全身运动质量评估指导高危儿早期干预的研究

目的 通过比较全身运动(GMs)评估正常的高危儿单纯家庭康复训练与家庭康复训练联合药物干预的预后,分析GMs对高危儿早期干预的指导意义。方法 选取2016年2月-2017年2月于潍坊市妇幼保健院康复科就诊并接受GMs评估正常的183例高危儿,随机分组为观察组和对照组,观察组为单纯家庭康复训练组89例,对照组为家庭康复训练联合药物干预组94例。采用Peabody运动发育量表对两组患儿分别于纠正月龄6、9、12个月龄进行评估,对Peabody运动发育量表中各指标应用SPSS 21.0进行统计分析。结果 干预后,纠正月龄6、9、12个月龄时,观察组和对照组Peabody运动发育量表中粗大运动商(GMQ)、精细运动商(FMQ)、总运动商(TMQ)比较,差异无统计学意义(P>0.05),重复测量方差分析发现观察组和对照组的GMQ、FMQ、TMQ评分的组间效应差异无统计学意义(P>0.05),时间效应差异有统计学意义(P<0.05),干预因素与时间因素不存在交互作用(P>0.05)。结论 GMs评估对高危儿早期干预具有指导意义。GMs评估正常者,家庭康复训练可达到促进高危儿运动功能发育的目的 ,避免仅因系高危儿而采取“过度干预”。     

高危患者降压治疗:重视控制血压底线

高血压高危患者的降压治疗既需降低血压，又需保持足够血流以保障器官灌注。血压降低过度无疑也有一定风险，因此控制皿压需要底线。高危高血压患者的个体差异大，在降压治疗过程中，临床医生既要以循证医学为鉴，叉须遵循个体化治疗原则，把握好降压幅度和速度，坚持高质量平稳降压，才能更好地保护靶器官，减少心脑血管意外的发生。     

Lead poisoning in precious metals refinery assayers: A failure to notify workers at high risk

Lead poisoning in a precious metals refinery fire assayer and a routine OSHA inspection prompted an investigation of the index facility, a survey of the industry, and efforts to notify assayers of this previously unrecognized hazard. Air and blood samples were obtained at the index facility. Management personnel from all fire assay laboratories in Rhode Island and southern Massachusetts were interviewed. The industry's trade association, OSHA, NIOSH, trade unions, and the media were asked to assist in a nationwide notification effort. Assayers at the index facility had excessive exposures to lead due to an age-old, lead-based assaying method that remains the industry gold standard. Blood lead levels of the three assayers (mean 61.3 μ/dl, range 48–86 μg/dl) were considerably higher than those of 16 other refinery workers (mean 27.4 μg/dl, range 13–49 μg/dl). The industry survey revealed inadequate knowledge of both the lead hazard and the applicability of the OSHA lead standard. Notification efforts failed in large part due to economic obstacles. The notification of workers at high risk of lead exposure and the eradication of occupational lead poisoning will require greater attention to economic forces. © 1994 Wiley-Liss, Inc.     

肿瘤高危人群的流式细胞术、内窥镜和病理检查的对比研究

本文对上消化道肿瘤高发区经初筛的１２０例高危人群粘膜组织做了流式细胞ＤＮＡ含量、内窥镜和组织病理学检查的对比研究。其结果显示的肿瘤阳性检出率分别为２７．５％、６．７％和１４．０％。对内窥镜诊断为不同胃疾病患者的流式细胞术分析发现，流式细胞术阳性检出率，胃癌组为７５．０％，萎缩性胃炎组为２８．３％，浅表性胃炎组为７．１％，正常粘膜组为０％。ＤＩ值均值，炎症组（萎缩性胃炎和浅表性胃炎）患者与正常对照组接近，而癌组则明显升高。增殖指数和Ｓ期细胞比例，从正常对照→浅表性胃炎→萎缩性胃炎→胃癌组，呈递增变化，而且各组间有显著差异。     

Amputation in elderly and high-risk vascular patients

Fifty-eight patients underwent lower limb amputation for arterial disease over a 30-month period. Mean age of the patients was 72 years. Cardiopulmonary and metabolic risk factors were present in the majority of the patients. Postoperative one-year and three-year mortality rates were 24, 40, and 76%, respectively. Contralateral amputation was required in one-third of the patients after a mean period of eight months. Only younger and healthier patients returned to a meaningful social life after appropriate prosthetic fitting. In view of the high mortality and morbidity rates, above-knee amputation seems a better choice than below-knee amputation in these elderly and high-risk patients.     

