Insight into the Relationship Between Motor and Cognitive Symptoms in Essential Tremor.

Essential tremor (ET) is a heterogeneous disorder characterized by bilateral upper limbs action tremor and, possibly, neurological signs of uncertain significance, including voluntary movement abnormalities and cognitive disturbances, i.e., the so-called 'soft' signs configuring the ET-plus definition. While motor and cognitive disturbances often coexist in ET, their interrelationship remains largely unexplored. Here we aim to further investigate the relationship between motor symptoms, objectively assessed through kinematic analysis, and cognitive dysfunctions in ET. Seventy ET patients underwent clinical examination, as well as kinematic recordings of tremor and finger tapping and a thorough cognitive assessment. We then tested clinic-demographic and kinematic differences between patients with and without cognitive abnormalities, i.e., with mild cognitive impairment (MCI). Correlation analysis served to explore potential associations between kinematic and cognitive data. Forty-three ET patients (61.42%) had MCI. ET-MCI patients exhibited reduced movement velocity during finger tapping compared to those with normal cognition (p < 0.001). Lower movement velocity during finger tapping was associated with poorer cognitive performance. Namely, we observed a correlation between movement velocity and performance on the Babcock Story Immediate and Delayed Recall Test (r = 0.52 and r = 0.45, both p < 0.001), as well as the interference memory task at 10 and 30 s (r = 0.3, p = 0.008 and r = 0.2, p = 0.03). In this study, we have provided data for a better pathophysiological interpretation of motor and cognitive signs in ET, including the role played by the cerebellum or extra-cerebellar areas, which possibly underpin both signs.

Targeted next-generation sequencing analysis in Italian patients with keratoconus.

OBJECTIVE: To report variants in 26 candidate genes and describe the clinical features of Italian patients with keratoconus (KC). SUBJECTS/METHODS: Sixty-four patients with a confirmed diagnosis of KC were enrolled in this genetic association study. Patients were classified into two study groups according to whether they had a confirmed diagnosis of progressive or stable KC. A purpose-developed Next Generation Sequencing (NGS) panel was used to identify and analyse the coding exons and flanking exon/intron boundaries of 26 genes known to be associated with KC and corneal dystrophies. Interpretation of the pathogenic significance of variants was performed using in silico predictive algorithms. RESULT: The targeted NGS research identified a total of 167 allelic variants of 22 genes in the study population; twenty-four patients had stable keratoconus (n. 54 variants) and forty patients had progressive disease (n. 113 variants). We identified genetic variants of certain pathogenic significance in five patients with progressive KC; in addition, eight novel genetic variants were found in eight patients with progressive KC. Mutations of FLG, LOXHD1, ZNF469, and DOCK9 genes were twice more frequently identified in patients with progressive than stable disease. Filaggrin gene variants were found in 49 patients (76% of total), of whom 32 patients (80% of progressive KC group) had progressive disease. CONCLUSIONS: Targeted NGS research provided new insights into the causative effect of candidate genes in the clinical phenotype of keratoconus. Filaggrin mutations were found to represent a genetic risk factor for development of progressive disease in Italy.

Estimated prevalence of keratoconus in the largest metropolitan area of Italy.

PURPOSE: To estimate the prevalence of keratoconus in a population of subjects undergoing first eye examination in an eye clinic in Italy. METHODS: A single-center, cross-sectional, study was conducted involving patients who underwent first eye examination at an eye clinic in Rome between September 2021 and June 2022. The prevalence of keratoconus was determined by Placido-disk corneal topography using the maximum keratometry (Kmax) value and the Cone Magnitude and Location Index (CLMI) for keratoconus screening. Subjective analysis was performed by two experienced corneal specialists, who classified the outcome into two groups: normal and keratoconus. Risk factors, including family history of keratoconus, allergy or atopy, thyroid disease, eye rubbing habit and gender were also examined. RESULTS: A total of 512 subjects between 7 and 81 years old were evaluated. The inter-observer agreement to classify subjects in normal or keratoconus group was excellent (k = 1.0); the estimated prevalence in the specific population was 2.1%. Presence of positive family history (9% of keratoconus vs 5% normal), concomitant allergy or atopy (27% vs 9%) and eye rubbing habit (18% vs 4%) were associated with a higher risk of disease. CONCLUSION: This study reported a high estimated prevalence of keratoconus in a metropolitan area of Italy, as found in recent studies in the Mediterranean and Middle East countries. Screening for keratoconus is highly recommendable and easily feasible with corneal topography under expert supervision and may be indicated primarily in young population to improve early detection and prompt therapeutic management for halting disease progression.

