RESUMEN
Maternal systemic inflammation during pregnancy may restrict embryo-fetal growth, but the extent of this effect remains poorly established in undernourished populations. In a cohort of 653 maternal-newborn dyads participating in a multi-armed, micronutrient supplementation trial in southern Nepal, we investigated associations between maternal inflammation, assessed by serum α1-acid glycoprotein and C-reactive protein, in the first and third trimesters of pregnancy, and newborn weight, length and head and chest circumferences. Median (IQR) maternal concentrations in α1-acid glycoprotein and C-reactive protein in the first and third trimesters were 0.65 (0.53-0.76) and 0.40 (0.33-0.50) g/l, and 0.56 (0.25-1.54) and 1.07 (0.43-2.32) mg/l, respectively. α1-acid glycoprotein was inversely associated with birth size: weight, length, head circumference and chest circumference were lower by 116 g (P = 2.3 × 10-6), and 0.45 (P = 3.1 × 10-5), 0.18 (P = 0.0191) and 0.48 (P = 1.7 × 10-7) cm, respectively, per 50% increase in α1-acid glycoprotein averaged across both trimesters. Adjustment for maternal age, parity, gestational age, nutritional and socio-economic status and daily micronutrient supplementation failed to alter any association. Serum C-reactive protein concentration was largely unassociated with newborn size. In rural Nepal, birth size was inversely associated with low-grade, chronic inflammation during pregnancy as indicated by serum α1-acid glycoprotein.

BACKGROUND: To reduce the negative consequences of smoking, workplaces have adopted and implemented anti-smoking initiatives. Compared to large workplaces, less research exists about these initiatives at smaller workplaces, which are more likely to hire low-wage workers with higher rates of smoking. The purpose of this study was to describe and compare the smoking policies and smoking cessation activities at small (20-99 employees) and very small (< 20 employees) workplaces. METHODS: Thirty-two key informants coming from small and very small workplaces in Iowa completed qualitative telephone interviews. Data collection occurred between October 2016 and February 2017. Participants gave descriptions of the anti-smoking initiatives at their workplace. Additional interview topics included questions on enforcement, reasons for adoption, and barriers and facilitators to adoption and implementation. The data were analyzed using counts and content and thematic analysis. RESULTS: Workplace smoking policies were nearly universal (n = 31, 97%), and most workplaces (n = 21, 66%) offered activities to help employees quit smoking. Reasons for adoption included the Iowa Smokefree Air Act, to improve employee health, and organizational benefits (e.g., reduced insurance costs). Few challenges existed to adoption and implementation. Commonly cited facilitators included the Iowa Smokefree Air Act, no issues with compliance, and support from others. Compared to small workplaces, very small workplaces offered cessation activities less often and had fewer tobacco policy restrictions. CONCLUSIONS: This study showed well-established tobacco control efforts in small workplaces, but very small workplaces lagged behind. To reduce potential health disparities in smoking, future research and intervention efforts in tobacco control should focus on very small workplaces.

Research in sociology suggests that the effects of standards are not nearly as straightforward or as homogenising as they first appear. The present study extends these insights by demonstrating how even standards designed simply to collect data can produce extensive and unanticipated effects in medical fields as their uses evolve across actors and contexts. We draw on an embedded case study exploring the multifaceted consequences of the use of a practice-driven voluntary documentation standard: the Swedish rheumatology quality registry from 1995-2014. Data collection included document analysis; 100 interviews with specialists, patients and stakeholders in the field; fieldwork; and observations of physician-patient encounters. Our findings show that the scope and influence of the registry increased over time, and that this standard and its evolution contributed to changes in rheumatologist clinical practice, research practice, and governmental practice. These findings suggest that even initially 'weak', voluntary forms of standardisation can generate far-reaching and unpredictable consequences for the performance and delivery of care as well as for the development of a medical field. Future work about how standards can contribute both to uniformity and diversity is warranted.

In light of research that shows the importance of effective sexual communication for healthier sexual relationships, less unwanted sexual activity, and less sexual violence, this article explores how both dominant and alternative sexual scripts influence sexual communication. Drawing on 51 in-depth interviews with adults in heterosexual, queer, non-monogamous, and kink sex communities about their actual communication and consent practices in sexual interactions, we asked 1) In what ways do dominant sexual scripts affect communication and consent in sexual interactions? 2) What factors encourage people to diverge from these dominant scripts? and 3) How do alternative scripts produce new forms of communication and consent? We found that traditional scripts remain common, especially among those with less sexual experience, and that adherence to these scripts is more likely to correspond to coercive or unwanted sex. Conversely, exposure to alternative sexual scripts via sexual experience, education, or communities often encourages sexual agency and communication. We conclude by discussing the implications of these insights about communicative consent negotiations for sexual violence prevention.

