Axicabtagene ciloleucel treatment is more effective in primary mediastinal large B-cell lymphomas than in diffuse large B-cell lymphomas: the Italian CART-SIE study

Axicabtagene ciloleucel showed efficacy for relapsed/refractory large B-cell lymphomas (LBCL), including primary mediastinal B-cell lymphomas (PMBCL); however, only few PMBCLs were reported. Aim was to evaluate efficacy and safety of axicabtagene ciloleucel in patients with PMBCL compared to those with other LBCL, enrolled in the Italian prospective observational CART-SIE study. PMBCLs (n = 70) were younger, with higher percentage of bulky and refractory disease, compared to other LBCLs (n = 190). Median follow-up time for infused patients was 12.17 months (IQR 5.53,22.73). The overall (complete + partial) response rate (ORR,CR + PR) after bridging was 41% for PMBCL and 28% for other LBCL, p = 0.0102. Thirty days ORR was 78% (53/68) with 50% (34) CR in PMBCL, and 75% (141/187) with 53% (100) CR in other LBCL, p = 0.5457. Ninety days ORR was 69% (45/65) with 65% (42) CR in PMBCL, and 54% (87/162) with 47% (76) CR in other LBCL; progressive disease was 21% in PMBCL and 45% in other LBCL, p = 0.0336. Twelve months progression-free survival was 62% (95% CI: 51-75) in PMBCL versus 48% (95% CI: 41-57) in other LBCL, p = 0.0386. Twelve months overall survival was 86% (95% CI: 78-95) in PMBCL versus 71% (95% CI: 64-79) in other LBCL, p = 0.0034. All grade cytokine release syndrome was 88% (228/260); all grade neurotoxicity was 34% (88/260), with 6% of fatal events in PMBCL. Non-relapse mortality was 3%. In conclusion, PMBCLs achieved significantly better response and survival rates than other LBCLs.

The interplay between mentalization, personality traits and burnout in psychiatry training: Results from a large multicenter controlled study

BACKGROUND

A better characterization of educational processes during psychiatry training is needed, both to foster personal resilience and occupational proficiency.

METHODS

An adequate coverage of medical residents at the national level was reached (41.86% of the total reference population, 29 out of 36 training centers-80.55%). Controls were recruited among residents in other medical specialties. All participants were assessed by questionnaires to evaluate early life experiences, attachment style, personality traits, coping strategies, emotional competencies. A Structural Equation Model (SEM) framework was employed to investigate the interplay between individual factors.

RESULTS

A total sample of 936 people was recruited (87.9% response-rate; 645 residents in psychiatry, 291 other medical residents). Psychiatry trainees reported a higher prevalence of adverse childhood experiences (emotional abuse, emotional neglect, physical neglect), greater attachment insecurity (anxious or avoidant) in comparison to other medical trainees. Psychiatry residents also reported higher social support-seeking as a coping strategy, lower problem-orientation, and lower transcendence. Lower neuroticism, higher openness to experience, and higher emotional awareness were also observed in psychiatry trainees. Psychiatry training was associated with a redefinition of conflict management skills as a function of seniority. The SEM model provided support for an interplay between early traumatic experiences, mentalization skills (coping strategies, emotion regulation), interpersonal competencies and occupational distress.

CONCLUSIONS

The findings of the present study supported a theoretical model based on mentalization theory for the interactions between personal and relational competencies in psychiatry training, thus providing potential target of remodulation and redefinition of this specific process of education.

Microaggression toward LGBTIQ people and implications for mental health: A systematic review

BACKGROUND

Research suggests that microaggressions detrimentally impact the mental health of members of marginalized social groups.

AIMS

The aim of this systematic review was to assess the exposure to microaggressions and related implications on mental health of Lesbian, Gay, Bisexual, Transgender, Intersex, and Queer (LGBTIQ) people.

METHOD

Medline, Scopus, PsycINFO, CINAHL, and EMBASE were searched until January 2023. Studies reporting data on the exposure to microaggressions toward LGBTIQ people were identified. Meta-analyses of rates of exposure to microaggression and of the association between microaggressions and mental health outcomes were based on odds ratio (OR) and standardized mean difference (SMD) with 95% confidence intervals (95% CI), estimated through inverse variance models with random effects.

RESULTS

The review process led to the selection of 17 studies, involving a total of 9036 LGBTIQ people, of which 6827 identifying as cisgenders, and 492 as heterosexuals, were included in the quantitative synthesis. Overall, LGBTIQ people showed an increased risk of microaggression (SMD: 0.89; 95% CI [0.28, 1.50]), with Transgender people having the highest risk (OR: 10.0; 95% CI [3.08, 32.4]). Microaggression resulted associated with risk of depression (SMD: 0.21; 95% CI [0.05, 0.37]), anxiety (SMD: 0.29; 95% CI [0.17, 0.40]), suicide attempts (OR: 1.13; 95% CI [1.08, 1.18]), alcohol abuse (OR: 1.32; 95% CI [1.13, 1.54]), but not to suicidal ideation (OR: 1.56; 95% CI [0.64, 3.81]) and cannabis abuse (OR: 1.44; 95% CI [0.82, 2.55]). The quality of the evidence was limited by the small number of studies.

CONCLUSIONS

LGBTIQ people are at higher risk of microaggressions compared with their cisgender/heterosexual peers, which may lead to mental health consequences. This evidence may contribute to public awareness of LGBTIQ mental health needs and suggest supportive strategies as well as preventive interventions (e.g., supportive programs and destigmatizing efforts) as parts of tailored health-care planning aimed to reduce psychiatric morbidity in this population.

Perioperative pain management after scapular tip free flap harvesting for head and neck reconstruction using mini-catheters to inject the local anesthetic

PURPOSE

Although functional and esthetic results after the use of a scapular tip free flap (STFF) in head and neck reconstruction, and the related donor-site morbidity, have been extensively described, data regarding acute postoperative donor-site pain management are lacking. Purpose of this study is to explore the use of mini-catheters to administer local anesthetics for donor-site pain management after reconstruction using STFF.

METHODS

Patients who underwent head and neck reconstruction using a STFF were prospectively enrolled and, through a perineural catheter placed in the donor site during the surgical procedure, a bolus of chirochaine was injected before the patient regained consciousness and at 8, 16, and 24 h postoperatively. Before and 40 min after each dose administration, donor-site pain on a numerical rating scale (NRS; 0-10) was evaluated.

RESULTS

Study population consisted of 20 patients (40-88 years). At 8 h, the pain scores before and after the injection were 0-10 (mean 3.35) and 0-5 (mean 1.25), respectively. At 16 h, the pain scores before and after the injection were 0-8 (mean 2.55) and 0-4 (mean 0.55), respectively. At 24 h, the pain scores before and after the injection were 0-8 (mean 1.30) and 0-4 (mean 0.30), respectively.

CONCLUSION

Statistical analysis confirmed a significant difference between the pain scores before and after administration at 8, 16, and 24 h (p < 0.001, p < 0.001, and p = 0.003, respectively). Mini-catheters for local anesthetic administration represent an effective strategy for pain control after STFF harvesting for head and neck reconstruction.

Idiopathic erythrocytosis: a germline disease?

Polycythemia Vera (PV) is typically caused by V617F or exon 12 JAK2 mutations. Little is known about Polycythemia cases where no JAK2 variants can be detected, and no other causes identified. This condition is defined as idiopathic erythrocytosis (IE). We evaluated clinical-laboratory parameters of a cohort of 56 IE patients and we determined their molecular profile at diagnosis with paired blood/buccal-DNA exome-sequencing coupled with a high-depth targeted OncoPanel to identify a possible underling germline or somatic cause. We demonstrated that most of our cohort (40/56: 71.4%) showed no evidence of clonal hematopoiesis, suggesting that IE is, in large part, a germline disorder. We identified 20 low mutation burden somatic variants (Variant allelic fraction, VAF, < 10%) in only 14 (25%) patients, principally involving DNMT3A and TET2. Only 2 patients presented high mutation burden somatic variants, involving DNMT3A, TET2, ASXL1 and WT1. We identified recurrent germline variants in 42 (75%) patients occurring mainly in JAK/STAT, Hypoxia and Iron metabolism pathways, among them: JAK3-V722I and HIF1A-P582S; a high fraction of patients (48.2%) resulted also mutated in homeostatic iron regulatory gene HFE-H63D or C282Y. By generating cellular models, we showed that JAK3-V722I causes activation of the JAK-STAT5 axis and upregulation of EPAS1/HIF2A, while HIF1A-P582S causes suppression of hepcidin mRNA synthesis, suggesting a major role for these variants in the onset of IE.

Involuntary Hospitalizations in an Italian Acute Psychiatric Ward: A 6-Year Retrospective Analysis

Purpose

We evaluated the differences between demographic (age, sex, nationality, employment, housing, schooling, support administrator), clinical (hospitalization reason, aggressive behaviour, length of hospitalization, psychiatric diagnosis and comorbidities, psychiatric medications, discharge destination, "revolving door" hospitalizations) and environmental (pre-and pandemic period) variables in voluntary (VHs) and involuntary hospitalizations (IHs) in an acute psychiatric ward during a 6-year period.

