RESUMO
Cocaine can cause a myriad of changes in the lung, which can range from bronchoconstriction to destruction of the alveolar-capillary membrane and acute lung injury. Cocaine-induced bronchospasm is a diagnosis of exclusion that should be considered when the clinical presentation of acute hypoxic and hypercapneic respiratory failure cannot be explained by chronic obstructive pulmonary disease or asthma exacerbation, anaphylaxis to food or medications, exercise, or infection. Here, we present two patients with acute hypoxic and hypercapneic respiratory failure that was ultimately attributed to cocaine use shortly prior to symptom onset.

BACKGROUND: Patients suffering from pulmonary arterial hypertension (PAH) demand frequent assessment to keep pace with a dynamic and sometimes rapidly progressive disease course. To improve our understanding of patient monitoring, we conducted a survey of pulmonary hypertension (PH) providers to establish real-world practice patterns. OBJECTIVE: To evaluate the type and frequency of patient assessment methods employed by expert PH providers following PAH diagnosis METHODS: A descriptive cross-sectional survey of PH providers across the United States was utilized to assess provider practices. Between September 14, 2017 to October 17, 2017, a survey was distributed electronically to PH experts assessing follow-up frequency and testing evaluation of patients with PAH. RESULTS: 40 (11.4%) providers completed the survey, representing cardiologists, pulmonologists, and advanced practice providers at centers who cared for an average of 95 patients per year with PAH. Follow-up testing and clinic evaluation was influenced by severity of patient illness. Frequency of re-assessment of clinic follow-up, six-minute walk test, echocardiogram, brain natriuretic peptide, and right heart catheterization in various clinical scenarios all reflected disparate practice. CONCLUSIONS: Current clinical practice patterns in the monitoring of patients with PAH are variable and do not necessarily reflect guideline-based practices, suggesting the need for further research and improved guidelines on the frequency of follow up and repeat testing.

The coronavirus of 2019 (COVID-19) disrupted delivery of healthcare. Patients with pulmonary hypertension (PH), especially pulmonary arterial hypertension (PAH), require significant resources for both diagnosis and management and are at high risk for decompensation due to disruption in their care. A survey consisting of 47 questions related to the care of patients with PH was designed by the American College of Chest Physicians 2020-2021 Pulmonary Vascular Disease (PVD) NetWork Steering Committee and sent to all members of the PVD NetWork, as well as the multiple other professional networks for PH. Participation was voluntary and anonymous. Responses were collected from November 2020 through February 2021. Ninety-five providers responded to this survey. The majority (93%) believe that care of PH patients has been affected by the pandemic. Sixty-seven percent observed decreased referrals for PH evaluation. Prior to the pandemic, only 15% used telemedicine for management of PH patients compared to 84% during the pandemic. Telemedicine was used most for follow up of selected low-risk patients (49%). While 22% respondents were completely willing to prescribe new PAH therapy via telemedicine, 11% respondents were completely unwilling. Comfort levels differed based on type of medication being prescribed. Over 90% of providers experienced disruptions in obtaining testing and 31% experienced disruptions in renewal or approval of medications. Overall, providers perceived that the COVID-19 pandemic caused significant disruption of care for PH patients. Telemedicine utilization increased but was used mostly in low-risk patients. Some providers had a decreased level of comfort prescribing PAH therapy via telemedicine encounters.

