Published: October 2023

Aims

The Vantage Total Ankle System is a fourth-generation low-profile fixed-bearing implant that has been available since 2016. We aimed to describe our early experience with this implant.

Methods

This is a single-centre retrospective review of patients who underwent primary total ankle arthroplasty (TAA) with a Vantage implant between November 2017 and February 2020, with a minimum of two years’ follow-up. Four surgeons contributed patients. The primary outcome was reoperation and revision rate of the Vantage implant at two years. Secondary outcomes included radiological alignment, peri-implant complications, and pre- and postoperative patient-reported outcomes.

Results

There were 168 patients (171 ankles) included with a mean follow-up of 2.81 years (2 to 4.6) and mean age of 63.0 years (SD 9.4). Of the ten ankles with implant failure (5.8%), six had loosening of the tibial component. In the remaining four failed implants, one was due to periprosthetic joint infection (PJI), one was due to loosening of the talar component, and two were due to loosening of both the tibial and talar components. Seven patients underwent reoperation: irrigation and debridement for superficial infection (n = 4); bone grafting for cysts (n = 2); and open reduction internal fixation (n = 1). Asymptomatic peri-implant lucency/subsidence occurred in 20.1% of ankles, with the majority involving the tibial component (n = 25). There were statistically significant improvements in PROMs in all domains.

Conclusion

Short-term results of this implant demonstrate early survival comparable to the reported survivorship of similar low-profile, non-stemmed implants. Radiological lucency occurred more commonly at the tibial component, and revisions occurred primarily due to loosening of the tibial component. Further research is needed to evaluate longer-term survivorship.

Authors: Walton Thomas J. , Huntley Daniel , Whitehouse Sarah L. , Davies Jennifer , Wilson Matthew J. , Hubble Matthew J. W. , Howell Jonathan R. , Kassam A. M.
Published: October 2023

Aims

The aim of this study was to perform a systematic review of the evidence for the use of intraoperative cell salvage in patients undergoing revision hip arthroplasty, and specifically to analyze the available data in order to quantify any associated reduction in the use of allogenic blood transfusion, and the volume which is used.

Methods

An electronic search of MEDLINE (PubMed), Embase, Scopus, and the Cochrane Library was completed from the date of their inception to 24 February 2022, using a search strategy and protocol created in conjunction with the PRISMA statement. Inclusion criteria were patients aged > 18 years who underwent revision hip arthroplasty when cell salvage was used. Studies in which pre-donated red blood cells were used were excluded. A meta-analysis was also performed using a random effects model with significance set at p = 0.05.

Results

Of the 283 studies which were identified, 11 were included in the systematic review, and nine in the meta-analysis. There was a significant difference (p < 0.001) in the proportion of patients requiring allogenic transfusion between groups, with an odds ratio of 0.331 (95% confidence interval (CI) 0.165 to 0.663) associated with the use of cell salvage. For a total of 561 patients undergoing revision hip arthroplasty who were treated with cell salvage, 247 (44.0%) required allogenic transfusion compared with 418 of 643 patients (65.0%) who were treated without cell salvage. For those treated with cell salvage, the mean volume of allogenic blood which was required was 1.95 units (390 ml) per patient (0.7 to 4.5 units), compared with 3.25 units (650 ml) per patient (1.2 to 7.0 units) in those treated without cell salvage. The mean difference of -1.91 units (95% CI -4.0 to 0.2) in the meta-analysis was also significant (p = 0.003).

Conclusion

We found a a significant reduction in the need for allogenic blood transfusion when cell salvage was used in patients undergoing revision hip arthroplasty, supporting its routine use in these patients. Further research is required to determine whether this effect is associated with types of revision arthroplasty of differing complexity.

Consultant revision hip arthroplasty volumes and new consultant volume trajectories in England, Wales, Northern Ireland, and the Isle of Man
Authors: Holleyman Richard J. , Jameson Simon S. , Reed Mike , Meek R. M. D. , Khanduja Vikas , Hamer Andrew , Judge Andrew , Board Tim
Published: October 2023

Aims

This study describes the variation in the annual volumes of revision hip arthroplasty (RHA) undertaken by consultant surgeons nationally, and the rate of accrual of RHA and corresponding primary hip arthroplasty (PHA) volume for new consultants entering practice.

