Assessment and indicators of kinematic behavior and perceived fatigability

SUMMARY OBJECTIVE: The objective of this study was to investigate the relationship between upper limb kinetics and perceived fatigability in elderly individuals during an upper limb position sustained isometric task. METHODS: A total of 31 elderly participants, 16 men (72.94±4.49 years) and 15 women (72.27±6.05 years), performed a upper limb position sustained isometric task. Upper-limb acceleration was measured using an inertial measurement unit. Perceived fatigability was measured using the Borg CR10 scale. RESULTS: Higher mean acceleration in the x-axis throughout the activity was associated with higher final perceived fatigability scores. Moderate correlations were observed between perceived fatigability variation and mean acceleration cutoffs in all axes during the second half of the activity. In women, significant correlations were found between all perceived fatigability cutoffs and mean acceleration in the y- and x-axes. However, in men, the relationships between perceived fatigability variation and mean acceleration were more extensive and stronger. CONCLUSION: The acceleration pattern of the upper limb is linked to perceived fatigability scores and variation, with differences between sexes. Monitoring upper limb acceleration using a single inertial measurement unit can be a useful and straightforward method for identifying individuals who may be at risk of experiencing high perceived fatigability or task failure.

Preoperative staging of uterine cancer: can transvaginal ultrasonography play a role?

Introduction: Preoperative staging of uterine cancer has recently been implied as an important contribution to an accurate selection of low-risk cases, ultimately avoiding unnecessary lymph node debulking. The aim of this study was to evaluate the validity of transvaginal ultrasonography (TVS) in preoperative staging of uterine cancer in comparison to pelvic magnetic resonance imaging (MRI) and permanent section. Methods: We conducted a prospective longitudinal multicenter trial between 2017 and 2018. Inclusion criteria comprised cases of endometrial neoplasia histologically confirmed or strong imaging suspicion, candidates for elective surgery as primary treatment. Proportions of Agreement (PA), kappa statistic (K), sensitivity, specificity and accuracy were calculated with 95% confidence intervals (95%CI). Results: Eighty-two patients were eligible for the study, presenting a mean age of 68 years (standard deviation 11). In what concerns the TVS evaluation of myometrial invasion, the subjective and objective methods of Gordon and Karlsson presented a sensitivity of 79%, 79% and 67% [95%CI 63-91; 63-91; 50-81], a specificity of 65%, 58% and 79% [95%CI 49-79; 42-73; 64-89] and an overall accuracy of 72%, 68% and 73% [95%CI 61-81; 57-78; 63-82]. MRI presented respectively a sensitivity, specificity and overall accuracy of 92%, 70% and 82% [95%CI 77-98; 52-85; 71-90]. Regarding cervical involvement, the sensitivity was respectively 31%, 50% and 67% [95%CI 9-61; 21-79; 35-90] for the subjective method, objective TVS and MRI, and the specificity was 98%, 90% and 100% [95%CI 92-100; 77-97; 94;100]. Agreement between TVS and MRI was superior in the assessment of cervical invasion, with PA ranging from 0.82 to 0.93 and K from 0.45 to 0.58, in comparison to myometrial invasion with PA ranging from 0.68 to 0.73 and K from 0.31 to 0.50. Considering the assessment of cervical involvement, as MRI showed a specificity of 100% it is not possible to increase the specificity. However, it was possible to increase the sensitivity, considering the combination of TVS with objective approach and MRI. Conclusion: TVS may have a promising role as a tool for preoperative staging of endometrial carcinoma, presenting a performance that approximates to MRI, with a higher agreement in the assessment of cervical invasion.

Risk Scoring Systems for Preterm Birth and Their Performance: A Systematic Review.

Introduction: Nowadays, the risk stratification of preterm birth (PTB) and its prediction remain a challenge. Many risk factors associated with PTB have been identified, and risk scoring systems (RSSs) have been developed to face this challenge. The objectives of this systematic review were to identify RSSs for PTB, the variables they consist of, and their performance. Materials and methods: Two databases were searched, and two authors independently performed the screening and eligibility phases. Records studying an RSS, based on specified variables, with an evaluation of the predictive value for PTB, were considered eligible. Reference lists of eligible studies and review articles were also searched. Data from the included studies were extracted. Results: A total of 56 studies were included in this review. The most frequently incorporated variables in the RSS included in this review were maternal age, weight, history of smoking, history of previous PTB, and cervical length. The performance measures varied widely among the studies, with sensitivity ranging between 4.2% and 92.0% and area under the curve (AUC) between 0.59 and 0.95. Conclusions: Despite the recent technological and scientifical evolution with a better understanding of variables related to PTB and the definition of new ultrasonographic parameters and biomarkers associated with PTB, the RSS's ability to predict PTB remains poor in most situations, thus compromising the integration of a single RSS in clinical practice. The development of new RSSs, the identification of new variables associated with PTB, and the elaboration of a large reference dataset might be a step forward to tackle the problem of PTB.

