Effect of pregnancy and birth on the course of myasthenia gravis before or after transsternal radical thymectomy

OBJECTIVE: Myasthenia gravis (MG) affects women at childbearing age. Therefore, the question arises if these patients should become pregnant and if thymectomy has a positive effect on the course of MG in pregnant patients. METHODS: Fifteen pregnancies had been followed retrospectively. All patients underwent transsternal radical thymectomy for MG. The course of MG in the period before, during, and after the pregnancy was scored according to Ossermann's classification. The effect of thymectomy on delivery and on the newborns was evaluated. RESULTS: Patients were divided in two groups: pregnancies before (group I, n=8) and after (group II, n=7) thymectomy. During pregnancy, in group I, one deterioration was observed and in seven patients the disease was unchanged. In group II, one deterioration, five unchanged courses, and one improvement were observed. In the postpartum period, in group I, seven patients did not change and one improved. In group II, two deteriorations, three unchanged courses, and two improvements were observed. Before pregnancy, group II patients were in a better Ossermann stage in comparison with those in group I. Eight of the 12 deliveries were spontaneous (three abortus). Myasthenic symptoms were observed in two newborns in group I. CONCLUSION: Our data suggest that MG is not prohibitive to have children. The course of MG after transsternal radical thymectomy is often ameliorated. A better MG-stage, reached after thymectomy, before pregnancy seems to be correlated with a better course during pregnancy.

Effectiveness of chlamydia screening: systematic review

BACKGROUND: Screening programmes are promoted to control transmission of and prevent female reproductive tract morbidity caused by genital chlamydia. The objective of this study was to examine the effectiveness of register-based and opportunistic chlamydia screening interventions. METHODS: We searched seven electronic databases (Cinahl, Cochrane Controlled Trials Register, DARE, Embase, Medline, PsycINFO and SIGLE) without language restrictions from January 1990 to October 2007 and reference lists of retrieved articles to identify studies published before 1990. We included studies examining primary outcomes (pelvic inflammatory disease, ectopic pregnancy, infertility, adverse pregnancy outcomes, neonatal infection, chlamydia prevalence) and harms of chlamydia screening in men and non-pregnant and pregnant women. We extracted data in duplicate and synthesized the data narratively or used random effects meta-analysis, where appropriate. RESULTS: We included six systematic reviews, five randomized trials, one non-randomized comparative study and one time trend study. Five reviews recommended screening of women at high risk of chlamydia. Two randomized trials found that register-based screening of women at high risk of chlamydia and of female and male high school students reduced the incidence of pelvic inflammatory disease in women at 1 year. Methodological inadequacies could have overestimated the observed benefits. One randomized trial showed that opportunistic screening in women undergoing surgical termination of pregnancy reduced post-abortal rates of pelvic inflammatory disease compared with no screening. We found no randomized trials showing a benefit of opportunistic screening in other populations, no trial examining the effects of more than one screening round and no trials examining the harms of chlamydia screening. CONCLUSION: There is an absence of evidence supporting opportunistic chlamydia screening in the general population younger than 25 years, the most commonly recommended approach. Equipoise remains, so high-quality randomized trials of multiple rounds of screening with biological outcome measures are still needed to determine the balance of benefits and harms of chlamydia screening.

Anti-Müllerian hormone and inhibin B as predictors of pregnancy after treatment by in vitro fertilization/intracytoplasmic sperm injection

OBJECTIVE: To evaluate anti-Müllerian hormone (AMH) as a marker of reproductive outcome after IVF/intracytoplasmic sperm injection (ICSI). DESIGN: Longitudinal study. SETTING: University hospital. PATIENT(S): Two hundred seventy-six consecutive women undergoing IVF/ICSI. INTERVENTION(S): Ovarian stimulation, oocyte retrieval, IVF, ICSI, embryo transfer, AMH, and inhibin B determinations in serum and follicular fluid (FF). MAIN OUTCOME MEASURE(S): The AMH and inhibin B concentrations in 276 matched FF/serum pairs have been determined. Different outcome groups have been compared and set in relation to the oocyte count, morphological parameters, and steroid hormone levels. RESULT(S): The concentrations of AMH and inhibin B in both serum and FF were significantly higher in the group of women who became pregnant in the corresponding treatment cycle than in those who did not conceive. Positive correlations were observed between serum inhibin B concentrations and embryo morphology (r = 0.126, 95% confidence interval 0.026-0.284). Serum and FF AMH or inhibin B correlated positively with the oocyte count and negatively with the pretreatment cycle day 3 FSH level and the total administered gonadotropin dose. CONCLUSION(S): The AMH and inhibin B levels on the day of oocyte retrieval are correlated to reproductive outcome.

