RESUMO
BACKGROUND: Brugada syndrome poses significant challenges in terms of risk stratification and management, particularly for asymptomatic patients who comprise the majority of individuals exhibiting Brugada ECG pattern (BrECG). The aim of this study was to evaluate the long-term prognosis of a large cohort of asymptomatic patients with BrECG. METHODS: Asymptomatic patients with BrECG (1149) were consecutively collected from 2 Italian centers and followed-up at least annually for 2 to 22 years. For the 539 asymptomatic patients (men, 433 [80%]; mean age, 46±13 years) with spontaneous type 1 documented on baseline ECG (87%) or 12-lead 24-hour Holter monitoring (13%), an electrophysiologic study (EPS) was proposed; for the 610 patients with drug-induced-only type 1 (men, 420 [69%]; mean age, 44±14 years), multiple ECGs and 12-lead Holter were advised in order to detect the occurrence of a spontaneous type-1 BrECG. Arrhythmic events were defined as sudden death or documented ventricular fibrillation or tachycardia. RESULTS: Median follow-up was 6 (4-9) years. Seventeen (1.5%) arrhythmic events occurred in the overall asymptomatic population (corresponding to an event-rate of 0.2% per year), including 16 of 539 (0.4% per year) in patients with spontaneous type-1 BrECG and 1 of 610 in those with drug-induced type-1 BrECG (0.03% per year; P<0.001). EPS was performed in 339 (63%) patients with spontaneous type-1 BrECG. Patients with spontaneous type-1 BrECG and positive EPS had significantly higher event rates than patients with negative EPS (7 of 103 [0.7% per year] versus 4 of 236 [0.2% per year]; P=0.025). Among 200 patients who declined EPS, 5 events (0.4% per year) occurred. There was 1 device-related death. CONCLUSIONS: The entire population of asymptomatic patients with BrECG exhibits a relatively low event rate per year, which is important in view of the long life expectancy of these young patients. The presence of spontaneous type-1 BrECG associated with positive EPS identifies a subgroup at higher risk. Asymptomatic patients with drug-induced-only BrECG have a minimal arrhythmic risk, but ongoing follow-up with 12-lead Holter monitoring is recommended to detect the appearance of spontaneous type-1 BrECG pattern.

BACKGROUND: Transgender women are disproportionately affected by both HIV and gender-based violence (GBV), defined as physical, sexual, or emotional violence perpetrated against an individual based on their gender identity/expression. While a growing body of evidence demonstrates that GBV leads to poor HIV care and treatment outcomes among cisgender women, less research has examined this association among transgender women. We assessed the impact of lifetime experiences of GBV on subsequent retention in HIV care and laboratory confirmed viral suppression among a sample of transgender women living with HIV (TWH) in Brazil. METHODS: A pilot trial of a peer navigation intervention to improve HIV care and treatment among TWH was conducted in São Paulo, Brazil between 2018 and 2019. TWH were recruited and randomized into the intervention or control arm and participated in a baseline and 9-month follow-up survey and ongoing extraction of clinical visit, prescribing, and laboratory data. Generalized linear model regressions with a Poisson distribution estimated the relative risk (RR) for the association of lifetime physical and sexual violence reported at baseline with treatment outcomes (retention in HIV care and viral suppression) at follow-up, adjusting for baseline sociodemographic characteristics. RESULTS: A total of 113 TWH participated in the study. At baseline, median age was 30 years, and the prevalence of lifetime physical and sexual violence was 62% and 45%, respectively. At follow-up, 58% (n = 66/113) were retained in care and 35% (n = 40/113) had evidence of viral suppression. In adjusted models, lifetime physical violence was non-significantly associated with a 10% reduction in retention in care (aRR: 0.90, 95% CI: 0.67, 1.22) and a 31% reduction in viral suppression (aRR: 0.69; 95% CI: 0.43, 1.11). Lifetime sexual violence was non-significantly associated with a 28% reduction in retention in HIV care (aRR: 0.72, 95% CI: 0.52, 1.00) and significantly associated with a 56% reduction in viral suppression (aRR: 0.44; 95% CI: 0.24, 0.79). CONCLUSION: Our findings are among the first to demonstrate that lifetime experiences with physical and sexual violence are associated with poor HIV outcomes over time among transgender women. Interventions seeking to improve HIV treatment outcomes should assess and address experiences of GBV among this population. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT03525340.

