The role of the circadian timing system in sarcopenia in old age: a scoping review.

Purpose: Sarcopenia is a progressive and generalized skeletal muscle disorder, involving the accelerated loss of skeletal muscle mass and function, associated with an increased probability of adverse outcomes including falls. The circadian timing system may be involved in molecular pathways leading to sarcopenia in older adults. We aimed to provide an updated and systematic map of the available evidence on the role of the circadian timing system in sarcopenia, specifically related to the aging process.

Wearable sensors for monitoring caregivers of people with dementia: a scoping review.

Purpose: Caregivers of people with dementia often face a demanding care burden that may lead to adverse physical and psychological outcomes. Wearable sensors are becoming a valuable tool for preventive care. We aimed to provide the first systematic map of the published evidence on the use of wearable sensors to monitor caregivers of people with dementia.

Predictors of clinical trajectories of patients with acutely decompensated cirrhosis. An external validation of the PREDICT study.

Background And Aims: The PREDICT study recently showed that acutely decompensated (AD) patients with cirrhosis can present three different clinical phenotypes in the 90 days after admission: (1) pre-ACLF, developing acute-on-chronic liver failure (ACLF); (2) unstable decompensated cirrhosis (UDC), being re-admitted for AD without ACLF and (3) stable decompensated cirrhosis (SDC), not presenting readmission or ACLF. This study aimed to externally validate the existence of these three distinct trajectories and to identify predictors for the occurrence of each trajectory.

Methods: Baseline data, 3-month ACLF and readmission incidence and 1-year survival were analysed in a prospective cohort of patients admitted for AD.

Nonalcoholic fatty liver disease: an update.

Purpose Of Review: We discuss two recent controversial issues in the research field of fatty liver: the proposal to replace nonalcoholic fatty liver disease (NAFLD) with metabolically associated fatty liver disease (MAFLD) and the suggestion to extend to primary care the noninvasive testing for liver fibrosis that was developed for secondary care.

Recent Findings: There is preliminary evidence that MAFLD-only patients are at greater risk of fibrosis than NAFLD-only patients. There are a large number of false positives associated with the downshift of noninvasive testing for liver fibrosis from secondary to primary care.

COVID-19-Related Death in Patients with Alcohol or Substance Use Disorders.

Background: People with substance or alcohol use disorders (SUDs/AUDs) are likely to be more vulnerable to COVID-19 infection than the general population, but the evidence of COVID-19-related mortality in these patients is unclear.

Objectives: The aim of the study was to verify whether patients with AUD and SUD have a higher mortality rate for COVID-19-related mortality compared to the general population.

Method: We performed a follow-up study to assess mortality in 2020 in a cohort of patients diagnosed for the first time with AUDs or SUDs at the Public Health Services in the metropolitan area of Bologna (Northern Italy) from 2009 to 2019.

Adaptive Quality of Service Control for MQTT-SN.

Internet of Things and wireless sensor network applications are becoming more and more popular these days, supported by new communication technologies and protocols tailored to their specific requirements. This paper focuses on improving the performance of a Wireless Sensor Network operated by the MQTT-SN protocol, one of the most popular publish/subscribe protocols for IoT applications. In particular, we propose a dynamic Quality of Service (QoS) controller for the MQTT-SN protocol, capable of evaluating the status of the underlying network in terms of end-to-end delay and packet error rate, reacting consequently by assigning the best QoS value to a node.

Mortality and its association with chronic alcohol-related diseases in patients admitted to the emergency department for acute alcoholic intoxication: retrospective cohort study.

We assessed long-term mortality and its association with chronic alcohol-related diseases in patients admitted to the emergency department (ED) because of acute alcoholic intoxication (AAI). A retrospective cohort study was performed at the ED of Sant'Orsola-Malpighi Hospital, Bologna, Italy. 3304 patients, corresponding to 6415 admissions for AAI, who accessed the ED from January 1, 2005, to December 31, 2017, were studied.

Sarcopenia and Vitamin D Deficiency in Patients with Crohn's Disease: Pathological Conditions That Should Be Linked Together.

Sarcopenia is a prevalent condition in patients with Crohn's disease (CD), representing an independent predictor factor for the development of major postoperative complications. Thus, a proper assessment of the muscle strength, by using different validated tools, should be deemed an important step of the clinical management of these patients. Patients with CD are frequently malnourished, presenting a high prevalence of different macro- and micro-nutrient deficiencies, including that of vitamin D.

More than a "monstrous obesity"! Time to overcome the "anti-fat" bias.

A 54-years-old woman complained of unintentional important body weight gain associated with abdominal bloating. For this reason, she had consulted many different diet and nutritional professionals, general practitioners and a gastroenterology specialist, but no one went beyond a simple diagnosis of "monstrous obesity". At our hospital division, based on physical examination, a computed tomography (CT) of the abdomen and pelvis was performed.

The Analysis of Food Intake in Patients with Cirrhosis Waiting for Liver Transplantation: A Neglected Step in the Nutritional Assessment.

Patients with cirrhosis waiting for liver transplantation (LT) frequently present a nutritional disorder, which represents an independent predictor of morbidity and mortality before and after transplantation. Thus, a proper assessment of the food intake by using different methods, such as food records, food frequency questionnaires, and 24 h recall, should be deemed an important step of the nutritional management of these patients. The available published studies indicate that the daily food intake is inadequate in the majority of waitlisted patients.
