Cluster of macrolide-resistant Mycoplasma pneumoniae infections in Illinois in 2012.

Macrolide-resistant Mycoplasma pneumoniae is an increasing problem worldwide but is not well documented in the United States. We report a cluster of macrolide-resistant M. pneumoniae cases among a mother and two daughters.

Recent Iowa trends in sudden unexpected infant deaths: the importance of public health collaboration with medical examiners' offices.

During the winter in 2008, Iowa experienced an increase in sudden unexplained infant deaths (SUIDs). SUIDs and infectious causes of infant deaths generally average 3 monthly (SD = 1.0) in Iowa. However, in January 2008, 9 infant deaths were reported to the Iowa Department of Public Health and the Iowa Office of the State Medical Examiner. Between January and March of 2008, joint investigation of 22 SUIDs was conducted. The investigations required the involvement of multiple medical examiners from various jurisdictions, testing for pathogens at the University Hygienic Laboratory, epidemiologic support from the Iowa Department of Public Health, and consultation with the Centers for Disease Control and Prevention. The preliminary hypotheses for the increase in the infant mortality included viral respiratory disease and/or possible novel respiratory viral infections being the cause. Collaboration between public health and the medical examiner offices resulted in timely assessment of the cases. While no single causative agent was responsible for the increase seen in the number of infant deaths, respiratory pathogens played a role in the deaths of 15 of 22 children.

Health disparities and COVID-19: A retrospective study examining individual and community factors causing disproportionate COVID-19 outcomes in Cook County, Illinois.

Early data from the COVID-19 pandemic suggests that the disease has had a disproportionate impact on communities of color with higher infection and mortality rates within those communities. This study used demographic data from the 2018 US census estimates, mortality data from the Cook County Medical Examiner's office, and testing results from the Illinois Department of Public Health to perform bivariate and multivariate regression analyses to explore the role race plays in COVID-19 outcomes at the individual and community levels. We used the ZCTA Social Deprivation Index (SDI), a measure of ZCTA area level deprivation based on seven demographic characteristics to quantify the socio-economic variation in health outcomes and levels of disadvantage across ZCTAs. Principal findings showed that: 1) while Black individuals make up 22% of Cook County's population, they account for 28% of the county's COVID-19 related deaths; 2) the average age of death from COVID-19 is seven years younger for Non-White compared with White decedents; 3) residents of Minority ZCTA areas were 1.02 times as likely to test positive for COVID-19, (Incidence Rate Ratio (IRR) 1.02, [95% CI 0.95, 1.10]); 1.77 times as likely to die (IRR 1.77, [95% CI 1.17, 2.66]); and were 1.15 times as likely to be tested (IRR 1.15, [95% CI 0.99, 1.33]). There are notable differences in COVID-19 related outcomes between racial and ethnic groups at individual and community levels. This study illustrates the health disparities and underlying systemic inequalities experienced by communities of color.

The utility of video technology and enhanced infection control in reducing COVID-19 disease burden in a custodial setting.

We describe the use of video technology to enhance case interviews, identify COVID-19 contacts, and determine exposures risk within a large juvenile temporary detention center. We created a COVID-19 outbreak management protocol which included the formation of an outbreak management team and enhanced infection control practices using video surveillance. Currently, our institution's positivity rate remains low for both staff and residents largely because of the outbreak management team. Video technology combined with enhanced infection control practices can be a useful technique to reduce COVID-19 infections in custodial settings.

Years of potential life lost secondary to COVID-19: Cook County, Illinois.

The COVID-19 pandemic caused by the SARS-CoV-2 virus has led to substantial morbidity and mortality world-wide. Evidence suggests that ethnic and racial minorities have been disproportionately affected in the United States, particularly within major population centers. In this study, we evaluated the effect of the COVID-19 pandemic in Cook County, Illinois, and found that the rate of years of potential life lost (YPLL) was 4.8 times greater in the most affected racial group (YPLL: 2289/100,000 population in Hispanic people) than in the least affected group (YPLL: 480/100,000 population in Asian people).

Control of measles in a juvenile custodial setting in the wake of the recent US outbreak.

The recent US measles outbreak is the largest since 1992. It is just a matter of time before measles is introduced into a juvenile custodial setting. Are we prepared? Should we be prepared? This short article addresses steps institutional settings should take to prevent the spread of measles in a contained setting.

COVID-19 and the Nigerian correctional service: need for structured data.

Although prisoners are considered a vulnerable population, no data repository currently exists to monitor the COVID-19 incidence in Nigerian prisons. To better understand the impact of COVID-19 within the Nigerian prison system, prisons should develop detailed COVID-19 response protocols, implement enhanced point-of-care testing, and initiate contact tracing with meticulous data collection.

