RESUMO
BACKGROUND: Store-and-forward (SAF) tele-dermatology (TD) platforms could help promote coordination between hospital and general practitioners (GPs). However, very little data exists on the performance accuracy and opinions of GPs participating in this type of project in France. METHODS: We report on the diagnostic and management plan accuracy of an SAF-TD platform developed for neighbouring GPs around our hospital compared with routine face-to-face (FTF) dermatological consultation in our department. We also compared the accuracy of SAF-TD with that of the participating GPs. Lastly, we collected feedback from GPs after their participation in this project. RESULTS: Overall, 298 patients were included by 58 GPs between November 2016 and January 2020, of whom 169 (57%) were female, and with a median age of 44.5 years (range 0-96). The diagnostic accuracy of TD was 62% (n=184/298) for the initial hypothesis and 80% (n=239/298) for aggregated diagnostic accuracy. Management plan accuracy for TD was 81% (n=225/277). At least 43% of consultations (n=127/298) met the criteria for preventable consultation. Diagnostic accuracy for the initial hypothesis was significantly lower for GPs than for TD (Odd Ratio [OR]=0.34; 95% Confidence Interval [95% CI]: 0.20-0.56; p<0.0001), as was management plan accuracy (OR=0.23; 95% CI: 0.10-0.46; p<0.0001). Among the responding GPs, 78% (n=29) reported very high satisfaction and 97% would consider integrating this type of programme in their long-term practice, but they highlighted the time-consuming nature of the platform (46%) and the lack of financial compensation (44%). CONCLUSION: SAF-TD in coordination with GPs seems safe and efficient in the management of outpatients, and enjoys a high satisfaction rate among GPs, despite its time-consuming nature and the lack of financial compensation. Healthcare policy should promote financial participation to help the expansion of TD.

Objectives: This study aimed to explore whether certain clinical tests or a rapid improvement in lateral hip pain following periarticular injection are predictive of subsequent efficacy of local glucocorticoid (GC) injection in greater trochanteric pain syndrome (GTPS).Method: This secondary analysis of a randomized controlled trial of an injection of GC and local anaesthetic (LA) versus placebo included 44 patients with GTPS. Two subgroups of patients were defined: (i) 30 min responders, reporting a decrease of ≥ 50% of the initial pain at 30 min post-injection; and (ii) positive triple test, presenting a combination of three positive clinical tests (30-second single-leg stance, FABER, and Lequesne). Median level of numeric rating scale for pain at 1 month was the primary outcome. Interaction analysis of treatment effect in the subgroups was performed using a linear regression adjusting for pain at baseline.Results: Sixteen patients (36%) were 30 min responders. In this group, GC treatment was associated with a significant improvement in pain at 1 month compared to non-responders (p = 0.03). The 30 min response was not associated with the use of LA. Positive triple test (22% of patients) was associated with higher pain scores at baseline (p = 0.03). In this group, patients who received placebo had significantly more pain at 1 month than those with the cortisone injection (p = 0.04).Conclusion: Patients with GTPS who present a rapid decrease in pain after periarticular injection, and those who display a combination of three specific clinical tests, are more likely to benefit from an injection with GC and anaesthetic.

OBJECTIVE: Dynamic analysis can be used to study the changes of self-regulated biological processes driven by external stimuli. Recently, the changes of heart rate during effort tests has successfully been adjusted using a simple first-order differential equation model driven by body power expenditure. Although this approach produces valid estimates and yields pertinent indices for the analysis of such measurements, it suffers from an inability to model the saturation of the heart-rate increase at high power expenditures and the change of heart-rate equilibrium following effort. APPROACH: We propose a new analysis allowing the estimation of changes of the heart rate in response to effort (gain) as a function of the power expenditure value. MAIN RESULTS: When applied to the measured heart rates of 30 amateur athletes performing a maximum graded-effort treadmill test, the proposed model was able to predict 99% of the heart rate change measured during exercise. The estimated gains decreased with a power increase above the first ventilatory threshold. This trend was stronger above the second ventilatory threshold and was strongly correlated with the maximum oxygen consumption. SIGNIFICANCE: The proposed approach yields a highly precise model of heart rate dynamics during variable effort that reflects the changes of metabolic energy systems at play during exercise.

