Ruptured Sylvian arachnoid cysts: an update on a real problem

PURPOSE

Sylvian arachnoid cysts (SACs) are the most common type of arachnoid cysts and the most prone to undergo a rupture. This event is considered rare but potentially severe. No definite information is available on its occurrence or management. The goal of the present article is to provide an update on the epidemiological, etiological, and clinical aspects and the management of this peculiar clinical condition.

METHODS

A comprehensive review of the English literature of the last 40 years on this topic has been realized. Moreover, a personal series of children investigated and treated in the last 20 years is presented. These patients were managed as follows: (1) treatment of the subdural collection; (2) identification of candidates for surgical treatment of the residual cyst (brain MRI, perfusion brain MRI, prolonged invasive ICP monitoring (selected cases), EEG, neuropsychological tests); (3) surgical treatment of the cyst in the patients with pathological perfusion MRI and/or ICP measurement and/or clear neurophysiological and neuropsychological correlations.

RESULTS

A total of 446 patients (430 from the literature and 16 from the personal series), mainly children, adolescents, and young adults, have been analyzed leading to the following results: (1) SAC rupture is rare but not negligible (yearly risk of rupture: 0.04%; overall risk up to 10% in children affected by SCAs). Prophylactic surgery in asymptomatic cases is not advisable. (2) The mechanism of rupture is not known but an impact of SAC against the sphenoid wing and/or a direct injury on SAC through a thinned temporal bone, with possible laceration of the cyst wall vessels and/or tear of the bridging veins, can be hypothesized. A head injury is often not reported (may be misdiagnosed). (3) Subdural collection (hygroma > chronic hematoma) is the most common finding followed by intracystic bleeding, extradural hematoma, and other types of bleeding. Signs or symptoms of raised intracranial pressure are the most frequent ones. (4) The complication of the rupture is usually treated in emergency or in the acute period by burr hole or craniotomic evacuation of the subdural collection, although a conservative management is possible in some cases. Following the rupture, the majority of SACs are treated (70%), often at the same time of the complication, but no specific investigations are routinely performed to select candidates. According to our protocol, only 43.7% of SACs needed to be treated.

CONCLUSIONS

The "spontaneous" or posttraumatic rupture of SACs is a rare but potentially significant complication followed by a generally good outcome. The course of the cyst is independent from the outcome of the complication, consequently requiring specific investigations for individuating those lesions interfering with CSF dynamics and/or cerebral blood flow.

The Role of Depression on Treatment Adherence in Patients with Heart Failure-a Systematic Review of the Literature

INTRODUCTION

Although poor medication adherence is considered an impacting risk factor for worsening heart failure (HF) outcomes, adherence rates in HF patients continue to be considerably low. To improve this condition, several studies investigated the impact of many determinants on medication adherence; however, few authors explored the role of depression on it.

PURPOSE OF REVIEW

The purpose of this systematic review was to explore the association between depressive symptoms and medication adherence in HF patients. In particular, the research question was is depression a barrier to medication adherence in HF patients?

METHODS

A systematic review of quantitative analysis studies was undertaken. Six electronic databases were searched between the end of October and March 2022. Thirty-one trials were included, all of them assessed depression, adherence to medication, and their possible relationship.

RESULTS

As was intended, findings showed that the impact of a mild to moderate level of depression was significant on adherence to treatment in HF patients. However, many other risk factors emerged, like family support and health practices (es. low sodium diet).

CONCLUSION

The detection of depression in the setting of HF should be crucial to HF patients' physical health and quality of life. Future research should take depression into account, exploring this area through self-report and qualitative interview as well.

Impact of the diagnostic delay of acromegaly on bone health: data from a real life and long term follow-up experience

INTRODUCTION

Acromegaly is a chronic disease with systemic complications. Disease onset is insidious and consequently typically burdened by diagnostic delay. A longer diagnostic delay induces more frequently cardiovascular, respiratory, metabolic, neuropsychiatric and musculoskeletal comorbidities. No data are available on the effect of diagnostic delay on skeletal fragility. We aimed to evaluate the effect of diagnostic delay on the frequency of incident and prevalent of vertebral fractures (i-VFs and p-VFs) in a large cohort of acromegaly patients.

PATIENTS AND METHODS

A longitudinal, retrospective and multicenter study was conducted on 172 acromegaly patients.

