Objectives/Goals: This project will enrich our understanding of basal breast carcinogenesis, highlighting the distinct biological differences in breast cancer risk between non-Hispanic Black (NHB) or non-Hispanic White (NHW) women, but also has the potential to provide real-world solutions thereby contributing to reducing health disparities in breast cancer outcomes Methods/Study Population: In the biological investigation, I am utilizing a unique cohort of normal breast tissues from Mayo Clinic patients who underwent breast reduction surgery that have self-identified as NHB or NHW premenopausal women. From these tissues, we are able to subculture human mammary epithelial cells, which we will use for our consequent experiments. For the qualitative study, I aim to recruit up to 40–50 eligible NHB women identified at increased risk for breast cancer and conduct semi-structured qualitative interviews informed by the National Institute on Minority Health and Health Disparities Research Framework. Results/Anticipated Results: Gene expression profiling on our cohort of 15 NHB and 40 NHW premenopausal women identified a gene expression signature in NHB women indicative of elevated Hedgehog signaling, a key factor in triple-negative breast cancer (TNBC) development and progression. I hypothesize that persistent activation of Hedgehog signaling within NHB women instigates the proliferation and transformation of basal stem cells within the breast, thus fueling TNBC development. Understanding the perceptions and experiences of NHB women that are identified as being at an increased risk for BC will aid in the identification of barriers and facilitators to their risk reduction care and in turn provide implementation strategies that could contribute to alleviating the racial disparity seen in TNBC morbidity, mortality, and preventative care. Discussion/Significance of Impact: The significance of this project lies in its dual approach, uncovering basal breast cancer mechanisms in a high-risk group using normal breast tissue and evaluating the perspectives from NHB women to enhance the practical relevance of our findings.
Considering the demographic shift towards an ageing population, the financial threats that arise after retirement and the ongoing debates about extending working life, it is crucial to thoroughly understand the impact of retirement on the health of older individuals. This article presents a systematic review conducted according to the standards established by PRISMA statement CINAHL and APA PsycArticles databases by EBSCOhost, Pubmed, Scopus and Web of Science, for longitudinal studies published between 2013 and 2023. The aim of the review was to synthesise evidence of the effects of retirement on health, for example physical functioning, morbidity or mortality. From 1,757 records, 19 papers were included. Twelve longitudinal studies consistently linked retirement to declining physical function, increased disease prevalence and higher all-cause mortality risk. The evidence did not show a clear conclusion on biomarkers as health outcomes. The article identifies five explanatory mechanisms behind the retirement–health relationship: working conditions, retirement types, financial security, lifestyle changes and social participation. Retirement can have some adverse effects on health; however, the health consequences of withdrawal are likely to vary by pre-retirement factors. These findings carry implications for the current debate of extending working life and the social security system for older people.
Different agencies have emphasized the need to evaluate current serological methods for screening patients with suspected urogenital schistosomiasis. However, there is still a lack of evidence regarding the most appropriate methods for this purpose. Here we assessed the diagnostic efficacy of a newly developed serological technique that utilizes the recombinant protein Sh-TSP-2, applied to the urine and serum of migrants suspected of having urogenital schistosomiasis. The sensitivity, specificity, positive and negative predictive values of an in-house enzyme-linked immunosorbent assay (ELISA) using the recombinant protein Sh-TSP-2 were analysed and compared with other commercial serological methods. Due to the limitations of microscopy as a perfect reference method, a latent class analysis (LCA) and composite reference standard (CRS) approach was used to determine the sensitivity and specificity of each test. According to the LCA model, the commercial tests NovaLisa® and immunochromatography test (ICT) immunoglobulin G–immunoglobulin M (IgG–IgM) presented the highest sensitivity (100%), whereas the Sh-TSP-2 serum ELISA test had 79.2%. The Sh-TSP-2 urine and serum ELISA tests had the highest specificities among the serological methods (87.5 and 75%, respectively). CRS modelling showed that the ICT IgG–IgM, NovaLisa® and Sh-TSP-2 serum tests led in sensitivity at 97.1, 88.6 and 71.4%, respectively, with all tests except that the ICT IgG–IgM test having a specificity >90%. Sh-TSP-2 has been validated as a screening tool for patients suspected of having urogenital schistosomiasis. Although commercial serological tests have shown higher sensitivities, Sh-TSP-2 could be valuable for confirming results from tests with lower specificity. Nevertheless, further studies with larger patient cohorts are necessary to fully verify its potential.
