Human health risks associated to trace elements and metals in commercial fish from the Brazilian Amazon.

Fish constitutes the main protein source for the Amazonian population. However, the impact of different anthropogenic activities on trace element and metal accumulation in fish and their risks for human health at a regional scale remain largely unexplored. Here we assessed exposure levels of 10 trace elements and metals (Cr, Mn, Fe, Ni, Cu, Zn, As, Cd, Pb, and Hg) in 56 samples belonging to 11 different species of fish from the Brazilian Amazon. We studied the relationship between exposure levels, fish origin, and fish feeding habits, and assessed toxicological and carcinogenic risks for the Amazonian population. No significant correlation was found between sampling site and exposure levels to the studied elements, but a significant difference was found between the accumulation of some metals and the position of the fish species in the food chain. The concentrations of Cr and Hg in fish flesh were found to exceed the Brazilian limits for human consumption. This study shows that current fish consumption patterns can lead to estimated daily intakes of Hg, As and Cr that exceed the oral reference dose, thus posing a toxicological concern. Furthermore, carcinogenic risks may be expected due to the continued exposure to Cr and As. The results of this study show that the consumption of wild caught fish in the Amazon region should be controlled. Moreover, continued monitoring of trace element and metal contamination in fish and on the health of the Amazonian population is recommended, particularly for riverine and indigenous communities.

Fish mortality in the Amazonian drought of 2023: the role of experimental biology in our response to climate change.

Higher temperatures exacerbate drought conditions by increasing evaporation rates, reducing soil moisture and altering precipitation patterns. As global temperatures rise as a result of climate change, these effects intensify, leading to more frequent and severe droughts. This link between higher temperatures and drought is particularly evident in sensitive ecosystems like the Amazon rainforest, where reduced rainfall and higher evaporation rates result in significantly lower water levels, threatening biodiversity and human livelihoods. As an example, the serious drought experienced in the Amazon basin in 2023 resulted in a significant decline in fish populations. Elevated water temperatures, reaching up to 38°C, led to mass mortality events, because these temperatures surpass the thermal tolerance of many Amazonian fish species. We know this because our group has collected data on critical thermal maxima (CTmax) for various fish species over multiple years. Additionally, warmer waters can cause hypoxia, further exacerbating fish mortality. Thus, even Amazon fish species, which have relatively high thermal tolerance, are being impacted by climate change. The Amazon drought experienced in 2023 underscores the urgent need for climate action to mitigate the devastating effects on Amazonian biodiversity. The fact that we have been able to link fish mortality events to data on the thermal tolerance of fishes emphasizes the important role of experimental biology in elucidating the mechanisms behind these events, a link that we aim to highlight in this Perspective.

Amazonian rivers are leaky barriers to gene flow in forest understory birds.

Ever since Alfred Russel Wallace's nineteenth-century observation that related terrestrial species are often separated on opposing riverbanks, major Amazonian rivers have been recognized as key drivers of speciation. However, rivers are dynamic entities whose widths and courses may vary through time. It thus remains unknown how effective rivers are at reducing gene flow and promoting speciation over long timescales. We fit demographic models to genomic sequences to reconstruct the history of gene flow in three pairs of avian taxa fully separated by different Amazonian rivers, and whose geographic ranges do not make contact in headwater regions where rivers may cease to be barriers. Models with gene flow were best fit but still supported an initial period without any gene flow, which ranged from 187 000 to over 959 000 years, suggesting that rivers are capable of initiating speciation through long stretches of allopatric divergence. Allopatry was followed by either bursts or prolonged episodes of gene flow that retarded genomic differentiation but did not fully homogenize populations. Our results support Amazonian rivers as key barriers that promoted speciation and the build-up of species richness, but they also suggest that river barriers are often leaky, with genomic divergence accumulating slowly owing to episodes of substantial gene flow.

