[PMID: 35810285 PMCID: PMC9271255 DOI: 10.1186/s12888-022-04095-8] [Citation(s) in RCA: 10] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/21/2022] [Accepted: 06/27/2022] [Indexed: 11/24/2022] Open
Abstract
BACKGROUND While suicide rates in high- and middle-income countries appeared stable in the early stages of the pandemic, we know little about within-country variations. We sought to investigate the impact of COVID-19 on suicide in Mexico's 32 states and to identify factors that may have contributed to observed variations between states. METHODS Interrupted time-series analysis to model the trend in monthly suicides before COVID-19 (from Jan 1, 2010, to March 31, 2020), comparing the expected number of suicides derived from the model with the observed number for the remainder of the year (April 1 to December 31, 2020) for each of Mexico's 32 states. Next, we modeled state-level trends using linear regression to study likely contributing factors at ecological level. RESULTS Suicide increased slightly across Mexico during the first nine months of the pandemic (RR 1.03; 95%CI 1.01-1.05). Suicides remained stable in 19 states, increase in seven states (RR range: 1.12-2.04) and a decrease in six states (RR range: 0.46-0.88). Suicide RR at the state level was positively associated with population density in 2020 and state level suicide death rate in 2019. CONCLUSIONS The COVID-19 pandemic had a differential effect on suicide death within the 32 states of Mexico. Higher population density and higher suicide rates in 2019 were associated with increased suicide. As the country struggles to cope with the ongoing pandemic, efforts to improve access to primary care and mental health care services (including suicide crisis intervention services) in these settings should be given priority.

Abstract
IntroductionPsilocybin is a naturally occurring plant alkaloid in mushrooms and a prodrug of psilocin. It is a serotonin receptor (5-HT2A) agonist and known psychedelic, with similar hallucinatory properties to lysergic acid diethylamide (LSD). It has been identified as a safe and effective option in treatment-resistant depression. Literature focus mainly on its use on depressive but its interest in other psychiatric disorders such as obsessive-compulsive disorder (OCD) has grown.ObjectivesTo review the clinical evidence for the use of hallucinogens such as psilocybin in OCD.MethodsNon-systematic review of literature found on PubMed/MEDLINE, Web of Science and Google Scholar, using the keywords “obsessive-compulsive disorder”, “psilocybin” and “hallucinogens”. Articles may include clinical trials, case report or case series. Articles found were admitted according to their relevance for the topic in review; only articles in English were included. Ongoing research trials on this topic were checked on ClinicalTrials.gov.ResultsSo far, only one open-label non-randomized study directly assessed the effects of psilocybin on OCD patients that found acute reductions of obsessive-compulsive symptoms. Case reports of patients improving with off-label use of psilocybin are reported. There are two ongoing phase I research trials, aiming to explore the effect of the substance on symptomatology, hypothesizing that psilocybin will normalize cerebral connectivity and thus correlate with clinical improvement.ConclusionsMore research to establish the usefulness of psilocybin in OCD patients is needed; the collected data is encouraging are there may be a role for its use on this disorder.

Abstract
AIMS To provide cross-national data for selected countries of the Americas on service utilization for psychiatric and substance use disorders, the distribution of these services among treatment sectors, treatment adequacy and factors associated with mental health treatment and adequacy of treatment. METHODS Data come from data collected from 6710 adults with 12 month mental disorder surveys across seven surveys in six countries in North (USA), Central (Mexico) and South (Argentina, Brazil, Colombia, Peru) America who were interviewed 2001-2015 as part of the World Health Organization (WHO) World Mental Health (WMH) Surveys. DSM-IV diagnoses were made with the WHO Composite International Diagnostic Interview (CIDI). Interviews also assessed service utilization by the treatment sector, adequacy of treatment received and socio-demographic correlates of treatment. RESULTS Little over one in four of respondents with any 12 month DSM-IV/CIDI disorder received any treatment. Although the vast majority (87.1%) of this treatment was minimally adequate, only 35.3% of cases received treatment that met acceptable quality guidelines. Indicators of social-advantage (high education and income) were associated with higher rates of service use and adequacy, but a number of other correlates varied across survey sites. CONCLUSIONS These results shed light on an enormous public health problem involving under-treatment of common mental disorders, although the problem is most extreme among people with social disadvantage. Promoting services that are more accessible, especially for those with few resources, is urgently needed.

