Quality of life in patients before and after kidney transplantation

Abstract

The aim of the present study was to differentially determine quality of life (QOL) in patients with end-stage renal disease (ESRD) after successful kidney transplantation (RT, Group A) compared with ESRD patients on a waiting list for RT (Group B). and with healthy controls (Group C) because opinions vary as to which treatment modality can best assure ESRD patients a high QOL.

Groups A, B and C each consisted of 149 persons, matched for age and gender. The Munich Quality of Life Dimensions List (MLDL) was used to measure global aspects of QOL. Distinct aspects of QOL were investigated by the Brief Symptom Inventory (BSI) and the Questionnaire for Social Support (K-22).

Groups A and C reported similar QOL. Which was significantly higher than in group B (p < .0001). This was particularly true for the physical and psychological status and daily activities, but not for the social situation. Groups A and B reported similar social support, which was significantly, lower than in group C (p < 006). Both ESRD groups reported higher satisfaction with social support than healthy controls (p < .0001).

Successful RT nor only improved distinct aspects of QOL in patients with ESRD, but even put them on par with healthy controls regarding physical and psychological QOL.

Lower social support and higher satisfaction with social support in both groups of ESRD patients should be evaluated further. From a clinical viewpoint. the improvement of physical and psychological aspects of QOL in RT patients is impressive; but more attention should be paid to constantly low social support in this group of patients. International multi center longitudinal studies to investigate QOL in ESRD patients under different treatments am necessary.     

Inhibitory Control in Children with Frontal Infarcts Related to Sickle Cell Disease

Evidence from past studies indicates that children with traumatic brain injury experience difficulties with inhibitory control. Less is known about inhibitory control in children with frontal brain injury related to cerebral infarction. We compared the inhibitory performance of children with frontal infarcts related to sickle cell disease with that of a control group of children with sickle cell disease but no history of cerebral infarction. On a stimulus-response reversal task, children with frontal infarcts made significantly more accuracy errors in the inhibitory condition than controls. Findings from this study and from previous research suggest that impairments in inhibitory control are common following frontal injury in a range of pediatric populations.     

Association between biological markers of sickle cell disease and cognitive functioning amongst Cameroonian children

Background: Some of the major complications of sickle cell disease (SCD) occur in the brain and apart from overt stroke, patients also present with cognitive impairments. We sought to evaluate the prevalence of cognitive deficits as well as their biological predicting factors in young SCD patients in Cameroon.

Methods: The cognitive performances of Cameroonian SCD young patients were evaluated using a neuropsychological test battery assessing four domains of cognitive functioning (executive functions, attention, memory, and sensory-motor skills) previously adapted and normalized on healthy subjects in Yaoundé.

Findings: Up to 37.5% of the 96 SCD patients aged 6 to 24 years (M?=?13.5, SD?=?4.9) had mild-to-severe cognitive deficits. The cognitive deficits tend to increase with age. There was a significant effect of SCD on executive functions and attention, whereas SCD patients performed as well as controls on memory and sensory-motor skills tests. Structural equation models showed a significant association between (a) severe anemia and lower executive functioning, (b) low fetal hemoglobin levels and lower executive functioning and attention, (c) history of cerebrovascular accidents and lower performances in executive functioning, sensory-motor skills, and memory, (d) pathological electroencephalogram and lower attention, and (e) abnormal Transcranial Doppler and lower memory.

Conclusion: SCD patients in Cameroon presented a very high prevalence of cognitive deficits, with a specific impairment of executive functions and attention. Routine neuropsychological evaluation for early detection of cognitive deficits in SCD patients could represent a cost-effective tool to implement in resource-limited contexts such as in sub-Saharan Africa.     

Connection between deformation-induced dislocation substructures and martensite formation in stainless steel

We report a quantitative connection between the strain amplitude dependencies of the organisation of dislocation cell substructures with the formation of deformation-induced martensite during cyclic plasticity of austenitic stainless steel at ambient temperature.     

