新疆维吾尔自治区维吾尔族和哈萨克族及汉族女性胆囊结石的流行病学调查

背景　新疆维吾尔自治区胆囊结石患病率较高,我国女性胆囊结石患病率高于男性,但目前缺乏关于新疆维吾尔自治区女性胆囊结石患病率的研究。目的　了解新疆维吾尔自治区维吾尔族、哈萨克族、汉族女性胆囊结石患病率及其影响因素,为其胆囊结石预防及治疗提供依据。方法　2011年6—9月采用典型抽样再多阶段分层随机抽样的方法选取新疆维吾尔自治区女性居民为调查对象,采用统一自制且翻译成维吾尔文的调查问卷对其进行基本情况调查,同时对调查对象行肝脏和胆囊腹部超声检查。比较不同民族以及各民族不同初潮年龄、月经不调、生育数量、分娩年龄女性胆囊结石患病率,并采用多因素Logistic回归分析女性胆囊结石患病率的影响因素。结果　共发放问卷3 508份,有效问卷3 175份,有效回收率为90.5%。3 175例女性胆囊结石患病率为16.9%（535/3 175）,其中维吾尔族、哈萨克族、汉族女性胆囊结石患病率分别为24.0%（222/924）、10.8%（94/873）、15.9%（219/1 378）。3个民族间胆囊结石患病率比较,差异有统计学意义（χ2=57.913,P<0.001）。多因素Logistic回归分析结果显示,初潮年龄〔OR=1.167,95%CI（1.007,1.353）〕、月经不调〔OR=6.486,95%CI（4.636,9.532）〕、生育数量〔OR=1.355,95%CI（1.237,1.483）〕是维吾尔族女性胆囊结石的影响因素（P<0.05）;初潮年龄〔OR=1.296,95%CI（1.007,1.668）〕、生育数量〔OR=1.240,95%CI（1.022,1.504）〕是哈萨克族女性胆囊结石的影响因素（P<0.05）;生育数量〔OR=1.341,95%CI（1.214,1.482）〕、分娩年龄〔OR=0.942,95%CI（0.892,0.996）〕是汉族女性胆囊结石的影响因素（P<0.05）。结论　新疆维吾尔自治区女性胆囊结石患病率较高,其中维吾尔族女性胆囊结石患病率与初潮年龄、月经不调、生育数量有关;哈萨克族女性胆囊结石患病率主要与初潮年龄、生育数量有关;汉族女性胆囊结石患病率主要与生育数量、分娩年龄有关。因此临床工作中应重点关注初潮年龄延迟,生育数量多,分娩年龄小的女性,尤其是胆囊结石患病率较高的维吾尔族人群。

Increasing hip fracture incidence in California Hispanics, 1983 to 2000

Background: Hip fracture incidence in non-Hispanic whites (NHW) has decreased nationwide for the past 20 years. Little is known regarding hip fracture incidence among Hispanics, the largest, fastest growing minority in the United States. Objective: To assess the change in standardized hip fracture incidence from 1983 through 2000 in California Hispanics relative to other racial groups. Design: Hospitalizations for individuals older than 55 years with hip fracture requiring repair in acute care hospitals. Annual population estimates based on US Census Bureau estimates. Incidence standardized to national gender-age strata. Change in annual incidence calculated by weighted linear regression with robust variance estimates. Results: 372,078 hip fractures were identified. Age-adjusted annual incidence of hip fractures declined by 0.74% per year among women (655 to 568 per 100,000), but was unchanged among men (247 to 238 per 100,000). Among NHW women, the standardized annual incidence fell by 0.6% (4.0 fractures per 100,000) per year. Annual incidence among Hispanic women increased 4.9% (11.1 fractures per 100,000) per year. Annual incidence among Hispanic men increased by 4.2% (4.5 fractures per 100,000) per year and among NHW men by 0.5% (1.2 fractures per 100,000) per year. No significant change occurred among black or Asian women or men. Conclusions: Among California women, hip fracture incidence has doubled among Hispanics since 1983, while remaining unchanged or declining in other groups. Greater attention should be given to identification of individuals at risk for hip fracture and initiation of preventive measures in Hispanic populations.

