An analysis was carried out of 222 medical records and autopsies from patients with inflammatory diseases of the large intestine, the immediate causes of death of whom were different disorders. The incidence of hepatitis running an active course correlated with age of patients and came up to 58.8% in the group of subjects 20 to 40 years old. In age group running between 40 to 60 and 60 to 80 years there prevailed colorectal carcinoma (18.3% and 42.5% respectively).
This study was performed to quantify adherence rates to lipid-lowering drug therapy among members of the Canadian Forces (CF) and to identify factors associated with nonadherence.
Pharmacy claims were reviewed for all CF members who received a lipid-lowering drug between April 1 and June 1, 2003. Subjects were categorized as adherent if records indicated consumption of at least 80% of prescribed doses. Logistic regression was performed to assess the impact of patient and drug characteristics upon adherence.
Overall adherence rate at 1 year was 38.5% among all users of lipid-lowering medications. Adherence did not vary among the different classes of lipid-lowering drugs. Duration of service was the only independent predictor of adherence.
Despite a relative lack of treatment barriers and the presence of established treatment programs in the CF health care system, long-term adherence with lipid-lowering medications remains suboptimal in this population.
In the present study, we evaluated whether childhood differences in body height between singletons and twins persist into adulthood. Data from the Medical Birth Register of Norway were linked with data from the Norwegian National Conscript Service. This study used data on the 457,999 males who were born alive and without physical anomalies in single or twin births in Norway during 1967-1984 and who were examined at the mandatory military conscription (age 18-20 years; 1985-2003). For sibling comparisons, the authors selected the 1,721 sibships of full brothers that included at least 1 male born in a single birth and at least 1 male born in a twin birth (4,520 persons, including 2,493 twins and 2,027 singletons). An analysis of the total study population using generalized estimating equations showed that the twins were 0.6 cm (95% confidence interval: 0.4, 0.7) shorter than were the singletons after adjustment for a series of background factors. The fixed-effects regression analysis of the sibships that included both twins and singletons showed that the twins were 0.9 cm (95% confidence interval: 0.6, 1.2) shorter than were their singleton brothers. The study suggests that male twins born in Norway during 1967-1984 were slightly shorter in early adulthood than were singletons.
In the result of the analysis of irradiation doses of 36,895 servicemen who have participated in liquidation of the Chernobyl APC disaster consequences it was found out that the average radiation dose was 12.1 cSv in 1986, 8.4 cSv in 1987, and in 1988-90 it didn't exceed 5 cSv. The irradiation received by these servicemen has depended on the time of their arrival to the zone of the disaster, the maximum permissible doses of radiation established at that period, the character of their activities and the place of their work, utilization of protection means. A conclusion was made that irradiation dose itself could be considered only as a general guide reference, because it didn't take into consideration internal irradiation and beta-irradiation of skin. That's why it is necessary to continue the further monitoring over the health status of liquidators independently of the doses of irradiation which were fixed in their histories.
BACKGROUND: A number of studies have shown variations in the occurrence of alcoholism between different socioeconomic groups and occupations, but it has not been clear to what extent this is related to the average alcohol consumption in the same socioeconomic groups or occupations. METHODS: The relationship between socioeconomic group and occupation and hospital discharge 1981-1983 due to 'diagnoses related to alcoholism' (AD) (alcohol psychosis, alcoholism, and alcohol intoxication) and liver cirrhosis was studied in a cohort of 375,035 men and 140,139 women in 13 counties in Sweden who had reported the same occupation in the censuses of 1960 and 1970. Data on alcohol consumption in different socioeconomic groups and occupations were collected from a conscription investigation and from the Swedish twin registry with data from 1969/70 and 1973 respectively. RESULTS: Intermediate or higher non-manual employees had lower risk of AD as well as of liver cirrhosis compared to manual workers for both sexes. Among males several, mostly blue-collar, occupations had increased relative risks of AD. A high level of association was found between the relative risks of AD and liver cirrhosis in socioeconomic groups, and the relative risk of AD in occupations, and the average alcohol consumption in the same socioeconomic groups/occupations among males. Such an association was not evident among women. CONCLUSION: The study shows, contrary to previous Swedish evidence, that there is a strong relationship between the incidence of alcoholism in socioeconomic groups and occupations and the average alcohol consumption in these groups among men.
In a 20-year follow-up the association between alcohol consumption, social and personal background factors and mortality was studied in a cohort of 49,464 Swedish conscripts. The relative risk of death among high consumers (those consuming more than 250 g alcohol/week at conscription) was 2.8 (95% confidence interval 2.2-3.7) compared with moderate consumers (1-100 g/week). Deaths caused by direct toxic effects of alcohol were few, less than 5%. Instead suicides and accidents predominated. Abstainers had a slightly lower mortality than moderate consumers, with a relative risk of 0.8 (0.6-1.1), due to a significantly lower risk for traffic deaths. High consumers of alcohol had more than twice as many social and personal risk factors for premature death compared with the cohort as a whole. Yet presence of social risk factors added little to the already increased relative risk of death among high consumers.
Prior studies have suggested that military service may be associated with the development of amyotrophic lateral sclerosis (ALS). We conducted a population-based case-control study in Denmark to assess whether occupation in the Danish military is associated with an increased risk of developing ALS.
There were 3,650 incident cases of ALS recorded in the Danish National Patient Registry between 1982 and 2009. Each case was matched to 100 age- and sex-matched population controls alive and free of ALS on the date of the case diagnosis. Comprehensive occupational history was obtained from the Danish Pension Fund database, which began in 1964.
2.4% (n = 8,922) of controls had a history of employment in the military before the index date. Military employees overall had an elevated rate of ALS (odds ratio [OR] = 1.3; 95% confidence interval [CI]: 1.1, 1.6). A 10-year increase in years employed by the military was associated with an OR of 1.2 (95% CI: 1.0, 1.4), and all quartiles of time employed were elevated. There was little suggestion of a pattern across calendar year of first employment, but there was some evidence that increasing age at first employment was associated with increased ALS rates. Rates were highest in the decade immediately following the end of employment (OR = 1.6; 95% CI: 1.2, 2.2).
In this large population-based case-control study, employment by the military is associated with increased rates of ALS. These findings are consistent with earlier findings that military service or employment may entail exposure to risk factors for ALS.
