Identification and Management of Thyroid Dysfunction Using At-Home Sample Collection and Telehealth Services: Retrospective Analysis of Real-World Data.

BACKGROUND: Programs aimed at modernizing thyroid care by pairing at-home sample collection methods with telehealth options may serve an important and emerging role in thyroid care. OBJECTIVE: The primary objective of this analysis was to evaluate telehealth use, demographics, and clinical characteristics of a cohort of consumer-initiated at-home laboratory thyroid test users who were also offered the option of follow-up telehealth consultations. METHODS: This was a retrospective analysis of real-world data from a deidentified consumer database of home-collected, mail-in thyroid tests used from March to May 2021 (N=8152). The mean age was 38.6 (range 18-85) years, and 86.6% (n=7061) of individuals identified as female. RESULTS: In total, 7% (n=587) of test takers fell into a thyroid dysfunction category (overt hypothyroidism: n=75, 0.9%; subclinical hypothyroidism: n=236, 2.9%; overt hyperthyroidism: n=5, 0.1%; and subclinical hyperthyroidism: n=271, 3.3%). Overall, 12% (n=984) of the overall sample opted into a telehealth consultation, with 91.8% (n=903) receiving a nontreatment telehealth consultation and 8.2% (n=81) receiving a treatment telemedicine consultation. Furthermore, 16% (n=96) of individuals with overt or subclinical thyroid dysfunction engaged in telehealth consultations. The majority of treatment consultations (59.3%, n=48) were conducted with people reporting a history of thyroid issues, with 55.6% (n=45) of people indicating wanting to discuss their current thyroid medication and 48% (n=39) receiving a prescription medication. CONCLUSIONS: The combination of at-home sample collection and telehealth is an innovative model for screening thyroid disorders, monitoring thyroid function, and increasing access to care, which can be implemented at a large scale and across a wide range of age groups.

New Opioid Analgesic Approvals and Outpatient Utilization of Opioid Analgesics in the United States, 1997 through 2015.

BACKGROUND: The opioid epidemic, driven in part by increased prescribing, is a public health emergency. This study examines dispensed prescription patterns and approvals of new opioid analgesic products to investigate whether the introduction of these new drugs increases prescribing. METHODS: Prescribing patterns based on dispensed prescription claims from the U.S. retail setting were assessed with new brand and generic opioid analgesic products approved in the United States from 1997 through 2015. RESULTS: From 1997 through 2015, the U.S. Food and Drug Administration (Silver Spring, Maryland) approved 263 opioid analgesic products, including 33 brand products. Dispensed prescriptions initially increased 80% from 145 million prescriptions in 1997 to a peak of 260 million prescriptions in 2012 before decreasing by 12% to 228 million prescriptions in 2015. Morphine milligram equivalents dispensed per prescription increased from 486 in 1997 to a peak of 950 in 2010, before decreasing to 905 in 2015. In 2015, generic products accounted for 96% (218/228 million prescriptions) of all opioid analgesic prescriptions dispensed. The remaining prescriptions were dispensed for brand products, of which nearly half were dispensed for one brand product (OxyContin, Purdue, USA). CONCLUSIONS: There has been a dramatic increase in prescriptions dispensed for opioid analgesics since 1997 and an increasing number of opioid analgesic approvals; however, the number of prescriptions dispensed has declined since 2012 despite an increasing number of approvals. Examination of dispensed prescriptions shows a shifting and complex market where multiple factors likely influence prescribing; the approval of new products alone may not be sufficient to be a primary driver of increased prescribing.

Transforming the endocrine consult: asynchronous provider consultations.

