Etiquette in the Context of Death and Dying: Communication and Conversation.

Death, bereavement, and grief are experiences suffused with conflict and disenfranchisement. Intricately connected is 'etiquette' - the sense of 'should' 'must' 'right' 'wrong' 'appropriate' and 'inappropriate' individuals feel in death and bereavement situations. This paper is the first of two answering the question, 'where does etiquette arise in death and bereavement situations and what does this 'look like?'' The theme The etiquette of communication and conversation is described, highlighting the importance of early communication for resolving conflict, what is considered 'appropriate' communication and support, and the social values underpinning these. Data highlighted how the CBT concept of 'shoulding and musting' manifests in death and bereavement situations, gave insight into etiquette's role in disenfranchising grief through shaping conversations, and offered suggestions for bereavement support. Though the term 'etiquette' may be misleading out of context, the concept resonated with the bereaved community and provided language to discuss the nuances of their experiences.

A qualitative investigation of the impact that therapeutic recreational camps have on the psychological wellbeing of siblings of individuals with health conditions.

BACKGROUND: The siblings of individuals with health conditions are often overlooked, despite being at risk of experiencing psychological difficulties. There is a lack of literature investigating interventions which could promote siblings' psychological wellbeing. Therapeutic recreational (TR) camps promote self-perception and self-worth, yet there are currently no UK studies qualitatively investigating siblings' experiences of TR camps. AIMS: This study aims to understand siblings' lived experiences of attending TR camps, providing a greater depth of understanding of whether these camps have a positive impact on siblings' wellbeing. METHOD: Due to the paucity of qualitative research regarding individuals' experiences of TR camps, semi-structured interviews were conducted with eight individuals who had attended TR sibling camps. Verbatim transcripts were analysed using Interpretative Phenomenological Analysis (IPA). RESULTS: Analysis revealed three superordinate themes. The first, an environment that facilitates autonomous challenge, demonstrated the importance of siblings having a place where they felt autonomous in a fun, care-free environment. This encouraged participants to engage in challenges, feeling determined to overcome them. The second, an inclusive and supportive environment, highlighted the importance of connectedness. Facing challenges and reflecting on this within a supportive team, encouraged a sense of belonging. The final superordinate theme, a transformational journey, revealed that siblings gained determination and a positive outlook to facing challenges in daily life. Additionally, they gained self-acceptance and a positive self-image, becoming more confident with, and accepting of, their identity. CONCLUSIONS: This study presents a novel contribution to the existing literature and highlights the importance of camp providers ensuring their TR model incorporates autonomous challenge, success and reflection. These encourage positive youth development and self-determination in young people. In addition, recommendations include implementing teams, promoting positive volunteer-camper relationships and implementing reflective sessions. These recommendations could potentially enhance the positive impact that TR camps have on siblings' psychological wellbeing.

Transbronchial lung cryobiopsy in the diagnosis of interstitial lung disease.

Transbronchial cryoprobe lung biopsy (TBCLB) have recently been introduced as a safe diagnostic tool in the diagnosis of interstitial lung diseases. While we do not enough evidence its role and place as a diagnostic procedure, the technique has been adopted by many centers. In spite of expanding body of literature, there are variations in patient selection and procedural aspect of the procedure. It has been established as a safe procedure if safety measures are practiced. Diagnosis of interstitial lung diseases continuous to be challenging. Surgical lung biopsy considered as gold standard but its morbidity and mortality limit its utilization in every case. Multidisciplinary medical decision is a validated team work effort when approaching patients with interstitial lung disease.

Impact of Chest Wall Modifications and Lung Injury on the Correspondence Between Airway and Transpulmonary Driving Pressures.

