Abstract
It is not widely recognized that iron (ferrous sulfate) pill aspiration causes airway damage. Clinical diagnosis is challenging because patients are often unaware that they have aspirated a pill. The literature on this entity consists mainly of case reports. The aim of this study is to describe the clinical and pathologic features of iron pill aspiration in a series of 11 patients. A retrospective review of our pathology archives was performed to identify cases of iron pill aspiration (2013-2023). All available histologic and cytologic material was rereviewed. Clinical information was collected from the electronic medical record, and imaging studies were rereviewed. Eighteen endobronchial biopsies were identified from 11 patients (7 women and 4 men; mean age, 70 years; range, 44-82 years). Eight patients had corresponding cytology (20 specimens). Medication history was available in 9 of 11 patients, all of whom were taking iron sulfate pills. Two patients reported possible aspiration episodes; 4 had risk factors for aspiration. The diagnosis of iron pill aspiration was suspected prior to biopsy in only 1 case. Histologically, iron pill particles were yellow, golden brown, or gray, were elongated and crystal or fiber like, and stained strongly with an iron stain. Common histologic findings included mucosal ulceration, acute and/or chronic inflammation, fibrosis, and squamous metaplasia. Iron pill particles were also identified in 11 cytology specimens from 6 patients. On Papanicolaou staining, iron pill particles were yellow to golden, fiber like, refractile, and crystalline. Reactive epithelial cells, squamous metaplasia, and acute inflammation were common. The combination of iron pill intake and discolored mucosa on bronchoscopy is a potential clue to the diagnosis of iron pill aspiration. Pathologists should familiarize themselves with the appearance of iron pill particles in endobronchial biopsies and cytology specimens from the respiratory tract as this diagnosis is seldom suspected on clinical grounds, and most patients lack a history of aspiration.

Abstract
PURPOSE To analyze and present the initial findings of provider perceptions regarding the impact of the implementation of a hospital-wide Tracheostomy Rounding Team (TRT) on the delivery of tracheostomy care at the Cleveland Clinic. MATERIALS AND METHODS Based on prior literature, a novel multidisciplinary TRT was designed and implemented at the Cleveland Clinic in December of 2018. After the TRT began clinical care, a previously validated RedCap survey was administered anonymously to 358 caregivers to assess provider experience, comfort, and prior education regarding tracheostomy management. Survey results were collected, and descriptive statistics were applied. Answers were compared between providers who interacted with the TRT clinically and those who did not. RESULTS 42.9% of providers who interacted with the TRT clinically reported that the TRT improved hands-on assistance with tracheostomy care, and 36.7% reported that the TRT improved the identification of safety concerns. Similarly, 34.7% reported that the TRT improved the overall quality of tracheostomy care at the Cleveland Clinic. Providers with active exposure to the TRT additionally reported statistically higher comfort with multiple topics surrounding tracheostomy care. CONCLUSIONS The implementation of this team improved provider comfort in managing patients with tracheostomies both qualitatively and quantifiably. This intervention offered a perceived benefit to patient care at our institution. Further study of the impact of this team on quantitative patient outcomes is forthcoming.

Abstract
BACKGROUND Bronchoscopy for the diagnosis of peripheral pulmonary lesions continues to present clinical challenges, despite increasing experience using newer guided techniques. Robotic bronchoscopic platforms have been developed to potentially improve diagnostic yields. Previous studies in cadaver models have demonstrated increased reach into the lung periphery using robotic systems compared to similarly sized conventional bronchoscopes, although the clinical impact of additional reach is unclear. OBJECTIVES This study was performed to evaluate the performance of a robotic bronchoscopic system's ability to reach and access artificial tumor targets simulating peripheral nodules in human cadaveric lungs. METHODS Artificial tumor targets sized 10-30 mm in axial diameter were implanted into 8 human cadavers. CT scans were performed prior to procedures and all cadavers were intubated and mechanically ventilated. Electromagnetic navigation, radial probe endobronchial ultrasound, and fluoroscopy were used for all procedures. Robotic-assisted bronchoscopy was performed on each cadaver by an individual bronchoscopist to localize and biopsy peripheral lesions. RESULTS Sixty-seven nodules were evaluated in 8 cadavers. The mean nodule size was 20.4 mm. The overall diagnostic yield was 65/67 (97%) and there was no statistical difference in diagnostic yield for lesions <20 mm compared with lesions measuring 21-30 mm, the presence of a concentric or eccentric radial ultrasound image, or relative distance from the pleura. CONCLUSIONS The robotic bronchoscopic system was successful at biopsying 97% of peripheral pulmonary lesions 10-30 mm in size in human cadavers. These findings support further exploration of this technology in prospective clinical trials in live human subjects.

