Bloodstream infections due to multi-drug resistant bacteria in the emergency department: prevalence, risk factors and outcomes-a retrospective observational study.

Multidrug-resistant organisms (MDROs) are prevalent in patients admitted to the Emergency Department (ED) and increase the risk of inappropriate empirical antibiotic therapy. Risk stratification for MDRO infection is essential to early identify patients requiring empirical broad-spectrum antibiotic therapy, but it remains challenging for emergency physicians. This study aimed to evaluate prevalence, risk factors, and outcomes of patients admitted to the ED with a bloodstream infection (BSI) caused by MDROs. A retrospective observational study enrolling all consecutive adult patients admitted with a BSI to the ED of Niguarda Hospital, Italy, from January 2019 to December 2021 was performed. 757 patients were enrolled, 14.1% with septic shock. 156 (20%) patients had a BSI caused by MDRO: extended-spectrum beta-lactamase (ESBL) producing Enterobacterales were the most prevalent followed by methicillin-resistant Staphylococcus aureus (MRSA). Risk factors for BSI due to MDRO and specifically for ESBL were chronic renal failure (OR 2.2; 95%CI 1.4-3.6), nursing home residency (OR 4.4; 95%CI 1.9-10.2) and antibiotic therapy in the last 90-days (OR 2.6; 95%CI 1.7-4), whereas for MRSA were dialysis (OR 12.3; 95%CI 1.8-83), antibiotic therapy and/or hospital admission in the past 90-days (OR 3.6; 95%CI 1.2-10.6) and ureteral stent or nephrostomy (OR 7.8; 95%CI 1.5-40.9). Patients with BSI due to MDRO had a higher rate of inappropriate empirical antibiotic therapy (50%) and longer length of stay, but no higher in-hospital mortality. Among patients admitted to the ED with a BSI, MDROs are frequent and often associated with inappropriate empirical antibiotic therapy. Specific updated risk factors for MDRO may help clinicians to better identify patients requiring a broader antibiotic therapy in the ED, while awaiting microbiological results.

Thymic Stromal Lymphopoietin and Tezepelumab in Airway Diseases: From Physiological Role to Target Therapy.

Thymic stromal lymphopoietin (TSLP), is a protein belonging to a class of epithelial cytokines commonly called alarmins, which also includes IL-25 and IL-33. Functionally, TSLP is a key player in the immune response to environmental insults, initiating a number of downstream inflammatory pathways. TSLP performs its role by binding to a high-affinity heteromeric complex composed of the thymic stromal lymphopoietin receptor (TSLPR) chain and IL-7Rα. In recent years, the important role of proinflammatory cytokines in the etiopathogenesis of various chronic diseases such as asthma, chronic rhinosinusitis with nasal polyposis (CRSwNP), chronic obstructive pulmonary diseases (COPDs), and chronic spontaneous urticaria has been studied. Although alarmins have been found to be mainly implicated in the mechanisms of type 2 inflammation, studies on monoclonal antibodies against TSLP demonstrate partial efficacy even in patients whose inflammation is not definable as T2 and the so-called low T2. Tezepelumab is a human anti-TSLP antibody that prevents TSLP-TSLPR interactions. Several clinical trials are evaluating the safety and efficacy of Tezepelumab in various inflammatory disorders. In this review, we will highlight major recent advances in understanding the functional role of TSLP, its involvement in Th2-related diseases, and its suitability as a target for biological therapies.

The importance of observing the master's hand: Action Observation Training promotes the acquisition of new musical skills.

