Modeling Habitat Suitability of Snow Leopards in Yanchiwan National Reserve, China.

Snow leopards (Panthera uncia) are elusive predators inhabiting high-altitude and mountainous rugged habitats. The current study was conducted in the Yanchiwan National Nature Reserve, Gansu Province, China, to assess the habitat suitability of snow leopards and identify key environmental factors inducing their distribution. Field data collected between 2019 and 2022 through scat sampling and camera trapping techniques provided insights into snow leopard habitat preferences. Spatial distribution and cluster analyses show distinct hotspots of high habitat suitability, mostly concentrated near mountainous landscapes. While altitude remains a critical determinant, with places above 3300 m showing increased habitat suitability, other factors such as soil type, human footprint, forest cover, prey availability, and human disturbance also play important roles. These variables influence ecological dynamics and are required to assess and manage snow leopard habitats. The MaxEnt model has helped us to better grasp these issues, particularly the enormous impact of human activities on habitat suitability. The current study highlights the importance of altitude in determining snow leopard habitat preferences and distribution patterns in the reserve. Furthermore, the study underscores the significance of considering elevation in conservation planning and management strategies for snow leopards, particularly in mountainous regions. By combining complete environmental data with innovative modeling tools, this study not only improves local conservation efforts but also serves as a model for similar wildlife conservation initiatives around the world. By understanding the environmental factors driving snow leopard distribution, conservation efforts can be more efficiently directed to ensure the long-term survival of this endangered species. This study provides valuable insights for evidence-based conservation efforts to safeguard the habitats of snow leopards amidst emerging anthropogenic pressure and environmental fluctuations.

Accelerating Glacier Area Loss Across the Andes Since the Little Ice Age

AbstractAndean glaciers are losing mass rapidly but a centennial‐scale context to those rates is lacking. Here we show the extent of >5,500 glaciers during the Little Ice Age chronozone (LIA; c. 1,400 to c. 1,850) and compute an overall area change of −25% from then to year 2000 at an average rate of −36.5 km2 yr−1 or −0.11% yr−1. Glaciers in the Tropical Andes (Peru, Bolivia) have depleted the most; median −56% of LIA area, and the fastest; median −0.16% yr−1. Up to 10 × acceleration in glacier area loss has occurred in Tropical mountain sub‐regions comparing LIA to 2,000 rates to post‐2000 rates. Regional climate controls inter‐regional variability, whereas local factors affect intra‐region glacier response time. Analyzing glacier area change by river basins and by protected areas leads us to suggest that conservation and environmental management strategies should be re‐visited as proglacial areas expand.

Pain, Function and Trunk/Hip Flexibility Changes Immediately after Clinical Pilates Exercises in Young Adults with Mild Chronic Low Back Pain

Background: Pilates is among the best conservative management strategies for chronic low back pain. However, several variations of Pilates exist. This study aimed to investigate physical measures that would detect immediate changes after a brief session of Clinical Pilates exercises. Changes in self-reported clinical outcomes, pain and function were also evaluated. Methods: A prospective cohort study was conducted. Eighteen young adults with chronic low back pain participated in this study. Participants were assessed for pain and function subjectively, and hip/knee strength and trunk/hip flexibility objectively, followed by a session of Clinical Pilates assessment and exercises. After the exercises, the participants were immediately reassessed for pain, function, strength, and flexibility. Results: Trunk/hip flexibility showed statistically significant changes after exercise, which were measured with the sit-and-reach test (−3.44 cm, 95% CI [−5.10, −1.79], p < 0.001) and the finger-to-floor test (−6.29 cm [−9.51, −3.06], p = 0.001). Statistical significance was not found in detecting strength changes in hip extension, hip abduction, and knee extension. Changes in pain (1.56 points [0.83, 2.28], p < 0.001) and patient-specific functional scale (−1.52 points [−1.93, −1.10], p < 0.001) were also found after exercise. Conclusions: Trunk/hip flexibility measures detected physical changes after Clinical Pilates exercise, as well as self-reported pain and function outcomes, without reducing strength performance.

Fungal Saprotrophic Promotion and Plant Pathogenic Suppression under Ditch-Buried Straw Return with Appropriate Burial Amount and Depth.

