Surgical approach to abdominal wall defects: history and new trends

AbstractWe briefly outline the history of hernia surgery development from the Ebers Papyrus to modern prosthetic repairs. The rapid evolution of anatomical, physiological and pathogenetic concepts has involved the rapid evolution of surgical treatments. From hernia sack cauterization to sack ligation, posterior wall repair (Bassini), and prosthetic reinforcement there has been an evident improvement in surgical treatment results that has stimulated surgeons to find new technical solutions over time. The introduction of prosthetic repair, the laparoscopic revolution, the impact of local anesthesia and the diffusion of day surgery have been the main advances of the last 50 years. Searching for new gold standards, the introduction of new devices has also led to new complications and problems. Research of the last 10 years has been directed to overcome prosthetic repair complications, introducing every year new meshes and materials. Lightweight meshes, composite meshes and biologic meshes are novelties of the last few years. We also take a look at future trends

Potential host ranges of three Asian larval parasitoids of Drosophila suzukii

AbstractAsobara japonica (Hymenoptera: Braconidae), Ganaspis brasiliensis and Leptopilina japonica (Hymenoptera: Figitidae) are Asian larval parasitoids of spotted wing drosophila, Drosophila suzukii (Diptera: Drosophilidae). This study evaluated these parasitoids' capacity to attack and develop from 24 non-target drosophilid species. Results showed that all three parasitoids were able to parasitize host larvae of multiple non-target species in artificial diet; A. japonica developed from 19 tested host species, regardless of the phylogenetic position of the host species, L. japonica developed from 11 tested species; and G. brasiliensis developed from only four of the exposed species. Success rate of parasitism (i.e., the probability that an adult wasp successfully emerged from a parasitized host) by the two figitid parasitoids was low in hosts other than the three species in the melanogaster group (D. melanogaster, D. simulans, and D. suzukii). The failure of the figitids to develop in most of the tested host species appears to correspond with more frequent encapsulation of the parasitoids by the hosts. The results indicate that G. brasiliensis is the most host specific to D. suzukii, L. japonica attacks mainly species in the melanogaster group and A. japonica is a generalist, at least physiologically. Overall, the developmental time of the parasitoids increased with the host's developmental time. The body size of female A. japonica (as a model species) was positively related to host size, and mature egg load of female wasps increased with female body size. We discuss the use of these parasitoids for classical biological control of D. suzukii

FLAMMABILITY OF ORNAMENTAL SPECIES FOR FIRE MANAGEMENT IN WILDLAND-URBAN INTERFACE IN PARANÁ STATE

The objective of this work was to evaluate the flammability of ornamental species as a tool for fire management in areas of wildland-urban interface in Paraná. For this, native ornamental species and exotic species were selected. Initially, the following morphological characteristics of the leaves, which are associated with the flammability of the selected species were evaluated: texture, exudates, hairiness and enervation. The flammability characteristics of the species were analyzed through burning experiments. Fifty 1g burns of freshly harvested plant material of each species were conducted in an epiradiator. The variables collected were: ignition frequency (FI), time to ignition (TI), combustion duration (DC) and combustion index (CI). These variables were statistically analyzed by the SNK test at 95% probability. The Cluster test was also performed to identify different levels of flammability of the species tested as a function of the morphological characteristics and the flammability parameters obtained in the epiradiator tests. The results showed that FI and TI were lower in most native species (except Verbena rigida), differing statistically from exotic ones. There were differences among the species as a function of the species leaf morphology and the flammability parameters measured during the burning. It can be inferred that most native species may have been considered slightly flammable and exotic as flammable, with the exception of the species Euonymus japonica, classified as zero flammability, concluding that native species are the most suitable for use in fire management in wildland-urban interface areas in Paraná, and should be intensively used in landscaping

THE INFLUENCE OF STREET TREES ON URBAN MICROCLIMATE

The microclimatic improvement is often cited as one of the benefits generated by urban trees, however, there are few studies which quantitatively address this effect. The aim of this paper was to compare the microclimate of streets with and without trees. Therefore, three samples containing a stretch of street with and without trees were selected, with the street with trees being composed of different species. The temperature, relative humidity and wind speed data were measured by automatic Kestrel® meteorological ministations installed on the street with trees and another in the street without trees. The data collection period was from 9 AM to 3 PM, and the monitoring interval was every 1 minute during all four seasons starting in the winter of 2011. The comparative analyses were done using the Student’s t-test (99%). The results indicated that the air temperature in a street with trees was on average 1.7 °C lower than a street without trees, the relative humidity was 6.9% higher and the wind speed was 0.04 m/s lower.  There was no statistical difference for temperature between the street with “ipê” in the winter and spring. There was no difference for wind speed in the summer between the street with other trees and the street with “ipê” and “tipuana”. It was concluded that street trees provide a pleasant microclimate, and this influence was statistically significant

