Development of a model to predict the risk of early graft failure after adult-to-adult living donor liver transplantation: An ELTR study.

Graft survival is a critical end point in adult-to-adult living donor liver transplantation (ALDLT), where graft procurement endangers the lives of healthy individuals. Therefore, ALDLT must be responsibly performed in the perspective of a positive harm-to-benefit ratio. This study aimed to develop a risk prediction model for early (3 months) graft failure (EGF) following ALDLT. Donor and recipient factors associated with EGF in ALDLT were studied using data from the European Liver Transplant Registry. An artificial neural network classification algorithm was trained on a set of 2073 ALDLTs, validated using cross-validation, tested on an independent random-split sample (n=518), and externally validated on United Network for Organ Sharing Standard Transplant Analysis and Research data. Model performance was assessed using the AUC, calibration plots, and decision curve analysis. Graft type, graft weight, level of hospitalization, and the severity of liver disease were associated with EGF. The model ( http://ldlt.shinyapps.io/eltr_app ) presented AUC values at cross-validation, in the independent test set, and at external validation of 0.69, 0.70, and 0.68, respectively. Model calibration was fair. The decision curve analysis indicated a positive net benefit of the model, with an estimated net reduction of 5-15 EGF per 100 ALDLTs. Estimated risks>40% and<5% had a specificity of 0.96 and sensitivity of 0.99 in predicting and excluding EGF, respectively. The model also stratified long-term graft survival ( p <0.001), which ranged from 87% in the low-risk group to 60% in the high-risk group. In conclusion, based on a panel of donor and recipient variables, an artificial neural network can contribute to decision-making in ALDLT by predicting EGF risk.

Bifidobacteria modulate immune response in pediatric patients with cow's milk protein allergy.

BACKGROUND: In children with an allergy to cow's milk proteins (CMA), the altered composition of intestinal microbiota influences the immune tolerance to milk proteins (CMP). This study aims to investigate the effect of probiotics on the phenotype and activation status of peripheral basophils and lymphocytes in a pediatric CMA cohort. METHODS: CMA children underwent 45 days of treatment with Bifidobacteria. The basophil degranulation and the immune phenotype of B cells, T helper cells, and regulatory T cells were analyzed in peripheral blood at diagnosis (T0), after a 45-day probiotic treatment (T1), and 45 days after the probiotic wash-out (T2). RESULTS: We observed in probiotic-treated CMA patients a decrease in naive T lymphocytes. Among the CD3+ cell subsets, both naive and activated CD4+ cells resulted markedly reduced after taking probiotics, with the lowest percentages at T2. A decreased basophil degranulation was observed in response to all analyzed CMP at T1 compared to T0. CONCLUSIONS: The probiotic treatment resulted in a decrease of circulating naive and activated CD4+ T cells, as well as degranulating basophils. These data suggest that the Bifidobacteria could have a beneficial effect in the modulation of oral tolerance to CMP. TRIAL REGISTRATION: ISRCTN69069358. URL of registration: https://www.isrctn.com/ISRCTN69069358 . IMPACT: Probiotic treatment with Bifidobacteria induces a reduction of both naive and activated circulating CD4+ T cells in pediatric patients with cow's milk allergy (CMA). The probiotic supplementation induces a decreased basophil degranulation. The immunological tolerance persists even after 45 days of the probiotic wash-out. Bifidobacteria in vivo supplementation down-modulates the activation of innate and adaptive immunity in pediatric patients with cow's milk allergy. Bifidobacteria contribute to the development of immune tolerance in CMA patients.

Sharp-Pointed Foreign Body Ingestion in Pediatric Age.

