Introduction India is undergoing rapid epidemiological transition as a consequence of economic and social change. The pattern of mortality is a key indicator of the consequent health effects but ...up-to-date, precise, and reliable statistics are few, particularly in rural areas. Methods Deaths occurring in 45 villages (population 180 162) were documented during a 12-month period in 2003–04 by multipurpose primary healthcare workers trained in the use of a verbal autopsy tool. Algorithms were used to define causes of death according to a limited list derived from the international classification of disease version 10. Causes were assigned by two independent physicians with disagreements resolved by a third. Results A total of 1354 deaths were recorded with verbal autopsies completed for 98%. A specific underlying cause of death was assigned for 82% of all verbal autopsies done. The crude death rate was 7.5/1000 (95% confidence interval, 7.1–7.9). Diseases of the circulatory system were the leading causes of mortality (32%), with similar proportions of deaths attributable to ischaemic heart disease and stroke. Second was injury and external causes of mortality (13%) with one-third of these deaths attributable to deliberate self harm. Third were infectious and parasitic diseases (12%). Tuberculosis and intestinal conditions each caused one-third of deaths within this category. HIV was assigned as the cause for 2% of all deaths. The fourth and fifth leading causes of death were neoplasms (7%) and diseases of the respiratory system (5%). Conclusion Non-communicable and chronic diseases are the leading causes of death in this part of rural India. The observed pattern of death is unlikely to be unique to these villages and provides new insight into the rapid progression of epidemiological transition in rural India.
Evidence on diseases caused by or associated with alcohol use disorders (AUDs) has been based on two meta-analyses including rather dated studies. The objective of this contribution was to estimate ...the risks of all-cause mortality and alcohol-attributable disease categories depending on a diagnosis of AUDs in a national sample for France.
In a national retrospective cohort study on all inpatient acute and rehabilitation care patients in Metropolitan France 2008-2012 (N = 26,356,361), AUDs and other disease categories were identified from all discharge diagnoses according to standard definitions, and we relied on in-hospital death for mortality (57.4% of all deaths).
704,803 (2.7%) patients identified with AUDs had a threefold higher risk of death (HR = 2.98; 95% CI: 2.96-3.00) and died on average 12.2 years younger (men: 10.4, 95% CI: 10.3-10.5; women: 13.7, 95% CI: 13.6-13.9). AUDs were associated with significantly higher risks of hospital admission for all alcohol-attributable disease categories: digestive diseases, cancers (exception: breast cancer), cardiovascular diseases, dementia, infectious diseases, and injuries. Elevated risks were highest for liver diseases that were associated with about two-third of deaths in patients with AUDs (men: 64.3%; women: 71.1%).
AUDs were associated with marked premature mortality and higher risks of alcohol-attributable disease categories. Our results support the urgent need of measures to reduce the burden of AUDs.

Background
Obesity increases the risk of several types of cancer. Whether bariatric surgery influences the risk of obesity‐related cancer is not clear. This study aimed to uncover the risk of ...hormone‐related (breast, endometrial and prostate), colorectal and oesophageal cancers following obesity surgery.
Methods
This national population‐based cohort study used data from the Hospital Episode Statistics database in England collected between 1997 and 2012. Propensity matching on sex, age, co‐morbidity and duration of follow‐up was used to compare cancer risk among obese individuals undergoing bariatric surgery (gastric bypass, gastric banding or sleeve gastrectomy) and obese individuals not undergoing such surgery. Conditional logistic regression provided odds ratios (ORs) with 95 per cent confidence intervals.
Results
In the study period, from a cohort of 716 960 patients diagnosed with obesity, 8794 patients who underwent bariatric surgery were matched exactly with 8794 obese patients who did not have surgery. Compared with the no‐surgery group, patients who had bariatric surgery exhibited a decreased risk of hormone‐related cancers (OR 0·23, 95 per cent c.i. 0·18 to 0·30). This decrease was consistent for breast (OR 0·25, 0·19 to 0·33), endometrium (OR 0·21, 0·13 to 0·35) and prostate (OR 0·37, 0·17 to 0·76) cancer. Gastric bypass resulted in the largest risk reduction for hormone‐related cancers (OR 0·16, 0·11 to 0·24). Gastric bypass, but not gastric banding or sleeve gastrectomy, was associated with an increased risk of colorectal cancer (OR 2·63, 1·17 to 5·95). Longer follow‐up after bariatric surgery strengthened these diverging associations.
Conclusion
Bariatric surgery is associated with decreased risk of hormone‐related cancers, whereas gastric bypass might increase the risk of colorectal cancer.
