Cerebral Venous Thrombosis in Pediatric Age: Risk Factors and Prognosis.

INTRODUCTION: Cerebral venous thrombosis (CVT) is a rare but potentially fatal disease in pediatric age with an important morbimortality. In adults several factors have been associated with worse outcomes, however there are still few studies in children. This study aims to identify risk factors associated with clinical manifestations and long-term sequelae in pediatric CVT. METHODS: Retrospective analysis of pediatric inpatients admitted to a tertiary-care hospital due to CVT between 2008 and 2020. RESULTS: Fifty-four children were included, 56% male, median age of 6.5 years (9 months-17.3 years). Permanent risk factors were identified in 13 patients (malignancy, 8; hematologic condition, 5) and transient risk factors in 47, including head and neck infections (57%) and head trauma (15%). Multiple venous sinuses involvement was present in 65% and the deep venous system was affected in four patients. Seventeen percent had intracranial hemorrhage and 9% cerebral infarction. Sixty-four percent of patients with multiple venous sinuses involvement presented with severe clinical manifestations: impaired consciousness, intracranial hypertension, acute symptomatic seizures or focal deficits. Regarding long-term prognosis, six patients had major sequelae: epilepsy (n = 3), sensory motor deficits (n = 2), and cognitive impairment (n = 3). Permanent risk factors were associated with severe clinical manifestations (p = 0.043). Cerebral infarction and intracranial hemorrhage were associated with major sequelae (p = 0.006 and p = 0.03, respectively, adjusted for age and sex). CONCLUSION: Permanent risk factors, involvement of multiple venous sinuses, intracranial hemorrhage, and cerebral infarction, were related to worse prognosis. Detection and early management of risk factors may limit CVT extension and reduce its morbimortality.

TeleCleft: Development and Evaluation of a Mobile Application for Monitoring Cleft Patients.

OBJECTIVE: Development and evaluation of a mobile application for remote monitoring and guidance of pediatric patients diagnosed with cleft lip and/or palate (CL ± P) and their caregivers. DESIGN: This is a pilot cross-sectional, applied, and quantitative study. SETTING: The study was conducted in two tertiary care treatment centers in Brazil. PARTICIPANTS: The participants included 20 caregivers and infants undergoing treatment with nasoalveolar molding (NAM) for CL ± P. INTERVENTIONS: The intervention involved using the TeleCleft mobile application for remote monitoring and guidance of caregivers and infants during NAM treatment. MAIN OUTCOME MEASURE(S): The main outcome measures included usability and satisfaction of users with the TeleCleft application. RESULTS: The results showed high usability and satisfaction ratings among users of the TeleCleft application. Most participants found remote monitoring to be effective and expressed positive opinions about its convenience and usefulness. CONCLUSION: TeleCleft could be a viable tool for remote monitoring and guidance, reducing the need for patients and caregivers to travel to treatment centers, which could potentially alleviate the burden of care faced by families during the journey of CL ± P treatment.

Response to 1064 nm Nd:YAG LASER in treatment of vulvar Fordyce's Angiokeratoma: case report.

Fordyce's Angiokeratoma (AKF) is a benign type of vascular lesion that affects the male and female external genitalia. Prevalence is unknown and there is no apparent hereditary component. Diagnosis can be suggested by ectoscopy, by the presence of purple, bluish, black or red papules on the vulva, clitoris, scrotum, or penis body or glans. Most patients are asymptomatic. Various methods have been used for treatment, including surgery, electrocoagulation, chemical cauterization, sclerotherapy, and LASER. The effectiveness and complications of these therapies are varied. The purpose of this article is to report the case of a 56-year-old woman with abundant and painful vulvar lesions treated with a 1064 nm Nd:YAG LASER. The 1064 nm Nd:YAG LASER proved to be a viable therapeutic option, with satisfactory results and a low rate of complications.

The Associations Between Physician-Patient Communication and Adjustment Outcomes of Patients and Physicians: A Systematic Review and Meta-Analysis of Correlations.

