RESUMO

Purpose: Traditional value assessment frameworks are challenged in comprehensively assessing the societal value new therapies bring to individuals with rare, progressive, genetic, fatal, neuromuscular diseases such as Duchenne muscular dystrophy (DMD). The objective of this study was to identify how value assessment frameworks may need to be adapted to measure the value to society of DMD therapies. Patients and Methods: Three stakeholder groups (6 patient advocates, 4 clinicians, 3 health economists; N = 13) participated in semi-structured interviews around the International Society for Pharmacoeconomics and Outcomes Research's Value Flower, which includes elements to consider within value assessments of healthcare technologies. Results: All stakeholders agreed that traditional value assessment frameworks based on the quality-adjusted life year (QALY) are narrow and will undervalue new DMD therapies. All stakeholders expressed some level of concern that using the QALY as a key metric of value discriminates against patients with severe progressive diseases and disabilities. Some stakeholders saw value in using the QALY for cross-disease comparisons in resource-constrained environments if the methodology was appropriate. All stakeholders recommended considering additional elements of value in decision-making around new DMD therapies. These elements reflect: economic and humanistic costs incurred by patients, caregivers, and families with Duchenne, such as indirect out-of-pocket costs, lost productivity, and family spillovers; meaningful attributes for individuals with disabilities and high unmet need, such as severity of disease, value of hope, and real option value; and factors that contribute to improvements in population health, such as insurance value, equity, and scientific spillovers. Conclusion: These findings highlight the need to expand traditional value assessment frameworks and take a holistic approach that incorporates the perspectives of individuals with Duchenne, caregivers, clinicians, and health economists when assessing the societal value of new DMD therapies. Broadening value assessment will prevent restricted or delayed access to therapies for individuals with Duchenne.

RESUMO

Natural pigments extracted from plant species are used in foods, cosmetics, and pharmaceuticals. This study evaluates the comprehensive biological activities of anthocyanins isolated from Andean blueberry (Vaccinium floribundum Kunth) and Andean blackberry (Rubus glaucus Benth), focusing on their antimicrobial, antioxidant, antitumoral, anti-inflammatory, and hemolytic properties. Chemical characterization revealed significant anthocyanin content with complex mass spectrometric profiles indicating diverse glycosylation patterns that may influence their bioactivity. The antimicrobial assays showed that the extracts were particularly effective against Gram-positive bacteria, with minimal inhibitory concentrations (MICs) as low as 1 mg/mL for Rubus glaucus, indicating strong potential for therapeutic use. The antioxidant capacity of the berries was substantial, albeit slightly lower than that of ascorbic acid. The extracts also exhibited notable antitumoral activity in various cancer cell lines, showing promise as adjunctive or preventive treatments. The anti-inflammatory effects were confirmed by inhibiting nitric oxide production in macrophage cells, highlighting their potential in managing inflammatory diseases. In terms of hemolytic activity, Rubus glaucus exhibited dose-dependent effects, potentially attributable to anthocyanins and phenolics, while Vaccinium floribundum demonstrated no significant hemolytic activity, underscoring its safety. These findings suggest that anthocyanins from Andean berries possess potent biological activities, which could be leveraged for health benefits in pharmaceutical and nutraceutical applications. Further studies are needed to isolate specific bioactive compounds and investigate their synergistic effects in clinical and real-world contexts.

RESUMO

Objective: To evaluate the association between different types of human milk feeds and bronchopulmonary dysplasia (BPD) in preterm infants. Methods: Data on dispensed mother's own milk (MOM) and donor human milk (DHM) from Leipzig Milk Bank for hospitalized infants with a gestational age (GA) ≤32 weeks observed from birth to 36 weeks' postmenstrual age or prior discharge were used. BPD was assessed based on documented International Statistical Classification of Diseases and Related Health Problems (ICD) diagnosis and on electronic hospital records (EHR) of data on ventilation and oxygen supplementation. Associations of dispensed milk feed variations with BPD were investigated using logistic regressions in crude and adjusted models. Results: 866 infants were included with a BPD prevalence of 15.4% (EHR) and 23.2% (ICD). The mean GA was 29.1 weeks. The majority (84.4%, n = 746) of infants were nurtured with a mix of MOM, DHM supplemented by formula or parenteral (other) nutrition during hospitalization. For which, MOM comprised the highest median [Q1-Q3] percentage proportion (53[31-81] %) of this mix. Exclusive fresh milk and exclusive MOM feeds were dispensed on a mean of 40 and 34% patient-days, respectively. Statistically significant associations with lower BPD incidence were only observed for 70-80% MOM vs. DHM, and 60% fresh vs. frozen milk, in crude and adjusted models. Conclusion: Our findings suggest a protective association of MOM and fresh milk with lower odds of BPD, which may be dependent on the proportion of MOM or fresh milk administered. These results highlight the importance of MOM as an ideal source of nutrition during early infancy.

