Study Design Systematic review. Objective To assess the current literature regarding the relationship between the shoulder and the spine with regard to (1) overlapping pain pathways; (2) differentiating history, exam findings, and diagnostic findings; (3) concomitant pathology and optimal treatments; and (4) cervical spine-based etiology for shoulder problems. Methods A systematic literature search was performed according to the guidelines set forth by the Cochrane Collaboration. Studies were included if they examined the clinical, anatomical, or physiological overlap between the shoulder and cervical spine. Two reviewers screened and selected full texts for inclusion according to the objectives of the study. Quality of evidence was graded using OCEBM (Oxford Center for Evidence Based Medicine) and MINORS (Methodological Index for Nonrandomized Studies) scores. Results Out of 477 references screened, 76 articles were included for review and grouped into 4 main sections (overlapping pain pathways, differentiat referral patterns, shoulder kinematics, and examination techniques are invaluable to the clinician in making an appropriate diagnosis and guiding treatment. In this review, we present an algorithm for the identification and treatment of shoulder and cervical spine pathology. © The Author(s) 2019.Study Design Narrative review. Objectives Postoperative surgical site infections (SSIs) are among the most common acute complications in spine surgery and have a devastating impact on outcomes. They can lead to increased morbidity and mortality as well as greater economic burden. Hence, preventive strategies to reduce the rate of SSIs after spine surgery have become vitally important. The purpose of this article was to summarize and critically analyze the available evidence related to current strategies in the prevention of SSIs after spine surgery. Methods A literature search utilizing Medline database was performed. Relevant studies from all the evidence levels have been included. Recommendations to decrease the risk of SSIs have been provided based on the results from studies with the highest level of evidence. Results SSI prevention occurs at each phase of care including the preoperative, intraoperative, and postoperative periods. Meticulous patient selection, tight glycemic control in diabetics, smoking cessation, and screening/eradication of Staphylococcus aureus are some of the main preoperative patient-related preventive strategies. Currently used intraoperative measures include alcohol-based skin preparation, topical vancomycin powder, and betadine irrigation of the surgical site before closure. Postoperative infection prophylaxis can be performed by administration of silver-impregnated or vacuum dressings, extended intravenous antibiotics, and supplemental oxygen therapy. Conclusions Although preventive strategies are already in use alone or in combination, further high-level research is required to prove their efficacy in reducing the rate of SSIs in spine surgery before evidence-based standard infection prophylaxis guidelines can be built. © The Author(s) 2019.Study Design Retrospective cohort. Objective To understand which patient and surgical factors are predictive of an increased odds of undergoing an admission and a prolonged stay >2 days in an intensive care unit (ICU) following corrective surgery for pediatric deformity. Methods The 2016 American College of Surgeons-National Surgical Quality Improvement Program (ACS-NSQIP) Pediatric Spinal Fusion Procedure Targeted database records, merged with original 2016 ACS-NSQIP Pediatric file variables, were used for this study. Univariate and multivariate analyses were used to identify independent risk factors associated with admission, as well as a prolonged length of stay in the ICU following surgery. Results A total of 1398 (39.5%) patients required an ICU admission following the procedure-out of whom 416 (29.8%) stayed for more than 2 days. Following adjusted analysis, patient and surgical factors independently associated with an ICU admission were black/African American versus white race, anterior fusion, combined fusion, nonidiopathic scoliosis, preoperative ventilator dependence, asthma, having structural pulmonary abnormality, developmental delay, having a neuromuscular disorder, requiring nutritional support and a total operative time >270 minutes. The only significant factors associated with a prolonged length of ICU stay >2 days were preoperative ventilator dependence, nutritional support requirement, and undergoing anterior or combined fusion. Conclusions This study is the first of its kind to identify significant patient- and procedure-level factors associated with an ICU admission, and also explores predictors for a prolonged stay in the ICU. Surgeons can use this data to preoperatively counsel families and ensure postoperative course of care is appropriately planned ahead of time. © The Author(s) 2019.Study Design Retrospective cohort. Objective Facet fusion in minimally invasive spine surgery (MISS) may reduce morbidity and promote long-term construct stability. The study compares the maintenance of correction of thoracolumbar (TL) trauma patients who underwent MISS with facet fusion (FF) and without facet fusion (WOFF) and evaluates instrumentation loosening and failure. Methods TL trauma patients who underwent MISS between 2006 and 2013 were identified and stratified into FF and WOFF groups. To evaluate progressive kyphosis and loss of correction, Cobb angles were measured at immediate postoperative, short-term, and long-term follow-up. Evidence of >2 mm of radiolucency on radiographs indicated screw loosening. If instrumentation was removed, postremoval kyphosis angle was obtained. Results Of the 80 patients, 24 were in FF and 56 were in WOFF group. Between immediate postoperative and short-term follow-up, kyphosis angle changed by 4.0° (standard error [SE] 1.3°) in the FF and by 3.0° (SE 0.4°) in the WOFF group. The change between immediate postoperative and long-term follow-up kyphosis angles was 3.4° (S.E 1.1°) and 5.2° (S.E 1.6°) degrees in the FF and WOFF groups, respectively. Facet fusion had no impact on the change in kyphosis at short term (P = .49) or long term (P = .39). The screw loosening rate was 20.5% for the 80 patients with short-term follow-up and 68.8% for the 16 patients with long-term follow-up. There was no difference in screw loosening rate. Fifteen patients underwent instrumentation removal-all from the FF group. Conclusion FF in MISS does not impact the correction achieved and maintenance of correction in patients with traumatic spine injuries. https://www.selleckchem.com/GSK-3.html © The Author(s) 2019.

Background Hysteroscopic adhesiolysis (HA) remains the mainstay of treatment for intrauterine adhesions (IUA). In cases of moderate or severe IUA, the assistance of various adjunctive aids are usually sought to improve HA's success rate. Among these, intraoperative transabdominal ultrasound (TAS) is the most common; however, it has certain limitations. Preoperative three-dimensional transvaginal ultrasound (3D-TVUS) has been accepted as a non-invasive way to provide accurate information about the uterine cavity. This prospective, non-randomized controlled study will assess the effects of pre-operative 3D-TVUS prior to HA in improving the surgeon's intraoperative judgement. Methods A total of 362 patients, who met the inclusion criteria, aged between 18 and 45 years and diagnosed with moderate or severe IUA underwent HA at our hospital from March 2018 to December 2018. Participants were divided into 2 groups; the study group; n=182 performed 3D-TVUS evaluation prior to HA, and the control group; n=180 underwenrly visible fallopian tube ostia (P less then 0.0001) following HA. Conclusions This study showed that preoperative 3D-TVUS evaluation helped the hysteroscopists with their intraoperative decision-making while carrying out HA. In comparison to those who did not perform preoperative 3D ultrasound, those who underwent 3D-TVUS evaluation had a better surgical success rate in retrieving the fallopian tube ostia and the restoration of normal uterine cavity morphology. 2020 Annals of Translational Medicine.

