Background:
Heart failure (HF) in patients with type 2 diabetes mellitus (T2D) has received growing attention. We examined the effect of HF development on prognosis compared with other cardiovascular or renal diagnoses in patients with T2D.

Methods and Results:
Patients with new T2D diagnosis patients were identified between 1998 and 2015 through Danish nationwide registers. At yearly landmark timepoints after T2D diagnosis, we estimated the 5-year risks of death, 5-year risk ratios, and decrease in lifespan within 5 years associated with the development of HF, ischemic heart disease, stroke, peripheral artery disease, and chronic kidney disease. A total of 153 403 patients with newly diagnosed T2D were followed for a median of 9.7 years (interquartile range, 5.8–13.9) during which 48 087 patients died. The 5-year risk ratio of death associated with HF development 5 years after T2D diagnosis was 3 times higher (CI, 2.9–3.1) than patients free of diagnoses (CI, 2.9–3.1). Five-year risk ratios were lower for ischemic heart disease (1.3 [1.3–1.4]), stroke (2.2 [2.1–2.2]), chronic kidney disease (1.7 [1.7–1.8]), and peripheral artery disease (2.3 [2.3–2.4]). The corresponding decrease in lifespan within 5 years when compared with patients free of diagnoses (in months) was HF 11.7 (11.6–11.8), ischemic heart disease 1.6 (1.5–1.7), stroke 6.4 (6.3–6.5), chronic kidney disease 4.4 (4.3–4.6), and peripheral artery disease 6.9 (6.8–7.0). HF in combination with any other diagnosis imposed the greatest risk of death and decrease in life span compared with other combinations. Supplemental analysis led to similar results when stratified according to age, sex, and comorbidity status, and inclusion period.

Conclusions:
HF development, at any year since T2D diagnosis, was associated with the highest 5-year absolute and relative risk of death, and decrease in lifespan within 5 years, when compared with development of other cardiovascular or renal diagnoses.
Prevalence of ECGs Exceeding Thresholds for ST‐Segment–Elevation Myocardial Infarction in Apparently Healthy Individuals: The Role of Ethnicity

Background
Early prehospital recognition of critical conditions such as ST‐segment–elevation myocardial infarction (STEMI) has prognostic relevance. Current international electrocardiographic STEMI thresholds are predominantly based on individuals of Western European descent. However, because of ethnic electrocardiographic variability both in health and disease, there is a need to reevaluate diagnostic ST‐segment elevation thresholds for different populations. We hypothesized that fulfillment of ST‐segment elevation thresholds of STEMI criteria (STE‐ECGs) in apparently healthy individuals is ethnicity dependent.

Methods and Results
HELIUS (Healthy Life in an Urban Setting) is a multiethnic cohort study including 10 783 apparently healthy subjects of 6 different ethnicities (African Surinamese, Dutch, Ghanaian, Moroccan, South Asian Surinamese, and Turkish). Prevalence of STE‐ECGs across ethnicities, sexes, and age groups was assessed with respect to the 2 international STEMI thresholds: sex and age specific versus sex specific. Mean prevalence of STE‐ECGs was 2.8% to 3.4% (age/sex‐specific and sex‐specific thresholds, respectively), although with large ethnicity‐dependent variability. Prevalences in Western European Dutch were 2.3% to 3.0%, but excessively higher in young (<40 years) Ghanaian males (21.7%–27.5%) and lowest in older (≥40 years) Turkish females (0.0%). Ethnicity (sub‐Saharan African origin) and other variables (eg, younger age, male sex, high QRS voltages, or anterolateral early repolarization pattern) were positively associated with STE‐ECG occurrence, resulting in subgroups with >45% STE‐ECGs.

Conclusions
The accuracy of diagnostic tests partly relies on background prevalence in healthy individuals. In apparently healthy subjects, there is a highly variable ethnicity‐dependent prevalence of ECGs with ST‐segment elevations exceeding STEMI thresholds. This has potential consequences for STEMI evaluations in individuals who are not of Western European descent, putatively resulting in adverse outcomes with both over‐ and underdiagnosis of STEMI.

Background
Myocardial infarction is an important cause of morbidity and mortality in both men and women. Atypical or the absence of symptoms, more prevalent among women, may contribute to unrecognized myocardial infarctions and missed opportunities for preventive therapies. The aim of this research is to investigate sex‐based differences of undiagnosed myocardial infarction in the general population.

