Qualitative Evaluation of Paraspinal Musculature After Minimally Invasive Lumbar Decompression: A Prospective Study.

BACKGROUND: To quantify fatty infiltration and degree of paraspinal muscle degeneration in patients submitted to tubular microdiscectomy and conventional open microdiscectomy. METHODS: A prospective cohort of patients was submitted to microdiscectomy for lumbar disc herniation after failure of conservative treatment. Selection of the technique was based on the surgeon's preference. Analysis of the multifidus muscle was performed using the Goutallier system and the percentage of fat in the muscle. Preoperative and 1-year postoperative T2-weighted magnetic resonance imaging was used, and statistical analysis was carried out using the Wilcoxon test and Spearman correlation test using a significance level of 5%. RESULTS: Thirty-two patients were included in the study. The percentage of fatty infiltration in the muscle increased on both sides of the spine 1 year after surgery, although only the ipsilateral side presented statistical significance in patients submitted to conventional microdiscectomy (43.3% preoperative and 57.8% postoperative). Muscular degeneration increased significantly ipsilateral to the disc herniation according to the Goutallier classification (grades 1-2) for both interventions. No statistically significant difference was found for fatty infiltration scores or for the degree of muscular degeneration of the multifidus in the comparative analysis of the methods. CONCLUSIONS: Muscular damage resulting from surgery of lumbar disc herniation significantly increases fatty infiltration and degeneration of the multifidus. Muscular degeneration was associated with worsening back pain. CLINICAL RELEVANCE: While no significant difference was found between the techniques, the tubular minimally invasive approach shows a tendency for less muscle damage. These findings highlight the importance of minimizing muscle injury during surgery to improve postoperative recovery and long-term outcomes.

Diagnostic MRI Score to Differentiate Susac Syndrome from Primary Angiitis of the Central Nervous System and Multiple Sclerosis.

OBJECTIVE: Susac syndrome (SuS), multiple sclerosis (MS), and primary angiitis of the central nervous system (PACNS) present diagnostic challenges due to overlapping clinical features. We aimed to enhance diagnostic precision by developing the SPAMS (SuS, PACNS, MS) score, a practical radiological tool. METHODS: This multicenter study included 99 patients (43 SuS, 37 MS, 19 PACNS) from South American countries. Relevant MRI features were identified through an elastic-net model determined key variables. RESULTS: The SPAMS score assigned 2 points for snowball lesions, 1 point for spokes-like lesions, or if there are more than 4 lesions in the corpus callosum, corpus callosum involvement, or cerebellar involvement. It subtracted 1 point if gadolinium-enhancing lesions or 4 points if Dawson's fingers are present. Bootstrapping validated the optimal cutoff at 2 points, exhibiting a diagnostic performance of area under the curve = 0.931, sensitivity = 88%, specificity = 89%, positive predictive value = 88%, negative predictive value = 89%, and accuracy = 88%. INTERPRETATION: When specific MRI findings coexisted, the SPAMS score differentiated SuS from MS and PACNS. Access to MRI and standard protocol sequences makes it a valuable tool for timely diagnosis and treatment, potentially preventing disability progression and severe clinical outcomes.

ACE I/D polymorphism is a risk factor for the clinical severity of COVID-19 in Brazilian male patients.

BACKGROUND: The renin-angiotensin system is potentially involved in the pathogen-host interaction in the disease caused by SARS-CoV-2, since the angiotensin-converting enzyme (ACE) 2 serves as a receptor for the virus. The impact of the pandemic in specific regions and ethnic groups highlights the importance of investigating genetic factors that disrupt the balance of the system in response to SARS-CoV-2 infection, especially in genes with ethnic frequency variations. Therefore, this study aimed to evaluate the influence of the ACE I/D polymorphism on the incidence and severity of COVID-19 in a sample of the Brazilian population. METHODS AND RESULTS: 70 severe cases and 355 mild cases patients were evaluated. DNA extraction was performed using a QIAamp DNA Blood Mini kit. Genotyping of ACE I/D polymorphism was performed. Clinical outcomes were obtained from the patients' records. We found an association between the ACE I/D polymorphism and the incidence or severity of COVID-19 in male participants. Moreover, we observed a relationship between severity and increasing age and body weight and a higher frequency of II genotype individuals among those who had a cough as their symptoms in mild patients. No differences were observed in leukocyte count or other parameters related to the inflammatory response in severe patients. CONCLUSIONS: Our data showed the influence of the ACE I/D polymorphism on severity of COVID-19 in males, as well as on the occurrence of cough in patients with mild symptoms, with a higher incidence in those carrying the I allele.

