FDA-Approved Janus Kinase-Signal Transducer and Activator of Transcription (JAK-STAT) Inhibitors for Managing Rheumatoid Arthritis: A Narrative Review of the Literature.

Rheumatoid arthritis (RA) is a complex autoimmune disease causing chronic joint inflammation and, in more serious cases, organ involvement. RA typically affects people between the ages of 35 and 60; however, it can also afflict children younger than the age of 16 years and can also demonstrate a pattern of remission later in the disease course. Non-steroidal anti-inflammatory drugs, glucocorticoids, exercise, and patient education are all used in the management of RA, which is divided into symptomatic management and disease-modifying management (disease-modifying antirheumatic drugs) to reduce pain and inflammation, thereby preserving joint function. Janus kinase inhibitors (JAKis) have led to a substantial improvement in the management of RA. By specifically targeting the JAK-signal transducer and activator of transcription pathway, which is essential for immunological modulation, these inhibitors also demonstrate promise in treating various autoimmune illnesses, including inflammatory bowel diseases, giant cell arteritis, ankylosing spondylitis, and psoriatic arthritis. Tofacitinib, baricitinib, upadacitinib, peficitinib, delgocitinib, and filgotinib are examples of FDA-approved JAKis that have distinct properties and indications for treating a range of autoimmune illnesses. JAKis demonstrate a promising treatment approach for managing RA and other autoimmune diseases while enhancing patient outcomes and quality of life. However, due to major safety concerns and the need for long-term success, meticulous patient monitoring is essential.

Disparities in Antifibrotic Medication Utilization Among Veterans With Idiopathic Pulmonary Fibrosis.

BACKGROUND: Two antifibrotic medications, pirfenidone and nintedanib, are approved for the treatment of idiopathic pulmonary fibrosis (IPF). Little is known about their real-world adoption. RESEARCH QUESTION: What are the real-world antifibrotic utilization rates and factors associated with uptake among a national cohort of veterans with IPF? STUDY DESIGN AND METHODS: This study identified veterans with IPF who received care either provided by the Veterans Affairs (VA) Healthcare System or non-VA care paid for by the VA. Patients who had filled at least one antifibrotic prescription through the VA pharmacy or Medicare Part D between October 15, 2014, and December 31, 2019, were identified. Hierarchical logistic regression models were used to examine factors associated with antifibrotic uptake, accounting for comorbidities, facility clustering, and follow-up time. Fine-Gray models were used to evaluate antifibrotic use by demographic factors, accounting for the competing risk of death. RESULTS: Among 14,792 veterans with IPF, 17% received antifibrotics. There were significant disparities in adoption, with lower uptake associated with female sex (adjusted OR, 0.41; 95% CI, 0.27-0.63; P < .001), Black race (adjusted OR, 0.60; 95% CI, 0.49-0.73; P < .001), and rural residence (adjusted OR, 0.88; 95% CI, 0.80-0.97; P = .012). Veterans who received their index diagnosis of IPF outside the VA were less likely to receive antifibrotic therapy (adjusted OR, 0.15; 95% CI, 0.10-0.22; P < .001). INTERPRETATION: This study is the first to evaluate the real-world adoption of antifibrotic medications among veterans with IPF. Overall uptake was low, and there were significant disparities in use. Interventions to address these issues deserve further investigation.

Implementation of a Virtual Huddle to Support Patient Care During the COVID-19 Pandemic.

Background: During a surge of COVID-19 cases, the volume of acute care patients with hypoxemic respiratory failure placed a high burden of responsibility on internal medicine, pulmonary and critical care medicine, and clinical pharmacy services. Observations: We describe the COVID-19 Tele-Huddle Program, a novel approach to communication between key stakeholders in COVID-19 patient care through a daily video conferencing huddle. The program was implemented during a 4-week surge in COVID-19 cases at a large, academic medical center in Houston, Texas. Data collected during the COVID-19 Tele-Huddle Program included the type and number of interventions implemented, number of patients discussed, and COVID-19 therapies provided. In addition, hospital medicine team members completed a user-experience survey. Conclusions: A multidisciplinary consultation service using video conferencing can support the care of patients with high disease severity without overwhelming existing inpatient medical, intensive care, and pharmacy services.

Obstructive sleep apnea in diabetic patients is associated with higher healthcare utilization.

