Hand disinfection: a comparison of various agents in laboratory and ward studies

The efficacy of 14 handwashing or disinfectant preparations was compared in laboratory tests on staff volunteers. The test organism, Escherichia coli, was applied to the fingertips and log reductions (LR) were measured following treatment with the test agent and control preparations (70% isopropanol and non-medicated bar soap). Alcoholic preparations, particularly n-propanol and isopropanol were the most effective showing LRs of 3.1-3.8. Chlorhexidine (LR 2.9) and povidone-iodine detergent preparations were significantly more effective than non-medicated soap (LR 2.1), but triclosan products were not. In addition the residual effect of several of these formulations was assessed after 10 applications by comparing the survival of E. coli on the fingertips over a 32-min period. This number of handwashes compares favourably with those recorded during an 8 h nursing shift. Chlorhexidine-detergent consistently showed the best residual activity. Alcoholic formulations showed little or no residual effect. The survival studies show that on the whole gram-positive organisms (Staphylococcus aureus and Candida albicans) survive better on the skin than Gram-negative bacilli (GNB). However, it would seem that GNB which are considered to be residents (Acinetobacter calcoaceticus and Enterobacter spp.) survive much better than many other GNB (Pseudomonas aeruginosa, E. coli and Proteus vulgaris). The Klebsiella species varied in survival times. Random sampling of ward staff hands showed that contamination with S. aureus and GNB was greater in dermatological and general wards than in an isolation unit, where handwashing or disinfection was carried out after every patient contact. No cross-infection occurred in the isolation ward during periods of study in which 70% alcohol, chlorhexidine-detergent and non-medicated soap were used.     

Patient-reported recall of smoking cessation interventions from a health professional

Objective

To determine the prevalence and characteristics of current cigarette smokers who report receiving health care provider interventions (‘5A's’: ask, advise, assess, assist, arrange) for smoking cessation.

Methods

Data came from the 2009–2010 National Adult Tobacco Survey, a telephone survey of United States adults aged ≥ 18 years. Among current cigarette smokers who reported visiting a health professional in the past year (n = 16,542), estimates were calculated overall and by sex, age, race/ethnicity, education, income, health insurance coverage, and sexual orientation.

Results

Among smokers who visited a health professional (75.2%), 87.9% were asked if they used tobacco, 65.8% were advised to quit, and 42.6% were asked if they wanted to quit. Among those wanting to quit, 78.2% were offered assistance and 17.5% had follow-up arranged. Receipt of the ‘ask’ component was lower among males and uninsured individuals. Receipt of the ‘advise’ and ‘assess’ components was lower among those aged 18–24 and uninsured individuals. Receipt of the ‘assist’ component was lower among non-Hispanic blacks. No differences were observed for the ‘arrange’ component.

Conclusions

Many current smokers report receiving health care provider interventions for smoking cessation. Continued efforts to educate, encourage, and support all health professionals to provide effective, comprehensive tobacco cessation interventions to their patients may be beneficial.     

PCV16 Smoking Related Costs in the United States

Smoking is a high-risk behavior that affects the health and economic welfare of society. Thus, it is important to quantify the economic burden smoking places on social institutions in the United States.
OBJECTIVE: The purpose of this review paper is to analyze smoking cost studies and to provide estimates that represent the economic costs of smoking from different perspectives of society, and as a whole.
METHODS: Current Contents (1996–), Health Star (1970–), and Medline (1966–) databases were searched through the use of pertinent subject headings and key words: tobacco use, smoking, cost, and economics. The internet was utilized to identify potential sources of epidemiological and cost information on smoking. Recent cost-of-illness studies using different methodologies: human capital, incidence, and prevalence were chosen for review based on their relevance.
RESULTS: Preliminary results indicate that the published cost studies available underestimate the "true" costs of smoking. The most current articles approximate annual direct medical costs to health care payers of $50 billion (1993); inflating to 1997 equals $59 billion or $1,200 per smoker. Although the latest cost studies do not attempt to estimate indirect costs, past studies have found indirect costs to be 1.5–2 times the direct costs. Therefore, using direct and indirect costs we estimate total smoking costs to be $150 billion (1993); inflating to 1997 equals $176 billion or $3,500 per smoker.
CONCLUSION: Quantifying the cost of smoking is a difficult task due to tobacco use infiltrating many aspects of life and the dependency of cost on perspective. Cost-of-illness studies provide cost estimation data which can be useful in aiding decision-makers who are allocating health care resources.     

A national surveillance system for tracking tobacco news stories

BACKGROUND: Two of the major goals of tobacco prevention and control activities are to change social norms and influence policy. The news media can play an important role for achieving both goals. METHODS: The Centers for Disease Control and Prevention's Office on Smoking and Health created a surveillance system to track tobacco stories in the news media beginning in 2004. The system was developed based on reviewing lessons from previous news media tracking efforts, including defining the purpose of the system, using a parsimonious approach to sample media outlets, and attending to data-quality issues. Tobacco news stories were systematically identified and coded from ten newspapers, four news wire services, and seven national television networks. RESULTS: Findings indicated that from January 2004 through June 2005, tobacco-related stories were in selected major newspapers virtually every day. More than 70% of all newspaper stories contained one of only three main story themes: policy or regulation (31.0%), legal issues (23.8%), or health effects or statistics (18.1%). Television news stories on tobacco were much less common, but increased substantially during the first 6 months of 2005 compared to 2004. Health effects/statistics (50.5%) were the dominant theme for television, with policy/regulation a distant second (19.5%). CONCLUSIONS: Tobacco-related media coverage can be systematically tracked and characterized. These findings may have value to public health researchers and policymakers who wish to evaluate efforts to curb tobacco-related disease.     

