Modelling the long-term health impact of COVID-19 using Graphical Chain Models brief heading: long COVID prediction by graphical chain models.

Background: Long-term sequelae of SARS-CoV-2 infection, namely long COVID syndrome, affect about 10% of severe COVID-19 survivors. This condition includes several physical symptoms and objective measures of organ dysfunction resulting from a complex interaction between individual predisposing factors and the acute manifestation of disease. We aimed at describing the complexity of the relationship between long COVID symptoms and their predictors in a population of survivors of hospitalization for severe COVID-19-related pneumonia using a Graphical Chain Model (GCM).

Association between Mediterranean diet and dementia and Alzheimer disease: a systematic review with meta-analysis.

Background: Dementia affects 5-8% of the population aged over 65 years (~50 million worldwide). Several factors are associated with increased risk, including diet. The Mediterranean diet (MedDiet) has shown potential protective effects against several chronic diseases.

Exosomal miR-17-5p, miR-146a-3p, and miR-223-3p Correlate with Radiologic Sequelae in Survivors of COVID-19-Related Acute Respiratory Distress Syndrome.

We investigated the association between circulating microRNAs (miRNAs) potentially involved in the lung inflammatory process and fibrosis development among COVID-19-related acute respiratory distress syndrome (ARDS) survivors. At 4 ± 2 months from clinical recovery, COVID-19-related ARDS survivors matched for age, sex, and clinical characteristics underwent chest high-resolution computerized tomography (HRCT) and were selected based on imaging pattern evolution into fully recovered (N = normal), pulmonary opacities (PO) and fibrosis-like lesions (FL). Based on the previous literature, we performed plasma miRNA profiling of exosomal miRNAs belonging to the NLRP3-inflammasome platform with validated (miR-17-5p, miR-223-3p) and putative targets (miR-146a-5p), miRNAs involved in the post-transcriptional regulation of acute phase cytokines (miR128-3p, miR3168, miR125b-2-3p, miR106a-5p), miRNAs belonging to the NLRP4-inflammasome platform (miR-141-3p) and miRNAs related to post-transcriptional regulation of the fibrosis process (miR-21-5p).

Human immunoglobulins are transported to HCMV viral envelope by viral Fc gamma receptors-dependent and independent mechanisms.

Human cytomegaloviruses (HCMVs) employ many different mechanisms to escape and subvert the host immune system, including expression of the viral IgG Fcγ receptors (vFcγRs) (gp34), (gp95), (gpRL13), and (gp68) gene products. The role of vFcγRs in HCMV pathogenesis has been reported to operate in infected cells by interfering with IgG-mediated effector functions. We found that gp34 and gp68 are envelope proteins that bind and internalize human IgGs on the surface of infected cells.

Predictors of stigma in a sample of mental health professionals: Network and moderator analysis on gender, years of experience, personality traits, and levels of burnout.

Background: Stigma is one of the most important barriers to help-seeking and to personal recovery for people suffering from mental disorders. Stigmatizing attitudes are present among mental health professionals with negative effects on the quality of health care.

Methods: Network and moderator analysis were used to identify what path determines stigma, considering demographic and professional variables, personality traits, and burnout dimensions in a sample of mental health professionals (n = 318) from six Community Mental Health Services.

Characterization of pUL5, an HCMV protein interacting with the cellular protein IQGAP1.

Among the Herpesviridae, human cytomegalovirus (HCMV) owns the largest genome and displays a huge coding potential. Here, we characterized the UL5 gene product (pUL5) of the clinical isolate TR strain. The protein was predicted as a 166-amino-acid membrane protein with a theoretical mass of 19 kDa.

Lithium Exposure During Pregnancy and the Postpartum Period: A Systematic Review and Meta-Analysis of Safety and Efficacy Outcomes.

Objective: Uncertainty surrounds the risks of lithium use during pregnancy in women with bipolar disorder. The authors sought to provide a critical appraisal of the evidence related to the efficacy and safety of lithium treatment during the peripartum period, focusing on women with bipolar disorder and their offspring.

Methods: The authors conducted a systematic review and random-effects meta-analysis assessing case-control, cohort, and interventional studies reporting on the safety (primary outcome, any congenital anomaly) or efficacy (primary outcome, mood relapse prevention) of lithium treatment during pregnancy and the postpartum period.