A Cluster of Diutina catenulata Funguria in Patients with Coronavirus Disease 2019 (COVID-19) Hospitalized in a Tertiary Reference Hospital from Rio de Janeiro, Brazil.

During the COVID-19 pandemic, fungal infections, especially pulmonary aspergillosis, mucormycosis, and invasive candidiasis, have emerged as a significant health concern. Beyond Candida albicans, the most common cause of invasive candidiasis, other rare ascomycetous yeast species have been described in tertiary care units, potentially posing a broader health threat. We have isolated, from September 2020 to June 2021, nine Diutina catenulata strains from urine samples of six patients. This was intriguing as this fungus had not been previously identified in our institution, nor after June 2021. Therefore, we decided to outline the clinical features of the patients with this rare pathogen, to describe phenotypic characteristics, including antifungal susceptibility profiles, of this yeast species and to identify the genetic makeup through whole-genome sequencing analysis to evaluate if this was a cluster of genetically similar D. catenulata isolates in our institution. The strains were identified through MALDI-TOF MS analyses and Sanger sequencing of two rDNA regions. All patients yielding D. catenulata from urine samples needed ventilator support and used urinary catheters during hospitalization for treatment of COVID-19. None of them had received COVID-19 vaccines. Morphological and biochemical profiles of the nine strains were largely consistent, although fluconazole susceptibility varied, ranging from 4 to 32 µg/mL. Phylogenomic analysis revealed minimal genetic variation among the isolates, with low intrapopulation variation, supported by the identification of only 84 SNPs across all strains. Therefore, we propose that the yeast strains isolated were part of a cluster of D. catenulata funguria in the context of COVID-19.

Spatial distribution of the sport fishing in the state of Amazonas, northern Brazil.

The objective of this study was to spatialize sport fishing operations and assess the frequency of the use of the fishing areas in the state of Amazonas by combining the Geographic Information System (GIS) approach and information available in the documents sent to the Instituto de Proteção Ambiental do Amazonas (IPAAM). Information on sport fishing tourism operations was gathered from the IPAAM database and fishing licenses (FLs). Data analysis was conducted utilizing descriptive analysis, and the spatialization of the locations was performed using Q-GIS software. From 2002 to August 2021, 163 requests for FLs were made. There was a decrease in the amount of first time FL requests, with a peak in 2018 and 2019, N=17 and N=18, respectively. The activity is conducted in 24 municipalities, with Barcelos (31.36%) and Presidente Figueiredo (17.75%) being the most popular. At the sub-basin level, sport fishing is notably present in the Negro, Amazonas, Aripuanã, Madeira, Purus and Solimões River basins. Overall, 26.38% of operations take place in conservation areas, specifically in sustainable development reserves (SDRs). Barcelos recorded the largest number of rivers used, with 15 rivers. These results can support future proposals for the sustainable management of fisheries through the zoning of fishing areas in the state of Amazonas.

LATENT TUBERCULOSIS IN PATIENTS WITH CROHN'S DISEASE IN A UNIVERSITY HOSPITAL IN NORTHEASTERN BRAZIL: A RETROSPECTIVE STUDY.

BACKGROUND: Among chronic condition problems, tuberculosis still represents a serious public health problem globally. OBJECTIVE: To investigate latent tuberculosis infection in patients with Crohn's disease. Retrospective, descriptive cross-sectional study of quantitative analysis. METHODS: The research was conducted on diagnosed cases of Crohn's disease at the University Hospital located in a city in Northeastern Brazil. All cases of patients with Crohn's disease undergoing isoniazid or rifampicin therapy for latent tuberculosis (LTBI) were included in the study. The data obtained were subsequently subjected to statistical analysis using the Statistical Package for the Social Sciences (SPSS) program. RESULTS: We analyzed 235 medical records, and it was observed that 56% were male, with a mean age of 42.7. Among these, 54% declared themselves as brown, 31% had completed high school, and 47% were residents of the city of Teresina. Regarding the clinical and epidemiological characteristics of the studied patients classified as having ILTB, 34% of the medical records were diagnosed by tuberculin test, 48.51% were investigated by x-ray examination, and the recent location affected the colon with 27%. CONCLUSION: Overall, the health profile of the participants in this study aligns with findings previously established in the literature, particularly studies conducted in other Brazilian states, as well as in other developing countries.