Introduction: Via mirror mechanism, motor training approaches based on the alternation of action observation and execution (i.e., Action Observation Training-AOT) promote the acquisition of motor abilities. Previous studies showed that both visual and auditory stimuli may elicit a common motor representation of music-related gestures; however, the potentialities of AOT for the acquisition of musical skills are still underexplored. Methods: Twenty-one music-naïve participants underwent two blocks of training: AOT and Key-light Observation Training (KOT). AOT consisted of the observation of a melodic sequence played on a keyboard with the right hand by an expert model, followed by participant's imitation. Observation and execution were repeated six consecutive times (T1-T6). KOT followed the same procedure, except for the visual content of the stimulus, depicting the sequential highlighting of the piano keys corresponding to the melody. The rate of correct notes (C), the trainee-model similarity of key-pressure strength (S), and the trainee-model consistency of note duration (R) were collected across T1-T6. Results: Both AOT and KOT improved musical performance. Noteworthy, AOT showed a higher learning magnitude relative to KOT in terms of C and S. Discussion: Action Observation Training promotes the acquisition of key elements of melodic sequences, encompassing not only the accurate sequencing of notes but also their expressive characteristics, such as key-pressure dynamics. The convergence of listening and observation of actions onto a shared motor representation not only explains several pedagogical approaches applied in all musical cultures worldwide, but also enhances the potential efficacy of current procedures for music training.

School victimization and psychosocial adjustment among Eastern European adopted adolescents across Europe.

BACKGROUND: Little is known about bullying experienced by internationally adopted teens residing in Europe. OBJECTIVES: Within the framework of an international research effort involving several European countries, the main goal of this study was to explore the experiences of bullying victimization suffered by adopted adolescents, as well as its impact on their psychological adjustment. METHODS: The sample consisted of 199 adolescents born in Eastern European countries and adopted in France (n = 50), Italy (n = 59), Norway (n = 25) and Spain (n = 65). RESULTS: More than half of the adopted adolescents had been exposed to some form of peer victimization in the previous 2 months, with verbal harassment and social exclusion being the most common forms of victimization. Differences between receiving countries were not statistically significant, suggesting a common pattern for Eastern European adopted adolescents living in Western Europe. More frequent experiences of peer victimization were associated with more psychological difficulties among the adopted adolescents. CONCLUSIONS: Findings highlight that adopted adolescents might have considerable difficulties in social integration with peers; these experiences of peer victimization might play an important role hindering their psychosocial adjustment. The socioemotional development of adopted people is not only linked to their pre-adoptive experiences; factors in their daily lives (i.e., peer relationships) may also be associated with their psychological adjustment later in life. Interventions are needed to promote the real inclusion of these groups of children in their social and educational contexts.

Moderate asthma: burden, mechanisms and therapeutic perspectives.

PURPOSE OF REVIEW: Global Initiative for Asthma (GINA) document provides a classification of asthma severity according with the current level of treatment required to achieve diseases control and underlines the limitations of this approach. In this review, we will provide an overview of recent investigations that have analyzed clinical and molecular features of moderate asthma. RECENT FINDINGS: Moderate asthma is heterogeneous in terms of response to inhaled treatment and pathogenetic mechanisms underlying the clinical features. Analysis of inflammatory pathways in patients who do not achieve disease remission allows identification of patient subgroups that may benefit from specific biological treatments. SUMMARY: Scientific progress makes increasingly clear that there are biological mechanisms capable of identifying and justifying the degree of severity of asthma. The identification of these, combined with the development of new pharmacological treatments, will be the cornerstones of improving the management of asthma in its degrees of severity.

Long-Term Efficacy of Mepolizumab at 3 Years in Patients with Severe Asthma: Comparison with Clinical Trials and Super Responders.

The efficacy mepolizumab in severe asthmatic patients is proven in the literature. Primarily to study the effect of mepolizumab on exacerbations, steroid dependence, and the continuation of efficacy in the long term. Secondarily to evaluate the effect of the drug on nasal polyps. Analyzing data from SANI (Severe Asthma Network Italy) clinics, we observed severe asthmatic patients treated with mepolizumab 100 mg/4 weeks, for a period of 3 years. 157 patients were observed. Exacerbations were reduced from the first year (-84.6%) and progressively to 90 and 95% in the second and third ones. Steroid-dependent patients decreased from 54% to 21% and subsequently to 11% in the second year and 6% in the third year. Patients with concomitant nasal polyps, assessed by SNOT-22, showed a 49% reduction in value from baseline to the third year. The study demonstrated the long-term efficacy of mepolizumab in a real-life setting.

