Published: February 2021

Abstract
Macular edema (ME) is an inflammatory disease characterized by increased microvascular permeability. Here, we proposed that plasma angiopoietin-like protein 2 (ANGPTL2) level may be related to the severity of ME patients with type 2 diabetes mellitus (T2DM). In this cross-sectional study, 172 T2DM patients were recruited and divided into clinically significant macular edema (CSME), non-CSME (nCSME), and control groups. Serum ANGPTL2 level was quantified by ELISA and best corrected vision acuity (BCVA) was detected. After adjust age, sex, body mass index (BMI), and duration of diabetes variables, ANGPTL2 performed statistics difference among CSME-, nCSME-groups, and control group (4.46 [3.97, 4.96, 95%CI] ng/mL in CSME group, 3.80 [3.42, 4.18, 95%CI] ng/mL in nCSME-group, 3.33 [3.03, 3.63, 95%CI] ng/mL in control, P < .01). After adjustment of confounding factors, high levels of circulating ANGPTL2 were related with the diagnosis of ME, BCVA, and C reactive protein (CRP) through univariate regression analysis (P < .05). Meanwhile, in the multiple regression model, ANGPTL2 took the mainly effect proportion for the diagnosis of diabetic macular edema (DME), with a LogWorth value 3.559 (P < .001). Our study suggested that elevated circulating ANGPTL2 may be associated with the development of DME and the severity of visual impairment in patients with type 2 diabetes.

Abstract
The mortality rate of patients diagnosed with sepsis is high. To date, many markers in sepsis patients have been studied to diagnose, determine their prognosis, and contribute to treatment. These studies were conducted in both experimental and clinical settings, but clinical trials remain limited. Therefore, more well-planned clinical studies are needed in patients with sepsis.
The current study aimed to examine the prognostic role of signal peptide-CUB-epidermal growth factor-like domain-containing protein 1 (SCUBE-1) in sepsis and sepsis-related mortality. We also wanted to study its relationship with inflammatory markers and scoring systems.
This prospective, cross-sectional, observational study included a total of 187 sepsis cases treated in the intensive care unit. Venous samples were obtained after diagnosis. The patients were separated into 2 groups: (1) the survivor group who were discharged or transferred within 28 days of the first diagnosis and (2) the nonsurvivor group who died within 28 days of the first diagnosis.
The SCUBE-1, C-reactive protein, procalcitonin, creatinine, lactate values, acute physiology and chronic health evaluation 2, sequential organ failure assessment scores were significantly higher in the survivor group, and platelets were higher in the survivor group. In addition, SCUBE-1 positively correlated with the inflammatory markers C-reactive protein, lactate, sequential organ failure assessment, and acute physiology and chronic health evaluation 2. Additionally, the SCUBE-1 value predicts 28-day mortality, and the optimal cutoff value for predicting mortality is 4,73 pg/mL.
Sepsis is a disease with high mortality. SCUBE-1 can be used as a new prognostic factor for sepsis patients.
Evaluation of pediatric procedural sedation education in pediatric emergency medicine fellowships
Authors: Sulton Carmen D. , Burger Rebecca K. , Figueroa Janet , Taylor Taryn R. 
Published: February 2021

Abstract
Pediatric procedural sedation (PPS) is often performed outside of the operating room, and by various sub-specialty providers. There is no consistency in how pediatric emergency medicine (PEM) fellows are trained in PPS. The objective of this study was to survey PEM program directors (PDs) and PEM fellows about their current sedation teaching practices via a direct survey. While many fellowship programs train PEM fellows in PPS, we hypothesize that there is no consistent method of developing and measuring this skill.
A 12-question survey was sent to PEM PDs directly via email. A separate 17-question survey was sent to current PEM fellows via their program coordinators by email. Each survey had multiple choice, yes-no and select-all program questions. Responses were collected in an online (REDCap) database and summarized as frequencies and percentages.
Based on identifiable email, 67 programs were contacted, with a PD response rate of 46 (59%). Sixty-two program coordinators were contacted based on identifiable email with 78 fellow responses. We noted that 11/46 PD respondents offer a formal PPS rotation. Thirty programs report using propofol in the emergency department and 93% of PD respondents (28/30) actively train fellows in the use of propofol. Approximately 62% of PEM fellow respondents (48/78) report sedating without any attending oversight. Twenty-eight percent of PEM fellow respondents report using simulation as a component of their sedation training.
PPS is a critical skill. However, there is a lack of consistency in both education and evaluation of competency in this area. An organized PPS rotation would improve PPS case exposure and PPS skills.
Pulmonary artery intimal sarcoma mimicking pulmonary thromboembolism
Authors: Li Ying-Chun , Li Le-Yao , Tong Hai-Chao , Xu Hong-Tao , Ma Shuang , Yang Lian-He , Zhang Wan-Lin , Sotolongo Gina , Wang Endi 
Published: February 2021