The rise of populist parties in Europe has generated an enormous amount of academic literature. Previous research has thoroughly examined the factors contributing to the electoral success of populist parties. Surprisingly, very little attention has been paid to the role of decentralization, one of the most widespread forms of governance in the world. This paper aims to fill this gap by presenting a theoretical and empirical account of the effect of decentralization on the electoral fortunes of populist parties in Europe. Using aggregated data from election results in 30 European countries, this paper puts competing hypotheses to the test. I argue that the mechanism linking decentralization and populist parties’ national election results is, in fact, indirect and depends on the existence of a regional tier of government. Results suggest that having representation in subnational parliaments plays a significant role in the national success of populist parties, and this effect is contingent on the degree of regional authority.
An important question in dynamical systems is the classification problem, that is, the ability to distinguish between two isomorphic systems. In this work, we study the topological factors between a family of multidimensional substitutive subshifts generated by morphisms with uniform support. We prove that it is decidable to check whether two minimal aperiodic substitutive subshifts are isomorphic. The strategy followed in this work consists of giving a complete description of the factor maps between these subshifts. Then, we deduce some interesting consequences on coalescence, automorphism groups, and the number of aperiodic symbolic factors of substitutive subshifts. We also prove other combinatorial results on these substitutions, such as the decidability of defining a subshift, the computability of the constant of recognizability, and the conjugacy between substitutions with different supports.
Soil-transmitted helminth (STH) infections afflict people worldwide, especially in tropical and subtropical regions. Strongyloides stercoralis is distinctive from other STH nematodes by its complex life cycle features of autoinfection, parthenogenesis, and environmental reproduction. This scoping review aims to identify the structures, features, and techniques employed in existing STH models, emphasizing their potential application in describing S. stercoralis infection dynamics. A comprehensive search was conducted in the Medline, Embase, and Scopus databases for studies published until 14 June 2024. A total of 47 studies presenting a new model or novel adaptation of an existing model to human STH infection transmission were identified: only one described S. stercoralis transmission in humans. The identified models were predominantly deterministic and focused on the dynamics of mean worm load within hosts and the infectiousness of the environmental reservoir. One model addressed transmission in multi-host scenarios, as not all STH transmission cycles involve multiple hosts. Models were frequently used to simulate the effectiveness of mass drug administration, including drug efficacy and treatment coverage, while water, sanitation, and hygiene (WASH), health education, and vaccination were less explored. Given the limitation of individual-level data, compartmental models may be a reasonable starting point for S. stercoralis transmission. For a comprehensive understanding, incorporating parasite life cycle features into the model, exploring multi-host dynamics, including a diverse range of host heterogeneities, and assessing the impact of climatic factors like rainfall and land surface temperature on parasite survival in the environment may be beneficial, especially in settings where their importance is notable.
This study provides a holistic approach to the potential drivers of corporate environmental policy. Institutional and/or stakeholder theories are used to explain any influence on this type of policy in situations with different characteristics. Specifically, the analysis considers country-, industry-, and firm-level determinants of an international sample of listed companies. Exploratory factor analysis was first applied to the variables at the country level because their underlying interrelationships were unknown. Using ordered probit models clustered at the firm level, we found that some environmental characteristics of a country and some macro-level variables considered together affect corporate environmental policy, along with pressure from industry peers. Moreover, we observed that companies with better policies for stakeholders, greater board independence, and greater gender diversity tended to develop better environmental policies. This study offers insight into fostering environmental responsibility through policy incentives and effective corporate governance structures.
