Abstract
BACKGROUND Among the post-surgical complications of lower wisdom teeth surgery, swelling is considered by patients one of the most impairing, with both social and biological influences and impacting patients' quality of life. Aim of the study was to evaluate the swelling following the osteotomy when performed with drilling burs versus piezo-electric instruments in the mandibular impacted third molar extraction, using a facial reconstruction software. MATERIALS AND METHODS A randomized, split-mouth, single-blind study was conducted on patients, ranging between 18 and 40 years of age, requiring lower third molars extraction and referred at the Oral Surgery Unit of the School of Dentistry of the University of Messina. Twenty-two patients were recruited during an 8 months period according to the following criteria: good general health conditions; bilateral, symmetrical, impacted third molars; no use of medication that would influence or alter wound healing; no temporomandibular joint disorder history; no smoking. All patients underwent bilateral surgical removal. For each patient, a facial scan was obtained prior to the surgical procedures. The two extractions were conducted performing, in a randomized way, osteotomy with rotatory burs or use of piezo surgical instruments. Facial scans were repeated at 3 and 7 days after the surgical procedures. Volumetric differences were calculated via superimposition using a dedicated software. The data obtained were processed using paired t-test. RESULTS The results obtained from our study showed no significant differences between two groups regarding post-operative swelling. To the best of our knowledge, this study represents the first experience of using an objective method that can be reproducible on the collection of patients' clinical parameters. CONCLUSIONS The 3D digital analysis, in the evaluation of facial swelling, is a technique of simple application, objective, reproducible, reliable, decreasing the variables of error. Based on these data, it is possible to conclude that piezo surgery is a safe way for performing the osteotomies during third molar surgery. However, regarding the post-operative swelling, it does not show an advantage over classical rotary instruments. TRIAL REGISTRATION Registered on ClinicalTrials.gov (ID: NCT05488028, on 04/08/2022). Approved by Ethical Committee of Messina: (ID 01-2020, on 27/04/2020).

Abstract
SARS-CoV-2 (severe acute respiratory syndrome Coronavirus-2) rapidly spread worldwide as COVID-19 (Coronavirus disease 2019), causing a costly and deadly pandemic. Different pulmonary manifestations represent this syndrome's most common clinical manifestations, together with the cardiovascular complications frequently observed in these patients. Ultrasound (US) evaluations of the lungs, heart, and lower limbs may be helpful in the diagnosis, follow-up, and prognosis of patients with COVID-19. Moreover, POCUS (point-of-care ultrasound) protocols are particularly useful for patients admitted to intensive care units. The present review aimed to highlight the clinical conditions during the SARS-CoV-2 pandemic in which the US represents a crucial diagnostic tool.

Abstract
Point-of-care ultrasonography (POCUS) represents a goal-directed ultrasound examination performed by clinicians directly involved in patient healthcare. POCUS has been widely used in emergency departments, where US exams allow physicians to make quick diagnoses and to recognize early life-threatening conditions which require prompt interventions. Although initially meant for the real-time evaluation of cardiovascular and respiratory pathologies, its use has been extended to a wide range of clinical applications, such as screening for deep-vein thrombosis and trauma, abdominal ultrasonography of the right upper quadrant and appendix, and guidance for invasive procedures. Moreover, recently, bedside ultrasounds have been used to evaluate the fluid balance and to guide decongestive therapy in acutely decompensated heart failure. The aim of the present review was to discuss the most common applications of POCUS in the emergency setting.

Abstract
Background The COVID-19 pandemic highlighted the significance of vaccination for older adults (OA), however, more health benefits could be gained with vaccination against influenza, pneumococcal disease, herpes zoster and tetanus as their uptake remains rather low. As healthcare professionals (HCP) play an important role in the vaccination decision making of OA, this study identifies obstacles in vaccination communication between HCP and OA. Methods 80 in-depth structured interviews have been conducted with HCPs in Hungary (HU), Italy (IT), the Netherlands (NL) and France (FR). Participants were general practitioners, medical specialists, public health physicians, occupational physicians, pharmacists, geriatricians, specialists elderly care and nurses. The interview included questions on HCPs’ perceptions regarding information provision to OA on vaccines. Data were analyzed cross-country, using thematic analysis. Results Preliminary results reveal that a factor hindering HCPs to initiate conversations with OA on vaccines was lack of time (FR, IT, HU, NL). In hospitals this was often due to (acute) clinical problems taking precedence over discussing vaccines (IT, NL). In ambulatory settings the high number of patients waiting to be seen prevented discussing vaccines with OA (HU). Moreover, HCPs sometimes forgot to discuss vaccines with OA (NL, HU, IT). Patient factors hindering the conversation of HCPs on OA vaccines were a negative attitude (IT, HU) and lack of understanding the information provided (IT, HU). Also, misinformation on vaccines (FR, HU), as well as anti-vax beliefs from patients (NL) or their relatives (FR, IT) hampered the conversation on vaccines. HCPs mentioned their need to learn communication skills to convince OA on vaccines (FR, IT, HU). Conclusions HCPs encounter various obstacles in communicating with OA about vaccines. Lack of time and not recognizing the opportunity to discuss vaccines are important barriers for initiating vaccine conversations. Key messages • Providing HCPs with communication strategies is important to support HCPs in discussing vaccines with OA. • Reminder systems are important to help HCPs remember address vaccination.