Methods and Results

In the Lifelines Cohort Study, all individuals ≥18 years with a normal baseline ECG were followed from baseline visit till first follow‐up visit (≈5 years, n=97 203). Individuals with infarct‐related changes between baseline and follow‐up ECGs were identified. The age‐ and sex‐specific incidence rates were calculated and sex‐specific cardiac symptoms and predictors of unrecognized myocardial infarction were determined. Follow‐up ECG was available after a median of 3.8 (25th and 75th percentile: 3.0–4.6) years. During follow‐up, 198 women experienced myocardial infarction (incidence rate 1.92 per 1000 persons‐years) compared with 365 men (incidence rate 3.30;
P
<0.001 versus women). In 59 (30%) women, myocardial infarction was unrecognized compared with 60 (16%) men (
P
<0.001 versus women). Individuals with unrecognized myocardial infarction less often reported specific cardiac symptoms compared with individuals with recognized myocardial infarction. Predictors of unrecognized myocardial infarction were mainly hypertension, smoking, and higher blood glucose level.

Conclusions
A substantial proportion of myocardial infarctions are unrecognized, especially in women. Opportunities for secondary preventive therapies remain underutilized if myocardial infarction is unrecognized.
Neural Correlates of Fixated Low- and High-level Scene Properties during Active Scene Viewing

Published: June 2020

Abstract
During real-world scene perception, viewers actively direct their attention through a scene in a controlled sequence of eye fixations. During each fixation, local scene properties are attended, analyzed, and interpreted. What is the relationship between fixated scene properties and neural activity in the visual cortex? Participants inspected photographs of real-world scenes in an MRI scanner while their eye movements were recorded. Fixation-related fMRI was used to measure activation as a function of lower- and higher-level scene properties at fixation, operationalized as edge density and meaning maps, respectively. We found that edge density at fixation was most associated with activation in early visual areas, whereas semantic content at fixation was most associated with activation along the ventral visual stream including core object and scene-selective areas (lateral occipital complex, parahippocampal place area, occipital place area, and retrosplenial cortex). The observed activation from semantic content was not accounted for by differences in edge density. The results are consistent with active vision models in which fixation gates detailed visual analysis for fixated scene regions, and this gating influences both lower and higher levels of scene analysis.

This study evaluates the morphological concept of Crepidotus variabilis and similar taxa based on basidiospore and cheilocystidia characters. A phylogenetic analysis of the ITS region clearly distinguished C. variabilis var. variabilis from the two other distinct taxa of the same lineage, C. variabilis var. trichocystis and C. neotrichocystis. We also recognised one additional morphologically similar and undescribed species that belongs to the C. variabilis lineage. All four taxa can also be recognised morphologically using basidiospore and cheilocystidia characters. Our detailed statistical comparison of these characters improves the knowledge of their variability and specifies more precisely the morphological circumscription of the taxa within this group.

ObjectivesTo investigate the existing published evidence supporting the role of laryngopharyngeal reflux (LPR) in the development of the select nonfunctional laryngeal diseases of laryngotracheal stenosis, granuloma, leukoplakia, and laryngeal infectionsData SourcesPubMed, Cochrane Library, and Scopus.Review MethodsA systematic review was performed by 3 independent investigators for studies providing information about the prevalence and role of LPR in the development of laryngotracheal stenosis, granuloma, leukoplakia, and laryngeal infections. Diagnostic criteria and clinical outcome evaluation of included studies were analyzed with PRISMA criteria.ResultsOf the 64 relevant publications, 27 clinical and 4 basic science studies were included. Ten studies used objective reliable examinations for LPR diagnosis (eg, dual‐ or triple‐probe or oropharyngeal pH monitoring, multichannel intraluminal impedance–pH monitoring, or pepsin detection). According to the bias analysis and the results of studies, the association between LPR and laryngotracheal stenosis, leukoplakia, laryngeal papillomatosis, or vocal fold granuloma remains poorly demonstrated. There is a notable heterogeneity among included studies regarding their inclusion criteria, diagnostic methods, and clinical outcome evaluation. Although some experimental findings support the involvement of bile salts and other gastroduodenal proteins active in alkaline pH, no included clinical studies assessed the role of nonacid and mixed reflux through multichannel intraluminal impedance–pH monitoring.ConclusionThe involvement of LPR in the development of leukoplakia, laryngotracheal stenosis, vocal fold granuloma, and laryngeal papillomatosis is currently not demonstrated. The potential relationship between LPR and these select nonfunctional laryngeal diseases must be confirmed through future clinical and experimental studies considering acid, nonacid, and mixed LPR.

