Authors: Li Xing-Xing , Fan Zong-Jing , Cui Jie , Lin Quan , Zhuang Rui , Liu Rong-Peng , Wu Yang 
Published: April 2021

Abstract

Background:
Percutaneous coronary intervention (PCI) is an effective revascularization strategy in patients with coronary heart disease (CHD). However, recent studies had indicated that postPCI patients usually suffer from a low-quality life. Cardiac rehabilitation (CR) has been recommended by numerous guidelines in the clinic for these patients. And Baduanjin exercise can significantly benefit patients with CHD. Regrettably, the effect of Baduanjin exercise on postPCI patients is still not clear. Therefore, this systematic review and meta-analysis protocol is planned to explore the effect of Baduanjin exercise in patients with CHD who have undergone PCI.

Methods:
PubMed, Excerpta Medica Database, Cochrane Library, Web of Science, Wanfang Database, SINOMED, China Science and Technology Journal Database, and China National Knowledge Infrastructure will be searched for appropriate articles from respective inceptions until December 1th, 2020. Two reviewers will independently conduct article selection, data collection, and risk of bias evaluation. Disagreements will be resolved first by discussion and then by consulting a third author for arbitration. The primary outcome will include left ventricular ejection fraction. And the change in the scores on the Seattle Angina Questionnaire, SF-36 health survey scale, Zung Self-rating Anxiety scale and self-rating depression scale will be used as the secondary outcomes. RevMan 5.3 will be used for meta-analysis.

Results:
This systematic review and meta-analysis will explore whether Baduanjin exercise is an effective intervention in postPCI patients.

Conclusion:
This systematic review and meta-analysis will provide convincing evidence of Baduanjin exercise that specifically focuses on CR of Baduanjin exercise on CHD after PCI.

A case report on death from acute bacterial cholangitis accompanied by von Meyenburg complexes
Authors: Watanabe Noriko , Ohno Shin-ichiro , Sakuma Moe , Kuriwaki Mayo , Miura Mai , Kuroda Masahiko 
Published: April 2021

Abstract

Rationale:
In some cases, autopsy is the first opportunity to find a previously unrecognized critical infection. Pathogens are identified by various methods, such as microscopic examination, special stains, culture tests, and immunohistochemistry. Here, we report a case of 16S ribosomal RNA (rRNA) gene sequencing using a postmortem formalin-fixed, paraffin-embedded (FFPE) tissue, which was useful for identifying pathogenic microbes.

Patient concerns:
Autopsy was performed on an 87-year-old man who had chronic renal failure and had developed sepsis from a central venous catheter infection 10 days before his death. Prior to these events, von Meyenburg complexes (VMCs) were also found during regular checkups.

Diagnosis:
Postmortem microscopic examination revealed acute purulent cholangitis with numerous microabscesses, accompanied by VMCs. Gram-negative rods were observed in some microabscesses, which were considered causative pathogens.

Interventions:
16S rRNA gene sequencing using postmortem FFPE tissue

Outcomes:

Pseudomonas aeruginosa was identified, different from the one detected in the central venous catheter culture while alive.

Lessons:
16S rRNA gene sequencing is a useful tool for identifying pathogenic microbes in postmortem FFPE tissues. This technique may be useful for amplicon sizes of approximately 100 bp or less.
Dual therapy with an oral non-vitamin K antagonist and a P2Y12 inhibitor vs triple therapy with aspirin, a P2Y12 inhibitor and a vitamin K antagonist for the treatment of diabetes mellitus patients with co-existing atrial fibrillation following percutaneous coronary intervention
Authors: Wang Qiang , Yang Keping 
Published: April 2021

Abstract

Background:
In this analysis, we aimed to compare the efficacy and safety of dual therapy (DT) with a non-vitamin K oral anticoagulant (NOAC) and an adenosine diphosphate receptor antagonist (P2Y12 inhibitor) vs triple therapy (TT) with aspirin, a P2Y12 inhibitor and a vitamin K antagonist for the treatment of diabetes mellitus (DM) patients with co-existing atrial fibrillation (AF) following percutaneous coronary intervention (PCI).

