ABSTRACT

OBJECTIVES: To evaluate the prognostic and locoregional metastatic features of carcinoma ex pleomorphic adenoma of submandibular gland (SMG-CXPA) and improve the understanding of this uncommon condition.

PATIENTS AND METHODS: We retrospectively reviewed patients who were diagnosed with SMG-CXPA. The survival data of SMG-CXPA patients were statistically analyzed using Cox regression and Kaplan-Meier method. The associations between cervical metastasis and clinicopathological parameters were evaluated using chi-squared test. Additionally, two different histological categories (histological grade and invasiveness) and their combination were evaluated with the Kaplan-Meier method and receiver operating characteristic curves.

RESULTS: In total, 86 patients were diagnosed: 38 clinically node-negative, 31 pathologically node-negative and 17 node-positive patients. Clinical tumor stage and histological grade were two independent prognostic factors for SMG-CXPA. There were significant correlations between sex, tumor size, clinical tumor stage, clinical lymph node stage, histological grade, invasiveness, malignant components, perineural invasion and no specific criteria exist for the clinical outcome.

CONCLUSION: SMG-CXPA is a high-grade malignancy with an unfavorable prognosis. Elective neck dissection should be performed in SMG-CXPA patients with a risk of locoregional metastasis. Histological grade seems to be a more valuable predictor of lymph node involvement than invasiveness.

ABSTRACT

Cardiotoxicity is a serious adverse effect of an anticancer drug, doxorubicin (DOX), which can occur within a year or decades after completion of therapy. The present study was designed to address a knowledge gap concerning a lack of circulating biomarkers capable of predicting the risk of cardiotoxicity induced by DOX. Profiling of 2083 microRNAs (miRNAs) in mouse plasma revealed 81 differentially expressed miRNAs one week after 6, 9, 12, 18, or 24 mg/kg total cumulative DOX doses (early-onset model) or saline (SAL). Among these, the expression of 7 miRNAs were altered prior to the onset of myocardial injury at 12 mg/kg and higher cumulative doses. The expression of only miR-34a-5p was significantly (FDR<0.1) elevated at all total cumulative doses compared to concurrent SAL-treated controls and showed a statistically significant dose-related response. The trend in plasma miR-34a-5p expression levels during DOX exposures also correlated with a significant dose-related increase in cardiac expression of miR-34a-5p in these mice. Administration of a cardioprotective drug, dexrazoxane, to mice before DOX treatment, significantly mitigated miR-34a-5p expression in both plasma and heart in conjunction with attenuation of cardiac pathology. This association between plasma and heart may suggest miR-34a-5p as a potential early circulating marker of early-onset DOX cardiotoxicity. In addition, higher expression of miR-34a-5p (FDR<0.1) in plasma and heart compared to SAL-treated controls 24 weeks after 24 mg/kg total cumulative DOX dose, when cardiac function was altered in our recently established delayed-onset cardiotoxicity model, indicated its potential as an early biomarker of delayed-onset cardiotoxicity.

ABSTRACT

BACKGROUND: Polycystic ovary syndrome (PCOS) is one of the most prevalent endocrine disorders in females of reproductive age, with a prevalence of 20%-33% in the general population. Interleukin (IL)-34 is a recently explored proinflammatory cytokine and is an important modulator in different disease types. However, the function of IL-34 in PCOS has yet to be investigated.

OBJECTIVE: The purpose of this study was to determine the IL-34 serum level in women with PCOS and to compare it to that of a relatively healthy control group. Focusing on its relationship with IL-6, TNF-α, and IL-1β and homeostatic model assessment for insulin resistance (HOMA-IR), triglyceride, and low-density lipoprotein cholesterol (LDL-C).

MATERIALS AND METHODS: In this study, blood samples were obtained from 100 women with PCOS and 100 healthy control women for the purpose of estimating their serum levels of IL-34, IL-6, TNF-α, and IL-1β using the enzyme-linked immunosorbent assay technique.

RESULTS: Serum levels of IL-34, IL-6, TNF-α, and IL-1β were all higher in PCOS women than in healthy controls, and the difference was highly statistically significant. Serum IL-34 concentration was positively correlated with IL-6, TNF-α, and IL-1β concentration. Additionally, serum concentrations of IL-34 were positively correlated with HOMA-IR, triglyceride, and LDL-C.

CONCLUSION: When compared to normal women, IL-34, IL-6, TNF-α, and IL-1β levels were highly statistically significant in PCOS, and these high levels were associated with other cytokines (IL-6, TNF-α, and IL-1β), HOMA-IR, triglyceride, and LDL-C.

