The impact of COVID-19 pandemic on the Emergency Room and Orthopedic Departments in Piacenza: a retrospective analysis.

INTRODUCTION AND AIM: The Coronavirus pandemic represents one of the most massive health emergencies in the last century. Aim of the study is to evaluate the trend of E.R. accesses and orthopaedic events during the pandemic of Covid-19. MATERIALS AND METHODS: we retrospectively analysed all data related to patients admitted to the E.R. Department of the Hospital of Piacenza from August 26th 2019 to August 23rd 2020, splitting this period on February 23rd 2020. RESULTS: Our analysis shows a reduction of -18.0% in E.R. accesses. We calculated a growth of deaths in the E.R. equal to +220%. Our orthopaedic pathway recorded a drop of -26.8%. Traumas occurred at home increased (+19.1%). We note an actual drop only on proximal femur fractures (weighted average of -17.7%), while all the others underwent an increase. DISCUSSION: The amount of E.R. accesses registered a drop -18.0%, while the pathway dedicated to emergency cases underwent an increase. The major complexity of clinical conditions influenced the number of hospitalizations and the fear of the infection increased hospitalization refusals. There has been a zeroing of school traumas, a reduction in sport, transfer home-work/work-home, work, roadside, injuries. Total amount of fractures strongly increase after the end of the lockdown. CONCLUSION: our data confirmed the decrease of retirement houses, sports, works and roadsides traumas and a zeroing of schools ones, while those occurred inside domestic environment underwent a consistent raise. We noticed a reduction in femur fractures and significant spread of all fractures after the end of the lockdown.

Determination of Deoxynivalenol Biomarkers in Italian Urine Samples.

Deoxynivalenol (DON) is a mycotoxin mainly produced by Fusariumgraminearum that can contaminate cereals and cereal-based foodstuff. Urinary DON levels can be used as biomarker for exposure assessment purposes. This study assessed urinary DON concentrations in Italian volunteers recruited by age group, namely children, adolescents, adults, and the elderly. In addition, vulnerable groups, namely vegetarians and pregnant women, were included in the study. To determine the urinary DON, its glucuronide and de-epoxydated (DOM-1) forms, an indirect analytical approach was used, measuring free DON and total DON (as sum of free and glucuronides forms), before and after enzymatic treatment, respectively. Morning urine samples were collected on two consecutive days, from six different population groups, namely children, adolescent, adults, elderly, vegetarians and pregnant women. Total DON was measured in the 76% of the collected samples with the maximum incidences in children and adolescent age group. Urine samples from children and adolescent also showed the highest total DON levels, up to 17.0 ng/mgcreat. Pregnant women had the lowest positive samples per category (40% for day 1 and 43% for day 2, respectively), low mean levels of total DON (down to 2.84 ng/mgcreat) and median equal to 0 ng/mgcreat. Estimation of DON dietary intake reveals that 7.5% of the total population exceeds the TDI of 1 µg/kg bw/day set for DON, with children showing 40% of individuals surpassing this value (male, day 2).

Role of mycotoxins in the pathobiology of autism: A first evidence.

Objectives: Gene-environment interaction is an emerging hypothesis to expound not only the autism pathogenesis but also the increased incidence of neurodevelopmental disorders (such as autistic spectrum disorder, attention-deficit, hyperactivity disorder). Among xenobiotics, mycotoxins are worldwide contaminants of food that provoke toxicological effects, crucially resembling several symptoms associated with autism such as oxidative stress, intestinal permeability, and inflammation. Here, we focused on a group of mycotoxins to test their role in the manifestation of autism, try to explain their mechanism of action, and discuss possible preventive and therapeutic interventions. Methods: Autistic children (n = 52) and healthy children [n = 58 (31 siblings and 27 unrelated subjects)] were recruited and body fluids and clinical data collected. The diagnosis of autism was made according to DSM V criteria, then with GMDS 0-2, WPPSI, and ADOS. Ochratoxin A (OTA), gliotoxin, zearalenone, and sphingosine/sphinganine ratio were determined by LC analysis in sera and urines. Statistical analysis was performed by the Wilcoxon Rank Sum (Mann-Whitney) test and Spearman test. Results: By comparing the results of autistic patients with those of unrelated controls, a significant association was found for OTA levels in urines (P = 0.0002) and sera (P = 0.0017), and also comparing patients with siblings and unrelated controls together (P = 0.0081). Discussion: Our results are the first describing a possible role of OTA in the pathobiology of autism. Recalling the male prevalence of ASD (male/female = 4-5/1), it is noted that, in animal models, OTA exerts its neurotoxicity especially in males. Moreover, in vitro, OTA increases microRNA-132 that is dysregulated in autistic patients and involved in reciprocal regulation of the autism-related genes MeCP2 and PTEN. A personalized diet coupled with probiotic administration, especially OTA adsorbing Lactobacillus, could ameliorate autistic symptoms in OTA-positive patients.

