RESUMO

BACKGROUND: Medical encounters require an efficient and focused history of present illness (HPI) to create differential diagnoses and guide diagnostic testing and treatment. Our aim was to compare the HPI of notes created by an automated digital intake tool versus standard medical notes created by clinicians. METHODS: Prospective trial in a quaternary academic Emergency Department (ED). Notes were compared using the 5-point Physician Documentation Quality Instrument (PDQI-9) scale and the Centers for Medicare & Medicaid Services (CMS) level of complexity index. Reviewers were board certified emergency medicine physicians blinded to note origin. Reviewers received training and calibration prior to note assessments. A difference of 1 point was considered clinically significant. Analysis included McNemar's (binary), Wilcoxon-rank (Likert), and agreement with Cohen's Kappa. RESULTS: A total of 148 ED medical encounters were charted by both digital note and standard clinical note. The ability to capture patient information was assessed through comparison of note content across paired charts (digital-standard note on the same patient), as well as scores given by the reviewers. Reviewer agreement was kappa 0.56 (CI 0.49-0.64), indicating moderate level of agreement between reviewers scoring the same patient chart. Considering all 18 questions across PDQI-9 and CMS scales, the average agreement between standard clinical note and digital note was 54.3% (IQR 44.4-66.7%). There was a moderate level of agreement between content of standard and digital notes (kappa 0.54, 95%CI 0.49-0.60). The quality of the digital note was within the 1 point clinically significant difference for all of the attributes, except for conciseness. Digital notes had a higher frequency of CMS severity elements identified. CONCLUSION: Digitally generated clinical notes had moderate agreement compared to standard clinical notes and within the one point clinically significant difference except for the conciseness attribute. Digital notes more reliably documented billing components of severity. The use of automated notes should be further explored to evaluate its utility in facilitating documentation of patient encounters.

RESUMO

The incidence of aortic valve stenosis (AS), the most common reason for aortic valve replacement (AVR), increases with population ageing. While untreated AS is associated with high mortality, different hemodynamic subtypes range from normal left-ventricular function to severe heart failure. However, the molecular nature underlying four different AS subclasses, suggesting vastly different myocardial fates, is unknown. Here, we used direct proteomic analysis of small left-ventricular biopsies to identify unique protein expression profiles and subtype-specific AS mechanisms. Left-ventricular endomyocardial biopsies were harvested from patients during transcatheter AVR, and inclusion criteria were based on echocardiographic diagnosis of severe AS and guideline-defined AS-subtype classification: 1) normal ejection fraction (EF)/high-gradient; 2) low EF/high-gradient; 3) low EF/low-gradient; and 4) paradoxical low-flow/low-gradient AS. Samples from non-failing donor hearts served as control. We analyzed 25 individual left-ventricular biopsies by data-independent acquisition mass spectrometry (DIA-MS), and 26 biopsies by histomorphology and cardiomyocytes by STimulated Emission Depletion (STED) superresolution microscopy. Notably, DIA-MS reliably detected 2273 proteins throughout each individual left-ventricular biopsy, of which 160 proteins showed significant abundance changes between AS-subtype and non-failing samples including the cardiac ryanodine receptor (RyR2). Hierarchical clustering segregated unique proteotypes that identified three hemodynamic AS-subtypes. Additionally, distinct proteotypes were linked with AS-subtype specific differences in cardiomyocyte hypertrophy. Furthermore, superresolution microscopy of immunolabeled biopsy sections showed subcellular RyR2-cluster fragmentation and disruption of the functionally important association with transverse tubules, which occurred specifically in patients with systolic dysfunction and may hence contribute to depressed left-ventricular function in AS.

RESUMO

BACKGROUND: A majority of recurrent pregnancy loss cases (RPL) remains unexplained. We hypothesized that complications in vascular and metabolic status may guide towards underlying problems that also predispose to RPL and that the number of pregnancy losses is related. METHODS: A retrospective study in 123 women with either a history of low-order RPL (2-3 pregnancy losses) or high-order RPL (≥ 4 pregnancy losses) and 20 women with a history of uncomplicated pregnancy (controls) was performed. Vascular status was assessed by measuring hemodynamic parameters, determining abnormal parameters and analyzing their contribution to the circulatory risk profile (CRP). In a similar way, metabolic status was assessed. Metabolic parameters were measured, used to determine abnormal parameters and analyzed for their contribution to the metabolic syndrome (MetS). RESULTS: No major differences were observed in vascular or metabolic parameters between women with RPL and controls. There was no relation with the number of pregnancy losses. However, when analyzing the presence of abnormal constituents, more than 80% of women with RPL had at least one abnormal constituent of the CRP. While only 27% had one or more abnormal constituent of the MetS. CONCLUSIONS: The presence of abnormal circulatory factors prior to pregnancy, and to lesser extent constituents of the metabolic syndrome, may predispose to RPL and offer new insights to its pathophysiology.