Rationale: Patients discharged from the hospital for chronic obstructive pulmonary disease (COPD) exacerbation have impaired quality of life and frequent readmission and death. Clinical trials to reduce readmission demonstrate inconsistent results, including some demonstrating potential harms. Objectives: We tested whether a pragmatic proactive interdisciplinary and virtual review of patients discharged after hospitalization for COPD exacerbation would improve quality of life, using the Clinical COPD Questionnaire, and reduce all-cause 180-day readmission and/or mortality. Methods: We performed a stepped-wedge clinical trial. We enrolled primary care providers and their patients after hospital discharge for COPD at two Department of Veterans Affairs medical centers and 10 outpatient clinics. A multidisciplinary team reviewed health records and developed treatment recommendations delivered to primary care providers via E-consult. We facilitated uptake by entering recommendations as unsigned orders that could be accepted, modified, or canceled. Providers and patients made all final treatment decisions. Measurements and Main Results: We enrolled 365 primary care providers. Over a 30-month period, 352 patients met eligibility criteria, with 191 (54.3%) patients participating in the control and 161 (45.7%) in the intervention. The intervention led to clinically significant better Clinical COPD Questionnaire scores (-0.47; 95% confidence interval [CI], -0.85 to -0.09; 52.6% missing) but did not reduce 180-day readmission and/or mortality (adjusted odds ratio, 0.83; 95% CI, 0.49 to 1.38), in part because of wide CIs. Among the 161 patients in the intervention group, we entered 519 recommendations as unsigned orders, of which 401 (77.3%) were endorsed. Conclusions: A pragmatic health system-level intervention that delivered proactive specialty supported care improved quality of life but did not reduce 180-day readmission or death. Clinical trial registered with www.clinicaltrials.gov (NCT02021955).

Higher education students have faced several changes in their lives due to the COVID-19 pandemic. This study aims to explore the effect of dispositional optimism in students' fear of COVID-19 and to test the mediating role of general anxiety in the relationship between optimism and fear. Using an online survey, data were collected during the second wave of the pandemic in Portugal. The sample included 312 higher education students (76% females) aged 18-25 years old, who completed measures of dispositional optimism, general anxiety and fear of COVID-19. The results showed that higher optimism and lower general anxiety reduce fear of COVID-19. Moreover, the link between optimism and fear is fully mediated by general anxiety, showing that optimism reduces fear of COVID-19 indirectly through the reduction of students' anxiety. The role of optimism, anxiety and fear in higher education students is discussed and topics for further research are presented.

BACKGROUND: Trans women have been shown to experience disproportionately poor outcomes in physical and mental health. Although it is common to talk about the violence against trans people, little is still known about mental health outcomes and experiences of suicidality among trans women, particularly in developing countries. This study aims to investigate risk factors and associations with mental health, suicide ideation and suicide attempts among trans women in the largest metropolitan area in Brazil. METHODS: Trans women living in São Paulo were recruited between May 2017 and July 2019 using the long-chain peer referral method Respondent-Driven Sampling. Multivariate regression models were used to investigate the associations with K10 score classification (logistic) and suicidal ideation/suicide attempt (ordinal logistic). RESULTS: A total of 763 trans women were included in the study. Over one quarter (26.5%) of trans women had been diagnosed with anxiety in the past, and close to one in five (19.1%) trans women had received a diagnosis of depression. More than two in five (41.9%) trans women had moderate to severe psychological distress. More than half of all participating trans women reported having previously either experienced suicidal ideation or attempted to take their own lives (25.0 and 31.2% respectively). In multivariate regression, moderate to severe psychological distress was associated with homelessness, income, current sex work, use of stimulant drugs, history of physical abuse, depression diagnosis and access to mental health treatment. Suicidal ideation and suicide attempts were associated with race/skin color, living arrangements, marital status, current sex work, history of sexual violence, depression and PTSD diagnoses, access to mental health treatment and psychological distress. CONCLUSIONS: This study showed that there is a significant association between mental health conditions, lack of treatment for these conditions and suicidality among trans gender women. Findings point to the need for a structural transformation in Brazil that enables a reduction in the social inequality and violence that impact the mental health of trans women. A number of recommendations to achieve this are provided.

