RESUMO
Background: Hip fracture injury is one of the principal health problems affecting the elderly. Patients reporting hip fractures often show relevant comorbidities leading to prolonged hospital stay, significant complications and higher mortality rates. This study aims to assess the risk factors associated with prolonged hospitalization after hip fracture, in-hospital mortality and transfers to other facilities. Study design: Retrospective cross-sectional study. Methods: The study considered all admissions performed between 2006 and 2015 in Abruzzo region, Italy. Logistic regression analyses were performed to evaluate odds ratios for each risk factor as predictor of in-hospital mortality, length of stay, and transfer to other facilities. Results: Age over 85 (OR=5.38) and cancer (OR=3.62) were identified as the strongest risk predictors for in hospital mortality; diabetes (OR=2.24) and heart failure (OR=1.57) were identified as predictors of prolonged length of stay and age over 85 (OR=1.38) and atrial fibrillation (OR=1.69) were identified as predictors of transfer to other facilities. Conclusions: With the rising incidence of hip fractures, identification of modifiable factors may help to reduce morbidity and mortality.

OBJECTIVE: To assess predictors of recurrence following laparoscopic radical hysterectomy (LRH) for apparent early stage cervical cancer (CC). METHODS: This is a retrospective multi-institutional study reviewing data of consecutive patients who underwent LRH for FIGO 2009 stage IA1 (with lymphovascular space invasion (LVSI)), IA2 and IB1(≤4 cm) CC, between January 2006 and December 2017. The following histotypes were included: squamous, adenosquamous, and adenocarcinoma. Multivariable models were used to estimate adjusted odds ratio (OR) and corresponding 95% CI. Factors influencing disease-free survival (DFS) and disease-specific survival (DSS) were also explored. RESULTS: 428 patients were included in the analysis. With a median follow-up of 56 months (1-162) 54 patients recurred (12.6%). At multivariable analysis, tumor size (OR:1.04, 95%CI:1.01-1.09, p = .02), and presence of cervical residual tumor at final pathology (OR: 5.29, 95%CI:1.34-20.76, p = .02) were found as predictors of recurrence; conversely preoperative conization reduced the risk (OR:0.32, 95%CI:0.11-0.90, p = .03). These predictors remained significant also in the IB1 subgroup: tumor size: OR:1.05, 95%CI:1.01-1.09, p = .01; residual tumor at final pathology: OR: 6.26, 95%CI:1.58-24.83, p = .01; preoperative conization: OR:0.33, 95%CI:0.12-0.95, p = .04. Preoperative conization (HR: 0.29, 95%CI: 0.13-0.91; p = .03) and the presence of residual tumor on the cervix at the time of surgery (HR: 8.89; 95%CI: 1.39-17.23; p = .01) independently correlated with DFS. No independent factors were associated with DSS. CONCLUSIONS: In women with early stage CC the presence of high-volume disease at time of surgery represent an independent predictor of recurrence after LRH. Conversely, preoperative conization and the absence of residual disease at the time of surgery might play a protective role.

BACKGROUND: Several social, economic and political factors have contributed to the global spread of alcohol and other drugs. Drug addiction represents a huge expense for the society in terms of direct and indirect health and social consequences, as it is associated with numerous medical issues such as HIV, other infections and psychiatric disturbances. OBJECTIVES: The aim of this study was the assessment of the hospital admissions among drug addicted patients in Abruzzo Region, central Italy, from 2006 to 2015, in order to clarify the specific causes of hospitalization. METHODS: Data were collected from all hospital discharge records, taking into account only the hospital discharge registrations coded 304 (drug dependence). Multivariate logistic regression was performed to evaluate factors associated with main causes of the admission. RESULTS: Between 2006 and 2015, an amount of 2,159 drug-addicted subjects, aged 38.0±9.7 years, were admitted to hospital. Most of the admissions occurred in public hospitals (2,039, 94.4%), through the emergency room access (1,503, 69.6%) From an amount of 2,159 hospitalizations, 1,178 (54.6%) were first and 981 (45.4%) were subsequent admissions. The most frequent cause of hospitalization was "Psychosis" (419, 19.4%). The trend by range of age showed a progressive reduction in hospital admissions for patients aged < 45 y. Further, an increase in the hospitalization rate was estimated over recent years among drug addict subjects aged 25-45 years. Cannabis consumption was associated with mental disorder admissions (OR: 3.16, p<0.001), opioid consumption was associated with hepatic disorder admission (OR:2.16, p<0.001) and cardiovascular admissions (OR: 1,78, p<0.001), and cocaine was associated with cardiovascular admissions (OR:1,55, p:<0.001). CONCLUSIONS: Mental disorders result to be the leading cause of hospitalization among drug-addicts, principally associated with cannabis abuse. Opioid and cocaine abuse was associated with hepatic and cardiovascular disorders.