But there are neither published reports regarding the difference in diagnosis and treatment of such patients compared to those with CI only, nor any report about their prognosis. This study aimed to preliminary the alteration in diagnostic and curative aspects of these patients, so as to provide a certain reference for the clinical management of such conditions. Methods Ten patients with CI combined with moderate to severe IUAs were diagnosed, treated and followed up at the Third Xiangya Hospital of Central South University from September 2017 to August 2019, their medical records and the pregnancy outcomes were retrospectively analyzed. Results All 10 patients had a previous history of typical painless cervical dilatation during the second trimester. All patients were moderate to severer IUAs, and the mean AFS score of IUAs was 9.80±1.08 (range, 8 to 12). Preoperatively, inlower uterine segment IUAs, it is necessary to separate the adhesion prior to evaluating the cervical competency with the No. 7 Hegar dilator, to confirm the diagnosis. However, when the cervix is too loose, laparoscopic cervical cerclage is exceptionally carried out first and then IUAs is treated. Pre-pregnancy laparoscopic cervical cerclage has a good prognosis in patients with CI complicated by moderate to severe IUAs. 2020 Annals of Translational Medicine.

Methods HEGCs were isolated from the endometrial biopsies and exposed to different dose of GH (0, 50, 100, and 200 ng/mL). Cell proliferation and cell cycle assay, migration assay was performed to investigate the growth and motivation of hEGCs, respectively. Reverse transcription-polymerase chain reaction (RT-PCR), immunocytochemistry (ICC), and western blot (WB) were processed to investigate its related gene or protein expression. Results The results revealed that GH administration promoted the proliferation, cell cycle, migration, and growth hormone receptors (GHRs) expression of the hEGC. We further inhibited GHRs with AG490, and the inhibitor reversed the effects of GH on cell growth, motion, and the activation of GHR and STAT3/5. Conclusions GH promoted hEGCs proliferation and motion, which is GHR-JAK-STAT3/5 signaling pathway-dependent. https://www.selleckchem.com/products/ms-275.html These findings reveal the essential roles of GH in the hEGCs growth and provide evidence for potential GH therapy in intrauterine adhesion (IUA) treatment. 2020 Annals of Translational Medicine.

The microorganisms of the female reproductive tract play an important role in its health and disease. The imbalance of immune regulation caused by the imbalance of reproductive tract dysbacteriosis may be an important link in the formation mechanism of uterine cavity adhesion. Methods We prospectively enrolled 30 patients diagnosed with IUA and 30 women with a history of intrauterine surgery, but without IUA, as control subjects. All participants were diagnosed with hysteroscopy while two swabs-one being leucorrhea drawn from the middle of the vagina and the other being cervical mucus drawn from the cervical canal-were taken. The bacterial load and community were identified by 16S rDNA quantitative polymerase chain reaction and pyrosequencing. Immunocytokines in serum were quantitatively detected by human T-helper cytokine kit. TheIUA. 2020 Annals of Translational Medicine. All rights reserved.Background Intrauterine adhesion (IUA) is caused by adhesion of the uterine cavity due to the damage of endometrium. Hysteroscopic adhesiolysis (HA) is the main treatment. The objective of the study was to investigate the obstetrical outcome in the third trimester of women who previously underwent HA. Methods We performed a retrospective cohort study in the university-affiliated hospital. A total of 146 women with a history of HA who had given birth in their third trimester from May 2012 to May 2019 were enrolled (study group), while 292 women with a negative history of HA were matched for maternal age, gravidity, parity, and delivery year. The parameters of obstetrics and infants were investigated to evaluate the change in the third trimester of women with a history of HA. Results There was no significant difference between study and control groups in gestational weeks, nor in fetal gender distribution, birth weight, Apgar score, fetal distress, and neonatal intensive care unit (NICU) admissions after delivery (P>0.

bleekeri were discussed. In addition, a large number of long non-coding RNAs (lncRNAs) and simple sequence repeats (SSRs) were obtained in the H. bleekeri transcriptome. The present study will provide basic genomic information for H. bleekeri and for further research on analysing the characteristics of both the innate and adaptive immune systems of this critically endangered species.Cathelicidins are an important family of antimicrobial peptides (AMPs), which play pivotal roles in vertebrate immune responses against microbial infections. They are regarded as potential drug leads for the development of novel antimicrobial agents and three related drugs have been developed into clinical trials. Thus, it is meaningful to identify more cathelicidins from vertebrate species. Cathelicidins from ranid frogs possess special structural characteristics and activities, but to date only 12 ranid frog cathelicidins have been identified. In the present study, two novel cathelicidins (PN-CATH1 and 2) were identified from the black-spotted frog, Pelophylax nigromaculata. PN-CATHs possess low sequence similarity with the known cathelicidins. They exhibited moderate, but broad-spectrum and rapid antimicrobial activities against the tested bacteria. They kill bacteria by mainly inducing bacterial membrane disruption and possibly generating intracellular ROS formation. They also possess potent anti-biofilm and persister cell killing activity, indicating their potential in combating infections induced by biofilms-forming bacteria. Besides direct antimicrobial activity, they exhibited potent anti-inflammatory activity by effectively inhibiting the LPS-induced production of pro-inflammatory cytokines in mouse macrophages, which could be partly ascribed to their direct LPS-neutralizing ability. Furthermore, PN-CATHs demonstrated powerful in vitro free radical scavenging activities. Ultraviolet radiation significantly increased their in vivo gene expression in frog skin. Meanwhile, they possess weak cytotoxic activity and extremely low hemolytic activity. PN-CATHs represent the first discovery of cathelicidins family AMPs with both potent anti-infective and antioxidant activities. The discovery of PN-CATHs provides potential peptide leads for the development of novel anti-infective and antioxidant drugs.Tilapia lake virus (TiLV; genus Tilapinevirus, family Amnoonviridae) is a recently characterised enveloped virus with a linear, negative-sense single-stranded RNA genome, which causes high mortality in tilapia species. In the present study, we demonstrated that zebrafish (Danio rerio) larvae are susceptible to TiLV infection upon systemic injection. TiLV replicated in zebrafish larvae and caused their high mortality (of about 70%). Histopathological examination revealed that TiLV infection caused pathological abnormalities in zebrafish larvae that were well visible within the brain. https://www.selleckchem.com/products/OSI-906.html Moreover, gene expression analysis revealed that TiLV infection induced up-regulation of the expression