Brown adipose tissue (BAT) influences energy balance through nonshivering thermogenesis, and its metabolism daily and seasonal variations are regulated by melatonin through partially known mechanisms. We evaluated the role of melatonin in BAT molecular machinery of male Control, pinealectomized (PINX), and melatonin-treated pinealectomized (PINX/Mel) adult rats. BAT was collected either every 3 hours over 24 hours or after cold or high-fat diet (HFD) acute exposure. HFD PINX animals presented decreased Dio2 expression, while HFD PINX/Mel animals showed increased Dio2, Ucp1, and Cidea expression. Cold-exposed PINX rats showed decreased Dio2 and Lhs expression, and melatonin treatment augmented Adrß3, Dio2, Ucp1, and Cidea expression. Daily profiles analyses showed altered Dio2, Lhs, Ucp1, Pgc1α, and Cidea gene and UCP1 protein expression in PINX animals, leading to altered rhythmicity under sub-thermoneutral conditions, which was partially restored by melatonin treatment. The same was observed for mitochondrial complexes I, II, and IV protein expression and enzyme activity. Melatonin absence seems to impair BAT responses to metabolic challenges, and melatonin replacement reverses this effect, with additional increase in the expression of crucial genes, suggesting that melatonin plays an important role in several key points of the thermogenic activation pathway, influencing both the rhythmic profile of the tissue and its ability to respond to metabolic challenges, which is crucial for the organism homeostasis.

BACKGROUND: Chronic lung diseases, such as COPD, are a growing health concern within the veteran population. Palliative care programs have mainly focused on the needs of people with malignant disease in the past, however the majority of those worldwide needing palliative care have a non-malignant diagnosis. Additionally, palliative care provision can often be fragmented and varied dependent upon a patient's geographical location. This study aimed to explore palliative care provision for veterans with non-malignant respiratory disease, and their family carers, living in a rural area of America. METHODS: Qualitative study involving a convenience sample of 16 healthcare professionals from a large veteran hospital in Boise, Idaho. Data collection consisted of 5 focus groups which were transcribed verbatim and analysed using thematic analysis. RESULTS: Healthcare professionals perceived that a lack of education regarding disease progression enhanced feelings of anxiety amongst veterans with NMRD, and their family carers. Additionally, the uncertain disease trajectory impeded referral to palliative and hospice services due to healthcare professionals own ambiguity regarding the veteran's prognosis. A particular barrier also related to this particular patient population, was a perceived lack of ability to afford relevant services and a lack of local palliative service provision. Healthcare professionals expressed that a compounding factor to palliative care uptake was the perceptions held by the veteran population. Healthcare professionals expressed that alongside aligning palliative care with dying, veterans also viewed accepting palliative care as 'surrendering' to their disease. Findings indicated that telemedicine may be a beneficial platform to which palliative care can be provided to veterans with NMRD, and their family carers, in rural areas using a digital platform. CONCLUSION: Non-malignant respiratory disease is a life limiting condition commonly experienced within the veteran population. A new model of palliative care utilising a dynamic digital platform for this particular veteran population may provide an optimal way of providing efficient holistic care to areas with limited palliative services.

