Abstract
Dengue (DENV), chikungunya (CHIKV), and Zika (ZIKV) virus infections are widespread throughout the Rio de Janeiro state. The co-circulation of these emergent arboviruses constitutes a serious public health problem, resulting in outbreaks that can spatially and temporally overlap. Environmental conditions favor the presence, maintenance, and expansion of Aedes aegypti, the primary vector of these urban arboviruses. This study assessed the detection of clusters of urban arboviruses in the Rio de Janeiro state from 2010 to 2019. Notified cases of dengue, chikungunya, and Zika were grouped by year according to the onset of symptoms and their municipality of residence. The study period recorded the highest number of dengue epidemics in the state along with the simultaneous circulation of chikungunya and Zika viruses. The analyzes showed that the central municipalities of the metropolitan regions were associated with higher risk areas. Central municipalities in metropolitan regions were the first most likely clusters for dengue and Zika, and the second most likely cluster for chikungunya. Furthermore, the northwest and north regions were comprised clusters with the highest relative risk for the three arboviruses, underscoring the impact of these arboviruses in less densely populated regions of Brazil. The identification of high-risk areas over time highlights the need for effective control measures, targeted prevention and control interventions for these urban arboviral diseases.

Abstract
BACKGROUND Artificial insemination is widely employed in poultry, but high degrees of bacterial contamination are often observed in semen because of its passage through the cloaca. Consequently, most semen extenders for birds have antibiotics that could aggravate bacterial resistance. METHODS We evaluated the potential of antimicrobial photodynamic therapy (PDT) as an alternative to the use of antibiotics, and assessed whether changes in concentration and incubation time with methylene blue (MB), radiant exposure, and irradiance of light affect spermatozoa activity and bacteria in chicken semen. RESULTS Incubation with MB (< 25 µM) did not alter sperm motility, regardless of the pre-irradiation time (PIT, 1 or 5 min). Following 1 min of PIT with MB at 10 µM, samples were irradiated for 30, 60, 120, and 180 s at irradiances of 44, 29, and 17 mW/ cm² (660 nm LedBox). MB and light alone did not interfere with the analyzed parameters. However, when both factors were associated, increases in light dose led to greater reductions in sperm parameters, regardless of the irradiance used. Besides, PDT conditions that were less harmful to spermatozoa were not able to significantly reduce bacterial colonies in chicken semen. CONCLUSIONS A failure in MB selectivity could explain unsuccessful bacterial reduction following PDT. Further research involving other photosensitizers or conjugating molecules to MB to target microbial cells is needed for PDT application in poultry breeders.

Abstract
BACKGROUND Yellow fever virus (YFV) is an arbovirus that, despite the existence of a safe and effective vaccine, continues to cause outbreaks of varying dimensions in the Americas and Africa. Between 2017 and 2019, Brazil registered un unprecedented sylvatic YFV outbreak whose severity was the result of its spread into zones of the Atlantic Forest with no signals of viral circulation for nearly 80 years. METHODS To investigate the influence of climatic, environmental, and ecological factors governing the dispersion and force of infection of YFV in a naïve area such as the landscape mosaic of Rio de Janeiro (RJ), we combined the analyses of a large set of data including entomological sampling performed before and during the 2017-2019 outbreak, with the geolocation of human and nonhuman primates (NHP) and mosquito infections. RESULTS A greater abundance of Haemagogus mosquitoes combined with lower richness and diversity of mosquito fauna increased the probability of finding a YFV-infected mosquito. Furthermore, the analysis of functional traits showed that certain functional groups, composed mainly of Aedini mosquitoes which includes Aedes and Haemagogus mosquitoes, are also more representative in areas where infected mosquitoes were found. Human and NHP infections were more common in two types of landscapes: large and continuous forest, capable of harboring many YFV hosts, and patches of small forest fragments, where environmental imbalance can lead to a greater density of the primary vectors and high human exposure. In both, we show that most human infections (~ 62%) occurred within an 11-km radius of the finding of an infected NHP, which is in line with the flight range of the primary vectors. CONCLUSIONS Together, our data suggest that entomological data and landscape composition analyses may help to predict areas permissive to yellow fever outbreaks, allowing protective measures to be taken to avoid human cases.

