Abstract

Death associated protein‑3 (DAP3) was identified as a responsive protein to interferon‑gamma‑induced cell death which possibly exerts this regulation by interacting with DAP3 binding cell Death enhancer‑1 (DELE1), a newly discovered mitochondrial stress protein in response to cell stress signals. Whilst DAP3 has been shown to be aberrantly expressed in several cancer types (i.e. breast cancer), little is known about the relationship between DAP3 and DELE1 in cancers. The present study examined the expression levels of both DAP3 and DELE1 in clinical colorectal cancers (CRCs), as well as their implication on chemoresistance and mechanism behind the action. Firstly, transcript levels of both DAP3 and DELE1 were quantitatively assessed in a clinical cohort of CRC (n=94). Tumour tissues had significantly higher levels of DAP3, but not DELE1 compared with normal tissues. Levels of DAP3 and DELE1 had a significant association with patient's clinical outcomes and local recurrence. DAP3 and DELE1 significantly correlated in normal colorectal tissues but not in tumour tissues. Secondly, the protein levels of DAP3 and DELE1 were evaluated in both normal and tumour colon tissues which showed that both proteins were highly aberrant in CRC tissues. In addition, both DAP3 and DELE1 at transcript and protein levels were identified as prognostic factors for patient's clinical outcomes. Furthermore, in

Abstract

Summary Background Pseudomonas aeruginosa is a ubiquitous and important opportunistic pathogen in immunocompromised or critically ill patients. Nosocomial P. aeruginosa outbreaks have been associated with hospital water sources. Aim To describe engineering interventions to minimize contamination of water outlets and the subsequent clinical impact. Methods New tap outlets were fitted at selected outlets across the intensive care unit (ICU). Laboratory testing demonstrated that, following artificial contamination with P. aeruginosa, these taps could be effectively decontaminated using a thermal washer-disinfector. Water samples were collected weekly from new outlets on the ICU over an eight-month period and tested for the enumeration of P. aeruginosa via membrane filtration. Surveillance of P. aeruginosa from clinical specimens was routinely undertaken. Findings Prior to the interventions, water sampling on ICU indicated that 30% of the outlets were positive for P. aeruginosa at any one time, and whole genome sequencing data suggested at least 30% transmission from water to patient. Since their installation, weekly sampling of the new tap outlets has been negative for P. aeruginosa, and the number of P. aeruginosa clinical isolates has fallen by 50%. Conclusion Installation and maintenance of tap outlets free of P. aeruginosa can substantially reduce the number of P. aeruginosa clinical isolates in an ICU.

Abstract

Minisatellites are composed of repetitive elements ranging from 9 to 100 base pairs (bp) in length. Although the function of these regions is not well understood, minisatellites have been used [...], D1S80 is a 16-bp variable number of tandem repeats minisatellite. We analyzed single nucleotide polymorphisms (SNPs) flanking this locus in a Tamil population. Alleles ranged from 15 through 41 repeats, with alleles 18 and 24 being predominant with frequencies of 31% and 34.5%, respectively, suggesting a bimodal allelic distribution. All the 18-repeat alleles are associated with Hinft(+) and Fnu4HI(-) restriction site polymorphisms at the 5' and 3' ends, respectively. Allele 24 is associated with Hinfl(-) and Fnu4HI(+). Of the alleles tested, 98.5% have a linkage of two specific SNP polymorphisms. If an allele is positive for HinfI, then it is negative for Fnu4HI, and if an allele is negative for HinfI, it is then positive for Fnu4HI, which demonstrates strong linkage disequilibrium between the two polymorphic SNPs. This suggests that reciprocal crossover is not involved in changes in the number of repeats, as few exchanges are seen in the flanking regions. The repeat allele-SNP association might be involved with the internal structure of the locus micropolymorphisms, possibly a double-strand break hotspot. KEY WORDS: D1S80 LOCUS, HINFI-FNU4HI POLYMORPHISM, MINISATELLITE, SNP, TAMIL POPULATION, LINKAGE DISEQUILIBRIUM.

15. Health and Wellness in an Active Economy

Abstract

There are two approaches to health and wellness that are explored throughout this chapter. The first is a socio-ecological response, where the recreation system has been focused on changing individual behaviour at the programmatic level. There is the realization that if programs were the single answer, then all the world's problems would be solved by now. What is needed is a much larger systemic response. The second approach relates to the co-creation of authentic and customized health and wellness solutions. Typically, the notion of health and wellness is viewed through the lens of the “expert” and a prescription model that is grounded in “the expert knows what is best for you.” The emerging model is one where the citizen is at the centre of the solution process. People desire the ability to feel more in control and make informed decisions about their health for themselves and their families. In this chapter, the authors explore this topic by reviewing a Canadian health and wellness action study.

