Past research has focused on typhoid fever surveillance with little attention to implementation methods or effectiveness of control interventions. This study purposefully sampled key informants working in public health in Chile, India, Pakistan, Bangladesh, Thailand, Vietnam, South Africa, and Nigeria to 1) scope typhoid-relevant interventions implemented between 1990 and 2015 and 2) explore contextual factors perceived to be associated with their implementation, based on the Consolidated Framework for Implementation Research (CFIR). We used a mixed methods design and collected quantitative data (CFIR questionnaire) and qualitative data (interviews with 34 public health experts). Interview data were analyzed using a deductive qualitative content analysis and summary descriptive statistics are provided for the CFIR data. Despite relatively few typhoid-specific interventions reportedly implemented in these countries, interventions for diarrheal disease control and regulations for food safety and food handlers were common. Most countries implemented agricultural and sewage treatment practices, yet few addressed the control of antibiotic medication. Several contextual factors were perceived to have influenced the implementation of typhoid interventions, either as enablers (e.g., economic development) or barriers (e.g., limited resources and habitual behaviors). Consolidated Framework for Implementation Research factors rated as important in the implementation of typhoid interventions were remarkably consistent across countries. The findings provide a snapshot of typhoid-relevant interventions implemented over 25 years and highlight factors associated with implementation success from the perspective of a sample of key informants. These findings can inform systematic investigations of the implementation of typhoid control interventions and contribute to a better understanding of the direct effects of implementation efforts.

Studies of human genetics have implicated the role of SIRT1 in regulating obesity, insulin resistance, and longevity. These researches motivated the identification of novel SIRT1 activators. The current study aimed to investigate the potential efficacy of agrimol B, a polyphenol derived from Agrimonia pilosa Ledeb., on mediating SIRT1 activity and fat metabolism. Results showed that agrimol B significantly induced cytoplasm-to-nucleus shuttle of SIRT1. Furthermore, we confirmed that agrimol B dramatically inhibited 3T3-L1 adipocyte differentiation by reducing PPARγ, C/EBPα, FAS, UCP-1, and apoE expression. Consequently, adipogenesis was blocked by treatment of agrimol B at the early stage of differentiation in a dose-dependent manner, the IC50 value was determined as 3.35 ± 0.32 μM. Taken together, our data suggest a therapeutic potential of agrimol B on alleviating obesity, through modulation of SIRT1-PPARγ signal pathway.

A sensitive and accurate liquid chromatography coupled with mass spectrometry (LC-MS) method was developed for the determination of agrimol B, a main active ingredient isolated from Agrimonia pilosa Ledeb., in rat plasma. Chromatographic separation was achieved on a Zorbax CN column (150 × 4.6 mm, 5 µm), with isocratic elution consisting of acetonitrile and water (15:85, v/v) at a flow rate of 0.6 mL/min. Agrimol B and dryocrassin ABBA, an internal standard (IS), were analyzed by selected ion monitoring at m/z transitions of 681.3 and 819.4, respectively. This assay exhibited a good linearity with a correlation coefficient >0.99 and showed no endogenous interference with the analyte and IS. The limit of quantification of agrimol B was 8.025 ng/mL with acceptable precision and accuracy. The method was successfully applied in the pharmacokinetic study of agrimol B in rats after intravenous (1 mg/kg) and oral (2, 5 and 10 mg/kg) doses of agrimol B. The absolute bioavailability of agrimol B was 16.4-18.0% in rat. Our study clarifies the pharmacokinetic behavior of agrimol B in animals.
