RESUMEN

BACKGROUND: Increasing representation in clinical trials is a priority for the National Cancer Institute and Children's Oncology Group (COG). Our survey of COG-affiliated institutions revealed that many sites have insufficient processes and resources to enroll children whose parents use languages other than English (LOE). We describe reported barriers and facilitators to enrolling children in clinical trials when parents use LOE and propose opportunities for improvement. PROCEDURES: We sent a 20-item survey to COG-affiliated institutions. Five items allowed respondents to expand on replies to questions about (a) local institutional review board (IRB) requirements regarding translation of consent documents, (b) contributors to provider discomfort consenting parents who use LOE, (c) available language services and resources, and (d) barriers to enrolling children whose parents use LOE or offer ideas about approaches to improvements. Two pairs of researchers independently coded free-text responses and compared results for concordance. RESULTS: A total of 139 (N = 230; 60%) institutions returned the survey. Respondents were mainly physician principal investigators (n = 79/139; 57%) at the United States sites (n = 118/139; 85%) serving less than 100 newly diagnosed children per year (n = 99/139, 71%). They described challenges at multiple levels. Proposed approaches to improvements included centralized provision of translated materials and video educational materials in various languages, and collaborating with IRBs on regulatory processes that protect families and facilitate equitable clinical trial access. CONCLUSIONS: Clinical trial consortia, such as COG, face challenges in enrolling representative samples. Further research is required to design and implement multilevel interventions to ensure equitable access for all, regardless of language used, and mitigate disparate research participation.

RESUMEN

Rectal swabs (122) from pediatric patients were analyzed by polymerase chain reaction (PCR) for the detection of EPEC and STEC. STEC isolates were tested for the presence of stx1, stx2, eae, saa and ehxA. All eae-positive samples were tested for the presence of bfpA, and antigen O was determined using the agglutination test. Int1 and Int2 were detected to identify the presence of integrons class 1 and 2, respectively. Escherichia coli was detected in 68% of the samples, of which 18.8% were STEC (2.45%) and EPEC (16.3%). Serogroups STEC O145 and EPEC O130, O113 and O157 were observed, while three strains were non-typable. None of the EPEC strains carrying tbfpA and class 1 and 2 integrons was detected in any of the samples. The results obtained are important considering the virulence profiles found in the isolated EPEC and STEC strains and the serogroups associated with disease in humans.

RESUMEN

A great number of free radicals have a negative impact on the human body, and an increased interest in the identification of new natural molecules with antioxidant properties has emerged due to concerns about synthetic antioxidants. Here, the antioxidant effect of four exo-polysaccharides (EPS) extracts obtained from submerged cultivation of Nothophellinus andinopatagonicus and Pseudoinonotus crustosus (N and P, respectively) in two culture media (M1 and M2) at 2 concentrations (100 and 250 µg/ml) was studied; then, its relation with the chemical composition of the EPS was evaluated. To assess the antioxidant activities of the extracts, several in vitro assays were performed: DPPH and ABTS radical scavenging, ferric-reducing antioxidant power, chelating ability on ferrous ions, and inhibition of the lipid peroxidation. The concentrations tested here were much lower than those reported in previous works. Despite variations in chemical composition and monosaccharide profiles among the extracts, all demonstrated antioxidant activity, although the type of activity differed; only P-M1 exhibited a good antioxidant activity across all assays. This extract contained the highest proportion of phenolic compounds, and also displayed the highest radical scavenging activity. Although the utilization of polysaccharides as functional food ingredients remains limited, we propose P-M1 as a promising candidate for a nutraceutical product. Additionally, a formulation could be made with a combination of extracts to create an antioxidant-rich supplement. Additional research is needed to confirm our findings in a cellular environment and to elucidate the mechanisms that drive their antioxidant activities, ultimately facilitating their development and utilization as nutraceutical products.

