Clinically defining the opioid-exposed birthing person and infant as a dyad to support bedside care, surveillance, and research

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.

A Dyadic Framework of Care for Opioid-exposed Birthing Persons and Their Infants and Children

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.

Improving Palivizumab Administration to High-Risk Infants with Heart Disease via a Communication-Based Quality Improvement Initiative

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.

Gastric pneumatosis in immunocompromised patients: A report of 2 cases and comprehensive literature review

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.

A Case of a gastropancreatic fistula in the setting of intraductal papillary mucinous neoplasms

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.

Standardizing the Clinical Definition of Opioid Withdrawal in the Neonate

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.

Does Maternal Incarceration Impact Infants with Neonatal Abstinence Syndrome?

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.

Improving Guidance and Maternal Knowledge Retention After Well-Newborn Unit Discharge

BACKGROUND AND OBJECTIVES

In 2015, the American Academy of Pediatrics published a policy statement to provide best practices on mother-infant discharge criteria, including the delivery of anticipatory guidance to mothers of healthy newborns. In our large health system with a mix of hospital types, no standard approach to or measurement of the effectiveness of newborn discharge guidance exists. At one community well-newborn unit, we aimed to increase maternal knowledge retention of newborn guidance from 69% to 90%.

METHODS

Data about newborn guidance effectiveness were collected by assessing maternal knowledge retention through phone follow-up quizzes. By using quality improvement methodology and informed by American Academy of Pediatrics guidelines and curricular and adult learning theory, we standardized a multidisciplinary approach to this education. Interventions included checklist, scripts, temperature-taking demonstration, gift thermometer, staff education, car seat infant mannequin, and car seat training video for staff.

RESULTS

Over a 1-year period, 333 mothers were interviewed after discharge from the well-newborn unit. Baseline data over the first 3 months (n = 93) showed poor maternal knowledge retention (69% correct answers). Common incorrect answers were on newborn urination habits, car seat harness clip positioning, and fever recognition. After restructuring the educational process, special cause was achieved after 3 months, with a shift of the average of correct answers to 83% followed by a second shift to 86%.

CONCLUSIONS

The implementation of interventions to standardize newborn discharge guidance resulted in marked and sustained improvement in maternal knowledge after well-newborn unit discharge. Our next step is to enhance the process by using videos with systemwide implementation.

The Effect of Sitting Versus Standing on Family Perceptions of Family-Centered Rounds

OBJECTIVE

Previous studies reveal improved perception of time spent, as well as overall experience, for patients when their inpatient provider is seated during an encounter. With our study, we aim to establish whether family experience and perception of time is improved when a pediatric inpatient provider team sits for patient and family-centered rounds.

PATIENTS AND METHODS

From February 2017 to November 2017, 99 inpatient encounters were randomly assigned to either a sitting or standing rounding team. Mean total time spent on rounds, family perception of time spent on rounds, and overall family experience with rounds (by using top-box analysis of physician communication questions) were compared between the 2 groups.

RESULTS

Total time spent on rounds was similar between the 2 groups (14.2 minutes in the sitting group and 12.7 minutes in the standing group; P = .23), and families in general overestimated the time spent with physicians in both groups (15.9 minutes in sitting group and 14.8 minutes in the standing group; P = .45). There were no significant differences in top-box experience responses (62% in sitting and 55% in standing; P = .12).

CONCLUSIONS

Sitting during the patient and family-centered rounds encounter did not affect actual or perceived time spent during rounds. Families may have a slightly more positive experience with seated rounds, but the difference in this study did not reach a level of statistical significance.

Downstream effects of polypathology on neurodegeneration of medial temporal lobe subregions

The medial temporal lobe (MTL) is a nidus for neurodegenerative pathologies and therefore an important region in which to study polypathology. We investigated associations between neurodegenerative pathologies and the thickness of different MTL subregions measured using high-resolution post-mortem MRI. Tau, TAR DNA-binding protein 43 (TDP-43), amyloid-β and α-synuclein pathology were rated on a scale of 0 (absent)-3 (severe) in the hippocampus and entorhinal cortex (ERC) of 58 individuals with and without neurodegenerative diseases (median age 75.0 years, 60.3% male). Thickness measurements in ERC, Brodmann Area (BA) 35 and 36, parahippocampal cortex, subiculum, cornu ammonis (CA)1 and the stratum radiatum lacunosum moleculare (SRLM) were derived from 0.2 × 0.2 × 0.2 mm3 post-mortem MRI scans of excised MTL specimens from the contralateral hemisphere using a semi-automated approach. Spearman's rank correlations were performed between neurodegenerative pathologies and thickness, correcting for age, sex and hemisphere, including all four proteinopathies in the model. We found significant associations of (1) TDP-43 with thickness in all subregions (r =  - 0.27 to r =  - 0.46), and (2) tau with BA35 (r =  - 0.31) and SRLM thickness (r =  - 0.33). In amyloid-β and TDP-43 negative cases, we found strong significant associations of tau with ERC (r =  - 0.40), BA35 (r =  - 0.55), subiculum (r =  - 0.42) and CA1 thickness (r =  - 0.47). This unique dataset shows widespread MTL atrophy in relation to TDP-43 pathology and atrophy in regions affected early in Braak stageing and tau pathology. Moreover, the strong association of tau with thickness in early Braak regions in the absence of amyloid-β suggests a role of Primary Age-Related Tauopathy in neurodegeneration.