Programa de Controle do Tabaco: fatores associados ao risco de abandono do tratamento / obacco control program: factors associated with treatment dropout

No Brasil, a prevalência de tabagismo ainda é elevada em pessoas portadoras de Condições Crônicas não Transmissíveis (CCNT). A compreensão dos modelos de atenção ao tabagista é essencial para se reduzir o abandono do tratamento. Objetivos: identificar as características sociodemográficas e de saúde dos indivíduos que buscaram o Programa Nacional de Controle do Tabaco (PNCT) em duas Unidades Básicas de Saúde (UBS) do município de Campinas, estimar o percentual de abandono do tratamento e elencar os fatores associados a esse desfecho. Metodologia: coorte histórico cujos dados foram obtidos, entre 2016 e 2019, em grupos de tratamento do PNCT. Para a realização da análise exploratória, a pesquisa incluiu 276 participantes, dos quais foram registradas suas variáveis sociodemográficas, condições de saúde, formas de uso do tabaco e participação no programa. Foram estimados o índice de abandono do tratamento e as possíveis relações com as variáveis significativas através de regressão múltipla. Resultados: a média de idade foi de 50,7 anos, com 60% do sexo feminino, 57,7% brancos, 52,2% com companheiro, 84,7% com filhos, 52,5% com ensino fundamental, 64% com renda entre um e dois salários, 40,1% trabalhando em setor de serviços e 58% católicos. O percentual de abandono do tratamento foi de 31%. A hipertensão se relacionou com o abandono do tratamento (p=0,030), reduzindo-o. Conclusão: o perfil dos indivíduos foi semelhante ao encontrado em outras pesquisas; indivíduos não hipertensos apresentaram maioríndice de abandono. São necessários outros estudos que avaliem fatores associados ao abandono do tratamento

In Brazil, there is still a high prevalence of smoking among people with chronic diseases. The understanding of smoking treatments is essential to a reduction in treatment dropout. Objectives: to identify epidemiological and health aspects of smokers, estimate the dropout rates, and list the factorsassociated with treatment dropouts. Data from PNCT (National Program of Tobacco Control) treatment groups was obtained from a historical cohort between 2016 and 2019. The research included 276 participants with different sociodemographic realities, healthconditions, forms of tobacco use, and participation in the program to conduct an exploratory analysis. The treatment dropout rate and possible relations with significant variables were estimated through multiple regression. Results: The mean age was 50.7 years; 60% female; 57.7% white; 52.2% with a partner; 84.7% with children; 52.5% studied until elementary school; 64% received between one and two salaries; 40.1% worked in the service sector; 58% were Catholic. The percentage of treatment dropouts was 31%. Hypertension was related to treatment dropout (p = 0.030), reducing it. Conclusion: The profiles of individuals were similar to those in other surveys. Non-hypertensive individuals had a higher dropout rate. Further studies are needed to assess the factors associated with treatment dropout.

A Comparison of Intraocular Lens Power Calculation Formulas in High Myopia.

PURPOSE: To comparatively evaluate the accuracy of newer intraocular lens (IOL) calculation formulas and common third-generation formulas after Wang-Koch adjustment in the prediction of postoperative refraction in highly myopic eyes. METHODS: This was a retrospective study including eyes with high myopia that had uncomplicated cataract surgery with implantation of an AcrySof MA60MA IOL (power range: -5.00 to +5.00 diopters [D]) (Alcon Laboratories, Inc). All patients underwent optical biometry (Carl Zeiss IOLMaster 500 and IOLMaster 700, and Allegro Biograph) and the postoperative spherical equivalent for the implanted IOL was estimated using SRK/T, Holladay 1 (both Wang-Koch adjusted), Haigis, Barrett Universal II, Kane, Ladas, and Hill-RBF v2.0 formulas. Outcomes included the median absolute prediction error (MedAE) and the proportion of eyes within ±0.25, ±0.50, and ±1.00 D of the preoperative prediction. RESULTS: Eighty-two eyes with a mean axial length of 30.89 ± 1.85 mm were included. The MedAE in ascending order was Hill-RBF v2.0 0.31 D, Kane 0.33 D, Barrett 0.36 D, Holladay Iwk 0.37 D, SRK/Twk 0.37 D, Holladay Iwk 0.43 D, HaigisULIB 0.54 D, and Ladas 0.61 D. The formula with the lowest MedAE (Hill-RBF v2.0) yielded a prediction error within ±0.25, ±0.50, and ±1.00 D in 43.1%, 70.6%, and 94.1% of cases, respectively. CONCLUSIONS: Recent formulas such as Barrett Universal II, Kane, and Hill-RBF v2.0 and Wang-Koch adjusted formulas perform well in this subset of patients with high myopia. The Hill-RBF v2.0 formula had the lowest MedAE and highest proportion of eyes within ±0.25, ±0.50, and ±1.00 D of the predicted target. [J Refract Surg. 2021;37(3):207-211.].

