Published: February 2021

Despite increasing utilization of continuous-flow pediatric ventricular assist devices (VAD) in children, data on exercise testing and cardiac rehabilitation (CR) are unknown. We described variation in CR practices and identified barriers to exercise testing and CR. A survey was performed through the Advanced Cardiac Therapies Improving Outcomes Network (ACTION) representing pediatric VAD centers across North America. Descriptive statistics were performed. A multidisciplinary cohort of 52 respondents from 28 pediatric VAD centers responded. Although 38% reported performing exercise testing, most (65%) used 6 minute walk tests rather than formal cycle or treadmill exercise testing. While all respondents refer to physical therapy during the initial inpatient stay for VAD placement, only 52% refer to a CR program. When performed, CR was performed at an ACTION center (84%), a local specialized center (21%), or a home-based CR program (26%). Commonly cited barriers to either CR or exercise testing were inadequate resources, inadequate implementation logistics knowledge, concerns about safety, inability of patients to travel to a CR facility, and concern about utility of exercise testing or CR. Over 90% of centers were interested in implementing a standardized pediatric VAD CR program. Utilization of exercise testing and CR after VAD placement is variable. Despite perceived barriers, most pediatric VAD centers are interested in implementing a standardized CR program for recipients. In response to this interest, we plan to implement a standardized CR protocol to all ACTION pediatric VAD centers in an effort to improve pretransplant waitlist rehabilitation and post-transplant outcomes.

Published: February 2021

Background

Contemporary optical coherence tomography (OCT) findings in patients with acute coronary syndromes (ACS) are still subject of controversy. We sought to use OCT to evaluate plaque morphology and phenotype classification in patients with ACS.

Methods

Using optical coherence tomography, culprit lesions were morphologically classified as plaque rupture, plaque erosion, calcified nodule, thin-cap fibroatheroma, thick-cap fibroatheroma (TCFA) or fibrotic, fibrocalcific or fibrolipidic plaque. Quantitative and qualitative analyses also included cholesterol crystals, neovascularization, spotty calcification and thrombus.

Results

Of the 110 lesions imaged from June 2012 to April 2016, 54 (49%) were in patients with unstable angina (UA), 31 (28%) were in non-ST-elevation myocardial infarction (STEMI) patients and 25 (23%) were in STEMI patients. Compared with STEMI patients, patients with UA/non-STEMI were older and had more hypertension, hypercholesterolemia, known coronary artery disease, prior myocardial infarction and higher use of antiplatelet therapy. More patients with STEMI had lipidic arc >90% (36.6 versus 70.8%, P = 0.003), red and mixed thrombus (12.9 versus 28.0% and 7.1 versus 44.0%, respectively, all P < 0.001), plaque rupture (29.4 versus 76.0%, P < 0.001) and TCFA (57.1 versus 84.0%; P = 0.01). Predictors of plaque rupture were STEMI at presentation (odds ratio: 9.35, 95% confidence interval: 1.66–52.61, P = 0.01) and diabetes mellitus (odds ratio: 6.16, 95% confidence interval: 1.33–28.58, P = 0.02).

Conclusions

In this single-center study, the culprit lesion of patients with STEMI had more lipid, red and mixed thrombus, plaque rupture and TCFA versus patients with UA/non-STEMI. Clinical presentation may be driven by distinct pathophysiologic mechanisms in patients with ACS.

Authors: Monello Alberto , Chiarito Mauro , Pivato Carlo Andrea , Scotti Andrea , Melillo Francesco , Munafò Andrea , Montorfano Matteo , Margonato Alberto , Colombo Antonio , Godino Cosmo
Published: February 2021

Background

Elderly constitute a high-risk subset of patients but are under-represented in clinical revascularization trials. Our aim was to investigate clinical outcomes and prognosis predictors after percutaneous coronary intervention (PCI) in this population.

Methods

Unrestricted consecutive patients with ≥75 years who underwent PCI from 2012 to 2015 were enrolled. The primary ischemic endpoint was the composite of 1-year myocardial infarction, definite/probable stent thrombosis and target vessel revascularization. The primary bleeding endpoint was defined according to the Bleeding Academic Research Consortium (BARC) classification as BARC ≥ 2.

Results

We enrolled 708 patients (mean age 80 ± 4): 14% were very elderly patients (≥85 years), 27% of patients were diabetic, 23% had chronic kidney disease (CKD), 17% atrial fibrillation and 37% presented acute coronary syndrome. The primary ischemic endpoint was reported in 67 patients (12%): 29 had myocardial infarction (5%), 25 had definite/probable stent thrombosis (4.4%) and 44 had target vessel revascularization (8%). BARC ≥ 2 bleeding was reported in 43 patients (8%). No differences were found in terms of both ischemic and bleeding events between patients with <85 and ≥85 years. Three-vessel disease and use of bare metal stent were independent predictors of the primary ischemic endpoint. Triple antithrombotic therapy and CKD were the only independent predictors of BARC ≥ 2 bleedings.

Conclusions

In our experience, elderly patients reported reassuring efficacy and safety outcomes after PCI, even if ischemic and bleeding events were frequent. Three-vessel disease and the use of bare metal stent were the only predictors of primary ischemic endpoint. Triple antithrombotic therapy and CKD were the only predictors of BARC ≥ 2 bleedings.
Gut microbiota and motoric-cognitive frailty in hospitalized older persons
Authors: Lauretani Fulvio , Longobucco Yari , Maggio Marcello
Published: February 2021

Purpose of review

In older people, many systems spontaneously change without diseases. Because of the ageing process, the gut microbiota undergoes a reduced species richness, altered balance between species, with an increased interindividual variability. The result is the reduced resilience in the presence of diseases and medications. These changes are more evident in older persons with neurodegenerative diseases and cognitive-motoric frailty.