Improving Patient Experience Scores in a Pediatric Emergency Department

INTRODUCTION

Patient experience (PE) is an important aspect of the quality of medical care and is associated with positive health outcomes. In the pediatric emergency department (PED), PE is complicated due to the balance of needs between the patient and their family while receiving care. We identified an opportunity to improve our PE, as measured by a survey administered to patients and families following their visit to the PED.

METHODS

Utilizing quality improvement methods, we assembled a multidisciplinary team, developed our aims, and evaluated the process. We utilized a key driver diagram and run charts to track our performance. The team additionally monitored several essential subcategories in our improvement process. We aimed to improve our overall PE score from 86.1 to 89.7 over 9 months to align with institutional objectives.

RESULTS

Over 6 months, we improved our overall PE score from 86.1 to 89.8. Similarly, each of our subscores of interest (physician performance, things for patients to do in the waiting room, waiting time for radiology, staff sensitivity, and communication about delays) increased. Interventions included rounding in the waiting and examination rooms, staff training, team huddles, and a cross-department committee. All measures demonstrated sustained improvement.

CONCLUSIONS

Even in this complex setting, a multidisciplinary team's careful and rigorous process evaluation and improvement work can drive measurable PE improvement. We are continuing our efforts to further improve our performance in excellent patient-centered care to this critical population.

Pathological drivers of neurodegeneration in suspected non-Alzheimer's disease pathophysiology

Background

Little is known about the heterogeneous etiology of suspected non-Alzheimer’s pathophysiology (SNAP), a group of subjects with neurodegeneration in the absence of β-amyloid. Using antemortem MRI and pathological data, we investigated the etiology of SNAP and the association of neurodegenerative pathologies with structural medial temporal lobe (MTL) measures in β-amyloid-negative subjects.

Methods

Subjects with antemortem MRI and autopsy data were selected from ADNI (n=63) and the University of Pennsylvania (n=156). Pathological diagnoses and semi-quantitative scores of MTL tau, neuritic plaques, α-synuclein, and TDP-43 pathology and MTL structural MRI measures from antemortem T1-weighted MRI scans were obtained. β-amyloid status (A+/A−) was determined by CERAD score and neurodegeneration status (N+/N−) by hippocampal volume.

Results

SNAP reflects a heterogeneous group of pathological diagnoses. In ADNI, SNAP (A−N+) had significantly more neuropathological diagnoses than A+N+. In the A− group, tau pathology was associated with hippocampal, entorhinal cortex, and Brodmann area 35 volume/thickness and TDP-43 pathology with hippocampal volume.

Conclusion

SNAP had a heterogeneous profile with more mixed pathologies than A+N+. Moreover, a role for TDP-43 and tau pathology in driving MTL neurodegeneration in the absence of β-amyloid was supported.

Parent Perspectives on the Eat, Sleep, Console Approach for the Care of Opioid-Exposed Infants

BACKGROUND

At our institution, the treatment of infants with neonatal abstinence syndrome (NAS) is guided by a function-based assessment called the Eat, Sleep, Console (ESC) approach. Infants room in with their parent(s) on the inpatient units, and most infants are treated exclusively with nonpharmacologic interventions. The experience of parents of infants with NAS treated with the ESC approach is unknown.

METHODS

We chose a deductive, hypothesis-driven approach to perform a content analysis of transcripts from in-depth, semistructured interviews of parents of infants with NAS in our institution. Responses were audiotaped, transcribed, and reviewed by at least 3 members of the research team.

RESULTS

We interviewed 18 parents of infants with NAS. Most participants were ≥30 years, were white, and had a high school or equivalent level of education. Four major themes emerged: (1) parents were supportive of fewer interventions and normalizing of newborn care in the ESC approach; (2) parents felt encouraged to lead their infant's NAS care; (3) parents perceived gaps in communication about what to expect in the hospital immediately after delivery and during their infant's hospital stay; and (4) parents experienced feelings of guilt, fear, and stress and expressed the need for increased support.

CONCLUSIONS

Parents in our study had an overall positive experience with the ESC approach. This engagement probably contributes to the success of the ESC approach in our institution. Future opportunities include better preparation of expectant mothers and continued emotional support after delivery.

Perivesicular Abscess Drainage with Lumen-Apposing Self-Expanding Metal Stents

Abdominal and pelvic abscesses can occur due to a number of reasons, the most common being surgery. They are associated with significant morbidity and mortality. The treatment approach for these types of collections is often the initiation of broad-spectrum antibiotics, accompanied by drainage. Multiple diagnostic and therapeutic modalities have been described, including; percutaneous, transvaginal, endoscopic, and surgicaldrainage. Due to the complexity of pelvic anatomy, minimally invasive approaches such as percutaneous drainage are usually difficult. Pelvic abscesses have been historically drained through surgery. Endoscopic ultrasound (EUS)-guided interventions have emerged as an alternative for the management of difficult abdominal and pelvic abscesses. Endoscopic interventions have classically included diagnostic and therapeutic aspiration, utilizing drainage catheters with or without placement of plastic stents. More recently, the use of lumen apposing self-expanding metal stents has become a treatment option for deep pelvic abscesses. Lumen opposing metal stents (LAMS) have a saddle-shaped design with two large-diameter flanges on both ends of the stent to anchor the stent edges within the respective lumens as well asa central waist that allows for communication between the two lumens. LAMS were originally designed for transmural pancreatic fluid collection drainage; however,they have been successfully implemented for numerous other off-label uses, including the drainage of pelvic and abdominal abscesses. We present the case of a 34-year-old womanwho presented with a septated abscess located between the urinary bladder and the rectum, which was successfully and definitively drained with LAMS.

