Abstract 40: Global Cancer Surgery in Low-Resource Settings: A Strengths, Weaknesses, Opportunities, and Threats Analysis

Abstract Background: Cancer surgery is a resource-intensive yet essential component of cancer care. In the face of projected increase in cancer burden, the present gap in cancer surgery care in low-resource settings with stressed healthcare and surgical infrastructure risks further exacerbation. Understanding the current state of global cancer surgery is essential to determining the best way forward. Purpose: The objectives of this report are to (1) describe the landscape of global cancer surgery literature and (2) characterize these findings through a Strengths, Weaknesses, Opportunities, and Threats (SWOT) analysis. Methods: A literature review was performed of global cancer surgery studies involving low-resource settings published since the landmark 2015 Lancet Commission on Global Surgery and Global Cancer Surgery. Studies were summarized and evaluated for themes, which were further grouped into SWOT categories for analysis. Results: The online literature search yielded 123 articles, of which 46 articles met inclusion criteria for analysis. The majority of included studies were open access (n=34) and published between 2021 and 2022 (n=26). Conclusion: The body of published global cancer surgery literature is growing, perhaps reflecting increased research attention and valuation. From the reviewed literature, Strengths of the global cancer surgery field include a body of studies investigating important aspects of cancer surgery in low-resource settings: local cancer epidemiology, local surgical and technological innovation, quality-of-life as a key surgical outcome metric, and advancements in cancer surgery through interdisciplinary work. Weaknesses include systems-level limitations (i.e. resources, perioperative services, broader health system gaps) and a paucity of detailed economic analyses. Opportunities include diverse local cancer management strategies, successful inter-setting collaborations supporting research, education, and surgical skills training, and thoughtful research expansion for an inclusive future. Threats include large-scale stresses on local healthcare infrastructure (i.e. COVID-19) and the risk of widening disparities posed by unchecked technological. Conclusion: This SWOT analysis may inform local intervention strategies and action plans to help LMIC stakeholders achieve cancer surgery goals. Similar analyses are needed locally to help elucidate best practices that might be applied or tailored to similar settings globally. Citation Format: Samantha Sadler, Erick Torio, Alexandra Golby.

Combining genetic local search into a multi-population Imperialist Competitive Algorithm for the Capacitated Vehicle Routing Problem

The Vehicle Routing Problem (VRP) is one of the most significant problems in operational research today. VRP has a vast range of application fields such as transportation, logistics, manufacturing, relief systems and communication. To suit the needs of different real-world VRP scenarios, many models of VRP have been developed — CVRP (Capacitated VRP) being the classical form. In this article, a hybrid metaheuristic algorithm, ICAHGS, is proposed for solving CVRP. The present study proposes a refined Imperialist Competitive Algorithm (ICA) as the primary evolutionary and multi-population method for addressing the Capacitated Vehicle Routing Problem (CVRP). In order to further optimize the search process, a Hybrid Genetic Search (HGS-CVRP) algorithm is applied as an enhanced local search and population management strategy within the ICA framework. Additionally, the internal restart step of the HGS-CVRP algorithm is replaced with a multi-step restart mechanism for intensification improvement. One notable aspect of the proposed method is its ability to facilitate parallel processing, with each empire able to be processed on a separate processor. This structure allows for increased computational efficiency in addressing the CVRP. To assess the effectiveness of the proposed algorithm, it has been compared to several state-of-the-art algorithms from the literature. The results of this comparison, which include both classical benchmark instances and real-world applications, demonstrate the competitive performance of the proposed algorithm.

