Do acetyl salicylic acid and terbutaline in combination increase the probability of a clinical pregnancy in patients undergoing IVF/ICSI?

The present study investigated if acetyl salicylic acid (ASA) and terbutaline in combination increased the clinical pregnancy rate in patients undergoing in vitro fertilisation (IVF)/intra-cytoplasmic sperm injection (ICSI). A randomised controlled trial was designed, in which 167 patients were randomised to taking ASA for 9 weeks after embryo transfer and terbutaline around the time of embryo transfer as adjuvant medication. A total of 112 patients were randomised to no adjuvant medication. The clinical pregnancy rate per controlled ovarian hyperstimulation was 30.5% in the intervention group and 42.0% in the control group. This difference was not statistically significant, and we conclude that ASA and terbutaline in combination do not increase the clinical pregnancy rate after IVF/ICSI treatment.

Who's Not Protected in the Herd? Factors Associated with Vaccine-Type HPV in Unvaccinated Women.

STUDY OBJECTIVE: Evidence suggests that vaccine-type human papillomavirus (HPV) prevalence may decrease in unvaccinated women after HPV vaccine introduction, indicating herd protection. The aim of this study was to determine factors associated with vaccine-type HPV (i.e. absence of herd protection) after vaccine introduction. DESIGN: We conducted three cross-sectional studies from 2006-2014 (n = 1180): wave 1 (2006-2007), wave 2 (2009-2010), and wave 3 (2013-2014). SETTING: Participants were recruited from a hospital-based teen health center and a community health department. PARTICIPANTS: We recruited 13-26 year-old young women; those included in this analysis had not received an HPV vaccine. INTERVENTIONS AND MAIN OUTCOME MEASURES: The outcome measure was infection with at least one vaccine-type HPV (HPV6, 11, 16, 18). RESULTS: Multivariable logistic regression demonstrated that in wave 1 (before vaccine introduction), history of anal intercourse (OR = 1.8, 95% CI = 1.1-3.0), age 18-21 vs 13-17 years (OR = 2.1, CI = 1.2-3.6), and Black/multiracial vs White race (OR = 1.8, CI = 1.1-3.0) were associated with vaccine-type HPV in unvaccinated women. In wave 2, no variables were associated with HPV. In wave 3, sexually transmitted infection history (OR = 3.6, CI = 1.3-9.7) was associated with HPV. CONCLUSION: We did not identify a consistent set of modifiable risk factors associated with vaccine-type HPV after vaccine introduction across the three study waves, underscoring the urgency of vaccination for primary HPV prevention and the limitations of relying on herd protection.

Incidental Coronary Artery Calcification Seen on Low-Dose Computed Tomography Is a Risk Factor for Obstructive Coronary Artery Disease in Patients Undergoing Liver Transplant.

Incidental arterial calcification (Ca) on low-dose computed tomography (CT) prior to liver transplant (LT) may help identify those at risk for obstructive coronary artery disease (CAD). A single-center retrospective study of 358 consecutive patients who had undergone LT was performed. Of the 296 patients who met inclusion criteria, 193 patients (65.2%) had CT Ca. Aortic Ca was seen in 116 (39.2%), coronary Ca in 141 (47.6%), and peripheral Ca in 8 patients (2.7%). Patients with coronary Ca were assigned ordinal coronary artery Ca scores and classified as mild, moderate, and severe. All-cause mortality was higher in patients with Ca in any location (14.5% vs 6.8%, P = .05). Of the patients who underwent coronary angiography, those with obstructive CAD were more likely to have aortic and coronary Ca than patients with nonobstructive or no CAD (85.7% vs 50.0%, P = .02 and 92.9% vs 37.9%, P = < .001, respectively). Severe coronary artery Ca scores were more frequent in patients with obstructive CAD (35.7% vs 0%, P < .001). Any severity coronary Ca had an odds ratio of 11.57 (95% CI, 1.61-244.92; P = .04) for obstructive CAD. In conclusion, incidental coronary Ca seen on low-dose CT is a risk factor for obstructive CAD in patients undergoing LT.

