Effects of gestational alcohol exposure on the fatty acid composition of umbilical cord serum in humans.

This study examined the effects of maternal periconceptional alcohol intake on polyunsaturated fatty acid (PUFA) concentrations in human neonates. The area percentage of each fatty acid in cord blood serum from 12 infants born to control women (who consumed <2 mL absolute ethanol/d) was compared with that of 9 infants born to women whose periconceptional alcohol intake averaged > or = 30mL absolute ethanol/d. Periconceptional alcohol use was associated with a 30% increase in the proportion of docosahexaenoic acid (22:6n-3) in cord blood (3.0% of total lipid in control infants compared with 3.9% in alcohol-exposed infants; P < 0.01). The rise in the proportion of 22:6n-3 was responsible for increases in the ratio of n-3 to n-6 fatty acids and the ratio of long-chain n-3 to n-6 fatty acids (P < 0.055). Examination of the lipid-class fatty acid profile indicated that serum lipid alterations were localized to the cholesterol esters; 22:6n-3 in the cholesterol esters of alcohol-exposed infants increased 54% (P < 0.011) and arachidonic acid increased 55% (P < 0. 005). The relative fatty acyl composition of maternal serum showed a significant increase in 18:0 fatty acids in the alcohol-exposed group (25%, P < 0.005) but there were no changes in the other fatty acids. The increase in the proportion of 22:6n-3 was unexpected but is consistent with the hypothesis that this essential lipid may be conserved selectively. These results imply that the lifelong neurobehavioral and sensory dysfunction in fetal alcohol syndrome and other alcohol-related neurodevelopmental disorders may be due in part to PUFA dysregulation.

Well-differentiated villoglandular adenocarcinoma of the uterine cervix: oncogene/tumor suppressor gene alterations and human papillomavirus genotyping.

Twelve well-differentiated villoglandular adenocarcinomas (WDVAs) of the uterine cervix were retrospectively analyzed for the presence and specific genotype of human papillomavirus (HPV), tumor suppressor loss (p53, MCC, APC, BRCA1), cancer gene mutation (K-ras-2, exons 1 and 2, p53 exons 5 to 8), and oncogene amplification (c-erbB-2/HER-2/neu, int-2). Tissue for genetic evaluation was obtained by microdissection, using 4-micron-thick histology sections of archival, formalin-fixed, paraffin-embedded specimens. Genotyping involved nucleic acid amplification and DNA sequencing with gene-specific oligonucleotides and L1 region consensus primers for common strains of HPV. Point mutation and HPV strain determination were accomplished by DNA sequence analysis. Tumor suppressor gene loss and oncogene amplification were performed by allelic imbalance analysis in informative subjects based on DNA sequence and microsatellite-length polymorphisms. HPV was present in all tumors and consisted of type 16 (n = 5, 42%) and type 18 (n = 7, 58%) strains, which have been closely associated with cervical neoplasia. K-ras-2 and p53 genes did not manifest point mutational damage. There was no evidence of oncogene amplification or tumor suppressor gene loss. The presence of HPV in all 12 tumors supports the role of HPV infection in the molecular pathogenesis of this uncommon neoplasm. The absence of associated oncogene or tumor suppressor gene damage is consistent with indolent biological behavior and the favorable prognosis of this unusual tumor.

Special feature for the Olympics: effects of exercise on the immune system: exercise-induced modulation of macrophage function.

Macrophages are important effector cells involved in phagocytosis, microbial killing and antitumour activity. Macrophages also display accessory cell function, in that they can present antigen to foster the development of T lymphocyte-mediated immunity. Recent work, including studies from this group, has demonstrated that acute and chronic exercise can affect many facets of macrophage biology. Manifestation of these effects depends on exercise intensity and duration, the function measured, the timing of measurement in relation to exercise and the concentration of the macrophage-activating stimulus. Exercise has potent stimulatory effects on phagocytosis, antitumour activity, reactive oxygen and nitrogen metabolism, and chemotaxis. Indeed, it has been shown that exercise training can increase macrophage antitumour activity in mice of different ages. However, not all functions are enhanced by exercise. Exercise-induced reductions in macrophage MHC II expression and antigen-presentation capacity have been documented. These findings bring up the possibility that exercise, and perhaps other stressors, activate macrophages for effector functions while downregulating accessory cell functions. To a large extent, the mechanisms responsible for the exercise-induced changes in macrophage function remain unknown, but may depend on exercise-induced changes in neuroendocrine factors. Future studies need to explore the effects in a mechanistic way and provide documentation as to their physiological significance.