The use of reproductive technologies has expanded beyond cases of infertility, and opportunities for individuals of different sexual orientations to use such technologies for conception have increased. The authors examined the challenges and limitations faced by women in same-sex relationships seeking conception services in São Paulo, Brazil. They interviewed 16 women in same-sex relationships who conceived children using reproductive technologies. Access to public health services for conception remains limited and exclusive to infertile heterosexual couples. Women in same-sex relationships are forced to select between costly medical treatments in the private sector, or self-insemination with sperm from a known donor. In this study, individuals reported that they experienced adverse effects of treatments; were treated with technologies for infertility when they were, in fact, fertile; and were exposed to unnecessary and invasive interventions. Growing political conservatism and the reduction of investment in public health services are factors that can directly affect sexual and reproductive health, including that of lesbians. Public policies that enable same-sex couples to conceive have yet to be developed in many countries, and a clearer articulation of the right to evidence-informed, rights-based care, consistent with national and international guidelines is a much-needed next step.

BACKGROUND: Cardiotoxicity is the major side effect of doxorubicin. As mechanisms that are involved in cardiotoxicity are ambiguous, new methods for attenuating cardiotoxicity are needed. Recent studies have shown that bisphosphonates can decrease oxidative stress. Therefore, the objective of this study was to evaluate the effect of pamidronate on preventing acute doxorubicin-induced cardiotoxicity. METHODS: Sixty-four male Wistar rats were allocated into four groups: the control group (C), the pamidronate group (P), the doxorubicin group (D) and the doxorubicin/pamidronate group (DP). The rats in the P and DP groups received pamidronate injections (3 mg/kg, IP). After 24 hours, the rats in the D and DP groups received doxorubicin injections (20 mg/kg, IP). Forty-eight hours after doxorubicin injection, the rats were killed. Echocardiography, isolated heart study and biochemical analysis were performed. RESULTS: Doxorubicin-induced acute cardiotoxicity showed increased matrix metalloproteinases (MMP)-2 activation, oxidative damage and induced alterations in myocardial energetic metabolism. Pamidronate did not inhibit MMP-2 activation but attenuated oxidative stress and improved myocardial energetic metabolism. Regarding cardiac function, the DP group exhibited a decrease in the left ventricular ejection fraction in the echocardiography and a decrease in +dP/dt in the isolated heart study compared with other groups. The same DP group presented serum hypocalcaemia. CONCLUSIONS: Despite its ability to reduce oxidative stress and improve energy metabolism in the heart, pamidronate worsened systolic function in rats treated with doxorubicin, and therefore we cannot recommend its use in conjunction with anthracycline chemotherapy.

The objective of this controlled experimental study was to analyze the changes in the Achilles tendons of rats with experimentally induced tendinitis after treatment with platelet-rich plasma (PRP) and/or laser therapies by histometry to quantify fibroblasts and by Raman spectroscopy to determine the biochemical concentration of collagen types I and III. Fifty-four male Wistar rats were divided into six treatment groups: control (G1); PRP only (G2); irradiation with 660 nm laser (G3); irradiation with 830 nm laser (G4); PRP plus 660 nm laser irradiation (G5); and PRP plus 830 nm laser irradiation (G6). Injuries (partial tenotomy) were inflicted in the middle third of the Achilles tendon, with PRP added prior to suture in the appropriate experimental groups. A diode laser (model Laser Flash® III, DMC Equipamentos Ltda, São Carlos, SP, Brazil) that can be operated in two wavelengths 660 and 830 nm was used for irradiation treatments. The irradiation protocol was energy density of 70 J/cm², 20 s irradiation time, and 0.028 cm² spot area, per point in three points in the injured. The histometry was made in micrographical images of the H&E stained sections and evaluated by ImageJ (version 1.46r)®. Raman spectra were collected using a dispersive spectrometer at 830 nm excitation, 200 mW power, and 10 s integration time (P-1 Raman system, Lambda Solutions, Inc. MA, USA). The relative amount of type I collagen was significantly greater in the PRP plus 830 nm laser irradiation group (468 ± 188) than in the control (147 ± 137), 630 nm laser only (191 ± 117), and 830 nm laser only (196 ± 106) groups (p < 0.01), while the quantity of type III collagen was significantly greater in the PRP-only group compared to both irradiated groups without PRP (p < 0.05). Treatment with PRP combined with irradiation at 830 nm resulted in a larger number of fibroblasts and increased concentration of type I collagen, thus accelerating the healing of the injured tendon.

