Abstract Background Inhibitory control and attention processing atypicalities are implicated in various diseases, including autism spectrum disorders (ASD). These cognitive functions can be tested by using visually guided saccade-based paradigms in children, adolescents and adults to determine the time course of such disorders. Methods In this study, using Gap, Step, Overlap and Antisaccade tasks, we analyzed the oculomotor behavior of 82 children, teenagers and adults with high functioning ASD and their peer typically developing (TD) controls in a two-year follow-up study under the auspices of the InFoR-Autism project. Analysis of correlations between oculomotors task measurements and diagnostic assessment of attentional (ADHD-RS and ADHD comorbidity indices) and executive functioning (BRIEF scales) were conducted in order to evaluate their relationship with the oculomotor performance of participants with ASD. Results As indicated by the presence of a Gap and Overlap effects in all age groups, the oculomotor performances of ASD participants showed a preserved capability in overt attention switching. In contrast, the difference in performances of ASD participants in the Antisaccade task, compared to their TD peers, indicated an atypical development of inhibition and executive functions. From correlation analysis between our oculomotor data and ADHD comorbidity index, and scores of attention and executive function difficulties, our findings support the hypothesis that a specific dysfunction of inhibition skills occurs in ASD participants that is independent of the presence of ADHD comorbidity. Limitations These include the relatively small sample size of the ASD group over the study’s two-year period, the absence of an ADHD-only control group and the evaluation of a TD control group solely at the study’s inception. Conclusions Children and teenagers with ASD have greater difficulty in attention switching and inhibiting prepotent stimuli. Adults with ASD can overcome these difficulties, but, similar to teenagers and children with ASD, they make more erroneous and anticipatory saccades and display a greater trial-to-trial variability in all oculomotor tasks compared to their peers. Our results are indicative of a developmental delay in the maturation of executive and attentional functioning in ASD and of a specific impairment in inhibitory control.

Abstract In CN-AML, mutations of specific genes have prognostic significance and are used for treatment guidance. However, these mutations are in general not mutually exclusive and CN-AML patients (pts) frequently harbor mutational combinations with unclear prognostic significance because of the concurrent presence of mutations with favorable (CEBPA, NPM1) and unfavorable (ASXL1, DNMT3A, IDH1, IDH2, FLT3-ITD, MLL-PTD, RUNX1, TET2, WT1) impact on outcome. Here, we report the frequency and clinical significance of isolated mutations and their combinations in 364 CN-AML pts. Younger [<60 years (y); n=163] and older (≥60 y; n=201) pts were intensively treated on frontline CALGB/Alliance protocols and, per protocol, did not undergo allogeneic stem cell transplantation in first complete remission (CR). Median follow-up for pts alive was 8.7 y. Pts were analyzed centrally for mutations in the ASXL1, CEBPA, DNMT3A, IDH1, IDH2, NPM1, RUNX1, TET2, and WT1 genes and the presence of FLT3-ITD, FLT3-TKD and MLL-PTD. We found that 99% of pts had ≥1 and 88% ≥2 of the 12 mutations. Specifically, 11% of pts had 1 gene mutated (n1), 40% had 2 (n2), 31% 3 (n3), and 18% harbored ≥4 mutated genes (n4). The distribution of the different n groups in younger and older pts was similar (Fig 1). The expected frequency of each mutated gene in every numerical (n) group was calculated as follows: [no. of pts with the mutated gene] x [total no. of mutations in the n group] / [total no. of mutations in all pts], and compared with the observed frequency. CEBPA, IDH2, NPM1, and RUNX1 mutations were overrepresented in the n1 and n2 groups (P<.001, P<.001, P=.002, P=.02, respectively) and thus likely represent “early” events in leukemogenesis. In contrast, DNMT3A, FLT3-ITD, and TET2 mutations were more frequent in the n3 and n4 groups (P=.008, P<.001, P=.02, respectively) suggesting that they are likely “late” events. The distribution among age groups and clinical impact of the “early” mutations (i.e., CEBPA, NPM1, IDH2) presenting as isolated mutations or in combination with other mutations were then investigated. Isolated RUNX1 mutations could not be evaluated due to small sample size. Younger pts were more likely to harbor an isolated “early” mutated gene than older pts (21% v 12%, P=.03). Specifically, isolated CEBPA and NPM1 mutations were more frequent in younger pts compared with the older (7% v 2%, P=.007; 7% v 3%, P=.07, respectively). In pts with isolated CEBPA mutations, these were always bi-allelic. Single “early” mutated genes varied in their impact on CR achievement (CEBPA: 100%, NPM1: 94%, IDH2: 67%), and overall survival (OS; 3-y OS: CEBPA: 87%, NPM1: 69%, IDH2: 22%). Acquisition of additional mutations adversely modified the prognostic significance of favorable “early” mutations in the CEBPA (Fig 2A) and NPM1 (Fig 2B) genes, but left unchanged the unfavorable effect of IDH2 mutations (Fig 2C). Two mutational combinations were exceptions to this: younger pts with both NPM1 and DNMT3A mutations (8 pts) had an excellent prognosis with 3-y OS of 100%; and older pts with concurrent NPM1 and IDH2 mutations (9 pts; all IDH2 mutations were in codon R140) had a high 3-y OS rate of 67%. We conclude that CEBPA and NPM1 mutations mainly define pts with favorable prognosis when they present as single markers, whereas mutated IDH2 predominantly associates with adverse outcome. The NPM1+DNMT3A and NPM1+IDH2 mutational patterns may define novel favorable molecular subtypes in younger and older CN-AML pts, respectively, but these results require corroboration in larger pt cohorts.