RESUMO

OBJECTIVE: To improve the timely diagnosis and treatment of sepsis many institutions implemented automated sepsis alerts. Poor specificity, time delays, and a lack of actionable information lead to limited adoption by bedside clinicians and no change in practice or clinical outcomes. We aimed to compare sepsis care compliance before and after a multi-year implementation of a sepsis surveillance coupled with decision support in a tertiary care center. DESIGN: Single center before and after study. SETTING: Large academic Medical Intensive Care Unit (MICU) and Emergency Department (ED). POPULATION: Patients 18 years of age or older admitted to *** Hospital MICU and ED from 09/4/2011 to 05/01/2018 with severe sepsis or septic shock. INTERVENTIONS: Electronic medical record-based sepsis surveillance system augmented by clinical decision support and completion feedback. MEASUREMENTS AND MAIN RESULTS: There were 1950 patients admitted to the MICU with the diagnosis of severe sepsis or septic shock during the study period. The baseline characteristics were similar before (N = 854) and after (N = 1096) implementation of sepsis surveillance. The performance of the alert was modest with a sensitivity of 79.9%, specificity of 76.9%, positive predictive value (PPV) 27.9%, and negative predictive value (NPV) 97.2%. There were 3424 unique alerts and 1131 confirmed sepsis patients after the sniffer implementation. During the study period average care bundle compliance was higher; however after taking into account improvements in compliance leading up to the intervention, there was no association between intervention and improved care bundle compliance (Odds ratio: 1.16; 95% CI: 0.71 to 1.89; p-value 0.554). Similarly, the intervention was not associated with improvement in hospital mortality (Odds ratio: 1.55; 95% CI: 0.95 to 2.52; p-value: 0.078). CONCLUSIONS: A sepsis surveillance system incorporating decision support or completion feedback was not associated with improved sepsis care and patient outcomes.

RESUMO

PURPOSE: Although A1 pulley release is an effective treatment to reduce pain and improve hand function, complications may occur. More insight into risk factors for complications is essential to improve patient counseling and potentially target modifiable risk factors. This study aimed to identify factors associated with complications following A1 pulley release. METHODS: Patients completed baseline questionnaires, including patient characteristics, clinical characteristics, and the Michigan Hand outcomes Questionnaire. We retrospectively reviewed medical records to identify complications classified using the International Consortium for Health Outcome Measurement Complications in Hand and Wrist conditions tool. Grade 1 complications comprise treatment with additional hand therapy, splinting, or analgesics, grade 2 treatment with antibiotics or steroid injections, grade 3A minor surgical treatment, grade 3B major surgical treatment, and grade 3C complex regional pain syndrome. Logistic regression analyses were performed to examine the contribution of patient characteristics, clinical characteristics, and patient-reported outcome measurement scores to complications. RESULTS: Of the included 3,428 patients, 16% incurred a complication. The majority comprised milder grades 1 (6%) and 2 (7%) complications, followed by more severe grades 3B (2%), 3C (0.1%), and 3A (0.1%) complications. A longer symptom duration (standardized odds ratio [SOR], 1.09), ≥3 preoperative steroid injections (SOR, 3.22), a steroid injection within 3 months before surgery (SOR, 2.02), and treatment of the dominant hand (SOR, 1.34), index finger (SOR, 1.65), and middle finger (SOR, 2.01) were associated with a higher complication rate. CONCLUSION: This study demonstrates that ≥3 preoperative steroid injections and a steroid injection within 3 months before surgery were the most influential factors contributing to complications. These findings can assist clinicians during patient counseling and may guide preoperative treatment. We recommend that clinicians should consider avoiding steroid injections within 3 months before surgery and to be reluctant to perform >2 steroid injections. TYPE OF STUDY/LEVEL OF EVIDENCE: Prognostic II.

