Abstract
PURPOSE Objective of this study was to assess the association between testosterone (T) levels and biochemical markers in a cohort of female patients admitted for SARS-CoV-2 infection in a respiratory intensive care unit (RICU). METHODS A consecutive series of 17 women affected by SARSCoV-2 pneumonia and recovered in the RICU of the Hospital of Mantua were analyzed. Biochemical inflammatory markers as well as total testosterone (TT), calculated free T (cFT), sex hormone-binding globulin (SHBG), and luteinizing hormone (LH) were determined. RESULTS TT and cFT were significantly and positively associated with PCT, CRP, and fibrinogen as well as with a worse hospital course. We did not observe any significant association between TT and cFT with LH; conversely, both TT and cFT showed a positive correlation with cortisol. By LOWESS analysis, a linear relationship could be assumed for CRP and fibrinogen, while a threshold effect was apparent in the relationship between TT and procalcitonin, LDH and ferritin. When the TT threshold value of 1 nmol/L was used, significant associations between TT and PCT, LDH or ferritin were observed for values above this value. For LDH and ferritin, this was confirmed also in an age-adjusted model. Similar results were found for the association of cFT with the inflammatory markers with a threshold effect towards LDH and ferritin with increased LDH and ferritin levels for values above cFT 5 pmol/L. Cortisol is associated with serum inflammatory markers with similar trends observed for TT; conversely, the relationship between LH and inflammatory markers had different trends. CONCLUSION Opposite to men, in women with SARS-CoV-2 pneumonia, higher TT and cFT are associated with a stronger inflammatory status, probably related to adrenal cortex hyperactivity.

Abstract
Resistive switching (RS) devices based on self-assembled nanowires (NWs) and nanorods (NRs) represent a fascinating alternative to conventional devices with thin film structure. The high surface-to-volume ratio may indeed provide the possibility of modulating their functionalities through surface effects. However, devices based on NWs usually suffer from low resistive switching performances in terms of operating voltages, endurance and retention capabilities. In this work, we report on the resistive switching behaviour of ZnO NW arrays, grown by hydrothermal synthesis, that exhibit stable, bipolar resistive switching characterized by SET/RESET voltages lower than 3 V, endurance higher than 1100 cycles and resistance state retention of more than 105 s. The physical mechanism underlying these RS performances can be ascribed to nanoionic processes involving the formation/rupture of conductive paths assisted by oxygen-related species in the ZnO active layer. The reported results represent, to the best of our knowledge, the best resistive switching performances observed in ZnO NW arrays in terms of endurance and retention.

Abstract
The extreme vulnerability of humans to new and old pathogens is constantly highlighted by unbound outbreaks of epidemics. This vulnerability is both direct, producing illness in humans (dengue, malaria), and also indirect, affecting its supplies (bird and swine flu, Pierce disease, and olive quick decline syndrome). In most cases, the pathogens responsible for an illness spread through vectors. In general, disease evolution may be an uncontrollable propagation or a transient outbreak with limited diffusion. This depends on the physiological parameters of hosts and vectors (susceptibility to the illness, virulence, chronicity of the disease, lifetime of the vectors, etc.). In this perspective and with these motivations, we analyzed a stochastic lattice model able to capture the critical behavior of such epidemics over a limited time horizon and with a finite amount of resources. The model exhibits a critical line of transition that separates spreading and non-spreading phases. The critical line is studied with new analytical methods and direct simulations. Critical exponents are found to be the same as those of dynamical percolation.

