BACKGROUND
Swimming induced pulmonary oedema is an uncommon occurrence and usually presents during strenuous distance swimming in cold water. The prevalence is most likely underreported and the underlying mechanisms are controversial. The purpose of this study was to summarize the evidence with regards to prevalence, pathophysiology and treatment of swimming induced pulmonary oedema in endurance athletes.
METHODS
Medline, Embase, Scopus and Google Scholar were searched and level I-IV from 1970 to 2017 were included. For clinical studies, only publications reporting on swimming-induced pulmonary oedema were considered. Risk of bias was assessed with the ROBINS-I tool, and the quality of evidence was assessed with the Cochrane GRADE system. For data synthesis and analysis, a best evidence synthesis was used.
RESULTS
A total of 29 studies were included (174 athletes). The most common symptom was cough, dyspnoea, froth and haemoptysis. The risk of bias for the clinical studies included 13 with moderate risk, 3 with serious, and 4 with critical. Four of the pathophysiology studies had a moderate risk, 3 a serious risk, and 1 a critical risk of bias. A best evidence analysis demonstrated a strong association between cold water immersion and in increases of CVP (central venous pressure), MPAP (mean pulmonary arterial pressure), PVR (peripheral vascular resistance) and PAWP (pulmonary arterial wedge pressure) resulting in interstitial asymptomatic oedema.
CONCLUSION
The results of this study suggest a moderate association between water temperature and the prevalence of SIPE. The presence of the clinical symptoms cough, dyspnoea, froth and haemoptysis are strongly suggestive of SIPE during or immediately following swimming. There is only limited evidence to suggest that there are pre-existing risk factors leading to SIPE with exposure to strenuous physical activity during swimming. There is strong evidence that sudden deaths of triathletes are often associated with cardiac abnormalities.

Meta-Analysis Review
AIMS
Lung ultrasound (LUS) has been rapidly developed to evaluate pulmonary extravascular fluid. A systematic review was conducted to study the dynamic changes of LUS findings of pulmonary congestion before and after hemodialysis and examine the application of LUS for the prognosis of hemodialysis patients.
MATERIAL AND METHODS
This study searched online databases for articles on hemodialysis patients that used LUS to evaluate dynamic changes during hemodialysis or prognosis. Articles published in English or Chinese until September 2021 with ≥30 patients were included in this study.
RESULTS
Of the 1329 articles, 14 met the inclusion criteria: 9 reported dynamic changes during dialysis in LUS (438 patients), and 5 reported the prognosis of hemodialysis patients in LUS (1274 patients). As indicated by a further meta-analysis, eight studies found that the combined standardized effect size was -0.74. The all-cause mortality rate of the dialysis patient group with high B-line scores was three times that of the dialysis patient group with low B-line scores. In dialysis patients, no difference was found between the LUS guided treatment and the conventional care in reducing the all-cause mortality (HR=0.92 95%CI: 0.67-1.27) and cardiovascular events (HR=0.98 95%CI: 0.72 -1.34).
CONCLUSIONS
LUS can be used to effectively evaluate the volume status of hemodialysis patients in real time. The level of B-line before dialysis is significantly correlated with the poor prognosis. However, compared with the routine nursing group, the treatment of hemodialysis patients with LUS-guided volume management cannot effectively reduce mortality and cardiovascular events.

Review
Cardiogenic pulmonary edema (CPE) is a clinical health problem that induces impaired gas exchange, dyspnea and hypoxia. This serious condition results in acute respiratory failure and high mortality rate. This article suggests an effective approach to CPE patient clinical symptom assessment and management. In accordance with evidence-based methods, we searched Cochrane, CINAHL and ScienceDirect and identified four Oxford Ia or Ib reports that employed a randomized controlled trial, systematic review and meta-analysis. Results suggest that prompt application of a non-invasive positive ventilator, especially continuous positive or bi-level positive airway pressure, can help patients reduce intubation risks, ICU stay days, and mortality rates. The authors hope to see more clinical trials on this topic to support evidence-based clinical nursing care.

