Assessment Modalities for Lower Extremity Edema, Lymphedema, and Lipedema: A Scoping Review.

Lower extremity swelling may be broadly characterized as due to edema, lymphedema, or lipedema. Differentiation between these three conditions is important for providing appropriate treatment. This review analyzes and compares different clinical diagnostic modalities for these conditions, with the aim of assisting in the process of choosing the most appropriate diagnostic modality by highlighting the advantages and limitations of each. Using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines for a systematic search of peer-reviewed literature, the following diagnostic methods for lower extremity swelling were investigated: (1) ultrasound (US), (2) lymphoscintigraphy (LSG), (3) computed tomography (CT), (4) bioimpedance spectroscopy (BIS), (5) tissue dielectric constant (TDC), and (6) magnetic resonance imaging (MRI), including magnetic resonance lymphangiography (MRL). The databases used in the search were PubMed, ProQuest, CINAHL Complete, Web of Science, Embase, and Biomedical Reference Collection. After retrieving 115 studies based on predetermined inclusion criteria, a total of 31 studies were critically evaluated. The main results indicate the following: duplex US is the modality of choice to initially identify lower extremity edema such as deep venous thrombosis (DVT) and venous reflux due to its high sensitivity and specificity. CT venography of the lower extremity appears to bethe preferred option for gynecologic cancer patients with lower extremity swelling post-treatment, as it measures subcutaneous tissue volumes to look for DVTs, lymphoceles, and cancer recurrence. TDC is a recommended modality for a variety of conditions, including edema and lymphedema, in part, due to its noninvasive localized assessment capabilities and ease of use. LSG emerges as an effective imaging modality for lymphedema characterization with minimal invasiveness and high sensitivity and specificity. BIS is widely used to identify and monitor lower extremity lymphedema but has been reported to have low sensitivity and lacks the ability to account for changes in tissue composition such as fibrosis. US and MRL are favored for lipedema diagnosis, with MRL providing comprehensive anatomical and functional insights, albeit with cost and accessibility limitations compared to US. While CT, MRI, US, and TDC are all useful for differentiating lymphedema from lipedema, MRI is the preferred modality due to its anatomical and functional diagnostic capabilities. However, US is a pragmatic alternative for use with obese patients or when MRI is not an option.

Accelerative action of topical piperonylic acid on mice full thickness wound by modulating inflammation and collagen deposition.

Epidermal growth factor (EGF) promotes cell growth, proliferation, and survival in numerous tissues. Piperonylic acid, a metabolite present in peppers (Piper nigrum L. and Piper longum L.), can bind to the epidermal growth factor receptor (EGFR) and induce an intracellular signaling cascade leading to the transcription of genes responsible for these actions, especially in keratinocytes. These cells are fundamental in maintaining cutaneous homeostasis and are the first to be damaged in the case of a wound. Thus, we hypothesized that piperonylic acid improves wound healing. C57BL6/J male mice were submitted to dorsal skin wounds caused by a 6 mm punch and treated topically with piperonylic acid or vehicle. The wounds were evaluated macro- and microscopically, and tissue samples were collected for immunofluorescence and real-time PCR analyses on days 6, 9 and 19 post-injury. Topical piperonylic acid improved wound healing from day 6 post-injury until closure. This phenomenon apparently occurred through EGFR activation. In addition, piperonylic acid modulated the gene expression of interleukin (Il)-6, il-1ß, tumor necrosis factor (Tnf)-α, il-10, monocyte chemoattractant protein (Mcp)-1 and insulin-like growth factor (Igf)-1, which are important for the healing process. By day 19 post-injury, the new tissue showed greater deposition of type I collagen and a morphology closer to intact skin, with more dermal papillae and hair follicles. We conclude that piperonylic acid may be a viable option for the treatment of skin wounds.

A Smartphone App for Individual Xylazine/Ketamine Calculation Decreased Anesthesia-Related Mortality in Mice.

