Voices have been increasing in the last years, demanding the right of men to choose time and way of ending his life, thus asking consequently the liberty for mankind of killing themselves. The most important of these ideas are explained in connection with their philosophical, psychological and sociological background and confronted with the results of modern suicide research. The outcome of this review gives, however, no reason for changes in the previous and successful ways of suicide prevention. 相似文献

Definitions and classification schemes for suicide attempts vary widely among studies, introducing conceptual, methodological, and clinical problems. We tested the importance of the intent to die criterion by comparing self-injurers with intent to die, suicide attempters, and those who self-injured not to die but to communicate with others, suicide gesturers, using data from the National Comorbidity Survey (n = 5,877). Suicide attempters (prevalence = 2.7%) differed from suicide gesturers (prevalence = 1.9%) and were characterized by male gender, fewer years of education, residence in the southern and western United States; psychiatric diagnoses including depressive, impulsive, and aggressive symptoms; comorbidity; and history of multiple physical and sexual assaults. It is possible and useful to distinguish between self-injurers on the basis of intent to die. (PsycINFO Database Record (c) 2010 APA, all rights reserved) 相似文献

The purpose of this prospective, naturalistic study was to examine the relationships between suicide attempts and contemporaneous psychiatric disorders, and developmental changes in these relationships from adolescence to young adulthood. The sample consisted of 180 adolescents, 12–19 years of age at hospitalization, repeatedly assessed for up to 13 years (n = 1,825 assessments). Semistructured psychiatric diagnostic instruments were administered at repeated assessments to assess psychiatric disorders and suicide attempts. After controlling for demographic variables and prehospitalization suicide attempts, most contemporaneous psychiatric disorders (major depressive disorder [MDD], dysthymic disorder, generalized anxiety disorder [GAD], panic disorder, attention-deficit/hyperactivity disorder [AD/HD], conduct disorder, and substance use disorder [SUD]) were related to increased risk of attempts. The relationship between suicide attempts and MDD, GAD, AD/HD, and SUD strengthened as participants got older. MDD, dysthymic disorder, GAD, and panic disorder were more commonly associated with repeat than 1st-time suicide attempts. In sum, most major psychiatric disorders are associated with increased risk for suicide attempts, but the strength of the relationships between these disorders and attempts changes over the course of development.

The recent publication of core competencies in suicide risk assessment and management (Suicide Prevention Resource Center, 2006) and the American Psychiatric Association's (2003) practice guidelines have raised concerns about how best to address these issues in clinical supervision of trainees. This article reviews the identified core competencies, addresses implications for supervision of trainees, and provides a general framework for applicable strategies for the supervision process to facilitate clinical skill development and refinement.

Sudden cardiac death is defined as natural death due to cardiac causes, heralded by abrupt loss of consciousness within one hour after the onset of symptoms. The mechanisms are the following: 1. ventricular fibrillation, 2. ventricular tachycardia and flutter with subsequent ventricular fibrillation, 3. torsade de pointe, 4. bradyarrhythmias and asystolic arrest. White the main risk factor is the presence of coronary artery disease, any organic or functional disease of the heart can predispose for sudden cardiac death. To evaluate the risk of sudden cardiac death noninvasive (Holter, echocardiography, exercise test and signal averaged (ECG) and often invasive (electrophysiological study) tests are necessary. The therapy is based on drugs (mainly beta blockers and amiodarone), coronary revascularization, catheter ablation techniques and the implantation of a cardioverter defibrillator; the latter appears to be the most promising approach. 相似文献

We report preliminary findings of the first-ever study testing a 16-week course of interpersonal psychotherapy (IPT) modified for older outpatients at elevated risk for suicide. Participants were referred from inpatient and outpatient medicine and mental health services. Psychotherapy sessions took place in a therapist’s office in a teaching hospital. Twelve adults 60 years or older (M = 70.5, SD = 6.1) with current thoughts of suicide (suicide ideation), a wish to die (death ideation), or with recent self-injurious behavior were recruited into weekly sessions of IPT; 1 participant was subsequently excluded due to severe cognitive impairment. Participants completed measures of suicide ideation, death ideation, and depressive symptom severity at pretreatment, midtreatment, posttreatment, and at 3-month follow-up periods, and measures of therapeutic process variables. Preliminary findings of this uncontrolled pretreatment/posttreatment study support the feasibility of recruiting and retaining older adults at risk for suicide into psychotherapy research and suggest that adapted IPT is tolerable and safe. Findings indicate a substantial reduction in participant suicide ideation, death ideation, and depressive symptoms; controlled trials are needed to further evaluate these findings. We discuss implications for clinical care with at-risk older adults. (PsycINFO Database Record (c) 2010 APA, all rights reserved) 相似文献