ABSTRACT

Recharge from preferential flow through mega-thick (100-1,000 m) unsaturated zones is a pervasive phenomenon, as demonstrated with a case study of volcanic highland recharge areas in the Great Basin province in southern Nevada, USA. Statistically significant rising water-level trends occur for most study-area wells and resulted from a relatively wet period (1969-2005) in south-central Nevada. Wet and dry winters control water-level trends, with water levels rising within a few months to a year following a wet-winter recharge event and declining during sustained dry periods. Even though a megadrought has persisted since 2000, this drought condition did not preclude major recharge events. Modern groundwater reaching the water table is consistent with previous geochemical studies of the study area that indicate mixing of modern and late Pleistocene recharge water. First-order approximations and simple mixing models of modern and late Pleistocene water indicate that 10 to 40 percent of recharge is preferential flow and that modern recharge may play a larger role in the water budget than previously thought.

ABSTRACT

PURPOSE: To assess the prevalence and related factors of a newly developed insomnia disorder following craniotomy for brain tumor resection. Furthermore, we examined the association of pre- and postoperative insomnia with the 2-year mortality rate.

METHODS: The South Korean national registration cohort database was used as the data source. This study includes all adult patients who underwent craniotomy for brain tumor resection from January 1, 2011, to December 31, 2017. G47.0 and F51.0 (International Statistical Classification of Diseases and Related Health Problems 10th Revision codes) were used to identify insomnia disorders.

RESULTS: In total, 4,851 patients were included. Among them, 913 (18.8%) and 447 (9.2%) patients were assigned to the preoperative and postoperative insomnia groups, respectively. After modeling using multivariable logistic regression, older age (odds ratio (OR) 1.02, 95% confidence interval (CI) 1.01-1.03; P < 0.001), reoperation within 1 year (OR 2.12, 95% CI 1.47-3.06; P < 0.001), and newly acquired brain disability (OR 1.32, 95% CI 1.01-1.71; P = 0.043) were associated with an increased prevalence of newly developed postoperative insomnia disorder. After modeling using multivariable Cox regression, the preoperative and postoperative insomnia disorder groups showed a 1.17-fold (hazard ratio (HR) 1.17, 95% CI 1.02-1.34; P = 0.021) and a 1.85-fold (HR 1.85, 95% CI 1.59-2.15, P < 0.001) increased 2-year all-cause mortality risk compared to the control group, respectively.

CONCLUSION: In South Korea, 9.2% of the patients with brain tumors were newly diagnosed with an insomnia disorder following craniotomy for brain tumor resection, which was associated with an increased risk of 2-year mortality.

ABSTRACT

INTRODUCTION: The evidence base for parenteral nutrition (PN) in advanced cancer patients is limited. We studied healthcare providers’ (HCPs’) experiences with PN in cancer patients, focusing on perceived treatment benefits and challenges.

METHODS: An 18-item online survey was emailed to HCPs attending one of three regional palliative care seminars held within a 6-month period. The survey included single-response items, multiple-response items, and free text boxes concerning PN. Descriptive statistics and qualitative thematic content analysis were applied.

RESULTS: One hundred and two seminar participants completed the survey. Ninety-three percent were female, 86% were nurses/oncological nurses, and 80% worked in primary care. Respondents reported a well-functioning collaboration across levels of care. They perceived that PN may increase the patients’ level of energy, improve the general condition, and reduce eating-related distress. On the downside, HCPs observed burdensome side effects, that the treatment was resource-demanding, and that decisions on PN withdrawal were difficult.

CONCLUSION: The study results are based on the perspectives of more than 100 HCPs with comprehensive clinical experience with PN. Their knowledge represents an important experience base for improvement of healthcare services and advanced care planning.

ABSTRACT

In this prospective study, we postulate that there is a difference between clearance of [99mTc]Tc- ethyl cysteinate dimer (ECD) in the seizure onset zone (SOZ) and other brain areas and thus SOZ localization by clearance patterns might become a potential novel method for SOZ localization in epilepsy. The parametric images of brain ECD clearance were generated by linear regression model analysis from serial brain SPECT scans from 30 to 240 min after ECD injection (7-times point) in 7 patients with drug-resistant epilepsy and 3 normal volunteers. Clearance patterns of the SOZ confirmed by good surgical outcome or consensus with other investigations were analyzed quantitatively and semi-quantitatively by visual grading (slower or faster washout than contralateral brain regions). The average [^99mTc]Tc-ECD clearance rates of SOZs were + 1.08% ± 2.57%/hr (wash in), -7.02% ± 2.56%/hr (washout), and -5.37% ± 1.71%/hr (washout) in ictal, aura and interictal states, respectively. Paired t-tests between the SOZ and contralateral regions showed statistically significant difference (p = 0.039 in interictal state). Clearance patterns that can define the SOZs were 1) wash in and slow washout on ictal slope, 2) fast washout on aura slope and interictal slope with 100% (6/6), 100% (2/2) and 75% (6/8) localization using ictal, aura, and interictal slope maps, respectively. Our study provided the evidence that clearance pattern methods are potential additive diagnostic tools for SOZ localization when routine one-time point SPECT are unable to define the SOZ.