Occurrence of deoxynivalenol in an elderly cohort in the UK: a biomonitoring approach.

Deoxynivalenol (DON) is a Fusarium toxin, to which humans are frequently exposed via diet. Although the elderly are speculated to be sensitive to the toxic effects of DON as a result of age-related conditions, disease and altered DON metabolism, there is lack of available data on DON biomarkers in this age group. This study characterised urinary DON concentrations and its metabolites in elderly aged ≥65years (n = 20) residing in Hull, UK. Morning urinary specimens were collected over two consecutive days together with food records to assess dietary intake over a 24h-period prior to each urinary collection. Free DON (un-metabolised), total DON (sum of free DON and DON-glucuronides or DON-GlcA) and de-epoxy deoxynivalenol (DOM-1) were analysed using a validated LC-MS/MS methodology. Total DON above the limit of quantification 0.25 ng/mL was detected in the urine from 90% of elderly men and women on both days. Mean total DON concentrations on day 1 were not different from those on day 2 (elderly men, day 1: 22.2 ± 26.3 ng/mg creatinine (creat), day 2: 28.0 ± 34.4 ng/mg creat, p = 0.95; elderly women, day 1: 22.4 ± 14.6 ng/mg creat, day 2: 29.1 ± 22.8 ng/mg creat, p = 0.58). Free DON and DON-GlcA were detected in 60-70% and 90% of total urine samples, respectively. DOM-1 was absent from all samples; the LoQ for DOM-1 was 0.50 ng/mL. Estimated dietary intake of DON suggested that 10% of the elderly exceeded the maximum provisional tolerable daily intake for DON. In this single-site, UK-based cohort, elderly were frequently exposed to DON, although mean total DON concentrations were reported at moderate levels. Future larger studies are required to investigate DON exposure in elderly from different regions of the UK, but also from different counties worldwide.

Assessment of Urinary Deoxynivalenol Biomarkers in UK Children and Adolescents.

Deoxynivalenol (DON), the mycotoxin produced mainly by Fusarium graminearum and found in contaminated cereal-based foodstuff, has been consistently detected in body fluids in adults. Available data in children and adolescents are scarce. This study assessed urinary DON concentrations in children aged 3-9 years (n = 40) and adolescents aged 10-17 years (n = 39) in the UK. Morning urine samples were collected over two consecutive days and analysed for free DON (un-metabolised form), DON-glucuronides (DON-GlcA), deepoxy deoxynivalenol (DOM-1), and total DON (sum of free DON, DON-GlcA, and DOM-1). Total DON was detected in the urine of >95% of children and adolescents on both days. Mean total DON concentrations (ng/mg creatinine) were 41.6 and 21.0 for children and adolescents, respectively. The greatest total DON levels were obtained in female children on both days (214 and 219 ng/mg creatinine on days 1 and 2, respectively). Free DON and DON-GlcA were detected in most urine specimens, whereas DOM-1 was not present in any sample. Estimation of dietary DON exposure suggested that 33-63% of children and 5-46% of adolescents exceeded current guidance regarding the maximum provisional tolerable daily intake (PMTDI) for DON. Although moderate mean urinary DON concentrations were shown, the high detection frequency of urinary DON, the maximum biomarker concentrations, and estimated dietary DON exposure are concerning.

Study on the Association among Mycotoxins and other Variables in Children with Autism.

