Using Acceptance and Commitment Therapy during Methadone Dose Reduction: Rationale, Treatment Description, and a Case Report.

Many clients who undergo methadone maintenance (MM) treatment for heroin and other opiate dependence prefer abstinence from methadone. Attempts at methadone detoxification are often unsuccessful, however, due to distressing physical as well as psychological symptoms. Outcomes from a MM client who voluntarily participated in an Acceptance and Commitment Therapy (ACT) - based methadone detoxification program are presented. The program consisted of a 1-month stabilization and 5-month gradual methadone dose reduction period, combined with weekly individual ACT sessions. Urine samples were collected twice weekly to assess for use of illicit drugs. The participant successfully completed the program and had favorable drug use outcomes during the course of treatment, and at the one-month and one-year follow-ups. Innovative behavior therapies, such as ACT, that focus on acceptance of the inevitable distress associated with opiate withdrawal may improve methadone detoxification outcomes.

Occupational beryllium exposure: Reconciling federal policies, regulations and contractor implementation guides to protect worker health

Beryllium is a widely distributed, highly toxic metal. When beryllium particulates enter the body, the body's defense mechanisms are engaged. When the body's defenses cannot easily remove the particulates, then a damage and repair cycle is initiated. This cycle produces chronic beryllium disease (CBD), a progressive, fibrotic respiratory involvement which eventually suffocates exposed individuals. ^ Beryllium disease is an occupational disease, and as such it can be prevented by limiting exposures. In the 1940s journalists reported beryllium deaths at Atomic Energy Commission (AEC) facilities, the Department of Energy's (DOE) predecessor organization. These reports energized public pressure for exposure limits, and in 1949 AEC implemented a 2 μg/m3 permissible exposure limit (PEL). ^ The limits appeared to stop acute disease. In contrast, CBD has a long latency period between exposure and diagnosable disease, between one and thirty years. The lack of immediate adverse health consequences masked the seriousness of chronic disease and pragmatically removed CBD from AEC/DOE's political concern. ^ Presently the PEL for beryllium at DOE sites remains at 2 μg/m 3. This limit does not prevent CBD. This conclusion has long been known, although denied until recently. In 1999 DOE acknowledged the limit's ineffectiveness in its federal regulation governing beryllium exposure, 10 CFR 850. ^ Despite this admission, the PEL has not been reduced. The beryllium manufacturer and AEC/DOE have a history of exerting efforts to maintain and protect the status quo. Primary amongst these efforts has been creation and promotion of disinformation within peer reviewed health literature which discusses beryllium, exposures, health effects and treatment, and targeting graduate school students so that their perspective is shaped early. ^ Once indoctrinated with incorrect information, professionals tend to overlook aerosol and respiratory mechanics, immunologic and carcinogenic factors. They then apply tools and perspectives derived from the beryllium manufacturer and DOE's propaganda. Conclusions drawn are incorrect. The result is: health research and associated policy is conducted with incorrect premises. Effective disease management practices are not implemented. ^ Public health protection requires recognition of the disinformation and its implications. When disinformation is identified, then effective health policies and practices can be developed and implemented. ^

A DESCRIPTION AND EVALUATION OF EDUCATIONAL PROGRAMS FOR HEALTH MANPOWER IN NIGERIA

A descriptive study of the current educational programs of selected health personnel in Nigeria was made in 1986. Data on the content of educational programs was obtained from personal communication with the Heads of the various institutions and from their published materials (catalogs, course outlines and program descriptions). Adequacy of these programs was judged in the light of current health problems and needs of the population. Evaluation was based on the following criteria: (a) Selection of students to maximize their usefulness in the provision of health care. (b) Relevance of the curriculum to the tasks the trainee will be called upon to perform. (c) Types of courses that focus on community health needs. Using official reports, the health situation in the country was described to give a relative priority of health services.^ Findings indicate the following: (1) Health conditions in Nigeria are related to a high prevalence of illness and disease, unsanitary living conditions, a high ratio of infant mortality and a shortage of public health services. Priority needs for improvement call for attitudinal and environmental changes. (2) All health training programs have improved the relevance of education to community health needs by strengthening practical field experience, and teaching those courses which focus on disease prevention. (3) Prospective nurses and community health workers are selected on the basis of a number of personal and intellectual characteristics, but academic performance alone is the criterion for medical students. (4) The curriculum in the medical school needs to be restructured to cut back on time devoted to enriching the medical "background". Basic sciences need better integration with hospital work. (5) Managerial and organization courses have been well incorporated into the nursing and community health workers' curricula. (6) There is a marked overlap in the tasks the community health workers are expected to perform. This causes some redundancy in having four separate categories of these health personnel. ^

AN EPIDEMIOLOGIC DESCRIPTION AND ANALYSIS OF LOST WORKDAY OCCUPATIONAL BURN INJURIES

Background research consisted of a hospital case series of all adult burn patients (n = 162) admitted to John Sealy Hospital's burn unit from January 1978 to June 1979. Comparisons between occupationally and nonoccupationally burned adults demonstrated that occupationally burned adults were significantly more likely to have been active in the burn injury event and to have changed jobs during the prior year. They were significantly less likely to have physical or mental problems which contributed to sustaining the burn injury. Comparisons between occupational and nonoccupational burn injury events concluded that occupational burn injury events were significantly more likely to involve multiple sources of energy, sparks as the source of ignition and gases as the source of combustion. Other salient characteristics of occupational burn injuries indicated that subsequent research should focus upon lost workday occupational burns and other injuries sustained by blue-collar petrochemical workers employed in Galveston County, Texas.^ Subsequent research consisted of a historical cohort study of occupational injuries sustained in 1979 by a cohort of blue-collar petrochemical workers (n = 1771) who belonged to O.C.A.W. Local 4-449 in Texas City, Texas. Specific cohort injury rates included 15.08 occupational injuries per 100 person work-years, 11.98 lost workday occupational injuries per 100 person work-years, and 1.64 lost workday occupational burn injuries per 100 person work-years. Salient results from this study indicate that burn injuries are a very important type (in terms of both frequency and severity) of occupational injury sustained by blue-collar petrochemical workers, pipefitters are at greatest risk of lost workday injuries and lost workday burn injuries, company-specific experiences are comparable for lost workday occupational injuries, differences among company-specific nonlost workday occupational injury experiences may not be "safety-related", and minimal job-specific experience may not place employees at greater risk of lost workday burn injuries.^

