Hospital admissions can be difficult for patients with autism spectrum disorder (ASD). We created an autism-specific care plan (ACP) to help improve the hospital experience for patients with ASD, and ...we tested feasibility and acceptability and compared the experience of care for children with and without an ACP.
We performed a nonrandomized, retrospective chart review of all patients with ASD and a hospital admission from January 2013 to December 2013 (n = 142) to determine feasibility of the intervention. We then mailed surveys to all 142 families to measure experience with the ACP and to compare experience of care in those who did and did not have an ACP. Using multivariable linear regression we assessed the association of experience of care with ACP use while adjusting for covariates.
The ACP was well tolerated by parents and used frequently by staff. Compared with parents who did not use the ACP, parents who used the ACP reported a better experience relating to their general hospital experience (B = 1.48, P < .001) and staff attention to their child's ASD-specific needs (B = 3.07, P < .001).
According to this pilot study, care plans are feasible and hold promise to improve the experience of care for children with ASD and their families in the hospital setting.
Objective To characterize adverse events (AEs) after hepatitis A vaccines (Hep A) and hepatitis A and hepatitis B combination vaccine (Hep AB) in pregnant women reported to the Vaccine Adverse Event ...Reporting System (VAERS), a spontaneous reporting surveillance system. Study Design We searched VAERS for AEs reports in pregnant women who received Hep A or Hep AB from Jan. 1, 1996-April 5, 2013. Clinicians reviewed all reports and available medical records. Results VAERS received 139 reports of AEs in pregnant women; 7 (5.0%) were serious; no maternal or infant deaths were identified. Sixty-five (46.8%) did not describe any AEs. For those women whose gestational age was available, most were vaccinated during the first trimester, 50/60 (83.3%) for Hep A and 18/21 (85.7%) for Hep AB. The most common pregnancy-specific outcomes following Hep A or Hep AB vaccinations were spontaneous abortion in 15 (10.8%) reports, elective termination in 10 (7.2%), and preterm delivery in 7 (5.0%) reports. The most common nonpregnancy specific outcome was urinary tract infection and nausea/vomiting with 3 (2.2%) reports each. One case of amelia of the lower extremities was reported in an infant following maternal Hep A immunization. Conclusion This review of VAERS reports did not identify any concerning pattern of AEs in pregnant women or their infants following maternal Hep A or Hep AB immunizations during pregnancy.
In June 2002, the Food and Drug Administration received reports of bacterial meningitis in patients with cochlear implants for treatment of hearing loss. Implants that included a positioner (a wedge ...inserted next to the implanted electrode to facilitate transmission of the electrical signal by pushing the electrode against the medial wall of the cochlea) were voluntarily recalled in the United States in July 2002.
We identified patients with meningitis and conducted a cohort study and a nested case-control investigation involving 4264 children who had received cochlear implants in the United States between January 1, 1997, and August 6, 2002, and who were less than six years of age when they received the implants. We calculated the incidence of meningitis in the cohort and assessed risk factors for meningitis among patients and among 199 controls, using data from interviews with parents and abstracted from medical records.
We identified 26 children with bacterial meningitis. The incidence of meningitis caused by Streptococcus pneumoniae was 138.2 cases per 100,000 person-years--more than 30 times the incidence in a cohort of the same age in the general U.S. population. Postimplantation bacterial meningitis was strongly associated with the use of an implant with a positioner (odds ratio, 4.5 95 percent confidence interval, 1.3 to 17.9, with adjustment for medical, surgical, and environmental factors) and with the joint presence of radiographic evidence of a malformation of the inner ear and a cerebrospinal fluid leak (adjusted odds ratio, 9.3 95 percent confidence interval, 1.2 to 94.5). The incidence of meningitis among patients who had received an implant with a positioner remained higher than the incidence among those whose implants did not have a positioner for the duration of follow-up (24 months from the time of implantation).
Parents and health care providers should ensure that all children who receive cochlear implants are appropriately vaccinated and are then monitored and treated promptly for any bacterial infections after receiving the implant.
Purpose
The purposes of this study were to evaluate the frequency with which emergency physicians involved in residency leadership disclose potential malignancy risks from computed tomography (CT), ...assess comfort with these discussions, and evaluate factors influencing risk disclosure.
Methods
We surveyed emergency medicine residency program directors and associate/assistant directors. Primary outcome was the proportion who “almost always” or “most of the time” discussed potential risks.
Results
Two hundred and seventy-four (50.6%) of 542 eligible physicians responded. There were 82.1% (95% CI 76.8%, 86.6%) who reported almost always or most of the time discussing potential risks for patients ≤18 years; proportions for adults 19–40, 41–65, and >65 years were 50.6% (95% CI 44.4, 56.7%), 20.7% (95% CI 16.0, 26.0%), and 5.2% (95% CI 2.9, 8.5%), respectively (test for trend,
p
< 0.001). The proportion reporting being “extremely” or “very” comfortable discussing risks was 57.1% (95% CI 51.1, 63.2%). Patient/family CT request that the physician felt was not indicated was of “very high” or “high” importance for driving risk discussions in 86.4% of respondents. For 75.5%, patient/family query about radiation risks was of “high” or “very high” importance. Among 57.4% of respondents, the patient being elderly and/or having a reduced life expectancy was of “high” or “very high” importance in the decision not to discuss risk.
Conclusions
Emergency physicians involved in residency leadership report frequently disclosing potential malignancy risks from CT at frequencies inversely proportional to patient age. About half are comfortable with discussions, and many discussions are driven by patient requests. Opportunities exist to optimize and standardize emergency department CT radiation risk disclosure practices.