Extracorporeal Membrane Oxygenation After Liver Transplant in Children: A Review of the ELSO Registry.

There are minimal data describing use of extracorporeal membrane oxygenation (ECMO) in pediatric patient after a liver transplantation (LT). This study aimed at describing ECMO run in this specific situation using the data from Extracorporeal Life Support Organization (ELSO) Registry between January 1, 2010, to December 31, 2022. We described patients' characteristics at ECMO initiation, outcome and mortality risk factors. We identified 27 patients with a median age of 2.7 years (interquartile range (IQR) = 1.5-9.9). Main indication for ECMO support was respiratory (14/27 [52%]) followed by extracorporeal cardiopulmonary resuscitation (ECPR) (7/27 [26%]) and cardiac (6/27 [22%]). Overall in-hospital mortality was 63% (17/27). Mortality rate according to ECMO indications was 50% for both respiratory and cardiac failure and reached 100% for ECPR patients. Overall, nonsurvivors experienced significantly more complications under ECMO support (p = 0.007). Main on-ECMO complications were hemorrhagic (11/27 [41%]) and thrombotic (7/27 [26%]). No clinical or biologic factors was predictive of patients' outcome. Our results suggest that ECMO support is a viable option for cardiac and respiratory indications after pediatric LT. Occurrence of complications while on ECMO are associated with unfavorable outcomes. The extremely high mortality rate in ECPR patients merits further research.

Accuracy of an Air-Puff Dynamic Tonometry Biomarker to Discriminate the Corneal Biomechanical Response in Patients With Keratoconus.

PURPOSE: The aim of this study was to assess accuracy of the mean corneal stiffness ( kc , N/m) parameter to discriminate between patients with keratoconus and age-matched healthy subjects. METHODS: Dynamic Scheimpflug imaging tonometry was performed with Corvis ST (Oculus Optikgeräte GmbH, Germany) in patients with keratoconus (n = 24; study group) and age-matched healthy subjects (n = 32; control). An image processing algorithm was developed to analyze the video sequence of the Corvis ST air-puff event and to determine the geometric and temporal parameters that correlated with the corneal tissue biomechanical properties. A modified 3-element viscoelastic model was used to derive the kc parameter, which represented the corneal tissue resistance to deformation under load. Receiver operating characteristic curves were used to assess the overall diagnostic performance for determining the area under the curve, sensitivity, and specificity of the kc in assessing the corneal tissue deformation to the Corvis ST air-puff event in keratoconus and control eyes. The Corvis Biomechanical Index ( CBI ) was analyzed for external validation. RESULTS: The kc parameter was significantly different between keratoconus and controls ( P < 0.001), ranging from 24.9 ±3.0 to 34.2 ±3.5 N/m, respectively. It was highly correlated with CBI (r = -0.69; P < 0.001); however, the kc parameter had greater specificity (94%) than CBI (75%), whereas the 2 biomarkers had similar area under the curve (0.98 vs. 0.94) and sensitivity (96% vs. 92%) in predicting the occurrence of keratoconus. CONCLUSIONS: The kc parameter extracted by video processing analysis of dynamic Scheimpflug tonometry data was highly accurate in discriminating patients with clinically manifest keratoconus compared with controls.

Heart failure 'the cancer of the heart': the prognostic role of the HLM score.

