RESUMO

INTRODUCTION: The addition of compulsive sexual behavior disorder (CSBD) into the ICD-11 chapter on mental, behavioral, or neurodevelopmental disorders has greatly stimulated research and controversy around compulsive sexual behavior, or what has been termed "hypersexual disorder," "sexual addiction," "porn addiction," "sexual compulsivity," and "out-of-control sexual behavior." OBJECTIVES: To identify where concerns exist from the perspective of sexual medicine and what can be done to resolve them. METHODS: A scientific review committee convened by the International Society for Sexual Medicine reviewed pertinent literature and discussed clinical research and experience related to CSBD diagnoses and misdiagnoses, pathologizing nonheteronormative sexual behavior, basic research on potential underlying causes of CSBD, its relationship to paraphilic disorder, and its potential sexual health consequences. The panel used a modified Delphi method to reach consensus on these issues. RESULTS: CSBD was differentiated from other sexual activity on the basis of the ICD-11 diagnostic criteria, and issues regarding sexual medicine and sexual health were identified. Concerns were raised about self-labeling processes, attitudes hostile to sexual pleasure, pathologizing of nonheteronormative sexual behavior and high sexual desire, mixing of normative attitudes with clinical distress, and the belief that masturbation and pornography use represent "unhealthy" sexual behavior. A guide to CSBD case formulation and care/treatment recommendations was proposed. CONCLUSIONS: Clinical sexologic and sexual medicine expertise for the diagnosis and treatment of CSBD in the psychiatric-psychotherapeutic context is imperative to differentiate and understand the determinants and impact of CSBD and related "out-of-control sexual behaviors" on mental and sexual well-being, to detect forensically relevant and nonrelevant forms, and to refine best practices in care and treatment. Evidence-based, sexual medicine-informed therapies should be offered to achieve a positive and respectful approach to sexuality and the possibility of having pleasurable and safe sexual experiences.

RESUMO

Clinical data revealed that KRAS mutant tumors, while initially sensitive to treatment, rapidly bypass KRAS dependence to acquire a drug-tolerant phenotype. However, the mechanisms underlying the transition from a drug-sensitive to a drug-tolerant state still elude us. Here, we show that global chromatin reorganization is a recurrent and specific feature of KRAS-dependent cells that tolerated KRAS silencing. We show that KRAS-dependent cells undergo G0/G1 cell cycle arrest after KRAS silencing, presenting a transcriptomic signature of quiescence. Proteomic analysis showed upregulated chromatin-associated proteins and transcription-associated biological processes. Accordingly, these cells shifted euchromatin/heterochromatin states, gained topologically associating domains, and altered the nanoscale physical organization of chromatin, more precisely by downregulating chromatin packing domains, a feature associated with the induction of quiescence. In addition, they also accumulated transcriptional alterations over time leading to a diversification of biological processes, linking chromatin alterations to transcriptional performance. Overall, our observations pinpoint a novel molecular mechanism of tolerance to KRAS oncogenic loss driven not by specific gene alterations but by global reorganization of genomic information, in which cells transition chromatin domain structure towards a more quiescent state and gain transcriptional reprogramming capacity.

RESUMO

OBJECTIVE: We analyzed adult ADHD symptoms in a cross-cultural context, including investigating the occurrence and potential correlates of adult ADHD and psychometric examination of the Adult ADHD Self-Report Scale (ASRS) Screener. METHOD: Our analysis is based on a large-scale research project involving 42 countries (International Sex Survey, N=72,627, 57% women, Mage=32.84; SDage=12.57). RESULTS: The ASRS Screener demonstrated good reliability and validity, along with partial invariance across different languages, countries, and genders. The occurrence of being at risk for adult ADHD was relatively high (21.4% for women, 18.1% for men). The highest scores were obtained in the US, Canada, and other English-speaking Western countries, with significantly lower scores among East Asian and non-English-speaking European countries. Moreover, ADHD symptom severity and occurrence were especially high among gender-diverse individuals. Significant associations between adult ADHD symptoms and age, mental and sexual health, and socioeconomic status were observed. CONCLUSIONS: Present results show significant cross-cultural variability in adult ADHD occurrence as well as highlight important factors related to adult ADHD. Moreover, the importance of further research on adult ADHD in previously understudied populations (non-Western countries) and minority groups (gender-diverse individuals) is stressed. Lastly, the present analysis is consistent with previous evidence showing low specificity of adult ADHD screening instruments and contributes to the current discussion on accurate adult ADHD screening and diagnosis.

