RESUMEN
The Genetic Counselling Outcome Scale (GCOS)-24 is a patient-reported outcome measure (PROM) developed and validated in the United Kingdom (UK). The aim of this study was to cross-culturally adapt GCOS-24 to Canadian Clinical Genetic Services (CGS). This was achieved through a qualitative study exploring whether the existing GCOS-24 maintains its intended meaning in a Canadian population and assessing whether GCOS-24 items could be better worded to meet the needs of members of families affected by genetic conditions in Canada. Thirteen participants were recruited from Canadian Patient Organizations supporting people and families affected by genetic conditions. Data were collected through semi-structured cognitive interviews, as these allow exploration of participants' comprehension, opinions, thoughts, and feelings regarding GCOS-24's instructions, response options, and the meaning/relevance of each item. Thematic analysis was utilized for data analysis, and an inductive approach to coding was followed to allow for themes to emerge from the data. Themes were organized in respect to their questionnaire item and further classified into their respective Empowerment dimension. The GCOS-24 instructions were found easy to understand by all thirteen participants. Although the response options were also found to be straightforward, the data suggest the questionnaire would benefit from the addition of a "non-applicable" option. Semantic validation of the GCOS-24 showed that items within the Cognitive Control and Emotional Regulation dimensions were found easy to understand by participants. However, items within the Decisional Control, Behavioural Control and Hope dimensions presented semantic difficulties. Participants provided feedback on syntactic changes to support understanding, and this feedback was used to develop a final Canadian-adapted version of GCOS-24, GCOS-Canada. This study provides the first step towards a valid, culturally adapted PROM for use in Canadian CGS service evaluation and research. GCOS-Canada would benefit from psychometric validation to ensure validity, reliability, responsiveness, minimal clinically important difference and internal consistency.
RESUMEN
INTRODUCTION: The COVID-19 pandemic resulted in significant healthcare reorganizations, potentially striking standard medical care. We investigated the impact of the COVID-19 pandemic on acute stroke care quality and clinical outcomes to detect healthcare system's bottlenecks from a territorial point of view. METHODS: Crossed-data analysis between a prospective nation-based mandatory registry of acute stroke, Emergency Medical System (EMS) records, and daily incidence of COVID-19 in Catalonia (Spain). We included all stroke code activations during the pandemic (March 15-May 2, 2020) and an immediate prepandemic period (January 26-March 14, 2020). Primary outcomes were stroke code activations and reperfusion therapies in both periods. Secondary outcomes included clinical characteristics, workflow metrics, differences across types of stroke centers, correlation analysis between weekly EMS alerts, COVID-19 cases, and workflow metrics, and impact on mortality and clinical outcome at 90 days. RESULTS: Stroke code activations decreased by 22% and reperfusion therapies dropped by 29% during the pandemic period, with no differences in age, stroke severity, or large vessel occlusion. Calls to EMS were handled 42 min later, and time from onset to hospital arrival increased by 53 min, with significant correlations between weekly COVID-19 cases and more EMS calls (rho = 0.81), less stroke code activations (rho = -0.37), and longer prehospital delays (rho = 0.25). Telestroke centers were afflicted with higher reductions in stroke code activations, reperfusion treatments, referrals to endovascular centers, and increased delays to thrombolytics. The independent odds of death increased (OR 1.6 [1.05-2.4], p 0.03) and good functional outcome decreased (mRS ≤2 at 90 days: OR 0.6 [0.4-0.9], p 0.015) during the pandemic period. CONCLUSION: During the COVID-19 pandemic, Catalonia's stroke system's weakest points were the delay to EMS alert and a decline of stroke code activations, reperfusion treatments, and interhospital transfers, mostly at local centers. Patients suffering an acute stroke during the pandemic period had higher odds of poor functional outcome and death. The complete stroke care system's analysis is crucial to allocate resources appropriately.

Single chemical entities with potential to simultaneously interact with two binding sites are emerging strategies in medicinal chemistry. We have designed, synthesized and functionally characterized the first bitopic ligands for the CB2 receptor. These compounds selectively target CB2 versus CB1 receptors. Their binding mode was studied by molecular dynamic simulations and site-directed mutagenesis.

To identify patients at high risk of fracture using clinical risk factors could reduce health costs arising from the realization of a bone densitometry. The aim of this study was to compare the FRAX score without bone mineral density (BMD) with the criteria proposed by the Argentine Society of Osteoporosis (SAO) to consider starting antiresorptive treatment. We conducted an observational, cross-sectional study where 330 postmenopausal women between 40 and 90 years of age were included. The number of treatments given if the FRAX tool without BMD had been followed was compared with the number of treatments indicated using the SAO criteria. Using the SAO criteria, 85 (25.8%) patients would initiate antiresorptive treatment compared with 15 (4.5%) using the FRAX without BMD (p = 0.0019). Among the 67 patients with a diagnosis of osteoporosis by BMD determination, all of them (100%) would have received treatment by using the SAO criteria compared with 10 (15%) using the FRAX score (p = 0.011). The use of FRAX without BMD significantly underestimates the number of patients who should receive antiresorptive treatment. In patients diagnosed with osteoporosis by BMD, the FRAX score underestimates the number of patients to be treated.