Patients and Methods

We retrospectively collected the selected variables concerning the hospitalizations of subjects over 18 years of age in the Service for Psychiatric Diagnosis and Care of Mental Health and Drug Abuse Department in Modena from 01/01/2017 to 31/12/2022.

Results

We observed a progressive and sharp reduction in the number of VHs (n = 1800; 61.41%) during the pandemic and a stability of IHs (n = 1131; 38.59%), which in 2022 became prevalent. We highlighted the following differences between VHs and IHs: an increase in hospitalization length in IHs (14.25 mean days ± 15.89 SD) in comparison with VHs (8.78 mean days ± 13.88 SD), which increased more during the pandemic; an increase in aggressive behavior in IHs, especially during the pandemic (Pearson Chi2 = 90.80; p = 0.000); a prevalence of schizophrenia and bipolar disorders (Pearson Chi2 = 283.63; p = 0.000) and more frequent maladaptive social conditions among subjects in IHs.

Conclusion

During the 6-year observation period, we underscored a trend of increasingly reduced recourse to VHs, whereas IHs increased even in the pandemic. Our results suggest that IHs in Psychiatry represented an extreme measure for treating the most severe psychopathological situations such as schizophrenia and bipolar disorders, characterized by aggressive behaviour and precarious social conditions, which needed longer stay than VHs, especially during the pandemic.

Previous fracture and subsequent fracture risk: a meta-analysis to update FRAX

A large international meta-analysis using primary data from 64 cohorts has quantified the increased risk of fracture associated with a previous history of fracture for future use in FRAX.

INTRODUCTION

The aim of this study was to quantify the fracture risk associated with a prior fracture on an international basis and to explore the relationship of this risk with age, sex, time since baseline and bone mineral density (BMD).

METHODS

We studied 665,971 men and 1,438,535 women from 64 cohorts in 32 countries followed for a total of 19.5 million person-years. The effect of a prior history of fracture on the risk of any clinical fracture, any osteoporotic fracture, major osteoporotic fracture, and hip fracture alone was examined using an extended Poisson model in each cohort. Covariates examined were age, sex, BMD, and duration of follow-up. The results of the different studies were merged by using the weighted β-coefficients.

RESULTS

A previous fracture history, compared with individuals without a prior fracture, was associated with a significantly increased risk of any clinical fracture (hazard ratio, HR = 1.88; 95% CI = 1.72-2.07). The risk ratio was similar for the outcome of osteoporotic fracture (HR = 1.87; 95% CI = 1.69-2.07), major osteoporotic fracture (HR = 1.83; 95% CI = 1.63-2.06), or for hip fracture (HR = 1.82; 95% CI = 1.62-2.06). There was no significant difference in risk ratio between men and women. Subsequent fracture risk was marginally downward adjusted when account was taken of BMD. Low BMD explained a minority of the risk for any clinical fracture (14%), osteoporotic fracture (17%), and for hip fracture (33%). The risk ratio for all fracture outcomes related to prior fracture decreased significantly with adjustment for age and time since baseline examination.

CONCLUSION

A previous history of fracture confers an increased risk of fracture of substantial importance beyond that explained by BMD. The effect is similar in men and women. Its quantitation on an international basis permits the more accurate use of this risk factor in case finding strategies.

Thoughts and concerns of patients at hospital discharge after lumbar spine surgery. A qualitative study

PURPOSE

The increased rate of surgical interventions point to the necessity to investigate the patient's experience from a biopsychosocial perspective. The aim of this study was to investigate the thoughts and concerns of patients undergoing spinal surgery for lumbar degenerative disease at the time of their discharge from hospital.

METHODS

Semi-structured interviews were conducted with 28 patients. The questions investigated possible concerns associated to discharging them home. A content analysis was performed by a multidisciplinary group to identify the main themes that emerged from the interviews.

RESULTS

The patients were satisfied with the surgeons' preoperative explanations and description of expected prognosis. However, they were disappointed with the lack of information at hospital discharge, in particular regarding practical and behavioral recommendations. The patients expressed clear concerns about being left alone to deal with possible complications or difficulties they may encounter when returning home.

CONCLUSION

This study underlined the patients' need for a comprehensive psychological guidance and possibly a person of reference during the post-operative process. Discussing discharge with the patient was emphasized as an important issue to improve patients' compliance to the recovery process itself. Putting these elements into practice should help spine surgeons to manage better hospital discharge.IMPLICATIONS FOR REHABILITATIONA comprehensive discussion with the patient at the time of hospital discharge is clearly stressed as an important issue to improve patients' adherence to the recovery process.The patients complained of a lack of information when returning home, in particular regarding practical and behavioral recommendations.The patients expressed clear concerns about possible complications or difficulties they may encounter when returning home and they expressed their need to know whom they can contact for help if needed.A better understanding of the thoughts and concerns of patients undergoing spinal surgery at the time of their discharge from hospital should help spine surgeons to improve the management of hospital discharge and the post-operative recovery.

"Somewhere Between an Actual Disease and a Disease": A Grounded Theory Study on Diagnosing Functional Neurological Disorders From a Multi-Informant Perspective

Functional Neurological Disorders are characterized by sensory-motor or cognitive symptoms. Recent research has revealed their complex nature involving biological, psychological, and social factors. Care requires a multidisciplinary approach, which, to date, has yet to be considered. A Constructivist Grounded Theory study was conducted to understand the reasons behind this, exploring Functional Neurological Disorders diagnosis, communication, and understanding from multiple perspectives (patients and healthcare professionals). The core category was "negotiating Functional Neurological Disorders meanings and care amid a dissatisfying dichotomy," with sub-categories: i) seeking to "word" the disease, ii) exposing reductionism, and iii) a pluralist vision emerging. Diagnosing and communicating Functional Neurological Disorders is a process of negotiating meanings and care that hinges on participants' diverse ontological perspectives regarding the condition. Results highlight the difficulty in finding common ground and achieving mutual understanding among the various viewpoints, creating a challenge in establishing a unified approach to Functional Neurological Disorders care. In this context, only a few healthcare professionals emphasized the potential benefits of increased integration. A shift is required from a reductionist to an integrated biopsychosocial perspective to develop a more cohesive approach. Defining a medical paradigm through dialogue with teams and patients is essential in addressing Functional Neurological Disorders effectively. Furthermore, the required interdisciplinary approach holds the potential to mitigate the dissatisfaction arising from fragmented and compartmentalized care (the "dissatisfying dichotomy") experienced by our participants. It signifies a comprehensive strategy that could address the concerns of all involved parties and enhance the overall quality of care provided.

Unmet Psychosocial Needs of Health Care Professionals in Europe During the COVID-19 Pandemic: Mixed Methods Approach

BACKGROUND

The COVID-19 pandemic severely affected everyday life and working conditions for most Europeans, particularly health care professionals (HCPs). Over the past 3 years, various policies have been implemented in various European countries. Studies have reported on the worsening of mental health, work-related stress, and helpful coping strategies. However, having a closer look is still necessary to gain more information on the psychosocial stressors and unmet needs of HCPs as well as nonmedical staff.

OBJECTIVE

This study aimed to obtain quantitative information on job-related stressors of physicians and nurses and the coping strategies of HCPs and nonmedical staff at 2 periods of the COVID-19 pandemic. By further analyzing qualitative comments, we wanted to gain more information on the psychosocial stressors and unmet needs of HCPs as well as nonmedical staff on different levels of experience.

METHODS

A cross-sectional survey was conducted at 2 time points during the COVID-19 pandemic in several European countries. The first study period (T1) lasted between April 1 and June 20, 2020, and the second study period (T2) lasted between November 25, 2021, and February 28, 2022. On a quantitative level, we used a questionnaire on stressors for physicians and nurses and a questionnaire on coping strategies for HCPs and nonmedical staff. Quantitative data were descriptively analyzed for mean values and differences in stressors and coping strategies. Qualitative data of free-text boxes of HCPs and nonmedical staff were analyzed via thematic analysis to explore the experiences of the individuals.

RESULTS

T1 comprised 609 participants, and T2 comprised 1398 participants. Overall, 296 participants made 438 qualitative comments. The uncertainty about when the pandemic would be controlled (T1: mean 2.28, SD 0.85; T2: mean 2.08, SD 0.90) and the fear of infecting the family (T1: mean 2.26, SD 0.98; T2: mean 2.02, SD 1.02) were the most severe stressors identified by physicians and nurses in both periods. Overall, the use of protective measures (T1: mean 2.66, SD 0.60; T2: mean 2.66, SD 0.60) and acquiring information about COVID-19 (T1: mean 2.29, SD 0.82; T2: mean 1.99, SD 0.89) were identified as the most common coping strategies for the entire study population. Using thematic analysis, we identified 8 themes of personal experiences on the micro, meso, and macro levels. Measures, working conditions, feelings and emotions, and social climate were frequently mentioned topics of the participants. In T1, feelings of isolation and uncertainty were prominent. In T2, feelings of exhaustion were expressed and vaccination was frequently discussed. Moreover, unmet psychosocial needs were identified.

