Authors: Balbinot Gabriela de Souza , Celeste Roger Keller , Montagner Francisco , Collares Fabricio Mezzomo
Published: August 2022

Aim: This study analyzed public procurements for different endodontic materials used in the Brazilian public health system and evaluated the variables related to their cost. Methods: A time-series study was performed by screening materials for endodontic application in the public Brazilian Databank of Healthcare Prices from 2010 to 2019. Data were categorized according to material composition and clinical application. The collated variables were used in a multiple linear regression model to predict the impact of unit price in procurement processes. Results: A total of 5,973 procurement processes (1,524,693 items) were evaluated. Calcium hydroxides were found in 79% of the observations (4,669 processes). Prices drop each year by US$1.87 while MTAs and epoxy resins are increasingly purchased at higher prices (US$50.87; US$67.69, respectively). The microregion, the procurement modality, and the type of institution had no influence on unit prices in the adjusted model (p > 0.05). Conclusions: Calcium hydroxide-based materials were the cheapest and most frequently purchased endodontic materials in the public health care system. Novel formulations are being implemented into clinical practice over time and their cost may be a barrier to the broad application of materials such as MTAs, despite their effectiveness.

Aims: Palbociclib has been approved in combination with endocrine therapy (ET) for hormone receptor-positive (HR+)/human epidermal growth factor receptor 2-negative (HER2-) advanced breast cancer (ABC), regardless of age. Even though ABC is one of the most prevalent cancers in older patients, very few patients ≥ 65 years old were included in pivotal trials. Therefore, the current study evaluated the safety and efficacy of palbociclib in “real-world” routine treatment of unselected older patients with HR+/HER2- ABC. Methods: Data were collected on patients > 70 years old who were treated with palbociclib plus ET for HR+/HER2- ABC in our institution. We analyzed safety data (CTCAE v4.0 criteria) and outcomes, such as progression-free survival (PFS) and overall survival (OS), as well as any associations between main geriatric characteristics and our results. Furthermore, we assessed safety at a national level by analyzing all palbociclib-related adverse events (AEs) reported in the French Pharmacovigilance Database (FPVD) during the same period. Results: From February 2016 to July 2019, 52 patients were identified with a median age of 80.9 years, of whom 88% presented an AE. The most common grade 3-4 AE was neutropenia (64%). Median PFS and OS were nine months and not reached, respectively. The FPVD reports 227 cases of palbociclib-related AEs, with older and younger patients sharing similar characteristics. Conclusion: Palbociclib is well tolerated in older patients with efficacy comparable to that in younger patients. However, the addition of palbociclib to ET should be evaluated individually in this older and frailer subgroup.
Effect of cofactors on NAFLD/NASH and MAFLD. A paradigm illustrating the pathomechanics of organ dysfunction
Authors: Lonardo Amedeo , Singal Ashwani , Osna Natalia , Kharbanda Kusum K.
Published: August 2022

Primary nonalcoholic fatty liver disease (NAFLD) is bi-directionally associated with the metabolic syndrome and its constitutive features (“factors”: impaired glucose disposal, visceral obesity, arterial hypertension, and dyslipidemia). Secondary NAFLD occurs due to endocrinologic disturbances or other cofactors. This nosography tends to be outdated by the novel definition of metabolic associated fatty liver disease (MAFLD). Irrespective of nomenclature, this condition exhibits a remarkable pathogenic heterogeneity with unpredictable clinical outcomes which are heavily influenced by liver histology changes. Genetics and epigenetics, lifestyle habits [including diet and physical (in)activity] and immunity/infection appear to be major cofactors that modulate NAFLD/MAFLD outcomes, including organ dysfunction owing to liver cirrhosis and hepatocellular carcinoma, type 2 diabetes, chronic kidney disease, heart failure, and sarcopenia. The identification of cofactors for organ dysfunction that may help understand disease heterogeneity and reliably support inherently personalized medicine approaches is a research priority, thus paving the way for innovative treatment strategies.

