Recommendations for Method Development and Validation of qPCR and dPCR Assays in Support of Cell and Gene Therapy Drug Development

The emerging use of qPCR and dPCR in regulated bioanalysis and absence of regulatory guidance on assay validations for these platforms has resulted in discussions on lack of harmonization on assay design and appropriate acceptance criteria for these assays. Both qPCR and dPCR are extensively used to answer bioanalytical questions for novel modalities such as cell and gene therapies. Following cross-industry conversations on the lack of information and guidelines for these assays, an American Association of Pharmaceutical Scientists working group was formed to address these gaps by bringing together 37 industry experts from 24 organizations to discuss best practices to gain a better understanding in the industry and facilitate filings to health authorities. Herein, this team provides considerations on assay design, development, and validation testing for PCR assays that are used in cell and gene therapies including (1) biodistribution; (2) transgene expression; (3) viral shedding; (4) and persistence or cellular kinetics of cell therapies.

Pelvic floor muscle rehabilitation for genitourinary syndrome of menopause: why, how and when?

Genitourinary syndrome of menopause (GSM) is caused by chronic deprivation of estrogen and other sex steroids during the postmenopausal period, which leads to changes in the vulvovaginal tissues. These changes cause bothersome symptoms, such as vaginal dryness, pruritus, dyspareunia, increased daytime urinary frequency, urgency and urinary incontinence, which have considerable negative effects on women's quality of life and sexual function. Recent studies have investigated a novel treatment approach for GSM. Pelvic floor muscle (PFM) rehabilitation, a low-cost conservative management with no side-effects, has been studied alone or in combination with other treatment modalities to reduce the signs and symptoms of GSM. The aim of this article is to discuss why PFM rehabilitation could be useful for women with GSM, how it may help improve signs and symptoms of GSM and when this treatment should be recommended.

The role of SR protein kinases in regulating lipid storage in the Drosophila fat body

The survival of animals during periods of limited nutrients is dependent on the organism's ability to store lipids during times of nutrient abundance. However, the increased availability of food in modern western society has led to an excess storage of lipids resulting in metabolic diseases. To better understand the genes involved in regulating lipid storage, genome-wide RNAi screens were performed in cultured Drosophila cells and one group of genes identified includes mRNA splicing factor genes. Our lab has previously shown that a group of splicing factors important for intron/exon border recognition known as SR proteins are involved in controlling lipid storage in Drosophila; however, how these SR proteins are regulated to control lipid storage is not fully understood. Here, we focus on two SR protein kinases (SRPKs) in Drosophila: SRPK and SRPK79D. Decreasing the expression of these genes specifically in the adult fat body using RNAi resulted in lower levels of triglycerides and this is due to a decrease in the amount of fat stored per cell, despite having more fat cells, when compared to control flies. Decreasing SRPK and SRPK79D levels in the fat body leads to altered splicing of the β-oxidation gene, carnitine palmitoyltransferase 1 (CPT1), resulting in increased production of a more active enzyme, which would increase lipid breakdown and be consistent with the lean phenotype observed in these flies. In addition, flies with decreased SRPK and SRPK79D levels in their fat bodies eat less, which may also contribute to the decreased triglyceride phenotype. Together, these findings provide evidence to support that lipid storage is controlled by the phosphorylation of factors involved in mRNA splicing.

Sarcoidosis diagnosed in the elderly: a case-control study

BACKGROUND

Studies on sarcoidosis in elderly patients are scarce and none have specifically evaluated patients aged ≥75 at onset.

AIM

We aimed to analyse the characteristics of patients with sarcoidosis diagnosed after 75 and to compare them with those of younger patients.

DESIGN

Multicenter case-control study comparing elderly-onset sarcoidosis (EOS) with young-onset sarcoidosis (YOS) seen at Lyon University Hospitals between 2006 and 2018.

METHODS

Using our institutional database, we included 34 patients in the EOS group and compared them with 102 controls from the YOS group in a 1:3 ratio. Demographic characteristics, medical history, clinical presentation, laboratory and imaging findings, sites of biopsies, histological analyses, treatments and outcomes were recorded using a comprehensive questionnaire.

RESULTS

There were more Caucasians in the EOS group (94.1% vs. 59.8%; P < 0.001), who had significantly more comorbidities (mean, 3.1 ± 2 vs. 1.1 ± 1.6; P < 0.001). In the EOS group, there was less pulmonary involvement (26.5% vs. 49%; P = 0.022), less lymphadenopathy (2.9% vs. 16.7%; P = 0.041), no erythema nodosum (0% vs. 12.8%; P = 0.029) and no arthralgia (0% vs. 25.5%; P = 0.001). Conversely, uveitis was more common in the EOS group (55.9% vs. 20.6%; P < 0.001). Pathological confirmation was obtained significantly less frequently in the EOS group (67.7% vs. 85.3%; P = 0.023). Corticosteroid-related side effects were significantly more common in the EOS group (100% vs. 75.9%; P = 0.030).

