The prevalence and correlates of childhood sexual abuse in a national sample of Canadian women
This study examined the prevalence and correlates of childhood sexual abuse (CSA) among a large nationally representative sample of Canadian women (age 20-64). Among the 7,862 women age 20 through 64 who participated in the Canadian Community Health Survey of Mental Health (CCHS-MH; Statistics Canada, 2013), 1027 (13.01%) reported a history of CSA prior to age 16. Data associated with 2,054 participants were extracted from the Canadian Community Health Survey of Mental Health (CCHS-MH; Statistics Canada, 2013) and further analyzed. Women who reported a history of CSA were significantly more likely to meet diagnostic criteria (lifetime and 12-month) for all psychiatric disorders examined in the present analysis including major depressive disorder, general anxiety disorder, substance and alcohol use disorders, and bipolar disorder compared to an age-matched sample of women without a CSA history. Lifetime and 12-month suicidal ideation were also significantly higher among those women with a CSA history, along with prevalence of a prior PTSD diagnosis. Significantly poorer outcomes were observed for those women with a CSA history across all socio-demographic (marital status, level of education, personal income) and quality of life (community belonging, self-rated mental health, life satisfaction) variables included in the present analysis. Findings were discussed within the context of existing research on the prevalence and correlates of CSA internationally and within Canada
A lesson on interrogations from detainees: Predicting self-reported confessions and cooperation
The ability to predict confessions and cooperation from the elements of an interrogation was examined. Incarcerated men (N = 100) completed a 50-item questionnaire about their most recent police interrogation, and regression analyses were performed on self-reported decisions to confess and cooperate. Results showed that the likelihood of an interrogation resulting in a confession was greatest when evidence strength and score on a humanitarian interviewing scale were high, and when the detainee had few previous convictions or did not seek legal advice. We also found that the level of cooperation was greatest when the humanitarian interviewing score was high, and when previous convictions were low. The implications of the findings for interrogation practices are discussed
A Phase 2, Double-Blind, Randomized, Dose-Ranging Trial Of Reldesemtiv In Patients With ALS
To evaluate safety, dose response, and preliminary efficacy of reldesemtiv over 12 weeks in patients with amyotrophic lateral sclerosis (ALS). Methods: Patients (â€2 years since diagnosis) with slow upright vital capacity (SVC) of â„60% were randomized 1:1:1:1 to reldesemtiv 150, 300, or 450 mg twice daily (bid) or placebo; active treatment was 12 weeks with 4-week follow-up. Primary endpoint was change in percent predicted SVC at 12 weeks; secondary measures included ALS Functional Rating Scale-Revised (ALSFRS-R) and muscle strength mega-score. Results: Patients (N = 458) were enrolled; 85% completed 12-week treatment. The primary analysis failed to reach statistical significance (p = 0.11); secondary endpoints showed no statistically significant effects (ALSFRS-R, p = 0.09; muscle strength mega-score, p = 0.31). Post hoc analyses pooling all active reldesemtiv-treated patients compared against placebo showed trends toward benefit in all endpoints (progression rate for SVC, ALSFRS-R, and muscle strength mega-score (nominal p values of 0.10, 0.01 and 0.20 respectively)). Reldesemtiv was well tolerated, with nausea and fatigue being the most common side effects. A dose-dependent decrease in estimated glomerular filtration rate was noted, and transaminase elevations were seen in approximately 5% of patients. Both hepatic and renal abnormalities trended toward resolution after study drug discontinuation. Conclusions: Although the primary efficacy analysis did not demonstrate statistical significance, there were trends favoring reldesemtiv for all three endpoints, with effect sizes generally regarded as clinically important. Tolerability was good; modest hepatic and renal abnormalities were reversible. The impact of reldesemtiv on patients with ALS should be assessed in a pivotal Phase 3 trial.

Modelling self reported confessions and cooperation with police interrogators
This study modelled self-reported confessions and cooperation with police interrogators.
Incarcerated men (N = 100) were interviewed about their most recent police interrogation.
