BACKGROUND: Acute bronchitis (AB) has an enormous economic impact through lost working time. We investigated whether treatment with Pelargonium extract EPs 7630 may reduce the time of inability to work. METHODS: A meta-analysis of double-blind, randomized, placebo-controlled trials with adult patients suffering from AB was performed. The average number of days of inability to work and the proportion of patients who were still unable to work after one week's treatment were assessed...

INTRODUCTION: Telomeropathies are associated with a wide range of diseases and less common combinations of various pulmonary and extrapulmonary disorders. CASE PRESENTATION: In proband with high-risk myelodysplastic syndrome and interstitial pulmonary fibrosis, whole exome sequencing revealed a germline heterozygous variant of CTC1 gene (c.1360delG). This "frameshift" variant results in a premature stop codon and is classified as likely pathogenic/pathogenic. So far, this gene variant has been described in a heterozygous state in adult patients with hematological diseases such as idiopathic aplastic anemia or paroxysmal nocturnal hemoglobinuria, but also in interstitial pulmonary fibrosis...

BACKGROUND: In COVID-19 patients undetected co-infections may have severe clinical implications associated with prolonged hospitalization, ICU admission, and mortality. Therefore, we aimed to investigate the impact of viral coinfections on the outcomes of hospitalized patients with COVID-19 in a large tertiary Saudi Arabian Hospital. METHODS: A total of 178 adult patients with confirmed SARS-CoV-2 who were hospitalized at the Armed Forces Hospital Southern Region (AFHSR), Saudi Arabia, from March 1st to June 30th 2022, were enrolled...

Interstitial lung disease (ILD) is a common manifestation of systemic autoimmune diseases. A proportion of patients with autoimmune disease associated-ILDs develop progressive pulmonary fibrosis. Regular monitoring of patients with pulmonary fibrosis is recommended to enable prompt detection of progression and initiation or escalation of therapy if needed. However, there is no established algorithm for the treatment of autoimmune disease associated-ILDs. In this article, we present three case studies that demonstrate the challenges in the diagnosis and management of patients with autoimmune disease associated-ILDs and the importance of taking a multidisciplinary approach to their care...

BACKGROUND: Acute kidney injury (AKI) poses a significant morbidity and mortality risk to critically ill COVID-19 patients. The aim of this study was to investigate the incidence, predictors, and outcomes of AKI in patients admitted to the intensive care unit (ICU) with critically ill COVID-19 pneumonia. METHODS: A multicenter retrospective study in Saudi Arabia of adult patients aged at least 18 years diagnosed with COVID-19 pneumonia and admitted to the intensive care unit between May 2020 and May 2021 was conducted...

Idiopathic pulmonary fibrosis (IPF) is a chronic disease with an unknown etiology that causes deterioration of the structure of the lung parenchyma, resulting in a severe and progressive decline in respiratory function and early mortality. IPF is essentially an incurable disease, with a mean overall survival of 5 years in approximately 20% of patients without treatment. The combination of a poor prognosis, uncertainty about the disease's progression, and the severity of symptoms has a significant impact on the quality of life of patients and their families...

The emergence of SARS-CoV-2, a novel coronavirus, caused the global Coronavirus disease of 2019 (COVID-19) pandemic. Because SARS-CoV-2 mutates rapidly, vaccines that induce immune responses against viral components critical for target cell infection strongly mitigate but do not abrogate viral spread, and disease rates remain high worldwide. Complementary treatments are therefore needed to reduce the frequency and/or severity of SARS-CoV-2 infections. OM-85, a standardized lysate of 21 bacterial strains often found in the human airways, has immuno-modulatory properties and is widely used empirically in Europe, South America and Asia for the prophylaxis of recurrent upper airway infections in adults and children, with excellent safety profiles...

BACKGROUND: Unique cognitive impairments related to chronic obstructive pulmonary diseases (COPD) have been increasingly reported. Considering the dementia risk and medication management, older patients with COPD should be evaluated for cognitive impairment. This study aimed to examine whether specific cognitive impairments related to COPD could be detected by an assessment tool using a touchscreen personal computer (PC) in older patients with COPD. METHODS: This study included 28 older male patients with COPD and 30 healthy older male individuals...

BACKGROUND: No definite consensus has been reached yet on the best treatment strategy for the large group of infants hospitalised with bronchiolitis or pneumonia. Minimal handling is often recommended, although not evaluated scientifically. There is a need to evaluate the management, as the infants often are critically affected, and the costs for society are high. The aim of this RCT was to evaluate the most common physiotherapy intervention in Sweden for this patient group, including frequent changes in body position and stimulation of physical activity, compared to standard care...

BACKGROUND: Primary ciliary dyskinesia (PCD) is a congenital disorder characterized by chronic respiratory morbidity. To date, there is no information on PCD-specific preference-based quality of life measures such as health utilities (HU). We cross-sectionally assessed HU in adult PCD patients and explored relationships with genotype, phenotype and quality of life (QOL)-PCD scales. METHODS: Diagnostic testing was performed according to international guidelines, while participants completed the visual analog scale (VAS), time trade off (TTO), standard gamble (SG), and EuroQol 5 dimensions (EQ5D) HU instruments, as well as the QOL-PCD questionnaire...