RESUMEN

Rationale: PSMA-targeting radioligand therapy (PSMA-RLT) has shown promise in metastatic castration-resistant prostate cancer (mCRPC), particularly in PSMA-avid tumours. However, predicting response remains challenging. Preclinical data suggests aberrant p53-signalling as a predictor of poor response. Methods: The patient population of this pre-planned retrospective cohort study consists of 96 patients with mCRPC who underwent treatment with PSMA-RLT and were molecularly profiled by whole-genome sequencing and or targeted next-generation sequencing. Response to PSMA-RLT was assessed per molecular subtype, including TP53-mutational status. Results: Patients with TP53 loss-of-function alterations had a shorter median progression-free survival (3.7 versus 6.2 months, P<0.001), a lower median PSA change (-55% vs. -75%, P=0.012) and shorter overall survival from initiation of PMSA-RLT (7.6 vs. 13.9 months, P=0.003) compared to TP53-wildtype patients. Pathogenic alterations in AR, MYC, BRCA1, or BRCA2 as well as in genes linked to the PI3K or MAPK pathways or genes involved in homologous recombination repair, were not associated with response. Only lactate dehydrogenase was, alongside TP53-status, significantly associated with response. Transcriptome analysis of 21 patients, identified six p53 signalling genes whose low expression was associated to a shorter progression-free survival (P<0.05). Conclusion: TP53 loss-of-function may serve as a prognostic factor for PSMA-RLT outcomes in patients with mCRPC.

RESUMEN

CONTEXT: Robust associations have been identified between fertility during adolescence and the disablement process, including pathologies, impairments, functional limitations and disability. Limited theoretical or empirical research considers how and why such relationships exist generally or with the individual associated components of disablement. OBJECTIVE: To consolidate and critically evaluate literature to describe testable, theory-based hypotheses to guide future research on the mechanisms by which fertility during adolescence contributes to disablement. METHODS: Targeted literature review of research from diverse global settings contextualised in two well-accepted theoretical frameworks in life-course epidemiology: the cumulative risk model and the critical period approach. RESULTS: Five hypothesised causal pathways linking adolescent fertility to disablement in later life are described: 1) Causal relationship initiated by fertility during adolescence; 2) Common cause(s) for both, such as adverse childhood experiences; 3) Contributing cause(s) to adolescent fertility; 4) Interaction between adolescent fertility and other risk factors; and 5) Critical period effects unique to adolescence. Most research on the topic is on pathologies versus functional limitations and disability. CONCLUSION: We highlight promising research avenues to inform future research and interventions on adolescent fertility and the disablement process. This work provides theoretical clarity, identifies research gaps, and offers hypotheses-testing opportunities for future research.

RESUMEN

OBJECTIVES: To evaluate the association between adolescent and young adult (AYA) breast cancer (BC) and the adverse pregnancy outcomes of preterm birth, small for gestational age birth, cesarean delivery, and preeclampsia, and the effect of fertility treatment on this association. METHODS: Population-based cohort study with universal coverage health data for Ontario, Canada. BC was identified from the Ontario Cancer Registry. All births >220 weeks gestation between April 2006 to March 2018 were included. Modified Poisson regression generated risk ratios between AYA BC and adverse pregnancy outcomes, adjusted for maternal characteristics. Models were stratified by fertility treatment. RESULTS: Among 1 189 980 deliveries, 474 mothers had AYA BC history (exposed), while 1 189 506 had no cancer history (unexposed). AYA BC was associated with cesarean delivery (adjusted risk ratio [aRR] 1.26; 95% CI 1.14-1.39). There was no association between AYA BC and other adverse outcomes. Modelling cesarean delivery subtypes, AYA BC was associated with increased risk of planned (aRR 1.27; 95% CI 1.08-1.49) and unplanned cesarean delivery (aRR 1.41; 95% CI 1.20-1.66). An increased risk of cesarean delivery in exposed persisted among singleton pregnancies (aRR 1.27; 95% CI 1.15-1.41), but not in models stratified by mode of conception (fertility treatment: aRR 1.07; 95% CI 0.84-1.36; unassisted conception: aRR 1.30; 95% CI 1.16-1.46). CONCLUSIONS: A history of AYA BC did not confer an elevated risk of adverse pregnancy outcomes, except for planned and unplanned cesarean delivery. The risk of adverse pregnancy outcomes does not appear to be an indication for delayed pregnancy after AYA BC diagnosis.

