Microbial Monitoring

The need for monitoring both areas for alteration in microbial flora, which may result in invasion or adverse effect on internal organs of the host, has been an accepted scientific fact of modern medicine for years. Questions remain, however, on how much monitoring needs to be done. What areas of the patients and the environment should be tested, and what are the practical uses of the results of such monitoring? Before attempting to answer these questions, let me give you an overview of how microbial monitoring has been used at the Medical College of Virginia hospitals and other institutions to identify and solve problems related to nosocomial and opportunistic infection

The Documentation of Communicable Diseases in Peruvian Mummies

Communicable disease in Egyptian mummies was documented by Ruffer and Ferguson when early in this century they reported a case of smallpox. A case of schistosomiasis was also reported by Ruffer. Various intestinal parasites have been reported from mummies, and suggestive evidence has been presented for poliomyelitis and tuberculosis. Much of this work was done at a time when good laboratory techniques were not available

A Review of Some Aspects of L-Forms and Gonococci

Systemic manifestations of gonococcal disease, such as arthritis, are often sterile on the usual culture methods used to grow gonococci. Allergic mechanisms have been invoked to explain this but with little evidence to support the concept. With the report by Holmes et al., that L-forms of gonococci were isolated from joint fluid of a patient with gonococcal arthritis, we decided to investigate the possible role of L-forms in gonococcal disease

Vaginal Flora in Postmenopausal Women: The Effect of Estrogen Replacement

Objective:To determine the effect of estrogen replacement therapy (ERT) on the vaginal flora of postmenopausal women

Comparison of Culture and Rapid Enzyme Immunoassay for the Detection of Group B Streptococcus in High-Risk Pregnancies

Objective: The purpose of this study was to evaluate the Equate Strep B® test for clinical use in patients at high risk for complications from group B streptococcus (GBS) disease. Methods: Vaginoperineal swabs were obtained from patients with preterm premature rupture of the membranes and/or preterm labor and semiquantitative GBS cultures and Equate® assay were performed. Results: From May 14, 1990, to April 30, 1992, 650 patients were enrolled; 626 had both culture and Equate® results available, of whom 24% were colonized with GBS. The sensitivity, specificity, positive predictive value, and negative predictive value of the rapid assay were 28%, 84%, 35%, and 79%, respectively. Although the prevalence of GBS was higher in patients with ruptured membranes compared with those with intact membranes, rupture of membranes did not affect test sensitivity or specificity. Conclusions: We conclude that the Equate® rapid assay is not a sensitive method of GBS detection in high-risk patients

Developing physical activity interventions for adults with spinal cord injury. Part 2: Motivational counseling and peer-mediated interventions for people intending to be active

Objective: The majority of people with spinal cord injury (SCI) do not engage in sufficient leisure-time physical activity (LTPA) to attain fitness benefits; however, many have good intentions to be active. This paper describes two pilot interventions targeting people with SCI who are insufficiently active but intend to be active (i.e., intenders ). Method: Study 1 examined the effects of a single, telephone-based counseling session on self-regulatory efficacy, intentions, and action plans for LTPA among seven men and women with paraplegia or tetraplegia. Study 2 examined the effects of a home-based strengthtraining session, delivered by a peer and a fitness trainer, on strength-training task self-efficacy, intentions, action plans, and behavior. Participants were 11 men and women with paraplegia. Results: The counseling session (Study 1) yielded medium- to large-sized increases in participants\u27 confidence to set LTPA goals and intentions to be active. The home visit (Study 2) produced medium- to large-sized increases in task self-efficacy, barrier self-efficacy, intentions, action planning, and strength-training behavior from baseline to 4 weeks after the visit. Conclusions/Implications: Study 1 findings provide preliminary evidence that a single counseling session can impact key determinants of LTPA among intenders with SCI. Study 2 findings demonstrate the potential utility of a peer-mediated, home-based strength training session for positively influencing social cognitions and strength-training behavior. Together, these studies provide evidence and resources for intervention strategies to promote LTPA. among intenders with SCI, a population for whom LTPA interventions and resources are scarcely available. © 2013 American Psychological Association

Neighbourhood, Route and Workplace-Related Environmental Characteristics Predict Adults' Mode of Travel to Work

Commuting provides opportunities for regular physical activity which can reduce the risk of chronic disease. Commuters' mode of travel may be shaped by their environment, but understanding of which specific environmental characteristics are most important and might form targets for intervention is limited. This study investigated associations between mode choice and a range of objectively assessed environmental characteristics.Participants in the Commuting and Health in Cambridge study reported where they lived and worked, their usual mode of travel to work and a variety of socio-demographic characteristics. Using geographic information system (GIS) software, 30 exposure variables were produced capturing characteristics of areas around participants' homes and workplaces and their shortest modelled routes to work. Associations between usual mode of travel to work and personal and environmental characteristics were investigated using multinomial logistic regression.Of the 1124 respondents, 50% reported cycling or walking as their usual mode of travel to work. In adjusted analyses, home-work distance was strongly associated with mode choice, particularly for walking. Lower odds of walking or cycling rather than driving were associated with a less frequent bus service (highest versus lowest tertile: walking OR 0.61 [95% CI 0.20–1.85]; cycling OR 0.43 [95% CI 0.23–0.83]), low street connectivity (OR 0.22, [0.07–0.67]; OR 0.48 [0.26–0.90]) and free car parking at work (OR 0.24 [0.10–0.59]; OR 0.55 [0.32–0.95]). Participants were less likely to cycle if they had access to fewer destinations (leisure facilities, shops and schools) close to work (OR 0.36 [0.21–0.62]) and a railway station further from home (OR 0.53 [0.30–0.93]). Covariates strongly predicted travel mode (pseudo r-squared 0.74).Potentially modifiable environmental characteristics, including workplace car parking, street connectivity and access to public transport, are associated with travel mode choice, and could be addressed as part of transport policy and infrastructural interventions to promote active commuting
