Severe acute respiratory syndrome coronavirus 2 seroprevalence among patients with pulmonary tuberculosis

SUMMARY OBJECTIVE: The objective of this study was to estimate the seroprevalence of severe acute respiratory syndrome coronavirus 2 antibodies in patients with tuberculosis. METHODS: This cross-sectional study was conducted at an outpatient tuberculosis clinic in Alvorada, RS, Brazil, with data collection between October and December 2020. Outpatients aged>18 years with active pulmonary tuberculosis, no prior history of coronavirus disease 2019, and no suspected coronavirus disease 2019 were included in the study. Whole blood samples were collected to perform the severe acute respiratory syndrome coronavirus 2 antibodies test. RESULTS: During the study period, 52 patients met the inclusion and were included in the analysis. Severe acute respiratory syndrome coronavirus 2 antibodies were positive in 16 (30.8%) patients. Male sex was more frequent among patients with negative severe acute respiratory syndrome coronavirus 2 antibodies than in patients with positive severe acute respiratory syndrome coronavirus 2 antibodies (86.1 vs. 56.3%, p=0.031). Contact with coronavirus disease 2019 case was more common in patients with positive severe acute respiratory syndrome coronavirus 2 antibodies compared with patients with negative severe acute respiratory syndrome coronavirus 2 antibodies (87.5 vs. 8.3%, p<0.0001). In a multivariate analysis, in a model including the variables such as male sex and contact with coronavirus disease 2019 case, only contact with coronavirus disease 2019 was independently associated with positive severe acute respiratory syndrome coronavirus 2 antibodies (OR 77.0, 95%CI 11.5-512.4, p<0.0001). CONCLUSION: This study revealed a seroprevalence of 30.8% severe acute respiratory syndrome coronavirus 2 among patients with tuberculosis.

Effectiveness of perioperative family-centered educational interventions in the anxiety, pain and behaviors of children/adolescents and their parents: Systematic Review Protocol / Eficacia de las intervenciones educativas perioperatorias familiares centradas en la ansiedad, el dolor y las conductas de las personas menores y adolescentes y de sus progenitores: protocolo de revisión sistemática

Introduction: Every year, millions of children and adolescents undergo surgery, 50%-75% of them experience fear and anxiety. Children are particularly susceptible to stress and anxiety surrounding surgery as a result of their cognitive development, previous experiences, and knowledge about healthcare; this leads to additional interventions to prevent and reduce these symptoms. Objective: To evaluate the effectiveness of family-centered educational interventions in the children's and adolescents' anxiety, pain, and behaviors and their parents' anxiety during the perioperative period. Methods: This review will follow the Joanna Briggs Institute guidelines for systematic reviews of effectiveness and will consider those studies (experimental and quasi-experimental) in which perioperative educational interventions have been applied to children and adolescents and their parents; these studies measured children and adolescents' pain, anxiety, and behaviors, as well as their parent's anxiety. An initial search of MEDLINE and CINAHL will be followed by a second search for published and unpublished studies from January 2007 on, available in English, Spanish and Portuguese. After all full texts are retrieved, the methodological quality assessment and data extraction will be independently and critically evaluated by two reviewers, and the data will then be presented in a tabular format. An explanatory synthesis will accompany the results. Whenever possible, a meta-analysis will be performed, and a Grading of Recommendations, Assessment, Development, and Evaluation Summary of Findings will be presented. Expected Results: This review will provide guidance on how family-centred educational interventions can be used as a resource to manage anxiety, pain, and behavior in children, adolescents and their relatives during the perioperative processes.

Could CA 19-9 be a useful biomarker in the diagnosis, prognosis, and prediction of adequate relief in lower urinary tract obstructions?