Little is known about the long-term health effects of coalmine fire smoke exposure. The 2014 Hazelwood coalmine fire event in southeast Australia released smoke into surrounding areas for 6 weeks.
We ...aimed to investigate whether individual-level exposure to coalmine fire-related PM
was associated with a long-term increase in ambulance attendances following a coalmine fire event.
A total of 2223 residents from the most exposed town of Morwell were assessed for ambulance attendances after the Hazelwood event from April 1, 2014 to December 31, 2017. PM
exposure was estimated for each individual using participant self-reported location diary data during the event and modelled PM
concentrations. Recurrent event survival analysis was used to evaluate the relationship between PM
exposure and ambulance attendances.
For each 10 μg/m
increase in mean coalmine fire-related PM
exposure, there was a 10% (adjusted hazard ratio HR:1.10, 95%CI:1.03-1.17) increase in the overall risk of ambulance attendances within 3.5 years after the coalmine fire. Exposure to PM
was also associated with increased risk of respiratory (HR: 1.21, 95%CI: 1.02-1.44) and cardiovascular (HR: 1.13, 95%CI: 1.01-1.28) related ambulance attendances.
These results demonstrate that exposure to coalmine fire smoke during the Hazelwood event was associated with a long-term health risk post the fire event, specifically for respiratory and cardiovascular conditions. These findings are important for effective implementation of health care services following future extended coalmine fire PM
events.
Certain chemokine receptors serve as cofactors for HIV type 1 envelope (env)-mediated cell-cell fusion and virus infection of CD4-positive cells. Macrophage tropic (M-tropic) HIV-1 isolates use CCR5, ...and T cell tropic (T-tropic) strains use CXCR4. To investigate the cofactors used by simian immunodeficiency viruses (SIV), we tested four T-tropic and two M-tropic SIV env proteins for their ability to mediate cell-cell fusion with cells expressing CD4 and either human or nonhuman primate chemokine receptors. Unlike HIV-1, both M- and T-tropic SIV envs used CCR5 but not CXCR4 or the other chemokine receptors tested. However, by testing a panel of CCR5/CCR2b chimeras, we found that the structural requirements for CCR5 utilization by M-tropic and T-tropic SIV strains were different. T-tropic SIV strains required the second extracellular loop of CCR5 whereas a closely related M-tropic SIV strain could, like M-tropic HIV-1 strains, use the amino-terminal domain of CCR5. As few as two amino acid changes in the SIV env V3 domain affected the regions of CCR5 that were critical for fusogenic activity. Receptor signaling was not required for either fusion or infection. Our results suggest that viral tropism may be influenced not only by the coreceptors used by a given virus strain but also by how a given coreceptor is used.
Smoking burdens are greatest among underserved patients. Lung cancer screening (LCS) reduces mortality among individuals at risk for smoking-associated lung cancer. Although LCS programs must offer ...smoking cessation support, the interventions that best promote cessation among underserved patients in this setting are unknown. This stakeholder-engaged, pragmatic randomized clinical trial will compare the effectiveness of four interventions promoting smoking cessation among underserved patients referred for LCS. By using an additive study design, all four arms provide standard "ask-advise-refer" care. Arm 2 adds free or subsidized pharmacologic cessation aids, arm 3 adds financial incentives up to $600 for cessation, and arm 4 adds a mobile device-delivered episodic future thinking tool to promote attention to long-term health goals. We hypothesize that smoking abstinence rates will be higher with the addition of each intervention when compared with arm 1. We will enroll 3,200 adults with LCS orders at four U.S. health systems. Eligible patients include those who smoke at least one cigarette daily and self-identify as a member of an underserved group (i.e., is Black or Latinx, is a rural resident, completed a high school education or less, and/or has a household income <200% of the federal poverty line). The primary outcome is biochemically confirmed smoking abstinence sustained through 6 months. Secondary outcomes include abstinence sustained through 12 months, other smoking-related clinical outcomes, and patient-reported outcomes. This pragmatic randomized clinical trial will identify the most effective smoking cessation strategies that LCS programs can implement to reduce smoking burdens affecting underserved populations. Clinical trial registered with clinicaltrials.gov (NCT04798664). Date of registration: March 12, 2021. Date of trial launch: May 17, 2021.
Previous studies report conflicting frequencies of hypertension in cohorts of patients with Williams syndrome (WS). We studied blood pressure (BP) in WS using 24-hour ambulatory BP monitoring. This ...technique reliably measures day- and nighttime BP in a subject's natural environment and provides better prognostic information on long-term risks of hypertension than casual BP determinations. Twenty WS subjects evaluated through a multidisciplinary WS clinic and 35 age and gender-matched controls were studied. We found that WS subjects had significantly higher ambulatory BP than controls. After controlling for age, sex, and weight, the diagnosis of WS added approximately 10 mmHg to mean daytime and nighttime BPs. Hypertension, as defined by elevated mean daytime BP, was present in 40% of WS subjects versus 14% of controls (P < 0.05); among the children studied this difference was even more dramatic with 46% of WS children versus 6% of control children classified as hypertensive (P = 0.01). We also demonstrated normal diurnal BP variation but no evidence of a "white coat" effect or increased BP variability. Interestingly, parental reporting of a history of infantile hypercalcemia was strongly associated with the presence of hypertension (P = 0.008). Our data demonstrate that both children and adults with WS have higher mean BP and higher frequency of hypertension than healthy controls. Thus, elevated BP readings in the office setting should not be dismissed but require more thorough assessment.