Abstract
The simultaneous circulation of dengue, Zika, and chikungunya poses major challenges for Brazil. Due to climate changes and other associated factors, more than two billion people in the world may be exposed to these arbovirus infections, according to the World Health Organization. The principal strategy for Aedes aegypti control programs is based on the Infestation Index Rapid Survey for Ae. aegypti (LIRAa), a sample survey in which the Building Infestation Index (BII) is used to prioritize areas for intervention. This study analyzed the performance of LIRAa in terms of its sensitivity for predicting dengue epidemics in municipalities in the state of Rio de Janeiro in epidemic years. Incidence rates per municipality for the years 2011, 2012, 2013, 2015, and 2016, plus the BII in October of the previous years. Scatterplots were created, aimed at an exploratory analysis and graphic visualizations of the relationship between the above-mentioned variables, as well as analyses of the Spearman correlation between the BII and the Breteau Index for each year, aimed at estimating the quality of the LIRAa. Comparative analysis of the values for the BII and the respective incidence rates in the period only indicated significant correlation between these variables in 2011/2012 (rs = 0.479; p < 0.01). There was also a correlation between BII and Breteau Index. It is urgent to rethink the parameters established by the LIRAa methodology and invest in alternative methodologies in entomological and epidemiological surveillance that reliably measure transmission risk in the territory and thus design more effective strategies to control these arbovirus infections.

Abstract
Food safety and quality management play a pivotal role in the dairy industry. Milk is a highly nutritious food that also provides an excellent medium for growth of pathogenic microorganisms. Thus, dairy industry focuses most of their processes and costs on keeping contamination levels as low as possible. Thermal processes for microbial decontamination may be effective; however, they cannot provide excellent organoleptic, nutritional, and decontamination properties simultaneously. In this scenario, microbial inactivation by exposure to blue light is a promising alternative method in the food industry due to its intrinsic antimicrobial properties free of any thermal effect. Therefore, this study aimed to determine the inactivation kinetics induced by blue light (λ = 413 nm) against Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Salmonella Typhimurium, and Mycobacterium fortuitum cells suspended in whole milk or saline solution. We also performed a series of optic spectroscopies to investigate possible degradation of milk components. All species were sensitive to photoinactivation suspended either in saline solution or milk. Inactivation kinetics differs significantly depending on the suspension medium and each species is differently affected. All bacterial species tested presented more than 5 log10 of inactivation within less than 2 h of irradiation (720 J/cm2). Infrared spectroscopy did not reveal any significant alteration in any of the milk constituents (e.g., sugars, proteins, and lipids). Riboflavin (vitamin B2) was the only significantly degraded constituent found. Therefore, we conclude that microbial inactivation performed by blue light presents extraordinary potential for processes in the dairy industry.

Abstract
BACKGROUND In Brazil, the Yellow Fever virus (YFV) is endemic in the Amazon, from where
it eventually expands into epidemic waves. Coastal south-eastern (SE)
Brazil, which has been a YFV-free region for eight decades, has reported a
severe sylvatic outbreak since 2016. The virus spread from the north toward
the south of the Rio de Janeiro (RJ) state, causing 307 human cases with 105
deaths during the 2016-2017 and 2017-2018 transmission seasons. It is
unclear, however, whether the YFV would persist in the coastal Atlantic
Forest of RJ during subsequent transmission seasons. OBJECTIVES To conduct a real-time surveillance and assess the potential persistence of
YFV in the coastal Atlantic Forest of RJ during the 2018-2019 transmission
season. METHODS We combined epizootic surveillance with fast diagnostic and molecular,
phylogenetic, and evolutionary analyses. FINDINGS Using this integrative strategy, we detected the first evidence of YFV
re-emergence in the third transmission season (2018-2019) in a dying howler
monkey from the central region of the RJ state. The YFV detected in 2019 has
the molecular signature associated with the current SE YFV outbreak and
exhibited a close phylogenetic relationship with the YFV lineage that
circulated in the same Atlantic Forest fragment during the past seasons.
This lineage circulated along the coastal side of the Serra do Mar mountain
chain, and its evolution seems to be mainly driven by genetic drift. The
potential bridge vector Aedes albopictus was found probing
on the recently dead howler monkey in the forest edge, very close to urban
areas. MAIN CONCLUSIONS Collectively, our data revealed that YFV transmission persisted at the same
Atlantic Forest area for at least three consecutive transmission seasons
without the need of new introductions. Our real-time surveillance strategy
permitted health authorities to take preventive actions within 48 h after
the detection of the sick non-human primate. The local virus persistence and
the proximity of the epizootic forest to urban areas reinforces the concern
with regards to the risk of re-urbanisation and seasonal re-emergence of
YFV, stressing the need for continuous effective surveillance and high
vaccination coverage in the SE region, particularly in RJ, an important
tourist location.