OBJECTIVES: To assess the clinical complications reported after the ingestion of sharp/pointed foreign bodies (FBs) in pediatric age, their incidence among all FB ingestions, and the features and clinical presentation of children. STUDY DESIGN: We have recruited all consecutive patients aged 0-14 years, admitted for sharp/pointed FB ingestion. Clinical data until hospital discharge were accurately recorded, including both children with esophagogastric FB retention who underwent endoscopic removal and children who were radiologically followed-up till spontaneous FB expulsion. Clinical outcomes were recorded for each patient, with special reference to possible prolonged retention and wall perforation during the intestinal passage. RESULTS: We have enrolled 580 children (males/females: 292/288; age range: 11-180 months; mean age ± standard deviation: 50.5 ± 42 months). Sharp/pointed FBs mainly included fragments of metal 270 of 580 (46.55%) and glass 180 of 580 (31%). FBs were endoscopically removed in 79 of 580 (13.6%) children whereas the remaining FBs passed through the gastrointestinal tract over an overall mean time of 29 hours. No cases of intestinal perforation nor prolonged retention were observed. In 3 of 65 (4.6%) procedures the endoscopist faced an uncomfortable endoscopic removal due to the shape and size of the FB which hampered the retrograde passage through the esophageal sphincters. CONCLUSIONS: Our original and extensive data emphasize that accidental ingestion of sharp/pointed FB ingestion is a current issue in pediatric age, especially in toddlers. Metal and glass objects are the most involved FBs and their endoscopic retrieval may not be easy in about 5% of cases. Fortunately, in our pediatric sample no surgical intervention was needed.

Why people were less compliant with public health regulations during the second wave of the Covid-19 outbreak: The role of trust in governmental organizations, future anxiety, fatigue, and Covid-19 risk perception.

Trust in governmental organizations is a crucial factor in terms of encouraging people to conform to public health regulations, such as those recommended to slow down the spread of SARS-CoV-2. However, trust in governmental organizations tends to decline over time, reducing the compliance with public health regulations. This study aimed at exploring, first, the role of future anxiety and fatigue as serial mediators of the relationship between trust in governmental organizations and protective behaviors, and, secondly, the role of Covid-19 risk perception as a moderator between fatigue and protective behaviors. A total of 948 Italian participants (302 males and 646 females), ranged from 18 to 80 years (M = 27.20, SD = 11.01), answered an online survey during the second wave of the Covid-19 outbreak. A moderated serial mediation model was performed using a structural equation modeling. The results indicate that: (1) a higher trust in Italian governmental organizations was associated with a greater compliance in terms of adopting protective behaviors; (2) a lower trust in Italian governmental organizations increased anxiety about the future which, in turn, raised levels of fatigue, leading, finally, to a reduction in the levels of protective behaviors; and (3) as the perceived risk related to Covid-19 increased, the effect of fatigue on protective behaviors decreased. The findings of the current study may provide indications for public health policy on how to increase compliance with the recommended behaviors to be adopted in order to decrease the spread of the SARS-CoV-2.

Health-Related Quality of Life in Pediatric Inflammatory Bowel Disease During COVID-19 Pandemic: A Prospective Study.

OBJECTIVES: The aims of our study were to evaluate health-related quality of life (HRQoL) in children affected by inflammatory bowel disease (IBD) during the first wave of Coronavirus disease 2019 (COVID-19) pandemic and after 12 months. METHODS: This was a single-center, prospective, observational study conducted between April 2020 and April 2021. Children from 10 to 18 years with a confirmed diagnosis of IBD were enrolled during the first COVID-19-related national quarantine. The following information was collected at the baseline and after 12 months: IBD subtype, location and phenotype, disease activity, current and previous therapies. Patients were asked to complete the PROMIS Anxiety and IMPACT III questionnaires. RESULTS: One hundred and eighteen patients were enrolled, of whom 54 (46%) were affected by Crohn disease (CD) and 64 (54%) with ulcerative colitis (UC; median age: 15.5 years, range 10.3-18; M/F: 68/50). Median HRQoL was significantly decreased after 12 months compared with the beginning of COVID-19-related quarantine (T1: 76.7 vs T2: 72.8; P < 0.001). At 12 months, a higher number of children were reported to be in active disease when compared with the enrollment [T2: 22/108 (20.4%) vs T1: 12/118 (10%); P = 0.02]. Multivariate analysis showed a significant influence on HRQoL of quarantine period ( P < 0.001), female sex ( P = 0.016), biologic therapy ( P = 0.011), and active disease ( P < 0.001). CONCLUSIONS: A deterioration of HRQoL after 12 months from COVID-19-related quarantine was observed. Additionally, the higher number of children with active disease at 12 months compared with enrollment may suggest detrimental consequences of the reduced disease control, contributing to decreased HRQoL.

