ABSTRACT
INTRODUCTION: Osteoporosis poses a significant health concern, especially for individuals with chronic kidney disease (CKD). CKD disrupts mineral and bone metabolism, heightening the risk of fractures and complicating the management of osteoporosis. While anti-osteoporotic interventions aim to address bone health in CKD patients, ongoing research is essential to understand the comparative efficacy and safety of these medications, particularly in different CKD stages, notably in stages 4 and 5. METHODS: We searched PubMed/MEDLINE, EMBASE, and the Cochrane CENTRAL for randomized controlled trials assessing the efficacy and safety of osteoporosis interventions in CKD up to June 15, 2024. The analysis utilized the pooled odds ratio (OR) along with the corresponding 95% confidence interval (CI), employing Comprehensive Meta-Analysis software, version 3.0. To assess heterogeneity in the results of individual studies, we used Cochran's Q statistic and the I2 statistic. RESULTS: We analyzed 12 randomized controlled trials involving 31,027 participants, revealing a significantly lower risk of vertebral fractures with anti-osteoporotic agents (teriparatide, denosumab, romosozumab, raloxifene) compared to placebo (pooled OR, 0.28 [95% CI, 0.22-0.36]). Stratification by CKD stages showed a lower risk in Stages 1-3 but no significant reduction in stages 4 and 5. Teriparatide, denosumab, and romosozumab were effective in lowering fracture risk, whereas Raloxifene showed no significant effect. The lumbar spine, femoral neck, and total hip BMD showed no significant differences between anti-osteoporotic agents (denosumab, raloxifene, risedronate, alendronate, teriparatide) and placebo. However, romosozumab demonstrated a significantly greater BMD change in all kidney function categories. No reported side effects were observed in CKD stages 1-5 across the trials. CONCLUSIONS: Our meta-analysis highlights the effectiveness of anti-osteoporotic agents in lowering vertebral fracture risk in CKD patients, particularly in stages 1-3. However, this benefit is not apparent in stages 4 and 5, necessitating further research. Despite the absence of reported side effects in CKD patients, clinicians should carefully assess the suitability of these medications, considering individual risks and benefits.

BACKGROUND: Microcalcifications are acknowledged as a malignancy risk factor in multiple cancers. However, the prevalence and association of intrathoracic lymph node (ILN) calcifications with malignancy remain unexplored. METHODS: In this cross-sectional study, we enrolled patients with known/suspected malignancy and an indication for endosonography for diagnosis or ILN staging. We assessed the prevalence and pattern of calcified ILNs and the prevalence of malignancy in ILNs with and without calcifications. In addition, we evaluated the genomic profile and PD-L1 expression in lung cancer patients, stratifying them based on the presence or absence of ILN calcifications. RESULTS: A total of 571 ILNs were sampled in 352 patients. Calcifications were detected in 85 (24.1%) patients and in 94 (16.5%) ILNs, with microcalcifications (78/94, 83%) being the predominant type. Compared with ILNs without calcifications (214/477, 44.9%), the prevalence of malignancy was higher in ILNs with microcalcifications (73/78, 93.6%; P<0.0001) but not in those with macrocalcifications (7/16, 43.7%; P=0.93). In patients with lung cancer, the high prevalence of metastatic involvement in ILNs displaying microcalcifications was independent of lymph node size (< or >1 cm) and the clinical stage (advanced disease; cN2/N3 disease; cN0/N1 disease). The anaplastic lymphoma kinase (ALK) rearrangement was significantly more prevalent in patients with than in those without calcified ILNs (17.4% vs. 1.7%, P<0.001), and all of them exhibited microcalcifications. CONCLUSION: ILN microcalcifications are common in patients undergoing endosonography for suspected malignancy, and they are associated with a high prevalence of metastatic involvement and ALK rearrangement.

