Having a good relationship with their mother: a protective factor against sexual risk behavior among adolescent females?

STUDY OBJECTIVE: To assess whether having a good relationship with their mother was a protective factor against risky sexual behavior for female adolescents and whether it was independent of family structure. DESIGN: Cross-sectional survey of in-school adolescents aged 14-19 years. SETTING: Catalonia, in northeast Spain. PARTICIPANTS: A total of 3677 females divided according on whether they had a good (n=3335) or a bad (n=342) relationship with their mother. MAIN OUTCOME MEASURES: Rates of sexual activity and sexual behavior. RESULTS: Adolescents in the good relationship group were significantly younger, more likely to live in an intact family, to have a good relationship with their father and siblings, and to talk about sexuality and their partner with their mother. They were also less likely to have ever had sexual intercourse. Among those sexually experienced, they were significantly older at first intercourse and less likely to have multiple partners or a history of STI. After adjusting for potential confounders, females in the good relationship group were less likely to be sexually active and to have had multiple partners, independently of family structure. CONCLUSIONS: Having a good relationship with their mother is a protective factor against sexual intercourse and having multiple sexual partners independently of family structure. Communication between generations and having a good relationship with their father and siblings also play an important role.

Diagnosis of Birt-Hogg-Dube syndrome in a patient with spontaneous pneumothorax

Birt-Hogg-Dube syndrome refers to a dermatologic syndrome, consisting of small papular skins lesion distributed on the scalp, forehead, face and neck, which is autosomal dominantly inherited. Subsequently patients may develop concomitant renal and thoracic pathology. We report the case of a patient with Birt-Hogg-Dube syndrome diagnosed after spontaneous pneumothorax.

Brief alcohol intervention and alcohol assessment do not influence alcohol use in injured patients treated in the emergency department: a randomized controlled clinical trial.

AIMS: To evaluate the effectiveness of brief alcohol intervention (BAI) in reducing alcohol use among hazardous drinkers treated in the emergency department (ED) after an injury; in addition it tests whether assessment of alcohol use without BAI is sufficient to reduce hazardous drinking. DESIGN: Randomized controlled clinical trial with 12-month follow-up conducted between January 2003 and June 2005. SETTING: Urban academic emergency department (ED) of the Lausanne University Hospital, Lausanne, Switzerland. PARTICIPANTS: A total of 5136 consecutive patients attending ED after an injury completed a seven-item general and a three-item alcohol screen and 1472 (28.7%) were positive for hazardous drinking according to the National Institute on Alcohol Abuse and Addiction definition; of these 987 (67.1%) were randomized into a BAI group (n = 310) or a control group with screening and assessment (n = 342) or a control group with screening only (n = 335) and then a total of 770 patients (78.0%) completed the 12-month follow-up procedures. INTERVENTION: A single 10-15-minute session of standardized BAI conducted by a trained research assistant. MEASUREMENTS: Percentage of participants who have changed to low-risk drinking at follow-up. FINDINGS: Data obtained at 12 months indicated that similar proportions were low-risk drinkers in BAI versus control groups with and without assessment (35.6%, 34.0%, 37.0%, respectively, P = 0.71). Data also indicated similar reductions in drinking frequency, quantity, binge drinking frequency and Alcohol Use Disorders Identification Test (AUDIT) scores across groups. All groups reported similar numbers of days hospitalized and numbers of medical consults in the last 12 months. A model including age groups, gender, AUDIT and injury severity scores indicated that BAI had no influence on the main alcohol use outcome. CONCLUSIONS: This study provides the evidence that a 10-15-minute BAI does not decrease alcohol use and health resource utilization in hazardous drinkers treated in the ED, and demonstrates that commonly found decreases in hazardous alcohol use in control groups cannot be attributed to the baseline alcohol assessment.

Frequency of severe pulmonary hypertension complicating "isolated" atrial septal defect in infancy.