Physician-Patient communication (PPC) has been linked to patient adjustment outcomes. However, conflicting results have been reported and previous systematic reviews showed some methodological weaknesses. It has also been suggested that PPC is related to physicians' own adjustment outcomes. This systematic review aims to explore and synthesize the associations between PPC and both patient and physician adjustment outcomes. A systematic search was conducted primarily in five databases and 11.488 non-duplicated articles were identified. Forty-five studies met the eligibility criteria and data extraction was performed for sample characteristics, PPC measurement, adjustment outcomes under examination and main outcomes. The observed results showed that the majority of the included studies were cross-sectional, assessed PPC by proxy-report and reported an overall positive association with patients' adjustment outcomes. None of the studies examined the association between PPC and physicians' adjustment outcomes. Thirty-three studies were meta-analyzed and showed a positive and significant association between PPC and patients' adjustment outcomes (r = .16). Due to the small number of studies included in the meta-analysis, the heterogeneity was high. Subgroup analysis could not identify sources for heterogeneity. Research on the associations between PPC and physicians' own adjustment outcomes is warranted. Future studies should be rigorous in defining clear PPC definitions, directionality of communication processes, and study design.

Microcotylidae (Monogena) parasites of snappers (Perciformes: Lutjanidae) collected from the northeast coast of Brazil.

Monogeneans are a diverse group of flatworms, being ectoparasites of marine and freshwater fish, with great morphological and ecological variety. Analyzes of monogenetics in fish with great habitat diversity such as snappers are scarce in the literature, which already emphasizes the need for an update in this regard. The presente study found, morphologically characterized and mapped the geographic distribution and in known hosts the species Microcotyloides incisa and Microcotyloides impudicus, describing the first occurrence of these monogeneans for South America and in new hosts. The survey of hosts in the literature shows that M. incisa seems to have a greater Affinity with congener species of Lutjanidae and fish from other families, which may indicate a preference or specificity for fish of this family because they are congeners of their host type. The introduction of these parasites into South American waters may have occurred due to the migratory behavior of snappers, which are well distributed along the Mexican coast, where the parasites are usually reported. Here, we also bring the first occurrence of M. incisa for Lutjanus analis and Lutjanus jocu and M. impudicus for Ocyurus chrysurus and Lutjanus synagris, helping in the mapping and distribution of these monogenetic species in the Americas.

Antiviral activity of aframomum melegueta against severe acute respiratory syndrome coronaviruses type 1 and 2.

Plant-based compounds with antiviral properties against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) have been identified in Aframomum melegueta through computational models. The seed extract have been traditionally used to treat different illnesses. In this study, ethanolic extracts were prepared for six commercial samples of A. melegueta seeds. Antiviral activity was tested using the XTT cytotoxicity assay and cell-based SARS-CoV-1 and 2 pseudoviral models. The presence of gingerols and other non-volatile components in the seed extracts was determined using an Agilent 1290 UPLC/DAD in tandem with an Agilent 6546 QTOF-MS. Our results showed selective antiviral activity with TI values as high as 13.1. Fifteen gingerols were identified by chromatographic analysis, with 6-gingerol being the dominant component in each seed extract. A combination of 6-gingerol with techtochrysin, previously identified in computational models as a potential active ingredient against SARS-CoV-2, demonstrated additive antiviral activity with CI values between 0.8715 and 0.9426. We confirmed the antiviral activity of A. melegueta predicted through computational models and identified a different compound, 6-gingerol, as a potential active ingredient.

Griffithsin and Carrageenan Combination Results in Antiviral Synergy against SARS-CoV-1 and 2 in a Pseudoviral Model.

Over 182 million confirmed cases of COVID-19 and more than 4 million deaths have been reported to date around the world. It is essential to identify broad-spectrum antiviral agents that may prevent or treat infections by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) but also by other coronaviruses that may jump the species barrier in the future. We evaluated the antiviral selectivity of griffithsin and sulfated and non-sulfated polysaccharides against SARS-CoV-1 and SARS-CoV-2 using a cytotoxicity assay and a cell-based pseudoviral model. The half-maximal cytotoxic concentration (CC50) and half-maximal effective concentration (EC50) were determined for each compound, using a dose-response-inhibition analysis on GraphPad Prism v9.0.2 software (San Diego, CA, USA). The therapeutic index (TI = CC50/EC50) was calculated for each compound. The potential synergistic, additive, or antagonistic effect of different compound combinations was determined by CalcuSyn v1 software (Biosoft, Cambridge, UK), which estimated the combination index (CI) values. Iota and lambda carrageenan showed the most potent antiviral activity (EC50 between 3.2 and 7.5 µg/mL). Carrageenan and griffithsin combinations exhibited synergistic activity (EC50 between 0.2 and 3.8 µg/mL; combination index <1), including against recent SARS-CoV-2 mutations. The griffithsin and carrageenan combination is a promising candidate to prevent or treat infections by SARS-CoV-1 and SARS-CoV-2.

