How respect and kindness are experienced at the end of life by nursing home residents

Respect and kindness are core principles of nursing practice, yet little is known about how they are experienced by nursing home (NH) residents at the end of life. The aim of this study was to examine the factors associated with being treated with respect and kindness in the last month of life as an NH resident. A retrospective survey of 208 bereaved family members was conducted in 21 NHs located in a city in central Canada. The majority of participants indicated that the resident had always been treated with respect or kindness. However, significant differences emerged, with not all family members believing that their loved one had always been treated with respect or kindness. The apparent lapses in care practices are troubling and indicate that steps must be taken to address them.     

Nociceptive sensations evoked from 'spots' in the skin by mild cooling and heating

It was recently found that nociceptive sensations (stinging, pricking, or burning) can be evoked by cooling or heating the skin to innocuous temperatures (e.g., 29 and 37 degrees C). Here, we show that this low-threshold thermal nociception (LTN) can be traced to sensitive 'spots' in the skin equivalent to classically defined warm spots and cold spots. Because earlier work had shown that LTN is inhibited by simply touching a thermode to the skin, a spatial search procedure was devised that minimized tactile stimulation by sliding small thermodes (16 and 1mm(2)) set to 28 or 36 degrees C slowly across the lubricated skin of the forearm. The procedure uncovered three types of temperature-sensitive sites (thermal, bimodal, and nociceptive) that contained one or more thermal, nociceptive, or (rarely) bimodal spots. Repeated testing indicated that bimodal and nociceptive sites were less stable over time than thermal sites, and that mechanical contact differentially inhibited nociceptive sensations. Intensity ratings collected over a range of temperatures showed that LTN increased monotonically on heat-sensitive sites but not on cold-sensitive sites. These results provide psychophysical evidence that stimulation from primary afferent fibers with thresholds in the range of warm fibers and cold fibers is relayed to the pain pathway. However, the labile nature of LTN implies that these low-threshold nociceptive inputs are subject to inhibitory controls. The implications of these findings for the roles of putative temperature receptors and nociceptors in innocuous thermoreception and thermal pain are discussed.     

Potent and selective inhibition of human cytomegalovirus replication by 1263W94, a benzimidazole L-riboside with a unique mode of action

Benzimidazole nucleosides have been shown to be potent inhibitors of human cytomegalovirus (HCMV) replication in vitro. As part of the exploration of structure-activity relationships within this series, we synthesized the 2-isopropylamino derivative (3322W93) of 1H-beta-D-ribofuranoside-2-bromo-5,6-dichlorobenzimidazole (BDCRB) and the biologically unnatural L-sugars corresponding to both compounds. One of the L derivatives, 1H-beta-L-ribofuranoside-2-isopropylamino-5,6-dichlorobenzimidazole (1263W94), showed significant antiviral potency in vitro against both laboratory HCMV strains and clinical HCMV isolates, including those resistant to ganciclovir (GCV), foscarnet, and BDCRB. 1263W94 inhibited viral replication in a dose-dependent manner, with a mean 50% inhibitory concentration (IC(50)) of 0.12 +/- 0.01 microM compared to a mean IC(50) for GCV of 0.53 +/- 0.04 microM, as measured by a multicycle DNA hybridization assay. In a single replication cycle, 1263W94 treatment reduced viral DNA synthesis, as well as overall virus yield. HCMV mutants resistant to 1263W94 were isolated, establishing that the target of 1263W94 was a viral gene product. The resistance mutation was mapped to the UL97 open reading frame. The pUL97 protein kinase was strongly inhibited by 1263W94, with 50% inhibition occurring at 3 nM. Although HCMV DNA synthesis was inhibited by 1263W94, the inhibition was not mediated by the inhibition of viral DNA polymerase. The parent benzimidazole D-riboside BDCRB inhibits viral DNA maturation and processing, whereas 1263W94 does not. The mechanism of the antiviral effect of L-riboside 1263W94 is thus distinct from those of GCV and of BDCRB. In summary, 1263W94 inhibits viral replication by a novel mechanism that is not yet completely understood.     