RESUMEN

BACKGROUND/AIMS: Due to rapid metabolic and growth rates during the first two years of life, the nutritional needs of young children are high. Given the small portion sizes consumed by children between the ages of 6 and 24 months, it is necessary to improve diets to meet the nutritional needs of this age group. Therefore, the analysis of lysine content is an important parameter in the evaluation of enriched foods. METHODS: The utilization of an enzymatic sensor employing lysine-α-oxidase (LOx) as a biorecognition element represents an alternative to the existing methods. This sensor was optimized for quantifying the lysine content in flour mixtures: Quinoa-Lablab purpureus rye - Lablab purpureus, and pole beans - Lablab purpureus, with a maximum ratio of 85g/100g. RESULTS: The addition of lablab purpureus significantly increased the lysine concentration in the enriched samples. When 30 percent was substituted in quinoa, it reached a 143 percent increase. And when 15 percent was substituted in the rye flour, the final concentration of this amino acid increased by 64 percent. In order to quantify the lysine concentration, it was necessary to optimize various parameters during the use of the sensor, e.g. a potentiometric signal was detected upon the depletion of oxygen present during the oxidation of lysine in the samples, and the sensor response was recorded at 2 s. This was possible due to the modification of the pH and the thickness of the membrane. The oxidation of lysine is catalyzed by LOx using molecular oxygen as the electron acceptor. The corresponding acidic compounds and hydrogen peroxide were formed in the reaction medium. CONCLUSION: It was possible to increase and verify the concentration of lysine in all the flours tested through the use of the biosensor, which turned out to be a valid method for controlling the nutritional quality of flours.

RESUMEN

BACKGROUND: The loss of laryngeal function affects breathing, swallowing, and voice, thus severely compromises quality of life. Laryngeal transplantation has long been suggested as a solution for selected highly affected patients with complete laryngeal function loss. OBJECTIVE: To obtain insights regarding the advantages, weaknesses, and limitations of this procedure and facilitate future advances, we collected uniform data from all known laryngeal transplants reported internationally. METHODOLOGY: A case series. Patients were enrolled retrospectively by each institutional hospital or clinic. Eleven patients with complete loss of laryngeal function undergoing total laryngeal transplantation between 1998 and 2018 were recruited. RESULTS: After a minimum of 24 months follow-up, three patients had died (27%), and there were two graft explants in survivors, one total and one partial, due to chronic rejection. In the remaining cases, voice was functional in 62.5% and 50% achieved decannulation. Swallowing was initially restricted, but only one patient was gastrostomy-dependent by 6 months and all had normal or near-normal swallowing by the end of year two after transplantation. Median follow-up was 73 months. Functional (voice, swallowing, airway) recovery peaked between 12 and 24 months. CONCLUSIONS: Laryngeal transplantation is a complex procedure with significant morbidity. Significant improvements in quality of life are possible for highly selected individuals with end-stage laryngeal disorders, including laryngeal neoplasia, but further technical and pharmacological developments are required if the technique is to be more widely applicable. An international registry should be created to provide better quality pooled data for analysis of outcomes of any future laryngeal transplants. LEVEL OF EVIDENCE: IV Laryngoscope, 2024.

