Selected AbstractsMyofascial Trigger Points, Neck Mobility, and Forward Head Posture in Episodic Tension-Type HeadacheHEADACHE, Issue 5 2007César Fernández-de-las-Peñas PT Objective.,To assess the differences in the presence of trigger points (TrPs) in head and neck muscles, forward head posture (FHP) and neck mobility between episodic tension-type headache (ETTH) subjects and healthy controls. In addition, we assess the relationship between these muscle TrPs, FHP, neck mobility, and several clinical variables concerning the intensity and the temporal profile of headache. Background.,TTH is a headache in which musculoskeletal disorders of the craniocervical region might play an important role in its pathogenesis. Design.,A blinded, controlled pilot study. Methods.,Fifteen ETTH subjects and 15 matched controls without headache were studied. TrPs in both upper trapezius, both sternocleidomastoids, and both temporalis muscles were identified according to Simons and Gerwin diagnostic criteria (tenderness in a hypersensible spot within a palpable taut band, local twitch response elicited by snapping palpation, and elicited referred pain with palpation). Side-view pictures of each subject were taken in both sitting and standing positions, in order to assess FHP by measuring the craniovertebral angle. A cervical goniometer was employed to measure neck mobility. All measures were taken by a blinded assessor. A headache diary was kept for 4 weeks in order to assess headache intensity, frequency, and duration. Results.,The mean number of TrPs for each ETTH subject was 3.7 (SD: 1.3), of which 1.9 (SD: 0.9) were active, and 1.8 (SD: 0.9) were latent. Control subjects only had latent TrPs (mean: 1.5; SD: 1). TrP occurrence between the 2 groups was significantly different for active TrPs (P < .001), but not for latent TrPs (P > .05). Differences in the distribution of TrPs were significant for the right upper trapezius muscles (P= .04), the left sternocleidomastoid (P= .03), and both temporalis muscles (P < .001). Within the ETTH group, headache intensity, frequency, and duration outcomes did not differ depending on TrP activity, whether the TrP was active or latent. The craniovertebral angle was smaller, ie, there was a greater FHP, in ETTH patients than in healthy controls for both sitting and standing positions (P < .05). ETTH subjects with active TrPs in the analyzed muscles had a greater FHP than those with latent TrPs in both sitting and standing positions, though differences were only significant for certain muscles. Finally, ETTH patients also showed lesser neck mobility than healthy controls in the total range of motion as well as in half-cycles (except for cervical extension), although neck mobility did not seem to influence headache parameters. Conclusions.,Active TrPs in the upper trapezius, sternocleidomastoid, and temporalis muscles were more common in ETTH subjects than in healthy controls, although TrP activity was not related to any clinical variable concerning the intensity and the temporal profile of headache. ETTH patients showed greater FHP and lesser neck mobility than healthy controls, although both disorders were not correlated with headache parameters. [source] Process evaluation of two environmental nutrition programmes and an educational nutrition programme conducted at supermarkets and worksite cafeterias in the NetherlandsJOURNAL OF HUMAN NUTRITION & DIETETICS, Issue 2 2004I. Steenhuis Abstract Introduction This article describes the process evaluation of two environmental programmes and an educational nutrition programme, implemented at supermarkets and worksite cafeterias. Studies conducted earlier, indicated that the programmes had no effect on consumers' eating behaviour. Consequently, the more specific purpose of the present study was to identify explanations for the ineffectiveness of the programmes and to formulate recommendations for future programmes. Materials and methods The environmental programmes included labelling of healthy products and increasing the range of healthy foods on offer. The education programme consisted of several elements, such as brochures and a self-help guide. Semi-structured interviews were conducted with 21 managers of supermarkets and worksite cafeterias where the programmes were implemented. Results Although materials were not always entirely compatible with the different supermarkets and worksite cafeterias, the degree of implementation was satisfactory. According to the managers, the programmes were not striking enough, the labelling would have been more effective if it had discriminated between different brands of a product, and the number of new products was too small compared with the total range of foods on offer. Conclusions The findings suggest that programmes should be promoted intensively. Furthermore, the relevant manufacturers and wholesalers supplying worksite cafeterias should be encouraged to increase their range of suitable low-fat products. Finally, the feasibility and possible effects of brand-specific labelling should be investigated further.

