RESUMO
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.

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.

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.

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.

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.

RESUMO
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.

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.

There are a few studies that report cognitive impairment as a complication of treatment with beta- blockers. We aimed to evaluate the longitudinal association between use of beta-blockers, as a class, and incident risk of all-cause dementia, vascular dementia, Alzheimer's and mixed dementia in the prospective population-based Malmö Preventive Project. We included 18,063 individuals (mean age 68.2, males 63.4%) followed up for 84,506 person-years. Dementia cases were retrieved from the Swedish National Patient Register and validated by review of medical records and neuroimaging data. We performed propensity score matching analysis, resulting in 3720 matched pairs of beta-blocker users and non-users at baseline, and multivariable Cox proportional-hazards regression. Overall, 122 study participants (1.6%) were diagnosed with dementia during the follow-up. Beta-blocker therapy was independently associated with increased risk of developing vascular dementia, regardless of confounding factors (HR: 1.72, 95%CI 1.01-3.78; p = .048). Conversely, treatment with beta-blockers was not associated with increased risk of all-cause, Alzheimer's and mixed dementia (HR:1.15; 95%CI 0.80-1.66; p = .44; HR:0.85; 95%CI 0.48-1.54; P = .59 and HR:1.35; 95%CI 0.56-3.27; p = .50, respectively). We observed that use of beta-blockers, as a class, is associated with increased longitudinal risk of vascular dementia in the general elderly population, regardless of cardiovascular risk factors, prevalent or incident history of atrial fibrillation, stroke, coronary events and heart failure. Further studies are needed to confirm our findings in the general population and to explore the mechanisms underlying the relationship between use of beta- blockers and increased risk of vascular dementia.

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.

Drinking water for poultry is not subject to particular microbiological, chemical and physical requirements, thereby representing a potential transmission route for pathogenic microorganisms and contaminants and/or becoming unsuitable for water-administered medications. This study assessed the microbiological, chemical and physical drinking water quality of 28 turkey farms in North-Eastern Italy: 14 supplied with tap water (TW) and 14 with well water (WW). Water salinity, hardness, pH, ammonia, sulphate, phosphate, nitrate, chromium, copper and iron levels were also assessed. Moreover, total bacterial count at 22°C, presence and enumeration of Enterococcus spp. and E. coli, presence of Salmonella spp. and Campylobacter spp. were quantified. A water sample was collected in winter and in summer at 3 sampling sites: the water source (A), the beginning (B) and the end (C) of the nipple line (168 samples in total). Chemical and physical quality of both TW and WW sources was mostly within the limits of TW for humans. However, high levels of hardness and iron were evidenced in both sources. In WW vs. TW, sulphate and salinity levels were significantly higher, whilst pH and nitrate levels were significantly lower. At site A, microbiological quality of WW and TW was mostly within the limit of TW for humans. However, both sources had a significantly lower microbiological quality at sites B and C. Salmonella enterica subsp. enterica serotype Kentucky was isolated only twice from WW. Campylobacter spp. were rarely isolated (3.6% of farms); however, Campylobacter spp. farm-level prevalence by real-time PCR was up to 43% for both water sources. Winter posed at higher risk than summer for Campylobacter spp. presence in water, whereas no significant associations were found with water source, site, recirculation system, and turkey age. Low salinity and high hardness were significant risk factors for C. coli and C. jejuni presence, respectively. These results show the need of improving sanitization of drinking water pipelines for commercial turkeys.