Fungi as heterotrophs are key participants in the decomposition of organic materials and the transformation of nutrients in agroecosystems. Ditch-buried straw return as a novel conservation management strategy can improve soil fertility and alter hydrothermal processes. However, how ditch-buried straw return strategies affect the soil fungal community is still unclear. Herein, a 7-year field trial was conducted to test the influences of burial depth (0, 10, 20, 30, and 40 cm) and the amount of ditch-buried straw (half, full, double) on the diversity, composition, and predicted functions of a soil fungal community, as well as the activities of carbon-degraded enzymes. Under the full amount of straw burial, the abundance of phylum Ascomycota was 7.5% higher as compared to other burial amount treatments. This further increased the activity of cellobiohydrolase by 32%, as revealed by the positive correlation between Ascomycota and cellobiohydrolase. With deeper straw burial, however, the abundance of Ascomycota and β-D-glucopyranoside activity decreased. Moreover, genus Alternaria and Fusarium increased while Mortierella decreased with straw burial amount and depth. FUNgild prediction showed that plant fungal pathogens were 1- to 2-fold higher, whilst arbuscular mycorrhizal fungi were 64% lower under straw buried with double the amount and at a depth of 40 cm. Collectively, these findings suggest that ditch-buried straw return with a full amount and buried at a depth less than 30 cm could improve soil nutrient cycles and health and may be beneficial to subsequent crop production.

Fast-track knee pathway: A cost effective, quality improvement initiative for knee osteoarthritis

BACKGROUND: The prevalence of knee osteoarthritis is increasing due to population growth, ageing and other risk factors. However, the majority of patients can successfully manage their symptoms using conservative management strategies with only a minority requiring surgery. In 2019, a patient waited four years to be seen if deemed routine for an elective orthopaedic out-patient appointment in a large acute hospital in Ireland. OBJECTIVE: To establish a Fast-Track Knee Pathway in an Irish healthcare setting, creating a more efficient channel into elective orthopaedics for patients requiring surgical intervention whilst providing community-based care for those with non-surgical needs. METHODS: a) Establishment of a dedicated community-based physiotherapy and dietetic service for knee osteoarthritis, b) implementation of a Rapid Access Knee Clinic in elective orthopaedic clinics, and c) economic evaluation of the Fast-Track Knee Pathway’s cost effectiveness compared with the traditional pathway. RESULTS: 403 patients with knee osteoarthritis were removed from physiotherapy waiting lists with 9 patients requiring referral onwards to the Rapid Access Knee Clinic. On average there was a 64% reduction in wait time to access an orthopaedic consultant across 4 pilot sites. An incremental cost-effectiveness ratio of € 22,535.03 per QALY was estimated. Comparing this to the national accepted threshold of € 45,000 per QALY the Fast-Track Knee Pathway can be considered cost-effective. CONCLUSION: The Fast-Track Knee Pathway provides a fully integrated pathway of care for patients with knee osteoarthritis, facilitating earlier access to orthopaedic intervention. An economic evaluation concluded that this model of care is more cost-effective than the traditional pathway.

Predicting the Potential Distribution of Hypericum perforatum under Climate Change Scenarios Using a Maximum Entropy Model.

H. perforatum, as one of the Traditional Chinese Medicinal materials, possesses a variety of pharmacological activities and high medicinal value. However, in recent years, the wild resources of H. perforatum have been severely depleted due to global climate change and human activities, and artificial cultivation faces problems such as unstable yield and active ingredient content. This poses a serious obstacle to the development and utilization of its resources. Therefore, this experiment took H. perforatum as the research object and used 894 distribution records of H. perforatum and 36 climatic environmental factors, using the MaxEnt model and GIS technology to explore the main climatic factors affecting the distribution of H. perforatum. Additionally, by utilizing the principles of ecological niche theory, the potential suitable distribution regions of H. perforatum across past, present, and future timelines were predicted, which can ascertain the dynamics of its spatial distribution patterns and the trend of centroid migration. The results indicate that the main environmental factors affecting the geographical distribution of H. perforatum are solar radiation in April (Srad4), solar radiation in September (Srad9), mean temperature of driest quarter (Bio9), solar radiation in November (Srad11), annual mean temperature (Bio1), and annual precipitation (Bio12). Under future climate scenarios, there is a remarkable trend of expansion in the suitable distribution areas of H. perforatum. The centroid migration indicates a trend of migration towards the northwest direction and high-altitude areas. These results can provide a scientific basis for formulating conservation and sustainable use management strategies for H. perforatum resources.

