Investigating brain dynamics and their association with cognitive control in opioid use disorder using naturalistic and drug cue paradigms.

Objectives: Opioid use disorder (OUD) impacts millions of people worldwide. The prevalence and debilitating effects of OUD present a pressing need to understand its neural mechanisms to provide more targeted interventions. Prior studies have linked altered functioning in large-scale brain networks with clinical symptoms and outcomes in OUD. However, these investigations often do not consider how brain responses change over time. Time-varying brain network engagement can convey clinically relevant information not captured by static brain measures. Methods: We investigated brain dynamic alterations in individuals with OUD by applying a new multivariate computational framework to movie-watching (i.e., naturalistic; N=76) and task-based (N=70) fMRI. We further probed the associations between cognitive control and brain dynamics during a separate drug cue paradigm in individuals with OUD. Results: Compared to healthy controls (N=97), individuals with OUD showed decreased variability in the engagement of recurring brain states during movie-watching. We also found that worse cognitive control was linked to decreased variability during the rest period when no opioid-related stimuli were present. Conclusions: These findings suggest that individuals with OUD may experience greater difficulty in effectively engaging brain networks in response to evolving internal or external demands. Such inflexibility may contribute to aberrant response inhibition and biased attention toward opioid-related stimuli, two hallmark characteristics of OUD. By incorporating temporal information, the current study introduces novel information about how brain dynamics are altered in individuals with OUD and their behavioral implications.

A Quantitative Examination of Illness Models Among People With Opioid Use Disorder Receiving Methadone Treatment.

BACKGROUND: Few studies have examined illness models among people with addiction. We investigated illness models and their associations with demographics and treatment beliefs among patients receiving methadone treatment for opioid use disorder. METHODS: From January 2019 to February 2020, patients receiving methadone treatment at outpatient opioid treatment programs provided demographics and rated using 1 to 7 Likert-type scales agreement with addiction illness models (brain disease model, chronic medical condition model [CMCM], and no explanation [NEM]) and treatment beliefs. Pairwise comparisons and multivariate regressions were used to examine associations between illness models, demographics, and treatment beliefs. Statistical significance was set at P < 0.05. RESULTS: A total of 450 patients participated in the study. Forty percent self-identified as female, 13% as Hispanic, and 78% as White; mean age was 38.5 years. Brain disease model was the most frequently endorsed illness model (46.2%), followed by CMCM (41.7%) and NEM (21.9%). In multivariate analyses, agreement with brain disease model was significantly positively associated with beliefs that methadone treatment would be effective, counseling is important, and methadone is lifesaving, whereas agreement with CMCM was significantly positively associated with beliefs that methadone treatment would be effective, counseling is important, 12-step is the best treatment, taking methadone daily is important, and methadone is lifesaving. In multivariate analyses, agreement with NEM was negatively significantly associated with beliefs that methadone would be effective, counseling is important, taking methadone daily is important, and methadone is lifesaving. DISCUSSION: Many patients in methadone treatment endorsed medicalized addiction models. Agreement with addiction illness models appear to be related to treatment beliefs.

The sleep justice study - a prospective cohort study assessing sleep as a cardiometabolic risk factor after incarceration: a protocol paper.

