RESUMO

Introduction Cancer is a multifactorial disease dependent on the influence of genetic and environmental factors. About 10% of cancers are associated with germline mutations, which predispose to a higher risk of developing cancer. Currently, the use of panels that identify susceptibility and/or association genes cancer has been increasingly used, both in clinical practice and in scientific research. Objective To investigate genetic mutations in patients with a profile for hereditary cancer in individuals from a region of northeast Brazil, where there is a high frequency of endogenous and consanguineous marriages. Methods A set of 17 genes ( BRCA1 , BRCA2 , APC , TP53 , PTEN , RET , VHL , RB1 , CDKN2 , CDH1 , CHEK2 , MLH1 , MSH2 , MSH6 , MUTYH , XPA , and XPC ) associated with cancer and hereditary syndromes were analyzed. Fifteen patients with a hereditary cancer profile were evaluated. Results The pathogenic variant found was c.1187G > A (p.Gly396Asp), rs36053993 in the MUTYH gene in a male patient diagnosed with melanoma at the age of 43 years and a family history for this tumor. This gene encodes an important enzyme related to DNA repair and has been associated with other types of cancer, this is the first report of an association with melanoma, the biological plausibility of this association is given once the MUTYH protein is expressed in the skin tissue and is responsible for repairing damage caused, for example, by sun exposure. Conclusion The results of this study suggest that this mutation may be important for the hereditary predisposition to melanoma, but a broader investigation of this mutation is needed.

RESUMO

Introdução: o plantão psicológico é uma modalidade de atenção psicológica que se caracteriza pela oferta de uma escuta clínica especializada no exato momento em que o sujeito vivencia uma crise. Essa prontidão na acolhida dialoga com as necessidades do sujeito contemporâneo que, imerso num cenário de indisponibilidade de tempo e afeto, encontra no plantão um lugar de referência com o qual poderá contar para o cuidado em saúde mental. Objetivo: analisar a produção científica sobre o plantão psicológico do período de 2017 a 2021. Metodologia: trata-se de um estudo descritivo-exploratório de abordagem quali-quanti acerca das publicações sobre o plantão psicológico indexadas no Portal de Periódicos da CAPES. Resultados: foram encontrados 34 artigos, dos quais 19, por atenderem aos critérios de elegibilidade estabelecidos, integraram este estudo. A produção científica sobre o plantão psicológico vem sendo desenvolvida nos serviços-escola das instituições universitárias, publicadas em veículos de expressiva qualidade, com maior concentração de estudos na região sul do Brasil e com predomínio de pesquisa de natureza qualitativa e relatos de experiência. Em relação à temática abordada, foram identificados três núcleos de sentidos: fundamentação teórica do plantão a partir de uma abordagem específica, plantão como prática clínica na formação profissional em psicologia e características dos sujeitos que demandam a clínica do plantão. Conclusão: constatou-se que os estudos sobre o plantão têm trilhado caminhos diversos, incluindo várias abordagens teóricas e práticas em contextos distintos, com destaque para os serviços-escola das universidades, lugar de concepção dessa modalidade clínica e onde se pode fazer a diferença na formação de profissionais comprometidos ética e politicamente com os sujeitos em situação de angústia/sofrimento psíquico, que têm, no plantão, portas abertas para serem escutados, de modo a compreenderem seus problemas e atribuírem novos significados às suas experiências.


Introduction: the psychological 'on duty' is a type of psychological care that is characterized by the provision of specialized clinical listening, at the exact moment when the subject experiences a crisis. This readiness in welcoming dialogues with the needs of the contemporary subject who, immersed in a scenario of unavailability of time and affection, finds, on duty, a place of reference on which he can count on mental health care. Objective: to analyze the scientific production on psychological duty in the period from 2017 to 2021. Methodology: tis a descriptive-exploratory study with a quali-quanti approach about the publications on psychological duty indexed in the CAPES Journal Portal. Results: a total of 34 articles were found, of which 19, as they met the established eligibility criteria, were part of this study. Scientific production on psychological duty has been developed in the teaching services of university institutions, published in vehicles of expressive quality, with a greater concentration of studies in the southern region of Brazil and with a predominance of qualitative research and experience reports. Regarding the topic addressed, three core meanings were identified: the theoretical foundation of the on-duty from a specific approach, on-duty as clinical practice in professional training in psychology and characteristics of the subjects who demand the on-duty clinic. Conclusion: it was found that studies on the on-duty have followed different paths, including several theoretical and practical approaches, in different contexts, with emphasis on university school services, the place where this clinical modality is conceived and where a difference can be made in training of professionals who are ethically and politically committed to subjects in situations of anguish/psychic suffering, who have, on duty, open doors to be listened to, in order to understand their problems and attribute new meanings to their experiences.

