A randomized comparison of quadruple and triple therapies for helicobacter pylori eradication: The QUADRATE study.

Background & Aims: Direct comparisons of bismuth and proton pump inhibitor (PPI)-based triple and quadruple therapies for Helicobacter pylori eradication are lacking. To address this, a randomized study was conducted.Methods: Infected dyspeptic patients received pantoprazole 40 mg, amoxicillin 1000 mg, and clarithromycin 500 mg, all twice daily, for 7 days (PAC7); or pantoprazole 40 mg twice daily, bismuth subcitrate 108 mg, and tetracycline 500 mg, both 4 times daily, and metronidazole 200 mg 3 times daily and 400 mg at night for 7 days (PBTM7); bismuth subcitrate 108 mg and tetracycline 500 mg, both 4 times daily, and metronidazole 200 mg 3 times daily and 400 mg at night for 14 days (BTM14). Outcome was assessed with ¹³C-urea breath test.Results: Eradication rates (intention to treat [n = 405]/per protocol [n = 320]) were similar for PAC7 (78%/82%) and PBTM7 (82%/88%); the latter significantly superior to BTM14 (69%/74%; P < 0.01). Pretreatment metronidazole resistance (MR) was 53% and clarithromycin resistance was 8%. Eradication rates for primary metronidazole sensitive/resistant isolates were 74%/87% with PAC7 and 80%/81% for PBTM7, compared with 76%/55% (P < 0.02) for BTM14. Noncompliance was greater with BTM14 (15%; P < 0.001) than PAC7 (3%) or PBTM7 (6%). Moderate-severe adverse events were more common with BTM14 (45%; P < 0.001), than PAC7 (23%) or PBTM7 (25%) with more discontinuations (9%, 2%, 3%, respectively).Conclusions: One-week PPI triple therapy is well tolerated and effective. The addition of PPI to bismuth triple therapy allows reduction of treatment duration with improved efficacy and tolerability, despite a high rate of MR. Quadruple therapy appears to overcome pretreatment MR in most cases. Two-week bismuth triple therapy is significantly inferior to quadruple therapy and less well tolerated than both 1-week therapies.

Qualitative analysis of the care of children in hospital in four countries : part 2

As part of a large study of the care of children in Australian, British, Indonesian, and Thai hospitals, qualitative methods were used to examine differences influenced by culture. Two groups were surveyed: parents of hospitalized children, and staff caring for them. Vignettes were used to invoke discussion, and content analysis was used to examine the data. Subjects were interviewed singly, or in focus groups. These interviews were audiotaped and transcribed for analysis. This article is the second of a two-part series, and includes results of the staff's interviews and discussion. The parents' results and discussion were published in Part 1 (Shields [amp ] King, 2001). Staff in all the countries considered communication with parents to be an important part of care of the hospitalized child, and this was consistent with the parents' responses. Staff were mindful of safe practices, though more so in Australia and Britain than Indonesia and Thailand. Cost of treatment for the parents was an important consideration for staff in Indonesia and Thailand when they were planning care for the child. Cultural constructions were more likely to be considered by the Australian and British staff than the Indonesian and Thai staff, and this may have been influenced by the prevailing culture of medical dominance in those countries.

Blood-nourishing and hard-softening capsule costs less in the management of osteoarthriticknee pain : A randomized controlled trial

The blood-nourishing and hard-softening (BNHS) capsule is a traditional Chinese formula used in the symptomatic treatment of inflammation and pain. We conducted this randomized controlled trial to compare the efficacy of BNHS with other commonly prescribed drugs. We recruited 120 patients from two teaching hospitals; 30 patients in each hospital were randomly assigned to receive BNHS. In one hospital, the 30 controls were given another traditional Chinese drug; whereas a Western medicine (chondroprotection drug/Viartril-s) was used as the control in the other hospital. Intervention was carried out over a period of 4 weeks. Primary outcome measures included self-reported pain level, and changes in stiffness and functional ability as measured by the Western Ontario McMaster Universities Osteoarthritis (WOMAC) index. Mixed models were used for statistical analysis. Substantial improvements in disease-specific symptoms were observed, after 4 weeks of treatment, in patients taking BNHS capsules. As assessed by the WOMAC index, pain level of the BNHS group decreased by 57% [95% confidence interval (CI) = 50, 63], stiffness by 63% (95% CI = 55, 71) and functional ability increased by 56% (95% CI = 50, 63). No significant differences were found in any of the outcome measures between the BNHS group and either of the comparison groups. No severe adverse effects were reported. However, this study lacked a placebo group; therefore, we conclude that BNHS appears to be as effective as commonly prescribed medicines for the relief of pain and dysfunction in knee osteoarthritis patients, but costs a lot less than other Western and herbal drugs in the study.

