Intramammary sentinel lymph node with capsular extravasation in breast cancer
Paulo Roberto De Alcantara Fil,Carla Curi,Camila Souza Guatelli,Cynthia Aparecida B. de Toledo,Stephania Martins Bezerra,Fernando Augusto Soares,Fabiana Baroni Makdissi 대한외과학회 2017 Annals of Surgical Treatment and Research(ASRT) Vol.92 No.5
Sentinel lymph node biopsy has been developed as the standard of treatment in breast cancer. Status of axillary sentinel lymph node is known to be a significant prognostic factor. Nevertheless, involvement of an intramammary lymph node with metastasis in breast cancer is a rare radiological and clinical presentation, and with extracapsular extravasation even more uncommon. Historically, reported series of patients with intramammary lymph node diagnosed by final histological examination are small in number and clinical significance of metastasis is still unclear. Here, we report a case of conservative breast cancer surgery with 3 intramammary sentinel lymph nodes containing metastasis and extracapsular extravasation. After multidisciplinary consensus, the patient was surgically reapproached with mastectomy. Even though the 3 intramammary sentinel lymph nodes were positive for metastases, pathology examination did not reveal any signs of malignancy in the mastectomy specimen.

Objective: This study ascertained effects of cactus pear in association with different roughage in the diet of F1 Holstein/Zebu cows on intake, nutrient digestibility, nitrogen balance, ingestive behavior and performance. Methods: Eight cows with 72±11 days of lactation were used. The experimental design was simultaneous in two 4×4 Latin squares. Four experimental diets were used: Diet 1, sorghum silage as exclusive roughage; Diet 2, sorghum silage associated with cactus pear in a proportion of 50% of the roughage (dry matter basis); Diet 3, elephant grass (Pennisetum purpureum cv. Roxo) as exclusive roughage; Diet 4, elephant grass associated with cactus pear in a proportion of 50% of the roughage. The roughage:concentrate ratio was 75:25. Results: Dry matter intake (p = 0.01) was higher with sorghum silage. There were differences in dry matter intake (p = 0.01), crude protein (p<0.01), ether extract (p = 0.01), non-fibrous carbohydrates (p<0.01) and total digestible nutrients (p = 0.01) among the diets. Cactus pear in the diet reduced water intake by 44.52% (p<0.01). The nitrogen balance was 59.71% and 27.49% lower in animals treated with exclusive sorghum silage and sorghum silage associated with cactus pear in relation to diets with elephant grass and elephant grass associated with cactus pear, respectively (p<0.01). The diets did not influence the milk production (p = 0.70), 3.5% fat corrected milk production (p = 0.72) or feed efficiency (p = 0.61). Conclusion: The association of cactus pear with sorghum or elephant grass silage does not alter milk production, reduces the intake of dry matter and water and improves the digestibility of nutrients.

This study evaluated to determine the phenolic and flavonoids contents, and antioxidant, anti-inflammatory, and antiproliferative activity of the hydromethanolic extracts of the leaves, pulp, and seeds of Annona cacans. The isolation and structural identification of the constituent acetogenin, phenolic acid, and flavonoids were also reported. Antioxidant capacity was determined by the 2,2-diphenyl-1-picrylhydrazyl (DPPH), ethylbenzothiazoline-6-sulfonic acid (ABTS), and β-carotene/linoleic acid methods. Cell proliferation was determined by spectrophotometric quantification of the cellular protein content using a sulforhodamine B assay. Anti-inflammatory activity was evaluated in paw edema model, to myeloperoxidase (MPO) activity induced by carrageenan in mice. Fractionation resulted in the isolation of one acetogenin (annoreticuin-9-one), two flavonoids (quercetin-3-O-β-glucoside-6-O-α-rhamnoside and kaempferol-3-O-β-glucoside), and one phenolic acid (p-coumaric acid). The pulp extract presented potent antioxidant activities by the DPPH (IC50 = 44.08 μg/mL) and ABTS (IC50 = 39.32 μg/mL) methods, as well as high contents of phenols (618.95 mg GA/g) and flavonoids (477.35 mg QE/g). The bioguided fractionation demonstrated that the ethyl acetate fraction of the pulp extract and annoreticuin-9-one showed potent antiproliferative activity against ovarian cancer (GI50 = 6.4 μg/mL). The anti-inflammatory activity demonstrated significant inhibition of edema compared to the control group in 2 and 4 h; in addition, the extracts inhibited the increase in MPO activity after 6 h, when compared to the DEX and control groups. For the first time, this study demonstrated antioxidant, anti-inflammatory, and antiproliferative activity, as well as compounds isolated, suggesting that A. cacans could also be potential sources for prevention of cancer and other diseases associated with oxidative stress.

Background: Nonadherence to antihypertensive treatment is one of the main causes of the lack of blood pressure (BP) control. The coronavirus disease (COVID-19) pandemic imposes substantial social restriction impairing the medical care routine, which may influence adherence to the antihypertensive treatment. To assess the rate of nonadherence to antihypertensive drug treatment during the COVID-19 pandemic. Methods: This is a cross-sectional study evaluating hypertensive adult patients from a tertiary outpatient clinic. From March to August 2020, patients were interviewed by telephone during the social distancing period of the COVID-19 pandemic. We evaluated biosocial data, habits, attitudes, and treatment adherence using the 4-item Morisky Green Levine Scale during the social distancing. Uncontrolled BP was defined by BP ≥ 140/90 mmHg. Clinical and prescription variables for drug treatment were obtained from the electronic medical record. We performed a multivariate analysis to determine the predictors of nonadherence to BP treatment. Results: We studied 281 patients (age 66 ± 14 years, 60.5% white, 62.3% women, mean education of 9.0 ± 4 years of study). We found that 41.3% of the individuals reported poor adherence to antihypertensive drug treatment and 48.4% had uncontrolled BP. Subsample data identified that adherence was worse during the pandemic than in the previous period. The variables that were independently associated with the nonadherence during the pandemic period were black skin color (odds ratio [OR], 2.62; 95% confidence interval [CI], 1.46–4.68), and intermittent lack of access to antihypertensive medication during the pandemic (OR, 2.56; 95% CI, 1.11–5.89). Conclusions: Beyond traditional variables associated with poor adherence, the lack of availability of antihypertensive medications during the study underscore the potential role of pandemic on hypertension burden.
