Womenâs presence and roles in video games journalism: ananalysis of newsrooms and cultural critique in Spanish specialized media
IntroducciĂłn: El periodismo cultural destaca por su funciĂłn prescriptiva, que marca la agenda al determinar cuĂĄles son los productos que merecen recibir la atenciĂłn del pĂșblico. Dentro de esta ĂĄrea informativa se encuentran los videojuegos, una industria tradicionalmente criticada por sus marcadas desigualdades de gĂ©nero. Este artĂculo se propone describir la presencia y el papel de la mujer en los principales medios especializados españoles. MetodologĂa: Se estudiaron la estructura redaccional de los portales 3DJuegos, AnaitGames, AreaJugones, Eurogamer, IGN, HobbyConsolas, Meristation, Nintenderos y Vandal, asĂ como todos los anĂĄlisis de videojuegos publicados entre 1997 y 2022 (n=34.529). Resultados: Las mujeres apenas representan el 18,6% de las plantillas de las grandes revistas del sector, y su vinculaciĂłn a estas se produce sobre todo por medio de la figura del colaborador externo. Su presencia en los puestos de mando es inexistente en siete de las nueve webs escogidas. AdemĂĄs, en los Ășltimos 25 años apenas han firmado un 3,6% de todos los anĂĄlisis publicados, si bien la cifra ha vivido un tĂmido pero constante crecimiento en los Ășltimos tiempos impulsada por los cambios acometidos en AnaitGames, Eurogamer y Meristation. Principalmente suelen escribir sobre videojuegos musicales o aptos para todos los pĂșblicos; los juegos para adultos, violentos o de conducciĂłn se reservan por lo general a hombres. Conclusiones: Este trabajo pone de manifiesto la enorme brecha de gĂ©nero existente aĂșn hoy en la prensa de videojuegos, y llama la atenciĂłn sobre determinados estereotipos que parecen seguir perpetuĂĄndose en la prensa especializada española.Introduction: Cultural journalism is characterized by its prescriptive function, which sets the agenda by determining which products deserve to receive public attention. Within this area of specialization is video games journalism, whose industry has traditionally been criticized for its marked gender inequalities. This article aims to describe the presence and role of women in Spanish specialized media outlets. Methodology: We studied the newsroom composition of the websites 3DJuegos, AnaitGames, AreaJugones, Eurogamer, IGN, HobbyConsolas, Meristation, Nintenderos and Vandal, as well as all their reviews published between 1997 and 2022 (n=34,529). Results: Women barely represent 18.6% of the staff of the major magazines in the sector, and are most frequently linked to them as external collaborators. Their presence in managerial tasks is non-existent in seven of the nine outlets. In addition, in the last 25 years they have only signed 3.6% of all the reviews, although the figure has experienced a timid but constant growth in recent years, driven by the changes made in AnaitGames, Eurogamer and Meristation. They usually write about musical videogames, as well as those suitable for all audiences, while adult, violent or driving games are generally reserved for men. Conclusions: This work highlights the enormous gender gap that still exists today in video games press, and draws the attention to certain stereotypes that continue to perpetuate in Spanish specialized press
An ubiquitous and non intrusive system for pervasive advertising using NFC and geolocation technologies and air hand gestures
In this paper we present a pervasive proposal for advertising using mobile phones, Near Field Communication,
geolocation and air hand gestures. Advertising post built by users in public/private spaces can store multiple ads containing
any kind of textual, graphic or multimedia information. Ads are automatically shows in the mobile phone of the users using
a notification based process considering relative user location between the posts and the user preferences. Moreover, ads can
be stored and retrieved from the post using hand gestures and Near Field Communication technology. Secure management of
information about users, posts, and notifications and the use of instant messaging enable the development of systems to extend
the current advertising strategies based on Web, large displays or digital signage
Palbociclib with Fulvestrant or Letrozole in Endocrine-Sensitive Patients with HR-Positive/HER2-Negative Advanced Breast Cancer: A Detailed Safety Analysis of the Randomized PARSIFAL Trial

Palbociclib has gained a central role in the treatment of hormone receptor-positive (HR+)/human epidermal growth factor receptor 2-negative (HER2â) advanced breast cancer (ABC). Despite its manageable toxicity profile, venous thromboembolism (VTE) or interstitial lung disease (ILD)/pneumonitis may infrequently occur. Therefore, we provide a comprehensive summary of the safety and tolerability of the combination of endocrine therapy and palbociclib among patients included in the randomized phase 2 PARSIFAL study.
