RESUMEN

High-performance silk fibers, with their eco-friendly degradability and renewability, have long captivated researchers as an alternative to synthetic fibers. Spider dragline silk, renowned for its exceptional strength (>1 GPa), has an extremely low yield, hindering its widespread use. While domesticated silkworms (Bombyx mori) can produce silk fibers industrially, their moderate strength (≈0.5 GPa) pales in comparison to the formidable spider dragline silk. In this study, naturally produced strong silkworm silk fibers are reported with a tensile strength of ≈1.2 GPa achieved through combining feeding carbon nanotubes (CNTs) to silkworms and in situ forced reeling for alignment. Molecular dynamics simulations confirm the interaction between the CNTs and silk fibroin, while the forced reeling process aligns these reinforcing fillers and the silk fibroin ß-sheet nanocrystals along the fiber axis. Structural analysis reveals a significant enhancement in the content and alignment of ß-sheet nanocrystals within the silk fibers, accounting for their superior mechanical properties, including tensile strength of ≈1.2 GPa and Young's modulus of 24.4 GPa, surpassing various types of silkworm silk and spider silk. This advancement addresses the historical trade-off between the strength and scalability of silk, potentially paving the way for eco-friendly, biodegradable, and renewable alternatives to synthetic fibers in a variety of applications.

RESUMEN

Objective: In the RECO study, we investigated the impact of the operator's choice of stent retriever size on patients with internal carotid artery (ICA) occlusion. Methods: Data from the RECO Registry, a prospective multicentre study, were utilized. Patients who underwent mechanical thrombectomy (MT) were divided according to the size of the stent into the RECO 4 × 20 group, the RECO 5 × 30 group and the RECO 6 × 30 group. The outcome measures assessed in the study were the 3-month modified Rankin Scale (mRS) score, occurrence of any intracranial haemorrhage (aICH), workflow timing, recanalization success rate, number of attempts, and all-cause mortality within a 3-month period. Results: Analysis was conducted on a total of 89 patients with ICA occlusion. RECO 4 × 20, 5 × 30, and 6 × 30 stent retrievers were used in 19 (21.3%), 52 (58.4%), and 18 (20.2%) patients, respectively. The demographic and baseline characteristics showed considerable similarity across the three groups. The puncture-to-recanalization time of the RECO 6 × 30 group [56.5 min (IQR, 41.5-80.8)] was significantly shorter than that of the RECO 4 × 20 group [110 min (IQR, 47-135)]. In 10 out of 18 patients (55.6%), the RECO 6 × 30 stent retriever achieved reperfusion (modified Thrombolysis in Cerebral Infarction [mTICI] score 2b-3) after the initial attempt, surpassing the rates of 31.6% in the RECO 4 × 20 group and 32.7% in the RECO 5 × 30 group. In the RECO 4 × 20 group, the median number of passes was 2 (IQR, 1-3); in the RECO 5 × 30 group, it was 2 (IQR, 1-3); and in the RECO 6 × 30 groups, it was 1 (IQR, 1-2.5). There were no statistically significant differences observed among the three groups concerning aICH or good outcomes (mRS score 0-2). Conclusion: Our study demonstrated the practical implications of stent-retriever size selection in the context of the MT for ICA occlusion. The routine use of a RECO 6 × 30 stent retriever holds the potential for early revascularization in clinical practice. The significant reduction in the puncture-to-reperfusion time and the greater first-pass effect associated with this stent size underscore its efficiency in treating ICA occlusion.

RESUMEN

Background: Whether intravenous thrombolysis (IVT) should be bridged before mechanical thrombectomy (MT) remains uncertain in patients with large vessel occlusion (LVO) and chronic kidney disease (CKD). Methods: This research systematically enrolled every patient with both acute ischemic stroke (AIS) and CKD who received MT and fulfilled the criteria for IVT from January 2015 to December 2022. According to whether they underwent IVT, the patients were categorized into two cohorts: MT and combined IVT + MT. A binary logistic regression model was used to adjust for potential confounders, and propensity score matching analysis was used to assess the efficacy and safety of IVT in AIS patients with CKD who underwent MT. Results: A total number of 406 patients were ultimately included in this study, with 236 patients in the MT group and 170 in the combined group. After PSM, there were 170 patients in the MT group and 170 in the combined group, and the clinical characteristics between the two groups were well balanced. The MT + IVT group had better long-term functional outcomes than the MT group (35.9% versus 21.2%, P = 0.003) and more modified thrombolysis in cerebral infarction (mTICI) (2b-3) (94.1% versus 87.6%, P = 0.038), while no significant difference was found regarding symptomatic intracranial hemorrhage (sICH). In line with the results observed in the in the postmatched population, the logistic regression revealed that patients in the IVT + MT group demonstrated superior clinical outcomes (adjusted OR 0.440 [95% CI (0.267-0.726)], P = 0.001) in the prematched population. Conclusion: For LVO patients with CKD and indications for IVT, IVT bridging MT improves their prognosis compared with direct MT.

