BACKGROUND Commercial airline crew is one of the occupational groups with the highest exposures to ionising radiation. Crew members are also exposed to other physical risk factors and subject to potential disruption of circadian rhythms. METHODS This study analyses mortality in a pooled cohort of 93 771 crew members from 10 countries. The cohort was(More)
OBJECTIVES Trends in lung cancer surgery may reveal potential for improvement and are important for planning by care providers. METHODS Using data from the Cancer Registry of Norway, we analysed the outcomes of lung cancer surgery during the periods of 1994-95, 2000-01 and 2006-07. The Cox regression model was carried out to identify the period effect on(More)
BACKGROUND The literature is inconclusive as to whether the percentage of the lepidic component of an invasive adenocarcinoma (AC) of the lung influences prognosis. We studied a population-based series of selected, resected invasive pulmonary ACs to determine if incremental increases in the lepidic component were an independent, prognostic variable. (More)
OBJECTIVE Surgical resection for lung cancer is the mainstay of curative treatment, but studies regarding postoperative results and long term outcome in the elderly have differed. The purpose of the present study was to assess the early and long-term results of surgical resection in patients more than 70 years of age. METHODS In Norway all clinical and(More)
BACKGROUND There is considerable variability in reported postoperative mortality and risk factors for mortality after surgery for lung cancer. Population-based data provide unbiased estimates and may aid in treatment selection. METHODS All patients diagnosed with lung cancer in Norway from 1993 to the end of 2005 were reported to the Cancer Registry of(More)
OBJECTIVE The postoperative mortality following lung cancer surgery is relatively high. The purpose of the present study was to identify preoperative risk factors as well as fatal complications in 27 Norwegian hospitals. METHODS In Norway, all clinical and pathologic departments submit reports on cancer patients to the Cancer Registry of Norway. The(More)
BACKGROUND Countries with a similar expenditure on healthcare within Europe exhibit differences in lung cancer survival. Survival in lung cancer was studied in 2001-2004 in England, Norway and Sweden. METHODS Nationwide cancer registries in England, Norway and Sweden were used to identify 250 828 patients with lung cancer from England, 18 386 from Norway(More)
OBJECTIVE To construct an updated comorbidity index (Patient Register Index [PRI]) using national data collections from Norway and compare its predictive ability of 1-year mortality with the Charlson Comorbidity Index (CCI). MATERIALS AND METHODS Data regarding over 1.11 million patients registered in the Norwegian Patient Register in 2010 and 2011 were(More)
OBJECTIVE Few published reports have examined the incidence and outcomes for patients with carcinoid lung tumors. The aim of the current study was to explore incidence, type of surgical treatment given, and outcome for patients with typical (TC) and atypical (AC) lung carcinoids in a national cohort (Norway). METHODS All lung-cancer patients diagnosed in(More)
In this randomized multicentre study, we compared the safety and efficacy of cefepime, 2.0 g bd i.v., with that of ceftazidime, 2.0 g tid i.v., as initial treatment of adult patients with serious infections of bacterial aetiology. Three hundred and forty-eight patients were entered into the study, 173 received cefepime and 175 ceftazidime. The treatment(More)