Hysteroscopic Findings Related with the Assessment and Treatment of Uterine Florid Cystic Endosalpingiosis: A Case Report and Review of All the Published Cases.

INTRODUCTION: Endosalpingiosis is a rare benign condition characterized by the presence of tubal epithelium outside the Fallopian tube. The clinical presentation of endosalpingiosis is nonspecific, and the diagnosis is typically incidental in women undergoing surgery for pelvic pain, infertility, urinary symptoms, or a pelvic mass. It can only be confirmed with histopathological examination. CASE REPORT: We report the first case of uterine florid cystic endosalpingiosis, with unusual hysteroscopic findings. We reviewed all the published cases of uterine florid cystic endosalpingiosis and their clinical presentation including hysteroscopic characteristics. It is a rare benign condition, with only 32 cases described in the literature. This is the first hysteroscopic description of this condition to be made. DISCUSSION: The patient first underwent a hysteroscopy and a leiomyoma resection when she was 51 years old. At 55, she went through another hysteroscopy, and a polypoid lesion was excised. A third hysteroscopy, one year later, revealed a new polypoid lesion in a similar location. After the initial incisions, this polypoid lesion disappeared. By decreasing the intrauterine pressure, it became visible again, corresponding histologically to an endometrial polyp with tubal metaplasia. At last, she underwent a laparoscopic hysterectomy with a final histopathological diagnosis of uterine florid cystic endosalpingiosis. CONCLUSION: Florid cystic endosalpingiosis is a rare condition that may be associated with several bizarre hysteroscopic findings.

Introdução: A endossalpingiose é uma condição benigna rara caracterizada pela presença de epitélio tubário fora da trompa de Falópio. A apresentação clínica da endossalpingiose é inespecífica e o diagnóstico é geralmente incidental em mulheres submetidas a cirurgia por dor pélvica, infertilidade, sintomas urinários ou massa pélvica. O diagnostico só pode ser confirmado com exame histopatológico. Caso Clínico: Relatamos o primeiro caso de endosalpingiose cística florida uterina, no qual se encontrou achados histeroscópicos incomuns. Foram revistos todos os casos publicados de endosalpingiose cística florida uterina e suas apresentações clínicas, incluindo características histeroscópicas. Trata-se de uma condição benigna rara, com apenas 32 casos descritos na literatura. Apresentamos a primeira descrição histeroscópica desta patologia. Discussão: A doente foi submetida a uma primeira histeroscopia e resseção de leiomioma aos 51 anos de idade. Com 55, realizou uma nova histeroscopia e removeu uma lesão polipóide. Uma terceira histeroscopia, um ano depois, revelou uma nova lesão polipóide num local semelhante. Após as incisões iniciais, essa lesão polipóide desapareceu. Ao diminuir a pressão intrauterina, tornou-se visível novamente, correspondendo histologicamente a um pólipo endometrial com metaplasia tubária. A doente foi submetida a uma histerectomia laparoscópica com diagnóstico histopatológico final de endosalpingiose cística florida uterina. Foram revistos todos os casos publicados de endosalpingiose cística florida uterina e suas apresentações clínicas, incluindo características histeroscópicas. Conclusão: A endosalpingiose cística florida uterina é uma condição rara que pode estar associada a achados histeroscópicos bizarros.

Lung radiofrequency ablation: post-procedure imaging patterns and late follow-up.

PURPOSE: To describe expected imaging features on chest computed tomography (CT) after percutaneous radiofrequency ablation (RFA) of lung tumors, and their frequency over time after the procedure. METHODS: In this double-center retrospective study, we reviewed CT scans from patients who underwent RFA for primary or secondary lung tumors. Patients with partial ablation or tumor recurrence during the imaging follow-up were not included. The imaging features were assessed in pre-defined time points: immediate post-procedure, ≤4 weeks, 5-24 weeks, 25-52 weeks and ≥52 weeks. Late follow-up (3 and 5 years after procedure) was assessed clinically in 48 patients. RESULTS: The study population consisted of 69 patients and 144 pulmonary tumors. Six out of 69 (9%) patients had primary lung nodules (stage I) and 63/69 (91 %) had metastatic pulmonary nodules. In a patient-level analysis, immediately after lung RFA, the most common CT features were ground glass opacities (66/69, 96 %), consolidation (56/69, 81 %), and hyperdensity within the nodule (47/69, 68 %). Less than 4 weeks, ground glass opacities (including reversed halo sign) was demonstrated in 20/22 (91 %) patients, while consolidation and pleural thickening were detected in 17/22 patients (77 %). Cavitation, pneumatocele, pneumothorax and pleural effusions were less common features. From 5 weeks onwards, the most common imaging features were parenchymal bands. CONCLUSIONS: Our study demonstrated the expected CT features after lung RFA, a safe and effective minimally invasive treatment for selected patients with primary and secondary lung tumors. Diagnostic and interventional radiologists should be familiar with the expected imaging features immediately after RFA and their change over time in order to avoid misinterpretation and inadequate treatments.

