Institution of an interdisciplinary IBD centre is associated with improved healthcare utilisation.

Despite the institution of an interdisciplinary Inflammatory Bowel Disease (IBD) centre is encouraged, how it may improve patient care is still unknown. In a 5-year period following organisation of an IBD centre, hospitalisations per patient/year decreased (0.41-0.17) and patients on biologics increased (7.7%-26.7%). Total number of hospitalisations (-18.4%) and length of hospitalisation (-29.4%) improved compared with a preceding 5-year period. These findings suggest that institution of an interdisciplinary IBD centre is associated with improved healthcare utilisation.

Prevalence of genital HPV infection in STI and healthy populations and risk factors for viral persistence.

Human papillomavirus (HPV) is a well-established carcinogenic agent. This study aimed to assess prevalence and persistence rate of genital HPV infection in sexually transmitted infections (STIs) patients and healthy subjects. The risk factors influencing the persistence of genital HPV infection were also investigated. The samples were collected with the ThinPrep liquid-based cytology system. Among the HPV-positive patients, those consenting were retested after 12 months. Overall, 145/292 subjects proved HPV positive with a higher prevalence (51%) in STI than in healthy population (43%). The persistence of genital HPV infection was statistically associated with female gender, HR-HPV infection, smoking, and Ureaplasma parvum infection.

Analysis of incidents of violence in a large Italian hospital. / Analisi degli episodi di violenza in in grande ospedale italiano.

INTRODUCTION: An increase in the rate of non-fatal violence events, from 20.65/10,000 in 2012 to 22.81/10,000 in 2014, was observed at the IRCCS Ospedale Policlinico San Martino in Genoa. OBJECTIVES: To analyze the incidence and outcome of the phenomenon of violence, by identifying the type of aggressive event and the ward in which it occurred, assuming that the occurrence is evenly distributed and not only limited to the psychiatric or to the emergency department. The age and sex of both attackers and victims of aggression were also analyzed. METHODS: Retrospective analysis: study of injury trends related to episodes of violence between 2012 and 2015, incidence compared to other injuries and evaluation of the direct costs. Observational staff surveys with a questionnaire based on the Overt Aggression Scale and statistical data analysis. RESULTS: Following the aggressions, 36 injuries were identified over the study period (2012-2015), resulting in 431 days of absence from work. The direct estimated costs were € 64,170. The observational surveys of each ward showed a high concentration of events. Reports were received from 34 out of the 76 evaluated wards. Seventy-five percent of the reports concerned only four operative units: emergency room, intermediate care, psychiatry and geriatrics. Sixty-one percent of the questionnaires were filled out by nurses, 23% by support staff and the remaining 16% was provided by physicians and coordinators. CONCLUSIONS: Violence against healthcare workers is a well-known problem; action is required on the scheduling of activities, improvement of communication paths with users and the training of operators.

Trends in the annual incidence of carbapenem-resistant Klebsiella pneumoniae bloodstream infections: a 8-year retrospective study in a large teaching hospital in northern Italy.

BACKGROUND: Bloodstream infections (BSI) due to carbapenem-resistant (C-R) Klebsiella pneumoniae (Kp) are of global concern from both clinical and public health standpoints. This retrospective study aimed to describe C-R Kp BSI epidemiology in a large teaching hospital in northern Italy. METHODS: Between 1 January 2007 and 31 December 2014, annual incidences both of C-R Kp BSI and of carbapenem-susceptible (C-S) Kp BSI were calculated as the number of events per 10,000 patient-days. A Chi square test for linear trend was used to assess the change in the incidence of C-R Kp BSI and C-S Kp BSI over the study period. Crude 30-day mortality rates were provided both for C-R Kp BSI and for C-S Kp BSI. RESULTS: From 2007 to 2014, we observed 511 episodes of Kp BSI, 349 of which were caused by C-R Kp (68.3 %). The incidence of C-R Kp BSI considerably increased from 0.04/10,000 patient-days in 2007 to 1.77/10,000 patient-days in 2014 (Chi square for trend p < 0.001). The highest incidence of C-R Kp BSI was observed in intensive care units (ICUs), with a peak of 22.01 C-R Kp BSI/10,000 patient-days in 2012. A less marked but significant increase of C-S Kp BSI was also observed (Chi square for trend p = 0.004). Crude 30-day mortality was 36.1 % in patients with C-R Kp BSI and 23.5 % in those with C-S Kp BSI. CONCLUSIONS: During the study period, we observed a dramatic increase in the incidence of C-R Kp BSI in our hospital. More concerted infection-control efforts are needed to contain this alarming C-R Kp diffusion.

