Choice of ICD‐10 codes for the identification of acute coronary syndrome in the French hospitalization database

The objective of this study was to evaluate the performance of the ICD‐10 (International Classification of Diseases and Related Health Problems, 10^th Edition) coding in the French hospitalization database (PMSI) to identify acute coronary syndrome (ACS) occurrence. Eligible hospitalizations were those that occurred at the Bordeaux teaching hospitals between 1 January 2011 and 31 December 2011 and had one of the ICD‐10 codes related to ischaemic heart diseases (I20 to I25, excluding I23 and I25.2). Among these, 100 hospitalizations were randomly selected; for each case, the ACS diagnosis was confirmed/excluded after medical file examination by an independent events validation committee and the performance of codes, and combinations of codes, to identify ACS was evaluated by calculating the positive predictive value (PPV). Of the individual codes, I20.0, I21 and I24 had the highest PPV; 100.0% for I24 (95%CI [15.8–100.0]); 90.0% for I21 (95%CI [76.3–97.2]); and 66.7% for I20.0 (95%CI [38.4–88.2]). The combination of I20.0 or I24 codes was able to identify 12 of the 56 validated ACS cases with a PPV of 70.6% (95%CI [44.0–89.7]), the combination of I21 or I24 identified 38 cases with a PPV of 90.5% (95%CI [77.4–97.3]), the combination of I20.0 or I21 identified 46 cases with a PPV of 83.6% (95%CI [71.2–92.2]), and the combination of I20.0, I21 or I24 identified 48 cases with a PPV of 84.2% (95%CI [72.1–92.5]). The combination of I20.0, I21 or I24 codes had the best performance to identify occurrence of ACS in the French hospitalization database.     

Retrospective analysis of clinical outcomes in bilateral cleft lip and palate patients after secondary alveolar bone grafting and premaxilla osteotomy,using a new dento-maxillary scoring system

Evaluation of relevant clinical outcomes in patients with bilateral cleft lip and palate (BCLP) after secondary aveolar bone grafting (SABG) and premaxilla osteotomy (PMO), through the use of a new scoring system.Data were collected retrospectively from all patients with BCLP who were operated on between 2004 and 2014, at the end of follow-up. The treatment protocol consisted of SABG + PMO in patients aged between 9 and 13 years. At the end of follow-up, the following parameters were scored: (un)interrupted dental arch, skeletal sagittal relationship, bone height using the Bergland/Abyholm criteria, and the presence of postoperative fistula. These parameters were combined to produce a dento-maxillary scoring system, giving a final score between 1 and 10. For statistical analysis, the independent t-test was used.Of 55 children, 45 were suitable for analysis. The mean age at time of surgery was 12.0 years (8.9–16.4 yrs), and the mean follow-up time was 11.7 years (5.8–15.8 yrs). The average number of surgeries executed under general anesthesia was 6 (range: 3–11). The average dento-maxillary score in this patient cohort was 7.6 (1–10; median: 8). Among these patients, 31 had an uninterrupted dental arch; the average Bergland/Abyholm score was 2.07; 30 patients exhibited an Angle class I incisor relationship; and, in 38 cases, the oronasal communication was closed after SABG + PMO treatment. A significant effect of fistulas was seen on dento-maxillary score (p = 0.001). Specifically, a significant effect of fistulas was seen on interrupted dental arch (p = 0.002) and on Bergland/Abyholm score (p = 0.037).The proposed dento-maxillary scoring system is a straightforward tool that can be used to describe and analyze the amount of dento-maxillary rehabilitation at the end of the treatment. Persistence of oronasal fistulas in patients with BCLP has a significant impact on interruption of the dental arch, and can influence dental results at the end of the second decade.     

First inappropriate implantable cardioverter defibrillator therapy is often due to inaccurate device programming: analysis of the French OPERA registry