OBJECTIVE: To analyze the impact of virtual consultations on the spectrum and volume of endocrine consults, access to endocrine care, and downstream healthcare utilization. METHODS: A program (eConsults) designed to enable and reimburse asynchronous consultations between primary care physicians (PCPs) and specialists at the University of California, San Francisco, was launched in 2012. All eConsults (n = 158) submitted to endocrinology over the first year were analyzed for clinical focus and use of structured referral templates. PCP compliance with specialist recommendations was measured and stratified by provider type. Impact on endocrine referral volume was calculated using simple linear regression. Changes in wait times to endocrine care were analyzed comparing administrative data from the year of and the year prior to the introduction of eConsults. Downstream endocrine office visits, emergency department visits, and hospitalizations were captured by chart abstraction for all standard endocrine eConsults (n = 113). RESULTS: The proportion of endocrine referrals sent as eConsults (15 to 22%) was significantly higher than the combined average for all other participating specialties (7.4%) (P<.001). Overall, 76.0% of endocrinologist recommendations were fully implemented. There was no induced demand in total volume of referrals to endocrinology, and introduction of eConsults significantly improved access to endocrine care (odds ratio, 3.6; 95% confidence interval, 2.7 to 4.9). Rates of downstream healthcare utilization within 6 months of a completed eConsult were low. CONCLUSION: Use of virtual consultations in a fee-for-service, academic medical center setting significantly improved access to endocrine care and the quality of referrals. Increasing recognition and reimbursement of nontraditional consultation models will be essential to scaling and disseminating these programs.

Do Acoustic Characteristics of Dysarthria in People With Parkinson's Disease Differ Across Languages?

PURPOSE: Cross-language studies suggest more similarities than differences in how dysarthria affects the speech of people with Parkinson's disease (PwPD) who speak different languages. In this study, we aimed to identify the relative contribution of acoustic variables to distinguish PwPD from controls who spoke varieties of two Romance languages, French and Portuguese. METHOD: This bi-national, cross-sectional, and case-controlled study included 129 PwPD and 124 healthy controls who spoke French or Portuguese. All participants underwent the same clinical examinations, voice/speech recordings, and self-assessment questionnaires. PwPD were evaluated off and on optimal medication. Inferential analyses included Disease (controls vs. PwPD) and Language (French vs. Portuguese) as factors, and random decision forest algorithms identified relevant acoustic variables able to distinguish participants: (a) by language (French vs. Portuguese) and (b) by clinical status (PwPD on and off medication vs. controls). RESULTS: French-speaking and Portuguese-speaking individuals were distinguished from each other with over 90% accuracy by five acoustic variables (the mean fundamental frequency and the shimmer of the sustained vowel /a/ production, the oral diadochokinesis performance index, the relative sound level pressure and the relative sound pressure level standard deviation of the text reading). A distinct set of parameters discriminated between controls and PwPD: for men, maximum phonation time and the oral diadochokinesis speech proportion were the most significant variables; for women, variables calculated from the oral diadochokinesis were the most discriminative. CONCLUSIONS: Acoustic variables related to phonation and voice quality distinguished between speakers of the two languages. Variables related to pneumophonic coordination and articulation rate were the more effective in distinguishing PwPD from controls. Thus, our research findings support that respiration and diadochokinesis tasks appear to be the most appropriate to pinpoint signs of dysarthria, which are largely homogeneous and language-universal. In contrast, identifying language-specific variables with the speech tasks and acoustic variables studied was less conclusive.

Prospective clinical validation of the Empatica EmbracePlus wristband as a reflective pulse oximeter.

