Introduction: Fibular- and tibiofibular-based reconstructions are the gold standard treatment for posterolateral corner (PLC) injuries of the knee. This is the first report describing a wholly tibial-based PLC reconstruction.

Case Report: A 50-year-old female presented with knee instability following proximal fibular resection for a benign tumor, associated with chronic anterior cruciate ligament (ACL) deficiency from a previous injury. Magnetic resonance imaging (MRI) showed fibular collateral ligament (FCL) and distal biceps femoris complete detachment. ACL reconstruction was combined with revision PLC reconstruction, placing the distal grafts, due to lack of fibula, both into the tibia. At 24-month follow-up, the patient reported excellent clinical outcomes.

Conclusion: In cases related to proximal fibula deficiency from resection or congenital causes, a wholly tibial-based PLC reconstruction can effectively restore stability.

Keywords: Proximal fibular resection, knee instability, posterolateral corner reconstruction.

Background: Despite the good clinical outcomes of osteochondral autograft transplantation (OAT), reports of re-arthroscopic findings after OAT have been limited to short-term, and there are no reports of findings after long-term follow-up. This is the first report that describes re-arthroscopic findings long-term after OAT.

Case Report: A male patient underwent OAT on the lateral femoral condyle (LFC) of the knee and lateral meniscus (LM) repair at the age of 45. Eighty years after the primary surgery, he underwent re-arthroscopy because of cartilage injury on the medial femoral condyle (MFC) and LM tear. The re-arthroscopic findings showed the retained OAT plugs on LFC and severe damage of LM. After OAT on the LFC and meniscectomy of LM was performed, his knee symptoms improved, so the LFC that had undergone OAT 18 years previously was considered to be on a good clinical course.

Conclusion: OAT plugs were retained at the long-term follow-up while the repaired LM was severely damaged. The structural robustness of OAT was thought to be responsible for good long-term clinical outcomes.

Introduction: Bilateral simultaneous rotational ankle fractures are an unusual phenomenon that remains unreported in the English literature, and to our knowledge, about 10 cases have been reported. The aim of the study was to evaluate and report clinical outcomes of bilateral simultaneous ankle fractures in our institution.

Case Report We conducted a review of our 2-year experience with patients who had simultaneous bilateral fractures of the ankles and were treated at our institution. The included patients underwent surgical treatment using open reduction and internal fixation. Patients’ functional outcomes were assessed using patient-reported outcome measures (PROMs), namely the Short Form-36 questionnaire and the Olerud and Molander Ankle Outcome Score (OMAS).

Results: Two cases (four ankles) of simultaneous bilateral rotational ankle fractures were identified in our institution’s records. Both cases involved a pedestrian motor vehicle accident. They were both female and had an average age of 22.5 years. Due to an open injury, one ankle underwent a staging procedure, and the other three underwent open reduction and internal fixation with excellent clinical outcomes. Functional outcomes were measured with PROMs.

Conclusion: Simultaneous bilateral ankle fractures, while uncommon, can have a substantial impact on an individual’s mobility and health-related quality of life. Early surgical intervention and effective rehabilitation enhance functional results in this devastating journey.

Introduction: Pressure injuries (PIs) continue to remain one of the most common and debilitating complications seen adding to the financial burden of the patients and caregivers. The available vacuum-assisted closure systems are expensive. In our case series, we have applied low-cost negative pressure dressing (NPD) for sacral PIs in five patients along with individualized rehabilitation protocol which resulted in accelerated healing of their PIs and improved functional outcome.

Materials and Methods: Five patients having PIs of Grade IV according to NPIAP classification in whom we applied NPD were included. Pressure ulcer scale for healing (PUSH), reduction of surface area of the wounds was recorded on a weekly basis. Functional independence measure (FIM) score of the patients was evaluated at admission and at discharge. Healing rate by means of PUSH score and surface area were recorded.

Results: Improvement in FIM score from the time of admission till at discharge was calculated to be 42.86% with a standard deviation of 16.84. Healing rate by means of PUSH score was the highest for Patient C at 3.57% per week and in terms of surface area for Patient C at 5.44% per week.

Conclusion: Low-cost negative pressure device has been observed to be a safe and effective method of managing PIs. It prevents further infection and helps to optimize and accelerate healing in PIs with the additional advantage of being cost-effective and easy to apply.

