Distinct Possibility (distinct + possibility)
Selected AbstractsA Dialogue on the Future of Nursing PracticeINTERNATIONAL JOURNAL OF NURSING TERMINOLOGIES AND CLASSIFICATION, Issue 3 2007APRN-BC, Mary Ann Lavin ScD PURPOSE.,The challenges of health care; its safety, effectiveness, and efficiency; the quality of care; and the outcomes patients experience are issues central to nursing practice. This centrality needs to be affirmed as the profession shapes its practice over the next 50 years. The purpose of this article is to initiate a dialogue on the future of nursing practice. METHODS.,The methods used are observation, reflection, dialogue, and proposed actions. FINDINGS.,The results of this process are preliminary. They suggest that the establishment of nursing hospitals is a distinct possibility. CONCLUSIONS.,This article concludes with a series of arguments for and against this position along with an invitation for your participation in this dialogue. NURSING IMPLICATIONS.,The major implications of this article are not "nursing" implications per se but client and patient implications and the future contribution of nursing to improved health and patient care. [source] Are Nonresorbing Osteoclasts Sources of Bone Anabolic Activity?,JOURNAL OF BONE AND MINERAL RESEARCH, Issue 4 2007Morten A Karsdal PhD Abstract Some osteopetrotic mutations lead to low resorption, increased numbers of osteoclasts, and increased bone formation, whereas other osteopetrotic mutations lead to low resorption, low numbers of osteoclasts, and decreased bone formation. Elaborating on these findings, we discuss the possibility that osteoclasts are the source of anabolic signals for osteoblasts. In normal healthy individuals, bone formation is coupled to bone resorption in a tight equilibrium. When this delicate balance is disturbed, the net result is pathological situations, such as osteopetrosis or osteoporosis. Human osteopetrosis, caused by mutations in proteins involved in the acidification of the resorption lacuna (ClC-7 or the a3-V-ATPase), is characterized by decreased resorption in face of normal or even increased bone formation. Mouse mutations leading to ablation of osteoclasts (e.g., loss of macrophage-colony stimulating factor [M-CSF] or c- fos) lead to secondary negative effects on bone formation, in contrast to mutations where bone resorption is abrogated with sustained osteoclast numbers, such as the c-src mice. These data indicate a central role for osteoclasts, and not necessarily their resorptive activity, in the control of bone formation. In this review, we consider the balance between bone resorption and bone formation, reviewing novel data that have shown that this principle is more complex than originally thought. We highlight the distinct possibility that osteoclast function can be divided into two more or less separate functions, namely bone resorption and stimulation of bone formation. Finally, we describe the likely possibility that bone resorption can be attenuated pharmacologically without the undesirable reduction in bone formation. [source] Prevalence, whole genome characterization and phylogenetic analysis of hepatitis B virus in captive orangutan and gibbonJOURNAL OF MEDICAL PRIMATOLOGY, Issue 6 2008Pattaratida Sa-nguanmoo Abstract Background, Hepatitis B virus (HBV) is a public health problem worldwide and apart from infecting humans, HBV has been found in non-human primates. Methods, We subjected 93 non-human primates comprising 12 species to ELISA screening for the serological markers HBsAg, antiHBs and antiHBc. Subsequently, we detected HBV DNA, sequenced the whole HBV genome and performed phylogenetic analysis. Results, HBV infection was detected in gibbon (4/15) and orangutan (7/53). HBV DNA isolates from two gibbons and seven orangutans were chosen for complete genome amplification. We aligned the Pre-S/S, Pre-C/C and entire genomes with HBV sequences and performed phylogenetic analysis. The gibbon and orangutan viruses clustered within their respective groups. Conclusions, Both geographic location and host species influence which HBV variants are found in gibbons and orangutans. Hence, HBV transmission between humans and non-human primates might be a distinct possibility and additional studies will be required to further investigate this potential risk. [source] Rich Countries, Poor People?NEW PERSPECTIVES QUARTERLY, Issue 1 2007JOSEPH STIGLITZ Globalization may yet repeal the Biblical adage that the poor will always be with us. But for now there are enough losers to go along with the winners that a slide back toward fragmentation and protectionism is a distinct possibility, as was also the case at the turn of the 20th century. Our contributors in this section offer their advice on how to make globalization work for everyone. [source] Postnatal peer counselling on exclusive breastfeeding of low-birthweight infants: A randomized, controlled trialACTA PAEDIATRICA, Issue 8 2005Grace V Agrasada Abstract Aim: Exclusive breastfeeding increases survival and optimizes growth of low-birthweight (LBW) infants. If supported, mothers can overcome the unique difficulties associated with breastfeeding from birth to 6 mo. We tested the efficacy of postnatal peer counselling among first-time mothers that aimed to increase exclusive breastfeeding of term LBW infants. Methods: In a Manila hospital, 204 mothers were randomized into three groups. Two intervention groups receiving home-based counselling visits, one by counsellors trained in breastfeeding counselling (n=68), the other by counsellors trained in general childcare (n=67), were compared with a control group of mothers (n=69) who did not receive counselling. Results: Eighty-eight per cent of the participating pairs completed the trial. At 6 mo, 44% of the breastfeeding counselled mothers, 7% childcare-counselled mothers and none of the mothers in the control group were exclusively breastfeeding. More mothers in the breastfeeding counselled group than in the other groups were still breastfeeding at 6 mo. Twenty-four infants who were exclusively breastfed for 6 mo did not have any diarrhoea. All groups had improved mean weight-for-age Z-scores at 6 mo. Conclusion: This study has provided fundamental evidence of successful intervention to achieve 6 mo of exclusive breastfeeding among term LBW infants. By improving health outcomes, enhanced breastfeeding offers a distinct possibility of disrupting the intergenerational cycle of undernourished women giving birth to LBW infants. [source] | ||||||||||
