INTRODUCTION
Heatstroke (HS) is a severe form of heat-related illness (HRI) associated with high morbidity and mortality, representing a condition that includes long-term multiorgan dysfunction and susceptibility to further heat illness.
METHODS
In a systematic review searching Medline PubMed from the studies conducted between 2009 and 2020, 16 papers were identified.
RESULTS
A hallmark symptom of heat stroke is CNS dysfunction (a hallmark sign of HS) which manifests as mental status changes, including agitation, delirium, epilepsy, or coma at the time of the collapse. Acute kidney injury (AKI), gut ischemia, blood clots in the stomach and small intestine, cytoplasmic protein clumps in the spleen, and injury of skeletal muscle (rhabdomyolysis) are all characteristics of peripheral tissue damage. Severe heat stroke tends to be complicated by rhabdomyolysis, especially in patients with exertional heat stroke. Rhabdomyolysis may lead to systemic effects, including the local occurrence of compartment syndrome, hyperkalemic cardiac arrest, and/or lethal disseminated intravascular coagulopathy. Untreated heat stroke might exacerbate psychosis, lactic acidosis, consumptive coagulopathy, hematuria, pulmonary edema, renal failure, and other metabolic abnormalities. Core body temperature and level of consciousness are the most significant indicators to diagnose the severity of heat stroke and prevent unfavorable consequences. Heatstroke is a life-threatening illness if not promptly recognized and effectively treated.
DISCUSSION
This review highlighted that core body temperature and white blood cell count are significant contributing factors affecting heat stroke outcomes. Other factors contributing to the poor outcome include old age, low GCS, and prolonged hospital stay. The prevalence of both classic and exertional heatstroke can be reduced by certain simple preventive measures, such as avoiding strenuous activity in hot environments and reducing exposure to heat stress.

Review
Quantification of pulmonary edema and congestion is important to guide diagnosis and risk stratification, and to objectively evaluate new therapies in heart failure. Herein, we review the validation, diagnostic performance, and clinical utility of noninvasive imaging modalities in this setting, including chest x-ray, lung ultrasound (LUS), computed tomography (CT), nuclear medicine imaging methods (positron emission tomography [PET], single photon emission CT), and magnetic resonance imaging (MRI). LUS is a clinically useful bedside modality, and fully quantitative methods (CT, MRI, PET) are likely to be important contributors to a more accurate and precise evaluation of new heart failure therapies and for clinical use in conjunction with cardiac imaging. There are only a limited number of studies evaluating pulmonary congestion during stress. Taken together, noninvasive imaging of pulmonary congestion provides utility for both clinical and research assessment, and continued refinement of methodologic accuracy, validation, and workflow has the potential to increase broader clinical adoption.

Meta-Analysis
OBJECTIVE
This meta-analysis was performed to evaluate the diagnostic efficacy of lung ultrasound (LUS) in cardiogenic pulmonary edema.
MATERIALS AND METHODS
An electronic search of databases, including MEDLINE, Embase, PubMed, and Web of Science, was performed to collect clinical studies on ultrasound diagnosis of cardiogenic pulmonary edema from inception to 23 March 2023. The number of patients with true-positive, true-negative, false-positive, and false-negative cardiogenic pulmonary edema diagnosed by LUS was collected, and the R package was used to analyze the diagnostic efficacy of LUS.
RESULTS
Nine pieces of literature were finally included with 2,097 participants, including 1,047 patients with cardiogenic heart failure. Across the nine included papers, the pooled sensitivity of LUS in the included studies was 0.92 (95% CI: 0.84, 0.97) with a maximum sensitivity of 0.99 (95% CI: 0.96 to 1.00) and a minimum of 0.59 (95% CI: 0.50, 0.68). The pooled specificity of the included studies was 0.87 (95% CI: 0. 82, 0.91) with a maximum specificity of 0.93 (95% CI: 0.90-0.95) and a minimum of 0.80 (95% CI: 0.67, 0.89). The pooled AUC was 0.93 (95% CI: 0.84 to 0.97), suggesting a high diagnostic value of LUS in cardiogenic pulmonary edema.
CONCLUSIONS
Lung ultrasound offers a good diagnostic efficacy for cardiogenic pulmonary edema. Further standardization of the examination method is required to provide a reference for the clinical use of LUS.

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 Review
Neurogenic pulmonary edema (NPE) is a life-threatening and severe complication in patients with spontaneous subarachnoid hemorrhage (SAH). The prevalence of NPE varies significantly across studies due to differences in case definitions, study populations, and methodologies. Therefore, a precise estimation of the prevalence and risk factors related to NPE in patients with spontaneous SAH is important for clinical decision-makers, policy providers, and researchers. We conducted a systematic search of the PubMed/Medline, Embase, Web of Science, Scopus, and Cochrane Library databases from their inception to January 2023. Thirteen studies were included in the meta-analysis, with a total of 3,429 SAH patients. The pooled global prevalence of NPE was estimated to be 13%. Out of the eight studies (n = 1095, 56%) that reported the number of in-hospital mortalities of NPE among patients with SAH, the pooled proportion of in-hospital deaths was 47%. Risk factors associated with NPE after spontaneous SAH included female gender, WFNS class, APACHE II score ≥ 20, IL-6 > 40 pg/mL, Hunt and Hess grade ≥ 3, elevated troponin I, elevated white blood cell count, and electrocardiographic abnormalities. Multiple studies showed a strong positive correlation between the WFNS class and NPE. In conclusion, NPE has a moderate prevalence but a high in-hospital mortality rate in patients with SAH. We identified multiple risk factors that can help identify high-risk groups of NPE in individuals with SAH. Early prediction of the onset of NPE is crucial for timely prevention and early intervention.

