Loss to follow-up before and after initiation of antiretroviral therapy in HIV facilities in Lilongwe, Malawi

Although several studies have explored factors associated with loss to follow-up (LTFU) from HIV care, there remains a gap in understanding how these factors vary by setting, volume of patient and patients’ demographic and clinical characteristics. We determined rates and factors associated with LTFU in HIV care Lilongwe, Malawi

Geospatial transmission hotspots of recent HIV infection — Malawi, October 2019–March 2020

What is already known about this topic? A novel HIV infection surveillance initiative was implemented in Malawi to collect data on recent HIV infections among new diagnoses to characterize the epidemic and guide the public health response. What is added by this report? Higher proportions of recent infections were identified among females, persons aged <30 years, and clients at maternal and child health and youth clinics. Spatial analysis identified three hotspots of health facilities with significantly higher rates of recent infection than expected across five districts. What are the implications for public health practice? Geospatial analysis of recent HIV infection surveillance data can identify potential transmission hotspots. This information could be used to tailor program activities to strengthen HIV testing, prevention, and treatment services and ultimately interrupt transmission

Asymmetric Responses of the Underground Economy to Tax Changes: Evidence From New Zealand Data

We consider the relationship between taxes and the size of the underground economy in New Zealand. Previous studies indicate that a positive relationship exists in this and certain other countries. We address the following question: "Is the response of the underground economy to an increase in taxes the same as its response to a decrease in taxes?" To answer this question we modify an existing methodology for testing for both "timing symmetry" and "pattern symmetry". Paying careful attention to the non-stationarity and cointegration of our annual data, we test for the presence of such symmetry in the tax-evasion relationship for New Zealand. We find that although the effect on the underground economy of an upward movement in the effective tax rate is numerically greater than that of a downward tax movement, this difference is not statistically significant in either the short-run or the long-run. Elasticity and multiplier calculations allow us to quantify some of the effects of changes in taxation policy on hidden output.Tax evasion, underground economy, tax rates, asymmetry

Tef [Eragrostis tef (Zucc.) Trotter] Breeding

Tef or teff Eragrostis tef (Zucc.) Trotter, a cereal crop which adapts to extreme climatic and soil conditions, is extensively cultivated in the Horn of Africa. It is also considered as nutritious and a life-style crop due to its richness in essential nutrients and health-related benefits. However, the productivity of the crop is extremely low due to little scientific improvement made globally. It is, therefore, in the category of orphan crops. Together with all cereal crops, tef belongs to the Grass or Poaceae family. The improvement of tef focuses on selection and hybridization techniques. However, recently, molecular and high-throughput techniques have also been implemented to a limited scale. Forty-two tef varieties were approved for release by the Ethiopian National Variety Release Committee in the past four decades. Due to the adoption of improved varieties and technologies, the national average yield of tef has more than doubled over the last 20Â years. This review describes the progress in tef breeding and variety development as well as dissemination of the improved varieties to the farming community
