Spinal lymphoma in a goat.

A 3-year-old Pygmy Wether was presented for chronic hindlimb paralysis. A neurological exam revealed nonambulatory paraplegia with absent deep pain nociception, lack of hindlimb withdrawal reflexes, and paraspinal pain on palpation with T3 to L3 neurolocalization. MRI of the lumbar spine revealed an extensive, dorsal to dorsolateral, severely compressive, heterogeneously contrast-enhancing extradural lesion of the lumbar spine with intervertebral foraminal extension into the surrounding paraspinal musculature. Vertebral bone marrow involvement was also noted in the L5 and L6 vertebrae. A diagnosis of lymphoma was obtained after cytological sampling. This is the first case report describing specific MRI findings (signal characteristics, enhancement pattern, and perilesional changes) in a goat with paraspinal lymphoma.

NAFLD and vitamin D: Evidence for intersection of microRNA-regulated pathways.

Non-alcoholic fatty liver disease (NAFLD) is now the most common cause of chronic liver disease, worldwide. The molecular pathogenesis of NAFLD is complex, involving numerous signalling molecules, including microRNAs (miRNAs). Dysregulation of miRNA expression is associated with hepatic inflammation, fibrosis and hepatocellular carcinoma. Although miRNAs are also critical to the cellular response to vitamin D, mediating regulation of the vitamin D receptor and vitamin D's anti-cancer effects, the role of vitamin-D-regulated miRNAs in NAFLD pathogenesis has been relatively unexplored. Therefore, this review aims to critically assess the evidence for a potential subset of miRNAs that are both dysregulated in NAFLD and modulated by vitamin D. Comprehensive review of eighty-nine human studies identified twenty-five miRNAs found dysregulated in more than one NAFLD study. In contrast, only seventeen studies, including a protocol for a trial in NAFLD, had examined miRNAs in relation to vitamin D status, response to supplementation, or vitamin D in the context of the liver. This paper summarises these data and reviews the biological roles of six miRNAs (miR-21, miR-30, miR-34, miR-122, miR-146, miR-200) found dysregulated in multiple independent NAFLD studies. While modulation of miRNAs by vitamin D has been understudied, integration of the data suggests seven vitamin-D-modulated miRNAs (miR-27, miR-125, miR-155, miR-192, miR-223, miR-375, miR-378) potentially relevant to NAFLD pathogenesis. Our summary tables provide a significant resource to underpin future hypothesis-driven research, and we conclude that the measurement of serum and hepatic miRNAs in response to vitamin D supplementation in larger trials is warranted.

Ultrasonographic diagnosis of a lymphomatous lymph node presumptively infiltrating the ureter causing hydronephrosis in a 3-year-old dog.

A 3-year-old male neutered mixed breed dog was presented for chronic vomiting and diarrhea. Abdominal ultrasound revealed a large amorphous, heterogeneous mass within the left mid to caudal abdomen most consistent with medial iliac lymph node. It appeared to invade the left ureter and extend distally causing ureteral obstruction and hydronephrosis. Concurrent additional ultrasound findings were consistent with metastatic or multicentric neoplasia. Fine needle aspirates of the lymph node and spleen both confirmed large cell lymphoma. These findings present evidence of lymphoma invading directly from an organ into the ureter which has not previously been reported in dogs.

Maternal Informal Learning Experiences that Shape Parenting Practices.