Violência contra a mulher: o que acontece quando a Delegacia de Defesa da Mulher está fechada? / Violence against women: what happens when the Women's Protection Police Station is closed?

Resumo Este estudo analisa as diferenças entre os casos de violência contra a mulher, formalizados em boletins de ocorrência (BO) na Delegacia de Defesa da Mulher (DDM), durante a rotina dos formalizados nas Delegacias Civis durante os plantões policiais, em um município de médio porte do interior paulista. Trata-se de um estudo transversal, com base nos BOs realizados no período de um ano (2013/2014). As ocorrências foram diferenciadas conforme o período em que foram lavrados os BOs, na rotina ou nos plantões, sendo este último tomado como variável dependente. As comparações entre os grupos foram realizadas pelo teste χ2. Foram registrados 440 boletins, sendo 373 na rotina e 67 no plantão. As ocorrências realizadas nos plantões apresentaram maior ameaça à integridade da mulher com um maior número de flagrantes do agressor, solicitação de medidas protetivas e gravidade das agressões, como hematomas, hospitalização e encaminhamento ao IML; caracterizando maior gravidade das ocorrências no período em que a DDM está fechada. Deste modo, falta às mulheres um serviço especializado de acolhimento e ampla garantia de direitos nos períodos de maior risco e vulnerabilidade.

Abstract The study analyzes the differences among cases of violence against women registered in police reports (PR) at the Women's Protection Police Station (WPPS) during regular working hours, and those registered during after-hours, in a medium-sized city in the inland state of São Paulo, Brazil. This is a cross-sectional study based on data from PRs registered for one year (2013/2014). PRs were differentiated by period of registration, at regular working hours and after-hours (dependent variable). A chi-square test was used to compare groups. In total, 440 PRs were registered, 373 during regular working hours, and 67 during after-hours. Cases of violence registered during after-hours evidenced more significant threats to women's integrity, as shown by the higher number of cases of perpetrators' flagrante delicto, requests for protective measures and greater severity of assaults, such as bruises, need for hospitalization and referral to forensic medicine (IML), which characterize the greater severity of occurrences when WPPS are closed. Thus, women lack a specialized reception service and a full guarantee of rights in periods of highest risk and vulnerability.

Prevalence and factors associated with the occurrence of urinary incontinence during pregnancy / Prevalência e fatores associados à ocorrência de incontinência urinária na gestação

Abstract Objectives: to determine the prevalence of urinary incontinence (UI) during pregnancy, to identify and quantify the factors associated with gestational UI. Methods: a cross-sectional study carried out with women admitted for deliveries in all maternity wards in the city of Botucatu (São Paulo). Data were collected through a structured questionnaire, based on the literature, containing questions about the occurrence of UI, its types, risk factors and moments when urinary losses occurred. Associations between UI and the predictive variables were analyzed with logistic regression models. Results: 950 women were interviewed, out of which 472 complained of urinary losses during pregnancy, resulting in a prevalence of 49.68% (CI95%= 46.51 - 52.86). The majority (61.8%) were classified as mixed UI. Among the covariates investigated, smoking (OR= 4.56), illicit drugs use (OR= 25.14), stimulant foods (OR= 1.84), constipation (OR=1.99), hypertensive disorders during gestation (OR= 3.23), gestational diabetes mellitus (OR= 2.89), parity (OR= 1.52) and previous caesarean sections (OR= 2.56) increased the chance of urinary losses during pregnancy. Conclusions: there was a high prevalence of UI during pregnancy. This condition was strongly associated with lifestyle habits and gestational morbidities. Finally, it is worth high-lighting the fact that delivery via caesarean section increased the chance of UI in subsequent pregnancies.

Resumo Objetivos: estimar a prevalência de incontinência urinária (IU) na gestação, identificar e quantificar fatores associados à IU gestacional. Métodos: estudo transversal realizado com mulheres admitidas para o parto nas maternidades da cidade de Botucatu (São Paulo). Foi utilizado um questionário estruturado, baseado na literatura, contendo perguntas sobre a ocorrência de IU, seus tipos, fatores de riscos e momentos que ocorreram as perdas urinárias. Associações entre a ocorrência de IU e as variáveis preditoras foram analisadas por meio de modelos de regressão logística. Resultados: 950 mulheres foram entrevistadas, dessas 472 queixaram-se de perdas urinárias no período gestacional, resultando em uma prevalência de 49,68% (IC95%= 46,51 - 52,86), sendo a maioria (61,8%) classificada como IU mista. Entre as covariáveis investigadas, tabagismo (OR= 4,56), consumo drogas ilícitas (OR= 25,14), alimentos estimulantes (OR=1,84), constipação intestinal (OR= 1,99), distúrbios hipertensivos na gestação (OR=3,23), diabetes mellitus gestacional (OR= 2,89), paridade (OR=1,52) e parto cesárea (OR= 2,56) aumentaram a chance de perdas urinárias na gestação. Conclusões: houve uma alta prevalência de IU no período gestacional. Esta condição esteve fortemente associada à fatores como hábitos de vida e morbidades gestacionais. Por fim, merece destaque o achado que o parto via cesárea aumentou a chance de IU em gestação subsequente.