We numerically study the influence of a soluble surfactant on the microjetting mode of the liquid–liquid flow focusing configuration. The surfactant adsorbs on the interface next to the feeding capillary and accumulates in front of the emitted jet, significantly lowering the surface tension there. The resulting Marangoni stress substantially alters the balance of the tangential stresses at the interface but does not modify the interface velocity. The global stability analysis at the minimum flow rate stability limit shows that the Marangoni stress collaborates with soluto-capillarity to stabilize the microjetting mode. Our analysis unveils the noticeable effect of the Marangoni stress associated with the surface tension perturbation. Surfactant diffusion and desorption hardly affect the stability limit. Transient numerical simulations show how subcritical and supercritical base flows respond to a spatially localized initial perturbation. Our parametric study indicates that the minimum flow rate ratio depends on the adsorption constant and the surfactant concentration through the product of these two variables. The surfactant stabilizing effect increases with the outer stream flow rate. We show that surfactants not only stabilize the microemulsion resulting from the jet breakup in hydrodynamic focusing, but also allow for the reduction of droplet size. Our findings advance the fundamental understanding of the complex role of surfactants in tip streaming via hydrodynamic focusing. In particular, our results contradict the common assumption that adding surfactant favours tip streaming simply because it reduces the meniscus tip surface tension.
The harmful consumption of alcohol is known for how tortuous its management can be in mental health, encouraging introspection of it as a serious problem is perhaps the main key to starting to battle against its damaging influence on the development of a functional and full life.
Objectives
To describe a clinical case showing an unpredictible complication in an alcohol detoxification process.
Methods
54-year-old man, native of Cádiz, widowed for half a decade, without children. He resides with his parents in the family home. Currently unemployed for approximately a year. He has previously worked in the IT sector. As a notable somatic history, we found long-established arterial hypertension and a total hip replacement. He has been under irregular follow-up with a mental health team for anxiety-depressive symptoms in the context of grief. He goes to the emergency service brought by his family to begin the detoxification process in the hospital setting. He acknowledges ethanol consumption since he was widowed, which began when he awakes; quantities that ranged between one or up to three bottles of distilled liquor per day, generally consumption is in the home environment. A little less than a year ago, he began to isolate himself in his room and abandon his self-care, eating increasingly insufficient food intake, refusing to receive professional care to quit the habit, mainly because he did not recognize it as disruptive.
The patient was admitted to hospital with symptoms suggestive of withdrawal, making it extremely difficult to control blood pressure levels. On the third day of admission to the acute care unit, fever peaks, blood pressure levels well below normal parameters, and compromised level of consciousness began to be evident.
Results
Blood tests were performed that, together with the clinical picture, suggested imminent septic shock, so critical care was contacted for transfer and stabilization. A germ of probable urinary etiology sensitive to a broad spectrum of antibiotics was isolated in blood cultures, and the medication of the detoxification process was progressively optimized. Once clinical stability was achieved at all levels, an inpatient cessation resource was managed, which the patient accepted and considered suitable for his complete recovery.
Conclusions
A holistic approach to the alcoholic patient is important, since serious problems of an organic nature often arise. This is why a multidisciplinary intervention is necessary, as well as a holistic approach to care, involving both classic pharmacology and assiduous long-term psychotherapeutic intervention.
A 28 year old patient will be presented. This paramilitary man was brought to the Emergency Room due to an autolytic attempt with Benzodiazepines, along with a mouth suture, in the context of a soon to be resolved problematic ankle osteosynthesis procedure. The patient claimed to be suffering pain, furthermore struggling due to the fact he could not be working due to his ankle issue. Language barrier was a problem during the interview.
Objectives
The objetives of this case is to try to explain the issues that may arise in patients with personality disorders in the context of an autolytic attempt
Methods
This patient will be presented, along with systematic bibliography review of the topic.
Results
The following results were extracted upon the attention given to this patient which was admitted to the Psychiatric Unit.
First of all, the mouth stitches were removed, along with a petition for toxicological analysis. The results gave positive for cannabis and benzodiazepines. The patient was also brought previously this year with another autolytic attempt, this time on cocaine consumption too. Furthermore, a thorough review was made of the other autolytic attempts, including those which happened in his country of origin. The patient has hundreds of small cuts among his arms, from previews cuts made in the past. Furthermore, subcutaneous wounds were auto inflicted in the ER, with a small blade.
Among the whole interview, it was clear he had a personality disorder, with high impulsivity levels and lack of control once the situation overflows.
We also tried to understand the outcome of suturing his mouth. The patient referred his acts of impulsiveness due to his overwhelming situation of both having no job at this moment and the pain he was suffering due to his ankle procedure.
