Asylum seeker’s ‘brain death’ shows failure of care and of democracy

The news that Hamid Kehazaei, a 24-year-old Iranian asylum seeker detained on Manus Island, has been diagnosed as brain dead following his transfer to the Mater Hospital in Brisbane is a tragedy. That it is a tragedy for this young man and his family is unquestionable – but the extent of this tragedy may be much more pervasive than we realise. If the emerging details of his case are correct, Kehazaei developed septicaemia as a complication of cellulitis (skin and soft-tissue infection) arising from a cut in his foot. This, in itself, is disturbing. Severe infection can result in brain death – either from infection of the brain itself (meningitis, encephalitis or brain abscess), or from brain injury due to a lack of oxygen resulting from cardiac arrest (as appears to be the case here), or from reduced blood supply to the brain. Yet it is very uncommon, especially in a young, previously healthy man. Such a case could occur in Australia and has been described in 2012 in young Indigenous adults in Central Australia. Nevertheless, severe sepsis resulting from a foot infection is preventable. And a case like this occurring in an Australian national would raise serious questions about the appropriateness of the antibiotics used and the timeliness of care. Most cases of brain death result from traumatic brain injury, stroke or lack of oxygen to the brain following asphyxia, near-drowning, or prolonged cardiopulmonary resuscitation. What happened to Hamid Kehazaei raises concerns about the adequacy of care provided to him during initial treatment, including wound care and antibiotics, and how soon he was transferred to expert medical care, first to Port Moresby and subsequently to Brisbane. If this young man became ill and had his brain die while seeking asylum in Australia and while in our care, then we must examine the details of his case and ask ourselves not only whether it was preventable but whether our policies and processes actually contributed to his death

Participant music listening behaviours in interactive multimedia music instruction

While emerging technologies such as interactive multimedia are increasingly being employed in computerised music instruction, understanding of participant music listening behaviours in interactive multimedia music instruction is currently very limited. With the aim of elucidating music listening behaviour, the central concern of this work is to identify and explain participant interactions with the audio components of interactive multimedia music instruction. The investigation employs a novel documentation procedure, which extends the application of digital audio recording technology, to provide a finely calibrated analysis of the audio activity of a sample of 20 undergraduate music education majors during individual sessions with two commercially-available interactive multimedia music instruction programs. Graphically-based Sound Activity Profiles, which the researcher developed specifically for the current investigation, characterise and summarise participant interactions with audio components, while an analysis of questionnaire responses and follow-up interview transcripts provides supplementary information that further explains participants' music listening behaviours. The results of the investigation show that music listening behaviours during the study sessions were highly variable. While extensive participant interaction with music examples occasionally reflected attentive music listening behaviours, many study sessions were characterised by brief, fragmentary music excerpts and lengthy periods of silence. Participants spent as little as five percent of their session time listening to music and as much as 88 percent of the session time in silence. A substantial number of the study cohort frequently interrupted the music examples they had activated. Participants' perceptions of the extent of their interaction with music examples were frequently inaccurate, as subjects often substantially overestimated the amount of session time they had spent listening to music. The study findings suggest that many interactive multimedia music instruction participants would benefit from interventions that elicit more extensive and prolonged interaction with music examples. Accordingly, recommendations include a call for research to develop and test software designs that incorporate automated monitoring of session audio activity so that dynamic on-screen information about music listening behaviour can be provided to interactive multimedia music instruction participants. Such information may encourage participants to modify inappropriate music listening behaviours

Shortened time interval between colorectal cancer diagnosis and risk testing for hereditary colorectal cancer is not related to higher psychological distress

Current diagnostic practices have shortened the interval between colorectal cancer (CRC) diagnosis and genetic analysis for Lynch syndrome by MSI-testing. We studied the relation of time between MSI-testing since CRC diagnosis (MSI–CRC interval) and psychological distress. We performed a cross-sectional study in 89 patients who had previously been treated for CRC. Data were collected during MSI-testing after genetic counseling. Psychological distress was measured with the IES, the SCL-90 and the POMS; social issues with the ISS, ISB and the ODHCF. The median time of MSI–CRC interval was 24 months (range 0–332), with 23% of the patients diagnosed less than 12 months and 42% more than 36 months prior to MSI-testing. In 34% of the patients cancer specific distress was high (IES scores >26). Mean psychopathology (SCL-90) scores were low, mean mood states (POMS) scores were moderate. Interval MSI–CRC was not related to psychological distress. High cancer specific distress was reported by 24% of patients diagnosed with CRC less than 12 months ago versus 39 and 35% by those diagnosed between 12 and 36 months and more than 36 months ago respectively. Distress was positively related to female gender (P = 0.04), religiousness (P = 0.01), low social support (P = 0.02) and difficulties with family communication (P < 0.001). Shortened time interval between CRC diagnosis and MSI-testing is not associated with higher psychological distress. Females, religious persons, those having low social support and those reporting difficulties communicating hereditary colorectal cancer with relatives are at higher risk for psychological distress