Factors Affecting Sick Leave Duration for Non-Work-Related Temporary Disabilities in Brazilian University Public Servants.

Sickness absenteeism in public institutions compromises the execution of services, and may also generate direct impacts on the population that receives coverage. To determine if sick leave duration for temporary disabilities is associated with non-work-related illnesses (NWRI), a historical cohort study was carried out of workers at a Brazilian University. The Charlson Comorbidity Index (CCI) was obtained from the most prevalent diagnoses in each expert examination and from the corresponding days of sick leave per episode, adjusting simple and multiple Cox regression models. As a result, 70% of the NWRI temporary disabilities were due to depressive disorders, convalescence, and dorsalgia with a sick leave duration between 4 and 320 days. The factors of protection for sick leave durations until the rehabilitation were non-insulin-dependent diabetes mellitus and hypertension. Long-term sick leaves were observed in the cases that required rehabilitation of those workers diagnosed with recurrent depressive disorders, conjunctivitis, acute sinusitis, skin disorders, calculus of kidney and ureter, abdominal and pelvic pain, and same-level fall accidents. It is also worth noting that even in a disease that can justify long-term sick leaves, such as breast cancer, the duration may be shorter according to the worker's capacity and self-efficacy.

Clinical benefit and radiological response with BRAF inhibitor in a patient with recurrent ameloblastoma harboring V600E mutation.

BACKGROUND: Ameloblastoma is a slow-growing neoplasm of the jaw, for which the standard treatment is surgical removal of the lesion with high recurrence rates and elevated morbidity. Systemic therapy is not established in the literature. CASE PRESENTATION: We present a case of a 29-year-old woman diagnosed with an ameloblastoma of the left mandible who had been subjected to several surgical procedures over twenty years due to multiple local recurrences. Molecular testing revealed a BRAF V600E mutation, and vemurafenib was started. She experienced complete resolution of symptoms related to the disease, and image scans evidenced continuous shrinkage of the neoplastic lesion after eleven months of therapy. CONCLUSION: This is the first report showing clinical benefit and radiological response with vemrafenib for recurrent ameloblastoma. Targeted therapy addressing BRAF V600E mutation has the potential to change clinical practice of this rare disease.

Real-World Results of Aflibercept versus Ranibizumab for the Treatment of Exudative AMD Using a Fixed Regimen.

Intravitreal injections of antivascular endothelial growth factors have been considered a milestone in the treatment of neovascular age-related macular degeneration (nAMD). However, the increasing incidence of AMD and the burden of visits and injections overcharge both the patient and the healthcare systems. Real-world solutions depend on treatment protocols aimed at optimizing the number of clinical visits while guaranteeing good functional outcomes. We performed a retrospective analysis of 72 eyes from 63 naïve patients diagnosed with nAMD that underwent a fixed intravitreal protocol consisting of bimonthly injections after a three-month loading dose, with either Aflibercept or Ranibizumab (no predefined criteria for treatment selection). Best corrected visual acuity (BCVA) and optical coherence tomography were analyzed at baseline and during follow-up clinical visits (months 3, 6, 12, and 18). From the included participants, 42 followed a fixed regimen with Aflibercept and 30 with Ranibizumab. At the 12-month visit, there was not a statistically significant difference in the mean change of BCVA between the two groups (p=0.121); however, the mean difference in the central retinal thickness was significantly superior in the Aflibercept group (-142.2 versus -51.5, p=0.011). The described fixed regimen seems to be efficient in the treatment of nAMD in a clinical practice setting.

Effect of clinical information and previous exam execution on observer agreement and reliability in the analysis of hysteroscopic video-recordings.

INTRODUCTION: Inter-observer agreement and reliability in hysteroscopic image assessment remain uncertain and the type of factors that may influence it has only been studied in relation to the experience of hysteroscopists. We aim to assess the effect of clinical information and previous exam execution on observer agreement and reliability in the analysis of hysteroscopic video-recordings. MATERIALS AND METHODS: Ninety hysteroscopies were video-recorded and randomized into a group without (Group 1) and with clinical information (Group 2). The videos were independently analyzed by three hysteroscopists, regarding lesion location, dimension, and type, as well as decision to perform a biopsy. One of the hysteroscopists had executed all the exams before. Proportions of agreement (PA) and kappa statistics (κ) with 95% confidence intervals (95% CI) were used. RESULTS: In Group 2, there was a higher proportion of a normal diagnosis (p < 0.001) and a lower proportion of biopsies recommended (p = 0.027). Observer agreement and reliability were better in Group 2, with the PA and κ ranging, respectively, from 0.73 (95% CI 0.62, 0.83) and 0.44 (95% CI 0.26, 0.63), for image quality, to 0.94 (95% CI 0.88, 0.99) and 0.85 (95% CI 0.65, 0.95), for the decision to perform a biopsy. Execution of the exams before the analysis of the video-recordings did not significantly affect the results. CONCLUSION: With clinical information, agreement and reliability in the overall analysis of hysteroscopic video-recordings may reach almost perfect results and this was not significantly affected by the execution of the exams before the analysis. However, there is still uncertainty in the analysis of specific endometrial cavity abnormalities.