Abstract

Rationale:
Pulmonary artery intimal sarcoma is a rare tumor with exceptionally high mortality and easily misdiagnosed as pulmonary thromboembolism pulmonary thromboembolism (PTE) due to the nonspecific clinical presentation and symptom. Misdiagnosis or untimely diagnosis makes the disease progress to an advanced stage and eventually leads to a poor prognosis.

Patient concerns:
A 37-year-old Chinese female presented with chest tightness and dyspnea for 3 months. Echocardiography and chest computed tomography revealed an intraluminal obstruction of the pulmonary arteries. Tests of serum tumor makers showed slight elevation for carbohydrate antigen-125, and α-fetoprotein. PTE was suspected according to the radiological and laboratory findings.

Diagnosis:
Microscopic findings of the presumed thrombus showed prominent myxoid and edematous background with atypical spindled cells and curvilinear vascularity. Immunohistochemical staining demonstrated that the atypical spindled cells were positive for vimentin but negative for CK, S100, SMA, desmin, CD68, STAT6, CD34, β-catenin, ALK-p80, p53, and MDM2. According to the radiological and pathological findings, the diagnosis of fibrosarcoma of pulmonary artery was made.

Interventions:
The patient underwent surgical resection and the mass was excised as completely as possible.

Outcome:
Follow-up information showed no evidence of recurrence or metastasis after 3 months postresection.

Lessons:
Because of the low incidence rate, nonspecific clinical symptoms, and radiological findings, primary fibrosarcoma of the pulmonary artery is commonly misdiagnosed as PTE. Pathological examination is necessary to confirm the diagnosis.
Foramen magnum meningioma with excessive calcification and no dura tail sign
Authors: Li Li , Lan Zhigang , Richard Seidu A. , Zhang Yuekang 
Published: February 2021

Abstract

Rationale:
Foramen magnum meningiomas are very rare lesions. They frequently originate from the arachnoid cells at the dura matter of the craniocervical junction. Foramen magnum meningiomas are challenging for neurosurgeons because of the complex anatomy of foramen magnum. We present a rare case of FMM with excessive calcification and without the dura tail sign which made the lesion mimic a teratoma.

Patients concerns:
A 63 years old woman presented with progressive numbness and hyperesthesia of the shoulders and upper limbs for 2 and half years. She also experienced occasional headaches and dizziness with no nausea, vomiting or fever.

Diagnoses:
Computed tomography scan, and magnetic resonance imaging revealed a calcified mass at occipital cistern. The lesion did not show the usual “dura tail sign” which made it mimic a teratoma on magnetic resonance imaging. Histopathology established meningioma.

Intervention:
The tumor was completely resected via suboccipital approach.

Outcomes:
Two years follow-up revealed no recurrence of the lesion and no neurological deficits.

Lessons:
We advocate the use of electromyographic and auditory brainstem responses to monitor the inferior cranial nerves because the tumor often adheres to these nerves.
Acute external iliac artery thrombosis following pelvic fractures
Authors: Zhang Shuliang , Sheng Hongfeng , Xu Bin , Lao Yangjun 
Published: February 2021

Abstract

Rationale:
Pelvic fractures associated with acute external iliac artery thrombosis is less common, it is easily ignored in clinical practice, and it can result in limb amputation and hemipelvectomy due to prolonged limb ischemia. We present 2 patients with acute external iliac artery thrombosis following pelvic fractures.

Patient concerns:
Case 1 is a 49-year-old male with occlusion of the right external iliac artery and pelvic fractures. Case 2 is a 52-year-old male with left external iliac artery occlusion and bilateral internal iliac artery rupture following pelvic fractures.

Diagnoses:
Case 1 was diagnosed with computed tomography angiography. Case 2 was diagnosed with ultrasound examination and computed tomography angiography.

