BACKGROUND & AIMS The molecular features of colorectal tumors differ with their anatomic location. Colorectal tumors are usually classified as proximal or distal. We collected data from 3 cohorts to identify demographic, clinical, anthropometric, lifestyle, and dietary risk factors for colorectal cancer (CRC) at 7 anatomic subsites. We examined whether the associations differ among refined subsites and whether there are trends in associations from cecum to rectum. METHODS We collected data from the Nurses' Health Study, Nurses' Health Study 2, and Health Professionals Follow-up Study (45,351 men and 178,016 women, followed for a median 23 years) on 24 risk factors in relation to risk of cancer in cecum, ascending colon, transverse colon, descending colon, sigmoid colon, rectosigmoid junction, and rectum. Hazard ratios were estimated using Cox proportional hazards regression. We tested for linear and non-linear trends in associations with CRC among subsites and within proximal colon, distal colon, and rectum. learn more isk factor profiles differed for cancers along the colorectum. Proximal vs distal classifications are not sufficient to encompass the regional variations in colorectal tumor features and risk factors. BACKGROUND To investigate to what extent early Lyme borreliosis patients with erythema migrans are infected with Anaplasma phagocytophilum. METHODS Three hundred ten patients from Poland with erythema migrans were included in the study. One hundred and eighty-three patients (59%) agreed to have both skin biopsy and blood samples analysed for Borrelia burgdorferi, A. phagocytophilum and 'Candidatus Neoehrlichia mikurensis', with PCR. Positive samples were confirmed with sequencing. RESULTS B. burgdorferi DNA was detected in 49.7% of the skin samples and in 1.1% of the blood samples. A. phagocytophilum DNA was found in 7.1% blood samples, and in 8.2% of the skin biopsies. In four patients, A. phagocytophilum DNA was detected only in blood; in one case A. phagocytophilum DNA was found simultaneously in blood and skin, and additionally in this patients' blood Borrelia DNA was detected. In four skin samples B. burgdorferi DNA was detected simultaneously with A. phagocytophilum DNA, indicative of a co-infection. CONCLUSIONS A. phagocytophilum may be present in early Lyme borreliosis characterized by erythema migrans and should always be considered as a differential diagnostic following a tick bite and considered in treatment schemes, as these differs (in early stage of Lyme borreliosis doxycycline, amoxicillin, cefuroxime axetil and azithromycin are recommended, while in anaplasmosis the most effective courses of treatment are doxycycline, rifampin and levofloxacin). Consequently, the role of A. phagocytophilum in erythema migrans should be further studied. Covid-19 is a global pandemic that is wreaking havoc with the health and economy of much of human civilization. Electrophysiologists have been impacted personally and professionally by this global catastrophe. In this joint document from representatives of the HRS, ACC and AHA we identify the potential risks of exposure to patients, allied health care staff, industry representatives and hospital administrators. We describe the impact of COVID-19 on cardiac arrhythmias and methods of triage based on acuity and patient comorbidities. We provide guidance for managing invasive and non-invasive electrophysiology procedures, clinic visits and cardiac device interrogations. We discuss resource conservation and the role of tele-medicine in remote patient care along with management strategies for affected patients. There is suggestive evidence for the role of vitamin D in the development of colorectal cancer (CRC). Due to high latitudes in Canada, many Canadians are vitamin D deficient throughout winter. In this analysis, we examined the association between vitamin D supplement use and high-risk adenomatous polyps (HRAPs). The study population was drawn from the biorepository at the Forzani & MacPhail Colon Cancer Screening Centre (CCSC) in Calgary. Individuals enrolled between 2013 and 2016 between the age of 50 and 74 years (n = 1409) were included. When examining the association between any supplemental vitamin D use and HRAPs, a protective effect is observed with an ORadj of 0.57 (95% CI 0.33-0.96). Similarly, meeting the recommended daily intake (RDI) of vitamin D (600 IU) is protective against HRAPs with an ORadj of 0.78 (95% CI 0.62-0.99). This study suggests that adequate vitamin D supplementation reduces the occurrence of colorectal polyps in high-latitude locations. Although the relationship between cigarette smoking and increased risk of malignancy has been well established, smoking remains a major public health threat in the United States. Therefore, we examined the relationship between a person's level of trust in cancer information from their physician and the likelihood of quitting smoking in order to better understand the doctor-patient relationship in the context of smoking cessation. The Health Information Nation Trends Survey (2011-2015) was used to identify smokers (n = 2186). Multivariable logistic regression was used to assess the relationship between trust in physicians, the internet, and family members on smoking cessation, accounting for demographic variables. Smokers reported a significantly higher level of trust in cancer information from their physician than cancer information from the internet or family members. However, no significant association between level of trust in cancer information from their physician and wanting to quit smoking was observed (ptrend = 0.55). There was also no association between level of trust in the internet or family and quitting smoking (ptrend = 0.52 and ptrend = 0.83, respectively). These results were confirmed by multivariate analysis. Smoking cessation is not associated with the level of trust an individual has in cancer information from their physician, the internet, or from family members. These findings may impact the utility of standardized information campaigns. The Scale-Up project introduced vaginal self-sampling and low-cost human papillomavirus (HPV) testing as the primary approach for cervical cancer screening in selected public health centers in Guatemala, Honduras, and Nicaragua. We evaluate the country-specific accomplishments in screening target-coverage, triage, and treatment. Between 2015 and 2018, cervical cancer screening was offered to women at least 30 years of age. Triage of HPV-positive women was based on visual inspection with acetic acid or Pap. Aggregated data included total women screened, use of self-sampling, age, time elapsed since last screening, HPV results, triage tests, triage results, and treatment. A total of 231,741 women were screened for HPV, representing 85.8% of the target populations within the project. HPV positivity was lower in Guatemala (12.4%) compared to Honduras and Nicaragua (14.5% and 14.2%, respectively, p  less then  0.05). A follow-up triage test was completed for 84.2%, 85.8%, and 50.1% of HPV-positive women in Guatemala, Nicaragua, and Honduras, respectively.
