REVIEW
Mia Beck Lichtenstein, Cecilie Juul Hinze, Bolette Emborg, Freja Thomsen, Simone Daugaard Hemmingsen
Compulsive exercise is a condition described since 1970s. It is characterized by a craving for physical training, resulting in uncontrollable excessive exercise behavior with harmful consequences, such as injuries and impaired social relations. It has not been accepted as a mental disorder in either International Classification of Diseases or Diagnostic and Statistical Manual of Mental Disorders. The aim of this literature review was to critically examine the research on links (comorbidity), risks (negative consequences), and challenges faced (problems in a treatment context)...

A new quill mite species of the family Syringophilidae (Acariformes: Prostigmata: Cheyletoidea) is described from Phimosus infuscatus (Lichtenstein) (Pelecaniformes: Threskiornithidae) in Argentina. Selenonycha insperata n. sp. differs from other species of the genus Selenonycha Kethley, 1970 by the presence of wing-like cuticular projections of coxal fields III-IV situated in front of trochanters (vs absence). An unexpected finding of this species on a bird of the family Threskiornithidae (Pelecaniformes) is discussed as an example of host shift...

BACKGROUND: Colorectal cancer (CRC) is the second leading cause of cancer-related mortality in the United States. There is an increasing need for the identification of biomarkers of pre-malignant and early stage CRC to improve risk-stratification and screening recommendations. In this study, we investigated the possibility of metabolic and mitochondrial reprogramming early in the pre-malignant colorectal field. METHODS: Rectal biopsies were taken from 81 patients undergoing screening colonoscopy, and gene expression of metabolic and mitochondrial markers were assessed using real time quantitative PCR...

Rationale Associations between fetal growth restriction and lung function impairment could be due to gestational age, shared (familial) genetic and environmental factors. Objectives To study the association between fetal growth and lung function in childhood, while taking gestational age and familial factors into account. Methods Firstly, full cohort analyses of twins were performed to study the association between birth weight, gestational age and fetal growth and lung function (forced expiratory volume in first second (FEV1), forced vital capacity (FVC) and FEV1/FVC) in z-scores before (n=520) and after (n=539) bronchodilator treatment...

BACKGROUND: The aim of this study was to investigate the reoperation rates after open indirect inguinal hernia repair with and without mesh in young males and other age groups. Younger males have higher risk of developing chronic pain after open inguinal hernia repair with mesh compared with older patients. Avoiding mesh among younger patients could be justified, if they have an acceptable low risk of recurrence compared with other groups and compared with Lichtenstein repair. METHODS: Data were extracted from the nationwide Danish Hernia Database which is recording prospectively...

Importance: Individuals who self-harm may have an increased risk of aggression toward others, but this association has been insufficiently investigated. More conclusive evidence may affect assessment, treatment interventions, and clinical guidelines. Objective: To investigate the association between nonfatal self-harm and violent crime. Design, Setting, and Participants: This population-based longitudinal cohort study, conducted from January 1, 1997, through December 31, 2013, studied all Swedish citizens born between 1982 and 1998 who were 15 years and older (N = 1 850 252)...

The intercellular spreading of protein assemblies is a major factor in the progression of neurodegenerative disorders. The quantitative study and visualization of cell-to-cell propagation using tagged-proteins is challenging due to the steric effect of relatively large fluorescence tags and the risk of 'false positive' identification when analyzing these rare transmission events. Here, we established a cell culture model to characterize the cell-to-cell transmission of TAR DNA-binding protein and α-synuclein, involved in amyotrophic lateral sclerosis and Parkinson's disease, respectively, using the small nine amino acid influenza hemagglutinin tag...

BACKGROUND: Understanding cardiac mechanics is important for developing cardiac therapies. Current modalities for assessing cardiac mechanics sample patient's heart at specific heart rate, contractility, preload, and afterload. The objective of this study was to test the feasibility of a novel system composed of intra-cardiac leads equipped with an inertial module chip (3D accelerometers and 3D gyroscopes) in monitoring continuous heart motion. METHODS: In this descriptive study, four healthy pigs were anesthetized and instrumented with motion-sensitive intra-cardiac leads; the temporal correlation between signals from motion sensors and tissue Doppler from the chest wall were studied; changes in real-time heart accelerations (ACC) and angular velocity (ANGV) were reported as percentages of change from baseline...

Adverse perinatal events may increase the risk of Tourette's and chronic tic disorders (TD/CTD), but previous studies have been unable to control for unmeasured environmental and genetic confounding. We aimed to prospectively investigate potential perinatal risk factors for TD/CTD, taking unmeasured factors shared between full siblings into account. A population-based birth cohort, consisting of all singletons born in Sweden in 1973-2003, was followed until December 2013. A total of 3 026 861 individuals were identified, 5597 of which had a registered TD/CTD diagnosis...

BACKGROUND: Corticosteroid (CS) use is an important marker of poor prognosis in ulcerative colitis (UC). Our aim was to develop and validate a model to predict the risk of CS utilization over the course of disease in newly diagnosed patients with UC. METHODS: Newly diagnosed patients with UC from a nationwide VA cohort were followed over time to evaluate factors predictive of CS use. Multivariate logistic regression was performed. Model development was performed in a random 2/3 of the total cohort and then validated in the remaining 1/3...

COMMENT
A V Lichtenstein
The opinion is presented according to which the "bad luck" hypothesis (Tomasetti, C., and Vogelstein, B. (2015) Science, 347, 78-81), which has recently received experimental confirmation, has the right to exist, and its criticisms are largely unfounded.

Arguments supporting the "bad luck" hypothesis presented by C. Tomasetti and B. Vogelstein ((2015) Science, 347, 78-81) and A. V. Lichtenstein ((2017) Biochemistry (Moscow), 82, 75-80) are critically discussed. Those arguments are not sufficient for recognition of the "bad luck" hypothesis and the leading role of internal factors in spontaneous tumor development.

REVIEW
A V Lichtenstein
Contrasting opinions on the role of extrinsic and intrinsic factors in cancer etiology (Tomasetti, C., and Vogelstein, B. (2015) Science, 347, 78-81; Wu, S., et al. (2016) Nature, 529, 43-47) variously define priorities in the war on cancer. The correlation between the lifetime risk of several types of cancer and the total number of divisions of normal self-renewing cells revealed by the authors has given them grounds to put forward the "bad luck" hypothesis. It assumes that ~70% of cancer variability is attributed to random errors arising during DNA replication in normal, noncancerous stem cells, i...

BACKGROUND: Autism spectrum disorders (ASD) are persistent and lifelong conditions. Despite this, almost all twin studies focus on childhood. This twin study investigated the stability of autistic traits from childhood to early adulthood and explored the degree to which any stability could be explained by genetic or environmental factors. METHODS: Parents of over 2500 twin pairs completed questionnaires assessing autistic traits when twins were aged either 9 or 12 years and again when twins were aged 18...

Lichtenstein hernioplasty is the number one technique worldwide for open, mesh-based inguinal hernia repair. The principle of Lichtenstein hernioplasty is the tension-free reinforcement of the abdominal wall by covering the transversalis fascia and the oblique muscles with an artificial patch of mesh. The Lichtenstein technique has been modified since its inception. The technique has the benefits of low costs and a rapid learning curve and can be performed with the patient under local anesthesia. The recurrence rates after the Lichtenstein operation are significantly lower compared to open suture repair and equal to laparoendoscopic techniques...