Meta-Analysis Review
BACKGROUND
Pulmonary arterial hypertension (PAH) is a progressive disorder characterized by hypertension in the pulmonary arteries. PAH leads to symptoms such as shortness of breath, dizziness, leg edema and chest pain, impacting heavily on quality of life. The aim of this systematic review and meta-analysis was to determine the effect of exercise training to improve physical fitness and functionality in patients with PAH.
METHODS
A search was conducted for controlled trials using the databases Medline, Embase, SPORT Discus and Cochrane Central Register of Controlled Trials. Studies were included if at least 80% of the participants presented with group 1 PAH and if the intervention consisted of an exercise training program of at least 3 weeks duration. Data were extracted on study quality, participant and exercise intervention characteristics, and outcomes. Data were pooled by the generic inverse variance method using random effect models and were expressed as weighted means and 95% confidence intervals (CI).
RESULTS
Of 110 identified abstracts, 5 studies with 106 patients (exercise: 53; control: 53; mean age 49.7 years) were included. Disease severity ranged from mild to severe; 96 patients suffered from PAH, 10 patients had chronic thromboembolic pulmonary hypertension. Exercise training led to an increase in 6 minute walk distance (72.5 m; 95% CI 46.0 m to 99.1 m; p < 0.0001) and peak oxygen uptake (2.16 mL/kg/min; 95% CI 2.16 to 3.93; p = 0.02). No severe adverse events during exercise were reported.
CONCLUSIONS
Our findings suggest that an exercise training program positively influences exercise tolerance and functional capacity in patients with PAH.

Meta-Analysis Review
BACKGROUND
Discriminating acute lung injury (ALI) or acute respiratory distress syndrome (ARDS) from cardiogenic pulmonary edema (CPE) is often challenging. This systematic review examines studies using biomarkers or images to distinguish ALI/ARDS from CPE.
METHODS
Three investigators independently identified studies designed to distinguish ALI/ARDS from CPE in adults. Studies were identified from PubMed, and the Cochrane Central Register of Controlled Trials database until July 3, 2017.
RESULTS
Of 475 titles and abstracts screened, 38 full texts were selected for review, and we finally included 24 studies in this systematic review: 21 prospective observational studies, two retrospective observational studies, and one retrospective combined with prospective study. These studies compared various biomarkers to differentiate subjects with ALI/ARDS and in those with CPE, and 13 calculated the area under the receiver operator characteristic curve (AUC). The most commonly studied biomarker (four studies) was brain natriuretic peptide (BNP) and the discriminatory ability ranged from AUC 0.67-0.87 but the timing of measurement varied. Other potential biomarkers or tools have been reported, but only as single studies.
CONCLUSIONS
There were no identified biomarkers or tools with high-quality evidence for differentiating ALI/ARDS from CPE. Combining clinical criteria with validated biomarkers may improve the predictive accuracy.

Review
Graduated compression stockings as a prophylactic measure in venous thromboembolism and edema of lower limbs triggered by air travel: a systematic review of clinical trials.
The increase in duration and frequency of flights has led to an increase in the prevalence of venous thromboembolism among airline passengers. This study assesses the efficacy of graduated compression stockings for prevention of venous thromboembolism triggered by flights lasting more than 3 hours. The design is a systematic review of clinical trials. The methodological quality of studies and the level of scientific evidence were evaluated using the Consolidated Standards of Reporting Trials and Grading of Recommendations Assessment, Development and Evaluation standards. A total of 34 articles were identified, but only eight met the eligibility criteria. The outcomes incidence of venous thromboembolism and edema were assessed in 2,022 and 1,311 passengers, respectively. The studies presented high quality evidence demonstrating prevention of edema and moderate quality evidence of reduced incidence of venous thromboembolism associated with wearing graduated compression stockings during flights.

Review
Re-expansion pulmonary edema (RPE) is a rare but potentially life-threatening complication that can occur after rapid lung expansion following the management of lung collapse. This meta-analysis aimed to investigate the risk factors for RPE following chest tube drainage in patients with spontaneous pneumothorax. We conducted a comprehensive systematic literature search in electronic databases of PubMed, ScienceDirect, Cochrane Library, and ProQuest to identify studies that explore the risk factors for RPE following chest tube drainage in spontaneous pneumothorax. Pooled odds ratios (OR) or weighted mean differences (WMD) were calculated to evaluate the risk factors. Statistical analysis was conducted using Review Manager 5.3 software. Five studies involving 1.093 spontaneous pneumothorax patients were included in this meta-analysis. The pooled analysis showed that the following risk factors were significantly associated with increased risk of RPE following chest tube drainage: the presence smoking history (OR=1.94, 95% CI: 1.22-3.10, =0.005, I2=0%), longer duration of symptoms (WMD=3.76, 95% CI: 2.07-5.45, <0.0001, I2=30%), and larger size of pneumothorax (WMD=16.76, 95% CI: 8.88-24.64, <0.0001, I2=78%). Age, sex, and location of pneumothorax had no significant association. In patients with spontaneous pneumothorax, the presence of smoking history, longer duration of symptoms, and larger size of pneumothorax increase the risk of development of RPE following chest tube drainage.