Elimination of saphenous reflux after tributary sclerotherapy: report of two cases.

Most patients with chronic venous disease (CVD) and reflux in the saphenous vein are treated with saphenous stripping or ablation. The venous hemodynamics approach offers the possibility of treating saphenous reflux without eliminating the saphenous vein. We present 2 cases in which venous reflux was eliminated while preserving the great saphenous vein, after treatment with hemodynamic sclerotherapy using a protocol of synergic use of Dextrose and long pulse Nd YAG 1064 laser. These cases show that treating the tributaries responsible for saphenous reflux can correct hemodynamic imbalances and restore normal flow in the great saphenous vein with improvements in symptoms and esthetics. Long-term results are still uncertain.

A maioria dos pacientes com insuficiência venosa crônica e refluxo na veia safena é tratada com retirada ou ablação da safena. A hemodinâmica venosa traz a possibilidade de tratar esses pacientes sem eliminar a veia safena. Nós apresentamos dois casos de refluxo parcial de veia safena magna resolvidos com escleroterapia hemodinâmica. Usamos um protocolo de uso sinergístico de glicose 75% e Nd-YAG laser 1064. Os casos nos mostram que o tratamento das tributárias pode corrigir o refluxo da veia safena e obter melhora clínica e cosmética. Os resultados de longo prazo ainda são incertos.

Bilateral foam polidocanol sclerotherapy of great saphenous veins and their tributaries in synchronous procedure.

BACKGROUND: Chronic venous insufficiency is a highly prevalent disease. Advanced cases have high morbidity. OBJECTIVES: To evaluate the risks and benefits of foam sclerotherapy in patients who underwent bilateral treatment of the great saphenous veins in a single procedure, in selected cases of advanced venous insufficiency. METHODS: We retrospectively reviewed 55 patients (110 limbs) with bilateral incompetence of the great saphenous veins who had undergone foam sclerotherapy treatment bilaterally, using a maximum dose of 20 ml of foam per patient and inelastic compression. RESULTS: In 81 (73.6%) of the 110 saphenous veins analyzed, occlusion was obtained in the first session. After a second session this figure rose to 106 (96.3%) and all 110 (100%) veins were occluded after three sessions. Bilateral occlusion of the great saphenous veins was achieved in 27 patients (50%) in one session, in 34 (62%) patients in two sessions, and in 55 (100%) patients in three sessions. At 42 days after sclerotherapy, there was complete ulcer healing in seven (63%) of the 11 patients with ulcers and partial healing in 3 (27%) of these patients. One patient (1.8%) had self-limited lipothymia and visual scotomas, 3 patients (5.45%) had skin spots, and 19 patients (34.5%) developed retained intravascular coagulum. CONCLUSIONS: Bilateral foam sclerotherapy in a synchronous procedure is an option to be considered for treatment of varicose veins of the lower limbs.

Preservation of Forensic Evidence by Nurses in a Prehospital Emergency Care Service in Brazil.

Violence is a growing public health problem worldwide. Nurses increasingly must perform forensic procedures with the responsibility to collect, document, preserve, and store evidence that may be used in the investigation of a violent crime. However, few nurses receive education in forensic evidence collection as part of their training. This study aimed to evaluate the relationship between nurses' knowledge and performance of forensic evidence procedures. This is a descriptive survey study of nurses working in a prehospital emergency care service in Aracaju, Brazil. A 32-question survey related to forensic evidence knowledge and procedures was completed by 128 nurses. Descriptive statistics and Kendall's Tau-b were used to describe the sample and evaluate correlations. Results revealed an overall linear relationship between knowledge and performance of forensic evidence procedures (r = .69). The strongest correlation was between knowledge and documentation (r = .71). Weaker correlations were demonstrated between knowledge and evidence collection (r = .47), evidence preservation (r = .47), and overall evidence procedure execution (r = .53). Forensic nursing knowledge is related to forensic evidence procedure performance. Although the study showed that nurses agreed forensic evidence procedures are important for criminal investigations, most reported they were unprepared to carry out these procedures. The need for additional training and adherence to established institutional protocols are identified as contributing factors.

