Changing Health Practices Through Research to Practice Collaboration: The Farm Dinner Theater Experience

Production agriculture ranks as one of the most hazardous occupations in the United States, with older producers suffering 3.5 times the fatalities compared with their younger counterparts. Previous interventions have not significantly improved the health or work behaviors of farmers. Through careful collaboration among academics and Cooperative Extension agents, we developed, tested, and expanded a unique educational experience, Farm Dinner Theater (FDT), for farmers aged 45 years and more and their families across three states (n = 8 communities, 573 participants). More than 50% of the participants made health or safety changes following the theater. Communities requested more theater events, noting the realism and applicability of the content and the engaging atmosphere for discussion. Participants remarked that the theater should be used across all age-groups. The FDT project created a community of "champions" that synergized the initial research project and fostered expansion and sustainability of the intervention. Process evaluation guided refinement of the theater intervention and built trust, respect, and further cooperative work among all collaborators. Members of the FDT partnership have received national recognition and funding to upscale the concept. The number of FDTs has expanded under local leadership. A toolkit that resulted from the project is available to the public and is constantly updated as more adopters contribute insight and scripts. This article describes the collaborative theater concept and demonstrates how sustained translation from research to practice can be accomplished through continued community engagement, collaboration, and outreach.

Are all RAS mutations the same? Coexisting KRAS and NRAS mutations in a caecal adenocarcinoma and contiguous tubulovillous adenoma

Mutations of the human Kirsten rat sarcoma viral oncogene homologue (KRAS) and the highly homologous human neuroblastoma RAS viral oncogene homologue (NRAS) are associated with resistance to antiepidermal growth factor receptor therapies in patients with colorectal cancer. In this report, we describe a caecal adenocarcinoma that contains both KRAS c.35G>T (G12V) and NRAS c.34G>A (G12S) mutations. The adenocarcinoma arises from a contiguous high-grade tubulovillous adenoma, which also carries the identical KRAS and NRAS mutations, supporting their common origin. While KRAS mutations are common in colorectal cancers, NRAS mutations are relatively rare and the coexistence of multiple RAS mutations is not documented, presumably reflecting similar functions of wild-type and mutant forms of RAS. Recent experimental evidence has suggested that KRAS and NRAS may in fact mediate distinct biological processes in the colon, and this unusual case potentially illustrates the hypothesis clinically. Characterisation of the diverse and divergent functions of RAS family members and mutant forms of RAS in the colon form important considerations for the development of RAS-targeting therapeutics.

Minor pathological changes are induced by naltrexone-poly(DL-lactide) implants in pregnant rats

Oral naltrexone is used to treat alcohol and heroin dependence but is associated with poor patient compliance. Sustained-release preparations have been developed to overcome noncompliance. Many sustained-release preparations are composed of polymers combined with naltrexone. Limited data indicate that polymers induce variable levels of tissue reactivity and that naltrexone may increase this effect. A slow-release subcutaneous naltrexone-poly (DL-lactide) implant is currently being trialed to treat heroin dependence in Western Australia. A minority of women fall pregnant and, although tissue reactivity in nonpregnant humans is relatively minor, detailed chronological data during pregnancy are lacking. Histological changes in pregnant rats were assessed; a single active tablet containing poly[trans-3,6-dimethyl-1,4-dioxyane-2,5-dione] (DL-lactide) loaded with 25 mg of naltrexone was implanted subcutaneously, and tissue response was compared with inactive polymer implantation. Rats were timed mated at 13-26 days postimplant. Tissue assessment up to 75 days by a pathologist showed that naltrexone induced chronic inflammatory response in a dose-dependent manner, although still at a low level. Furthermore, for inactive implants, minimal foreign body reaction and fibrosis, together with low-level inflammation, suggested good long-term biocompatibility. We conclude that the Australian naltrexone-poly(DL-lactide) implant is tolerated in pregnant rats, reinforcing its potential role for managing alcohol and heroin dependence in pregnant humans.

Translating the REACH caregiver intervention for use by area agency on aging personnel: the REACH OUT program

PURPOSE

The aim of this study was to translate the evidence-based Resources for Enhancing Alzheimer's Caregiver Health (REACH) II intervention for use in 4 Area Agencies on Aging (AAAs). A secondary aim was to examine possible moderators of treatment outcome.

