Sequencing of Kaposi's Sarcoma Herpesvirus (KSHV) genomes from persons of diverse ethnicities and provenances with KSHV-associated diseases demonstrate multiple infections, novel polymorphisms, and low intra-host variance.

Recently published near full-length KSHV genomes from a Cameroon Kaposi sarcoma case-control study showed strong evidence of viral recombination and mixed infections, but no sequence variations associated with disease. Using the same methodology, an additional 102 KSHV genomes from 76 individuals with KSHV-associated diseases have been sequenced. Diagnoses comprise all KSHV-associated diseases (KAD): Kaposi sarcoma (KS), primary effusion lymphoma (PEL), KSHV-associated large cell lymphoma (KSHV-LCL), a type of multicentric Castleman disease (KSHV-MCD), and KSHV inflammatory cytokine syndrome (KICS). Participants originated from 22 different countries, providing the opportunity to obtain new near full-length sequences of a wide diversity of KSHV genomes. These include near full-length sequence of genomes with KSHV K1 subtypes A, B, C, and F as well as subtype E, for which no full sequence was previously available. High levels of recombination were observed. Fourteen individuals (18%) showed evidence of infection with multiple KSHV variants (from two to four unique genomes). Twenty-six comparisons of sequences, obtained from various sampling sites including PBMC, tissue biopsies, oral fluids, and effusions in the same participants, identified near complete genome conservation between different biological compartments. Polymorphisms were identified in coding and non-coding regions, including indels in the K3 and K15 genes and sequence inversions here reported for the first time. One such polymorphism in KSHV ORF46, specific to the KSHV K1 subtype E2, encoded a mutation in the leucine loop extension of the uracil DNA glycosylase that results in alteration of biochemical functions of this protein. This confirms that KSHV sequence variations can have functional consequences warranting further investigation. This study represents the largest and most diverse analysis of KSHV genome sequences to date among individuals with KAD and provides important new information on global KSHV genomics.

Implementing a pilot study of COVID-19 self-testing in high-risk populations and remote locations: results and lessons learnt.

BACKGROUND: Rapid antigen-detection tests for SARS-CoV-2 self-testing represent a useful tool for pandemic control and expanding access to community-level case screening. COVID-19 self-tests have been extensively used in high-income countries since 2021; however, their introduction and programmatic implementation in low- and middle-income countries was delayed. We aimed to identify and continuously improve a weekly COVID-19 self-testing model among staff at healthcare facilities and schools. METHODS: This mixed-methods, observational prospective study was conducted in 5 healthcare centres and 24 schools in Georgia, between June and December 2022. The study comprised the integration of COVID-19 self-testing into the national mandatory testing programme for high-risk groups, with primary distribution of self-tests among staff performed weekly, plus secondary distribution to their household members. These use cases were selected because NCDC was seeking to strengthen their already strong weekly testing programme, by investigating self-testing to ease the burden of testing in the healthcare system. Online surveys and semi-structured interviews were used for data collection. RESULTS: In total, 2156 participants were enrolled (1963 female, 72%). At baseline and mid- and end-points, 88%, 97% and 99%, respectively, of participants agreed/strongly agreed they would self-test. Similarly, the majority were willing to report their self-testing results (88%, 98% and 96% at baseline and mid- and end-points, respectively). Weekly reporting of test results to the national COVID-19 database was high during all the implementation. There were 622 COVID-19 positive results reported, and linked to care, from 601 individuals (282 participants and 319 household members). Findings from qualitative interviews showed great satisfaction with self-testing for its convenience, ease of use, trust in the results, no need to travel for diagnostics, and increased perception of safety. CONCLUSIONS: Our findings contribute to the evidence-base regarding self-testing strategies conducted via workplaces and secondary distribution to households. Willingness to perform a COVID-19 self-test increased after implementation. This pilot enhanced pandemic preparedness through expansion of the national self-testing reporting system, development of communications materials, changes in the national legal framework and coordination mechanisms, and improved perceptions around self-care in the community. The lessons learnt can inform operational aspects of the introduction and scale-up of self-care strategies.

mTORC1-dependent AMD1 regulation sustains polyamine metabolism in prostate cancer.

