Combination of Supramicrosurgical Lymphatico-Venular Anastomosis (sLVA) and Lymph-Sparing Liposuction in Treating Cancer-Related Lymphedema: Rationale for a Regional One-Stage Approach.

Objective: Cancer-related lymphedema represents a potential complication of cancer treatment. The aim of this study is to evaluate the effectiveness of the combination of lymphatico-venular anastomosis and liposuction in the treatment of secondary lymphedema. Methods: We present a retrospective analysis of patients affected by cancer-related unilateral limb lymphedema. Inclusion criteria included previous neoplastic pathology with the consequent development of unilateral limb lymphedema, while the exclusion criteria included the presence of comorbidities and the persistence of cancer, as well as previous lymphatic surgery. The outcomes to be included were a reduction in the limb volume and lymphangitis rate, and an improvement in the quality of life. Patients' data were assessed before surgery and 1 year after surgery. Perioperative management included clinical and ultrasonographical evaluations. Under local anesthesia, lymphatico-venular anastomosis with the supramicrosurgical technique and the liposuction of the affected limb was performed in the same surgical session. Results: A total of 24 patients were enrolled in the study. One year after the surgery, an average volume reduction of 37.9% was registered (p = 0.0000000596). The lymphangitis rate decreased after surgery from 4.67 to 0.95 per year (p = 0.000007899). The quality-of-life score improved from 68.7 to 16 according to the LLIS scale. Conclusions: The combination of LVA and liposuction represents a valid strategy for treating cancer-related lymphedema, ensuring stable results over time. In addition, it can be performed under local anesthesia, resulting in being minimally invasive and well-tolerated by patients. This paper reports on the short-term efficacy of this combined technique.

Evaluation of age-specific causes of death in the context of the Italian longevity transition.

In many low-mortality countries, life expectancy at birth increased steadily over the last century. In particular, both Italian females and males benefited from faster improvements in mortality compared to other high-income countries, especially from the 1960s, leading to an exceptional increase in life expectancy. However, Italy has not become the leader in longevity. Here, we investigate life expectancy trends in Italy during the period 1960-2015 for both sexes. Additionally, we contribute to the existing literature by complementing life expectancy with an indicator of dispersion in ages at death, also known as lifespan inequality. Lifespan inequality underlies heterogeneity over age in populating health improvements and is a marker of uncertainty in the timing of death. We further quantify the contributions of different age groups and causes of death to recent trends in life expectancy and lifespan inequality. Our findings highlight the contributions of cardiovascular diseases and neoplasms to the recent increase in life expectancy but not necessarily to the decrease in lifespan inequality. Our results also uncover a more recent challenge across Italy: worsening mortality from infectious diseases and mortality at older age.

Causes-of-Death Specific Estimates from Synthetic Health Measure: A Methodological Framework.

Life expectancy at birth has attracted interest in various fields, as a health indicator that measures the quality of life. Its appeal relies on the ability to enclose and summarize all the factors affecting longevity. However, more granular information, provided by social indicators such as cause-of-death mortality rates, plays a crucial role in defining appropriate policies for governments to achieve well-being and sustainability goals. Unfortunately, their availability is not always guaranteed. Exploiting the relationship between life expectancy at birth and cause-of-death mortality rates, in this paper we propose an indirect model to produce estimates of death rates due to specific causes using the summary indicator of life expectancy at birth, thus the general levels of the observed mortality. By leveraging on a constrained optimization procedure, we ensure a robust framework where the cause-specific mortality rates are coherent to the aggregate mortality. The main advantage is that indirect estimations allow us to overcome the data availability problem: very often the cause-specific mortality data are incomplete, whereas data on the aggregate mortality are not. Using data from the Human Cause-of-Death Database, we show a numerical application of our model to two different countries, Russia and Spain, which have experienced a different evolution of life expectancy and different leading causes of death. In Spain, we detected the impact of several public health policies on the lowered levels of cancer deaths and related life expectancy increases. As regards the Russia, our results catch the effects of the anti-alcohol campaign of 1985-1988 on longevity changes.

Covid-19 pandemic: the impact of Italian lockdown on maxillofacial trauma incidence in southern Tuscany.

