Following critical evaluation of the available literature to date, The International Society of Sports Nutrition (ISSN) position regarding caffeine intake is as follows: 1. Supplementation with caffeine has been shown to acutely enhance various aspects of exercise performance in many but not all studies. Small to moderate benefits of caffeine use include, but are not limited to: muscular endurance, movement velocity and muscular strength, sprinting, jumping, and throwing performance, as well as a wide range of aerobic and anaerobic sport-specific actions. 2. Aerobic endurance appears to be the form of exercise with the most consistent moderate-to-large benefits from caffeine use, …


A Solution For Breaking The Impasse Of Burnout Measurement, Renzo Bianchi, Irvin Sam Schonfeld Jan 2021

A Solution For Breaking The Impasse Of Burnout Measurement, Renzo Bianchi, Irvin Sam Schonfeld

Publications and Research

In view of the profound problems affecting burnout’s conceptualization and measurement and because there is now robust evidence that burnout is a depressive condition, we recommend that occupational health specialists shift their focus from burnout to depression. A measure of job-related depressive symptoms, the Occupational Depression Inventory (ODI), has recently been developed. Advantageously, the ODI resolves many of the persistent problems linked to burnout while being consistent with burnout researchers’ original aim of assessing a work-attributed form of distress. The ODI includes a diagnostic algorithm that allows investigators to estimate the prevalence of depressive disorders that individuals specifically ascribe to …


The Occupational Depression Inventory—A Solution For Estimating The Prevalence Of Job-Related Distress, Renzo Bianchi, Irvin Sam Schonfeld Jan 2021

The Occupational Depression Inventory—A Solution For Estimating The Prevalence Of Job-Related Distress, Renzo Bianchi, Irvin Sam Schonfeld

Publications and Research

We are concerned about researchers’ reliance on the burnout construct and the MBI-GS to estimate the prevalence of job-related distress. In this paper, we first describe some of the problems plaguing the burnout construct and its measures. Then, we present the Occupational Depression Inventory, a new instrument designed to help occupational health specialists get a clearer view of the mental health status of the workforce (Bianchi and Schonfeld, 2020).

In this study, the intervention was “scaled up” for delivery by local HIV care providers in real-world clinic settings. Methods Providers (N = 21) completed semi-structured interviews (N = 29) about their experiences with intervention scale-up. Rigorous thematic analyses were conducted within discussions of barriers and facilitators of intervention implementation. Results …


Are Covid-19 Vaccine Boosters Needed? The Science Behind Boosters, Rachel M. Burckhardt, John J. Dennehy, Leo L. M. Poon, Linda J. Saif, Lynn W. Enquist Jan 2021

Are Covid-19 Vaccine Boosters Needed? The Science Behind Boosters, Rachel M. Burckhardt, John J. Dennehy, Leo L. M. Poon, Linda J. Saif, Lynn W. Enquist

Publications and Research

Waning vaccine-induced immunity coupled with the emergence of SARS-CoV-2 variants has led to increases in breakthrough infections, prompting consideration for vaccine booster doses. Boosters have been reported to be safe and increase SARS-CoV-2-specific neutralizing antibody levels, but how these doses impact the trajectory of the global pandemic and herd immunity is unknown. Information on immunology, epidemiology and equitable vaccine distribution should be considered when deciding the timing and eligibility for COVID-19 vaccine boosters.