Activation of the PTEN-PI3K-mTORC1 pathway consolidates metabolic programs that sustain cancer cell growth and proliferation. Here we show that mechanistic target of rapamycin complex 1 (mTORC1) regulates polyamine dynamics, a metabolic route that is essential for oncogenicity. By using integrative metabolomics in a mouse model and human biopsies of prostate cancer, we identify alterations in tumours affecting the production of decarboxylated S-adenosylmethionine (dcSAM) and polyamine synthesis. Mechanistically, this metabolic rewiring stems from mTORC1-dependent regulation of S-adenosylmethionine decarboxylase 1 (AMD1) stability. This novel molecular regulation is validated in mouse and human cancer specimens. AMD1 is upregulated in human prostate cancer with activated mTORC1. Conversely, samples from a clinical trial with the mTORC1 inhibitor everolimus exhibit a predominant decrease in AMD1 immunoreactivity that is associated with a decrease in proliferation, in line with the requirement of dcSAM production for oncogenicity. These findings provide fundamental information about the complex regulatory landscape controlled by mTORC1 to integrate and translate growth signals into an oncogenic metabolic program.

Inhibition of Prolyl Oligopeptidase Restores Prohibitin 2 Levels in Psychosis Models: Relationship to Cognitive Deficits in Schizophrenia.

Cognitive impairment represents one of the core features of schizophrenia. Prolyl Oligopeptidase (POP) inhibition is an emerging strategy for compensating cognitive deficits in hypoglutamatergic states such as schizophrenia, although little is known about how POP inhibitors exert their pharmacological activity. The mitochondrial and nuclear protein Prohibitin 2 (PHB2) could be dysregulated in schizophrenia. However, altered PHB2 levels in schizophrenia linked to N-methyl-D-aspartate receptor (NMDAR) activity and cognitive deficits are still unknown. To shed light on this, we measured the PHB2 levels by immunoblot in a postmortem dorsolateral prefrontal cortex (DLPFC) of schizophrenia subjects, in the frontal pole of mice treated with the NMDAR antagonists phencyclidine and dizocilpine, and in rat cortical astrocytes and neurons treated with dizocilpine. Mice and cells were treated in combination with the POP inhibitor IPR19. The PHB2 levels were also analyzed by immunocytochemistry in rat neurons. The PHB2 levels increased in DLPFC in cases of chronic schizophrenia and were associated with cognitive impairments. NMDAR antagonists increased PHB2 levels in the frontal pole of mice and in rat astrocytes and neurons. High levels of PHB2 were found in the nucleus and cytoplasm of neurons upon NMDAR inhibition. IPR19 restored PHB2 levels in the acute NMDAR inhibition. These results show that IPR19 restores the upregulation of PHB2 in an acute NMDAR hypoactivity stage suggesting that the modulation of PHB2 could compensate NMDAR-dependent cognitive impairments in schizophrenia.

Synthetic Lethality by Co-Inhibition of Androgen Receptor and Polyadenosine Diphosphate-Ribose in Metastatic Prostate Cancer.

Androgen receptor pathway inhibitors (ARPI) and polyadenosine diphosphate-ribose inhibitors (PARPi) are part of the standard of care in patients with metastatic castration-resistant prostate cancer (mCRPC). There is biological evidence that the association of ARPI and PARPi could have a synergistic effect; therefore, several ongoing clinical trials are investigating the efficacy of this combination with preliminary results that are not perfectly concordant in identifying patients who can obtain the most benefit from this therapeutic option. The purpose of this review is to describe the PARPi mechanisms of action and to analyze the biological mechanisms behind the interplay between the androgen receptor and the PARPi system to better understand the rationale of the ARPI + PARPi combinations. Furthermore, we will summarize the preliminary results of the ongoing studies on these combinations, trying to understand in which patients to apply. Finally, we will discuss the clinical implications of this combination and its possible future perspectives.