Abstract
Abstract
BACKGROUND: Breast cancer (BC) in young women is uncommon and often more aggressive. There are disparities in terms of screening coverage, diagnostic features and access to optimal treatment among young BC patients worldwide. To better understand this scenario through real world data we performed a sub-analysis of AMAZONA III study. METHODS: The AMAZONA III study (GBECAM 0115) is a prospective registry that included 2950 women newly diagnosed with invasive BC in Brazil during the period of January 2016 to March 2018 within 22 sites. Of them, 2888 patients had valid data regarding age at diagnosis and complete baseline information. For the purpose of comparisons of epidemiologic and clinicopathologic features at the time of diagnosis of BC, patients were divided in two groups: women aged ≤40 years (Group 1) and >40 years (Group 2). Quantitative variables were expressed with mean, while categorical variables were described as their count and percentage and compared using the chi-square test. RESULTS: Of 2888 women, 486 (17%) were ≤40 years of age. No differences were found between ethnicity, performance status, body mass index, personal income, health insurance and family history of cancer between the two groups. Young women had higher educational level (p<0.001), were more involved into a labor activity (p<0.001) and were more frequently married (p<0.001). There were also significant differences regarding nulliparity (p<0.001) and previous use of oral contraceptives (p<0.001). Mode of detection of BC was symptomatic in 73.4% of young group versus 64.5% in older group and screen-detected was only 26.6% vs. 35.5% respectively (p<0.001). Table 1 describes clinicopathological characteristics of the two groups. Young women presented more frequently with stage III,T3/T4, Grade 3 tumors and HER-2 positive, Luminal B and triple negative subtypes. Women older than 40 years had more stage I, Luminal A and Grade 1/2 tumors. CONCLUSION: Brazilian women under the age of 40 have unfavorable clinicopathological features of BC at diagnosis with more aggressive subtypes and advanced stage compared with older women. No differences in socioeconomic and ethnical aspects were found but a higher percentage of young women had symptomatic detection of BC which could explain the later stage of disease at diagnosis. Young women were economically active and the majority married which highlights the socioeconomic impact of this disease in Brazil.

Abstract
Abstract
BACKGROUND
Breast cancer (BC) is the most common tumor in women in Brazil with about 60 thousand new cases estimated per year. In low and middle-income countries, patients with BC are diagnosed with more advanced stages as compared with high-income countries. In Brazil, disparities in access to new therapies are recognized; previous data suggests worse survival of BC patients treated in the public system. The aim of AMAZONA III study (GBECAM 0115) is to describe the current status of BC care in Brazil. Here we report patients data at baseline.
METHODS
The AMAZONA III is a prospective BC registry that included women 18 years or older with newly diagnosed stage I to IV BC from 22 sites in Brazil in the period of January 2016 to March 2018. All patients provided written informed consent; data was collected from interview and medical charts, comprising clinical-demographic variables, initial treatment and a planned follow-up for 5 years. BC subtypes were defined by hormone receptor (HR) expression, HER2 status and grade according to von Minckwitz G. et al 2012. Here we present a descriptive analysis of the patients' baseline characteristics. Continuous variables are shown as mean (standard-deviation) and categorical variables by its absolute and relative frequencies. The study is registered in clinicaltrials.gov NCT02663973.
RESULTS
A total of 2950 patients were included in the study. Median age at diagnosis was 53 years old (8.4% <= 35 years, 34.8% 36-50 years, 56.8% > 50 years), 58.6% were white, 34.4% had brown skin-color, 83% had children before BC diagnosis (median of 1 child/patient) and 63.1% had public health insurance. In terms of method of detection 34% were screen-detected whereas 66% were symptomatic, the last was even higher (70%) in patients in younger than 50 years. The distribution of BC stage at diagnosis was I (26.4%), II (41.6%), III (27%) and IV (5%). The most common histologies were ductal (80.9%) and lobular carcinoma (6.9%). The pathological characteristics were HR positive in 78.0%, HER-2 positive in 23.4% and grade 2 in 51%. BC subtypes were as follows: Luminal A 48%, Luminal B 12%, Luminal HER2 positive 17%, Non-luminal HER2 positive 7.3% and Triple negative 15.5%.
DISCUSSION
Breast cancer is diagnosed at an earlier age among Brazilian patients. The majority of patients were detected through symptomatic BC and therefore a significant proportion is still diagnosed in stages III and IV. Among other factors, these findings could have a significant impact in treatment outcomes. Further analysis of this large cohort of patients will help to identify other important elements and direct future strategies for breast cancer control.

