Work in progress: radioprotection of human breast cancer cells by elevation of intracellular cyclic AMP

MCF-7 human breast cancer cells that were treated for one hour prior to X irradiation with the cyclic AMP-inducing agent 1-methyl-3-isobutylxanthine displayed a slight but significant increase in surviving fraction over untreated controls at each radiation dose level. This was accompanied by a two-fold increase in the level of intracellular cyclic AMP.     

Early postoperative changes in graft thickness after penetrating keratoplasty. Influence of host corneal disorder on time course.

In 172 patients the thickness of the corneal graft was followed with frequent measurements during the first 14 days after operation. Three different graft thickness time courses were observed. Patients with keratitis, stromal dystrophy and corrosion or mechanical lesion showed a secondary rise in graft thickness on the 6th postoperative day, while patients with keratoconus and those treated with tranexamic acid showed no rise on the 6th day. Patients with Fuchs' dystrophy differed from the other groups in not reaching the maximal thickness until the 3rd postoperative day. The possible correlation of these three time courses with changes in the fibrinolytic system is discussed.     

Mental and physical health problems of, and the use of healthcare by, Afghan, Iranian and Somali asylum seekers and refugees

OBJECTIVE: To estimate the prevalence rates of mental and physical health problems and the use of healthcare services among adult asylum seekers and recognised refugees from Afghanistan, Iran and Somalia in the Netherlands. DESIGN: Cross-sectional study. METHOD: Asylum seekers were approached in 14 reception centres and refugees were interviewed in 3 municipalities (Arnhem, Leiden and Zaanstad). Respondents were interviewed in their own language and asked questions pertaining to: general health, chronic complaints, symptoms of post-traumatic stress disorder (PTSD), symptoms of depression/ anxiety, the use of healthcare services (general practitioner, medical specialists, hospitalisation, mental-health services, medication) and background variables. RESULTS: A total of 232 asylum seekers and 178 refugees participated (response rates of89% and 59%, respectively). Of these, 142 (61%) and 99 (56%), respectively were males and the average age was 34.4 (SD: 11.o) and 40.3 (SD: 13.3) years, respectively. Compared to refugees, asylum seekers more often considered their health to be poor (42% and 59%, respectively), had more symptoms of depression/anxiety (39% and 68%, respectively), and had more symptoms of PTSD (11% and 28%, respectively). No differences were found between refugees and asylum seekers in the self-reported use of healthcare services. CONCLUSION: This study showed that asylum seekers have more health problems than refugees, but that there are no differences in the self-reported use of healthcare services. More research is needed to answer the question ifasylum seekers have sufficient access to the healthcare system.
