Aims: Lesbian, gay, bisexual, transgender and other people (LGBT+) individuals may have a greater risk of experiencing mental and physical health issues. In the past years, the predominant theme of research was HIV/AIDS and sexually transmitted infections (STIs). This study aimed to explore the most recent patterns in medical research concerning LGBT+ persons. Methods: A bibliometric analysis using Biblioshiny was conducted. Based on previous studies, years of observation ranged between 2008 and 2021. Web of Science Core Collection was used. Results: A total of 31,039 articles were selected. Top journals centered around HIV/AIDS and STIs (n = 6), followed by sexual behaviors/sexuality (n = 2) and LGBT+ health (n = 2). The US led in research output (n = 16,249). Papers were categorized into three main clusters (which showed different evolution across time): one addressing HIV/AIDS, STIs, and sexual behaviors, another focusing on mental health, discrimination, and stigma, and a third, smaller cluster examining transgender, intersex, and gender-diverse health. Conclusions: This article highlighted a growth in LGBT+ health research, uncovering research disparities among countries. While HIV/AIDS and STIs still dominated, a crucial theme concerning mental health, discrimination, and stigma has been rising. Declining interest in gender-diverse health, and disparities in research attention to different LGBT+ subgroups, underscored the need for more comprehensive and inclusive research to address complex health disparities.

Participatory budgeting was introduced in Latin America in 1989, and within 10 years, this innovation spread all over the world. At the same time, researchers outside Latin America showed a growing interest in the issue, resulting in more diversified research. A few scholars have already tried to provide comprehensive literature reviews; however, these efforts have had a narrow focus or have appeared as embedded parts of analyses of specific issues. This article aims to (1) identify recent worldwide research trends in participatory budgeting, (2) identify the most popular issues addressed by international research and (3) suggest avenues and subfields of further research. We employed bibliometric techniques to analyse articles published in journals that were indexed and abstracted in the Web of Science database from 2001 to 2020.

Abstract: Background: Rheumatoid arthritis (RA) is a chronic autoimmune disease affecting the joints. A number of novel treatment modalities have been introduced over the past years, and rheumatologists are now attempting to institute optimal treatment in recent-onset arthritis. To facilitate diagnosis during the early stages of disease, when often not all clinical symptoms are manifest, a good serological marker is needed. Methods: Antibodies directed to citrullinated proteins provide this ability. The most sensitive assay for detecting these antibodies is the so-called anti-cyclic citrullinated peptide, second generation (CCP II) enzyme-linked immunosorbent assay (ELISA). Results: The diagnostic and prognostic potential of anti-CCP antibodies and the availability of a fully automated assay method lead us to conclude that the test is satisfactory for routine use as a serological marker of RA. In addition, we consider the potential of multiplex autoantibody assays, including miniaturized, high-throughput microarray technology, to improve diagnosis and prognostication in early onset arthritis patients.

Background: Hemolyzed specimens are a relatively frequent occurrence in laboratory practice, accounting for nearly 60% of rejected specimens. Some formulas have been proposed as a means of making a quantitative correction of the effect of hemolysis. We assessed the accuracy of serum potassium determinations in hemolyzed samples, including the mean corpuscular hemoglobin concentration (MCHC) of each subject in the correction formula (rbcK+= [iK+ /MCHC]fsHb). Methods: The potassium values post-induction of hemolysis (hK+) were correlated with the potassium values obtained by combining/totaling the serum potassium (sK+) with the potassium released by the red cells after rupture (rbcK+), calculated with the above formula. Results: No statistically significant difference was found between the mean concentrations of hK+ and the potassium calculated with the above formula (calcK+); there was no significant deviation from linearity. Conclusions: The formula we propose produces more accurate measurements of potassium because it uses the MCHC value of each patient in the calculation, which may prevent the need for repeated serum collection and assays.

Our study evaluated the possible interference of Burosumab (human recombinant monoclonal antibody directed against N-terminal domain of FGF23) on the immunoassay of intact FGF23 (iFGF23) with the Liaison XL. The analytical method uses three different antibodies, one of which directed against the N-terminal portion of FGF23. The evaluation of the method accuracy involved the fully automated execution of a dilution test on EDTA plasma from 5 subjects who had not received any monoclonal antibody (mAb), 20 EDTA plasma from patients treated with Burosumab, and 2 EDTA plasma from subjects who had not received any mAb in witch an adequate volume of Burosumab had been added in vitro. One sample with specific diluent (LIAISON® FGF 23) with an adequate volume of Burosumab had been added in vitro. The dilution assay provided highly inaccurate iFGF23 results in samples with therapeutic concentrations of Burosumab and in samples with concentrations below the LoQ (6.5 pg/mL). The addition of Burosumab to the diluent did not produce any analytical interference. Dissociation of iFGF23 from the mAb-target complex in diluted sample could explain the loss of accuracy in the iFGF23 immunoassay using the Liaison XL analyzer. Burosumab could be an interferent in immunoassay procedures of iFGF23.