Who has to act? A qualitative exploration of emerging adults' critical consciousness during the COVID-19 pandemic.

The COVID-19 pandemic and violence against people of Color during 2020 brought troubling racial inequities to the forefront of American discourse. In line with the Critical Consciousness (CC) and Social Justice Youth Development (SJYD) frameworks, emerging adults may have developed their capacity for critical reflection, motivation, and action against systemic inequities. We drew from interviews with 27 emerging adults (ages 18-23) across the US, and used thematic analysis to explore differences in their reflections, motivations to act, and actions based on their racial/ethnic identification. We found nuanced variability in their critical reflections based on self, social, or global awareness and experiences of marginalization. White and Asian emerging adults used vague language or expressed feeling their reflections were insufficient. Black and Latinx emerging adults emphasized the importance of education and raising awareness. Although all emerging adults took action based on a sense of duty, few engaged in critical action; decisions to take in-person action varied based on whether they viewed racism or COVID-19 as a greater threat. Findings demonstrate that emerging adults' experiences of racialization may have related to their CC development. We share implications for community psychologists conducting antiracist research addressing White fragility and dismantling racial hierarchy.

[Prevalence of mental symptoms in the Sahrawi refugees in Tindouf camps, Algeria, determined using the Goldberg General Health Questionnaire 28]. / Prevalencia de síntomas mentales entre los refugiados saharauis en Tinduf, Argelia, utilizando el Cuestionario de Salud General Goldberg 28.

OBJECTIVE: To assess the prevalence of psychopathological symptoms among Saharawi refugees and the influence of sociodemographic factors on the phenotypic expression of mental disorders. DESIGN: Cross-sectional descriptive study. LOCATION: Primary and hospital health care. PARTICIPANTS: 383 participants over 18 years of age, 59.8% women and 40.2% men, with a mean age of 37.2 (SD = 13.0), from the Laayoune camp, and from the Rabuni National Hospital. METHODOLOGY: A descriptive, cross-sectional and analytical study was carried out between January and August 2017. Participants were selected by consecutive sampling. The main variable was the presence of mental symptoms, measured with the Goldberg General Health Questionnaire - 28. A descriptive analysis of each sociodemographic variable (age, sex, educational level, occupation) and its association with the main variable was carried out using Logistic regression. RESULTS: 43.3%, 95%CI (38.4-48.3) obtained a score that suggests the presence of mental symptoms. Women presented a mean score higher than men, in subscales A (somatic symptoms) and in subscale B (anxiety). Age over 50 years and having no educational level were associated with a higher probability of having mental symptoms. CONCLUSIONS: The study shows that the prevalence of mental symptoms among Saharawi refugees is high, and reinforces the need for more scientific research in the field of mental health to put the prevention of mental disorders and the promotion of mental health in the focus of health policy.

Systematic analysis of Kaposi's sarcoma (KS)-associated herpesvirus genomes from a KS case-control study in Cameroon: Evidence of dual infections but no association between viral sequence variation and KS risk.

In sub-Saharan Africa, Kaposi's sarcoma-associated herpesvirus (KSHV) is endemic, and Kaposi's sarcoma (KS) is a significant public health problem. Until recently, KSHV genotype analysis was performed using variable gene regions, representing a small fraction of the genome, and thus the contribution of sequence variation to viral transmission or pathogenesis are understudied. We performed near full-length KSHV genome sequence analysis on samples from 43 individuals selected from a large Cameroonian KS case-control study. KSHV genomes were obtained from 21 KS patients and 22 control participants. Phylogenetic analysis of the K1 region indicated the majority of sequences were A5 or B1 subtypes and all three K15 alleles were represented. Unique polymorphisms in the KSHV genome were observed including large gene deletions. We found evidence of multiple distinct KSHV genotypes in three individuals. Additionally, our analyses indicate that recombination is prevalent suggesting that multiple KSHV infections may not be uncommon overall. Most importantly, a detailed analysis of KSHV genomes from KS patients and control participants did not find a correlation between viral sequence variations and disease. Our study is the first to systematically compare near full-length KSHV genome sequences between KS cases and controls in the same endemic region to identify possible sequence variations associated with disease risk.

