Phonological awareness intervention for children with childhood apraxia of speech.

AIMS: To investigate the effectiveness of an integrated phonological awareness intervention to improve the speech production, phonological awareness and printed word decoding skills for three children with childhood apraxia of speech (CAS) aged 7;3, 6;3 and 6;10. The three children presented with severely delayed phonological awareness skills before intervention. METHODS & PROCEDURES: In consideration for the heterogeneity in the population with CAS, the study employed a multiple single-subject design with repeated measures. Baseline and post-intervention measures for speech, phonological awareness and decoding were compared. Each child received intervention for three 45-min sessions per week for 3 weeks (approximately 7 h of individual treatment). Sessions focused on developing phoneme awareness, linking graphemes to phonemes and providing opportunities for targeted speech production practice. Phonological awareness activities were linked with each child's speech production goals. OUTCOMES & RESULTS: Two participants significantly improved target speech and phonological awareness skills during intervention. These participants also generalized the phonological awareness skills from trained to untrained items and were able to transfer newly acquired knowledge to improved performance on a non-word reading task. CONCLUSIONS: The results suggest that integrated phonological awareness intervention may be an effective method simultaneously to treat speech production, phonological awareness and decoding skills in some children with CAS. The findings are discussed within the context of the phonological representational theory of CAS.

Peaceful awareness in patients with advanced cancer.

BACKGROUND: Previous studies have shown that prognostic awareness may be harmful to mental health yet beneficial for end of life care planning. The effects of prognostic awareness coupled with a sense of inner peace are unknown. METHODS: In the multisite, longitudinal Coping with Cancer Study, 280 patients with advanced cancer were interviewed at baseline. Patients defining themselves as "terminally ill" and/or "at peace" most days were paired with others on sociodemographic, mental health and advance care planning. Primary caregivers of deceased patients were interviewed 6 months postloss and compared on their physical and mental health and their perceptions of patients' end-of-life care and death. RESULTS: Overall, 17.5% of patients reported being both peaceful and aware. Peacefully aware patients had lower rates of psychological distress and higher rates of advance care planning (e.g., completing do-not-resuscitate [DNR] orders, advance care planning discussions with physicians) than those who were not peacefully aware. Additionally, peacefully aware patients had the highest overall quality of death as reported by their caretakers in a postmortem evaluation. Surviving caregivers of peacefully aware patients were more physically and mentally healthy 6 months postloss than caregivers of patients who were "aware" but not peaceful. CONCLUSIONS: Patients with advanced cancer who are peacefully aware have better mental health and quality of death outcomes, and their surviving caregivers have better bereavement outcomes. Peaceful awareness is associated with modifiable aspects of medical care (e.g., discussions about terminal treatment preferences).

Awareness with recall during general anesthesia: incidence and risk factors.

UNLABELLED: We studied the associated factors and incidence of awareness during general anesthesia and the nature of subsequent psychiatric disorders. Patients older than 12 yr undergoing surgery under general anesthesia in a secondary care hospital during 1 yr were included in the study. The doses of anesthetics were calculated for the patients with and without awareness. There were 4818 operations under general anesthesia; 2612 (54%) patients were interviewed. Ten (0.4% of those interviewed) patients were found to have undisputed awareness, and there were nine (0.3%) patients with possible awareness. The doses of isoflurane (P < 0.01) and propofol (P < 0.05) were smaller in patients with awareness. Five patients with awareness underwent a psychiatric evaluation. One patient experienced sleep disturbances afterward, but the other four patients did not have any after effects. In conclusion, awareness is a rare complication of general anesthesia associated with small doses of anesthetics. IMPLICATIONS: In an interview of 2612 patients after general anesthesia, 10 (0.4%) patients with awareness and 9 (0.3%) patients with possible awareness were found. A predisposing factor was small doses of the principal anesthetic. In a psychiatric interview, a large proportion of the patients with awareness were found to have suffered from depression in the past.

Reproductive health awareness of school-going, unmarried, rural adolescents.

