Cost of Comorbid Alcohol and Drug Problems

The authors measured the comorbid effect of alcohol and other drug (AOD) problems on medical, surgical, and psychiatric inpatient charges and length of stay (LOS) in an urban hospital by use of retrospective study of hospital clinical computer data comparing AOD-affected patients with non-AOD-affected patients in terms of cost, diagnostic, demographic, and utilization variables (N = 14,768). Patients were men and women with and without comorbid history of AOD problems, admitted for medical, surgical, and psychiatric reasons. For 10 of the 20 most frequent Diagnosis-Related Groups (DRGs), total hospital charges and LOS were significantly lower in patients with comorbid AOD problems (P < 0.001). Overall, for the most frequent 20 DRGs, total charges and LOS remained significantly lower for the AOD group. Most physicians believed that AOD-affected patients were often less ill than non-AOD patients within the same DRG. Alcohol/drug-affected patients had robustly lower costs and LOS. Fragmentation of psychosocial costs and addiction treatment from general health care and the fee-for-service DRG system appear to financially reward acute-care hospitals to repeatedly treat secondary AOD sequelae without providing any apparent incentives for the treatment of the primary alcohol/drug condition itself.     

Characterization and Development of UCI 107, a Primary Human Ovarian Carcinoma Cell Line

We introduce a new epithelial ovarian carcinoma cell line (UCI 107) from a patient with papillary adenocarcinoma of the ovary who had not been previously treated. The growth characteristics, chemosensitivity, tumorgenicity, cytogenetics, antigen expression, and receptor status were examined. A standardized photometric assay was implemented to determine the response to single drug agents including doxorubicin (ADR), cisplatin (CDDP), and Taxol. Tumorgenicity was determined utilizing female athymic mice implanted either subcutaneously (sc) or intraperitoneally (ip) with 1 × 10⁷ UCI 107 cells. UCI 107 cells grow rapidly in culture with lag phase of approximately 48 hr, population doubling time of 24-36 hr, and saturation density of 4.8 × 10⁵ cells/cm². The 50% inhibitory concentration values for the chemotherapeutic agents were 0.170, 0.029, and 0.330 μM for ADR, Taxol, and CDDP, respectively. Nude mice produced ip tumors within 15 days, resulting in death from carcinomatosis 40-45 days postimplantation. Subcutaneous tumor nodules (100 mm³ were observed in nude mice 12-13 days post-tumor implantation reaching a maximum tumor volume of approximately 10,000 mm³ by Day 30. The cytogenetic composite karyotype is as follows: 46, X, der (X) t (X;7) (p11;q22), inv dup (1) (q12;q32), t (6;6;11;22) (p21.3;q16;q23.3;q13.3), del (13) (q14.1). The cell line expresses progesterone receptor, increased levels of p53 protein, and cytokeratins. It does not appear to express Her-2/neu protein, estrogen receptor, nor the CA 125 tumor marker. In conclusion, UCI 107 displays unique cellular properties which make it an attractive model for the study of ovarian cancer.     

Induction of HSP72 in Rat Liver by Chronic Ethanol Consumption Combined with Exercise: Association with the Prevention of Ethanol-Induced Fatty Liver by Exercise

Ethanol-induced fatty liver in rats was attenuated by repeated running exercise, and the protective effect of exercise was associated with the synergistic expression of heat shock proteins (HSP72). Rats were placed in four groups of six. The two ethanol-fed groups of rats received a liquid diet (Lieber-DeCarli formulation) in which 36% of the calories were derived from ethanol. One group remained sedentary (S/E), whereas the other was trained to run on a rodent treadmill at a speed of 27 m/min, 1 hr/day, 5 days/week, for 7 weeks (R/E). Two other groups–one exercised as previously mentioned (R/C) and one sedentary (S/C)–received control-liquid diets in which the ethanol was isocalorically substituted with a dextran/maltose mixture. The degree of fatty infiltration in liver sections stained with hematoxylin and eosin was graded on a 0–4 scale and the data analyzed by ANOVA on ranks. Ethanol significantly induced fatty infiltration in the S/E group, whereas fatty infiltration in the livers of the R/E group was not different from the S/C group. Electrophoresis and Western blotting of liver homogenates demonstrated that HSP72 was not expressed in either the S/C or S/E groups and was only slightly expressed in the R/C group. The combination of exercise and ethanol, however, resulted in an elevated expression of HSP72 in the R/E group. The content of HSP73 was unaffected by any treatment.     

Alpha2-HS glycoprotein phenotypes and quantitative hormone and bone measures in postmenopausal women

Summary It has been suggested that inherited traits play a role in the development of osteoporosis by providing a background for the modulation of gene expression. In this study, we examine the influence of the different alleles of alpha₂-HS glycoprotein (AHSG), a protein of the bone matrix, on quantitative estrogens, estrone and estradiol, and bone measures, bone area and density. Estrogens provide a protective effect against fractures in older women and were thus included in the analyses. Isoelectric focusing of AHSG from sera followed by immunoblotting was used to type 163 white post-menopausal women participating in a clinical trial of the effects of walking on bone loss. Plasma hormones were measured by a combination of extraction, column chromatography, and radioimmunoassay; bone measures on the dominant radius were determined with computerized tomography. Analysis of variance was done on estrogen and bone measures after controlling for the effects of age and body mass index. The two major alleles of AHSG result in three phenotypes, designated AHSG 1-1, AHSG 2-1, and AHSG 2-2. The AHSG 1-1 homozygote showed a decreased concentration of estradiol, the AHSG 2-2 homozygote showed an increased concentration, and the AHSG 2-1 heterozygote was intermediate (P=0.001). Estrone demonstrated a similar pattern in residual analysis although it did not reach statistical significance.

Fluoxetine Treatment of Depression Caused by Interferon-α

Interferon-α is the only approved and effective treatment for hepatitis C. Psychiatric side effects are common and have frequently required a decrease in dose or discontinuation of therapy. We here report a case of interferon-α-induced depression in a 40-yr-old man with hepatitis C successfully treated with the antidepressant fluoxetine, which allowed completion of interferon treatment.     

Sexual fantasies of heterosexual and homosexual men

Heterosexual men and homosexual men rated how arousing different sexual fantasies were and how often they had used these fantasies over the previous year. Within each group, sensual and genital same-orientation fantasies were more arousing than either public-sex or dominance-submissive fantasies, which in turn were more arousing than aggressive-sex fantasies. For both heterosexual and homosexual men the extent to which a fantasy was arousing correlated with the person's experience of the activity depicted in the fantasy. The frequency of use of a fantasy correlated positively with its arousal level but not always subtantially so. The results are discussed in the context of the mediating role of fantasy in human sexual arousal.