RESUMO

OBJECTIVE: To investigate the clinicopathological features and prognostic characteristics of papillary renal cell carcinoma (pRCC). METHODS: The clinical data of 114 patients with pRCC, including 91 males and 23 females, admitted to the Department of Urology, Peking University Third Hospital from May 2012 to May 2021 were retrospectively analyzed. All the cases were operated patients with clear pathological diagnosis and complete follow-up data. The log-rank test was used to analyze the relationship between the patients' clinicopathological characteristics and survival time, the Kaplan-Meier method to draw survival curves, and the Cox regression model for univariate and multifactorial analysis. RESULTS: The mean age of the 114 patients was (57.3±12.6) years. The tumors were located in the left kidney in 49 cases and in the right kidney in 65 cases. In the study, 48 radical nephrectomies and 66 partial nephrectomies were performed, 42 cases were type 1 and 72 cases were type 2, and the mean maximum tumor diameter was (5.5±3.6) cm. pT1a stage 52 cases, pT1b stage 22 cases, pT2 stage 4 cases, pT3 stage 33 cases, and pT4 stage 3 cases were staged. According to the World Health Organization / International Society of Urological Pathology (WHO/ISUP), there were 13 cases of gradeⅠ, 44 cases of grade Ⅱ, 51 cases of grade Ⅲ, and 6 cases of grade Ⅳ. And 34 of the 114 patients had vascular cancer embolism, 30 cases had lymph node metastasis, and 3 cases had adrenal metastasis. The median follow-up time after surgery was 22 months, and the 3-year progression-free survival rate was 95.6%. The patients with type 1 and type 2 pRCC showed statistically significant differences in age (P=0.046), body mass index (P=0.008), surgical approach (P=0.001), maximum tumor diameter (P < 0.001), vascular cancer embolism (P < 0.001), lymph node metastasis (P < 0.001), pT stage (P < 0.001), and nuclear grade (P < 0.001). The 3-year progression-free survival rates for type 1 and type 2 pRCC were 100% and 69.4%, respectively, with type 1 having a significantly better prognosis than with type 2 (P=0.003). Univariate analysis of the patients with type 2 pRCC showed that pT stage (P < 0.001), vascular cancer embolism (P < 0.001) and lymph node metastasis (P < 0.001) were strongly associated with their prognosis. Multifactorial analysis showed that vascular cancer embolism was an independent prognostic factor for progression-free survival in type 2 pRCC (P=0.001). Univariate analysis of the pRCC patients undergoing radical nephrectomy showed that pT stage (P=0.006), vascular cancer embolism (P=0.001), and lymph node metastasis (P=0.008) were significant factors affecting their prognosis, and further multifactorial analysis showed that only vascular cancer embolism was an indepen-dent prognostic factor for their progression-free survival (P=0.006). CONCLUSION: Type 2 pRCC has more morbidity, more lymph node metastases, more advanced pT stage, and higher pathologic grading than type 1 pRCC. The presence of vascular cancer embolism is an independent prognostic factor in patients with type 2 pRCC and pRCC undergoing radical nephrectomy.

RESUMO

EXECUTIVE SUMMARY: We sought to determine emergency medicine physicians' accuracy in designating patients' disposition status as "inpatient" or "observation" at the time of hospital admission in the context of Medicare's Two-Midnight rule and to identify characteristics that may improve the providers' predictions. We conducted a 90-day observational study of emergency department (ED) admissions involving adults aged 65 years and older and assessed the accuracy of physicians' disposition decisions. Logistic regression models were fit to explore associations and predictors of disposition. A total of 2,257 patients 65 and older were admitted through the ED. The overall error rate in physician designation of observation or inpatient was 36%. Diagnoses most strongly associated with stays lasting less than two midnights included diverticulitis, syncope, and nonspecific chest pain. Diagnoses most strongly associated with stays lasting two or more midnights included orthopedic fractures, biliary tract disease, and back pain. ED physicians inaccurately predicted patient length of stay in more than one third of all patients. Under the Two-Midnight rule, these inaccurate predictions place hospitals at risk of underpayment and patients at risk of significant financial liability. Further work is needed to increase providers' awareness of the financial repercussions of their admission designations and to identify interventions that can improve prediction accuracy.

