Effects and Clinical Significance of GII.4 Sydney Norovirus,United States, 2012–2013

During 2012, global detection of a new norovirus (NoV) strain, GII.4 Sydney, raised concerns about its potential effect in the United States. We analyzed data from NoV outbreaks in 5 states and emergency department visits for gastrointestinal illness in 1 state during the 2012–13 season and compared the data with those of previous seasons. During August 2012–April 2013, a total of 637 NoV outbreaks were reported compared with 536 and 432 in 2011–2012 and 2010–2011 during the same period. The proportion of outbreaks attributed to GII.4 Sydney increased from 8% in September 2012 to 82% in March 2013. The increase in emergency department visits for gastrointestinal illness during the 2012–13 season was similar to that of previous seasons. GII.4 Sydney has become the predominant US NoV outbreak strain during the 2012–13 season, but its emergence did not cause outbreak activity to substantially increase from that of previous seasons.     

Mediastinal lymphadenopathy and pulmonary arterial hypertension in mixed connective tissue disease

A case of mixed connective tissue disease (MCTD) is presented in which mediastinal lymphadenopathy was the most prominent radiological finding detected by plain chest radiographs and computed tomography. Pulmonary arterial hypertension, which is a rare and often fatal complication of MCTD, also developed in this patient.     

Mental Health Diagnoses 3 Years After Receiving or Being Denied an Abortion in the United States

Objectives. We set out to assess the occurrence of new depression and anxiety diagnoses in women 3 years after they sought an abortion.Methods. We conducted semiannual telephone interviews of 956 women who sought abortions from 30 US facilities. Adjusted multivariable discrete-time logistic survival models examined whether the study group (women who obtained abortions just under a facility’s gestational age limit, who were denied abortions and carried to term, who were denied abortions and did not carry to term, and who received first-trimester abortions) predicted depression or anxiety onset during seven 6-month time intervals.Results. The 3-year cumulative probability of professionally diagnosed depression was 9% to 14%; for anxiety it was 10% to 15%, with no study group differences. Women in the first-trimester group and women denied abortions who did not give birth had greater odds of new self-diagnosed anxiety than did women who obtained abortions just under facility gestational limits.Conclusions. Among women seeking abortions near facility gestational limits, those who obtained abortions were at no greater mental health risk than were women who carried an unwanted pregnancy to term.There has been much interest in understanding the effects of abortion, one of the most commonly performed surgical procedures,1,2 on women’s mental health outcomes. Leading reviews on this topic have found no evidence of mental health harm from an abortion,3–6 with the exception of 1 review7 which has been critically refuted.5,8–11 These reviews have called for more research of women seeking abortion beyond the first trimester, longitudinal studies, studies that control for preexisting mental health conditions, and studies that compare women who have had an abortion to women who want an abortion but are unable to get one.3–5Most of the few longitudinal studies available have been conducted outside of the United States. A Danish population-based cohort study assessed the onset of a first psychiatric event before and up to 12 months after a first-trimester abortion and found no increased risk of mental disorders after abortion.12 A Norwegian study followed 120 women for 5 years and compared the psychological response of women who had first-trimester abortions to women who had miscarriages,13 finding no differences in depression or anxiety between the 2 groups.13 Fergusson et al. published a series of articles based on a longitudinal study conducted in New Zealand that suggested that abortion is associated with an increased risk of mental health problems.14,15 These studies, however, have a number of shortcomings that have been discussed elsewhere and may not be generalizable to the US setting.4 One of the few longitudinal US studies is a secondary analysis of the National Comorbidity Survey that compared the mental health outcomes of women who obtained abortions to women who gave birth.16 In this study, the predictive effect of abortion on mental health conditions disappeared when analyses controlled for mental health history.16In this article, we report on the first 3 years of a 5-year longitudinal study, the Turnaway Study, which was specifically designed to examine the psychological consequences of undergoing or being denied an abortion in the United States. Previous findings from the Turnaway Study have demonstrated that most women seeking abortions for financial-, timing-, or partner-related reasons17 commonly express feelings of relief after the abortion and feel that abortion was the right decision.18 The mental health symptom trajectories of women who sought an abortion differed little from those who were denied one; however, both improved over time.19 Our previous analysis19 assessed self-reported mental health symptoms at 5 discrete points in time over 2 years (potentially missing symptoms of anxiety and depression that may have occurred in between interview dates or after 2 years), and it did not assess women’s severity of symptoms or other circumstances that may have led to a clinical diagnosis of depression or anxiety. This study further contributes to the literature by assessing diagnoses of new depression and anxiety disorders that may have occurred in women at any point up to 3 years after having sought an abortion.     