Methods

National Joint Registry (NJR) data for England, Wales, Northern Ireland, and the Isle of Man were received for 84,816 RHAs and 818,979 PHAs recorded between April 2011 and December 2019. RHA data comprised all revision procedures, including first-time revisions of PHA and any subsequent re-revisions recorded in public and private healthcare organizations. Annual procedure volumes undertaken by the responsible consultant surgeon in the 12 months prior to every index procedure were determined. We identified a cohort of ‘new’ HA consultants who commenced practice from 2012 and describe their rate of accrual of PHA and RHA experience.

Results

The median annual consultant RHA volume, averaged across all cases, was 21 (interquartile range (IQR) 11 to 34; range 0 to 181). Of 1,695 consultants submitting RHA cases within the study period, the top 20% of surgeons by annual volume performed 74.2% of total RHA case volume. More than half of all consultants who had ever undertaken a RHA maintained an annual volume of just one or fewer RHA, however, collectively contributed less than 3% of the total RHA case volume. Consultant PHA and RHA volumes were positively correlated. Lower-volume surgeons were more likely to undertake RHA for urgent indications (such as infection) as a proportion of their practice, and to do so on weekends and public holidays.

Conclusion

The majority of RHAs were undertaken by higher-volume surgeons. There was considerable variation in RHA volumes by indication, day of the week, and between consultants nationally. The rate of accrual of RHA experience by new consultants is low, and has important implications for establishing an experienced RHA consultant workforce.

The British Orthopaedic Oncology Management (BOOM) audit
Authors: Archer James E. , Chauhan Govind S. , Dewan Varun , Osman Khabab , Thomson Calum , Nandra Rajpal S. , Ashford Robert U. , Cool Paul , Stevenson Jonathan
Published: October 2023

Aims

Most patients with advanced malignancy suffer bone metastases, which pose a significant challenge to orthopaedic services and burden to the health economy. This study aimed to assess adherence to the British Orthopaedic Oncology Society (BOOS)/British Orthopaedic Association (BOA) guidelines on patients with metastatic bone disease (MBD) in the UK.

Methods

A prospective, multicentre, national collaborative audit was designed and delivered by a trainee-led collaborative group. Data were collected over three months (1 April 2021 to 30 June 2021) for all patients presenting with MBD. A data collection tool allowed investigators at each hospital to compare practice against guidelines. Data were collated and analyzed centrally to quantify compliance from 84 hospitals in the UK for a total of 1,137 patients who were eligible for inclusion.

Results

A total of 846 patients with pelvic and appendicular MBD were analyzed, after excluding those with only spinal metastatic disease. A designated MBD lead was not present in 39% of centres (33/84). Adequate radiographs were not performed in 19% of patients (160/846), and 29% (247/846) did not have an up-to-date CT of thorax, abdomen, and pelvis to stage their disease. Compliance was low obtaining an oncological opinion (69%; 584/846) and prognosis estimations (38%; 223/846). Surgery was performed in 38% of patients (319/846), with the rates of up-to-date radiological investigations and oncology input with prognosis below the expected standard. Of the 25% (215/846) presenting with a solitary metastasis, a tertiary opinion from a MBD centre and biopsy was sought in 60% (130/215).

Conclusion

Current practice in the UK does not comply with national guidelines, especially regarding investigations prior to surgery and for patients with solitary metastases. This study highlights the need for investment and improvement in care. The recent publication of British Orthopaedic Association Standards for Trauma (BOAST) defines auditable standards to drive these improvements for this vulnerable patient group.

Cost-utility analysis of dual-antibiotic cement versus single-antibiotic cement for the treatment of displaced intracapsular hip fractures in older adults
Authors: Png May Ee , Costa Matt , Nickil Agni , Achten Juul , Peckham Nicholas , Reed Mike R.
Published: October 2023

Aims

To compare the cost-effectiveness of high-dose, dual-antibiotic cement versus single-antibiotic cement for the treatment of displaced intracapsular hip fractures in older adults.

Methods

Using data from a multicentre randomized controlled trial (World Hip Trauma Evaluation 8 (WHiTE-8)) in the UK, a within-trial economic evaluation was conducted. Resource usage was measured over 120 days post randomization, and cost-effectiveness was reported in terms of incremental cost per quality-adjusted life year (QALY), gained from the UK NHS and personal social services (PSS) perspective in the base-case analysis. Methodological uncertainty was addressed using sensitivity analysis, while decision uncertainty was handled using confidence ellipses and cost-effectiveness acceptability curves.

