Changes in body composition in early breast cancer patients treated with aromatase inhibitors.

PURPOSE: The aim of the study was to analyze the modification of total and regional body composition in early breast cancer patients treated with aromatase inhibitors (AIs). METHODS: This is a prospective, single-center, observational, longitudinal study. Four-hundred and twenty-eight patients treated with adjuvant aromatase inhibitors were enrolled at the Medical Oncology and Breast Unit of Spedali Civili Hospital in Brescia from September 2014 to June 2022. Several body composition parameters including total and regional fat and lean body mass were investigated with dual-energy X-ray absorptiometry (DXA) scan at baseline and after 18 months of treatment with aromatase inhibitors. RESULTS: A significant increase in fat body mass (mean + 7.2%, 95% confidence interval [CI]: 5.5;8.9%) and a reduction in lean body mass (mean -3.1%, 95% CI -3.9; -2.4) were documented in this population. The changes in fat and lean body mass varied considerably according to different body districts ranging between + 3.2% to + 10.9% and from-1.3% to -3.9%, respectively. CONCLUSION: Aromatase inhibitor adjuvant therapy in early breast cancer is associated with changes in body composition, with a wide variability among different body districts, leading to a risk of sarcopenic obesity. Supervised physical exercise that focuses on single body parts that may display detrimental variations may be beneficial for AIs treated patients.

Immune-related adverse events as potential surrogates of immune checkpoint inhibitors' efficacy: a systematic review and meta-analysis of randomized studies.

BACKGROUND: Immune-related adverse events (irAEs) are frequently reported during immune checkpoint inhibitor (ICI) therapy and are associated with long-term outcomes. It is unknown if the irAE occurrence is a valid surrogate of ICIs' efficacy. METHODS: We identified articles reporting the results of randomized trials of experimental ICI therapy in solid tumors with a systematic search. The control arms could be placebo, cytotoxic/targeted therapy, or ICI therapy. We extracted the hazard ratios for overall survival (OS) with the number of OS events per arm and the number and percentages of overall and specific irAEs of grade 1-2 and grade 3-4 per arm. We estimated the treatment effect on the potential surrogate outcome with the odds ratio of the irAE rate between the experimental and the control arm. The statistical analysis consisted of weighted linear regression on a logarithmic scale between treatment effects on irAE rate and treatment effects on OS. RESULTS: Sixty-two randomized trials were included for a total of 79 contrasts and 42 247 patients. The analyses found no significant association between the treatment effects for overall grade 1-2 or grade 3-4 irAE rates or specific (skin, gastrointestinal, endocrine) irAE rates. In the non-small-cell lung cancer (NSCLC) trial subset, we observed a negative association between treatment effects on overall grade 1-2 irAEs and treatment effects on OS in studies with patients selected for programmed death-ligand 1 expression (R2 = 0.55; 95% confidence interval 0.20-0.95; R = -0.69). In the melanoma trial subset, a negative association was shown between treatment effects on gastrointestinal grade 3-4 irAEs and treatment effects on OS in trials without an ICI-based control arm (R2 = 0.77; 95% confidence interval 0.24-0.99; R = -0.89). CONCLUSIONS: We found low-strength correlations between the ICI therapy effects on overall or specific irAE rates and the treatment effects on OS in several cancer types.

[Bilio-intestinal bypass in the treatment of metabolic syndrome in obese patient]. / Il by-pass bilio-intestinale nel trattamento della sindrome metabolica nel paziente obeso.

INTRODUCTION: obesity (O) is a chronic patologic condition, evolutive and relapsing, with multifactorial etiopathogenesis, consisting in an alteration of the body's composition characterized by a relative and absolute excess of fat, that gets worse the life quality and causes complications that can lead to death. PATIENTS AND METHODS: experience concerns twenty-five diabetic obese patients underwent bilio-intestinal by-pass between January 2006-December 2007. All these patients, before the surgical operation, underwent a rigorous clinical and laboratory examination. Besides, a precise rate control of laboratory, overlap with those performed in the pre-operative period of operation, was required for each patient: the first after one month, the second after six months and the third after twelve months. RESULTS: the average weight loss was about 40 kg and, more important, these data show that the BMI is reduced, until to become stable, after 12 months from surgical operation, about values 34-31 Kg/m², obtaining, in this way, an improvement of values in the development metabolic syndrome and, above all, heart rate and ventricular repolarization. CONCLUSIONS: the data obtained by our study support the hypothesis to suggest the operations of bariatric malassorbing surgery, in particular bilio-intestinal by-pass, as prophylactic methods for dismetabolics diseases, with reduction of cardiovascular risk in obese patient.

Pemetrexed in combination with oxaliplatin as a first-line therapy for advanced gastric cancer: a multi-institutional phase II study.