Impressive response to immunotherapy in a metastatic gastric cancer patient: could somatic copy number alterations help patient selection?

BACKGROUND: Metastatic gastric cancer (GC) is an incurable and aggressive disease with a poor prognosis. Immunotherapy is an attractive approach for treating patients with cancer, and studies using immunotherapy have shown promising results in melanoma, kidney and non-small cell lung cancers, among others. CASE PRESENTATION: We present a case of a 50-year-old woman with metastatic GC whose cancer had progressed after first-line chemotherapy and who received pembrolizumab as an experimental treatment. Molecular analyses showed that her tumor was negative for PD-L1 expression, contained microsatellite stability and several focal somatic copy number alterations. The patient experienced an almost complete response after eleven cycles of treatment. Her symptoms related to the disease disappeared, and the medication was well tolerated. CONCLUSIONS: Despite reports of promising responses in some patients, immunotherapy is not suitable for all patients; therefore, we explored the molecular characteristics that could explain the exceptional response and clinical benefits observed in our patient.

Effectiveness of an illustrated home exercise guide on promoting urinary continence during pregnancy: a pragmatic randomized clinical trial / Efetividade de um manual de exercícios domiciliares na promoção da continência urinária durante a gestação: um ensaio clínico aleatorizado pragmático

PURPOSE: To evaluate the effectiveness of an illustrated home exercise guide targeting the pelvic floor muscles in promoting urinary continence during pregnancy.METHODS: A randomized clinical trial was performed with 87 participants, evaluated six times during pregnancy and divided into three groups: Gsup, supervised; Gobs, not supervised, and Gref, women who did not perform the home exercises program. A miction diary and perineometry were used to evaluate urinary incontinence (primary outcome) and pelvic floor muscle strength (secondary outcome), respectively. The Kruskal-Wallis test with post hoc Dunn's and chi-square and Z tests with Bonferroni correction were used for continuous variables and proportions, respectively, with the level of significance set at 5%.RESULTS: At the end of the study, 6.9% of pregnant women in the Gsup and Gobs had urinary incontinence, while 96.6% of Gref women were incontinent. Regarding pelvic floor muscle function, Gsup and Gobs had mean contractions of 10 and 8.9 cmH2O, respectively, while Gref had a value of 4.7 cmH2O. Both results were significant.CONCLUSION: An illustrated home exercise guide targeting the pelvic floor muscles is effective in promoting urinary continence during pregnancy, even without permanent supervision.

OBJETIVO: Avaliar a efetividade de um manual de orientação de exercícios domiciliares (MOED) para o assoalho pélvico (AP) na promoção da continência urinária em gestantes primigestas.MÉTODOS: Ensaio clínico com 87 participantes, avaliadas 6 vezes durante a gestação e divididas aleatoriamente em 3 grupos: Grupo supervisionado (Gsup), que praticou exercícios com supervisão; Grupo observado (Gobs), que praticou exercícios sem supervisão, e Grupo referência (Gref), que não praticou exercícios. Incontinência urinária (IU) (desfecho primário) e força muscular perineal (FMP) (desfecho secundário) foram avaliadas por intermédio de diário de perdas urinárias e perineometria, respectivamente. Foram utilizados o teste de Kruskal-Wallis, seguido do teste post hoc de Dunn, para variáveis contínuas, e o teste do χ2 e testes Z, com correções de Bonferroni, para proporções, com nível de significância de 5%.RESULTADOS: O Gsup e o Gobs apresentaram 6,9% de gestantes incontinentes, enquanto o Gref apresentou 96,6% de incontinentes. Quanto à FMP, o Gsup e o Gobs apresentaram valores médios de contração de 10 e 8,9 cmH2O, respectivamente, enquanto o Gref apresentou valor de 4,7 cmH2O. Ambos os resultados significantes.CONCLUSÃO: A utilização de um MOED é eficaz na promoção da continência urinária e no aumento da FMP em gestantes primigestas, independentemente de supervisão permanente.

Preeclampsia: a bioinformatics approach through protein-protein interaction networks analysis.

