Predictors of Antibiotics Co-prescription with Antimalarials for Patients Presenting with Fever in Rural Tanzania.

Successful implementation of malaria treatment policy depends on the prescription practices for patients with malaria. This paper describes prescription patterns and assesses factors associated with co-prescription of antibiotics and artemether-lumefantrine (AL) for patients presenting with fever in rural Tanzania. From June 2009 to September 2011, a cohort event monitoring program was conducted among all patients treated at 8 selected health facilities in Ifakara and Rufiji Health and Demographic Surveillance System (HDSS).It included all patients presenting with fever and prescribed with AL. Logistic regression was used to model the predictors on the outcome variable which is co-prescription of AL and antibiotics on a single clinical visit. A cohort of 11,648 was recruited and followed up with 92% presenting with fever. Presumptive treatment was used in 56% of patients treated with AL. On average 2.4 (1 -- 7) drugs was prescribed per encounter, indicating co-prescription of AL with other drugs. Children under five had higher odds of AL and antibiotics co-prescription (OR = 0.63, 95% CI: 0.46 -- 0.85) than those aged more than five years. Patients testing negative had higher odds (OR = 2.22, 95%CI: 1.65 -- 2.97) of AL and antibiotics co-prescription. Patients receiving treatment from dispensaries had higher odds (OR = 1.45, 95% CI: 0.84 -- 2.30) of AL and antibiotics co-prescription than those from served in health centres even though the deference was not statistically significant. Regardless the fact that Malaria is declining but due to lack of laboratories and mRDT in most health facilities in the rural areas, clinicians are still treating malaria presumptively. This leads them to prescribe more drugs to treat all possibilities

Thermal modelling of gas generation and retention in the Jurassic organic-rich intervals in the Darquain field, Abadan Plain, SW Iran

The petroleum system with Jurassic source rocks is an important part of the hydrocarbons discovered in the Middle East. Limited studies have been done on the Jurassic intervals in the 26,500 km2 Abadan Plain in south-west Iran, mainly due to the deep burial and a limited number of wells that reach the basal Jurassic successions. The goal of this study was to evaluate the Jurassic organic-rich intervals and shale gas play in the Darquain field using organic geochemistry, organic petrography, biomarker analysis, and basin modelling methods. This study showed that organic-rich zones present in the Jurassic intervals of Darquain field could be sources of conventional and unconventional gas reserves. The organic matter content of samples from the organic-rich zones corresponds to medium-to-high-sulphur kerogen Type II-S marine origin. The biomarker characteristics of organic-rich zones indicate carbonate source rocks that contain marine organic matter. The biomarker results also suggest a marine environment with reducing conditions for the source rocks. The constructed thermal model for four pseudo-wells indicates that, in the kitchen area of the Jurassic gas reserve, methane has been generated in the Sargelu and Neyriz source rocks from Early Cretaceous to recent times and the transformation ratio of organic matter is more than 97%. These organic-rich zones with high initial total organic carbon (TOC) are in the gas maturity stage [1.5–2.2% vitrinite reflectance in oil (Ro)] and could be good unconventional gas reserves and gas source rocks. The model also indicates that there is a huge quantity of retained gas within the Jurassic organic-rich intervals

Synthesis, characterization, and antimicrobial evaluation of new pyrazolines incorporating imine moiety

Abstract A novel series of pyrazoline derivatives (3-9) was synthesized and identified by using several spectral analysis. Chalcone compound (1) was prepared as a starting material from the reaction of 4-aminoacetophenone and furan-2-carboxaldehyde in ethanol, using sodium hydroxide as a catalyst. Cyclization reaction of 1 by the action of hydrazine hydride afforded compound 2: 4-(5-(furan-2-yl)-4,5-dihydro-1H-pyrazol-3-yl) aniline. The target compounds (3-9) were obtained from the reaction of 2 with corresponding aldehydes in ethanol. The synthesized compounds were in vitro screened against several bacterial strains: Staphylococcus aureus, Staphylococcus espidermididis, Escherichia coli, Klebsiella sp, as well as, Candida albicans. These compounds exhibit a moderate to good activity.</jats:p

New Pyrazoline Derivatives Containing Imine Moiety: Synthesis, Characterization and Antimicrobial Study

A new series of pyrazoline derivatives (3-10) have been synthesized and characterized on the basis of FT-IR, 1H-NMR, and Mass techniques. 1-(4-Aminophenyl)-3-(pyridin-4-yl)prop-2-en-1-one (1) as a starting material was prepared by the reaction of 4-aminoacetophenone and 4-pyridinecarboxaldehyde in ethanol, using sodium hydroxide as a catalyst. Pyrazoline derivatives 2 was obtained via the cyclization reaction of compound 1 by the action of hydrazine hydrate 80% in ethanol. The target derivatives (3-8) were obtained by the reaction of pyrazoline derivative (2) with the corresponding aldehyde in ethanol. The novel pyrazoline derivatives 9 and 10 were synthesized by the reaction of pyrazoline derivative 2 with the corresponding anhydride (maleic or phthalic anhydride) in presence of anhydrous sodium acetate in glacial acetic acid. The synthesized derivatives were screened against several bacterial strains: Staphylococcus aureus, Staphylococcus espidermididis, Escherichia coli, Klebsiella and Candida albicans. The synthesized compounds showed promising bio-activity compared with amoxicillin.</jats:p
