A nationwide study on immunosenescence biomarkers profile in older adults: ELSI-Brazil.

Immunosenescence is a phenomenon caused by changes in the immune system, and part of these changes involves an increase in circulating immunological biomarkers, a process known as "Inflammaging." Inflammaging can be associated with many diseases related to older people. As the older population continues to grow, understanding changes in the immune system becomes essential. While prior studies assessing these alterations have been conducted in countries with Caucasian populations, this investigation marks a pioneering effort. The object of the study is to describe for the first time that the distribution of cytokines, chemokines, and growth factors serum levels, assessed by Luminex platform, has been examined in a Brazilian population-based study of older adult females and males by age. Blood samples from 2111 participants (≥50 years old) were analyzed at the baseline (2015/2016) of the ELSI-Brazil study. The exploratory variables considered in the study were age, sex, educational level, residence area, geographic region, alcohol and smoking consumption, physical activity, and self-reported medical diagnoses of hypertension, diabetes, asthma, arthritis, and cancer. The association between serum biomarker levels and age was assessed by a quantile regression model adjusted in the total population and stratified by sex. The significance level considered in the analysis was 0.05. The mean age of the participants was 62.9 years, with a slight majority of female (52.7 %). Differences were found between the sexes in the median circulating levels of the CCL11, CXCL10, and FGF biomarkers. Eight biomarkers showed significant associations with age, including the pro-inflammatory CXCL10, TNF-α, IL-6, IL-17, and IL-2; and type 2/regulatory CCL11 and IL-4, showing positive associations, and anti-inflammatory IL-1Ra showing a negative association. The results suggest similar associations between the sexes, revealing an inflammatory profile characterized by types 1 and 2. Remarkably, these findings reinforce the concept of the Inflammaging process in Brazilian population. These findings add novel insights to about the immunosenescence aspects in middle-income countries and help define biomarkers capable of monitoring inflammation in older adults.

Olmesartan-Induced Enteropathy: When the Treatment of One Disease Causes Another.

Olmesartan is an angiotensin II receptor antagonist used for the management of hypertension. This drug can lead to an enteropathy that clinically and histologically resembles coeliac disease. Symptoms may appear months or years after the introduction of the drug and usually resolve after discontinuation. The authors present a case of an 86-year-old woman with hypertension who was treated with olmesartan for 10 years. She presented to the emergency department with diarrhoea after three months of development and weight loss. The aetiological study that was conducted excluded infectious, inflammatory, endocrinological, and neoplastic causes. The pathological anatomy of the duodenal biopsy was suggestive of coeliac disease, but the serology was not compatible. The patient presented complete remission of the condition with the suspension of the drug and subsequent recrudescence when, by self-initiation, she resumed olmesartan. This case study aims to alert readers of a rare cause of enteropathy with a clinical manifestation that mimics coeliac disease. Olmesartan-induced enteropathy seems to be a diagnosis of exclusion and should be considered in patients chronically medicated with olmesartan.

From Suspected COVID-19 to Anti-synthetase Syndrome: A Diagnostic Challenge in the Pandemic Era.

Anti-synthetase syndrome (ASS), a rare immunomediated disease, is characterized by multiple signs and symptoms. Not all patients develop the entire clinical spectrum of the syndrome, as it often varies depending on the involved antibodies. In this case report, a 53-year-old non-smoking woman had complaints of fatigue and dyspnea on exertion for five weeks. The outpatient study revealed creatine kinase (CK) 351U/L, ANAs+, anti-SSa+, normal echocardiogram, and a chest X-ray suggesting imaging suspicion of SARS-CoV-2 pneumonia. Referred to the emergency department, she was hospitalized for bilateral interstitial pneumonia without respiratory failure. Three SARS-CoV-2 polymerase chain reaction tests were negative. She underwent a five-day course of dexamethasone 6mg due to suspected coronavirus disease 2019 (COVID-19) sequelae with favorable progress. About a month later, she experienced fatigue, exertional intolerance, morning cough, and Raynaud's phenomenon episodes. Anti-SARS-CoV-2 antibodies were negative, and a follow-up chest CT showed bilateral organizing pneumonia. Bronchofibroscopy and bronchoalveolar lavage with cytology suggestive of inflammatory appearance, predominantly CD8+ lymphocytes, were performed. Subsequently, positive results for anti-OJ antibodies were obtained. A diagnosis of ASS was established, and prednisolone was initiated at 60mg/day with a tapering regimen, resulting in clinical and radiological improvement. Additional therapy with azathioprine was proposed. This case is presented due to highly suggestive COVID-19 imaging changes, emphasizing the importance of a high suspicion of ASS, despite nearly exclusive pulmonary involvement, with only one isolated elevated CK value and no musculoskeletal complaints. It is also noteworthy for the association with anti-OJ antibodies, rarely identified, often presenting interstitial lung disease as an isolated manifestation.