Introduction: Respiratory diseases such as chronic obstructive pulmonary disease, obstructive sleep apnea syndrome, and COVID-19 may cause a decrease in arterial oxygen saturation (SaO2). The continuous monitoring of oxygen levels may be beneficial for the early detection of hypoxemia and timely intervention. Wearable non-invasive pulse oximetry devices measuring peripheral oxygen saturation (SpO2) have been garnering increasing popularity. However, there is still a strong need for extended and robust clinical validation of such devices, especially to address topical concerns about disparities in performances across racial groups. This prospective clinical validation aimed to assess the accuracy of the reflective pulse oximeter function of the EmbracePlus wristband during a controlled hypoxia study in accordance with the ISO 80601-2-61:2017 standard and the Food & Drug Administration (FDA) guidance. Methods: Healthy adult participants were recruited in a controlled desaturation protocol to reproduce mild, moderate, and severe hypoxic conditions with SaO2 ranging from 100% to 70% (ClinicalTrials.gov registration #NCT04964609). The SpO2 level was estimated with an EmbracePlus device placed on the participant's wrist and the reference SaO2 was obtained from blood samples analyzed with a multiwavelength co-oximeter. Results: The controlled hypoxia study yielded 373 conclusive measurements on 15 subjects, including 30% of participants with dark skin pigmentation (V-VI on the Fitzpatrick scale). The accuracy root mean square (Arms) error was found to be 2.4%, within the 3.5% limit recommended by the FDA. A strong positive correlation between the wristband SpO2 and the reference SaO2 was observed (r = 0.96, P < 0.001), and a good concordance was found with Bland-Altman analysis (bias, 0.05%; standard deviation, 1.66; lower limit, -4.7%; and upper limit, 4.8%). Moreover, acceptable accuracy was observed when stratifying data points by skin pigmentation (Arms 2.2% in Fitzpatrick V-VI, 2.5% in Fitzpatrick I-IV), and sex (Arms 1.9% in females, and 2.9% in males). Discussion: This study demonstrates that the EmbracePlus wristband could be used to assess SpO2 with clinically acceptable accuracy under no-motion and high perfusion conditions for individuals of different ethnicities across the claimed range. This study paves the way for further accuracy evaluations on unhealthy subjects and during prolonged use in ambulatory settings.

Early Word Segmentation Behind the Mask.

Infants have been shown to rely both on auditory and visual cues when processing speech. We investigated the impact of COVID-related changes, in particular of face masks, in early word segmentation abilities. Following up on our previous study demonstrating that, by 4 months, infants already segmented targets presented auditorily at utterance-edge position, and, using the same visual familiarization paradigm, 7-9-month-old infants performed an auditory and an audiovisual word segmentation experiment in two conditions: without and with an FFP2 face mask. Analysis of acoustic and visual cues showed changes in face-masked speech affecting the amount, weight, and location of cues. Utterance-edge position displayed more salient cues than utterance-medial position, but the cues were attenuated in face-masked speech. Results revealed no evidence for segmentation, not even at edge position, regardless of mask condition and auditory or visual speech presentation. However, in the audiovisual experiment, infants attended more to the screen during the test trials when familiarized with without mask speech. Also, the infants attended more to the mouth and less to the eyes in without mask than with mask. In addition, evidence for an advantage of the utterance-edge position in emerging segmentation abilities was found. Thus, audiovisual information provided some support to developing word segmentation. We compared 7-9-monthers segmentation ability observed in the Butler and Frota pre-COVID study with the current auditory without mask data. Mean looking time for edge was significantly higher than unfamiliar in the pre-COVID study only. Measures of cognitive and language development obtained with the CSBS scales showed that the infants of the current study scored significantly lower than the same-age infants from the CSBS (pre-COVID) normative data. Our results suggest an overall effect of the pandemic on early segmentation abilities and language development, calling for longitudinal studies to determine how development proceeds.

The Role of Pseudocereals in Celiac Disease: Reducing Nutritional Deficiencies to Improve Well-Being and Health.

Celiac disease or gluten-dependent enteropathy is a chronic autoimmune pathology triggered by dietary gluten in genetic predisposed individuals, mediated by transglutaminase 2 IgA autoantibodies and associated with a deteriorating immune and inflammatory response. This leads to intestinal villous atrophy, impairing the intestinal mucosa structure and function of secretion, digestion, and absorption. The result is macro- and micronutrient deficiency, including fat soluble vitamins and minerals, and a consequent nutritional status depletion. A lifelong gluten-free diet is the only available treatment for celiac patients in order to assure normal intestinal mucosa and remission of gastrointestinal symptoms. However, a gluten-free diet can itself cause other nutritional deficiencies due to its restrictive nature regarding gluten-containing cereals. A group of gluten-free cereals, known as pseudocereals, is increasingly recognized as valuable options for gluten-free diets due to their high nutritional value. Amaranth, quinoa, millet, and buckwheat are examples of gluten-free nutrient-dense grains that can be used as alternatives to the conventional gluten-containing grains and improve the variety and nutritional quality of the celiac diet. Current work reviews the nutritional pitfalls of a gluten-free diet and analyses how pseudocereals can contribute to revert those deficiencies and optimize the nutritional value of this mandatory diet for the celiac population.

