A randomized controlled trial of a proactive analgesic protocol demonstrates reduced opioid use among hospitalized adults with inflammatory bowel disease.

Most hospitalized patients with inflammatory bowel disease (IBD) experience pain. Despite the known risks associated with opioids in IBD including risk for misuse, overdose, infection, readmission, and even death, opioid use is more prevalent in IBD than any other chronic gastrointestinal condition. Most hospitalized IBD patients receive opioids; however, opioids have not been shown to improve pain during hospitalization. We conducted a randomized controlled trial in hospitalized patients with IBD to evaluate the impact of a proactive opioid-sparing analgesic protocol. Wearable devices measured activity and sleep throughout their hospitalization. Chronic opioid users, post-operative, and pregnant patients were excluded. The primary endpoint was a change in pain scores from admission to discharge. Secondary endpoints included opioid use, functional activity, sleep duration and quality, and length of stay. Of 329 adults with IBD evaluated for eligibility, 33 were enrolled and randomized to the intervention or usual care. Both the intervention and control group demonstrated significant decreases in pain scores from admission to discharge (- 2.6 ± 2.6 vs. - 3.0 ± 3.2). Those randomized to the intervention tended to have lower pain scores than the control group regardless of hospital day (3.02 ± 0.90 vs. 4.29 ± 0.81, p = 0.059), used significantly fewer opioids (daily MME 11.8 ± 15.3 vs. 30.9 ± 42.2, p = 0.027), and had a significantly higher step count by Day 4 (2330 ± 1709 vs. 1050 ± 1214; p = 0.014). There were no differences in sleep duration, sleep quality, readmission, or length-of-stay between the two groups. A proactive analgesic protocol does not result in worsening pain but does significantly reduce opioid-use in hospitalized IBD patients.Clinical trial registration number: NCT03798405 (Registered 10/01/2019).

Incident Cases of Sexually Transmitted Infections among Users of Pre-Exposure Prophylaxis for HIV Prevention in Honolulu, Hawai'i.

Emtricitabine/tenofovir disoproxil fumarate [FTC-TDF] is a daily oral medication taken by HIV-negative individuals for pre-exposure prophylaxis (PrEP) to prevent human immunodeficiency virus (HIV) infection. A higher incidence of sexually transmitted infections (STIs) among PrEP users has been reported compared to STI incidence before PrEP use. Asymptomatic incident STI rates were investigated among 78 patients presenting for PrEP in Honolulu, Hawai'i, from April 2018 to May 2019. Testing for oropharyngeal gonorrhea, urethral gonorrhea and chlamydia, rectal gonorrhea and chlamydia, and syphilis was performed. Incident STI percentages were calculated at each follow-up visit. Ninety-seven percent of patients were men who have sex with men (MSM). Forty-seven percent of patients had follow-up data 6 months after initiation and 28% after 1 year. Thirty-two percent of patients self-reported an STI before initiating PrEP. More than half reported anonymous partners. There were 35 positive STI tests during the study period, and 25% of patients had one or more positive tests during this time. At initiation, 17% of patients were found to have an STI, followed by 16% at 3 months, 14% at 6 months, 8% at 9 months, and 5% at 12 months. At all visits, chlamydia was the most common STI detected; at 6 months, 18% of all rectal tests were positive for chlamydia. There were inconsistent condom use and high STI rates from screening during PrEP initiation and follow-up, offering an opportunity to identify asymptomatic STIs in this population. This study is the first report in Hawai'i of STI rates among PrEP users.

Calculating maximum morphine equivalent daily dose from prescription directions for use in the electronic health record: a case report.

To demonstrate a process of calculating the maximum potential morphine milligram equivalent daily dose (MEDD) based on the prescription Sig for use in quality improvement initiatives. To calculate an opioid prescription's maximum potential Sig-MEDD, we developed SQL code to determine a prescription's maximum units/day using discrete field data and text-parsing in the prescription instructions. We validated the derived units/day calculation using 3000 Sigs, then compared the Sig-MEDD calculation against the Epic-MEDD calculator. Of the 101 782 outpatient opioid prescriptions ordered over 1 year, 80% used discrete-field Sigs, 7% used free-text Sigs, and 3% used both types. We determined units/day and calculated a Sig-MEDD for 98.3% of all the prescriptions, 99.99% of discrete-Sig prescriptions, and 81.5% of free-text-Sig prescriptions. Analyzing opioid prescription Sigs to determine a maximum potential Sig-MEDD provides greater insight into a patient's risk for opioid exposure.

Association of markers of hemostasis with death in HIV-infected women.