RESUMO

BACKGROUND: Depression and anxiety are among the most prevalent mental health issues experienced worldwide. However, whereas cross-cultural studies utilize psychometrically valid and reliable scales, fewer can meaningfully compare these conditions across different groups. To address this gap, the current study aimed to psychometrically assess the Brief Symptomatology Index (BSI) in 42 countries. METHODS: Using data from the International Sex Survey (N = 82,243; Mage = 32.39; SDage = 12.52; women: n = 46,874; 57 %), we examined the reliability of depression and anxiety symptom scores of the BSI-18, as well as evaluated evidence of construct, invariance, and criterion-related validity in predicting clinically relevant variables across countries, languages, genders, and sexual orientations. RESULTS: Results corroborated an invariant, two-factor structure across all groups tested, exhibiting excellent reliability estimates for both subscales. The 'caseness' criterion effectively discriminated among those at low and high risk of depression and anxiety, yielding differential effects on the clinical criteria examined. LIMITATIONS: The predictive validation was not made against a clinical diagnosis, and the full BSI-18 scale was not examined (excluding the somatization sub-dimension), limiting the validation scope of the BSI-18. Finally, the study was conducted online, mainly by advertisements through social media, ultimately skewing our sample towards women, younger, and highly educated populations. CONCLUSIONS: The results support that the BSI-12 is a valid and reliable assessment tool for assessing depression and anxiety symptoms across countries, languages, genders, and sexual orientations. Further, its caseness criterion can discriminate well between participants at high and low risk of depression and anxiety.

RESUMO

Antibiotic treatments have detrimental effects on the microbiome and lead to antibiotic resistance. To develop a phage therapy against a diverse range of clinically relevant Escherichia coli, we screened a library of 162 wild-type (WT) phages, identifying eight phages with broad coverage of E. coli, complementary binding to bacterial surface receptors, and the capability to stably carry inserted cargo. Selected phages were engineered with tail fibers and CRISPR-Cas machinery to specifically target E. coli. We show that engineered phages target bacteria in biofilms, reduce the emergence of phage-tolerant E. coli and out-compete their ancestral WT phages in coculture experiments. A combination of the four most complementary bacteriophages, called SNIPR001, is well tolerated in both mouse models and minipigs and reduces E. coli load in the mouse gut better than its constituent components separately. SNIPR001 is in clinical development to selectively kill E. coli, which may cause fatal infections in hematological cancer patients.

RESUMO

Τhe aim of this study was to provide a detailed understanding of unprompted audience responses to a literary story of female-on-male rape on Goodreads. Thematic analysis of 429 reviews revealed 5 key themes and 16 sub-themes, which evolved around appraising the social function of the book, evaluating its literary features, assessing the depiction of female-on-male rape especially in terms of its perceived realism, as well as around a variety of explicitly emotional and cognitive responses. The esthetic features of the story proved to be of particular importance for shaping reader engagement. Reflective elaborations on the female rapist were found to constitute a marginal response pattern. Findings identified the existence of an overarching cognitive schema that construes sexual victimization as feminized and is linked to a tripartite pattern of comprehending female on- male rape (female-focused, gender-inclusive, gender-neutral). The study highlights the persistence of gendered rape myths structured around an "ideal victim" - "ideal offender" paradigm, which, however, co-exist with alternative responses oriented toward de-gendering sexual victimization. These findings suggest the importance of addressing audience responses in future investigations of female sexual violence (hands-on and hands-off behaviors) and pursuing an interventional agenda of more inclusive conceptualizations of victimization.