BACKGROUND: This clinical trial assessed the efficacy of pemetrexed combined with oxaliplatin (PEMOX) in patients with advanced gastric cancer (AGC). PATIENTS AND METHODS: Forty-four patients with untreated AGC were enrolled to evaluate response rate (RR). Patients received pemetrexed (500 mg/m(2)) with vitamin supplementation and oxaliplatin (120 mg/m(2)) every 21 days for six cycles or until disease progression occurred. RESULTS: Median age was 62 years (range 26-76). The majority of patients (93%) had metastatic disease. Sixteen of the 44 patients achieved confirmed response [RR 36%; 95% confidence interval (CI) 22% to 52%]; four complete responses and 12 partial responses (complete and partial responses according to the RECIST guidelines are the confirmed-responses observed in the study population). Median time to tumor progression (TTP) was 6.2 months (95% CI 4.3-7.5) and median survival was 10.8 months (95% CI 7.7-17.2). A total of 220 cycles were administered, with a median of six cycles. Most common grade 3/4 toxic effects were neutropenia in 41% of patients (19% of cycles) and thrombocytopenia in 11% of patients (4% of cycles). Treatment delays or dose reductions for toxicity occurred in 10% and 5% of cycles, respectively. CONCLUSIONS: PEMOX is active and well tolerated in AGC. RR, TTP, and survival were comparable to those achieved in studies using different 5-fluorouracil (5-FU)-oxaliplatin combinations, without the inconvenience of prolonged 5-FU schedules.

Case report: laparoscopic cholecystectomy in situs viscerum inversus.

Situs viscerum inversus is a rare condition, in which the organs are transposed from their normal location in the opposite side of the body. The inversion of L-R asymmetry may be complete (SVI totalis) or partial (SVI partialis), whereby transposition is confined to either the abdominal or thoracic viscera. The authors report a case of videolaparocholecystectomy for cholelithiasis successfully performed on a 41-year-old Caucasian woman with situs viscerum inversus totalis. The patient was discharged on the 2nd postoperative day. The symptomatology disappeared right after the intervention, and still now, after a follow-up of six months, is absent. The procedure was safely performed on the patient with no particular difficulties, except for the reverse position of the angle between the operating and exposing trocars, which led to a difficult approach to the Calot triangle when using the right hand of the surgeon.

BCL-2 immunohistochemical evaluation in B-cell chronic lymphocytic leukemia and hairy cell leukemia before treatment with fludarabine and 2-chloro-deoxy-adenosine.

Bcl-2 overexpression has been shown to be associated with several malignancies, including B-cell chronic lymphocytic leukemia (CLL) and non-Hodgkin's lymphomas (NHL), mainly low-grade and follicular in type. It has as yet not been described in hairy cell leukemia (HCL). In 30 patients with CLL and 14 with HCL who were consecutively selected for treatment with purine analogues (Fludarabine in CLL and 2-chloro-deoxy-adenosine in HCL), we evaluated bcl-2 oncoprotein expression in leukemic cells on marrow sections that were taken before treatment and stained immunohistochemically with a monoclonal antibody (Dakopatts 124 clone), by the avidin-biotin-peroxidase method. All samples were found to be bcl-2 positive, with a staining intensity that was moderate to strong in CLL and weak to moderate in HCL. 83% of CLL and 100% of HCL patients were responsive to purine analogues. These findings show that bcl-2 is overexpressed in almost all cases CLL and HCL and that bcl-2 overexpression does not predict a poor response to purine analogues, which are believed to induce apoptosis.

Fine-needle aspiration cytology of the breast: a preliminary report on telepathology through Internet multimedia electronic mail.

Telepathology is a field of telemedicine that enables the exchange of histologic and cytologic images for consultations among pathologists of two or more remote institutions, through a suitable communication channel. The Internet can connect several scientific and medical institutions because of the existence of a set of standard protocols that allow different computers to communicate; multimedia electronic mail is one such protocol, which allows asynchronous transmission of multimedia documents, i.e., including text, images, movies, and sounds. The aim of the present article is to test a novel approach in which Internet multimedia electronic mail is used as a communication medium to obtain an asynchronous telepathology tool for remote consultation. To assess the diagnostic validity of the method, 48 cases of fine-needle aspiration cytology of breast lesions were sent from Udine to Trento, Italy. Comparisons between local and remote diagnoses, and cytologic diagnoses versus subsequent histologic reports demonstrated that Internet multimedia electronic mail is suitable for remote consultation. Internet multimedia electronic mail thus presents an additional diagnostic tool that is easy to use, available on a wide range of computers, and inexpensive, because its cost is independent of distance.

Air handling units for hospitals.

Air handling units should provide proper quality and conditioned air to various hospital areas. Unit capacity should be able to meet limited space functionality or load changes as well as any smoke control requirements. System components should be readily accessible and appropriate for spaces served. In summary, engineers should consider the following: Environmental design criteria for area being served Components desired Unit type required Economic issues affecting design. Using this approach, design engineers can design hospital air handling units methodically and logically.