Binding Moral Values Gain Importance In The Presence Of Close Others, Daniel A. Yudkin, Ana P. Gantman, Wilhelm Hofmann, Jordi Quoidbach Jan 2021

Binding Moral Values Gain Importance In The Presence Of Close Others, Daniel A. Yudkin, Ana P. Gantman, Wilhelm Hofmann, Jordi Quoidbach

Publications and Research

A key function of morality is to regulate social behavior. Research suggests moral values may be divided into two types: binding values, which govern behavior in groups, and individualizing values, which promote personal rights and freedoms. Because people tend to mentally activate concepts in situations in which they may prove useful, the importance they afford moral values may vary according to whom they are with in the moment. In particular, because binding values help regulate communal behavior, people may afford these values more importance when in the presence of close (versus distant) others. Five studies test and support this hypothesis. …


Occupational Depression, Cognitive Performance, And Task Appreciation: A Study Based On Raven’S Advanced Progressive Matrices, Renzo Bianchi, Irvin Sam Schonfeld Jan 2021

Occupational Depression, Cognitive Performance, And Task Appreciation: A Study Based On Raven’S Advanced Progressive Matrices, Renzo Bianchi, Irvin Sam Schonfeld

Publications and Research

The Occupational Depression Inventory (ODI) was recently developed to assess depressive symptoms that individuals specifically attribute to their work. Research on the criterion validity of the instrument is still in its infancy. In this study, we examined whether the ODI predicted performance on, and appreciation of, a cognitively challenging test. In light of the link established between clinical depression and neuropsychological impairment, and considering that individuals with depressive symptoms are more likely to feel helpless under challenging circumstances, we hypothesized that occupational depression would be associated with poorer cognitive performance and a darkened appreciation of the task undertaken. We relied …


Assessment Challenges In Acquired Aphasia In Multilingual Individuals, Monica Norvik, Mira Goral Jan 2021

Assessment Challenges In Acquired Aphasia In Multilingual Individuals, Monica Norvik, Mira Goral

Publications and Research

Aphasia is an acquired language disorder resulting from damage to the brain, most typically a stroke in the left cerebral hemisphere. The degree and type of impairment vary depending on the site and size of the lesion, and the extent to which people with aphasia recover – with time and therapeutic intervention – their pre-stroke linguistic skills varies, depending on exogenous and endogenous variables. Multilingual speakers who acquire aphasia may exhibit comparable or different profiles of impairment in each of their languages. The present chapter explores the challenges associated with the assessment of all languages of multilingual and multicultural speakers …


Strengthening The Semantic Verb Network In Multilingual People With Aphasia: Within- And Cross-Language Treatment Effects, Aviva Lerman, Mira Goral, Lisa Edmonds, Loraine K. Obler Jan 2021

Strengthening The Semantic Verb Network In Multilingual People With Aphasia: Within- And Cross-Language Treatment Effects, Aviva Lerman, Mira Goral, Lisa Edmonds, Loraine K. Obler

Publications and Research

In multilingual people, semantic knowledge is predominantly shared across languages.
Providing semantic-focused treatment to people with aphasia has been posited to strengthen
connectivity within association cortices that subserve semantic knowledge. In multilingual people, such treatment should result in within- and cross-language generalisation to all languages, although not equally. We investigated treatment effects in two multilingual participants with aphasia who received verb-based semantic treatment in two pre-stroke highly
proficient languages. We compared within- and cross-language generalisation patterns across languages, finding within- and cross-language generalisation after treatment in the less-impaired, pre-morbidly more-proficient first-acquired language (L1). This observation supports the theory that connectivity …

Aphasia In Multilingual Patients, Mira Goral, Zahra Hejazi

Publications and Research

Purpose of Review

We summarize recent published work concerning assessment and treatment of aphasia in bilingual and multilingual people and review current related models of treatment outcomes. As well, we discuss studies that address the recently debated topic of cognitive processes in bilingual individuals with aphasia, with a focus on the effects of bilingualism on aphasia recovery and its potential protective effects.