Abstract
BACKGROUND Several maternal anthropometric markers have been associated with the metabolic syndrome (MS) in offspring. The objectives of this study were (1) to determine the association between children's MS and maternal anthropometric markers such as body mass index (BMI), waist circumference (WC), WC/height, weight/sitting height squared, and WC/sitting height and (2) to compare the abilities of these five indices to identify children with MS. METHODS Data were collected cross-sectionally from five elementary schools between April 2007 and March 2008. BMI, WC, WC/height, weight/sitting height squared, and WC/sitting height were acquired in mothers and their children. Tanner stage, blood pressure, glucose, lipids, and insulin were measured in children. Criteria analogous to Adult Treatment Panel III for MS were used for children. RESULTS Of 624 children (307 boys) 8.96 +/- 1.86 years old, with their mothers being 36.25 +/- 7.14 years old, examined, 107 (17.1%) of children were obese (BMI >95th percentile per Centers for Disease Control and Prevention norms), and 95 (15.2%) were overweight (OW) (85th percentile < or =BMI < 95th percentile). Of the mothers, 109 (30.4%) were obese (BMI > 30 kg/m(2)), and 206 (33.0%) were OW (25 kg/m(2) < BMI < 30 kg/m(2)). Approximately 68% of the children were prepubertal. The prevalence of MS was 3.5% overall: 6.7% in OW and 13.9% in obese children. To determine which marker was a better predictor for MS, a receiver operating characteristics (ROC) curve was generated for the five maternal anthropometric measures, with children's MS as the dichotomous variable. The areas under the ROC curves were 0.697 +/- 0.07 for BMI, 0.698 +/- 0.07 for WC, 0.717 +/- 0.07 for WC/height, 0.725 +/- 0.07 for WC/sitting height, and 0.704 +/- 0.07 for weight/sitting height squared. There was no significant difference between the areas of the five maternal anthropometric markers as predictors of children's MS. CONCLUSIONS Measurement of maternal sitting height had no advantages over total height in the prediction of children's MS. All maternal anthropometric measures identified the MS in their children consistent with known familial associations of obesity and type 2 diabetes.

Abstract
We study a model of strongly correlated fermions in one dimension with extended N = 2 supersymmetry. The model is related to the spin S = 1/2 XXZ Heisenberg chain at anisotropy Delta = -1/2 with a real magnetic field on the boundary. We exploit the combinatorial properties of the ground state to determine its exact wave function on finite lattices with up to 30 sites. We compute several correlation functions of the fermionic and spin fields. We discuss the continuum limit by constructing lattice observables with well defined finite-size scaling behavior. For the fermionic model with periodic boundary conditions we give the emptiness formation probability in closed form.

Abstract
Whole lung lavage (WLL) is still the gold-standard therapy for pulmonary alveolar proteinosis (PAP). The few studies on the duration of the effect of WLL, belonging to a rather remote period, show significant but transient benefits. In 21 patients with idiopathic PAP, the duration of any benefit and, in 16 of them, the time course of lung function improvement (at baseline, 1 week, 6 months, 1 yr and then every 2 yrs after WLL) were evaluated. The present WLL technique takes longer, is invasively monitored and partially modified with respect to past techniques. More than 70% of patients remained free from recurrent PAP at 7 yrs. The bulk of the improvement in spirometric results was almost completely gained in the immediate post-WLL period due to the efficient clearance of the alveoli. At a median of 5 yrs, recovery of diffusing capacity of the lung for carbon monoxide was incomplete (75 +/- 19% of the predicted value) and there were residual gas exchange abnormalities (alveolar to arterial oxygen tension difference 3.6 +/- 1.5 kPa (27 +/- 11 mmHg)) and exercise limitation, probably explained by engorgement of lymphatic vessels. In conclusion, whole lung lavage for idiopathic pulmonary alveolar proteinosis is currently a safe procedure in an experienced setting, and provides long-lasting benefits in the majority of patients.

Abstract
The Global Initiative for Chronic Obstructive Lung Disease (GOLD) guidelines underline that the presence of chronic cough and sputum production before airflow obstruction offers a unique opportunity to identify subjects at risk of chronic obstructive pulmonary disease for an early intervention. Current epidemiological data on these subjects are scant. Between 1998-2000, the authors evaluated the prevalence and characteristics of these symptoms by a multicentre cross-sectional survey of Italian people aged between 20-44 yrs from the general population (Italian Study on Asthma in Young Adults (ISAYA)). Besides the questions on asthma, more than 18,000 subjects answered the question: "Have you had cough and phlegm on most days for as much as 3 months per year and for at least two successive years?" The adjusted prevalence of subjects with chronic cough and phlegm was 11.9%, being 11.8% in males and 12.0% in females. From these subjects approximately 20% reported coexisting asthma and approximately 30%, predominately females, were nonsmokers. The survey showed that sex (female), smoking and low socioeconomic status were significantly and independently associated with chronic cough and phlegm, current smoking playing the major role. The prevalence of subjects with chronic cough and phlegm is startlingly high among young adults. Further follow-up studies are needed to establish how many of them will go on to develop chronic obstructive pulmonary disease.