Objective: The aim of the study was to check on the reliability and validity of the translated version of Nociception Coma Scale–Revised. Design: Prospective psychometric study. Setting: Rehabilitation and neurology unit in hospital. Subjects: Patients with prolonged disorders of consciousness. Interventions: None. Main measures: The original English version of the Nociception Coma Scale–Revised was translated into Chinese. The reliability and validity were undertaken by trained raters. Intraclass correlation coefficients were used to assess inter-rater reliability and test–retest reliability. Cronbach’s alpha test was used to investigate internal consistency. Spearman’s correlation was used to calculate concurrent validity. The Coma Recovery Scale–revised was used to assess the consciousness of patients. Results: Eighty-four patients were enrolled in the study. Inter-rater reliability of the Chinese version of Nociception Coma Scale–Revised was high for total scores and motor and verbal subscores and good for facial subscores. Test–retest reliability was high for total score and for all subscores. Analysis revealed a moderate internal consistency for subscores. For the concurrent validity, a strong correlation was found between the Nociception Coma Scale–Revised and the Face, Legs, Activity, Cry, and Consolability behavioral scale for all patients. A moderate correlation was found between the Nociception Coma Scale–Revised and the Coma Recovery Scale–revised scores for all patients. Conclusion: The Chinese version of Nociception Coma Scale–Revised has good reliability and validity data for assessing responses to pain in patients with prolonged disorders of consciousness.

Background We know little about the changes of brain activity in patients with normal-tension glaucoma (NTG). Purpose To investigate the altered spontaneous brain activity in patients with NTG through the resting state functional magnetic resonance imaging–fractional amplitude of low-frequency fluctuation (rsfMRI-fALFF) technique, and to explore the relationship with optical coherence tomography (OCT) and field of vision. Material and Methods Twenty patients with NTG and 20 healthy controls (HCs) (matched for sex, age, and level of education) were enrolled. Spontaneous cerebral activity variations were investigated using the rsfMRI-fALFF technique in all individuals. The average fALFF values of patients with NTG and HCs were compared. Results Compared with HCs, patients with NTG had significantly lower fALFF values in the right angular gyrus and precuneus; however, higher fALFF values in the brain regions were not observed. The values showed statistically significant negative correlation with those of the retinal nerve fiber layer (right angular gyrus: r = −0.607, P = 0.010; right precuneus: r = −0.504, P = 0.020). There was no significant correlation between the fALFF value and cup-disc ratio (right angular gyrus: r = 0.158, P = 0.494; right precuneus: r = −0.087, P = 0.706), mean deviation (right angular gyrus: r = 0.096, P = 0.468; right precuneus: r = 0.026, P = 0.845), and pattern SD value (right angular gyrus: r = 0.064, P = 0.626; right precuneus: r = −0.145, P = 0.268). Conclusion Abnormal spontaneous activities were detected in numerous brain regions of patients with NTG, which may provide useful information for understanding the dysfunction in NTG. These activity changes in brain regions may be used as effective clinical indicators for NTG.

Background: Tearing and degeneration of the rotator cuff at the tendon-to-bone junction are common in adults aged ≥50 years. Few studies have reported on the relationship between estrogen and the rotator cuff enthesis. In addition to preventing bone loss, selective estrogen receptor modulators have been shown to improve tendon and muscle quality. Purpose: To evaluate the effects of raloxifene (RLX) and vitamin D on rotator cuff tendon-to-bone healing in a rat model. Study Design: Controlled laboratory study. Methods: A total of 29 female rats (58 shoulders) were assigned to 4 groups: (1) control group, (2) ovariectomy (OVX)–only group, (3) no RLX group (OVX and rotator cuff repair [RCR]), and (4) RLX group (OVX, RCR, and RLX). Rats that did not undergo rotator cuff tear (RCT) surgery were divided into the control and OVX-only groups according to OVX surgery. Rats that underwent RCT surgery and RCR were divided into the no RLX and RLX groups according to RLX and vitamin D administration. An estrogen-deficient state was induced by OVX at 12 weeks of age. Bone mineral density (BMD) and trabecular bone characteristics were measured by micro–computed tomography, and healing of the tendon-to-bone junction was evaluated by biomechanical testing, histomorphometry, and micro–magnetic resonance imaging (MRI). Results: The mean final body weight (BW; 461.6 ± 47.3 g) of the OVX-only group was significantly higher and BMD (0.25 ± 0.07 g/cm3) was significantly lower ( P < .001) than the mean final BW (338.5 ± 35.1 g) and BMD (0.48 ± 0.05 g/cm3) of the control group. In contrast, the RLX group showed that the BW (369.6 ± 35.8 g) and BMD (0.41 ± 0.08 g/cm3) were not significantly different from the control group. The RLX group had a significantly higher histomorphometric total score (8.50 ± 1.05) than the no RLX group (4.83 ± 2.48). On biomechanical testing, the RLX group (29.7 ± 9.1 N) showed a significantly higher load to failure than the no RLX group (19.4 ± 8.8 N). On micro-MRI, the RLX group had a more homogeneous low signal and tendon continuity than the no RLX group. Conclusion: The combination treatment of RLX and vitamin D prevented a decrease in local BMD (greater tuberosity of the proximal humerus) and enhanced tendon-to-bone healing of the rotator cuff in a rat model. Clinical Relevance: This study induced an estrogen-deficient state similar to the human postmenopausal state and used drugs that are actually being prescribed in a clinical situation.

