Background Malaria is the main cause of morbidity and mortality among children under the age of five years in Malawi. The aim of this study was to compare the prevalence and factors associated with malaria parasitaemia among children under the age of five years in Malawi between the 2014 and 2012 Malaria Indicator Surveys (MISs). Methodology Data on demographic factors, vector control interventions, and blood for malaria test were collected from a representative sample of children under the age of five years in Malawi through multistage cluster sampling method. Data were analysed by chi-square test and logistic regression using complex samples analysis of the Statistical Package for the Social Sciences (SPSS) version 22.Results The prevalence of malaria parasitaemia among children under the age of five years increased from 28% in 2012 to 33% in 2014 (p > 0.05). Likewise, the proportion of children using long-lasting insecticide-treated net (LLIN) increased significantly from 54% in 2012 to 65% in 2014 MIS (p < 0.05). The proportion of households that had used indoor residual spraying (IRS) was 9% for both surveys. In multivariate analysis, use of LLIN significantly predicted for malaria parasitaemia in the 2012 MIS but not in the 2014 MIS. Older children and those coming from the poorest families were significantly associated with having malaria parasites in both surveys. Conclusion The increase in the use of LLIN among children in 2014, did not result in the reduction of malaria parasitaemia in children. The use of LLIN significantly predicted for malaria parasitaemia among children in the 2012 MIS but not in the 2014 MIS. The results of this study underscore the need to increase the coverage of IRS, mosquito repellents and larvicide alongside LLINs in order to reduce the burden of malaria among children in Malawi

Nursing and midwifery students\u27 experiences and perception of their clinical learning environment in Malawi: A mixed-method study

© 2020 The Author(s). Background: The clinical learning environment is an important part of the nursing and midwifery training as it helps students to integrate theory into clinical practice. However, not all clinical learning environments foster positive learning. This study aimed to assess the student nurses and midwives\u27 experiences and perception of the clinical learning environment in Malawi. Methods: A concurrent triangulation mixed methods research design was used to collect data from nursing and midwifery students. Quantitative data were collected using a Clinical Learning Environment Inventory, while qualitative data were collected using focus group discussions. The Clinical Learning Environment Inventory has six subscales of satisfaction, involvement, individualisation, innovation, task orientation and personalisation. The focus group interview guide had questions about clinical learning, supervision, assessment, communication and resources. Quantitative data were analysed by independent t-test and multivariate linear regression and qualitative data were thematically analysed. Results: A total of 126 participants completed the questionnaire and 30 students participated in three focus group discussions. Satisfaction subscale had the highest mean score (M = 26.93, SD = 4.82) while individualisation had the lowest mean score (M = 18.01, SD =3.50). Multiple linear regression analysis showed a statistically significant association between satisfaction with clinical learning environment and personalization (β = 0.50, p = \u3c 0.001), and task orientation (β =0.16 p = \u3c 0.05). Teaching and learning resources, hostile environment, poor relationship with a qualified staff, absence of clinical supervisors, and lack of resources were some of the challenges faced by students in their clinical learning environment. Conclusion: Although satisfaction with clinical learning environment subscale had the highest mean score, nursing and midwifery students encountered multifaceted challenges such as lack of resources, poor relationship with staff and a lack of support from clinical teachers that negatively impacted on their clinical learning experiences. Training institutions and hospitals need to work together to find means of addressing the challenges by among others providing resources to students during clinical placement

Exchange Rate and Inflation Dynamics in a Resource Rich Setting: The Case of Zambia

This paper investigates the relationship between copper prices, the exchange rate and consumer price inflation in Zambia using a structural vector autoregression with quarterly data for 1995–2014 and a combination of sign and zero restrictions to identify relevant global and domestic shocks. The paper makes two contributions. First, it provides new measures of exchange rate pass through (ERPT), based on less restrictive assumptions than previous estimates, to show how changes in the value of the kwacha are reflected in changes in consumer prices (distinguishing food and non‐food inflation). Second, the ERPT is disaggregated to demonstrate that measured ERPT depends on the nature of the shock, with implications for policy responses. Although the price of copper is the most important driver of the exchange rate, the fluctuations it caused are associated with a low pass‐through of about 7% (consistent with a period of relatively low inflation). Exchange rate fluctuations caused by monetary shocks, in contrast, come with a pass‐through of up to 25% (and even more for food prices). A fast response by monetary authorities can mitigate the adverse effects of exchange rate shocks

Detection of Tuberculosis in HIV-Infected and -Uninfected African Adults Using Whole Blood RNA Expression Signatures: A Case-Control Study

