Efficacy of bi-level erector spinae plane block versus bi-level thoracic paravertebral block for postoperative analgesia in modified radical mastectomy: a prospective randomized comparative study.

Background: Postoperative analgesia in breast surgery is difficult due to the extensive nature of the surgery and the complex innervation of the breast; general anesthesia can be associated with regional anesthesia techniques to control intra- and post-postoperative pain. This randomized comparative study aimed to compare the efficacy of the erector spinae plane block and the thoracic paravertebral block in radical mastectomy procedures with or without axillary emptying.

Methods: This prospective randomized comparative study included 82 adult females who were randomly divided into two groups using a computer-generated random number.

Phase II study of liposomal doxorubicin, docetaxel and trastuzumab in combination with metformin as neoadjuvant therapy for HER2-positive breast cancer.

Background: The aim of this study was to improve activity over single human epidermal growth factor receptor 2 (HER2)-blockade sequential neaodjuvant regimens for HER2-positive breast cancer, by exploiting the concomitant administration of trastuzumab, taxane and anthracycline, while restraining cardiac toxicity with use of liposomal doxorubicin, and by adding metformin, based on preliminary evidence of antitumor activity.

Patients And Methods: This multi-center, single-arm, two-stage phase II trial, assessed the safety and the activity of a new treatment regimen for HER2-positive, early or locally advanced breast cancer. Patients received six 21-day cycles of non-pegylated liposomal doxorubicin, 50 mg/m intravenously (i.

A possible future for anaesthesia in breast surgery: thoracic paravertebral block and awake surgery. A prospective observational study.

Introduction: Quadrantectomy is a surgical procedure traditionally performed under general anaesthesia with intraoperative and postoperative opioid-based analgesia. The use of locoregional anaesthesia techniques in breast surgery has become widespread and allows excellent management of intraoperative and postoperative pain with reduced opioid consumption. We chose thoracic paravertebral block as regional anaesthesia technique in breast surgery to investigate the possibility of carrying out this surgery with the patient awake.

Long-term effects of COVID-19 in a patient on maintenance dialysis.

Coronavirus infectious disease (COVID-19) is a novel respiratory infection highly associated with severe complications in elderly subjects affected by cardiovascular disease. Patients on maintenance dialysis are exceptionally vulnerable because most of them are old and have multiple comorbidities. We report the complex clinical course of SARS-CoV-2 infection in a patient on maintenance dialysis who presented with fever and lung edema.

SARS-CoV-2 infection in dialysis patients in northern Italy: a single-centre experience.

Background: Dialysis patients are considered at high risk for COVID-19 and the infection can easily spread in dialysis units.

Methods: We conducted an observational single-centre cohort study to describe clinical characteristics, treatments and outcomes of dialysis patients with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. We tested patients who presented symptoms or had contact with a confirmed case.

Single shot ultrasound-guided thoracic paravertebral block for opioid-free radical mastectomy: a prospective observational study.

Background: General anesthesia (GA) is the most commonly used anesthesiological technique for radical mastectomy operations and can be associated with loco-regional anesthesia techniques. The aim of our study, carried out on 51 patients, was to assess the effectiveness of thoracic paravertebral block (TPVB) associated with GA, or as a sole anesthesiological technique for postoperative pain control and for the reduction of intra and postoperative opioids consumption.

Materials And Methods: Fifty-one patients with neoplastic breast disease and elected as candidates for radical mastectomy were included in the study.

Gefitinib and afatinib treatment in an advanced non-small cell lung cancer (NSCLC) patient undergoing hemodialysis.

Renal failure in cancer patients is not a rare clinical condition and often contraindicates anticancer drug treatment; moreover, chemotherapeutic drugs are frequently identified as possible iatrogenic cause of renal failure. Molecular therapies, when appropriate, could represent a therapeutic option for cancer patients with severe renal disease, but the lack of knowledge in this field, at present, limits their use in patients undergoing dialysis. Herein we describe a case, at our knowledge the first reported, of a patient with advanced lung adenocarcinoma on maintenance hemodialysis treated with gefitinib and then with afatinib; we also reviewed the literature on epidermal growth factor receptor (EGFR) tyrosine-kinase inhibitors (TKIs) used in NSCLC patients with concomitant renal impairment.

Early initiation of cinacalcet for the treatment of secondary hyperparathyroidism in hemodialysis patients: a three-year clinical experience.