Abstract
Transcranial Doppler (TCD) ultrasonography is a rapid, noninvasive, real-time, and low-cost imaging technique. It is performed with a low-frequency (2 MHz) probe in order to evaluate the cerebral blood flow (CBF) and its pathological alterations, through specific acoustic windows. In the recent years, TCD use has been expanded across many clinical settings. Actually, the most widespread indication for TCD exam is represented by the diagnosis of paradoxical embolism, due to patent foramen ovale, in young patients with cryptogenic stroke. In addition, TCD has also found useful applications in neurological care setting, including the following: cerebral vasospasm following acute subarachnoid hemorrhage, brain trauma, cerebrovascular atherosclerosis, and evaluation of CBF and cerebral autoregulation after an ischemic stroke event. The present review aimed to describe the most recent evidences of TCD utilization from neurological to cardiological setting.

Abstract
INTRODUCTION The optimal anticoagulation strategy for venous thromboembolism (VTE) prevention among COVID-19 patients, hospitalized or in the community setting, is still challenging and largely based on real-world evidence. AREAS COVERED We analyzed real-world data regarding the safety and effectiveness of anticoagulant treatment, both parenteral and oral, for VTE prevention or atrial fibrillation (AF)/VTE treatment among COVID-19 patients. EXPERT OPINION The efficacy of low-molecular-weight heparin (LMWH) doses for VTE prevention correlates with COVID-19 disease status. LMWH prophylactic dose may be useful in COVID-19 patients at the early stage of the disease. LMWH intermediate or therapeutic dose is recommended in COVID-19 patients with an advanced stage of the disease. COVID-19 patients on VKAs therapy for atrial fibrillation (AF) and VTE should switch to NOACs in the community setting or LMWH in the hospital setting. No definitive data on de-novo starting of NOACs or VKAs therapy for VTE prevention in COVID-19 outpatients are available. In patients at high risk discharged after hospitalization due to COVID-19, thromboprophylaxis with NOACs may be considered.

Abstract
Aims The athlete's heart in power training is characterized by physiologic concentric remodeling. Our aim was to analyze left ventricular (LV) myocardial deformation and contractile reserve (CR) in top-level power athletes (PA) at rest and during exercise and their possible correlations with functional capacity. Methods Standard echo, lung ultrasound, and LV 2D speckle-tracking strain were performed at rest and during exercise in PA and in age- and sex-comparable healthy controls. Results 250 PA (male: 62%; 33.6 ± 4.8 years) and 180 age- and sex-comparable healthy controls were enrolled. LV ejection fraction (EF) at baseline was comparable between the two groups, while LV global longitudinal strain (GLS) was reduced in PA (GLS: -17.8 ± 2.4 in PA vs. -21.9 ± 3.8 in controls; P < 0.01). Conversely, myocardial work efficiency (MWE) did not show significant difference between the two groups (94.4 ± 3.2 in PA vs. 95.9 ± 4.6% in controls; P NS). At peak exertion during exercise stress echocardiography (ESE), PA showed better exercise capacity and peak VO2 consumption (51.6 ± 10.2 in EA vs. 39.8 ± 8.2 mL/Kg/min in controls, P < 0.0001), associated with augmented pulmonary artery systolic pressure (PASP). By multivariable analysis, MWE at rest was the most predictive factor of maximal watts (P < 0.0001), peak VO2, (P < 0.0001), PASP (P < 0.001), and number of B-lines (P < 0.001), all measured at peak effort. Conclusions In power athletes, MWE showed less load dependency than GLS. Normal resting values of MWE in PA suggest a physiological LV remodeling, associated with a better exercise capacity and preserved CR during physical stress.

Abstract
BACKGROUND Assessment of mucosal healing is important for the management of patients with inflammatory bowel disease (IBD), but endoscopy can miss microscopic disease areas that may relapse. Histological assessment is informative, but no single scoring system is widely adopted. We previously proposed an eight-item histological scheme for the easy, fast reporting of disease activity in the intestine. The aim of the present study was to evaluate the performance of our Simplified Histologic Mucosal Healing Scheme (SHMHS). METHODS Between April and May 2021 pathologists and gastroenterologists in Italy were invited to contribute to this multicenter study by providing data on single endoscopic-histological examinations for their IBD patients undergoing treatment. Disease activity was expressed using SHMHS (maximum score, 8) and either Simple Endoscopic Score for Crohn's Disease (categorized into grades 0-3) or Mayo Endoscopic Subscore (range 0-3). RESULTS Thirty hospitals provided data on 597 patients (291 Crohn's disease; 306 ulcerative colitis). The mean SHMHS score was 2.96 (SD = 2.42) and 66.8% of cases had active disease (score ≥ 2). The mean endoscopic score was 1.23 (SD = 1.05), with 67.8% having active disease (score ≥ 1). Histologic and endoscopic scores correlated (Spearman's ρ = 0.76), and scores for individual SHMHS items associated directly with endoscopic scores (chi-square p < 0.001, all comparisons). Between IBD types, scores for SHMHS items reflected differences in presentation, with cryptitis more common and erosions/ulcerations less common in Crohn's disease, and the distal colon more affected in ulcerative colitis. CONCLUSIONS SHMHS captures the main histological features of IBD. Routine adoption may simplify pathologist workload while ensuring accurate reporting for clinical decision making.