Objective: Current understanding of the linkage between maternal education and parenting practices has largely been informed using a narrow definition of educational attainment-the highest level of education an individual has completed. However, the proximal processes that shape parenting, including informal learning experiences, are also important to understand. Less is known about the informal learning experiences that shape parenting decisions and practices. To this end, we conducted a qualitative inquiry about the informal learning experiences of mothers of children ages 3 to 4 years with the specific goal of understanding how maternal informal learning experiences shape parenting decisions and practices. Design: We conducted interviews with 53 mothers from across the United States who had previously participated in a randomized controlled trial (RCT) of an intervention targeting infant care practices. We recruited a purposive sample of mothers chosen to maximize diversity across educational attainment and adherence to infant care practices targeted in the RCT. Using a grounded theory approach, data were analyzed using an iterative process for organizing codes and themes that mothers identified as informal learning experiences. Results: We identified seven themes representing distinct types of maternal informal learning experiences that impact parenting practices, including: (1) experiential learning during childhood; (2) experiential learning during adulthood; (3) interpersonal interactions including via social media; (4) experiences with non-interactive media sources; (5) informal trainings; (6) beliefs; and (7) current circumstances. Conclusions: Multiple informal learning experiences inform the parenting decisions and practices of mothers with varying levels of formal educational attainment.

Implications of Mothers' Social Networks for Risky Infant Sleep Practices.

OBJECTIVE: To describe the structure of networks in a cohort of mothers and to analyze associations of social network characteristics and norms with infant sleep practices. STUDY DESIGN: We recruited a prospective cohort of mothers with infants <6 months of age from January 2015 to December 2016. Mothers completed a survey about their personal social networks and infant care practices. Latent class analysis identified unobserved network types. Binary statistics and path analysis were performed. RESULTS: Overall, 402 mothers were surveyed. Latent class analysis identified 2 a priori unknown social network types: "exclusive" (restricted) and "expansive." Mothers who were black, younger, unmarried, less educated, and of lower socioeconomic status were more likely to have exclusive networks than expansive networks. Mothers with exclusive networks were more likely to be exposed to the norm of soft bedding (P = .002). Exposure to norms of non-supine infant placement, bedsharing, and soft bedding use within one's network was associated with engaging in these practices (P < .0001 for each). First-time mothers were more likely to pay attention to a non-supine norm and place infants in a non-supine position. Black mothers and first-time mothers were more likely to pay attention to the norm and use soft bedding. CONCLUSIONS: Both the type of networks mothers have and the norms regarding infant sleep practices that circulate within these networks differed by race. Network norms were strongly associated with infant sleep practices and may partially explain the racial disparity therein.

Mothers' Perceptions of the Internet and Social Media as Sources of Parenting and Health Information: Qualitative Study.

BACKGROUND: Traditionally, guidance and support to new parents have come from family, friends, and health care providers. However, the internet and social media are growing sources of guidance and support for parents. Little is known about how the internet and social media are used by parents of young infants and specifically about parental perceptions of the internet and social media as sources of parenting and infant health information. OBJECTIVE: The aim of this study was to explore, using qualitative methods, parental perceptions of the advantages and disadvantages of the internet and social media as sources of parenting and health information regarding their infant. METHODS: A total of 28 mothers participated in focus groups or individual interviews. Probing questions concerning parenting and health information sources were asked. Themes were developed in an iterative manner from coded data. RESULTS: The central themes were (1) reasons that mothers turn to the internet for parenting and health information, (2) cautionary advice about the internet, and (3) reasons that mothers turn to social media for parenting and health information. Mothers appreciated the ability to gather unlimited information and multiple opinions quickly and anonymously, but recognized the need to use reputable sources of information. Mothers also appreciated the immediacy of affirmation, support, and tailored information available through social media. CONCLUSIONS: The internet and social media are rapidly becoming important and trusted sources of parenting and health information that mothers turn to when making infant care decisions.

Inconsistent classification of unexplained sudden deaths in infants and children hinders surveillance, prevention and research: recommendations from The 3rd International Congress on Sudden Infant and Child Death.

