Does the Organized Sexual Murderer Better Delay and Avoid Detection?

According to the organized–disorganized model, organized sexual murderers adopt specific behaviors during the commission of their crimes that contribute to avoiding police detection. The current study examines the effect of sexual murderers’ organized behaviors on their ability to both delay and/or avoid police detection. Using a combination of negative binomial and logistic regression analyses on a sample of 350 sexual murder cases, findings showed that although both measures of delaying and avoiding detection are positively correlated, different behavioral patterns were observed. For instance, offenders who moved the victim’s body were more likely to avoid detection but the victim’s body was likely to be recovered faster. Moreover, victim characteristics have an impact on both measures; however, this effect disappears for the measure of delaying detection once the organized behaviors are introduced. Implications of the findings are discussed.
Prevalence and predictors of carer burden and depression in carers of patients referred to an old age psychiatric service

ABSTRACT Background: Too little is currently known about the prevalence of and risk factors for depression and carer strain among informal carers of community-dwelling elderly mentally ill. This study seeks to assess the prevalence of depression, using the Geriatric Depression Scale-15 (GDS-15), the degree of carer burden/strain, and their risk factors among the primary informal carers of patients referred to our community-based old age psychiatry service. Methods: A cross-sectional study design was used, with the subjects comprising 100 primary informal carers of patients who live at home and were referred to our service. The main carer measures were the GDS-15 and an adapted version of Gilleard's Strain Scale. Patients were assessed the Clifton Assessment Procedure for the Elderly–Survey version, the GDS-15 and the Mini-mental State Examination. Results: Depression was found in 21% of the carers (a score of 5 or more on the GDS-15). The more problem behaviors identified and the greater the functional impairment of the patient, the higher the strain score deciles and the more likely the carer was to be depressed. Spouses were associated with lower carer strain scores. Patient diagnoses did not affect carer depression or carer strain. Conclusion: We found high levels of depression in the primary carers of community-dwelling patients attending an old age psychiatric service. The patients' behavior and their cognitive and functional ability conferred greater risk of carer depression or strain than their diagnosis. These risk factors may help identify carers at risk of strain and depression.
Photodynamic therapy of facial squamous cell carcinoma in cats using a new photosensitizer

Photodynamic therapy has been shown to be an effective treatment modality for surface‐oriented neoplasms of the skin, respiratory, gastrointestinal, and urogenital systems. The purpose of this study was to assess the safety and efficacy of photodynamic therapy using a new photosensitizer in the treatment of squamous cell carcinomas of the feline facial skin.
Anatomic Suture Anchor Versus the Broström Technique for Anterior Talofibular Ligament Repair

Background: Despite the popularity of the Broström procedure for secondary repair of chronic lateral ankle instability, there have been no biomechanical studies reporting on the strength of this secondary repair method, whether using suture fixation or suture anchors. Hypothesis: The purpose of our study was to perform a biomechanical comparison of the ultimate load to failure and stiffness of the traditional Broström technique using only a suture repair compared with a suture anchor repair of the anterior talofibular ligament (ATFL) at time zero. We believed that fixation strength of the suture anchor repair would be closer to the strength of the native ligament and allow more aggressive rehabilitation. Study Design: Controlled laboratory study. Methods: Twenty-four fresh-frozen cadaveric ankles were randomly divided into 4 groups of 6 specimens. One group was an intact control group, and the other groups consisted of the traditional Broström and 2 suture anchor modifications (suture anchors in talus or fibula) of the Broström procedure. The specimens were loaded to failure to determine the strength and stiffness of each construct. Results: In load-to-failure testing, ultimate failure loads of the Broström (68.2 ± 27.8 N; P = .013), suture anchor fibula (79.2 ± 34.3 N; P = .037), and suture anchor talus (75.3 ± 45.6 N; P = .027) repairs were significantly lower than that of the intact (160.9 ± 72.2 N) ATFL group. Stiffness of the Broström (6.0 ± 2.5 N/mm; P = .02), suture anchor fibula (6.8 N/mm ± 2.7; P = .05), and suture anchor talus (6.6 N/mm ± 4.0; P = .04) repairs were significantly lower than that of the intact (12.4 N/mm ± 4.1 N/mm) ATFL group. The 3 repair groups were not significantly different from each other, but all 3 were substantially lower in strength and stiffness when compared to the intact ATFL. Conclusion: The use of suture anchors to repair the ATFL produces a repair that can withstand loads to failure similar to the suture-only Broström repair. However, all 3 repair groups were much weaker than the intact, uninjured ATFL. Clinical Relevance: Biomechanically, the results show that both suture anchor and direct suture repair of the ATFL provide similar strength and stiffness. Unfortunately, these methods provide less than half the strength and stiffness of the native ATFL at time zero. As a result, regardless of the repair method, it is necessary to sufficiently protect the repair to avoid premature failure.
Environmental changes during secondary succession in a tropical dry forest in Mexico