Atrial septal defects (ASDs) are typically asymptomatic in infancy and early childhood, and elective defect closure is usually performed at ages of 4 to 6 years. Severe pulmonary hypertension (PH) complicating an ASD is seen in adulthood and has only occasionally been reported in small children. A retrospective study was undertaken to evaluate the incidence of severe PH complicating an isolated ASD and requiring early surgical correction. During a 10-year period (1996 to 2006), 355 pediatric patients underwent treatment for isolated ASDs either surgically or by catheter intervention at 2 tertiary referral centers. Two hundred ninety-seven patients had secundum ASDs, and 58 had primum ASDs with mild to moderate mitral regurgitation. Eight infants were found with isolated ASDs (6 with secundum ASDs and 2 with primum ASDs) associated with significant PH, accounting for 2.2% of all patients with ASDs at the centers. These 8 infants had invasively measured pulmonary artery pressures of 50% to 100% of systemic pressure. They were operated in the first year of life and had complicated postoperative courses requiring specific treatment for PH for up to 16 weeks postoperatively. The ultimate outcomes in all 8 infants were good, with persistent normalization of pulmonary pressures during midterm follow-up of up to 60 months (median 28). All other patients with ASDs had normal pulmonary pressures, and the mean age at defect closure was significantly older, at 6.2 years for secundum ASDs and 3.2 years for primum ASDs. In conclusion, ASDs were rarely associated with significant PH in infancy but then required early surgery and were associated with excellent midterm outcomes in these patients.

New diagnoses of dementia among older patients admitted to postacute care.

Objectives: To determine the prevalence of dementia and the proportion of undiagnosed dementia in elderly patients admitted to postacute care, and to identify patients' characteristics associated with undiagnosed dementia. Design: Cross-sectional study. Setting: Academic postacute rehabilitation facility in Lausanne, Switzerland. Participants: Patients (N = 1764) aged 70 years and older. Measurements: Data on socio-demographic, medical, functional, and affective status were collected upon admission. Data on cognitive performance (Mini-Mental State Exam [MMSE]), and cognition-related discharge diagnoses were abstracted through a structured review of discharge summaries. Results: Overall, 24.1% (425/1764) patients had a diagnosis of dementia, most frequently secondary to Alzheimer's disease (260/425, 61.2%). Among dementia cases, 70.8% (301/425) were newly diagnosed during postacute stay. This proportion was lower among patients referred from internal medicine than from orthopedic/surgery services (65.8% versus 74.8%, P = .042). Compared to patients with already diagnosed dementia, those newly diagnosed were older, lived alone more frequently, and had better functional status and MMSE score at admission (all P < .05). In multivariate analysis, previously undetected dementia remained associated with older age (OR = 2.4 for age 85 years and older, 95% CI 1.5-4.0, P = .001) and normal MMSE at admission (OR = 5.9, 95% CI 2.7-12.7, P < .001). Conclusion: Dementia was present in almost a fourth of elderly patients referred to postacute care, but was diagnosed in less than a third before admission. Oldest old patients appear especially at risk for underrecognition. These results emphasize the high diagnostic yield of systematic cognitive assessment in the postacute care setting to improve these patients' management and quality of life.

Temozolomide versus standard 6-week radiotherapy versus hypofractionated radiotherapy in patients older than 60 years with glioblastoma: the Nordic randomised, phase 3 trial.

