Streptokinase versus alteplase and other treatments for acute and delayed thrombolysis of blood stains in clothing.
(17/323)
OBJECTIVE: To assess the usefulness of heparin, alteplase, and streptokinase in removing blood stains. DESIGN: Randomised controlled trial. SETTING: Hospital laundry. INTERVENTIONS: Blood stains were allocated to treatment with alteplase, streptokinase, heparin, a commercial enzymatic stain remover, or no treatment at all after three or seven hours and then washed in hot or cold water two hours later. RESULTS: Both hot water and early treatment were strongly associated with improved stain removal. All four treatments were associated with a worse outcome than no treatment at all, although for streptokinase this trend did not reach significance. The commercial stain remover gave the worst results of all treatments tested. CONCLUSIONS: Contrary to popular wisdom, hot water is much more effective than cold in removing blood stains. Methodologically rigorous research and evidence based principles are needed within the laundry industry, and the role of thrombolytic drugs should be assessed further. (+info)
Japanese and Korean female students' evaluation of elderly people's clothing colors.
(18/323)
This study evaluated the clothing colors in the elderly. We took photos using the elderly as models, displayed them on a computer screen, and produced 75 colors of the clothing in the elderly using computer graphics. The 75 colors were evaluated by Japanese and Korean female students. We compared the ideal colors for and the colors actually worn by elderly people in Japan and Korea. Korean students tended to evaluate high value colors positively, while Japanese students tended to evaluate low value colors positively. When asked to choose the ideal clothing color for elderly people, the choices differed between the Korean student group and the Japanese student group. The images held concerning these colors also differed between the two groups. When selecting the ideal color to be worn by elderly people, Japanese students attached importance to taste, brilliance, functionality and comfort. On the other hand, Korean students attached importance to commonness and inactivity when selecting the ideal clothing color for elderly people. Thus, in the present study, the evaluation of the clothing colors for elderly people differed between Japanese and Korean students. (+info)
Japanese and Korean elderly people's evaluation of clothing colors for elderly people.
(19/323)
This study evaluated the clothing colors in the elderly. We took photos using the elderly as models, displayed them on a computer screen, and produced 75 colors of the clothing in the elderly using computer graphics. The 75 colors were evaluated by Japanese and Korean elderly women. We compared the ideal colors for and the colors actually worn by elderly people in Japan and Korea. Japanese and Korean elderly women differed concerning their ideal clothing color and their most often worn color. The images concerning clothing colors also differed between the two groups, suggesting differences in their views related to clothing. Japanese elderly women tended to view clothing as a means of expressing their individuality, while Korean elderly women tended to view clothing as a means of expressing their character. (+info)
Ornaments of the earliest Upper Paleolithic: new insights from the Levant.
(20/323)
Two sites located on the northern Levantine coast, Ucagizli Cave (Turkey) and Ksar 'Akil (Lebanon) have yielded numerous marine shell beads in association with early Upper Paleolithic stone tools. Accelerator mass spectrometry (AMS) radiocarbon dates indicate ages between 39,000 and 41,000 radiocarbon years (roughly 41,000-43,000 calendar years) for the oldest ornament-bearing levels in Ucagizli Cave. Based on stratigraphic evidence, the earliest shell beads from Ksar 'Akil may be even older. These artifacts provide some of the earliest evidence for traditions of personal ornament manufacture by Upper Paleolithic humans in western Asia, comparable in age to similar objects from Eastern Europe and Africa. The new data show that the initial appearance of Upper Paleolithic ornament technologies was essentially simultaneous on three continents. The early appearance and proliferation of ornament technologies appears to have been contingent on variable demographic or social conditions. (+info)
Assessment of dry heat exchanges in newborns: influence of body position and clothing in SIDS.
