Background: The purpose of this network meta-analysis was to assess the impact of different protective ventilatory strategies on postoperative pulmonary complications (PPCs). Methods: Several databases were searched for randomized controlled trials (RCTs) that were published before October 2023 in a network meta-analysis. We assessed the effect of different lung-protective ventilation strategies on the incidence of PPCs using Bayesian network meta-analysis. Results: We included 58 studies (11610 patients) in this meta-analysis. The network meta-analysis showed that low tidal volumes (LTVs) combined with iPEEP and recruitment manoeuvres (RM) was associated with significantly lower incidence of PPCs [HTVs: OR = 0.38, 95%CrI (0.19, 0.75), LTVs: OR = 0.33, 95%CrI (0.12, 0.82)], postoperative atelectasis[HTVs: OR = 0.2, 95%CrI (0.08, 0.48), LTVs: OR = 0.47, 95%CrI (0.11, 0.93)], and pneumonia[HTVs: OR = 0.22, 95%CrI (0.09, 0.48), LTVs: OR = 0.27, 95%CrI (0.08,0.89)] than was High tidal volumes (HTVs) or LTVs. LTVs combined with medium-to-high PEEP and RM were associated with significantly lower incidence of postoperative atelectasis, and pneumonia. Conclusion: LTVs combined with iPEEP and RM decreased the incidence of PPCs, postoperative atelectasis, and pneumonia in noncardiac surgery patients. Individual PEEP-guided ventilation was the optimal lung protection ventilation strategy. The quality of evidence is moderate. Trial registration: PROSPERO identifier CRD42023399485.

Background: The effectiveness and safety of acupuncture therapy to delay lung function decline in chronic obstructive pulmonary disease (COPD) remain unclear. This study aimed to determine whether acupuncture, as an adjunctive therapy to COPD-guided medication, could prevent lung function decline. Methods: This randomised, two-centre study was conducted between February 2022 and July 2023. Men and women aged 40–80 years with COPD were recruited. Participants received active or sham acupuncture three times a week (36 sessions total). The primary outcome was the change in the percentage of forced expiratory volume for 1 s to the predicted value (FEV1%) between the baseline and after the intervention. Results: Overall, 238 participants were screened, and 74 (58 men [78.4%]; mean [standard deviation] age, 69.6 [7.2] years) were randomised into the acupuncture and sham acupuncture groups (37 per group). After the intervention, the change in FEV1% was 1.35 (95% confidence interval [CI]: -0.47 to 3.17) and -2.44 (95% CI: -4.56 to -0.33) in the acupuncture and sham acupuncture groups, respectively. The difference was -3.97 (95% CI: -6.2 to -1.74), and the adjusted difference was -3.46 (95% CI: -5.69 to -1.24, P = 0.003) between the groups. A significantly less decline was found in forced expiratory volume for 1 s in the acupuncture group. All treatment-related adverse events (acupuncture = 11, sham = 2) were mild. Conclusions: Compared with sham acupuncture, acupuncture plus medication may delay lung function decline. However, further studies with a larger sample size and longer-term follow-up are needed to clarify the effects. [ABSTRACT FROM AUTHOR]

Sinusoidal obstruction syndrome/veno‐occlusive disease (SOS/VOD) is a life‐threatening complication which can develop after haemopoietic stem cell transplantation (HSCT) and some antibody–drug conjugates. Several SOS/VOD diagnostic and management guidelines exist, with the most recent and refined being the European Society for Blood and Marrow Transplantation adult and paediatric guidelines. Timely diagnosis and effective management (including the availability of therapeutic options) significantly contribute to improved patient outcomes. In Australia and New Zealand, there is variability in clinical practice and access to SOS/VOD therapies. This review aims to summarise the current evidence for SOS/VOD diagnosis, prevention and treatment and to provide recommendations for SOS/VOD in the context of contemporary Australasian HSCT clinical practice.

Objectives Increasing studies demonstrated the importance of C5a and anti-neutrophil cytoplasmic antibody (ANCA)-induced neutrophil activation in the pathogenesis of ANCA-associated vasculitis (AAV). Sphingosine-1-phosphate (S1P) acts as a downstream effector molecule of C5a and enhances neutrophil activation induced by C5a and ANCA. The current study investigated the role of a S1P receptor modulator, FTY720, in experimental autoimmune vasculitis (EAV) and explored the immunometabolism-related mechanisms of FTY720 in modulating ANCA-induced neutrophil activation. Methods The effects of FTY720 in EAV were evaluated by quantifying haematuria, proteinuria, crescent formation, tubulointerstitial injury and pulmonary haemorrhage. RNA sequencing of renal cortex and gene enrichment analysis were performed. The proteins of key identified pathways were analysed in neutrophils isolated from peripheral blood of patients with active AAV and normal controls. We assessed the effects of FTY720 on ANCA-induced neutrophil respiratory burst and neutrophil extracellular traps formation (NETosis). Results FTY720 treatment significantly attenuated renal injury and pulmonary haemorrhage in EAV. RNA sequencing analyses of renal cortex demonstrated enhanced fatty acid oxidation (FAO) and peroxisome proliferator-activated receptor (PPAR) signalling in FTY720-treated rats. Compared with normal controls, patients with active AAV showed decreased FAO in neutrophils. FTY720-treated differentiated HL-60 cells showed increased expression of carnitine palmitoyltransferase 1a (CPT1a) and PPARα. Blocking or knockdown of CPT1a or PPARα in isolated human neutrophils and HL-60 cells reversed the inhibitory effects of FTY720 on ANCA-induced neutrophil respiratory burst and NETosis. Conclusion FTY720 attenuated renal injury in EAV through upregulating FAO via the PPARα–CPT1a pathway in neutrophils, offering potential immunometabolic targets in AAV treatment.