Materials and Methods
Patients with endocrine-sensitive HR+/HER2- ABC and no prior therapy in an advanced setting (nâ
=â
486) were randomly assigned 1:1 to receive fulvestrantâpalbociclib (FP) or letrozoleâpalbociclib (LP). Laboratory tests and the incidence of adverse events (AEs) were recorded at baseline and day 1 of each cycle. Progression-free survival (PFS) was estimated for patients with and without VTE.
Results
A total of 483 patients were analyzed. Neutropenia, leukopenia, anemia, asthenia, arthralgia, fatigue, and diarrhea were the most frequent AEs in both groups. Febrile neutropenia occurred in 3 (1.2%) patients of the FP group and in 1 (0.4%) patient in the LP group. Six (2.5%; 0.4% grade 3) patients in the FP group and 6 patients (2.5%; 0.4% grade 3) in the LP group experienced ILD/pneumonitis. Pulmonary embolism was reported in 12 (5.0%) patients in the FP group and 6 (2.5%) patients in the LP group. Advanced age at baseline was the only factor significantly associated with an increased risk of pulmonary embolism (Pâ
<â
.01).
Conclusion
The PARSIFAL data confirmed the favorable safety profile of both palbociclib regimens. VTE and ILD/pneumonitis were occasionally reported, and their early detection allowed patients to continue treatment effectively without detriment to efficacy.The PARSIFAL study was sponsored by Medica Scientia Innovation Research S.L.

Hyperglycaemia is an early and frequent adverse event during alpelisib treatment. METALLICA aimed to evaluate prophylactic metformin to prevent or reduce hyperglycaemia occurrence in patients with HR+/HER2â/PIK3CA-mutated advanced breast cancer (ABC).
Methods
Between August 13th, 2020 and March 23rd, 2022, this 2-cohort, phase 2, multicentre, single-arm trial (NCT04300790) enrolled patients with HR+/HER2â/PIK3CA-mutated ABC: cohort A, normal glycaemia (fasting plasma glucose <100 mg/dL [<5.6 mmol/L] and HbA1c <5.7%), and cohort B, prediabetes (fasting plasma glucose 100â140 mg/dL [5.6â7.8 mmol/L] and/or haemoglobin A1C [HbA1c] 5.7â6.4%). Participants were at least 18 years old, with Eastern Cooperative Oncology Group performance status of 0â1, and up to two prior lines of endocrine therapy (ET) for ABC. Alpelisib plus ET were administered in 28-day cycles after initiation of prophylactic metformin plus ET. Primary endpoint was the incidence of grade 3â4 hyperglycaemia over the first 8 weeks. Secondary endpoints included safety, progression-free survival (PFS), objective response rate (ORR), and clinical benefit rate (CBR). The primary objective for cohort A and B is met with â€7 (14.6%) and â€4 (20%) patients with grade 3â4 hyperglycaemia over the first 8 weeks, respectively.
Findings
233 patients were screened, and 68 (20.2%) patients were enrolled in cohorts A (n = 48) and B (n = 20). Median follow-up was 7.8 months (IQR 1.4â19.6). Over the first 8 weeks, one (2.1%) of 48 patients in cohort A (95% CI: 0.5â11.1; P < 0.0001), and three (15.0%) of 20 patients in cohort B (95% CI: 5.6â37.8; P = 0.016) had grade 3â4 hyperglycaemia. Serious treatment-related adverse events occurred in seven patients (10.3%). The most common were rash (two [2.9%]), vomiting (two [2.9%]), and diarrhoea (two [2.9%]). Discontinuation of alpelisib caused by AEs was reported in nine patients (13.2%), none caused by hyperglycaemia. At data cutoff (15 June, 2022), no treatment-related deaths were observed. In the full analysis set, median PFS was 7.3 months (95% CI: 5.9ânot reached), ORR was 20.6% (95% CI: 11.7â32.1%), and CBR was 52.9% (95% CI: 40.4â65.2).
Interpretation
In HR+/HER2â/PIK3CA-mutated ABC, prophylactic metformin before alpelisib plus endocrine treatment has low incidence and severity of alpelicib-induced hyperglycaemia.Novartis Pharmaceuticals
Palbociclib Rechallenge for Hormone Receptor-Positive/HER-Negative Advanced Breast Cancer: Findings from the Phase II BioPER Trial
Hormone receptor; Advanced breast cancerCà ncer de mama avançat; Receptor hormonalCåncer de mama avanzado; Receptor hormonalPurpose:
To assess the efficacy and exploratory biomarkers of continuing palbociclib plus endocrine therapy (ET) beyond progression on prior palbociclib-based regimen in patients with hormone receptorâpositive/HER2-negative (HR+/HER2â) advanced breast cancer (ABC).