CONCLUSION

Epidemiology and clinical presentation of EOS differs from YOS, including more comorbidities and more uveitis. Elderly patients are more prone to corticosteroid side effects.

Gene Therapy: A Possible Alternative to CFTR Modulators?

Cystic fibrosis (CF) is a rare genetic disease that affects several organs, but lung disease is the major cause of morbidity and mortality. The gene responsible for CF, the CFTR (Cystic Fibrosis Transmembrane Conductance Regulator) gene, has been discovered in 1989. Since then, gene therapy i.e., defective gene replacement by a functional one, remained the ultimate goal but unfortunately, it has not yet been achieved. However, patients care and symptomatic treatments considerably increased CF patients’ life expectancy ranging from 5 years old in the 1960s to 40 today. In the last decade, research works on CFTR protein structure and activity led to the development of new drugs which, by readdressing CFTR to the plasma membrane (correctors) or by enhancing its transport activity (potentiators), allow, alone or in combination, an improvement of CF patients’ lung function and quality of life. While expected, it is not yet known whether taking these drugs from an early age and for years will improve the quality of life of CF patients in the long term and further increase their life expectancy. Besides, these molecules are not available (specific variants of CFTR) or accessible (national health policies) for all patients and there is still no curative treatment. Another alternative that could benefit from new technologies, such as gene therapy, is therefore still attractive, although it is not yet offered to patients. Faced with the development of new CFTR correctors and potentiators, the question arises as to whether there is still a place for gene therapy and this is discussed in this perspective.

Inventaire des cognitions à risque — Loteries sportives (ICR-LS) : un premier pas dans l’élaboration de mesures spécifiques au type de jeu/The Inventaire des cognitions à risque Loteries Sportives: A First Step in Developing Game-Specific Measures

À travers le monde, les paris sportifs représentent la deuxième forme de jeux de hasard et d’argent (JHA) la plus associée aux problèmes de jeu. Les cognitions des parieurs sportifs pourraient contribuer à cette association. Cependant, aucun outil ne semble adapté aux parieurs de loteries sportives, principalement à cause de la composante d’habileté. Cette étude vise (a) à développer l’Inventaire des cognitions à risque — Loteries sportives (ICR-LS) et en déterminer la structure factorielle, (b) à évaluer la validité de convergence de l’ICR-LS avec Gambling Related Cognitions Scale (GRCS), les habitudes de jeu, et la gravité des problèmes de jeu; et (c) à évaluer les liens entre le nombre d’heures mensuelles consacrées à la préparation des paris aux loteries sportives et les habitudes de jeu. Les parieurs sportifs recrutés (N = 272) étaient principalement de sexe masculin (86,5 %), dans la vingtaine (M = 26,7 ans) et issus de la communauté universitaire (88,3 %). Les analyses en composantes principales indiquent que l’instrument possède deux dimensions (Superstitions et Habiletés), une forte cohérence interne (les coefficients alpha > ,85) et une bonne validité convergente. Des associations négligeables, mais statistiquement significatives, ressortent entre l’ICR-LS et le montant annuel dépensé aux loteries, les heures consacrées à la préparation des paris et la gravité des problèmes de jeu. En outre, le temps consacré à la préparation des paris sportifs est modérément corrélé avec le montant dépensé, la fréquence de jeu et la gravité des problèmes de jeu, ce qui incite à y voir, peut-être, un facteur de risque lié aux loteries sportives. Le temps consacré à la préparation des paris sportifs et ses effets sur les différentes sphères de vie mériteraient d’être étudiés davantage, notamment auprès de joueurs problématiques.AbstractAround the world, sports betting is the second type of gambling activity most associated with gambling problems. Thus, sports bettors’ cognitions play an essential role in this association. However, no instrument is specifically designed to assess sports bettors’ cognitions. This study aims (a) to develop the Inventaire des cognitions à risque — Loteries sportives (ICR-LS)  and to determine its factor structure, (b) to assess the convergent validity of the ICR-LS with the Gambling Related Cognitions Scale (GRCS), gambling habits, and the severity of gambling problems; and (c) to assess the links between the number of monthly hours spent preparing for sports lottery bets and gambling habits. Participants are sport lottery bettors (N = 272) that are mainly men (86.5%) in their twenties (M = 26.7 years old), and from a university community (88.3%). Principal component analysis results indicate that the instrument is composed of two factors (Superstitions and Abilities), and shows strong internal consistency (coefficients alpha > .85) and good convergent validity. The scale shows statistically significant but negligible associations with the annual amount spent on lotteries, hours spent on the preparation of bets, and gambling problem severity. In addition, time dedicated to bet preparation is moderately associated with the amount spent, gambling frequency, and gambling problem severity, suggesting that sports bettors bet preparation time could be a risk factor in sports betting. Studies should explore further the amount of time dedicated to bet preparation and its effects on different spheres of life, especially for problem gamblers.