Published: August 2022

In vitro propagation of bromeliads is widely used to produce plantlets intended for conservation. This study aims at evaluating physiological responses of Aechmea setigera in vitro cultured under different concentrations of 6-benzylaminopurine (BAP). The experiment was conducted in completely randomized design with five treatments (0, 1.0, 2.0, 4.0 and 8.0 mg L-1 of BAP). After 90 days of in vitro cultured in stationary liquid MS culture medium it were assessed morphological and biochemical parameters. The BAP increment increased stomatal density, reduced plant size and root number, but increased the number of shoots. There was significant effect of BAP dose on fresh and dry mass. High BAP doses (4.0 and 8.0 mg L-1) promoted the reduction of chlorophyll a and total chlorophyll content, but there was no change of chlorophyll b and carotenoids. The concentration of starch and total soluble carbohydrates decreased above 2.0 and 4.0 mg L-1 of BAP, respectively. The total phenolic content decreased with increasing BAP concentrations. Evaluated changes in metabolism elucidate the phenotypic plasticity for in vitro multiplication process in A. setigera.

Published: August 2022

Estuda-se a automedicação da população com base em informações na Internet durante a pandemia da COVID-19.  O problema de pesquisa é: em que medida a população se automedicou com base em informações veiculadas pela internet, durante a pandemia de COVID-19? O objetivo deste trabalho é identificar e descrever como a população buscou, em conteúdos na internet, medicamentos diversos para se automedicar durante a pandemia. Trata-se de pesquisa descritiva, de abordagem quanti-qualitativa de corte transversal.  A pesquisa é considerada de opinião, de acordo com a Resolução 510/2016 da CONEP. Os dados foram coletados a partir de um questionário elaborado para atingir os objetivos da pesquisa e foram disponibilizados pelo Google Forms, entre fevereiro e março de 2021. 54 participantes distribuídos em 14 homens e 40 mulheres de diferentes cidades do país. Entre esses, 36 afirmaram ter buscado orientações na internet sobre medicamentos para a COVID-19, entre os quais destacam-se: vitaminas em geral; vermífugos e medicamentos para aumentar a imunidade. Concluiu-se que o distanciamento social e a redução do contato com outros semelhantes conduzem a um gasto de tempo maior diante de aparelhos conectados à internet, o que por conseguinte pode acarretar a automedicação, mesmo em pessoas com nível educacional mais elevado.

Authors: Arisudhana Gede Arya Bagus , Martini Ni Made Dwi Ayu
Published: August 2022

Clinical reasoning has an important role in nursing care. Therefore, an appropriate learning model is needed to produce great clinical reasoning among nursing students. The blended learning method is a flexible and technology-based learning model that has the potential to improve nursing students’ clinical psychomotor skills and overall performance. This study aims to determine the effect of the blended learning method on the clinical reasoning ability of nursing students. This was a quasi-experimental study that used a pretest-posttest design and a control group. The number of samples was 35 respondents in each group. The samples were recruited using a simple random sampling method. The intervention was conducted for 14 weeks in the intervention group. Clinical reasoning was measured using the Clinical Reasoning Assessment Tools (CRAT). Data were then analyzed using the Mann-Whitney test. There were differences in the clinical reasoning ability between the experimental group (p <0.001) and the control group (p = 0.128). A positive effect was found between the blended learning method and clinical reasoning ability among nursing students. Thus, a flexible learning process can provide repetition and continuity of the learning process and improve the students' critical thinking processes.

The number of PTKIS Lecturers in the Cianjur Regency filled out the questionnaire was 78. 83 Lecturers in Sukabumi District and 105 in Bogor District were used as research samples. Meanwhile, the data analysis technique used multiple linear regression.Findings − Halal certification affects buying intention of halal products at PTKIS Lecturers in Cianjur, Sukabumi, and Bogor Regencies. Halal awareness only affects Cianjur and Bogor Regencies. Meanwhile, in Sukabumi Regency, the effect was not significant. Food composition has an impact in Sukabumi District, but it does not substantially influence Cianjur and Bogor Regencies.Implication − Producing or selling food for producers needs to consider three factors: halal certification, awareness, and food ingredients. Consumers must pay attention to the halal logo to ensure that the products consumed are truly halal and follow Islamic teachings.Originality − Halal certification is an essential key for business product development. Meanwhile, most lecturers do not use food composition as the primary reference in choosing halal products to buy. Halal awareness of PTKIS lecturers has different perceptions.
Entrepreneurship Education Model of Pesantren on Reducing Unemployment
Authors:   Universitas Negeri Semarang, Siswantoro Siswantoro
Published: August 2022

Several previous studies have found that entrepreneurship can be alternative to reducing unemployment. Pesantren graduates are considered to have the potential to contribute to the average number of unemployed due to the lack of competence of students. On the other hand, as community-based institutions, many pesantren have potential that can be empowered. Therefore, the purpose of this study is to design a model of entrepreneurship education in pesantren. The research method used is a qualitative type with a literature study approach. The data used in this study are secondary in the form of journal articles, news, government reports, and other relevant sources. The data is then analyzed and integrated with the views of this researcher to produce a new concept in the form of an empowerment model through pesantren entrepreneurship education. The results of this study indicate that the designed model could be a solution to improve the entrepreneurial competence of students. The model consists of four important steps such as identifying business potential, capitalization of capital, capacity building of pesantren managers, and implementation of entrepreneurship education. Implementing the pesantren entrepreneurship education model requires contributions from various stakeholders such as governments, private sectors, communities, and universities.