Interventions:
Case 1 was performed an open incision to remove thrombus of the right external iliac artery, the right iliac-femoral artery artificial bypass was adopted to restore the blood flow. Case 2 underwent segmental resection of the damaged artery and artificial vascular implantation of left external iliac artery, and angiographic embolization of bilateral internal iliac artery. However, a left hip disarticulation was performed due to osteofascial compartment syndrome at last.

Outcomes:
Case 1 was cured and discharged smoothly. Case 2 survived but left with a disability after disarticulation.

Lessons:
Acute external iliac artery thrombosis after pelvic fractures is rare and limb-threatening, life-threatening. It is very important to detect and treat this potential complication timely when a patient with a pelvic fracture.
Accuracy of gamma-glutamyl transpeptidase-to-platelet ratio (GPR), red cell distribution width (RDW), aspartate aminotransferase-to-platelet ratio index (APRI), and the fibrosis-4 index (FIB4) compared with liver biopsy in patients with drug-induced liver injury (DILI)

Abstract
This study objected to evaluate the accuracy of the gamma-glutamyl transpeptidase-to-platelet ratio (GPR), aspartate aminotransferase-to-platelet ratio index (APRI), red cell distribution width (RDW), and fibrosis-4 index (FIB4) index, compared with liver biopsy (LB), in predicting the severity of inflammation in drug-induced liver injury (DILI) patients.
We evaluated patients with DILI who were followed at the First Hospital of Jilin University and underwent LB. Accuracy of each method was analyzed using ROC analysis. Classifications of liver inflammation included G0–4.
One hundred fifty six DILI patients were included with LB and complete medical records. 62.8% (98), 39.1% (61), and 16.7% (26) were classified as ≥G2, ≥G3, or G4, respectively. The AUROCs, by degree of inflammation, were: ≥G2: GPR: 0.654, RDW: 0.635, APRI: 0.728, and FIB4: 0.739; ≥G3: GPR: 0.623, RDW: 0.703, APRI: 0.777, and FIB4: 0.781; and G4: GPR: 0.556, RDW: 0.647, APRI: 0.729, and FIB4: 0.714. To predict ≥G2 inflammation, there were no differences between the AUROCs for GPR, RDW, APRI, and FIB4. To predict ≥G3 inflammation, the AUROCs for FIB4 and APRI were higher than that for GPR (0.781 vs 0.623, P < .01; 0.777 vs 0.623, P < .05). As for G4 inflammation, the AUROCs for FIB4 and APRI were also higher than GPR (0.714 vs 0.556, P < .05, 0.729 vs 0.556, P < .05).
When the level of inflammation was higher than G2 in patients with DILI, it could be predicted using APRI and FIB4 as non-invasive markers for this condition.

Abstract
Studies comparing long-term clinical outcomes of statin treatment between acute myocardial infarction (AMI) patients with prediabetes and those with type 2 diabetes mellitus (T2DM) after successful percutaneous coronary intervention (PCI) with the newer-generation drug-eluting stents (DESs) are limited. We compared 2-year clinical outcomes between these patients.
A total of 11,962 AMI patients were classified as statin users (n = 10,243) and statin nonusers (n = 1719). Thereafter, statin users and nonusers were further divided into the normoglycemia, prediabetes, and T2DM groups. The major outcome was the occurrence of major adverse cardiac event (MACE) defined as all-cause death, recurrent myocardial infarction (Re-MI), or any repeat coronary revascularization.
After statin treatment, the cumulative incidences of MACE (P = .314), all-cause death, cardiac death (CD), Re-MI, and any repeat revascularization were similar between the prediabetes and T2DM groups. However, the cumulative incidences of MACE (P = .025) and all-cause death (P = .038) in the prediabetes group and those of MACE (P = .001), all-cause death (P = .009), and CD (P = .048) in the T2DM group were significantly higher than those in the normoglycemia group. Moreover, in all the 3 glycemic groups, the cumulative incidences of MACE, all-cause death, and CD were significantly higher among statin nonusers than among statin users.
This study revealed that AMI patients with prediabetes had worse clinical outcomes than those with normoglycemia and comparable to those with T2DM after 2-year statin treatment. However, further studies are warranted to confirm the current findings.