Hippocampal subfield pathologic burden in Lewy body diseases vs. Alzheimer's disease

AIMS

Lewy body diseases (LBD) are characterized by alpha-synuclein (SYN) pathology, but comorbid Alzheimer's disease (AD) pathology is common and the relationship between these pathologies in microanatomic hippocampal subfields is understudied. Here we use digital histological methods to test the association between hippocampal SYN pathology and the distribution of tau and amyloid-beta (Aβ) pathology in LBD and contrast with AD subjects. We also correlate pathologic burden with antemortem episodic memory testing.

METHODS

Hippocampal sections from 49 autopsy-confirmed LBD cases, 30 with no/low AD copathology (LBD - AD) and 19 with moderate/severe AD copathology (LBD + AD), and 30 AD patients were stained for SYN, tau, and Aβ. Sections underwent digital histological analysis of subfield pathological burden which was correlated with antemortem memory testing.

RESULTS

LBD - AD and LBD + AD had similar severity and distribution of SYN pathology (P > 0.05), CA2/3 being the most affected subfield (P < 0.02). In LBD, SYN correlated with tau across subfields (R = 0.49, P < 0.001). Tau burden was higher in AD than LBD + AD (P < 0.001), CA1/subiculum and entorhinal cortex (ERC) being most affected regions (P = 0.04 to <0.01). However, tau pathology in LBD - AD was greatest in CA2/3, which was equivalent to LBD + AD. Aβ severity and distribution was similar between LBD + AD and AD. Total hippocampal tau and CA2/3 tau was inversely correlated with memory performance in LBD (R = -0.52, -0.69, P = 0.04, 0.009).

CONCLUSIONS

Our findings suggest that tau burden in hippocampal subfields may map closely with the distribution of SYN pathology in subfield CA2/3 in LBD diverging from traditional AD and contribute to episodic memory dysfunction in LBD.

The differing pathophysiologies that underlie COVID-19-associated perniosis and thrombotic retiform purpura: a case series

Background

There are two distinctive acral manifestations of COVID‐19 embodying disparate clinical phenotypes. One is perniosis occurring in mildly symptomatic patients, typically children and young adults; the second is the thrombotic retiform purpura of critically ill adults with COVID‐19.

Objectives

To compare the clinical and pathological profiles of these two different cutaneous manifestations of COVID‐19.

Methods

We compared the light microscopic, phenotypic, cytokine and SARS‐CoV‐2 protein and RNA profiles of COVID‐19‐associated perniosis with that of thrombotic retiform purpura in critical patients with COVID‐19.

Results

Biopsies of COVID‐19‐associated perniosis exhibited vasocentric and eccrinotropic T‐cell‐ and monocyte‐derived CD11c⁺, CD14⁺ and CD123⁺ dendritic cell infiltrates. Both COVID‐associated and idiopathic perniosis showed striking expression of the type I interferon‐inducible myxovirus resistance protein A (MXA), an established marker for type I interferon signalling in tissue. SARS‐CoV‐2 RNA, interleukin‐6 and caspase 3 were minimally expressed and confined to mononuclear inflammatory cells. The biopsies from livedo/retiform purpura showed pauci‐inflammatory vascular thrombosis without any MXA decoration. Blood vessels exhibited extensive complement deposition with endothelial cell localization of SARS‐CoV‐2 protein, interleukin‐6 and caspase 3; SARS‐CoV‐2 RNA was not seen.

Conclusions

COVID‐19‐associated perniosis represents a virally triggered exaggerated immune reaction with significant type I interferon signaling. This is important to SARS‐CoV‐2 eradication and has implications in regards to a more generalized highly inflammatory response. We hypothesize that in the thrombotic retiform purpura of critically ill patients with COVID‐19, the vascular thrombosis in the skin and other organ systems is associated with a minimal interferon response. This allows excessive viral replication with release of viral proteins that localize to extrapulmonary endothelium and trigger extensive complement activation.

Active lifestyles moderate clinical outcomes in autosomal dominant frontotemporal degeneration

INTRODUCTION

Leisure activities impact brain aging and may be prevention targets. We characterized how physical and cognitive activities relate to brain health for the first time in autosomal dominant frontotemporal lobar degeneration (FTLD).

METHODS

A total of 105 mutation carriers (C9orf72/MAPT/GRN) and 69 non-carriers reported current physical and cognitive activities at baseline, and completed longitudinal neurobehavioral assessments and brain magnetic resonance imaging (MRI) scans.

RESULTS

Greater physical and cognitive activities were each associated with an estimated >55% slower clinical decline per year among dominant gene carriers. There was also an interaction between leisure activities and frontotemporal atrophy on cognition in mutation carriers. High-activity carriers with frontotemporal atrophy (-1 standard deviation/year) demonstrated >two-fold better cognitive performances per year compared to their less active peers with comparable atrophy rates.