This report details the proceedings and conclusions from the 3rd International Congress on Unexplained Deaths in Infants and Children, held November 26-27, 2018 at the Radcliffe Institute at Harvard University. The Congress was motivated by the increasing rejection of the diagnosis Sudden Infant Death Syndrome (SIDS) in the medical examiner community, leading to falsely depressed reported SIDS rates and undermining the validity and reliability of the diagnosis, which remains a leading cause of infant and child mortality. We describe the diagnostic shift away from SIDS and the practical issues contributing to it. The Congress was attended by major figures and opinion leaders in this area from countries significantly engaged in this problem. Four categories (International Classification of Diseases (ICD)-11 categories of MH11, MH12, MH14, PB00-PB0Z) were recommended for classification, and explicit definitions and guidance were provided for death certifiers. SIDS was reframed as unexplained sudden death in infancy or SIDS/MH11 to emphasize that either term signifies the lack of explanation following a rigorous investigation. A distinct category for children over the age of 1 was recommended (MH12). Definitions and exclusions were provided for the alternative categories of accidental asphyxia and undetermined. As recommended, unexplained sudden death in infancy or SIDS on a death certificate will code a unique, trackable entity, accurately reflecting the inability to determine a definitive explanation, while satisfying surveillance needs and reliable identification for research efforts. The conclusions will be submitted to the World Health Organization for inclusion in the upcoming ICD-11.

Characteristics of Infant Deaths during Sleep While Under Nonparental Supervision.

OBJECTIVE: To compare risk factors for infant sleep-related deaths under the supervision of parents and nonparents. STUDY DESIGN: We conducted a secondary analysis of sleep-related infant deaths from 2004 to 2014 in the National Center for Fatality Review and Prevention Child Death Review Case Reporting System. The main exposure was supervisor at time of death. Primary outcomes included sleep position, location, and objects in the environment. Risk factors for parental vs nonparental supervisor were compared using χ2 and multivariable logistic regression models. Risk factors associated with different nonparental supervisors were analyzed using χ2. RESULTS: Of the 10 490 deaths, 1375 (13.1%) occurred under nonparental supervision. Infants who died under nonparental supervision had higher adjusted odds of dying outside the home (OR 12.87, 95% CI 11.31-14.65), being placed prone (OR 1.61, 95% CI 1.39-1.86) or on their side (OR 1.35, 95% CI 1.12-1.62), or being found prone (OR 1.74, 95% CI 1.50-2.02). Among infants who died under nonparental supervision, those supervised by relatives or friends were more often placed on an adult bed or couch for sleep and bed sharing (P < .0001), and to have objects in the sleep environment (P = .01). CONCLUSIONS: Infants who died of sleep-related causes under nonparental supervision were more likely to have been placed nonsupine. Among nonparental supervisors, relatives and friends were more likely to use unsafe sleep environments, such as locations other than a crib or bassinet and bed sharing. Pediatricians should educate parents that all caregivers must always follow safe sleep practices.

The Impact of Health Messages on Maternal Decisions About Infant Sleep Position: A Randomized Controlled Trial.

Sudden infant death syndrome (SIDS) rates in African-Americans are more than twice national rates, and historically, African-American parents are more likely than other groups to place infants prone, even when they are aware of supine sleep recommendations. Prior studies have shown African-Americans have low self-efficacy against SIDS but high self-efficacy against suffocation. This study aimed to determine the impact of a specific health message about suffocation prevention on African-American parental decisions regarding infant sleep position. We conducted a randomized controlled trial of 1194 African-American mothers, who were randomized to receive standard messages about safe sleep practices to reduce the risk of SIDS, or enhanced messages about safe sleep practices to prevent SIDS and suffocation. Mothers were interviewed about knowledge and attitude, self-efficacy and current infant care practices when infants were 2-3 weeks, 2-3 months and 5-6 months old. Analyses of covariance were conducted to estimate the change in knowledge, attitudes and practice in each group, and chi square tests were used to compare sleep position with each variable. Over the first 6 months, the proportion of African-American infants placed supine gradually decreased and was unchanged by enhanced education about SIDS, suffocation risk and sleep safety. While initially high self-efficacy against SIDS and suffocation correlated with supine positioning, by 5-6 months self-efficacy did not correspond to sleep position in either group.

Maternal Attitudes and Other Factors Associated with Infant Vaccination Status in the United States, 2011-2014.

