[Intentions and behaviors of risky drug consumption in users at the rehabilitation centers in Valencia].

A study was made of the factors associated with high-risk behavior and intention to change among 126 intravenous drug users (IVDU) seen at drug treatment centers. Needle-sharing in the last month was associated with intravenous cocaine use, whereas sharing water or drug preparations was associated with variables related to the level of instruction or the reduction in the number of syringes shared in the last month. The intention to abandon high-risk behavior was not associated with the information, attitudes, or norms of the group, but was associated with the perception of personal capacity for reducing high-risk behavior. Finally, the importance and applications of these results in health counseling for IVDUs is discussed.

Obsessional phenomena and the concept of intentionality.

Obsessional phenomena exist in a variety of character types. The particular phenomena may be of limited value in total personality assessment. Some speculative links are made between obsessional phenomena and preanal developmental steps. It is suggested that the concept of intentionality of thought and action be examined in these patients to distinguish obsessionals with core conflicts that are primarily neurotic and triadic, from those with more significant, earlier difficulty in the oral period. The concept of intentionality is related to self-object distinction, the use of projections, the sense of self, pathologic ego-superego condensation, and the existence of the ability to tolerate and recognize aggressiveness within. More accurate and rapid diagnostic distinction among obsessionals has implications for different treatment approaches.

Intentional replantation for iatrogenic perforation of the furcation: a case report.

Intentional replantation is an accepted endodontic procedure for treatment of teeth in which conventional surgical endodontic treatment is contraindicated. This article presents a rare case of intentional replantation of a mandibular molar that had severe periodontal destruction resulting from iatrogenic perforation of the furcation. A 17-month follow-up evaluation revealed an asymptomatic and functional tooth with no radiographic signs of pathosis. The favorable results obtained might be attributed to the preservation of the vitality of the periodontal ligament; the absence of damaging pressure during extraction; the minimal extraoral treatment time; the use of nonrigid splinting; and the immediate repair of the perforation during a one-visit endodontic procedure. The results obtained with this tooth may indicate the possibility of a successful surgical technique for this otherwise hopeless complication of endodontic therapy.

[Significance of intentional weight loss on health].

The aim of the present study was critically to review how intentional weight loss in overweight and obesity influences mortality. No randomized weight loss intervention trial has included mortality as an end-point. However, even minor weight loss causes beneficial changes in risk factors for cardiovascular disease, whereas the vast majority of observational studies have linked weight loss to excess mortality. Most observational studies do not have information on intentionality of weight loss and suffer from other methodological limitations making inferences from these studies difficult. Given the available observational evidence, the possibility that intended weight loss may cause some increased mortality cannot be excluded. However, considering the totality of the evidence on effects of intended weight loss among overweight and obese subjects, there may be other benefits, such as: psycho-social and physical well-being, risk factor improvement, decreased morbidity, and in certain high-risk subgroups decreased mortality. Treatment of obesity is therefore recommended, particularly in the presence of risk factors or complications.

Prediction of suicide intent in aboriginal and non-aboriginal adolescent inpatients: a research note.

The relationship among depressive symptoms, anxiety, hopelessness, and suicidal intent was explored in a group of 77 adolescents who had been hospitalized after attempting suicide. Regression analyses indicated that hopelessness was the only significant predictor of suicide intent in Caucasian patients, and depressed mood was the only significant predictor in the Aboriginal group. Clinicians should be aware that measures of hopelessness may be of limited value in assessing suicidal risk in Aboriginal adolescents.

Intention to relocate to the United States.

OBJECTIVES: To gain insight into family medicine residents' attitudes toward relocating to the United States and to examine factors influencing their decisions. DESIGN: Cross-sectional mailed survey. SETTING: University of Toronto family medicine program. PARTICIPANTS: First- and second-year residents in the academic year 1995 to 1996. A 74.6% response rate (144 of 193 residents) was achieved. MAIN OUTCOME MEASURES: Intention to relocate to the United States. Degree of importance of 11 motivational factors in residents' decisions to relocate. RESULTS: In this survey, 48% of residents reported they intended to relocate to the United States, but only 17% recalled expecting to relocate before Ontario's introduction of geographic billing restriction legislation. Geographic billing restriction was the motivational factor most residents (86.8%) considered very important in their decision-making process. The two factors potentially predicting US relocation were finance and climate. CONCLUSIONS: Many factors influence family medicine residents' intention to relocate to the United States. Geographic billing restriction was the most significant motivational factor, and its introduction has likely precipitated a marked shift in residents' attitudes favouring US relocation.

Distant intentionality and healing: assessing the evidence.

