Introduction. Octogenarian and nonagenarian patients constitute a progressively growing age group. Inguinal hernia is a pathology that increases with age. This study aims to understand the surgical outcomes of inguinal herniorrhaphy in patients over 80 years of age. Methods. A systematic review of PubMed, Embase, and Google Scholar was conducted following PRISMA guidelines. Studies reporting the incidence of complications and mortality after inguinal herniorrhaphy in octogenarian and nonagenarian patients were included. The proportion of patients with complications after inguinal herniorrhaphy was calculated based on the data presented, with its respective 95% confidence interval. Results. Fourteen studies reported a total of 19,290 patients, among whom a cumulative incidence of surgical site infection of 0.5 (95% CI 0.460 ­ 0.678), seroma of 8.7% (95% CI 6.212 ­ 11.842), hematoma of 2.6% (95% CI 2.397 ­ 2.893), chronic pain 2.1% (95% CI 0.778 ­ 4.090), recurrence 1.2% (95% CI 0.425 ­ 2.284), and morbidity 14.7% (95% CI 9.525 ­ 20.833) were found. Conclusion. Surgical wound complications, chronic pain, and recurrence in patients over 80 years of age undergoing inguinal herniorrhaphy are comparable to those in the general population.

Cost-effectiveness and health impact of screening and treatment of Mycobacterium tuberculosis infection among formerly incarcerated individuals in Brazil: a Markov modelling study.

BACKGROUND: Individuals who were formerly incarcerated have high tuberculosis incidence, but are generally not considered among the risk groups eligible for tuberculosis prevention. We investigated the potential health impact and cost-effectiveness of Mycobacterium tuberculosis infection screening and tuberculosis preventive treatment (TPT) for individuals who were formerly incarcerated in Brazil. METHODS: Using published evidence for Brazil, we constructed a Markov state transition model estimating tuberculosis-related health outcomes and costs among individuals who were formerly incarcerated, by simulating transitions between health states over time. The analysis compared tuberculosis infection screening and TPT, to no screening, considering a combination of M tuberculosis infection tests and TPT regimens. We quantified health effects as reductions in tuberculosis cases, tuberculosis deaths, and disability-adjusted life-years (DALYs). We assessed costs from a tuberculosis programme perspective. We report intervention cost-effectiveness as the incremental costs per DALY averted, and tested how results changed across subgroups of the target population. FINDINGS: Compared with no intervention, an intervention incorporating tuberculin skin testing and treatment with 3 months of isoniazid and rifapentine would avert 31 (95% uncertainty interval 14-56) lifetime tuberculosis cases and 4·1 (1·4-5·8) lifetime tuberculosis deaths per 1000 individuals, and cost US$242 per DALY averted. All test and regimen combinations were cost-effective compared with no screening. Younger age, longer incarceration, and more recent prison release were each associated with significantly greater health benefits and more favourable cost-effectiveness ratios, although the intervention was cost-effective for all subgroups examined. INTERPRETATION: M tuberculosis infection screening and TPT for individuals who were formerly incarcerated appears cost-effective, and would provide valuable health gains.

Use and Waste of Reconstituted Whole Blood Exchange Transfusions: An 11-year National Observational Study.

OBJECTIVES: To identify indications for exchange transfusions, assess the use and waste of exchange transfusion products (ie, reconstituted whole blood exchange transfusions), and determine nationwide distribution and prevalence of these transfusions in the Netherlands. STUDY DESIGN: All 9 neonatal intensive care units and 15 non-neonatal intensive care unit hospitals participated in this retrospective, observational, cohort study. We retrieved data on the indications for and use of all exchange transfusion products ordered by participating centers over an 11-year period. RESULTS: A total of 574 patients for whom 1265 products were ordered were included for analyses. Severe ABO (32.6%) and non-ABO (25.2%) immune hemolysis and subsequent hyperbilirubinemia were the most frequent indications. Rare indications were severe leukocytosis in Bordetella pertussis (2.1%) and severe anemia (1.5%). Approximately one-half of all ordered products remained unused. In 278 of 574 neonates (48.4%), ≥1 products were not used, of which 229 (82.7%) were due to the resolving of severe hyperbilirubinemia with further intensification of phototherapy. The overall prevalence of neonates who received an exchange transfusion was 14.6:100 000 liveborn neonates. CONCLUSIONS: A considerable proportion of products remained unused, and annually a limited number of patients are treated with an exchange transfusion in the Netherlands, highlighting the rarity of the procedure in the Netherlands.