BACKGROUND: Mechanical ventilation is a common life-saving procedure but can lead to serious complications, including ARDS and oxygen toxicity. Nonadherence to lung-protective ventilation guidelines is common. We hypothesized that a respiratory therapist-driven mechanical ventilation bundle could increase adherence to lung-protective ventilation and decrease the incidence of pulmonary complications in the ICU. METHODS: A respiratory therapist-driven protocol was implemented on August 1, 2018, in all adult ICUs of a Midwestern academic tertiary center. The protocol targeted low tidal volume, adequate PEEP, limiting oxygen, adequate breathing frequency, and head of the bed elevation. Adherence to lung-protective guidelines and clinical outcomes were retrospectively observed in adult subjects admitted to the ICU and on ventilation for ≥ 24 h between January 2011 and December 2019. RESULTS: We included 666 subjects; 68.5% were in the pre-intervention group and 31.5% were in the post-intervention group. After adjusting for body mass index and intubation indication, a significant increase in overall adherence to lung-protective ventilation guidelines was observed in the post-intervention period (adjusted odds ratio 2.48, 95% CI 1.73-3.56). Fewer subjects were diagnosed with ARDS in the post-intervention group (adjusted odds ratio 0.22, 95% CI 0.08-0.65) than in the pre-intervention group. There was no difference in the incidence of ventilator-associated pneumonia, ventilator-free days, ICU mortality, or death within 1 month of ICU discharge. CONCLUSIONS: A respiratory therapist-driven protocol increased adherence to lung-protective mechanical ventilation guidelines in the ICU and was associated with decreased ARDS incidence.

Cryotherapy in interventional bronchoscopy is a new treatment modality which has recently been made available for the pediatric airway. Lack of experience and safety concerns have led to hesitant adaptation. The aim of this work was to elaborate on the application progress of cryotherapy in pediatric pulmonary diseases and also to assess indications, success rates, and complications of airway cryotherapy in children. In summary, cryotherapy via flexible bronchoscopy is a safe and feasible method. The application scope in pediatrics is similar to that in adults, and it is mainly used in airway obstructive diseases. However, it is primarily caused by benign conditions, and the interventional treatment mainly seeks to provide long-lasting symptomatic alleviation. Thus, prevention, treatment, and prognosis of long-term complications are issues that should be carefully considered in pediatric applications. [ABSTRACT FROM AUTHOR]

Among patients having elective abdominal surgery, how much does preoperative physiotherapy education with breathing exercise training reduce the incidence of postoperative pulmonary complications (PPCs), hospital length of stay and 12-month mortality? How stable are the treatment effects across different PPC definitions, including pneumonia? How much do the treatment effects on PPC, hospital length of stay and mortality vary within clinically relevant subgroups? Individual participant-level meta-analysis (n = 800) from two randomised controlled trials analysed with multivariable regression. Adults undergoing major elective abdominal surgery. Experimental participants received a single preoperative session with a physiotherapist within 4 weeks of surgery and educated on PPC prevention with breathing exercises and early mobilisation. They were taught breathing exercises and instructed to start them immediately on waking from surgery. The control group received no preoperative or postoperative physiotherapy, or early ambulation alone. PPC, hospital length of stay and 12-month mortality. Participants who received preoperative physiotherapy had 47% lower odds of developing a PPC (adjusted OR 0.53, 95% CI 0.34 to 0.85). This effect was stable regardless of PPC definition. Effects were greatest in participants who smoked, were aged ≤ 45 years, had abnormal body weight, had multiple comorbidities, or were undergoing bariatric or upper gastrointestinal surgery. Participants having operations ≤ 3 hours in duration were least responsive to preoperative physiotherapy. Participants with multiple comorbidities were more likely to have a shorter hospital stay if provided with preoperative physiotherapy (adjusted MD –3.2 days, 95% CI –6.2 to –0.3). Effects on mortality were uncertain. There is strong evidence to support preoperative physiotherapy in preventing PPCs after elective abdominal surgery. [ABSTRACT FROM AUTHOR]

Background: The persistently patent ductus arteriosus represents a well-known common congenital heart defect; it is uncommon in adult patients, and in any case, it debuts with atrial fibrillation. Case presentation: A 75-year-old woman suffering from persistent ductus arteriosus (PDA) was admitted to the cardiology department because of atrial fibrillation, dyspnea and exercise intolerance. A PDA was detected on echocardiography and globally assessed through ECG-gated CT angiography. Conclusions: Patent ductus arteriosus is an uncommon clinical finding in adulthood, and atrial fibrillation, as a consequence of chronic, progressive left atrial enlargement, may be the initial symptom. We describe the ECG-gated CT angiography imaging features of unknown patent ductus arteriosus in an elderly patient who debuted with atrial fibrillation. [ABSTRACT FROM AUTHOR]

The article focuses on the evolution of ventilation practices in neonatal care, particularly regarding lung protection, including the decline of chronic lung disease (CLD) in higher post-menstrual age (PMA) cohorts and the utilization of non-invasive ventilation (NIV) modes to reduce CLD risk in smaller infants, emphasizing the importance of understanding the impact of ventilatory strategies on lung development and outcomes.

We piloted the development and implementation of a multifaceted intervention package for improving respiratory health among textile workers using a pre-post design at six mills in Karachi. The intervention, implemented following a baseline survey (n = 498), included health and safety training of workers and managers, promotion of cotton dust control measures, and the provision of facemasks. Follow-up surveys were conducted at 1, 6, and 12 months post-intervention. Knowledge, attitude, and practice (KAP) scores and respiratory symptoms were assessed through a questionnaire and spirometry was conducted. The intervention was provided to 230 workers and led to an improvement in KAP scores that was more likely among workers with a higher educational status, spinners, smokers, those with a permanent employment status, working in morning shifts, and with ⩾5 years of textile experience. We found the intervention acceptable and feasible in these textile mills henceforth, trials are required to determine its effectiveness. [ABSTRACT FROM AUTHOR]

