Mobile phones emit electromagnetic radiations that are classified as possibly carcinogenic to humans. Evidence for increased risk for brain tumours accumulated in parallel by epidemiologic investigations remains controversial. This paper aims to investigate whether methodological quality of studies and source of funding can explain the variation in results. PubMed and Cochrane CENTRAL searches were conducted from 1966 to December 2016, which was supplemented with relevant articles identified in the references...

S M Zaki, D W Denning
We aimed to estimate the burden of serious fungal infections in Egypt, currently unknown, based on the size of the populations at risk and available epidemiological data. Data were obtained from the World Health Organization (WHO), the Joint United Nations Programme on HIV/AIDS (UNAIDS), and published reports with clearcut denominators. When no data existed, risk populations were used to estimate frequencies of fungal infections, using previously described methodology. The population of Egypt in 2011 was ∼82,500,000; 31% children, and 8% women >60 years of age...

OBJECTIVE: The use of antibiotic prophylaxis (AP) for prevention of infective endocarditis (IE) is controversial. In recent years, guidelines to cardiologists and dentists have advised restriction of AP to high-risk groups (in Europe and the USA) or against its use at all (in the UK). The objective of this systematic review was to appraise the evidence for use of AP for prevention of bacteraemia or IE in patients undergoing dental procedures. METHODS: We conducted electronic searches in Medline, Embase, Cochrane Library and ISI Web of Science...

REVIEW
Augustin Toma, Guillaume Paré, Darryl P Leong
PURPOSE OF REVIEW: Previous research suggests that low-moderate alcohol consumption may have cardioprotective effects, while heavy or binge-pattern drinking is harmful. New evidence and research methodology may inform safe thresholds of alcohol use. This review examines recent evidence regarding alcohol's effect on cardiovascular disease, with a special consideration of pattern, drink type, and total quantity. RECENT FINDINGS: New epidemiologic research confirms the potential harmful cardiovascular effects of heavy episodic alcohol use and does not support the previous observation that low-moderate alcohol use protects against stroke...

Background: Air pollution has been demonstrated to be a major risk factor for the development of cardiovascular and respiratory diseases worldwide. This study examines the relationship between the exposure to fine particulate matter (PM) and patient hospitalizations as a result of ischemic heart disease (IHD) during 2013-2014 in Shanghai, China. Methods: Daily IHD hospitalization data were acquired from the Shanghai Health Insurance Bureau (SHIB) from 1 January 2013 to 21 December 2014. Daily average concentrations of air pollution as well as meteorological data were obtained from the database of Shanghai Environmental Monitoring Center (SEMC) during the same time period, and all data were analyzed using standard epidemiological methodology...

BACKGROUND: It is important that all undergraduate healthcare students are equipped with evidence-based health care (EBHC) knowledge and skills to encourage evidence-informed decision-making after graduation. We assessed EBHC teaching and learning in undergraduate human nutrition (HN); occupational therapy (OT); physiotherapy (PT); and speech, language and hearing therapy (SPLH) programs at a sub-Saharan African university. METHODS: We used methodological triangulation to obtain a comprehensive understanding of EBHC teaching and learning: (1) through a document review of module guides, we identified learning outcomes related to pre-specified EBHC competencies; we conducted (2) focus group discussions and interviews of lecturers to obtain their perspectives on EBHC and on EBHC teaching and learning; and we (3) invited final year students (2013) and 2012 graduates to complete an online survey on EBHC attitudes, self-perceived EBHC competence, and their experience of EBHC teaching and learning...

Breakpoints are used to predict whether an antifungal agent will be clinically effective against a particular fungal isolate. They are based on a combination of MIC values, pharmacokinetic/pharmacodynamic values and clinical outcome data. For many fungus/antifungal combinations this data will never be available. For these combinations Epidemiological Cutoff Values (ECVs) provide a methodology to categorize isolates as either wild type or non-wild type. This review defines ECVs, explains how they are generated using the CLSI methodology in standard M57, and describes how they can be used in clinical practice...

Nodding syndrome is an epileptic disorder of unknown etiology that occurs in children in East Africa. There is an epidemiological association with Onchocerca volvulus, the parasitic worm that causes onchocerciasis (river blindness), but there is limited evidence that the parasite itself is neuroinvasive. We hypothesized that nodding syndrome may be an autoimmune-mediated disease. Using protein chip methodology, we detected autoantibodies to leiomodin-1 more abundantly in patients with nodding syndrome compared to unaffected controls from the same village...