Talazoparib, a Poly(ADP-ribose) Polymerase Inhibitor, for Metastatic Castration-resistant Prostate Cancer and DNA Damage Response Alterations: TALAPRO-1 Safety Analyses.

BACKGROUND: The phase II TALAPRO-1 study (NCT03148795) demonstrated durable antitumor activity in men with heavily pretreated metastatic castration-resistant prostate cancer (mCRPC). Here, we detail the safety profile of talazoparib. PATIENTS AND METHODS: Men received talazoparib 1 mg/day (moderate renal impairment 0.75 mg/day) orally until radiographic progression, unacceptable toxicity, investigator decision, consent withdrawal, or death. Adverse events (AEs) were evaluated: incidence, severity, timing, duration, potential overlap of selected AEs, dose modifications/discontinuations due to AEs, and new clinically significant changes in laboratory values and vital signs. RESULTS: In the safety population (N = 127; median age 69.0 years), 95.3% (121/127) experienced all-cause treatment-emergent adverse events (TEAEs). Most common were anemia (48.8% [62/127]), nausea (33.1% [42/127]), decreased appetite (28.3% [36/127]), and asthenia (23.6% [30/127]). Nonhematologic TEAEs were generally grades 1 and 2. No grade 5 TEAEs or deaths were treatment-related. Hematologic TEAEs typically occurred during the first 4-5 months of treatment. The median duration of grade 3-4 anemia, neutropenia, and thrombocytopenia was limited to 7-12 days. No grade 4 events of anemia or neutropenia occurred. Neither BRCA status nor alteration origin significantly impacted the safety profile. The median (range) treatment duration was 6.1 (0.4-24.9) months; treatment duration did not impact the incidence of anemia. Only 3 of the 15 (11.8% [15/127]) permanent treatment discontinuations were due to hematologic TEAEs (thrombocytopenia 1.6% [2/127]; leukopenia 0.8% [1/127]). CONCLUSION: Common TEAEs associated with talazoparib could be managed through dose modifications/supportive care. Demonstrated efficacy and a manageable safety profile support continued evaluation of talazoparib in mCRPC. CLINICALTRIALS.GOV IDENTIFIER: NCT03148795.

Implications of DNA damage repair alterations for the management of prostate cancer.

PURPOSE OF REVIEW: In this review, we summarize the prevalence of alterations in DNA damage repair (DDR) genes in prostate cancer, their clinical significance, the therapeutic strategies developed to take advantage of the impaired tumour ability to repair DNA and the diagnostic approaches available to identify patients likely to benefit from DDR-targeting agents. RECENT FINDINGS: DDR alterations are more frequent in metastatic than in localized prostate cancer and some of them associate with aggressive disease whereas the significance of others remain unclear. The most appropriate management approach for DDR-defective prostate cancer patients is unknown. Clinical trials have demonstrated the efficacy of different poly-ADP ribose polymerase inhibitors (PARPi) to treat metastatic castration-resistant prostate cancer patients with BRCA1/2 alterations, although there may be other DDR alterations that sensitize patients to these drugs. Multiple strategies to target DDR defects are being investigated, including PARPi in combination, platinum-based chemotherapy and immunotherapy, both in earlier and late disease stages. Optimization of molecular testing is paramount for the implementation of precision oncology in prostate cancer. SUMMARY: Certain DDR defects present in prostate cancer have prognostic and therapeutic implications whereas the significance of other DDR alterations is yet to be elucidated.

Evidence for altered host genetic factors in KSHV infection and KSHV-related disease development.

