Sensory Processing Difficulties Correlate With Disease Severity and Quality of Life Among Children With Migraine

Introduction: Headaches are common among children and about 80% of children reporting them. Migraine and tension type headaches are the most common primary headaches in children and the prevalence of migraine is about 8%. Accompanying sensory symptoms are common before, during and after migraine attacks. They may be a part of a wider symptom constellation called sensory processing disorder or difficulties (SPD). This includes both hyper or hypo sensitivity to sensations. However, the literature regarding sensory processing symptoms of children and youth with headaches as well as its interaction with child's emotional aspects and quality of life is scarce.Materials and Methods: One hundred and thirty-four children between the ages of 8 and 12 participated in this study. Fifty-four children (22 boys and 32 girls) with episodic migraine were prospectively recruited from pediatric neurological clinics during the years 2014–2017. The control group included 80 healthy children. Both groups completed a health and demographic questionnaire, headache assessment including Ped-MIDAS, Short Sensory Profile, State-Trait Anxiety Inventory (STAI) for children, and the Pediatric Quality of Life Inventory.Results: Children with migraine showed significantly higher prevalence of sensory processing difficulties and lower quality of life compared to healthy controls. Among children with migraine, sensory processing difficulties significantly correlated with lower quality of life. Headache-related disability and sensory processing difficulties predicted quality of life.Conclusion: The possible relationship between migraine and sensory processing disorder or difficulties stresses the need to screen for sensory processing difficulties among children with migraine and when found—refer to their impacts on children's daily function and quality of life

SLACC: Simion-based Language Agnostic Code Clones

Successful cross-language clone detection could enable researchers and developers to create robust language migration tools, facilitate learning additional programming languages once one is mastered, and promote reuse of code snippets over a broader codebase. However, identifying cross-language clones presents special challenges to the clone detection problem. A lack of common underlying representation between arbitrary languages means detecting clones requires one of the following solutions: 1) a static analysis framework replicated across each targeted language with annotations matching language features across all languages, or 2) a dynamic analysis framework that detects clones based on runtime behavior. In this work, we demonstrate the feasibility of the latter solution, a dynamic analysis approach called SLACC for cross-language clone detection. Like prior clone detection techniques, we use input/output behavior to match clones, though we overcome limitations of prior work by amplifying the number of inputs and covering more data types; and as a result, achieve better clusters than prior attempts. Since clusters are generated based on input/output behavior, SLACC supports cross-language clone detection. As an added challenge, we target a static typed language, Java, and a dynamic typed language, Python. Compared to HitoshiIO, a recent clone detection tool for Java, SLACC retrieves 6 times as many clusters and has higher precision (86.7% vs. 30.7%). This is the first work to perform clone detection for dynamic typed languages (precision = 87.3%) and the first to perform clone detection across languages that lack a common underlying representation (precision = 94.1%). It provides a first step towards the larger goal of scalable language migration tools.Comment: 11 Pages, 3 Figures, Accepted at ICSE 2020 technical trac

Doxycycline desensitization in chronic Q fever—A critical tool for the clinician

We present the case of a 45 year old woman with acute Q fever pneumonia who progressed to the chronic phase of the disease despite azithromycin therapy. A trial of doxycycline was halted because of severe allergy and she was put on clarithromycin and later moxifloxacin. Failure of both drugs required desensitization to doxycycline with escalating doses. After two-year treatment with doxycycline-hydroxychloroquine combination, complete recovery was declared. Our case highlights the option of doxycycline desensitization when an acute allergic reaction poses an obstacle to optimal treatment

Antiviral Treatment Down-Regulates Peripheral B-Cell CD81 Expression and CD5 Expansion in Chronic Hepatitis C Virus Infection

Hepatitis C virus (HCV) infection is associated with immune-mediated abnormalities and B-cell lymphoproliferation. Recently, CD81 was identified as an HCV receptor on B lymphocytes, providing a mechanism by which B cells are infected and activated by the virus. It has recently been shown that peripheral B-cell CD81 overexpression and CD5(+) subpopulation expansion correlate with HCV viral load and are associated with the development of HCV-related autoimmunity. In the present study, we assessed the effects of combination antiviral therapy (alfa interferon and ribavirin) on peripheral B-cell CD81 expression and CD5 expansion and the presence of autoimmune markers. Peripheral B-cell CD5 expression and the mean fluorescence intensity of CD81 were assessed by flow cytometry before and after treatment in 15 HCV-infected patients, in 10 untreated patients, and in 25 healthy controls. A significant posttreatment decrease in peripheral B-cell CD81 expression and disappearance of CD5(+) B-cell expansion were observed in all nine patients in whom a complete and sustained virological response was achieved (P < 0.01) (comparable to those for healthy controls). The decrease in CD81 overexpression and CD5 expansion in these patients was associated with a decrease and/or disappearance of autoimmune markers. In contrast, in nonresponders overexpression of CD81 and expansion of the CD5(+) B-cell subpopulation were not significantly changed and were comparable to those for untreated patients. In conclusion, antiviral therapy down-regulates peripheral B-cell CD81 expression and the CD5(+) population, either directly or by its effect on HCV RNA load. The overexpression of CD81 and the expansion of the population of CD5(+) peripheral B cells in HCV-infected patients may possibly play a role in the development of HCV-associated autoimmunity and lymphoproliferation

COVID-19 Lockdown in Israel: The Environmental Effect on Ultrafine Particle Content in the Airway

Inhaled ultrafine particle (UFP) content in exhaled breath condensate (EBC) was observed as an airway inflammatory marker and an indicator of exposure to particulate matter (PM). The exceptional decline in air pollution during the COVID-19 lockdown was an opportunity to evaluate the effect of environmental changes on UFP airway content. We collected EBC samples from 30 healthy subjects during the first lockdown due to COVID-19 in Israel (March&ndash;April 2020) and compared them to EBC samples retrieved during April&ndash;June 2016 from 25 other healthy subjects (controls) living in the same northern Israeli district. All participants underwent EBC collection and blood sampling. Ambient air pollutant levels were collected from the Israeli Ministry of Environmental Protection&rsquo;s online database. Data were acquired from the monitoring station closest to each subject&rsquo;s home address, and means were calculated for a duration of 1 month preceding EBC collection. UFP contents were measured in the EBC and blood samples by means of the NanoSight LM20 system. There was a dramatic reduction in NO, NO2, SO2, and O3 levels during lockdown compared to a similar period in 2016 (by 61%, 26%, 50%, and 45%, respectively). The specific NO2 levels were 8.3 ppb for the lockdown group and 11.2 ppb for the controls (p = 0.01). The lockdown group had higher UFP concentrations in EBC and lower UFP concentrations in serum compared to controls (0.58 &times; 108/mL and 4.3 &times; 108/mL vs. 0.43 &times; 108/mL and 6.7 &times; 108/mL, p = 0.05 and p = 0.03, respectively). In this observational study, reduced levels of air pollution during the COVID-19 lockdown were reflected in increased levels of UFP airway contents. The suggested mechanism is that low airway inflammation levels during lockdown resulted in a decreased UFP translocation to serum. Further studies are needed to confirm this hypothesis
