RESUMEN

OBJECTIVE: To develop a dyadic-centered framework focused on clinical care, surveillance, and research for birthing persons with opioid use disorder (OUD) and their infants and children. STUDY DESIGN: Between February and March 2023, an analysis was conducted within the US Department of Health and Human Services (HHS) of activities directed at opioid-exposed birthing persons and their infants and children (the dyad) to identify: 1) number of activities, stratified by type and 2) characteristics across health and supportive activities that serve the dyad vs birthing persons or infants and children individually. Descriptive and thematic analyses were used to assess quantity and characteristics of fiscal year 2023-2024 activities aggregated across eleven HHS agencies. RESULTS: Of 181 activities examined, 75 met inclusion criteria specific to serving birthing persons with OUD and opioid-exposed infants and children. Sixty-two percent of activities were dyad focused. Five categories of dyadic activities were identified: research (45%), education and training (28%), health and supportive services (21%), surveillance (4%), and quality improvement (2%). Eight specific characteristics were key to dyadic activities: a life course and generational approach, emphasis on relationship, dyadic outcomes, service wraparound, payment structures supporting dyadic care, data linkage, and social determinants of health. CONCLUSIONS: This analysis of HHS activities directed at birthing persons with OUD and opioid-exposed infants and children showed that most programs had a dyadic focus. Synthesizing elements identified from activities serving the dyad facilitated the development of a dyadic framework integrating clinical care, public health surveillance, and research.

RESUMEN

To improve palivizumab administration in high-risk infants with congenital heart disease to 80% over 2 years at an academic children's heart center. A multidisciplinary team at our institution implemented a series of interventions over a 2-year prior. Pediatric cardiac patients were identified for palivizumab eligibility, and a baseline rate of administration was obtained. A series of communication and documentation-based interventions were implemented over the course of the next 2 years. Palivizumab eligible infants (n = 114) were determined based on guidelines after review of diagnosis code, oxygen saturation, and medications. Doses of palivizumab were tracked via the electronic health record. The primary outcome measures were the rate of monthly palivizumab doses administered per the number of eligible months and the percentage of infants who received at least 80% of eligible doses during the respiratory syncytial virus season. The rate of monthly palivizumab doses increased from 57.6% during the baseline period to 78.4% during the final year of the project (p = 0.02). The percentage of infants who received 80% of eligible doses increased from 42.1 to 60% but was not statistically significant (p = 0.20). Interventions focused on properly identifying and tracking infants eligible for palivizumab treatment significantly increased the rates of administration.

RESUMEN

OBJECTIVE: To standardize the clinical definition of opioid withdrawal in neonates to address challenges in clinical care, quality improvement, research, and public policy for this patient population. STUDY DESIGN: Between October and December 2020, we conducted 2 modified-Delphi panels using ExpertLens, a virtual platform for performing iterative expert engagement panels. Twenty clinical experts specializing in care for the substance-exposed mother-neonate dyad explored the necessity of key evidence-based clinical elements in defining opioid withdrawal in the neonate leading to a diagnosis of neonatal abstinence syndrome (NAS)/neonatal opioid withdrawal syndrome (NOWS). Expert consensus was assessed using descriptive statistics, the RAND/UCLA Appropriateness Method, and thematic analysis of participants' comments. RESULTS: Expert panels concluded the following were required for diagnosis: in utero exposure (known by history, not necessarily by toxicology testing) to opioids with or without the presence of other psychotropic substances, and the presence of at least two of the most common clinical signs characteristic of withdrawal (excessive crying, fragmented sleep, tremors, increased muscle tone, gastrointestinal dysfunction). CONCLUSIONS: Results indicate that both a known history of in utero opioid exposure and a distinct set of withdrawal signs are necessary to standardize a definition of neonatal withdrawal. Implementation of a standardized definition requires both patient engagement and a mother-neonate dyadic approach mindful of program and policy implications.