BACKGROUND: Most patients with glioblastoma are older than 60 years, but treatment guidelines are based on trials in patients aged only up to 70 years. We did a randomised trial to assess the optimum palliative treatment in patients aged 60 years and older with glioblastoma. METHODS: Patients with newly diagnosed glioblastoma were recruited from Austria, Denmark, France, Norway, Sweden, Switzerland, and Turkey. They were assigned by a computer-generated randomisation schedule, stratified by centre, to receive temozolomide (200 mg/m(2) on days 1-5 of every 28 days for up to six cycles), hypofractionated radiotherapy (34·0 Gy administered in 3·4 Gy fractions over 2 weeks), or standard radiotherapy (60·0 Gy administered in 2·0 Gy fractions over 6 weeks). Patients and study staff were aware of treatment assignment. The primary endpoint was overall survival. Analyses were done by intention to treat. This trial is registered, number ISRCTN81470623. FINDINGS: 342 patients were enrolled, of whom 291 were randomised across three treatment groups (temozolomide n=93, hypofractionated radiotherapy n=98, standard radiotherapy n=100) and 51 of whom were randomised across only two groups (temozolomide n=26, hypofractionated radiotherapy n=25). In the three-group randomisation, in comparison with standard radiotherapy, median overall survival was significantly longer with temozolomide (8·3 months [95% CI 7·1-9·5; n=93] vs 6·0 months [95% CI 5·1-6·8; n=100], hazard ratio [HR] 0·70; 95% CI 0·52-0·93, p=0·01), but not with hypofractionated radiotherapy (7·5 months [6·5-8·6; n=98], HR 0·85 [0·64-1·12], p=0·24). For all patients who received temozolomide or hypofractionated radiotherapy (n=242) overall survival was similar (8·4 months [7·3-9·4; n=119] vs 7·4 months [6·4-8·4; n=123]; HR 0·82, 95% CI 0·63-1·06; p=0·12). For age older than 70 years, survival was better with temozolomide and with hypofractionated radiotherapy than with standard radiotherapy (HR for temozolomide vs standard radiotherapy 0·35 [0·21-0·56], p<0·0001; HR for hypofractionated vs standard radiotherapy 0·59 [95% CI 0·37-0·93], p=0·02). Patients treated with temozolomide who had tumour MGMT promoter methylation had significantly longer survival than those without MGMT promoter methylation (9·7 months [95% CI 8·0-11·4] vs 6·8 months [5·9-7·7]; HR 0·56 [95% CI 0·34-0·93], p=0·02), but no difference was noted between those with methylated and unmethylated MGMT promoter treated with radiotherapy (HR 0·97 [95% CI 0·69-1·38]; p=0·81). As expected, the most common grade 3-4 adverse events in the temozolomide group were neutropenia (n=12) and thrombocytopenia (n=18). Grade 3-5 infections in all randomisation groups were reported in 18 patients. Two patients had fatal infections (one in the temozolomide group and one in the standard radiotherapy group) and one in the temozolomide group with grade 2 thrombocytopenia died from complications after surgery for a gastrointestinal bleed. INTERPRETATION: Standard radiotherapy was associated with poor outcomes, especially in patients older than 70 years. Both temozolomide and hypofractionated radiotherapy should be considered as standard treatment options in elderly patients with glioblastoma. MGMT promoter methylation status might be a useful predictive marker for benefit from temozolomide.

Justice et criminalité (Vaud, XVe-XXIe siècles)

A la veille de l'introduction de la réforme pénale et civile fédérale dans le canton de Vaud en 2011, la Revue historique vaudoise s'est intéressée à l'histoire de la justice et de la criminalité. Le présent numéro réunit des contributions d'historiens, historiens du droit et historiens de l'art, jeunes ou confirmés, qui livrent ici les résultats de leurs recherches en cours ou récentes, ainsi que des témoignages de magistrats sur l'exercice de la justice et sur les conséquences des changements à venir. Pour cette thématique qui est un champ dynamique de la recherche historiques en Suisse et en Europe depuis la fin des années 1970, deux axes principaux ont été privilégies pour interroger l'exercice de la justice et les interactions entre l'Etat et les justiciables. Le premier traite de la figure du criminel et de la représentation du crime par un examen des pratiques et des discours judiciaires. Le second se concentre sur les acteurs de la justice et sur leurs modes d'actions et leurs motivations. En privilégiant un traitement sur la longue durée, du Moyen Âge à nos jours, ainsi que des études de cas, ce dossier thématique propose des éclairages successifs sur la justice et la criminalité en terres vaudoises. Ils mettent en évidence des transitions, des ruptures et des innovations révélatrices des institutions, de leur fonctionnement et du rôle social de leurs agents

Glioblastoma in elderly patients: health-related quality of life (hrqol) in a randomized trial comparing 6-weeks of tadiotherapy (rt) vs hypofractionated rt over 2 weeks vs temozolomide chemotherapy (tmz)