: In HIV negatives, markers of hemostasis, including D-dimer, factor VIII, plasminogen activator inhibitor-1 antigen (PAI-1), and total protein S are associated with all-cause and cardiovascular disease mortality. In HIV positives, studies of D-dimer and factor VIII with death were limited to short follow-up; associations of PAI-1 and total protein S with death have not been examined. In 674 HIV-infected women from the Women's Interagency HIV Study, markers from the first visit after enrollment were exposures of interest in multivariate analyses of death (AIDS and non-AIDS) in separate models at 5 and 16 years. There were 87 AIDS and 44 non-AIDS deaths at 5 years, and 159 AIDS and 113 non-AIDS deaths at 16 years. An inverse association of total protein S quartiles with non-AIDS deaths was observed at 5 (P trend = 0.002) and 16 years (P trend = 0.02); there was no association with AIDS deaths. The third quartile of PAI-1 was associated with AIDS deaths at 5 [hazard ratio (HR) = 4.0; 95% confidence interval (CI): 1.9 to 8.4] and 16 years (HR = 3.4; 95% CI: 1.9 to 5.9); and with non-AIDS deaths at 5 years (HR = 4.8; 95% CI: 1.6 to 13.9). D-dimer and factor VIII were not associated with AIDS or non-AIDS death at 5 or 16 years. Lower total Protein S was a consistent marker of non-AIDS death. We found no association between D-dimer with AIDS or non-AIDS death, in contrast to previous studies showing increased short-term (<5 years) mortality, which may represent sex differences or population heterogeneity. Given longer survival on highly active antiretroviral therapy, further studies of these markers are needed to determine their prognostic value.

Associations of HIV infection with insulin and glucose levels in antiretroviral-naive Rwandan women: a cross-sectional analysis.

OBJECTIVES: The purpose of these analyses was to determine the associations of HIV infection and related immune dysfunction with a glucose homeostasis in the population of antiretroviral-naïve HIV-infected and uninfected Rwandan women. We hypothesise that insulin resistance and its consequences in the developing countries may be further elevated with HIV infection itself regardless of antiretroviral therapy. STUDY DESIGN: Cross-sectional analysis of a longitudinal cohort. SETTING: Community-based women's associations. PARTICIPANTS: In 2005, 710 HIV-infected (HIV positive) antiretroviral naïve and 226 HIV-uninfected (HIV negative) women were enrolled in the Rwanda Women's Interassociation Study and Assessment (RWISA). Clinical and demographic parameters, CD4 count, fasting insulin and glucose levels, anthropometric measurements and Bioelectrical Impedance Analysis (BIA) were obtained. Linear models were fit to log-transformed Homeostasis Model Assessment (HOMA) with results exponentiated back to a multiplicative effect on the original scale. PRIMARY OUTCOME MEASURES: The outcome, insulin resistance, was measured by the HOMA, calculated as fasting insulin (µU/mL)×fasting glucose (mmol/L)/22.5. RESULTS: In adjusted models, HIV-positive women were less insulin resistant than HIV-negative; an HIV-positive woman tended to have 0.728 times as much (95% CI 0.681 to 0.861) HOMA than a comparable HIV-negative woman. Among the HIV-positive women, those with CD4 <200 cells/µL tended to have 0.741 times as much HOMA (95% CI 0.601 to 0.912) as did comparable women with CD4 >350 cells/µL. The older age was independently associated with a lower HOMA insulin resistance. After adjusting for body mass index, fat and fat-free mass were not independently associated with HOMA. CONCLUSIONS: This study found that HIV infection and more advanced HIV infection (CD4 counts <200 cells/µL) were associated with greater insulin sensitivity in antiretroviral naïve African women. These findings provide baseline information for the interpretation of future studies on the effect of antiretroviral therapy on metabolic insulin sensitivity derangements in African population.

Association of hepatitis C with markers of hemostasis in HIV-infected and uninfected women in the women's interagency HIV study (WIHS).

