The global burden of cancer attributable to risk factors, 2010-19 : a systematic analysis for the Global Burden of Disease Study 2019

Background Understanding the magnitude of cancer burden attributable to potentially modifiable risk factors is crucial for development of effective prevention and mitigation strategies. We analysed results from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019 to inform cancer control planning efforts globally. Methods The GBD 2019 comparative risk assessment framework was used to estimate cancer burden attributable to behavioural, environmental and occupational, and metabolic risk factors. A total of 82 risk-outcome pairs were included on the basis of the World Cancer Research Fund criteria. Estimated cancer deaths and disability-adjusted life-years (DALYs) in 2019 and change in these measures between 2010 and 2019 are presented. Findings Globally, in 2019, the risk factors included in this analysis accounted for 4.45 million (95% uncertainty interval 4.01-4.94) deaths and 105 million (95.0-116) DALYs for both sexes combined, representing 44.4% (41.3-48.4) of all cancer deaths and 42.0% (39.1-45.6) of all DALYs. There were 2.88 million (2.60-3.18) risk-attributable cancer deaths in males (50.6% [47.8-54.1] of all male cancer deaths) and 1.58 million (1.36-1.84) risk-attributable cancer deaths in females (36.3% [32.5-41.3] of all female cancer deaths). The leading risk factors at the most detailed level globally for risk-attributable cancer deaths and DALYs in 2019 for both sexes combined were smoking, followed by alcohol use and high BMI. Risk-attributable cancer burden varied by world region and Socio-demographic Index (SDI), with smoking, unsafe sex, and alcohol use being the three leading risk factors for risk-attributable cancer DALYs in low SDI locations in 2019, whereas DALYs in high SDI locations mirrored the top three global risk factor rankings. From 2010 to 2019, global risk-attributable cancer deaths increased by 20.4% (12.6-28.4) and DALYs by 16.8% (8.8-25.0), with the greatest percentage increase in metabolic risks (34.7% [27.9-42.8] and 33.3% [25.8-42.0]). Interpretation The leading risk factors contributing to global cancer burden in 2019 were behavioural, whereas metabolic risk factors saw the largest increases between 2010 and 2019. Reducing exposure to these modifiable risk factors would decrease cancer mortality and DALY rates worldwide, and policies should be tailored appropriately to local cancer risk factor burden.

Arachnoid Cyst: A Solitary Intracranial Cyst in the Occipital Lobe of the Cerebrum in a Cadaver

Cyst is a closed sac, having distinct envelop; they may be filled with air, fluid, semi-solid material etc. Often cyst is a self-limiting and uneventful condition; they may get resolve with some time duration. If they fail to self-limit by themselves, depending on its size and location it needs timely surgical intervention. A cerebral cyst is a lesion with fluid filled sac in the brain. It may be benign, or malignant. This may be filled with blood, pus, Cerebrospinal Fluid (CSF), etc. Intracranial arachnoid cysts are congenital lesions of an arachnoid membrane which accounts for 1% of cases of intracranial space occupying lesions. Clinically, a brain cyst may remain silent, often it is an accidental finding on radiological investigations which are correlated in the patients with a history of vague neurological complaints. Often, headaches are a chronic complaint presented with underlying causative factors ranging from psychological stress to severe neurological deficits. The primary brain cyst that exists congenitally by birth will have no definite causality; a secondary brain cyst may exist with diversified aetiological factors including trauma. Elucidation of chronic symptoms dominated with migraine-like headache is very much essential; despite showing a good relief with a palliative treatment it will warrant clinicians to rule out cerebral cystic lesions. Such accidental findings during the dissections set as a natural cadaveric illustration, which build curiosity, and motivation among preclinical student learning from the point of integration of basic subjects. One such case of the cerebral cyst was found during the dissection in the Department of Anatomy, JSS Medical College, Mysuru, Karnataka, India. The present case is of a 70-year-old male cadaver diagnosed with the arachnoid cerebral cyst along with other varieties of cystic brain swellings

Inpatient coronary angiography and revascularisation following non-ST-elevation acute coronary syndrome in patients with renal impairment: a cohort study using the Myocardial Ischaemia National Audit Project.

BACKGROUND: International guidelines support an early invasive management strategy (including early coronary angiography and revascularisation) for non-ST-elevation acute coronary syndrome (NSTE-ACS) in patients with renal impairment. However, evidence from outside the UK suggests that this approach is underutilised. We aimed to describe practice within the NHS, and to determine whether the severity of renal dysfunction influenced the provision of angiography and modified the association between early revascularisation and survival. METHODS: We performed a cohort study, using multivariable logistic regression and propensity score analyses, of data from the Myocardial Ischaemia National Audit Project for patients presenting with NSTE-ACS to English or Welsh hospitals between 2008 and 2010. FINDINGS: Of 35 881 patients diagnosed with NSTE-ACS, eGFR of 90 ml/minute/1.73 m(2), patients with an eGFR between 45-59 ml/minute/1.73 m(2) were 33% less likely to undergo angiography (adjusted OR 0.67, 95% CI 0.55-0.81); those with an eGFR<30/minute/1.73 m(2) had a 64% reduction in odds of undergoing angiography (adjusted OR 0.36, 95%CI 0.29-0.43). Of 16 646 patients who had inpatient coronary angiography, 58.5% underwent inpatient revascularisation. After adjusting for co-variables, inpatient revascularisation was associated with approximately a 30% reduction in death within 1 year compared with those managed medically after coronary angiography (adjusted OR 0.66, 95%CI 0.57-0.77), with no evidence of modification by renal function (p(interaction) = 0.744). INTERPRETATION: Early revascularisation may offer a similar survival benefit in patients with and without renal dysfunction, yet renal impairment is an important determinant of the provision of coronary angiography following NSTE-ACS. A randomised controlled trial is needed to evaluate the efficacy of an early invasive approach in patients with severe renal dysfunction to ensure that all patients who may benefit are offered this treatment option

Colorectal cancer screening awareness and intentions among low income, sociodemographically diverse adults under age 50

Colorectal cancer (CRC) screening rates in the US are suboptimal, particularly among lower income and racial/ethnically diverse groups. If specific populations have limited awareness of screening when they reach age 50, there may be delays in screening adoption. This study investigated sociodemographic and social contextual factors associated with awareness of CRC and intentions to be screened at age 50 among 692 low income, racial, and ethnic minority adults living in low income housing. The majority of respondents (62%) were between ages 30 and 49, and 94% had some form of health insurance (e.g., Medicaid). About 70% reported having heard about CRC screening; 66% reported intentions to be screened at age 50. In multivariable analyses, screening awareness was associated with age and education. Immigrants who had English as a second language had lower awareness. Females tended to have higher awareness if they had private insurance; there were no differences among males. Multivariable analyses found that screening intentions were higher among men, those with more role responsibilities, more role conflicts, and higher levels of social cohesion. It is important to identify opportunities for maximizing screening uptake among those who become age-eligible for screening if we are to make a significant impact on CRC disparities. © 2008 Springer Science+Business Media B.V.link_to_subscribed_fulltex
