Méta-analyses d'essais randomisés sur données individuelles dans le traitement des cancers ORL non métastatiques : principes, résultats, perspectives [Individual patient data meta-analyses of randomized trials for the treatment of non-metastatic head and neck squamous cell carcinomas: Principles, results and perspectives].

Meta-analyses are considered as an important pillar of evidence-based medicine. The aim of this review is to describe the main principles of a meta-analysis and to use examples of head and neck oncology to demonstrate their clinical impact and methodological interest. The major role of individual patient data is outlined, as well as the superiority of individual patient data over meta-analyses based on published summary data. The major clinical breakthrough of head and neck meta-analyses are summarized, regarding concomitant chemotherapy, altered fractionated chemotherapy, new regimens of induction chemotherapy or the use of radioprotectants. Recent methodological developments are described, including network meta-analyses, the validation of surrogate markers. Lastly, the future of meta-analyses is discussed in the context of personalized medicine.

Present standards and future perspectives in the treatment of metastatic non-small cell lung cancer.

The development of novel effective immunotherapeutic agents and early clinical data hinting at significant activity in non-small cell lung cancer (NSCLC) has introduced yet another player in the field of management of advanced disease. At present, first-line cytotoxic chemotherapy is generally withheld pending results of molecular testing for any actionable genetic alteration that could lead to targeted treatment, and in their absence chemotherapy is prescribed as a default therapy. Phase III trials comparing head-to-head immune checkpoint inhibitors with standard platinum-based doublet chemotherapy are underway. Second-line chemotherapy is likewise being challenged in phase III trials, one of which having recently reported positive results in advanced squamous cell carcinoma. In tumors harboring actionable transforming genetic alterations such as EGFR mutations and ALK rearrangements, second- and third-generation inhibitors allow for multiple lines of targeted treatment beyond initial resistance, postponing the use of cytotoxic chemotherapy to very late lines of therapy. Chemotherapy as a longstanding but still present standard of care capable of prolonging survival, improving quality of life, and relieving symptoms sees its role increasingly restricted to clinical, immunological, and molecular subsets of patients where its activity and efficacy have never been tested prospectively.

Patients' satisfaction with community treatment: a pilot cross-sectional survey adopting multiple perspectives.

ACCESSIBLE SUMMARY: Patients' satisfaction is scarcely studied within the context of community treatment for adolescents. Thus, this study adopts a multiple perspective on patients' satisfaction (including service users as well as staff members). The results highlighted that all informants (patients, foster carers in foster homes and professional caregivers from community treatment teams) perceived the patients to be satisfied, with foster carers reporting the highest patient satisfaction rate. Considering the patient satisfaction rate from multiple perspectives provides complementary understandings. Clinical outcomes and, specifically, a reduction in emotional difficulties were related to patient's satisfaction, but only from the patients' perspective. ABSTRACT: Community treatment (CT) teams in Switzerland provide care to patients who are unable to use regular child and adolescent mental health services (i.e. inpatient and outpatients facilities). No study has considered patients' self-rated satisfaction alongside with staff members' perspectives on patient satisfaction. Thus, adopting a cross-sectional survey design, we collected patients' satisfaction using the Client Satisfaction Questionnaire (CSQ-8), rated by multiple informants (patients, foster carers in foster homes and professional caregivers from CT teams). Professional caregivers assessed clinical outcomes using the Health of the Nation Outcome Scale for Children and Adolescents. The results indicated that all informants were satisfied with the community treatment teams. The satisfaction scores were not correlated across informants; however, the alleviation of emotional symptoms was correlated with patients' satisfaction. This study indicated that the use of a combined approach including the views of service users and professionals gives important complementary information. Finally, in our sample, lower emotional symptoms were linked to enhanced patient satisfaction. This study demonstrated the importance of considering multiple perspectives to obtain the most accurate picture of patients' satisfaction. Second, focusing on the reduction of emotional symptoms might lead to a higher degree of patients' satisfaction.

Multigene Family Evolution: Perspectives from Insect Chemoreceptors.

Understanding the birth and diversification of multigene families is a fundamental evolutionary problem. I argue for the insect chemoreceptor superfamily as an outstanding model. Although these receptors are currently the preserve of neuroscientists, putative homologous genes exist in diverse animal and plant genomes, implying an ancient origin. Moreover, functional studies suggest that they act as ligand-gated ion channels in both chemosensory and non-chemosensory processes. This family permits synergism of investigations into its structural and regulatory evolution with ecological studies of the selective pressures driving these changes. In addition, sequence divergence in these receptors can be exploited through co-evolutionary and comparative genomics analyses to help to elucidate their 3D structure and signaling mechanisms, and to reveal experimentally-accessible candidate loci to explore the genetic basis of adaptation.

Quelles questions émergentes pour les politiques publiques de biodiversité en France métropolitaine? Résultats et perspectives

Dans un contexte en constante évolution, l'élaboration, la mise en oeuvre et l'évaluation des politiques publiques de biodiversité nécessitent d'anticiper les changements futurs possibles afin de pouvoir se préparer à temps. Or les informations concernant ces changements sont nombreuses et les enjeux qui pourraient s'avérer importants à l'avenir sont souvent peu visibles. Pour répondre à ce défi, une expertise multi-acteurs et multidisciplinaire s'inspirant des démarches d'horizon scanning et intitulée BioPIQue 2013 a permis d'identifier 25 questions émergentes, dont 10 questions stratégiques, pour les politiques publiques de biodiversité en France métropolitaine d'ici à 2020. Ces questions émergentes sont autant d'opportunités et de risques que l'ensemble es acteurs qui souhaitent avancer vers une plus grande prise en compte des enjeux de biodiversité peuvent saisir.