DISCUSSION

Active lifestyles were associated with less functional decline and moderated brain-to-behavior relationships longitudinally. More active carriers "outperformed" brain volume, commensurate with a cognitive reserve hypothesis. Lifestyle may confer clinical resilience, even in autosomal dominant FTLD.

A case of unusual presentation of acute esophageal necrosis with pneumonia

Acute esophageal necrosis (AEN) is a rare and often fatal pathology of unclear etiology affecting the distal two-thirds of the esophagus. Typically, elderly patients with multiple comorbidities present with signs of upper gastrointestinal (GI) hemorrhage. On endoscopy, the mucosa is black due to ischemic necrosis, resulting in the commonly used term "black esophagus." We present a rare case of a 61-year-old male presenting with shortness of breath and hematemesis diagnosed as AEN through endoscopy. This case illustrates the importance of considering AEN as part of differential diagnoses in a rising elderly population with multiple comorbidities that present with upper GI hemorrhage. Treatment should be aimed at maintaining hemodynamic stability with high-dose proton pump inhibitors.

Comparison of sporadic and familial behavioral variant frontotemporal dementia (FTD) in a North American cohort

INTRODUCTION

Behavioral variant frontotemporal dementia (bvFTD) may present sporadically or due to an autosomal dominant mutation. Characterization of both forms will improve understanding of the generalizability of assessments and treatments.

METHODS

A total of 135 sporadic (s-bvFTD; mean age 63.3 years; 34% female) and 99 familial (f-bvFTD; mean age 59.9; 48% female) bvFTD participants were identified. f-bvFTD cases included 43 with known or presumed chromosome 9 open reading frame 72 (C9orf72) gene expansions, 28 with known or presumed microtubule-associated protein tau (MAPT) mutations, 14 with known progranulin (GRN) mutations, and 14 with a strong family history of FTD but no identified mutation.

RESULTS

Participants with f-bvFTD were younger and had earlier age at onset. s-bvFTD had higher total Neuropsychiatric Inventory Questionnaire (NPI-Q) scores due to more frequent endorsement of depression and irritability.

DISCUSSION

f-bvFTD and s-bvFTD cases are clinically similar, suggesting the generalizability of novel biomarkers, therapies, and clinical tools developed in either form to the other.

Re-Educating Residents About Non-Invasive Colorectal Cancer Screening: An Approach to Improving Colon Cancer Screening Compliance

Background

Colorectal cancer is the third leading cause of cancer death; therefore early detection by screening is beneficial. Residents at a clinic in NJ, USA were not offering other forms of colon cancer screening when patients refused colonoscopy, which lead to the creation of the quality improvement project.

Methods

Residents practicing at the clinic were given an anonymous survey determining which method of colon cancer screening they used and which alternative method they offered when patients refused the original method. The residents were educated about all methods of colon cancer screening and the residents were resurveyed.

Results

A total of 64% of residents offered less invasive testing when colonoscopy was refused. Six months after education, 95% of residents offered less invasive testing when colonoscopy was refused.

Conclusions

Early detection and removal of polyps by colonoscopy reduce the risk of cancer development. Colonoscopy is the gold standard for colon cancer screening; however other less invasive modalities are approved. This quality improvement project lead to offering the fecal immunochemical test or fecal occult blood test once patients refused colonoscopy at the clinic, increasing the number of patients receiving colorectal cancer screening, and thus providing better medical care.

A resident-led project to improve documentation of overweight and obesity in a primary care clinic

Background: Although the prevalence of overweight and obesity (OW/OB) has increased in the last three decades, studies show that these conditions are sub-optimally documented by physicians. Health information technology tools have varying effects on improving documentation of OW/OB but often have to be complemented with other interventions to be effective.

Objective: Upon identifying low rates of documentation of diagnoses of overweight and obesity by resident and attending physicians, despite the use of an electronic health record (EHR) with automated BMI calculations, we performed a quality improvement (QI) project to improve documentation of these diagnoses for patients in our community hospital primary care clinic.

Methods: The EHR was reviewed to determine documentation rates by resident and attending physicians between 1 March 2018 and 31 September 2018. We collected pre-intervention data, developed interventions, and implemented tests of change using Plan-Do-Study-Act (PDSA) cycles to improve documentation of OW/OB.

Results: Documentation of overweight and obesity diagnoses increased from a baseline of 46% to 79% over a 20-week period after initiation of our project.

Conclusion: We demonstrate the successful implementation of resident-led, multi-faceted interventions in a team-based QI project to optimize documentation of OW/OB in the EHR.