RESUMO

Finding developmentally appropriate ways to support youth in understanding their own ethnic-racial identity is needed, particularly in contexts like Sweden where such support is not the norm. This preregistered longitudinal study examined whether an 8-week school-based intervention, the Identity Project, impacted youth ethnic-racial identity exploration (participation and search), resolution, private regard, and centrality. Participants were 509 adolescents in the 10th grade (Mage = 16.28, SD = 0.80; 65% self-identified girls; 52% minoritized ethnic background), who were randomized into an intervention or wait-list control group and assessed at baseline and three times post-intervention. The findings indicated an initial and simultaneous effect of the intervention only for exploration participation and resolution but did not show the expected chain of effects with earlier exploration predicting later resolution. Growth models indicated a greater increase in exploration participation over time for the intervention group than the control group. The findings indicate a mixed picture about the effectiveness of the intervention, with effects primarily narrowly targeted to exploration participation, but nevertheless highlight the potential for supporting Swedish youth in engaging with their ethnic-racial identities.

RESUMO

Cancer is a significant global socioeconomic burden, as millions of new cases and deaths occur annually. In 2020, almost 10 million cancer deaths were recorded worldwide. Advancements in cancer gene therapy have revolutionized the landscape of cancer treatment. An approach with promising potential for cancer gene therapy is introducing genes to cancer cells that encode for chemotherapy prodrug metabolizing enzymes, such as Cytochrome P450 (CYP) enzymes, which can contribute to the effective elimination of cancer cells. This can be achieved through gene-directed enzyme prodrug therapy (GDEPT). CYP enzymes can be genetically engineered to improve anticancer prodrug conversion to its active metabolites and to minimize chemotherapy side effects by reducing the prodrug dosage. Rational design, directed evolution, and phylogenetic methods are some approaches to developing tailored CYP enzymes for cancer therapy. Here, we provide a compilation of genetic modifications performed on CYP enzymes aiming to build highly efficient therapeutic genes capable of bio-activating different chemotherapeutic prodrugs. Additionally, this review summarizes promising preclinical and clinical trials highlighting engineered CYP enzymes' potential in GDEPT. Finally, the challenges, limitations, and future directions of using CYP enzymes for GDEPT in cancer gene therapy are discussed.

RESUMO

INTRODUCTION: Improving surgical access in low- and middle-income countries is vital for the 5 billion people who lack safe surgical care. Tailoring a culturally sensitive approach to consent is essential for patient comprehension and comfort, thereby alleviating the effects of resource constraints and advancing equitable care. This study examines the consenting process for endoscopy at Kyabirwa Surgical Center in Kyabirwa, Jinja, Uganda, to assess patients' knowledge and attitudes as a potential barrier to participating in endoscopic procedures. METHODS: All adult upper endoscopy (EGD) and colonoscopy patients were recruited to participate in a survey of their demographics, knowledge, and attitudes toward their procedure. All patients received a standard consultation explaining the procedure and its risks and benefits. RESULTS: 75 patients were included; median age was 54 years and 56% (n = 42) were women. 92% (n = 69) of patients had never had an endoscopy before and 73% (n = 55) of patients were scheduled for an EGD while the remaining 27% (n = 20) were scheduled for a colonoscopy. Most patients 80% (n = 60) had a basic understanding of what an endoscopy is and 87% (n = 65) its diagnostic purpose. Few patients 15% (n = 11) knew of the most common side effects or if they would have a surgical scar 27% (n = 20). Overall, 46.7% (n = 35) of patients were moderately or severely fearful of getting an endoscopy. Additionally, 45.3% (n = 34) of patients were moderately or severely fearful of receiving anesthesia during their endoscopic procedure. Despite this fear, most patients 85.3% (n = 64) stated that they understood the benefits of the procedure either very well or extremely well. CONCLUSIONS: Most patients understood the role that an endoscopic procedure plays in their care and its potential benefits. Despite this, many patients continued to have high levels of fear associated with both the endoscopic procedure and with receiving anesthesia during their procedure. Future patient education should focus on addressing patients' fears and the risks of undergoing an endoscopy, which may improve the utilization of surgical services.