Early Visual Attention Abilities and Audiovisual Speech Processing in 5-7 Month-Old Down Syndrome and Typically Developing Infants.

Communicative abilities in infants with Down syndrome (DS) are delayed in comparison to typically developing (TD) infants, possibly affecting language development in DS. Little is known about what abilities might underlie poor communication and language skills in DS, such as visual attention and audiovisual speech processing. This study compares DS and TD infants between 5-7 months of age in a visual orientation task, and an audiovisual speech processing task, which assessed infants' looking pattern to communicative cues (i.e., face, eyes, mouth, and waving arm). Concurrent communicative abilities were also assessed via the CSBS-DP checklist. We observed that DS infants orient their visual attention slower than TD infants. Both groups attended more to the eyes than the mouth, and more to the face than the waving arm. However, DS infants attended less to the eyes than the background, and equally to the face and the background, suggesting their difficulty to assess linguistically relevant cues. Finally, communicative skills were related to attention to the eyes in TD, but not in DS infants. Our study showed that early attentional and audiovisual abilities are impaired in DS infants, and might underlie their communication skills, suggesting that early interventions in this population should emphasize those skills.

(Dys)Prosody in Parkinson's Disease: Effects of Medication and Disease Duration on Intonation and Prosodic Phrasing.

The phonology of prosody has received little attention in studies of motor speech disorders. The present study investigates the phonology of intonation (nuclear contours) and speech chunking (prosodic phrasing) in Parkinson's disease (PD) as a function of medication intake and duration of the disease. Following methods of the prosodic and intonational phonology frameworks, we examined the ability of 30 PD patients to use intonation categories and prosodic phrasing structures in ways similar to 20 healthy controls to convey similar meanings. Speech data from PD patients were collected before and after a dopaminomimetic drug intake and were phonologically analyzed in relation to nuclear contours and intonational phrasing. Besides medication, disease duration and the presence of motor fluctuations were also factors included in the analyses. Overall, PD patients showed a decreased ability to use nuclear contours and prosodic phrasing. Medication improved intonation regardless of disease duration but did not help with dysprosodic phrasing. In turn, disease duration and motor fluctuations affected phrasing patterns but had no impact on intonation. Our study demonstrated that the phonology of prosody is impaired in PD, and prosodic categories and structures may be differently affected, with implications for the understanding of PD neurophysiology and therapy.

Digital Diabetes Congress 2019.

New applications of digital health software and sensors for diabetes are rapidly becoming available. The link between healthcare, wearable or carryable devices, and the use of smartphones is increasingly being used by patients for timely information and by healthcare professionals to deliver information and personalized advice and to encourage healthy behavior. To assemble stakeholders from academia, industry, and government, Diabetes Technology Society and Sansum Diabetes Research Institute hosted the 3rd Annual Digital Diabetes Congress on May 14-15, 2019 in San Francisco. Physicians, entrepreneurs, attorneys, psychologists, and other leaders in the diabetes technology field came together to discuss current and future trends and applications of digital tools in diabetes. The meeting focused on eight topics: 1) User Interface/User Experience (UI/UX) for Digital Health, 2) clinical aspects, 3) marketing, 4) investment, 5) regulation, 6) who owns the data, 7) engagement, and 8) the future of digital health. This meeting report contains summaries of the meeting's eight plenary sessions and eight panel discussions, which were all focused on an important aspect of the development, use, and regulation of diabetes digital tools.

A Road Map for Translational Research on Artificial Intelligence in Medical Imaging: From the 2018 National Institutes of Health/RSNA/ACR/The Academy Workshop.