AIMS: The multi-systemic effects of heart failure (HF) resemble the spread observed during cancer. We propose a new score, named HLM, analogous to the TNM classification used in oncology, to assess the prognosis of HF. HLM refers to H: heart damage, L: lung involvement, and M: systemic multiorgan involvement. The aim was to compare the HLM score to the conventional New York Heart Association (NYHA) classification, American College of Cardiology/American Heart Association (ACC/AHA) stages, and left ventricular ejection fraction (LVEF), to assess the most accurate prognostic tool for HF patients. METHODS AND RESULTS: We performed a multicentre, observational, prospective study of consecutive patients admitted for HF. Heart, lung, and other organ function parameters were collected. Each patient was classified according to the HLM score, NYHA classification, ACC/AHA stages, and LVEF assessed by transthoracic echocardiography. The follow-up period was 12 months. The primary endpoint was a composite of all-cause death and rehospitalization due to HF. A total of 1720 patients who completed the 12 month follow-up period have been enrolled in the study. 520 (30.2%) patients experienced the composite endpoint of all-cause death and rehospitalization due to HF. 540 (31.4%) patients were female. The mean age of the study population was 70.5 ± 12.9. The mean LVEF at admission was 42.5 ± 13%. Regarding the population distribution across the spectrum of HLM score stages, 373 (21.7%) patients were included in the HLM-1, 507 (29.5%) in the HLM-2, 587 (34.1%) in the HLM-3, and 253 (14.7%) in the HLM-4. HLM was the most accurate score to predict the primary endpoint at 12 months. The area under the receiver operating characteristic curve (AUC) was greater for the HLM score compared with the NYHA classification, ACC/AHA stages, or LVEF, regarding the composite endpoint (HLM = 0.645; NYHA = 0.580; ACC/AHA = 0.589; LVEF = 0.572). The AUC of the HLM score was significantly better compared with the LVEF (P = 0.002), ACC/AHA (P = 0.029), and NYHA (P = 0.009) AUC. CONCLUSIONS: The HLM score has a greater prognostic power compared with the NYHA classification, ACC/AHA stages, and LVEF assessed by transthoracic echocardiography in terms of the composite endpoint of all-cause death and rehospitalization due to HF at 12 months of follow-up.

CHA2DS2-VASc score as a predictor of clinical outcomes in hospitalized patients with and without chronic kidney disease.

BACKGROUND: High CHA2DS2-VASc score (Congestive heart failure, Hypertension, Age > 75 years, Diabetes mellitus, prior Stroke or transient ischemic attack or thromboembolism, Vascular disease, Age 65-74 and Sex category) was associated with adverse clinical outcomes in different settings. The aim of the present study was to evaluate the association between CHA2DS2-VASc score and R2CHA2DS2-VASc score (which includes renal impairment) with in-hospital mortality and length of hospital stay in patients hospitalized in an internal medicine ward. METHODS: We enrolled 983 consecutive patients admitted during 3 years in an internal medicine ward. R2CHA2DS2-VASc score was calculated by adding 2 points to CHA2DS2-VASc for the presence of chronic kidney disease (CKD), defined according to K-DOQI. The primary outcome was a composite of all-cause mortality and length of hospital stay > 10 days. RESULTS: Patients with CKD stages 3-5 presented with increased CHA2DS2-VASc vs stages 1-2 (p < 0.001). The composite outcome occurred in 47.3% of inpatients. Multivariable linear logistic regression analyses adjusted for presence of infectious diseases and cancer, with the occurrence of composite outcome showed an adjusted OR of 1.349 (95% CI 1.248-1.462) and 1.254 (95% CI 1.179-1.336) for CHA2DS2-VASc and R2CHA2DS2-VASc scores, respectively. No differences were found in the association between CHA2DS2-VASc and R2CHA2DS2-VASc scores with the composite outcome (AUC 0.631 vs 0.630), and furthermore, adding the presence/absence of infectious diseases during hospitalization and positive cancer history to the models increased the AUC (0.667 and 0.663). CONCLUSIONS: Incrementally higher CHA2DS2-VASc score is associated with increased length of hospital stay and mortality in patients hospitalized in an internal medicine ward, regardless of the presence of CKD.

May Bradykinesia Features Aid in Distinguishing Parkinson's Disease, Essential Tremor, And Healthy Elderly Individuals?

