Platypnea-orthodeoxia syndrome (POS) is a rare condition characterized by dyspnea and oxygen desaturation that worsens in the upright position and improves when lying down. We report the case of a 67-year-old male who presented with a 14-month history of dyspnea in the sitting/standing position. Despite treatment for suspected asthma, his symptoms persisted, and he was referred to our hospital for further evaluation. Physical examination and arterial blood gas analysis confirmed the presence of POS, with a significant decrease in PaO and SpO when moving from a supine to an upright position. Contrast-enhanced CT showed no obvious embolism nor arteriovenous fistula, and ventilation-perfusion scintigraphy demonstrated ventilation-perfusion mismatch with a right-to-left shunt fraction of 9.4%, without any focal defect. Transthoracic echocardiography with a microbubble test demonstrated a right-to-left shunt that increased in the upright position. Transesophageal echocardiography revealed an atrial septal defect (ASD) with an atrial septal aneurysm and the presence of an inferior vena cava valve, causing a bidirectional shunt. The patient was diagnosed with POS secondary to ASD and was referred for percutaneous closure of the defect. Following the procedure, the shunt resolved, and the patient's orthostatic oxygen desaturation improved. This case highlights the importance of considering POS in patients with positional dyspnea and the value of performing diagnostic tests, such as echocardiography, in different positions to identify the underlying cause. Early recognition and appropriate management of POS can significantly improve patients' quality of life and prevent complications associated with chronic hypoxemia.

BACKGROUND
Despite deep cultural traditions, incense burning significantly impacts respiratory health. Effects of Arabian bakhour remain unknown in Saudi Arabia's Jazan region with prevalent use. This cross-sectional study addresses this gap by investigating bakhour exposure and respiratory diseases.
METHODS
This was descriptive cross-sectional study conducted in Jazan area, Saudi Arabia, from October 2023 to March 2024. A total of 1612 participants age more than 18 years, both gender and resident of Jazan Area were included. Those aged less than 18 years were excluded. SPSS v 26 was used for data analysis.
RESULTS
The sample (n=1612) had a mean age of 29±11 years and was 63% female. Bakhour use was nearly universal (98%), especially using coal (73%). Higher bakhour frequency significantly associated with increased cough (p<0.01) and dyspnea (p<0.01). Certain bakhour types linked to greater allergic rhinitis prevalence (p<0.01). Regression analysis revealed cough during bakhour use worsened respiratory health (increased respiratory score) by 3.89 times (95% CI 1.13-6.64; p=0.006) while dyspnea increased the score by 7.48 times (95% CI 4.70-10.25; p<0.001).
CONCLUSION
This study provides valuable insights into the association between Bakhour use and respiratory health in the Jazan region. The findings emphasize the need for further research and public health interventions to mitigate potential respiratory risks associated with Bakhour use.

KEY CLINICAL MESSAGE
In patients with poorly controlled diabetes, early recognition of rare fungal infections like pulmonary mucormycosis, especially when presenting with unusual complications such as broncho-esophageal fistula, is critical. Prompt intervention with antifungal therapy and consideration for surgical debridement significantly impact outcomes. Multidisciplinary management is paramount for such complex cases.
ABSTRACT
Mucormycosis is a rare fungal infection caused by the Mucorales. This infection is mostly observed among those with poorly controlled diabetes or immunodeficiency. The most common presentation of the infection among those with poorly controlled diabetes is rhino-orbit-cerebral involvement. In this case report, we provide the history and outcome of a rare case of pulmonary mucormycosis in a patient with poorly controlled diabetes who was simultaneously diagnosed with broncho-esophageal fistula. Our patient was a 32-year-old male with a history of poorly controlled diabetes. Over the months, he had complained of productive coughs and dyspnea, which had lately been joined by dysphagia. He also claimed to have lost considerable weight (10 kg) during the previous 3 months. Barium swallow showed an abnormal flow of contrast between the bronchus and esophagus, suggesting a broncho-esophageal fistula. Computed tomography of the thorax revealed a broncho-esophageal fistula between the left main bronchus (LMB) and esophagus. He had a bronchoscopy the next day, which revealed necrosis and a broncho-esophageal fistula in the LMB. A bronchial biopsy showed typical hyphae with necrotic tissue, indicating mucormycosis. The patient's antimycotic medication (liposomal amphotericin) was started and a prompt surgery consult was ordered. The patient, however, passed away from massive hemoptysis. We described a rare case of pulmonary mucormycosis with broncho-esophageal fistula in a patient with poorly controlled diabetes. The rarity of this combination highlights the associated diagnostic and treatment hurdles. Early detection, antifungal medication, as soon as possible surgical debridement of involved tissues, and a multidisciplinary approach could improve patient outcomes.