RESUMEN

In our pursuit of a fulfilling and contented life, the study of well-being has emerged as a fundamental field of research. Higher levels of well-being are associated with better mental health outcomes. Individuals with better mental health might possess the personal resources necessary to set and pursue meaningful goals, maintain positive expectations, and overcome adversities. We aim to explore the positive relationship between well-being (hedonic, psychological, and social) and dispositional hope. We suggest that mental health acts as a mediator in this relationship, since improved mental health can create a conducive environment for the development and maintenance of dispositional hope. Data were collected using an e-survey through social media during the last quarter of 2022. The hypothesis of this study was tested using mediation analysis. The sample was composed of 471 participants (85.4% female) with a mean age of 47.72 ± 11.86 years. Participants were mainly workers (88.6%), followed by pensioners (6.8%), university students (2.5%), and unemployed (2.1%). Results revealed that well-being was positively and significantly associated with dispositional hope. Additionally, well-being presented a significant and positive relationship with mental health, which, in turn, also presented a significant and positive relationship with dispositional hope. Finally, using the Hayes process macro for SPSS, we found that mental health mediates the relationship between well-being and dispositional hope. Our findings reinforce the conceptual frameworks that consider well-being and mental health as key contributors to a resilient and optimistic mindset. Interventions that aim to cultivate positive affect, facilitate personal growth, and foster supportive social environments might help improve mental health outcomes.

RESUMEN

This population-based cohort evaluated the association between endometriosis and severe maternal morbidity (SMM), and the mediating effect of infertility and fertility treatment. Included were all singleton deliveries in Ontario between 2006 and 2014. Modified Poisson regression generated adjusted relative risks. Mediation analysis estimated the direct effect of endometriosis and indirect effect through infertility and mode of conception. 787 449 deliveries were included (19 099, 2.4% with endometriosis). SMM occurred in 29.0 per 1000 deliveries among women with endometriosis, in contrast to 18.2 per 1000 deliveries among those without endometriosis-corresponding to an adjusted relative risk of SMM of 1.43 (95% CI 1.31-1.56). Mediation analysis demonstrated that the effect of endometriosis on SMM was independent of infertility or fertility treatment. We conclude that SMM in women with endometriosis appears to be due to the disease itself and not to infertility or related treatments.

RESUMEN

Purpose: This research proposes an adapted version of Business Model Canvas (BMC) as a potential strategic tool for the design of the business model of Higher Education Institutions (HEIs). In the context of fifth-generation universities, the University-Model Canvas (Unicanvas) offers a solution to some limitations of traditional strategic tools. Unicanvas aims to be a critical visual and dynamic tool to address the new challenges faced by universities such as internationalization, digitalization, sustainability, and corporate social responsibility. Research methods/Approach: We adapt the strategic building blocks, in which some of the BMC blocks have been renamed and an achievement block has been added. We reflect theoretically on the peculiarities of each block in the context of universities to explain the versatility of the tool for designing university business models tailored to different value propositions and for various beneficiaries. Findings and implications: Unicanvas offers universities the flexibility and dynamism to adapt their different business models to various forms of value creation that arise from their growing number of beneficiaries, missions, and the new trends and challenges they face.. We conclude that using this participatory,, dynamic, intuitive, and flexible strategic tool will facilitate the holistic design of the business model of these institutions.

RESUMEN

Climate change-induced hazards, such as drought, threaten forest resilience, particularly in vulnerable regions such as the Mediterranean Basin. Maritime pine (Pinus pinaster Aiton), a model species in Western Europe, plays a crucial role in the Mediterranean forest due to its genetic diversity and ecological plasticity. This study characterizes transcriptional profiles of scion and rootstock stems of four P. pinaster graft combinations grown under well-watered conditions. Our grafting scheme combined drought-sensitive and drought-tolerant genotypes for scions (GAL1056: drought-sensitive scion; and Oria6: drought-tolerant scion) and rootstocks (R1S: drought-sensitive rootstock; and R18T: drought-tolerant rootstock). Transcriptomic analysis revealed expression patterns shaped by genotype provenance and graft combination. The accumulation of differentially expressed genes (DEGs) encoding proteins, involved in defense mechanisms and pathogen recognition, was higher in drought-sensitive scion stems and also increased when grafted onto drought-sensitive rootstocks. DEGs involved in drought tolerance mechanisms were identified in drought-tolerant genotypes as well as in drought-sensitive scions grafted onto drought-tolerant rootstocks, suggesting their establishment prior to drought. These mechanisms were associated with ABA metabolism and signaling. They were also involved in the activation of the ROS-scavenging pathways, which included the regulation of flavonoid and terpenoid metabolisms. Our results reveal DEGs potentially associated with the conifer response to drought and point out differences in drought tolerance strategies. These findings suggest genetic trade-offs between pine growth and defense, which could be relevant in selecting more drought-tolerant Pinus pinaster trees.