Longitudinal and logistic analysis of endocrine hormone profiles, physical maturation, and candidate genes related to pubertal events in children

Children who experience early pubertal development have an increased risk of developing cancer (breast, ovarian, and testicular), osteoporosis, insulin resistance, and obesity as adults. Early pubertal development has been associated with depression, aggressiveness, and increased sexual prowess. Possible explanations for the decline in age of pubertal onset include genetics, exposure to environmental toxins, better nutrition, and a reduction in childhood infections. In this study we (1) evaluated the association between 415 single nucleotide polymorphisms (SNPs) from hormonal pathways and early puberty, defined as menarche prior to age 12 in females and Tanner Stage 2 development prior to age 11 in males, and (2) measured endocrine hormone trajectories (estradiol, testosterone, and DHEAS) in relation to age, race, and Tanner Stage in a cohort of children from Project HeartBeat! At the end of the 4-year study, 193 females had onset of menarche and 121 males had pubertal staging at age 11. African American females had a younger mean age at menarche than Non-Hispanic White females. African American females and males had a lower mean age at each pubertal stage (1-5) than Non-Hispanic White females and males. African American females had higher mean BMI measures at each pubertal stage than Non-Hispanic White females. Of the 415 SNPs evaluated in females, 22 SNPs were associated with early menarche, when adjusted for race ( p<0.05), but none remained significant after adjusting for multiple testing by False Discovery Rate (p<0.00017). In males, 17 SNPs were associated with early pubertal development when adjusted for race (p<0.05), but none remained significant when adjusted for multiple testing (p<0.00017). ^ There were 4955 hormone measurements taken during the 4-year study period from 632 African American and Non-Hispanic White males and females. On average, African American females started and ended the pubertal process at a younger age than Non-Hispanic White females. The mean age of Tanner Stage 2 breast development in African American and Non-Hispanic White females was 9.7 (S.D.=0.8) and 10.2 (S.D.=1.1) years, respectively. There was a significant difference by race in mean age for each pubertal stage, except Tanner Stage 1 for pubic hair development. Both Estradiol and DHEAS levels in females varied significantly with age, but not by race. Estradiol and DHEAS levels increased from Tanner Stage 1 to Tanner Stage 5.^ African American males had a lower mean age at each Tanner Stage of development than Non-Hispanic White males. The mean age of Tanner Stage 2 genital development in African American and Non-Hispanic White males was 10.5 (S.D.=1.1) and 10.8 (S.D.=1.1) years, respectively, but this difference was not significant (p=0.11). Testosterone levels varied significantly with age and race. Non-Hispanic White males had higher levels of testosterone than African American males from Tanner Stage 1-4. Testosterone levels increased for both races from Tanner Stage 1 to Tanner Stage 5. Testosterone levels had the steepest increase from ages 11-15 for both races. DHEAS levels in males varied significantly with age, but not by race. DHEAS levels had the steepest increase from ages 14-17. ^ In conclusion, African American males and females experience pubertal onset at a younger age than Non-Hispanic White males and females, but in this study, we could not find a specific gene that explained the observed variation in age of pubertal onset. Future studies with larger study populations may provide a better understanding of the contribution of genes in early pubertal onset.^

Description and analysis of variation in dairy product and concomitant nutrient purchases between Hispanic and non -Hispanic households using a panel of shoppers' purchase records

The purpose of this research was development of a method of estimating nutrient availability in populations as approximated by supermarket purchase records. Demographic information describing 12,516 panel households was obtained from a marketing and advertising program operated by H. E. Butt Grocery Company of San Antonio, Texas. A non-probability sample of 2,161 households meeting expenditure criteria was selected and all purchases of dairy products for this sample of households were organized into a database constructed to facilitate the retrieval, aggregation, and analysis of dairy product purchases and their nutrient contents. Two hypotheses were tested: (1) no difference would be found between Hispanic and non-Hispanic purchases of dairy product categories during the study period and (2) no difference would be found between Hispanic and non-Hispanic purchases of nutrients contained in those dairy products during the thirteen-week study period.^ Food purchase records were used to estimate nutrient exposure on a weekly, per capita basis for Hispanic and non-Hispanic households by linking some 40,000 dairy purchase Universal Product code (UPC) numbers with food composition values contained in USDA Handbook 8-1. Results of this study suggest Hispanic sample households consistently purchased fewer dairy products than did non-Hispanic sample households and consequently had fewer nutrients available from dairy purchases. While weekly expenditures for dairy products among the sample households remained relatively constant during the study period, shifts in the types of dairy products purchased were observed. The effect of ethnicity on dairy product and nutrient purchases was significant over the thirteen-week period. A database consisting of customer, household, and purchase information can be developed to successfully associate food item UPC numbers with a standard reference of food composition to estimate nutrient availability in a population over extended periods of time. ^