Functional Gastrointestinal Disorders in Mediterranean Countries According to Rome IV Criteria.

OBJECTIVES: The aim of this study was to assess the prevalence of functional gastrointestinal disorders (FGIDs) in children of Mediterranean area using Rome IV criteria and to compare the prevalence of FGIDs using Rome IV and Rome III criteria. METHODS: This was a cross-sectional study enrolling children and adolescents living in Croatia, Greece, Israel, Italy, Macedonia, and Serbia. Subjects were examined in relation to the presence of FGIDs, using the Rome IV criteria. Data were compared with the results of a previous study using Rome III data. RESULTS: We analyzed 1972 children ages 4 to 9 years (group A), and 2450 adolescents 10 to 18 years old (group B). The overall prevalence of FGIDs was 16% in group A and 26% in group B, with statistical differences among countries in both groups (P < 0.001). In group A, the prevalence of FGIDs and of functional constipation (FC) was significantly lower than in the previous study (P < 0.001), whereas in group B no significant difference was found. In both groups of age, the prevalence of abdominal migraine and irritable bowel syndrome decreased significantly (P < 0.001 and P < 0.001, respectively) using Rome IV versus Rome III criteria, conversely functional dyspepsia increased (P < 0.001). CONCLUSIONS: FGIDs are common in children and adolescents, their frequency increases with age, and there is a significant variation in the prevalence of some FGIDs among different European countries. The application of the Rome IV criteria resulted in a significantly lower prevalence of FGIDs in children compared with Rome III criteria.

Laparoscopic gastrectomy for stage II and III advanced gastric cancer: long­term follow­up data from a Western multicenter retrospective study.

INTRODUCTION: There has been an increasing interest for the laparoscopic treatment of early gastric cancer, especially among Eastern surgeons. However, the oncological effectiveness of Laparoscopic Gastrectomy (LG) for Advanced Gastric Cancer (AGC) remains a subject of debate, especially in Western countries where limited reports have been published. The aim of this paper is to retrospectively analyze short- and long-term results of LG for AGC in a real-life Western practice. MATERIALS AND METHODS: All consecutive cases of LG with D2 lymphadenectomy for AGC performed from January 2005 to December 2019 at seven different surgical departments were analyzed retrospectively. The primary outcome was diseases-free survival (DFS). Secondary outcomes were overall survival (OS), number of retrieved lymph nodes, postoperative morbidity and conversion rate. RESULTS: A total of 366 patients with stage II and III AGC underwent either total or subtotal LG. The mean number of harvested lymph nodes was 25 ± 14. The mean hospital stay was 13 ± 10 days and overall postoperative morbidity rate 27.32%, with severe complications (grade ≥ III) accounting for 9.29%. The median follow-up was 36 ± 16 months during which 90 deaths occurred, all due to disease progression. The DFS and OS probability was equal to 0.85 (95% CI 0.81-0.89) and 0.94 (95% CI 0.92-0.97) at 1 year, 0.62 (95% CI 0.55-0.69) and 0.63 (95% CI 0.56-0.71) at 5 years, respectively. CONCLUSION: Our study has led us to conclude that LG for AGC is feasible and safe in the general practice of Western institutions when performed by trained surgeons.

Disc battery ingestion in paediatric age.

AIM: The aim of the present study was to analyse clinical data of children referred for disc battery ingestion in order to assess short- and long-term reported injuries and to identify outcome predictors and trends, define the urgency of intervention and refine treatment guidelines. METHODS: The records of all children admitted to Santobono-Pausilipon Children's Hospital, Naples, Italy for disc battery ingestion from January 2016 to December 2020 were retrospectively reviewed. Odds ratio were computed to assess the association between the different study variables and the rate of complications. RESULTS: We enrolled 118 children. Mild to major complications related to the ingested disc batteries were reported in 12/118 (10.2%) patients. Disc battery oesophageal retention, disc battery diameter >20 mm, together with age below 1 year and symptomatic presentation were the most important factors associated with poor clinical outcome. CONCLUSION: Our data confirm that ingested disc batteries are a serious health hazard and require a timely and qualified medical evaluation. We have identified three predictors of outcome severity: oesophageal retention, large-diameter cells and symptom onset. Disc batteries lodged beyond the oesophagus appear substantially harmless and we may support a more conservative approach.