Introduction: Coronavirus disease 2019 (COVID-19) infection or corticosteroid usage during the COVID-19 pandemic as risk factors for avascular necrosis (AVN) of the femoral head (osteonecrosis of the femoral head/femoral head AVN [FHAVN]), as well as its link to clinical and radiological outcomes, are poorly understood. Osteonecrosis, which results from a disruption in vascular supply to the femoral head, is a prevalent cause of hip joint deterioration and one of the most common reasons for total hip arthroplasty (THA)/total hip replacement in India and other Asian countries. This study will aid in understanding the condition’s epidemiology and statistically determining the risk of disease related with pandemic exposure.

Materials and Methods: This is a retrospective study of 100 hips diagnosed with osteonecrosis/osteoarthritis of the femoral head that underwent THA at a tertiary care center before and after the COVID-19 pandemic between February 2014 and February 2024.

Results: Late stages of FHAVN, when the diagnosis requiring THA, following the pandemic have increased exponentially. It has also switched from affecting the middle-aged to the younger age groups. Furthermore, the bilaterality necessitating THA has increased considerably. There is a clear shift in the presentation of this disabling illness, as well as the need for THA, which otherwise is rarely carried out on younger people. Furthermore, data on how much corticosteroids were used in the treatment is disturbingly scant, and how it may have contributed to this ailment in India is still questionable.

Conclusion: The COVID-19 pandemic could be the most serious threat, causing late-stages FHAVN (stages 3 and 4 of the Ficat and Arlet classification), in an accelerated manner, necessitating THA and overburdening existing medical care.

Keywords: COVID-19, pandemic, osteonecrosis, femoral head, osteonecrosis of the femoral head/femoral head avascular necrosis, India, Asia, total hip replacement/total hip arthroplasty.

Published: January 2025

Introduction: Extreme beak calcaneal fractures (Type 2 Lee’s tuberosity avulsion fractures) are rare injuries, accounting for only 1.3–3% of all calcaneal fractures. These injuries are considered as surgical emergency as they can lead to significant functional impairment and soft-tissue compromise if not promptly managed. This study evaluates the efficacy of cannulated cancellous (CC) screw fixation for these fractures.

Materials and Methods: A prospective study of 14 patients with extreme beak calcaneal fracture (Type 2 Lee’s - tuberosity avulsion fractures) treated with CC screw fixation was conducted in VMMCH, Karaikal, Puducherry between June 2022 and June 2023. Patients were followed for a minimum of 12 months. Functional outcomes were assessed using the American Orthopedic Foot and Ankle Society (AOFAS) Ankle-Hindfoot scale.

Results: The mean AOFAS score at the final follow-up was 89.3 (range 78–98). Radiographic union was achieved in all cases by 20 weeks with a mean union time of 13.09 weeks in closed fractures and 18 weeks in open fractures. One patient developed a superficial wound infection without any alarming signs of hardware issues, which resolved eventually. No hardware failures or need for revision surgeries were observed.

Conclusion: Early intervention with CC screw fixation appears to be an effective and safe technique for the treatment of extreme beak calcaneal fracture (Type 2 Lee’s – tuberosity avulsion fractures), resulting in excellent functional outcomes and a low complication rate.

Abstract: This paper shows that the finite verbal form beith is unique for a variety of different reasons in Early and Early Modern Irish. It also argues that the history of the conjunction cía 'although' from Old to Modern Irish has been misunderstood, and that a correct understanding of it is at the core of statements in the grammatical and syntactical tracts.
A Chance to Be Kinder? Peer Status Profiles and Changes in Prosocial and Aggressive Behavior in Adolescence

Published: January 2025

Abstract: The well-known associations of peer status (acceptance and rejection) with prosocial and aggressive behaviors have mostly relied on peer status measures assessed at a single time point. This study adopted a person-oriented approach to examine longitudinal links between stable peer status profiles assessed at two time points and prosocial and aggressive behavior using latent profile analysis and latent transition analysis based on three waves of data collected among 324 Chilean adolescents (56.3% male, M age = 12.31, SD = 0.58). First, latent profile analysis identified four status profiles: moderately accepted, moderately rejected, controversial, and highly rejected. Second, we examined the 6-month stability of these profiles during the same academic year (seventh grade, Waves 1 and 2) with latent transition analysis. Results showed that the moderately accepted group was highly stable, with an 87% chance of remaining accepted at T2, followed by the highly rejected (78%), controversial (69%), and moderately rejected (49%), who had a 35% probability of moving into the accepted group. Third, we tested how stable status profiles at two time points predicted changes in prosocial and aggressive behavior during the transition from seventh to eighth grade (Wave 3). When the new academic year began, prosocial behavior increased for the moderately rejected group but not for the highly rejected group. Aggressive behavior decreased in the highly rejected and controversial groups. Implications for the role of stable peer status in the social behavior of early adolescents in educational settings are discussed, with particular attention to the transition to a new academic year.
Linear and passive silicon-on-insulator refractive index sensor utilizing Bragg grating-assisted Michelson interferometer
Authors: Gerguis John O. , Qi Minghao
Published: January 2025

