De la recommandation d'un dépistage à son (non) implantation: le cas de l'anévrisme de l'aorte abdominale. [From guidelines for screening to their (poor) implementation: the case of the abdominal aortic aneurysm].

Suite à des essais cliniques randomisés démontrant l'efficacité du dépistage de l'anévrisme de l'aorte abdominale (AAA) par échographie, plusieurs recommandations ont été publiées dans de nombreux pays en faveur du dépistage dans une partie de la population générale. De plus, au-delà de la rupture aortique, le dépistage d'un petit AAA semble être une bonne occasion d'appliquer les stratégies de prévention secondaire, permettant une amélioration globale du pronostic cardiovasculaire du patient. Ces recommandations sont cependant peu suivies; les campagnes de dépistage systématique sont rares, laissant la responsabilité du dépistage au médecin généraliste. Cet article se propose de discuter les raisons de la non-implantation du dépistage de l'AAA. [Abstract] Following the evidence of benefits of ultrasound screening for abdominal aorta aneurysms (AAA), several guidelines support this screening in population. Beyond the prompt diagnosis of AAA prior to its rupture of grim vital prognosis, small AAA can beconsidered as a prognostic marker for cardiovascular diseases (CVD). Yet, its detection is an opportunity for secondary prevention to reduce CVD mortality. Despite, these guidelines are poorly applied: systematic screening campaigns are infrequent, making the screening of family physicians responsibility. While the major benefit from this screening strategy is to reduce AAA-related death (but only trivial effect on long-term total mortality), this explains only partially the lack of guidelines implementation. The reasons of the poor implementation of these guidelines are discussed herein.

Prioritizing genetic testing in patients with kallmann syndrome using clinical phenotypes.

Context: The complexity of genetic testing in Kallmann syndrome (KS) is growing and costly. Thus, it is important to leverage the clinical evaluations of KS patients to prioritize genetic screening. Objective: The objective of the study was to determine which reproductive and nonreproductive phenotypes of KS subjects have implications for specific gene mutations. Subjects: Two hundred nineteen KS patients were studied: 151 with identified rare sequence variants (RSVs) in 8 genes known to cause KS (KAL1, NELF, CHD7, HS6ST1, FGF8/FGFR1, or PROK2/PROKR2) and 68 KS subjects who remain RSV negative for all 8 genes. Main Outcome Measures: Reproductive and nonreproductive phenotypes within each genetic group were measured. Results: Male KS subjects with KAL1 RSVs displayed the most severe reproductive phenotype with testicular volumes (TVs) at presentation of 1.5 ± 0.1 mL vs 3.7 ± 0.3 mL, P < .05 vs all non-KAL1 probands. In both sexes, synkinesia was enriched but not unique to patients with KAL1 RSVs compared with KAL1-negative probands (43% vs 12%; P < .05). Similarly, dental agenesis and digital bone abnormalities were enriched in patients with RSVs in the FGF8/FGFR1 signaling pathway compared with all other gene groups combined (39% vs 4% and 23% vs 0%; P < .05, respectively). Hearing loss marked the probands with CHD7 RSVs (40% vs 13% in non-CHD7 probands; P < .05). Renal agenesis and cleft lip/palate did not emerge as statistically significant phenotypic predictors. Conclusions: Certain clinical features in men and women are highly associated with genetic causes of KS. Synkinesia (KAL1), dental agenesis (FGF8/FGFR1), digital bony abnormalities (FGF8/FGFR1), and hearing loss (CHD7) can be useful for prioritizing genetic screening.

Bioinformatics-driven identification and examination of candidate genes for non-alcoholic fatty liver disease.

ObjectiveCandidate genes for non-alcoholic fatty liver disease (NAFLD) identified by a bioinformatics approach were examined for variant associations to quantitative traits of NAFLD-related phenotypes.Research Design and MethodsBy integrating public database text mining, trans-organism protein-protein interaction transferal, and information on liver protein expression a protein-protein interaction network was constructed and from this a smaller isolated interactome was identified. Five genes from this interactome were selected for genetic analysis. Twenty-one tag single-nucleotide polymorphisms (SNPs) which captured all common variation in these genes were genotyped in 10,196 Danes, and analyzed for association with NAFLD-related quantitative traits, type 2 diabetes (T2D), central obesity, and WHO-defined metabolic syndrome (MetS).Results273 genes were included in the protein-protein interaction analysis and EHHADH, ECHS1, HADHA, HADHB, and ACADL were selected for further examination. A total of 10 nominal statistical significant associations (P<0.05) to quantitative metabolic traits were identified. Also, the case-control study showed associations between variation in the five genes and T2D, central obesity, and MetS, respectively. Bonferroni adjustments for multiple testing negated all associations.ConclusionsUsing a bioinformatics approach we identified five candidate genes for NAFLD. However, we failed to provide evidence of associations with major effects between SNPs in these five genes and NAFLD-related quantitative traits, T2D, central obesity, and MetS.