Spatial variation in red deer density in a transboundary forest ecosystem

Forests in Europe are exposed to increasingly frequent and severe disturbances. The resulting changes in the structure and composition of forests can have profound consequences for the wildlife inhabiting them. Moreover, wildlife populations in Europe are often subjected to differential management regimes as they regularly extend across multiple national and administrative borders. The red deer Cervus elaphus population in the Bohemian Forest Ecosystem, straddling the Czech-German border, has experienced forest disturbances, primarily caused by windfalls and bark beetle Ips typographus outbreaks during the past decades. To adapt local management strategies to the changing environmental conditions and to coordinate them across the international border, reliable estimates of red deer density and abundance are highly sought-after by policymakers, wildlife managers, and stakeholders. Covering a 1081-km2 study area, we conducted a transnational non-invasive DNA sampling study in 2018 that yielded 1578 genotyped DNA samples from 1120 individual red deer. Using spatial capture-recapture models, we estimated total and jurisdiction-specific abundance of red deer throughout the ecosystem and quantified the role of forest disturbance and differential management strategies in shaping spatial heterogeneity in red deer density. We hypothesised that (a) forest disturbances provide favourable habitat conditions (e.g., forage and cover), and (b) contrasting red deer management regimes in different jurisdictions create a differential risk landscape, ultimately shaping density distributions. Overall, we estimated that 2851 red deer (95% Credible Interval = 2609–3119) resided in the study area during the sampling period, with a relatively even overall sex ratio (1406 females, 95% CI = 1229–1612 and 1445 males, 95% CI = 1288–1626). The average red deer density was higher in Czechia (3.5 km−2, 95% CI = 1.2–12.3) compared to Germany (2 km−2, 95% CI = 0.2–11). The effect of forest disturbances on red deer density was context-dependent. Forest disturbances had a positive effect on red deer density at higher elevations and a negative effect at lower elevations, which could be explained by partial migration and its drivers in this population. Density of red deer was generally higher in management units where hunting is prohibited. In addition, we found that sex ratios differed between administrative units and were more balanced in the non-intervention zones. Our results show that the effect of forest disturbances on wild ungulates is modulated by additional factors, such as elevation and ungulate management practices. Overall density patterns and sex ratios suggested strong gradients in density between administrative units. With climate change increasing the severity and frequency of forest disturbances, population-level monitoring and management are becoming increasingly important, especially for wide-ranging species as both wildlife and global change transcend administrative boundaries.

Subsistence and animal management at Iron Age sites of Quanshuigou and Dumuduebudege in western Xinjiang, China

AbstractXinjiang sits in the northwesternmost part of China and played an active role in facilitating the flow of technologies, cultivars, and livestock long before the Silk Road. While mixed pastoralism was developed in neighboring Central Asia, the local lifeways in Xinjiang, as well as the possible interactions in‐between these regions, have still not been fully understood. Here, we conduct zooarchaeological analyses at two Iron Age sites of Quanshuigou and Dumuduebudege in western Xinjiang, to clarify the local subsistence and animal management strategies. Our results reveal that sheep/goats were the most exploited animals in this region, followed by horses and cattle in the managed herd. Apart from meat and marrow, renewable secondary products such as wool and milk might also be used, suggesting an intensive livestock exploitation managed by the local pastoral communities. Such mixed pastoralism not only continues throughout the Iron Age but also is visible today in Xinjiang, demonstrating its profound and lasting influence for nomadic groups in this region.

Future changes and driving factors of global peak vegetation growth based on CMIP6 simulations

Accurate detection and attribution of changes in global peak vegetation growth at the annual scale are prerequisites for characterising the productivity of terrestrial ecosystems and developing strategies for the sustainable management of ecosystems. This study examined the long-term global normalised difference vegetation index during the baseline period (1982–2015) and found widespread greening in 70% of global vegetated areas in response to climate warming. However, climate change is not the only cause of global greening. The spatial variability in the response of global vegetation to environmental factors has not been well established. The Cubist model was used to investigate the relationship between peak vegetation growth and environmental variables. The results showed that 64% of the spatial variation in greening/browning can be explained by climate (including precipitation and temperature), followed by atmospheric components of nitrogen deposition and carbon dioxide concentration (17%), terrain properties (12%), and soil properties (7%). By incorporating future climate and atmospheric component projections from the Coupled Model Intercomparison Project Phase 6 into the model, enhanced vegetation greening was predicted globally, particularly in evergreen needle-leaf forests and grasslands, from 2081 to 2100. Many browning changes were predicted in evergreen and deciduous broadleaf forests, mixed forests, and around areas influenced by human land use. Overall, these findings reveal that environmental factors have relevant integrated impacts on vegetation dynamics under climate change and should be considered during the design of local mitigation and adaptation management strategies.

A phase II study of nivolumab with ipilimumab and cabozantinib in patients with untreated renal cell carcinoma brain metastases.