OBJECTIVE: Recent interest has arisen in airway driving pressure (DP(AW)), the quotient of tidal volume (V(T)), and respiratory system compliance (C(RS)), which could serve as a direct and easily measured marker for ventilator-induced lung injury risk. We aimed to test the correspondence between DP(AW) and transpulmonary driving pressure (DP(TP))-the quotient of V(T) and lung compliance (C(L)), in response to intra-abdominal hypertension and changes in positive end-expiratory pressure during different models of lung pathology. DESIGN: Well-controlled experimental setting that allowed reversible modification of chest wall compliance (C(CW)) in a variety of models of lung pathology. SETTING: Large animal laboratory of a university-affiliated hospital. SUBJECTS: Ten deeply anesthetized swine. INTERVENTIONS: Application of intra-abdominal pressures of 0 and 20 cm H2O at positive end-expiratory pressure of 1 and 10 cm H2O, under volume-controlled mechanical ventilation in the settings of normal lungs (baseline), unilateral whole-lung atelectasis, and unilateral and bilateral lung injuries caused by saline lavage. MEASUREMENTS AND MAIN RESULTS: Pulmonary mechanics including esophageal pressure and calculations of DP(AW), DP(TP), C(RS), C(L), and C(CW). When compared with normal intra-abdominal pressures, intra-abdominal hypertension increased DP(AW), during both "normal lung conditions" (p < 0.0001) and "unilateral atelectasis" (p = 0.0026). In contrast, DP(TP) remained virtually unaffected by changes in positive end-expiratory pressure or intra-abdominal pressures in both conditions. During unilateral lung injury, both DPA(W) and DP(TP) were increased by the presence of intra-abdominal hypertension (p < 0.0001 and p = 0.0222, respectively). During bilateral lung injury, intra-abdominal hypertension increased both DP(AW) (at positive end-expiratory pressure of 1 cm H2O, p < 0.0001; and at positive end-expiratory pressure of 10 cm H2O, p = 0.0091) and DP(TP) (at positive end-expiratory pressure of 1 cm H2O, p = 0.0510; and at positive end-expiratory pressure of 10 cm H2O, p = 0.0335). CONCLUSIONS: Our data indicate that DP(AW) is influenced by reductions in chest wall compliance and by underlying lung properties. As with other measures of pulmonary mechanics that are based on unmodified P(AW), caution is advised in attempting to attribute hazard or safety to any specific absolute value of DP(AW).

Lethal factor and anti-protective antigen IgG levels associated with inhalation anthrax, Minnesota, USA.

Bacillus anthracis was identified in a 61-year-old man hospitalized in Minnesota, USA. Cooperation between the hospital and the state health agency enhanced prompt identification of the pathogen. Treatment comprising antimicrobial drugs, anthrax immune globulin, and pleural drainage led to full recovery; however, the role of passive immunization in anthrax treatment requires further evaluation.

Lung recruitment in acute respiratory distress syndrome: what is the best strategy?

PURPOSE OF REVIEW: Supporting patients with acute respiratory distress syndrome (ARDS) using a low tidal volume strategy is a standard practice in the ICU. Recruitment maneuvers can be used to augment other methods, like positive end-expiratory pressure and positioning, to improve aerated lung volume. Clinical practice varies widely, and optimal method and patient selection for recruitment maneuvers have not been determined. RECENT FINDINGS: Recent developments include experimental and clinical evidence that a stepwise extended recruitment maneuver may match the improvement in aerated lung volume seen with sustained inflation traditionally used, with less adverse effects. Positioning and other chest wall modifications may be useful adjuncts to recruitment maneuvers. In addition, evidence from clinical studies in the operating room suggests that recruitment maneuvers, as a component of an open lung strategy, may be helpful for mechanically ventilated patients with normal lungs. SUMMARY: As a component of ventilation strategy for patients with ARDS, the use of recruitment maneuvers, especially a stepwise maneuver, in addition to adequate positive end-expiratory pressure and appropriate positioning, is suggested by currently available data. Until their effect on clinical outcomes is further defined, the use of recruitment maneuvers in ARDS and other settings will continue to be guided by individual clinician experience and patient factors.

The role for endobronchial biopsy in the era of endobronchial ultrasound guided transbronchial needle aspiration for the diagnosis of sarcoidosis: a single center experience.

BACKGROUND AND AIM: Endobronchial biopsy (EBBX) has been reported to increase diagnostic yield for pulmonary sarcoidosis. The purpose of this study is to investigate the diagnostic yield for EBBX following endobronchial ultrasound guided transbronchial needle aspiration (EBUS-TBNA). METHODS: We identified a cohort of patients in the University of Minnesota Sarcoidosis Registry who had EBBx and EBUS-TBNA as part of workup for abnormal chest imaging. Data regarding demographics, biopsy approach and technique were recorded. RESULTS: Our cohort included 37 patients (53.24±9.5, Male, 22±0.57; 3.8% were African American). In these patients who had EBBX, EBUS-TBNA was performed in 100% of patients and TBBX was performed in 2 patients (5%). EBBX was positive in 9 patients (24%) and EBUS-TBNA was positive in 34 patients (92%). TBBX was diagnostic in one of two patients. EBBX was the only diagnostic tissue in 3 of the 37 patients (8%).  Conclusion: The diagnostic yield of EBBX is lower than previously reported, with only 8% of EBBXs demonstrating granulomatous inflammation. However, instrumentation used for obtaining EBBX as well as the presence of visible lesions does influence the diagnostic yield. Studies with adequate power are needed before implementing changes in clinical practice.  When performed alongside EBUS-TBNA, EBBX did not significantly add to the diagnostic yield in sarcoidosis unless visible lesions were observed.