Paradoxical correlations of cyclin-dependent kinase inhibitors p21waf1/cip1 and p27kip1 in metastatic colorectal carcinoma.

The cyclin-dependent kinase inhibitors (CDIs) p27kip1 and p21waf1/cip1 are key cell cycle-negative regulatory enzymes. The objective of this study was to correlate expression of p27kip1 and p21waf1/cip1 with survival, chemotherapy responsiveness, and expression of the proliferation marker Ki-67 in patients with advanced colorectal cancer. Immunohistochemistry was performed with antibodies to p27kip1, p21waf1/cip1, and Ki-67 on samples from 66 patients with metastatic colorectal carcinoma. Interpretation was performed by visual inspection and automated image analysis. Patients who obtained a response to chemotherapy had greater p21waf1/cip1 tumor staining with a mean of 10.0 positive cells/high-powered field, compared with 4.5 positive cells/high-powered field for nonresponders (P = 0.03). A positive Spearman correlation was seen between Ki-67 and p27kip1 (r = 0.48; P = 0.0001), as well as between Ki-67 and p21waf1/cip1 (r = 0.48; P = 0.0001). A trend toward shorter survival was seen in patients with positive specimens (median survival of 10 months for patients with both p27kip1- and p21waf1/cip1-positive specimens, compared with 22 months for patients with neither p27kip1- nor p21waf1/cip1-positive specimens). In contrast to that previously reported in normal colonic mucosa or early-stage colorectal cancer, we observed positive correlations of Ki-67 with both p27kip1 and p21waf1/cip1, a trend toward greater CDI staining indicating worse prognosis, and greater p21waf1/cip1 staining in tumors that were chemosensitive. These findings suggest that in the metastatic setting, CDIs may show altered function, compared with their role in the normal cell cycle.     

Quantifying radiation therapy-induced brain injury with whole-brain proton MR spectroscopy: initial observations.

PURPOSE: To quantify the extent of neuronal cell loss imparted to the brain by means of radiation therapy through the decline of the amino acid derivative N-acetylaspartate (NAA) by using proton (hydrogen 1) magnetic resonance (MR) spectroscopy. MATERIALS AND METHODS: Proton MR spectroscopy in a clinical MR imager was used to ascertain the amount of whole-brain NAA before and immediately after whole-brain radiation therapy 3-4 weeks later. Eight patients (four women, four men; median age, 55 years; age range, 39-70 years) were studied. All subjects had lung cancer (non-small cell lung cancer [n = 5], small-cell lung cancer [n = 3]) and received either palliative or prophylactic whole-brain radiation therapy. Six of them also underwent a Mini-Mental Status Examination (MMSE) for correlation with the whole-brain NAA. Two-tailed Student t tests were used to evaluate the data. RESULTS: A significant (P = .042) average decline in whole-brain NAA of -0.91 mmol per person was observed in the cohort. No corresponding changes occurred in MMSE scores. There was no significant difference in whole-brain NAA decline between prophylactic and therapeutic whole-brain radiation therapy. CONCLUSION: Since whole-brain NAA loss was detected even when MMSE scores were unchanged, the former seems to be a more sensitive measure of radiation therapy injury than is the latter.     

Percutaneous removal of residual intrahepatic stones

In the Orient there is a high frequency of residual intrahepatic stones after biliary tract surgery. Percutaneous removal of residual intrahepatic stones was attempted in a group of 74 patients. Stones were exclusively intrahepatic in 57 patients, whereas 17 patients also had stones in the common bile duct. Biliary strictures were present in 60 cases (81%). A combination of techniques was used, including preshaped angulated catheters, irrigation-suction, balloon dilation of strictures, and crushing of large stones. In 36 cases all stones were removed and in 14 cases most stones were removed, for a success rate of 67.6%. Biliary stricture was the factor most often responsible for failure.     

Progesterone treatment during the early follicular phase of the menstrual cycle: effects on smoking behavior in women.

The goals of this study were (1) to examine the feasibility of administering progesterone to women during the early follicular phase when the endogenous estradiol and progesterone levels are low, and (2) to investigate the effects of oral progesterone treatment on smoking behavior in female smokers. Twelve subjects had two experimental sessions, within 3-9 days after the beginning of their menses. In each experimental session, subjects received a single 200-mg dose of progesterone or placebo, orally. Two and a half hours after the medication treatment, subjects were assessed for subjective response to two puffs of a cigarette and then started the self-administration period in which they had the option to exchange their token for two puffs of cigarette, 15 min apart. Subjects had low levels of estradiol and progesterone before the first and second sessions. Plasma progesterone levels peaked in 2 h following progesterone treatment. Progesterone treatment attenuated the craving for and subjective effects from smoking. Under progesterone treatment, there was a trend for decreased smoking behavior. These preliminary results suggest that the early follicular phase of the menstrual cycle may be a useful interval to investigate the effects of exogenous progesterone in female smokers. The effects of progesterone on nicotine dependence need to be studied further.