Chronic Pancreatitis Leading to Pancreatogenic Diabetes Presenting in Diabetic Ketoacidosis: A Rare Entity

Diabetes mellitus type 3c (DM3c) is an uncommon cause of diabetes due to pancreatic pathology. Its prevalence reaches about 5-10% among all diabetics in the Western world, largely due to chronic pancreatitis. DM3c occurs due to the destruction of the endocrine islet cells. Glucagon and insulin levels are both decreased due to the destruction of alpha and beta cells, respectively. This makes the development of diabetic ketoacidosis (DKA) a rare process in patients with DM3c because of the destruction of glucagon, which facilitates ketone production. We report a case of DM3c presenting with DKA. The patient presented with a history of chronic pancreatitis and was on pancreatic enzyme replacement therapy. Prior records revealed that HbA1c levels were normal. Prior computed tomography evidence revealed diffuse pancreatic calcifications. The patient was admitted for DKA, presenting with hyperglycemia, blood glucose of 703 mg/dL, bicarbonate of 16 mmol/L, ketones in the urine and acetone in the blood. The patient's anion gap corrected for albumin was 27. The patient was admitted to the medical intensive care unit where he was treated with intravenous (IV) insulin and IV hydration. Once the anion gap closed, the patient was transitioned to long-acting insulin. HbA1c level on admission was elevated, autoimmune causes of diabetes were sent and were negative, ruling out late onset type 1 diabetes. This shows that although it is a rare phenomenon, diabetics with DM3c can present in DKA.

Reduction in Length of Stay and Morphine Use for NAS With the "Eat, Sleep, Console" Method

OBJECTIVES

To reduce average length of stay (ALOS) in infants with neonatal abstinence syndrome (NAS) transferred to the inpatient floor from the mother-infant unit. Secondarily, we aimed to reduce morphine exposure in these infants.

METHODS

Using quality improvement methodology, we redesigned our approach to NAS on the inpatient floor. Key interventions included transitioning from a modified Finnegan Neonatal Abstinence Scoring System to the "Eat, Sleep, Console" method for withdrawal assessment, reeducation on nonpharmacologic interventions, and adding as-needed morphine as initial pharmacotherapy. Data for infants ≥35 weeks' gestation with confirmed in utero opioid exposure and worsening symptoms of NAS requiring transfer to the inpatient floor were obtained, including ALOS, number of morphine doses, and total morphine amount administered. Infants with conditions requiring nothing by mouth for >12 hours or morphine initiation in the ICU were excluded.

RESULTS

ALOS for infants (baseline n = 40; intervention n = 36) with NAS transferred to the inpatient floor decreased from 10.3 to 4.9 days. Average morphine administered decreased from 38 to 0.3 doses per infant. No infant in the intervention period required scheduled morphine. The percent of all infants transferred to the floor for NAS requiring any morphine decreased from 92% at baseline to 19% postimplementation. There were no observed adverse events or NAS-related readmissions in the intervention period.

CONCLUSIONS

Transitioning to the Eat, Sleep, Console assessment with re-enforcement of nonpharmacologic care and use of as-needed morphine as initial pharmacotherapy resulted in a notably decreased ALOS and near elimination of postnatal opioid treatment of infants with NAS managed on our inpatient floor.

Is placebo analgesia for heat pain a sensory effect? An exploratory study on minimizing the influence of response bias

•

We explored whether placebo analgesia alters afferent nociceptive processing.

•

Healthy adult participants received a standard heat placebo induction procedure.

•

Placebo manipulation was modified to reduce experimenter demand.

•

A novel inter-arm sensory discrimination task was administered.

Only placebo responders showed changes in discriminative ability.

We explored the ongoing question of whether placebo analgesia alters afferent nociceptive processing in a novel paradigm designed to minimize the role of response bias in placebo measurement. First, healthy adult participants received a standard heat placebo induction and conditioning procedure using a topical “analgesic” cream applied to one arm. During a subsequent placebo testing procedure, participants rated stimuli on the placebo-treated arm and untreated arm, using a task that minimized subjects’ ability to guess the expected response, thus reducing experimenter demand. Retrospectively participants reported moderate analgesia effectiveness (mean = 5.3/10), but for individual temperature ratings, only 2 subjects exhibited a perceptual placebo response >5 points. Next, these subjects completed a novel, exploratory task designed to measure changes in inter-arm in discriminative accuracy that would be expected from changes in afferent nociception. Both placebo responders (but no non-responders) showed reduced discriminative ability when the hotter stimulus occurred on the placebo arm, an effect consistent with alterations in nociceptive afferent flow and unlikely to be caused by response bias.

Improving Care for Sickle Cell Pain Crisis Using a Multidisciplinary Approach

OBJECTIVES

Frequent hospitalizations for sickle cell disease (SCD) vaso-occlusive crises (VOCs) are associated with school absenteeism, emotional distress, and financial hardships. Our goal was to decrease hospital days for VOC admissions by 40% over a 5-year period.

METHODS

From October 2011 to September 2016, a multidisciplinary quality-improvement project was conducted with a plan-do-study-act methodology. Five key drivers were identified and 9 interventions implemented. Interventions included individualized home pain plans, emergency department and inpatient order sets, an inpatient daily schedule, psychoeducation, and a biofeedback program. High users (≥4 admissions per year) received an individualized SCD plan and assigned mental health provider. We expanded the high-use group to include at-risk patients (3 admissions per year). Data were analyzed for patients ages 0 to 21 years admitted for VOC. Hospital days were the primary measure; the 30-day readmission rate was the balancing measure.

RESULTS

A total of 216 SCD pediatric patients were managed in 2011 with a 14% increase over 5 years. A total of 122 patients were admitted for VOC. Hospital days decreased by 61% from 59.6 days per month in the preintervention period to 23.2 days per month in the postintervention period (P < .0001). Length of stay decreased from 4.78 (SD = 4.08) to 3.84 days (SD = 2.10; P = .02). Among high users, hospital days decreased from 35.4 to 15.5 days per month. The thirty-day readmission rate decreased from 33.9% to 19.4%. Overall savings in direct hospital costs per year were $555 120.

