The relationship between physical and sexual abuse and tobacco, alcohol, and illicit drug use among youths in a juvenile detention center

The relationships between child physical and sexual abuse and tobacco, alcohol, and illicit drug use are little understood and underinvestigated. Data gathered from a study of youths in a regional detention center permitted an examination of this issue. The results indicate that the youths' physical and sexual abuse experiences are significantly and positively related to their use of illicit drugs. The implications of these findings for further research are drawn.     

Young adults with α1antitrypsin deficiency identified neonatally: their health, knowledge about and adaptation to the high-risk condition

The psychological and psychosocial consequences of screening for α₁-antitrypsin deficiency (α₁ ATD) were investigated when the subjects were 5–7 years old. The present study was conducted when the subjects were 18–20 years old, the foci of interest being their health, psychosomatic problems, knowledge about α₁ATD and the potential effect of that knowledge on their lives and future family planning. Samples of 61 PiZ and 61 demographically matched control subjects, 18–20 years old, were asked to participate. Written, structured questionnaires covered the following items: basic familial characteristics, psychosomatic symptoms, opinions on medical check-ups, information and views on future α₁ATD screening, whether the knowledge about α₁ATD had affected the life and family planning of α₁ATD individuals. Items concerning the “α₁ATD matter” were excluded in the questionnaires given to the controls. Questionnaire data were obtained from 50 α₁ ATD and 48 control individuals, 41 of each being matched α₁ATD-control pairs. No significant differences were found in demographic or educational backgrounds, psychosomatic complaints such as headache, sleep difficulties, stomach ache, tiredness or anxiety. Lung symptoms occurred more frequently in α₁ATD subjects (p= 0.05). Six per cent of the α₁ATD individuals planned working careers with a high risk of air pollution. The majority (86%) of the α₁ATD subjects perceived the contact with the medical services as positive; 14% as both positive and negative. The information concerning α₁ATD was assessed as satisfactory by 73%, as both good and bad by 17% and as unsatisfactory by 10%. All α₁ATD subjects advocated general screening for α₁ATD, the neonatal period being chosen as optimal by 94%. Half of the α₁ATD individuals thought that the knowledge of their high-risk condition had affected their lives, particularly their awareness of the dangers of smoking and environmental pollution. The majority, 88%, knew that they should avoid smoking to protect their lungs. In conclusion, no negative psychosocial consequences of the neonatal α₁AT-screening were found in early adulthood. The α₁ATD individuals were aware of the dangers of smoking and were of the opinion that α₁ AT-screening should be recommended.     

New antitumor antibiotic, LL-D05139 beta. Fermentation, isolation, structure determination and biological activities

The LL-D05139 complex, containing LL-D05139 beta and azaserine, was recovered from the fermentation filtrate of Glycomyces harbinensis (NRRL 15337). A chemically defined medium was developed which favored the production of LL-D05139 beta. Antibiotic LL-D05139 beta was isolated from the fermentation filtrate by adsorption on granular carbon and further purified by chromatography on microcrystalline cellulose. Acid hydrolysis of LL-D05139 beta gave one molar equivalent each of alanine and serine. Both amino acids were found to have the L-configuration by GC analysis on a chiral column and alanine was assigned to be the N-terminal amino acid by Edman degradation. This information coupled with IR, UV, 1H NMR, 13C NMR and MS spectral data allowed us to assign the structure of LL-D05139 beta as alanylazaserine. LL-D05139 beta demonstrated greater antibacterial and biochemical induction assay activities than azaserine. The two drugs showed similar antitumor activities.     

Unusual manifestations of Langerhans cell histiocytosis of the head and neck

Langerhans cell histiocytosis of the head and neck is an uncommon histiocytic proliferative disorder that often clinically resembles an inflammatory process. A pseudoaneurysm of the external carotid artery was found by contrast-enhanced CT and confirmed by Dopper ultrasonography and angiography in a 9 year old girl with a lytic lesion of the mandible, a prior severe tracheal inflammatory process, and sclerotic lesions of the sphenoid wings. Biopsies of the mandibular lesion, pseudoaneurysm, and trachea demonstrated Langerhans cell histiocytosis. In cases of LCH with head and neck involvement, contrast-enhanced CT allows adequately detailed initial evaluation of the protean manifestations of this disorder.     

Pelvic floor symptoms and quality of life changes during first pregnancy: a prospective cohort study

Introduction and hypothesis

We describe pelvic floor function in nulliparous pregnant women.

Materials and methods

Nulliparous midwifery patients completed the Incontinence Severity Index (ISI), Pelvic Floor Impact Questionnaire (PFIQ-7), Wexner Fecal Incontinence Scale (W), and answered questions about sexual activity and perineal pain at baseline during the first (T1), second (T2), or third trimester (T3) and repeated in late T3. They also underwent a Pelvic Organ Prolapse Quantification (POP-Q) exam at their baseline visit. Data were compared across trimesters. Analysis of variance (ANOVA) and logistic regression accounted for repeated measures and was controlled for age and education.