OBJECTIVE: In 1996, India included Adolescent Health in Reproductive and Child Heatlh Programme. This Task-Force Study was planned to test the awareness level of adolescents regarding various reproductive health issues and to identify lacunae in knowledge, particularly in legal minimum age of marriage, number of children, male preference, contraceptive practices, about STIs /AIDS etc. METHODS: It was a multicentre study, done in rural co-education/higher secondary schools of 22 districts located in 14 states through Human Reproductive Research Centre (HRRC's) of the Indian Council of Medical Research (ICMR). A sample of 8453 school going adolescents (aged 10-19 years) was surveyed by means of open ended, self-administered questionnaires maintaining confidentiality. RESULTS: Mean age of adolescents was 14.3 +/- 3.4 years. Awareness of legal minimum age of marriage was present in more than half of adolescents. Attitude towards marriage beyond 21 years in boys and 18 years in girls was favorable. Mean number of children desired was 2.2 +/- 1.4. However, number of children desired by boys (2.2+/-1.6) was significantly more (p< 0.000) than those desired by girls (2.0+/-1.1). More boys (23.7%) than girls (9.4%) wanted three or more children with male preference. Only 19.8% of adolescents were aware of at least one method of contraception. Only two-fifth (39.5%) were aware of AIDS and less than one-fifth (18%) were aware of STDs and most of them thought it is same as AIDS. Awareness of at least one method of immunization was present in three-fifth (60.1%) of students. It was least for DPT (13.5%) and most (55%) were aware of polio only. Awareness of all Reproductive Health matters was more in boys than girls and more in late teens (15-19) than earlier teens (10-14). CONCLUSION: The study showed tremendous lacunae in awareness of all Reproductive Health (RH) matters. There is a need for evolving information, education, and communication strategies to focus on raising awareness on RH and gender related issues. A sociocultural research is needed to find the right kind of sexual health services for young girls and boys.

Partner awareness of the serostatus of HIV-seropositive men who have sex with men: impact on unprotected sexual behavior.

Prior research has provided conflicting evidence about the association between partner awareness of an HIV-seropositive person's serostatus and HIV transmission behavior via unprotected intercourse. The current study examined partner awareness of participant HIV-seropositive status and sexual behavior in a multiethnic sample of HIV-seropositive men who have sex with men. Most HIV-seropositive men reported that their primary partners are aware, and most reported that at least some non-primary partners are aware the participant was HIV-seropositive before first having sex. Partner awareness of participant HIV-serostatus was related to unprotected sexual behavior during the past 3 months in a non-linear fashion, as men with partners who were inconsistently aware had higher rates of unprotected receptive anal intercourse than men with partners who were consistently aware or consistently unaware. Men with partners who were inconsistently aware also had higher rates of insertive oral intercourse than men with partners who were consistently aware. However, there were no differences in HIV transmission risk behavior between men with partners who were consistently aware and men with partners who were consistently unaware a participant was HIV-seropositive.

Increased absenteeism from work among aware and treated hypertensive and hypercholesterolaemic patients.

AIM: The 'labelling hypothesis' was introduced on the basis of the observation that labelling subjects with blood pressure elevation as hypertensive was associated with an increase in sickness absence. In the Belstress I study this hypothesis was analysed in the same way for the possible influence on sick leave of labelling persons with elevated cholesterol as hypercholesterolaemic. METHODS AND RESULTS: The Belstress I cohort concerns a sample of more than 16,000 men and 5,000 women at work in 24 Belgian industries in various sectors. Baseline data were collected by questionnaire and clinical examination. Awareness was defined as answering positively to the question 'did a physician ever tell you that your blood pressure/serum cholesterol was too high?' Sick leave data were independently and objectively recorded during 1 year following the screening. Sick leave was treated in a dichotomous way whereby the event was defined as being in the highest quartile of the annual number of days of sick leave (10 days or more for men and 15 days or more for women) or as being in the highest quartile of the annual number of spells of sick leave (two spells or more for both sexes). Gender-specific logistic regression analyses were performed, with adjustment for a large set of covariates. A positive association was observed between both awareness of hypertension and awareness of hypercholesterolaemia and the various definitions of sick leave, in both sexes and after adjustment for different covariates. When dividing up aware subjects into treated versus untreated, we observed in men the highest sick leave incidence in aware and treated hypertensive patients as well as in aware and treated hypercholesterolaemic patients. In women findings were less consistent, probably due to the smaller sample size. When looking at cumulative effects by examining participants with both hypertension and hypercholesterolaemia and their level of awareness for one or both risk factors, a statistically significant gradient was noticed in men, with the highest sick leave incidence, whatever the definition, in men aware for both risk factors, followed by men aware for one. In women the same trends were observed, but no level of statistical significance was reached. CONCLUSION: Without being able to test the effect of 'labelling' as such, our study provides support for the association between awareness of two different coronary risk factors and incidence of sick leave. Probably a common mechanism is at the base of these findings. Further research is needed, in order to reduce potential negative effects of screening on human wellbeing as well as on productivity.