Vascular smooth muscle cell-derived exosomes promote osteoblast-to-osteocyte transition via ß-catenin signaling.

Blood vessel growth and osteogenesis in the skeletal system are coupled; however, fundamental aspects of vascular function in osteoblast-to-osteocyte transition remain unclear. Our study demonstrates that vascular smooth muscle cells (VSMCs), but not endothelial cells, are sufficient to drive bone marrow mesenchymal stromal cell-derived osteoblast-to-osteocyte transition via ß-catenin signaling and exosome-mediated communication. We found that VSMC-derived exosomes are loaded with transcripts encoding proteins associated with the osteocyte phenotype and members of the WNT/ß-catenin signaling pathway. In contrast, endothelial cell-derived exosomes facilitated mature osteoblast differentiation by reprogramming the TGFB1 gene family and osteogenic transcription factors osterix (SP7) and RUNX2. Notably, VSMCs express significant levels of tetraspanins (CD9, CD63, and CD81) and drive the intracellular trafficking of exosomes with a lower membrane zeta potential than those from other cells. Additionally, the high ATP content within these exosomes supports mineralization mechanisms, as ATP is a substrate for alkaline phosphatase. Osteocyte function was further validated by RNA sequencing, revealing activity in genes related to intermittent mineralization and sonic hedgehog signaling, alongside a significant increase in TNFSF11 levels. Our findings unveil a novel role of VSMCs in promoting osteoblast-to-osteocyte transition, thus offering new insights into bone biology and homeostasis, as well as in bone-related diseases. Clinically, these insights could pave the way for innovative therapeutic strategies targeting VSMC-derived exosome pathways to treat bone-related disorders such as osteoporosis. By manipulating these signaling pathways, it may be possible to enhance bone regeneration and improve skeletal health in patients with compromised bone structure and function.

Economic Burden of Huntington's Disease: Analysis from a Brazilian Tertiary Care Perspective.

Background: Huntington's disease (HD) exerts significant impacts on individuals and families worldwide. Nevertheless, data on its economic burden in Brazil are scarce, revealing a critical gap in understanding the associated healthcare costs. Objective: This study was conducted at a tertiary neurology outpatient clinic in Brazil with the aim of assessing annual healthcare service utilization and associated costs for HD patients. Methods: We conducted a cross-sectional observational study involving 34 HD patients. A structured questionnaire was applied to collect data on direct medical costs (outpatient services, medications), non-medical direct costs (complementary therapies, mobility aids, home adaptations), and indirect costs (lost productivity, caregiver costs, government benefits) over one year. Results: Significant economic impacts were observed, with average annual direct medical costs of $4686.82 per HD patient. Non-medical direct and indirect costs increased the financial burden, highlighting extensive resource utilization beyond healthcare services. Thirty-three out of 34 HD patients were unemployed or retired, and 16 relied on government benefits, reflecting broader socioeconomic implications. Despite the dataset's limitations, it provides crucial insights into the economic impact of HD on patients and the Brazilian public health system. Conclusions: The findings underscore the urgent need for a more comprehensive evaluation of the costs to inform governmental policies related to HD. Future research is needed to expand the data pool and develop a nuanced understanding of the economic burdens of HD to help formulate effective healthcare strategies for patients.

Tuberculosis treatment loss to follow-up in children exposed at home: A prospective cohort study.

Background: Loss to follow-up (LTFU) from tuberculosis (TB) treatment and care is a significant public health problem. It is important to understand what drives LTFU in children - a population whose treatment and management depend on an adult caregiver - to better provide support services to families affected by TB. Methods: We conducted a prospective cohort study of household contacts in Lima, Peru (2009-12). Using multilevel logistic regression analysis, we explored individual-level characteristics of children and their adult household members with TB disease to identify risk factors for LTFU among children initiated on treatment for TB. Results: A total of 154 child (0-14 years) household contacts were diagnosed with TB and initiated on treatment. While most (n = 133, 86.4%) had a successful outcome, 20 (13.0%) children were LTFU. Six (30.0%) children were LTFU within three months, nine (45.0%) between five to seven months, and three (15.0%) after seven months of treatment being initiated. In univariable analysis, children with index patients above 25 years of age had decreased odds of being LTFU (odds ratio = 0.26; 95% confidence interval = 0.08-0.84) compared to children with index patients 25 years or younger. Conclusions: In this cohort, more than 10% of children sick with TB who were exposed to the disease at home were LTFU. An integrated, family-centred TB prevention and management approach may reduce barriers to a child completing their course of TB treatment.