Modulation of insulin receptor, insulin receptor substrate-1, and phosphatidylinositol 3-kinase in liver and muscle of dexamethasone-treated rats.

Insulin rapidly stimulates tyrosine kinase activity of its receptor resulting in phosphorylation of its cytosolic substrate, insulin receptor substrate-1 (IRS-1), which in turn associates with phosphatidylinositol 3-kinase (PI 3-kinase), thus activating the enzyme. Glucocorticoid treatment is known to produce insulin resistance, but the exact molecular mechanism is unknown. In the present study we have examined the levels and phosphorylation state of the insulin receptor and IRS-1, as well as the association/activation between IRS-1 and PI 3-kinase in the liver and muscle of rats treated with dexamethasone. After dexamethasone treatment (1 mg/kg per d for 5 d), there was no change in insulin receptor concentration in liver of rats as determined by immunoblotting with antibody to the COOH-terminus of the receptor. However, insulin stimulation of receptor autophosphorylation determined by immunoblotting with antiphosphotyrosine antibody was reduced by 46.7 +/- 9.1%. IRS-1 and PI 3-kinase protein levels increased in liver of dexamethasone-treated animals by 73 and 25%, respectively (P < 0.05). By contrast, IRS-1 phosphorylation was decreased by 31.3 +/- 10.9% (P < 0.05), and insulin stimulated PI 3-kinase activity in anti-IRS-1 immunoprecipitates was decreased by 79.5 +/- 11.2% (P < 0.02). In muscle, the changes were less dramatic, and often in opposite direction of those observed in liver. Thus, there was no significant change in insulin receptor level or phosphorylation after dexamethasone treatment. IRS-1 and PI 3-kinase levels were decreased to 38.6 and 65.6%, respectively (P < 0.01 and P < 0.05). IRS-1 phosphorylation showed no significant change in muscle, but insulin-stimulated IRS-1 associated PI 3-kinase was decreased by 41%. Thus, dexamethasone has differential effects on the proteins involved in the early steps in insulin action in liver and muscle. In both tissues, dexamethasone treatment results in a reduction in insulin-stimulated IRS-1-associated P I3-kinase, which may play a role in the pathogenesis of insulin resistance at the cellular level in these animals.

A comparison of sirolimus vs. calcineurin inhibitor-based immunosuppressive therapies in liver transplantation.

BACKGROUND: Sirolimus is a potent immunosuppressive agent whose role in liver transplantation has not been well-described. AIM: To evaluate the efficacy and side-effects of sirolimus-based immunosuppression in liver transplant patients. METHODS: Retrospective analysis of 185 patients who underwent orthotopic liver transplantation. Patients were divided into three groups: group SA, sirolimus alone (n = 28); group SC, sirolimus with calcineurin inhibitors (n =56) and group CNI, calcineurin inhibitors without sirolimus (n = 101). RESULTS: One-year patient and graft survival rates were 86.5% and 82.1% in group SA, 94.6% and 92.9% in group SC, and 83.2% and 75.2% in group CNI (P = N.S.). The rates of acute cellular rejection at 12 months were comparable among the three groups. At the time of transplantation, serum creatinine levels were significantly higher in group SA, but mean creatinine among the three groups at 1 month was similar. More patients in group SA required dialysis before orthotopic liver transplantation (group SA, 25%; group SC, 9%; group CNI, 5%; P = 0.008), but at 1 year, post-orthotopic liver transplantation dialysis rates were similar. CONCLUSIONS: Sirolimus given alone or in conjunction with calcineurin inhibitors appears to be an effective primary immunosuppressant regimen for orthotopic liver transplantation patients. Further studies to evaluate the efficacy and side-effect profile of sirolimus in liver transplant patients are warranted.

Attitudes about human papillomavirus vaccine among family physicians.

