Content of First Prenatal Visits.

Objective The purpose of this study was to examine the content of the first prenatal visit within an academic medical center clinic and to compare the topics discussed to 2014 American College of Obstetrics and Gynecologists guidelines for the initial prenatal visit. Methods Clinical interactions were audio recorded and transcribed (n = 30). A content analysis was used to identify topics discussed during the initial prenatal visit. Topics discussed were then compared to the 2014 ACOG guidelines for adherence. Coded data was queried though the qualitative software and reviewed for accuracy and content. Results First prenatal visits included a physician, nurse practitioner, nurse midwife, medical assistant, medical students, or a combination of these providers. In general, topics that were covered in most visits and closely adhered to ACOG guidelines included vitamin supplementation, laboratory testing, flu vaccinations, and cervical cancer screening. Topics discussed less often included many components of the physical examination, education about pregnancy, and screening for an identification of psychosocial risk. Least number of topics covered included prenatal screening. Conclusions for Practice While the ACOG guidelines may include many components that are traditional in addition to those based on evidence, the guidelines were not closely followed in this study. Identifying new ways to disseminate information during the time constrained initial prenatal visit are needed to ensure improved patient outcomes.

A multi-organ, lung-derived inflammatory response following in vitro airway exposure to cigarette smoke and next-generation nicotine delivery products.

Despite increasing use of in vitro models that closely resemble in vivo human biology, their application in understanding downstream effects of airway toxicity, such as inflammation, are at an early stage. In this study, we used various assays to examine the inflammatory response induced in MucilAir™ tissues and A549 cells exposed to three products known to induce toxicity. Reduced barrier integrity was observed in tissues following exposure to each product, with reduced viability and increased cytotoxicity also shown. Similar changes in viability were also observed in A549 cells. Furthermore, whole cigarette smoke (CS) induced downstream phenotypic THP-1 changes and endothelial cell adhesion, an early marker of atherosclerosis. In contrast, exposure to next-generation delivery product (NGP) aerosol did not induce this response. Cytokine, histological and RNA analysis highlighted increased biomarkers linked to inflammatory pathways and immune cell differentiation following exposure to whole cigarette smoke, including GM-CSF, IL-1ß, cleaved caspase-3 and cytochrome P450 enzymes. As a result of similar observations in human airway inflammation, we propose that our exposure platform could act as a representative model for studying such events in vitro. Furthermore, this model could be used to test the inflammatory or anti-inflammatory impact posed by inhaled compounds delivered to the lung.

Social touch during development: Long-term effects on brain and behavior.

In this paper, our goal is to explore what is known about the role of social touch during development. We first address the neural substrates of social touch and the role of tactile experience in neural development. We discuss natural variation in early exposure to social touch, followed by a discussion on experimental manipulations of social touch during development and "natural experiments", such as early institutionalization. We then consider the role of other developmental and experiential variables that predict social touch in adults. Throughout, we propose and consider new theoretical models of the role of social touch during development on later behavior and neurobiology.

Effect of electromagnetic field exposure on chemically induced differentiation of friend erythroleukemia cells.

Whether exposure of humans to extremely low frequency electromagnetic fields (ELF-EMF) can cause cancer is controversial and therefore needs further research. We used a Friend erythroleukemia cell line that can be chemically induced to differentiate to determine whether ELF-EMF could alter proliferation and differentiation in these cells in a manner similar to that of a chemical tumor promoter. Exposure of this cell line to 60 Hz ELF-EMF resulted in a dose dependent inhibition of differentiation, with maximal inhibition peaking at 40% and 40 mG (4 microT). ELF-EMF at 10 mG (1.0 microT) and 25 mG (2.5 microT) inhibited differentiation at 0 and 20%, respectively. ELF-EMF at 1.0 (100) and 10.0 G (1,000 microT) stimulated cell proliferation 50% above the sham-treated cells. The activity of telomerase, a marker of undifferentiated cells, decreased 100[times] when the cells were induced to differentiate under sham conditions, but when the cells were exposed to 0.5 G (50 microT) there was only a 10[times] decrease. In summary, ELF-EMF can partially block the differentiation of Friend erythroleukemia cells, and this results in a larger population of cells remaining in the undifferentiated, proliferative state, which is similar to the published results of Friend erythroleukemia cells treated with chemical-tumor promoters.