CONCLUSIONS

A dedicated team effort with simple interventions can have a significant impact on the well-being of a patient population and hospital costs.

Neonatal abstinence syndrome

Neonates exposed prenatally to opioids will often develop a collection of withdrawal signs known as neonatal abstinence syndrome (NAS). The incidence of NAS has substantially increased in recent years placing an increasing burden on the healthcare system. Traditional approaches to assessment and management have relied on symptom-based scoring tools and utilization of slowly decreasing doses of medication, though newer models of care focused on non-pharmacologic interventions and rooming-in have demonstrated promise in reducing length of hospital stay and medication usage. Data on long-term outcomes for both traditional and newer approaches to care of infants with NAS is limited and an important area of future research. This review will examine the history, incidence and pathophysiology of NAS. We will also review diagnostic screening approaches, scoring tools, differing management approaches and conclude with recommendations for continued work to improve the care of infants with NAS.

An Initiative to Reduce Routine Viral Diagnostic Testing in Pediatric Patients Admitted with Bronchiolitis

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.

Neonatal Abstinence Syndrome Management: A Review of Recent Evidence

BACKGROUND

The evaluation and management of infants with neonatal abstinence syndrome (NAS), the constellation of opioid withdrawal specific to newborns, have received renewed attention over the past decade during a new epidemic of opioid use, misuse, abuse, and dependence. Infants with NAS often endure long and costly hospital stays.

OBJECTIVE

We aim to review recent literature on the management and outcomes of infants with, and at risk for, opioid withdrawal.

METHODS

We reviewed articles indexed in PubMed over the past 5 years that examined interventions and/or outcomes related to the management of infants with NAS. Thirty-seven studies were included in our review comprising 8 categories: 1) identification of infants at risk for NAS, 2) prenatal factors, 3) evaluation of signs and symptoms, 4) non-pharmacologic care, including rooming-in and breastfeeding, 5) standardization of traditional protocols, 6) pharmacologic management, 7) alternative treatment approaches, and 8) long-term outcomes.

RESULTS

Non-pharmacologic interventions, standardization of traditional protocols, and alternative treatment approaches were all associated with improved outcomes. Lengths of stay were generally lowest in the studies of non-pharmacologic interventions. Patients exposed to buprenorphine in utero tended to have better short-term outcomes than those exposed to methadone. Longer-term outcomes for infants with NAS appear to be worse than those of control groups.

CONCLUSION

The current epidemic necessitates both continued research, and the application of new evidence-based practices in the assessment and treatment of newborns exposed to opioids in utero. Projects focused on non-pharmacologic interventions appear to hold the most promise.

Comparison of In Vivo and Ex Vivo MRI of the Human Hippocampal Formation in the Same Subjects

Multiple techniques for quantification of hippocampal subfields from in vivo MRI have been proposed. Linking in vivo MRI to the underlying histology can help validate and improve these techniques. High-resolution ex vivo MRI can provide an intermediate modality to map information between these very different imaging modalities. This article evaluates the ability to match information between in vivo and ex vivo MRI in the same subjects. We perform rigid and deformable registration on 10 pairs of in vivo (3 T, 0.4 × 0.4 × 2.6 mm3) and ex vivo (9.4 T, 0.2 × 0.2 × 0.2 mm3) scans, and describe differences in MRI appearance between these modalities qualitatively and quantitatively. The feasibility of using this dataset to validate in vivo segmentation is evaluated by applying an automatic hippocampal subfield segmentation technique (ASHS) to in vivo scans and comparing SRLM (stratum/radiatum/lacunosum/moleculare) surface to manual tracing on corresponding ex vivo scans (and in 2 cases, histology). Regional increases in thickness are detected in ex vivo scans adjacent to the ventricles and were not related to scanner, resolution differences, or susceptibility artefacts. Satisfactory in vivo/ex vivo registration and subvoxel accuracy of ASHS segmentation of hippocampal SRLM demonstrate the feasibility of using this dataset for validation, and potentially, improvement of in vivo segmentation methods.

Novel conformation-selective alpha-synuclein antibodies raised against different in vitro fibril forms show distinct patterns of Lewy pathology in Parkinson's disease

AIMS

The aim of this study was to test the hypothesis that different conformations of misfolded α-synuclein (α-syn) are present in Parkinson's disease (PD) brain.

METHODS

Using two previously characterized conformations of α-syn fibrils, we generated new conformation-selective α-syn monoclonal antibodies (mAbs). We then interrogated multiple brain regions in a well-characterized autopsy cohort of PD patients (n = 49) with these mAbs, Syn7015 and Syn9029.

RESULTS

Syn7015 detects Lewy bodies (LBs) and Lewy neurites (LNs) formed by pathological α-syn in all brain regions tested, and is particularly sensitive to LNs and small Lewy dots, inclusions believed to form early in the disease. Further, we observed colocalization between Syn7015 and an early marker of α-syn pathology formation, phospho-Ser129-α-syn, and a lack of extensive colocalization with markers of more mature pathology. In comparison, Syn9029 detects Lewy pathology in all regions examined, but indicates significantly fewer LNs than Syn7015. In addition, colocalization of Syn9029 with later markers of α-syn pathology maturation (ubiquitin and P62) suggests that the pathology detected by Syn9029 is older. Semiquantitative scoring of both LN and LB pathology in nine brain regions further established this trend, with Syn7015 LN scores consistently higher than Syn9029 LN scores.