Recent findings

A relationship between liver alteration, gut microbiota and the presence of viruses and gram-bacteria is conceivable. They determine the acceleration of neurodegenerative diseases with cognitive and motoric frailty. Hospitalization represents one of the stressors for the gut microbiota, producing dysbiosis and increasing the representation of pathobionts. The gut microbiota alterations during hospitalization may be associated with negative clinical outcomes. This phenomenon together with liver dysfunction could produce an acceleration of the trajectory of cognitive-motoric frailty towards disability and mortality. The observation that predisability is associated of both losses of cognition and motoric performance, has allowed introducing a new syndrome, the motoric-cognitive risk syndrome, which is a condition of increased risk of dementia and mobility-disability.

The interaction between liver and gut microbiota may accelerate the neurodegenerative diseases and represents a promising marker of prognostic trajectories in older patients.

Authors: Li Huaiyu , Chen Yun , Hu Ziyi , Jiang Jiawang , Li Renliang , Qiu Qianjie , Ye Jing
Published: February 2021

Background:

Gastric cancer (GC) is the most common malignant tumors in the world and surgical resection remains the primary treatment for it. Postoperative patients often suffer from gastrointestinal dysfunction as the most common side effects of surgery for GC patients. Acupuncture has a regulatory effect on gastrointestinal function. We conducted this study to assess the effectiveness of acupuncture on the restoration of gastrointestinal function of postoperative patients with GC.

Methods:

Seven electronic databases will be searched from inception to November 2020 to identify any relevant study: Medline, Embase, Cochrane Central Register of Controlled Trials (CENTRAL), China National Knowledge Infrastructure (CNKI), Wanfang Database, Chinese Biomedical Literature Database (CBM), and Chinese Scientific Journal Database (VIP database). No restriction on time and language. The primary outcome measure will be the Time to First Flatus and secondary outcome measures include the time of first defecation and the quality of life (QOL) and the number of patients with abdominal distention. We will use EndNote V.9.1 to screen the eligible literature and the I
2 statistic to assess heterogeneity in the included studies. The meta-analysis will be conducted using the Review Manager (RevMan) software (V.5.3).

Results:

Our study aims to systematically assess whether the pooled effects of currently available trials prove effects of acupuncture in improving gastrointestinal function of patients with GC in the postoperative period.

Conclusion:

This study will conduct an evaluation about the efficacy of acupuncture for the recovery of gastrointestinal function of patients with GC in the postoperative period, making up for the lack of relevant clinical evidence.

Authors: Wang Xiao , He Hongan , Zheng Jialin , Wang Jinjuan , Zheng Hao , Zhang Baoqing
Published: February 2021

Background:

In recent years, the incidence rate of children with severe Mycoplasma pneumoniae pneumonia (SMPP) is increasing, which poses a great threat to children's life and safety. There are some limitations in the existing drugs for the treatment of SMPP, and the supplementary and alternative therapy of SMPP plays an irreplaceable role in the treatment of this disease. This study will evaluate the efficacy and safety of various complementary and alternative therapies for SMPP by means of mesh meta-analysis. In order to provide the basis for clinical rational use.

Methods:

Two researchers will independently and comprehensively searched the Cochrane Central controlled trials registry, Cochrane Library, PubMed, web of science, EMBASE, CNKI, and Wanfang database to collect randomized controlled trials (RCT) studies on complementary and alternative therapies for SMPP. And the relevant references included in the systematic review/meta-analysis are screened. The retrieval time limit is from the establishment of the database to November 2020. We will use Revman 5.3 software for meta-analysis and use grade to grade the quality of evidence in the net meta-analysis (NMA).

Results:

The aim of this study was to compare the efficacy and safety of different complementary and alternative therapies in the treatment of SMPP, with a view to evaluating and ranking different interventions.

Conclusion:

The supplement and replacement therapy of SMPP can improve the clinical efficacy, relieve the clinical symptoms, improve the quality of life of children, and reduce adverse reactions, which can provide strong support for the rational use of clinicians.

Effect of Quxie capsule in patients with colorectal cancer
Authors: Zhang Suqin , Lian Peng , Huang Tao , Zhou Jianhua
Published: February 2021

Objective:

To investigate whether the Quxie capsule can decrease relapse, metastasis, and symptoms, as well as alleviate the side effects in colorectal cancer (CRC) patients.

Methods:

A comprehensive literature search of multiple databases was performed. Two reviewers independently selected trials that assessed the relapse-metastasis rate, degree of symptoms, and side effects of Quxie capsule for CRC. The meta-analysis was performed using Review Manager 5.3.

Results:

This meta-analysis included 6 studies, with a total of 408 cases. The quality of the included studies was generally low, with only 1 trial of high quality. A statistically significant difference was observed in the relapse-metastasis rate between the Quxie capsule and control groups after 2-years follow-up (n = 185, relative risk (RR) = 0.13, 95% confidence interval (CI) 0.04–0.46; P = .002). The Quxie capsule was found to reduce the traditional Chinese medicine symptom score as compared to the control (n = 208, weighted mean differences (WMD) = −4.15, 95% CI −7.30 to −1.00; P = .010), while it showed no significant improvement in the Karnofsky Performance Status score (n = 138, WMD = 5.05; 95% CI −2.95 to 13.04; P = .22). There was no difference in adverse events between the 2 groups (P = .66).