BACKGROUND: An estimated 11 million individuals are released from U.S. jails and prisons each year. Individuals with a history of incarceration have higher rates of cardiovascular disease (CVD) events and mortality compared to the general population, especially in the weeks following release from carceral facilities. Healthy sleep, associated with cardiovascular health, is an underexplored factor in the epidemiology of CVD in this population. Incarcerated people may have unique individual, environmental, and institutional policy-level reasons for being sleep deficient. The social and physical environment within carceral facilities and post-release housing may synergistically affect sleep, creating disparities in sleep and cardiovascular health. Since carceral facilities disproportionately house poor and minoritized groups, population-specific risk factors that impact sleep may also contribute to inequities in cardiovascular outcomes. METHODS: This study is ancillary to an ongoing prospective cohort recruiting 500 individuals with known cardiovascular risk factors within three months of release from incarceration, the Justice-Involved Individuals Cardiovascular Disease Epidemiology (JUSTICE) study. The Sleep Justice study will measure sleep health among participants at baseline and six months using three validated surveys: the Pittsburgh Sleep Quality Index (PSQI), the STOP-Bang, and the Brief Index of Sleep Control. In a subsample of 100 individuals, we will assess sleep over the course of one week using wrist actigraphy, a validated objective measure of sleep that collects data on rest-activity patterns, sleep, and ambient light levels. Using this data, we will estimate and compare sleep health and its association with CVD risk factor control in individuals recently released from carceral facilities. DISCUSSION: The incarceration of millions of poor and minoritized groups presents an urgent need to understand how incarceration affects CVD epidemiology. This study will improve our understanding of sleep health among people released from carceral facilities and its potential relationship to CVD risk factor control. Using subjective and objective measures of sleep will allow us to identify unique targets to improve sleep health and mitigate cardiovascular risk in an otherwise understudied population.

Prenatal Care Experiences of Childbearing People With Disabilities in Ontario, Canada.

OBJECTIVE: To explore the care experiences of childbearing people with physical, sensory, and/or intellectual/developmental disabilities during pregnancy. DESIGN: Descriptive qualitative. SETTING: Ontario, Canada, where physician and midwifery care during pregnancy are provided at no direct cost to residents. PARTICIPANTS: Thirty-one people with physical, sensory, and/or intellectual/developmental disabilities (who self-identified as cisgender women [n = 29] and trans or nonbinary persons [n = 2]) who gave birth in the last 5 years. METHODS: We recruited childbearing people with disabilities through disability and parenting organizations, social media, and our team's networks. Using a semistructured guide, we conducted in-person and virtual (e.g., telephone or Zoom) interviews with childbearing people with disabilities in 2019 to 2020. We asked participants about the services they accessed during pregnancy and if services met their needs. We used a reflexive thematic analysis approach to analyze interview data. RESULTS: Across disability groups, we identified four common themes: Unmet Accommodation Needs, Lack of Coordinated Care, Ableism, and Advocacy as a Critical Resource. We found that these experiences manifested in unique ways based on disability type. CONCLUSION: Our findings suggest the need for accessible, coordinated, and respectful prenatal care for people with disabilities, with the requirements of such care depending on the needs of the individual person with a disability. Nurses can play a key role in identifying the needs and supporting people with disabilities during pregnancy. Education and training for nurses, midwives, obstetricians, and other prenatal care providers should focus on disability-related knowledge and respectful prenatal care.

Anti-corruption in global health systems: using key informant interviews to explore anti-corruption, accountability and transparency in international health organisations.

OBJECTIVES: Corruption undermines the quality of healthcare and leads to inequitable access to essential health products. WHO, Global Fund, United Nations Development Programme (UNDP) and World Bank are engaged in anti-corruption in health sectors globally. Throughout the COVID-19 pandemic, weakened health systems and overlooked regulatory processes have increased corruption risks. The objective of this study is thus to explore the strengths and weaknesses of these organisations' anti-corruption mechanisms and their trajectories since the pandemic began. DESIGN, SETTING AND PARTICIPANTS: 25 semistructured key informant interviews with a total of 27 participants were conducted via Zoom between April and July 2021 with informants from WHO, World Bank, Global Fund and UNDP, other non-governmental organisations involved in anti-corruption and academic institutions. Key informant selection was guided by purposive and snowball sampling. Detailed interview notes were qualitatively coded by three researchers. Data analysis followed an inductive-deductive hybrid thematic analysis framework. RESULTS: The findings demonstrate that WHO, World Bank, Global Fund and UNDP have shifted from criminalisation/punitive approaches to anti-corruption to preventative ones and that anti-corruption initiatives are strong when they are well funded, explicitly address corruption and are complemented by strong monitoring and evaluation mechanisms. Weaknesses in the organisations' approaches to anti-corruption include one-size-fits-all approaches, lack of political will to address corruption and zero-tolerance policies for corruption. The COVID-19 pandemic has highlighted the necessity of improving anti-corruption by promoting strong accountability and transparency in health systems. CONCLUSIONS: Results from this study highlight the strengths, weaknesses and recent trajectories of anti-corruption in the Global Fund, World Bank, UNDP and WHO. This study underscores the importance of implementing strong and robust anti-corruption mechanisms specifically geared towards corruption prevention that remain resilient even in times of emergency.