Performance is usually assessed by simple indices stemming from cardiac and respiratory data measured during graded exercise test. The goal of this study is to characterize the indices produced by a dynamical analysis of HR and VO2 for different effort test protocols, and to estimate the construct validity of these new dynamical indices by testing their links with their standard counterparts. Therefore, two groups of 32 and 14 athletes from two different cohorts performed two different graded exercise testing before and after a period of training or deconditioning. Heart rate (HR) and oxygen consumption (VO2) were measured. The new dynamical indices were the value without effort, the characteristic time and the amplitude (gain) of the HR and VO2 response to the effort. The gain of HR was moderately to strongly associated with other performance indices, while the gain for VO2 increased with training and decreased with deconditioning with an effect size slightly higher than VO2 max. Dynamical analysis performed on the first 2/3 of the effort tests showed similar patterns than the analysis of the entire effort tests, which could be useful to assess individuals who cannot perform full effort tests. In conclusion, the dynamical analysis of HR and VO2 obtained during effort test, especially through the estimation of the gain, provides a good characterization of physical performance, robust to less stringent effort test conditions.
RESUMO
OBJECTIVE: To determine the predictive value of vertical incomitance for diplopia outcome in orbital fracture patients. PATIENTS AND METHODS: A prospective cohort study composed of patients with orbital fractures was designed. The predictor variable was vertical incomitance, and the primary outcome variable was diplopia. Incomitance was calculated in prism diopters (Δ) as the difference of the maximum absolute deviation between the upper and lower three gaze directions. Standard statistics for patient characteristics, the Fisher exact test for categorical variables and the Wilcoxon rank sum test for continuous variables were computed. RESULTS: The sample was composed of 188 patients grouped as follows: non-operated (n = 124) and operated (n = 64). Fifty-one patients showed vertical incomitance of whom 10 (19.6%) had persistent diplopia at the 1-year follow-up. The mean incomitance was 9.6Δ in the diplopia group versus 2Δ in the non diplopia group (OR = 1.13; p < 0.001). There was a statistically significant association between vertical incomitance of >2Δ and persistent diplopia at 1 year after adjusting for the surgery variable (OR = 1.07; p < 0.04). CONCLUSION: The present study has demonstrated that in orbital fracture patients, vertical incomitance was associated with (1) persistence of long-term diplopia, (2) the decision to perform surgery, and (3) the severity of the fracture.

OBJECTIVE: To investigate the presence of eosinophils in oral intraepithelial neoplasia (OIN) and oral squamous cell carcinoma (OSCC) lesions and its relation to invasion. SUBJECTS AND METHODS: Ninety-nine oral biopsies were selected and subdivided into the following: OIN-1(16 cases), OIN-2 (18 cases), OIN-3 (17 cases), microinvasive OSCC (10 cases), non-metastatic OSCC (22 cases) and metastatic OSCC (16 cases). The tissue eosinophilia was evaluated histologically in slices stained with haematoxylin and eosin. RESULTS: Eosinophil distribution was associated with diagnosis severity (p < .01). A significant difference was found between OIN-3 or microinvasive OSCC and non-metastatic or metastatic OSCC. Stromal invasion threshold was 7 eos/10 high power field (hpf) (96.1% specificity and 62.5% sensitivity). Eosinophils were absent in OIN-1; in OIN-2, two cases were positive. In OIN-3, five cases showed tissue eosinophilia, four of which had ≥3 eos/hpf or ≥7 eos/10 hpf. Three cases were suspected of invasion; two had a previous history of OSCC with elevated eosinophil infiltrate. In microinvasive OSCC, the four positive cases presented ≥3 eos/hpf and ≥7 eos/10 hpf. Although not significantly different, non-metastatic invasive OSCC had a higher number of cases (68.2%) with ≥22 eos/10 hpf contrasting with 50% in metastatic OSCC. CONCLUSION: Our results suggest that eosinophils can be considered an indicator of invasion in OIN, helping in cases of difficult diagnosis.