DESIGN AND METHODS

We used a quasi-experimental pre-post treatment design with no control group. A partnership was formed between the Alabama Department of Senior Services and the University of Alabama. The partnership trimmed the REACH II intervention used in the clinical trial for feasible use in a social service agency. The condensed REACH intervention, termed REACH OUT, was delivered to 272 dementia caregivers during 4 home visits and 3 phone calls for a period of 4 months. The assessment examined pre-post treatment effects on a number of outcomes, including care recipient risk, mood, memory, and behavior problems; caregiver stress and emotional well-being; caregiver health; and program satisfaction. All aspects of the program except for training, periodic consultation, and data analysis were controlled by the AAA staff.

RESULTS

Analyses were conducted on the 236 dyads that completed at least 3 of the 4 planned sessions. Significant positive pre-post effects were found on caregiver subjective burden, social support, caregiver frustration, depression, caregiver health, care recipient behavior problems and mood, and 2 of 4 care recipient risk behaviors. Site of intervention and certain participant characteristics (e.g., caregiver relationship) moderated several pre-post differences. A caregiver survey and interventionist focus group reported high acceptability of the program

IMPLICATIONS

This project suggests that the REACH II intervention can be modified for feasible and effective use in AAAs. The next step is to integrate the intervention into usual service delivery to achieve sustainability.

Histological changes over time around the site of sustained release naltrexone-poly(dl-lactide) implants in humans

In order to assess the histological tissue changes over time around the site of implant, tissue biopsies were taken at 1 to 38 months post-implant from 54 (34 male) consenting human subjects who had received the Australian subcutaneous naltrexone-poly(DL-lactide) implant for heroin dependence. The implant consists of multiple tablets containing compressed naltrexone-poly[trans-3,6-dimethyl-1,4-dioxane-2,5-dione] (DL-lactide) loaded microspheres. Assessment of tissue samples by pathologists showed an early phase (up to 12 months post-implant) of inflammation, foreign body reaction, and fibrosis. This subsided gradually over the next 12 months until tissue returned to normal by 25+ months. Sufficient evidence was not available to conclude that the poly(DL-lactide) implant matrix was totally biodegradable within the study period. While implant material was not identified in most of the latter biopsies, its presence was noted in one biopsy at 26 months post-implant. Nevertheless the study results did demonstrate the implant's biocompatibility by the lack of inflammation, foreign body reaction, and fibrosis detected by 25+ months. It seems highly probable that surgical technique rather than the implant itself was associated with the additional finding of fat necrosis. Moderate fat necrosis was observed as a common feature of biopsies carried out during the first 6 months following implant. It subsided to mild levels over the next 18 months, and was notably absent by 25+ months. The results of the study indicated that the Australian naltrexone-poly(DL-lactide) implant is well tolerated and may have a role for use in the management of medical conditions such as heroin dependence.

Transmission electron microscopic pathoanatomy of congenital trigger thumb

Previous studies of trigger digits in children have been limited to gross morphology and light-microscopic histology. Nine children with 11 trigger thumbs formed a preliminary study group for electron-microscopic evaluation of tendon nodules and A-1 pulleys. This pathoanatomic investigation was not previously reported. Comparison was made with light-microscopic sections. Large amounts of mature collagen was observed. Fibroblasts with prominent rough endoplasmic reticulum were present. No degenerative or inflammatory changes were noted in either tendon or sheath. We believe that although the etiology of trigger digits is still uncertain, an infectious, inflammatory, or degenerative process is unlikely.

IgA nephropathy and thin basement membrane disease in association with Crohn disease

There have been a wide variety of reported renal parenchymal diseases associated with inflammatory bowel disease, ranging from interstitial nephritis to amyloidosis to immune complex glomerulonephritis. Two pediatric cases of renal parenchymal pathology in association with Crohn disease are presented. The first is an 11-year-old child who presented with recurrent bouts of gross hematuria, biopsy-proven IgA nephropathy, and later developed Crohn disease 4 years after the initial presentation. Her renal function is normal with persistent isolated microscopic hematuria. The second case is that of a 9-year-old male who presented with the classic gastrointestinal manifestations of Crohn disease, later developed hematuria and proteinuria, and was found on a renal biopsy to have thin basement membrane disease. There have been several reported cases of IgA nephropathy associated with inflammatory bowel disease; but to our knowledge, this is the first case of thin basement membrane disease occurring in conjunction with Crohn disease. Discussion focuses on the relationship of IgA nephropathy with inflammatory bowel disease with additional comments on thin basement membrane disease.