BACKGROUND: Obstructive sleep apnea (OSA) is a frequent comorbid condition in patients with type 2 diabetic (T2DM). Concomitant OSA is associated with a detrimental impact on metabolic control. Both OSA and T2DM independently lead to increased cardiovascular disease and mortality. The impact of OSA on the acceleration of organ dysfunction leading to increased healthcare utilization is unknown. METHODS: This is a retrospective case-control cohort study, a secondary analysis utilizing a nationwide dataset. Patients who underwent elective surgical procedures from 2009 to 2014 were identified. Among these patients, we compared patients with obstructive sleep apnea and those without obstructive sleep apnea. Exact 1:1 matching was performed based on similar characteristics such as age, sex, geographic location, surgical facility environment, performing surgeon, and severity of illness during hospitalization. The subgroup of patients with T2DM with or without OSA was analyzed for post-discharge hospital admissions, intensive care unit (ICU) admissions, emergency room (ER) visits, and outpatient visits. RESULTS: Among 47,719 matched patients of the initial study, this subgroup included 4,567 patients with diabetes and OSA and 3,842 patients with diabetes but no OSA. In the presence of comorbid OSA, patients with T2DM had higher odds of increased healthcare utilization among all the outcomes: inpatient visits increased with an odds ratio of 2.50 (confidence interval (CI) 2.28-2.74) and ICU admissions 1.96 (CI 1.73-2.25) ER 1.93 **(CI 1.75-2.12) and outpatient visits 2.18 (CI 2.00-2.38). Future healthcare utilization per 100 patient-years was also increased significantly among all outcomes (p < 0.0001). CONCLUSIONS: In patients with diabetes undergoing elective surgery, the presence of OSA was associated with higher future healthcare utilization.

Harnessing Digital Health to Objectively Assess Functional Performance in Veterans with Chronic Obstructive Pulmonary Disease.

INTRODUCTION: An early detection of impaired functional performance is critical to enhance symptom management for patients with chronic obstructive pulmonary disease (COPD). However, conventional functional measures based on walking assessments are often impractical for small clinics where the available space to administrate gait-based test is limited. This study examined the feasibility and effectiveness of an upper-extremity frailty meter (FM) in identifying digital measures of functional performance and assessing frailty in COPD patients. METHODS: Forty-eight patients with COPD (age = 68.8 ± 8.5 years, body mass index [BMI] = 28.7 ± 5.8 kg/m2) and 49 controls (age = 70.0 ± 3.0 years, BMI = 28.7 ± 6.1 kg/m2) were recruited. All participants performed a 20-s repetitive elbow flexion-extension test using a wrist-worn FM sensor. Functional performance was quantified by FM metrics, including speed (slowness), range of motion (rigidity), power (weakness), flexion and extension time (slowness), as well as speed and power reduction (exhaustion). Conventional functional measures, including timed-up-and-go test, gait and balance tests, and 5 repetition sit-to-stand test, were also performed. RESULTS: Compared to controls, COPD patients exhibited deteriorated performances in all conventional functional assessments (d = 0.64-1.26, p < 0.010) and all FM metrics (d = 0.45-1.54, p < 0.050). FM metrics had significant agreements with conventional assessment tools (|r| = 0.35-0.55, p ≤ 0.001). FM metrics efficiently identified COPD patients with pre-frailty and frailty (d = 0.82-2.12, p < 0.050). CONCLUSION: This study proposes the feasibility of using a 20-s repetitive elbow flexion-extension test and wrist-worn sensor-derived frailty metrics as an alternative and practical solution to evaluate functional performance in COPD patients. Its simplicity and low risk for test administration may also facilitate its application for remote patient monitoring. Furthermore, in settings where the administration of walking test is impractical, for example, when ventilator support is needed or space is limited, FM may be used as an alternative solution. Future studies are encouraged to use the FM to quantitatively monitor the progressive decline in functional performance and quantify outcomes of rehabilitation interventions.

Differences in COVID-19-Related Testing and Healthcare Utilization by Race and Ethnicity in the Veterans Health Administration.