Thiabridged [5]helicenes are obtained from thioaryl- N -phthalimido benzo[ a ]phenothiazines using a hydrogen bond donor/Lewis base organocatalytic approach. Resolution of [5]helicenes using either (1 S )-(-)-camphanic acid as a chiral auxiliary or CSP-HPLC is reported. Thiabridged [5]helicenes show an exceptional configurational stability with racemization energy barriers higher than 40 kcal mol -1 . Electronic circular dichroism and TD-DFT calculations permit the assignment of the absolute configuration, demonstrating that the sign of optical rotation is not easily related to the M or P structure. Separated enantiomers show circularly polarized luminescence with high dissymmetry ratio.

The aim of this study was to evaluate changes in the concentration of N-terminal type I collagen extension pro-peptide (PINP), tartrate-resistant acid phosphatase (TRAcP), and parathyroid hormone-related protein (PTHrP) in saliva during orthodontic treatment in order to evaluate whether changes in bone turnover marker (BTM) concentration can help highlight the effects of orthodontic mechanical loading in the absence of clinical evidence of tooth movement in terms of tooth movement. Saliva samples from 25 apparently healthy young subjects (10 females and 15 males) were collected using Salivette ® (Sarstedt) with cotton swabs and the concentrations of PTHrP, TRAcP 5b, and PINP were analyzed at time 0 (T1), 25 days (T2), and at 45 days (T3). Differences in the median value of biomarker levels between baseline T1 and follow-up of the different groups (T2 and T3) were assessed using the non-parametric Mann-Whitney U test. Trough concentrations of P1NP, PTHrP, and TRAcP were 0.80 µg/L, 0.21 ng/mL, and 0.90 U/L above the method LOD. The non-parametric Mann-Whitney U test confirmed a statistically significant difference in T1 versus concentrations of T2 and T3. All subjects evaluated had a statistically significant difference between T1 vs. T3. when compared with the specific critical difference (RCV) for the analyte The results obtained demonstrate that the evaluation of BTM changes in saliva can help the evaluation of orthodontic procedures and the monitoring of biomechanical therapy.

The purpose of the present study was to evaluate the concentrations of some bone turnover markers in preterm neonates with uncomplicated clinical course in the first month of life. Samples from 13 preterm neonates were collected at three different times: at birth (T0) from umbilical cord blood (UCB); and at 15 (T1) and 30 (T2) days of life from peripheral blood (PB). The concentrations of calcium (Ca), phosphate (P), total alkaline phosphatase (ALP), Collagen Type 1 Amino-terminal Propeptide (PINP), osteocalcin (OC), Collagen Type 1 Carboxyl-Terminal Telopeptide (CTX) and Leptin were assessed. A statistically significant difference for ALP concentration at birth versus T1 and T2 was found. An evident increase in the median concentrations of CTX, OC and PINP from T0 to T2 were observed. A significant difference was also found for Leptin concentration at T0 compared to T1. In preterm infants, in the absence of acute or chronic medical conditions and without risk factors for metabolic bone disease (MBD) of prematurity, there is a significant increase in bone turnover markers during the first month of life. The knowledge of the variations in these markers in the first weeks of life, integrated by the variations in the biochemical indicators of bone metabolism, could help in recognizing any conditions at risk of developing bone diseases.

Background: Candida auris (CA) is an emerging fungus, classified as an urgent global health threat, that resists common antifungal drugs and decontamination procedures; identification requires specific tools; transmissibility and mortality are high in healthcare settings. Infection and colonisation can be long-lasting, leading to problems in isolation procedures and the risk of outbreaks. This study aims to evaluate publication and citation related metrics, identify major keywords and topics, and assess geographic distribution of published articles., Methods: A list of all publications containing "Candida auris" in all fields was extracted from Web Of Science on date 2023/01/02. Bibliometric analysis was conducted using the bibliometrix and biblioshiny packages on RStudio., Results: Total publications (TP) were 1283 with an annual growth rate of 53.91%. Total citations were 27854, with an average of 21.71 citations per paper. The core sources are 9 out of 322, according to Bradford's law. In only 42 countries where CA was identified, articles on the topic were published (89%). The origin of TP is concentrated in high-income countries (68.22%). Trending topics about CA include epidemiology, identification and resistance., Conclusion: Our analysis shows a growing interest in scientific literature on the topic of CA, led by Europe. In some countries where CA has been identified, no papers have been published. Despite the multidrug-resistance of CA, the topic of therapy is not much debated. Our findings highlight the need to increase focus on CA in order to promote health systems' preparedness and to properly address the spread of this worrisome pathogen., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 The Author(s).

