RESUMO

A key open issue in condensed-matter physics is how quantum and classical correlations emerge in an unconventional superconductor from the underlying normal state. We study this problem in a doped Mott insulator with information-theory tools on the two-dimensional (2D) Hubbard model at finite temperature with cluster dynamical mean-field theory. We find that the local entropy detects the superconducting state and that the difference in the local entropy between the superconducting and normal states follows the same difference in the potential energy. We find that the thermodynamic entropy is suppressed in the superconducting state and monotonically decreases with decreasing doping. The maximum in entropy found in the normal state above the overdoped region of the superconducting dome is obliterated by superconductivity. The total mutual information, which quantifies quantum and classical correlations, is amplified in the superconducting state of the doped Mott insulator for all doping levels and shows a broad peak versus doping, as a result of competing quantum and classical effects.

RESUMO

The cytogenetic alterations in renal oncocytoma (RO) are poorly understood. We analyzed 130 consecutive RO for karyotypic alterations. Clonal chromosome abnormalities were identified in 63 (49%) cases, which could be categorized into three classes of mutually exclusive cytogenetic categories. Class 1 (N = 20) RO had diploid karyotypes with characteristic 11q13 rearrangement in balanced translocations with 10 or more different chromosome partners in all cases. We identified recurrent translocation partners at 5q35, 6p21, 9p24, 11p13-14, and 11q23, and confirmed that CCND1 gene rearrangement at 11q13 utilizing fluorescence in situ hybridization (FISH). Class 2 RO (N = 25) exhibited hypodiploid karyotypes with loss of chromosome 1 and/or losses of Y in males and X in females in all cases. The class 3 tumors comprising of 18 cases showed diverse types of abnormalities with the involvement of two or more chromosomes exclusive of abnormalities seen in classes 1 and 2 tumors. Furthermore, karyotypically uninformative cases were subjected to FISH analysis to identify classes 1 and 2 abnormalities. In this group, we found similar frequencies of CCND1 rearrangement, loss of chromosome 1 or Y as with karyotypically abnormal cases. We validated our results against 91 tumors from the Mitelman database. Correlation of clinical data with all the three classes of ROs showed no clear evidence of overall patient survival. Our findings support the hypothesis that RO exhibit three principal cytogenetic categories, which may have different roles in initiation and/or progression. These cytogenetic markers provide a key tool in the diagnostic evaluation of RO.

RESUMO

Health sector strategic plans are health policies outlining health service delivery in low- and middle- income countries, guiding health sectors to meet health needs while maximizing resources. However, little research has explored the formulation of these plans. This study utilized qualitative methods to explore the formulation of Malawi's Health Sector Strategic Plan II, including processes utilized, actors involved, important contextual factors and the use of evidence-based decision-making. Thirteen semi-structured key informant interviews with health policy actors were conducted to explore perceptions and experiences of formulating the policy. Data analysis used an inductive-deductive approach and interpretation of the data was guided by an adapted version of the Walt and Gilson Health Policy Triangle. Our results indicate that HSSP II formulation was complex and inclusive but that the Ministry of Health may have given up ownership of the formulation process to development partners to ensure their continued involvement. Disagreements between actors centered around inclusion of critical services in the Essential Health Package and selection of performance-based financing as purchasing strategy. Resource constraints and the Cashgate Scandal are critical contextual elements influencing the formulation and content of the policy. Evidence-based decision-making contributed to the plan's development despite respondents' divergent opinions regarding evidence availability, quality and the weight that evidence carried. The study raises questions regarding the roles of policy actors during health policy formulation, the inclusivity of health policy processes and their potential influence on government ownership of health policy, as well as the use of evidence in developing health sector strategic plans.

RESUMO

OBJECTIVES: US community pharmacies are a unique and underused health service setting for identifying and potentially intervening with patients at risk of opioid overdose or opioid use disorder with evidence-based practices such as screening, brief intervention, and referral to treatment (SBIRT). The aim of our study was to assess the feasibility of implementing SBIRT in community pharmacies in an urban county in terms of engagement, reach, and equity across the cascade of pharmacy screening and care. METHODS: Patients aged 18 years or older receiving a schedule II or III opioid prescription at 1 of 17 participating community pharmacies in Allegheny County, Pennsylvania, were invited to engage in SBIRT as part of Project Lifeline-II from June 2020 through January 2023. Participants completed a prescreen and/or a full screen. We calculated the percentage of patients who participated across the cascade of pharmacy screening and care, overall and by sex (male and female) and race (Black and White). RESULTS: During the study period, 1952 unique adults (79.6%) were screened at least once (52.1% female; 58.0% White, 30.7% Black). Patients who identified as male (vs female) and Black (vs White) were more likely to have a positive prescreen (14.7% male vs 9.8% female; 16.4% Black vs 9.5% White), receive and complete a full screen (82.7% male vs 80.0% female; 83.6% Black vs 78.4% White), and score positively on the full screen (26.6% male vs 20.4% female; 26.8% Black vs 21.9% White). CONCLUSION: Although additional research is needed to characterize the full effect of Project Lifeline-II on patient outcomes, our findings help reinforce the benefits of multipronged public health initiatives that include community pharmacists to address the substance use disorder crisis in the United States.

