Evaluation of blood cell count parameters as predictors of treatment failure of malaria in Angola: An observational study.

BACKGROUND: Despite the guidelines provided by the World Health Organization for the treatment of malaria, treatment failure occurs in many hospitalized patients. OBJECTIVE: Evaluate whether blood cell count parameters may serve as predictors for malaria treatment. METHODOLOGY: A cross-sectional study with a quantitative approach. RESULTS: Of the 219 patients, 21.5% showed failure to antimalarial treatment, Patient with 21 and 40 years (72.6%), male (53.4%), from peri-urban area (47.5%), with high parasitemia (59.8%), treated with Arthemeter (90.9%) and the mortality were 5.9%. Significant associations were observed between occupation, level of parasitemia and outcome with resistance to antimalarial treatment (p<0.05). Patients with normal Hb [OR: 0.75 (95% CI: 0.39-1.44), p = 0.393], RBC [OR: 0.83 (95% CI: 0.40-1.72), p = 0.632], RDW [OR: 0.54 (95% CI: 0.27-1.09), p = 0.088], MCV [OR: 0.61 (95% CI: 0.28-1.31), p = 0.204] were less likely to have malaria treatment failures after artemisinin-based therapy failure. In contrast, those with normal values of segmented neutrophils [OR: 0.32 (95% CI: 0.11-0.96), p = 0.042] and lymphocyte counts [OR: 0.24 (95% CI: 0.05-1.04), p = 0.055]. We also found that patients with significant low levels of Hct [OR: 0.31 (95% CI: 0.15-0.64) p = 0.002], and high leukocytes [OR: 8.88 (95% CI: 2.02-37.2), p = 0.004] and normal platelet values [OR: 1.42 (95% CI: 0.73-2.95), p = 0.280] demonstrated high probability of treatment failure. CONCLUSION: The importance of blood cell count parameters in monitoring malaria therapy necessitates the urgent need to re-evaluate Artemether-based therapy. Future studies involving more participants in different settings are needed to provide further evidence.

Community Pharmacy Services in Malanje City, Angola: A Survey of Practices, Facilities, Equipment, and Staff.

A community pharmacy, also known as a retail pharmacy, is the most common type of pharmacy that allows the public access to their medications and advice about their health. The conditions existing in the community pharmacy, as well as the qualification of the staff who work there, are fundamental for the compliance of good pharmacy practices. OBJECTIVE: To assess the practices, facilities, equipment, and personnel of community pharmacies in the Municipality of Malanje. METHODS: A cross-sectional observational study with a quantitative and qualitative approach. Through a simple random sampling technique, 20 pharmacies were selected from a universe of 73 reported by official authorities. RESULTS: no pharmacist was acting in the local pharmacies, and their activity was supported by other professionals, particularly intermediate nursing technicians (57%). Most pharmacies were in the peri-urban area, and their functional areas, equipment, and utilities were not in accordance with Angolan law. In addition, the distribution of some drugs that are not over-the-counter was observed. CONCLUSION: community pharmacies in Malanje develop their activity in disregard of the law, constituting a considerable weakness that affects the observance of pharmacy service standards.

Factors Associated With Resistance to In-Hospital Treatment of Malaria in Angolan Patients.

Background: Malaria is a public health problem, particularly in low- and middle-income countries. In Angola, it is the leading cause of death, morbidity, and absenteeism from work and school. Objective: To evaluate the social and clinical factors associated with resistance to in-hospital treatment. Methodology: A prospective analytical cross-sectional study with a quantitative approach was conducted including 220 patients with malaria. Results: Of the 220 patients enrolled, the majority were between 21 and 40 years old (72.7%), male (53.6%), of peri-urban areas (47.7%), employees (46.4%), and with high parasitemia levels (57.7%). Of the remaining hospitalized patients (61.4%), 20.9% were resistant to treatment. The resistance risk was higher in patients over 40 years [OR: 5.91 (95% CI: 0.76-45.7), P = .088], from rural regions [OR: 2.48 (95% CI: 0.95-6.48), P = .064], that were unemployed [OR: 1.06 (95% CI: 0.52-2.15), P = .859], presenting high parasitemia [OR: 1.95 (95% CI: 1.02-3.75), P = .043] and who remained hospitalized [OR: 5.28 (95% CI: 0.63-43.1), P = .121]. The risk to develop resistance was lower in patients that were students [OR: 0.04 (95% CI: 0.01-0.37), P = .004], patients who were treated with dipyrone [OR: 0.06 (95% CI: 0.01-0.24), P < .001], metoclopramide [OR: 0.25 (95% CI: 0.09-0.67), P = .006] and ciprofloxacin [OR: 0.22 (95% CI: 0.11-0.44), P < .001]. Conclusion: Treatment with antimalarial drugs as well as the use of adjuvants such as dipyrone, metoclopramide, ciprofloxacin, and diazepam can reduce the chances of developing resistance to malaria treatment, however, it is necessary to carry out further in-depth studies.

The transcriptional regulator NtrC controls glucose-6-phosphate dehydrogenase expression and polyhydroxybutyrate synthesis through NADPH availability in Herbaspirillum seropedicae.

The NTR system is the major regulator of nitrogen metabolism in Bacteria. Despite its broad and well-known role in the assimilation, biosynthesis and recycling of nitrogenous molecules, little is known about its role in carbon metabolism. In this work, we present a new facet of the NTR system in the control of NADPH concentration and the biosynthesis of molecules dependent on reduced coenzyme in Herbaspirillum seropedicae SmR1. We demonstrated that a ntrC mutant strain accumulated high levels of polyhydroxybutyrate (PHB), reaching levels up to 2-fold higher than the parental strain. In the absence of NtrC, the activity of glucose-6-phosphate dehydrogenase (encoded by zwf) increased by 2.8-fold, consequently leading to a 2.1-fold increase in the NADPH/NADP+ ratio. A GFP fusion showed that expression of zwf is likewise controlled by NtrC. The increase in NADPH availability stimulated the production of polyhydroxybutyrate regardless the C/N ratio in the medium. The mutant ntrC was more resistant to H2O2 exposure and controlled the propagation of ROS when facing the oxidative condition, a phenotype associated with the increase in PHB content.