Abstract
There are several pleural diseases that occur either predominantly or exclusively in females. Most of these entities are related to obstetric or gynecological conditions. In this article, we will provide an overview of Meigs' syndrome, ovarian hyperstimulation syndrome, endometriosis, catamenial pneumothorax, catamenial hemothorax, pleural effusions that occur in the peripartum period, lymphangioleiomyomatosis, and malignant pleural effusions related to breast cancer. As most of these diagnoses are rare, considerable expertise is required to identify, diagnose, and manage these patients. The aim of this article is to present an overview of the most common forms of pleural disease affecting women, and to provide an easy reference source on current best practice.

Abstract
Rationale: The contributions of diverse cell populations in the human lung to pulmonary fibrosis pathogenesis are poorly understood. Single-cell RNA sequencing can reveal changes within individual cell populations during pulmonary fibrosis that are important for disease pathogenesis. Objectives: To determine whether single-cell RNA sequencing can reveal disease-related heterogeneity within alveolar macrophages, epithelial cells, or other cell types in lung tissue from subjects with pulmonary fibrosis compared with control subjects. Methods: We performed single-cell RNA sequencing on lung tissue obtained from eight transplant donors and eight recipients with pulmonary fibrosis and on one bronchoscopic cryobiospy sample from a patient with idiopathic pulmonary fibrosis. We validated these data using in situ RNA hybridization, immunohistochemistry, and bulk RNA-sequencing on flow-sorted cells from 22 additional subjects. Measurements and Main Results: We identified a distinct, novel population of profibrotic alveolar macrophages exclusively in patients with fibrosis. Within epithelial cells, the expression of genes involved in Wnt secretion and response was restricted to nonoverlapping cells. We identified rare cell populations including airway stem cells and senescent cells emerging during pulmonary fibrosis. We developed a web-based tool to explore these data. Conclusions: We generated a single-cell atlas of pulmonary fibrosis. Using this atlas, we demonstrated heterogeneity within alveolar macrophages and epithelial cells from subjects with pulmonary fibrosis. These results support the feasibility of discovery-based approaches using next-generation sequencing technologies to identify signaling pathways for targeting in the development of personalized therapies for patients with pulmonary fibrosis.

Abstract
BACKGROUND Damage to extracardiac structures, including the esophagus and phrenic nerve, is a known complication of cryoballoon ablation (CBA) during pulmonary vein (PV) isolation for atrial fibrillation (AF). Other adjacent structures, including the pulmonary bronchi and lung parenchyma, may be affected during CBA at the PV ostia. OBJECTIVE The purpose of this study was to prospectively study the bronchial effects of CBA in humans undergoing CBA for PV isolation. METHODS Ten patients undergoing CBA for AF under general anesthesia were enrolled in an institutional review board-approved prospective observational study. Real-time bronchoscopy was performed during cryoablation of PVs adjacent to pulmonary bronchi to monitor for thermal injury. Patients were followed for the development of respiratory complaints postprocedure. RESULTS In 7 of 10 patients (70%) and in 13 of 22 freezes (59%), ice formation was visualized in the left mainstem bronchus during CBA in the left upper PV. Ice formation was not seen in the right mainstem bronchus during right upper PV CBA. The average time to ice formation was 89 seconds. There was no significant difference (P = -.45) in average minimum balloon temperature during freezes with ice formation (-48.5°C) and freezes without ice formation (-46.3°C). No patients went on to develop respiratory complications. CONCLUSION Unrecognized ice formation occurs frequently in the left mainstem bronchus during CBA for AF. This information helps explain the source of cough and hemoptysis in some patients who undergo CBA. The long-term consequences of this novel finding and the implications for procedural safety are unknown.