Purpose: to investigate the effects of intensive chemotherapy and glucocorticoid (GC) treatment on bone remodeling markers in children with acute lymphoblastic leukemia (ALL)., Methods: A cross-sectional study was carried out in 39 ALL children (aged 7.64 ± 4.47) and 49 controls (aged 8.7 ± 4.7 years). Osteoprotegerin (OPG), receptor activator of NF-κB ligand (RANKL), osteocalcin (OC), C-terminal telopeptide of type I collagen (CTX), bone alkaline phosphatase (bALP), tartrate-resistant acid phosphatase 5b (TRACP5b), procollagen type I N-terminal propeptide (P1NP), Dickkopf-1 (DKK-1), and sclerostin were assessed. Statistical analysis was conducted using the principal component analysis (PCA) to study patterns of associations in bone markers., Results: ALL patients showed significantly higher OPG, RANKL, OC, CTX, and TRACP5b than the controls ( p ≤ 0.02). Considering ALL group, we found a strong positive correlation among OC, TRACP5b, P1NP, CTX, and PTH (r = 0.43-0.69; p < 0.001); between CTX and P1NP (r = 0.5; p = 0.001); and between P1NP and TRAcP (r = 0.63; p < 0.001). The PCA revealed OC, CTX, and P1NP as the main markers explaining the variability of the ALL cohort., Conclusions: Children with ALL showed a signature of bone resorption. The assessment of bone biomarkers could help identify ALL individuals who are most at risk of developing bone damage and who need preventive interventions.

Aim of the Study: We evaluated and compared blood gas analysis (EGA) non-conformities (NC) considered operator-dependent performed in Point-Of-Care (POC) analyzer as quality indicators (IQ) of the pre-analytical phase. To this end, four different NC registered in the resuscitation departments of the Hospital Polyclinic Bari from the beginning of the pandemic (March 2020) until February 2022 were evaluated. The results obtained were compared with those recorded in the pre-COVID period (March 2018-February 2020) to check if there were differences in number and type., Material and Methods: GEM 4000 series blood gas analyzers (Instrumentation Laboratory, Bedford, MA, United States) are installed with integrated Intelligent Quality Management (iQM ® ), which automatically identify and log pre-analytical errors. All blood gas analyzers are connected to the company intranet and interfaced with the GEM Web Plus (Werfen Instrumentation Laboratory, Bedford, MA, United States) data management information system, which allows the core laboratory to remotely supervise all decentralized POC stations. The operator-dependent process NC were expressed in terms of absolute and relative proportions (percentiles and percentage changes). For performance evaluation, the Mann-Whitney U test, Chi-squared test and Six-Sigma Metric calculation for performance classification were performed., Results: In the COVID period, 31,364 blood gas tests were performed vs. 16,632 tests in the pre-COVID period. The NC related to the suitability of the EGA sample and manageable by the operators were totals of 652 (3.9%) and 749 (2.4%), respectively, in the pre-COVID and COVID periods. The pre-analytical phase IQs used did not show statistically significant differences in the two periods evaluated. The Sigma evaluation did not show an increase in error rates., Conclusions: Considering the increase in the number of EGAs performed in the two periods, the training procedures performed by the core laboratory staff were effective; the clinical users of the POC complied with the indications and procedures shared with the core laboratory without increasing the operator-dependent NCs. Furthermore, the core laboratory developed monitoring activities capable of guaranteeing the maintenance of the pre-analytical quality.

Objectives: The aim of this study was to relate IL-6 and IL-1β serum levels with the severity of olfactory disorders and with the type of unperceived odors., Methods: 82 inpatients (45 men aged 62.3 ± 14.2 and 37 women aged 57.1 ± 12.8) with only smell dysfunctions were divided into two groups. The evaluation of the smell disorder was carried out with a questionnaire to define which sensitivity is most compromised in COVID-19 patients. Cytokine levels were measured with chemiluminescence and ELISA assay. Statistical analyses were performed with the Wilcoxon Rank test, Welch's T-test, and Mann-Whitney test (p < 0.05)., Results: Statistically significant differences in IL-6 and IL-1 β levels were found in moderate disease patients when there was an impairment of trigeminal sensitivity (p <0.05) and trigeminal and olfactory sensitivity., Conclusions: The results obtained showed that in COVID-19 patients the impairment of trigeminal sensitivity in association with olfactory sensitivity was more prevalent in moderate than in mild forms., (Copyright© Bentham Science Publishers; For any queries, please email at epub@benthamscience.net.)

Background: The measurement of Fibroblast growth factor 23 (FGF23) may be useful in the diagnosis and management of abnormal phosphate metabolism in both patients with preserved renal function or with chronic kidney disease (CKD). FGF-23 tests differ considerably by molecule assayed (iFGF23 or cFGF23), analytical performance and reference ranges. We establish iFGF23 Upper Reference Limits (URL) in apparently healthy pediatric individuals using automated immunochemiluminescent assay., Methods: We measured the levels of plasma iFGF23 from 115 samples from apparently healthy pediatric subjects [59 (51.3%) individuals were male; median age 10 years (range 1-18)] included in an observational study conducted at Policlinico University Hospital of Bari. The method used for the iFGF23 assay was immunochemiluminescent sandwich assay developed by DiaSorin on the Liaison XL platform. Statistical calculation of 95% reference interval, right-sided (CLSI C28-A3) and verification of age and sex covariables was performed for the calculation of the URL., Results: The URL concentration of iFGF23 was 61.21 pg/mL (58.63 to 63.71, 90% CI). No significant differences were found between the median concentrations of iFGF23 differentiated by sex and age., Conclusions: The dosage of iFGF23 is important both for the differential diagnosis of the various forms of rickets, and for the subsequent monitoring of the effectiveness of drug treatment. We have established the URL for the iFGF23 Liaison test in apparently healthy pediatric subjects. The availability of iFGF23 pediatric reference values will allow a better clinical use of the test., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Brescia, Fontana, Lovero, Capobianco, Marsico, De Chirico, Pinto, Varraso, Cazzolla and Di Serio.)