OBJECTIVE: To understand the narratives of transgender women and travestis (TGW) from four Brazilian cities regarding access to and use of health services. METHODS: Qualitative study carried out within the scope of the TransOdara project, cross-sectional multicenter mixed methods research conducted between 2019-2021. Fifty-two in-depth interviews with TGW in Manaus, Campo Grande, Porto Alegre and São Paulo were analyzed. The analysis was guided by philosophical hermeneutics. RESULTS: Reports of discrimination, stigmatization and pathologization reiterate the difficulties faced by TGW in seeking healthcare. The recurrence of disrespect for the social/corrected name reveals obstacles to the recognition of transgender identities and, in some cases, the intention of inhibiting transsexuality-travestilidade. Other difficulties arise from actions that disregard the health specificities of TGW or the precarious social conditions that affect some of them. On the other hand, based on experiences of respect and adequate care, participants identify an ongoing change, which is expressed in greater availability of services and improved assistance. There is an expectation of continued expansion of services, technologies and training of health professionals. CONCLUSIONS: The identified change has been undertaken at the interface of public health policies with LGBT+ activism and the production of knowledge about TGW health needs. Although the identified advances are insufficient to change the scenario of the historical exclusion experienced by TGW in health services, they point to promising ways to improve their health conditions.

This paper investigates the pervasive issue of hate speech within Twitter/X Portuguese network conversations, offering a multifaceted analysis of its characteristics. This study utilizes a mixed-method approach, combining several methodologies of network analysis (triad census and participation shifts) over the network of interaction between users. Qualitative manual content annotation was applied to the dataset to dissect different patterns of hate speech on the platform. Key findings reveal that the number of users followed by an individual and potentially reads is a relevant predictor for a user's propensity to post aggressive content. We concluded also that during a conversation thread, hate speech happens significantly more within the first 2 h of interaction. Transitivity of interactions and individual expression are considerably lower as more hate speech is prevalent in conversations. Our research confirms that hate speech is usually expressed by external individuals who intrude into conversations. Conversely, the expression of hate speech of indirect type by third parties interfering in conversations is uncommon. We also found that counter-speech discourse is strongly correlated with a type of discourse that typically avoids conflict and is not privately held.
RESUMO
CONTEXT.: The main objectives of the Paris System are to detect high-grade urothelial carcinoma, to standardize morphologic criteria and the cytopathologic report, to reduce the prevalence of the atypia category, and to improve the malignancy risk stratification. OBJECTIVE.: To compare the results and sensitivity of cytologic classification before and after reclassification by the Paris System. DESIGN.: Urinary cytology samples from patients with a histologic diagnosis of urothelial carcinoma were reclassified on the basis of the Paris System categories. The diagnoses before reclassification were divided into 5 categories (A, B, C, D, E) and compared with the Paris System (I, II, III, IV, V). Sensitivity was calculated considering cytohistologic agreement in relation to high-grade urothelial carcinoma. RESULTS.: A total of 111 urinary cytology samples from patients were analyzed, corresponding to 40 histologic samples; of these, 12 (30%) were high grade and the remaining were low grade. Comparison of the correlated categories showed an increase from 3 (3 of 111; 2.7%) (A) to 31 (31 of 111; 27.9%) (I) in unsatisfactory cases and a decrease from 67 (67 of 111; 60,0%) to 30 (30 of 111; 27.0%) in negative cases, while the atypia category remained unchanged (15 cases [15 of 111; 13.5%]) (C and III). Suspicious cases increased from 5 (5 of 111; 4.5%) (D) to 14 (14 of 111; 12.6%) (IV) and cases of urothelial carcinoma were unchanged (21 cases [21 of 111; 18.9%]) (E and V). Sensitivity was 69% for the previous classification and 90% for the Paris System. CONCLUSIONS.: The Paris System improved the sensitivity of urinary cytology and the standardization of the unsatisfactory criteria, with an increase of cases in this category and a decrease of cases previously classified as negative among patients with a subsequent histologic diagnosis of urothelial carcinoma.
RESUMO
The objective of this study was to investigate the effects of low-level laser therapy (LLLT) treatment alone (λ = 660 nm and λ = 830 nm) or associated with platelet-rich plasma (PRP). We used 54 male rats divided into six groups, with nine animals each: group 1, partial tenotomy; group 2 (GII), PRP; group 3 (GIII): λ660 nm; group 4 (GIV), λ830 nm; group 5 (GV), PRP + λ660 nm; and group 6 (GVI), PRP + λ830 nm. The protocol used was power density 0.35 W/cm(2), energy 0.2 J, energy density 7.0 J/cm(2), time 20 s per irradiated point, and number of points 3. Animals in groups GII, GV, and GVI received treatment with PRP, consisting of a single dose of 0.2 mL directly into the surgical site, on top of the tenotomy. Animals were killed on the 13th day post-tenotomy and their tendons were surgically removed for a quantitative analysis using polarization microscopy. The percentages of collagen fibers of types I and III were expressed as mean ± SD. Higher values of collagen fibers type I were obtained for groups GV and GVI when compared with all other groups (p < 0.05), whereas groups GIII and GIV showed no significant difference between them (p > 0.05). For collagen type III, a significant difference was observed between GII and all other groups (p < 0.5), but no significant difference was found between GIII and GIV and between GV and GVI. Results showed that the deposition of collagen type I was higher when treatment with PRP and LLLT was combined, suggesting a faster regeneration of the tendon.