OBJECTIVE: To assess the role of maternal attitudes and other factors associated with infant vaccination status. STUDY DESIGN: Data on reported vaccination status were analyzed from a nationally representative prospective survey of mothers of 2- to 6-month-old infants. Weighted univariate and multiple logistic regression analyses were conducted. Latent profile analysis of mothers reporting nonimmunized infants identified distinct groups, RESULTS: Of 3268 mothers, 2820 (weighted 86.2%), 311 (9.1%), and 137 (4.7%), respectively, reported their infant had received all, some, or no recommended vaccinations for age. Younger infants and infants with younger mothers were more likely to have received no vaccinations. Mothers with neutral and negative attitudes toward vaccination were >3 (aOR 3.66, 95% CI 1.80-7.46) and 43 times (aOR 43.23, 95% CI 20.28-92.16), respectively, more likely than mothers with positive attitudes to report their infants had received no vaccinations. Two subgroups of mothers reporting that their infants had received no vaccinations were identified: group A (52.5%) had less than positive attitudes and less than positive subjective norms about vaccination (ie, perceived social pressure from others); group B (47.5%) had positive attitudes and positive subjective norms. Group A mothers were more likely to be white (76.1% vs 48.3%, P?=?.002), more educated (43.5% vs 35.4% college or higher, P?=?.02), and to exclusively breastfeed (74.9% vs. 27.3%, P?

Differences in Infant Care Practices and Smoking among Hispanic Mothers Living in the United States.

OBJECTIVE: To assess the association between maternal birth country and adherence to the American Academy of Pediatrics safe sleep recommendations in a national sample of Hispanic mothers, given that data assessing the heterogeneity of infant care practices among Hispanics are lacking. STUDY DESIGN: We used a stratified, 2-stage, clustered design to obtain a nationally representative sample of mothers from 32 US intrapartum hospitals. A total of 907 completed follow-up surveys (administered 2-6 months postpartum) were received from mothers who self-identified as Hispanic/Latina, forming our sample, which we divided into 4 subpopulations by birth country (US, Mexico, Central/South America, and Caribbean). Prevalence estimates and aORs were determined for infant sleep position, location, breastfeeding, and maternal smoking. RESULTS: When compared with US-born mothers, we found that mothers born in the Caribbean (aOR 4.56) and Central/South America (aOR 2.68) were significantly more likely to room share without bed sharing. Caribbean-born mothers were significantly less likely to place infants to sleep supine (aOR 0.41). Mothers born in Mexico (aOR 1.67) and Central/South America (aOR 2.57) were significantly more likely to exclusively breastfeed; Caribbean-born mothers (aOR 0.13) were significantly less likely to do so. Foreign-born mothers were significantly less likely to smoke before and during pregnancy. CONCLUSIONS: Among US Hispanics, adherence to American Academy of Pediatrics safe sleep recommendations varies widely by maternal birth country. These data illustrate the importance of examining behavioral heterogeneity among ethnic groups and have potential relevance for developing targeted interventions for safe infant sleep.

Health Messaging and African-American Infant Sleep Location: A Randomized Controlled Trial.

