Meta-Analysis
Effects of external diaphragm pacing combined with conventional rehabilitation therapies in patients with chronic obstructive pulmonary disease: a systematic review and meta-analysis.
BACKGROUND
Numerous randomized controlled trials (RCTs) have reported the benefits of external diaphragm pacing combined with conventional rehabilitation therapies (EDP-CRTs) on pulmonary function and exercise capacity in patients with chronic obstructive pulmonary disease (COPD). However, evidence-based regarding its effects remains unclear.
OBJECTIVES
This systematic review and meta-analysis aimed to evaluate the effects of EDP-CRTs CRTs on patients with COPD.
DESIGN
Systematic review and meta-analysis.
DATA SOURCES AND METHODS
We performed a systematic review and meta-analysis, searching PubMed, Embase, Cochrane Central Register of Controlled Trials, Scopus, China Biology Medicine Disc, Chinese National Knowledge Infrastructure, Wan-Fang Database, and Chinese Scientific Journal Database from inception to 10 September 2023. RCTs investigating the effects of EDP-CRTs CRTs on COPD patients were included. The primary outcome was pulmonary function, including forced expiratory volume in 1 s (FEV1), the percentage of predicted values of FEV1 (FEV1%pred), and FEV1/forced vital capacity (FVC)%. Secondary outcomes included arterial blood gas analysis [the partial pressure of arterial oxygen (PaO) and the partial pressure of arterial carbon dioxide (PaCO)]; dyspnea [modified Medical Research Council Dyspnea Scale (mMRC)]; exercise capacity [6-min walking distance (6MWD)]; and quality of life [COPD assessment test (CAT)]. RevMan 5.3 software was used for meta-analysis. The quality of the included studies was assessed using the revised Cochrane Risk of Bias tool for randomized trials (RoB 2.0). The certainty of the evidence was evaluated with the Grading of Recommendations Assessment, Development, and Evaluation system.
RESULTS
In total, 13 studies/981 participants were included. The pooled results revealed significant benefits of EDP-CRTs CRTs on the FEV1 [standardized mean difference (SMD) = 1.07, 95% confidence interval (CI) = 0.58-1.56], FEV1%pred [weighted mean difference (WMD) = 6.67, 95% CI = 5.69-7.64], the FEV1/FVC% (SMD = 1.24, 95% CI = 0.48-2.00), PaO (SMD = 1.29, 95% CI = 0.74-1.84), PaCO (SMD = -1.88, 95% CI = -2.71 to -1.04), mMRC (WMD = -0.55, 95% CI = -0.65 to -0.45), 6MWD (SMD = 1.63, 95% CI = 0.85-2.42), and CAT (WMD = -1.75, 95% CI = -3.16 to -0.35), respectively. Planned subgroup analysis suggested that EDP-CRTs had a better effect on FEV1, FEV1/FVC%, 6MWD, and CAT in the duration of 2-4 weeks.
CONCLUSION
EDP-CRTs have better effects on pulmonary function, PaCO, dyspnea, exercise capacity, and quality of life in COPD patients than CRTs, and the duration to achieve the most effective treatment is 2-4 weeks.

BACKGROUND
Listeriosis is a known cause of community acquired bacterial meningitis/meningoencephalitis. It occurs more frequently in neonates, older people and immunocompromised hosts. Rarely, brain abscesses can complicate the course of infection, which poses a difficulty in the management and elevates morbidity and mortality. Myasthenia gravis is an autoimmune disease that often requires immunosuppressive treatment, which increases the risk for invasive infections.
CASE DESCRIPTION
A 75-year-old myasthenic patient, treated with prednisone and pyridostigmine, was diagnosed with invasive listeriosis. He presented with muscle weakness, dyspnea, hemiparesis and altered mental status. Brain imaging revealed multiple abscesses and blood cultures were positive for . Despite combination antibiotic therapy, he died 6 weeks after admission.
SYSTEMATIC REVIEW
Ninety-six cases of brain abscesses from 1968 to 2023 were reviewed; the majority of the patients were men, 54 years-old on average, and had at least one risk factor for invasive listeriosis. The mortality exceeded 22%. Blood cultures and CSF/abscess cultures were positive in only 79.2% and 54.6%, respectively. The most common therapeutic approach was a combination regimen that included amoxicillin or ampicillin. Only 8 patients underwent surgery, of which one died.
CONCLUSION
This case highlights the importance of as a cause of brain abscesses in populations at risk, including myasthenic patients. The challenge of diagnosing and treating this condition is aggravated by the paucity of literature and the high mortality rate.

