A randomized controlled trial on the effectiveness of the abridged illness management and recovery program for people with schizophrenia spectrum disorders.

Objective: This study aimed to investigate the effectiveness of an abridged version of the Illness Management and Recovery Programme (AIMR) that was modified and developed in Hong Kong through a mult-centre randomized controlled trial for patients with schizophrenia spectrum disorders. Methods: This study was implemented in 10 occupational therapy departments, psychiatric day hospitals of 7 Hospital Authority clusters in Hong Kong. A total of 211 patients with schizophrenia or schizoaffective disorder was recruited and randomized into either the experimental or the control condition. In the control group, the subjects went through conventional occupational therapy programmes. In the experimental group, the subjects went through an additional 10-session programme of AIMR. Participants: were measured at baseline, completion of the AIMR, and 3-month after the AIMR programme. Measures include the expanded version of the Brief Psychiatric Rating Scale (BPRS-E), the client version of the Illness Management and Recovery Scale (IMRS), the Snyder Hope Scale, the Social and Occupational and Occupational Functioning Assessment Scale (SOFAS), the WHO Quality of Life Scale (WHOQOL-BREF), and the Chinese Version of the Short Warwick-Edinburgh Mental Well-Being Scale (C-SWEMWBS). Results: Both the experimental and control cohorts had comparable clinical and socio-demographic characteristics except years of education and duration of illness. These two variables were entered as covariates in the linear mixed model which showed that the experimental group had significantly higher improvement than the control group in terms of illness management (F = 4.82; p = .03; Cohen's d = .45), functional (F = 10.65; p = .001; Cohen's d = .58), and hope (F = 5.52; p = .02; Cohen's d = .08) measures after the completion of treatment. Conclusion: The results supported the effectiveness of the AIMR programm which would be important in the recovery oriented practices in psychiatry.

Patterns and predictors of relapse in Merkel cell carcinoma: Results from a population-based study.

BACKGROUND AND PURPOSE: Prospective data evaluating the role of adjuvant radiotherapy (RT) for Merkel Cell Carcinoma(MCC) is lacking. To better understand the efficacy of adjuvant RT, a population-based patterns of failure study was conducted. METHODS: We identified MCC patients treated from 1988 to 2018.Primary outcome measures were recurrence-free survival (RFS), overall survival (OS) and MCC-specific survival (MCC-SS). Charlson Co-morbidity Index (CCI) was also calculated. RESULTS: 217 patients with mean age 79 (range: 33-96) were analyzed. The median follow-up was 40 months. Treatments were: surgery(S) alone (n = 101, 45%) or S + RT(n = 116, 55%).Local recurrence (LR) was low in stage I (n = 6, 6.5%) with clear margin of ≥1 cm, negative sentinel lymph node biopsy (SLNB) without high-risk factors, irrespective of adjuvant RT. Tumor size ≥ 2 cm (HR:2.95; p = 0.024) and immunosuppression(HR:3.98; p = 0.001) were associated with high risk of nodal failure. Adjuvant RT was associated with significant reduction in regional failure (HR:0.36; p = 0.002). Distant metastases (DM) were infrequent in stage I (4/90) and stage II (4/34), compared to stage III (32/93). Adjuvant RT improvedRFS but did not influence MCC-SS and OS. CCI was a significant predictor of OS. CONCLUSIONS: Adjuvant RT improvedRFS, withoutimpact on MCC-SS and OS. Co-morbidity rather than RT influenced OS. Adjuvant RT may be avoided instage I patients with negative SLNB and no associated high-risk factors. Prophylactic RNI could be considered in stage II with high risk features, inspite of negative SLNB. Stage III patients benefited from adjuvant RNI, but no impact on prevention of DM.

Forensic discrimination of lipsticks using visible and attenuated total reflectance infrared spectroscopy.

Lipstick traces may be encountered in forensic investigations as traces left on clothing, drinkware, tissue papers or other surfaces. However, their probative value is limited by the discriminatory power and destructiveness of existing analysis schemes. This work employed analytical spectroscopy with chemometrics to provide objective and non-destructive characterisation of lipsticks for forensic purposes. 22 red-shaded and 18 nude-shaded lipsticks were analysed using visible absorbance and diffuse reflectance spectroscopy, as well as attenuated total reflectance Fourier transform infrared spectroscopy. Principal component analysis readily distinguished most samples based on their spectral profiles, with subsequent models yielding discrimination accuracies exceeding 94% for each spectroscopic mode. This could provide a greater level of confidence when conducting 'questioned versus known' comparisons of similar lipsticks. Further testing using external validation sets produced identification accuracies of 73-100 %, which may allow investigative leads to be more readily obtained from recovered lipstick traces.