Rapid protein evolution, organellar reductions, and invasive intronic elements in the marine aerobic parasite dinoflagellate Amoebophrya spp

BACKGROUND

Dinoflagellates are aquatic protists particularly widespread in the oceans worldwide. Some are responsible for toxic blooms while others live in symbiotic relationships, either as mutualistic symbionts in corals or as parasites infecting other protists and animals. Dinoflagellates harbor atypically large genomes (~ 3 to 250 Gb), with gene organization and gene expression patterns very different from closely related apicomplexan parasites. Here we sequenced and analyzed the genomes of two early-diverging and co-occurring parasitic dinoflagellate Amoebophrya strains, to shed light on the emergence of such atypical genomic features, dinoflagellate evolution, and host specialization.

RESULTS

We sequenced, assembled, and annotated high-quality genomes for two Amoebophrya strains (A25 and A120), using a combination of Illumina paired-end short-read and Oxford Nanopore Technology (ONT) MinION long-read sequencing approaches. We found a small number of transposable elements, along with short introns and intergenic regions, and a limited number of gene families, together contribute to the compactness of the Amoebophrya genomes, a feature potentially linked with parasitism. While the majority of Amoebophrya proteins (63.7% of A25 and 59.3% of A120) had no functional assignment, we found many orthologs shared with Dinophyceae. Our analyses revealed a strong tendency for genes encoded by unidirectional clusters and high levels of synteny conservation between the two genomes despite low interspecific protein sequence similarity, suggesting rapid protein evolution. Most strikingly, we identified a large portion of non-canonical introns, including repeated introns, displaying a broad variability of associated splicing motifs never observed among eukaryotes. Those introner elements appear to have the capacity to spread over their respective genomes in a manner similar to transposable elements. Finally, we confirmed the reduction of organelles observed in Amoebophrya spp., i.e., loss of the plastid, potential loss of a mitochondrial genome and functions.

CONCLUSION

These results expand the range of atypical genome features found in basal dinoflagellates and raise questions regarding speciation and the evolutionary mechanisms at play while parastitism was selected for in this particular unicellular lineage.

Correlation between work impairment, scores of rhinitis severity and asthma using the MASK-air® App

BACKGROUND

In allergic rhinitis, a relevant outcome providing information on the effectiveness of interventions is needed. In MASK-air (Mobile Airways Sentinel Network), a visual analogue scale (VAS) for work is used as a relevant outcome. This study aimed to assess the performance of the work VAS work by comparing VAS work with other VAS measurements and symptom-medication scores obtained concurrently.

METHODS

All consecutive MASK-air users in 23 countries from 1 June 2016 to 31 October 2018 were included (14 189 users; 205 904 days). Geolocalized users self-assessed daily symptom control using the touchscreen functionality on their smart phone to click on VAS scores (ranging from 0 to 100) for overall symptoms (global), nose, eyes, asthma and work. Two symptom-medication scores were used: the modified EAACI CSMS score and the MASK control score for rhinitis. To assess data quality, the intra-individual response variability (IRV) index was calculated.

RESULTS

A strong correlation was observed between VAS work and other VAS. The highest levels for correlation with VAS work and variance explained in VAS work were found with VAS global, followed by VAS nose, eye and asthma. In comparison with VAS global, the mCSMS and MASK control score showed a lower correlation with VAS work. Results are unlikely to be explained by a low quality of data arising from repeated VAS measures.

CONCLUSIONS

VAS work correlates with other outcomes (VAS global, nose, eye and asthma) but less well with a symptom-medication score. VAS work should be considered as a potentially useful AR outcome in intervention studies.

Conception and use of a custom-made facial mask for pressure therapy in complex facial wounds

Pressure therapy (PT) is commonly used to manage hypertrophic scars. It is often based on the use of elastic pressure garments, which are poorly suited for a facial localization. We describe the conception, fabrication, and use of a custom-made PT facial mask for primary prevention of hypertrophic scarring of complex facial wounds. The main advantage of the device is that it is quick and easy to manufacture in a conventional prosthetics laboratory, with a good level of observance and tolerance in our experience of 20 treated patients.