The Role of Secondary Conservative Management Strategies in Bladder and Bowel Dysfunction: A Systematic Review and Meta-analysis

We sought to determine the effect of secondary management strategies in addition to urotherapy on bowel bladder dysfunction outcomes. The review protocol was prospectively registered (CRD42023422168). MEDLINE, Embase, Cochrane Central Register of Controlled Trials, CINAHL, and Scopus (database initiation until June 2023) were searched. Comparative studies of secondary management strategies vs conventional urotherapy alone were included. Two authors independently screened titles, abstracts, and reviewed full-text articles. Two authors extracted data related to study characteristics, methodology, subjects, and results. In this systematic review and meta-analysis of 18 studies and 1228 children, secondary management strategies (home-based education, biofeedback, and physical therapy) were associated with reduced symptom burden, fewer recurrent urinary tract infections, and improved uroflowmetry findings than children treated solely with urotherapy for conservative management. Although there is significant reporting heterogeneity, secondary conservative management strategies such as home education, biofeedback or cognitive behavioral therapy, and physiotherapy-based education are associated with less urinary incontinence, fewer infections, and fewer abnormal uroflowmetry findings.

Spatial and seasonal variations in the growth of the populations of tongue sole fish (Cynoglossus quadrilineatus Bleeker, 1851) along four different stations of Makran coast by using the von Bertalanffy model

BackgroundGrowth is a most important life-history trait that defines the maximum size and age, maturation stage, and mortality of any fish species and is also involved in stock assessment models commonly used in fisheries conservation or management. ObjectivesThe present study focused on assessing the growth patterns and related parameters to the population of tongue sole (Cynoglossus quadrilineatus) along different sites of the Makran coast in temperate regions. MethodologyA total of 987 tongue sole fishes were collected seasonally from four different sites along the Makran coast (Gwadar, Pasni, Ormara, and Sur Bandar). Growth parameters i.e., length-weight relationships, length-frequency distribution, von Bertalanffy (VBGF) growth model, and stock status were analyzed. ResultsThe overall results of the length-weight relationship (LWRs) of this species showed only a significantly positive allometric growth pattern (b < 3.0; p < 0.05) observed during three seasons along the four selected sites of Makran Coast. The estimated von Bertalanffy (VBGF) growth parameters of C. quadrilineatus at four stations were described as; maximum observed length (Lmax) = 31.65 cm, asymptotic length (L∞) = 33.32 cm, size at sexual maturity (Lm) = 17.98 cm, Lopt = 20.55 cm, growth coefficient per year (k) = 0.55 year -1, t0 = 0.04 year -1, f = 2.79, Tmax = 2.80 years, tm = 0.78 year, M = 1.64 per year, topt = 1.30 years. The present study also noted seasonal variations in the length frequency distribution (LFD) data between the four selected sites. ConclusionsThus, our study concluded that the von Bertalanffy growth model (VBGF) is the best-fitted model for analyzing the growth patterns of C. quadrilineatus at different sites and during various seasons along the Makran Coast. This model demonstrated superior predictive ability and effectively described changes in growth patterns or body size across sub-populations of C. quadrilineatus at the four study sites. Thus, our research provides valuable insights into the population dynamics and life history traits of this tongue sole population in the Makran coast. Moreover, as the first study on the growth of this species, our findings offer essential information for informing sustainable exploitation, conservation, and fishery management strategies.

Genetic assessment of eight zoo populations of golden snub-nosed monkey (Rhinopithecus roxellana) implication to the conservation management of captive populations.

Captive breeding programs play an important role in preserving the genetic diversity of endangered species. It is of utmost importance to conduct genetic assessment for captive populations in order to develop scientific breeding plans and conservation management strategies. Here, we genotyped 10 microsatellite loci and sequenced 368 bp of mitochondrial DNA control region for the golden snub-nosed monkey (Rhinopithecus roxellana) from eight captive populations in China, and compared the genetic indices of captive populations with a wild population. Meanwhile, we performed paternity tests to verify the genealogical records and established genetic lineages. A total of 157 individuals were identified from 161 fecal samples, including 135 captive individuals (approximately 25% of captive individuals in China). Microsatellite analysis showed that the nine populations had moderate levels of genetic diversity, with polymorphism information content (PIC) ranging from 0.43 to 0.542; the genetic diversity of captive populations (average PIC: 0.503) was slightly higher than that of the wild population (PIC: 0.438). The Structure analysis indicated that individuals of the eight captive populations contained two different genetic components. We conducted either single-blind or double-blind paternity testing on 40 offspring of captive individuals and found that five offspring from two zoos (Nanjing Hongshan Forest Zoo and Shanghai Wild Animal Park) showed discrepant kinships from their pedigree records, probably due to the inaccuracies in pedigree records. By constructing genetic pedigrees, inbred offspring were found in Beijing Zoo, Shanghai Zoo, Hangzhou Zoo, and Chengdu Zoo. Analysis based on mitochondrial DNA showed a high level of genetic diversity in the eight captive populations (mean nucleotide diversity: 0.047). However, no nucleotide diversity was found in the wild population. This study conducted a genetic survey for captive golden snub-nosed monkeys and will significantly benefit the genetic conservation management for captive populations in the future.