BACKGROUND: In children, asthma and sleep-disordered breathing (SDB) may affect quality of life (QoL), and SDB may complicate asthma management. OBJECTIVE: To evaluate the prevalence of SDB, its association with asthma control, and risk factors associated with SDB in a cohort of asthmatic children. The effects of asthma control and SDB on QoL were also investigated. METHODS: We consecutively recruited asthmatic children referred to our Pulmonology Service from December 1, 2022 to May 31, 2023. Data on anthropometrics, respiratory function, and allergies were collected. The prevalence of SDB was assessed by the Pediatric Sleep Questionnaire (PSQ). Asthma control status was assessed by the Childhood Asthma Control Test (C-ACT), while QoL was evaluated by the Pediatric Quality of Life Inventory (PedsQL) questionnaire. Factors associated with SDB were analyzed. RESULTS: A total of 78 asthmatic children aged 5-12 years were included. SDB was found in 37.2% of them, with a higher prevalence in children with uncontrolled versus well-controlled asthma (60.1% vs. 27.3%; p-value = 0.005). The C-ACT score was significantly lower in SDB-positive versus SDB-negative group, and uncontrolled asthma (C-ACT ≤19) was associated with a 4.15-fold increased risk of SDB. The PedsQL score was significantly lower in asthmatic children with than without SDB and was associated with lower SDB risk. SDB increased the risk of uncontrolled asthma in children, and asthmatic children with SDB had lower QoL. CONCLUSION: In asthmatic children, SDB affects both asthma control and QoL. Children with uncontrolled asthma should be referred for polysomnography to identify a possible underlying SDB.

Background: Autism spectrum disorder (ASD) is a persistent neurodevelopmental disorder frequently co-occurring with attention-deficit/hyperactivity disorder (ADHD) and behavior-related disorders. While behavioral therapy is the first-line option to manage the core symptoms of ASD, pharmacological therapy is sometimes needed to treat acute problems, such as agitation and aggressive behaviors. Recent guidelines recommend the use of neuroleptics to reduce psychomotor agitation in patients with ASD. However, as children with ASD are often drug-resistant, alternative treatments are often justified. Reports from the literature have indicated that intravenous valproate (IV-VPA) can be effective in reducing agitation in psychiatric patients, with a lower frequency of adverse events compared to conventional treatments. However, as the related findings are occasionally inconsistent, IV-VPA is not yet an approved option in the context of clinical psychiatry. We aim to improve knowledge of the IV-VPA treatment option for emergency psychiatric treatment in pediatric patients. Methods: We report the case of an 11-year-old boy suffering from a complex neurodevelopmental condition who experienced a psychotic episode with severe aggressive and disruptive behaviors and was successfully treated with IV-VPA. Furthermore, we provide an updated literature review on this topic. Conclusion: In our case, first-line therapies proved to be ineffective. To the contrary, IV-VPA led to safe and prompt clinical success, which is in line with other reports. Based on our literature review, IV-VPA can be highly effective and reduces the risk of adverse events that frequently occur with the use of high-dose standard medications in emergency psychiatry.
ABSTRACT
BACKGROUND: Epigenetic biomarkers in cancer have emerged as promising tools for early detection, prognosis, and treatment response prediction. In cervical cells, hypermethylation of the host and viral HPV-genome increases with the severity of lesions, providing a useful biomarker in the triage of hr-HPV-positive women and during treatment. The present study focuses on evaluating the clinical performance of the FAM19A4/miR124-2 methylation test in a population-based cervical screening program. METHODS: Previously collected cervical samples, after bisulfite-converted DNA, were analyzed by PreCursor-M+ kit (distributed by Fujirebio Europe), for DNA methylation. The sensitivity, specificity, and negative/positive predictive values of DNA methylation were compared to histology, colposcopy, the HPV-DNA test, and cytology results. RESULTS: Among the 61-sample set, the specificity of methylation vs. positive histology (≥CIN2) and colposcopy (≥G2) were 87% and 90%, whereas the sensitivity was 50% and 33.3%, respectively. The combination of methylation analysis with standard methods increases diagnostic accuracy. CONCLUSIONS: Overall, we found a good specificity of DNA methylation in comparison to currently used techniques. Further larger studies could support the use of FAM19A4/miR124-2 as reliable biomarkers in the prevention of cervical cancer as triage in the screening protocol.
