Communal mastery and associations with depressive and PTSD symptomatology among urban trauma-exposed women.

Objective: Racial and ethnic minority women from low-resource urban communities experience disproportionately high rates of trauma exposure. Higher rates of lifetime trauma exposure are strongly associated with subsequent psychological sequela, specifically depression and posttraumatic stress disorder (PTSD). Communal mastery is the ability to cope with challenges and achieve goals by being closely interconnected with friends, family, and significant others. Yet, it is unknown if communal mastery is protective specifically against PTSD and depressive symptoms. Method: Participants (N = 131) were Black and Latina women (88.5% Black, mean monthly income: < $750) recruited from an urban outpatient obstetric-gynecological clinic at an academic medical center. Participants completed an online questionnaire that assessed trauma history, PTSD and depressive symptoms, types of individualistic coping, social support, and communal mastery. Results: Hierarchical multiple regression models demonstrated that communal mastery is uniquely associated with fewer PTSD symptoms (ß = -.23, p = .003). More severe trauma history, more use of passive coping skills, and poorer social support were also significantly associated with PTSD symptoms, explaining over half of the variance in PTSD symptoms. Although significantly correlated, communal mastery was not uniquely associated with fewer depressive symptoms (ß = -.13, p = .201). Conclusions: These findings suggest that connectedness as assessed through communal mastery serves as an important shield against the effects of traumatic stress for Black and Latina women. Future research would benefit by exploring interventions that aim to increase communal mastery in order to help highly trauma-exposed racial and ethnic minority women in low-resource environments.

Racial and ethnic disparities of sudden unexpected infant death in large US cities: a descriptive epidemiological study.

BACKGROUND: Sudden unexpected infant death (SUID) accounts for ~ 3400 deaths per year in the USA, and minimal progress has been made in reducing SUID over the past two decades. SUID is the sudden death of an infant that has occurred as a result of accidental suffocation in a sleeping environment, SIDS (sudden infant death syndrome), or from an unknown cause of death. Nationally, non-Hispanic Black (NHB) infants have twice the risk of SUID compared to non-Hispanic White (NHW) infants. In Chicago, this disparity is greatly magnified. To explore whether this disparity is similarly seen in other large cities, we analyzed SUIDs by race and ethnicity for a seven-year period from the 10 most populous US cities. SUID case counts by race and ethnicity were obtained for 2011-2017 from the 10 most populous US cities based on 2010 census data. For each city, we calculated average annual SUID rates (per 1000 live births) by race and ethnicity, allowing calculation of disparity rate ratios. FINDINGS: Nationally, from 2011 through 2017, there were 0.891 SUIDs per 1000 live births, with a rate of 0.847 for NHWs, 1.795 for NHBs, and 0.522 for Hispanics. In most study cities, the NHB and Hispanic SUID rates were higher than the corresponding national rate. Hispanic SUID rates were higher than NHW rates in 9 of the 10 largest cities. In every study city, the NHW SUID rate was lower than the national NHW rate. In Chicago, NHB infants had a SUID rate 12.735 times that of NHW infants. CONCLUSION: With few exceptions, the 10 largest US cities had higher NHB and Hispanic SUID rates, but lower NHW SUID rates, compared to the corresponding rates at the national level. Unlike the national pattern, Hispanic SUID rates were higher than NHW rates in 9 of the 10 largest cities. Prevention is currently hampered by the lack of detailed, accurate, and timely information regarding the circumstances of these tragic deaths. A national SUID surveillance system would allow greater understanding of the factors that lead to this disproportionately distributed and enduring cause of infant death.

Collaborating to Advance Health Equity for Families with Newborns Through Public-Private Partnerships.

This paper describes a health equity-focused partnership between an academic health center and a large metro public health department aimed at improving health care delivery in the postpartum period to reduce maternal-infant mortality. We describe our experience launching Family Connects Chicago at one of four Chicago pilot hospitals across the planning, implementation, and evaluation phases. Key sustainability factors are discussed including cooperative data-sharing, shared funding mechanisms, ongoing engagement strategies across teams, shared leadership, and interprofessional collaboration models. We share implementation strategies to overcome challenges including the commitment of a diverse interprofessional team, a focus on mutual, clear goals, an understanding of shared responsibility and accountability, shared resources, and frequent, open, and honest communication. Successful outcomes including over 1,500 virtual and in-home visits over the first 22 months highlight the need for operational best practice blueprints for meaningful and productive public-private partnerships promoting health equity.

A firm recommendation: measuring the softness of infant sleep surfaces.