Results

The base-case analysis showed that high-dose, dual-antibiotic cement had a significantly higher mean cost (£224 (95% confidence interval (CI) -408 to 855)) and almost the same QALYs (0.001 (95% CI -0.002 to 0.003)) relative to single-antibiotic cement from the UK NHS and PSS perspective. The probability of the high-dose, dual-antibiotic cement being cost-effective was less than 0.3 at alternative cost-effectiveness thresholds, and its net monetary benefit was negative. This finding remained robust in the sensitivity analyses.

Conclusion

This study shows that high-dose, dual-antibiotic cement is unlikely to be cost-effective compared to single-antibiotic cement for the treatment of displaced intracapsular hip fractures in older adults.

Anterior cruciate ligament injuries in female athletes
Authors: Mancino Fabio , Gabr Ayman , Plastow Ricci , Haddad Fares S.
Published: October 2023

The anterior cruciate ligament (ACL) is frequently injured in elite athletes, with females up to eight times more likely to suffer an ACL tear than males. Biomechanical and hormonal factors have been thoroughly investigated; however, there remain unknown factors that need investigation. The mechanism of injury differs between males and females, and anatomical differences contribute significantly to the increased risk in females. Hormonal factors, both endogenous and exogenous, play a role in ACL laxity and may modify the risk of injury. However, data are still limited, and research involving oral contraceptives is potentially associated with methodological and ethical problems. Such characteristics can also influence the outcome after ACL reconstruction, with higher failure rates in females linked to a smaller diameter of the graft, especially in athletes aged < 21 years. The addition of a lateral extra-articular tenodesis can improve the outcomes after ACL reconstruction and reduce the risk of failure, and it should be routinely considered in young elite athletes. Sex-specific environmental differences can also contribute to the increased risk of injury, with more limited access to and availablility of advanced training facilities for female athletes. In addition, football kits are designed for male players, and increased attention should be focused on improving the quality of pitches, as female leagues usually play the day after male leagues. The kit, including boots, the length of studs, and the footballs themselves, should be tailored to the needs and body shapes of female athletes. Specific physiotherapy programmes and training protocols have yielded remarkable results in reducing the risk of injury, and these should be extended to school-age athletes. Finally, psychological factors should not be overlooked, with females’ greater fear of re-injury and lack of confidence in their knee compromising their return to sport after ACL injury. Both intrinsic and extrinsic factors should be recognized and addressed to optimize the training programmes which are designed to prevent injury, and improve our understanding of these injuries.

Optimizing the pathway for simple stable fractures
Authors: Fokkema Caroline B. , Janssen Loes , Roumen Rudi M. H. , van Dijk William A.
Published: October 2023

Aims

In the Netherlands, general practitioners (GPs) can request radiographs. After a radiologically diagnosed fracture, patients are immediately referred to the emergency department (ED). Since 2020, the Máxima Medical Centre has implemented a new care pathway for minor trauma patients, referring them immediately to the traumatology outpatient clinic (OC) instead of the ED. We investigated whether this altered care pathway leads to a reduction in healthcare consumption and concomitant costs.

Methods

In this retrospective cohort study, patients were included if a radiologist diagnosed a fracture on a radiograph requested by the GP from August to October 2019 (control group) or August to October 2020 (research group), on weekdays between 8.30 am and 4.00 pm. The study compared various outcomes between groups, including the length of the initial hospital visit, frequency of hospital visits and medical procedures, extent of imaging, and healthcare expenses.

Results

A total of 634 patients were included. The results show a median reduction of 25 minutes in duration of initial hospital visits, one fewer hospital visit, overall fewer medical procedures, and a decrease in healthcare costs of €303.40 per patient in the research group compared to the control group. No difference was found in the amount of imaging.

Conclusion

The implementation of the new care pathway has resulted in a substantial reduction in healthcare use and costs. Moreover, the pathway provides advantages for patients and helps prevent crowding at the ED. Hence, we recommend immediately referring all minor trauma patients to the traumatology OC instead of the ED.

