Discussing reproductive health in spinal care, part II: fertility issues

Abstract PURPOSE: Due to advancing insights, discussing fertility in spinal care is an emerging topic. Studies among neurosurgeons to evaluate clinical practice about discussing fertility are non-existent. The aim of this study is to review knowledge, attitude and practice patterns regarding discussing fertility in spinal care. METHODS: Dutch neurosurgeons and residents were sent a mail-based questionnaire addressing attitude, knowledge and practice patterns regarding discussing fertility. RESULTS: Response rate was 62 % (compared to mean of 28 % in similar surveys) with 89 questionnaires suitable for analysis. Mean age was 42 years with 83 % of respondents being male. A quarter of respondents stated neurosurgeons are responsible to discuss fertility, with 12 % indicating to actually do this. Fertility is discussed more often with patients with cauda equina syndrome (70 %) and with men (p = 0.006). Merely 8 % of respondents stated to have adequate knowledge on fertility preservation (FP); this percentage was higher for doctors with spinal surgery as specialty (p = 0.015). In case of cauda equina syndrome, doctors with more knowledge discussed fertility more often (p = 0.002). Fifty-three percent of neurosurgeons wished to enhance their knowledge, in order to feel more comfortable to discuss fertility with their patients. Five percent indicated to have ever referred a patient to a fertility specialist. CONCLUSION: With the exception of cauda equina syndrome, fertility is not routinely discussed in spinal care. Fertility is discussed more often with men. Recent guidelines state that discussing fertility is an essential part of good practice in spinal care. Education on fertility and FP needs to be integrated in the neurosurgical training program to create more awareness, and to enable clinicians to provide adequate information and care to the patient.

Determinants of maternal pregnancy one-carbon metabolism and newborn human DNA methylation profiles

Maternal one-carbon (1-C) metabolism provides methylgroups for fetal development and programing by DNA methylation as one of the underlying epigenetic mechanisms. We aimed to investigate maternal 1-C biomarkers, folic acid supplement use, and MTHFR C677T genotype as determinants of 1-C metabolism in early pregnancy in association with newborn DNA methylation levels of fetal growth and neurodevelopment candidate genes. The participants were 463 mother-child pairs of Dutch national origin from a large populationbased birth cohort in Rotterdam, The Netherlands. In early pregnancy (median 13.0 weeks, 90% range 10.4-17.1), we assessed the maternal folate and homocysteine blood concentrations, folic acid supplement use, and the MTHFR C677T genotype in mothers and newborns. In newborns, DNA methylation was measured in umbilical cord blood white blood cells at 11 regions of the seven genes: NR3C1, DRD4, 5-HTT, IGF2DMR, H19, KCNQ1OT1, and MTHFR. The associations between the 1-C determinants and DNA methylation were examined using linear mixed models. An association was observed between maternal folate deficiency and lower newborn DNA methylation, which attenuated after adjustment for potential confounders. The maternal MTHFR TT genotype was significantly associated with lower DNA methylation. However, maternal homocysteine and folate concentrations, folic acid supplement use, and the MTHFR genotype in the newborn were not associated with newborn DNA methylation. The maternal MTHFR C677T genotype, as a determinant of folate status and 1-C metabolism, is associated with variations in the epigenome of a selection of genes in newborns. Research on the implications of these variations in methylation on gene expression and health is recommended

DNA methylation profiles at birth and child ADHD symptoms

Attention deficit/hyperactivity disorder (ADHD) is a common and highly heritable psychiatric disorder. In addition, early life environmental factors contribute to the occurrence of ADHD. Recently, DNA methylation has emerged as a mechanism potentially mediating genetic and environmental effects.Here, we investigated whether newborn DNA methylation patterns of selected candidate genes involved in psychiatric disorders or fetal growth are associated with ADHD symptoms in childhood. Participants were 426 children from a large population based cohort of Dutch national origin. Behavio

Using behavior-analytic implicit tests to assess sexual interests among normal and sex-offender populations

The development of implicit tests for measuring biases and behavioral predispositions is a recent development within psychology. While such tests are usually researched within a social-cognitive paradigm, behavioral researchers have also begun to view these tests as potential tests of conditioning histories, including in the sexual domain. The objective of this paper is to illustrate the utility of a behavioral approach to implicit testing and means by which implicit tests can be built to the standards of behavioral psychologists. Research findings illustrating the short history of implicit testing within the experimental analysis of behavior are reviewed. Relevant parallel and overlapping research findings from the field of social cognition and on the Implicit Association Test are also outlined. New preliminary data obtained with both normal and sex offender populations are described in order to illustrate how behavior-analytically conceived implicit tests may have potential as investigative tools for assessing histories of sexual arousal conditioning and derived stimulus associations. It is concluded that popular implicit tests are likely sensitive to conditioned and derived stimulus associations in the history of the test-taker rather than 'unconscious cognitions', per se

Discussing sexual function in the cardiology practice

BACKGROUND: In patients with cardiovascular disease, sexual dysfunction is frequently encountered. Erectile dysfunction shares the same modifiable risk factors as coronary artery disease and the fear of triggering cardiovascular events can create stress and anxiety impacting the sexual lives of patients and their partners. To optimise healthcare, knowledge of cardiologists' attitude and practice patterns regarding the discussion about sexual function is essential. METHODS: A 31-itemed anonymous questionnaire was mailed to 980 members of the Netherlands Society of Cardiology (cardiologists and residents in cardiology training). The questionnaire addressed awareness, knowledge and practice patterns about sexual dysfunction in cardiac patients. RESULTS: Of the cardiologists 53.9 % responded. Sixteen percent stated to discuss sexual function regularly. In the past year, an estimated mean of 2 % of patients was referred for help with a sexual problem. The majority (70 %) of cardiologists advised patients never or seldom about resuming sexual activity after myocardial infarction. PDE5-inhibitor use was assessed by 19.4 % of the cardiologists. Important reasons not to discuss sexual function were lack of initiative of the patient (54 %), time constraints (43 %) and lack of training on dealing with SD (35 %). Sixty-three percent of the cardiologists stated they would be helped with a directory of sexual healthcare professionals where they can refer patients to. CONCLUSION: Sexuality is not routinely discussed in the cardiology practice. Explanations for the lack of attention toward sexual matters are ambiguities about responsibility and a lack of time, training and experience regarding the communication and treatment of sexual dysfunction.Development and application of statistical models for medical scientific researc
