Efficacy and safety profiles of dolutegravir plus lamivudine vs . bictegravir/emtricitabine/tenofovir alafenamide in therapy-naïve adults with HIV-1 / 中华医学杂志(英文版)

BACKGROUND@#Dual regimen dolutegravir (DTG) plus lamivudine (3TC) has demonstrated non-inferior efficacy compared to DTG-based three-drug regimens (3DRs), yet directly comparative data regarding the efficacy and safety of DTG + 3TC and bictegravir/emtricitabine/tenofovir alafenamide (B/F/TAF) for therapy-naïve people with human immunodeficiency virus (HIV)-1 (PWH) are still limited. We aimed to assess the antiviral potency and safety profiles of DTG + 3TC vs. B/F/TAF based on antiretroviral therapy (ART)-naïve PWH in China.@*METHODS@#This retrospective multicenter study enrolled PWH initiating ART with DTG + 3TC or B/F/TAF from 2020 to 2022 in Guangdong and Guangxi. We analyzed response rates based on target not detected (TND) status using intention-to-treat (ITT) analysis. Subgroups were formed based on baseline viral load (VL) (<100,000 vs . ≥100,000 copies/mL) and CD4 + cell count (<200 vs . ≥200 cell/µL). Median time to TND VL was assessed by Kaplan-Meier method. We also measured changes from baseline in CD4 + cell counts, CD4/CD8 ratio, lipid parameters, weight, creatinine (Cr), estimated glomerular filtration rate (eGFR), and drug-related adverse effects (DRAEs).@*RESULTS@#We enrolled 280 participants, including 137 (48.9%) on DTG + 3TC and 143 (51.1%) on B/F/TAF. At week 48, 96.4% (132/137) on DTG+3TC and 100% (143/143) on B/F/TAF achieved TND ( P = 0.064). At week 12, TND responses were higher with B/F/TAF (78.3% [112/143]) than DTG+3TC (30.7% [42/137]) ( P <0.001). This trend held across subgroups. B/F/TAF achieved TND faster (12 weeks) than DTG+3TC (24 weeks) ( P <0.001). No differences were seen in CD4 + cell count and CD4/CD8 ratio, except in the high-VL subgroup, where B/F/TAF showed better recovery. DRAEs were significantly lower with B/F/TAF (4.9% [7/143]) than with DTG + 3TC (13.1% [18/137]) ( P = 0.016). Lipid parameters, body weight, and Cr increased in both groups over 48 weeks, with DTG+3TC showing a more favorable effect on triglycerides, high-density lipoprotein (HDL) cholesterol, and weight gain.@*CONCLUSIONS@#In this real-life study, B/F/TAF led to a faster viral decline and fewer DRAEs compared to DTG+3TC. No significant difference was observed in the TND rate at week 48, regardless of baseline VL and CD4 + cell count. CD4 + recovery was superior for B/F/TAF in participants with high VL. The DTG + 3TC regimen had less impact on metabolic changes than B/F/TAF.

Research progress on the role and mechanism of 5-hydroxytryptamine and M2 macrophages in pulmonary interstitial fibrosis / 中华危重病急救医学

Idiopathic pulmonary fibrosis (IPF) is a progressive and fatal interstitial lung disease, the cause is not yet clear. Pathological manifestations are abnormal repair changes resulting from sustained lung injury. Macrophages have been identified as playing a key role in IPF pathogenesis. In different local microenvironments, macrophages can exhibit either classically activated (M1) or alternately activated (M2) phenotypes. M1 plays a key role in promoting inflammatory response and is involved in the process of causing alveolar tissue injury. M2 is involved in wound healing and stopping lung inflammation. Previous studies have shown that activation of 5-hydroxytryptamine (5-HT) signaling is enhanced in pulmonary fibrosis and that 5-HT receptors play an important role in the observed pro-fibrotic effects. As a multifunctional signaling molecule, 5-HT is closely related to lung macrophage polarization, early lung tissue injury, abnormal proliferation and repair, and late extracellular matrix (ECM) deposition. This article reviewed the role of 5-HT and M2 macrophages in the pathogenesis of IPF and the possible regulatory mechanism of 5-HT, in order to provide a reference for further research.