'Someone must do it': multiple views on family's role in end-of-life care - an international qualitative study.

Background: Family is a crucial social institution in end-of-life care. Family caregivers are encouraged to take on more responsibility at different times during the illness, providing personal and medical care. Unpaid work can be overburdening, with women often spending more time in care work than men. Objectives: This study explored multiple views on the family's role in end-of-life care from a critical perspective and a relational autonomy lens, considering gender in a socio-cultural context and applying a relational autonomy framework. It explored patients, relatives and healthcare providers' points of view. Design: This qualitative study was part of the iLIVE project, involving patients with incurable diseases, their relatives and health carers from hospital and non-hospital sites. Methods: Individual interviews of at least five patients, five relatives and five healthcare providers in each of the 10 participating countries using a semi-structured interview guide based on Giger-Davidhizar-Haff's model for cultural assessment in end-of-life care. Thematic analysis was performed initially within each country and across the complete dataset. Data sources, including researchers' field notes, were translated into English for international collaborative analysis. Results: We conducted 158 interviews (57 patients, 48 relatives and 53 healthcare providers). After collaborative analysis, five themes were identified across the countries: family as a finite care resource, families' active role in decision-making, open communication with the family, care burden and socio-cultural mandates. Families were crucial for providing informal care during severe illness, often acting as the only resource. Patients acknowledged the strain on carers, leading to a conceptual model highlighting socio-cultural influences, relational autonomy, care burden and feminisation of care. Conclusion: Society, health teams and family systems still need to better support the role of family caregivers described across countries. The model implies that family roles in end-of-life care balance relational autonomy with socio-cultural values. Real-world end-of-life scenarios do not occur in a wholly individualistic, closed-off atmosphere but in an interpersonal setting. Gender is often prominent, but normative ideas influence the decisions and actions of all involved.

Zika virus vertical transmission induces neuroinflammation and synapse impairment in brain cells derived from children born with Congenital Zika Syndrome.

Zika virus (ZIKV) infection was first reported in 2015 in Brazil as causing microcephaly and other developmental abnormalities in newborns, leading to the identification of Congenital Zika Syndrome (CZS). Viral infections have been considered an environmental risk factor for neurodevelopmental disorders outcome, such as Autism Spectrum Disorder (ASD). Moreover, not only the infection per se, but maternal immune system activation during pregnancy, has been linked to fetal neurodevelopmental disorders. To understand the impact of ZIKV vertical infection on brain development, we derived induced pluripotent stem cells (iPSC) from Brazilian children born with CZS, some of the patients also being diagnosed with ASD. Comparing iPSC-derived neurons from CZS with a control group, we found lower levels of pre- and postsynaptic proteins and reduced functional synapses by puncta co-localization. Furthermore, neurons and astrocytes derived from the CZS group showed decreased glutamate levels. Additionally, the CZS group exhibited elevated levels of cytokine production, one of which being IL-6, already associated with the ASD phenotype. These preliminary findings suggest that ZIKV vertical infection may cause long-lasting disruptions in brain development during fetal stages, even in the absence of the virus after birth. These disruptions could contribute to neurodevelopmental disorders manifestations such as ASD. Our study contributes with novel knowledge of the CZS outcomes and paves the way for clinical validation and the development of potential interventions to mitigate the impact of ZIKV vertical infection on neurodevelopment.

Implementing group care in Dutch and Surinamese maternity and child care services: the vital importance of addressing outer context barriers.