RESUMEN

OBJECTIVES: Opioid exposed infants born to incarcerated women represent a vulnerable and understudied subset of infants with neonatal abstinence syndrome (NAS). The impact of maternal incarceration on length of stay (LOS) for infants with NAS is unknown. We hypothesized that infants with NAS born to incarcerated women have longer hospitalizations compared to infants with NAS born to non-incarcerated women. METHODS: This is a retrospective cohort study of infants with NAS born between 2011 and 2018 at the primary delivery site for Connecticut's only women's prison. Opioid exposed infants were assessed by Finnegan Scores for withdrawal and received morphine as a first line agent and phenobarbital as a second line agent. LOS was compared using Poisson regression. RESULTS: Of 206 infants identified, 166 were included in the analysis, with 28 born to incarcerated women and 138 to non-incarcerated women. Incarcerated women were more likely to report prenatal alcohol use, 14.3% vs 2.2% p = 0.016 and benzodiazepine use 21.4% vs 7.3% p = 0.032. Infants of incarcerated women were less likely to be fed breast milk at discharge, 3.6% vs 37% p < 0.001. Adjusted mean LOS was longer among infants born to incarcerated women, 18.5 vs 16.6 days (p = 0.009). CONCLUSIONS FOR PRACTICE: Infants with NAS born to incarcerated women in Connecticut had longer LOS, lower rates of being fed breast milk, and different prenatal substance exposures than infants with NAS born to non-incarcerated women. Supporting the maternal-infant dyad until infant discharge may mitigate the potential negative impact of maternal incarceration on the care of infants with NAS.

RESUMEN

Ionizing radiation exposure is a necessary risk entailed during congenital cardiac catheterizations. The congenital catheterization lab at Yale New Haven Children's Hospital employed quality improvement strategies to minimize radiation exposure in this vulnerable population. In two phases, we implemented six interventions, which included adding and utilizing lower fluoroscopy and digital angiography (DA) doses, increasing staff and physician radiation awareness, focusing on tighter collimation, and changing the default fluoroscopy and DA doses to lower settings. Post-intervention data were collected prospectively for all procedures in the congenital catheterization lab and compared to pre-intervention radiation data collected retrospectively. Radiation exposure was measured in total air kerma (mGy), dose area product per body weight (DAP/kg) (µGy m2/kg), and fluoroscopy time (min). Data were collected for a total of 312 cases. In considering all procedures, the DAP/kg decreased by 67.6% and air kerma decreased by 63%. Fluoroscopy time did not change over the study period. Significant decreases in radiation exposure (DAP/kg) by procedure type were seen for atrial septal defect, patent ductus arteriosus, and transcatheter pulmonary valve procedures with a 45%, 42% and 83% decrease, respectively. Air kerma decreased significantly for ASD and PDA procedures with an 80% and 72% decrease, respectively. When compared to national benchmarks, the median DAP/kg and air kerma for these procedures are lower at our institution. The decreases continue to be sustained 2 years post-interventions. Systems-based interventions can be readily implemented in the congenital cardiac catheterization lab with dramatic and sustainable radiation dose reduction for patients.

RESUMEN

BACKGROUND: Bronchiolitis is a viral lower respiratory tract infection that causes significant morbidity and mortality in the pediatric population. Viral diagnostic testing (VDT) has been used to identify specific viral pathogens. However, current guidelines suggest that routine use of this testing is not advisable. For children admitted to a children's hospital from the pediatric emergency department (PED), the rate of VDT was 63%, which was higher than the national rate. A quality improvement project was conducted to reduce the use of routine VDT. METHODS: Key drivers of VDT were identified, and interventions, which included staff education about the cost and use of VDT and dissemination of a simplified cohorting policy aimed to eliminate VDT without medical necessity, were implemented through the PED and inpatient unit settings. RESULTS: Between January 2017 and April 2017, VDT use in all non-ICU patients admitted from the PED with bronchiolitis decreased from 63% to 12%. In the same time period, patients with VDT sent from the PED fell from 53% to 14%. A reduction in VDT for patients admitted with asthma exacerbation was also observed-from 24% to 0%-demonstrating early spread of these effects. Cost savings of approximately $8,584 per year in direct supply costs alone was documented. CONCLUSION: Using simple, low-cost interventions, including education and guideline refinement, the rate of VDT use for bronchiolitis was significantly reduced. Further directions for this project include the reduction of routine testing for patients with bronchiolitis who are admitted to the ICU or discharged for outpatient care.