Abstract
Genetic factors are believed to play a role in the individual susceptibility to chronic obstructive pulmonary disease (COPD). Tumour necrosis factor (TNF) family genes have been widely investigated but inconsistent results may lie either in the genetic heterogeneity of populations or in the poor phenotype definition. A genetic study was performed using a narrower phenotype of COPD. The authors studied 86 healthy smokers and 63 COPD subjects who were enrolled based on irreversible airflow obstruction (forced expiratory volume in one second/forced vital capacity <70% predicted) and a diffusing capacity for carbon monoxide <50% predicted (moderate-to-severe COPD associated with pulmonary emphysema). The following polymorphisms were investigated: TNF-308, the biallelic polymorphism located in the first intron of the lymphotoxin-alpha gene, and exon 1 and exon 6 of the TNF receptor 1 and 2 genes, respectively. No significant deviations were found concerning the four polymorphisms studied between the two populations. The authors confirm that the tumour necrosis factor family genes, at least for the polymorphisms investigated, are not major genetic risk factors for chronic obstructive pulmonary disease in Caucasians, either defined in terms of emphysema (this study) or airflow obstruction (previous studies). Nevertheless, the authors would like to emphasise the importance of narrowing the phenotype in the search for genetic risk factors in chronic obstructive pulmonary disease.

Abstract
BACKGROUND Chronic thromboembolic pulmonary hypertension (CTEPH) can be successfully treated surgically by pulmonary thromboendarterectomy (PTE) but there are few data on mid-term cardiopulmonary function, particularly on exertion, and clinical benefits following pulmonary PTE. METHODS A 2 year follow up study was undertaken of clinical status, haemodynamic and lung function indices, gas exchange, and exercise tolerance in 38 patients of mean (SD) age 50 (15) years who had undergone PTE. RESULTS In-hospital mortality was about 10%. Before PTE all the patients were severely impaired (NYHA classes III-IV). There was no time difference in the improvement in the parameters: nearly all the improvement in cardiac output, gas exchange, and clinical status was achieved in the first 3 months as a result of the relief of pulmonary obstruction. At 3 months the percentage of patients with normal cardiac output and PaO(2) and of those with reduced clinical impairment increased to 97%, 59%, and 87%, respectively, without any further change. Only mean pulmonary artery pressure (mPAP), carbon monoxide transfer factor (TLCO), and exercise tolerance improved gradually during the second year, probably due to the recovery of the damaged small vessels. TLCO was overestimated before PTE but afterwards the trend was similar to that of mPAP. CONCLUSIONS At mid term only a few patients did not have a satisfactory recovery because of lack of operative success, hypertension relapse, or the effect of preoperative hypertension on vessels in non-obstructed segments. Most of the patients, even the more compromised ones, had excellent long lasting results.

Abstract
STUDY OBJECTIVES To evaluate early and late lung function abnormalities and their predictors in a large sample of children who underwent bone marrow transplantation (BMT) for leukemias in the 1990s, highlighting changes with respect to the 1980s. DESIGNS Prospective cohort. SETTING A university department of pediatrics. PARTICIPANTS Seventy-five consecutive children who underwent BMT were enrolled in the study (median age, 11 years; range, 6 to 19 years; 45 male and 30 female children). Twenty-three children received autologous BMT, and 52 children received allogeneic BMT; 50 children completed the study. MEASUREMENTS Clinical examinations and lung function tests were performed before BMT, and 3 to 6 months, 12 months, and 24 months after BMT. RESULTS Before BMT, at 3 to 6 months after BMT, and at 24 months after BMT, 44%, 85%, and 62% of children, respectively, had altered lung function in the absence of persistent respiratory symptoms. Between 3 months and 6 months after BMT, a restrictive pattern was the most frequent abnormality. The only predictive factors for late abnormalities were transplantation performed in the advanced disease phase (odds ratio [OR], 6.75; p = 0.005) and bronchopulmonary infections (OR, 3.9; p < 0.05). CONCLUSIONS These data suggest that a significant proportion of children who undergo BMT, especially if for leukemia in advanced phase, have early and late pulmonary abnormalities. These abnormalities, especially the late ones, seem to be more severe than patients reported in studies analyzing children undergoing BMT in the 1980s. This could be due to the more intensive front-line treatment protocols employed for treatment of children with acute leukemia in the 1990s.