Travestis and transgender women (TrTGW) constitute the groups with the highest HIV prevalence in the world, with higher probability of infection compared with the general population and lower adherence to prevention and treatment strategies than other vulnerable groups. Considering these challenges, this study describes the factors associated with the retention of TrTGW with HIV to the TransAmigas project. Participants were recruited from April 2018 to September 2019 in a public health service in São Paulo, Brazil. A total of 113 TrTGW were randomly assigned to either a peer navigation intervention (75) or a control group (38) and followed up for nine months. To analyze the association between the selected variables and the outcome ("retention at nine months", regardless of contact at three months, defined by the "full completion of the final questionnaire"), bivariate and multivariate logistic regression models were used. Peer contact forms were qualitatively assessed to validate and complement the previous selection of quantitative component variables. Of the 113 participants, 79 (69.9%) participated in the interview after nine months, of which 54 (72%) were from the intervention group and 25 (66%) from the control group. In the final multivariate model, contact at three months (adjusted odds ratio - aOR = 6.15; 95% confidence interval - 95%CI: 2.16-17.51) and higher schooling level (≥ 12 years) (aOR = 3.26; 95%CI: 1.02-10.42) remained associated with the outcome, adjusted by race/skin color, age ≤ 35 years, and HIV serostatus disclosure. Future studies with TrTGW should include contact at regular intervals, with additional efforts aimed at participants with lower schooling level.
Travestis e mulheres trans (TrMT) pertencem aos grupos com mais alta prevalência do HIV no mundo, com maior probabilidade de infecção em relação à população geral e menor adesão a estratégias de prevenção e tratamento do que outros grupos vulneráveis. Considerando esses desafios, descrevemos os fatores associados à retenção de TrMT com HIV no projeto TransAmigas. O recrutamento ocorreu entre abril de 2018 e setembro de 2019, em um serviço público de saúde em São Paulo, Brasil. Foram inscritas 113 TrMT, atribuídas aleatoriamente para uma intervenção com navegadora de pares (75) ou um grupo controle (38) e seguidas durante nove meses. Para analisar a associação entre as variáveis selecionadas e o desfecho ("retenção aos nove meses" independentemente do contato aos três meses, definido pela "resposta completa ao questionário final"), foram empregados modelos de regressão logística bi e multivariados. Uma exploração qualitativa dos formulários de contato de pares foi realizada para validar e complementar a seleção prévia de variáveis do componente quantitativo. Das 113 participantes, 79 (69,9%) responderam à entrevista de nove meses, sendo 54 (72%) do grupo intervenção e 25 (66%) do grupo controle. No modelo multivariado final, o contato aos três meses (odds ratio ajustado - ORa = 6,15; intervalo de 95% de confiança - 95%CI: 2,16-17,51) e a maior escolaridade (≥ 12 anos) (ORa = 3,26; IC95%: 1,02-10,42) permaneceram associados ao desfecho, ajustados por raça/cor, idade < 35 anos e revelação do status sorológico para HIV. Pesquisas futuras com TrMT devem incluir contato em intervalos regulares, com esforços adicionais voltados a participantes com menor escolaridade.