Prevalence and impact of comorbidities in women with chronic pelvic pain / Prevalência e impacto de comorbidades em mulheres com dor pélvica crônica

ABSTRACT BACKGROUND AND OBJECTIVES: Chronic pelvic pain (CPP) is a common condition in women and there are often associated comorbidities. The objective of this study was to evaluate the prevalence of comorbidities in patients with CPP and to seek associations between comorbidities and the manifestations of chronic pain. METHODS: Observational case-control study with sociodemographic, behavioral and clinical information, including comorbidities, in 246 women, 123 with CPP and 123 without CPP (control group). RESULTS: Anxiety, depression, migraine and endometriosis were the most frequent comorbidities in women with CPP. The comorbidities assessed in the CPP group were not associated with pain intensity score, history of abortion, physical violence or sexual violence (p>0.05). In the group of women with CPP and endometriosis, the median anxiety and depression score was significantly lower than in the group without endometriosis (14.5; 95% CI: 11.0-14.9) versus (17.0; 95% CI: 14.6-16.7), p=0.012 and (13.0; 95%CI: 11.1-15.9) versus (16.5; 95% CI: 14.5-17.6), p= 0.045, respectively. In patients with migraine, the median depression score was higher in the group of women with CPP compared to the group without CPP (15.0; 95% CI: 14.1-17.8) versus (10.0; 95% CI: 8.5-12.4), p=0.048. CONCLUSION: The most prevalent comorbidities in women with CPP were mental disorders, migraine and endometriosis. Comorbidities were not related to pain intensity, physical violence or sexual violence. Having a diagnosis of endometriosis is associated with lower anxiety and depression scores in patients with CPP. Overlapping migraine and CPP were associated with a worse depression score.

RESUMO JUSTIFICATIVA E OBJETIVOS: A dor pélvica crônica (DPC) é uma condição comum em mulheres e frequentemente há comorbidades associadas. O objetivo deste estudo foi avaliar a prevalência de comorbidades em pacientes de DPC e buscar associações entre comorbidades e as manifestações da dor crônica. MÉTODOS: Estudo observacional de caso-controle com informações sociodemográficas, comportamentais e clínicas, incluindo comorbidades, em 246 mulheres, sendo 123 com DPC e 123 sem DPC (grupo controle). RESULTADOS: Ansiedade, depressão, enxaqueca e endometriose foram as comorbidades mais frequentes em mulheres com DPC. As comorbidades avaliadas no grupo com DPC não se associaram com o escore de intensidade da dor, com história de aborto, de violência física nem de violência sexual (p>0,05). No grupo de mulheres com DPC e endometriose, a mediana do escore de ansiedade e de depressão foi significativamente menor do que no grupo sem endometriose (14,5; IC 95%: 11,0-14,9) versus (17,0; IC 95%: 14,6-16,7), p=0,012 e (13,0; IC 95%: 11,1-15,9) versus (16,5; IC 95%: 14,5-17,6), p=0,045, respectivamente. Em pacientes com enxaqueca, a mediana do escore de depressão foi maior no grupo de mulheres com DPC em relação ao grupo sem DPC (15,0; IC 95%: 14,1-17,8) versus (10,0; IC 95%: 8,5-12,4), p=0,048. CONCLUSÃO: As comorbidades mais prevalentes em mulheres com DPC foram transtornos mentais, enxaqueca e endometriose. As comorbidades não se associaram à intensidade da dor, violência física ou sexual. O diagnóstico de endometriose associou-se a menores escores de ansiedade e de depressão em mulheres com DPC. A sobreposição de enxaqueca e DPC associou-se a um pior escore de depressão.

