Objective: To evaluate whether intrathecal chemotherapy improves clinical outcomes in patients with meningeal carcinomatosis.
Methods: This retrospective cohort study included consecutive patients with breast cancer diagnosed with meningeal carcinomatosis. Clinical and treatment data were collected from the patients' medical charts. The primary outcome was overall survival, and the secondary outcomes were time to neurological deterioration and reporting of clinical benefit. Logistic regression and Cox proportional hazard models adjusted for potential confounders were used to evaluate the clinical response and overall survival, respectively.
Results: Overall, 109 female patients were included, 50 (45.9%) of whom received intrathecal chemotherapy with methotrexate and dexamethasone. The median treatment duration was 3 weeks (range, 1-13 weeks). Patients treated with intrathecal chemotherapy were more likely to report clinical benefit (74% versus 57.7%, adjusted odds ratio [OR] = 9.0, 95%CI=2.6-30.9, p<0.001). However, there was no difference in the time to neurologic deterioration (hazard ratio [HR] = 0.96, 95%CI= 0.57-1.59, p=0.86). Patients who received intrathecal chemotherapy did not show an increase in overall survival compared with that of patients who did not receive intrathecal chemotherapy (median overall survival = 1.8 months, 95%CI= 1.27-3.0 versus 2.5, 95%CI= 1.9-3.9, adjusted HR = 0.71, 95%CI= 0.41-1.22, p=0.21). There was a significant interaction between intrathecal chemotherapy and systemic treatment, and patients who received systemic therapy without intrathecal chemotherapy had better overall survival than that of the no-treatment group (adjusted HR = 0.38, 95%CI= 0.20-0.70, p=0.002).
Conclusion: Intrathecal chemotherapy did not increase overall survival or time to neurological deterioration and should not preclude or postpone systemic treatments.

Objective: To assess the incidence of febrile neutropenia without primary granulocyte colony-stimulating factor prophylaxis in patients undergoing chemotherapy with adjuvant docetaxel and cyclophosphamide, and to evaluate the toxicity profile of brand-name docetaxel (Taxotere ® ) and the generic formulation.
Methods: This retrospective study was conducted using data obtained from electronic medical records of patients treated at a Brazilian cancer center. Patients with breast cancer who underwent adjuvant treatment between January 2016 and June 2019 were selected. Data were analyzed using chi-square and Fisher correlation of variables, and multivariate analyses were adjusted for propensity score.
Results: A total of 231 patients with a mean age of 55.9 years at the time of treatment were included in the study. The majority (93.9%) had luminal histology, 84.8% were at clinical stage I, and 98.2% had a good performance status. The overall incidence of febrile neutropenia in the study population was 13.4% (31 cases). The use of brand-name docetaxel (Taxotere ® ) was the only factor associated with febrile neutropenia occurrence (OR= 3.55, 95%CI= 1.58-7.94, p=0.002).
Conclusion: In patients with breast cancer who require treatment with adjuvant docetaxel and cyclophosphamide regimen, the toxicity profile differs between brand-name and generic docetaxel. Regardless of the formulation used, the incidence of febrile neutropenia was less than 20%, which may allow for the omission of primary prophylactic granulocyte colony-stimulating factor use in this setting.

Objective: To establish the diagnostic performance of fine-needle aspiration in detecting benign and malignant neoplasm in comparison with post-thyroidectomy histopathological findings among patients who received a thyroidectomy.
Methods: Retrospective observational data collected between 2011-2021 were included from patients who received partial or total thyroidectomy. The Bethesda system was used to classify neoplasms from fine-needle aspiration procedures as benign or malignant. Sample characteristics, diagnostic accuracy, sensitivity, specificity, and predictive values were evaluated.
Results: Patients (n=360) who underwent thyroidectomy were analyzed, of whom 142 (39.4%) and 218 (60.6%) had benign and malignant neoplasms, respectively. Using the Bethesda system, 23 (6.4%) were classified as unsatisfactory result (BI), 83 (23.1%) as benign (BII), 50 (13.9%) as atypia of undetermined significance (BIII), 23 (6.4%) as suspected follicular or Hürthle cell neoplasia (BIV), 102 (28.3%) as suspected malignancy (BV) and 79 (21.9%) as malignant (BVI). The fine-needle aspiration diagnostic accuracy for carcinomas was 92%, while the sensitivity and specificity were 94.4% and 86.9%, respectively. The negative and positive predictive values were 87.9% and 93.9%, respectively.
Conclusion: Fine-needle aspiration has high diagnostic accuracy, sensitivity and specificity, and is a reliable test for distinguishing between benign and malignant thyroid pathologies.