RESULTS

Median diagnostic delay and duration of follow-up were respectively 10 years (IQR: 6) and 10 years (IQR: 8). P-VFs were observed in 18.6% and i-VFs occurred in 34.3% of patients. The median estimated diagnostic delay was longer in patients with i-VFs (median: 11 years, IQR: 3), in comparison to those without i-VFs (median: 8 years, IQR: 7; p = 0.02). Age at acromegaly diagnosis and at last follow-up were higher in patients with i-VFs, with respect to those without i-VFs. The age at acromegaly diagnosis was positively associated with the diagnostic delay (p < 0.001, r = 0.216). A longer history of active acromegaly was associated with a high frequency of i-VFs (p = 0.03). The logistic regression confirmed that patients with a diagnostic delay > 10 years had 1.5-folds increased risk of developing i-VFs (OR: 1.5; 95%CI: 1.1-2; p = 0.017).

CONCLUSION

Our data showed that the diagnostic delay in acromegaly has a significant impact on VF risk, further supporting the clinical relevance of an early acromegaly diagnosis.

Enhancing high-fidelity nonlinear solver with reduced order model

We propose the use of reduced order modeling (ROM) to reduce the computational cost and improve the convergence rate of nonlinear solvers of full order models (FOM) for solving partial differential equations. In this study, a novel ROM-assisted approach is developed to improve the computational efficiency of FOM nonlinear solvers by using ROM's prediction as an initial guess. We hypothesize that the nonlinear solver will take fewer steps to the converged solutions with an initial guess that is closer to the real solutions. To evaluate our approach, four physical problems with varying degrees of nonlinearity in flow and mechanics have been tested: Richards' equation of water flow in heterogeneous porous media, a contact problem in a hyperelastic material, two-phase flow in layered porous media, and fracture propagation in a homogeneous material. Overall, our approach maintains the FOM's accuracy while speeding up nonlinear solver by 18-73% (through suitable ROM-assisted FOMs). More importantly, the proximity of ROM's prediction to the solution space leads to the improved convergence of FOMs that would have otherwise diverged with default initial guesses. We demonstrate that the ROM's accuracy can impact the computational efficiency with more accurate ROM solutions, resulting in a better cost reduction. We also illustrate that this approach could be used in many FOM discretizations (e.g., finite volume, finite element, or a combination of those). Since our ROMs are data-driven and non-intrusive, the proposed procedure can easily lend itself to any nonlinear physics-based problem.

Adolescents in the Covid Net: What Impact on their Mental Health?

Given the impact of traumatic events in adolescence and early adulthood, the current Covid 19 pandemic poses a high risk to the well-being and mental health of this population. This study aims to shed light on the traumatic impact of Covid-19 on adolescents and young adults, taking into account their personal experiences, with a particular focus on their emotional regulation skills. From May 2021 to May 2022, 216 adolescents and young adults were surveyed using a series of self-report questionnaires to assess the potentially traumatic effects of Covid-19 and its impact on adolescents' and young adults' emotional regulation skills. Analyses revealed a significant traumatic effect of Covid-19 on the adolescents in our sample. Significant correlations also emerged between the impact of the traumatic event and adolescents' emotional regulation skills. Our findings underscore the importance of considering the psychological impact of Covid-19 on adolescents from both a restorative and preventive perspective.

Patent Licensing and Capacity in a Cournot Model

We consider the problem of patent licensing in a Cournot duopoly in which the innovator (patentee) is one of the firms and it is capacity constrained. We show that when the patentee can produce a relatively small (relatively large) quantity, it prefers licensing by means of a fixed fee (unit royalty). When the patentee can set two-part tariffs in the form of combinations of fixed fees and unit royalties, it charges a positive fixed fee if and only if it is limited to producing a relatively small quantity. We also show that with combinations of fixed fees and royalties, the royalty rate is lower than is true for the standard case.

Faure's new social contract fifty years later: Promises and evolutions

The International Commission on the Development of Education set up by UNESCO in 1971 was chaired by Edgar Faure. The conceptualisation of a new social contract in his work between the 1960s and 1970s had a strong influence on the final report prepared by this commission. Published in 1972, Learning to be: The world of education today and tomorrow is commonly known as the Faure report. Although not explicitly mentioned in the report, the idea of a new social contract provided a political framework for re-establishing the particular relationship between education and society, based on a strong belief in an educational democracy which considered citizens as real agents of change. Fifty years after the publication of the Faure report, another report commissioned by UNESCO, on the Futures of Education, has taken up the idea of the social contract, conceiving it as a means to transform education to harness greater cooperation towards more sustainable futures. However, while the understanding of the social contract elaborated by Faure translated into a clear vision of the emancipatory function of education for the fulfilment of individuals within democratic societies, the political discussion on the relationship among the institutions that should govern the new social contract for education presented in the Futures of Education report appears less explicit. This article discusses the extent to which the principles underpinning the new social contract for education, especially the notion of education as a common good, provide the political framing of a new social contract for education. It examines the relevance of the political discussion of the relationship between education and society elaborated in the Faure report fifty years ago with regard to the formulation of a new social contract for education.