In this work, we present a design for a linear and entirely passive refractive index (RI) sensor based on silicon-on-insulator (SOI) technology, addressing the need for sensors capable of monitoring continuously changing gas concentrations. Conventional RI sensors, based on interferometers, exhibit a nonlinear response, limiting their effectiveness for applications requiring consistent performance across a wide range of refractive index changes. The proposed configuration utilizes a Michelson interferometer and two long Bragg gratings to linearize the interferometer response, ensuring a constant figure of merit (FOM) across the entire range of changes in the cover medium's refractive index. A slotted Bragg grating is employed in the sensing arms to enhance the interaction between the light inside the waveguide and the surrounding medium. We demonstrate the sensor's operation and design using finite-difference eigenmode (FDE) and finite-difference time-domain (FDTD) simulations, followed by a theoretical analysis of its performance based on key design parameters, including grating properties, waveguide sensitivity, and phase delay. With a slot width of 80 nm and assuming a sensing arm index modulation depth (δnsen) of 0.01, the design achieves a waveguide sensitivity of ∼ 0.72 and a sensor with a constant FOM of ∼ 113 RIU−1. We fabricated several Bragg grating devices and Michelson interferometers based on slot and strip waveguides with oxide cladding, measured their responses, and compared these with simulations to validate the proposed design's functionality. The proposed sensor can be entirely exposed to air, simplifying the fabrication process by eliminating the oxidation step and the need for additional patterning of a window for the sensing area. This is made possible by the strong desensitizing factor (Srefδnsen/Ssenδnref) of the reference arm compared to the sensing arm. Consequently, the proposed sensor is well-suited for low-cost fabrication and mass production.
Propagators with user-defined object-plane pixel size for ptychography
Authors: Witte Stefan , Pelekanidis Antonios , Eikema Kjeld
Published: January 2025

Lensless imaging techniques have been developed to visualize objects with high robustness and unprecedented resolution. Lensless imaging is based on the numerical reconstruction of the complex-valued transmission or reflection function of the sample under investigation from optical diffraction measurements. Specifically, in coherent diffractive imaging (CDI) and ptychography, the reconstruction is the result of an iterative process of numerical forward and backward propagation of coherent light waves between the sample plane and a detector plane. However, in the standard propagation models the pixel size of the reconstructed object image is typically fixed and wavelength dependent. This property forms a limitation for CDI and ptychography with broadband illumination, and limits flexibility in general. Here we compare three propagation models for far-field propagation that allow user-defined pixel size at the object plane. We derive their analytical expressions and observe that all three models are in principle equivalent. Each propagator can be written in two distinct versions, which conceptually represent propagation via different intermediate planes. We perform propagation simulations and ptychographic reconstructions on experimental data to compare the performance of these different propagator versions. Our results show that the choice of intermediate plane can affect the reconstruction quality due to less strict sampling bandwidth requirements, which enables a wider choice of pixel sizes in the object plane. Our analysis provides guidelines for selecting an optimized object pixel size when performing reconstructions on broadband CDI and ptychography data.
Coastal carbon sentinels: A decade of forest change along the eastern shore of the US signals complex climate change dynamics