BACKGROUND New technologies can promote knowledge of HIV infection among patients suffering from this disease. Older patients with HIV infection represent an increasingly large group that could benefit from the use of specific apps. OBJECTIVE The aim of the study was to observe the acceptability and use of a mobile app on HIV infection in patients at least 60 years old and offer them the possibility of anonymously establishing contact with their peers. METHODS A series of clinical and psychosocial parameters were studied in 30 HIV-infected patients of over 60 years. The patients must be at least 60 years old, with a follow-up in the outpatient clinic for at least 1 year and without pathologies that limit his or her life expectancy to less than a year. They must know how to read and write. To be part of the group assigned to the app, they had to have their own smartphone and confirm that they were connected to the internet from that device. Overall, 15 of them were randomized to use an app and 15 were in the control group. All tests were repeated after 6 months. RESULTS The median age of patients was 66.5 years. Among them, 29 patients had an undetectable viral load at baseline. The median number of comorbid diseases was 2. Overall, 11 of them lived with their partners and 19 lived alone. They spent an average of 5 hours a day sitting down, and 56% (17/30) of them referred high physical activity. They scored 4 out of 5 for general quality of life perception. Moreover, 80% (24/30) presented high adherence to their treatment, and the average number of concomitant medications was 5. In the 6-min walking test, they covered a distance of 400 meters, and 3 of them desaturated during the test. The 15 patients made frequent use of the app, with 2407 sessions and an average of 7 min and 56 seconds time of use with a total of 13,143 screen views. During the 6 months of the trial, 3 non-AIDS events took place. There were no significant modifications to body mass index, blood pressure measurements, lipid profile, or immuno-virology information data. There were no differences in the questionnaire scores for perception of quality of life, confessed physical activity, or antiretroviral treatment (ART) and non-ART treatment adherence. CONCLUSIONS Significant differences between studied parameters were not objectified in these patients, possibly because this trial has significant limitations, such as a small sample size and only a brief follow-up period. However, patients did use the app frequently, making this a possible intervention to be proposed in future subsequent studies.

The difficulties with motor skills in children with autism spectrum disorders (ASD) has become a major focus of interest. Our objectives were to provide an overall profile of motor capacities in children with ASD compared to neurotypically developed children through specific tests, and to identify which motor tests best discriminate children with or without ASD. Twenty-two male children with ASD (ASD—10.7 ± 1.3 years) and twenty controls (CONT—10.0 ± 1.6 years) completed an evaluation with 42 motor tests from European Physical Fitness Test Battery (EUROFIT), the Physical and Neurological Exam for Subtle Signs (PANESS) and the Movement Assessment Battery for Children ( M-ABC). However, it was challenging to design a single global classifier to integrate all these features for effective classification due to the issue of small sample size. To this end, we proposed a hierarchical ensemble classification method to combine multilevel classifiers by gradually integrating a large number of features from different motor assessments. In the ASD group, flexibility, explosive power and strength scores (p < 0.01) were significantly lower compared to the control group. Our results also showed significant difficulties in children with ASD for dexterity and ball skills (p < 0.001). The principal component analysis and agglomerative hierarchical cluster analysis allowed for the classification of children based on motor tests, correctly distinguishing clusters between children with and without motor impairments.