Involving the patient can free resources

Involving the patient in the scheduling of theatres by a Diary Booking System improves patient choice and thus the quality of service offered. To assess the feasibility and cost effectiveness of such a system, a trial was conducted within ENT surgery. One consultant's theatre schedules were analysed before and after the introduction of a diary booking system. A second consultant's schedules, not using a diary booking system, were analysed to confirm the absence of seasonal variation or other factors. The trial consisted of three months' schedules before introduction and three months after introduction. The feasibility of the system was confirmed. The trial reduced cancellations by 32% and failures to attend by 68%. The introduction of the Diary Booking System increased the number of operations conducted by nearly one per session.

Effects of taipan (Oxyuranus scutellatus) venom on erythrocyte morphology and blood viscosity in a human victim in vivo and in vitro

The case of a snake handler with envenoming due to Australian taipan (Oxyuranus scutellatus) showing marked morphological changes in his red blood cells is presented. The red cells underwent sphero-echinocytic transformation and in subsequent experiments in vitro the effects of taipan venom on red cells were further characterized. Taipan venom induced sphero-echinocytic transformation at nanogram/ml concentrations and led to a marked increase in whole blood viscosity. These changes have not been featured in previous reports of taipan envenomation and are reported to highlight the diagnostic value of blood film examination in cases of suspected envenomation. The significance of the hyperviscosity, and consequent reduction in blood fluidity, is unknown and requires further investigation.

Lack of significant long-term sequelae following traumatic myocardial contusion

We assessed the possibility of long-term functional cardiac sequelae in patients who had sustained a traumatic myocardial contusion (group 1) by comparing this group with a cohort group of patients with similar traumatic injuries but exclusive of the cardiac component (group 2). More than one year following injury, patients in group 1 were qualitatively indistinguishable from patients in group 2 according to the New York Heart Association classification. Both the left and the right ventricular ejection fractions, less in group 1 than in group 2 immediately following trauma, were similar between groups during follow-up study at rest. During exercise to maximal work load at follow-up, changes in the mean right and left ventricular ejection fractions were also similar between the two patient groups. We therefore concluded that traumatic myocardial contusion to the left and/or right ventricle almost always resolves without significant functional sequelae within one year of injury.

Educational expansion, curriculum reform and psychological theory: Australia in the 1930s

The educational policy emerging from the 1930s Depression in Aus tralia is reviewed, in order to show how its emphasis on curriculum reform and diversity of courses, concentrated in State secondary schools, was premised on contemporary understandings about 'natural' individual ability. The psychological theory of individual differences, which developed during the first three decades of this century, constructed State school users as a social group having dif ferent educational needs from the traditional users of secondary education. However, the evidence for these differences was drawn from the actual operation of the State system, its stage of develop ment and the level of resources it attracted, and the way it functioned relative to the sphere of educational activity already car ved out by the private system.

Organization and operation of a home parenteral nutrition program with emphasis on the pharmacist's role

A home parenteral nutrition program was organized at Mayo Clinic-Rochester Methodist Hospital in 1975. To date, 26 patients with chronic malnutrition usually due to either severe short bowel syndrome or extensive Crohn's disease have been trained in home parenteral nutrition for a total treatment period of 430 patient-months. Home parenteral nutrition is an attractive alternative for these patients in that it dramatically improves nutrition, promotes rehabilitation at home, and probably decreases long-term expenses. The numerous medical, psychosocial, and financial problems confronting patients on home parenteral nutrition are managed through a multispecialty team consisting of physicians, pharmacists, nurse, social worker, dietitian, physiatrist, psychiatrist, and business manager. The pharmacist is the person with whom the patient has the most contact during a 2-week training period. In addition to patient education, the pharmacist coordinates the transition to home care, offers in-service education on home parenteral nutrition to nurses and house officers, tests and evaluates the equipment, coauthors a training manual, and edits a quarterly newsletter to patients who are on home parenteral nutrition.