Abstract
Strain Marseille-Q1234T is a new species from the genus Halobacillus that was isolated in 2019 from a stool sample in a healthy Malian child <5 years old. Cells are Gram-positive and strictly halophilic bacilli. Strain Marseille-Q1234T exhibits 98.46% 16S rRNA gene sequence similarity to Halobacillus naozhouensis strain JSM 071068T (NR_116505.1), the phylogenetically closely related species with standing in nomenclature. Based on the phenotypic and phylogenetic evidence, OrthoANI values and results of the biochemical tests, the new species is named Halobacillus ihumii sp. nov., for which strain Marseille-Q1234T (= CSURQ1234) is proposed as the type strain.

Abstract
We are launching the Insights to Model Alzheimer's Progression in Real Life study in parallel with the Alzheimer Prevention Initiative Generation Program. This is a 5-year, multinational, prospective, longitudinal, non-interventional cohort study that will collect data across the spectrum of Alzheimer's disease. The primary objective is to assess the ability of the Alzheimer's Prevention Initiative Cognitive Composite Test Score and Repeatable Battery for the Assessment of Neuropsychological Status to predict clinically meaningful outcomes such as diagnosis of mild cognitive impairment or dementia due to Alzheimer's disease, and change in Clinical Dementia Rating - Global Score. This study is the first large-scale, prospective effort to establish the clinical meaningfulness of cognitive test scores that track longitudinal decline in preclinical Alzheimer's disease. This study is also expected to contribute to our understanding of the relationships among outcomes in different stages of Alzheimer's disease as well as models of individual trajectories during the course of the disease.

Abstract
BACKGROUND Prejudices and negative attitudes towards intellectual disabilities (IDs) may hinder social inclusion of ID individuals, limiting their well-being. This study investigated the psychometric characteristics of the Italian Modern and Classical Prejudices Scale (MCPS-IT) towards people with ID and the effects of gender, age and socio-economic status (SES) on prejudices. METHOD The MCPS-IT was administered to 474 adults (69% women, age range 18-70 years, M = 33.13) in conjunction with a questionnaire evaluating socio-demographic information (SES), the contact and the education about ID people and the social dominance orientation. RESULTS Results confirmed that Italian MCPS has a two-factor structure that measures in a reliable and valid way prejudice towards people with ID. Multivariate analyses of variance confirmed a weak gender difference in both scales and age differences in modern scale. No SES differences were found. CONCLUSION The Italian MCPS represents a valid scale that can be used to monitor the social context of people with ID.

Abstract
Diatom diazotroph associations (DDAs) are a widespread marine planktonic symbiosis between several diatom genera and di-nitrogen (N2)-fixing bacteria. Combining single cell confocal microscopy observations and molecular genetic approaches on individual field collected cells, we determined the phylogenetic diversity, distribution and evolution of the DDAs. Confocal analyses coupled with 3-D imaging re-evaluated the cellular location of DDA symbionts. DDA diversity was resolved by paired gene sequencing (18S rRNA and rbcL genes, 16S rRNA and nifH genes). A survey using the newly acquired sequences against public databases found sequences with high similarity (99-100%) to either host (18S rRNA) or symbiont (16S rRNA) in atypical regions for DDAs (high latitudes, anoxic basin and copepod gut). Concatenated phylogenies were congruent for the host and cyanobacteria sequences and implied co-evolution. Time-calibrated trees dated the appearance of N2 fixing planktonic symbiosis from 100-50Mya and were consistent with the symbiont cellular location: symbioses with internal partners are more ancient. An ancestral state reconstruction traced the evolution of traits in DDAs and highlight that the adaptive radiation to the marine environment was likely facilitated by the symbiosis. Our results present the evolutionary nature of DDAs and provide new genetic and phenotypic information for these biogeochemically relevant populations.

Abstract
Cosmic-ray muon radiography (muography), an imaging technique that can provide measurements of rock densities within the top few 100 m of a volcanic cone, has now achieved a spatial resolution of the order of 10 m in optimal detection conditions. Muography provides images of the top region of a volcano edifice with a resolution that is considerably better than that typically achieved with other conventional methods (i.e. gravimetric). We expect such precise measurements, to provide us with information on anomalies in the rock density distribution, which can be affected by dense lava conduits, low-density magma supply paths or the compression with the depth of the overlying soil. The MUon RAdiography of VESuvius (MURAVES) project is now in its final phase of construction and deployment. Up to four muon hodoscopes, each with a surface of roughly 1 m2, will be installed on the slope of Vesuvius and take data for at least 12 months. We will use the muographic profiles, combined with data from gravimetric and seismic measurement campaigns, to determine the stratigraphy of the lava plug at the bottom of the Vesuvius crater, in order to infer potential eruption pathways. While the MURAVES project unfolds, others are using emulsion detectors on Stromboli to study the lava conduits at the top of the volcano. These measurements are ongoing: they have completed two measurement campaigns and are now performing the first data analysis.This article is part of the Theo Murphy meeting issue 'Cosmic-ray muography'.