In the United States, from 1999 to 2019, opioid overdose, either regularly prescribed or illegally acquired, was the cause of death for nearly 500,000 people. In addition to this pronounced mortality burden that has increased gradually over time, opioid overdose has significant morbidity with severe risks and side effects. As a result, opioid misuse is a cause for concern and is considered an epidemic. This article examines the trends and consequences of the opioid epidemic presented in recent international literature, reflecting on the causes of this phenomenon and the possible strategies to address it. The detailed analysis of 33 international articles highlights numerous impacts in the social, public health, economic, and political spheres. The prescription opioid epidemic is an almost exclusively North American problem. This phenomenon should be carefully evaluated from a healthcare systems perspective, for consequential risks and harms of aggressive opioid prescription practices for pain management. Appropriate policies are required to manage opioid use and prevent abuse efficiently. Examples of proper policies vary, such as the use of validated questionnaires for the early identification of patients at risk of addiction, the effective use of regional and national prescription monitoring programs, and the proper dissemination and translation of knowledge to highlight the risks of prescription opioid abuse.

Upper-respiratory-tract infections (URTIs) are among the main causes of antibiotic prescriptions in pediatric patients. Over one-third of all antibiotic prescriptions for URTIs in children are estimated to be inappropriate, as the majority of URTIs are caused by viral agents. Several strategies, including clinical scoring algorithms and different point-of-care tests (POCTs) have been developed to help discriminate bacterial from viral URTIs in the outpatient clinical setting. A systematic review of the literature was conducted following PRISMA guidelines with the objective of summarizing evidence from health-economic evaluations on the use of POCT for URTIs in pediatric outpatients. A total of 3375 records identified from four databases and other sources were screened, of which 8 met the inclusion criteria. Four studies were classified as being of high reporting quality, and three were of medium quality. Five out of eight studies concluded in favor of strategies that included POCTs, with an additional study finding several POCTs to be cost-effective compared to usual care but over an acceptable WTP threshold. This review found POCT could be a valuable tool for antimicrobial stewardship strategies targeted towards childhood URTIs in primary care.

Medical tourism is an expanding phenomenon. Scientific studies address the changes and challenges of the present and future trend. However, no research considers the study of bibliometric variables and area of business, management and accounting. This bibliometric analysis discovered the following elements: (1) The main articles are based on guest services, management, leadership principles applied, hotel services associated with healthcare, marketing variables and elements that guide the choice in medical tourism; (2) The main authors do not deal with tourism but are involved in various ways in the national health system of the countries of origin or in WHO; (3)cost-efficiency and analytical accounting linked to medical tourism structures and destination choices are not yet developed topics.

The phosphorylated neurofilament heavy chain (pNfH) is a promising biomarker in amyotrophic lateral sclerosis (ALS). We examined plasma pNfH concentrations in order to corroborate its role as a diagnostic and prognostic biomarker in ALS. Incident ALS cases enrolled in a population-based registry were retrospectively selected and matched by sex and age with a cohort of healthy volunteers. Plasma pNfH levels were measured by an ELISA kit and correlated with clinical parameters. Discrimination ability of pNfH was tested using receiving operating characteristic (ROC) curves. Kaplan-Meier (KM) analysis and Cox proportional hazard models were used for survival analysis. Plasma pNfH was significantly higher in patients compared to controls. An optimal cut-off of 39.74 pg/ml discriminated cases from controls with an elevated sensitivity and specificity. Bulbar-onset cases had higher plasma pNfH compared to spinal onset (p = 0.0033). Furthermore, plasma pNfH positively correlated with disease progression rate (r = 0.19, p = 0.031). Baseline plasma pNfH did not influence survival in our cohort. Our findings confirmed the potential utility of plasma pNfH as a diagnostic biomarker in ALS. However, further studies with longitudinal data are needed to corroborate its prognostic value., (© 2022 The Authors.

Parathyroid hormone-related peptide (PTHrP) is expressed at a wide range of sites in the body and performs different functions including vasodilation, relaxation of smooth muscle cells, and regulation of bone development. PTHrP also mediates hypercalcemia related to neoplastic diseases. However, reference ranges specific method and age were not evaluated. We establish PTHrP reference ranges in apparently healthy, normocalcemic, normophosphatemic pediatric individuals. In this observational prospective, study we measured PTHrP in serum from 178 samples (55.06% male 44.94% female) from apparently healthy pediatric subjects [median age 10 years (range 1-18)] subunit ELISA method The statistical analysis performed provided for the calculation of the 95% reference interval, right-sided, with a non-parametric percentile method (CLSI C28-A3). Upper reference limits (URL) for PTHrP was 2.89 ng/mL (2.60 to 3.18; 90% CI). No significant differences were found between the median PTHrP concentrations in males vs females and in the age range categories selected. Comprehensive normal values for PTHrP are indispensable to the assessment of calcium phosphorus dysfunction in children. Severe hypercalcemia is a rare, but clinically significant condition, in infancy and childhood. PTHrP values higher than the reference value may help to distinguish the hypercalcemic product of a malignancy, paraneoplastic syndromes mediated by PTHrP, from other causes.