RESUMO

ABSTRACT BACKGROUND: The Hip Sports Activity Scale (HSAS) is a hip-specific instrument for assessing the present levels of physical activity among patients with femoroacetabular impingement (FAI) syndrome. When evaluating treatment outcomes in patients with FAI syndrome, it is necessary to use joint-specific instruments and ones that can evaluate the levels of physical activity in these patients, such as the HSAS-Brazil. OBJECTIVE: To validate the HSAS-Brazil among a group of physically active patients after arthroscopic treatment of FAI syndrome. DESIGN AND SETTING: Cross-sectional research of quantitative and qualitative types using data obtained from July 2018 to October 2019. METHODS: A total of 58 patients of both genders diagnosed with FAI syndrome and who had undergone hip arthroscopy participated in this research. To establish reliability and validity, patients first answered the Brazilian versions of the 12-Item Short-Form Health Survey (SF-12), Nonarthritic Hip Score (NAHS), and HSAS; after a 48-hour interval, they answered the HSAS-Brazil again. RESULTS: For test-retest reliability, the interclass correlation was 0.908 (P < 0.001). The HSAS-Brazil correlated to the NAHS-Brazil (r = 0.63, P < 0.001), as well as the SF-12 (Physical Health) (r = 0.42, P = 0.001). CONCLUSION: The HSAS-Brazil was validated and proved to be a reliable and valid scale to assess sports activity levels in physically active patients with FAI syndrome after arthroscopic treatment.

RESUMO

OBJECTIVE: Chronic Ankle Instability (CAI) or Functional Ankle Instability (FAI) is a condition characterized by laxity and mechanical instability in the ankle joint. This instability interferes with the activities and physical-functional parameters of athletes, which leads to repetitive ankle sprains. The current systematic review was carried out to identify the effects of whole-body vibration exercise (WBVE) in athletes with CAI. METHODS: We conducted electronic searches in Pubmed, the Cochrane Library, Embase, Web of Science, Scopus, Science Direct, Allied Health Literature (CINAHL) and Academic Search Premier (ASP) (EBSCO) databases on 26 February 2022. Registers were identified, and studies were selected for inclusion according to the eligibility criteria. The methodological quality was assessed by the Physiotherapy Evidence Database (PEDro) scale. RESULTS: Seven studies were included with a mean methodological quality score of 5.85, considered 'regular' quality on the PEDro scale. WBVE interventions in athletes with CAI showed that this exercise contributes to a better response on parameters of neuromuscular performance, muscle strength and consequently in balance and postural control, variables that are for the management of CAI. CONCLUSION: WBVE interventions in sports modalities promote physiological responses that may lead to positive effects in several parameters. The protocols proposed in each modality can be carried out in practice and are considered effective additional exercise and training methods beyond traditional types of training for athletes. However, more studies are needed on athletes with this condition, with specific protocols, to highlight the possible physiological and physical-functional responses. Protocol study registration: PROSPERO (CRD42020204434).

RESUMO

BACKGROUND: Food contamination by Staphylococcus spp. enterotoxigenic strains is quite common and despite underreporting caused by the short duration of clinical symptoms and lack of medical care, staphylococcal food poisoning is one of the most common Foodborne Diseases (FBD) in the world. This study describes a systematic review protocol with meta-analysis on the prevalence and types of staphylococcal enterotoxins in food, and the profile of contaminated foods. METHODS: The research will be conducted through the selection of studies reporting the analysis of staphylococcal enterotoxins in food contaminated by Staphylococcus spp. Searches will happen on the following databases: Medline (OVID), GALE, Science Direct, CAB Direct (CABI), Google Scholar, in addition to manual search in the list of references of articles, directory of theses and dissertations, and countries' health agencies. Reports will be imported into the application Rayyan. Two researchers will independently select studies and extract data, and a third reviewer will solve conflicting decisions. The primary outcome will be the identification of staphylococcal enterotoxins in food, and the secondary outcomes will include staphylococcal enterotoxin types and foods involved. To assess the risk of bias in the studies, the tool developed by the Joanna Briggs Institute (JBI) will be used. For data synthesis, a meta-analysis will be performed. However, in case that is not possible, a narrative synthesis of the most relevant results will be carried out. DISCUSSION: This protocol will serve as the basis for a systematic review that aims to relate the results of existing studies on the staphylococcal enterotoxin prevalence and types in food, and the profile of the contaminated foods. The results will broaden the perception of food safety risks, highlight existing literature gaps, contribute to the study of the epidemiological profile and may guide the allocation of health resources for the development of preventive measures related. SYSTEMATIC REVIEW REGISTRATION: PROSPERO registration number: CRD42021258223.