The importance of interpersonal communication in poison centers.

BACKGROUND: Poison control center (PCC) personnel face many challenges in communicating with callers and with each other. The purpose of this study was to identify interpersonal communication issues that affect the work environment within PCCs. METHODS: As part of a larger questionnaire study distributed electronically to members of the American Association of Poison Control Centers (AAPCC) to assess communication training needs for PCCs, three questions were included to assess interpersonal communication within the work environment: (1) How important is interpersonal communication within your center to a positive work environment? (not at all to extremely important, 1-7); (2) How disruptive is interpersonal communication to your work? (not at all to extremely disruptive, 1-7); and (3) What communication issues do you find most disruptive to your work? (free-text response). Descriptive and qualitative content analyses were used to identify themes in responses. RESULTS: A total of 537 responses were received from SPIs, directors, medical directors, and other PCC staff. Interpersonal communication within the PCC was rated as extremely important to a positive work environment (median = 7 and IQR = 6-7; 62.3% rated as extremely important). Interpersonal communication was rated as less than moderately disruptive on average (median = 3 and IQR = 2-4). Free-text responses were received from 335 (62%) respondents. Free-text comments were broadly categorized as relating to PCC personnel and work environment and issues related to PCC callers. Categories that emerged from the PCC personnel and work environment category included the following: poor interpersonal communication (n = 104; 31%); background noise (n = 96; 29%); poor work procedures (n = 51; 15%); and poor management communication (n = 38; 11%). CONCLUSION: Interpersonal communication within PCCs was considered to be important for a positive work environment. Although not found to be strongly disruptive by most respondents, several specific interpersonal communication issues were identified by PCC personnel as disruptive to their work.

Factors affecting nasogastric tube insertion.

This study examines the effects of a patient's level of consciousness and the degree of nasogastric (NG) tube flexibility on the ease of NG tube insertion in patients who already have an endotracheal tube in place. The sample consisted of 121 patients who were admitted to the respiratory ICU of a large teaching hospital, where they underwent endotracheal intubation and subsequent placement of an NG tube. The number of attempts required for successful placement of each tube was recorded over a 4-month period and the data analyzed using a 2 X 3 factorial design. The 2 independent variables were degree of NG tube flexibility (flexible or rigid) and degree of patient consciousness (conscious, obtunded, or unconscious). The dependent variable was the number of attempted insertions per patient. The degree of NG tube flexibility significantly affected the ease with which the NG tube was inserted; the rigid tube required fewer insertion attempts than the flexible tube. The differences among levels of patient consciousness were not statistically significant, but there was a relatively strong, statistically significant interaction between the degree of tube flexibility and level of patient consciousness.

Feasibility and acceptability of a specialist clinical service for HIV-infected mineworkers in South Africa.

Occupational settings offer an ideal opportunity to provide preventive health services for HIV-infected workers. A specialized clinic was established in a mining hospital in the Free State, South Africa, with the primary aim of delivering preventive therapy such as isoniazid to those at high risk of tuberculosis (individuals with HIV infection or silicosis), and cotrimoxazole to those at highest risk for opportunistic infections. The clinic design has taken regard of the importance of minimizing stigma, protecting confidentiality, monitoring potential side effects, supporting adherence and identification of prophylaxis failure. The clinic opened in April 1999 and, by August 2001, 1773 patients had attended at least once; 1762 are HIV-infected and 11 have silicosis. Of those with HIV infection, most were asymptomatic at their first visit. The clinic has achieved high acceptability: 99% of persons who were actively recruited to the service agreed to attend. The number still attending after a median of 13 months from recruitment was 1,270 (72%) and only 48 (2.7%) have declined continued attendance. Most losses were due to termination of employment unrelated to a medical condition. The clinic has already been successfully replicated in two other regions of the mining health service in South Africa and provides a model for workplace HIV clinical services that could be used for implementation of further interventions such as antiretroviral therapy.