ABCD2, ABCD2-I, and OTTAWA scores for stroke risk assessment: a direct retrospective comparison

Transient ischemic attack (TIA) is a neurologic emergency characterized by cerebral ischemia eliciting a temporary focal neurological deficit. Many clinical prediction scores have been proposed to assess the risk of stroke after TIA; however, studies on their clinical validity and comparisons among them are scarce. The objective is to compare the accuracy of ABCD², ABCD²-I, and OTTAWA scores in the prediction of a stroke at 7, 90 days, and 1 year in patients presenting with TIA. Single-centre, retrospective study including patients with TIA admitted to the Emergency Department of our third-level, University Hospital, between 2018 and 2019. Five hundred three patients were included. Thirty-nine (7.7%) had a stroke within 1 year from the TIA: 9 (1.7%) and 24 (4.7%) within 7 and 90 days, respectively. ABCD², ABCD²-I, and OTTAWA scores were significantly higher in patients who developed a stroke. AUROCs ranged from 0.66 to 0.75, without statistically significant differences at each time-point. Considering the best cut-off of each score, only ABCD² > 3 showed a sensitivity of 100% only in the prediction of stroke within 7 days. Among clinical items of each score, duration of symptoms, previous TIA, hemiparesis, speech disturbance, gait disturbance, previous cerebral ischemic lesions, and known carotid artery disease were independent predictors of stroke. Clinical scores have moderate prognostic accuracy for stroke after TIA. Considering the independent predictors for stroke, our study indicates the need to continue research and prompts the development of new tools on predictive scores for TIA.

Interdialytic weight gain and educational/cognitive, counseling/behavioral and psychological/affective interventions in patients on chronic hemodialysis: a systematic review and meta-analysis

BACKGROUND

This work aimed to shed light on the notorious debate over the role of an educational/cognitive/behavioral or psychological approach in the reduction of interdialytic weight gain (IDWG) in patients on chronic hemodialysis.

METHODS

Searches were run from 1975 to January 2022 on Medline, PubMed, Web of Science, and the Cochrane Library. The search terms included "hemodialysis/haemodialysis" AND "adherence" AND ("fluid intake" OR "water intake") AND ("weight gain" OR "interdialytic weight gain" OR "IDWG") AND "patient-level interventions. Randomized controlled studies were eligible if they were in English, published in a peer-reviewed journal and regarded adults patients with on chronic hemodialysis for at least 6 months; compared educational/cognitive and/or counseling/behavioral or psychological interventions to no intervention on interdialytic weight gain. Outcome of interest was interdialytic weight gain. The review was registered on the International Prospective Register of Systematic Reviews in Health and Social Care (PROSPERO, ID number CRD42022332401).

RESULTS

Eighteen studies (1759 patients) were included in the analysis. Compared to the untreated group, educational/cognitive and/or counseling/behavioral interventions significantly reduced interdialytic weight gain with a pooled mean difference of - 0.15 kg (95% CI - 0.26, 30-0.05; P = 0.004). On the other hand, psychological/affective interventions reduced interdialytic weight gain with a pooled mean difference of - 0.26 kg (95% CI - 0.48, - 0.04; P = 0.020).

CONCLUSIONS

Educational/cognitive, counseling/behavioral or psychological/affective interventions significantly reduced the interdialytic weight gain in patients on chronic hemodialysis, although such reduction did not appear to be clinically relevant on hard outcomes.

Robot-assisted vs laparoscopic lateral transabdominal adrenalectomy: a propensity score matching analysis

BACKGROUND

Laparoscopic adrenalectomy (LA) is the gold standard treatment for adrenal lesions. Robot-assisted adrenalectomy (RAA) is a safe approach, associated with higher costs in absence of clear-cut benefits. Several series reported some advantages of RAA over LA in challenging cases, but definitive conclusions are lacking. We evaluated the cost effectiveness and outcomes of robotic (R-LTA) and laparoscopic (L-LTA) approach for lateral transabdominal adrenalectomy in a high-volume center.

METHODS

Among 356 minimally invasive adrenalectomies (January 2012-August 2021), 286 were performed with a lateral transabdominal approach: 191 L-LTA and 95 R-LTA. The R-LTA and L-LTA patients were matched for lesion side and size, hormone secretion, and BMI with propensity score matching (PSM) analysis. Postoperative complications, operative time (OT), postoperative stay (POS), and costs were compared.