BACKGROUND: Approximately 3600 sudden unexpected infant deaths (SUID) occur annually in the United States, and a quarter of SUIDs are caused by unintentional suffocation and strangulation in bed, with soft bedding use being a significant risk factor. Therefore, The American Academy of Pediatrics (AAP) recommends infants sleep on a "firm" surface, though neither an objective definition nor national standard has been established. The purpose of this study is to report on the performance of a device that measures mattress softness and to provide quantitative values of softness for various infant sleep surfaces. METHODS: In collaboration with the authors and a national child product safety organization (Kids in Danger), University of Michigan engineering students designed and validated a device that measures the vertical depression (softness) of a simulated 2-month-old's head on a sleep surface. A total of 17 infant sleep surfaces - 14 household surfaces and 3 hospital mattresses - were measured between April 2019 and January 2020. The average softness of each surface was calculated. Surfaces were also measured with soft bedding, which included an infant fleece blanket, and firm and soft pillows. RESULTS: The average softness for the 14 household sleep surfaces ranged from 7.4-36.9 mm. The 2019 cribette playard and the 2018 infant spring had similar softness (21 mm) as the 2018 and 2019 adult foam and 2015 sofa. An infant's fleece blanket folded once added an additional 2.3-6.5 mm of softness, folded twice added 4.8-11.6 mm, and folded three times added 11-21.8 mm. Using a firm pillow added 4.0-20.9 mm of softness while using a soft pillow added 24.5-46.4 mm. The softness for the 3 hospital sleep surfaces ranged from 14 to 36.9 mm, with the infant bassinet being the firmest and the pediatrics mattress being the softest. CONCLUSIONS: We found a wide range of softness among sleep surfaces, with some infant mattresses as soft as some adult mattresses. Adding blankets and pillows to mattresses measurably increased softness. Quantifying sleep surface softness will advance our understanding of how softness relates to SUID risk. We hope this new information will further inform safe infant sleep recommendations and improve mattress safety standards nationally.

Making Microwave Oven Doors Child Resistant to Protect Young Children From Severe Scalds.

Most severe child scalds in the United States involve food and beverages. The wide variety of burn mechanisms, however, makes prevention challenging. Over the past 15 years, we have worked toward protecting young children from 1 specific mechanism: children opening microwave oven doors themselves and spilling the heated contents, resulting in often severe scalds. In our published research, we documented the frequency and severity of these cases and the vulnerability of young toddlers to be burned in this way. We have presented our findings and ideas for prevention at multiple national meetings and enlisted college engineering students to design microwave doors that would thwart a young child from opening them. In 2017, we became active members of a national task group convened by Underwriters Laboratories to address this issue, and two authors became voting members on the Underwriters Laboratories Standards Technical Panel for microwave ovens. We worked with microwave manufacturers and others for >1 year to address concerns of the industry, including those related to potential impacts on older adults. This effort resulted in the task group proposing a change in the standard, requiring "two distinct actions" to open the door of a microwave oven. On September 17, 2018, the panel voted to pass the measure, which will require child-resistant doors for all new microwave ovens in 2023. This report highlights how research can inform and support child injury prevention advocacy. Children will now be protected from this type of scald as microwaves with child-resistant doors replace current models.

You can have your breastmilk and safe sleep too: a preliminary analysis of infant safe sleep data in a Midwestern home visiting program.

BACKGROUND: Sudden unexpected infant death (SUID) accounted for approximately 3700 infant deaths in the US in 2015. SUID risk factors include prone sleeping, bed-sharing, soft bedding use, and maternal smoking. Infant safe sleep data in at-risk communities are difficult to obtain and home visiting programs can add to what we know. This study's purpose is to determine how often caregivers enrolled in home visiting programs provide safe sleep environments for their infants in relation to breastfeeding status and tobacco use. METHODS: Female caregivers in at-risk communities were prospectively enrolled in Midwestern home visiting programs. Those that had infants < 365 days old and completed a safe sleep survey between October 1, 2016 and May 18, 2017 were included. Caregivers' responses (always, sometimes, or never) to three safe sleep questions were compared by breastfeeding status, caregiver tobacco use, and household tobacco use using Pearson's chi-squared or Fisher's exact test. RESULTS: The characteristics of the 289 eligible female caregivers included 120 (42%) ≤ 21 years old, 137 (47%) black, 77 (27%) breastfeeding, and 60 (22%) with household tobacco use. Two hundred forty-six (85%) caregivers always placed infants in the supine position, 148 (51%) never bed-shared, and 186 (64%) never used soft bedding. Ongoing breastfeeding caregivers never bed-shared more often than those who never breastfed or weaned (66% vs. 53% vs. 39%, p = 0.003). Households with tobacco use placed infants in the supine position less (75% vs. 88%, p = 0.03), bed-shared more (62% vs. 44%, p = 0.04), and used soft bedding more (50% vs. 32%, p = 0.004) relative to those without tobacco use. CONCLUSIONS: In this group of at-risk young mothers, those who breastfed bed-shared less than mothers who were not breastfeeding; this finding has implications toward reducing the SUID risk in similar populations. This study also demonstrated that infants living with a tobacco user are less likely to be sleeping safely. This suggests that a multifaceted approach to safe sleep counseling may be needed.