BACKGROUND: Coinfection with HIV and hepatitis C virus (HCV) is common. HIV infection and treatment are associated with hypercoagulability; thrombosis in HCV is underinvestigated. Proposed markers of hemostasis in HIV include higher D-dimer, Factor VIII%, and plasminogen activator inhibitor-1 (PAI-1) antigen and lower total Protein S% (TPS) but have not been examined in HCV. We assessed the independent association of HCV with these 4 measures of hemostasis in a multicenter, prospective study of HIV: the Women's Interagency HIV Study. METHODS: We randomly selected 450 HCV-infected (anti-HCV+ with detectable plasma HCV RNA) and 450 HCV-uninfected (anti-HCV-) women. HCV was the main exposure of interest in regression models. RESULTS: Four hundred forty-three HCV+ and 425 HCV- women were included. HCV+ women had higher Factor VIII% (124.4% ± 3.9% vs. 101.8% ± 3.7%, P < 0.001) and lower TPS (75.7% ± 1.1% vs. 84.3% ± 1.1%, <0.001) than HCV- women, independent of HIV infection and viral load; there was little difference in PAI-1 or log10 D-dimer. After adjustment for confounders, these inferences remained. HIV infection was independently associated with higher Factor VIII% and log10 D-dimer and lower TPS. CONCLUSIONS: HCV was independently associated with higher Factor VIII% and lower TPS consistent with hypercoagulability. Higher Factor VIII% and D-dimer and lower TPS were also strongly associated with HIV infection and levels of HIV viremia, independent of HCV infection. Further investigation is needed to determine if there is increased thrombotic risk from HCV. Studies examining hemostasis markers in HIV infection must also assess the contribution of HCV infection.

Association of serum albumin with markers of nutritional status among HIV-infected and uninfected Rwandan women.

INTRODUCTION: The objectives of this study are to address if and how albumin can be used as an indication of malnutrition in HIV infected and uninfected Africans. METHODS: In 2005, 710 HIV-infected and 226 HIV-uninfected women enrolled in a cohort study. Clinical/demographic parameters, CD4 count, albumin, liver transaminases; anthropometric measurements and Bioelectrical Impedance Analysis (BIA) were performed. Malnutrition outcomes were defined as body mass index (BMI), Fat-free mass index (FFMI) and Fat mass index (FMI). Separate linear predictive models including albumin were fit to these outcomes in HIV negative and HIV positive women by CD4 strata (CD4>350,200-350 and <200 cells/µl). RESULTS: In unadjusted models for each outcome in HIV-negative and HIV positive women with CD4>350 cells/µl, serum albumin was not significantly associated with BMI, FFMI or FMI. Albumin was significantly associated with all three outcomes (p<0.05) in HIV+ women with CD4 200-350 cells/µl, and highly significant in HIV+ women with CD4<200 cells/µl (P<0.001). In multivariable linear regression, albumin remained associated with FFMI in women with CD4 count<200 cells/µl (p<0.01) but not in HIV+ women with CD4>200. DISCUSSION: While serum albumin is widely used to indicate nutritional status it did not consistently predict malnutrition outcomes in HIV- women or HIV+ women with higher CD4. This result suggests that albumin may measure end stage disease as well as malnutrition and should not be used as a proxy for nutritional status without further study of its association with validated measures.

Similar relation of age and height to lung function among Whites, African Americans, and Hispanics.

Current guidelines recommend separate spirometry reference equations for whites, African Americans, and Mexican Americans, but the justification for this recommendation is controversial. The authors examined the statistical justification for race/ethnic-specific reference equations in adults in the Third National Health and Nutrition Examination Survey (1988-1994) and the Multi-Ethnic Study of Atherosclerosis Lung Study (2000-2006). Spirometry was measured following American Thoracic Society guidelines. "Statistical justification" was defined as the presence of effect modification by race/ethnicity among never-smoking participants without respiratory disease or symptoms and was tested with interaction terms for race/ethnicity (× age and height) in regression models. There was no evidence of effect modification by race/ethnicity for forced expiratory volume in 1 second, forced vital capacity, or the forced expiratory volume in 1 second/forced vital capacity ratio among white, African-American, and Mexican-American men or women on an additive scale or a log scale. Interaction terms for race/ethnicity explained less than 1% of variability in lung function. The mean lung function for a given age, gender, and height was the same for whites and Mexican Americans but was lower for African Americans. Findings were similar in the Multi-Ethnic Study of Atherosclerosis Lung Study. The associations of age and height with lung function are similar across the 3 major US race/ethnic groups. Multiethnic rather than race/ethnic-specific spirometry reference equations are applicable for the US population.

Association of pre-treatment nutritional status with change in CD4 count after antiretroviral therapy at 6, 12, and 24 months in Rwandan women.