The Development of an International Oncofertility Competency Framework: A Model to Increase Oncofertility Implementation.

BACKGROUND: Despite international evidence about fertility preservation (FP), several barriers still prevent the implementation of equitable FP practice. Currently, oncofertility competencies do not exist. The aim of this study was to develop an oncofertility competency framework that defines the key components of oncofertility care, develops a model for prioritizing service development, and defines the roles that health care professionals (HCPs) play. MATERIALS AND METHOD: A quantitative modified Delphi methodology was used to conduct two rounds of an electronic survey, querying and synthesizing opinions about statements regarding oncofertility care with HCPs and patient and family advocacy groups (PFAs) from 16 countries (12 high and 4 middle income). Statements included the roles of HCPs and priorities for service development care across ten domains (communication, oncofertility decision aids, age-appropriate care, referral pathways, documentation, oncofertility training, reproductive survivorship care and fertility-related psychosocial support, supportive care, and ethical frameworks) that represent 33 different elements of care. RESULTS: The first questionnaire was completed by 457 participants (332 HCPs and 125 PFAs). One hundred and thirty-eight participants completed the second questionnaire (122 HCPs and 16 PFAs). Consensus was agreed on 108 oncofertility competencies and the roles HCPs should play in oncofertility care. A three-tier service development model is proposed, with gradual implementation of different components of care. A total of 92.8% of the 108 agreed competencies also had agreement between high and middle income participants. CONCLUSION: FP guidelines establish best practice but do not consider the skills and requirements to implement these guidelines. The competency framework gives HCPs and services a structure for the training of HCPs and implementation of care, as well as defining a model for prioritizing oncofertility service development. IMPLICATIONS FOR PRACTICE: Despite international evidence about fertility preservation (FP), several barriers still prevent the implementation of equitable FP practice. The competency framework gives 108 competencies that will allow health care professionals (HCPs) and services a structure for the development of oncofertility care, as well as define the role HCPs play to provide care and support. The framework also proposes a three-tier oncofertility service development model which prioritizes the development of components of oncofertility care into essential, enhanced, and expert services, giving clear recommendations for service development. The competency framework will enhance the implementation of FP guidelines, improving the equitable access to medical and psychological oncofertility care.

The time is now: An exploratory study regarding the predictors of female cancer patients' decision to undergo fertility preservation.

INTRODUCTION: This cross-sectional exploratory study aimed to examine the female cancer patients' personal and health care-related variables mostly associated with their decision whether to preserve or not their fertility, in order to know more about the influence of attitudinal and health care-related variables on this decision where fertility preservation (FP) is fully covered by the National Health System. METHODS: Childbearing attitudes, health care-related information, FP motivations and childbearing motivations were assessed, in a clinical setting, to female cancer patients in childbearing age, who were undergoing the FP decision-making process. RESULTS: This study included 89 participants (82% response rate). Those who decided to undergo FP attributed more value to the reasons for FP and less value to the reasons against FP than those who decided not to undergo FP. Not having children, strongly valuing pregnancy after cancer and attributing low value to the implications of the postponement of cancer treatments were significant and independently associated with deciding to preserve fertility. CONCLUSION: The decision to pursue FP is mainly influenced by three factors: the absence of children, attributing high value to trying to ensure future pregnancy and attributing low value to the possible postponement of cancer therapy in order to have time to preserve fertility.

First record of Dichelyne (Dichelyne) bonacii (Nematoda, Cucullanidae) parasitizing the intestine of two species of lutjanid fish (Perciformes, Lutjanidae) on the northeast Brazilian coast.

Lutjanids are marine fish and commonly inhabit coral reefs, which have migratory habits and feed in a general way, due to these characteristics, are susceptible to infections by parasites, such as cuculanid nematodes. This work aimed to report for the first time, the occurrence of Dichelyne (Dichelyne) bonacii in Brazil, in two new hosts, Lutjanus analis and Rhomboplites aurorubens, acquired from local artisanal fishermen at the Aracaju city public fishing terminal (10 ° 54'17 "S37 ° 2'56" W), northeast coast of Brazil. Adult nematodes were collected from the intestinal tract of the hosts, clarified in Aman's Lactophenol and were briefly described here. Three adult males and five gravid females were found, indicating that the two species of fish acted as definitive hosts. Currently, this species of parasite has been reported only from fish collected in the coast of Mexico, which makes this work the first record of this parasite in Brazilian coastal waters. The results show that probably the range of hosts and the distribution of D. (Dichelyne) bonacii is not as restricted as data pointed in the literature, being a little wider, extending also to waters that bathe the Brazilian coast.