RESULTS

PSM analysis identified 184 patients, 92 in R-LTA and 92 in L-LTA group. The two groups were well matched. The median lesion size was 4 cm in both groups (p = 0.533). Hormonal hypersecretion was detected in 55 and 54 patients of R-LTA and L-LTA group, respectively (p = 1). Median OT was significantly longer in R-LTA group (90.0 vs 65.0 min) (p < 0.001). No conversion was registered. Median POS was similar (4.0 vs 3.0 days in the R-LTA and L-LTA) (p = 0.467). No difference in postoperative complications was found (p = 1). The cost margin analysis showed a positive income for both procedures (3137 vs 3968 € for R-LTA and L-LTA). In the multiple logistic regression analysis, independent risk factors for postoperative complications were hypercortisolism (OR = 3.926, p = 0.049) and OT > 75 min (OR = 8.177, p = 0.048).

CONCLUSIONS

The postoperative outcomes of R-LTA and L-TLA were similar in our experience. Despite the higher cost, RAA appears to be cost effective and economically sustainable in a high-volume center (60 adrenalectomies/year), especially if performed in challenging cases, including patients with large (> 6 cm) and/or functioning tumors.

Profiles of emerging adults' resilience facing the negative impact of COVID-19 across six countries

Although emerging adults (i.e., individuals aged 18-29 years old) may be at a lesser risk of COVID-19 severe illness and mortality, studies have found that the negative impact of COVID-19 on mental health and well-being is higher among emerging adults when compared to other age groups. The current study aimed to identify profile(s) based on resilience resources, which could help emerging adults in managing the disruptions to their lives following the pandemic. A cross-national sample of 1,768 emerging adults from China, Italy, Lithuania, Portugal, Slovenia, and the US was utilized to identify profiles based on different resilience dimensions (ego-resiliency, positivity, religiosity, socioeconomic status, family support, peer support). Results of the Latent Profile Analysis suggest the presence of four different profiles: no resources, only peer, only family, and well-equipped. The association of these profiles with demographic variables, adulthood markers, self-perceived COVID-19 impact, present well-being, and future life perception was investigated. Implications for resilience theory as well as for future interventions are discussed.

Ischemic Cardiomyopathy and Heart Failure After Acute Myocardial Infarction

PURPOSE OF REVIEW

Ischemic cardiomyopathy refers to systolic left ventricular dysfunction in the setting of obstructive coronary artery disease and represents the most common cause of heart failure worldwide. It is often the combination of an irreversible loss of viable mass following an acute myocardial infarction (AMI) with a dysfunctional, but still viable, myocardium in the context of a chronically reduced myocardial blood flow and reduced coronary reserve. Medical treatments aiming at modulating neurohumoral response and restoring blood flow to the ischemic cardiomyocytes were shown to dramatically abate the occurrence of ventricular dysfunction and adverse remodeling in ischemic cardiomyopathy.

RECENT FINDINGS

Novel therapeutic approaches, such as mechanical unloading and modulation of the inflammatory response, appear to be promising. Furthermore, the understanding of the mechanisms by which, despite optimal treatment, heart failure ensues after AMI, with or without adverse remodeling and systolic dysfunction, is a critical step in the search for novel ways to tackle heart failure risk beyond preservation of left ventricular volumes and systolic function. In this review article, we explore the principal pathophysiological mechanisms and pathways of heart failure in ischemic cardiomyopathy, therapeutic opportunities, and knowledge gaps in this area.

Early evaluation of optic nerve head morphology and choroidal thickness after PreserFlo MicroShunt implantation

PURPOSE

The aim of this study is to investigate changes in choroidal and optic nerve morphological parameters following MicroShunt PreserFlo implantation. The secondary aim is to investigate how the structural changes relate to the decrease in intraocular pressure (IOP).

METHODS

Prospective observational study on 15 eyes with glaucoma requiring MicroShunt implantation. Optical coherence tomography was used to measure macular choroidal thickness (MCT), peripapillary choroidal thickness (PCT), lamina cribrosa depth (LCD), cup depth and prelaminar tissue thickness (PLT), before and one day after surgery. Results were expressed in median and interquartile range (IQR) and correlated with IOP results.

RESULTS

The IOP decreased from a median of 25 (IQR = 11) mmHg to 8 (IQR = 2) mmHg the day after surgery. Median MCT increased after MicroShunt implantation from 252.1 (IQR = 156.4) µm to a postoperative value of 318.1 (IQR = 166.6) µm (p < 0.001), with a median increase of + 87.7 µm (+ 26.4%). PCT increased from 157.2 (IQR = 109.1) µm before surgery to 206.0 (IQR = 136.1) µm after surgery (p < 0.001). Moreover, we found a significant post-operative decrease in cup depth (median reduction of - 29.3 µm, p < 0.001) and an increase in PLT (median increase of 27.3 µm, p = 0.028). On the other side, LCD reduction 24 h after surgery didn't reach any statistical significance.