ABSTRACT
INTRODUCTION: Patients with central neoplasms and haemoptysis show low survival rates. Symptom control without recurrence 48 h after bronchoscopic interventions may improve the prognosis of these patients. Bronchoscopic argon plasma coagulation (APC) is a useful technique for endobronchial management of haemoptysis in patients with central malignancies. Nevertheless, limited data are available in the literature on its efficacy and safety and the main predictors of success are still unclear. METHODS: An observational, prospective, single-centre cohort study was carried out to assess the efficacy (i.e., immediate bleeding cessation without recurrence during the following 48 h) of bronchoscopic APC in the treatment of patients with haemoptysis caused by endobronchial malignancies and the main predictors of success. RESULTS: A total of 76 patients with median age 75 years (interquartile range: 65-79) were enrolled. 67 (88.2%) patients had bleeding cessation without recurrence 48 h after bronchoscopic APC. A low rate of non-serious adverse events (5.3%) was recorded and a low (7.6%) recurrence rate of haemoptysis at 3.5 months after the procedure was also shown. No clinical, demographic and endoscopic variables related to a successful procedure at 48 h were found. CONCLUSION: This study demonstrates that bronchoscopic APC is an effective procedure in the treatment of patients with haemoptysis caused by endobronchial malignancies, regardless of the clinical characteristics of the patients, the endoscopic and histological features of the neoplasm and the severity of the symptom. Furthermore, it shows a low rate of complications and long-term efficacy in bleeding control.
ABSTRACT
BACKGROUND: High blood eosinophils seem to predict exacerbations and response to inhaled corticosteroids (ICS) treatment in patients with chronic obstructive pulmonary disease (COPD). The aim of our study was to prospectively evaluate for 2 years, blood and sputum eosinophils in COPD patients treated with bronchodilators only at recruitment. METHODS: COPD patients in stable condition treated with bronchodilators only underwent monitoring of lung function, blood and sputum eosinophils, exacerbations and comorbidities every 6 months for 2 years. ICS was added during follow-up when symptoms worsened. RESULTS: 63 COPD patients were enrolled: 53 were followed for 1 year, 41 for 2 years, 10 dropped-out. After 2 years, ICS was added in 12/41 patients (29%) without any statistically significant difference at time points considered. Blood and sputum eosinophils did not change during follow-up. Only FEV1/FVC at T0 was predictive of ICS addition during the 2 year-follow-up (OR:0.91; 95% CI: 0.83-0.99, p = 0.03). ICS addition did not impact on delta (T24-T0) FEV1, blood and sputum eosinophils and exacerbations. After 2 years, patients who received ICS had higher blood eosinophils than those in bronchodilator therapy (p = 0.042). Patients with history of ischemic heart disease increased blood eosinophils after 2 years [p = 0.03 for both percentage and counts]. CONCLUSIONS: Blood and sputum eosinophils remained stable during the 2 year follow-up and were not associated with worsened symptoms or exacerbations. Almost 30% of mild/moderate COPD patients in bronchodilator therapy at enrollment, received ICS for worsened symptoms in a 2 year-follow-up and only FEV1/FVC at T0 seems to predict this addition. History of ischemic heart disease seems to be associated with a progressive increase of blood eosinophils.

