    “Advice and Consent” in Historical Perspective

    In recent years, commentators have complained about what they regard as an increasingly dysfunctional confirmation process for judges and high-ranking executive officials, and the proper role for the Senate in the confirmation process has been much debated. This Article suggests that confirmations have been contentious throughout American history, and that the focus on ideological issues in today’s confirmation proceedings is not anomalous. Indeed, historically, both Republicans and Democrats have used the confirmation process to delay or oppose nominations when the President hails from a different political party, and, sometimes, even when the President comes from the same party but there are ideological objections to the nominee. That the appointments process has, at times, been difficult and contentious should come as no great surprise. The Framers of the United States Constitution intentionally created a governmental structure that was more prone to obstructionism than other comparable systems. Relying on concepts like “separation of powers,” and “checks and balances,” the Framers sought to constrain the federal government in ways that would limit the possibilities for governmental abuse. The appointments power reflects this approach. Like many other constitutional powers, it is a shared power. Although the President has the power to nominate Article III judges, as well as ambassadors and “officers,” nominees can only be confirmed with the “advice and consent” of the Senate. By placing the power to appoint in two politically elected entities, the Constitution establishes a system whereby political influences will sometimes have a major impact on the confirmation process. Although contentiousness can arise during any type of nomination, some Supreme Court nominations have been particularly bitter. Both the Senate and the American public have increasingly become aware that the courts make law and that the political and judicial attitudes of nominees matter. Under such circumstances, the Senate’s inquiry quite naturally goes beyond the simple question of whether a nominee is qualified or unqualified. However, the confirmation process is more difficult today, even for nonjudicial nominees, because of the bitter partisanship that has infected the U.S. political system

    BACKGROUND: the objective of this study is to investigate the detection rate of undiagnosed atrial fibrillation (AF) with short intermittent ECG recordings during four weeks among out-of-hospital patients, having at least one additional risk factor (CHADS(2)) for stroke. METHOD: Design: Cross-sectional study. Setting: Eight family practice centres and two hospital-based out-patient clinics in Sweden. Subjects: 989 out-of-hospital patients, without known AF, having one or more risk factors associated with stroke (CHADS(2)). Interventions: All individuals were asked to perform 10-second handheld ECG recordings during 28 days, twice daily and when having palpitations. Main outcome measures: Episodes of AF on handheld ECG recordings were defined as irregular supraventricular extrasystoles in series with a duration of 10 seconds. RESULTS: 928 patients completed registration. AF was found in 35 of 928 patients; 3.8% (95% confidence interval [CI] 2.7–5.2). These 35 patients had a mean age of 70.7 years (SD ± 7.7; range 53–85) and a median CHADS(2) of 2 (range 1–4). CONCLUSIONS: Intermittent handheld ECG recording over a four week period had a detection rate of 3.8% newly diagnosed AF, in a population of 928 out-of-hospital patients having at least one additional risk factor for stroke. Intermittent handheld ECG registration is a feasible method to detect AF in patients with an increased risk of stroke in whom oral anticoagulation (OAC) treatment is indicated

    Low vitamin D levels during pregnancy may have negative consequences for the health of both the mother and child. Cross-sectional studies in childbearing women suggest that vitamin D levels are low during pregnancy, but few studies have followed the same women during pregnancy and postpartum. The aims of this study were to longitudinally assess vitamin D status during pregnancy and postpartum and identify the factors associated with vitamin D status in pregnant women in northern Sweden. Between September 2006 and March 2009, 184 women were consecutively recruited at five antenatal primary care clinics. Blood was sampled, and dietary intake was estimated using a food frequency questionnaire with 66 food items/food aggregates and questions on the intake of vitamin supplements at gestational weeks 12, 21, and 35, as well as at 12 and 29 weeks after birth. Plasma 25(OH) vitamin D levels were analyzed using liquid chromatography tandem-mass spectrometry. At least one-third of the women had 25(OH) vitamin D levels <50 nmol/L on at least one sampling occasion. Plasma levels increased slightly over the gestation period and peaked in late pregnancy. The levels reverted to the baseline levels after birth. Multivariate analysis showed that gestational and postpartum week, season, dietary intake of vitamin D, and vitamin supplementation were significantly related to plasma levels. There was also an influence of season on the longitudinal concentration patterns. In conclusion, more than one-third of the women studied had low 25(OH) vitamin D levels, and gestational and postpartum week was related to 25(OH) vitamin D levels after adjustment for season and vitamin D intake