A national census of ambulance response times to emergency calls in Ireland.

BACKGROUND: Equity of access to appropriate pre-hospital emergency care is a core principle underlying an effective ambulance service. Care must be provided within a timeframe in which it is likely to be effective. A national census of response times to emergency and urgent calls in statutory ambulance services in Ireland was undertaken to assess current service provision. METHODS: A prospective census of response times to all emergency and urgent calls was carried out in the nine ambulance services in the country over a period of one week. The times for call receipt, activation, arrival at and departure from scene and arrival at hospital were analysed. Crew type, location of call and distance from ambulance base were detailed. The type of incident leading to the call was recorded but no further clinical information was gathered. Results-2426 emergency calls were received by the services during the week. Fourteen per cent took five minutes or longer to activate (range 5-33%). Thirty eight per cent of emergencies received a response within nine minutes (range 10-47%). Only 4.5% of emergency calls originating greater than five miles from an ambulance station were responded to within nine minutes (range 0-10%). Median patient care times for "on call" crews were three times longer than "on duty" crews. CONCLUSION: Without prioritized use of available resources, inappropriately delayed responses to critical incidents will continue. Recommendations are made to improve the effectiveness of emergency medical service utilisation.

Needs and opportunities for improving the health, safety, and productivity of medical research facilities.

Medical research facilities, indeed all the nation's constructed facilities, must be designed, operated, and maintained in a manner that supports the health, safety, and productivity of the occupants. The National Construction Goals, established by the National Science and Technology Council, envision substantial improvements in occupant health and worker productivity. The existing research and best practices case studies support this conclusion, but too frequently building industry professionals lack the knowledge to design, construct, operate, and maintain facilities at these optimum levels. There is a need for more research and more collaborative efforts between medical and facilities engineering researchers and practitioners in order to attain the National Construction Goals. Such collaborative efforts will simultaneously support attainment of the National Health Goals. This article is the summary report of the Healthy Buildings Committee for the Leadership Conference: Biomedical Facilities and the Environment sponsored by the National Institutes of Health, the National Association of Physicians for the Environment, and the Association of Higher Education Facilities Officers on 1--2 November 1999 in Bethesda, Maryland, USA.

Efficacy of potential chemopreventive agents on rat colon aberrant crypt formation and progression.

We assessed the effects of 78 potential chemopreventive agents in the F344 rat using two assays in which the inhibition of carcinogen-induced aberrant crypt foci (ACF) in the colon was the measure of efficacy. In both assays ACF were induced by the carcinogen azoxymethane (AOM) in F344 rats by two sequential weekly injections at a dose of 15 mg/kg. Two weeks after the last AOM injection, animals were evaluated for the number of aberrant crypts detected in methylene blue stained whole mounts of rat colon. In the initiation phase protocol agents were given during the period of AOM administration, whereas in the post-initiation assay the chemopreventive agent was introduced during the last 4 weeks of an 8 week assay, a time when ACF had progressed to multiple crypt clusters. The agents were derived from a priority listing based on reports of chemopreventive activity in the literature and/or efficacy data from in vitro models of carcinogenesis. During the initiation phase carboxyl amidoimidazole, p-chlorphenylacetate, chlorpheniramine maleate, D609, diclofenac, etoperidone, eicosatetraynoic acid, farnesol, ferulic acid, lycopene, meclizine, methionine, phenylhexylisothiocyanate, phenylbutyrate, piroxicam, 9-cis-retinoic acid, S-allylcysteine, taurine, tetracycline and verapamil were strong inhibitors of ACF. During the post-initiation phase aspirin, calcium glucarate, ketoprofen, piroxicam, 9-cis-retinoic acid, retinol and rutin inhibited the outgrowth of ACF into multiple crypt clusters. Based on these data, certain phytochemicals, antihistamines, non-steroidal anti-inflammatory drugs and retinoids show unique preclinical promise for chemoprevention of colon cancer, with the latter two drug classes particularly effective in the post-initiation phase of carcinogenesis.