BACKGROUND: During the last decades, sex and gender biases have been identified in various areas of biomedical and public health research, leading to compromised validity of research findings. As a response, methodological requirements were developed but these are rarely translated into research practice. The aim of this study is to provide good practice examples of sex/gender sensitive health research. METHODS: We conducted a systematic search of research articles published in JECH between 2006 and 2014...

Emerging epidemiological evidence suggests that patients with glucose-6-phosphate dehydrogenase (G6PD) deficiency may have a higher risk of developing diabetes. The aim of the review was to synthesise the evidence on the association between G6PD deficiency and diabetes. A systematic search on Medline, EMBASE, AMED and CENTRAL databases for studies published between January 1966 and September 2016 that assessed the association between G6PD deficiency and diabetes was conducted. This was supplemented by a review of the reference list of retrieved articles...

BACKGROUND: Cancer incidence rates and trends for cases diagnosed through 2014 using data reported to the Surveillance, Epidemiology, and End Results (SEER) program in February 2016 and a validation of rates and trends for cases diagnosed through 2013 and submitted in February 2015 using the November 2015 submission are reported. New cancer sites include the pancreas, kidney and renal pelvis, corpus and uterus, and childhood cancer sites for ages birth to 19 years inclusive. METHODS: A new reporting delay model is presented for these estimates for more consistent results with the model used for the usual November SEER submissions, adjusting for the large case undercount in the February submission...

REVIEW
Justin Parker, Rolf Scharfbillig, Sara Jones
BACKGROUND: Xerosis, literally dryness of the skin, of the foot is a common condition encountered clinically, which can lead to discomfort and predisposition to infection. Currently, there are no evidence-based recommendations on which moisturiser formulations best alleviate xerotic symptoms. The aim of this review was to guide clinical practice in the treatment of primary and diabetes related foot xerosis, by identifying from the existing literature the most effective ingredient or formulation of topical treatments for symptoms of primary foot xerosis in the general population...

Research and policies on child and adolescent sexual exploitation frequently focus on the sexual exploitation of girls and fail to recognize the experiences of sexually exploited boys, including their potentially unique health care and social support needs. This oversight limits the ability of health care and social service providers to offer both targeted and evidence informed care to sexually exploited boys. As a first step in a larger grant to understand the experiences of sexually exploited boys and to develop interventions for this specific population, we conducted a systematic review to address the question, "What is the state of the research on sexually exploited boys internationally?" As we undertook this review, we faced a number of significant challenges that made the process more difficult than anticipated...

BACKGROUND: The pork tapeworm, Taenia solium, and associated human infections, taeniasis, cysticercosis and neurocysticercosis, are serious public health problems, especially in developing countries. The World Health Organization (WHO) has set goals for having a validated strategy for control and elimination of T. solium taeniasis/cysticercosis by 2015 and interventions scaled-up in selected countries by 2020. Timely achievement of these internationally-endorsed targets requires that the relative benefits and effectiveness of potential interventions be explored rigorously within a quantitative framework...

BACKGROUND: Western countries are increasingly using complementary and alternative medicine (CAM) to assist with relieving ailments. Turmeric, from the ginger family Zingiberaceae, has a history of use for medicinal purposes. The polyphenols found in turmeric (curcuminoids) have demonstrated anti-inflammatory and pain relieving properties. With the use of CAMs increasing, it is important for the effectiveness of curcuminoids to be established. OBJECTIVES: To identify the effectiveness of the use of curcuminoids for the amelioration of musculoskeletal pain...

BACKGROUND: Hospital readmission in older persons is common and reported as a post-discharge adverse outcome from hospitalization. Readmission relates to a mix of factors associated with increasing age, living conditions, progression of disease as well as factors related to the processes of care. To allow health professionals to focus more intensively on patients at risk of readmission, there is a need to identify the characteristics of those patients. OBJECTIVES: To identify and synthesize the best available evidence on risk factors for acute care hospital readmission within one month of discharge in older persons in Western countries...

Left-truncated data often arise in epidemiology and individual follow-up studies due to a biased sampling plan since subjects with shorter survival times tend to be excluded from the sample. Moreover, the survival time of recruited subjects are often subject to right censoring. In this article, a general class of semiparametric transformation models that include proportional hazards model and proportional odds model as special cases is studied for the analysis of left-truncated and right-censored data. We propose a conditional likelihood approach and develop the conditional maximum likelihood estimators (cMLE) for the regression parameters and cumulative hazard function of these models...