Alternative live feeds for small and sensitive fish early life stages such as pikeperch (Sander lucioperca L., 1758) can improve the larval quantity, quality and performance in aquaculture. Therefore, this study evaluated the cyclopoid copepod Apocyclops panamensis (Marsh, 1913) as live feed for pikeperch larviculture from day 11 post hatch (dph) in two independent experiments. In both experiments, pikeperch larvae had the highest specific growth rate (SGR) when they fed on Brachionus plicatilis until dph 11 and A. panamensis until dph 16-18. SGR was related to a decrease in total fatty acids (FAs), saturated FAs and monounsaturated FAs in pikeperch larvae, indicating their use as energy for growth. Within the polyunsaturated FAs, docosahexaenoic acid (DHA) increased in larvae fed with A. panamensis and coincided with the highest SGR suggesting that DHA is accumulated in larvae as structural FA. Our study demonstrated a suitable pikeperch larval fatty acid composition for growth after feeding A. panamensis compared with Artemia sp. from dph 11 until dph 16 and previously fed with B. plicatilis. Moreover, it highlighted the importance of the dietary PUFAs in pikeperch rearing, specifically of linoleic acid (LA) from dph 4 until dph 11 and of DHA from dph 11 onwards.

Nosemosis is caused by intracellular parasites (Nosema apis and Nosema ceranae) that infect the midgut epithelial cells in adult honey bees. Recent studies relate N. ceranae to Colony Collapse Disorder and there is some suggestion that Nosema spp., especially N. ceranae, induces high mortality in honey bees, a fact that is considered as a serious threat for colony survival. 604 samples of adult honey bees for Nosema spp. analysis were collected from beekeeping colonies across Spain and were analysed using PCR with capillary electrophoresis. We also monitored 77 Andalusian apiaries for 2 years; the sampled hives were standard healthy colonies, without any special disease symptoms. We found 100% presence of Nosema spp. in some locations, indicating that this parasite was widespread throughout the country. The two year monitoring indicated that 87% of the hives with Nosema spp. remained viable, with normal honey production and biological development during this period of time. The results of these trials indicated that both N. ceranae and N. apis could be present in these beehives without causing disease symptom and that there is no evidence for the replacement of N. apis by N. ceranae, supporting the hypothesis that nosemosis is not the main reason of the collapse and death of beehives.