A logistic regression analysis was performed to predict confession decision using nine
predictors: Humanitarian Style, Legal Advice, Interrogation Length, Perception of
Evidence, Age, Previous Conviction, Number of Convictions, Offence Seriousness, and
Attitude Toward Police. A model containing Perception of Evidence, Humanitarian Style,
Previous Convictions, Number of Convictions, and Legal Advice predicted confession
decision 79% of the time (versus 60% for a base model). A multiple regression analysis,
using the same predictors, revealed that Humanitarian Style, Previous Convictions, and
Number of Convictions accounted for 29% of the variance in self-reported cooperation.

Mutations in a BTB-Kelch Protein, KLHL7, Cause Autosomal-Dominant Retinitis Pigmentosa
Retinitis pigmentosa (RP) refers to a genetically heterogeneous group of progressive neurodegenerative diseases that result in dysfunction and/or death of rod and cone photoreceptors in the retina. So far, 18 genes have been identified for autosomal-dominant (ad) RP. Here, we describe an adRP locus (RP42) at chromosome 7p15 through linkage analysis in a six-generation Scandinavian family and identify a disease-causing mutation, c.449GâA (p.S150N), in exon 6 of the KLHL7 gene. Mutation screening of KLHL7 in 502 retinopathy probands has revealed three different missense mutations in six independent families. KLHL7 is widely expressed, including expression in rod photoreceptors, and encodes a 75 kDa protein of the BTB-Kelch subfamily within the BTB superfamily. BTB-Kelch proteins have been implicated in ubiquitination through Cullin E3 ligases. Notably, all three putative disease-causing KLHL7 mutations are within a conserved BACK domain; homology modeling suggests that mutant amino acid side chains can potentially fill the cleft between two helices, thereby affecting the ubiquitination complexes. Mutations in an identical region of another BTB-Kelch protein, gigaxonin, have previously been associated with giant axonal neuropathy. Our studies suggest an additional role of the ubiquitin-proteasome protein-degradation pathway in maintaining neuronal health and in disease
The DESI experiment part I: science, targeting, and survey design
DESI (Dark Energy Spectroscopic Instrument) is a Stage IV ground-based dark energy experiment that will study baryon acoustic oscillations (BAO) and the growth of structure through redshift-space distortions with a wide-area galaxy and quasar redshift survey. To trace the underlying dark matter distribution, spectroscopic targets will be selected in four classes from imaging data. We will measure luminous red galaxies up to . To probe the Universe out to even higher redshift, DESI will target bright [O II] emission line galaxies up to . Quasars will be targeted both as direct tracers of the underlying dark matter distribution and, at higher redshifts (), for the Ly- forest absorption features in their spectra, which will be used to trace the distribution of neutral hydrogen. When moonlight prevents efficient observations of the faint targets of the baseline survey, DESI will conduct a magnitude-limited Bright Galaxy Survey comprising approximately 10 million galaxies with a median . In total, more than 30 million galaxy and quasar redshifts will be obtained to measure the BAO feature and determine the matter power spectrum, including redshift space distortions
The DESI Experiment Part II: Instrument Design
DESI (Dark Energy Spectropic Instrument) is a Stage IV ground-based dark energy experiment that will study baryon acoustic oscillations and the growth of structure through redshift-space distortions with a wide-area galaxy and quasar redshift survey. The DESI instrument is a robotically-actuated, fiber-fed spectrograph capable of taking up to 5,000 simultaneous spectra over a wavelength range from 360 nm to 980 nm. The fibers feed ten three-arm spectrographs with resolution between 2000 and 5500, depending on wavelength. The DESI instrument will be used to conduct a five-year survey designed to cover 14,000 deg. This powerful instrument will be installed at prime focus on the 4-m Mayall telescope in Kitt Peak, Arizona, along with a new optical corrector, which will provide a three-degree diameter field of view. The DESI collaboration will also deliver a spectroscopic pipeline and data management system to reduce and archive all data for eventual public use
