Abstract
Background In the COVID-19 era, we designed the webinar "COVID-19: instructions for use" with the aim of providing clear and actionable information to school staff about the characteristics of the disease, the preventive measures to adopt and the path for early detection and control of COVID-19 in primary schools of Modena province. Methods We performed a cross-sectional survey using a 7-item closed-ended satisfaction questionnaire self-administered to webinar participants among school staff of the Modena Municipality and neighbouring. Results A total of 103 out of 152 (68%) participants delivered the questionnaires. The participating staff came from 29 schools. Most of respondents (83.5%) were primary school teachers following by kindergarten teachers and educators. The overall webinar assessment index was "very good" for 51% of attendees and "good" for the remaining. Nevertheless, 25.2% highlighted the need to have more time dedicated to the discussion. Conclusions Our project promotes a virtuous circle between school-family and community; so that the benefits can be sustained and enhanced. This may improve the effectiveness of the preventive measures in terms of transmission of SARS-CoV-2 and other virus.

Abstract
Environmental enrichment may slow cognitive decay possibly acting through an improvement in vascular function. Aim of the study was to assess the effects of a 7-month cognitive, social, and physical training program on cognitive and vascular function in patients with mild cognitive impairment. In a single-center, randomized, parallel-group study, 113 patients (age, 65–89 years) were randomized to multidomain training (n=55) or usual care (n=58). All participants underwent neuropsychological tests and vascular evaluation, including brachial artery flow-mediated dilation, carotid–femoral pulse wave velocity, carotid distensibility, and assessment of circulating hematopoietic CD34+ and endothelial progenitor cells. At study entry, an age-matched control group (n=45) was also studied. Compared with controls, patients had at study entry a reduced flow-mediated dilation (2.97±2.14% versus 3.73±2.06%;
P
=0.03) and hyperemic stimulus (shear rate area under the curve, 19.1±15.7 versus 25.7±15.1×10
−3
;
P
=0.009); only the latter remained significant after adjustment for confounders (
P
=0.03). Training improved Alzheimer disease assessment scale cognitive (training, 14.0±4.8 to 13.1±5.5; nontraining, 12.1±3.9 to 13.2±4.8;
P
for interaction visit×training=0.02), flow-mediated dilation (2.82±2.19% to 3.40±1.81%, 3.05±2.08% to 2.24±1.59%;
P
=0.006;
P
=0.023 after adjustment for diameter and shear rate area under the curve), and circulating hematopoietic CD34
+
cells and prevented the decline in carotid distensibility (18.4±5.3 to 20.0±6.6, 23.9±11.0 to 19.5±7.1 Pa
−1
;
P
=0.005). The only clinical predictor of improvement of cognitive function after training was established hypertension. There was no correlation between changes in measures of cognitive and vascular function. In conclusion, a multidomain training program slows cognitive decline, especially in hypertensive individuals. This effect is accompanied by improved systemic endothelial function, mobilization of progenitor CD34
+
cells, and preserved carotid distensibility.

Abstract
We evaluated the analytical characteristics and clinical usefulness of a commercially available IRMA kit for measuring plasma concentrations of atrial natriuretic peptide (ANP) in healthy subjects and in patients with heart failure. The method uses two monoclonal antibodies prepared against sterically remote epitopes of the ANP molecule; the first antibody is coated on the solid-phase beads, and the second is radiolabeled with 125I. Fifty-nine healthy subjects and 77 patients with heart failure were studied. After subjects had rested 20 min in a recumbent position, blood samples were collected from a brachial vein into ice-chilled disposable polypropylene tubes containing aprotinin and EDTA. Plasma samples were immediately separated by centrifugation and stored at -20 degrees C until assay. The working range (CV <15%) was 10-2000 ng/L. The detection limit (2.13 +/- 0.91 ng/L) was similar to those reported for other IRMAs but was much better than those of RIAs. For healthy subjects, the results of this method (18.0 +/- 10.6 ng/L, range 4.7-63 ng/L, median 16.7 ng/L, n = 59) were similar to those generally reported for the most accurate methods, i.e., those using preliminary extraction and chromatographic purification of plasma samples. Measured plasma ANP was significantly associated with the severity of clinical symptoms, i.e., NYHA class (ANOVA, P <0.0001), and with the left ventricular ejection fraction (n = 62, r = 0.618, P <0.0001). Patients with severe heart failure showed greatly increased values (NYHA III-IV: 257.4 +/- 196.6 ng/L, n = 23).