Abstract
Alzheimer's disease pathology begins decades before the onset of clinical symptoms. This provides an opportunity for interventional clinical trials to potentially delay or prevent the onset of cognitive impairment or dementia. CNP520 (a beta-site-amyloid precursor protein-cleaving enzyme inhibitor) is in clinical development for the treatment of preclinical Alzheimer's disease under the Alzheimer's Prevention Initiative Generation Program. The Alzheimer's Prevention Initiative is a public-private partnership intended to accelerate the evaluation of Alzheimer's disease prevention therapies. The Generation Program comprises two pivotal phase II/III studies with similar designs to assess the efficacy and safety of investigational treatments in a cognitively unimpaired population at increased risk for developing Alzheimer's disease based on age and apolipoprotein E (APOE) genotype (i.e., presence of the APOE ε4 allele). The program has been designed to maximize benefit to Alzheimer's disease research. Generation Study 1 (NCT02565511) and Generation Study 2 (NCT03131453) are currently enrolling; their key features are presented here.

Abstract
BACKGROUND Peginterferon induces off-treatment responses in approximately one-third of patients with hepatitis B e antigen (HBeAg)-positive chronic hepatitis B. AIM To develop an easy-to-use baseline prediction score to identify hepatitis B virus (HBV) genotype B-/C-infected HBeAg-positive Asian patients likely to respond to peginterferon alfa-2a. METHODS Generalised additive models, multiple logistic regression (MLR) analysis and internal validation methods were applied to data from 647 HBeAg-positive patients from China, Hong Kong and Taiwan to develop a scoring system to predict response 24 weeks after completing a 48-week course of peginterferon alfa-2a. RESULTS Five baseline factors (age, sex, alanine aminotransferase ratio, hepatitis B surface antigen (HBsAg) level and HBV DNA level) were retained in the final MLR for HBeAg seroconversion and used to develop a scoring system from 0 to 7. Among patients with scores of 0-1, 2-3, 4 or ≥5, HBeAg seroconversion was achieved in 6.4% (6/94), 23.0% (61/265), 36.4% (67/184) and 54.8% (57/104), respectively, and a combined response (HBeAg seroconversion plus HBV DNA <2000 IU/mL) in 5.3% (5/94), 12.8% (34/265), 25.0% (46/184) and 36.5% (38/104), respectively. Among patients with scores of 0-1, 2-3, 4 or ≥5, 57.0% (53/93), 12.3% (31/253), 3.4% (6/178) and 1.0% (1/100) had HBsAg ≥20 000 IU/mL at treatment Week 12; only 3/91 (3.3%) with HBsAg ≥20 000 IU/mL experienced a combined response at 24 weeks post-treatment (negative predictive value = 97% [88/91]). CONCLUSION A pre-treatment scoring system using readily available baseline characteristics identifies HBeAg-positive Asian patients likely to experience sustained HBeAg seroconversion after treatment with peginterferon alfa-2a.

Abstract
The properties of a new spontaneous tumor originating from the salivary gland of a C3H/He mouse were studied. The three different morphological patterns (adenocystic carcinoma, solid carcinoma and anaplastic adenocarcinoma), which concomitantly occured in the tumor, correspond to an ascending order of malignancy and indicate that the cells of the intercalated duct of the gland might be involved in the histogenesis. It has been observed that this new tumor retains its original characteristics when transplanted in syngeneic hosts after 153 serial transplant generations. No growth was observed in allogeneic hosts, the random-bred Swiss mice. The conversion of the solid tumor in to the ascites form was definitely not successful, even if the recipient mice were conditioned with X-rays and cortisone. Conditioning promoted the production of metastases in the lymphnodes and lungs.

Abstract
Large conductance voltage and calcium-activated potassium (MaxiK) channels are activated by membrane depolarization and elevated cytosolic Ca(2+). In the brain, they localize to neurons and astrocytes, where they play roles such as resetting the membrane potential during an action potential, neurotransmitter release, and neurovascular coupling. MaxiK channels are known to associate with several modulatory proteins and accessory subunits, and each of these interactions can have distinct physiological consequences. To uncover new players in MaxiK channel brain physiology, we applied a directed proteomic approach and obtained MaxiK channel pore-forming α subunit brain interactome using specific antibodies. Controls included immunoprecipitations with rabbit immunoglobulin G (IgG) and with anti-MaxiK antibodies in wild type and MaxiK channel knockout mice (Kcnma1(-/-)), respectively. We have found known and unreported interactive partners that localize to the plasma membrane, extracellular space, cytosol and intracellular organelles including mitochondria, nucleus, endoplasmic reticulum and Golgi apparatus. Localization of MaxiK channel to mitochondria was further confirmed using purified brain mitochondria colabeled with MitoTracker. Independent proof of MaxiK channel interaction with previously unidentified partners is given for GABA transporter 3 (GAT3) and heat shock protein 60 (HSP60). In human embryonic kidney 293 cells containing SV40 T-antigen (HEK293T) cells, both GAT3 and HSP60 coimmunoprecipitated and colocalized with MaxiK channel; colabeling was observed mainly at the cell periphery with GAT3 and intracellularly with HSP60 with protein proximity indices of ∼ 0.6 and ∼ 0.4, respectively. In rat primary hippocampal neurons, colocalization index was identical for GAT3 (∼ 0.6) and slightly higher for HSP60 (∼ 0.5) association with MaxiK channel. The results of this study provide a complete interactome of MaxiK channel the mouse brain, further establish the localization of MaxiK channel in the mouse brain mitochondria and demonstrate the interaction of MaxiK channel with GAT3 and HSP60 in neurons. The interaction of MaxiK channel with GAT3 opens the possibility of a role of MaxiK channel in GABA homeostasis and signaling.

