Adherence to the dialysis prescription: partnering with patients for improved outcomes.

Nonadherence is common in the U.S. dialysis population. No single strategy has been definitely proven to yield universal and/or lasting improvements in adherence. However, using a patient-centered approach, including the removal of barriers to adherence, ongoing education, and cognitive behavioral strategies, may generate increased opportunities for patients and the nephrology staff to improve both adherence and outcomes.     

颅内脑池显微解剖研究

目的通过对国人脑池显微解剖的研究,以指导显微神经外科手术和进一步理解影像学解剖的重要临床意义和应用价值。方法对15具经福尔马林固定的国人成年头颅标本的颅内各个脑池进行显微解剖研究,测量和描述各脑池的位置、大小、形态及结构。结果颅内重要的脑池有(1)嗅池:长度为(32.68±2.97)mm,宽度为(7.18±1.82)mm,深度为(7.20±1.27)mm;(2)视交叉池:侧壁长度为(14.88±3.07)mm,上表面前壁长(14.20±1.47)mm,后壁长(10.37±1.59)mm;(3)颈内动脉池:长度为(15.06±3.07)mm,宽度为(12.01±1.32)mm;(4)终板池:底边左侧长度为(8.99±1.15)mm,右侧长度为(21.00±1.09)mm,最大宽径为(16.42±2.58)mm;(5)脚间池:最大深度为(19.47±2.28)mm,池顶宽度为(11.35±2.85)mm;(6)脚池:为三角形,三边长度分别为(10.48±2.56)mm,(9.64±1.78)mm,(3.58±0.25)mm;(7)外侧裂池:上部长度为(18.63±2.02)mm,基底部长度为(38.08±3.22)mm,宽度为(5.65±0.92)mm,深度为(7.02±2.28)mm;(8)胼胝体池:平均最大宽径为(3.44±0.40)mm;(9)四叠体池:最大长径为(19.37±3.38)mm,最大宽径为(15.24±2.37)mm,最大前后径为(3.65±0.57)mm;(10)环池:为环形,最大宽度为(3.16±0.37)mm;(11)小脑延髓池:最大长度为(18.77±1.77)mm,最大宽度为(32.4     

Monocular preferences in binocular viewing.

Faced with an unobstructed view, both foveas can be readily aligned with a distant visual target. The minor difference in the view of the two eyes (which arises from slightly different lines of sight) presents no special problem and is, indeed, the basis of stereopsis. However, when obstructing objects are present in the foreground, the view provided by one eye becomes wholly or partially incompatible with the view of the other. We have investigated how we cope with this everyday situation by having volunteers observe distant targets through a fenestrated screen. In this circumstance, subjects naturally position themselves to view a target of interest with one eye--usually the right eye. This monocular habit in normal viewing reinforces other evidence for the unorthodox idea that visual perception arises from a union in consciousness of monocular images that are elaborated independently.
