BACKGROUND Breast cancer is the leading cause of female cancer in Europe and is estimated to affect more than one in 10 women. Higher socioeconomic status has been linked to higher incidence but lower case fatality, while the impact on mortality is ambiguous. METHODS We performed a systematic literature review and meta-analysis on studies on association between socioeconomic status and breast...

Today green supply chain management (GSCM) has caused increasing emphasis, as a kind of modern management mode which takes environmental impact and resource efficiency into a comprehensive consideration within the entire supply chain. A systematic literature review of green supply chain is presented in this paper, from the perspectives of concept and connotation, operations, performance evaluat...

BACKGROUND Uncertainty exists about the performance of the Framingham risk score when applied in different populations. OBJECTIVE We assessed calibration of the Framingham risk score (ie, relationship between predicted and observed coronary event rates) in US and non-US populations free of cardiovascular disease. METHODS We reviewed studies that evaluated the performance of the Framingham r...

Distinguishing cohort studies from case series is difficult.We propose a conceptualization of cohort studies in systematic reviews of comparative studies. The main aim of this conceptualization is to clarify the distinction between cohort studies and case series. We discuss the potential impact of the proposed conceptualization on the body of evidence and workload.All studies with exposure-base...

BACKGROUND Gross albuminuria is associated with increased stroke risk, but it is unclear whether stroke incidence varies by level of albuminuria. We meta-analyzed prospective cohort studies to investigate the impact of various albuminuria levels and continuous urinary albumin excretion (UAE) change on stroke risk. METHODS Systematic search for studies reporting quantitative estimates of the m...

In recent years the topic of Sustainable Supply Chain Management (sSCM) has received growing attention and has become an increasingly popular research area. Today, companies must tackle multiple new challenges: they have to address the problem of rapid climate changes, face the negative impact of the financial crisis and the prices, deal with the growing public interest in ecology (e.g. Green L...

Risk and uncertainty are ubiquitous and varied in agri-food supply chains. As environment volatility increases, only having capabilities to manage agri-food supply chain risks may not be enough, resilience factors also need to be integrated into daily operations. This paper undertakes a systematic literature review on risks sources and resilience factors in agri-food supply chains. A five-stage...

Over the last years, we have seen several security incidents that compromised system safety, of which some caused physical harm to people. Meanwhile, various risk assessment methods have been developed that integrate safety and security, and these could help to address the corresponding threats by implementing suitable risk treatment plans. However, an overarching overview of these methods, sys...

Various project management approaches do not consider the impact that uncertainties have on the project. The identified threats by uncertainty in a projec day-to-day are real and immediate and the expectations in a project are often high. The project manager faces a dilemma: decisions must be made in the present about future situations which are inherently uncertain. The use of uncertainty mana...

background: recent studies indicate an increased incidence of pertussis disease in recent years. the aim of this study was to evaluate the efficacy of the acellular vaccine for children (as a replacement of current whole cell vaccine in the expanded program on immunization) and for high-risk adults in iran through updating current best available evidence.   methods: we performed a systematic li...