Prediabetes remission after bariatric surgery: a 4-years follow-up study.

BACKGROUND: Bariatric surgery leads to weight loss and to cardiometabolic risk improvement. Although prediabetes remission after bariatric surgery is biologically plausible, data on this topic is scarce. We aimed to assess prediabetes remission rate and clinical predictors of remission in a 4 year follow up period. METHODS: Observational longitudinal study including patients with obesity and prediabetes who had undergone bariatric surgery in our centre. Prediabetes was defined as having a baseline glycated haemoglobin (A1c) between 5.7% and 6.4% and absence of anti-diabetic drug treatment. We used logistic regression models to evaluate the association between the predictors and prediabetes remission rate. RESULTS: A total of 669 patients were included, 84% being female. The population had a mean age of 45.4 ± 10.1 years-old, body mass index of 43.8 ± 5.7 kg/m2, and median A1c of 5.9 [5.8, 6.1]%. After bariatric surgery, prediabetes remission rate was 82%, 73%, 66%, and 58%, respectively in the 1st, 2nd, 3rd, and 4th years of follow-up. Gastric sleeve (GS) surgery was associated with higher prediabetes remission rate than Roux-en-Y gastric bypass surgery in the 3rd year of follow-up. Men had a higher remission rate than women, in the 1st and 3nd years of follow-up in the unadjusted analysis. Younger patients presented a higher remission rate comparing to older patients in the 3rd year of follow-up. CONCLUSION: We showed a high prediabetes remission rate after bariatric surgery. The remission rate decreases over the follow-up period, although most of the patients maintain the normoglycemia. Prediabetes remission seems to be more significant in patients who had undergone GS, in male and in younger patients.

Vaccine-carditis study: Spanish multicenter registry of inflammatory heart disease after COVID-19 vaccination.

INTRODUCTION AND OBJECTIVES: Vaccines against SARS-CoV-2 have been a major scientific and medical achievement in the control of the COVID-19 pandemic. However, very infrequent cases of inflammatory heart disease have been described as adverse events, leading to uncertainty in the scientific community and in the general population. METHODS: The Vaccine-Carditis Registry has included all cases of myocarditis and pericarditis diagnosed within 30 days after COVID-19 vaccination since August 1, 2021 in 29 centers throughout the Spanish territory. The definitions of myocarditis (probable or confirmed) and pericarditis followed the consensus of the Centers for Disease Control and the Clinical Practice Guidelines of the European Society of Cardiology. A comprehensive analysis of clinical characteristics and 3-month evolution is presented. RESULTS: From August 1, 2021, to March 10, 2022, 139 cases of myocarditis or pericarditis were recorded (81.3% male, median age 28 years). Most cases were detected in the 1st week after administration of an mRNA vaccine, the majority after the second dose. The most common presentation was mixed inflammatory disease (myocarditis and pericarditis). 11% had left ventricular systolic dysfunction, 4% had right ventricular systolic dysfunction, and 21% had pericardial effusion. In cardiac magnetic resonance studies, left ventricular inferolateral involvement was the most frequent pattern (58%). More than 90% of cases had a benign clinical course. After a 3-month follow-up, the incidence of adverse events was 12.78% (1.44% mortality). CONCLUSIONS: In our setting, inflammatory heart disease after vaccination against SARS-CoV-2 predominantly affects young men in the 1st week after the second dose of RNA-m vaccine and presents a favorable clinical course in most cases.

COVID-19 Lockdown and Impact on 2-Year Weight Loss in a Bariatric Center.