Recent Findings

Providing assessment and treatment tools that best serve multilingual individuals with aphasia and unpacking the variables and mechanisms that underlie response to treatment have emerged as goals of several recent studies. Additionally, while findings are still …

The House Of Love And The Mental Hospital: Zones Of Care And Recovery In South India, Murphy Halliburton Jan 2021

The House Of Love And The Mental Hospital: Zones Of Care And Recovery In South India, Murphy Halliburton

Publications and Research

The Movement for Global Mental Health has defined the person suffering psychopathology in low-income countries as an abused and suffering subject in need of saving by biomedical psychiatry. Based on fieldwork in Kerala, South India, carried out at psychiatric clinics and a psychosocial rehabilitation centre, this paper examines patients’ experiences of illness, the degree and quality of family support, and attributions made to the role of ‘sneham’, or love, in recovery. The role of love and family involvement may help explain the provocative finding by WHO epidemiological studies that ‘developing’ countries – and India in particular – showed better rates …


Online Or In-Person? Examining College Decisions To Reopen During The Covid-19 Pandemic In Fall 2020, Jacob Felson, Amy Adamczyk Jan 2021

Online Or In-Person? Examining College Decisions To Reopen During The Covid-19 Pandemic In Fall 2020, Jacob Felson, Amy Adamczyk

Publications and Research

When coronavirus disease 2019 (COVID-19) became a major impediment to face-to-face college instruction in spring 2020, most teaching went online. Over the summer, colleges had to make difficult decisions about whether to return to in-person instruction. Although opening campuses could pose a major health risk, keeping instruction online could dissuade students from enrolling. Taking an ecological approach, the authors use mixed modeling techniques and data from 87 percent of two- and four-year public and four-year private U.S. colleges to assess the factors that shaped decisions about fall 2020 instructional modality. Most notably, the authors find that reopening decisions about whether …


Is Burnout A Depressive Condition? A 14-Sample Meta-Analytic And Bifactor Analytic Study, Renzo Bianchi, Jay Verkuilen, Irvin S. Schonfeld, Jari J. Hakanen, Markus Jansson-Fröjmark, Guadalupe Manzano-García, Eric Laurent, Laurenz L. Meier Jan 2021

Publications and Research

There is no consensus on whether burnout constitutes a depressive condition or an original entity requiring specific medical and legal recognition. In this study, we examined burnout–depression overlap using 14 samples of individuals from various countries and occupational domains (N = 12,417). Meta-analytically pooled disattenuated correlations indicated (a) that exhaustion—burnout’s core—is more closely associated with depressive symptoms than with the other putative dimensions of burnout (detachment and efficacy) and (b) that the exhaustion–depression association is problematically strong from a discriminant validity standpoint (r = .80). The overlap of burnout’s core dimension with depression was further illuminated in 14 exploratory structural …

Context

Standard pregnancy intentions measures do not always align with how people approach pregnancy. Studies that have investigated beyond a binary framework found that those with “ambivalent” feelings towards pregnancy are less likely to use contraception consistently, but the reasons for this are unclear. We sought to gain a nuanced understanding of pregnancy desires, and how perceptions about pregnancy are associated with contraceptive use.

Methods

We used non-probability quota sampling based on sex, age, and geographic region for a web-based survey of heterosexual men and women, aged 21–44 years, who could become pregnant/impregnate and were not currently pregnant (n = …

Age-related macular degeneration (AMD) is a leading cause of blindness worldwide. Drusen are key contributors to the etiology of AMD and the ability to modulate drusen biogenesis could lead to therapeutic strategies to slow or halt AMD progression. The mechanisms underlying drusen biogenesis, however, remain mostly unknown. Here we demonstrate that under homeostatic conditions extracellular vesicles (EVs) secreted by retinal pigment epithelium (RPE) cells are enriched in proteins associated with mechanisms involved in AMD pathophysiology, including oxidative stress, immune response, inflammation, complement system and drusen composition. Furthermore, we provide first evidence that drusen-associated proteins are released as cargo of extracellular …

