RESUMO
STUDY OBJECTIVES: Our aim was to review the evidence concerning the non-invasive diagnosis of endometriosis in adolescents. METHODS: A systematic review was written following the SWiM reporting guidelines. The study research was made across three databases (MEDLINE/PubMed, Scopus, and Web of Science) to identify articles about the adolescent population and the diagnosis of endometriosis through non-invasive methods. The search included the keywords "endometriosis," "adolescents," "diagnosis," "ultrasound," and "MRI." Only English-language articles were considered, and those published prior to 2000 were excluded. The established outcomes focused on clinical symptoms, ultrasound (US), and magnetic resonance imaging (MRI) findings suggestive of endometriosis. RESULTS: We included 26 articles, mostly comprising case series and cross-sectional studies. The pooled analysis involved 2,299 female adolescents (age range 8-25 years old) with clinically suspected, imaged, and/or surgically confirmed endometriosis. The most frequently reported symptom was dysmenorrhea, followed by chronic pelvic pain. Among adolescents clinically suspected of endometriosis undergoing ultrasound (US), 32.8% exhibited at least one sign of endometriosis. Of the 167 patients with ultrasound-diagnosed endometriosis, 48.5% had deep infiltrating endometriosis (DIE), and 45.5% had an endometrioma detected. Three studies assessed MRI findings, revealing that 49.8% presented with signs of endometriosis. CONCLUSIONS: Dysmenorrhea and chronic pelvic pain stand out as key symptoms of adolescent endometriosis. Although their diagnostic accuracy varies, US and MRI have emerged as valuable tools for diagnosing the disease. While the US may have limitations, especially in detecting subtle lesions, MRI shows promise, even in cases with normal previous ultrasounds. Early recognition and proactive diagnosis are crucial for improving the management of endometriosis in adolescents.
RESUMO
PURPOSE: To evaluate the prognostic impact of hyperreflective foci (HRF) on spectral-domain optical coherence tomography (SD-OCT) in nonsyndromic retinitis pigmentosa (RP). METHODS: Retrospective, single-center cohort study including genetically-tested RP patients with a minimum follow-up of 24 months. Clinical data including demographics, genetic results and best-corrected visual acuity (BCVA) at baseline and follow-up were collected. Horizontal and vertical SD-OCT scans were analyzed by 2 independent graders. Outer nuclear layer (ONL) thickness and ellipsoid zone (EZ) width were manually measured in horizontal and vertical scans. HRF were classified according to location: outer retinal layers within the central 3mm (central-HRF), outer retinal layers beyond the central 3mm (perifoveal-HRF), and choroid (choroidal-HRF). Central macular thickness (CMT), central point thickness (CPT) and choroidal thickness (CT) at baseline and follow-up were also recorded. RESULTS: A total of 175 eyes from 94 RP patients (47.9% female, mean age 50.7±15.5 years) were included, with a mean follow-up of 29.24±7.17 months. Mean ETDRS (early treatment diabetic retinopathy study) BCVA decreased from 61.09±23.54 to 56.09±26.65 (p=0.082). At baseline, 72 eyes (41.1%) showed central-HRF, 110 eyes (62.9%) had perifoveal-HRF and 149 eyes (85.1%) exhibited choroidal-HRF. Central-HRF and perifoveal-HRF were associated with worse final BCVA, as well as greater BCVA deterioration (all p<0.0029). Only central-HRF were associated with a worse final CMT (p<0.001). Shorter EZ widths were associated with all types of HRF (p<0.05). Perifoveal and choroidal-HRF predicted smaller final EZ areas (p<0.01). CONCLUSION: HRF are highly prevalent in RP patients and appear to have a negative prognostic impact in visual function and EZ area.
RESUMO
Monitoring fetal heart rate (FHR) through cardiotocography is crucial for the early diagnosis of fetal distress situations, necessitating prompt obstetrical intervention. However, FHR signals are often marred by various contaminants, making preprocessing techniques essential for accurate analysis. This scoping review, following PRISMA-ScR guidelines, describes the preprocessing methods in original research articles on human FHR (or beat-to-beat intervals) signal preprocessing from PubMed and Web of Science, published from their inception up to May 2021. From the 322 unique articles identified, 54 were included, from which prevalent preprocessing approaches were identified, primarily focusing on the detection and correction of poor signal quality events. Detection usually entailed analyzing deviations from neighboring samples, whereas correction often relied on interpolation techniques. It was also noted that there is a lack of consensus regarding the definition of missing samples, outliers, and artifacts. Trends indicate a surge in research interest in the decade 2011-2021. This review underscores the need for standardizing FHR signal preprocessing techniques to enhance diagnostic accuracy. Future work should focus on applying and evaluating these methods across FHR databases aiming to assess their effectiveness and propose improvements.
RESUMO
BACKGROUND: Considering the challenges posed by nitrogen (N) pollution and its impact on food security and sustainability, it is crucial to develop management techniques that optimize N fertilization in croplands. Our research intended to explore the potential benefits of co-inoculation with Azospirillum brasilense and Bacillus subtilis combined with N application rates on corn plants. The study focused on evaluating corn photosynthesis-related parameters, oxidative stress assay, and physiological nutrient use parameters. Focus was placed on the eventual improved capacity of plants to recover N from applied fertilizers (AFR) and enhance N use efficiency (NUE) during photosynthesis. The two-year field trial involved four seed inoculation treatments (control, A. brasilense, B. subtilis, and A. brasilense + B. subtilis) and five N application rates (0 to 240 kg N ha-1, applied as side-dress). RESULTS: Our results suggested that the combined effects of microbial consortia and adequate N-application rates played a crucial role in N-recovery; enhanced NUE; increased N accumulation, leaf chlorophyll index (LCI), and shoot and root growth; consequently improving corn grain yield. The integration of inoculation and adequate N rates upregulated CO2 uptake and assimilation, transpiration, and water use efficiency, while downregulated oxidative stress. CONCLUSIONS: The results indicated that the optimum N application rate could be reduced from 240 to 175 kg N ha-1 while increasing corn yield by 5.2%. Furthermore, our findings suggest that replacing 240 by 175 kg N ha-1 of N fertilizer (-65 kg N ha-1) with microbial consortia would reduce CO2 emission by 682.5 kg CO2 -e ha-1. Excessive N application, mainly with the presence of beneficial bacteria, can disrupt N-balance in the plant, alter soil and bacteria levels, and ultimately affect plant growth and yield. Hence, highlighting the importance of adequate N management to maximize the benefits of inoculation in agriculture and to counteract N loss from agricultural systems intensification.