Evaluation of unilateral corneal collagen cross-linking on fellow untreated eyes of patients with keratoconus / A avaliação da reticulação unilateral do colágeno corneano em olhos não tratados de pacientes com ceratocone

ABSTRACT Purpose: This study aimed to examine the effects of unilateral corneal collagen cross-linking treatment on visual acuity and the topographic findings of the fellow untreated eye of patients who had bilateral progressive keratoconus. Methods: Patients with progressive keratoconus who underwent cross-linking treatment were screened retrospectively. A total of 188 untreated eyes of 188 patients whose eyes were treated unilaterally with either standard or accelerated cross-linking and refused cross-linking procedure for the fellow eye were included. Visual acuity and topographic findings of the fellow untreated eyes were obtained preoperatively and postoperatively at the 1st, 3rd, 6th, 12th, 24th, 30th, and 36th months. Results: The change over time of variables examined was similar in the untreated eyes of patients who received standard and accelerated cross-linking methods (p>0.05). At the 12th month, 136 (95.8%) untreated eyes were stable according to progression criteria. Only 4 (8%) eyes were progressive at the 24th month. No progression was observed in any of the 16 patients with a 36-month follow up. Conclusions: The results showed that the fellow untreated eyes of patients with bilateral progressive keratoconus did not have significant progression rates after unilateral cross-linking treatment.

RESUMO Objetivo: Examinar os efeitos do tratamento de reticulação unilateral do colágeno corneano na acuidade visual e os achados topográficos em olhos não tratados de pacientes com ceratocone progressivo bilateral. Métodos: Foram rastreados retrospectivamente pacientes com ceratocone progressivo submetidos a tratamento de reticulação. Foram incluídos no estudo 188 olhos não tratados de 188 pacientes tratado unilateralmente com reticulação padrão ou acelerada e que recusaram o procedimento de reticulação no outro olho. A acuidade visual e os achados topográficos dos olhos não tratados foram obtidos no pré- e pós-operatório no 1º, 3º, 6º, 12º, 24º, 30º e 36º mês. Resultados: As alterações ao longo do tempo foram semelhantes para as variáveis examinadas nos olhos não tratados de pacientes tratados com métodos de reticulação padrão e acelerado (p>0,05). No 12º mês, 136 olhos não tratados (95,8%) estavam estáveis, de acordo com os critérios de progressão. Apenas quatro olhos (8%) mostraram progressão no 24º mês. Nenhuma progressão foi observada nos 16 pacientes que tiveram um acompanhamento de 36 meses. Conclusões: O estudo mostrou que os olhos não tratados de pacientes com ceratocone progressivo bilateral não apresentaram taxas de progressão significativas após o tratamento unilateral com reticulação.

Abstract Objective To understand the meaning of chronic pelvic pain from the perspective of diagnosed women and analyze the determining factors for outpatient discharge. Methods This is qualitative research, using strategic social research as its theoretical methodological framework. 14 women participated in the study, seven of whom were undergoing outpatient follow-up and seven who were discharged from the gynecology outpatient clinic of a university hospital in the city of Goiânia, Goiás, Brazil. Semi-structured interviews were carried out with guiding questions. The analysis of results was based on the thematic modality of content analysis, according to Bardin. Results Data analysis culminated in three thematic categories: "Before the pain", "Living with the pain" and "Treating the pain". Parental emotional abandonment, grief, disagreement with parents and childhood difficulties were prominent before the onset of pain. The onset of pain was related to the birth of children, menarche, surgeries and family conflicts. Living with pain promoted great suffering, fear, harm to relationships and work activity. The improvement in emotional state and financial conditions, the resolution of marital conflicts, the opportunity to express oneself and talk to other patients, the use of medication and some surgical procedures were decisive for pain control and outpatient discharge. Conclusion Chronic pelvic pain was related to socioeconomic, emotional and physical suffering. The resolution of these aspects contributed to outpatient discharge.