Background: Delirium is frequent though undetected in older patients admitted to the Emergency Department (ED)., Aims: To develop and validate a delirium risk assessment tool for older persons admitted to the ED Observation Unit (OU)., Methods: We used data from two samples of 65 + year-old patients, one admitted to the ED of Brescia Hospital (n = 257) and one to the ED of Desio Hospital (n = 107), Italy. Data from Brescia were used as training sample, those collected in Desio as testing one. Delirium was assessed using the 4AT and patients' characteristic were retrieved from medical charts. Variables found to be associated with delirium in the training sample were tested for the creation of a delirium risk assessment tool. The resulting tool's performances were assessed in the testing subsample., Results: Of all possible scores tested, the combination with the highest discriminative ability in the training sample included: age ≥ 75 years, dementia diagnosis, chronic use of neuroleptics, and hearing impairment. The delirium score exhibited an AUC of 0.874 and 0.893 in the training and testing samples, respectively. For a 1-point increase in the score, the odds of delirium increased more than twice in both samples., Discussion: We propose a delirium risk assessing tool that includes variables that can be easily collected at ED admission and that can be calculated rapidly., Conclusion: A risk assessment tool could help improving delirium detection in older persons referring to ED., (© 2021.

Background: Intraoperative Neurophysiological Monitoring (IONM) reduces the incidence of Recurrent Laryngeal Nerve (RLN) injuries during thyroid surgery. To preserve nerve function, long acting neuromuscular blocking agents (NMBA) should be avoided. However, NMBA are necessary for laryngoscopy and endotracheal intubation. We designed this double-blinded, randomized, placebo-controlled trial to assess if a low-dose of rocuronium given at intubation would affect the IONM data recorded before the thyroid dissection., Methods: Hundred patients undergoing elective thyroid surgery were randomized to receive either 0.3 mg kg -1 of low dose rocuronium (intervention) or no-NMBA (control). Intubation was performed with video-laryngoscopy. IONM was placed on RLN and nerve stimulation was performed before and after thyroid dissection. The presence of a valid amplitude prior to dissection was defined when the IONM signal was >100 μV. Occurrence of difficult laryngoscopy was reported together with intubation details including time, difficulty and failure. The lowest peripheral saturation (SpO 2 ) and the number of desaturation episodes during the intubation were also registered., Results: No patients showed impaired IONM signal before dissection in both groups. Cormack-Lehane grade was higher in the intervention group (1 1 ; 2 ) compared to control one (1 1 ; 1 ; P = 0.046). No-NMBA patients had increased number of difficult laryngoscopies (21% versus 6%, P = 0.041) and intubations (34% versus 8%; P = 0.003) as well as a longer time to intubation (78 [55; 175] versus 55 [31; 110] sec; P = 0.006). Lower values of peripheral SpO 2 during intubation attempt were registered in the no NMBA group (99 [97; 100] versus 99 [99; 100] %; P = 0.020). However, the number of intubation failure was similar between groups (p=0.495)., Conclusions: Low-dose of rocuronium does not compromise pre-dissection IONM signal and improves intubation condition when compared to a relaxant free strategy., Competing Interests: Declarations of competing interest Dr. Navalesi's research laboratory has received equipment and grants from Maquet Critical Care, Draeger and Intersurgical S.p.A.

Beta-amyloid (Aβ) plaques have been observed in the brain of healthy elderlies with frequencies strongly influenced by age. The aim of the study is to evaluate the role of age and other biochemical and hematological parameters on Aβ 1-42 plasma levels in cognitively and neurologically normal individuals. Two-hundred and seventy-five normal subjects stratified by age groups (<35 years, 35-65 years, and >65 years) were included in the study. Aβ 1-42 plasma levels significantly correlated with age ( r s = 0.27; p < 0.0001) in the whole sample, inversely correlated with age in the first age group ( r s = -0.25, p = 0.01), positively correlated in the second group ( r s = 0.22, p = 0.03), while there was no significant correlation in the older group ( r s = 0.02, p = 0.86). Both age ( β -estimate = 0.08; p < 0.001) and cholesterol ( β -estimate = 0.03; p = 0.009) were significantly associated with Aβ 1-42 plasma level in multivariable analysis. However, only the association with age survived post hoc adjustment for multiple comparisons. The different effects of age on the Aβ level across age groups should be explored in further studies to better understand the age-dependent variability. This could better define the value of plasma Aβ as a biomarker of the Alzheimer neuropathology., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2021 Zecca, Pasculli, Tortelli, Dell’Abate, Capozzo, Barulli, Barone, Accogli, Arima, Pollice, Brescia and Logroscino.)