Income and education level trajectories and changes in the daily consumption of vegetables after thirteen years of follow-up: the Pró-Saúde Study.

OBJECTIVE: This study aimed to examine whether education level and income trajectories influence vegetable consumption changes over 13 years among civil servants at different campuses of a university in the state of Rio de Janeiro, Brazil. METHODS: Vegetable intake frequency (daily and non-daily consumption), income (per capita), and education level (maintenance of low schooling/ upward mobility/maintenance of high schooling) were assessed at baseline (1999) and in the fourth wave (2011-12) of the Pró-Saúde (Pro-Health) cohort study. A total of 2,381 participants were analyzed. The association between educational and income trajectories and variation in vegetable consumption was assessed via crude and age-adjusted generalized linear models, stratified by sex. RESULTS: Men in upward educational mobility showed a 0.5% increase in vegetable consumption (p=0.01), while women in this group demonstrated a 2.5% increase (p=0.05). Adjusted models showed that women who reduced their income had a lower likelihood of consuming vegetables (odds ratio [OR] 0.93; 95% confidence interval [CI] 0.89-0.97). CONCLUSIONS: The findings highlight the influence of social inequalities on vegetable consumption in adults.

Current status of laparoscopy teaching in gynecology and obstetrics medical residency in Brazil.

OBJECTIVE: To characterize laparoscopy teaching in Medical Residency Programs in Gynecology and Obstetrics in Brazil, and to evaluate preceptors' characteristics in laparoscopy programs and map laparoscopic training practice scenarios. METHODS: This descriptive cross-sectional study evaluated questionnaire responses from coordinators of the Medical Residency Programs in Gynecology and Obstetrics from 2019 to 2021. RESULTS: The questionnaire was sent to 175 programs, and 90 responses were received (51.4%). From the 85 valid responses, it was noted that 67 programs had laparoscopic training. Of the 64 responses received regarding location, 32 replies (50%) indicated the Southeast of Brazil, particularly some country's capitals. In 37.3% (n=25) of the cases, the program coordinator performed laparoscopy. The chief of the laparoscopy sector has advanced experience in most 52.5% (n=10) medical residency services; the preceptors also had advanced experience in 89.4% (n=59) of the services. Residents received laboratory training in 39.4% (n=26) of the services. In most cases, training was performed using a physical simulator. Of the 26 medical residency services with laparoscopy training outside the operating room, 80.8% (n=21) performed them as part of the curriculum, 61.5% (n=16) had a schedule for the same, and only 3.9% (n=1) were objectively evaluated. CONCLUSION: Laparoscopy teaching in Brazil is heterogeneous, with only a few programs offering any training in laparoscopy. The preceptors had advanced experience and participated in laboratory and operating room training. Only a few programs have their own laboratories or training centers, and most teaching programs do not plan to set up training centers.

Prevalence and risk factors of Burnout syndrome among intensive care unit members during the second wave of COVID-19: a single-center study.