RESUMEN

BACKGROUND: Persons who speak languages other than English are underrepresented in clinical trials, likely in part because of inadequate multilevel resources. We conducted a survey of institutions affiliated with the Children's Oncology Group (COG) to characterize current research recruitment practices and resources regarding translation and interpretation services. METHODS: In October 2022, a 20-item survey was distributed electronically to institutions affiliated with COG to assess consent practices and resources for recruiting participants who speak languages other than English to COG trials. Descriptive statistics were used to summarize responses; responses were compared by institution size and type as well as respondent role. RESULTS: The survey was sent to 230 institutions, and the response rate was 60% (n = 139). In total, 60% (n = 83) of those respondents had access to short-form consent forms. Full consent form translation was required at 50% of institutions, and 12% of institutional review boards restricted use of centrally translated consent forms. Forty-six percent (n = 64) of institutions reported insufficient funding to support translation costs; 19% (n = 26) had access to no-cost translation services. Forty-four percent (n = 61) were required to use in-person interpreters for consent discussions; the most frequently cited barrier (56%) to obtaining consent was lack of available in-person interpreters. Forty-seven percent (n = 65) reported that recruiting persons who speak languages other than English to clinical trials was somewhat or very difficult. CONCLUSIONS: Institutions affiliated with COG face resource-specific challenges that impede recruitment of participants who speak languages other than English for clinical trials. These findings indicate an urgent need to identify strategies aimed at reducing recruitment barriers to ensure equitable access to clinical trials.

RESUMEN

BACKGROUND: Infertility is a marginalized sexual and reproductive health issue in low-resource settings. Globally, millions are affected by infertility, but the lack of a universal definition makes it difficult to estimate the prevalence of infertility at the population level. Estimating the prevalence of infertility may inform targeted and accessible intervention, especially for a resource-limited country like Ethiopia. This study aims to estimate the prevalence of female infertility in Ethiopia using the Demographic and Health Survey (DHS) through two approaches: (i) the demographic approach and (ii) the current duration approach. METHODS: Data from 15,683 women were obtained through the 2016 Ethiopian DHS. The demographic approach estimates infertility among women who had been married/in a union for at least five years, had never used contraceptives, and had a fertility desire. The current duration approach includes women at risk of pregnancy at the time of the survey and determines their current length of time-at-risk of pregnancy at 12, 24, and 36 months. Logistic regression analysis estimated the prevalence of infertility and factors associated using the demographic approach. Parametric survival analysis estimated the prevalence of infertility using the current duration approach. All estimates used sampling weights to account for the DHS sampling design. STATA 14 and R were used to perform the statistical analysis. RESULTS: Using the demographic definition, the prevalence of infertility was 7.6% (95% CI 6.6-8.8). When stratified as primary and secondary infertility, the prevalence was 1.4% (95% CI 1.0-1.9) and 8.7% (95% CI 7.5-10.1), respectively. Using the current duration approach definition, the prevalence of overall infertility was 24.1% (95% CI 18.8-34.0) at 12-months, 13.4% (95% CI 10.1-18.6) at 24-months, and 8.8% (95% CI 6.5-12.3) at 36-months. CONCLUSION: The demographic definition of infertility resulted in a lower estimate of infertility. The current duration approach definition could be more appropriate for the early detection and management of infertility in Ethiopia. The findings also highlight the need for a comprehensive definition of and emphasis on infertility. Future population-based surveys should incorporate direct questions related to infertility to facilitate epidemiological surveillance.