This study investigates the effect of surface modifications of the titanium substrate on the growth of electrochemically deposited copper. These materials are intended to serve as cathodes in the electroreduction of nitrates in aqueous solutions. Surface modifications included the use of hydrogen fluoride for titanium etching and anodization to promote the growth of a structured titania nanotube array. The effect of an intermediate calcination step for the nanotubes before deposition was assessed along with a comparison to an untreated substrate electrode. The materials were comprehensively characterized by SEM, XRD, contact angle, potentiodynamic tests, EIS, and cyclic voltammetry. Their electrocatalytic ability was tested in the reduction of aqueous solutions containing nitrates. The results reveal that surface finishing impacted the shape and size of the Cu microparticles, as well as the nucleation mechanism enabling a crystal-facet-controllable synthesis. All the materials exhibited microsized copper particles with a spherical shape with some clusters. On the etched titanium surface, a high number of heterogeneous submicroscopic particles were also present. The thermally treated anodized substrate promoted the development of a combination of sparse microparticles corresponding to defect sites in amorphous titanium and the presence of a diffuse coating of octahedral nanosized particles whose growth was promoted by the tetragonal structure of anatase crystals. Electrochemical tests display reduced charge transfer resistance upon copper deposition on the modified substrates, which is indicative of the enhanced conductivity of the coated materials. Additionally, cyclic voltammetry and electrolysis experiments reveal the electrodes' potential for nitrate reduction, showing a better response for the etched titanium substrate (30% nitrate removal, after 2 h at 25 mA cm-2).
ABSTRACT
BACKGROUND: Hemoptysis is a challenging and potentially life-threatening medical condition. The most appropriate diagnostic work-up is debated and several diagnostic approaches are implemented worldwide. METHODS: An international, online survey was carried out to investigate the current practice of the diagnostic work-up of patients with hemoptysis of unknown etiology. RESULTS: Overall, 604 physicians responded to the survey. At baseline, chest X-ray was suggested as the first diagnostic investigation by 342 (56.6%) participants. Computed tomography (CT) was suggested in each patient with non- and life-threatening hemoptysis by 310 (51.3%) and 526 (87.1%) respondents, respectively. Contrast-enhanced CT is the currently preferred technique (333, 55.1%). In case of patchy ground glass opacities and negative CT, 287 (47.5%) and 222 (36.8%) participants, respectively, would always offer bronchoscopy. Otorhinolaryngological evaluation was mostly suggested in case of suspected upper airways bleeding before other investigations (212, 35.1%). A follow-up was recommended for idiopathic hemoptysis by the majority of the participants (316, 52.3%). A multidisciplinary assessment is deemed crucial for each patient with life-threatening hemoptysis (437, 72.4%). CONCLUSIONS: Chest X-ray and contrast-enhanced CT are currently preferred as the first diagnostic investigations, regardless of hemoptysis severity. Bronchoscopy is suggested in case of negative radiological examination and when CT shows only ground glass opacities. Otorhinolaryngological evaluation is advised before any other investigations when upper airways bleeding is suspected. Patients with idiopathic hemoptysis are suggested to undergo a clinical follow-up and in case of life-threatening bleeding a multidisciplinary assessment is deemed crucial. Due to the heterogeneous approaches a consensus statement would be needed.