This program was conducted in partnership with Volunteering and Escola Municipal de Ensino Fundamental Professor Paulo Freire in Paraisópolis, São Paulo, Brazil. The Scientists of Tomorrow Program comprised a short training period conducted in May 2022 involving 37 students, and a long training period from August to December 2022, which included 15 students. It aimed to popularize science through practical activities; transfer knowledge to young students; sensitize and guide them to pursue academic-scientific careers; reduce stereotypes about scientific work and scientists; and help students understand the social, political, and ethical roles of science within society. All activities were led by postgraduate students and professors from our postgraduate program, physicians, nurses, physiotherapists, biomedicals, and veterinarians from Hospital Israelita Albert Einstein, as well as medical students from Faculdade Israelita de Ciências da Saúde Albert Einstein . Activities in the short training included lectures on cinema and science, strategies to combat fake news, non-violent communication, innovation, design-thinking framework, and developing a scientific project. During the long training period, discussions were focused on nanotechnology, animal research, big data, bioinformatics, meditation, blood and bone marrow donation, telemedicine, sex and sexually-transmitted infections, rehabilitation, career opportunities, and scientific integrity. In addition, practical activities were further expanded using optical and confocal microscopy, cytometry, and basic concepts regarding the structure and function of living cells. The program also included the launching of the open-air outreach Education E-natureza activity, which turned students into ambassadors of nature. In conclusion, the Scientists of Tomorrow Program was innovative and enabled young students to learn that science is a collective activity that can enhance public health.

Objective: To describe the clinical, bronchoscopic, diagnostic, and therapeutic aspects between children and adults.
Methods: This retrospective study compared the clinical and bronchoscopic characteristics of adults and children who underwent bronchoscopy for suspected foreign body aspiration. Data on sex, outpatient or emergency origin, bronchoscopy results, characteristics of the aspirated foreign body, and complications were analyzed.
Results: In total, 108 patients were included in the analysis, with foreign body aspiration diagnosed in 69% of patients (30 children and 44 adults). In 91% of patients, there was a clinical history suggestive of aspiration. The mean age of the adults was 65.89 (±19.75) years, and that of the children was 2.28 (±1.78) years. Most of the children were under 3 years of age (80%), while adults were mostly 70 years of age or older (54.5%). Emergency care was more common among children than adults. The most common foreign bodies found in both age groups were organic bodies, primarily seeds. The most frequent locations of foreign bodies were the lobar bronchi in adults and the main bronchi in children. Flexible bronchoscopy is the primary method for diagnosis and treatment. Transient hypoxemia occurred particularly frequently in children (5%).
Conclusion: Foreign body aspiration, particularly that involving seeds, is more common in the extremes of age. A clinical history suggestive of aspiration is crucial in determining the need for bronchoscopy, which should be performed as early as possible. Flexible bronchoscopy is an effective and safe diagnostic technique.

Background: Miyasato et al. show that peak oxygen consumption, walking economy, anaerobic threshold, and cardiovascular responses (heart rate, blood pressure, and rate pressure product) during walking were similar between men and women with peripheral artery disease and intermittent claudication. There were no differences in the physiological responses to walking between men and women with intermittent claudication. Sex per se is not a factor that demands changes in walking prescription for patients with intermittent claudication.
Objective: Peak oxygen consumption (VO2peak), anaerobic threshold, walking economy, and cardiovascular responses during walking are used to guide and monitor walking training in patients with peripheral artery disease and intermittent claudication. Women with peripheral artery disease and intermittent claudication present greater impairments than men, and evaluating training markers according to sex for decisions regarding walking prescription in this population is important. This study aimed to compare VO2peak, walking economy, anaerobic threshold, and cardiovascular responses during walking in men and women with peripheral artery disease and intermittent claudication.
Methods: Forty patients (20 men and 20 women with similar baseline characteristics) underwent a cardiopulmonary treadmill test (3.2km/h and 2% increase in slope every 2 minutes until maximal leg pain). The VO2 and rate-pressure product were assessed. Data from men and women were compared using t-tests.
Results: There were no significant differences between men and women (VO2peak: 15.0±4.8 versus 13.9±2.9mL∙kg-1∙min-1, p=0.38; walking economy: 9.6±2.7 versus 8.4±1.6mL∙kg-1∙min-1, p=0.09; anaerobic threshold: 10.5±3.2 versus 10.5±2.2mL∙kg-1∙min-1, p=0.98; rate pressure product at 1st stage: 13,465± 2,910 versus 14,445±4,379bpm∙mmHg, p=0.41; and rate pressure product at anaerobic threshold:13,673±3,100 versus 16,390±5,870bpm∙mmHg, p=0.08 and rate pressure product at peak exercise: 21,253±6,141 versus 21,923±7,414bpm∙mmHg, p=0.76, respectively).
Conclusion: Men and women with peripheral artery disease and similar baseline characteristics presented similar responses to walking, suggesting that decisions regarding walking prescription and monitoring can be made regardless of sex in this specific population.

