BACKGROUND CONTEXT: Sacral fractures are a rare but potentially devastating complication. Long-fusion constructs including the sacrum that do not extend to the pelvis may result in sacral fractures. Besides established risk factors including gender, age and number of levels fused, body mass index (BMI), pelvic parameters and bone mineral density (BMD) have also been proposed as potential risk factors for postoperative sacral fractures. The literature supporting this, however, is limited...

INTRODUCTION: Amyloid PET data are commonly expressed as binary measures of cortical deposition. However, not all individuals with high cortical amyloid will experience rapid cognitive decline. Motivated by postmortem data, we evaluated a three-stage PET classification: low cortical; high cortical, low striatal; and high cortical, high striatal amyloid; hypothesizing this model could better reflect Alzheimer's dementia progression than a model based only on cortical measures. METHODS: We classified PET data from 1433 participants (646 normal, 574 mild cognitive impairment, and 213 AD), explored the successive involvement of cortex and striatum using 3-year follow-up PET data, and evaluated the associations between PET stages, hippocampal volumes, and cognition...

Non-arteritic anterior ischemic optic neuropathy (NAION) is a common cause of acute optic neuropathy in the elderly. The role of the genetic polymorphisms of Atonal Homolog 7 (ATOH7), Endothelin-1 (ET-1) and Angiotensin Converting Enzyme (ACE) in NAION and the combined effects of the gene-gene and gene-medical comorbidities on NAION were not clear. We conducted a perspective, case-control study. 71 NAION patients and 142 age and sex-matched healthy controls were enrolled. Single nucleotide polymorphisms of ATOH7 (rs1900004), ET-1 (rs5370) and ACE (rs1799752) were identified by polymerase chain reaction (PCR) method and all PCR products were screened with Sanger sequencing...

Rachel K Jones
OBJECTIVES: To assess factors associated with pregnancy fatalism among U.S. adult women. STUDY DESIGN: I used data from the Change and Consistency in Contraceptive Use study, which collected information from a national sample of 4634U.S. women aged 18-39 at baseline (59% response rate). I assessed pregnancy fatalism based on agreement with the statement: "It doesn't matter whether I use birth control, when it is my time to get pregnant, it will happen." I compare fatalism among all respondents to fatalism among respondents who were trying to get pregnant and those who did not want to get pregnant but were not using contraception...

BACKGROUND: Sperm DNA fragmentation measured by different techniques make comparisons impossible due to lack of standardization. Induction of DNA damage after sperm preparation in the entire fraction has been observed on independent occasions but findings are not consistent. METHODS: Men presenting at a University hospital setup for infertility treatment. DNA damage via TUNEL assay was validated on fresh semen samples, as conventional semen parameters, to reduce variability of results...

Nonalcoholic fatty liver disease (NAFLD) is a major cause of chronic liver disease in Western population. We investigated the effect of nonalcoholic fatty liver disease (NAFLD) and diabetes mellitus on CYP3A4 activity in human liver tissue from brain dead donors (N=74). Histopathologically graded livers were grouped into normal (n=24), nonalcoholic fatty liver (NAFL, n=26) and nonalcoholic steatohepatitis (NASH, n=24) categories. The rate of conversion of midazolam to its 1-hydroxy metabolite was used to assess in vitro CYP3A4 activity in human liver microsomes (HLM)...

This study investigates category goodness judgments of /r/ in adults and children with and without residual speech errors (RSEs) using natural speech stimuli. Thirty adults, 38 children with RSE (ages 7-16) and 35 age-matched typically developing (TD) children provided category goodness judgments on whole words, recorded from 27 child speakers, with /r/ in various phonetic environments. The salient acoustic property of /r/ - the lowered third formant (F3) - was normalized in two ways. A logistic mixed-effect model quantified the relationships between listeners' responses and the third formant frequency, vowel context and clinical group status...

This study evaluated whether the Test of Gross Motor Development 3 (TGMD-3) is a reliable tool to compare children with and without mental and behavioral disorders across gross motor skill domains. A total of 1,075 children (aged 3-11 years), 98 with mental and behavioral disorders and 977 without (typically developing), were included in the analyses. The TGMD-3 evaluates fundamental gross motor skills of children across two domains: locomotor skills and ball skills. Two independent testers simultaneously observed children's performances (agreement over 95%)...