IMPORTANCE: Recent reports indicate differences in COVID-19-related care and outcomes between Black and White Americans. OBJECTIVE: We examine the COVID-19-related healthcare utilization and mortality by race and ethnicity of patients tested for SARS-CoV-2 in the Veterans Health Administration (VHA). DESIGN: A retrospective cohort study. SETTING: We used the VHA COVID-19 shared data resources between February 1 and June 30, 2020. PARTICIPANTS: Veterans tested for SARS-CoV-2 virus by VHA. EXPOSURE(S): Three racial-ethnicity groups of Black, Hispanic, and White (as reference) veterans. MAIN OUTCOME(S) AND MEASURE(S): Main outcomes are testing rate, positivity rate, hospitalization rate, ICU admission rate, and in-hospital mortality. Controlling for sex, age, and Elixhauser comorbidity index, we report adjusted odds ratios (aOR) and 95% confidence intervals (95% CI) from logistic regression models. RESULTS: Of the 8,667,996 active veteran enrollees, 252,702 were tested by VHA from February to June, 2020, with 20,500 positive results and 4,790 hospitalizations. The testing rate was 4.4% among Black and 4.7% among Hispanic veterans compared to White veterans, 2.8%. The testing positivity rate was similarly elevated among Black (12.2%) and Hispanic (11.6%) veterans compared to White veterans (6.0%). The aORs of hospitalization in Black veterans (1.88; 95% CI 1.74, 2.03) and Hispanic veterans (1.41; 95% CI 1.25, 1.60) were higher compared to White veterans. No significant differences by race and ethnicity were observed in OR or aOR of ICU admission and in-hospital death among hospitalized patients. CONCLUSIONS AND RELEVANCE: On a national level, the VHA was more likely to test and hospitalize Black and Hispanic veterans compared to White veterans, but there were no significant differences in ICU admission or in-hospital mortality among those hospitalized. This pattern of differences may relate to social determinants of health, factors affecting access to non-VHA care, or preferences for VHA care affecting initial care seeking, but not in-hospital outcomes.

Presence of obstructive sleep apnea is associated with higher future readmissions and outpatient visits-a nationwide administrative dataset study.

BACKGROUND: Hospital readmissions and outpatient visits contribute to the significant burden on healthcare systems. Obstructive sleep apnea (OSA) is a chronic medical condition that is associated with cardiovascular comorbidities and other chronic conditions. Inpatient and outpatient healthcare utilization rates in patients with OSA following hospitalization are unclear. METHODS: This. retrospective case-control cohort study utilized a nationwide database to assess if OSA is associated with higher healthcare utilization post-hospitalization. We compared healthcare utilization among patients with OSA versus without OSA between 2009 and 2014 after matching for demographic variables, geographic location, hospital environment, reason for admission, and severity of illness during hospitalization. We measured future healthcare utilization by the number of ICU admissions, hospital admissions, emergency room visits, and outpatient visits after being discharged from the index hospitalization. RESULTS: Two equal-sized cohorts comprised of 85,912 matched pairs were obtained. The OSA cohort demonstrated significantly higher rates of future ICU admissions, hospital admissions, emergency room visits, and outpatient visits. Matching for comorbid cardiovascular conditions continued to demonstrate higher healthcare utilization in the OSA group. Short-term outcomes during the index hospitalization were relatively similar between groups. CONCLUSIONS: This retrospective database study demonstrated that OSA may be an independent marker of higher future healthcare utilization. On the other hand, the length of stay during the index hospitalization was not elevated. Prospective studies are needed to confirm these findings and investigate the impact of directing additional resources to inpatients with OSA.

Healthcare utilization after elective surgery in patients with obstructive sleep apnea - analysis of a nationwide data set.

BACKGROUND: Obstructive sleep apnea is prevalent among those undergoing elective surgery and likely introduces a risk of adverse outcomes. To understand its impact, we aimed to compare healthcare utilization in postsurgical patients with obstructive sleep apnea compared to controls matched on the surgical care environment. METHODS: This is a retrospective case-control cohort study using a nationwide database. Among patients undergoing elective surgical procedures during 2009-2014, we compared patients with obstructive sleep apnea with those without obstructive sleep apnea. The two cohorts were matched based on age, sex, type of surgery, performing surgeon, the hospital where the procedure was performed, and various All-Patient-Refined Diagnosis-Related-Groups severity indices. The primary effect of interest was short-term healthcare utilization. We also compared long-term hospital admissions, intensive care unit admissions, emergency room visits and outpatient visits. RESULTS: 47,719 subjects and controls were matched on a 1:1 basis. As the subjects were matched, the two groups did not differ on age, percent female, and various Diagnosis-Related-Groups severity indices. The obstructive sleep apnea group had more comorbid conditions and a higher Elixhauser index. Short-term healthcare utilization measured by the length of stay and mortality related to index procedure did not increase in the sleep apnea group. In hierarchical logistical regression analysis, the presence of sleep apnea predicted higher long-term health care utilization. CONCLUSIONS: Our data suggests that the presence of sleep apnea was not associated with increased post elective surgical length of stay and mortality; however, the presence of obstructive sleep apnea was associated with long-term health care utilization.

