Behavioral journalism newsletters to increase employee participation in a free worksite wellness center

Background. Providing an worksite fitness center for employees is an effective setting to increase an adult’s levels of physical activity, demonstrably reducing health care costs and elevating employee productivity. Increasing compliance and adherence among employees to consistently utilize an onsite facility remains a challenge.^ Purpose. To illustrate if two electronic behavioral journalism newsletters can increase employee participation in a free worksite wellness center.^ Design. A randomized control trial was implemented. ^ Setting. A large petroleum-producing corporation located in Houston, Texas Subjects.70 full or part time employees that had checked into visited the wellness center during September, October, and November 2009. ^ Intervention. Two behavioral journalism newsletters were created based on authentic community member role model interviews. Newsletters were distributed to intervention group participants via company email. Intervention and control group participant’s visits to the wellness center were monitored via a key card check in system at the facility for two weeks following the newsletter intervention.^ Analysis. Count variable statistics were used to identify rate differences between the intervention and control group wellness center visits. A binomial test for equality of proportions was used to identify differences between participants that had at least one visit to the wellness center compared with those with none.^ Results. Both intervention and control groups had a baseline of zero wellness center visits. The control group had a mean visit rate 0.441 and the intervention group had 0.857. A 0.416, almost one half more visits were found among the intervention group.^ Conclusion. This study indicates that behavioral journalism newsletters featuring a role model from within the worksite population can be a cost effective communication method to improve participation in an onsite wellness center. ^

Association of TNF-alpha genetic variants with HPV-associated oral cancer risk---a case-control study

The incidence of OSCC in younger population and in those who never smoked or drank has increased since the last decade. This increase may be attributable to increase of infection with HPV. The pro-inflammatory cytokine TNF-&agr; has the role in the pathogenesis of chronic inflammatory diseases and was found to control HPV infection in cervical cancer studies. Our study aimed to investigate the association between the four polymorphisms located in TNF-&agr; promoter region, -308(rs1800629), -857(rs1799724), -863(rs1800630) and -1031(rs1799964), and the risk of HPV-related OSCC. In this hospital-based case-control study, 325 cases and 335 controls were included. We found that HPV 16 seropositivity was associated with an increased risk of oral cancer (OR = 3.1, 95% CI, 2.1–4.6). Each of the polymorphism showed to increase the risk of HPV-related OSCC. And after combining the risk genotypes and using the low-risk group (0–1 combined risk genotypes) and HPV16 seronegativity as the reference group, only the high-risk groups (3–4 combined risk genotypes) and HPV16 seronegativity were associated with a low OR of 1.8 (95% CI, 1.1–2.8), while the low-risk and high-risk groups and HPV16 seropositivity were significantly associated with a higher OR of 2.7 (95% CI, 1.3–5.8) and 8.5 (95% CI, 3.7–19.4), respectively. In addition, the joint effects were greater among the young subjects (aged<50), males, never smokers or never drinkers, and patients with oropharyngeal cancer. Overall, the four TNF-&agr; polymorphisms, individually or collectively, would result in a significantly increased risk for HPV16-associated oral cancer in a non-Hispanic white population. More large sized studies are needed for future investigation.^

Retrospective analysis of Methicillin-Resistant Staphylococcus Aureus (MRSA) skin and Soft-Tissue Infections (SSTI) in a university hospital emergency department (ED)

Study Objective: Identify the most frequent risk factors of Community Acquired-MRSA (CA-MRSA) Skin and Soft-tissue Infections (SSTIs) using a case series of patients and characterize them by age, race/ethnicity, gender, abscess location, druguse and intravenous drug-user (IVDU), underlying medical conditions, homelessness, treatment resistance, sepsis, those whose last healthcare visit was within the last 12 months, and describe the susceptibility pattern from this central Texas population that have come into the University Medical Center Brackenridge (UMCB) Emergency Department (ED). ^ Methods: This study was a retrospective case-series medical record review involving a convenience sample of patients in 2007 from an urban public hospital's ED in Texas that had a SSTI that tested positive for MRSA. All positive MRSA cultures underwent susceptibility testing to determine antibiotic resistance. The demographic and clinical variables that were independently associated with MRSA were determined by univariate and multivariate analysis using logistic regression to calculate odds ratios (OR), 95% confidence intervals, and significance (p≤ 0.05). ^ Results: In 2007, there were 857 positive MRSA cultures. The demographics were: males 60% and females 40%, with the average age of 36.2 (std. dev. =13) the study population consisted of non-Hispanic white (42%), Hispanics (38%), and non-Hispanic black (18.8%). Possible risk factors addressed included using recreational drugs (not including IVDU) (27%) homelessness (13%), diabetes status (12.6%) or having an infectious disease, and IVDU (10%). The most frequent abscess location was the leg (26.6%), followed by the arm and torso (both 13.7%). Eighty-three percent of patients had one prominent susceptibility pattern that had a susceptibility rate for the following antibiotics: trimethoprim/sulfamethoxazole (TMP-SMX) and vancomycin had 100%, gentamicin 99%, clindamycin 96%, tetracycline 96%, and erythromycin 56%. ^ Conclusion: The ED is becoming an important area for disease transmission between the sterile hospital environment and the outside environment. As always, it is important to further research in the ED in an effort to better understand MRSA transmission and antibiotic resistance, as well as to keep surveillance for the introduction of new opportunistic pathogens into the population. ^