Patterns in the global diversity of mixed‐species bird flocks in relation to environmental factors

AbstractPreserving biodiversity requires an understanding of how natural environments and anthropogenic factors shape the global distribution of biological diversity. Moving beyond a focus on endangered species, conservation needs to also preserve the typical interactions among species that structure communities, such as those found in mixed‐species bird flocks (MSBFs). The objective of this study is to quantify the α and β diversity of MSBFs on a global scale and explore the influence of environmental factors. Based on data compiled from 172 global publications encompassing 2095 MSBF participating bird species, we investigated the distribution patterns and influencing factors of MSBFs at different latitudes globally. The findings revealed that the species diversity of MSBFs is higher at lower latitudes. In terms of β diversity, MSBFs exhibit high‐turnover at mid to low latitudes and nested patterns at higher latitudes. Environmental factors positively influencing α and β species diversity of MSBFs included temperature and solar radiation, while wind speed and human disturbance negatively affected diversity. Based on the wide distribution and conservation significance of MSBFs, we provide quantifiable data on their global diversity patterns and suggest that future animal conservation management strategies should prioritize a community‐based approach focused on interspecific interactions.

Management of osteonecrosis of the humeral head in the pediatric population: A systematic review.

Humeral head osteonecrosis in the pediatric patients most often occurs in patients with underlying hemoglobinopathies, exposure to chronic corticosteroids, or after trauma. The purpose of this study was to perform a systematic review evaluating the prevalence, clinical characteristics, and management of humeral head osteonecrosis in the pediatric population. PubMed, Ovid MEDLINE, and Scopus were screened with the terms "osteonecrosis," "avascular necrosis," "pediatric," and "proximal humerus" on January 10, 2024. A total of 218 studies were screened, and 74 studies were evaluated for eligibility. Studies that reported on the prevalence and/or management of pediatric humeral head osteonecrosis were included. The systematic review was conducted according to the Preferred Reporting Items for Systematic Review and Meta-Analyses guidelines. Twelve studies met inclusion criteria: four retrospective case series, three prospective case series, one retrospective cohort study, one retrospective case-control study, and three case reports. A majority of the studies (67%) discussed chemotherapy-induced osteonecrosis of the humeral head. A total of 77 patients (106 shoulders) with humeral head osteonecrosis were identified. The overall prevalence of osteonecrosis of the humeral head across eight studies examining at-risk populations (underlying hemoglobinopathies or undergoing chemotherapy) was 2%. Intra-articular steroid injections, physical therapy, and activity modification are effective conservative management strategies. Additionally, core decompression and hemiarthroplasty are surgical treatment options. The prevalence of osteonecrosis of the humeral head is low even among at-risk populations with associated medical conditions. A variety of conservative and surgical treatment options have been described, but no comparative evaluations of these modalities has been conducted. IV.

Assessing the environmental factors affecting the sustainability of Aini Falaj system.

