A nurse- and peer-led psycho-educational intervention to support women with gynaecological cancers receiving curative radiotherapy: The PeNTAGOn randomised controlled trial - ANZGOG 1102.

OBJECTIVE: Radiotherapy for gynaecological cancer is associated with multiple adverse effects. This randomised controlled trial evaluated the impact of a combined nurse- and peer-led psycho-educational intervention on psychological distress, preparation for treatment, quality of life, psychosexual function, unmet needs and vaginal stenosis. METHODS: Eligible women had a confirmed diagnosis of gynaecological cancer, scheduled to receive radiotherapy with curative intent, aged ≥18 years, and able to read and write English. Participants randomly assigned one-to-one to either four nurse-led consultations plus four peer-led telephone sessions, or to usual care. Participants completed study measures at baseline, immediately before first radiotherapy (FU1), and four weeks (FU2), three (FU3), six (FU4), and 12 months (FU5) post radiotherapy. The primary outcomes were psychological distress at FU1 and FU2 measured by the Hospital Anxiety and Depression Scale. RESULTS: Of 840 eligible participants, 625 were approached and 319 (51%) consented; 158 assigned to intervention, 160 to usual care with 1 withdrawing before randomisation. Between-groups differences for primary outcomes were trivial- and small-sized, (both p > 0.05). Notable effects on secondary outcomes favouring the intervention at FU2 included preparation for treatment (sensory/psychological concerns, d = 0.57; and procedural concerns, d = 0.52) and specific needs domains (sexuality needs, d = 0.38; and health system and information needs, d = 0.41). CONCLUSIONS: There was no evidence that a nurse- and peer-led intervention had a beneficial effect on psychological distress compared to usual care. However, improved treatment readiness and lower health system and sexuality needs indicate the intervention may have addressed outcomes known to be important to this population.

The modified Memorial Symptom Assessment Scale Short Form: a modified response format and rational scoring rules.

PURPOSE: The Memorial Symptom Assessment Scale Short Form (MSAS-SF) is a widely used symptom assessment instrument. Patients who self-complete the MSAS-SF have difficulty following the two-part response format, resulting in incorrectly completed responses. We describe modifications to the response format to improve useability, and rational scoring rules for incorrectly completed items. METHODS: The modified MSAS-SF was completed by 311 women in our Peer and Nurse support Trial to Assist women in Gynaecological Oncology; the PeNTAGOn study. Descriptive statistics were used to summarise completion of the modified MSAS-SF, and provide symptom statistics before and after applying the rational scoring rules. Spearman's correlations with the Functional Assessment for Cancer Therapy-General (FACT-G) and Hospital Anxiety and Depression Scale (HADS) were assessed. RESULTS: Correct completion of the modified MSAS-SF items ranged from 91.5 to 98.7%. The rational scoring rules increased the percentage of useable responses on average 4% across all symptoms. MSAS-SF item statistics were similar with and without the scoring rules. The pattern of correlations with FACT-G and HADS was compatible with prior research. CONCLUSION: The modified MSAS-SF was useable for self-completion and responses demonstrated validity. The rational scoring rules can minimise loss of data from incorrectly completed responses. Further investigation is recommended.

In vitro pregnenolone metabolism by mouse adrenal gland: I-estrogen synthesis.

Adrenal gland homogenates from four different strains of mice were incubated with (4-14C)-pregnenolone and a NADPH generating system. Although quantitative differences between high and low mammary tumor strains occured, all mice synthesized estrone. The highest aromatase activity was found 2 months after castration of the (C3H x RIII) F1 mice when castration was performed at 4 days of age; this activity was lower in the C3H mice and almost negligible in the RIII and C57BL mice.