STUDY OBJECTIVE: Human papillomavirus (HPV) vaccines will soon be available for clinical use, and the effectiveness of vaccine delivery programs will depend largely upon whether providers recommend the vaccine. The objectives of this study were to examine family physicians' attitudes about HPV immunization and to identify predictors of intention to recommend immunization. DESIGN: Cross-sectional survey instrument assessing provider and practice characteristics, knowledge about HPV, attitudes about HPV vaccination, and intention to administer two hypothetical HPV vaccines. PARTICIPANTS: Surveys were mailed to a national random sample of 1,000 American Academy of Family Physicians (AAFP) members. MAIN OUTCOME MEASURE: Intention to administer two hypothetical HPV vaccines (a cervical cancer/genital wart vaccine and a cervical cancer vaccine) to boys and girls of different ages. RESULTS: One hundred fifty-five surveys (15.5%) were returned and 145 were used in the final sample. Participants reported higher intention to recommend both hypothetical HPV vaccines to girls vs. boys (P < 0.0001) and to older vs. younger adolescents (P < 0.0001). They were more likely to recommend a cervical cancer/genital wart vaccine than a cervical cancer vaccine to boys and girls (P < 0.001). Variables independently associated with intention (P < 0.05) included: female gender of provider, knowledge about HPV, belief that organizations such as the AAFP would endorse vaccination, and fewer perceived barriers to vaccination. CONCLUSIONS: Female gender, knowledge about HPV, and attitudes about vaccination were independently associated with family physicians' intention to recommend HPV vaccines. Vaccination initiatives directed toward family physicians should focus on modifiable predictors of intention to vaccinate, such as HPV knowledge and attitudes about vaccination.

Beliefs about Papanicolaou smears and compliance with Papanicolaou smear follow-up in adolescents.

OBJECTIVE: To explore qualitatively adolescent girls' understanding of Papanicolaou smears and barriers to compliance with Papanicolaou smear follow-up appointments. DESIGN: Qualitative analysis, using 3 focus groups and 15 in-depth, semistructured individual interviews. SETTING: Adolescent Clinic and Young Parents' Program at Children's Hospital, Boston, Mass. MAIN OUTCOME MEASURES: Beliefs and attitudes about Papanicolaou smears and barriers to compliance with Papanicolaou smear follow-up. RESULTS: The mean (+/- SD) age of the 15 interview participants was 18.7 (+/- 1.9) years. Knowledge about Papanicolaou smears and pelvic examinations was poor. Most participants believed that their peers receive Papanicolaou smear screening and perceived teenagers to be susceptible to cervical cancer. Perceived benefits to getting Papanicolaou smears were prevention and early detection or diagnosis, and reported barriers included pain or discomfort, embarrassment, fear of finding a problem, fear of the unknown, denial, poor communication or rapport with the provider, not wanting to look for trouble, lack of knowledge, and peers' advice. Participant-generated strategies for how providers could overcome barriers to Papanicolaou smear screening included education and the development of trusting, consistent relationships with providers. Participant-generated strategies for how providers could enhance appointment-keeping among adolescents included telephone and written reminders. CONCLUSIONS: These data support a behavioral theory-based model of adolescent compliance with Papanicolaou smear follow-up, which may help to develop strategies to enhance compliance with Papanicolaou smear follow-up appointments. These strategies include providing in-depth education about Papanicolaou smears, addressing barriers to Papanicolaou smear follow-up, focusing on appropriate provider behaviors, and instituting an appointment reminder system.

Validity of adolescent and young adult self-report of Papanicolaou smear results.

