- Abstract
BACKGROUND: Low plasma concentrations of HDLs are associated with an increased risk of coronary artery disease. Two uncontrolled studies suggested that plant monoterpenes may have substantial HDL-cholesterol-elevating activity in humans. Each study used a proprietary mixture of 6 monoterpenes in olive oil. OBJECTIVE: The present study was undertaken to test more rigorously the hypothesis that monoterpenes raise HDL concentrations in men with hypoalphalipoproteinemia. DESIGN: A double-blind, placebo-controlled crossover design was used. Twenty-four men aged 58-68 y (x: 62.3 y) with plasma HDL cholesterol <1.1 mmol/L, plasma triacylglycerols <3.5 mmol/L, and plasma total cholesterol <5.5 mmol/L at recruitment were randomly assigned to 6 capsules daily of a proprietary mixture of 6 monoterpenes in olive oil or 6 capsules daily of olive oil alone for 24 wk, followed by a washout period of 8 wk, and then the alternative capsules for 24 wk. RESULTS: Five men dropped out. In the others, compliance was excellent as judged by capsule counts and urinary menthol glucuronide concentrations. No significant effects were observed on plasma HDL-cholesterol or apolipoprotein A-I concentrations, nor on plasma triacylglycerol, LDL-cholesterol, or apolipoprotein B concentrations. CONCLUSIONS: Plant monoterpenes have no HDL-elevating activity of potential value for coronary artery disease prevention.

1. Seven patients with type II hyperlipoproteinaemia were treated with the bile acid-sequestering resin, colestipol (5 g three times daily), after a prolonged period of taking placebo. 2. After 8–9 weeks of treatment, the plasma concentration of the non-esterified cholesterol of very-low-density lipoprotein (VLDL) had risen by a mean of 0.09 mmol/l (43% increase, P < 0.001), that of the esterified cholesterol of VLDL had risen by a mean of 0.11 mmol/l (38% increase, P < 0.01), and that of the triglyceride of VLDL had risen by a mean of 0.40 mmol/l (53% increase, P 3. During the early period of treatment with colestipol, changes took place in the specific radioactivity of plasma cholesterol (labelled by intravenous injection of [3H]cholesterol), which, together with the changes in the mass of cholesterol within the individual plasma lipoproteins, were consistent with an increased influx into plasma of non-esterified cholesterol within VLDL, and an increased efflux of cholesterol from plasma within LDL.

The turnover of plasma-esterified cholesterol can be measured in vivo after injection of radiomevalonate. Values obtained in vivo are similar to measurements made in vitro. Esterification of cholesterol occurs mainly in plasma: when cholesterol synthesis is stimulated, newly formed cholesterol enters plasma predominantly unesterified. When cholesterol turnover is increased, plasma cholesterol-esterifying activity rises proportionately. The turnover of esterified cholesterol is increased in obesity, in Type 4 hyperlipoproteinaemia, and during carbohydrate-rich diets; since the turnover of lipoproteins, especially VLDL, is probably also increased under these conditions, esterified cholesterol appears to have an important role in plasma lipid transport.

In vitro plasma cholesterol esterifying activity was measured before and during therapy with the bile acid-sequestering resin, colestipol. In seven subjects with type II hyperlipoproteinemia, long-term therapy was associated with a 53% ± 17.1% increase in activity expressed as per cent FC esterified per hour, and a 37% ± 23.8% increase in terms of μg FC per ml plasma esterified per hour (mean ± SD). This increase occurred despite a fall in the plasma concentration of cholesterol. Activity was positively correlated with the rate of cholesterol turnover (measured by isotope dilution analysis and sterol balance) (r = +0.87, p < 0.001). Values before colestipol therapy for total plasma cholesterol esterifying activity exceeded those for cholesterol turnover (1.69 ± 0.22 vs. 1.22 ± 0.16 g/day, mean ± SD, n = 7), but they did not differ significantly during colestipol therapy (2.17 ± 0.19 vs. 2.34 ± 0.40 g/day, n = 6). The findings suggest that most exchangeable cholesterol molecules are at some stage esterified within plasma on at least one occasion during the normal turnover of body cholesterol.

The plasma concentration of unesterified and esterified cholesterol within very low density (VLDL), low density (LDL) and high density (HDL) lipoproteins have been examined in relation to the metabolism and pool size of cholesterol in normal and hyperlipidaemic subjects. Cholesterol metabolism was assessed as faecal endogenous neutral and acidic steroid excretion, a 2-pool model of cholesterol turnover, and in vitro plasma cholesterol esterifying activity. VLDL total cholesterol (TC) concentration was positively correlated with cholesterol turnover, endogenous neutral steroid excretion, bile acid excretion and the absolute rate of plasma cholestrol esterification. The correlations with cholesterol turnover and neutral steroid excretion, but not that with bile acid excretion, remained significant when these were corrected for their relationships to body weight. LDL-TC was negatively correlated with the fractional rate of plasma cholesterol esterification and, in subjects with primary type IIa hyperlipoproteinaemia, also with the rate constant for cholesterol elimination from the rapidly exchanging cholesterol pool. No correlation was found between LDL-TC concentration and bile acid excretion. HDL-TC concentration was negatively correlated with both the rapidly and slowly exchanging pools of tissue cholesterol, after correction for their relationships to body weight and adiposity. In contrast, cholesterol pool sizes were not correlated with the concentration of VLDL or LDL-TC; nor was there any relationship to plasma cholesterol esterifying activity. No correlation was found between the relative proportions of unesterified cholesterol within any lipoprotein fraction and either the pool size or metabolism of cholesterol. These findings accord with previous reports of enhanced cholesterol metabolism in subjects with elevated VLDL concentrations and of impaired plasma LDL and cholesterol clearance in patients with primary type IIa hyperlipoproteinaemia. The demonstration that HDL-TC concentration is negatively correlated with body cholesterol pool size supports in vitro evidence for a role of HDL IN TISSUE CHOLESTEROL CLEARENCE.