Evaluation of the predictors and frequency of silent hypoxemia in COVID-19 patients and the gap between pulse oximeter and arterial blood gas levels: A cross-sectional study.
BACKGROUND
Silent hypoxemia is when patients do not experience breathing difficulty in the presence of alarmingly low O saturation. It could cause rapid deterioration and higher mortality rates among patients, so prompt detection and identifying predictive factors could result in significantly better outcomes. This study aims to document the evidence of silent hypoxemia in patients with COVID-19 and its clinical features.
METHODS
A total of 78 hospitalized, nonintubated patients with confirmed COVID-19 infection were included in this study. Their O saturation was measured with a pulse oximeter (PO), and arterial blood gas (ABG) was taken. Demographic and clinical features were recorded. The Borg scale was used to evaluate dyspnea status, and patients with a score of less than two accompanied by O saturation of less than 94% were labeled as silent hypoxic. Univariate analysis was utilized to evaluate the correlation between variables and their odds ratio (OR) and 95% confidence interval (CI).
RESULTS
Silent hypoxemia was observed in 20 (25.6%) of the participants. The average difference between the PO and ABG methods was 4.36 ± 3.43. Based on regression analysis, dyspnea and respiratory rate demonstrated a statistically significant correlation with the O saturation difference between PO and ABG (OR: 2.05; = 0.026; 95% CI: 0.248-3.847 and OR: 0.144; = 0.048, 95% CI: 0.001-0.286). Furthermore, the Borg scale (OR: 0.29; = 0.009; 95% CI: 0.116-0.740) had a significant reverse correlation with silent hypoxia.
CONCLUSIONS
Silent hypoxemia can be a possible complication that affects some COVID-19 patients. Further care should be bestowed upon the younger population and those with underlying neurological or mental illnesses. Furthermore, the respiratory rate, pulse oximeter, and arterial blood gas O levels should be considered alongside each other.

BACKGROUND
Delayed coronary obstruction (DCO) is a rare but potentially life-threatening complication after transcatheter aortic valve implantation (TAVI) mostly affecting the left main coronary artery (LMCA) and often caused by prosthesis endothelialization or thrombus formations. Herein, we report an unusual case of a delayed LMCA-obstruction caused by a calcium nodule, which was diagnosed 4 months after TAVI due to recurrent ventricular tachycardia (VT) episodes.
CASE SUMMARY
A 73-year-old patient was readmitted to an external hospital with syncope three months after TAVI. Fast VT could be induced in electrophysiological examination, why the patient received a two-chamber implantable cardioverter defibrillator (ICD). However, after 1 month the patient was readmitted to our department with another syncope. Implantable cardioverter defibrillator records revealed multiple fast VT episodes (200-220 b.p.m.). In addition, the patient reported new-onset exertional dyspnoea (New York Class Association Stage III) and elevated high-sensitive cardiac troponin of 115 ng/L. Due to the symptoms and laboratory markers indicating potential myocardial ischaemia, a cardiac computed tomography angiography (CCTA) was performed. Cardiac computed tomography angiography revealed obstruction of the LMCA likely caused by calcium shift during TAVI. After CCTA-guided percutaneous coronary intervention, patient's course remained uneventful.
DISCUSSION
The present case report highlights the role of CCTA as a powerful non-invasive diagnostic tool in complex settings after TAVI. Delayed coronary obstruction as a procedural complication can occur after TAVI and manifest with various symptoms, including new-onset or recurrent VTs, like in the present case. Cardiac computed tomography angiography provided accurate assessment of the implanted prosthesis and detection of DCO, thus guiding the subsequent PCI.

Congenital ventricular aneurysms (CVA) are rare cardiac anomalies that have been predominantly described in the Black population. They are characterized by an akinetic ventricular protrusion that is commonly located at the basal and apical segments. Although the diagnosis is often incidental and the majority of patients are asymptomatic, life-threatening events such as persistent ventricular arrhythmias, CVA rupture, and heart failure are not uncommon. However, no standardized therapy is currently available and good outcomes have been reported with both conservative and surgical management. We report the cases of two young Black African patients with huge symptomatic CVA lesions who underwent successful surgical repair with a ventricular restoration technique. Both cases were consulted for chest pain and dyspnea. Chest X-ray and transthoracic Doppler echocardiography suggested the diagnosis. Thoracic angioscanner and thoracic magnetic resonance imaging confirmed the diagnosis. Both patients underwent successful surgery. This case report aims to revisit the diagnostic and therapeutic approach to this rare pathology, in our professional environment.