Purpose – The purpose of this paper is to investigate the feasibility of telephone follow-up (TFU) after uncomplicated cataract surgery in low-risk patients and patient satisfaction with this alternative clinical pathway. Design/methodology/approach – Prospective, non-randomised cohort study. A ten-point subjective ophthalmic assessment questionnaire and a six-point patient satisfaction questionnaire were administered to patients following routine cataract surgery at two to three weeks post-procedure. All patients were offered a further clinic review if required. Exclusion criteria comprised ophthalmic co-morbidities, hearing/language impairment and high risk of post-operative complications. Patient notes were retrospectively reviewed over the study period to ensure no additional emergency attendances took place. Findings – Over three months, 50 eyes of 50 patients (mean age: 80; age range 60-91; 66 per cent second eye surgery) underwent uncomplicated phacoemulsification surgery received a TFU at 12-24 days (mean: 16 days) post-operatively. Subjective visual acuity was graded as good by 92 per cent of patients; 72 per cent patients reported no pain and 20 per cent reported mild occasional grittiness. Patient satisfaction was graded 8.9 out of 10; 81.6 per cent defined TFU as convenient and 75.5 per cent of patients preferred TFU to routine outpatient review. No additional visits were required. Research limitations/implications – Non-randomised with no control group; small sample size. One patient was unable to be contacted. Practical implications – Post-operative TFU can be suitably targeted to low-risk patients following uncomplicated cataract surgery. This study demonstrated a high patient satisfaction. A larger, randomised study is in progress to assess this further. Originality/value – This is the first study reporting TFU results and patient satisfaction to the usual alternative two-week outpatient review.

Background: There is little evidence on the use of intralesional triamcinolone (ILT) for managing fistulous tracts in hidradenitis suppurativa (HS). Objective: To assess the clinical and ultrasound response to ILT for single fistulous lesions in HS patients. Methods: A prospective open-label study was conducted to assess response to ILT (40 mg/mL) for fistulous tracts in HS. Consecutive patients (Hurley II stage exclusively) presenting to our department were recruited from August 2016 to August 2018. They received a single injection of ILT as the sole treatment. Lesions were assessed clinically and by ultrasound at baseline and 90 days. Results: Of the 53 included HS patients with fistulous tracts, 36 (67.9%) were women, 30 (56.6%) were smokers, and 36 (67.9%) were obese or overweight (body mass index ≥25). Median Sartorius score was 9.0 (IQR 9.0–36.0), and median duration of the lesion treated was 6 months (IQR 3.0–12.0). Fistulous tracts were injected with 0.5 mL triamcinolone 40 mg/mL. Seven patients were lost to follow-up. At 90 days, 20 (43.5%) lesions showed clinical and ultrasound resolution, 13 (28.3%) showed only clinical resolution while persisting on ultrasound, and 13 (28.3%) persisted both clinically and on ultrasound. Mean clinical size decreased from 17.0 to 5.1 mm (p < 0.0001), while mean length on ultrasound decreased from 16.0 to 8.6 mm (p < 0.0001). Limitations: Small sample size and no control group. Conclusions: Our study suggests that ILT is beneficial for small fistulous tracts in HS.

Adolescents with high-functioning autism spectrum disorders (ASDs) are at high risk for developing psychiatric symptoms, with anxiety disorders among the most commonly cooccurring. Cognitive behavior therapies (CBTs) are considered the best practice for treating anxiety in the general population. Modified CBT approaches for youth with high-functioning ASD and anxiety have resulted in significant reductions in anxiety following intervention. The purpose of the present study was to develop an intervention for treating anxiety in adolescents with ASD based on a CBT program designed for school-aged children. The Facing Your Fears-Adolescent Version (FYF-A) program was developed; feasibility and acceptability data were obtained, along with initial efficacy of the intervention. Twenty-four adolescents, aged 13–18, completed the FYF-A intervention. Results indicated significant reductions in anxiety severity and interference posttreatment, with low rates of anxiety maintained at 3-month follow-up. In addition, nearly 46% of teen participants met criteria for a positive treatment response on primary diagnosis following the intervention. Initial findings from the current study are encouraging and suggest that modified group CBT for adolescents with high-functioning ASD may be effective in reducing anxiety symptoms. Limitations include small sample size and lack of control group. Future directions are discussed.