A variety of epidemiologic, biochemical, and experimental studies have established a direct relationship between low density lipoprotein (LDL) cholesterol concentration and the risk of developing ischemic heart disease. An even stronger inverse relationship has been demonstrated between high density lipoprotein (HDL) cholesterol and the risk of ischemic heart disease (IHD). Both of these associations reflect underlying relationships to atherogenesis. The mechanism by which elevated LDL levels lead to cholesterol ester deposition in arterial smooth muscle cells and/or macrophages is not clear. a causal relationship between low HDL levels and accelerated atherogenesis has not yet been established. Factors which increase plasma LDL concentration or reduce HDL concentration, with a consequent increase in the theoretical risk of coronary atherosclerosis, include obesity, physical inactivity, cigarette smoking, and progestin-containing oral contraceptives. Recent reports have added to this list widely used antihypertensive agents, such as thiazide diuretics and beta-blocking agents. The mechanisms and pathophysiologic significance of such drug-induced changes in lipoprotein levels are not clear. Until more information is available, however, it would seem prudent to avoid, whenever possible, any antihypertensive which in a given patient substantially lowers the HDL/LDL ratio.

- Abstract
Cue reactivity is the maladaptive neurobiological and behavioral response upon exposure to drug cues and is a major driver of relapse. A widely accepted assumption is that drugs of abuse result in disparate dopamine responses to cues that predict drug vs. natural rewards. The leading hypothesis is that drug-induced dopamine release represents a persistently positive reward prediction error that causes runaway enhancement of dopamine responses to drug cues, leading to their pathological overvaluation. However, this hypothesis has not been directly tested. Here, we develop Pavlovian and operant procedures in male rats to measure firing responses within the same dopamine neurons to drug versus natural reward cues, which we find to be similarly enhanced compared to cues predicting natural rewards in drug-naive controls. This enhancement is associated with increased behavioral reactivity to the drug cue, suggesting that dopamine neuronal activity may still be relevant to cue reactivity, albeit not as previously hypothesized. These results challenge the prevailing hypothesis of cue reactivity, warranting revised models of dopaminergic function in opioid addiction, and provide insights into the neurobiology of cue reactivity with potential implications for relapse prevention., Competing Interests: Competing interests: The authors declare no competing interests., (© 2025.

- Abstract
Objectives: Primary human papillomavirus (HPV) testing by clinician-collection is endorsed by U.S. guideline organizations for cervical cancer screening, but uptake remains low and insights into patients' understanding are limited. This study aims to primarily address patient awareness of primary HPV screening by clinician-collection and acceptance of primary HPV screening by clinician- and self-collection, and secondarily assess factors associated with awareness and acceptance., Setting: Primary care practices affiliated with an academic medical center., Methods: A cross-sectional survey study of screening-eligible women aged 30-65 years was conducted to assess awareness and acceptability of primary HPV screening. We analyzed bivariate associations of respondent characteristics with awareness of primary HPV screening by clinician-collection, willingness to have clinician- or self-collected primary HPV testing, and reasons for self-collection preference., Results: Respondents (n = 351; response rate = 23.4%) reported cervical cancer screening adherence of 82.8% but awareness of clinician-collected primary HPV as an option was low (18.9%) and only associated with HPV testing with recent screening ( p = 0.003). After reviewing a description of primary HPV screening, willingness for clinician-collected (81.8%) or home self-collected (76.1%) HPV testing was high, if recommended by a provider. Acceptability of clinician-collected HPV testing was associated with higher income ( p = 0.009) and for self-collection was associated with higher income ( p = 0.002) and higher education ( p = 0.02). Higher education was associated with reporting self-collection as easier than clinic-collection ( p = 0.02). Women expected self-collection to be more convenient (94%), less embarrassing (85%), easier (85%), and less painful (81%) than clinician-collection., Conclusions: Educational interventions are needed to address low awareness about the current clinician-collected primary HPV screening option and to prepare for anticipated federal licensure of self-collection kits. Informing women about self-collection allows them to recognize benefits which could address screening barriers., Competing Interests: Declaration of conflicting interestsThe authors declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

- Abstract
This study aimed to examine whether psychological distress was cross-sectionally associated with meeting World Cancer Research Fund (WCRF) recommendations in people living with and beyond cancer. Participants were adults living with and beyond breast, prostate and colorectal cancer, participating in the baseline wave of the Advancing Survivorship after Cancer Outcomes Trial (ASCOT). Anxiety/depression was assessed using the EQ-5D-5L and dichotomised into any/no problems. WCRF recommendations were assessed via pedometers, 24-h dietary recalls, self-reported alcohol intake (AUDIT-C), and self-reported smoking status. Participants were categorised as meeting WCRF recommendations using the following cut-offs: average daily steps (≥ 10,000/day), average weekly aerobic steps (≥ 15,000/day), fruit and vegetables (≥ 400 g/day), fibre (≥ 30 g/day), red meat (< 500 g/week), processed meat (0 g/day), high calorie food (fat ≤ 33% of total daily energy intake and free sugar ≤ 5% of total daily energy intake), alcohol (≤ 14 units/week) and smoking (non-smoking). A composite health behaviour risk index (CHBRI) was calculated by summing the number of WCRF recommendations met (range: 0-9). Among 1348 participants (mean age = 64 years (SD = 11.4)), 41.5% reported anxiety/depression problems. The mean CHBRI score was 4.4 (SD = 1.4). Anxiety/depression problems were associated with lower odds of meeting WCRF recommendations for average daily steps (odds ratio (OR) = 0.73; 95% CI 0.55, 0.97), but not for any other health behaviour. Psychological distress is associated with lower adherence to WCRF recommendations for physical activity in people living with and beyond cancer. Physical activity may be a mechanism linking psychological distress and poorer outcomes among people living with and beyond cancer, and this should be explored in longitudinal studies., (© 2024.