In vivo localization of occult lesions and margins in breast carcinoma using radio-fluorescence: a new hybrid technique

Objective: The aim of this study was to present a new technique for hybrid marking of non-palpable breast lesions and in vivo evaluation of surgical margins, called Fluorescence and Seed for Hybrid Intraoperative Evaluation. Methods: Seven women with non-palpable breast lesions and suspected or confirmed malignancy underwent prior iodine-125 seed implantation and peripheral intravenous administration of indocyanine green 30 min before surgery. A hybrid gamma probe with an optonuclear probe was used to detect gamma radiation in the lesions and, sequentially, the fluorescence mode, in the same lesion and its margins, after its removal. Results: This method distinguished, in real time, one benign and six malignant lesions, guiding the removal, identifying the remaining neoplastic area in the surgical bed, and allowing its intraoperative enlargement. Conclusion: This pilot study evaluates the feasibility of this new technique in identifying the primary lesion and controlling surgical margins using hybrid technology. (AU)

Genotyping Analysis of Cryptococcus deuterogattii and Correlation with Virulence Factors and Antifungal Susceptibility by the Clinical and Laboratory Standards Institute and the European Committee on Antifungal Susceptibility Testing Methods.

Data about the relationship between their molecular types, virulence factors, clinical presentation, antifungal susceptibility profile, and outcome are still limited for Cryptococcus deuterogattii. This study aimed to evaluate the molecular and phenotypic characteristics of 24 C. deuterogattii isolates from the southeast region of Brazil. The molecular characterization was performed by multilocus sequence typing (MLST). The antifungal susceptibility profile was obtained according to CLSI-M27-A3 and EUCAST-EDef 7.1 methods. The virulence factors were evaluated using classic techniques. The isolates were divided into four populations. The molecular analysis suggests recombinant events in most of the groups evaluated. Resistance and susceptibility dose-dependent to fluconazole were evidenced in four isolates (16%) by EUCAST and in four isolates (16%) by CLSI methods. The agreement at ±two dilutions for both methods was 100% for itraconazole, ketoconazole, and voriconazole, 96% for amphotericin B, and 92% for fluconazole. Significant differences in virulence factor expression and antifungal susceptibility to itraconazole and amphotericin B were found. The mixed infection could be suggested by the presence of variable sequence types, differences in virulence factor production, and decreased antifungal susceptibility in two isolates from the same patient. The data presented herein corroborate previous reports about the molecular diversity of C. deuterogattii around the world.

Metal exposure in a child population after a mine tailings dam failure. Projeto Bruminha.

OBJECTIVE: This study aimed to analyze the urinary concentrations of As, Cd, Pb, Hg, and Mn in children living in areas directly affected by the tailings of the Brumadinho disaster. METHODS: We performed a cross-sectional descriptive study on a population of 217 children aged 0 to 6 years, living in Córrego do Feijão (CF), Parque da Cachoeira (PC), Aranha (AR), and Tejuco (TJ), enrolled in the Longitudinal Study of Child Health in Brumadinho (Minas Gerais) - Projeto Bruminha. Socioeconomic data and urine samples were collected to determine the concentration of selected metals. RESULTS: Children living in locations not directly affected by the disaster (AR and TJ) had higher concentrations of As and Mn than those in directly affected areas (CF and PC). Additionally, children living in locations not potentially exposed to dust from tailings mud or mining activity (AR) showed higher urinary As concentrations than those potentially exposed (CF, PC, and TJ). CONCLUSION: Our results suggest the need to investigate possible sources of As exposure in children living in areas not directly affected by the disaster and not potentially exposed to dust.

Sports practice after lumbar discectomy in non-professional athletes: a cross-sectional study / Prática esportiva após discectomia lombar em atletas não profissionais: estudo transversal / Práctica deportiva tras discectomía lumbar en atletas no profesionales: un estudio transversal

ABSTRACT: Introduction: Most athletes treated for lumbar disc herniation return to play between 3 and 9 months after conservative or surgical treatment. In the last two decades, the general population increased the practice and participation in amateur competitions, being more prone to overload injuries. Objectives: To evaluate sports practice after lumbar discectomy in non-professional athletes. Methods: In the last five years, a digital questionnaire was sent to patients submitted to up to two levels of open discectomy. After signing the informed consent form, the patients were instructed to answer the questionnaire with personal and clinical data related to disc treatment and sports practice after the procedure. Results: Of 182 contacted patients, a hundred answered the questionnaire; 65% practiced regular sports activities before surgery. From patients who practiced sports before surgery, 75.38% returned to sports activities after the procedure. 39.29% returned between 3 and 6 months. Only 12.31% referred to impaired sports performance, while 56.92% performed unaffected, and 21.54% reported improved performance after surgery. Prior sports practice, participation in amateur competitions, and regular core strengthening were significantly associated with sports practice after surgery (P<0,05). Conclusions: From the participants who had already practiced sports before surgery, 75.38% returned after the surgical procedure. Sports practice before surgery, participation in amateur competitions, and regular core strengthening were positively associated with a return to sports practice after lumbar discectomy. The study shows that core strengthening should be encouraged and recommended to all non-professional athletes who intend to return to sports after microdiscectomy surgeries. Level of Evidence: III; Cross-Sectional Retrospective Study.