Abstract
OBJECTIVES Religiosity is often associated with better health outcomes. The aim of the study was to examine associations between psychotic experiences (PEs) and religiosity in a large, cross-national sample. METHODS A total of 25 542 adult respondents across 18 countries from the WHO World Mental Health Surveys were assessed for PEs, religious affiliation and indices of religiosity, DSM-IV mental disorders and general medical conditions. Logistic regression models were used to estimate the association between PEs and religiosity with various adjustments. RESULTS Of 25 542 included respondents, 85.6% (SE = 0.3) (n = 21 860) respondents reported having a religious affiliation. Overall, there was no association between religious affiliation status and PEs. Within the subgroup having a religious affiliation, four of five indices of religiosity were significantly associated with increased odds of PEs (odds ratios ranged from 1.3 to 1.9). The findings persisted after adjustments for mental disorders and/or general medical conditions, as well as religious denomination type. There was a significant association between increased religiosity and reporting more types of PEs. CONCLUSIONS Among individuals with religious affiliations, those who reported more religiosity on four of five indices had increased odds of PEs. Focussed and more qualitative research will be required to unravel the interrelationship between religiosity and PEs.

Abstract
Abstract
Background
The incidence of brain metastases among women with metastatic breast cancer (MBC) ranges from 10 to 30% depending of breast cancer (BC) subtype. Inequities in the access to optimal treatment and shorter survival of BC by type of health care coverage were previously reported in an observational study in Brazil. The present analysis aims to analyze the impact of the type of health care coverage on survival outcomes of patients with MBC and brain involvement.
Methods
LACOG-0312 is a retrospective cohort study that enrolled patients with metastatic or locally advanced/recurrent unresectable BC diagnosed during 2012 in Brazil. Overall survival (OS) was defined as the time from the diagnosis of brain metastases and death from any cause. Comparisons were made using the Kaplan-Meier method based on the type of health care coverage (public vs. private) among patients who developed brain metastases. Cox regression analysis was performed for identification of independent prognostic factors associated with survival after brain metastases diagnosis.
Results
Among the 690 MBC patients included in the LACOG-0312 study, 145 (21%) were diagnosed with brain metastases. Of them, 94 (71,75%) were covered by the Brazilian public health care and 37 (28,25%) had private coverage. Baseline characteristics such as age at MBC diagnosis, stage IV at diagnosis and tumor subtypes were similar between both groups.
Median time to develop brain metastases after diagnosis of MBC was 14 months in the whole population with no differences between public and private patients (13 vs. 17 months p=0.172).
Median OS from the date of brain metastases diagnosis was similar for both groups: 10.0 months in private and 9.0 months in public health insured patients (HR 0.92 – 95%CI 0.55-1.51; p=0.729). In a multivariable analysis including type of health care coverage, only the triple negative BC subtype was associated with a worse survival post brain metastases diagnosis.
Conclusion
Our study indicates that health care coverage is not associated with survival outcomes in patients with MBC and brain metastases. Potential differences in the access to optimal care such as radiotherapy, surgery and systemic treatments may not play a significant role in the survival of theses patients possibly due to small clinical benefit of the current treatment options for brain metastases in breast cancer.