Utility of Functional Pneumonectomy by Using Intrabronchial Valves: First Case Series and Single Center Experience.

BACKGROUND: Intrabronchial valves are approved for bronchoscopic lung volume reduction in chronic obstructive pulmonary disease patients and used for prolonged air leak. There is no data on bronchoscopic functional pneumonectomy (BFP) when treating patients with persistent air leak (PAL) or for lung volume reduction purposes. METHODS: In this observational study, 10 consecutive patients who failed to improve with traditional therapies were assessed after they underwent BFP for PAL or lung volume reduction. RESULTS: Ten patients underwent 17 valve placement procedures; 82 valves were placed (median: 8; range: 5 to 12). BFP was performed in 1 single lung transplant patient with hyperinflation of native lung compromising lung function. The rest of the patients had prolonged air leak because of various reasons; spontaneous (n=7) and postoperative (n=2). Pneumonia was the only procedure-related complication seen in 1 patient. Of patients with prolonged air leak with chest tubes (n=9), all had successful chest tube removal (median of 7 days; range: 3 to 21 d). The valves were removed within 6 weeks of chest tube removal in 6 patients. Prebronchoscopic and post-BFP actual forced expiratory volume in first second values in 2 transplant patients. CONCLUSION: PAL usually occurs in patients with severe underlying lung condition or after surgery. Management of PAL can be challenging despite pleurodesis (medical or surgical). BFP offers a minimally invasive management option.

The Feasibility of Using the "Artery Sign" for Pre-Procedural Planning in Navigational Bronchoscopy for Parenchymal Pulmonary Lesion Sampling.

BACKGROUND: Electromagnetic navigation bronchoscopy (ENB) and robotic-assisted bronchoscopy (RAB) systems are used for pulmonary lesion sampling, and utilize a pre-procedural CT scan where an airway, or "bronchus sign", is used to map a pathway to the target lesion. However, up to 40% of pre-procedural CT's lack a "bronchus sign" partially due to surrounding emphysema or limitation in CT resolution. Recognizing that the branches of the pulmonary artery, lymphatics, and airways are often present together as the bronchovascular bundle, we postulate that a branch of the pulmonary artery ("artery sign") could be used for pathway mapping during navigation bronchoscopy when a "bronchus sign" is absent. Herein we describe the navigation success and safety of using the "artery sign" to create a pathway for pulmonary lesion sampling. METHODS: We reviewed data on consecutive cases in which the "artery sign" was used for pre-procedural planning for conventional ENB (superDimension™, Medtronic) and RAB (Monarch™, Johnson & Johnson). Patients who underwent these procedures from July 2020 until July 2021 at the University of Minnesota Medical Center and from June 2018 until December 2019 at the University of Chicago Medical Center were included in this analysis (IRB #19-0011 for the University of Chicago and IRB #00013135 for the University of Minnesota). The primary outcome was navigation success, defined as successfully maneuvering the bronchoscope to the target lesion based on feedback from the navigation system. Secondary outcomes included navigation success based on radial EBUS imaging, pneumothorax, and bleeding rates. RESULTS: A total of 30 patients were enrolled in this analysis. The median diameter of the lesions was 17 mm. The median distance of the lesion from the pleura was 5 mm. Eleven lesions were solid, 15 were pure ground glass, and 4 were mixed. All cases were planned successfully using the "artery sign" on either the superDimension™ ENB (n = 15) or the Monarch™ RAB (n = 15). Navigation to the target was successful for 29 lesions (96.7%) based on feedback from the navigation system (virtual target). Radial EBUS image was acquired in 27 cases (90%) [eccentric view in 13 (43.33%) and concentric view in 14 patients (46.66%)], while in 3 cases (10%) no r-EBUS view was obtained. Pneumothorax occurred in one case (3%). Significant airway bleeding was reported in one case (3%). CONCLUSIONS: We describe the concept of using the "artery sign" as an alternative for planning EMN and RAB procedures when "bronchus sign" is absent. The navigation success based on virtual target or r-EBUS imaging is high and safety of sampling of such lesions compares favorably with prior reports. Prospective studies are needed to assess the impact of the "artery sign" on diagnostic yield.

A thematic analysis of smokers' and non-smokers' accounts of E-cigarettes.

