The major advantages of primary prevention of colorectal cancer in young adults (around 20 years) compared with se condary prevention in adults (after 50 years). Primary prevention is aimed at screening and eliminating one of the major proven risk factors for colon cancer – chronic constipation and its predecessor – colorectal bradyarrhythmia – as slower circadian rhythm of defecation. The main advantages of primary prevention of colorectal cancer are: non-invasiveness, safety, efficiency and timeliness. Screening of colorectal bradyarrhythmia at 2501 operating physician is allowed to diagnose this arrhythmia in 44% of the surveyed entities. There is discovered the new fundamental dependence between the regularity of circadian rhythm of defecation and an acrophase of this rhythm. The implementation of the morning acrophase of the circadian rhythm of defecation is the key mechanism of the regularity of this rhythm. Repeated screening of colorectal bradyarrhythmia in individuals around the age of 20 years (a month after informing students about the law of circadian rhythm in the brain and intestine) showed that 53% of the students began to observe the morning routine of bowel movements. This led to a transition of moderate stage of colorectal bradyarrhythmia severity (3-4 times a week) in an easy stage (5-6 times a week). It’s proved the possibility of primary (behavioral) prevention of colorectal bradyarrhythmia (colorectal coprostasis) as a risk factor for colorectal cancer. Secondary prevention of colon cancer is associated with the invasiveness of colonoscopy, its possible complications (bleeding, perforation of bowel and fatal outcomes), the high cost of special equipment and late in the approach to screening for colorectal cancer (after the appearance of blood in the stool or after 50 years).

Objective. A shift in the total incidence from left- to right-sided colon cancer has been reported and raises the question as to whether lifestyle risk factors are responsible for the changing subsite distribution of colon cancer. The present study provides a review of the subsite-specific risk estimates for the dietary components presently regarded as convincing or probable risk factors for colorectal cancer: red meat, processed meat, fiber, garlic, milk, calcium, and alcohol.Methods. Studies were identified by searching PubMed through October 8, 2012 and by reviewing reference lists. Thirty-two prospective cohort studies are included, and the estimates are compared by sex for each risk factor.Results. For alcohol, there seems to be a stronger association with rectal cancer than with colon cancer, and for meat a somewhat stronger association with distal colon and rectal cancer, relative to proximal colon cancer. For fiber, milk, and calcium, there were only minor differences in relative risk across subsites. No statement could be given regarding garlic. Overall, many of the subsite-specific risk estimates were nonsignificant, irrespective of exposure.Conclusion. For some dietary components the associations with risk of cancer of the rectum and distal colon appear stronger than for proximal colon, but not for all.

Background: Tetralogy of Fallot (TOF) is the most frequent form of congenital heart disease managed by EP physicians for potential ICD. However, few studies have reported long-term outcomes of TOF patients with ICD. Methods: Between 2005 and 2014, all TOF patients with ICD in 17 French centers were enrolled in a specific evaluation aiming to determine characteristics at implantation as well as outcomes (overall mortality, appropriate ICD therapies, and device-related complications). Results: Overall 78 patients (45±13 years, 64% males) were enrolled. A majority of patients were implanted in the setting of secondary prevention (73%), whereas the remaining (27%) in primary prevention. Among the latest group, known risk factors for sudden cardiac death were: severe pulmonary regurgitation (30%,) prior palliative shunt (50%), syncope with unknown origin (25%), inducible ventricular tachycardia (45%), QRS duration ≥180ms (18%), non-sustained ventricular tachycardia (25%), and documented sustained supra ventricular tachycardia (45%).Overall, patients implanted in the setting of primary prevention presented with a mean of 3.1±1.4 risk factors. After a mean follow-up of 4.9±3.8 years, 35 patients (45%) experienced at least one appropriate therapy (25% in the primary prevention group compared to 53% in the secondary prevention group), giving annual-incidences of 6.9% (95%CI 0.14-13.7) and 21.3% (12.4-30.3) respectively (P=0,01). The mean time between ICD implantation and the first appropriate therapy was 2.2±3.2 years, without significant differences between primary and secondary prevention. Overall, ≥one ICD-related complication occurred in 30 patients (38%), including inappropriate shock (n=9), major pocket hematoma (n=1), lead dysfunction (n=12), infection (n=4), shoulder algodystrophia (n=2), device failure or dislodgement needing reintervention (n=2). Eventually, four patients were transplanted (5%), and six patients (8%) died during the course of follow-up. Conclusions: Considering relatively long-term follow-up, patients with TOF and ICDs experience high rates of appropriate ICD therapies, in both primary and secondary prevention. Major ICD-related complications remain, however, high.