Endovascular recanalization for non-acute internal carotid artery occlusion using a new angiographic classification / 中华放射学杂志

Objective:To evaluate the safety and feasibility of endovascular recanalization for non-acute internal carotid artery occlusion (NA-ICAO), and to propose a new angiographic classification.Methods:From April 2015 to October 2019, 95 consecutive patients with symptomatic NA-ICAO who received endovascular recanalization were retrospectively analyzed in Beijing Tiantan Hospital, Capital Medical University. All the patients were divided into four groups according to DSA: type Ⅰ, petrous segments were distally reconstituted by collateral vessels; type Ⅱ, cavernous segments were distally reconstituted by collateral vessels; type Ⅲ, ophthalmic segments were distally reconstituted by collateral vessels; type Ⅳ, communicating segments were distally reconstituted by collateral vessels. Study data including clinical characteristics, surgical details, lesion classification, recanalization rate and perioperative complications. For the counting data, the χ 2 test was used to compare between groups. For the quantitative data, the ANOVA was used for the normal distribution data, otherwise the Kruskal-Wallis H test was used. The primary safety outcome was any stroke or death within 30 days. Results:Among the 95 patients, 67 (70.53%) had successful recanalization. The recanalization rates of type Ⅰ－Ⅳ were 92.31% (36/39), 81.82% (18/22), 47.83% (11/23) and 18.18% (2/11) respectively (χ2=29.557, P<0.001). And the complication rates of the four types were 5.13% (2/39), 13.64% (3/22), 21.74% (5/23) and 9.10% (1/11) respectively. The incidence of perioperative ischemic stroke was 2.11% (2/95). No other serious stroke and death occurred. Conclusions:Endovascular recanalization may be feasible and safe for carefully selected patients with NA-ICAO and therefore represents an alternative treatment. The patients with type Ⅰ and Ⅱ lesions had higher recanalization rates, while the patients with type Ⅳ lesions had significantly lower recalculation rate. The new angiographic classification is conducive to the selection of suitable patients and difficulty in grading.

A comparative analysis of bridging therapy versus direct endovascular treatment in acute ischemic stroke patients aged 80 years and over / 中华老年医学杂志

Objective:To compare the safety and therapeutic effect of bridging therapy versus direct endovascular treatment in patients with acute ischemic stroke(AIS)aged 80 years and over, who received the therapy within 4.5 h of onset.Methods:A total of 89 AIS patients aged 80 years and over receiving the endovascular therapy at our hospital from January 2016 to June 2019 were studied with versus without intravenous thrombolysis before endovascular therapy(the former as bridging therapy group, n=49; the latter as the direct endovascular treatment group, n=40). Baseline information including gender, the modified Rankin scale(mRS)score, medical history, smoking history, preoperative national institute of health stroke scale(NIHSS)score were collected.Clinical data related to the operation including the times from onset to hospital, door-to-puncture and door-to-recanalization, complications(symptomatic cerebral hemorrhage, mortality)and mRS at 90 d after treatment were compared between the two groups.Multiple logistic regression analysis was used to determine whether or not bridging therapy with intravenous thrombolysis was a prognostic factor.Results:There was no significant difference in baseline information between the two groups( P>0.05). The times from onset to hospital, door-to-puncture, door-to-recanalization had no significant difference between the two groups( P>0.05). There was no significant difference in the incidence of symptomatic cerebral hemorrhage and mortality within 90 d between the two groups(26.5% or 13 cases vs. 17.5% or 7 cases, 14.3% or 7 cases vs.7.5% or 3 cases, χ2=1.031 and 1.017, P=0.310 and 0.313). With different clinical outcomes as dependent variables, after adjusting factors such as gender, admission NIHSS and medical history, Logistic regression analysis showed that the bridging therapy with intravenous thrombolysis was not a prognostic factor( OR=0.795, 95% CI: 0.280~2.258, P=0.666). Conclusions:The bridging therapy is as safe and effective as the direct intravascular therapy for AIS patients aged 80 and over within 4.5 hours of onset.The intravenous thrombolysis should be given as soon as possible within time window.

Assessment of the application of clinical pathways for cerebral infarction in patients aged 75 years and above / 中华老年医学杂志