BACKGROUND: There is currently a lack of understanding regarding the link between ABO blood types with outcomes of traumatically injured patients. The purpose of this study was to determine the association of ABO blood types with outcomes in traumatically injured patients separated by injury type. METHODS: This retrospective study evaluated trauma patients at an urban, Level 1 trauma center from January 1, 2017, through December 31, 2017. Patients were excluded if they were pregnant or <16 years old. Recorded outcomes included: ABO blood group, mortality, Injury Severity Score (ISS), race, injury type, mechanism of injury, and complications. Data analysis was performed using descriptive statistics including Chi-squared, Kruskal-Wallis, and F-test calculations. RESULTS: A total of 3779 patients were included in this study. No significant differences were present in mean age or ISS between blood types. In patients with penetrating injuries, blood type O was associated with a significant increase in mortality (P = 0.017), red blood cell transfusion (P = 0.027), and massive transfusion protocol (MTP) (P = 0.026) compared to non-O blood types. In patients with blunt injuries, blood type AB was associated with a significant increase in mortality rate compared to non-AB blood types (P = 0.03). CONCLUSION: ABO blood type is connected with an underlying process which affects trauma outcomes, including mortality. Blood type O is associated with increased blood transfusion, MTP, and mortality during the initial hospitalization following a traumatic penetrating injury, while blood type AB is associated with increased mortality during the initial hospitalization following a blunt traumatic injury.
RESUMEN
BACKGROUND: Smaller workplaces frequently employ low-wage earners, who have higher smoking rates. Organizational culture and workplace health climate are two characteristics that could influence employee smoking. The purpose of this study was to examine the associations between organizational culture, workplace health climate, and smoking among employees at small (20-99 employees) and very small (<20 employees) workplaces. We proposed the following hypotheses: a stronger clan culture will be associated with a better workplace health climate (HP1); a better workplace health climate will be associated with lower odds of current smoking (HP2); and there will be an association between workplace health climate and smoking intensity (HP3) and between workplace health climate and quit intention (HP4). METHODS: Executives and employees completed separate online questionnaires. Data collection occurred between June and October 2017. We used regression and Fisher's exact tests to answer study hypotheses. RESULTS: Workplaces with stronger clan cultures had a better workplace health climate (b = 0.27, P < .05), providing support for HP1. A better workplace health climate was associated with lower odds of being a current smoker (odds ratio [OR] = 0.08; 95% confidence interval [CI]: 0.01, 0.53), providing support for HP2. No significant relationship existed between workplace health climate and smoking intensity (P = .50) or between workplace health climate and intention to quit smoking (P = .32); therefore, HP3 and HP4 were not supported. CONCLUSION: Certain culture types may inform an organization's health climate. Despite a lower likelihood of current smoking in workplaces with better health climates, a better health climate may not be sufficient to produce changes in smoking behavior and intentions.
RESUMEN
BACKGROUND: Implementation science experts define champions as "supporting, marketing, and driving through an implementation, overcoming indifference or resistance that the intervention may provoke in an organization." Many hospitals use designated clinical champions-often called "hand hygiene (HH) champions"-typically to improve hand hygiene compliance. We conducted an ethnographic examination of how infection control teams in the Veterans Health Administration (VHA) use the term "HH champion" and how they define the role. METHODS: An ethnographic study was conducted with infection control teams and frontline staff directly involved with hand hygiene across 10 geographically dispersed VHA facilities in the USA. Individual and group semi-structured interviews were conducted with hospital epidemiologists, infection preventionists, multi-drug-resistant organism (MDRO) program coordinators, and quality improvement specialists and frontline staff from June 2014 to September 2017. The team coded the transcripts using thematic content analysis content based on a codebook composed of inductive and deductive themes. RESULTS: A total of 173 healthcare workers participated in interviews from the 10 VHA facilities. All hand hygiene programs at each facility used the term HH champion to define a core element of their hand hygiene programs. While most described the role of HH champions as providing peer-to-peer coaching, delivering formal and informal education, and promoting hand hygiene, a majority also included hand hygiene surveillance. This conflation of implementation strategies led to contradictory responsibilities for HH champions. Participants described additional barriers to the role of HH champions, including competing priorities, staffing hierarchies, and turnover in the role. CONCLUSIONS: Healthcare systems should consider narrowly defining the role of the HH champion as a dedicated individual whose mission is to overcome resistance and improve hand hygiene compliance-and differentiate it from the role of a "compliance auditor." Returning to the traditional application of the implementation strategy may lead to overall improvements in hand hygiene and reduction of the transmission of healthcare-acquired infections.

