Abstract
Cardiac amyloidosis (CA) is an increasingly recognized cause of heart failure, arrhythmias, and sudden cardiac death. While CA was previously rapidly fatal, recent advances in diagnosis and treatment have significantly improved outcomes. Advances in cardiac imaging and biomarkers have critically improved the accuracy and efficiency with which CA is diagnosed, even allowing for the noninvasive diagnosis of transthyretin CA. Cardiac magnetic resonance imaging, technetium nuclear imaging, echocardiography, and blood‐based biomarkers have established important and complementary roles in the management and advancement of care. At the same time, the development of novel targeted amyloid therapies has allowed patients with CA to live longer and potentially achieve better quality of life. Still, despite this significant progress, there remain critical ongoing questions in the field. Accordingly, within this review we will highlight recent advances in cardiac imaging and therapeutics for CA, while focusing on key opportunities for further optimization of care and outcomes among this growing population. Specifically, we will discuss ongoing debates in the diagnosis of CA, including the interpretation of indeterminate cardiac imaging findings, the best technique to screen asymptomatic transthyretin amyloidosis gene mutation carriers for cardiac involvement, and the ideal method for monitoring response to CA treatment. We will additionally focus on recent advances in treatment for transthyretin amyloidosis‐CA, including a discussion of available agents as well as highlighting ongoing clinical trials. Together, these data will allow clinicians to emerge with a greater understanding of the present and future of diagnosis, management, and potentially enhanced outcomes in this rapidly advancing field.

AbstractDevastating Japan in October 2019, Supertyphoon (STY) Hagibis was an important typhoon in the history of the Pacific. A striking feature of Hagibis was its explosive rapid intensification (RI). In 24 h, Hagibis intensified by 100 knots (kt; 1 kt ≈ 0.51 m s−1), making it one of the fastest-intensifying typhoons ever observed. After RI, Hagibis’s intensification stalled. Using the current typhoon intensity record holder, i.e., STY Haiyan (2013), as a benchmark, this work explores the intensity evolution differences of these two high-impact STYs. We found that the extremely high prestorm sea surface temperature reaching 30.5°C, deep/warm prestorm ocean heat content reaching 160 kJ cm−2, fast forward storm motion of ∼8 m s−1, small during-storm ocean cooling effect of ∼0.5°C, significant thunderstorm activity at its center, and rapid eyewall contraction were all important contributors to Hagibis’s impressive intensification. There was 36% more air–sea flux for Hagibis’s RI than for Haiyan’s. After its spectacular RI, Hagibis’s intensification stopped, despite favorable environments. Haiyan, by contrast, continued to intensify, reaching its record-breaking intensity of 170 kt. A key finding here is the multiple pathways that storm size affected the intensity evolution for both typhoons. After RI, Hagibis experienced a major size expansion, becoming the largest typhoon on record in the Pacific. This size enlargement, combined with a reduction in storm translational speed, induced stronger ocean cooling that reduced ocean flux and hindered intensification. The large storm size also contributed to slower eyewall replacement cycles (ERCs), which prolonged the negative impact of the ERC on intensification.

Published: April 2021

Objective: To assess the effect of platelet-rich plasma as a conservative therapy in individuals with partial-thickness rotator cuff tears or tendinopathy on pain, and function. Data sources: Embase, MEDLINE, CENTRAL, Web of Science, CINAHL, PEDro, and the grey literature (to 31 March 2021). Methods: Randomized controlled trials in English that reported short-term (6 ± 1 months), or long-term (⩾1 year) outcomes (shoulder pain or function) were conducted. Two independent reviewers screened the literature, completed the assessment of the Cochrane’s risk of bias and extracted the data. Mean difference or standardized mean difference was used for continuous data. Heterogeneity was identified with I2 test. Results: A total of 11 studies were eligible, and nine studies ( n = 629) were included in this meta-analysis, that showed statistically significant short-term effects of platelet-rich plasma on pain relief (MD = −1.56; 95% CI −2.82 to −0.30), Constant-Murley score (MD = 16.48; 95% CI 12.57 to 20.40), and Shoulder Pain and Disability Index (MD = −18.78; 95% CI −36.55 to −1.02). Nonetheless, no long-term effect was observed on pain and function, except Constant-Murley score (MD = 24.30; 95% CI 23.27 to 25.33). The results of minimal important difference reached the minimal clinically important difference, except American Shoulder and Elbow Surgeons. For subgroup analysis, differences of pain relief were statistically significant in platelet-rich plasma-treated groups with double centrifugation, single injection, and post-injection rehabilitation. Conclusion: Our results suggested platelet-rich plasma had positive effects on pain relief and functional improvement for partial-thickness rotator cuff tears and rotator cuff tendinopathy, although the effects may not last for a long time.