Crisis management during anaesthesia: awareness and anaesthesia.

BACKGROUND: Patient awareness during general anaesthesia has considerable potential for severe emotional distress in the patient as well as professional, personal, and financial consequences for the anaesthetist. OBJECTIVES: To examine the role of a previously described core algorithm "COVER ABCD-A SWIFT CHECK", supplemented by a specific sub-algorithm for awareness, in the detection and management of potential awareness in association with general anaesthesia. METHOD: The potential performance of this structured approach for each of the relevant incidents among the first 4000 reported to the Australian Incident Monitoring Study (AIMS) was compared with the actual management as reported by the anaesthetists involved. RESULTS: Of the first 4000 reports received by AIMS, there were 21 incidents of patient awareness under general anaesthesia, and 20 of patients being paralysed while awake from "syringe swaps" before induction of anaesthesia. In 12 of the 21 reports there was an obvious cause, most commonly a low concentration of volatile agent (8 of 12 reports). The AIMS "core" crisis management algorithm would have detected the cause of awareness in all of these cases. In nine reports the course of anaesthesia appeared unremarkable, and in these the algorithm would not have been expected to detect or prevent awareness. Volatile agent monitoring would have prevented some cases of awareness, as would bispectral index electroencephalographic (BIS) monitoring. The role of BIS monitoring is still contentious, but it should be considered for high risk patients. CONCLUSION: Awareness should be minimised by thorough checking of equipment, particularly vaporisers, and frequent application of a structured scanning routine. Awareness may occur during crisis management and aftermath protocols should include patient follow up to detect and manage awareness when it occurs.

Frequency of severe hypoglycemia in patients with type I diabetes with impaired awareness of hypoglycemia.

OBJECTIVE: To determine the frequency of hypoglycemia in patients with type I diabetes and impaired awareness of hypoglycemia by prospective assessment. RESEARCH DESIGN AND METHODS: A prospective study was undertaken for 12 months in 60 patients with type I diabetes: 29 had impaired awareness of hypoglycemia and 31 retained normal awareness of hypoglycemia. The two groups of patients were matched for age, age at onset of diabetes, duration of diabetes, and glycemic control. Episodes of severe hypoglycemia were recorded within 24 h of the event and verified where possible by witnesses. RESULTS: During the 12 months, 19 (66%) of the patients with impaired awareness had one or more episodes of severe hypoglycemia with an overall incidence of 2.8 episodes.patient-1.year-1. By comparison, 8 (26%) of the patients with normal awareness experienced severe hypoglycemia (P < 0.01) with an annual incidence of 0.5 episode.patient-1.year-1 (P < 0.001). Severe hypoglycemia occurred at different times of the day in the two groups: patients with impaired awareness experienced a greater proportion of episodes during the evening (P = 0.03), and patients with normal awareness experienced a greater proportion in the early morning (P = 0.05). An assessment of fear of hypoglycemia revealed that patients with impaired awareness of hypoglycemia worried more about hypoglycemia than did patients with normal awareness (P = 0.008), but did not modify their behavior accordingly. CONCLUSIONS: This prospective evaluation demonstrated that impaired awareness of hypoglycemia predisposes to a sixfold increase in the frequency of severe hypoglycemia, much of which occurred at home during waking hours.

Population awareness and control of hypertension and hypercholesterolemia. The Atherosclerosis Risk in Communities study.