Advances in machine learning in medical imaging are occurring at a rapid pace in research laboratories both at academic institutions and in industry. Important artificial intelligence (AI) tools for diagnostic imaging include algorithms for disease detection and classification, image optimization, radiation reduction, and workflow enhancement. Although advances in foundational research are occurring rapidly, translation to routine clinical practice has been slower. In August 2018, the National Institutes of Health assembled multiple relevant stakeholders at a public meeting to discuss the current state of knowledge, infrastructure gaps, and challenges to wider implementation. The conclusions of that meeting are summarized in two publications that identify and prioritize initiatives to accelerate foundational and translational research in AI for medical imaging. This publication summarizes key priorities for translational research developed at the workshop including: (1) creating structured AI use cases, defining and highlighting clinical challenges potentially solvable by AI; (2) establishing methods to encourage data sharing for training and testing AI algorithms to promote generalizability to widespread clinical practice and mitigate unintended bias; (3) establishing tools for validation and performance monitoring of AI algorithms to facilitate regulatory approval; and (4) developing standards and common data elements for seamless integration of AI tools into existing clinical workflows. An important goal of the resulting road map is to grow an ecosystem, facilitated by professional societies, industry, and government agencies, that will allow robust collaborations between practicing clinicians and AI researchers to advance foundational and translational research relevant to medical imaging.

State naloxone access laws are associated with an increase in the number of naloxone prescriptions dispensed in retail pharmacies.

BACKGROUND: In response to the ongoing opioid overdose epidemic, many states have enacted laws increasing naloxone access by lay people, such as friends and family members of people who use drugs (PWUD), as well as PWUD themselves. METHOD: We utilized Symphony Health Solutions' PHAST Prescription data from 2007 to 2016 to investigate whether naloxone access laws were associated with an increase in naloxone dispensed from retail pharmacies in the United States. RESULT: Using a negative binomial regression, we found that naloxone access laws were associated with an average increase of 78 prescriptions dispensed per state per quarter. This represents an average 79% increase in naloxone dispensed from U.S. retail pharmacies, compared with states where there were no such laws. CONCLUSION: Our study suggests that naloxone access laws can increase the availability and accessibility of naloxone.

Analysis of an electronic consultation program at an academic medical centre: Primary care provider questions, specialist responses, and primary care provider actions.

Introduction Electronic consultations (eConsults) increase access to specialty care, but little is known about the types of questions primary care providers (PCPs) ask through eConsults, and how they respond to specialist recommendations. Methods This is a retrospective descriptive analysis of the first 200 eConsults completed in the UCSF eConsult program. Participating PCPs were from eight adult primary care sites at the University of California, San Francisco (UCSF), USA. Medicine subspecialties participating were Cardiology, Endocrinology, Gastroenterology/hepatology, Hematology, Infectious diseases, Nephrology, Pulmonary medicine, Rheumatology, and Sleep medicine. We categorized eConsult questions into "diagnosis," "treatment," and/or "monitoring." We performed medical record reviews to determine the percentage of specialist recommendations PCPs implemented, and the proportion of patients with a specialist visit in the same specialty as the eConsult, emergency department visit, or hospital admission during the subsequent six months. Results PCP questions related to diagnosis in 71% of cases, treatment in 46%, and monitoring in 21%. Specialist responses related to diagnosis in 76% of cases, treatment in 64%, and monitoring in 40%. PCPs ordered 79% of all recommended laboratory tests, 86% of recommended imaging tests and procedures, 65% of recommended new medications, and 73% of recommended medication changes. In the six months after the eConsult, 14% of patients had a specialist visit within the UCSF system in the same specialty as the eConsult. Discussion eConsults provide guidance to PCPs across the spectrum of patient care. PCPs implement specialists' recommendations in the large majority of cases, and few patients subsequently require in-person specialty care related to the reason for the eConsult.

Palliative care and the Portuguese health system.