Abstract Background Treatment with eculizumab in Shiga toxin–associated haemolytic and uraemic syndrome (STEC-HUS) remains controversial despite its increasing utilization. The aim of our study was to evaluate the outcomes of children treated with eculizumab for STEC-HUS in a single-centre matched cohort study. Methods Data were retrospectively collected from medical records of children diagnosed with STEC-HUS. The outcomes of patients treated with eculizumab for STEC-HUS were compared with those of a control group of untreated patients matched for age, sex and severity of acute kidney injury with a 1:2 matching scheme. Results Eighteen children (median age 40.6 months) with STEC-HUS treated with eculizumab were compared with 36 matched control patients (median age 36.4 months) who did not receive eculizumab. All patients survived in the two groups. Within 1 month of HUS onset, the evolution of haematological and renal parameters did not differ between the two groups. At 12 months of follow-up, renal outcome was not significantly different between the two groups. At the last follow-up, the prevalence of decreased glomerular filtration rate in the eculizumab group (27%) was not statistically different from that in controls (38%), as was the prevalence of proteinuria and high blood pressure. Children who received eculizumab more often had extrarenal sequelae during follow-up. Eculizumab treatment appeared to be safe in children with STEC-HUS. Conclusion The benefit of eculizumab on renal and extrarenal outcomes in STEC-HUS could not be established based on our findings. However, efficacy and safety are not best assessed by the observational design and small sample size of our study. Randomized controlled trials are thus required to determine the efficacy of eculizumab in this indication.

AbstractThe improvement or acquisition of socioemotional skills contributes to the academic and personal adaptation of university students. The way students think about themselves and others influence their social skills and well-being. Considering the importance of social competence for professional practice in the face of new social realities, the university must invest in programs that promote the socio-emotional development of students. This study compared the effects of interventions based on Rational Emotive Behavior Therapy and Psychoeducation on assertive skills and subjective well-being. This study involved 25 undergraduate students of a public university. The students were randomly allocated to three groups, including the Control group, and they were evaluated by means of questionnaires, inventories, scales, and written evaluation of the group process. The program consisted of 10 meetings and a 6-week follow-up. Irrational beliefs were reduced and their assertive skills’ scores increased in the post-intervention and follow-up evaluations, regardless of the group. Only verbal reports from participants indicated an increase in well-being. The students’ written reports after the end of the meetings indicate that the two forms of intervention were evaluated as promoting change by the students. One of the limitations of the study is the size of the groups. Despite the very small sample size, the study highlights that developing a set of flexible beliefs is fundamental to the exercise of assertiveness.

Abstract The incidence of myopia in adolescents is gradually increasing, and orthokeratology has achieved effective effects in controlling the progress of myopia, but the effects are mixed. The retrospective study included 30 monocular orthokeratology (ortho-k) lens-treated adolescents to explore the true effectiveness of ortho-k lenses and 36 binocular ortho-k lenses-treated adolescents to study the influencing factors of ortho-k lenses. After 12 months, among 30 adolescents treated with monocular ortho-k lenses, the average axial elongation in the ortho-k group was significantly less than that in the control group (P = 0.002). After 24 months, among 36 adolescents treated binocular ortho-k lenses, the axial elongation in the different initial age groups and different initial myopia groups were significantly different (all P < 0.05). Axial elongation correlated negatively with initial myopia during follow-up periods. In adolescents with myopia, axial elongation can be controlled effectively using an ortho-k lens. Younger children with initial higher myopia will benefit more than older children with initial lower myopia.

AbstractObjectivesEstablished reference intervals of thyroid function in neonates are important; however, studies often consist of a small sample size or lack of clinical information. We aim to define reference intervals for thyroid-stimulating hormone (TSH) and free thyroxine (FT4) for infants aged 14–30 days. We also reviewed follow-up TSH for infants with initial values 10–20 mIU/L.MethodsVenous TSH and FT4 of term babies aged 14–30 days with breast milk jaundice that had thyroid function test performed as part of a prolonged jaundice workout from September 2016 to March 2017 were analyzed. Electronic medical records were reviewed to ensure only well babies with no pathological causes of jaundice or conditions that may affect thyroid function were included. TSH and FT4 were analyzed using immunoassay analyzer Dxl 800, Beckman Coulter.ResultsThere were no correlations between FT4 and TSH with gender, birth weight and ethnicity. Correlation coefficient between FT4 and total bilirubin was weak at 0.138 (p=0.001). No association was found between TSH and bilirubin levels. Mean FT4 was higher in the younger age group day 14–21 (p<0.01). There was no significant difference in TSH values between the age groups. Infants with mildly elevated TSH 10–20 mIU/L had normalized values on follow-up (mean, 11.41 vs. 4.42 mIU/L; p<0.01; 95%CI, 5.88–8.09). The following reference intervals (2.5–97.5th percentile) were derived: FT4 day 14–21 (n=513): 11.59–21.00 pmoL/L; FT4 day 22–30 (n=66): 10.14–19.60 pmoL/L; TSH day 14–30 (n=579): 1.90–10.34 mIU/L. Comparison between studies showed variations of reference intervals with different manufacturer assays, age and methodology.ConclusionsOur reference intervals would be useful in the clinical setting. Infants with mildly elevated TSH could be monitored first instead of immediate treatment.