Termination of Ventricular Tachycardia with Antitachycardia Pacing after Ineffective Shock Therapy in an ICD Recipient with Hypertrophic Cardiomyopathy

Implantable Cardioverter Defibrillator (ICD) implantation is the only established therapy for primary or secondary prevention of sudden cardiac death in patients with Hypertrophic Cardiomyopathy (HCM). Ineffectiveness of shock therapy for the termination of potentially fatal ventricular arrhythmias in ICD recipients is rare in the presence of appropriate arrhythmia detection by the device. We report the case of a 48-year-old woman with HCM and a single chamber ICD, who received five inefficient high-energy (35 Joules) shocks for the termination of an appropriately detected episode of Ventricular Tachycardia (VT). The episode was safely terminated with a subsequent application of Antitachycardia Pacing (ATP) by the device. At the following ICD control, an acceptable defibrillation threshold was detected.

Role of the Central Nervous System in the Regulation of Pregnancy, Parturition and Lactation in Beef Heifers

Progesterone secretion is crucial for maintaining pregnancy to parturition in mammalian species, and in cattle the corpus luteum is the primary source of this hormone. This study determined the roles of prolactin (PRL), growth hormone (GH) and luteinizing hormone (LH) in the luteotropic process in beef heifers hypophyseal stalk-transected (HST, n = 7) or sham operated on (SOC, n = 9) during midgestation. The main finding was that endogenous PRL and GH maintained progesterone secretion in HST heifers similar to that in SOC throughout pregnancy. Serum PRL averaged 37 vs 187 and GH 2 vs 4 ng/ml in HST compared with SOC, whereas LH abruptly decreased to undetectable levels after HST compared with a modest 0A4 ng/ml in SOC heifers. The second finding was that parturition and lactation occurred in HST heifers with calf delivery induced to occur at the same time as SOC. Milk production in HST animals was severely limited, and postpartum estrus obliterated compared with SOC. The suckling stimulus sustained milk ejection in HST heifers in spite of diminished PRL and GH secretion. The results suggest that PRL, GH and possibly placental lactogen are luteotropic during pregnancy in cattle.

Ultrasound feedback and motivational interviewing targeting smoking cessation in the second and third trimesters of pregnancy.

INTRODUCTION: Cigarette smoking during pregnancy is associated with poor maternal and child health outcomes. Effective interventions to increase smoking cessation rates are needed particularly for pregnant women unable to quit in their first trimester. Real-time ultrasound feedback focused on potential effects of smoking on the fetus may be an effective treatment adjunct, improving smoking outcomes. METHODS: A prospective randomized trial was conducted to evaluate the efficacy of a smoking cessation intervention consisting of personalized feedback during ultrasound plus motivational interviewing-based counseling sessions. Pregnant smokers (N = 360) between 16 and 26 weeks of gestation were randomly assigned to one of three groups: Best Practice (BP) only, Best Practice plus ultrasound feedback (BP+US), or Motivational Interviewing-based counseling plus ultrasound feedback (MI+US). Assessments were conducted at baseline and end of pregnancy (EOP). RESULTS: Analyses of cotinine-verified self-reported smoking status at EOP indicated that 10.8% of the BP group was not smoking at EOP; 14.2% in the BP+US condition and 18.3% who received MI+US were abstinent, but differences were not statistically significant. Intervention effects were found conditional upon level of baseline smoking, however. Nearly 34% of light smokers (< or =10 cigarettes/day) in the MI+US condition were abstinent at EOP, followed by 25.8% and 15.6% in the BP+US and BP conditions, respectively. Heavy smokers (>10 cigarettes/day) were notably unaffected by the intervention. DISCUSSION: Future research should confirm benefit of motivational interviewing plus ultrasound feedback for pregnant light smokers and explore mechanisms of action. Innovative interventions for pregnant women smoking at high levels are sorely needed.