Introduction: Hypertrophic cardiomyopathy (HCM) is a leading cause of sudden cardiac death (SCD) in young adults. Implantable cardioverter defibrillators (ICD) effectively terminate ventricular tachycardia (VT) and fibrillation (VF) that cause SCD, but the reported prevalence of and patient characteristics leading to appropriate ICD therapy in HCM have been variable. Hypothesis: We hypothesized that some risk factors may be more prevalent than others in patients with HCM who receive appropriate ICD therapy and that the overall incidence of appropriate therapy may be lower than that reported previously. Methods: We retrospectively studied all patients with HCM who were treated with ICDs at our referral center from 2000-2013 to determine the rates of appropriate and inappropriate ICD therapies. Results: Of 1136 patients with HCM, we identified 135 who underwent ICD implantation (125 for primary and 10 for secondary prevention), aged 18-81 years (mean 48±17) at the time of implantation. The mean follow-up time was 5.2±4.5 years. Appropriate ICD intervention occurred in 20 of 135 patients (2.8%/year) by providing a shock or antitachycardia pacing in response to VT or VF. The annual rate of appropriate ICD therapy was 2.4%/year for primary and 7.2%/year for secondary prevention devices. Commonly used risk factors were equally prevalent among patients who received appropriate therapy and those who did not; furthermore, the likelihood of receiving appropriate therapy in the presence of each risk factor was similar (Figure). Inappropriate ICD therapy occurred in 27 patients (3.8%/year). Conclusions: ICDs provide clear benefit to patients who experience life-threatening arrhythmias, particularly those being treated for secondary prevention. However, the appropriate therapy rate for primary prevention was lower than previously reported, and no single risk factor appeared to have stronger association with appropriate ICD therapy than others.

Abstract Antiphospholipid syndrome (APS) is an acquired autoimmune condition characterized by thrombotic events, pregnancy morbidity, and laboratory evidence of antiphospholipid antibodies (aPL). Management of these patients includes the prevention of a first thrombotic episode in at-risk patients (primary prevention) and preventing recurrent thrombotic complications in patients with a history of thrombosis (secondary prevention). Assessment of thrombotic risk in these patients, balanced against estimated bleeding risks associated with antithrombotic therapy could assist clinicians in determining whether antithrombotic therapy is warranted. Thrombotic risk can be assessed by evaluating a patient’s aPL profile and additional thrombotic risk factors. Although antithrombotic options for secondary prevention of venous thromboembolism (VTE) have been evaluated in clinical trials, studies in primary prevention of asymptomatic aPL-positive patients are needed. Primary prevention with aspirin may be considered in asymptomatic patients who have a high-risk aPL profile, particularly if additional risk factors are present. Secondary prevention with long-term anticoagulation is recommended based on estimated risks of VTE recurrence, although routine evaluation of thrombotic risk can assist in determining whether ongoing anticoagulation is warranted. Studies that stratify thrombotic risk in aPL-positive patients, and patients with APS evaluating antithrombotic and non-antithrombotic therapies will be useful in optimizing the management of these patients.

Introduction Cancer is a worldwide problem as it will affect one in three men and one in four women during their lifetime. Colorectal cancer (CRC) is the third most frequent cancer in men, after lung and prostate cancer, and is the second most frequent cancer in women after breast cancer. It is also the third cause of death in men and women separately, and is the second most frequent cause of death by cancer if both genders are considered together. CRC represents approximately 10% of deaths by cancer. Modifiable risk factors of CRC include smoking, physical inactivity, being overweight and obesity, eating processed meat, and drinking alcohol excessively. CRC screening programs are possible only in economically developed countries. However, attention should be paid in the future to geographical areas with ageing populations and a western lifestyle. 19 , 20 Sigmoidoscopy screening done with people aged 55-64 years has been demonstrated to reduce the incidence of CRC by 33% and mortality by CRC by 43%. Objective To assess the effect on the incidence and mortality of CRC diet and lifestyle and to determine the effect of secondary prevention through early diagnosis of CRC. Methodology A comprehensive search of Medline and Pubmed articles related to primary and secondary prevention of CRC and subsequently, a meta-analysis of the same blocks are performed. Results 225 articles related to primary or secondary prevention of CRC were retrieved. Of these 145 were considered valid on meta-analysis: 12 on epidemiology, 56 on diet and lifestyle, and over 77 different screenings for early detection of CRC. Cancer is a worldwide problem as it will affect one in three men and one in four women during their lifetime. There is no doubt whatsoever which environmental factors, probably diet, may account for these cancer rates. Excessive alcohol consumption and cholesterol-rich diet are associated with a high risk of colon cancer. A diet poor in folic acid and vitamin B6 is also associated with a higher risk of developing colon cancer with an overexpression of p53. Eating pulses at least three times a week lowers the risk of developing colon cancer by 33%, after eating less meat, while eating brown rice at least once a week cuts the risk of CRC by 40%. These associations suggest a dose–response effect. Frequently eating cooked green vegetables, nuts, dried fruit, pulses, and brown rice has been associated with a lower risk of colorectal polyps. High calcium intake offers a protector effect against distal colon and rectal tumors as compared with the proximal colon. Higher intake of dairy products and calcium reduces the risk of colon cancer. Taking an aspirin (ASA) regularly after being diagnosed with colon cancer is associated with less risk of dying from this cancer, especially among people who have tumors with COX-2 overexpression. 16 Nonetheless, these data do not contradict the data obtained on a possible genetic predisposition, even in sporadic or non-hereditary CRC. CRC is susceptible to screening because it is a serious health problem given its high incidence and its associated high morbidity/mortality. Conclusions (1) Cancer is a worldwide problem. (2) A modification of diet and lifestyle could reduce morbidity and mortality. (3) Early detection through screening improves prognosis and reduces mortality.

