RESUMO
PURPOSE: The aim of the present study is to evaluate the association of metabolic and glycemic variables with semen parameters in patients with type 1 diabetes (T1D) with and without erectile dysfunction (ED). METHODS: The study population included 88 adults with T1D using a continuous glucose monitoring, of whom 28 with ED (ED group) and 60 without it (NO ED group). All men completed the International Index of Erectile Function (IIEF-5) and underwent body composition analysis (BIA) and semen analysis. RESULTS: ED group showed worse HbA1c levels [median (IQR), 8.4 (7.7, 9.9) vs 7.4 (7, 8.2) %, P < 0.001)], higher insulin dose [60 (51, 65) vs 45 (38, 56) UI/die, P = 0.004)] and a higher total body water and intracellular water as compared with ED group. Men in the ED group presented higher semen volume [2.8 (2.6, 4.2) vs 2.5 (2.2, 2.7) mL, P < 0.001] and sperm concentration [24 (19, 29) vs 20 (12, 23) mil/mL, P = 0.010], but reduced sperm progressive motility [28 (25, 35) vs 35 (25, 36) %, P = 0.011], higher rate of non-progressive motility [15 (10, 15) vs 10 (5, 10) %, P < 0.001] and higher rate of typical morphology [7(5, 8) vs 5 (4, 5) %, P = 0.001]. Based on multivariate logistic regression analysis performed to assess the association between clinical variables and ED, intracellular water (OR 3.829, 95% CI 1.205, 12.163, P = 0.023) resulted as the only independent predictor of ED. CONCLUSION: Men with T1D and ED showed worse metabolic profile which is associated with poor semen quality, as compared with those without ED.

BACKGROUND: Numerous reports of resistance to terbinafine in Trichophyton spp. from all over the world are arousing justified attention and concern. Point mutations in the gene that encodes the squalene epoxidase (SQLE) enzyme are responsible for these therapeutic resistances. OBJECTIVES: Primary objective of the study was to describe first isolates of Trichophyton spp. resistant to terbinafine among the patients treated between September 2019 and June 2022 at the Dermatology Units of Ospedale Maggiore Policlinico and San Bortolo Hospital. Secondary objective was to study the resistance mechanism. METHODS: Patients with confirmed Trichophyton spp. infection has been treated with systemic and topical terbinafine. Patients were then re-evaluated 12 weeks after the therapy. Patients with incomplete or absent response to terbinafine underwent a new skin scraping for direct mycological examination, new identification of dermatophyte species from culture and MALDI-TOF, molecular species identification, antifungal susceptibility testing and molecular analysis of SQLE gene. RESULTS: We identified five patients without clinical response to treatment with terbinafine. The DNA sequencing of the ITS region identified one Trichophyton rubrum and four Trichophyton indotineae. The T. rubrum strain showed minimum inhibitory concentration (MIC) (90% growth inhibition) of 4 mg/L for terbinafine. The four T. indotineae strains showed a MICs range of 0.25-4 mg/L for terbinafine. The analysis of the SQLE gene in the T. rubrum strain showed a nucleotide substitution generating a missense mutation (L393F). The SQLE gene sequencing in the T. indotineae strains showed a nucleotide substitution generating a missense mutation (F397L) in two strains, a nucleotide substitution L393S in one strain and a nucleotide substitution F415C in another strain. CONCLUSIONS: We report the first cases of terbinafine-resistant Trichophyton isolates in the Italian population. Solid antifungal management programs will be needed to promote more responsible use of antimycotics and preserve their therapeutic efficacy to control antifungal resistance.