Infant-parent bedsharing increases the risk of SIDS and other sleep-related deaths. Despite AAP recommendations to avoid bedsharing, public health efforts have been unsuccessful in changing behaviors. African-American infants are more than twice as likely to die from SIDS and other sleep-related deaths, and are also twice as likely to bedshare with their parents. Further, African-American parents have a high degree of self-efficacy with regards to preventing infant suffocation, but low self-efficacy with regards to SIDS risk reduction. It is unclear whether messages emphasizing suffocation prevention will decrease bedsharing. To evaluate the impact of specific health messages on African-American parental decisions regarding infant sleep location. We conducted a randomized, controlled trial of African-American mothers of infants. The control group received standard messaging emphasizing AAP-recommended safe sleep practices, including avoidance of bedsharing, for the purposes of SIDS risk reduction. The intervention group received enhanced messaging emphasizing safe sleep practices, including avoidance of bedsharing, for both SIDS risk reduction and suffocation prevention. Participants completed interviews at 2-3 weeks, 2-3 months, and 5-6 months after the infant's birth. 1194 mothers were enrolled in the study, and 637 completed all interviews. Bedsharing, both usually (aOR 1.005 [95 % CI 1.003, 1.006]) and last night (aOR 1.004 [95 % CI 1.002, 1.007]) increased slightly but statistically significantly with infant age (p < 0.001). Receipt of the enhanced message did not impact on sleep location. Maternal belief that bedsharing increased the risk of SIDS or suffocation declined over 6 months (p < 0.001) and did not differ by group assignment. African-American mothers who received an enhanced message about SIDS risk reduction and suffocation prevention were no less likely to bedshare with their infants. CLINICAL TRIALS REGISTRATION: Clinical Trials.gov identifier NCT01361880.

Impact of a Randomized Controlled Trial to Reduce Bedsharing on Breastfeeding Rates and Duration for African-American Infants.

Bedsharing is associated with both increased breastfeeding and increased risk of sudden and unexpected infant deaths. The objective was to determine impact of sleep location and counseling about sleep location on breastfeeding exclusivity and duration in African-Americans. 1194 mothers of newborns were randomized to receive messaging emphasizing either safe sleep practices to reduce SIDS risk or safe sleep practices to prevent SIDS/suffocation. Mothers completed four interviews in the 6 months after delivery. The most common sleep arrangement was roomsharing without bedsharing ("roomsharing"). Duration of any breastfeeding was 6.1 and 5.3 weeks for infants who usually bedshared or roomshared, respectively (p = 0.01). Duration of exclusive breastfeeding was 3.0 and 1.6 weeks for infants who usually bedshared or roomshared, respectively (p < 0.001). Group assignment did not affect breastfeeding duration. The most common sleep arrangement for African-American infants <6 months was roomsharing. An intervention designed to discourage bedsharing did not impact breastfeeding duration.

The Effect of Nursing Quality Improvement and Mobile Health Interventions on Infant Sleep Practices: A Randomized Clinical Trial.

Importance: Inadequate adherence to recommendations known to reduce the risk of sudden unexpected infant death has contributed to a slowing in the decline of these deaths. Objective: To assess the effectiveness of 2 interventions separately and combined to promote infant safe sleep practices compared with control interventions. Design, Setting, and Participants: Four-group cluster randomized clinical trial of mothers of healthy term newborns who were recruited between March 2015 and May 2016 at 16 US hospitals with more than 100 births annually. Data collection ended in October 2016. Interventions: All participants were beneficiaries of a nursing quality improvement campaign in infant safe sleep practices (intervention) or breastfeeding (control), and then received a 60-day mobile health program, in which mothers received frequent emails or text messages containing short videos with educational content about infant safe sleep practices (intervention) or breastfeeding (control) and queries about infant care practices. Main Outcomes and Measures: The primary outcome was maternal self-reported adherence to 4 infant safe sleep practices of sleep position (supine), sleep location (room sharing without bed sharing), soft bedding use (none), and pacifier use (any); data were collected by maternal survey when the infant was aged 60 to 240 days. Results: Of the 1600 mothers who were randomized to 1 of 4 groups (400 per group), 1263 completed the survey (78.9%). The mean (SD) maternal age was 28.1 years (5.8 years) and 32.8% of respondents were non-Hispanic white, 32.3% Hispanic, 27.2% non-Hispanic black, and 7.7% other race/ethnicity. The mean (SD) infant age was 11.2 weeks (4.4 weeks) and 51.2% were female. In the adjusted analyses, mothers receiving the safe sleep mobile health intervention had higher prevalence of placing their infants supine compared with mothers receiving the control mobile health intervention (89.1% vs 80.2%, respectively; adjusted risk difference, 8.9% [95% CI, 5.3%-11.7%]), room sharing without bed sharing (82.8% vs 70.4%; adjusted risk difference, 12.4% [95% CI, 9.3%-15.1%]), no soft bedding use (79.4% vs 67.6%; adjusted risk difference, 11.8% [95% CI, 8.1%-15.2%]), and any pacifier use (68.5% vs 59.8%; adjusted risk difference, 8.7% [95% CI, 3.9%-13.1%]). The independent effect of the nursing quality improvement intervention was not significant for all outcomes. Interactions between the 2 interventions were only significant for the supine sleep position. Conclusions and Relevance: Among mothers of healthy term newborns, a mobile health intervention, but not a nursing quality improvement intervention, improved adherence to infant safe sleep practices compared with control interventions. Whether widespread implementation is feasible or if it reduces sudden and unexpected infant death rates remains to be studied. Trial Registration: clinicaltrials.gov Identifier: NCT01713868.