Conclusion:

This systematic review and meta-analysis showed no clear superiority of Quxie capsule for CRC patients receiving chemotherapy. The effect of Quxie capsule in CRC patients should be examined by high quality, large sample size, multi-center RCTs, with longer follow-up.
Coronary artery anomalies in tetralogy of Fallot patients evaluated by multi slice computed tomography; myocardial bridge is not a rare finding
Authors: Romeih Soha , Kaoud Alaa , Shaaban Mahmoud , Elzoghaby Mohamed , Abdelfattah Mohamed , Hashem Mohamed , Sayed Sayed , Gibreel Mohamed , Elmozy Wesam
Published: February 2021

Based on coronary angiography and interoperative inspection, anomalous origin of coronary artery crossing the right ventricular outflow tract (RVOT) is common in tetralogy of Fallot (TOF) patients. However, other coronary anomalies may be underestimated due to the overlying myocardium, epicardial fat, or adhesions due to previous palliative surgery. Currently, coronary artery visibility dramatically improved by multislice computed tomography (MSCT). We performed this study to assess the coronary arteries anatomy in TOF patients using MSCT.

All TOF patients underwent MSCT examination at our centre from 2013 till 2019 were included. Assessment of the coronary arteries’ origin and course were performed. Presence of myocardial bridge were assessed, and indexed RV mass was calculated.

318 TOF patients were included, median age 2 years (range 1 month–46 years), 175 males (55%). The abnormal coronary artery origin and course were detected in 20 patients (6%); coronary artery crossed RVOT in 13 patients (65%), 5 patients (25%) had a retro-aortic course and 2 patient (10%) had inter-arterial course. Myocardial bridges of left anterior descending artery or/and right coronary artery were reported in 100 patients (36%), no myocardial bridge of left circumflex was reported. RV mass was 29.0 ± 21.1 g/m2. There was no correlation between RV mass and presence of myocardial bridges.

MSCT is a useful imaging modality for detection of coronary arteries anomalies in TOF patients. Coronary artery crossing RVOT is not the only abnormal course and myocardial bridging is not a rare finding. Further studies are needed to demonstrate the clinical significance of these observations.
The effect of laparoscopic excisional and ablative surgery on ovarian reserve in patients with endometriomas
Authors: Chen Jianmin , Huang Dong , Zhang Jiaren , Shi Libing , Li Jing , Zhang Songying
Published: February 2021

This study investigates the effect of 2 laparoscopic methods on ovarian reserve in patients of reproductive age with endometriomas.

This was a retrospective study performed at a tertiary medical center from Jan 1st to Dec 31st, 2016. Laparoscopic cystectomy (group 1, 46 patients) and laparoscopic ovarian drainage and ablation with bipolar coagulation at low power (group 2, 30 patients) were performed to treat endometriomas larger than 3 cm. Anti-Müllerian hormone was used to assess ovarian reserve before and after surgery.

There were no statistically significant differences in patients’ baseline clinical characteristics, endometriotic stage, operative time, and follow-up time between the groups. The mean serum anti-Müllerian hormone concentration decreased significantly from 4.25 ng/ml to 3.40 ng/ml in group 1 compared with 4.47 ng/ml to 3.95 ng/ml in group 2 (P 
= .04). Pregnancy rates were 71.05% in group 1 and 73.08% in group 2, with a mean follow-up of 30.40 months and 32.35 months (P 
> .99), respectively. Although there was no statistical significance, the recurrence rate in group 1 was lower than that in group 2 (4.35% vs 16.67%, respectively; P = .11). The mean diameter of recurrent cysts was 1.75 cm in group 1 and 1.54 cm in group 2 (P = .13).

Appropriate laparoscopic electrocautery of the endometrioma wall with a bipolar instrument may be a valid alternative to traditional laparoscopic cystectomy, with less effects on ovarian reserve.
Rapid progression of high-risk proliferative diabetic retinopathy induced by insulin intensive therapy
Authors: Wang Shuya , Liu Dezheng , Zhang Xiaoyan , Bi Hongsheng
Published: February 2021

Rationale:

To summarize and analyze a case of rapid progression of high-risk proliferative diabetic retinopathy after the insulin intensive therapy (IT).

Patient concerns:

A 58-year-old type 2 diabetes female patient suffered a rapid and dramatic decline of vision acuity in the left eye in 2 months after the insulin IT. However, the best corrected visual acuity (BCVA) of her right eye, which was in much severer condition and received panretinal photocoagulation (PRP) before, improved after the IT.

Interventions:

The patient received intravitreal injection of conbercept (IVC) to her left eye, and 5 days later, underwent pars plana vitrectomy (PPV), combined with PRP and silicon oil injection.

Outcomes:

The postoperative BCVA of the left eye was 20/200 and improved to 20/160 one month later. During the subsequent 2 months of follow-up, her BCVA remained 20/160 in both eyes. Her blood glucose level also remained stable.

