RESUMO

OBJECTIVES: 'Healthier Wealthier Families' (HWF) seeks to reduce financial hardship in the early years by embedding a referral pathway between Australia's universal child and family health (CFH) services and financial counselling. This pilot study investigated the feasibility and short-term impacts of HWF, adapted from a successful Scottish initiative. METHODS: Setting: CFH services in five sites across two states, coinciding with the COVID-19 pandemic. PARTICIPANTS: Caregivers of children aged 0-5 years experiencing financial hardship (study-designed screen). DESIGN: Mixed methods. With limited progress using a randomised trial (RCT) design in sites 1-3 (March 2020-November 2021), qualitative interviews with service providers identified implementation barriers including stigma, lack of knowledge of financial counselling, low financial literacy, research burden and pandemic disruption. This informed a simplified RCT protocol (site 4) and direct referral model (no randomisation, pre-post evaluation, site 5) (June 2021-May 2022). INTERVENTION: financial counselling; comparator: usual care (sites 1-4). Feasibility measures: proportions of caregivers screened, enrolled, followed up and who accessed financial counselling. Impact measures: finances (quantitative) and other (qualitative) to 6 months post-enrolment. RESULTS: 355/434 caregivers completed the screen (60%-100% across sites). In RCT sites (1-4), 79/365 (19%-41%) reported hardship but less than one-quarter enrolled. In site 5, n=66/69 (96%) caregivers reported hardship and 44/66 (67%) engaged with financial counselling; common issues were utility debts (73%), and obtaining entitlements (43%) or material aid/emergency relief (27%). Per family, financial counselling increased income from government entitlements by an average $A6504 annually plus $A784 from concessions, grants, brokerage and debt waivers. Caregivers described benefits (qualitative) including reduced stress, practical help, increased knowledge and empowerment. CONCLUSIONS: Financial hardship screening via CFH was acceptable to caregivers, direct referral was feasible, but individual randomisation was infeasible. Larger-scale implementation will require careful, staged adaptations where CFH populations and the intervention are well matched and low burden evaluation. TRIAL REGISTRATION NUMBER: ACTRN12620000154909.

RESUMO

Treatment of tuberculosis continues to be challenging due to the widespread latent form of the disease and the emergence of antibiotic-resistant strains of the pathogen, Mycobacterium tuberculosis. Bacterial ribosomes are a common and effective target for antibiotics. Several second line anti-tuberculosis drugs, e.g. kanamycin, amikacin, and capreomycin, target ribosomal RNA to inhibit protein synthesis. However, M. tuberculosis can acquire resistance to these drugs, emphasizing the need to identify new drug targets. Previous cryo-EM structures of the M. tuberculosis and M. smegmatis ribosomes identified two novel ribosomal proteins, bS22 and bL37, in the vicinity of two crucial drug-binding sites: the mRNA-decoding center on the small (30S), and the peptidyl-transferase center on the large (50S) ribosomal subunits, respectively. The functional significance of these two small proteins is unknown. In this study, we observe that an M. smegmatis strain lacking the bs22 gene shows enhanced susceptibility to kanamycin compared to the wild-type strain. Cryo-EM structures of the ribosomes lacking bS22 in the presence and absence of kanamycin suggest a direct role of bS22 in modulating the 16S rRNA kanamycin-binding site. Our structures suggest that amino-acid residue Lys-16 of bS22 interacts directly with the phosphate backbone of helix 44 of 16S rRNA to influence the micro-configuration of the kanamycin-binding pocket. Our analysis shows that similar interactions occur between eukaryotic homologues of bS22, and their corresponding rRNAs, pointing to a common mechanism of aminoglycoside resistance in higher organisms.

RESUMO

Cognitive inflexibility and attention to detail bias represent a promising target in eating disorder (ED) treatment. While prior research has found that adults with eating disorders exhibit significant cognitive inflexibility and heightened attention to detail, less is known about these cognitive impairments among adolescents, and across EDs transdiagnostically. To address this gap, adolescent females (N = 143) from a residential ED program with anorexia nervosa, bulimia nervosa, or other specified feeding or eating disorder completed the Detail and Flexibility Questionnaire (DFlex) and measures of ED and general psychopathology. Transdiagnostically, adolescents with EDs scored higher than an archival sample of healthy control adolescents on both cognitive rigidity (p < .001; Cohen's d = 1.92) and attention to detail (p < .001; Cohen's d = 1.16). These cognitive impairments were significantly associated with severity of eating pathology, and these relationships existed independent of age, duration of illness, or body mass index (BMI). Our findings suggest cognitive inflexibility and heightened attention to detail occur transdiagnostically in adolescents with eating disorders and are unlikely to be a scar of the disorder. Future prospective research is needed to determine whether these cognitive styles represent an endophenotype of eating disorders.

RESUMO

OBJECTIVE: To determine the relationship between opioid dose change, pain severity, and function in patients with chronic pain. DESIGN: Retrospective cohort study. SETTING: Community interdisciplinary pain management practice. SUBJECTS: A total of 778 patients with chronic pain prescribed opioids for three or more consecutive months between April 1, 2013, and March 1, 2015. METHODS: Changes in opioid dose, pain severity rating, modified Roland Morris Disability Questionnaire score, and opioid risk data were extracted from medical records and analyzed for associations. RESULTS: Two hundred forty-three subjects (31.2%) had an overall dose decrease, 223 (28.7%) had a dose increase, and 312 (40.1%) had no significant change in dose (<20% change). There was a weak negative correlation between change in opioid dose and change in pain severity (r = -0.08, P = 0.04) but no association between change in disability scores and dose change (N = 526, P = 0.13). There was a weak positive correlation between change in pain severity rating and change in disability scores (r = 0.16, P < 0.001). CONCLUSIONS: The results suggest that escalating opioid doses may not necessarily result in clinically significant improvement of pain or disability. Similarly, significant opioid dose reductions may not necessarily result in worsened pain or disability. This exploratory investigation raised questions of possible subgroups of patients who might demonstrate improvement of pain and disability with opioid dose adjustments, and further research should prospectively explore this potential, given the limitations inherent in retrospective analyses. Prescribers should still consider reduction of opioid doses as recommended by current guidelines, in an effort to mitigate the potential risks associated with high-dose treatment.