BACKGROUND: Despite advances in treatment, survival of patients with GBM over 60 years is still often less than 1 year. In the perspective of a short expected survival, the quality of the remaining life and the effects of therapy on health-related quality of life (HRQoL) should be given special emphasis when recommending treatment for the individual patients. Several studies have focused on survival of the elderly, but few data are available on HRQoL for different treatments. In a randomized trial, we compared survival and HRQoL for 3 treatment options, 6 weeks of RT, vs hypofractionated RT, or chemotherapy with TMZ. MATERIALS AND METHODS: Newly diagnosed GBM patients, age ≥60 years with PS 0-2, were randomized to either standard RT (60 Gy in 2-Gy fractions over 6 weeks), hypofractionated RT (34 Gy in 3.4-Gy fractions over 2 weeks), or 6 cycles of chemotherapy with TMZ (200 mg/m2 day 1-5 every 28 days). QoL was determined by the EORTC QLQ 30 questionnaire and the Brain Cancer Module at inclusion, before start of therapy, at 6 weeks, 3 months, and 6 months after start of treatment. Patients were followed until death. The primary study endpoint was overall survival (OS) and secondary objectives were HRQoL, neurologic symptom control, and safety. RESULTS: A total of 342 patients were included and 292 patients were randomized between the 3 treatment options and 50 patients between hypofractionated RT and TMZ. Median age was 70 years (range 60-92) with 58% being male. Performance status was 0-1 for 75% of patients and 73% had undergone surgical resection. CONCLUSION: The results from the HRQoL analysis of this trial will be presented together with survival data at the upcoming EANO meeting.

Plunging when drilling: effect of using blunt drill bits.

OBJECTIVE: : Plunging when drilling can be a detrimental factor in patient care. There is, although, a general lack of information regarding the surgeon's performance in this skill. The aim of this study was to determine the effect that using sharp or blunt instruments had on the drill bit's soft tissue penetration, using a simulator. MATERIALS AND METHODS: : Surgeons taking part in an International Trauma Course were invited to participate. Two groups were defined: experienced and inexperienced surgeons. Twelve holes were drilled in the following order: 3 holes with a sharp drill bit in normal bone (SNB), 3 holes with a sharp drill bit in osteoporotic bone (SOB), 3 holes with a blunt drill bit in normal bone, and 3 holes with a blunt drill bit in osteoporotic bone. Mean values and Student t tests were used for statistical analysis. RESULTS: : Thirty-seven surgeons participated, 20 experienced and 17 inexperienced surgeons. Mean plunging depths for SNB, SOB, blunt drill bit in normal bone, and blunt drill bit in osteoporotic bone were, respectively, 5.1, 5.4, 21.1, and 13.9 mm for experienced surgeons and 7.6, 7.7, 22, and 15.9 mm for inexperienced surgeons. Drilling with SNB and with SOB was statistically different, with inexperienced surgeons plunging 2.5 mm (P = 0.31) and 2.6 mm (P = 0.042) deeper, respectively. There was a difference (P < 0.001) between sharp and blunt drill bits in all drilling conditions for both the groups. CONCLUSIONS: : Our study showed a significant difference in plunging depth when sharp or bunt drill bit was being used. Surgeons, regardless of their experience level, penetrate over 20 mm in normal bone and over 10 mm in osteoporotic bone.

Gene transfer of a soluble IL-1 type 2 receptor-Ig fusion protein improves cardiac allograft survival in rats.