We study in real time the optical response of individual plasmonic nanoparticles on a mirror, utilized as electrodes in an electrochemical cell when a voltage is applied. In this geometry, Au nanoparticles are separated from a bulk Au film by an ultrathin molecular spacer. The nanoscale plasmonic hotspot underneath the nanoparticles locally reveals the modified charge on the Au surface and changes in the polarizability of the molecular spacer. Dark-field and Raman spectroscopy performed on the same nanoparticle show our ability to exploit isolated plasmonic junctions to track the dynamics of nanoelectrochemistry. Enhancements in Raman emission and blue-shifts at a negative potential show the ability to shift electrons within the gap molecules.
RESUMO
We study the optical response of individual nm-wide plasmonic nanocavities using a nanoparticle-on-mirror design utilised as an electrode in an electrochemical cell. In this geometry Au nanoparticles are separated from a bulk Au film by an ultrathin molecular spacer, giving intense and stable Raman amplification of 100 molecules. Modulation of the plasmonic spectra and the SERS response is observed with an applied voltage under a variety of electrolytes. Different scenarios are discussed to untangle the various mechanisms that can be involved in the electronic interaction between NPs and electrode surfaces.
RESUMO
We determined the hepatitis E virus (HEV) seroprevalence and detection rate in commercial swine herds in Italy's utmost pig-rich area, and assessed HEV seropositivity risk in humans as a function of occupational exposure to pigs, diet, foreign travel, medical history and hunting activities. During 2011-2014, 2700 sera from 300 swine herds were tested for anti-HEV IgG. HEV RNA was searched in 959 faecal pools from HEV-seropositive herds and in liver/bile/muscle samples from 179 pigs from HEV-positive herds. A cohort study of HEV seropositivity in swine workers (n = 149) was also performed using two comparison groups of people unexposed to swine: omnivores (n = 121) and vegetarians/vegans (n = 115). Herd-level seroprevalence was 75·6% and was highest in farrow-to-feeder herds (81·6%). Twenty-six out of 105 (24·8%) herds had HEV-positive faecal samples (25 HEV-3, one HEV-4). Only one bile sample tested positive. HEV seropositivity was 12·3% in swine workers, 0·9% in omnivores and 3·0% in vegetarians/vegans. Factors significantly associated with HEV seropositivity were occupational exposure to pigs, travel to Africa and increased swine workers' age. We concluded that HEV is widespread in Italian swine herds and HEV-4 circulation is alarming given its pathogenicity, with those occupationally exposed to pigs being at increased risk of HEV seropositivity.

Zoonotic strains of hepatitis E virus (HEV) in Europe have been reported to belong to genotypes 3 and 4. In 2012 and 2013, 57 pig farms in Northern Italy that had previously resulted seropositive for HEV were surveyed for the presence of the virus, with positive samples subsequently genotyped. Hepatitis E RNA was identified in 17/57 (29·8%) seropositive farms. Phylogenetic analysis demonstrated that distinct subtypes of genotype 3 were circulating in the north-east of Italy; as well, for the first time in the Italian swine population, genotype 4 was identified and attributed to subtype d.