OBJECTIVE: To evaluate the prevalence of burnout among the intensive care unit team of a university hospital after the second wave of COVID-19 and identify the key factors associated with its development. METHODS: This single-center study included 395 employees from a multidisciplinary team. The participants completed a questionnaire based on the Maslach Burnout Inventory. Multivariate analysis was used to identify the factors associated with burnout. RESULTS: Of 395 participants, 220 responded to the questionnaire (response rate: 56%). The prevalence of Burnout syndrome, defined as a severe score in at least one dimension, was 64.5% (142/220). Emotional distress was the most prevalent dimension, with a severe score affecting 50.5% (111/220) of the participants, followed by depersonalization at 39.1% (86/220). Only 5.9% (13/220) had severe scores in all three dimensions. Multivariate analysis revealed that being a physician was significantly associated with severe burnout symptoms in at least one dimension (odds ratio (OR), 1.32; 95% confidence interval (95%CI): 1.57-9.05; p=0.003). Additionally, having two or more jobs was associated with burnout in the three dimensions (OR=1.65; 95%CI=1.39-19.59; p=0.01). CONCLUSION: This study highlights the alarming prevalence of burnout among intensive care unit teams, particularly among physicians, following the second wave of COVID-19. This emphasizes the need for targeted interventions and support systems to mitigate burnout and reduce its negative impact on healthcare professionals' well-being and patient care.

Association between participation restriction due to hearing loss and self-perception of health, social support, and quality of life in elderly people: a cross-sectional study. / Associação entre restrição à participação decorrente de perda auditiva e autopercepção de saúde, suporte social e qualidade de vida da pessoa idosa: estudo transversal.

PURPOSE: To verify the association between participation restriction due to hearing loss and self-perception of health, social support, and quality of life in elderly people. METHODS: This is a cross-sectional, observational, and descriptive study with a quantitative data approach. A database with information collected in a medium-sized Brazilian municipality was used. The study was conducted with 235 elderly people registered in five Family Health Strategy Units. Sociodemographic and health information and the results of the following questionnaires were used: Hearing Handicap Inventory for the Elderly - Screening Version (HHIE-S), Medical Outcomes Study (MOS) Social Support Survey, Subjective Health Assessment, and Short-Form 6-Dimension (SF-6D) Health and Quality of Life Index. Groups with and without participation restriction were compared according to sociodemographic, health, social support, and quality of life variables. A multivariate binary logistic regression method was employed to evaluate the associations between the independent variables and participation restriction. RESULTS: The group with participation restriction is composed of older individuals with lower quality of life and poorer self-perception of health. Poorer self-perception of health was the only predictor of participation restriction related to hearing loss. CONCLUSION: Participation restriction is associated with poorer self-perception of health. The study highlights the importance of assessing individuals' self-perception regarding biopsychosocial issues, in addition to considering the environmental context to understand the social and emotional impacts caused by hearing loss.

OBJETIVO: Verificar a associação entre a restrição à participação decorrente de perda auditiva e a autopercepção da saúde, do suporte social e da qualidade de vida em pessoas idosas. MÉTODO: Estudo com delineamento transversal, observacional, descritivo e com abordagem quantitativa dos dados. Foi utilizado um banco de dados com informações coletadas em um município brasileiro de médio porte, sendo incluídas no estudo 235 pessoas cadastradas em cinco unidades de Estratégia de Saúde da Família. Utilizou-se informações sociodemográficas, de saúde e os resultados dos questionários: avaliação à restrição à participação (Hearing Handicap Inventory for the Elderly Screening Version - HHIE-S), Suporte Social (Escala de Apoio Social do MOS), Avaliação Subjetiva de Saúde e a Qualidade de Vida (Short-Form 6 dimensions- SF-6D). Comparou-se os grupos com restrição e sem restrição à participação segundo as variáveis sociodemográficas, de saúde, suporte social e qualidade de vida. Um método de regressão logística binária multivariado foi utilizado para avaliar as associações entre as variáveis independentes e a restrição à participação. RESULTADOS: O grupo com restrição à participação é mais velho, possui menor qualidade de vida e pior autopercepção de saúde. Esta se mostrou ser o único preditor da restrição à participação relacionada à perda auditiva. CONCLUSÃO: A restrição à participação está associada a uma pior autopercepção de saúde. O estudo revela a importância de avaliar a autopercepção dos indivíduos quanto às questões biopsicossociais, além de considerar o contexto ambiental para a compreensão dos impactos sociais e emocionais da perda auditiva.

Profile of individuals served and presumed coverage of Psychosocial Care Centers (CAPS) in Brazil: A study of the period 2013-2019.

