Comparison of 18F-PSMA-1007 and 18F-Choline PET/CT in prostate cancer patients with biochemical recurrence: a phase 3, prospective, multicenter, randomized study.

OBJECTIVES: This prospective, multicenter, open-label, randomized, crossover trial study was to evaluate the diagnostic performance of 18F-PSMA-1007 (PSMA) vs. 18F-Choline PET/CT (FCH) in prostate cancer (PCa) patients (pts) with biochemical recurrence (BCR). METHODS: One hundred eighty-six pts, who have undergone primary definitive treatment for PCa with BCR, were recruited to this prospective study. All pts underwent one PSMA and one FCH PET/CT examination in randomized order within a time frame of 8 days and were followed up for at least 6 months (182 ±â€…10 days). RESULTS: Recurrence of PCa was observed in 176 out of 186 pts. The overall correct detection rate (DR) was 84% (95% CI 0.7967-0.8830) for PSMA and 69% (95% CI 0.6191-0.7489) for FCH, yielding a difference in proportion of 16% ( P  < 0.0001). PSMA had a sensitivity of 0.8464 and FCH 0.6857 with an odds ratio of 2.5259 ( P  < 0.0001), with statistically significant greater sensitivity of PSMA (ORs, 2.7877 and 2.1283 respectively) ( P  < 0.0001). PET/CT imaging led to a more accurate diagnosis in 166 (89.2%) pts, of which PSMA had contributed more than FCH in 91 (54.8%) of them. The DR for cutoff point PSA ≤ 1 ng/ml was higher for PSMA compared to FCH (61.8% vs. 39.5%). DR value of 51.6% for PSMA reached at PSA ≤ 0.3 ng/ml, while FCH reached that DR value with PSA ≤ 2.2 ng/ml. CONCLUSION: 18F-PSMA-1007 is more efficacious than 18F-Choline for the identification metastatic lesions both in patient and in regional level analysis in PCa patients with BCR.

Lifetime and past-year prevalence of children's exposure to violence in 9 Balkan countries: the BECAN study.

BACKGROUND: Children's exposure to violence is a major public health issue. The Balkan epidemiological study on Child Abuse and Neglect project aimed to collect internationally comparable data on violence exposures in childhood. METHODS: A three stage stratified random sample of 42,194 school-attending children (response rate: 66.7%) in three grades (aged 11, 13 and 16 years) was drawn from schools in Albania, Bosnia and Herzegovina, Bulgaria, Croatia, Former Yugoslavian Republic of Macedonia (FYROM), Greece, Romania, Serbia and Turkey. Children completed the ICAST-C questionnaire, which measures children's exposure to violence by any perpetrator. RESULTS: Exposure rates for psychological violence were between 64.6% (FYROM) and 83.2% (Greece) for lifetime and 59.62% (Serbia) and 70.0% (Greece) for past-year prevalence. Physical violence exposure varied between 50.6% (FYROM) and 76.3% (Greece) for lifetime and 42.5% (FYROM) and 51.0% (Bosnia) for past-year prevalence. Sexual violence figures were highest for lifetime prevalence in Bosnia (18.6%) and lowest in FYROM (7.6%). Lifetime contact sexual violence was highest in Bosnia (9.8%) and lowest in Romania (3.6%). Past-year sexual violence and contact sexual violence prevalence was lowest in Romania (5.0 and 2.1%) and highest in Bosnia (13.6 and 7.7% respectively). Self-reported neglect was highest for both past-year and lifetime prevalence in Bosnia (48.0 and 20.3%) and lowest in Romania (22.6 and 16.7%). Experiences of positive parental practices were reported by most participating children in all countries. CONCLUSIONS: Where significant differences in violence exposure by sex were observed, males reported higher exposure to past-year and lifetime sexual violence and females higher exposure to neglect. Children in Balkan countries experience a high burden of violence victimization and national-level programming and child protection policy making is urgently needed to address this.

USING THE PARENT-INFANT RELATIONSHIP GLOBAL ASSESSMENT SCALE TO IDENTIFY CAREGIVER-INFANT/TODDLER DYADS WITH ABUSIVE RELATIONSHIP PATTERNS IN SIX EUROPEAN COUNTRIES.

The study examined whether the Diagnostic Classification of Mental Health and Developmental Disorders of Infancy and Early Childhood, Revised Edition (DC: 0-3R; ZERO TO THREE, 2005) Parent-Infant Relationship Global Assessment Scale (PIR-GAS) is applicable to six European countries and contributes to the identification of caregiver-infant/toddler dyads with abusive relationship patterns. The sample consisted of 115 dyads with children's ages ranging from 1 to 47 months. Sixty-four dyads were recruited from community settings without known violence problems, and 51 dyads were recruited from clinical settings and already had been identified with violence problems or as being at risk for violence problems. To classify the dyads on the PIR-GAS categories, caregiver-child interactions were video-recorded and coded with observational scales appropriate for child age. To test whether the PIR-GAS allows for reliable identification of dyads with abusive relationship patterns, PIR-GAS ratings were compared with scores on the the International Society for the Prevention of Child Abuse and Neglect's (ISPCAN) Child Abuse Screening Tool-Parental Version (ICAST-P; D.K. Runyan et al., ), a questionnaire measuring abusive parental disciplinary practices. It was found that PIR-GAS ratings differentiated between the general and the clinical sample, and the dyads with abusive patterns of relationship were identified by both the PIR-GAS and the ICAST-P. Interrater reliability for the PIR-GAS ranged from moderate to excellent. The value of a broader use of tools such as the DC: 0-3R to promote early identification of families at risk for infant and toddler abuse and neglect is discussed.