IMAGING DIAGNOSIS-MAGNETIC RESONANCE IMAGING FEATURES OF A MULTIFOCAL OLIGODENDROGLIOMA IN THE SPINAL CORD AND BRAIN OF A DOG.

An 8-year-old neutered male Toy Poodle was presented with chronic, progressive tetraparesis, and possible seizures. Magnetic resonance images demonstrated an extensive, T1 and T2 hyperintense contrast enhancing mass in the cervical spinal cord. Three nodules were present on the surface of the thalamus, with enhancement most evident on delayed images. A diagnosis of high-grade oligodendroglioma was confirmed with postmortem histopathology and immunohistochemical labeling. Oligodendroglioma should be considered as a differential for T1 hyperintense intraaxial or intramedullary lesions with contrast enhancement. If enhancement is not visualized on postcontrast images, delayed images may be beneficial.

Messaging Affects the Behavior of African American Parents with Regards to Soft Bedding in the Infant Sleep Environment: A Randomized Controlled Trial.

OBJECTIVE: To evaluate the impact of specific health messages on the decisions of African American parents regarding soft bedding use, specifically related to the high degree of self-efficacy that African American parents have with regards to preventing infant suffocation vs low self-efficacy with regards to sudden infant death syndrome (SIDS) risk reduction. STUDY DESIGN: We conducted a randomized, controlled clinical trial of African American mothers of infants. The control group received standard messaging emphasizing safe sleep practices recommended by the American Academy of Pediatrics for the purposes of SIDS risk reduction. The intervention group received enhanced messaging emphasizing safe sleep practices for both SIDS risk reduction and suffocation prevention. Participants completed interviews at 2-3 weeks, 2-3 months, and 5-6 months after the infant's birth. RESULTS: Of 1194 mothers enrolled, 637 completed all interviews. The use of soft bedding both in the past week and last night declined with age (P < .001). Infants in the enhanced group had a lower rate of use of soft bedding in the past week (P = .006) and last night (P = .013). Mothers who received the enhanced message were more likely to state that they avoided soft bedding to protect their infant from suffocation. CONCLUSIONS: African American mothers who receive an enhanced message about SIDS risk reduction and suffocation prevention are less likely to use soft bedding in their infant's sleep environment. TRIAL REGISTRATION: ClinicalTrials.gov: NCT01361880.

Differences in African-American Maternal Self-Efficacy Regarding Practices Impacting Risk for Sudden Infant Death.