RESUMO

Conventionally, reading and writing of data holograms utilizes a fraction of the light power because of a trade off in write and read efficiencies. This system constraint can be mitigated by applying a resonator cavity. Cavities enable more efficient use of the available light leading to enhanced read and write data rates with no additional energy cost. This enhancement is inversely related to diffraction efficiency, so these techniques work well for large capacity holographic data storage having low diffraction efficiency. The enhancement in write data transfer rate is evaluated by writing plane wave holograms and image bearing holograms in Fe:LiNbO3 with a 532 nm wavelength laser. We confirmed 1.2 times enhancement in write data rate, out of a 1.4 theoretical maximum for materials absorption of 16%.

RESUMO

Resonant optical cavities have been demonstrated to improve energy efficiencies in Holographic Data Storage Systems (HDSS). The orthogonal reference beams supported as cavity eigenmodes can provide another multiplexing degree of freedom to push storage densities toward the limit of 3D optical data storage. While keeping the increased energy efficiency of a cavity enhanced reference arm, image bearing holograms are multiplexed by orthogonal phase code multiplexing via Hermite-Gaussian eigenmodes in a Fe:LiNbO3 medium with a 532 nm laser at two Bragg angles. We experimentally confirmed write rates are enhanced by an average factor of 1.1, and page crosstalk is about 2.5%. This hybrid multiplexing opens up a pathway to increase storage density while minimizing modification of current angular multiplexing HDSS.

RESUMO

Emergency departments (EDs) are at high risk for medical errors. Checklist implementation programs have been associated with improved patient outcomes in other high-risk clinical settings and when used to address specific aspects of ED care. The aim of this study was to develop an ED Safety Checklist with broad applicability across different international ED settings. A three-round modified Delphi consensus process was conducted with a multidisciplinary and multinational panel of experts in emergency medicine and patient safety. Initial checklist items were identified through a systematic review of the literature. Each item was evaluated for inclusion in the final checklist during two rounds of web-based surveys and an online consensus meeting. Agreement for inclusion was defined a priori with a threshold of 80% combined agreement. Eighty panel members from 34 countries across all seven world regions participated in the study, with comparable representation from low- and middle-income and high-income countries. The final checklist contains 86 items divided into: (1) a general ED Safety Checklist focused on diagnostic evaluation, patient reassessment, and disposition and (2) five domain-specific ED Safety Checklists focused on handoff, invasive procedures, triage, treatment prescription, and treatment administration. The checklist includes key clinical tasks to prevent medical errors, as well as items to improve communication among ED team members and with patients and their families. This novel ED Safety Checklist defines the essential elements of high-quality ED care and has the potential to ensure their consistent implementation worldwide.

RESUMO

The aim of the study is to assess whether indocyanine green (ICG) fluorescence can replace technetium in the preoperative detection of sentinel lymph nodes (SLN) from cutaneous melanoma. The current golden standard for SLN detection is the radioisotope technetium. A promising alternative is fluorescence imaging (FLI) using ICG. In this study, we enrolled patients undergoing sentinel lymph node biopsy (SLNB) for skin melanoma at the Erasmus Medical Center between November 2022 and July 2023. The SLNB procedure was performed as a standard of care. After general anesthesia, ICG was injected intradermally around the primary tumor site. Both the patient and the surgeon were not blinded for the location of the SLN. FLI was performed before incision, in vivo after incision, and ex vivo. Fluorescent SLNs were confirmed using the gamma probe in all cases. Thirty-two patients were included in this study, and a total of 39 SLNs were harvested. The transcutaneous detection rate of ICG was 21.9%. The combined ex vivo ICG fluorescence and technetium uptake was 94.9%. One SLN contained only ICG (2.6%) and one SLN contained only technetium-uptake (2.6%). FLI using ICG resulted in a relatively low transcutaneous detection, which means that exclusive use of this technique in its present form is not feasible. However, we did find a high accumulation of ICG in the SLN, indicating the potential of ICG in combination with other imaging techniques.