Abstract

Purpose To investigate the natural history and genetic associations of drusenoid pigment epithelial detachment (DPED) associated with age-related macular degeneration (AMD). Design Retrospective analysis of a prospective cohort study. Participants Of the 4203 Age-Related Eye Disease Study 2 (AREDS2) participants, 391 eyes (325 participants) had DPED without late AMD at the time of DPED detection. Genetic analyses included 120 white AREDS2 participants and 145 Age-Related Eye Disease Study (AREDS) participants with DPED. Methods Baseline and annual stereoscopic fundus photographs were graded centrally to detect DPED, a well-defined yellow elevated mound of confluent drusen ≥433 μm in diameter, and to evaluate progression rates to late AMD: geographic atrophy (GA) and neovascular (NV)-AMD. Five single nucleotide polymorphisms (CFH [rs10611670], C3 [rs2230199], CFI [rs10033900], C2/CFB [rs114254831], ARMS2 [rs10490924]) and genetic risk score (GRS) group were investigated for association with DPED development. Kaplan–Meier analyses and multivariable proportional hazard regressions were performed. Main Outcome Measures Progression rates to late AMD and decrease of ≥3 lines in visual acuity (VA) from the time of DPED detection; association of rate of DPED development with genotype. Results Mean (standard deviation [SD]) follow-up time from DPED detection was 4.7 (0.9) years. DPED was associated with increased risk of progression to late AMD (hazard ratio [HR], 2.36; 95% confidence interval [CI], 1.98–2.82; P Conclusions This study replicates the results of previous natural history studies of eyes with DPED including the high rates of progression to late AMD and vision loss (regardless of progression to late AMD). The genetic associations are consistent with genes associated with AMD progression.

Abstract

AIM The number of advanced practice roles in the Australian health-care system is growing alongside contemporary health-care reforms. The present study aimed to evaluate the impact of introducing novel advanced practice dietitian roles in gastrostomy tube (g-tube) management and develop a competency framework for progressing opportunities in dietetics practice and policy. METHODS A questionnaire was distributed to service lead dietitians at six participating health-care networks at the completion of a dedicated advanced practice funding grant, and at 12-month follow up. Service changes (e.g. number of dietitians credentialed, service and adverse events, change in patient waiting times and staff satisfaction), enablers and barriers for the implementation of the novel roles (including pre-, during, and post-implementation), and clinical costing estimates to measure the financial impact on the health system were investigated. Participant feedback was also used to synthesise the development of an advanced scope of practice pathway to competency. RESULTS Responses were received from all participating health-care networks. Five out of six sites successfully implemented an advanced practice role in g-tube management, with conservative health system savings estimated at $185 000. Ten dietitians were credentialed, with a further seven trainees in progress. Over 200 service events were recorded, including those diverted from other health professionals. Enabling factors for successful introduction included strong executive and stakeholder support, resources provided by grant funding, and established credentialing governance committees. Barriers included recruitment and governance processes. CONCLUSIONS Opportunities exist for further expansion of advanced and extended practice roles for dietitians to meet future health-care demands.

Abstract

Purpose To analyze the prevalence, incidence, and clinical characteristics of eyes with geographic atrophy (GA) in age-related macular degeneration (AMD), including clinical and genetic factors affecting enlargement. Design Prospective cohort study within a controlled clinical trial. Participants Age-Related Eye Disease Study 2 (AREDS2) participants, aged 50–85 years. Methods Baseline and annual stereoscopic color fundus photographs were evaluated for GA presence and area. Analyses included GA prevalence and incidence rates, Kaplan-Meier rates, mixed-model regression, and multivariable analysis of the square root of GA, area adjusted for covariates, including clinical/imaging characteristics and genotype. Main Outcome Measures (1) Presence or development of GA; (2) change in the square root of GA area over time. Results At baseline, 517 eyes (6.2%) of 411 participants (9.8%) had pre-existing GA (without neovascular AMD), with the following characteristics: 33% central, 67% noncentral; and the following configurations: 36% small, 26% solid/unifocal, 24% multifocal, 9% horseshoe/ring, and 6% indeterminate. Of the remaining 6530 eyes at risk, 1099 eyes (17.3%) of 883 participants developed incident GA without prior neovascular disease during mean follow-up of 4.4 years. The Kaplan-Meier rate of incident GA was 19% of eyes at 5 years. In eyes with incident GA, 4-year risk of subsequent neovascular AMD was 29%. In eyes with incident noncentral GA, 4-year risk of central involvement was 57%. GA enlargement rate (following square root transformation) was similar in eyes with pre-existing GA (0.29 mm/year; 95% confidence interval 0.27–0.30) and incident GA (0.28 mm/year; 0.27–0.30). In the combined group, GA enlargement was significantly faster with noncentrality, multifocality, intermediate baseline size, and bilateral GA (P Conclusions Analyses of AREDS2 data on natural history of GA provide representative data on GA evolution and enlargement. GA enlargement, which was influenced by lesion features, was relentless, resulting in rapid central vision loss. The genetic variants associated with faster enlargement were partially distinct from those associated with risk of incident GA. These findings are relevant to further investigations of GA pathogenesis and clinical trial planning.