FILM (5-fluorouracil, ifosfamide, leucovorin and mitomycin C), an alternative chemotherapy regimen suitable for the treatment of advanced breast cancer in the 'out-patient' setting.

FILM, a combination of 5-fluorouracil (5-FU) 750 mg/m(2), ifosfamide 1 g/m(2), leucovorin 200 mg/m(2) and mitomycin C 6 mg/m(2) (alternate cycles), was administered to 24 chemo-naive patients with inoperable disease, locally advanced or metastatic. Up to 6 x 3-weekly cycles of FILM were administered on an out-patient basis. Responses included 8 patients in complete remission (CR) and 12 showing a partial response (PR) (83%). Following analysis of these results, the FILM regimen was introduced as a standard out-patient protocol at the North Middlesex Hospital, United Kingdom. A further 66 patients have been treated in this setting. Retrospective analysis of these data confirm the trial results and allow conclusions regarding tolerability, toxicity, duration of response and survival to be drawn from a total cohort of 90 patients. A total of 524 cycles have been administered. Nineteen cycles (4%) were delayed owing to slow recovery of white blood cells (WBC), but no dose reductions were necessary. Five blood transfusions were required for anaemia. The most frequent non-haematological toxicities included nausea, vomiting and fatigue. Of 80 patients treated for inoperable or locally advanced disease, 56 (70%) remain in remission, and 69 (86%) remain alive after 5 years.

Clinical options for women at high risk for breast cancer.

Women at hereditary risk of breast cancer face a difficult clinical decision. Each of the options available to them has unique advantages and disadvantages that are summarized in Table 9. Many components enter a high-risk woman's decision: her objective risk of breast cancer; clinical features, such as the consistency of breast tissue and resultant ease of examination; breast density on mammography; personal characteristics, including her experience with cancer within her family; her role and [table: see text] responsibilities within her own nuclear family; her values and goals; her experiences with the medical system; and her subjective assessment of risk. It is generally believed that women significantly overestimate their risk of breast cancer. Thus, it is vital that a woman at risk have access to a genetic counselor who can provide accurate assessment of her risk. Women should be encouraged to take time to understand their risk level and the advantages and disadvantages of the options before them.

Cold-temperature plastic resin embedding of liver for DNA- and RNA-based genotyping.

The standard practice of tissue fixation in 10% formalin followed by embedding in paraffin wax preserves cellular morphology at the expense of availability and quality of DNA and RNA. The negative effect on cellular constituents results from a combination of extensive cross-linking and strand scission of DNA, RNA, and proteins induced by formaldehyde as well as RNA loss secondary to ubiquitous RNase activity and negative effects of high temperature exposure during paraffin melting, microscopic section collection, and tissue adherence to glass slides. An effective strategy to correlate cellular phenotype with molecular genotype involves microdissection of tissue sections based on specific histopathological features followed by genotyping of minute representative samples for specific underlying molecular alterations. Currently, this approach is limited to short-length polymerase chain reaction amplification (<250 bp) of DNA, due to the negative effects of standard tissue fixation and processing. To overcome this obstacle and permit both cellular morphology and nucleic acid content to be preserved to the fullest extent, we instituted a system of cold-temperature plastic resin embedding based on the use of the water-miscible methyl methacrylate polymer known as Immunobed (Polysciences, Warminster, PA). The system is simple, easy to adapt to clinical practice, and cost-effective. Immunobed tissue sections demonstrate a cellular appearance equivalent or even superior to that of standard tissue sections. Moreover, thin sectioning (0.5-1.0 microm thickness) renders ultrastructural evaluation feasible on plastic-embedded blocks. Tissue microdissection is readily performed, yielding high levels of long DNA and RNA for genomic and transcription-based correlative molecular analysis. We recommend the use of Immunobed or similar products for use in molecular anatomical pathology.

Peroxisome proliferator-activated receptor gamma is induced during differentiation of colon epithelium cells.