RESUMEN

Polycyclic aromatic hydrocarbon (PAHs) are common soil contaminants of concern due to their toxicity toward plants, animals and microorganisms. The use of indigenous or added microbes (bioaugmentation) is commonly used for bioremediation of PAHs. In this work, the biodegradation rates and changes in the bacterial community structure were evaluated. The enrichment culture was useful for unambiguously identifying members of the soil bacterial community associated with PAH degradation and yielded a low diversity community. No significant difference in the rate of PAH degradation was observed between the microcosm receiving only PAHs or PAHs and bioaugmentation. Moreover, identical matches to the bioaugmentation inoculum were only observed at the initial stages of PAH degradation on day 8. After 22 days of incubation, the substantial degradation of all PAHs had occurred in both microcosms and the PAH contaminated soil had statistically significant increases in Alphaproteobacteria. There were also increases in Betaproteobacteria. In contrast, the PAH contaminated and bioaugmented soil was not enriched in PAH degrading Proteobacteria genera and, instead, an increase from 1.6% to 8% of the population occurred in the phylum Bacteroidetes class Flavobacteria, with Flavobacterium being the only identified genus. In addition, the newly discovered genus Ohtaekwangia increased from 0% to 3.2% of the total clones. These results indicate that the same soil microbial community can give rise to different PAH degrading consortia that are equally effective in PAH degradation efficiency. Moreover, these results suggest that the lack of efficacy of bioaugmentation in soils can be attributed to a lack of persistence of the introduced microbes, yet nonetheless may alter the microbial community that arises in response to PAH contamination in unexpected ways.

RESUMEN

BACKGROUND AND OBJECTIVES: The present study examined the psychometric characteristics of the Neonatal Abstinence Scoring System (NASS; "Finnegan Scale") and the MOTHER NAS Scale (MNS). METHODS: Secondary analysis of data from 131 neonates from the Maternal Opioid Treatment: Human Experimental Research (MOTHER) study, a randomized trial in opioid-dependent pregnant women administered buprenorphine or methadone. RESULTS: Both the NASS and MNS demonstrated poor psychometric properties, with internal consistency (Cronbach's αs) failing to exceed .62 at first administration, peak NAS score, and NAS treatment initiation. CONCLUSIONS: Findings support the need for development of a NAS measure based on sound psychometric principles. SCIENTIFIC SIGNIFICANCE: This study found that two frequently used measures of neonatal abstinence syndrome suffer inadequacies in regard to their basic measurement characteristics.

RESUMEN

Pancreatic cancer is one of the most fatal malignancies due to its advanced stages at the time of presentation. Often, it is only diagnosed when patients present with late-stage complications, such as gastric outlet obstruction (GOO). Many patients experience a poor quality of life due to the side effects of GOO, such as persistent nausea, vomiting, and an inability to tolerate an oral diet, and as such, patients deteriorate quickly after their diagnosis. Because pancreatic cancer is diagnosed at advanced stages, many patients are not surgical candidates, and thus treatment is tailored for palliative measures. With GOO specifically, gastrojejunostomy has been the mainstay of palliative management; however, endoscopic stent placement is a new, innovative, and minimally invasive alternative option. Herein, we present a case of GOO as a complication of pancreatic adenocarcinoma, treated with palliative endoscopic stent placement. Further research is warranted to identify patients who would most benefit from this modality of palliation in the treatment of advanced pancreatic cancer.