Kaposi's sarcoma-associated herpesvirus (KSHV) is the etiological agent of Kaposi's sarcoma (KS), the most common AIDS-related malignancy. It also causes other rare, but certainly underreported, KSHV-associated pathologies, namely primary effusion lymphoma, multicentric Castleman disease and KSHV inflammatory cytokine syndrome. Epidemiology and pathogenicity studies point to the potential for host genetic predisposition to KSHV infection and/or the subsequent development of KSHV-associated pathologies partly explaining the peculiar geographic and population-specific incidence of KSHV and associated pathologies and discrepancies in KSHV exposure and infection and KSHV infection and disease development. This review consolidates the current knowledge of host genetic factors involved in the KSHV-driven pathogenesis. Studies reviewed here indicate a plausible connection between KSHV susceptibility and host genetic factors that affect either viral access to host cells via entry mechanisms or host innate immunity to viral infection. Subsequent to infection, KSHV-associated pathogenesis, reviewed here primarily in the context of KS, is likely influenced by an orchestrated concert of innate immune system interactions, downstream inflammatory pathways and oncogenic mechanisms. The association studies reviewed here point to interesting candidate genes that may prove important in achieving a more nuanced understanding of the pathogenesis and therapeutic targeting of KSHV and associated diseases. Recent studies on host genetic factors suggest numerous candidate genes strongly associated with KSHV infection or subsequent disease development, particularly innate immune system mediators. Taken together, these contribute toward our understanding of the geographic prevalence and population susceptibility to KSHV and KSHV-associated diseases.

Examining the Sociopolitical Development of Immigrant-Origin Youth During a Season of Social Unrest.

The sociopolitical context for immigrant-origin (I-O) youth's civic development in the U.S. has dramatically shifted in the years following the 2016 election (e.g., heightened xenophobia). I-O children comprise 26% of young people in the U.S. and include those born outside the U.S. (first generation) and those with at least one parent born outside the U.S. (second generation). Using a qualitative approach, this study examined how I-O youth (N = 65, M = 16.22 years) experienced and engaged with the phenomena of the 2020 election season amidst recent economic, political, and social consequences from the pandemic and the current social movements against systemic racism. Findings expand our understanding of how I-O youth engage as political actors by examining the processes surrounding their sociopolitical development.

Capsaicin 8% Dermal Patch for Neuropathic Pain in a Pain Unit.

AIMS: Pain units manage approximately 20% of the patients with neuropathic pain, usually presenting with severe uncontrolled pain associated with substantial impairment of quality-of-life and disability. We aimed to analyze the experience with the capsaicin 8% dermal patch for managing patients with neuropathic pain in a pain unit. DESIGN: This was a post-authorization observational and retrospective study conducted at a single pain unit on patients with peripheral neuropathic pain under routine clinical care. METHODS: Diagnosis of neuropathic pain was based on the Douleur Neuropathique 4 (DN4) questionnaire. Evaluations included pain intensity according to a visual analog scale and the quality-of-life as evaluated with the European Quality of Life-5 Dimensions (EQ-5D). RESULTS: We included 66 patients with neuropathic pain lasting for a median of 24 months. The most frequent diagnosis was iatrogenic neuropathic pain (47%) and two thirds of patients exhibited extreme pain or discomfort. Pain intensity was reduced significantly from a mean (standard deviation [SD]) of 7.20 (1.95) at baseline to 6.02 (2.77) at month 3, leading to a mean change from baseline of 1.19 (95% confidence interval [CI], 0.59 to 1.78; p < .001; Cohen's d 0.49). The extent of the pain area was also significantly reduced from a median (interquartile range [IQR]) of 169.5 cm2 (69.3-299.9) at baseline to 121.2 cm2 (35.4-183.9) at month 3 (p < .001). There was an improvement in most dimensions of quality-of-life, especially regarding "usual activities," "pain/discomfort," and "anxiety/depression." Tolerability was consistent with the known profile. CONCLUSIONS: Our results suggest that the capsaicin 8% dermal patch is a useful and well-tolerated treatment option for managing peripheral neuropathic pain in pain units.

Effectiveness of a game-based educational strategy e-EDUCAGUIA for implementing antimicrobial clinical practice guidelines in family medicine residents in Spain: a randomized clinical trial by cluster.