BACKGROUND: Preliminary studies suggest that moderate ARDS and acute renal failure might benefit from extracorporeal CO2 removal (ECCO2R) coupled with CRRT. However, evidence is limited and potential for this coupled treatment may need to be explored. The aim of the present study was to evaluate whether a protective driving pressure was obtained applying low-flow ECCO2-R plus CRRT in patients affected by moderate ARDS with COVID-19 compared to an historical group without COVID-19. METHODS: A case-control study has been conducted comparing a group of consecutive moderate ARDS patients presenting AKI and affected by COVID-19, who needed low-flow ECCO2-R plus CRRT to achieve an ultra-protective ventilatory strategy, with historical group without COVID-19 that matched for clinical presentation and underwent the same ultra-protective treatment. VT was set at 6 mL/kg predicted body weight then ECCO2R was assessed to facilitate ultra-protective low VT ventilation to preserve safe Pplat and low driving pressure. RESULTS: ECCO2R+CRRT reduced the driving pressure from 17 (14-18) to 11.5 (10-15) cmH2O (p<0.0004) in the fourteen ARDS patients by decreasing VT from 6.7 ml/kg PBW (6.1-6.9) to 5.1 (4.2-5.6) after 1 hour (p <0.0001). In the ARDS patients with COVID-19, the driving pressure reduction was more effective from baseline 18 (14-24) cmH2O to 11 (10-15) cmH2O (p<0.004), compared to the control group from 15 (13-17) to 12(10-16) cmH2O (p< 0.03), after one hour. ECCO2R+CRRT did not affected 28 days mortality in the two groups, while we observed a shorter duration of mechanical ventilation (19 {7-29} vs 24 {22-38} days; p=0.24) and ICU length of stay (19 {7-29} vs 24 {22-78} days; p=0.25) in moderate ARDS patients with COVID-19 compared to control group. CONCLUSIONS: In moderate ARDS patients with or without COVID-19 disease, ECCO2R+CRRT may be and effective supportive treatment to reach protective values of driving pressure unless severe oxygenation defects arise requiring ECMO therapy initiation.
ABSTRACT
BACKGROUND: Improving patient activation may be an effective way to reduce healthcare costs and improve patient outcomes after surgery. OBJECTIVE: To determine whether preoperative patient activation is associated with delayed discharge (i.e., length of stay >24â¯h) after elective laparoscopic cholecystectomy. Postoperative symptoms, unscheduled access to healthcare facilities within seven days of surgery, unplanned hospital readmissions, and postoperative complications were analyzed as secondary outcomes. DESIGN: This cohort study was a secondary analysis of the DeDiLaCo study (Delayed Discharge after day-surgery Laparoscopic Cholecystectomy) collecting data of patients undergoing elective laparoscopic cholecystectomy during 2021 in Italy. Data was analyzed from June 2022 to April 2023. SETTING: 90 Italian surgical centers participating in the study. PARTICIPANTS: 4708 adult patients with an instrumental diagnosis of gallbladder disease and undergoing laparoscopic cholecystectomy. Patient activation was assessed using the Italian translation of Patient Activation Measure in the preoperative setting. RESULTS: Of 4532 cases analyzed the median (IQR) Patient Activation Measure score was 80.3 (71.2-92.3). Participants were on average 55.5â¯years of age and 58.1â¯% were female. Two groups based on the activation level were created: 270 (6â¯%) had low activation, and 4262 had high activation. The low activation level was associated with the likelihood of delayed discharge (odds ratio [OR] 1.47, 95â¯% CI, 1.11-1.95; Pâ¯=â¯.008), higher symptom burden (OR 1.99, 95â¯% CI 1.49-2.66, Pâ¯<â¯.0001), and unplanned healthcare utilization within seven days after hospital discharge (OR 1.85, 95â¯% CI, 1.29-2.63; Pâ¯=â¯.001). There was no difference between the high and low activation groups in the incidence of postoperative complications (OR 1.28, 95â¯% CI, 0.95-1.73; Pâ¯=â¯.10) and hospital readmission after discharge (OR 0.95, 95â¯% CI, 0.30-3.05; Pâ¯=â¯.93). CONCLUSIONS: Our results suggest that patients with low activation have 1.47 times the risk of delayed discharge compared with patients with higher activation, almost twice the risk of the onset of postoperative symptoms, and 1.85 times the risk of unscheduled use of hospital services. Screening for patient activation in the preoperative setting could not only identify patients not suitable for early discharge, but more importantly, help physicians and nurses develop tailored interventions.