Hematemesis in Infants: The First Evidence-Based Score to Predict the Need for Timely Endoscopy.

OBJECTIVES: Infantile acute upper gastrointestinal bleeding involves a decision for therapeutic intervention that most pediatricians first coming into contact with the patient are, not unreasonably, unable to objectively provide. Therefore, some objective tools of individual risk assessment would seem to be crucial. The principal aim of the present study was to investigate the anamnestic and clinical parameters of infants with hematemesis, together with laboratory and instrumental findings, to create a scoring system that may help identify those infants requiring an appropriate and timely application of upper gastrointestinal (GI) endoscopy. METHODS: Clinical data of infants admitted for hematemesis to the participating centers over the study period were systematically collected. According to the outcome dealing with rebleeding, need for blood transfusion, mortality, finding of GI bleeding lesions, or need for surgical intervention, patients were blindly divided into a group with major clinical severity and a group with minor clinical severity. Univariate and multivariate logistic regressions were conducted to investigate significant prognostic factors for clinical severity. RESULTS: According to our findings, we drafted a practical diagnostic algorithm and a clinical score able to predict the need for timely upper GI endoscopy (BLOVO infant score). Our clinical scoring system was created by incorporating anamnestic factors, clinical parameters, and laboratory findings that emerged as predictors of a worst outcome. CONCLUSIONS: We provided the first objective tool of individual risk assessment for infants with hematemesis, which could be very useful for pediatricians first coming into contact with the patient in the emergency department.

The Pro12Ala polymorphism of PPARγ2 modulates beta cell function and failure to oral glucose-lowering drugs in patients with type 2 diabetes.

BACKGROUND: We evaluate whether the Pro12Ala polymorphism of peroxisome proliferator-activated receptor γ2 (PPARγ2) has a role in the progression of diabetes by modulating the occurrence of treatment failure to glucose-lowering drugs. METHODS: We studied 215 patients with type 2 diabetes participating in the Thiazolidinediones Or Sulphonylureas and Cardiovascular Accidents Intervention Trial study. All participants were insufficiently controlled (glycated haemoglobin [HbA1c ] 7.0%-9.0%) with metformin 2 g/day and were randomly allocated to add-on pioglitazone or a sulfonylurea. Treatment failure was defined as HbA1c ≥8% on two consecutive visits, 3 months apart. RESULTS: Carriers or non-carriers of the polymorphism had similar age, body mass index, and diabetes duration. Ala carriers had lower fasting plasma insulin, better insulin sensitivity (Homeostasis Model Assessment [HOMA]2-%S), and worse beta cell secretion (HOMA2-%B) than non-carriers. During 24 months of follow-up, 32.5% among the Ala carriers and 8.6% among non-carriers (P < 0.001) developed treatment failure with a cumulative incidence of 18.6 vs 4.6/100 person-years. Those patients who developed treatment failure were older, had a younger age at diabetes diagnosis (48 ± 10 vs 52 ± 7 years; P = 0.032), higher HbA1c (8.1 ± 0.5 vs 7.7 ± 0.5%; P < 0.001), and lower HOMA2-%B (30 ± 12 vs 46 ± 29; P = 0.015) at study entry, as compared to those who did not develop treatment failure. At multivariate analysis, the Pro12Ala polymorphism was significantly associated with treatment failure (hazard ratio [HR] 4.45; 95% confidence interval [CI] 1.79-11.1; P < 0.001); HbA1c at study entry was the other independent predictor of failure in this study population. CONCLUSION: The Pro12Ala polymorphism is associated with a greater insulin sensitivity, reduced beta cell function and a substantially increased risk of treatment failure.

Impact of neoadjuvant therapy followed by laparoscopic radical gastrectomy with D2 lymph node dissection in Western population: A multi-institutional propensity score-matched study.

