Las mujeres subversivas de Sonia Rivera-Valdés1
2007
Gloria Anzaldúa, prematuramente fallecida en la primavera de 2004, dice en Borderlands/La Frontera: The New Mestiza, remodelando una conocida cita de Virginia Woolf donde la británica reivindica que \"como mujer, [su] patria es el mundo entero\": Como mestiza, no tengo patria, mi nación me expuM; sin embargo, pertenezco a cualquier país porque soy la hermana o h amante potencial de todas las mujeres. También nos habla Martirio de su gusto por los juguetes sexuales, otro gran tabú que ha generado múltiples controversias en el ámbito de los estudios gays y lesbianos;-' o de su promiscuidad sexual, que le ha llevado a tener, según ella misma confiesa, \"cientos de relaciones\" de las que no se avergüenza.

The Canary Islands inhabitants, a recently admixed population with significant North African genetic influence, has the highest incidence of childhood-onset type 1 diabetes (T1D) in Spain and one of the highest in Europe.
HLA
accounts for half of the genetic risk of T1D.
Aims
To characterize the classical
HLA-DRB1
and
HLA-DQB1
alleles in children from Gran Canaria with and without T1D.
Methods
We analyzed classic
HLA-DRB1
and
HLA-DQB1
alleles in childhood-onset T1D patients (
n
= 309) and control children without T1D (
n
= 222) from the island of Gran Canaria. We also analyzed the presence or absence of aspartic acid at position 57 in the
HLA-DQB1
gene and arginine at position 52 in the
HLA-DQA1
gene. Genotyping of classical
HLA-DQB1
and
HLA-DRB1
alleles was performed at two-digit resolution using Luminex technology. The chi-square test (or Fisher's exact test) and odds ratio (OR) were computed to assess differences in allele and genotype frequencies between patients and controls. Logistic regression analysis was also used.
Results
Mean age at diagnosis of T1D was 7.4 ± 3.6 years (46% female). Mean age of the controls was 7.6 ± 1.1 years (55% female).

) exhibited significant differences. A total of 58% of the studied
HLA-DQB1
genes in our control population lacked aspartic acid at position 57.
Conclusions
In this population, the overall distributions of the
HLA-DRB1
and
HLA-DQB1
alleles are similar to those in other European populations. However, the frequency of the non-Asp-57
HLA-DQB1
molecules is greater than that in other populations with a lower incidence of T1D. Based on genetic, historical and epidemiological data, we propose that a common genetic background might help explain the elevated pediatric T1D incidence in the Canary Islands, North-Africa and middle eastern countries.

ObjectiveDesign a risk model to predict bacteraemia in patients attended in emergency departments (ED) for an episode of infection.MethodsThis was a national, prospective, multicentre, observational cohort study of blood cultures (BC) collected from adult patients (≥ 18 years) attended in 71 Spanish EDs from October 1 2019 to March 31, 2020. Variables with a p value < 0.05 were introduced in the univariate analysis together with those of clinical significance. The final selection of variables for the scoring scale was made by logistic regression with selection by introduction. The results obtained were internally validated by dividing the sample in a derivation and a validation cohort.ResultsA total of 4,439 infectious episodes were included. Of these, 899 (20.25%) were considered as true bacteraemia. A predictive model for bacteraemia was defined with seven variables according to the Bacteraemia Prediction Model of the INFURG-SEMES group (MPB-INFURG-SEMES). The model achieved an area under the curve-receiver operating curve of 0.924 (CI 95%:0.914–0.934) in the derivation cohort, and 0.926 (CI 95%: 0.910–0.942) in the validation cohort. Patients were then split into ten risk categories, and had the following rates of risk: 0.2%(0 points), 0.4%(1 point), 0.9%(2 points), 1.8%(3 points), 4.7%(4 points), 19.1% (5 points), 39.1% (6 points), 56.8% (7 points), 71.1% (8 points), 82.7% (9 points) and 90.1% (10 points). Findings were similar in the validation cohort. The cut-off point of five points provided the best precision with a sensitivity of 95.94%, specificity of 76.28%, positive predictive value of 53.63% and negative predictive value of 98.50%.ConclusionThe MPB-INFURG-SEMES model may be useful for the stratification of risk of bacteraemia in adult patients with infection in EDs, together with clinical judgement and other variables independent of the process and the patient.