Background: Often patients with chronic obstructive pulmonary disease (COPD) receive poor quality care with limited access to pulmonologists. We tested a novel intervention, INtegrating Care After Exacerbation of COPD (InCasE), that improved patient outcomes after hospitalization for COPD. InCasE used population-based identification of patients for proactive e-consultation by pulmonologists, and tailored recommendations with pre-populated orders timed to follow-up with primary care providers (PCPs). Although adoption by PCPs was high, we do not know how PCPs experienced the intervention. Objective: Our objective was to assess PCPs' experience with proactive pulmonary e-consults after hospitalization for COPD. Methods: We conducted a convergent mixed methods study among study PCPs at 2 medical centers and 10 outpatient clinics. PCPs underwent semi-structured interviews and surveys. We performed descriptive analyses on quantitative data and inductive and deductive coding based on prespecified themes of acceptability, appropriateness, and feasibility for qualitative data. Key Results: We conducted 10 interviews and 37 PCPs completed surveys. PCPs perceived InCasE to be acceptable and feasible. Facilitators included the proactive consult approach to patient identification and order entry. PCPs also noted the intervention was respectful and collegial. PCPs had concerns regarding appropriateness related to an unclear role in communicating recommendations to patients. PCPs also noted a potential decrease in autonomy if overused. Conclusion: This evaluation indicates that a proactive e-consult intervention can be deployed to collaboratively manage the health of populations with COPD in a way that is acceptable, appropriate, and feasible for primary care. Lessons learned from this study suggest the intervention may be transferable to other settings and specialties.
RESUMO
BACKGROUND: Cisgender men were mostly affected during the 2022 mpox multinational outbreak, with few cases reported in women. This study compares the characteristics of individuals diagnosed with mpox infection according to gender in Rio de Janeiro. METHODS: We obtained surveillance data of mpox cases notified to Rio de Janeiro State Health Department (June 12 to December 15, 2022). We compared women (cisgender or transgender) to men (cisgender or transgender) using chi-squared, Fisher's exact, and Mood's median tests. RESULTS: A total of 1306 mpox cases were reported; 1188 (91.0%) men (99.8% cisgender, 0.2% transgender), 108 (8.3%) women (87.0% cisgender, 13.0% transgender), and 10 (0.8%) non-binary persons. Compared to men, women were more frequently older (40+years: 34.3% vs. 25.1%; p < 0.001), reported more frequent non-sexual contact with a potential mpox case (21.4% vs. 9.8%; p = 0.004), fewer sexual partnerships (10.9 vs. 54.8%; p < 0.001), less sexual contact with a potential mpox case (18.5% vs. 43.0%; p < 0.001), fewer genital lesions (31.8% vs. 57.9%; p < 0.001), fewer systemic mpox signs/symptoms (38.0% vs. 50.1%; p = 0.015) and had a lower HIV prevalence (8.3% vs. 46.3%; p < 0.001), with all cases among transgender women. Eight women were hospitalized; no deaths occurred. The highest number of cases among women were notified in epidemiological week 34, when the number of cases among men started to decrease. CONCLUSIONS: Women diagnosed with mpox presented differences in epidemiological, behavioral, and clinical characteristics compared to men. Health services should provide a comprehensive assessment that accounts for gender diversity.