BACKGROUND: Probiotic oral intake, via modulation of the microbiota-gut-brain axis, can impact brain activity, mood, and behavior; therefore, it may be beneficial against psychological distress and anxiety disorders. Inflammatory cytokines can influence the onset and progression of several neurodegenerative mood disorders, and the IL-1ß rs16944 SNP is related to high cytokine levels and potentially affects mood disorders. The aim of this study was to examine the combined effect of IL-1ß polymorphism and probiotic administration in mood disorder phenotypes in the Italian population. METHODS: 150 subjects were randomized into two different groups, probiotic oral suspension group (POSG) and placebo control group (PCG), and received the relative treatment for 12 weeks. Psychological profile assessment by Hamilton Anxiety Rating Scale (HAM-A), Body Uneasiness Test (BUT), and Symptom Checklist 90-Revised (SCL90R) was administered to all volunteers. Genotyping was performed on DNA extracted from salivary samples. RESULTS: After 12 weeks of intervention, a significant reduction of HAM-A total score was detected in the POSG (p < 0.01), compared to the PCG. Furthermore, IL-1ß carriers have moderate risk to develop anxiety (OR = 5.90), and in POSG IL-1ß carriers, we observed a reduction of HAM-A score (p = 0.02). CONCLUSIONS: Consumption of probiotics mitigates anxiety symptoms, especially in healthy adults with the minor A allele of rs16944 as a risk factor. Our results encourage the use of probiotics in anxiety disorders and suggest genetic association studies for psychobiotic-personalized therapy.

BACKGROUND: Healthcare professionals might play a significant role in tobacco control. The aims of this study were to investigate tobacco cigarette and electronic cigarette (e-cigarette) consumption among university students enrolled in courses of the healthcare area, and to understand whether training in healthcare could induce to smoking cessation. STUDY DESIGN: Cross-sectional survey using a self-administered, structured questionnaire. METHODS: Tobacco smoking habits of 560 students of four different medical area courses at the University of Milan, enrolled both in the first and in the last course year during the 2017-2018 academic year, were collected. RESULTS: The prevalence of smokers was 34.8%, almost the same for males and females, and higher in Italian students compared to foreigners. Smoking prevalence was higher among employed (46.9%) than unemployed (35.1%) students, without differences between healthcare and non-healthcare workers. The influence of family, and particularly friends, is confirmed to be relevant. About 25% of respondents tried e-cigarettes, mainly smokers (44.6%) and former smokers (38.6%) with the goal of quitting smoking. More than 44% were dual users of both tobacco cigarettes and e-cigarettes. Comparing smoking habits between first-year and final-year students, only students of healthcare assistance course showed a significant drop in smoking during the university studies. CONCLUSIONS: The implementation of specific educational curricula on smoking dangers and on smoking cessation techniques might have the double effect of supporting students in quitting smoking and of properly preparing them for their future task of helping people to quit smoking.

OBJECTIVES: The aim of this study was to demonstrate in a prospective multicentre study that Barbed Reposition Pharyngoplasty (BRP) procedure is safe and effective in management of obstructive sleep apnoea/hypopnea syndrome (OSAHS) patients. DESIGN: Prospective study. SETTING: Multicentre study. PARTICIPANTS: Patients suffering from obstructive sleep apnoea. MAIN OUTCOMES MEASURES: Values of postoperative apnoea-hypopnea index (AHI), oxygen desaturation index (ODI), epworth sleepiness scale (ESS). RESULTS: 111 Barbed Reposition Pharyngoplasty procedures standing alone or as a part of multilevel surgery for OSAHS, performed between January and September 2016, were analysed in 15 different centres. The average hospitalisation period was 2.5 ± 0.5 days. The mean patient age was 46.3 ± 10.5 years. The average body mass index at the time of the procedure was 27.9 ± 3.2, and the majority of the patients were men (83%). The mean preoperative and postoperative apnoea/hypopnea index was 33.4 ± 19.5 and 13.5 ± 10.3, respectively (P < .001). The mean preoperative and postoperative ESS score was 10.2 ± 4.5 and 6.1 ± 3.6, respectively (P < .001). The mean preoperative and postoperative ODI were 29.6 ± 20.7 and 12.7 ± 10.8, respectively (P < .001). CONCLUSIONS: Patients undergoing BRP standing alone or as part of a multilevel approach for the treatment of OSAHS have a reasonable expectation for success with minimal morbidity.