RESUMO: Introdução: A maioria dos atletas tratados de hérnia de disco lombar volta a jogar em um período entre 3 e 9 meses, após tratamento conservador ou cirúrgico. Nas últimas duas décadas, a população em geral aumentou a prática e participação em competições amadoras; sendo mais propenso a lesões por uso excessivo. Objetivos: Avaliar a prática esportiva após discectomia lombar em atletas não profissionais. Métodos: Um questionário digital foi enviado aos pacientes submetidos à discectomia aberta de até 2 níveis, nos últimos cinco anos. Após a assinatura do termo de consentimento livre e esclarecido, os pacientes foram orientados a responder o questionário com dados pessoais e clínicos relacionados ao tratamento e à prática esportiva após o procedimento. Resultados: Dos 182 pacientes contatados, cem responderam ao questionário; destes, 65% praticavam atividades esportivas regulares antes da cirurgia. Dos pacientes que praticavam esportes antes da cirurgia, 75,38% retornaram à atividade esportiva após o procedimento. 39,29% retornaram entre 3 e 6 meses. Apenas 12,31% relataram piora no desempenho esportivo, enquanto para 56,92% o desempenho não foi afetado e 21,54% relataram melhora no desempenho após a cirurgia. A prática esportiva prévia, a participação em competições amadoras e o fortalecimento regular do core foram significativamente associados à prática esportiva após a cirurgia (P<0,05). Conclusões: Dos participantes que já praticavam esportes antes da cirurgia, 75,38% retornaram após o procedimento cirúrgico. A prática esportiva prévia à cirurgia, a participação em competições amadoras e o fortalecimento regular do core foram positivamente associados ao retorno à prática esportiva após a discectomia lombar. O estudo mostra que o fortalecimento do core deve ser incentivado e recomendado para todos os atletas não profissionais que pretendem retornar ao esporte após cirurgias de microdiscectomia. Nível de Evidência III; Estudio Transversal Retrospectivo.

Prevalence of metal levels above the reference values in a municipality affected by the collapse of a mining tailings dam: Brumadinho Health Project.

OBJECTIVE: To describe the prevalence of levels of arsenic, cadmium, mercury, lead and manganese above the reference values (RV) in the population of Brumadinho, after the rupture of the mining tailings dam and to verify the factors associated with these levels. METHODS: Baseline study of a prospective cohort, in a representative sample of 3,080 residents (aged 12 and over) in Brumadinho, Minas Gerais. Exploratory variables (age, sex, skin color, household income, smoking and place of residence) were collected using a questionnaire and the levels of As, Cd and Hg in urine and Pb and Mn in blood were evaluated using the technique of inductively coupled plasma mass spectrometry. The distribution of prevalence of levels above the reference for metals was made, according to the exploratory variables. Multiple logistic regression analyzes were used to investigate the association between altered levels of metals and characteristics evaluated. RESULTS: Concentrations above RV were found in 38.08% of the population for Mn, 33.37% for As, 5.04% for Pb, 0.76% for Hg and 0.17% for Cd. There was a significant association between age group and levels of Mn and Pb; and between place of residence and As level. CONCLUSION: The results show a high prevalence of levels above the reference for Mn, As and Pb, with small differences in relation to the other variables, suggesting that it is an exposure distributed throughout the municipality.

Parenting Styles, Mental Health, and Catastrophizing in Women with Chronic Pelvic Pain: A Case-Control Study.