CONCLUSION

PreserFlo implantation determines retinal structural changes which appear similar to those caused by traditional filtering surgery, confirming the effectiveness of this device, meantime carrying a much smaller complications rate when compared to trabeculectomy.

Intramedullary nailing vs modular megaprosthesis in extracapsular metastases of proximal femur: clinical outcomes and complication in a retrospective study

BACKGROUND

Extracapsular proximal femur metastasis could be treated by synthesis or resection and megaprosthesis. No universal accepted guidelines are present in the literature. The aim of our study is to analyze of patients with metastases in the trochanteric region of the femur treated by a single type of intramedullary nailing or hip megaprosthesis.

METHODS

We retrospectively reviewed all patients affected by extracapsular metastases of proximal femur. Anthropometric and anamnestic data, routine blood exams and complications were collected. VAS score and MSTS score was administered before the surgery, ad 1-6-12 months after surgery. An un-paired T test and Chi-square were used. Multiple linear regression and logistic regression was performed. Significance was set for p < 0.05.

RESULT

Twenty patients were assigned in intramedullary Group, twenty-five in megaprostheses Group. The mean operative time is shorter in intramedullary group. Differential shows a higher anemization in megaprostheses group (2 ± 2 vs 3.6 ± 1.3; p = 0.02). The patients of intramedullary group showed malnutrition (Albumin: 30.5 ± 6.5 vs 37.6 ± 6 g/L; p = 0.03) and pro-inflammatory state (NLR: 7.1 ± 6.7 vs 3.8 ± 2.4; p = 0.05) (PLR: 312 ± 203 vs 194 ± 99; p = 0.04) greater than megaprostheses group. The patients in intramedullary groups shows a higher functional performance score than megaprostheses group at 1 month follow-up (MSTS: 16.4 ± 6.3 vs 12.2 ± 3.7; p = 0.004). A multivariate analysis confirms the role of type of surgery (p = 0.001), surgery duration (p = 0.005) and NLR (p = 0.02) in affecting the MSTS. Globally eight complications were recorded, no statistical difference was noticed between the two groups (p = 0.7), no predictor was found at logistic analysis.

CONCLUSION

Intramedullary nailing guarantees a rapid functional recovery, compared to patients undergoing hip megaprosthesis who instead improve gradually over time. The selection of patients with poor prognosis allows the correct surgical indication of nailing, while in the case of a more favorable prognosis, the intervention of hip megaprosthesis is to be preferred.

Cemented vs uncemented megaprostheses in proximal femur metastases: a multicentric comparative study

BACKGROUND

Hip megaprostheses are a long known reconstructive method in the treatment of proximal femur metastases. The use of cemented or uncemented stems is still matter of debate. The aim of this study to compare cemented and uncemented megaprostheses on functional outcomes and complications, in order to establish the role of cementation.

METHODS

We retrospectively analysed 51 metastatic patients with proximal femur metastases treated with endoprosthetic reconstruction by megaprostheses, 25 with cementless stems and 26 with cemented ones with different megaprosthetic implants. The primary endpoint was MSTS score, and the secondary endpoint was to state the incidence of surgical and clinical complications in the two groups. An un-paired T test was used to compare anthropometric, anamnestic data, and MSTS. Chi-square test was performed for evaluation of complication in the two group. Multiple linear regression was used to match the functional outcomes and complications' incidence in the population study. Logistic regression was performed to analyse the odds ratio of different parameters and their role in the incidence of complications.

RESULTS

The mean follow-up was 50.1 months (+ 12.5). In thirty case right side was involved. No statistical differences were noticed between Group A and B regard the age, gender, active fracture/impending fracture. Comparing the MSTS results within the two groups at last follow-up, the score cemented group was higher than cementless one (17.9 + 7.8 vs 24.2 + 5.3; statistical significance p = 0.001). Regarding surgical complications a logistic regression was performed to analyse the odds ratio of age, cementation and length of resection; cementation confirm and odds ratio of 11 times in the incidence of surgical complications.

CONCLUSIONS

Cementation seems to be more liable to complications onset, while improves functional score in metastatic patients compared to uncemented megaprostheses. More studies have to be conducted in order to create a protocol and establish criteria to use cemented or uncemented stems in a frail population like metastatic patients.

Sex and gender differences in migraines: a narrative review

Introduction

Gender medicine is a new medical approach aimed at the study of the differences between women and men in terms of prevention, diagnosis, and the outcome of all diseases. Migraines are among these. They represent the most common neurological illness; they are most prevalent in adults between 20 and 50 years of age and are three to four times more frequent in woman than in men. Affecting people in working age, migraines are a problem that strongly impacts the psychophysical health and productivity of workers, regardless of the specific job task they have.

Methods

A narrative review was performed, searching for the most relevant articles describing gender differences in people suffering from migraines, and particularly in workers.