RESUMEN

Importance: Although cases of neonatal opioid withdrawal syndrome (NOWS) increased 5-fold in recent years, no study has examined national hospital readmission rates for these infants. Objective: To examine hospital readmissions for infants with and without NOWS. Design, Setting, and Participants: This retrospective cohort study analyzed serial cross-sectional samples of US hospital discharge records from the Nationwide Readmissions Database for calendar years 2016 to 2020. Infants with NOWS were identified using International Classification of Diseases, Tenth Revision, Clinical Modification codes. The data analysis was performed between January 5, 2023, and May 6, 2024. Exposure: Neonatal opioid withdrawal syndrome. Main Outcome and Measures: Survey-weighted logistic regression was used to examine 90-day all-cause and cause-specific hospital readmissions. Multivariable models adjusted for sex, low birth weight, gestational age, multiple gestation, type of insurance, and year of birth. Results: Of the 13 855 246 newborns identified in this weighted analysis, 89 018 (0.6%) were diagnosed with NOWS, of whom 53.8% were male and 81.1% born full-term (>36 weeks gestation). The 90-day all-cause readmission rate was 4.2% for infants with NOWS compared with 3.0% for those without NOWS (P < .001). After risk adjustment, the odds of all-cause readmission were higher among infants with NOWS (adjusted odds ratio [AOR], 1.18; 95% CI, 1.08-1.29). Infants with NOWS had significantly higher odds of readmissions for seizures (AOR, 1.58; 95% CI, 1.01-2.46), failure to thrive (AOR, 1.99; 95% CI, 1.36-2.93), traumatic brain injury (AOR, 2.95; 95% CI, 1.76-4.93), and skull fractures (AOR 3.72; 95% CI, 2.33-5.93). Infants with NOWS had higher odds of receiving a diagnosis of confirmed maltreatment (AOR, 4.26; 95% CI, 2.19-8.27), including for neglect (AOR, 14.18; 95% CI, 5.55-36.22) and physical abuse (AOR, 2.42; 95% CI, 0.93-6.29); however, the latter finding was not statistically significant. Conclusions and Relevance: In this nationally representative cohort study, infants with NOWS were at increased risk of readmission for any cause as well as for trauma and confirmed maltreatment. These findings may in part reflect the dual stressors that mothers with opioid use disorder face in caring for a newborn with NOWS in the context of a substance use disorder and underscore the need for family-based, in-home services that focus concurrently on substance use treatment and parenting support.

RESUMEN

Background: Common bile duct dilatation alone or double duct sign (both CBD and dilated pancreatic duct dilatation) and abnormal liver enzymes are highly predictive of biliary disease. This can be identified on ultrasound (US), CT scan, and/or magnetic resonance cholangiopancreatography (MRCP). Unexplained dilatation on imaging might warrant endoscopic ultrasound (EUS) to identify any occult causes. Supporting literature about the importance of using EUS in these conditions is evolving with no clear evidence-based approach to evaluate asymptomatic dilated ducts.We aim to investigate the diagnostic yield of EUS in unexplained CBD dilatation or double duct sign with normal liver enzymes. Method: A retrospective data analysis was conducted from January 2015 to October 2021 on asymptomatic patients with a dilatated CBD of 7 mm or more and 9 mm if the patient had a cholecystectomy history or double duct sign with normal liver enzymes. Result: 32 EUS procedures were indicated for unexplained dilated CBD or double duct sign on imaging with normal liver enzymes. 23 had CBD dilatation alone (72 %), and 9 had a double duct sign (28 %). 20 of the included patients were females (63 %), and 12 were males (37 %), with a mean age of 63.8 ± 17 and 68.2 ± 14 years old, respectively (p = 0.424). The diagnosis after EUS in CBD dilatation alone showed a yield of 56 % as follow; no pathology in 10 (44 %), sludge in 9 patients (39 %), CBD stone in 3 (13 %), malignant stricture in 1 (4 %) (Fig. 1). On the other hand, EUS in those with double duct signs showed a diagnostic yield of 55 %; no pathology in 4 (45 %), pancreatic head adenocarcinoma in 3 patients (33 %), Biliary stone in one patient, and malignant CBD stricture in one patient (11 % each) (Fig. 2). Conclusion: Unexplained CBD dilatation or Double duct sign on imagining in patients with normal liver enzymes should warrant further investigation with EUS to avoid missing serious pathological conditions such as stones, sludge, stricture, or a mass.

