ABSTRACT

Aims Burkitt Lymphoma (BL) accounts for approximately 40% of childhood non-Hodgkin Lymphoma (NHL) in the developed world. Survival rates have improved dramatically in recent years, a success attributed to better use of poly-chemotherapy and targeted immunotherapy. Nevertheless, relapse is unpredictable and carries a dismal prognosis. We report on event-free survival (EFS) and overall survival (OS) rates in the Republic of Ireland (ROI) during 2000-2017, and evaluate novel predictors of outcome. Methods Data was collected by retrospective review of patient medical records. Results Thirty-three patients were identified (twenty-five [76%] males, eight [24%] females), fourteen [42%] having stage III disease at presentation. Six [18%] had stage IV disease. Five [15%] had refractory disease; one salvaged with allogeneic stem cell transplantation. Of the four [12%] who died; two [50%] had weights >99th centile, one [25%] >90th centile. One died during induction from refractory lactic acidosis, one from early relapse. Discussion EFS and OS was 85% and 89% respectively; in keeping with the best international standards. Obesity appears to be a poor predictor of outcome in our cohort.

ABSTRACT

The concept of self-healing asphalt mixtures by bitumen temperature increase has been used by researchers to create an asphalt mixture with crack-healing properties by microwave or induction heating. Metals, normally steel wool fibers (SWF), are added to asphalt mixtures prepared with virgin materials to absorb and conduct thermal energy. Metal shavings, a waste material from the metal industry, could be used to replace SWF. In addition, reclaimed asphalt pavement (RAP) could be added to these mixtures to make a more sustainable road material. This research aimed to evaluate the effect of adding metal shavings and RAP on the properties of asphalt mixtures with crack-healing capabilities by microwave heating. The research indicates that metal shavings have an irregular shape with widths larger than typical SWF used with asphalt self-healing purposes. The general effect of adding metal shavings was an improvement in the crack-healing of asphalt mixtures, while adding RAP to mixtures with metal shavings reduced the healing. The average surface temperature of the asphalt samples after microwave heating was higher than temperatures obtained by induction heating, indicating that shavings are more efficient when mixtures are heated by microwave radiation. CT scan analysis showed that shavings uniformly distribute in the mixture, and the addition of metal shavings increases the air voids. Overall, it is concluded that asphalt mixtures with RAP and waste metal shavings have the potential of being crack-healed by microwave heating.

ABSTRACT

Understanding the effects of population diversity on cancer-related experiences is a priority in oncology care. Previous research demonstrates inequalities arising from variation in age, gender and ethnicity. Inequalities and sexual orientation remain underexplored. Here, we report, for the first time in the UK, a quantitative secondary analysis of the 2013 UK National Cancer Patient Experience Survey which contains 70 questions on specific aspects of care, and six on overall care experiences. 68,737 individuals responded, of whom 0.8% identified as lesbian, gay or bisexual. Controlling for age, gender and concurrent mental health comorbidity, logistic regression models applying post-estimate probability Wald tests explored response differences between heterosexual, bisexual and lesbian/gay respondents. Significant differences were found for 16 questions relating to: (1) a lack of patient-centred care and involvement in decision-making, (2) a need for health professional training and revision of information resources to negate the effects of heteronormativity and (3) evidence of substantial social isolation through cancer. These findings suggest a pattern of inequality, with less positive cancer experiences reported by lesbian, gay and (especially) bisexual respondents. Poor patient-professional communication and heteronormativity in the healthcare setting potentially explain many of the differences found. Social isolation is problematic for this group and warrants further exploration.

ABSTRACT

BACKGROUND: Post-transplant lymphoproliferative disease (PTLD) is a serious complication of both solid organ and haematopoietic stem cell transplantation in children. Its incidence has increased over the last decade as a result of more potent immunosuppressive regimens. Many treatments have been explored however optimal therapy remains controversial. AIMS: We report on the diagnosis, treatment and outcome of ten patients who were diagnosed with PTLD in Our Lady's Hospital for Sick Children in Dublin between 2004 and 2015 inclusive. METHODS: Data were collected by retrospective review of patient medical records. RESULTS: 9 out of ten of our patients are alive and disease free following treatment for PTLD with rituximab alone or in combination with chemotherapy. CONCLUSION: The outcome of paediatric patients treated for PTLD at our institution is at least comparable to published international series and supports the use of rituximab ± low dose chemotherapy in the treatment of this malignancy.

