Anxiety symptoms and disorders at eight weeks postpartum

Although the prevalence, risk factors for, and consequences of postpartum depression have been studied extensively, little work has examined the nature of postpartum anxiety disorders in community samples. In the present study, 147 community women completed a diagnostic interview and a battery of self-report inventories approximately eight weeks after childbirth. The rate of generalized anxiety disorder was elevated as compared to the rate in women representative of the general population. Depending on the particular domain of anxiety being considered, 10-50% of women reporting anxiety symptoms endorsed comorbid depressive symptoms. In hierarchical multiple regression analyses, different combinations of demographic and vulnerability variables predicted symptoms of somatic anxiety, social anxiety, and depression, although there were no significant predictors of worry symptoms. In addition, number of children, depression, and social anxiety predicted postpartum relationship distress. These results suggest that postpartum anxiety disorders are more common than postpartum depression and worthy of systematic study.     

The use of a combination of galectin-3 and thyroid peroxidase for the diagnosis and prognosis of thyroid cancer

In this retrospective histologic study, galectin-3 had a sensitivity of 92% (22/24) for papillary thyroid carcinoma and 44% (4/9) for follicular thyroid carcinoma. Thyroid peroxidase (TPO) had a sensitivity of 50% (12/24) for papillary and 11% (1/11) for follicular carcinoma. The combination of galectin-3 and TPO had a sensitivity of 96% (23/24) for papillary and 44% (4/9) for follicular carcinoma. From a prognostic standpoint, of patients whose papillary carcinomas expressed both markers, all became free of disease. Of those whose papillary carcinomas expressed galectin-3 but not TPO, 57% (4/7) became free of disease, 29% (2/7) had persistent disease, and 14% (1/7) had progressive disease. This study confirms previous observations that galectin-3 alone is highly sensitive for papillary carcinoma but not adequately sensitive for follicular carcinoma. TPO alone is not adequately sensitive for the evaluation of any thyroid lesion. The combination of galectin-3 and TPO is complementary as a diagnostic and prognostic tool for patients with papillary carcinoma.     

Ethics in nursing homes: experience and casuistry

The purpose of the study was to further explore the methods that nurses use to solve ethically difficult care situations in nursing homes while the aim of this article was to present a model for nursing practice in such situations. Fourteen nurses from three nursing homes in Norway were observed and interviewed in order to discern the strategies they used to deal with ethically difficult care situations. To analyse this information, we used a constant comparative method until a grounded theory emerged. The nurses' principal strategy was to apply earlier experiences while striving for the best outcome for the elderly patients. This article discusses this strategy and compares it to a theory of ethics called casuistry. We suggest that by using the method of experiences combined with casuistry in a more systematic way, nurses can develop acceptable solutions for difficult care situations in nursing homes.     

Role of routine ultrasonography in monitoring the outcome of medical abortion in a clinical setting

BACKGROUND: Clinical methods generally used to evaluate the completeness of medical abortion are not accurate. There are no published reports evaluating the role of routine ultrasonography in monitoring the outcome of medical abortion. The purpose of this study was to investigate whether routine transvaginal ultrasonography (TVS) at the follow-up visit after medical abortion can accurately identify women who will require surgical intervention. DESIGN: Retrospective review of medical records and charts of all women undergoing medical abortion in the first trimester of pregnancy between January 1999 and December 2001. METHODS: Medical abortion was performed using oral mifepristone and a vaginal prostaglandin analog before 63 days gestation. All women had an initial TVS to confirm intrauterine pregnancy and gestational age, and another TVS at the follow-up visit 2-3 weeks later to assess the completeness of abortion. Surgical evacuation of the uterus was allowed as indicated on clinical grounds but not on the basis of ultrasound findings only. RESULTS: A total of 690 women consented to medical abortion during the study period. Eleven of these women were excluded from the study for various reasons. Of the remaining 679 cases, 95% (645/679) had a documented follow-up at the hospital. The pregnancy termination rate among these women was 99.2% (640/645) and TVS identified all five cases of continuing pregnancy at the follow-up. A total of 66 (10.2%) patients had complications. The uterine cavity was empty on TVS at the follow-up visit in 84.8% (547/645) of cases and only 3.1% (17/547) of them required surgical aspiration/curettage due to excessive or prolonged vaginal bleeding. In the remaining 15.2% (98/645) the uterine cavity was not empty, and 43.9% (43/98) of them had a curettage. The risk of requiring a surgical intervention was significantly higher [odds ratio (OR) 24.4; 95% confidence interval (95% CI) 14.9-39.7] when the uterine cavity was not demonstrated to be empty at the follow-up visit 2-3 weeks after medical abortion. However, 59.1% (55/93) of women did not require surgical intervention despite ultrasound evidence of thick endometrial echo-complex. CONCLUSION: Routine TVS 2-3 weeks after medical abortion appears to be an efficient means of accurately identifying the cases of ongoing pregnancy and diagnosing a complete abortion. Although TVS could be used as an adjunct to clinical examination to diagnose an incomplete expulsion, it does not accurately differentiate those women who require surgical intervention from those who do not.     