Pulmonary aspiration of gastric residues during anesthesia is a potentially fatal complication for which no specific treatment is available. The primary way to prevent its occurrence in the context of elective surgeries is adherence to fasting protocols. However, some clinical conditions can prolong the gastric emptying time, and the risk of aspiration may exist despite adequate fasting. Recognizing the risk factors for gastroparesis allows the adoption of preventive methods and is the primary way to reduce morbidity and mortality from pulmonary aspiration. In this scenario, the anesthesiologist can investigate the gastric content by using ultrasound, adjust the anesthetic technique, and even postpone elective surgeries. Here, we describe incidental computed tomography finding of solid contents in the stomach of a patient without prior identification of the risk factors for gastroparesis. The patient underwent elective renal nodule ablation under general anesthesia after fasting for 9 hours. During the procedure, solid contents in the stomach were noted on computed tomography. Subsequently, it was discovered that the patient had been using semaglutide for 6 days and had not disclosed this information. Semaglutide use may represent a new and significant risk factor for anesthesia-related pulmonary aspiration. Until studies provide information on the appropriate perioperative management of patients using semaglutide, anesthesiologists need to adopt preventive measures to avoid aspiration. Awareness of this potential association and open communication among patients, physicians, and anesthesia teams are essential for enhancing patient safety.

Background: Borim et al. showed that older adults with chronic pain exhibited more depressive symptoms and frailty components. Depressive symptoms were associated with more frailty components, and those with more depressive symptoms and frailty faced greater limitations in IADL performance. Frailty appears to mediate the pathway from chronic pain to functional impairment Chronic pain is directly associated with depressive symptoms and frailty. Chronic pain is not directly associated with functional disability. Depression and frailty are both directly associated with functional disabilities. Frailty mediates the association between chronic pain and functional disability. Depression; Disability evaluation; Frailty; Frail elderly.
Objective: To evaluate the direct and indirect effects of chronic pain, depressive symptoms, frailty components, and functional disability through a pathway analysis approach in a sample of community-dwelling older adults.
Methods: Data of 419 participants were cross-sectionally evaluated for the presence of depressive symptoms (Geriatric Depression Scale [15 items]), physical frailty components (phenotype criteria), chronic pain, and limitations in performing instrumental activities of daily living (functional disability scale by Lawton and Brody). Structural equation modeling via path analysis was used to explore the direct and indirect effects among these four variables. Statistical significance was set at p<0.05.
Results: Of the total participants, 69.8% were women and 59.3% had low education (1-4 years); the mean age was 80.3±4.6 years. Chronic pain and depressive symptoms were directly related and were associated to frailty. The number of frailty components and depressive symptoms were directly associated with functional disability. Frailty had an indirect effect on the association between chronic pain, depressive symptoms, and functional disabilities.
Conclusion: The pathway from chronic pain and depressive symptoms to functional disability is potentially mediated by the number of frailty components.

Molecular imaging markers can be used to differentiate between infection and aseptic inflammation, determine the severity of infection, and monitor treatment responses. One of these markers is ubiquicidin(29-41) (UBI), a cationic peptide fragment that binds to the bacterial membrane wall and is labeled with gallium-68 (68Ga), a positron emitter radioisotope. The use of UBI in positron emission tomography (PET)/computed tomography (CT) for improved detection of lesions has been receiving considerable attention recently. Herein, we report the first case of 68Ga-UBI PET/CT performed in Brazil. The patient was a 39-year-old woman referred for a scan to confirm a clinical suspicion of chronic osteomyelitis of her fractured left tibia. PET images revealed radiotracer uptake near the posterior contour of the tibial fracture focus and the fixation plate, in the soft tissue around the distal half of the tibia, and in the non-consolidated fracture of the left distal fibula. Surgery for local cleaning was performed, and culture of a specimen collected from the surgical site confirmed the presence of Staphylococcus aureus. In the present case, 68Ga-UBI PET/CT, a non-invasive imaging modality, identified the infection foci in vivo, indicating its potential for clinical use.

Objective: We hypothesized that perinatal manipulations of the nitrergic system would affect adult animal behaviors.
Methods: We tested this hypothesis by perinatally administering N(G)-Nitro-L-arginine methyl ester (L-NAME), a non-specific antagonist of nitric oxide synthase for 15 days and assessed anxiety- and depression-like behaviors in adult mice. At 70 days of age, the mice were subjected to a battery of tests consisting of the open-field, light/dark box, forced swim, and tail-flick tests. The tests were performed at two-day intervals, and the order of the tests within the battery was determined according to the progressive invasiveness degree.
Results: L-NAME-treated animals exhibited decreased anxiety-like behavior in the light/dark box and open field tests, with no change in locomotor activity. Additionally, they demonstrated decreased depression-like behavior in the forced swim test and no change in pain perception in the tail-flick test.
Conclusion: The nitrergic system is possibly involved in neural circuitry development that regulates behaviors since blocking perinatal nitric oxide production decreases anxiety- and depression-like behaviors in adult mice.