of the immune-related genes encoding pathogen recognition receptors involved in sensing of viral dsRNA (rig-I (ddx58), tlr3, tlr22), transcription factors (irf3, irf7), type I interferon (infϕ1), antiviral protein (mxa), and pro-inflammatory cytokine (il-1β). We also demonstrated the protective role of the recombinant zebrafish IFNϕ1 on the survival of zebrafish larvae during TiLV infection. Our results show the importance of type I IFN response during TiLV infection in zebrafish larvae and demonstrate that zebrafish is a good model organism to study interactions between TiLV - a newly emerging in aquaculture virus, and fish host.Bid is a pro-apoptotic BH3-only member of the Bcl-2 superfamily that functions to link the extrinsic apoptotic pathway and the mitochondrial amplification loop of the intrinsic pathway. In this study, the expression and functions of Chinese giant salamander (Andrias davidianus) Bid (AdBid) were investigated. The AdBid cDNA sequence contains an open reading frame (ORF) of 576 nucleotides, encoding a putative protein of 191 aa. AdBid possesses the conserved BH3 interacting domain and shared 34-52% sequence identities with other amphibian Bid. mRNA expression of AdBid was most abundant in muscle. The expression level of AdBid in Chinese giant salamander muscle, kidney and spleen significantly increased after Chinese giant salamander iridovirus (GSIV) infection. Additionally, a plasmid expressing AdBid was constructed and transfected into the Chinese giant salamander muscle cell line (GSM cells). The morphology and cytopathic effect (CPE) and apoptotic process in AdBid over-expressed GSM cells was significantly enhanced during GSIV infection compared with that in control cells. Moreover, a higher level of the virus major capsid protein (MCP) gene copies and protein synthesis was confirmed in the AdBid over-expressed cells. These results indicated that AdBid played a positive role in GSIV induced apoptosis and the viral replication. This study may contribute to the better understanding on the infection mechanism of iridovirus-induced apoptosis.Signaling 'bias' is a phenomenon whereby the natural allosteric probe dependence of seven transmembrane receptors allows different receptor conformations (stabilized by different agonists) to activate some signaling pathways (coupled to pleiotropically coupled receptors) more than others at the expense of those other pathways. There are a number of relevant scenarios where such an activity could be therapeutically beneficial therefore there are practical reasons why this property of receptors should be exploited. This paper discusses recent ideas around attempts to harness this potentially useful idea and also the limitations around the current methods available to do so. Specifically, the determination of a quantitative value for the receptor bias of a given agonist that may translate to useful in vivo has been particularly elusive and studies need to be directed to solving this problem.How the nervous system regulates bone remodeling is an exciting area of emerging research in bone biology. Accumulating evidence suggest that neurotransmitter-mediated inputs from neurons may act directly on osteoclasts. Dopamine is a neurotransmitter that can be released by hypothalamic neurons to regulate bone metabolism through the hypothalamic-pituitary-gonadal axis. Dopamine is also present in sympathetic nerves that penetrate skeletal structures throughout the body. It has been shown that dopamine suppresses osteoclast differentiation via a D2-like receptors (D2R)-dependent manner, but the intracellular secondary signaling pathway has not been elucidated. In this study, we found that cAMP-response element binding protein (CREB) activity responds to dopamine treatment during osteoclastogenesis. Considering the critical role of CREB in osteoclastogenesis, we hypothesize that CREB may be a critical target in dopamine's regulation of osteoclast differentiation. We confirmed that D2R is also present in RAW cells and activated by dopamine.

e. size and numerical density of the osteocyte lacunae. The correlated histological results obtained on the same samples confirmed these observations, also adding information related to non-mineralized tissues. Despite its demonstrative nature, it was concluded that the proposed method was powerful in studying jawbone remodeling because it revealed a direct correlation of its rate with the lacunar density, as achieved by the analysis of the osteocyte lacunar network, and an inverse correlation with the local bone mineral density, as revealed with the Roschger approach.Hepatic fibrosis is a major consequence of chronic liver disease such as non-alcoholic steatohepatitis which is undergoing a dramatic evolution given the obesity progression worldwide, and has no treatment to date. Hepatic stellate cells (HSCs) play a key role in the fibrosis process, because in chronic liver damage, they transdifferentiate from a "quiescent" to an "activated" phenotype responsible for most the collagen deposition in liver tissue. Here, using a diet-induced liver fibrosis murine model (choline-deficient amino acid-defined, high fat diet), we characterized a specific population of HSCs organized as clusters presenting simultaneously hypertrophy of retinoid droplets, quiescent and activated HSC markers. We showed that hypertrophied HSCs co-localized with fibrosis areas in space and time. Importantly, we reported the existence of this phenotype and its association with collagen deposition in three other mouse fibrosis models, including CCl4-induced fibrosis model. Moreover, we have also shown its relevance in human liver fibrosis associated with different etiologies (obesity, non-alcoholic steatohepatitis, viral hepatitis C and alcoholism). In particular, we have demonstrated a significant positive correlation between the stage of liver fibrosis and HSC hypertrophy in a cohort of obese patients with hepatic fibrosis. These results lead us to conclude that hypertrophied HSCs are closely associated with hepatic fibrosis in a metabolic disease context and may represent a new marker of metabolic liver disease progression.Riverbed terracing has been introduced in ancient times to retain water and soil, to reduce hydrological connectivity and erosion and to increase primary and secondary productivity of agro-ecological systems. These presently abandoned human-made landscapes have become novel ecosystems and a potential source of ecosystem services to humans in drylands. We use a mathematical-modeling approach to study factors that regulate terraced riverbeds and affect community and ecosystem attributes such as productivity, functional diversity and resilience to droughts. We introduce a model that captures the relationships between rainfall pattern, runoff coupling between adjacent terraces, and vegetation growth, taking into account competition for water and light. We found that a large number of weak rainfall events results in lower total biomass and functional diversity across the terraced riverbed compared with a few strong rainfall events. We further analyzed the filtering of species traits from pools of functional groups that make different tradeoffs between investment in above-ground biomass to capture canopy resources and investment in below-ground biomass to capture soil resources. Pools characterized by concave tradeoffs give rise to higher functional