Review
Patients with lung cancer may experience deterioration in quality of life due to adverse effects caused by their disease and its treatment. Although exercise programs have been shown to improve quality of life in certain stages of the disease, the overall impact on this population is unknown. The objective of this research was to evaluate the effect of physical activity on the self-perception of quality of life, physical wellbeing and dyspnea in lung cancer patients. Thirteen articles were included. Five meta-analyses were performed using the standardized mean difference (SMD) with 95% confidence intervals (CI) to evaluate the target outcomes. Results showed significant differences in quality of life ( = 0.01; SMD = 0.43, 95% CI = 0.10, 0.75), physical functioning ( = 0.01; SMD = 0.27, 95% CI = 0.06, 0.49) and physical wellbeing ( = 0.01; SMD = 0.37, 95% CI = 0.08, 0.67) in favour of participants who have undergone the programme compared to those who have not, without significant differences between the two groups in dyspnea. This study shows how physical activity interventions could have positive effects on physical functioning and physical wellbeing but could also be effective for improving quality of life in patients with lung cancer.

Review
The interscalene block (ISB) is the standard regional anesthesia for shoulder arthroscopy. However, the superior trunk block (STB) is an alternative with a potentially safer profile. This meta-analysis aimed to compare the incidence and degree of hemidiaphragmatic paralysis and block efficacy of these techniques. We searched MEDLINE, EMBASE, Scopus, and Cochrane databases to identify randomized controlled trials (RCTs). The main outcome was total hemidiaphragmatic paralysis. We used the Grading of Recommendation, Assessment, Development, and Evaluation (GRADE) framework to assess the certainty of evidence. Four RCTs and 359 patients were included. The STB group showed lower total hemidiaphragmatic paralysis (RR 0.07; 95% CI 0.04 to 0.14; <0.0001). The incidence of subjective dyspnea ( = 0.002) and Horner's syndrome (<0.001) was significantly lower with STB relative to ISB. There was no significant difference between groups in block duration (p = 0.67). There was a high certainty of evidence in the main outcome as per the GRADE framework. Our findings suggest that STB has a better safety profile than ISB, resulting in lower rates of hemidiaphragmatic paralysis and dyspnea while providing a similar block. Therefore, STB could be preferred to ISB, especially in patients susceptible to phrenic nerve paralysis complications.

Review
OBJECTIVE
Up to 50 % of patients recovering from pulmonary embolism (PE) experience negative long-term outcomes. Patient-reported outcome measures (PROMs) are important in identifying what matters to patients. We aimed to identify PROMs used in clinical studies and recommended by the International Consortium of Health Outcomes (ICHOM) and compare individual items with factors considered important by patients recovering from PE.
METHODS
This was a convergent mixed-methods systematic review, including quantitative studies, using PROMs and qualitative studies with non-cancer-related PE patients. Items from each PROM and qualitative findings were categorised using an International Classification of Function linking process to allow for integrated synthesis.
RESULTS
A total of 68 studies using 34 different PROMs with 657 items and 13 qualitative studies with 408 findings were included. A total of 104 individual ICF codes were used, and subsequently sorted into 20 distinct categories representing patient concerns. Identified PROMs were found to adequately cover 17/20 categories, including anxiety, fear of bleeding, stress, depression, dizziness/nausea, sleep disturbance, pain, dyspnea, fatigue, activity levels, family and friends, socializing, outlook on life, and medical treatment. PROMs from the ICHOM core set covered the same categories, except for dizziness/nausea.
CONCLUSIONS
No single PROM covered all aspects assessed as important by the PE population. PROMs recommended in the ICHOM core set cover 16/20 aspects. However, worrisome thoughts, hypervigilance around symptoms, and uncertainty of illness were experienced by patients with PE but were not covered by PROMS.