The patient was admitted to our Unit due to the high risk he could repeat this act. Upon arrival, the same day he was admitted, the patient asked if he had to stay at the unit. When explaining the following already told event, furthermore insisting in the possibility of been evaluated by the Traumatology team, he proceeded to try and hang himself with his medical-hospital clothing.
The patient was treated with antipsychotics. Along with Lormetazepam at night. At the end of the hospitalization, and after been evaluated by the Psychiatrist of this Unit, the patient was also treated with Lithium due to its effectiveness in the treatment of autolytic attempts.
Conclusions
Personality disorders are one of the psychiatric pathologies that prevail with greater frequency in autolytic attempts 1. Additionally, it should be taken into account the possible ongoing consumption of psychoactive drugs that could also derive in psychopathological decompensation. On top of the following, the use of antipsychotic treatment is indicated for the managing of conduction altercations 2, besides Lithium being a great option in managing suicidal temptations 3.
Clozapine is an atypical antipsychotic synthesised in 1958. It was withdrawn from the market in the 1970s due to the appearance of agranulocytosis, but was reintroduced due to strong evidence of its efficacy and superiority over other antipsychotics in treatment-resistant schizophrenia.
Objectives
To describe the adequate response to clozapine in treatment-refractory psychosis.
Methods
Review of the scientific literature based on a relevant clinical case.
Results
A 16-year-old woman was admitted to a psychiatric inpatient unit for psychotic symptoms and behavioural disorders. She lives with her father and older sister; she has not been in contact with her mother, who lives in another country, for several years. She attends secondary school, with poor academic performance. Maternal diagnosis of schizophrenia. She started using cannabis two years ago, with a progressive increase up to 20 grams per week. He reports the onset of a feeling of strangeness a year ago, with progressive isolation in his room, referring to delirious ideation of harm towards classmates and people from his town, self-referentiality and delirious interpretations of religious mystical content (“God speaks to me through a dove”). He comments on the phenomenon of theft and thought-reading. Soliloquies and unmotivated laughter are observed.
Conclusions
Treatment was started with risperidone, progressively increasing the dose up to optimisation, without achieving a decrease in positive symptoms, but with the appearance of excessive sedation and sialorrhoea. It was combined with aripiprazole up to 20mg, maintained for a couple of weeks, without significant clinical improvement. Given the failure of two lines of therapy, it was decided to change to clozapine up to a dose of 75mg, with adequate tolerance and response, achieving a distancing of the delirious ideation. Regular haematological controls were performed, with no alterations in haemogram or troponins.
Ethnicity and migration have an impact on illness models and consequently how, when and where people seek and obtain care. Early Intervention Psychosis (EIP) teams attend high rates of migrant and ethnic diverse populations but the study of ethnic differences in pathways to obtain and maintain care is still scarce . The most consistent findings are that minorities are less involved with primary services, have a higher risk of being treated in a coercive way and are at higher risk of early disengagement. Despite the increasing migration rates there has been very little investigation in Spain.
Objectives
To investigate ethno-racial differences in pathways to obtain care, adherence and engagement during their first year of follow-up of subjects who start treatment at EIP of Reus, Catalonia, Spain
Methods
Participants
This is an observational 12 months follow-up retrospective study including all consecutively subjects with First Episode of Psychosis (FEP) referred to the EIP from January 2015 to January 2019. Visible ethno-racial status was self-reported being grouped as belonging to minority ethno-racial group if they were coded “any other than White regardless of country of origin”. ‘White’ was the majority group
Study variables:
At program entry:
Source of referral
At 12- months:
Adherence to the service:
Admissions to in-patient unit
Disengagement
Results
184 FEP subjects (mean age 22.8 years and 66.1% of males) were included. Nearly 31% belonged to a minority ethno-racial group being the Maghrebi (60.4%) followed by the Latin-American (20.1%) the most frequent minority groups. The 81.2% of the minority group were first-generation migrants and 7.5% second generation migrants. The 52.2 % were referred from community services, 18.5% from emergency unit and 29.3% from inpatient unit. At follow up 64.5%, were highly adherent to EIP (> 75% of attended appointments), 16.7% required hospitalization and 11% disengaged. Multivariate analysis showed that the minority group was 2.19 times more likely to be low adherent [(95% CI 0.78-3.17; p=0.03], 2.89 times more likely to be hospitalised [(95% CI 1.20-6.98); p=0.01], and 4 times more likely to disengage from the EIP [(95% CI 1.35-11.90); p= 0.01] during follow-up than the majority group. No group differences were found in pathways to obtain care or in causes of disengagement.