Published: August 2022

Indonesian government has been compelled to establish various learning approaches during this pandemic due to the spread of Covid-19 and the rising number of new cases, including distance learning and limited face-to-face learning. This study explores students' opinions about online learning, limited face-to-face learning, and face-to-face learning. The research was conducted at MAN 4 Jakarta. This study is situated in the mixed method. Data triangulation was carried out through field observations, surveys with 139 respondents, and structured interviews with 8 students. The survey results show that 47.5% of students prefer limited face-to-face learning with 1 day of face-to-face learning and 4 days of online meetings in one week. 38.1% of students prefer face-to-face learning, and 14.4% prefer online learning. The interviews suggest that students prefer face-to-face learning and limited face-to-face learning due to problems with internet connection. Offline and hybrid learning allow students to communicate with teachers easier. It offers an environment scaffolding learning enthusiasm. While some students choose online learning since it is less expensive and requires less time and effort to attend class, face-to-face learning is the most preferred by students.
On the Meaning of Local Realism
Authors: Lambare Justo Pastor
Published: August 2022

We present a pragmatic analysis of the different meanings assigned to the term "local realism'' in the context of the empirical violations of Bell-type inequalities since its inception in the late 1970s. We point out that most of them are inconsistent and arise from a deeply ingrained prejudice that originated in the celebrated 1935 paper by Einstein-Podolski-Rosen. We highlight the correct connotation that arises once we discard unnecessary metaphysics.
Enhanced Communications on Satellite-based IoT Systems to Support Maritime Transportation Services
Authors: Monzon Baeza Victor , Ortiz Flor , Herrero Garcia Samuel , Lagunas Eva
Published: August 2022

Maritime transport has become very important due to its ability to internationally unite all continents. In turn, during the last two years, we have observed that the increase of consumer goods has resulted in global shipping deadlocks. In addition, the future goes through the role of ports and efficiency in maritime transport, with the aim of decarbonizing its impact on the environment. In order to improve the economy and people's lives, in this work, we propose to enhance services offered in maritime logistics. To do this, a communications system is designed on the deck of ships to transmit data through a constellation of satellites using interconnected smart devices based on IoT. Among the services, we highlight the monitoring and tracking of refrigerated containers, the transmission of geolocation data from GPS, and security through AIS. This information will be used for a fleet of ships to make better decisions and help guarantee the status of the cargo, as well as maritime safety on the routes. The system design, network dimensioning, and a communications protocol for decision-making will be presented.
Split Ring Resonator Network and Diffused Sensing Element Embedded in a Concrete Beam for Structural Health Monitoring
Authors: Cataldo Andrea , Pittella Erika , Schiavoni Raissa , Monti Giuseppina , Masciullo Antonio , Scarpetta Marco , Piuzzi Emanuele
Published: August 2022

The aim of this work is to propose two different and complementary sensors for the structural health monitoring of concrete beams. In particular, a diffused sensing element and a split ring resonator network are presented. The first sensor is able to detect the variation of the dielectric properties of the concrete along the whole beam length, for a diffuse monitoring both during the important concrete curing phase and also for the entire life cycle of the concrete beams. The resonators instead work punctually, in their surroundings, allowing an accurate evaluation of the permittivity both during the drying phase and after. This allows the continuous monitoring of any presence of water both inside the concrete beam and in points that can be critical, in the case of beams in dams, bridges or in any case subject to a strong presence of water which could lead to deterioration, or worse, cause serious accidents. Moreover, the punctual sensors are able to detect the presence of cracks in the structure and to localize them.