RESUMO

PURPOSE: Independence in activities of daily living (ADLs) is associated with quality of life (QoL) in individuals with dementia. However, the contribution of physical and cognitive functions to this relationship needs further examination. This study aims to examine the mediating effect of physical fitness and cognitive function in the relationship between independence in basic ADLs and QoL among older adults with dementia. METHODS: This cross-sectional study included 107 older adults with dementia (74.8% women; age 78.21 ± 7.70 years). Independence in basic ADL and QoL were evaluated using the Barthel Index (BI) and QoL- Alzheimer's Disease Scale, respectively. The Alzheimer's Disease Assessment Scale-Cognitive Subscale and the Mini-Mental State Examination were applied to assess cognitive function. Physical fitness was evaluated using the 30-s chair stand, 2-min step and the Timed-Up and Go tests. A structural equation modelling (SEM) with bootstrapping estimation was conducted to determine the relationship between all variables. RESULTS: Independence in basic ADL positively affected QoL and this association was mediated by physical fitness (ß = 0.242, p = 0.011). No statistically significant results were observed when testing cognitive function as a mediator between BI and QoL (ß = 0.009, p = 0.345). CONCLUSIONS: Physical fitness (i.e., lower body strength, aerobic capacity, and mobility) plays a role in the relationship between basic ADL independence and QoL of older adults with dementia, reinforcing the need to improve and monitor these parameters throughout the disease progression. Future longitudinal studies should explore the temporal relationship between physical and cognitive function and its contribution to basic ADL independence and QoL.

RESUMO

BACKGROUND: There is an urgent need to support primary care organisations in implementing safe and high-quality virtual consultations. We have previously performed qualitative research to capture the views of 1600 primary care physicians across 20 countries on the main benefits and challenges of using virtual consultations. Subsequently, a prototype of a framework to guide the implementation of high-quality virtual primary care was developed. AIM: To explore general practitioners' perspectives on the appropriateness and relevance of each component of the framework's prototype, to further refine it and optimise its practical use in primary care facilities. METHODS AND ANALYSIS: Participants will be primary care physicians with active experience providing virtual care, recruited through convenience and snowball sampling. This study will use a systematic and iterative online Delphi research approach (eDelphi), with a minimum of three rounds. A pre-round will be used to circulate items for initial feedback and adjustment. In subsequent rounds, participants will be asked to rate the relevance of the framework's components. Consensus will be defined as >70% of participants agreeing/strongly agreeing or disagreeing/strongly disagreeing with a component. Data will be collected using structured online questionnaires. The primary outcome of the study will be a list of the essential components to be incorporated in the final version of the framework. ETHICS AND DISSEMINATION: The study has received ethical approval conceded by the Imperial College London Science, Engineering and Technology Research Ethics Committee (SETREC) (reference no .6559176/2023). Anonymous results will be made available to the public, academic organisations and policymakers.

RESUMO

A global survey among dentists was used to identify the various impacts of the COVID-19 pandemic on this professional group. Special attention was given to perception and assessment of infection risk. From May to August 2020, the questionnaire was delivered in 36 countries by respective research groups and was completed by 52,491 dental professionals. The survey was designed as a cross-sectional survey based on a previously standardized questionnaire. This study focuses on the part of the questionnaire that deals with the perception of the infection risk of COVID-19 by dentists and their patients. A logistic regression model was used, which consisted of four Likert items as response options and the additional self-reported routine or emergency treatment as the dependent variable. Analysis by continent found that European and Asian dentists were particularly likely to be infected at work (OR = 1.45 95%CI = 1.02/1.84 and OR = 2.68, 95%CI = 1.45/3.22, respectively), while it was likely that Australian dentists did not feel particularly at risk due to low infection rates. Three quarters of Americans treated only emergencies during this survey period, while Europeans (64.71%) and Asians (66.67%) provided mostly routine care. This could affect the Europeans' confidence that they would not be able to protect themselves from infections in the long-term. The COVID-19 pandemic and its impact on dental professionals' infection risk perception is determined by the geographical origin of dentists. This study shows that, especially in high-incidence countries, infection risk perception was higher when dentists tried to provide routine dental procedures to their patients. Dental professionals can offer themselves and their patients good protection by maintaining high standards of hygiene. However, their concerns should be taken seriously and the dental professionals' group that is of great importance for oral health care and prevention, should not be neglected in the future, even in the event of emerging pandemics.