INTRODUCTION: posterior urethral valves represent an important cause of childhood chronic kidney disease. The identification of biomarkers that indicate early kidney damage and even adequate clearance could reduce how many patients head towards kidney failure. OBJECTIVE: this study evaluated how this easy-analysis biomarker (CA 19-9) could help identifying potential renal damage and adequate clearance in obstructive uropathies. METHODS: 46 female Wistar rats were divided into 5 groups, with different patterns of partial urinary tract obstruction: group control; group OIV: infravesical obstruction; group OIVd: infravesical obstruction with reversion, obstruction relief 7 postoperative days later; group OUu: unilateral ureteral obstruction; group OUb: bilateral ureteral obstruction. The CA 19-9s performance was compared to another biomarker: Ngal. Determination of basal CA 19-9 and Ngal in urine and blood and serum creatinine levels was performed in the rats prior to surgery (T0) and after 14 days (T1). Group OIVd underwent intermediate (Ti) collection before clearance. RESULTS: the urinary concentration of CA 19-9 increased in groups OIV, OIVd and OUb; elevation at T1 and Ti, reached statistical significance compared to the T0 value (p<0,05). Changes in urinary CA 19-9 were more expressive in infravesical obstruction groups (AUC 0.81). Obstruction relief in group OIVd promoted significant urinary CA 19-9 reduction (p<0,05) in the final evaluation. CONCLUSIONS: CA 19-9 urinary concentration increased in partial urinary tract obstruction. Its best performance was in the bladder neck obstruction group, in which the elevation was detected early (6 days after infravesical obstruction) and the CA19-9 urinary concentration declined after clearance.

RESUMO Introdução: a válvula de uretra posterior representa uma importante causa de doença renal crônica na infância. A identificação de biomarcadores que monitorem danos renais precoces e o sucesso da desobstrução do trato urinário podem reduzir o número de pacientes que evoluem para insuficiência renal. Objetivo: avaliar o desempenho do biomarcador antígeno carboidrato CA 19-9 nas obstruções parciais do trato urinário. Método: 46 ratas Wistar foram divididas em 5 grupos: grupo controle; grupo OIV: obstrução infravesical; grupo OIVd: obstrução infravesical com alívio da obstrução após 7 dias; grupo OUu: obstrução ureteral unilateral; grupo OUb: obstrução ureteral bilateral. O desempenho do CA 19-9 foi comparado a outro biomarcador, a Ngal. A dosagem de CA 19-9 e Ngal na urina e no sangue, e os níveis de creatinina sérica foram avaliados nas ratas antes da cirurgia (T0) e após 14 dias (T1). O grupo OIVd foi submetido a uma coleta intermediária (Ti). Resultados: a concentração urinária de CA19-9 aumentou nos grupos OIV, OIVd e OUb; a elevação em T1 e Ti alcançou significância estatística em relação ao valor de T0 (p<0,05). As alterações no CA 19-9 urinário foram mais expressivas nos grupos de obstrução infravesical (AUC 0,81). O alívio da obstrução no grupo OIVd promoveu redução do CA 19-9 urinário (p<0,05). Conclusões: a concentração urinária de CA19-9 aumentou na obstrução parcial do trato urinário. Seu melhor desempenho foi no grupo de obstrução infravesical, no qual a elevação foi detectada precocemente (6 dias de pós-operatório) com queda após a retirada do fator obstrutivo.

Sclerosing Stromal Tumor of the Ovary: A Successful Laparoscopic Approach.

Sclerosing stromal tumors (SSTs) are a rare type of benign tumors of the ovary, representing 6% of sex cord tumors subtype. We report a case of SSTs affecting a young female patient presenting with abdominal pain and a pelvic mass on imaging examination. The patient underwent laparoscopic right salpingo-oophorectomy, and the pathology report confirmed the diagnosis of SSTs. A review of the literature with the typical pathological and imaging features of SSTs as well their management is performed.

Serum albumin modified by carbamoylation impairs macrophage cholesterol efflux in diabetic kidney disease.