RESUMEN

The RECO is a novel endovascular treatment (EVT) device that adjusts the distance between two mesh segments to axially hold the thrombus. We organized this postmarket study to assess the safety and performance of RECO in acute ischaemic stroke (AIS) patients with large vessel occlusion (LVO). This was a single-arm prospective multicentre study that enrolled patients as first-line patients treated with RECO at 9 stroke centres. The primary outcome measures included functional independence at 90 days (mRS 0-2), symptomatic intracranial haemorrhage (sICH), time from puncture to recanalization and time from symptom onset to recanalization. The secondary outcome measures were a modified thrombolysis in cerebral infarction (mTICI) score of 2b or 3 after the first attempt and at the end of the procedure and the all-cause mortality rate within 90 days. From May 22, 2020, to July 30, 2022, a total of 268 consecutive patients were enrolled in the registry. The median puncture-to-recanalization time was 64 (IQR, 45-92), and the symptom onset-to-recanalization time was 328 min (IQR, 228-469). RECO achieved successful reperfusion (mTICI 2b-3) after the first pass in 133 of 268 patients (49.6%). At the end of the operation, 96.6% of the patients reached mTICI 2b-3, and 97.4% of the patients ultimately achieved successful reperfusion. Sixteen (7.2%) patients had sICH. A total of 132 (49.3%) patients achieved functional independence at 90 days, and the all-cause mortality rate within 90 days was 17.5%. In this clinical experience, the RECO device achieved a high rate of complete recanalization with a good safety profile and favourable 90-day clinical outcomes.Clinical trial registration: URL: https://www.clinicaltrials.gov/ ; Unique identifier: NCT04840719.

RESUMEN

While nanomaterials possess impressive mechanical properties at the microscale level, their macroscopic assemblies usually exhibit inferior properties due to ineffective stress transfer among individual nanomaterials. This issue is addressed in this work by achieving strong interfacial interactions between aramid nanofibers and graphene oxide nanosheets through a neutralization reaction in a dipolar solvent and regulating the topological properties using polymer micelles to form a compact structure, leading to the formation of a super-strong and super-tough nanofiber film. The film was prepared through a sol-gel-film transition process and possesses a nacre-like microstructure that deflects microcracks and prevents them from propagating straight through the film. Remarkably, it demonstrates a tensile strength of 599.0 MPa and a toughness of 37.7 MJ m-3, which are 491.0% and 1094.5% that of a pristine aramid nanofiber film, respectively. In addition, it exhibits excellent tolerance to extreme temperatures (-196 to 300 °C) and fatigue resistance to folding 10 000 times. Overall, this study presents a synergistic interfacial and topological enhancement strategy for constructing nanomaterial-based composites with inherited properties from the nanoscale building blocks to the macroscale structural material.

RESUMEN

A photoelectrochemical (PEC) transducer based on composite TiO2/PpIX/Ag@Cu2O was prepared for the detection of CYFRA 21-1. TiO2 nanomaterials were synthesized by hydrothermal method. TiO2/PpIX/Ag@Cu2O composites were obtained by combining protoporphyrin Ⅸ (PpIX) molecules and Ag@Cu2O on TiO2. This composite material has strong absorption in visible light region and excellent photoelectric chemical properties. Ascorbic acid (AA) is a good electron donor, which can remove photogenerated holes in liquid environment to inhibit the recombination of photogenerated electrons and hole pairs, thus enhancing the photocurrent and improving its stability. The results showed that the sensor can quantitatively test CYFRA 21-1 in the range of 0.1 pg/mL∼100 ng/mL. The photoelectric chemical sensor has the advantages of high sensitivity, low detection line limit and wide linear range.