Results

Migraine global prevalence is 20.7% in women and 9.7% in men whereas prevalence in Italy is 32.9% for women and only 13.0% for men. This difference is partly explained by hormonal differences, as well as by differences in brain structure, genetic polymorphisms and neuronal pathways. Sex differences may also play a role in the progression from episodic to chronic migraine. In workers, migraines are mostly associated with strenuous physical work in men, whilst migraines triggered by night shifts, lack of sleep, or irregular sleep patterns are more common in women.

Conclusions

To this day, the reasons of sex/gender disparity for migraine are still obscure. However, migraines, chronic migraine in particular, have a negative impact on the lives of all individuals affected by this disease, but particularly in women in which family cares and working activity are often superimposed. Migraine prevention strategies should be planned in workers through the occupational health physician.

Children's representations of the COVID-19 lockdown and pandemic through drawings

The COVID-19 pandemic and the measures to face it have placed children and their caregivers in front of many challenges that could represent sources of stress. This work aims to explore the point of view of children through drawing, as a spontaneous means of expression, relating it to parents' perceptions of children's difficulties, strengths, and mentalization skills. The sample consists of 18 children (mean age = 8.22, SD = 1.79). Parents were asked to complete: a socio-demographic questionnaire with information on the impact of COVID-19 on the family, the Strengths and Difficulties Questionnaire, and the Everyday Mindreading Scale. Children were asked to draw three moments: "Before" the pandemic, "During" the lockdown, and "After," when the COVID-19 will be passed. The drawings were coded by constructing a content and expressive analysis grid, adapting coding systems found in the literature. Data were collected at the beginning of the summer of 2020, just after the first lockdown period (from March to May 2020 in Italy). The results of the present work are in line with previous studies that reported experiences of wellbeing and tranquility of children in time spent at home with family during the pandemic. From the drawings emerges that children feel sufficiently able to master the situation, as reflected by including themselves in drawings and providing many details of the house in "During" drawings. The literature also reports a feeling of sadness/loneliness caused by the lack of friends, an element that we also find in the tendency to represent friends significantly more in the drawings concerning the future. Some contents of drawings (inclusion of friends, relatives, and parents) appeared associated with emotional, interpersonal, and mentalizing abilities of children, as perceived by parents. Exploring children's representations of a stressful event like the pandemic through drawings allows to focus both on their difficulties and on their resources, with useful implications for the educational support.

Early and late outcomes of a series of 255 patients with Crohn's disease who underwent resection: 10 years of experience at a single referral center

Patients with Crohn's disease experience an increased risk of postoperative complications and disease recurrence. The aim of this study was to investigate the role of the risk factors in determining these outcomes and whether preoperative removal of some of these risk factors would optimize the results. We conducted a retrospective study analyzing a consecutive series of 255 patients who underwent surgical resection for Crohn's disease between 2010 and 2020. We considered short- and long-term endpoints, such as postoperative complications categorized according to the Clavien–Dindo classification and the appearance of surgical and endoscopic postoperative recurrence. Univariable and multivariable analyses showed that multiple and extensive localizations increased the incidence of postoperative complications (OR = 2.19; 95% CI 1.05–4.5; p = 0.035 and OR = 1.015; 95% CI 1.003–1.028; p = 0.017 for each cm of resected segment, respectively). Regarding theoretically modifiable factors, preoperative hypoalbuminemia (for each g/L reduction) increased the risk of complications with an OR = 1.1; 95% CI 1.02–1.12; p = 0.003. Preoperative steroid therapy exerted a similar effect, with an OR = 2.6; 95% CI 1.1–5.9; p = 0.018. Modifying these last two risk factors by improving the nutritional status or discontinuing steroid therapy significantly reduced complications.

Microscopic positivity of the resection margins was a risk factor for surgical recurrence (OR = 8.7; 95% CI 1.9–40; p = 0.05). Based on the results of the present study, surgeons must examine modifiable risk factors, and careful preoperative tailored management may reduce postoperative complications and disease recurrence.

Financing the cultural and creative industries through crowdfunding: the role of national cultural dimensions and policies

The trend towards digitalisation and technological innovation has reshaped the cultural and creative industries (CCIs) by changing the existing funding models and structures. The aim of this article is to explore the impact of cultural dimensions and policies on the adoption of reward-based crowdfunding as a new form of finance for firms in the CCIs in 12 different European countries during the 2015-2019 period. Our results show that national cultural dimensions and policies significantly affect the demand for cultural and creative crowdfunding. Specifically, the adoption of crowdfunding is broader in individualistic countries and in societies characterised by higher uncertainty avoidance, indulgence, short-term orientation, and lower levels of discrimination between genders. Furthermore, we find that the liberal welfare state model, characterised by limited government interference, market orientation, privatisation and a focus on self-responsibility, and the Southern European welfare model, based on a weak and inefficient state, increase the adoption of crowdfunding in the CCIs. The presence of a central ministry with cultural competence also increases the adoption of crowdfunding in the CCIs. Our findings show a U-shaped relationship between European grants and the demand for crowdfunding, mainly driven by a high or low European involvement within these sectors. We also identify a moderation effect of EU grants on the relationship between cultural dimensions and crowdfunding adoption, suggesting that the magnitude of this relationship depends on the amount of EU grants awarded in a specific country. As a robustness check, we run a set of Poisson regressions with correlated random effects (CREs), confirming our main results.