INTRODUCTION: The COVID-19 pandemic has led to a worldwide lockdown, which affected physical exercise habits, as well as having a detrimental effect on psychological health and follow-up visits of patients submitted to bariatric surgery. The aim of this study was to evaluate the impact of COVID-19 lockdown on the 2-year weight loss of patients submitted to bariatric surgery in our center. METHODS: This was an observational study comparing the weight loss of patients who underwent bariatric surgery from January to March 2020 with a control group submitted to surgery between January and March 2017. Percentage of total weight loss (% TWL) and excess weight loss (% EWL) were assessed 6, 12, and 24 months after surgery. RESULTS: A total number of 203 patients were included in this study, 102 had bariatric surgery during the selected period in 2020 and 101 underwent surgery during the same period in 2017. There was no statistically significant difference in weight loss between the 2017 and 2020 groups which was reported as % TWL (mean 27.08 ± 7.530 vs. 28.03 ± 7.074, 33.87 ± 8.507 vs. 34.07 ± 8.979 and 34.13 ± 9.340 vs. 33.98 ± 9.993; p = 0.371) and % EWL (mean 66.83 ± 23.004 vs. 69.71 ± 17.021, 83.37 ± 24.059 vs. 84.51 ± 21.640 and 83.47 ± 24.130 vs. 84.27 ± 23.651; p = 0.506) at 6, 12, and 24 months post-surgery. CONCLUSION: Despite social limitations imposed by the COVID-19 lockdown, we found no significant difference between weight loss at 2 years postoperatively in the 2020 group when compared with a control group who underwent bariatric surgery in 2017. These results show that the outcomes of bariatric surgery during the COVID-19 lockdown were comparable with those recorded before the pandemic, supporting the efficacy of bariatric procedures' metabolic effects during the first 2 years after surgery, regardless of lifestyle habits.

Oil spill environmental sensitivity mapping of Rio de Janeiro, Brazil.

The current case study focuses on the Environmental Sensitivity Index (ESI) mapping of Guanabara Bay, Rio de Janeiro, Brazil - a region at risk from petroleum sector pollution. By mapping 981.5 km of coastline and classifying it in 10 oil sensitivity indices, we integrated biotic resources, socioeconomic attributes, and geoenvironmental diversity into a georeferenced database. Results reveal a high oil sensitivity of the bay, with approximately 89 % of the mapped coast scoring ESI 8 and ESI 10. These scores comprise, respectively, estuarine and solid substrate habitats that are sheltered from wave action. Notably, numerous manufacturing and oil handling plants, along with intensive urbanization, also contribute to the bay's oil sensitivity. Additionally, the rich biotic diversity in the study area, particularly in protected areas housing 79 conservation units, further amplifies its environmental vulnerability. This study aims to serve as a reference for detailed ESI mapping of coastal areas in tropical rainy zones with significant environmental diversity, industrial development, and a dense population.

Anthropogenic debris ingestion in a tropical seabird community: Insights from taxonomy and foraging distribution.

Oceans have been considered as an unlimited supply of goods and services, but resource extraction and waste disposal became ubiquitous and have been damaging the health of marine ecosystems. Finding suitable sentinel species of the human impacts on the oceans is thus imperative, since they may work as early warnings of disruptive situations. In this study, we investigated how taxonomy and foraging distribution influenced the occurrence of anthropogenic debris among five seabird species inhabiting the tropical Atlantic region. Occurrence of anthropogenic debris was assessed using faeces of breeding individuals as a proxy of ingestion. A total of 268 particles were extracted from all samples. The categories "fragments" and "fibres", as well as the colour "blue", were the most prevalent characteristics across species. There was a high diversity of polymers from cellulosic particles to synthetic plastics (Anthropogenic Cellulosic 26.9 %; Polyester 7.7 %; Varnish 5.8 %; Polypropylene 1.9 %). Species with a more coastal foraging strategy exhibited higher occurrence and number of anthropogenic debris when compared to species foraging comparably more in pelagic areas. This suggests that anthropogenic debris are more prevalent in coastal foraging areas, where human activities occur in higher number and frequency (e.g., fisheries) and sources of freshwater input from inland are at close distance. These results provide more evidence to the growing perception on the ubiquity and diversity of anthropogenic debris in the marine environment, and further support the usefulness of using seabirds as bio-indicators of anthropogenic pollution in both neritic and oceanic regions.

Pleobot: a modular robotic solution for metachronal swimming.