Deregulation strategies and its regulating effects: The case of the termination of Social Assistance for rejected asylum seekers in Switzerland

Deregulation strategies and their regulating effects: The case of the termination of Social Assistance for rejected asylum seekers in Switzerland. In Switzerland, rejected asylum seekers no longer have any residence rights. In 2003 the Swiss state decided to terminate the so far granted social assistance for people with a non-entry decision on their asylum request. In 2008 the termination of social assistance was expanded to all rejected asylum seekers. Nevertheless, facing the impossibility of deporting them, the Swiss state entitled this group of people to emergency assistance. It is a basic, which is stated in the Swiss Federal constitution. In this context, new structures were established specially for rejected asylum seekers. These structures had to be set up, financed, controlled, managed and legitimized. For example, collective centres were set up exclusively for rejected asylum seekers. In this speech, I want to analyze the political and bureaucratic process of terminating social assistance for rejected asylum seekers. The exclusion of rejected asylum seekers from social aid was embedded in a wider austerity program of the Federal State. The Federal Migration Office had been requested to save money. The main official goal was to reduce the support of these illegalized people, reduce any structures that would prolong their stay on Swiss ground and to set incentives so that they would leave the country on their own. But during the implementation, new regulating effects emerged. Drawing on ethnographic material, I will highlight these “messy procedures” (Sciortino 2004). First, I will analyze the means and goals developed by the Federal authorities while conceptualising the termination of social assistance. Second, I will focus on the new built structures and elaborate the practices and legitimating strategies of the authorities. As a conclusion, I will analyze the ambivalences of these processes which, at the end, established specific structures for the “unwanted”.

Effects of Passive Hydrotherapy WATSU (WaterShiatsu) in the Third Trimester of Pregnancy: Results of a Controlled Pilot Study

Background. WATSU (WaterShiatsu) is a complementary therapeutic treatment method comprising passive stretches and massage techniques administered in 35°C warm water. Pregnant women claim safe methods to reduce pain, stress, and fatigue. Therefore, we conducted a pilot study evaluating the effects of WATSU on pregnancy-related complaints in third trimester pregnant women. Methods. Nine healthy pregnant women at gestational week ≥34 were included in an intervention group (receiving WATSU) and compared to eight women in a passive control group (receiving no treatment). WATSU was performed on days 1 and 4 of the study, accompanied by ultrasound examinations. Outcomes include physiological and psychometric as well as qualitative data. Participants in the control group completed questionnaires only. Results. WATSU was found to significantly lower participants’ levels of stress and pain and to improve their mental health-related quality of life and mood. In comparison to the passive control group, participants in the intervention group reported reduction in perceived stress from day 1 to day 8 (p = 0.036, Cohen’s f = 0.57). Qualitative data indicate that WATSU was appreciated as enjoyable and deeply relaxing. No negative side effects were reported. Conclusion. Our findings support the notion that WATSU yields therapeutic benefits for pregnant women and warrant further research. This study has been registered at ClinicalTrials.gov: NCT01708018.

Relaxing hydrotherapy WATSU (WaterShiatsu) and its effects in third trimester of pregnancy