The epidemiological scenarios of hepatitis E virus (HEV) and hepatitis A virus (HAV) infections have changed in the last few decades, but precise epidemiological data on the prevalence of anti-HEV and anti-HAV, alone or in combination, in the general population are scanty. We investigated HEV and HAV seroprevalence comparing two population samples living in Northern (Abbiategrasso, Milan) and Southern Italy (Cittanova, Reggio Calabria), the latter being characterized by a poorer socio-economic level and hygienic/sanitary conditions. Based on census records, we randomly enrolled and tested 3,365 subjects (Abbiategrasso, n = 2,489; Cittanova, n = 876) aged 18-75 years for anti-HAV and anti-HEV. Anti-HAV (71.3 % vs 52.5 %) and anti-HEV (17.8 % vs 9.0 %) prevalence rates were higher in Southern Italy (both p < 0.001). Most anti-HEV-positive subjects also had anti-HAV. Subjects testing positive for anti-HAV, alone or with anti-HEV, were older (p < 0.001 in both populations) and showed a trend toward declining prevalence in the youngest birth cohorts. The prevalence of subjects with a positive result for anti-HEV alone did not change in birth cohorts in the two towns. Detection of anti-HEV was independently associated with anti-HAV, town, birth cohort, and education level in multivariate analysis. Low socio-economic level and hygienic/sanitary conditions are associated with high HAV and HEV seroprevalence rates in Italy. Recent improvements, especially in the South, have led to a declining prevalence of anti-HAV, alone or with anti-HEV. Seroprevalence of HEV alone is uniformly low and does not change in birth cohorts born between 1938 and 1993.

INTRODUCTION: Early-onset dementia (EOD) is defined as dementia with onset before the age of 65 years. EOD is increasingly recognised as an important clinical and social problem with devastating consequences for patients and caregivers. OBJECTIVE: Determine the annual crude incidence rate and the specific incidence rates by sex and age in patients with EOD, and the standardised rate using the last national census of the population of Argentina (NCPA), from 2010. MATERIALS AND METHODS: Hospital Privado de Comunidad, Mar del Plata, Argentina, attends a closed population and is the sole healthcare provider for 17 614 people. Using the database pertaining to the Geriatric Care department, we identified all patients diagnosed with EOD between 1 January, 2005 and 31 December, 2011. EOD was defined as dementia diagnosed in patients younger than 65. RESULTS: The study period yielded 14 patients diagnosed with EOD out of a total of 287 patients evaluated for memory concerns. The crude annual incidence of EOD was 11 per 100 000/year (CI 95%: 6.25-19.1): 17 per 100 000 (CI 95%: 7.2-33.1) in men and 8 per 100 000 (CI 95%: 3.4-17.2) in women. We observed a statistically significant increase when comparing incidence rates between patients aged 21 to <55 years and ≥ 55 to <65 years (3 vs 22 per 100 000, P=.0014). The rate adjusted by NCPA census data was 5.8 cases of EOD habitants/year. CONCLUSION: This study, conducted in a closed population, yielded an EOD incidence rate of 11 per 100 000 inhabitants/year. To the best of our knowledge, this is the first prospective epidemiological study in Argentina and in Latin America.