RESUMO

BACKGROUND: Alterations in circadian system organization have been related to major depressive disorder manifestations. This study aimed to evaluate chronobiological parameters, such as sleep, levels of 6-sulfatoxymelatonin, and others derived from actimetry as potential predictors of adequate treatment response in MDD. METHODS: 98 adult women with confirmed diagnosis of MDD were included. Participants completed standard questionnaires (Hamilton Depression Rating Scale - HAM-D; Munich Chronotype Questionnaire - MCTQ) at baseline and after 4 weeks of treatment. Urinary samples for assessing 6-sulfatoxymelatonin were collected on the day before and immediately after pharmacological treatment administration, and 28 continuous days of actigraphy data were collected during the protocol. Participants were classified into Responder (R) or Non-responder (NR) to antidepressant treatment in 4 weeks (early responder), which was characterized by a ≥50 % decrease in the HAM-D score. RESULTS: The following biological rhythms variables significantly predicted a better treatment response in a model controlling for age, sex, and previous treatments: higher levels of activity (M10 - average activity in the 10 most active hours within the 24 h-day) and an earlier center of the 10 most active hours (M10c), as well as lower intradaily variability (IV) of light exposure. Sleep parameters and 6-sulfatoxymelatonin levels did not associate with treatment response prediction. LIMITATION: Actimetry data were not assessed before changing in the treatment plan. CONCLUSION: Different patterns in activity and light exposure might be linked to early antidepressant response.

RESUMO

PURPOSE: Chronic kidney disease (CKD) is a clinical condition that promotes a decline in the overall health status of individuals affected, including parameters physical, functional, and psychosocial. This systematic review was conducted to assess effects of whole-body vibration exercise (WBVE) in individuals with CKD. MATERIALS AND METHODS: It was conducted electronic searches in Pubmed, Embase, Scopus, Web of Science databases on May 2021. Records were identified and irrelevant studies were excluded based in eligibility criteria. RESULTS: Five studies were included with a mean methodological quality score of 9, considered high quality in PEDRo scale. The studies have shown that the WBVE intervention, when applied low intensity was well tolerated, and no adverse effects; was able to improve the motor performance and strength in frail people, which could benefit the prevention of falls events. However, did not improve the quality of life, and the heart rate variability; and not altered cardiorespiratory parameters. CONCLUSIONS: WBVE intervention promotes a better response in parameters of the motor performance and muscular strength, and interaction bone-muscle. Nevertheless, more studies are needed with this intervention to improve physiological responses, and to understand your recommendation to prevent and reduce the complications and symptoms of the CKD, promoting an active life to these patients. PROTOCOL STUDY REGISTRATION: PROSPERO (CRD42020203295).IMPLICATIONS FOR REHABILITATIONChronic kidney disease (CKD) is a clinical condition that promotes a decline in the overall health status of individuals affected, including parameters physical, functional, and psychosocial.WBVE program possibility, of good acceptance, efficient as well tolerated by physically deconditioned patients who present difficulty to perform any type of exercise.WBVE protocol can promote changes in the patient with CKD lifestyle and benefits for this population because is an exercise without fatigue, impact, stress, or discomfort.