Methods:
Medical Literature Analysis and Retrieval System Online (MEDLINE), http://www.ClinicalTrials.gov, Excerpta Medical data BASE (EMBASE), Web of Science, Cochrane Central and Google Scholar were the searched databases. Studies that were randomized trials or observational studies comparing DT vs TT for the treatment of DM patients with co-existing AF following PCI were included in this analysis. The adverse cardiovascular outcomes and bleeding events were the endpoints. This meta-analysis was carried out by the RevMan version 5.4 software. Risk ratios (RR) with 95% confidence intervals (CI) were used to represent data and interpret the analysis.

Results:
A total number of 4970 participants were included whereby 2456 participants were assigned to the DT group and 2514 participants were assigned to the TT group. The enrollment period varied from year 2006 to year 2018. Our current results showed that major adverse cardiac events (RR: 1.00, 95% CI: 0.84–1.20; P = .98), mortality (RR: 1.08, 95% CI: 0.78–1.48; P = .66), myocardial infarction (RR: 1.02, 95% CI: 0.74–1.42; P = .90), stroke (RR: 0.94, 95% CI: 0.53–1.67; P = .84) and stent thrombosis (RR: 1.09, 95% CI: 0.56–2.10; P = .80) were similar with DT versus TT in these patients. However, the risks for total major bleeding (RR: 0.66, 95% CI: 0.54–0.82; P = .0001), total minor bleeding (RR: 0.74, 95% CI: 0.64–0.85; P = .0001), Thrombolysis in Myocardial Infarction (TIMI) defined major bleeding (RR: 0.58, 95% CI: 0.35–0.95; P = .03), TIMI defined minor bleeding (RR: 0.62, 95% CI: 0.42–0.92; P = .02), intra-cranial bleeding (RR: 0.34, 95% CI: 0.13–0.95; P = .04) and major bleeding defined by the International Society on Thrombosis and Hemostasis (RR: 0.68, 95% CI: 0.51–0.90; P = .008) were significantly higher with TT.

Conclusions:
DT with a NOAC and a P2Y12 inhibitor was associated with significantly less bleeding events without increasing the adverse cardiovascular outcomes when compared to TT with aspirin, a P2Y12 inhibitor and a Vitamin K antagonist for the treatment of DM patients with co-existing AF following PCI. Hence, DT is comparable in efficacy, but safer compared to TT. This interesting hypothesis will have to be confirmed in future studies.

Published: April 2021

Abstract
Several studies have reported an association between the rapidity of reduction in peripheral blood blast count or recovery of normal hematopoiesis and treatment outcome during therapy in children with acute lymphoblastic leukemia (ALL). However, little is known about the impact of both of these aspects on prognosis in pediatric ALL. Accordingly, the purpose of this study was to evaluate whether the combined use of blood blast count and platelet count could predict event-free survival (EFS) and overall survival (OS) when minimal residual disease (MRD) detection was not available.
A total of 419 patients aged 0 to 14 years diagnosed and treated for ALL between 2011 and 2015 were enrolled.
Patients with a blast count ≥0.1 × 109/L on day 8 exhibited significantly lower survival rates than that in those with blast counts <0.1 × 109/L. The EFS and OS in patients with platelet count ≥100 × 109/L on day 33 were significantly higher than those with platelet counts <100 × 109/L. In univariate and multivariate analyses, patients with low blast count on day 8 and high platelet count on day 33 were significantly associated with better EFS and OS. The combination of blast cell count on day 8 and platelet count on day 33 demonstrated a strong association with MRD-based risk stratification.
Complete blood count is an inexpensive, easy to perform, and reliable measurement in children with ALL. The combination of blast count and platelet count during and after induction chemotherapy was a significant and independent prognostic factor for treatment outcome in pediatric ALL.

Published: April 2021

Abstract

Background:
The aim of the study was to evaluate the efficacy of nicorandil and alprostadil on myocardial protection in patients undergoing elective percutaneous coronary intervention (PCI).