Patients and Methods:
The multicenter, open-label, phase II BioPER trial included women who had experienced a progressive disease (PD) after having achieved clinical benefit on the immediately prior palbociclib plus ET regimen. Palbociclib (125 mg, 100 mg, or 75 mg daily orally for 3 weeks and 1 week off as per prior palbociclib-based regimen) plus ET of physician's choice were administered in 4-week cycles until PD or unacceptable toxicity. Coprimary endpoints were clinical benefit rate (CBR) and percentage of tumors with baseline loss of retinoblastoma (Rb) protein expression. Additional endpoints included safety and biomarker analysis.
Results:
Among 33 patients enrolled, CBR was 34.4% [95% confidence interval (CI), 18.6â53.2; P < 0.001] and 13.0% of tumors (95% CI, 5.2â27.5) showed loss of Rb protein expression, meeting both coprimary endpoints. Median progression-free survival was 2.6 months (95% CI, 1.8â6.7). No new safety signals were reported. A signature that included baseline mediators of therapeutic resistance to palbociclib and ET (low Rb score, high cyclin E1 score, ESR1 mutation) was independently associated with shorter median progression-free survival (HR, 22.0; 95% CI, 1.71â282.9; P = 0.018).
Conclusions:
Maintaining palbociclib after progression on prior palbociclib-based regimen seems to be a reasonable, investigational approach for selected patients. A composite biomarker signature predicts a subset of patients who may not derive a greater benefit from palbociclib rechallenge, warranting further validation in larger randomized controlled trials.This work was supported by Pfizer.

Altered Expression of CD300a Inhibitory Receptor on CD4+ T Cells From Human Immunodeficiency Virus-1-Infected Patients: Association With Disease Progression Markers
The ability of the CD300a inhibitory receptor to modulate immune cell functions and its involvement in the pathogenesis of many diseases has aroused a great interest in this molecule. Within human CD4+ T lymphocytes from healthy donors, the inhibitory receptor CD300a is differentially expressed among different T helper subsets. However, there are no data about the expression and regulation of CD300a receptor on CD4+ T cells from human immunodeficiency virus (HIV)-1-infected patients. The objective of this study was to investigate the expression of CD300a on CD4+ T cells from HIV-infected patients on suppressive combined antiretroviral therapy (cART) and cART naĂŻve patients. Our results have demonstrated that the expression levels of this inhibitory receptor were higher on CD4+ T cells from HIV-1 infected subjects compared with healthy donors, and that cART did not reverse the altered expression of CD300a receptor in these patients. We have observed an increase of CD300a expression on both PD1+CD4+ and CD38+CD4+ T cells from HIV-1 infected people. Interestingly, a triple positive (CD300a+PD1+CD38+) subset was expanded in naĂŻve HIV-1 infected patients, while it was very rare in healthy donors and patients on cART. Finally, we found a negative correlation of CD300a expression on CD4+ T lymphocytes and some markers associated with HIV-1 disease progression. Thus, our results show that HIV-1 infection has an impact in the regulation of CD300a inhibitory receptor expression levels, and further studies will shed light into the role of this cell surface receptor in the pathogenesis of HIV infection
Real-world data of fulvestrant as first-line treatment of postmenopausal women with estrogen receptor-positive metastatic breast cancer
Goals of endocrine therapy for advanced breast cancer (ABC) include prolonging survival rates, maintaining the quality of life, and delaying the initiation of chemotherapy. We evaluated the effectiveness of fulvestrant as first-line in patients with estrogen receptor (ER)-positive ABC with relapse during or after adjuvant anti-estrogenic therapy in real-world settings. Retrospective, observational study involving 171 postmenopausal women with ER-positive ABC who received fulvestrant as first-line between January 2011 and May 2018 in Spanish hospitals. With a median follow-up of 31.4 months, the progression-free survival (PFS) with fulvestrant was 14.6 months. No differences were seen in the visceral metastatic (14.3 months) versus non-visceral (14.6 months) metastatic subgroup for PFS. Overall response rate and clinical benefit rate were 35.2% and 82.8%. Overall survival was 43.1 months. The duration of the clinical benefit was 19.2 months. Patients with ECOG performance status 0 at the start of treatment showed a significant greater clinical benefit rate and overall survival than with ECOG 1-2. Results in real-world settings are in concordance with randomized clinical trials. Fulvestrant continues to demonstrate clinical benefits in real-world settings and appears be well tolerated as first-line for the treatment of postmenopausal women with ER-positive ABC