Portuguese oncologists' practices regarding female fertility preservation: Which barriers most relate to these practices?

This study aims to investigate the current practice patterns of Portuguese oncologists with different clinical specialties regarding female fertility preservation (FP) and to determine the relative endorsement of different barriers to these practices. A total of 111 doctors with different clinical specialties assisting female cancer patients of childbearing age at Portuguese clinical institutions completed a self-report questionnaire to assess their current practice patterns regarding female FP and their perceptions of the barriers to these practices. Although the majority of the oncologists reported discussing the reproductive future with their patients, 2.8% and 7.2% of these clinicians reported never informing about the risk of infertility and about FP, respectively, and 75.8% of the participants have referred fewer than ten patients to a reproductive medicine doctor. Time with patients was the strongest endorsed barrier to these practices. A stronger endorsement of the barriers "oncologists' communication skills" and "patient-related factors" was related to a lower frequency of informing about both the risk of cancer-related infertility and about FP. It is important to overcome the intrinsic barriers that emerged as being the most relevant to oncologists' FP practices and that can be modified, namely the lack of communication skills and the oncologists' perceptions of their patients' characteristics.

Female cancer patients' perceptions of the fertility preservation decision-making process: An exploratory prospective study.

PURPOSE: To assess female cancer patients' perceptions of the fertility preservation decision-making process and to examine the effect of clinicians' support on the decision quality. METHODS: A total of 71 patients participated in this longitudinal study with two assessment time points (before cancer therapy, after cancer therapy). Self-report measures assessed the decision-making process, the decision quality and the clinicians' support. RESULTS: A less positive experience in the decision-making process was associated with higher decisional regret and lower decisional satisfaction. In the group that decided not to pursue FP, participants who perceived higher oncologist's support reported higher decisional satisfaction. CONCLUSIONS: A higher quality decision is positively associated with a better experience in the decision-making process. The oncologist's support is crucial for the decisional satisfaction of patients who decide not to pursue FP. Implications for psychosocial providers: Psychologists may be important in helping patients to adequately cope with the FP decision so that they can make a high-quality decision.

Triatomine Fauna and Recent Epidemiological Dynamics of Chagas Disease in an Endemic Area of Northeast Brazil.

Updated information of the dispersion dynamics of Chagas disease (CD) and a systemic analysis of these data will aid the early identification of areas that are vulnerable to transmission and enable efficient intervention. This work synthesized spatiotemporal information regarding triatomine fauna and analyzed this information in combination with the results from serological tests to elucidate the epidemiological panorama of CD in the state of Sergipe, Brazil. This is a retrospective analytical study that utilized information from the database of the National Chagas Disease Control Program. Between 2010 and 2016, 838 triatomines of eight species, namely, Panstrongylus geniculatus, which was first recorded in the state of Sergipe, Panstrongylus lutzi, P. megistus, Triatoma brasiliensis, T. pseudomaculata, T. tibiamaculata, T. melanocephala, and Rhodnius neglectus, were collected. Optical microscopy revealed that 13.2% of triatomines examined were infected by Trypanosoma cruzi-like flagellates. The distribution of triatomines exhibits an expanding south-central to northern dispersion, with a preference for semiarid and agreste areas and occasional observations in humid coastal areas due to anthropogenic actions reflected in the environment. Of the human cases analyzed from 2012 to 2016, 8.3% (191/2316) presented positive serology for Trypanosoma cruzi, and this proportion showed a gradual increase in the southern center of the state and new notifications in coastal regions. There is a need for intensification and continuity of the measures adopted by the Chagas Disease Control Program in Sergipe, identifying new priority areas for intervention and preferential ecotopes of the vectors, considering the occurrence of positive triatomines intradomicilliary and a source of new triatomines in the peridomiciles.

Clinical practices among healthcare professionals concerning neonatal jaundice and pale stools.