Environmental factors and genetic susceptibility are implicated in the increased risk of autism spectrum disorder (ASD). Mycotoxins are agricultural contaminants of fungal origin that represent real risk factors for human health and especially for children. Thus, the main hypothesis of this work is that the deterioration of the clinical manifestation of autism in children may result from the exposure to mycotoxins through the consumption of contaminated food. Within a cross-sectional study, a group of autistic children (n = 172) and a group of controls (n = 61) (siblings and non-parental) were recruited in North and South Italy. All children had blood and urine samples taken, for testing some mycotoxins by a LC-MS/MS validated method. Blood samples were also tested for assessing specific IgG against food and fungal antigens and cytokines. The analyses outputs highlighted statistically significant differences comparing mycotoxins levels between (i) children groups both in urine (deoxynivalenol and de-epoxydeoxynivalenol, p = 0.0141 and p = 0.0259, respectively) and serum (aflatoxin M1, ochratoxin A and fumonisin B1, p = 0.0072, p = 0.0141 and p = 0.0061, respectively); (ii) a group of selected fungal IgGs, and IgGs against wheat and gluten and (iii) cytokines. These results suggest the need for a deeper examination of the role that mycotoxins may have on the etiology of ASD.

Prevalence of overweight and obesity among school-aged children in urban, rural and mountain areas of the Veneto Region, Italy.

OBJECTIVE: To define the prevalence of overweight and obesity among school-aged children resident in mountain areas, rural areas and urban areas. DESIGN, SETTING AND SUBJECTS: The sample (n = 12832; 50.7% boys) included 9- and 11-year-old children of the Veneto Region of north-east Italy. Overweight and obesity status were determined using the International Obesity Task Force cut-off points for body mass index. The prevalence of overweight and obese subjects was calculated with a confidence interval of 95%. The Mantel-Haenszel method was used to compare the combined prevalence of overweight and obesity among children resident in mountain areas, rural areas and urban areas. RESULTS: Among boys the prevalence of overweight was 21.06%, while obesity prevalence was 5.92%; among girls overweight prevalence was 21.30%, while obesity prevalence was 5.15%. The prevalence was higher among 11-year-old boys (odds ratio (OR) = 1.19; 95% confidence interval (CI): 1.06-1.33) and 9-year-old girls (OR = 1.13; 95% CI: 1.01-1.26). Children resident in rural areas presented a higher risk of overweight and obesity compared with children resident in mountain areas (Mantel-Haenszel OR = 1.27; 95% CI: 1.13-1.42; chi2 = 17.55; P < 0.0001) and in urban areas (Mantel-Haenszel OR = 1.18; 95% CI: 1.07-1.31; chi2 = 10.39; P < 0.001). CONCLUSIONS: A relevant prevalence of overweight and obesity was found; the excess weight concerns one child in four. There are differences linked to different geographical areas that must be further investigated.

[Evaluation of the quality of care provided by the 118 system: questionnaire on the perceived quality of emergency care]. / Valutazione della qualità assistenziale offerta dal sistema 118: questionario sulla qualità percepita del soccorso.

UNLABELLED: Patients' satisfaction is an important element of quality of care. Only few studies assessed patients satisfaction during emergency care. AIM: The aim of this study was to assess the patients' perception of the quality of care during emergencies and their satisfaction of the patient-nurse interaction. POPULATION: Stratified sample of 280 patients cared for by ambulance services between October and December 2002. Patients with red codes were excluded. METHODS: Two focus groups, one with nurses and one with citizens, were organised to identify items relevant for patients' satisfaction. A 14 items questionnaire was designed to explore 3 areas; quality of interpersonal care, efficiency and comfort; technical area. Patients were interviewed by phone and asked to express their level of agreement with each item (1 no agreement-5 perfect agreement). RESULTS: 272 patients (97.1%) answered the questionnaire. The technical area (effectiveness of treatment and waiting time) and efficiency-comfort (information by phone, comfort of the chair-stretcher, waiting times for the call) reported a high-very high satisfaction (74.3 and 72.2) while the satisfaction for the quality of the interpersonal care (information on treatments, reassurance, respect of the significant persons) was lower, 67.6%. CONCLUSION: Patients are able to distinguish several dimensions of care. The satisfaction is higher for the technical components of care thus leaving space for improvement of interpersonal care during emergencies.
