CFO compensation influenced by organizational size, ownership.

Results of a 1995 compensation survey of healthcare organization chief financial officers (CFOs) indicate that the larger the organization for which the CFO works (as measured by operating revenues), the larger the CFO's compensation package. The survey findings show that CFOs who work for organizations with annual operating revenues of more than $199 million earn an average of $189,300 annually, while CFOs at organizations with operating revenues less than $50 million earn $76,400. Other factors influencing CFOs compensation, according to survey results, include education level, gender, and job responsibilities; geographic location of the employing organization; organizational type (multi-unit system, stand-alone hospital, etc.); and organizational ownership (physician-owned, not-for-profit, etc.) The survey was co-sponsored by the Healthcare Financial Management Association (HFMA) and Aetna Life Insurance and Annuity Company and conducted by Management Compensation Services, a division of Hewitt Associates LLC. It is the first HFMA survey to be devoted entirely to compensation. In previous years, compensation data were obtained as part of CFO profile survey findings.

Oxidative phosphorylation diseases and cerebellar ataxia.

Oxidative phosphorylation (OXPHOS) diseases can be caused by mutations in nuclear genes or mitochondrial DNA (mtDNA) genes. mtDNA mutations include complex mtDNA rearrangements in which large segments of mtDNA are duplicated or deleted and point mutations in which single nucleotide substitutions occur within transfer RNA (tRNA) genes, ribosomal RNA (rRNA) genes, or mitochondrial genes encoding OXPHOS polypeptides. Although over 30 pathogenic mtDNA point mutations and over 60 different types of mtDNA deletions are known (Shoffner and Wallace, 1995; Wallace et al., 1994), only a subset of these mutations are associated with cerebellar ataxia. This review focuses on the clinical, biochemical, and genetic features of OXPHOS diseases caused by mtDNA mutations in which ataxia is a common manifestation.

Use of hysteroscopy in addition to laparoscopy for evaluating chronic pelvic pain.

This study assessed whether hysteroscopy can provide information concerning the cause of chronic pelvic pain. We prospectively evaluated the findings in 547 consecutive patients who had laparoscopy to evaluate chronic pelvic pain at a large, referral-based clinic and outpatient suite of a suburban hospital. Forty-eight had previous hysterectomies. The remaining 499 had hysteroscopy during the same surgery and met the following qualifications: chronic pelvic pain, dysmenorrhea, dyspareunia, dysuria, back pain, pelvic pressure or dyschezia for a duration greater than six months and previous failed medical therapy. When endometriosis was the primary diagnosis at laparoscopy, hysteroscopy revealed abnormalities in 62 (32.5%) of 191 patients. At hysteroscopy, 46 of 105 patients (43.8%) with single or multiple leiomyomas of significant sizes diagnosed laparoscopically were noted to have pathology within the uterine cavity. Ten of 11 patients (90.9%) found to have ovarian cysts underwent hysteroscopy. Four (40%) had uterine abnormalities; the most common was cervical stenosis. Pelvic adhesions were found in 118 patients (21.6%). Eighty-nine underwent hysteroscopy, and 24 (27%) had intrauterine abnormalities. Ninety-six patients (17.5%) who underwent laparoscopic evaluation had endometriosis and pelvic adhesions. Ninety-three of these underwent hysteroscopy, and abnormalities were noted in 26 (28.0%). In eight women (1.5%) no abnormality was found at laparoscopy. Two underwent hysteroscopy, and no abnormality was noted in either woman. Hysteroscopy provides useful, adjunctive information and may improve the diagnosis and treatment of chronic pelvic pain.

Occupational portrayals on television: children's role schemata, career aspirations, and perceptions of reality.

UNLABELLED: Do children's schemata for occupations they observe in real life differ from those they see on TV? 177 second- and fifth-graders were assigned to conditions in a 2 (real-life or on TV) x 2 (police officer or nurse) design. They answered open-ended questions about what police officers or nurses do (in real life or on TV) and rated the typicality of various job activities. Their schematic knowledge about TV and real occupations was clearly differentiated. TV versions entailed more glamour, higher income, more stereotypes, and more dramatic events without negative consequences. Real-life occupations entailed more effort, status, and excitement. Older children differentiated slightly more clearly than younger ones. Children who perceived television as factual and realistic had real-world schemata similar to TV images. Children who were heavy viewers and perceived television as realistic were most likely to aspire to jobs shown on TV. CONCLUSION: children form separate schemata for social information acquired from TV and from real-world experience, but those who perceive television as socially realistic are apt to incorporate TV messages in their schemata and their aspirations.