The enduring role of sense of coherence in facing the pandemic.

Research has been focussing on protective and resistance-related factors that may help people face the long-lasting psychological challenges of the COVID-19 pandemic. Sense of coherence allows to remain healthy and to recover after stressful or traumatic life experiences. We aimed at investigating whether, and the extent to which, social support, in terms of both family and friends support, mediated the well-established link between sense of coherence and mental health as well as that between sense of coherence and COVID-19-related Post-Traumatic Stress Disorder (PTSD) symptoms. In May 2021, 3048 Italian respondents (51.5% women) aged between 18 and 91 (Mage = 48.33, SD = 14.04) filled in a self-report questionnaire. The mediation analyses we carried out on their responses showed a difference between focussing on mental health or on a psychological disorder. Indeed, despite the respectively positive and negative relation between sense of coherence and mental health and PTSD symptoms, this confirming the protective role of sense of coherence more than 1 year after the beginning of the pandemic, social support only mediated, partially, the former link. We also discuss practical implications and further expansion of the study.

The capacity of action observation to drag the trainees' motor pattern toward the observed model.

Action Observation Training (AOT) promotes the acquisition of motor abilities. However, while the cortical modulations associated with the AOT efficacy are well known, few studies investigated the AOT peripheral neural correlates and whether their dynamics move towards the observed model during the training. We administered seventy-two participants (randomized into AOT and Control groups) with training for learning to grasp marbles with chopsticks. Execution practice was preceded by an observation session, in which AOT participants observed an expert performing the task, whereas controls observed landscape videos. Behavioral indices were measured, and three hand muscles' electromyographic (EMG) activity was recorded and compared with the expert. Behaviorally, both groups improved during the training, with AOT outperforming controls. The EMG trainee-model similarity also increased during the training, but only for the AOT group. When combining behavioral and EMG similarity findings, no global relationship emerged; however, behavioral improvements were "locally" predicted by the similarity gain in muscles and action phases more related to the specific motor act. These findings reveal that AOT plays a magnetic role in motor learning, attracting the trainee's motor pattern toward the observed model and paving the way for developing online monitoring tools and neurofeedback protocols.

Tailoring inkjet-printed PEDOT:PSS composition toward green, wearable device fabrication.

Inkjet printing remains one of the most cost-efficient techniques for device prototyping and manufacturing, offering considerable freedom of digital design, non-contact, and additive fabrication. When developing novel wearable devices, a balanced approach is required between functional, user-safe materials and scalable manufacturing processes. Here, we propose a tailor-made ink formulation, based on non-hazardous materials, to develop green electronic devices aimed at interfacing with humans. We demonstrate that developed ink exhibits high-resolution inkjet printability, in line with theoretical prediction, on multiple wearable substrates. The ink's chemical composition ensures the pattern's enhanced electrical properties, mechanical flexibility, and stability in water. The cytocompatibility evaluations show no noxious effects from printed films in contact with human mesenchymal stem cells. Finally, we fabricated a printed wearable touch sensor on a non-woven fabric substrate, capable of tracking human steps. This is a step toward the development of green wearable electronics manufacturing, demonstrating a viable combination of materials and processes for biocompatible devices.

Central venous catheters-related-thrombosis and risk factors in oncological patients: A retrospective evaluation of recent risk scores.