RESUMO

Aims: Patients with severe aortic stenosis (AS), low transvalvular flow (LF) and low gradient (LG) with normal ejection fraction (EF)-are referred to as paradoxical LF-LG AS (PLF-LG). PLF-LG patients develop more advanced heart failure symptoms and have a worse prognosis than patients with normal EF and high-gradient AS (NEF-HG). Despite its clinical relevance, the mechanisms underlying PLF-LG are still poorly understood. Methods: Left ventricular (LV) myocardial biopsies of PLF-LG (n = 5) and NEF-HG patients (n = 6), obtained during transcatheter aortic valve implantation, were analyzed by LC-MS/MS after sequential extraction of cellular and extracellular matrix (ECM) proteins using a three-step extraction method. Proteomic data are available via ProteomeXchange with identifier PXD055391. Results: 73 cellular proteins were differentially abundant between the 2 groups. Among these, a network of proteins related to muscle contraction and arrhythmogenic cardiomyopathy (e.g., cTnI, FKBP1A and CACNA2D1) was found in PLF-LG. Extracellularly, upregulated proteins in PLF-LG were related to ATP synthesis and oxidative phosphorylation (e.g., ATP5PF, COX5B and UQCRB). Interestingly, we observed a 1.3-fold increase in cyclophilin A (CyPA), proinflammatory cytokine, in the extracellular extracts of PLF-LG AS patients (p < 0.05). Consistently, immunohistochemical analysis confirmed its extracellular localization in PLF-LG AS LV sections along with an increase in its receptor, CD147, compared to the NEF-HG AS patients. Levels of core ECM proteins, namely collagens and proteoglycans, were comparable between groups. Conclusion: Our study pinpointed novel candidates and processes with potential relevance in the pathophysiology of PLF-LG. The role of CyPA in particular warrants further investigation.

RESUMO

BACKGROUND: Cardiac fibrosis plays a major pathophysiological role in any form of chronic heart disease, and high levels are associated with poor outcome. Diffuse and focal cardiac fibrosis are different subtypes, which have different pathomechanisms and prognostic implications. The total fibrosis burden in endomyocardial biopsy tissue was recently proved to play an independent prognostic role in aortic stenosis patients after transcatheter aortic valve implantation (TAVI). AIMS: Here, for the first time, we aim to assess the specific impact of different fibrosis subtypes on sudden cardiac death (SCD) as a primary reason for cardiovascular mortality after TAVI. METHODS: The fibrosis pattern was assessed histologically in the left ventricular biopsies obtained during TAVI interventions in 161 patients, who received a structured follow-up thereafter. RESULTS: Receiver operating characteristic analyses, performed 6, 12, 24 and 48 months after TAVI, showed diffuse, but not focal, fibrosis as a significant predictor for SCD at all timepoints, with the highest area under the curve at the first time point and a decrease in its SCD predictivity over time. In both multivariate Cox proportional hazards and Fine-Gray competing risk models, including both fibrosis subtypes, as well as age, sex and ejection fraction, high diffuse fibrosis remained statistically significant. Accordingly, it represents an independent SCD predictor, most importantly for the occurrence of early events. CONCLUSIONS: The burden of diffuse cardiac fibrosis plays an important and independent prognostic role regarding SCD early after TAVI. Therefore, the histological evaluation of fibrosis topography has value as a prognostic tool for TAVI patients and may help to tailor individualised approaches to optimise their postinterventional management.

RESUMO

BACKGROUND: Existing evidence suggests a relation between cardiovascular dysfunction and diminished ovarian reserve. While it is known that pre-existent cardiovascular dysfunction is also associated with the development of preeclampsia (PE) during pregnancy, we hypothesize that signs of diminished ovarian reserve may occur more frequently among women with a history of hypertensive disorders of pregnancy (HDP). The aim of our study was therefore to analyse if women with a history of HDP show signs of diminished ovarian reserve, represented by lower anti-Mullarian hormone (AMH) levels, compared to controls. For this retrospective observational case control study, patients included women with a history of HDP, whereas controls constituted of women with a history of an uncomplicated pregnancy. The study was conducted in a tertiary referral centre in which all women underwent a one-time cardiovascular and metabolic assessment. Ovarian reserve and markers of cardiovascular function were evaluated, adjusted for age and body mass index (BMI) using linear regression analyses. RESULTS: 163 patients and 81 controls were included over a time span of 3 years. No signs of diminished ovarian reserve i.e. lower AMH level were observed in the patient group versus controls. A subgroup analysis even showed higher AMH levels in late onset HDP as compared to controls (2.8 vs. 2.0 µg/L, p = 0.025). As expected, cardiovascular function markers were significantly less favourable in the patient group compared to controls; higher levels of systolic blood pressure (BP) (5%), diastolic BP (4%), triglycerides (29%), glucose (4%) and insulin levels (81%) (all p < 0.05), whereas high density lipid (HDL) cholesterol was 12% lower (NS). CONCLUSIONS: Despite unfavourable cardiovascular risk profile, the present study does not substantiate the hypothesis that women with HDP show accelerated ovarian ageing as compared to healthy parous controls. Although HDP patients should be warned about their cardiovascular health, they shouldn't be concerned about unfavourable ovarian reserve status.