Meta-Analysis
BACKGROUND
Persistent symptoms are reported in patients who survive the initial stage of COVID-19, often referred to as "long COVID" or "post-acute sequelae of SARS-CoV-2 infection" (PASC); however, evidence on their incidence is still lacking, and symptoms relevant to pain are yet to be assessed.
METHODS
A literature search was performed using the electronic databases PubMed, EMBASE, Scopus, and CHINAL and preprint servers MedRχiv and BioRχiv through January 15, 2021. The primary outcome was pain-related symptoms such as headache or myalgia. Secondary outcomes were symptoms relevant to pain (depression or muscle weakness) and symptoms frequently reported (anosmia and dyspnea). Incidence rates of symptoms were pooled using inverse variance methods with a DerSimonian-Laird random-effects model. The source of heterogeneity was explored using meta-regression, with follow-up period, age and sex as covariates.
RESULTS
In total, 38 studies including 19,460 patients were eligible. Eight pain-related symptoms and 26 other symptoms were identified. The highest pooled incidence among pain-related symptoms was chest pain (17%, 95% confidence interval [CI], 11%-24%), followed by headache (16%, 95% CI, 9%-27%), arthralgia (13%, 95% CI, 7%-24%), neuralgia (12%, 95% CI, 3%-38%) and abdominal pain (11%, 95% CI, 7%-16%). The highest pooled incidence among other symptoms was fatigue (44%, 95% CI, 32%-57%), followed by insomnia (27%, 95% CI, 10%-55%), dyspnea (26%, 95% CI, 17%-38%), weakness (25%, 95% CI, 8%-56%) and anosmia (19%, 95% CI, 13%-27%). Substantial heterogeneity was identified (I2, 50-100%). Meta-regression analyses partially accounted for the source of heterogeneity, and yet, 53% of the symptoms remained unexplained.
CONCLUSIONS
The current meta-analysis may provide a complete picture of incidence in PASC. It remains unclear, however, whether post-COVID symptoms progress or regress over time or to what extent PASC are associated with age or sex.

Meta-Analysis
BACKGROUND
Acute heart failure (AHF) is often associated with diffuse insufficiency and arterial hypoxemia, requiring respiratory support for rapid and effective correction. We aimed to compare the effects of high-flow nasal cannula(HFNC) with those of conventional oxygen therapy(COT) or non-invasive ventilation(NIV) on the prognosis of patients with AHF.
METHODS
We performed the search using PubMed, Embase, Web of Science, MEDLINE, the Cochrane Library, CNKI, Wanfang, and VIP databases from the inception to August 31, 2023 for relevant studies in English and Chinese. We included controlled studies comparing HFNC with COT or NIV in patients with AHF. Primary outcomes included the intubation rate, respiratory rate (RR), heart rate (HR), and oxygenation status.
RESULTS
From the 1288 original papers identified, 16 studies met the inclusion criteria, and 1333 patients were included. Compared with COT, HFNC reduced the intubation rate (odds ratio [OR]: 0.29, 95% CI: 0.14-0.58, P = 0.0005), RR (standardized mean difference [SMD]: -0.73 95% CI: -0.99 - -0.47, P < 0.00001) and HR (SMD: -0.88, 95% CI: -1.07 - -0.69, P < 0.00001), and hospital stay (SMD: -0.94, 95% CI: -1.76 - -0.12, P = 0.03), and increase arterial oxygen partial pressure (PaO), (SMD: 0.88, 95% CI: 0.70-1.06, P < 0.00001) and oxygen saturation (SpO [%], SMD: 0.70, 95% CI: 0.34-1.06, P = 0.0001).
CONCLUSIONS
There were no significant differences in intubation rate, RR, HR, arterial blood gas parameters, and dyspnea scores between the HFNC and NIV groups. Compared with COT, HFNC effectively reduced the intubation rate and provided greater clinical benefits to patients with AHF. However, there was no significant difference in the clinical prognosis of patients with AHF between the HFNC and NIV groups.

Review
BACKGROUND
With new variants challenging the effectiveness of preventive measures, we are beginning to recognize the reality that COVID-19 will continue to pose an endemic threat. The manifestations of COVID-19 in lung transplant recipients during index admission are poorly understood with very few cases reported in recent lung transplant recipients. Optimal management of immunosuppression and antiviral therapy in recent transplant recipients is challenging.
METHODS
We performed a retrospective analysis identifying lung transplant recipients at our institution who contracted COVID-19 in the immediate postoperative period (within index admission). In addition, we performed a systematic review from January 2020 to August 2023 identifying all publications on the PUBMED database regarding COVID-19 infection in lung transplant recipients during index admission.
RESULTS
We report four cases of COVID-19 pneumonia in lung transplant recipients in the immediate postoperative period and we describe the clinical course, treatment options, and immunosuppression changes to manage this unique clinical problem. All patients made a full recovery and were eventually discharged home. Within our review of the literature, the most prevalent presenting symptoms were cough, dyspnea, and fatigue. Six (75%) patients decreased or held their antimetabolite. The two most common treatments were monoclonal antibodies (38%) and remdesivir (63%).
CONCLUSION
Although previous literature demonstrates that COVID-19 can be deadly in recent lung transplant recipients, rapid treatment with anti-viral therapy/immunotherapy, deescalating immunosuppression, and treatment of respiratory decompensation with Decadron was effective in our patients.