BACKGROUND: Insertions of central venous catheters (CVC) has become a common practice in Onco-Hematologic Units to administer systemic treatments. Unfortunately they can cause complications influencing patient's care-pathway significantly. Oncological patients have a higher thrombotic risk than the general population, therefore specific recent risk scores are spreading through the clinical practice, such as Khorana, Protecht, COMPASS-CAT, and Michigan scores. METHODS: A retrospective cohort of 177 out of a total of 3046 outpatients accessing the Medical Day Hospital of Istituto Nazionale Tumori di Milano from March 2019 to February 2021 aged ⩾ 18 years who developed CVC complications was analyzed extracting clinical data from their medical records. Focusing on the risk factors, especially through recent risk scores to estimate the thrombotic risk we used Wilcoxon-test for continuous variables and the Pearson-Chi-Square test for categorical variables. RESULTS: Anticoagulants resulted a protective factor mostly for partial CVC occlusion (p = 0.0001), preventing CVC occlusions. CVC occlusions were significantly associated with epitelial tumor histotype, (p = 0.0061). Complete CVC occlusions were significantly associated with peripherical inserted central venous catheters (PICC) (p < 0.0001). Catheter-related-thrombosis (CRT) was significantly associated with peripherical-inserted-central-venous-catheter, both when it was diagnosed clinically (p = 0.0121) and radiographically (p = 0.0168).There was a strong association between CRT and a high grade of Khorana Score (p = 0.0195), Protecht Score (p = 0.0412), COMPASS-CAT Score (p = 0.0027). A positive statistical trend was observed between the Michigan Score and CRT in patients carrying PICC (p = 0.053). CONCLUSIONS: There are many different and various factors associated with higher or lower risk of CVC thrombotic complications, so it could be useful to test the recent risk scores to estimate thrombotic risk in oncological patients in clinical practice.

COVID-19-Related Stress and Resilience Resources: A Comparison Between Adoptive and non-Adoptive Mothers.

Despite an increasing interest in how adoptive parents deal with situations appraised as stressful, there is a lack of research regarding adoptive parents' adjustment to the challenges posed by the prolonged COVID-19 pandemic. The current study explores similarities and differences between adoptive and non-adoptive mothers in terms of risks (i.e., COVID-19-related stress) and individual (i.e., sense of coherence [SOC]), couple (i.e., partner's support), parent-child (i.e., parent-child relationship satisfaction), and social (i.e., friends' support) resources in the face of the prolonged COVID-19 pandemic. Specifically, the present study was aimed at predicting which variables discriminate more effectively between the two groups. Participants were 445 Italian mothers (40.9% adoptive mothers), who were asked to fill in an anonymous online survey between May 2021 and October 2021. Results showed that adoptive and non-adoptive mothers reported different resilience resources to face the stressors posed by the health emergency. Specifically, COVID-19 traumatic stress symptoms, parent-child relationship satisfaction, and SOC were found to contribute most in discriminating between the two groups. Findings are discussed in relation to future research developments and practical implications.

Nasal cytology as a reliable non-invasive procedure to phenotype patients with type 2 chronic rhinosinusitis with nasal polyps.

Background: The identification of type-2 inflammation in patients with chronic rhinosinusitis with nasal polyps (CRSwNP) acquires a crucial role in the endotypization needed for selecting patients for biological drugs targeting type-2 inflammation: to date, the parameters used include systemic and histological biomarkers. The aim of this study was to investigate whether nasal cytology could identify type-2 inflammation in patients with CRSwNP. Methodology: Thirty-three consecutive patients with CRSwNP underwent nasal cytology sampling at the level of the lower nasal turbinate, and of the polypoid tissue, and surgical polyp tissue sample was collected. The cellularity of the 3 collected samples were compared. Results: Mean nasal polyp tissue, nasal polyps cytology and inferior turbinate cytology eosinophils counts were 43.7 ± 39.6 cells/HPF, 32.8 ± 44.7 cells/HPF and 27.6 ± 58.0 cells/HPF respectively with inferior turbinate cytology eosinophils significantly lower than nasal polyp tissue count (p = 0.007). Both mean nasal polyps cytology eosinophils and mean inferior turbinate cytology eosinophils were significantly higher in patients with type-2 CRSwNP (52.5 ± 67.0 cells/HPF vs 12.2 ± 17.3 cells/HPF, p = 0.012, and 32.0 ± 62.1 cells/HPF vs 2.9 ± 2.9 cells/HPF, p = 0.020 respectively). Conclusions: Nasal cytology is suitable tool for assessing local biomarkers of type-2 inflammation in CRSwNP.

Conformable Wearable Electrodes: From Fabrication to Electrophysiological Assessment.

