Epidemiologic evidence on the association between vitamin D and breast cancer is still inconclusive. This study analyzes the association between serum 25-hydroxyvitamin D (25(OH)D) and breast cancer risk by pathologic subtype, stage at diagnosis and specific breast cancer risk factors. We conducted a population-based multicase-control study where 546 histologically-confirmed breast cancer cases and 558 population controls, frequently matched by geographic area, age and body mass index, were recruited in 12 Spanish provinces (MCC-Spain)...

REVIEW
J Köberlein-Neu, A Seifert, I Himmelsbach
The use of self-reported vision is an integral part of most population surveys and is primarily used for healthcare monitoring. Since the patient's assessment is not always consistent with the objectively measured clinical parameters, the majority of the literature looks critically at the adequacy of self-reported vision, particularly with respect to answering epidemiological questions; however, it is often misunderstood that self-reported vision measures far more than the directly derived information show...

Bovine spastic syndrome (BSS) was described for the first time in 1941. The disease occurs in various-maybe even all-cattle breeds and is a chronic-progressive neuromuscular disorder that commonly affects cattle of at least three years of age. Typical clinical signs of the disease are clonic-tonic cramps of the hindlimbs that occur in attacks. Since BSS does not recover, affected animals can only be treated symptomatically by improving welfare conditions and management factors, or with physical therapy or drugs...

BACKGROUND: Sexual frequency is associated with the quality of life. China's internal migrants that are sexually active are more likely to participate in sexual behavior. However, less work has been undertaken to assess the sexual frequency and its predictors in migrants. AIM: This study seeks to explore which factors were related to sexual frequency in migrants and how the association varies with different levels of sexual frequency. METHODS: A total of 10,834 men and 4,928 women aged 20-49 years from 5 cities in China were enrolled by multi-stage sampling during August 2013-August 2015...

BACKGROUND: Congenital malaria is the direct infection of an infant with malaria parasites from their mother prior to or during birth. Neonatal malaria is due to an infective mosquito bite after birth. Neonatal and congenital malaria (NCM) are potentially life-threatening conditions that are believed to occur at relatively low rates in malaria endemic regions. However, recent reports suggest that the number of NCM cases is increasing, and its epidemiology remains poorly described. NCM can mimic other neonatal conditions and because it is thought to be rare, blood film examinations for malaria are not always routinely performed...

Epidemiological studies have found that maternal exposure to disinfection by-products (DBPs) may lead to adverse pregnancy outcomes although the findings tend to be inconsistent. The objective of this study was to systematically review the evidence in associated with drinking water DBP exposure in relation to adverse pregnancy outcomes. Peer-reviewed articles were identified using electronic databases searched for studies published in the English language. Studies selected for review were evaluated for exposure assessment, confounders, and analyses risks of bias in the selection, outcomes assessment, and attrition...

The use of computed tomography (CT) imaging is clearly beneficial for millions of patients. However, the potential adverse health effects, particularly cancer, of ionising radiation exposure from CT early in life are an issue of growing concern in the radiological protection, medical, and public health communities. Although efforts to quantify these effects have been conducted, the precision and accuracy of reported risks needs confirmation. EPI-CT, a European collaborative epidemiological study, was set up to quantify risks from paediatric CT to optimise paediatric diagnostic protocol...

Introduction: The debate on the current nosological status of schizophrenia and mood disorders as distinct entities is very active among scholars. There is a paucity of genetic epidemiological data to contribute an African perspective to this debate. Aim: This study aimed to assess the morbid risk of mood disorders in the relatives of schizophrenia probands, in comparison with the families of a sample of healthy controls. Subjects and Methods: This study elicited the information on the morbid risk of mood disorders among 5259 relatives of schizophrenia probands (n = 138) and 6734 relatives of healthy controls (n = 138) through direct interview of patients, available relatives of patients and the comparison group...

The incidence of multiple myeloma is characterized by a steep increase with advancing age. Dramatic improvements in survival have been reported in clinical trials; however, elderly patients are generally underrepresented in these. The aims of this study are to review patterns of incidence and survival in multiple myeloma in the general population. We searched PubMed for population-based studies on trends in incidence and survival published between January 1, 2000 and June 30, 2017 and based on regional or national cancer registries and report the following results of the review...

Despite the significance of red blood cell (RBC) alloimmunization, the lack of standardized registries in the US has prevented the completion of large studies. Data from 3·5 years of the Recipient Epidemiology and Donor Evaluation Study-III (REDS-III) recipient database, containing information from 12 hospitals, were studied. A RBC alloantibody responder had an antibody identified at any point during the study, and a non-responder had a negative antibody screen at least 15 days post-RBC transfusion. Demographics, blood type, ICD9/10 codes, and other potential correlates were evaluated...

BACKGROUND/AIMS: There is a lack of studies describing the epidemiology of colorectal cancer (CRC) in patients aged 75 years and older (elderly). Current guidelines recommend against routine screening colonoscopies in this population. We sought to describe the epidemiology of CRC in the elderly, utilizing a large, population-based database as this may impact screening guidelines in this population. METHODS: Utilizing a commercial database (Explorys Inc, Cleveland, OH), we identified a cohort of patients with a first-ever diagnosis of CRC between 2012 and 2017 based on the Systematized Nomenclature of Medicine-Clinical Terms...