This article reviews topics covered and discussed at the Meeting: "Vaccini e vaccinazioni. Migliorare l'oggi e preparare il domani", held in Genoa, Italy, on 12 September 2014. Data presented at the meeting, clearly showed that: 1) hepatitis B vaccination can confer long-term protection and there is no need for booster in immunocompetent vaccinees; 2) vaccination is highly effective in protecting population from clinical acute or chronic HBV infections, including hepatocellular carcinoma; 3) children vaccinated as infants with hexavalent vaccines maintain immunological memory 5 years after priming, but further studies are needed to assess whether immunity persists during the adolescence and adulthood when risk of exposure to HBV becomes higher; 4) the emergence of vaccine-escape mutants and Pol-gene mutants during antiviral therapy - which can result in changes in the S-gene - is of some concern, but at present there is no evidence that such mutants may pose a threat to the established programs of vaccination.
RESUMO
Blue whales (Balaenoptera musculus) were among the most intensively exploited species of whales in the world. As a consequence of this intense exploitation, blue whale sightings off the coast of Chile were uncommon by the end of the 20th century. In 2004, a feeding and nursing ground was reported in southern Chile (SCh). With the aim to investigate the genetic identity and relationship of these Chilean blue whales to those in other Southern Hemisphere areas, 60 biopsy samples were collected from blue whales in SCh between 2003 and 2009. These samples were genotyped at seven microsatellite loci and the mitochondrial control region was sequenced, allowing us to identify 52 individuals. To investigate the genetic identity of this suspected remnant population, we compared these 52 individuals to blue whales from Antarctica (ANT, n = 96), Northern Chile (NCh, n = 19) and the eastern tropical Pacific (ETP, n = 31). No significant differentiation in haplotype frequencies (mtDNA) or among genotypes (nDNA) was found between SCh, NCh and ETP, while significant differences were found between those three areas and Antarctica for both the mitochondrial and microsatellite analyses. Our results suggest at least two breeding population units or subspecies exist, which is also supported by other lines of evidence such as morphometrics and acoustics. The lack of differences detected between SCh/NCh/ETP areas supports the hypothesis that eastern South Pacific blue whales are using the ETP area as a possible breeding area. Considering the small population sizes previously reported for the SCh area, additional conservation measures and monitoring of this population should be developed and prioritized.

In this review we focused on the putative therapeutic effect of Hericium erinaceus extract in the treatment of pathologic conditions of the lower urinary tract in which intestinal inflammation may play a role. To this aim we reviewed the available evidence on pelvic cross-organ sensitization as a possible mechanism through which intestinal inflammation and dysbiosis may affect the lower urinary tract. Also, we reviewed the clinical and experimental evidence supporting the role of Hericium erinaceus extract as an anti-inflammatory agent highlighting the role of a number of putative mediators and mechanisms which might make this nutraceutical suitable for the management of 'difficult to treat' lower urinary tract disorders.

Background: Desmopressin is frequently used perioperatively in persons with nonsevere hemophilia A. However, increase in factor (F)VIII:C after desmopressin use is interindividually highly variable. Tachyphylaxis has only been reported in test setting for persons with hemophilia A, with a remaining response of approximately 70% after a second dose compared with that after a first dose. Objectives: To study tachyphylaxis of FVIII:C response after multiple administration(s) of desmopressin in perioperative persons with nonsevere hemophilia A. Methods: We studied FVIII:C levels after desmopressin before (day 0 [D0]) and on days 1 (D1) and 2 (D2) after surgery in 26 patients of the DAVID and Little DAVID studies. We studied tachyphylaxis by comparing the responses at D1 and D2 with that at D0. We also assessed the reproducibility of the D0 response in comparison to an earlier performed desmopressin test. Results: The median absolute FVIII:C increase was 0.50 IU/mL (0.35-0.74; n = 23) at D0, 0.21 IU/mL (0.14-0.28; n = 17) at D1, and 0.23 IU/mL (0.16-0.30; n = 11) at D2. The median percentage of FVIII increase after the second administration (D1) compared with the first (D0) was 42.9% (29.2%-52.5%; n = 17) and that of the third (D2) compared with the first (D0) was 36.4% (23.7%-46.9%; n = 11). The FVIII:C desmopressin response at D0 was comparable with the desmopressin test response in 74% of the patients. Conclusion: Tachyphylaxis in the surgical setting was considerably more pronounced than previously reported, with FVIII:C at D1 and D2 of 36% to 43% of the initial response. Our results may have important implications for monitoring repeated desmopressin treatment when used perioperatively.
RESUMO
INTRODUCTION: The annual incidence of seizure disorders rises sharply after the age of 60. Treatment is complicated by the normal physiological changes of aging, comorbid diseases, and polypharmacy. Despite this, approximately 80% of the patients become seizure-free. OBJECTIVES: The objectives of this study were to (1) analyze the outcome of a cohort of patients with newly-diagnosed epilepsy over the age of 65, (2) describe epilepsy etiology and seizure type, and (3) classify the outcome according to the latest ILAE classification proposal for drug-resistant epilepsy (2010). METHODS: All patients with newly-diagnosed epilepsy over the age of 65 who were evaluated in two different institutions were included. Seizures and epilepsy syndromes were classified according to the International League Against Epilepsy proposal (2010). Epilepsy outcomes were also analyzed according to the proposal of the ILAE Commission on Therapeutic Strategies (2010). RESULTS: One hundred and twenty-two patients were included with a median follow-up time of 15 months. Median age of diagnosis was 78 years. Seventy-seven patients (55%) had epilepsy of unknown cause, and 55 (45%) had structural-metabolic epilepsy. The proportions of seizure-free patients at 6, 12, 18, and 24 months were 90%, 77%, 74%, and 67%, respectively. Thirty percent of patients experienced adverse effects (AEs). We found a statistically significant trend toward a higher frequency of AEs as the number of concomitant medications rose and in younger patients. According to the 2010 ILAE classification proposal for drug-resistant epilepsy criteria, 55.8% of the patients were seizure-free, 12.3% had treatment failure, and 32% had undetermined seizure outcome. CONCLUSION: Patients with newly-diagnosed epilepsy after the age of 65 have very good chances of achieving seizure control with AED treatment. It seems that fulfilling the ILAE classification proposal for drug-resistant epilepsy (2010) criteria for seizure freedom was more difficult in our cohort. Older patients also seem to be more prone to suffering from AEs.