Pediatric brain tumor patients: their parents' perceptions of the hospital experience.

Studies have shown that admission to the hospital of a child can induce feelings of fear and helplessness in parents, challenging usual patterns of coping and parenting competence. Stress has been associated with parents' need to establish effective communication with staff and their need for information, ready access to their children, and participation in decision making relating to their child's care. This study of coping and adjustment was undertaken with the parents, including mothers and fathers, of children under 18 years of age diagnosed with a brain tumor, presenting at Royal Children's Hospital, Melbourne, between 2001 and 2002 (N=53). It was a prospective study using repeated measures over time. Participants in the study were involved in a questionnaire interview at 4 different points: at the time of diagnosis, 6 months postdiagnosis, 1 year postdiagnosis, and 2 years postdiagnosis, in which they were asked, among other things, about their experience of the hospital. The point of diagnosis was marked by a high level of dependence, with parents coping with rapid decision making and shock, and the surrender of care of their child. Parents identified high levels of information need but noted that they were often too stressed to take in information early on, and that this information need persisted up to the 2-year postdiagnosis point. More parents expressed dissatisfaction with the hospital and particularly with their interactions with the health care team at the 6-month post-diagnosis period, reflecting a possible reduction in attention given to families once they had settled into the treatment routine and the crisis of diagnosis had passed.     

Psychosocial interventions for patients with head and neck cancer: past, present, and future

A diagnosis of head and neck cancer, like any cancer diagnosis, is often accompanied by much fear and uncertainty. In addition, patients with head and neck cancer face difficulties in eating, chewing, drinking, breathing, speaking, as well as changes in appearance. Simultaneously, the burden of head and neck cancer is often manifested in psychosocial dysfunction, which can have a negative impact on quality of life. Although a phenomenon well recognized, little is known about many factors that influence or impact psychosocial dysfunction in individuals with head and neck cancer. Even less is known about the effective management of psychosocial dysfunction. To date, there is evidence to suggest that psychosocial interventions generally provide an overall positive effect. Moreover, some intervention studies, such as education alone, have failed to achieve the desired results. In addition, some studies suggest an advantage of cognitive- behavioral therapy over other forms of psychological treatment. With the growing impetus to investigate factors associated with psychosocial dysfunction, and considerable advancement in the development and validation of many global and disease-specific measures, there is an opportunity for further research to develop an appropriate clinical intervention program for such patients.     

Implementing an incontinence management protocol in long-term care. Clinical outcomes and costs

This article describes clinical outcomes and costs of implementing an incontinence management protocol based on the recommendations contained in the Agency for Health Care Quality and Research clinical practice guidelines on incontinence and pressure ulcer prevention. Following implementation of the protocol, 63 nursing home residents were followed for 6 months and assessed for the presence of wetness or pressure ulcers. Facility costs for incontinence management were accumulated. Fifty-four percent of the residents (34 of 63) received treatments for incontinence and 60% (20 of 34) became dry. Pressure ulcer rates decreased from 16 participants developing 26 pressure ulcers to 3 participants developing 5 ulcers. Facility cost of incontinence management for 6 months was $86,436 with 46% attributed to direct labor costs. Toileting was the most expensive component, costing $36,755. Total daily cost of incontinence management was $573 ($9.09 +/- 10.52 per resident). Implementation of the incontinence protocol resulted in improved "dryness" of the participants and reduced pressure ulcer incidence.     

Stimulation of granulation tissue formation by platelet-derived growth factor in normal and diabetic rats.