Objective: To describe the burden of moderate to severe exacerbations and all-cause mortality; the secondary objectives were to analyze treatment patterns and changes over follow-up. Design: Observational, multicenter, retrospective, cohort study with a three year follow-up period. Setting: Ten Italian academic secondary- and tertiary-care centers. Participants: Patients with a confirmed diagnosis of COPD referring to the outpatient clinics of the participating centers were retrospectively recruited. Primary and Secondary Outcome Measures: Annualized frequency of moderate and severe exacerbations stratified by exacerbation history prior to study enrollment. Patients were classified according to airflow obstruction, GOLD risk categories, and divided in 4 groups: A = no exacerbations; B = 1 moderate exacerbation; C = 1 severe exacerbation; D = ≥2 moderate and/or severe exacerbations. Overall all-cause mortality stratified by age, COPD category, and COPD therapy. A logistic regression model assessed the association of clinical characteristics with mortality. Results: 1111 patients were included (73% males), of which 41.5% had a history of exacerbations. As expected, the proportion of patients experiencing ≥1 exacerbation during follow-up increased according to pre-defined study risk categories (B: 79%, C: 84%, D: 97.4%). Overall, by the end of follow-up, 45.5% of patients without a history of exacerbation experienced an exacerbation (31% of which severe), and 13% died. Deceased patients were significantly older, more obstructed and hyperinflated, and more frequently active smokers compared with survivors. Severe exacerbations were more frequent in patients that died (23.5%, vs 10.2%; p-value: 0.002). Chronic heart failure and ischemic heart disease were the only comorbidities associated with a higher odds ratio (OR) for death (OR: 2.2, p-value: 0.001; and OR: 1.9, p-value: 0.007). Treatment patterns were similar in patients that died and survivors. Conclusion: Patients with a low exacerbation risk are exposed to a significant future risk of moderate/severe exacerbations. Real life data confirm the strong association between mortality and cardiovascular comorbidities in COPD.

The risk of cardiac involvement with electrophysiological abnormalities during COVID-19 infection has been reported in adults but remains poorly studied in children. Our aim was to determine the frequency of cardiac involvement and the necessity of routine cardiac evaluation in children hospitalized for COVID-19. This observational study included 127 children, with a median (IQR) age of 2 (0.83-6.0) years, who were hospitalized for COVID-19 between 1 January 2021 and 31 August 2022, 62 (48.8%) of whom were males. Each patient underwent an ECG on admission and discharge as well as a laboratory assessment. A comparison between patients with COVID-19 and healthy controls showed significantly higher HR (p < 0.0001) and lower PR values (p = 0.02) in the first group. No arrhythmias or other electrocardiographic abnormalities were detected during hospitalization. The median levels of troponin, NT-proBNP, ferritin, and D-dimer were significantly higher in children aged <2 years, but they fell within the normal range for their age. Our results indicate that a detectable cardiac involvement is very rare in children hospitalized for COVID-19 and not suffering from Multisystem Inflammatory Syndrome in Children (MIS-C) and suggest that routine electrocardiographic assessment is not mandatory in these patients in the absence of cardiac symptoms/signs.
ABSTRACT
Recurrent respiratory papillomatosis (RRP) is a non-malignant disease, characterized by the production of wart-like growths in the respiratory tract, affecting both young people and adults (juvenile-onset recurrent respiratory papillomatosis, JORRP, and adult-onset recurrent respiratory papillomatosis, AORRP, respectively). Infection caused by human papillomavirus (HPV) is known as the main factor involved in RRP development. Complications of RRP may rarely occur, including lung involvement and malignant transformation. The present systematic review aimed to evaluate the prevalence of severe complications, such as lung involvement and lung tumor in JORRP and AORRP patients, and assess the role of HPV genotypes in the progression of disease severity following the guideline for reporting systematic reviews and meta-analysis (PRISMA Statement). A total of 378 studies were found on PubMed and Scopus using the following MESH terms: "recurrent respiratory papillomatosis and lung tumor" and "pulmonary tumor and recurrent respiratory papillomatosis". Basing on inclusion and exclusion criteria, a total of 11 studies were included in the systematic review. We found a pooled prevalence of 8% (95% CI: 4-14%; I2: 87.5%) for lung involvement in RRP patients. In addition, we found a pooled risk difference of 5% in lung involvement between JORRP and AORRP (95% CI: -7-18%; I2: 85.6%, p-value: 0.41). Among patients with lung involvement, we observed a pooled prevalence of lung tumor of 4% (95% CI:1-7%; I2: 67.1%) and a pooled prevalence mortality for this group of 4% (95% CI:2-6%; I2: 0%). Overall, the positivity rate for HPV-6 and -11 in patients with RRP was 91%. Considering only cases with pulmonary involvement, the pooled prevalence for HPV-11 was 21% (95% CI: 5-45%; I2: 77.2%). Our results evidenced a low/middle risk of pulmonary involvement and lung tumor in JORRP and AORRP patients, with an increased risk for HPV-11-positive patients. Further studies should be performed to improve knowledge and adopt preventive measures to contrast the progression to severe diseases in RRP patients.
