OBJECTIVE
Intramedullary spinal cord metastasis from lung cancer (ISCM-LC) are increasing in prevalence. We aim to investigate its clinical features, treatments and prognosis.
METHODS
We reported 6 ISCM-LC cases and conducted a systematic review. Descriptive summarization, survival analysis, and multivariate Cox regression analysis were performed to comprehensively study the disease.
RESULTS
All 6 patients had surgery. One used chemotherapy and the other had targeted drugs. Two patients died of ISCM-LC, 1 died of pulmonary embolism, 1 was alive, and 2 were lost to follow-up. We identified 197 ISCM-LC cases in literature with a mean age of 58 years and male preponderance. Small cell lung cancer accounted for 39.1%. The median interval from lung cancer to ISCM-LC was 7 months. Limb weakness was the most common symptom, and 45% cases progressed rapidly. Concomitant brain, leptomeningeal, and vertebral metastasis occurred to 55.8%, 20%, and 19.5%, respectively. Peritumoral edema appeared in 83.3%. Through survival analysis, we found sex, extraspinal metastasis, pathology, and improved symptoms affected the overall survival. Additionally, gross total resection (GTR) shared similar effectiveness with non-GTR, and other treatments following surgery hardly added extra effect. Surgery, improved symptoms, and sex were 3 independent prognostic factors after adjusting for confounding. The estimated median survival time was 5 months.
CONCLUSION
The overall survival of ISCM-LC remains poor. Surgery is an independent protective factor for survival. Surgery should be considered once tolerated, and GTR might not be necessary. In addition, female patients with improved symptoms after intervention might have better overall survival.

Meta-Analysis
BACKGROUND
HELLP syndrome, featuring hemolysis, elevated liver enzymes, and thrombocytopenia, is life-threatening disease of pregnancy that triggers comorbidities in both pregnant women and the fetus/newborn. This study provides an updated systematic review and meta-analysis of relevant studies to assess the therapeutic efficacy of corticosteroids in maternal and neonatal outcomes.
METHODS
Randomized control trials (RCTs) regarding the use of corticosteroids in the HELLP population from three electronic databases, including Ovid MEDLINE, Ovid EMBASE, andCochrane Central Register of Controlled Trials, were searched from database inception to 23 March 202323 March 2023.
RESULTS
A total of 485 patients treated with corticosteroids from 7 RCTs were included. Compared to placebo, corticosteroids therapy failed to significantly improve the maternal outcomes regard to maternal morbidity (RR = 1.36, 95%CI [0.45, 4.10]), eclampsia (RR = 1.16, 95%CI [0.76, 1.77]), acute renal failure (RR = 0.71, 95%CI [0.41, 1.22]), pulmonary edema (RR = 0.34, 95%CI [0.10, 1.15]) and oliguria (RR = 1.08, 95%CI [0.75, 1.54]). In addition, pooled data showed that it wasn't significant differences between corticosteroids therapy and placebo regarding neonatal outcomes.
CONCLUSIONS
This study compared the efficacy of corticosteroids in patients with HELLP syndrome, revealing that corticosteroids did not provide any significant benefit in clinical outcomes for pregnant women and newborns with HELLP. The conclusions of this study must be verified by a larger sample of high-quality RCTs.