OBJECTIVE: To describe the profile of individuals with depression who received assistance at CAPS in Brazil between 2013 and 2019, focusing on their clinical and demographic characteristics, and to calculate the estimated coverage of CAPS across the national territory and its constituent federal units. METHODS: Descriptive, ecological, time-series study with secondary data from national databases, referring to care provided at CAPS in the country for adults aged 18 years or over-diagnosed with depression (F32-32.9 and F33-F33.9). The estimated coverage of CAPS was calculated for 2013 and 2019 using registered and active services. RESULTS: There was a 107% increase in the number of patients with depression receiving treatment at CAPS between 2013 and 2019. Women accounted for 77% of the patients, with the majority falling within the age range of 41 to 61years (49%). The predominant racial demographics were white (38%) and brown (34%). The diagnosis of depressive episodes was prevalent among 65% of the patients, and individual care was administrated to 75% of them. The presumed CAPS coverage was 71% in 2013 and increased to 87% in 2019 nationwide, although significant discrepancies were observed among different states. CONCLUSION: Progress was evident in the implementation of CAPS across Brazil during the period spanning 2013 to 2019. Nonetheless, disparities persist among the federative units, and there remains an underutilization of group and family care within CAPS services.

Score of fear of COVID-19 and physical activity level are related to the habitual consumption of dietary supplements.

The measures implemented to contain the COVID-19 pandemic resulted in both behavioral and lifestyle changes. The "Changes in Lifestyle-Related Behavior" instrument was developed to assess lifestyle-related behaviors in the Indian population. However, considering current knowledge, this instrument was not adapted for the Brazilian population. In addition, the relationship between fear of COVID-19 and consumption of dietary supplements has not yet been evaluated. Thus, we aimed to investigate the relationship between the use of dietary supplements with lifestyle behavior and the fear of COVID-19, as well as assess the psychometric properties of the Brazilian version of the "Changes in Lifestyle-Related Behavior" instrument. An online questionnaire assessed sociodemographic, occupational, anthropometric, physical activity (International Physical Activity Questionnaire-short form), fear of COVID-19, and lifestyle behavior data from 416 Brazilian adults (237 females; 18-60y). Mann-Whitney, Chi-square test, exploratory, and confirmatory analyses were applied. Exploratory and confirmatory analyses showed a satisfactory adequacy level of the questionnaire (CMIN/DF = 2.689; Cronbach's α = 0.60) with 5 domains ('Bad eating behavior'; 'Healthy eating'; 'Sleep quality'; 'Interest in cooking'; 'Number of portions and meals'). Lower fear of COVID-19 scores and higher levels of physical activity were found in participants who reported previous dietary supplement intake during the pandemic; in addition, the group that did not ingest dietary supplements reported greater changes in stress and anxiety levels during the pandemic (p<0.05). The intake of dietary supplements before the pandemic was associated with greater energy expenditure and better coping with the fear of COVID-19 during the pandemic. Additionally, the Changes in Lifestyle-Related Behavior tool can be used to assess lifestyle-related variables during the pandemic.

Survival Analysis in Adult Heart Transplantation: Experience from a Brazilian Single Center.