TPS745 Background: A SEER analysis from 2010 to 2013 demonstrated that the incidence of brain metastases(mets) at the diagnosis of renal cell carcinoma(RCC) is 1.51%, and around 12% of patients(pts) with advanced RCC (aRCC) also had mets to the brain. Brain mets confer a poor prognosis. Local management strategies for brain mets from RCC include surgical resection, stereotactic radiosurgery and whole brain radiation therapy. Although systemic therapies including tyrosine kinase inhibitors and immune checkpoint inhibitors have been explored in aRCC pts with brain mets, prospective data is lacking. Cabozantinib is a potent small molecule inhibitor of multiple tyrosine kinases that was approved by FDA for pts with aRCC alone or in combination with nivolumab. Cabozantinib has demonstrated activity in patients with intracranial tumors. A phase III trial (COSMIC-313) recently evaluated cabozantinib in combination with nivolumab and ipilimumab compared to nivolumab plus ipilimumab and demonstrated significantly improved progression-free survival (PFS) in previously untreated pts with aRCC. The combination was found to be safe as frontline systemic treatment. The role of this combination in patients with aRCC with brain mets remains undefined. As such, we propose a study to assess the safety and efficacy of cabozantinib in combination with nivolumab/ipilimumab in RCC pts with untreated brain mets. We believe the results from this trial could provide additional treatment options for pts with RCC brain mets who are typically excluded from clinical trials. Methods: This is a phase II study to assess the safety and efficacy of the combination of nivolumab with ipilimumab and cabozantinib in pts with untreated brain mets from RCC until disease progression or intolerable toxicities or patient withdrawal. Planned accrual is 40 pts. Pts will be treated with nivolumab (3mg/kg) and ipilimumab (1mg/kg) IV every 3 weeks for 4 doses and cabozantinib 40mg daily. Then pts will be treated with nivolumab 480mg IV Q 4 weeks and cabozantinib 40mg daily until progression or intolerable toxicities or patient’s withdrawal. A lead-in group of 6 pts will be closely monitored for dose limiting toxicities(DLT). If stopping criteria (>3 patients develop DLTs) is met, then treatment will be switched to nivolumab plus cabozantinib omitting ipilimumab. The primary objective is intracranial progression free survival(PFS). Secondary objectives include intracranial safety, objective response rate (intracranial + extracranial) by modified RECIST v1.1 and RECIST v1.1, extracranial PFS and overall survival. This phase II trial is currently enrolling pts. Clinical trial information: NCT05048212 .

Cetacean distribution and relative abundance in Colombia’s Pacific EEZ from survey cruises and platforms of opportunity

Cetacean sighting data collected under various programmes in Colombian Pacific waters were collated with the goal of assessing the distribution and abundance patterns of all species occurring in the exclusive economic zone (EEZ). Distribution maps are presented for 19 species and one genus based on 603 sightings collected between 1986 and 2008. Ordered by sighting frequency, these species were: humpback whale (Megaptera novaeangliae); striped dolphin (Stenella coeruleoalba); common bottlenose dolphin (Tursiops truncatus); pantropical spotted dolphin (Stenella attenuata); common dolphin (Delphinus delphis); Risso’s dolphin (Grampus griseus); sperm whale (Physeter macrocephalus); rough-toothed dolphin (Steno bredanensis); short-finned pilot whale (Globicephala macrorhynchus); mesoplodont whales (Mesoplodon spp.); Cuvier’s beaked whale (Ziphius cavirostris); melon-headed whale (Peponocephala electra); false killer whale (Pseudorca crassidens); killer whale (Orcinus orca); spinner dolphin (Stenella longirostris); dwarf sperm whale (Kogia sima); Bryde’s whale (Balaenoptera edeni); pygmy killer whale (Feresa attenuata); minke whale (Balaenoptera acutorostrata) and fin whale (Balaenoptera physalus). Concentrations of sightings were observed in three geographic areas: (1) the continental shelf (depths <200m) and the contiguous continental slope (200–2,000m); (2) over the Malpelo Ridge, an offshore bathymetric feature and (3) the northeast corner of the EEZ between Golfo de Cupica and the border with Panamá, although we do not rule out that these patterns could be an artefact of non-random effort. In inshore waters, the most frequently seen species were pantropical spotted dolphin, common bottlenose dolphin and humpback whale. For several of the data sets we provide encounter rates as indices of relative abundance, but urge caution in their interpretation because of methodological limitations and because several factors that affect sightability could not be accounted for in these estimates. Our results provide useful information for ongoing regional research and conservation initiatives aimed at determining occurrence, population status and connectivity within adjacent EEZs in the eastern tropical Pacific. Suggested research priorities include conducting dedicated surveys designed for estimating abundance and monitoring trends throughout the EEZ and focused studies in areas of special interest like the continental shelf, the Malpelo Ridge and the vicinity of Cupica and Cabo Marzo. More research is also needed in terms of quantifying the sources and impact of anthropogenic mortality on population size. Studies characterising genetic diversity and stock discreteness in coastal species (pantropical spotted dolphin and common bottlenose dolphin) would help inform local management strategies.