Dengue Fever (DF) is an important arthropod-borne viral infection, which has repeatedly oc-curred as outbreaks in eastern and northeastern Ethiopia since 2013. A cross-sectional epidemio-logical outbreak investigation was carried out from September - November 2019 on febrile pa-tients (confirmed malaria negative) who presented with suspected and confirmed DF at both public and private health facilities in Gewane District, Afar Region, northeastern Ethiopia. Ento-mological investigation of containers found in randomly selected houses belonging to DF positive patients was undertaken, to survey for the presence of Aedes larvae or pupae. A total of 1185 DF cases was recorded from six heath facilities during the 3-month study period. The mean age of DF cases was 27.2 years and 42.7% of the cases were female. The most affected age group was 15-49 years (78.98%). However, the attack rate (AR) was highest in the 49+ age group (134.2). A total of 162 artificial containers were inspected from 62 houses, with 49.4% found positive for Aedes larva/pupae. Aedes mosquitoes were mostly found breeding in buckets/bowls, clay jars, plastic tanks, and tires. World Health Organization entomological indices classified the study site as high risk for dengue outbreaks (House Index=45.2%, Container Index=49.4% and Breteau In-dex=129). Study findings highlight the importance of vector control to prevent future dengue out-breaks in the region. The scarcity of drinking water and changing climactic conditions may have also contributed to the occurrence of this outbreak.
Two Decades-long Satellite Observations of Carbon Monoxide Confirm the Northern Hemispheric Wildfires Increase
Authors: Yurganov Leonid , Rakitin Vadim
Published: August 2022

Biomass burning is an important and changing component of the global and hemispheric carbon cycles. Boreal forest fires in Russia and Canada are significant sources of greenhouse gases carbon dioxide (CO2) and methane (CH4). The influence of carbon monoxide (CO) on the greenhouse effect is practically absent: its main absorption bands of 4.6 and 2.3 μm are far away from the climatically important spectral regions. Meanwhile, CO concentrations in fire plumes are closely related to CO2 and CH4 emissions from fires. On the other hand, satellite measurements of CO are much simpler than those for the aforementioned gases. The Atmospheric Infrared Sounder (AIRS) provides a satellite-based CO data set since October, 2002 up to now. This communication presents estimates of CO emissions from biomass burning north of 30° N using a simple two-box mass-balance model. These results correlate closely with independently estimated CO emissions from the GFED4 bottom-up data base. Both ones reported record high emissions in 2021 throughout two decades, double the annual emissions comparing to the previous years. There have been two years with extremely high emissions (2003 and 2021), but for the rest of data upward trend with a rate of 3.6 ± 2.2 Tg CO yr-2 (4.8 ± 2.7% yr-1), was found. A similar rate of CO emission follows from the GFED4 data.
Overexpressed C-Myc Sensitize Cells to TH1579, an Mitotic Arrest and Oxidative DNA Damage Inducer
Authors: Henriksson Sofia , Calderón-Montaño José Manuel , Solvie Daniel , Warpman Berglund Ulrika , Helleday Thomas
Published: August 2022

Previously, we reported that MTH1 inhibitors TH588 and TH1579 selectively induce oxidative damage and kill Ras expressing or transforming cancer cells, as compared to non-transforming immortalized or primary cells. While this explains the impressive anti-cancer properties of the compounds, the molecular mechanism remains elusive. Oncogenes induce replication stress, re-sulting in under replicated DNA and replication continuing into mitosis, where TH588 and TH1579 treatment cause toxicity and incorporation of oxidative damage. Hence, we hypothesized that oncogene-induced replication stress explains the cancer selectivity. To test this, we overex-pressed c-Myc in human epithelial kidney cells (HA1EB), resulting in increased proliferation, polyploidy and replication stress. TH588 and TH1579 selectively kill c-Myc overexpressing clones, enforcing the cancer cell selective killing of these compounds. Moreover, the toxicity of TH588 and TH1579 in c-Myc overexpressing cells is rescued by transcription, proteasome or CDK1 inhibitors, but interestingly not by nucleoside supplementation. This suggest that cancer selectivity is unrelated oncogene-induced replication stress. We conclude that the molecular toxi-cological mechanisms how TH588 and TH1579 kill c-Myc overexpressing cells have several com-ponents and involves MTH1-independent proteosomal degradation of c-Myc itself, c-Myc driven transcription and CDK activation, and is likely unrelated to oncogene-induced replication stress.