Maternal diabetes mellitus as an independent risk factor for clinically significant retinopathy of prematurity severity in neonates less than 1500g.

BACKGROUND: Retinopathy of prematurity (ROP) is a significant morbidity in preterm babies. Multiple risk factors for severe ROP have been extensively studied, however, only a few studies have included maternal diabetes mellitus (MDM) in their assessment. ROP and diabetic retinopathy are both retinal vascular diseases in which there is leakage and/or neovascularization from damaged retinal vessels. Diabetes may affect ROP development; however, there are conflicting results on the association between MDM and ROP. OBJECTIVE: To determine if MDM is an independent risk factor for clinically significant ROP (ROP > Stage II) in neonates weighing less than 1500g. DESIGN/METHOD: We conducted a retrospective cohort study of neonates weighing <1500g who were delivered or transferred into our institution from 2007 through 2017. Logistic regression was used to analyze the association between severe ROP and MDM. The risks for the different stages of ROP from MDM were compared using chi-square linear trend test. RESULTS: We extracted 883 paired maternal-neonatal data. The mean (standard deviation) gestational age and birthweight were 28.5 (2.9) weeks and 1052.7 (300.9) grams, respectively. Of the 883 mothers, 72 (8.2%) had DM. The incidence of ROP and severe ROP was 42.4% (374/883) and 6.5% (57/883) respectively. The odds ratio comparing MDM and severe ROP was 3.47 [95% CI: 1.51-7.96]; p<0.01). Compared to Stage I, the risk of MDM in infants with ROP increased from 1.49 in Stage II ROP to 2.59 in Stages III&IV. Severe ROP was associated with infant steroid use (OR: 5.92 [95% CI: 2.83-12.38]; p <0.01), sepsis (OR: 2.13 [95% CI: 1.09-4.14]; p = 0.03) chorioamnionitis (OR: 1.90 [95% CI: 1.03-3.50]; p = 0.04), and maternal steroid use (OR: 0.51 [95% CI: 0.32-0.79]; p<0.01). CONCLUSION: Maternal diabetes is associated with ROP and the strength of association increased with increasing severity of ROP.

Interventions to improve liver enzyme screening testing in obese patients aged <18 years in a public hospital, Chicago, IL, 2017-2018.

INTRODUCTION: Our study objective was to determine the health care provider liver enzyme screening testing (LEST) rates in obese pediatric patients at risk for nonalcoholic fatty liver disease (NAFLD), with the goal of improving NAFLD LEST after specific system-wide provider intervention. METHODS: We conducted a bi-phased retrospective electronic medical record review of health care practitioner encounters to determine LEST in overweight/obese (body mass index≥25) patients between ages 2 and 18 years in our outpatient clinics. Intervention activities included lectures to staff and residents, fliers distributed to providers, monthly email reminders, and computer stickers placed on all terminals. From both phases, samples of simple random samples were drawn from the selected electronic medical records and reviewed for LEST screening; after intervention from this pool of patients, a random sample was chosen for LEST rate analysis. LEST rates were calculated per 100 patient encounters. RESULTS: We screened 2,979 and 2,634 pre and postintervention pediatric encounters from which we obtained a simple random sample of patients for LEST analysis. Overall of the 264 preintervention patients, 65 (24.4%) patients received LEST translating to 24/100 encounters. Of the 65 who received screening, 53 (81%) were classified as overweight/obese. Screening rate was higher for overweight/obese patients (32/100 encounters), when compared with normal weight patients' crude OR 3.8 (11/100 encounters; 95% CI: 1.9-7.6, P<0.005). Of the 242 postintervention patients, 70 (28%) received LEST translating to 28/100 encounters; of these, 58 (82%) were classified as overweight/obese with a rate of 42/100 encounters compared with 11/100 encounters for normal weight patients' crude OR 5.5 (95% CI: 2.8-7.5, P<0.005). CONCLUSION: Obesity is a significant risk factor for NAFLD; one in four obese pediatric patients had LEST. Additional health care practitioner education and interventions are needed to improve LEST to prevent long-term complications such as liver cirrhosis or failure.

A fracture, a family, legal entanglement, expensive investigation, and a familiar disease.

Osteogenesis imperfecta can be commonly mistaken for child abuse because of similar pattern of injuries. AA is a 3-week-old baby who presented to our emergency department with excessive crying. Skeletal survey revealed subacute spiral fracture of the right humerus, right posterior eighth and ninth ribs, acute fracture of the left femur, bowing of tibia and femur, and osteopenia. Subsequent geneticist examination and genetic testing noted blue sclera and heterozygosity for a variant of COL1A gene.

Analysis of HIV testing refusal among patients aged less than 21 years in the Pediatric Emergency Department.

