Non-alcoholic fatty liver disease and the risk of fibrosis in Italian primary care services: GPS-NAFLD Study: GPS-NAFLD Study.

BACKGROUND AND AIMS: The prevalence of non-alcoholic fatty liver disease (NAFLD) is increasing globally. This study aimed to determine the prevalence of NAFLD and the probability of liver fibrosis in Italian primary care services. METHODS: We carried out a population-based and nested case-control study including all individuals aged 18 years and above registered at Italian primary care services. Data were collected from the general practitioners' network from 2010 to 2017. NAFLD cases were identified via the ICD-9-CM and Hepatic Steatosis Index score > 36 and were matched each up to 10 controls. Other causes of liver diseases were excluded. The risk of fibrosis was assessed using the FIB-4 and NAFLD fibrosis scores (NFS). RESULTS: NAFLD was present in 9% of the primary care population with high regional variability. Among NAFLD subjects: 25% had diabetes, 10% had chronic kidney disease, 11% had cardiovascular disease and 28% were obese. Furthermore, 30% had at least two comorbidities and 13% had cirrhosis. Once cirrhosis was excluded, the risk of any degree of fibrosis was 13.8% with NFS and 20.5% with FIB-4 in subjects <65 years. CONCLUSIONS: Even if there is an identification gap in primary care, recorded cases with NAFLD have a high frequency of associated comorbidities. Despite regional variability, a close relation between cirrhosis and NAFLD exists (OR: 3.48, 95% CI: 3.23-3.76). Therefore, the use of non-invasive tests should be promoted in primary care as a useful tool for the early identification of fibrosis risk, independently of evidence of steatosis.

Fib-4 score is able to predict intra-hospital mortality in 4 different SARS-COV2 waves.

Increased values of the FIB-4 index appear to be associated with poor clinical outcomes in COVID-19 patients. This study aimed to develop and validate predictive mortality models, using data upon admission of hospitalized patients in four COVID-19 waves between March 2020 and January 2022. A single-center cohort study was performed on consecutive adult patients with Covid-19 admitted at the Fondazione Policlinico Gemelli IRCCS (Rome, Italy). Artificial intelligence and big data processing were used to retrieve data. Patients and clinical characteristics of patients with available FIB-4 data derived from the Gemelli Generator Real World Data (G2 RWD) were used to develop predictive mortality models during the four waves of the COVID-19 pandemic. A logistic regression model was applied to the training and test set (75%:25%). The model's performance was assessed by receiver operating characteristic (ROC) curves. A total of 4936 patients were included. Hypertension (38.4%), cancer (12.15%) and diabetes (16.3%) were the most common comorbidities. 23.9% of patients were admitted to ICU, and 12.6% had mechanical ventilation. During the study period, 762 patients (15.4%) died. We developed a multivariable logistic regression model on patient data from all waves, which showed that the FIB-4 score > 2.53 was associated with increased mortality risk (OR = 4.53, 95% CI 2.83-7.25; p ≤ 0.001). These data may be useful in the risk stratification at the admission of hospitalized patients with COVID-19.

Clinical characteristics of metabolic associated fatty liver disease (MAFLD) in subjects with myotonic dystrophy type 1 (DM1).

BACKGROUND: Myotonic dystrophy type 1 (DM1) is a rare inherited neuromuscular disease associated with insulin resistance, and its association with metabolically associated fatty liver disease (MAFLD) has never been explored in prospective studies. The aim of this study was to assess the clinical features of MAFLD in DM1 patients. METHODS: We investigated the prevalence and the diagnostic features of MAFLD in a cohort of 29 outpatient fully characterized DM1 patients; afterward, we compared the selected cohort of DM1-MAFLD individuals with a propensity-matched cohort of non-DM1-MAFLD RESULTS: 13/29 (44.83%) DM1 patients received a clinical diagnosis of MAFLD. Compared to DM1 patients with normal liver, DM1-MAFLD individuals showed a higher male prevalence (p = 0.008), BMI (p = 0.014), HOMA score (p = 0.012), and GGT levels (p = 0.050). The statistical comparison showed that the DM1-MAFLD group had a more severe MAFLD according to the FIB4 score than non-DM1-MAFLD patients. This association of a more severe form of liver disease with DM1 remained significant after logistic regression analysis (OR: 6.12, 95% CI 1.44- 26.55).

Microbiological ascertainment in patients with pneumonia: the experience of a teaching hospital in Rome.

OBJECTIVES: Pneumonia still remains a problem from the clinical and public health viewpoint because of the relevant epidemiological burden. The etiological diagnosis is important in the light of avoiding unnecessary antibiotic treatment and choosing the most appropriate therapeutical approach. This study is aimed at providing evidence on the proportion of microbiological ascertainment in pneumonia-related hospitalizations in one of the most important teaching hospitals in Rome. METHODS: The study relied on the record linkage of two administrative databases of the same hospital: the electronic hospital discharge register and the microbiology laboratory surveillance database. RESULTS: 2819 records were identified, where 46% had a microbiological ascertainment, significantly higher in males than in females (51% vs 40%) and in cases of pneumonia reported in secondary diagnosis instead of primary diagnosis (52% vs 42%). Medical patients had significantly lower proportion of ascertainment compared to surgical patients (43% vs 67%) whereas there were not differences between patients with emergency and elective admission. The overall mortality was 17%. Mortality was significantly higher: in surgical compared to medical patients (27% vs 15%), in ventilated compared to not ventilated patients (41% vs 11%), in cases with secondary diagnosis of pneumonia compared to a primary diagnosis (23% vs 11% ) and in hospitalized in intensive care unit-ICU- rather than in non-ICU (71% vs 12%). CONCLUSION: The proportion of microbiological ascertaiment in pneumonia remains less than 50%. Albeit in line with other evidence, this result should call the attention on the impact of unknown etiological diagnosis on antibiotic treatment and resistance.

The prognostic value of anterior commissure involvement in T1 glottic cancer: A systematic review and meta-analysis.

OBJECTIVE: The anterior commissure is considered a laryngeal subsite, but it is not taken into account in the current T-staging system. The impact of anterior commissure involvement (ACI) on the oncologic outcomes of T1 glottic tumors has not been well defined and remains controversial. The aim of this study was to assess the influence of ACI in the prognosis of T1 glottic tumors. METHODS: A systematic review and meta-analysis of observational studies was performed by including studies published up to July 2019. Studies were selected if they had investigated the local control rate (LCR) at 5 years of clinical stage I (T1 and N0) glottic squamous cell carcinoma with and without ACI. The difference in LCR at 5 years between T1 glottic tumors without and with ACI was evaluated. RESULTS: The meta-analysis showed that the difference in LCR at 5 years between T1 glottic tumors without and with ACI is 12% (95% confidence interval: 8%-16%, p < 0,0001, I2 = 34.81%). CONCLUSIONS: Our study pointed out that the anterior commissure involvement is a negative prognostic factor in LCR at 5 years for T1 glottic tumors. Our results suggest the need to consider ACI in the T staging of glottic tumors. Laryngoscope, 130:1932-1940, 2020.