Meta-Analysis
OBJECTIVES
Acute respiratory distress syndrome (ARDS) in patients with traumatic brain injury (TBI) is associated with increased mortality. Information on the prevalence of ARDS and its neurological outcome after TBI is sparse. We aimed to systematically review the prevalence, risk factors, and outcome of ARDS in TBI population.
DATA SOURCES
PubMed and four other databases (Embase, Cochrane Library, Web of Science Core Collection, and Scopus) from inception to July 6, 2020.
STUDY SELECTION
Randomized controlled trials (RCTs) and observational studies in patients older than 18 years old.
DATA EXTRACTION
Two independent reviewers extracted the data. Study quality was assessed by the Cochrane Risk of Bias tool for RCTs, the Newcastle-Ottawa Scale for cohort and case-control studies. Good neurological outcome was defined as Glasgow Outcome Scale ≥ 4. Random-effects meta-analyses were conducted to estimate pooled outcome prevalence and their 95% confidence intervals (CI).
DATA SYNTHESIS
We included 20 studies (n = 2830) with median age of 44 years (interquartile range [IQR] = 35-47, 64% male) and 79% (n = 2237) suffered severe TBI. In meta-analysis, 19% patients (95% CI = 0.13-0.27, I = 93%) had ARDS after TBI. The median time from TBI to ARDS was 3 days (IQR = 2-5). Overall survival at discharge for the TBI cohort was 70% (95% CI = 0.64-0.75; I = 85%) and good neurological outcome at any time was achieved in 31% of TBI patients (95% CI = 0.23-0.40; I = 88%). TBI cohort without ARDS had higher survival (67% vs. 57%, p = 0.01) and good neurological outcomes (34% vs. 23%, p = 0.02) compared to those with ARDS. We did not find any specific risk factors for developing ARDS.
CONCLUSION
In this meta-analysis, approximately one in five patients had ARDS shortly after TBI with the median time of 3 days. The presence of ARDS was associated with worse neurological outcome and mortality in TBI. Further research on prevention and intervention strategy of TBI-associated ARDS is warranted.

Review
BACKGROUND
WHO quoted the numbers for the Coronavirus disease 2019 (COVID-19) pandemic as of August 2021 were 200 million cases with over 4 million deaths globally. COVID-19 is associated with several respiratory pathologies. Inhaled corticosteroids (ICS) are used to improve lung function by reducing inflammation, edema, mucus secretion, and inhibiting various cytokine activities. However, there is limited data on the effect of ICS usage in patients with COVID-19. In this study, we aim to evaluate the association between the use of ICS and the outcomes in COVID-19 patients compared to standard COVID-19 treatment.
METHODS
We followed PRISMA guidelines and MOOSE protocol for conducting the systematic review and meta-analysis comparing ICS and standard COVID-19 therapy. A search on PubMed is conducted yielding 270 articles of which 6 manuscripts are finalized for inclusion in the study. Patients with COVID-19 are identified from the studies based on confirmed positive RT-PCR tests. Hospitalization, ICU admission, and mortality are selected as the outcomes of our study. Using RevMan 5.3, we performed random-effects models to estimate the pooled effect size (pooled odds ratio), 95% confidence interval (95% CI), and heterogeneity (I). Forest plots are obtained and p <0.05 is considered statistically significant.
RESULTS
Our study involves the comparison of ICS vs Non-ICS for mortality (N= 207,842 vs 166,217), ICU hospitalization (N= 1,084 vs 9,425), and the risk of hospitalization (N= 1,273 vs 1,676).Of the six studies, five reported mortality. We found a higher mortality rate in patients with asthma (60.88%, 107/160) and chronic obstructive pulmonary disease (COPD) (68.46%, 382/558) among ICS users. The overall mortality is 7.49% (107/1428). We found that ICS use was associated with higher odds of mortality (OR=1.45 95%CI: 1.10-1.91; p=0.009, I= 68%) amongst COVID-19 patients. In subgroup analysis, higher odds of mortality among COPD patients using ICS was noted [pooled OR: 1.52 (1.24-1.86); p<0.0001; I=0%]. However, no significant association between ICS and mortality was observed among asthma patients.
CONCLUSION
ICS is associated with increased mortality and risk for hospitalization in patients with COVID-19 as compared to standard non-steroid-based COVID-19 therapy. It is crucial for healthcare providers to carefully evaluate the potential risks and benefits of ICS usage in the context of COVID-19 management to optimize patient outcomes and safety.