CONCLUSIONS

There is a need for improvement in pandemic preparedness. Targeted vocational education measures and setting up of web-based mental health support could be useful to bridge gaps in psychosocial support needs in future crises.

Air change rates and infection risk in school environments: Monitoring naturally ventilated classrooms in a northern Italian urban context

The importance of building ventilation in avoiding long-distance airborne transmission has been highlighted with the advent of the COVID-19 pandemics. Among others, school environments, in particular classrooms, present criticalities in the implementation of ventilation strategies and their impact on indoor air quality and risk of contagion. In this work, three naturally ventilated school buildings located in northern Italy have undergone monitoring at the end of the heating season. Environmental parameters, such as CO2 concentration and indoor/outdoor air temperature, have been recorded together with the window opening configurations to develop a two-fold analysis: i) the estimation of real air change rates through the transient mass balance equation method, and ii) the individual infection risk via the Wells-Riley equation. A strong statistical correlation has been found between the air change rates and the windows opening configuration by means of a window-to-volume ratio between the total opening area and the volume of the classroom, which has been used to estimate the individual infection risk. Results show that the European Standard recommendation for air renewal could be achieved by a window opening area of at least 1.5 m2, in the most prevailing Italian classrooms. Furthermore, scenarios in which the infector agent is a teacher show higher individual infection risk than those in which the infector is a student. In addition, the outcomes serve school staff as a reference to ensure adequate ventilation in classrooms and keep the risk of infection under control based on the number of the students and the volume of the classroom.

Efficacy and tolerability of desvenlafaxine in the real-world treatment of patients with major depression: a narrative review and an expert opinion paper

INTRODUCTION

Major depressive disorder (MDD) is a common severe mental disorder, requiring a tailored and integrated treatment. Several approaches are available including different classes of antidepressants various psychotherapeutic approaches, and psychosocial interventions. The treatment plan for each patient with MDD should be differentiated on the basis of several clinical, personal, and contextual factors.

AREAS COVERED

Desvenlafaxine - a serotonine-noradrenergic reuptake inhibitor (SNRI) antidepressant - has been approved in the United States in 2008 for the treatment of MDD in adults, and has been recently rediscovered by clinicians due to its good side-effect profile and its clinical effectiveness. A narrative review on efficacy, tolerability and use of desvenlafaxine in clinical practice was carried out. The keywords: 'major depression', 'depression,' 'desvenlafaxine,' 'efficacy,' 'clinical efficacy,' 'side effects', 'tolerability,' 'elderly patients', 'consultation-liaison', 'menopausal', 'young people', 'adolescent' were entered in PubMed, ISI Web of Knowledge, Scopus and Medline. No time limit was fixed, the search strategy was implemented on May 10, 2023.

EXPERT OPINION

Desvenlafaxine should be listed among the optimal treatment strategies for managing people with MDD, whose main strengths are: 1) ease of dosing; 2) favorable safety and tolerability profile, 3) absence of sexual dysfunctions, weight gain and low rate of discontinuation symptoms; 4) low risk of drug-drug interactions.

Post-traumatic stress disorder among LGBTQ people: a systematic review and meta-analysis

AIMS

Lesbian, gay, bisexual, transgender and queer people (LGBTQ) are at increased risk of traumatization. This systematic review aimed to summarize data regarding the risk of post-traumatic stress disorder (PTSD) for LGBTQ people and their subgroups.

METHODS

Medline, Scopus, PsycINFO and EMBASE were searched until September 2022. Studies reporting a comparative estimation of PTSD among LGBTQ population and the general population (i.e., heterosexual/cisgender), without restrictions on participants' age and setting for the enrolment, were identified. Meta-analyses were based on odds ratio (OR and 95% confidence intervals [CI]), estimated through inverse variance models with random effects.

RESULTS

The review process led to the selection of 27 studies, involving a total of 31,903 LGBTQ people and 273,842 controls, which were included in the quantitative synthesis. Overall, LGBTQ people showed an increased risk of PTSD (OR: 2.20 [95% CI: 1.85; 2.60]), although there was evidence of marked heterogeneity in the estimate (I² = 91%). Among LGBTQ subgroups, transgender people showed the highest risk of PTSD (OR: 2.52 [95% CI: 2.22; 2.87]) followed by bisexual people (OR: 2.44 [95% CI: 1.05; 5.66]), although these comparisons are limited by the lack of data for other sexual and gender minorities, such as intersex people. Interestingly, the risk of PTSD for bisexual people was confirmed also considering lesbian and gay as control group (OR: 1.44 [95% CI: 1.07; 1.93]). The quality of the evidence was low.

CONCLUSIONS

LGBTQ people are at higher risk of PTSD compared with their cisgender/heterosexual peers. This evidence may contribute to the public awareness on LGBTQ mental health needs and suggest supportive strategies as well as preventive interventions (e.g., supportive programs, counselling, and destigmatizing efforts) as parts of a tailored health-care planning aimed to reduce psychiatric morbidity in this at-risk population.

Psychiatric symptoms in Long-COVID patients: a systematic review

Objective

People who have been infected by COVID-19 showing persistent symptoms after 4 weeks from recovery are thought to suffer from Long-COVID syndrome (LC). There is uncertainty on the clinical manifestations of LC. We undertook a systematic review to summarize the available evidence about the main psychiatric manifestations of LC.

Method

PubMed (Medline), Scopus, CINHAL, PsycINFO, and EMBASE were searched until May 2022. Studies reporting estimation of emerging psychiatric symptoms and/or psychiatric diagnoses among adult people with LC were included. Pooled prevalence for each psychiatric condition was calculated in absence of control groups to compare with.

Results

Thirty-three reports were included in the final selection, corresponding to 282,711 participants with LC. After 4 weeks from COVID-19 infection recovery, participants reported the following psychiatric symptoms: depression, anxiety, post-traumatic symptoms (PTS), cognitive and sleeping disturbances (i.e., insomnia or hypersomnia). The most common psychiatric manifestation resulted to be sleep disturbances, followed by depression, PTS, anxiety, and cognitive impairment (i.e., attention and memory deficits). However, some estimates were affected by important outlier effect played by one study. If study weight was not considered, the most reported condition was anxiety.

Conclusions

LC may have non-specific psychiatric manifestations. More research is needed to better define LC and to differentiate it from other post-infectious or post-hospitalization syndromes.

Cell Multi-Bernoulli (Cell-MB) Sensor Control for Multi-Object Search-While-Tracking (SWT)

Information-driven control can be used to develop intelligent sensors that can optimize their measurement value based on environmental feedback. In object tracking applications, sensor actions are chosen based on the expected reduction in uncertainty also known as information gain. Random finite set (RFS) theory provides a formalism for quantifying and estimating information gain in multi-object tracking problems. However, estimating information gain in these applications remains computationally challenging. This paper presents a new tractable approximation of the RFS expected information gain applicable to sensor control for multi-object search and tracking. Unlike existing RFS approaches, the information gain approximation presented in this paper considers the contributions of non-ideal noisy measurements, missed detections, false alarms, and object appearance/disappearance. The effectiveness of the information-driven sensor control is demonstrated through two multi-vehicle search-while-tracking experiments using real video data from remote terrestrial and satellite sensors.

Role of Rituximab Addition to First-line Chemotherapy Regimens in Nodular Lymphocyte-predominant Hodgkin Lymphoma: A Study by Fondazione Italiana Linfomi

Nodular lymphocyte-predominant Hodgkin lymphoma (NLPHL) is a rare entity whose neoplastic cells retain a B-cell phenotype with expression of CD20. Radiotherapy is recommended for favorable stage IA disease while for other stages guidelines suggest therapeutic strategies similar to those used for classic HL. The role of rituximab, although quite widespread, is not completely elucidated. We retrospectively analyzed baseline characteristics of 308 consecutive patients with NLPHL diagnosed in 19 Italian centers from 2000 to 2018. With a median follow-up of 8.4 years (interquartile range: 4.5–12.4) for treated patients, median overall survival (OS) was not reached and estimated 5-year OS was 97.8% and 5-year progression-free survival (PFS) was 84.5%. Five-year cumulative incidence of histological transformation was 1.4%, 95% confidence interval (CI), 0.5%-3.8%. After adjusting for lymphocyte count, splenic involvement, bulky disease and B symptoms (fever, drenching night sweats, unintentional loss >10% of body weight within the preceding 6 months), patients with stage II or more showed superior PFS with immunochemotherapy in comparison to chemotherapy alone (hazard ratio = 0.4, 95% CI, 0.2-0.8; P = 0.015). Our data suggest an advantage of the use of rituximab combined with chemotherapy ± radiotherapy in the treatment of stage II–III–IV NLPHL.