Lessons:

Insulin IT for untreated proliferative diabetic retinopathy (PDR) patients can cause severe and irreversible consequences, so for such patients, the conservative treatment for glycemic control may be much safer. But if insulin IT is inevitable, the patient should undergo PRP promptly before the IT, and close eye monitoring during the IT is also essential.
Allogeneic hematopoietic stem cell transplantation in a patient with HIV-negative recurrent plasmablastic lymphoma
Authors: Rong Chunmeng , Sheng Lixia , Wu An , Sun Ye , Ouyang Guifang
Published: February 2021

Introduction:

No standard guideline has been established for the treatment of plasmablastic lymphoma (PBL) and prognosis remains extremely poor, given that patients relapse early after chemotherapy and show resistance to commonly used cytostatic drugs.

Patient concerns:

We present the case of a 52-year-old HIV-negative man who presented with a mass at the left sternoclavicular joint. He had no significant comorbidities and no latent immunosuppression.

Diagnosis:

The largest lymph node measured was 36 × 19 mm. An excisional biopsy showed diffuse proliferation of large lymphoid cells which were positive for CD38 and CD138, but negative for CD20. He was diagnosed with stage IV PBL with a low IPI.

Interventions:

The patient was treated with four cycles of induction therapy with bortezomib, epirubicin and dexamethasone. He achieved complete remission. But 3 months after receiving consolidated autologous hematopoietic stem cell transplantation, he relapsed. Allogeneic hematopoietic stem cell transplantation was performed on the patient.

Outcomes:

The patient achieved remission again and there were no serious complications after allogeneic hematopoietic stem cell transplantation. This patient was followed up once every three months, and to date, he has been disease-free for more than 4 years.

Conclusion:

The survival of recurrent PBL after autologous hematopoietic stem cell transplantation is very poor. Salvage allogeneic hematopoietic stem cell transplantation may bring long-term survival opportunities for those patients. Further clinical studies are needed to explore the role of allogeneic hematopoietic stem cell transplantation in refractory and recurrent PBL.
COL5A2 as a potential clinical biomarker for gastric cancer and renal metastasis
Authors: Ding Yun-Long , Sun Shu-Fang , Zhao Guang-Liang
Published: February 2021

Background:

Gastric cancer, characterized by insidious onset and multiple metastasis, is almost incurable and has poor prognosis, and also one of the leading causes of treatment failure and death in patients with gastric cancer (GC). However, the prognosis of collagen type V alpha2 chain (COL5A2) in GC and renal metastasis is unknown.

Methods:

Recruited 148 patients who underwent GC. The diagnosis of GC was confirmed by ultrasound imaging and pathological examination. Immunohistochemistry and RT-qPCR were performed to exam the expression level of COL5A2. The statistical methods included Pearson chi-square test, Spearman-rho correlation test, univariate and multivariate cox regression analysis. Finally, this research constructed receiver operating characteristic (ROC) curves and applied the area under the curve (AUC).

Results:

Based on Pearson's chi-square test, Spearman-rho test, and univariate/multivariate cox regression, pathologic grade (P < .001), renal metastasis (P < .001) and staging (P < .001) were significantly related to COL5A2. And COL5A2 expression (hazard ratio [HR]: 18.834, P < .001) is an independent risk factor of GC. The AUC was used as the degree of confidence in judging each factor: COL5A2 (AUC = 0.878, P < .001), COL1A1 (AUC = 0.636, P = .006), COL1A2 (AUC = 0.545, P = .368), and COL3A1 (AUC = 0.617, P = .019). Through the ROC result, COL5A2 had more advantage as a biomarker for GC than other collagens.

Conclusions:

COL5A2 gene expression level might be a risk factor for GC. COL5A2 has a strong correlation with the prognosis of the disease.
Intraoperative periarticular injection can alleviate the inflammatory response and enhance joint function recovery after hip arthroplasty in elderly patients with osteoporotic femoral neck fractures
Authors: Xiong Zhizheng , Cao Shuai , Zhou Lingling , Zhang Xu , Liu Qi , Hu Jinxi , Liu Fang , Li Yongwei
Published: February 2021

Purpose:

This study aimed to investigate the potential beneficial effects of periarticular injection (PAI) of multimodal drugs on the inflammatory response and joint function after hip arthroplasty in elderly patients with osteoporotic femoral neck fractures.

Methods:

Fifty six elderly patients with unilateral osteoporotic femoral neck fractures were randomly allocated to 2 groups: the PAI group, which received the multimodal drug PAI intraoperatively before incision closure, and the control group, which received an injection of saline at the same time as placebo. The C-reactive protein (CRP), interleukin-1β (IL-1β), and IL-6 levels as well as the erythrocyte sedimentation rate (ESR) in peripheral venous blood samples were measured, along with the Visual Analogue Scale (VAS) score with activity and Harris hip score preoperation at 1, 2, 4, 7, and 14 days as well as 1 and 3 months post-operation.

Results:

The 2 groups were comparable in sex and age, and no significant differences were observed in the preoperative CRP, IL-1β, and IL-6 levels, ESR, VAS score, or Harris hip score between the 2 groups (all P > .05). However, during the postoperative period, the PAI group exhibited significantly lower levels of CRP, IL-1β, and IL-6 as well as a lower ERS and VAS score compared with the control group (P < .05), while the Harris hip score was significantly higher postoperatively in the PAI group (P < .05).