BACKGROUND: By addressing physical and psychosocial needs, group care (GC) improves health-related behaviours, peer support, parent-provider interactions and may improve birth outcomes. Hence, global implementation of GC is encouraged. Context analyses prior to implementation are vital to elucidate which local factors may support or hinder implementation. METHODS: Contextual analyses conducted in the Netherlands and Suriname were compared to identify the factors relevant to the implementability of GC as perceived by healthcare professionals (HCPs). 32 semi-structured interviews were conducted with Dutch and Surinamese healthcare professionals. Audio recordings were transcribed verbatim and coded using the Framework approach. The Consolidated Framework for Implementation Research guided the development of the interview guide and of the coding tree. RESULTS: Outer setting: Concerns regarding funding surfaced in both countries. Due to limited health insurance coverage, additional fees would limit accessibility in Suriname. In the Netherlands, midwives dreaded lower revenue due to reimbursement policies that favour one-on-one care. Inner setting: Appropriate space for GC was absent in one Dutch and three Surinamese facilities. Role division regarding GC implementation was clearer in the Netherlands than in Suriname. INNOVATION: HCPs from both countries expected increased social support, health knowledge among women, and continuity of care(r). Individuals/innovation deliverers: Self-efficacy and motivation emerged as intertwined determinants to GC implementation in both countries. Individuals/innovation recipients: Competing demands can potentially lower acceptability of GC in both countries. While Dutch HCPs prioritised an open dialogue with mothers, Surinamese HCPs encouraged the inclusion of partners. PROCESS: Campaigns to raise awareness of GC were proposed. Language barriers were a concern for Dutch but not for Surinamese HCPs. CONCLUSIONS: While the most striking differences between both countries were found in the outer setting, they trickle down and affect all layers of context. Ultimately, at a later stage, the process evaluation will show if those outer setting barriers we identified prior to implementation actually hindered GC implementation. Changes to the health care systems would ensure sustained implementation in both countries, and this conclusion feeds into a more general discussion: how to proceed when contextual analyses reveal barriers that cannot be addressed with the time and resources available.

Water level regime variation is a crucial driver for taxonomic, functional, and phylogenetic diversity in seasonally flooded tropical forests.

Floodplains contribute significantly to terrestrial ecosystem service provision but are also among the most vulnerable and degraded ecosystems worldwide. Heterogeneity in floodplain properties arises from variations in river-specific flood regimes, watershed characteristics, and valley morphology, influencing seasonally flooded forests' taxonomic, functional, and phylogenetic diversity. This study addresses persisting knowledge gaps in floodplain ecology, focusing on the seasonally dry tropics. We explore the relationships between flood regime, environmental conditions, vegetation composition, functional and phylogenetic diversity, and the impact of environmental variables on above-ground biomass (AGB) and ecological strategies. The study spans six rivers in southeastern Brazil's main river basins: Rio Grande and São Francisco. We identified five eco-units in each floodplain based on flooding regimes and surveyed six plots per eco-unit. We measured trees with DBH > 5 cm and collected functional traits, along with detailed soil, climate, and water level data. We calculated plot-level floristic composition, taxonomic, functional, and phylogenetic diversity, wood density, and AGB. Functional and phylogenetic dissimilarity were analyzed, and the effects of climate, soil, and hydrological variables were quantified using generalized linear mixed models. We show how flood frequency and duration affect floristic composition across the floodplains. Taxonomic and phylogenetic diversity responded to climate, soil, and hydrological variables, while functional diversity responded primarily to hydrological variables, emphasizing the role of environmental filtering. Hydrological seasonality, soil fertility, and flood regime emerged as key factors shaping community structure and ecological strategies in the studied seasonally flooded tropical forests. Plot-level AGB responded to phosphorus but not to climate or hydrological variables. The study also highlights functional and phylogenetic dissimilarities among eco-units and basins, indicating potential climate change impacts.

In situ simulation in the intensive care unit: A phenomenological study of staff experiences.

OBJECTIVE: To explore the experiences of clinical and non-clinical staff in an intensive care unit regarding the perceived benefits and drawbacks of using in situ simulation as a training tool. METHODS: A descriptive phenomenological qualitative study was conducted among clinical and nonclinical ICU personnel. Simulations and interviews were conducted until data saturation was achieved. The interviews were recorded, transcribed verbatim for analysis, and interpreted using the Colaizzi method. RESULTS: Ten participant interviews generated data saturation. ISS was found to be feasible and beneficial in the ICU, facilitating experiential and emotion-based learning in real-world environments. Eight result categories were identified: simulation benefits, simulation benefits in real conditions, scenario authenticity, interference with usual work, ISS sessions, high-fidelity generating affective bonding, ISS as knowledge reinforcement, and recommendations for improvement. The fundamental structure revealed that ISS is perceived as an authentic and emotionally impactful team simulation modality that promotes experiential learning, reflection, and care improvement opportunities within the complex sociotechnical system of the ICU. CONCLUSIONS: All interviewees considered ISS to be a feasible simulation tool that should be implemented in the ICU to improve knowledge and skills, thereby enhancing teamwork.