Poor sleep quality may contribute to dysfunctional illness perception, physical and emotional distress in hospitalised patients: results of a national survey of the Italian Society of Consultation-Liaison Psychiatry

Distress associated with physical illness is a well-known risk factor for adverse illness course in general hospitals. Understanding the factors contributing to it should be a priority and among them dysfunctional illness perception and poor sleep quality may contribute to it. As poor sleep quality is recognised as a major risk factor for health problems, we aimed to study its association with illness perception and levels of distress during hospitalisation. This cross-sectional study included a consecutive series of 409 individuals who were hospitalised in medical and surgical units of different hospitals located throughout the Italian national territory and required an assessment for psychopathological conditions. Sleep quality was assessed with the Pittsburgh (Sleep Quality Index), emotional and physical distress with the Edmonton Symptom Assessment System (ESAS), and illness perception with the Brief Illness Perception Questionnaire (BIPQ). Differences between groups, correlations and mediations analyses were computed. Patients with poor sleep quality were more frequently females, with psychiatric comorbidity, with higher scores in the ESAS and BIPQ. Poor sleep quality was related to dysfunctional illness perception, and to both emotional and physical distress. In particular, by affecting cognitive components of illness perception, poor sleep quality may, directly and indirectly, predict high levels of distress during hospitalisation. Poor sleep quality may affect >70% of hospitalised patients and may favour dysfunctional illness perception and emotional/physical distress.Assessing and treating sleep problems in hospitalised patients should be included in the routine of hospitalised patients.

Spleen tyrosine kinase/FMS-like tyrosine kinase-3 inhibition in relapsed/refractory B-cell lymphoma, including diffuse large B-cell lymphoma: updated data with mivavotinib (TAK-659/CB-659)

We report an updated analysis from a phase I study of the spleen tyrosine kinase (SYK) and FMS-like tyrosine kinase 3 inhibitor mivavotinib, presenting data for the overall cohort of lymphoma patients, and the subgroup of patients with diffuse large B-cell lymphoma (DLBCL; including an expanded cohort not included in the initial report). Patients with relapsed/refractory lymphoma for which no standard treatment was available received mivavotinib 60-120 mg once daily in 28-day cycles until disease progression/unacceptable toxicity. A total of 124 patients with lymphoma, including 89 with DLBCL, were enrolled. Overall response rates (ORR) in response-evaluable patients were 45% (43/95) and 38% (26/69), respectively. Median duration of response was 28.1 months overall and not reached in DLBCL responders. In subgroups with DLBCL of germinal center B-cell (GCB) and non-GCB origin, ORR was 28% (11/40) and 58% (7/12), respectively. Median progression free survival was 2.0 and 1.6 months in the lymphoma and DLBCL cohorts, respectively. Grade ≥3 treatment-emergent adverse events occurred in 96% of all lymphoma patients, many of which were limited to asymptomatic laboratory abnormalities; the most common were increased amylase (29%), neutropenia (27%), and hypophosphatemia (26%). These findings support SYK as a potential therapeutic target for the treatment of patients with B-cell lymphomas, including DLBCL. Trial registration: ClinicalTrials.gov number: NCT02000934.

Serum neurofilament levels correlate with electrodiagnostic evidence of axonal loss in paclitaxel-induced peripheral neurotoxicity

INTRODUCTION

Paclitaxel-induced peripheral neurotoxicity (PIPN) typically manifests as a predominantly sensory axonopathy. Nerve conduction studies (NCS) represent the gold standard method to quantify axonal impairment in PIPN. Serum neurofilament light chain (sNfL) levels are emerging biomarkers for quantifying axonal damage in peripheral neuropathies. To date, the association between NCS abnormalities and sNfL levels during paclitaxel-based chemotherapy has not been specifically addressed.

METHODS

We prospectively conducted longitudinal measurement of sNfL levels in 27 chemotherapy-naïve breast cancer patients and correlated conventional NCS recordings with sNfL in 22 of them, before (T0) and after (T1) 12 cycles of weekly paclitaxel-based therapy.

RESULTS

PIPN was diagnosed in 24/27 patients (88%) after completion of the 12-week paclitaxel-based chemotherapy regimen. Serum NfL levels (pg/mL) were significantly higher at T1 compared to T0 (T0: 18.50 ± 12.88 vs T1: 255.80 ± 194.16; p < 0.001). The increase of sNfL levels at T1 significantly correlated with the decrease or abolishment of amplitudes recorded from the sural nerve (r = 0.620; p = 0.0035), sensory radial (r = 0.613; p = 0.005), sensory ulnar (r = 0.630; p = 0.005), and peroneal motor (r = 0.568; p = 0.024) nerves.

CONCLUSION

sNfL levels proportionally increase during chemotherapy administration and significantly correlate with NCS axonal abnormalities in patients with PIPN. A multimodal testing approach employing both sNfL and NCS might improve the PIPN diagnostic accuracy.

Suicide risk in medically ill inpatients referred to consultation-liaison psychiatric services: A multicenter study

BACKGROUND

The aim of this multicenter study was to investigate the suicide risk in medically ill patients admitted to six Italian hospitals for whom a consultation-liaison intervention was requested.

METHODS

Participants completed socio-demographic and clinical report forms and the Brief Illness Perception Questionnaire. Suicidality was assessed using the P4 screener that investigates the presence of Past suicide attempts, Plans to commit a suicide, Probability of completing suicide, and Preventive factors. Participants were categorized as being at no, low or high suicide risk. Univariate and multivariable associations of categorical and continuous variables with suicide risk were investigated using multinomial logistic regression.

RESULTS

Of the 641 inpatients, with mean age 60 years (SD = 16.9) and 49.2 % male, 13.2 % were at high suicidal risk (HR), 7.6 % low risk (LR) and 79.2 % no risk. Contacts with psychiatrists in the previous six months were associated with LR and HR (OR = 2.159 and 2.634, respectively), ongoing benzodiazepine use was associated with a threefold likelihood of LR (OR = 3.005), and the experienced intensity of illness symptoms was associated with LR and HR (OR = 1.257 and OR = 1.248, respectively). CL psychiatrists prescribed appropriate psychotropic drugs and activated liaison interventions and psychological support for the level of suicidal risk.

LIMITATIONS

The use of self-report measures bears the risk of recall bias.

CONCLUSIONS

Our findings based on psychiatric consultations in the general hospital underscore the need to include suicide risk in the routine assessment of inpatients referred to CL psychiatric services and to plan an appropriate management of suicidal risk after discharge.

The effect of ketamine on cognition, anxiety, and social functioning in adults with psychiatric disorders: A systematic review and meta-analysis

Background

It has been shown that ketamine can improve suicidality and depression. Evidence for other dimensions of psychopathology is lacking. We undertook a systematic review to investigate the effect of ketamine on cognition, anxiety, quality of life, and social functioning in adults with psychiatric disorders.

Methods

PubMed (Medline), Scopus, PsycINFO, and EMBASE were searched up to April 2022. Randomized controlled trials (RCTs) on ketamine [or its S (+) enantiomer] reporting data on cognition, anxiety, quality of life, social functioning in adults with psychiatric disorders were included. Standardized mean difference (SMD) was used for summarizing continuous outcomes.

Results

Twenty-two reports were included in the final selection, of which 20, corresponding to 1,298 participants, were included in the quantitative synthesis. Affective disorders were the predominant diagnostic category. Median follow-up time was 21 days. The evidence was rated moderate to very low. In most trials, ketamine was administered intravenously or as adjuvant to electro-convulsant therapy (ECT). Only 2 trials of intranasal esketamine were identified. The effect of ketamine on depression was confirmed (SMD: -0.61 [95% CI: -1.06; -0.16]). Furthermore, by pooling results of 6 RCTs, ketamine may be effective in reducing anxiety symptoms (SMD: -0.42 [95% CI: -0.84; 0.003]), particularly when administered not within ECT (5 trials; SMD: -0.58 [95% CI: -1.07; -0.09]). However, there was moderate heterogeneity of results. Patients treated with ketamine also had an improvement in social functioning (SMD: -0.31 [95% CI: -0.52; -0.10]), although the estimate was based only on 2 studies. No difference to comparators was found with respect to cognition and quality of life.

Conclusion

Alongside the antidepressant effect, ketamine may also improve anxiety and social functioning in adults with affective disorders.

NN-Poly: Approximating common neural networks with Taylor polynomials to imbue dynamical system constraints

Recent advances in deep learning have bolstered our ability to forecast the evolution of dynamical systems, but common neural networks do not adhere to physical laws, critical information that could lead to sounder state predictions. This contribution addresses this concern by proposing a neural network to polynomial (NN-Poly) approximation, a method that furnishes algorithmic guarantees of adhering to physics while retaining state prediction accuracy. To achieve these goals, this article shows how to represent a trained fully connected perceptron, convolution, and recurrent neural networks of various activation functions as Taylor polynomials of arbitrary order. This solution is not only analytic in nature but also least squares optimal. The NN-Poly system identification or state prediction method is evaluated against a single-layer neural network and a polynomial trained on data generated by dynamic systems. Across our test cases, the proposed method maintains minimal root mean-squared state error, requires few parameters to form, and enables model structure for verification and safety. Future work will incorporate safety constraints into state predictions, with this new model structure and test high-dimensional dynamical system data.

