Predictive performance of obesity indexes for the risk of high blood pressure in an adult population

Background and objectives

Comparisons of predictive performance of various anthropometric measures in high blood pressure have not been investigated. This study aimed at evaluating and comparing the predictive power of Body Mass Index (BMI), Body Adiposity index (BAI) and A Body Shape Index (ABSI) for predicting hypertension in adults.

Chronic daily headache in a paediatric headache centre

The prevalence and the clinical features of chronic daily headache (CDH) were studied in 968 children and adolescents observed during a period of one year in the Headache Centre of the Anna Meyer Paediatric Hospital of Florence. Nine hundred and fortyfour patients (97.52%) had primary headache according to ICHD-II, 24 subjects had secondary headache and 56 patients had CDH (5.93% of primary headaches). The mean age of subjects with CDH was higher than general (13.5 vs. 11.5 years), with a female preponderance (69.6% vs. 30.4%). According to the ICHD-II, headaches were classified as chronic migraine in 10 patients (1.5.2 ICHD-II), chronic tension-type headache in 36 (2.3 ICHD-II), new daily persistent headache in 8 (4.8 ICHD-II) and 2 patients reported mixed pattern (chronic migraine+chronic tension type headache). Medication overuse was not implicated in our patients.

Directional sensibility of hairy skin and postural control

People can feel and report the direction of very small movements which cause changes in the tension of the forearm's hairy skin. This subjective sensory function may perhaps reflect more fundamental sensorimotor tasks. The hypothesis was investigated by measuring body sway and movement of six female and male volunteers who were performing the tandem-stance Romberg test with open and closed eyes. The increase in sway and movement after eye closure was reduced significantly when the subjects were allowed to use one forearm to touch a spatially fixed object from below. Three objects were used, a solid Perspex rod, an easily rotating steel ball, and a pointed metal peg whose tip was attached to the skin with a droplet of contact glue. Possible mechanical support could be excluded on basis of the objects' technical properties and the magnitudes of forearm movements. Movement of the forearm relative to an object could provide spatial information about changes of the forearm's position in space. Likewise, changes of skin tension that were caused by such movements could be useful. The Perspex rod and the steel ball might provide both types of information. However, the glued peg only caused changes of skin tension, but reduced sway and movement equally effectively. Therefore, information from tension receptors of the forearm's hairy skin underlying the accurate subjective directional sensibility also appears to participate in basic motor control.     

Effect of perchlorate on calcium release in skinned fibres stimulated by ionic substitution and caffeine

We have determined the effects of the perchlorate ion on the contracture of skinned (sarcolemma removed) skeletal muscle fibres, stimulated either by ionic substitution or caffeine. Calcium release was monitored in single cells by measuring the peak height of tension transients. Perchlorate significantly sensitizes fibres to activation by ionic substitution, a manipulation that is thought to trigger calcium release via the normal physiological pathway. Adding 0.8 mM perchlorate to the solutions shifted the curve relating the magnitude of ionic substitution to the level of activation leftward, such that smaller stimuli were needed to produce a contracture of a given height. Perchlorate could also trigger a contracture directly. Exposing fibres to 1.0 mM perchlorate caused contractures averaging 60% of bracketing controls. In contrast to contractures stimulated by ionic substitution, those triggered by caffeine were unaffected by perchlorate. Since caffeine is thought to act directly on the sarcoplasmic reticulum to cause calcium release, these results suggest that perchlorate enhances activation in skinned fibres by interacting with transverse tubular membranes.     

张力平衡针法改善脑卒中痉挛瘫痪患者残损功能的临床评价

目的:观察张力平衡针法对脑卒中痉挛瘫痪患者残损功能的影响。方法:选择脑卒中痉挛瘫痪患者106例,随机分为张力平衡针法组(54例)、常规针法组(52例)。张力平衡针法组采用张力平衡针法,分别于上、下肢伸肌、屈肌处取穴,常规针法组采用常规针法,穴取肩髃、曲池、外关等,于治疗前后评定患者肌力、肌张力、肌痉挛状态及关节活动度的变化。结果:治疗30天后,张力平衡针法组总有效率为96.3%(52/54),优于常规针法组的84.6%(44/52)(P0.01)。与治疗前比较,两组患者肌力、肌张力评分、肌痉挛状态评分、关节活动度均增加,张力平衡针法组与常规针法组比较改善更显著(均P0.05)。结论:张力平衡针法能显著改善脑卒中痉挛瘫痪患者的肌力、肌张力、肌痉挛状态和增加关节活动度。

Soft tissue tension in extension in total knee arthroplasty affects postoperative knee extension and stability

The purpose of this study was to assess correlation of soft tissue tension in extension with postoperative extension deficit and valgus/varus instability. Sixty-four osteoarthritic knees that underwent primary total knee arthroplasty were investigated. Soft tissue tension in extension was measured during operation with a balancer/tensor device. Extension deficit was measured, and valgus/varus laxity was assessed by stress radiographs in extension and 30°-flexion 1 year after operation. The extension deficit became larger with an increase of soft tissue tension a year after operation. (P < 0.05) The varus laxity in extension and 30°-flexion and valgus laxity in 30°-flexion became smaller with an increase of soft tissue tension (P < 0.05). Our results demonstrated that soft tissue tension during operation affects postoperative knee extension and stability. An erratum to this article can be found at
