To evaluate the use of radioactive iodine-125 seed (RIS) in breast and/or axillary surgery, in patients with breast cancer treated with neoadjuvant chemotherapy (NAC).
Prospective study between January 2016 and June 2020. 80 women T1-3,N0-2,M0 30 RIS marking the breast tumor, 36 both the tumor and the biopsied positive axillary node, and 14 only the axilla. Age 54.7±11.4 years. Tumor size 34.1±14.6mm. Histological type invasive ductal carcinoma 90.0%. Molecular subtypes luminal-A 23.8%, luminal-B/HER2- 33.7%, luminal-B/HER2+ 18.8%, HER2+ 7.5%, basal-like 16,2%.
Of the 66 patients with RIS marking of the tumor (51 pre-NAC, 15 post-NAC), 92.1% had tumor-free surgical margins, with a specimen volume of 126.7±111.2 cm
. Of the 5 second local excisions, in 3 the resection margin was involved (1 mastectomy). Of the 50 patients N1 with RIS marking (MLN), 44 pre-NAC and 6 post-NAC, MLN was identified in 97.2% negative 23, positive 26. In 45/50 patients, sentinel node biopsy (SNB) was performed and it was identified in 93.3% negative 26, positive 16. In 1 case RIS was not placed correctly and SNB was not identified due to non-migration. In 61.9% of the patients, MLN was among the SNB identified in the surgery. In 5 patients with mismatched SNB and MLN, the pathological result of the SNB was negative and the MLN was positive. Axillary lymph node dissection was performed in 53.8% of the patients.
RIS allow to perform breast-conserving surgery and improve detection of residual axillary disease in patients treated with NAC.

To evaluate the migration of
Tc-tilmanocept from the injection site (IS) as well as the uptake in sentinel nodes (SNs) and non-SNs for lymphatic mapping in patients with breast cancer and melanoma, scheduled for SN biopsy after interstitial tracer administration.
For 29 primary tumours in 28 patients (mean age 62y, range 45-81y) scheduled for SN biopsy planar images were acquired 10 and 120 min after administration of 74 MBq
Tc-tilmanocept, in order to evaluate lymphatic drainage as well as uptake ratios between injection site (IS), SN and non-SN. SPECT/CT was performed immediately after delayed planar images to enable anatomical lymph node localization.
SNs were visualized in all patients (100%) with drainage to 34 basins. Uptake in non-SNs was perceived in 16 basins (47%). Number of SNs was concordant between early and delayed images in all basins excepting five (86%). In 24 patients tracer migrated to one lymph node basin (LNB), in three to 2 and in one to 4. When IS was included (n = 29) on imagistent SN visualization frequently accompanied by no or markedly less non-SN uptake. This is associated to rapid migration from the injection site together with increasing SN uptake and retention as expressed by decreasing IS/SN and persistently high SN/non-SN ratios. Further head-to-head comparison of 99mTc-tilmanocept with standard SN radiotracers in larger series of patients is necessary.
Chinese medicine has the potential to modulate allergic rhinitis (AR). There have been studies investigating the treatment efficacy of Yupingfeng San, alone or in combination with other ingredients, in AR, though few have studied the potential mechanisms of these drugs. In the present study, we measured the effects of Jiawei Yupingfeng (JWYPF), a traditional Chinese medicine formula, on mice with ovalbumin-induced AR and explored its underlying mechanism of action.
Forty BALB/c mice were randomly divided into normal control, allergy control and two treatment groups of ten mice each. In the normal control group, mice were sensitized and challenged with saline. The mice in the allergy control and treatment groups were sensitized and challenged with ovalbumin and aluminum hydroxide gel. The treatments of JWYPF and Nasonex were administered intranasally in the AR mice for one week. Several signs of allergic inflammation, such as nasal eosinophils and inflammatory cytokines, were measured to determine the underlying mechanisms.
Mice in the JWYPF and Nasonex groups had significantly lower AR symptom scores than those in the allergy control group (the mean differences between JWYPF and the allergy control, and Nasonex and the allergy control were -2.00±0.35 and -2.40±0.32). After treatment with JWYPF and Nasonex, the levels of ovalbumin-specific IgE and histamine were significantly reduced, as were the levels of interlukin-4 and transforming growth factor-β, while interferon-γ levels were increased (all P<0.0001, vs. allergy control). These two treatments also significantly inhibited eosinophil and mast cell infiltration into the nasal cavity but were not statistically different from one-another.
JWYPF has a potential therapeutic effect on AR via adjusting the rebalance of T helper 1 and T helper 2.