Three-dimensional printing technologies allow for the fabrication of complex parts with accurate geometry and less production time. When applied to biomedical applications, two different approaches, known as direct or indirect bioprinting, may be performed. The classical way is to print a support structure, the scaffold, and then culture the cells. Due to the low efficiency of this method, direct bioprinting has been proposed, with or without the use of scaffolds. Scaffolds are the most common technology to culture cells, but bioassembly of cells may be an interesting methodology to mimic the native microenvironment, the extracellular matrix, where the cells interact between themselves. The purpose of this review is to give an updated report about the materials, the bioprinting technologies, and the cells used in cancer research for breast, brain, lung, liver, reproductive, gastric, skin, and bladder associated cancers, to help the development of possible treatments to lower the mortality rates, increasing the effectiveness of guided therapies. This work introduces direct bioprinting to be considered as a key factor above the main tissue engineering technologies.

Background: Knowledge resources are in most productive sectors distinctive in terms of competitiveness. Still, in the health sector, they can have an impact on the health of the population, help make the organisations more efficient and can help improve decision-making processes. The purpose of this paper is to investigate the Intellectual Capital impact on healthcare organization' performance in the Italian healthcare system., Methods: The theoretical framework linked to intellectual Capital in the health sector and the performance evaluation related to efficiency supports the analysis carried out in two stages to determine the right placement of resources and the exogenous variables that influence performance level. The evaluation of the impact of the ICs on performance is determined through the Data envelopment analysis. The incidence of the exogenous variables has been established through linear regression., Results: Empirical results in Italy show some IC components influence organization 'performance (Essential Levels of Assistance) and could be used for defining the policy of allocation of resources in healthcare sector. The efficiency of 16 regions considered in 2016 based on Slack-Based-Model constant returns-to-scale (SBM-CRS) and Slack-Based-Model variable returns-to-scale (SBM-VRS) identifies a different ability to balance IC and performance. Current healthcare expenditure and the number of residents is correlated with the identified efficiency and performance levels., Conclusions: This paper embeds an innovative link between healthcare performance, in term of efficiency and IC which aligns resource management with future strategy. The study provides a new decision-making approach.

The classic cell culture involves the use of support in two dimensions, such as a well plate or a Petri dish, that allows the culture of different types of cells. However, this technique does not mimic the natural microenvironment where the cells are exposed to. To solve that, three-dimensional bioprinting techniques were implemented, which involves the use of biopolymers and/or synthetic materials and cells. Because of a lack of information between data sources, the objective of this review paper is, to sum up, all the available information on the topic of bioprinting and to help researchers with the problematics with 3D bioprinters, such as the 3D-Bioplotter™. The 3D-Bioplotter™ has been used in the pre-clinical field since 2000 and could allow the printing of more than one material at the same time, and therefore to increase the complexity of the 3D structure manufactured. It is also very precise with maximum flexibility and a user-friendly and stable software that allows the optimization of the bioprinting process on the technological point of view. Different applications have resulted from the research on this field, mainly focused on regenerative medicine, but the lack of information and/or the possible misunderstandings between papers makes the reproducibility of the tests difficult. Nowadays, the 3D Bioprinting is evolving into another technology called 4D Bioprinting, which promises to be the next step in the bioprinting field and might promote great applications in the future.

Nanofibrous structures have morphological similarities to extracellular matrix and have been considered as candidate scaffolds in tissue engineering. Scaffolds made from electrospun fibers have potential in cell adhesion, proliferation and cell function. In this study, different percentages of graphene have been dispersed in a polycaprolactone-cyclopentanone solution to produce electrospun fibers. The microstructure and morphology of the fibers and the mechanical behavior of the electrospun systems were evaluated to analyze the influence of graphene content on the performances of the fibers. A significant dimensional difference between the fibers diameters of was obtained due to the graphene percentage. Accordingly, the mechanical properties of the fibrous systems are found to be influenced by the presence of the graphene. Rat stem cells were cultured on the fibrous scaffolds to evaluate the effect of the arrangement of the fibers on the morphology of the cells and differentiation into neurons.

Aim of the Study: Beta-Amyloid 1-42 peptide (βA42) is a cerebro-spinal fluid (CSF) biomarker, key element of the NIA Alzheimer's disease diagnostic criteria. The enzyme-linked immunosorbent assay (ELISA) has been the mainstay method for βA42 measurement on cerebrospinal fluid (CSF). Recently, a new βA42 measurement method in chemiluminescence enzyme immunoassay (CLEIA) is available on Lumipulse G 600 II automatic platform. The aim of the work was to evaluate the concordance of the ELISA and the new method (CLEIA) in the CSF βA42 levels measurement., Materials and Methods: CSF βA42 levels were assayed in 49 samples using the ELISA method (Innotest β- amyloid 1-42, Fujirebio Europe N.V., Gent, Belgium) and CLEIA method on Lumipulse G600II fully automatic platform (Lumipulse G β- amyloid 1-42, Fujirebio Europe N.V., Gent, Belgium). We compared values of the two methods using acceptability interval based on Inherent Combined Imprecision (ICI), the Passing-Bablok regression analysis, the Pearson correlation coefficient (r) and the Bland-Altman plot., Results: The analysis of the ICI showed that the two methods differ substantially. The regression equation (y = -103.04 + 1.52×) highlighted the presence of proportional systematic difference, without significant deviation from linearity (p = .42). The Pearson correlation coefficient was 0.826. The Bland-Altman plot analysis showed a significant systematic difference in the two methods: ELISA measurements were in average -27.06% (95% CI -31.89 to -22.23%) lower compared to CLEIA ones., Conclusions: Our study highlighted a difference between the two methods. Therefore, the cut-off for the normal levels of βA42 should be reviewed in the laboratory report., (Copyright © 2019 Elsevier B.V. All rights reserved.)