BACKGROUND: In this study we explored preeclampsia through a bioinformatics approach. We create a comprehensive genes/proteins dataset by the analysis of both public proteomic data and text mining of public scientific literature. From this dataset the associated protein-protein interaction network has been obtained. Several indexes of centrality have been explored for hubs detection as well as the enrichment statistical analysis of metabolic pathway and disease. RESULTS: We confirmed the well known relationship between preeclampsia and cardiovascular diseases but also identified statistically significant relationships with respect to cancer and aging. Moreover, significant metabolic pathways such as apoptosis, cancer and cytokine-cytokine receptor interaction have also been identified by enrichment analysis. We obtained FLT1, VEGFA, FN1, F2 and PGF genes with the highest scores by hubs analysis; however, we also found other genes as PDIA3, LYN, SH2B2 and NDRG1 with high scores. CONCLUSIONS: The applied methodology not only led to the identification of well known genes related to preeclampsia but also to propose new candidates poorly explored or completely unknown in the pathogenesis of preeclampsia, which eventually need to be validated experimentally. Moreover, new possible connections were detected between preeclampsia and other diseases that could open new areas of research. More must be done in this area to resolve the identification of unknown interactions of proteins/genes and also for a better integration of metabolic pathways and diseases.

Análise de indicadores da saúde materno-infantil: paralelos entre Portugal e Brasil / Analysis of maternal and child health indicators: the parallel between Portugal and Brazil

OBJETIVO: Analisar comparativamente as condições de nascimento em Portugal e no Brasil, no período entre 1975 a 2007. MÉTODOS: Os indicadores de saúde materno-infantis, razão de morte materna, mortalidade neonatal, taxa de cesarianas e gastos públicos em saúde, foram retrospectivamente coletados nas bases eletrônicas de informação do Sistema Único de Saúde (DATASUS), Instituto Nacional de Estatística de Portugal (INE), entre outras. Seus valores foram analisados descritivamente quanto a sua tendência e os cenários sanitários nos quais transcorreram foram apresentados e discutidos, comparando-se, sempre que possível, as informações dos dois países. RESULTADOS: Os nascimentos em Portugal caracterizaram-se por baixa mortalidade materna (12,2x76,2/100.000) e mortalidade neonatal (2,2x14,6/1000), comparativamente ao Brasil, na média dos anos 2004 a 2007. O histórico da conquista de indicadores materno-infantis de excelência em Portugal envolveu uma fase que transcorreu paralela às expressivas melhorias socioeconômicas e ao aporte crescente de recursos públicos em saúde, seguida de outra a partir da década de 1990, simultânea ao melhor aparelhamento das unidades de assistência à saúde. No Brasil, os índices de mortalidade materna e neonatal estão em queda, mas valores satisfatórios ainda não foram conquistados. A diferença histórica no montante do gasto público em saúde foi uma discrepância importante entre os países. A despeito das disparidades nos resultados maternos e neonatais, as taxas de cesariana mostraram-se igualmente ascendentes (34,5 por cento em Portugalx45,5 por cento no Brasil), na média do período 2004 a 2007. CONCLUSÃO: Os indicadores da morte materna e neonatal em Portugal e no Brasil alinharam-se às diferenças sociais, econômicas e aos aportes de investimentos públicos em saúde. As crescentes taxas de cesariana não explicam as discrepâncias no resultado materno e neonatal entre os países.

PURPOSE: To analyze comparatively the conditions of birth in Portugal and Brazil from 1975 to 2007. METHODS: Indicators of maternal and child health: rates of maternal death and neonatal mortality, cesarean rate and public spending on health were retrospectively collected from electronic databases of health information from the Unified Health System (DATASUS) and the National Institute of Statistics of Portugal (INE), among others. Their values were descriptively analyzed in terms of trends and the temporal sanitary scenarios were presented and discussed, comparing, when possible, the information from the two countries. RESULTS: Births in Portugal were characterized by lower maternal mortality (12.2x76.2/100.000) and neonatal mortality (2.2x14.6/1000), compared to Brazil, considering the average of the years from 2004 to 2007. The history of the conquest of maternal and child indicators of excellence in Portugal involved a phase that paralleled the significant socio-economic improvements and the increasing contribution of public health, followed by another from the 1990s, involving better equipped health care units. In Brazil, rates of maternal and neonatal mortality are declining, but satisfactory values have not yet been achieved. The historical difference in the amount of social spending on health, both in current and historical values, was a crucial difference between countries. Despite the disparities in maternal and neonatal outcomes, cesarean section rates were equally ascendant (34.5 percent in Portugal and 45.5 percent in Brazil), considering the average for the period from 2004 to 2007. CONCLUSION: The indicators of maternal and neonatal death in Portugal and Brazil have aligned themselves to social, economic and contributions of public investments in health. The increasing rates of caesarean section do not explain the discrepancies in maternal and neonatal outcome between countries.