Published: June 2020

Background: The provision of end-of-life care is receiving attention locally, provincially, and nationally in Canada. It is important to ensure that interprofessional standards and competencies are in place to provide quality end-of-life care that meets the needs of patients and their families. The purpose of this content review was to identify core standards and competencies essential to an interprofessional team providing end-of-life care. Methods: The researchers conducted a review of health professional associations and registration bodies that support professionals providing end-of-life care to identify existing standards and competencies. Key concepts were reviewed and organized using thematic analysis; relationships were developed; and core themes for interprofessional end-of-life care were identified. Results: Four themes essential to the provision of end-of-life care were common across all health professions: (1) access to care, (2) professional practice, (3) person-centered care, and (4) the process and delivery of care. Conclusions: Health professional associations need to ensure end-of-life care standards and competencies are in place for the provision of appropriate and holistic care. Aligning standards and competencies across professions improves the preparedness of health professionals to provide interprofessional end-of-life care.

Published: June 2020

Introduction: Patients with chronic obstructive pulmonary disease and interstitial lung disease have a significant burden of symptoms. Many are not offered palliative care (PC). Our aim was to investigate the attitudes to and barriers for PC among physicians. Method: A web-based survey was conducted among members of the Danish Respiratory Society. The questionnaire included contextual (gender, age, clinical experience, type of center, patient caseload) and outcome questions (knowledge and use of statements for PC and advance care planning [ACP], practice of communication about end-of-life decisions, practice for referral to PC, barriers regarding structural surroundings, clinical skills, and organization). Results: One hundred fifty-six (45%) physicians responded. Median age was 40 - 49 years and 55% were female. Fifty-two percent were specialists; 71% worked at a university hospital. The majority of physicians (60%) reported barriers for discussions about PC and ACP; 63% reported lack of time, 52% lack of multidisciplinary staff settings, 63% reported the unpredictability of the prognosis, and 20% insufficient awareness of patient’s culture, religion, or spirituality. Fewer specialists than nonspecialists reported barriers toward ACP. The majority had knowledge of guidelines in PC and ACP, but only a minority used these in daily clinical practice. Conclusion: The attitude toward PC and ACP conversations was positive and implementation was regarded as important, but only a minority performed these conversations in practice. Main barriers were lack of time and staff. Palliative care guidelines were known but only scarcely used. Structural changes at the organizational level to improve access to palliation for patients with nonmalignant chronic lung diseases are needed.

Objectives Primary nasal tumours in cats are rare, with lymphoma being the most common feline nasal tumour, followed by adenocarcinoma. Although CT can reliably detect feline nasal tumours, there are no specific CT features that identify each tumour type. To our knowledge, there have been no reports describing MRI findings, including diffusion-weighted imaging (DWI), for nasal lymphomas and adenocarcinomas in cats. Therefore, this retrospective study aimed to evaluate the MRI findings of nasal lymphoma and adenocarcinoma, including qualitative and quantitative analysis of DWI. Methods MRI examination was performed on seven cats with histologically confirmed lymphoma and on two with adenocarcinoma. The MRI protocol included T2-weighted imaging (T2WI), T1-weighted imaging (T1WI) and DWI. Apparent diffusion coefficient (ADC) values were measured using DWI. Contrast agent was not used in one cat with lymphoma. Results Of the cats with lymphoma, three (43%) were iso- and hyperintense on T2WI, seven (100%) were isointense on T1WI, five (83%) exhibited mild heterogeneous enhancement, including a prominent region of non-enhancement on post-contrast T1WI, and seven (100%) cats exhibited hyperintensity on DWI. The median ADC values were 0.45 × 10−3 mm2/s (range 0.37–0.53 × 10−3 mm2/s). For adenocarcinoma, two (100%) were iso- and hyperintense on T2WI, two (100%) were isointense on T1WI, two (100%) exhibited marked heterogeneous enhancement on post-contrast T1WI and two (100%) were isointense on DWI. The median ADC values were 1.08 × 10−3 mm2/s (range 0.88–1.27 × 10−3 mm2/s). The median ADC values of lymphoma tended to be lower than adenocarcinoma ( P = 0.056). Conclusions and relevance Determining ADC value and tumours with a large area of non-enhancement may be helpful in differentiating nasal lymphoma from nasal adenocarcinoma.