Abstract. Haslianti, Sahidin, Asnani, Fristiohady A. 2023. Growth, biomass, and carotenoids content analysis of Navicula sp. and Chlorella sp. in batch cultures with different salinities. Biodiversitas 24: 4299-4306. The physiological activity of microalgae is strongly influenced by culture conditions. Therefore, the rebound in this microscopic plant blooming phenomenon varies according to the aquatic environmental parameters, especially the salinity of its medium. This study aimed to analyze the cell density, biomass, and carotenoid content of two types of microalgal cultures isolated from the sea of Southeast Sulawesi. This research was conducted from October 2021 to October 2022. The independent variable in this study was salinity (30, 33, and 36‰), and the dependent variables were the parameters of cell density, biomass, and carotenoids content. This study consisted of 135 unit experiments using a completely randomized design (CRD). The same trend in cell density is observed in the two types of microalgae, where exponential growth occurred from day 2 to day 6 and decreased in growth rate on day 7. The biomass content of the two types observed was relatively the same, ranging from 0.0176-0.0181 g, while the carotenoids content ranged from 12.8294-25.5958 g/mL. The highest carotenoids level was found in the type of Chlorella sp. (25.5958 g/mL) while the lowest was in the type of Navicula sp. (12.8294 g/mL). The data indicate that the salinity parameter (>30?36‰) greatly influences and thus spikes growth in cells due to their biomass and high carotenoid content. The environment parameter also contributes significantly to other physiological parameters (one-way ANOVA, p<0.05).

Abstract. Nurrochmat NA, Purnomo H, Muhdin, Erbaugh JT. 2023. Developing sustainable models of agroforest-landscape in Bogor, Indonesia. Biodiversitas 24: 4324-4333. Deforestation continues in Indonesia even though many regulations and precautions have been taken. It most likely happened due to the less economic contribution from the forestry sector, which caused the conversion from forest lands to more profitable land uses. The forest area covers 125 million hectares (66%) of 190 million hectares of country land but contributes only about 0.60% of the Gross Domestic Product (GDP). An agroforestry scheme is promoted to increase the economic value of the forest to increase both the community welfare and the environmental quality. This study indicates that the best agroforestry commodities for social scenarios are durian, ornamental plants, and laying hens, with the highest potential profit of IDR.143,857,559 (USD.9,652)/hectare/month and 9.19 tons/hectare carbon stock. While for the economic scenario is jackfruit, ornamental plants, and laying hens with a potential profit of IDR.146,908,379 (USD.9,789)/hectare/month and 18.66 tons/hectare carbon stock. In comparison, the ecology scenario promotes nutmeg and ornamental plants with a potential profit of IDR 36,814,280 (USD.2,470)/hectare/month, with the highest of 56.12 tons/hectare carbon stock. This study recommends the appropriate land use models for the government to address the conflict of interest between agriculture and forestry in contributing to Indonesia's FoLU (Forestry and other Land Uses) Net Sink in 2030.

Abstract. Sjahriani T, Kurniati M, Arivo D, Syukri DM, Tyasningsih W. 2023. Genetic development of Stx phage. Biodiversitas 24: 4334-4341. Stx phages have been studied and described due to their involvement in shigatoxin. The variety, evolution, dispersion, and molecular mechanisms of STEC and Stx phages have all been widely studied, but the further research is still required. The objective of this study was to investigate the unique sequences of bacteriophage DNA from the NCBI database and to identify the changes in the DNA sequence of both regular and stx-carrying bacteriophages. It was first reported in 2001, but studies have not been carried out. The stx-carrying bacteriophage DNA sequence, similarity of identity, e-value, and gaps were analyzed using PCR and DNA sequencing. The number of bacteriophage that used in this study was eight. The results revealed the similarity of bacteriophage to stx-carrying bacteriophages by 82.67% to 88.5%, and exhibited notable variations in comparison to each phage 1 to 8 (Eco157 phage WASJ/2022) (p<0.001). Moreover, results exhibited an e-value ranging from 7e-85 to 3e-44. In addition, results showed gaps between 1-2% in comparison to other stx-carrying bacteriophages in NCBI with bacteriophage alterations on the bases of Cytosine and Thymine in 184th and 263rd. Therefore, this work provided the potency of bacteriophage as an alternative pharmaceuticals in controlling foodborne diseases.