- Abstract
Objective: Evidence shows that higher depressive symptoms are associated with mortality among people living with and beyond cancer (LWBC). However, prior studies have not accounted for a wider range of potential confounders, and no study has explored whether socioeconomic position (SEP) moderates the association. This study aimed to examine the association between depressive symptoms and mortality among people LWBC, and moderation by SEP., Methods: Participants from the English Longitudinal Study of Aging, diagnosed with cancer and with a measure of depressive symptoms within 4 years after their diagnosis, were included. Elevated depressive symptoms were indicated by a score of ≥3 on the eight-item Center for Epidemiologic Studies Depression Scale. Cox regression models examined associations with all-cause mortality. Competing risk regression examined associations with cancer mortality., Results: In 1352 people LWBC (mean age = 69.6 years), elevated depressive symptoms were associated with a 93% increased risk of all-cause mortality (95% confidence interval = 1.52-2.45) within the first 4 years of follow-up and a 48% increased risk within a 4- to 8-year follow-up (95% confidence interval = 1.02-2.13) after multivariable adjustment. Elevated depressive symptoms were associated with a 38% increased risk of cancer mortality, but not after excluding people who died within 1 year after baseline assessments. There were no interactions between depressive symptoms and SEP., Conclusions: Elevated depressive symptoms are associated with a greater risk of all-cause mortality among people LWBC within an 8-year follow-up period. Associations between depressive symptoms and cancer mortality might be due to reverse causality., (Copyright © 2024 The Author(s).

- Abstract
Cue reactivity is the maladaptive neurobiological and behavioral response upon exposure to drug cues and is a major driver of relapse. The leading hypothesis is that dopamine release by addictive drugs represents a persistently positive reward prediction error that causes runaway enhancement of dopamine responses to drug cues, leading to their pathological overvaluation compared to non-drug reward alternatives. However, this hypothesis has not been directly tested. Here we developed Pavlovian and operant procedures to measure firing responses, within the same dopamine neurons, to drug versus natural reward cues, which we found to be similarly enhanced compared to cues predicting natural rewards in drug-naïve controls. This enhancement was associated with increased behavioral reactivity to the drug cue, suggesting that dopamine release is still critical to cue reactivity, albeit not as previously hypothesized. These results challenge the prevailing hypothesis of cue reactivity, warranting new models of dopaminergic function in drug addiction, and provide critical insights into the neurobiology of cue reactivity with potential implications for relapse prevention.

Miller NE, North F, Curry EN, Thompson MC, and Pecina JL
- Abstract
Introduction: Online symptom checkers are a way to address patient concerns and potentially offload a burdened healthcare system. However, safety outcomes of self-triage are unknown, so we reviewed triage recommendations and outcomes of our institution's depression symptom checker., Methods: We examined endpoint recommendations and follow-up encounters seven days afterward during 2 December 2021 to 13 December 2022. Patients with an emergency department visit or hospitalization within seven days of self-triaging had a manual review of the electronic health record to determine if the visit was related to depression, suicidal ideation, or suicide attempt. Charts were reviewed for deaths within seven days of self-triage., Results: There were 287 unique encounters from 263 unique patients. In 86.1% (247/287), the endpoint was an instruction to call nurse triage; in 3.1% of encounters (9/287), instruction was to seek emergency care. Only 20.2% (58/287) followed the recommendations given. Of the 229 patients that did not follow the endpoint recommendations, 121 (52.8%) had some type of follow-up within seven days. Nearly 11% (31/287) were triaged to endpoints not requiring urgent contact and 9.1% (26/287) to an endpoint that would not need any healthcare team input. No patients died in the study period., Conclusions: Most patients did not follow the recommendations for follow-up care although ultimately most patients did receive care within seven days. Self-triage appears to appropriately sort patients with depressed mood to emergency care. On-line self-triaging tools for depression have the potential to safely offload some work from clinic personnel., Competing Interests: Declaration of conflicting interestsThe authors declared no potential conflicts of interest with respect to the research, authorship and/or publication of this article.

- Abstract
Background: Dorsolateral prefrontal cortex (DLPFC) dysfunction in schizophrenia appears to reflect alterations in layer 3 pyramidal neurons (L3PNs), including smaller cell bodies and lower expression of mitochondrial energy production genes. However, prior somal size studies used biased strategies for identifying L3PNs, and somal size and levels of energy production markers have not been assessed in individual L3PNs., Study Design: We combined fluorescent in situ hybridization (FISH) of vesicular glutamate transporter 1 (VGLUT1) mRNA and immunohistochemical-labeling of NeuN to determine if the cytoplasmic distribution of VGLUT1 mRNA permits the unbiased identification and somal size quantification of L3PNs. Dual-label FISH for VGLUT1 mRNA and cytochrome C oxidase subunit 4I1 (COX4I1) mRNA, a marker of energy production, was used to assess somal size and COX4I1 transcript levels in individual DLPFC L3PNs from schizophrenia (12 males; 2 females) and unaffected comparison (13 males; 1 female) subjects., Study Results: Measures of L3PN somal size with NeuN immunohistochemistry or VGLUT1 mRNA provided nearly identical results (ICC = 0.96, p < 0.0001). Mean somal size of VGLUT1-identified L3PNs was 8.7% smaller (p = 0.004) and mean COX4I1 mRNA levels per L3PN were 16.7% lower (p = 0.01) in schizophrenia. These measures were correlated across individual L3PNs in both subject groups (r
rm = 0.81-0.86)., Conclusions: This preliminary study presents a novel method for combining unbiased neuronal identification with quantitative assessments of somal size and mRNA levels. We replicated findings of smaller somal size and lower COX4I1 mRNA levels in DLPFC L3PNs in schizophrenia. The normal scaling of COX4I1 mRNA levels with somal size in schizophrenia suggests that lower markers of energy production are secondary to L3PN morphological alterations in the illness., (Copyright © 2024 The Authors.