BACKGROUND: Bradykinesia is the hallmark feature of Parkinson's disease (PD); however, it can manifest in other conditions, including essential tremor (ET), and in healthy elderly individuals. OBJECTIVE: Here we assessed whether bradykinesia features aid in distinguishing PD, ET, and healthy elderly individuals. METHODS: We conducted simultaneous video and kinematic recordings of finger tapping in 44 PD patients, 69 ET patients, and 77 healthy elderly individuals. Videos were evaluated blindly by expert neurologists. Kinematic recordings were blindly analyzed. We calculated the inter-raters agreement and compared data among groups. Density plots assessed the overlapping in the distribution of kinematic data. Regression analyses and receiver operating characteristic curves determined how the kinematics influenced the likelihood of belonging to a clinical score category and diagnostic group. RESULTS: The inter-rater agreement was fair (Fleiss K = 0.32). Rater found the highest clinical scores in PD, and higher scores in ET than healthy elderly individuals (p < 0.001). In regard to kinematic analysis, the groups showed variations in movement velocity, with PD presenting the slowest values and ET displaying less velocity than healthy elderly individuals (all ps < 0.001). Additionally, PD patients showed irregular rhythm and sequence effect. However, kinematic data significantly overlapped. Regression analyses showed that kinematic analysis had high specificity in differentiating between PD and healthy elderly individuals. Nonetheless, accuracy decreased when evaluating subjects with intermediate kinematic values, i.e., ET patients. CONCLUSION: Despite a considerable degree of overlap, bradykinesia features vary to some extent in PD, ET, and healthy elderly individuals. Our findings have implications for defining bradykinesia and categorizing patients.

GLIM-diagnosed malnutrition predicts mortality and risk of hospitalization in systemic sclerosis: A retrospective study.

BACKGROUND: Malnutrition is a well-known risk factor for morbidity and mortality in many clinical settings and only few studies assessed the role of malnutrition on systemic sclerosis (SSc) patients' outcomes. The aim of this retrospective study was to evaluate the role of malnutrition as a predictive risk factor for mortality and/or hospitalization in SSc patients during a 4-year follow-up. METHODS: One hundred and one SSc patients were included in the study. Biochemical analyses, disease activity index, disease severity scale and anthropometric data were recorded at enrollment. Malnutrition was assessed by the Global Leadership Initiative on Malnutrition (GLIM) criteria. RESULTS: Malnutrition according to GLIM criteria was found in 22 patients (21.8%). During a 4-year follow-up, 20 (19.8%) SSc patients died or were hospitalized for all causes and 11 of them (55.0%) were malnourished. Kaplan-Meier curves showed that event free-survival for composite end-point of mortality and risk of hospitalization was significantly shorter in malnourished than in non-malnourished patients (p<0.001). The survival probability at 4 years was 0.885 (95% CI=0.818-0.959) in the non-malnourished group and 0.500 (95% CI=0.329-0.759) in the malnourished group (p<0.001). In multivariate analysis, malnutrition [HR=4.380 (95% CI=1.706-11.243), p = 0.002] was the most significant predictive risk factor for the composite end-point. Also, female gender [HR=0.157 (95% CI=0.055-0.449), p<0.001], age [HR=1.0450 (95% CI=1.011-1.090), p = 0.012] and disease severity scale [HR=1.269 (95% CI=1.089-1.479), p = 0.002] were predictive factors for the composite end-point. CONCLUSIONS: Malnutrition according to GLIM criteria represents a significant predictive risk factor for composite end-point of mortality and risk of hospitalization in SSc patients.

Use of Remdesivir in Patients with SARS-CoV-2 Pneumonia in a Real-Life Setting during the Second and Third COVID-19 Epidemic Waves.

In this retrospective comparative study, we evaluated the effectiveness of remdesivir (RDSV) in patients with SARS-CoV-2 pneumonia. Individuals hospitalized between March 2020 and August 2022 at S.M. Goretti Hospital, Latina, with a positive test for SARS-CoV-2 and, concomitantly, pneumonia, were included. The overall survival was the primary endpoint. The composite secondary endpoint included death or progression in severe ARDS at 40 days. The study population was stratified according to treatment into two groups: the RDSV group (patients treated with RDSV-based regimens) and the no-RDSV group (patients treated with any other, not RDSV-based, regimens). Factors associated with death and progression to severe ARDS or death were assessed by multivariable analysis. A total of 1153 patients (632 belonging to the RDSV group and 521 to the no-RDSV group) were studied. The groups were comparable in terms of sex, PaO2/FiO2 at admission, and duration of symptoms before hospitalization. Further, 54 patients (8.5%) in the RDSV group and 113 (21.7%) in the no-RDSV group (p < 0.001) died. RDSV was associated with a significantly reduced hazard ratio (HR) of death (HR, 0.69 [95% CI, 0.49-0.97]; p = 0.03), compared to the no-RDSV group, as well as a significantly reduced OR of progression in severe ARDS or death (OR, 0.70 [95% CI 0.49-0.98]; p = 0.04). An overall significantly higher survival rate was observed in the RDSV group (p < 0.001, by log-rank test). These findings reinforce the survival benefit of RDSV and support its routine clinical use for the treatment of COVID-19 patients.