Abstract
Abstract
Background
Metastatic breast cancer (MBC) is an incurable disease in which latest therapies have evolving and improving patients survival. Inequities in the access to optimal treatment and shorter survival of BC by type of health care coverage were previously reported in an observational study in Brazil. In Brazil patients with private health coverage have access to the most recent therapies, however the public health system does not provide several therapies approved for the treatment of MBC such as everolimus, trastuzuman, eribulin, TDM-1, pertuzumab among others. The present analysis aims to analyze the impact of the type of health care coverage on survival outcomes of patients with MBC.
Methods
LACOG-0312 is a retrospective cohort study that enrolled patients with metastatic or locally advanced/recurrent unresectable BC diagnosed during 2012 in Brazil. Overall survival was defined as the time from the diagnosis of MBC and death from any cause. Comparisons were made using the Kaplan-Meier method based on the type of health care coverage (public vs. private). Cox regression analysis was performed for identification of independent prognostic factors associated with overall survival.
Results
A total of 634 patients with MBC were included in the study. Baseline characteristics by type of health care coverage was similar for visceral disease (43% in public and 44% in private, p=0.78), age at MBC diagnosis (median 62 years in public and 64 years in private, p=0.25), BC subtype (p=0.89), however more patients public insured were metastatic at diagnosis (42% vs. 33%) and had performance status >= 2 (12% vs. 3%).
The proportion of patients that received any first-line systemic therapy was similar in both groups (95.2% in public and 95.5% in private, p=1.0), however more patients with private insurance received second (82% vs. 71.6%, p=0.013) and third line (56% vs. 45%, p=0.024) therapy compared to public health covered patients.
OS from the date of MBC diagnosis in whole population was 36 months. There was no difference in terms of OS between private (42 months) and public (35 months) health insured patients (p=0.65). OS by BC subtype was 15 months for triple negative, 23 months in HER2 positive, 44 and 42 months for Luminal A and B respectively. There was no difference in OS by type of health insurance coverage in any BC subtypes.
In a multivariate analysis type of health care coverage did not associate with survival, only triple negative (HR (95% CI) – 3.495 (2.448 - 4.989); p <0.001), HER2 positive (HR (95% CI) - 2.287 (1.394 - 3.572); p = 0.001) BC subtypes and visceral metastases (HR (95% CI) – 1.413 (1.075 - 1.858); p <0.013) were correlated with a worse survival.
Conclusion
Our study suggestes that health care coverage is not associated with survival outcomes in patients with MBC. Potential differences in the access to optimal systemic treatments may not play a significant role in the survival of these patients. Real-world studies addressing the impact of new cancer therapies for different BC subtypes in MBC are needed.

Abstract
BACKGROUND Research on post-traumatic stress disorder (PTSD) course finds a substantial proportion of cases remit within 6 months, a majority within 2 years, and a substantial minority persists for many years. Results are inconsistent about pre-trauma predictors. METHODS The WHO World Mental Health surveys assessed lifetime DSM-IV PTSD presence-course after one randomly-selected trauma, allowing retrospective estimates of PTSD duration. Prior traumas, childhood adversities (CAs), and other lifetime DSM-IV mental disorders were examined as predictors using discrete-time person-month survival analysis among the 1575 respondents with lifetime PTSD. RESULTS 20%, 27%, and 50% of cases recovered within 3, 6, and 24 months and 77% within 10 years (the longest duration allowing stable estimates). Time-related recall bias was found largely for recoveries after 24 months. Recovery was weakly related to most trauma types other than very low [odds-ratio (OR) 0.2-0.3] early-recovery (within 24 months) associated with purposefully injuring/torturing/killing and witnessing atrocities and very low later-recovery (25+ months) associated with being kidnapped. The significant ORs for prior traumas, CAs, and mental disorders were generally inconsistent between early- and later-recovery models. Cross-validated versions of final models nonetheless discriminated significantly between the 50% of respondents with highest and lowest predicted probabilities of both early-recovery (66-55% v. 43%) and later-recovery (75-68% v. 39%). CONCLUSIONS We found PTSD recovery trajectories similar to those in previous studies. The weak associations of pre-trauma factors with recovery, also consistent with previous studies, presumably are due to stronger influences of post-trauma factors.

Abstract
Objective Different patterns of heavy drinking occur by country and proximity to the U.S. Mexico border. Few studies describe the impact of violence on drinking between countries and along the border. Methods Survey data is from U.S. Mexican origin adults living in Texas and Mexican border and non-border cities, N=4,796. Participants were asked about alcohol consumption, interpersonal physical violence (IPV) and exposure to community violence. Monthly hazardous drinking (5+/4+ for men/women) was the primary outcome. Multivariate logistic regression model comparisons identified best predictors. Results In the U.S. hazardous drinking was associated with past year IPV (ORadj=2.5; 1.8-3.5) and community violence (ORadj=1.4; 1.1-1.8). In Mexico, IPV (ORadj=3.9; 2.0-7.4) and border proximity (ORadj=0.5; 0.4-0.8) were associated with hazardous drinking but not community violence. Conclusion Hazardous drinking is associated with IPV in both countries, but violence did not explain border hazardous drinking differences where they existed in Mexico.