Phase II of the Protein Structure Initiative, funded by the NIH NIGMS (National Institute of General Medical Sciences), is a 5-year effort to determine thousands of protein structures. The New York SGX Research Center for Structural Genomics (NYSGXRC) is one of the four large-scale production centers tasked with determining 100-200 structures annually. Almost all protein production is carried out using the high throughput structural biology platform at SGX Pharmaceuticals (SGX), which supplies 120 or more ultrapure proteins per month for NYSGXRC crystallization and structure determination activities. Protocols for PCR, cloning, expression/solubility testing, fermentation, purification, and crystallization are described. General protocols and detailed experimental results for each target are updated weekly at the public PepcDB website (pepcdb.pdb.org/), and all NYSGXRC clones should be available in 2008 through the PlasmID resource operated by the Harvard Institute of Proteomics.

Importance: Audit and feedback based on direct observation is a common strategy to improve hand hygiene compliance, but the optimal design and delivery of this intervention are poorly defined. Objective: To describe barriers encountered by audit-and-feedback programs for hand hygiene across acute care hospitals within the Veterans Health Administration. Design, Setting, and Participants: A qualitative study was conducted at a geographically diverse convenience sample of 10 acute care hospitals within the Veterans Health Administration. Participants included 108 infection prevention team personnel and frontline staff. All data were collected between June 30, 2014, and March 18, 2015. Data were analyzed between September 6, 2017, and January 5, 2018. Main Outcomes and Measures: Barriers to audit and feedback for hand hygiene compliance were evaluated. Semistructured interviews of key personnel were performed through site visits at 6 locations and telephone interviews with 4 sites. Focus groups were conducted with frontline staff. Interviews and focus groups were audio recorded and transcribed. All transcripts were analyzed using thematic content analysis. Results: Overall, 108 individuals participated in the study. Semistructured interviews were conducted with 38 individuals, who were predominantly infection prevention team members. Focus group interviews were conducted with 70 frontline hospital staff members. Surveillance activities at all 10 sites made use of a variety of staff members with the intention of covertly collecting direct observations on hand hygiene compliance. Monitoring programs were challenging to maintain because of constraints on time and personnel. Both auditors and frontline staff expressed skepticism about the accuracy of compliance data based on direct observations. Auditors expressed concern about the Hawthorne effect, while frontline staff were worried that their compliance was not visible to auditors. In most hospitals, approaches to monitoring hand hygiene compliance produced friction between frontline staff and infection prevention teams. The feedback process for audit results did not consistently reach frontline staff and, in many hospitals, did not seem to facilitate improvement efforts. Conclusions and Relevance: Auditing hand hygiene compliance with direct observation was problematic across these acute care hospitals. Auditing was perceived to collect inaccurate data and created tension with frontline staff, and the feedback process did not appear to encourage positive change. Strategies are needed to collect more reliable hand hygiene data and facilitate multidisciplinary collaboration toward improved compliance.

INTRODUCTION: Many workplaces have adopted anti-smoking initiatives to reduce smoking behavior, but small workplaces are less likely to adopt these initiatives. One factor that could influence adoption is organizational culture, defined as the values and assumptions shared by members of an organization. The aim of this study was to examine the types of organizational culture associated with smoking policy strength and adoption of smoking cessation activities at small (20-99 employees) and very small (<20 employees) workplaces. Two study hypotheses were made: An increase in clan culture (characterized by participation in decision-making and human resources development) will be associated with an increase in smoking policy strength (H1) and higher odds of having cessation activities in the workplace (H2). METHODS: Between June and October 2017, executives and employees coming from small and very small workplaces participated in separate surveys. Executives answered questions about their workplace's anti-smoking initiatives, while employees completed a 12-item questionnaire about organizational culture. We aggregated employee data to perform linear and logistic regression at the organizational level. RESULTS: Organizational culture was not significantly associated with smoking policy strength, therefore H1 was not supported. Counter to H2, an increase in clan culture was associated with lower odds of offering smoking cessation activities (OR=0.06; 95% CI: 0.01-0.58). CONCLUSIONS: We did not find support for the hypothesized relationships. External factors and additional cultural characteristics may explain study findings. Continued research on culture and ways to improve tobacco control within smaller workplaces is needed.