[Asymptomatic sexually transmitted infections among HIV-tested persons].

We have prospectively determined the frequency of asymptomatic sexually transmitted diseases (STD) among patients seeking an HIV-test. In 246 patients, we observed 32 cases (13%) of asymptomatic STD, predominantly infections caused by Chlamydia trachomatis or human Papillomavirus. STD screening is of significance among patients seeking an HIV-test.

Steroid hormone regulation and tissue-specific expression of the human GnRH gene in cell culture and transgenic animals.

In order to study the molecular mechanisms involved in the control of GnRH gene expression, the human GnRH gene was cloned and characterized. The gene was expressed in cells obtained from CNS tumors in transgenic mice generated utilizing 1131 bp of 5' flanking GnRH DNA fused to the simian virus 40 large T antigen. We have shown a stimulatory estrogen response element in the human GnRH gene by transient transfection studies. DNase I footprinting and an avidinbiotin DNA binding assay demonstrated that the human GnRH gene bound ER. The GN cell line was found to have nuclear ERs utilizing an 125I estradiol binding study and by in situ hybridization histochemistry. In order to study GnRH expression in vivo, either 5000 or 484 bp of GnRH flanking DNA was fused to the luciferase (Luc) reporter gene, and transgenic mice generated. Expression in the transgenic animals was found in the hypothalamus of animals bearing the -5000Luc transgene, but not in animals bearing the -484Luc transgene. The transgenic mice expressing the -5000Luc gene were gonadectomized resulting in a 20-30% increase in hypothalamic Luc expression in the males and a 65% increase in females, while mice who were gonadectomized and replaced with testosterone (males) or E2 (females) showed a 50% decrease in Luc expression over control levels. Thus, these studies present in vitro evidence of E2 modulation of GnRH gene expression and an in vivo model in which sensitive studies of GnRH regulation and expression can be performed.

Does rapid eye movement desensitization facilitate emotional processing?

Recent years have seen considerable interest in rapid eye movement desensitization (REMD), a novel procedure for the treatment of traumatic memories and related conditions. REM is usually administered as a component of a broader therapeutic procedure, now termed eye movement desensitization and reprocessing (EMDR). On the basis of previous and largely uncontrolled work, it is not clear to what degree therapeutic gains can be attributed exclusively to REMD. Following exposure to a contrived trauma, Ss were allocated to one of three conditions: REMD; slow eye movement desensitization (SEMD); and stationary-imagery (SI; i.e. no eye movement). Emotional processing was significantly impaired in the REMD group compared to the SEMD and SI groups. No significant differences were found between the SEMD and SI groups.

Ingress of water into zeolite 4A powder plugs.

One dimensional profiles of the concentration of water absorbed from vapour diffusing into compacted type 4A zeolite powder have been obtained by broadline NMR imaging. After an induction period of approximately 6 h, a region of full hydration advances linearly with time into the zeolite plug. This behaviour is typical of Case II diffusion. A simple numerical simulation gives good agreement with the experimental results.

The AIDS epidemic among Scandinavian women: 1980-1990.

OBJECTIVE: To describe trends and patterns in the AIDS epidemic among Scandinavian women with AIDS. SUBJECTS AND METHODS: All women with AIDS reported to national surveillance units in Denmark, Norway and Sweden in 1980-1990 were included for analyses. RESULTS: The number of heterosexually infected female AIDS cases increased over time. AIDS-defining diseases varied with transmission categories, a variation similar to that found among heterosexual Danish male AIDS cases. Heterosexually infected women were more frequently diagnosed with Pneumocystis carinii pneumonia than with oesophagus candidiasis compared with intravenous drug using women. Twenty-five out of 56 heterosexually infected women reported having a male partner who was bisexual or from a Pattern II country, while one in four did not recognize any risk in their sex partner(s). Survival time increased between 1980 and 1990 and did not differ from survival in male AIDS cases. In a proportional hazards model, age, year of diagnosis and the duration of known HIV-positivity before development of AIDS had an independent impact on survival. The number of women known to be HIV-positive for more than 1 year before diagnosis of AIDS increased over time, although the number of women tested for HIV close to the development of AIDS was especially high among heterosexually infected women. CONCLUSION: Increasing numbers of heterosexually infected women are being diagnosed with AIDS in Scandinavia.