The assessment of potential for suicide among patients with a diagnosis of alcohol dependence has consistently been a dilemma for clinicians. Specifically, a problem for both clinicians and researchers has been determining what risk factors distinguish patients with suicidal ideation from those that are in danger of completed suicide. Identifying what clinicians who specialize in substance abuse view as critical in the assessment and treatment of suicidal patients is a first step in gaining a greater understanding of suicide risk within an alcoholic population. The views of these clinicians are presented and compared with empirical findings on the subject. (PsycINFO Database Record (c) 2010 APA, all rights reserved) 相似文献

The assessment of risk for suicide in patients with major depression is a difficult task for professional psychologists. Not only is prediction itself a nearly impossible feat, but the literature is full of risk factors to which one should attend. Which of these factors are specific to the patient sitting before you? By combining clinical and empirical literature of major depression-specific risk factors with the reported behaviors of practicing psychologists, the authors present critical factors for assessing suicidal risk.

Withdrawal from dialysis has been a significant cause of mortality among dialysis patients, accounting for 6 to 22% of deaths. Since 1990, a new death notification form has allowed more detailed analyses of withdrawal from dialysis separate from causes of death. Using the U.S. Renal Data System data base, this study examined 116,829 deaths in adult patients from 1990 to 1995. Adjusted odds ratios were calculated for the risk of withdrawal using logistic regression. Adjustments included age at death, ethnicity, gender, cause of death, primary cause of end-stage renal disease, time on dialysis, and dialysis modality. In addition, odds ratios of withdrawal were calculated for deaths in patients who started dialysis after age 65. Death was preceded by withdrawal significantly more frequently in women than in men, more than twice as frequently in Caucasians than in African-Americans or Asians, and more frequently in older than in younger age groups. Patients who died of chronic diseases (e.g., dementia, malignancy) were much more likely to withdraw before death, whereas patients who died from more acute causes (e.g., coronary artery disease) were less likely to withdraw before death. It is concluded that patients who are Caucasian, female, older, or die of chronic or progressive diseases are more likely to withdraw from dialysis before death. The ethnic and gender differences in withdrawal do not appear to have a medical explanation from this analysis. Further research along sociologic lines is needed to better explain the differences in withdrawal from chronic dialysis. 相似文献

OBJECTIVE: Gestational diabetes is associated with increased risk of developing noninsulin-dependent diabetes (NIDDM) later in life. By the time that a diagnosis of NIDDM is established, functional disturbances in the vascular system may be observed. This study was planned to assess macro- and microvascular function in nonpregnant women without signs of diabetes two to four years after a pregnancy complicated with gestational diabetes. DESIGN: Cross-sectional study. SETTING: Vascular research laboratory in the obstetric unit of a university hospital. PARTICIPANTS: Seventeen nonpregnant, healthy women with a history of gestational diabetes and 20 nonpregnant control women of similar age without previous diabetes. METHODS: For quantification of the mechanical properties in large arterial vessels the wall movements of the abdominal aorta and left common carotid artery were recorded with an ultrasonic tracking system. Microvascular perfusion in the skin of the hand and foot was recorded by a laser Doppler technique to assess the vasodilatory response induced by transcutaneous acetylcholine. RESULTS: Women in the gestational diabetes group showed evidence of increased wall stiffness in the common carotid artery and a lower maximum incremental velocity of the pulsatile vessel diameter change in both aorta and carotid artery compared with controls. Acetylcholine induced vasodilatation in both hand and foot was lower in women with previous gestational diabetes compared with controls. CONCLUSION: Abnormal vascular function was found in asymptomatic women with a history of gestational diabetes. It is speculated that these abnormalities might be early evidence of vascular complications associated with subsequent NIDDM. 相似文献

Patients who die within the first 90 days after beginning dialysis are not included in mortality rates and may be absent from incidence counts. To identify factors associated with mortality within 3 months of the initiation of dialysis for ESRD and to estimate the impact of early deaths on ESRD incidence and mortality rates, this study investigated 15,245 patients who began dialysis in Georgia, North Carolina, and South Carolina over a 5-yr period. Data were collected by dialysis facility staff and reported to an ESRD registry. Six percent of all new patients died within 90 days of dialysis initiation (32% of all deaths occurring in the first year of treatment). Characteristics independently associated with increased risk of early death included older age, white race, male gender, physical and nutritional impairment, smoking, and the presence of cancer, congestive heart failure, clinical depression, and history of myocardial infarction. Depending on race-gender group, age-adjusted mortality rates based on this cohort were underestimated by 3 to 12% when patients who died early were excluded. These results suggest that certain patient characteristics-some potentially modifiable-confer increased risk of early death, and that the systematic exclusion of patients who die early from the U.S. national registry substantially influences ESRD mortality rates. 相似文献