BACKGROUND AND AIMS: Abnormalities in lipid metabolism, accumulation of uremic toxins and advanced glycation end products may contribute to worsening atherosclerosis. This study characterized the glycation and carbamoylation profile of serum albumin isolated from individuals with diabetic kidney disease and its influence on cholesterol efflux. MATERIAL AND METHODS: 49 patients with type 2 diabetes (T2DM) and different eGFR evaluated glycation and carbamoylation profile by measurement of carboxymethyl lysine (CML) and carbamoylated proteins (CBL) in plasma by ELISA, homocitrulline (HCit) in plasma by colorimetry. In the isolated albumins, we quantified CBL (ELISA) and total AGE and pentosidine by fluorescence. Macrophages were treated with albumin isolated, and 14C-Cholesterol efflux mediated by HDL2 or HDL3 was measured. Kruskal-Wallis test, Jonckheere-Terpstra test and Brunner's posttest were used for comparisons among groups. RESULTS: Determination of CML, HCit, CBL in plasma, as total AGE and pentosidine in albumins, did not differ between groups; however, CBL in the isolated albumins was higher in the more advanced stages of CKD (p=0.0414). There was reduction in the 14C-cholesterol efflux after treatment for 18h with albumin isolated from patients with eGFR<60mL/min/1.73m2 compared with control group mediated by HDL2 (p=0.0288) and HDL3 (p<0.0001), as well as when compared with eGFR ≥60mL/min/1.73m2 per HDL2 (p=0.0001) and HDL3 (p<0.0001). Treatment for 48h showed that eGFR<15mL/min/1.73m2 had a lower percentage of 14C-cholesterol efflux mediated by HDL2 compared to control and other CKD groups (p=0.0274). CONCLUSIONS: Albumins isolated from individuals with T2DM and eGFR<60mL/min/1.73m2 suffer greater carbamoylation, and they impair the cholesterol efflux mediated by HDL2 and HDL3. In turn, this could promote lipids accumulation in macrophages and disorders in reverse cholesterol transport.

Increased leukotriene B4 plasma concentration in type 2 diabetes individuals with cardiovascular autonomic neuropathy.

BACKGROUND AND AIM: A low-grade inflammation is associated with cardiac autonomic neuropathy (CAN) and increased concentration of leukotriene B4 (LTB4) was found in individuals with type 1 diabetes and definitive CAN. This cross-sectional study evaluated plasma concentration of LTB4 and of other inflammatory mediators, namely, tumor necrosis factor (TNF), interleukin (IL)1B, and IL10 in individuals with type 2 diabetes (T2D) and different degrees of CAN, and correlated these inflammatory mediators with the degree of glycemic control and with a surrogate marker of insulin resistance. METHODS: TNF, IL1B, IL10 and LTB4 plasma concentrations were measured in 129 T2D subjects (62% women with [median] age of 63 years, disease duration of 8 years and HbA1c of 7.3%) with or without CAN. The Lipid accumulation product index was used as a surrogate marker of insulin resistance. RESULTS: LTB4 concentration was significantly higher in those presenting incipient CAN (69.7 ± 16.6 pg mL-1) and definitive CAN (71.5 ± 15.7 pg mL-1) versus those without CAN (57.0 ± 13.9 pg mL-1). The groups without CAN and with incipient CAN were pooled (group without definitive CAN) and compared to those with definitive CAN. LTB4 concentration was higher in the latter group, as well as TNF concentration, while IL10 concentration was lower in this group. After adjustment for confounding variables, only LTB4 concentration remained significantly different between the groups with and without definitive CAN. Plasma concentration of LTB4 did not correlate with the degree of glycemic control. After sorting the participants by sex, a borderline weak correlation was found between LTB4 and the Lipid accumulation product index in women. CONCLUSION: In the T2D setting, circulating LTB4 concentration seems to be associated with cardiovascular dysautonomia.

Diabetic retinopathy screening in urban primary care setting with a handheld smartphone-based retinal camera.