A simplified multi-model statistical approach for predicting the effects of forest management on land surface temperature in Fennoscandia

Forests interact with the local climate through a variety of biophysical mechanisms. Observational and modelling studies have investigated the effects of forested vs. non-forested areas, but the influence of forest management on surface temperature has received far less attention owing to the inherent challenges to adapt climate models to cope with forest dynamics. Further, climate models are complex and highly parameterized, and the time and resource intensity of their use limit applications. The availability of simple yet reliable statistical models based on high resolution maps of forest attributes representative of different development stages can link individual forest management practices to local temperature changes, and ultimately support the design of improved strategies. In this study, we investigate how forest management influences local surface temperature (LSTs) in Fennoscandia through a set of machine learning algorithms. We find that more developed forests are typically associated with higher LST than young or undeveloped forests. The mean multi-model estimates from our statistical system can accurately reproduce the observed LST. Relative to the present state of Fennoscandian forests, fully develop forests are found to induce an annual mean warming of 0.26 °C (0.03/0.69 °C as 5th/95th percentile), and an average cooling effect in the summer daytime from -0.85 to -0.23 °C (depending on the model). On the contrary, a scenario with undeveloped forests induces an annual average cooling of -0.29 °C (-0.61/-0.01 °C), but daytime warming in the summer that can be higher than 1 °C. A weak annual mean cooling of -0.01 °C is attributed to forest harvest from 2015 to 2018, with an increased daytime temperature in summer of about 0.04 °C. Overall, this approach is a flexible option to study effects of forest management on LST that can be applied at various scales and for alternative management scenarios, thereby helping to improve local management strategies with consideration of effects on local climate.

Unifying biological field observations to detect and compare ocean acidification impacts across marine species and ecosystems: what to monitor and why

Abstract. Approximately one-quarter of the CO2 emitted to the atmosphere annually from human activities is absorbed by the ocean, resulting in a reduction of seawater pH and shifts in seawater carbonate chemistry. This multi-decadal process, termed “anthropogenic ocean acidification” (OA), has been shown to have detrimental impacts on marine ecosystems. Recent years have seen a globally coordinated effort to measure the changes in seawater chemistry caused by OA, with best practices now available for these measurements. In contrast to these substantial advances in observing physicochemical changes due to OA, quantifying their biological consequences remains challenging, especially from in situ observations under real-world conditions. Results from 2 decades of controlled laboratory experiments on OA have given insight into the likely processes and mechanisms by which elevated CO2 levels affect biological process, but the manifestation of these process across a plethora of natural situations has yet to be fully explored. This challenge requires us to identify a set of fundamental biological and ecological indicators that are (i) relevant across all marine ecosystems, (ii) have a strongly demonstrated link to OA, and (iii) have implications for ocean health and the provision of ecosystem services with impacts on local marine management strategies and economies. This paper draws on the understanding of biological impacts provided by the wealth of previous experiments, as well as the findings of recent meta-analyses, to propose five broad classes of biological indicators that, when coupled with environmental observations including carbonate chemistry, would allow the rate and severity of biological change in response to OA to be observed and compared. These broad indicators are applicable to different ecological systems, and the methods for data analysis suggested here would allow researchers to combine biological response data across regional and global scales by correlating rates of biological change with the rate of change in carbonate chemistry parameters. Moreover, a method using laboratory observation to design an optimal observing strategy (frequency and duration) and observe meaningful biological rates of change highlights the factors that need to be considered when applying our proposed observation strategy. This innovative observing methodology allows inclusion of a wide diversity of marine ecosystems in regional and global assessments and has the potential to increase the contribution of OA observations from countries with developing OA science capacity.