Background: Obstructive sleep apnea (OSA) commonly coexists with lung disease. However, the association between OSA components and lung function remains unclear. This study estimated STOP-BANG scores according to lung function using nationwide Korean data. Materials and Methods: Three thousand and two hundred eighty adults with available STOP-BANG scores and spirometry data were analyzed. Multivariate regression models were applied to estimate STOP-BANG scores according to lung function. Results: Approximately 28% of participants had abnormal lung function, and the characteristics were diverse. The significant factors associated with abnormal lung function included the STOP-BANG score. In multivariate regression analyses, individuals with abnormal lung function had significantly higher STOP-BANG scores than those with normal lung function (odds ratio: 1.19; 95% confidence interval: 1.10-1.29; P < 0.001), and this difference was remarkable in men. Conclusion: Our results suggest that screening and management of OSA components are warranted to prevent impaired lung function. [ABSTRACT FROM AUTHOR]

The article discusses about Benjamin Hopkins, a fourth-year medical student aspiring to become a neonatologist, emphasizing the complexity of infantile spasms diagnosis, treatment challenges, and the importance of listening to colleagues and parents.

Background and Aims: Pulmonary rehabilitation (PR) improves dyspnoea, fatigue and healthcare‐related quality of life (QoL) in patients with chronic lung disease (CLD). Non‐English‐speaking background (NESB) patients face language and cultural barriers that hinder their access to PR programmes, contributing to health disparities. Our trial aimed to demonstrate the effectiveness and feasibility of a Chinese language‐specific PR programme on lung function, functional exercise capacity and QoL measures. Methods: A prospective cohort study was conducted over a 2‐year period. Participants were enrolled in an 8‐week PR programme with biweekly sessions conducted by Chinese‐speaking physiotherapists. Baseline and post‐rehabilitation testing included pulmonary function testing, 6‐min walk test (6MWT), St. George Respiratory Questionnaire (SGQR) and Short Form Health Survey (SF‐36). Results: We enrolled 76 patients (58% male) with a median age of 77 years (interquartile range (IQR) 68–81) and achieved a completion rate of 86.8% (n = 66). CLD included chronic obstructive pulmonary disease (42%), asthma (15%) and interstitial lung disease (3%). Baseline median forced expiratory volume in 1 s (FEV1) was 1.63 L (IQR 1.17–2.05), and the median 6MWT was 282 m (IQR 232–332). Post‐intervention median 6MWT increased to 332 m (IQR 290–390), and the median FEV1 was 1.99 L (IQR 1.3–2.1). Both QoL measures (SGQR and SF‐36) showed significant improvement after intervention (P < 0.05). Conclusion: Our study demonstrates that a language‐specific PR programme is feasible, improving outcomes in NESB patients with CLD. The improvement in 6MWT and QoL measures was comparable to English‐based programmes. Ensuring equal access to healthcare programmes, regardless of cultural background or language barriers, is crucial in promoting health equity. [ABSTRACT FROM AUTHOR]

Respiratory syncytial virus (RSV) inflicts severe illness and courses of infections not only in neonates, infants, and young children, but also causes significant morbidity and mortality in older adults and in people with immunosuppression, hemato-oncologic disease, chronic lung disease, or cardiovascular disease. In June and August 2023, effective vaccines against RSV were approved for the first time by the European Medicines Agency (EMA) for the EU. The respective pivotal studies showed a very high efficacy of the vaccine in preventing severe RSV-associated respiratory infections. At this point, use of the respective vaccines is restricted to persons aged 60 years or older, according to the registration studies. We therefore recommend use of the vaccination in persons aged 60 years or older. In addition, we recommend use of the vaccination in adults of any age with severe pulmonary or cardiovascular pre-existing conditions, as well as in adults with significant immune compromise, after individual consultation with the treating physician. Cost coverage can be applied for individually with the responsible health insurance company. [ABSTRACT FROM AUTHOR]

Background: Patients undergoing open abdominal surgery are the focus of this research, namely the effect of early mobilisation on postoperative pulmonary problems. Early mobilization is proposed as a potential intervention to enhance respiratory function and reduce the risk of PPCs. Purpose: The purpose of this study is to evaluate the impact of pre-operative mobilisation on the incidence of pulmonary complications in patients undergoing open abdominal surgery. Materials and Methods: This quasi-experimental study included 50 subjects who underwent open abdominal surgery at Saveetha Medical Hospital, SIMTS. Convenient sampling was used to select the participants. Measures of oxygen saturation (SPO2) and pulmonary function (FEV1) from a spirometer were employed as functional outcome indicators. After two weeks, participants were given a post-test to record their progress. Results: Data collected before and after early mobilisation exercise were analysed using a paired t-test. The experimental group showed significant improvements in SPO2, FIM, and FEV1 (P<0.0001), indicating higher values post-intervention. Post-test demonstrated higher statistical significance compared to pre-test. Conclusion: As a result, it was shown that early mobilisation Exercise is beneficial for reducing pulmonary complications after surgery. [ABSTRACT FROM AUTHOR]

Paraquat (PQ) is a toxic herbicide to humans. Once absorbed, it accumulates in the lungs. PQ has been well documented that the generation of reactive oxygen species (ROS) is the main mechanism of its toxicity. Oxidative damage of PQ in lungs is represented as generation of cytotoxic and fibrotic mediators, interruption of epithelial and endothelial barriers, and inflammatory cell infiltration. No effective treatment for PQ toxicity is currently available. Several studies have shown that natural compounds (NCs) have the potential to alleviate PQ-induced pulmonary toxicity, due to their antioxidant and anti-inflammatory effects. NCs function as protective agents through stimulation of nuclear factor erythroid 2-related factor 2 (Nrf2)/antioxidant response element (ARE) signaling pathways. Elevation of Nrf2 levels leads to the expression of its downstream enzymes such as SOD, CAT, and HO-1. The hypothesized role of the Nrf2/ARE signaling pathway as the protective mechanism of NCs against PQ-induced pulmonary toxicity is reviewed. [ABSTRACT FROM AUTHOR]