Molecular Crosstalk

Chronic stress is thought to be involved in the occurrence and progression of multiple diseases, via mechanisms that still remain largely unknown. Interestingly, key regulators of the stress response, such as members of the corticotropin-releasing-hormone (CRH) family of neuropeptides and receptors, are now known to be implicated in the regulation of chronic inflammation, one of the predisposing factors for oncogenesis and disease progression. However, an interrelationship between stress, inflammation, and malignancy, at least at the molecular level, still remains unclear. Here, we attempt to summarize the current knowledge that supports the inseparable link between chronic stress, inflammation, and colorectal cancer (CRC), by modulation of a cascade of molecular signaling pathways, which are under the regulation of CRH-family members expressed in the brain and periphery. The understanding of the molecular basis of the link among these processes may provide a step forward towards personalized medicine in terms of CRC diagnosis, prognosis and therapeutic targeting.

Bevacizumab is an important component in the treatment of metastatic colorectal cancer when used with 5-fluorouracil, leucovorin and oxaliplatin or irinotecan. As a molecular target agent, it is considered to be less toxic than traditional chemotherapy; however, bevacizumab has been shown to cause serious, life-threatening adverse effects. The following report describes a case of bevacizumab-associated pulmonary embolism with simultaneous gastrointestinal perforation in a patient with stage IV adenocarcinoma of the descending colon. This case report and literature review describes the risk factors, etiology, and typical presentation of bevacizumab-induced gastrointestinal perforation and pulmonary embolism.

Epidemiological research into schizophrenia has a long and productive history over many decades, since the formulation of the disease concept by Emil Kraepelin in 1896. As a critical counterpart to clinical and biological research, its focus is on the population frequency and distribution of incidence, prevalence, course, and outcome, and the associated risk factors. This chapter presents an overview of the historical landmarks of the epidemiology of schizophrenia, its progress over the years, and the state of current knowledge. It highlights the challenges for its future directions of this research, including the question of whether primary or secondary prevention of the disorder will eventually be possible. The unprecedented growth of basic knowledge about the brain and the human genome opens up novel perspectives in the study of complex disorders, such as schizophrenia, which integrate concepts and tools of genetics, neuroscience, and epidemiology.

Objective: Identify the extent of statin use for primary prevention of macrovascular complications, the extent of statin or gemfibrozil use for the secondary prevention of cardiovascular morbidity and mortality, and the statin doses used in patients with type 2 diabetes and other cardiovascular risk factors.Design: Retrospective chart review.Setting: Three adult day health care centers in Brooklyn and Queens, New York.Patients: Patients with a diagnosis of type 2 diabetes and either a history of coronary artery disease or at least one other significant cardiovascular risk factor as defined by the American College of Physicians guidelines (i.e., age greater than 55 years, hypertension, left-ventricular hypertrophy, previous cerebrovascular disease, or peripheral arterial disease).Main Outcome Measures: Percentage of patients prescribed a statin for primary prevention of macrovascular complications of type 2 diabetes, percentage of patients prescribed a statin or gemfibrozil for secondary prevention of cardiovascular mortality and morbidity, and the percentage of patients on at least moderate doses of statins.Results: Ninety-three patients were evaluated—51 in the primary-prevention group and 42 in the secondary-prevention group. In the primary-prevention group, 33 (64.7%) patients were prescribed a statin, while in the secondary-prevention group, 26 (61.9%) patients were on statins, a nonsignificant difference (P = 0.8308). No patients were prescribed gemfibrozil. Of all patients prescribed statins, 63.2% were at least on moderate doses.Conclusion: This study demonstrates suboptimal treatment with statins in patients with type 2 diabetes and cardiovascular risk factors.