[Medication management of hypertension and heart failure in older patients: What happens to therapeutic changes after hospitalization?]

PURPOSE

The objective of this study was to objectivize if the cardiovascular therapeutic changes performed during hospitalization of older patients with hypertension and/or heart failure (HF), were maintained in ambulatory 3 month after hospitalization.

METHODS

This is a longitudinal study conducted in a geriatric unit. Patients over 65 years with hypertension and/or HF, who had at least one change in cardiovascular medicaton during hospitalization, and who accepted the 3-month follow-up were included in the longitudinal study. At admission, during hospitalization and 3 months after hospitalization data concerning cardiovascular medication were collected.

RESULTS

During hospitalization, 142 (73.6%) patients had at least one change in hypertension and/or HF medication. Overall, 249 changes were performed. Forty-one patients received follow-up at 3 months. At 3 months, therapeutic changes were maintained by 48.8% of the general practitioners (n=20 patients). For the rest, 41.5% of the patients had benefited from new therapeutic changes (28 changes for 10 patients) and 9.7% of the general practitioners (n=4 patients) had restored the initial prescription before hospitalization.

CONCLUSIONS

Medication review performed by geriatricians and pharmacists during hospitalization resulted in 249 changes. These changes aimed at limiting iatrogenic disease, by reducing overtreatment and potentially inappropriate prescriptions. Difficulties in the patient care continuity between the hospital and ambulatory setting have been identified.

Effects of an individualized exercise training program on severity markers of obstructive sleep apnea syndrome: a randomised controlled trial

OBJECTIVE

Obstructive sleep apnea (OSA) is a high prevalent disorder with severe consequences including sleepiness, metabolic, and cardiovascular disorders. The aim of this study was to assess the effect of an individualized exercise-training (IET) program with educational sessions vs educational sessions alone on severity markers of OSA over an eight-week duration.

METHODS

This was a randomised, controlled, parallel-design study. In sum, 64 patients with moderate-to-severe OSA (apnea-hypopnea index AHI 15-45/hour), low physical activity level (Voorrips<9), body-mass index (BMI) <40 kg/m² were included in intervention group (IG) or control group (CG), and 54 patients finished the study. All underwent polysomnography (PSG), multiple sleep latency test (MSLT), constant workload exercise test, blood samples and fulfilled questionnaires twice. The primary endpoint was the change in apnea-hypopnea (AHI) at eight weeks from baseline. Main secondary endpoints were daytime sleepiness assessed by questionnaire and objective tests.

RESULTS

No significant between-group differences were found for changes in AHI. A reduction in AHI was found in IG only (p = 0.005). Compared to CG, exercise training leads to a greater decrease in AHI during REM sleep (p = 0.0004), with a significant increase in mean daytime sleep latency (p = 0.02). Between-group differences were significant for weight reduction, severity of fatigue, insomnia and depressive symptoms with trend for sleepiness symptoms.

CONCLUSIONS

In adult patients with moderate-to-severe OSA, IET did not decrease AHI compared to the control group but improved markers of severity of OSA, in particular AHI in rapid eye movement (REM) sleep and objective daytime sleepiness. Adding personalized exercise training to the management of patients with OSA should be considered. CLINICALTRIALS.

Pelvic floor muscle training: mechanisms of action for the improvement of genitourinary syndrome of menopause

Objective: This study aims to investigate the mechanism of action of pelvic floor muscle training (PFMT) for the improvement of the signs and symptoms of genitourinary syndrome of menopause (GSM) in postmenopausal women with GSM and urinary incontinence (UI).Methods: Twenty-nine women were included in the secondary analysis of a single-arm feasibility study. Using color Doppler ultrasound, the peak systolic velocity, time-averaged maximum velocity, and pulsatility index of the internal pudendal and dorsal clitoral arteries were measured at rest and after a pelvic floor muscle (PFM) contraction task. PFM function was assessed by dynamometry, and vulvovaginal tissue elasticity was measured using the Vaginal Atrophy Index.Results: PFMT significantly improved blood flow parameters in both arteries (p < 0.05) and significantly increased the speed of PFM relaxation after a contraction (p = 0.003). After the intervention, a marginally significant decrease in PFM tone was observed, as well as an increase in PFM strength (p = 0.060 and p = 0.051, respectively). Finally, improvements in skin elasticity and introitus width were observed as measured by the Vaginal Atrophy Index (p < 0.007).Conclusion: Our findings suggest that PFMT improves blood flow in vulvovaginal tissues, PFM relaxation capacity, and vulvovaginal tissue elasticity in postmenopausal women with GSM and UI.