RESUMEN

OBJECTIVE: Motivation for the study. Filling a knowledge gap regarding support groups for caregivers of children with multiple disabilities. Main findings. Support groups are valuable spaces for social support and learning for caregivers of children with multiple disabilities. They facilitate resilience and coping strategies following the birth of a child with multiple disabilities. They promote the participation and empowerment of caregivers of children with multiple disabilities to address access barriers and advocate for the fundamental rights of children. Implications. It is important to promote and support support groups for caregivers of children with multiple disabilities. To explore the perceived benefits of participating in a support group of caregivers of children with multiple disabilities. MATERIALS AND METHODS.: A qualitative study with a focused ethnographic approach was conducted from October 2022 to February 2023, in which we applied convenience sampling. We included 20 caregivers of children with multiple disabilities. Information was collected through participant observation, focus groups, and semi-structured interviews. Thematic analysis was performed by applying Braun and Clark's proposals. RESULTS.: The emerging themes were: social support network: integrating, informing, and helping each other; learning space: learning to take care and to take care of oneself; promoting empowerment: identifying and facing access barriers. CONCLUSIONS.: We found that the support group functions as a social support network provides information, reduces uncertainty, and facilitates coping and resilience after the birth and upbringing of a child with multiple disabilities. It is a space where one learns to care for and take care of oneself and where empowerment for the defense of the rights of children with disabilities is promoted.

RESUMEN

The psychological, social, and financial disabilities caused by infertility are significant for women, particularly those living in low- and middle-income countries such as Ethiopia. Although rehabilitation can be an important form of support for such women, infertility is frequently overlooked as a disability or potential target of rehabilitation interventions. This study aimed to determine what rehabilitation-related services and supports are available for women experiencing infertility in Ethiopia. We used an Interpretive Description design. We purposefully selected fourteen rehabilitation, medical, and policy service providers from diverse institutions across three geographical locations. We used semi-structured questions during our in-person and telephone interviews. The data were analyzed using reflexive thematic analysis with the assistance of NVivo. We identified five main themes, including (a) policies related to infertility, (b) the concept that disabilities are physically visible fails to recognize infertility, (c) the need for rehabilitation services for women with infertility, (d) the importance of wellness services for women experiencing infertility, and (e) the role of religion in rehabilitation services. In conclusion, it is essential to strengthen the policies around infertility, incorporate rehabilitation services in fertility care, and view infertility as a disabling condition for women who experience it in Ethiopia.

RESUMEN

Importance: A publicly funded fertility program was introduced in Ontario, Canada, in 2015 to increase access to fertility treatment. For in vitro fertilization (IVF), the program mandated an elective single-embryo transfer (eSET) policy. However, ovulation induction and intrauterine insemination (OI/IUI)-2 other common forms of fertility treatment-were more difficult to regulate in this manner. Furthermore, prior epidemiologic studies only assessed fetuses at birth and did not account for potential fetal reductions that may have been performed earlier in pregnancy. Objective: To examine the association between fertility treatment and the risk of multifetal pregnancy in a publicly funded fertility program, accounting for both fetal reductions and all live births and stillbirths. Design, Setting, and Participants: This population-based, retrospective cohort study used linked administrative health databases at ICES to examine all births and fetal reductions in Ontario, Canada, from April 1, 2006, to March 31, 2021. Exposure: Mode of conception: (1) unassisted conception, (2) OI/IUI, or (3) IVF. Main Outcomes and Measures: The main outcome was multifetal pregnancy (ie, a twin or higher-order pregnancy). Modified Poisson regression generated adjusted relative risks (ARRs) and derived population attributable fractions (PAFs) for multifetal pregnancies attributable to fertility treatment. Absolute rate differences (ARDs) were used to compare the era before eSET was promoted (2006-2011) with the era after the introduction of the eSET mandate (2016-2021). Results: Of all 1 724 899 pregnancies, 1 670 825 (96.9%) were by unassisted conception (mean [SD] maternal age, 30.6 [5.2] years), 24 395 (1.4%) by OI/IUI (mean [SD] maternal age, 33.1 [4.4] years), and 29 679 (1.7%) by IVF (mean [SD] maternal age, 35.8 [4.7] years). In contrast to unassisted conception, individuals who received OI/IUI or IVF tended to be older, reside in a high-income quintile neighborhood, or have preexisting health conditions. Multifetal pregnancy rates were 1.4% (95% CI, 1.4%-1.4%) for unassisted conception, 10.5% (95% CI, 10.2%-10.9%) after OI/IUI, and 15.5% (95% CI, 15.1%-15.9%) after IVF. Compared with unassisted conception, the ARR of any multifetal pregnancy was 7.0 (95% CI, 6.7-7.3) after OI/IUI and 9.9 (95% CI, 9.6-10.3) after IVF, with corresponding PAFs of 7.1% (95% CI, 7.1%-7.2%) and 13.4% (95% CI, 13.3%-13.4%). Between the eras of 2006 to 2011 and 2016 to 2021, multifetal pregnancy rates decreased from 12.9% to 9.1% with OI/IUI (ARD, -3.8%; 95% CI, -4.2% to -3.4%) and from 29.4% to 7.1% with IVF (ARD, -22.3%; 95% CI, -23.2% to -21.6%). Conclusions and Relevance: In this cohort study of more than 1.7 million pregnancies in Ontario, Canada, a publicly funded IVF program mandating an eSET policy was associated with a reduction in multifetal pregnancy rates. Nevertheless, ongoing strategies are needed to decrease multifetal pregnancy, especially in those undergoing OI/IUI.

