ABSTRACT Maturing Atlantic mackerel with and without artificial feeding, kept in sea pens (September to May), showed differences in digestive efficiency (protease activity ratio of trypsin to chymotrypsin), muscle growth (concentrations of RNA, protein, RNA/protein ratio and free amino acids [FAA]) and oocyte quality (trypsin-like specific activity, and concentrations of RNA, RNA/protein ratio and FAA). The artificially fed mackerel had higher body weights (1.7 times) but with less white muscle protein concentration (0.5 time), compared to the control group. Both groups showed higher levels of capacity for protein synthesis in the oocytes than in the white muscle, but it was about two times higher in the artificially fed fish whereas about four times higher in the control group. This indicated that, during maturation, development of oocytes and muscle for growth occurred concurrently in higher growth mackerel, while development of oocytes dominated in slower growth fish. A higher trypsin-like specific activity with higher FAA levels in the oocytes from females fed with an artificial diet, compared to the control group, suggested differences in development and quality between the gametes of the fish with different feedings. PRACTICAL APPLICATIONS The work illustrates differences in digestive efficiency and the quality of growth performance (growth and protein metabolism in muscle and oocytes) in fish with different feedings. The use of various methods for evaluating digestive efficiency and the quality of fish growth performance could provide reasonable information for some important biological differences between fish groups, especially when the number of samples are low. It is more advantageous to apply different methods simultaneously than using growth parameter alone in order to study for precise evaluation of the quality of fish growth performance. The methods are very practical for studying food utilization and growth quality of fish in different environmental conditions and with different behaviors in aquaculture as well as in natural ecosystem where food consumption rate and feeding regime cannot be under control.

The Late Prehistoric,Early Historic Game Sink in the Northwestern United States

CONSERVATION BIOLOGY, Issue 1 2002
R. Lee Lyman
The number of big game killed by the Corps of Discovery in 1805,1806 and recorded by Lewis and Clark suggests that ungulates were abundant in central and eastern Montana and rare in western Montana, central Idaho, and southeastern Washington during the early nineteenth century. Paleoecologists Paul Martin and Chris Szuter conclude that this difference was a function of human predation. They support their conclusion that ungulates would have been abundant in southeastern Washington had humans not hunted them by arguing that the nineteenth-century livestock industry was successful without supplemental feeding. The livestock industry was, however, not consistently successful until artificial feeding was initiated. Archaeological data from eastern Washington indicate that ungulates have been taken by human hunters more frequently than small-mammal prey throughout the last 10,000 years and that ungulates decreased relative to small mammals coincident with changes in climate. Bison ( Bison bison) and elk (Cervus canadensis) were present in eastern Washington throughout the Holocene, but bison were abundant there only during a cooler and moister period; elk have been abundant only in the twentieth century, subsequent to transplants and the extermination of predators. Geographic variation in the abundance of bison across Montana, Idaho, and eastern Washington has been influenced by human predation but has also been influenced by biogeographic history, habitat differences, and climatic change. Resumen: Los datos históricos proveen información valiosa sobre las estructuras de los ecosistemas, sus funciones y procesos. El número de animales de caza grandes que fueron sacrificados por las tropas de descubrimiento en 1805-1806 y registradas por Lewis y Clark sugieren que los ungulados eran abundantes en Montana central y oriental y raros en Montana occidental, Idaho central y el sudeste de Washington durante los inicios del siglo diecinueve. Los paleontólogos Paul Martin y Chris Szuter concluyen que esta diferencia fue causada por la depredación humana. Ellos apoyan su conclusión de que los ungulados podrían haber sido abundantes en el sudeste de Washington si los humanos no los hubieran cazado argumentando que la industria de la ganadería del siglo diecinueve exitosa sin alimento suplementario. Sin embargo, la industria de la ganadería no fue consistentemente exitosa hasta que se inició la alimentación artificial. Los datos arqueológicos de Washington oriental indican que los ungulados fueron eliminados por los cazadores humanos mas frecuentemente que las presas pequeñas de mamíferos a lo largo de los últimos 10,000 años y que la disminución de ungulados, relativa a la de mamíferos pequeños coincidió con cambios en el clima. El bisonte (Bison bison) y el alce (Cervus canadiensis) estuvieron presentes en Washington oriental a lo largo del Holoceno, pero los bisontes fueron abundantes solo durante un periodo mas frío y húmedo; los alces habían sido abundantes solo en el siglo veinte subsecuente a los transplantes y a la exterminación de los depredadores. La variación en la abundancia de alces a lo largo de Montana, Idaho y el oriente de Washington estuvo influenciada por la depredación humana, pero también por la historia biogeográfica, las diferencias en hábitat y el cambio climático.