Anatomy education in low-resourced countries: What are challenges and effective and affordable educational strategies? A qualitative study.

PURPOSE: With limited means, resource-deprived countries must find ways to organize education to meet standards. Few reports exist about anatomical education in LLMICs. This study explores how anatomy teaching is sustained in countries with few resources and which affordable educational strategies are applied to uphold quality. METHODS: A mixed-methods study with anatomy teachers from public medical schools in low or lower-middle income countries (LLMICs) in Africa, Asia, Europe, and Latin-American was performed through survey via email combined with semi-structured online interview with teachers, exploring survey results at a deeper level. RESULTS: LLMICs available to be surveyed, 13 and 8 were found to respond to a written survey and oral interview invitation, face significant teaching challenges, primarily due to lack of funds. These are faculty shortages (low salaries and high student-to-teacher ratio) and inadequate infrastructure (internet, electricity, poor classroom conditions). Solutions were associated with didactic strategies (social media, e-learning, image-based learning, applied anatomy), expanding teaching capacity with less qualified and part-time faculty, student-organized education, and self-financing (teaching resources subsidized by teachers and students). Which was triking was teacher commitment despite difficult circumstances. Teachers propose better faculty management, increased anatomy staff recruitment, and collaboration with other institutions. CONCLUSIONS: Anatomical education in LLMIC is forced to adapt to the socio-economic context, rather than to trends in medical education worldwide. These adaptations are supported mainly by the teachers 'commitment.'

Does Catch-Up Growth Come with a Cognitive Cost? Cognitive Outcome and Growth Patterns in Growth Discordant Identical Twins.

OBJECTIVE: To determine whether it is the magnitude of early postnatal catch-up growth (CUG) in response to fetal growth restriction (FGR) or the FGR itself that negatively impacts cognitive outcome in a model of monochorionic twins discordant for fetal growth. STUDY DESIGN: This analysis is part of the LEMON study, a cohort study including all monochorionic twins with selective FGR aged 3 through 17 years. Growth measurements as documented by our primary care system were collected retrospectively. An age-appropriate neurodevelopmental test was performed generating a full-scale IQ (FSIQ). CUG at 2 years was calculated as (weight [kg] at 2 years-birth weight [kg]). We used a multivariable regression model investigating the association between FSIQ (outcome) and birth weight zscore, gestational age at birth and CUG at 2 years (predictors). Generalized estimating equations accounted for the fact that observations between cotwins are not independent. RESULTS: Median age at follow-up of the 46 included twin pairs was 11 (IQR 8-13) years. Birth weight z score and gestational age at birth were significantly associated with FSIQ, with ß-coefficients of 5.897 (95% CI 3.382-8.411), and 2.589 (95% CI 1.227-3.951), respectively (P < .0001). Adjusted for birth weight z score and gestational age, CUG in the first 2 years after birth was not significantly associated with FSIQ (ß-coefficient 0.108 [95% CI -1.373 to 1.590], P = .886). CONCLUSIONS: Our results, combining detailed growth measurements and neurodevelopmental follow-up in a discordant identical twin model, demonstrate that FGR itself rather than early postnatal CUG has negative consequences for cognitive development.

HIV-1 Integrase T218I/S Polymorphisms Do Not Reduce HIV-1 Integrase Inhibitors' Phenotypic Susceptibility.