Published: January 2025

Increased frequency and intensity of storms, sea level rise, and warming temperatures are affecting forests along the eastern coast of the United States. However, we lack a clear understanding of how the structure of coastal forests is being altered by climate change drivers. Here, we used data from the Forest Inventory and Analyses program of the US Forest Service to examine structure and biomass change in forests along the mid-Atlantic, Southeastern, and Gulf coasts of the US. We selected plots that have been resampled at low (5 m) and mid (30–50 m) elevations in coastal areas of states from Texas to New Jersey, allowing us to determine change in live trees, standing dead wood, and downed dead wood biomass (and carbon) stocks across a decade at the county level. Forest area increased by 1.9% and 0.3% in low and mid elevation counties, respectively. Live tree biomass density increased by 13% and 16% in low mid elevation counties, respectively. Standing dead biomass decreased by 9.2% and 2.8% in low and mid elevation counties, respectively. Downed dead wood increased by 22% in low elevation counties and decreased 50% in mid elevation counties. Annualized growth and harvest were both higher (16% and 58% respectively) in mid elevation than low elevation counties, while annualized mortality was 25% higher in low elevation counties. Annualized growth in low elevation counties was negatively correlated to sea level rise rates, and positively correlated to number of storms, illustrating tradeoffs associated with different climate change drivers. Overall, our results illustrate the vulnerability of US coastal low and mid elevation forests to climate change and sea level rise, with indications that the complexity and rate of change in associated ecosystem functions (growth, mortality, and carbon storage) within the greater social environment (agricultural abandonment) may increase.

Colorectal cancer (CRC) is commonly treated with intestinal resections that lead to colostomy, which can influence changes in eating habits. This study aimed to analyze energy and nutrient intake, diet quality, and food consumption based on the processing level in CRC patients after colostomy. A prospective study was carried out at three time points (T0–recent colostomy, T1–3 months after colostomy, and T2-6 months after colostomy). Food intake was assessed by 24-hour dietary recall. Macro-micronutrient consumption, the Brazilian Healthy Eating Index-Revised (BHEI-R), and food consumption according to processing level by NOVA classification (raw or minimally processed, processed, and ultra-processed foods) were estimated. Generalized estimating equations were used to compare the food intake variables with time points. Of the 46 patients, 52.2% were women, and the mean age was 60.6±12.2 years old. There was a change in food consumption over time, with an increase in energy consumption (kcal and kcal/kg), lipids, and sodium, in addition to a reduction in some nutrients such as protein (g and g/kg), fiber, vitamin B1 and C and phosphorus. Regarding the key outcomes, BHEI-R and NOVA classification showed a poor diet quality with a reduction in total index (p = 0.022), raw food (p = 0.001), total fruits, and whole fruit consumption (p = 0.001), and an increase in sodium (p = 0.001) at 3 and/or 6 months after colostomy concomitant an increase in ultra-processed food (p = 0.015). Nutritional counseling is essential in care, effective eating changes habits improvement of symptoms and nutritional status, besides avoiding potential cancer recurrence.

In recent years, Japan has experienced a significant increase in the number of foreign students and workers entering the country. This has resulted in a vast number of international patients in medical facilities. This shift emphasizes the immediate need for Japanese nurses who are both clinically proficient and culturally attuned. In response, our research developed and validated the Cross-cultural Competence Scale for Japanese Nurses (CCCSJN) to better equip nurses for diverse patient care. We conducted a cross-sectional study in Japan’s general hospitals using anonymous questionnaires with nurses and midwives. The scale, developed from data from 394 nurses, underwent both qualitative and quantitative evaluations to define its construct. We analyzed the data using exploratory factor analysis, criterion-related validity, internal consistency, and test-retest reliability, confirming the scale’s reliability and validity. The exploratory analysis revealed five factors: “cross-cultural understanding,” “cross-cultural communication ability,” “motivation for cross-cultural nursing,” “cooperation with multiple professions,” and “respect for foreign patients.” These factors explained 50.92% of the total variance. Cronbach’s α for the CCCSJN was 0.94, and the test-retest reliability correlation was 0.77. The construct validity, criterion-related validity, internal consistency, and test-retest reliability of the CCCSJN were verified. The CCCSJN can be used to assess the cross-cultural competencies of Japanese nurses and identify what skills need to be mastered, leading to improved cross-cultural competence and care.

Cellular therapy is a promising treatment option for Peripheral Arterial Disease (PAD). Different cell types can be used to regenerate and repair tissues affected by PAD. Many studies have proposed the use of stem cells, such as mesenchymal stem cells, or even mononuclear cells isolated from peripheral blood or bone marrow, to treat PAD. This paper reports a protocol of systematic review and meta-analysis that aims to identify the effects of stem cell treatment in patients with peripheral arterial disease. The search will be conducted in the following database: PubMed/MEDLINE, Clinicaltrial.gov, Scopus, Embase, Epistemonikos, Web of Science and Cochrane Library. Studies will be selected independently by two reviewers and will include all published randomized and non-randomized clinical trials. The data extraction will include studies population characteristics, type of treatment and main outcomes. We will assess the methodological quality of the studies using the Cochrane Risk of Bias 2.0 and Risk of Bias in Non-randomized Studies of Interventions. The certainty of the evidence will be rate using the Grading of Recommendations, Assessment, Development, and Evaluations. The findings will be presented in narrative summary tables and in a meta-analysis.