Background: Recent trials and reviews have raised question about the safety of total parenteral nutrition (TPN), due to the increased rate of TPN related complications. Diabetic patients are vulnerable to hyperglycaemia, and poor studies have investigated hospital out-comes of diabetic patients requiring TPN. The aim of this study was to evaluate the association of in-hospital mortality, prolonged length of stay and transfer to long-term care facilities among diabetic patients with TPN. Methods: The study considered all hospital admissions of diabetic patients over 65 years of age performed between 2006 and 2015 in Abruzzo Region, Italy. To compare the outcomes of TPN and non-TPN patients, a propensity score matching procedure was performed. Results: A total of 140,556 admissions were analyzed. After matching, 1947 patients were included into the analyses: 649 patients with TPN and 1298 controls. TPN was significantly associated to in-hospital mortality (OR=7.15; 95%CI 5.54-9.22), prolonged LOS (OR=2.78; 95%CI 2.28-3.38) and transfer to LTCF (OR=2.16; 95%CI 1.64-2.85). Discussion: TPN is associated with poor outcomes among elderly diabetic patients in the Italian setting. Being aware of the risk factors among diabetic patients with TPN can be used to anticipate the patients' needs during the admission and the immediate post-discharge period.

Purpose: Globally, age and some comorbidities have been associ-ated with the risk of more severe outcomes of COVID-19. The purpose of this research is to calculate the hospitalization rate of SARS-CoV-2 positive patients in an Italian Local health Authority (LHA) and to examine whether medical comorbidities encoded through pharmaceutical administrative data are predictors of hospital admission in patients with a positive SARS-CoV-2 naso-pharyngeal swab. Methods: This retrospective observational study was conducted in a LHA of Pescara. Comorbidities were coded through the consumption of drugs, using the WHO's Anatomical Therapeutic Chemical (ATC) classification System. The admission was ascertained by checking the hospital discharge records where generated. Results: During the study period, 1571 patients were tested positive for SARS-CoV-2 oro-and-nasopharyngeal swab. Multivariable logistic analisys showed as predictors of admission an age ≥65 in the total sample (aOR 10.91; 95%CI 6.86-17.36) as well as in the male (aOR 12.64;95%CI 6.42-24.87) and female. (aOR 9.27; 95%CI 4.87-17.66) in SARS-CoV-2 positive patients. Comorbidities assiociated with admission were (GERD) in overall (AdjOR 1.58; 95% CI 1.06-2.34) and male (AdjOR 2.30; 95%CI 1.12-4.72) samples and anticoagulants drugs use in male (AdjOR 3.90; 95% 1.11-13.65) sample, the presence of congestive heart failure (CHF) in female (AdjOR 0.47;95%CI 0.27-0.83) sample results as protective factor. Conclusion: In conclusion, increasing age, male gender and PPI use are positively associated while female gender and CHF-related drug use are negatively associated with hospitalization in SARS-CoV-2 positive patients.

Human herpesvirus 8 (HHV8) is pathogenic in humans, especially in cases of immunosuppression. We evaluated the risk of HHV8 transmission from liver donors, and its clinical impact in southern Italy, where its seroprevalence in the general population is reported to be as high as 18.3%. We tested 179 liver transplant recipients and their donors for HHV8 antibodies at the time of transplantation, and implemented in all recipients a 12-month posttransplant surveillance program for HHV8 infection. Of the 179 liver transplant recipients enrolled, 10.6% were HHV8 seropositive before transplantation, whereas the organ donor's seroprevalence was 4.4%. Eight seronegative patients received a liver from a seropositive donor, and four of them developed primary HHV8 infection. Two of these patients had lethal nonmalignant illness with systemic involvement and multiorgan failure. Among the 19 HHV8 seropositive recipients, two had viral reactivation after liver transplantation. In addition, an HHV8 seronegative recipient of a seronegative donor developed primary HHV8 infection and multicentric Castleman's disease. In conclusion, primary HHV8 infection transmitted from a seropositive donor to a seronegative liver transplant recipient can cause a severe nonmalignant illness associated with high mortality. Donor screening for HHV8 should be considered in geographic areas with a high prevalence of such infection.