Methods:
In this prospective, single-blinded, randomized controlled study, 90 consecutive patients scheduled for elective PCI for de novo coronary lesions were assigned to the nicorandil, alprostadil, and nitroglycerin groups in a 1:1:1 ratio. Drugs were administered intracoronary via a targeted perfusion microcatheter. The primary endpoint was the thrombolysis in myocardial infarction (TIMI) myocardial perfusion frame count (TMPFC). Additionally, the corrected TIMI frame count (cTFC), TIMI myocardial perfusion grade (TMPG), and incidence of periprocedural myocardial injury (PMI) were assessed.

Results:
Both nicorandil and alprostadil were significantly effective in reducing TMPFC (114.6 ± 33.7 vs 93.4 ± 30.9, P = .016; 114.3 ± 34.3 vs 94.7 ± 33.3, P = .029, respectively). Similar findings were observed in the improvement of cTFC (20.3 ± 10.5 vs 13.5 ± 5.0, P = .003; 20.2 ± 7.4 vs 15.2 ± 5.2, P = .003, respectively) and percentage of TMPG 3 (100% vs 82.8%, P = .052; 83.3% vs 96.7%, P = .196, respectively); whereas, nitroglycerin produced a limited effect on TMPFC (114.4 ± 30.9 vs 112.1 ± 31.9, P = .739), cTFC (19.4 ± 7.2 vs 19.3 ± 7.2, P = .936), and percentage of TMPG 3 (86.7% vs 86.7%, P = 1.000). No significant difference was found in the incidence of PMI (16.7% vs 16.0% vs 27.6%, P = .537), though it was comparatively lower in the nicorandil and alprostadil groups. Furthermore, the intracoronary administration of nicorandil and alprostadil had a mild effect on blood pressure and heart rate.

Conclusions:
The intracoronary administration of nicorandil and alprostadil via a targeted perfusion microcatheter was more effective in improving myocardial perfusion in patients undergoing elective PCI than nitroglycerin.
Extremely delayed solitary cerebral metastasis in patient with T1N0M0 renal cell carcinoma after radical nephrectomy
Authors: Choo Yoon-Hee , Seo Youngbeom , Choi Joonhyuk 
Published: April 2021

Abstract

Rationale:
Although renal cell carcinoma (RCC) is one of the common origins of brain metastasis, few cases of extremely delayed brain metastasis from RCC, more than 10 years after nephrectomy, have been reported. We present a rare case of extremely delayed brain metastasis from RCC, also performed a literature review to increase knowledge of the characteristics for extremely delayed brain metastasis from RCC.

Patient concerns:
A 72-year-old man presented with right-sided hemiplegia and dysarthria. The patient had a history of radical nephrectomy for RCC with stage T1N0M0 15 years earlier.

Diagnosis:
Magnetic resonance imaging with contrast revealed a 2-cm sized non-homogenous enhanced mass in the left frontal lobe with peritumoral edema. The pathological examination after surgery reported metastatic clear cell RCC.

Interventions:
A craniotomy for removal of the mass was performed at the time of diagnosis. Stereotactic radiosurgery was performed for the tumor bed 3 weeks after craniotomy, and then, chemotherapy was started 2 months after the SRS.

Outcomes:
Metastasis progressed to multiple organs 6 months after the craniotomy. The patient chose a hospice and no longer visited the hospital.

Lessons:
In cases with a history of nephrectomy for RCC, long period follow-up is necessary for monitoring RCC brain metastasis and pathologic diagnosis should be confirmed.

Published: April 2021

Background
Nodular lymphocyte-predominant Hodgkin lymphoma (NLPHL) is an uncommon subtype of Hodgkin lymphoma. Data are limited regarding 18F-labelled fluoro-2-deoxyglucose (FDG)-PET use in NLPHL. We are reporting our experience with FDG-PET utility in staging and response assessment NLPHL patients.

Methods
We retrospectively studied a population of all newly diagnosed or relapsed/refractory patients who underwent both pre-treatment contrast-enhanced computed tomography (CeCT) and an FDG-PET and also at the end of planned treatment.

