Inflammatory bowel diseases (IBDs) often present as a complex inflammatory process wherein colon lesions (ulcerative colitis, UC) or widespread ulceration and fissure (Crohn's disease, CD) might be accompanied by ancillary extraintestinal manifestations (EIMs) that could involve almost every organ system, but also by autoimmune disorders ranging from psoriasis and rheumatoid arthritis to connective tissue diseases. Certain EIMs are more common related to the activity of the IBD (joint, skin, ocular and oral manifestations), other EIMs typically run a course independent of the IBD activity (hepatobiliary disorders) and some are non-specific disorders (osteoporosis and amyloidosis). ⋯ Thus, early recognition of these manifestations should help guide therapy that will reduce overall morbidity in affected patients. Key Message A complete review on the most common extraintestinal and rheumatologic manifestations of ulcerative colitis and Crohn's disease.

Few studies investigated the combined effects of night-shift work, daytime napping, and nighttime sleep on cancer incidence and mortality. ⋯ Long night-shift work history, without daytime napping, and long nighttime sleep duration were independently and jointly associated with higher cancer incidence among males. KEY MESSAGES Night-shift work of ≥20 years, without napping, and nighttime sleep of ≥10 h were associated with increased cancer incidence. Nighttime sleep ≥10 h was associated with a 2.07-fold increased cancer-caused mortality among males. Combined effects of night-shift work ≥20 years, without napping, and nighttime sleep ≥10 h on increasing cancer incidence were existed among males.

Podoplanin is a cell-surface glycoprotein constitutively expressed in the brain and implicated in human brain tumorigenesis. The intrinsic function of podoplanin in brain neurons remains however uncharacterized. ⋯ This work proposes podoplanin as a novel component of the neuronal machinery underlying neuritogenesis, synaptic plasticity, and hippocampus-dependent memory functions. The existence of a relevant cross-talk between podoplanin and the NGF/TrkA signaling pathway is also for the first time proposed here, thus providing a novel molecular complex as a target for future multidisciplinary studies of the brain function in the physiology and the pathology. Key messages Podoplanin, a protein linked to the promotion of human brain tumors, is required in vivo for proper hippocampus-dependent learning and memory functions. Deletion of podoplanin selectively impairs activity-dependent synaptic strengthening at the neurogenic dentate-gyrus and hampers neuritogenesis and phospho Ezrin, TrkA and CREB protein levels upon NGF stimulation. Surface plasmon resonance data indicates a physical interaction between podoplanin and NGF. On these grounds, a relevant cross-talk between podoplanin and NGF as well as a role for podoplanin in plasticity-related brain neuronal functions is here proposed.

Hypertrophic cardiomyopathy (HCM) is the most common inherited heart disease, with the prevalence of about 1/500. During the last two decades, the knowledge of the etiology, pathogenesis, risk stratification and prevention of sudden death in HCM has substantially advanced. Most often, HCM is familial and caused by mutations in sarcomere genes, inherited in an autosomal dominant manner. ⋯ Key messages Hypertrophic cardiomyopathy, most often caused by defects in sarcomere genes, is the most common inherited heart disease, and a common cause of sudden cardiac death (SCD) in athletes and young subjects. Cardiac imaging, ECG and genetic testing are pivotal in the diagnosis of the disease in patients and first-degree relatives. Implantable cardioverter defibrillators in patients with high risk for SCD and tailored pharmacotherapy are efficient tools in patient care, but so far, exact mechanisms leading to cardiac hypertrophy in HCM are only partially understood, and there is no curative treatment for the disease.

Interventions directed to individuals by health and social care systems should increase health and welfare of patients and customers. ⋯ CIR should be given a high priority in medical, health care, and health economic research. Clinicians and leaders at all levels of health care can exploit the evidence from CIR. Key messages The new concept of Clinical Impact Research (CIR) is defined as a research field aiming to assess what are the impacts of healthcare and public health interventions targeted to patients or individuals. The term impact refers to all effects caused by the interventions, with particular emphasis on accessibility, quality, equality, effectiveness, safety, and efficiency. CIR uses two study designs: randomized controlled trials (RCTs) (experimental) and benchmarking controlled trials (BCTs) (observational). Suggestions on how to choose between RCT and BCT as the most suitable study design are presented. Simple way of determining the study question in CIR based on the PICO (patient, intervention, control intervention, outcome) framework is presented. CIR creates the scientific basis for clinical decisions. Clinicians and leaders at all levels of health care and those working for public health can use the evidence from CIR for the benefit of patients and the population.