IgG subclass-associated differences in anti-schistosomal antibody specificity.

Consecutive sera from before and after treatment were collected from 23 patients with a Schistosoma mansoni infection, seven of whom had an early infection. All sera were analysed for IgG1, IgG3 and IgG4 antibody activity against three peptides from the protein Sm 28 GST (24-43, 115-131 and 140-153 aa). In addition, sera from 14 patients, four with an early infection and 10 patients with a chronic infection, were analysed for IgG and IgA antibody activity using seven peptides derived from the protein Sm 28 GST. This molecule has previously demonstrated protective activity against infection in various experimental models. The results are indicative of a subclass-related epitope specificity of the antibodies. Moreover, reactivity to one of the peptides (158-175 aa) was significantly associated with a chronic infectious status.

Efficacy of tumor necrosis factor alpha and eicosanoid inhibitors in experimental models of neonatal sepsis.

The potential role of tumor necrosis factor alpha (TNF alpha) and eicosanoids in the pathogenesis of experimental neonatal sepsis models was investigated. Lethality was induced in neonatal rats by administration of heat killed group B streptococci (GBS, 7 mg kg-1 intracardially) or Salmonella enteritidis endotoxin (0.35 mg kg-1 intracardially). The relative efficacy of six compounds with putative TNF alpha and eicosanoid inhibitory actions were tested. These were: ibuprofen (3 and 20 mg kg-1), a cyclo-oxygenase inhibitor; CGS85515 (30 mg kg-1), a lipoxygenase inhibitor; LY203647 (30 mg kg-1), a leukotriene D4 receptor antagonist; pentoxifylline (10, 50 and 100 mg kg-1), a TNF inhibitor; cloricromene (2 and 10 mg kg-1), a thromboxane A2 synthetase inhibitor with TNF alpha inhibitory actions; and SKF86002 (2.5, 5, 10 and 20 mg kg-1), a dual cyclo-oxygenase/lipoxygenase inhibitor with TNF alpha inhibitory activity. Pentoxifylline, cloricromene and SKF86002, when given intraperitoneally 2 h before challenge, produced 45, 52 and 61% reductions, respectively, in plasma levels of TNF alpha at 2.5 h post-injection with killed GBS (P < 0.05). On the contrary, pretreatment with ibuprofen, CGS85515 or LY203647 did not significantly affect TNF alpha levels. All compounds significantly attenuated the lethality by killed GBS and S. enteritidis endotoxin. These data suggest that TNF alpha and eicosanoids contribute to the pathogenesis of shock induced by killed GBS and endotoxemia.

Danish AIDS patients 1988-1993: a recent decline in Pneumocystis carinii pneumonia as AIDS-defining disease related to the period of known HIV positivity.

The frequency of PCP among adult Danish AIDS patients notified in 1988-93 was higher among patients tested HIV-positive less than 4 months prior to AIDS than among those known to be positive for > 1 year. Among the latter, the proportion with PCP decreased significantly over the period, from 45.3% in 1988 to 22.0% in 1993, while no such trend was found among patients tested positive for HIV less than 4 months before AIDS was diagnosed. The incidence of PCP as an AIDS-defining disease has decreased, most likely due to the use of PCP prophylaxis.

Mandatory anonymous HIV surveillance in Denmark: the first results of a new system.

OBJECTIVES: This paper describes the principles and first results of the newly implemented anonymous mandatory human immunodeficiency virus (HIV) reporting system in Denmark. METHODS: The system is based on a serially numbered form that is circulated among the laboratories, the physicians, and the national surveillance unit. All laboratories doing confirmatory tests for HIV antibodies must send a report form along with any positive test results. Before forwarding the form, the laboratory is to fill in the top part with the name and address of the requesting physician and send the back copy to the surveillance unit. The physicians are mandated by law to fill in the form with data on the patient and to keep two copies for their own files before sending the original to the surveillance unit. RESULTS: After a revision of the system, a response rate of 95% was obtained. CONCLUSIONS: We have established an anonymous mandatory HIV surveillance system in Denmark that enables routine evaluation of the completeness of reporting and nonresponding physicians to be reminded of their duty to report. Also, the physicians can act as mediators between patients and researchers; therefore, nested studies can be done without breaking the anonymity of the patient.