Abstract
Improvements in breast cancer survival rate have been achieved through a variety of multimodal therapeutic approaches, which play a key role in the patients’ healthcare pathway and their Patient-Reported Outcomes (PROs) from a Value-Based Healthcare (VBHC) perspective. This paper analyses differences in PROs of patients diagnosed with breast cancer according to their healthcare pathway. A cohort of 690 patients diagnosed with breast cancer between 2018 and 2020 at six European sites was used. PROs were assessed at baseline and 6 months using the International Consortium for Health Outcome Measures standard set. Archetypes defined by patient characteristics and treatment trajectories served as the basis for comparison. Multivariate linear regression models were used to analyse differences in PROs across archetypes. Functional scores generally worsened over 6 months, particularly in physical functioning, whereas emotional functioning improved. Archetypes undergoing mastectomy, with or without reconstruction, showed significant decreases in body image perception and satisfaction with breasts. Pain, fatigue, and peripheral symptoms were prevalent in most archetypes, with those receiving chemotherapy reporting the greatest symptom burden. Patients with in situ carcinoma and patients undergoing conservative surgery plus radiotherapy showed minimal deterioration. The use of PROs in a real-world setting enables the identification of differences across patient archetypes based on their therapeutic pathways. This information provides valuable insights for refining patient-centred care guiding VBHC strategies in oncology, developing of personalized care solutions, and facilitating Shared-Decision Making.

IntroductionSuicide is one of the leading public health issues worldwide. Mobile health can help us to combat suicide through monitoring and treatment. The SmartCrisis V.2.0 randomised clinical trial aims to evaluate the effectiveness of a smartphone-based Ecological Momentary Intervention to prevent suicidal thoughts and behaviour.Methods and analysisThe SmartCrisis V.2.0 study is a randomised clinical trial with two parallel groups, conducted among patients with a history of suicidal behaviour treated at five sites in France and Spain. The intervention group will be monitored using Ecological Momentary Assessment (EMA) and will receive an Ecological Momentary Intervention called ‘SmartSafe’ in addition to their treatment as usual (TAU). TAU will consist of mental health follow-up of the patient (scheduled appointments with a psychiatrist) in an outpatient Suicide Prevention programme, with predetermined clinical appointments according to the Brief Intervention Contact recommendations (1, 2, 4, 7 and 11 weeks and 4, 6, 9 and 12 months). The control group would receive TAU and be monitored using EMA.Ethics and disseminationThis study has been approved by the Ethics Committee of the University Hospital Fundación Jiménez Díaz. It is expected that, in the near future, our mobile health intervention and monitoring system can be implemented in routine clinical practice. Results will be disseminated through peer-reviewed journals and psychiatric congresses. Reference number EC005-21_FJD. Participants gave informed consent to participate in the study before taking part.Trial registration numberNCT04775160.

(1) Background: The liver-first approach may be indicated for colorectal cancer patients with synchronous liver metastases to whom preoperative chemotherapy opens a potential window in which liver resection may be undertaken. This study aims to present the data of feasibility and short-term outcomes in the liver-first approach. (2) Methods: A prospective observational study was performed in Spanish hospitals that had a medium/high-volume of HPB surgeries from 1 June 2019 to 31 August 2020. (3) Results: In total, 40 hospitals participated, including a total of 2288 hepatectomies, 1350 for colorectal liver metastases, 150 of them (11.1%) using the liver-first approach, 63 (42.0%) in hospitals performing <50 hepatectomies/year. The proportion of patients as ASA III was significantly higher in centers performing ≥50 hepatectomies/year (difference: 18.9%; p = 0.0213). In 81.1% of the cases, the primary tumor was in the rectum or sigmoid colon. In total, 40% of the patients underwent major hepatectomies. The surgical approach was open surgery in 87 (58.0%) patients. Resection margins were R0 in 78.5% of the patients. In total, 40 (26.7%) patients had complications after the liver resection and 36 (27.3%) had complications after the primary resection. One-hundred and thirty-two (89.3%) patients completed the therapeutic regime. (4) Conclusions: There were no differences in the surgical outcomes between the centers performing <50 and ≥50 hepatectomies/year. Further analysis evaluating factors associated with clinical outcomes and determining the best candidates for this approach will be subsequently conducted.