Abstract
The opossum has been suggested as an animal model for biomedical studies due to its adaptability to captivity and number of births per year. Despite many studies on morphology and experimental neurology using this opossum model, the literature does not offer details of the nerves of the lumbosacral plexus in this species. Ten lumbosacral plexus were dissected to describe the peripheral innervations of the Brazilian Common Opossum (Didelphis aurita) and compare the results with Eutheria clade species. The tensor fasciae latae muscle was absent and there was only one sartorius muscle for each limb. The distribution of the nerves were similar to other mammals, except for the caudal gluteal nerve, sartorius muscle innervations and the position of the pudendal nerve which arose from the major ischiatic foramen together with the ischiatic nerve, the cranial gluteal nerve and the caudal gluteal nerve. No anatomical variation was found. The special position of the pudendal nerve suggested that the Brazilian Common Opossum is a better model than rats or rabbits in surgical procedures with that specific nerve. In addition, the study revealed that the pelvic limb nerves are not an invariable structure of reference for muscle homology and homonym as reported previously. New investigation using other species of opossums are necessary to best comprehend the lumbosacral plexus distribution in the Methatheria clade and to confirm that other opossum species is eligible as a good model for pudendal nerve studies.

Since no general analytical time-dependent solutions are found for such a nonlinear Kramers equation, an ansatz is considered and the corresponding asymptotic behavior is studied and compared with those known for the standard linear Kramers equation. The H-theorem is analyzed for this equation and its connection with Tsallis entropy is investigated. An application is discussed, namely the motion of Hydra cells in two-dimensional cellular aggregates, for which previous measurements have verified q-Gaussian distributions for velocity components and superdiffusion. The present analysis is in quantitative agreement with these experimental results.

Abstract
Antimicrobial photodynamic therapy (APDT) combined with endodontic treatment has been recognized as an alternative approach to complement conventional root canal disinfection methods on bacterial biofilms. We developed an in vitro model of bioluminescent Candida albicans biofilm inside curved dental root canals and investigated the microbial reduction produced when different light delivery methods are employed. Each light delivery method was evaluated in respect to the light distribution provided inside curved root canals. After conventional endodontic preparation, teeth were sterilized before canals were contaminated by a bioluminescent strain of C. albicans (CEC789). Methylene blue (90 μM) was introduced into the canals and then irradiated (λ = 660 nm, P = 100 mW, beam diameter = 2 mm) with laser tip either in contact with pulp chamber or within the canal using an optical diffuser fiber. Light distribution was evaluated by CCD camera, and microbial reduction was monitored through bioluminescence imaging. Our findings demonstrated that the bioluminescent C. albicans biofilm model had good reproducibility and uniformity. Light distribution in dental tissue was markedly dependent on the light delivery system, and this strategy was directly related to microbial destruction. Both light delivery systems performed significant fungal inactivation. However, when irradiation was performed with optical diffuser fiber, microbial burden reduction was nearly 100 times more effective. Bioluminescence is an interesting real-time analysis to endodontic C. albicans biofilm inactivation. APDT showed to be an effective way to inactivate C. albicans biofilms. Diffuser fibers provided optimized light distribution inside curved root canals and significantly increased APDT efficiency.

Abstract
BACKGROUND Vaginal candidiasis (VC) is a disease that affects thousands of women of childbearing age, mainly caused by Candida albicans fungus. Photodynamic therapy (PDT) uses photosensitizing substances that are nontoxic in the dark, but able to produce reactive oxygen species when they are subjected to a light source. In this work our purpose was to investigate PDT effects on fungal burden and inflammatory cells in a murine model of C. albicans-induced vaginal candidiasis. METHODS Female BALB/c mice 6-10 weeks were estrogenized and maintained in this state during all experiment. After 72h, mices were inoculated intravaginally (IV) with 20μL of 2×10(5)C. albicans cells suspension. Mice were separated into 5 groups after five days: H (healthy), PBS (control), laser, MB (methylene blue) and PDT. PDT and MB groups received IV 20μL solution with 1mM of MB, others received PBS. PDT and laser groups were irradiated with a red laser (100mW, 660nm) in one (36J, 6min) or two sessions (18J, 3min). After the end of treatment, mice were submitted to microbiological and histomorphometric analysis with ImageJ software. Data were plotted by mean values and standard deviations of CFU/mL and percentage of inflammatory cells area. ANOVA and Bonferroni post-test were used and data were considered significant when p<0.05. RESULTS PDT significantly reduced C. albicans after the two tested protocols, however, percentage area of inflammatory cells was significantly reduced just with two sessions of PDT. CONCLUSIONS PDT with MB and red laser is a promising therapy for VC. It is able to reduce fungal infection in biofilm and inflammatory signals associated with VC in a murine model of vaginitis.