INTRODUCTION: Heart transplantation is the gold standard for advanced heart failure treatment. This study examines the survival rates and risk factors for early mortality in adult heart transplant recipients at a Brazilian center. METHODS: This retrospective cohort study involved 255 adult heart transplant patients from a single center in Brazil. Data were collected from medical records and databases including three defined periods (2012-2015, 2016-2019, and 2020-2022). Statistical analysis employed Kaplan-Meier survival curves, Cox proportional hazards analysis for 30-day mortality risk factors, and Log-rank tests. RESULTS: The recipients were mostly male (74.9%), and the mean age was 46.6 years. Main causes of heart failure were idiopathic dilated cardiomyopathy (33.9%), Chagas cardiomyopathy (18%), and ischemic cardiomyopathy (14.3%). The study revealed an overall survival of 68.1% at one year, 58% at five years, and 40.8% at 10 years after heart transplantation. Survivalimproved significantly over time, combining the most recent periods (2016 to 2022) it was 73.2% in the first year and 63% in five years. The main risk factors for 30-day mortality were longer time on cardiopulmonary bypass, the initial period of transplants (2012 to 2015), older age of the donor, and nutritional status of the donor (overweight or obese). The main causes of death within 30 days post-transplant were infection and primary graft dysfunction. CONCLUSION: The survival analysis by period demonstrated that the increased surgical volume, coupled with the team's experience and modifications to the immunosuppression protocol, contributed to the improved early and mid-term outcomes.

Assessment of EuroSCORE II and STS Score Performance and the Impact of Surgical Urgency in Isolated Coronary Artery Bypass Graft Surgery at a Referral Center in São Paulo, Brazil.

INTRODUCTION: Risk prediction models, such as The Society of Thoracic Surgeons (STS) risk score and the European System for Cardiac Operative Risk Evaluation II (EuroSCORE II), are recommended for assessing operative mortality in coronary artery bypass grafting (CABG). However, their performance is questionable in Brazil. OBJECTIVE: To assess the performance of the STS score and EuroSCORE II in isolated CABG at a Brazilian reference center. METHODS: Observationaland prospective study including 438 patients undergoing isolated CABG from May 2022-May 2023 at the Instituto Dante Pazzanese de Cardiologia. Observed mortality was compared with predicted mortality (STS score and EuroSCORE II) by discrimination (area under the curve [AUC]) and calibration (observed/expected ratio [O/E]) in the total sample and subgroups of stable coronary artery disease (CAD) and acute coronary syndrome (ACS). RESULTS: Observed mortality was 4.3% (n=19) and estimated at 1.21% and 2.74% by STS and EuroSCORE II, respectively. STS (AUC=0.646; 95% confidence interva [CI] 0.760-0.532) and EuroSCORE II (AUC=0.697; 95% CI 0.802-0.593) presented poor discrimination. Calibration was absent for the North American mode (P<0.05) and reasonable for the European model (O/E=1.59, P=0.056). In the subgroups, EuroSCORE II had AUC of 0.616 (95% CI 0.752-0.480) and 0.826 (95% CI 0.991-0.661), while STS had AUC of 0.467 (95% CI 0.622-0.312) and 0.855 (95% CI 1.0-0.706) in ACS and CAD patients, respectively, demonstrating good score performance in stable patients. CONCLUSION: The predictive models did not perform optimally in the total sample, but the EuroSCORE was superior, especially in elective stable patients, where accuracy was satisfactory.

Transition from opportunistic cytological to organized screening program with DNA-HPV testing detected prevalent cervical cancers 10 years in advance.

Cervical cancer screening in Brazil is opportunistic, based on cytology and offered for women aged 25-64 years, with low coverage (30%) and 70% of cancer diagnoses done in advanced stages, without impact on mortality. The current study reports 5-year first-round results of a population-based DNA-HPV testing screening program in a Brazilian city, which intended to be a model for transition to a more efficient program. Program flowchart is simple and current, indicating repetition of a negative test after five years. The first-round (October 2017-September 2022) screened 20,551 women by DNA-HPV testing with 58.7% coverage and 99.4% compliance with the program's targeted age range. Coverage increases to 77.8% when excluding the 'pandemic period'. The DNA-HPV testing was 87.2% negative with 6.2% colposcopy referrals and 84.8% colposcopies performed. A total of 258 high-grade precursor lesions and 29 cervical cancers (mean age = 41.4 years, 83% Stage I) were detected. As a reference, 41,387 cytology tests from the previous program (2012-2016) detected 36 cervical cancers (mean age = 52.0 years, p = 0.0005), with 67% in advanced stages (p < 0.0001). Organizing cervical cancer screening using DNA-HPV testing demonstrated good coverage, high age and colposcopy compliance, and detection of more precancerous lesions and cervical cancers 10 years in advance.

