background: this cross sectional study was carried out to determine the relationship between metal dust exposure and respiratory health in male steel workers in terengganu, malaysia. methods: subjects were interviewed using a structured questionnaire from british medical research council (bmrc) questionnaire regarding respiratory symptoms and were examined their lung function using spirometer. ...

OBJECTIVES Describe the characteristics and determine the annual cumulative incidence of traumatic brain injury (TBI) in older adults receiving home care in Ontario from 2003 to 2013. METHODS A retrospective cohort study of longitudinal data from the Ontario Association of Community Care Access Centers (N = 554,313). TBI, demographic variables, depression, neurological conditions, and recent ...

Objective: To determine incidence rates of reported work health and safety (WHS) incidents and injuries in Army Reserve (ARES) and Australian Regular Army (ARA) personnel and assess the relative performance of the WHS incident reporting system, compared to ‘point-of-care’ systems Methods: WHS incident data for a 24-month period were extracted from a military database Reported WHS incident and i...

The uniformly minimum variance unbiased (UMVU), maximum likelihood, percentile (PC), least squares (LS) and weighted least squares (WLS) estimators of the probability density function (pdf) and cumulative distribution function are derived for the generalized Rayleigh distribution. This model can be used quite effectively in modelling strength data and also modeling general lifetime data. It has...

OBJECTIVES To estimate the prevalence and cumulative incidence of gout in southern Sweden with respect to socioeconomic status. METHODS Among residents of Skåne region in the year 2013 (total population 1.3 million), adult persons (age 18 years +) who between 1998 and 2013 received a diagnosis of gout (International Classification of Disease 10th Edition (ICD-10) code M10) by any physician we...

INTRODUCTION Quantifying excess cause-specific mortality among people with coeliac disease (CD) compared with the general population accounting for competing risks will allow accurate information to be given on risk of death from specific causes. METHOD We identified from the Clinical Practice Research Datalink all patients with CD linked to Office for National Statistics between 1998 and 201...

INTRODUCTION We performed a meta-analysis to investigate the risk of deep vein thrombosis (DVT) and/or pulmonary embolisms (PEs) in patients with inflammatory arthritis, vasculitis and connective tissue diseases (CTDs) (systemic lupus erythematosus (SLE), Sjögren's syndrome, inflammatory myositis and systemic sclerosis (SSc)). METHODS PubMed, Embase, the Cochrane databases and MEDLINE were se...

Recently, in a series of papers, a method based on pseudo-values has been proposed for direct regression modeling of the survival function, the restricted mean and cumulative incidence function with right censored data. The models, once the pseudo-values have been computed, can be fit using standard generalized estimating equation software. Here we present SAS macros and R functions to compute ...

BACKGROUND An earlier investigation found increased bladder cancer incidence among workers at a rubber chemical manufacturing plant that used o-toluidine, aniline and nitrobenzene. The cohort was expanded to include additional workers (n=1875) and updated through 2007 to assess bladder cancer with improved exposure characterisation. METHODS Work histories were updated and exposure categories ...