BACKGROUND AND OBJECTIVES: In the setting of a minimally invasive approach, we aimed to compare short and long-term postoperative outcomes of patients treated with neoadjuvant therapy (NAT) + surgery or upfront surgery in Western population. METHODS: All consecutive patients from six Italian and one Serbian center with locally advanced gastric cancer who had undergone laparoscopic gastrectomy with D2 lymph node dissection were selected between 2005 and 2019. After propensity score-matching, postoperative morbidity and oncologic outcomes were investigated. RESULTS: After matching, 97 patients were allocated in each cohort with a mean age of 69.4 and 70.5 years. The two groups showed no difference in operative details except for a higher conversion rate in the NAT group (p = 0.038). The overall postoperative complications rate significantly differed between NAT + surgery (38.1%) and US (21.6%) group (p = 0.019). NAT was found to be related to a higher risk of postoperative morbidity in patients older than 60 years old (p = 0.013) but not in patients younger (p = 0.620). Conversely, no difference in overall survival (p = 0.41) and disease-free-survival (p = 0.34) was found between groups. CONCLUSIONS: NAT appears to be related to a higher postoperative complication rate and equivalent oncological outcomes when compared with surgery alone. However, poor short-term outcomes are more evident in patients over 60 years old receiving NAT.

A risk-group classification model in patients with bladder cancer under neoadjuvant cisplatin-based combination chemotherapy.

The objective of the current research was to explore the potential prognostic value of readily available clinical and pathologic variables in bladder cancer. The novel association found between cholesterol levels and prognosis may provide the rationale for exploring novel treatments. Patients included had histologically confirmed urothelial bladder cancer and were treated with at least 3 cycles of cisplatin-based neoadjuvant chemotherapy before radical cystectomy with lymphadenectomy. A total of 245 patients at low, intermediate and high risk, presenting with 0-1, 2 or 3-4 risk factors, including positive lymph nodes, Hb <12.8, NLR ≥2.7 and cholesterol levels ≥199, were included. Five-year cancer-specific survival rate was 0.67, 0.78 and 0.94 at high, intermediate and low risk, respectively. Total cholesterol levels at the time of cystectomy may represent a commonly assessable prognostic factor and may be incorporated in a clinically meaningful risk-group classification model.

Lay abstract This present study assessed a large group of patients with urothelial bladder cancer treated with chemotherapy followed by radical cystectomy, to capture the predictive power of commonly collected clinical, pathological and biochemical factors. The design of the study highlighted that higher cholesterol levels at the time of cystectomy were associated with shorter cancer-specific survival. This finding suggests that high blood-cholesterol levels truly have a negative influence on surviving cancer. In conclusion, total cholesterol levels at the time of cystectomy may represent a commonly assessable prognostic factor and could be incorporated into a clinically meaningful and valuable risk-group classification model.

Do isolates from pharyngeal and rectal swabs match blood culture bacterial pathogens in septic VLBW infants? A pilot, cross-sectional study.

Serial body site swabbing is used to monitor horizontal spread of aggressive bacterial species in the neonatal intensive care unit (NICU). Since colonization/carriage is thought to precede systemic infection, one might expect to retrieve colonizing pathogens from blood cultures. This hypothesis, however, has not been fully investigated in very low birth weight (VLBW) infants that are at high sepsis' risk. The primary outcome was, in a population of VLBW infants with late-onset sepsis, the matching between blood culture results and pathogens isolated from rectal and nose/pharyngeal surveillance swabs in the preceding 2 weeks. The secondary outcomes were the site of swabbing and time interval from colonization to blood culture positivity. Out of 333 VLBW neonates, 80 (24%) were diagnosed with bacterial sepsis. In 46 (57%) neonates, the blood culture showed the same pathogen species cultured from a swab. Of these, 30 were isolated from infants with both body sites colonized with an average time interval of 3.5 days; 2/16 were isolated from rectal swabs and 14 /16 from nose/pharyngeal samples.Conclusion: Our data show a fair correspondence between bacteria colonizing the nasopharynx and/or the rectum and pathogens later isolated from blood cultures. This association depends on the swabbing site, number of sites, and pathogen species. Although these data constitute valuable results, they are not sufficient for providing the sole base of a thoughtful clinical decision. What is Known: • Body site's colonization may precede systemic infection. • Little is known on this mechanism in VLBW infants that are at higher sepsis' risk. What is New: •Colonizing bacteria partially correspond to pathogens of blood cultures in VLBW infants with sepsis. • Correspondence depends on swabbing site, number of sites, and pathogen species.

