lending institutions and  borrowers in this case the smallholder farmers. To address information asymmetry, both the lending institutions and borrowers need to have definitive descriptive information about either party. Without the profiling of institutions and potential borrowers, an information gap persists, thereby increasing mutual distrust. This study addresses that gap, in the context of Rwanda by characterizing smallholder farmers and agricultural credit institutions. A cross-sectional survey design was used in this study with smallholder farmers and staff in agricultural credit institutions in the Eastern, Western, and Central provinces of Rwanda as the units of analysis. A multistage sampling procedure was used, with stratified sampling of administrative levels spanning from province (stage 1) to districts (stage 2) and sectors (stage 3), followed by a simple random sampling of cells per sector, and the convenience sample of households. Staff in the financial institutions were purposively sampled. The data collected was analyzed using principal component analysis and cluster analysis with the K-means statistic (SPSS version 25). The largest cluster of smallholder farmers has the following characteristics:  household size of 1 to 5 people, farmers with education, owning arable land not exceeding a hectare, with more than five years of farming experience, earning from other off-farm activities, with no dependents under five years of age, and renting less than an acre of land. As for agricultural credit institutions, the largest cluster has following compositions: have mechanisms or measures established for managing loan defaults with the  majority using refinancing, rescheduling, and collateral release, with variable loan payback options, and provide targeted agricultural credit to farmers such as agricultural input premium. The research findings are particularly pertinent for maize- and rice-growing farmers, and how to reduce the information gap and the implications of broadening access to credit to smallholder farmers were discussed. This study emphasizes the need for characterization for both parties to be better informed about the characteristics and dynamics of each other, all in a bid to lessen asymmetric information and thus improve access to credit

A comparative analysis of conventional Pap smear cytology, liquid based cytology and colposcopy clinical impression with colposcopy biopsy histology as gold standard in women undergoing colposcopy in Kenyatta National Hospital

Background: Cervical cancer is one of the most common female malignancies worldwide. Since the introduction of conventional Papanicolaou smear mortality from cervical cancer has reduced considerably. Despite its success, it has sensitivity of only 51% and false negative rate of 5-10%. Approved liquid based cytology (LBC) products by FDA claim a 65-percent increased detection rate of high grade squamous intraepithelial lesions (HGSIL) compared with conventional smears, as well as decreased unsatisfactory sample rates. Evidence shows that liquid based preparation is more sensitive and accurate for the detection of both squamous and glandular lesions of the cervix. Studies of the accuracy of liquid based preparations reports sensitivity of 61-66% and specificity of 82-91%. Objective of current study is to compare the performance of conventional Pap smear cytology, liquid based cytology and colposcopy clinical impression with colposcopic biopsy as the gold standard among women eligible for colposcopy in Kenyatta National Hospital, Kenya.Methods: This was a hospital-based comparative cross-sectional study. Convenient sampling over a period of 4 months was used to recruit clients referred to colposcopy clinic with abnormal Pap smear results.Results: A total of 73 patients referred with abnormal pap smears were recruited into the study. The mean age of the patients was 38 yrs (SD ±10). About 45% of the patients interviewed did not have knowledge of Pap smear testing. Both the results of referral Pap smear and repeat Pap smear were predominantly low grade squamous intraepithelial lesions (LGSIL) or HGSIL. With biopsy results being the gold standard, Liquid based cytology had a higher specificity of 75% when compared with conventional pap smears’ 11%.Conclusions: Even though colposcopy clinical impression has the highest agreement with colposcopy biopsy it’s a diagnostic and not a screening test, hence Liquid based cytology showed better performance as a screening test compared to conventional Pap smear. In general, there was good agreement for cytological results of repeat CPAP and LBC. We therefore recommend that for patients referred with abnormal pap smears requiring a repeat pap smear, liquid based cytology is used due to its higher specificity compared to conventional Pap smear