CONCLUSIONS

Our data indicate that different conformations of α-syn pathology are present in PD brain and correspond to different stages of maturity for Lewy pathology. Regional analysis of Syn7015 and Syn9029 immunostaining also provides support for the Braak hypothesis that α-syn pathology advances through the brain.

Progression of alpha-synuclein pathology in multiple system atrophy of the cerebellar type

AIMS

The aim of this study was to identify early foci of α-synuclein (α-syn pathology) accumulation, subsequent progression and neurodegeneration in multiple system atrophy of the cerebellar type (MSA-C).

METHODS

We analysed 70-μm-thick sections of 10 cases with MSA-C and 24 normal controls.

RESULTS

MSA-C cases with the lowest burden of pathology showed α-syn glial cytoplasmic inclusions (GCIs) in the cerebellum as well as in medullary and pontine cerebellar projections. Cerebellar pathology was highly selective and severely involved subcortical white matter, whereas deep white matter and granular layer were only mildly affected and the molecular layer was spared. Loss of Purkinje cells increased with disease duration and was associated with neuronal and axonal abnormalities. Neocortex, basal ganglia and spinal cord became consecutively involved with the increasing burden of α-syn pathology, followed by hippocampus, amygdala, and, finally, the visual cortex. GCIs were associated with myelinated axons, and the severity of GCIs correlated with demyelination.

CONCLUSIONS

Our findings indicate that cerebellar subcortical white matter and cerebellar brainstem projections are likely the earliest foci of α-syn pathology in MSA-C, followed by involvement of more widespread regions of the central nervous system and neurodegeneration with disease progression.

Pancreatic Lesion: Malignancy or Abscess?

BACKGROUND

Pancreatic abscesses are rare. They may be seen in patients with pancreatic inflammation or pancreatitis. Patients with pancreatic abscesses may have abdominal pain, fever, chills, and nausea/vomiting or an inability to eat. Presentation with alternate symptomatology is extremely unusual.

CASE REPORT

A 67-year-old Asian male presented with painless, afebrile obstructive jaundice and a CA 19-9 of 1732 IU. He was found to have a 3.1×2.4 cm low-density lesion in the head of the pancreas and the right lobe of the liver, suggesting malignancy. Surgical management was considered, however additional diagnostic workup, including an endoscopic retrograde cholangiopancreatography (ERCP), was performed to complete staging of the presumed mass. A smooth, 3-cm-long, tapering stricture was found it the common bile duct. It was stented from the common hepatic duct to the duodenum. Subsequent endoscopic ultrasound (EUS) evaluation of the pancreatic head lesion revealed a drainable fluid collection that was aspirated and found to contain pyogenic material on pathology. The patient's symptoms resolved, and he was subsequently managed conservatively. A repeat ERCP confirmed complete resolution of the previously visualized cystic lesion. Interestingly, laboratory values showed concomitant normalization of CA 19-9 to 40 IU.

CONCLUSIONS

EUS-guided biopsy is not widely regarded as a required step before surgery, in the management of patients with pancreatic masses. It is generally reserved for determination of resectability or staging, and only utilized when clinically indicated. However, this practice may be associated with an inherently significant risk of misdiagnosis and subsequent unnecessary surgery, as illustrated by this case. Malignancy was initially suspected in our patient and surgical resection was recommended. Endoscopic measures were only pursued to complete staging. We propose that EUS-guided biopsy may be a crucial diagnostic step in the management algorithm of pancreatic lesions in selected patients. In addition, we encourage consideration of nonmalignant pancreatic collections in the differential diagnosis of pancreatic masses, especially when present in patients with diabetes mellitus.

A Qualitative Analysis of Pediatric Patient Attitudes Regarding Family-Centered Rounds

BACKGROUND AND OBJECTIVES

The American Academy of Pediatrics recommends family-centered rounds (FCR) as standard practice for the inpatient setting. To date, there is limited research investigating the attitudes of pediatric patients regarding this shift in practice. The goal of this study was to explore pediatric patients' perspectives of their experiences during FCR.

METHODS

We conducted a qualitative descriptive study based on results from 22 semi-structured interviews of school-aged and adolescent inpatients from September 2012 through October 2013. English-speaking patients, aged 7 to 18 years, who participated in FCR were eligible for inclusion. Transcripts were initially analyzed by using a constant comparative method. After completion of this initial analysis, a third reviewer independently reviewed all transcripts to verify the accuracy of the final coding scheme.

RESULTS

The final coding scheme consisted of 5 main themes: team size, medical team interactions, content discussed on FCR, setting expectations, and timing and location of FCR. In general, patients expressed a wide array of positive, negative, and neutral impressions within each theme relating to their experiences with FCR.

CONCLUSIONS

Patient comments regarding their experience with FCR offer unique perspectives from previously studied participants, including physicians, nurses, students, and parents. Future research aimed at evaluating the bedside rounding process should incorporate patients' views to realize the complete FCR experience.