Objective This study aimed to investigate the predictive value of inflammatory cells in peripheral blood on the prognosis of patients with acute coronary syndrome (ACS) undergoing percutaneous coronary intervention (PCI). Methods Patients (n=1558) were consecutively enrolled and the median follow-up was 1142 days. Patients were divided into the major adverse cardiac events (MACE) 1 group (n=63) (all-cause mortality [n=58] and rehospitalization for severe heart failure [n=5], no MACE1 group (n=1495), MACE2 group (n=38) (cardiac mortality [n=33] and rehospitalization for severe heart failure [n=5]), and no MACE2 group (n=1520). The neutrophil-to-lymphocyte ratio (NLR), monocyte-to-lymphocyte ratio (MLR), and platelet-to-lymphocyte ratio (PLR) were analyzed. Results The NLR, MLR, and PLR were higher in the MACE groups than in the no MACE groups. Different subsets of inflammatory cells had similar diagnostic values for MACE. Kaplan–Meier curves showed that the survival time gradually decreased with an increase in the degree of risk as determined by the NLR, MLR, and PLR. The risk of MACE was highest in the extremely high-risk group. Conclusion Peripheral blood inflammatory cell subsets can predict MACE in patients with ACS undergoing PCI. These cell subsets could be important laboratory markers for the prognosis and clinical treatment of these patients.

Introduction: Despite the importance of compassionate leadership in health care, many of the existing publications do not account for the effect of culture. The aim of this study is to explore the views of nursing and midwifery managers from different countries in relation to the definition, advantages, and importance of compassion. Methodology: A cross-sectional, descriptive, exploratory online survey was conducted across 17 countries, containing both closed and open-ended questions. Data from N = 1,217 respondents were analyzed using a directed hybrid approach focusing only on qualitative questions related to compassion-giving. Results: Four overarching themes capture the study’s results: (1) definition of compassion, (2) advantages and importance of compassion for managers, (3) advantages and importance of compassion for staff and the workplace, and (4) culturally competent and compassionate leadership. Discussion: Innovative research agendas should pursue further local qualitative empirical research to inform models of culturally competent and compassionate leadership helping mangers navigate multiple pressures and be able to transculturally resonate with their staff and patients.

Background Although antibody-mediated rejection (AMR) is described in other solid organ transplant populations, the literature describing the management following lung transplantation is limited. Objective The purpose of this study is to evaluate the management strategies of AMR in lung transplant recipients. Methods This single-center, retrospective study described the management of AMR in adult lung transplant recipients who received treatment with rabbit antithymocyte globulin, bortezomib, rituximab, intravenous immune globulin (IVIG), and/or plasmapheresis between September 2015 and June 2019. Results A total of 270 medication orders for 55 patient admissions were included in the primary outcome analysis. The most commonly used regimen consisted of IVIG, plasmapheresis, and rituximab (49.1%; n = 27), followed by IVIG and plasmapheresis alone (27.3%, n = 15). A total of 51 patients (93%) received plasmapheresis as part of their AMR treatment, with a median of 4 [3, 5] sessions per encounter; 86% of patients with positive donor-specific antibodies (DSAs) had a reduction in DSAs following AMR treatment. Overall, 23.5% of patients had noted allograft failure or need for retransplantation. A total of 10 patients died during the AMR treatment hospital admission, and an additional 11 patients died within 1 year of the initial encounter. Conclusion and Relevance This represents the largest report describing management strategies of AMR in lung transplant recipients. Although practice varied, the most commonly used regimen consisted of plasmapheresis, IVIG, and rituximab.