BACKGROUND: Body mass index (BMI) independently predicts mortality in studies of HIV infected patients initiating antiretroviral therapy (ART). We hypothesized that poorer nutritional status would be associated with smaller gains in CD4 count in Rwandan women initiating ART. METHODS AND FINDINGS: The Rwandan Women's Interassociation Study and Assessment, enrolled 710 ART-naïve HIV-positive and 226 HIV-negative women in 2005 with follow-up every 6 months. The outcome assessed in this study was change in CD4 count at 6, 12, and 24 months after ART initiation. Nutritional status measures taken prior to ART initiation were BMI; height adjusted fat free mass (FFMI); height adjusted fat mass (FMI), and sum of skinfold measurements. 475 women initiated ART. Mean (within 6 months) pre-ART CD4 count was 216 cells/µL. Prior to ART initiation, the mean (±SD) BMI was 21.6 (±3.78) kg/m(2) (18.3% malnourished with BMI<18.5); and among women for whom the following were measured, mean FFMI was 17.10 (±1.76) kg/m(2); FMI 4.7 (±3.5) kg/m(2) and sum of skinfold measurements 4.9 (±2.7) cm. FFMI was significantly associated with a smaller change in CD4 count at 6 months in univariate analysis (-6.7 cells/uL per kg/m(2), p=0.03) only. In multivariate analysis after adjustment for covariates, no nutritional variable was associated with change in CD4 count at any follow up visit. CONCLUSION: In this cohort of African women initiating ART, no measure of malnutrition prior to ART was consistently associated with change in CD4 count at 6, 12, and 24 months of follow up, suggesting that poorer pre-treatment nutritional status does not prevent an excellent response to ART.

Knowledge and attitudes of tuberculosis management in San Juan de Lurigancho district of Lima, Peru.

BACKGROUND: Expansion of the health care workforce in Peru to combat tuberculosis (TB) includes both professional health care providers (HCPs) such as doctors and nurses, and non-professional HCPs such as community health workers (CHWs). We describe the knowledge and attitudes of these HCPs, and identify modifiable barriers to appropriate anti-tuberculosis treatment. METHODOLOGY: We surveyed HCPs practicing in 30 clinical settings (hospitals, community health centers, and health posts) in the San Juan de Lurigancho district of Eastern Lima, Peru. Multiple-choice questions were used to assess knowledge of TB. A five-item Likert scale was created to assess attitudes toward the community, patients, and clinics. Linear regression was used to identify predictors of mean knowledge score, and analysis of variance was used to test differences in HCP score. RESULTS: Of the 73 HCPs surveyed, 15% were professionals (doctors or nurses). The remaining 85% were health technicians, community health workers (CHWs) or students. The mean knowledge score was 10.0 +/- 1.9 (maximum 14) with professional HCPs scoring higher than other HCPs (11.7 +/- 1.1 vs. 9.7 +/- 1.9), p < .01). Knowledge gaps included identification of patients at high risk for TB, assessment of treatment outcomes, and consequences of treatment failure. The most commonly cited modifiable barriers were structural, including laboratory facilities and staffing of TB clinics, with 52.1% and 62.5% of HCPs, respectively, citing these as problematic. CONCLUSIONS: Efforts to improve knowledge of TB HCPs in Peru should focus on the specific gaps we have identified. Further research is needed to evaluate whether these knowledge gaps correlate with TB control.

Barriers to adherence to asthma management guidelines among inner-city primary care providers.

BACKGROUND: Health care provider adherence to national asthma guidelines is critical in translating evidence-based recommendations into improved outcomes. Unfortunately, provider adherence to the National Heart, Lung, and Blood Institute (NHLBI) guidelines remains low. OBJECTIVE: To identify barriers to guideline adherence among primary care professionals providing care to inner-city, minority patients with asthma. METHODS: We surveyed 202 providers from 4 major general medicine practices in East Harlem in New York, New York. The study outcome was self-reported adherence to 5 NHLBI guideline components: inhaled corticosteroid (ICS) use, peak flow (PF) monitoring, action plan use, allergy testing, and influenza vaccination. Potential barriers included lack of agreement with guideline, lack of self-efficacy, lack of outcome expectancy, and external barriers. RESULTS: Most providers reported adhering to the NHLBI guidelines for ICS use (62%) and for influenza vaccinations (73%). Self-reported adherence was 34% for PF monitoring, 9% for asthma action plan use, and 10% for allergy testing. Multivariate analyses showed that self-efficacy was associated with increased adherence to ICS use (odds ratio [OR], 2.8; P = .03), PF monitoring (OR, 2.3; P = .05), action plan use (OR, 4.9; P = .03), and influenza vaccinations (OR, 3.5; P = .05). Conversely, greater expected patient adherence was associated with increased adherence to PF monitoring (OR, 3.3; P = .03) and influenza vaccination (OR, 3.5; P = .01). Familiarity with specific guideline components and higher level of training were also predictors of adherence. CONCLUSIONS: Lack of outcome expectancy and poor provider self-efficacy prevent providers from adhering to national asthma guidelines. Efforts to improve provider adherence should address these specific barriers.