The utility of inpatient rebound bilirubin levels in infants readmitted after birth hospitalization for hyperbilirubinemia

BACKGROUND AND OBJECTIVES

There are few data evaluating the role of inpatient rebound bilirubin levels in the management of infants readmitted after their birth hospitalization for indirect hyperbilirubinemia. The goal of the present study was to evaluate the clinical utility of inpatient rebound bilirubin levels within this patient population.

METHODS

A retrospective cohort study was conducted of 226 infants readmitted after their birth hospitalization for indirect hyperbilirubinemia. Data from 130 infants with rebound bilirubin levels drawn at a mean of 6.1±2.4 hours after discontinuation of phototherapy were compared with data from 96 infants without rebound bilirubin levels. The primary outcome was readmission to the hospital, and secondary outcomes included length of stay and discharge time. A subgroup analysis compared characteristics of children who required repeat phototherapy versus those who did not.

RESULTS

Overall, 5 of 130 patients from the rebound group were readmitted compared with 4 of 96 patients from the no-rebound group (P=.98). Length of stay was significantly longer for patients with rebound bilirubin levels (27.7 vs 23.2 hours; P=.001). Patients with bilirubin levels lowered to ≤14 mg/dL were less likely to receive repeat phototherapy than those with levels>14 mg/dL (2 of 129 vs 12 of 97; P=.001).

CONCLUSIONS

Early inpatient rebound bilirubin levels do not successfully predict which patients will require hospital readmission for repeat phototherapy. Children with bilirubin levels lowered to ≤14 mg/dL with phototherapy are unlikely to receive repeat phototherapy.

Staphylococcus aureus sporotrichoid lymphangitis without bacteremia in a transplant recipient

Pyogenic sporotrichoid infections are rare. There are only 4 reports in the literature of Staphylococcus aureus presenting as sporotrichoid lymphangitis (also known as lymphocutaneous syndrome or nodular lymphangitis). We report the first case, to our knowledge, of S. aureus sporotrichoid infection without bacteremia in an immunocompromised organ transplant recipient.

Progressive Nonfluent Aphasia: Language, Cognitive, and PET Measures Contrasted with Probable Alzheimer's Disease

The purpose of this study was to compare the language and cognitive profiles of four progressive nonfluent aphasia (PNFA) patients with 25 probable Alzheimer's disease (pAD) patients, and to identify the distinct cortical defects associated with cognitive deficits in PNFA using positron emission tomography (PET). Longitudinal observations of PNFA patients revealed progressively telegraphic speech and writing and a gradual deterioration of sentence comprehension, but memory and visual functioning were relatively preserved. Direct contrast with PAD patients revealed that PNFA patients are significantly impaired on grammatical phrase structure aspects of sentence comprehension and expression, phonemic judgments, repetition, and digit span, but not on other cognitive measures. PET studies of PNFA revealed reduced cortical activity throughout the left hemisphere. In addition, there was a prominent defect in left superior and middle temporal and inferior frontal regions of PNFA patients that differed significantly from the distribution of regional cerebral dysfunction in pAD. We conclude that PNFA is associated with a distinct profile of language and cognitive difficulty, and that this pattern of impairment is related to cortical dysfunction in a specific distribution of the left hemisphere.

The potential role for acupuncture in treating symptoms in patients with lung cancer: an observational longitudinal study

BACKGROUND

Most lung cancer patients experience multiple symptoms related either to the disease or its treatment. The commonly reported symptoms are pain, depression, anxiety, nausea, and poor well-being. The aim of the present study was to evaluate the effect of acupuncture as a potential treatment modality in symptomatic lung cancer patients.

METHODS

This prospective observational study enrolled 33 lung cancer patients from the Peter Brojde Lung Cancer Centre between August 2010 and May 2012. All patients received 45-minute sessions of acupuncture, 1-2 times weekly for a minimum of 4 sessions. Symptom severity was assessed using the Edmonton Symptom Assessment System (esas) before and after completion of acupuncture.

RESULTS

The study cohort included 30 patients with non-small- cell lung cancer and 3 with small-cell lung cancer. Mean age was 62 years (range: 36-88 years); 17 of the patients were women. Most of the patients had advanced-stage cancer (73%) and good performance status (Eastern Cooperative Oncology Group 0-1: 88%). Of these patients, 67% received anticancer treatment (chemotherapy or radiotherapy, or both) with acupuncture. Of the remaining 10 patients, 8 received acupuncture after a complete surgical resection of their tumour, and because of their advanced age, 2 received acupuncture and best supportive care. The median number of acupuncture sessions was 7 (interquartile range: 4-13 sessions). Statistically significant improvements in pain, appetite, nausea, nervousness, and well-being were observed. A clinically important improvement (2 points on the esas) was reported by 61% of patients for pain and by 33% for well-being. A significant positive correlation between improved well-being and the number of acupuncture sessions was observed. This correlation remained significant even after controlling for treatment and narcotic use. Receiver operating characteristic analysis demonstrated that a minimum of 6 acupuncture sessions are required for a 70% chance of a clinically important improvement in well-being.

CONCLUSIONS

The present study is the first to demonstrate that acupuncture may be an effective approach for improving symptoms-in particular, pain and well-being-in lung cancer patients. Acupuncture is a safe and minimally invasive procedure, and it is potentially useful even in patients undergoing anticancer treatment.