Abstract
Coronavirus disease 2019 (COVID-19) has rapidly spread across China and many countries worldwide, and community healthcare workers at the front lines of disease control are under high physical and mental pressure. This study investigated the mental health status of community healthcare workers during the COVID-19 outbreak in Sichuan Province, China. This cross-sectional study, which was conducted from February 8 to 18, 2020, involved 450 healthcare workers in 18 community hospitals who had worked for more than 1 year. A self-designed demographic data questionnaire and Symptom Checklist 90 (SCL-90) were provided to the participants through links and quick response codes. The respondents completed and submitted the questionnaires online. Binary logistic regression was used to analyze multiple factors related to the SCL-90 scores of these community healthcare workers in China. For the 450 community healthcare workers who completed the study, the median scores in each SCL-90 factor were lower than the Chinese norms, and 119 (26.4%) participants were SCL-90 positive. Among them, 178 participants were doctors and had the highest scores on most SCL-90 factors except for obsessive compulsiveness, hostility, phobic anxiety, and psychoticism (P < 0.05). The top 3 positive items for doctors working in the community were obsessive compulsiveness, others, and somatization, and those among nurses were obsessive compulsiveness, others, and hostility. Sex, type of workers, and occupational exposure risk to COVID-19 were independent risk factors for the mental health status of the community healthcare workers. Overall, the community healthcare workers experienced psychological problems during the COVID-19 outbreak in Sichuan Province, China. More attention should be paid to the mental health of these workers, and their mental status should be regularly assessed. Psychological interventions should be provided to those with serious mental problems through networks or telephone visits.
Correlation between semiquantitative and volumetric 18F-FDG PET/computed tomography parameters and Ki-67 expression in breast cancer
Authors: Mohamadien Nsreen R. A. , Sayed Mohamed H. M. 
Published: February 2021

Objectives
To evaluate the relationship between semiquantitative and volumetric parameters on 18F-FDG PET/computed tomography (CT), including maximum standardized uptake value (SUVmax), mean standardized uptake value (SUVmean), metabolic tumor volume (MTV), total lesion glycolysis (TLG), tumor to liver ratio (TLR) and tumor to mediastinum ratio (TMR) with the level of Ki-67 expression in breast cancer.

Patient and methods
We retrospectively reviewed 105 female patients with newly diagnosed breast cancer who underwent baseline 18F-FDG PET/CT and had immunohistochemical staining to determine the level of Ki-67 expression. The following PET parameters were measured (SUVmax, SUVmean, MTV, TLG, TLR and TMR) and correlated with level of Ki-67 expression.

Results
Significant moderate positive correlations were found between the PET parameters (primary SUVmax, SUVmean, TLG, TLR and TMR) and level of Ki-67 expression. The primary SUVmax had the highest correlation coefficient (r = 0.461) followed by TMR (r = 0.455) and P value of <0.001 for both. In ROC analysis, primary SUVmax had the largest area under the curve (0.806, P = 0.0001), with sensitivity of 76.5 % and specificity of 75% for prediction of high Ki-67 level. In univariate analysis, all PET parameters, patient age, tumor grade, molecular subtype, estrogen receptor and progesterone receptor status were significantly associated with Ki-67 level. In multivariate regression analysis, only tumor grade [odds ratio (OR) = 20.460, 95% confidence interval (CI): 11.360–29.559, P = <0.0001], molecular subtype (OR = −21.894, 95% CI: −37.921 to −5.866, P = 0.008), SUVmax (OR = 2.299, 95% CI: 0.703–3.895, P = 0.005) and TLR (OR = −4.908, 95% CI: −9.476 to −0.340, P = 0.035) were found to be the strongest independent predictor factors for the level of Ki-67 expression and hence proliferative activity of malignant cells in breast cancer.

Conclusion
The semiquantitative parameters and volumetric 18F-FDG PET/CT parameter, that is, TLG correlated well with proliferation marker Ki-67 in breast cancer. 18F-FDG PET/CT imaging can be used as a useful noninvasive diagnostic tool in imaging cellular proliferation and hence may substitute for in vitro testing of molecular markers in the diagnoses and staging of breast cancer.

Published: February 2021

Objectives
The relationship between eosinophils and cancer prognosis is unknown. Therefore, we analyzed the relationship between circulating eosinophils and the survival of stage IIA and IIB pancreatic cancer patients who underwent surgical resection.

