Point-of-care hepatitis C screening with direct access referral to improve linkage to care among halfway house residents: a pilot randomised study

INTRODUCTIONLinkage to care among individuals with substance misuse remains a barrier to the elimination of the hepatitis C virus (HCV). We aimed to determine whether point-of-care (PoC) education, screening and staging for liver disease with direct access to hospitals would improve linkage to care among this group.METHODSAll participants were offered PoC education and HCV screening. HCV-positive participants were randomised to standard care (controls) or direct access, which provided a direct pathway to hospitals. Linkage to care was determined by reviewing electronic medical records. Linkage of care cascade was defined as attendance at the specialist clinic, confirmation of viraemia by HCV RNA testing, discussion about HCV treatment and initiation of treatment.RESULTS351 halfway house residents were screened. The overall HCV prevalence was 30.5% (n = 107), with 69 residents in the control group and 38 in the direct access group. The direct access group had a significantly higher percentage of cases linked to specialist review for confirmatory RNA testing (63.2% vs. 40.6%, p = 0.025), HCV treatment discussion (p = 0.009) and treatment initiation (p = 0.01) compared to the controls. Overall, only 12.6% (n = 13) had treatment initiation during follow-up. PoC HCV screening with direct access referral had significantly higher linkage to HCV treatment initiation (adjusted odds ratio 9.13, p = 0.005) in multivariate analysis.CONCLUSIONPoC HCV screening with direct access improves linkage to care and simplifies the HCV care cascade, leading to improved treatment uptake. PoC education, screening, diagnosis and treatment may be an effective strategy to achieving HCV micro-elimination in this population.

民政精神病患者抗精神病药使用时点调查

目的了解我院住院民政精神病患者抗精神病药物使用情况。方法采用自制调查表对我院住院民政精神疾病患者的抗精神病药物使用状况进行时点调查。结果我院住院民政精神病患者在抗精神病药物使用上仍以单一用药为主（78.78%）,其中以氯氮平使用率最高(45.68%),联合用药中均以氯氮平为主要配对方式,而新型非典型抗精神病药使用率极低。结论民政精神病人在抗精神病药物的选择上较为简单,非典型抗精神病药难于被广泛使用,如果能适当选择一些新型抗精神病药,将对提高民政精神病患者的认知,恢复其社会功能起到积极的作用。     

藿砂合剂治疗食管贲门癌根治术后肠功能紊乱33例

食管癌贲门癌根治术后肠功能紊乱,是这类手术后较常见的并发症,其发生率高达54％,常规采用禁食、补液、止泻收敛药物等方法,疗效甚微,我们对这类手术病人常规采取主动给予藿砂合剂治疗,每次30ml,1日3次,术后第5天开始用药,连用4天,取得较满意疗效。临床上凡病人出现舌苔白腻或厚腻,脉象濡或细者,均可预先用药,能减少症状的发生。     

不同刺激量针刺关元穴对寒凝类痛经模型大鼠的影响

目的：观察不同的针刺刺激量施于关元穴对寒凝类痛经模型大鼠子宫组织中收缩素受体（ OTR）及肌球蛋白轻链激酶（ MLCK）含量的影响。方法将处于动情间期3月龄的SD雌性大鼠32只,随机分为盐水组、寒凝类痛经模型组24只,造模成功后将寒凝类痛经模型组又分为模型组、刺激量A组和刺激量B组,每组8只。除盐水组外,模型组、刺激量A组和刺激量B组均采用全身冷冻法结合苯甲酸雌二醇注射法造模。盐水组和模型组不予针刺,刺激量A组予以粗针、深刺、行手法;刺激量B组予以细针、浅刺、不施手法。采用荧光定量PCR方法检测大鼠子宫组织中缩宫素受体（ OTR）的含量。采用ELISA（酶联免疫法）测量大鼠子宫组织中MLCK的含量。结果与盐水组比较,模型组的子宫收缩波个数、波峰峰值、活动度及MLCK水平均升高（ P﹤0.01）;与模型组比较,刺激量A组的子宫收缩波个数明显减少（ P﹤0.05）、MLCK含量明显降低（ P﹤0.01）,刺激量B组的OTR mRNA相对表达量降低（ P﹤0.05）;与刺激量A组比较,刺激量B组收缩波个数增多（ P﹤0.05）、OTR mRNA相对表达量降低（ P﹤0.01）。结论不同刺激量针刺关元穴对寒凝类痛经模型大鼠的效应有所不同,粗针、深刺、行手法的效应较强于细针、浅刺、不行手法的针刺效应,提示针刺的刺激量也是决定针刺疗效的因素之一。

Enhancing the Reliability in the Noninvasive Measurement of the His Bundle Magnetic Field Using a Novel Signal Averaging Methodology

Background: Extraction of the weak electrical activity of the “His Bundle” (HB) by noninvasive methods has not been very successful in the past. The study reassesses the use of signal averaged magnetocardiography (SAMCG), overcoming some of the limitations in earlier studies including in the signal averaging methodology. Methods: SAMCG on healthy subjects (14 male and 1 female) were performed using R‐peak as the fiducial point in all cases and also using QRS‐onset as the fiducial point in select cases. Results: A conspicuous feature (H) with a magnitude up to 200 femto Tesla (fT) attributed to the HB activity was observed in the PR segment at several spatial positions on the thorax, with onset at 35–50 ms before the QRS‐onset (V) in 15 out of 18 trials constituting 83% of cases studied. The QRS‐onset as the fiducial point resolved the feature better compared to the conventionally used R‐peak, especially in trials exhibiting spread in heart rate (HR). This is attributed to the fluctuations in Q_onRD (the time interval between QRS‐onset and R‐peak) compared to the temporal stability of the H‐V duration. Conclusions: SAMCG reveals a well‐resolved H feature. The double hump morphology of the feature extended at least up to a frequency of 150 Hz. The importance of the choice of QRS‐onset as the fiducial point is unequivocally demonstrated, illustrated by measurements on subjects exhibiting considerable heart rate variability. The latter has a general validity and should be applicable to SAECG as well.