AIMS: To evaluate diabetic retinopathy (DR) screening with a portable handheld smartphone-based retinal camera and telemedicine in an urban primary healthcare setting and to evaluate the learning curve for image acquisition, performed by healthcare personnel without previous experience in retinal imaging. METHODS: This was a prospective study that enrolled patients with type 2 diabetes mellitus (T2DM) followed at a primary healthcare unit in São Paulo, Brazil. After a brief training in image acquisition, there was further continuous feedback given by a retina specialist during the remote image reading process. Each patient underwent two fundus and one anterior ocular segment images per eye, after mydriasis. Patients were classified according to the need of referral. RESULTS: A total of 627 adult individuals with T2DM underwent retinal evaluation. The population was composed by 63.2% female individuals, age median of 66 years, diabetes duration 10.7 ± 8.2 years and HbA1c 7.7 ± 1.9% (61 + 20.8 mmol/mol). The most prevalent associated comorbidities were arterial hypertension (80.3%) and dyslipidemia (50.2%). Referral decision was possible in 81.2% patients. Most patients had absent or non-referable DR; the main ocular media opacity detected was cataract. After the 7th day of image acquisition, the daily rate of patients whose images allowed clinical decision was maintained above 80%. A higher HbA1c was associated with referable DR. CONCLUSIONS: A low-cost DR screening strategy with a handheld device and telemedicine is feasible and has the potential to increase coverage of DR screening in underserved areas; the possibility of mobile units is relevant for DR screening in the context of COVID-19 pandemic. Daily rate of patients whose examinations allowed clinical decision. X-axis: day of examination; Y-axis: rate (%) of patients whose examinations allowed a clinical decision.

Baby led weaning: an integrative review of scientific evidence from 2011 to 2019 / Baby-led weaning: uma revisão integrativa das evidências científicas de 2011 a 2019

INTRODUCTION: Baby-led weaning (BLW) is an alternative approach to introducing food to infants that has become popular. OBJECTIVE: To investigate the scientific evidence regarding the BLW method and its modified version, Baby-Led Introduction to Solids (BLISS). METHODS: The research was carried out between June 2018 and June 2019, through the databases US National Library of Medicine National Institutes of Health (PubMed) using the following keywords: 'BLW', 'Baby-led weaning', 'BLISS', and 'Baby-Led Introduction to Solids'. All original articles from in English published between 2011 and 2019 have been included. RESULTS: Twenty-five studies were included in the analysis. Research on BLW/BLISS focused mainly on the themes: characteristics, behaviors and attitudes of mothers and children, knowledge of mothers and health professionals about feeding methods, weight and body mass index evaluation of children, evaluation of energetic and nutrient intake of children and evaluation of episodes of choking and gag reflex. CONCLUSION: Most research deals with BLW-related experiences and there is still little evidence on the method in terms of adequacy of energy and nutrient intake and growth in childhood. Positive points to child can be observed such as prolonged breastfeeding, greater independence when feeding and better response to satiety. The methods of food introduction do not differ in relation to the occurrence of episodes of choking.

INTRODUÇÃO: O Baby-led weaning (BLW) é uma abordagem alternativa para a introdução alimentar aos lactentes que tem se tornado popular. OBJETIVO: Investigar as evidências científicas a respeito do método BLW e sua versão modificada Baby-Led Introduction to Solids (BLISS). MÉTODOS: A pesquisa de artigos foi realizada entre junho de 2018 e junho de 2019, por meio da base de dados US National Library of Medicine National Institutes of Health (PubMed) utilizando as seguintes palavras-chaves: 'BLW', 'Baby-led weaning', 'BLISS', e 'Baby-Led Introduction to Solids'. Foram incluídos todos os artigos originais encontrados no idioma inglês, publicados entre 2011 e 2019. RESULTADO: Vinte e cinco estudos foram incluídos na análise. As pesquisas sobre BLW/BLISS focaram principalmente nos temas: características, comportamentos e atitudes de mães e crianças, conhecimento de mães e profissionais de saúde sobre os métodos de introdução alimentar, avaliação de peso e de índice de massa corporal, avaliação da ingestão energética e de nutrientes e avaliação de episódios de engasgo e reflexo de gag das crianças. CONCLUSÃO: A maioria das pesquisas aborda experiências relacionadas ao BLW/BLISS e ainda existem poucas evidências sobre o método em termos de adequação de ingestão de energia e nutrientes e de crescimento na infância. Pontos positivos para a criança podem ser observados como aleitamento materno prolongado, maior independência ao se alimentar e melhor resposta à saciedade. Os métodos de introdução alimentar não diferem entre si em relação à ocorrência de episódios de engasgos.

EMA Review of Daunorubicin and Cytarabine Encapsulated in Liposomes (Vyxeos, CPX-351) for the Treatment of Adults with Newly Diagnosed, Therapy-Related Acute Myeloid Leukemia or Acute Myeloid Leukemia with Myelodysplasia-Related Changes.