Food Prices: Eastern and Southern Africa Defy Global Trends

Global food prices started rising sharply in 2006 and reached record levels in the second quarter of 2008. Although domestic food prices in Eastern and Southern Africa (ESA) are not totally unrelated to world prices, a study by the Association for Strengthening Agricultural Research in East and Central Africa (ASARECA), the Regional Strategic and Knowledge Support System for Eastern and Central Africa (ReSAKSS-ECA), and the Consultative Group on International Agricultural Research (CGIAR) Alliance shows that national and regional factors are very important in driving domestic food prices. While global food prices have exhibited declining trends since June 2008, several ESA countries have experienced increasing prices in 2008 and early 2009. The price surges appear to be further fuelled by some of the policy responses that countries have employed in their attempts to address the food price problem. This brief provides an update on food price trends in ESA. It starts by comparing the Food and Agricultural Organization of the United Nations (FAO) global food price index and food price indexes (FPI) in individual countries followed by an update on price trends for specifi c commodities. This information serves to remind policymakers that the easing global food prices do not present any immediate relief to the food crises facing their individual countries

RANDOMISED DOUBLE BLIND STUDY TO COMPARE EFFECTIVENESS OF HONEY, SALBUTAMOL AND PLACEBO IN TREATMENT OF COUGH IN CHILDREN WITH COMMON COLD

Background: Acute upper respiratory infection is the most common childhood illness and presents with cough, coryza and fever. Available evidence suggests that cough medicines may be no more effective than honey-based cough remedies. Objective: To compare effectiveness of honey, salbutamol and placebo in the treatment of cough in children with acute onset cough. Design: Randomised control trial Setting: Aga Khan University Hospital Paediatric Casualty Subjects: Children between ages one to twelve years presenting with a common cold between December 2010 and February 2012 were enrolled. Outcome measures: Frequency, severity and extent to which cough bothered and disturbed child and parental sleep were assessed at baseline and over the subsequent five days through telephone interview using a validated scoring tool. Results: One hundred and forty five children were enrolled in the study (45- placebo, 57 –honey, 43 –salbutamol). Of the 145 children 51% were male. Honey significantly reduced the total mean symptom score by day three (p\u3c 0.001). Total mean difference in scores between day zero to five demonstrated a significant difference of honey’s efficacy over placebo (p\u3c 0.002) however no difference was noted when compared to salbutamol (p\u3c0.478). Significant differences in both total as well as each individual symptom score was detected with honey consistently scoring the best whilst placebo and salbutamol scored the worst. In paired comparisons honey was superior to placebo but not salbutamol, whilst salbutamol was not superior to placebo. Conclusion: Honey was most effective in symptomatic relief of symptoms associated with the common cold whilst salbutamol or placebo offered no benefit

Attempts to identify Cassava Brown Streak Virus in western Democratic Republic of Congo

Open Access ArticleRoot necrosis similar to those of the cassava brown streak disease (CBSD) were observed on cassava in western provinces of the Democratic Republic of Congo (DR.Congo) in the early 2000’s. However molecular laboratory diagnosis were not able to detect any causative agent responsible for the attacks, hence, the disease related to these symptoms was named CBSD-like disease. In order to assess the distribution and the incidence of the CBSD-like disease, surveys were carried out in four western provinces, comprising, Kwango and Kwilu, Sud Ubangi, Kinshasa and Kongo Central. CBSD-like disease was observed in all surveyed provinces on the basis of root symptoms because foliar symptoms were different to those of the documented cases of CBSD in other parts of east Africa. CBSD-like disease incidence was high in Kongo Central and Sud Ubangi, exceeding an average of 50 %, but low in Kwango and Kwilu (32.8%) and in Kinshasa (19.1%). During the surveys, cassava leaf samples were collected for lab identification of the causal agent. PCR diagnosis was done on these samples using primers specific for the two known CBSVs. All samples tested negative with no amplification of DNA fragments of the correct size. Thus, further analysis on the causative organism is needed using Next Generation Sequencing (NGS) approaches. NGS approaches will help also to identify the causative organism in other Central Africa countries (Angola, Congo-Brazzaville and Gabon) where such cassava root necrosis have been reported or are suspected