RESUMO

The current study aimed at translating and validating the TSMQ into Portuguese-European (TSMQ-PT) and to investigate its psychometric properties. Three online studies were conducted with independent samples collected between September 2020 and March 2022. Study 1 tested the exploratory factorial structure (N = 325; 206 women); Study 2 explored the confirmatory factorial structure and construct validity (N = 450; 230 women); and Study 3 examined the temporal stability of the TSMQ-PT (N = 30; 15 women). Participants completed the TSMQ-PT for all three studies. In study 2, further completed the Sexual Compulsivity Scale, the Sexual Sensation Seeking Scale, and the Sexual Desire Inventory. Data revealed that the TSMQ-PT yielded a four-structure model, (i.e., Sexually Oriented, Comparison with Others, Seeking for Sexual Encounters, and Importance of Sex) comprising 13 items, with seven additional items for assessing existence and number of sexual partners, and frequency of sexual behaviors. The TSMQ-PT achieved good internal consistency levels (McDonald's omega ranged from .71 to .89) and construct validity, and temporal stability over 10-11 months (values ranged from .80 to .87) supporting the trait-dimension of sexual motivation. Current findings support a brief, valid, and reliable self-report instrument for assessing sexual motivation in the Portuguese context.

RESUMO

INTRODUCTION: Prostate cancer is the second-most prevalent cancer diagnosis worldwide among males. Although prostate cancer affects the physical, sexual, and mental health of patients, the impact of prostate cancer on partners has also been increasingly recognized. Hence, taking a dyadic approach is of relevance. Moreover, there is evidence of the utility of dyadic approaches to the study of relational stress that chronic diseases such as prostate cancer can bring to couples, even though knowledge is sparse about prostate cancer. OBJECTIVES: This scoping review aimed to map existing dyadic studies on the psychosocial adaptation of couples to prostate cancer. METHODS: A systematic search of studies published from 2005 to November 2022 was conducted on electronic databases (PubMed, Cochrane Library, EBSCOHost, Scopus, and Web of Science) following PRISMA-ScR (Preferred Reporting Items for Systematic Reviews and Meta-analyses-Extension for Scoping Reviews). RESULTS: The review included 25 eligible studies from the initial 2514 articles retrieved. Overall, the results emphasized the interdependency between couple members and suggested how partners' adaptation influences patients' adaptation to prostate cancer and vice versa, regarding several psychosocial dimensions (eg, intimacy, quality of life). CONCLUSIONS: This work can bring awareness to health care professionals to adopt a couples approach when managing prostate cancer whenever there is a partner, due to these interdependent influences. For researchers and future studies, this work can strengthen the relevance of dyadic approaches on how couples adapt to prostate cancer and explore which other dimensions influence these complex dynamics.