The objectives of this study were to determine 1) the effectiveness of calcium chloride when injected later than 2 d postmortem, 2) the effect of extended postinjection aging time, and 3) the tenderness response curve in calcium chloride-treated beef. In Exp. 1, the longissimus thoracis et lumborum was injected on either d 2 or 14 postmortem with 5% by weight of a 200 mM calcium chloride solution. Samples were aged (1 degree C) either 7 or 35 d after injection. The uninjected control longissimus from the contralateral side was aged for 9, 21, 37, or 49 d. In Exp. 2, the longissimus thoracis et lumborum was injected on d 2 postmortem with 5% by weight of a 200 m x M calcium chloride solution then sampled for shear force on d 1, 2, 6, 8, 12, and 14 after injection. Calcium chloride injection, regardless of injection time or postinjection aging time, had higher (P < .05) sensory tenderness rating than control with the same total aging time (5.2, 5.5, 5.8, and 6.1 vs 4.3, 4.8, 5.1, and 5.3, respectively). Calcium chloride injection at d 14 reduced shear force (.7 kg) and increased tenderness rating (.7 units) as effectively (P > .05) as injection at d 2 (1.2 kg and .8 units, respectively). Calcium chloride-injected steaks had higher (P < .05) juiciness ratings than control steaks. Postrigor calcium chloride injection reduced (P < .05) shear force within 1 d after injection and resulted in more tender meat through 14 d after injection. Extended postinjection aging (35 d) had little effect on color display stability. Calcium activated tenderization can be applied as late as 14 d postmortem and will reduce the occurrence of tough meat if aging is limited. 相似文献

In 102 consecutive prospectively identified patients with subarachnoid haemorrhage (SAH) we have analysed the severity of the initial haemorrhage and the direct and indirect effects of adverse factors on outcome. The data we recorded included delay in diagnosis, risk groups, Doppler measurements, angiographic findings, surgical events and outcome at 1 year. By using a temporal graphical chain model, the associations between all variables and possible causal pathways were statistically determined. The severity of the initial haemorrhage, as determined by means of a clinical assessment and CT scanning, allowed low-, medium- and high-risk patient groups and a statistically predictable outcome to be identified. The overall management mortality was 13.7% at 1 year; 70.6% had a favourable outcome and 15.7% were severely disabled. Outcome was directly associated with risk group (p = 0.0038) and rebleeding (p = 0.0000). Delayed diagnosis led to a poorer outcome (p = 0.014)--an indirect association probably due to rebleeding. Adverse surgical events led to a significantly poorer outcome in high-risk patients. No significant relationship was found either between age and risk group (p = 0.7784) or between age and outcome (p = 0.6418). Preoperative clinical (WFNS) grade was unreliable in predicting outcome. It is the particular risk group, determined by the initial SAH, that indicates the individual patient's outcome. Management strategies can reduce preventable adverse events such diagnostic delay and rebleeding. Future studies should stratify patients according to risk group, delay in diagnosis and rebleeding in order to enable a clearer comparison to be made of treatment methods. 相似文献

The study included 65 patients--42 males and 23 females aged 67 +/- 17 with the diabetic foot syndrome. They were divided into 2 groups: those who underwent amputation (25 patients) and 40 who were treated conservatively. Amputations were preceded most frequently by ulceration (17 cases), phlegmona (5 cases) or dry necrosis (3 cases). The high percentage of amputations in the studied patients could be explained, at least in part, by poor general condition and advanced local changes. In the group of patients, who underwent amputation--in relation to those treated conservatively a decrease in filtration function was found (46.0 +/- 24.3 vs 89.5 +/- 26.2) and a higher percentage in the prevalence of microalbuminuria or proteinuria (80% vs 45%) as well as a higher percentage of cigarettes smokers in this group (72% vs 40%). The majority of the studied patients was characterized by poor education, lack of self-control of glycaemia, no efficient metabolic control of diabetes, measured by glycated haemoglobin and the presence of neuropathy and retinopathy. In addition, in 4 patients among the whole studied group (including 1 patient who underwent amputation), diabetes was newly diagnosed. These results indicate the necessity of improving education, early diagnosis of insulin independent diabetes, more frequent foot examinations and the elimination of amputation risk factors. Prophylaxis of diabetes foot associated with the proper treatment of diabetes is a necessary condition for decreasing of the amputation rate according to St. Vincent Declaration. 相似文献