BACKGROUND: Clinical practice guidelines (CPGs) have teaching potential for health professionals in training clinical reasoning and decision-making, although their use is limited. The objective was to evaluate the effectiveness of a game-based educational strategy e-EDUCAGUIA using simulated clinical scenarios to implement an antimicrobial therapy GPC compared to the usual dissemination strategies to improve the knowledge and skills on decision-making of family medicine residents. Additionally, adherence to e-EDUCAGUIA strategy was assessed. METHODS: A multicentre pragmatic cluster-randomized clinical trial was conducted involving seven Teaching Units (TUs) of family medicine in Spain. TUs were randomly allocated to implement an antimicrobial therapy guideline with e-EDUCAGUIA strategy ( intervention) or passive dissemination of the guideline (control). The primary outcome was the differences in means between groups in the score test evaluated knowledge and skills on decision-making at 1 month post intervention. Analysis was made by intention-to-treat and per-protocol analysis. Secondary outcomes were the differences in mean change intrasubject (from the baseline to the 1-month) in the test score, and educational game adherence and usability. Factors associated were analysed using general linear models. Standard errors were constructed using robust methods. RESULTS: Two hundred two family medicine residents participated (104 intervention group vs 98 control group). 100 medicine residents performed the post-test at 1 month (45 intervention group vs 55 control group), The between-group difference for the mean test score at 1 month was 11 ( 8.67 to 13.32) and between change intrasubject was 11,9 ( 95% CI 5,9 to 17,9). The effect sizes were 0.88 and 0.75 respectively. In multivariate analysis, for each additional evidence-based medicine training hour there was an increase of 0.28 points (95% CI 0.15-0.42) in primary outcome and in the change intrasubject each year of increase in age was associated with an improvement of 0.37 points and being a woman was associated with a 6.10-point reduction. 48 of the 104 subjects in the intervention group (46.2%, 95% CI: 36.5-55.8%) used the games during the month of the study. Only a greater number of evidence-based medicine training hours was associated with greater adherence to the educational game ( OR 1.11; CI 95% 1.02-1.21). CONCLUSIONS: The game-based educational strategy e-EDUCAGUIA shows positive effects on the knowledge and skills on decision making about antimicrobial therapy for clinical decision-making in family medicin residents in the short term, but the dropout was high and results should be interpreted with caution. Adherence to educational games in the absence of specific incentives is moderate. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT02210442 . Registered 6 August 2014.

"Everyone collaborated and came together": The civic promise (and pitfalls) of yPAR for immigrant-origin students in an era of deportation.

OBJECTIVES: In recent years, increased anti-immigrant hostility has trickled into school settings creating toxic climates for immigrant-origin (I-O) students (Rogers, School and society in the age of trump, 2019, UCLA's Institute for Democracy, Education, and Access). Through youth participatory action research (yPAR), this study qualitatively examined how a class of Emerging Bilingual (EB) students aimed to promote more inclusive learning environments by designing, implementing, and evaluating a school-wide program. Here, we consider how the students experienced growth in their civic development as well as how they contended with resistances encountered during the project. METHODS: The current study took place at a majority I-O, northeastern high school and was led by an EB class (n = 20) and its teacher. Participants were as follows: on average 16.5 years; 60% female; and 65% Latinx, 30% Black, and 5% mixed-race (Black-Latino). Multiple data sources documenting the students' experiences were collected (including weekly student reflections and ethnographic field notes) and then thematically analyzed using open coding. RESULTS: Participating students demonstrated civic development as evidenced through: growing confidence that the program could generate positive change; enhanced sense of connection toward their classmates; and increased commitment to future civic engagement. Nonetheless, some participants demonstrated initial trepidation in both disclosing their migration stories as well as the potential efficacy of engaging in the project. Furthermore, others were disappointed by the disinterest displayed by some of their peers and teachers. CONCLUSIONS: Collaborative research can support I-O youths' civic development, though, the resistances encountered and engendered illuminate possible challenges to ensure its benefits.

Health-related quality of life in caregivers of community-dwelling individuals with disabilities or chronic conditions. A gender-differentiated analysis in a cross-sectional study.