Prognostic Factors for Distress After Genetic Testing for Hereditary Cancer

The psychological impact of an unfavorable genetic test result for counselees at risk for hereditary cancer seems to be limited: only 10-20 % of counselees have psychological problems after testing positive for a known familial mutation. The objective of this study was to find prognostic factors that can predict which counselees are most likely to develop psychological problems after presymptomatic genetic testing. Counselees with a 50 % risk of BRCA1/2 or Lynch syndrome completed questionnaires at three time-points: after receiving a written invitation for a genetic counseling intake (T1), 2-3 days after receiving their DNA test result (T2), and 4-6 weeks later (T3). The psychological impact of the genetic test result was examined shortly and 4-6 weeks after learning their test result. Subsequently, the influence of various potentially prognostic factors on psychological impact were examined in the whole group. Data from 165 counselees were analyzed. Counselees with an unfavorable outcome did not have more emotional distress, but showed significantly more cancer worries 4-6 weeks after learning their test result. Prognostic factors for cancer worries after genetic testing were pre-existing cancer worries, being single, a high risk perception of getting cancer, and an unfavorable test result. Emotional distress was best predicted by pre-existing cancer worries and pre-existing emotional distress. The psychological impact of an unfavorable genetic test result appears considerable if it is measured as "worries about cancer." Genetic counselors should provide additional guidance to counselees with many cancer worries, emotional distress, a high risk perception or a weak social network

Time-restricted feeding improves adaptation to chronically alternating light-dark cycles

Disturbance of the circadian clock has been associated with increased risk of cardio-metabolic disorders. Previous studies showed that optimal timing of food intake can improve metabolic health. We hypothesized that time-restricted feeding could be a strategy to minimize long term adverse metabolic health effects of shift work and jetlag. In this study, we exposed female FVB mice to weekly alternating light-dark cycles (i.e. 12 h shifts) combined with ad libitum feeding, dark phase feeding or feeding at a fixed clock time, in the original dark phase. In contrast to our expectations, long-term disturbance of the circadian clock had only modest effects on metabolic parameters. Mice fed at a fixed time showed a delayed adaptation compared to ad libitum fed animals, in terms of the similarity in 24 h rhythm of core body temperature, in weeks when food was only available in the light phase. This was accompanied by increased plasma triglyceride levels and decreased energy expenditure, indicating a less favorable metabolic state. On the other hand, dark phase feeding accelerated adaptation of core body temperature and activity rhythms, however, did not improve the metabolic state of animals compared to ad libitum feeding. Taken together, restricting food intake to the active dark phase enhanced adaptation to shifts in the light-dark schedule, without significantly affecting metabolic parameters

BRCA1/2 mutation testing in breast cancer patients: a prospective study of the long-term psychological impact of approach during adjuvant radiotherapy

This study assessed psychological distress during the first year after diagnosis in breast cancer patients approached for genetic counseling at the start of adjuvant radiotherapy and identified those vulnerable to long-term high distress. Of the approached patients some chose to receive a DNA test result (n = 58), some were approached but did not fulfill criteria for referral (n = 118) and some declined counseling and/or testing (n = 44). The comparative group consisted of patients not eligible for genetic counseling (n = 182) and was therefore not approached. Patients actively approached for genetic counseling showed no more long-term distress than patients not eligible for such counseling. There were no differences between the subgroups of approached patients. Predictors for long-term high distress or an increase in distress over time were pre-existing high distress and a low quality of life, having children, and having no family members with breast cancer. It is concluded that breast cancer patients can be systematically screened and approached for genetic counseling during adjuvant radiotherapy without imposing extra psychological burden. Patients vulnerable to long-term high distress already displayed high distress shortly after diagnosis with no influence of their medical treatment on their level of distress at long-term

Psychological distress in newly diagnosed colorectal cancer patients following microsatellite instability testing for Lynch syndrome on the pathologist’s initiative

According to the Dutch Guideline on Hereditary Colorectal Cancer published in 2008, patients with recently diagnosed colorectal cancer (CRC) should undergo microsatellite instability (MSI) testing by a pathologist immediately after tumour resection if they are younger than 50 years, or if a second CRC has been diagnosed before the age of 70 years, owing to the high risk of Lynch syndrome (MIPA). The aim of the present MIPAPS study was to investigate general distress and cancer-specific distress following MSI testing. From March 2007 to September 2009, 400 patients who had been tested for MSI after newly diagnosed CRC were recruited from 30 Dutch hospitals. Levels of general distress (SCL-90) and cancer-specific distress (IES) were assessed immediately after MSI result disclosure (T1) and 6 months later (T2). Response rates were 23/77 (30%) in the MSI-positive patients and 58/323 (18%) in the MSI-negative patients. Levels of general distress and cancer-specific distress were moderate. In the MSI-positive group, 27% of the patients had high general distress at T1 versus 18% at T2 (p = 0.5), whereas in the MSI-negative group, these percentage were 14 and 18% (p = 0.6), respectively. At T1 and T2, cancer-specific distress rates in the MSI-positive group and MSI-negative group were 39 versus 27% (p = 0.3) and 38 versus 36% (p = 1.0), respectively. High levels of general distress were correlated with female gender, low social support and high perceived cancer risk. Moderate levels of distress were observed after MSI testing, similar to those found in other patients diagnosed with CRC. Immediately after result disclosure, high cancer-specific distress was observed in 40% of the MSI-positive patients