Mid-infrared (MIR) spectroscopy was used to predict the detailed protein composition of 1,517 milk samples of Simmental cows. Contents of milk protein fractions and genetic variants were quantified by reversed-phase HPLC. The most accurate predictions were those obtained for total protein, casein (CN), α(S1)-CN, ß-lactoglobulin (LG), glycosylated κ-CN, and whey protein content, which exhibited coefficients of determination between predicted and measured values in cross-validation (1-VR) ranging from 0.61 to 0.78. Less favorable were results for ß-CN (1-VR=0.53), α(S2)-CN, and κ-CN (1-VR=0.49). Neither the content of α-LA nor that of γ-CN was accurately predicted by MIR. Predicting the content of the most common milk protein genetic variants (κ-CN A and B; ß-CN A¹, A², and B; and ß-LG A and B) was unfeasible (1-VR <0.15 for the content of κ-CN genetic variants and 1-VR <0.01 for the content of ß-CN variants). The best predictions were obtained for ß-LG A and ß-LG B contents (1-VR of 0.60 and 0.44, respectively). Results indicated that MIR is not applicable for predicting individual milk protein composition with high accuracy. However, MIR spectroscopy predictions may play a role as indicator traits in selective breeding to enhance milk protein composition. The genetic correlation between MIR spectroscopy predictions and measures of milk protein composition needs to be investigated, as it affects the suitability of MIR spectroscopy predictions as indicator traits in selective breeding.

The aim of this study was to investigate the effect exerted by the relative content of κ-casein (κ-CN) B in bulk milk κ-CN on coagulation properties and cheese yield of 3 Italian cheese varieties (Montasio, Asiago, and Caciotta). Twenty-four cheese-making experiments were carried out in 2 industrial and 1 small-scale dairy plant. Detailed protein composition of bulk milk of 380 herds providing milk to these dairies was analyzed by reversed-phase HPLC. To obtain 2 experimental milks differing in the relative content of κ-CN B in κ-CN, herds were selected on the basis of bulk milk protein composition and relative content of κ-CN genetic variants. Milk was collected and processed separately for the 2 groups of selected herds. A difference of 20% in the relative content of κ-CN B in κ-CN was obtained for the 2 experimental milks for Montasio and a difference of 15% for Asiago and Caciotta. The 2 experimental milks were of similar protein and CN content, casein number, pH, CN composition, and ß-CN genetic composition. For each cheese-making trial, amounts of milk, ranging from 2,000 to 6,000kg, were manufactured. Each vat contained milk collected at least from 4 dairy herds. Cheese yield after brining and at the end of the aging was recorded. Milk with a greater proportion of κ-CN B in κ-CN (HIGHB) exhibited similar coagulation properties and greater cheese yield compared with milk with a lower proportion of κ-CN B in κ-CN (LOWB). The increased cheese yield observed for HIGHB when manufacturing Montasio cheese was ascribed to a greater fat content compared with LOWB. The probability of HIGHB giving a cheese yield 5% greater than that of LOWB ranged from 51 to 67% for Montasio cheese, but was less than 21% for Asiago and Caciotta cheeses. Variation in relative content of κ-CN B in κ-CN content did not relevantly affect industrial cheese yield when milks of similar CN composition were processed. An indirect effect due to the increased κ-CN content of κ-CN B milk is thought to explain the favorable effects of κ-CN B on cheese yield reported in the literature.

The aim of this study was to investigate the effects of CSN2-CSN3 (beta-kappa-casein) haplotypes and BLG (beta-lactoglobulin) genotypes on milk production traits, content of protein fractions, and detailed protein composition of individual milk of Simmental cows. Content of the major protein fractions was measured by reversed-phase HPLC in individual milk samples of 2,167 cows. Protein composition was measured as percentage of each casein (CN) fraction to total CN and as percentage of beta-lactoglobulin (beta-LG) to total whey protein. Genotypes at CSN2, CSN3, and BLG were ascertained by reversed-phase HPLC, and CSN2-CSN3 haplotype probabilities were estimated for each cow. Traits were analyzed by using a linear model including the fixed effects of herd-test-day, parity, days in milk, and somatic cell score class, linear regressions on haplotype probabilities, class of BLG genotype, and the random effect of the sire of the cow. Effects of haplotypes and BLG genotypes on yields were weak or trivial. Genotype BB at BLG and haplotypes carrying CSN2 B and CSN3 B were associated with increased CN content and CN number. Haplotypes including CSN3 B were associated with increased kappa-CN content and percentage of kappa-CN to total CN and with decreased percentages of alpha(S1)- and gamma-CN to total CN. Allele CSN2 B had the effect of increasing beta-CN content and decreasing content of alpha(S1)-CN. Haplotypes including allele CSN2 A(1) exhibited decreased beta-, alpha(S2)-, and gamma-CN concentrations and increased alpha(S1)- and kappa-CN contents, whereas CSN2 I had positive effects on beta-CN concentration and trivial effects on content of other protein fractions. Effects of haplotypes on CN composition were similar to those exerted on content of CN fractions. Allele BLG A was associated with increased beta-LG concentration and percentage of beta-LG to total whey protein and with decreased content of other milk proteins, namely beta-CN and alpha(S1)-CN. Estimated additive genetic variance for investigated traits ranged from 14 to 39% of total variance. Increasing the frequency of specific genotypes or haplotypes by selective breeding might be an effective way to change milk protein composition.