Abstract: Vegetation and environment change mutually during secondary succession, yet the idiosyncrasies of the vegetation effect on the understorey environment are poorly understood. To test whether the successional understorey environment changes predictably and is shaped by the structure and seasonality of tropical dry forests, we estimated basal area and vegetation cover, and measured understorey temperature, light and moisture conditions, in 17 plots forming a 60-y chronosequence and a mature forest. Light and air and soil temperature decreased with time (75−15% of open-sky radiation, 31.7−29.3 °C, and +2.5 °C to −0.5 °C relative to ambient, respectively), whereas relative humidity increased (67−74%). Soil water availability increased with early-successional development (−45 to −1 kPa) but decreased afterwards (to −18 kPa). The first axis of a PCA of the rainy-season environment explained 60% of the variation and was strongly related to air temperature and relative humidity. During tropical dry-forest succession, such factors may be more important than light, the reduction in which is not extreme compared with taller and more vertically stratified wet forests. Seasonality significantly affected the successional environmental gradients, which were marked mainly during the wet season. Environmental heterogeneity was higher in the wet than in the dry season, and larger for resources (light and water) than for conditions (temperature and humidity). The wet-season increase in environmental heterogeneity potentially creates differential growing scenarios; the environmental harshness of the dry season would mostly challenge seedling survival.
Thiopurine drug adverse effects in a population of New Zealand patients with inflammatory bowel disease

The thiopurine drugs, azathioprine and 6‐mercaptopurine are effective in the treatment of inflammatory bowel disease (IBD). However, their use is limited by serious adverse effects that can lead to cessation of therapy. The incidence of these adverse effects has been reported to be approximately 9% but in Christchurch it was felt that the incidence was higher.
Antidepressant effects of the water extract from Taraxacum officinale leaves and roots in mice

Abstract Context: The leaves and roots of the Taraxacum officinale F. (Asteraceae) is widely used as traditional medicinal herb in Eastern Asian countries. Objective: In the present study, the antidepressant-like effects of the water extract of T. officinale (WETO) leaves and roots were investigated in mice using forced swimming test (FST), tail suspension test (TST) and open field test (OFT). Materials and methods: Effects of acute (1-day) and chronic treatments (14-days) with WETO (50, 100 and 200 mg/kg) on the behavioral changes in FST, TST and OFT, and the serum corticotrophin releasing factor (CRF), adrenocorticotropic hormone (ACTH) and corticosterone concentration were assessed in mice. Results: Chronic treatment (14-days) with WETO at the doses of 50, 100 and 200 mg/kg significantly decreased the immobility time in both FST (92.6, 85.1 and 77.4 s) and TST (84.8, 72.1 and 56.9 s). Acute treatment (1-day) with WETO at a dose of 200 mg/kg also markedly decreased the immobility time in both FST (81.7 s) and TST (73.2 s). However, all treatments did not affect the locomotor activity in the OFT. Moreover, FST induced a significant increase in serum CRF (5.8 ng/ml), ACTH (104.7 pg/ml) and corticosterone levels (37.3 ng/ml). Chronic treatment (14-days) with WETO decreased the serum CRF (200 mg/kg: 3.9 ng/ml) and corticosterone (50 mg/kg: 29.9 ng/ml; 100 mg/kg: 22.5 ng/ml; 200 mg/kg: 19.8 ng/ml) levels. Discussion and conclusion: These results clearly demonstrated the antidepressant effects of WETO in animal models of behavioral despair and suggested the mechanism involved in the neuroendocrine system.
Toward Scalable Verification for Safety-Critical Deep Networks