(21/323)
A dramatic decrease of sudden infant death syndrome (SIDS) has been noted following the issuance of recommendations to adopt the supine sleeping position for infants. It has been suggested that the increased risk could be related to heat stress associated with body position. In the present study, the dry heat losses of small-for-gestational-age newborns nude or clothed were assessed and compared to see whether there is a difference in the ability to lose heat between the prone and supine positions. An anthropomorphic thermal mannequin was exposed to six environmental temperatures, ranging between 25 and 37 degrees C, in a single-walled, air-heated incubator. The magnitudes of heat losses did not significantly differ between the two body positions for the nude (supine 103.46 +/- 29.67 vs. prone 85.78 +/- 34.91 W/m(2)) and clothed mannequin (supine 59.35 +/- 21.51 vs. prone 63.17 +/- 23.06 W/m(2)). With regard to dry heat exchanges recorded under steady-state conditions, the results show that there is no association between body position and body overheating. (+info)
Vitamin D deficiency and insufficiency in Orthodox and non-Orthodox Jewish mothers in Israel.
(22/323)
BACKGROUND: The modest clothing that Orthodox Jewish women wear exposes very little of their skin to sunlight. Under these conditions they may develop vitamin D deficiency, even in sunny Israel. OBJECTIVES: To determine and compare the vitamin D nutritional status in Jewish orthodox mothers to that of non-orthodox mothers who live in the same metropolitan area in Israel. METHODS: 25-Hydroxyvitamin D was measured by competitive protein-binding radioassay in the sera of 341 Jewish Israeli mothers (156 orthodox and 185 non-orthodox). The sera were obtained 48-72 hours after childbirth during the late summer of 1998 and the spring of 1999. RESULTS: The mean (SD) serum concentration of 25-OHD was significantly (P < 0.002) lower (13.5 +/- 7.5 ng/ml) in the orthodox than in the non-orthodox mothers (18.6 +/- 9.6 ng/ml). Vitamin D deficiency (< 5 ng/ml) and insufficiency (< 10 ng/ml) were more common in the orthodox mothers (5.1% and 32.7% respectively) than in the non-orthodox mothers (2.7% and 13%, respectively). In subgroups of mothers supplemented with 400 units of vitamin D daily during pregnancy, vitamin D deficiency and insufficiency were less common (2.2% and 13%, respectively) in orthodox and non-orthodox mothers (0% and 8.1%, respectively). Vitamin D insufficiency was more common in the winter than in the summer only among non-orthodox mothers. CONCLUSIONS: The high prevalence of vitamin D deficiency and insufficiency in Israeli mothers raises the question whether vitamin D supplements should be given to pregnant women in Israel, at least to orthodox mothers.

Attractiveness of black Shannon trap for phlebotomines.
(23/323)
A white Shannon-type trap was used for captures of female sand flies in the search for natural infection with flagellates, however, due to its low productivity and as a large number of phlebotomines settled on the researchers' black clothes, we decided to compare the relative attractiveness of black and white Shannon-type traps for sand flies. Several pairs of black and white traps were placed side by side in front of caves in four areas in the Serra da Bodoquena, Bonito county, State of Mato Grosso do Sul, Brazil, for a total of 12 observations and 44 h of capture. The experiment resulted in 889 phlebotomines captured, 801 on the black and 88 on the white trap, representing 13 species. The hourly Williams' means were 8.67 and 1.24, respectively, and the black/white ratio was 7.0:1.0. Lutzomyia almerioi, an anthropophilic species closely associated with caves, was predominant (89%). Only two other species, Nyssomyia whitmani and Psathyromyia punctigeniculata, also anthropophilic, were significantly attracted to the black rather than to the white trap (chi(2) test; p < or = 0.01). The difference between the diversity index of the two traps was not significant at level 0.05. The black trap in these circumstances was much more productive than the white, especially for anthropophilic species. (+info)
Survival of some medically important fungi on hospital fabrics and plastics.
(24/323)
Tests of the survival of Candida spp., Aspergillus spp., a Fusarium sp., a Mucor sp., and a Paecilomyces sp. on hospital fabrics and plastics indicated that viability was variable, with most fungi surviving at least 1 day but many living for weeks. These findings reinforce the need for appropriate disinfection and conscientious contact control precautions. (+info)