Conclusion:

Multimodal drug PAI can alleviate the inflammatory response and enhance hip function recovery after hip arthroplasty in elderly patients with osteoporotic femoral neck fractures.
Unilateral cardiogenic pulmonary edema caused by acute mitral valve prolapse
Authors: Jiang Xuandong , Cheng Xuping , Zhang Weimin
Published: February 2021

Rationale:

Unilateral cardiogenic pulmonary edema is a rare disease. A common cause is mitral valve and asymmetrical blood regurgitation that is primarily directed toward the upper right pulmonary vein, causing mean capillary pressure to increase on the right side and leading to right pulmonary edema.

Patient concerns:

A 41-year-old man was diagnosed with pneumonia after presenting with a 2-day history of cough and shortness of breath. Computed tomography indicated right pulmonary edema. He was managed with noninvasive ventilation; however, his condition continued to deteriorate, and he was transferred to the intensive care unit after tracheal intubation.

Diagnosis:

Acute posterior mitral valve prolapses; unilateral cardiogenic pulmonary edema.

Intervention:

Emergency mitral valve replacement was performed. During the operation, 2 ruptures of the chordae tendineae in the P2 scallop of the posterior mitral valve were found, and a No. 29 St. Jude mechanical mitral valve was implanted.

Outcomes:

Cardiotonic and diuretic drugs were administered postoperatively. Tracheal intubation was removed on day 7; the patient was transferred to the general ward on day 11 and discharged on day 23 postoperatively.

Lessons:

Unilateral cardiogenic pulmonary edema is easily misdiagnosed. Computed tomographic (CT) imaging presentation, brain natriuretic peptide, and cardiac color Doppler ultrasound can assist in determining a differential diagnosis. Early surgical treatment is recommended for patients with acute mitral valve prolapse.
Neonatal Kawasaki disease
Authors: Li Cancan , Du Yiming , Wang Huawei , Wu Gaohong , Zhu Xueping
Published: February 2021

Rationale:

Kawasaki Disease (KD) is a self-limiting and acute systemic vasculitis of childhood that leads to coronary artery abnormality in about 25% of untreated cases. KD is extremely rare in neonates. The purpose of this paper is to explore the clinical features and diagnosis and treatment of Neonatal Kawasaki Disease for early identification.

Patient concerns:

A 24-day-old male with 3 hours fever and a rash was admitted to our hospital.

Diagnoses:

He had a fever, rash, cracking of lips, lymph node enlargement in the neck, and distal extremity desquamation.

Interventions:

The patient was given intravenous immunoglobulin and aspirin with no complications.

Outcomes:

After discharge, the patient was followed up to 1 year old, with good prognosis and no carditis or coronary artery abnormalities.

Lessons:

Neonatal Kawasaki disease is extremely rare, and its clinical manifestation is not typical and easy to be missed. If not treated early, it will potentially give rise to coronary artery aneurysms or expansion, ischemic heart disease, and sudden death. Early diagnosis and treatment are very important.
High-grade fetal adenocarcinoma of the lung with abnormal expression of alpha-fetoprotein in a female patient
Authors: Xiao-Feng Lu , Guo-Qi Zhou , Wei Hu , Jing-Hong Li , Chao-Xia Ding , Xiao-Yan Cai , Yang Xun
Published: February 2021

Introduction:

Fetal adenocarcinoma of the lung (FLAC) is an extremely rare tumor. Due to its rarity, most of the knowledge about FLAC comes from case reports. FLAC is an invasive adenocarcinoma that is similar to the fetal lung in the pseudo-glandular stage (8–16 weeks of gestation). Owing to the differences in histopathology and clinical process, FLAC has been further divided into low-level (L-FLAC) and high-level (H-FLAC). H-FLAC is usually associated with other conventional types of lung adenocarcinoma. Lung adenocarcinoma that produces alpha-fetoprotein (AFP) is a rare type of lung cancer. Its characteristics have not been fully elucidated.

Patient's concerns:

We recently encountered this type of FLAC in a 51-year-old female patient. A computed tomography (CT) scan of the chest revealed a 74 × 51-mm sized tumor in the lingual segment of the superior lobe of the left lung. Among the tumor markers, serum AFP was elevated (816.2 ng/mL).

Primary diagnosis, interventions, and outcomes:

The diagnosis of FLAC in this patient was confirmed by bronchoscopy with lung biopsy. Through a thoracoscope, left lung pneumonectomy, and mediastinal lymph node dissection were performed. The postoperative pathological results were consistent with the preoperative diagnosis of H-FLAC. Western blotting showed the difference in the AFP expression between the normal lung tissue and the cancerous lung tissue. Eventually, the diagnosis was AFP-producing H-FLAC. Using an immunohistochemical marker for AFP, cancer cells were shown to express AFP, specifically in their nuclei. After the operation, the patient underwent conventional chemotherapy. Her serum AFP gradually decreased over the course of 2 weeks.

Conclusion:

Presently, specific tumor markers for the diagnosis of lung cancer have not been established. To the best of our knowledge, this is the first case of abnormal AFP expression in a patient with H-FLAC. It may provide a basis for the clinical diagnosis of H-FLAC, a rare tumor, and AFP may be considered as a specific tumor marker.
Neoadjuvant therapy of cetuximab combined with chemoradiotherapy in rectal cancer
Authors: Yan Qi , Zhu Jun-jing , Zhao Fang-min , Shu Qi-jin , Chen Shu-yi
Published: February 2021

Objective:

Preoperative chemoradiotherapy combined with radical resection has reduced local recurrence rates in rectal cancer. Cetuximab shows improvement in rectal cancer treatment. But the role for neoadjuvant therapy of cetuximab combined with chenmoradiotherapy in rectal cancer remains unclear. The present study aimed to use meta-analytical techniques to assess its benefit and risk.