ABSTRACT

Cancer is an illness affecting patients' physical and psychosocial well-being: high numbers report problematic levels of distress at many points through diagnosis, treatment and survivorship. Conclusive evidence for the long-term benefits of psychological interventions is lacking and this may be because (1) they employ a too limited scope of underlying therapeutic model; or (2) that they are too focused on improving psychopathological outcomes. Acceptance and Commitment Therapy (ACT) may add components not emphasised elsewhere and may provide a more suitable model of adjustment and coping. Following a comprehensive literature search a theoretical and conceptual discussion of the potential for ACT-based oncology interventions is presented. Only a small number of studies have purposively studied the application of ACT within the cancer setting, but this nonetheless presents useful pilot data. The data demonstrate potential clinical- and cost-effectiveness for a range of patients, including those with psychological comorbidity. Within the context of wider cancer adjustment, ACT offers an intervention framework to appropriately build upon the strong empirical base already established for Mindfulness within this specific patient population. The evidence available suggests that the underlying framework of ACT offers an intervention model that is potentially more suited to the individualistic nature of cancer adjustment.

ABSTRACT

BACKGROUND: Down syndrome (DS), the most common syndromic chromosomal abnormality is associated with a unique susceptibility to develop both acute myeloid (ML) and lymphoblastic leukaemia (ALL). These leukaemias differ from the non-DS-related types of leukaemia and are thought to be distinct biological entities. AIMS: To perform a retrospective review of our experience of treating DS-related leukaemia at Our Lady's Children's Hospital. METHODS: Data were extracted from a database established in 2000 to prospectively gather data on DS-associated leukaemias and their outcomes following polychemotherapy. Kaplan-Meier survival curves were constructed. RESULTS: Nineteen patients with DS-ML were treated and 19 with DS-ALL. Sixteen (84%) patients with DS-ML are alive and in complete remission with a median follow-up of 7 years. All deaths in this cohort were due to treatment-related mortality (TRM). Of the DS-ALL patients, 12 (63%) remain alive with a median follow-up of 3.6 years. TRM accounted for five of the six deaths. One death was due to leukaemic relapse. CONCLUSION: High cure rates are seen in DS-ML using contemporary polychemotherapy protocols, however, there is significant TRM in this cohort. DS-ALL does not have the same high cure rate as non-DS-ALL (>90%) and again this is mainly due to an excess of TRM.

ABSTRACT

PURPOSE: This study explores the experiences and sense of burden of family carers of survivors of malignant middle cerebral artery infarctions who had undergone decompressive hemicraniectomy. To date, there have been no studies examining carer outcomes among this unique population. This study, taken alongside an already published study of survivor outcomes, provides a more holistic picture with regard to sequelae within the sample. METHOD: Six family carers completed the Sense of Competence Questionnaire and the Hospital Anxiety and Depression Scale. These results were compared with existing normative data. Carers also consented to a semi-structured interview. Interview data were examined using thematic content analysis. Consistent with the mixed methods design, quantitative and qualitative findings were integrated for further analysis. RESULTS: While carers experienced many losses, their overall sense of burden was not outside 'Average' limits, nor did they experience clinically significant symptoms of depression. All carers identified methods of coping with the demands of caregiving. These included intrapersonal, interpersonal and practical strategies. All carers apart from one were able to identify areas of post-traumatic growth. CONCLUSION: Carers will benefit from information, support and care. In addition, problem solving skills are essential in managing the myriad difficulties that arise in the aftermath of stroke.