ABSTRACT
Introduction: Vitamin D deficiency is a common public health issue worldwide. The purpose of this study was to investigate the vitamin D status and its potential determinants in children residing in Sardinia (40°N), Italy. Methods: A total of 182 children (males: 51.7%; median age: 9 years) were enrolled over a 12-month period. Serum 25(OH)D was measured by an immune-chemiluminescence assay. A questionnaire was used to gather information on other variables, including passive smoke exposure. Results: Mean (SD) serum 25(OH)D was 25.2 (8.3) ng/mL for the whole group. The majority (n=123, 67.6%) of children had vitamin D sufficient values >20 ng/mL, while about 1/3 had vitamin D insufficient/deficient values (≤20 ng/mL (n=59, 32.4%). Among the variables investigated, passive smoke exposure was significantly associated with insufficient 25(OH)D levels (p<0.0001). Conclusion: Our results further prove that hypovitaminosis D is common in the Italian children and documented that passive smoke exposure is a significant risk factor for hypovitaminosis D.
ABSTRACT
INTRODUCTION/AIMS: The global incidence and prevalence of myasthenia gravis (MG) range between 6-31/million and 10-37/100,000, respectively. Sardinia is a high-risk region for different immune-mediated disorders, but the epidemiology of MG remains unclear. We determined the epidemiology of MG with acetylcholine receptor (AChR)-immunoglobulin G (IgG) and muscle-specific tyrosine kinase (MuSK)-IgG in the district of Sassari (North-Western Sardinia; population, 325,288). METHODS: From the laboratory of the University Hospital of Sassari (reference for AChR/MuSK-IgG testing in Sardinia since 1998) and the main neurology units in Sardinia, we retrospectively identified MG patients with (1) AChR-IgG and/or MuSK-IgG positivity by radioimmunoprecipitation assay; and (2) residency in the district of Sassari. Incidence (January 2010-December 2019) and prevalence (December 31, 2019) were calculated. RESULTS: A total of 202 patients were included (incident, 107; prevalent, 180). Antibody specificities were AChR (n = 187 [93%]) and MuSK (n = 15 [7%]). The crude MG incidence (95% confidence interval) was 32.6 (26.8-39.2)/million, while prevalence was 55.3 (47.7-63.9)/100,000. After age-standardization to the world population, incidence decreased to 18.4 (14.3-22.5)/million, while prevalence decreased to 31.6 (26.1-37.0)/100,000. Among incident cases, age strata (years) at MG onset were: <18 (2%), 18-49 (14%), 50-64 (21%), and ≥65 (63%). DISCUSSION: Sardinia is a high-risk region for MG, with a prevalence that exceeds the European threshold for rare disease. Identification of the environmental and genetic determinants of this risk may improve our understanding of disease pathophysiology.