[Adaptation of the General Data Protection Regulation (GDPR) to a smartphone app for rhinitis and asthma (MASK-air®)]

The General Data Protection Regulation (GDPR) regulates the processing of personal data in the European Union. The legal context is adapted to follow the evolution of technologies and of society. This new European regulation became mandatory, especially for connected devices, on May 25, 2018. An app originally known as "The Allergy Diary" is available for Android phones and iPhones. Its name was recently changed to MASK-air. The downloading and use of this app are free of charge and there are no adverts. It enables users to record their symptoms and their medications to better track the progress of their allergic rhinitis and/or asthma. It has been developed by public (Foundation FMC VIA-LR, University of Montpellier) and private (KYomed INNOV) organizations based in France and therefore falls under French jurisdiction. This article summarizes the five main principles of personal data protection to be respected during the development of the app: purpose, proportionality and relevance, limited retention period, security and confidentiality, as well as the rights of the people who are involved in the management of the personal data (including withdrawal and modification).

Vertical lengthening genioplasty: A new osteotomy technique

Vertical insufficiency of the chin imbalances the orofacial and aesthetic parameters of the lower third of the face. We here propose a new osteotomy technique for chin lengthening. Our procedure is based on a single osteotomy and it does not require any interposition of a bone graft. In our experience with seven patients, we report good aesthetic and morphometric outcomes at one year.

Keeping the pelvic floor healthy

Female pelvic floor muscles form a diaphragm that spans the entire pelvic cavity. They consist of the fibers of the coccygeus and the levator ani muscles, the latter of which is composed of five parts. Together with their fascia, the pelvic floor muscles provide support for the urethra, the vagina, and the rectum and constrict the urethral, vaginal, and anal orifices. Alterations in the composition of the pelvic floor muscles at menopause appear to affect their properties and, thereby, their ability to function adequately. This can lead to an increased prevalence in urinary incontinence and other lower urinary tract dysfunction, pelvic organ prolapse, and genitourinary syndrome of menopause. This article aims to define the pelvic floor muscles and functions and to summarize the direct and indirect changes to women's pelvic floor muscles during and after menopause and through aging. A particular focus is also given to the evidence-based literature on how to keep pelvic floor muscles healthy during menopause and in postmenopause using conservative management therapy.

Seventy four Reference Sites of the European Innovation Partnership on Active and Healthy Ageing (EIP on AHA) have been recognised by the European Commission in 2016 for their commitment to excellence in investing and scaling up innovative solutions for active and healthy ageing. The Reference Site Collaborative Network (RSCN) brings together the EIP on AHA Reference Sites awarded by the European Commission, and Candidate Reference Sites into a single forum. The overarching goals are to promote cooperation, share and transfer good practice and solutions in the development and scaling up of health and care strategies, policies and service delivery models, while at the same time supporting the action groups in their work. The RSCN aspires to be recognized by the EU Commission as the principal forum and authority representing all EIP on AHA Reference Sites. The RSCN will contribute to achieve the goals of the EIP on AHA by improving health and care outcomes for citizens across Europe, and the development of sustainable economic growth and the creation of jobs.

Oak genome reveals facets of long lifespan

Oaks are an important part of our natural and cultural heritage. Not only are they ubiquitous in our most common landscapes¹ but they have also supplied human societies with invaluable services, including food and shelter, since prehistoric times². With 450 species spread throughout Asia, Europe and America³, oaks constitute a critical global renewable resource. The longevity of oaks (several hundred years) probably underlies their emblematic cultural and historical importance. Such long-lived sessile organisms must persist in the face of a wide range of abiotic and biotic threats over their lifespans. We investigated the genomic features associated with such a long lifespan by sequencing, assembling and annotating the oak genome. We then used the growing number of whole-genome sequences for plants (including tree and herbaceous species) to investigate the parallel evolution of genomic characteristics potentially underpinning tree longevity. A further consequence of the long lifespan of trees is their accumulation of somatic mutations during mitotic divisions of stem cells present in the shoot apical meristems. Empirical⁴ and modelling⁵ approaches have shown that intra-organismal genetic heterogeneity can be selected for⁶ and provides direct fitness benefits in the arms race with short-lived pests and pathogens through a patchwork of intra-organismal phenotypes⁷. However, there is no clear proof that large-statured trees consist of a genetic mosaic of clonally distinct cell lineages within and between branches. Through this case study of oak, we demonstrate the accumulation and transmission of somatic mutations and the expansion of disease-resistance gene families in trees.