RESUMEN

BACKGROUND: Polycystic ovary syndrome (PCOS) is a common reproductive endocrine disorder, which is characterized by insulin resistance (IR) and menstrual cycle disorders. IR is thought of as a pivotal cause of PCOS and related comorbidities. However, the link between IR and abnormal menstrual cycles in PCOS should be further studied. In this study, we clarified the dose-response relationship between IR and abnormal menstrual cycles in patients with PCOS. RESULTS: In this retrospective study including 140 patients with PCOS, we found that there was a dose-response relationship between the increased HOMA-IR index and the level of menstrual cycle disorders (1.61 [95%CI: 1.37-1.85] for normal menstruation, 2.02 [95%CI: 1.61-2.44] for oligomenorrhea, 2.35 [95%CI:1.96-2.75] for amenorrhea, P for trend = 0.003). Further stratification analyses showed that this dose-response relationship was more evident in the patients who were younger, had higher BMI, higher AFC numbers, elevated levels of testosterone, anti-Müllerian hormone, inhibin B, and prolactin levels, and had a lower progestogen level. CONCLUSIONS: Our study has established an association between IR and abnormal menstrual cycles in patients with PCOS, which can be affected by age, BMI, and hormone levels. Our results might be helpful for further prevention and treatment of amenorrhea in PCOS.

RESUMEN

A fetal posterior cerebral artery (FPCA) is an anatomic variant in which the posterior cerebral artery (PCA) is an embryological derivative of the internal carotid artery (ICA). Patients with FPCA may experience posterior circulation stroke (PCS) after a thrombotic event in the ICA system, while exclusively PCS caused by thrombosis of the ICA has rarely been reported. We report a patient with FPCA and summarize 3 types of exclusively PCS caused by FPCA due to thrombotic events in the ICA system. Type A: the thrombus involves the opening of the FPCA and obstructs the blood flow of the entire ICA. The contralateral ICA compensates the ipsilateral middle cerebral artery (MCA) and anterior cerebral artery (ACA) through the anterior communicating artery (ACOM). Type B: the thrombus involves the opening of the FPCA but does not block the blood flow of the entire ICA, which still perfuses the ipsilateral ACA and MCA. Type C: the thrombus only involves the FPCA and not the ipsilateral ICA. Patients with types A and B may obtain a good prognosis through endovascular treatment (EVT), while the benefits of this procedure in type C patients are unclear.

RESUMEN

PURPOSE: The relationship between menarche age and endometriosis has been studied extensively; however, the results were inconsistent due to differences in study dates, populations, and methodology. The goal of this meta-analysis was to see how different research populations, dates, and types affected the estimated risk of endometriosis in early menarche. METHODS: The terms "endometriosis", "early menarche", and other pertinent terms were searched in PubMed, Medline, and Embase. This meta-analysis comprised 16 papers published between 2000 and 2020, with a start year ranging from 1989 to 2017. Random effects were used to examine endometriosis risks in these articles. Study start years, countries, types (case-control and cohort studies), and quality (Newcastle-Ottawa scale, NOS) were all taken into account in further stratified analysis and meta-regression analyses. RESULTS: Early menarche (< 12 years) was associated with a significant pooled risk of endometriosis with high heterogeneity (OR = 1.34, 95% CI 1.16-1.54, I2 = 72.0%). Stratified analysis showed that this risk was increased in studies started after 2000 (OR = 1.62, 95% CI 0.96-1.35, I2 = 74.4%), compared to those before 2000 (OR = 1.13, 95% CI 1.16-1.54, I2 = 40.7%); additionally, this risk was higher in low-income countries (OR = 2.11, 95% CI 1.55-2.87, I2 = 0%) than in other countries (OR = 1.25, 95% CI 1.09-1.43, I2 = 70.6%). These results were further confirmed by meta-regression analysis (both P values < 0.1). No significant differences were found between different study types and NOS scores. CONCLUSION: Our results suggested an increasing risk of endometriosis with early menarche, which was more noticeable in low-income countries. Large-scale studies are warranted.

