Comfort, stability and body posture in wheelchair cushions: a preliminary study with able bodied subjects

Long term wheelchair usage has been related to a number of problems, among which pressure ulcers are one of most concern. The design of wheelchair seat cushions has been of increasing interest among researchers, as it can influence seat interface pressure and user's comfort. The aim of this study was to investigate the subjects' perception comfort, stability and body posture of six different commercially available wheelchair cushions. The evaluation was through a questionnaire, where the subjects rate their perceptions on a ten point visual analog scale after staying seated in the cushion for two minutes. The results shows that the Roho^TM aircell cushion was preferred by the users, while the least preferred one was the water cushion. Individuals' subjective perceptions may compliment objective data on seat interface pressure, thus contributing to a more complete view of the users' experience during wheelchair cushion usage.

Bone defect repair on the alveolar wall of the maxillary sinus using collagen membranes and temporal fascia: an experimental study in monkeys

Few studies has been done using guided bone regeneration in maxillary sinus defects. AIM: To assess the bone repair process in surgical defects on the alveolar wall of the monkey maxillary sinus, which communicates with the sinus cavity, by using collagen membranes: Gen-derm - Genius Baumer, Pro-tape - Proline and autologous temporal fascia. MATERIALS AND METHODS: In this prospective and experimental study, orosinusal communications were performed in four tufted capuchin monkeys (Cebus apella) and histologic analysis was carried out 180 days after. RESULTS: In the defects without a cover (control), bone proliferation predominated in two animals and fibrous connective tissue predominated in the other two. In defects repaired with a temporal fascia flap, fibrous connective tissue predominated in three animals and bone proliferation predominated in one. In the defects repaired with Gen-derm or Pro-tape collagen membranes there was complete bone proliferation in three animals and fibrous connective tissue in one. CONCLUSIONS: Surgical defect can be repaired with both bone tissue and fibrous connective tissue in all study groups; collagen membranes was more beneficial in the bone repair process than temporal fascia or absence of a barrier.

AÇÃO REGULATÓRIA DO GnRH NO DESENVOLVIMENTO EMBRIONÁRIO PRECOCE E VITRIFICAÇÃO DE EMBRIÕES SUÍNOS PELO MÉTODO DE MICROGOTA (ROLE OF GnRH DURING EARLY EMBRYONIC DEVELOPMENT AND DEVELOPMENT OF SWINE EMBRYOS FOLLOWING VITRIFICATION BY MICRODROPLET METHOD)