ABSTRACT: Nurse practitioners (NPs) and physician assistants (PA) are increasingly providing care to the critically ill patients in the intensive care unit. We structured a 4-month training program for our existing NPs and PAs and assessed their knowledge and skill pre and post training. The program was composed of blended didactic in critical care medicine topics, critical care simulations in simulation laboratory, and supervised critical care procedures. Formal knowledge and skill assessments were performed before and after the program to assess success in meeting predefined learning objectives. The mean preintervention medical knowledge assessment score was 3.37 ± 0.56 SD, which significantly improved to 3.86 ± 0.46 SD (p < .00001). For clinical skills for critical care procedures, the mean preintervention score was 3.10 ± 0.86 SD, which improved to 3.61 ± 0.92 SD (p < .00001). The overall knowledge (including medical knowledge and clinical skills) improved from mean 3.30 ± 0.86 SD to 3.80 ± 0.42 SD. The improvement was seen regardless of the duration of experience in critical care medicine. We concluded that structured didactics with supervised procedural training along with dedicated training in simulation laboratories, even for a short period, improves the overall knowledge and clinical skills required to work in a critical care setting.

Nontuberculous mycobacterial infection, particularly Mycobacterium avium complex (MAC), which is also known as Lady Windermere syndrome usually presents with chronic cough, typically seen in elderly caucasian women who chronically suppress the normal cough reflex. Computerized tomography of the chest in patients with MAC infection can present as a tree in bud nodules, pulmonary nodules, cavity, or consolidation. However, other coexisting diseases such as lung cancer should be kept in mind while investigating these radiographic changes in patients with suspected MAC infection, more so if they have underlying risk factors for malignancy. We present a patient with suspected MAC infection who had co-existing lung adenocarcinoma.
RESUMO
Inhaled bronchodilators and corticosteroids, when indicated, form the backbone of COPD therapy. However, over the last decade there has been an emergence of adjunct therapies in oral or inhaled form that are now part of the therapeutic approach to COPD. While these therapies have shown to be beneficial when used in the appropriate instances, there are particular considerations that need to be minded when using these therapies. This review article discussed the mechanism of roflumilast, macrolide antibiotics, other chronic antibiotic regimens, vitamin D supplementation, oral corticosteroids, n-acetylcysteine, and nebulized hypertonic saline, the clinical data behind each of these therapies, adverse events associated with therapy, and the expert recommendations for their utilization. Our goal is to provide a brief but informative and clinically useful review of commonly encountered therapies used in advanced COPD.
RESUMO
Previous studies suggest that genetic variants within genes affecting the circadian rhythm influence the development of posttraumatic stress symptoms (PTSS). In the present study, we used data from three emergency care-based cohorts to search genetic variants in circadian pathway genes previously associated with neuropsychiatric disorders for variants that influence PTSS severity. The three cohorts used included a discovery cohort of African American men and women enrolled following motor vehicle collision (n = 907) and two replication cohorts: one of multi-ethnic women enrolled following sexual assault (n = 274) and one of multi-ethnic men and women enrolled following major thermal burn injury (n = 68). DNA and RNA were collected from trauma survivors at the time of initial assessment. Validated questionnaires were used to assess peritraumatic distress severity and to assess PTSS severity 6 weeks, 6 months, and 1 year following trauma exposure. Thirty-one genetic variants from circadian rhythm genes were selected for analyses, and main effect and potential gene*stress and gene*sex interactions were evaluated. Secondary analyses assessed whether associated genetic variants affected mRNA expression levels. We found that six genetic variants across five circadian rhythm-associated genes predicted PTSS outcomes following motor vehicle collision (p < 0.05), but only two of these variants survived adjustment for multiple comparisons (False Discovery Rate < 5%). The strongest of these associations, an interaction between the PAR-zip transcription factor, thyrotroph embryonic factor (TEF) variant rs5758324 and peritraumatic distress, predicted PTSS development in all three cohorts. Further analysis of genetic variants in the genetic region surrounding TEFrs5758324 (±125,000 nucleotides) indicated that this allele showed the strongest association. Further, TEF RNA expression levels (determined via RNA-seq) were positively associated with PTSS severity in distressed individuals with at least one copy of the TEFrs5758324 minor allele. These results suggest that rs5758324 genetic variant in TEF, a regulator of clock-controlled genes and key mediator of the core circadian rhythm, influence PTSS severity in a stress-dependent manner.