RESUMO

BACKGROUND: Neuropsychiatric symptoms (NPS) are highly prevalent among individuals with major neurocognitive disorders (MNCD). OBJECTIVE: Here, we characterized blood biomarkers (metabolic, inflammatory, neurotrophic profiles and total antioxidant), body composition, physical fitness and quality of life (QoL) in individuals with MNCD according to NPS. METHODS: The sample comprised 34 older adults (71.4% women; 74.06±6.03 yrs, with MNCD diagnosis) categorized according to 50th percentile [Low (≤12) or High (≥13)] for NPS (Neuropsychiatric Inventory Questionnaire). Sociodemographic, clinical data, body composition, anthropometric, cognitive assessment (ADAS-Cog), physical fitness (Senior Fitness Test), QoL (QoL-Alzheimer's Disease scale) were evaluated, and blood samples were collected for biochemical analysis. RESULTS: Low compared to high NPS group showed higher levels of IL-6, IGF-1and neurotrophic zscore (composite of IGF-1, VEGF-1, BDNF). Additionally, low compared to high NPS group have higher QoL, aerobic fitness and upper body and lower body strength. CONCLUSION: The severity of NPS seems to be related to modified neurotrophic and inflammatory outcomes, lower physical fitness, and poor QoL. Strategies to counteract NPS development may preserve the physical and mental health of individuals with MNCD.

RESUMO

INTRODUCTION: Despite being a widely used screening questionnaire, there is no consensus on the most appropriate measurement model for the Alcohol Use Disorders Identification Test (AUDIT). Furthermore, there have been limited studies on its measurement invariance across cross-cultural subgroups, genders, and sexual orientations. AIMS: The present study aimed to examine the fit of different measurement models for the AUDIT and its measurement invariance across a wide range of subgroups by country, language, gender, and sexual orientation. METHODS: Responses concerning past-year alcohol use from the participants of the cross-sectional International Sex Survey were considered (N = 62,943; Mage: 32.73; SD = 12.59). Confirmatory factor analysis, as well as measurement invariance tests were performed for 21 countries, 14 languages, three genders, and four sexual-orientation subgroups that met the minimum sample size requirement for inclusion in these analyses. RESULTS: A two-factor model with factors describing 'alcohol use' (items 1-3) and 'alcohol problems' (items 4-10) showed the best model fit across countries, languages, genders, and sexual orientations. For the former two, scalar and latent mean levels of invariance were reached considering different criteria. For gender and sexual orientation, a latent mean level of invariance was reached. CONCLUSIONS: In line with the two-factor model, the calculation of separate alcohol-use and alcohol-problem scores is recommended when using the AUDIT. The high levels of measurement invariance achieved for the AUDIT support its use in cross-cultural research, capable also of meaningful comparisons among genders and sexual orientations.

RESUMO

Informal caregivers of people with neurocognitive disorders (NCDs) may play a decisive role in guaranteeing partners' participation in community-based physical exercise interventions. However, little is still known about their perspective on being involved in such programs that are specifically designed for their partners. This study aimed to explore the views of caregivers of people with NCDs about taking part in a multicomponent physical exercise intervention with their partners and to explore the perceived impact of this program on those caregivers who enrolled in it. An exploratory qualitative study was conducted with 20 caregivers (67.5 ± 13.94 years; seven female) from the "Body & Brain" project. Ten took part in the physical exercise sessions (active-participating caregivers), and the others did not (social-participating caregivers). Data retrieved from semi-structured interviews were analyzed following a thematic analysis approach. Regardless of their participation level, all caregivers reported their inclusion to be important in enhancing their partners' initiation and engagement in the sessions; also, they all identified personal gains. Active-participating caregivers reported exercise-related benefits on general health, enjoyment, and social connectedness. Social-participating caregivers considered this intervention an opportunity for respite and appreciated being involved only occasionally (i.e., occasional gatherings or telephone contacts). The findings support the inclusion of caregivers in physical exercise interventions designed for partners with NCDs, considering their decisive role in the partners' adherence and engagement and due to the perceived gains. Future community-based interventions designed for people with NCDs should consider giving caregivers the opportunity to choose whether they want or not to be actively involved in the exercise sessions. Further studies with larger samples are needed to verify these results, comparing caregivers' point of view at baseline and post-intervention.