RESUMO

Background and Aim: Obliterative portal venopathy (OPV) is one of the causes of non-cirrhotic portal hypertension. However, many aspects of OPV remain unclear, including the etiology, pathogenesis, and natural history. The aim of this study was to describe the clinical features of OPV in a series of patients in Brazil in whom OPV was diagnosed through liver biopsy. Methods: Forty-three consecutive adult patients with OPV were retrospectively selected as a case series based on histologic criteria, defined by the presence of at least portal fibrosis, phlebosclerosis, disappearance and/or reduction of the caliber of portal vein branches, and exclusion of cirrhosis. Clinical and laboratory data were analyzed. Clinically significant portal hypertension was considered in the presence of esophageal varices and/or ascites. Results: The mean age of patients at diagnosis was 44.5 ± 11 years, who were predominantly female (81%). Clinically significant portal hypertension was found in 28% of cases. The most frequent indication for liver biopsy was the elevation of liver enzymes, mostly γ-glutamyl transferase (GGT) in 76% of patients, averaging 222 IU/L (upper limit of normality up to 40 IU/L) and alanine aminotransferase (ALT) in 64%, mean 84 IU/L (38 IU/L). One-third of our patients had exposure to medications, especially herbal medicines, at the time of enzymatic changes. Other risk factors highlighted were features of autoimmunity in 25% of patients or thrombophilia in 20%. Conclusion: OPV can be diagnosed even before the onset of portal hypertension, ALT elevation, and especially GGT elevation in most cases. Its etiology is not defined, but autoimmune diseases, thrombophilia, and the use of medications or herbal medicines may play a role.

RESUMO

AIM: To evaluate the perception of bedside nurses regarding the implementation of solutions proposed by nurse leaders for patient and employee care during the COVID-19 pandemic. BACKGROUND: Nurse leaders have proposed solutions to better manage the challenges of the pandemic. However, multiple factors influence the transposal of actions from the tactical to the operational levels. METHOD: This cross-sectional study was carried out in a 620-bed non-profit institution. Participants were bedside nurses who completed an online survey. RESULTS: One hundred sixty-eight nurses participated in the study. Most of the proposed solutions were very effective and easily identified by the nurses. These solutions included adaptations of the physical structure, availability of medical supplies and adequacy of institutional protocols. The actions that stood out with low perception were adequate integration of new employees and the availability of remote work, hotel accommodations for frontline health care workers and day care for children whose parents worked at the hospital. CONCLUSION: Bedside nurses were able to recognize most of the solutions proposed by their nurse leaders during the COVID-19 pandemic. IMPLICATIONS FOR NURSING MANAGEMENT: Tactical-level nurse leaders need constant proximity to bedside nurses and continuous elucidation of the objectives to be achieved by the strategies adopted.

RESUMO

BACKGROUND: Brazilian spotted fever (BSF), the most lethal tick-borne disease in the Western Hemisphere, is caused by the bacterium Rickettsia rickettsii and transmitted by the bite of Amblyomma sculptum. Capybaras are considered primary hosts of this tick and amplifier hosts of R. rickettsii, generating new infected lineages of A. sculptum in BSF-endemic areas. To define a possible treatment regimen for controlling the tick A. sculptum in capybaras, the aim of this study was to establish an effective fluazuron (FLU) dose to control A. sculptum larvae in artificially infested guinea pigs. METHODS: In Study I (pharmacokinetic and pharmacodynamic analysis), 24 guinea pigs were divided into four equal groups: control group (CG; untreated) and treated groups receiving FLU administered by gavage in three doses: G1-1 mg/kg, G2-5 mg/kg and G3-10 mg/kg, once a day for 15 days (d0 to d + 14). Blood samples were collected from the animals of the treated groups before and at d + 1, + 2, + 4, + 7, + 15 and + 21. The guinea pigs were artificially infested at d + 7 with A. sculptum larvae, and specimens were recovered at d + 11 to d + 14 and kept in a climatized chamber for 14 days. In Study II (evaluation of pharmacokinetic parameters), one group of eight animals received FLU administered by gavage in a single dose of 10 mg/kg, and blood samples were collected before and on day 0 (8 h after treatment), + 1, + 4, + 7, + 15, + 21 and + 28 after single FLU administration. FLU was analyzed in plasma samples by high-performance liquid chromatography with ultraviolet detection. RESULTS: FLU plasma concentrations increased quickly, indicating rapid absorption, and decreased slowly. Some larvae from all treated groups exhibited morphological and behavioral changes. FLU interfered in molting, and the efficacy obtained was 100% for all treated groups. CONCLUSIONS: The results offer promising perspectives for the development of a palatable feed cube containing FLU for free-living capybaras to control A. sculptum and also to prevent BSF in areas where capybaras have been shown to play a primary role.