Peroxisome proliferator-activated receptor gamma (PPARgamma), a fatty acid-activated nuclear receptor, is implicated in adipocyte differentiation and insulin sensitisation. In view of the association of dietary fat intake and bowel disease, the expression of PPARgamma in rodent and human intestine was studied. Expression of PPARgamma mRNA was examined by Northern blot hybridisation, RNase protection, and/or competitive RT-PCR assays, whereas PPARgamma protein levels were evaluated by immunoblotting and immunohistochemistry. PPARgamma mRNA and protein were abundantly expressed in colon relative to the small intestine both in rodents and in man. Interestingly, expression of PPARgamma was primarily localised in the more differentiated epithelial cells in the colon. The level of expression of PPARgamma in colon was similar to the levels seen in adipose tissue. Expression of PPARgamma increased from proximal to distal segments of the colon in man. In Caco-2 and HT-29 human adenocarcinoma cells, PPARgamma expression increased upon differentiation, consistent with PPARgamma being associated with a differentiated epithelial phenotype. High-level expression of PPARgamma was observed in the colon, but not in the small intestine, suggesting a potential role of this nuclear receptor in the colon.

The causes of patient dropout from penile self-injection therapy for impotence.

PURPOSE: Penile self-injection therapy, a second line treatment for erectile dysfunction, is the most efficacious means of reestablishing functional erections when first line therapies fail and the patient wants to avoid penile prosthesis implantation. Despite high efficacy rates, injection therapy has high dropout rates. To our knowledge studies to date analyzing patient attrition have reviewed small numbers of patients followed for only short periods. We elucidate the main reasons for patient dropout in a large penile self-injection program with long-term followup. MATERIALS AND METHODS: A questionnaire was mailed to 1,424 patients who completed the office training and home use phases of a penile self-injection program. RESULTS: The overall attrition rate was 31% of the 720 men who completed the questionnaire, with a mean followup of 38 months. The main reasons for dropout were cost of therapy, patient and partner problems with the concept of penile injection, lack of partner availability and spontaneous improvement in erections. Lack of efficacy of therapy was the primary reason for only 1 of 7 dropouts. Furthermore, adverse effects of penile injections (priapism, penile nodules, pain) appeared to be only minor contributors to dropout. CONCLUSIONS: To our knowledge this study is the largest published, single center cohort of patients treated with injection and followed for an analysis of dropout rates. Based on study data a reduction in dropout rates may be achieved by keeping the cost of therapy low, and ensuring patient and partner education as well as continued support throughout treatment.

Nuclear factor I regulates expression of the gene for phosphoenolpyruvate carboxykinase (GTP).

Nuclear factor-I (NFI) binds to the phosphoenolpyruvate carboxykinase (GTP) (PEPCK) gene promoter immediately 5' to the cAMP regulatory element (CRE). This suggests an interaction between NFI and factors that bind the CRE. Of the four NFI isoforms expressed in mammalian tissues, NFI-A and -B stimulate basal transcription from the PEPCK gene promoter in HepG2 cells, while NFI-C and -X are slightly inhibitory. All four NFI isoforms abrogate the 20-fold protein kinase Ac (PKAc)-mediated induction of transcription from the PEPCK gene promoter. Normal PKAc-mediated induction was noted when the CRE was moved 10 base pairs 3' of its original location. However if the CRE was moved 5 base pairs 3', placing it out of phase with the other elements in the promoter, or moved 5' to -285 (the P3(I) site in the promoter), some PKA-mediated stimulation was lost. The NFI-C isoform effectively inhibited PKAc induction regardless of the relative positions of the CRE and the NFI binding sites. NFI-C also abrogated cAMP regulatory element-binding protein (CREB)-induced activity of wild type and mutant PEPCK promoters. There was some cooperativity in the binding of CREB and NFI to their respective binding sites but this did not appear to be physiologically important.

Bronchodilator S-nitrosothiol deficiency in asthmatic respiratory failure.

BACKGROUND: Nitric oxide (NO) gas concentrations are high in the expired air of individuals with asthma, but not consistently so in the expired air of people with pneumonia. S-nitrosothiols are naturally occurring bronchodilators, the concentrations of which are raised in the airways of patients with pneumonia. Airway S-nitrosothiols have not been studied in asthma. METHODS: Tracheal S-nitrosothiol concentrations from eight asthmatic children in respiratory failure were compared with those of 21 children undergoing elective surgery. RESULTS: Mean S-nitrosothiol concentrations in asthmatic children were lower than in normal children (65 [SD 45] nmol/L vs 502 [SD 429] nmol/L) and did not vary with inspired oxygen concentration or airway thiol concentration. INTERPRETATION: Severe asthma is associated with low concentrations of airway S-nitrosothiols. This is the first reported deficiency of an endogenous bronchodilator in the human asthmatic airway lining fluid. We suggest that S-nitrosothiol metabolism may be a target for the development of new asthma therapies.