Abstract
Estudo transversal realizado com o objetivo de avaliar uso do Coping Religioso-Espiritual (CRE) e verificar suas possíveis modulações com o padrão de consumo de alcoólicos em pacientes atendidos em ambulatório de hepatologia entre abril e dezembro de 2009, utilizando o CAGE, o AUDIT e a escala CRE. Foram encontradas associações entre coping religioso-espiritual negativo (CREN) e consumo de alcoólicos na vida no último ano e com a combinação resultante. Sujeitos identificados como CAGE negativos com uso de baixo risco no último ano tiveram frequência acima da esperada na categoria abaixo da mediana. Os identificados como CAGE positivo com uso de médio risco foram relativamente mais frequentes na categoria acima da mediana (p=0,017). Resultados reforçam a relevância do CREN na avaliação de eventos relacionados com a saúde.

Abstract
OBJECTIVE To investigate mental health dropout rates in secondary care and to identify possible associations between this variable and social, demographic, psychopathologic, and health care process-related variables. METHOD This prospective, observational study included 994 patients referred to a secondary service by four primary care units and evaluated by a specialist mental health team between 2004 and 2008. The dependent variable was treatment dropout. Bivariate analyses investigated possible associations between treatment dropout and 57 independent variables. RESULTS The overall dropout rate from specialist mental health treatment was relatively low (mean = 25.6%). Only four independent variables were associated with dropout: one socioeconomic, two psychopathological, and one health care process variable. All associations were marginally significant (p < 0.1). CONCLUSION Our findings suggest that family members, patients, and health care professionals are well engaged in this mental health care system based on a model of primary care. The use of this mental health model of care should be extended to other regions of our country.

Abstract
OBJECTIVE Assess the odds of having an initial claim for statutory sickness benefit awarded (ascribed to mental disorder as the main registered diagnosis), in relation to institutional, clinical, sociodemographic and welfare factors in Juiz de Fora-MG, Brazil. METHOD Two models of logistic regression, taking into account the categories of the medical examiners, were built with the aim of characterizing the relative weight of several variables affecting the medical conclusion. RESULTS The factors more strongly related to an award of benefit were claimants assessed by a physician without a specialization in psychiatry; with a diagnosis of psychosis; up to 29 years of age; with other non-psychiatric (musculoskeletal and cardiovascular) co-morbidities; registered with the national insurance system as employed; and male. DISCUSSION In both models, examiners with a specialization in psychiatry were associated with a lower likelihood of award of benefit. This suggests that examinations undertaken by doctors having a specialty related to the diagnosis supporting the sickness benefit claim are stricter than those undertaken by non-specialists. CONCLUSION The results suggest that benefit award odds were associated with the specialty of the examiner, medical diagnosis, age, gender and claimant category.

Abstract
UNLABELLED This article is a preliminary study on possible influences of legal regulation changes (Copes and PP) on the result of initial expertise examination in Juiz de Fora (State of Minas Gerais, Brazil), following a request for social benefits due to a mental disorder. METHOD retrospective analysis of data drawn from an official data bank (Dataprev) related to examinations concluded between July/2004 and December/2006. Four periods were considered: (1º) July/2004 to July/ 2005 before the legal regulation Copes took effect; (2º) August/2005 to November/2005, with Copes in effect and examinations by third part experts; (3º) December/2005 to April/2006, without third part experts; (4º) May/2006 to December/2006, with PP in effect. RESULTS reduction on the frequency of benefit granting from 81.9% to 49.5% from 1º to 4º period. Increase of favorable conclusions on requests for re-evaluations (from 52.0% in 1º period to 75.3% after Copes) and reduction in 4º period (36.5%). Reduction on average number of benefit renewal (from 3.5 to 1.7, respectively in 1º and 4º periods). The mean period of work dismissal was longer in 1º period and shorter in 4º period (respectively 397.4 and 247.6 days). The results highlighted changes on the profile of benefits granted during the period of time in which the new regulations came into force.