The current state of the cenopopulations of Adonis tianschanica (Adolf) Lipsch. (Ranunculaceae) in Southeast Kazakhstan. Biodiversitas 24: 4359-4372. Adonis tianschanica (Adolf) Lipsch. is a rare, sub-endemic species growing in the Tien Shan mountains with declining numbers, making it listed in the Red Book of Kazakhstan. The aim of the study is to investigate the distribution and abundance of A. tianschanica cenopopopulations (CP) in its natural habitats in southeastern Kazakhstan as well as assess soil characteristics, biological and arealogical features, including the ontogenetic structure of cenopopopulations. Five cenopopulations (CP) of A. tianschanica were identified, namely two CPs in Ketmen Ridge (Kegen Pass), two CPs in Dzungarian Alatau (Tekeli Gorge) and one CP in Terskey Alatau (Saryzhaz). Vegetation data were collected using the traditional methods of field geobotanical studies based on the ecological-physiognomic approach.Plant communities having dominant species from a single ecobiomorph and ecologically related species groups.We complemented the population analysis with a soil properties map compiled from existing cartographic and available literature. The results of this study indicated the low number of A. tianschanica individuals in all CPs, which is likely due to the biological characteristics of the species (i.e. low seed production and seedling recruitment and the lack of vegetative regeneration) as well as environmental factors, and anthropogenic impact, mainly grazing with. We found that the total number of individuals of A. tianschanica in the five cenopopulations was 106 individuals. The average density of the species varied from 1.3 to 3.1 plants/m2 with CP2 being the highest and CP5 the lowest. The five cenopopulations were classified based on the absolute maxima of ontogenetic groups. There were two maxima in the age composition of individuals in CPs 3 and 4: the first (18.8-42.1%) was a group of vegetative plants (v), and the second (21.1-50.0%) was a group of young generative plants (g1). The natural state of the habitat of this cenopopulation can be explained as more favorable than others. In CP2, the absolute maximum corresponded to vegetative plants group (v) (37.0%). In CP5, young generative individuals (g1) and mature generative (g2) predominated (from 30.8% to 38.4%). In terms of age composition, the state of A. tianschanica cenopopulations is considered relatively satisfactory but demonstrated a low level of abundance. It has been established that the state of the species populations in the studied regions is affected by soil conditions, changes in climatic conditions and anthropogenic impact.

Abstract. Bon SG, Antesco GP, Enicola EE. 2023. Morphological characteristics and variability of traditional starch forming coix (Coix lacryma-jobi var. ma-yuen populations from Mindanao Island, Philippines. Biodiversitas 24: 4382-4391. Adlay (Coix lacryma-jobi var. ma-yuen (Rom.Caill.) Stapf) is an underutilized crop in the Philippines with high potential. Characterization and elucidation of the available variability among the local adlay populations are essential information for its improvement and better utilization. The study aimed to characterize the qualitative morphological traits of 34 traditional adlay populations from Mindanao Provinces and assess diversity by the Shannon Index and similarity by multivariate clustering. Results showed that all populations shared the same morphotypes in five descriptors but were variable for the rest. Six populations showed intense leaf anthocyanin coloration, and 23 expressed upright growth habits. Three types of leaf blade colors were observed, while the intensity of anthocyanin coloration of culms was expressed in four types. Most populations had semi-pubescent or highly pubescent leaves, generally intermediate leaf orientation and non-glaucous leaves. Immature grains were generally light green but expressed four color types at maturity, mostly circular with furrows on the surface. Diversity Indices (H') ranged from low to high. Leaf blade pubescence, anthocyanin coloration of culm, and mature grain color had high H' values. Cluster analysis showed that the variability was narrow, where overall clustering achieved 0.50 similarity. At 0.65 similarity, three groups can be derived with three populations as outliers. Clustering can be attributed to the differences in seedling color, anthocyanin coloration, plant growth habit, immature grain color, mature grain color, and shape. The study established the morphological description of the qualitative traits of traditional Philippine adlay and assessed diversity to be generally intermediate, where populations can be clustered into subgroups according to the degree of morphotype similarities. Clustering, however, was not related to provenances. It is recommended to conduct further geographic germplasm sampling, marker-based characterization, and agronomic evaluation to dissect further the genetic diversity and crop potential of the local adlay populations.