A tacrolimus-related immunosuppressant with reduced toxicity.

BACKGROUND: Tacrolimus (FK506) has potent immunosuppressive properties reflecting its ability to block the transcription of lymphokine genes in activated T cells through formation of a complex with FK506 binding protein-12, which inhibits the phosphatase activity of calcineurin. The clinical usefulness of tacrolimus is limited, however, by severe adverse effects, including neurotoxicity and nephrotoxicity. Although this toxicity, like immunosuppression, appears mechanistically related to the calcineurin inhibitory action of the drug, a large chemistry effort has been devoted to search for tacrolimus analogs with reduced toxicity but preserved immunosuppressive activity that might have enhanced therapeutic utility. METHODS: Here, we report on the identification of such an analog, which was synthetically derived from ascomycin (ASC), the C21 ethyl analog of tacrolimus, by introducing an indole group at the C32 position. The profile of biological activity of indolyl-ASC was characterized in rodent models of immunosuppression and toxicity. RESULTS: Indolyl-ASC was found to exhibit an immunosuppressive potency equivalent to that of tacrolimus in T-cell activation in vitro and in murine transplant models, even though indolyl-ASC bound about 10 times less to intracellular FK506 binding protein-12 than tacrolimus or ASC. Further evaluation of indolyl-ASC revealed that it is threefold less potent than tacrolimus in inducing hypothermia, a response that may reflect neurotoxicity, and in causing gastrointestinal transit alterations in mice. Moreover, indolyl-ASC was at least twofold less nephrotoxic than tacrolimus upon 3-week oral treatment in rats. CONCLUSIONS: Altogether, these data indicate a modest but definite improvement in the therapeutic index for indolyl-ASC compared with tacrolimus in rodent models.

Role of skeletal muscle in thiazolidinedione insulin sensitizer (PPARgamma agonist) action.

Thiazolidinedione (TZD) insulin sensitizers are specific agonists of peroxisome proliferator activated receptor (PPAR)gamma. However, their mechanism of action and the in vivo target tissue(s) that mediate insulin sensitization remain poorly defined. Although PPARgamma messenger RNA expression has been reported in skeletal muscle, the expression of PPARgamma within myocytes in intact muscle tissue has not been examined. An antipeptide PPARgamma antibody was generated; immunohistochemistry was then used to demonstrate that PPARgamma is present within nuclei of myocytes [in both skeletal (white and red fibers) and cardiac tissue (rodent and human)]. The effect of insulin sensitizer treatment on muscle insulin action was studied using ob/ob mice after 4 days dosing with a potent (6 nM PPARgamma Kd) TZD (10 mg/kg x day). 2-deoxyglucose (2-DOG) uptake was then assessed in freshly isolated soleus muscles from lean vs. ob/ob vs. TZD-treated ob/ob mice. In lean mouse muscles, 2-DOG uptake was stimulated by 82%, 95%, 165% (with 25, 100, 2000 microU/ml insulin); muscles from ob/ob were severely insulin resistant (<80% stimulation with 2000 microU/ml insulin). Muscles from TZD-treated ob/ob displayed a normal insulin response with 100 (71%) or 2000 (158%) microU/ml insulin. Additional studies were performed using ZDF rats treated with/without TZD for 7 days. In vivo 2-DOG glucose uptake into soleus, gastrocnemius, and diaphragm muscles was measured during euglycemic-hyperinsulinemic clamp. Compared with lean rats, muscle 2-DOG uptake in ZDF was reduced by 52% (soleus) or 71% (diaphragm). Partial (40-60%) normalization of the reduced 2-DOG uptake was evident in TZD-treated ZDF rats. In contrast to the effect of in vivo treatment on muscle insulin action, preincubation of isolated soleus muscles from naive lean or ob/ob mice for 5 h with 100 nM TZD did not affect insulin-stimulated 2-DOG uptake. We conclude: 1) PPARgamma is expressed in myocytes within skeletal and cardiac muscle. 2) In vivo activation of PPARgamma by treatment of insulin-resistant mice/rats with a potent TZD corrects impaired muscle insulin action. 3) The lack of a direct effect on muscle after 5 h in vitro TZD incubation suggests that changes in insulin action may require a longer duration of PPARgamma activation or that improved muscle insulin sensitivity may result from an indirect in vivo effect of PPARgamma activation (e.g. changes in systemic lipid metabolism).