RESUMO

Outgroup and diversity attitudes are important components of intercultural understanding and well-being. Despite the potential of ethnic-racial identity development as a means to foster positive outgroup and diversity attitudes, little is known about its effectiveness in rapidly diversifying contexts such as Sweden. This pre-registered study filled this gap by examining if adolescents taking part in an intervention focused on ethnic-racial identity exploration, the Identity Project, also reported change in outgroup and diversity attitudes, and whether migration background, education type, and ethnic-racial identity development predicted such change. Twenty-three tenth-grade classes in Sweden (N = 509; Mage = 16.28; SDage = 0.80; 66% female; 51% migration background) participated in the intervention and were assessed in four waves over a period of 26 weeks. Whereas ethnic-racial identity exploration and resolution increased for the intervention group, the adolescents reported no change in outgroup and diversity attitudes when compared to a control group. Increases in ethnic-racial identity exploration and resolution co-varied with increases in attitudes, but only at Time 3. The results do not provide support for the link between ethnic-racial identity development and positive outgroup and diversity attitudes, and challenge the notion of attitude change as a cascading effect of the Identity Project intervention in non-US sociocultural contexts. All aspects of the study were pre-registered on the Open Science Framework platform ( https://osf.io/f5896 ).

RESUMO

BACKGROUND: Access to minimally invasive surgery (MIS) is limited in Sub-Saharan African countries. In 2019, the Mount Sinai Department of Surgery in New York collaborated with local Ugandans to construct the Kyabirwa Surgical Center (KSC), an independent, replicable, self-sustaining ambulatory surgical center in Uganda. We developed a focused MIS training program using a combination of in-person training and supervised telementoring. We present the results of our initial MIS telementoring experience. METHODS: We worked jointly with Ugandan staff to construct the KSC in the rural province of Jinja. A solar-powered backup battery system ensured continuous power availability. Underground fiber optic cables were installed to provide stable high-speed Internet. The local Ugandan general surgeon (JOD) underwent a mini-fellowship in MIS and then trained extensively using the Fundamentals of Laparoscopic Surgery program. After a weeklong in-person session to train the Ugandan OR team, JOD performed laparoscopic cases with telementoring, which was conducted remotely by surgeons in New York via audiovisual feeds from the KSC OR. RESULTS: From October 2021 to February 2024, JOD performed 61 telementored laparoscopic operations at KSC including 37 appendectomies and 24 cholecystectomies. Feedback was provided regarding patient positioning, port placement, surgical technique, instrument use, and critical steps of the operation. There were no intra-operative complications. Postoperatively, field medical workers visited patients at home to collect follow-up information. Two superficial wound infections (3.3%) were reported in the short-term follow-up. CONCLUSION: Telementoring can be safely implemented to assist surgeons in previously underserved areas to provide advanced laparoscopic surgical care to the local patient population.

RESUMO

Given the significance of heritage cultural identity for optimal adolescent development, it is imperative to investigate factors influencing the efficacy of interventions aimed at promoting heritage cultural identity. Using latent profile cluster analysis and multinomial logistic regressions, this longitudinal study examined how autonomy and relatedness need satisfaction at school (1) related to heritage cultural identity development trajectories, and (2) moderated effects of a school-based intervention. The study included N = 198 adolescents (Mage = 12.86 years, SDage = 0.75, 52% female, 41% immigrant descent, 49% intervention group) in Germany. Teacher-student relationships played an important role in facilitating intervention effects on identity development trajectories, emphasizing the importance of the relational context when implementing school-based interventions to promote heritage cultural identity development.

RESUMO

Previous research has demonstrated therapeutic potential for VMAT2 inhibitors in rat models of methamphetamine use disorder. Here, we report on the neurochemical and behavioral effects of 1-(2-methoxyphenethyl)-4-phenethypiperazine (JPC-141), a novel analog of lobelane. JPC-141 potently inhibited (Ki = 52 nM) [3H]dopamine uptake by VMAT2 in striatal vesicles with 50 to 250-fold greater selectivity for VMAT2 over dopamine, norepinephrine and serotonin plasmalemma transporters. Also, JPC-141 was 57-fold more selective for inhibiting VMAT2 over [3H]dofetilide binding to hERG channels expressed by HEK293, suggesting relatively low potential for cardiotoxicity. When administered in vivo to rats, JPC-141 prevented the METH-induced reduction in striatal dopamine content when given either prior to or after a high dose of METH, suggesting a reduction in METH-induced dopaminergic neurotoxicity. In behavioral assays, JPC-141 decreased METH-stimulated locomotor activity in METH-sensitized rats at doses of JPC-141 which did not alter locomotor activity in the saline control group. Moreover, JPC-141 specifically decreased iv METH self-administration at doses that had no effect on food-maintained responding. These findings support the further development of VMAT2 inhibitors as pharmacotherapies for individuals with methamphetamine use disorder.