Study of COVID-19 Epidemic Control Capability and Emergency Management Strategy Based on Optimized SEIR Model

Due to insufficient epidemic detection and control, untimely government interventions, and high epidemic prevention costs in the early stages of the epidemic outbreak, the spread of the epidemic may become out of control and pose a great threat to human society. This paper optimized and improved the traditional Susceptible-Exposed-Infectious-Removed (SEIR) model for investigating epidemic control and public health emergency management. Using the Corona Virus Disease 2019 (COVID-19) outbreak as an example, this paper simulates and analyzes the development of an epidemic outbreak during various periods with the optimized SEIR model, to explore the emergency control capacity of conventional medical control measures, such as large-scale outbreak testing capacity, hospital admission capacity, or daily protection of key personnel, and analyze the government’s emergency management strategies to achieve low-cost epidemic control. The model developed in this study and the results of its analysis demonstrate the differences in outbreak emergency control capacity under different conditions and different implementation strategies. A low-cost local outbreak emergency management strategy and the timing of the government’s resumption of work and school are discussed on this basis.

Length-Weight Relationship and Condition Factor of Prussian Carp (Carassius gibelio, Bloch, 1782) from Asi River

This study aimed to determine the length-weight relationship and condition factor of Prussian carp (Carassius gibelio, Bloch, 1782) from the Asi River. Samples were collected by 12-18 mm mesh sized fyke-nets between November and December 2021. Totally 88 specimens have been collected from the Turkish part of Asi River, Hatay, Türkiye. Lengths and weights ranged from 10.2 to 29.8 cm and 19.47 to 408.59 g, respectively. The b-values were calculated as 3.08 and the LWR equation was estimated as W = 0.0138*L3.08. The Fulton’s condition factor (K) and the relative condition factor (Kn) values were calculated as 1.76±0.03 and 1.01±0.01, respectively. This study provides the valuable data on the length-weight relationship and condition factors of C. gibelio from the Asi River. The findings of the present paper revealed that C. gibelio showed an isometric growth and this region is relatively suitable for the growth of this species. Therefore, these data will be a valuable background for further biological studies and local fisheries management strategies.

Red Deer in Lithuania: History, Status and Management

The history, current population status and (un)sustainable management of red deer (Cervus elaphus) in Lithuania are reviewed on the basis of 57 publications and, additionally, analysis of data on numbers and hunting bag. After the extinction of the species at the beginning of the 19th century, red deer were reintroduced into the northern part of the country during World War I. Population re-establishment was further fueled after WWII by immigration from neighboring countries and local translocations. After the introduction of the Law on Hunting in 2002, which enabled hunting organizations to rent hunting grounds for longer than 10 years, local wildlife management strategies were targeted at increasing the number of animals. However, a scientifically-based target population size for C. elaphus, agreed by all major stakeholders, has still not been defined. In the last 20 years, population growth has been exponential, deer numbers in Lithuania being estimated as 68,816 individuals in 2021. An increase in the size of the hunting bag is necessary for the sustainable management of the species at the national scale and to avoid risks of over-population as observed elsewhere in Europe.

Epicoccum layuense Causing Leaf Spot on Oxalis corymbosa in China.

