Triplet morbidity and mortality in a large case series.   总被引:1,自引:0,他引:1  
OBJECTIVE: A significant increase in the triplet birth rate has occurred recently. This rise is of concern, as these infants are historically reported to be at risk of adverse outcome. Thus, we examined the outcome of triplet births in a large contemporary case series. STUDY DESIGN: Since 1993, detailed clinical data have been collected on all patients admitted to our Neonatal Intensive Care Unit. We retrospectively analyzed this database to examine triplet outcome. RESULTS: A total of 51 consecutive sets of triplets were born over a 9-year period. The mean birth weight for triplets was 1789+/-505 g, mean gestational age was 32.6+/-2.7 weeks, with discordancy present in 17.6% of neonates. Complications of prematurity were infrequent. Triplet survival to discharge was 96%. CONCLUSIONS: This large contemporary case series of triplets demonstrates excellent survival with low associated morbidity. These data suggest that there may no longer be medical justification for offering selective fetal reduction to parents with triplet pregnancies.  相似文献

Abnormal coagulation studies indicative of a dysfibrinogen were found in the plasma of four of seven patients with malignant hepatoma. The abnormal fibrinogen was characterized by prolonged prothrombin, thrombin and reptilase times and inhibition of the coagulation of normal plasma. Purified fibrinogen revealed abnormalities similar to those in plasma. The functional defect was one of delayed polymerization of the fibrin monomer. The carbohydrate content of the abnormal fibrinogen was increased, and this change was related to the abnormal fibrinogen function. Enzymatic cleavage of sialic acid from the abnormal fibrinogen restored fibrinogen function to normal. This hepatoma-associated dysfibrinogen (acquired dysfibrinogenemia) is similar in many respects to fetal fibrinogen and may represent the presence of a fetal form of fibrinogen in hepatoma.  相似文献

Whether fruit, vegetable, and antioxidant micronutrient consumption is associated with a reduction in breast cancer incidence remains unresolved. To address this issue, we analyzed data from a large population-based case-control study, with consideration given to whether the associations varied with menopausal status or with clinical characteristics of the cases' disease. Study participants completed a modified Block food frequency questionnaire, which included assessment of the frequency and portion sizes of 13 fruits and fruit juices and 16 vegetables and the use of multiple and single vitamin supplements. Statistical analyses were done on 1,463 cases and 1,500 controls. Among postmenopausal women, reduced odds ratios [OR; 95% confidence intervals (95% CI)] were noted for the highest fifth, as compared with the lowest fifth, of intake of any vegetables [0.63 (0.46-0.86); P for trend < 0.01] and leafy vegetables [0.66 (0.50-0.86); P for trend = 0.03] after controlling for age and energy intake. Adjusted ORs (95% CIs) were also decreased for postmenopausal breast cancer in relation to high intake of carotenoids, alpha-carotene, beta-carotene, lutein, and particularly lycopene [0.66 (0.48-0.90); P for trend = 0.03]. Inverse associations for fruits and vegetables were stronger for postmenopausal women with estrogen receptor (ER)+ tumors (OR, 0.65; 95% CI, 0.51-0.82) than ER- tumors (OR, 0.92; 95% CI, 0.64-1.32), but results were less consistent for micronutrients. No similarly reduced associations were observed among premenopausal women. ORs did not appreciably differ by in situ or invasive breast cancer or by whether cases had begun chemotherapy. Our results support an inverse association for fruit and vegetable intake among postmenopausal but not premenopausal breast cancer, which may be more pronounced among women with ER+ tumors.  相似文献

Quality of life among younger women with breast cancer.   总被引:16,自引:0,他引:16  
PURPOSE: To describe quality of life (QOL) of younger women 4 to 42 months after breast cancer diagnosis and to identify factors associated with impaired QOL. METHODS: A total of 202 women diagnosed with stage I to III breast cancer at age 50 or younger from 4 to 42 months after breast cancer diagnosis previously completed a mailed survey. Global QOL; health-related QOL as measured by the Functional Assessment of Cancer Therapy-Breast Cancer (FACT-B); medical history; symptoms; days of work/activity missed after diagnosis; relationship, sexual, and body image problems; coping strategies; and feelings of preparedness were measured. RESULTS: General aches and pains and unhappiness with appearance were reported by more than 70% of women. Hot flashes (P = .0007), pain with sexual intercourse (P = .02), and difficulty with bladder control (P = .002) all significantly increased with age. Global QOL was significantly lower than for a nonpatient sample of younger women (P < .0001). In general, few sociodemographic and medical factors were related to QOL. In multivariate analyses, days of work/usual activity missed immediately after diagnosis; relationship, sexual, or body image problems after diagnosis; and coping strategies were related to almost all QOL domains. Ongoing treatment, vaginal dryness, and feeling unprepared for the impact of breast cancer were related to some domains. CONCLUSION: Younger breast cancer survivors are at risk for impaired QOL up to several years after diagnosis. Younger women, especially those at high risk for lower QOL, may need interventions that specifically target their needs related to menopausal symptoms and problems with relationships, sexual functioning, and body image. Preparing younger woman for the impact of breast cancer may also prove beneficial.  相似文献