RESUMEN

DNA methylation is a part of the regulatory mechanisms of gene expression, including chromatin remodeling and the activity of microRNAs, which are involved in the regulation of T-cell differentiation and function. However, the role of cfDNA methylation in T-cell differentiation is entirely unknown. In patients with endometrial polyps (EPs), we have found an imbalance of T-cell differentiation and an aberrant cfDNA methylation profile, respectively. In this study, we investigated the relationship between cfDNA methylation profiles and T-cell differentiation in 14 people with EPs and 27 healthy controls. We found that several differentially methylated genes (DMGs) were associated with T-cell differentiation in people with EPs (ITGA2-Naïve CD4, r = -0.560, p = 0.037; CST9-EMRA CD4, r = -0.626, p = 0.017; and ZIM2-CM CD8, r = 0.576, p = 0.031), but not in healthy controls (all p > 0.05). When we combined the patients' characteristics, we found a significant association between ITGA2 methylation and polyp diameter (r = 0.562, p = 0.036), but this effect was lost when adjusting the level of Naïve CD4 T-cells (r = 0.038, p = 0.903). Moreover, the circulating sex hormone levels were associated with T-cell differentiation (estradiol-Naïve CD4, r = -0.589, p = 0.027), and the cfDNA methylation profile (testosterone-ZIM2, r = -0.656, p = 0.011). In conclusion, this study has established a link between cfDNA methylation profiles and T-cell differentiation among people with EPs, which may contribute to the etiology of EPs. Further functional studies are warranted.

RESUMEN

BACKGROUND: Chronic kidney disease (CKD) is associated with a higher mortality rate and a poor prognosis among patients with acute ischemic stroke (AIS) who receive intravenous thrombolysis (IVT); however, it is still unclear whether IVT improves the prognosis of patients with AIS and CKD. OBJECTIVE: We conducted this study to evaluate the impact of IVT in patients with AIS and CKD. METHODS: We analyzed patients with AIS and CKD in 3 stroke centers who met the indications for IVT between January 2015 and January 2020. The patients were grouped into an IVT group and a non-IVT group according to whether patients received IVT. After propensity score matching at a 1:1 ratio, symptomatic intracranial hemorrhage (sICH) and the modified Rankin Scale (mRS) score at 3 months were compared to assess the safety and efficacy of IVT in patients with AIS with CKD. RESULTS: A total of 888 patients were enrolled: 763 in the IVT group and 125 in the non-IVT group. After matching, 250 patients were analyzed, and no significant differences were found in sICH between the 2 groups. However, the IVT group had a better 90-day mRS (0-2) score (70.4% vs. 57.6; p = 0.048) than the non-IVT group. CONCLUSIONS: IVT improved the 3-month prognosis and did not increase the occurrence of sICH among patients with AIS with CKD.

RESUMEN

OBJECTIVE: Stroke-associated pneumonia is an infection that commonly occurs in patients with spontaneous intracerebral hemorrhage and causes serious burdens. In this study, we evaluated the validity of the Braden scale for predicting stroke-associated pneumonia after spontaneous intracerebral hemorrhage. METHODS: Patients with spontaneous intracerebral hemorrhage were retrospectively included and divided into pneumonia and no pneumonia groups. The admission clinical characteristics and Braden scale scores at 24 h after admission were collected and compared between the two groups. Receiver operating characteristic curve analysis was performed to assess the predictive validity of the Braden scale. Multivariable analysis was conducted to identify the independent risk factors associated with pneumonia after intracerebral hemorrhage. RESULTS: A total of 629 intracerebral hemorrhage patients were included, 150 (23.8%) of whom developed stroke-associated pneumonia. Significant differences were found in age and fasting blood glucose levels between the two groups. The mean score on the Braden scale in the pneumonia group was 14.1±2.4, which was significantly lower than that in the no pneumonia group (16.5±2.6), p<0.001. The area under the curve for the Braden scale for the prediction of pneumonia after intracerebral hemorrhage was 0.760 (95%CI 0.717-0.804). When the cutoff point was 15 points, the sensitivity was 74.3%, the specificity was 64.7%, the accuracy was 72.0%, and the Youden's index was 39.0%. Multivariable analysis showed that a lower Braden scale score (OR 0.696; 95%CI 0.631-0.768; p<0.001) was an independent risk factor associated with stroke-associated pneumonia after intracerebral hemorrhage. CONCLUSION: The Braden scale, with a cutoff point of 15 points, is moderately valid for predicting stroke-associated pneumonia after spontaneous intracerebral hemorrhage.