Abstract
Strain FF3T was isolated from the skin-flora of a 39-year-old healthy Senegalese man. Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry did not allow any identification. This strain exhibited a 16S rRNA sequence similarity of 96.8% with Bacillus massiliensis, the phylogenetically closest species with standing nomenclature. Using a polyphasic study made of phenotypic and genomic analyses, strain FF3T was Gram-positive, aeroanaerobic and rod shaped and exhibited a genome of 4 068 720 bp with a G+C content of 37.03% that coded 3982 protein-coding and 67 RNA genes (including four rRNA operons). On the basis of these data, we propose the creation of Bacillus ndiopicus sp. nov.

Abstract
Ziram is a dimethyldithiocarbamate fungicide which can cause intraneuronal calcium (Ca(2+)) dysregulation and subsequently neuronal death. The signaling mechanisms underlying ziram-induced Ca(2+) dyshomeostasis and neurotoxicity are not fully understood. NCX3 is the third isoform of the sodium-calcium exchanger (NCX) family and plays an important role in regulating Ca(2+) homeostasis in excitable cells. We previously generated a mouse model deficient for the sodium-calcium exchanger 3 and showed that NCX3 is protective against ischemic damage. In the present study, we aim to examine whether NCX3 exerts a similar role against toxicological injury caused by the pesticide ziram. Our data show baby hamster kidney (BHK) cells stably transfected with NCX3 (BHK-NCX3) are more susceptible to ziram toxicity than cells transfected with the empty vector (BHK-WT). Increased toxicity in BHK-NCX3 was associated with a rapid rise in cytosolic Ca(2+) concentration [Ca(2+)]i induced by ziram. Profound mitochondrial dysfunction and ATP depletion were also observed in BHK-NCX3 cells following treatment with ziram. Lastly, primary dopaminergic neurons lacking NCX3 (NCX3(-/-)) were less sensitive to ziram neurotoxicity than wildtype control dopaminergic neurons. These results demonstrate that NCX3 genetic deletion protects against ziram-induced neurotoxicity and suggest NCX3 and its downstream molecular pathways as key factors involved in ziram toxicity. Our study identifies new molecular events through which pesticides (e.g. ziram) can lead to pathological features of degenerative diseases such as Parkinson's disease and indicates new targets to slow down neuronal degeneration.

Abstract
Cost-effective technologies are needed to reach the international greenhouse gas (GHG) reduction targets in many fields, including waste and biomass treatment. This work reports the effects of CO(2) capture from a combustion flue gas and its use in a newly-patented, two-phase anaerobic digestion (TPAD) process, to improve energy recovery and to reduce CO(2) emissions. A TPAD process, fed with urban wastewater sludge, was successfully established and maintained for several months at pilot scale. The TPAD process with injection of CO(2) exhibits efficient biomass degradation (58% VSS reduction), increased VFA production during the acidogenic phase (leading to VFA concentration of 8.4 g/L) and high biomethane production (0.350 S m(3)/kg(SSV); 0.363 S m(3)/m(3)(react) · d). Moreover, CO(2) intake in the acid phase has a positive impact on the overall GHG balance associated to biomethane production, and suggests an improved solution for both emission reduction and biomass conversion into biomethane.

Abstract
Psychological distress (PD) is common in patients with psoriasis but little is known about its evolution. The aim of this study is to assess the evolution of PD in psoriasis. For this purpose, 1,505 psoriatic patients, who had been previously enrolled in the PSYCHAE study, an observational multicenter Italian study, were re-evaluated after 6 and 12 months. Minor and major PD were assessed using the General Health Questionnaire (GHQ) and Brief Symptoms Inventory (BSI) questionnaires and coping using Brief COPE questionnaire. Minor PD was present in 46 percent of patients but halved during the study. Female gender, surface area, topical steroids, methotrexate, self-distraction, venting and behavioral disengagement were risk factors for minor PD; cyclosporine and humor were protective. Major PD was present in 11 percent of patients and remained stable. Female gender, venting, religion, behavioral disengagement and emotional support were risk factors for major PD; instrumental support was protective. In conclusion, the results obtained suggest that major PD remained stable after 12 months and that coping was a predictor of its evolution.

