Banning tobacco sponsorship: replacing tobacco with health messages and creating health-promoting environments

OBJECTIVE: To evaluate the replacement of Western Australian tobacco sponsorship with health promotion sponsorship by the Western Australian Health Promotion Foundation (known as "Healthway"), following the Tobacco Control Act 1990. DESIGN: Process measures of performance were collected from 25 tobacco replacement projects (sponsorship by Healthway of sport, racing, and arts groups previously supported by tobacco companies) and 727 other health sponsorship projects, that is, new sponsorship provided by Healthway to these groups. Cross-sectional survey data were obtained from 917 respondents at tobacco replacement and 2352 at other sponsorship venues. SETTING: Sport, racing, and arts venues sponsored by the Western Australian Health Promotion Foundation (Healthway) in 1991-95. MAIN OUTCOME MEASURES: Population reach, occasions of media publicity, healthy structural changes, cognitive/attitudinal impact of health messages, and the prevalence of five health-risk behaviours. RESULTS: Tobacco replacement and other sponsorship projects achieved comparable performance in publicity for health messages and in healthy structural change, but replacement projects achieved a fourfold higher level of direct population reach for a given amount of funding. Structural change towards a smoke-free environment occurred more often in tobacco replacement projects and a permanent smoke-free policy was achieved in 47% of projects, compared with 15% in other sponsorship projects. The prevalence ratio of current smoking at tobacco replacement venues was 1.86 (95% confidence interval 1.62 to 2.04) relative to other sponsorship venues. There was evidence of higher cognitive resistance to health messages at venues previously sponsored by tobacco companies. CONCLUSIONS: A comprehensive ban on tobacco sponsorship linked to health promotion activities funded by tobacco tax delivers potential public health benefits that exceed those achieved by prohibition of tobacco sponsorship alone. Tobacco replacement venues offer opportunities for environmental modification, promotion of anti-smoking messages, and targeting groups that are hard to reach.


     

Red meat (beef and sheep) products for an ageing population: a review

The global population is becoming older, and still, this cohort considers red meat (beef and sheep meat) as an important staple in their diet. It is understood that the requirements from these red meats will vary as a person ages, often because of associated physiological changes; nutrition and health concerns; and reduced sensorial capacities. This creates an imperative to develop red meat products that appeal and satisfy the demands of elderly people. Here, we have reviewed current literature with the aim to comprehend the elderly consumer market, their demands for nutritive and quality traits, and their requirements for safe and convenient red meat (beef and sheep) products. Based on these studies, it was apparent that these specifications may be delivered using available knowledge of intrinsic and extrinsic influences on red meat if considered within the context of elderly customers, that is, to deliver upon elderly people’s requirements for conventional red meat products which are inexpensive, of consistent and perceivable high quality, and quell any associated health concerns for the consumer.     

Electron spin resonance study of chromium(V) formation and decomposition by basalt-inhabiting bacteria

Bacterial reduction of Cr(VI) to Cr(III) compounds may produce reactive intermediates Cr(V) and Cr(IV), which can affect the mobility and toxicity of chromium in environments. To address this important subject, we conducted an electron spin resonance (ESR) study to understand the kinetics of the formation and decomposition of Cr(V) during Cr(VI) reduction by different gram-positive Cr(VI)-tolerant bacteria, which were isolated from polluted basalts from the United States of America and the Republic of Georgia. Results from our batch experiments show that during Cr(VI) reduction, the macromolecules at the cell wall of these bacteria could act as an electron donor to Cr(VI) to form a stable square-pyramidal Cr(V) complexes, which were reduced further probably via a one-electron transfer pathway to form Cr(IV) and Cr(III) compounds. The Cr(V) peak at the ESR spectrum possessed superhyperfine splitting characteristic of the Cr(V) complexes with diol-containing molecules. It appears that the kinetics of Cr(V) formation and decomposition depended on the bacterial growth phase and on the species. Both formation and decomposition of Cr(V) occurred more quickly when Cr(VI) was added at the exponential phase. In comparison with other gram-positive bacteria from the republic of Georgia, the formation and decomposition of Cr(V) in Arthrobacter species from the Unites States was significantly slower.     

Evaluation of gastrointestinal solubilization of petroleum hydrocarbon residues in soil using an in vitro physiologically based model

Petroleum hydrocarbon residues in weathered soils may pose risks to humans through the ingestion pathway. To understand the factors controlling their gastrointestinal (GI) absorption, a newly developed experimental extraction protocol was used to model the GI solubility of total petroleum hydrocarbon (TPH) residues in highly weathered soils from different sites. The GI solubility of TPH residues was significantly higher for soil contaminated with diesel than with crude oil. Compared to the solubility of TPH residues during fasted state,the solubility of TPH residues during fat digestion was much greater. Diesel solubility increased from an average of 8% during the "gallbladder empty" phase of fasting (and less than 0.2% during the otherfasting phase) to an average of 16% during fat digestion. For crude oil, the solubility increased from an average of 1.2% during the gallbladder empty phase of fasting (and undetectable during the other fasting phase) to an average of 4.5% during fat digestion. Increasing the concentration of bile salts also increased GI solubility. GI solubility was reduced by soil organic carbon but enhanced by the TPH content.     

A classification of controlled interpersonal affect regulation strategies.