BACKGROUND: A major impediment to tuberculosis control in Africa is the difficulty in diagnosing active tuberculosis (TB), particularly in the context of HIV infection. We hypothesized that a unique host blood RNA transcriptional signature would distinguish TB from other diseases (OD) in HIV-infected and -uninfected patients, and that this could be the basis of a simple diagnostic test. METHODS AND FINDINGS: Adult case-control cohorts were established in South Africa and Malawi of HIV-infected or -uninfected individuals consisting of 584 patients with either TB (confirmed by culture of Mycobacterium tuberculosis [M.TB] from sputum or tissue sample in a patient under investigation for TB), OD (i.e., TB was considered in the differential diagnosis but then excluded), or healthy individuals with latent TB infection (LTBI). Individuals were randomized into training (80%) and test (20%) cohorts. Blood transcriptional profiles were assessed and minimal sets of significantly differentially expressed transcripts distinguishing TB from LTBI and OD were identified in the training cohort. A 27 transcript signature distinguished TB from LTBI and a 44 transcript signature distinguished TB from OD. To evaluate our signatures, we used a novel computational method to calculate a disease risk score (DRS) for each patient. The classification based on this score was first evaluated in the test cohort, and then validated in an independent publically available dataset (GSE19491). In our test cohort, the DRS classified TB from LTBI (sensitivity 95%, 95% CI [87-100]; specificity 90%, 95% CI [80-97]) and TB from OD (sensitivity 93%, 95% CI [83-100]; specificity 88%, 95% CI [74-97]). In the independent validation cohort, TB patients were distinguished both from LTBI individuals (sensitivity 95%, 95% CI [85-100]; specificity 94%, 95% CI [84-100]) and OD patients (sensitivity 100%, 95% CI [100-100]; specificity 96%, 95% CI [93-100]). Limitations of our study include the use of only culture confirmed TB patients, and the potential that TB may have been misdiagnosed in a small proportion of OD patients despite the extensive clinical investigation used to assign each patient to their diagnostic group. CONCLUSIONS: In our study, blood transcriptional signatures distinguished TB from other conditions prevalent in HIV-infected and -uninfected African adults. Our DRS, based on these signatures, could be developed as a test for TB suitable for use in HIV endemic countries. Further evaluation of the performance of the signatures and DRS in prospective populations of patients with symptoms consistent with TB will be needed to define their clinical value under operational conditions.

It cannot happen, never: A qualitative study exploring youth views on disclosure of HIV diagnosis to their sexual partners in Southern Malawi

With the availability of antiretroviral therapy, more children living with HIV live longer than before and grow into young adulthood. This study examined the concerns of youth about disclosure of an HIV diagnosis to their sexual partners and attempted to gain an understanding of their HIV status disclosure experiences, views, and plans. A focused ethnography was undertaken. Using semi-structured interviews, data were collected from 20 youth between the ages of 15 and 24 years who were attending an HIV clinic. The findings highlight that youth generally struggled to disclose their HIV status to their sexual partners. The most frequent reasons for concealing their HIV status was fear of relationship termination, being unmarried, and fear that their sexual partners may reveal their HIV diagnosis to the community, thereby predisposing them to stigmatization, discrimination, and prejudice. There is a need to develop and strengthen HIV disclosure support groups for youth to help them develop life skills for overcoming HIV-related stigma

Knowledge and Perception of Sexual Harassment in an Institution of Higher Education in Sub-Saharan Africa

Objective: To find out if Sexual Harassment existed at a higher institute of learning and explore perception of sexual harassment in the university community and to make recommendations based on the findings.Methodology: This was a cross sectional study that collected both primary and secondary data. The participants included 913 students, 90 academic staff and97 non-academic staff who were selected from within the university community. Questionnaires were administered in class for the students and individually with staff members after obtaining informed consent. Secondary data records from 1996 to 2006 on issues to do with sexual harassment from Registrar's department, Deans of students, counselling center, at the university clinic and records from staff and students were collected.Results: The study found that the majority of the participant (54.1%) knew what  sexual harassment was. It was Further found that Fifty seven (57%) of the respondents acknowledged that Sexual Harassment does occur at the university with more females indicating the occurrence of Sexual harassment acts. There washowever a discrepancy in the understanding of what constitutes sexual harassment with the students being the least to identify sexual harassment acts. The study alsorevealed that that more female; students and nonacademic staff identified more  forms of sexual harassment acts and behaviour than the male participants.Conclusion: It could be concluded that Sexual harassment may be a problem at the university. However, despite the varying responses on perceptions of the occurrence of sexual harassment, a university sexual harassment policy should be formulated and implemented at the university in order to deter the would be harassers and protect the potential victi

Criminalising HIV Transmission

Objective: This paper attempts to summarise the global state with regard to the criminalisation of Human Immunodeficiency Virus (HIV) transmission.Method: A comprehensive analysis of both global and Zambian publications, legislation and case laws was conducted.Results: Proponents of criminalisation of HIV transmission argue that criminalization would serve as a deterrent to the culprit and others to engage in prohibited conduct in future while the opponents argue that that there are no well-founded evidences that criminalization of HIV transmission will lead to a reduction in new infections.Conclusion: The onus is on the government and other institutions to critically look at the positive and negative aspects of criminalization of HIV in so far as the legal approach to the fight against the pandemic is concerned. A combination of effective evidence-based approaches should be adopted to expand targeted efforts in preventing new HIV infections in Zambia