Currently, experimental animals are widely used in biological and medical research. However, the scientific community has raised several bioethical concerns, such as the number of animals required to achieve reproducible and statistically relevant results. These concerns involve aspects related to pain, discomfort, and unwanted animal loss. Retrospectively, we compare two different approaches for anesthesia dosage: a mobile app for dose calculation and a standard dose calculation. A total of 939 C57BL/6J and Swiss mice were analyzed. We collected data on intraoperative and anesthesia-related mortality as described in electronic or physical handwritten records. Our results showed that the mobile app approach significantly reduces anesthetic-related deaths upon using doses of ketamine and xylazine. The results suggest that anesthesia-related mortality can be minimized even more using information technology approaches, helping to solve an old but transversal challenge for researchers working with experimental mice. The mobile app is a free and open code which could be implemented worldwide as an essential requirement for all anesthetic procedures in mice using xylazine and ketamine combination. As an open code app, the Labinsane initiative could also represent the starting point to unify and validate other anesthetic procedures in different species and strains.

Consequences of Iodine Deficiency and Excess in Pregnancy and Neonatal Outcomes: A Prospective Cohort Study in Rio de Janeiro, Brazil.

Background: Insufficient or excessive iodine intake during gestation may compromise adaptive mechanisms in maternal thyroid function and lead to adverse pregnancy outcomes. In this context, we aimed to study the effects of maternal iodine status in the first and third trimesters of gestation on obstetric and neonatal outcomes in an iodine-sufficient population in Rio de Janeiro, Brazil. Methods: A total of 214 pregnant women in the first trimester of gestation were enrolled and prospectively followed until delivery between 2014 and 2017. All participants were ≥18 and ≤35 years, had a spontaneous single pregnancy, and had no history of thyroid or other chronic diseases, nor were they taking iodine-containing supplements at enrollment. In the first trimester, we obtained clinical information and determined thyroid function and the urinary iodine concentration (UIC) of the participants. Thyroid function and UIC were reassessed in the third trimester. Iodine status was determined by the median of UIC obtained from six urine spot samples by the inductively coupled plasma mass spectrometry method. Pregnancy and neonatal outcomes and delivery information were obtained from medical records. Results: The median UIC in the whole population was 219.7 µg/L. The prevalence of UIC <150 µg/L was 17.2%, and 38.7% had UIC ≥250 µg/L. Gestational diabetes (GDM) was higher in the group with UIC 250-499 µg/L (n = 77) compared with the group with UIC 150-249 µg/L (n = 94) (20.3% vs. 9.7%, p < 0.05). Ultimately, UIC ≥250 µg/L was an independent risk factors for GDM (relative risk [RR] = 2.9 [confidence interval, CI = 1.1-7.46], p = 0.027) and hypertensive disorders of pregnancy (HDP) (RR = 4.6 [CI = 1.1-18.0], p = 0.029). Among 196 live-born newborns, lower birth length was observed in infants whose mothers had UIC <150µg/L (n = 37) in the first trimester compared with those with UIC 150-249 µg/L (n = 86) (median interquartile range: 48.0 [2.2] vs. 49.0 [4.0] cm, p = 0.01). Maternal UIC <150 µg/L was negatively associated with birth length of newborns (Exp (B) = 0.33 [CI = 0.1-0.9], p = 0.03). Conclusions: In a population whose median iodine intake is sufficient, extensive individual variation occurs. Such abnormalities are associated with increased GDM and HDP when UIC is ≥250 µg/L, and lower infant birth length when UIC is <150 µg/L.

Selective case finding versus universal screening for detecting hypothyroidism in the first trimester of pregnancy: a comparative evaluation of a group of pregnant women from Rio de Janeiro.

Objective Maternal hypothyroidism during pregnancy may lead to adverse outcomes. Recently published guidelines by the American Thyroid Association (ATA) do not advocate for universal screening but recommend a case-finding approach in high-risk pregnant women. The present study aims to evaluate the accuracy of this approach in identifying women with thyroid dysfunction during early pregnancy. Subjects and methods This is a multiple-center, cross-sectional study. Three hundred and one pregnant women were enrolled. Anamnesis and a physical examination were performed to detect which women fulfilled the criteria to undergo laboratory screening of thyroid dysfunction, according to the ATA's 2017 guidelines. The Zulewski's validated clinical score was applied to assess signs and symptoms of hypothyroidism. Serum levels of thyrotropin (TSH), free thyroxine (FT4), anti-thyroperoxidase (TPO-Ab), and anti-thyroglobulin (Tg-Ab) antibodies were determined. Results Two hundred and thirty one women (78%) were classified as high risk, and 65 (22%) were classified as low risk for thyroid dysfunction. Regarding the clinical score, 75 patients (31.2%) presented mild symptoms that were compatible with SCH, of which 22 (7.4%) had symptoms as the only risk factor for thyroid disease. 17 patients (5.7%) had SCH, of which 10 (58.8%) belonged to the high-risk group, and 7 (41.2%) belonged to the low-risk group. OH was found in 4 patients (1.4%): 3 (75%) in the high-risk group and 1 (25%) in the low-risk group. Conclusions The ATA's proposed screening criteria were not accurate in the diagnosis of thyroid dysfunction in pregnancy. Testing only the high-risk pregnant women would miss approximately 40% of all hypothyroid patients.