Published: April 2021

Purpose Open surgical repair of type Ia endoleak after endovascular aortic aneurysm repair/sealing (EVAR/EVAS) is associated with significant perioperative mortality and morbidity. Current endovascular redo techniques face limitations, especially when the infrarenal landing zone is inadequate and the previous endograft is rigid and features a short or no main body. We present a novel concept for the treatment of type Ia endoleak using a custom-made branched device. Technique The 5-branch-device (Cook Medical, Bloomington, IN, USA) consists of a nitinol skeleton with branches, covered with a low-profile polyester fabric loaded in an 18F sheath. The device features a minimum of 2 proximal sealing stents and includes branches for renovisceral vessels as well as an additional 8 mm branch for the contralateral iliac limb. Implantation and sealing in the renovisceral vessels is carried out in standard fashion, using transfemoral and transaxillary access. Distal sealing is achieved by tapering the branched component into the ipsilateral iliac limb and using a bridging balloon-expandable or self-expandable stent-graft through the additional branch to the preexisting contralateral iliac limb. Conclusion Treatment of type Ia endoleak with a new custom-made device enables sufficient proximal seal while minimizing suprarenal aortic coverage and facilitates adequate component overlap. The low profile branched design accommodates implantation through the preexisting endograft and catheterization of target vessels.

Aim: Intensity-modulated radiotherapy (IMRT) is a widely accepted therapy for nasopharyngeal carcinoma (NPC), but it inevitably brings out radiation-related complications and seriously affects the quality of life (QoL). Endoscopic nasopharyngectomy (ENPG) has been successfully conducted in locally recurred NPC, but few studies evaluated its application in early NPC. This study aims to assess the feasibility and safety of ENPG combined with low-dose radiotherapy (LDRT) in T1-2 NPC. Patients and Methods: We recruited 37 newly diagnosed localized T1-2 NPC patients who voluntarily accepted ENPG +LDRT from June 2013 to September 2016. Meanwhile, the data of 132 T1-2 NPC patients treated with IMRT were collected and used as control group. The survival outcomes, QoL score and late RT-related sequelaes were compared between the 2 groups. Results: After a median follow-up of 54 months, only 1 patient in ENPG+LDRT group died along with hepatic metastases. The 5-year overall survival, distant metastasis-free survival, local relapse-free survival and regional relapse-free survival in ENPG+LDRT group were 97.3%, 97.3%, 100% and 100%, which were not statistically different from the control group (97.7%, 90.2%, 95. 5%, 97.0%, respectively, all P > 0.05). In comparison with IMRT group, ENPG+LDRT exhibited better QoL and less rate of late RT-related sequlaes including hearing loss (53.8% vs 27.0%, P = 0.005), xerostomia (46.2% vs 24.3%, P = 0.023) and dysphagia (25.8% vs 8.1%, P = 0.024). Conclusions: ENPG+LDRT provided satisfactory survival outcomes, and improved the QoL and reduced the incidence of sequelae for T1-2 NPC patients.

Published: April 2021

Background and Objective: Mercury is one of the most harmful heavy metals and its toxicity causes severe multi-organ dysfunction. This study was designed to explore novel molecular pathways involved in the hepatoprotective effect of vitamin E (Vit-E) and Lactobacillius plantarum (Lac-B) against mercury toxicity.[Formula: see text] Method: Acute hepatotoxicity was induced by administration of high dose of mercuric chloride (HgCl2) in male rats, Vit-E or/and Lac-B were given along with HgCl2 for 2 weeks. The effects of those antioxidants were studied focusing on their anti-apoptotic, anti-oxidative stress and anti-inflammatory eficacies. Histopathological examinations were also conducted. Results: The administration of HgCl2 induced liver injury which manifested by elevation in serum ALT and AST. Liver MDA, caspase-3 and TNF-α levels were markedly increased; whereas, GSH level and SOD activity were declined. HgCl2 significantly elevated the expressions of hepatic CHOP, GPR87, NF-κB and mTOR. Histopathological examination revealed massive hepatocyte degeneration following HgCl2 administration. Treatment with Vit-E or/and Lac-B restored the normal levels of the previously mentioned parameters, as well as improved hepatic architecture. Conclusion: Vit-E and Lac-B provided protective effect against HgCl2-induced hepatotoxicity via reduction of oxidative stress and inflammation, and downregulation of CHOP, GPR87, NF-κB and mTOR proteins’ expressions.