Abstract
PURPOSE To investigate whether propensity score (ps) methods could reasonably be applied to estimate the treatment effect on mortality, based on a comparatively small sample of patients with severe cutaneous adverse reactions (SCAR) and who come from different countries where physicians prefer different treatment schemes. METHODS Ps methods were applied to cope with confounding due to non-randomized treatment assignment for the analysis of the treatment data obtained in the case-control study EuroSCAR. For the study's purpose, the analysis focused on the comparison of the treatments: corticosteroids (STER) and supportive care only (SUPP). RESULTS 206 French and German patients were treated either with SUPP or STER. Imbalances between treatment groups as well as between the countries were recognized. Concerning the balance between the treatment groups no ps model for the full cohort was satisfying. In addition, the inclusion of a variable for patient's country led to a separation of the patients by country. Thus, we developed ps models for each country separately and estimated the treatment effects (France: odds ratio (OR) 0.52, 95% confidence interval (CI) 0.09-3.10, Germany: OR 0.23, CI 0.06-0.92, Overall: OR 0.33 CI 0.11-1.04). CONCLUSIONS The application of the ps methods was successful and provided valuable information. We could confirm the findings of the original analysis which was based on standard logistic regression, especially concerning the necessity of a country-specific analysis. The observed country differences in the estimated treatment effects were less pronounced and thus seemed to be more reasonable than those of the past analysis.

Abstract
Potentially viable therapeutic approaches for Duchenne muscular dystrophy (DMD) are now within reach. Indeed, clinical trials are currently under way. Two crucial aspects still need to be addressed: maximizing therapeutic efficacy and identifying appropriate and sensible outcome measures. Nevertheless, the end point of these trials remains painful muscle biopsy to show and quantify protein restoration in treated boys. In this study we show that PMMA/N-isopropil-acrylamide+ (NIPAM) nanoparticles (ZM2) bind and convey antisense oligoribonucleotides (AONs) very efficiently. Systemic injection of the ZM2-AON complex restored dystrophin protein synthesis in both skeletal and cardiac muscles of mdx mice, allowing protein localization in up to 40% of muscle fibers. The mdx exon 23 skipping level was up to 20%, as measured by the RealTime assay, and dystrophin restoration was confirmed by both reverse transcription-PCR and western blotting. Furthermore, we verified that dystrophin restoration also occurs in the smooth muscle cells of the dorsal skin arrector pili, an easily accessible histological structure, in ZM2-AON-treated mdx mice, with respect to untreated animals. This finding reveals arrector pili smooth muscle to be an appealing biomarker candidate and a novel low-invasive treatment end point. Furthermore, this marker would also be suitable for subsequent monitoring of the therapeutic effects in DMD patients. In addition, we demonstrate herein the expression of other sarcolemma proteins such as alpha-, beta-, gamma- and delta-sarcoglycans in the human skin arrector pili smooth muscle, thereby showing the potential of this muscle as a biomarker for other muscular dystrophies currently or soon to be the object of clinical trials.

Abstract
The simultaneous treatment of cardiovascular and urological diseases is at present discussed concerning indication and the increasing postoperative complications. Rarely these cases are observed with simultaneous critical diseases for both apparatuses thus conditioning the manner and timing of procedures. Authors report a case of sequential cardiosurgical and urological treatment in a patient affected by severe aortic stenosis and kidney neoplasm with bleeding. Authors performed the combined approach in the cardiosurgical department, starting with the aortic valve replacement with extracorporeal circulation (ECC) procedure and subsequently with the radical right nephrectomy. We believe that, with limitations according to each case, this approach can be taken into account in selected cases with severe cardiac valve disease refractory to medical therapy with persistent hematuria or bleeding.

Abstract
OBJECTIVE Our objectives were to determine the prevalence of psychological distress in a large sample of Italian patients with psoriasis; to establish whether disease severity and psychological distress are associated; to identify the strategies employed to cope with psoriasis; to evaluate the coping strategies employed by dermatologists; and to identify potential predictors of psychological distress. DESIGN Cross-sectional. SETTING Thirty-nine Italian dermatology centres. SUBJECTS One thousand five hundred and eighty (1580) patients with psoriasis. METHODS Minor psychological distress was evaluated using the General Health Questionnaire-12 (GHQ-12) and major psychopathological distress using the Brief Symptom Inventory (BSI); coping strategies were evaluated using the Brief COPE questionnaire; disease severity was evaluated using the body surface area index. RESULTS Patients were aged 44 +/- 13 years (mean +/- SD) and were mainly men (57%). Minor psychological distress was present in 46% of patients and major psychopathological distress in 11% of them. Both minor (54% vs. 40%, P < 0.0001) and major (17% vs. 7%, P < 0.0001) distress were more frequent in women than in men. The psychological status of women was worse than that of men independently from the extension of psoriasis. There was no association between the presence of distress and the treatment prescribed by dermatologists. Planning and active coping were the strategies most commonly employed by patients to cope with psoriasis, but there were between-gender differences. Most dermatologists employed a 'problem-orientated' attitude in caring for patients. CONCLUSIONS (i) Psychological distress was relatively frequent in our patients with psoriasis; (ii) female gender was the most important predictive factor for psychological distress; (iii) there was no association between psoriasis severity and psychological distress; (iv) planning and active coping were the coping strategies most frequently employed by patients; and (v) most dermatologists employed a problem-orientated attitude in caring for patients.