Chronic pelvic pain (CPP) in women is a highly prevalent condition worldwide and requires multimodal treatment. Adverse childhood experiences have been associated with CPP in women, while allodynia and poor outcomes have been linked to pain catastrophizing in these patients. Pain perception has been associated with parenting style during childhood. The objective of this study was to investigate the association between parenting style, pain catastrophizing, anxiety, depression and CPP in women. A case-control study was conducted between May 2018 and August 2021 with 123 women with CPP and 123 pain-free controls. Questionnaires were used to collect participants' data. The association between parenting style and CPP was assessed using multiple logistic regression, with odds ratios (OR) and 95% confidence intervals (CI) being calculated. The correlation between catastrophizing, pain intensity, pain duration, anxiety, depression, and parenting style in women with CPP was assessed using Spearman's rank correlation coefficient (r). A higher frequency of low maternal care (60.7% versus 45.2%; p = 0.026), anxiety (79.7% versus 56.9%; p < 0.001), depression (73.2% versus 56.1%; p = 0.008) and physical violence (31.7% versus 14.6%; p = 0.003) was found in the CPP group compared to the controls. There was no association between parenting style and CPP in the adjusted analysis. A positive correlation was found between catastrophizing and pain intensity (r = 0.342; p < 0.001), anxiety (r = 0.271; p = 0.002), depression (r = 0.272; p = 0.002), and maternal overprotection (r = 0.185; p = 0.046). A negative correlation was found between anxiety and maternal (r = -0.184; p = 0.047) and paternal (r = -0.286; p = 0.006) care and between depression and maternal (r = -0.219; p = 0.018) and paternal (r = -0.234; p = 0.026) care. The present results suggest a significant but weak association of parenting style with pain catastrophizing, the mental health of women with CPP, and the way in which they experience pain.

The First Report and Phylogenetic Analysis of Canine Distemper Virus in Cerdocyon thous from Colombia.

Canine distemper virus (CDV) is the etiological agent of a highly prevalent viral infectious disease of domestic and wild carnivores. This virus poses a conservation threat to endangered species worldwide due to its ability to jump between multiple species and produce a disease, which is most often fatal. Although CDV infection has been regularly diagnosed in Colombian wildlife, to date the molecular identity of circulating CDV lineages is currently unknown. Our aim was to evaluate the presence and phylogenetic characterization of CDV detected in samples from naturally infected Cerdocyon thous from Colombia. We sequenced for the first time the CDV infecting wildlife in Colombia and demonstrated the presence of South America/North America-4 Lineage with a higher relationship to sequences previously reported from domestic and wild fauna belonging to the United States of America. Our results are crucial for the understanding of the interspecies transmission of CDV in the domestic/wild interface and for the prevention and control of such an important multi-host pathogen.

Quality assessment of systematic reviews of surgical treatment of cervical spine degenerative diseases: an overview.

OBJECTIVE: To gather all systematic reviews of surgical treatment of degenerative cervical diseases and assess their quality, conclusions and outcomes. METHODS: A literature search for systematic reviews of surgical treatment of degenerative cervical diseases was conducted. Studies should have at least one surgical procedure as an intervention. Included studies were assessed for quality through Preferred Reporting Items for Systematic Review and Meta-analysis (PRISMA) and Assessment of Multiple Systematic Reviews (AMSTAR) questionnaires. Quality of studies was rated accordingly to their final score as very poor (<30%), poor (30%-50%), fair (50%-70%), good (70%-90%), and excellent (>90%). If an article reported a conclusion addressing its primary objective with supportive statistical evidence for it, they were deemed to have an evidence-based conclusion. RESULTS: A total of 65 systematic reviews were included. According to AMSTAR and PRISMA, 1.5% to 6.2% of studies were rated as excellent, while good studies counted for 21.5% to 47.7%. According to AMSTAR, most studies were of fair quality (46.2%), and 6.2% of very poor quality. Mean PRISMA score was 70.2%, meaning studies of good quality. For both tools, performing a meta-analysis significantly increased studies scores and quality. Cervical spondylosis studies reached highest scores among diseases analyzed. Authors stated conclusions for interventions compared in 70.7% of studies, and only two of them were not supported by statistical evidence. CONCLUSION: Systematic reviews of surgical treatment of cervical degenerative diseases present "fair" to "good" quality in their majority, and most of the reported conclusions are supported by statistical evidence. Including a meta-analysis significantly increases the quality of a systematic review.