Wearable electronic devices are becoming key players in monitoring the body signals predominantly altered during physical activity tracking. Considering the growing interest in telemedicine and personalized care driven by the rise of the Internet of Things era, wearable sensors have expanded their field of application into healthcare. To ensure the collection of clinically relevant data, these devices need to establish conformable interfaces with the human body to provide high-signal-quality recordings and long-term operation. To this end, this paper presents a method to easily fabricate conformable thin tattoo- and soft textile-based sensors for their application as wearable organic electronic devices in a broad spectrum of surface electrophysiological recordings. The sensors are developed through a cost-effective and scalable process of cutaneous electrode patterning using poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate) (PEDOT:PSS), the most popular conductive polymer in bioelectronics, on off-the-shelf, wearable substrates. This paper presents key steps in electrode characterization through impedance spectroscopy to investigate their performance in signal transduction when coupled with the skin. Comparative studies are required to position the performance of novel sensors with respect to the clinical gold standard. To validate the fabricated sensors' performance, this protocol shows how to perform various biosignal recordings from different configurations through a user-friendly and portable electronic setup in a laboratory environment. This methods paper will allow multiple experimental initiatives to advance the current state of the art in wearable sensors for human body health monitoring.

Interdigitated Organic Sensor in Multimodal Facemask's Barrier Integrity and Wearer's Respiration Monitoring.

Facemasks are used as a personal protective equipment in medical services. They became compulsory during the recent COVID-19 pandemic at large. Their barrier effectiveness during various daily activities over time has been the subject of much debate. We propose the fabrication of an organic sensor to monitor the integrity of surgical masks to ensure individuals' health and safety during their use. Inkjet printing of an interdigitated conducting polymer-based sensor on the inner layer of the mask proved to be an efficient and direct fabrication process to rapidly reach the end user. The sensor's integration happens without hampering the mask functionality and preserving its original air permeability. Its resistive response to humidity accumulation allows it to monitor the mask's wetting in use, providing a quantified way to track its barrier integrity and assist in its management. Additionally, it detects the user's respiration rate as a capacitive response to the exhaled humidity, essential in identifying breathing difficulties or a sign of an infection. Respiration evaluations during daily activities show outstanding performance in relation to unspecific motion artifacts and breathing resolution. This e-mask yields an integrated solution for home-based individual monitoring and an advanced protective equipment for healthcare professionals.

Bullying victimization among internationally adopted adolescents: Psychosocial adjustment and moderating factors.

Bullying constitutes a serious risk factor for the psychosocial adjustment of young people in both the general population and minority groups. Among minorities, international adoptees are likely to show a specific vulnerability to the experience of being bullied, moderated by specific risk and protective factors. This study aimed to investigate the association between adoptees' experience of bullying victimization and their psychosocial adjustment, and to explore the moderating role of adoptive identity and reflected minority categorization. An online, anonymous self-report questionnaire was completed by 140 adolescents (13-17 years), who were internationally adopted by Italian families. Findings showed that being victimized was associated with higher levels of emotional and behavioral difficulties, but that the strength of this relation varied according to the levels of adoptive identity and reflected minority categorization. Specifically, victimization was found to have a more detrimental and negative impact on psychological adjustment for adoptees who were highly identified with the adoptive group, and reported to be less perceived by others as members of the minority group. Results are discussed in relation to recommendations for further research as well as for professionals working with internationally adopted adolescents.

Bicultural identity in childhood: Preliminary validation of the Bicultural Identity Integration Scale for Children (BIIS-C).

OBJECTIVE: In the present study, we adapted and validated the Bicultural Identity Integration Scale for Children (BIIS-C). METHOD: 259 bicultural children (119 males, 140 females; Mage = 11.07, SD = 1.24) were provided with a questionnaire. Based on adult versions of the scale, we tested the factorial structure of a set of 11 nonreversed items tapping into harmony (vs. conflict; six items) and blendedness (vs. compartmentalization; five items) dimensions. RESULTS: A two-factor model was compared with a one-factor model. In line with research on adults, results showed that the two-factor model (with nine items) fitted the data better than the one-factor model. The two dimensions yielded reliable scores and were correlated in the expected direction with personality variables, acculturation attitudes, and perceived discrimination. CONCLUSIONS: The BIIS-C provides valid and reliable scores for research on biculturalism in childhood. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

The quiet migration of adopted adolescents in Italy: Ethnic identity, reflected minority categorization, and ethnic discrimination.