RESUMO

India launched one of the world's largest health insurance programs, the Pradhan Mantri Jan Arogya Yojana (PM-JAY), targeting more than 500 million economically and socially disadvantaged Indians. PM-JAY is publicly funded and covers hospitalization costs in public and private facilities. We examine how PM-JAY has affected hospitalizations and out-of-pocket expenditures (OOPE), and given the high use of private health care in India, we compare these outcomes across public and private facilities. We conducted a household survey to collect data on socioeconomic and demographic information, health status and hospitalizations for more than 57,000 PM-JAY eligible individuals in six Indian states. Using multivariate regression models, we estimated whether PM-JAY was associated with any changes in hospitalizations, OOPE and catastrophic health expenditures (CHE) and whether these differed across public and private facilities. We found that PM-JAY was not associated with an increase in hospitalizations, but it increased the probability of visiting a private facility by 4.6% points (p < .05). PM-JAY was associated with a relative reduction of 13% in OOPE (p < .1) and 21% in CHE (p < .01). This was entirely driven by private facilities, where relative OOPE was reduced by 17% (p < .01) and CHE by 19% (p < .01). This implied that PM-JAY has shifted use from public to private hospitalizations. Given the complex healthcare system with the presence of parallel public and private systems in India, our study concludes that for economically and socially disadvantaged groups, PM-JAY contributes to improved access to secondary and tertiary care services from private providers.

RESUMO

The literature suggests that a first barrier towards accessing benefits of health insurance in low- and middle-income countries is lack of awareness of one's benefits. Yet, across settings and emerging schemes, limited scientific evidence is available on levels of awareness and their determinants. To fill this gap, we assessed socio-demographic and economic determinants of beneficiaries' awareness of the Pradhan Mantri Jan Arogya Yojana (PM-JAY), the national health insurance scheme launched in India in 2018, and their awareness of own eligibility. We relied on cross-sectional household (HH) survey data collected in six Indian states between 2019 and 2020. Representative data of HHs eligible for PM-JAY from 11 618 respondents (an adult representative from each surveyed HH) were used. We used descriptive statistics and multivariable logistic regression models to explore the association between awareness of PM-JAY and of one's own eligibility and socio-economic and demographic characteristics. About 62% of respondents were aware of PM-JAY, and among the aware, 78% knew that they were eligible for the scheme. Regression analysis confirmed that older respondents with a higher educational level and salaried jobs were more likely to know about PM-JAY. Awareness was lower among respondents from Meghalaya and Tamil Nadu. Respondents from Other Backward Classes, of wealthier socio-economic status or from Meghalaya or Gujarat were more likely to be aware of their eligibility status. Respondents from Chhattisgarh were less likely to know about their eligibility. Our study confirms that while more than half of the eligible population was aware of PM-JAY, considerable efforts are needed to achieve universal awareness. Socio-economic gradients confirm that the more marginalized are still less aware. We recommend implementing tailored, state-specific information dissemination approaches focusing on knowledge of specific scheme features to empower beneficiaries to demand their entitled services.

RESUMO

CONTEXT: The detection of low-level persistent or relapsed B-cell neoplasms, particularly post-therapy, can be challenging, often requiring multiple testing modalities. OBJECTIVE: Here we investigate the utility of CD19-based selection of neoplastic B-cells (CD19S) as an enrichment strategy to improve the detection rate of cytogenetic abnormalities in post-therapy samples of B-cell neoplasms, especially those with low-level disease. DESIGN: In a cohort largely comprised of post-therapy B-ALL and CLL samples, we performed fluorescence in situ hybridization (FISH) analysis on CD19-selected cells (CD19S FISH) in 128 specimens from 88 patients, and on non-selected cells (NS FISH) in a subset of cases. The FISH findings were compared with the concurrent flow cytometry (FC) results in all samples and molecular analysis in a subset. RESULTS: CD19S FISH was able to detect cytogenetic aberrations in 86.0% of post-therapy samples with evidence of disease as determined by routine or MRD FC, compared to 59.1% of samples by NS FISH. CD19S FISH detected significantly higher percentages of positive cells compared to NS FISH (p < 0.001). Importantly, CD19S FISH enabled the detection of emergent subclones (clonal evolution) associated with poor prognosis. CONCLUSIONS: CD19S FISH can be useful in daily diagnostic practice. Compared to NS FISH, CD19S FISH is quantitatively and qualitatively superior for the detection of cytogenetic aberrations in B-cell neoplasms, which are important for risk stratification and optimal management of patients with B-cell neoplasms, especially in the relapsed setting. Although CD19S FISH has a diagnostic sensitivity inferior to that of MRD FC, the sensitivity of this modality is comparable to routine FC for the evaluation of low-level disease in the post-therapy setting. Moreover, CD19S samples are invaluable for additional molecular and genetic analyses.