BACKGROUND: A national program for hypertension detection and control was implemented in the 1970s, whereas a similar program for control of hypercholesterolemia has been implemented in recent years. We studied the levels of awareness, treatment, and control of these conditions in US population samples during a 3-year period (1987 to 1989). METHODS: The levels of awareness, treatment (by medication), and adequate control of hypertension (systolic blood pressure, > or = 140 mm Hg; diastolic blood pressure, > or = 90 mm Hg; or antihypertensive medication) and hypercholesterolemia (serum cholesterol level, > or = 6.21 mmol/L [> or = 240 mg/dL], or lipid-lowering medication) were studied among participants in the baseline examination of the Atherosclerosis Risk in Communities Study, including 15,739 individuals aged 45 to 64 years. RESULTS: Eighty-four percent of the hypertensive subjects and 42% of the hypercholesterolemic subjects were aware of their conditions. Overall, 50% of the hypertensive subjects and only 4% of the hypercholesterolemic subjects had their conditions both treated and controlled. Rates of hypertension prevalence, awareness, and control remained stable during the 3-year study period. Hypercholesterolemia prevalence decreased from 30% in 1987 to 25% in 1989; its awareness increased from 31% to 50% during the same period. Hypertensive women were more likely than hypertensive men to be aware and treated, whereas hypercholesterolemia awareness was higher in men than in women. Hypertension awareness was highest in black women, but black hypertensive subjects were less likely than whites to be treated and to have their hypertension controlled. Black hypercholesterolemic subjects were less likely to be either aware or treated. CONCLUSIONS: After the recent implementation of the National Cholesterol Education Program, the levels of awareness, treatment, and control of hypercholesterolemia are improving at a high rate, although they are still substantially lower than those for hypertension. Further improvement is necessary, particularly among certain population groups, such as blacks.

Illness awareness in cancer patients: a conceptual framework and a preliminary classification hypothesis.

The study describes the initial phases of research aimed at developing a methodology for assessing awareness in cancer patients. A first sample of cancer patients (n = 36) was interviewed about their knowledge of the diagnosis and their perception of treatment goals and outcomes. Thirteen domains which refer both to cognitive and emotional areas were identified, and considered as content valid by a panel of six experts. A second sample of patients (n = 54) participated in a semi-structured interview developed to explore awareness by means of the domains identified. Seven patterns of awareness were identified, ranging from 'completely aware patient' to 'completely unaware patient'. Twenty of the 54 patients (37.0%) were completely aware, 19 (35.2%) were partially aware with defence mechanisms and 15 (27.8%) were not aware of their diagnosis. Patients from the National Cancer Institute were more frequently aware (54.3%) compared with the patients interviewed in the community hospitals (5.3%) (p < 0.001). A computerized content analysis allowed the identification of two main groups of patients on the basis of the content of the recorded interviews. This independent classification agreed with the classification of the patients performed by the psychologists, suggesting the validity of the procedure of awareness evaluation proposed in this study.

The role of primary visual cortex (V1) in visual awareness.

In the search for the neural correlate of visual awareness, much controversy exists about the role of primary visual cortex. Here, the neurophysiological data from V1 recordings in awake monkeys are examined in light of two general classes of models of visual awareness. In the first model type, visual awareness is seen as being mediated either by a particular set of areas or pathways, or alternatively by a specific set of neurons. In these models, the role of V1 seems rather limited, as the mere activity of V1 cells seems insufficient to mediate awareness. In the second model type, awareness is hypothesized to be mediated by a global mechanism, i.e. a specific kind of activity not linked to a particular area or cell type. Two separate versions of global models are discussed, synchronous oscillations and spike rate modulations. It is shown that V1 synchrony does not reflect perception but rather the horizontal connections between neurons, indicating that V1 synchrony cannot be a direct neural correlate of conscious percepts. However, the rate of spike discharges of V1 neurons is strongly modulated by perceptual context, and these modulations correlate very well with aspects of perceptual organization, visual awareness, and attention. If these modulations serve as a neural correlate of visual awareness, then V1 contributes to that neural correlate. Whether V1 plays a role in the neural correlate of visual awareness thus strongly depends on the way visual awareness is hypothesized to be implemented in the brain.