It results from the death of dopaminergic neurons. The pathophysiological mechanisms in idiopathic PD include the production of α-synuclein and mitochondrial respiratory function-affecting complex I, caused by reactive oxygen species. Therefore, the use of natural antioxidants in PD may provide an alternative therapy that prevents oxidative stress and reduces disease progression. In this review, the effects of hydroxytyrosol, Ginkgo biloba, Withania somnifera, curcumin, green tea, and Hypericum perforatum in PD animal and cell line models are compared and discussed. The reviewed antioxidants show evidence of protecting neural cells from oxidative stress in animal and cell models of PD. However, the clinical efficacy of these phytochemicals needs to be optimised and further investigated.
Within the international project May Measurement Month, in Spain, the community pharmacy is where the greatest number of measurements are carried out and where the population can be made aware of the importance of regular blood pressure measurement.
To ascertain the situation of the Spanish population's blood pressure and dissemination of the importance of its regular measurement through the community pharmacies.
Cross-sectional descriptive study carried out in Spanish community pharmacies during the month of May 2018, among pharmacy users of legal age. Systolic blood pressure, diastolic blood pressure and heart rate were measured as main variables.
Five thousand, seven hundred and eighty-five readings were made by 891 pharmacists. One thousand, seven hundred and fifty-five (34.8%) people had not had their blood pressure measured in the last year. Of the participants, 31.2% had high blood pressure readings. Mean systolic blood pressure was 127.1±20.1 and mean diastolic blood pressure 77.5±12.5, higher in men (p<.001). There were normal blood pressure values in 3,981 (68.8%) patients; one high reading in 1,226 (21.2%); and two in 578 (10%). There were 912 (15.76%) patients with SBP≥140 and 314 (5.4%) with DBP≥90. Four (0.07%) hypertensive emergencies were detected.
Three out of ten participants had a high blood pressure reading. Therefore, protocolized blood pressure readings carried out in a health care facility such as the community pharmacy, allowed the identification of a significant number of subjects with high and untreated blood pressure.

The development of human-leukocyte antigen antibodies is a well-known adverse effect of the use of long-term ventricular assist devices (VADs). The aim of this study was to determine the incidence ofsensitization during short-term mechanical circulatory support with VAD (CentriMag), its determinants, and its impact on posttransplant outcomes.
We performed a retrospective review of patients who were bridged to transplant with short-term VAD from 2009 to 2019. Sensitization was defined as a calculated panel-reactive antibody> 10%. The endpoints included overall survival and rejection-free survival.
A total of 89 patients (median age 56.0 [interquartile range, 50.0-59.9] years, 16.8% female) received a short-term VAD as a bridge to transplant. The median duration of support was 23.6 [interquartile range, 16.6-35.0] days. Eleven patients (12.4%) became sensitized during support. The only factor significantly associated with sensitization was female sex (OR, 8.67; 95%CI, 1.93-38.8; P=.005). Of the 89 patients, 21 patients died during support; 68 patients underwent heart transplant. After a mean follow-up of 49.6 ±31.2 months, 8 patients (11.8%) died and 20 (29.4%) had at least 1 rejection episode. https://www.selleckchem.com/products/Rapamycin.html On multivariate analysis, sensitization was an independent predictor of acute rejection (HR, 3.64; 95%CI, 1.42-9.33; P=.007), with a nonstatistically significant trend to higher mortality (HR, 4.07; 95%CI, 0.96-17.3; P=.057).
Sensitization with short-term VADs can occur and is significantly associated with female sex and with rejection. Sensitization also showed a nonstatistically significant trend to higher mortality.

An increased fibrosis of the corpora cavernosa is a prevalent process that underlies most cases of erectile dysfunction. Apelin, an endogenous circulating peptide, has been documented as an important effector on cardiovascular homeostasis, controlling vascular function and reducing fibrosis in multiple pathological conditions. Recently, initial studies have shown that Apelin, acting through the APJ receptor, also modulates penile erection, however, the role of this system on penile structure and intracorporal collagen remodeling has not been investigated yet.
Here we sought to investigate the effect of chronic Apelin treatment on the corpus cavernosum structure of hyperchOlesterolemic mice.
Apolipoprotein gene-deleted (ApoE
) mice were fed with a Western diet for 11 weeks and received Apelin-13 (2 mg/kg/day) or vehicle during the last 3 weeks. Penile samples were obtained for histological and biochemical analyses to assess the intracorporal collagen content and key proteins expression. Furthermore, thes Induced by High-Fat Diet in an MMP-Dependent Mechanism. J Sex Med 2021;18875-888.
These results suggest a local modulation of the Apelin system within the corpus cavernosum. Remarkably, Apelin-13 reduced intracavernosal fibrosis in hypercholesterolemic mice by (i) enhancing MMPs expression and activity; and (ii) inhibiting fibroblast differentiation into myofibroblast. Altogether, these results suggest an essential protective role of Apelin, indicating Apelin/APJ system as a promising candidate for the development of fibrosis-associated erectile dysfunction treatments.