Viral hepatitis type E is highly endemic in many developing countries, where large water-borne epidemics caused by viral genotype 1 and - to a lesser degree - by genotype 2 cyclically occur, resulting in high morbidity and mortality, especially among pregnant women. In developed countries, the disease is usually diagnosed in travelers coming back from endemic countries, but an increasing number of sporadic locally acquired hepatitis cases caused by genotype 3 and 4 have recently been reported. The wide-spread distribution of HEV3 and HEV4 in domestic pigs, wild boars, deer, as well as in other mammals, suggests that infections caused by these genotypes may have a zoonotic source. HEV3 infection can evolve to chronic infection in immunosuppressed patients; in addition, it may be associated with neurological disorders and extrahepatic manifestations. Two recently developed recombinant vaccines have proved to be safe and effective. One of such vaccines has recently been licensed for use in China.

Breast cancer is the most common type of cancer worldwide. Diagnosing breast cancer relies on clinical examination, imaging and biopsy. A core-needle biopsy enables a morphological and biochemical characterization of the cancer and is considered the gold standard for breast cancer diagnosis. A histopathological examination uses high-resolution microscopes with outstanding contrast in the 2D plane, but the spatial resolution in the third, Z-direction, is reduced. In the present paper, we propose two high-resolution table-top systems for phase-contrast X-ray tomography of soft-tissue samples. The first system implements a classical Talbot-Lau interferometer and allows to perform ex-vivo imaging of human breast samples with a voxel size of 5.57 µm. The second system with a comparable voxel size relies on a Sigray MAAST X-ray source with structured anode. For the first time, we demonstrate the applicability of the latter to perform X-ray imaging of human breast specimens with ductal carcinoma in-situ. We assessed image quality of both setups and compared it to histology. We showed that both setups made it possible to target internal features of breast specimens with better resolution and contrast than previously achieved, demonstrating that grating-based phase-contrast X-ray CT could be a complementary tool for clinical histopathology.