Since the 1950s, researchers have attempted to understand reports of distant or "psychic" healing, developing experimental protocols that test the distant healing hypothesis by measuring biological changes in a target system while ruling out suggestion or self-regulation as counterexplanations. This article provides a brief overview of these "healing analog" experiments. It also provides a summary and meta-analysis of 30 formal experiments in which self-reported healers, "psychics," and other self-selected volunteers attempted to influence autonomic nervous system activity in a distant person. Results across the experiments showed a significant and characteristic variation during distant intentionality periods, compared with randomly interspersed control periods. Possible alternative explanations for the reported effects are considered. Finally the implications of distant intentionality are discussed for an understanding of the possible mechanisms of distant healing, the nature of the mind-body relationship, and the role of consciousness in the physical world.

Prostate cancer screening in the midst of controversy: Canadian men's knowledge, beliefs, utilization, and future intentions.

Despite controversy about prostate cancer screening, administrative data show that the use of prostate specific antigen (PSA) testing in Canada has increased. This study sought to determine awareness and knowledge of prostate cancer and screening, use to date, and future intentions to have a digital rectal examination (DRE) and PSA test among Canadian men aged 40 and over. Data were collected through a Canada-wide cross-sectional random digit dial telephone survey of 629 men. Awareness of DRE and PSA, use to date, and future intended use varied with age and education. Although only 9% of respondents had had PSA testing for screening, future intentions to undergo this test were higher than use to date. Knowledge of prostate cancer and screening controversies was low, and men received more information about PSA from the media than from doctors. Men would, therefore, benefit from age- and education-specific information regarding the factors to consider in making an informed choice about prostate cancer screening.

A Bayesian framework for intent-to-treat analysis with missing data.

In longitudinal clinical trials, one analysis of interest is an intention-to-treat analysis, which groups subjects according to the randomized treatment regardless of whether they stayed on that treatment or not. When in addition to going off the randomized treatment subjects may also drop out of the study and be lost to follow-up, it is unclear what an intention-to-treat analysis should be. If measurements are made after treatment drop-out on a random sample of subjects who drop the treatment, then Hogan and Laird (1996, Biometrics 52, 1002-1017) present a random effects model, well suited to this type of analysis, which fits a two-piece linear spline to the data with the knot at the time the assigned treatment is dropped. This article presents a Bayesian approach to fitting a similar two-piece linear spline model and shows how the model can be applied to data that have no off-treatment observations.

[Effect of the presentation of results from clinical trials on the intention to prescribing: relativity of the relative risk].

OBJECTIVE: To determine if the methods of reporting results of clinical trials affects the physician views on prescribing. DESIGN: Analysis of responses, from a convenience sample of primary care physicians, of one teaching exercise on prescribing intention which showed 5 different methods of reporting results: relative risk reduction (RRR), absolute risk reduction, the percent of event free patients, the number needed to treat (NNT) and RRR and mortality. SETTING: Curses of clinical management in Valencia and Barcelona. RESULTS: The willingness to prescribe was significantly influenced by the way in which data were presented, being major when they were showed as RRR and minor when mortality was added. CONCLUSIONS: The method of reporting trial results has an important influence on the prescribing intention. The reporting of clinical trial results, and their abstracts or citations, should be include the NNT and negative results, for avoiding a subjective bias of treatment effect magnification.

Crown amputation with intentional root retention for advanced feline resorptive lesions--a clinical study.

Whole tooth extraction is generally considered to be the treatment of choice for teeth with advanced feline external odontoclastic resorptive lesions. These teeth often have both a weakened, brittle crown and radicular ankylosis. These two factors cause frustration and sometimes complications during attempts at extraction. This study investigated the alternative of intentionally leaving part or all of non-pathologic tooth roots in situ to prevent iatrogenic trauma to the patient, loss of alveolar bone, and prolonged healing of surgical defects. Fifty one roots from 23 teeth were radiographed 5-36 months following elective root retention; continued resorption without surrounding bony reaction was seen in almost all cases. In one cat, the roots retained normal periodontal ligament one year later, and in another cat that developed severe stomatitis, the intentionally retained roots were extracted at the same time that the remaining molar teeth were extracted.

Intention and knowledge in preschoolers' conception of pretend.

Experiments 1 and 2 investigated 3- and 4-year-olds' understanding of the intended nature of pretend behaviors by testing their ability to distinguish between involuntary behaviors and the same behaviors emitted intentionally through acts of pretend. Four-year-olds' high rate of passing showed that (1) they understood intention as a mental cause of action and (2) they construed pretend behaviors mentalistically. Experiment 3 used the same contrastive procedure to examine Lillard's contention that 4-year-olds do not understand the knowledge conditions and hence the mental representational component of pretend actions. Whereas nearly all of the 5-year-olds understood that an agent who did not know of a specific animal could not be pretending to be that animal, 4-year-olds systematically associated ignorance with pretend. On the basis of the combined findings of the present experiments, and other research showing a mentalistic understanding of pretense by the age of 3 or 4, it was concluded that the specific reasoning requirements of Lillard's tasks resulted in an underestimation of children's appreciation of the mental features of pretend.

Intention-to-treat analysis of 200 patients with rheumatoid arthritis 12 years after random allocation to either sulfasalazine or penicillamine.