ABSTRACT

BACKGROUND: Acute lymphoblastic leukaemia (ALL), the commonest childhood malignancy has seen remarkable progress since the 1960s with cure rates now approaching 85%. To achieve this patients undergo intensive treatment that usually takes 2.5-3.5 years involving on average 15 different chemotherapeutic drugs. In 1971, Donald Pinkel reported Total Therapy-Protocol V that used 5 drugs and cranial radiation therapy over a similar time period. Today, one half of these patients (Pinkel's children) remain alive and free of leukaemia. AIM: The aim of this study was to evaluate the impact post-induction minimal residual disease (MRD) levels had on survival and its relationship with the more established clinical and biological prognostic predictors of outcome in the hope of identifying a subgroup of patients that are at very low risk of failure. METHODS: A retrospective review of 250 Irish children with ALL was carried out. MRD status after 28 days of induction chemotherapy and other known predictors of outcome were correlated with 5 year event-free survival (EFS). RESULTS: MRD status was the strongest predictor of outcome with 5 year EFS rates greater that 90% seen in those patients with low-risk MRD and this was associated with TEL/AML1 rearrangement, high hyperdiploidy (HH) karyotype and female gender. CONCLUSION: Both MRD and karyotype are powerful determinants of outcome in childhood ALL. Therefore, it is reasonable to conclude that the majority of children cured by Pinkel et al. in the late 1960s were most likely composed of low-risk MRD, TEL/AML1 and HH patients.

ABSTRACT

PURPOSE: To investigate clinical, demographic and dietary factors associated with constipation in a sample of community dwelling people with Parkinson's disease, recruited through a specialist outpatient clinic. Partners/carers provided a convenience control group. SCOPE: Participants completed a baseline questionnaire (background information, diet and exercise, activities of daily living: mobility and manual dexterity, health-related quality of life (SF-12), stool frequency and characteristics, extent of concern due to constipation, laxative taking), and a four-week stool diary. The Rome criterion was used to determine constipation status. Multiple regression methods were used to explore the correlates of constipation. Baseline data were provided by 121 people with Parkinson's, (54 controls), of whom 73% (25%) met the Rome criterion. Prospective diary data from 106 people with Parkinson's (43 controls) showed lower proportions: 35% (7%) meeting the Rome criterion. Among all study subjects, i.e. Parkinson's patients and controls taken together, the presence of constipation is predicted by having Parkinson's disease (p = .003; odds ratio 4.80, 95% CI 1.64-14.04) and mobility score (p = .04; odds ratio 1.15, 95% CI 1.01-1.31), but not by dietary factors. Amongst people with Parkinson's constipation is predicted by number of medications (p = .027). Laxative taking masks constipation, and is significantly associated with wearing protection against bowel incontinence (p = .009; odds ratio 4.80, 95% CI: 1.48-15.52). CONCLUSIONS: Constipation is disease-related, not a lifestyle factor. More research is needed on optimal management and laxative use.

ABSTRACT

BACKGROUND: The molecular events leading to actinic keratosis (AK) are not well understood. OBJECTIVE: To identify and compare gene expression changes in AK lesions and in sun-exposed nonlesional skin and to determine the effect of imiquimod 5% cream on these changes. METHOD: A double-blind, vehicle-controlled, randomized study was conducted to evaluate the molecular changes in AK treated with imiquimod. Seventeen male subjects with >/= 5 AK lesions on the scalp applied vehicle or imiquimod three times a week for 4 weeks. Gene expression analysis using Affymetrix oligonucleotide arrays was performed on shave biopsies of lesions taken before and after treatment. Confocal microscopy was performed on the study area as an adjunctive diagnostic procedure. RESULTS: We identified gene expression changes which occur in sun-exposed, nonlesional skin as well as in AK lesions. These changes include, but are not limited to, the overexpression of oncogenic and proliferative genes and diminished expression of tumour suppressor genes. The gene expression changes observed in AK lesions and in sun-exposed, nonlesional skin were consistent with the confocal microscopy observations, which showed abnormalities in the sun-exposed, nonlesional skin, similar in nature but less pronounced than abnormalities seen in AK. Imiquimod partially or totally reversed the aberrant expression of some of the genes observed in AK, consistent with clearing of lesions and normalization of confocal cellular images. CONCLUSIONS: The data show that profound gene expression changes occur in sun-exposed, nonlesional skin which progress further in AK lesions. The data also suggest that imiquimod may play a role in normalizing gene expression and cellular morphology in sun-damaged skin.