BACKGROUND: Most care for people with chronic or disabling conditions living in the community is provided in the family context, and this care is traditionally provided by women. Providing informal care has a negative impact on caregivers' quality of life, which adds to existing health inequalities associated with gender. The aim of this study was to analyze factors associated with the health-related quality of life of caregivers and to determine their differences in a gender-differentiated analysis. METHODS: An observational, cross-sectional, multicenter study was conducted in primary healthcare. A total of 218 caregivers aged 65 years or older were included, all of whom assumed the primary responsibility for caring for people with disabling conditions for at least 6 months per year and agreed to participate in the CuidaCare study. The dependent variable was health-related quality of life, assessed with the EQ-5D. The explanatory variables tested were grouped into sociodemographic variables, subjective burden, caregiving role, social support and variables related to the dependent person. The associations between these variables and health-related quality of life were estimated by fitting robust linear regression models. Separate analyses were conducted for women and men. RESULTS: A total of 72.8% of the sample were women, and 27.2% were men. The mean score on the EQ-5D for female caregivers was 0.64 (0.31); for male caregivers, it was 0.79 (0.23). There were differences by gender in the frequency of reported problems in the dimensions of pain/comfort and anxiety/depression. The variables that were associated with quality of life also differed. Having a positive depression screening was negatively associated with quality of life for both genders: -0.31 points (95% CI: -0.47; -0.15) for female caregivers and -0.48 points (95% CI: -0.92; -0.03) for male caregivers. Perceived burden was associated with quality of life in the adjusted model for women (-0.12 points; 95% CI: -0.19; -0.06), and domestic help was associated in the adjusted model for male caregivers (-0.12 points; 95% CI: -0.19; -0.05). CONCLUSIONS: Gender differences are present in informal caregiving. The impact of providing informal care is different for male and female caregivers, and so are the factors that affect their perceived quality of life. It could be useful it incorporates a gender perspective in the design of nursing support interventions for caregivers to individualize care and improve the quality of life of caregivers.

Associations between critical consciousness and well-being in a national sample of college students during the COVID-19 pandemic.

Critical consciousness (CC) may promote well-being, particularly during the COVID-19 pandemic. In a national survey of 707 college students conducted in April 2020, we first validated the Short Critical Consciousness Scale (ShoCCS) among youth groups not often specifically examined in CC measurement (i.e., Asian, immigrant-origin, LGBQ+, and women youth). Next, we examined associations between ShoCCS subscales and validated measures of both anxiety (Generalized Anxiety Disorder-7) and hopefulness (The Individual-Differences Measure in Hopefulness). The ShoCCS achieved measurement invariance across racial/ethnic groups and immigrant-origin status, and partial invariance among LGBQ+ and women-identifying youth. We found critical reflection and action associated with anxiety for the full sample, but no evidence of moderation by sociodemographic factors. ShoCCS subscales were differentially associated with hopefulness for Asian youth and LGBQ+ youth. This study contributes to the evolution of CC measurement and extends the field by identifying well-being associations during the onset of the COVID-19 pandemic.

Talazoparib monotherapy in metastatic castration-resistant prostate cancer with DNA repair alterations (TALAPRO-1): an open-label, phase 2 trial.