This research aims to obtain empirical evidence of the influence of the masculinity of male CEOs on the of research & development, this research seeks to identify the influence of the face of mas-culinity of male CEO’s on the of research & development. The study used a quantitative approach with population and research samples using companies listed on the Indonesia Stock Exchange from 2016 to 2021. The study collected images of faces identified as male CEOs from data from the Indonesia Stock Exchange website and company as utilizing Google searches. The data analysis method in this study used Regression Ordinary Least Square (OLS) with Stata Software. Stata software is one of the regression completion procedures that has a high degree of flexibility in re-search that connects theories, concepts and data that can be done on variables in research. The findings empirically explain that the higher the face value of male CEO masculinity has an impact on reducing research & development costs, and vice versa the lower the face value of male CEO masculinity has an impact on increasing research & development. The practical implications of the research results can help the Indonesian Association of Accountants in developing Financial Accounting Standard No. 19 in Indonesia. The theoretical implications of the research results can explain the Theory of Agency and the Theory of Consistency of Behavior. The policy implications of the results of the study can provide empirical evidence that the higher the facial value of male CEO masculinity has an impact on reducing research & development, while also the lower the face value of male CEO masculinity has an impact on increasing research & development.

In this article we investigate the determinants of the European “Most Cited Publications”. We use data from the European Innovation Scoreboard-EIS of the European Commission for the period 2010-2019. Data are analyzed with Panel Data with Fixed Effects, Panel Data with Random Effects, WLS, and Pooled OLS. Results show that the level of “Most Cited Publications” is positively associated, among others, to “Innovation Index” and “Enterprise Birth” and negatively associated, among others, to “Government Procurement of Advanced Technology Products” and “Human Resources”. Furthermore, we perform a cluster analysis with the k-Means algorithm either with the Silhouette Coefficient and the Elbow Method. We find that the Elbow Method shows better results than the Silhouette Coefficient with a number of clusters equal to 3. In adjunct we perform a network analysis with the Manhattan distance, and we find the presence of 4 complex and 2 simplified network structures. Finally, we present a confrontation among 10 machine learning algorithms to predict the level of “Most Cited Publication” either with Original Data-OD either with Augmented Data-AD. Results show that the best machine learning algorithm to predict the level of “Most Cited Publication” with Original Data-OD is SGD, while Linear Regression is the best machine learning algorithm for the prediction of “Most Cited Publications” with Augmented Data-AD.

“Hyper-adaptability” is the capability of the central nervous system (brain and spinal cord) to manage the impairment of sensory, motor, and cognitive functions by reactivating and recruiting pre-existing networks that are latent but available. In studying hyper-adaptability, interdisciplinary research that integrates mathematical modeling and robotic technologies with neuroscience findings is important. Thanks to support from Japan’s Ministry of Education, Culture, Sports, Science and Technology (MEXT) in the form of Grant-in-Aid for Scientific Research on Innovative Areas, the Hyper-adaptability Research Project started in July 2019.

The research works reported in this special issue are the latest achievements of the Hyper-adaptability Research Project. The special issue consists of three review articles and 10 research papers. These contributions cover a wide range of hyper-adaptability research activities, including neurophysiological experiments, functional neuroimaging, mathematical modeling of brain and musculoskeletal systems, cognitive psychological experiments, and robotic / virtual reality interventions for neurorehabilitation, carried out to clarify the mechanisms of hyper-adaptability.

We thank the authors for submitting their latest achievements and the reviewers for dedicating their time and effort to the review process. We also thank the editorial board of the Journal of Robotics and Mechatronics for supporting the publication of this special issue.

Among several perceptive traits of virtual reality, the relationship between the physical body and a self-avatar is unclear. In this study, we investigate a case of hyper-adaptability, i.e., the capability of users to adjust to the movements of an altered self-avatar when such movements abruptly and frequently change. Focusing on movements of the upper limbs, we show experimentally the effect of the frequency of variations in virtual body alterations on adaptability. Moreover, we report a positive evaluation of the sense of embodiment and the overall user experience with virtual reality, and finally underline how these studies can be considered a basis for the design and development of virtual rehabilitation systems.

Sit-to-stand motion is an important daily activity, and disability of motion can significantly reduce quality of life. Therefore, it is important to understand the mechanism of sit-to-stand motion in order to prevent such scenarios. The sit-to-stand motion was found to be generated by four muscle groups, through muscle synergy. However, it is unclear how muscle synergy can be controlled. Human sit-to-stand motion may be planned based on body condition before motion. In this study, we aimed to clarify the relationship between body condition and muscle activity during the sit-to-stand motion. Accordingly, we measured the muscle activity when knee movability was disturbed as a condition of body change. We also measured the muscle activity during normal sit-to-stand motion and sit-to-stand motion with disturbed knee movability using surface electromyography. Subsequently, we extracted the muscle synergy from the measured muscle activity and compared the activity levels of muscle synergy. The results revealed that muscle activity contributing to forward bending increased and that contributing to the rise of the hip and stabilization decreased when knee movability was disturbed. These results suggest that humans compensate for disturbed knee movability with forward momentum and bending motion. Moreover, this implies that humans adjust their motion to various environments or body conditions by adjusting the level of forward bending activity.