BACKGROUND: Pulmonary microvascular occlusions can aggravate SARS-CoV-2 pneumonia and result in a variable decrease in capillary blood volume (Vc). Dyspnoea may persist for several weeks after hospital discharge in many patients who have "radiologically recovered" from COVID-19 pneumonia. Dyspnoea is frequently "unexplained" in these cases because abnormalities in lung vasculature are understudied. Furthermore, even when they are identified, therapeutic options are still lacking in clinical practice, with nitric oxide (NO) supplementation being used only for severe respiratory failure in the hospital setting...

INTRODUCTION: Ovarian granulosa cell tumor is a relatively rare tumor that accounts for 2-5% of malignant ovarian tumors. This tumor progresses slowly and may recur late in life. CASE PRESENTATION: A 70-year-old woman was admitted to our hospital with a left secondary pneumothorax due to metastatic lung tumors of granulosa cell tumor. Reports of secondary pneumothorax due to granulosa cell tumor are rare. Thoracoscopic suturing and pleurodesis using talc were effective in the treatment of this pneumothorax...

BACKGROUND: Exacerbations are pivotal events in the natural history of patients with non-cystic fibrosis bronchiectasis (NCFB), since they have a negative impact on the functional evolution of these individuals. The daily symptoms of patients with NCFB show great variability, which negatively affects their self-perception of symptoms and exacerbations. The aim of this study was to identify daily symptoms in patients with NCFB, and to investigate whether there is a correlation between the frequency of self-reported exacerbations and events defined according to the criteria established in the literature to define exacerbation in bronchiectasis...

BACKGROUND: The objective of this study was to assess clinical and imaging features of rheumatoid arthritis (RA) associated with interstitial lung disease (ILD), (RA-ILD) group, in comparison to RA without ILD (RA-C) and to identify the associated factors to ILD. METHODS: This was a retrospective comparative study (from June 2015 to March 2022) including RA patients aged ≥18 years. The RA-C control group was matched according to age (±2 years), gender, and RA duration (±2 years)...

BACKGROUND: Several studies have demonstrated gender influence on asthma prevalence, being higher among males during early childhood. Little is known about the impact of gender and age on asthma exacerbation characteristics in pediatrics. This study aimed to determine the differences in acute asthma between males and females in three different age groups regarding perinatal characteristics of asthmatic patients, comorbidities, medication adherence, level of blood eosinophils, and pattern of hospitalization...

BACKGROUND: Tuberculosis (TB) control remains a critical public health problem worldwide. Rapid diagnosis and proper treatment are beneficial for the effective control of tuberculosis transmission. Diagnostic challenges arise when a patient has a clinical and radiological suspicion of tuberculosis but cannot produce sputum, sputum acid-fast bacilli, or Xpert Mycobacterium tuberculosis /rifampicin (Xpert MTB/RIF) is negative, resulting in suboptimal management. As a result, more invasive techniques must be used on these patients to establish the diagnosis...

INTRODUCTION: The relationship between asthma and obstructive sleep apnea (OSA) is a widely debated topic in the scientific literature with the controversy surrounding the bi-directional nature of the correlation. CASE PRESENTATION: We report the case of a 59-year-old male being affected by severe allergic eosinophilic asthma and severe OSA (apnea-hypopnea index [AHI] 32 ev·hr-1 ). Due to a clinical worsening of asthma (aggravation of dyspnea, chest constriction and night-time respiratory symptoms), despite the optimal therapy for asthma and recurrent administration of systemic corticosteroids, we have added-on treatment with benralizumab (monoclonal anti-interleukin 5 antibody)...

Background: During SARS-CoV-2 infection, diffuse alveolar damage and pulmonary microvascular abnormalities are critical events that result in gas exchange disorders of varying severity and duration. The only measure of carbon monoxide (CO) diffusing capacity (DLCO ) is unable to distinguish the alveolar from the vascular side of present and residual diffusive abnormalities, and measure of nitric oxide (NO) diffusing capacity (DLNO ) is also recommended. Dyspnoea, despite being understudied, persists in a significant proportion of patients for several weeks after hospital discharge...

Severe asthma patients' life is heavily influenced by the disease, which has impact on personal and professional choices or general lifestyle. Despite the available tools to help physicians investigating the patient-reported outcomes there is a need for a more standardised and structured approach to include the evaluation of quality of life together with the emotions of patients into the routine clinical interaction. We hereby report the use of an active listening and insight approach to understand the emotions of patients with severe asthma through dedicated in-person meetings involving a group of patients with their doctors, caregivers and an external moderator...

The length of stay in the hospital for COVID-19 can aid in understanding the disease's prognosis. Thus, the goal of this study was to collectively estimate the hospital length of stay (LoS) in COVID-19 hospitalized individuals. To locate related studies, international databases (including Google Scholar, Science Direct, PubMed, and Scopus) were searched. The I2 index, the Cochran Q test, and T2 were used to analyze study heterogeneity. The mean LoS in COVID- 19 hospitalized patients was estimated using a random-effects model...