OBJECTIVE: To assess existing disease modifying antirheumatic drugs (DMARD) using a strategy aiming for sustained suppression of inflammation. METHODS: We conducted intention-to-treat analysis of open randomized study [sulfasalazine (SASP) or penicillamine (PEN)], followup 12 years, conducted at specialist rheumatology clinics in Glasgow, Scotland. Subjects were 200 patients with rheumatoid arthritis (RA) with established disease. In this "true to life" approach, comorbidity was not an exclusion criterion unless it prejudiced assessment of drug toxicity. The main outcome measure was the Health Assessment Questionnaire (HAQ) functional score. RESULTS: Over 12 year followup 95 (47.5%) patients died; this was the commonest reason for study groups being unfulfilled. There was one drug related death (methotrexate). Patients who were socially disadvantaged were more likely to die prematurely. HAQ did not deteriorate significantly in those who continued taking their original DMARD, or in the SASP intention-to-treat group over 12 years. Sustained suppression of disease activity was possible in the entire group available for followup at 12 years. Most toxicity occurred early and no unexpected side effects were observed. CONCLUSION: High premature mortality in RA was confirmed and an association between mortality and deprivation was demonstrated. Sustained reduction in acute phase response was possible using sequential single DMARD. This study provides useful baseline and longterm information against which to evaluate combination therapy or new agents.

[The relationship between the perceived threat of environmental problems and the formation of action intentions].

The results of a study using questionnaires at two measuring points in high schools in North Germany are reported and discussed. This article analyzes the students' reasons and motivation for more or less environmentally friendly behavior. An integrated theoretical concept of motivation for human action formed the theoretical basis. The action genesis process was subdivided into the phases of forming motives, intentions and volition. Following a presentation of this theoretical concept and its definition with regard to competing and compatible theoretical hypotheses, the methodological procedure is described whereby the various motivation structures of the pupils questioned were analyzed. Mixed distribution models were used which allow modelling of complex multivariate relationships (latent class analysis and mixed Rasch models). The results show strong positive relationships among the variables of the motivation, the intention and the volition phases, but with isolated area-specific motivation patterns and moderator effects of certain cognitive variables.

[Intention to kill--the deciding criterion between allowed and prohibited assisted euthanasia].

The difference between the allowed and forbidden euthanasia is--on account of the dominant opinion--the criterion of acting and forbearance. It is not punishable to let a terminally ill patient die, but it is punishable to kill a patient on purpose. This distinctive mark is not forcible, because the acting is similar to the forbearance, when the actor has a guaranter's obligation--this is always the case between a doctor and his patient--and it is questionable, if the stopping of apparatuses for support of life is a kind of acting or forbearance. To overcome this dilemma, the author proposes to establish the distinctive mark of "intention to kill" in the law. Then the euthanasia is a punishable act if the actor or the person, who forbears, practices euthanasia with the intention to kill the patient. The euthanasia is not punishable, however, if the euthanasia overwhelms the blockade of dying or softens the pains.

Intention-based critiquing of guideline-oriented medical care.

We present a methodology and tool for providing retrospective review and critiquing of guideline-based medical care given to patients. We show how our guideline representation language, Asbru, which supports the use of physicians intentions in addition to physician's actions, allows us to compare the care given to a patient at the level of the intention to treat in addition to the more detailed plan carried out. We have developed an algorithm based on this representation for retrospective quality assessment of guideline-based care. Our method takes the physician's and institution's preferences and policies into account in explaining or justifying physician deviations from the recommendations of a guideline.

Voluntariness, intention, and the defence of mental disorder: toward a rational approach.

This article addresses how mental disorder may be used in common law countries to negate the requirements of voluntariness and intention in serious criminal offences as well as to provide the basis for current versions of the insanity defence. The notion that mental disorder can cause conduct to become completely involuntary or unintentional is questionable, given current thinking in the behavioral sciences. This article argues that different forms of mental disorder should be subsumed within a separate defence of mental disorder. Providing that a range of dispositional options is available, the law in this complex area would be simplified and brought into line with current psychological notions of goal-directed behavior.

[Palliative chemotherapy and CUP-syndrome: medical intentions versus patients' attitudes in decision making].

The following case report is about a 55 year old male patient with CUP-syndrome. After developing a malignant bowel obstruction he received five cycles of a palliative chemotherapy with oxaliplatin and irinotecan. The focus is on medical intentions and goals concerning palliative chemotherapy and on discussing patients' attitudes towards chemotherapy. Communication is identified as fundamental skill in shared decision making. On the one hand it improves Patients' satisfaction and palliative care and on the other hand it reduces psychological and existential suffering. In tumors of unknown primary site regimens with different combinations of Platin, Taxol, Etoposide, Irinotecan and Gemcitabine showed responses up to 46% and a survival benefit with an overall median survival up to 12 months and even long term survival.
