This is a booming field, evidenced by the date of the publications found. However, most publications use data from a very limited number of patients, which presents an obstacle to deep learning models training. Although the performance of the models has achieved very satisfactory results, there is still room for improvement, and there is arguably a long way before these models can be used safely and effectively in clinical practice.Non-suicidal self-injury (NSSI) is a considerable health problem among adolescents. Affect regulation by means of self-injury may promote the maintenance of NSSI. However, existing findings have limited ecological validity. The present study aimed to assess emotional and interpersonal states preceding and following incidents of NSSI in female adolescents. Adolescents with NSSI-disorder completed ecological momentary assessments of affective and interpersonal states on an hourly basis for multiple days. Multilevel mixed-effect regression analyses were conducted to assess antecedences and consequences of acts of self-injury. Data from n = 73 female adolescents covering a total of 52 acts of self-injury were available for analyses. The urge to self-injure on the between subject-level and negative affect on the within-level were best predictors of self-injury. Surprisingly, self-injury increased negative affect and decreased feelings of attachment (mother only) in the following hour. In line with findings in adults, results illustrate the important association between negative affect and self-injury in female adolescents. However, the occurrence of NSSI itself was related to concurrent increases in negative affect, and even prospectively predicted a consecutive increase in negative affect. Therefore, improvements of negative affect following (or during) self-injury, as previously reported, are at best short-lived ( less then 1 h).
The aim of the present study was to compare in terms of pain perception the use of conventional anesthesia and a computerized system.
Forty patients in need for extractions, dental restorative, or periodontal treatment bilaterally, were selected. Each patient served as his/her own control being subjected to two anesthesia techniques conventional and electronically controlled anesthesia with Calaject® (Rønvig Dental MFG, Daugaard, Denmark). Each patient received both treatments in a blind way 1week apart. The order was previously randomized. After performing the anesthesia (upper dental nerve, palatal posterior nerve, or inferior alveolar nerve), the patients evaluated their pain sensation with a visual analogue scale (VAS) (0-10). After treatment, the patients were asked about the presence of pain during the procedure. Finally, the patients selected their preference between the conventional and electronic anesthesia technique. Differences in assessment of pain's injection were analyzed using the Wilcoxon test and the Kruskal-Wallis test (α = 0.05).
The mean general pain experienced was 3.73 (1.55 SD) for the conventional anesthesia, and 1.95 (0.53 SD) for computerized anesthesia. Statistical differences (p < 0.05) were found. There was no difference between the treatments (p value = 0.061). Most patients did not feel any pain during the treatment. Finally, 92.5% of the patients preferred the electronic system.
Computerized anesthesia system produces significantly less pain compared with a conventional anesthesia syringe. Although both obtained sufficient anesthetic depth to perform treatments, the majority of patients chose electronic anesthesia as the most satisfactory.
Computerized anesthesia devices are valid and more comfortable alternative to conventional anesthesia.

(1) To determine whether healthy humans can distinguish between the intensity and unpleasantness of exertional dyspnoea; (2) to evaluate the reliability of qualitative dyspnoea descriptors during exercise; and (3) to assess the reliability of the Multidimensional Dyspnoea Profile (MDP) METHODS Forty-four healthy participants (24M20F, 25 ± 5years) completed maximal incremental cycling tests on three visits. During visit 1, participants rated the intensity and unpleasantness of dyspnoea simultaneously throughout exercise using the modified 0-10 category-ratio Borg scale. On visits 2 and 3, participants rated either the intensity or unpleasantness of dyspnoea alone at the same measurement times as visit 1. On all visits, participants selected qualitative descriptors throughout all exercise intensities from a list of 4, selected relevant qualitative descriptors from a list of 15 at peak exercise, and completed the MDP.
Participants rated their dyspnoea intensity significantly higher for a given minute ventilation ([Formula see text]) compared to dyspnoea unpleasantness (dyspnoea-[Formula see text] slope 0.08 ± 0.02 vs. 0.07 ± 0.03 Borg 0-10/Lmin
, p < 0.001) during visit 1. The onset of intensity ratings occurred at a significantly lower work rate compared to unpleasantness ratings measured on the same exercise test (52 ± 41 vs. 91 ± 53 watts, p < 0.001). Dyspnoea intensity and unpleasantness remained significantly different for a given ventilation even when measured independently on separate exercise tests (p < 0.05). There was good-to-excellent reliability (ICC > 0.60) for the use of qualitative dyspnoea descriptors and the MDP to measure dyspnoea at peak exercise.
Exercise-induced dyspnoea in healthy adults can differ in the sensory and affective dimensions, and can be measured reliably using qualitative descriptors and the MDP.

Premature birth is associated with lasting effects, including lower exercise capacity and pulmonary function, and is acknowledged as a risk factor for cardiovascular disease. The aim was to evaluate factors affecting exercise capacity in adolescents born preterm, including the cardiovascular and pulmonary responses to exercise, activity level and strength.
21 preterm-born and 20 term-born adolescents (age 12-14years) underwent strength and maximal exercise testing with thoracic bioimpedance monitoring. Baseline variables were compared between groups and ANCOVA was used to compare heart rate, cardiac output (Q) and stroke volume (SV) during exercise between groups while adjusting for body surface area.
Preterm-borns had lower maximal aerobic capacity than term-borns (2.0 ± 0.5 vs. 2.5 ± 0.5 L/min, p = 0.01) and lower maximal power (124 ± 26 vs. 153 ± 33 watts, p < 0.01), despite similar physical activity scores. Pulmonary function and muscular strength did not differ significantly. BMH-21 cell line Although baseline Q and SV did not differ between groups, preterm adolescents had significantly lower cardiac index (Qi) at 50, 75 and 100% of maximal time to exhaustion, driven by SV volume index (SVi, 50% max time 53.