Background: COVID-19 pandemic imposed drastic and abrupt changes to working environment and organization and that might have caused additional negative effects on mental health. Thus, this study aimed to quantify and assess the severity of psychological distress experienced by Brazilian essential and nonessential workers during the first months of the COVID-19 pandemic. Methods: This descriptive study included 2,903 participants who answered an online questionnaire between April and May 2020. The research questionnaire was translated and culturally adapted to the Brazilian population from a questionnaire developed and validated for the Spanish population. Variables were analyzed using simple and cumulative percentage distributions and measures of central tendency and dispersion. The Wilson score interval was used to calculate confidence interval (CI) for the main outcome, psychological distress. Results: It was observed a high prevalence (72.6%) of psychological distress among the study's participants. They also presented a median risk perception score of 60 (out of a maximum of 90), and their greatest concern was transmitting the virus to family members, close contacts or patients. Furthermore, it was found a lower sense of coherence and work engagement among the participants than those observed in previous studies conducted in other countries. Conclusion: Almost three quarters of the study's participants were classified as presenting psychological distress. Thus, it is imperative to provide mental health remotely delivered interventions to workers during public health events that require prolonged social distancing measures.

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.

Strategies seeking to increase the use efficiency of nitrogen (N) fertilizers and that benefit plant growth through multiple mechanisms can reduce production costs and contribute to more sustainable agriculture free of polluting residues. Under controlled conditions, we investigated the compatibility between foliar inoculation with an endophytic diazotrophic bacterium (Herbaspirillum seropedicae HRC54) at control and low, medium and high N fertilization levels (0, 25, 50 and 100 mg of N kg-1 as urea, respectively) in Marandu palisadegrass. Common procedures in our research field (biometric and nutritional assessments) were combined with isotopic techniques (natural abundance - δ15N and 15N isotope dilution) and root scanning to determine the contribution of fixed N and recovery of N fertilizer by the grass. Overall, the combined use of 15N isotopic techniques revealed that inoculation not only improved the recovery of applied N-urea from the soil but also provided fixed nitrogen to Marandu palisade grass, resulting in an increase in the total accumulated N. When inoculated plants grew at control and low levels of N, a positive cascade effect encompassing root growth stimulation (nodes of smaller diameter roots), better soil and fertilizer resource exploitation and increased forage production was observed. In contrast, increasing N reduced the contributions of N fixed by H. seropedicae from 21.5% at the control level to 8.6% at the high N level. Given the minimal to no observed growth promotion, this condition was deemed inhibitory to the positive effects of H. seropedicae. We discuss how to make better use of H. seropedicae inoculation in Marandu palisadegrass, albeit on a small scale, thus contributing to a more rational and efficient use of N fertilizers. Finally, we pose questions for future investigations based on 15N isotopic techniques under field conditions, which have great applicability potential.

