Being there: the essence of end-of-life nursing care

Competent and compassionate end-of-life care is the right of everyone. Nursing and the health care profession are obligated to meet this need for their patients and provide crucial information and support. Continued efforts must be made to increase our knowledge about the normal dying process, symptom management, and the role of the interdisciplinary team in supporting patients in their final wishes for a "good death".     

Case report: purple urine bag syndrome

Purple urine bag syndrome (PUBS) was first reported in 1978. PUBS is rare, occurs predominantly in constipated women, chronically catheterized and associated with some bacterial urinary infections that produce sulphatase/phosphatase. The etiology is due to indigo (blue) and indirubin (red) or to their mixture that becomes purple. A chain reaction begins in the gastrointestinal tract with tryptophan as described in the article.     

Psychosocial healing and post-conflict social reconstruction in the former Yugoslavia

Post-conflict reconstruction encompasses social, physical and political reconstruction. Social reconstruction entails rebuilding the human interactions that allow a society to function. This involves the healing of psychological and social wounds of individuals and society. Psychosocial healing is a process to promote psychological and social health of individuals, families and community groups. The Medical Network for Social Reconstruction in the Former Yugoslavia has pioneered a broad range of psychosocial healing programmes including community-integration programmes, development of volunteer action, and training of professional and lay people to take part in psychosocial healing. These programmes have demonstrated that psychosocial healing can be an effective way to heal post-conflict societal trauma and contribute to rebuilding society with an improved quality of life.     

A delay in bone marrow transplantation after partial conditioning improves engraftment

BACKGROUND: In the present study we examined the effect of the timing of marrow infusion on engraftment in nonmyeloablatively conditioned mice. METHODS: B10 mice were conditioned with decreasing doses of total body irradiation (TBI) and reconstituted with bone marrow cells (BMCs) from major histocompatibility complex-disparate donor B10.BR mice at 0 or 6 hr, or on days 1, 2, 3, 4, 5, 8, and 12 with respect to TBI. RESULTS: After undergoing conditioning with 700 cGy TBI and transplantation with 15 x 10(6) BMCs, 100% of recipients engrafted if the marrow was infused between 0 and 4 days after TBI. For lower doses of TBI, a delay in infusion of the marrow after TBI conditioning was associated with a significant increase in engraftment. Significantly less engraftment was achieved in animals conditioned with 600 cGy TBI if the marrow was infused at 0 or 6 hr compared with a 1- to 4-day delay. When the TBI was decreased to 500 cGy, engraftment occurred only when the transplant was performed between days 2 and 8. The highest proportion of recipients engrafted when the marrow was infused on day 4. This enhanced engraftment after a delay in marrow infusion is associated with a significant reduction in host mixed lymphocyte reaction reactivity and is correlated inversely with serum levels of interleukin-6 in the recipient. CONCLUSIONS: These data demonstrate for the first time that a delay between conditioning and marrow infusion significantly improves allogeneic engraftment in nonmyeloablatively conditioned recipients and reduces the total conditioning required.     

Growth hormone selectively improves intestinal cholesterol absorption after jejunoileal autotransplantation in pigs

Background/Purpose

Small bowel transplantation impairs enteric function and causes malabsorption of cholesterol and bile acids. Growth hormone stimulates intestinal absorptive function. The authors hypothesized that long-term growth hormone therapy could improve absorption of bile acids and cholesterol after autotransplantation of the jejunoileum.

Methods

Sixteen pigs with similar food, cholesterol, and fat intake underwent either sham laparotomy or a model of jejunoileal autotransplantation, including extrinsic autonomic denervation, lymphatic interruption, and in situ cold ischemia. Five randomly chosen autotransplanted animals received daily growth hormone treatment for 8 weeks. Serum lipids, absorption, and excretion of cholesterol, bile acids, and fat were determined after 8 weeks. Mucosal morphometrics, proliferation, and enzyme activities were determined. Plasma cholesterol precursors and plant sterols, respective markers of cholesterol synthesis and absorption, were measured after 2 and 8 weeks.

Results

After jejunoileal autotransplantation, growth hormone treatment significantly increased body weight gain, cholesterol absorption efficiency from 45.1% to 62.1%, plasma campesterol to cholesterol proportions, and biliary secretion of cholesterol. With or without growth hormone treatment, autotransplantation significantly increased fecal bile acid excretion, plasma cholesterol precursors, fecal bacterially modified neutral sterols, mucosal thickness of the ileum (but not jejunum), and intestinal transit time when compared with sham-operated animals. Crypt cell proliferation, mucosal enzyme activities, and microvilli showed no differences between the groups.

Conclusions

These findings suggest that growth hormone treatment selectively improves cholesterol, but not bile acid absorption, after autotransplantation of the jejunoileum.     

An evaluation of continuous positive airway pressure (CPAP) therapy in the treatment of hypernasality following traumatic brain injury: a report of 3 cases

OBJECTIVE: To evaluate the effectiveness of continuous positive airway pressure (CPAP) therapy in the treatment of hypernasality following traumatic brain injury (TBI). DESIGN: An A-B-A experimental research design. Assessments were conducted prior to commencement of the program, midway, immediately posttreatment, and 1 month after completion of the CPAP therapy program. PARTICIPANTS: Three adults with dysarthria and moderate to severe hypernasality subsequent to TBI. OUTCOME MEASURES: Perceptual evaluation using the Frenchay Dysarthria Assessment, the Assessment of Intelligibility of Dysarthric Speech, and a speech sample analysis, and instrumental evaluation using the Nasometer. RESULTS: Between assessment periods, varying degrees of improvement in hypernasality and sentence intelligibility were noted. At the 1-month post-CPAP assessment, all 3 participants demonstrated reduced nasalance values, and 2 exhibited increased sentence intelligibility. CONCLUSIONS: CPAP may be a valuable treatment of impaired velopharyngeal function in the TBI population.     

A Mediational Model of PTSD in World War II Veterans Exposed to Mustard Gas

Structural equation modeling (SEM) was used to examine associations among trauma-related contextual factors, initial psychological reactions, social support, and subsequent disclosure on posttraumatic stress disorder (PTSD) symptoms in a sample of World War II (WWII) veterans exposed to mustard gas (N = 305). A structural model suggested that initial psychological reaction mediated the relationship between variables related to the context of mustard gas exposure and severity of PTSD symptoms 50 years later. Unexpectedly, social support appeared to be positively related to PTSD symptoms, and not related to the contextual variables or initial psychological reactions. These findings contribute to our understanding of PTSD in older veterans, and have relevance for early intervention services to prevent PTSD among those at risk for exposure to toxic agents.