Latent tuberculosis infection and associated risk factors among undergraduate healthcare students in Italy: a cross-sectional study.

BACKGROUND: The screening of both healthcare workers and students attending teaching hospitals for latent tuberculosis infection (LTBI) is recommended in hospitals of many countries with a low-incidence of TB, including Italy, as a fundamental tool of tuberculosis (TB) control programs. The aim of the study was to estimate the prevalence of LTBI and evaluate the main risk-factors associated with this condition in a cohort of healthcare Italian students. METHODS: In a cross-sectional study, performed between January and May 2012, 881 undergraduate students attending the Medical, Nursing, Pediatric Nursing and Midwifery Schools of the University of Genoa, trained at the IRCCS San Martino-IST Teaching Hospital of Genoa, were actively called to undergo the Tuberculin Skin Test (TST). All the TST positive cases were also tested with an Interferon-Gamma Release Assay (IGRA) to confirm the diagnosis of LTBI. A standardized questionnaire was collected for risk-assessment analysis. RESULTS: Seven hundred and thirty-three (83.2%) subjects underwent TST testing. The prevalence of TST positives was 1.4%, and in 4 (0.5%) out of 10 TST positive cases LTBI diagnosis was confirmed by IGRA. No difference in the prevalence of subjects who tested positive to TST emerged between pre-clinical (n = 138) and clinical (n = 595) students. No statistically significant association between TST positivity and age, gender, and BCG vaccination was observed. The main independent variable associated with TST positivity was to be born in a country with a high TB incidence (i.e., ≥20 cases per 100,000 population) (adjusted OR 102.80, 95% CI 18.09-584.04, p < 0.001). CONCLUSIONS: The prevalence of LTBI among healthcare students resulted very low. The only significant association between TST positivity and potential risk factors was to be born in high TB incidence areas. In countries with a low incidence of TB, the screening programs of healthcare students before clinical training can be useful for the early identification and treatment of the sporadic cases of LTBI.

Immunonutrition in major oncologic head and neck surgery: Analysis of complications, plasmatic equilibrium, and costs.

BACKGROUND: Malnutrition, in patients with solid tumors, is associated with a worse clinical outcome and about 40% of patients affected by head and neck cancers (HNC) are malnourished at the time of cancer diagnosis. We investigated the potential benefit of a standardized immunonutritional protocol (INP) to patients with HNC receiving major ablative surgery. METHODS: An observational study was conducted enrolling 199 patients: 50 treated with the INP and 149 with standard enteral nutrition. Complication rates, need for medications, and costs were considered as outcomes. RESULTS: INP played a protective role in development of major surgical complications (OR 0.23, p = 0.023), albumin administration (RR 0.38, p = 0.018), and antibiotic duration (p < 0.001) and is cost-effective in patients with moderate or severe malnutrition (-6083€ and -11 988€, p < 0.05). CONCLUSIONS: Our study supports the utility of INP, and accurate nutritional screening can help to identify malnourished patients who would receive the most benefits from this protocol.

Cervical, oral and anal Human papillomavirus infection in women attending the Dermatology Unit of a regional reference hospital in Genoa, Italy: a prevalence study.

