Evidence quality will be evaluated using the GRADE system. ETHICS AND DISSEMINATION This network meta-analysis will not involve private information from personal or imperil their rights, so, ethical approval is not required. The results of this network meta-analysis may be published in a journal or publicized in concerned conferences.The value of dual imaging mode for the severity assessment of Parkinson disease (PD) is explored by conducting positron emission tomography computed tomography (PET/CT) double imaging using combined 18-fluorine flurodeoxyglucose (F-FDG) brain metabolism and 11C-2β-carbomethoxy-3β-(4-fluorophenyl) tropane (C-CFT) brain dopamine transporter (DAT).A total of 102 patients with PD and 50 healthy people in the control group are enrolled for the PET/CT dual imaging of F-FDG brain metabolism and C-CFT brain DAT. The characteristics of F-FDG PET/CT and C-CFT PET/CT imaging are analyzed by delineating the region of interest. Differences in the glucose metabolism and DAT distribution in the basal ganglia of patients with PD and healthy control group in the PET/CT imaging and the radioactive distribution characteristics of cerebral cortex in glucose metabolism imaging are compared. The characteristics of PET/CT imaging of C-CFT brain DAT in the ganglion region in absorbing C-CFT in different PD groups are analyzed.Compars high application value for the severity assessment of PD.BACKGROUND Through this analysis, we aimed to systematically compare the cardiovascular outcomes observed in patients with co-existing coronary artery disease (CAD) and rheumatoid arthritis (RA). METHODS Mendeley, Web of Science (WOS), MEDLINE, Cochrane central, EMBASE, Google scholar, and http//www.ClinicalTrials.gov were searched for English-based publications on CAD and RA. Selective cardiovascular outcomes were the endpoints in this analysis. The statistical software RevMan 5.3 was used for data assessment. Risk ratios (RR) with 95% confidence intervals (CI) were used to represent each subgroup analysis. RESULTS One thousand four hundred forty six (1446) participants had co-existing CAD and RA whereas 205,575 participants were in the control group (only CAD without RA). This current analysis showed that the risk of asymptomatic or stable angina was similar in CAD patients with versus without RA (RR 0.98, 95% CI 0.84 - 1.14; P = .78). However, all-cause mortality (RR 1.47, 95% CI 1.34 - 1.61; P = 0.00001),manifested more in CAD patients with co-existing RA. However, the risks all the other cardiovascular outcomes were similar in both groups. Nevertheless, due to the several limitations of this analysis, this hypothesis should be confirmed in forthcoming trials based on larger numbers of CAD patients with co-existing RA.Although serum thyroglobulin (Tg) is a reliable differentiated thyroid carcinoma (DTC) prognostic marker, its cutoff values can be affected by TSH stimulation status. Serum Tg prognostic values measured at different time points before and after radioactive iodine (RAI) therapy prepared with recombinant human TSH (rhTSH) in DTC patients, were investigated.This study included 160 DTC patients who underwent surgery followed by rhTSH-aided RAI therapy. Their serum Tg levels were measured 7 days before (D-7Tg), on the day of (D0Tg), and 2 days after (D2Tg) the RAI therapy. For response evaluation, the patients were classified into 2 groups acceptable response and non-acceptable response (non-AR). Optimal Tg level cutoff values measured at different time points were evaluated for persistent or recurrent disease (PRD) prediction, as well as therapeutic response.Multivariate analysis showed that D-7Tg, D0Tg, and D2Tg significantly predicted non-AR (P  less then  .05, for all). Lys05 Optimal Tg level cutoff values for non-AR prediction were 0.6, 2.6, and 3.7 ng/mL for D-7Tg, D0Tg, and D2Tg, respectively. Cox regression analysis showed that Tg levels were significantly associated with PRD free survival with D-7Tg, D0Tg, and D2Tg cutoff values of 0.8, 4.0, and 6.0 ng/mL, respectively (D-7Tg, P = .010; D0Tg, P = .005; D2Tg, P = .011).Serum Tg levels measured at the different time points could predict PRD free survival as well as therapeutic response with different cutoff values in DTC patients who underwent rhTSH-aided RAI therapy.Currently, the association of the initiation time of hepatitis B virus (HBV) screening and antiviral prophylaxis with adverse liver outcomes in cancer patients undergoing chemotherapy remains conflicting.This retrospective study was designed to determine the association of HBV screening and antiviral prophylaxis with adverse liver outcomes, and then proposed optimal management strategies on HBV screening and antiviral prophylaxis.We analyzed the medical data of Chinese cancer patients undergoing chemotherapy between 2000 and 2015. Descriptive statistics and Chi square tests were performed to analyze the basic characteristics of patients. Time-to-event analysis was used to determine incidence, and competing risk analysis was used to determine the hazard ratios (HRs) for outcomes.A total of 12,158 patients (81.1% with solid tumors) were analyzed. Among solid tumors patients, late screening and late antiviral therapy of chronic HBV were associated with higher incidence of hepatitis flare (HR 3.29, 95% confidence interval [CI] 2.26-4.79; HR 6.79, 95% CI 4.42-10.41), hepatic impairment (HR 2.96, 95% CI 2.03-4.32; HR 8.03, 95% CI 4.78-13.48), liver failure (HR 2.19, 95% CI 1.41-3.40; HR 14.81, 95% CI 6.57-33.42), and HBV-related death (HR 3.29, 95% CI 2.26-4.79; HR 8.30, 95% CI 4.95-13.91) in comparison with early screening and early therapy.Early HBV screening and antiviral therapy could reduce the risk of adverse liver outcomes among chronic HBV patients receiving chemotherapy. Hepatitis B surface antibody-positivity was associated with a decreased risk of liver failure and chronic HBV, late screening or late antiviral therapy were predictors of liver failure for patients with anti-tumor therapy. However, it should be applied cautiously into each types of solid tumors and hematologic malignancies because subgroup analysis according to type of cancer was not designed.