Stroke is the leading cause of disability and the second cause of death worldwide. The increasing burden of stroke underscores the importance of optimising rehabilitation protocols. Virtual reality (VR) can improve poststroke prognosis. A VR software combining gamification, full immersion and stroke specificity (ie, the Development and validation of a novel viRtual rEality software for improving diSability and quality of lifE in patients with sTroke (RESET) software) might substantially improve disability and quality of life (QoL). However, this technology is still very scarce. The RESET trial aims to assess the effects of an early 10-week gamified, fully immersive and stroke-specific VR intervention (ie, starting at week 3 poststroke) on disability and QoL in people with stroke in the subacute phase. People with ischaemic or haemorrhagic stroke (n=94) aged ≥18 years will be randomised to receive (1) usual care (UC), (2) commercial VR or (3) gamified, fully immersive and stroke-specific VR (RESET). The three groups will receive UC (ie, three sessions/week of 90 min of standard rehabilitation). The VR groups will additionally receive three VR sessions of 20 min per week. The outcome measures will be assessed at baseline (week 2 from stroke occurrence), week 13 (approximately 90 days from the event) and week 26 (approximately 6 months from the event). The primary outcome is disability measured with the Barthel Index. Secondary outcomes include QoL, upper-extremity and lower-extremity motor function, gross manual dexterity, handgrip strength and cognitive function. This study will unravel the effects of a gamified, fully immersive and stroke-specific VR software on disability and QoL in patients with stroke in the early subacute phase.NCT06132399.

Disentangling the value equation: a step forward in value-based healthcare
2024
Background
The value equation of value-based healthcare (VBHC) as a single figure remains ambiguous, closer to a theoretical framework than a useful tool for decision making. The challenge lies in the way patient-centred outcomes (PCOs) might be combined to produce a single value of the numerator. This paper aims to estimate the weights of PCOs to provide a single figure in the numerator, which ultimately will allow a VBHC figure to be reached.
Methods
A cohort of patients diagnosed with breast cancer (n = 690) with a 6-month follow-up recruited in 2019–20 across six European hospitals was used. Patient-reported outcomes (PROs), clinical-related outcomes (CROs), and clinical and socio-demographic variables were collected. The numerator was defined as a composite indicator of the PCOs (CI-PCO), and regression analysis was applied to estimate their weights and consequently arrive at a single figure.
Results
Pain showed as the highest weight followed by physical functioning, emotional functioning, and ability to work, and then by a symptom, either arm or breast. PCOs weights were robust to sensitivity analysis. The CI-PCO value was found to be more informative than the health-related quality of life (HRQoL) value.
Conclusions
To the best of our knowledge, this is the first research to combine the PCOs proposed by ICHOM to provide a single figure in the numerator of the value equation. This figure shows a step forward in VBHC to reach a holistic benchmarking across healthcare centres and a value-based payment. This research might also be applied in other medical conditions as a methodological pathway.

Background Data from the sentinel surveillance system of severe acute respiratory infections in Spain were used to estimate the impact of administration of nirsevimab to children born from 1 April 2023 onwards. Methods Estimated RSV hospitalisations in < 1‐year‐olds during weeks 40, 2023, to 8, 2024, were compared to the number that would be expected after accounting for the background change in RSV circulation in the 2023/24 season, compared to 2022/23. Results We estimated 9364–9875 RSV hospitalisations less than expected, corresponding to a 74%–75% reduction.