Human papillomavirus (HPV) infection is the most common sexually transmitted infection (STI) worldwide. In women with genital infection, the virus can be transmitted by sex to the oral cavity of their partners and then to their own oral cavity. The aim of the present study was to establish the prevalence of cervical/anal/oral HPV infection in women attending the Dermatology Unit of the Policlinico San Martino of Genoa, the regional reference hospital in Liguria, Italy. Methods: Between January 2016 and December 2018, the female patients attending the STI center (cases) and those requiring a full body skin examination for skin cancer screening ("supposed" healthy population: controls) were recruited. Cervical/anal/oral samples were collected with ThinPrep liquid based cytology preparation system: polymerase chain reaction for HPV and cytological evaluation were performed. Overall, 85 cases and 31 controls were recruited. Results: Cervical HPV infection was detected in 60% of the cases and 48% of the controls; anal HPV infection in 44% of the cases and 26% of the controls. Cervical and anal HPV infection resulted associated, especially in the control group. Moreover, 32% of the cases and 29% of the controls proved HPV positive in the oral cavity. In the cases of our series, prevalence of cervical, anal and oral HPV infection was higher compared with the controls. Conclusions: The high prevalence of anal-oral infections and the frequent association between anal and cervical infections, provide reason to suggest HPV screening also in the anal and oral regions, which may represent HPV reservoirs and grounds for cancer development.

Study on the impact of sexually transmitted infections on Quality of Life, mood and sexual function.

BACKGROUND: Sexually transmitted infections (STIs) may impact on the patient's physical, psychological and sexual health and negatively influence their Quality of Life (QOL). Studies on this topic are scarce. This study aimed to assess the impact of STIs different from HIV on QOL, mood and sexual functioning in the patients attending our STIs center in comparison with patients affected by chronic inflammatory bowel diseases (IBD). METHODS: An anonymous questionnaire was provided. It included 3 validated questionnaires: the European Quality of Life 5 dimensions 5 levels; the Beck Depression Inventory-II for depressive symptoms; the Changes in Sexual Functioning Questionnaire (CSFQ) for sexual functioning. RESULTS: Seventy-three STIs patients and 51 IBD patients participated in the study. The mean EQ-5D-5L questionnaire scores were 86.72 in STIs and 89.21 in IBD patients, without statistically significant difference between the two groups. Symptoms of depression were more common and severe in STIs patients compared to IBD patients. Sexual functioning was slightly worse in STIs patients than in IBD patients. CONCLUSIONS: This is one the very few studies focused on the impact of STIs on patient's physical, psychological and sexual health. Physicians dealing with STIs should consider the possible psychological consequences of the disease.

Hopelessness and Post-Traumatic Stress Symptoms among Healthcare Workers during the COVID-19 Pandemic: Any Role for Mediating Variables?

The Coronavirus-19 (COVID-19) pandemic has many psychological consequences for the population, ranging from anxious-depressive symptoms and insomnia to complex post-traumatic syndromes. This study aimed to evaluate the impact of the Covid-19 pandemic on the mental well-being of healthcare workers, focusing on the association between hopelessness, death anxiety, and post-traumatic symptomatology. Eight hundred forty-two healthcare workers were recruited between 21 March 2020 and 15 May 2020. A specific questionnaire was administered to assess socio-demographic and clinical characteristics, together with psychometric scales: Beck Hopelessness Scale, Death Anxiety Scale (DAS), and Davidson Trauma Scale (DTS). Respondents with hopelessness scored higher in the DAS and DTS than respondents without hopelessness. Furthermore, death anxiety was identified as a potential mediator of the significant association between hopelessness and post-traumatic symptomatology. The impact of death anxiety should be recognized in vulnerable populations, such as frontline healthcare workers. Therefore, pharmacological and non-pharmacological strategies could be useful to attenuate the negative psychological consequences and reduce the burden worldwide.

Changes in sex steroid levels in women with epilepsy on treatment: relationship with antiepileptic therapies and seizure frequency.