RESUMEN

The RNA-binding protein LIN28B is an important factor for cell proliferation. Because LIN28B polymorphisms have been shown to be relative with the recurrence of some hyperplastic diseases, we hypothesized that genetic variants of LIN28B gene were associated with postoperative recurrence risk in reproductive-age women with endometrial polyps (EP). In a hospital-based cohort of 351 reproductive female patients underwent hysteroscopic polypectomies between May 2018 and Jan 2020, we genotyped two common polymorphisms in LIN28B gene (rs369065 C > T and rs314280 A > G) and analyzed their associations with the risk of postoperative recurrence in multiple Cox regression model. When followed up to Jun 2021, carries of rs369065 TT genotype had an increased risk of polyp recurrence (adjusting hazard ratio [HR] = 1.883, 95% confidence interval [CI] = 1.033 - 3.434) and had a shorter time to recurrence (median time 352 vs. 342 days, log-rank P < 0.01), compared to the CC/CT genotype. Further stratification analysis showed that the increased risk of rs369065 TT genotype was more evident in patients who were older than 33 years (adjusted HR = 2.597, 95%CI = 1.037 - 6.505), had a single polyp (adjusted HR = 2.545, 95%CI = 1.059 - 6.113), and had smaller polyps (<1.2 cm, adjusted HR = 2.708, 95%CI = 1.042 - 7.043). However, no significant association between rs314280 A > G polymorphism and the risk of polyp recurrence was found. Our study suggests that rs369065 TT genotype of LIN28B gene is associated with an increased postoperative recurrence risk in EP patients, especially in those with fewer and smaller polyps. These findings implicate a precise choice of clinical counseling and decision making. Larger studies in different ethnic populations are warranted.

RESUMEN

BACKGROUND: We aimed to conduct a meta-analysis to assess the impact of coronavirus disease 2019 (COVID-19) on college students' physical activity. METHODS: All cohort studies comparing college students undertaking physical exercise at school before the COVID-19 pandemic and physical exercise at home during the COVID-19 pandemic will be included in this review. We will use index words related to college students, physical exercise, and COVID-19 to perform literature searches in the PubMed, Medline, Embase, and CNKI databases, to include articles indexed as of June 20, 2021, in English and Chinese. Two reviewers will independently select trials for inclusion, assess trial quality, and extract information for each trial. The primary outcomes are exercise frequency, duration, intensity, and associated factors. Based on the Cochrane assessment tool, we will evaluate the risk of bias of the included studies. Revman 5.3 (the Cochrane collaboration, Oxford, UK) will be used for heterogeneity assessment, data synthesis, subgroup analysis, sensitivity analysis, and funnel plot generation. RESULT: We will discuss the impact of COVID-19 on college students' physical activity. CONCLUSION: Stronger evidence about the impact of COVID-19 on college students' physical activity will be provided to better guide teaching practice.

RESUMEN

OBJECTIVE: To explore the alteration of pattens of anatomical and functional connectivity (FC) of posterior cingulate cortex (PCC) in Parkinson's disease (PD) patients with cognitive dysfunction and the relationship between the connection strengths and cognitive state. METHODS: We prospectively enrolled 20 PD patients with mild cognitive impairment (PD-MCI), 13 PD patients with normal cognition (PD-NC) and 13 healthy controls (HCs). By collecting, preprocessing and FC analyzing resting-state functional magnetic resonance imaging (rs-fMRI) data, we extracted default mode network (DMN) patterns, compared the differences in DMN between the three groups and the analyzed the correlation between FC value with the commonly used neuropsychological testing. RESULTS: The PD-MCI showed significant worse performances in general cognition, and PD-NC and HCs showed comparable performances of cognitive function. Cognitive-related differences in DMN were detected in the bilateral precuneus (BPcu). Compared with the HCs, PD-NC and PD-MCI showed significantly decreased FC within BPcu (both P < 0.001). For PD-MCI, the rho of the Fisher's Z-transformed FC (zFC) value within BPcu with the TMTA, DSST and CFT-20min were 0.50, 0.66 and 0.47, respectively. For PD-NC, the rho of the zFC value within BPcu with the MMSE was 0.58. DISCUSSION: BPcu was the cognitive-related region in DMN. As cognition declines, FC within BPcu weakens. For PD-MCI, the higher the FC values within BPcu were likely to be related to the better the performances of TMTA, DSST and CFT-20 min DR, which needs to be further confirmed by large-sample studies.

