[A survey on the utilization of internet services to collect job information among medical students and initiation of video public relations activities for the recruitment of public health physicians based on the survey results].

Objectives　It is difficult for medical students to obtain information about public health physicians because there are very few public health physicians near them. To improve this situation, we surveyed the utilization of internet services to collect job information among medical students and produced six videos and conducted public relations activities for the recruitment of public health physicians based on the survey results.Methods　The subjects of the survey were medical students in their third year or above from 18 universities.

Psychological distress in men with prostate cancer and their partners before and after cancer diagnosis: a longitudinal study.

Objective: To examine the relative risk of psychological distress of men with prostate cancer and their partners during the period before and after prostate cancer diagnosis compared with men without prostate cancer and their partners.

Methods: The participants reported questionnaires on psychological distress at four time points: before prostate cancer biopsy, and at 1, 3 and 6 months following prostate cancer diagnosis. We performed multiple logistic regression analyses to examine the relative risk of psychological distress.

Psychosocial longitudinal study profile and distress of couples in relation to the conduct of prostate biopsy.

Objective: Partners of prostate cancer patients have been reported to suffer from high levels of psychological distress, although there are few reports of the changes in their distress levels observed before and after the diagnosis and the factors influencing them. This study constructed a longitudinal psychosocial database of prostate cancer biopsy subjects and their partners. This paper describes a summary of the database and the nature and severity of the psychological distress and cancer-related worry.

Radar-enabled recovery of the Sutter's Mill meteorite, a carbonaceous chondrite regolith breccia.

Doppler weather radar imaging enabled the rapid recovery of the Sutter's Mill meteorite after a rare 4-kiloton of TNT-equivalent asteroid impact over the foothills of the Sierra Nevada in northern California. The recovered meteorites survived a record high-speed entry of 28.6 kilometers per second from an orbit close to that of Jupiter-family comets (Tisserand's parameter = 2.

Proprostate-specific antigen: its usefulness in the era of multiple-core prostate biopsy.

Objective: To investigate the clinical significance of prostate-specific antigen (PSA)-related markers, including the precursor form of PSA, using the full-range area under the curve of receiver operating characteristics (AUC-ROC), partial AUC-ROC (pAUC-ROC) and multiple logistic regression analyses.

Methods: Participants consisted of 257 consecutive men (PSA range 4.1-20 ng/mL) undergoing transrectal ultrasonography-guided age-adjusted and prostate volume-adjusted multiple-core prostate biopsy at Gunma University Hospital between January 2003 and May 2005.

Changes in baseline PSA levels in Japanese men from 1988 to 2003.

Objectives: According to epidemiologic surveys, the number of deaths from prostate cancer in Japanese men increased rapidly from 1970 to 2006. However, it is difficult to know the real incidence of, and mortality due to, prostate cancer because the reliability of death certificates and the cancer registry system in Japan are poor. Recently, several studies have demonstrated that baseline prostate-specific antigen (PSA) levels could be one of the most important predictive factors for developing prostate cancer.

Nomogram ranking as new objective evaluation method in various treatment strategies for patients with prostate cancer with various clinicopathologic backgrounds.

Objectives: To propose a "nomogram ranking" that gives an objective assessment of any treatment strategy from various institutions. It is difficult to objectively compare treatment outcomes for patients with prostate cancer among institutions because of the large differences in the clinicopathologic backgrounds and treatment strategies.

Methods: From January 2001 to September 2005, 71 consecutive patients with locally advanced prostate cancer were treated with external beam radiotherapy (EBRT) and subsequent high-dose rate brachytherapy combined with long-term hormonal therapy.

Prostate-specific antigen kinetics in screen-detected prostate cancer in Japan.

Objectives: It would be of value to compare the features of prostate cancer detected in various screening series around the world. Recently, some studies have demonstrated the value of pretreatment prostate-specific antigen (PSA) kinetics in predicting the outcome of radical prostatectomy and radiotherapy for men with localized prostate cancer. Therefore, the distribution of PSA velocity (PSAV) or PSA doubling time in screen-detected prostate cancer might be objective parameters to investigate how well each national screening system is working.

Lead time of prostate cancer detected in population based screening for prostate cancer in Japan.

Purpose: We clarified that lead time bias in screen detected prostate cancer is important for evaluating the outcome of any individual screening system.

Materials And Methods: Between 1992 and 2001, 195 and 958 prostate cancer cases with clinical T1c/T2N0M0 and T3N0M0 disease were enrolled in the current study as screen detected and outpatient clinic detected prostate cancer, respectively. Log10 prostate specific antigen velocity was calculated using log10 prostate specific antigen at diagnosis and at the most recent screening before cancer detection.

Comparative study on the prevalence of clinically detectable prostate cancer in patients with and without bladder cancer.

Objectives: To investigate the prevalence of prostate cancer in patients with a past or present history of bladder cancer compared with age-matched control subjects in population-based screening for prostate cancer.

Methods: Between 1998 and 2000, 106 patients who were followed up in the outpatient clinic for bladder cancer (case cohort) and 1060 age-matched men who participated in screening for prostate cancer (control cohort) were enrolled in this study. Serum prostate-specific antigen (PSA) levels were measured for all participants, and all participants underwent digital rectal examination (DRE).

Cumulative probability of PSA increase above 4.0 NG/ML in population-based screening for prostate cancer.

Routine screening for prostate cancer remains controversial. However, it is very important to show how the optimal rescreening interval should be set for men who want to be screened after informed consent. To solve this issue, the risk of prostate-specific antigen (PSA) increase above 4.

Possibility of re-screening intervals of more than one year in men with PSA levels of 4.0 ng/ml or less.

Background: The optimal re-screening interval is one of the most important issues to evaluate the effectiveness of screening for prostate cancer.

Methods: Between 1992 and 2000, 7,026 men aged 50-78 with baseline PSA levels of 4.0 ng/ml or lower underwent screening for prostate cancer twice or more.

Natural history of PSA increase with and without prostate cancer.

Objectives: To investigate the natural history of prostate-specific antigen (PSA) increase in men with and without prostate cancer to clarify the probability of cancer-related PSA increase.

Methods: Between 1986 and 2001, 504 men aged 79 years or younger with baseline PSA levels of 4.0 ng/mL or less and a PSA increase greater than 4.