Efficacy of neuromuscular electrical stimulation in improving ankle kinetics during walking in children with cerebral palsy

Neuromuscular electrical stimulation (NMES) applied to the triceps surae muscle is claimed to be effective in improving gait in children with cerebral palsy. The main aim of this study was to determine the effect of NMES on the triceps surae muscle in improving the gait and function of children with cerebral palsy. Twelve children with spastic diplegia or hemiplegia were recruited and randomly assigned to the two experimental groups. The period of the study was 8 weeks (2-4-2 week design). The initial 2 weeks was the control period, in which usual treatment was given to both groups of patients with a pre- and post-treatment assessment. The middle 4 weeks was the experimental period, in which the Treadmill+NMES group received NMES plus treadmill walking training and the Treadmill group underwent treadmill walking training only. Assessment was performed at 2-week intervals. The final 2 weeks was the carryover period, in which treatment to be tested was stopped and reassessment performed again at the end of week 8. An additional treatment and post-treatment assessment were given at weeks 2, 4 and 6 to test for the immediate effect of treatment. Altogether, eight repeated measures with three-dimensional gait analysis and five clinical measurements using the gross motor function measure (GMFM) were performed. Kinetic changes in ankle moment quotient (AMQ) and ankle power quotient (APQ) were not significant either immediately or cumulatively in both groups. Improvement in trend was observed in both groups immediately but not cumulatively. Using the GMFM, functional changes were detected in standing (GMST, p < 0.001) and in walking (GMWK, p = 0.003) using a 'time' comparison. Significant interaction was also detected in GMWK using 'treatment by time' (p = 0.035). The difference between the two groups was not significant on 'treatment' comparison of both GMST and GMWK. Both groups showed improvement in GMST and GMWK cumulatively but there was no difference between the two groups. The effects in both groups could be carried over to 2 weeks after interventions stopped. Both the Treadmill+NMES and Treadmill groups showed improvement in functional outcomes. The trend in the changes of the GMFM score suggested that improvements were greater in the Treadmill+NMES group. There was also a trend showing some immediate improvement in AMQ and APQ.

Quality-of-life measurement in patients undergoing radiation therapy for head and neck cancer: a Hong Kong experience

The aims of this study are (1) to establish a reliable and valid quality-of-life (QOL) questionnaire for Chinese patients with head and neck (H&N) cancer who are treated with radiation therapy and (2) to evaluate the impact of the immediate side effects of treatment on the QOL of these patients. The 39-item "Quality of Life Radiation Therapy Instrument with Head and Neck Companion Module" (QOL-RTI/H&N) was translated into Chinese. In the reliability evaluation phase (study module 1), the questionnaire was administered twice to 56 H&N cancer patients, 7 days apart, during the second and third week of radiation therapy. In the validity evaluation phase (study module 2), 138 patients completed the QOL-RTI/H&N before starting and at the end of radiation therapy. Sixty-nine of these 138 patients also completed the QOL-RTI/H&N during the second week of their radiation therapy, at the same time as completing the Functional Assessment of Cancer Therapy-Head and Neck (FACT-H&N) questionnaire. Cronbach alpha coefficients were 0.88 for the general-tool QOL-RTI and 0.90 for the H&N subscale. Test-retest reliability was satisfactory with intraclass correlation coefficients of 0.89 for the general-tool QOL-RTI and 0.75 for the H&N subscale. The instrument can discriminate between patients with stage I or II disease and those with stage III or IV disease (P < .05). Concurrent validity was established by the good agreement with the FACT-H&N (r = 0.86, P < .001). A highly significant deterioration was in the QOL from the baseline to the end of treatment (mean difference for general tool = 1.95, P < .001; mean difference for H&N subscale = 4.85, P < .001). The Chinese QOL-RTI/H&N is a reliable and valid tool for determining the QOL in H&N cancer patients receiving radiation therapy. The immediate side effects of treatment had a significantly negative impact on the patients' QOL. The impact was relatively large for the functional and treatment-site aspects.