HIV testing in the Pediatric Emergency Department (PED) is a novel concept as adolescents, and young adults, use the PED as point of care or first point of contact with the health care system. Our objective was to study the HIV nontesting data and factors that influenced testing decision among patients receiving care in our PED. We designed a survey that inquired about testing acceptance, reasons for rejection, satisfaction with testing conditions, and understanding of the consequence of HIV test results. We approached 500 patients across all shifts in the PED; for analysis, categorical variables were created using demographic data (race, age, ethnicity, marital status, level of education). Forward conditional binary logistic regression was used to explore the effect of various independent predictors on HIV testing rejection with the strength of association measured with adjusted odds ratio (OR), and their 95% CIs. We conducted model fitting by plotting residuals, Hosmer and Lemeshow test statistic, and area under the curve completed using predicted probabilities. We used SPSS Version 25™, Microsoft Excel 2016™ for data preparation and analysis. Of the 500 patients approached, 423 (84.6%) completed the survey, median (interquartile) age of survey participants was 19 (17-20) years, 158 (37.4%) rejected HIV testing, 284 (67.1%) were older than 18 years of age, 200 (47.3%) were males, 154 (36.4%) were white, and 127 (30%) were of Hispanic origin. The most common reason for rejecting HIV was low risk perception declared by 79 (50%) respondents. In multivariate analysis, age <18 years (OR, 3.5; 95% CI, 2.3-5.5, P<0.00) and being Hispanic (OR, 2.5; 95% CI, 1.6-3.8, P<0.00) were significant predictors for respondent nontesting. Hosmer and Lemeshow test was not significant, P=0.42, and area under the curve was 0.67 (95% CI, 0.61-0.76). Respondents, <18 years were more likely to reject HIV testing because of low perception of risk. Program addressing risk perception which emphasizes safe health practices should be developed to reduce HIV transmission.

Impact of vaccine mandate on Tdap vaccination coverage among Illinois students 2014-15.

In response to recent pertussis resurgence, a multi-agency recommendation that students receive a one-time Tdap vaccine was introduced. Post mandate there was sequential increase in the Tdap vaccine uptake in the targeted population.

Vaccine financing in Nigeria: are we making progress towards self-financing/sustenance?

Nigeria has an estimated population of 186 million with 23% of eligible children aged 12-23 months fully immunized. Government spending on routine immunization per surviving infant has declined since 2006 meaning the immunization budget needs to improve. By 2020, Nigeria will be ineligible for additional Global Alliance for Vaccination and Immunization (Gavi) grants and will be facing an annual vaccine bill of around US$426.3m. There are several potential revenue sources that could be utilized to fill the potential funding gap, these are however subject to timely legislation and appropriation of funds by the legislative body. Innovative funding sources that should be considered include tiered levies on tele-communications, airline, hotel, alcohol, tobacco, sugar beverage taxes, lottery sales, crowd-sourcing, optimized federal state co-financing etc. To demonstrate monthly income that will be derived from a single tax revenue source, we modelled using Monte Carlo simulation trials the Communication Service Tax that is being introduced by the National Assembly. We used number of active telephone subscribers, penetration ratio, monthly charges, and percent of immunization levy as model scenario inputs and dollars generated monthly as output. The simulation generated a modest mean (SD) monthly amount of $3,649,289.38 ($1,789,651); 88% certainty range $1,282,719.90 to $7,450,906.26. The entire range for the simulation was $528,903.26 to $7,966,287.26 with a standard error of mean of $17,896.52. Sensitivity analysis revealed that percentage of immunization levy contributed 97.9 percent of the variance in the model, number of active subscribers and charges per month contributed 1.5%, and 0.6% respectively. Our modest simulation analysis demonstrated the potential to raise revenue from one possible tax source; when combined, the revenue sources will potentially surpass Nigeria's long-term financing needs. The ROI of vaccine should supersede all other considerations and prompt urgent activities to cover the impending finance coverage gap.

Joinpoint regression analysis of pertussis crude incidence rates, Illinois, 1990-2014.

Pertussis incidence has increased in recent years; we obtained incidence data from 1990-2014 from the Illinois Department of Public Health Web site. We analyzed the crude incidence rates using Joinpoint regression software. Four joinpoints were observed (2001, 2004, 2007, and 2012). Disease modeling can be used for disease control and planning by extrapolating the trend in the incidence data and applying to annual population estimates.

Review and modelling of malaria crude incidence rate in a low incidence population, Illinois 1990 to 2013.

The highest risk of imported malaria in Illinois is associated with travel to countries of origin by immigrants to visit family and friends. We used Join point regression to analyze Malaria crude incidence rate (mCIR) trend from 1990 through 2013. We found join point regression a useful way to summarize mCIR trends because it connected the linear line segments over a fixed time interval (annual) and allowed characterization of the trends using the Annual Percent Change.