Pre and post surveys of the educational material were completed in 2 sections including one gauging medical knowledge and a second part gauging level of comfort., Results: Of the learners who participated, fourteen completed the pre-post surveys. Most (53%) respondents improved their scores, while 20% scored the same 27% scored worse. The overall average score increased 57% to 70% and improvement was statistically significant ( P < .05). All learners improved confidence by at least 1 point., Conclusion: An interprofessional team utilizing a lecture curriculum focusing on providing education on effective prescribing, medication safety profiles, and resource availability, showed improvement in confidence but mixed knowledge benefit. Further modifications to the curriculum may yield further educational gains., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

- Abstract
Background: Greater physical activity is associated with improved outcomes in people living with and beyond cancer. However, most studies in exercise oncology use self-reported measures of physical activity. Few have explored agreement between self-reported and device-based measures of physical activity in people living with and beyond cancer. This study aimed to describe physical activity in adults affected by cancer across self-reported and device-assessed activity, to explore levels of agreement between these measures in terms of their utility for categorizing participants as meeting/not meeting physical activity guidelines, and to explore whether meeting guidelines is associated with fatigue, quality of life, and sleep quality., Methods: A total of 1348 adults living with and beyond cancer from the Advancing Survivorship Cancer Outcomes Trial completed a survey assessing fatigue, quality of life, sleep quality, and physical activity. The Godin-Shephard Leisure-Time Physical Activity Questionnaire was used to calculate a Leisure Score Index (LSI) and an estimate of moderate-to-vigorous physical activity (MVPA). Average daily steps and weekly aerobic steps were derived from pedometers worn by participants., Results: The percentage of individuals meeting physical activity guidelines was 44.3% using LSI, 49.5% using MVPA, 10.8% using average daily steps, and 28.5% using weekly aerobic steps. Agreement (Cohen's κ) between self-reported and pedometer measures ranged from 0.13 (LSI vs. average daily steps) to 0.60 (LSI vs. MVPA). After adjusting for sociodemographic and health-related covariates, meeting activity guidelines using all measures was associated with not experiencing severe fatigue (odds ratios (ORs): 1.43-1.97). Meeting guidelines using MVPA was associated with no quality-of-life issues (OR = 1.53). Meeting guidelines using both self-reported measures were associated with good sleep quality (ORs: 1.33-1.40)., Conclusion: Less than half of all adults affected by cancer are meeting physical activity guidelines, regardless of measure. Meeting guidelines is associated with lower fatigue across all measures. Associations with quality of life and sleep differ depending on measure. Future research should consider the impact of physical activity measure on findings, and where possible, use multiple measures., (Copyright © 2023. Production and hosting by Elsevier B.V.)

- Abstract
Hyponatremia and hypernatremia are electrolyte disorders that can be associated with poor outcomes. Hyponatremia is considered mild when the sodium concentration is 130 to 134 mEq per L, moderate when 125 to 129 mEq per L, and severe when less than 125 mEq per L. Mild symptoms include nausea, vomiting, weakness, headache, and mild neurocognitive deficits. Severe symptoms of hyponatremia include delirium, confusion, impaired consciousness, ataxia, seizures, and, rarely, brain herniation and death. Patients with a sodium concentration of less than 125 mEq per L and severe symptoms require emergency infusions with 3% hypertonic saline. Using calculators to guide fluid replacement helps avoid overly rapid correction of sodium concentration, which can cause osmotic demyelination syndrome. Physicians should identify the cause of a patient's hyponatremia, if possible; however, treatment should not be delayed while a diagnosis is pursued. Common causes include certain medications, excessive alcohol consumption, very low-salt diets, and excessive free water intake during exercise. Management to correct sodium concentration is based on whether the patient is hypovolemic, euvolemic, or hypervolemic. Hypovolemic hyponatremia is treated with normal saline infusions. Treating euvolemic hyponatremia includes restricting free water consumption or using salt tablets or intravenous vaptans. Hypervolemic hyponatremia is treated primarily by managing the underlying cause (e.g., heart failure, cirrhosis) and free water restriction. Hypernatremia is less common than hyponatremia. Mild hypernatremia is often caused by dehydration resulting from an impaired thirst mechanism or lack of access to water; however, other causes, such as diabetes insipidus, are possible. Treatment starts with addressing the underlying etiology and correcting the fluid deficit. When sodium is severely elevated, patients are symptomatic, or intravenous fluids are required, hypotonic fluid replacement is necessary.

- Abstract
Background: Although online self-triage is easily accessible, little is known about the patients who use self-triage or their subsequent diagnoses. We compared ear/hearing self-triage subsequent diagnoses to ear/hearing visit diagnoses in emergency departments (ED) and ambulatory clinics across the United States., Methods: We compared International Classification of Diseases version 10 (ICD10) coded diagnoses following online self-triage for ear/hearing concerns with those from national ED and ambulatory clinic samples. We used data from the Centers for Disease Control (CDC) National Hospital Ambulatory Medical Care Survey (NHAMCS) and National Ambulatory Medical Care Survey (NAMCS) for comparison. Using matched ear/hearing diagnostic categories for those aged 1 and over, we compared self-triage diagnosis frequencies with national ED and ambulatory diagnosis frequencies., Results: Following ear/hearing self-triage, there were 1092 subsequent office visits with a primary diagnosis code. For five frequently diagnosed ear/hearing conditions (i.e., suppurative and nonsuppurative otitis media [OM], otalgia, otitis externa, and cerumen impaction), there was a strong correlation between diagnosis counts made following self-triage and estimated counts of national ED visit diagnoses (r = 0.94; CI 95% [0.37 to 0.99]; p = .016, adjusted r
2 = 0.85). Seven diagnoses were available to compare with the national ambulatory sample; correlation was r = 0.79; CI 95% [0.08 to 0.97]; p = .037, adjusted r2 = 0.54. For ages 1 and over, estimated hospital admissions from the national ED visits for ear/hearing were 0.76%, CI 95% [0.28-2.1%]; estimated total national ear/hearing ED visits were 7.5 million (for 4 years, 2016 through 2019)., Conclusion: The strong correlation of ear-related self-triage diagnoses with national ED diagnoses and the low hospitalization risk for these diagnoses suggests that there is an opportunity for self-triage of ear/hearing concerns to decrease ED visits for these symptoms., Competing Interests: The author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article., (© The Author(s) 2023.)- Published