Meta-Analysis Review
RATIONALE AND OBJECTIVES
This systematic review and meta-analysis aimed to investigate the radiological predictors of post-coronavirus disease 19 (COVID-19) pulmonary fibrosis and incomplete absorption of pulmonary lesions.
MATERIALS AND METHODS
We systematically searched PubMed, EMBASE, and Web of Science for studies reporting the predictive value of radiological findings in patients with post-COVID-19 lung residuals published through November 11, 2022. The pooled odds ratios with a 95% confidence interval (CI) were assessed. The random-effects model was used due to the heterogeneity of the true effect sizes.
RESULTS
We included 11 studies. There were 1777 COVID-19-positive patients, and 1014 (57%) were male. All studies used chest computed tomography (CT) as a radiologic tool. Moreover, chest X-ray (CXR) and lung ultrasound were used in two studies, along with a CT scan. CT severity score (CTSS), Radiographic Assessment of Lung Edema score (RALE), interstitial score, lung ultrasound score (LUS), patchy opacities, abnormal CXR, pleural traction, and subpleural abnormalities were found to be predictors of post-COVID-19 sequels. CTSS and consolidations were the most common predictors among included studies. Pooled analysis revealed that pulmonary residuals in patients with initial consolidation are about four times more likely than in patients without this finding (odds ratio: 3.830; 95% CI: 1.811-8.102, I2: 4.640).
CONCLUSION
Radiological findings can predict the long-term pulmonary sequelae of COVID-19 patients. CTSS is an important predictor of lung fibrosis and COVID-19 mortality. Lung fibrosis can be diagnosed and tracked using the LUS. Changes in RALE score during hospitalization can be used as an independent predictor of mortality.

Meta-Analysis
BACKGROUND
The prevalence of pulmonary embolism (PE) in the acute exacerbation of chronic obstructive pulmonary disease (AE-COPD) is highly controversial. We conducted a systematic review and meta-analysis to summarize the epidemiology and characteristics of PE with AE-COPD for current studies.
METHODS
We searched the PubMed, EMBASE, Cochrane Library and Web of Science databases for studies published prior to October 21, 2020. Pooled proportions with 95% confidence intervals (95% CIs) were calculated using a random effects model. Odds ratios (ORs) and mean differences (MDs) with 95% confidence intervals were used as effect measures for dichotomous and continuous variables, respectively.
RESULTS
A total of 17 studies involving 3170 patients were included. The prevalence of PE and deep vein thrombosis (DVT) in AE-COPD patients was 17.2% (95% CI: 13.4%-21.3%) and 7.1% (95% CI: 3.7%-11.4%%), respectively. Dyspnea (OR = 6.77, 95% CI: 1.97-23.22), pleuritic chest pain (OR = 3.25, 95% CI: 2.06-5.12), lower limb asymmetry or edema (OR = 2.46, 95% CI:1.51-4.00), higher heart rates (MD = 20.51, 95% CI: 4.95-36.08), longer hospital stays (MD = 3.66, 95% CI: 3.01-4.31) were associated with the PE in the AE-COPD patients. Levels of D-dimer (MD = 1.51, 95% CI: 0.80-2.23), WBC counts (MD = 1.42, 95% CI: 0.14-2.70) were significantly higher and levels of PaO2 was lower (MD = -17.20, 95% CI: -33.94- -0.45, P<0.05) in the AE-COPD with PE group. The AE-COPD with PE group had increased risk of fatal outcome than the AE-COPD group (OR = 2.23, 95% CI: 1.43-3.50).
CONCLUSIONS
The prevalence of PE during AE-COPD varies considerably among the studies. AE-COPD patients with PE experienced an increased risk of death, especially among the ICU patients. Understanding the potential risk factors for PE may help clinicians identify AE-COPD patients at increased risk of PE.

Review
INTRODUCTION
Up to half of people who ascend to heights above 2500 m may develop acute mountain sickness, pulmonary oedema, or cerebral oedema, with the risk being greater at higher altitudes, and with faster rates of ascent.
METHODS AND OUTCOMES
We conducted a systematic review and aimed to answer the following clinical questions: What are the effects of interventions to prevent, and treat, acute mountain sickness? We searched: Medline, Embase, The Cochrane Library and other important databases up to January 2007 (Clinical Evidence reviews are updated periodically, please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA).
RESULTS
We found 11 systematic reviews, RCTs, or observational studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions.
CONCLUSIONS
In this systematic review we present information relating to the effectiveness and safety of the following interventions: acetazolamide, dexamethasone, gingko biloba and slow ascent.