Telehealth Pulmonary Rehabilitation for Patients With Severe Chronic Obstructive Pulmonary Disease.

For patients with chronic obstructive pulmonary disease, a home-based, interactive telehealth program can improve accessibility to pulmonary rehabilitation and reduce travel costs.

Update on management of stable chronic obstructive pulmonary disease.

Chronic obstructive pulmonary disease (COPD) is a major chronic debilitating condition with significant impact on quality of life, symptoms, comorbidity, health care utilization and longevity. The main pathophysiological hallmark of COPD is expiratory flow limitation which impairs the ability of respiratory system to adequately and properly ventilate. To be able to prognosticate and manage patients with COPD, various societies have developed classifications of disease severity. Current classification schemes combine three elements that include lung function, patient reported symptoms (shortness of breath) and frequency of exacerbations. Global Initiative for Obstructive Lung Disease (GOLD), an international guideline for diagnosis and management of COPD, started using this approach since the 2011 revision. Management according to this scheme has been developed and is in use. Comprehensive COPD management is multifaceted. It includes pharmacologic management, patient education, smoking cessation, influenza and pneumococcal vaccinations, depression and anxiety management, pulmonary rehabilitation, and if indicated, home oxygen therapy. The following chapter will review management recommendations currently in use for stable COPD. We intend to make the chapter to the point and practical and avoid an exhaustive review of the literature.

A multicenter study to evaluate pulmonary function in osteogenesis imperfecta.

Pulmonary complications are a significant cause for morbidity and mortality in osteogenesis imperfecta (OI). However, to date, there have been few studies that have systematically evaluated pulmonary function in individuals with OI. We analyzed spirometry measurements, including forced vital capacity (FVC) and forced expiratory volume in the first second (FEV1 ), in a large cohort of individuals with OI (n = 217) enrolled in a multicenter, observational study. We show that individuals with the more severe form of the disease, OI type III, have significantly reduced FVC and FEV1 which do not follow the expected trends of the normal population. We also show that "normalization" of FVC and FEV1 using general population data to generate percent predicted values underestimates the pulmonary involvement in OI. Within each subtype of OI, we used linear mixed models to find potential correlations between FEV1 and FVC with the clinical variables including mobility, bisphosphonate use, and scoliosis. Our results are an important step in understanding the extent of pulmonary involvement in individuals with OI and for developing pulmonary endpoints for use in the routine patient care as well as in the investigation of new therapies.

Fatal Progressive Membranous Obliterative Bronchitis: A Sequela of Influenza?

Occlusion of the bronchial orifices by tissue-like structures is an uncommonly reported finding: it has been referred to as bronchial webs, bronchial synechiae, vanishing bronchus syndrome, or membranous obliterative bronchitis. It differs from bronchiolitis obliterans, a well-described clinical entity that involves smaller airways not visualized on bronchoscopy. Although initially only recognized as a congenital condition, later reports have described it in situations where chronic inflammation results in the irritation of the airways. Here we report a case of a woman with postinfectious bronchiectasis who developed membranous occlusion of multiple subsegmental bronchi, resulting in progressive airflow obstruction and postobstructive collapse of involved lung parenchyma. This process eventually caused her demise. It the first report of membranous occlusion of the bronchi in an adult who does not have cystic fibrosis or a history of lung transplantation. Clinicians should be aware of this entity, and further research could help illuminate its pathogenesis and management.

Anesthetic management of a large mediastinal mass for tracheal stent placement / Manejo anestésico de grande massa mediastinal para a colocação de stent traqueal

ABSTRACT The anesthetic management of patients with large mediastinal masses can be complicated due to the pressure effects of the mass on the airway or major vessels. We present the successful anesthetic management of a 64-year-old female with a large mediastinal mass that encroached on the great vessels and compressed the trachea. A tracheal stent was placed to relieve the tracheal compression under general anesthesia. Spontaneous ventilation was maintained during the perioperative period with the use of a classic laryngeal mask airway. We discuss the utility of laryngeal mask airway for anesthetic management of tracheal stenting in patients with mediastinal masses.