Abstract
The human immunodeficiency virus type 1 (HIV-1) Tat protein stimulates cell proliferation, inhibits apoptosis, displays angiogenic functions and is believed to be involved in the pathogenesis of Kaposi's sarcoma (KS) and other tumours arising in AIDS patients. Tat-transgenic (TT) mice, which constitutively express Tat in all tissues and organs, may therefore be predisposed to tumorigenesis. To test this hypothesis, we treated TT mice with urethane, a general carcinogen inducing tumours of various organs. The results indicate that, after injection of urethane, the incidence of lung tumours and lymphomas is not significantly different in the TT and control (CC) mice, whereas liver preneoplastic lesions and tumours show a significantly greater incidence in TT than in CC mice. This remarkable carcinogenic effect of urethane for the liver may be due to a tat-induced predisposition, manifested as a liver cell dysplasia (LCD), spontaneously affecting most of the TT mice. LCD may exert a promoting effect by stimulating proliferation of cell clones initiated by the mutagenic effect of urethane. In addition, LCD, which is associated with aneuploidy and chromosome instability, may enhance the progression to malignancy of the preneoplastic lesions induced by urethane. Interestingly, a significantly greater incidence of vascular ectasias and haemangiomas was detected in the liver of urethane-treated TT mice, most likely due to the marked angiogenic properties of Tat. This study suggests a role for Tat in the promotion and progression of tumours initiated by exogenous and endogenous carcinogens in HIV-1-infected patients, thereby contributing to the tumorigenesis in the course of AIDS.

Abstract
Anisakis pathology is due mainly to two mechanisms: allergic reactions (from isolated urticaria and angioedema to life-threatening anaphylactic shock associated with gastrointestinal symptoms or 'gastroallergic anisakiasis'), and direct tissue damage, due to invasion of the gut wall, development of eosinophilic granuloma, or perforation (gastric or intestinal anisakiasis). Anisakiasis is a misdiagnosed and underestimated cause of acute abdomen: most patients undergo laparotomy, and virtually no cases are diagnosed before surgery. In some cases, diagnosis is obtained accidentally during other pathologic investigations. We report a case of acute abdomen due to terminal ileum involvement. Microscopic examination of the resected segment showed the presence of helminthic sections consistent with larvae of Anisakis spp. A history of raw fish ingestion was recorded. Histopathologic features are illustrated. A short but up-to-date review of the literature on diagnostic devices (particularly imaging and serology), clinical aspects and therapy is presented.

Abstract
The immunotherapeutic potential of biologically active HIV-1 Tat protein coupled to autologous red blood cells (RBCs) was evaluated in a mouse model. HIV-1 Tat expressed in Escherichia coli and purified to homogeneity was found to be active in viral trans activation and efficiently internalised by monocyte-derived dendritic cells (MDDCs). The product of HIV-Tat biotinylation and coupling to RBCs by means of a biotin-avidin-biotin bridge, (RBC-Tat), showed no trans activation activity and was still efficiently internalized by MDDCs as compared to uncoupled Tat.Balb/c mice were then immunized with 10 microg of soluble Tat in complete Freund's adjuvant or with 40 ng of Tat coupled on RBCs surface and boosted at week 3, 6 and 25 with 5 microg soluble Tat in incomplete Freund's adjuvant or with 20 ng of RBC-coupled Tat, respectively. Anti-Tat antibody response was similar in both groups; however, 2/6 animals immunized with soluble Tat and 6/6 animals immunized with RBC-Tat developed anti-Tat neutralizing antibodies. In addition, at week 28 cytolytic anti-Tat CTLs were detected in all animals although they were slightly higher in mice immunized with RBC-Tat. These results indicate that RBC-mediated delivery of HIV-1 Tat, in amounts 250 times lower than soluble Tat, is safe and induces specific CTL responses and neutralizing antibodies.

Abstract
Cationic block copolymers, consisting of a poly(ethylene glycol) block and a block deriving from the poly(dimethylamino)ethyl methacrylate were prepared via a two-step procedure, based on the use of macroinitiators. By appropriately changing the experimental conditions and reacting the poly(dimethylamino)ethyl methacrylate block with iodo- or bromo-alkyl derivatives, a variety of ionic block copolymers with tuned physicochemical properties were prepared. These block copolymers are able to spontaneously self-assemble with plasmid DNA to produce oriented and shielded vectors, with physicochemical properties appropriate for in vivo applications. In addition, the formation of a complex between the cationic block copolymer and the plasmid DNA results in a nuclease resistance increase due to the stable nature of the complex.

Abstract
The toxic oil syndrome is an exogenously-induced autoimmune disease in humans, which is believed to be due to the accidental ingestion of oleic acid anilides. In a previously established murine model anilides-treated A/J mice developed a wasting disease after 1 week. Anilides-treated B10.S mice showed after 6 weeks a hyperimmunglobulinemia with autoantibody production, but no clinical symptoms. We now compared in vitro the effects of anilides on splenocytes and T cells in A/J and B10.S mice. Splenocyte proliferation was similar in both strains. After in vivo treatment of mice with anilides and in vitro restimulation, splenocytes of sick A/J mice showed a significant increase in splenocyte proliferation. Splenocytes from B10.S mice, however, had a suppressed baseline response and did not proliferate on restimulation. Adherent cells were necessary to induce proliferation in A/J mice-derived T cells. Apoptosis in splenocytes was significantly elevated in anilides-treated A/J and in B10.S mice as compared to saline-treated controls. These data show that anilides are able to affect the immune system in a strain-dependent way and may therefore take part in inducing the disease seen in humans and mice.