A atuação do fi sioterapeuta nas perícias judiciais de LER/DORT / Physical therapist role in RSI/WRMSD legal expertise

Recentemente, o profi ssional fi sioterapeuta vem sendo designadocomo perito judicial, em ações de LER/DORT. Entretanto,em diversas ocasiões o mesmo sofre tentativas de impugnação, asquais, na maioria das vezes, são preconceituosas e infundadas. Nestecontexto, o objetivo deste estudo foi discutir o tema medianteanálise da legislação vigente, das diretrizes curriculares do curso defi sioterapia e das competências e habilidades do fi sioterapeuta, a fi mde demonstrar que o fi sioterapeuta é um profi ssional habilitado etotalmente capaz de realizar perícias judiciais sobre LER/DORT.Diante da análise feita neste estudo concluiu-se que o fi sioterapeutaalém de habilitado legalmente é o profi ssional mais indicado, devidoao estudo da cinesiologia e biomecânica, para realizar perícias nasquais os questionamentos estejam relacionados à análise de nexocausal e grau de capacidade funcional em casos de LER/DORT...

Recently, physical therapists have been designated as an expert,in RSI/WRMSD lawsuits. However, on several occasions theseprofessionals are subjected to attempts of impugnment, which,most of the times, are biased and unfounded. In this context, theobjective of this study was to discuss this topic through an analysisof the legislation, the curricular guidelines of the physical therapycourse and the physical therapists’ skills and abilities, in order todemonstrate that physical therapists are a qualifi ed professionaland fully capable of performing legal expertise in RSI/WRMSDcases. Was concluded that the physical therapist is not just legallyauthorized but he is the most qualifi ed professional, due to thestudy of kinesiology and biomechanics, to perform expertise whichquestions are related to the analysis of causal nexus and the degreeof functional capacity in RSI/WRMSD lawsuits...

Validade das tabelas de peso fetal clássicas para a população Portuguesa / Validity of classical fetal weight charts in the Portuguese population

OBJETIVO: avaliar a validade de várias tabelas de peso fetal, habitualmente usadas em Portugal, para classificar a sua população. MÉTODOS: estudo observacional retrospectivo. Foram analisados os registos de nascimentos no período de dois anos (Maio de 2008 a Abril de 2010), decorrentes de gestações unifetais com datação precisa por ecografia entre as 8ª e 14ª semanas de gestação, na mesma instituição. Após validação dos registos, foram analisados os percentis de peso gerados para cada semana de gestação completa, suavizados por uma função polinomial de dois graus, comparando-os com as tabelas mais usadas na instituição e no país, através do uso de Z-scores, valores de percentis, sensibilidade para detecção do percentil 10 (P10) da amostra e comparação de médias de peso. RESULTADOS: um total de 5.378 recém-nascidos (RN) foi registado no período; 2.195 (42 por cento) RN corresponderam aos critérios de inclusão, com idade gestacional (IG) entre as 24ª e 42ª semanas, permitindo uma análise estatística entre as 34ª e as 41ª semanas. Foram detectadas diferenças no peso médio por IG entre tabelas e em relação à amostra, bem como diferenças entre os sexos. O P10 de outros trabalhos mostrou diferenças entre -288g na 37ªs (-11 por cento nos dados de Lubchenco et al.) e +133g na 34ªs (+7,6 por cento nos dados de Carrascosa et al.) em relação ao obtido na amostra. A sensibilidade para detecção de um RN abaixo do P10 na amostra variou, às 39ªs, entre 14,1e 100 por cento, dependendo da tabela usada. DISCUSSÃO: as limitações deste tipo de valores de referência devem ser tidas em consideração, tentando minimizá-las, nomeadamente pela criação de valores locais/regionais ou nacionais, com a contemplação de outras variáveis, sobretudo o sexo do RN, em gravidezes rigorosamente datadas e pela validação in loco dos valores utilizados.

PURPOSE: to assess the validity of several fetal weight charts, commonly used in Portugal, to classify its population. METHODS: observational retrospective study. Singleton birth data was analyzed, from a two- year period (May 2008 to April 2010), from pregnancies with an ultrasound in the same institution, between the 8th and 14th gestational week. Upon data validation, percentiles for each completed gestational week were created, smoothed by a quadratic function, analyzed and compared to the tables more commonly utilized, in the institution and country, by using Z-scores, percentile comparison, sample 10th percentile detection sensibility and birthweight means comparison. RESULTS: a total of 5,378 newborns (NB) were born in the period; 2,195 (42 percent) NB were included, born from the 24th to 42nd gestational week, allowing statistical analysis from the 34th to the 41st week. There were differences in the mean birthweight for each gestational age, between references and with the sample, as well as between sexes. The 10th percentile from some references has shown differences ranging from -288g at 37 weeks (-11 percent in Lubchenco et al. data), with and +133g at 34 weeks (+7,6 percent with Carrascosa et al. data) compared to the values found with the sample. Differences were also found concerning the sensitivity of the identification of a sample birthweight below the 10th percentile, which was between 14.1 and 100 percent, depending on the reference used. DISCUSSION: the limitation of these kinds of reference values must be remembered and minimized, with the adoption of regionally or nationally produced references, contemplating other variables, such as sex, with precisely known gestation duration and with validation of the utilized references in loco.