Controlled interpersonal affect regulation refers to the deliberate regulation of someone else’s affect. Building on existing research concerning this everyday process, the authors describe the development of a theoretical classification scheme that distinguishes between the types of strategy used to achieve interpersonal affect regulation. To test the theoretical classification, the authors generated a corpus of 378 distinct strategies using self-report questionnaires and diaries completed by student and working samples. Twenty participants then performed a card-sort of the strategies. Hierarchical cluster analysis was used to determine how well the theoretical classification represented spontaneous understandings of controlled interpersonal affect regulation. The final classification primarily distinguished between strategies used to improve versus those used to worsen others’ affect, and between strategies that engaged the target in a situation or affective state versus relationship-oriented strategies. The classification provides a meaningful basis for organizing existing research and making future conceptual and empirical distinctions.

A prospective algorithm for the management of air leaks after pulmonary resection

BACKGROUND: Air leaks (ALs) are a common complication after pulmonary resection, yet there is no consensus on their management. METHODS: An algorithm for the management of chest tubes (CT) and ALs was applied prospectively to 101 consecutive patients who underwent elective pulmonary resection. Air leaks were graded daily as forced expiratory only, expiratory only, inspiratory only, or continuous. All CTs were kept on 20 cm of suction until postoperative day 2 and were then converted to water seal. On postoperative day 3, if both a pneumothorax and AL were present, the CT was placed to 10 cm H2O of suction. If a pneumothorax was present without an AL, the CT was returned to 20 cm H2O of suction. Air leaks that persisted after postoperative day 7 were treated with talc slurry. RESULTS: There were 101 patients (67 men); on postoperative day 1, 26 had ALs and all were expiratory only. Univariable analysis showed a low ratio of forced expiratory volume in 1 second to forced vital capacity (FEV1/FVC) (p = 0.005), increased age (p = 0.007), increased ratio of residual volume to total lung capacity (RV/TLC) (p = 0.04), increased RV (p = 0.02), and an increased functional residual capacity (FRC) (p = 0.02) to predict the presence of an AL on postoperative day 1. By postoperative day 2, 22 patients had expiratory ALs. After 12 hours of water seal, 13 of the 22 patients' ALs had stopped, and 3 more sealed by the morning of postoperative day 3. However, 2 of the 6 patients whose ALs continued experienced a pneumothorax. Five of the 6 patients with ALs on postoperative day 4 still had ALs on postoperative day 7, and all were treated by talc slurry through the CT. All ALs resolved within 24 hours after talc slurry. CONCLUSIONS: Most ALs after pulmonary resection are expiratory only. A low FEV1/FVC ratio, increased age, increased RV/TLC ratio, increased RV, and an increased FRC were predictors of having an ALs on postoperative day 1. Conversion from suction to water seal is an effective way of sealing expiratory AL, and pneumothorax is rare. If an expiratory AL does not stop by postoperative day 4 it will probably persist until postoperative day 7, and talc slurry may be an effective treatment.     

Alpha 2-agonist agents: a review for CRNAs

Over 300 clonidine-related research articles have been prominently featured in anesthesia journals over the last 4 to 5 years. Nurse anesthetists may already find themselves administering alpha 2-adrenergic agents to help control hypertension; however, in the future their use as anesthetic adjuncts to control pain may also become important. This article reviews the alpha 2-adrenergic (A2) receptor and one of its agonist agents, clonidine.     

Validation of low-dose dobutamine magnetic resonance imaging for assessment of myocardial viability after infarction by serial imaging

Cine magnetic resonance imaging with low-dose dobutamine stimulation allows prediction of viability after infarction with an accuracy of 80%. In akinetic segments, however, viability tends to be underestimated.     

Getting "stuck" in the past: temporal orientation and coping with trauma

The relations between temporal orientation and long-term psychological distress were studied cross-sectionally and longitudinally in 3 samples of traumatized individuals: adult victims of childhood incest, Vietnam War veterans, and residents of 2 southern California communities devastated by fire. Results indicated that a past temporal orientation--focusing attention on prior life experiences--was associated with elevated levels of distress long after the trauma had passed, even when controlling for the degree of rumination reported. Temporal disintegration at the time of the trauma--whereby the present moment becomes isolated from the continuity of past and future time--was associated with a high degree of past temporal orientation over time and subsequent distress. Temporal disintegration was highest among individuals who had experienced the most severe loss, had previously experienced chronic trauma, and had had their identities threatened by their traumatic experience.     

Evidence for a critical role for IL-2 in CD40-mediated activation of naive B cells by primary CD4 T cells

The interaction of CD40 on B cells with the CD40 ligand (CD40L) on preactivated CD4 T cells is critical for the initiation of T-dependent Ab responses. It is believed that signals via CD40 synergize with cytokines (e.g., IL-4 and IL-5) to drive B cell activation. However, primary T cells preactivated via CD3 alone cannot induce B cell proliferation; we have shown previously that costimulation of T cells via CD3 and CD28 stabilizes the expression of the CD40L, which we propose contributes to their capacity to act as competent helper-effector cells. Here we show that an additional, critical reason why CD3-stimulated CD40L-bearing T cells are incompetent helper cells is because they secrete insufficient IL-2. In contrast, CD28/CD3-activated T cells induce B cells to become IL-2 responsive via a combination of CD40L and IL-2-mediated signals, and these two stimuli subsequently drive B cell proliferation and IgM secretion. We therefore propose that T cells must first encounter Ag in conjunction with CD80/86 on APCs. This leads to the stable expression of CD40L and maximal secretion of IL-2, which together render primary T cells competent to activate B cells in an IL-2-dependent fashion.