The mechanisms underlying retinal development have not been completely elucidated. Extracellular vesicles (EVs) are novel essential mediators of cell‑to‑cell communication with emerging roles in developmental processes. Nevertheless, the identification of EVs in human retinal tissue, characterization of their cargo, and analysis of their potential role in retina development has not been accomplished. Three‑dimensional retinal tissue derived from human induced pluripotent stem cells (hiPSC) provide an ideal developmental system to achieve this goal. Here we report that hiPSC‑derived retinal organoids release exosomes and microvesicles with small noncoding RNA cargo. EV miRNA cargo‑predicted targetome correlates with Gene Ontology (GO) pathways involved in …


Feminist Abolitionist Nursing, Martha Paynter, Keisha Jefferies, Leah Carrier, Lorie Goshin Jan 2021

Feminist Abolitionist Nursing, Martha Paynter, Keisha Jefferies, Leah Carrier, Lorie Goshin

Publications and Research

The converging crises of COVID-19 and racist state violence in 2020 shifted public discourse about marginalization, public health, and racism in unprecedented ways. Nursing responded to the pandemic with heroic commitment and new politicization. But public engagement with systemic racism is forcing a reckoning in nursing. The profession has its own history of racism and of alliance with systems of state control with which to contend. In this article, we argue nursing must adopt an ethics of abolitionism to realize its goals for health and justice. Abolitionism theorizes that policing and prison systems, originating from systems of enslavement and colonial …


Expanding The Boundaries Of Food Policy: The Turn To Equity In New York City, Nevin Cohen, Rositsa Ilieva Dec 2020

Expanding The Boundaries Of Food Policy: The Turn To Equity In New York City, Nevin Cohen, Rositsa Ilieva

Publications and Research

Policymakers acknowledge that the food system is multidimensional and that social determinants affect diet-related health outcomes, yet cities have emphasized programs and policies narrowly connected to food access and nutritional health. Over the past fifteen years, the boundaries of food governance have expanded to include a wider range of issues and domains not previously considered within the purview of food policy, like labor, housing, and education policies. This paper illustrates the processes by which this shift occurs by presenting the case of New York City, which has broadened its food governance to a larger set of issues, requiring cross-sectoral initiatives …

Age and sex differences in brain metabolite concentrations in early life are not well under- stood. We examined the associations of age and sex with brain metabolite levels in healthy neonates, and investigated the associations between neonatal brain metabolite concentrations and developmental outcomes. Forty-one infants (36–42 gestational weeks at birth; 39% female) of predominantly Hispanic/Latina mothers (mean 18 years of age) underwent MRI scanning approximately two weeks after birth. Multiplanar chemical shift imaging was used to obtain voxel-wise maps of N-acetylaspartate (NAA), creatine, and choline concentrations across the brain. The Bayley Scales of Infant and Toddler Development, a measure of …


Africans Who Arrive In The United States Before 20 Years Of Age Maintain Both Cardiometabolic Health And Cultural Identity: Insight From The Africans In America Study, Elyssa M.

The overall consensus is that foreign-born adults who come to America age < 20 y achieve economic success but develop adverse behaviors (smoking and drinking) that lead to worse cardiometabolic health than immigrants who arrive age ≥ 20 y. Whether age of immigration affects the health of African-born Blacks living in America is unknown. Our goals were to examine cultural identity, behavior, and socioeconomic factors and determine if differences exist in the cardiometabolic health of Africans who immigrated to America before and after age 20 y. Of the 482 enrollees (age: 38 ± 1 (mean ± SE), range: 20–65 y) in the Africans in America cohort, 23% (111/482) arrived age < 20 y, and 77% (371/482) arrived age ≥ 20 y. Independent of francophone status or African region of origin, Africans who immigrated age < 20 y had similar or better cardiometabolic health than Africans who immigrated age ≥ 20 y. The majority of Africans who immigrated age < 20 y identified as African, had African-born spouses, exercised, did not adopt adverse health behaviors, and actualized early life migration advantages, such as an American university education. Due to maintenance of cultural identity and actualization of opportunities in America, cardiometabolic health may be protected in Africans who immigrate before age 20. In short, immigrant health research must be cognizant of the diversity within the foreign-born community and age of immigration.