RESUMO

Migraine can impact every aspect of a person's functioning. Psychological comorbidities, cognitive constructs, and behavioral responses to pain greatly impact the perception of migraine pain, treatment efficacy and outcome, and overall quality of life and functioning. Current considerations for migraine treatment emphasize the utility of the biopsychosocial model in understanding and treating migraine, noting both the importance of addressing psychological factors such as cognitive beliefs as well as psychiatric comorbidities. The guidelines for migraine treatment implicate opioid therapy as a second or third tier treatment. Guidelines and recommendations for the safe use of opioid medications among patients with chronic pain emphasize the importance of screening prior to prescribing opioid medications. Chronic opioid therapy has been shown to further levels of disability, decrease quality of life, and correlate to psychiatric comorbidities, concerns that are already present in migraine patients. While opioid treatment provides an alternative for persons with contraindications for alternative migraine treatments, it is critical that opioids be used sparingly and exclusively in conjunction with comprehensive assessment and integration of psychological treatment.

RESUMO

Migration is a primary force of biological evolution that alters allele frequencies and introduces novel genetic variants into populations. Recent migration has been proposed as the cause of the emergence of many infectious diseases, including those carried by blacklegged ticks in North America. Populations of blacklegged ticks have established and flourished in areas of North America previously thought to be devoid of this species. The recent discovery of these populations of blacklegged ticks may have resulted from either in situ growth of long-established populations that were maintained at very low densities or by migration and colonization from established populations. These alternative evolutionary hypotheses were investigated using Bayesian phylogeographic approaches to infer the origin and migratory history of recently detected blacklegged tick populations in the Northeastern United States. The data and results indicate that newly detected tick populations are not the product of in situ population growth from a previously established population but from recent colonization resulting in a geographic range expansion. This expansion in the geographic range proceeded primarily through progressive and local migration events from southern populations to proximate northern locations although long-distance migration events were also detected.

RESUMO

This study evaluated the relative distribution and inter-rater reliability of revised DSM-5 criteria for eating disorders in a residential treatment program. Consecutive adolescent and young adult females (N=150) admitted to a residential eating disorder treatment facility were assigned both DSM-IV and DSM-5 diagnoses by a clinician (n=14) via routine clinical interview and a research assessor (n=4) via structured interview. We compared the frequency of diagnostic assignments under each taxonomy and by type of assessor. We evaluated concordance between clinician and researcher assignment through inter-rater reliability kappa and percent agreement. Significantly fewer patients received either clinician or researcher diagnoses of a residual eating disorder under DSM-5 (clinician-12.0%; researcher-31.3%) versus DSM-IV (clinician-28.7%; researcher-59.3%), with the majority of reassigned DSM-IV residual cases reclassified as DSM-5 anorexia nervosa. Researcher and clinician diagnoses showed moderate inter-rater reliability under DSM-IV (κ=.48) and DSM-5 (κ=.57), though agreement for specific DSM-5 other specified feeding or eating disorder (OSFED) presentations was poor (κ=.05). DSM-5 revisions were associated with significantly less frequent residual eating disorder diagnoses, but not with reduced inter-rater reliability. Findings support specific dimensions of clinical utility for revised DSM-5 criteria for eating disorders.

RESUMO

The use of chronic opioid therapy for persistent headache remains controversial because of limited supporting data and potential risks. In addition to possible individual risks for the patient, society risks associated with diversion and substance abuse are well documented. Few studies directly address risk stratification for opioid therapy where a diagnosis of headache is present, making it necessary to extrapolate from other pain research when developing recommendations for screening and patient management. Considering the historical framework of opioid prescribing, relevant studies assessing risk stratification of chronic opioid therapy are reviewed. Specific risk factors that may lead to a problematic course with chronic opioid therapy are outlined. Both clinical experience and the limited empirical research underscore the need for multiple assessment tools and ongoing patient monitoring in the evaluation of these risk factors.

RESUMO

The population densities of many organisms have changed dramatically in recent history. Increases in the population density of medically relevant organisms are of particular importance to public health as they are often correlated with the emergence of infectious diseases in human populations. Our aim is to delineate increases in density of a common disease vector in North America, the blacklegged tick, and to identify the environmental factors correlated with these population dynamics. Empirical data that capture the growth of a population are often necessary to identify environmental factors associated with these dynamics. We analyzed temporally- and spatially-structured field collected data in a geographical information systems framework to describe the population growth of blacklegged ticks (Ixodes scapularis) and to identify environmental and climatic factors correlated with these dynamics. The density of the ticks increased throughout the study's temporal and spatial ranges. Tick density increases were positively correlated with mild temperatures, low precipitation, low forest cover, and high urbanization. Importantly, models that accounted for these environmental factors accurately forecast future tick densities across the region. Tick density increased annually along the south-to-north gradient. These trends parallel the increases in human incidences of diseases commonly vectored by I. scapularis. For example, I. scapularis densities are correlated with human Lyme disease incidence, albeit in a non-linear manner that disappears at low tick densities, potentially indicating that a threshold tick density is needed to support epidemiologically-relevant levels of the Lyme disease bacterium. Our results demonstrate a connection between the biogeography of this species and public health.
