PreView: a Randomized Trial of a Multi-site Intervention in Diverse Primary Care to Increase Rates of Age-Appropriate Cancer Screening.

BackgroundWomen aged 50-70 should receive breast, cervical (until age 65), and colorectal cancer (CRC) screening; men aged 50-70 should receive CRC screening and should discuss prostate cancer screening (PSA). PreView, an interactive, individually tailored Video Doctor Plus Provider Alert Intervention, adresses all cancers for which average risk 50-70-year-old individuals are due for screening or screening discussion.MethodsWe conducted a randomized controlled trial in 6 clinical sites. Participants were randomized to PreView or a video about healthy lifestyle. Intervention group participants completed PreView before their appointment and their clinicians received a "Provider Alert." Primary outcomes were receipt of mammography, Pap tests (with or without HPV testing), CRC screening (FIT in last year or colonoscopy in last 10 years), and PSA screening discussion. Additional outcomes included breast, cervical, and CRC screening discussion.ResultsA total of 508 individuals participated, 257 in the control group and 251 in the intervention group. Screening rates were relatively high at baseline. Compared with baseline screening rates, there was no significant increase in mammography or Pap smear screening, and a nonsignificant increase (18% vs 12%) in CRC screening. Intervention participants reported a higher rate of PSA discussion than did control participants (58% vs 36%: P < 0.01). Similar increases were seen in discussions about mammography, cervical cancer, and CRC screening.ConclusionIn clinics with relatively high overall screening rates at baseline, PreView did not result in significant increases in breast, cervical, or CRC screening. PreView led to an increase in PSA screening discussion. Clinician-patient discussion of all cancer screenings significantly increased, suggesting that interventions like PreView may be most useful when discussion of the pros and cons of screening is recommended and/or with patients reluctant to undergo screening. Future research should investigate PreView's impact on those who are hesitant or reluctant to undergo screening.Trial registrationClinicalTrials.gov: NCT02264782

Positive Fluid Balance Is Associated with Higher Mortality and Prolonged Mechanical Ventilation in Pediatric Patients with Acute Lung Injury

Introduction. We analyzed a database of 320 pediatric patients with acute lung injury (ALI), to test the hypothesis that positive fluid balance is associated with worse clinical outcomes in children with ALI. Methods. This is a post-hoc analysis of previously collected data. Cumulative fluid balance was analyzed in ml per kilogram per day for the first 72 hours after ALI while in the PICU. The primary outcome was mortality; the secondary outcome was ventilator-free days. Results. Positive fluid balance (in increments of 10 mL/kg/24 h) was associated with a significant increase in both mortality and prolonged duration of mechanical ventilation, independent of the presence of multiple organ system failure and the extent of oxygenation defect. These relationships remained unchanged when the subgroup of patients with septic shock (n = 39) were excluded. Conclusions. Persistently positive fluid balance may be deleterious to pediatric patients with ALI. A confirmatory, prospective randomized controlled trial of fluid management in pediatric patients with ALI is warranted

comparative effectiveness of two pharmacy-based colorectal cancer screening interventions during an annual influenza vaccination campaign

J o u r n a l o f t h e A m e r i c a n P h a r m a c i s t s A s s o c i a t i o n Intervention: On five dates, eligible patients were provided education and encouraged to obtain screening from their primary care clinician. On 17 dates, a home fecal immunochemical test (FIT) for CRCS was provided. A 16-item questionnaire was administered by phone 3 to 6 months after study enrollment. Main outcome measure: Self-reported CRCS activity, comparing CRCS completion rates for participants provided with the FIT versus those provided with education and encouragement to obtain screening from patients' primary care clinician. Results: 86 participants in the FIT arm and 28 the CRCS education arm were interviewed. Interviews revealed that 19.8% of the FIT group and 50% of the CRCS education group discussed CRCS with their primary care clinician (P = 0.002). Of these participants, 59.3% in the FIT arm and 14.8% in the CRCS education arm reported completing screening (P < 0.001). Of participants in the FIT group, 52.2% completed FIT dispensed to them by the investigators. Most participants in both groups reported interest in receiving CRCS education and home CRCS tests from pharmacists in the future. Conclusion: Pharmacy patients are receptive to CRCS interventions delivered in community pharmacies. Providing FIT to eligible patients during a pharmacy-based influenza vaccination campaign increases screening rates more than CRCS education alone