RESUMO

ABSTRACT: BACKGROUND: Nurses are key in identifying and treating in-hospital strokes (IHSs). Delayed treatment times and poor patient outcomes are associated with IHSs. Information is needed on nurses' stroke knowledge and the objective measurement of stroke knowledge using a validated tool. The Acute Stroke Management Questionnaire (ASMaQ) was recently developed to test stroke knowledge of healthcare professionals but has not been used on a nursing-specific population. METHODS: Through online surveying and use of ASMaQ, we will measure stroke knowledge of nurses caring for adult, hospitalized patients in an urban, southeast US health system. RESULTS: Total N is 196. Most participants (74.5%, n = 146) never worked on a stroke floor; however, almost all (95.9%, n = 188) cared for a stroke patient in the past. Most participants (65.3%, n = 128) reported receiving prelicensure stroke education, and 98.5% (n = 193) received postlicensure stroke education. Acute Stroke Management Questionnaire total scores ranged from 93 to 133 (mean [SD], 117.35 [8.15]). Most participants scored in the good stroke knowledge range for all 3 ASMaQ domains and total ASMaQ score. CONCLUSION: The online delivery of the ASMaQ was successful in testing nurses' stroke knowledge, and nurses were shown to have good stroke knowledge. Future initiatives should focus on discerning whether certain nurse characteristics predict higher or lower levels of stroke knowledge to help inform educational initiatives to improve IHS outcomes.

RESUMO

Single exon duplications account for disease in a minority of Duchenne muscular dystrophy patients. Exon skipping in these patients has the potential to be highly therapeutic through restoration of full-length dystrophin expression. We conducted a 48-week open label study of casimersen and golodirsen in 3 subjects with an exon 45 or 53 duplication. Two subjects (aged 18 and 23 years) were non-ambulatory at baseline. Upper limb, pulmonary, and cardiac function appeared stable in the 2 subjects in whom they could be evaluated. Dystrophin expression increased from 0.94 % ±0.59% (mean±SD) of normal to 5.1% ±2.9% by western blot. Percent dystrophin positive fibers also rose from 14% ±17% at baseline to 50% ±42% . Our results provide initial evidence that the use of exon-skipping drugs may increase dystrophin levels in patients with single-exon duplications.

RESUMO

OBJECTIVE: To investigate whether frail elderly people with atrial fibrillation (AF) who are currently using a vitamin K antagonist (VKA) should be switched to a direct-acting oral anticoagulant (DOAC). DESIGN: Randomized clinical trial. METHODS: 662 frail elderly AF patients were switched to a DOAC, and 661 patients continued their VKA. The primary endpoint was a major or clinically relevant non-major bleeding during 1 year of follow-up. Secondary endpoints included thrombo-embolic events. RESULTS: The mean age of the included patients was 83 years. In the 'switch to DOAC arm', 101 bleeding events (15.3%) occurred and in the 'continue with VKA arm', 62 bleeding events (9.4%); an increase of 69% more bleeding events (P-value 0.001). The number of thrombo-embolic events was not significantly different between both groups. CONCLUSION: Switching from a VKA to a DOAC in frail elderly people with AF leads to 69% more bleeding, without a difference in thrombo-embolic events.

RESUMO

Importance: The adverse effects of climate change are now apparent, disproportionately affecting marginalized and vulnerable populations and resulting in urgent worldwide calls to action. Health professionals occupy a critical position in the response to climate change, including in climate mitigation and adaptation, and their professional expertise and roles as health messengers are currently underused in the society-wide response to this crisis. Observations: Clinical and public health professionals have important roles and responsibilities, some of which are shared, that they must fill for society to successfully mitigate the root causes of climate change and build a health system that can reduce morbidity and mortality impacts from climate-related hazards. When viewed through a preventive framework, the unique and synergizing roles and responsibilities provide a blueprint for investment in climate change-related prevention (primary, secondary, and tertiary), capacity building, education, and training of the health workforce. Substantial investment in increasing the competence and collaboration of health professionals is required, which must be undertaken in an urgent, coordinated, and deliberate manner. Conclusions and Relevance: Exceptional collaboration, knowledge sharing, and workforce capacity building are essential to tackle the complex ways in which climate change threatens health. This framework serves as a guide for health system leaders, education institutions, policy planners, and others seeking to create a more resilient and just health system.

RESUMO

PURPOSE: This single-arm prospective cohort study aimed to evaluate the feasibility and utility of in-home body weight support harness system (BWSS) use in children treated for spinal muscular atrophy (SMA). METHODS: Individuals with 2 or 3 copies of SMN2 who received pharmacotherapeutic treatment, had head control, and weight <50lbs were enrolled. Families were provided a BWSS and documented use. Motor outcome assessments were completed at baseline, month 3 and month 6. Families provided feedback in an end of study survey. RESULTS: All 32 participants (2.9 (SD 1.9) yrs), improved or remained stable on all outcomes. Average reported frequency of use was 4.1(2.3) hrs/week. Controlling for other covariates, frequency of use explained over 70% of the variability in change scores. Family feedback was overwhelmingly positive. CONCLUSION: Use of in-home BWSS is a safe, feasible and useful option to increase exercise dosage after treatment in SMA and may help optimize motor abilities. TRIAL REGISTRATION: Study registered with: Clinicaltrials.gov Clinicaltrials.gov identifier: NCT05715749.