Abstract
Patients with differentiated thyroid cancer (DTC) are conventionally followed with serial 131I whole-body scintigraphy (WBS) and serum thyroglobulin (hTg) assay. Given the 15%-20% incidence of discordant results, we developed a sensitive and specific procedure for monitoring such patients, based on the assumption that 131I uptake, even if too low to be detected by 131I WBS, could be assayed in serum as thyroid products (hTg, T3 and T4) endogenously labeled with 131I. Our study included 125 patients routinely monitored for tumor recurrence or for the persistence of functioning thyroid tissue after complete primary treatment for DTC (surgery and 131I ablation of remnants). A plasma sample, taken 72 hr after administering 131I for WBS was fractionated on a Sephadex-G25 superfine column by first eluting all of the radioactive species except the thyroid hormones and then the radioiodothyronines. The sensitivity and specificity of chromatography in detecting functioning thyroid tissue after primary treatment for DTC were 98.4% and 100% (accuracy 99.2%), respectively, versus 90.6% and 95.1% for 131I WBS (accuracy 92.8%) and 60.9% and 100% for hTg (accuracy 80%). Combining chromatography with serum hTg gave the highest gains in diagnostic performance (100% for all parameters). This chromatographic method can be used in addition to conventional procedures in the follow-up of patients with DTC and represents a highly sensitive test for assessing the results of 131I ablation of postsurgical remnants.

Abstract
A satisfactory definition of reverse 3,3',5'-triiodothyronine (rT3) kinetics in humans cannot be obtained if the plasma disappearance curve of the injected labeled hormone is the only experimental data available; most of the kinetic parameters can only be bounded within ranges showing unacceptable variabilities. To gain additional experimental data a double-tracer approach is proposed. After simultaneous injection of [125I]rT3 and 131I the following three experimental curves were determined in plasma: 1) the disappearance of [125I]rT3, 2) the disappearance of 131I, and 3) the appearance of 125I generated in vivo from labeled rT3 degradation. Combined analysis of these three curves, based on a complex six-compartment model, was developed and applied to data obtained in a group of normal subjects. Through this new analysis, fractional disposal rates and fractional exchange rates between the plasma compartment and the periphery are uniquely determined. The main physiologically interesting information on the degradation of the hormone that emerges from these studies are 1) all degradative pathways of rT3 generate iodide, being in all cases the [125I]rT3 dose completely recovered as 125I in plasma; and 2) most rT3 is degraded (65-90%) in peripheral tissues rapidly exchanging with the plasma pool. The extended experimental base is not yet sufficient to compute unique values for production rate (PR) and body mass (Qt); the validity of estimates of PR and Qt is based on the assumption that injected [125I]rT3 is able to trace all rT3 peripherally produced (from thyroxine). The new approach yields ranges for PR and Qt (1.12-2.15 micrograms/h and 2.88-8.24 micrograms) much narrower than those computable from the [125I]rT3 disappearance curve only (1.12-5.07 micrograms/h for PR and 2.88-23.7 micrograms for Qt).

Abstract
14 diabetic boys (five with a family history of diabetes and nine without) and 29 "short normal" boys were studied. A gonadal function test (2.000 IU of hCG i.m. for 3 days and plasma testosterone assay before and after the hCG administration) as well as an LH-RH test (50 microgram i.v.) were carried out. While basal testosterone level turned out to be similar in the two groups of children, it was significantly lower (p less than 0.01) after hCG than the mean value of the control group. This difference was mainly observed in those patients with a family history of diabetes. In the diabetic children, basal LH level was normal and the pituitary LH reserve was lower than in the control group. Both basal FSH level and FSH pituitary reserve were lower than in normal children. These data show that an alteration in the hypothalamus-pituitary-gonadal function is already evident in the diabetic child.