RESUMO

CONTEXT: Recommendations regarding the management of penile size abnormalities and dysmorphophobia are important in guiding evidence-based clinical practice. OBJECTIVE: To present a summary of the 2023 European Association of Urology sexual and reproductive health evidence-based recommendations for the management of penile size abnormalities and dysmorphophobia. EVIDENCE ACQUISITION: A broad and comprehensive scoping exercise covering all areas of the guidelines was performed. Databases searched included Medline, EMBASE, and the Cochrane Libraries. A level of evidence and a strength of recommendation were assigned for each recommendation according to the evidence identified. The evidence cutoff date for the 2023 guidelines is June 1, 2022. EVIDENCE SYNTHESIS: Well-structured studies reporting high level of evidence, with standardized PROMS were deficient on penile size abnormalities and dysmorphohobia. A shared definition for short penis/micropenis was also lacking. Categorisation of penile abnormalities according to congenital, acquired, and dysmorphophobic aetiology is deemed compulsory. A detailed medical and psychosexual history and precise measurements of penile size are essential in the diagnostic pathway. Patients with normal penile size who are seeking penile augmentation should be referred for psychological evaluation for potential dysmorphophobic disorders. Penile length and girth enhancements can be achieved via a multitude of treatments, but a personalised management plan is crucial for satisfactory results. Endocrinological therapies, when indicated, are effective in the prepubertal setting only. Vacuum therapy has a limited evidence base in treatment protocols, although acceptable outcomes have been reported for penile traction therapy. Surgical techniques to enhance penile length and girth have limited evidence and should only be proposed after extensive patient counselling. CONCLUSIONS: Management of penile abnormalities and dysmorphophobia is a complex issue with considerable ethical concerns. The adoption of a structured diagnostic and therapeutic pathway is crucial, as recommended in the guidelines. PATIENT SUMMARY: Requests for medical/surgical treatments to increase penis size have increased dramatically worldwide. Several conservative and surgical treatments are available. However, few patients receive clear information on the benefits and possible harms of these treatments. These guidelines aim to provide a structured path to guide both physicians and patients in the selection of appropriate treatment(s) to increase penis size.

RESUMO

Several developments over the last few years are being directed toward improving DNA-based analysis to simplify, miniaturize, and reduce the time and cost of analysis, with the objective to allow its use in decentralized settings. One of the most interesting fields is DNA extraction and purification, a key step for ensuring good analytical performance. In this sense, microscale solid phase extraction (µSPE) offers paramount advantages for an improved DNA yield. In this work, we have developed a miniaturized module for DNA purification based on µSPE using a borosilicate glass microfiber filter as the solid phase. We also established a protocol for highly efficient DNA purification from vegetable samples, including leaves and grapes from four different varieties from the PDO Douro and two varieties from the Minho wine regions. The protocol demonstrated excellent performance when compared with a commercial kit with a DNA recovery yield of around 50%.

RESUMO

Understanding the dynamics of stability/plasticity balances during adulthood is pivotal for learning, disease, and recovery from injury. However, the brain-wide topography of sensory remapping remains unknown. Here, using a first-of-its-kind setup for delivering patterned visual stimuli in a rodent magnetic resonance imaging (MRI) scanner, coupled with biologically inspired computational models, we noninvasively mapped brain-wide properties-receptive fields (RFs) and spatial frequency (SF) tuning curves-that were insofar only available from invasive electrophysiology or optical imaging. We then tracked the RF dynamics in the chronic visual deprivation model (VDM) of plasticity and found that light exposure progressively promoted a large-scale topographic remapping in adult rats. Upon light exposure, the initially unspecialized visual pathway progressively evidenced sharpened RFs (smaller and more spatially selective) and enhanced SF tuning curves. Our findings reveal that visual experience following VDM reshapes both structure and function of the visual system and shifts the stability/plasticity balance in adults.

