Risks and Benefits of Adolescent Girls’ Participation in Online Sexting Survey Research

The increasingly ubiquitous use of sexting among adolescent girls underscores the importance of empirical data on their sexting behaviors, motivations, and outcomes. To date, the majority of sexting studies have been conducted online; however, little is known about the extent to which responding to such socially sensitive questions may cause participant discomfort or distress. Research on this question is critical since in the absence of empirical data, institutional review boards (IRBs) may permit or place restrictions on online sexting studies based on an under- or overestimation of adolescent participation risk. The current online study asked 210 girls (aged 14–18 years, 55% non-Hispanic White, with sexting experience in the past 12 months) who previously registered to take online surveys on (1) their anticipated comfort in responding to a sexting survey include items on sexting motivations, positive and negative sexting consequences, and related sexual behaviors; (2) their perceptions of sexting research benefits/harms; and (3) comfort discussing similar topics in everyday life and with health professionals. Overall, participants were comfortable responding to sexting survey questions, rated sexting research as high benefits and low risks, and felt about the same as or more comfortable completing a sexting survey than discussing similar topics with peers, parents, or healthcare professionals. Findings suggest that anonymous online sexting studies can be classified as minimal risk research for adolescent girls and provide empirical support for IRB decisions to waive guardian permission for participation in such studies.

     

Word-finding difficulties in French-speaking children with SLI: a case STUDY

This study presents the case of a 9-year-old boy, Jeoffrey, with word-finding difficulties. In an attempt to investigate the cause(s) of these difficulties, an in-depth evaluation of his semantic and phonological skills was carried out, in which lexical and phonological variables such as age of acquisition or phonological complexity were controlled. Jeoffrey's performance was compared to a child matched for age. Although Jeoffrey showed no apparent phonological deficit, our results revealed deficits in semantic processes. We argue that this boy's word-finding difficulties are the result of imprecise and unspecified semantic representations. Therefore, as this case demonstrates, it is essential to determine the origin(s) of children's word-finding difficulties, which could be different and specific for each child presenting such a lexical deficit.     

Action of sublingual nifedipine on left ventricular filling in hypertensive crisis

We studied the left ventricular filling before and 15 minutes after sublingual absorption of one Nifedipine capsule in 33 untreated hypertensive patients (mean age: 68.6) without other cardiac disease and presenting an hypertensive access. This study was carried out with Doppler-echocardiography. Sample volume was set at the tips of mitral leaflets. The protocol included: early peak filling velocity (VE), atrial peak velocity (VA), mitral pressure half-time (T1/2), isovolumic relaxation time (TRIV), velocity time integral of total mitral curve (VTIT) and velocity time integral of atrial curve (VTIA). We also studied VE/VTIT ratio which has been correlated to peak filling rate/mitral stroke volume ratio in radionuclide angiography. RESULTS: [table: see text] The variations of VA/VE, VTIA/VTIT, VE/VTIT and T1/2 are statistically significant but decrease of TRIV is not significant. The arterial blood pressure decreases from 184/103 to 153/83 and cardiac rate increases from 81.8 to 87.9 beats/minute. CONCLUSION: On hypertensive emergencies sublingual nifedipine significantly improves rapid left ventricular filling without change of TRIV. Acceleration of cardiac rate is moderate.     

A HYPNOSIS-BASED GROUP INTERVENTION TO IMPROVE QUALITY OF LIFE IN CHILDREN WITH CANCER AND THEIR PARENTS

Many children with cancer and their parents suffer from distress, fatigue, and relational difficulties. Hypnosis is often used to decrease children’s procedure-related pain and distress in pediatric oncology and to improve the well-being of adults with cancer. This article describes a pilot study assessing the acceptability and feasibility of a group intervention combining self-care and hypnosis for children with cancer and their parents, and a quasi-experimental protocol aimed at assessing the efficacy of this intervention to improve quality of life, distress, fatigue, and coping. The pilot study showed that the intervention was feasible and perceived positively. Future research is needed to test the efficacy of group interventions combining self-care and hypnosis to improve quality of life for children with cancer and their families.     

Iranian beet necrotic yellow vein virus (BNYVV): pronounced diversity of the p25 coding region in A-type BNYVV and identification of P-type BNYVV lacking a fifth RNA species

Beet necrotic yellow vein virus (BNYVV) was detected in 288 of the 392 samples collected in Iran. A-type BNYVV was detected most frequently. The p25 coding region on BNYVV RNA-3 was amplified by RT-PCR and sequenced. Nine different variants of the highly variable amino acid tetrad at positions 67–70 of p25 were identified, i.e. ACHG, AHHG, AYHG, ALHG, AFHR, AFHG, AHYG, VLHG and VHHG. These are more different tetrad variants than have been reported from any other country. The first three variants were found most commonly. In 23 out of the 288 BNYVV-positive samples, we detected P-type BNYVV that had previously been identified only in France, Kazakhstan and recently in the UK. Surprisingly, none of these samples contained the fifth RNA species usually associated with P-type BNYVV in other countries. As in other BNYVV P-type sources, the p25 amino acid tetrad in positions 67–70 of the Iranian P-type consists of SYHG.

Comparison of the beet necrotic yellow vein virus P75 nucleotide sequences of Belgian type A and type B sources

RNA-2 P75 open reading frame sequencing was conducted on BNYVV-infected sugar beet plants originating from 10 Belgian sources and was compared with sequences originating from France, Kazakhstan, Japan and China. This allowed the characterization of types A and B in Belgium. Sequence analysis confirmed that type A is intermediate between types P and B. The analysis of nucleotide sequences of the capsid protein epitopes and of different motifs involved in the transmission of the virus to the plant by Polymyxa betae reveals that they are well conserved among the different sequences analysed. In silico analysis showed that a potential dimerization/dsRNA-binding domain is present on P75. Finally, in order to compare the different BNYVV types, a real-time quantitative (RT)-PCR targeting the readthrough domain of P75 was developed and assessed over a period of 40 days on BNYVV susceptible sugar beet cv. Cadyx.     

Apprentissage de l’autohypnose/autobienveillance en oncologie. Pour qui ? Comment ? Dans quel intérêt ? Une revue de la littérature internationale

The most common physical symptoms related to cancer and its treatments are pain, nausea and fatigue. They can negatively affect the quality of life in general. Group interventions teaching self-hypnosis, with or without selfcare, have been found to improve the adaptation of oncology patients. The aim of this review is to highlight the effectiveness of hypnosis in the management of symptoms related to the disease and to better understand its mechanisms.