Factors Influencing Physicians’ Screening Behavior for Liver Cancer Among High-risk Patients

BACKGROUND: Little is known about physicians’ screening patterns for liver cancer despite its rising incidence. OBJECTIVE: Describe physician factors associated with liver cancer screening. DESIGN: Mailed survey. PARTICIPANTS: Physicians practicing in family practice, internal medicine, gastroenterology, or nephrology in 3 northern California counties in 2004. MEASUREMENTS: Sociodemographic and practice measures, liver cancer knowledge, attitudes, and self-reported screening behaviors. RESULTS: The response rate was 61.8% (N = 459). Gastroenterologists (100%) were more likely than Internists (88.4%), family practitioners (84.2%), or nephrologists (75.0%) to screen for liver cancer in high-risk patients (p = 0.016). In multivariate analysis, screeners were more likely than nonscreeners to think that screening for liver cancer reduced mortality (odds ratio [OR] 1.60, CI 1.09–2.34) and that not screening was a malpractice risk (OR 1.88, CI 1.29–2.75). Screeners were more likely than nonscreeners to order any screening test if it was a quality of care measure (OR 4.39, CI 1.79–10.81). CONCLUSIONS: Despite debate about screening efficacy, many physicians screen for liver cancer. Their screening behavior is influenced by malpractice and quality control concerns. More research is needed to develop better screening tests for liver cancer, to evaluate their effectiveness, and to understand how physicians behave when there is insufficient evidence

A prospective investigation of interleukin-8 levels in pediatric acute respiratory failure and acute respiratory distress syndrome

Abstract Background The association of plasma interleukin-8 (IL-8), or IL-8 genetic variants, with pediatric acute respiratory distress syndrome (PARDS) in children with acute respiratory failure at risk for PARDS has not been examined. The purpose of this study was to examine the association of early and sequential measurement of plasma IL-8 and/or its genetic variants with development of PARDS and other clinical outcomes in mechanically ventilated children with acute respiratory failure. Methods This was a prospective cohort study of children 2 weeks to 17 years of age with acute airways and/or parenchymal lung disease done in 22 pediatric intensive care units participating in the multi-center clinical trial, Randomized Evaluation of Sedation Titration for Respiratory Failure (RESTORE). Plasma IL-8 levels were measured within 24 h of consent and 24 and 48 h later. DNA was purified from whole blood, and IL-8 single nucleotide polymorphisms, rs4073, rs2227306, and rs2227307, were genotyped. Results Five hundred forty-nine patients were enrolled; 480 had blood sampling. Plasma IL-8 levels ranged widely from 4 to 7373 pg/mL. Highest IL-8 levels were observed on the day of intubation with subsequent tapering. Levels of IL-8 varied significantly across primary diagnoses with the highest levels occurring in patients with sepsis and the lowest levels in those with asthma. Plasma IL-8 was strongly correlated with oxygenation defect and severity of illness. IL-8 was consistently higher in PARDS patients compared to those without PARDS; levels were 4–12 fold higher in non-survivors compared to survivors. On multivariable analysis, IL-8 was independently associated with death, duration of mechanical ventilation, and PICU length of stay on all days measured, but was not associated with PARDS development. There was no association between the IL-8 single nucleotide polymorphisms, rs4073, rs2227306, and rs2227307, and PARDS development or plasma IL-8 level. Conclusions When measured sequentially, plasma IL-8 was robustly associated with multiple, relevant clinical outcomes including mortality, but was not associated with PARDS development. The wide range of plasma IL-8 levels exhibited in this cohort suggests that further study into the heterogeneity of this patient population and its impact on individual responses to PARDS treatment is warranted.https://deepblue.lib.umich.edu/bitstream/2027.42/148649/1/13054_2019_Article_2342.pd