Metachronal propulsion is widespread in aquatic swarming organisms to achieve performance and maneuverability at intermediate Reynolds numbers. Studying only live organisms limits our understanding of the mechanisms driving these abilities. Thus, we present the design, manufacture, and validation of the Pleobot-a unique krill-inspired robotic swimming appendage constituting the first platform to study metachronal propulsion comprehensively. We combine a multi-link 3D printed mechanism with active and passive actuation of the joints to generate natural kinematics. Using force and fluid flow measurements in parallel with biological data, we show the link between the flow around the appendage and thrust. Further, we provide the first account of a leading-edge suction effect contributing to lift during the power stroke. The repeatability and modularity of the Pleobot enable the independent manipulation of particular motions and traits to test hypotheses central to understanding the relationship between form and function. Lastly, we outline future directions for the Pleobot, including adapting morphological features. We foresee a broad appeal to a wide array of scientific disciplines, from fundamental studies in ecology, biology, and engineering, to developing new bio-inspired platforms for studying oceans across the solar system.

Antitumor Profile of Combined Matricaria recutita Flower Extract and 5-Fluorouracil Chemotherapy in Sarcoma 180 In Vivo Model.

Medicinal plants have been commonly associated with chemotherapeutic treatments, as an approach to reduce the toxicological risks of classical anticancer drugs. The objective of this study was to evaluate the effects of combining the antineoplastic drug 5-fluorouracil (5-FU) with Matricaria recutita flowers extract (MRFE) to treat mice transplanted with sarcoma 180. Tumor inhibition, body and visceral mass variation, biochemical, hematological, and histopathological parameters were evaluated. The isolated 5-FU, 5-FU+MRFE 100 mg/kg/day, and 5-FU+MRFE 200 mg/kg/day reduced tumor growth; however, 5-FU+MRFE 200 mg/kg/day showed a more significant tumor reduction when compared to 5-FU alone. These results corroborated with the analysis of the tumor histopathological and immunodetection of the Ki67 antigen. In the toxicological analysis of the association 5-FU+MRFE 200 mg/kg/day, an intense loss of body mass was observed, possibly as a result of diarrhea. In addition, spleen atrophy, with a reduction in white pulp, leukopenia and thrombocytopenia, was observed in the 5-FU groups alone and associated with MRFE 200 mg/kg/day; however, there was no statistical difference between these groups. Therefore, the MRFE 200 mg/kg/day did not interfere in myelosuppressive action of 5-FU. In hematological analysis, body and visceral mass variation and biochemical parameters related to renal (urea and creatinine) and cardiac (CK-MB) function, no alteration was observed. In biochemical parameters related to liver function enzymes, there was a reduction in aspartate transaminase (AST) values in the 5-FU groups alone and associated with MRFE 200 mg/kg/day; however, there was no statistical difference between these groups. Therefore, the MRFE 200 mg/kg/day does not appear to influence enzyme reduction. The results of this study suggest that the association between the 5-FU+MRFE 200 can positively interfere with the antitumor activity, promoting the antineoplastic-induced reduction in body mass, while minimizing the toxicity of chemotherapy.

Fipronil affects cockroach behavior and olfactory memory.

Fipronil (Fpl), an insecticide belonging to the class of phenylpyrazoles, is associated with the widespread mortality of pollinator insects worldwide. Based on studies carried out on residual concentrations of Fpl commonly found in the environment, in this study, we evaluated the sublethal effects of Fpl on behavior and other neurophysiological parameters using the cockroach Nauphoeta cinerea as a biological model. Sublethal doses of Fpl (0.1-0.001 µg g-1) increased the time spent grooming and caused dose-dependent inhibition of exploratory activity, partial neuromuscular blockade in vivo and irreversible negative cardiac chronotropism. Fpl also disrupted learning and olfactory memory formation at all doses tested. These results provide the first evidence that short-term exposure to sublethal concentrations of Fpl can significantly disrupt insect behavior and physiology, including olfactory memory. These findings have implications for current pesticide risk assessment and could be potentially useful in establishing a correlation with pesticide effects in other insects, such as honey bees.

Family Conferences to Facilitate Deprescribing in Older Outpatients With Frailty and With Polypharmacy: The COFRAIL Cluster Randomized Trial.