Abstract
STUDY OBJECTIVES To assess (1) the possibility of predicting long-term postoperative lung function, and (2) the usefulness of maximal oxygen consumption (O(2)max) as a criterion for operability and as a predictor of long-term disability. DESIGN Prospective study. SETTING Outpatients and inpatients of a university hospital. PARTICIPANTS Sixty-two consecutive patients (mean +/- SD age, 62 +/- 8 years; 51 male and 11 female patients) were preoperatively evaluated for lung cancer resection (pneumonectomy or bilobectomy [n = 14] and lobectomy [n = 48]). MEASUREMENTS Clinical examination and recorded respiratory symptoms and spirometry results before surgery and 6 months after surgery. If predicted postoperative FEV(1) (ppoFEV(1)) was < 40%, patients underwent exercise testing; if O(2)max was between 10 mL/kg/min and 20 mL/kg/min, patients underwent a split-function study. RESULTS All the patients with ppoFEV(1) > or = 40%-even those patients (26%) with FEV(1) < 80%-underwent thoracotomy without further tests. Seven patients with ppoFEV(1) < 40% underwent exercise testing, and three of them underwent a split-function study. Nine patients (15%; including six patients with COPD and one patient with asthma) had immediate postoperative complications (pneumonia [n = 5] and respiratory failure [n = 4]); seven of these patients had ppoFEV(1) > or = 40%. ppoFEV(1) significantly underestimated the actual postoperative FEV(1) (poFEV(1); p < 0.001) 6 months after pneumonectomy or bilobectomy but was reliable for actual poFEV(1) after lobectomy. Two patients with predicted postoperative O(2)max > 10 mL/kg/min became oxygen dependent and had marked limitation of daily living. CONCLUSIONS ppoFEV(1) > or = 40% reliably identifies patients not requiring further tests and not at long-term risk of respiratory disability. O(2)max, effective for defining the immediate surgical risk, is not useful in predicting long-term disability.

Pulmonary toxicity is a well-recognized side effect of many ALL treatments. DESIGN Cross-sectional study conducted at least 3 years after cessation of therapy. SETTING Outpatient pneumology department of the University Hospital. PATIENTS Forty-four subjects (age range at observation, 6 to 23 years): 21 treated only with intensive Berlin-Frankfurt-Munster (BFM)-type chemotherapy for newly diagnosed ALL (group A), and 23 treated with chemotherapy plus BMT (group B). MEASUREMENTS A detailed history of smoking habit, respiratory symptoms, and diseases was recorded directly from the patients with the aid of their parents. A complete physical examination and lung function testing (lung volumes and diffusion capacity for carbon monoxide [DLCO]) were performed in all subjects. RESULTS No patient reported acute or chronic respiratory symptoms or diseases. In group A patients, lung function was in the normal range, except for three subjects in whom there was an isolated impairment of DLCO. In group B patients, lung function was markedly impaired, with more than half the patients having an abnormal DLCO. A statistically significant difference was found between the two groups for FVC (p = 0.022) and DLCO (p = 0.004). CONCLUSIONS Intensive, BFM-type frontline chemotherapy is not associated with late pulmonary dysfunction; however, retreatment including BMT can frequently injure the lung. Thus, in patients who undergo BMT and whose life expectancy is long, careful monitoring of lung function and counseling about avoiding additional lung risk factors is recommended.

Abstract
alpha 1-antitrypsin (AAT) deficiency is an inherited condition characterized by low serum levels of AAT and an increased risk of developing pulmonary emphysema. The disease occurs mainly in Caucasians, but Southern Europe, including Italy, is considered a low prevalence area. We developed a national program in Italy in order to improve our knowledge of the epidemiology of AAT deficiency and to establish a registry of the AAT-deficient individuals. The program had two phases: the first lasted 36 months, during which blood from coupons mailed by respiratory physicians from throughout the country, was isoelectrofocused by the Central Laboratory in Rome. The second phase started in February 1996, and the Registry was established. Up to August 1998, 151 subjects with AAT deficiency have been identified and 64 have been enrolled in the Registry. We believe that such a program plays a crucial role in identifying AAT deficiency in a country such as Italy, with low prevalence and low awareness of this rare condition.