Results

We recruited 627 women. In T1, 124 women gave baseline data and completed questionnaires; in T2, 403; and in early T3, 96 (496 repeated questionnaires in later T3). Besides an increase in genital hiatus and perineal body (all adjusted p < .05), physical exam measures did not differ between trimesters. As pregnancy progressed, urinary incontinence (UI) (T1 = 33, T2 = 44, T3 = 69% women with ISI >0, all comparisons p < .02) and Incontinence Impact Questionnaire (IIQ-7) scores increased. Fecal incontinence (FI) increased (T1 = 8, T2 = 15, T3 = 16% from T2 to T3, p = .04); the Colorectal–Anal Impact Questionnaire (CRAIQ-7) scores did not. Perineal pain increased (T1 = 17, T2 = 18 and T3 = 40%, all adjusted p < .001), and sexual activity decreased (T1 = 94, T2 = 90, T3 = 77% sexually active, T1 vs T3 and T2 vs T3, p < .001) as pregnancy progressed.

Conclusions

During pregnancy, women experience worsening UI, FI, and perineal pain. UI symptoms are associated with a negative impact on quality of life (QoL). Sexual activity decreased and POP-Q stage did not change.

     

Hemodynamic characteristics of the intestinal microcirculation in renal hypertension

This study investigated the microvascular changes that affect vascular resistance in the rat small intestine during two-kidney, one clip renal hypertension 4 weeks after renal artery stenosis. To study the intestinal microcirculation, a loop of the small intestine was exteriorized with intact circulation and innervation and a section of the bowel wall was prepared for observation with an intravital video microscopy system. Microvascular diameter, pressure, and flow velocity were measured for first, second, and third branch order arterioles and venules, using an image shearing monitor, servo-null micropipette system, and an optical Doppler velocimeter, respectively. The diameters of the first order arterioles and venules were significantly (p less than 0.05) reduced in hypertensive rats; however, diameters were unaltered in smaller second and third order arterioles and venules as compared with normotensive vessels. In hypertensive rats, mean arterial pressure was significantly (p less than 0.05) elevated (47%) and pressures also were elevated significantly (p less than 0.05) throughout the microcirculation, although by a proportionally smaller amount. Total network flow (i.e., first order arteriole flow) was significantly (p less than 0.05) reduced (40%) in hypertensive rats, but volume flows in individual second and third order arterioles were similar to flows measured in normotensive rats. Calculated total network resistance was increased (124%) in hypertensive rats. Thus, the intestinal microcirculation in rats with two-kidney, one clip renal hypertension is disturbed by elevated pressure and decreased total flow. The presence of normal flows in individual second and third order arterioles without any demonstrable difference in their diameters suggests that the predominant cause of elevated resistance across this segment of the intestinal microcirculation is a reduction in the number of perfused small arterioles.     

Effectiveness of a Blended Web-Based Intervention on Return to Work for Sick-Listed Employees With Common Mental Disorders: Results of a Cluster Randomized Controlled Trial

Background

Common mental disorders are strongly associated with long-term sickness absence, which has negative consequences for the individual employee’s quality of life and leads to substantial costs for society. It is important to focus on return to work (RTW) during treatment of sick-listed employees with common mental disorders. Factors such as self-efficacy and the intention to resume work despite having symptoms are important in the RTW process. We developed “E-health module embedded in Collaborative Occupational health care” (ECO) as a blended Web-based intervention with 2 parts: an eHealth module (Return@Work) for the employee aimed at changing cognitions of the employee regarding RTW and a decision aid via email supporting the occupational physician with advice regarding treatment and referral options based on monitoring the employee’s progress during treatment.

Objective

This study evaluated the effect of a blended eHealth intervention (ECO) versus care as usual on time to RTW of sick-listed employees with common mental disorders.

Methods

The study was a 2-armed cluster randomized controlled trial. Employees sick-listed between 4 and 26 weeks with common mental disorder symptoms were recruited by their occupational health service or employer. The employees were followed up to 12 months. The primary outcome measures were time to first RTW (partial or full) and time to full RTW. Secondary outcomes were response and remission of the common mental disorder symptoms (self-assessed).

Results

A total of 220 employees were included: 131 participants were randomized to the ECO intervention and 89 to care as usual (CAU). The duration until first RTW differed significantly between the groups. The median duration was 77.0 (IQR 29.0-152.3) days in the CAU group and 50.0 (IQR 20.8-99.0) days in the ECO group (hazard ratio [HR] 1.390, 95% CI 1.034-1.870, P=.03). No significant difference was found for duration until full RTW. Treatment response of common mental disorder symptoms did not differ significantly between the groups, but at 9 months after baseline significantly more participants in the ECO group achieved remission than in the CAU group (OR 2.228, 95% CI 1.115-4.453, P=.02).

Conclusions

The results of this study showed that in a group of sick-listed employees with common mental disorders, applying the blended eHealth ECO intervention led to faster first RTW and more remission of common mental disorder symptoms than CAU.

Longitudinal changes in drug use severity and physical health-related quality of life among untreated stimulant users

The primary objective of this study was to investigate whether drug use severity is associated with physical health-related quality of life (HRQL) over time. Data are from a longitudinal, multi-state, natural history community study of users of cocaine and/or methamphetamine who were interviewed at 6-month intervals over 2 years with a 79% follow-up participation rate. Physical HRQL was assessed with the physical component summary (PCS) of the SF-8™ Health Survey and drug, alcohol, and psychiatric severity were all assessed with the Addiction Severity Index (ASI). Random coefficient regression analyses were conducted to test for longitudinal associations between the independent variables and SF-8 PCS scores. Reductions in drug use severity over time were accompanied by only minor improvements in SF-8 PCS scores, underscoring the potential long-term harm of illicit drug use on physical health. Greater psychiatric severity was strongly associated with lower SF-8 PCS scores, suggesting that clinical attention to mental health issues could potentially lead to improvements in perceived physical health as well as among stimulant users.