The outbreak of the Covid-19 pandemic has seriously affected our society. Governments have difficult situations by adopting strict and severe mitigation measures in order to contain the pandemic spreading. These decisions influenced significatively people's behavior changing their habits and routines. This study offers a statistical analysis of the incidence of the Maxillo-Facial traumas in Tuscany southern area, during the pandemic lockdown. The statistical analyzed has been obtained comparing the maxillo-facial trauma occurrence during the Italian lockdown between the 9th of March and the 18th of May 2020 in comparison with same period of the five previous years. KEY WORDS: Covid-19, Italian covid-19, Maxillofacial surgery, Maxillofacial trauma, Pandemic, Surgery management, Trauma incidence in Italy.

Gastric Cancer Maximum Tumour Diameter Reduction Rate at CT Examination as a Radiological Index for Predicting Histopathological Regression after Neoadjuvant Treatment: A Multicentre GIRCG Study.

AIM: To investigate the role of maximum tumour diameter (D-max) reduction rate at CT examination in predicting histopathological tumour regression grade (TRG according to the Becker grade), after neoadjuvant chemotherapy (NAC), in patients with resectable advanced gastric cancer (AGC). MATERIALS AND METHODS: Eighty-six patients (53 M, mean age 62.1 years) with resectable AGC (≥T3 or N+), treated with NAC and radical surgery, were enrolled from 5 centres of the Italian Research Group for Gastric Cancer (GIRCG). Staging and restaging CT and histological results were retrospectively reviewed. CT examinations were contrast enhanced, and the stomach was previously distended. The D-max was measured using 2D software and compared with Becker TRG. Statistical data were obtained using "R" software. RESULTS: The interobserver agreement was good/very good. Becker TRG was predicted by CT with a sensitivity and specificity, respectively, of 97.3% and 90.9% for Becker 1 (D-max reduction rate > 65.1%), 76.4% and 80% for Becker 3 (D-max reduction rate < 29.9%), and 70.8% and 83.9% for Becker 2. Correlation between radiological and histological D-max measurements was strongly confirmed by the correlation index (c.i.= 0.829). CONCLUSIONS: D-max reduction rate in AGC patients may be helpful as a simple and reproducible radiological index in predicting TRG after NAC.

High-resolution MR lymphangiography for planning lymphaticovenous anastomosis treatment: a single-centre experience.

PURPOSE: This article illustrates the feasibility of MR lymphangiography (MRL) for imaging lymphatic vessels in patients with lymphedema, its accuracy in distinguishing lymphatic vessels from veins, and its utility for planning Lymphaticovenous anastomosis (LVA) treatment. MATERIALS AND METHODS: We prospectively enrolled 30 patients (24 women, range 18-70, 17 cases of lower limb lymphedema, 6 cases of primary lymphedema). All the patients underwent MRL, using a 1.5T MR unit (Signa Twin Speed Hdxt; GE), after the subcutaneous injection of gadobenate dimeglumine (Gd-BOPTA) with a little dose of lidocaine into the interdigital webs of the dorsal foot or hand. Lymphatic vessels identified for the LVA at MRL were histologically confirmed after surgery. Enhancement of lymphatic vessels and veins at different times after injection of contrast medium and their diameters were measured. RESULTS: A total of 79 lymphatic vessels were clearly identified in 29 patients at MRL; their morphology was tortuous in 22 patients and rectilinear in 7, whereas, the adjacent veins were straight with focal bulging only at the level of venous valve; the enhancement kinetic of the two different structures were different (p < 0.05) but the mean diameter of affected lymphatic vessels was similar to the adjacent veins (p > 0.05). Thirty-four out of 38 specimens of presumed lymphatic vessels at MRL, collected during surgery, resulted positive at the immunoistochemical marker d2-40, with a significant association (Chi-square = 40.421, DF = 1, p < 0.05, contingency coefficent 0.644). One patient had an early complication 1 month after treatment. CONCLUSIONS: MRL is easy and safe to use and combines extensive information on the anatomy and functionality of lymphatic vessels and veins in a single process; therefore, it could be useful in LVA treatment planning and evaluating possible super-microsurgical treatment complications in patients with lymphedema.