A Fast-Tracking-Particle-Inspired Flow-Aided Control Approach for Air Vehicles in Turbulent Flow

Natural phenomena such as insect migration and the thermal soaring of birds in turbulent environments demonstrate animals' abilities to exploit complex flow structures without knowledge of global velocity profiles. Similar energy-harvesting features can be observed in other natural phenomena such as particle transport in turbulent fluids. This paper presents a new feedback control approach inspired by experimental studies on particle transport that have recently illuminated particles' ability to traverse homogeneous turbulence through the so-called fast-tracking effect. While in nature fast tracking is observed only in particles with inertial characteristics that match the flow parameters, the new fast-tracking feedback control approach presented in this paper employs available propulsion and actuation to allow the vehicle to respond to the surrounding flow in the same manner as ideal fast-tracking particles would. The resulting fast-tracking closed-loop controlled vehicle is then able to leverage homogeneous turbulent flow structures, such as sweeping eddies, to reduce travel time and energy consumption. The fast-tracking approach is shown to significantly outperform existing optimal control solutions, such as linear quadratic regulator and bang-bang control, and to be robust to changes in the vehicle characteristics and/or turbulent flow parameters.

Delirium in COVID-19 and post-liver transplant patients: an observational study

OBJECTIVE

Delirium is a major complication in hospitalised patients. This study aimed to compare the mortality trends of patients with delirium according to the underlying physical condition.

METHODS

Hospitalised patients diagnosed with delirium by the Modena Consultation-Liaison Psychiatry Service (Italy) during 2020 were enrolled. Three groups were identified: COVID; after orthotopic liver transplant (OLT); other conditions. The full medical records were screened to retrieve socio-demographic and clinical data. INTERMED score and Delirium Rating Scale were used to retrospectively rate bio-social-complexity and delirium severity. Early (20 days) and end of study (31^st January 2021) mortality were ascertained for each subject.

RESULTS

A total of 103 patients were enrolled. Patients hospitalised for COVID showed higher INTERMED scores (two-tailed t-test, p = 0.019) and higher 20-day mortality (HR = 3.68, p = 0.014). When considering a 1-year follow-up, the main predictor of mortality was patients' age in all three subgroups (HR = 1.06; p = 0.003).

CONCLUSION

Our results suggest that patients hospitalised for COVID-19 with delirium showed higher bio-psycho-social complexity and higher short-term mortality, regardless of the severity of delirium. OLT patients showed lower mortality and bio-psycho-social complexity, despite being still considered as 'complex', according to the INTERMED score. Future research should focus on understanding the underlying mechanisms in the relationship between delirium and mortality.Key pointsPatients hospitalised for COVID-19 with delirium were found at risk of higher short-term mortality and higher bio-psycho-social complexity.OLT patients showed lower overall mortality and lower bio-psycho-social complexity than the other two groups, despite being still in the 'complex' range according to the INTERMED score.Future research should assess the areas of impact of delirium in patients affected by COVID-19, considering short- and long-term outcomes.

Update of the fracture risk prediction tool FRAX: a systematic review of potential cohorts and analysis plan

We describe the collection of cohorts together with the analysis plan for an update of the fracture risk prediction tool FRAX with respect to current and novel risk factors. The resource comprises 2,138,428 participants with a follow-up of approximately 20 million person-years and 116,117 documented incident major osteoporotic fractures.

INTRODUCTION

The availability of the fracture risk assessment tool FRAX® has substantially enhanced the targeting of treatment to those at high risk of fracture with FRAX now incorporated into more than 100 clinical osteoporosis guidelines worldwide. The aim of this study is to determine whether the current algorithms can be further optimised with respect to current and novel risk factors.

METHODS

A computerised literature search was performed in PubMed from inception until May 17, 2019, to identify eligible cohorts for updating the FRAX coefficients. Additionally, we searched the abstracts of conference proceedings of the American Society for Bone and Mineral Research, European Calcified Tissue Society and World Congress of Osteoporosis. Prospective cohort studies with data on baseline clinical risk factors and incident fractures were eligible.

RESULTS

Of the 836 records retrieved, 53 were selected for full-text assessment after screening on title and abstract. Twelve cohorts were deemed eligible and of these, 4 novel cohorts were identified. These cohorts, together with 60 previously identified cohorts, will provide the resource for constructing an updated version of FRAX comprising 2,138,428 participants with a follow-up of approximately 20 million person-years and 116,117 documented incident major osteoporotic fractures. For each known and candidate risk factor, multivariate hazard functions for hip fracture, major osteoporotic fracture and death will be tested using extended Poisson regression. Sex- and/or ethnicity-specific differences in the weights of the risk factors will be investigated. After meta-analyses of the cohort-specific beta coefficients for each risk factor, models comprising 10-year probability of hip and major osteoporotic fracture, with or without femoral neck bone mineral density, will be computed.

CONCLUSIONS

These assembled cohorts and described models will provide the framework for an updated FRAX tool enabling enhanced assessment of fracture risk (PROSPERO (CRD42021227266)).

P14.02.A Serum neurofilaments correlate with axonal loss in paclitaxel-induced peripheral neurotoxicity

Background

Paclitaxel-induced peripheral neuropathy (PIPN) is a dose-limiting axonal polyneuropathy. Nerve conduction studies (NCS) are unique for the assessment of axonal impairment in PIPN. Neurofilaments (NFs), constituent of the neuronal cytoskeleton, are emerging as axonal damage biomarker. To date, the association between changes in NCS and NfL quantification across paclitaxel treatment in breast cancer patients has not been specifically addressed.

MATERIAL AND METHODS: Prospective longitudinal measurement of sNfL levels and NCS in 27 chemotherapy-naïve breast cancer patients before (V0) and after completion (V1) of 12 cycles of weekly paclitaxel-based therapy.

Results

Serum NfL levels (in pg/mL) increased over the course of treatment in the whole of patients (T0: 18,509 +/- 12,886 vs T1:255,805 +/- 194,165, p&lt;0.001). The increase in sNfL levels at T1 showed a significant moderate correlation with the percentage of decrease in the amplitude of the sural (ρ = 0.6205 (p=0.0035), radial (r=0.6134, p=0.005)), ulnar (ρ = 0.6298 (p=0.005)) and peroneal motor (ρ = 0.5676, p=0.024)) nerve in NCS across treatment.

Conclusion

sNfL levels increase proportionally to the degree of paclitaxel-induced neuroaxonal damage, revealing being a promising blood biomarker able to detect the severity of large nerve fiber degeneration and, therefore, improving the diagnostic accuracy in PIPN.

Fast Foveating Cameras for Dense Adaptive Resolution

Traditional cameras field of view (FOV) and resolution predetermine computer vision algorithm performance. These trade-offs decide the range and performance in computer vision algorithms. We present a novel foveating camera whose viewpoint is dynamically modulated by a programmable micro-electromechanical (MEMS) mirror, resulting in a natively high-angular resolution wide-FOV camera capable of densely and simultaneously imaging multiple regions of interest in a scene. We present calibrations, novel MEMS control algorithms, a real-time prototype, and comparisons in remote eye-tracking performance against a traditional smartphone, where high-angular resolution and wide-FOV are necessary, but traditionally unavailable.

Effects of lockdown on emergency room admissions for psychiatric evaluation: an observational study from 4 centres in Italy

Objectives: An observation of the Emergency Room (ER) admissions during the lockdown.Methods: We monitored admissions to the ER requiring psychiatric evaluation during the 2020 lockdown (March 9^th-May 3^rd, 2020) compared to the same period of 2019, in four sites of Northern Italy (ASST Lariana, AUSL Modena, ASU Friuli Centrale and AUSL Romagna). Number of admissions, baseline demographic and clinical variables were extracted from the clinical databases.Results: A 20.0% reduction of psychiatric referrals was observed across the sites (24.2% in ASST Lariana, 30.5% in AUSL Modena, 12.0% in ASU Friuli Centrale and 14.5% in AUSL Romagna). This reduction peaked at 41.5% in the first month of the lockdown. Being homeless as well as with a dual diagnosis (OR 1,67, CI: 1.02-2.74), while living in a residential facility and admission for a depressive episode Being homeless (OR 2.50, CI: 1.36-4.61) and having a dual diagnosis (OR 1,67, CI: 1.02-2.74) were significantly associated with an increase in ER admission, while living in a residential facility (OR 0.48, CI: 0.31-0.74), having a depressive episode (OR 0.36, CI: 0.18-0.73) and a diagnosis of anxiety disorder (OR 0.60, CI: 0.36-0.99) were significantly associated with a decrease.Conclusions: During lockdown, a decrease in psychiatric referrals was observed.

High depression symptomatology and mental pain characterize suicidal psychiatric patients

BACKGROUND

Symptoms of depression are transdiagnostic heterogenous features frequently assessed in psychiatric disorders, that impact the response to first-line treatment and are associated with higher suicide risk. This study assessed whether severe mental pain could characterize a specific phenotype of severely depressed high-risk psychiatric patients. We also aimed to analyze differences in treatments administered.

METHODS

2,297 adult patients (1,404 females and 893 males; mean age = 43.25 years, SD = 15.15) treated in several Italian psychiatric departments. Patients were assessed for psychiatric diagnoses, mental pain, symptoms of depression, hopelessness, and suicide risk.