Abstract
OBJECTIVE The German Adjuvant Breast Cancer Study Group (GABG) conducts trials of preoperative chemotherapy in patients with primary breast cancer using a combination of doxorubicin and docetaxel (ADoc). - PATIENTS AND METHODS We conducted a parallel-grouped phase IIa-study with 42 patients with a conventionally dosed and a dose-dense ADoc-schedule (4 cycles of Doxorubicin 50 mg/m(2), Docetaxel 75 mg/m(2) i. v. day 1, q day 15 or 22; G-CSF day 3-15 only for the dose-dense schedule) and a randomized phase IIb-study (GEPARDO-Study) with 250 patients with ADoc +/- Tamoxifen. Biological factors were determined immunohistochemically on 197 core biopsies before treatment. A comparison to a sequential AC-Doc regimen including 913 patients has been completed recently. - RESULTS ADoc can be applicated on schedule in 93 % of all patients. The dose-dense regimen shows a tendency to more toxicity but also to more efficacy. The rate of complete pathological remissions (pCR) was 9.7 %. No difference was found between chemo- and chemoendocrine treatment. Clinically negative lymphnodes and a negative estrogen receptor status is predictive for a higher pCR-rate. To date no differences in toxicity could be found between ADoc and AC-Doc. - CONCLUSIONS The dose-dense ADoc regimen is well tolerated and highly effective as preoperative therapy of breast cancer.

Abstract
Human herpesvirus 8 (HHV-8) is found in immunoblastic B cells of patients with multicentric Castleman's disease (MCD) and, predominantly in a latent form, in primary effusion lymphoma (PEL) cells and Kaposi's sarcoma (KS) spindle cells. Recent studies have shown that upon reactivation, HHV-8 expresses factors that downregulate major histocompatibility class I proteins and coactivation molecules and that may enable productively infected cells to escape cytotoxic T lymphocytes and natural killer cell responses. One of these viral factors is encoded by open reading frame (ORF) K3. Here we show that in PEL cells, ORF K3 is expressed through viral transcripts that are induced very early upon virus reactivation, including bicistronic RNA molecules containing coding sequences from viral ORFs K3 and 70. Specifically, we found that a bicistronic transcript was expressed in the absence of de novo protein synthesis, thereby identifying a novel HHV-8 immediate-early gene product. Several features of the RNA molecules encoding the K3 product, including multiple transcriptional start sites, multiple donor splicing sites, and potential alternative ATG usage, suggest that there exists a finely tuned modulation of ORF K3 expression. By contrast, ORF K3 transcripts are not detected in the majority of cells present in KS lesions that are latently infected by the virus, suggesting that there are other, as-yet-unknown mechanisms of immune evasion for infected KS spindle cells. Nevertheless, because HHV-8 viremia precedes the development of KS lesions and is associated with the recrudescence of MCD symptoms, the prompt expression of ORF K3 in productively infected circulating cells may be important for virus pathogenesis. Thus, molecules targeting host or viral factors that activate ORF K3 expression or inactivate the biological functions of the K3 product should be exploited for the prevention or treatment of HHV-8-associated diseases in at-risk individuals.

Abstract
Textured implant surfaces are thought to enhance endosseous integration. Torque removal forces have been used as a biomechanical measure of anchorage, or endosseous integration, in which the greater forces required to remove implants may be interpreted as an increase in the strength of bony integration. The purpose of this study was to compare the torque resistance to removal of screw-shaped titanium implants having a dual acid-etched surface (Osseotite) with implants having either a machined surface, or a titanium plasma spray surface that exhibited a significantly more complex surface topography. Three custom screw-shaped implant types - machined, dual acid-etched (DAE), and titanium plasma sprayed (TPS) - were used in this study. Each implant surface was characterized by scanning electron microscopy and optical profilometry. One DAE implant was placed into each distal femur of eighteen adult New Zealand White rabbits along with one of the other implant types. Thus, each rabbit received two DAE implants and one each of the machined, or TPS, implants. All implants measured 3.25 mm in diameter x 4.00 mm in length without holes, grooves or slots to resist rotation. Eighteen rabbits were used for reverse torque measurements. Groups of six rabbits were sacrificed following one, two and three month healing periods. Implants were removed by reverse torque rotation with a digital torque-measuring device. Three implants with the machined surface preparation failed to achieve endosseous integration. All other implants were anchored by bone. Mean torque values for machined, DAE and TPS implants at one, two and three months were 6.00+/-0.64 N-cm, 9.07+/-0.67 N-cm and 6.73+/-0.95 N-cm; 21.86+/-1.37 N-cm, 27.63+/-3.41 N-cm and 27.40+/-3.89 N-cm; and 27.48+/-1.61 N-cm, 44.28+/-4.53 N-cm and 59.23+/-3.88 N-cm, respectively. Clearly, at the earliest time point the stability of DAE implants was comparable to that of TPS implants, while that of the machined implants was an order of magnitude lower. The TPS implants increased resistance to reverse torque removal over the three-month period. The results of this study confirm our previous results that demonstrated enhanced bony anchorage to dual acid-etched implants as compared to machined implants. Furthermore, the present results indicate that dual acid etching of titanium enhances early endosseous integration to a level which is comparable to that achieved by the topographically more complex TPS surfaces.