Abstract
Abstract
Background
Randomised clinical trials (RCT) are considered a gold standard generating efficacy and safety data supporting drug approval. However, real world data (RWD) reflecting health care delivery is becoming increasingly important. RWD on patient profiles and patterns of care in MBC are scarce in developing countries. As an example, observational studies suggest that despite guideline recommendations clearly indicating ET for hormone receptor positive MBC, a considerable proportion of patients in clinical practice begin chemotherapy in early lines of therapy. This pragmatic information addresses the uptake and applicability of the RCT results and should be able to help informing health care planning complementing RCT generated data. The objective of this study is to describe patient characteristics and evaluate actual physician-reported treatments for MBC in Brazil.
Methods
This analysis addresses the first 362 patients included in LACOG-0312, a retrospective study planning to recruit over 700 patients (cut-off date April 30th 2016) with recurrent locally advanced or MBC diagnosed in 2012 in 18 institutions across Brazil. Patient characteristics, type of health insurance coverage, treatment and survival outcome were analysed.
Results
Median age at BC diagnosis was 53 years and 37% were premenopausal. Regarding the educational level, 63.2% had completed elementary (primary) schooling, 75.7% were covered by the public health system while 24.3% had some form of private coverage. 70% of patients had hormone receptor positive (HR+) and 18% had HER2 positive tumors. Median disease free survival time from surgery was 29 months. Interestingly, 30% of patients underwent a biopsy of a metastatic site. Of the 362 patients, 349 (96.9%) received some form of palliative systemic therapy. Median time from diagnosis of metastatic disease to first-line therapy initiation was 46 days but a significant difference was noted between patients with public versus private health insurance (50 vs. 33 days p=0.012). Half of the patients received at least 3 lines of therapy (chemo or endocrine) to a maximum of 9 lines. In patients with HR+ tumors, endocrine therapy was administered in 47% in first, 65% in second and 61% in third-line, respectively. Median overall survival (OS) from diagnosis of metastatic disease was 34 months (CI 95%: 25.7-44.3) and no differences in OS were observed between patients with public or private coverage (34 months vs. 35 months p=0.808). Causes of death were cancer in 85.2% of patients and treatment toxicity in 3.6%.
Conclusion
Our study included a population with predominantly low educational level and mostly public health insurance. This likely corresponds to the majority of cases and reflects cancer care patterns in Brazil and many developing countries. A considerable proportion of patients were premenopausal at MBC diagnosis. More than half of HR+ patients received at least 3 lines of endocrine therapy although 54% of them had chemotherapy as the first systemic treatment. Patients from the public health system experienced a delay in starting first-line therapy but this didn't seem to jeopardize cancer outcomes in this setting.