- Abstract
Introduction: Acute sore throat is a common complaint traditionally completed with an in-person visit. However, non-face-to-face telemedicine visits offer greater access at reduced cost. We evaluated patient/caregiver asynchronous text-based electronic visits (eVisits) for acute sore throat and whether there was concordance for individual components and total McIsaac score compared to a clinician's assessment. eVisits were completed by patients and/or their caregivers via a secure patient portal., Methods: In this retrospective study, we manually reviewed charts between February 2017 and July 2019 of patients who had an eVisit, in-person visit and group A streptococcal (GAS) test performed on the same day for an acute sore throat. We calculated a McIsaac score for eVisits and in-person visits, and compared each component and total score using Cohen's kappa agreement statistic., Results: There were 320 instances of patients who had an eVisit, in-person visit and GAS testing done on the same day. Approximately a third of eVisits were missing at least one McIsaac component, with the physical examination elements missing most commonly. Individual score congruence was moderate for cough (0.41), fair for fever (0.34) and slight for tonsillar swelling/exudate and lymphadenopathy (0.17 and 0.08, respectively), with total congruence being slight to fair (0.09-0.37). A McIsaac score of ≤1 showed moderate agreement (0.44). Visits with complete individual score components demonstrated improved congruence: substantial for cough (0.64), moderate for fever (0.57), fair for tonsillar swelling (0.3) and slight for lymphadenopathy (0.13)., Discussion: Overall agreement for individual score components was better for symptoms than it was for examination components, and was improved when data were complete. A McIsaac score of 1 or 0 had moderate agreement and thus could reasonably be safely used to exclude patients from GAS testing.

- Abstract
Background: Many individuals living with and beyond cancer (LWBC) have ongoing quality of life (QoL) issues, including fatigue. The World Cancer Research Fund (WCRF) provides health behaviour recommendations for people LWBC, and there is some evidence linking adherence to these with improved QoL., Methods: Adults LWBC (specifically breast, colorectal or prostate cancer) completed a survey covering health behaviours (diet, physical activity, alcohol consumption and smoking), fatigue (FACIT-Fatigue Scale, version 4) and a broad measure of QoL (EQ-5D-5L descriptive scale). Participants were categorised as meeting/not meeting WCRF recommendations, using the following cut-offs classified as meeting the guidelines: ≥150 min physical activity/week, fruit and vegetables (≥5 portions/day), fibre (≥30 g fibre per day), free sugar (<5% of total calories from free sugar), fat (<33% total energy), red meat (<500 g/week), processed meat (none), alcohol consumption (<14 units/week) and not a current smoker. Logistic regression analyses explored associations between WCRF adherence and fatigue and QoL issues, controlling for demographic and clinical variables., Results: Among 5835 individuals LWBC (mean age: 67 years, 56% female, 90% white, breast 48%, prostate 32% and colorectal 21%), 22% had severe fatigue and 72% had 1+ issue/s on the EQ-5D-5L. Adhering to physical activity recommendations (odds ratio [OR] = 0.88, confidence interval [CI] = 0.77-0.99), meeting various dietary recommendations (fruit and vegetables OR = 0.79; CI = 0.68-0.91, free sugar OR = 0.85; CI = 0.76-0.96, fat OR = 0.71; CI = 0.62-0.82, red meat OR = 0.65; CI = 0.50-0.85) and not smoking (OR = 0.53, CI = 0.41-0.67) were associated with decreased odds of experiencing severe fatigue. Adhering to physical activity guidelines (OR = 0.71, CI = 0.62-0.82) was also associated with decreased odds of having 1+ QoL issue/s., Conclusions: Adherence to various WCRF recommendations, particularly the recommendation for physical activity, was associated with less fatigue and better QoL in a large UK cohort of people living with and beyond breast, colorectal or prostate cancer. Multi-component interventions designed to support people LWBC to improve health behaviours, in line with the levels recommended by the WCRF, may also improve QoL., (© 2023 The Authors.

- Abstract
Objective: Central adiposity is associated with impaired biological responses to mental stress, and socioeconomic status (SES) might moderate this relationship. However, evidence for associations between pericardial fat, a fat depot implicated in the pathogenesis of cardiovascular disease (CVD), with cardiovascular and inflammatory responses to mental stress is lacking, and moderation by SES is unknown., Methods: The sample was 473 healthy men and women (mean age = 62.8 years) from the Whitehall II study. Cardiovascular and inflammatory responses to laboratory-induced mental stress, consisting of a 5-minute Stroop task and 5-minute mirror tracing task, were assessed. Pericardial fat volume was measured using electron bean computed tomography and adjusted for body surface area. SES was defined by grade of employment within the British civil service (higher/intermediate/lower)., Results: Pericardial fat was associated with lower heart rate variability, raised heart rate, plasma interleukin-6, fibrinogen, and C-reactive protein at baseline. Furthermore, greater pericardial fat was associated with lower systolic blood pressure reactivity to mental stress, independent of sociodemographics, smoking status, waist-to-hip ratio, and baseline systolic blood pressure. There were no interactions between pericardial fat and SES for any outcome., Conclusions: Greater pericardial fat was associated with numerous cardiovascular and inflammatory factors implicated in CVD. It was also related to reduced systolic blood pressure reactivity to acute mental stress, independent of central adiposity and baseline systolic blood pressure. This association did not vary by SES. Reduced systolic blood pressure reactivity to mental stress might contribute to the association between greater pericardial fat and CVD., (Copyright © 2022 The Author(s).

- Abstract
Purpose: Stigma related to mental health is well documented and a major barrier to using mental and physical health care. Integrated behavioral health (IBH) in primary care, in which behavioral/mental health care services are located within a primary care setting, may reduce the experience of stigma. The purpose of this study was to assess the opinions of patients and health care professionals about mental illness stigma as a barrier to engagement with IBH and to gain insight into strategies to reduce stigma, encourage discussion of mental health, and increase uptake of IBH care., Methods: We conducted semistructured interviews with 16 patients referred to IBH in a prior year and 15 health care professionals (12 primary care physicians and 3 psychologists). Interviews were transcribed and inductively coded separately by 2 coders for common themes and subthemes under the topic headings of barriers, facilitators, and recommendations., Results: We identified 10 converging themes from interviews with patients and the health care professionals, representing important complementary perspectives, with respect to barriers, facilitators, and recommendations. Barriers included professionals, families, and the public as sources of stigma, as well as self-stigma or avoidance, or internalizing negative stereotypes. Facilitators and recommendations included normalizing discussion of mental health and mental health care-seeking action, using patient-centered and empathetic communication strategies, sharing by health care professionals of their own experiences, and tailoring the discussion of mental health to patients' preferred understanding., Conclusions: Health care professionals can help reduce perceptions of stigma by having conversations with patients that normalize mental health discussion, use patient-centered communication, promote professional self-disclosure, and are tailored to patients' preferred understanding., Competing Interests: Conflicts of interest: authors report none., (© 2023 Annals of Family Medicine, Inc.)