Sports Bettors: A Systematic Review

Sports betting is associated with problematic gambling behaviours. However, little is known about the profile of sports bettors. Also, it is still unclear if there are useful abilities in sports betting. This systematic review aims to describe gambling habits and cognitions of sports bettors, and determine the roles of chance and skill in sports betting. Addressing the chance and skill distinction in sports betting would be helpful to identify which of sports bettors' cognitions are erroneous. Out of 991 studies identified in the databanks, 31 met the inclusion criteria of this review. Results indicate that these studies are mostly conducted with male samples aged from 30 to 50 years. These gamblers bet many times per week, with weekly averages ranging from 100 to 200$ CAD. Five studies examined the roles of chance and skill in sports betting, among which three showed that sports bettors perform better than chance in predicting results accurately, but they do not win more money than they would with a random selection, due to the structure of the game. The 11 studies that focused on cognitions indicate that sports bettors overestimate the influence of skill on the outcome of the game. These results support the need to further study the role of cognitions in the behaviours of sports bettors. It also offers insights concerning the distinction between chance and skill in sports betting.RésuméLes paris sportifs sont associés à des comportements de jeu problématiques.

Les onze études portant sur les cognitions indiquent que les parieurs sportifs surestiment l’influence des habiletés sur l’issue du jeu. Ces résultats confirment la nécessité d’approfondir le rôle des cognitions dans les comportements des parieurs sportifs. Ils donnent également des pistes sur la distinction entre le hasard et les habiletés dans les paris sportifs.

GROOLS: reactive graph reasoning for genome annotation through biological processes

BACKGROUND

High quality functional annotation is essential for understanding the phenotypic consequences encoded in a genome. Despite improvements in bioinformatics methods, millions of sequences in databanks are not assigned reliable functions. The curation of protein functions in the context of biological processes is a way to evaluate and improve their annotation.

RESULTS

We developed an expert system using paraconsistent logic, named GROOLS (Genomic Rule Object-Oriented Logic System), that evaluates the completeness and the consistency of predicted functions through biological processes like metabolic pathways. Using a generic and hierarchical representation of knowledge, biological processes are modeled in a graph from which observations (i.e. predictions and expectations) are propagated by rules. At the end of the reasoning, conclusions are assigned to biological process components and highlight uncertainties and inconsistencies. Results on 14 microbial organisms are presented.

CONCLUSIONS

GROOLS software is designed to evaluate the overall accuracy of functional unit and pathway predictions according to organism experimental data like growth phenotypes. It assists biocurators in the functional annotation of proteins by focusing on missing or contradictory observations.

Two genomes of highly polyphagous lepidopteran pests (Spodoptera frugiperda, Noctuidae) with different host-plant ranges

Emergence of polyphagous herbivorous insects entails significant adaptation to recognize, detoxify and digest a variety of host-plants. Despite of its biological and practical importance - since insects eat 20% of crops - no exhaustive analysis of gene repertoires required for adaptations in generalist insect herbivores has previously been performed. The noctuid moth Spodoptera frugiperda ranks as one of the world’s worst agricultural pests. This insect is polyphagous while the majority of other lepidopteran herbivores are specialist. It consists of two morphologically indistinguishable strains (“C” and “R”) that have different host plant ranges. To describe the evolutionary mechanisms that both enable the emergence of polyphagous herbivory and lead to the shift in the host preference, we analyzed whole genome sequences from laboratory and natural populations of both strains. We observed huge expansions of genes associated with chemosensation and detoxification compared with specialist Lepidoptera. These expansions are largely due to tandem duplication, a possible adaptation mechanism enabling polyphagy. Individuals from natural C and R populations show significant genomic differentiation. We found signatures of positive selection in genes involved in chemoreception, detoxification and digestion, and copy number variation in the two latter gene families, suggesting an adaptive role for structural variation.

Surgical management of lower lip pits in Van der Woude syndrome

Van der Woude syndrome (VDWS) is characterized by the presence of lower lip pits which may be of concern to patients due to aesthetic considerations. By presenting three clinical cases, we provide an overview of the surgical techniques currently available to treat labial pits. Fusiform excision with dissection of the entire pit is still the most commonly used procedure and it generally yields good functional and aesthetic outcomes. The split-lip advancement technique and the inverted T-lip reduction nonetheless represent good surgical alternatives. Proper management of the lower pits that occur with VDWS requires thorough knowledge of the available surgical procedures.