On June 28, 2018, the Committee for Medicinal Products for Human Use adopted a positive opinion, recommending the granting of a marketing authorization for the medicinal product Vyxeos, intended for the treatment of acute myeloid leukemia (AML). Vyxeos was designated as an orphan medicinal product on January 11, 2012. The applicant for this medicinal product was Jazz Pharmaceuticals Ireland Limited. Vyxeos is a liposomal formulation of a fixed combination of daunorubicin and cytarabine, antineoplastic agents that inhibit topoisomerase II activity and also cause DNA damage. The strength of Vyxeos is 5 units/mL, where 1 unit equals 1.0 mg cytarabine plus 0.44 mg daunorubicin. The marketing authorization holder Jazz Pharmaceuticals had found that this was an optimal ratio for the efficacy of the product. Study CLTR0310-301, a phase III, multicenter, randomized, trial of Vyxeos (daunorubicin-cytarabine) liposome injection versus standard 3+7 daunorubicin and cytarabine in patients aged 60-75 years with untreated high-risk (secondary) AML, showed a statistically significant difference between the two groups in overall survival (OS) with a median OS of 9.56 months in the daunorubicin-cytarabine arm compared with 5.95 months for standard chemotherapy (hazard ratio, 0.69; 95% confidence interval, 0.52-0.90; one-sided p = .003). The most common side effects were hypersensitivity including rash, febrile neutropenia, edema, diarrhea/colitis, mucositis, fatigue, musculoskeletal pain, abdominal pain, decreased appetite, cough, headache, chills, arrhythmia, pyrexia, sleep disorders, and hypotension. IMPLICATIONS FOR PRACTICE: Vyxeos has demonstrated a clinically significant improvement in overall survival compared with the standard of care 7+3 in the proposed population of patients with newly diagnosed acute myeloid leukemia (AML) with myelodysplasia-related changes and therapy-related AML. This is remarkable given the very poor prognosis of these patients and their unmet medical need. Secondary endpoints support the primary outcome, in particular an increased rate of hematopoietic stem cell transplantation, which is potentially the only curative treatment in AML.

Association between health literacy and glycemic control in elderly patients with type 2 diabetes and modifying effect of social support / Associação entre alfabetismo em saúde e controle glicêmico em idosos com diabetes tipo 2 e efeito modificador do suporte social

ABSTRACT Objective: To investigate the association between inadequate functional health literacy, considering the Short Assessment of Health Literacy for Portuguese-speaking Adults, and glycemic control in elderly patients with type 2 diabetes, and to examine this association in low social support settings, according to Medical Outcomes Study . Methods: Cross-sectional study conducted at the diabetes referral center of a university hospital. Participants were recruited among type 2 diabetes patients aged 60 years or older, between May 2013 and November 2014. The primary outcome was the most recent glycated hemoglobin value measured within the last 6 months. Results: A total of 398 elderly patients with type 2 diabetes were evaluated. Of these, 232 were not eligible to participate. The final sample comprised 166 participants. Hierarchical multiple linear regression was performed. The following variables were entered in three blocks: sociodemographic characteristics, clinical variables and health literacy scores. Regression analysis of the interaction between health literacy and social support as a determinant of glycemic control was also performed. Mean age of subjects was 68.0 years (standard deviation of 5.9). Mean glycated hemoglobin value was 8.5% (standard deviation of 1.4). Short assessment of health literacy for Portuguese speaking adults score was independently associated with glycated hemoglobin (B=-0.059; p=0.043). The interaction between social support and health literacy score (p=0.003) was a determinant of glycemic control. Conclusion: Health literacy is associated with glycemic control. Social support may modify the relation between health literacy and glycemic control.

