To compound matters, these issues are magnified during drought. Without adequate management and planning, drought impacts are likely to become more severe. This study focused on drought management plans of major cities in Alabama. However, it is important to understand how Alabama’s approach compares with other regions, particularly those with greater experience with drought. For this task we chose California. We selected the seven most populated cities in Alabama and seven cities of comparable population in California for the study. We then evaluated their drought plans based on the overall scope of the plan, three key elements of sustainable policy (social, environmental, and economic), and three stages of drought management (pre-, during-, and post-drought). Alabama and California plans received similar scores for the overall scope and the during-drought period. However, Alabama plans completely neglected the pre-drought period, were less comprehensive in all other areas, substantially weaker in detail, and lacking in enforcement and penalties. Furthermore, most Alabama plans were not available online to the public; whereas all California plans were available online and included public participation in the design process.","PeriodicalId":45528,"journal":{"name":"Southeastern Geographer","volume":"61 1","pages":"31 - 48"},"PeriodicalIF":0.7,"publicationDate":"2021-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1353/sgo.2021.0003","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46946372","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Aerosolization during laparoscopic interventions in Covid-19 patients may pose an increased risk to surgical staff and patients. Methods: We briefly review the inconceivably fast emerging studies for laparoscopy during the Covid-19 era and announce our practical method of surgical plume filtration during laparoscopic procedures of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) positive patients. Results: The use of minimally invasive surgery can be considered appropriate, safe and feasible in patients with Covid-19 and the use of trocar filtration systems reduces considerably the risks of infection. Conclusions: Despite the little evidence of viral transmission through laparoscopic surgical approach, modifications in surgical practice are recommended, such as the use of filtrating systems in order to minimize staff exposure to aerosolized viral particles.

Kuderova, S. Suprun, O. Lebed’ko","doi":"10.15789/1563-0625-sgo-2049","DOIUrl":"https://doi.org/10.15789/1563-0625-sgo-2049","url":null,"abstract":"The prevalence of bronchial asthma has shown its steady increase in the world in recent years. Despite all the achievements of Allergology, control of the disease can be achieved only in two-thirds of patients even if all social risk factors and the influence of concomitant diseases are excluded. Thus, it is necessary to study endogenous factors that modify the pathogenesis of the disease. Toll-like receptors are the main molecules for recognizing pathogenic patterns in the human immune system. Since any Allergy is a recognition error, mutation of the genes of the recognizing molecules can have a direct and multidirectional effect on the nature of the inflammation and its clinical manifestations in bronchial asthma (BA). To detect this effect, 65 patients with BA were examined, and mutations of Toll-like receptor genes were detected: TLR2-Arg753Glu, TLR4- Asp299Gly, TLR4-Ghr399Ile, TLR9-T1237C, TLR9-A2848G, lymphocyte subpopulations CD3, CD19, CD4, CD8, CD16, phagocytosis indicators, levels of IgA, IgM, IgG, IgE and IL-6, IL-7, IL-9. The assessment of the severity of asthma and its level of control were conducted according to clinical recommendations of the Ministry of health of the Russian Federation in 2019 criteria. We have shown characteristic clinical manifestations of the studied mutations. A lighter course of the disease, more complete control over it and a better response to therapy were found in single-nucleotide substitutions in the Toll-like receptor 4 and 9 (TLR4-Asp299Gly, TLR4-Ghr399Ile, TLR9-T1237C, TLR9-A2848G). On the contrary, a heavier course and a worse response to therapy were detected in the TLR2 mutation with Arg753Glu replacement. In the studied groups, the features of immunity indicators characteristic of genotypes with a lighter and more controlled course of BA were determined: a higher absolute number of T-helpers, with multidirectional changes in the number of T-killers, but with invariably preserved higher ratio of CD4/CD8 in such genotypes. Higher levels of phagocytosis indicators (primarily characterizing chemotaxis) and IL-7, IL-9 were also detected. The exception is the TLR9-A2848G mutation, in which greater disease control and better response to therapy are combined with no changes in the studied laboratory characteristics. At the same time, a specific feature of the genotype of the studied patients with BA was revealed – a combination of Toll-like receptors 4 and 9 mutations. This suggests the presence of genetic patterns that characterize groups of patients with BA that differ in severity, response to therapy, and degree of control, which makes it possible to personalize approaches to diagnosis, prevention, and therapy of the disease.","PeriodicalId":45528,"journal":{"name":"Southeastern Geographer","volume":"22 1","pages":"915-924"},"PeriodicalIF":0.7,"publicationDate":"2020-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43580476","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our analysis discovered anomalous clusters of these establishments in the immediate vicinity of the old Dixie Highway system. This nascent highway system acted as a significant driver of tourism and commercial development during the early 20th century. To verify the overrepresentation of “dixie” names along the route, we approximated the methods of prior studies, recording all instances of “dixie” from approximately 1,600 phone book directories in the contiguous 48 United States and mapping them by ZIP Code. Using this method, we find 39 percent of instances of “dixie”, in the ten states the system crossed, lie within a 0.5-kilometer buffer of the route. After removing these instances, we demonstrate that their exclusion significantly shrinks the regional hotspot. We conclude that prior scholarship utilizing this technique has inflated the size of the region by including instances of establishments named “dixie” to signal close proximity to the Dixie Highway system. Likewise, we conclude that qualitative scholarship on naming conventions, as well as the theoretical basis for using aggregated names as proxies for vernacular regions, are underdeveloped, and further work is needed in both areas.","PeriodicalId":45528,"journal":{"name":"Southeastern Geographer","volume":"60 1","pages":"345 - 359"},"PeriodicalIF":0.7,"publicationDate":"2020-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1353/sgo.2020.0028","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44793525","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One important feature of longleaf pine is its episodic nature of cone production that is required for successful regeneration. To learn more about individual-tree dynamics of longleaf pine cone production, this study investigates the concept of “super producers” — a small number of individuals that produce a disproportionally large volume of annual seed crop compared to standard producers. I examined a 29-year cone-production dataset provided by the U.S. Forest Service that contained 234 longleaf pine trees from 18 sites throughout the Southeast. I found super-producing individuals at each site and these trees comprised 16.4 percent of all trees that were able to produce 31.6 percent of all cones in the dataset. Super producers were largely indistinguishable from standard producers based on trunk diameter, yet they were able to produce large cone crops when standard producers could not. The results of this study reveal a new understanding of the substantial variability of cone production at the individual-tree level that should be considered when managing regeneration efforts.","PeriodicalId":45528,"journal":{"name":"Southeastern Geographer","volume":"60 1","pages":"332 - 344"},"PeriodicalIF":0.7,"publicationDate":"2020-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1353/sgo.2020.0027","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45756195","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