Outlier Concepts Auditing Methodology For A Large Family Of Biomedical Ontologies, Ling Zheng, Hua Min, Yan Chen, Vipina Keloth, James Geller, Yehoshua Perl, George Hripcsak Dec 2020

Outlier Concepts Auditing Methodology For A Large Family Of Biomedical Ontologies, Ling Zheng, Hua Min, Yan Chen, Vipina Keloth, James Geller, Yehoshua Perl, George Hripcsak

Publications and Research

Background: Summarization networks are compact summaries of ontologies. The “Big Picture” view offered by summarization networks enables to identify sets of concepts that are more likely to have errors than control concepts. For ontologies that have outgoing lateral relationships, we have developed the "partial-area taxonomy" summarization network. Prior research has identified one kind of outlier concepts, concepts of small partials-areas within partial-area taxonomies. Previously we have shown that the small partial-area technique works successfully for four ontologies (or their hierarchies).

Methods: To improve the Quality Assurance (QA) scalability, a family-based QA framework, where one QA technique is potentially applicable to …

Missing Lateral Relationships In Top‑Level Concepts Of An Ontology, Ling Zheng, Yan Chen, Hua Min, P. Lloyd Hildebrand, Hao Liu, Michael Halper, James Geller, Sherri De Coronado, Yehoshua Perl

Publications and Research

Background: Ontologies house various kinds of domain knowledge in formal structures, primarily in the form of concepts and the associative relationships between them. Ontologies have become integral components of many health information processing environments. Hence, quality assurance of the conceptual content of any ontology is critical. Relationships are foundational to the definition of concepts. Missing relationship errors (i.e., unintended omissions of important definitional relationships) can have a deleterious effect on the quality of an ontology. An abstraction network is a structure that overlays an ontology and provides an alternate, summarization view of its contents. One kind of abstraction network is …

Elevated core temperature constitutes an important biomarker for COVID-19 infection; however, no standards currently exist to monitor fever using wearable peripheral temperature sensors. Evidence that sensors could be used to develop fever monitoring capabilities would enable large-scale health-monitoring research and provide high-temporal resolution data on fever responses across heterogeneous populations. We launched the TemPredict study in March of 2020 to capture continuous physiological data, including peripheral temperature, from a commercially available wearable device during the novel coronavirus pandemic. We coupled these data with symptom reports and COVID-19 diagnosis data. Here we report findings from the first 50 subjects who reported …

Publications and Research

Trypanosoma cruzi dysregulates the gene expression profile of primary human cardiomyocytes (PHCM) during the early phase of infection through a mechanism which remains to be elucidated. The role that small non-coding RNAs (sncRNA) including PIWI-interacting RNA (piRNA) play in regulating gene expression during the early phase of infection is unknown. To understand how T. cruzi dysregulate gene expression in the heart, we challenged PHCM with T. cruzi trypomastigotes and analyzed sncRNA, especially piRNA, by RNA-sequencing. The parasite induced significant differential expression of host piRNAs, which can target and regulate the genes which are important during the early infection phase. An …

Pandemic Vibrio Cholerae Shuts Down Site-Specific Recombination To Retain An Interbacterial Defence Mechanism, Francis J. Santoriello, Lina Michel, Daniel Unterweger, Stefan Pukatzki

Publications and Research

Vibrio cholerae is an aquatic microbe that can be divided into three subtypes: harmless environmental strains, localised pathogenic strains, and pandemic strains causing global cholera outbreaks. Each type has a contact-dependent type VI secretion system (T6SS) that kills neighbouring competitors by translocating unique toxic effector proteins. Pandemic isolates possess identical effectors, indicating that T6SS effectors may affect pandemicity. Here, we show that one of the T6SS gene clusters (Aux3) exists in two states: a mobile, prophage-like element in a small subset of environmental strains, and a truncated Aux3 unique to and conserved in pandemic isolates. Environmental Aux3 can be readily …