Abstract
IntroductionWithin psychiatry, sexology is a very particular area of expertise both by the nature and specificity of its diagnosis, as by the various difficulties and challenges their patients place. Sexology is a sub-specialty niche, but also a vast universe that covers such diverse conditions as paraphilia, gender dysphoria or sexual dysfunction. The sexology consultation of Santa Maria Hospital (HSM) is one of the biggest centers specialized in sexual disorders in the country. Consultations depend on the collaboration of a sexologist psychiatrist and psychiatry residents in close connection with endocrinology, urology and plastic surgery services.ObjectiveWe intend to conduct a characterization of the population observed in the HSM sexology consultation, in a period of 2 years, from the analyses of different general and diagnosis-specific relevant variables.MethodsWe intent to make a descriptive analysis of the population that attended the sexology consultation over the last 2 years. The sample study refers to all patients who have been specifically referred to sexology department or that directly requested access to this consultation. Data will be collected from medical computer records.ResultsThrough systematic evaluation of different variables we can possibly conclude by some putative associations. A comprehensive characterization of this particular population is a possible method for a better and deeper insight on the diagnosis itself.ConclusionsThe purpose of this work is to increase peers’ sensitivity both to sexology and to the patients sexology serves.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
IntroductionExhibitionistic disorder may be present when there is sexual arousal from the exposure of one's genitals to an unsuspecting and nonconsenting person. This disorder prevalence is unknown but we know it is highly unusual in females. It generally starts at adolescence and its course is likely to vary with age. There are temperamental and environmental risk factors.Most of what we know about exhibitionistic disorder is largely based on research with individuals convicted for criminal acts involving genital exposure, and this may represent an important bias. From a clinical case of exhibitionism, the authors intend to review this type of paraphilia from an historical, conceptual and etiologic point of view.ObjectiveTo review the concept behind this diagnosis and its evolution, the comprehensive theories that attempt to justify and frame it, as well as the type of intervention currently considered to be the state of the art.MethodsPatient's observation and assessment, along with an extensive review of the relevant literature.ConclusionsStarting from a real clinical case, the authors present a general theoretical review on the subject.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
BACKGROUND To examine barriers to initiation and continuation of mental health treatment among individuals with common mental disorders. METHOD Data were from the World Health Organization (WHO) World Mental Health (WMH) surveys. Representative household samples were interviewed face to face in 24 countries. Reasons to initiate and continue treatment were examined in a subsample (n = 63,678) and analyzed at different levels of clinical severity. RESULTS Among those with a DSM-IV disorder in the past 12 months, low perceived need was the most common reason for not initiating treatment and more common among moderate and mild than severe cases. Women and younger people with disorders were more likely to recognize a need for treatment. A desire to handle the problem on one's own was the most common barrier among respondents with a disorder who perceived a need for treatment (63.8%). Attitudinal barriers were much more important than structural barriers to both initiating and continuing treatment. However, attitudinal barriers dominated for mild-moderate cases and structural barriers for severe cases. Perceived ineffectiveness of treatment was the most commonly reported reason for treatment drop-out (39.3%), followed by negative experiences with treatment providers (26.9% of respondents with severe disorders). CONCLUSIONS Low perceived need and attitudinal barriers are the major barriers to seeking and staying in treatment among individuals with common mental disorders worldwide. Apart from targeting structural barriers, mainly in countries with poor resources, increasing population mental health literacy is an important endeavor worldwide.

Abstract
BACKGROUND Suicide is the 11th leading cause of death in the USA. Suicide rates vary across ethnic groups. Whether suicide behavior differs by ethnic groups in the USA in the same way as observed for suicide death is a matter of current discussion. The aim of this report was to compare the lifetime prevalence of suicide ideation and attempt among four main ethnic groups (Asians, Blacks, Hispanics, and Whites) in the USA. METHOD Suicide ideation and attempts were assessed using the World Mental Health version of the Composite International Diagnostic Interview (WMH-CIDI). Discrete time survival analysis was used to examine risk for lifetime suicidality by ethnicity and immigration among 15 180 participants in the Collaborative Psychiatric Epidemiological Surveys (CPES), a group of cross-sectional surveys. RESULTS Suicide ideation was most common among Non-Hispanic Whites (16.10%), least common among Asians (9.02%) and intermediate among Hispanics (11.35%) and Non-Hispanic Blacks (11.82%). Suicide attempts were equally common among Non-Hispanic Whites (4.69%), Hispanics (5.11%) and Non-Hispanic Blacks (4.15%) and less common among Asians (2.55%). These differences in the crude prevalence rates of suicide ideation decreased but persisted after control for psychiatric disorders, but disappeared for suicide attempt. Within ethnic groups, risk for suicidality was low among immigrants prior to migration compared to the US born, but equalized over time after migration. CONCLUSIONS Ethnic differences in suicidal behaviors are explained partly by differences in psychiatric disorders and low risk prior to arrival in the USA. These differences are likely to decrease as the US-born proportion of Hispanics and Asians increases.

