Colorectal cancer screening: The surgery rates they are a-changing. A nationwide study on surgical resections in Italy

Background

Growing evidence suggests that colorectal cancer (CRC) screening based on the fecal immunochemical test (FIT) reduces CRC incidence and surgical resection rates.

The diagnostic yield of colonoscopy in hospitalized patients. An observational multicenter prospective study.

BackgroundColonoscopy demands a considerable amount of resources, and little is known about its diagnostic yield among inpatients.AimsTo assess indications, diagnostic yield and findings of colonoscopy for inpatients, and to identify risk factors for relevant findings and cancer.MethodsMulticentre, prospective, observational study including 12 hospitals. Consecutive adult inpatients undergoing colonoscopy were evaluated from February through November 2019.Results1,302 inpatients underwent colonoscopy. Diagnostic yield for relevant findings and cancer was 586 (45%) and 112 (8.6%), respectively. Adequate colon cleansing was achieved in 896 (68.8%) patients. Split-dose/same-day regimen was adopted in 847 (65%) patients. Factors associated to relevant findings were age ≥70 years (RR 1.32), male gender (RR 1.11), blood loss (RR 1.22) and adequate cleansing (RR 1.63). Age ≥70 years (RR 2.08), no previous colonoscopy (RR 2.69) and split-dose/same-day regimen (RR 1.59) significantly increased cancer detection. Implementing adequate cleansing and split-dose/same-day regimen in all patients would increase the diagnostic yield for any relevant findings and cancer from 43% to 70% and from 6% to 10%, respectively.ConclusionRelevant colorectal diseases and cancer were frequent among inpatients. Factors associated with detection of relevant findings were identified. Adequate colon cleansing and split-dose/same-day regimen significantly increased colonoscopy diagnostic yield.     

Patients with a history of stable or unstable coronary heart disease have different acute phase responses to an inflammatory stimulus

Increased levels of acute phase proteins (APP) in serum are associated with vulnerability of atherosclerotic plaques and acute manifestations of coronary heart disease (CHD). APP have been viewed as indexes of active vascular inflammation or as mediators of atherothrombosis. In the present study we tested the hypothesis that individuals who develop stable or unstable forms of CHD might have different innate responses to an inflammatory stimulus. We compared changes in plasma C-reactive protein (CRP) and serum amyloid A (SAA) concentrations 48 h after a standardized inflammatory stimulus (adjuvanted influenza vaccination) in patients with quiescent CHD that had been manifested at onset as inducible myocardial ischemia (Group 1, n=26) or as acute coronary syndromes (ACS) (Group 2, n=34). Selected patients were free from inflammatory or other conditions that might affect the immune response. CRP concentration increased significantly after vaccination in both groups (Group 1: 0.47 [0.21-0.86] to 0.56 [0.32-1.17]mg/L, p=0.005; Group 2: 0.64 [0.21-1.09] to 0.75 [0.33-1.48]mg/L, p=0.003), without significant differences between groups in absolute or percentage changes. By contrast, SAA did not change after vaccination in Group 1 (14.4 [8.9-19.5] to 14.8 [10.3-18.8]mg/L, p=0.88) but increased significantly in Group 2 (16.9 [10.0-21.5] to 19.2 [11.3-29.1]mg/L, p=0.002), with significant differences between the groups in absolute and percentage terms (p=0.015 and 0.019, respectively). Changes in CRP and SAA, both absolute and percentage, were significantly correlated in Group 2 (r=0.60 and 0.66, both p<0.001). The responsiveness of plasma SAA to an inflammatory stimulus in Group 2 alone suggests a pro-inflammatory status in patients prone to acute coronary syndrome but not in those with inducible myocardial ischemia.     

Clinical spectrum and outcomes in families with coronal synostosis and TCF12 mutations

TCF12 mutations have been reported very recently in coronal synostosis. We report several cases of familial coronal synostosis among four families harbouring novel TCF12 mutations. We observed a broad interfamilial phenotypic spectrum with features overlapping with the Saethre–Chotzen syndrome. TCF12 molecular testing should be considered in patients with unilateral- or bilateral-coronal synostosis associated or not with syndactyly, after having excluded mutations in the TWIST1 gene and the p.Pro250Arg mutation in FGFR3.     

Intervertebral disc degeneration: A focus on obesity and type 2 diabetes

Obesity (OB) and type 2 diabetes (T2D) are among the most prevalent metabolic diseases. They currently affect a substantial part of the world population and are characterized by several systemic co‐morbidities, including cardiovascular diseases, stroke, cancer, liver steatosis, and musculoskeletal disorders, by increasing the risk of developing osteoarthritis and intervertebral disc degeneration (IVDD). IVDD is a chronic, progressive process whose main features are disc dehydration, loss of disc height, and changes of load distribution across the spine, resulting in disc structure disruption and leading to low back pain onset. Given the high prevalence of these metabolic disorders and their association with IVDD, several studies have been conducted in order to investigate the causative role of biological and biomechanical characteristics proper to these conditions in the development of IVDD. This review aims to analyse the role of OB and T2D on IVDD, in order to clarify the pathophysiological drivers of the degenerative process and to delineate possible targets to which appropriate treatments may be addressed in the near future.     

Glucose metabolism transporters and epilepsy: Only GLUT1 has an established role

The availability of glucose, and its glycolytic product lactate, for cerebral energy metabolism is regulated by specific brain transporters. Inadequate energy delivery leads to neurologic impairment. Haploinsufficiency of the glucose transporter GLUT1 causes a characteristic early onset encephalopathy, and has recently emerged as an important cause of a variety of childhood or later‐onset generalized epilepsies and paroxysmal exercise‐induced dyskinesia. We explored whether mutations in the genes encoding the other major glucose (GLUT3) or lactate (MCT1/2/3/4) transporters involved in cerebral energy metabolism also cause generalized epilepsies. A cohort of 119 cases with myoclonic astatic epilepsy or early onset absence epilepsy was screened for nucleotide variants in these five candidate genes. No epilepsy‐causing mutations were identified, indicating that of the major energetic fuel transporters in the brain, only GLUT1 is clearly associated with generalized epilepsy.     

Clinique des psychoses et théorisation du désarroi

The psychotic states occupy a particular position (?) within the psychoanalytical theorization. They set a major resistance against their treatment so clinical as theoretical arousing movements of profound disarray at the clinicians. The part counter-transference (?) of the process of theorization aroused by the psychotherapy of the psychotic states engenders a particular shape of elaboration, an conceptual higher bid which plays the role of “theoretical reprisals” in front of the narcissistic wound imposed by these problems. These “theoretical reprisals” represent an attempt of connection of the psychic processes in failure and fix the limits of the models of understanding. This necessary stage of the work of conceptualization can be exceeded by return on the clinical practices allowing the subjective appropriation of the theorized notions.