Social context plays a significant role in adolescent identity development, particularly for youth lacking traditional systems of support. Using ecological and symbolic interactionism perspectives, this study qualitatively explored the psychosocial identity development of Black gay, bisexual, or transgendered youth participating in the House Ball Community (HBC). The HBC is a diverse network of family-like structures called ‘houses’, as well as a glamorous social outlet via pageant-like ‘balls’ in which participants compete. A series of focus groups were conducted with youth and leaders from the HBC (n?=?37; age range?=?17–24). Via cross-case and comparative analyses, specific motivating factors related to entry into and continued involvement in the community were identified. Factors related to entry into the community included lack of safe spaces, opportunities for acceptance, means of subsistence, and allure of the scene. Factors related to continued involvement included resilience and coping skills development, sexual identity acceptance and pride, prevalence of risky behaviour, and risk of exploitation. Discussion of these factors provides insight on how self-constructed, supplementary social contexts may provide both unique supports and risks to members, allowing for more focused and well-informed interventions and policies to enhance healthy development in such communities while mitigating risk.  相似文献

Background

Early in medical education, physicians must develop competencies needed for tobacco dependence treatment.

Objective

To assess the effect of a multi-modal tobacco dependence treatment curriculum on medical students’ counseling skills.

Design

A group-randomized controlled trial (2010–2014) included ten U.S. medical schools that were randomized to receive either multi-modal tobacco treatment education (MME) or traditional tobacco treatment education (TE).

Setting/Participants

Students from the classes of 2012 and 2014 at ten medical schools participated. Students from the class of 2012 (N?=?1345) completed objective structured clinical examinations (OSCEs), and 50 % (N?=?660) were randomly selected for pre-intervention evaluation. A total of 72.9 % of eligible students (N?=?1096) from the class of 2014 completed an OSCE and 69.7 % (N?=?1047) completed pre and post surveys.

Interventions

The MME included a Web-based course, a role-play classroom demonstration, and a clerkship booster session. Clerkship preceptors in MME schools participated in an academic detailing module and were encouraged to be role models for third-year students.

Measurements

The primary outcome was student tobacco treatment skills using the 5As measured by an objective structured clinical examination (OSCE) scored on a 33-item behavior checklist. Secondary outcomes were student self-reported skills for performing 5As and pharmacotherapy counseling.

Results

Although the difference was not statistically significant, MME students completed more tobacco counseling behaviors on the OSCE checklist (mean 8.7 [SE 0.6] vs. mean?8.0 [SE 0.6], p?=?0.52) than TE students. Several of the individual Assist and Arrange items were significantly more likely to have been completed by MME students, including suggesting behavioral strategies (11.8 % vs. 4.5 %, p?<?0.001) and providing information regarding quitline (21.0 % vs. 3.8 %, p?<?0.001). MME students reported higher self-efficacy for Assist, Arrange, and Pharmacotherapy counseling items (ps?≤0.05).

Limitations

Inclusion of only ten schools limits generalizability.

Conclusions

Subsequent interventions should incorporate lessons learned from this first randomized controlled trial of a multi-modal longitudinal tobacco treatment curriculum in multiple U.S. medical schools.NIH Trial Registry Number: NCT01905618

Malignant cells from four patients with acute promyelocytic leukaemia (APL) were analysed for coagulant and fibrinolytic activity. For comparison polymorphonuclear leucocytes from normal donors and myeloblasts from patients with acute myelogenous leukaemia (AML) were also tested. The APL cells compared to the other cells consistently shortened the recalcification time and partial thromboplastin time of normal, factor VIII deficient and factor IX deficient plasma, but had no effect on factor X deficient or factor VII-X deficient plasma. APL cells demonstrated increased (250–1500%) tissue factor activity when tested in a two-stage assay in which tissue factor is the rate limiting component. The increased tissue factor activity was primarily found in the granular fraction of APL cells. Fibrinolytic and proteolytic activity of the APL cells was variable. Cells from three of the APL patients demonstrated a slight increase (150–400%), while the cells from one APL patient had markedly diminished proteolytic activity. The increased fibrinolytic activity was associated primarily with the granular fraction. Although the fibrinolytic activity is increased, it does not parallel the increase in tissue factor activity. This imbalance of coagulation and fibrinolysis in the cellular composition of promyelocytes could explain the high incidence of clinical thrombo-haemorrhagic disorders related to intravascular coagulation in APL.  相似文献