Background: In clinical practice, the use of plasma β-Amyloid1-42 (Aβ 1-42 ) as biomarker for Alzheimer's disease is largely limited by the absence of reference values. The aim of this study was to evaluate Aβ 1-42 plasma concentrations in cognitively normal subjects and to propose reference values., Methods: Plasma samples were obtained from 245 subjects, with a wide age-range (19-89 years), enrolled at the Unit of Laboratory Medicine of the "Azienda Ospedaliera Cardinale G. Panico" (younger subjects) and from a population-based study on aging (GreatAGE study) (older subjects). Three different age-groups were established: young (≤ 34), adult (35 ≤ age ≤ 64) and old (>64). The Innogenetics Elisa kit for plasma Aβ 1-42 was used for the analysis., Results: The mean (SD) concentration of plasma Aβ 1-42 was 17.65 (5.71) pg/mL. A positive trend was found in Aβ 1-42 levels across the three age groups (p < .0001): young subjects showed values of Aβ 1-42 significantly lower than the adult group (p < .0001) and than the old one (p < .0001 overall); no significant differences were found between the adult and the old groups (p = 1.0000). For the entire cohort the lower limit of 90% Reference Interval, double-sided, was 8.12 pg/mL (95% CI 6.77-9.45) and the upper limit was 29.00 pg/mL (95% CI 27.01-31.00)., Conclusion: The present study proposes reference values for plasma Aβ 1-42 . Nevertheless, further studies are needed to confirm these results and corroborate the use of these reference values in clinical practice., (Copyright © 2018 Elsevier B.V. All rights reserved.)

Introduction: Over 2 million people in high-income countries live with HIV. Early diagnosis and treatment present benefits for infected subjects and reduce secondary transmissions. Cost-effectiveness analyses are important to effectively inform policy makers and consequently implement the most cost-effective programmes. Therefore, we conducted a systematic review regarding the cost-effectiveness of HIV screening in high-income countries., Methods: We followed PRISMA statements and included all papers evaluating the cost-effectiveness of HIV screening in the general population or in specific subgroups., Results: Thirteen studies considered routine HIV testing in the general population. The most cost-effective option appeared to be associating one-time testing of the general population with annual screening of high-risk groups, such as injecting-drug users. Thirteen studies assessed the cost-effectiveness of HIV screening in specific settings, outlining the attractiveness of similar programmes in emergency departments, primary care, sexually transmitted disease clinics and substance abuse treatment programmes., Discussion: Evidence regarding the health benefits and cost-effectiveness of HIV screening is growing, even in low-prevalence countries. One-time screenings offered to the adult population appear to be a valuable choice, associated with repeated testing in high-risk populations. The evidence regarding the benefits of using a rapid test, even in terms of cost-effectiveness, is growing. Finally, HIV screening seems useful in specific settings, such as emergency departments and STD clinics., (Copyright © 2018 Elsevier B.V. All rights reserved.)

Introduction: Vertical transmission represents the major route of HIV infection for children. However, the preventive interventions available are extremely effective. This review summarizes evidence regarding the cost-effectiveness of mother-to-child-transmission preventive screenings, to help policy makers in choosing the optimal antenatal screening strategy., Methods: A systematic review following PRISMA guidelines was conducted, using 3 databases: PubMed, Scopus, and Cost-Effectiveness Analysis Registry. All articles regarding HIV screening to avoid vertical transmission were included., Results: The review included 21 papers. Seven studies assessed the cost-effectiveness of universal antenatal screening during early gestation. Two papers considered the integration of HIV screening with other medical interventions. Eight works estimated the cost-effectiveness of HIV screening in late pregnancy. Finally, 4 papers considered the combination of multiple strategies. The selected papers focused on both developed and developing countries, with a different HIV prevalence. The characteristics and methodology of the studies were heterogeneous. However, all studies agreed about the main findings, outlining the cost-effectiveness of both universal antenatal screening and HIV rescreening in late pregnancy. Cost-effectiveness improved when HIV burden increased. The major findings were proved to be robust across various scenarios when tested in sensitivity analysis., Conclusions: The review confirmed the cost-effectiveness not only of HIV universal antenatal screening but also of rescreening in late gestation in both developed and developing countries. Universal screening is cost-effective even in case of extremely low HIV prevalence. Therefore, to maximize screening, coverage appears as a worldwide priority. In certain settings, a targeted screening towards high-risk groups could be a valuable option., (Copyright © 2017 John Wiley & Sons, Ltd.)