Abstract
BACKGROUND AND OBJECTIVE This study evaluates two different techniques for topically anaesthetizing the airway with lidocaine during curvilinear probe endobronchial ultrasound bronchoscopy (CP-EBUS): standard injection through the working channel and spray catheter application. METHODS This was a randomized, non-blinded, single-centre pilot study. Patients with plans for CP-EBUS under moderate sedation were enrolled. All patients received nebulized lidocaine followed by posterior oropharyngeal lidocaine via atomizer and a cotton ball swab using McGill forceps. Patients were then randomly assigned to lidocaine administration using spray catheter instillation or direct application through the working channel. Lidocaine was administered in a uniform fashion by a single investigator throughout the study. The primary end-point was the number of significant coughing episodes in the first 30 min of bronchoscopy. Other end-points included lidocaine and intravenous sedation medication dosage; severe coughing session; and number of transbronchial needle aspirations. RESULTS Forty patients were included in the study: 20 patients in each group. The median numbers of coughing episodes in the first 30 min were 1 (spray catheter group) and 2 (standard injection group) (P < 0.004). Six patients in the standard installation group experienced severe coughing sessions, while there was none in the spray catheter group (P = 0.02). There were no statistical differences between the groups in the dosage of lidocaine or intravenous sedation medications used. There were a greater number of transbronchial needle aspirations performed in the spray catheter group (P = 0.008). CONCLUSIONS Lidocaine delivery via the spray catheter reduced the number of significant coughing episodes compared with standard working channel injection during CP-EBUS. Larger studies are needed to confirm these exploratory findings.

Abstract
New therapeutic strategies are needed for malignant pleural mesothelioma (MPM). We conducted a single-center, open-label, nonrandomized, pilot and feasibility trial using two intrapleural doses of an adenoviral vector encoding human IFN-α (Ad.IFN-α2b). Nine subjects were enrolled at two dose levels. The first three subjects had very high pleural and systemic IFN-α concentrations resulting in severe "flu-like" symptoms necessitating dose de-escalation. The next six patients had reduced (but still significant) pleural and serum IFN-α levels, but with tolerable symptoms. Repeated vector administration appeared to prolong IFN-α expression levels. Anti-tumor humoral immune responses against mesothelioma cell lines were seen in seven of the eight subjects evaluated. No clinical responses were seen in the four subjects with advanced disease. However, evidence of disease stability or tumor regression was seen in the remaining five patients, including one dramatic example of partial tumor regression at sites not in contiguity with vector infusion. These data show that Ad.IFN-α2b has potential therapeutic benefit in MPM and that it generates anti-tumor immune responses that may induce anatomic and/or metabolic reductions in distant tumor. Clinical trial registered with www.clinicaltrials.gov (NCT 01212367).

Abstract
PURPOSE This phase 1 dose escalation study evaluated the safety and feasibility of single-dose intrapleural IFN-beta gene transfer using an adenoviral vector (Ad.IFN-beta) in patients with malignant pleural mesothelioma (MPM) and metastatic pleural effusions (MPE). EXPERIMENTAL DESIGN Ad.IFN-beta was administered through an indwelling pleural catheter in doses ranging from 9 x 10(11) to 3 x 10(12) viral particles (vp) in two cohorts of patients with MPM (7 patients) and MPE (3 patients). Subjects were evaluated for (a) toxicity, (b) gene transfer, (c) humoral, cellular, and cytokine-mediated immune responses, and (d) tumor responses via 18-fluorodeoxyglucose-positron emission tomography scans and chest computed tomography scans. RESULTS Intrapleural Ad.IFN-beta was generally well tolerated with transient lymphopenia as the most common side effect. The maximally tolerated dose achieved was 9 x 10(11) vp secondary to idiosyncratic dose-limiting toxicities (hypoxia and liver function abnormalities) in two patients treated at 3 x 10(12) vp. The presence of the vector did not elicit a marked cellular infiltrate in the pleural space. Intrapleural levels of cytokines were highly variable at baseline and after response to gene transfer. Gene transfer was documented in 7 of the 10 patients by demonstration of IFN-beta message or protein. Antitumor immune responses were elicited in 7 of the 10 patients and included the detection of cytotoxic T cells (1 patient), activation of circulating natural killer cells (2 patients), and humoral responses to known (Simian virus 40 large T antigen and mesothelin) and unknown tumor antigens (7 patients). Four of 10 patients showed meaningful clinical responses defined as disease stability and/or regression on 18-fluorodeoxyglucose-positron emission tomography and computed tomography scans at day 60 after vector infusion. CONCLUSIONS Intrapleural instillation of Ad.IFN-beta is a potentially useful approach for the generation of antitumor immune responses in MPM and MPE patients and should be investigated further for overall clinical efficacy.