Jaundice and pale stools are major indicators of neonatal liver disease. Prognosis depends on timely diagnosis and management. We evaluated the clinical practices among healthcare professionals concerning jaundiced newborns and their ability to recognize pale stools. We supplied a questionnaire and a panel with eight photographs of stools, both locally validated, to physicians and nurses of the National Healthcare Service. Analysis was conducted according to professional status, specialization and years of experience of professionals and level of healthcare. Questionnaires were administered to 266 participants (100 physicians, 166 nurses). The decision to send patients to medical observation depended on the intensity of jaundice for a significant percentage of nurses. Concerning jaundiced newborns breastfed and otherwise healthy, 28.9% of physicians would never request a conjugated bilirubin assay, and only 43.3% would request it after 14 days old; for those with other signs/symptoms of disease, only 69.1% of physicians would request it immediately. Multiple linear regression analysis identified specialization as an independent variable significantly associated with the ability to recognize pale stools. CONCLUSION: A significant percentage of healthcare professionals assumed clinical practices that preclude the timely recognition of cholestasis/pale stools, reinforcing the idea of educational needs. Specialization, rather than years of experience of professionals, was associated with better skills and practices. What is Known: • Neonatal cholestasis is a condition with some rare underlying entities having high mortality and morbidity. Early diagnosis is crucial to improve prognosis. Yet, many cases remain late recognized and referred. • Studies evaluating the ability of healthcare professionals to recognize neonatal cholestasis are scarce. What is New: • In this study, a significant percentage of professionals assumed clinical practices that preclude timely recognition of neonatal cholestasis and pale stools, reinforcing the idea of educational needs. • Specialization of professionals was associated with better skills and practices.

Are women and men well informed about fertility? Childbearing intentions, fertility knowledge and information-gathering sources in Portugal.

BACKGROUND: The postponement of parenthood may increase the number of couples experiencing infertility and prolonged time to pregnancy. Previous research has revealed that childless people are not well informed regarding fertility, which may threat their childbearing intentions. This study aimed to examine fertility knowledge and childbearing intentions held by Portuguese people and their use and perceived usefulness of information sources on fertility. METHODS: Participants were recruited using a random-route domiciliary approach. A total of 2404 individuals aged 18-45 were asked to complete a structured questionnaire evaluating socio-demographic characteristics, childbearing intentions, fertility knowledge and information-gathering sources regarding fertility. RESULTS: In total, 95.5% of the participants indicated the desire to have children in the future, and 61.7% reported that having children would contribute to life satisfaction. Most of the participants expressed the desire to have two children in the future. The discrepancy between the numbers of planned and desired children was higher in men, in participants with lower education levels, in professionally active participants and in the unemployed participants. Relationship stability seemed to be more important in influencing childbearing decisions than financial stability or family support. Participants' knowledge regarding fertility was poor. Women, the participants who were older than 25, the participants with longer education and the participants with higher income exhibited the greatest levels of knowledge of fertility, although this knowledge was only slightly enhanced in these subgroups. Also, the participants overestimated both the chances of spontaneous pregnancy and the success rates of assisted reproduction techniques. Finally, the results revealed that websites were the main information sources used by the participants and only 18.0% of the participants had previously discussed fertility issues with their doctors. CONCLUSIONS: Although Portuguese men and women reported the desire to have children in the future, their knowledge regarding fertility and infertility risk was poor. In addition, participants used more general sources of information, such as website, but not specialized sources, such as their doctors. There is a real need to work with general practitioners to empower them to provide adequate fertility information to every childless patient.

Gill parasites of fish from two estuaries in northeastern Brazil: new hosts and geographical records.

Parasites are important components of communities and constitute great part of the biological diversity found in ecosystems, providing valuable information about their hosts and the environment in which they live. However, despite its importance, parasitic diversity is still not well known in some regions of Brazil, especially with respect to fish parasites in the Northeast Region. The present study aims to perform the survey of gill parasites of fish from two tropical estuaries located in northeastern Brazil: Paraíba and Mamanguape rivers. Two collections were made in each estuary, one during the dry period (November / 2013) and the other during the rainy season (July / 2014). The fish were caught using a beach seine net, dragged along the main channel margin. After the identification, biometry and necropsy of the fish, their parasites were collected, stored and identified. For each species of parasite, the values ​​of prevalence, mean intensity and mean abundance were calculated. Of the 882 examined fish, belonging to four species, 145 were parasitized by at least one species of parasite. In total, 18 taxa of parasites of the groups Monogenea, Digenea, Nematoda, Copepoda and Isopoda were recorded, being the copepod Acusicola brasiliensis the most abundant species of parasite.