Loss of FBXW7 and accumulation of MCL1 and PLK1 promote paclitaxel resistance in breast cancer
FBXW7 is a component of SCF (complex of SKP1, CUL1 and F-box-protein)-type ubiquitin ligases that targets several oncoproteins for ubiquitination and degradation by the proteasome. FBXW7 regulates cellular apoptosis by targeting MCL1 for ubiquitination. Recently, we identified PLK1 as a new substrate of FBXW7 modulating the intra-S-phase DNA-damage checkpoint. Taxanes are frequently used in breast cancer treatments, but the acquisition of resistance makes these treatments ineffective. We investigated the role of FBXW7 and their substrates MCL1 and PLK1 in regulating the apoptotic response to paclitaxel treatment in breast cancer cells and their expression in breast cancer tissues. Paclitaxel-sensitive MDA-MB-468 and a paclitaxel-resistant MDA-MB-468R subclone were used to study the role of FBXW7 and substrates in paclitaxel-induced apoptosis. Forced expression of FBXW7 or downregulation of MCL1 or PLK1 restored sensitivity to paclitaxel in MDA-MB-468R cells. By contrary, FBXW7-silenced MDA-MB-468 cells became resistant to paclitaxel. The expression of FBXW7 and substrates were studied in 296 invasive carcinomas by immunohistochemistry and disease-free survival was analyzed in a subset of patients treated with paclitaxel. In breast cancer tissues, loss of FBXW7 correlated with adverse prognosis markers and loss of FBXW7 and MCL1 or PLK1 accumulation were associated with diminished disease-free survival in paclitaxel-treated patients. We conclude that FBXW7 regulates the response to paclitaxel by targeting MCL1 and PLK1 in breast cancer cells and thus targeting these substrates may be a valuable adjunct for paclitaxel treatment. Also, FBXW7, MCL1 and PLK1 may be relevant predictive markers of tumor progression and response to paclitaxel treatment.España, Ministerio de EconomĂa y Competitividad SAF2014- 53799-C2-1/2-REspaña, ConsejerĂa de Salud AI-0025-2015España, ConsejerĂa de InnovaciĂłn Ciencia y Empresa P10- CTS-624
Clinical validation of the EndoPredict test in node-positive, chemotherapy-treated ER+/HER2â breast cancer patients: results from the GEICAM 9906 trial
INTRODUCTION: EndoPredict (EP) is an RNA-based multigene test that predicts the likelihood of distant recurrence in patients with estrogen receptor-positive (ER+), human epidermal growth factor receptor 2ânegative (HER2â) breast cancer (BC) who are being treated with adjuvant endocrine therapy. Herein we report the prospective-retrospective clinical validation of EP in the node-positive, chemotherapy-treated, ER+/HER2â BC patients in the GEICAM 9906 trial. METHODS: The patients (N = 1,246) were treated either with six cycles of fluorouracil, epirubicin and cyclophosphamide (FEC) or with four cycles of FEC followed by eight weekly courses of paclitaxel (FEC-P), as well as with endocrine therapy if they had hormone receptorâpositive disease. The patients were assigned to EP risk categories (low or high) according to prespecified cutoff levels. The primary endpoint in the clinical validation of EP was distant metastasis-free survival (MFS). Metastasis rates were estimated using the Kaplan-Meier method, and multivariate analysis was performed using Cox regression. RESULTS: The molecular EP score and the combined molecular and clinical EPclin score were successfully determined in 555 ER+/HER2â tumors from the 800 available samples in the GEICAM 9906 trial. On the basis of the EP, 25% of patients (n = 141) were classified as low risk. MFS was 93% in the low-risk group and 70% in the high-risk group (absolute risk reduction = 23%, hazard ratio (HR) = 4.8, 95% confidence interval (CI) = 2.5 to 9.5; P < 0.0001). Multivariate analysis showed that, in this ER+/HER2â cohort, EP results are an independent prognostic parameter after adjustment for age, grade, lymph node status, tumor size, treatment arm, ER and progesterone receptor (PR) status and proliferation index (Ki67). Using the predefined EPclin score, 13% of patients (n = 74) were assigned to the low-risk group, who had excellent outcomes and no distant recurrence events (absolute risk reduction vs high-risk group = 28%; P < 0.0001). Furthermore, EP was prognostic in premenopausal patients (HR = 6.7, 95% CI = 2.4 to 18.3; P = 0.0002) and postmenopausal patients (HR = 3.3, 95% CI = 1.3 to 8.5; P = 0.0109). There were no statistically significant differences in MFS between treatment arms (FEC vs FEC-P) in either the high- or low-risk groups. The interaction test results between the chemotherapy arm and the EP score were not significant. CONCLUSIONS: EP is an independent prognostic parameter in node-positive, ER+/HER2â BC patients treated with adjuvant chemotherapy followed by hormone therapy. EP did not predict a greater efficacy of FEC-P compared to FEC alone