Methods
This study included a retrospective cohort of 67 consecutive patients. Patients were categorized into two different groups based on the optimal cutoff for pretreatment levels of each biomarker, according to the receiver operating characteristic curves.

Results
The Kaplan-Meier method showed that low eosinophil (P = 0.0403), high neutrophil (P = 0.0066), and high monocyte (P = 0.0003) counts were associated with short overall survival (OS). Low lymphocyte-to-monocyte ratio (P = 0.0194) and eosinophil-to-lymphocyte ratio (ELR) (P = 0.0413) were associated with reduced OS. In multivariate analysis, histological differentiation (P = 0.0014), high neutrophils (P = 0.047), high monocytes (P = 0.029), and low eosinophils (P < 0.0001) were correlated with poorer OS. Histological differentiation (P = 0.033), low lymphocyte-to-monocyte ratio (P = 0.029), and low ELR (P = 0.005) were correlated with poor OS and were significant independent prognostic factors of poor outcomes.

Conclusions
Low eosinophils and low ELR were significant independent prognostic factors of poor outcomes.
Effect of Pancrelipase Therapy on Exocrine Pancreatic Insufficiency Symptoms and Coefficient of Fat Absorption Associated With Chronic Pancreatitis
Authors: Barkin Jodie A. , Barkin Jamie S. 
Published: February 2021

Objective
The aim of this study was to evaluate whether improvement in coefficient of fat absorption (CFA) with pancreatic enzyme replacement therapy correlates with clinical symptoms in patients with chronic pancreatitis with moderate to severe exocrine pancreatic insufficiency.

Methods
Data were pooled from 2 randomized double-blind trials of the effects of 1 week of pancrelipase (n = 59) versus placebo (n = 57) on CFA and stool frequency, stool consistency, abdominal pain, and flatulence; 1 trial included a 51-week open-label pancrelipase treatment period (n = 34).

Results
Compared with placebo, significantly more patients receiving pancrelipase reported decreased stool frequency at week 1 (72% vs 38%; P < 0.001). Although 30% of patients receiving pancrelipase and 20% receiving placebo reported improved stool consistency, changes in stool consistency, abdominal pain, and flatulence were not different between groups. Mean CFA absolute change from baseline was significantly greater with pancrelipase versus placebo (24.7% vs 6.4%; P < 0.001). Improvements in stool consistency and frequency correlated with CFA improvement. Symptom improvements persisted or further improved through 52 weeks of treatment.

Conclusions
Pancrelipase significantly improved exocrine pancreatic insufficiency maldigestive symptoms. Improvements in objective stool symptoms with pancreatic enzyme replacement therapy correlated with CFA improvement at 1 week.

Authors: Imam Zaid , Hanna Angy , Jomaa Diana , Khasawneh Majd , Abonofal Abdulrahman , Murad M. Hassan 
Published: February 2021

Objectives
Hypercalcemia of malignancy confers a poor prognosis. This systematic review evaluated published cases of hypercalcemia of malignancy presenting with acute pancreatitis (AP), in terms of clinical presentation and outcomes.

Methods
A comprehensive review of PubMed and Embase until March 18, 2020, was conducted. Studies were included if they reported on patients with hypercalcemia of malignancy and AP with attempts to exclude other etiologies of hypercalcemia and AP. Two independent reviewers selected and appraised studies using the Murad tool.

Results
Thirty-seven cases were identified. Mean (standard deviation) age was 44.8 (2.46) years. Mean (standard deviation) presenting corrected calcium was 14.5 (0.46) mg/dL. Parathyroid carcinoma (21.6%) and multiple myeloma (21.6%) were the most common malignancies. Cases were classified as severe (37.8%), mild (21.6%), and moderately severe (18.9%), whereas 21.6% did not report severity. Necrotizing pancreatitis developed in 21.6% of cases. Most cases were treated with intravenous hydration and bisphosphonates or calcitonin/calcitonin analogues. Mortality was 32.4% during the same presentation of AP. Among mortality cases, 10 of 12 had severe AP, and 5 of 12 had necrotizing pancreatitis. Degree of hypercalcemia did not influence mortality.

Conclusion
Acute pancreatitis associated with hypercalcemia of malignancy is rare. One in 3 patients with this presentation may not survive AP.
