All-cause and cardiovascular mortality in diabetic subjects increases significantly with reduced estimated glomerular filtration rate (eGFR): 10 years' data from the South Tees Diabetes Mortality study.

AIMS: To investigate the association between estimated glomerular filtration rate (eGFR) and total and cardiovascular mortality in a population-based cohort of diabetic subjects. METHODS: A longitudinal study using a population-based district diabetes register comprising 3288 subjects in South Tees, UK. The eGFR was calculated using the Modification of Diet in Renal Disease (MDRD) study equation. Patients were stratified by baseline eGFR into five stages as per the National Kidney Foundation guidelines: Stage 1, eGFR > 90; Stage 2, eGFR 60-89; Stage 3, eGFR 30-59; Stage 4, eGFR 15-29; and Stage 5, eGFR < 15 ml/min per 1.73 m(2). Main outcome was all-cause and cardiovascular mortality between 1 January 1994 and 31 July 2004. RESULTS: At baseline, mean age (58.4 years) differed between groups. Persons with lower eGFR were older (P < 0.001). Thirty-six percent (n = 1193, males 56%) had died by 10 years (cardiovascular cause in 60%). Median follow-up was 10.5 years amounting to 28 342 person years. Stages 4 and 5 (eGFR 相似文献   

1142例胃癌切除术围手术期死亡因素分析

目的研究影响胃癌围手术期死亡的主要因素,为指导选择合理的切除范围和手术方式提供依据。方法回顾1989年1月至2004年3月胃癌手术后1142例患者的临床资料,按照不同年代分为3组,第1组:1989年1月至1994年1月,405例;第2组:1994年2月至1999年1月,377例;第3组:1999年2月至2004年3月,360例。比较3组间的围手术期死亡率,采用Logistic多因素回归分析研究影响手术死亡率的危险因素。结果全组患者术后并发症发生率和死亡率分别为11.2%(128/1142)和3.6%(41/1142)。第1、2、3组的术后并发症发生率依次为13.1%、10.1%和10.3%;3组比较,P>0.05。3组手术死亡率依次为4.7%、3.4%和2.5%,3组比较,P>0.05。术后最常见的并发症是吻合口瘘(24.2%,31/128),影响手术死亡的主要因素为临床Ⅳ期、姑息性切除术、联合脏器切除及术前合并症的存在(P<0.05)。Logistic多元回归分析显示淋巴结的清除范围和手术方式不是影响手术死亡的主要因素(P>0.05)。结论胃癌晚期患者手术死亡率高,对胃癌Ⅳ期患者行姑息性切除手术时应避免施行不必要的淋巴结清除及联合脏器切除术。     

围生期窒息发生率和死亡率近10年变迁及相关因素

目的 分析近10年来围生期窒息发生率和死亡率的变迁，探讨围生期窒息相关因素及开展新法复苏对围生期窒息发生率和死亡率的影响。方法对近10年郑州大学第三附属医院分娩的所有活产新生儿的病历资料进行回顾性分析，计算窒息的发生率、死亡率、病死率，观察上述指标的逐年变化趋势及季节变化的情况，并探讨性别、双／多胎、出生体质量、胎龄分娩方式对这些指标的影响。结果轻度窒息发生率在开展新法复苏后明显下降，并稳定在1．5％左右，而重度窒息的发生率和病死率均无明显变化。窒息儿的发生率以4月份最高，但死亡率和病死率以7月份最高。窒息的发生还与性别、双／多胎、出生体质量、早产以及阴道助产有关。结论围生期窒息的发生与性别、双／多胎、出生体质量、胎龄密切相关；新法复苏能显著降低轻度窒息的发生率，对重度窒息的发生率和窒息病死率无明显影响；窒息儿的死亡率和病死率与季节有关。     

Can the process indicators for emergency obstetric care assess the progress of maternal mortality reduction programs? An examination of UNFPA Projects 2000-2004.

BACKGROUND: In view of the disappointing progress made in the last 20 years in reducing maternal mortality in low-income countries and before going to scale in implementing the new evidence-based strategies, it is crucial to review and assess the progress made in pilot countries where maternal mortality reduction programs focused on emergency obstetric care. OBJECTIVE: To review the process indicators recommended for monitoring emergency obstetric care and their application in field situations, examining the conditions under which they can be used to assess the progress of maternal mortality reduction programs. METHODS: Five of the six UN recommended process indicators were monitored annually for 5 years in selected districts of Morocco, Mozambique, India and Nicaragua. Trends are presented and discussed. RESULTS: With specific variations due to different local situations in the four countries and in spite of variations in quality of data collection, all indicators showed a consistent positive trend, in response to the inputs of the programs. CONCLUSIONS: The UN process indicators for emergency obstetric care should continue to be promoted, but with two important conditions: (1) data collection is carefully checked for quality and coverage; (2) efforts are made to match process and outcome indicators (maternal and perinatal mortality, incidence of complications).     

