[Movember health care initiative 2019: prostate cancer screening at the University Hospital Frankfurt]. / Urologische Prostatakrebsvorsorge im Rahmen der Movember-Gesundheitsinitiative 2019 am Universitätsklinikum Frankfurt.

BACKGROUND: Men die earlier than women in Germany. Men also have impaired access to cancer screening compared to women. OBJECTIVES: Our Movember campaign 2019 at University Hospital Frankfurt (UKF) aimed at improving health care awareness in the context of prostate cancer checkup. MATERIALS AND METHODS: In November 2019, every male employee of the UKF with a minimum age of 45 yrs (or 40 yrs with a first degree relative with prostate cancer) was offered a free prostate cancer checkup. This checkup contained digital rectal examination (DRE), transrectal ultrasound and PSA (prostata-specific antigen) testing. RESULTS: Overall, 121/840 employees (14.4%) participated in the Movember campaign. A first degree relative with prostate cancer was reported in overall by 14% of the participants (n = 17). At least one prior prostate cancer check up had 33%. A total of 2.5% (n = 3) had one prior negative prostate biopsy. Median age was 54 yrs (interquartile range 50-58). Median PSA level was 0.9 ng/ml and median free-PSA 0.3 ng/ml. A suspicious DRE was found in 5% (n = 6). After stratification according to age (≤ 50 yrs vs. > 50 yrs), participants over 50 yrs had a significantly higher PSA level (1.0 ng/ml vs. 0.7 ng/ml, p < 0.01) and had more frequently at least one prior prostate cancer checkup in the past (42.0 vs. 12.1%, p < 0.01). All suspicious DREs were in the cohort > 50 yrs. Overall, 32.2% (n = 39) had at least a suspicious checkup. A total of 3.3% (n = 4) had suspicious PSA levels. 17.4% (n = 21) of the participants had a suspicious PSA ratio (< 20%) only. During follow-up, 6 prostate biopsies were performed, with the detection of one case of intermediate-risk prostate cancer (Gleason 3 + 4, pT3a, pPn1, pNx, R0). CONCLUSION: Overall, 121 employees participated in our Movember Prostate cancer checkup campaign with measurement of the PSA level. Suspicious results were recorded in 32.2%. One employee was diagnosed and successfully treated with an intermediate-risk prostate cancer.

Differences in zinc status and the leptin axis in anorexic and recovered adolescents and young adults: a pilot study.

BACKGROUND: Evidence from animal studies suggests that leptin metabolism is associated with zinc (Zn) status. However, research investigating this relationship in adolescents and young adults with anorexia nervosa (AN) is scarce; the present study aims to fill that gap. METHODS: Serum concentrations of leptin, the soluble leptin receptor (sOB-R) and the free leptin index (FLI) were obtained in healthy control subjects (n=19), acutely ill individuals (n=14) and recovered patients with AN (n=15). Serum Zn concentrations noted in previous research data were also incorporated for all groups. RESULTS: Leptin, FLI and Zn concentrations were higher in recovered subjects with AN when compared with acutely ill AN patients. Remitted patients showed higher sOB-R concentrations but no difference in FLI compared with the control group. Leptin and FLI were lower in the acutely ill patients compared with the control subjects, who showed no differences in Zn concentrations. Zn concentrations were not correlated with leptin, sOB-R or FLI concentrations in any of the three investigated subgroups. CONCLUSIONS: The present investigation does not entirely support an association between Zn, Leptin and FLI concentrations in subjects with AN, possibly due to limited statistical power. Further research and replication of the present findings related to the interaction between leptin and Zn is warranted. However, with respect to serum leptin levels the data of the present investigation indicate that acutely ill and remitted patients with AN differ as regards serum leptin concentrations and FLI, which is in line with previous research.

Change in blood test after irradiation with high doses for inactivation of Lassa virus.

In 2006 we had a patient with Lassa fever in the University Hospital of Frankfurt. To insure a short turn-around time from the laboratory, it was necessary to have blood which was not contaminated with viruses. One method of achieving this is by irradiating the blood with high doses of ionising radiation. Inactivation of arena viruses requires doses between 12 kGy and 20 kGy, depending on temperature. In this study we investigated if plasma and serum parameters are changed by irradiation with 5 kGy, 10 kGy, 15 kGy, 20 kGy or 40 kGy of 10 MeV electrons. For the 22 serum parameters measured there was no influence of radiation up to 20 kGy. Only at 40 kGy was a significant decrease noted. For the six plasma parameters the values were significantly dose dependent. To correct this a mathematical function was defined. It is possible to inactivate Lassa virus with high doses of radiation. Most of the measured blood values don't change. For those which were influenced it was possible to define a mathematical function.