The role of cognitive and non-cognitive factors in dental anxiety: A mediation model.

Dental anxiety is a crucial problem for dentistry because it may represent a significant risk to oral health. Different factors, whether non-cognitive (e.g., traumatic dental events) or cognitive (e.g., the patient's subjective perceptions), may cause dental anxiety. However, previous studies have assessed these factors as independent predictors of dental anxiety, without providing any exploration of potential mediational pathways. The current study assessed the role of certain cognitive dimensions (i.e., the dentist's perceived professionalism and communicational attitudes, and the patient's perceived lack of control) as mediators between traumatic dental events and dental anxiety. The sample comprised 253 patients who had accessed a public university hospital dental surgery. The mediation analysis used a structural equation modeling. Traumatic dental events were positively associated with dental anxiety but, among the cognitive factors, only lack of control was. Furthermore, lack of control mediated the relationship between traumatic dental events and dental anxiety, although this mediation was only partial. This study sheds light on the mechanisms through which non-cognitive and cognitive factors may affect dental anxiety. The clinical implications for dental practice, in terms of improving the psychological well-being of patients, are discussed.

Optical coherence tomography angiography findings in Huntington's disease.

OBJECTIVES: To evaluate the retinal and choriocapillaris vascular networks in macular region and the central choroidal thickness (CCT) in patients affected by Huntington disease (HD), using optical coherence tomography angiography (OCTA) and enhanced depth imaging spectral-domain OCT (EDI SD-OCT). METHODS: We assessed the vessel density (VD) in superficial capillary plexus (SCP), deep capillary plexus (DCP), and choriocapillaris (CC) using OCTA, while CCT was measured by EDI SD-OCT. RESULTS: Sixteen HD patients (32 eyes) and thirteen healthy controls (26 eyes) were enrolled in this prospective study. No significant difference in retinal and choriocapillaris VD was found between HD patients and controls while CCT turned to be thinner in patients respect to controls. There were no significant relationships between OCTA findings and neurological parameters. CONCLUSION: The changes in choroidal structure provide useful information regarding the possible neurovascular involvement in the physiopathology of HD. Choroidal vascular network could be a useful parameter to evaluate the vascular impairment that occurs in this neurodegenerative disease.

Comparative analysis of density histograms and visual scores in incremental and volumetric high-resolution computed tomography of the chest in idiopathic pulmonary fibrosis patients.

BACKGROUND: Volumetric high-resolution computed tomography (HRCT) of the chest has recently replaced incremental CT in the diagnostic workup of idiopathic pulmonary fibrosis (IPF). Concomitantly, visual and quantitative scores have been proposed for disease extent assessment to ameliorate disease management. PURPOSE: To compare the performance of density histograms (mean lung attenuation, skewness, and kurtosis) and visual scores, along with lung function correlations, in IPF patients submitted to incremental or volumetric thorax HRCT. MATERIAL AND METHODS: Clinical data and CT scans of 89 newly diagnosed and therapy-naive IPF patients were retrospectively evaluated. RESULTS: Forty-six incremental and 43 volumetric CT scans were reviewed. No differences of density histograms and visual scores estimates were found by comparing two HRCT techniques, with an optimal inter-operator agreement (concordance correlation coefficient >0.90 in all instances). Single-breath diffusing lung capacity for carbon monoxide (DLCOsb) was inversely related with the Best score (r = -00.416; p = 0.014), the Kazerooni fibrosis extent (r = -0.481; p = 0.004) and the mean lung attenuation (r = -0.382; p = 0.026), while a positive correlation was observed with skewness (r = 0.583; p = 0.001) and kurtosis (r = 0.543; p = 0.001) in the incremental HRCT sub-group. Similarly, in the volumetric CT sub-cohort, DLCOsb was significantly associated with skewness (r = 0.581; p = 0.007) and kurtosis (r = 0.549; p = 0.018). Correlations with visual scores were not confirmed. Forced vital capacity significantly related to all density indices independently on HRCT technique. CONCLUSIONS: Density histograms and visual scores similarly perform in incremental and volumetric HRCT. Density quantification displays an optimal reproducibility and proves to be superior to visual scoring as more strongly correlated with lung function.