The objective of this study was to investigate the role of GnRH on the preimplantation development of mouse embryos in vitro. GnRH-I, GnRH-II, and GnRH agonists: Des-Gly, Des-Trp and histrelin did not improve embryo development. However, treatment with the specific GnRH antagonist SB-75 blocked embryo development at morula stage. The inhibition of embryo development by SB-75 could be rescued by the addition of histrelin. To determine which intracellular signaling cascade is involved following binding of GnRH to the GnRHR, embryos were cultured in the presence of specific PKC (GFX) or PKA (SQ22536) inhibitors. The PKC inhibitor blocked embryo development at a similar stage as SB-75, whereas SQ22536 had an inhibitory effect, diminishing blastocyst formation and hatched rates. There are evidences that GnRH has an essential autocrine effect on mouse embryonic development via GnRHR, probably by activating PKC signaling cascade while the inhibition of the GnRH signaling does not activate apoptotic mechanisms involving caspase-3. In another experiment, development in vitro of embryos from Chinese Meishan (M) and occidental white crossbred (WC) females were investigated after improving the vitrification protocol for pig embryos. Efficient cryopreservation of zona pellucida-intact porcine embryos and studies of the difference among breeds could greatly impact the swine industry. The percentage of embryos surviving 24 h after cryopreservation without lysis or degeneration was higher for M (72%) than WC (44%). However, in vitro development of embryos that survived cryopreservation was not different between M and WC at the expanded (64%) or hatched (22%) blastocyst stages. Developmental rates were significantly higher for control embryos than frozen embryos from both breeds at expanded blastocyst stage, but not at hatched blastocyst stage. Rates of expanded blastocyst formation did not differ between M and WC control embryos (98 and 95%, respectively). With a new procedure to warm vitrified pig embryos, the survival rates may be improved. The optimal stages to vitrify pig embryos using the microdroplet method ranges from late compact morula to early expanded blastocyst. The results suggest that M embryos have a higher capacity to survive the vitrification process than WC embryos. O objetivo do presente estudo foi investigar a importância do GnRH no desenvolvimento embrionário precoce em camundongos. GnRH-I, GnRH-II e os GnRH agonistas: Des-Gly, Des-Trp e histrelina não incrementaram o desenvolvimento embrionário. Entretanto, o tratamento com SB-75, um antagonista específico do GnRH, bloqueou o desenvolvimento embrionário no estádio de mórula. A inibição do desenvolvimento embrionário pelo SB-75 pôde ser revertida com a adição de histrelina. Para determinar a cascata do sinal intracelular desencadeada pela ligação do GnRH com o seu receptor, embriões foram cultivados na presença de inibidores específicos da PKC (GFX) e da PKA (SQ22536). O inibidor da PKC bloqueou o desenvolvimento embrionário em estádio similar ao bloqueio mediado pelo SB- 75, enquanto o SQ22536 teve efeito inibitório diminuindo a formação de blastocisto e taxas de eclosão. Os resultados sugerem que o GnRH tem um efeito autócrino essencial no desenvolvimento embrionário através do GnRHR, provavelmente, ativando a cascata da PKC. Por outro lado, a inibição do sinal do GnRH não ativa mecanismos apoptóticos que involvam caspase-3. Em outro experimento, foi investigado o desenvolvimento in vitro de embriões da raça Meishan (M) e branco cruzado (WC) após vitrificação pelo método microgota. O desenvolvimento de protocolos eficientes para criopreservação de embriões suínos com a zona pelúcida intacta e a avaliação das diferenças entre raças pode ter um significativo impacto na suinocultura. A percentagem de embriões que sobreviveram à criopreservação depois de 24 h foi maior na M (72%) do que na WC (44%). No entanto, o desenvolvimento in vitro dos embriões que sobreviveram à criopreservação não foi diferente entre M e WC nos estádios de blastocisto expandido (64%) ou eclodido (22%). Os índices de desenvolvimento foram significativamente mais altos para os embriões controle do que para os embriões vitrificados nas duas raças no estádio de blastocisto expandido, porém não foram diferentes para o estádio de blastocisto eclodido. A formação de blastocisto expandido não diferiu entre os embriões controle M e WC (98 e 95%, respectivamente). Com o novo procedimento (“hot warm”) para descongelar embriões vitrificados pelo método de microgota, pode-se aumentar dos índices de sobrevivência. Os melhores estádios embrionários para a vitrificação de embriões suínos variam de mórula compacta tardia até blastocisto expandido inicial. Os resultados sugerem que embriões M têm mais capacidade de sobreviver ao processo de vitrificação do que embriões WC.

Food Handling Practices, Knowledge and Beliefs of Families with Young Children Based on the Health Belief Model

Objective: To determine current food handling practices, knowledge and beliefs of primary food handlers with children 10 years old and the relationship between these components. Design: Surveys were developed based on FightBac!™ concepts and the Health Belief Model (HBM) construct. Participants: The majority of participants (n= 503) were females (67%), Caucasians (80%), aged between 30 to 49 years old (83%), had one or two children (83%), prepared meals all or most of the time (76%) and consumed meals away from home three times or less per week (66%). Analysis: Descriptive statistics and inferential statistics using Spearman’s rank correlation coefficient (rho) (p<0.05 and one-tail) and Chi-square were used to examine frequency and correlations. Results: Few participants reached the food safety objectives of Healthy People 2010 for safe food handling practices (79%). Mixed results were reported for perceived susceptibility. Only half of the participants (53-54%) reported high perceived severity for their children if they contracted food borne illness. Most participants were confident of their food handling practices for their children (91%) and would change their food handling practices if they or their family members previously experienced food poisoning (79%). Participants’ reasons for high self-efficacy were learning from their family and independently acquiring knowledge and skills from the media, internet or job. The three main barriers to safe food handling were insufficient time, lots of distractions and lack of control of the food handling practices of other people in the household. Participants preferred to use food safety information that is easy to understand, has scientific facts, causes feelings of health-threat and has lots of pictures or visuals. Participants demonstrate high levels of knowledge in certain areas of the FightBac!TM concepts but lacked knowledge in other areas. Knowledge and cues to action were most supportive of the HBM construct, while perceived susceptibility was least supportive of the HBM construct. Conclusion: Most participants demonstrate many areas to improve in their food handling practices, knowledge and beliefs. Adviser: Julie A. Albrecht