Meta-Analysis Review
Understanding the prevalence of signs of severity identified in the Thai population with malaria could aid clinical management and disease control efforts, decrease mortality, and promote malaria elimination in Thailand. This systematic review aimed to collate the evidence regarding signs of severity identified in the Thai population with malaria. MEDLINE, Web of Science, and Scopus were searched for potentially relevant studies. The quality of the included studies was assessed using the Joanna Briggs Institute critical appraisal tools. The pooled prevalence of signs of severity among patients with severe malaria and the pooled proportion of each sign of severity among all signs of severity were estimated using random-effects models. Heterogeneity among included studies was assessed using Cochran's Q test. A subgroup analysis was performed to evaluate whether differences in pooled estimates between different study sites. Publication bias was assessed by visualizing funnel plot asymmetry and using Egger's test. Among 741 studies identified by literature searching, 12 studies of a total of 2900 patients with severe malaria, in 7 Thai hospitals, met the eligibility criteria. Results of meta-analyses showed that the signs of the severity of malaria with the highest prevalence in Thailand were jaundice (54%), hyperparasitemia (47%), impaired consciousness/coma (21%), acidosis (18%), renal impairment (13%), shock (10%), convulsions (9%), severe anemia (8%), pulmonary edema/acute respiratory distress syndrome (ARDS) (8%), hypoglycemia (4%), and bleeding/disseminated intravascular coagulation (DIC) (2%). The signs of the severity of malaria that made up the highest proportion of all signs of severity identified in the Thai population with malaria were hyperparasitemia (33%), jaundice (33%), impaired consciousness/coma (12%), acidosis (9%), renal impairment (7%), severe anemia (6%), convulsions (5%), shock (5%), pulmonary edema/ARDS (3%), bleeding/DIC (1%), and hypoglycemia (1%). The present study revealed the prevalence of signs of severity identified in the Thai population with malaria. Jaundice, hyperparasitemia, and impaired consciousness/coma were the most common signs of severity identified. These results may inform the management of patients with severe malaria and promote malaria-elimination efforts in Thailand.

PURPOSE OF REVIEW
To analyze whether the use of morphine, as initial treatment in acute cardiogenic pulmonary edema (ACPE), has an impact in clinical outcomes and mortality. A systematic review of the literature was performed, including all the studies comparing clinical outcomes in patients with ACPE who were treated or not with morphine.
RECENT FINDINGS
Seven studies were selected, none of which were a randomized trial focused on answering the aim of this systematic review. The studies consisted of clinical trial secondary analysis assessing non-invasive ventilation in ACPE, one open non-randomized trial, two propensity score evaluations from large registries, and three clinical case reviews. Most of the studies showed unfavorable results with the use of morphine in terms of adverse events and mortality, and many of them were statistically significant. Finally, the ongoing MIdazolam versus MOrphine in acute cardiogenic pulmonary edema (MIMO) trial was specifically designed to compare the results of morphine use versus midazolam. The potential hemodynamic and sedative benefit of the use of morphine for vasodilatation and dyspnea amelioration may be opposed by an increase in mortality, ICU admission, and adverse events. Until there is a randomized clinical trial, the use of morphine for ACPE should be limited.

Review
RATIONALE
Acute respiratory distress syndrome (ARDS) is currently diagnosed by the Berlin definition, which does not include a direct measure of pulmonary oedema, endothelial permeability or pulmonary inflammation. We hypothesised that biomarkers of these processes have good diagnostic accuracy for ARDS.
METHODS
Medline and Scopus were searched for original diagnostic studies using minimally invasive testing. Primary outcome was the diagnostic accuracy per test and was categorised by control group. The methodological quality was assessed with QUADAS-2 tool. Biomarkers that had an area under the receiver operating characteristic curve (AUROCC) of >0.75 and were studied with minimal bias against an unselected control group were considered to be promising.
RESULTS
Forty-four articles were included. The median AUROCC for all evaluated tests was 0.80 (25th to 75th percentile: 0.72-0.88). The type of control group influenced the diagnostic accuracy (p=0.0095). Higher risk of bias was associated with higher diagnostic accuracy (AUROCC 0.75 for low-bias, 0.77 for intermediate-bias and 0.84 for high-bias studies; p=0.0023). Club cell protein 16 and soluble receptor for advanced glycation end-products in plasma and two panels with biomarkers of oxidative stress in breath showed good diagnostic accuracy in low-bias studies that compared ARDS patients to an unselected intensive care unit (ICU) population.
CONCLUSION
This systematic review revealed only four diagnostic tests fulfilling stringent criteria for a promising biomarker in a low-bias setting. For implementation into the clinical setting, prospective studies in a general unselected ICU population with good methodological quality are needed.