Background WATSU (WaterShiatsu) is a bodywork-technique comprising buoyancy, passive stretches, massage, and acupressure that is administered in 35° C warm water. WATSU is believed to exert beneficial effects on pregnancy-related complaints. We conducted a pilot study to test the hypothesis that WATSU treatment during pregnancy can affect low back pain, everyday stress perception, quality of life, tonus of the uterus, amount of amniotic fluid, spontaneous course of breech presentations, and the success rate of external cephalic versions. Methods Healthy women with singleton pregnancies at gestational week 36 were included in our cohort control pilot trial. Participants in the treatment group (n = 8) received a standardized WATSU-treatment on their first and fourth day of study participation, while participants in the control group were in a waiting condition. Participants underwent ultrasound investigations and completed quantitative and qualitative questionnaires before and after intervention, as well as weekly until birth. Results In contrast to the control group, participants in the WATSU-treatment group reported significant relief of low back pain and stress. After WATSU treatment spontaneous version out of breech position occurred once in seven cases, and external cephalic version was successful in two out of three cases. As qualitative data indicate, WATSU was appreciated as a deep relaxing and enjoyable treatment method. No negative side-effects or adverse events were reported. Conclusion The findings from our pilot-study support the notion that WATSU might yield therapeutic benefits for pregnant women and warrant further research.

Five-Year Outcome of Catheter Ablation of Persistent Atrial Fibrillation Using Termination of Atrial Fibrillation as a Procedural Endpoint.

BACKGROUND -This study aimed to determine five-year efficacy of catheter ablation for persistent atrial fibrillation (PsAF) using AF termination as a procedural endpoint. METHODS AND RESULTS -150 patients (57±10 years) underwent PsAF ablation using a stepwise ablation approach (pulmonary vein isolation, electrogram-guided and linear ablation) with the desired procedural endpoint being AF termination. Repeat ablation was performed for recurrent AF or atrial tachycardia (AT). AF was terminated by ablation in 120 patients (80%). Arrhythmia-free survival rates after a single procedure were 35.3±3.9%, 28.0±3.7%, and 16.8±3.2% at 1, 2, and 5 years, respectively. Arrhythmia-free survival rates after the last procedure (mean 2.1±1.0 procedures) were 89.7±2.5%, 79.8±3.4%, and 62.9±4.5%, at 1, 2, and 5 years, respectively. During a median follow-up of 58 (IQR 43-73) months following the last ablation procedure, 97 of 150 (64.7%) patients remained in sinus rhythm without antiarrhythmic drugs (AADs). Another 14 (9.3%) patients maintained sinus rhythm after re-initiation of AADs, and an additional 15 (10.0%) patients regressed to paroxysmal recurrences only. Failure to terminate AF during the index procedure (HR 3.831; 95%CI: 2.070-7.143; p<0.001), left atrial diameter ≥50mm (HR 2.083; 95%CI: 1.078-4.016; p=0.03), continuous AF duration ≥18 months (HR 1.984; 95%CI: 1.024-3.846; p<0.04) and structural heart disease (HR 1.874; 95% CI: 1.037-3.388; p=0.04) predicted arrhythmia recurrence. CONCLUSIONS -In patients with PsAF, an ablation strategy aiming at AF termination is associated with freedom from arrhythmia recurrence in the majority of patients over a 5-year follow up period.Procedural AF non-termination and specific baseline factors predict long-term outcome after ablation.

Intendedness of pregnancy among active duty women in the U.S. Army

Objective. The objective of this study was to determine the prevalence of unintended pregnancy and the association between social and demographic factors among a population of active duty women in the U.S. Army giving birth to viable infants at a U.S. Army hospital at Fort Hood, Texas. Prevalence of unintended pregnancy in this group was 50.9% (95% CI 44.0 to 57.9) with 36.3% being mistimed (95% CI 29.8 to 33.2) and 14.6% being unwanted (95% CI 10.2 to 20.1). A further 14.2% of the women experienced ambivalence (95% CI 9.8 to 19.6). ^ The study population was a cross-sectional group of active duty pregnant women who represent the target population of all female soldiers that deliver viable infants in the Army. Using a survey based on previous studies, intendedness of pregnancy at conception was retrospectively determined. Unintended births are further characterized as mistimed or unwanted. Demographic and other exposures were described bivariately. Associations were evaluated using measures of relative risk and chi-square analysis. ^ The results of the research indicate that in the study population, race/ethnicity is not associated with unintended pregnancy and non-commissioned officers had a lower rate of unintended pregnancy than other rank groupings. ^