RESUMO Objetivo: Verificar a associação entre alfabetismo em saúde inadequado, segundo o Short Assessment of Health Literacy for Portuguese-speaking Adults , e controle glicêmico, em pacientes idosos com diabetes tipo 2, bem como avaliar tal associação no contexto de baixo suporte social, segundo o Medical Outcomes Study . Métodos: Estudo transversal conduzido no centro de referência de diabetes de um hospital universitário. Os participantes foram recrutados entre pacientes com diabetes tipo 2 com idade de 60 anos ou mais, entre maio de 2013 e novembro de 2014. O desfecho primário foi o valor mais recente de hemoglobina glicada obtido nos últimos 6 meses. Resultados: Foram avaliados 398 pacientes idosos com diabetes tipo 2. Destes, 232 não foram considerados elegíveis para participar da pesquisa. A amostra final incluiu 166 participantes. Foi realizada análise de regressão linear múltipla hierárquica com as seguintes variáveis inseridas em três blocos: características sociodemográficas, variáveis clínicas e escore de alfabetismo em saúde. Realizou-se também uma análise de regressão adicional da interação entre alfabetismo em saúde e apoio social como determinante do controle glicêmico. A média de idade dos indivíduos foi 68,0 anos (desvio-padrão de 5,9). O valor médio de hemoglobina glicada foi de 8,5% (desvio-padrão de 1,4). O Short Assessment of Health Literacy for Portuguese-speaking Adults mostrou-se independentemente associado à hemoglobina glicada (B=-0,059; p=0,043). A interação entre suporte social e escore de alfabetismo em saúde (p=0,003) foi determinante para o controle glicêmico. Conclusão: O alfabetismo em saúde está associado ao controle glicêmico. O suporte social pode modificar a relação entre o escore de alfabetismo em saúde e o controle glicêmico.

Aplicação de ferramentas de segurança alimentar como proposta de incentivo ao aprimoramento da produção de produtos lácteos caprinos / Application of food safety tools as a proposal of incentive for the enhancement of dairy goat production

O leite é um alimento nutritivo e perecível, tornando imprescindível a utilização de Boas Práticas de Fabricação (BPF) para sua produção segura. O objetivo do trabalho foi propor melhorias das BPF à um pequeno laticínio da Mesorregião Centro Fluminense que processa leite cabra. A partir de visitas técnicas, foram coletadas amostras de alimentos para realização de análises físico-químicas e microbiológicas bem como foi feito um diagnóstico das condições de produção por meio de uma lista de verificação. Diante das inadequações encontradas que incluíram desvios na estrutura predial, organização do laticínio, higiene e controle de qualidade da matéria-prima, produto final e seu transporte até os pontos de venda, foi elaborado um plano de ação para melhoria das BPF baseado no grau de importância e custo. Foi elaborado ainda alguns Procedimentos Padrão de Higiene Operacional e revisão do Manual de BPF do estabelecimento. Esta ação contribuiu para conscientizar o laticínio sobre a importância de avaliação constante e melhoria das BPF dos produtos lácteos caprinos.

Allelic variations in genes belonging to glutathione system increase proliferative retinopathy risk in type 1 diabetes individuals.

AIMS: Given the participation of oxidative stress in the pathogenesis of diabetic complications, we evaluated, in type 1 diabetes (T1D) individuals, the association between diabetic retinopathy (DR) and functional single nucleotide polymorphisms (SNPs) in regulatory regions of two genes belonging to the antioxidant glutathione (GSH) system: rs17883901 in GCLC and rs713041 in GPX4. METHODS: A cross-sectional case-control study included 288 individuals (61% women, 34[±11] years old, diabetes duration of 22[±9] years, mean [±SD]) sorted according to DR stages: absence of DR (ADR), non-proliferative DR (NPDR) and proliferative DR (PDR). SNPs were genotyped by real-time PCR using fluorescent labelled probes. Logistic regression models with adjustment for confounding covariates were employed. RESULTS: The presence of at least one T-allele of rs17883901 in GCLC was an independent risk factor for PDR (OR 4.13, 95% CI 1.38-13.66, p = 0.014) in a polytomous regression model (PDR versus ADR). The presence of at least one T-allele of rs713041 in GPX4 conferred protection against PDR (OR 0.30, 95% CI 0.11-0.80, p = 0.017) in female T1D individuals. CONCLUSION: The functional SNPs rs17883901 and rs713041 modulate the risk for PDR in the studied population of T1D individuals, widening the spectrum of candidate genes for this complication.

