Urgent Follow-up after Outpatient Nonstress Tests and the Potential for Fetal Monitoring at Home.

OBJECTIVE: This study aimed to measure the proportion of patients needing urgent clinical follow-up after an abnormal outpatient nonstress test (NST). We further sought to capture the patient perspective on the acceptability of performing NSTs at home. STUDY DESIGN: A retrospective cohort study was performed over a 2-year period to determine the frequency of abnormal NSTs in a hospital-based, antepartum testing unit in patients greater than or equal to 32 weeks' gestation. The proportion of patients who delivered within 24 hours of an abnormal NST was also determined. A cross-sectional, web-based patient survey was conducted to obtain insight into the patient's comfort level with potentially performing NSTs at home. RESULTS: The chart review yielded 665 patients who underwent 2,122 NSTs at greater than or equal to 32 weeks. Of the 2,122 NSTs, 111 were categorized as abnormal and required urgent clinical follow-up, or 5.2% (95% confidence interval [CI] 4.3, 6.3%). Of the 665 patients, 13 delivered within 24 hours of an abnormal NST, or 2.0% (95% CI 1.0, 3.3%). In the web-based survey, the proportion of respondents who would feel comfortable or very comfortable conducting NSTs at home was 87/125, or 69.6% (95% CI 60.9, 77.1%). CONCLUSION: This study revealed that 5.2% of NSTs performed in a hospital-based antepartum testing unit were abnormal and required urgent clinical follow-up. Of the patients being followed in the antepartum testing unit, 2.0% delivered within 24 hours of an abnormal NST. The majority of the survey respondents indicated they would feel comfortable performing NSTs at home. The present study adds important information regarding the risks and benefits of NSTs at home. KEY POINTS: · Telehealth for NSTs offers advantages over in-person NSTs.. · The proportion of NSTs that need urgent follow-up was 5.2%.. · A majority of patients are interested in telehealth for NSTs.. · Guidelines are needed before adoption of telehealth for NSTs..

Association of High Tumor Mutation Burden in Non-Small Cell Lung Cancers With Increased Immune Infiltration and Improved Clinical Outcomes of PD-L1 Blockade Across PD-L1 Expression Levels.

Importance: Although tumor mutation burden (TMB) has been explored as a potential biomarker of immunotherapy efficacy in solid tumors, there still is a lack of consensus about the optimal TMB threshold that best discriminates improved outcomes of immune checkpoint inhibitor therapy among patients with non-small cell lung cancer (NSCLC). Objectives: To determine the association between increasing TMB levels and immunotherapy efficacy across clinically relevant programmed death ligand-1 (PD-L1) levels in patients with NSCLC. Design, Setting, and Participants: This multicenter cohort study included patients with advanced NSCLC treated with immunotherapy who received programmed cell death-1 (PD-1) or PD-L1 inhibition in the Dana-Farber Cancer Institute (DFCI), Memorial Sloan Kettering Cancer Center (MSKCC), and in the Stand Up To Cancer (SU2C)/Mark Foundation data sets. Clinicopathological and genomic data were collected from patients between September 2013 and September 2020. Data analysis was performed from November 2021 to February 2022. Exposures: Treatment with PD-1/PD-L1 inhibition without chemotherapy. Main Outcomes and Measures: Association of TMB levels with objective response rate (ORR), progression-free survival (PFS), and overall survival (OS). Results: In the entire cohort of 1552 patients with advanced NSCLC who received PD-1/PD-L1 blockade, the median (range) age was 66 (22-92) years, 830 (53.5%) were women, and 1347 (86.8%) had cancer with nonsquamous histologic profile. A regression tree modeling ORR as a function of TMB identified 2 TMB groupings in the discovery cohort (MSKCC), defined as low TMB (≤19.0 mutations per megabase) and high TMB (>19.0 mutations per megabase), which were associated with increasing improvements in ORR, PFS, and OS in the discovery cohort and in 2 independent cohorts (DFCI and SU2C/Mark Foundation). These TMB levels also were associated with significant improvements in outcomes of immunotherapy in each PD-L1 tumor proportion score subgroup of less than 1%, 1% to 49%, and 50% or higher. The ORR to PD-1/PD-L1 inhibition was as high as 57% in patients with high TMB and PD-L1 expression 50% or higher and as low as 8.7% in patients with low TMB and PD-L1 expression less than 1%. Multiplexed immunofluorescence and transcriptomic profiling revealed that high TMB levels were associated with increased CD8-positive, PD-L1-positive T-cell infiltration, increased PD-L1 expression on tumor and immune cells, and upregulation of innate and adaptive immune response signatures. Conclusions and Relevance: These findings suggest that increasing TMB levels are associated with immune cell infiltration and an inflammatory T-cell-mediated response, resulting in increased sensitivity to PD-1/PD-L1 blockade in NSCLC across PD-L1 expression subgroups.

Case Series: Redefining Severe Grade 5 Vaginismus.

INTRODUCTION: Vaginismus is poorly understood and relatively unknown among health care providers. For those who understand and treat vaginismus, few make an assessment of the severity of this condition. The importance of classifying the severity of vaginismus impacts the clinician's ability to diagnose and treat vaginismus, and understanding of the patient's experience. AIM: The aims of this paper are to identify the distinguishing features of severe grade 5 vaginismus, determine if vaginal spasm is present in severe grade vaginismus, and to establish qualifications for the Pacik grade 5 classification. METHODS: Assessment of 553 referred or self-referred women who were unable to tolerate intercourse completed a comprehensive pretreatment questionnaire. Of those women, 391 underwent a vaginal examination in a certified surgicenter using sedation and anesthesia as needed. MAIN OUTCOME MEASURE: The main outcome measures were to detect the presence of a visceral reaction with an intended or actual gynecologic examination in Grade 5 patients, and to identify vaginal spasm on examination. RESULTS: A visceral response reaction to routine gynecologic examinations, as well as spasm of the bulbocavernosum, occurred in patients with severe vaginismus. CONCLUSION: Severe vaginismus with visceral response manifestations to routine gynecologic examinations, inability to have intercourse, and spasm of the bulbocavernosum is newly defined as severe grade 5 vaginismus.

Unresponsive Intractable Chronic Headache With Sitagliptin.

Sitagliptin is an anti-diabetic medication within the dipeptidyl peptidase 4 (DPP4) inhibitor class used as a single agent or in combination therapy. It is a well-studied and well-tolerated medication with commonly reported adverse events of upper respiratory tract infections, nasopharyngitis, headache, and gastrointestinal (GI) upset. Post-marketing reports have also identified associations with acute pancreatitis and joint pain. Here, we report a case of type II diabetes with chronic headache which resolved rapidly after discontinuation of sitagliptin. Our case demonstrates the need for continuous monitoring and post-marketing surveillance for drugs with tolerable side effect profile. Also, increasing patient and physician awareness of long-term side effects of these commonly used medications is essential for adequate patient safety and quality care.

Kikuchi-Fujimoto Disease in a Young African American Male.

Kikuchi-Fujimoto disease (KFD), also known as histiocytic necrotizing lymphadenitis, is an extremely rare, self-limiting disorder which typically presents with fever and painful, unilateral cervical lymphadenopathy in previously healthy individuals. Here, we describe a case of KFD which initially presented with fever of unknown origin. Due to its non-specific symptoms and low incidence, KFD poses a diagnostic conundrum for clinicians. Awareness of this disease entity is the key for prompt diagnosis and treatment.