In the context of a worldwide obesity epidemic, healthcare providers play a key role in obesity management. Knowledge of current guidelines and attitudes to prevent stigmatization are especially important. This study aimed to assess knowledge, attitudes, beliefs, perception of opportunity for intervention, declared practices and need for training and material of nurses and physicians about obesity in a Swiss University Hospital. A total of 834 physicians and nurses filled an online survey. The questionnaire was based on literature, exploratory interviews and expert committee review. It was pre-tested with 15 physicians and nurses. Participants declared a low level of negative attitudes towards individuals living with obesity. However, the results highlighted a lack of knowledge to diagnose obesity in adults and children, as well as confidence and training to care of patients with obesity. One-third of providers did not know how to calculate body mass index. Half of providers felt it was part of their role to take care of patients with obesity, even if 55% of them had the feeling that they did not have adequate training. Nurses and physicians working in a university hospital showed a low level of negative attitudes but a lack of knowledge and skills on obesity management. Training should be improved in this population to insure adequate and coherent messages and equal access to evidence-based treatment for patients living with obesity.

BACKGROUND: Response to disease modifying antirheumatic drugs (DMARDs) in rheumatoid arthritis (RA) is often heterogeneous. We aimed to identify types of disease activity trajectories following the initiation of a new biologic DMARD (bDMARD). METHODS: Pooled analysis of nine national registries of patients with diagnosis of RA, who initiated Abatacept and had at least two measures of disease activity (DAS28). We used growth mixture models to identify groups of patients with similar courses of treatment response, and examined these patients' characteristics and effectiveness outcomes. FINDINGS: We identified three types of treatment response trajectories: 'gradual responders' (GR; 3576 patients, 91·7%) had a baseline mean DAS28 of 4·1 and progressive improvement over time; 'rapid responders' (RR; 219 patients, 5·6%) had higher baseline DAS28 and rapid improvement in disease activity; 'inadequate responders' (IR; 103 patients, 2·6%) had high DAS28 at baseline (5·1) and progressive worsening in disease activity. They were similar in baseline characteristics. Drug discontinuation for ineffectiveness was shorter among inadequate responders (p=0.03), and EULAR good or moderate responses at 1year was much higher among 'rapid responders' (p<0.001). INTERPRETATION: Clinical information and baseline clinical characteristics do not allow a reliable prediction of which trajectory the patients will follow after bDMARD initiation.

OBJECTIVE: To investigate the role of rheumatoid factor (RF) status and anti-citrullinated peptide antibody (ACPA) status as predictors of abatacept (ABA) effectiveness in patients with rheumatoid arthritis (RA). METHODS: We conducted a pooled analysis of data from 9 observational RA registries in Europe (ARTIS [Sweden], ATTRA [Czech Republic], BIOBADASER [Spain], DANBIO [Denmark], GISEA [Italy], NOR-DMARD [Norway], ORA [France], Reuma.pt [Portugal], and SCQM-RA [Switzerland]). Inclusion criteria were a diagnosis of RA, initiation of ABA treatment, and available information on RF and/or ACPA status. The primary end point was continuation of ABA treatment. Secondary end points were ABA discontinuation for ineffectiveness or adverse events and response rates at 1 year (good or moderate response according to the European League Against Rheumatism criteria with LUNDEX adjustment for treatment continuation). Hazard ratios (HRs) and 95% confidence intervals (95% CIs) for the study end points in relation to RF and ACPA status were calculated. RESULTS: We identified 2,942 patients with available data on RA-associated autoantibodies; data on RF status were available for 2,787 patients (77.0% of whom were RF positive), and data on ACPA status were available for 1,903 patients (71.3% of whom were ACPA positive). Even after adjustment for sociodemographic and disease- and treatment-related confounders, RF and ACPA positivity were each associated with a lower risk of ABA discontinuation for any reason (HR 0.79 [95% CI 0.69-0.90], P < 0.001 and HR 0.78 [95% CI 0.68-0.90], P < 0.001, respectively), compared to RF-negative and ACPA-negative patients. Similar associations with RF and ACPA were observed for discontinuation of ABA treatment due to ineffectiveness, with HRs of 0.72 (95% CI 0.61-0.84) and 0.74 (95% CI 0.62-0.88), respectively (both P < 0.001). CONCLUSION: Our results strongly suggest that positivity for RF or ACPA is associated with better effectiveness of ABA therapy.