For autonomous navigation, we have thus far proposed MCL using environmental maps based on cadastral data. However, buildings in the cadastral data sometimes differ from their actual positions in the environment. As the environmental map is generated from the cadastral data, the inconsistency affects the localization performance. For this problem, we propose an online SLAM approach in the actual environment. A mobile robot simultaneously localizes the position and builds another online map using NDT scan matching. In contrast to other offline SLAM approaches, however, pose graph optimization for loop closure is not executed during online SLAM. As a result, the online map is distorted by localization errors. For this challenge inherent in online SLAM, the localization errors are modified using MCL and wheel odometry in a hybrid manner. As a contribution to autonomous navigation, the robot is enabled to localize the position even in a new place. In the experiments, we show that the localization performance of the robot in an outdoor environment with inconsistent buildings is improved compared to other online approaches with and without modifications.

This paper presents a localization method using deep learning and light detection and ranging (LiDAR) for unmanned ground vehicle (UGV) in field environment. We develop a sensor fusion algorithm that UGV recognizes natural objects from RGB camera using deep learning and measures the distance to the recognized objects with LiDAR. UGV calculates its position relative to the objects, creates a reference path, and then executes path following control. The method is applied to autonomous mowing operation in orchard. A mower is tracked by UGV. UGV needs to run along a tree row keeping an appropriate distance from tree trunks, by which the mowing arm of the tracked mower properly touches the trunks. Field experiments are conducted in pear and apple orchards. UGV localizes self position relative to trees and performs autonomous mowing successfully. The results show that the presented method is effective.

Navigation requires self-localization, which GPS typically performs outdoors. However, GPS frequently introduces significant errors in environments where radio reflection occurs, such as in urban areas, which makes precise self-localization occasionally impossible. Meanwhile, a human can use street view images to understand their surroundings and their current location. To implement this, we must solve image matching between the current scene and the images in a street view database. However, because of the wide variations in the field angle, time, and season between images, standard pattern matching by feature is difficult. DeepMatching can precisely match images with various lighting and field angles. Nevertheless, DeepMatching tends to misinterpret street images because it may find unnecessary feature points in the road and sky. This study proposes several methods to reduce misjudgment: (1) gaining image similarity with features such as buildings by excluding the road and sky, and (2) splitting the panoramic image into four directions and matching in each. This study shows the results of each method and summarizes their performance using various images and resolutions.
Concomitant Achilles Tendon Lengthening with Transmetatarsal Amputation for the Prevention of Late Forefoot Ulceration

Published: August 2022

Background:

Late development of forefoot ulcers is a common finding after transmetatarsal amputation (TMA). The primary aim of this study was to examine whether concomitant prophylactic Achilles tendon lengthening (ATL) was associated with a reduction in the incidence of forefoot ulcers postoperatively.

Methods:

A retrospective chart review was performed by 2 authors to identify patients who underwent TMA over a period of 5.5 years from January 1, 2015, through July 31, 2020. They identified 110 feet in 107 patients; the 83 patients (85 feet) who had ≥120 days of follow-up were used for the study. Follow-up was performed with telephone calls (80 patients) or during the last office visit (3 patients). Those who were contacted by telephone were asked if they developed an ulcer after healing from the original surgery. Mean follow-up time was 672 ± 258 days for the 30 feet with concomitant Achilles lengthening and 663 ± 434 days for the 55 feet without Achilles lengthening. Demographic data were analyzed for association with late development of forefoot ulceration.

Results:

Eighty-five feet were included in the analysis. Late forefoot ulcers developed in 35% of feet that had a TMA alone (n = 55) compared with 3% of feet who received a concomitant ATL (n = 30; p < 0.001); the 2 groups had similar mean follow-up times. Mean time to ulcer development was 587 ± 420 days in the 19 patients without Achilles lengthening. Of the patients who developed late forefoot ulcers, 47% also developed osteomyelitis, and 16% went on to proximal amputation. Patients who developed forefoot ulcers were younger (55 ± 12 versus 63 ± 11 years of age; p = 0.006) than those who did not.

Conclusions:

ATL at the time of TMA is associated with a reduction in the risk of later development of forefoot ulcers, especially in younger patients.