Background: Acupressure is a branch of complementary medicine that is non-pharmacological and non-invasive. We conducted this technique to see its effect on pulmonary function in Rafsanjan Sarcheshmeh Copper Complex workers. Materials and Methods: This study was a randomized controlled clinical trial conducted on 82 workers with abnormal spirometry results. Respondents were selected by convenient sampling and then randomly divided into the two groups of 41 people. In the intervention group, after acupressure training, the participants were asked to stimulate 2 points first on one side of the body and then on the other side. The Two points were LU7 and LU9. The pressure was applied using fingers for 2 minutes at each point, at a specific time, and for 5 days by the participants themselves. In the control group, acupressure was used at ineffective points that the samples did not know about. FVC, FEV1 indices, and six-minute walk test (6MWT) in both groups were measured and compared before and after the intervention. Results: No significant difference was observed between the control and intervention groups before the study based on FVC, FEV1 and 6MWT scors. There was also no difference in the control group before and after the study based on these indices. However, in the treatment group, the FEV1 and FEV1/FVC ratios significantly increased after the intervention (P<0.05). Conclusions: Acupressure can effectively improve the functional parameters of the lungs, especially in workers who suffer from pulmonary dysfunction due to occupational diseases.

Introduction: This double blind randomized clinical trial aimed to assess effect of low tidal volume ventilation in on-pump Coronary Artery Bypass Graft (CABG) surgery on postoperative pulmonary complications. Methods: This study was conducted in Baqiyatallah Hospital from June 2021 to June 2022. 60 patients ASA class 1 and 2 CABG candidates were randomly divided into two intervention and control groups. Patients in the intervention group receive ventilation with a tidal volume (3-4 ml/kg) and several 6-8 breaths/minute. The control group doesn't receive any ventilation per the hospital routine after undergoing Cardiopulmonary Bypass (CPB). Renal and hepatic parameters are recorded before and on the first, second, and third days after surgery. Vital signs, duration of mechanical ventilation in ICU-OH, and duration of hospitalization in Intensive Care Unit (ICU) were recorded. Results: The average age of the patients was 57.43 ± 9.82 years. Thirty-nine patients (65.0%) were male. The average Hb, two days after the operation in the first group was lower than the second group (P=0.019). The average Cr, three days after the operation in the first group, was higher than the second group (P=0.037). The average SGPT, three days after the operation in the first group was higher than the second group (P=0.031). The average SGOT after surgery in the first group was higher than in the second group. The average ALK, two days and three days after surgery in the first group was higher than in the second group. The average CRP, three days after the operation in the first group was lower than the second group (P=0.001). Conclusion: This research showed no significant difference in the two groups' average operation duration, ultrafiltration volume, X Clamp duration, ICU hospitalization duration, mechanical ventilation duration, and CPB duration. Management of ventilation during cardiovascular surgery is challenging. [ABSTRACT FROM AUTHOR]

Background: There is no consensus regarding the superiority of volatile or total intravenous anesthesia (TIVA) in reducing the incidence of postoperative pulmonary complications (PPCs) after lung resection surgery (LRS). Thus, the aim of this study was to investigate the different anesthetic regimens and the incidence of PPCs in patients who underwent LRS. We hypothesized that TIVA is associated with a lower incidence of PPCs than volatile anesthesia. Methods: This was a retrospective cohort study of patients who underwent LRS at Taipei Veterans General Hospital between January 2016 and December 2020. The patients' charts were reviewed and data on patient characteristics, perioperative features, and postoperative outcomes were extracted and analyzed. The patients were categorized into TIVA or volatile anesthesia groups and their clinical data were compared. Propensity score matching was performed to reduce potential selection bias. The primary outcome was the incidence of PPCs, whereas the secondary outcomes were the incidences of other postoperative events, such as length of hospital stay (LOS) and postoperative nausea and vomiting (PONV). Results: A total of 392 patients each were included in the TIVA and volatile anesthesia groups. There was no statistically significant difference in the incidence of PPCs between the volatile anesthesia and TIVA groups. The TIVA group had a shorter LOS (p < 0.001) and a lower incidence of PONV than the volatile anesthesia group (4.6% in the TIVA group vs. 8.2% in the volatile anesthesia group; p = 0.041). However, there were no significant differences in reintubation, 30-day readmission, and re-operation rates between the two groups. Conclusions: There was no significant difference between the incidence of PPCs in patients who underwent LRS under TIVA and that in patients who underwent LRS under volatile anesthesia. However, TIVA had shorter LOS and lower incidence of PONV which may be a better choice for maintenance of anesthesia in patients undergoing LRS. [ABSTRACT FROM AUTHOR]

Background: Pregnant women with neuromuscular diseases (NMDs) often display respiratory muscle impairment which increases the risk for pulmonary complications (PCs). The aim of this study was to identify pregnant NMDs patients with pulmonary risk factors and to apply in these women non-invasive ventilation (NIV) combined with mechanical insufflation-exsufflation (MI-E) in the peri-partum period. Methods: We conducted a multicenter observational study on women with NMDs undergoing cesarean section or spontaneous labor in a network of 7 national hospitals. In these subjects we applied a protocol for screening and preventing PCs, and we evaluated PCs rate, maternal and neonatal outcome. Results: Twenty-four patients out of the 94 enrolled pregnant women were at risk for PCs and were trained or retrained to use NIV and/or MI-E before delivery. After delivery, 17 patients required NIV with or without MI-E. Despite nine out of the 24 women at pulmonary risk developed postpartum PCs, none of them needed reintubation nor tracheostomy. In addition, the average birth weight and Apgar score were normal. Only one patient without pulmonary risk factors developed postpartum PCs. Conclusion: This study showed the feasibility of applying a protocol for screening and treating pregnant NMDs women with pulmonary risk. Despite a PCs rate of 37% was observed in these patients, maternal and neonatal outcome were favorable. [ABSTRACT FROM AUTHOR]