Despite the availability of standard therapy (vitamin D sterols and phosphate binders) for the treatment of secondary hyperparathyroidism (SHPT) in hemodialyzed (HD) patients, a significant percentage of patients still fail to achieve targets recommended by the Kidney Disease Outcomes Quality Initiative (K/DOQI) of the National Kidney Foundation for parathyroid hormone (PTH), calcium, and phosphorus. The calcimimetic cinacalcet (CN) has been shown to be an effective treatment for SHPT, significantly reducing serum PTH while simultaneously lowering calcium, phosphorus, and calcium-phosphorus product levels, thus increasing the proportion of patients achieving the K/DOQI targets for bone mineral parameters. The aim of this study was to evaluate if early treatment with CN had beneficial effects in HD patients with mild-to-moderate SHPT in whom conventional treatments had failed to achieve NKF-K/DOQI targets for PTH, serum-corrected calcium, and phosphorus while minimizing the risk of paradoxical hypercalcemia and/or hyperphosphatemia.

Proteomic analysis of early urinary biomarkers of renal changes in type 2 diabetic patients.

Diabetic nephropathy (DN) is a complication associated with diabetes, leading to end-stage renal disease (ESRD). Despite significant progress in understanding DN, the cellular mechanisms leading to the renal damage are incompletely defined. In this study, with the aim to identify urine biomarkers for the early renal alterations in type 2 diabetes mellitus (T2D), we performed urinary proteomic analysis of 10 normoalbuminuric patients with T2D, 12 patients with type 2 DN (T2DN), and 12 healthy subjects.

A validated model of disease progression in IgA nephropathy.

Background: IgA nephropathy (IgAN) is the most common primary glomerulonephritis in the general population. There is accumulating evidence that immunosuppressive treatment is efficacious in IgAN. However, it is critical to define appropriate indicators for this therapy especially in the wake of potentially deleterious side effects to immunosuppressives.

Activation of coagulation during hemodialysis: effect of blood lines alone and whole extracorporeal circuit.

Activation of coagulation during hemodialysis (HD) is a relevant clinical problem, especially when patients at risk of bleeding are treated. However, little is known about the relative contribution of the various components of the circuit to the thrombotic process. Thus, an experimental model was developed that is aimed at evaluating biochemical markers of coagulation activation at different times and sites throughout the HD circuit.

Comparison between hydroperoxides and malondialdehyde as markers of acute oxidative injury during hemodialysis.

An increased free-radical production has been documented during hemodialysis (HD) particularly when bio-incompatible membranes are utilized. These highly reactive free radicals can cause damage through several pathways, one of the best known being lipid peroxidation. Malondialdehyde (MDA) is a product of lipid peroxidation, which can partly be removed by HD due to its low molecular weight and water solubility.

Changes in conjugated linoleic acid and palmitoleic acid are correlated to retinol levels in chronic renal failure in both hemodialysis and conservative treatment patients.

An increase in conjugated linoleic acid (CLA), a natural fatty acid present in our diet, which possesses anticarcinogenic and antiatherogenic activities in experimental models, has been found in both the plasma and adipose tissue of end-stage chronic renal failure (ESCRF) patients. Increased levels of retinol have also been found in those patients, due to a reduced excretion of the retinol-binding protein. Since retinol is known to influence lipid metabolism, we evaluated whether changes in retinol, CLA, and other fatty acids are correlated in the plasma of CRF patients.

Erythrocyte susceptibility to oxidative stress in chronic renal failure patients under different substitutive treatments.

An increased oxidative stress is now considered one of the major risk factors in chronic renal failure (CRF) patients that may be exacerbated by dialysis. It has been postulated that this increased oxidative stress might cause an augmented red blood cell (RBC) membrane lipid peroxidation with the consequent alteration in membrane deformability. The aim of this study was to evaluate RBC susceptibility to an in vitro induced oxidative stress and RBC antioxidant potential in different groups of CRF patients undergoing different substitutive treatment modalities.

The role of blood volume reduction in the genesis of intradialytic hypotension.

Background: The aim of this multicenter prospective study was to investigate the role of relative blood volume (RBV) reduction on intradialytic hypotension.

Methods: One hundred twenty-three patients on chronic hemodialysis therapy were considered a priori normotensive (reference group A), intradialytic hypotension prone (group B), and hypertensive (group C). RBV was continuously monitored, and diastolic and systolic blood pressure (SBP) and heart rate (HR) were measured at 20-minute intervals during three dialysis sessions.