This study investigates the spatial distribution patterns and environmental factors influencing the Aini Falaj system in a specific study area. The research findings are presented through the lens of the following four categories: collinearity diagnostics, spatial autocorrelation analysis, kernel density (KD) findings, and multivariate geographically weighted regression (MGWR) analysis. The collinearity diagnostics were applied to examine the interrelationships among 18 independent environmental variables. The results indicate the absence of significant multicollinearity concerns, with most variables showing values below the critical threshold of five for variance inflation factors (VIFs). The selected variables indicate minimal intercorrelation, suggesting that researchers should be confident utilizing them in subsequent modelling or regression analyses. A spatial autocorrelation analysis using Moran's Index revealed positive spatial autocorrelation and significant clustering patterns in the distribution of live and non-functional Aini Falajs. High concentrations of live or dead Falajs tended to be surrounded by neighbouring areas with similar characteristics. These findings provide insights into the ecological preferences and habitat associations of Aini Falajs, thereby aiding conservation strategies and targeted studies. The kernel density (KD) analysis depicted distribution patterns of live and dry Aini Falajs through hotspots and cold spots. Specific regions exhibited high-density areas of live Falajs, indicating favourable environmental conditions or historical factors contributing to their concentrated distribution. Identifying these high-density zones can enhance our understanding of the spatial patterns and potential factors influencing the prevalence and sustainability of Aini Falajs. The multivariate geographically weighted regression (MGWR) models revealed strong associations between the live or dead status of Aini Falajs and environmental factors. The precipitation, topographic wetness index (TWI), aspect and slope exerted positive impacts on the live status, while evaporation, solar radiation, distance to drains and drain density exerted negative influences. Similar associations were observed for the dead status, emphasising the importance of controlling evaporation, shading mechanisms, proper drainage planning and sustainable land-use practices. This study provides valuable insights into the spatial distributions and factors influencing the live and dead status of Aini Falajs, thereby contributing to our understanding of their ecological dynamics and guiding conservation efforts and management strategies.

Deciphering genetic diversity in conserved cattle bulls to achieve sustainable development goals

The primary objective of Sustainable Development Goal target 2.5 established by the United Nations is to ensure the preservation of genetic diversity in domesticated animals. The ICAR-National Bureau of Animal Genetic Resources in India has been actively engaged in the conservation of cattle and buffalo bull semen for long-term storage. This present study aimed to assess the genetic diversity present in the conserved cattle bull semen, which would aid in determining the most suitable strategy for future conservation management. A total of 192 bull semen belonging to 19 cattle breeds were selected to evaluate genetic diversity using 17 pairs of FAO recommended microsatellite primers. Total 267 alleles were detected across all the samples which indicates substantial amount of allelic variation is being maintained in conserved bulls. Further, all cattle bulls semen conserved showed higher observed heterozygosity than expected heterozygosity which indicates excess genetic diversity in all the populations. The FST, F IT and FIS value across the loci and population is 0.146 ± 0.009, 0.054 ± 0.038, and − 0.105 ± 0.035, respectively, which suggests lack of inbreeding in conserved cattle bull semen. This study has established genetic diversity in conserved cattle semen samples to achieve sustainable development goals. In addition, it provides compelling evidence that the current approach for conserving cattle bull semen is heading in the correct direction.

Living on the edge: Insights into habitat patterns of forest-dwelling mammals in the buffer zone of Melghat Tiger Reserve, India

Buffer zones surrounding protected areas act as interfaces between humans and wildlife, providing sustainable resource utilization while minimizing negative interactions. This study analyzed data from camera trap sampling to understand habitat use and the effects of anthropogenic impacts on medium and large-sized forest-dwelling mammals in the buffer zone of Melghat Tiger Reserve in Central India. The human population in this region is increasing at a rate of 15 % in a decade. There are instances of human death and injury and frequent cattle lifting by carnivores. Crop damage by wild herbivores is common. These factors impede long term conservation goals in the tiger reserve. Camera trap sampling was carried out in the buffer zone for a period of 33 to 46 days. Camera trap data were analyzed using occupancy modeling to estimate habitat use probability (Ψ) and detection probability (p). Naïve estimates of habitat use ranged from 0.11 to 0.64, while Ψ values based on occupancy modeling ranged from 0.23 to 0.71. The study showed a fairly high level of habitat use by mammals in the buffer zone of the tiger reserve. Leopards were found to be associated with abundance of large prey species and human presence. Hyena, gaur, and sambar showed an association with forest cover, while nilgai showed association with scrubland. Chausingha and langur showed an association with sloping terrain. Overall, the study showed that the buffer zone plays an important role as a wildlife habitat and provided insights for prioritizing conservation efforts and management strategies in the study area.

