Burden of disease and lifestyle habits in adolescents and young adults prone to frequent episodic migraine: A secondary comparative analysis.

The objective of this study was to assess the burden of disease and prevalence of lifestyle factors for adolescents and young adults with frequent episodic migraine. We conducted a secondary comparative analysis of data collected during two previous studies. Inclusion criteria for this analysis were age 15-35 years, 15 to 44 migraine episodes within 12 weeks, and completeness of Migraine Disability Assessment and lifestyle questionnaire data. Datasets of 37 adults (median age [interquartile range]: 25 [6]) and 27 adolescents (median age [interquartile range]: 15 [1]) were analyzed. 81% (n = 30) of adults reported severe disability (16% [n = 3] of adolescents; p < 0.001). Headache frequency (24 vs. 17 days; p = 0.005) and prevalence of regular analgesic use (60% [n = 22] vs. 18% [n = 5]; p = 0.002) were significantly higher in adults. In adults, sleep duration on weekdays was significantly lower (8.5 vs. 10 h; p < 0.001). Any consumption of caffeine tended to be higher in adolescents and alcohol consumption tended to be higher in adults (p > 0.05). This study underlines the importance of educating adolescents and young adults with migraine about lifestyle habits that are likely to interfere with the condition.

A simple prognostic score based on troponin and presepsin for COVID-19 patients admitted to the emergency department: a single-center pilot study.

BACKGROUND: The need to determine prognostic factors that can predict a particularly severe or, conversely, the benign course of COVID-19 is particularly perceived in the Emergency Department (ED), considering the scarcity of resources for a conspicuous mass of patients. The aim of our study was to identify some predictors for 30-day mortality among some clinical, laboratory, and ultrasound variables in a COVID-19 patients population. METHODS: Prospective single-center pilot study conducted in an ED of a University Hospital. A consecutive sample of confirmed COVID-19 patients with acute respiratory failure was enrolled from March 8th to April 15th, 2020. RESULTS: 143 patients were enrolled. Deceased patients (n = 65) were older (81 vs. 61 years, p <0.001), and they had more frequently a history of heart disease, neurological disease, or chronic obstructive pulmonary disease (p-values = 0.026, 0.025, and 0.034, respectively) than survived patients. Troponin I and presepsin had a significant correlation with a worse outcome. Troponin achieved a sensitivity of 77% and a specificity of 82% for a cut-off value of 27.6 ng/L. The presepsin achieved a sensitivity of 54% and a specificity of 92% for a cut-off value of 871 pg/mL. CONCLUSION: In a population of COVID-19 patients with acute respiratory failure in an ED, presepsin and troponin I are accurate predictors of 30-day mortality. Presepsin is highly specific and could permit the early identification of patients who could benefit from more intensive care as soon as they enter the ED. Further validation studies are needed to confirm this result.

[Analysis of motor development within the first year of life: 3-D motion tracking without markers for early detection of developmental disorders]. / Analyse der Spontanmotorik im 1. Lebensjahr: Markerlose 3-D-Bewegungserfassung zur Früherkennung von Entwicklungsstörungen.

Children with motor development disorders benefit greatly from early interventions. An early diagnosis in pediatric preventive care (U2-U5) can be improved by automated screening. Current approaches to automated motion analysis, however, are expensive, require lots of technical support, and cannot be used in broad clinical application. Here we present an inexpensive, marker-free video analysis tool (KineMAT) for infants, which digitizes 3­D movements of the entire body over time allowing automated analysis in the future.Three-minute video sequences of spontaneously moving infants were recorded with a commercially available depth-imaging camera and aligned with a virtual infant body model (SMIL model). The virtual image generated allows any measurements to be carried out in 3­D with high precision. We demonstrate seven infants with different diagnoses. A selection of possible movement parameters was quantified and aligned with diagnosis-specific movement characteristics.KineMAT and the SMIL model allow reliable, three-dimensional measurements of spontaneous activity in infants with a very low error rate. Based on machine-learning algorithms, KineMAT can be trained to automatically recognize pathological spontaneous motor skills. It is inexpensive and easy to use and can be developed into a screening tool for preventive care for children.

Temporal processing deficit leads to impaired multisensory binding in schizophrenia.