Current estimates indicate that 50 million people are infected with food-borne trematodes. This is a significant public health problem, but still a neglected tropical disease, because the burden of disease is in rural areas, where health care is limited. Traditional ingestion of raw or poorly cooked food contaminated by unrestrained defecation maintains the cycle of disease and school-age children bear the predominant burden. Clinical patterns of infection, current means of diagnosis, treatment and treatment failure are reviewed in sections on intestinal flukes, liver flukes and lung flukes. New therapeutic approaches are emphasized. [ABSTRACT FROM AUTHOR]

Pulmonary Lymphangioleiomyomatosis (LAM) is a rare disease of the lung and lymphatic system that primarily affects women of childbearing age. LAM is a progressive disease with a terrible prognosis, which worsens over time and is extremely difficult to treat. In this study, we discuss the case of a 31-year-old woman with LAM who was initially misdiagnosed with leiomyoma and the way that led to a true diagnosis and effective treatment. Following a precise diagnosis based on comprehensive clinical data and particular immunohistochemical tests, sirolimus treatment was initiated, and the patient entirely responded to the treatment. This case report demonstrated that LAM is an uncommon condition that is challenging to diagnose, which causes its treatment to be delayed. [ABSTRACT FROM AUTHOR]

Patient-reported outcomes are based on patient (or caregiver) descriptions without direct measurement by a health care provider. To capture patient-reported outcomes, various patient-reported outcome measures (PROMs) have been created. Using PROMs has been linked to improved patient satisfaction, patient-provider communication, and clinical outcomes in many pediatric fields. Despite a long-standing history of utilizing PROMs for the evaluation and management of childhood asthma, pediatric pulmonologists lag behind other pediatric subspecialists in the use of PROMs. During the National Heart, Lung, and Blood Institute's "Defining and Promoting Pediatric Pulmonary Health" workshop, critical knowledge gaps and research opportunities in the use of PROMs for childhood respiratory health were reviewed. In particular, PROMs can be employed as screening tools in the general population for the primary or secondary prevention of pediatric lung diseases. Incorporating these PROMs into the pediatric primary care setting would be especially impactful. In addition, the use of PROMs for the evaluation and management of asthma suggests that they can be applied to other childhood respiratory diseases. Ongoing multicenter studies or national consortia that study pediatric lung diseases could be leveraged to conduct research designed to develop, validate, and assess the utility of PROMs to assess childhood respiratory health. Harnessing the electronic health record will be critical for the successful adoption of PROMs in children with lung diseases. Ultimately, an integrative approach to systematically address numerous barriers at the level of the provider, patient, and health care system will be needed to attain this goal and achieve sustainability.

Background. Diabetes impacts various organs in the body and some reports showed that the lung is also affected by diabetes, and an imbalance of inflammation and oxidative stress may participate to diabetic lung impairments. The present study is conducted to assess the impacts of Citrullus colocynthis (CC) on some aspects of these impairments. Methods. Frothy two male Wistar rats (3-4 months old and weighing 200–250 g) were used in the present research. Animals were divided into 3 groups of control, Diabetes, and Diabetes + Drug. CC was administered to diabetic rats orally. The lung tissue and BALF oxidative stress and inflammatory indices including the MDA, TAC, SOD, Gpx, TNFα, IL-6, IL-17, and IL-10 were evaluated by the ELISA method. Results. Our observations disclosed the ameliorative impacts of CC administration against oxidative stress and inflammation imbalance. Also, it was found that CC improved body weight and fasting blood sugar in rats with diabetes. Conclusion. We can conclude that the administration of CC can be effective in improving diabetic lungs in rats. [ABSTRACT FROM AUTHOR]

Objective The aim of the study is to compare the duration of oxygen therapy by using two methods of weaning from nasal continuous positive airway pressure (nCPAP) in very preterm babies. Study Design Between April 2014 and December 2016, 90 preterm <32 weeks and birthweight >1,000 g who, after at least 7 days on nCPAP, were clinically stable on <6 cm H 2 O and FiO 2 <30% were randomly assigned to weaning directly from nCPAP or with nasal high flow therapy (nHFT). In the nCPAP group, pressure was gradually reduced until the infant was stable on 4 cm H 2 O and then discontinued. In the nHFT group, flow rate was reduced until the infant was stable at 3.l pm and then discontinued. Results Eighty-four infants completed the study. There were no differences between the groups for the primary outcome, duration of oxygen therapy (median 33 [14–48] versus 28 [15–37] days; p = 0.17). The incidence of moderate-to-severe bronchopulmonary dysplasia was similar. Weaning time was shorter in the nCPAP group (p = 0.02), but the failure rate was slightly higher although non-significant. In the nHFT group, we observed better perception of patient comfort and a lower incidence of severe nasal injury. Conclusion Weaning by nHFT compared with weaning directly off nCPAP does not prolong duration of oxygen therapy. Rather, it is associated with better perceptions of infant comfort among parents and lower rates of severe nasal injury. Key Points Nasal high-flow therapy is commonly used in most neonatal intensive care unit for nCPAP weaning. Weaning by nHFT does not increase the duration of oxygen therapy. nHFT use improves the perception of infant comfort among parents. [ABSTRACT FROM AUTHOR]

The article discuss the challenges and strategies for managing chronic lung disease (CLD) in premature infants. It emphasizes the importance of lung-protective ventilation techniques in preventing moderate to severe CLD in infants born at or after 25 weeks post-menstrual age (PMA). It further highlights the characteristics of CLD, including dysplastic changes in the lungs and airways that reduce their normal function.