Subcutaneous implantation of Hunt-Schilling wound chambers in rats induces a wound repair response causing the chamber first to fill with fluid and subsequently with connective tissue. The presence of a type I collagen gel encouraged a more rapid dispersion of cells throughout the chamber but had no effect on the rate of new collagen deposition. Addition of platelet-derived growth factor (PDGF; 50 ng/chamber) to the collagen-filled chambers caused an earlier influx of connective tissue cells, a marked increase in DNA synthesis, and a greater collagen deposition in the chamber during the first 2 wk after implantation. After 3 wk, however, the levels of collagen were similar in PDGF-supplemented and control chambers. Diabetic animals exhibited a decreased rate of repair which was restored to normal by addition of PDGF to the wound chamber. Combinations of PDGF and insulin caused an even more rapid increase in collagen deposition. These results suggest that the levels of various growth factors, particularly PDGF, may be limiting at wound sites and that supplementation of wounds with these factors can accelerate the rate of new tissue formation.     

Specificity in the Relations among Childhood Adversity, Early Maladaptive Schemas, and Symptom Profiles in Adolescent Depression

The present cross-sectional study examined the relations of particular forms of childhood adversity (e.g., emotional maltreatment vs. physical abuse vs. sexual abuse) to specific early maladaptive schema themes (e.g., worthlessness/loss vs. danger) and symptom profiles (i.e., anhedonic vs. anxious). Seventy-six depressed adolescents retrospectively reported on their childhood experiences of emotional maltreatment, physical abuse, and sexual abuse in a contextual semi-structured interview. They were also administered the Young Schema Questionnaire to measure early maladaptive schemas, and the Mood and Anxiety Symptom Questionnaire to measure anhedonic and anxious symptomatology. Consistent with specificity hypotheses, schemas with themes of loss/worthlessness preferentially mediated the relation between childhood adversity and anhedonic symptoms, while schemas with themes of danger preferentially mediated the relation between childhood adversity and anxious symptoms. Sexual abuse was not significantly associated with either depression or anxiety symptoms and, thus, mediation models involving sexual abuse were not tested. Implications for fine-grained models of etiology in depression are discussed.

Is radiation therapy required for patients with intermediate-risk rectal cancer?

Randomized trials have demonstrated that radiation therapy improves local control in patients with rectal cancer. Because pelvic irradiation may result in acute and/or late morbidity, identification of patients with the highest probability of benefiting from this therapy would be optimal. Though radiation is usually recommended for patients with tumors invading through the muscularis propria into the mesorectum with or without lymph-node involvement, several studies suggest that patients with only one of these risk factors may comprise a more favorable risk group who may not require radiation as part of their overall management. Current data permit identification of these patients, but no randomized studies have yet demonstrated that selected patients with locally advanced rectal cancer can safely be spared adjuvant or neoadjuvant radiation.     

Saturday-morning television: do sponsors promote high-risk behavior for burn injury?

Television has become an important tool for learning and socialization in children. Although television violence has been associated with adverse effects, data on depiction of fire and burn injury are lacking. We sought to determine whether Saturday-morning television programming, viewed primarily by children, depicts fire and burn injury as safe or without consequence, thus potentially increasing the incidence of burn injury in children. This was a prospective observational study. Saturday-morning children's television programs were videotaped from 7 AM to 11 AM for eight different television networks during a 6-month period. Tapes were scored for scenes depicting fire or smoke by independent observers. Recorded items included show category, scene type, gender target, context of fire, and outcome after exposure to flame. Fire events were documented during programs and their associated commercials. A total of 108 hours of children's programs, 16 hours per network, were recorded. Scenes depicting fire or smoke were identified 1960 times, with 39% of events occurring during the program itself and 61% in commercials. Fire was depicted as either safe or without consequence in 64% of incidents. Action adventure stories accounted for 56% of flame depictions. Overall, one incident involving flame and fire was portrayed for each 3 minutes of television programming. Saturday-morning television programming frequently depicts fire as safe, empowering, or exciting. The incidence of flame use in programming varies between stations but is most prevalent in action/adventure stories. Television commercials, although brief, provide the majority of the misinformation regarding fire. Medical professional societies should alert the public to this potential hazard and recommend responsible portrayal of fire in children's television programming.