A survey of case studies on the use of forensic three-dimensional printing in England and Wales

3D printing has rapidly developed and been applied in forensic science due to its use in creating demonstrations for courts of law. Much of the literature on this specific topic has focused on the use of 3D printed models in academia, the potential influence on a jury, and its use as a long-term documentation process, but with few actual forensic case examples. This paper offers an insight into the development of 3D printing in forensic practice and how 3D printing is currently being used in the criminal justice system in England and Wales.

A series of case reports were gathered from multiple police forces and forensic practitioners in the UK to identify how 3D printing was being used. These discussions established who was requesting 3D printed exhibits, what type of technologies were being utilised, what type of exhibits were being printed, and resulting feedback for the use of 3D printed material within a criminal case. As a result, this research demonstrates the current use of 3D printing in England and Wales, discussing the associated cases that have been known to incorporate 3D prints. Likewise, this work explores the limitations that have been encountered by forensic practitioners and identifies a series of research questions that should be considered in future investigations.

     

Retrograde Inversion Stripping as a Complication of the Clarivein? Mechanochemical Venous Ablation Procedure

The endovenous revolution has accelerated the development of new techniques and devices for the treatment of varicose veins. The ClariVein^® mechanochemical ablation device offers tumescentless treatment with a rotating ablation tip that can theoretically become stuck in tissue. We present the first report of retrograde stripping of the small saphenous vein without anaesthesia following attempted use of the ClariVein^® device, without adverse sequelae.     

A study of antihaemophilic globulin (factor VIII) consumption.

A study has been made of the rate of disappearance of factor VIII during the clotting of normal plasma samples and of samples deficient in factors V, VII, IX, X, XI and XII. The rate of disappearance (or consumption) of factor VIII was the same in the normal and factor VII deficient samples. Delayed disappearance of factor VIII was observed in samples deficient in factors V, IX, X, XI and XII. The significance of the findings to the theory of blood coagulation is discussed.     

Urine Collagen Fragments and CKD Progression—The Cardiovascular Health Study

Tubulointerstitial fibrosis is common with ageing and strongly prognostic for ESRD but is poorly captured by eGFR or urine albumin to creatinine ratio (ACR). Higher urine levels of procollagen type III N-terminal propeptide (PIIINP) mark the severity of tubulointerstitial fibrosis in biopsy studies, but the association of urine PIIINP with CKD progression is unknown. Among community-living persons aged ≥65 years, we measured PIIINP in spot urine specimens from the 1996 to 1997 Cardiovascular Health Study visit among individuals with CKD progression (30% decline in eGFR over 9 years, n=192) or incident ESRD (n=54) during follow-up, and in 958 randomly selected participants. We evaluated associations of urine PIIINP with CKD progression and incident ESRD. Associations of urine PIIINP with cardiovascular disease, heart failure, and death were evaluated as secondary end points. At baseline, mean age (±SD) was 78±5 years, mean eGFR was 63±18 ml/min per 1.73 m², and median urine PIIINP was 2.6 (interquartile range, 1.4–4.2) μg/L. In a case-control study (192 participants, 231 controls), each doubling of urine PIIINP associated with 22% higher odds of CKD progression (adjusted odds ratio, 1.22; 95% confidence interval, 1.00 to 1.49). Higher urine PIIINP level was also associated with incident ESRD, but results were not significant in fully adjusted models. In a prospective study among the 958 randomly selected participants, higher urine PIIINP was significantly associated with death, but not with incident cardiovascular disease or heart failure. These data suggest higher urine PIIINP levels associate with CKD progression independently of eGFR and ACR in older individuals.