Devolving authority for health care in Canada's provinces: 3. Motivations, attitudes and approaches of board members.

OBJECTIVE: To obtain information from the members of the boards of devolved health care authorities on their motivations, attitudes and approaches, to evaluate their relative orientations to the expectations of provincial governments, local providers and community members, and to evaluate the influence of members' being employees in health care or social services and being willing to stand for election. DESIGN: Mail survey conducted in cooperation with the devolved authorities during the summer of 1995. SETTING: Three provinces (Alberta, Saskatchewan and Prince Edward Island) with established boards and 2 provinces (British Columbia and Nova Scotia) with immature boards. PARTICIPANTS: All 791 members of the boards of devolved authorities in the 5 provinces, of whom 514 (65%) responded. OUTCOME MEASURES: Respondents' declared motivations, levels of confidence in board performance and attitudes toward accountability; differences between members who were willing to run for election to boards and others and differences between members who were employees in health care or social services and others. RESULTS: The main motivations of board members were an interest in health care and a desire to be part of decision-making and their main concern was inadequacy of data for decision-making. Almost all (93%) felt that they made good decisions, and 69% thought that they made better decisions than those previously made by the provincial government. Most (72%) felt that they were accountable to all of the local citizens, although nearly 30% stated that they represented the interests of a specific geographic area or group. Attitudes toward their provincial governments were polarized, with half agreeing and half disagreeing that provincial rules restrict the board members. The board members who were employed in health care and social services and those who were willing to stand for election did not differ substantially from their counterparts, although potential electoral candidates were less likely than others to feel accountable to provincial-level constituencies (such as taxpayers and the minister of health) and more likely to represent the interests of a specific geographic area or group. Only a modest number of differences were found among members from different provinces. CONCLUSIONS: Board members' strong feelings of accountability to and representation of local citizens could counteract the structural influences leading board members to favour the interests of provincial governments and providers.

Devolving authority for health care in Canada's provinces: 2. Backgrounds, resources and activities of board members.

OBJECTIVE: To obtain information from the members of the boards of devolved health care authorities and evaluate their orientations in meeting the expectations of provincial governments, local providers and community members. DESIGN: Mail survey, conducted in cooperation with the devolved authorities, in the summer of 1995. SETTING: Three provinces (Alberta, Saskatchewan and Prince Edward Island) with established boards and 2 (British Columbia and Nova Scotia) with immature boards. PARTICIPANTS: All 791 members of boards of devolved authorities in the 5 provinces, of whom 514 (65%) responded. OUTCOME MEASURES: Sociodemographic background, training, experience and activities of board members as well as their use of information. RESULTS: There were systematic differences between established and immature boards in regard to training, information use and actual and desired activities. Members spent 35 hours per month, on average, on work for their board. Members were largely middle-aged, well educated and well off. Only 36% were employed full time. Nine out of 10 had previous experience on boards, more often in health care than in social services. They were least pleased with their training in setting priorities and assessing health care needs and most pleased with their training in participating effectively in meetings and understanding their roles and responsibilities. The information for decision-making most available to them was information on service costs (68% said it was available "most of the time" or "always") and utilization (64%); the least available information was that on key informants' opinions (47%), service benefits (37%) and citizens' preferences (28%). Board activity was dominated by setting priorities and assessing needs, secondarily occupied with ensuring the effectiveness and efficiency of services and allocating funds, and least concerned with delivering services and raising revenue. The match between activities desired by members and actual activities was significantly poorer for members of immature boards than for those of established boards. CONCLUSIONS: The responses concerning these structural variables suggest that board members are most likely to meet the expectations of provincial governments. Fewer appear well equipped to accommodate the views of their providers and even fewer to incorporate the perspectives of their community.
