Abstract
Background. Brain lesions may disturb binocular fusion and stereopsis, leading to blurred vision, diplopia, and reduced binocular depth perception for which no evaluated treatment is currently available. Objective. The study evaluated the effects of a novel binocular vision treatment designed to improve convergent fusional amplitude and stereoacuity in patients with stroke or traumatic brain injury (TBI). Methods. Patients (20 in all: 11 with stroke, 9 with TBI) were tested in fusional convergence, stereoacuity, near/far visual acuity, accommodation, and subjective binocular reading time until diplopia emerged at 6 different time points. All participants were treated in a single subject baseline design, with 3 baseline assessments before treatment (pretherapy), an assessment immediately after a 6-week treatment period (posttherapy), and 2 follow-up tests 3 and 6 months after treatment. Patients received a novel fusion and dichoptic training using 3 different devices to slowly increase fusional and disparity angles. Results. At pretherapy, the stroke and TBI groups showed severe impairments in convergent fusional range, stereoacuity, subjective reading duration, and partially in accommodation (only TBI group). After treatment, both groups showed considerable improvements in all these variables as well as slightly increased near visual acuity. No significant changes were observed during the pretherapy and follow-up periods, ruling out spontaneous recovery and demonstrating long-term stability of binocular treatment effects. Conclusions. This proof-of-principle study indicates a substantial treatment-induced plasticity of the lesioned brain in the relearning of binocular fusion and stereovision, thus providing new, effective rehabilitation strategies to treat binocular vision deficits resulting from permanent visual cortical damage.

Abstract
Position sense is an important proprioceptive ability. Disorders of arm position sense (APS) often occur after unilateral stroke, and are associated with a negative functional outcome. In the present study we assessed horizontal APS by measuring angular deviations from a visually defined target separately for each arm in a large group of healthy subjects. We analyzed the accuracy and instability of horizontal APS as a function of age, sex and arm. Subjects were required to specify verbally the position of their unseen arm on a 0-90° circuit by comparing the current position with the target position indicated by a LED lamp, while the arm was passively moved by the examiner. Eighty-seven healthy subjects participated in the study, ranging from 20 to 77 years, subdivided into three age groups. The results revealed that APS was not a function of age or sex, but was significantly better in the non-dominant (left) arm in absolute errors (AE) but not in constant errors (CE) across all age groups of right-handed healthy subjects. This indicates a right-hemisphere superiority for left APS in right-handers and neatly fits to the more frequent and more severe left-sided body-related deficits in patients with unilateral stroke (i.e. impaired APS in left spatial neglect, somatoparaphrenia) or in individuals with abnormalities of the right cerebral hemisphere. These clinical issues will be discussed.

Abstract
Tactile extinction is frequent, debilitating, and often persistent after brain damage. Currently, there is no treatment available for this disorder. In two previous case studies we showed an influence of galvanic vestibular stimulation (GVS) on tactile extinction. Here, we evaluated in further patients the immediate and lasting effects of GVS on tactile extinction. GVS is known to induce polarity-specific changes in cerebral excitability in the vestibular cortices and adjacent cortical areas. Tactile extinction was examined with the Quality Extinction Test (QET) where subjects have to discriminate six different tactile fabrics in bilateral, double simultaneous stimulations on their dorsum of hands with identical or different tactile fabrics. Twelve patients with stable left-sided tactile extinction after unilateral right-hemisphere lesions were divided into two groups. The GVS group (N = 6) performed the QET under six different experimental conditions (two Baselines, Sham-GVS, left-cathodal/right-anodal GVS, right-cathodal/left-anodal GVS, and a Follow-up test). The second group of patients with left-sided extinction (N = 6) performed the QET six times repetitively, but without receiving GVS (control group). Both right-cathodal/left-anodal as well as left-cathodal/right-anodal GVS (mean: 0.7 mA) improved tactile identification of identical and different stimuli in the experimental group. These results show a generic effect of GVS on tactile extinction, but not in a polarity-specific way. These observed effects persisted at follow-up. Sham-GVS had no significant effect on extinction. In the control group, no significant improvements were seen in the QET after the six measurements of the QET, thus ruling out test repetition effects. In conclusion, GVS improved bodily awareness permanently for the contralesional body side in patients with tactile extinction and thus offers a novel treatment option for these patients.