RESUMO

The aim of this study was to evaluate and quantify, in vitro, the extent of coronal discoloration induced by bioceramic materials over time. In total, 44 human monoradicular teeth were divided into four groups (n = 11), according to the applied material: Negative control (NC); White MTA ProRoot® (WMTAP); Biodentine™ (BD); and TotalFill® BC RRM™ Putty (TF). Teeth were immersed in saline solution and incubated at 37 °C; the following periods of time were defined: before incubation: [t0]-without bioceramic material, t1-immediately after the bioceramic material placement; after incubation: t24h-24 h, t7d-7 days, and 30d-30 days. Descriptive and inferential statistical analysis were performed. Cochran's Q test was used to evaluate coronal discoloration across the different groups, while the Kruskal-Wallis test was employed to determine differences in discoloration among the groups at each time interval. Additionally, the Friedman test was applied to analyze the variations in discoloration within each group over time. A significance level of 5% was set. All experimental groups revealed coronal discoloration over time: NC (p = 0.001), WMTAP (p < 0.001), BD (p = 0.001), and TF (p = 0.006). No significant differences were observed between groups for each time interval (p > 0.05). The WMTAP group varied the most considering the intervals [t0-t1] and [t24h-t7d] (p = 0.037) compared to the remaining experimental groups.

RESUMO

The Alcohol, Smoking and Substance Involvement Screening Test (ASSIST) is an instrument to screen substance-use-related health risks. However, little is known whether the ASSIST could be further shortened while remaining psychometrically sound across different countries, languages, gender identities, and sexual-orientation-based groups. The study aimed to validate a shortened 11-item ASSIST (ASSIST-11). Using the International Sex Survey data, 82,243 participants (M age = 32.39 years) across 42 countries and 26 languages completed questions from the ASSIST-11 regarding gender identity, sexual orientation, and other information. Confirmatory factor analysis (CFA) and multigroup CFA (MGCFA) evaluated the ASSIST-11's structure and tested measurement invariance across groups. Cronbach's α and McDonald's ω were used to examine the internal consistency. Cohen's d and independent t-tests were used to examine known-group validity. The ASSIST-11 was unidimensional across countries, languages, age groups, gender identities (i.e., men, women, and gender-diverse individuals), and sexual orientations (i.e., heterosexual and sexual minority individuals). Cronbach's α was 0.63 and McDonald's ω was 0.68 for the ASSIST-11. Known-group validity was supported by Cohen's d (range between 0.23 and 0.40) with significant differences (p-values<0.001). The ASSIST-11 is a modified instrument with a unidimensional factor structure across different languages, age groups, countries, gender identities, and sexual orientations. The low internal consistency of the ASSIST-11 might be acceptable as it assesses a broad concept (i.e., use of several different substances). Healthcare providers and researchers may use the ASSIST-11 to quickly assess substance-use information from general populations and evaluate the need to follow up with more detailed questions about substance use.

RESUMO

INTRODUCTION: Prostate cancer (PCa) is the second-most frequently diagnosed oncologic condition among biological men, affecting physical and psychological well-being, as well as sexual health and quality of life. Prior research has shown that cognitive-behavioral therapy (CBT) can be effective in addressing a range of psychological and sexual problems but also in improving the sexual and mental health of survivors of PCa. OBJECTIVES: This systematic review aimed to methodically research and summarize results concerning the efficacy of CBT in the mental and sexual health of survivors of PCa. METHODS: A systematic search was carried out via electronic databases until August 2022 (EBSCO, MEDLINE, Cochrane Library, and Web of Science). By combining specific search words and following the PRISMA checklist, we identified 15 eligible articles among 8616 initial records. RESULTS: Four studies showed evidence of intervention efficacy for the improvement of sexual health, specifically for overall sexual function, erectile function, sexual desire, and sexual satisfaction. Eight studies found intervention efficacy for the improvement of mental health dimensions, such as psychological distress, depressive symptoms, anxiety, and quality of life. CONCLUSION: There is evidence that CBT interventions have the potential to effectively promote mental and sexual health in survivors of PCa, but further research comprising larger and more diverse populations is needed. Future studies should focus on understanding mechanisms of change through CBT interventions to ensure the mental and sexual health of survivors of PCa.