Internationally adopted adolescents face the crucial developmental task of shaping their ethnic identity by balancing their dual belongingness to the current cultural background and the birth country's ethnic background. This process does not depend exclusively on individual variables, but it is embedded within the social context. The present study was aimed at exploring the role of ethnic discrimination in moderating the association between reflected minority categorization, on the one hand, and ethnic identity, on the other. A self-report questionnaire was administrated to 180 internationally adopted adolescents. Results showed that at high levels of ethnic discrimination the relation between reflected minority categorization and ethnic identity in terms of commitment was negative and stronger. When considering instead ethnic identity in terms of exploration, it is possible to note that higher levels of reflected minority categorization were associated with higher levels of exploration. Findings are discussed in light of post-adoption intervention for adoptees.

Severe asthma: One disease and multiple definitions.

INTRODUCTION: There is, so far, no universal definition of severe asthma. This definition usually relies on: number of exacerbations, inhaled therapy, need for oral corticosteroids, and respiratory function. The use of such parameters varies in the different definitions used. Thus, according to the parameters chosen, each patient may result in having severe asthma or not. The aim of this study was to evaluate how the choice of a specific definition of severe asthma can change the allocation of patients. METHODS: Data collected from the Severe Asthma Network Italy (SANI) registry were analyzed. All the patients included were then reclassified according to the definitions of U-BIOPRED, NICE, WHO, ATS/ERS, GINA, ENFUMOSA, and TENOR. RESULTS: 540 patients, were extracted from the SANI database. We observed that 462 (86%) met the ATS/ERS criteria as well as the GINA criteria, 259 (48%) the U-Biopred, 222 (41%) the NICE, 125 (23%) the WHO, 313 (58%) the Enfumosa, and 251 (46%) the TENOR criteria. The mean eosinophil value were similar in the ATS/ERS, U-Biopred, and Enfumosa (528, 532 and 516 cells/mcl), higher in WHO and Tenor (567 and 570 cells/mcl) and much higher in the NICE classification (624 cells/mcl). Lung function tests resulted similarly in all groups, with WHO (67%) and ATS/ERS-GINA (73%), respectively, showing the lower and upper mean FEV1 values. CONCLUSIONS: The present observations clearly evidence the heterogeneity in the distribution of patients when different definitions of severe asthma are used. However, the recent definition of severe asthma, provided by the GINA document, is similar to that indicated in 2014 by ATS/ERS, allowing mirror reclassification of the patients examined. This lack of homogeneity could complicate the access to biological therapies. The definition provided by the GINA document, which reflects what suggested by ATS/ERS, could partially overcome the problem.

Perceived Changes in Family Life During COVID-19: The Role of Family Size.

OBJECTIVE: The current study was aimed at exploring Italian parents' perceived negative and positive changes in family life during the COVID-19 pandemic, taking into account the role of the stage of the family life and family size. BACKGROUND: During the emergency of the COVID-19 pandemic, millions of families drastically changed their daily life and routines. Little evidence exists on how family characteristics, such as family size or presence of children, are related to families' experience of family change. METHOD: A large sample of 1,407 Italian parents (70.1% mothers) filled in an anonymous online survey during the third week of the lockdown period (between March 30 and April 7, 2020). RESULTS: Results showed that parents reported perceiving more positive changes than negative ones, especially in terms of feeling more emotionally close to their children and spending more fun time with them. Interestingly, parents with two or more children reported more positive changes in family life compared with parents who had one child, showing a greater relational regenerative capacity in the face of COVID-19 lockdown. CONCLUSION AND IMPLICATIONS: Investing in family relationships, especially for larger families, is an effective coping strategy to deal with traumatic situations and promote positive family changes in stressful situations.