Flavor identification inversely correlates with body mass index (BMI).

BACKGROUND AND AIMS: Dietary choices are influenced by several factors including physiological, social, or genetic factors. Among these, flavor is the most important determinant modulating food preferences. The aim of the present study was to assess flavor identification abilities in patients with obesity (Ob) in comparison with matched normal weight (NW) and over-weight (OW) subjects using a specific and validated chemosensory test. METHODS AND RESULTS: The flavor test was administered to 140 Ob patients recruited in the obesity outpatient Unit at the Federico II University hospital and to the same number of NW and OW subjects matched by sex, age, and smoking habit. Flavor score (FS) inversely correlated with BMI. Median [Q1; Q3] FS was significantly higher in NW (14.5 [12; 16]) than in Ob (13 [10; 15] p < 0.001) and not significantly different from OW (14 [12; 16]) individuals. FS was also higher in OW than in Ob subjects (p < 0.005). When separated according to age quartiles, the BMI-related differences in FS were still significant in younger quartiles, while they were abolished in the older. CONCLUSIONS: BMI is a critical factor modulating flavor identification, particularly in young subjects. Further investigations are needed to explore the precise mechanism and the causal relationship between body weight and olfactory dysfunctions. CLINICALTRIAL ID: NCT03506074.

Mentalizing stigma: Reflective functioning as a protective factor against depression and anxiety in transgender and gender-nonconforming people.

OBJECTIVE: The current study examined the role of internalized transphobia (IT) as a mediator between gender-related rejection and mental health, and reflective functioning (or mentalization) as a resilience factor moderating the relationship between both rejection and IT with mental health. METHOD: This online study included 203 Italian transgender and gender-nonconforming (TGNC) individuals ranged in age from 18 to 66 years old (M = 30.70; standard deviation = 10.79). Moderated-mediation analysis was performed using a structural equation modeling approach. RESULTS: Both rejection and IT were positively associated with mental health, and IT mediated the relationship between rejection and mental health. Mentalization moderated the relationship between rejection and IT with mental health. The indirect effect of rejection on mental health through IT was moderated by mentalization. CONCLUSIONS: Findings highlight psychological paths that may inform individual- and group-level mentalization-based interventions to reduce minority stress in TGNC individuals.

Supratotal Resection of Glioblastoma: Is Less More?

BACKGROUND: A relationship between the extent of resection (EOR) and survival has been demonstrated in patients with glioblastomas (GBMs). However, despite gross total resection (GTR) of the enhancing nodule (EN), GBMs usually relapse, generally near the surgical cavity. OBJECTIVE: The aim of this study was to determine the prognostic role of FLAIR resection of GBMs by analyzing pre- and post-operative MRIs to estimate the EOR of EN, FLAIR-hyperintense regions and total tumor volume (TTV). METHODS: Radiologic and clinical outcomes were analyzed retrospectively. Pre- and post-operative EN volume, pre- and postoperative FLAIR volume (POFV), and pre- and postoperative TTV were analyzed. EOR was then calculated for each component. Time-dependent ROC curves and cut-off values for pre- and post-operative volumes and EOR were calculated. A Kaplan-Meier analysis with the log-rank test and Cox regression analysis were then used to analyze progression-free survival (PFS) and overall survival (OS). RESULTS: We did not find any correlation between EOR of FLAIR-altered regions and patient survival. On the other hand, there were statistically significant relationships between the prognosis and both a preoperative EN volume less than 31.35 cm3 (p=0.032) and a postoperative EN volume less than 0.57 cm3 (p=0.015). Moreover, an EOR of EN greater than 96% was significantly associated with the prognosis (p=0.0051 for OS and p=0.022 for PFS). CONCLUSION: Our retrospective, multi-center study suggests that survival in patients with GBM is not affected by the extent of resection of FLAIR-hyperintense areas.
