Current therapy of childhood cancer makes long-term survival a realistic outcome for most patients. However, some treatment regimens entail a significant risk of infertility. No established method for preservation of female fertility is currently available. Ovarian cryopreservation is an experimental technology that is being offered with increasing frequency to women undergoing cancer therapy. It has not yet been reported in children and adolescent girls. The aim of this review is to stimulate discussion on the possibility of performing ovarian cryopreservation in pre-menarcheal girls in advance of therapies that may induce ovarian failure. We present a multi-disciplinary discussion of the risks and benefits associated with the procedure and propose guidelines for its implementation. We propose that all girls about to receive treatment that has a high risk for infertility be offered consultation about the possibility of ovarian cryopreservation. 相似文献
Melatonin is secreted during the night in adults but not in infants. It has a hypnotic effect as well as a relaxing effect
on the smooth muscle of the gastrointestinal tract. It is plausible that breast milk, which consists of melatonin, may have
an effect on improving infants' sleep and reducing infantile colic. Our first goal was to assess the differences in the prevalence
and severity of infantile colic and nocturnal sleep between breast-fed infants and supplement-fed infants. The second was
to characterize the profile of melatonin secretion in human breast milk compared to artificial formulas. Ninety-four mothers
of healthy 2 to 4-month-old infants filled a questionnaire regarding irritability/potential infantile colic and sleep characteristics.
For the second part, we measured melatonin levels in breast milk of five women every 2 h during 24 h and in three samples
of commonly used artificial formulas. Exclusively breast-fed infants had a significantly lower incidence of colic attacks
(p = 0.04), lower severity of irritability attacks (p = 0.03), and a trend for longer nocturnal sleep duration (p = 0.06). Melatonin in human milk showed a clear circadian curve and was unmeasurable in all artificial milks. Conclusions.
Exclusive breastfeeding is associated with reduced irritability/colic and a tendency toward longer nocturnal sleep. Breast
milk (nocturnal) consists of substantial melatonin levels, whereas artificial formulas do not. We speculate that melatonin
which is supplied to the infant via breast milk plays a role in improving sleep and reducing colic in breast-fed infants compared
to formula-fed ones. 相似文献
Research questionIs the interval length between an early pregnancy loss and the following treatment cycle a predictor for achieving clinical pregnancy among IVF patients?DesignThis retrospective cohort study of 257 women who reinitiated treatment after first-trimester IVF pregnancy loss was conducted at a tertiary, university-affiliated medical centre between 1 January 2014 to 1 January 2018. Women aged 18–40 years, with normal uterine cavity, who experienced first-trimester pregnancy loss at less than 14 weeks after IVF, were included. Miscarriages were classified as spontaneous, biochemical, medical or surgical.ResultsAmong 257 women, interval to subsequent IVF treatment was not associated with achieving pregnancy. Patients after biochemical pregnancy (72.7 ± 56.4, median 60 days) or spontaneous miscarriage (97.7 ± 93.1, median 66 days) had shorter intervals to next cycle, compared with medical (111.9 ± 103.2, median 65 days) or surgical (123.4 ± 111.1, median 84 days) (Kaplan–Meier, P = 0.03) miscarriages.Logistic regression analysis showed that the chance of subsequent pregnancy was affected by the number of embryos transferred (P = 0.009) and the type of miscarriage. Medical (P = 0.005) and surgical (P = 0.017) miscarriages were related to lower likelihood of pregnancy compared with biochemical pregnancy (reference group).When pregnancy was achieved in the first post-miscarriage cycle, the chance of live birth increased with shorter intervals (median 57.5 days), whereas second miscarriage was related to longer intervals (median 82.5 days) between miscarriage and subsequent IVF cycle (P = 0.03).ConclusionOn the basis of this cohort, IVF should not be postponed after pregnancy loss, as shorter intervals were associated with greater likelihood of live birth. 相似文献

This work investigates whether inhibition impairments influence the decision making process in pathological gamblers (PGs). The PG (N = 51) subjects performed the Iowa Gambling Task (IGT as the measure of the decision making process) and two tests of inhibition: the Stroop (interference inhibition), and the Go/NoGo (response inhibition), and were compared with demographically matched healthy subjects (N = 57). Performance in the IGT block 1 and block 2 did not differ between the groups, but the differences between the PGs and healthy controls began to be significant in block 3, block 4 and block 5. PGs learned the IGT task more slowly than the healthy controls and had non-optimal outcomes (more disadvantageous choices). Impaired IGT performance in PGs was not related to an inhibition ability measured by the Stroop (interference response time) and the Go/NoGo (number of commission errors) parameters. Further controlled studies with neuroimaging techniques may help to clarify the particular brain mechanisms underlying the impaired decision making process in PGs. 相似文献
