Journal compilation © 2010 John Wiley & Sons A/S. Objectives: Persistently impaired psychosocial functioning has been recognized in many individuals with bipolar disorder. However, existing measures of functional disability have been adapted for use in bipolar disorder based mainly on those developed for use in other conditions. The present study involved the development and validation of a new patient self‐report measure specific to bipolar disorder, the Bipolar Functional Status Questionnaire (BFSQ). Methods: Relevant constructs were identified, evaluated, and refined through an expert advisory panel in conjunction with patient interviews. Questionnaire items were vetted through iterative patient interviews. Psychometric properties were determined based on patient responses from implementation of the proposed 33‐item questionnaire in an 11‐site study of 596 patients with bipolar disorder across varied phases of illness. Results: Eight constructs were identified as fundamental to functional status in bipolar disorder: cognitive function, sleep, role functioning, emotional functioning, energy/vitality, social functioning, personal management, and sexual functioning. Psychometric validation supported item reduction to a 24‐item unidimensional scale, with high internal consistency (coefficient α’s = 0.93–0.95), high test‐retest reliability (intraclass correlation coefficient = 0.86, 95% confidence interval = 0.82–0.89), strong convergent validity with other functional disability measures (r’s > 0.70), and highly significant discriminant validity across illness phases, with large effect sizes (Cohen’s d > 0.70). Conclusions: The BFSQ is a psychometrically sound self‐report measure that can be used to effectively quantify functional status across different clinical states in patients with bipolar disorder.     

高效液相色谱法同时测定五加中剌五加苷B、苷E的含量

目的测定甘肃产五加中剌五加苷B、苷E的含量。方法高效液相色谱法,ODSKromasal柱。水乙晴(955)为流动相,检测波长222nm,柱温度25℃。结果本文可同时测定剌五加苷B、苷E的含量。剌五加苷B、苷E分别在0.064～0.320μg/ml;0.074～0.370μg/ml范围内峰面积与浓度呈线性关系,平均回收率分别为102.5%,RSD=4.2%,95.5%,RSD=4.6%。结论剌五加苷B、苷E在红毛五加中含量最高;茎皮中含量最高;剌五加苷E的含量高于苷B。     

Childhood cardiac function after twin-to-twin transfusion syndrome – a 10-year follow up

Aim:  To perform a 10-year follow up of cardiac structure and function after twin-to-twin transfusion syndrome (TTTS) – a severe foetal circulatory complication associated with myocardial hypertrophy in the recipient twin.
Methods:  Cardiac dimensions, systolic and diastolic function as assessed by echocardiography including flow and tissue Doppler velocimetry in 22 healthy survivors of TTTS with a mean age of 9.6 (7.2–11.8) years.
Results:  The donor and recipient twin did not show any differences in end-diastolic ventricular size, interventricular septum thickness, diameter of right ventricular outflow tract, cardiac valves, coronary arteries or in systolic blood flow velocities. However, compared with the donors, the recipients had significantly lower E/A ratios because of lower E-waves in both mitral (−0.15 ± 0.10, p < 0.01) and tricuspid (−0.09 ± 0.07, p < 0.01) valves, indicating reduced early diastolic ventricular fillings compared with donors.
Conclusion:  At school age, twins surviving TTTS had a cardiac structure and function within normal range. There were no differences in heart structure or systolic ventricular function between twins but, compared with the donor twin, we found a reduced early diastolic function in the recipient.     

Vital initiation of pregnancy (VIP) using human menopausal gonadotropin and human chorionic gonadotropin ovulation induction: phase II--1981

In a program for in vitro fertilization, laparoscopies for oocyte aspiration were performed on 24 patients receiving human menopausal gonadotropin and human chorionic gonadotropin. Of the 40 preovulatory oocytes that were recovered from these patients, 33 (83%) were fertilized and 30 (75%) cleaved and were transferred. Ten immature oocytes were collected, and attempts were made to mature these in vitro prior to insemination. All ten oocytes (100%) did fertilize, and seven (70%) cleaved and were transferred. Morphologic variation was noted between cleaving conceptuses, even in those conceptuses responsible for establishing pregnancies. Five pregnancies resulted from 19 embryo transfers (26%).     

Nurses' perceived barriers to the implementation of a Fall Prevention Clinical Practice Guideline in Singapore hospitals

Background  

Theories of behavior change indicate that an analysis of barriers to change is helpful when trying to influence professional practice. The aim of this study was to assess the perceived barriers to practice change by eliciting nurses' opinions with regard to barriers to, and facilitators of, implementation of a Fall Prevention clinical practice guideline in five acute care hospitals in Singapore.