Importance: For older adults with frailty syndrome, reducing polypharmacy may have utility as a safety-promoting treatment option. Objective: To investigate the effects of family conferences on medication and clinical outcomes in community-dwelling older adults with frailty receiving polypharmacy. Design, Setting, and Participants: This cluster randomized clinical trial was conducted from April 30, 2019, to June 30, 221, at 110 primary care practices in Germany. The study included community-dwelling adults aged 70 years or older with frailty syndrome, daily use of at least 5 different medications, a life expectancy of at least 6 months, and no moderate or severe dementia. Interventions: General practitioners (GPs) in the intervention group received 3 training sessions on family conferences, a deprescribing guideline, and a toolkit with relevant nonpharmacologic interventions. Three GP-led family conferences for shared decision-making involving the participants and family caregivers and/or nursing services were subsequently held per patient at home over a period of 9 months. Patients in the control group received care as usual. Main Outcomes and Measures: The primary outcome was the number of hospitalizations within 12 months, as assessed by nurses during home visits or telephone interviews. Secondary outcomes included the number of medications, the number of European Union list of the number of potentially inappropriate medication (EU[7]-PIM) for older people, and geriatric assessment parameters. Both per-protocol and intention-to-treat analyses were conducted. Results: The baseline assessment included 521 individuals (356 women [68.3%]; mean [SD] age, 83.5 [6.17] years). The intention-to-treat analysis with 510 patients showed no significant difference in the adjusted mean (SD) number of hospitalizations between the intervention group (0.98 [1.72]) and the control group (0.99 [1.53]). In the per-protocol analysis including 385 individuals, the mean (SD) number of medications decreased from 8.98 (3.56) to 8.11 (3.21) at 6 months and to 8.49 (3.63) at 12 months in the intervention group and from 9.24 (3.44) to 9.32 (3.59) at 6 months and to 9.16 (3.42) at 12 months in the control group, with a statistically significant difference at 6 months in the mixed-effect Poisson regression model (P = .001). After 6 months, the mean (SD) number of EU(7)-PIMs was significantly lower in the intervention group (1.30 [1.05]) than in the control group (1.71 [1.25]; P = .04). There was no significant difference in the mean number of EU(7)-PIMs after 12 months. Conclusions and Relevance: In this cluster randomized clinical trial with older adults taking 5 or more medications, the intervention consisting of GP-led family conferences did not achieve sustainable effects in reducing the number of hospitalizations or the number of medications and EU(7)-PIMs after 12 months. Trial Registration: German Clinical Trials Register: DRKS00015055.

Amyloidosis Localized to the Sinonasal Tract: From the Diagnosis to Management of Disease.

Amyloidosis is a mainly systemic rare disease and its localized presentation is even less frequent. Systemic forms are often associated with other conditions or entities (such as neoplasms), and a correct etiological study of patients with this disease is essential. A localized presentation has a better prognosis compared to systemic forms, which underlines the importance of a correct diagnosis. Primary localized amyloidosis in the head and neck region is a rare entity. Primary amyloidosis localized to the sinonasal tract is extremely rare. Although uncommon, case reports have been increasing in the face of new endoscopic and imaging techniques, and the report of these cases is crucial for a better characterization of this entity. Symptoms may include epistaxis, nasal obstruction, facial deformity, and vision changes. A 72-year-old female with a history of frequent nasal congestion with two years' duration showed no improvement following symptom management. She was referred for nasal endoscopy and biopsy, thereby confirming the diagnosis of amyloidosis. Further diagnostic testing did not show evidence of systemic disease. This case report was previously presented as a poster presentation at the 19th European Congress of Internal Medicine in March 2021.

Capacidade de deglutição e gravidade do risco de aspiração laringotraqueal no Acidente Vascular Encefálico atípico em via cerebelar: relato de caso / Swallowing capacity and gravity of the laryngotracheal aspiration risk in atypical cerebellar stroke: case report

RESUMO Esse relato de caso teve o objetivo de avaliar a capacidade de deglutição e a gravidade do risco de aspiração laringotraqueal de uma paciente, 52 anos, com Acidente Vascular Encefálico (AVE) atípico, com comprometimento na via cerebelar. Para mensurar a capacidade de deglutição e do risco de aspiração foram utilizados a avaliação de rotina na clínica de fonoaudiologia e dois testes clínicos validados: o Massey Bedside Swallowing Screen (MBSS) e o Gugging Swallowing Screen (GUSS). Após a avaliação com os testes clínicos, foi observado que a paciente apresentou capacidade de deglutição diminuída, desempenho caracterizado como patológico e de risco, com 100% de alteração no teste de deglutição de água pelo MBSS, presença de engasgo, tosse, alteração na qualidade vocal e escape anterior de alimento. Já na avaliação do risco de aspiração com o GUSS, a paciente apresentou disfagia moderada e com risco de aspiração laringotraqueal. A disfagia pode estar presente em casos de AVE com lesão anatômica comprometendo o cerebelo e suas vias, o que sugere a importância de avaliação específica da deglutição nesses casos. Os testes GUSS e o MBSS podem ser utilizados para avaliação de casos atípicos de AVE em fase ambulatorial, com objetivos de avaliar o risco de aspiração e a capacidade de deglutição.