Oxalis corymbosa DC. is a perennial herb used as the groundcover in the urban landscape and traditional Chinese medicine. In May 2019, a leaf spot-like disease was observed on about 20% of O. corymbosa plants in one park in Hefei, Anhui, China (N31°52´, E117°15´). Symptoms appeared as yellowish, irregular or circular areas that later turned pale brown, coalesced and produced large necrotic areas of various shapes. Ten leaves with typical symptoms were removed from 5 different O. corymbosa plants (2 leaves per plant) and disinfected with 75% ethanol for 30 s. The tissue pieces (4×4 mm) were cut from the margin of the leaf lesion, dipped in 2% NaClO for 1 minute, washed 3 times with sterile distilled water, placed on Potato Dextrose Agar (PDA) medium with 50 μg/ml each of ampicillin and kanamycin, and cultured at 25℃ under a 12-h light/dark cycle. The white mycelia grew out of each leaf tissue pieces 3 days later and the hyphal tips were sub-cultured into a new PDA medium for purification. After 5 days of incubation at 25℃, the produced colonies were yellow with irregular white margin from the top with floccose aerial mycelia, ranged in a diameter from 60 to 70 mm, and produced red orange pigments into PDA medium. Colonies on the reverse side were dark red. Conidia produced on PDA were ranged in size from 5.5 to 35.5 μm in diameter (n = 800), subglobose to pyriform, and yellowish-brown. The representative isolate YHF0519 was chosen for further analysis. Fragments of four genes including the internal transcribed spacer (ITS), beta-tubulin, 28S large subunit ribosomal RNA gene (LSU), and the second largest subunit of RNA polymerase II (RPB2) were amplified from the extracted genomic DNA of YHF0519 and sequenced. The corresponding primer sets were ITS1/ITS4 (White et al. 1990), Bt2a/Bt2b (Glass and Donaldson 1995), LSU1Fd/LR5 (Crous et al. 2009; Vilgalys and Hester 1990), and RPB2-5F2/fRPB2-7cR (Sung et al. 2007; Liu et al. 1999), respectively. All resulting sequences were deposited into GenBank and received assigned accession numbers: MN418006 for ITS; MN428043 for beta-tubulin; MN428044 for LSU; MZ437946 for RPB2. A phylogenetic tree generated by the maximum likelihood method with 1,000 bootstrapping replications based on the combined ITS, beta-tubulin, LSU, and RPB2 sequences revealed that YHF0519 was clustered closest to the isolate CGMCC 3.18362 of Epicoccum layuense Qian Chen, Crous & L. Cai (Chen et al. 2017; Jayasiri et al. 2017). The pathogenicity test was performed on leaves of healthy O. corymbosa plants in the field and repeated twice. The average air temperature was about 28°C during the pathogenicity test. A total of 126 and 127 leaves were used for treatment and control, individually. Leaves were inoculated by spraying 30 ml of spore suspension (1×106 spores/ml) of YHF0519 or sterilized distilled water. Eight day-post inoculation, about 92% of the leaves inoculated with spores developed pale brown spots, which are identical to those occurred naturally in the field. No symptoms were detected on control leaves. The fungus was re-isolated from the symptomatic leaf tissues and showed the same morphological and molecular characteristics as YHF0519. E. layuense has been reported on Perilla sp., oat, and tea plant (Chen et al. 2017; Chen et al. 2019; Chen et al. 2020). This is the first report of E. layuense causing leaf spot on O. corymbosa in China. Due to the potential threat on the ornamental and medicinal value of O. corymbosa by E. layuesne, it will be necessary to develop local management strategies against leaf spot on O. corymbosa.

Impacts of local conservation strategies on forest flora species of the Ambalara forest reserve in the Wa East District, Ghana

ABSTRACT Sustainable conservation of forest flora species is dependent on local conservation strategies. In the past, fringe communities of the Ambalara Forest Reserve were excluded from its conservation. In contemporary times, the participation of fringe communities in the conservation of forest flora species of the Ambalara Forest Reserve has been strengthened due to the Community Resource Management Area (CREMA) initiative. This study examines the impact of strategies used by local actors such as the land priest (tendaana), sectional heads, chiefs (naamene), diviners, women leaders (magazias) and youth groups on forest flora species of the forest reserve. The strategies used by local actors are taboos, creation of traditional firebelts, revered tree species, bans and awareness creation. The study reveals that, fringe communities endorse the chiefs (naamene) and the land priests (tendaana) as the most effective actors in the conservation of forest flora species of the reserve and the traditional fire belt creation as the most effective conservation strategy. The study concludes that, there exist local management actors and strategies in the conservation of forest flora species of the forest reserve, and fringe communities and the reserve are impacted positively by means of their engagement in alternative livelihood activities and species richness of forest flora species respectively. It is recommended that traditional awareness creation should be intensified by the chiefs and elders on the need to conserve forest flora species of the reserve for future generations and as a form of mitigating the effects of climate change on biodiversity.

Local management strategies for inflammatory vaginitis in dermatologic conditions: Suppositories, dilators, and estrogen replacement

Prevalence of vaginal involvement in erosive lichen planus and pemphigus vulgaris has been reported in over 58% and up to 44% of patients, respectively.1Khurana A. Tandon S. Marfatia Y.S. Madnani N. Genital lichen planus: an underrecognized entity.Indian J Sex Transm Dis AIDS. 2019; 40: 105-112Crossref PubMed Google Scholar,2Kavala M. Topaloğlu Demir F.