Obesity affects cancer risk
Durvillaea incurvata is a brown macroalgae of ecological, social, and economic importance subjected to a drastic increase in harvesting pressure over the last decade in Chile. In this study, we ...performed an experimental transplantation of juveniles of D. incurvata, assessing the potential use as a restocking technique. Different types of restocking devices and attaching substrates were constructed. Differences in the D. incurvata re-attachment probability among the substrates and devices were not observed, and a high percentage of juvenile mortality was observed. However, reattached juveniles increased their length, holdfast diameter, and weight. The experiment revealed that juveniles of D. incurvata have a good capacity for reattachment and growth on artificial substrates after transplantation. This technique could be used for the species stock enhancement, although further studies are needed to optimize the process and increase the juvenile's re-attachment.
The mortality rate is high among dialysis patients, but how this compares with other diseases such as cancer is poorly understood. We compared the survival of maintenance dialysis patients with that ...for patients with common cancers to enhance the understanding of the burden of end-stage kidney disease.
Population-based cohort study.
33,500 incident maintenance dialysis patients in Ontario, Canada, and 532,452 incident patients with cancer (women: breast, colorectal, lung, or pancreas; men: prostate, colorectal, lung, or pancreas) from 1997 to 2015 using administrative health care databases.
Incident kidney failure treated with maintenance dialysis versus incident diagnoses of cancer.
All-cause mortality.
Kaplan-Meier product limit estimator was used to describe the survival of subgroups of study participants. Extended Cox regression with a Heaviside function was used to compare survival between patients with incident kidney failure treated with maintenance dialysis and individual diagnoses of various incident cancers.
In men, dialysis had worse unadjusted 5-year survival (50.8%; 95% CI, 50.1%-51.6%) compared with prostate (83.3%; 95% CI, 83.1%-83.5%) and colorectal (56.1%; 95% CI, 55.7%-56.5%) cancer, but better survival than lung (14.0%; 95% CI, 13.7%-14.3%) and pancreas (9.1%; 95% CI, 8.5%-9.7%) cancer. In women, dialysis had worse unadjusted 5-year survival (49.8%; 95% CI, 48.9%-50.7%) compared with breast (82.1%; 95% CI, 81.9%-82.4%) and colorectal (56.8%; 95% CI, 56.3%-57.2%) cancer, but better survival than lung (19.7%; 95% CI, 19.4%-20.1%) and pancreas (9.4%; 95% CI, 8.9%-10.0%) cancer. After adjusting for clinical characteristics, similar results were found except when examining men and women with lung and pancreas cancer, for which dialysis patients had a higher rate of death 4 or more years after diagnosis. Women and men 70 years and older with incident kidney failure treated with maintenance dialysis had unadjusted 10-year survival probabilities that were comparable to pancreas and lung cancer.
Cancer stage could be obtained for only a subpopulation.
Survival in incident dialysis patients was lower than in patients with several different solid-organ cancers. These results highlight the need to develop interventions to improve survival on dialysis therapy and can be used to aid advance care planning for elderly patients beginning treatment with maintenance dialysis.
Aims/hypothesis
The aim of the study was to describe trends in all-cause and cause-specific mortality rates in Hong Kong Chinese people with diabetes from 2001 to 2016.
Methods
The Hong Kong Diabetes ...Surveillance Database (HKDSD) is a territory-wide diabetes cohort identified from the Hong Kong Hospital Authority electronic medical record system. Deaths between 2001 and 2016 were identified from linkage to the Hong Kong Death Registry. We used Joinpoint regression analysis to describe mortality patterns among people with diabetes by age and sex, and standardised mortality ratios (SMRs) to compare all-cause mortality rates in people with and without diabetes.
Results
Between 2001 and 2016, a total of 390,071 men and 380,007 women aged 20 years or older with diabetes were included in the HKDSD. There were 96,645 deaths among men and 88,437 deaths among women. Mortality rates for all-cause, cardiovascular disease and cancer among people with diabetes declined by 52.3%, 72.2% and 65.1% in men, respectively, and by 53.5%, 78.5% and 59.6% in women, respectively. Pneumonia mortality rates remained stable. The leading cause of death in people with diabetes has shifted from cardiovascular disease to pneumonia in the oldest age group, with cancer remaining the most common cause of death in people aged 45–74 years. The all-cause SMRs for men declined from 2.82 (95% CI 2.72, 2.94) to 1.50 (95% CI 1.46, 1.54), and for women, they declined from 3.28 (95% CI 3.15, 3.41) to 1.67 (95% CI 1.62, 1.72). However, among people aged 20–44 years, the declines in all-cause mortality rates over the study period were not statistically significant for both men (average annual per cent change AAPC: −3.2% 95% CI −7.3%, 1.0%) and women (AAPC: −1.2% 95% CI −6.5%, 4.4%). The SMRs in people aged 20−44 years fluctuated over time, between 7.86 (95% CI 5.74, 10.5) in men and 6.10 (95% CI 3.68, 9.45) in women in 2001, and 4.95 (95% CI 3.72, 6.45) in men and 4.92 (95% CI 3.25, 7.12) in women in 2016.
Conclusions/interpretation
Absolute and relative mortality has declined overall in people with diabetes in Hong Kong, with less marked improvements in people under 45 years of age, calling for urgent action to improve care in young people with diabetes.