- Abstract
An elderly man with COPD and heart failure was admitted to the Family Medicine Inpatient Service from the Emergency Department (ED) after experiencing acute onset of shortness of breath at home. He had recently been briefly hospitalized with COVID pneumonia. Upon arrival in the ED, he was requiring continuous positive airway pressure to maintain oxygen saturations. Overall, physical exam was notable for mild respiratory distress. Lab evaluation was unremarkable, but chest x-ray showed a right sided pneumothorax. Spontaneous pneumothoraces have been described in post-COVID cases, with COPD and mechanical ventilation thought to be risk factors. Treatment consists of supportive cares, needle decompression and thoracostomy if necessary. Providers should be aware of this rare albeit serious complication and monitor higher risk patients appropriately.

- Abstract
A healthy 15-year-old right-hand dominant football player presented to the clinic for a preparticipation examination (PPE) with an exam notable for reduced right shoulder range of motion. The patient reported no complaints, including no pain. Upon questioning, he noted a remote non-sports related injury to that shoulder with unremarkable radiographs at that time. Subsequent X-ray imaging showed a bony abnormality thought to be consistent with an osteochondroma. However, advanced imaging identified it as a heterotrophic ossification center that required a complex, multidisciplinary surgical team to correct. This case of a high school football player's routine PPE that resulted in surgery highlights not only whether sport participation is safe, but also the importance of direct, specific language that asks about the history of any injuries, rather than specifically sports related.

- Abstract
To examine whether high school student-athletes who experienced more COVID-19 disruptions had increased anxiety, increased dejection, increased anger, decreased excitement, and decreased happiness as measured by the validated Sports Emotion Questionnaire (SEQ). During the COVID-19 pandemic high school student-athletes faced disruptions which resulted in cancelation of competitions, reduced in-person training sessions, and quarantine of athletes. The impact of these disruptions on the mental health and well-being of student-athletes is unknown. An anonymous cross-sectional online survey was electronically distributed to high school student-athletes in one school district during the spring of the 2020 to 21 academic year. Basic demographic questions, sport information, and personal and team disruptions were collected. Multivariate linear regression was used to assess correlation between each emotional domain on the SEQ with independent variables such as personal or teammate quarantines, cancelations, season, sport gender, indoor or outdoor location, and level of competition. 125 surveys were returned representing 28 different sports. Student-athletes who were personally quarantined (22.4%) during their athletic season experienced greater dejection (β = 0.78, P = .003) and greater anger (β = 0.78, P = .005). Those with teammates quarantined (61.6%) experienced more anxiety (β = 0.30, P = .048). Spring sports, which faced fewer restrictions, were associated with less anger (β = -0.48, P = .048). Student-athletes who were directly affected by COVID-19 disruptions experienced increased anxiety, more dejection, and more anger. Public health authorities and school districts should minimize disruptions to athletic participation using established COVID-19 safety protocols to avoid causing harm to athletes' social-emotional well-being. If athletics must be disrupted, student-athletes should receive wellness support and virtual or remote training options., Competing Interests: The authors have no conflicts of interest to disclose., (Copyright © 2022 the Author(s).

- Abstract
Objective: Many Black breast cancer patients experience chemotherapy-induced peripheral neuropathy (CIPN). Our study assessed Black breast cancer patients' questions about a biomarker test that can predict likelihood of CIPN., Methods: Nineteen Black women who were previous/current breast cancer patients participated in focus groups. Researchers briefly explained CIPN and the biomarker test, and then participants were asked what questions they would have about the test and its use in treatment decisions. These participant-voiced questions composed the data for this study and were analyzed using thematic analysis., Results: Participants' questions centered on six themes: reasons for the test, effect on timeline of breast cancer treatment, testing procedure, limits of test (including accuracy), research done to develop this test (including research participants), and concerns about personal information connected to the test (including DNA)., Conclusion: This study provides an exploratory look at questions that Black breast cancer patients may have about toxicity biomarker testing use in breast cancer treatment decisions., Innovation: These findings provide a starting point for developing patient-centered approaches for integrating this precision medicine tool into clinical care. The methodological choice to generate participants' questions (rather than answers to a question) led to robust, actionable data., Competing Interests: The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: All authors reports financial support was provided by Susan G Komen Breast Cancer Foundation.

Miller NE and Lacey RE
- Abstract
Studies that have examined associations between adverse childhood experiences (ACEs) and cardiometabolic biomarkers in adulthood are limited as they mainly focus on childhood maltreatment. This study aimed to examine the association between a range of prospectively and retrospectively reported ACEs and cardiometabolic biomarkers in mid-adulthood. Multiply-imputed data on 8511 participants from the National Child Development Study (1958 British birth cohort) were used. ACEs were prospectively reported at ages 7, 11 and 16, and retrospectively reported at age 33/44/45. Cardiometabolic outcomes assessed at age 44/45 included glycated haemoglobin (HbA1c), cholesterol (total, low-density lipoprotein (LDL) and high-density lipoprotein (HDL)), triglycerides, blood pressure (systolic and diastolic), body mass index, waist circumference and metabolic syndrome. Parental separation/divorce, physical neglect, emotional neglect and psychological abuse were associated with lower HDL cholesterol. Parental offending and physical neglect were associated with higher triglyceride concentrations. Parental offending was also associated with increased HbA1c. Exposure to 2+ (vs. 0) prospective ACEs was associated with lower HDL cholesterol. All these associations were after adjustment for sex and multiple early life factors. To conclude, several individual ACEs are associated with poorer cardiometabolic risk factor profiles in mid-adulthood. Furthermore, exposure to two or more prospective ACEs is associated with lower HDL cholesterol concentrations in mid-adulthood., Competing Interests: None., (© 2022 The Authors.)