An exploration of anti-corruption and health in international organizations.

Corruption is a global wicked problem that threatens the achievement of health, social and economic development goals, including Sustainable Development Goal # 3: Ensuring healthy lives and promoting well-being for all. The COVID-19 pandemic and its resulting strain on health systems has heightened risks of corruption both generally and specifically within health systems. Over the past years, international organizations, including those instrumental to the global COVID-19 response, have increased efforts to address corruption within their operations and related programs. However, as attention to anti-corruption efforts is relatively recent within international organizations, there is a lack of literature examining how these organizations address corruption and the impact of their anti-corruption efforts. This study addresses this gap by examining how accountability, transparency, and anti-corruption are taken up by international organizations within their own operations and the reported outcomes of such efforts. The following international organizations were selected as the focus of this document analysis: the World Health Organization, the Global Fund, the United Nations Development Programme, and the World Bank Group. Documents were identified through a targeted search of each organization's website. Documents were then analyzed combining elements of content analysis and thematic analysis. The findings demonstrate that accountability and transparency mechanisms have been employed by each of the four international organizations to address corruption. Further, these organizations commonly employed oversight mechanisms, including risk assessments, investigations, and audits to monitor their internal and external operations for fraud and corruption. All organizations used sanction strategies meant to reprimand identified transgressors and deter future corruption. Findings also demonstrate a marked increase in anti-corruption efforts by these international organizations in recent years. Though this is promising, there remains a distinct absence of evidence demonstrating the impact of such efforts on the prevalence and severity of corruption in international organizations.

A systematic review of digital technology and innovation and its potential to address anti-corruption, transparency, and accountability in the pharmaceutical supply chain.

INTRODUCTION: The urgent need to acquire medical supplies amidst the COVID-19 pandemic has led to bypassing of controls that govern the global pharmaceutical supply chain, increasing the risk of corruption. Hence, promoting anti-corruption, transparency, and accountability (ACTA) in supply chain and procurement has never been more important. The adoption of digital tools, if designed and implemented appropriately, can reduce the risks of corruption. AREAS COVERED: Following PRISMA guidelines, we conducted an interdisciplinary systematic review of health/medicine, humanities/social sciences, engineering, and computer science literature, with the aims of identifying technologies used for pharmaceutical supply chain and procurement optimization and reviewing whether they address ACTA mechanisms to strengthen pharmaceutical governance. Our review identified four distinct categories of digital solutions: e-procurement and open contracting; track-and-trace technology; anti-counterfeiting technology; and blockchain technology. EXPERT OPINION: Findings demonstrate an increase in research of technologies to improve pharmaceutical supply chain and procurement functions; however, most technologies are not being leveraged to directly address ACTA or global health outcomes. Some blockchain and RFID technologies incorporated ACTA mechanisms and mentioned specific policy/governance frameworks, but more purposeful linkage is needed. Findings point to the need for targeted policy development and governance to activate these innovative technologies to improve global health .

Barriers to and facilitators of effective communication in perinatal care: a qualitative study of the experiences of birthing people with sensory, intellectual, and/or developmental disabilities.