A theory of injustice: the flip side of the relocation coin in Australia

Problems attached to relocation cases in Australia because of geographical and cultural reasons - the best interests of the child principle inherently promotes injustice in relocation cases - operation of Part VII of the Family Law Act in the context of relocation cases - assessment of the best interests of the child principle in Australian relocation cases - responsibility of contact parents - reforming Australian law to promote an equality of interests.

Effects of atmospheric pressure plasma on dye uptake by the surface of wool

A woven pure wool fabric has been exposed to atmospheric pressure plasma for 30 seconds using a pilot-scale. commercial machine. X-ray photoelectron spectral data revealed large increases in oxygen and nitrogen. and a large reduction in carbon. on the surfaces of the plasma-treated fibres. A CIN ratio of 3.55 for plasma-treated wool was consistent with removal of the covalently-bound fatty acids from the surface of the cuticle cells. resulting in exposure of the proteinaceous epicuticle. Dye staining experiments revealed that the back of the fabric had received the same, uniform level of treatment as the face, despite the fact that only the face had been directly exposed to the plasma. Dyes (1 % oww) were applied to fabric at 50°C (liquor ratio =40: 1) and pH values from 3 to 6. The relatively low temperature of 50°C was selected in order to accentuate the effects of plasma on the rate of dye uptake. Under these conditions, dye was adsOibed onto the fibre surfaces, with very little penetration into the fibres. Effects of the plasma treatment on the rate of dyes adsorption were dyespecific. No significant effects of plasma on the rate of dye uptake were observed with relatively hydrophobic dyes, but hydrophilic dyes were adsorbed more rapidly by the plasmatreated fabric. It would appear that for more hydrophobic dyes, hydrophobic effects are more important for the adsorption of dyes by the plasma-treated fibres, even though these fibres were quite hydrophilic. On the other hand. it is concluded that for more hydrophilic dyes, electrostatic effects are more important for adsorption by the plasma-treated fibre.

Internet-based psychological and oral medical treatment compared to psychological treatment alone for ED

Introduction. Sexual function through pregnancy and the postpartum period is an important aspect of quality of life.
Despite this, prospective studies are limited, and the impact of body image on sexual function has not been explored.
Aims. The current study reports on a pilot study that evaluated the effectiveness of a combined Internet-based
psychological treatment program and oral medication compared to an Internet-based psychological program.
Methods. Twelve men with ED participated in the study.
Main Outcome Measures. Assessments were made pre and postintervention on ED, relationship satisfaction, sexual
satisfaction, self-esteem, and quality of life.
Results. Multivariate analyses of variance demonstrated that both treatment conditions showed improvements from
pretest to posttest in sexual functioning, relationships, and personal well-being.
Conclusions. This study indicates the importance of targeting psychological and relationship variables in the
treatment of ED. Further research with larger numbers of participants is necessary for a more rigorous evaluation
of treatment programs that combine psychological and medication interventions for ED.

Defining dual diagnosis : a qualitative study of the views of health care workers

Background: 'Dual diagnosis' is the term of choice in many countries to describe clients with co-occurring mental health and alcohol and other drug (AOD) issues. However, it is not known if its meaning is consistently represented within and across health care services. This uncertainty has significant implications for referral, consultation and research.
Aim: To obtain information about the way that different health care professionals understand the term 'dual diagnosis'.
Method: Twenty-nine health care workers across five service types (medical, mental health, AOD, dual diagnosis and community health) in Victoria, Australia were interviewed about their understanding of the term 'dual diagnosis'.
Results: The findings indicated that service providers working in AOD and Mental Health had a shared general understanding of what was meant by 'dual diagnosis', despite uncertainties about more specific inclusion criteria. In contrast, medical and community health staff lacked a similar shared understanding, and were more likely to recommend change, but offered no consensus on alternatives.
Conclusion: The results indicate that while the term 'dual diagnosis' has value in efficiently directing attention to the complexity of treatment issues, health practitioners cannot assume it will convey the intended meaning outside mental health or AOD services. Clear articulation of the intended definition may be a necessary requirement in wider health care communication.