ABSTRACT This case report aimed to evaluate the swallowing capacity and the severity of the risk of laryngotracheal aspiration of a 52-year-old female patient with atypical and rare stroke, with major injury in the cerebellar pathway. In order to measure swallowing capacity and risk of aspiration a routine clinical assessment used in the speech therapy clinic was performed and two valid clinical tests were used: Massey Bedside Swallowing Screen (MBSS) and Gugging Swallowing Screen (GUSS). After evaluation with the clinical tests, it was observed that the patient had reduced swallowing capacity, performance characterized as pathological, 100% dysfunction in the water swallowing test (MBSS), presence of choking, coughing, change in vocal quality and anterior escape. In the assessment of risk of aspiration with the GUSS, the patient presented moderate dysphagia and risk of laryngotracheal aspiration.This case report demonstrated that moderate dysphagia is found in a stroke patient with lesions that affect the cerebellum. Standardized and validated clinical tests such as GUSS and MBSS should also be used to assess the risk of dysphagia after stroke at ambulatory care.

Development of a deprescribing manual for frail older people for use in the COFRAIL study and in primary care.

Introduction: Many older adults are affected by multimorbidity and subsequent polypharmacy which is associated with adverse outcomes. This is especially relevant for frail older patients. Polypharmacy may be reduced via deprescribing. As part of the complex intervention in the COFRAIL study, we developed a deprescribing manual to be used by general practitioners (GPs) in family conferences, in which GPs, patients and caregivers jointly discuss treatments. Methods: We selected indications with a high prevalence in older adults in primary care (e.g. diabetes mellitus, hypertension) and conducted a literature search to identify deprescribing criteria for these indications. We additionally reviewed clinical practice guidelines. Based on the extracted information, we created a deprescribing manual which was then piloted in an expert workshop and in family conferences with volunteer patients according to the inclusion and exclusion criteria of the study protocol. Results: Initially, 13 indications/topics were selected. The literature search identified deprescribing guides, reviews and clinical trials as well as lists of potentially inappropriate medication and systematic reviews on the risk and benefits of specific drugs and drug classes in older patients. After piloting and revisions, the deprescribing manual now covers 11 indications/topics. In each chapter, patient- and medication-related deprescribing criteria, monitoring and communication strategies, and information about concerns related to the use of specific drugs in older patients are provided. Discussion: We found varying deprescribing strategies in the literature, which we consolidated in our deprescribing manual. Whether this approach leads to successful deprescribing in family conferences is being investigated in the cluster-randomised controlled COFRAIL study. Plain Language Summary: Development of a manual to help doctors to identify which medications can be withdrawn Many older adults suffer from chronic diseases and take multiple medications concurrently. This can lead to side effects and other undesired events. We developed a manual to help doctors identify which medications can be withdrawn, so that they can discuss this with their patients. This manual was used in the COFRAIL study where doctors, patients and caregivers met in family conferences to discuss their preferences and decide together how future treatments should be handled. The manual contains information on common medications, symptoms and diseases in older patients such as diabetes and high blood pressure. Before the manual was used in the study, it was tested by volunteer patients and their doctors and caregivers to make sure that it is user-friendly.

A 68-Year-Old Woman Presenting with Recurrent Abdominal Pain and a Diagnosis of a Presacral Retroperitoneal Benign Schwannoma that Mimicked an Ovarian Tumor on Pelvic Magnetic Resonance Imagining.

