The use of partially quaternized, chloromethylated polystyrene as a covalent scavenger of cholate ion in aqueous media has been demonstrated. The ability of such polymers to scavenge organic anions by covalent as well as by ionic means has important implications in the areas of medicinal and environmental chemistry, which are briefly discussed.

Introduction: Deaths due to drug intoxications in the United States have increased. Public health agencies track the specific intoxicants using death certificate data in order to develop and focus prevention strategies. Criteria used to decide what deaths need toxicological investigation and how these deaths are certified will affect this data. Methods: We retrospectively reviewed the investigative, autopsy, and toxicology reports of 118 fatal intoxications that were certified as "acute opiate intoxication." Results: Of the 113 decedents in whom morphine was detected, 84 were determined to involve heroin. For 61 of 84 heroin deaths, the heroin diagnosis was based upon the detection of diacetylmorphine, 6-acetylmorphine, and/or a lower blood codeine to morphine concentration. For 23 of 84 deaths, the determination was based upon morphine detection and illicit substances and/or paraphernalia at the scene. Of the 61 of 84 heroin deaths diagnosed by direct toxicology results, 33 of the 61 (54%) did not have illicit substances or paraphernalia at the scene. Toxicology identified 33 of 84 (39%) heroin fatalities that would not have been distinguished from morphine intoxication by the scene investigation. Conclusions: The majority of deaths due to opioids can be further classified based upon the toxicological analysis and scene investigation. As heroin deaths may have no illicit substances/paraphernalia at the scene, investigators should not solely base their decision to perform an autopsy/toxicology on the scene absence of illicit drugs/paraphernalia. In our study sample, if toxicology testing were to be only performed when illicit substances/paraphernalia were found at the scene, a high portion of heroin deaths (39%) would have been missed.

Background Sudden Unexpected Infant Death (SUID) is the leading cause of death in the post-neonatal period in the United States. In 2015, Connecticut (CT) passed legislation to reduce the number of SUIDs from hazardous sleep environments requiring birthing hospitals/centers provide anticipatory guidance on safe sleep to newborn caregivers before discharge. The objective of our study was to understand the barriers and facilitators for compliance with the safe sleep legislation by birthing hospitals and to determine the effect of this legislation on SUIDs associated with unsafe sleep environments. Methods We surveyed the directors and/or educators of the 27 birthing hospitals & one birthing center in CT, about the following: 1) methods of anticipatory guidance given to parents at newborn hospital discharge; 2) knowledge about the legislation; and 3) barriers and facilitators to complying with the law. We used a voluntary online, anonymous survey. In addition, we evaluated the proportion of SUID cases presented at the CT Child Fatality Review Panel as a result of unsafe sleep environments before (2011–2015) and after implementation of the legislation (2016–2018). Chi-Square and Fisher’s exact tests were used to evaluate the proportion of deaths due to Positional Asphyxia/Accident occurring before and after legislation implementation. Results All 27 birthing hospitals and the one birthing center in CT responded to the request for the method of anticipatory guidance provided to caregivers. All hospitals reported providing anticipatory guidance; the birthing center did not provide any anticipatory guidance. The materials provided by 26/27 (96%) of hospitals was consistent with the American Academy of Pediatrics (AAP) Guidelines. There was no significant change in rates of SUID in CT before (58.86/100,000) and after (55.92/100,000) the passage of the legislation (p = 0.78). However, more infants died from positional asphyxia after (20, 27.0%) than before the enactment of the law (p < 0.01). Conclusions Despite most CT hospitals providing caregivers with anticipatory guidance on safe sleep at newborn hospital discharge, SUIDs rates associated with positional asphyxia increased in CT after the passage of the legislation. The role of legislation for reducing the number of SUIDs from hazardous sleep environments should be reconsidered.

The majority of childhood deaths investigated by medical examiners and coroners are under the age of one, and medical examiners and coroners are well-versed in the challenges involved in investigating these fatalities. As infants mature to toddlers, there is a paradigm shift with a decrease in both the number of fatalities and the number of undetermined causes of death. A subset of these, however, remain undetermined, causing frustration for both the parents and medical examiner/coroner. In an effort to facilitate a differential diagnosis in these cases, death certificate data from the New York City Office of Chief Medical Examiner for deaths from one to four years of age over a five year period was examined. Of the 230 deaths investigated by the New York City Office of Chief Medical Examiner, the manner was natural in 39%, accident in 32%, homicide in 19%, therapeutic complication in 5%, and undetermined in 5%. Diligent scene investigation and a thorough histologic examination are key components to the investigation. While the lack of a cause of death in a portion of these undetermined deaths is due to limits in current postmortem techniques, a differential diagnosis for these deaths should include channelopathies, seizure disorders, and accidental injuries involving asphyxial mechanisms and inadvertent drug/toxin ingestion.