Abstract
Background. Disturbed arm position sense (APS) is a frequent and debilitating condition in patients with hemiparesis after stroke. Patients with neglect, in particular, show a significantly impaired contralesional APS. Currently, there is no treatment available for this disorder. Galvanic vestibular stimulation (GVS) may ameliorate neglect and extinction by activating the thalamocortical network. Objective. The present study aimed to investigate the immediate effects and aftereffects (AEs; 20 minutes) of subsensory, bipolar GVS ( M = 0.6 mA current intensity) on APS in stroke patients with versus without spatial neglect and matched healthy controls. Methods. A novel optoelectronic arm position device was developed, enabling the precise measurement of the horizontal APS of both arms. In all, 10 healthy controls, 7 patients with left-sided hemiparesis and left-spatial neglect, and 15 patients with left hemiparesis but without neglect were tested. Horizontal APS was measured separately for both forearms under 4 experimental conditions (baseline without GVS, left-cathodal/right-anodal GVS, right-cathodal/left-anodal GVS, sham GVS). The immediate effects during GVS and the AEs 20 minutes after termination of GVS were examined. Results. Patients with neglect showed an impaired contralateral APS in contrast to patients without neglect and healthy controls. Left-cathodal/right-anodal GVS improved left APS significantly, which further improved into the normal range 20 minutes poststimulation. GVS had no effect in patients without neglect but right-cathodal/left-anodal GVS worsened left APS in healthy participants significantly. Conclusions. GVS can significantly improve the impaired APS in neglect. Multisession GVS can be tested to induce enduring therapeutic effects.

Abstract
STUDY QUESTION Does prior depression in women treated with assisted reproduction technology (ART) influence the number of treatment cycles and ART live births? SUMMARY ANSWER Women with a depression diagnosis prior to ART treatment initiated statistically significantly fewer ART treatment cycles and had a lower mean number of ART live births compared with women with no history of depression. WHAT IS KNOWN ALREADY Previous studies have shown an increased prevalence of depressive symptoms in fertility patients than in the comparison groups. STUDY DESIGN, SIZE, DURATION A register-based national cohort study, including all women (n = 42,915) treated with IVF, ICSI, frozen embryo transfer and oocyte recipient cycle in Denmark from 1 January 1994 to 30 September 2009 extracted from the IVF register (ART cohort). Data on births and depression diagnoses were obtained by linking to the Danish Medical Birth Register (1994-2010) and the Danish Psychiatric Central Research Register (1969-2010). PARTICIPANTS/MATERIALS, SETTING, METHODS For each woman in the ART cohort, we included five age-matched women from the female background population not having received ART treatment. This comparison group was cross-linked with identical register data as the ART cohort. Women with incomplete ART information or a depression diagnosis before 18 years of age were excluded; remaining n = 42,880. The ART cohort was grouped into (i) women with a depression diagnosis and (ii) women never diagnosed with depression. In the ART group with depression, analyses were specified on women with their first depression prior to ART treatment. In total, 2.6% of the women in the ART cohort had a depression diagnosis. For the incidence rate ratio (IRR) 39,194 women from the ART cohort (3686 women were excluded due to migration) were compared with 206,005 women from the age-matched comparison group who did not receive ART treatment. MAIN RESULTS AND THE ROLE OF CHANCE Of the women in the ART cohort with a depression diagnosis, 34.7% had their first depression diagnosis prior to ART treatment, 4.7% during ART treatment and 60.7% after ART treatment. The mean number of initiated ART cycles was significantly lower in the ART group of women having a depression diagnosis prior to ART treatment [2.55 (±1.78)] compared with the ART group of women without a depression diagnosis [3.22 (±2.31); P < 0.001; P < 0.001]. Women having a depression diagnosis prior to ART treatment had a lower mean number of ART live births [0.82 (±0.73)] compared with women without a depression diagnosis [1.03 (±0.81); P < 0.001]. The incidence rate of first and recurrent depression diagnoses in the ART cohort was significantly lower compared with the age-matched background population group; IRR = 0.80 (P < 0.001) and IRR = 0.77 (P < 0.001). LIMITATIONS, REASONS FOR CAUTION Only clinical depression diagnoses treated in a psychiatric hospital setting are included. The age-matched comparison group from the background population is heterogeneous as it consists of women differing in fertility status (both mothers and childless women). WIDER IMPLICATIONS OF THE FINDINGS Fewer women in the ART cohort developed depression over time compared with the age-matched background population, which might reflect a healthy patient effect of the women seeking ART treatment. Women with a depression diagnosis before ART treatment receive fewer ART treatments and are less likely to achieve an ART live birth. These women might be more vulnerable and we recommend that they be offered more psychiatric attention before starting, as well as during and after ART treatment.