ABSTRACT

Bio-ontology is a formal representation of biological concepts that is used in the interchange of communication between computers and humans alike. They can then be used in the formulation and retrieval of knowledge. In developing a knowledge-based system for Parkinson's Disease, a procedure of knowledge map was used to capture and harness the intellectual resources of an organization, and new paradigms for knowledge mapping were also formulated. Knowledge bases for symptoms and drugs, physiotherapy, speech and language therapy, and dieting that affect patient care were developed. Finally, the knowledge bases were merged to form a single central repository of knowledge base.

ABSTRACT

OBJECTIVES: To survey students aged 16-18 years in secondary education establishments in one school district in the south of England in order to: assess knowledge about the importance of blood pressure (BP) for health; investigate associations between knowledge and health-related behaviours; and explore home, school and health service influences on knowledge. STUDY DESIGN: Observational. METHODS: Self-reported data from a structured questionnaire administered to convenience samples of students in schools were analysed by Chi-squared tests and multiple linear regression. The questionnaire assessed knowledge about BP risks, symptoms, consequences and measurement, and collected information on BP-related instruction, health behaviours (smoking, exercise, alcohol and nutrition) and family background. RESULTS: A cross-section of 569 students completed questionnaires, representing 19.6% of the total age cohort. Most students recognized the major behavioural risks and consequences of high BP, but 104 (18.3%) could not describe how BP is measured, and 401 (88.1%) had no idea what a normal BP reading should be. In multivariate analysis, BP knowledge was associated with previous academic attainment, having received advice or instruction about BP, and having BP measured in the last 2 years. Family experience was not significant. Many students reported unhealthy behaviours: current smoker (n = 87, 15.3%); less than three exercise sessions per week (n = 172, 30.2%); and two portions or less of fruit/vegetables per day (n = 223, 39.2%). BP knowledge was significantly associated with regular exercise but not with other health-promoting behaviours. One hundred and twenty-one (21.3%) students acknowledged having received instruction about BP, mainly from doctors/nurses (32%) and schools (28%). CONCLUSION: Gaps in adolescents' knowledge about BP were identified. Greater awareness was associated with having received formal advice and instruction, so health services and schools could play an important part in improving BP knowledge among adolescents. More understanding of cumulative risks may encourage fuller engagement in health-promoting activities.

ABSTRACT

Research and 'common knowledge' has for many years accepted that education and feedback supplied to individuals during and immediately after workplace health assessments provides valuable information to workers about their health. Further, if more relevant and detailed information could be supplied then awareness and preventative action may increase proportionately. This research carried out with a rural Australian population has shown that preventative action did not increase in proportion to a corresponding increase in the amount and variety of information provided in connection with hearing health status. Two research groups underwent hearing tests, both with pure tone audiometry (PTA) while the second group also underwent otoacoustic emission (OAE) testing. Test results were presented to the subjects at the conclusion of their test session. An analysis of questionnaire responses at six week and twelve months follow up showed that more information did not result in increased preventative action. Barriers seem to exist such that individuals feel that they are not able to effectively act to reduce overall noise exposure. While self-efficacy initially increased, it declined to close to its initial value over the longer period. Other measures such as perceived susceptibility to hearing loss and the benefits of exposure reduction significantly increased and remained at the same increased level after twelve months. So, while overall awareness of noise and the risks of exposure were increased after both types of hearing test there was no increased hearing health benefit due to additional testing and hearing information.

