This brief review has highlighted some of the research done by the MRC in the South Wales valleys. The two MRC Units published, in total, over 2000 reports ranging from letters to journals to conference proceedings, with around 200 reports appearing in the BMJ, Lancet and Nature alone. The expertise gained in South Wales meant that the Pneumoconiosis Research Unit team was involved internationally in co-ordinating research on coal workers' lung disease, and later on the health effects of asbestos and other respirable dusts. It is remarkable that the early large-scale studies were conducted and analysed without the benefits of modern computers and statistical packages. The varied Epidemiology Unit research programme enabled Cochrane to develop his ideas on defining health and evaluating health services, and also Elwood, who directed the Unit from 1974 to 1995, to pioneer studies of aspirin prophylaxis in cardiovascular disease. A steady stream of occupational health studies were carried out by Epidemiology Unit staff and many other large surveys were conducted in other parts of South Wales and across the country. Later MRC Epidemiology Unit work has focused on the town of Caerphilly where a prospective study of some 2500 men, established in 1979, has so far resulted in over 100 papers, notably on haemostatic factors related to heart disease. The study has run in tandem with a similar survey in the Speedwell area of Bristol which was established by former Epidemiology Unit staff working for the health authority in that area. Other medical research groups have also worked in the South Wales valleys. In 1961 Julian Tudor Hart left the Epidemiology Unit after a year's research to enter general practice, and establish the famous research practice at Glyncorrwg, over the mountain from the Rhondda Fawr. This year the extensive collection of MRC survey records is being transferred to the Department of Social Medicine at Bristol, and it is quite likely that further research will be undertaken relating Rhondda survey data collected over 40 years ago to subsequent mortality. The South Wales valleys will continue to contribute to medical research into the next millennium. Archie Cochrane's papers have been catalogued and are available for study at the Cochrane Archive established at Llandough Hospital.

Major death cause among occupational diseases patients is cardiovascular disorder. Early diagnosis is required to predict heart disorders in occupational risk group. Rhythmocardiography helped to define autonomous cardioneuropathy on background of vibration disease, pneumoconiosis, chronic occupational fluorine-manganese intoxication--this is a pathogenetic basis for early clinical manifestation of CHD.

Invasive pneumococcal disease (IPD) is a main cause of mortality associated with pneumococcal infections. Although, IPD is regarding mainly small children and persons in the age > 65 years, the investigations showed that because of IPD exactly sick persons are burdened with the greatest mortality in the older age, rather than of children. The most frequent form of IPD is community acquired pneumonia (CAP) with the bacteremia. The presence of even a single additional risk factor is increasing the probability of the unfavorable descent of pneumococcal infection. The risk factors for IPD and/or pneumonia with bacteremia apart from the age are among others asthma (> 2 x), chronic obstructive pulmonary disease (COPD), sarcoidosis (4 x), idiopathic pulmonary fibrosis (5 x), bronchiectases (2 x), allergic alveolitis (1.9 x) and pneumoconiosis (2 x), type 1 diabetes (4.4 x), type 2 diabetes (1.2 x), autoimmune diseases (e.g. rheumatoid arthritis (4.2 to 14.9 x), kidney failure with the necessity to dialysis (12 x), immunosuppression, cardiovascular disease, alcoholism and cancers. Examinations show that the best method of IPD and CAP preventing are pneumococcal vaccinations. On the market for ages 23-valent polysaccharide vaccine (PPV23) is available covering close the 90% of IPD triggering stereotypes. Her role in preventing CAP is uncertain and the immunological answer after vaccination at older persons and after revaccination is weak. Widely discussed disadvantageous effects of growing old of the immunological system show on the benefit from applying the immunization inducing the immunological memory, i.e. of conjugated vaccines which are activating the T-dependent reply and are ensuring the readiness for the effective secondary response. Examinations so far conducted with conjugated 7-valent and 13-valent (PCV13) vaccines at persons in the age > 50 years are confirming these expectations. Also sick persons can take benefits from PCV13 applying back from so-called IPD risk groups in the age > 19 years. At these work research findings were described above PPV23 and PCV13 at adults and world recommendations of applying both vaccines in risk groups from 19 years up to the advanced years. Also Polish recommendations of optimum applying of these vaccines were presented. They are recommending applying PCV13 at first in them, while PPV23, if to her readings exist should be given to > or = 8 of weeks from PCV13. In persons > or = 19 years which earlier received 1 or should receive more PPV23 doses first PCV13 dose should be given after the year or later than the last PPV23 dose, and then again PPV23 > or = 8 of weeks from PCV13 and the second PPV23 dose not earlier than 5 years from last PPV23. If the PPV23 application seems to be justified, it is irrespective of the more previous state vaccination against pneumococci, PCV13 should be given to as first.

Although past studies have confirmed that chronic dust exposure is a risk factor for cardiovascular disease, the relationship between it and cerebrovascular disease is still unclear. We aimed to determine whether pneumoconiosis is related to increased incidence of ischemic stroke in the following 5 to 11 years. We selected 1238 patients with pneumoconiosis from Taiwan's National Health Insurance database as our study cohort. After matching for age, sex and the date of ambulatory care visit, another 4952 patients without pneumoconiosis were selected as the comparison cohort. Each patient was individually followed up until the end of 2010 to track the incidence of stroke, and Cox proportional hazard regression analysis was performed to compute the relative hazard ratio of stroke. Our results showed 19.6% of pneumoconiosis patients and 15.8% of non-pneumoconiosis patients developed stroke. After statistically adjusting for age, sex, and medical comorbidities, the hazard of developing stroke was 1.36 times greater for those with pneumoconiosis compared to those without. Even in those with pneumoconiosis excluding chronic obstructive pulmonary disease, the hazard of developing stroke was still 1.31 times greater than those without pneumoconiosis. Our study revealed that pneumoconiosis patients are at a higher risk of ischemic stroke, and primary prevention of stroke is particularly important in this group of patients.

Interstitial lung disease (ILD) is a chronic, progressive fibrotic lung disease with a dismal prognosis. ILD of unknown etiology is referred to as idiopathic interstitial pneumonia (IIP), which is sporadic in the majority of cases. ILD is frequently accompanied by rheumatoid arthritis (RA), systemic sclerosis (SSc), polymyositis/dermatomyositis (PM/DM), and other autoimmune diseases, and is referred to as collagen vascular disease-associated ILD (CVD-ILD). Susceptibility to ILD is influenced by genetic and environmental factors. Recent advances in radiographic imaging techniques such as high-resolution computed tomography (CT) scanning as well as high-throughput genomic analyses have provided insights into the genetics of ILD. These studies have repeatedly revealed an association between IIP (sporadic and familial) and a single nucleotide polymorphism (SNP) in the promoter region of the mucin 5B (MUC5B). HLA-DRB1*11 alleles have been reported to correlate with ILD in European patients with SSc, whereas in Japanese patients with RA, the HLA-DR2 serological group was identified. The aim of this review is to describe the genetic background of sporadic IIP, CVD-ILD, drug-induced-ILD (DI-ILD), pneumoconiosis, and hypersensitivity pneumonitis. The genetics of ILD is still in progress. However, this information will enhance the understanding of the pathogenesis of ILD and aid the identification of novel therapeutic targets for personalized medicine in future.