RESUMEN

Systemic lupus erythematosus (SLE) is a systemic autoimmune disease with multiple autoantibody production and often affects the kidneys, known as lupus nephritis. However, the mechanism underlying lupus nephritis development is unclear. Biofilms that protect bacteria from stress are ubiquitous in almost every environment. Here, we identified that a conserved peptide (HU1) derived from DNABII proteins, one of major bacterial biofilm components, was specifically recognized by sera from about 47% patients with SLE. Moreover, the serum anti-HU1 levels showed a significant positive correlation with lupus nephritis occurrence. Presence of antibodies against HU1 in pristane-induced mice aggravated lupus nephritis, although these antibodies also attenuated bacterial biofilm formation. We further identified that antibodies against HU1 cross-recognized protein disulfide isomerase (P4HB) located on the renal cell surface and inhibited the activities of this enzyme. Our findings reveal a novel mechanism underlying the development of lupus nephritis triggered by bacterial biofilms.

RESUMEN

Background: There may be a delay in or a poor outcome of endovascular treatment (EVT) among acute ischemic stroke (AIS) patients with large-vessel occlusion (LVO) during off-hours. By using a prospective, nationwide registry, we compared the workflow intervals and radiological/clinical outcomes between patients with acute LVO treated with EVT presenting during off- and on-hours. Methods: We analyzed prospectively collected Endovascular Treatment Key Technique and Emergency Work Flow Improvement of Acute Ischemic Stroke (ANGEL-ACT) data. Patients presenting during off-hours were defined as those presenting to the emergency department from Monday to Friday between 17:30 and 08:00, on weekends (from 17:30 on Friday to 08:00 on Monday), and on national holidays. We used logistic regression models with adjustment for potential confounders to determine independent associations between the time of presentation and outcomes. Results: Among 1,788 patients, 1,079 (60.3%) presented during off-hours. The median onset-to-door time and onset-to-reperfusion time were significantly longer during off-hours than during on-hours (165 vs. 125 min, P = 0.002 and 410 vs. 392 min, P = 0.027). The rates of successful reperfusion and symptomatic intracranial hemorrhage were similar in both groups. The adjusted odds ratio (OR) for the 90-day modified Rankin Scale score was 0.892 [95% confidence interval (CI), 0.748-1.064]. The adjusted OR for the occurrence of functional independence was 0.892 (95% CI, 0.724-1.098), and the adjusted OR for mortality was 1.214 (95% CI, 0.919-1.603). Conclusions: Off-hours presentation in the nationwide real-world registry was associated with a delay in the visit and reperfusion time of EVT in patients with AIS. However, this delay was not associated with worse functional outcomes or higher mortality rates. Clinical Trial Registration: URL: https://www.clinicaltrials.gov; Unique identifier: NCT03370939.

RESUMEN

BACKGROUND: We aimed to conduct a meta-analysis to assess the effect of pharmaceutical care on the treatment of coronavirus disease 2019 (COVID-19). METHODS: All case-controlled studies related to pharmaceutical care on the treatment of COVID-19 will be included in this review. We will use index words related to pharmaceutical care and COVID-19 to perform literature searches in PubMed, Embase, MEDLINE, CNKI, and Wanfang databases, to include articles indexed as of October 20, 2020 in English and Chinese language. Two reviewers will select trials independently for inclusion and assess trial quality. Two pairs of review authors will independently extract information for each included trials. Primary outcomes are clinical outcomes, average hospital stays, costs, patient satisfaction, and incidence of adverse drug reactions. We will evaluate the risk of bias of the included studies based on Cochrane assessment tool. Revman 5.3 (the Cochrane collaboration, Oxford, UK) will be used for heterogeneity assessment, generating funnel-plots, data synthesis, subgroup analysis, and sensitivity analysis. RESULTS: We will provide targeted and practical results assessing the effect of pharmaceutical care on the treatment of COVID-19. CONCLUSION: The stronger evidence about the effect of pharmaceutical care on the treatment of COVID-19 will be provided for clinicians. SYSTEMATIC REVIEW REGISTRATION NUMBER: PROSPERO CRD42020214223 ETHICS AND DISSEMINATION:: There is no need for ethical approval, and the review will be reported in a peer-reviewed journal.