Mortality in patients with diabetic neuropathic osteoarthropathy (Charcot foot).

OBJECTIVE: To determine the mortality of a population of patients diagnosed with Charcot neuropathic osteoarthropathy managed by a single specialist unit and to compare the results with a control population. METHODS: We have undertaken a retrospective analysis of all cases of Charcot foot on the comprehensive database which has been maintained at the specialist diabetic foot clinic at the City Hospital, Nottingham since 1982. Survival and the incidence of amputation (major and minor) was compared with a control population referred with uncomplicated neuropathic ulceration. Controls were individually matched for gender, age (+/-2 years), disease type, disease duration (+/-2 years) and year of referral (+/-3 years). RESULTS: Forty-seven cases (21 female, 26 male) of Charcot foot were identified, of whom 18 (38.3%) had Type 1 diabetes. Mean age and disease duration at presentation were 59.2 +/- 13.4 (sd) and 16.2 +/- 11.2 years, compared with 59.7 +/- 12.6 and 16.3 +/- 11.2 years, respectively, in the controls. Twenty-one (44.7%) of those with Charcot had died, after a mean interval of 3.7 +/- 2.8 years. This compared with 16 (34.0%) after a mean 3.1 +/- 2.7 years in the control group. Mean duration of follow-up in the survivors was 4.7 +/- 4.9 years (Charcot) and 5.3 +/- 3.9 years (controls). A total of 11 (23.4%) Charcot patients had had a major amputation on the side of the index lesion, compared with five (10.6%) controls. There was no difference between the two groups (P > 0.05, Chi-square). CONCLUSIONS: The mortality in this group of patients with Charcot foot was higher than expected. Nevertheless, there was no difference between those with Charcot and those with uncomplicated neuropathic ulceration. It is possible that it is neuropathy, rather than Charcot osteoarthropathy, which is independently associated with increased mortality in diabetes. The mechanism underlying any such association is not known. There is a need for a formal, prospective, multicentre study to investigate the life expectancy and cardiovascular risk of those with Charcot osteoarthropathy.

Factors predicting mortality in midlife adults with and without Down syndrome living with family

Background Little is known about the mortality of individuals with Down syndrome who have lived at home with their families throughout their lives. The current study evaluates the predictors, causes and patterns of mortality among co‐residing individuals in midlife with Down syndrome as compared with co‐residing individuals with ID owing to other causes. Method This paper examines mortality in 169 individuals with and 292 individuals without Down syndrome from 1988 to 2007. Dates and causes of death were obtained from maternal report, the Social Security Death Index and the National Death Index. Risk factors predicting mortality, including demographic variables, transition variables, and initial and change measures of health, functional abilities and behaviour problems, were obtained from maternal report. Results Having Down syndrome is a risk factor of mortality, net of other risk factors including older age, poorer functional abilities, worsening behaviour problems, residential relocation and parental death. The causes of death among individuals with and without Down syndrome who are in midlife and co‐residing with their families are similar, and are most commonly due to cardiovascular or respiratory problems. Conclusions The findings indicate that midlife adults with Down syndrome who co‐reside with their families generally exhibit similar causes of mortality as do midlife adults with intellectual disability owing to other causes, but show an elevated risk of mortality in midlife net of other variables, such as age and changes in functional abilities and behaviour problems.

Soluble CD30 in pediatric patients with atopic dermatitis

Atopic dermatitis (AD) is a chronic, inflammatory skin disease in which a pathogenetic role of Th2 cells has been supposed. This study investigated the presence of soluble CD30 (sCD30), an activation marker of T-cell clones able to produce Th2-type cytokines, in sera from pediatric patients affected by AD ( n =25) with no symptoms of asthma or rhinitis. The severity of the disease was graded by both the SCORAD and Costa et al. clinical scoring systems. Serum levels of sCD30 were significantly higher in patients with AD in respect to both normal donors ( n =20) and urticaria patients ( n = 10), and a positive correlation between serum sCD30 and clinical score was found ( r =0.508; P =0.01) when AD patients were evaluated by Costa et al.'s method. Furthermore, a significant association ( r -=0.443; P =0.027) between sCD30 and serum levels of the soluble interleukin (IL)-2 receptor (sIL-2R) was observed in AD. The presence of high amounts of sCD30 in atopic patients seems to confirm the role of this molecule as an activation marker useful for in vivo evaluation of a Th2 immune response, and the correlation observed with both clinical score and sIL-2R levels indicates the role of sCD30 as an additional marker of disease activity in pediatric patients with AD.