RESUMEN

Introduction: An increased incidence of maternal opioid use disorder (OUD) and neonatal abstinence syndrome (NAS) has prompted recommendations supporting a dyadic approach to care for birthing persons and their infants. However, there are no consensus guidelines outlining how the dyad is clinically defined. Methods: To examine how the opioid-exposed birthing person-infant dyad has been defined for purposes of data collection and research, a literature review applying the RAND/UCLA Appropriateness Method was conducted. Results: The search yielded 320 abstracts, with 110 articles identified as having a dyadic focus. While no articles included a specific definition for the dyad, 33 (30%) contained a descriptive reference to the birthing person-infant dyad. Thematic analysis revealed eight recurring elements characteristic of the dyad: (1) engagement, (2) communication, (3) bonding, (4) attachment, (5) mutual responsiveness, (6) reciprocity, (7) synchrony, and (8) attunement. Integrating these elements revealed the interactional relationship between the opioid-exposed birthing person and infant as the foundational principle that defines the dyad. Discussion: This definition shifts the focus of the opioid-exposed dyad from two individual patient populations to an interactional relationship that has broad applicability for clinical use, public health data collection, and research considerations.

RESUMEN

Introduction: Bronchopulmonary dysplasia (BPD) is a chronic lung disorder affecting many premature infants. Infants with BPD have higher hospital readmission rates due to respiratory-related morbidity. We aimed to increase the rates of outpatient pulmonary follow-up and attendance of premature babies with moderate and severe BPD to above 85% within 6 months. Methods: We conducted a quality improvement project at Yale New Haven Children's Hospital. Key interventions included developing a BPD clinical pathway integrated into the electronic medical record to assist providers in correctly classifying BPD severity, assigning the appropriate International Classification of Diseases, 10th Revision code (P27.1), and providing standardized treatment options. The outcome measures included correct diagnosis and classification of BPD, the percentage of patients with BPD scheduled for pediatric pulmonology appointments within 45 days, and the percentage attending those appointments. Results: There were 226 patients in our study, including 85 in the baseline period. Correct diagnosis of BPD increased from 49% to 95%, the percentage of scheduled appointments increased from 71.9% to 100%, and the percentage of appointments attended increased from 55.6% to 87.1%. Conclusions: Our quality improvement initiative improved the accuracy of diagnosis, severity classification, and outpatient pulmonary follow-up of children with moderate and severe BPD.

RESUMEN

Phenol is a toxic aromatic compound used or produced in many industries and as a result a common component of industrial wastewaters. Phenol containing waste streams are frequently hypersaline and therefore require halophilic microorganisms for efficient biotreatment without dilution. In this study three halophilic bacteria isolated from different saline environments and identified as Halomonas organivorans, Arhodomonas aquaeolei and Modicisalibacter tunisiensis were shown to be able to grow on phenol in hypersaline media containing 100 g/L of total salts at a concentration of 3 mM (280 mg/L), well above the concentration found in most waste streams. Genes encoding the aromatic dioxygenase enzymes catechol 1,2 dioxygenase and protocatechuate 3,4-dioxygenase were present in all strains as determined by PCR amplification using primers specific for highly conserved regions of the genes. The gene for protocatechuate 3,4-dioxygenase was cloned from the isolated H. organivorans and the translated protein was evaluated by comparative protein sequence analysis with protocatechuate 3,4-dioxygenase proteins from other microorganisms. Although the analysis revealed a wide range of sequence divergence among the protocatechuate 3,4-dioxygenase family, all of the conserved domain amino acid structures identified for this enzyme family are identical or conservatively substituted in the H. organivorans enzyme.

RESUMEN

Gastric pneumatosis (GP) is a rare finding. It can be seen with both gastric emphysema (GE) and emphysematous gastritis (EG); however, both conditions present similarly and differentiating between the 2 is difficult radiographically. Moreover, the treatment is vastly different for both conditions, in which treatment for GE is focused on supportive care while treatment for EG may even involve gastrectomy. Making the distinction between GE and EG is crucial because GE has a benign clinical course, while EG carries significant mortality. Early endoscopy may be a useful tool in differentiating between the 2 conditions and to guide further management. Herein, we present a case series of 2 immunocompromised patients who presented with symptoms and radiographic evidence consistent with gastric pneumatosis. We found that early endoscopy assisted in risk stratification and helped guide our management strategy. We recommend consideration of endoscopic evaluation as part of ritualized evaluation of patients presenting with gastric pneumatosis.