OBJECTIVE: To assess the validity of adolescent and young adult report of Papanicolaou smear results and to determine sociodemographic, cognitive, and behavioral factors associated with incorrect reporting. METHODS: We conducted a cross-sectional study of 477 female subjects aged 12 to 24 years who attended an adolescent clinic and had a previous Papanicolaou smear. Subjects completed a self-administered survey assessing self-report of Papanicolaou smear results, knowledge about Papanicolaou smears and human papillomavirus (HPV), attitudes about Papanicolaou screening and follow-up, and risk behaviors. The sensitivity, specificity, positive predictive value, and negative predictive value of self-reported results were calculated using the cytology report as the standard. Variables significantly associated with incorrect reporting were entered into logistic regression models controlling for age and race to determine independent predictors for incorrect reporting. RESULTS: Of the 477 participants, 128 (27%) had abnormal cytology reports and 66 (14%) had incorrect self-reports. Sensitivity of self-report was 0.79, specificity 0.89, positive predictive value 0.72, negative predictive value 0.92, and kappa (kappa) 0.66. The adjusted odds ratios (OR) and 95% confidence intervals (CI) of the variables comprising a logistic regression model predicting incorrect reporting were an HPV knowledge source of zero (OR 2.4, CI 1.0, 5.8), low perceived communication with the provider (OR 2.1, CI 1.1, 4.0), and no contraception at last intercourse (OR 5.5, CI 2.7, 11.0). CONCLUSION: The validity of adolescent and young adult self-reported Papanicolaou smear result is high, except among those who lack knowledge of HPV, perceive poor communication with the provider, and use contraception inconsistently.

Abdominal aortic aneurysm presenting as retroperitoneal fibrosis.

A case of abdominal aortic aneurysm which presented as retroperitoneal fibrosis followed by fatal disseminated intravascular coagulation is reported. A diagnostic aortogram should be considered in all cases of apparent idiopathic retroperitoneal fibrosis.

Practice management, health maintenance, and the use of computers in today's medical office.

It is clear that a successful medical practice needs a competent caring physician as well as office personnel who understand how to manage an office. The successful management of a practice helps achieve the goals that the physician and practice manager have established. This article has introduced ideas about how to manage and evaluate a practice. Adoption of some or all of these ideas helps provide more comprehensive and satisfying care for the physician and his or her patients.

Measurement of young women's attitudes about communication with providers regarding Papanicolaou smears.

PURPOSE: To describe the psychometric properties of a scale created to measure communication with the provider regarding Papanicolaou (Pap) smears. METHODS: A scale based on expectancy-value theory was developed and administered to 490 young women aged 12 to 24 years in an urban adolescent clinic. Psychometric properties were assessed using factor analysis to evaluate latent variables, intraclass correlation coefficient to evaluate test-retest reliability, and Cronbach coefficient alpha to evaluate internal consistency reliability. Content validity was assessed by qualitative interviews, feedback on a pilot survey, and expert review. Construct validity was evaluated by examining whether relevant health care characteristics, knowledge, and attitudes were significantly associated with perceived communication. RESULTS: Mean respondent age was 18.2 +/- 2.1 years; 50% were black and 22% Hispanic. The scale items loaded on one factor. The intraclass correlation coefficient was 0.83 and Cronbach alpha 0.95. Report of a consistent provider, report that a provider recommended a Pap smear, knowledge of Pap smears and Human Papillomavirus (HPV), intention to return for follow-up Pap smears, and positive attitudes about Pap follow-up were significantly associated with good communication. CONCLUSIONS: The scale appears to be reliable and valid as a measure of young women's communication with providers regarding Pap smears. Future research should focus on whether this newly developed scale is useful in the design and evaluation of cervical cancer prevention programs for young women.

Work-family issues and perceptions of stress among pediatric faculty and house staff.

OBJECTIVES: To examine work-family balance issues and predictors of stress related to work-family balance among pediatric house staff and faculty. METHODS: Data were obtained through an anonymous mail survey. Univariate analyses assessed associations between work-family issues (work-related factors that affect work-family balance, perceived support, work-family--related stress, and proposed solutions) and the following variables: gender, parental status, working status of spouse, and academic rank. Multiple linear regression examined independent predictors of perceived stress. RESULTS: Fifty percent of the 327 respondents cared for dependent children, and 20% expected to care for an elderly person in the next 5 years. Only 5% strongly agreed that their division or department was concerned about supporting members' work-family balance, and 4% strongly agreed that existing programs supported their needs. Eighty-three percent reported feeling stressed as a result of efforts to balance work and family. Independent predictors of stress included perceived need to choose between career and family, increasing age, dependent children, less support from colleagues and supervisors, and female gender. CONCLUSIONS: Work-family balance issues are responsible for substantial perceived stress. Academic departments should consider a commitment to supporting faculty who are struggling with these issues, including creation of work-family policies and programs, development of mentoring systems, and reexamination of existing expectations for work practices.