RESUMO

Polycystic ovary syndrome (PCOS) is the most common endocrine disorder in women associated with cardiovascular disease and obesity. The possible benefits of omega-3 supplementation in this syndrome have been discussed much. This study is aimed to verify, based on the scientific data published, if there are any benefits in the omega-3 supplementation in the treatment of PCOS and to indicate its possible dosages for the treatment of polycystic ovary. The work consists of a systematic review of clinical trials and cohort of the MEDLINE/PubMed database from 2009 to October 2019. All studies that analyzed the omega-3 supplementation in women with PCOS were included. Cross-sectional studies, review articles, systematic reviews, meta-analysis, duplicates, studies in animals or cell culture, studies with omega-3 supplementation via food or associated with other supplementations were not included, except those involving vitamin E. In total, 21 articles were selected. Despite the heterogeneity of the studies selected, indirect benefits were observed mainly regarding the glycemic profile, such as insulin resistance reduction, lipid profile modulation (i.e. decrease in total cholesterol, triglycerides, and elevation of high-density lipoprotein), and the regulation of the androgenic profile. As for the anthropometric profile, the studies were scarce and most of them had no significant meaning. Regarding the antioxidant profile and inflammatory biomarkers, the findings differ among studies, but promising results were observed with different doses over 12 weeks of use, such as C-reactive protein (CRP) reduction. Thus, omega-3 fatty acids promote indirect benefits in the treating of women with PCOS. However, to reveal well-defined standards for dosage and supplementation time, further studies are needed.

RESUMO

Modern lifestyle is characterized by constant exposure to artificial light, which is associated with alterations in biological rhythms, abnormalities to reproductive cycles and metabolic changes. In this study, we aimed to evaluate the effects of four different lighting patterns on puberty timing and on possible metabolic changes in female Wistar rats. Additionally, we developed a machine learning algorithm to automatically classify the stages of the estrous cycle. Adult Wistar rats mated during a week at a photoperiod station where they were exposed to combined red-green-blue lights (RGB) during the photoperiod that varied its spectral composition (i.e., variable color temperature) during the day (RGB-v; N = 14), RGB during the photoperiod with a fixed light color temperature (RGB-f; N = 13) during the whole photoperiod; constant darkness (DD; N = 13) and constant fixed light (LL; N = 15). Experiments were performed only on female litters from postnatal day (PND) 22 to 50. Body weight, puberty onset, estrous cyclicity and serum metabolic parameters were measured. We also collected pictures of vaginal smears to create a dataset of 15,936 images to construct an automatic classifier based on convolutional neural networks. No significant differences were found in the age of vaginal opening; however, the RGB-v group showed a significantly lower number of complete and consecutives cycles. Also, the RGB-f group showed the first complete estrous cycle significantly earlier than the RGB-v group. Female rats housed in LL condition presented significantly lower mean body weight from PND 33 to PDN 47 compared to the other groups. Furthermore, higher levels of plasma triglycerides were found in the DD group compared to RGB-f and RGB-v. HDL levels were significantly lower in RGB-v compared to RGB-f and LL groups. Total cholesterol was significantly lower in RGB-v compared to all groups. Visceral fat was significantly higher in RGB-f compared to the LL group. These results suggest that both changes in photoperiod and lighting quality affect pubertal development and alter lipid profiles and visceral fat accumulation.

RESUMO

Background and Purpose: The development of quality and safety competencies is an important issue in nursing education globally. The purpose of this study was to cross-culturally adapt the Quality and Safety Education for Nurses Student Evaluation Survey (QSEN SES) for use in Brazil and evaluate its psychometric properties. Methods: The QSEN SES was adapted into Brazilian Portuguese. Reliability and structural validity were evaluated in an online study with 130 undergraduate nursing students. Results: The content validity index (CVI) of the instrument was 0.93. The reliability was strong. Confirmatory factor analysis was conducted, and the model fit was insufficient. Conclusions: The Brazilian version of QSEN SES is reliable, but additional analyses are needed with a larger sample to confirm the construct validity of the instrument.