Major postoperative complications and survival for colon cancer elderly patients

BACKGROUND: Increased life expectancy has led to elevating the mean age of the patients at the time of diagnosis of colon cancer and subsequent treatment. Differences in complication rates and outcome between elderly and younger patients have been investigated. METHODS: We retrospectively analysed a database containing the information of patients who underwent surgery for stage I-III colorectal cancer from January 2004 to January 2012 at our institution and compared demographic, cancer-related, and outcomes data of 235 elderly patients with 211 patients ≤65 years old. RESULTS: Intraoperative complications did not differ between young and old patients whereas some differences have been found in postoperative and late complications: elderly patients suffered more by ileus (P = 0.024), peritonitis or septic shock (P = 0.017), pelvic abscess (P = 0.028), wound infection (P = 0.031), and incisional/port herniation (P = 0.012) compared with younger patients. Moreover, elderly patients suffered by systemic complications such as cardiovascular (4.7% vs. 1.4%, P = 0.049), renal (4.7% vs. 0.5%, P = 0.006), and respiratory (10.6% vs. 5.2%, P = 0.036). The multivariate analysis assessing the odds of having a complication revealed that older age (Odd Ratio [OR] 2.75, 95% Confidential Interval [CI]: 1.67-4.52) and open surgery (OR 1.63, 95% CI: 1.01-2.62) are significantly and independently associated with having a complication. CONCLUSIONS: In our series, elderly patients have presented a slight higher incidence of comorbidities that may affect the incidence rates of postoperative complications. These results have implications in increasing the hospital stay as well as a higher rate of death

BIBLIOMETRIC REVIEW OF THE FOREST AS A TOOL FOR ENVIRONMENTAL EDUCATION

The contact with the forest started in childhood enables the construction of values with nature. Bibliometric studies can help in the search for works on the forest theme. Thus, the objective of this work was to analyze the general panorama of scientific research on environmental education activities related to the forest, through bibliometric characterization in WoS and Scopus databases. The works were filtered from search codes that covered the theme. All articles were checked, and those that carried out environmental education activities and used the forest as a base were considered valid. The filtering resulted in 102 articles, of these, 62 articles it was possible to carry out a methodological analysis. Articles from 37 countries were found, with a greater number for the USA and 274 different authors, but the majority (93.4%) published only one manuscript. In the methodological analysis, most include non-formal teaching in specific environmental education activities. The forest in general is used for works focused on environmental perception and awareness, and the most used environmental interpretation techniques are field practices, in guided and self-guided interpretive trails. More than 50% of the articles do not justify the applied method and several works show methodological flaws that make it difficult to replicate the practices in other studies. It is concluded in the bibliometric analysis that there are a variety of authors talking about the subject, but a reference specialist author was not identified. The methodological flaws found prove the challenges of obtaining scientific advances in environmental education from the forest

Resumption of day surgery activity in the acute phase of COVID-19 pandemic

The rapid spread of COVID-19 disease since February 2020 has strongly impacted on the Healthcare System worldwide, who above all was forced to ensure the treatment of the COVID infected patients primarily. Then, the elective surgical procedures were limited to oncology, even stopping any Day Surgery (DS) activities. In Italy more than DS 650.000 procedures have been delayed. Day surgery commonly is performed in free-standing units or in dedicated hospital areas, with separated access to spaces for admission and dedicated operating rooms, allowing a lower risk of contamination during hospitalization.1 The implementation of protocols and recommendations, and a new planning of the pathways, can ensure an early restart of daily surgery procedures, regardless of the pandemic trend

Interleukin-1 blockade in recently decompensated systolic heart failure: study design of the recently decompensated heart failure anakinra response trial (RED-HART)

Heart Failure (HF) is a clinical syndrome characterized by dyspnea, fatigue, and poor exercise capacity due to impaired cardiac function. The incidence of HF is increasing and represents the leading cause of hospitalization in the United States among patients > 65 years of age. Neurohormonal blockade has proven to reduce morbidity and mortality; however the persistent toll of HF demonstrates the urgent need to continue to develop novel drugs that target other pathophysiological paradigms. The presence of inflammation in cardiovascular disease has been well-established and interleukin-1 (IL-1), the prototypical proinflammatory agent, has been shown in preclinical animal models to induce cardiac dysfunction. The current study will investigate the role of IL-1 as an inflammatory mediator of HF progression and investigate whether IL-1 blockade with anakinra, recombinant human IL-1 receptor antagonist, improves aerobic exercise performance in patients with recently decompensated systolic HF. This study will be composed of 3 treatment arms (20 patients each): 1) anakinra 100mg daily for 12 weeks; 2) anakinra 100mg daily for 2 weeks followed by placebo for 10 weeks; or 3) placebo for 12 weeks. All patients will be followed for at least 24 weeks. The co-primary endpoints will be placebo-corrected interval changes in peak oxygen consumption (VO2) and ventilatory efficiency (VE/VCO2 slope) measured by Cardiopulmonary Exercise Testing (CPX) after 2 weeks of anakinra treatment. Secondary endpoints will include interval changes in 1) CPX variables at 4, 12 and 24 weeks; 2) echocardiographic measures of cardiac dimension/function; 3) quality of life assessments; 4) inflammatory biomarkers; and 5) clinical outcome including days alive outside of the hospital and survival free of re-hospitalization for HF. The RED-HART study will be the first study to address the potential benefits of IL-1 blockade on aerobic exercise performance in patients with recently decompensated HF
