A Machine Learning Approach to Identifying the Thought Markers of Suicidal Subjects: A Prospective Multicenter Trial 下载免费PDF全文
John P. Pestian PhD Michael Sorter MD Brian Connolly PhD Kevin Bretonnel Cohen PhD Cheryl McCullumsmith MD PhD Jeffry T. Gee MD Louis‐Philippe Morency PhD Stefan Scherer PhD Lesley Rohlfs MS the STM Research Group 《Suicide & life-threatening behavior》2017,47(1):112-121
Death by suicide demonstrates profound personal suffering and societal failure. While basic sciences provide the opportunity to understand biological markers related to suicide, computer science provides opportunities to understand suicide thought markers. In this novel prospective, multimodal, multicenter, mixed demographic study, we used machine learning to measure and fuse two classes of suicidal thought markers: verbal and nonverbal. Machine learning algorithms were used with the subjects’ words and vocal characteristics to classify 379 subjects recruited from two academic medical centers and a rural community hospital into one of three groups: suicidal, mentally ill but not suicidal, or controls. By combining linguistic and acoustic characteristics, subjects could be classified into one of the three groups with up to 85% accuracy. The results provide insight into how advanced technology can be used for suicide assessment and prevention. 相似文献

The purpose of this investigation was to study the effects of Medical Resonance Therapy Music (MRT-Music) upon autonomous
innervation of cerebral arteries by examining slow spontaneous oscillations of cerebral blood flow (SSO) using transcranial
Doppler ultrasound (TCD). TCD detects SSO with 3–9 cycles per minute (M-waves) and 0.5–2 cycles per minute (B-waves). The
SSO are caused by rhythmic diameter changes of the medium and small cerebral arteries. Six patients aged 24–65 years suffering
from tension headache were treated with MRT-Music. Twelve additional patients were examined with TCD only to register SSO
for further spectral analysis.
After fast Fourier transformation four groups of peaks were registered on the SSO spectra, divided into four rhythms: A. 0.0–0.02
Hz, B. 0.02–0.033 Hz, C. 0.06–0.09 Hz, D. 0.09–0.15 Hz and an intermediate diapason of 0.034–0.059 Hz.
Spectral analysis of the SSO showed changes between initial and final amplitude peaks in all patients. In contrast to A-,
B-and D-rhythms, the reduction of peaks in the C-diapason was statistically significant (31–60%, P 3D0.04, CI 3D95%) for patients
treated with MRT-Music. All patients treated with the MRT-Music reported a relief of headache while and after treatment. 相似文献

Music is an ancient method for healing. In the year 550 B.C., Pythagoras from Greece developed a concept for the use of music
in medicine, esteeming music higher than many other medical treatments. The Medical Resonance Therapy Music (MRT-Music) of
the German classical composer and musicologist Peter Huebner is built on this concept of Pythagorean music medicine. Its therapeutic
effect may be best explained by the natural phenomenon of resonance between the harmony laws of the microcosm of music and
the biological laws of the body. Results received after application of MRT-Music indicate multiple positive effects on the
organism of pregnant women both with a healthy pregnancy as with a pathologic one, reducing the rate of premature births very
effectively. Furthermore, MRT-Music came out to be an effective method in the complex therapy of late gestoses and a nearly
irreplaceable method for preoperative preparation of pregnant woman for caesarean section. It demonstrated a powerful anti-stress
effect and allowd to reduce the amount of administered pain-killers to pregnant women by the factor 1.5 to 2.0 thus reducing
the negative pharmacological load to the foetus. It furthermore reduced labour time and shortened hospital stay. It helped
to create optimal conditions for the course of pregnancy and heightened pain sensitivity threshold by means of improving the
functional, hormonal, and psycho-emotional conditions of pregnant and lying-in women. Thus, the labour process became more
natural, the delivery non-traumatic, and motherhood more happy and safe. 相似文献

Little is known about accurate prevalence and associated factors of deliberate self‐harm (DSH) among adolescents in Asian countries. In this study, the prevalence and associated factors of DSH among adolescents in Japan were examined. Data were derived from a cross‐sectional survey using an anonymous self‐report questionnaire and enrolling 8,620 adolescents aged 12–15 and 9,484 aged 15–18. DSH in the previous 12 months was reported by 3.3% (95% CI, 2.9–3.7) of junior and 4.3% (3.9%–4.7%) of senior high school respondents. The prevalence was more than four times as high among girls as among boys for both age groups. DSH was further strongly associated with having suicidal thoughts, having depression/anxiety symptoms, and having used recreational drugs. These associated factors were similar for both sexes and for both older and younger teenagers. A substantial minority of adolescents present with DSH, even among those aged 12–15. The prevalence of DSH in Japan was in the lower ranges of those reported for Western countries. The identified associated factors were not dissimilar from those reported in the West. 相似文献

Using the metaphor of “a long run’ to describe our progress in suicidology, the author looks back to discuss important concepts that have become well established, such as clues to suicide, ambivalence, crisis services, suicide consultations, and psychological autopsies. An example is the psychological autopsy of Marilyn Monroe. Follow-up studies of crisis center clients have indicated that chronically suicidal clients are at the greatest risk of suicide. Recommendations for the long-term treatment of such patients are provided. Research on youth suicide is reported. Finally, the author looks ahead toward new developments in training and treatment. 相似文献

To determine changes in rates of drug ingestions in 10–14 year old children in our country, a retrospective chart review of 10–14 year olds hospitalized for drug ingestion between 1993–1995 and 2000–2004 was performed. Odds ratios and Chi‐square were used for analyses. From 1993–1995 there were 92.8 ingestions/100,000 children/year; from 2000–2004 there were 63.3 ingestions/100,000 children/year. More males ingested in 2000–2004 than 1993–1995 (26.3% vs. 14.2% O.R. 2.15 [1.19, 3.92]). More patients took psychiatric medications in 2000–2004 than 1993–1995 (38.9% vs. 27.0%, O.R. 1.72 [1.06, 2.80]). More patients ingested SSRIs in 2000–2004 than 1993–1995; fewer ingested tricyclics. Hospitalization rates for drug ingestions have decreased. There has been a change in drug ingested, and more males are ingesting drugs. 相似文献

Different methods of poisoning used by individuals with the diagnosis of parasuicide admitted to the Loghman Hospital, Tehran, from 2000 to 2004 were investigated, with particular focus on gender and age differences. Drugs, pesticides, and other agricultural chemicals (women: 12.7%, men: 9%) were the most commonly used methods. In males, the percentage of use of drugs increased with age, but the frequency of pesticides use decreased with age. In females, drugs were most often used in the youngest age group, whereas the use of pesticides was lowest in the youngest age category. Females outnumbered males, especially in the youngest age group of 10 to 19 years olds. Drugs and pesticides were the substances used most often for parasuicide in each age group regardless of gender. 相似文献

In a sample of young adult Australians, those who had had suicidal ideation but who did not acknowledge ever having had it when asked 4 years later, were experiencing better mental health, as demonstrated by significantly better functioning on a range of psychometric measures, than those who recalled it. These results are consistent with several recent reports and indicate that forgetting painful events such as suicidal ideation is an adaptive defense mechanism. This has implications in terms of therapy focusing on contemporaneous events and the future, rather than on the past. 相似文献