Understanding the association between menstrual health and hygiene attitudes and personal agency among very young adolescents in Sao Paulo, Brazil: A cross-sectional study.

BACKGROUND: Although menstruation is a monthly biological phenomenon, it is shrouded in stigma and shame which directly impacts health, education, gender equality, decent work, and economic growth. However, there is scarce evidence on how personal agency, an individual's ability to access resources, may act as a protective factor to adequate menstrual health and hygiene practices. Therefore, we assess the association between attitudes toward menstruation and personal agency among very young adolescent girls. METHODS: We use cross-sectional data from the Global Early Adolescent Study in São Paulo, Brazil, among 10- to 14-year-old girls who have experienced menarche (n = 325) and completed a home-based self-administered questionnaire in 2021. "Attitudes toward menstruation" was created based on five indicators on a Likert scale, with a higher score indicating more positive attitudes. The main covariate was personal agency, comprised of three scales and modeled as three continuous variables: voice, decision-making power, and freedom of movement. Data were analyzed using multivariable linear regression. RESULTS: Attitudes toward menstruation mean score was 12.5 (range 5-19). Older adolescents (12-14 years-old) had higher mean scores (more positive) than younger adolescents (10-11 years-old) on attitudes toward menstruation, whereas no other sociodemographic or menstrual health indicator (knowledge or access to products) were associated with attitudes toward menstruation. In the multiple regression model, older age and higher freedom of movement remained positively associated with attitudes toward menstruation (ßadjust = 0.5; 95%CI 0.1 to 0.8). CONCLUSION: Positive attitudes toward menstruation are associated with higher freedom of movement among very young Brazilian adolescent girls. The promotion of personal agency should be recognized as key strategies to accelerate young girls' positive approaches to their own menstruation and, consequently, well-being.

Menstrual Health and Hygiene Attitudes are associated with Personal AgencyOur results show that positive attitudes toward menstruation among very young adolescent girls are associated with personal agency, measured through freedom of movement. This information can inform strategies to accelerate young girls' positive approaches to their own menstruation and, consequently, well-being.

Herpesviruses and human papillomaviruses in saliva and biopsies of patients with orofacial tumors.

OBJECTIVES: To determine the prevalence and association of HPV and Herpesviruses in saliva and tissue samples of patients with orofacial tumors. METHODS: Biopsies of tumors were done, and saliva samples were collected from patients with orofacial tumors for the determination of viruses using nested multiplex PCR. Independent variables were sex, age, comorbidities, tumor stage, and length of stay. Outcome variables were the presence or absence of herpesviruses and HPV. Descriptive summaries and inferential statistics were done. RESULTS: A hundred patients were included in the study. Prevalence of herpesviruses and HPV were 17.6 % and 57.0 % in tumors, and 48.3 % and 60.0 % in the saliva of patients respectively. Herpesviruses detected included EBV (21.3 %), HHV-7 (11.2 %), CMV (6.7 %), HSV-1 (5.1 %), HSV-2 (1.1 %), VZV (1.1 %), and Kaposi sarcoma virus (0.6 %). The most prevalent HPV genotypes were HPV-42 (29 %), HPV-43 (22.7 %), HPV-52 (22.2 %), HPV-39 (18.8 %), and HPV-18 (9.1 %). The odds of EBV being detected in malignant orofacial tumors were 2 times that of benign orofacial tumors. HPV DNA in the saliva of patients with orofacial tumors was 69.7 %, compared to 18.2 % of the control sample (p < 0.001). The median length of stay for all participants was 6.5 days, those associated with viruses stayed longer. CONCLUSION: There was a high prevalence of Herpesviruses and HPV in saliva and tumor samples of patients with orofacial tumors, signalling some potential for more work to be done in this area.