PURPOSE: The Italian Island of Sardinia (population, 1,578,146) is recognized for the high risk of multiple sclerosis (MS) but the epidemiological burden of other less common demyelinating diseases of the central nervous system (CNS), such as aquaporin-4-IgG-positive neuromyelitis optica spectrum disorder (AQP4-IgG+NMOSD), is unknown. In this study, we determined the incidence and prevalence of AQP4-IgG+NMOSD in Sardinia over a ten-year study period (2013-2022). METHODS: Patients with a diagnosis of AQP4-IgG+NMOSD (per 2015 IPND diagnostic criteria) were retrospectively identified using two sources: (1) Archives of the reference and only laboratory for AQP4-IgG testing in Sardinia; and (2) medical records of the four MS units in the island. Incidence (January 2013-December 2022) and prevalence (December 31, 2022) were calculated. RESULTS: A total of 45 cases were included: incident, 31; prevalent, 41. The median age (range) at disease presentation was 51 (6-78) years; female/male ratio was 9:1. The crude (95 % CI) incidence and prevalence were 1.9 (1.3-2.7) per million and 2.6 (1.9-3.5) per 100,000, respectively. Prevalence increased from 2013 (1.1 per 100,000) to 2022 (2.6 per 100,000); p = 0.002. After age-standardization to the world, incidence and prevalence (95 % CI) decreased to 1.3 (0.7-2) per million and 1.8 (1.3-2.3) per 100,000, respectively. Coexisting immune-mediated disorders, mostly autoimmune thyroiditis, were reported in 50 % of patients. CONCLUSIONS: The epidemiology of AQP4-IgG+NMOSD in Sardinia is overall in line with other Caucasian populations. The high MS risk in the island seems disease-specific and not associated with an increased risk of other CNS demyelinating disorders, confirming different pathophysiology.

ABSTRACT
BACKGROUND: Several scores aimed at predicting COVID-19 progression have been proposed. As the variables vaccination and early SARS-CoV-2 treatment were systematically excluded from the prognostic scores, the present study's objective was to develop a new model adapted to the current epidemiological scenario. METHODS: We included all patients evaluated by the Infectious Disease Unit in Sassari, with SARS-CoV-2 infection and without signs of respiratory failure at the first evaluation (P/F > 300). Disease progression was defined by the prescription of supplemental oxygen. In addition, variables related to demographics, vaccines, comorbidities, symptoms, CT scans, blood tests, and therapies were collected. Multivariate logistic regression modelling was performed to determine factors associated with progression; any variable with significant univariate test or clinical relevance was selected as a candidate for multivariate analysis. Hosmer-Lemeshow (HL) goodness of fit statistic was calculated. Odds ratio values were used to derive an integer score for developing an easy-to-use progression risk score. The discrimination performance of the risk index was determined using the AUC, and the best cut-off point, according to the Youden index, sensitivity, specificity, predictive value, and likelihood ratio, was chosen. RESULTS: 1145 patients [median (IQR) age 74 (62-83) years; 53.5% males] were enrolled; 336 (29.3%) had disease progression. Patients with a clinical progression were older and showed more comorbidities; furthermore, they were less vaccinated and exposed to preventive therapy. In the multivariate logistic regression analysis, age ≥ 60 years, COPD, dementia, haematological tumours, heart failure, exposure to no or one vaccine dose, fever, dyspnoea, GGO, consolidation, ferritin, De Ritis ≥ 1.2, LDH, and no exposure to early anti-SARS-CoV-2 treatment were associated with disease progression. The final risk score ranged from 0 to 45. The ROC curve analysis showed an AUC of 0.92 (95% CI 0.90-0.93) with a 93.7% specificity and 72.9% sensitivity. Low risk was defined when the cut-off value was less than 23. Three risk levels were identified: low (0-23 points), medium (24-35), and high (≥ 36). CONCLUSIONS: The proportion of patients with progression increases with high scores: the assessment of the risk could be helpful for clinicians to plan appropriate therapeutic strategies.
