Getting to Know the Competition: A Content Analysis of Publicly and Corporate Funded Physical Activity Advertisements

The authors examine how crime and violence is reported and framed by the Los Angeles Times . Using a public health perspective, we examine whether health-oriented variables, such as causal factors and societal effects of crimes, are present in crime news stories. The classic stereotyping of crime and violence framing is strongly present in the Times . We discuss what changes would be useful to provide news consumers with a more accurate picture of crime in their community.     

A novel host-protein assay outperforms routine parameters for distinguishing between bacterial and viral lower respiratory tract infections

Bacterial and viral lower respiratory tract infections (LRTIs) are often clinically indistinguishable, leading to antibiotic overuse. We compared the diagnostic accuracy of a new assay that combines 3 host-biomarkers (TRAIL, IP-10, CRP) with parameters in routine use to distinguish bacterial from viral LRTIs. Study cohort included 184 potentially eligible pediatric and adult patients. Reference standard diagnosis was based on adjudication by an expert panel following comprehensive clinical and laboratory investigation (including respiratory PCRs). Experts were blinded to assay results and assay performers were blinded to reference standard outcomes. Evaluated cohort included 88 bacterial and 36 viral patients (23 did not fulfill inclusion criteria; 37 had indeterminate reference standard outcome). Assay distinguished bacterial from viral LRTI patients with sensitivity of 0.93 ± 0.06 and specificity of 0.91 ± 0.09, outperforming routine parameters, including WBC, CRP and chest x-ray signs. These findings support the assay's potential to help clinicians avoid missing bacterial LRTIs or overusing antibiotics.     

Does Postoperative Showering or Bathing of a Surgical Site Increase the Incidence of Infection? A Systematic Review of the Literature

Infection is one of the many postoperative complications a surgeon must attempt to control during the perioperative period. Surgeons have used a variety of modalities to prevent surgical site infection and have adhered to a variety of protocols. It has been common for foot and ankle surgeons to recommend that a patient keep the surgical incision covered and dry and to instruct the patient to avoid bathing and showering until the sutures have been removed. Surgeons have theorized that this will reduce contamination of the surgical site and help to prevent infection. We questioned the evidence basis for this practice and undertook a systematic review of electronic databases and other relevant sources regarding the incidence of infection when patients had been allowed to wet their surgical incision site by showering or bathing before suture removal. Nine studies involving 2150 patients met our inclusion criteria. No increased incidence of infection was found in the patients allowed to shower or bathe as a part of their normal daily hygiene before suture removal compared with those who were instructed to keep the site dry until suture removal.     

A Multi-Year Study of Tobacco Control in Newspaper Editorials Using Community Characteristic Data and Content Analysis Findings

We content analyzed 1,473 newspaper editorials for topic, tone, and slant, and connected the results to community characteristic data: clean indoor air ordinance status for cities, and official smoking rates for counties. The analysis occurred during a multi-year project aimed at prompting communities to adopt clean indoor air policies. The results showed that most editorials were about tobacco restrictions or ordinances, were neutral in tone, and provided factual information about tobacco control. More editorials were negatively slanted vs. positively slanted toward tobacco control. Most editorials with positive tones were published in newspapers in towns that already had clean indoor air policies. We concluded that editorials might hold increased weight in spurring change, as the percentage of smokers in a city is unrelated to the town enacting a clean indoor air ordinance.     

Elevated maternal serum-free β-human chorionic gonadotropin (β-hCG) and reduced risk of spontaneous preterm delivery*

Objective: To evaluate the relationship between first and second trimester maternal serum-free β-hCG and the risk of spontaneous preterm delivery (PTD).

Study design: This was a case-control study of women evaluated and delivered at our institution from 2011 to 2015. Spontaneous PTD was defined as delivery before 37 weeks due to spontaneous preterm labor or premature rupture of membranes. Patient with multifetal gestation and those with medically indicated term or PTD were excluded.

Results: Of 877 women meeting the inclusion criteria, 173 delivered preterm and 704 delivered at term, and 8.1% had high free β-hCG in one or both trimesters. High maternal first and/or second trimester free β-hCG (≥95th percentile) was associated with lower rates of PTD. Thirty-two women with high free β-hCG in both first and second trimesters delivered at term. Gestational age at delivery and birth weights were lower in women who did not have high free β-hCG in any trimester. Low free β-hCG (≤5th percentile) in either trimester was not associated with an increased or decreased likelihood of PTD. Logistic regression demonstrated an independent association of high free β-hCG (≥95th percentile) with a reduced likelihood of PTD. Stratified analysis revealed a stronger impact of this association in women with no prior history of PTD.

Conclusions: High free β-hCG, in the absence of risk factors for medically indicated PTD, is associated with a reduced likelihood of spontaneous PTD and may represent a marker indicating lower risk.     

Sustainable fragrance cum antimicrobial finishing on cotton: Indigenous essential oil

Fragrance finishing of textile has been enormously increased and used in domestic and industrial application. Fragrance can be synthesis chemically but available in natural and inorganic. The investigation of this research is to study the combined effect of fragrance and antimicrobial finishing on cotton fabric by lavender essential oil with the use of β-Cyclodextrin, Chitosan citrate and β-Cyclodextrin/Grafted Chitosan through pad-dry method. Fourier Transform Infrared spectroscopy (FTIR) was used to study the formation of ester bonds between β-cyclodextrin/grafted chitosan and cotton celluloses. For all the finished fabric samples fragrance release rate performance and antimicrobial properties were measure by standard test methods. The results revealed that β-CD was highly soluble in 0.6 gpl NaOH solution and 80 gpl β-CD and 6% essential lavender oil solutions were found to be a most suitable combination for fragrance and antimicrobial finishing. FTIR studies reveal about the formation of a carboxylic ester between cotton and β-Cyclodextrin/Grafted Chitosan at 1730 cm^?1 ester peak.