Checklist of the earthworm fauna of Uzbekistan (Oligochaeta: Lumbricidae). Biodiversitas 24: 4392-4401. This article presents a checklist of the earthworm fauna (Lumbricidae) of Uzbekistan based on published records and the authors' data. This is the first checklist for Uzbekistan, which contains complete information on the ecological category, habitat, type of distribution and distribution of 28 species of earthworms in 4 regions of Uzbekistan. The currently known, based on our research, earthworm fauna of Uzbekistan, includes 23 species, 5 subspecies belonging to 9 genera. Of them, 3 species (Perelia persiana, Perelia turcmenica, Lumbricus rubellus) are new to Uzbekistan. Perelia is the species-richest genus (12 species). These earthworms are distributed Kyzylkum desert region along river banks, in the mountainous regions of Pomiro Alai and Tien Shan biogeographic region, which is mostly covered with forest or autochthonous flora. The earthworm fauna is more diverse in forests of the northern and in the mountains of the southern parts of Uzbekistan. Literature data and our present study showed that there are no earthworms in the Ustyurt Plateau, due to the fact that the soils of the Ustyurt Plateau are gypsum, saline, and infertile.

Abstract. Lantang B, Najamuddin, Nelwan AFP, Samawi MF. 2023. Density distribution of Penaeus merguensis De Man, 1888 based on habitat in the waters of Merauke District, South Papua Province, Indonesia. Biodiversitas 24: 4427-4437. The waters of Merauke District, located in the Arafura Sea area, have relatively hight penaeid resource, but prawn fishing productivity is the lowest of 11th other Indonesian fisheries management areas.. The optimization of the fishery resource utilization remains poor after the moratorium on fishing vessel licensing in 2014, which is only 11%. Hence, a study is needed to determine the resources’ distribution, abundance, and sustainability. This research aims to analyze the density distribution of banana prawn (Penaeus merguensis De Man, 1888) based on the habitat type, each location separated by ~4-5 kilometers within the coastal ecosystem waters of Merauke District. The research was carried out from March to August 2022. Data were collected within each habitat: the catch, prawn fishing equipment, and oceanographic parameters, and then analyses were undertaken using statistical tests. The results showed that the highest density of banana prawn was obtained in shallow waters adjacent to the mangrove habitat at Bokem (32.68 kg/km2) and Yobar (20.27 kg/km2). In waters adjacent to the sandy beach at Payum (17.98 kg/km2), the density was higher than within the estuarine habitat of Maro River (14.60 kg/km2) and adjacent to the sandy beach at Lampu Satu (14.39 kg/km2). This is due to the influx of fresh water in estuarial habitat, sandy beaches in Lampu Satu and Payum, and mangroves in Yobar, resulting in prawn emigration to areas with higher salinity in Bokem mangroves. It is also thought to be associated with increasing turbidity with a similar pattern in salinity and affecting the density of banana prawns.

Abstract. Mascari?as HJC, Otadoy JB. 2023. Economic valuation of seagrass ecosystem in Maribojoc Bay, Bohol, Philippines. Biodiversitas 24: 4427-4435. The seagrass ecosystem is one of the most productive and precious ecosystems. In the Philippines, however, more data on the economic valuation of all seagrass ecosystem services must be collected. The study estimated the total economic value of the seagrass ecosystem, including use and non-use values. Resource user groups include municipal ?shers, gleaners, and tourism business operators. The sample size was determined based on the total number of resource users in Maribojoc Bay, Bohol, Philippines and using a confidence coefficient of 95% (P = 0.05). The total economic value of the seagrass ecosystem in Maribojoc Bay is PhP 52.8 million (US$ 1.1 million). Direct use values, or market benefits, are PhP 35.4 million (US$ 708 thousand), accounting for 67% of the total economic value. Indirect and non-use values, are PhP 17.3 million (US$ 346 thousand), accounting for 33% of the total economic value. On a per hectare basis, the economic value of the seagrass ecosystem in Maribojoc Bay is PhP 46,722 (US$ 934). The results of this valuation can be an input in decision-making to manage and conserve the seagrass ecosystem as well as maintain the economic security of Maribojoc Bay. The findings of this study are valuable for developing a comprehensive information management and decision-support system for the management and protection of the seagrass ecosystem. However, more research is required to evaluate the range of ecosystem services provided by seagrass ecosystems across the country, focusing on qualitative value attributions linked to the social-ecological dynamics of seagrass systems.