Parental awareness of adolescent substance use.

Parental awareness of adolescent substance use was investigated in a high school sample of 985 adolescents and their parents. Only 39% of parents were aware their adolescent used tobacco, only 34% were aware of alcohol use, and only 11% were aware of illicit drug use. There were no variables that differentiated aware from unaware parents for all substances. Greater parental awareness of alcohol and tobacco use occurred with older adolescents. High adolescent ratings of family communication combined with low parental ratings of family communication were also associated with greater parental awareness of alcohol and tobacco use. Better school grades predicted greater awareness of alcohol and illicit drug use. Single parents and blended families were more aware of tobacco and illicit drug use.

How much are patients willing to pay to avoid intraoperative awareness?

STUDY OBJECTIVE: To determine how much patients are willing to pay to avoid intraoperative awareness? DESIGN: Observational study SETTING: University-affiliated metropolitan hospital. PATIENTS: 60 patients who completed a questionnaire (39 F, 21 M). The mean age was 43 years and the median household income range of 45,000-60,000 US dollars. INTERVENTIONS: Patients completed an interactive computer-generated questionnaire on the value of preventing intraoperative awareness and their willingness to pay for a "depth of anesthesia" monitor. Their willingness to pay for the prevention of postoperative pain, nausea and vomiting, postoperative grogginess, and sleepiness was also determined as a means of comparison. MEASUREMENTS AND MAIN RESULTS: Patients were willing to pay (WTP) 34 US dollars, 10 US dollars to 42 US dollars (median, interquartile range) for a monitor that would assist an anesthesia care provider assess the depth of anesthesia in an effort to avoid awareness. This increased to 43 US dollars, 20 US dollars to 77 US dollars (p < 0.0,001) (median, interquartile range), if the insurance company was making the payment and the WTP value only decreased minimally to 33 US dollars if the incidence of awareness was reduced 10-fold. CONCLUSION: The incidence of intraoperative awareness and WTP value for monitoring awareness have a nonlinear relationship (a risk averse utility function), which suggests that patients assign an intrinsic base value for a rare or very rare possibility of an event. Other healthcare economic analyses (such as cost effectiveness) do not take this factor into account and assume a linear value relationship (i.e., if something occurs ten times less frequently, it has ten times less value). IMPLICATION: The median value for patients' WTP for a monitor that might prevent awareness under anesthesia was 34 US dollars given an incidence of 5/1,000 cases. The incidence of awareness and WTP value have a nonlinear relationship suggesting that patients assign an intrinsic base value for the possibility of awareness.

Facilitating phoneme awareness development in 3- and 4-year-old children with speech impairment.

PURPOSE: This study investigated the phonological awareness and early literacy development of 12 children who presented at 3 years of age with moderate or severe speech impairment. The children's response to early intervention that included specific activities to facilitate phoneme awareness and letter knowledge, in addition to improving speech intelligibility, was examined. METHOD: Using a 3-year longitudinal design, the children's development in phonological awareness was monitored and compared to that of a group of 19 children without speech impairment. During the monitoring period from 3 to 5 years of age, the children with speech impairment received, on average, 25.5 intervention sessions. At 6 years of age, the children's performance on phonological awareness, reading, and spelling measures was also compared to that of the 19 children without impairment as well as to a matched control group of children with speech impairment who had not received any specific instruction in phonological awareness. RESULTS: The results indicated that (a) phoneme awareness can be stimulated in children with speech impairment as young as 3 and 4 years of age, (b) facilitating phoneme awareness development can be achieved concurrently with improvement in speech intelligibility, and (c) enhancing phoneme awareness and letter knowledge during the preschool years is associated with successful early reading and spelling experiences for children with speech impairment. CLINICAL IMPLICATIONS: The data provide evidence to support the clinical practice of integrating activities to develop phoneme awareness and letter knowledge into therapy for 3- and 4-year-old children with moderate or severe speech impairment.

Awareness in early-stage Alzheimer's disease: relationship to outcome of cognitive rehabilitation.