Decision-making about artificial feeding in end-of-life care: literature review

JOURNAL OF ADVANCED NURSING, Issue 1 2008

Abstract Title.,Decision-making about artificial feeding in end-of-life care: literature review. Aim., This paper is a report of a review of nurses' roles and their perceptions of these roles in decision-making processes surrounding artificial food and fluid administration in adult patients. Background., Of all caregivers, nurses have the closest and most trusting relationship with severely ill patients and their families during the entire end-of-life care process. As a result, nurses become closely involved in complex ethical decision-making processes concerning artificial administration of food or fluids for these patients. Data sources., We searched seven electronic databases (1990,2007) and examined the reference lists of relevant papers. Review methods., This mixed methods review was conducted with guidance of the United Kingdom Centre for Reviews and Dissemination guidelines on systematic reviews. Results., Although their direct impact is limited, nurses play a significant indirect role during decision-making processes. Because of their unique position, they often initiate decision-making processes, function as patient advocates and provide guidance, information and support to patients and families. Although nurses considered their role to be very valuable, they felt that their role was not always defined clearly or appreciated. Whether nurses experience decision-making processes positively depended on several contextual factors. Conclusion., Given their knowledge and practice skills, nurses are in a prime position to contribute valuably to decision-making processes. Nevertheless, they remain sidelined. For nurses to receive sufficient recognition, their decision-making tasks and responsibilities need to be clarified and made manifest to other participants. [source]

Variations in bark-stripping by red deer Cervus elaphus across Europe

MAMMAL REVIEW, Issue 3 2006
HÉLÈNE VERHEYDEN
ABSTRACT 1The literature on bark-stripping by red deer Cervus elaphus in Europe is reviewed to reveal quantitative variation in this behaviour and relate it to deer density and local characteristics such as dominant tree species, occurrence of artificial feeding, altitude, region and size of the study site. We also review the importance of bark in red deer diets over the seasons and discuss the causes of bark-stripping, focusing on the significance of bark as food. 2Over the 36 sites examined, the rate of bark-stripping was highly variable (from 0 to 84% of susceptible trees debarked), with less damage in Scotland than in other European sites for which bark-stripping rates were higher at high red deer density. Altitude, the size of the study site, the number of dominant tree species and the occurrence of artificial feeding do not significantly relate to the rate of bark-stripping. 3Bark sometimes made up a large proportion of red deer diet (> 10%), especially in areas with severe winters (high levels of snow), whereas in study sites with mild winters, bark was practically not eaten at all. 4These results suggest that severe bark-stripping could be related to a reduction in food resource availability. This food availability hypothesis needs to be better documented, dealing particularly with the possible interaction between food availability and red deer density. [source]

Patient involvement in health-related decisions during prolonged critical illness,

RESEARCH IN NURSING & HEALTH, Issue 4 2007
Mary Beth Happ
Abstract We describe patterns of communication of patients involved in health-related decision making during prolonged mechanical ventilation (PMV). Data were collected using observation, interview, and record review. Twelve of 30 patients participated in decisions about initiating, withdrawing, and withholding life-sustaining treatment, surgery, artificial feeding, financial/legal issues, discharge care, and daily care procedures. Patient involvement was largely validation or confirmation of what clinicians and families had already decided. Patients' participation was enlisted by clinicians and family members even when the patients did not exhibit full decisional capacity. Patient involvement in health-related decisions during prolonged critical illness is a shared and negotiated process that requires continued empirical study and ethical analysis. © 2007 Wiley Periodicals, Inc.

Hospital system costs of artificial infant feeding: estimates for the Australian Capital Territory

AUSTRALIAN AND NEW ZEALAND JOURNAL OF PUBLIC HEALTH, Issue 6 2002
Julie P. Smith
Objective: To estimate the attributable ACT hospital system costs of treating selected infant and childhood illnesses having known associations with early weaning from human milk. Method: We identified relative risks of infant and childhood morbidity associated with exposure to artificial feeding in the early months of life vs breastfeeding from cohort studies cited by the American Academy of Pediatrics in 1997 as establishing the protective effect of breastfeeding. Data for ACT breastfeeding prevalence is assessed from a 1997 prospective population-based cohort study of 1,295 women. ACT Hospital Morbidity Data and DRG treatment costs were used to estimate the attributable fraction of costs of hospitalisation for gastrointestinal illness, respiratory illness and otitis media, eczema, and necrotising enterocolitis. Results: Although initiation rates were high (92%), less than one in 10 ACT infants are exclusively breastfed for the recommended six months, mainly due to supplementation or weaning on to formula within the first three months and the early introduction of solids by breastfeeding mothers. This study suggests the attributable hospitalisation costs of early weaning in the ACT are about $1 -2 million a year for the five illnesses. Conclusions and implications: Early weaning from breast milk is associated with significant hospital costs for treatment of gastrointestinal illness, respiratory illness and otitis media, eczema, and necrotising enterocolitis These costs are minimum estimates of the cost of early weaning as they exclude numerous other chronic or common illnesses and out-of-hospital health care costs. Higher rates of exclusive breastfeeding would reduce these costs. Interventions to protect and support breastfeeding are likely to be cost-effective for the public health system. [source]

Reducing the Risk for Formula-Fed Infants: Examining the Guidelines

BIRTH, Issue 1 2010
Elizabeth Hormann BA, HGDip, IBCLC
ABSTRACT:, Early in this century, outbreaks of Enterobacter sakazakii among infants fed on powdered infant formula in Western Europe and the United States forced a rethinking of the cherished belief that artificial feeding is a very safe choice for infants in the developed world. Alarmed by these reports, the World Health Organization and the Food and Agriculture Organization convened an Expert Meeting in 2004 to determine the causes and again in 2006 to develop guidelines for reducing the risk to infants from intrinsic bacterial contamination in powdered infant formula. Reducing the frequency of contamination at the manufacturing level would eliminate about 80 percent of the problem. Reconstituting the formula with water boiled and cooled to no less than 70° C is critical to destroy remaining bacteria. Arguments from the infant formula industry, some segments of the medical community, and some Western countries against this "lethal step" trivialize the scope and severity of the problem and ignore clear scientific evidence.