Abstract
INTRODUCTION Low adherence rates are frequently found in alcoholics' treatment programs. Many characteristics of alcoholics have already been associated to longer adherence or to higher drop-out rates. Adherence is an outcome already pointed as a simple and practical measure to evaluate treatment results. This study aimed to identify characteristics of alcoholics of a public outpatient treatment program associated to superior adherence, i.e., to longer permanence periods in treatment. METHOD This study included 634 alcoholics; from these, 329 concluded the program's assessment stage and 305 did not conclude or fulfill the program's exclusion criteria. Initially, we analyzed socio-demographic differences between patients who completed or did not complete assessment. Crosstabs were performed to verify the association of all other 814 variables in the data bank to adherence to treatment. Logistic regression of variables found at least marginally significant was the performed: first within each dimension involved, contributing to the selection of variables for the multidimensional model. Pearson's Qui-square test was used to verify possible associations. RESULTS Only two variables significantly differed patients who completed and did not complete assessment: place of birth and mean age. In bivariate analysis, 65 variables were associated to adherence; however, only five remained significant (p < 0.05) after logistic regression. In the final model, variables significantly associated to adherence were: did not eat while drinking; evaluated as having high insight level; (presented DSM-IV criterion 6 for Dependence (important social, occupational, or recreational activities are given up or reduced because of substance use); when increased consumption, drank to relieve chronic malaise; abdominal pain in the last 30 days before evaluation. CONCLUSION The results of this study indicate that, differently from preliminary conclusions, the therapeutic standard used in the program evaluated--namely its focus on the approach of psychiatric comorbidity--did not remain as one of the most relevant factors associated to longer adherence to treatment. Therefore, the results support the need of new studies directed to the assessment of these subgroups that more quickly dropped-out of the treatment routinely offered, in order that diagnose and treatment approaches may be altered in order to become more efficient and effective to its clients.

OBJETIVOS: Analisar comparativamente os registros médico-periciais dos diagnósticos de segurados do INSS requerentes de auxílio-doença apresentando transtorno mental. MÉTODO: Estudo retrospectivo de registros de perícias iniciais realizadas em agências da Previdência Social de Juiz de Fora, MG, entre julho/2004 e dezembro/2006. Foram realizadas análises bivariadas de acordo com o local de realização da perícia, categoria de perito médico examinador e período da avaliação RESULTADOS: Transtornos depressivos leves ou moderados e transtornos persistentes do humor (39,6%) e os transtornos de ansiedade (34,5%) - quadros mais leves que não comprometeriam tanto a capacidade laborativa - foram os diagnósticos mais frequentemente registrados. Dentre as comorbidades, transtornos mentais foram mais frequentes (33,6%) que quadros clínicos, especialmente na agência Riachuelo, entre peritos concursados após 2005 e no quarto período estudado. A concordância entre o diagnóstico do benefício atual e o do benefício anterior foi baixa, inferior a 50% na maioria dos casos, mesmo para transtornos mentais graves e com características clínicas mais bem definidas, como as psicoses. A maior taxa de concordância ocorreu com os transtornos por uso de substâncias psicoativas entre peritos credenciados (66,7%). CONCLUSÃO: Este estudo evidencia possíveis falhas no treinamento dos peritos médicos de Juiz de Fora no que se refere ao registro do diagnóstico dos transtornos mentais dos segurados avaliados.

Abstract
OBJECTIVE The aims of the present study were to investigate the effect of low-intensity laser irradiation on the total number of mast cells as well as the percentage of degranulation in human gingiva. Blood vessel dilation was also evaluated. BACKGROUND DATA It has been proposed that low-intensity laser irradiation can ameliorate pain, swelling, and inflammation. In periodontal tissue, mast cells may influence either the destructive events or the defense mechanism against periodontal disease via secretion of cytokines and through cellular migration to improve the healing process. Mast cells play an important role in the inflammatory process. METHODS Twenty patients with gingival enlargement indicated for gingivectomy were selected. Gingival fragments were obtained from each patient and divided into three different groups before surgery. One fragment was removed without any irradiation. The two others were submitted to punctual irradiation with an energy density of 8 J/cm(2) at an output power of 50 mW at 36 Hz for 36 sec before gingivectomy. Nondegranulated and degranulated mast cells were counted in five areas of the gingival fragment connective tissue. Major and minor diameters of the blood vessels were also measured. RESULTS Both red and infrared radiation promoted a significant increase in mast cell degranulation compared to controls; however, no statistically significant differences (p > 0.05) were observed between the irradiated groups. No significant differences among the groups were observed regarding blood vessel size. CONCLUSION The results suggests that red and infrared wavelengths promote mast cell degranulation in human gingival tissue, although no dilation of blood vessels was observed. The effects of premature degranulation of mast cells in human tissue and the laser radiation protocol applied in this study encourage further investigations to extend these results into clinical practice.