RESUMO

The essential oils (EOs) of Illicium verum and Pelargonium graveolens were evaluated for lethality, inhibition of development and residual efficacy against the flea Ctenocephalides felis felis. Their chemical composition was characterized by means of gas chromatography with a flame ionization and mass spectrometry detection. Mortality at different immature stages and among adult fleas was measured through in vitro filter paper tests at different concentrations of EOs. The chemical characterization of I. verum volatile oil showed that E-anethole (79.96%) was the major constituent, while the major compounds in P. graveolens were citronellol (29.67%) and geraniol (14.85%). Insecticidal activity against both immature and adult flea stages were observed. The EO of I. verum had insecticidal activity for approximately 18 days, while the EO activity of P. graveolens lasted for 13 days. The pulicidal activity of I. verum remained above 70% for up to 9 days, while the activity of P. graveolens was 41.7% for up to 2 days. Essential oils, especially that of I. verum, showed insecticidal activity for flea control at different life cycle stages and have potential for the development of ectoparasiticides (biopesticides) for veterinary use.

RESUMO

The advent of immune-checkpoint inhibitors (ICI) in modern oncology has significantly improved survival in several cancer settings. A subgroup of women with breast cancer (BC) has immunogenic infiltration of lymphocytes with expression of programmed death-ligand 1 (PD-L1). These patients may potentially benefit from ICI targeting the programmed death 1 (PD-1)/PD-L1 signaling axis. The use of tumor-infiltrating lymphocytes (TILs) as predictive and prognostic biomarkers has been under intense examination. Emerging data suggest that TILs are associated with response to both cytotoxic treatments and immunotherapy, particularly for patients with triple-negative BC. In this review from The International Immuno-Oncology Biomarker Working Group, we discuss (a) the biological understanding of TILs, (b) their analytical and clinical validity and efforts toward the clinical utility in BC, and (c) the current status of PD-L1 and TIL testing across different continents, including experiences from low-to-middle-income countries, incorporating also the view of a patient advocate. This information will help set the stage for future approaches to optimize the understanding and clinical utilization of TIL analysis in patients with BC.

RESUMO

RESUMO Fases líquidas não aquosas leves (LNAPL), como combustíveis líquidos, estão presentes em muitas áreas contaminadas. Para o gerenciamento dessas áreas, é importante conhecer a mobilidade desse produto, a fim de subsidiar decisões sobre sistemas de remediação e avaliação de risco. Uma alternativa para quantificar a mobilidade é o parâmetro transmissividade de LNAPL, ainda pouco aplicado no Brasil. Esse trabalho avaliou a aplicabilidade desse parâmetro em diferentes áreas contaminadas por LNAPL. Foram realizados testes em três áreas com litologias, tipos de contaminantes e históricos de contaminação distintos. Em alguns testes, não foi possível determinar a transmissividade de LNAPL devido à instabilidade do nível de fluidos, por consequência da operação de sistemas de bombeamento e precipitação, além de problemas operacionais durante a realização do teste. Apesar de ser um teste simples, em alguns casos, a determinação de transmissividade de LNAPL pode ser inviável, principalmente para LNAPL de baixa mobilidade por requerer testes mais prolongados. Os principais fatores determinantes no valor de transmissividade de LNAPL foram a litologia, a posição do poço na pluma e a posição do nível d'água em relação a série histórica. Assim, a transmissividade de LNAPL pode ser um parâmetro útil no gerenciamento de áreas contaminadas, cuja interpretação deve ser feita de forma cautelosa e integrada com outros dados de investigação da área.


ABSTRACT Light non-aqueous phase liquids (LNAPL), such as liquid fuels, are present in many contaminated sites. To adequately manage these sites, it is important to know the product mobility, to support decisions on remediation systems and risk assessment. One alternative to quantify mobility is to quantify the LNAPL transmissivity, which is rarely applied in Brazil. This work aimed to evaluate the applicability of this parameter in LNAPL contaminated sites with different conditions. Tests were performed in three sites, with different lithologies, types of contaminants and contamination histories. In some tests, it was not possible to obtain representative values of LNAPL transmissivity due to fluids levels instability, caused by pumping systems and precipitation events, and operational problems during the tests. Despite being a simple test, in some cases, the determination of LNAPL transmissivity may not be feasible, especially for low mobility LNAPLs, that require long period tests. The main factors controlling LNAPL transmissivity values were lithology, position of the well in the plume, and water level elevation in relation to the historical series. Thus, LNAPL transmissivity can be a useful parameter in the management of contaminated sites, but its interpretation must be made cautiously and integrated with other site data.