ABSTRACT

BACKGROUND: Insulin-dependent diabetes mellitus, also known as type 1 diabetes, is a life-threatening condition and is the third most common chronic illness among young people. As a result of minimal or non-existent insulin production, people with diabetes must take over the normally automatic task of regulation of blood glucose levels. This is achieved by a complex regimen involving multiple, daily administrations of insulin coordinated with dietary intake and energy expenditure and monitored by blood glucose testing. OBJECTIVES: To examine the effectiveness of educational and psychosocial interventions for adolescents with type 1 diabetes designed to improve their diabetes management. Specifically, it addressed the following research questions: (1) Do educational and psychosocial interventions for adolescents with type 1 diabetes have beneficial effects on biological and psychosocial outcomes? (2) Are there types or features of interventions that have been shown to be more effective than others? (3) What evidence is there of the cost-effectiveness of interventions? METHODS: A search strategy was formulated, piloted and refined. Three journals were handsearched, 11 electronic databases were searched and personal contacts, flyers, conferences and websites were used to notify the research community of the review to access further literature. This process generated 10,535 abstracts, which, after screening, resulted in 367 articles identified for retrieval. This number was augmented by hand-searching, personal contact and exploding references, and a final total of 457 articles were scrutinised. Of these, 64 reports describing 62 studies were identified as empirical papers evaluating educational or psychosocial interventions. The relevant data were extracted from the papers and summary tables for each study were prepared. Where possible, effect sizes were computed for outcomes from studies that included a randomised control group (CG) and other relevant information. RESULTS: A descriptive analysis of the 62 studies was undertaken. Most studies (67.7%) were conducted in the USA and 41% were randomised controlled trials (RCTs), none of which were UK-based. Only 48% of the reports provided an explicit theoretical rationale for the intervention. The mean number of participants was 53.8. The studies took place in various settings, evaluated a variety of interventions, involved various interventionists, addressed various components and assessed the effects by a range of outcomes, including measures of metabolic control and psychological and behavioural outcomes. Follow-up assessments were relatively rare. RESULTS - THE EFFECTIVENESS OF INTERVENTIONS: The 25 RCTs were examined in more detail and three of the most effective were described in depth. Effect sizes could be calculated for 14 studies. The mean (pooled) effect size for psychosocial outcomes was 0.37 and 0.33 for glycated haemoglobin with outliers (0.08 without outliers), indicating that these interventions have small to medium beneficial effects on diabetes management outcomes. A narrative review of the 21 pre-post studies with no CG was performed, including evaluations of interventions conducted at summer camps, interventions for poorly controlled patients and educational interventions. All studies reported beneficial effects. RESULTS - COST-EFFECTIVENESS: Few studies addressed economic considerations associated with interventions, and the lack of information on costs and the diversity of outcomes included by investigators impeded cost- effectiveness comparisons. Shorter hospitalisation at diagnosis is at least as effective in achieving control and avoiding complications in adolescence as longer stays. Home care may result in improved outcomes but may not be cheaper than hospital care at diagnosis. Targeting poorly controlled subjects may reduce adverse events and hospitalisations and may be more cost-effective than generic interventions. There is a need for rigorous cost-effectiveness studies of educational and psychosocial interventions for adolescents with type 1 diabetes that include longer-term considerations. CONCLUSIONS: The following conclusions were drawn from this review: (1) Educational and psychosocial interventions have small to medium beneficial effects on various diabetes management outcomes. (2) Well-designed trials of such interventions are needed in the UK (no completed RCTs of educational or psychosocial interventions for adolescents with type 1 diabetes conducted in the UK were found). (3) The evidence, arising primarily from studies in the USA, provides a starting point for the design of interventions in the UK. (4) Quantitative and narrative analysis of the evidence suggested that interventions are more likely to be effective if they demonstrate the inter-relatedness of the various aspects of diabetes management.

ABSTRACT

This experiment investigated the accuracy with which the location of a probe tip relative to the tympanic membrane can be estimated by means of standing waves. The ear canal length of each ear of six adult subjects was measured with a probe tube using a tactile method. A 6-kHz warble tone was then generated, and the position of the standing wave notch in the ear canal was determined using a probe microphone by noting the place where the sound pressure level was at a minimum. The distance of the notch from the tympanic membrane was then calculated. The mean distance of the notch from the tympanic membrane was found to be 14.1 mm. It was concluded that this technique is reliable and suitable for clinical use when it is important that the probe tube be placed within a known distance of the eardrum for accurate measurement of real-ear aided gain.