BACKGROUND: Effective provider-patient communication is a key element of quality health care, including perinatal care. What constitutes "effective communication" in perinatal care may vary according to the population seeking care, such as women with intellectual and developmental disabilities (IDD) and sensory disabilities. Research broadly indicates that communication issues are among the barriers to perinatal care experienced by women with disabilities. However, few studies have explicitly explored their communication experiences in this context. The purpose of this study was to understand the communication experiences of birthing people with IDD and/or sensory disabilities in perinatal care. METHODS: We conducted semi-structured interviews with 17 people with IDD (e.g., autism, cognitive delay) and/or sensory disabilities (e.g., d/Deaf, blind) in Ontario, Canada, who had recently given birth, to explore barriers to and facilitators of effective communication in perinatal care. A combination of deductive and inductive thematic analysis guided data analysis. RESULTS: We found that birthing people with IDD and/or sensory disabilities encountered multiple barriers to effective communication in perinatal care, namely, lack of policies and guidelines, lack of provider experience, lack of provider effort, as well as ableism and provider assumptions. Facilitators included knowledgeable, aware, and supportive providers; access to communication aids and services; tailoring information to patients' disability-related communication needs; empathic communication; and, communication among providers. CONCLUSION: Unmet communication needs may contribute to negative health and social outcomes for birthing people with disabilities and their newborns. Accessibility policy implementation and practice change are needed to meet the communication needs of people with IDD and/or sensory disabilities in perinatal care to ensure positive experiences and outcomes.

Cardiometabolic disorders, inflammation and the incidence of non-alcoholic fatty liver disease: A longitudinal study comparing lean and non-lean individuals.

BACKGROUND: There is limited knowledge about the risk of non-alcoholic fatty liver disease (NAFLD) associated with cardiometabolic disorders in lean persons. This study examines the contribution of cardiometabolic disorders to NAFLD risk among lean individuals and compares to non-lean individuals. METHODS: We analyzed longitudinal data from 6,513 participants of a yearly voluntary routine health testing conducted at the Hospital Israelita Albert Einstein, Brazil. NAFLD was defined as hepatic ultrasound diagnosed fatty liver in individuals scoring below 8 on the alcohol use disorders identification test. Our main exposure variables were elevated blood glucose, elevated blood pressure (BP), presence of atherogenic dyslipidemia (AD, defined as the combination of elevated triglycerides and low HDL cholesterol) and physical inactivity (<150 minutes/week of moderate activity). We further assessed the risk of NAFLD with elevations in waist circumference and high sensitivity C-reactive protein (HsCRP). RESULTS: Over 15,580 person-years (PY) of follow-up, the incidence rate of NAFLD was 7.7 per 100 PY. In multivariate analysis adjusting for likely confounders, AD was associated with a 72% greater risk of NAFLD (IRR: 1.72 [95% CI:1.32-2.23]). Elevated blood glucose (IRR: 1.71 [95%CI: 1.29-2.28]) and physical inactivity (IRR: 1.46 [95%CI: 1.28-1.66]) were also independently associated with increased risk of NAFLD. In lean individuals, AD, elevated blood glucose and elevated BP were significantly associated with NAFLD although for elevated blood glucose, statistical significance was lost after adjusting for possible confounders. Physical inactivity and elevations in HsCRP were not associated with the risk of NAFLD in lean individuals only. Among lean (and non-lean) individuals, there was an independent association between progressively increasing waist circumference and NAFLD. CONCLUSION: Cardiometabolic risk factors are independently associated with NAFLD. However, there are significant differences in the metabolic risk predictors of NAFLD between lean and non-lean individuals. Personalized cardiovascular disease risk stratification and appropriate preventive measures should be considered in both lean and non-lean individuals to prevent the development of NAFLD.

Differences in Symptoms and Severity of Obstructive Sleep Apnea between Black and White Patients.

Rationale: Prior work suggests that Black patients have more severe obstructive sleep apnea (OSA) upon clinical presentation. However, the extent to which this may reflect differences in symptoms or other standard measures of OSA risk is unclear. Objectives: We assessed for racial disparities in OSA characteristics at time of initial clinical diagnosis. Methods: Data from 890 newly diagnosed patients with OSA at an urban academic sleep center were included in this analysis. All patients completed a standardized questionnaire on demographics and sleep-related symptoms and underwent laboratory polysomnography. Symptom severity at the time of evaluation was compared across race and sex. Results: Black men were underrepresented in the sleep lab, making up only 15.8% of the cohort and 31.3% of Black participants (P < 0.001). Despite this, Black men had the most severe OSA with a mean apnea hypopnea index of 52.4 ± 39.4 events/hour, compared with 39.0 ± 28.9 in White men, 33.4 ± 32.3 in Black women, and 26.2 ± 23.8 in White women (P < 0.001 for test of homogeneity). Black men also had the greatest burden of OSA symptoms with the highest mean Epworth Sleepiness Scale score (12.2 ± 5.9 versus 9.4 ± 5.2 in White men, 11.2 ± 5.9, in Black women, and 9.8 ± 5.6 in White women; P < 0.001). Compared with White men, Black men were 1.61 (95% CI [1.04-2.51]) times more likely to have witnessed apneas and 1.56 (95% CI [1.00-2.46]) times more likely to have drowsy driving at the time of OSA diagnosis. Conclusions: At the time of clinical diagnosis, Black men have greater disease severity, suggesting delay in diagnosis. Further, the greater burden of classic OSA symptoms suggests the delayed diagnosis of OSA in Black men is not due to atypical presentation. Further research is needed to identify why screening methods for OSA are not equitably implemented in the care of Black men.