Abstract
Background A 47-year-old woman with a history of ovarian cancer and a 6-year disease-free remission presented with dyspnea and increased abdominal girth. The patient was found to have ascites and a large left pleural effusion, both of which contained malignant cells consistent with recurrent ovarian cancer. Her disease progressed despite treatment with chemotherapeutic and hormonal agents. She was then enrolled in a phase I clinical trial of adenoviral-mediated interferon beta gene therapy. Investigations Abdominal and chest CT scans, 2-[(18)F]fluoro-2-deoxyglucose PET scan, viral cultures, interferon cytokine analysis, immunophenotyping, and tumor cytotoxicity analyses. Diagnosis Stage IV ovarian cancer with malignant ascites and pleural effusion. Management Tunneled pleural catheter and intrapleural adenoviral-mediated interferon beta gene therapy.

Abstract
The clearance of sulphamethoxazole (SMX), a compound metabolised primarily by the N-acetyltransferase NAT1, is increased in cystic fibrosis (CF) patients. We assessed the activity and kinetic properties of NAT1 in lysates of peripheral blood mononuclear leukocytes (MNL) from CF (n = 17) and control (n = 22) subjects using SMX and p-aminobenzoic acid (PABA) as test substrates. The Km and Vmax values of both substrates in MNL from CF patients and control subjects were not significantly different. The acetylation of PABA (100 microM) by intact MNL from CF patients (n = 4) was not different from the observed in intact MNL from controls (n = 9) (25 +/- 3 pmol h-1 per 10(6) MNL vs 27 +/- 4 pmol h-1 per 10(6) MNL). These results suggest that there are not systemic changes in this enzyme in CF. The increased metabolic clearance of SMX may therefore be related to factors other than alterations in the level of activity of the N-acetyltransferase NAT1.

Abstract
Eighteen healthy Caucasians were evaluated for the systemic acetylation of a caffeine metabolite using the urinary caffeine metabolite ratio 5-acetylamino-6-formylamino-3-methyluracil (AFMU) to 1-methylaxanthine (1X) and for N-acetyltransferase activity in peripheral blood mononuclear leukocytes (MNL) using p-aminobenzoic acid (PABA). These are markers for systemic NAT2 and NAT1 N-acetyltransferase activities, respectively. Fourteen slow acetylators and four fast acetylators (the NAT2 polymorphism) were identified by the caffeine metabolite ratio. In slow acetylators who have decreased levels of hepatic NAT2, the AFMU/1X ratio was significantly correlated with PABA acetylation in MNL (r = 0.8; p = 0.0002). These results suggest that significant variation in the acetylation of arylamine substrates susceptible to the classical acetylator polymorphism is attributable to variation in NAT1 activity in the slow acetylator phenotype.

Abstract
The authors report the subjective results on the use of intranasal beclomethasone dipropionate in patients with cystic fibrosis. This medication has demonstrated positive results for these patients, whether polyps are present or not, and its use should be considered whenever symptoms of obstruction are present.

Abstract
We have developed methods to measure inorganic sulfate in small volumes of sweat, and compared sulfate concentrations in sweat samples from CF patients and controls. In contrast to the increases in sweat chloride, sweat sulfate concentrations in 13 CF patients were reduced to 68 +/- 24% of control values (mean +/- SD, n = 25, p less than 0.001). Sulfate concentrations in sweat may depend on sweat rates, but the rates were not significantly different in the two study groups. Since we have observed a positive correlation between sweat sulfate and sweat chloride excretion in non-CF subjects in earlier studies, we suggest that the decreased sulfate in CF sweat may bear directly on the nature of the anion permeability defect present in the ductal epithelium of the CF sweat gland.

Abstract
Possible relationships between zinc and essential fatty acid metabolism have been assessed using plasma samples obtained from 39 cystic fibrosis patients. The fatty acid composition of plasma phospholipids was analyzed by capillary gas liquid chromatography and zinc levels were measured by atomic absorption spectrometry. Computer analyses revealed positive correlations between zinc levels and (a) arachidonic acid (p less than 0.001), (b) the arachidonate/linoleate ratio (p less than 0.02), and (c) eicosatrienoic acid (n-6) (p less than 0.001). These observations suggest that conversion of linoleate to arachidonate may be modulated by zinc.

Abstract
Increased concentrations of carcinoembryonic antigen (CEA) have been reported in the sera and sputum of patients with cystic fibrosis. We have found significantly higher concentrations of CEA in both extracted and unextracted saliva of patients with cystic fibrosis compared to age-matched controls and a comparable group of patients with bronchial asthma. The mean CEA concentrations in saliva were also somewhat higher in patients with more severe respiratory disease. The concentration of CEA in the saliva of obligate heterozygotes was similar to healthy controls. This suggests that increased salivary CEA in patients with cystic fibrosis relates to the expression of the disease rather than the genetic predisposition.