RESUMEN

Esophageal injuries are typically iatrogenic after endoscopic/surgical procedures, but they are rarely caused by penetrative or blunt trauma. We present a case of patient who suffered multiple stab wounds to the neck and underwent surgical repair for hemorrhagic shock but was ultimately diagnosed and treated successfully via endoscopy for a thoracic esophageal injury. Early detection is imperative and usually diagnosed via contrast studies but less commonly via direct visualization endoscopically. Moreover, endoscopic treatment is also less commonly utilized, even if diagnosed from that modality. Cervical injuries also confer a lower mortality than thoracic injuries.

RESUMEN

We present the case of an 88-year-old man with a previous medical history of severe colitis and colonic strictures who presented with hematemesis. The patient was found to have a lower esophageal ulcer without any signs of perforation. Esophagogastroduodenoscopy (EGD) revealed a scar in the greater curvature of the stomach from a previously removed gastrostomy tube two months prior. On CT imaging, an incidental finding of pneumoperitoneum was also found alongside stomach perforation near the healing scar. Due to the lack of evidence of any other colonic perforation, the patient was believed to have developed this pneumoperitoneum status post-gastrectomy tube removal two months prior to presentation. Pneumoperitoneum has a wide range of presenting symptoms that vary in severity and nature, and our patient failed to present with any physical or laboratory signs of infection. Over the course of the next four months, the patient was monitored with serial CT scans, during which the pneumoperitoneum resolved. In this report, we present a case of a patient who was found to develop pneumoperitoneum post-gastric tube removal and its complete resolution without surgical or procedural intervention.

RESUMEN

OBJECTIVE: We examined weight loss patterns and feeding practices of infants hospitalized for neonatal opioid withdrawal syndrome (NOWS) managed by the eat, sleep, console approach, which emphasizes nonpharmacologic treatment. Although feeding practices during hospitalization vary widely, weight loss patterns for infants managed under this approach have not yet been described. METHODS: Of 744 infants with NOWS born from 2014 to 2019 at our institution, 330 met inclusion criteria (≥35 weeks' gestation and no NICU transfer). We examined maximum weight loss and created weight loss percentile curves by delivery type using mixed effects quantile modeling with spline effect for hour of life; 95% confidence intervals (CI) were compared to published early weight loss nomograms. RESULTS: In the cohort, the mean gestational age was 39.2 weeks, mean birth weight was 3.1 kg, and mean length of stay was 6.5 days; 94.6% did not require pharmacologic treatment. Median percent weight loss was significantly more compared to early weight loss nomograms for both vaginally-delivered infants at 48 hours (6.9% [95% CI: 5.8-8.5] vs 2.9%) and cesarean-delivered infants at 48 hours (6.5% [95% CI: 4.1-9.1] vs 3.7%) and 72 hours (7.2% [95%CI 4.7-9.9] vs 3.5%), all P < .001. Overall, 27.9% lost >10% birth weight. CONCLUSIONS: We demonstrate weight loss patterns of infants with NOWS managed by the eat, sleep, console approach at a single center. Infants with NOWS lose significantly more weight than nonopioid exposed infants and are at increased risk of morbidity and health care use. Studies to address optimal feeding methods in these infants are warranted.

RESUMEN

Intraductal papillary mucinous neoplasms (IPMN) are mucin producing tumors which arise from epithelial cells of the main pancreatic duct, pancreatic branch ducts, or both. They are characterized by mucin-producing columnar cells, papillary ductal proliferation, cyst formation, and varying degrees of dysplasia. IPMNs are classified as main duct or branch duct based upon the pancreatic duct anatomy which the IPMN is arising from. Additionally, they can be classified based on their histologic subtypes, which carry varying associations with dysplasia and/or malignancy. Many patients have incidentally identified IPMNs, which are asymptomatic. However, patients may also present with pancreatitis, elevation of liver enzymes, dilation of the pancreatic duct or bile duct as well as distention of the ampullary pancreatic orifice(s), due to impaction and obstruction with mucus. This is known as an endoscopically visualized "fish eye" sign. Patients may also develop exocrine and endocrine pancreatic insufficiency and maldigestion. Some studies also suggest that patients with IPMNs may also be at increased risk for gastric, colorectal, biliary, renal cell, and thyroid malignancies. Rarely, IPMNs can be complicated by fistulation between the main pancreatic duct and neighboring organs. Herein, we present an unusual case of simultaneous fistulation to both the gastric body and the duodenum.