Barriers and Facilitators to Resuming In-Person Psychotherapy with Perinatal Patients amid the COVID-19 Pandemic: A Multistakeholder Perspective.

During the COVID-19 pandemic, outpatient psychotherapy transitioned to telemedicine. This study aimed to examine barriers and facilitators to resuming in-person psychotherapy with perinatal patients as the pandemic abates. We conducted focus group and individual interviews with a sample of perinatal participants (n = 23), psychotherapy providers (n = 28), and stakeholders (n = 18) from Canada and the U.S. involved in the SUMMIT trial, which is aimed at improving access to mental healthcare for perinatal patients with depression and anxiety. Content analysis was used to examine perceived barriers and facilitators. Reported barriers included concerns about virus exposure in a hospital setting (77.8% stakeholders, 73.9% perinatal participants, 71.4% providers) or on public transportation (50.0% stakeholders, 26.1% perinatal participants, 25.0% providers), wearing a mask during sessions (50.0% stakeholders, 25.0% providers, 13.0% participants), lack of childcare (66.7% stakeholders, 46.4% providers, 43.5% perinatal participants), general transportation barriers (50.0% stakeholders, 47.8% perinatal participants, 25.0% providers), and the burden of planning and making time for in-person sessions (35.7% providers, 34.8% perinatal participants, 27.8% stakeholders). Reported facilitators included implementing and communicating safety protocols (72.2% stakeholders, 47.8% perinatal participants, 39.3% providers), conducting sessions at alternative or larger locations (44.4% stakeholders, 32.1% providers, 17.4% perinatal participants), providing incentives (34.8% perinatal participants, 21.4% providers, 11.1% stakeholders), and childcare and flexible scheduling options (31.1% perinatal participants, 16.7% stakeholders). This study identified a number of potential barriers and illustrated that COVID-19 has fostered and amplified barriers. Future interventions to facilitate resuming in-person sessions should focus on patient-centered strategies based on empathy regarding ongoing risk-aversion among perinatal patients despite existing safety protocols, and holistic thinking to make access to in-person psychotherapy easier and more accessible for perinatal patients.

Neighborhoods with Greater Prevalence of Minority Residents Have Lower Continuous Positive Airway Pressure Adherence.

Rationale: Limited data suggest racial disparities in continuous positive airway pressure (CPAP) adherence exist.Objectives: To assess whether CPAP adherence varies by neighborhood racial composition at a national scale.Methods: Telemonitoring data from a CPAP manufacturer database were used to assess adherence in adult patients initiating CPAP therapy between November 2015 and October 2018. Mapping ZIP code to ZIP code tabulation areas, age- and sex-adjusted CPAP adherence data at a neighborhood level was computed as a function of neighborhood racial composition. Secondary analyses adjusted for neighborhood education and poverty.Measurements and Main Results: Among 787,236 patients living in 26,180 ZIP code tabulation areas, the prevalence of CPAP adherence was 1.3% (95% confidence interval [CI], 1.0-1.6%) lower in neighborhoods with high (⩾25%) versus low (<1%) percentages of Black residents and 1.2% (95% CI, 0.9-1.5%) lower in neighborhoods with high versus low percentages of Hispanic residents (P < 0.001 for both), even after adjusting for neighborhood differences in poverty and education. Mean CPAP usage was similar across neighborhoods for the first 2 days, but by 90 days, differences in CPAP usage increased to 22 minutes (95% CI, 18-27 min) between neighborhoods with high versus low percentages of Black residents and 22 minutes (95% CI 17-27 min) between neighborhoods with high versus low percentages of Hispanic residents (P < 0.001 for both).Conclusions: CPAP adherence is lower in neighborhoods with greater proportions of Black and Hispanic residents, independent of education or poverty. These differences lead to a lower likelihood of meeting insurance coverage requirements for CPAP therapy, potentially exacerbating sleep health disparities.