Abstract

The number of advanced practice roles in the Australian health-care system is growing alongside contemporary health-care reforms. The present study aimed to evaluate the impact of introducing novel advanced practice dietitian roles in gastrostomy tube (g-tube) management and develop a competency framework for progressing opportunities in dietetics practice and policy.A questionnaire was distributed to service lead dietitians at six participating health-care networks at the completion of a dedicated advanced practice funding grant, and at 12-month follow up. Service changes (e.g. number of dietitians credentialed, service and adverse events, change in patient waiting times and staff satisfaction), enablers and barriers for the implementation of the novel roles (including pre-, during, and post-implementation), and clinical costing estimates to measure the financial impact on the health system were investigated. Participant feedback was also used to synthesise the development of an advanced scope of practice pathway to competency.Responses were received from all participating health-care networks. Five out of six sites successfully implemented an advanced practice role in g-tube management, with conservative health system savings estimated at $185 000. Ten dietitians were credentialed, with a further seven trainees in progress. Over 200 service events were recorded, including those diverted from other health professionals. Enabling factors for successful introduction included strong executive and stakeholder support, resources provided by grant funding, and established credentialing governance committees. Barriers included recruitment and governance processes.Opportunities exist for further expansion of advanced and extended practice roles for dietitians to meet future health-care demands.

Abstract

Receptive anal intercourse and its association with sexually transmitted infections and human papillomavirus-related anal dysplasia has been well studied in various at-risk groups including men who have sex with men. However, the relationship between receptive anal intercourse and its potential complications in patients with inflammatory bowel disease is not fully understood. This narrative review discusses sexually transmitted infections and anal dysplasia in patients with inflammatory bowel disease who engage in receptive anal intercourse and the lack of evidence-based data to guide clinical practice. It addresses the psychosocial effects of stigmatization in these patients and its consequences in the clinical encounter. We review the need for sufficient data on infection, cancer prevention, and precoital and postcoital hygienic practices with hopes that future studies establish standardized guidelines and recommendations.

Abstract

Fecal microbiota transplant (FMT) is a highly efficacious treatment for recurrent or refractory Clostridium difficile infection (CDI); however, 10-20% of patients fail to achieve cure after a single FMT. The aim of this study was to identify risk factors associated with FMT failure and to develop and validate a prediction model for FMT failure.Patient characteristics, CDI history, FMT characteristics, and outcomes data for patients treated between 2011 and 2015 at three academic tertiary referral centers were prospectively collected. Early FMT failure was defined as non-response or recurrence of diarrhea associated with positive stool C. difficile toxin or PCR within 1 month of FMT. Late FMT failure was defined as recurrence of diarrhea associated with positive stool C. difficile toxin or PCR between 1 and 3 months of the FMT. Patient data from two centers were used to determine independent predictors of FMT failure and to build a prediction model. A risk index was constructed based on coefficients of final predictors. The patient cohort from the third center was used to validate the prediction model.Of 328 patients in the developmental cohort, 73.5% (N=241) were females with a mean age of 61.4±19.3 years; 19.2% (N=63) had inflammatory bowel disease (IBD), and 23.5% (N=77) were immunocompromised. The indication for FMT was recurrent CDI in 87.2% (N=286) and severe or severe-complicated in 12.8% (N=42). FMT was performed as an inpatient in 16.7% (N=54). The stool source was patient-directed donors in 40% (N=130) of cases. The early FMT failure rate was 18.6%, and the late failure rate was 2.7%. In the multivariable analysis, predictors of early FMT failure included severe or severe-complicated CDI (odds ratio (OR) 5.95, 95% confidence interval (CI): 2.26-15.62), inpatient status during FMT (OR 3.78, 95% CI: 1.55-9.24), and previous CDI-related hospitalization (OR 1.43, 95% CI: 1.18-1.75); with each additional hospitalization, the odds of failure increased by 43%. Risk scores ranged from 0 to 13, with 0 indicating low risk, 1-2 indicating moderate risk, and ≥3 indicating high risk. In the developmental cohort, early FMT failure rates were 5.6% for low risk, 12.7% for moderate risk, and 41% for high-risk patients. Of 134 patients in the validation cohort, 57% (N=77) were females with a mean age of 66±18.1 years; 9.7% (N=13) had IBD, and 17.9% (N=24) were immunocompromised. The early FMT failure rate at 1 month was 19.4%, with an additional 3% failing by 3 months. In the validation cohort, FMT failure rates were 2.1% for low risk, 16.1% for moderate risk, and 35.7% for high risk patients. The area under the receiver operating characteristic curve (AUROC) for FMT failure was 0.81 in the developmental cohort and 0.84 in the validation cohort.Severe and severe-complicated indication, inpatient status during FMT, and the number of previous CDI-related hospitalizations are strongly associated with early failure of a single FMT for CDI. The novel prediction model has good discriminative power at identifying individuals who are at high risk of failure after FMT therapy and may assist the treating physician in subsequent management plans.