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.

Prevalence and risk factors of pulmonary embolism in acute exacerbation of chronic obstructive pulmonary disease and its impact on outcomes: a systematic review and meta-analysis.
OBJECTIVE
The current study aimed to pool data for the prevalence of pulmonary embolism (PE) in acute exacerbation of chronic obstructive pulmonary disease (AE-COPD). We also aimed to assess the risk factors of PE and its impact on the outcomes of AE-COPD.
MATERIALS AND METHODS
PubMed, Embase, and CENTRAL databases were searched up to 1st January 2021 for prospective, retrospective, and cross-sectional studies reporting the prevalence of PE in AE-COPD based on computed tomography (CT) data.
RESULTS
Sixteen studies were included. Pooled data of 5035 patients indicated the prevalence of PE in AE-COPD to be 12.9% (95% CI: 8.9%-18.4%). In studies wherein, all patients underwent CT the prevalence was 19.4% (95% CI: 13.4%-27.4%). On the other hand, the prevalence of PE was 7.8% (95% CI: 3.7%-15.7%) in studies where CT was carried out only after screening patients based on study-specific diagnostic protocol. Multiple studies indicated that recent immobilization, increased D-dimer levels, lower limb edema, older age and the concomitant presence of deep vein thrombosis were independent risk factors for PE in AE-COPD. Pooled analysis indicated that PE was associated with a significantly increased risk of mortality (OR: 3.21 95% CI: 1.86, 5.54 I2=52% p<0.0001) and longer ICU/hospital stay (MD: 3.26 95% CI: 1.93, 4.58 I2=0% p<0.00001) in AE-COPD.
CONCLUSIONS
The prevalence of PE in AE-COPD is estimated to be 12.9%. This figure, however, varies based on the PE workup protocol. Higher prevalence (19.4%) was noted when all patients underwent CT as compared to when a study-specific diagnostic protocol was followed (7.8%). Recent immobilization, increased D-dimer levels, lower limb edema, older age and the concomitant presence of deep vein thrombosis are important independent risk factors for PE in patients with AE-COPD. Patients diagnosed with PE have increased mortality and longer ICU/hospital stay as compared to non-PE patients.

Review
Scorpion sting is a public health issue in several countries, particularly in America, the Middle East, India and Africa. The estimated annual global incidence of scorpion envenomings is about 1.5 million, resulting in 2600 deaths. Scorpions are Arthropoda characterized by a tail ending in a terminal bulbous (telson) containing paired venom glands and the stinger. There are 19 known families of scorpions and more than 2200 species, of which about 50 from the families of Buthidae, Hemiscorpiidae and Scorpionidae are harmful to humans. Scorpion venom is a complex structure composed of neurotoxic proteins, salts, acidic proteins and organic compounds, thereby having neurologic, cardiovascular, hematologic and renal side effects, in addition to local effects such as redness, pain, burning and swelling. When the sting is fatal, the mechanism of death is often related to cardiotoxicity with terminal pulmonary edema. However, the cholinergic excess or the neuromuscular excitation can provoke respiratory failure. Sometimes, death is due to an anaphylactic reaction to the envenoming. The purpose of this literature review is to evaluate the autopsy findings in scorpion sting-related deaths in order to better understand the pathophysiological mechanisms underlying them, thus helping pathologists in defining the correct diagnosis.