Sudden Infant Death Syndrome (SIDS) and other sleep-related deaths, including accidental suffocation, account for ~4000 US deaths annually. Parents may have higher self-efficacy with regards to preventing accidental suffocation than SIDS. The objective of this study was to assess self-efficacy in African-American mothers with regards to safe sleep practices and risk for SIDS and accidental suffocation. As part of randomized clinical trial in African-American mothers of newborn infants, mothers completed a baseline survey about knowledge of and attitudes towards safe sleep recommendations, current intent, self-efficacy, and demographics. Tabular and adjusted, regression-based analyses of these cross-sectional data evaluated the impact of the message target (SIDS risk reduction vs. suffocation prevention) on perceived self-efficacy. 1194 mothers were interviewed. Mean infant age was 1.5 days. 90.8 % of mothers planned to place their infant supine, 96.7 % stated that their infant would sleep in the same room, 3.6 % planned to bedshare with the infant, and 72.9 % intended to have soft bedding in the crib. Mothers were more likely to believe that prone placement (70.9 vs. 50.5 %, p < 0.001), bedsharing (73.5 vs. 50.1 %, p < 0.001), and having soft bedding in the sleep area (78.3 vs. 59.5 %, p < 0.001) increased their infant's risk for suffocation than it did for SIDS. Mothers had higher self-efficacy, viz. increased confidence that their actions could keep their infant safe, with regards to suffocation than SIDS (88.0 vs. 79.4 %, p < 0.001). These differences remained significant when controlled for sociodemographics, grandmother in home, number of people in home, and breastfeeding intention. Maternal self-efficacy is higher with regards to prevention of accidental suffocation in African-Americans, regardless of sociodemographics. Healthcare professionals should discuss both SIDS risk reduction and prevention of accidental suffocation when advising African-American parents about safe sleep practices.

Hazards Associated with Sitting and Carrying Devices for Children Two Years and Younger.

OBJECTIVE: To analyze reported mechanisms of injury and characterize risk factors for infants and young children ≤ 2 years of age who died in sitting and carrying devices. STUDY DESIGN: A retrospective review of deaths involving sitting and carrying devices (car seats, bouncers, swings, strollers, and slings) reported to the US Consumer Product Safety Commission between 2004 and 2008. RESULTS: Of the 47 deaths analyzed, 31 occurred in car seats, 5 in slings, 4 each in swings and bouncers, and 3 in strollers. The reported elapsed time between the last time a child was seen by a caregiver and found deceased varied greatly, with a mean of 26 minutes in slings; 32 minutes in strollers; 140 minutes in car seats; 150 minutes in bouncers; and 300 minutes in swings. The cause of death was asphyxiation in all cases except one. Fifty-two percent of deaths in car seats were attributed to strangulation from straps; the others were attributed to positional asphyxia. CONCLUSION: Infants and children 2 years of age and younger should be properly restrained and not be left unsupervised in sitting and carrying devices. Car seats should not be used as sleeping areas outside of the vehicle, and children should never be in a car seat with unbuckled or partially buckled straps. Infants in slings should have their faces visible and above the edge of the sling, should not have their faces covered by fabric, and their chins should not be compressed into their chests.

Frequent vaccination missed opportunities at primary care encounters contribute to underimmunization.

OBJECTIVE: To examine missed opportunities to administer an eligible vaccination (MOs) and their contribution to underimmunization in contemporary pediatric practices. STUDY DESIGN: This study was a retrospective analysis from 42 diverse pediatric practices located throughout the US. Medical records of 50 randomly selected children 3-18 months of age per practice were reviewed in Spring 2013. Immunization status for age and MOs were assessed as of each encounter and as of March 1, 2013. RESULTS: Of 2076 eligible patients, 72.7% (95% CI 67.6-77.9) were up-to-date with receipt of standard vaccines. Most children (82.4%; 95% CI 78.3-85.9) had at least 1 MO, and 37.8% (95% CI 30.0-46.2) had at least one MO to administer an overdue vaccination. After adjustment, risk of underimmunization was 3.5 times greater for patients who had ever experienced an MO for an overdue vaccination compared with those who had not (adjusted relative risk = 3.5; 95% CI 2.8-4.3). If all age-appropriate vaccinations had been administered at the last recorded encounter, 45.5% (95% CI 36.8-54.5) of the underimmunized patients would have been up to date at the time of assessment. CONCLUSION: MOs were common and contributed substantially to underimmunization in this contemporary sample of diverse primary care practice settings.