Abstract

While the milieu of an inpatient facility is considered a treatment modality, extant literature focuses on the staff's role in creating the milieu rather than the patient's perception of it. Not since Goffman's Asylums (1961) has there been an in-depth examination of the phenomenal world of the hospitalized psychiatric patient. In this study, eight inpatients (ages 23 to 58) on the acute psychiatric unit of a metropolitan general hospital participated in phenomenological interviews about their experience of the environment. The essential meaning of the hospital was refuge from self-destructiveness. Prominent aspects of patients' experience within the place of refuge were three interrelated themes (like me/not like me, possibilities/no possibilities, and connection/disconnection). Universally, patients perceived peer-administered "therapy" as the most beneficial aspect of their hospitalization. They expressed longing for a deeper connection with staff and more intensive insight-oriented therapies. Although their needs for safety, structure, and medication were met, patients were not gaining greater understanding of their dysfunctional patterns of behavior. Renewed emphasis must be placed on the nurse-patient relationship and the therapeutic alliance.

Abstract

Background Hepatocyte growth factor (HGF) is a cytokine that has a profound effect on cancer cells by stimulating migration and invasion and acting as an angiogenic factor. In lung cancer, the factor also plays a pivotal role and is linked to a poor outcome in patients. In particular, HGF is known to work in combination with EGF on lung cancer cells. In the present study, we investigated the effect of a traditional Chinese medicine reported in cancer therapies, namely YangZheng XiaoJi (YZXJ) on lung cancer and on HGF mediated migration and invasion of lung cancer cells. Methods Human lung cancer cells, SKMES1 and A549 were used in the study. An extract from the medicine was used. Cell migration was investigated using the EVOS and by ECIS. Cell–matrix adhesion and in vitro invasion were assessed. In vivo growth of lung cancer was tested using an in vivo xenograft tumour model and activation of the HGF receptor in lung tumours by an immunofluorescence method. Results Both lung cancer cells increased their migration in response to HGF and responded to YZXJ by reducing their speed of migration. YZXJ markedly reduced the migration and in vitro invasiveness induced by HGF. It worked synergistically with PHA665752 and SU11274, HGF receptor inhibitors on the lung cancer cells both on HGF receptor activation and on cell functions. A combination of HGF and EGF resulted in a greater increase in cell migration, which was similarly inhibited by YZXJ, and in combination with the HGF receptor and EGF receptor inhibitors. In vivo, YZXJ reduced the rate of tumour growth and potentiated the effects of PHA665752 on tumour growth. It was further revealed that YZXJ significantly reduced the degree of phosphorylation of the HGF receptor in lung tumours. Conclusion YZXJ has a significant role in reducing the migration, invasion and in vivo tumour growth of lung cancer and acts to inhibit the migratory and invasive effects induced by HGF and indeed by HGF/EGF. This effect is likely attributed to the inhibition of the HGF receptor activation. These results indicate that YZXJ has a therapeutic role in lung cancer and that combined strategy with methods to block HGF and EGF should be considered.

Abstract

A major factor controlling the metastatic nature of cancer cells is their motility. Alterations in the signalling pathways controlling its regulation can lead to tumor cell invasion and metastasis. Directional motility involves protrusion of the cell's leading edge, via formation of filopodia and lamellipodia, adhesion to the substrate followed by tail retraction and de-adhesion. Rho GTPase binding proteins function as activators of the actin cytoskeleton and are key players in the transendothelial migration of cancer cells. Activation of the specific GTPases Rho, Rac1 and Cdc42 results in formation of actin stress fibres, membrane ruffles, lamellipodia and filopodia respectively and in cortical actin assembly. Pathways through which Rho GTPases elicit these effects are through direct interaction with members of the Wiskott-Alrich Syndrome Protein (WASP) family which stimulates structures such as lamellipodia and filopodia. The present review explores the role and function of Rho GTPases, WASP and WAVE in cancer metastasis.