diversity, lower biomass production and lower resilience to droughts, as compared with convex pools. New empirical studies are needed to test these model predictions.Recycling cycles cause a decrease in mechanical paper properties due to cellulose fiber degradation. The use of cellulose micro/nanofibers (CMF/CNF) to reinforce paper strength has been well studied, although it has been found to have negative effects on drainage. However, the application of CMF/CNF as paper reinforcement is affected by the nanocellulose type. Thus in this study mechanical and chemical treatments in CNF production were compared. Old corrugated container (OCC) pulp used to produce recycled cartonboard was reinforced with 1) CMF from never-dried northern bleached softwood kraft pulp (NBSK) highly refined in a 16-inch low consistency refiner at 1200 rpm and 25 kW of net power; and 2) CNF from NBSK pulp treated by TEMPO-mediated oxidation and homogenization at 600 bars. CMF/CNF and OCC were pulped at the same time and handsheets formed with cationic starch (CS) as retention system. Mechanical, drainage and flocculation properties were evaluated and compared. Data were also compared with other sources of TEMPO CNF. Results show an improvement in mechanical properties, drainage and flocculation when OCC is reinforced with CMF obtained with LCR. Therefore, high fibrillation was not necessary to improve mechanical paper or cardboard properties.Post-conflict affiliations initiated by bystanders (bystander affiliation) toward aggressors or victims have been suggested to represent the function of conflict management in some social living species. https://www.selleckchem.com/products/Rapamycin.html However, the function of bystander affiliations toward aggressors and victims has not been examined in marine mammals. In the present study, we investigated the function of bystander affiliations to aggressors and victims in bottlenose dolphins self-protection, the substitute of reconciliation, social facilitation and tension relief of opponents. These bystander affiliations did not reduce post-conflict attacks by former opponents against group members. Bystander affiliation to aggressors tended to be performed by a bystander who had an affiliative relationship with the aggressor but not with the victim. Bystander affiliation to victims also tended to be initiated by a bystander who had an affiliative relationship with the victim but not the aggressor and was close to former opponents at the end of aggressions. Affiliation among group members who stayed near former opponents during aggressions did not increase after aggressions compared to that under control conditions. Renewed aggressions between former opponents decreased after bystander affiliations in our previous study. Bystanders who showed social closeness to former opponents may initiate bystander affiliation toward their affiliative former opponents because they may feel emotion, such as anxiety and excitement, of former opponents. Bystander affiliation toward aggressors and victims may function as tension relief between former opponents. Bystanders of bottlenose dolphins, who may have a relaxed dominant style, might initiate post-conflict affiliation to affiliative individuals unaffected by the dominance relationships among them, unlike despotic species.

Bystander affiliation toward aggressors and victims may function as tension relief between former opponents. Bystanders of bottlenose dolphins, who may have a relaxed dominant style, might initiate post-conflict affiliation to affiliative individuals unaffected by the dominance relationships among them, unlike despotic species.

Protein O-GlcNAcylation is a dynamic post-translational modification involving the attachment of N-acetylglucosamine (GlcNAc) to the hydroxyl groups of Ser/Thr residues on numerous nucleocytoplasmic proteins. Two enzymes are responsible for O-GlcNAc cycling on substrate proteins O-GlcNAc transferase (OGT) catalyzes the addition while O-GlcNAcase (OGA) helps the removal of GlcNAc. O-GlcNAcylation modifies protein functions; therefore, dysregulation of O-GlcNAcylation affects cell physiology and contributes to pathogenesis. To maintain homeostasis of cellular O-GlcNAcylation, there exists feedback regulation of OGT and OGA expression responding to fluctuations of O-GlcNAc levels; yet, little is known about the molecular mechanisms involved. https://www.selleckchem.com/products/azd9291.html In this study, we investigated the O-GlcNAc-feedback regulation of OGT and OGA expression in lung cancer cells. Results suggest that, upon alterations in O-GlcNAcylation, the regulation of OGA expression occurs at the mRNA level and likely involves epigenetic mechanisms, while modulation of OGT expression is through translation control. Further analyses revealed that the eukaryotic translation initiation factor 4E-binding protein 1 (4E-BP1) contributes to the downregulation of OGT induced by hyper-O-GlcNAcylation; the S5A/S6A O-GlcNAcylation-site mutant of 4E-BP1 cannot support this regulation, suggesting an important role of O-GlcNAcylation. The results provide additional insight into the molecular mechanisms through which cells may fine-tune intracellular O-GlcNAc levels to maintain homeostasis.The coronavirus disease 2019 (COVID-19) pandemic has had a substantial impact on the provision of medical healthcare. Due to an increased risk of severe acute respiratory syndrome coronavirus 2 (SARS-Cov-2) transmission, elective surgical treatment has been suspended in many centers. The effects of COVID-19 in the early post-operative period after esophagectomy remains unknown. In this report, we present three cases of patients diagnosed with esophago-gastric junction cancer who were scheduled for elective esophagectomy with a curative intention during second wave of COVID-19 pandemic in a single high-volume tertiary center. Despite all available safety measures, one of the patients developed COVID-19 pneumonia on post-operative day two, leading to an impaired respiratory function and increased pleural fluid collection from the chest tube, resulting in a prolonged time of hospital stay. Finding a good balance between the COVID-19-related perioperative risks and consequences of delaying surgical treatment in patients diagnosed with esophago-gastric cancer is a challenge. In order to achieve the best possible outcome, care must be taken to ensure availability of necessary treatment options and to reduce the risk of SARS-Cov-2 transmission perioperatively. Population groups to be prioritized for COVID-19 vaccinations in the U.S. have been determined at the Federal level, but there is variation in how States have implemented guidance. This review examines how the position of population groups in vaccine priority lists varies between Federal guidance and State practice. An online search of State vaccination prioritization plans was conducted. Data were extracted on each population group included and their relative position. A standardized ranking method was applied to provide a directional measure of variability in prioritization between State and Federal guidance, for each population group. Healthcare workers and those in long-term care facilities were largely prioritized in line with Federal guidance. Aside from early education staff, essential workers were often excluded at State level. Almost all States included the 65-74 year age group and most