RESUMEN

OBJECTIVE: To examine the association between menopause hormone therapy (MHT) and physical performance among women from the Canadian Longitudinal Study on Aging. STUDY DESIGN: Cross-sectional study of 12,506 postmenopausal Canadian women. MAIN OUTCOME MEASURES: Grip strength (kg), gait speed (m/s), timed up and go (s), chair rise (s), and balance (s) were assessed following standard procedures. The association between MHT and physical performance was evaluated using linear regression models adjusted for age, education, study site, smoking, alcohol consumption, body mass index, diabetes, hypertension, and hysterectomy. Sensitivity analyses were conducted according to age at study visit (<65 vs. ≥65 years), body mass index (<25 kg/m2 vs. ≥25 kg/m2), physical activity level (less vs. more active), duration and type of MHT, and time of starting MHT after menopause. RESULTS: Compared with those who never used MHT, prior or current use was associated with better performance on the timed up and go test (ß: -0.19; 95%CI: -0.28; -0.11) and faster gait speed (ß = 0.01, 95%CI = 0.00; 0.02). No association was found for grip strength, balance, and chair rise. Results did not change by body mass index, physical activity, or duration of MHT use. When stratified by age at study visit, the effect remained significant only in among those aged 65 years or more. Starting MHT <5 years after menopause was associated with better physical performance. CONCLUSIONS: MHT was associated with better physical performance in gait speed and timed up and go tests. The cross-sectional design of the study limits causal interpretation. Prospective studies are needed to confirm our results.

RESUMEN

Polariton canalization is characterized by intrinsic collimation of energy flow along a single crystalline axis. This optical phenomenon has been experimentally demonstrated at the nanoscale by stacking and twisting van der Waals (vdW) layers of α-MoO3, by combining α-MoO3 and graphene, or by fabricating an h-BN metasurface. However, these material platforms have significant drawbacks, such as complex fabrication and high optical losses in the case of metasurfaces. Ideally, it would be possible to canalize polaritons "naturally" in a single pristine layer. Here, we theoretically predict and experimentally demonstrate naturally canalized phonon polaritons (PhPs) in a single thin layer of the vdW crystal LiV2O5. In addition to canalization, PhPs in LiV2O5 exhibit strong field confinement ( λ p ~ λ 0 27 ), slow group velocity (0.0015c), and ultra-low losses (lifetimes of 2 ps). Our findings are promising for the implementation of low-loss optical nanodevices where strongly directional light propagation is needed, such as waveguides or optical routers.