RESULTS

More than 23% of the patients reported high depression symptomatology and high mental pain (HI DEP/HI PAIN). Compared to patients with lower symptoms of depression, HI DEP/HI PAIN is more frequent among females admitted to an inpatient department and is associated with higher hopelessness and suicide risk. In addition, HI DEP/HI PAIN (compared to both patients with lower symptoms of depression and patients with higher symptoms of depression but lower mental pain) were more frequently diagnosed in patients with personality disorders and had different treatments.

CONCLUSIONS

Patients reporting severe symptoms of depression and high mental pain presented a mixture of particular dangerousness (high trait hopelessness and the presence of suicide ideation with more frequency and less controllability and previous suicide behaviors). The presence of severe mental pain may act synergically in expressing a clinical phenotype that is likewise treated with a more complex therapeutic regime than that administered to those experiencing symptoms of depression without mental pain.

Ventilation strategies to reduce airborne transmission of viruses in classrooms: A systematic review of scientific literature

The recent pandemic due to SARS-CoV-2 has brought to light the need for strategies to mitigate contagion between human beings. Apart from hygiene measures and social distancing, air ventilation highly prevents airborne transmission within enclosed spaces. Among others, educational environments become critical in strategic planning to control the spread of pathogens and viruses amongst the population, mainly in cold conditions. In the event of a virus outbreak - such as COVID or influenza - many school classrooms still lack the means to guarantee secure and healthy environments. The present review examines school contexts that implement air ventilation strategies to reduce the risk of contagion between students. The analysed articles present past experiences that use either natural or mechanical systems assessed through mathematical models, numerical models, or full-scale experiments. For naturally ventilated classrooms, the studies highlight the importance of the architectural design of educational spaces and propose strategies for aeration control such as CO₂-based control and risk-infection control. When it comes to implementing mechanical ventilation in classrooms, different systems with different airflow patterns are assessed based on their ability to remove airborne pathogens considering parameters like the age of air and the generation of airflow streamlines. Moreover, studies report that programmed mechanical ventilation systems can reduce risk-infection during pandemic events. In addition to providing a systematic picture of scientific studies in the field, the findings of this review can be a valuable reference for school administrators and policymakers to implement the best strategies in their classroom settings towards reducing infection risks.

Reduction of Cardiac Fibrosis by Interference With YAP-Dependent Transactivation

BACKGROUND

Conversion of cardiac stromal cells into myofibroblasts is typically associated with hypoxia conditions, metabolic insults, and/or inflammation, all of which are predisposing factors to cardiac fibrosis and heart failure. We hypothesized that this conversion could be also mediated by response of these cells to mechanical cues through activation of the Hippo transcriptional pathway. The objective of the present study was to assess the role of cellular/nuclear straining forces acting in myofibroblast differentiation of cardiac stromal cells under the control of YAP (yes-associated protein) transcription factor and to validate this finding using a pharmacological agent that interferes with the interactions of the YAP/TAZ (transcriptional coactivator with PDZ-binding motif) complex with their cognate transcription factors TEADs (TEA domain transcription factors), under high-strain and profibrotic stimulation.

METHODS

We employed high content imaging, 2-dimensional/3-dimensional culture, atomic force microscopy mapping, and molecular methods to prove the role of cell/nuclear straining in YAP-dependent fibrotic programming in a mouse model of ischemia-dependent cardiac fibrosis and in human-derived primitive cardiac stromal cells. We also tested treatment of cells with Verteporfin, a drug known to prevent the association of the YAP/TAZ complex with their cognate transcription factors TEADs.

RESULTS

Our experiments suggested that pharmacologically targeting the YAP-dependent pathway overrides the profibrotic activation of cardiac stromal cells by mechanical cues in vitro, and that this occurs even in the presence of profibrotic signaling mediated by TGF-β1 (transforming growth factor beta-1). In vivo administration of Verteporfin in mice with permanent cardiac ischemia reduced significantly fibrosis and morphometric remodeling but did not improve cardiac performance.

CONCLUSIONS

Our study indicates that preventing molecular translation of mechanical cues in cardiac stromal cells reduces the impact of cardiac maladaptive remodeling with a positive effect on fibrosis.

O-192 Concomitant autoimmunity in endometriosis-affected women and In Vitro Fertilization (IVF) outcomes: a cohort study

Study question

To evaluate whether the presence of concomitant autoimmunity in endometriosis patients may affect In Vitro Fertilization (IVF)/Intracytoplasmic Injection (ICSI) outcomes.

Summary answer

In ‘normo-responders’ patients autoimmunity did not affected ovarian response to gonadotrophin stimulation yet was the only significant negative predictor of cumulative pregnancy rate (CPR).

What is known already

In the last years, endometriosis has been redefined as a multifactorial disease with a complex pathogenesis. In this setting, a role of both innate and adaptive immune systems have been proposed in endometriosis development. The coexistence of endometriosis and autoimmunity is well-documented. Also, an increased risk of more severe stages of endometriosis in patients with autoimmunity has been recently reported. Even if autoimmunity has been associated with lower pregnancy rates and higher miscarriage rates, whether the presence of autoimmunity in endometriosis patients could act as an additive factor worsening IVF/ICSI response is still not known.

Study design, size, duration

Single-center, retrospective, cohort study. First IVF/ICSI cycles of endometriosis patients with or without autoimmunity carried out from 2007 to 2021 at the Fertility Unit of IRCSS San Raffaele Hospital(Milan) were included. Patients with endometriosis and concomitant autoimmunity were age-matched to endometriosis only controls. Only patients with a complete disease control following endometriosis treatment were admitted to IVF/ICSI. A total of 471 patients were enrolled. The study was conducted according to STROBE guidelines for observational studies.

Participants/materials, setting, methods

Endometriosis diagnosis was surgical/histopathological, yet also ovarian endometriosis at ultrasound assessment by expert operators was included. Autoimmunity was assessed by blood tests for auto-antibodies and/or rheumatological records. Stratified analysis by “expected” ovarian response at baseline according to AFC and/or AMH were performed. Expected ‘poor-responders’ were defined according to Bologna Criteria. The primary outcome was CPR. Secondary outcomes included oocytes retrieved, metaphase II(MII)oocytes and ovarian sensitivity index(OSI), the latter defined as:(number of retrieved oocytes/total gonadotrophin dose)×1000.

Main results and the role of chance

113/471 cases with endometriosis and concomitant autoimmunity and 358/471 age-matched endometriosis only controls were enrolled. The mean age was 35.70±3.75 and 35.95±3.72 (p = 0.543) in cases and controls respectively. No baseline differences in endometriosis disease stage (p = 0.414), surgical treatment for endometriosis prior to IVF (p = 0.617), BMI (p = 0.866) or type of infertility (p = 0.255) were observed when comparing the two groups. In “expected normo-responders”, cases with autoimmunity had significantly higher numbers of oocytes retrieved (p = 0.007), MII oocytes (p = 0.007) and OSI index (p = 0.013) when compared to controls with endometriosis only; the CPR was 12.5% in cases vs. 17.5% in controls, thus comparable between the two groups (p = 0.143). In “expected poor-responders” no significant differences were observed neither in the number of oocytes retrieved and MII oocytes, nor in OSI index; the CPR was 12% in cases with concomitant autoimmunity compared to 7.75% in controls with endometriosis only (p = 0.256). In the generalized linear models (GLMs) of independent predictors associated with CPR, in expected ‘normo-responders’ autoimmunity was the only significant negative predictor of CPR (p = 0.004) whereas in ‘poor-responders’ only age negatively affected CPR (p = 0.001).

Limitations, reasons for caution

This study has a retrospective design. The interpretation of results is based on the validated yet still debated definition of poor-responders according to Bologna Criteria. Results should be interpreted with caution until replicated by future research providing multi-centric and prospective design, larger sample size and more standardized data collection.

Wider implications of the findings

Autoimmunity does not seem to impact neither ovarian reserve nor ovarian response to gonadotropin, as it may act a ‘competitive’ rather than ‘additive’ risk factor for infertility in endometriosis. However, in ‘normo-responders’ autoimmunity seems to reduce the chances of pregnancy following IVF/ICSI perhaps impairing endometrial receptivity and embryo implantation.

Trial registration number

Due to the retrospective design of the study, full IRB approval at the institution was not needed.

