Contribution of inflammation to heart failure development in human immunodeficiency virus-infected patients

Aim. To determine the peculiarities of heart failure (HF) development in human immunodeficiency virus (HIV)-infected patients, depending on the blood concentration of C-reactive protein (CRP).Material and methods. This cross-sectional screening clinical trial included 100 patients hospitalized with HIV infection and a history of HF for 28 months. The patients were divided into 2 groups depending on blood CRP concentration. The cut-off point was CRP of 15 mg/l. The first group included 37 HIV-infected patients with HF and blood CRP <15 mg/l, while the second group — 63 HIV-infected patients with HF and CRP concentration ≥15 mg/l. The inclusion criteria were HIV infection and prior HF, stable medical state, taking into account the underlying disease that required hospitalization. The study did not include patients with acute cardiovascular diseases within prior 3 months, acute decompensated and acute heart failure, cancer, infectious diseases, conditions that required surgical intervention. N-terminal pro-brain natriuretic peptide (NT-proBNP) was determined in all patients.Results. Correlation analysis revealed a strong inverse relationship between the blood concentrations of NT-proBNP and CRP (r=-0,639; p<0,005). A ROC curve revealed the most optimal cut-off threshold of 9,8 mg/l (AUC=0,796, p<0,05), which ensures sensitivity of 92,9% (p<0,05) and specificity of 57,6% (p<0,05). The odds ratio (OR) of an increase in NT-proBNP >450 pg/ml, and hence the risk of acute decompensated HF in the presence of a CRP concentration of 1-9,8 mg/l in HIV-infected patients with HF was 44,73 (95% CI=8,62;311,10), while relative risk (RR) — 18,73 (95% CI=4,94;112,94). In the presence of in hospital inflammatory diseases and CRP ≥15 mg/l in HIV-infected patients and prior HF, the RR of acute decompensated HF is reduced by 88% (RR=0,12, 95% CI=0,03-0,33).Conclusion. CRP values from 1 to 9,8 mg/l in HIV-infected patients with HF are predictors of its severity, characterized by a higher incidence of HF with reduced ejection fraction, diastolic dysfunction and left ventricular hypertrophy without significant differences with patients who have CRP >9,8 mg/l. CRP concentration >9,8 mg/l in HIV-infected patients and prior HF indicates the development of an inflammatory process, and not a worsening of the HF course

Biological control of the millet head miner Heliocheilus albipunctella in the Sahelian region by augmentative releases of the parasitoid wasp Habrobracon hebetor: effectiveness and farmers’ perceptions

On-farm augmentative releases of the parasitoid Habrobracon hebetor (Say) for controlling the millet head miner (MHM) Heliocheilus albipunctella (de Joannis) were tested in Burkina Faso, Mali and Niger from 2007 to 2009. In addition, a survey of farmers’ perceptions of insect pests, with particular focus on MHM, and the biological control program (BCP) was carried out. There was a significant increase of MHM parasitization rate after the releases, with up to 97% mortality. The survey on farmers’ perceptions revealed a fair knowledge of the MHM and the ability of farmers to describe the pest and the damage it caused. Farmers claimed that the biocontrol agent H. hebetor is effective and perceived a significant gain in grain yield due to this control strategy. Implications of these findings for a large extension of the MHM biocontrol program are discussed

In Other Words: Translations as Joy and Struggle

An online magazine of works written and translated by multilingual students, faculty, staff, and alumnae fosters diversity and inclusion by creating space for cross-linguistic exchange. The act of translation enhances critical thinking, continued language development, close reading, and analytic skills. The online format encourages re-thinking and makes post-publication revision possible. Employment of multiple languages connects non-English speaking friends and families with the academic lives of students and recognizes the assets multilingual students bring to the Bryn Mawr College community