Objective To evaluate the safety and therapeutic efficacy of clinical pathways(CP) for cerebral infarction in patients aged 75 years and above.Methods A cohort of 363 cerebral infarction patients aged 75 years and above after excluding clinical variants were recruited from January 2016 to June 2018 at the neurology department of Nanyang City Center Hospital.Patients were randomly divided into the CP group(n=184)and the control group(n=179).The day-90 modified Rankin scale score(mRS),mortality,incidences of complications,length of hospital stay,total hospital costs and drug costs were compared between the two groups.Results The proportion of patients with mRS 0-1 was higher in the CP group than in the control group(77.2％ or 142/184 vs.55.3％ or 99/179,x2=19.443,P =0.000).The incidences of pulmonary infection(23.9％,44/184)and deep venous thrombosis(14.7 ％,27/184)were lower in the CP group than in the control group(42.5 ％,76/179 & 29.1％,52/179;x2 =14.101,11.014,P=0.000,0.001).There was a significant difference in mortality between the two groups[4.9％ (9/184)vs.11.2％ (20/179),x2 =4.871,P =0.027].There was no significant difference in the other incidences of complications between the groups(P ＞ 0.05).Hospital stay length (18.3 ± 2.9) d,total cost (2.72 ± 0.42) × 104 yuan,and drug cost (0.87±0.29)× 104yuan in the clinical pathway group were lower than those in the control group [(22.8±4.4)d,(3.55±0.81) × 104 yuan,(1.42±0.29) × 104 yuan](t =11.546,12.168 and 18.335,all P =0.000).Conclusions The adoption of clinical pathways can improve medical quality,shorten hospitalization days and reduce hospitalization costs and medical costs in elderly patients with cerebral infarction.

Correlation of memory impairment and cerebral perfusion in patients with vertebral-basilar artery stenosis / 中华行为医学与脑科学杂志

Objective To evaluate the correlation between cerebral blood flow perfusion and memory impairment in patients with severe stenosis of vertebral basilar artery (VBA).Methods 62 cases of patients with VBA stenosis diagnosed by digital subtraction angiography(DSA) in Beijing Tiantan Hospital from September 2016 to March 2017 were enrolled.Mental State Examination (MMSE),Clinical Memory Scale (CMS) test and CT perfusion(CTP) was performed.All patients were divided into memory normal group(n=24,including 1 excellent case,6 above normal cases,and 14 normal cases) and memory impairment group(n =38,including 18 below normal cases,12 periphery cases,8 impaired cases) according to CMS.The ratios of side-to-side period were compared between bilateral mesial temporal lobe and anterior circulation area.The relative time to peak (rTTP),relative mean transit time(rMTY),relative cerebral blood flow(rCBF) and relative cerebral blood volume (rCBV) were calculate.Results The incidence of CTP decompensation in the medial temporal lobe was higher than that in the patients with memory impairment(P＜0.05).The difference of rTTP and rMTT value between the two groups in the bilateral medial temporal lobes was statistically significant (rTFP:(1.131 ±0.037),(1.437±0.139),t=10.520,P＜ 0.05);rMTT:(1.081 ±0.059),(1.281 ±0.174),t=5.423,P＜0.05).Conclusion The patients with VBA severe stenosis are more likely to get memory impairment due to cerebral hypoperfusion.

Reliability and validity of the repeatable battery for the assessment of neuropsychological status in elderly patients with vascular cognitive impairment / 中华老年医学杂志

Objective To evaluate the reliability and validity of the repeatable Battery for the assessment of neuropsychological status (RBANS)in elderly patients with vascular cognitive impairment(VCI).Methods General information and medical history were collected for 102 elderly patients with VCI,and the Mini-Mental State Exam(MMSE)and RBANS were conducted.Eight weeks later,91 of the patients were re-evaluated on RBANS.Data were analyzed for correlation,reliability and validity.Results The RBANS total score was negatively correlated with age(r =-0.464,P＜0.01)and disease course of diabetes (r =-0.387,P ＜ 0.01),and was positively correlated with education level(r=0.510,P＜ 0.01).The internal consistency measure,Cronbach's alpha,for RBANS total scores was 0.87 at an 8 week interval,and the test-retest reliability of single-item scores ranged from 0.61 to 0.77.Moreover,the correlation coefficient between the RBANS total score and the MMSE total score was 0.622.MMSE was correlated with several RBANS indexes,including immediate memory(r =0.672,P＜ 0.05),attention(r=0.612,P＜ 0.05),visual span(r=0.488,P＜ 0.05),delayed memory(r=0.492,P＜ 0.05),and language(r=0.298,P＜ 0.05).Likewise,RBANS was correlated with a number of MMSE categories,such as recall(r=0.473,P＜0.05),calculation(r=0.597,P＜0.05),delayed memory(r =0.489,P＜0.05),command(r=0.351,P＜0.05),reading comprehension(r=0.325,P＜ 0.05),command execution(r=0.511,P＜ 0.01),sentence construction (r =0.303,P ＜ 0.05),and pattern reproduction (r =0.443,P＜0.05).Conclusions The Chinese version of RBANS has good reliability and validity in elderly patients with VCI and can be used as a cognitive measurement tool in these patients.