Microlaparoscopy with conscious sedation in adolescents with suspected pelvic inflammatory disease.

STUDY OBJECTIVE: To develop a protocol for emergency department microlaparoscopy with conscious sedation in adolescents with clinically suspected pelvic inflammatory disease (PID), and to evaluate the feasibility and tolerability of microlaparoscopy in this population. DESIGN: Prospective study involving adolescents and young adults age 13 to 24 meeting clinical criteria for uncomplicated PID. Laparoscopy subjects underwent microlaparoscopy in the Children's Hospital Emergency Department (ED) and comparison subjects were admitted for treatment of PID. Chi-square, Mann-Whitney U tests, Wilcoxon Rank Sum tests, and repeated measures of analysis of variance (MANOVA) were used for analysis. RESULTS: Twenty-four patients were enrolled: 6 laparoscopy subjects and 18 comparison subjects. Laparoscopy and comparison subjects did not differ with respect to age, mean white blood cell (WBC) count, mean temperature, or mean erythrocyte sedimentation rate. Mean surgical induction time was 13.5 minutes, operative time 19.0 minutes, and total procedure time 32.5 minutes. Mean requirement for midazolam was 2.8 mg and for fentanyl 225 microg. Pain assessment over the first 90 minutes did not differ significantly between laparoscopy and comparison subjects. Four of 6 laparoscopy subjects (67%) and 10 of 18 comparison subjects (56%) were diagnosed with PID (p = NS). CONCLUSIONS: ED microlaparoscopy appears to be feasible, safe, and well tolerated in this small sample of adolescents and young adults with suspected PID.

Incidence of sexually transmitted infections in HIV-infected and HIV-uninfected adolescents in the USA.

Little is known about the incidence of bacterial sexually transmitted infections (STIs) among HIV-infected versus HIV-uninfected adolescents. This secondary analysis of a national, multisite study included adolescents aged 12-18 years who were behaviourally HIV-infected (n = 346) or HIV-uninfected but at-risk (n = 182). Incidence rates of bacterial STIs (gonorrhoea, chlamydia [CT] and trichomonas [TV; women]) were calculated using Poisson modelling. Factors associated with incident STIs were explored using Cox proportional hazards modelling. HIV-infected versus HIV-uninfected women had higher TV incidence (1.3 versus 0.6/100 person-months; P = 0.002). HIV-uninfected versus HIV-infected women had higher CT incidence (1.6 versus 1.1/100 person-months; P = 0.04). Among women, demographic, behavioural and HIV-related factors were associated with incident STIs. Among men, there were no differences in incident STIs. In this first analysis comparing STI incidence between HIV-infected and HIV-uninfected adolescents, bacterial STI incidence among women significantly differed by HIV status, and factors associated with incident STIs varied by STI and HIV status.

Adolescents' agreement to test for HIV when different testing methods are offered.

Offering rapid HIV testing improves rates of testing in adults, but little is known about whether offering adolescents a choice of testing methods increases rates of testing. The aims of the study were to determine rates of HIV testing in adolescents when different testing methods were offered and explore factors associated with agreement to be tested for HIV. Participants (n= 200, sexually experienced 13-22 year olds) were recruited from an urban adolescent clinic, completed a 99-item theory-based survey and were offered their choice of venipuncture, rapid fingerstick or rapid oral fluid HIV testing. Approximately half (49.5%) agreed to HIV testing. Male gender, parental completion of high school, intention to test for HIV if offered by clinician and higher perceived likelihood of current HIV infection were independently associated with agreement to test. Combining new strategies, such as opt-out testing, with routine testing may be needed to improve rates of adolescent HIV testing.