PURPOSE: The Core Outcome Measure Index (COMI) is a multidimensional questionnaire that investigates five dimensions in low back pain (LBP) patients, but does not address the psychological dimension. As the biopsychosocial perspective is recognized as important to capture the entire clinical picture of these patients, this multicenter prospective cohort study was designed to investigate the psychometric properties of a modified version of the COMI (COMIAD) which included 2 additional items, exploring anxiety and depression, respectively. METHODS: 168 subacute or chronic LBP patients recruited in spine clinics completed a set of questionnaires before and after treatment (follow-up at 6 months). Construct validity was explored by comparing each item of the COMIAD to validated full-length questionnaires. Thus two additional questionnaires were included to assess the construct validity of the anxiety and depression measures. The psychometric properties of the COMI and COMIAD were then compared. RESULTS: The two new items showed good internal consistency, high correlations with the corresponding full-length questionnaires, no floor or ceiling effect and good reproducibility (test-retest agreement kappa 0.68 for anxiety, 0.62 for depression). The addition of the 2 items did not alter internal validity (Cronbach's alpha = 0.88 and 0.87, respectively). The smallest detectable difference, the Minimal Clinically Important Improvement and the Patient Acceptable Symptom State were only minimally affected by the changes. CONCLUSION: The questions exploring anxiety and depression have good intrinsic and psychometric capacities (i.e., no floor or ceiling effects and high correlations with full-length scales) and did not significantly modify the psychometrics of the original COMI questionnaire. The COMIAD offers the possibility to include the psychological dimension in the multidimensional evaluation without significantly affecting questionnaire length.

Pooling the hazard ratios is not always feasible in meta-analyses of two-arm survival studies, because the measure of the intervention effect is not systematically reported. An alternative approach proposed by Moodie et al. is to use the survival probabilities of the included studies, all collected at a single point in time: the intervention effect is then summarised as the pooled ratio of the logarithm of survival probabilities (which is an estimator of the hazard ratios when hazards are proportional). In this article, we propose a generalization of this method. By using survival probabilities at several points in time, this generalization allows a flexible modeling of the intervention over time. The method is applicable to partially proportional hazards models, with the advantage of not requiring the specification of the baseline survival. As in Moodie et al.'s method, the study-level factors modifying the survival functions can be ignored as long as they do not modify the intervention effect. The procedures of estimation are presented for fixed and random effects models. Two illustrative examples are presented.