Distinguishing Type 2 Diabetes from Type 1 Diabetes in African American and Hispanic American Pediatric Patients

To test the hypothesis that clinical observations made at patient presentation can distinguish type 2 diabetes (T2D) from type 1 diabetes (T1D) in pediatric patients aged 2 to 18.Medical records of 227 African American and 112 Hispanic American pediatric patients diagnosed as T1D or T2D were examined to compare parameters in the two diseases. Age at presentation, BMI z-score, and gender were the variables used in logistic regression analysis to create models for T2D prediction.The regression-based model created from African American data had a sensitivity of 92% and a specificity of 89%; testing of a replication cohort showed 91% sensitivity and 93% specificity. A model based on the Hispanic American data showed 92% sensitivity and 90% specificity. Similarities between African American and Hispanic American patients include: (1) age at onset for both T1D and T2D decreased from the 1980s to the 2000s; (2) risk of T2D increased markedly with obesity. Racial/ethnic-specific observations included: (1) in African American patients, the proportion of females was significantly higher than that of males for T2D compared to T1D (p<0.0001); (2) in Hispanic Americans, the level of glycated hemoglobin (HbA1c) was significantly higher in T1D than in T2D (p<0.002) at presentation; (3) the strongest contributor to T2D risk was female gender in African Americans, while the strongest contributor to T2D risk was BMI z-score in Hispanic Americans.Distinction of T2D from T1D at patient presentation was possible with good sensitivity and specificity using only three easily-assessed variables: age, gender, and BMI z-score. In African American pediatric diabetes patients, gender was the strongest predictor of T2D, while in Hispanic patients, BMI z-score was the strongest predictor. This suggests that race/ethnic specific models may be useful to optimize distinction of T1D from T2D at presentation

Postepidemic Analysis of Rift Valley Fever Virus Transmission in Northeastern Kenya: A Village Cohort Study

RVFV infection causes significant disease in both human and animal populations, resulting in significant agricultural, economic and public health consequences. We conducted a cohort study on residents of a high-risk area to measure human anti-RVFV seroprevalence, to identify risk factors, and to estimate the durability of prior RVFV immunity. One hundred two individuals tested for RVFV exposure before the 2006–2007 RVF outbreak were restudied to determine interval anti-RVFV seroconversion and persistence of humoral immunity since 2006. Ninety-two additional subjects were enrolled from randomly selected households to help identify risk factors for current seropositivity. Seroprevalence in the region was high (23%). 1/85 at-risk individuals restudied in the follow-up cohort had seroconverted since early 2006. 29% of newly tested individuals were seropositive. After adjustment in multivariable logistic models, age, village, and drinking raw milk were significantly associated with RVFV seropositivity. Visual impairment (defined as ≤20/80) was much more likely in the RVFV-seropositive group. Among those with previous exposure, RVFV titers remained at protective levels (>1∶40) for more than 3 years. This study highlights the high seroprevalence among Northeastern Kenyans and the ongoing surge in seroprevalence with each RVF outbreak

A Pilot Study of Lay Health Worker Outreach and Colorectal Cancer Screening Among Chinese Americans

The research team recruited eight Chinese American (seven females, one male) lay health workers (LHWs). They received 12 h of training about colorectal cancer (CRC), its screening, and basic health education techniques. Each LHW were asked to recruit ten participants and conduct two educational sessions. Of the 81 participants recruited, 73 had not received colorectal cancer screening. Their mean age was 63.0 years, and 72.6% were women. Knowledge of colorectal cancer, its causes, and its screening increased significantly. Receipt of first colorectal cancer screening test increased from 0.0% at baseline to 55.7% for fecal occult blood tests, 7.1% for sigmoidoscopy, and 7.1% for colonoscopy. LHW outreach is feasible and may be effective in promoting CRC screening among Chinese Americans