Conclusions
In agreement with previous studies from other countries we found high rates of ethno-racial diversity in the EIP of Reus. In addition, we also found inequalities in the use of services, being minorities more likely to disengage, to be low adherent to the program and at greater risk of hospitalization. On contrary to other studies we did not find significant differences between groups in the source of referral to EIP
In recent years, there has been an increase in the prevalence of illicit use of fentanyl and other opioids in the United States population. This has led to an increase in medical, psychopathological and abuse-associated comorbidity, an increase in deaths and a decrease in the age of consumption, and has become a serious emerging problem in young people.
We present the case of an 18-year-old woman from the United States who recently settled in Spain and started a follow-up in Mental Health due to opioid and other substance abuse problems.
Objectives
To address the growing problem surrounding the illicit use of fentanyl and opioids as drugs of abuse based on the presentation of the clinical case mentioned above.
Methods
Bibliographic search and description of a clinical case of a patient under follow-up by Mental Health at the “Hospital Clínico Universitario de Valladolid”.
Results
An 18-year-old woman from the United States who has been living with her father in Spain since the summer of 2023, having moved to Spain due to problems related to substance abuse.
With no previous medical or surgical history and with a history of follow-up in Mental Health in her country of origin for depressive symptomatology, dysfunctional personality traits and abuse of different toxic substances since adolescence.
After a brief and erratic follow-up in Psychiatry for anxious-depressive symptoms reactive to a complex and conflictive relationship with his mother and marked academic difficulties during the first years of adolescence, at the age of 15 he started using cannabis and alcohol, thus beginning a period marked by relationships with marginalized sectors of the population, substance abuse and school failure.
As his cannabis consumption intensified, he began to consume fentanyl prescribed to his mother, as well as other opioids to which he had access illegally, for which reason he had to be admitted twice to detoxification centers without results, which is why his family finally decided to move him to Spain.
Conclusions
In recent years, fentanyl abuse has become a serious public health problem that is mainly centered in the young population.
High levels of impulsivity and lack of frustration tolerance predispose to the use of illicit substances for elusive purposes.
Substance abuse carries with it not only an important organic comorbidity, but also a marked socio-familial and economic repercussion.
It is widely described in the scientific literature that patients who suffer from some type of congenital syndrome such as Di George Syndrome are more likely to present some type of psychopathological alteration during their development that may require intervention and treatment by infant and juvenile mental health teams in coordination with neuropediatrics (1). On this occasion, we will present the clinical case of a patient who regularly attends psychiatry consultations for management of anxious symptoms with impulse control deficits associated with intellectual disability, diagnosed since childhood with tetralogy of Fallot and later with Di George syndrome. In this type of case, treatment is usually considered taking into account possible comorbidities at the organic level (since there may be cardiological involvement, which can be an added difficulty when taking into account the adverse effects of some psychotropic drugs) (2).
Objectives
This is followed by the presentation of the clinical case, which can serve to exemplify this type of case and clarify any doubts that may arise regarding treatment.
Methods
Presentation of the clinical case and review of updated scientific literature on the subject.
Results
Patient who first came to the infantile-junior consultations at the age of 8 years due to delay in the acquisition of verbal language and impulsivity. The patient had a history of pediatric follow-up since birth for different physical symptoms that finally led to the diagnosis of Di George syndrome.
Given the difficulties he presented both at home and at school, different psychometric tests were performed and it was determined that it could be beneficial to initiate treatment with extended-release methylphenidate. Prior to treatment, psychomotor restlessness (without aggressiveness) and difficulty in concentration prevailed, which improved significantly after upward adjustment of the dose to a guideline corresponding to his age and weight. It was not necessary in this case to administer other treatments (the possibility of starting Aripiprazole in case of episodes of agitation was considered, but it was not necessary). The patient has continued to be monitored by cardiology to assess the possible side effects of the treatment (since it can increase heart rate and blood pressure (3), but so far no complications have been detected).
