Posteriormente, se realizó la discusión, en la cual se ha podido conocer que muchas empresas se preocupan por brindar una adecuada gestión de calidad de los servicios. Finalmente, se concluyó que la calidad de los servicios es de gran beneficio para las diferentes empresas; ya que, le permite obtener ganancias, mantener a sus clientes fidelizados y satisfechos. Por ello, no deben verlo como un gasto sino como una inversión ya que les ayudará a poder mantenerse en el tiempo, le permitirá obtener beneficios rentabilidad y ser competitivas en el mercado ante otras entidades del mismo rubro

The Effect of Adjuvant Radiotherapy on One- and Two-Stage Prosthetic Breast Reconstruction and on Autologous Reconstruction: A Multicenter Italian Study among 18 Senonetwork Breast Centres

Purpose: In modern breast cancer treatment, a growing role has been observed for breast reconstruction together with an increase in clinical indications for postmastectomy radiotherapy (PMRT). Choosing the optimum type of reconstructive technique is a clinical challenge. We therefore conducted a national multicenter study to analyze the impact of PMRT on breast reconstruction. Methods: We conducted a retrospective case-control multicenter study on women undergoing breast reconstruction. Data were collected from 18 Italian Breast Centres and stored in a cumulative database which included the following: autologous reconstruction, direct-to-implant (DTI), and tissue expander/immediate (TE/I). For all patients, we described complications and surgical endpoints to complications such as reconstruction failure, explant, change in type of reconstruction, and reintervention. Results: From 2001 to April 2020, 3116 patients were evaluated. The risk for any complication was significantly increased in patients receiving PMRT (aOR, 1.73; 95% CI, 1.33-2.24; p < 0.001). PMRT was associated with a significant increase in the risk of capsular contracture in the DTI and TE/I groups (aOR, 2.24; 95% CI, 1.57-3.20; p < 0.001). Comparing type of procedures, the risk of failure (aOR, 1.82; 95% CI, 1.06-3.12, p=0.030), explant (aOR, 3.34; 95% CI, 3.85-7.83, p < 0.001), and severe complications (aOR, 2.54; 95% CI, 1.88-3.43, p < 0.001) were significantly higher in the group undergoing DTI reconstruction as compared to TE/I reconstruction. Conclusion: Our study confirms that autologous reconstruction is the procedure least impacted by PMRT, while DTI appears to be the most impacted by PMRT, when compared with TE/I which shows a lower rate of explant and reconstruction failure. The trial is registered with NCT04783818, and the date of registration is 1 March, 2021, retrospectively registered

Secondary Membranous Nephropathy Due to Benign Tumors in 2 Young Women: A Case Report

Membranous nephropathy (MN) is one of the most common causes of adult-onset nephrotic syndrome. We describe the cases of 2 young women in their 20s presenting with nephrotic syndrome due to antiphospholipase A2 receptor (anti-PLA2R)\u2013negative MN, that was found to be associated with benign tumors. Both women had no extrarenal symptoms of a connective tissue disease, infection, or malignancy. They both had been previously healthy and were not receiving treatment with any drugs. Both had MN on kidney biopsy. Biopsies were negative for PLA2R antigen, and their serum did not demonstrate the presence of anti-PLA2R antibodies. Both were investigated for a secondary cause on the basis of negative anti-PLA2R serology and biopsy features supportive of secondary MN and were found to have benign tumors on radioimaging: a uterine leiomyoma and mesenteric fibromatosis, respectively. In both instances, the nephrotic syndrome remitted following resection of the tumors. To our knowledge, uterine leiomyoma and mesenteric fibromatosis have not previously been described in association with MN. These cases highlight the importance of pursuing a secondary cause of MN in patients without anti- PLA2R antibodies in serum or PLA2R antigen on kidney biopsy

Early interstitial macrophage infiltration with mild dysfunction is associated with subsequent kidney graft loss

Macrophage infiltration is associated with unfavorable kidney graft outcome in protocol biopsies, but few studies have evaluated its impact on clinical practice. We therefore prospectively evaluated 37 kidney transplant recipients (KTRs) who underwent kidney biopsy due to slight increases in serum creatinine, or mild proteinuria (&gt;0.3&nbsp;g/24&nbsp;hr), in the first post-transplant year. Banff score, CD68+count (score 0-3) by immunohistochemistry, and 1-year DSA were assessed. DGF was reported in 10 (27%) patients, 6 (16%) had normal biopsy, 7 (19%) borderline lesions, 13 (35%) IFTA, and 11 (30%) other lesions. Fifteen KTRs had grade 3 CD68+ infiltration, and 47% developed de novo DSA. During a 6.2&nbsp;\ub1&nbsp;2.7&nbsp;year follow-up, four patients (11%) suffered from biopsy-proven T-cell rejection, 17 KTRs (46%) lost their graft (12 in the grade 3 CD68+group). Graft survival was lower in KTRs with grade 3 CD68+ infiltration (P&nbsp;=&nbsp;0.0074; log-rank test). Grade 3 CD68+ infiltrate was an independent predictor of graft loss (HR 5.41, 95% CI 1.74-16.8; P&nbsp;=&nbsp;0.003), together with more severe graft dysfunction at biopsy (HR 6.41, 95% CI 2.57-16; P&nbsp;&lt;&nbsp;0.001). We conclude that grade 3 CD68+interstitial infiltration is associated with increased risk of subsequent graft loss independent of other factors

The Evolving Scenario of COVID-19 in Hemodialysis Patients

Coronavirus disease 2019 (COVID-19) is a rapidly changing disease. Therefore, in this study, to evaluate the evolution of COVID-19 in hemodialysis patients, we retrospectively compared patients affected by COVID-19 during the first pandemic waves of 2020 (from March to December 2020-Group 1) with patients with COVID-19 from September 2021 to February 2022 (Group 2) after the full completion of vaccination. Group 1 was constituted of 44 patients (69.3 ± 14.6 years), and Group 2 of 55 patients (67.4 ± 15.3 years). Among Group 2, 52 patients (95%) were vaccinated. Patients of Group 2, compared with Group 1, were more often asymptomatic (38 vs. 10%, p = 0.002) and reported less frequent fever and pulmonary involvement. At diagnosis, Group 2 showed a significantly higher number of lymphocytes and lower levels of circulating IL-6 (16 ± 13.3 vs. 41 ± 39.4 pg/mL, p = 0.002). Moreover, in Group 2, inflammatory parameters significantly improved after a few days from diagnosis. Patients of Group 2 presented a lower hospitalization rate (12.7 vs. 38%, p = 0.004), illness duration (18.8 ± 7.7 vs. 29.2 ± 19.5 days, p = 0.005), and mortality rate (5.4 vs. 25%, p = 0.008). Finally, responders to the vaccination (80% of vaccinated patients) compared with nonresponders showed a reduction in infection duration and hospitalization (5 vs. 40%, p = 0.018). In conclusion, we found that COVID-19 presentation and course in hemodialysis patients have improved over time after the implementation of vaccine campaigns. However, due to the evolving nature of the disease, active surveillance is necessary