The Relationship Between Mental Pain, Suicide Risk, and Childhood Traumatic Experiences: Results From a Multicenter Study

Objective: Mental pain and exposure to maltreatment are significant risk factors for suicidal behavior. This study aimed to investigate whether mental pain could be associated with a recent suicide attempt and whether it could mediate the relationship between childhood traumatic experiences and suicide risk in psychiatric patients. Methods: A multicenter observational study was organized as a joint project with representatives of numerous mixed Italian academic and clinical settings. Between December 2017 and March 2020, batteries of tests were administered to patients, assessing suicidal ideation and behavior, mental pain (usual and worst mental pain in the past 15 days), depression, and childhood maltreatment. Results: A total of 2,137 psychiatric patients (1,313 women and 824 men) were included in the final sample, and 315 reported having attempted suicide in the last 3 months. Suicide attempters (compared to nonattempters) had higher odds of reporting worse mental pain (odds ratios [ORs] between 1.02 and 1.17; P < .001) and suicidal intent with/without a specific plan (ORs between 11.57 and 11.77; P < .001). They also had higher odds of having a personality disorder (borderline personality disorder: ORs between 2.65 and 3.01; P < .001; other personality disorders: ORs between 1.96 and 2.28; P < .01) and major depression (ORs between 1.62 and 1.70; P < .05). Childhood trauma was associated with suicide risk directly (standardized effects between 0.06 and 0.07; P < .01) and indirectly through mental pain (usual mental pain: standardized indirect effect = 0.11, P < .001; worst mental pain in the past 15 days: standardized indirect effect = 0.12, P < .001). Conclusions: Mental pain constitutes a crucial framework for assessing the individual need for psychiatric help. Assessing mental pain allows identification of the main ingredient of suicide risk and puts the clinician in a strategic position to unlock some motives behind the wish to die. Further research is needed to learn if childhood adversities may interact with adult mental pain and thus foster suicide risk.

A Holistic Approach for Role Inference and Action Anticipation in Human Teams

The ability to anticipate human actions is critical to many cyber-physical systems, such as robots and autonomous vehicles. Computer vision and sensing algorithms to date have focused on extracting and predicting visual features that are explicit in the scene, such as color, appearance, actions, positions, and velocities, using video and physical measurements, such as object depth and motion. Human actions, however, are intrinsically influenced and motivated by many implicit factors such as context, human roles and interactions, past experience, and inner goals or intentions. For example, in a sport team, the team strategy, player role, and dynamic circumstances driven by the behavior of the opponents, all influence the actions of each player. This paper proposes a holistic framework for incorporating visual features, as well as hidden information, such as social roles, and domain knowledge. The approach, relying on a novel dynamic Markov random field (DMRF) model, infers the instantaneous team strategy and, subsequently, the players’ roles that are temporally evolving throughout the game. The results from the DMRF inference stage are then integrated with instantaneous visual features, such as individual actions and position, in order to perform holistic action anticipation using a multi-layer perceptron (MLP). The approach is demonstrated on the team sport of volleyball, by first training the DMRF and MLP offline with past videos, and, then, by applying them to new volleyball videos online. These results show that the method is able to infer the players’ roles with an average accuracy of 86.99%, and anticipate future actions over a sequence of up to 46 frames with an average accuracy of 80.50%. Additionally, the method predicts the onset and duration of each action achieving a mean relative error of 14.57% and 15.67%, respectively.

MO106: Circulating Neutrophil Count is Associated with Severity of Chronic Kidney Disease

BACKGROUND AND AIMS

Neutrophils (Ns) play a key role in inflammation and tissue injury, in particular in acute renal failure, by releasing a complex of cytotoxic products such as reactive oxygen intermediates, enzymes and microbicidal polypeptides. These effects are prevented or mitigated by Ns depletion [1, 2]. Here we investigated the relationships between Ns count and the severity of kidney dysfunction in patients with chronic kidney disease (CKD).

METHOD

In this cross-sectional study we evaluated the association between circulating Ns absolute number, CKD stage and measured glomerular filtration rate (mGFR) in 393 patients with renal disease from different causes. CKD stage was established on the basis of mGFR and K/DOQI guidelines [3]. The relationships of Ns count and other considered covariates with mGFR were evaluated by uni- and multi-variable linear regression models (Table 1). Variables considered in univariable models are listed in Table 1. Variables included in multivariable models were identified with forward selection. Circulating Ns were measured by Coulter LH 780 Hematology Analyzer (Beckman Coulter, Milan, Italy). The GFR was measured by the iohexol plasma clearance technique, a gold standard for direct GFR measurement [4]. P &lt; .05 was considered as statistically significant.

RESULTS

The mean ± SD age and mGFR of the patients were 54.64 ± 13.75 years and 62.75 ± 22.52 mL/min/1.73 m2 (range: 15.53–131.79 mL/min/1.73 m2), respectively. Most patients had a kidney function in stage 2 and 3a (Figure 1A). The absolute number of Ns averaged 4.32 ± 1.77 × 103µL−1. Ns counts increased progressively in parallel with increasing CKD stage (P &lt; .005, Figure 1A) and were negatively correlated with mGFR (P &lt; .001, Figure 1B). At multivariable analysis, mGFR was associated negatively with Ns count and positively with basophils (Bs) count (Table 1).

CONCLUSION

In patients with CKD higher numbers of Ns and lower numbers of Bs, even within the normal range, were independently associated with more severe renal insufficiency. A major limitation of the study is the cross-sectional design that does not allow to establish a causal relationship between Ns count and severity of kidney dysfunction. These data provide the basis for studies to investigate mechanisms explaining these associations.

The impact of trauma, substance abuse, and psychiatric illness on suicidal and self-harm behaviours in a cohort of migrant detainees: An observational, prospective study

BACKGROUND

According to the WHO, detainees attempt suicide ten times more than the general population.

AIMS

To investigate the impact of migration trauma on Suicidal and Self-Harm Behaviours (SSHB) of migrants in jail and to explore how substance use and other psychiatric features affect this relationship.

METHODS

Prospective cohort study, conducted at the 'Sant'Anna' jail in Modena (Italy) between February 2017 and September 2019. Socio-demographic, psychiatric features and records of previous SSHB were collected. Experience of migration-related trauma was assessed with the LiMEs (List of Migration Experiences) checklist. Participants were followed-up for the occurrence of further SSHB. Survival analysis was performed and Cox's Hazard Ratios (HR) were used as a measure of association of comparisons.

RESULTS

Amongst the 112 subjects (96% male, median age 33), the prevalence of any mental disorder was 26% and of substance abuse 59%. History of SSHB was present in 36% of the sample. Median follow-up time was 80 days. During follow-up, 11 events were observed (of which three were suicide attempts). Cumulative survival probability was 85%. Having experienced trauma related to war and violence was significantly associated with SSHB, HR: 7.05. No SSHB were recorded amongst subjects without substance abuse.

CONCLUSIONS

Migrants in custody who experienced trauma in the post-migration period, attempt SSHB seven times more frequently than those without traumas at any time. War trauma and post-migration trauma due to exposure to violence seem to be more strongly associated with SSHB, also controlling for psychiatric diagnosis, ongoing psychopharmacological therapy and substance abuse. Further research and possible intervention programs should focus on addressing post-migration living-difficulties.

The Effect of the Use of Hearing Aids in Elders: Perspectives

Older adults with hearing loss have difficulties during conversation with others because an elevated auditory threshold reduces speech intelligibility, especially in noisy environments. Listening and comprehension often become exhausting tasks for hearing-impaired elders, resulting in social isolation and depression. The aim of the present study was to investigate the advantages of hearing aid use in relation to relief from listening-related fatigue, which is still controversial. Participants included a sample of 49 hearing-impaired elders affected by presbycusis for whom hearing aids were prescribed. The Modified Fatigue Impact Scale was used to assess cognitive, physical and psychosocial fatigue. The vitality subscale of the Short Form Health Survey 36 and a single item of the multi-dimensional Speech, Spatial and Quality Hearing Scale (“Do you have to put a lot of effort to hear what is being said in conversation with others?”) were also used. The Cognitive Failures Questionnaire was used to investigate daily errors related to lack of memory and reduced mindedness. Hearing aids rehabilitation resulted in improved speech intelligibility in competing noise, and a significant reduction in cognitive and psychosocial fatigue and listening effort in conversation. Vitality was also improved and a significant reduction in the Cognitive Failures Questionnaire scores was observed. Findings from the study indicate that the use of hearing aids in older impaired-listeners provide them not only with an increased auditory function but also with a reduction in listening-related fatigue and mindedness.

Glomerular resistances predict long-term GFR decline in type 2 diabetic patients without overt nephropathy: a longitudinal subgroup analysis of the DEMAND trial

AIMS

Investigating whether and to what extent changes in glomerular hemodynamic parameters, beyond glomerular hyperfiltration, could predict glomerular filtration rate (GFR) decline in hypertensive, non-proteinuric type 2 diabetic patients.

MATERIALS AND METHODS

We estimated baseline afferent (Ra) and efferent (Re) arteriolar resistances and glomerular hydrostatic pressure in 60 consecutive patients from DEMAND study, using the Gomez' equations. Baseline renal plasma flow was measured by para-aminohippurate plasma clearance, and GFR was measured by iohexol plasma clearance at baseline and every 6 months for a median of 4.0 years [IQR 3.5-4.0 years]. Patients with a GFR decline > or ≤ 3 mL/min/1.73 m²/year were categorized as "Progressors" and "Non-progressors," respectively. Predictors of GFR decline were studied by univariable and multivariable logistic regression analysis.

RESULTS

•The GFR declined by a median [IQR] of 4.06 [5.46-2.00] mL/min/1.73 m²/year in the study group as a whole and by 5.35 [6.60-4.48] mL/min/1.73 m²/year and 1.71 [2.14-1.33] mL/min/1.73 m²/year in Progressors and Non-progressors, considered separately. Progressors had a higher baseline Ra (3487.3 ± 1349.3 dyne•sec•cm^-5 vs. 2877.0 ± 668.9 dyne•sec•cm^-5, p < 0.05) and higher Ra/Re ratio (1.4 ± 0.5 vs. 1.1 ± 0.3, p < 0.01) than Non-progressors. At multivariable logistic regression analysis, Ra/Re ratio and arterial hypertension duration were independently associated with GFR decline (odds ratio [95% CI] 8.50 [1.56-46.28] and 1.14 [1.01-1.28]), respectively.