Accumulating evidence suggests that periodontal infections may have an impact on systemic health. In patients with untreated periodontitis, very high values for several inflammatory markers in serum are expressed simultaneously. We investigated to what extent these peak values change after nonsurgical and surgical periodontal treatment, with adjunctive antibiotics administered during the first or the second treatment phase. In a single-center, randomized, placebo-controlled, and double-masked clinical trial, 80 patients with chronic or aggressive periodontitis were randomized into 2 treatment groups: group A, receiving systemic amoxicillin and metronidazole during the first, nonsurgical phase of periodontal therapy (phase 1), and group B, receiving the antibiotics during the second, surgical phase (phase 2). Serum samples were obtained at baseline (BL), 3 mo after phase 1 (M3), and 6 and 12 mo after phase 2 (M6, M12). Samples were evaluated for 15 cytokines and 9 acute-phase proteins using the Bio-Plex bead array multianalyte detection system. For each analyte, peak values were defined as greater than mean +2 SD of measurements found in 40 periodontally healthy persons. Sixty-six patients showed a peak value of at least 1 analyte at BL. At M12, the number of these patients was only 36 (P = 0.0002). This decrease was stronger in group A (BL: 35, M12: 19, P = 0.0009) than in group B (BL: 31, M12: 17, P = 0.14). Twenty patients displayed peak values of at least 4 biomarkers at BL. The nonsurgical therapy delivered in the first phase reduced most of these peaks (group A, BL: 9, M3: 4, P = 0.17; group B, BL: 11, M3: 2, P = 0.01), irrespective of adjunctive antibiotics. The reductions obtained at M3 were maintained until M12 in both groups. Initial, nonsurgical periodontal therapy reduced the incidence of peak levels of inflammatory markers. Antibiotics and further surgical therapy did not enhance the effect (Clinicaltrials.gov NCT02197260).

OBJECTIVES: To evaluate the morphological condylar changes following orthognathic surgery by using a rapid and reliable computational method on panoramic radiographs. METHODS: Digital panoramic radiographs of 45 patients who underwent bilateral sagittal split osteotomy (alone or associated with a Le Fort I osteotomy) between 2007 and 2010 were analysed. Calculation of the area, perimeter and height of 90 condyles was performed by using a specific computational method. Measurements were taken before surgery (m1), 1 day after surgery (m2) and 1 year after surgery (m3). The evolution of each index was analysed using paired t-tests between measures before and 1 day after surgery (m1 - m2) and measures before and 1 year after surgery (m1 - m3). The changes in the condylar area, perimeter and height were examined using the Bland and Altman plotting method. RESULTS: There were no statistically significant changes in the mean condylar area, perimeter or height between m1 and m2 or between m1 and m3. The Bland and Altman plots for each index showed that a very limited number of condyles increased or decreased in area, perimeter and/or height outside the boundaries of the measurement error. Given the impossibility for a condyle to increase in size, these results are considered to represent the limits of the computational method used. CONCLUSIONS: This study demonstrated that there were no significant morphological condylar changes at the 1-year follow-up following surgery and that the range of normality in condylar changes could be influenced by the methodology used.

OBJECTIVE: HIV-infected children have impaired antibody responses after exposure to certain antigens. Our aim was to determine whether HIV-infected children had lower varicella zoster virus (VZV) antibody levels compared with HIV-infected adults or healthy children and, if so, whether this was attributable to an impaired primary response, accelerated antibody loss, or failure to reactivate the memory VZV response. METHODS: In a prospective, cross-sectional and retrospective longitudinal study, we compared antibody responses, measured by enzyme-linked immunosorbent assay (ELISA), elicited by VZV infection in 97 HIV-infected children and 78 HIV-infected adults treated with antiretroviral therapy, followed over 10 years, and 97 age-matched healthy children. We also tested antibody avidity in HIV-infected and healthy children. RESULTS: Median anti-VZV immunoglobulin G (IgG) levels were lower in HIV-infected children than in adults (264 vs. 1535 IU/L; P<0.001) and levels became more frequently unprotective over time in the children [odds ratio (OR) 17.74; 95% confidence interval (CI) 4.36-72.25; P<0.001]. High HIV viral load was predictive of VZV antibody waning in HIV-infected children. Anti-VZV antibodies did not decline more rapidly in HIV-infected children than in adults. Antibody levels increased with age in healthy (P=0.004) but not in HIV-infected children. Thus, antibody levels were lower in HIV-infected than in healthy children (median 1151 IU/L; P<0.001). Antibody avidity was lower in HIV-infected than healthy children (P<0.001). A direct correlation between anti-VZV IgG level and avidity was present in HIV-infected children (P=0.001), but not in healthy children. CONCLUSION: Failure to maintain anti-VZV IgG levels in HIV-infected children results from failure to reactivate memory responses. Further studies are required to investigate long-term protection and the potential benefits of immunization.