A 3-Year Single Center Experience With Left Atrial Pressure Remote Monitoring: The Long and Winding Road

Background

Despite continuous advancement in the field, heart failure (HF) remains the leading cause of hospitalization among the elderly and the overall first cause of hospital readmission in developed countries. Implantable hemodynamic monitoring is being tested to anticipate the clinical exacerbation onset, potentially preventing an emergent acute decompensation. To date, only pulmonary artery pressure (PAP) sensor received the approval to be implanted in symptomatic heart failure patients with reduced ejection fraction. However, PAP's indirect estimation of left ventricular filling pressure can be inaccurate in some contexts.

Methods

The VECTOR-HF study (NCT03775161) is examining the safety, usability and performance of the V-LAP system, a latest-generation device capable of continuously monitoring left atrial pressure (LAP). In our center, five advanced HF patients have been enrolled. After confirmation of the transmitted data reliability, LAP trends and waveforms have guided therapy optimization. The aim of this work is to share clinical insights from our center preliminary experience with V-LAP application.

Results

Over a median follow-up time of 18 months, LAP–based therapy optimization managed to reduce intracardiac pressure over time and no hospital readmission occurred. This result was paralleled by an improvement in both functional capacity (6MWT distance 352.5 ± 86.2 meters at baseline to 441.2 ± 125.2 meters at last follow-up) and quality of life indicators (KCCQ overall score 63.82 ± 16.36 vs. 81.92 ± 9.63; clinical score 68.47 ± 19.48 vs. 83.70 ± 15.58).

Conclusion

Preliminary evidence from V-LAP application at our institution support a promising efficacy. However, further study is needed to confirm the technical reliability of the device and to exploit the clinical benefit of left-sided hemodynamic remote monitoring.

Age-Associated Glia Remodeling and Mitochondrial Dysfunction in Neurodegeneration: Antioxidant Supplementation as a Possible Intervention

Aging induces substantial remodeling of glia, including density, morphology, cytokine expression, and phagocytic capacity. Alterations of glial cells, such as hypertrophy of lysosomes, endosomes and peroxisomes, and the progressive accumulation of lipofuscin, lipid droplets, and other debris have also been reported. These abnormalities have been associated with significant declines of microglial processes and reduced ability to survey the surrounding tissue, maintain synapses, and recover from injury. Similarly, aged astrocytes show reduced capacity to support metabolite transportation to neurons. In the setting of reduced glial activity, stressors and/or injury signals can trigger a coordinated action of microglia and astrocytes that may amplify neuroinflammation and contribute to the release of neurotoxic factors. Oxidative stress and proteotoxic aggregates may burst astrocyte-mediated secretion of pro-inflammatory cytokines, thus activating microglia, favoring microgliosis, and ultimately making the brain more susceptible to injury and/or neurodegeneration. Here, we discuss the contribution of microglia and astrocyte oxidative stress to neuroinflammation and neurodegeneration, highlight the pathways that may help gain insights into their molecular mechanisms, and describe the benefits of antioxidant supplementation-based strategies.

Early Life Social Stress Causes Sex- and Region-Dependent Dopaminergic Changes that Are Prevented by Minocycline

Early life stress (ELS) is known to modify trajectories of brain dopaminergic development, but the mechanisms underlying have not been determined. ELS perturbs immune system and microglia reactivity, and inflammation and microglia influence dopaminergic transmission and development. Whether microglia mediate the effects of ELS on dopamine (DA) system development is still unknown. We explored the effects of repeated early social stress on development of the dopaminergic system in male and female mice through histological, electrophysiological, and transcriptomic analyses. Furthermore, we tested whether these effects could be mediated by ELS-induced altered microglia/immune activity through a pharmacological approach. We found that social stress in early life altered DA neurons morphology, reduced dopamine transporter (DAT) and tyrosine hydroxylase expression, and lowered DAT-mediated currents in the ventral tegmental area but not substantia nigra of male mice only. Notably, stress-induced DA alterations were prevented by minocycline, an inhibitor of microglia activation. Transcriptome analysis in the developing male ventral tegmental area revealed that ELS caused downregulation of dopaminergic transmission and alteration in hormonal and peptide signaling pathways. Results from this study offer new insight into the mechanisms of stress response and altered brain dopaminergic maturation after ELS, providing evidence of neuroimmune interaction, sex differences, and regional specificity.