PURPOSE: Reproductive dysfunction in epilepsy is attributed to the seizures themselves and also to antiepileptic drugs (AEDs), which affect steroid production, binding, and metabolism. In turn, neuroactive steroids may influence neuronal excitability. A previous study in this cohort of consecutive women with epilepsy showed that patients with more frequent seizures had higher cortisol and lower dehydroepiandrosterone sulfate levels than those with rare or absent seizures. The present study was aimed at evaluating, in these same women, the possible relationship between some clinical parameters, seizure frequency, AED therapies, and sex hormone levels. METHODS: Estradiol (E2), progesterone (Pg), sex hormone-binding globulin (SHBG), and free estrogen index (FEI) were measured during the luteal phase in 113 consecutive females, 16-47 years old, with different epilepsy syndromes on enzyme-inducing AED (EIAED) and/or non-enzyme-inducing AED (NEIAED) treatments, and in 30 age-matched healthy women. Hormonal data were correlated with clinical parameters (age, epilepsy syndrome, disease onset, and duration), seizure frequency assessed on the basis of a seizure frequency score (SFS), and AED therapies. RESULTS: E2, Pg, and FEI were lower, whereas SHBG levels were higher in the epilepsy patients than in the controls. However, sex steroid and SHBG levels were not different between groups of patients categorized according to SFS. Therapies with EIAEDs accounted for changes in E2 levels and FEI. CONCLUSIONS: Despite globally decreased sex steroid levels in serum, actual hormone titers were not significantly correlated with SFS in consecutive epilepsy women; rather, these hormonal changes were explained by AED treatments, mainly when EIAED polytherapies were given.

Economics of One Health: Costs and benefits of integrated West Nile virus surveillance in Emilia-Romagna.

Since 2013 in Emilia-Romagna, Italy, surveillance information generated in the public health and in the animal health sectors has been shared and used to guide public health interventions to mitigate the risk of West Nile virus (WNV) transmission via blood transfusion. The objective of the current study was to identify and estimate the costs and benefits associated with this One Health surveillance approach, and to compare it to an approach that does not integrate animal health information in blood donations safety policy (uni-sectoral scenario). Costs of human, animal, and entomological surveillance, sharing of information, and triggered interventions were estimated. Benefits were quantified as the averted costs of potential human cases of WNV neuroinvasive disease associated to infected blood transfusion. In the 2009-2015 period, the One Health approach was estimated to represent a cost saving of €160,921 compared to the uni-sectoral scenario. Blood donation screening was the main cost for both scenarios. The One Health approach further allowed savings of €1.21 million in terms of avoided tests on blood units. Benefits of the One Health approach due to short-term costs of hospitalization and compensation for transfusion-associated disease potentially avoided, were estimated to range from €0 to €2.98 million according to the probability of developing WNV neuroinvasive disease after receiving an infected blood transfusion.

Resting SPECT-neuropsychology correlation in very mild Alzheimer's disease.

OBJECTIVE: To investigate the relationships between brain function and some of the most frequently impaired cognitive domains in the first stages of Alzheimer's disease (AD), we searched for correlation between the scores on 3 neuropsychological tests and brain perfusion, assessed by single photon emission computed tomography (SPECT) in patients with very mild AD. METHODS: Twenty-nine consecutive outpatients (mean age 78.2+/-5.5) affected by probable AD in the very mild phase (i.e. with a score > or =20 on the mini-mental state examination, MMSE) underwent brain SPECT with (99m)Tc-ethylcisteinate dimer. For correlative purposes, word list learning (by the selective reminding test, SRT), constructional praxis test (CPT) and visual search test (VST) were chosen a priori out of an extended battery employed to diagnose AD at first patient evaluation. Voxel-based correlation analysis was achieved by statistical parametric mapping (SPM99) with a height threshold of P=0.005. Age, years of education and the MMSE score were inserted in the correlative analysis as confounding variables. RESULTS: The SRT score showed correlation with brain perfusion in 3 clusters of the left hemisphere, including the post-central gyrus, the parietal precuneus, the inferior parietal lobule and the middle temporal gyrus, and in one cluster in the right hemisphere including the middle temporal gyrus and the middle occipital gyrus. The CPT score was significantly correlated with brain perfusion in the parietal precuneus and the posterior cingulate gyrus in the left hemisphere, whereas the VST score gave a significant correlation with brain perfusion in a left cluster including the parietal precuneus and the superior temporal gyrus. CONCLUSIONS: Cognitive impairment in very mild AD is reflected by brain dysfunction in posterior associative areas, with peculiar topographical differences proper of each domain. The parietal precuneus was a common site of correlation of all 3 neuropsychological tests. This region, together with the posterior cingulate and the superficial posterior temporal-parietal cortex, is thought to be affected by disconnection from the mesial temporal lobe, besides being directly affected by increased oxidative stress and by atrophy as well. The impairment of these areas is thought to contribute to cognitive decline in verbal memory, constructional praxis and visual sustained attention which are indeed among the earliest signs of cognitive impairment in AD. SIGNIFICANCE: Assessing the relationships between neuropsychology and brain functional imaging is a key approach to clarify the pathophysiology of cognitive failure in AD; the specificity of these findings in AD remains to be proven through comparison with correlation achieved in matched controls.