- Abstract
Depressive symptoms are associated with increased risk for cardiovascular disease (CVD), and inflammation may contribute to this relationship. Pericardial fat, a highly metabolically active fat depot, is implicated in the pathogenesis of CVD, but its association with depressive symptoms is unclear. This study examined the cross-sectional and longitudinal association between depressive symptoms and pericardial fat over a three-year period. Participants were 543 healthy men and women (mean age = 62.9 years) without history or objective signs of coronary heart disease from the Whitehall II cohort. In men, depressive symptoms were positively associated with pericardial fat at baseline after adjustment for sociodemographics, waist to hip ratio and conventional cardiovascular risk factors. Inflammation, indexed by plasma interleukin 6 concentration, accounted for 17% of this association. Longitudinally, depressive symptoms did not predict pericardial fat three years later in men once baseline levels of pericardial fat were accounted for. No significant associations between depressive symptoms and pericardial fat were found in women. Overall, our findings suggest that greater pericardial fat might be a mechanism by which depressive symptoms are associated with increased risk for CVD in men, and inflammation may also lie on this pathway., (© 2022.

- Abstract
Introduction: Previous research suggests patients may be willing to communicate serious psychiatric concerns through patient portals. Methods: Retrospective chart review of portal messages sent by patients who had an emergency department (ED) visit or hospitalization for depression, self-harm, or suicidality or had a completed suicide (cases) was reviewed for content that was suggestive of depression or self-harm and language indicating emotional distress. Comparison with a randomly selected group (controls) was performed. Results: During the study period 420 messages were sent by 149 patients within 30 days of death by suicide, ED visit, and/or hospitalization related to depression, suicidality, or suicide attempt. Thirteen patients died by suicide but only 23% (3 of 13) sent one or more portal messages within 30 days before their death. None mentioned thoughts of self-harm. There were 271 messages sent by patients who were hospitalized, 142 messages by those who presented to the ED, and 56 messages patients who attempted suicide. Patient messages from cases were more likely than messages from controls to convey a depressed mood (17.1% vs. 3.1%, odds ratio 6.5; 95% confidence interval 3.6-11.9, p < 0.0001), thoughts of suicide or self-harm (4.8% vs. 0% p < 0.0001), or have a distressed tone (24.0% vs. 1.7%, odds ratio 18.7; 95% confidence interval 8.6-41, p < 0.0001). Conclusions: Patient portal messages from patients with subsequent hospitalizations for depression and suicidality do report thoughts of depression, distress, and thoughts of self-harm. However, portal use before completed suicide was not helpful at identifying at-risk patients although total numbers were small.

- Abstract
Objective: To survey barriers in prescribing naltrexone for alcohol use disorder., Methods: A 12-question survey related to naltrexone prescribing patterns, perceptions, and knowledge was sent to 770 prescribers in the departments of internal medicine, family medicine, and psychiatry across a health system with sites in Arizona, Florida, and Minnesota., Results: Responses were obtained and included for 146/770 prescribers (19.0% response rate). Most respondents were in the department of internal medicine ( n = 94, 64.4%), but the departments of psychiatry ( n = 22, 15.1%) and family medicine ( n = 30, 20.5%) were also represented. Only 34 (23.3%) respondents indicated they had prescribed naltrexone in the previous 3 months. The most common reasons for not prescribing naltrexone were "unfamiliarity with naltrexone for treatment of alcohol use disorder" and "patients do not have appropriate follow-up or are not in a formal treatment program." Compared with those representing internal/family medicine, psychiatry respondents were more likely to prescribe naltrexone and answer knowledge questions correctly., Conclusion: In this survey among primarily non-addiction-trained prescribers, a disparity was shown for prescribing naltrexone and in knowledge barriers between staff in internal/family medicine and psychiatry. There exist opportunities for education and quality improvement that promote the prescribing of naltrexone for alcohol use disorder by non-addiction specialists., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Leung, Narayanan, Markota, Miller, Philbrick, Burton and Kirchoff.)

- Abstract
Background: The number of pre-anesthetic medical evaluations (PAMEs) being conducted in primary care is increasing. Due to the COVID-19 pandemic, the use of telemedicine has surged, providing a feasible way to conduct some of these visits. This study aimed to identify patient-related factors where a face to face (FTF) evaluation is indicated, measured by the need for pre-operative testing., Methods: A retrospective chart review was conducted on patients age ≥ 18 years who had a PAME between January 2019-June 2020 at a rural primary care clinic in Southeast Minnesota. Data collected included age, gender, Charlson Comorbidity Index Score, medications, revised cardiac risk index (RCRI), smoking status, exercise capacity, body mass index, and pre-operative testing. Logistical regression modeling for odds ratios of outcomes was performed., Results: 254 patients were included, with an average age of 64.1 years; 43.7% were female. Most were obese (mean BMI 31.6), non-smoking (93.7%) with excellent functional capacity (87.8% ≥ 5 METs). 76.8% of the planned surgeries were intermediate or high risk. 35.0% ( n = 89) of visits resulted in medication adjustments and 76.7% ( n = 195) in pre-operative testing. Age ≥ 65 years, ≥7 current medications, and diabetes all significantly increased the odds of requiring pre-operative testing ( P < .05)., Conclusions: This study was able to identify patient-related factors that increased the likelihood of requiring pre-operative testing. Patients who are age ≥ 65 years, ≥7 current medications, and those with diabetes could be scheduled for a FTF evaluation. Others could be scheduled for a telemedicine visit to minimize health-care exposures., Competing Interests: Declaration of Conflicting Interests: The author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article., (© The Author(s) 2022.)