Here, we highlight 3 local strategies to target inflammatory vaginal dermatoses and prevent scarring (Fig 1). We recommend starting with 25-mg hydrocortisone acetate suppositories, available as rectal suppositories. Patients should be counseled to use vaginally instead of rectally. Suppositories are initiated nightly for 2 to 4 weeks and decreased to every other night, or 2 to 3 times per week depending on disease control. Patients should be evaluated monthly, and suppositories should be tapered to the lowest dose/frequency that maintains disease remission.2Kavala M. Topaloğlu Demir F.

When prescribing suppositories, we recommend candidal prophylaxis, with topical antifungals 2 to 3 times per week or oral fluconazole 150 to 200 mg weekly. Insertion of dilators 3 times, weekly, to prevent adhesions. Dilators can be ordered online and come in sets of varying sizes. Patients should use the largest dilator comfortable, and vaginal moisturizers and lubricants can be utilized. Estrogen deficiency should be considered in postmenopausal patients as this can contribute to vaginal inflammation. Local estrogen therapy includes a ring, tablet, or cream. Generally, vaginal cream tends to have the least pain with insertion and is used nightly for 2 weeks with decrease to maintenance 1 to 3 times per week. None disclosed.

Assessing the Spatiotemporal Relationship between Coastal Habitats and Fish Assemblages at Two Neotropical Estuaries of the Mexican Pacific

Differences in fish assemblages’ structures and their relations with environmental variables (due to the variations in sampled seasons, habitats, and zones) were analyzed in two adjacent estuaries on the north Pacific coast of Mexico. Environmental variables and fish catches were registered monthly between August 2018 and October 2020. Multivariate analyses were conducted to define habitats and zones based on their environmental characteristics, and the effect of this variability on fish assemblages’ composition, biomass, and diversity (α and β) was evaluated. A total of 12,008 fish individuals of 143 species were collected using different fishing nets. Multivariate analyses indicated that fish assemblages’ structures were different between zones due to the presence, height, and coverage of distinct mangrove species. Additionally, depth and salinity showed effects on fish assemblages’ diversity (α and β-nestedness), which presented higher values in the ocean and remained similar in the rest of the analyzed zones and habitats. These results and the differences in species replacement (β-turnover) indicate the singularity of fish assemblages at estuaries (even in areas close to the ocean) and the necessity to establish local management strategies for these ecosystems.

Local wound management: A review of modern techniques and products.

Management of wounds is a commonly performed and essential aspect of small animal veterinary medicine. Appropriate wound management is a difficult art to master, due to the inherent complexity of the clinical scenario, as well as the ever-evolving nature of the field with the constant addition of new products and techniques. This article reviews key concepts that may help the practitioner better understand the natural process of wound healing, factors that delay healing and strategies to help improve the local wound environment to make it more conducive to healing during open wound management. The concept of wound bed preparation is defined before common local wound management strategies, such as wound lavage and debridement, are discussed in more detail. Key aspects of the management of biofilms and appropriate use of antimicrobial agents are also reviewed. Finally, the concept of moist wound healing and its impact in modern wound management is explained before a broad variety of types of wound dressings are reviewed, with a particular focus on active dressings.

Evidence of Závora Bay as a critical site for reef manta rays, Mobula alfredi, in southern Mozambique.

The largest known reef manta ray (Mobula alfredi) population in Africa has been monitored for more than 20 years at several locations on the coast of the Inhambane Province in southern Mozambique. Nonetheless, before this study, little had been reported on the population dynamics of M. alfredi from Závora, a remote bay in the region. Photographic mark‐recapture was used to investigate the size and structure of M. alfredi that aggregate at “Red Sands,” a reef cleaning station in Závora Bay. An 11 year photographic data set was used to identify 583 M. alfredi individuals between 2010 and 2021. More than half of M. alfredi individuals were resighted at least once, with most encounters (up to 18 for one individual) occurring during the peak sighting period in July–November each year. An even sex ratio was observed, 44% females and 50% males, with no significant difference in resightings between the sexes. Pollock's robust design population models were used to estimate annual abundance, emigration, annual apparent survival and capture probability at Red Sands from July to November over a 6 year period (2016–2021). Abundance estimates varied year to year, ranging from 35 (95% c.i. [30, 45]) up to 233 (95% c.i. [224, 249]) M. alfredi individuals. Given the seasonal affinity of M. alfredi observed at Red Sands, this study highlights the importance of understanding fine‐scale site use within the larger home range of this population to develop local management strategies.