Results
We identified 68 patients found to have in total 312 scans, 78 paired pre-therapeutic and post-treatment CeCT and FDG-PET scans. Among them, 55 were male, with a median follow-up was 48 months. Median SUV-max was 8.3 (2.0–21.0). FDG-PET and CeCT were concordant in 80% (62/78) of staging scans. In 20% (16/78) of patients in whom a discordance was observed, FDG-PET resulted in upstaging in 13 scans and downstaging in 3 scans. The sensitivity of CeCT was 92% for nodal staging and 42% for extralymphatic staging when compared to FDG-PET. The specificity of CeCT was 98% as compared to FDG-PET. For response assessment, there was poor agreement between the CeCT and FDG-PET in assigning complete remission of disease scores as FDG-PET was able to identify the absence of disease despite the presence of a radiologically evident residual mass on CeCT. The sensitivity for CeCT compared to FDG-PET was 100% while the specificity was 43% for detection of post-treatment response.

Conclusion
For NLPHL, pre-therapeutic FDG-PET scan is better than CeCT staging. FDG-PET has much better specificity for response assessment than CeCT.

Authors: Andolina Jeffrey R. , Fries Carol , Boulware Renee , Vargas Alyssa , Fraint Ellen , Barth Matthew , Ambrusko Steven , Comito Melanie , Monteleone Philip 
Published: April 2021

Background:
Infant acute myeloid leukemia is a rare but aggressive form of leukemia.

Observation:
We report 2 children who presented with hyperleukocytosis, subsequently diagnosed with infant acute myeloid leukemia, and both developed isolated central nervous system relapse while on chemotherapy. Both infants underwent successful bone marrow transplantation with myeloablative conditioning (thiotepa, busulfan, and cyclophosphamide) without radiation, followed by 12 empiric post-transplant lumbar punctures with intrathecal cytarabine. Both patients tolerated these therapies well, and are without infections, chronic graft-versus-host disease, or any post-transplant sequelae.

Conclusion:
Nonradiation-based conditioning followed by empiric central nervous system-directed intrathecal chemotherapy may be considered for high-risk infants with leukemia.
Impact on periosteal vasculature after dual plating of the distal femur: a cadaveric study
Authors: Chen Michael J. , Goodnough Lawrence Henry , Salazar Brett P. , Gardner Michael J. 
Published: April 2021

Objectives:
Although dual plating of distal femur fractures has been described for injuries at risk of varus displacement, the vascular insult to the medial distal femur utilizing this technique is unknown. The aim of this study was to evaluate the perfusion of the medial distal femoral periosteal arteries after supplemental medial plating of the distal femur.

Methods:
Fifteen human fresh-frozen cadaveric femora were thawed and randomized to lateral locked plating alone or with supplemental medial plate fixation. Conventional submuscular medial plating was performed using a 12-hole small fragment plate and multiple cortical screws. The superficial femoral artery was injected with latex dye. Specimens were dissected. The patency of the medial distal femoral periosteal vessels was evaluated.

Results:
Four vessels were consistently observed traversing the distal medial femur: the transverse and descending (d-MMPA) branches of the medial metaphyseal periosteal artery, and the transverse and longitudinal branches of the descending geniculate artery. The anterior longitudinal arch (ALA) was present in 13 of 15 specimens and was fed by the d-MMPA. The median number of periosteal arteries occluded by the medial plate was 2 (6 out of 8 specimens). The d-MMPA was occluded in 6 of 8 medially plated femurs, resulting in a complete lack of perfusion of the ALA.