The recently Food and Drug Administration (FDA)-approved cabotegravir (CAB) has demonstrated efficacy as an antiretroviral agent for HIV treatment and prevention, becoming an important tool to stop the epidemic in the United States of America (USA). However, the effectiveness of CAB can be compromised by the presence of specific integrase natural polymorphisms, including T97A, L74M, M50I, S119P, and E157Q, particularly when coupled with the primary drug-resistance mutations G140S and Q148H. CAB's recent approval as a pre-exposure prophylaxis (PrEP) may increase the number of individuals taking CAB, which, at the same time, could increase the number of epidemiological implications. In this context, where resistance mutations, natural polymorphisms, and the lack of drug-susceptibility studies prevail, it becomes imperative to comprehensively investigate concerns related to the use of CAB. We used molecular and cell-based assays to assess the impact of T218I and T218S in the context of major resistance mutations G140S/Q148H on infectivity, integration, and resistance to CAB. Our findings revealed that T218I and T218S, either individually or in combination with G140S/Q148H, did not significantly affect infectivity, integration, or resistance to CAB. Notably, these polymorphisms also exhibited neutrality concerning other widely used integrase inhibitors, namely raltegravir, elvitegravir, and dolutegravir. Thus, our study suggests that the T218I and T218S natural polymorphisms are unlikely to undermine the effectiveness of CAB as a treatment and PrEP strategy.

Evaluation of four chatbots in autoimmune liver disease: A comparative analysis.

INTRODUCTION AND OBJECTIVES: Autoimmune liver diseases (AILDs) are rare and require precise evaluation, which is often challenging for medical providers. Chatbots are innovative solutions to assist healthcare professionals in clinical management. In our study, ten liver specialists systematically evaluated four chatbots to determine their utility as clinical decision support tools in the field of AILDs. MATERIALS AND METHODS: We constructed a 56-question questionnaire focusing on AILD evaluation, diagnosis, and management of Autoimmune Hepatitis (AIH), Primary Biliary Cholangitis (PBC), and Primary Sclerosing Cholangitis (PSC). Four chatbots -ChatGPT 3.5, Claude, Microsoft Copilot, and Google Bard- were presented with the questions in their free tiers in December 2023. Responses underwent critical evaluation by ten liver specialists using a standardized 1 to 10 Likert scale. The analysis included mean scores, the number of highest-rated replies, and the identification of common shortcomings in chatbots performance. RESULTS: Among the assessed chatbots, specialists rated Claude highest with a mean score of 7.37 (SD = 1.91), followed by ChatGPT (7.17, SD = 1.89), Microsoft Copilot (6.63, SD = 2.10), and Google Bard (6.52, SD = 2.27). Claude also excelled with 27 best-rated replies, outperforming ChatGPT (20), while Microsoft Copilot and Google Bard lagged with only 6 and 9, respectively. Common deficiencies included listing details over specific advice, limited dosing options, inaccuracies for pregnant patients, insufficient recent data, over-reliance on CT and MRI imaging, and inadequate discussion regarding off-label use and fibrates in PBC treatment. Notably, internet access for Microsoft Copilot and Google Bard did not enhance precision compared to pre-trained models. CONCLUSIONS: Chatbots hold promise in AILD support, but our study underscores key areas for improvement. Refinement is needed in providing specific advice, accuracy, and focused up-to-date information. Addressing these shortcomings is essential for enhancing the utility of chatbots in AILD management, guiding future development, and ensuring their effectiveness as clinical decision-support tools.

Characterisation and traceability of extra virgin olive oil and table olive of Azapa variety marketed in Chile using Microsatellite Molecular Markers / Caracterización y trazabilidad de aceite de oliva virgen extra y aceituna de mesa de la variedad Azapa comercializados en Chile mediante marcadores moleculares microsatélites

Chile has two certified origin olive products: Extra-Virgin Olive Oil (EVOO) from Huasco valley and the Azapa variety table olive from the Azapa valley. However, efficient methodologies are needed to determine the varieties and raw materials involved in the end products. In this study, we assessed the size of alleles from ten microsatellites in 20 EVOOs and in leaves and fruits of 16 olive varieties cultivated in Chile to authenticate their origins. The identification of varieties relied on specific allele sizes derived from microsatellites markers UDO99-011 and DCA18-M found in leaves and fruit mesocarp. While most Chilean single-variety EVOOs matched the variety declared on the label, inconsistencies were observed in single-variety EVOOs containing multiple varieties. Our findings confirm that microsatellites serve as a valuable as diagnostic tools for ensuring the quality control of Geographical Indication certification for Azapa olives and EVOO with Designation of Origin from Huasco.