Effect of Chest Physiotherapy on Quality of Life, Exercise Capacity and Pulmonary Function in Patients with Idiopathic Pulmonary Fibrosis: A Systematic Review and Meta-Analysis.
BACKGROUND
Idiopathic pulmonary fibrosis (IPF) is one of the most deleterious diseases of the pulmonary fibrosis spectrum. Its clinical presentation includes irreversible loss of lung function, and increasing cough, dyspnea and impaired quality of life. Chest physiotherapy can improve ventilation capacity, gas exchange, dyspnea, exercise capacity and quality of life. The aim of this study was to review the evidence about chest physiotherapy in IPF, specifically meta-analyzing quality of life, exercise capacity and pulmonary function.
METHODS
A wide search was conducted in PubMed, Embase, Cochrane and Web of Science for articles included until October 2023. PROSPERO Identifier: CRD42022333496. The Downs and Black scale and the Cochrane tool were employed to evaluate quality assessments and to assess the risk of bias. Data were pooled, and a meta-analysis was conducted.
RESULTS
We selected 10 studies in which a chest physiotherapy program was performed with a total of 340 patients; of these, three articles were meta-analyzed. Significant effects in favor of chest physiotherapy were found for quality of life (MD = -8.60, 95% CI = -11.30, -5.90; < 0.00001; I = 24%), exercise capacity (MD = 37.62, 95% CI = 15.10, 60.13; = 0.001; I = 65%) and pulmonary function (MD = 7.86, 95% CI = 2.54, 13.17; = 0.004; I = 80%).
CONCLUSIONS
The systematic review showed significant results for the application of chest physiotherapy regarding pulmonary capacity, diffusion of gases and quality of life in IPF patients. The meta-analysis showed a significant improvement associated with applying chest physiotherapy in pulmonary function, exercise capacity and quality of life.

Meta-Analysis Review
BACKGROUND
Autoimmune pulmonary alveolar proteinosis (aPAP) results from impaired macrophage-mediated clearance of alveolar surfactant lipoproteins. Whole lung lavage has been the first-line treatment but recent reports suggest the efficacy of granulocyte-macrophage colony-stimulating factor (GM-CSF). We aimed to review the efficacy and safety of nebulised GM-CSF in aPAP.
METHODS
We conducted a systematic review and meta-analysis searching Embase, CINAHL, MEDLINE and Cochrane Collaborative databases (1946-1 April 2022). Studies included patients aged >18 years with aPAP receiving nebulised GM-CSF treatment and a comparator cohort. Exclusion criteria included secondary or congenital pulmonary alveolar proteinosis, GM-CSF allergy, active infection or other serious medical conditions. The protocol was prospectively registered with PROSPERO (CRD42021231328). Outcomes assessed were St George's Respiratory Questionnaire (SGRQ), 6-min walk test (6MWT), gas exchange (diffusing capacity of the lung for carbon monoxide ( ) % predicted) and arterial-alveolar oxygen gradient.
RESULTS
Six studies were identified for review and three for meta-analysis, revealing that SGRQ score (mean difference -8.09, 95% CI -11.88- -4.3, p<0.0001), functional capacity (6MWT) (mean difference 21.72 m, 95% CI -2.76-46.19 m, p=0.08), gas diffusion ( % predicted) (mean difference 5.09%, 95% CI 2.05-8.13%, p=0.001) and arterial-alveolar oxygen gradient (mean difference -4.36 mmHg, 95% CI -7.19- -1.52 mmHg, p=0.003) all significantly improved in GM-CSF-treated patients with minor statistical heterogeneity (I=0%). No serious trial-related adverse events were reported.
CONCLUSIONS
Patients with aPAP treated with inhaled GM-CSF demonstrated significant improvements in symptoms, dyspnoea scores, lung function, gas exchange and radiology indices after treatment with nebulised GM-CSF of varying duration. There is an important need to review comparative effectiveness and patient choice in key clinical outcomes between the current standard of care, whole lung lavage, with the noninvasive treatment of nebulised GM-CSF in aPAP.