- Abstract
Background: The McIsaac criteria are a validated scoring system used to determine the likelihood of an acute sore throat being caused by group A streptococcus (GAS) to stratify patients who need strep testing., Objective: We aim to compare McIsaac criteria obtained during face-to-face (f2f) and non-f2f encounters., Methods: This retrospective study compared the percentage of positive GAS tests by McIsaac score for scores calculated during nurse protocol phone encounters, e-visits (electronic visits), and in person f2f clinic visits., Results: There was no difference in percentages of positive strep tests between encounter types for any of the McIsaac scores. There were significantly more phone and e-visit encounters with any missing score components compared with f2f visits. For individual score components, there were significantly fewer e-visits missing fever and cough information compared with phone encounters and f2f encounters. F2f encounters were significantly less likely to be missing descriptions of tonsils and lymphadenopathy compared with phone and e-visit encounters. McIsaac scores of 4 had positive GAS rates of 55% to 68% across encounter types. There were 4 encounters not missing any score components with a McIsaac score of 0. None of these 4 encounters had a positive GAS test., Conclusions: McIsaac scores of 4 collected during non-f2f care could be used to consider empiric treatment for GAS without testing if significant barriers to testing exist such as the COVID-19 pandemic or geographic barriers. Future studies should evaluate further whether non-f2f encounters with McIsaac scores of 0 can be safely excluded from GAS testing., (©Jennifer L Pecina, Leah M Nigon, Kristine S Penza, Martha A Murray, Beckie J Kronebusch, Nathaniel E Miller, Teresa B Jensen.

- Abstract
In this work, we present a Quantum Hopfield Associative Memory (QHAM) and demonstrate its capabilities in simulation and hardware using IBM Quantum Experience.. The QHAM is based on a quantum neuron design which can be utilized for many different machine learning applications and can be implemented on real quantum hardware without requiring mid-circuit measurement or reset operations. We analyze the accuracy of the neuron and the full QHAM considering hardware errors via simulation with hardware noise models as well as with implementation on the 15-qubit ibmq_16_melbourne device. The quantum neuron and the QHAM are shown to be resilient to noise and require low qubit overhead and gate complexity. We benchmark the QHAM by testing its effective memory capacity and demonstrate its capabilities in the NISQ-era of quantum hardware. This demonstration of the first functional QHAM to be implemented in NISQ-era quantum hardware is a significant step in machine learning at the leading edge of quantum computing., (© 2021.

- Abstract
Background: Gestational diabetes mellitus (GDM) affects nearly 5% of US pregnancies and is associated with poor outcomes. Perinatal depression is also associated with substantial risks to both the fetus and mother. There is limited data about the relationship between GDM and antenatal depression. Therefore, we looked at whether a GDM diagnosis would be associated with an increased risk of depression during pregnancy., Methods: We studied 562 pregnant women from 1 July 2013 to 30 June 2015, in a prospective multi-part survey on clinical obstetrical outcomes., Results: Of the 562 patients, 46 patients (8.0%) were diagnosed with GDM. There was no statistical difference between the groups for either history of prior or post-partum depression. Diagnosis of depression was present in 15.2% of the GDM group but only 6.2% of the control group. Regression modeling demonstrated an adjusted odds ratio (AOR) of 2.46 for a diagnosis of depression when the patient had a diagnosis of GDM (95% CI 1.01-6.03, p =.049)., Conclusions: The diagnosis of GDM was associated with an elevated risk of concomitant pregnancy diagnosis of depression. Given the elevated risk to patients diagnosed with GDM, a more frequent depression screening interval could be considered during the remainder of the pregnancy, such as each prenatal visit.

- Abstract
Objective: Patients with obesity may experience less patient-centered care. We assessed whether medical students' implicit/explicit weight-related attitudes and perceptions of normative attitudes are associated with patient-centered care for patients with obesity., Methods: Third and fourth year medical students (N = 111) at one medical school completed a survey and participated in a patient care scenario with a standardized patient with obesity. Encounters were coded for patient-centered behavior. Predictors of patient-centered behaviors were assessed., Results: Student perceptions that negative attitudes about patients with obesity are normative in medical school were significantly associated with poorer patient-centered behaviors, including lower attentiveness (b=-0.19, p = 0.01), friendliness (b=-0.28, p < 0.001), responsiveness (b=-0.21, p = 0.002), respectfulness (b=-0.17, p = 0.003), interactivity (b=-0.22, p = 0.003), likelihood of being recommended by observers (b=-0.34, p < 0.001), and patient-centeredness index scores (b=-0.16, p = 0.002). Student reported faculty role-modeling of discrimination against patients with obesity predicted lower friendliness (b=-0.16, p = 0.03), recommendation likelihood (b=-0.22, p = 0.04), and patient-centeredness index score (b=-0.12, p = 0.03)., Conclusions: Negative normative attitudes and behaviors regarding obesity in the medical school environment may adversely influence the quality of patient-centered behaviors provided to patients with obesity., Practice Implications: Efforts to improve patient-centered communication quality among medical trainees may benefit from intervention to improve group normative attitudes about patients with obesity., Competing Interests: Declaration of Competing Interest No conflicts of interest have been declared by the authors.

- Abstract
A healthy 33 year old male presented in December with a 3 week history of fever and fatigue. He had been deer-hunting in northern Minnesota 1 month prior and had sustained a tick bite. Extensive laboratory investigations and a lumbar puncture were conducted. He was empirically with doxycycline and had rapid improvement in his symptoms. Subsequently, PCR and serologic testing returned positive for Anaplasma phagocytophlium. Anaplasmosis is a tick-borne illness caused by the bacterium Anaplasma phagocytophilum and is typically seen in the warmer months. This patient's presentation in December was uncommon for a tick-borne illness in Minnesota. Regional weather records demonstrated unseasonably warm temperatures during the patient's trip. Ixodes ticks are known to be sensitive to temperature and humidity, which likely contributed to increased tick activity, leading to disease transmission. This case highlights the importance for clinicians to be aware of local weather patterns and how this might influence seasonal disease presentations.

- Abstract
A woman in her late fifties was admitted to the Family Medicine Inpatient Service directly from Rheumatology clinic for polyarticular pain and erythema with concern for infection. She was taking immunosuppressant medications for a history of multiple autoimmune diseases. Examination showed increasing erythema and tenderness on the upper and lower extremity joints. Histologic evaluation, surgical evaluation, and cultures were consistent with mycobacterium haemophilum infection. Mycobacterium haemophilum is an uncommon opportunistic infection that usually affects immunocompromised patients. The patient was treated with a multi-drug antibiotic regimen for several months due to drug resistance. Although this opportunistic infection is not common it should be considered in the differential of immunocompromised patients with skin and articular symptoms. Treatment outcomes are usually favorable if it caught earlier in the course.