Childhood adversity and psychiatric disorder in young adulthood: An analysis of 107,704 Swedes

Childhood adversity (CA) is associated with increased risks of psychiatric disorder in young adulthood, but details in this association are less known. We aimed to explore the association of a range of CA indicators with psychiatric disorder in young adulthood, and the impact of age at exposure, disorder type and accumulation of indicators. We capitalized on Sweden's extensive and high-quality registers and analyzed a cohort of all Swedes (N = 107,704) born in Stockholm County 1987–1991. Adversities included familial death, parental substance misuse and psychiatric disorder, parental criminality, parental separation, public assistance recipiency and residential instability. Age at exposure was categorized as: 0–6.9 years (infancy and early childhood), 7–11.9 years (middle childhood), and 12–14 years (early adolescence). Psychiatric disorders after age 15 were defined from ICD codes through registers. Risks were calculated as Hazard Ratios (HR) with 95% confidence intervals (CI).Results showed that exposure to at least one CA was associated with an increased risk of psychiatric disorder (HR 1.4, 95% CI: 1.3–1.4). Risks were increased for mood, anxiety, and psychotic disorders and ADHD but not for eating disorders. The risk varied with type of disorder but was similar for all exposure periods. Individuals with multiple (3+) CAs had a two-fold risk of psychiatric disorder (HR 2.0, 95% CI: 1.9–2.1). In conclusion, our findings support the long-term negative impact of CA on mental health, regardless of developmental period of exposure. Given that experience of CA is common, efforts should be put to alleviate the burden of childhood adversities for children, particularly among the most disadvantaged.     

骨应力性塑形改建的研究及其对新兵基础训练的指导意义

分组模拟训练的２８８只兔股骨标本病理观察及扭断试验结果表明,较大强度和时限训练的主导作用是加速骨塑形改建,增强抗骨折能力。分３组经３种方法训练的１８０只大鼠的胚骨上段病理切片及电镜观察表明,强化循环训练组的改建完成率（４１．７％）高于其它两组（２６．１％,２１．９％）,而应力性骨折发生率（１１．５％）则低于其它两组（２２．９％,１８．８％）。对１１２９名新兵１２周基础训练的前瞻性流行病学调查证实,下肢长管状骨经历约９周的应力性塑形改建期,训练的第２、７周出现的应力性骨折高发的双峰现象可随训练强度与时限的加大或减少,而提前或延迟出现。在训练中采用“强化循环训练法”将加速骨的塑形改建及降低应力性骨折发生率。     

Comparison of methicillin-resistant and methicillin-sensitive Staphylococcus aureus bacteremia

Methicillin-resistant Staphylococcus aureus (MRSA) has become endemic in Detroit, accounting for 50% of bacteremias in heroin abusers. To identify the salient epidemiologic and clinical features of MRSA bacteremia, case-control studies were performed comparing 28 cases of MRSA bacteremia to 28 cases of methicillin-sensitive S. aureus (MSSA) bacteremia in intravenous drug abusers. Infective endocarditis was diagnosed in 46.4% (13 of 28). In endocarditis and nonendocarditis bacteremia alike, the duration of fever, length of hospitalization, need for surgery, and mortality rates were similar. A history of recent antimicrobial therapy, especially cephalosporins, was more common in the MRSA group (p = 0.006). Complications including neurologic, renal, vascular, and musculoskeletal manifestations were more common in the MSSA endocarditis patients than MRSA endocarditis patients, although this difference was not significant. Complications related to antibiotic therapy were similar for both groups. The case-control studies indicate that MRSA and MSSA are similar in their virulence as measured by duration of hospitalization, duration of fever, complications, and mortality.

Epidemiology of posttransplant lymphoproliferative disorders in adult kidney and kidney pancreas recipients: report of the French registry and analysis of subgroups of lymphomas

A registry of posttransplant lymphoproliferative disorders (PTLD) was set up for the entire population of adult kidney transplant recipients in France. Cases of PTLD were prospectively enrolled between January 1, 1998, and December 31, 2007. Ten-year cumulative incidence was analyzed in patients transplanted after January 1, 1989. PTLD risk factors were analyzed in patients transplanted after January 1, 1998 by Cox analysis. Cumulative incidence was 1% after 5 years, 2.1% after 10 years. Multivariate analysis showed that PTLD was significantly associated with: older age of the recipient 47-60 years and >60 years (vs. 33-46 years, adjusted hazard ratio (AHR) = 1.87, CI = 1.22-2.86 and AHR = 2.80, CI = 1.73-4.55, respectively, p < 0.0001), simultaneous kidney-pancreas transplantation (AHR = 2.52, CI = 1.27-5.01 p = 0.008), year of transplant 1998-1999 and 2000-2001 (vs. 2006-2007, AHR = 3.36, CI = 1.64-6.87 and AHR = 3.08, CI = 1.55-6.15, respectively, p = 0.003), EBV mismatch (HR = 5.31, CI = 3.36-8.39, p < 0.001), 5 or 6 HLA mismatches (vs. 0-4, AHR = 1.54, CI = 1.12-2.12, p = 0.008), and induction therapy (AHR = 1.42, CI = 1-2.02, p = 0.05). Analyses of subgroups of PTLD provided new information about PTLD risk factors for early, late, EBV positive and negative, polymorphic, monomorphic, graft and cerebral lymphomas. This nationwide study highlights the increased risk of PTLD as long as 10 years after transplantation and the role of cofactors in modifying PTLD risk, particularly in specific PTLD subgroups.