Not child's play: National estimates of microwave-related burn injuries among young children.

BACKGROUND: Previous studies have shown that children as young as 18 months can open a microwave and remove its contents causing sometimes severe scalds. Although this mechanism may be uniquely preventable by an engineering fix, no national estimate of this type of child burn injury has been reported. METHODS: We analyzed the Consumer Product Safety Commission's National Electronic Injury Surveillance System data on emergency department-treated microwave-related burn injuries from January 2002 through December 2012 in children aged 12 months to 4 years. Based on the narrative description of how the injury occurred, we defined a case as a burn with a mechanism of either definitely or probably involving a child himself or herself opening a microwave oven and accessing the heated contents. National estimates of cases and their characteristics were calculated. RESULTS: During the 11 years studied, an estimated 10,902 (95% confidence interval, 8,231-13,573) microwave-related burns occurred in children aged 12 months to 4 years. Of these, 7,274 (66.7%) (95% confidence interval, 5,135-9,413) were cases of children burned after accessing the contents of the microwave themselves. A total of 1,124 (15.5%) cases required hospitalization or transfer from the treating emergency department. Narratives for children as young as 12 months described the child himself or herself being able to access microwave contents. The most commonly burned body parts were the upper trunk (3,056 cases) and the face (1,039 cases). The most common scalding substances were water (2,863 cases), noodles (1,011 cases), and soup (931 cases). CONCLUSION: The majority of microwave-related burns in young children occur as a result of the child himself or herself accessing the microwave and removing the contents. More than 600 young children are treated in US emergency departments annually for such burns. Children as young as 12 months sustained burns caused by this mechanism of injury. These burns could be prevented with a redesign of microwaves to thwart young children from being able to open the microwave oven door. LEVEL OF EVIDENCE: Epidemiologic study, level III.

Design of non-nucleoside inhibitors of HIV-1 reverse transcriptase with improved drug resistance properties. 2.

HIV-1 nonnucleoside reverse transcriptase inhibitors (NNRTIs) are part of the combination therapy currently used to treat HIV infection. The features of a new NNRTI drug for HIV treatment must include selective potent activity against both wild-type virus as well as against mutant virus that have been selected by use of current antiretroviral treatment regimens. Based on analogy with known HIV-1 NNRTI inhibitors and modeling studies utilizing the X-ray crystal structure of inhibitors bound in the HIV-1 RT, a series of substituted 2-quinolones was synthesized and evaluated as HIV-1 inhibitors.

Novel benzophenones as non-nucleoside reverse transcriptase inhibitors of HIV-1.

GW4511, GW4751, and GW3011 showed IC50 values < or =2 nM against wild type HIV-1 and <10 nM against 16 mutants. They were particularly potent against NNRTI-resistant viruses containing Y181C-, K103N-, and K103N-based double mutations, which account for a significant proportion of the clinical failure of the three currently marketed NNRTIs. The antiviral data together with the favorable pharmacokinetic data of GW4511 suggested that these benzophenones possess attributes of a new NNRTI drug candidate.

Preventing unintentional scald burns: moving beyond tap water.

OBJECTIVE: The goal was to examine in detail the mechanisms of significant scald burns among children <5 years of age, to discover insights into prevention. METHODS: Medical records for children <5 years of age who were admitted with scald burns between January 1, 2002, and December 31, 2004, were identified through the University of Chicago Burn Center database. Demographic data and details of the circumstances and mechanisms of injury were extracted from the medical records. RESULTS: Of 640 admissions to the University of Chicago Burn Center during the 3-year study period, 140 (22%) involved children <5 years of age with scald burns. Of the 137 available charts reviewed, 118 involved unintentional injuries. Of those unintentional injuries, 14 were tap water scalds and 104 were non-tap water scalds. Of the non-tap water scalds, 94 scalds (90.4%) were related to hot cooking or drinking liquids. Two unexpected patterns of injury were discovered. Nine children (8.7%) between the ages of 18 months and 4 years were scalded after opening a microwave oven and removing the hot substance themselves. Seventeen children (16.3%) were scalded while an older child, 7 to 14 years of age, was cooking or carrying the scalding substance or supervising the younger child. CONCLUSIONS: Current prevention strategies and messages do not adequately address the most common mechanisms of scald injury requiring hospitalization. Easy access to a microwave oven poses a significant scald risk to children as young as 18 months of age, who can open the door and remove the hot contents. An engineering fix for microwave ovens could help protect young children from this mechanism of scalding. Involvement of older children in a subset of scald injuries is a new finding that may have prevention implications.