ABSTRACT

OBJECTIVE: To determine the extent to which Black race is associated with the infant mortality rate (< 365 day, IMR) of births to US-born and foreign-born Latinx women.

METHODS: Stratified and multivariable binominal log-linear regression analyses were performed on the 2010-2013 National Center for Health Statistics linked birth-death certificate files of singleton infants.

RESULTS: The IMR of births to US-born Black Latinx women (N = 54,542) exceeded that of births to US-born White Latinx women (N = 1,320,084): 5.7/1000 vs 4.2/1000, RR = 1.4 (1.2, 1.5). In contrast, the IMR of births to foreign-born Black Latinx women (N = 35,544) approximated that of births to foreign-born White Latinx women (N = 1,372,172): 3.8/1000 vs 3.6/1000, RR = 1.0 (0.9, 1.2) The adjusted (controlling for maternal age, education, prenatal care, high parity, and region of residence) RR of infant mortality for births to US-born and foreign-born Black (versus non-Latinx White) Latinx women equaled 1.4 (1.2, 1.6) and 1.0 (0.8, 1.2), respectively. The adjusted RR of infant mortality for births to US-born and foreign-born White (versus non-Latinx White) Latinx women equaled 1.0 (0.9, 1.0) and 0.8 (0.7, 0.8), respectively.

CONCLUSIONS: Black race is associated with a 1.4-fold higher IMR among births to US-born Latinx women. A similar phenomenon does not occur among foreign-born Latinx women. These intriguing findings highlight that the social construct of Black race across the life-course of Latinx women are detrimental to infant outcome.

ABSTRACT

According to the definition that the European Commission (2001) offered us, corporate social responsibility is a set of measures that an organization can adapt, to improve the well-being of its stakeholders and promote the balance of economic, social, and environmental performance. The stakeholder theory clarifies that this decision-making must take into consideration all groups of people, being the only way of having a proportional benefit. Based on this premise, in this study, we intend to unravel the main determinants of corporate social responsibility in 63 Portuguese companies. To accomplish that, we used panel data, withdrawn from the SABI database, in the period comprehended between 2008 and 2018, applying the Probit model and the dynamic GMM for robustness check. The sample is composed of 42 companies that find themselves listed in the Portuguese stock exchange and 21 that do not. We can verify that the outcomes allow the analyses of nine variables, among them, only the audit, the asset rotation ratio, the debt ratio, the size, age, and financial autonomy show themselves as statistically positive in the implementation of corporate social responsibility practices. Even though the outcomes were not what we initially predicted, they revealed the positive impact of such practices. We consider them necessary and a reality that companies should pursue, even for the gains of capital that it might represent. We firmly believe that being socially responsible constitutes an essential practice from which all of us can benefit, contributing to life improvement in the community and for environmental sustainability.

ABSTRACT

PURPOSE: Epilepsy with centrotemporal spikes (ECTS) is the most common epilepsy syndrome in children and usually presents with cognitive dysfunctions. However, little is known about the processing speed dysfunction and the associated neuroimaging mechanism in ECTS. This study aims to investigate the brain functional abnormality of processing speed dysfunction in ECTS patients by using the ¹⁸F-fluorodeoxyglucose (¹⁸F-FDG) positron emission tomography (PET) and resting-state functional magnetic resonance imaging (rs-fMRI).

METHODS: This prospective study recruited twenty-eight ECTS patients who underwent the ¹⁸F-FDG PET, rs-fMRI, and neuropsychological examinations. Twenty children with extracranial tumors were included as PET controls, and 20 healthy children were recruited as MRI controls. The PET image analysis investigated glucose metabolism by determining standardized uptake value ratio (SUVR). The MRI image analysis explored abnormal functional connectivity (FC) within the cortical-striatal circuit through network-based statistical (NBS) analysis. Correlation analysis was performed to explore the relationship between SUVR, FC, and processing speed index (PSI).

RESULTS: Compared with healthy controls, ECTS patients showed normal intelligence quotient but significantly decreased PSI (P = 0.04). PET analysis showed significantly decreased SUVRs within bilateral caudate, putamen, pallidum, left NAc, right rostral middle frontal gyrus, and frontal pole of ECTS patients (P < 0.05). Rs-fMRI analysis showed absolute values of 20 FCs were significantly decreased in ECTS patients compared with MRI controls, which connected 16 distinct ROIs. The average SUVR of right caudate and the average of 20 FCs were positively correlated with PSI in ECTS patients (P = 0.034 and P = 0.005, respectively).

CONCLUSION: This study indicated that ECTS patients presented significantly reduced PSI, which is closely associated with decreased SUVR and FC of cortical-striatal circuit. Caudate played an important role in processing speed dysfunction.