Abstract. Azzahra PR, Sumarga E, Sholihah A. 2023. Mangrove ecotourism development at Karimunjawa National Park, Indonesia. Biodiversitas 24: 4457-4468. Karimunjawa National Park (KJNP) is a marine conservation area with a high potential for developing mangrove ecotourism in Indonesia. Several essential aspects should be adequately understood to support mangrove ecotourism in KJNP, including the potential of tourism attractions, the ecological carrying capacity for tourism, the potential support from stakeholders, and the best strategies based on the latest conditions. This study aimed to (i) identify and analyze the potential of mangrove ecotourism attractions in KJNP, (ii) analyze the carrying capacity for mangrove ecotourism, (iii) analyze the level of influence and interest of stakeholders, and (iv) determine strategies for developing mangrove ecotourism in KJNP. The ecotourism attraction potentials were analyzed using a modified version of the assessment of Natural Tourism Attraction Objects (NTAO) (Objek Daya Tarik Wisata Alam – ODTWA). The carrying capacity was analyzed using the Area Carrying Capacity concept. The influence and interest level of stakeholders were analyzed using the economic characteristics of the community and the stakeholder grids. The strategy for developing mangrove ecotourism was determined using Strength, Weakness, Opportunity, Threat (SWOT), and Quantitative Strategic Planning Matrix (QSPM) analyses. The results showed that mangrove ecotourism in KJNP is highly potential and feasible to be developed based on the assessment of 15 criteria of NTAO with a carrying capacity of ca. 104 visitors/day. About 96% of the community agrees to support the development of mangrove ecotourism in KJNP. Karimunjawa National Park Office and the local community were identified as essential players from the eight recognizable stakeholders. Seven main strategies were formulated for developing mangrove ecotourism in KJNP, with the improvement of cooperation among stakeholders in developing facilities and tourist attractions and promoting mangrove ecotourism was perceived as the most urgent strategy to be implemented.

Abstract. Rozaini AF, Laurie KH, Marshall DJ. 2023. Population and spatial ecology of horseshoe crabs (Limulidae) in a nursery ground at Pulau Bedukang, Brunei Bay, Borneo. Biodiversitas 24: 4485-4492. Suitable nursery habitat to support populations of juvenile horseshoe crabs is becoming threatened globally. There are currently no formal studies on juvenile populations of the horseshoe crabs (Limulidae) for Brunei Darussalam (Brunei, Borneo). We investigated body size structure, population cohort and ecological distribution of juvenile horseshoe crabs associated with a mudflat on Pulau Bedukang, in Brunei Bay. Seventy juveniles were retrieved during four sampling days covering two seasons and four study sites. Carcinoscorpius rotundicauda and Tachypleus gigas were common, whereas only two individuals of Tachypleus tridentatus were found. Carapace width (size) was similar in the common species and there was no difference in juvenile size between the seasons and study sites. Body weight to carapace width relationships showed that the species grew at similar rates, although C. rotundicauda developed faster, producing 14 compared to the eight pre-migration mudflat instars produced by T. gigas. Species densities were similar, and there was no spatial separation of species or juvenile size across the mudflat or in relation to the mangrove forest edge. Nearest-neighbor (NN) analysis showed that individual crabs were generally dispersed. Their mudflat cohabitation suggests physiological and behavioral plesiomorphies for common optimal developmental salinity and temperature conditions. This study provides baseline information for comparison with other regional studies and for local conservation planning.

Abstract. Lindiani P, Sundawati L, Suwarna U. 2023. Effect of biophysical conditions on standing and soil carbon storage in various land uses in Gunung Mas, Central Kalimantan, Indonesia. Biodiversitas 24: 4493-4502. One of the human activities that accelerates climate change is degradation and deforestation, which can lead to new land use in the form of palm oil plantations and agroforestry. Both of these land uses have the potential to store carbon, which can be optimized if the influencing factors are known. This study aims to estimate the potential for carbon storage in palm oil and agroforestry plantations in Gunung Mas, Central Kalimantan, Indonesia, and to analyze the effect of biophysical conditions such as topography, soil fertility, and stand density on the potential for carbon storage. The research was conducted in palm oil plantations (POP) and agroforestry areas categorized as agroforestry with forestry and palm oil plantation commodities (AG-SS), as well as agroforestry consisting of forestry, palm oil, and fruit crops (AG-SSB). Sample plots were determined through purposive sampling with 30 plots for each land use. The research results show significant differences in aboveground carbon (AGC), soil organic carbon (SOC), and total carbon storage among the three land uses. The largest total AGC was in AG-SS (66.24 ton.ha-1), while the lowest AGC was observed in POP (48.15 ton.ha-1). The greatest SOC was recorded in AG-SSB (2163.21 ton. ha-1), followed by POP (1922.12 ton.ha-1) and AG-SS (1846.72 ton.ha-1). The highest total carbon storage was measured in AG-SSB (2223.36 ton.ha-1), followed by POP (1970.27 ton.ha-1), and the lowest in AG-SS (1912.96 ton.ha-1). Biophysical factors, including topography, soil fertility, and stand density, influenced carbon storage in each land use. Topography and stand density factors significantly influenced AGC, while soil fertility factors significantly affected SOC and total carbon storage in all three land uses.

