Complex PTSD, interpersonal trauma and relational consequences: Findings from a treatment-receiving Northern Irish sample

Background:
The relationship between PTSD and complex PTSD remains unclear. As well as further addressing this issue, the current study aimed to assess the degree to which DESNOS (complex PTSD) was related to interpersonal trauma and had relational consequences.

Methods:
Eighty one treatment-receiving participants with a history of exposure to the ‘Troubles’ in Northern Ireland, were assessed on various forms of interpersonal trauma, including exposure to the Troubles, and measures of interpersonal and community connectedness.

Results:
DESNOS symptom severity was related to childhood sexual abuse and perceived psychological impact of Troubles-related exposure. A lifetime diagnosis of DESNOS was related to childhood Troubles-related experiences, while a current diagnosis of DESNOS was associated with childhood emotional neglect. PTSD avoidance predicted current DESNOS diagnosis and severity. Feeling emotionally disconnected from family and friends (i.e., interpersonal disconnectedness) was related to all three indices of DESNOS (i.e., lifetime diagnosis, current diagnosis and current symptom severity).

Limitations:
Sample characteristics (i.e., treatment-receiving) and size may limit the generalizability of findings.

Conclusions:
Complex PTSD is associated with PTSD but when present should be considered a superordinate diagnosis.

Bronchoalveolar lavage findings suggest two different forms of childhood asthma

Background: It seems plausible that children with atopy and persistent asthma symptoms will, like their adult counterparts, have chronic airways inflammation. However, many young children with no other atopic features have episodic wheezing that is triggered solely by viral respiratory infections. Little is known as to whether airways inflammation occurs in these two asthma patterns during relatively asymptomatic periods.

Methods: Using a non-bronchoscopic bronchoalveolar lavage (BAL) procedure on children presenting for an elective surgical procedure, this study has investigated the cellular constituents of BAL fluid in children with a history of atopic asthma (AA) non-asthmatic atopic children (NAA) or viral associated wheeze (VAW).

Results: A total of 95 children was studied: 52 with atopic asthma (8.0 years, range 1.1-15.3, 36 male), 23 with non-asthmatic atopy (median age 8.3 years, range 1.7-13.6, 11 male) and 20 with VAW (3.1 years, range 1.0-8.2, 13 male). No complications were observed during the lavage procedure and no adverse events were noted post-operatively. Total lavage fluid recovered was similar in all groups and the total cell numbers were higher in the VAW group. Eosinophil (P< 0.005) and mast cell (/'<0.05) numbers were significantly elevated in the group with atopic asthma.

Conclusions: During relatively asymptomatic periods there is on-going airways inflammation, as demonstrated by eosinophil and mast cell recruitment, in children with asthma and atopy but not in children with viral associated wheeze or atopy alone. This strongly suggests that there are different underlying pathophysiologicai mechanisms in these two groups of children who wheeze.

Sexual size dimorphism and reproductive investment by female spiders: A comparative analysis

We investigate the association between female reproductive investment, absolute size, and sexual size dimorphism in spiders to test the predictions of the fecundity-advantage hypothesis. The relationships between absolute size and sexual size dimorphism and aspects of female reproductive output are examined in comparative analyses using phylogenetically independent contrasts. We provide support for the idea that allometry for sexual dimorphism is the result of variation in female size more so than male size. Regression analyses suggest selection for increased fecundity in females. We argue that fecundity selection provides the only general explanation for the evolution of sexual size dimorphism in spiders.

Synthesis of the alkaloid homaline in ( ) and natural (S,S)-(-) forms, using amination and transamidative ring expansion in liquid ammonia.

CAN 120:164608 AN 1994:164608 CAPLUS (Copyright (C) 2009 ACS on SciFinder (R)) Abstract The alkaloid homaline I was prepd. in (?) and natural (S,S)-(-) forms. Linking of 2-azacyclooctanone units either directly or successively using 1,4-dihalogenobutanes or 1,4-dihalogenobut-2-ynes is examd. (?)-5-Methyl-4-phenyl-1,5-diazacyclooctan-2-one is first made by a 2,2'-dithiodipyridine/triphenylphosphine-mediated cyclization, and then by amination and transamidative ring expansion from N-(3-chloropropyl)-4-phenylazetidin-2-one in liq. ammonia, followed by N-methylation. Coupling through a 1,4-dihalogenobutane of either the N-methylated azalactam, or the unmethylated azalactam followed by methylation, gave homaline in (?) and meso forms. (R)-(-)-phenylglycine was converted via (S)-?-phenyl-?-alanine into an (S)-?-lactam which was then alkylated with 1-bromo-3-chloropropane, and aminated and ring expanded in liq. ammonia. Coupling of the homochiral azalactam (2 mol) so formed with 1,4-dibromobutane, followed by N-methylation, gave (S,S)-(-)-homaline identical with the natural material.

Bronzino’s allegory of ‘Venus and Cupid’: An exemplary image for contemporary sexual health promotion?

Recent sexual health promotion strategies have veered between a negative emphasis on the deleterious consequences of sexually transmitted infections, and a more positive, eroticized approach to safer sex. The differences in approach are starkly reflected in the images chosen to illustrate them. We note that there are problems with both approaches. The main purpose of this review is to demonstrate how this dichotomy was transcended by the sixteenth century Florentine Mannerist painter, Agnolo Bronzino, in his allegory on syphilis

Vetting Sexual Offenders: State Over-extension, the Punishment Deficit and the Failure to Manage Risk

This article examines the state regulation of sexual offenders in the particular context of pre-employment vetting. A successive range of statutory frameworks have been put in place, culminating in the Safeguarding Vulnerable Groups Act 2006, to prevent unsuitable individuals from working with the vulnerable, and children in particular. Contemporary legislative and policy developments are set against a backdrop of broader concerns in the area of crime and justice, namely risk regulation, preventative governance and ‘precautionary logic.’ Proponents of these approaches have largely ignored concerns over their feasibility. This article specifically addresses this fissure within the specific field of vetting. It is argued that ‘hyper innovation’ and state over-extension in this area are particularly problematic and have resulted in exceptionally uncertain and unsafe policies. These difficulties relate principally to unrealistic public expectations about the state’s ability to control crime; unintended and ambiguous policy effects; and ultimately the failure of the state to deliver on its self-imposed regulatory mandate to effectively manage risk.