Abstract
Abstract
Background: Breast cancer is the most common type of cancer among Brazilian women with almost 50.000 new cases per year. There are few data regarding the clinical presentation, treatment and specially outcome of this population. Brazilian health system is composed by Public institutions (Pu); Private centers (Pr) and some institutions that assist both Public and Private patients (PuPr).
Material and Methods: We collected data from 17 cancer centers distributed throughout Brazil among Pu; Pr and PuPr centers. We've analyzed data from 1-clinical characteristics, 2- pathologic characteristics and 3-type of treatment received among 2435 patients from May 2008 to May 2009.
Results: Mean age at diagnosis was 53 years, with about 30% below age 50. Most of the cases were Invasive Ductal Cancer (83%). Stage 0 was seen in 3.2%, Stage I in 21,8%, Stage II in 46,6%, Stage 3 in 24,6% and Stage IV in 3,9 %. Clinical Stage III + IV was seen in 18,5% of the Pu institutions, only 3,7% of the Pr ones and about 6,2% among those PuPr. Hormone receptors were positive in 55%. Her-2 was overexpressed in 27,3% of the patients, and triple negative were seen in 11,6%. Most of the patients were submitted to surgery (92,9%). In Pu institutions only 36% of the patients were submitted to Breast Conserving Surgery (BCS) and in the Pr institutions 49,4% of the patients were submitted to BCS and in the PuPr 47%. Breast reconstruction was made in 15,8% and did not differ between Pu and Pr institutions. Sentinel node biopsy was done in 30,6% of the patients (26,8% of the patients from the Pr institutions and 26,8% of the Pu ones and 33% among PuPr). Neoadjuvant treatment was done in 21,5% of the patients (Pu=27,2%; Pr=13,9% and PuPr 13,2%). Most of this neoadjuvant treatment was chemotherapy (93,8%) and only 4,3% was hormonetherapy (HT). 30% of the patients received AC, 41% A+taxane and 18,9% FAC/FEC. Besides we have almost 30% of Her-2 overexpressed only 1,1% of the patients received trastuzumab in the neoadjuvant setting. Tamoxifen was used in 48,3% when neoadjuvant HT was done, and aromatase inhibitor (AI) was used in 34,5%. Most of the patients received any kind of adjuvant treatment (89,2%). Chemotherapy was done in 76,6% and hormonetherapy in 69,8%. When chemotherapy was used the preference regiment was FAC/FEC (27,3%), followed by CMF (17,5%) and AC (11,9%). Trastuzumab was use in only 5,8% of the patients (Pu=6,8%, Pr=18,3% and PuPr 3% among all patients that received chemotherapy). In the adjuvant setting, Tamoxifen (TAM) was prescribed in 69,8% of the cases (Pu=87,6%, Pr=79,6% and PuPr 78,8%), AI in 8,2% (Pu=5,9%, Pr=9,3% and PuPr 13,8%), and sequential TAM/AI in 6,6% (Pu=6,1%, Pr=8,3% and PuPr 6,4%). About 17% of the patients had metastasis.
Conclusions: There are important differences between the public and private institutions in Brazil, the patients from the Pu institutions were five times more likely to be diagnosed in stage III or IV, they usually receive neoadjuvant treatment, and when surgery was done, most of them were treated with radical procedures. Besides the overexpression of Her-2 (30%) a minority of the patients received treatment with trastuzumab even for the Private centers (high cost for a developing country).

Abstract
SUMMARY
In vitro studies to assess bond strength between resins and ceramics have used surfaces that have been ground flat to ensure standardization; however, in patients, ceramic surfaces are irregular. The effect of a polished and unpolished ceramic on bond strength needs to be investigated. Sixty ceramic specimens (20×5×2 mm) were made and divided into two groups. One group was ground with 220- to 2000-grit wet silicon carbide paper and polished with 3-, 1-, and ¼-μm diamond paste; the other group was neither ground nor polished. Each group was divided into three subgroups: treated polished controls (PC) and untreated unpolished controls (UPC), polished (PE) and unpolished specimens (UPE) etched with hydrofluoric acid, and polished (PS) and unpolished specimens (UPS) sandblasted with alumina. Resin cement cylinders were built over each specimen. Shear bond strength was measured, and the fractured site was analyzed. Analysis of variance (ANOVA) and Tukey post hoc tests were performed. PE (44.47 ± 5.91 MPa) and UPE (39.70 ± 5.46 MPa) had the highest mean bond strength. PS (31.05 ± 8.81 MPa), UPC (29.11 ± 8.11 MPa), and UPS (26.41 ± 7.31 MPa) were statistically similar, and PC (24.96 ± 8.17 MPa) was the lowest. Hydrofluoric acid provides the highest bond strength regardless of whether the surface is polished or not.
