Physical concepts based on the Clausius-Clapeyron relation and on the thermodynamics and aerosol characteristics associated with updrafts, global climate models assuming different parametrizations and lightning-related output variables, and lightning-related data (thunderstorm days) are being used to infer the lightning incidence in a warmer planet, motivated by the global warming observed. In all cases, there are many gaps to be overcome making the lightning response to the global temperature increase still unpredicted. Values from almost 0% (no increase) to 100% have been estimated, being 10% the most common value. While the physical concepts address only part of the problem and the global climate models need to make many simple assumptions, lightning-relate data have strong time and space limitations. In this context, any new evidence should be considered as an important contribution to better understand how will be the lightning incidence in the future. In this article, we described new results about the occurrence of thunderstorms from 1850 to 2010 (a period of 160 years) in the city of Rio de Janeiro, in the Southeast of Brazil. During this period thunderstorm days were recorded in the same location, making this time series one of the longest series of this type available worldwide. The data support an increase of 21% in the mean annual thunderstorm days during the period, while surface temperature increased by 0.6ckground-color:#ffffff;font-style:normal;text-indent:0px;display:inline !important;font-family:Verdana;white-space:normal;orphans:2;flo

Diabetic foot syndrome:Immune-inflammatory features as possible cardiovascular markers in diabetes

引用

World Journal of Orthopedics 2015年第1期6卷 62-76页

作者： Antonino Tuttolomondo carlo Maida Antonio pinto Dipartimento Biomedico di Medicina Interna e Specialistica U.O.C di Medicina Interna e CardioangiologiaUniversità degli Studi di Palermo

Diabetic foot ulcerations have been extensively reported as vascular complications of diabetes mellitus associated with a high degree of morbidity and mortality. Diabetic foot syndrome(DFS), as defined by the World Health Organization, is an "ulceration of the foot(distally from the ankle and including the ankle) associated with neuropathy and different grades of ischemia and infection". Pathogenic events able to cause diabetic foot ulcers are *** the commonest causes of this pathogenic pathway it's possible to consider peripheral neuropathy, foot deformity, abnormal foot pressures, abnormal joint mobility, trauma, peripheral artery disease. Several studies reported how diabetic patients show a higher mortality rate compared to patients without diabetes and in particular these studies under filled how cardiovascular mortality and morbidity is 2-4 times higher among patients affected by type 2 diabetes mellitus. This higher degree of cardiovascular morbidity has been explained as due to the observed higher prevalence of major cardiovascular risk factor, of asymptomatic findings of cardiovascular diseases, and of prevalence and incidence of cardiovascular and cerebrovascular events in diabetic patients with foot complications. In diabetes a fundamental pathogenic pathway of most of vascular complications has been reported as linked to a complex interplay of inflammatory, metabolic and procoagulant variables. These pathogenetic aspects have a direct interplay with an insulin resistance, subsequent obesity, diabetes, hypertension, prothrombotic state and blood lipid disorder. Involvement of inflammatory markers such as IL-6 plasma levels and resistin in diabetic subjects as reported by Tuttolomondo et al confirmed the pathogenetic issue of the a "adipo-vascular" axis that may contribute to cardiovascular risk in patients with type 2 diabetes. This "adipo-vascular axis" in patients with type 2 diabetes has been reported as characterized by lower plasma l

为比较不同气缸盖材料在实际循环热负荷条件下的疲劳特性,开发了1套用于进行热疲劳分析的新型试样设计与试验系统。采用有限元分析对试样几何结构和热循环进行了优化。利用高频感应加热器对热疲劳试样的哑铃形截面进行了局部加热,并利用压缩空气对其进行了冷却。然后,利用试样范围内产生的非均匀热梯度内部诱导产生机械应变,从而精确模拟气缸盖内气阀桥在实际工况下的运行情况。所得到的疲劳寿命不仅与合金固有的抗疲劳强度有关,而且还与导热系数、弹性模量和热膨胀系数等其他相关属性有关。该试验是比较不同合金热疲劳应用的必要工具。为了研究组成变化及热处理对热机性能的影响,对4种铝合金进行了测试,并对该试验方法及其结果进行了详细介绍。

The extraction of the physical parameters of long period gratings from the spectral response is not an easy process. We present a demodulation technique to synthesize the physical parameters of a long period grating recorded in an optical fibre. The demodulation is achieved through the implementation of a genetic algorithm. The extracted parameters are in agreement with the typical values known for long period gratings.

A New Device for Intermittent Emptying of the Bladder in children and Adults: A Long-Term Follow-Up

引用

Open Journal of Urology 2023年第6期13卷 161-172页

作者： Salvador V. c. Lima Fernanda c. F. S. calisto Flavia c. M. pinto Daniel c. c. Aragão Eugênio S. Lustosa Heron O. Schots Paulo A. A. Alves Fábio O. Vilar Department of Surgery Center for Health Sciences Federal University of Pernambuco Recife Brazil Department of Urology Federal University of Pernambuco Recife Brazil

contextualization: Emptying the bladder is a challenging problem for the urological community. Intermittent catheterization is the most widely used method to restore bladder emptying mechanism. However, this procedure can have a negative impact on self-image and result in a decline in the quality of life of patients. In this context, the use of a bladder emptying device (SVcATH3D) proposes to be effective and have a positive impact on the quality of life of different patients. Objective: The objective of the study was to evaluate the functionality of a new device for both intermittent and controlled emptying of the bladder in both sexes and ages. Materials and methods: A randomized clinical trial was conducted with 251 patients, with different bladder problems, from March 2013 to January 2023. After randomization, the patients were divided into two groups: Group I (SVcATH3D) and Group II (clean Intermittent catheterization). The primary outcome was defined as the impact on quality of life. Data on episodes of urinary tract infection, adverse effects, number of diaper use and treatment costs were analyzed. Results: The apposition of the SVcATH3D was performed on an outpatient basis, with no complications during the procedures. The patients were followed up for 10 years. There was a significant improvement in quality of life when comparing the moments before and after the use of SVcATH3D (p conclusion: The study using SVcATH3D showed promising results in relation to functionality, showing improvement in quality of life with a reduction in episodes of urinary infection and amount of diapers/day. This allows us to conclude that SVcATH3D can represent an important step in the treatment of patients suffering from various bladder problems both incontinence and affecting emptying mechanism.