INTRODUCTION: Schizophrenia has been characterised by neurodevelopmental dysconnectivity resulting in cognitive and perceptual dysmetria. Hence patients with schizophrenia may be impaired to detect the temporal relationship between stimuli in different sensory modalities. However, only a few studies described deficit in perception of temporally asynchronous multisensory stimuli in schizophrenia. METHODS: We examined the perceptual bias and the processing time of synchronous and delayed sounds in the streaming-bouncing illusion in 16 patients with schizophrenia and a matched control group of 18 participants. RESULTS: Equal for patients and controls, the synchronous sound biased the percept of two moving squares towards bouncing as opposed to the more frequent streaming percept in the condition without sound. In healthy controls, a delay of the sound presentation significantly reduced the bias and led to prolonged processing time whereas patients with schizophrenia did not differentiate between this condition and the condition with synchronous sound. CONCLUSION: Schizophrenia leads to a prolonged window of simultaneity for audiovisual stimuli. Therefore, temporal processing deficit in schizophrenia can lead to hyperintegration of temporally unmatched multisensory stimuli.

Attention and multisensory integration of emotions in schizophrenia.

The impairment of multisensory integration in schizophrenia is often explained by deficits of attentional selection. Emotion perception, however, does not always depend on attention because affective stimuli can capture attention automatically. In our study, we specify the role of attention in the multisensory perception of emotional stimuli in schizophrenia. We evaluated attention by interference between conflicting auditory and visual information in two multisensory paradigms in patients with schizophrenia and healthy participants. In the first paradigm, interference occurred between physical features of the dynamic auditory and visual stimuli. In the second paradigm, interference occurred between the emotional content of the auditory and visual stimuli, namely fearful and sad emotions. In patients with schizophrenia, the interference effect was observed in both paradigms. In contrast, in healthy participants, the interference occurred in the emotional paradigm only. These findings indicate that the information leakage between different modalities in patients with schizophrenia occurs at the perceptual level, which is intact in healthy participants. However, healthy participants can have problems with the separation of fearful and sad emotions similar to those of patients with schizophrenia.

Predictive value of early virological response to treatment with different interferon-based regimens plus ribavirin in patients with chronic hepatitis C.

Early virological response (EVR) to different interferon-based regimens plus ribavirin and its ability to predict the outcome of therapy in patients with chronic hepatitis C were investigated. The study design was as follows: 64 naive patients were considered, 32/64 received pegylated interferon alpha-2b (Peg-IFN-alpha2b) plus ribavirin and the remaining 32 received leucocyte interferon alpha (IFN-alpha) plus ribavirin. At week 4 of treatment, EVR was present in 68.7% and 37.5% of patients treated with Peg-IFN-alpha2b plus ribavirin, and with leucocyte interferon alpha (IFN-alpha) plus ribavirin, respectively (p = 0.024). At week 12, the cumulative EVR rates did not differ between the two groups (71.9% vs 56.2%, p >0.05) because a higher proportion of patients achieved EVR for the first time after more than 4 weeks of therapy in the standard IFN-alpha group. Sustained virological response (SVR) rates, however, resulted significantly higher in the Peg-IFN-alpha2b group (65.6% vs 37.5%; p = 0.045) since a higher proportion of patients who received standard IFN-alpha relapsed during the follow-up. In the standard IFN-alpha group, HCV genotype 1 (p = 0.035), high baseline viral load (p = 0.035) and the presence of bridging fibrosis/cirrhosis (p = 0.011) were closely associated with significantly lower SVR rates. In the Peg-IFN-alpha2b group, only bridging fibrosis/cirrhosis (p = 0.02) negatively influenced the outcome of treatment. Overall, 33/41 (80.5%) patients with EVR at week 12 were sustained responders, yielding a positive predictive value (PPV) of 0.80. However, when SVR was related to the time taken to reach EVR, 32/34 (94.1%) patients with EVR at week 4 of therapy (PPV = 0.94) versus 1/7 (14.3%) patients who had EVR after more than 4 weeks of therapy (PPV = 0.14) resulted sustained responders (p = 0.000057). In conclusion, EVR at week 4 of treatment is strongly associated with the likelihood of achieving SVR, regardless of the therapeutic regimen. However, when compared with standard IFN-alpha plus ribavirin, treatment with Peg-IFN-alpha2b plus ribavirin significantly increases the probability of viral clearance within the first 4 weeks of treatment. Finally, patients who do not clear the virus within the first 12 weeks of treatment have no chance of achieving SVR, justifying discontinuation of therapy in these patients.

[Multiple extrahepatic manifestations in a patient with chronic hepatitis C treated with interferon-alfa]. / Manifestazioni extraepatiche multiple in una paziente con epatite cronica C trattata con interferone-alfa.

The case of a 61-years-old female patient with chronic hepatitis C who developed multiple consecutive extrahepatic manifestations is reported. One of these manifestations (lichen planus) appeared before HCV-related chronic hepatitis was diagnosed and treated with interferon-alpha, suggesting that it was likely associated with HCV itself. Other manifestations appeared during IFN-alpha treatment (polyarthritis) or after the end of treatment (ulcerative cholitis, sarcoidosis) implying a role for either HCV or IFN-alpha treatment in the pathogenesis of extrahepatic manifestations.