Association of cardiovascular risk profile with healthcare expenditure and resource utilization in chronic obstructive pulmonary disease, with and without atherosclerotic cardiovascular disease.

OBJECTIVE: Atherosclerotic cardiovascular disease (ASCVD) and chronic obstructive pulmonary disease (COPD) are among the leading causes of morbidity, mortality, and economic burden in the United States (US). While previous reports have shown that an optimal cardiovascular risk factor (CRF) profile is associated with improved outcomes among COPD patients, the impact of ASCVD and CRF on healthcare costs and resource utilization is not well described. METHODS: The Medical Expenditure Panel Survey (MEPS) database was used from 2011 to 2016 to study healthcare expenditure for COPD patients with and without ASCVD and across CRF profiles in a nationally representative population of adults in the United States. RESULTS: The study population consisted of 14,807 adults with COPD, representing 28 million cases annually. Presence of ASCVD was associated with higher reported expenditure across the spectrum of CRF profiles among those with COPD. On average, after adjusting for confounders, presence of ASCVD represented a mean difference per capita of $5438 (95% CI $4121 - $6754; p â€‹< â€‹0.001). Mean per capita expenditures were significantly higher comparing poor vs optimal CRF profiles, with marginal expenditures of $8552 and $6531 among those with and without ASCVD, respectively. When comparing individuals with ASCVD and poor CRF profile versus individuals without ASCVD and optimal CRF profile, those in the latter group used 13% fewer prescription medications and required 24% fewer hospitalizations. Furthermore, an optimal CRF profile was associated with lower odds of most sources of healthcare utilization regardless of ASCVD status. CONCLUSION: An absence of ASCVD and a favorable CRF profile was associated with lower healthcare expenditure and resource utilization among patients with COPD. These results provide robust estimates for potential healthcare savings as preemptive strategies continue to become integrated into new healthcare delivery models, for increased awareness and the need for improvement of CRF profiles among high-risk patients.

Self-evaluation of ethical review committees functioning at Foundation University Medical College (FUMC) through structured constitution-practice-outcome (CPO) assessment model.

OBJECTIVE: To assess the operational efficiency of the ethical review committee of a medical college. METHODS: This study was conducted at the Foundation University Medical College, Islamabad, Pakistan, from 2012 to 2014. On the basis of literature review, methods for assessment of various features of ethical review committee were studied. A constitution-practice-outcome measurement model for evaluation of ethical review committee assessment process was developed. Data submitted to ethical review committee since its constitution was extracted and quantitatively analysed. RESULTS: The ethical review committee comprised 14 members, including 4(28.6%) permanent and 10(71.4%) rotating clinical, basic sciences and non-medical members. As many as 45 research protocols were submitted, with submission frequency of 8(17.8%), 12(26.7%) and 25(55.5%) per year respectively, and issued ethical approval certificates within a mean duration of 7.2±3.2 days from the time of first submission to final notification. Issues looked into were according to World Health Organisation guidelines. Standard review was done on 29(64.4%) studies and expedited on 16(35.5%). In addition, 24(53.3%) protocols needed resubmission. Only 2(4.4%) protocols were not approved. The number of issues raised for resubmission was 71. Main reasons for resubmission were found to be incomplete documents 26(36.6%), invalid informed consent forms 12(16.9%) and negligence in maintaining confidentiality of study participants 9(12.7%). CONCLUSIONS: Ethical review committee with its limited resources was fulfilling its founding objectives as depicted by constitution-practice-outcome model.