CONCLUSIONS

Increased Ra/Re ratio and arterial hypertension duration predict early GFR decline in hypertensive non-proteinuric type 2 diabetic patients. These findings could be explained by glomerular hypoperfusion and chronic ischemic injury related to pre-glomerular arteriolar narrowing.

The lesson learned from the new c.2547-1G>T mutation combined with p.R854Q:when a type 2N mutation reveals a quantitative von Willebrand factor defect

Type 2N is a rare von Willebrand disease (VWD) variant involving an impairment in the FVIII carrier function of von Willebrand factor (VWF). It has a phenotype that mimics hemophilia A, and FVIII binding to VWF (VWF:FVIIIB) is tested to differentiate between the two disorders. Type 2N VWF defects may also be associated with quantitative VWF mutations (type 2N/type 1), further complicating the identification of cases. We report on a new quantitative VWF mutation (c.2547-1G>T) revealed by a p.R854Q type 2N mutation acting as homozygous despite being carried as a heterozygous defect. The proband had near-normal VWF levels (initially ruling out a defective VWF synthesis) and slightly reduced FVIII levels, while a VWF:FVIIIB test showed significantly reduced binding. Routine tests on type 2N homozygotes or heterozygotes combined with quantitative VWF defects in our cohort showed reduced FVIII levels in both groups, but it was only in the former that the FVIII/VWF:Ag ratio was always significantly reduced. The two tests are therefore not enough to identify all forms of type 2N VWD. While relatives of type 2N homozygotes usually have normal FVIII levels and FVIII/VWF:Ag ratios, relatives of type 2N/type 1 may have high FVIII/VWF:Ag ratios, but their VWF:FVIIIB and/or VWF:FVIIIB/VWF:Ag ratios are always low. Measuring FVIII and VWF levels may therefore suggest type 2N VWD in patients carrying type 2N mutations alone, but not in type 2N combined with quantitative VWF defects. The VWF:FVIIIB test should consequently always be included when exploring VWF function, whatever VWD patient’s phenotype.

The Complex Interplay of Inflammation, Metabolism, Epigenetics, and Sex in Calcific Disease of the Aortic Valve

Calcification of the aortic valve is one of the most rapidly increasing pathologies in the aging population worldwide. Traditionally associated to cardiovascular risk conditions, this pathology is still relatively unaddressed on a molecular/cellular standpoint and there are no available treatments to retard its progression unless valve substitution. In this review, we will describe some of the most involved inflammatory players, the metabolic changes that may be responsible of epigenetic modifications and the gender-related differences in the onset of the disease. A better understanding of these aspects and their integration into a unique pathophysiology context is relevant to improve current therapies and patients management.

Advanced competence in intensive care unit: expectations, role ambiguity between physicians and nurses in intensive care units. Multi - method survey

BACKGROUND AND AIM

The roles of physicians and nurses have undergone profound changes in recent years, becoming more complex and creating, at times, overlapping competencies with consequent negative repercussions in terms of problems related to autonomy and inter-professional collaboration. The study aims to detect the opinions of intensive care physicians and nurses with respect to their skills and role expectations.

METHOD

The study was conducted in two phases. In the first phase, with a qualitative design, data were collected through the focus group. In the second phase, with quantitative design, an ad hoc questionnaire was constructed from the results of the previous phase.   Results: 3 main themes emerged from the focus groups: the need to increase the system of inter-professional collaboration; autonomy and professional role; and the need for a shared advanced training system for physicians and nurses. The results of the questionnaire show that both professionals believe that the development of advanced skills does not lead to conflicting situations and role ambiguity unless the skills are recognized and respected. Both professionals agree that it is useful and necessary to implement a shared educational pathway.   Conclusion: Inter-professional collaboration, specialist skills and specific training are a key element of the ICU teamwork.

Peer support between healthcare workers in hospital and out-of-hospital settings: a scoping review

BACKGROUND AND AIM

The healthcare workers, mostly in emergency departments, are exposed to emotionally strong situations that can lead to psychological trauma. Often those who experience the "second victim" phenomenon find comfort in dealing with Peers that can help to understand emotions and normalize lived experiences. A scoping review was conducted to clarify the key concepts available in the literature and understand Peer Support characteristics and methods of implementation.  Methods. Scoping review J.B.I. approach was used. The reviewers analyzed the last twenty-one years of literature and extracted data from relevant studies.  Results. The research revealed 49 articles that discuss Peer Support in the healthcare system. Often articles involve healthcare workers without work area and role distinctions. 56% of the articles have been published in the last two years and the Anglo-Saxon countries are the main geographical area of ​​origin (82%). Peer support emerges as a preclinical psychological support for people involved in tiring situations. It's based on mutual respect and on voluntary and not prejudicial help. Peers are trained to guide the support relationship and identify the signs of possible pathologies. Peer Support can be proposed as one to one/group peer support, or through online platforms.  Conclusion. It can be said that Peer Support programs had an important development in the years of the Covid 19 pandemic. Many of the studies affirm that the personnel involved have benefited from the programs available. It is necessary to carry out further research to determine the pre and post intervention benefits.

Gender differences in Anxious-depressive symptomatology, Metabolic Syndrome and Colorectal Adenomas among outpatients undergoing colonoscopy: a cross-sectional study according to a PNEI perspective

BACKGROUND AND AIM OF THE WORK

To explore gender differences in patients suffering from anxious-depressive symptoms, Metabolic Syndrome (MetS) and Colorectal Adenomas (CRAs) in a sample of outpatients undergoing colonoscopy for screening purposes.

METHODS

Cross-sectional study. 126 consecutive outpatients of both sexes undergoing colonoscopy for non-specific abdominal symptoms between January 2015 and June 2021 at the Modena Policlinico General Hospital (Modena, Northern Italy) were enrolled. MetS was diagnosed according to ATPIII and IDF criteria. Anxiety and depression were assessed with the Hospital Anxiety and Depression Scale (HADS), while the Temperament and Character Inventory (TCI) was used to study personality. The SF-36 was also included as a measure of quality of life perception.

RESULTS

Among 126 outpatients (51.60% male) undergoing colonoscopy, 51 (44%) had CRAs, 54 (47%) MetS, 41 (41.40%) anxiety symptoms, 22 (22.20%) depressive symptoms and 13 (13.10%) combined anxious-depressive symptoms. HADS-Anxiety (t=2.68, p=0.01) and TCI Reward Dependence (TCI-RD) (t=3.01, p=0.00) mean scores were significantly higher in women; conversely, SF-36 Mental Component Summary scores were higher in men. CRAs were significantly prevalent in men (χ2=9.32, p=0.00) and were statistically significantly associated with male sex at the univariate logistic regression analysis (OR=3.27; p<0.01). At the multivariate logistic regression, diastolic hypertension (p<0.01) was positively associated with male sex, while TCI-RD (p=0.04) and HDL hypocholesterolemia (p=0.02) were inversely associated with male sex.

CONCLUSIONS

Several significant gender differences in anxious-depressive symptoms, MetS and CRAs were found. These preliminary data suggest the need to consider gender specificities while implementing therapeutic, diagnostic, and preventive strategies.

Mid-term psychiatric consequences of the COVID-19 pandemic: a 4 months observational study on emergency room admissions for psychiatric evaluation after the (first) lockdown period in Italy

PURPOSE

The aim of our study is to evaluate the number and the features of admissions to the emergency room (ER) requiring psychiatric consultation, in the period between May 4th and August 31st 2020.

METHODS

We carried out a retrospective longitudinal observational study examining the 4 months following the initial lockdown imposed during the COVID-19 outbreak (May 4th and August 31st 2020). More specifically, the ER admissions leading to psychiatric referral were reviewed at all seven public hospitals of AUSL Romagna (Emilia Romagna region, Italy). Socio-demographic variables, history of medical comorbidities or psychiatric disorders, reason for ER admission, psychiatric diagnosis at discharge, and actions taken by the psychiatrist were collected.

RESULTS

An 11.3% (p = 0.007) increase in psychiatric assessments was observed when compared with the same period of the previous year (2019). A positive personal history of psychiatric disorders (OR:0.68, CI: 0.53-0.87) and assessments leading to no indication for follow-up (OR: 0.22, CI: 0.13-0.39) were significantly less frequent, while there was a significant increase of cases featuring organic comorbidities (OR: 1.24, CI: 1.00-1.52) and suicidal ideation/self-harm/suicide attempt (OR: 1,71, CI: 1.19-2.45) or psychomotor agitation (OR: 1.46, CI: 1.02-2.07) as reason for admission.

CONCLUSIONS

Our results showed an increase in ER psychiatric consultations compared to the previous year, underlying the increased psychological distress caused by the lockdown.