Materials and Methods:

We searched PubMed, the Cochrane Library, Embase to identify the correlational non-comparative clinical studies and randomized controlled trials (RCTs). The primary endpoints of interest were pathological complete response (pCR), complete response (CR), partial response (PR), stable disease, progressive disease (PD), R0-resection, R1-resection, and R2-resection. The secondary included any grade of toxicity.

Results:

Eleven investigations (9 noncomparative open-label cohort studies and 2 randomized controlled trials) involving 550 patients were ultimately included. The pooled estimates of pCR was 10% (95% confidence interval [CI]: 7%–13%, I
2 = 55.9%). Simultaneously, only a small amount of patients achieved CR (11%, 95% CI: 7%–15%, I
2 = 44.0%), which was consistent with pCR. Besides, R0 resection (93%, 95% CI: 90%–96%, I
2 = 16.5%) seemed to be increased but need further exploration. The safety was also calculated, and most of the toxicities were moderate.

Conclusion:

Neoadjuvant therapy of cetuximab combined with chemoradiotherapy could not improve pCR. The raise of R0-resection rate needed to be verified by more high-quality and well-designed RCTs. Meanwhile, the morbidity of toxicity was relatively mild and acceptable.

Published: February 2021

The objective of this registry is to collect data on real-life treatment conditions for patients for whom multiple organ dialysis with Advanced Organ Support (ADVOS) albumin hemodialysis is indicated.

This registry was performed under routine conditions and without any study-specific intervention, diagnostic procedures, or assessments. Data on clinical laboratory tests, health status, liver function, vital signs, and examinations were collected (DRKS-ID: DRKS00017068). Mortality rates 28 and 90 days after the first ADVOS treatment, adverse events and ADVOS treatment parameters, including treatment abortions, were documented.

This analysis was performed 2 years after the first patient was included on January 18, 2017. As of February 20, 2019, 4 clinical sites in Germany participated and enrolled 118 patients with a median age of 60 (IQR: 45, 69) of whom 70 were male (59.3%). Patients had a median SOFA Score of 14 (IQR: 11, 16) and a predicted mortality of 80%. The median number of failing organs was 3 (IQR: 2, 4).

Four hundred twenty nine ADVOS treatments sessions were performed with a median duration of 17 hours (IQR: 6, 23). A 5.8% of the ADVOS sessions (25 of 429) were aborted due to device related errors, while 14.5% (62 of 429) were stopped for other reasons. Seventy nine adverse events were documented, 13 of them device related (all clotting, and all recovered without sequels).

A significant reduction in serum creatinine (1.5 vs 1.2 mg/dl), blood urea nitrogen (24 vs 17 mg/dl) and bilirubin (6.9 vs 6.5 mg/dl) was observed following the first ADVOS treatment session. Blood pH, bicarbonate (HCO3
-) and base excess returned to the physiological range, while partial pressure of carbon dioxide (pCO2) remained unchanged. At the time of the analysis, 28- and 90-day mortality were 60% and 65%, respectively, compared to an expected ICU-mortality rate of 80%. SOFA score was an independent predictor for outcome in a multivariable logistic regression analysis.

The reported data show a high quality and completion of all participating centers. Data interpretation must be cautious due to the small number of patients, and the nature of the registry, without a control group. However, the data presented here show an improvement of expected mortality rates. Minor clotting events similar to other dialysis therapies occurred during the treatments.
Comparative effectiveness of furosemide vs torasemide in symptomatic therapy in heart failure patients
Authors: Li Yifan , Li Li , Guo Zhipeng , Zhang Shunye
Published: February 2021

Background:

We performed this randomized controlled study protocol to investigate the efficacy and adverse effects of furosemide vs torasemide in patients with heart failure (HF).

Method:

The present study was authorized by the local research ethics committee of Shanxi Cardiovascular Hospital (no. 48736645) and informed consent was obtained from all patients. Patients were enrolled in a consecutive prospective manner on a voluntary basis. Patients who were aged 18 years and older with HF who were eligible to enroll in this randomized trial. All patients had evidence of left ventricular systolic dysfunction, confirmed by echocardiographic or nuclear imaging. The exclusion criteria were left ventricular diastolic dysfunction only, or receipt of medical or pharmaceutical care in other health systems. The primary efficacy end point was the change in procollagen type I carboxyterminal peptide (PICP) serum levels between baseline and final visit. Secondary efficacy variables included parameters related to the clinical course of HF, such as body weight, presence of edema, signs and symptoms of HF, electrocardiogram and echocardiographic evaluation, amino-terminal pro brain-type natriuretic peptide (NT-proBNP) serum levels measured by ELISA method, systolic blood pressure (SBP), diastolic blood pressure (DBP), heart rate, and renal function.

Results:

One hundred patients who met the inclusion criteria were included in our study, Table 1

showed the effects of furosemide and torsemide on measures of clinical outcomes.