Awareness of difficulties may have an important impact on functioning and response to intervention in early-stage Alzheimer's disease (AD). Clinical reports and retrospective studies suggest an association, but this has not previously been tested in a prospective study. Using a new measure of awareness, the Memory Awareness Rating Scale (MARS), which was designed to take account of methodological limitations identified in a review of previous studies, the present study explored the relationship between awareness of difficulties and outcome of a cognitive rehabilitation (CR) intervention in 12 participants with a diagnosis of early-stage Alzheimer's disease. The relationship between awareness and mood, behaviour and executive function was also assessed. The results provide the first demonstration in a prospective study that higher levels of awareness are related to better CR outcomes. Awareness was associated with depression and reported behaviour problems, but not with performance on tests of executive function. These results suggest that variations in level of awareness in early-stage AD are influenced by psychological factors, and that explanatory models need to take these factors into account. Awareness of difficulties may serve as a useful predictor of the likely effectiveness of CR, andthis may assist clinicians in selecting appropriate interventions for individuals with early-stage AD.

Awareness in Gestalt sex therapy.

Awareness is conceived to be selective, curative, a method, a prescription for ideal living, and a ground for human existence. In this paper the following gestalt awareness methods are described: continuum of awareness, awareness questions, biobehavioral feedback, directed awareness, concentration, present-centering, taking responsibilty, and shuttles in awareness. The use of these methods is illustrated in a gestalt therapy dialogue. The application of awareness as concept and method to sensate focus and to the treatment of the prematurely ejaculating male is discussed. Shuttles in awareness and the shared continua of awareness are introduced as promising new methods in the treatment of sexual dysfunction and as enhancing sexual pleasure and communion.

Independence of visual awareness from the scope of attention: an electrophysiological study.

Recent brain imaging studies have revealed that increased neural activity along the ventral visual stream and parietal and frontal areas is associated with visual awareness. In order to study the time-course and temporal aspects of awareness, we examined electrophysiological correlates of conscious vision in two masking experiments. The differences in event-related potentials (ERPs) between unmasked (consciously recognized) and masked (unrecognized) stimuli were considered to be electrophysiological correlates of awareness. Two attentional conditions (global, local) were included to examine the relationship between the scope of attention and awareness. Two ERP-deflections were found to correlate with awareness. First, awareness was associated with a posterior negative amplitude shift 130-320 ms after the stimulus. This effect was present in both attention conditions, suggesting that it emerges independent of the scope of attention. Second, ERPs to unmasked stimuli became more positive as compared with masked stimuli around 400 ms, peaking at parietal sites. This effect was attenuated in the local attention condition, although the participants were aware of the stimuli, suggesting that the late positivity does not directly correlate with visual awareness. The results imply that the earlier negativity is the earliest and most direct correlate of visual awareness.

Cluster analysis of self-awareness levels in adults with traumatic brain injury and relationshipto outcome.

The purpose of this study was to investigate the relationship between self-awareness, emotional distress, motivation, and outcome in adults with severe traumatic brain injury. A sample of 55 patients were selected from 120 consecutive patients with severe traumatic brain injury admitted to the rehabilitation unit of a large metropolitan public hospital. Subjects received multidisciplinary inpatient rehabilitation and different types of outpatient rehabilitation and community-based services according to availability and need. Measures used in the cluster analysis were the Patient Competency Rating Scale, Self-Awareness of Deficits Interview, Head Injury Behavior Scale, Change Assessment Questionnaire, the Beck Depression Inventory, and Beck Anxiety Inventory; outcome measures were the Disability Rating Scale, Community Integration Questionnaire, and Sickness Impact Profile. A three-cluster solution was selected, with groups labeled as high self-awareness (n = 23), low self-awareness (n = 23), and good recovery (n = 8). The high self-awareness cluster had significantly higher levels of self-awareness, motivation, and emotional distress than the low self-awareness cluster but did not differ significantly in outcome. Self-awareness after brain injury is associated with greater motivation to change behavior and higher levels of depression and anxiety; however, it was not clear that this heightened motivation actually led to any improvement in outcome. Rehabilitation timing and approach may need to be tailored to match the individual's level of self-awareness, motivation, and emotional distress.