Latent tuberculosis infection among a large cohort of medical students at a teaching hospital in Italy.

The surveillance of latent tuberculosis infection (LTBI) in both healthcare workers and healthcare students is considered fundamental for tuberculosis (TB) prevention. The aim of the present study was to estimate LTBI prevalence and evaluate potential risk-factors associated with this condition in a large cohort of medical students in Italy. In a cross-sectional study, performed between March and December 2012, 1511 eligible subjects attending the Medical School of the University of Genoa, trained at the IRCCS San Martino-IST Teaching Hospital of Genoa, were actively called to undergo the tuberculin skin test (TST). All the TST positive cases were confirmed with an interferon-gamma release assay (IGRA). A standardized questionnaire was collected for multivariate risk analysis. A total of 1302 (86.2%) students underwent TST testing and completed the questionnaire. Eleven subjects (0.8%) resulted TST positive and LTBI diagnosis was confirmed in 2 (0.1%) cases. Professional exposure to active TB patients (OR 21.7, 95% CI 2.9-160.2; P value 0.003) and previous BCG immunization (OR 28.3, 95% CI 3.0-265.1; P value 0.003) are independently associated with TST positivity. Despite the low prevalence of LTBI among Italian medical students, an occupational risk of TB infection still exists in countries with low circulation of Mycobacterium tuberculosis.

Severity of bone marrow involvement in patients with Gaucher's disease evaluated by scintigraphy with 99mTc-sestamibi.

UNLABELLED: Gaucher's disease is a lysosomal storage disorder due to a genetically transmitted deficiency of the enzyme glucocerebrosidase. In the most common form of the disease (type 1), accumulation of glucosylceramide in the reticuloendothelial cells of liver, spleen, and bone marrow leads to visceromegaly, anemia, thrombocytopenia, and osteopenia. Skeletal manifestations secondary to infiltration of the bone marrow by Gaucher's cells are detectable by radiography only in advanced stages. Imaging of bone marrow involvement can be performed indirectly by magnetic resonance techniques or by bone marrow scintigraphy with radiocolloids. However, both procedures lack specificity because the normal bone marrow, rather than the pathologic process, is imaged. The aim of this study was to assess the reliability of (99m)Tc-sestamibi scintigraphy for direct evaluation of bone marrow involvement. METHODS: Seventy-two patients with type 1 and 2 patients with type 3 Gaucher's disease (35 males, 39 females) were enrolled in the study. The mean age +/- SD was 31.9 +/- 16.5 y (range, 3-76 y), and the average duration of the disease manifestations when performing scintigraphy was 12.95 y (median, 10.5 y; range, 0-44 y). Forty-three of 74 patients had never received enzyme replacement therapy (ERT), whereas 31 patients were already being treated with ERT. (99m)Tc-Sestamibi was injected intravenously (6-8 MBq/kg of body weight) and imaging was recorded at the lower limbs 30 min after injection, at the plateau of tracer accumulation in the involved bone marrow. The scans were evaluated visually, assigning a semiquantitative score based on the extension and intensity of uptake in the bone marrow of the lower limbs (0 = no uptake; 8 = maximum uptake). The scintigraphic score was entered into complex statistical analysis, which included a series of clinical and blood chemistry parameters defining overall severity of the disease. RESULTS: (99m)Tc-Sestamibi scintigraphy showed that 71 of 74 patients had some degree of bone marrow involvement. The scintigraphic score was highly correlated with an overall clinical severity score index (SSI) and with various parameters contributing to the SSI, either positively or negatively. The highest correlation of the scintigraphic score was found with an overall biochemical marker of disease severity (serum chitotriosidase). ERT-naive patients showed high correlation of the scintigraphic score with the clinical SSI, with a radiographically based score, and with serum chitotriosidase. In the ERT-treated patients, the scintigraphic score was correlated with the clinical SSI, with hepatomegaly, and with hemoglobin. CONCLUSION: (99m)Tc-Sestamibi uptake reliably identifies bone marrow infiltration by Gaucher's cells. The scintigraphic score is helpful for defining the severity of bone marrow involvement and for comparing patients. (99m)Tc-Sestamibi scintigraphy, which provides topographic information about the sites involved by the disease, is highly correlated with other parameters of disease severity and appears to correlate with response to ERT.