AbstractPurpose: To determine if head circumference (HC) is an independent factor influencing second stage duration stratified by parity and epidural use.Materials and methods: A retrospective cohort analysis of all live, singleton, term (37–42 weeks) vaginal deliveries in one university affiliated medical center (2012–2014). Exclusion criteria included operative deliveries due to fetal distress, major fetal anomalies/chromosomal abnormalities or cases with missing anthropometric data. Maternal demographics, labor characteristics and neonatal anthropometrics including birth weight and HC were retrieved. Multivariate linear regression was utilized to evaluate the association between HC and second stage duration. Analysis was stratified into four groups by parity and epidural use.Results: Of the 16 240 singleton vaginal deliveries during study period, 12 428 deliveries met inclusion criteria. Stratification by parity and epidural analgesia yielded four groups: 3337 (26.9%), 735 (5.9%), 5099 (41.0%) and 3257 (26.2%) deliveries – nullipara with/without epidural and multipara with/without epidural, respectively. In all groups, a large neonatal HC was significantly and independently associated with longer second stage duration: nullipara with epidural (beta 10.06, 95% CI 7.75–12.37), nullipara without epidural (beta 7.58, 95% CI 4.73–10.43), multipara with epidural (beta 4.64, 95%CI 3.47–5.8) and multipara without epidural (beta 1.35, 95% CI 0.76–1.94), p?<?.001 for all. Birth weight was not associated with second stage duration in any of the groups (p?>?.05).Conclusion: Large neonatal HC is significantly associated with longer second stage duration. 相似文献
This study examined the relationship between suicidality and dependent and self-critical depression among adolescents. Ninety-six adolescents participated: 32 suicidal inpatients, 32 nonsuicidal inpatients and 32 healthy controls. The groups were matched for gender, age and education. Participants completed the Depressive Experience Questionnaire for Adolescents (DEQ-A), the Cognition Checklist (CCL), and the Multi-Attitude Suicidal Tendencies Scale (MAST). Results indicated that suicidal adolescents have significantly higher levels of self-critical and dependent depression, compared to nonsuicidal inpatients and healthy controls. The distinctive quality of depression among suicidal adolescents suggests assessment and treatment strategies for these individuals. 相似文献
This study examined the relationship between stressful life events (SLE) and recurrent major depressive disorders. Three groups of 50 subjects were assessed: Patients with recurrent major depressive disorder with melancholic features; patients with borderline personality disorder; and healthy controls. Interviews for AXIS I and II DSM-IV Disorders were used for diagnosis. The Israel Psychiatric Epidemiology Research Interview Life Event Scale and the Coddington Life Events Schedule were used to measure life events and were confirmed with an interview. Beck Depression Inventory was also administered. The proportions of loss-related events in childhood and in the year preceding the first episode were higher in the depressed group than in the control groups during the same time period. Proportions of SLE, uncontrolled and independent events were also more common in the depressed patients in the year preceding the first episode. No category of SLE differentiated the groups following the first depressive episode. The study's conclusion is that SLE play an important role in the onset of depressive disorders. There are specific kinds of SLE that occur in childhood and in the year preceding the first episode. SLE has a less significant role in the maintenance of this illness. 相似文献
Background: A tri-modal distribution of age-at-onset emerged among females patients with myasthenia gravis (MG) in our database. This finding may be indicative of different gender-based disease mechanisms.
Methods: We retrospectively reviewed the files of 127?MG patients for the clinical, serology and thymus pathology according to their age at disease onset: ≤40 years (early-onset, EOMG), 40–70 years (intermediate-onset, IOMG) and >70 years (late-onset, LOMG).
Results: EOMG was more common among females, and IOMG was more common among males. Ocular MG was more common among the male MG patients with an IOMG. Patients with EOMG had lower rates of positive anti-acetylcholine receptor (anti-AChR). IOMG females, but not IOMG males, had lower rates of positive anti-AChR. IOMG and EOMG females had high rates of thymic hyperplasia, while EOMG males had high rates of thymoma. Comorbidity with autoimmune diseases was common among females with IOMG and LOMG.
Conclusions: The prevalence of IOMG was the reason for the trend reversal of MG prevalence between genders. The clinical features of patients with IOMG differed between genders in the rates of positive anti-AChR, follicular hyperplasia of the thymus and comorbidity with autoimmune diseases. This may suggest a different gender-based mechanism of immune intolerance towards AChR and other antigens. 相似文献