ABSTRACT

Mucopolysaccharides derived from the husk of psyllium (Plantago ovata) have properties beneficial for wound cleansing and wound healing. Recent studies indicate that these mucopolysaccharides also limit scar formation. Our in vitro and in vivo studies aimed to investigate the mechanisms involved, e.g., fluid absorption, bacterial adherence and in vitro stimulatory effects on macrophages, which are pivotal in wound healing. The mucopolysaccharides contained in a sachet (Askina Cavity) or in a hydrocolloid mixture (Askina Hydro) were found to have a gradual and sustained absorbency over a period of 7 days, amounting to 4-6 times their weight in water. The swelling index was 9 mm after 312 h. Adherence of wound bacteria to the mucopolysaccharides started after 2 h and was more pronounced after 3 h. Semiquantitative measurements of bacterial adherence used centrifugation and subsequent optical density determinations of supernatant. These confirmed the strong adherence potential of psyllium particles. Lactic acid dehydrogenase staining of pretreated cultured human skin explants did not reveal toxicity of the mucopolysaccharides derived from psyllium husk. Langerhans' cell migration from the epidermis was negligible and interleukin-1 beta expression in the explants was not significant, supporting the very low allergenic potential of psyllium. The characteristics of mucopolysaccharide granulate derived from psyllium husk in Askina Cavity and Askina Hydro related to fluid absorption, bacterial adherence, biocompatibility, stimulation of macrophages, irritancy response and allergenicity showed an optimal profile, supporting the good clinical performance of wound healing products containing psyllium husk.

ABSTRACT

BACKGROUND: Granulomatous mastitis, a rare, benign breast condition characterized by granulomas and abscess formation, is mistaken frequently for inflammatory breast carcinoma. Although it has been reported in reproductive-age women, it is unusual in pregnancy. CASE: A 25-year-old black gravida 4 para 2 developed a tender, indurated 20 x 15 x 15 cm multilobulated breast mass at 17 weeks' gestation. After not responding to antibiotics and incisional drainage, the biopsy-proved granulomatous mastitis improved with corticosteroid treatment. A postpartum recurrence also responded to steroid therapy. CONCLUSION: Granulomatous mastitis is diagnosed clinically and histologically. Early recognition and initiation of steroid treatment might prevent repetitive, deforming breast biopsies.

ABSTRACT

OBJECTIVE: To evaluate the effectiveness of behavioral interventions for adolescents with type 1 diabetes based on a systematic review of the literature. RESEARCH DESIGN AND METHODS: The literature was identified by searching 11 electronic databases, hand-searching 3 journals from their start dates, and contacting individual researchers. Only articles that reported evaluations of behavioral (including educational and psychosocial) interventions for adolescents (age range 9-21 years) with type 1 diabetes that included a control group were included in the present review. Data summarizing the key features of the interventions and their effects were extracted from each article. Where possible, effect sizes for the randomized control trials (RCTs) were calculated. RESULTS: The search process identified 64 reports of empirical studies. Of these, 35 studies included a control group, and 24 were RCTs. Effect sizes could be calculated for 18 interventions. The overall mean effect size calculated across all outcomes was 0.33 (median 0.21), indicating that these interventions have a small- to medium-sized beneficial effect on diabetes management. Interventions that were theoretically based were significantly more effective than those that were not (P<0.05, 1-tailed). CONCLUSIONS: Research to date indicates that these interventions are moderately effective. Several methodological weaknesses to be avoided in future studies are noted. It is also recommended that investigators use the reach, efficacy, adoption, implementation, and maintenance (RE-AIM) framework to guide the design of future studies, which should result in more disseminable interventions. RE-AIM assesses the intervention's reach, or percent or representativeness of patients willing to participate; efficacy across a range of outcomes; adoption, or the percent and representativeness of settings willing to implement the intervention; implementation, or the consistency of the delivery of the intervention as intended; and maintenance, or the extent to which delivery of the intervention becomes a routine part of health care in the medical setting.

ABSTRACT

Sonographic guidance is commonly used in the biopsy of focal hepatic lesions, but biopsy for diffuse disease is often non-image-guided. We evaluated the safety and efficacy of real-time sonographically guided random core biopsy in the assessment of diffuse liver disease in 210 patients. The two most common indications for biopsy were viral hepatitis (in 113 patients) and elevated liver function test results of unknown cause (in 54 patients). Ultrasonography and pathology reports were reviewed retrospectively to determine number of needle passes and final diagnoses. Adequate tissue was obtained in all 210 patients, with 259 of 269 (96%) passes having been successful. Specimens were submitted for light microscopy and other tests as indicated. No difference in success rates was found for right and left lobe biopsies. No major complications occurred. Minor complications occurred in 10 of 210 (4.8%) patients and were self-limited. Sonographically guided core liver biopsy is a safe and effective method for the diagnosis of liver disease.