RESUMO
INTRODUCTION: Addictive use of the Internet among adolescents has been linked to a negative psychosocial development, but more detailed information about Internet addiction (IA) profiles is warranted. The aim of this study was to identify IA profiles in adolescents based on psychometric properties from the Internet Addiction test (IAT), and to assess the associations between the profiles and personal/social behaviors. MATERIAL AND METHODS: A cross-sectional study was performed at public schools from a Portuguese region, using a survey that included the IAT. We performed a latent profiling analysis to identify the profiles of adolescent based on the six IAT dimensions. RESULTS: From the 1915 responses, students' mean age was 15 ± 1.82 years, 53% were female. IA was found in 16.5%. Four models were estimated with latent profiling analysis. Analysis of the models by fit statistics, integrated completed likelihood and Lo-Mendell-Rubin likelihood ratio test, indicated a better solution with four profiles: Profile 1 - Worrisome lack of control users, Profile 2 - Balanced users, Profile 3 - Worrisome anticipation users, Profile 4 - Problematic users. CONCLUSION: This study provides a characterization of different patterns in adolescents' traits and behaviors associated with Internet addiction. Preventive approaches may be useful to reduce IA.
Introdução: A dependência da Internet em adolescentes tem sido associada a problemas no seu desenvolvimento psicossocial. Porém, a literatura carece de dados sobre diferentes perfis do uso de Internet. Este estudo pretendeu identificar perfis de dependência de Internet (DI), baseado nas características psicométricas do Internet Addiction test (IAT), verificando associações entre os perfis e comportamentos sociais. Material e Métodos: Estudo transversal realizado em escolas públicas de uma região Portuguesa mediante questionário que incluiu o IAT. Realizou-se uma análise de perfis latentes (APL) para identificar perfis de adolescentes, com base nos seis domínios do IAT. Resultados: Dos 1915 participantes, a idade média foi 15 ± 1,82 anos; 53% eram do sexo feminino. Identificou-se DI em 16,5%. A análise de modelos por qualidade de ajuste e rácio de verossimilhança de Lo-Mendell-Rubin revelou um modelo adequado com 4 perfis: 1 Utilizadores com dificuldade de controlo; 2 Utilizadores equilibrados; 3 Utilizadores com problemas de antecipação; 4 Utilizadores problemáticos. Conclusão: Este estudo permitiu a caracterização de diferentes padrões e comportamentos de adolescentes na DI, pelo que se alerta para uma abordagem preventiva na redução da DI.

Bonding to different dental restorative materials is challenging. This study aimed to evaluate the effect of a 10-MDP-based dentin adhesive on the shear bond strength (SBS) of self-adhesive resin cement (RC) to implant abutment materials. One hundred and twenty specimens were obtained from zirconia (ZO), cobalt-chromium alloy (CoCr), and commercially pure titanium (Ti), which were treated as follows (n = 10): control group-non-treated (CG), 10-MDP-based dentin adhesive (SB), light-cured SB (SB-LC), and zirconia primer (ZP). Blocks of RC were buildup and, after 24 h, were tested for bond strength. Data of SBS (MPa) were submitted to two-way ANOVA and Tukey test (α = 0.05). There was no difference in SBS among materials for CG and ZP, higher SBS were recorded for Ti SB and Ti SB-LC compared to ZO upon the same surface treatments. For the comparisons among treatments, SB-LC showed the highest SBS for CoCr. For ZO and Ti, higher SBS were recorded with SB and SB-LC. No cohesive failures were observed. It was concluded that the surface treatment with 10-MDP-based materials increased the bond strength of the resin cement to abutment materials, which showed to be material dependent.