Conclusions:
Submuscular medial plating of the distal femur compressed the d-MMPA in the majority of specimens. This vessel gives rise to the ALA, which lacked perfusion in these specimens. This vascular insult could affect the healing of metaphyseal distal femur fractures treated with dual plating.
Understanding the “Swiss Cheese Model” and Its Application to Patient Safety
Authors: Wiegmann Douglas A. , Wood Laura J. , Cohen Tara N. , Shappell Scott A. 
Published: April 2021

Abstract
This article reviews several key aspects of the Theory of Active and Latent Failures, typically referred to as the Swiss cheese model of human error and accident causation. Although the Swiss cheese model has become well known in most safety circles, there are several aspects of its underlying theory that are often misunderstood. Some authors have dismissed the Swiss cheese model as an oversimplification of how accidents occur, whereas others have attempted to modify the model to make it better equipped to deal with the complexity of human error in health care. This narrative review aims to provide readers with a better understanding and greater appreciation of the Theory of Active and Latent Failures upon which the Swiss cheese model is based. The goal is to help patient safety professionals fully leverage the model and its associated tools when performing a root cause analysis as well as other patient safety activities.

Published: April 2021

Objective
The aim of the study was to determine the main factors contributing to hospital readmissions and their potential preventability after a coronavirus disease 2019 (COVID-19) hospitalization at 2 New York City hospitals.

Methods
This was a retrospective study at 2 affiliated New York City hospitals located in the Upper East Side and Lower Manhattan neighborhoods. We performed case reviews using the Hospital Medicine Reengineering Network framework to determine potentially preventable readmissions among patients hospitalized for COVID-19 between March 3, 2020 (date of first case) and April 27, 2020, and readmitted to either of the 2 hospitals within 30 days of discharge.

Results
Among 53 readmissions after hospitalization for COVID-19, 44 (83%) were deemed not preventable and 9 (17%) were potentially preventable. Nonpreventable readmissions were mostly due to disease progression or complications of COVID-19 (37/44, 84%). Main factors contributing to potentially preventable readmissions were issues with initial disposition (5/9, 56%), premature discharge (3/9, 33%), and inappropriate readmission (1/9, 11%) for someone who likely did not require rehospitalization.

Conclusions
Most readmissions after a COVID-19 hospitalization were not preventable and a consequence of the natural progression of the disease, specifically worsening dyspnea or hypoxemia. Some readmissions were potentially preventable, mostly because of issues with disposition that were directly related to challenges posed by the ongoing COVID-19 pandemic. Clinicians should be aware of challenges with disposition related to circumstances of the COVID-19 pandemic.
Epidemiology and Outcomes of Alcohol Use Hospitalizations in People With Gout, Rheumatoid Arthritis, Fibromyalgia, Osteoarthritis, or Low Back Pain
Authors: Singh Jasvinder A. 
Published: April 2021

Objective
To examine the incidence, time trends, and outcomes of alcohol use disorder (AUD) hospitalizations in people with gout, rheumatoid arthritis (RA), fibromyalgia, osteoarthritis, or low back pain (LBP).

Methods
We used the US National Inpatient Sample data from 1998 to 2016. We examined the rates of AUD hospitalizations in musculoskeletal diseases (MSDs), based on the presence of diagnostic codes for AUD in the primary and MSDs in a secondary position. Multivariable-adjusted (age, sex, race, and income) health care utilization and in-hospital mortality were compared by the presence/absence of MSDs, using linear or logistic regression.

Results
Alcohol use disorder hospitalizations increased over the 19-year study period from 1998 to 2014 to 3-fold higher in gout, osteoarthritis, or LBP; 3.5-fold in RA; and 4.5-fold in fibromyalgia. Compared with AUD hospitalizations in people without each respective MSD, adjusted total hospital charges were $3913 higher in people with gout and $1368 to $1614 lower for osteoarthritis, fibromyalgia, or LBP over the study period (all significant) and not significantly different for RA. The adjusted odds of hospital stay of more than 3 days were significantly higher for all 5 MSDs, with odds ratio ranging 1.10 for LBP to 1.34 for gout. The adjusted odds of in-hospital mortality were significantly lower for all 5 MSDs, with odds ratio ranging from 0.21 for fibromyalgia to 0.50 for gout.

Conclusions
In a national US study, the rate of AUD hospitalizations increased in all 5 MSDs. Providers and patients with MSDs should be counseled regarding the risk and impact of alcohol use. Interventions to reduce AUD hospitalization–associated health care burden in MSD are needed.