Current Challenges in the Management of Chronic Pelvic Pain in Women: From Bench to Bedside.

Chronic pelvic pain (CPP) affects a significant proportion of women worldwide And has a negative impact on several aspects of these women's lives including mental health, work, relationships and sexual function, among others. This set of factors ultimately reflects negatively on quality Of life. The physiopathology of CPP is complex and remains to be fully clarified; however, recent advances have increased understanding of the mechanisms involved in chronic pain in general, and more specifically, CPP. Nonetheless, even when a detailed clinical history is obtained, meticulous physical examination is performed and imaging resources are appropriately used, the organic cause of the pain may still fail to be identified in a substantial number of women with CPP. Management of CPP may therefore be challenging. This narrative review was aimed at adding to the available literature on the subject, presenting and discussing the principal characteristics of CPP in women. The paper highlights gaps in the literature while providing the most up-to-date evidence associated with the physiopathology and classification of pain, its diagnosis and treatment. In addition, current challenges in the management of women with CPP are discussed.

Prevalence of metal levels above the reference values in a municipality affected by the collapse of a mining tailings dam: Brumadinho Health Project / Prevalência dos níveis de metais acima dos valores de referência em município atingido pelo rompimento de barragem de rejeitos da mineração: Projeto Saúde Brumadinho

ABSTRACT Objective: To describe the prevalence of levels of arsenic, cadmium, mercury, lead and manganese above the reference values (RV) in the population of Brumadinho, after the rupture of the mining tailings dam and to verify the factors associated with these levels. Methods: Baseline study of a prospective cohort, in a representative sample of 3,080 residents (aged 12 and over) in Brumadinho, Minas Gerais. Exploratory variables (age, sex, skin color, household income, smoking and place of residence) were collected using a questionnaire and the levels of As, Cd and Hg in urine and Pb and Mn in blood were evaluated using the technique of inductively coupled plasma mass spectrometry. The distribution of prevalence of levels above the reference for metals was made, according to the exploratory variables. Multiple logistic regression analyzes were used to investigate the association between altered levels of metals and characteristics evaluated. Results: Concentrations above RV were found in 38.08% of the population for Mn, 33.37% for As, 5.04% for Pb, 0.76% for Hg and 0.17% for Cd. There was a significant association between age group and levels of Mn and Pb; and between place of residence and As level. Conclusion: The results show a high prevalence of levels above the reference for Mn, As and Pb, with small differences in relation to the other variables, suggesting that it is an exposure distributed throughout the municipality.

RESUMO Objetivo: Descrever a prevalência dos níveis dos metais arsênio, cádmio, mercúrio, chumbo e manganês acima dos valores de referência (VR) na população de Brumadinho, após o rompimento da barragem de rejeitos de mineração, e verificar os fatores associados a esses níveis. Métodos: Estudo da linha de base de uma coorte prospectiva, em amostra representativa de 3.080 residentes (12 anos ou mais de idade) de Brumadinho, Minas Gerais. As variáveis exploratórias (idade, sexo, cor de pele, renda domiciliar, tabagismo e local de residência) foram coletadas por questionário, e os níveis de As, Cd e Hg na urina e de Pb e Mn no sangue foram avaliados pela técnica de espectrometria de massa com plasma indutivamente acoplado. Fez-se a distribuição das prevalências de níveis acima da referência para os metais, segundo as variáveis exploratórias. Análises de regressão logística múltipla foram utilizadas para averiguar associação entre os níveis alterados de metais e as características avaliadas. Resultados: Encontraram-se concentrações acima do VR em 38,08% da população para Mn, 33,37% para As, 5,04% para Pb, 0,76% para Hg e 0,17% para Cd. Houve associação significativa entre a faixa etária e os níveis de Mn e Pb; e entre o local de residência e o nível de As. Conclusão: Os resultados demonstram elevada prevalência de níveis acima da referência para Mn, As e Pb, com pequenas diferenças em relação às demais variáveis, sugerindo se tratar de uma exposição distribuída em todo o município.