Where the home in valley meets the damp dirty prison : a human rights perspective on therapeutic jurisprudence and the rule of forensic psychologists in correctional settings

The roles of forensic psychologists in coerced environments such as corrections include that of treatment provider (for the offender) and that of organizational consultant (for the community). This dual role raises ethical issues between offender rights and community rights; an imbalance results in the violation of human rights. A timely reminder of a slippery ethical slope that can arise is the failure of the American Psychological Association to manage this balance regarding interrogation and torture of detainees under the Bush administration. To establish a “bright-line position” regarding ethical practice, forensic psychologists need to be cognizant of international human rights law. In this endeavor, international covenants and a universal ethical code ought to guide practice, although seemingly unresolveable conflicts between the law and ethics codes may arise. A solution to this problem is to devise an ethical framework that is based on enforceable universally shared human values regarding dignity and rights. To this end, the legal theory of therapeutic jurisprudence can assist psychologists to understand the law, the legal system, and their role in applying the law therapeutically to support offender dignity, freedom, and well-being. In this way, a moral stance is taken and the forensic role of treatment provider and/or organizational consultant is not expected to trump the prescriptions and the proscriptions of the law.

The effect of estrogen on Akt signalling and protein synthesis in C2C12 mouse skeletal myotubes

The maintenance of skeletal muscle mass is a critical component of health in both chronic wasting diseases and aging. A considerable amount of progress has been made in the understanding of the signalling pathways that mediate skeletal muscle hypertrophy and atrophy. Akt is seen as a key molecular protein involved in the maintenance of skeletal muscle mass as it has the dual ability to positively influence protein syntheses and negatively regulate protein degradation in its active state (Glass, 2003). Potential mechanisms which may assist with maintaining skeletal muscle mass are the estrogen hormones. Estrogens increase the proliferation of mouse and rat myoblasts and can also attenuate immobilization-induced skeletal muscle atrophy in rats in vivo (Kahlert et al., 1997). No studies have investigated the effect of estrogens on the activation of skeletal muscle hypertrophy and atrophy signalling pathways. Estrogens may contribute to maintaining skeletal muscle mass via their activation of the Akt signalling pathways. Therefore, the aims of the present study were to determine if treatment of C2C12 myotubes with either 17β-estrodiol or estrone increases the activity of Akt and its downstream anabolic signalling proteins, GSK, p70s6k and 4E-BP1 and decreases its catabolic stimulating targets, FOXO, atrogin-1 and MuRF-1. A secondary aim was to determine if this was associated with an increased rate of protein synthesis.

C2C12 myotubes were incubated at 37°C in serum free DMEM without phenol red containing 10 000 units/ml penicillin, 10 000 μg/ml streptomycin, and 250μg/ml amphotericin B for 24h. Myotubes were then stimulated with 17-β estradiol (10nM) for 24h. Phosphorylated and total proteins for Akt, p70S6k, GSK3β, 4E-BP1, FOXO and atrogin-1 were measured using western blotting techniques. Atrogin-1 and MuRF1 mRNA levels were measured using real time-PCR. Protein synthesis rates were measured by incorporation of [3H]-tyrosine into the myotubes during the last hour of treatment.

Compared to control myotubes, treatment with 17β-estradiol increased the ratio of phosphorylated to total protein contents for Akt, GSK-3β and P70s6k by, 1.62, 1.53 and 2.2 fold, respectively (n=6 per group; p < 0.05). There was, however, no difference in the ratios of phosphorylated to total 4E-BP1 or Foxo3a or Atrogin-1 and MuRF1 mRNA. Protein synthesis rates remained unchanged.