Although adoptive families have been shown to provide a protective context for human development, some adopted children and adolescents are at increased risk for psychological adjustment problems. On the other hand, little is known about psychological adjustment of young adult adoptees. The aim of this study is to analyze the mental health and legal substance consumption (tobacco and alcohol) of young adults (n = 134) who were domestically adopted by Spanish families. Young adults showed significantly worse scores on the Symptom Check-List-90-R (Derogatis, 1975) and also more substance use than did the Spanish general population, but fewer difficulties than did the clinical population...

BACKGROUND: Transposon-mediated, non-viral gene delivery is a powerful tool for generating stable cell lines and transgenic animals. However, as multi-copy insertion is the preferred integration pattern, there is the potential for uncontrolled changes in endogenous gene expression and detrimental effects in cells or animals. Our group has previously reported on the generation of several transgenic cattle by using microinjection of the Sleeping Beauty (SB) and PiggyBac (PB) transposons and seeks to explore the long-term effects of this technology on cattle...

BACKGROUND: Congenital disorders of glycosylation (CDG) are a growing group of rare genetic disorders. The most frequently used screening method is sialotransferrin profiling using isoelectric focussing (IEF). Capillary zone electrophoresis (CZE) may be a simple and fast alternative. We investigated the Capillarys ¬T M CDT assay (Sebia, France) to screen for N-glycosylation disorders, using IEF as gold standard. METHODS: Intra- and interassay precision were established, and analyses in heparin-anticoagulated plasma and serum were compared...

The anterior cruciate ligament reconstruction (ACLR) has become a very common surgical procedure. One of the main success indicators of the surgical procedure is the return to preinjury sporting level. In recent years, reconstructive techniques have been geared toward less morbidity and optimized ligaments process to speed up the recovery of sports activity. This study compares clinical and imaging data, to evaluate the timing of return to sport, of two populations undergoing ACLR using two different techniques: ACLR with hamstring maintaining tibial insertion (MHG) and an all-inside technique with complete hamstring detachment (DHG)...

Diagnosis of seizure imitators in children is often challenging, and individuals with intellectual disability (ID) could be at additional risk of seizure imitator misdiagnosis. We aimed to elucidate distinct features of clinical semiology among children of different intellectual levels, which may help in distinguishing seizure imitators from epilepsy in such individuals. We retrospectively compared semiological features of seizure imitators in children with and without ID captured using video-electroencephalography (video-EEG)...

CONTEXT: The ventriculus terminalis (VT) is a very small ependymal-lined residual lumen in the conus medullaris. It is normally present in all subjects during fetal development. VT in adults appears as an unusual pathology with an uncertain pathogenesis. FINDINGS: In this paper, we described three case reports of symptomatic fifth ventricle cystic dilations. All of them were female and their mean age was 59 years. We treated them surgically and all three patients were improved based on clinical and imaging assessments...

Chronic pain may alter both affect- and value-related behaviors, which represents a potentially treatable aspect of chronic pain experience. Current understanding of how chronic pain influences the function of brain reward systems, however, is limited. Using a monetary incentive delay task and functional magnetic resonance imaging (fMRI), we measured neural correlates of reward anticipation and outcomes in female participants with the chronic pain condition of fibromyalgia (N = 17) and age-matched, pain-free, female controls (N = 15)...

Refeeding Syndrome (RFS) is a well-known group of symptoms which occur after the introduction of enteral or parenteral nutrition in undernourished patients. Intrauterine growth restriction (IUGR) is the equivalent of postnatal RFS following the beginning of feeding. The aggressive parenteral nutrition of neonates with very low birth weight (VLBW) resulting from the termination of intrauterine transplacental nutrition is a source of biochemical disorders. The aim of this study was to analyze metabolic disorders in preterm infants during the 1st week of life and to determine the hypophosphatemia risk factors in low birth weight neonates receiving parenteral nutrition...