THE ABSTRACT SUBLIME: Life as information waiting to be rewritten

We report here on a series of interaction-intensive, interdisciplinary workshops to foster collaboration among those who teach, study, and engage with the public about scientific developments and social change—the New England Workshop on Science and Social Change. We include one line of thinking that fed into the workshops and present an analysis of how they contribute to participants developing their interest and skills in collaboration. Workshop evaluations suggest that people are moved to develop themselves as collaborators when they view an experience or training as transformative. Four R's—respect, risk, revelation, and re-engagement—point to the important conditions for interactions among researchers to be experienced as transformative. Three considerations lie behind the focus on the process side of the workshops, not the specific workshop topics: (1) how best to fill in for readers what they missed out on by not being there; (2) workshops and meetings are a ubiquitous part of the culture of science and technology studies (STS) so it is valuable to examine this aspect of our own culture with a view to promoting positive changes; and (3) in some scientific fields organized multi-person collaborative processes form a highly valorized aspect of the culture of science, so reflection on experiences of participation and collaboration in STS might inform our analyses of fields that emphasize collaboration and group processes. Indeed, the authors' own involvement in the workshops extends our own STS work on actor networks and ‘heterogeneous engineering’, that is, the mobilization of a variety of resources by diverse agents spanning different realms of social action.     

Salutary effect of daily coping self-efficacy: impact on day-by-day coping to mood effects within dyads following hematopoietic stem cell transplantation

ABSTRACT

Background and Objectives: Little is known how coping self-efficacy (CSE) interacts with coping in dyad everyday life. The present study examined the moderating role of daily CSE in the relationship between coping and the next-day positive (PA) or negative (NA) affect in patient-caregiver dyads, following hematopoietic stem cell transplantation.

Design: This intensive longitudinal study was conducted during the first 28 days after post-transplant discharge.

Methods: Patients and their caregivers (N?=?200) maintained daily diaries on CSE, coping strategies, and affect.

Results: Daily CSE moderated daily coping–affect relationship: Positive emotion-focused coping increased PA in patients with higher than usual emotion-related CSE, whereas a buffering effect was found at lower than usual emotion-related CSE. A positive association between negative emotion-focused coping and NA in both patients and caregivers was stronger among those with lower than usual levels of emotion-related CSE. Higher than usual instrumental coping reduced NA in patients whose caregivers had higher than usual problem-related CSE, but increased NA for those whose caregivers had lower than usual instrumental CSE.

Conclusion: The findings show that daily CSE contributes to the effectiveness of daily coping within dyad, confirming its significance in effective adaptation and the role in the dyadic coping process.     

An “Opting In” Paradigm for Kidney Transplantation

Almost 60,000 people in the United States with end stage renal disease are waiting for a kidney transplant. Because of the scarcity of organs from deceased donors live kidney donors have become a critical source of organs; in 2001, for the first time in recent decades, the number of live kidney donors exceeded the number of deceased donors. The paradigm used to justify putting live kidney donors at risk includes the low risk to the donor, the favorable risk-benefit ratio, the psychological benefits to the donor, altruism, and autonomy coupled with informed consent; because each of these arguments is flawed we need to lessen our dependence on live kidney donors and increase the number of organs retrieved from deceased donors.

An “opting in” paradigm would reward people who agree to donate their kidneys after they die with allocation preference should they need a kidney while they are alive. An “opting in” program should increase the number of kidneys available for transplantation and eliminate the morally troubling problem of “organ takers” who would accept a kidney if they needed one but have made no provision to be an organ donor themselves. People who “opt in” would preferentially get an organ should they need one at the minimal cost of donating their kidneys when they have no use for them; it is a form of organ insurance a rational person should find extremely attractive.

An “opting in” paradigm would simulate the reciprocal altruism observed in nature that sociobiologists believe enhances group survival. Although the allocation of organs based on factors other than need might be morally troubling, an “opting in” paradigm compares favorably with other methods of obtaining more organs and accepting the status quo of extreme organ scarcity. Although an “opting in” policy would be based on enlightened self-interest, by demonstrating the utilitarian value of mutual assistance, it would promote the attitude that self-interest sometimes requires the perception that we are all part of a common humanity.     

Older age South African persons’ experiences of their needs with cell phone use

This study explored the needs met by cell phone use by older persons. Informants were 52 older South Africans (age range 65 to 89 years, male = 8, female = 44). The older persons completed a visual representation and semi-structured interviews on the needs met by their cell phone usage. Thematic analysis of the data revealed the following needs to be met by their cell phone usage: personal safety, sense of control, managing daily routine, and staying connected with loved ones. Findings are consistent with the propositions of the basic psychological needs theory (BPNT) regarding competence, autonomy, and personal well-being.