Abstract
Many neglect patients show deficits in the mental representation of their contralesional body side or body parts, termed personal neglect. These deficits include impairments in identifying body parts on schematic drawings of human bodies. Limb activation and alertness cues have been shown to modulate neglect transiently, and are effective treatments for several symptoms of the neglect syndrome. Here, we tested on eight patients with right-hemispheric stroke and left-sided spatial neglect whether these two techniques modulate deficits in the mental representation of hands, assessed with a hand-test in which the subjects had to decide whether a depicted schematic hand belongs to the left or right side of the human body. The results showed that neglect patients made marginally significant (p = 0.065) more errors in left-hand-decisions than right-hand-decisions, indicating a neglect-specific disorder. Moreover, we found that left-sided limb activation but not non-lateralized alertness cueing (a loud noise immediately before patients made their perceptual decision) significantly reduced misidentifications for depicted left hands as compared to baseline. No effect of any intervention was observed on error rates for depicted right hands. We conclude that the amelioration of the performance in the hand task is modulated by the activation of the body schema or other body representations through left-sided limb activation.

Abstract
BACKGROUND Across the developed world couples are postponing parenthood. This review assesses the consequences of delayed family formation from a demographic and medical perspective. One main focus is on the quantitative importance of pregnancy postponement. METHODS Medical and social science databases were searched for publications on relevant subjects such as delayed parenthood, female and male age, fertility, infertility, time to pregnancy (TTP), fetal death, outcome of medically assisted reproduction (MAR) and mental well-being. RESULTS Postponement of parenthood is linked to a higher rate of involuntary childlessness and smaller families than desired due to increased infertility and fetal death with higher female and male age. For women, the increased risk of prolonged TTP, infertility, spontaneous abortions, ectopic pregnancies and trisomy 21 starts at around 30 years of age with a more pronounced effects >35 years, whereas the increasing risk of preterm births and stillbirths starts at around 35 years with a more pronounced effect >40 years. Advanced male age has an important but less pronounced effect on infertility and adverse outcomes. MAR treatment cannot overcome the age-related decline in fecundity. CONCLUSIONS In general, women have partners who are several years older than themselves and it is important to focus more on the combined effect of higher female and male age on infertility and reproductive outcome. Increasing public awareness of the impact of advanced female and male age on the reproductive outcome is essential for people to make well-informed decisions on when to start family formation.

Abstract
AIMS Maternal diabetes may affect offspring cognitive function. The objective of the study was to evaluate cognitive function and potential predictors hereof in adult offspring of women with Type 1 diabetes. METHODS We conducted a follow-up study of adult offspring of women with Type 1 diabetes (n = 158) and a reference group from the background population (n = 118). The main outcome measure was offspring cognitive function measured by global cognitive score, derived from Raven's Progressive Matrices and three verbal subtests from the Weschler Adult Intelligence Scale. RESULTS Offspring of women with Type 1 diabetes obtained lower global cognitive scores (94.8 vs. 100.0, P = 0.004) than offspring from the background population. When adjusted for confounders, the groups no longer differed significantly (difference 0.4, 95% CI -3.3 to 4.). Positive predictors of cognitive function in offspring of women with diabetes were family social class, parental educational level, maternal diabetes duration, male gender and offspring age, whereas parity ≥ 1 and gestational age < 34 weeks were negative predictors. We found no association with maternal glycaemia during pregnancy or with neonatal hypoglycaemia. CONCLUSIONS Impaired cognitive function in adult offspring of women with Type 1 diabetes compared with the background population apparently reflects differences with respect to well-known confounders. However, harmful effects of maternal hyperglycaemia may be mediated through delivery at < 34 weeks.

Abstract
HISTORY AND ADMISSION FINDINGS One month after a first manifestation of a hepatitis A infection and transaminases had become normal, a 44-year-old woman again became jaundiced with accompanied by weakness, nausea and nocturnal sweating. INVESTIGATIONS Laboratory tests again showed features of hepatitis with decreased synthetic liver function and hyperbilirubinemia, changes which persisted for 12 weeks. Serological and virological studies revealed a positive test for anti-hepatitis A virus (HAV) IgM and HAV-RNA was detected in the stool. DIAGNOSIS, TREATMENT AND COURSE These tests demonstrated two rare features of hepatitis A, namely a prolonged biphasic course combined with cholestasis form. In addition a hemolytic anaemia developed. CONCLUSION The severity of a relapse of hepatitis A varies: in this case it was more severe than the initial manifestation. The reasons for the different courses of hepatitis A infection remain unclear.