RESUMO O manejo anestésico de pacientes com grandes massas situadas no mediastino pode ser complicado por causa dos efeitos da pressão da massa sobre as vias aéreas ou grandes vasos. Relatamos o manejo anestésico bem-sucedido de uma paciente de 64 anos com uma grande massa mediastinal que invadiu os grandes vasos e comprimiu a traqueia. Um stent traqueal foi colocado para aliviar a compressão da traqueia, sob anestesia geral. A ventilação espontânea foi mantida durante o período perioperatório com o uso de uma máscara laríngea clássica. Discutimos a utilidade da máscara laríngea para o manejo da colocação de stent traqueal em pacientes com massas situadas no mediastino.

Critical illness in pregnancy: part I: an approach to a pregnant patient in the ICU and common obstetric disorders.

Managing critically ill obstetric patients in the ICU is a challenge because of their altered physiology, different normal ranges for laboratory and clinical parameters in pregnancy, and potentially harmful effects of drugs and interventions on the fetus. About 200 to 700 women per 100,000 deliveries require ICU admission. A systematic five-step approach is recommended to enhance maternal and fetal outcomes: (1) differentiate between medical and obstetric disorders with similar manifestations, (2) identify and treat organ dysfunction, (3) assess maternal and fetal risk from continuing pregnancy and decide if delivery/termination of pregnancy will improve outcome, (4) choose an appropriate mode of delivery if necessary, and (5) optimize organ functions for safe delivery. A multidisciplinary team including the intensivist, obstetrician, maternal-fetal medicine specialist, anesthesiologist, neonatologist, nursing specialist, and transfusion medicine expert is key to optimize outcomes. Severe preeclampsia and its complications, HELLP (hemolysis, elevated liver enzymes, and low platelets) syndrome, and amniotic fluid embolism, which cause significant organ failure, are reviewed. Obstetric conditions that were not so common in the past are increasingly seen in the ICU. Thrombotic thrombocytopenic purpura of pregnancy is being diagnosed more frequently. Massive hemorrhage from adherent placenta is increasing because of the large number of pregnant women with scars from previous cesarean section. With more complex fetal surgical interventions being performed for congenital disorders, maternal complications are increasing. Ovarian hyperstimulation syndrome is also becoming common because of treatment of infertility with assisted reproduction techniques. Part II will deal with common medical disorders and their management in critically ill pregnant women.

Critical Illness in Pregnancy: Part II: Common Medical Conditions Complicating Pregnancy and Puerperium.

The first of this two-part series on critical illness in pregnancy dealt with obstetric disorders. In Part II, medical conditions that commonly affect pregnant women or worsen during pregnancy are discussed. ARDS occurs more frequently in pregnancy. Strategies commonly used in nonpregnant patients, including permissive hypercapnia, limits for plateau pressure, and prone positioning, may not be acceptable, especially in late pregnancy. Genital tract infections unique to pregnancy include chorioamnionitis, group A streptococcal infection causing toxic shock syndrome, and polymicrobial infection with streptococci, staphylococci, and Clostridium perfringens causing necrotizing vulvitis or fasciitis. Pregnancy predisposes to VTE; D-dimer levels have low specificity in pregnancy. A ventilation-perfusion scan is preferred over CT pulmonary angiography in some situations to reduce radiation to the mother's breasts. Low-molecular-weight or unfractionated heparins form the mainstay of treatment; vitamin K antagonists, oral factor Xa inhibitors, and direct thrombin inhibitors are not recommended in pregnancy. The physiologic hyperdynamic circulation in pregnancy worsens many cardiovascular disorders. It increases risk of pulmonary edema or arrhythmias in mitral stenosis, heart failure in pulmonary hypertension or aortic stenosis, aortic dissection in Marfan syndrome, or valve thrombosis in mechanical heart valves. Common neurologic problems in pregnancy include seizures, altered mental status, visual symptoms, and strokes. Other common conditions discussed are aspiration of gastric contents, OSA, thyroid disorders, diabetic ketoacidosis, and cardiopulmonary arrest in pregnancy. Studies confined to pregnant women are available for only a few of these conditions. We have, therefore, reviewed pregnancy-specific adjustments in the management of these disorders.
