Simultaneous therapeutic drug monitoring (TDM) of combination antiretroviral therapy (cART) is critical during pregnancy in order to improve clinical follow-up, monitor viral load, and patient adherence to treatment. A modified simple and fast ultra-high performance liquid chromatography coupled with tandem mass spectrometry and electrospray ionization (UPLC-ESI-MS/MS) method was developed and validated according to national and international guidelines for the simultaneous determination of lamivudine (LMV), zidovudine (ZDV), lopinavir (LPV), and ritonavir (RTV) concentrations in 100-μL plasma sample of Human Immunodeficiency Virus (HIV)-positive pregnant women. Protein precipitation using 0.1% formic acid in cold acetonitrile was used for sample preparation. ⋯ Drug concentrations in patient samples had high inter-individual variability with %CV of 91.98%, 77.54%, 53.80%, and 92.16% for ZDV, LMV, LPV, and RTV, respectively. Two of the 8 patients showed no adherence due to the absence of Protease Inhibitors (PIs) levels in plasma. This technique demonstrated to be effective in therapeutic drug monitoring and is intended to be used in population pharmacokinetics specifically for HIV-positive pregnant women.

Meta Analysis
Effects of weifuchun tablet for chronic atrophic gastritis: A protocol for systematic review and meta-analysis.
Chronic atrophic gastritis (CAG) is defined as an important precancerous disease in the development of gastric cancer. Early intervention of CAG is of great significance in reducing symptoms and blocking its progression to gastric cancer. Weifuchun (WFC) tablet is a classic Chinese patent medicine used to treat CAG. However, there is no systematic review related to WFC for atrophic gastritis published in English. we will conduct systematic review and meta-analysis to provide more evidence on the effectiveness and safety for clinical use of WFC. ⋯ 10.17605/OSF.IO/2UTMB.

Multicenter Study
Risk factors for obstructive complications after endoscopic correction of vesico-ureteral reflux using polyacrylate polyalcohol copolymer.
Use of polyacrylate-polyalcohol copolymer (PPC) after endoscopic correction (EC) of vesico-ureteral reflux (VUR) is highly effective but is associated with a higher risk of obstructive complications (OC) compared with other implants. We undertook a STROBE compliant retrospective investigation and studied the OC risk factors to increase the practical safety of PPC. Overall, 798 patients (464 [58.1%] girls and 334 [41.9%]) boys) from 5 hospitals in whom PPC was routinely used were evaluated retrospectively. ⋯ At multivariate analysis, only male gender (P = .0078), younger age (P = .0044), HIT technique (P < .0001), and second injection (P = .04) represented significant risk factors for the occurrence of OC. We identified young age, male gender, high reflux grade, HIT technique, and second endoscopic injections as factors associated with the risk of OC after EC of VUR using PPC as a bulking agent. Thus, patients who have undergone EC with PPC must be monitored sonographically for occurrence of OC for at least 60 months after the intervention.

Local infiltration analgesia (LIA) has become popular in postoperative pain relief after total hip arthroplasty (THA) or total knee arthroplasty (TKA). The aim of this meta-analysis was to compare the efficacy and safety of LIA with intrathecal morphine and epidural analgesia after THA and TKA. ⋯ LIA provided better postoperative pain control and less adverse events than intrathecal morphine and epidural analgesia after THA and TKA.

Coronavirus disease 2019 (COVID-19) is a global pandemic caused by the Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2). There is no specific cure for this disease, and the clinical management mainly depends on supportive treatment. Traditional Chinese medicines (CHM) is widely used in treating COVID-19 in China. ⋯ 10.17605/OSF.IO/H7GMU.