Anti-inflammatory and antinociceptive activities of the leaf methanol extract of Miconia minutiflora (Bonpl.) DC. and characterization of compounds by UPLC-DAD-QTOF-MS/MS.

Some species of the genus Miconia are used in Brazilian folk medicine as analgesic and anti-inflammatory; however, several species of this genus are still poorly studied. Therefore, the aims of this study were to investigate the phytochemistry characterization by UPLC-DAD-QTOF-MS/MS, acute toxicity, anti-inflammatory and antinociceptive properties of Miconia minutiflora (Bonpl.) DC. The methanol extract of M. minutiflora (Mm-MeOH) was subjected to ultra-high-performance liquid chromatography (UPLC-DAD-QTOF-MS/MS) for the identification of the main phytocompounds. The anti-inflammatory properties of the extracts were studied using several inflammation models induced by carrageenan and acetic acid-induced vascular permeability. Antinociceptive effects of Mm-MeOH were assessed in nociception induced by intraperitoneal acetic acid or subplantar formalin injection. The role of α-adrenergic, cholinergic, and opioid receptors in modulating the extract's antinociceptive activity was determined. Analyses by UPLC-DAD-QTOF-MS/MS revealed the presence of ellagic acid, gallotannin, and terpenes in the methanol extract. Mm-MeOH (100 mg/kg) reduced carrageenan-induced paw edema and vascular permeability and inhibited leukocyte migration toward the air pouch and pleural cavity. Furthermore, Mm-MeOH decreased tumor necrosis factor-α (TNF-α) and interleukin-1ß (IL-1ß) levels. Administration of Mm-MeOH reduced the number of writhes by 58.9% and increased the pain threshold in the formalin test. The anti-inflammatory action mechanism of Mm-MeOH is associated with inhibition of proinflammatory cytokines TNF-α and IL-1ß, whereas the antinociceptive actions involve peripheral and central mechanisms with participation of α2-adrenergic receptors. These effects may be attributed to the presence of polyphenolics in the extract.

Impact of Serum TSH and Anti-Thyroglobulin Antibody Levels on Lymph Node Fine-Needle Aspiration Thyroglobulin Measurements in Differentiated Thyroid Cancer Patients.

BACKGROUND: Thyroglobulin measurements in the washout of fine needle aspiration (FNA-Tg) are an excellent tool to detect lymph node (LN) metastases of differentiated thyroid carcinoma (DTC). Nevertheless, how to define the best cutoffs and the influence of potential confounders are still being discussed. OBJECTIVE: To evaluate the accuracy of FNA-Tg measurement to detect DTC metastases and the influence of thyroid status and anti-thyroglobulin antibodies (TgAb). METHODS: One hundred thirty-eight patients with DTC and suspicious cervical LN were included. Patients underwent ultrasound (US)-guided FNA for cytological examination and FNA-Tg measurements. Final diagnoses were confirmed by histological examination or clinical and US follow-up for at least 1 year. RESULTS: Data from 119 subjects with suspicious LN were evaluated. The median value of FNA-Tg in patients with metastatic LN (n = 65) was 3,263.0 ng/mL (838.55-12,507.5), while patients without LN metastasis (n = 54) showed levels of 0.2 ng/mL (0.2-0.2). According to the ROC curve analysis, the best cutoff value to predict metastasis was 4.41 ng/mL for FNA-Tg, with a sensitivity of 98% and specificity of 96%. There were no differences in the median of FNA-Tg measurements between those on (TSH 0.16 mUI/mL) and those off levothyroxine (TSH 99.41 mUI/mL) therapy (47.94 vs. 581.15 ng/mL, respectively; p = 0.79). Interestingly, the values of FNA-Tg in patients with LN metastasis (n = 65) did not differ between patients with positive and those with negative TgAb (88.8 vs. 3,263.0 ng/mL, respectively; p = 0.57). CONCLUSION: US-guided FNA-Tg proved to be a useful examination in the follow-up of patients with DTC, independently of TSH status and the presence of TgAb.