Objectives: To validate the items of the Emotional Impact Questionnaire coronavirus disease-2019 (COVID-19) related to risk perception, estimating its degree, among healthcare workers in the first wave of COVID-19 pandemic, identifying possible associated factors.Methods: cross-sectional study in 1872 healthcare workers of Brazil. The population was characterized by sociodemographic and occupational information, knowledge about COVID-19, quality of information received, risk perception and preventive measures about the disease, and sense of coherence. Results: Being divorced, having a chronic disease, spending more than 1 h per day getting informed about COVID-19, and always or almost always wearing a mask regardless of symptoms, as well as self-perception of health were associated with high-risk perception. An inverse association was found between risk perception, sense of coherence and not knowing if one has had occasional contact with confirmed COVID-19 cases. Conclusion: Risk perception is influenced by emotions, experiences, and knowledge. Sense of coherence and resilience have a role in reducing risk perception. Understanding risk perception is crucial for developing effective strategies to mitigate the impact of the COVID-19 pandemic and other similar scenarios.

RESUMO
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.
RESUMO
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.
RESUMO
Upper-limb position-sustained tasks (ULPSIT) are involved in several activities of daily living and are associated with high metabolic and ventilatory demand and fatigue. In older people, this can be critical to the performance of daily living activities, even in the absence of a disability. OBJECTIVES: To understand the ULPSIT effects on upper-limb (UL) kinetics and performance fatigability in the elderly. METHODS: Thirty-one (31) elderly participants (72.61 ± 5.23 years) performed an ULPSIT. The UL average acceleration (AA) and performance fatigability were measured using an inertial measurement unit (IMU) and time-to-task failure (TTF). RESULTS: The findings showed significant changes in AA in the X- and Z-axes (p < 0.05). AA differences in women started earlier in the baseline cutoff in the X-axis, and in men, started earlier between cutoffs in the Z-axis. TTF was positively related to AA in men until 60% TTF. CONCLUSIONS: ULPSIT produced changes in AA behavior, indicative of movement of the UL in the sagittal plane. AA behavior is sex related and suggests higher performance fatigability in women. Performance fatigability was positively related to AA only in men, where movement adjustments occurred in an early phase, though with increased activity time.
RESUMO
This study aimed to evaluate the impact of low back pain on the perceived health-related quality of life of children between 6 and 12 years of age. This is a cross-sectional study of three hundred seventy-seven students from three schools (two private and one public) located in the city of Botucatu, São Paulo. Data were collected using the Pediatric Quality of Life Inventory (PedsQL, version 4.0), a questionnaire comprising questions on personal background, sociodemographic and socioeconomic information, and a questionnaire about quality of life. Comparisons were made between groups with and without low back pain. The chi-squared test was used for analyzing categorical variables, and the non-parametric Mann-Whitney test was used for continuous variables. According to the findings obtained in this study, it was observed that low back pain in the last month was reported by 27.3% of the total participants. The perceived health-related quality of life was lower among individuals who had low back pain, and the scores of physical and emotional functioning domains were also lower in the presence of low back pain. The prevalence of low back pain among children and adolescents is relatively high. Furthermore, the repercussions of low back pain may lead to a lower overall perception of the health-related quality of life in this population and affect aspects of physical and emotional functioning.
RESUMO
OBJECTIVES: The objective of this study is to present the why, what and how about computerized analysis of cardiotocograms (cCTG) and the SisPorto system for cCTG. CONTENT: A narrative review about cCTG and the SisPorto system for cCTG is presented. The meta-analysis of randomized controlled trials (RCT) performed so far have evidenced that cCGT compared to traditional CTG analysis may save time spent in hospital for women, in the antepartum period, and is objective with at least equivalent results in maternal and perinatal outcomes, both in the ante and intrapartum periods. The SisPorto system for cCTG closely follows the FIGO guidelines for fetal monitoring. It may be used both in the ante and intrapartum periods, alone or connected to a central monitoring station, with simultaneous monitoring of fetal and maternal signals, not only in singletons but also in twins. It has been assessed in technical, physiopathological and clinical studies, namely in one large multicentric international RCT during labor and two meta-analysis. SUMMARY AND OUTLOOK: There is evidence that cCTG may be useful in clinical practice with advantages compared to traditional CTG analysis, although without clear impact on the decrease of preventable maternal and perinatal mortality and morbidity. More studies are warranted, namely on technical improvements and assessment in larger studies in a wider range of clinical settings.