AIMS: Inappropriate therapy delivered by implantable cardioverter defibrillators (ICDs) remains a challenge. The OPERA registry measured the times to, and studied the determinants of, first appropriate (FAT) and inappropriate (FIT) therapies delivered by single-, dual- and triple-chamber [cardiac resynchronization therapy defibrillator (CRT-D)] ICD. METHODS AND RESULTS: We entered 636 patients (mean age = 62.0 ± 13.5 years; 88% men) in the registry, of whom 251 received single-, 238 dual-, and 147 triple-chamber ICD, for primary (30.5%) or secondary (69.5%) indications. We measured times to FAT and FIT as a function of multiple clinical characteristics, examined the effects of various algorithm components on the likelihood of FAT and FIT delivery, and searched for predictors of FAT and FIT. Over 22.8 ± 8.8 months of observation, 184 patients (28.9%) received FAT and 70 (11.0%) received FIT. Ventricular tachycardia (VT) was the trigger of 88% of FAT, and supraventricular tachycardia was the trigger of 91% of FIT. The median times to FIT (90 days; range 49-258) and FAT (171 days; 50-363) were similar. The rate of FAT was higher (P <0.001) in patients treated for secondary than primary indications, while that of FIT were similar in both groups. Out of 57 analysable FIT, 27 (47.4%) could have been prevented by fine tuning the device programming like the sustained rate duration or the VT discrimination algorithm. CONCLUSIONS: First inappropriate therapy occurred in 11% of 636 ICD recipients followed for ～2 years. Nearly 50% of FIT could have been prevented by improving device programming.     

The harmful-dysfunction account of disorder,individual versus social values,and the interpersonal variability of harm challenge

This paper presents the interpersonal variability of harm challenge to Jerome Wakefield’s harmful-dysfunction account (HDA) of disorder. This challenge stems from the seeming fact that what promotes well-being or is harmful to someone varies much more across individuals than what is intuitively healthy or disordered. This makes it at least prima facie difficult to see how judgments about health and disorder could, as harm-requiring accounts of disorder like the HDA maintain, be based on, or closely linked to, judgments about well-being and harm. This interpersonal variability of harm challenge is made salient by the difficulty faced by harm-requiring accounts of disorder in dealing satisfactorily with cases of intuitively disordered conditions that seem harmless because they do not deprive the individuals that they affect of anything that they value (e.g., desired infertility). I argue that this challenge is made more serious for the HDA by some clarifications Wakefield has recently made on harm. In recent publications, Wakefield dissociates himself from the sheer cultural-relativist view of harm attributed to him by some critics based on his linkage of harm to social values, and adopts a more qualified social-values-based view of harm that leaves room for criticism of the values endorsed by members of a cultural group at a given time. I show how Wakefield’s qualified view makes it more difficult for the HDA to deal with the interpersonal variability of harm challenge, at least when applied to a Western cultural context where a high value is placed on autonomy and individual choice.

     

Thérapies comportementales et cognitives des phobies sociales : programmes classiques et nouvelles approches

Social phobia (SP) is a prevalent and impairing condition, occurring especially in young subjects with deleterious consequences on their occupational and familial functioning. Cognitive behavioural therapy (CBT) has been shown to be effective for the treatment of SP in many studies for about 20 years. Validated components of this treatment can include psychoeducation, social skills training, in vivo exposure, video feedback, and cognitive restructuring. Other complementary methods, coming from the CBT, have been also integrated in therapeutic programs during last years. This is the case for example of specific techniques focused on fear of blushing (erythrophobia), based on the task concentration training. Eye movement desensitization and reprocessing therapy can be also interesting for the treatment of patients with past traumatic social experiences, as well as mindfulness meditation for the prevention of relapses after a CBT. Researches are conducted on the use of new technologies for web therapy or virtual reality exposure therapy. Lastly, drug facilitation of exposure therapy is a great challenge for the treatment of SP, and positive results have been recently obtained with agents like d-cycloserine or oxytocin.     

Seroprevalence of Human Malawi Polyomavirus

The seroprevalence of the recently discovered human Malawi polyomavirus (MWPyV) was determined by virus-like particle-based enzyme-linked immunosorbent assay (ELISA) in age-stratified Italian subjects. The findings indicated that MWPyV infection occurs early in life, and seroprevalence was shown to reach 42% in adulthood.     

Maternally acquired genotoxic Escherichia coli alters offspring’s intestinal homeostasis

The neonatal gut is rapidly colonized by a newly dominant group of commensal Escherichia coli strains among which a large proportion produces a genotoxin called colibactin. In order to analyze the short- and long-term effects resulting from such evolution, we developed a rat model mimicking the natural transmission of E. coli from mothers to neonates. Genotoxic and non-genotoxic E. coli strains were equally transmitted to the offspring and stably colonized the gut across generations. DNA damage was only detected in neonates colonized with genotoxic E. coli strains. Signs of genotoxic stress such as anaphase bridges, higher occurrence of crypt fission and accelerated renewal of the mature epithelium were detected at adulthood. In addition, we observed alterations of secretory cell populations and gut epithelial barrier. Our findings illustrate how critical is the genotype of E. coli strains acquired at birth for gut homeostasis at adulthood.