No abstract available. Article truncated after 150 words. History of Present Illness: A 75-year-old man presented from a skilled nursing facility with altered mental status and hypotension. He had a seven-year-long history of steroid-dependent myasthenia gravis, but had previously declined Covid vaccination, and subsequently experienced a severe case of COVID-19 pneumonia five months prior to admission. This resulted in chronic respiratory failure and renal failure for which he subsequently underwent tracheostomy, tunneled subclavian vein dialysis catheter placement and percutaneous endoscopic gastrostomy (PEG). He had resided in a skilled nursing facility since then, requiring four subsequent hospital readmissions for complications. These sequentially included septic shock due to a catheter associated blood stream infection, an intra-abdominal abscess due to PEG migration into the peritoneum resulting in fungal blood stream infection, recurrent intra-abdominal infection with multiple organisms, and bacterial pneumonia. Treatment of these infectious complications included replacement of the tunneled dialysis catheter and exploratory laparotomy with debridement of multiple abscesses. The …

The objective of this work was to evaluate gas exchanges in umbu tree accessions. A 5 × 7 × 2 split-split plot experiment was carried out in a completely randomized design (five accessions – BRS-68, EPAMIG-05, BGU-61, BGU-75, and BGU-50 × seven evaluation dates × two reading times – 8 a.m. and 2 p.m.) with three repetitions. The lower leaf temperatures recorded in BRS-68 and EPAMIG 05 accessions favor higher net photosynthetic rates, water use efficiency and instantaneous carboxylation efficiency compared to BGU 61 accession. Umbu tree regulates transpiration by reducing stomatal conductance under high vapor pressure deficit, although the tree increases transpiration as a defense strategy against heat stress, even with a reduction in stomatal conductance. High temperatures limit instantaneous carboxylation efficiency, photosynthetic rate, and the ratio of photosynthesis to radiation incident on the leaf. Transpiration varies directly with stomatal conductance, while intrinsic water use efficiency varies inversely with internal CO2 concentration.

The blue economy covers various scientific areas and types of socio-economic activity that are related to each other: fisheries, shipping, tourism (beach and cruise), transportation, logistics, alternative energy, ecology, water management, climate change and biosphere conservation. It was found that coastal tourism occupies an important place in the system of the Blue Economy. According to the set of indicators: The Travel and Tourism Competitiveness Index, International tourist arrivals, thousands, Travel and Tourism industry GDP, and Employment in the tourism and travel sphere, a cluster analysis has been created for leading countries. As a result of the analysis, 9 clusters have been formed, for each of which strategic vectors of development were determined. The coastline of all countries in the world is 1162.3 million km. The longest coastline belongs to Canada – 202080 km. Relative indicators per 1 km of coastline as international tourist arrivals, international tourism inbound receipts, Tourism and Travel industry GDP have been considered. It has been substantiated that the Spanish coastal tourism industry deserves special attention. There are 17 coastal areas and more than 2,000 beaches in Spain.

Published: October 2023

The study aims to examine the views of local executives and managers in Thessaly, Greece related to the potential profitability of investing in the health tourism industry. Furthermore, the study attempts to shed some light on the factors that affect their views about health tourism investments. The data are collected through self-administered questionnaires to stakeholders in facilities that have the potential, or they are already, engaged in the health tourism industry. The sample is collected from a wide range of facilities, namely hotels, hospitals, private clinics, rehabilitation centres and nursing homes. Kendall’s tau-b correlation statistics and logistic regression models are employed to detect the driving forces on the formation of attitudes towards health tourism investments. Current research regarding health tourism in Greece is rather limited. In addition, the majority of relevant international studies examines factors shaping the demand side. The present study utilizes a sample from the supply side, thus of stakeholders in related sectors and can enhance our knowledge about their stances towards health tourism investments and the factors shaping these stances.