Background Recent in vitro and clinical studies have shown that ultrasound-accelerated catheter-directed thrombolysis (USACDT) can accelerate thrombolysis. Therefore, in this meta-analysis, we aimed to compare the efficacy and safety of USACDT with conventional catheter-directed thrombolysis in patients with deep vein thrombosis. Methods A systematic search of the following electronic databases was performed from their dates of inception to 20 June 2020: MEDLINE, Scopus, Google Scholar, CINAHL, Cochrane Library, and EMBASE. All randomized controlled trials that directly compared the complications and efficacy of USACDT and conventional catheter-directed thrombolysis in patients with deep vein thrombosis were identified. The statistical analysis was performed using comprehensive meta-analysis software. Results Finally, 18 studies with a total of 597 participants were included in our meta-analysis according to the eligibility criteria. Pooled proportion of USACDT success in patients with deep vein thrombosis was 87.8% (18 studies; 95% CI: 83.1–91.3). Success rate was significantly higher in USACDT treatment than in conventional catheter-directed thrombolysis treatment (seven studies; OR: 2.96; 95% CI: 1.69–5.16; P < 0.01)). Although the mean infusion time was higher in catheter-directed thrombolysis treatment compared to USACDT treatment, this difference was not statistically significant (three studies; MD: –1.46; 95% CI: –3.25–0.32; P = 0.10). Moreover, pooled rate of complications was lower in USACDT than catheter-directed thrombolysis which was not statistically significant (seven studies; OR: 0.49; 95% CI: 0.13–1.76; P = 0.27). Conclusion This meta-analysis revealed that USACDT significantly increased the success rate of thrombolysis compared to conventional catheter-directed thrombolysis. Furthermore, USACDT was associated with lower rate of complication and infusion time. Taken together, these findings confirm the superiority of this novel intervention over conventional catheter-directed thrombolysis in treatment of patients with deep vein thrombosis.

Objective To characterize the association of preoperative functional performance status based on Eastern Cooperative Oncology Group (ECOG) scoring with the risk of adverse cardiovascular events, vascular events, and mortality in patients undergoing EVAR and TEVAR. Methods Retrospective review of the Society for Vascular Surgery Vascular Quality Initiative, a large, multi-center, registry database was performed. All individuals undergoing EVAR ( n = 18,730) and TEVAR ( n = 6595) for non-ruptured aortic pathologies between 2014 and 2018 were eligible for analysis. Multivariable logistic regression was used to determine the association of pre-procedure ECOG functional performance status on risk of in-hospital adverse cardiovascular events, vascular events, and mortality. Results The number of operations complicated by adverse cardiovascular and vascular events was 480 (2.6%) and 190 (1.0%) for EVAR and 733 (11.1%) and 219 (3.3%) for TEVAR, respectively. There were 118 (0.6%) and 240 (3.6%) in-hospital deaths following EVAR and TEVAR, respectively. Patients with ECOG grades 3 or 4 undergoing EVAR were at increased risk of cardiovascular events (OR = 1.62; 95% CI = 1.09, 2.41) and one-year mortality (HR = 2.62; 95% CI = 1.92, 3.57) compared to those with ECOG grade 0. Patients undergoing TEVAR with ECOG grade 3 or 4 were at increased risk for both inpatient death (OR = 2.77; 95% CI = 1.56, 4.9) and one-year mortality (HR = 3.27, 95% CI = 2.06, 5.21). ECOG status was not associated with an increased risk of adverse vascular events following either EVAR or TEVAR. Conclusions Poor preoperative functional status as assessed by ECOG score is associated with an increased risk of adverse postoperative cardiovascular events following EVAR and a higher mortality risk following both EVAR and TEVAR. Functional status assessment may be useful for risk stratification and determining procedural candidacy prior to EVAR and TEVAR.

Published: April 2021

Background It is well-documented that women tend to be worse off post-stroke. They are often frailer, have less independence, lower functionality, increased rates of depression, and overall a lower quality of life. People who have had strokes benefit from rehabilitative support to increase their independence and reduce the risk of stroke reoccurrence. Despite the gender differences in the effects of stroke, interventions explicitly aimed at helping women have not been identified. Purpose This systematic review aimed to summarize the effectiveness of the health promoting behavioural interventions for reducing risk factors and improved self-management in women post-stroke, compared to usual care. Method Seven databases, Medline (Ovid), CINAHL, PsychInfo, Embase, PubMed, Scopus, and Google Scholar, were reviewed for randomized controlled trials covering post-stroke interventions. The following keywords were used: health promotion, secondary prevention, woman, women, female, sex difference, gender difference, after stroke, and post-stroke. Results Ten randomised controlled trials were found. These demonstrated common successful approaches for rehabilitation, but none specifically described health promotion strategies for women. Core components of successful programs appeared to be a structured approach, tailored to clientele and formalised support systems through their carer, family networks, or community engagement. Comprehensive reminder systems were successful for stroke risk reduction. Conclusion Women are disproportionately affected by stroke and are often in the frail category. Tailored structured health promotion programs with family and caregiver support combined with a comprehensive reminder system would appear to enable women post-stroke.