A total of 203 individuals were identified. The number of newly identified individuals barely increased after the first 1.5 yr. The identified individuals in one season were frequently resighted with percentages of mostly over 60% during the subsequent seasons. Most of the dolphins off Amakusa were yearround residents, although the total range of their habitat was unknown. The population size estimated by the mark-recapture technique was 218 individuals with a CV of 5.41% in 1995,1997. The group commonly consisted of more than 100 individuals. The large group size was thought to be a response to feeding on schooling fishes. [source] The pattern of intravenous drug administration during the transfer of critically ill children by a specialist transport teamPEDIATRIC ANESTHESIA, Issue 10 2006AGNI S. SAHA MD Summary Background:, There are few published data on the patterns of intravenous drug administration by specialist pediatric intensive care unit (PICU) transport teams during the transfer of critically ill children between hospitals. Methods:, A retrospective review of retrieval documentation was undertaken for all patients transported by the Royal Manchester Children's Hospital PICU transport team over a period of 1 year. Results:, A total of 257 patients were transported during the study period, 82 patients (32%) were excluded owing to incomplete or absent documentation, leaving a sample of 175 available for analysis. Intravenous drugs were administered to 168 of these patients (96%). In total, 38 different drugs were administered. The four most commonly administered drugs were midazolam (130 patients), morphine (129 patients), atracurium (108 patients), and heparin (53 patients). Ten drugs accounted for 90% of all prescription episodes (total number of infusions and bolus doses administered), whilst 16 drugs were prescribed only once. The mean number of drugs administered per patient was 3.25 with a mean of 1.96 drug infusions and 1.29 bolus drugs administered per patient. Conclusions:, A relatively small number of drugs are used frequently during the retrieval of critically ill children, but the total range of drugs that are used is large. This has implications for the rational carriage of drugs by PICU transport teams, the potential for drug errors and also for the development of advanced nurse practitioners whose prescribing-like activities may depend on the development of Patient Group Directions. [source] Climate and Growth Form: The Consequences for Genome Size in PlantsPLANT BIOLOGY, Issue 5 2005D. Ohri Abstract: The adaptive significance of nuclear DNA variation in angiosperms is still widely debated. The discussion mainly revolves round the causative factors influencing genome size and the adaptive consequences to an organism according to its growth form and environmental conditions. Nuclear DNA values are now known for 3874 angiosperm species (including 773 woody species) from over 219 families (out of a total of 500) and 181 species of woody gymnosperms, representing all the families. Therefore, comparisons have been made on not only angiosperms, taken as a whole, but also on the subsets of data based on taxonomic groups, growth forms, and environment. Nuclear DNA amounts in woody angiosperms are restricted to less than 23.54 % of the total range of herbaceous angiosperms; this range is further reduced to 6.8 % when woody and herbaceous species of temperate angiosperms are compared. Similarly, the tropical woody dicots are restricted to less than 50.5 % of the total range of tropical herbaceous dicots, while temperate woody dicots are restricted to less than 10.96 % of the total range of temperate herbaceous dicots. In the family Fabaceae woody species account for less than 14.1 % of herbaceous species. Therefore, in the total angiosperm sample and in subsets of data, woody growth form is characterized by a smaller genome size compared with the herbaceous growth form. Comparisons between angiosperm species growing in tropical and temperate regions show highly significant differences in DNA amount and genome size in the total angiosperm sample. However, when only herbaceous angiosperms were considered, significant differences were obtained in DNA amount, while genome size showed a non-significant difference. An atypical result was obtained in the case of woody angiosperms where mean DNA amount of tropical species was almost 25.04 % higher than that of temperate species, which is because of the inclusion of 85 species of woody monocots in the tropical sample. The difference becomes insignificant when genome size is compared. Comparison of tropical and temperate species among dicots and monocots and herbaceous monocots taken separately showed significant differences both in DNA amount and genome size. In herbaceous dicots, while DNA amount showed significant differences the genome size varies insignificantly. There was a non-significant difference among tropical and temperate woody dicots. In three families, i.e., Poaceae, Asteraceae, and Fabaceae the temperate species have significantly higher DNA amount and genome size than the tropical ones. Woody gymnosperms had significantly more DNA amount and genome size than woody angiosperms, woody eudicots, and woody monocots. Woody monocots also had significantly more DNA amount and genome size than woody eudicots. Lastly, there was no significant difference between deciduous and evergreen hardwoods. The significance of these results in relation to present knowledge on the evolution of genome size is discussed. [source] | |||||||||||||
