BACKGROUND: Positive toxicology testing at delivery can have enormous consequences for birthing persons and their families, including charges of child abuse or neglect and potential loss of custody for the birthing parent. Therefore state and national guidelines stipulate that, clinicians must obtain consent before toxicology testing at delivery. OBJECTIVE: This study aimed (1) to determine clinician documentation of patient consent for peripartum toxicology testing and (2) to characterize the extent to which patient and hospital characteristics were associated with documented consent...

Widely acknowledged is the disproportionate number of COVID-19 cases among nursing home residents. This observational study examined the relationship between accreditation status and COVID-19 case rates in states where the numbers and proportions of Joint Commission accredited facilities made such comparisons possible (Illinois (IL), Florida (FL), and Massachusetts (MA)). COVID-19 data were accessed from the Centers for Medicare & Medicaid Services (CMS) Nursing Home Compare Public Use File, which included retrospective COVID-19 data submitted by nursing homes to the Centers for Disease Control and Prevention (CDC) National Healthcare Safety Network...

Importance: Although critical to patient safety, health care-related allergic reactions are challenging to identify and monitor. Objective: To develop a deep learning model to identify allergic reactions in the free-text narrative of hospital safety reports and evaluate its generalizability, efficiency, productivity, and interpretability. Design, Setting, and Participants: This cross-sectional study analyzed hospital safety reports filed between May 2004 and January 2019 at Brigham and Women's Hospital and between April 2006 and June 2018 at Massachusetts General Hospital in Boston...

Primary intraosseous myoepithelial tumors are rare neoplasms with only a handful of cases described in the medical literature. To date, intraosseous variant of benign myoepithelioma, due to its rarity, has not been studied ultrastructurally, and only one case of a malignant intraosseous myoepithelioma has been described. Three cases were retrieved from the files at the Massachusetts General Hospital (MGH). A diagnosis of benign myoepithelioma was made in case 1 and malignant epithelioma in cases 2 and 3. Ultrastructurally, intermediate filaments (without dense bodies) were found in each case with an abundance in case 1 and lesser amounts in cases 2 and 3...

BACKGROUND: Pharmacies are the most accessible healthcare settings across urban, suburban, and rural areas of the United States and, thus a key venue in the overdose risk environment. Pharmacy dispensing of naloxone is part of the public health response to the opioid overdose crisis, yet little is known about the pharmacy- and community-level characteristics with which naloxone provision is associated. METHODS: We conducted a longitudinal analysis of pharmacy-level quarterly naloxone dispensed from one large US community pharmacy chain from the 1st quarter of 2013 to the 2nd quarter of 2017, examining associations between naloxone provision and pharmacy-level characteristics and community factors in two US states, Rhode Island and Massachusetts...

AIMS: To examine how the risks of incident opioid use disorder (OUD), nonfatal and fatal overdose have changed over time among opioid-naïve individuals receiving an initial opioid prescription. DESIGN: Retrospective, longitudinal study using the Massachusetts Chapter 55 dataset which linked multiple administrative datasets to study the opioid epidemic. We identified the cumulative incidence of OUD, nonfatal and fatal overdose among the opioid-naïve initiating opioid treatment in Massachusetts from 2011 to 2014 and estimated rates of these outcomes at 6 months and at 1, 2, 3 and 4 years through 2015...

PURPOSE: Although oral maxillofacial surgeons (OMSs) carry high legal risk in malpractice lawsuits, data elucidating the reason behind those claims and their outcomes are scarce. The purpose of the present study was to characterize the trends, analyze the payouts, and determine the etiology of malpractice cases against OMSs. MATERIALS AND METHODS: A retrospective case series study was performed using the Westlaw database to access medical malpractice cases filed against OMSs from 1980 to 2017...

BACKGROUND: Mutational status for KRAS, NRAS, and BRAF genes should be performed on all colorectal carcinoma (CRC) specimens in order to guide targeted therapy selection for metastatic disease. Mutations are typically assessed via polymerase chain reaction and/or next generation sequencing (NGS) on formalin-fixed paraffin-embedded tissues. With minimally invasive diagnostic methodologies, the cytology cell pellet obtained by fine-needle aspiration (FNA) can serve as an alternative source of tumor deoxyribonucleic acid...

Importance: A foundational issue in firearms policy has been whether the type of weapon used in an assault affects the likelihood of death. Objective: To determine whether the likelihood of death from gunshot wounds inflicted in criminal assaults is associated with the power of the assailant's firearm as indicated by its caliber. Design, Setting, and Participants: Cross-sectional study with multivariate analysis of data on shooting cases extracted by the authors from police investigation files for assaults that took place in Boston, Massachusetts, between January 1, 2010, and December 31, 2014...

PURPOSE: Novel cancer immunotherapies, called immune checkpoint inhibitors, have demonstrated clinical efficacy in the treatment of squamous cell carcinomas of the head and neck. Tissue expression of programmed cell death 1 ligand 1 (PD-L1) and programmed cell death 1 ligand 2 (PD-L2) has been shown to predict tumor response to these drugs. We examine the expression of prognostic immune biomarkers, PD-L1 and PD-L2, in invasive ocular surface squamous neoplasia. DESIGN: Retrospective case series...

BACKGROUND: Residual neuromuscular block (rNMB) after surgery is not difficult to identify if proper neuromuscular monitoring is used, but many clinicians do not use quantitative neuromuscular monitoring. OBJECTIVE: The aim of this study was to develop a REsidual neuromuscular block Prediction Score (REPS) to predict postoperative rNMB and compare the predictive accuracy of the prediction score with train-of-four count (TOFC) measurement at the end of a surgical case...

Mammary analogue secretory carcinoma (MASC) of the salivary glands is a recently described neoplasm of the salivary glands with a characteristic morphology complemented by a specific cytogenetic translocation and gene rearrangements. Although immunophenotypic and cytogenetic differences allow for a more reliable distinction, ultrastructural features can also provide important information about the relationship between MASC, classic acinic cell carcinoma (AciCC), and AciCC intercalated duct cell-predominant variant...

OBJECTIVES: Inhalational anesthetics are bronchodilators with immunomodulatory effects. We sought to determine the effect of inhalational anesthetic dose on risk of severe postoperative respiratory complications. DESIGN: Prospective analysis of data on file in surgical cases between January 2007 and December 2015. SETTING: Massachusetts General Hospital (tertiary referral center) and two affiliated community hospitals. PATIENTS: A total of 124,497 adult patients (105,267 in the study cohort and 19,230 in the validation cohort) undergoing noncardiac surgical procedures and requiring general anesthesia with endotracheal intubation...

Cyanide toxicity is common after significant smoke inhalation. Two cases are presented that provide framework for the discussion of epidemiology, pathogenesis, presenting signs and symptoms, and treatment options of inhalational cyanide poisoning. An evidence-based algorithm is proposed that utilizes point-of-care testing to help physicians identify patients who benefit most from antidotal therapy.