During oestrus, fattening female pigs are more prone to lameness, fractures and wounds due to mounting and agonistic behaviours of penmates. This study assessed the effect of sexual maturity on the behaviour and welfare of heavy female pigs slaughtered at 36 weeks of age (180±10 kg) for dry-cured ham production. An immunocastrated control group was used for comparison. In all, 56 15-week-old female pigs, individually identifiable by back tattoos were equally distributed among four pens. All animals from two pens were subject to a three-dose immunocastration schedule at 16, 20 and 32 weeks of age. Skin lesions and behaviours were assessed at 18, 23, 28, 33 and 36 weeks of age. A blood sample was collected at 20, 24, 28 and 32 weeks of age for assessing health/stress parameters and GnRH antibodies. At slaughter, ovaries were weighed, measured and histologically examined; stomachs, carcasses and lungs were scored for lesions and a further blood sample was taken. Immunocastrated pigs did not significantly differ from controls in growth rate, feed efficiency and slaughter performances (lung score, gastric score, backfat thickness). However, they showed a lower frequency of aggressive interactions at 33 and 36 weeks, lower front lesions at 28 weeks, but higher at 30 weeks; a lower haptoglobin level at 28 weeks, a lower level of cortisol and back lesions at slaughter (36 weeks). These findings suggest a low, yet not negligible, impact of sexual maturity on the welfare of heavy female pigs.

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.

The 2017 Faraday Discussion on Surface Enhanced Raman Scattering (SERS) attracted more than a hundred delegates from a broad spectrum of backgrounds and experience levels, bringing together leading scientists involved in the long living field of SERS. The meeting gave an overview of the liveliness of the topic, characterised by open questions and fascinating science still to discover. In the following, we discuss the topics covered during this meeting and briefly highlight the content of each presentation.
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 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
Pre-slaughter transportation may affect poultry welfare and mortality rates. A retrospective analysis was conducted to examine the effect of environmental, management and individual factors on the percentage of dead birds during pre-slaughter transportation (dead-on-arrival, DOA). The variables accounted for in the analyses included: environmental temperature, travel duration, genetic line, gender, crate type and crate stocking density. Among the 41 452 loads of turkeys (34 696 388 birds) and 3241 of end of lay hens (21 788 124 birds) transported to three large abattoirs in northern Italy in a 3-year period, the median DOA was 0.14% in turkeys, and 0.38% in hens. In turkeys, travel duration longer than 30 min, temperature higher than 26°C and high in-crate densities were associated with increased DOA. In winter (⩽2°C), high stocking densities did not reduce the mortality risk from cold stress; on the contrary, for stocking densities either near to or just above the maximum density in EC Reg. 1/2005, the DOA risk was greater than for loads with densities of 10 kg/m2 less than the EC maximum. Male birds and specific genetic lines also showed a higher DOA. In hens, transportation lasting longer than 2 h and the brown-feathered breed were associated with higher DOA. Dead-on-arrival progressively increased with travel duration, remaining constant between 4 and 6 h and peaking at 8 h (median: 0.57%). The maximum DOA increase was detected during winter. These results show that several species-specific factors may lead to increased risk of mortality.

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.

OBJECTIVE: Vulvar intraepithelial neoplasia (VIN) is a premalignant lesion of the vulva. The incidence of VIN is increasing. The surgery is currently the gold standard therapy for VIN, but Imiquimod could be a completion to surgery. The aim of this study is to compare the overall complete response, the recurrence rate and the risk factors for recurrence among two groups of patients: women with high grade VIN underwent surgery and patients treated with surgery plus Imiquimod. PATIENTS AND METHODS: 80 patients with histologically diagnosed VIN 2/3 were enrolled in this prospective study. Our patients were divided into two groups: 40 women underwent surgery (A) and 40 patients were treated with surgery plus Imiquimod (B). All women had a 5-year follow-up. Recurrence rate and complete response were evaluated. The following patients' characteristics were analyzed: smoke, multifocal disease, multicentric disease, degree of the lesion. RESULTS: In the group A recurrence rate was 44.8%, in the group B it was 48.4%. In both groups the presence of multifocal lesions (p = 0.02) and VIN 3 (p = 0.006) before treatment was associated with a higher risk of recurrence. CONCLUSIONS: This study found that surgery remains the principal approach for VIN with regard to relapse and complete response since the treatment with Imiquimod associated with surgery didn't show a lower recurrence rate. Although the surgical treatments remain the best therapeutic option for VIN with regard to recurrence and overall complete response, the combined therapy seems to be an interesting modality, but further studies are needed.