The increasing use of deep neural networks for safety-critical applications, such as autonomous driving and flight control, raises concerns about their safety and reliability. Formal verification can address these concerns by guaranteeing that a deep learning system operates as intended, but the state-of-the-art is limited to small systems. In this work-in-progress report we give an overview of our work on mitigating this difficulty, by pursuing two complementary directions: devising scalable verification techniques, and identifying design choices that result in deep learning systems that are more amenable to verification.
Characterization of the N-terminal and C-terminal domains of human apolipoprotein(a): relevance to fibrin binding.

The structural domains of human apolipoprotein(a) (apo(a)) in the lipoprotein(a) (Lp(a)) particle have been recently investigated by limited proteolysis [Huby, T. , Doucet, C. , Dieplinger, H. , Chapman, J., & Thillet, J. (1994) Biochemistry 33, 3335-3341]. We have shown that apo(a) can be cleaved into two structural domains: one was of constant size (170 kDa) and corresponded to the C-terminal (Cter) domain of apo(a). This domain was linked by a disulfide bond to apo B100. By contrast, the N-terminal (Nter) domain, whose size varied according to the digested apo(a) isoform, was not linked to apo B100. We now describe the purification of these apo(a) domains and their interaction with fibrin surfaces in an in vitro binding assay. The Nter domain of apo(a) was purified as a soluble protein in a two-step procedure which involved sequential use of a heparin-Sepharose column and a lysine-Sepharose column. The Cter domain of apo(a), which remained in disulfide linkage with apo B100 of Lp(a), was isolated as a lipoprotein particle by a combination of chromatographic steps on heparin-Sepharose and Q-Sepharose columns. This particle, termed "mini-Lp(a)", appeared homogeneous in nondenaturing polyacrylamide gels and exhibited a particle size (285 A) which was intermediate between that of Lp(a) (300 A) and LDL (265 A). The cleavage site between the respective apo(a) domains was determined by N-terminal sequencing of the purified Cter domain. Such cleavage occurred between residues 3532 and 3533, which are located in the interkringle region between apo(a) kringles 4(4) and 4(5). (ABSTRACT TRUNCATED AT 250 WORDS)
“Interactive surfaces” technology as a potential tool to stimulate physical activity in psychogeriatric nursing home residents

Abstract Purpose: The aims of this study were to determine whether and how psychogeriatric nursing home residents would respond to the interactive surfaces on the floor without receiving instructions and to determine how long residents would be physically active. Methods: The “interactive surfaces” technology includes different graphic shapes that are projected through a beamer on a floor. The surfaces are “activated” by a person’s movements in the area of the projection field, which is detected by an infrared camera. Every day for 1 h during an 11-day period one of seven different projections was shown. Spontaneous observed physical responses were counted, clustered and visualized in a tree diagram. Duration of physically responses was measured per session and during the total observation period of 11 h. Results: During 343 of 490 observations residents (n = 58) noticed the interactive surface and in 148 observations they engaged physically. In total, 4067 s (1 h, 7 min and 47 s) of physical activity were measured. Individual times that residents were active ranged from 3 to 415 s. Conclusions: Interactive surfaces technology may be a promising tool in psychogeriatric nursing home residents to stimulate physical activity. Further research is needed to assess its full potential. Implications for Rehabilitation Innovative technology used to adapt the environment might stimulate nursing home residents to become more physically active. The use of innovative technologies may increase physical activity without necessarily increasing the workload of care professionals.
Production of extracellular material by streptococci associated with subacute bacterial endocarditis