Effectiveness, Tolerability and Prescribing Choice of Antiviral Molecules Molnupiravir, Remdesivir and Nirmatrelvir/r: A Real-World Comparison in the First Ten Months of Use.

In 2022, three antiviral drugs-molnupiravir, remdesivir and nirmatrelvir/ritonavir-were introduced for treatment of mild-to-moderate COVID-19 in high-risk patients. The aim of this study is the evaluation of their effectiveness and tolerability in a real-life setting. A single-center observational study was set up, with the involvement of 1118 patients, with complete follow-up data, treated between the 5th of January and the 3rd of October 2022 at Santa Maria Goretti's hospital in Latina, Central Italy. A univariable and a multivariable analysis were performed on clinical and demographic data and composite outcome, the persistence of symptoms at 30 days and time to negativization, respectively. The three antivirals showed a similar effectiveness in containing the progression of the infection to severe COVID-19 and a good tolerability in the absence of serious adverse effects. Persistence of symptoms after 30 days was more common in females than males and less common in patients treated with molnupiravir and nirmatrelvir/r. The availability of different antiviral molecules is a strong tool and, if correctly prescribed, they can have a significant role in changing the natural history of infection for frail persons, in which vaccination could be not sufficient for the prevention of severe COVID-19.

A randomized clinical trial assessing theranostic-guided corneal cross-linking for treating keratoconus: the ARGO protocol.

The Assessment of theranostic guided riboflavin/UV-A corneal cross-linking for treatment of keratoconus (ARGO; registration number NCT05457647) clinical trial tests the hypothesis that theranostic-guided riboflavin/UV-A corneal cross-linking (CXL) can provide predictable clinical efficacy for halting keratoconus progression, regardless of treatment protocol, i.e., either with or without epithelial removal. Theranostics is an emerging therapeutic paradigm of personalized and precision medicine that enables real-time monitoring of image-guided therapy. In this trial, the theranostic software module of a novel UV-A medical device will be validated in order to confirm its accuracy in estimating corneal cross-linking efficacy in real time. During CXL procedure, the theranostic UV-A medical device will provide the operator with an imaging biomarker, i.e., the theranostic score, which is calculated by non-invasive measurement of corneal riboflavin concentration and its UV-A light mediated photo-degradation. ARGO is a randomized multicenter clinical trial in patients aged between 18 and 40 years with progressive keratoconus aiming to validate the theranostic score by assessing the change of the maximum keratometry point value at 1-year postoperatively. A total of 50 participants will be stratified with allocation ratio 1:1 using a computer-generated stratification plan with blocks in two treatment protocols, such as epithelium-off or epithelium-on CXL. Following treatment, participants will be monitored for 12 months. Assessment of safety and performance of theranostic-guided corneal cross-linking treatment modality will be determined objectively by corneal tomography, corneal endothelial microscopy, visual acuity testing and slit-lamp eye examination.

Phase angle, nutritional status, and mortality in systemic sclerosis: An exploratory pilot study.

OBJECTIVES: Systemic sclerosis (SSc) is a rare autoimmune disease characterized by microvascular damage and fibrosis of the skin and internal organs. Among SSc complications, changes in nutritional status have a negative effect on quality of life and predispose patients to malnutrition. The aim of this exploratory pilot study was to examine whether bioelectrical impedance analysis-derived phase angle (PhA) is a parameter of nutritional status and a marker of mortality in patients with SSc. METHODS: Consecutive adult patients with SSc were included in the study. Biochemical analyses, anthropometric data, and bioelectrical impedance analysis assessments were recorded at the time of enrollment. The Malnutrition Universal Screening Tool (MUST) and Global Leadership Initiative on Malnutrition (GLIM) were applied to assess nutritional status. RESULTS: A total of 104 patients with SSc (88 women; median age: 55 y [interquartile range (IQR), 45.5- 66 y]) were enrolled. In patients with SSc and high malnutrition risk according to MUST, mean values of PhA were significantly lower than those of patients with SSc and low malnutrition risk (4° [IQR, 3.7°-4.4°] vs 4.6° [IQR, 4.2°-5.1°]; P = 0.004). Patients with SSc and malnutrition according to the GLIM criteria showed significantly lower PhA than patients with SSc but without malnutrition (3.8° [IQR, 3.5°-4.3°] vs 4.6° [IQR, 4.2°-5.1°]; P < 0.0001). Kaplan-Meier curves demonstrated that overall survival was significantly shorter (34.57 mo [±13.35] vs 48 mo [±0]; P = 0.001) in patients with SSc and PhA <3.75°. In the multivariate analysis, only PhA was a predictive factor for death (hazard ratio: 0.283; 95% confidence interval, 0.083-0.965; P = 0.044). CONCLUSIONS: The data obtained suggest that lower PhA values in patients with SSc are associated with an increased malnutrition risk with MUST, malnutrition with GLIM, and increased mortality. Additional studies are necessary to confirm these preliminary results.

