Ureteral length in live donor kidney transplantation; Does size matter?

The aim of this study was to evaluate the role of ureteral length on urological complications. Data were retrospective collected from the INEX‐trial database, a RCT to compare the intravesical to the extravesical ureteroneocystostomy. Ureteral length was measured in 198 recipients and used to divide recipients into three categories based on interquartile ranges: short (≤8.5 cm), medium (8.6–10.9 cm) and long ureters (≥11 cm). Urological complications were defined as the number of percutaneous nephrostomy placements (PCN). Fifty recipients fell into the short, 98 into the medium and 50 recipients into the long ureter category. Median follow‐up was 26 (range 2–45) months. There was no significant difference in number of PCN placements between the categories. There were 9 (18%) PCN placements in the short ureter category, 21 (20%) in medium ureter category and 10 (21%) in the long ureter category, P = 0.886. Risk factor analysis for gender, arterial multiplicity and type of ureteroneocystostomy showed no differences in PCN placements between the three ureteral length categories. We conclude that ureteral length alone does not seem to influence the number of urological complications.     

The cholinomimetic agent carbachol induces headache in healthy subjects

The parasympathetic nervous system is likely to be involved in migraine pathogenesis. We hypothesized that the cholinomimetic agonist carbachol would induce headache and vasodilation of cephalic and radial arteries. Carbachol (3 µg/kg) or placebo was randomly infused into 12 healthy subjects in a double-blind crossover study. Headache was scored on a verbal rating scale from 0–10. Velocity in the middle cerebral artery (V_MCA) and diameter of the superficial temporal artery (STA) and radial artery (RA) were recorded. Nine participants developed headache after carbachol compared with three after placebo. The area under the curve for headache was increased after carbachol compared with placebo both during infusion (0–30 min) ( P  = 0.042) and in the postinfusion period (30–90 min) ( P  = 0.027). Carbachol infusion caused a drop in V_MCA ( P  = 0.003) and an increase in STA diameter ( P  = 0.006), but no increase in the RA diameter ( P  = 0.200). In conclusion, the study demonstrated that carbachol caused headache and dilation of cephalic arteries in healthy subjects.     

Pain assessment in patients with possible vascular dementia

PREVIOUS studies comparing Alzheimer's disease (AD) patients with the normal elderly suggest that AD patients experience less pain. In the present study, pain reporting in 20 patients with possible vascular dementia (VaD) was compared to 20 nondemented elderly who had comparable pain conditions. It was hypothesized that, due to de-afferentiation, the possible VaD patients would experience more pain than the cognitively intact elderly. Pain assessment was conducted using three visual analogue scales, (1) the Coloured Analogue Scale (CAS) for Pain Intensity, (2) the CAS for Pain Affect, and (3) the Faces Pain Scale (FPS); a verbal pain questionnaire, Number of Words Chosen--Affective (NWC-A) of the McGill Pain Questionnaire; and an observation scale, the Checklist of Nonverbal Pain Indicators (CNPI). Results showed a significant increase in the scores on the CAS for Pain Affect and the FPS in the demented patients compared to the control group. There was a tendency for an increase in scores on the CNPI in the VaD group. These results suggest that patients with possible VaD suffer more pain than healthy elderly without cognitive impairment.     

贴报-P2临床毒理学、药理学和疗效研究

5-Flourouracil（5-FU） is one of well known anti-cancer drugs, but its toxicity in normal lymphocytes remains a major problem in chemotherapy. The eastern traditional drug, Bupleuri radix（BR）, has been used for the treatment of liver diseases and contains series of triterpene saponins.     

The concept of quality of life in dementia in the different stages of the disease

In order to conceptually define quality of life (QOL) in dementia, the literature on QOL in the elderly population, in chronic disease and in dementia was studied. Dementia is a progressive, age-related, chronic condition and to avoid omissions within the dementia-specific concept of QOL, a broad orientation was the preferred approach in this literature study. Adaptation is a major outcome in studies investigating interventions aimed at improving QOL in chronic conditions, but to date, it has not been used in the definition of QOL. It is argued that adaptation is an important indication of QOL in people with chronic diseases and therefore also in dementia. Some crucial issues in assessing dementia-related QOL that are relevant to clarify the continuing debate on whether QOL, particularly in dementia, can be measured at all, are discussed. Then the following conceptual definition is offered: dementia-specific QOL is the multidimensional evaluation of the person-environment system of the individual, in terms of adaptation to the perceived consequences of the dementia.     

End-of-life decision making in nursing home residents with dementia and pneumonia: Dutch physicians' intentions regarding hastening death

When patients with severe dementia become acutely ill, little is known about the extent to which physicians take actions intended to hasten death. For 143 nursing home patients with dementia who died of pneumonia after a decision not to treat with antibiotics, we asked Dutch facility-employed physicians whether they intended to hasten death and any estimated life shortening. In 53% of cases, the physicians reported an explicit intention to hasten death; in another 41% of cases they reported taking into account a probability or certainty that the withholding of antibiotics or other palliative treatments would hasten death. Opiates were frequently used for symptom control (43%), but the administration of medications specifically intended to induce death was rare (2%). Considering all treatments, physicians estimated that life was shortened by 24 hours or less in 46% of patients and 1 month or longer in 24% of patients. The frequent withholding of antibiotics with an intention to hasten death may reflect a willingness to abandon a cure-oriented approach in dying patients for whom prolongation of life is not an aim. The results reflect the importance of explicit goals for medical interventions in patients with end-stage dementia where life-prolonging treatments may be seen as prolonging suffering.     

Dependency of magnetocardiographically determined fetal cardiac time intervals on gestational age,gender and postnatal biometrics in healthy pregnancies

Background  

Magnetocardiography enables the precise determination of fetal cardiac time intervals (CTI) as early as the second trimester of pregnancy. It has been shown that fetal CTI change in course of gestation. The aim of this work was to investigate the dependency of fetal CTI on gestational age, gender and postnatal biometric data in a substantial sample of subjects during normal pregnancy.     

The 1996 welfare law: key elements and reauthorization issues affecting children

The Personal Responsibility and Work Opportunity Reconciliation Act of 1996 changed the social policy landscape for children in many ways. It replaced the prior welfare program with block grants to the states entitled Temporary Assistance for Needy Families, and modified a broad array of other programs and initiatives affecting low-income children. This article describes the key themes dominating the debate over welfare reform in 1996, specifically: Increased state discretion in program design, leading to more variability in states' eligibility requirements and services provided to low-income families; More stringent work requirements even for parents of very young children; Time limits on the use of federal funds for cash assistance, and a strong focus on caseload reduction; Increased emphasis on parental responsibility, with stronger child support requirements; and Increased emphasis on reducing out-of-wedlock births, including bonuses to states with the largest reductions, and special requirements for unmarried teen parents who seek welfare. Although child well-being received little attention during the congressional debates in 1996, the authors conclude with the hope that improving child outcomes and child well-being will emerge as a key theme when the law is reauthorized in 2002.