We are currently witnessing the decline of acute diseases and the emergence of chronic degenerative diseases. In Portugal, the cumulative effect of the reduction in mortality and birth rates has resulted in an ageing population. The ageing population will create in the medium term a new dynamic of recruitment in various sectors, including health. With increased life expectancy, the care of chronically ill has become an important area in the context of health services, since they need to be increasingly more focused on the need to provide palliative rather than curative care. Rationalization of resources must be a goal so that waste is minimized. The present model of palliative care ceases to respond to the pressing needs. What to do, to adapt to the changes brought by demographic change and by innovation? What models should be adopted for better resource optimization in palliative care? A literature review was carried out, including articles that compared the main differences between hospital and home care. Portugal has a multi-sectoral palliative care model, in light of what happens in reference countries, however, a better rationalization of resources will be required in order to ensure optimization in the distribution of patients. We also conclude that there is a gap between the patient's will and what is recommended. To respect the individual preferences of the patient, it is necessary to develop quality home-based palliative care services, focusing on training and the expansion of field teams.

Dysarthria in individuals with Parkinson's disease: a protocol for a binational, cross-sectional, case-controlled study in French and European Portuguese (FraLusoPark).

INTRODUCTION: Individuals with Parkinson's disease (PD) have to deal with several aspects of voice and speech decline and thus alteration of communication ability during the course of the disease. Among these communication impairments, 3 major challenges include: (1) dysarthria, consisting of orofacial motor dysfunction and dysprosody, which is linked to the neurodegenerative processes; (2) effects of the pharmacological treatment, which vary according to the disease stage; and (3) particular speech modifications that may be language-specific, that is, dependent on the language spoken by the patients. The main objective of the FraLusoPark project is to provide a thorough evaluation of changes in PD speech as a result of pharmacological treatment and disease duration in 2 different languages (French vs European Portuguese). METHODS AND ANALYSIS: Individuals with PD are enrolled in the study in France (N=60) and Portugal (N=60). Their global motor disability and orofacial motor functions is assessed with specific clinical rating scales, without (OFF) and with (ON) pharmacological treatment. 2 groups of 60 healthy age-matched volunteers provide the reference for between-group comparisons. Along with the clinical examinations, several speech tasks are recorded to obtain acoustic and perceptual measures. Patient-reported outcome measures are used to assess the psychosocial impact of dysarthria on quality of life. ETHICS AND DISSEMINATION: The study has been approved by the local responsible committees on human experimentation and is conducted in accordance with the ethical standards. A valuable large-scale database of speech recordings and metadata from patients with PD in France and Portugal will be constructed. Results will be disseminated in several articles in peer-reviewed journals and in conference presentations. Recommendations on how to assess speech and voice disorders in individuals with PD to monitor the progression and management of symptoms will be provided. TRIAL REGISTRATION NUMBER: NCT02753192, Pre-results.

Effect of oral hygiene and 0.12% chlorhexidine gluconate oral rinse in preventing ventilator-associated pneumonia after cardiovascular surgery.

BACKGROUND: Ventilator-associated pneumonia (VAP) is a nosocomial infection of multifactorial etiology and has a negative influence on cardiovascular surgery (CVS) outcomes. OBJECTIVES: Determine the effect of toothbrushing plus 0.12% chlorhexidine gluconate oral rinse in preventing VAP after CVS. METHODS: In a quasi-experimental study, patients undergoing heart surgery were enrolled in a protocol for controlling dental biofilm by proper oral hygiene (toothbrushing) and oral rinses with 0.12% chlorhexidine gluconate (Group 1), and they were compared with a historical control group (Group 2), which included patients who underwent cardiac surgery between 2009 and 2010 and who received regular oral hygiene care. Seventy-two hours before surgery, a dentist provided instruction and supervised oral hygiene with toothbrushing and chlorhexidine oral rinses to patients in Group 1. RESULTS: Each group comprised 150 patients. A lower incidence of VAP (2.7% [95% CI 0.7-7.8] vs 8.7% [95% CI 4.9-14.7], P = .04) and a shorter hospital stay (9 ± 3 d [95% CI 8.5-9.5] vs 10 ± 4 d [95% CI 9.4-10.7], P = .01) were observed in Group 1. No significant differences in all-cause in-hospital death were observed between groups (5.3% vs 4.7%, P > .99). The risk for developing pneumonia after surgery was 3-fold higher in Group 2 (3.9, 95% CI 1.1-14.2). CONCLUSIONS: Oral hygiene and mouth rinses with chlorhexidine under supervision of a dentist proved effective in reducing the incidence of VAP.
