Background: This meta-analysis evaluates the overall effect of the non-pharmacological intervention, aerobic exercise, upon serum liver enzymes levels, glucose metabolism and anthropometric measures amongst patients with metabolic associated fatty liver disease (MAFLD). It also examines whether the effects on these outcomes are moderated by the aerobic training protocol when considered according to the American College of Sports Medicine (ACSM) recommended FITT (frequency, intensity, time, type) principles. Approach and Results: Fifteen randomized control trials were included in the meta-analysis. Compared with usual care, continuous and interval training showed significant efficacy in alanine aminotransferase (ALT) level improvement (MD = −2.4, 95% CI: −4.34 to −0.46 p = 0.015, I² = 9.1%). Interventions based on all types of aerobic exercise protocols showed significant improvement of intrahepatic triglycerides (MD = −4.0557, 95% CI: −5.3711 to −2.7403, p < 0.0001, I² = 0%) and BMI (MD = −0.9774, 95% CI: −1.4086 to −0.5462, p < 0.0001, I² = 0). Meta-regression analysis demonstrated a significant correlation between total intervention time and ALT level (for all aerobic protocols: 6.0056, se = 2.6896, z = 2.2329, p = 0.02; as well as for continuous and interval aerobic protocols: 5.5069, se = 2.7315, z = 2.016, p = 0.04). Conclusions: All types of aerobic exercise protocols are effective at improving intrahepatic triglycerides and lead to a reduction in body mass index. In addition, continuous and interval aerobic exercise may be more effective at improving ALT ≤12 weeks intervention time benefits the management of MAFLD.

Background: The role of sensitization to inhalant allergens in atopic dermatitis (AD) in children is uncertain. The aim of our study was to assess the relationship of AD symptoms with sensitization to aeroallergens in Polish children ages 6‐7 and 13‐14 years. Material and Method: Epidemiology of Allergic Disorders in Poland is a randomized study with medical examination according to the ECRHS II and the International Study of Asthma and Allergies in Childhood standards in nine selected regions of Poland. We studied 6‐7-year-old (n = 4510) and 13‐14-year-old children (n = 4721). A total of 1583 children (25%) had a medical examination and a skin-prick test (SPT) with the 15 most common aeroallergens. Results: AD was diagnosed in 235 children (8.9%) (8.7%, 6‐7-year-old children; 9.0%, 13‐14-year-old children; 8.6% boys and 9.1% girls). AD was more frequent in urban versus rural habitants (9.6% versus 3.7%; p < 0.05) and in participants with a positive atopy history versus those without atopy (9.4% versus 5.1%; p < 0.05). Positive SPT was found in 1165 children (43.9%) (38.5% boys, 49.5% girls) and 64.72% with AD versus 41.9% without AD (p < 0.05) and more common in the rural region versus urban setting among 6‐7 year-olds (71.8% versus 35.0%; p < 0.05). The most frequent allergic reaction was Dermatophagoides pteronyssinus (13.5%), Dermatophagoides farina (11.7%), and grasses/crop plants (11.8%). The same pattern was seen in participants with and those without AD. Children with AD had more frequent positive SPT for all aeroallergens (p < 0.05). Conclusion: AD should be more frequent in children with a positive atopy history and in children who live in the city. Aeroallergens play an essential role in pathogenesis of eczema in children. House-dust mites and grass pollen proved to be the most common relevant aeroallergens.

We compared initial computed tomography (CT) and positron emission tomography (PET)/CT in 96 patients with Hodgkin lymphoma (HL), assessing the role of baseline PET/CT in stage migration and treatment selection. The number of patients with stage I, II, III and IV disease based on CT versus PET/CT was: 5 vs. 7, 49 vs. 37, 28 vs. 22 and 14 vs. 30, respectively. In 33 (34%) patients, PET/CT changed HL stage: 27 (28%) were upstaged and six (6.3%) downstaged. Upstaging was caused by detection of new extranodal involvements (47 sites in 26 patients): bone marrow (10 patients), spleen (five patients) and lung (two patients). In nine patients≥2 further coexisting locations were detected. Downstaging resulted from the absence of fluorodeoxyglucose (18F-FDG) uptake in enlarged nodes (>15 mm) in the abdomen and pelvis. PET/CT modified HL stage in 34% of patients leading to treatment modification in the majority. Our results indicate that PET/CT should be mandatory in the initial staging of HL.