RESUMO

BACKGROUND: Accurate risk stratification is important to improve patient selection and outcome of patients with severe aortic stenosis (AS) undergoing transcatheter aortic valve replacement (TAVR). As epicardial adipose tissue (EAT) is discussed to be involved in cardiovascular disease, it could be useful as a marker of poor prognosis in patients with severe AS undergoing TAVR. METHODS: A total of 416 patients diagnosed with severe AS by transthoracic echocardiography were assigned for TAVR and enrolled for systematic assessment. Patients underwent clinical surveys and 5-year long-term follow-up, with all-cause mortality as the primary endpoint. EAT volume was quantified on pre-TAVR planning CTs. Patients were retrospectively dichotomized at the median of 74 cm3 of EAT into groups with low EAT and high EAT volumes. Mortality rates were compared using Kaplan-Meyer plots and uni- and multivariable cox regression analyses. RESULTS: A total number of 341 of 416 patients (median age 80.9 years, 45% female) were included in the final analysis. Patients with high EAT volumes had similar short-term outcome (p = 0.794) but significantly worse long-term prognosis (p = 0.023) compared to patients with low EAT volumes. Increased EAT volumes were associated with worse long-term outcome (HR1.59; p = 0.031) independently from concomitant cardiovascular risk factors, general type of AS, and functional echocardiography parameters of AS severity (HR1.69; p = 0.013). CONCLUSION: Increased EAT volume is an independent predictor of all-cause mortality in patients with severe AS undergoing TAVR. It can be easily obtained from pre-TAVR planning CTs and may thus qualify as a novel marker to improve prognostication and management of patient with severe AS.

RESUMO

OBJECTIVE: To gain insight into the considerations of breast cancer survivors to return or not for embryo transfer after the use of fertility preservation. STUDY DESIGN: This is a qualitative study with semi-structured interviews. The interviews were planned until saturation of themes had been achieved. Content analysis was used to analyze the data. Sixteen out of 35 approached women took part in this study. Interviews were conducted with women who had oocytes or embryos cryopreserved prior to breast cancer treatment at the Maastricht University Medical Center between 2008 and 2016. All women who had cryopreservation more than two years ago were invited for the interviews. Women who had recurrence of disease were excluded. In the interviews we hypothesized the situation 'suppose the menses would have been recovered completely' for women who still had chemotherapy-induced menopause or used an GnRH (Gonadotropin-releasing hormone) analogue. RESULTS: Most women had a strong intrinsic motivation to pursue natural conception over the use of earlier cryopreserved oocytes or embryos. Time pressure was the most mentioned consideration to use cryopreserved oocytes or embryos. The wish to use pre-implantation genetic testing (PGT) in the presence of a germline BRCA1/2 mutation was another consideration to opt for embryo transfer. Furthermore, the physician's advice was an important motivation to choose for either natural conception or the use of cryopreserved oocytes or embryos. CONCLUSION: Multiple considerations influence women's decision making on the mode of conception after breast cancer. Although it concerned a single-center study in a highly-selected population, insight into these considerations can help physicians to address these important topics in counseling these women.