There have been an estimated 100 million people diagnosed with COVID-19 in the United States, with a majority of patients reporting persistent symptoms expressed as long COVID. The 2 most frequently reported long COVID symptoms are shortness of breath and fatigue. Exercise training during pulmonary rehabilitation (PR) is a successful strategy for improving the lives of people with persistent respiratory symptoms caused by a variety of lung diseases. This narrative review assessed the impact of exercise interventions on functional exercise capacity measures and related symptoms (dyspnea, fatigue) in people with long COVID over the last year. Articles were accessed through electronic databases including PubMed, Embase, CINAHL Plus with full text (EBSCO), and LitCovid. Findings for this Year in Review revealed that exercise interventions and PR show promise for improving functional exercise capacity, dyspnea, and fatigue in people with long COVID. This review supports the need for more rigorous scientific studies on the benefits of structured PR in people with long COVID who have respiratory-related symptoms. [ABSTRACT FROM AUTHOR]

The objective of the study is to review the studies on home-based pulmonary rehabilitation practices in idiopathic pulmonary fibrosis patients in the last 5 years. Home-based randomized controlled trials in idiopathic pulmonary fibrosis patients published in the PubMed database within the previous 5 years were searched. As a result of the research, a total of 5 articles were included in the study. Five home-based rehabilitation practices used in these articles were reached. Totally, 176 patients were found to have participated in these programs. As a result, patients who have difficulty accessing hospital-based rehabilitation services due to various reasons will benefit from home-based rehabilitation services. However, the content of the home-based program and the method of follow-up and supervision affect the results. [ABSTRACT FROM AUTHOR]

Background: Paediatric pulmonary diseases are the leading causes of mortality amongst children under five globally. Economic evaluations (EEs) seek to guide decision-makers on which health care interventions to adopt to reduce the paediatric pulmonary disease burden. This study aims to systematically review economic evaluations on different aspects of the inpatient management of paediatric pulmonary diseases globally. Methods: We systematically reviewed EEs published between 2010 and 2020, with a subsequent search conducted for 2020–2022. We searched PubMed, Web of Science, MEDLINE, Paediatric Economic Database Evaluation (PEDE) and the Cochrane library. We extracted data items guided by the Consolidated Health Economic Evaluation Reporting Standards (CHEERS) checklist. We collected qualitative and quantitative data which we analysed in Microsoft Excel and R software. Results: Twenty-two articles met the inclusion criteria. Six of the articles were cost-effectiveness analyses, six cost-utility analyses, two cost-minimisation analyses and eight cost analyses. Twelve articles were from high-income countries (HICs) and ten were from low- and middle-income countries (LMICs). Eight articles focused on asthma, eleven on pneumonia, two on asthma and pneumonia, and one on tuberculosis. Conclusion: Conducting more EEs for paediatric pulmonary diseases in LMICs could allow for more evidence-based decision-making to improve paediatric health outcomes. [ABSTRACT FROM AUTHOR]

Complex persistent air leak (PAL) is a clinical condition which is difficult to treat. Herein, we report the clinical case of an 18‐year‐old woman with lung and bone metastases due an ultrarare sarcoma: "round cell sarcoma non‐Ewing". She developed persistent air leaks due to an alveolopleural fistula which developed following two cycles of chemotherapy with doxorubicin. Chest drainage with suction failed to resolve the air leaks, while surgical treatment was unfeasible due to the poor clinical condition of the patient. Thus, she was reviewed for endoscopic treatment with one‐way endobronchial valves. A small valve was sequentially inserted within each segment of the right upper bronchus to occlude the entire upper lobe. Two days after the procedure, resolution of the air leaks were obtained. Chest drainage was removed 5 days later and the patient was discharged. Chemotherapy was resumed. The patient died 7 months later because of disease progression. [ABSTRACT FROM AUTHOR]

Natural disasters cause extensive damage to nature and impact on large numbers of people throughout the world. Recently, earthquakes have caused a large number of death, injured, missing, and displaced people. More than a million earthquakes occur worldwide every year, which equates to roughly two earthquakes per minute. Lung problems in earthquakes are one of the main causes of morbidity and mortality. Many pulmonary complications that occur after earthquakes are a direct result of the disaster itself. Pulmonary complications such as inhalation of dust and particulates from collapsed buildings in earthquakes, aspiration of water and pathogens due to tsunami after earthquakes, pulmonary thromboembolism, psychological effects caused by respiratory symptoms, infectious respiratory diseases and chest traumas such as pneumothorax, rib fracture, hemothorax, hemopneumothorax, diaphragmatic tear can develop after earthquakes. People in the earthquake area, search and rescue teams, and those involved in demolition and debris removal activities are at risk for asbestos exposure. The most effective solution against the lung effects of earthquakes is to take preventive and protective measures. It is very important for disaster preparedness and response teams to be aware of these problems. Respiratory problems that may arise in earthquakes were discussed in this review.

Cystic fibrosis (CF) is the most common genetic disorder in Caucasian individuals, with an incidence of 1/2,500–3,500 live births. When CF was first described in 1938, most children died in infancy. Currently, the average lifespan is 28–47.7 years. Although new breakthroughs have occurred, CF is still incurable. Both early diagnosis and treatment by multidisciplinary teams are essential to optimize short- and long-term outcomes. It is imperative for neonatal clinicians to keep up to date on the most current research, treatment, and management of CF to provide the best outcomes. This article offers clinicians an updated review of the pathophysiology and clinical manifestations of CF, as well as current evidence-based diagnostics and treatment regimens.