assigned them to a higher position than recommended in Federal guidance. Those with underlying medical conditions were similarly highly prioritized, although there was more variability across States. Some socially vulnerable groups (not included in Federal guidance) were highly prioritized by many States. The prioritization of groups for COVID-19 vaccination has been highly variable despite clear Federal guidance. Future guidance must be relevant to local needs, values, and constraints, to minimize any unwarranted heterogeneity in vaccine access across populations. The prioritization of groups for COVID-19 vaccination has been highly variable despite clear Federal guidance. Future guidance must be relevant to local needs, values, and constraints, to minimize any unwarranted heterogeneity in vaccine access across populations.Worldwide, the COVID-19 pandemic has caused a decline in blood donations, between 30% and 70% in some of the most affected countries. In Spain, during the initial eight weeks after the State of Emergency was decreed on 14 March 2020, in the weekly reports of the Health Ministry, an average decrease of 20% was observed between 11 and week 25 compared with the 2018 donation. We aimed to investigate the impact of the COVID-19 pandemic on blood donations and blood distribution in four autonomous communities, and to explore the evolution of the consumption of blood components (BCs) in ten hospitals of six autonomous communities. We performed a prospective study of grouped cohorts on the donation and distribution of blood in four regional transfusion centers in four autonomous communities in Spain, and a retrospective study of the consumption of blood components in ten hospitals in six autonomous communities. Regarding donations, there was no significant decrease in donations, with differences between autonomous communities, which started between 1 and 15 March 2020 (-11%). The increase in donations in phase II (from 26 May 2020) stands out. Regarding consumption, there was a significant reduction in the consumption of packed red blood cells (RBCs) (24.5%), plasma (45.3%), and platelets (25.3%) in the central period (16 March-10 May). The reduction in the consumption of RBCs was significant in the period from 1-15 March. Conclusions The COVID-19 pandemic has affected the donation and consumption of BCs.Muscle oxygen consumption could provide information on oxidative metabolism in women soccer players. Therefore, the objective of this study was to analyze muscle oxygenation dynamics during repeated sprint ability (RSA) (8 sprint × 20 s recovery) by near-infrared spectroscopy (NIRS). The sample was made up of 38 professional women soccer players. To measure the external load, the best time, worst time, average time, individual speed, sprint decrement, and power were assessed. In connection with the internal load, the desaturation (sprint) and re-saturation (recovery) rates, as well as the oxygen extraction (∇%SmO2) in the gastrocnemius muscle and maximum heart rate (%HRmax) were measured. A repeated measures statistic was applied based on the inter-individual response of each subject from the baseline versus the other sprints, with linear regression and nonlinear regression analyses between variables. There was an increase in the SmO2 desaturation rate after four sprints (Δ = 32%), in the re-saturation rate after six sprints (Δ = 89%), and in ∇%SmO2 after four sprints (Δ = 72.

Transplantation significantly reduced the total number of follicles with the greatest impact observed at the primordial follicle stage. We report that NMN did not prevent this loss. While NMN did not significantly impact the proportion of apoptotic follicles, NMN normalised PCNA expression at the primordial and intermediate stages but not at later stages. In conclusion, NMN administration did not prevent ovarian follicle loss under the conditions of this study.Progesterone, which is secreted from the corpus luteum, is indispensable for the establishment and maintenance of pregnancy. The orphan nuclear receptor subfamily 5 group A member 2 (NR5A2) is a regulator of murine luteinization, but neither its regulation nor its role in the fully differentiated, mature corpus luteum (CL) have been described. Therefore, the goal of this study was to profile abundance and investigate the regulation and functions of NR5A2 in the bovine CL. Treatment of cultured luteal steroidogenic cells with a pharmacological inhibitor of NR5A2 decreased progesterone production and tended to decrease abundance of HSD3B1 mRNA. Luteal NR5A2 mRNA increased and NR5A2 protein tended to increase between days 4 and 6 of the estrous cycle, coincident with increased steroidogenic capacity of the CL. Luteal NR5A2 mRNA decreased by 8 h after prostaglandin (PG) F2A injection. During early pregnancy, luteal NR5A2 mRNA was less on days 20 and 23 compared to day 14, but protein abundance did not change. Neither 1 nor 10 ng/mL interferon tau (IFNT) altered NR5A2 abundance in cultured luteal steroidogenic cells, but 10 ng/mL PGF2A decreased NR5A2. Because of discrepancies between mRNA and protein abundance of NR5A2, regulation by miRNA that changed during early pregnancy was investigated. miR-27b-3p, miR-432-5p, and miR-369-3p mimics decreased NR5A2 protein abundance and miR-369-3p also inhibited progesterone production. Overall, the results of this study show that NR5A2 may be maintained by miRNA during early pregnancy and may be an important regulator of luteal progesterone production. COVID-19 has affected more than 180 countries and is the first known pandemic to be caused by a new virus. COVID-19's emergence and rapid spread is a global public health and economic crisis. https://www.selleckchem.com/products/Paclitaxel(Taxol).html However, investigations into the disease, patient-tracking mechanisms, and case report transmissions are both labor-intensive and slow. The pandemic has overwhelmed health care systems, forcing hospitals and medical facilities to find effective ways to share data. This study aims to design a global infectious disease surveillance and case tracking system that can facilitate the detection and control of COVID-19. The International Patient Summary (IPS; an electronic health record that contains essential health care information about a patient) was used. The IPS was designed to support the used case scenario for unplanned cross-border care. The design, scope, utility, and potential for reuse of the IPS for unplanned cross-border care make it suitable for situations like COVID-19. The Fast Healthcare Interoperability unknown virus. This system could be an effective tool for global collaboration in evidence-based efforts to fight COVID-19. We created the IPS of infectious diseases for physicians treating patients with COVID-19. Our system can help health authorities respond quickly to the transmission and spread of unknown diseases, and provides a system for information retrieval on disease transmission. In addition, this system can help researchers form trials and analyze data from different countries. A common forum to facilitate the mutual sharing of experiences, best practices, therapies, useful medications, and clinical intervention outcomes from research in various countries could help control an unknown virus. This system could be an effective tool for global collaboration in evidence-based efforts to fight COVID-19. Confirmed COVID-19 cases