BACKGROUND: Poly(ADP-ribose) polymerase (PARP) inhibitors have antitumour activity against metastatic castration-resistant prostate cancers with DNA damage response (DDR) alterations in genes involved directly or indirectly in homologous recombination repair (HRR). In this study, we assessed the PARP inhibitor talazoparib in metastatic castration-resistant prostate cancers with DDR-HRR alterations. METHODS: In this open-label, phase 2 trial (TALAPRO-1), participants were recruited from 43 hospitals, cancer centres, and medical centres in Australia, Austria, Belgium, Brazil, France, Germany, Hungary, Italy, the Netherlands, Poland, Spain, South Korea, the UK, and the USA. Patients were eligible if they were men aged 18 years or older with progressive, metastatic, castration-resistant prostate cancers of adenocarcinoma histology, measurable soft-tissue disease (per Response Evaluation Criteria in Solid Tumors version 1.1 [RECIST 1.1]), an Eastern Cooperative Oncology Group performance status of 0-2, DDR-HRR gene alterations reported to sensitise to PARP inhibitors (ie, ATM, ATR, BRCA1, BRCA2, CHEK2, FANCA, MLH1, MRE11A, NBN, PALB2, RAD51C), had received one or two taxane-based chemotherapy regimens for metastatic disease, and progressed on enzalutamide or abiraterone, or both, for metastatic castration-resistant prostate cancers. Eligible patients were given oral talazoparib (1 mg per day; or 0·75 mg per day in patients with moderate renal impairment) until disease progression, unacceptable toxicity, investigator decision, withdrawal of consent, or death. The primary endpoint was confirmed objective response rate, defined as best overall soft-tissue response of complete or partial response per RECIST 1.1, by blinded independent central review. The primary endpoint was assessed in patients who received study drug, had measurable soft-tissue disease, and had a gene alteration in one of the predefined DDR-HRR genes. Safety was assessed in all patients who received at least one dose of the study drug. This study is registered with ClinicalTrials.gov, NCT03148795, and is ongoing. FINDINGS: Between Oct 18, 2017, and March 20, 2020, 128 patients were enrolled, of whom 127 received at least one dose of talazoparib (safety population) and 104 had measurable soft-tissue disease (antitumour activity population). Data cutoff for this analysis was Sept 4, 2020. After a median follow-up of 16·4 months (IQR 11·1-22·1), the objective response rate was 29·8% (31 of 104 patients; 95% CI 21·2-39·6). The most common grade 3-4 treatment-emergent adverse events were anaemia (39 [31%] of 127 patients), thrombocytopenia (11 [9%]), and neutropenia (ten [8%]). Serious treatment-emergent adverse events were reported in 43 (34%) patients. There were no treatment-related deaths. INTERPRETATION: Talazoparib showed durable antitumour activity in men with advanced metastatic castration-resistant prostate cancers with DDR-HRR gene alterations who had been heavily pretreated. The favourable benefit-risk profile supports the study of talazoparib in larger, randomised clinical trials, including in patients with non-BRCA alterations. FUNDING: Pfizer/Medivation.

Efficacy of systemic therapies in men with metastatic castration resistant prostate cancer harboring germline ATM versus BRCA2 mutations.

BACKGROUND: Among men with metastatic prostate cancer, about 10% have germline alterations in DNA damage response genes. Most studies have examined BRCA2 alone or an aggregate of BRCA1/2 and ATM. Emerging data suggest that ATM mutations may have distinct biology and warrant individual evaluation. The objective of this study is to determine whether response to prostate cancer systemic therapies differs between men with germline mutations in ATM (gATM) and BRCA2 (gBRCA2). METHODS: This is an international multicenter retrospective matched cohort study of men with prostate cancer harboring gATM or gBRCA2. PSA50 response (≥50% decline in prostate-specific antigen) was compared using Fisher's exact test. RESULTS AND LIMITATIONS: The study included 45 gATM and 45 gBRCA2 patients, matched on stage and year of germline testing. Patients with gATM and gBRCA2 had similar age, Gleason grade, and PSA at diagnosis. We did not observe differences in PSA50 responses to abiraterone, enzalutamide, or docetaxel in metastatic castration resistant prostate cancer between the two groups; however, 0/7 with gATM and 12/14 with gBRCA2 achieved PSA50 response to PARPi (p < .001). Median (95% confidence interval) overall survival from diagnosis to death was 10.9 years (9.5-not reached) versus 9.9 years (7.1-not reached, p = .07) for the gATM and gBRCA2 cohorts, respectively. Limitations include the retrospective design and lack of mutation zygosity data. CONCLUSIONS: Conventional therapies can be effective in gATM carriers and should be considered before PARPi, which shows limited efficacy in this group. Men with gATM mutations warrant prioritization for novel treatment strategies.