Abstract
A ocorrência de abandono de tratamento psiquiátrico de nível secundário é uma relevante questão clínica e econômica. Taxas de abandono em psiquiatria são mais altas que em outras especialidades médicas. Estudos publicados nos últimos 15 anos têm identificado diversos fatores estatisticamente associados ao não-comparecimento às consultas e/ou ao abandono de tratamento em saúde mental. OBJETIVO: Avaliar variáveis demográficas, psicopatológicas, de diagnóstico e tratamento enquanto possíveis preditores de abandono de tratamento em serviço especializado de saúde mental. MÉTODO: Estudo observacional, avaliando 896 pacientes encaminhados, no período de abril de 2004 a março de 2006, por Unidades Básicas de Saúde da área de abrangência do serviço especializado. RESULTADOS: Pacientes solteiros, com idade abaixo da média do grupo (39,2 anos) e desempregados abandonaram significantemente mais o tratamento. Duas variáveis relativas ao exame psicopatológico se associaram significantemente com abandono de tratamento (memória quanto ao passado recente e relação do humor com fatos reais, atuais). Pacientes adultos que receberam diagnóstico psiquiátrico de oligofrenia abandonaram significantemente menos e pacientes com diagnóstico relativo aos transtornos da infância e adolescência (F80-F98 da CID-10) também abandonaram significantemente mais o tratamento. O registro de comorbidade psiquiátrica e tratamento exclusivamente farmacológico se associaram a não abandono do tratamento. CONCLUSÃO: Os resultados confirmam achados de diferentes autores da evidência de características associadas a abandono ao tratamento. Tais achados sugerem que determinados subgrupos de pacientes necessitem de abordagens customizadas, a fim de influenciar positivamente sua adesão final ao tratamento indicado.

Abstract
Tendo em vista os diversos problemas associados ao assim chamado uso de risco de álcool, ele é considerado uma relevante questão de saúde pública. Uma das estratégias de prevenção secundária recomendadas é a utilização de instrumentos de rastreamento associados a intervenções breves em serviços de atenção primária à saúde. O objetivo deste estudo foi avaliar o processo de implantação desta estratégia na rotina de atenção primária à saúde da cidade de Juiz de Fora, Minas Gerais, Brasil. Foi utilizada uma abordagem qualitativa, incluindo a aplicação de entrevistas semi-estruturadas a gestores e/ou profissionais da assistência do Sistema Municipal de Saúde, associadas à análise de conteúdo e observação participante. Os resultados indicam que há dificuldades para a implantação efetiva destas rotinas, tanto em relação aos gestores quanto aos profissionais envolvidos diretamente na sua execução. Quanto aos profissionais destacam-se a restrição da abordagem a dependentes de álcool e a falta de motivação dos profissionais para trabalhos preventivos. Quanto aos gestores, foram detectadas dificuldades práticas no processo de organização e gerenciamento, a despeito de um afirmado interesse no projeto.

Abstract
BACKGROUND The levels of interleukin-1beta (IL-1beta) have been reported to be higher in sites with periodontitis than in healthy controls. This may be the result of a more severe inflammation and/or constitutional differences in IL-1beta production. Our aim was to test the hypothesis that the level of IL-1beta in gingival crevicular fluid (GCF) is a characteristic trait of periodontitis, regardless of the degree of tissue destruction. As a secondary aim, we investigated the correlation between IL-1beta and neutrophil elastase. An untreated population was used. METHODS GCF samples from inflamed sites in 13 patients with gingivitis (GG), and from inflamed sites with shallow (GP) and deep (PP) pockets in 18 patients with periodontitis were collected. Interleukin-1beta, elastase-alpha-1-antitrypsin complex (E-A1AT), alpha-1-antitrypsin (A1AT), and alpha-2-macroglobulin (A2MG) were measured with ELISA. Elastase activity was measured with a specific substrate. RESULTS The concentration of IL-1beta was significantly higher in PP than in GG, but no significant differences were detected between PP and GP. A weak positive correlation between the elastase activity and IL-1beta was also observed. The elastase activity had a tendency to be higher in PP, although no significant difference was found among the 3 groups. The concentrations of E-A1AT, A1AT, and A2MG were similar in the 3 types of sites. CONCLUSIONS The levels of IL-1beta in GCF were increased in samples from periodontitis patients, regardless of the severity of disease at the sampled site, suggesting that the levels of IL-1beta are typical of a given patient.