Heterozygous loss of function mutations in granulin represent a significant cause of frontotemporal lobar degeneration with ubiquitin and TDP-43 inclusions (FTLD-TDP). We report a novel GRN splice site mutation (c.709-2 A>T), segregating with frontotemporal dementia spectrum in a large family from southern Italy. The GRN c.709-2 A>T is predicted to result in the skipping of exon 8, leading to non-sense mediated mRNA decay. Moreover, the PGRN plasma levels in the GRN c.709-2 A>T carriers were significantly lower (24 ng/ml) compared to controls (142.7 ng/ml) or family members non-carriers (82.0 ng/ml) (p-value = 0.005, Kruskal Wallis), suggesting progranulin haploinsufficiency. We do not report any potential pathogenic GRN mutation in a follow-up cohort composed of 6 FTD families and 43 sporadic FTD cases, from the same geographic area. Our study suggests that GRN (c.709-2 A>T) is a novel and likely very rare cause of FTD in this Italian cohort. Finally, in line with previous studies, we show that GRN haploinsufficiency leads to a heterogeneous clinical picture, and plasma progranulin levels may be a reliable tool to identify GRN loss of function mutations. However, given that a) genetic and environmental factors, gender, and age may regulate PGRN plasma levels and b) plasma progranulin levels may not reflect PGRN levels in the central nervous system, we suggest that the measurement of progranulin in the plasma should always be coupled with genetic screening of GRN for mutations.

Background: Neuropsychological rehabilitation efficacy in multiple sclerosis (MS) is a currently investigated issue. We reported, in a single blind controlled study, that an intensive short duration cognitive training of attention and executive functions significantly improves the treated functions and reduces depression in MS. The persistence of these effects over time are unknown., Objective: To evaluate the persistence over time of neuropsychological improvement due to cognitive training nine months after rehabilitation onset., Methods: This is a single blind randomized controlled study. 24 MS patients were randomly assigned to experimental group (n=13) and received PC assisted neuropsychological treatment for three months, or to control group (n=11), receiving no treatment. Patients were submitted to neuropsychological evaluation, depression and quality of life questionnaires at baseline, three months and nine months later., Results: Nine months follow up compared to baseline evaluation shows a statistically significant improvement (p<0.05) in attention, information processing and executive functions tests (PASAT 3″, COWA/S, WCSTpe), in depression and quality of life questionnaires in rehabilitated patients only. reliable change index (RCI) and modified RCI confirmed the clinical significance of this improvement in rehabilitated patients., Conclusions: Three months intensive neuropsychological rehabilitation of attention, information processing and executive functions induces a long lasting and clinically relevant neuropsychological improvement over time and a persistent depression and quality of life amelioration in patients with RR MS., (Copyright © 2012 Elsevier B.V.

Objective: To evaluate the efficacy of a computer-based intensive training program of attention, information processing and executive functions in patients with clinically-stable relapsing-remitting (RR) multiple sclerosis (MS) and low levels of disability. DESIGN, PATIENTS AND INTERVENTIONS: A total of 150 patients with RR MS and an Expanded Disability Status Scale (EDSS) score of < or =4 were examined. Information processing, working memory and attention were assessed by the Paced Auditory Serial Addition Test (PASAT) and executive functions by the Wisconsin Card Sorting Test (WCST). Twenty patients who scored below certain cut-off measures in both tests were included in this double-blind controlled study. Patients were casually assigned to a study group (SG) or a control group (CG) and underwent neuropsychological evaluation at baseline and after 3 months. Patients in the SG received intensive computer-assisted cognitive rehabilitation of attention, information processing and executive functions for 3 months; the CG did not receive any rehabilitation., Setting: Ambulatory patients were sent by the MS referral center., Outcome Measures: Improvement in neuropsychological test and scale scores., Results: After rehabilitation, only the SG significantly improved in tests of attention, information processing and executive functions (PASAT 3'' p=0.023, PASAT 2'' p=0.004, WCSTte p=0.037), as well as in depression scores (MADRS p=0.01). Neuropsychological improvement was unrelated to depression improvement in regression analysis., Conclusions: Intensive neuropsychological rehabilitation of attention, information processing and executive functions is effective in patients with RR MS and low levels of disability, and also leads to improvement in depression.

Autonomous sensors play a very important role in the environmental, structural, and medical fields. The use of this kind of systems can be expanded for several applications, for example in implantable devices inside the human body where it is impossible to use wires. Furthermore, they enable measurements in harsh or hermetic environments, such as under extreme heat, cold, humidity or corrosive conditions. The use of batteries as a power supply for these devices represents one solution, but the size, and sometimes the cost and unwanted maintenance burdens of replacement are important drawbacks. In this paper passive and self-powered autonomous sensors for harsh or hermetical environments without batteries are discussed. Their general architectures are presented. Sensing strategies, communication techniques and power management are analyzed. Then, general building blocks of an autonomous sensor are presented and the design guidelines that such a system must follow are given. Furthermore, this paper reports different proposed applications of autonomous sensors applied in harsh or hermetic environments: two examples of passive autonomous sensors that use telemetric communication are proposed, the first one for humidity measurements and the second for high temperatures. Other examples of self-powered autonomous sensors that use a power harvesting system from electromagnetic fields are proposed for temperature measurements and for airflow speeds.