Six strains of viridans streptococci isolated from confirmed cases of subacute bacterial endocarditis were studied for production of extracellular material. All six strains, when grown to the exponential phase, produced exoproducts that had similar elution profiles on a G-100 Sephadex column. Since essential nutrients, such as amino acids, may be periodically growth limiting to streptococci in the fibrin-covered lesions on heart valves, the potential to elaborate extracellular protein and other material by streptococci that were deprived of essential amino acids was studied. Examination of supernatant fluids from cultures of Streptococcus MG intermedius deprived of glutamate and cystine revealed the presence of a complex mixture of extracellular materials in amounts comparable to those produced by normallly growing cells, Although only a slight (21 to 24%) increase in total protein occurred during amino acid deprivation of 12 h, the extracellular material contained numerous protein components, several of which demonstrated proteolytic activity. On a cell dry weight basis, the amino acid-deprived cells produced four-to eightfold more protease(s) than did exponential cells grown in complete medium. These results demonstrate that viridans streptococci are capable of elaborating potentially damaging compounds even when their multiplication has been arrested by nutritional deprivation.
Pharmacodynamic effects of clopidogrel in pediatric cardiac patients: A comparative study of platelet aggregation response

Little data on pediatric percent platelet aggregation (%PA) exist in the literature, particularly in cardiac patients and in response to clopidogrel. The objectives were to estimate the %PA range expected in pediatric patients and to measure the clopidogrel effect on %PA in the PICOLO (Platelet Inhibition in Children on Clopidogrel) trial. To estimate a neonatal/infant %PA response range, %PA induced by 5 µM adenosine diphosphate (ADP) was assessed using light transmission aggregometry in 16 cord and 11 normal adult blood samples and prior to clopidogrel therapy in 49 neonatal and 49 infant/toddler cardiac patients enrolled in PICOLO. The %PA induced by 5 µM thrombin receptor-activating peptide (TRAP) was also assessed for 10 neonates and 21 infants/toddlers enrolled in PICOLO and compared with 11 adult samples. Percent inhibition of platelet aggregation (%IPA) induced by 5 µM ADP at steady-state clopidogrel levels was assessed in 33 neonates and 39 infants/toddlers. ADP-induced %PA was lowest in cord blood samples, intermediate in study neonates and infants/toddlers, and highest in adults. Similarly, TRAP-induced platelet aggregation was lower in neonates and infants/toddlers than adults. For all groups, %PA and %IPA were highly variable, with 11% of neonates and 13% of infants/toddlers showing <10% IPA. In conclusion, ADP- and TRAP-induced %PA is lower in pediatric cardiac patients than normal adults, but highly variable in both. The lower baseline %PA may explain why the pediatric clopidogrel dose providing 30–50% IPA (0.20 mg/kg/day) is lower than a simple weight-based extrapolation of the adult dose (75 mg/day) providing similar inhibition.
Influence of a walking program on the metabolic risk profile of obese postmenopausal women

Objective: Menopause transition is associated with an increased prevalence of metabolic syndrome (MS), which may partly explain the higher coronary heart disease risk. The aim of this study was to examine the impact of a 16-week walking program on the metabolic risk profile of women 50 to 65 years old whose body mass index ranged from 29 to 35 kg/m2. Methods: A total of 153 postmenopausal women were subjected to three sessions per week of 45-minutes of walking at 60% of their heart rate reserve. At baseline, 46 and 84 women were characterized by one and two or more determinants of MS, respectively, whereas 23 women did not show this condition. Body composition, resting blood pressure, fasting lipid-lipoprotein profile, and cardiorespiratory fitness (CRF) were measured before and after exercise. Results: In the whole sample of 153 women, CRF estimated by V˙o2max increased in response to walking (P < 0.0001). Endurance training promoted body weight and fat mass losses and reduced waist girth and blood pressure, whereas it decreased plasma triglyceride, cholesterol, and low-density lipoprotein cholesterol levels and increased high-density lipoprotein cholesterol concentrations (P < 0.0001). Improvements in lipid-lipoprotein levels were not associated with increases in CRF but seemed to be dependent on reduced body fatness. However, the greatest ameliorations in metabolic risk profile were found in women characterized by two or more determinants of MS at baseline than in the two other groups (0.05 < P < 0.0001). Conclusion: A moderate-intensity physical activity is thus sufficient to reduce the metabolic risk profile of postmenopausal women characterized by the presence of one or several clinical features of MS but without overt coronary heart disease.
Adverse events related to the new psychoactive substance 3-fluorophenmetrazine – results from the Swedish STRIDA project