have been registered in more than 200 countries, and as of July 28, 2020, over 16 million cases have been reported to the World Health Organization. This study was conducted during the epidemic peak of COVID-19 in Italy. The early identification of individuals with suspected COVID-19 is critical in immediately quarantining such individuals. Although surveys are widely used for identifying COVID-19 cases, outcomes, and associated risks, no validated epidemiological tool exists for surveying SARS-CoV-2 infection in the general population. We evaluated the capability of self-reported symptoms in discriminating COVID-19 to identify individuals who need to undergo instrumental measurements. We defined and validated a method for identifying a cutoff score. Our study is phase II of the EPICOVID19 Italian national survey, which launched in April 2020 and included a convenience sample of 201,121 adults who completed the EPICOVID19 questionnaire. The Phase II questionnaire, which focused r future similar pandemics. We developed a short diagnostic scale to detect subjects with symptoms that were potentially associated with COVID-19 from a wide population. Our results support the potential of self-reported symptoms in identifying individuals who require immediate clinical evaluations. Although these results come from the Italian pandemic period, this short diagnostic scale could be optimized and tested as a screening tool for future similar pandemics. COVID-19 has spread like wildfire across the globe, prompting many governments to impose unprecedented stay-at-home orders to limit its transmission. During an extended stay-at-home period, individuals may engage in more online leisure activities. Internet use is a double-edged sword that may have both desirable and undesirable effects on psychological well-being, and this study sought to disentangle adaptive from maladaptive internet use amidst this unusual health crisis. The objectives of this study were to assess the prevalence of probable depression during the COVID-19 stay-at-home period and to test three hypothesized risk reduction or risk elevation mechanisms, namely social capital-accrual, escape-from-self, and time-displacement effects. This study took place from March to May 2020 at the early stage of the pandemic. The study adopted a prospective design, with an online survey administered to 573 UK and 474 US adult residents at two assessment points 2 months apart. The prevalence of moderate to severe depression was 36% (bootstrap bias-corrected and accelerated [BCa] 95% CI 33%-39%) at Time 1 (ie, initial time point) and 27% (bootstrap BCa 95% CI 25%-30%) at Time 2 (ie, follow-up time point).

To characterize the clinical features of idiopathic intracranial hypertension (IIH) in patients >50 years of age compared to the typical IIH population and existing data for this older cohort. Retrospective, clinical cohort study. Medical records of 65 patients >50 years of age at first diagnosis of IIH were reviewed based on the Modified Dandy Criteria from 4 academic centers. Each center provided randomly selected controls from IIH patients <50 years of age for each study patient at their location. Data recorded included patient demographics, presenting symptoms, medications, coexisting medical conditions, cerebrospinal fluid (CSF) opening pressure, treatments, and neuro-ophthalmic data from initial and final visits. Compared to controls, the older cohort showed the following characteristics fewer females (n= 51 [78.5%] vs. controls n= 60 [92.3%]; P= .045), fewer headaches (n= 33 [50.8%] vs. controls 52 [80.0%]; P= .001), more frequent incidental discoveries of papilledema (n= 19 [29.2%] vs. controls 7 [10.8%]; P= .015), and lower CSF opening pressure [median 33cm H O [range 21-58cm H O] vs. the median for controls 34cm H O [range 24-67cm H O; P= .029). Patients with IIH diagnosed at >50 years of age were less often female and had lower CSF opening pressure, fewer headaches, a higher chance of incidentally identified papilledema, and body mass index similar to that of younger IIH patients. Older IIH onset was not associated with worse visual outcome. 50 years of age were less often female and had lower CSF opening pressure, fewer headaches, a higher chance of incidentally identified papilledema, and body mass index similar to that of younger IIH patients. Older IIH onset was not associated with worse visual outcome. To compare the double-Maddox rod test with other methods of measuring cyclodeviation DESIGN Retrospective cohort study. We retrospectively identified 153 adults in a clinical practice with cyclodeviation assessed using double-Maddox rods, of whom 105 were also assessed using fusible synoptophore targets, 73 using nonfusible synoptophore targets, 118 using single-Maddox rod, and 43 using fundus photography. Relationships between double-Maddox rod and other tests were evaluated by calculating mean differences with 95% confidence intervals (CI), intraclass correlation coefficients (ICC), and Bland-Altman plots with linear regression. Synoptophore cross-in-circle targets and the largest (of right or left) single-Maddox rod values were similar to double-Maddox values (mean differences-1.2° and 0.1°, respectively; ICC 0.79 and 0.82, respectively). Synoptophore house targets measured less excyclodeviation (mean difference-2.7°; ICC 0.71). Mean summed single-Maddox rod values were somewhat similar to double-Madrue cyclodeviation and relationships with symptoms. Peritoneal recurrence of gastric cancer after curative surgical resection is common and portends a poor prognosis. Early studies suggest that extensive intraoperative peritoneal lavage (EIPL) might reduce the risk of peritoneal recurrence and improve survival. We aimed to evaluate the survival benefit of EIPL in patients with gastric cancer undergoing curative gastrectomy. In this open-label, phase 3, multicentre randomised trial, patients aged 21-80 years with cT3 or cT4 gastric cancer undergoing curative resection were enrolled at 22 centres from South Korea, China, Japan, Malaysia, Hong Kong, and Singapore. Patients were randomly assigned to receive surgery and EIPL (EIPL group) or surgery alone (standard surgery group) via a web-based programme in random permuted blocks in varying block sizes of four and six, assuming equal allocation between treatment groups. Randomisation was stratified according to study site and the sequence was generated using a computer program and concealed until the interventi [95% CI 0·78-1·52; p=0·62). 3-year overall survival was 77·0% (95% CI 71·4-81·6) for the EIPL group and 76·7% (71·0-81·5) for the standard surgery group. 60 adverse events were reported in the EIPL group and 41 were reported in the standard surgery group. https://www.selleckchem.com/Bcl-2.html The most common adverse events included anastomotic leak (ten [3%] of 346 patients in the EIPL group vs six [2%] of 362 patients in the standard surgery group), bleeding (six [2%] vs six [2%]), intra-abdominal abscess (four [1%] vs five [1%]), superficial wound infection (seven [2%] vs one [<1%]), and abnormal liver function (six [2%] vs one [<1%]). Ten of the reported adverse events (eight in the EIPL group and two in the standard surgery group) resulted in death. EIPL and surgery did not have a survival benefit compared with surgery alone and is not recommended for patients undergoing curative gastrectomy for gastric cancer.