A relação entre as condições de trabalho e saúde dos estudantes trabalhadores / Relationship between labor conditions and health of working students

O objetivo deste estudo foi correlacionar condições de saúde às de trabalho de estudantes universitários trabalhadores a partir de uma revisão de literatura com a finalidade de sugerir ações promotoras de saúde. A pesquisa realizou-se por meio de revisão de literatura e pesquisa de campo, em que discute e analisa a relação entre as condições de trabalho e a saúde dos estudantes trabalhadores. O tempo de estudo escasso, a carga horária de trabalho associada e as horas insuficientes de descanso interferem diretamente no rendimento acadêmico familiar e laboral do estudante, podendo provocar distúrbios físicos, familiares e emocionais. É importante considerar que alguns hábitos podem prejudicar o rendimento dos mesmos como dormir tarde, má alimentação. Refletir sobre a realidade, as dificuldades enfrentadas e os fatores que possam afetar o desempenho do estudante trabalhador para promover sua saúde e qualidade de vida é importante. Foi possível identificar as situações que podem levar esse público à má qualidade de vida e ao adoecimento, embora muitas vezes, os próprios não percebam tal fato, considerando boas suas condições de saúde. Os resultados desta pesquisa apontam para a necessidade de novos estudos sobre a qualidade de vida dos estudantes universitários e podem trazer grandes contribuições para a proposição de ações promotoras de saúde aos mesmos.

Current investigation co-relates health conditions to labor conditions os working university students by a review of the literature for health enhancement activities. Research comprised a review of the literature and field research to analyze the relationships between labor conditions and the health of working students. Short study period, work load and insufficient rest time directly interfere on the academic yield and work of the students, with serious physical, family and emotional disorders. Certain habits, such as sleeping late and bad feeding actually harm school performance. It is highly important to discuss the difficulties to be coped with and the factors that may influence student´s performance for health improvement and better life quality. The situations that lead this type of population to a bad life quality and illness may be identified, even though they themselves fail to perceive this fact and think they have good health. Results reveal the need for further studies on the life quality of working students, with significant contributions for better health enhancements.

Performance of two alternative methods for Listeria detection throughout Serro Minas cheese ripening

ABSTRACT The ability of pathogens to survive cheese ripening is a food-security concern. Therefore, this study aimed to evaluate the performance of two alternative methods of analysis of Listeria during the ripening of artisanal Minas cheese. These methods were tested and compared with the conventional method: Lateral Flow System™, in cheeses produced on laboratory scale using raw milk collected from different farms and inoculated with Listeria innocua; and VIDAS®-LMO, in cheese samples collected from different manufacturers in Serro, Minas Gerais, Brazil. These samples were also characterized in terms of lactic acid bacteria, coliforms and physical-chemical analysis. In the inoculated samples, L. innocua was detected by Lateral Flow System™ method with 33% false-negative and 68% accuracy results. L. innocua was only detected in the inoculated samples by the conventional method at 60-days of cheese ripening. L. monocytogenes was not detected by the conventional and the VIDAS®-LMO methods in cheese samples collected from different manufacturers, which impairs evaluating the performance of this alternative method. We concluded that the conventional method provided a better recovery of L. innocua throughout cheese ripening, being able to detect L. innocua at 60-day, aging period which is required by the current legislation.

Native vaginal tissue repair for genital prolapse surgical treatment: a minimum of 30 months of results.

OBJECTIVE: The aim of this study was to assess the impact of using native vaginal tissue repair as a surgical treatment for pelvic organ prolapse (POP) on quality of life using validated questionnaires. STUDY DESIGN: Fifty-one women underwent surgical POP repair. All of the women were evaluated by physical examination using the POP-Q, ICIQ-VS and P-QoL questionnaires prior to surgery as well as six and at least 30 months after surgery. RESULTS: Fifty-one patients returned for assessment at least 30 months after surgery (median 36 months, range 30-50 months). There was significant improvement in most points - Aa, Ba, C, Bp, Ap, and hg - and at the stage of prolapse. There were statistically significant improvements in bulge symptoms after surgery (p<0.001), and significant differences were also seen regarding questions related to urinary and bowel symptoms. Indeed, most quality of life questionnaire domains showed significant differences before and after surgery. CONCLUSION: Native vaginal tissue repair improved POP-related symptoms and quality of life after 30-50 months of assessment.