Abstract Background: New psychoactive substances (NPS) are often poorly pharmacologically documented and the production is unregulated, implying high risks for toxic side effects. This report from the STRIDA project describes analytically confirmed non-fatal intoxications involving the phenmetrazine analogue 3-fluorophenmetrazine (3-FPM). Study design and methods: Observational case series of patients with suspected acute NPS exposure requiring hospital care. Blood and urine samples were collected from patients presenting in emergency departments (ED) or intensive care units (ICU), after consultation with the Swedish Poisons Information Centre (PIC). Laboratory analysis was performed by multi-component liquid chromatography–mass spectrometry. Clinical data were collected during PIC consultations and retrieved from medical records. Results: From November 2014 to October 2015, eight cases were registered as 3-FPM or “phenmetrazine” intoxications at the PIC after consultation. During the same period, analysis of STRIDA project samples confirmed 3-FPM use in a total of 19 patients (84% men) aged 22–54 (median 30) years. 3-FPM was detected in 15 out of 19 serum (2.7–1416 ng/mL) and in 14 out of 14 urine (1.0–6857 μg/mmol creatinine) samples. All patients were also tested positive for other psychoactive substances, with benzodiazepines being most common (57% of the cases). Ten patients were monitored in the ED for <4 h, while six needed ICU monitoring of which five were graded as severe intoxications (Poisoning Severity Score 3). Prominent clinical signs were tachycardia (47%), depressed consciousness (42%), agitation/anxiety (37%), delirium (37%), dilated pupils (26%), and seizures (16%). All patients survived. Conclusion: In 19 patients testing positive for 3-FPM, a high incidence of severe clinical features was demonstrated. However, as all patients had also used other psychoactive substances, it was difficult to identify a unique toxidrome for 3-FPM. The results further showed that many 3-FPM intoxications would have been missed, if relying solely on information from PIC consultations. These results emphasize the importance of performing bioanalytical investigation in cases of suspected NPS intoxication.
Confusion in the hospitalized elderly: Incidence, onset, and associated factors

Seventy-one non-surgical patients over age 60 years were studied to obtain information about the incidence, onset and variables associated with the onset of confusion. The incidence of confusion was 38%; 27 of the 71 subjects developed confusion during hospitalization. Nineteen of the 27 patients developed confusion by the second day of hospitalization; no new cases of confusion were detected after the sixth day of hospitalization. An examination of the psychophysiologic variables associated with the onset of confusion produced a profile of the confused elderly patient. Confused patients were: hypernatremic, hypokalemic, hyperglycemic, hypotensive, had elevated blood levels of creatinine and urea nitrogen, received more medications, were more frequently perceived by nurses as confused, had more orienting objects in their immediate environment, and fewer interactions with significant others. Recommendations for the continued investigation and care of confused patients are offered.
The selective vulnerability of brainstem nuclei to Alzheimer's disease

In a study of thioflavin S–stained serial sections from the entire brainstem, we found that the inferior and superior colliculi and the autonomic, monoaminergic, cholinergic, and classical reticular nuclei were affected with varying degrees of severity and frequencies in 32 patients with Alzheimer's disease, whereas no changes were seen in the brainstems of 26 control subjects. The majority of the affected nuclei in patients with Alzheimer's disease exhibit either neurofibrillary tangles or senile plaques, and only a few display both. However, when sections were immunostained with the antibodies 10D5 and AT8 or ALZ50, both β‐amyloid and hyperphosphorylated epitopes of tau protein were found to be present in various concentrations in all the affected nuclei. Our findings suggest that each brainstem nucleus has a distinct vulnerability to Alzheimer's disease–related pathological changes. Given that each nucleus has idiosyncratic neuroanatomical connections and prevailing neurochemical characteristics, the heterogeneous collection of brainstem nuclei can be considered a suitable anatomical ground for further investigation of selective vulnerability in Alzheimer's disease. The finding of severe pathological changes in some brainstem nuclei also raises the possibility that the dysfunction of these nuclei may contribute to the cognitive defects and increased rates of morbidity and mortality in patients with Alzheimer's disease.
