In many industrial sectors, workers are exposed to manufactured or unintentionally emitted airborne nanoparticles (NPs). To develop prevention and enhance knowledge surrounding exposure, it has become crucial to achieve a consensus on how to assess exposure to airborne NPs by inhalation in the workplace. Here, we review the literature presenting recommendations on assessing occupational exposure to NPs. The 23 distinct strategies retained were analyzed in terms of the following points: target NPs, objectives, steps, "measurement strategy" (instruments, physicochemical analysis, and data processing), "contextual information" presented, and "work activity" analysis. The robustness (consistency of information) and practical aspects (detailed methodology) of each strategy were estimated. The objectives and methodological steps varied, as did the measurement techniques. Strategies were essentially based on NPs measurement, but improvements could be made to better account for "contextual information" and "work activity". Based on this review, recommendations for an operational strategy were formulated, integrating the work activity with the measurement to provide a more complete assessment of situations leading to airborne NP exposure. These recommendations can be used with the objective of producing homogeneous exposure data for epidemiological purposes and to help improve prevention strategies.

Objectives To evaluate the evidence supporting the efficacy and safety of electroacupuncture for lumbar spinal stenosis. Methods We searched eight electronic databases (PubMed, EMBASE, Cochrane Library, Chinese Academic Journals, Research Information Sharing Service, ScienceOn, KMBASE, DBpia) and related two journals up to March 2023. We included randomized controlled trials of testing electroacupuncture for lumbar spinal stenosis patients. The methodological quality of relevant randomized controlled trials assessed by the Cochrane risk of bias tool. Results Among 90 articles that were searched, seven randomized controlled trials involving 474 participants were finally selected in this systematic review. Electroacupuncture was more effective on lumbar spinal stenosis compared with other treatments including analgesics, acupuncture, bed rest and exercise therapy, but showed ambiguous effect compared with physical therapy. Most of the side effects and adverse reactions were reported as minor and temporary. Conclusions Electroacupuncture for lumbar spinal stenosis was more effective than analgesics, acupuncture, bed rest and exercise therapy. In terms of safety, it was limited because there are many papers that do not mention side effects and adverse reactions related to electroacupuncture. Additional studies are needed to determine the effect of electroacupuncture on lumbar spinal stenosis.

Objectives: Epilepsy is a chronic disease that requires long-term treatment and intervention from health workers. Medication adherence is a factor that influences the success of therapy for patients with epilepsy. Therefore, this study aimed to analyze the role of pharmacists in improving the clinical outcomes of epilepsy patients, focusing on medication adherence. Methods: A scoping literature search was conducted through the ScienceDirect, PubMed, and Google Scholar databases. The literature search included all original articles published in English until August 2023 for which the full text was available. This scoping review was carried out by a team consisting of pharmacists and neurologists following the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) Extension for Scoping Reviews and the Joanna Briggs Institute guidelines, including 5 steps: identifying research questions, finding relevant articles, selecting articles, presenting data, and compiling the results. Results: The literature search yielded 10 studies that discussed pharmacist interventions for patients with epilepsy. Five articles described educational interventions involving drug-related counseling with pharmacists. Two articles focused on similar pharmacist interventions through patient education, both verbal and written. Three articles discussed an epilepsy review service, a multidisciplinary intervention program involving pharmacists and other health workers, and a mixed intervention combining education and training with therapy-based behavioral interventions. Conclusions: Pharmacist interventions have been shown to be effective in improving medication adherence in patients with epilepsy. Furthermore, these interventions play a crucial role in improving other therapeutic outcomes, including patients' knowledge of self-management, perceptions of illness, the efficacy of antiepileptic drugs in controlling seizures, and overall quality of life.

Objectives: This study was aimed at evaluating the effectiveness and safety of Danggui buxue decoction (DBD) for iron deficiency anemia (IDA) by systematic review and meta-analysis of the randomized controlled trials (RCTs). Methods: Randomized controlled trials on the treatment of DBD for IDA patients were selected from among the literature published from the beginning of each database to May 30, 2023 in nine domestic and foreign databases (PubMed, EMBASE, Cochrane, Chinese Academic Journals (CAJ), CiNii Research, J-STAGE, Oriental Medicine Advanced Searching Integrated System (OASIS), Research Information Sharing Service (RISS), and ScienceON). The quality of the literature was evaluated using the Cochrane ROB tool 2.0 (ROB2) and GRADE method. The meta-analysis was conducted using RevMan5.4. Results: A total of 636 patients with IDA were finally selected from the 7 RCTs. The meta-analysis showed that the treatment groups that underwent both DBD and conventional treatment were statistically higher than the control groups that performed only conventional treatment in all indicators that showed effectiveness of DBD such as red blood cell (mean difference (MD) 0.38×10¹²/L, 95% CI: 0.16-0.60), hemoglobin (MD 12.45 g/L, 95% CI: 10.27-14.63), serum ferritin (MD 3.50 ㎍/L, 95% CI: 1.71-5.29), and total effective rate (relative risk (RR) 1.13, 95% CI: 1.05-1.21). The incidence of adverse events was 0.39 times lower in the DBD group than in the conventional group (RR 0.39, 95% CI: 0.22-0.70). Conclusion: This study demonstrated the effectiveness and safety of DBD with conventional treatment and further provided a basis for administering DBD to patients with IDA in clinical treatment.