This study explored smokers' and non-smokers' accounts of E-cigarettes. A total of 51 UK-based participants, 20 men and 31 women, responded to open-ended questions online. Inductive thematic analysis identified that the factors that influence E-cigarette behaviour and opinion in adult smokers and non-smokers are related to social context, informative sources, practical aspects and health implications. Participants presented varying accounts of E-cigarettes, suggesting that individual narratives regarding E-cigarettes are multi-faceted. This is important information for health professionals and policy makers tasked with advising on E-cigarette use.

An investigation of factors encouraging and deterring EC use: a thematic analysis of accounts from UK adults.

OBJECTIVE: This study aimed to explore E-cigarette (EC) accounts from a small sample of UK adults with varied smoking/EC experiences. This was to contribute to existing knowledge of adult perceptions and understand the factors that encourage or deter use to inform health messaging aimed at professionals, policy makers and the general public. DESIGN: Twelve participants, five men and seven women aged 23-55 years (mean age 32.43) with mixed smoking/EC backgrounds took part in face-to-face interviews, analysed using semantic-level inductive thematic analysis. RESULTS: The analysis identified three key themes. Social influence (1) relates to the understanding of the social representations of ECs. Representation and knowledge (2) captures the impact of varied EC related communication on perception. Aspects of addiction (3) conveys aspects of nicotine addiction and how this influences EC use. CONCLUSION: ECs were generally perceived as more socially acceptable than cigarettes by non-smokers, although there were varying levels of acceptability depending on the type of EC device used. There was also unanimity concerning uncertainty surrounding the devices. Behavioural/sensory elements and personal enjoyment of ECs were consistent elements that encouraged or deterred use. Although non-smokers/vapers did not use the devices, they expressed similar apprehensions to those who did.

Delivering clinical evidence-based child-parent interventions for emotional development through a digital platform: A feasibility trial.

As the prevalence of mental health conditions in childhood increases, there are growing concerns around the accessibility and scale of evidence-based support. However, barriers to referral, time commitment and engagement rates means recommended traditional group-based parenting programmes are unable to provide population level support at scale. The aim of this feasibility study was to establish whether a suite of purposively constructed animated films and digital resources could positively impact on parent and child outcomes in the early years. Families from a range of backgrounds (n = 129) participated in a mixed method evaluation of the digital programme. After completing online surveys and interviews, the test group was given access to the Embers the Dragon platform for 8 weeks whilst the control group continued as usual. 98% of test group parents showed an improvement in parental response in relation to effective parenting styles. During qualitative interviews, child participants verbally recalled an increased range of emotions and coping strategies highlighted in the programme. Digital interventions can be used to support children's emotional development independent of clinicians and may provide a solution to sustainable family psychoeducation, thereby fulfilling a preventative agenda and potentially lessening the future impact on Child and Adolescent Mental Health Services.

To Investigate the Effect of Targeted Overdilation in Balloon-Expandable Stents.

PURPOSE: Balloon-expandable stents are commonly used for the treatment of tracheobronchial strictures. We routinely perform targeted overdilation of these stents 1-2mm on initial deployment to prevent stent migration or allow foreshortening to target airway caliber; however, specific data on the effect of targeted overdilation is unknown. PATIENTS AND METHODS: We used three iCAST stents (6×22mm, 7×22mm, and 10×38mm) to perform the study. We had two sets of each size to average our results. Targeted overdilation was accomplished with Merit Elation balloons. RESULTS: The 6 × 22 and 7 × 22 stent OD increased from 6 to 11.4mm and 7 to 11.6mm. The 10 × 38 stent demonstrated minimal OD change with overdilation (OD change of 10.4 to 12.2mm). All stents demonstrated significant foreshortening with overdilation (20.2 to 5.65mm, 19.4 to 6mm, and 30.9 to 10.2mm for 6 × 22, 7 × 22, and 10 × 38, respectively). The breakpoint was seen at near twice the stated stent OD (13.5mm, 15mm, and 15mm with 6 × 22, 7 × 22 and 10 × 38, respectively). CONCLUSION: We have demonstrated that iCAST stents can increase their OD with subsequent foreshortening during targeted overdilation. This data can help facilitate decisions when selecting a particular iCAST stent for a specific airway application. Additionally, we have highlighted that balloon inflation diameter does not correspond to the actual stent OD during deployment. We believe that this data offers practical information for end-users of this stent type and additional data will be needed to corroborate our findings.

ERCP-associated infected intrahepatic pancreatic pseudocyst.