Aquaporin 1 (AQP1) is a key channel for water transport in peritoneal dialysis. Inhibition of AQP1 could therefore impair water transport during peritoneal dialysis. It is not known whether inhibition of AQP1 occurs unintentionally due to off-target interactions of administered medications. A high-throughput virtual screening study has been performed to investigate the possible binding of licensed medications to the water pore of human AQP1. A complete model of human AQP1 based on its canonical sequence was assembled using I-TASSER and MODELLER. The model was refined via the incorporation of pore water molecules from a high-resolution yeast aquaporin structure. Docking studies were conducted for the cytoplasmic domain of the AQP1 monomer against a library of all compounds listed in the British National Formulary (BNF), using the PLANTS software with the ChemPLP scoring function. The stability of the best docked conformations within the intrinsic water pore was assessed via short 15 nanosecond molecular dynamics (MD) simulations using the GROMACS-on-Colab utility. Of the 1512 compounds tested, 1002 docking results were obtained, and 198 of these conformations occupied a position within the intrinsic water pore. 30 compounds with promising docking scores were assessed by MD. The docked conformations for dopamine, gabapentin, pregabalin, and methyldopa were stable in these short MD studies. For furosemide and pravastatin, the MD trajectory suggested a binding mode different to the docking result. A small set of compounds which could impede water transport through human AQP1 have been identified in this computational screening study.

Unplanned extubation (UPE), defined as accidental removal of the endotracheal tube during mechanical ventilation or its replacement due to suspected obstruction or inadequate diameter, is considered the fourth most common adverse event in neonatal intensive care units (NICU). This study aimed to describe a systematic review and meta-analysis protocol that will identify and assess the effect of primary intervention measures designed to prevent UPE in NICU. A search will be carried out in the following databases: PubMed/Medline, EMBASE, Scopus, CINAHL, Cochrane Library, SciELO, and LILACS. Reviewers, in pairs and independently, will select the studies, perform data extraction and assess the methodological quality of the included studies using preestablished tools according to the type of study. The systematic review will provide evidence to present the main intervention measures used in the prevention of UPE during the care of critical neonatal patients. The systematic review and meta-analysis resulting from this protocol may provide important information regarding UPE in the neonatal population, which will help with decision-making and the implementation of safer clinical practices that focus on the reduction of adverse events, contributing to the improvement of service management and the safety of neonatal patients.

Published: January 2025

Both virtual reality and aromatherapy have shown promising impacts on the health and well-being of older adults. Aromatherapy has been reported to enhance immersive experiences during virtual reality programs. However, studies on the combined use and impact of virtual reality and aromatherapy for older adults have not been systematically reviewed. Therefore, this scoping review will identify existing types of virtual reality programs supported by various forms of aromatherapy and their outcome measures and results on the well-being of older adults. This review will be conducted in accordance with the Joanna Briggs Institute methodology or scoping reviews and will be reported in line with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews. The search strategy will encompass both published and unpublished papers. The databases to be searched are CINAHL, MEDLINE, Embase, Scopus, Web of Science, ACM digital library, IEEE Xplore digital library, Compendex, ProQuest, and Google Scholar. Two independent reviewers will perform title and abstract screening, full-text screening, and data extraction. Data analysis and synthesis will be discussed by the whole research team, mapped in the literature table and accompanied by a narrative summary. Scoping review data will be collected from publicly available articles; research ethics approval is not required. The findings will be disseminated through a peer-reviewed publication and conference presentations.

A Köz-gazdaság által dr. Nemeslaki András egyetemi tanárral, a BME rektorhelyettesével készített interjút egy olyan sorozat bevezetőjének szánjuk, ami a mérnökök üzleti és a közgazdászok technológiai tudásával foglalkozik. Az EU versenyképességi jelentései is világossá tették, hogy a gazdasági fejlődés tekintetében létfontosságú a két szakma közötti erőteljesebb párbeszéd, egymás teljesítményének ismerete, alkalmazása. Az új műszaki eredmények elterjesztéséhez korszerű üzleti modellekre van szükség és az üzleti modellek csak akkor lehetnek sikeresek, ha a műszaki innovációt támogatják. E cél elérésében az egyetemi szférának fontos szerepe van, ebbe szeretnénk bekapcsolódni.