OBJECTIVE: Interleukin-1 (IL-1) mediates ischemia-reperfusion injury and graft inflammation after heart transplantation. IL-1 affects target cells through two distinct types of transmembrane receptors, type-1 receptor (IL-1R1), which transduces the signal, and the non-signaling type-2 receptor (IL-1R2), which acts as a ligand sink that subtracts IL-1beta from IL-1R1. We analyzed the efficacy of adenovirus (Ad)-mediated gene transfer of a soluble IL-1R2-Ig fusion protein in delaying cardiac allograft rejection and the mechanisms underlying the protective effect. METHODS: IL-1 inhibition by IL-1R2-Ig was tested using an in vitro functional assay whereby endothelial cells preincubated with AdIL-1R2-Ig or control virus were stimulated with recombinant IL-1beta or tumor necrosis factor-alpha (TNF-alpha), and urokinase-type plasminogen activator (u-PA) induction was measured by zymography. AdIL-1R2-Ig was delivered to F344 rat donor hearts ex vivo, which were placed in the abdominal position in LEW hosts. Intragraft inflammatory cell infiltrates and proinflammatory cytokine expression were analyzed by immunohistochemistry and real-time reverse transcriptase-polymerase chain reaction (RT-PCR), respectively. RESULTS: IL-1R2-Ig specifically inhibited IL-1beta-induced u-PA responses in vitro. IL-1R2-Ig gene transfer reduced intragraft monocytes/macrophages and CD4(+) cell infiltrates (p<0.05), TNF-alpha and transforming growth factor-beta (TGF-beta) expression (p<0.05), and prolonged graft survival (15.6+/-5.7 vs 10.3+/-2.5 days with control vector and 10.1+/-2.1 days with buffer alone; p<0.01). AdIL-1R2-Ig combined with a subtherapeutic regimen of cyclosporin A (CsA) was superior to CsA alone (19.4+/-3.0 vs 15.9+/-1.8 days; p<0.05). CONCLUSIONS: Soluble IL-1 type-2 receptor gene transfer attenuates cardiac allograft rejection in a rat model. IL-1 inhibition may be useful as an adjuvant therapy in heart transplantation.

Différences induites par la définition des périodes diurnes et nocturnes sur la pression artérielle et le dipping lors d'une mesure ambulatoire de la pression artérielle [Effects of nighttime and daytime interval definition on blood pressure and dipping in patients referred for ambulatory blood pressure measurement].

Ambulatory blood pressure monitoring (ABPM) has become indispensable for the diagnosis and control of hypertension. However, no consensus exists on how daytime and nighttime periods should be defined. OBJECTIVE: To compare daytime and nighttime blood pressure (BP) defined by an actigraph and by body position with BP resulting from arbitrary daytime and nighttime periods. PATIENTS AND METHOD: ABPM, sleeping periods and body position were recorded simultaneously using an actigraph (SenseWear Armband(®)) in patients referred for ABPM. BP results obtained with the actigraph (sleep and position) were compared to the results obtained with fixed daytime (7a.m.-10p.m.) and nighttime (10p.m.-7a.m.) periods. RESULTS: Data from 103 participants were available. More than half of them were taking antihypertensive drugs. Nocturnal BP was lower (systolic BP: 2.08±4.50mmHg; diastolic BP: 1.84±2.99mmHg, P<0.05) and dipping was more marked (systolic BP: 1.54±3.76%; diastolic BP: 2.27±3.48%, P<0.05) when nighttime was defined with the actigraph. Standing BP was higher (systolic BP 1.07±2.81mmHg; diastolic BP: 1.34±2.50mmHg) than daytime BP defined by a fixed period. CONCLUSION: Diurnal BP, nocturnal BP and dipping are influenced by the definition of daytime and nighttime periods. Studies evaluating the prognostic value of each method are needed to clarify which definition should be used.

Real-time quantitative PCR assay for measurement of bird telomeres

We present the application of a real-time quantitative PCR assay, previously developed to measure relative telomere length in humans and mice, to two bird species, the zebra finch Taeniopygia guttata and the Alpine swift Apus melba. This technique is based on the PCR amplification of telomeric (TTAGGG)(n) sequences using specific oligonucleotide primers. Relative telomere length is expressed as the ratio (T/S) of telomere repeat copy number (T) to control single gene copy number (S). This method is particularly useful for comparisons of individuals within species, or where the same individuals are followed longitudinally. We used glyceraldehyde-3-phosphate dehydrogenase (GAPDH) as a single control gene. In both species, we validated our PCR measurements of relative telomere length against absolute measurements of telomere length determined by the conventional method of quantifying telomere terminal restriction fragment (TRF) lengths using both the traditional Southern blot analysis (Alpine swifts) and in gel hybridization (zebra finches). As found in humans and mice, telomere lengths in the same sample measured by TRF and PCR were well correlated in both the Alpine swift and the zebra finch.. Hence, this PCR assay for measurement of bird telomeres, which is fast and requires only small amounts of genomic DNA, should open new avenues in the study of environmental factors influencing variation in telomere length, and how this variation translates into variation in cellular and whole organism senescence.