MACVIA-LR (Fighting Chronic Diseases for Active and Healthy Ageing in Languedoc-Roussillon): A Success Story of the European Innovation Partnership on Active and Healthy Ageing

The Région Languedoc Roussillon is the umbrella organisation for an interconnected and integrated project on active and healthy ageing (AHA). It covers the 3 pillars of the European Innovation Partnership on Active and Healthy Ageing (EIP on AHA): (A) Prevention and health promotion, (B) Care and cure, (C) and (D) Active and independent living of elderly people. All sub-activities (poly-pharmacy, falls prevention initiative, prevention of frailty, chronic respiratory diseases, chronic diseases with multimorbidities, chronic infectious diseases, active and independent living and disability) have been included in MACVIA-LR which has a strong political commitment and involves all stakeholders (public, private, patients, policy makers) including CARSAT-LR and the Eurobiomed cluster. It is a Reference Site of the EIP on AHA. The framework of MACVIA-LR has the vision that the prevention and management of chronic diseases is essential for the promotion of AHA and for the reduction of handicap. The main objectives of MACVIA-LR are: (i) to develop innovative solutions for a network of Living labs in order to reduce avoidable hospitalisations and loss of autonomy while improving quality of life, (ii) to disseminate the innovation. The three years of MACVIA-LR activities are reported in this paper.

Online and Mobile Interventions for Problem Gambling, Alcohol, and Drugs: A Systematic Review

Online interventions for gambling, alcohol, and illegal drug related problems have been developing at a fast pace over the past decade. Yet, little is known about the content and efficacy of interventions provided entirely online for reducing drug/alcohol use and gambling, or about the characteristics of those who use these interventions. This systematic review aims to describe the characteristics of online interventions, their efficacy, and the profile of their clientele. Documentation was mainly obtained through four scientific databases in psychology, technology, and medical research (PsychINFO, MedLine, Francis, and INSPEC) using three keywords (substances or gambling, intervention, Internet). Of the 4,708 documents initially identified, 18 studies meeting admissibility criteria were retained and analyzed after exclusion of duplicates and non-relevant documents. No study in the review related to problem gambling. The majority of interventions were based upon motivational or cognitive-behavioral theoretical approaches and called upon well-established therapeutic components in the field of addictions. The participants in these studies were generally adults between 30 and 46 years old with a high school education and presenting a high risk or problematic use. More than three quarters of the studies showed a short-term decrease in use that was maintained 6 months later, but only two studies included a 12 months follow-up. Online interventions seem promising and appear to meet the needs of participants who are in the workforce and seeking help for the first time. Long-term efficacy studies should nonetheless be conducted.

Building Bridges for Innovation in Ageing: Synergies between Action Groups of the EIP on AHA

The Strategic Implementation Plan of the European Innovation Partnership on Active and Healthy Ageing (EIP on AHA) proposed six Action Groups. After almost three years of activity, many achievements have been obtained through commitments or collaborative work of the Action Groups. However, they have often worked in silos and, consequently, synergies between Action Groups have been proposed to strengthen the triple win of the EIP on AHA. The paper presents the methodology and current status of the Task Force on EIP on AHA synergies. Synergies are in line with the Action Groups' new Renovated Action Plan (2016-2018) to ensure that their future objectives are coherent and fully connected. The outcomes and impact of synergies are using the Monitoring and Assessment Framework for the EIP on AHA (MAFEIP). Eight proposals for synergies have been approved by the Task Force: Five cross-cutting synergies which can be used for all current and future synergies as they consider overarching domains (appropriate polypharmacy, citizen empowerment, teaching and coaching on AHA, deployment of synergies to EU regions, Responsible Research and Innovation), and three cross-cutting synergies focussing on current Action Group activities (falls, frailty, integrated care and chronic respiratory diseases).

ARIA 2016: Care pathways implementing emerging technologies for predictive medicine in rhinitis and asthma across the life cycle

The Allergic Rhinitis and its Impact on Asthma (ARIA) initiative commenced during a World Health Organization workshop in 1999. The initial goals were (1) to propose a new allergic rhinitis classification, (2) to promote the concept of multi-morbidity in asthma and rhinitis and (3) to develop guidelines with all stakeholders that could be used globally for all countries and populations. ARIA—disseminated and implemented in over 70 countries globally—is now focusing on the implementation of emerging technologies for individualized and predictive medicine. MASK [MACVIA (Contre les Maladies Chroniques pour un Vieillissement Actif)-ARIA Sentinel NetworK] uses mobile technology to develop care pathways for the management of rhinitis and asthma by a multi-disciplinary group and by patients themselves. An app (Android and iOS) is available in 20 countries and 15 languages. It uses a visual analogue scale to assess symptom control and work productivity as well as a clinical decision support system. It is associated with an inter-operable tablet for physicians and other health care professionals. The scaling up strategy uses the recommendations of the European Innovation Partnership on Active and Healthy Ageing. The aim of the novel ARIA approach is to provide an active and healthy life to rhinitis sufferers, whatever their age, sex or socio-economic status, in order to reduce health and social inequalities incurred by the disease.