BACKGROUND: Owing to methodological issues, little research has been conducted to examine quality of life (QoL) as a treatment outcome in autism spectrum disorders (ASD) and intellectual disabilities (ID). This study was conducted to combine QoL measures and objective observations of challenging behaviours (CB) in order to evaluate changes over time in adults with ASD and ID who were treated in two different residential programmes; we hypothesised that a decrease in CB would be related to an improved QoL. METHOD: In a longitudinal study (45 months), we followed 31 adults with ASD and ID who had been integrated into two residential programmes [Autism Programme with a Structured Method (PAMS) vs. traditional programme for ID (No-PAMS)] for 2-19 years. QoL [Quality of Life Inventory in a Residential Environment (IQVMR)] and severity of autistic features (Childhood Autism Rating Scales) were evaluated annually. CB, as measured by the Aberrant Behaviour Checklist (ABC), including stereotypic behaviour and inappropriate speech, were repeatedly assessed every 3 months. RESULTS: Observed separately, the groups' results were different. In the PAMS programme, stereotypic behaviour and inappropriate speech (ABC scores) significantly decreased, and the IQVMR total score increased; in contrast, in the comparison group, ABC scores did not change and the IQVMR total score decreased. In all, three mixed-effect ANCOVAs partially confirmed that the PAMS programme had an effect on CB and that QoL improvement did not directly depend on the type of programme but on reducing CB as measured by the ABC. CONCLUSION: The PAMS programme has a positive and indirect influence on QoL by reducing CB.

BACKGROUND: Incident reporting is a widely recommended method to measure undesirable events in anaesthesia. Under-utilization is a major weakness of voluntary incident reporting systems. Little is known about factors influencing reporting practices, particularly the clinical environment, anaesthesia team composition, severity of the incident, and perceived risk of litigation. The purpose of this study was to assess each of these, using an existing anaesthesia database. METHODS: We performed a retrospective cohort study and analysed 46 207 surgical patients. We used multivariate analysis to identify factors associated with the non-utilization of the reporting system. RESULTS: We found that in 7022 (15.1%) of the procedures performed, the incident reporting system was not used. Factors associated with the non-use of the system were regional anaesthesia/local anaesthesia, odds ratio (OR) 1.64 [95% confidence interval (CI) 1.03-2.62], emergency procedures OR 1.15 (95% CI: 1.05-1.27), and a consultant anaesthetist working without a trainee, OR 1.71 (95% CI: 1.03-2.82). In contrast, factors such as longer duration of surgery, OR 0.85 (95% CI: 0.76-0.94), the presence of a senior anaesthesia trainee, OR 0.86 (95% CI: 0.81-0.92), and the occurrence of severe complications with a high risk of litigation (i.e. death, nerve injuries) were less associated with a non-use of the reporting system, OR 0.65 (95% CI: 0.44-0.97). Team composition and time of day had no measurable impact on reporting practices. CONCLUSIONS: Clinical factors play a significant role in the utilization of an anaesthesia incident reporting system and more particularly, severity of complications and higher liability risks which appear more as incentives than barriers to incident reporting.

Odds ratios (ORs) and relative risks (RRs) are sensitive to the length of follow-up. In meta-analyses, pooling such results from studies with different lengths of follow-up may lead to an artificial heterogeneity and discrepancy caused by the choice of the summary index. In this article, we explore the utility of a meta-analysis method that uses the ratio of logarithms of survival probability as the measure of association, and that avoids the problems mentioned above when hazards are proportional. Meta-analyses of ORs, RRs and ratios of logarithms of survival probability are compared through a simulation study, in which data are simulated from a proportional hazard model and the length of follow-up varies across studies using realistic patterns of variability. Results show that the heterogeneity increases with the variability of length of follow-up for OR and RR, but not for the ratio of the logarithms of survival probability. A published meta-analysis is used to illustrate the method.