Chile cuenta con dos productos de oliva de origen certificado: El aceite de oliva virgen extra (AOVE) del valle del Huasco y la aceituna de mesa de la variedad Azapa del valle de Azapa. Sin embargo, se necesitan metodologías eficientes para determinar las variedades y materias primas involucradas en los productos finales. En este estudio, evaluamos el tamaño de los alelos de diez microsatélites en 20 AOVEs y en hojas y frutos de 16 variedades de aceituna cultivadas en Chile para autentificar sus orígenes. La identificación de las variedades se basó en los tamaños alélicos específicos derivados de los marcadores microsatélites UDO99-011 y DCA18-M encontrados en las hojas y el mesocarpio de los frutos. Aunque la mayoría de los AOVEs chilenos monovarietales coincidían con la variedad declarada en la etiqueta, se observaron incoherencias en los AOVEs monovarietales que contenían múltiples variedades. Nuestros hallazgos confirman que los microsatélites sirven como valiosas herramientas de diagnóstico para asegurar el control de calidad de la certificación de Indicación Geográfica para aceitunas de Azapa y AOVE con Denominación de Origen de Huasco.

Survey-Based Assessment of the Quality of Reporting Guidelines of Carotid Artery Stenosis.

BACKGROUND: No evaluation of the quality of different carotid guidelines using validated scales has been performed to date. The present study aims to analyze 3 carotid stenosis guidelines, apprizing their quality and reporting using validated tools. METHODS: A survey-based assessment of the quality of the European Society for Vascular Surgery (ESVS) 2023, European Stroke Organisation (ESO) 2021, and the Society for Vascular Surgery (SVS) 2021 carotid stenosis guidelines, was performed by 43 vascular surgeons, cardiologists, neurologist or interventional radiologists using 2 validated appraisal tools for quality and reporting guidelines, the AGREE II instrument and the RIGHT statement. RESULTS: Using the AGREE II tool, the ESVS, SVS, and ESO guidelines had overall quality scores of 87.3%, 79.4%, and 82.9%, respectively (P = 0.001) The ESVS and ESO had better scores in the scope and purpose domain, and the SVS in the clarity of presentation domain. In the RIGHT statement, the ESVS, SVS, and ESO guidelines had overall quality scores of 84.0.7%, 74.3%, and 79.0%, respectively (P = 0.001). All 3 guidelines stood out for their methodology for search of evidence and formulating evidence-based recommendations. On the contrary, were negatively evaluated mostly in the cost and resource implications in formulating the recommendations. CONCLUSIONS: The 2023 ESVS carotid stenosis guideline was the best evaluated among the 3 guidelines, with scores over 5% higher than the other 2 guidelines. Efforts should be made by guideline writing committees to take the AGREE II and RIGHT statements into account in the development of future guidelines to produce high-quality recommendations.

The growzen™ buddy smartphone app to improve adherence in patients receiving recombinant human growth hormone therapy: a retrospective observational study in Argentina.

Introduction: This study in Argentina evaluated the impact of the growzen™ buddy smartphone app on adherence to recombinant human growth hormone (r-hGH) treatment. Methods: The adherence data, invitation dates with a link to the app, app activation dates, and height measurements entered were extracted from the growzen™ digital health ecosystem. Patients with 12 months of adherence data, aged ≥2 years at treatment start, and aged <19 years were selected both before and after app implementation. Mean adherence was classified as optimal (≥85%) versus suboptimal (<85%). Adherence before and after implementation and the pre-post effect on adherence were assessed. Results: Data for 830 patients were available. Prior to app implementation, the proportion of patients with optimal adherence was 68% (n = 348/515). Following the app implementation, out of 315 patients, 302 (96%) received an invitation with a link to the app, 225 (71%) activated their account, and 127 (40%) entered height data in the first year. There was a significant early increase in the proportion of patients with optimal adherence following implementation: 82% (n = 258/315), p < 0.001. After implementation, the proportion of patients with optimal adherence included 80% (n = 78/98) of those with an active account who did not enter height measurements and 89% (n = 113/127) of those who did. There was a significant and positive pre-post app effect on adherence (p < 0.01) in patients with an active account. Discussion: Our results show that using the growzen™ buddy app has a rapid and positive impact on adherence to r-hGH treatment, and patients who were more engaged with the app demonstrated better adherence.