BACKGROUND Schwannomas are benign tumors and their appearance in the pelvic region is rare and poses a major diagnostic problem. They can be sporadic or associated with genetical syndromes. They have a slow growth rate and may be asymptomatic for many years. Symptoms are usually nonspecific and due to compression of adjacent structures. Abdominal imaging modalities may not be able to differentiate a benign schwannoma from a malignant retroperitoneal tumor. This report is of a case of a 68-year-old woman presenting with recurrent abdominal pain and a diagnosis of a presacral retroperitoneal benign schwannoma that mimicked an ovarian tumor on pelvic magnetic resonance imaging. CASE REPORT The patient had a history of a femoral hernia repair and recurrent lower abdominal pain. Pelvic imaging raised the suspicion of a primary ovarian tumor. The mass appeared to have clear cleavage planes with the surrounding structures, so the patient was proposed for an exploratory laparotomy. Prior to the surgery, an additional pelvic computed tomography (CT) was performed (10 months after the first one), which did not show progression of the disease. The histological examination result was compatible with a benign retroperitoneal schwannoma and not an ovarian tumor. CONCLUSIONS This report highlights that the diagnosis of retroperitoneal and pelvic masses can be challenging. In women, a primary ovarian tumor should be excluded on imaging and the diagnosis of a benign tumor, such as schwannoma, must be confirmed by histopathology, either preoperatively or following tumor resection.

Impact of Particles on Pulmonary Endothelial Cells.

According to the WHO, air quality affects around 40 million people, contributing to around 21,000 premature deaths per year. Severe respiratory diseases, such as asthma and chronic obstructive pulmonary disorder, can be promoted by air pollution, which has already been documented; this is one of the reasons why air quality is a very relevant factor for human health and well-being. Aerosols are an aggregation of solid or liquid particles dispersed in the air and can be found in the form of dust or fumes. Aerosols can be easily inhaled or absorbed by the skin, which can lead to adverse health effects according to their sizes that range from the nanometre to the millimetre scale. Based on the PRISMA methodology and using the Rayyan QCRI platform, it was possible to assess more than four hundred research articles. This systematic review study aimed to understand the impact of particles on pulmonary endothelial cells, namely particulate matter in different sizes, cigarette smoke, diesel exhaust particles and carbon black. The main conclusions were that particles induce multiple health effects on endothelial cells, namely endothelial dysfunction, which can lead to apoptosis and necrosis, and it may also cause necroptosis in lung structure.

Excessive tooth wear on human dental enamel: a case report / Desgaste excessivo em esmalte dentário humano: relato de caso

Introduction: although reports on dental erosion have appeared in literature for a long time, there is currently a growing interest among researchers and clinicians about this matter. Potential risk factors for loss of dental hard tissue are changed lifestyle and eating patterns, with increased consumption of acid foods and beverages. Case report: an atypical tooth wear on the buccal surfaces of the mandibular teeth in a 45-year-old woman referred for orthodontic treatment, associated with the frequent consumption of whiskey and lemon, is reported. A comprehensive approach, such as the recognition of dental erosion joined with a careful investigation about eating habits was performed. Ultrastructural examination of replicas of the teeth showed practically structureless enamel and dentin surfaces. Conclusion: the screening for dental erosion in patients seeking orthodontic treatment is advisable to be a usual procedure. Recommendations for treatment and prophylactic measures are made emphasizing the need of multiprofessional attention.

Introdução: embora relatos sobre erosão dentária já apareçam há bastante tempo na literatura, existe atualmente interesse crescente entre pesquisadores e clínicos sobre esse assunto. Fatores que representam riscos potenciais para a perda de tecido duro do dente são as mudanças no estilo de vida e no padrão de alimentação, com o aumento no consumo de alimentos e bebidas ácidas. Relato de caso: lesões atípicas de desgaste dentário na superfície vestibular das unidades inferiores, em uma mulher com 45 de idade, encaminhada para tratamento ortodôntico, associadas ao consumo frequente de uísque e limão, foram relatadas. Uma abordagem abrangente, como o reconhecimento da erosão dentária, em conjunção com a investigação cuidadosa dos hábitos alimentares, foi realizada. O exame por meio da microscopia eletrônica de varredura, realizada em réplicas dos dentes, revelou superfícies de esmalte e dentina praticamente desprovidos de elementos estruturais. Conclusão: sugere-se que uma avaliação direcionada à busca por erosão dentária em pacientes que procuram por tratamento ortodôntico seja um procedimento rotineiro. A atenção multiprofissional, envolvendo o tratamento e o uso de medidas preventivas, é essencial para a adequada atuação junto ao paciente.