Thanks to psychotherapeutic and educational intervention, language acquisition was achieved, although to date he still requires support due to the difficulties he still presents.
Conclusions
It is important to take into account the possible side effects of psychopharmacological treatment in patients with an associated congenital syndrome. Intensive and comprehensive follow-up by psychiatry and pediatrics (and later by their primary care physician) should be performed.
Parental Reflective Functioning (PRF) refers to parents’ ability to view their children’s and their own behavior by considering internal mental states, such as thoughts, desires, and intentions. Depression has been described as compromising reflective functioning in female samples, whereas other studies have not detected differences in RF between depressed and non-depressed mothers.
Objectives
We aim to study whether a group intervention focused on postpartum depression, which we have already observed to cause significant changes in the mother-child bond and the severity of depressive, also improves parental reflective functioning.
Significant changes were observed in the Pre-Mentalization Modes (pre=2.37±.457, post=2.03±.520, t=2.0206, p=0.027) and Certainty About Mental States (pre=2.87±1.141, post=3.68±.908, t=-2.814, p=0.010) subscales of the PRFQ, with no significant changes in the Interest and Curiosity subscale (t=-.516, p=0.309). A significant correlation was also observed between pre-post change in EPDS scores and pre-post change in the Certainty About Mental States subscale of the PRFQ (r=-.640, p<.05), while no significant correlations were observed with the rest of the PRFQ subscales, nor with the PBQ.
Conclusions
A brief cognitive-behavioral group therapy developed specifically to treat postpartum depression improves pre-post scores on the Pre-Mentalization (lower post- than pre- score) and Certainty About Mental States (higher post- than pre- score) subscales of the PRFQ. Although a control group is needed to determine the actual effect of the intervention, as time could also play a role in the observed changes, this is an encouraging result. Moreover, the improvement obtained in Certainty About Mental States is inversely correlated with the pre-post changes observed in the EPDS, meaning that the greater the improvement in depression, the greater the improvement in the aforementioned subscale of the PRFQ. A larger sample is needed to assess a hypothetical mediating effect of depression in the observed change.
How do international crises unfold? We conceptualize international relations as a strategic chess game between adversaries and develop a systematic way to measure pieces, moves, and gambits accurately and consistently over a hundred years of history. We introduce a new ontology and dataset of international events called ICBe based on a very high-quality corpus of narratives from the International Crisis Behavior (ICB) Project. We demonstrate that ICBe has higher coverage, recall, and precision than existing state of the art datasets and conduct two detailed case studies of the Cuban Missile Crisis (1962) and the Crimea-Donbas Crisis (2014). We further introduce two new event visualizations (event iconography and crisis maps), an automated benchmark for measuring event recall using natural language processing (synthetic narratives), and an ontology reconstruction task for objectively measuring event precision. We make the data, supplementary appendix, replication material, and visualizations of every historical episode available at a companion website crisisevents.org.
We propose expanding the authors’ shared novelty-seeking basis for creativity and curiosity by emphasizing an underlying computational principle: Minimizing prediction errors (mismatch between predictions and incoming data). Curiosity is tied to the anticipation of minimizing prediction errors through future, novel information, whereas creative AHA moments are connected to the actual minimization of prediction errors through current, novel information.
In this chapter, we examine the evolving definition of sex tourism. Through a comprehensive literature review focusing on Latin America and the Caribbean, we assess the long history of commodified sex and travel and the difficulties in defining the practice as exclusive to heterosexual men purchasing sex or as a phenomenon exclusive to the Global South. A case study of Havana, Cuba, contributes to a deeper understanding of how colonial cities benefitted from commodified sex connected to travellers and racialized bodies. In analyzing the scholarship on sex tourism, we appreciate the heterogeneity of arrangements, identities, ambiguity, and fluidity of relationships. Both hosts and guests are looking for opportunities to enhance their lives and to challenge the gender, sexual, and racial dictates of their society. Tourist-related intimacies, therefore, are used for personal and familial gains and mobility in the global political economy. The findings reveal that while some studies have adopted narrow definitions, a more comprehensive approach argues for understanding sex tourism as part of a spectrum of intimate encounters that combine sex and money, encompassing everything from marriage to sex work.