One is that of transforming our links with nature and, particularly, wildlife given the likely COVID-19 origin from illegal wildlife trading. Similar to vector borne diseases (VBD, diseases transmitted by vectors), the COVID-19 pandemic follows related patterns (e.g. no effective or available vaccines, difficult to diagnose, highly localized infection geographical foci, non-human reservoirs) for which we urgently need preventive measures. Towards this aim, governments worldwide must strive to prevent further devastation of natural environments that serve as buffer areas to humans against zoonotic agents (among other health risks), protecting biodiversity and its concomitant causes (e.g. global change), and banning use of wildlife of illegal origin. We herein state that some VBD prevention strategies could also be applied to zoonotic disease prevention, including COVID-19 or any type likely to be related to environmental conditions. The occurrence of future pandemic occurrence will depend on whether governments embrace these aims now.Increasing evidence exisits for the role that shellfish play in the epidemiology of Toxoplasma gondii in marine environment. However, limited information is available on the level of T. gondii infection in wild marine snails, which can play a role in the transmission of T. gondii to other marine organisms and humans. In this study, the prevalence of T. gondii DNA in wild marine snails collected from three coastal cities in China was determined. Between January 2018 and November 2019, 1,206 wild marine snails were randomly collected and examined for the presence of T. gondii DNA using a nested polymerase chain reaction (PCR) targeting T. gondii B1 gene. The amplified products were genotyped using multilocus PCR-restriction fragment length polymorphism analysis. We also examined whether species of snail, sampling region, sampling season, surface runoff near samplic site, residential water discharge near samplic site, and proximity to livestock farms are associated with the occurrence of T. gondii DNA in marine snails.

These approaches can be easily combined with lignin micro-/nanoparticles (LMNP) production. The processes should also be cost-efficient compared to traditional lignin modifications. Biorefinery processes allow much greater flexibility in optimizing the lignin characteristics desirable for specific applications than traditional pulping processes. Such lignin engineering, at the same time, requires an efficient strategy capable of handling large datasets to find correlations between process variables, lignin structures and properties and finally their performance in different applications.Ion exchange chromatography is a powerful and ubiquitous unit operation in the purification of therapeutic proteins. However, the performance of an ion-exchange process depends on a complex interrelationship between several parameters, such as protein properties, mobile phase conditions, and chromatographic resin characteristics. Consequently, batch variations of ion exchange resins play a significant role in the robustness of these downstream processing steps. Ligand density is known to be one of the main lot-to-lot variations, affecting protein adsorption and separation performance. The use of a model-based approach can be an effective tool for comprehending the impact of parameter variations (e.g., ligand density) and their influence on the process. The objective of this work was to apply mechanistic modeling to gain a deeper understanding of the influence of ligand density variations in anion exchange chromatography. To achieve this, 13 prototype resins having the same support as the strong anion exchange resin Fractogel® EMD TMAE (M), but differing in ligand density, were analyzed. Linear salt gradient elution experiments were performed to observe the elution behavior of a monoclonal antibody and bovine serum albumin. A proposed isotherm model for ion exchange chromatography, describing the dependence of ligand density variations on protein retention, was successfully applied. The novel morpholino antisense oligonucleotide viltolarsen targets exon 53 of the dystrophin gene, and could be an effective treatment for patients with Duchenne muscular dystrophy (DMD). We investigated viltolarsen's ability to induce dystrophin expression and examined its safety in DMD patients. In this open-label, multicenter, parallel-group, phase 1/2, exploratory study, 16 ambulant and nonambulant males aged 5-12years with DMD received viltolarsen 40 or 80mg/kg/week via intravenous infusion for 24weeks. Primary endpoints were dystrophin expression and exon 53 skipping levels. In western blot analysis, mean changes in dystrophin expression (% normal) from baseline to Weeks 12 and 24 were-1.21 (P=0.5136) and 1.46 (P=0.1636), respectively, in the 40mg/kg group, and 0.76 (P=0.2367) and 4.81 (P=0.0536), respectively, in the 80mg/kg group. The increase in mean dystrophin level at Weeks 12 and 24 was significant in the 80mg/kg group (2.78%; P=0.0364). Patients receiving 80mg/kg showed a higher mean exon 53 skipping level (42.4%) than those receiving 40mg/kg (21.8%). All adverse events were judged to be mild or moderate in intensity and none led to study discontinuation. Treatment with viltolarsen 40 or 80mg/kg elicited an increasing trend in dystrophin expression and exon 53 skipping levels, and was safe and well tolerated. The decline in motor function appeared less marked in patients with higher dystrophin levels; this may warrant further investigation. This study supports the potential clinical benefit of viltolarsen. Treatment with viltolarsen 40 or 80 mg/kg elicited an increasing trend in dystrophin expression and exon 53 skipping levels, and was safe and well tolerated. The decline in motor function appeared less marked in patients with higher dystrophin levels; this may warrant further investigation. This study supports the potential clinical benefit of viltolarsen. To investigate a planning technique that can possibly reduce low-to-intermediate dose spillage (measured by R50%, D2cm values) in lung SBRT plans. Dose falloff outside the target was studied retrospectively in 102 SBRT VMAT plans of lung tumor. Plans having R50% and/or D2cm higher than recommended tolerances in RTOG protocols 0813 and 0915 were replanned with new optimization constraints using novel shell structures and novel constraints. Violations in the RTOG R50% value can be rectified with a dose constraint to a novel shell structure ("OptiForR50"). The construction of structure OptiForR50% and the novel optimization criteria translate the RTOG goals for R50% into direct inputs for the optimizer. Violations in the D2cm can be rectified using constraints on a 0.5cm thick shell structure with inner surface 2cm from the PTV surface. Wilcoxon signed-rank test was used to compare differences in dose conformity, volume of hot spots, R50%, D2cm of the target in addition to the OAR doses. A two-sided P-value SBRT plans. https://www.selleckchem.com/TGF-beta.html All plans were successfully brought into the zone of no RTOG violations. The hallmark of myelodysplastic syndrome (MDS) remains dysplasia in the bone marrow (BM). However, diagnosing MDS may be challenging and subject to inter-observer variability. Thus, there is an unmet need for novel objective, standardized and reproducible methods for evaluating dysplasia. Imaging flow cytometry (IFC) offers combined analyses of phenotypic and image-based morphometric parameters, for example, cell size and nuclearity. Hence, we hypothesized IFC to be a useful tool in MDS diagnostics. Using a different-from-normal approach, we investigated dyserythropoiesis by quantifying morphometric features in a median of 5953 erythroblasts (range 489-68,503) from 14 MDS patients, 11 healthy donors, 6 non-MDS controls with increased erythropoiesis, and 6 patients with cytopenia. First, we morphometrically confirmed normal erythroid maturation, as immunophenotypically defined erythroid precursors could be sequenced by significantly decreasing cell-, nuclear- and cytoplasm area. In MDS samples, we demons We propose that IFC holds great promise as a powerful and objective tool in the complex setting of MDS diagnostics with the potential for minimizing inter-observer variability.