Exploring the relationships among personality traits, burnout dimensions and stigma in a sample of mental health professionals.

A sample of mental health professionals (n = 215) from six Community Mental Health Services was examined using a short version of the Attribution Questionnaire-27, the Maslach Burnout Inventory and the Ten Items Personality Inventory to detect possible associations among stigma, burnout dimensions and personality traits. The role of demographic and professional variables was also explored. Perception of workplace safety resulted to significantly affect attitudes toward patients.

Sleep quality and duration is related with diet and obesity in young adolescent living in Sicily, Southern Italy.

The aim of this study was to evaluate the association between sleeping habits, Mediterranean diet pattern, and weight status in an adolescent population. The sample consisted of 1586 individuals aged 11-14 years attending 15 secondary schools of Sicily, Southern Italy. School were randomly selected and the data collected during two school years.

Personal eating, lifestyle, and family-related behaviors correlate with fruit and vegetable consumption in adolescents living in sicily, southern Italy.

Lifestyle habits and parental modeling have been reported to influence adolescents’ food choices, such as for fruit and vegetable consumption. The aim of this study was to investigate the association be-tween personal eating (i. e.

Evaluation of four comorbidity indices and Charlson comorbidity index adjustment for colorectal cancer patients.

Introduction: Cancer survival is related not only to primary malignancy but also to concomitant nonmalignant diseases. The aim of this study was to investigate the prognostic capacity of four comorbidity indices [the Charlson comorbidity index (CCI), the Elixhauser method, the National Institute on Aging (NIA) and National Cancer Institute (NCI) comorbidity index, and the Adult Comorbidity Evaluation-27 (ACE-27)] for both cancer-related and all-cause mortality among colorectal cancer patients. A modified version of the CCI adapted for colorectal cancer patients was also built.

Long-term persistence of seroprotection by hepatitis B vaccination in healthcare workers of southern Italy.

Background: The impact of hepatitis B virus (HBV) vaccination campaigns on HBV epidemiology needs to be evaluated, in order to assess the long-term immunity offered by vaccines against HBV.

Objectives: To evaluate the current status of anti-HBV vaccine coverage among healthcare workers (HCWs) in Southern Italy, and to determine the long-term persistence of antibodies to hepatitis B surface antigens (anti-HBs) in such a cohort of subjects.

Patients And Methods: A longitudinal, retrospective seroepidemiological survey was conducted among 451 HCWs, who were working at or visiting, the Occupational Health Department of a city hospital, in Catania, Italy, between January 1976 and December 2010.

Pattern of antibiotic use in the community: νon-adherence and self-prescription rates in an Italian urban population.

The aim of the present study was to assess the pattern of antibiotic use in a community setting of an urban area of Italy and identify factors that affect adherence to their use. By using a questionnaire-based survey, we collected 1,269 interviews and performed analysis on those patients who had their last course of antibiotic within the past 12 months (956 subjects). Among the subjects reporting that they had not followed their last antibiotic course as prescribed, 14.

Ischemic preconditioning requires increases in reactive oxygen release independent of mitochondrial K+ channel activity.

Mitochondrial ATP-sensitive K+ channels (mitoKATP) mediate ischemic preconditioning, a cardioprotective procedure. MitoKATP activity has been proposed to either enhance or prevent the release of reactive oxygen species. This study tested the redox effects of mitoKATP in order to clarify the role of these channels during preconditioning.

Mitochondrial ATP-sensitive K+ channel opening decreases reactive oxygen species generation.

Mitochondrial ATP-sensitive K(+) channel (mitoK(ATP)) opening was shown previously to slightly increase respiration and decrease the membrane potential by stimulating K(+) cycling across the inner membrane. Here we show that mitoK(ATP) opening reduces reactive oxygen species generation in heart, liver and brain mitochondria. Decreased H(2)O(2) release is observed when mitoK(ATP) is active both with respiration stimulated by oxidative phosphorylation and when ATP synthesis is inhibited.

Anterior shoulder dislocation and injuries of the rotator cuff in patients aged over 40 years. Clinical and sonographic study.