Meta-Analysis
Background To study the prevalence and types of hypertension-mediated organ damage and the prognosis of patients presenting to the emergency department (ED) with hypertensive emergencies. Methods and Results PubMed was queried from inception through November 30, 2021. Studies were included if they reported the prevalence or prognosis of hypertensive emergencies in patients presenting to the ED. Studies reporting data on hypertensive emergencies in other departments were excluded. The extracted data were arcsine transformed and pooled using a random-effects model. Fifteen studies (n=4370 patients) were included. Pooled analysis demonstrates that the prevalence of hypertensive emergencies was 0.5% (95% CI, 0.40%-0.70%) in all patients presenting to ED and 35.9% (95% CI, 26.7%-45.5%) among patients presenting in ED with hypertensive crisis. Ischemic stroke (28.1% [95% CI, 18.7%-38.6%]) was the most prevalent hypertension-mediated organ damage, followed by pulmonary edema/acute heart failure (24.1% [95% CI, 19.0%-29.7%]), hemorrhagic stroke (14.6% [95% CI, 9.9%-20.0%]), acute coronary syndrome (10.8% [95% CI, 7.3%-14.8%]), renal failure (8.0% [95% CI, 2.9%-15.5%]), subarachnoid hemorrhage (6.9% [95% CI, 3.9%-10.7%]), encephalopathy (6.1% [95% CI, 1.9%-12.4%]), and the least prevalent was aortic dissection (1.8% [95% CI, 1.1%-2.8%]). Prevalence of in-hospital mortality among patients with hypertensive emergency was 9.9% (95% CI, 1.4%-24.6%). Conclusions Our findings demonstrate a pattern of hypertension-mediated organ damage primarily affecting the brain and heart, substantial cardiovascular renal morbidity and mortality, as well as subsequent hospitalization in patients with hypertensive emergencies presenting to the ED.

Meta-Analysis
CONTEXT
For patients with acute heart failure (AHF), the methods of clinical diagnosis of pulmonary edema mainly include clinical symptoms, laboratory results, and an imaging examination. The common diagnostic methods, such as chest X-rays and computerized tomography (CT) scanning, haven't been completely satisfactory.
OBJECTIVE
The study intended to systematically, quantitatively, and comprehensively evaluate the value of a lung (pulmonary) ultrasound, performed at a patient's bedside, in the diagnosis of acute heart failure (AHF), to provide an objective basis for its clinical application and further research.
DESIGN
The research team searched PubMed, Excerpta Medica Database (EMBASE), ScienceDirect, Cochrane Library, China Journal Full-text Database (CNKI), VIP Full-text Database, Wanfang Database, and China Biomedical Literature Database (CBM) for relevant literature, from January 2010 to the present, about the use of a lung ultrasound for diagnosis of AHF patients. The team used keywords to search literature: ultrasound, AHF diagnosis, cardiogenic pulmonary edema, ultrasonic examination, AHF diagnosis, and cardiogenic pulmonary edema. The research team then conducted a meta-analysis of the collected data according to the Cochrane Handbook 5.3 with RevMan 5.3 statistical software.
SETTING
The study took place at Jinan.
OUTCOME MEASURES
The research team: (1) evaluated the quality of the included studies; (2) examined the accuracy of a lung ultrasound in the diagnosis of AHF compared to computerized tomography (CT) as well as to the conventional ultrasonic cardiogram (echocardiogram) that a cardiologist performs; (3) determined the sensitivity, specificity, and predictive value of lung ultrasound using data from two of the included studies; (4) evaluated the data by drawing funnel charts; and (5) examined the publication bias of the included studies.
RESULTS
The research team selected six controlled clinical studies, with 345 data samples, for the meta-analysis. The team performed heterogeneity tests for the included research data. For the first test, the team compared the accuracy of lung ultrasound and CT in diagnosing AHF and found obvious heterogeneity, with χ2 = 11.40, df = 3, P = .010, and I2 = 74%. Based on an analysis using a random effects model, the team found no significant differences between the two methods in the diagnosis of AHF (P = .35). For the second test, the team compared the accuracy of lung ultrasound and an ultrasonic cardiogram in diagnosing AHF and found that the data didn't differ significantly, with χ2 = 0.08, df = 1, P = .78, I2 = 0%. Based on an analysis using a fixed effects model, the team found that the accuracy of the lung ultrasound in diagnosing AHF was significantly higher than that of ultrasonic cardiogram (P = .01). In the two studies, the sensitivity and specificity were high. The majority of the funnel charts were symmetrical, but a few were asymmetrical, suggesting a publication bias, which the heterogeneity in the studies and the limited number of examined examples may explain.
CONCLUSIONS
Lung ultrasound is of great value in the diagnosis of AHF. It's highly efficient, has prospects for broad clinical application, and is worth popularizing, benefiting patients. Scholars need to verify the current study's findings in follow-up studies and in more high-quality case-control trials.