Background and Aim: Sulfur mustard (Mustard gas) is the most famed chemical warfare agent that caused chronic lung damage. Oxidative stress is known as a major cause of mustard lung pathogenesis. This study aimed to introduce antioxidant tablets of Iranian N-acetyl-cysteine (NAC) as an effective treatment for chronic lung damage caused by mustard gas. Methods: This study was performed as a double-blind randomized clinical trial. In the current study, 85 patients with chronic sulfur mustard lung injury from chemical warfare veterans of Qazvin province for 4 months from 2016 to 2017, randomly took one of the Iranian NAC (Oslyt®) or foreign NAC (Fluimucil®) tablets a dose of 1200 mg per day. The symptoms via breathlessness-cough and sputum scale (BCSS), modified medical research council (MMRC), COPD assessment test (CAT), rhinitis control assessment test (RCAT), and reflux symptom index (RSI) questionnaires and spirometric indices and side effects drugs were compared in groups. Results: According to the results and comparing the P-value obtained for clinical symptoms obtained through the mentioned questionnaires, it seems that in both groups of Oslyt (with 41 patients) and Fluimucil (with 44 patients), remarkably improved BCSS, MMRC, CAT, and RSI (except for RCAT) overall scores. There was no significant difference between Oslyt and Fluimucil in terms of the frequency of side effects. Conclusion: Both Iranian and foreign antioxidant drugs NAC improve the majority of clinical signs of the mustard lung. This is the first time that anti-reflux effects have been observed for antioxidants such as NAC. The Oslyt dose of 1200 mg per day is adequate for effectiveness and antioxidant effects.

Residual neuromuscular paralysis, the presence of clinically significant weakness after administration of pharmacologic neuromuscular blockade reversal, is associated with postoperative pulmonary complications and is more common in older patients. In contemporary anesthesia practice, reversal of neuromuscular blockade is accomplished with neostigmine or sugammadex. Neostigmine, an acetylcholinesterase inhibitor, increases the concentration of acetylcholine at the neuromuscular junction, providing competitive antagonism of neuromuscular blocking drug and facilitating muscle contraction. Sugammadex, a modified gamma-cyclodextrin, antagonizes neuromuscular blockade by encapsulating rocuronium and vecuronium in a one-to-one ratio for renal clearance, a pharmacokinetic property that led to the recommendation that sugammadex not be administered to those with end-stage renal disease. While data are limited, reports suggest sugammadex is efficacious and well tolerated in individuals with reduced renal function. Sugammadex provides a more rapid and complete reversal of neuromuscular blockade than neostigmine. There is also accumulating evidence that sugammadex may provide a protective effect against the development of postoperative pulmonary complications, nausea, and vomiting, and that it may have beneficial effects on the rate of bowel and bladder recovery after surgery. Accordingly, sugammadex administration is beneficial for most older patients undergoing surgery. [ABSTRACT FROM AUTHOR]

Background People with cystic fibrosis (CF) routinely suffer from recurrent sinopulmonary infections. Such infections require frequent courses of antimicrobials and often involve multidrug-resistant organisms. The goal of this study was to identify real-world evidence for the effectiveness of elexacaftor-tezacaftor-ivacaftor (ELX/TEZ/IVA) in decreasing infection-related visits and antimicrobial use in people with CF. Methods Using IBM MarketScan data, we identified 389 enrollees with CF who began taking ELX/TEZ/IVA before 1 December 2019 and were enrolled from 1 July 2019 to 14 March 2020. We also identified a comparison population who did not begin ELX/TEZ/IVA during the study period. We compared the following outcomes in the 15 weeks before and after medication initiation: total healthcare visits, inpatient visits, infection-related visits, and antimicrobial prescriptions. We analyzed outcomes using both a case-crossover analysis and a difference-in-differences analysis, to control for underlying trends. Results For the case-crossover analysis, ELX/TEZ/IVA initiation was associated with the following changes over a 15-week period: change in overall healthcare visit dates, −2.5 (95% confidence interval, −3.31 to −1.7); change in inpatient admissions, −0.16 (−.22 to −.10); change in infection-related visit dates, −0.62 (−.93 to −.31); and change in antibiotic prescriptions, −0.78 (−1.03 to −.54). Results from the difference-in-differences approach were similar. Conclusions We show a rapid reduction in infection-related visits and antimicrobial use among people with CF after starting a therapy that was not explicitly designed to treat infections. Currently, there are >30 000 people living with CF in the United States alone. Given that this therapy is effective for approximately 90% of people with CF, the impact on respiratory infections and antimicrobial use may be substantial. [ABSTRACT FROM AUTHOR]

Aim: To determine whether the injection of haemocoagulase into the biopsy tract can reduce pneumothorax and pulmonary haemorrhage after computed tomography (CT)-guided percutaneous transthoracic lung biopsy (PTLB).Materials and Methods: A retrospective study was performed involving patients with undiagnosed pulmonary lesions scheduled for PTLB between January 2020 and March 2021. Patients were assigned to the haemocoagulase group or the non-haemocoagulase group. After CT-guided biopsies were performed with a 17 G coaxial system, patients in the haemocoagulase group received a haemocoagulase injection (0.2-0.5 units) in the biopsy tract as the sheath was withdrawn. Postoperative image studies were performed to evaluate complications, including pneumothorax and pulmonary haemorrhage. Factors, including the patient's position, lesion location, and pathological results, were evaluated to determine their associations with the complications.Results: A total of 100 patients were included, with 44 men and a mean age of 53 years old. The overall incidences of pneumothorax and pulmonary haemorrhage were 15% and 13%, respectively. The incidences of pneumothorax and pulmonary haemorrhage were statistically significantly lower in the haemocoagulase group (8% and 6%, respectively) than in the non-haemocoagulase group (22% and 20%, respectively; p=0.04 and 0.03, respectively). There was no statistically significant difference in haemoptysis between the haemocoagulase (6%) and non-haemocoagulase (2%) groups (p=0.23). There were also no statistically significant associations of pneumothorax or pulmonary haemorrhage with the patients' positions, lesion location, or pathological results.Conclusion: Biopsy tract haemocoagulase injection reduced the incidences of postoperative pneumothorax and pulmonary haemorrhage after PTLB.