Discussion:

Fluid overload is the primary cause of hospitalization among patients with HF. Preventing circulatory congestion requires careful control of dietary sodium and chronic administration of loop diuretics. Torasemide and furosemide are representatives of loop diuretics with an identical diuretic mechanism, but different pharmacokinetic properties and additional effects. There is a need for reliable conclusion regarding the comparison of furosemide and torasemide in patients with HF. Several limitation should be noted:
Comparison of airway management without neuromuscular blockers in laparoscopic gynecological surgery

New generation supraglottic airway devices are suitable for airway management in many laparoscopic surgeries. In this study, we evaluated and compared the ventilation parameters of the laryngeal mask airway-supreme (LM-S) and endotracheal tube (ETT) when a neuromuscular blocker (NMB) agent was not used during laparoscopic gynecological surgery. The second outcome was based on the evaluation of the surgical view because it may affect the surgical procedure.

This was a randomized study that enrolled 100 patients between 18 and 65 years old with an ASA I-II classification. Patients were divided into 2 groups: Group ETT and Group LM-S. Standard anesthesia and ventilation protocols were administered to patients in each group. Ventilation parameters [airway peak pressure (Ppeak), mean airway pressure (Pmean), total volume, and oropharyngeal leak pressure] were recorded before, after, and during peritoneal insufflation and before desufflation, as well as after the removal of the airway device. Perioperative surgical view quality and the adequacy of the pneumoperitoneum were also recorded.

The data of 100 patients were included in the statistical analysis. The Ppeak values in Group ETT were significantly higher in the second minute after airway device insertion. The Ppeak and Pmean values in Group ETT were significantly higher before desufflation and after removal of the airway device. No significant differences were found between the groups in terms of adequacy of the pneumoperitoneum or quality of the surgical view.

The results of this study showed that gynecological laparoscopies can be performed without using a NMB. Satisfactory conditions for ventilation and surgery can be achieved while sparing the use of muscle relaxants in both groups despite the Trendelenburg position and the pneumoperitoneum of the patients, which are typical for laparoscopic gynecological surgery. The results are of clinical significance because they show that the use of a muscle relaxant is unnecessary when supraglottic airways are used for these surgical procedures.
Platelet-rich plasma injection vs corticosteroid injection for conservative treatment of rotator cuff lesions
Authors: Wang Chenglong , Zhang Zhuo , Ma Yihang , Liu Xiangji , Zhu Qingsan
Published: February 2021

Background:

To explore the effectiveness of platelet-rich plasma (PRP) injection regarding functional recovery, pain relief, and range of motion (ROM) of shoulder compared with the corticosteroid injection in patients with rotator cuff lesions treated non-operatively.

Methods:

An electronic literature search was performed by 2 authors in the PubMed, Embase, Cochrane Library, and Web of Science databases to identify relevant randomized controlled trial (RCTs) that were published up to July 20, 2020. The quality of the included RCTs was evaluated using the approach recommended by the Cochrane Handbook for Systematic Reviews of Interventions. Standardized mean differences (SMDs) or mean differences (MDs) with 95% confidence intervals (CIs) were applied to calculate the pooled effect sizes.

Results:

Six RCTs were included in this systematic review. Meta-analysis revealed that corticosteroid injection yielded statistically significant superior functional recovery (SMD = −0.80; 95% CI, −1.42 to −0.18; P = .01) and pain relief (MD = 1.59; 95% CI, 0.30–2.89; P = .02) compared with PRP injection for rotator cuff lesions during the short-term follow-up period. However, at the medium-term and long-term follow-up, no statistically significant difference was identified between the 2 groups. Regarding the ROM of shoulder, no statistically significant difference was found between the 2 groups during the whole follow-up period.

Conclusions:

The current clinical evidence revealed short-term efficacy of corticosteroid injection and no significant medium- to long-term difference between corticosteroid and PRP injection in the treatment of rotator cuff lesions. Additional studies with longer follow-ups, larger sample sizes, and more rigorous designs are needed to draw more reliable and accurate conclusions.

Authors: Yang Ming , Li Wei Wei , Chen Jian Hua , Cui Miao Hang , Liu Jin Long
Published: February 2021

Purpose:

To discuss the value of caudate lobectomy in hilar cholangiocarcinoma (HCCA) treatment.

Methods:

A systematic review was performed in PubMed, MEDLINE database, EMBASE, and Cochrane Library for trials comparing combined caudate lobectomy with controls from January 1, 1990 to December 2, 2020. The outcomes were postoperative radical cure information, survival condition, morbidity, and mortality.

Result:

Ten studies were included. No difference was observed in the morbidity (odd ratio (OR) 0.93, 95% confidence interval (CI) 0.65–1.33) and mortality (OR 1.16, 95% CI 0.55–2.42) between the combined caudate lobectomy and control groups. Hepatectomy combined with caudate lobectomy was associated with higher incidence of radical resection (OR 3.88, 95% CI 2.18–6.90) and longer survival (hazard ratio 0.45, 95% CI 0.38–0.55).

Conclusion:

Combining caudate lobectomy can significantly increase the incidence of radical resection of HCCA and the postoperative survival time. The morbidity and mortality were not increased after the operation. Thus, caudate lobectomy should be included when performing partial hepatectomy for HCCA.

It is unclear whether antihypertensive treatment should be indicated after subarachnoid hemorrhage (SAH). Hence, we investigated the impact of blood pressure on inpatient outcomes after SAH rehabilitation.

