An investigation of scale effects in family substance abuse treatment programs

This short report investigates scale effects in family substance abuse treatment programs. In Massachusetts, the family substance abuse treatment programs were much more costly than other adult residential treatment models. State officials were concerned that the "scale" or size of these programs (averaging just eight families) was too small to be economical. Although the sample size (just nine programs) was too small to permit reliable inference, the data clearly signalled the importance of "scale effects" in these family substance abuse treatment programs. To further investigate scale effects in family substance abuse treatment programs, data from the Center for Substance Abuse Treatment's (CSAT's) Residential Women and Children and Pregnant and Postpartum Women (RWC-PPW) Demonstration were re-analyzed, focusing on the relationship between cost per family-day and the estimated average family census. This analysis indicates strong economies of scale up until an average family census of about 14, and less apparent scale effects beyond that point. In consideration of these and other study findings, a multidisciplinary interagency team redesigned the Massachusetts' family treatment program model. The new programs are larger than the former family treatment programs, with each new program having capacity to treat 11 to 15 families depending on family makeup

An ongoing process: A qualitative study of how the alcohol-dependent free themselves of addiction through progressive abstinence

<p>Abstract</p> <p>Background</p> <p>Most people being treated for alcoholism are unable to successfully quit drinking within their treatment programs. In few cases do we know the full picture of how abstinence is achieved in Taiwan. We tracked processes of abstinence in alcohol-dependency disorders, based on study evidence and results. This research explores the process of recovery from the viewpoint of the alcohol-dependent.</p> <p>Methods</p> <p>Semi-structured interviews were conducted in two different settings, using purpose sampling, during 2003-2004. The data were analyzed using content analysis. Participants were 32 adults, purposefully selected from an Alcoholics Anonymous group and a psychiatric hospital in North Taiwan.</p> <p>Results</p> <p>We found that the abstinence process is an ongoing process, in which the alcohol-dependent free themselves of addiction progressively. This process never ends or resolves in complete recovery. We have identified three stages in the struggle against alcoholism: the Indulgence, Ambivalence and Attempt (IAA) cycle, in which the sufferer is trapped in a cycle of attempting to give up and failing; the Turning Point, in which a Personal Nadir is reached, and the Ongoing Process of abstinence, in which a constant effort is made to remain sober through willpower and with the help of support groups. We also discuss Influencing Factors that can derail abstinence attempts, pushing the sufferer back into the IAA cycle.</p> <p>Conclusion</p> <p>This study provides important points of reference for alcohol and drug service workers and community healthcare professionals in Taiwan, casting light on the abstinence process and providing a basis for intervention or rehabilitation services.</p

Front Matter

The carbohydrate Galα1-3Galβ1-(3)4GlcNAc-R (α-Gal) is produced in all mammals except for humans, apes and old world monkeys that lost the ability to synthetize this carbohydrate. Therefore, humans can produce high antibody titers against α-Gal. Anti-α-Gal IgE antibodies have been associated with tick-induced allergy (i.e. α-Gal syndrome) and anti-α-Gal IgG/IgM antibodies may be involved in protection against malaria, leishmaniasis and Chagas disease. The α-Gal on tick salivary proteins plays an important role in the etiology of the α-Gal syndrome. However, whether ticks are able to produce endogenous α-Gal remains currently unknown. In this study, the Ixodes scapularis genome was searched for galactosyltransferases and three genes were identified as potentially involved in the synthesis of α-Gal. Heterologous gene expression in α-Gal-negative cells and gene knockdown in ticks confirmed that these genes were involved in α-Gal synthesis and are essential for tick feeding. Furthermore, these genes were shown to play an important role in tick-pathogen interactions. Results suggested that tick cells increased α-Gal levels in response to Anaplasma phagocytophilum infection to control bacterial infection. These results provided the molecular basis of endogenous α-Gal production in ticks and suggested that tick galactosyltransferases are involved in vector development, tick-pathogen interactions and possibly the etiology of α-Gal syndrome in humans.This research was supported by the Consejería de Educación, Cultura y Deportes, JCCM, Spain, project CCM17-PIC-036 (SBPLY/17/180501/000185).

Trends in the Use of Feeding Tubes in North Carolina Hospitals: 1989 to 2000

OBJECTIVE: National data describing the placement of feeding tubes demonstrated a rapid increase in use in the early and mid-1990s. In the past several years, substantial concerns have arisen regarding the appropriateness of the procedure in many chronically ill patients. The purpose of this study is to determine whether the use of feeding tubes has continued to increase through the 1990s despite these widely publicized concerns. DESIGN: Repeated measure cross-sectional study of the North Carolina Discharge Database. SETTING: Analyses of all nonfederal hospital inpatient admissions in North Carolina. MEASUREMENTS AND MAIN RESULTS: We examined the absolute numbers and rates of feeding tube placements from 1989 to 2000. The rate of feeding tube placement increased from 59/100,000 persons in 1989 to 94/100,000 persons in 2000, an overall 60% increase with slowing in the rate of increase in the late 1990s. However, when outpatient procedures were included, the increase in tube feeding continued throughout the 11-year period of observation. The increase was due to an increase in utilization within all hospitals over the time period. Utilization did not differ between profit and not for profit hospitals. The relative growth rate of inpatient feeding tube placement did not differ by age group but the absolute increase was greatest in those age 75 years and over. CONCLUSIONS: Our study demonstrates that the use of feeding tubes has continued to increase through the 1990s. This increase occurred despite ongoing controversy in the medical literature about feeding tube placement in chronically ill patients