Complex PTSD in asylum-seekers living in a humanitarian setting in Africa: A latent class analysis.

[Correction Notice: An Erratum for this article was reported online in Psychological Trauma: Theory, Research, Practice, and Policy on May 08 2023 (see record 2023-69929-001). In the original article, paragraphs 1 through 3 of the main text and the first paragraph under "PTSD and CPTSD Symptoms" in the Methods section were rewritten to avoid text similarity with that of a previously published article "Evidence of Distinct Profiles of ICD-11 Post-Traumatic Stress Disorder (PTSD) and Complex PTSD in a South African Sample," by James Rink and Gosia Lipinska (European Journal of Psychotraumatology, 2020, Vol. 11, No. 1, Article 1818965, https:// doi.org/10.1080/20008198.2020.1818965). All versions of this article have been corrected.] Objective: This study investigated ICD-11 posttraumatic stress disorder (PTSD) and complex PTSD (CPTSD) symptom profiles and their premigration, postmigration, and demographic predictors in a treatment-seeking sample of asylum-seekers in Agadez (Niger). METHOD: Participants were 126 asylum-seekers hosted in a large, isolated reception camp in the desert surroundings of Agadez (humanitarian site) or in a number of small urban hosting facilities (cases de passages) who completed measures of trauma exposure and PTSD/CPTSD symptoms. Latent class analysis (LCA) was used to identify symptom profiles, and predictors of class membership were identified via multinomial logistic regression. RESULTS: More asylum seekers met the criteria for CPTSD (74.6%) than PTSD (19.8%) and no gender differences were observed. LCA results identified two distinct groups: (a) a CPTSD class (69.0%); and (b) a PTSD class (31.0%). Membership in the CPTSD class was significantly predicted by the early age of the first traumatic event, levels of functional impairment and reception conditions. Specifically, those in the CPTSD class were more likely to live in the humanitarian site compared with those in the PTSD class. CONCLUSION: This study supported the validity of the ICD-11 construct of CPTSD in an asylum-seeker sample living in a low-income country. Moreover, the findings suggest that not only premigration factors (i.e., the early age of the first trauma) but also postmigration stressors (i.e., precarious reception conditions in large, isolated facilities) are important predictors of CPTSD symptoms with important implications regarding reception policies and the prevention of trauma-related mental disorders in asylum seekers and refugees.

Voice hearing in refugees survivors of traumatic events.

The term voice hearing (VH) refers to the experience of hearing voices in the absence of corresponding external stimuli and is considered a hallucinatory experience. According to the Diagnostic and Statistical Manual of Mental Disorders, fifth edition (DSM-5; American Psychiatric Association [APA], 2013), hallucinations are perception-like experiences that occur without an external stimulus. They are vivid and clear, with the full force and impact of normal perceptions, and not under voluntary control. Specifically, auditory hallucinations involve the perception of sound, most frequently of voices (i.e., auditory verbal hallucinations- AVHs) but sometimes of clicks or other noises, that are not restricted to the period of awakening or the onset of sleep. AVHs are usually experienced as voices, whether familiar or unfamiliar, that are perceived as distinct from the individual's own thoughts.

Evaluation of Vestibular Function in Patients Affected by Obstructive Sleep Apnea Performing Functional Head Impulse Test (fHIT).