Staged Fontan procedure for mitral atresia associated with severe tricuspid regurgitation, pulmonary hypertension, and pulmonary artery distortion

Optimal initial palliation and a subsequent staged approach is mandatory for high-risk Fontan candidates. We describe the case of mitral atresia with severe tricuspid regurgitation and pulmonary hypertension successfully managed by repeated palliation from the neonatal period and 2-stage Fontan surgery. A 1-month-old boy diagnosed with mitral atresia and double-outlet right ventricle underwent pulmonary artery banding at 1 month of age, followed by repeated pulmonary artery banding accompanied by tricuspid annuloplasty and atrial septal defect enlargement at 6 months. Because of the presence of pulmonary artery distortion, right ventricular dysfunction, and borderline pulmonary vascular resistance, a hemi-Fontan procedure was conducted with extended pulmonary artery plasty when the boy was 3 years and 8 months old. Cardiac catheterization done 3 months after showed improvement in risk factors, and the final Fontan operation (total cavopulmonary connection) was successfully done in conjunction with repeated tricuspid annuloplasty when the boy was 4 years and 5 months old. The patient remains in excellent clinical condition at the last follow-up 5 years after the final Fontan procedure with sinus rhythm and good ventricular function.     

Potential Association between Zika Infection and Microcephaly during 2007 Fever Outbreak,Gabon

Although Zika virus (ZIKV) circulates in sub-Saharan Africa, no case of ZIKV-associated microcephaly has thus far been reported. Here, we report evidence of a possible association between a 2007 outbreak of febrile illness and an increase in microcephaly and possibly ZIKV infection in Gabon.     

Convergent and Discriminant Validity of the Perinatal PTSD Questionnaire (PPQ): A Preliminary Study

We evaluated the validity of the Perinatal Posttraumatic Stress Disorder Questionnaire (PPQ) as a measure of posttraumatic stress symptomatology. Mothers of high-risk infants (N = 91) and healthy, full-term infants (N = 51) answered the PPQ and two other convergent measures of posttraumatic stress disorder symptoms, the Impact of Event Scale (IES) and the Penn Inventory (PI). The Need for Cognition Scale (NCS) was used as a divergent measure. Correlations among the convergent measures were significantly greater than the correlation between the PPQ and NCS. High-risk mothers also scored higher than normal mothers on the PPQ and IES. The results support the validity of the PPQ.     

Rapid repeat pregnancy and experiences of interpersonal violence among low-income adolescents

CONTEXT: Rapid repeat pregnancy (RRP) among adolescents, usually defined as pregnancy onset within 12-24 months of the previous pregnancy outcome, has frequently been the target of public health interventions, due to the exacerbation of negative consequences associated with recurrent adolescent pregnancy (and more specifically with childbearing). OBJECTIVE: To examine what, if any, relationship exists between RRP and the experience of interpersonal violence and abuse among low-income adolescents at one semi-urban health center. DESIGN: Case-control study using retrospective chart review. PARTICIPANTS AND SETTING: 100 women aged 13-21 who received prenatal care at one independent nonprofit health center that serves adolescents and their children from June 1994 through June 1996. MAIN OUTCOME MEASURES: Number and timing of pregnancies, occurrence of physical or sexual abuse; other psychosocial risk factors were evaluated. RESULTS: In this population, the experience of any form of physical or sexual violence during the study interval was associated with RRP within 12 months (p = 0.01, OR = 3.46) and 18 months (p = 0.013, OR = 4.29). Other previously reported predictors of RRP, including family stress, financial stress, and other environmental stressors did not reach statistical significance at either 12 months or 18 months in this sample. Of additional note, young women who experienced any form of abuse during the 12-month study interval were substantially more likely to miscarry than were their nonabused peers, and spontaneous abortion was also very strongly associated with RRP (p < 0.00001; OR = 22.6). CONCLUSIONS: The experience of interpersonal violence is correlated with rapid repeat pregnancy among low-income adolescents. This study strongly suggests a need for both extensive screening for partner and family violence among pregnant and postpartum adolescents, and follow-up safety planning support in combination with family planning interventions.