This retrospective cross-sectional study analyzed data of SAH inpatients, as obtained from the Japan Association of Rehabilitation Database for inpatients undergoing SAH rehabilitation. Inpatients admitted to a conventional ward with a diagnosis of cerebrovascular disease were voluntarily registered in this database between January 2006 and December 2013 from hospitals in Japan. Patients were categorized into hypertensive and non-hypertensive populations and assessed using the Barthel Index (BI) and the total BI score at hospital discharge. We compared the independent population (patients with the highest score for each activity) with its non-independent counterpart. Data on the patients’ age, BI score on admission, total BI score, BI score increase, daily BI score increase, hospitalization duration, BI activities, patients’ sex, and Brunnstrom recovery stage were compared.

Eighty-eight patients with SAH were analyzed; 43 were hypertensive and 45 non-hypertensive. Hypertension was associated with increased non-independence levels (hypertensive versus non-hypertensive patients, transfers [bed to chair and back]: 15 versus 24, P = .03, odds ratio (OR) = 2.532 (95% confidence interval [CI], 1.065–6.024); toilet use: 15 versus 24, P = .03, OR = 2.532 (95% CI, 1.065–6.024); bathing: 23 versus 34, P = .0061, OR = 3.623 (95% CI, 1.414–9.259); stair climbing: 22 versus 31, P = .03, OR = 2.703 (95% CI, 1.114–6.579); and bladder control: 14 versus 24, P = .02, OR = 2.801 (95% CI, 1.170–6.711)). The total BI score of the hypertensive inpatients at discharge was lower than that of their non-hypertensive counterparts (0–75 versus 80–100, 30 versus 19, P = .03). Moreover, the BI score increase per day was significantly lower in the hypertensive group than in the non-hypertensive group (.67 versus 1.8, P = .02). The hypertensive group also had a significantly longer duration of hospitalization than the hypertensive group (52 versus 30 days, P = .02).

Hypertension was associated with longer hospitalization and poorer outcomes post-discharge, suggesting the importance of strict blood pressure control in patients who have experienced SAH.
Cardiovascular syphilis-associated acute myocardial infarction
Authors: Li Xiangdong , Wang Xue , Wang Zhiyuan , Du Beibei , Mao Cuiying , Meng Heyu , Meng Fanbo , Yang Ping
Published: February 2021

Rationale:

In recent decades, the incidence of advanced syphilis has declined due to early recognition and the application of effective antibiotics. Advanced syphilis often manifests in the cardiovascular system as simple aortitis, aortic valve insufficiency, coronary artery stenosis or obstruction, Aortic aneurysm and mucinous myocarditis. In most case reports on the subject, acute myocardial infarction caused by syphilis was reported to be due to aortic valve insufficiency and coronary stenosis as a result of the involvement of the aorta.

Patient concerns:

The patient was a 48-year-old woman. She was admitted to our hospital because of intermittent upper abdominal pain with chest tightness for 3 hours. The patient reported a past syphilis infection, when she was hospitalized for hysteromyoma surgery four years ago, and had no related treatment.

Diagnosis:

According to the characteristics of coronary angiography and results of lab tests and echocardiography, she was finally diagnosed with myocardial infarction associated with syphilis.

Interventions:

At the first diagnosis of syphilis, the patient did not received antibiotics treatment. After the diagnosis of myocardial infarction, she received the percutaneous coronary intervention (PCI) operation assisted by extracorporeal membrane oxygenation (ECMO) technology, successfully got drug -eluted stents in right coronary artery ostium and left main ostium. Then the patient received penicillin to treat the syphilis infection.

Outcomes:

After coronary revascularization, the cardiac function of the patients was gradually improved, and the left ventricular ejection fraction was gradually improved after combined with optimized drug therapy.

Lessons:

The cardiovascular system is often involved in the stages of advanced syphilis with severe complications like myocardial infarction. Standard treatment should be given as soon as syphilis is diagnosis. For stenosis of coronary ostium, the PCI assisted by ECMO technology did not only ensure the effectiveness of the treatment, but also reduce the surgical risk of the patient. This case indicated the effectiveness of ECMO-assisted PCI, and thus may provide a reference for future patient treatment.
Secondary below-knee amputation following open reduction and internal fixation of a closed pilon fracture
Authors: Wei Daiqing , Xu Yangbo , Xiang Feifan , Ye Junwu
Published: February 2021

Rationale:

Despite significant advances in surgical techniques and implants, the clinical outcome of high-energy pilon fractures remains unsatisfactory, which continues to represent numerous challenges for orthopedic trauma surgeons.

Patient concerns:

A 62-year-old man injured his right ankle after falling from a 3 m high place. There were no open wounds or other complications.

Diagnoses:

According to the X-ray and CT scans, the patient was diagnosed with pilon fracture (type AO-43-C2) and lateral malleolus fracture of the right limb.

Interventions:

The patient was initially treated with calcaneal traction upon admission to a primary hospital. Five days after the injury, the patient underwent open reduction and internal fixation (ORIF) of the fracture and vacuum sealing drainage (VSD) for wound closure.

Outcomes:

The patient presented to our hospital on the 9th day after the first ORIF operation because of critical ischemia of the affected foot and distal lower leg. Blood circulation did not improve after a series of salvage treatments, and below-knee amputation was ultimately performed.

Lessons:

This is a rare case of complete ischemic necrosis following ORIF surgery of a closed pilon fracture due to iatrogenic damage. Standardized treatment that strictly follows the guidelines, instructions, or expert consensus should be promoted in this kind of complicated pilon fracture.
