Tecnologia para banho no leito de idosos e usuários acamados: uma contribuição para o cuidar humanizado

This study aimed to validate the technology at Bed Bath System, in view of bedridden elderly and their caregivers, with a view to transforming the conventional paradigm regarding the practice of bodily hygiene held in bath chairs adapted in long-stay institutions for the elderly. This is an experimental study involving 51 (fifty one) elderly and 17 (seventeen) caregivers of three long-stay institutions for the elderly of the city of João Pessoa. For data collection, applied initially to cognitive assessment scale Mini Mental State Examination, with the aim of tracking the subject group of elderly cognitively able to participate in the study. In the second phase, to measure the percentage of agreement and disagreement about the attributes of the subjects of the shower chair and adapted the system for bed bath, used a questionnaire with closed questions, Likert scale model of four (4) points, with a good reliability index (0.728), estimated by alpha conbrach, evidenced by the Wilcoxon test a significant difference (P<0.05) between the responses of seniors and caregivers about the attributes involving technology system in bath bed and bath chair adapted, confirming the perspective of the subjects that the two systems differ significantly. However, the system bed bath got greater degree of agreement for their use, characterizing this system is a technology that makes the differential bed bath pleasurable action, quality and humanized

Desenvolvimento de protótipo de cadeira de banho para indivíduos com paralisia cerebral tetraparética espástica

This study proposes to develop an equipment that attends the demands of tetraplegic people due to cerebral palsy and that promotes an adequate caregivers postural biomechanics during the shower activity of daily living. First, a bibliographic review was performed to define the terms refering to cerebral palsy, activity of daily living (specifically shower), and assistive technology, besides listing the wheelchairs made on the mainly national assistive technology companies. Therefore, this is a descriptive-exploratory study based on a literature review and on a based-field exploration research. On the field research a survey was adopted as a methodological procedure as it is related to a direct investigation related to a phenomenon, on the case, represented by the current shower situation of the people investigated in this study. Data were collected with the application of a form to the caregivers and consumers of the medical-therapeutic treatment and place used by the participants. Such form, which was made up of open and close questions, tried to identify, besides the personal data of evaluated users and consumers, the characteristics of the current shower activity, such as the place where it takes place in the house, the used equipmentS, in the case there is any, and how often it occurs. The form also was used to identify the caregivers and consumers desires and perceptions in relation to the present characteristics of the new dispositive besides the users and consumers anthropometric data. The evaluation of the results obtained through the form, together with the practice and clinical experience of the researchers and engineers involved in this study, made it possible to develop and make up a real shower chair prototype with the specific adjusts destined to adequate the equipment to be used according to the needs of each user and consumer

Tintype of Unidentified African American Woman Leaning on Chair [n.d.]

A small tintype of a young Black woman dressed in white. The date, location and name of the photographer are unknown. This tintype was among the family memorabilia belonging to Iris Sloman Bell, of St. Catharines, Ontario. Relatives of the Sloman - Bell family are descended from former American slaves."Tintypes were the invention of Prof. Hamilton Smith of Ohio. They begin as thin sheets of iron, covered with a layer of black paint. This serves as the base for the same iodized collodion coating and silver nitrate bath used in the ambrotype process. First made in 1856, millions were produced well into the twentieth century. When tintypes were finished in the same sorts of mats and cases used for ambrotypes, it can be almost impossible to distinguish which process was used without removing the image to examine the substrate."

Residual monomer of reline acrylic resins - Effect of water-bath and microwave post-polymerization treatments

Objectives. This study compared the residual monomer (RM) in four hard chair-side reline resins (Duraliner II-D, Kooliner-K, Tokuso Rebase Fast-TRF and Ufi Gel hard-UGH) and one heat-polymerized denture base resin (Lucitone 550-L), which was processed using two polymerization cycles (short-LS and long-LL). It was also investigated the effect of two after polymerization treatments on this RM content.Methods. Specimens (n = 18) of each material were produced following the manufacturers' instructions and then divided into three groups. Group I specimens were left untreated (GI-control). Specimens of group II (GII) were given post-polymerization treatment by microwave irradiation. In group III (GIII), specimens were submitted to immersion in water at 55 degrees C (reline resins-10 min; denture base resin L-60min). The RM was analyzed using high performance liquid chromatography (HPLC) and expressed as a percentage of RM. Data were analyzed by two-way ANOVA followed by Tukey's test (alpha = 0.05).Results. Comparing control specimens, statistical differences were found among all materials (p < 0.05), and the results can be arranged as K (1.52%) > D (0.85%) > UGH (0.45%) > LL (0.24%) > TRF (0.14%) > LS (0.08%). Immersion in hot water (GIII) promoted a significant (p < 0.05) reduction in the RM for all materials evaluated compared to control (GI), with the exception of LL specimens. Materials K, UGH and TRF exhibited significantly (p < 0.05) lower values of RM after microwave irradiation (GII) than in the control specimens.Significance. The reduction in RM promoted by water-bath and microwave post-polymerization treatments could improve the mechanical properties and biocompatibility of the relining and denture base materials.