BACKGROUND
Bronchiectasis is a disease with predominantly neutrophilic inflammation. As a readily available biomarker, there is little evidence to support the use of blood neutrophil-to-lymphocyte ratio (NLR) to predict bronchiectasis exacerbation severe enough to warrant hospitalization.
METHODS
A registry-based retrospective cohort study was conducted at a in Hong Kong. Chinese patients with non-cystic fibrosis (CF) bronchiectasis were retrospectively reviewed and subsequently followed up to investigate the association of NLR and the need for hospitalization for bronchiectasis exacerbation. Data on the NLR for patients in a clinically stable state in 2018 were collected and patients followed up from 1 January 2019 to 31 December 2022. The primary outcome was the need for hospitalization due to bronchiectasis exacerbation over the next 4 years.
RESULTS
We reviewed 473 Chinese patients with non-CF bronchiectasis, of whom 94 required hospitalization for bronchiectasis exacerbation during the 4-year follow-up period. Multi-variable logistic regression adjusted for E-FACED score (Exacerbation, Forced expiratory volume in 1 s (FEV), Age, Chronic colonization, Extension, and Dyspnea score), gender, age, smoking status, and presence of co-existing chronic obstructive pulmonary disease (COPD) was conducted to compare patients with highest and lowest quartile NLR. Results revealed that those with NLR at the highest quartile were at increased risk of hospitalization for bronchiectasis exacerbation with an adjusted odds ratio (aOR) of 2.02 (95% confidence interval = 1.00-4.12, = 0.05).
CONCLUSION
Blood NLR may serve as a marker to predict the need for hospitalization due to bronchiectasis exacerbation.

The population of people in federal custody in Canada is aging. Those in custody report experiencing poorer health and high rates of chronic health conditions. Two health concerns that are disproportionately higher among those in custody are mood disorders and pain. This cross-sectional study examined health indicators associated with pain and depressive symptoms among older people (50 years and above) from multiple facilities and security levels in federal custody in Canada. Participants were assessed using the interRAI Emergency Department Contact Assessment, which captures key health indicators. Chi square and logistic regression analyses were conducted to describe the population and identify health indicators associated with mood- and pain-related outcomes, respectively. Of the 1,422 participants in this study, the majority (55%) experienced pain and at least 1 out of 5 experienced depressive symptoms. Health indicators associated with depressive symptoms and/or pain were functional measures, including mobility, managing medication(s), and dyspnea. Depressive symptoms and pain are highly prevalent among older adults in federal custody. The relationship between functional health, depressive symptoms, and pain highlights the importance of interprofessional health care and biopsychosocial intervention(s).

AIM
To develop and validate an evidence-based home pursed lip breathing (PLB) intervention protocol for improving related health outcomes (e.g., dyspnea and exercise capability) in patients with chronic obstructive pulmonary disease (COPD) and to present a detailed intervention development process.
METHODS
This home PLB intervention protocol employed phase one of the Medical Research Council (MRC) Framework for Developing and Evaluating Complex Interventions to guide the development process of the PLB intervention. We searched for research evidence on 5 July 2023 from several databases, including PubMed, Embase (via Ovid), Cochrane Library, Google Scholar and China Biology Medicine Disk (CBM). Using the content validity index, a panel of experts assessed the appropriateness of the PLB protocol.
RESULTS
We developed the preliminary home PLB intervention protocol on the basis of several underlying rationales, which encompass the extension of expiration time, enhancement of respiratory muscle strength, augmentation of tidal volume and integration of the most reliable research evidence obtained from four systematic reviews, five RCTs, five clinical trials, and 10 recommendations. We structured the PLB intervention with a designated time ratio of inspiration to expiration, set at 1:2. Additionally, this study recommends that the training parameters of the PLB intervention were as follows: three sessions per day, each lasting for 10 min, over 8 weeks. Individualised PLB training intensity adjusted the inhalation component according to each participant's tolerance level while emphasising the exhalation phase to ensure the complete expulsion of air from the lungs. The home PLB intervention protocol established strong content validity through consensus, which was reached among all panel experts. The item-level and scale-level content validity indices (CVIs) reached a maximum score of 1.0, indicating a high level of agreement and credibility in the protocol's content as evaluated by the expert panel.
CONCLUSION
An optimal evidence-based home PLB protocol has been adapted and developed to manage health-related outcomes of patients with COPD. The protocol is transparent and fully supported by relevant mechanisms, concrete evidence, recommendations and experts' consensus.
IMPLICATIONS FOR PRACTICE
In this study, we consulted patients with COPD about the 'Prepared Conditions Before PLB Practice', to ensure appropriate measures to prevent patients with COPD from potential risks. In addition, patients with COPD also contributed to the PLB exercise frequency distribution.

INTRODUCTION
COPD has become more prevalent among women, revealing a specific feminine phenotype. Women experience greater dyspnea and a more impaired quality of life. The main objective of this study was to assess the effect of gender on dyspnea during a pulmonary rehabilitation program (PRP).
METHODS
Retrospective study including COPD patients having participated in PRPs. The following data were analyzed according to gender before and after a PRP: dyspnea, quality of life, anxiety and depression, exercise capacity, muscle function (quadriceps and inspiratory muscles).
RESULTS
More than 500 patients (252 men and 252 women) were included. We did not find a significant effect of gender on the evolution of dyspnea, anxiety or depressive disorders, exercise capacity, inspiratory muscle strength, or overall quality of life score. That said, we found a possible effect on the sub-scores of the quality of life questionnaire, and regarding quadriceps strength. All criteria improved during the program in both groups.
CONCLUSIONS
During a PRP, gender does not impact the evolution of dyspnea. While women may nonetheless benefit to a greater extent in terms of quality of life sub-scores (impact, activities, symptoms) and quadriceps strength, these results still require confirmation.