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.

Purpose: This study aimed to evaluate the long-term effectiveness of intravitreal anti-vascular endothelial growth factor (VEGF) injections in the treatment of choroidal neovascularization (CNV) associated with angioid streaks. Methods: Multicenter retrospective cohort study, including eyes with CNV secondary to angioid streaks treated with anti-VEGF injections, were performed. Best-corrected visual acuity (BCVA) in ETDRS letters; qualitative and quantitative (foveal thickness) OCT parameters; anti-VEGF type; and number of injections were collected at baseline and at 3, 6, 12, 24, 36, 48, 60, and 72 months. Results: Thirty-nine eyes from 29 patients, 17 (58.6%) females, were included. The mean follow-up time was 69.4 ± 34.5 months. BCVA was 59.3 ± 23.3 letters at baseline and 63.7 ± 21.9 letters at 48 months. At 3 months, BCVA improved 6.9 ± 11.7 letters (P=0.003). Then, BCVA remained stable. The mean foveal thickness decreased from 343.3 ± 120.2 µm at baseline to 268.3 ± 65.4 at 48 months (P=0.021). The mean number of injections was 4.6 ± 2.1 at 12 months, decreasing to 1.7 ± 2.4 injections between 36 and 48 months (P=0.093). Conclusion: This real-world study suggests that the functional and morphologic response to anti-VEGF therapy for CNV related to angioid streaks is generally satisfactory and maintained in the long term.
RESUMO
As coronavirus disease 2019 (COVID-19) is asserting itself as a health crisis, it is necessary to assess the knowledge and perceptions of people about the disease. The aim of this study is to assess the knowledge of the general population about COVID-19 and how the media influence this knowledge. This is a cross-sectional study with 5066 participants who answered an online questionnaire between April and May 2020. Data analysis was performed using descriptive statistics and logistic regression models. Over 75% have obtained a high degree of knowledge regarding signs, symptoms, and transmission, 95% stated to check the veracity of the information received, and also showed that the total knowledge about COVID-19 was associated with the level of instruction, with the perception of the quality of information disseminated by the media, and with the risk perception. Despite the high level of knowledge of participants, the results pointed to the need to reinforce information for individuals with less education and the importance of avoiding denialism that reduces the risk perception about COVID-19.

ABSTRACT: Health care professional's knowledge is essential to contain epidemics. This research aimed to evaluate the knowledge of Brazilian health care professionals regarding COVID-19 to analyze whether there is a difference in knowledge between professionals in Primary Health Care and those in other levels of care or not; and to identify factors associated with knowledge. This is a cross-sectional study, including 716 participants who answered an online questionnaire between April and May 2020. Descriptive statistics, difference tests between groups, and logistic regression models were used to analyze the data. The average knowledge score was 12.42 points (out of a possible total of 15). There was no significant difference between professionals in Primary Health Care and those in other levels of care. Knowledge was associated with age, profession, perception regarding media's information quality, and hours exposed to information on COVID-19. Participants showed adequate knowledge, despite some specific gaps. Continuing education actions should prioritize younger nonmedical professionals.

AIM: To investigate the level of self-reported work ability and its association with manual patient handling in healthcare workers. DESIGN: Cross-sectional study adhering to the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) guidelines. METHODS: A total of 320 healthcare workers answered a self-administered questionnaire regarding manual patient handling, work ability, occupational factors, occurrence of low back pain and sociodemographic and lifestyle factors from November 2016 to March 2017. The association between manual patient handling and low back pain was analysed with Poisson regression models. RESULTS: The prevalence ratio of inadequate work ability was 43.42%. Manual patient handling (PR 1.375, 95% CI 1.038-1.821), bachelor education (PR 2.150, 95% CI 1.272-3.632), less than bachelor education (PR 2.166, 95% CI 1.218-3.855), seniority (PR 1.049, 95% CI 1.024-1.086), poor sleep quality (PR 1.425, 95% CI 1.13-1.796) and presence of low back pain (PR 2.003, 95% CI 1.314-3.052) were all positively associated with an inadequate work ability.