Objective: This study was to investigate the impact of breathing exercises on recovery in elderly patients receiving laparoscopic colorectal surgery. Design: A prospective randomized controlled trial. Setting: University hospital. Subject: A total of 264 elder patients undergoing laparoscopic colorectal surgery participated in this study. Intervention: Patients in intervention group received respiratory-related exercises based on standardized enhanced recovery after surgery strategies from admission to 90 days after surgery. The control group received perioperative standardized enhanced recovery after surgery strategies without formatted breathing exercises. Main measures: The primary outcome was the incidence of postoperative pulmonary complications. The secondary outcomes included 6-minute walking distance, surgery-related complications, length of stay, mortality postoperatively, and hospitalization costs. Results: Completion rate of breathing exercise in intervention group was over 80% till 90 days postoperatively. The incidence of postoperative pulmonary complications was lower in breathing exercises group (17/132 [12.9%] vs. 43/132 [32.6%], p < 0.001). The mean value of 6-minute walking distance increased more in intervention group compared with baseline values preoperatively (44.2 ± 4.3 vs. 3.2 ± 0.2, p < 0.001). On 90 days postoperatively, the mean value of 6-minute walking distance in breathing exercises group increased by 18.8 m compared with its baseline (557.0 ± 133.5 vs. 538.2 ± 112.7, p = 0.022), while that of control group decreased by 53.2 m from baseline (481.9 ± 102.5 vs. 535.1 ± 123.4, p < 0.001). Patients who received breathing exercises had shorter length of stay and lower hospitalization costs (p < 0.050). Conclusions: Perioperative breathing exercises helped prevent postoperative pulmonary complications and improve long-term prognosis in elderly patients undergoing laparoscopic colorectal surgery.

Traditional lung-protective ventilation strategies (LPVS) are currently used to reduce the incidence of postoperative pulmonary complications (PPCs), including low tidal volume (VT), positive end-expiratory pressure (PEEP), low inspiratory plateau pressure (Pplat), permissive hypercapnia, and recruitment maneuver (RM). However, a meta-analysis showed that high driving pressure was closely associated with the incidence of PPCs, but not with PEEP or VT, which led to the driving pressure-guided ventilation strategy. Some studies have proved that the driving pressure-guided ventilation strategy is superior to the traditional LPVS in reducing the incidence of PPCs. The purpose of this review is to present the current research progress and application of driving pressure-guided ventilation strategy. [ABSTRACT FROM AUTHOR]

Background: Many countries are introducing low‐dose computed tomography screening programmes for people at high risk of lung cancer. Effective communication strategies that convey risks and benefits, including unfamiliar concepts and outcome probabilities based on population risk, are critical to achieving informed choice and mitigating inequalities in uptake. Methods: This study investigated the acceptability of an aspect of NHS England's communication strategy in the form of a leaflet that was used to invite and inform eligible adults about the Targeted Lung Health Check (TLHC) programme. Acceptability was assessed in terms of how individuals engaged with, comprehended and responded to the leaflet. Semi‐structured, 'think aloud' interviews were conducted remotely with 40 UK screening‐naïve current and former smokers (aged 55–73). The verbatim transcripts were analysed thematically using a coding framework based on the Dual Process Theory of cognition. Results: The leaflet helped participants understand the principles and procedures of screening and fostered cautiously favourable intentions. Three themes captured the main results of the data analysis: (1) Response—participants experienced anxiety about screening results and further investigations, but the involvement of specialist healthcare professionals was reassuring; (2) Engagement—participants were rapidly drawn to information about lung cancer prevalence, and benefits of screening, but deliberated slowly about early diagnosis, risks of screening and less familiar symptoms of lung cancer; (3) Comprehension—participants understood the main principles of the TLHC programme, but some were confused by its rationale and eligibility criteria. Radiation risks, abnormal screening results and numerical probabilities of screening outcomes were hard to understand. Conclusion: The TLHC information leaflet appeared to be acceptable to the target population. There is scope to improve aspects of comprehension and engagement in ways that would support informed choice as a distributed process in lung cancer screening. Patient or Public Contribution: The insight and perspectives of patient representatives directly informed and improved the design and conduct of this study. [ABSTRACT FROM AUTHOR]

The American Academy of Pediatrics continues to provide guidance on the use of postnatal corticosteroids to manage or prevent chronic lung disease following preterm birth (formerly referred to as bronchopulmonary dysplasia). Since the last revision of such guidance in 2010, several prospective randomized trials have been published. This revision provides a review of those studies as well as updated recommendations, which include the use of systemic low-dose corticosteroid in preterm neonates with or at high risk for chronic lung disease. High-dose dexamethasone (≥0.5 mg/kg per day) is not recommended. New evidence suggests that inhaled corticosteroids may confer benefit if provided with surfactant as a vehicle, but safety data are lacking. Evidence remains insufficient to make any recommendations regarding routine use of postnatal corticosteroids in preterm infants. Neonatologists and other hospital care providers must continue to use their clinical judgment in individual patients, balancing the potential adverse effects of corticosteroid treatment with those of chronic lung disease. The decision to use postnatal corticosteroids for this purpose should be made together with the infant's parents, and the care providers should document their discussions with parents in the patient's medical record.

Informal sector mining is a growing enterprise in countries around the world providing livelihood to >40 million self-employed miners. The use of mercury in gold processing has been the sole focus of most research and public health interventions in artisanal mining. Few programs work to improve health among communities mining other commodities including sand, aggregates, quartz, lead, gemstones, coal and other materials. Although mercury is a major environmental challenge in countries with extensive gold mining, artisanal miners are also exposed to silica dust, metals and other safety hazards. The available evidence regarding hazardous exposures among self-employed miners suggests that the public health implications are much broader. There is a growing body of evidence linking exposures to silica dust to tuberculosis and other lung diseases among artisanal miners. Studies have also documented exposures to lead and other metals including arsenic, cadmium, cobalt and chromium in informal mining communities. Silica-dust exposures are higher in artisanal mining than levels reported in large industrial mining. There is ample evidence that artisanal miners are experiencing health impacts not just from mercury but also from exposures to noise, silica dust and metals. Practical, low-cost solutions have been pilot tested and shown to reduce respirable silica dust and metal exposures among miners and ore processors. Governments, development agencies and global health funders should invest in comprehensive public health programs to respond to these needs. [ABSTRACT FROM AUTHOR]