Oropharyngeal Dysphagia After Hospitalization for COVID-19 Disease: Our Screening Results

A high percentage of patients suffered symptoms also after recovery from the Coronavirus Disease-2019 (COVID-19) infection. It is not well clear what are the specific long-term sequelae (complications and symptoms). During the acute phase the patients may develop a multi-organ system pathology including aerodigestive tract. As the pathophysiology of COVID-19 emerges, the aim of our study was to describe the prevalence of oropharyngeal dysphagia after COVID-19 disease. From March to July 2020 we enrolled patients recovered from SARS-CoV-2 infection who had been previously hospitalized for the disease. They were screened for dysphagia by mean of the Eating Assessment Tool-10 (EAT-10). The cases with EAT-10 score > 3 were graded for the aspiration risk by applying the Gugging Swallowing Screen (GUSS) and were submitted to the Swal-QoL questionnaire. The cases with a GUSS score > 19 were subjected to FEES. 8/117 (7%) patients had positive screening result. 4/8 (50%) revealed an abnormal health related quality of life in oropharyngeal dysphagia with a mean Swal-QoL score of 69.73. The most affected domain was the "time of meals" (mean score 65) following by the "sleep" (mean score 66) and "eating desire" (mean score 72). 1/8 cases showed increased risk for aspiration and did not showed endoscopic signs of oropharyngeal dysphagia. Our results showed that the prevalence of upper dysphagia after hospitalization for SARS-CoV-2 is not anecdotal and that probably this long-lasting sequela has a psychogenic etiology.

Heart rate variability and delirium in acute non-cardioembolic stroke: a prospective, cross-sectional, cohort study

OBJECTIVES

Delirium is an acute fluctuating disorder of attention and awareness. It is associated with autonomic dysfunction and increased mortality. The primary endpoint of our study was to measure autonomic activity in acute stroke patients, by means of heart rate variability analysis, in order to identify autonomic modifications that can predispose to delirium.

METHODS

Patients were consecutively enrolled from the stroke unit. Inclusion criteria were age ≥ 18 years and diagnosis of stroke with onset within the previous 72 h confirmed by neuroimaging. Exclusion criteria were atrial fibrillation, congestive heart failure, and conditions requiring intensive care unit. Patients were evaluated by means of Richmond Agitation Sedation Scale (RASS) and Confusion Assessment Method-Intensive Care Unit (CAM-ICU) at baseline, after 72 h, or when symptoms suggesting delirium occurred. For each patient, ECG was recorded at baseline assessment and HRV analysis was conducted on five consecutive minutes of artifact-free ECG traces.

RESULTS

Fifty-six ECGs were available for analysis. During the study period, 11 patients developed delirium. Patients with and without delirium did not differ for sex, age, severity of stroke, and comorbidities. The delirium group had greater standard deviation of the heart rate (DLR - :9.16 ± 8.28; DLR + : 14.36 ± 5.55; p = 0.026) and lower power spectral density of the HF component (DLR - : 38.23 ± 19.23 n.u.; DLR + : 25.75 ± 8.77 n.u.; p = 0.031).

CONCLUSIONS

Acute non-cardioembolic stroke patients with increased variability of heart rate and decreased vagal control are at risk for delirium.

The Hierarchical Contribution of Organic vs. Conventional Farming, Cultivar, and Terroir on Untargeted Metabolomics Phytochemical Profile and Functional Traits of Tomato Fruits

In this work, the impact of terroir, cultivar, seasonality, and farming systems on functional traits of tomato was hierarchically investigated. Untargeted metabolomics, antioxidant capacity, colorimetric assays, and enzyme inhibition were determined. The total phenolic and carotenoid contents significantly varied between growing years, whereas an interaction between the farming system and growing year (p < 0.01) was observed for total phenolics, carotenoids, and flavonoids, and for acetylcholinesterase inhibition. Hierarchical clustering showed that geographical origin and growing year were the major contributors to the differences in phytochemical profiles. Nonetheless, supervised modeling allowed highlighting the effect of the farming system. Several antioxidants (L-ascorbic acid, α-tocopherol, and 7,3',4'-trihydroxyflavone) decreased, whereas the alkaloid emetine and phytoalexin phenolics increased under organic farming. Taken together, our findings indicate that cultivar and pedo-climatic conditions are the main determinants for the functional quality of tomato, whereas the farming system plays a detectable but hierarchically lower.
