单位:日本东京市新宿区。目的:通过对新宿区的结核分枝杆菌的传染状况的评估,以便有效合理地分配卫生资源,从而成功地实施结核控制规划。设计:将结核分枝杆菌的基因型资料和结核患者资料结合起来的观察描述性研究。结果:男性、年龄小于40岁的患者和无家可归者的基因型成簇率显著较高,他们的调整比值比和95%可信区间分别是(aOR 1.94,95%CI 1.04—3.65,P=0.038),(aOR 2.09,95%CI 1.17—3.71,P=0.012),(aOR 2.72,95%CI 1.42—5.20,P=0.002),而国外出生患者的基因型成簇率却较低(aOR 0.21,95%CI 0.06—0.76,P= 0.017)。在152例结核患者的45个基因型簇中, 102(67.1%)例患者的26个簇是由无家可归者和非无家可归混合而成,其中一个混合簇包括1个在日本出生的8个月的婴儿。结论:此研究显示结核分枝杆菌在无家可归人群的传播要比在非无家可归人群中更常发生。然而,偶然的接触也会引起结核分枝杆菌在无家可归者和普通人群之间的传播。

Recently, reconsidering the Rastall idea T_(μ;νν)^(v)=α_(,μ) through relativistic thermodynamics gives a new form for the scalar field α which led us to construct modern modified theory of gravity debugged ‘non-conserved gravity theory’ Fazlollahi 2023 Euro. Phys. J. C 83 923. This theory unlike other modified theories of gravity cannot directly explain the current acceleration expansion in the absence of the cosmological constant and or existence of other forms of dark energy. hence, in this study we have reinvestigated holographic dark energy Ρ_(X)~h^(2) in the non-conserved theory of gravity. In this context, the density and pressure of dark energy depend on the non-conserved term and density of the dust matter field. As shown, due to non-conservation effects on large-scale structures, unlike the original holographic model, our model onsets an acceleration epoch for the current Universe satisfies observations. Moreover, the interaction and viscous scenarios are studied for this model.