    Remote evaluation of video-otoscopy recordings in an unselected pediatric population with an otitis media scale

    BACKGROUND : A recently validated image-based grading scale for acute otitis media (OMGRADE) can be used to assess tympanic membrane (TM) status. The aim of this study was to evaluate the validity and reliability of this scale for remote assessments of TM status using video-otoscopy recordings in an unselected pediatric population. METHOD : Children 2–16 years attending a South African primary health clinic were offered an ear examination by an otologist using otomicroscopy. An ear and hearing telehealth facilitator then made video-otoscopy recordings (9–33 s) of the ears and uptakes were uploaded to a secure server for remote assessments in Sweden by an otologist and general practitioner at four- and eight-weeks post onsite assessment. TM appearance was judged according to the OMGRADE scale. Concordance between onsite otomicroscopy and asynchronous assessments of video-otoscopy recordings was calculated together with intra- and inter-rater agreements. RESULTS : One hundred and eighty ears were included. Concordance of TM classifications using the OMGRADE scale was found to be substantial (weighted kappa range 0.66–0.79). Intra- and inter-rater agreement (test–retest) was found to be substantial to almost perfect (weighted kappa range 0.85–0.88 and 0.69–0.72, respectively). CONCLUSION : The OMGRADE scale can be used to accurately assess the normal TM and secretory otitis media (SOM) remotely using video-otoscopy recordings in an unselected pediatric population.http://www.elsevier.com/locate/ijporlhb201

    Deuterium-carbon multiple-quantum NMR in liquid crystals: polarization transfer and off-magic-angle spinning

    No full text
    The polarization transfer dynamics in a recently introduced deuterium-carbon NMR correlation method is studied, both theoretically and experimentally. The technique, which exploits heteronuclear multiple-quantum coherences, is useful for measuring and assigning 2H quadrupolar couplings in ordered media. It is also shown that the experiment is suitable for implementation under off-magic-angle spinning conditions. The approach is demonstrated on a perdeuterated liquid crystal

    The relationship between weight gain during pregnancy and allopregnanolone levels : a longitudinal study

    Objective: Large weight gain during pregnancy is a risk factor for complications for mother and fetus. Hunger and satiety are regulated in the hypothalamus, where the gamma-amino-butyric acid system (GABA) has an important role. Allopregnanolone, a progesterone metabolite, increases during pregnancy and is a potent GABA-A receptor modulating steroid. Allopregnanolone has been shown to induce overeating in rodents. The aim was to investigate whether there is a relationship between weight gain and allopregnanolone concentrations during pregnancy in humans. Design: A longitudinal, cohort study. Methods: Pregnant women (n = 56) were recruited in primary care in northern Sweden. Allopregnanolone concentrations in plasma were measured using radioimmunoassay and weight was measured in gestational weeks 12 and 35. Results: Weight increase correlated significantly to allopregnanolone in late pregnancy increase (r(s) = 0.320; P = 0.016), indicating a positive relationship between weight increase and allopregnanolone increase. A positive relationship was also noted between allopregnanolone in the 35th gestational week and weight increase. Women who gained = 11 kg during pregnancy showed higher allopregnanolone concentrations in week 35 and higher increase compared to women who increased < 11 kg (P = 0.006 and P = 0.009 resp.). There was no difference in weight or allopregnanolone concentrations at the onset of pregnancy. Conclusions: The results show a relationship between weight gain during pregnancy and increase in allopregnanolone concentrations

    Heteronuclear dipolar recoupling in liquid crystals and solids by PISEMA-type pulse sequences

    No full text
    A pulse sequence is described for the recoupling of heteronuclear dipolar interactions under MAS. The method is similar to the PISEMA experiment, but employs a well-defined amplitude modulation of one of the two radio-frequency fields. The technique is used for measurements of 1H–13C dipolar couplings in unoriented solid and liquid-crystalline samples