The aim of this study was to investigate the effects of CSN2-CSN3 (beta-kappa-casein) haplotypes, BLG (beta-lactoglobulin) genotypes, content of milk protein fractions, and protein composition on coagulation properties of milk (MCP). Rennet coagulation time (RCT) and curd firmness (a(30)) were measured using a computerized renneting meter, and the contents of major milk protein fractions were quantified by reversed-phase HPLC in individual milk samples of 2,167 Simmental cows. Cow genotypes at CSN2, CSN3, and BLG were ascertained by reversed-phase HPLC, and CSN2-CSN3 haplotype probabilities were estimated for each cow. Phenotypes for MCP were regressed on CSN2-CSN3 haplotype probabilities using linear models that also included the effects of herd-test-day, parity, days in milk, pH, somatic cell score, renneting meter sensor, sire of the cow, BLG genotype, and content of major protein fractions or, alternatively, protein composition. When the statistical model did not account for protein fraction contents or protein composition, haplotypes carrying CSN3 B were associated with shorter RCT and greater a(30) compared with those carrying CSN3 A. Haplotypes carrying CSN2 B had the effect of decreasing RCT and increasing a(30) relative to haplotype A(2)A. When effects of protein fractions content or protein composition were added to the model, no difference across haplotypes due to CSN3 and CSN2 alleles was observed for MCP, with the exception of the effect of CSN2 B on RCT, which remained markedly favorable. Hence, the effect of CSN3 B on MCP is related to a variation in protein composition caused by the allele-specific expression of kappa-casein, rather than to a direct role of the protein variant on the coagulation process. In addition, the favorable effect exerted by CSN2 B on a(30) was caused by the increased beta-casein content in milk. Conversely, CSN2 B is likely to exert a direct genetic effect on RCT, which does not depend upon variation of beta-casein content associated with CSN2 B. Increased RCT was observed for milk yielded by BLG BB cows, even when models accounted for protein composition. Rennet clotting time was favorably affected by kappa-casein content and percentage of kappa-casein to total casein, whereas a(30) increased when contents and percentages of beta-CN and kappa-CN increased. Changes of milk protein composition and allele frequency at casein and whey protein genes affect variation of MCP.

PURPOSE: The authors sought to evaluate whether the reacquisition of images 3 h after administration of radiotracer improves the sensitivity of fluorine-18 fluorodeoxyglucose positron emission tomography computed tomography ([(18)F]-FDG PET/CT) in patients with suspicious breast lesions. MATERIALS AND METHODS: Forty-eight patients with 59 breast lesions underwent an [(18)F]-FDG PET/CT study in the prone position with a dual-time-point acquisition performed in the early phase 1 h after FDG administration (PET-1) and in the delayed phase 3 h after FDG administration (PET-2). Both examinations were evaluated qualitatively and semiquantitatively with calculation of the mean percentage variation of the standard uptake values (Delta% SUV(max)) between PET-1 and PET-2. All lesions with an SUV(max) >or=2.5 at PET-1 or a reduction in SUV between PET-1 and PET-2 were considered benign. The definitive histopathological diagnosis was available for all patients included in the study. RESULTS: The dual-time-point acquisition of [(18)F]-FDG PET/CT displayed an accuracy of 85% for lesions with an SUV(max) >or=2.5 and/or positive Delta% SUV(max), with sensitivity and specificity values of 81% and 100% compared with 69%, 63% (both p<0.001) and 100% (p=n.s.), respectively, for the single-time-point acquisition. Malignant lesions showed an increase in FDG uptake between PET-1 and PET-2, with a Delta% SUV(max) of 10+/-7 (p<0.04). In contrast, benign lesions showed a decrease in SUV between PET-1 and PET-2, with a Delta% SUV(max) of -21+/-7 (p<0.001). CONCLUSIONS: The delayed repeat acquisition of PET images improves the accuracy of [(18)F]-FDG PET/CT in patients with suspicious breast lesions with respect to the single-time-point acquisition. In addition, malignant breast lesions displayed an increase in FDG uptake over time, whereas benign lesions showed a reduction. These variations in FDG uptake between PET-1 and PET-2 are a reliable parameter that can be used for differentiating between benign and malignant breast lesions.