The aims of the study were to compare characteristics, resources, benefits and outcomes of academic-clinical collaborations of nursing researcher leaders from academic, clinical and joint-employer sites. Few research-based publications addressed academic-clinical research collaborations. https://www.selleckchem.com/products/crenolanib-cp-868596.html New knowledge could increase nursing and multidisciplinary research productivity, including implementation science. An anonymous survey using a 40-item questionnaire. Information letters with a link to the questionnaire were emailed to United States nursing research leaders. Data were grouped by institution type academic, clinical or joint-employer. Analyses included Kruskal-Wallis tests for ordered responses, Pearson's chi-square test or Fisher's exact test for categorical responses and Cohen's Kappa agreement statistic for expected and actual time devoted to research. STROBE guidelines were followed. Of 120 respondents from academic (n=60; 50.0%), clinical (n=53; 41.2%) and joint-employer (n=7; 5.8%) sites, 78.3%,laboration to address important clinical questions aimed at improving clinical outcomes. Despite some successful outcomes, potential benefits of academic-clinical research collaborations have not been fully actualised. Despite some successful outcomes, potential benefits of academic-clinical research collaborations have not been fully actualised. Dependence-like behaviour may complicate withdrawal and increase risk of relapse of medication overuse headache (MOH). The most effective treatment for reducing dependence-like behaviour is unknown. To compare patient-reported outcomes among three treatment strategies for MOH. The primary outcome was change in Severity of Dependence Scale (SDS) score from baseline to 6months. Patients with MOH were randomized to (1) withdrawal combined with preventive medication from start (W+P), (2) preventive medication without withdrawal (P), or (3) withdrawal with optional preventive medication 2months after withdrawal (W). At baseline, 2, and 6months, patients filled out SDS (used for measurements of dependence-like behaviour and treatment feasibility), Headache Under-Response of Treatment (HURT) and WHO Quality of Life BREF questionnaires. Out of 120 patients with MOH, 100 completed the 6-month follow-up and filled out questionnaires. The W+P arm was the most effective in treating MOH. After 6months, the SDS scogy that reduces dependence-like behaviour the most in MOH patients. Patients initially considered preventive treatment without withdrawal as the most feasible treatment. However, no difference in feasibility between the three arms was found at 6-month follow-up. Withdrawal combined with preventive medication is recommended for treatment of MOH.We present the synthesis and coordination chemistry of a bulky, tripodal N,N,O ligand, ImPh2 NNOtBu (L), designed to model the 2-His-1-carboxylate facial triad (2H1C) by means of two imidazole groups and an anionic 2,4-di-tert-butyl-subtituted phenolate. Reacting K-L with MCl2 (M = Fe, Zn) affords the isostructural, tetrahedral non-heme complexes [Fe(L)(Cl)] (1) and [Zn(L)(Cl)] (2) in high yield. The tridentate N,N,O ligand coordination observed in their X-ray crystal structures remains intact and well-defined in MeCN and CH2 Cl2 solution. Reacting 2 with NaSPh affords a tetrahedral zinc thiolate complex, [Zn(L)(SPh)] (4), that is relevant to isopenicillin N synthase (IPNS) biomimicry. Cyclic voltammetry studies demonstrate the ligand's redox non-innocence, where phenolate oxidation is the first electrochemical response observed in K-L, 2 and 4. However, the first electrochemical oxidation in 1 is iron-centred, the assignment of which is supported by DFT calculations. Overall, ImPh2 NNOtBu provides access to well-defined mononuclear, monoligated, N,N,O-bound metal complexes, enabling more accurate structural modelling of the 2H1C to be achieved.Irreversible denervation atrophy remains an unsolved clinical problem, and the role of skeletal muscle stem cell (MuSC, satellite cell) depletion in this process is unclear. We investigated the ability of MuSCs to regenerate muscle in the context of denervation. Three to 12 months following sciatic denervation in mice, MuSC number, size, EdU uptake, rate of division, and mitochondrial activity were increased. Following acute myotoxin injury, denervated muscles formed new muscle fibers in situ. MuSCs isolated via flow cytometry from denervated mouse muscle, or from atrophic denervated gluteus maximus muscles of humans with complete spinal cord injuries two decades prior, formed new muscle fibers and reoccupied the anatomic niche after transplantation into uninjured muscle. Our results show unequivocally that, even after prolonged denervation, MuSCs retain intrinsic regenerative potential similar to that of uninjured MuSCs. Treatment of denervation atrophy will require elucidating the non-MuSC environmental changes in muscle that prevent functional regeneration.To reconstruct the phenotypical and clinical implications of the Italian genetic structure, we thoroughly analyzed a whole-exome sequencing data set comprised of 1686 healthy Italian individuals. We found six previously unreported variants with remarkable frequency differences between Northern and Southern Italy in the HERC2, OR52R1, ADH1B, and THBS4 genes. We reported 36 clinically relevant variants (submitted as pathogenic, risk factors, or drug response in ClinVar) with significant frequency differences between Italy and Europe. We then explored putatively pathogenic variants in the Italian exome. On average, our Italian individuals carried 16.6 protein-truncating variants (PTVs), with 2.5% of the population having a PTV in one of the 59 American College of Medical Genetics (ACMG) actionable genes. Lastly, we looked for PTVs that are likely to cause Mendelian diseases. We found four heterozygous PTVs in haploinsufficient genes (KAT6A, PTCH1, and STXBP1) and three homozygous PTVs in genes causing recessive diseases (DPYD, FLG, and PYGM). Comparing frequencies from our data set to other public databases, like gnomAD, we showed the importance of population-specific databases for a more accurate assessment of variant pathogenicity. For this reason, we made aggregated frequencies from our data set publicly available as a tool for both clinicians and researchers (http//nigdb.cineca.it; NIG-ExIT).