Estado Nutricional de Pacientes Pediátricos Recém-Diagnosticados com Leucemia Linfoblástica Aguda em um Instituto de Referência em Oncologia do Rio de Janeiro / Nutritional Status of Pediatric Patients Newly Diagnosed with Acute Lymphoblastic Leukemia at an Institute of Reference in Oncology of Rio de Janeiro / Estado Nutricional de Pacientes Pediátricos Recién diagnosticados con leucemia linfoblástica Aguda en un Instituto de Referencia en Oncología de Río de Janeiro

Introdução: a leucemia linfoblástica aguda (lla) constitui a neoplasia mais comum em pediatria e a avaliação nutricional é um instrumento essencial para conhecer as condições de saúde dos pacientes. o presente estudo teve como objetivo avaliar e descrever o estado nutricional de pacientes pediátricos recém-diagnosticados com lla e verificar a relação do índice de massa corporal para idade (iMc/i) com as demais medidas antropométricas. Método: estudo observacional, transversal, realizado com pacientes de 1 a 18 anos, recém- -diagnosticados com lla, no período de janeiro/2004 a dezembro/2009. os dados coletados foram idade, peso corporal, estatura, prega cutânea tricipital (Pct), circunferência do braço (cB) e circunferência muscular do braço (cMB). o iMc foi calculado e a classificação iMc/i utilizada na análise. o teste Qui-quadrado de Pearson e exato de Fisher foram utilizados para analisar a associação entre os parâmetros antropométricos. Resultados: Foram incluídos no estudo 54 pacientes. a classificação do "estado nutricional adequado" foi a mais frequente em todos os parâmetros antropométricos. em adição, observou-se que a associação do estado nutricional pela cMB com o iMc/i (p=0,001) demonstra que este último pode ser adequado para classificação dos pacientes pediátricos com lla ao diagnóstico. e a concordância da cB com a cMB (p=0,01) de 43% (p=0,001) também ratifica a utilização da cB frente à cMB, por ser uma medida mais simples. Conclusão: na população estudada, o estado nutricional encontrava-se preservado. assim como a associação da cMB com o iMc/i, a cB demonstrou ser um parâmetro sensível para classificar eutrofia.

Introduction: acute lymphoblastic leukemia (all) is the most common neoplasm in pediatrics, and nutritional assessment is an essential tool for understanding patients' health conditions. The present study aimed to evaluate and describe the nutritional status of pediatric patients newly diagnosed with all and to verify the relation between body mass index for age (BMi-for-age) and other anthropometric measurements. Method: a cross-sectional, observational study was performed with patients from 1 to 18 years of age, newly diagnosed with all, from January 2004 to december 2009. The data collected were age, body weight, height, triceps skinfold (ts), arm circumference (ac) and arm muscle circumference (aMc). The BMi was calculated and the BMi-for-age classification used in the analysis. Pearson's chi-square test and Fisher's exact test were used to analyze the association between anthropometric parameters. Results: 54 patients were included in the study. The classification of "adequate nutritional status" was the most frequent in all anthropometric parameters. in addition, we observed that the association of nutritional status by aMc with BMi-for-age (p=0.001) shows that the BMi-for-age may be adequate for classification of pediatric patients with all at diagnosis. in addition, ac agreement with aMc (p=0.01) of 43% (p=0.001) also confirmed the use of ac versus aMc, as it is a simpler measure. Conclusion: in the studied population the nutritional status was preserved. Just as the association of aMc with BMi-for-age, ac has been shown to be a sensitive parameter for classifying eutrophy