Impact of jejunostomy during esophagectomy for cancer on health related quality of life

引用

chinese Journal of cancer Research 2014年第6期26卷 678-684页

作者： Marco Scarpa Francesco cavallin Giulia Noaro Eleonora pinto Rita Alfieri Matteo cagol carlo castoro Surgical Oncology Unit Veneto Institute of Oncology (IOV-IRCCS) Padua 35128 Italy

Background： The aim of this study was to evaluate the impact of jejunostomy during esophagectomy for cancer on postoperative health-related quality of life（HRQL）.Methods： We evaluate all consecutive patients who underwent esophagectomy for cancer at the surgical oncology unit of the Veneto Institute of Oncology（IOV-IRccS） between January 2008 and March 2014. The primary outcome was HRQL, which was assessed using nine scales of EORTc c30 and OES18 questionnaires. General linear models were estimated to evaluate mean score difference（MD） of each selected scale in patients with and without jejunostomy, adjusting for clinically relevant confounders. The secondary outcomes were morbidity, hospital stay, postoperative weight loss and postoperative albumin impairment. Results： Jejunostomy was performed in 40 on 109 patients（41.3%） who participated in quality of life investigation. A clinically and statistically significantly worse eating at admission（P=0.009） became not clinically significant at 3 months after surgery（MD =9.1）. Jejunostomy was associated to clinically and statistically significantly poorer emotional function（EF） at 3 months after surgery（MD =-15.6; P=0.04）. Hospital stay was longer in jejunostomy group（median, 20 vs. 17 days, P=0.02）.conclusions： In our series patients who had a jejunostomy during esophagectomy had been selected for their risk for postoperative complication. However, their postoperative outcome was actually similar compared to those without jejunostomy. Nevertheless, jejunostomy was associated to clinically and statistically significantly poorer EF at 3 months after surgery. Therefore, patient candidate to esophagectomy and feeding jejunostomy should receive additional psychological support.

The objective of this study was to evaluate the concentration and distribution of heavy metals in the sediments of Paulo Gorski Lake, as well as the metals’ bioavailability and potential ecological risk, and to define the anthropogenic and natural heavy metal contributions to the lake. The chemical elements calcium(ca), cadmium(cd), cobalt(co), chromium(cr), copper(cu), iron(Fe), potassium(K), magnesium(Mg), manganese(Mn), sodium(Na), nickel(Ni), lead(Pb), and zinc(Zn) were quantified by flame atomic absorption spectrophotometry with two extraction methods to quantify the bioavailable and nonbioavailable fractions. The data were evaluated using multivariate statistics and sediment quality *** sediment collection points(S1, S2, S3, S4 and S5) are different in terms of the concentration of heavy metals, except for S4 and S5, which were statistically equal. The bioavailable fraction of the elements in the sediment follows the sequence Pb > cu > Mn > Zn > Ni > cr > phosphorus(P) for all points. The elements co, cr, Pb, and Zn showed moderate to considerable contamination at all points. Only points S3 and S5 had moderate ecological risk. Urbanization has been affecting Paulo Gorski Lake via the input of chemical elements, especially co and Pb. The points most affected by heavy metal contamination are S3 and S5 when the sedimentological sensitivity factor is considered. The lake has high hydrodynamics,causing some of the contaminants that enter the system to leave it, leading to potential negative impacts downstream.

AIM: To evaluate the prevalence of HFE gene mutation and indices of disturbed iron homeostasis in alcoholics with and without liver ***: One hundred and fifty-three heavy drinkers (defined as alcohol consumption > 80 g/d for at least 5 years) were included in the study. These comprised 78 patients with liver disease [liver disease alcoholics (LDA)] in whom the presence of liver disease was confirmed by liver biopsy or clinical evidence of hepatic decompensation, and 75 subjects with no evidence of liver disease, determined by normal liver tests on two occasions [non-liver disease alcoholics (NLDA)], were consecutively enrolled. Serum markers of iron status and HFE c282Y and H63D mutations were determined. HFE genotyping was compared with data obtained in healthy blood donors from the same geographical ***: Gender ratio was similar in both study groups. LDA patients were older than NLDA patients (52 ± 10 years vs 48 ± 11 years, P = 0.03). One third and one fi fth of the study population had serum transferrin saturation (TS) greater than 45% and 60% respectively. Serum iron levels were similar in both groups. However, LDA patients had higher TS (51 ± 27 vs 36 ± 13, P capacity (TIBc) (241 ± 88 μg/dL vs 279 ± 40 μg/dL, P = 0.001). The odds ratio for having liver disease with TS greater than 45% was 2.20 (95% confi dence interval (cI): 1.37-3.54). There was no difference in c282Y allelic frequency between the two groups. However, H63D was more frequent in LDA patients (0.25 vs 0.16, P = 0.03). LDA patients had a greater probability of carrying at least one HFE mutation than NLDA patients (49.5% vs 31.6%, P = 0.02). The odds ratio for LDA in patients with H63D mutation was 1.57 (95% cI: 1.02-2.40).cONcLUSION: The present study confirms the presence of iron overload in alcoholics, which was more severe in the subset of subjects with liver disease,