The present study employed data collected during the Mycosands survey to investigate the environmental factors influencing yeasts and molds distribution along European shores applying a species distribution modelling approach. Occurrence data were compared to climatic datasets (temperature, precipitation, and solar radiation), soil datasets (chemical and physical properties), and water datasets (temperature, salinity, and chlorophyll-a concentration) downloaded from web databases. Analyses were performed by MaxEnt software. Results suggested a different probability of distribution of yeasts and molds along European shores. Yeasts seem to tolerate low temperatures better during winter than molds and this reflects a higher suitability for the Northern European coasts. This difference is more evident considering suitability in waters. Both distributions of molds and yeasts are influenced by basic soil pH, probably because acidic soils are more favorable to bacterial growth. Soils with high nitrogen concentrations are not suitable for fungal growth, which, in contrast, are optimal for plant growth, favored by this environment. Finally, molds show affinity with soil rich in nickel and yeasts with soils rich in cadmium resulting in a distribution mainly at the mouths of European rivers or lagoons, where these metals accumulate in river sediments.

We demonstrate the possibility of producing Au/SiO(2) core-shell nanoparticles by nanosecond laser irradiation of thin (5 and 20 nm) Au films on Si. The Au/Si eutectic reaction and dewetting process caused by the fast melting and solidification dynamics induced by the nanosecond laser irradiations are investigated as the origin of the formation of core-shell nanoparticles. Using several microscopic techniques (Rutherford backscattering spectrometry, scanning electron microscopy, atomic force microscopy, transmission electron microscopy, and energy filtered transmission electron microscopy) the formation and evolution of the core-shell structures are investigated as a function of the laser fluence in the 500-1500 mJ cm(-2) range for both film thicknesses. In particular, the mean height and diameter and surface density evolution of the core-shell structures are quantified and correlated to the laser fluence and Au film thickness.
RESUMO
INTRODUCTION: Chronic subdural hematoma in adults (CSDH) has a global crude incidence of 14.1/100,000 per year in our institution captive population. There is no single treatment protocol. In our hospital we choose a minimal invasive technique (trans-marrow puncture) without general anaesthesia due to the age of the population. A descriptive study of patients with CSDH and treatment results, including a laterality analysis, is presented. MATERIAL AND METHODS: We retrospectively searched patients with (CSDH) between January 1998 and May 2009. The diagnosis was made by neuroimaging techniques in all patients. The preferred treatment was trans-marrow puncture; exceptionally some patients were treated by burr holes or craniotomy. RESULTS: We found 127 patients. Age, gender, midline displacement, hospitalisation days, and number of procedures, were not a predictive factor of mortality in the first month. A slight majority (55%) of CSDH were on the left side, with no statistically significant difference. There were 6 (4.7%) deaths during hospitalisation. In our series cumulative mortality at six months was 11.8%. Markwalder scale at admission was not a predictive factor of statistically significant mortality. An 80% of the patients received trans-marrow puncture as single procedure was performed on 80% of the patients. CONCLUSIONS: The results of our study suggest that trans-marrow puncture is an acceptable procedure, with low mortality, and less hospitalisation days and complications. Mortality, associated mechanisms, age, gender, midline displacement are no different than in others previous publications. We found a higher frequency of hematomas to the left, as in other series. Meta-analysis studied need to be performed to determine more accurately the frequency of this dominance.

OBJECTIVE: The pandemic effects due to the coronavirus SARS-CoV-2 caused a health emergency. We decided to carry out a study with the aim to investigate the changes in patients' tendencies for admission to the emergency department for surgical diseases, and the related hospitalizations and urgent surgery rates. PATIENTS AND METHODS: We carried out a retrospective, observational study on patients who received emergency general surgery consultation at our University Hospital during the two COVID-19 pandemic periods and on the same dates one year before. The patients' demographic characteristics, their hospitalization in surgical department and the data about those who underwent urgent surgery were retrospectively recorded. RESULTS: In the period March-April 2020 there were 95 surgical visits recorded; among these patients, 25% required hospitalization and 12.63% underwent urgent surgery. In the period November-December-January 2020-2021 there were 156 surgical consultations, of which 35.26% required hospitalization and 21.15% underwent urgent surgery. In both considered periods we found that the number of surgical consultations decreased compared to the same periods of the previous year. Moreover, we found a higher rate of hospitalization and need for urgent surgery. CONCLUSIONS: We documented a significant reduction in the overall number of surgical consultations and an increase of hospitalization and urgent surgery rates.