Background/Objective: In child custody disputes, one of the remit of the forensic psychologist is to evaluate parental attributes while suspecting defensiveness. The instrument of choice for undertaking this double task is the MMPI. Method: As to establish the state of the art on this, a meta-analysis was undertaken with a total of 32 primary studies from which 256 effect sizes were assessed. A meta-analysis was undertaken, effect sizes were corrected for sampling error and criterion unreliability. Results: The results revealed a positive, significant, large and generalizable mean true effect size for the L, K, S and MP scales, and the L + K and L + K-F indexes. The Wsd was positive, significant and large, but not generalizable. A negative and significant, but not generalizable mean true effect size was found for the F and generalizable for F-K index. The effect sizes for the L, K, S and MP scales, and the L + K and L + K-F indexes were equal. Both the gender of parents (father vs. mother) and the context of evaluation (parent child custody disputes vs. parenting capacity) were assessed as moderators. Conclusions: The results are discussed in relation to forensic practice.
Antecedentes/Objetivo: En los casos de disputa por la custodia, el psicólogo forense tiene entre sus cometidos la evaluación de las competencias parentales, así como sospechar disimulación. Para esta doble tarea, el instrumento de referencia es el MMPI. Método: Para establecer el estado de la cuestión se llevó a cabo un meta-análisis encontrando 32 estudios primarios de los que se obtuvieron 256 tamaños del efecto. Los tamaños del efecto fueron corregidos por error de muestreo y falta de fiabilidad del criterio. Resultados: Los resultados mostraron un tamaño del efecto medio verdadero positivo, significativo, grande y generalizable para las escalas L, K, S y MP, y los índices L + K y L + K-F. Para Wsd, también resultó positivo, significativo y grande, pero no generalizable. Para F y el índice F-K fue negativo y significativo, pero no generalizable para F y generalizable para F-K. Los tamaños del efecto de las escalas L, K, S y MP, y los índices L + K-F y L + K resultaron ser iguales. Se estudiaron como moderadores el género del progenitor (padre vs. madre) y el contexto de evaluación (progenitores en disputa por la custodia de los hijos vs. evaluación de la capacidad parental). Conclusiones: Se discute la utilidad para la práctica forense de estos resultados.
RESUMEN
Free-living marine nematode communities of the Larsen B embayment at the eastern Antarctic Peninsula were investigated to provide insights on their response and colonization rate after large-scale ice-shelf collapse. This study compares published data on the post-collapse situation from 2007 with new material from 2011, focusing on two locations in the embayment that showed highly divergent communities in 2007 and that are characterized by a difference in timing of ice-shelf breakup. Data from 2007 exposed a more diverse community at outer station B.South, dominated by the genus Microlaimus. On the contrary, station B.West in the inner part of Larsen B was poor in both numbers of individuals and genera, with dominance of a single Halomonhystera species. Re-assessment of the situation in 2011 showed that communities at both stations diverged even more, due to a drastic increase in Halomonhystera at B.West compared to relatively little change at B.South. On a broader geographical scale, it seems that B.South gradually starts resembling other Antarctic shelf communities, although the absence of the genus Sabatieria and the high abundance of Microlaimus still set it apart nine years after the main Larsen B collapse. In contrast, thriving of Halomonhystera at B.West further separates its community from other Antarctic shelf areas.
RESUMEN
AIMS: This study evaluates a possible relationship between reactive oxygen species (ROS) and cyclooxygenase (COX)-2-derived products in conductance and resistance arteries from hypertensive animals. Angiotensin II (Ang II)-infused mice or spontaneously hypertensive rats treated with the NAD(P)H Oxidase inhibitor apocynin, the mitochondrion-targeted SOD2 mimetic Mito-TEMPO, the superoxide dismutase analog tempol, or the COX-2 inhibitor Celecoxib were used. RESULTS: Apocynin, Mito-TEMPO, and Celecoxib treatments prevented Ang II-induced hypertension, the increased vasoconstrictor responses to phenylephrine, and the reduced acetylcholine relaxation. The NOX-2 inhibitor gp91ds-tat, the NOX-1 inhibitor ML171, catalase, and the COX-2 inhibitor NS398 abolished the ex vivo effect of Ang II-enhancing phenylephrine responses. Antioxidant treatments diminished the increased vascular COX-2 expression, prostanoid production, and/or participation of COX-derived contractile prostanoids and thromboxane A(2) receptor (TP) in phenylephrine responses, observed in arteries from hypertensive models. The treatment with the COX-2 inhibitor normalized the increased ROS production (O(2)·(-) and H(2)O(2)), NAD(P)H Oxidase expression (NOX-1, NOX-4, and p22phox) and activity, MnSOD expression, and the participation of ROS in vascular responses in both hypertensive models. Apocynin and Mito-TEMPO also normalized these parameters of oxidative stress. Apocynin, Mito-TEMPO, and Celecoxib improved the diminished nitric oxide (NO) production and the modulation by NO of phenylephrine responses in the Ang II model. INNOVATION: This study provides mechanistic evidence of circuitous relationship between COX-2 products and ROS in hypertension. CONCLUSION: The excess of ROS from NAD(P)H Oxidase and/or mitochondria and the increased vascular COX-2/TP receptor axis act in concert to induce vascular dysfunction and hypertension.

Identificar pacientes con alto riesgo de fractura utilizando factores de riesgo clínicos podría reducir los gastos en salud derivados de la realización de una densitometría ósea. El objetivo de este estudio fue comparar el score de FRAX sin determinación de densidad mineral ósea (DMO) con los criterios propuestos por la Sociedad Argentina de Osteoporosis (SAO), para considerar el inicio de tratamiento antirresortivo. Realizamos un estudio observacional, transversal. Se incluyeron 330 mujeres postmenopáusicas entre 40 y 90 años de edad. Se determinó la cantidad de tratamientos indicados según se utilice la herramienta FRAX sin DMO, o los criterios de la SAO. Utilizando los criterios de la SAO, 85 (25.8%) pacientes recibirían tratamiento, mientras que si se utilizara la herramienta FRAX sin DMO, lo harían 15 (4.5%) pacientes (p = 0.0019). De los 67 pacientes con diagnóstico de osteoporosis por densitometría ósea, todas recibirían tratamiento utilizando los criterios de la SAO y solo 10 (15%) lo harían si utilizáramos el score de FRAX sin DMO (p = 0.011). La utilización del score de FRAX sin DMO reduce en forma significativa la cantidad de pacientes tratables en comparación con los criterios actuales de la SAO. En pacientes con diagnóstico de osteoporosis por DMO, el score de FRAX subestima los pacientes a tratar.