A total of 39 patients with a mean age of 64 years (41 to 88) who had had anterior shoulder dislocation were followed-up an average of 2 years after trauma in order to evaluate the conditions of the rotator cuff. All of the patients were evaluated clinically, radiographically, and sonographically. Clinical evaluation revealed significant differences between the dislocated shoulders and the contralateral ones: the mean Constant score was 67 in the group with dislocated shoulders and 87 in the contralateral group.

Circulating dendritic cells in early and advanced cancer patients: diminished percent in the metastatic disease.

Despite the well demonstrated fundamental role of dendritic cells (DC) in generating antitumor immunity in experimental conditions, to date there are only few preliminary studies which investigate the percent of DC in the peripheral blood of cancer patients. Several cell surface markers have now been described which are specific to cultured DC, however their expression in vivo is still controversial. Recently, however, two DC subsets, consisting of immature and mature DC, have been shown to be present in peripheral blood, which can be recognized as CD123+ and CD11c+ cells, respectively.

Daytime oxygen saturation does not predict nocturnal oxygen desaturation in patients with chronic obstructive pulmonary disease.

Nocturnal hypoxemia occurs commonly in patients with chronic obstructive pulmonary disease (COPD). Because pulmonary hypertension and cardiac arrhythmias are associated with this phenomenon, the detection and treatment of nocturnal hypoxemia should be part of the management of COPD patients. The ability to predict nocturnal hypoxemia by evaluating an awake patient would be desirable economically and logistically because continuous nocturnal oximetry is not widely available and because it is costly and labor intensive.

Incidence and nature of dysphagia in polio survivors.

Questionnaires pertaining to swallowing function were mailed to 220 members of postpolio support groups in Connecticut. Of the 109 responses, 80 individuals reported having no difficulty with swallowing, while 29 reported having either intermittent or consistent swallowing problems. Twenty-one of the 29 were seen for videofluoroscopic swallowing studies and pulmonary function testing.

Nutrition for the respiratory insufficient patient.

Malnutrition is fairly common in patients with chronic obstructive pulmonary disease, the more severe the airway obstruction the more severe the nutritional status. The consequences of nutritional depletion on respiratory and immune systems are ventilatory compromise and susceptibility to infection. Diaphragm muscle mass and thickness is decreased in patients with COPD.

Weaning from mechanical ventilation: adjunctive use of inspiratory muscle resistive training.

We used inspiratory resistive training (IRT) in an effort to improve the respiratory muscle endurance of 27 patients with respiratory failure who had failed repeated weaning attempts using standard techniques. Seven patients had primary neuromuscular diseases; the other 20 had primary lung diseases. All patients had stable respiratory failure, without gross malnutrition or electrolyte disorders.

Bilateral diaphragmatic paralysis: clinical spectrum, prognosis, and diagnostic approach.

In a retrospective review of the clinical course of five patients with nontrauma-related bilateral diaphragmatic paralysis, we found that the diagnosis is generally delayed (median delay: two years) in the presence of moderate to severe respiratory insufficiencies. Orthopnea out of proportion to the underlying cardiopulmonary status and thoracoabdominal paradoxus in the supine position are the clues to the diagnosis. Pulmonary function tests showed a typical restrictive ventilatory defect, and arterial blood gas showed chronic respiratory acidosis.

Diaphragmatic dysfunction in siblings with hereditary motor and sensory neuropathy (Charcot-Marie-Tooth disease).

Hereditary motor and sensory neuropathy (Charcot-Marie-Tooth disease) is characterized by chronic degeneration of peripheral nerves and roots, resulting in distal muscle atrophy, beginning in the feet and legs and later involving the hands. The association of this disease with diaphragmatic dysfunction has not been reported. We studied a patient with hereditary motor and sensory neuropathy type 1 (Charcot-Marie-Tooth disease) and type 2 diabetes mellitus who had severe diaphragmatic impairment.

Further specification and evaluation of a new clinical index for dyspnea.

When breathlessness is described in conventional clinical indexes-such as the Pneumoconiosis Research Unit score or the Medical Research Council index-the ratings depend only on the magnitude of the most taxing task that the patient can perform. No attention is given to the patient's effort in performing tasks or to the functional impairment produced by dyspnea in everyday activities. To improve the effectiveness and scope of the assessment, the patient's magnitude of effort and task, as well as functional impairment, were combined in a recently developed new index of dyspnea.