This study demonstrates that in C2C12 mouse myotubes, 17β-estradiol treatment increases the phosphorylation of the hypertrophy signalling protein, Akt, and its downstream hypertrophy signalling targets, GSK-3β and P70s6k; no associated changes in protein synthesis were observed. Future studies should investigate the ability of 17β-estradiol to activate these proteins in a model of myotube catabolism and to determine if protein degradation is attenuated.

Individual, social and environmental determinants of participation in physical activity for prostate cancer survivors

Participation in physical activity helps prostate cancer survivors to cope with the side effects of treatment, enhances quality of life and decreases the risks of many of the comorbidities to which survivors are highly susceptible. Prostate cancer survivors, however, are less likely than other cancer survivors (e.g., breast and colorectal) to increase physical activity after diagnosis. Interventions have been only modestly successful at increasing participation in physical activity for prostate cancers survivors and more research is needed to increase our understanding of the determinants of physical activity for this group. Using a social ecological framework, this qualitative research sought to examine the individual, social and environmental determinants of participation in physical activity for prostate cancer survivors. In-depth interviews were conducted with 20 survivors of prostate cancer aged between 35 and 75 years. Participants were drawn from a public and a private health service and from a range of treatment types. We are currently collecting data for this study and preliminary themes will be discussed at the conference (abstract will be updated once findings are known).

The process of change in offender rehabilitation programmes

Whilst the overall effectiveness of offender rehabilitation programmes in reducing recidivism is now well established, there has been less discussion of the reasons why rehabilitation programmes may be unsuccessful for some offenders. In this paper we suggest that models of change developed in counselling and psychotherapy may have utility in explaining how offender rehabilitation programmes bring about change, and argue that the dominance of cognitive-behavioural treatments in the rehabilitation field means that those offenders who have particularly low levels of problem awareness may be at increased risk of treatment failure. Understanding more about the mechanisms by which programmes help offenders to desist from offending is likely to lead to the development of more responsive and, ultimately, more effective programmes. Some suggestions for those involved in the delivery of offender rehabilitation programmes include: being mindful of the sequence of components of programmes, the development of preparation (or readiness) programmes and offering a broad suite of programmes to cater for different stages of problem awareness and assimilation among offenders.

Assessing treatment readiness in violent offenders

Although violent offenders are widely considered to be difficult to engage in therapeutic change, few methods of assessing treatment readiness currently exist. In this article the validation of a brief self-report measure designed to assess treatment readiness in offenders who have been referred to violent offender treatment programs is described. The measure, which is an adaptation of a general measure of treatment readiness developed in a previous work, displayed acceptable levels of convergent and discriminant validity and was able to successfully predict treatment engagement in violent offender treatment. These results suggest that the measure has utility in the assessment of treatment readiness in violent offenders.

Detection of depression in patients with low vision

Purpose. Depression is common in people with vision impairment and further reduces levels of functioning independent of vision loss. However, depression most often remains undetected and untreated this group. Eye health  professionals (EHPs) (ophthalmic nurses, ophthalmologists, optometrists, and orthoptists) and rehabilitation workers (RWs) may be able to play a role in detecting depression. This study aimed to identify current practice and investigate factors associated with depression management strategies.
Methods. A self-administered cross-sectional survey of EHPs and RWs assessed current practice including confidence in working with depressed people with vision impairment; barriers to recognition, assessment, and management of depression; beliefs about the consequences, duration, and efficacy of treatment for depression in individuals with vision impariment.
Results. Ninety-four participants aged 23 to 69 years took part. Thirty-seven participants (39.8%) stated that they attempted to identify depression as part of patient management, with RWs significantly more likely to do so (n = 17, 60.7%) than EHPs (n = 20, 30.8%; p = 0.007). Intention to identify depression was not associated with sociodemographic factors, professional experience in eye care services, or the length and number of patient consultations, but a significant relationship was found for confidence, barriers, and beliefs about depression (p < 0.05). No consistent depression management strategy emerged and a range of barriers were highlighted.
Conclusions. Training programs are needed to provide EHPs and RWs with the skills and resources to address depression in people with vision loss under their care and to support the development of procedures by which concerns about depression can be identified objectively, documented, and included as part of a referral to appropriate services.