INTRODUCTION: Pancreatic pseudocysts are abnormal mature collections of pancreatic fluid that can develop in association with acute or chronic pancreatitis. Here, we share the discovery of an infected hepatic subcapsular pseudocyst of the pancreas causing septic shock following endoscopic retrograde cholangiopancreatography (ERCP). PRESENTATION OF CASE: A 55-year-old woman with ethanol-related chronic pancreatitis and biliary stricture was transferred to the ICU for hypotension 8 hours following ERCP. Examination revealed mild right upper quadrant tenderness without sign of peritonitis. Laboratory studies were notable for leukocytosis (14.6 k/L) and slightly elevated serum lipase (489 U/L). Abdominal CT scan revealed a previously undescribed subcapsular fluid collection. She underwent CT-guided percutaneous subcapsular drainage with return of opaque yellowish fluid. Fluid analysis showed elevated lipase of 62,901 U/L with cultures positive for ESBL Escherichia coli, Streptococcus constellatus, and Enterococcus faecium. DISCUSSION: A majority of pancreatic pseudocysts develop in peripancreatic regions, while, in a recent study, over a quarter of cases were found in usual sites. The management of subcapsular pseudocysts has not been standardized and often involves endoscopic or percutaneous drainage. Operative intervention is reserved for severe infection or rupture in patients with intrahepatic pseudocysts. Rarely do subcapsular pseudocysts become infected. In this case, we postulate the pseudocyst became seeded by bacteria during ERCP resulting in infection and then sepsis. CONCLUSION: This case report highlights an atypical presentation of pancreatic pseudocyst as well as a rare septic complication of ERCP.

Propionibacterium acnes Causing Mediastinal Infection following Endobronchial Ultrasound-Guided Transbronchial Needle Aspiration.

Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is now a standard of care to sample mediastinal lymph nodes and masses with high diagnostic accuracy and low complication rates. However, the procedure has potential complications that might be life-threatening. Here, we present the first case of Propionobacterium acnes (P. acnes) causing mediastinitis following EBUS-TBNA of a subcarinal lymph node.

PEEP titration: the effect of prone position and abdominal pressure in an ARDS model.

BACKGROUND: Prone position and PEEP can both improve oxygenation and other parameters, but their interaction has not been fully described. Limited data directly compare selection of mechanically "optimal" or "best" PEEP in both supine and prone positions, either with or without changes in chest wall compliance. To compare best PEEP in these varied conditions, we used an experimental ARDS model to compare the mechanical, gas exchange, and hemodynamic response to PEEP titration in supine and prone position with varied abdominal pressure. METHODS: Twelve adult swine underwent pulmonary saline lavage and injurious ventilation to simulate ARDS. We used a reversible model of intra-abdominal hypertension to alter chest wall compliance. Response to PEEP levels of 20,17,14,11, 8, and 5 cmH2O was evaluated under four conditions: supine, high abdominal pressure; prone, high abdominal pressure; supine, low abdominal pressure; and prone, low abdominal pressure. Using lung compliance determined with esophageal pressure, we recorded the "best PEEP" and its corresponding target value. Data were evaluated for relationships among abdominal pressure, PEEP, and position using three-way analysis of variance and a linear mixed model with Tukey adjustment. RESULTS: Prone position and PEEP independently improved lung compliance (P < .0001). There was no interaction. As expected, intra-abdominal hypertension increased the PEEP needed for the best lung compliance (P < .0001 supine, P = .007 prone). However, best PEEP was not significantly different between prone (12.8 ± 2.4 cmH2O) and supine (11.0 ± 4.2 cmH2O) positions when targeting lung compliance CONCLUSIONS: Despite complementary mechanisms, prone position and appropriate PEEP exert their positive effects on lung mechanics independently of each other.

Effects of whey peptides on cardiovascular disease risk factors.

Previous studies have shown that peptides derived from milk proteins can improve blood pressure. Therefore, the authors tested the blood pressure-lowering effects of a hydrolyzed whey protein supplement rich in bioactive peptides. In a 6-week controlled study, 30 prehypertensive or stage 1 hypertensive subjects (blood pressure >or=120/80 mm Hg and

Dietary and nutraceutical options for managing the hypertriglyceridemic patient.

Scientific evidence continues to accumulate regarding fasting serum triglycerides as an independent risk factor for coronary heart disease. In response, the National Cholesterol Education Program has revised the acceptable level of fasting triglycerides from <200 mg/dL to <150 mg/dL. A significant percentage of Americans suffer from hypertriglyceridemia, and considering the expanding numbers of individuals who are physically inactive, overweight, and suffering from the metabolic syndrome, it is expected that these numbers will continue to rise over the next decade. Fortunately, nutraceutical and lifestyle options have been shown to substantially and consistently reduce this risk factor. This review will focus on management options for the hypertriglyceridemic patient with an emphasis on nicotinic acid, pantethine, fish oils (eicosapentaenoic and docosahexaenoic acids), and modified carbohydrate diets.