Animal age-, dose- and cell line-dependent growth of human neuroblastoma in nude mice. A statistical analysis.

Cells lines from human neuroblastoma (NB) and T/lymphoma (T-L) were injected subcutaneously (sc) in female CD1 nu/nu athymic nude mice. Results obtained after the observation of tumour growth were statistically analyzed by SAS. The following four parameters were considered: 1) dose of injected cells, 2) type of injected tumour (NB or T-L), 3) age of mice after individuation of three groups of animals (group A, 4-9 weeks old, group B, 9-20 weeks old, group C, > 20 weeks old), 4) injected cell line within the same tumour type. Latency time (LT), corresponding to the interval between cell inoculum and the appearance of a 5 mm diameter subcutaneous mass, and survival time (ST), corresponding to the interval between cell inoculum and the appearance of a 20 mm diameter subcutaneous tumour mass, were considered to evaluate tumour growth. Results showed that mass progression is affected by the number of injected cells and both LT and ST are age- and dose-dependent; furthermore, significant differences were recorded by using different NB and T-L cell lines. Group C showed longer LT than other groups; group B animals showed a statistically significant longer ST than groups A and C (p < 0.001). Our results indicate that growth of human NB in athymic mice is faster in young animals, which also show a significantly poorer prognosis, while better ST was observed in old and middle-aged animals. Results show statistically significant differences of both LT and ST in animals differing in age and in animals inoculated with different cell amounts. These results seem not to be related with biological properties of NB cells too, since neither the occurrence of MYCN amplification nor chromosome 1p deletion significantly modified such behaviour.

Seizure frequency and cortisol and dehydroepiandrosterone sulfate (DHEAS) levels in women with epilepsy receiving antiepileptic drug treatment.

PURPOSE: Hormonal changes occur in epilepsy because of seizures themselves and of antiepileptic drug (AED) effects on steroid production, binding, and metabolism. Conversely, steroids may influence neuron activity and excitability by acting as neuroactive steroids. This cross-sectional observational study aimed to evaluating cortisol and dehydroepiandrosterone sulfate (DHEAS) levels in female epilepsy patients with different disease severity, as assessed by a seizure frequency score (SFS). METHODS: Morning serum levels of cortisol and DHEAS were assayed in 113 consecutive women, aged 16 to 47 years, with varied epilepsy syndromes, receiving mono- or polytherapy with enzyme-inducing and/or noninducing antiepileptic drugs (AEDs). Hormonal data were correlated with clinical parameters (age, body mass index, epilepsy syndrome, disease onset and duration, SFS, AED therapy, and AED serum levels) and compared with those of 30 age-matched healthy women. RESULTS: In epilepsy patients, cortisol levels and cortisol-to-DHEAS ratios (C/Dr) were significantly higher, whereas DHEAS levels were significantly lower than those in controls. Patients with more frequent seizures showed higher cortisol and C/Dr values and lower DHEAS levels than did those with rarer or absent seizures during the previous 6 months. SFS mainly explained the increase of cortisol levels and C/Dr in patients with more active disease. Changes in DHEAS levels correlated with SFS and epilepsy syndrome, as well as with AED treatments and ages. CONCLUSIONS: Women with more frequent seizures had alterations of their adrenal steroids characterized by an increase of cortisol and a decrease of DHEAS levels. Such hormonal changes might be relevant in seizure control and in patient health.