Ethanol-induced vasoconstriction is mediated via redox-sensitive cyclo-oxygenase-dependent mechanisms

The present study investigated the role of ROS (reactive oxygen species) and COX (cyclooxygenase) in ethanol-induced contraction and elevation of [Ca(2+)](i) (intracellular [Ca(2+)]). Vascular reactivity experiments, using standard muscle bath procedures, showed that ethanol (1-800 mmol/l) induced contraction in endothelium-intact (EC(50): 306 +/- 34 mmol/l) and endothelium-denuded (EC(50): 180 +/- 40 mmol/l) rat aortic rings. Endothelial removal enhanced ethanol-induced contraction. Preincubation of intact rings with L-NAME [N(G)-nitro-L-arginine methyl ester; non-selective NOS (NO synthase) inhibitor, 100 mu mol/l], 7-nitroindazole [selective nNOS (neuronal NOS) inhibitor, 100 mu mol/l], oxyhaemoglobin (NO scavenger, 10 mu mol/l) and ODQ (selective inhibitor of guanylate cyclase enzyme, 1 mu mol/l) increased ethanol-induced contraction. Tiron [O(2)(-) (superoxide anion) scavenger, 1 mmol/l] and catalase (H(2)O(2) scavenger, 300 units/ml) reduced ethanol-induced contraction to a similar extent in both endothelium-intact and denuded rings. Similarly, indomethacin (non-selective COX inhibitor, 10 mu mol/l), SC560 (selective COX- I inhibitor, 1 mu mol/l), AH6809 [PGF(2 alpha) (prostaglandin F(2 alpha))] receptor antagonist, 10 mu mol/l] or SQ29584 [PGH(2)(prostaglandin H(2))/TXA(2) (thromboxane A(2)) receptor antagonist, 3 mu mol/l] inhibited ethanol-induced contraction in aortic rings with and without intact endothelium. In cultured aortic VSMCs (vascular smooth muscle cells), ethanol stimulated generation of O(2)(-) and H(2)O(2). Ethanol induced a transient increase in [Ca(2+)](i), which was significantly inhibited in VSMCs pre-exposed to tiron or indomethacin. Our data suggest that ethanol induces vasoconstriction via redox-sensitive and COX-dependent pathways, probably through direct effects on ROS production and Ca(2+) signalling. These findings identify putative molecular mechanisms whereby ethanol, at high concentrations, influences vascular reactivity. Whether similar phenomena occur in vivo at lower concentrations of ethanol remains unclear.

Study of copper electrodeposition mechanism from a strike alkaline bath prepared with 1-hydroxyethane-1,1-diphosphonic acid through cyclic voltammetry technique

Copper strike baths are extensively used in metal plating industry as they present the ability to plate adherent copper layers on less-noble metal substrates such as steel and zinc die castings. However, in the last few years, due to environmental controls and safety policies for operators, the plating industry has been interested in replacing the toxic cyanide copper strike baths with environmentally friendly baths. A broad bibliographic review showed that the published papers, referring to the new nontoxic copper strike baths, are patents, having little or no emphasis focused on electrodeposition mechanisms. Therefore, it was decided to study the copper electrodeposition mechanism from a strike alkaline bath prepared with one of the most nontoxic chelating agents cited in many patents which is the 1-hydroxyethane-1,1-diphosphonic acid, known as HEDP. This acid forms very stable water soluble complexes with Cu(2+) ions, thus cupric sulfate was used for preparing the plating bath. The results obtained through a cyclic voltammetry technique showed that Cu(2+) ion reduction to Cu from an HEDP electrodeposition bath occurs via a direct reduction reaction without a formation of Cu(+) intermediates.