Orchid trade at the source: Epiphytic species with conspicuous flowers in low‐elevation forests are more locally collected in a Philippine key biodiversity area

AbstractOrchids are the most heavily traded plant group globally, putting pressure on wild populations in many source countries like the Philippines. Despite its rich orchid diversity, there remains a notable gap in understanding the factors driving orchid trade within the country. To address this knowledge gap and support orchid conservation efforts, we utilized a 5‐year orchid diversity dataset extensively collected through floristic field and village garden surveys in one of the largest key biodiversity areas in the southern Philippines. We employed a trait‐based approach to investigate ecological drivers of local orchid collection within this source area. Our results show that around 36% of local orchid diversity have predicted collection risks of ≥50%. Notably, locally collected orchid species exhibited multiple, large, and conspicuously colored flowers that are found in low‐elevation forests and higher up in forest stratum. Elevational distribution and flower size emerged as the strongest predictors, potentially influencing collection preferences. Our analysis of predicted collection risks underscores the vulnerability of both threatened and non‐threatened orchid species to local collection pressures. Moreover, we highlight the practical utility of our trait‐based approach in predicting risks and informing management strategies for local orchid conservation. This research marks a significant step toward identifying ecological drivers influencing orchid trade at its source, providing insights that can inform targeted conservation strategies across many key biodiversity areas for this highly diverse, charismatic, and threatened plant family.

Enhancing tree species conservation in Burkina Faso through indigenous knowledge

Natural resources such as plant plays an important role in the livelihood of many local people in Africa. The high anthropogenic pressure on plant resources lead to their disappearance. Assessing ethnobotanical knowledge is useful for development of management and conservation of plant resources. Focusing on woody plants, our ethnobotanical investigations involved 60 randomly selected households across two Sahelian villages. Through semi-structured interviews, we meticulously assessed indigenous knowledge and perceptions related to the conservation of 41 woody plant species spanning 32 genera and 15 families.Our analysis categorized these species based on their diverse uses, encompassing food, medicine, fodder, construction, energy and art. The most dominant families reported Fabaceae and Combretaceae followed by Malvaceae. Notably, fruits, leaves, bark, and seeds emerged as the most valued plant organs.Crucially, our findings pinpointed human activities as the primary threat to species conservation, overshadowing climatic factors. We further identified key species and prioritized those in need of urgent conservation efforts. This study underscores the imperative of incorporating indigenous knowledge and perceptions into the development of effective conservation management strategies for plant resources in Sahelian zone.

When less is more: Updates in active surveillance and watchful waiting in the management of prostate cancer.

Prostate cancer is the second most common cancer among men globally. A range of management options are available for prostate cancer, including surgery, radiation therapy, hormone therapy, chemotherapy, or surveillance. Conservative strategies include active surveillance and watchful waiting, which differ in their intent. We provide a targeted instructive management algorithm for improving understanding of conservative strategies inprostate cancer. Active surveillance involves close monitoring with curative intent when there is evidence of disease progression. Incontrast, watchful waiting is palliative in intent and focuses on delaying treatment until symptoms or complications develop. Conservative approaches have demonstrated similar long-term oncological outcomes toradical treatment, while reducing harm from overtreatment, and maintaining quality of life by avoiding potential side effects such as urinary incontinence and erectile dysfunction. The decision to employ a conservative approach is determined by both patient and disease factors. Conservative management strategies play a vital role in the management of prostate cancer.

Salvage procedures for infected penile implants: A comprehensive review and analysis of functional outcomes

BackgroundThe salvage procedure for infected penile implants (IPs) has been a subject of interest since its inception in the late 1980s, yet its widespread adoption remains limited. The aim of this study was to realize a systematic literature review to provide a comprehensive analysis of salvage techniques for IPs and assess their efficacy, specifically focusing on functional success. MethodsA systematic literature review was conducted using PubMed, employing Mesh terms related to penile prosthesis, penile implant, infection, and salvage procedures. Articles in French or English were considered for the final analysis, with exclusion of literature reviews. ResultsFifteen articles detailing various salvage techniques for IPs were identified. Mulcahy's initial technique was described in 1996, and consisted of complete removal of infected components, extensive lavage, and subsequent replacement with a similar implant. Success rates ranged from 80% to 100%, with emerging trends favoring the use of malleable implants during salvage. Unfortunately, functional data remained limited. When salvage penile prosthesis placement involved a malleable prosthesis, between 20% and 33% of patients underwent conversion to hydraulic prosthesis. ConclusionThe salvage procedure for infected penile implants is a reliable method, with success rates surpassing 80%. The need for comparative studies assessing the type of implant used during salvage is required to tailor conservative management strategies for optimal patient outcomes. Finally, few data have been published regarding subsequent conversions from malleable penile implants to hydraulic penile implants after salvage.