Combining balneotherapy and health promotion to promote active and healthy ageing: the Balaruc-MACVIA-LR® approach

Scaling up and replication of successful innovative integrated care models for chronic diseases is one of the targets of the European Innovation Partnership on Active and Healthy Ageing (EIP on AHA). MACVIA-LR^® (MAladies Chroniques pour un VIeillissement Actif en Languedoc-Roussillon) is a Reference Site of the EIP on AHA. The main objective of MACVIA-LR^® is to develop innovative solutions in order to (1) improve the care of patients affected by chronic diseases, (2) reduce avoidable hospitalization and (3) scale up the innovation to regions of Europe. The MACVIA-LR^® project also aims to assess all possible aspects of medicine—including non-pharmacologic approaches—in order to maintain health and prevent chronic diseases. These approaches include hydrotherapy and balneotherapy which can be of great importance if health promotion strategies are considered. Balneotherapy at Balaruc-les-Bains focusses on musculoskeletal diseases and chronic venous insufficiency of the lower limbs. Each year, over 46,000 people attend an 18-day course related to a new falls prevention initiative combining balneotherapy and education. On arrival, each person receives a flyer providing information on the risk of fall and, depending on this risk, a course is proposed combining education and physical activity. A pilot study assesses the impact of the course 6 and 12 months later. This health promotion strategy for active and healthy ageing follows the FEMTEC (World Federation of Hydrotherapy and Climatotherapy) concept.

MicroScope in 2017: an expanding and evolving integrated resource for community expertise of microbial genomes

The annotation of genomes from NGS platforms needs to be automated and fully integrated. However, maintaining consistency and accuracy in genome annotation is a challenging problem because millions of protein database entries are not assigned reliable functions. This shortcoming limits the knowledge that can be extracted from genomes and metabolic models. Launched in 2005, the MicroScope platform (http://www.genoscope.cns.fr/agc/microscope) is an integrative resource that supports systematic and efficient revision of microbial genome annotation, data management and comparative analysis. Effective comparative analysis requires a consistent and complete view of biological data, and therefore, support for reviewing the quality of functional annotation is critical. MicroScope allows users to analyze microbial (meta)genomes together with post-genomic experiment results if any (i.e. transcriptomics, re-sequencing of evolved strains, mutant collections, phenotype data). It combines tools and graphical interfaces to analyze genomes and to perform the expert curation of gene functions in a comparative context. Starting with a short overview of the MicroScope system, this paper focuses on some major improvements of the Web interface, mainly for the submission of genomic data and on original tools and pipelines that have been developed and integrated in the platform: computation of pan-genomes and prediction of biosynthetic gene clusters. Today the resource contains data for more than 6000 microbial genomes, and among the 2700 personal accounts (65% of which are now from foreign countries), 14% of the users are performing expert annotations, on at least a weekly basis, contributing to improve the quality of microbial genome annotations.

Scaling up strategies of the chronic respiratory disease programme of the European Innovation Partnership on Active and Healthy Ageing (Action Plan B3: Area 5)

Action Plan B3 of the European Innovation Partnership on Active and Healthy Ageing (EIP on AHA) focuses on the integrated care of chronic diseases. Area 5 (Care Pathways) was initiated using chronic respiratory diseases as a model. The chronic respiratory disease action plan includes (1) AIRWAYS integrated care pathways (ICPs), (2) the joint initiative between the Reference site MACVIA-LR (Contre les MAladies Chroniques pour un VIeillissement Actif) and ARIA (Allergic Rhinitis and its Impact on Asthma), (3) Commitments for Action to the European Innovation Partnership on Active and Healthy Ageing and the AIRWAYS ICPs network. It is deployed in collaboration with the World Health Organization Global Alliance against Chronic Respiratory Diseases (GARD). The European Innovation Partnership on Active and Healthy Ageing has proposed a 5-step framework for developing an individual scaling up strategy: (1) what to scale up: (1-a) databases of good practices, (1-b) assessment of viability of the scaling up of good practices, (1-c) classification of good practices for local replication and (2) how to scale up: (2-a) facilitating partnerships for scaling up, (2-b) implementation of key success factors and lessons learnt, including emerging technologies for individualised and predictive medicine. This strategy has already been applied to the chronic respiratory disease action plan of the European Innovation Partnership on Active and Healthy Ageing.