Purpose: Obstructive sleep apnoea (OSA) is a common disease with significantly related complications. Since a connection between the vestibular nucleus and sleep regulator pathways has been demonstrated, vestibular evaluation in OSA patients was partially studied and none used functional head impulse test (fHIT) for this purpose. This paper aimed at evaluating the vestibular function in patients affected by OSA using fHIT, selecting patients who did not present any other related to cardiovascular, neurological, or metabolic diseases. Patients and Methods: Patients enrolled had a diagnosis of OSA by polysomnography type III and were cataloged according to American Association of Sleep Medicine criteria. Each patient underwent fHIT. Statistical significance was set at 0.05. Results: A total of 85 patients were enrolled in the study of which 50 had a diagnosis of OSA and were included in the case group, while 35 belonged to the control group. In 88.6% of subjects of the case group was evidenced a vestibular impairment with a substantial difference between the two study groups (p<0.05). Conclusion: The results show that the incidence of vestibular lesions in patients with obstructive sleep apnoea is underestimated and that fHIT can identify these lesions early.

Health Management in Italian Prisons during COVID-19 Outbreak: A Focus on the Second and Third Wave.

The SARS-CoV-2 spread is a threatening and challenging issue for correctional systems worldwide because of many factors, particularly overcrowding and of the intrinsic characteristics of the population. The prevention measures adopted by the Italian Government were aimed to protect and preserve both inmates' and prison workers' health. The present study aimed to evaluate the efficacy of the adopted strategies. METHODS: Data regarding Italian prisons' occupation and prisoners' population from January 2019 to June 2021, as well as the cumulative weekly increase of confirmed cases and the number of doses of vaccine administered among the population of inmates, the prison workers, and Italian population from November 2020 to the end of June 2021, were collected. RESULTS: Prisons' occupation dropped from 120% to 106% after the beginning of the pandemics. The confirmed cases between inmates were consistently lower than among the Italian population and prison workers. A time-series chart showed a time lag of one week between the peaks of the different population. CONCLUSIONS: The containing strategies adopted by the Italian correctional system have proved their effectiveness in terms of the prevention and protection of both inmate and staff health.

Symptoms related to gastrointestinal tract involvement and low muscularity in systemic sclerosis.

INTRODUCTION/OBJECTIVES: Gastrointestinal tract (GIT) involvement is frequently observed in systemic sclerosis (SSc) and may lead to nutritional impairment. The aim of the study was to assess the prevalence of symptoms related to GIT involvement and to analyze the possible association between gastrointestinal symptoms and low muscularity in SSc patients. METHODS: Sixty-nine consecutive patients (60 females, median age 53 (IQR 43-63), body mass index (BMI) 23.2 (IQR 20.9-24.6) kg/m2) with diagnosis of SSc admitted to our Scleroderma Unit were enrolled. Clinical status, anthropometric data, and bioelectrical impedance (Inbody 770, USA) analysis-assessed Fat-Free Mass Index (FFMI) were recorded upon enrollment. UCLA questionnaire was used to quantify GIT involvement with seven specific scales. RESULTS: Mean FFMI was 16.2 kg/m2 (IQR 15.2-17.6). The median UCLA total score was 0.53 (IQR 0.19-0.89). FFMI showed a significant negative correlation with UCLA total score (r = -0.29, p = 0.016) and UCLA distention/bloating (r = -0.35, p < 0.01). In 16 patients (23.1%), FFMI was reduced and UCLA distention/bloating was significantly higher (p = 0.039) in SSc patients with lower FFMI [1.75 (IQR 0.75-2.12) vs 0.75 (IQR 0.25-1.75)]. At multiple linear regression model, FFMI showed association with UCLA distention/bloating [beta coefficient - 0.315 (95% CI of beta coefficient: -0.591; -0.039), p = 0.026], BMI [beta coefficient 0.259 (95% CI of beta coefficient: 0.163; 0.355), p = 0.001], and disease duration [beta coefficient - 0.033 (95% CI of beta coefficient: -0.059; -0.007), p = 0.015]. CONCLUSIONS: In SSc, low FFMI is associated with symptoms related to GIT involvement, in particular with distension/bloating. Key Points • FFMI is associated with symptoms related to GIT involvement. • Low FFMI is associated with symptoms related to UCLA distention/bloating. • Malnutrition is not associated with symptoms related to GIT involvement.

Preoperative low-residue diet in gynecological surgery.