RESUMO

In September 2018, India launched Pradhan Mantri Jan Arogya Yojana (PM-JAY), a nationally implemented government-funded health insurance scheme to improve access to quality inpatient care, increase financial protection, and reduce unmet need for the most vulnerable population groups. This protocol describes the methodology adopted to evaluate implementation processes and early effects of PM-JAY in seven Indian states. The study adopts a mixed and multi-methods concurrent triangulation design including three components: 1. demand-side household study, including a structured survey and qualitative elements, to quantify and understand PM-JAY reach and its effect on insurance awareness, health service utilization, and financial protection; 2. supply-side hospital-based survey encompassing both quantitative and qualitative elements to assess the effect of PM-JAY on quality of service delivery and to explore healthcare providers' experiences with scheme implementation; and 3. process documentation to examine implementation processes in selected states transitioning from either no or prior health insurance to PM-JAY. Descriptive statistics and quasi-experimental methods will be used to analyze quantitative data, while thematic analysis will be used to analyze qualitative data. The study design presented represents the first effort to jointly evaluate implementation processes and early effects of the largest government-funded health insurance scheme ever launched in India.

RESUMO

Goniodysgenesis is a developmental abnormality of the anterior chamber of the eye. It is generally considered to be congenital in dogs (Canis lupus familiaris), and has been associated with glaucoma and blindness. Goniodysgenesis and early-onset glaucoma initially emerged in Border Collies in Australia in the late 1990s and have subsequently been found in this breed in Europe and the USA. The objective of the present study was to determine the genetic basis of goniodysgenesis in Border Collies. Clinical diagnosis was based on results of examinations by veterinary ophthalmologists of affected and unaffected dogs from eleven different countries. Genotyping using the Illumina high density canine single nucleotide variant genotyping chip was used to identify a candidate genetic region. There was a highly significant peak of association over chromosome 17, with a p-value of 2 × 10-13 Expression profiles and evolutionary conservation of candidate genes were assessed using public databases. Whole genome sequences of three dogs with glaucoma, three severely affected by goniodysgenesis and three unaffected dogs identified a missense variant in the olfactomedin like 3 (OLFML3) gene in all six affected animals. This was homozygous for the risk allele in all nine cases with glaucoma and 12 of 14 other severely affected animals. Of 67 reportedly unaffected animals, only one was homozygous for this variant (offspring of parents both with goniodysgenesis who were also homozygous for the variant). Analysis of pedigree information was consistent with an autosomal recessive mode of inheritance for severe goniodysgenesis (potentially leading to glaucoma) in this breed. The identification of a candidate genetic region and putative causative variant will aid breeders to reduce the frequency of goniodysgenesis and the risk of glaucoma in the Border Collie population.

RESUMO

There is little research on the functional assessment and treatment of anxiety and related problem behavior in children with autism spectrum disorder (ASD), particularly those with intellectual and developmental disability (IDD). In a recent study, we evaluated a multimethod strategy for assessing anxiety in children with ASD and IDD (Am J Intellect Dev Disabil 118:419-434, 2013). In the present study, we developed treatments for the anxiety and associated problem behavior in these same children. A multiple baseline design was used to evaluate the effectiveness of a multicomponent intervention package, incorporating individualized strategies from Positive Behavior Support and Cognitive Behavioral Therapy. During intervention, all three participants showed substantial decreases in anxiety and problem behavior and significant increases in respiratory sinus arrhythmia in the situations that had previously been identified as anxiety-provoking.

RESUMO

Evidence suggests that pain interferes with sleep in youth with developmental disabilities. This study examined the relationship between pain and sleep problems in a sample of youth with parent-reported autism spectrum disorder (N = 62). Mothers reported on standardized measures of pain and sleep problems. Youth demonstrated atypically high levels of both observed pain and sleep problems. Pain predicted overall sleep disturbance and three specific sleep problems: sleep duration, parasomnias, and sleep-disordered breathing. These specific sleep problems were predicted by specific modalities of nonverbal pain communication (e.g. sleep duration problems were predicted by social communication of pain). Effects were consistent across probing of relevant moderators. These findings suggest that comprehensive assessment of both pain and sleep problems may provide important information for medical and behavioral treatment planning for youth with autism spectrum disorder.

RESUMO

Despite the increased risk for anxiety disorders in children with autism spectrum disorders (ASD), there is a lack of research on the assessment and treatment of anxiety in this population, particularly for those with an intellectual disability (ID). The present study evaluated a multimethod strategy for the assessment of anxiety and problem behavior in three children with ASD and ID. Anxiety was operationally defined using: (1) behavioral data from anxious behaviors, (2) affective/contextual data from parent-report and observer ratings of overall anxiety, and (3) physiological data (heart rate [HR] and respiratory sinus arrhythmia [RSA]). A functional assessment of problem behavior during high- and low-anxiety conditions was conducted. Higher levels of problem behavior and HR and lower RSA were found in the high-anxiety than in the low-anxiety conditions.