Age, sexual behavior and human papillomavirus infection in oral cavity and oropharyngeal cancers

There are few well-established patient risk factors associated with human papillomavirus (HPV) infection in cancers of the oral cavity and oropharynx. The purpose of this study was to determine if there were significant different risk factors and tumor characteristics between HPV-positive and HPV-negative cancer cases. HPV was evaluated in cancer tissue and exfoliated oral cells of 193 oral cavity/oropharynx cancer patients using PCR and direct DNA sequencing. A patient questionnaire collected information about risk factors, sexual practices and medical history. The prevalence of HPV high-risk (HR) types was 20% in cancer cases. Three types were identified: HPV-16 (87%), HPV-18 (3%) and HPV-33 (11%). Risk factors for HPV-HR included younger age (< or = 55 years vs. > 55 years; adjusted OR = 3.4; 95% CI = 1.6-7.3) and younger-age cases who had more lifetime sex partners (adjusted OR = 3.8; 95% CI = 1.4-10.1), practiced oral-genital sex (adjusted OR = 4.3; 95% CI = 1.8-10.4) or oral-anal sex (adjusted OR = 19.5; 95% CI = 3.4-113). Compared to HPV-negative cancers, HPV-HR cancers were more likely to have a positive HPV-HR exfoliated oral cytology test (adjusted OR = 7.8; 95% CI = 3.4-18.4), later stage (adjusted OR = 3.0), nodal involvement (adjusted OR = 4.1) and advanced grade (adjusted OR = 3.0). This study shows new evidence that the prevalence of oncogenic mucosal HPV is higher in younger-age oral cavity/oropharynx cancer cases whose sexual practices are typically associated with sexual transmission of the virus. HPV detection also appears to be an indicator of advanced disease characteristics that may require different clinical treatment for this subset of patients. An exfoliated oral cytology test for HPV was a significant predictor of HR types in the cancers, suggesting that an oral rinse may provide an early biomarker of infected tumors.     

The influence of ciclosporine A on the vasoactive effects of serotonin in in vitro perfused human umbilical arteries

BACKGROUND: Pregnancy is feasible in organ-transplanted women, but little is known about possible effects of ciclosporine A on the circulation in the fetus and placenta. AIM: To investigate the influence of ciclosporine A (CsA) on the vasoactive effects of serotonin in human umbilical arteries. STUDY DESIGN AND SUBJECTS: In vitro perfusion was performed in umbilical cord segments from seven organ-transplanted patients on CsA based immunosuppression and in 17 cords from uncomplicated pregnancies. Serotonin was administered in stepwise increasing concentrations from 10(-10) to 10(-5) M. In preparations from normal pregnancies, serotonin 10(-7) M, was administered before and 30 min after the start of a continuous CsA infusion (1.0 mg/l). The influence of CsA 0.1 or 1.0 mg/l on the basal, unstimulated perfusion pressure was investigated in separate experiments. OUTCOME MEASURES: Changes in perfusion pressure due to constrictory or dilatatory responses. RESULTS: In all preparations from the organ-transplanted patients, serotonin induced a constrictory response that was non-significantly lower than that observed in the control group. The frequency of a dilatatory response preceding the vasoconstriction was 3/7 and 12/17 (non-significant) in the CsA-treated and control groups, respectively. In the experiments with CsA administration, a non-significant increase in the constrictory serotonin response was observed as compared to the control experiments. CsA did not alter the basal, unstimulated perfusion pressure. CONCLUSION: CsA did not have any significant influence on the vasoactive effect of serotonin in human umbilical arteries perfused in vitro.     

Comparison of functional immune responses in humans after intranasal and intramuscular immunisations with outer membrane vesicle vaccines against group B meningococcal disease

A serogroup B meningococcal outer membrane vesicle (OMV) vaccine was delivered either intranasally or intramuscularly to 12 and 10 volunteers, respectively. The mucosal vaccine was given as four weekly doses followed by a fifth dose after 5 months; each dose consisted of OMVs equivalent to 250 microg of protein. The intramuscular (i.m.) vaccine, consisting of the same OMVs but adsorbed to Al(OH)(3), was administered as three doses each of 25 microg of protein, with 6 weeks interval between first and second doses and the third dose after 10 months. Both groups of vaccinees demonstrated significant immune responses when measured as specific IgG antibodies against live meningococci, as serum bactericidal activity (SBA) and as opsonophagocytic activity. Two weeks after the last dose, the anti-meningococcal IgG concentrations were significantly higher in the i.m. group (median IgG concentration: 43.1 microg/ml) than in the intranasal group (10.6 microg/ml) (P=0.001). The corresponding opsonophagocytic activity was 7.0 and 3.0 (median log(2) titre) (P=0.001), and the SBA was 5.0 and 2.0 (median log(2) titre) (P=0.005), for the i.m. and intranasal groups, respectively. The last immunisation induced an enhanced immune response in the i.m. group, whereas the intranasal group showed no significant booster response. Accordingly, affinity maturation of anti-OMV-specific IgG antibodies was seen only after i.m. vaccination. The IgG1 subclass dominated the responses in both groups, whereas the significant IgG3 responses observed in the i.m. group were absent in the intranasal group. Although the intranasal OMV vaccination schedule used here induced functional immune responses relevant to protection, an improved vaccine formulation and/or a modified mucosal immunisation regimen may be needed to achieve a systemic effect comparable to that seen after three doses of intramuscular vaccination.