OBJECTIVE: To evaluate the impact of preoperative low-residue diet on intra- and postoperative outcomes among gynecological surgical patients. METHODS: This is a surgeon-blind, randomized controlled trial enrolling patients undergoing elective surgery for either benign disease or endometrial carcinoma. Patients were preoperatively randomized to receive either low-residue diet (arm A) or free diet (arm B) starting from three days before surgery. The primary outcome was the quality of the surgical field (scored using a 5-point scale, from poor to excellent). Secondary outcomes were postoperative pain (assessed through VAS scale), postoperative complications, operative time, time to first passage of flatus, length of hospital stay. Perioperative data were collected and compared between groups. RESULTS: A total of 96 patients were enrolled and randomized in arm A (n = 49; 51%) and arm B (n = 47; 49%). The mean age was 47.8 ± 15.6 years in arm A and 48.1 ± 11.3 years in arm B. Endometrial cancer patients were 16.3% in arm A and 10.6% in arm B, and patients with benign disease were 83.7% and 89.4%, respectively. The surgical evaluation of the small intestine was scored < 3 in 2.0% of arm A patients versus 31.9% in arm B (Odds Ratio (OR), 0.04 [95% CI, 0.01-0.35]; p < 0.001), and in 6.1% and 44.7% (OR, 0.08 [95% CI, 0.02-0.30]; p < 0.001), respectively, for large intestine. The mean operative time was 90.4 ± 33.4 min in arm A versus 111.6 ± 37.5 in arm B (Mean Difference (MD): -21.20 [95% CI, -35.43, -6.97]; p = 0.003). The number of patients who reported the time to first flatus within 24 h after surgery was significantly higher in arm A compared with arm B (77.6% vs 44.7%; OR, 4.28 [95% CI, 1.77-10.35]; p = 0.002). No significant differences in terms of postoperative complications, pain, and length of hospital stay were observed between the two groups. CONCLUSION: Introducing a preoperative low-residue diet could improve the quality of the surgical field and reduce both the operative duration and the time to first passage of flatus among patients undergoing gynecological surgery. Further large-scale studies are required to confirm these findings.

Use of Extracorporeal Membrane Oxygenation in Acutely Poisoned Pediatric Patients in United States: A Retrospective Analysis of the Extracorporeal Life Support Registry From 2003 to 2019.

OBJECTIVES: To describe the use of extracorporeal membrane oxygenation (ECMO) in the management of pediatric poisoning in the United States and to identify predictors of mortality. DESIGN: Retrospective cohort study. SETTING: Data reported to the Extracorporeal Life Support Organization by 76 U.S. ECMO centers from 2003 to 2019. PATIENTS: Pediatric patients (0-18 yr) receiving ECMO for poisoning. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: During our study period, 86 cases of acute poisoning were identified and included in the analysis. The median age was 12.0 year and 52.9% were female. The most commonly reported substance exposures were hydrocarbon (n = 17; 19.8%), followed by chemical asphyxiants (n = 14; 16.3%), neuroactive agents (n = 14; 16.3%), opioid/analgesics (n = 13; 15.1%), and cardiovascular agents (n = 12; 14.0%). Single substance exposures were reported in 83.7% of the cases. The intention of the exposure was unknown in 65.1%, self-harm in 20.9% and 10.5% was unintentional exposure. Fifty-six patients (65.1%) survived. Venoarterial ECMO was used more frequently than venovenous ECMO, and its use increased significantly during the study period (p < 0.01). A bimodal distribution of ECMO support was observed among two age groups: less than or equal to 3 years (n = 34) and 13-17 years (n = 41). Hemodynamic and metabolic parameters improved for all patients with ECMO. Persistent systolic hypotension, acidemia/metabolic acidosis, and elevated Pao2) after 24 hours of ECMO support were associated with mortality. Time from PICU admission to ECMO cannulation was not significantly different between survivors (24.0 hr; interquartile range [IQR], 11.0-58.0 hr) and nonsurvivors (30.5 hr; IQR, 10.0-60.2 hr; p = 0.58). ECMO duration and PICU length of stay were significantly longer in survivors than in nonsurvivors (139.5 vs 70.5 hr; p = 0.007 and 25.0 vs 4.0 d; p = 0.002, respectively). CONCLUSIONS: ECMO may improve the hemodynamic and metabolic status of poisoned pediatric patients. Persistent hypotension, acidemia/acidosis, and elevated Pao2 after 24 hours of ECMO were associated with mortality.