RESUMO

BACKGROUND: Oral and laryngeal squamous cell carcinoma (OSCC and LSCC) and papillary thyroid carcinoma (PTC) are common head and neck cancers (HNCs) typically treated surgically. Challenges in tumour delineation often lead to inadequate resection margins in OSCC and LSCC, and missed multifocality in PTC. Fluorescence imaging (FLI) using near-infrared tumour-targeting tracers may improve intraoperative identification of malignancy, facilitating precise excision. This study evaluates six potential FLI targets in OSCC, LSCC and PTC. MATERIALS AND METHODS: Immunohistochemical staining was performed on OSCC (n = 20), LSCC (n = 10) and PTC (n = 10), assessing CEA, c-Met, EpCAM, EGFR, integrin αvß6 and VEGF-α. Expression was scored (0-12) using the total immunostaining score (TIS) system, and categorized into absent (TIS 0), low (TIS 1-5), moderate (TIS 6-8) or high (TIS 9-12). RESULTS: Integrin αvß6 showed significant overexpression in OSCC (TIS: 12; p < 0.001) and LSCC (TIS: 8; p = 0.002), with 80% of OSCC and 90% of LSCC exhibiting moderate-high expression. Similarly, EGFR expression was moderate-high in most OSCC (87.5%; TIS: 8) and universally high in LSCC (100%; TIS: 12). In PTC, EGFR and VEGF-α expressions were low-moderate, but significantly higher than in healthy tissue (TIS: 6; p < 0.006). CONCLUSION: This study highlights integrin αvß6 and EGFR as viable FLI targets in OSCC and LSCC, especially integrin αvß6 for tumour margin delineation. In PTC, despite lower expressions, the significant overexpression of VEGF-α, c-MET, and EGFR suggests their potential as FLI targets. Our findings support the development of tumour-targeted FLI tracers to improve surgical precision in HNC.

RESUMO

Tomato plants exhibiting typical symptoms of begomovirus infection, including leaf deformation, curling, and yellowing, were collected from cultivated fields in Lavalle Department, Corrientes, Argentina, in 2010. Although the number of affected plants was only 2% within a farm, the finding is of considerable importance since the white fly Bemisia tabaci is widely spread within the country, even in other southernmost areas such as the cinturón hortícola de Buenos Aires (horticultural belt around Buenos Aires). DNA isolated from infected tomato leaves collected from three symptomatic tomato plants was amplified by PCR with specific primers designed to amplify a region of component A and B of the Begomovirus genome (3). The amplified DNA fragment was sequenced and a new set of primers were designed based on the obtained sequences. A DNA fragment of about 1,300 bp was amplified and later the complete genome, which was 2,683 bp long. No fragments were obtained when template DNA was from non-infected leaf samples. The 2,683-bp fragment was annotated at the NCBI under Accession No. KC132844. Analysis by NCBI BLAST showed that it was highly homologous to DNA-A component of Begomovirus. Furthermore, the genome organization was typical of DNA-A component of bipartite New World begomovirus. The sequence had one open reading frame (ORF) on the viral-sense strand (AV1/CP) and four ORFs on the complementary-sense strand (AC1/Rep, AC2/TrAp, AC3/REn, and AC4). In order to confirm this finding, the viral genome was amplified by rolling circle amplification (RCA, TempliPhi 100 Amplification Kit, Amersham Biosciences) as described by the manufacturer instructions. The RCA full-length product was digested with XhoI generating a 2,700-bp DNA fragment, suggesting the presence of only one restriction site, in agreement with the bioinformatics analysis of the KC132844 sequence. This PCR product was used as template in PCR reactions with specific primers to DNA-A or DNA-B components. While the DNA-A primers generated the expected 1,300-bp fragment, those homologous to the DNA-B component did not generate amplifications. These results confirmed the identity of the DNA-A component of the isolate MT8. The full sequence of the DNA-A component was 94% homologous to the DNA-A sequence of the Uruguayan begomovirus Tomato Rugose Yellow Leaf Curl Virus-[U4.1] (JN381823.1). Therefore, considering our results and the criteria proposed by Fauquet (1), isolate MT8 is a new species of begomovirus described recently (2). This is the first report of TRYLCV in one of the main areas of tomato production in Argentina. This virus might be accompanying another begomovirus TYVSV that provoked yellow veins symptoms in tomato plants cultivated in the same area of Corrientes. These viruses appeared recently and concomitantly with the introduction of the white fly Bemisia spp. in the area, which is one of the main production areas of tomato and provides fresh tomatoes to the whole country, and in wintertime to the city of Buenos Aires, when the horticultural belt around Buenos Aires is not under production.

RESUMO

Recent studies have documented the disparate impact of the COVID-19 pandemic on labor market outcomes for different racial groups. This paper adds to this literature by documenting that the employment of Asian Americans-in particular those with no college education-has been especially hard hit by the economic crisis associated with the onset of the pandemic. This can only partly be explained by differences in demographics, local market conditions, and job characteristics, and it also cannot be entirely explained by possible different selection into education levels across ethnic groups. The burden on Asian Americans is primarily borne by those who are not US-born. Supplementary Information: The online version contains supplementary material available at 10.1007/s00181-022-02306-5.