AIMS: This study aimed to assess the trend of hospitalizations for DKA in adult patients with type 2 diabetes mellitus and its associated factors. DESIGN: A retrospective cross-sectional study was performed. Data were collected from hospital discharge records (HDRs) of patients (age ≥18) with either primary or secondary discharge diagnosis for DKA and type 2 diabetes from 2006 to 2015 in Abruzzo region. Age-adjusted hospitalization rates were computed by gender and standardized on the regional population in 2006. A logistic regression model was implemented using presence of DKA as dependent variable. RESULTS: We identified 160,366 HDRs with type 2 diabetes. Out of them, 1611 (1.00%) were due to DKA. The hospitalization rates for DKA increased both for male +115.9 and female +142.8%, from 2006 to 2015. The most significant predictors of DKA were age 18-44 (aOR=4.17), uncontrolled diabetes (aOR=1.79), trauma (aOR=1.38), any infection (aOR=1.68), liver disease (aOR=1.29), fluid and electrolyte disorders (aOR=2.09), psychosis (aOR=1.69). CONCLUSIONS: Trends of DKA in adult patients with type 2 diabetes has been increasing in both male and female. Multimorbidity is an open challenge for public health, therefore better coordination is needed among different specialist consultants to reduce the occurrence of this preventable complication.

BACKGROUND: Substance use may influence the onset and course of psychiatric diseases. The "Revolving door" (RD) phenomenon, which indicates repeated hospitalizations of the same patients, has become a public health. OBJECTIVES: The aim of this study was detecting the risk factors associated to hospital readmission to psychiatric wards of drug-addicted patients. METHODS: The study considered all the admissions performed between 2006 and 2015 in Abruzzo, Italy. Only the hospital discharge registry having code 304 (drug dependence) as diagnosis was taken into account. In addition, only the patients with a psychiatric DRG were included. RESULT: 325 patients performed 558 psychiatric admissions during the study period (1089 person-years). The analyses of the discharge registry showed "Psychoses" as the main DRG (73.2%). An amount of 119 patients experienced a second psychiatric admission. Psychiatric readmissions were independently predicted by Schizofrenia (HR=2.061) and Anxiety disorders (HR=0.326). CONCLUSION: Psychiatric hospitalization and readmission are frequent among drug-addicted patients. The subsequent RD phenomenon has become a public health issue, both for health and economic sides.

Noroviruses (NoVs) are one of the major causative agents of non-bacterial gastroenteritis in humans worldwide. NoVs, belonging to Caliciviridae, are classified into ten genogroups (G) and eight P-groups based on major capsid protein (VP1) and of the RNA-dependent-RNA-polymerase (RdRp), respectively. In swine, the main genogroup and P-group identified are GII and GII.P; which can infect humans too. To date, only one case of GIIP.11 have been identified in swine in Italy while the circulation of other P-types is currently unknown. In the present study, 225 swine faecal samples were collected from 74 swine herds in Veneto region through on-farm monitoring. NoV circulation was particularly high in older pigs. The phylogenetic analysis showed the co-circulation of NoVs belonging to two different P-types: GII.P11 and GII.P18, here described for the first time in Italy, presenting an extensive genetic diversity, never described before worldwide. Distinct NoV genetic subgroups and unique amino acid mutations were identified for each P-type for the first time. This study demonstrated the co-circulation of diverse swine NoVs subgroups in Italy, raising questions on the origin of such diversity and suggesting that continuous monitoring of swine NoVs is needed to track the emergence of potentially zoonotic viruses by recombination events.
