Published: April 2024

Background:
Primary total knee arthroplasty (TKA) aims to improve the level of capability (ability to perform valued life activities) associated with knee osteoarthritis (OA). However, some evidence suggests a substantial proportion of patients remain dissatisfied with their outcomes after this procedure. We sought to better understand the association between mental health, specifically symptoms of depression, with postoperative outcomes. Symptoms of depression are shown to be common among orthopaedic populations in general and can be briefly and conveniently evaluated using the Patient Health Questionnaire-2 (PHQ-2) in a less burdensome manner compared with longer mental health surveys. This study assesses the association between preoperative depressive symptoms (PHQ-2) and levels of capability at 6 weeks and 6 months after TKA.

Methods:
We conducted a prospective cohort study involving 114 patients with knee OA across five clinics in California and Texas scheduled for TKA. Participants completed a preoperative PHQ-2 and Knee Injury and OA Outcome Score for Joint Replacement (KOOS JR) survey at 6 weeks and 6 months post-TKA. We analyzed these data using bivariate and multivariable regression.

Results:
Preoperative PHQ-2 scores were significantly associated with lower KOOS JR scores at 6 weeks and 6 months post-TKA. Latino/Hispanic race was also associated with lower KOOS JR scores at 6 weeks. The association between preoperative depressive symptoms and level of capability after TKA were more pronounced at 6 months compared with 6 weeks.

Conclusion:
Preoperative symptoms of depression are strongly associated with reduced capability after TKA and can be screened for using the PHQ-2—a brief tool that can be feasibly incorporated into clinical workflows. User-friendly assessment of depressive symptoms can assist orthopaedic surgeons in identifying and addressing mental health at the outset during the management of knee OA.

Статья посвящена проверке психометрических характеристик русскоязычной версии методики «Шкала сочувствия к себе» К. Нефф. Кроме того, была поставлена задача – установить нормативные показатели для данной шкалы с точки зрения суицидального риска. Нормативная выборка состояла из 490 студентов вузов, клиническая выборка – из 146 пациентов кризисного стационара, у которых наблюдались суицидальные мысли. Для проверки структуры опросника и установления пороговых значений применялась модель современной теории тестирования для рейтинговых шкал. Было показано, что «Шкалу сочувствия к себе» целесообразнее использовать и интерпретировать по шести субшкалам и двум факторам: «позитивного» и «требовательного» самоотношения. Это инструмент, дающий надежные и валидные результаты, а нормативные показатели позволяют использовать шкалу для выявления суицидального риска у молодежи при скринингах и в клиническом сеттинге.

O Helicobacter pylori (H. Pylori) é uma bactéria Gram-negativa transmitida via fecal-oral que possui adesinas que colonizam a mucosa gástrica, ligando-se às células epiteliais e acometendo cerca de 50% da população mundial. Embora no Brasil essa seja uma infecção muito comum, evidencia-se a ausência de um perfil epidemiológico traçado nessa população. Objetivo: Determinar o perfil epidemiológico de pacientes que realizaram endoscopia digestiva alta em uma clínica privada no Alto Vale do Itajaí a partir de um estudo transversal prospectivo. Métodos: No presente estudo foi realizada uma pesquisa prospectiva para coleta de dados epidemiológicos e incidência de infecção pela H. pylori a partir de exames endoscópicos realizados em uma clínica de referência na microrregião do Alto Vale do Itajaí, Santa Catarina, Brasil. Esta pesquisa caracterizou-se por ser um estudo observacional analítico, com delineamento epidemiológico transversal do tipo inquérito, para verificação das condições socioeconômicas, sintomas e histórico de doenças do trato gastrointestinal dos pacientes. Resultados: Foram avaliados 850 participantes, com média de idade de 52,1 anos. A partir da realização do Teste de Urease, verificou-se 208 pacientes (24,5%) da amostra com resultado positivo para presença de H. pylori. Conclusão: Condições socioeconômicas, de moradia e de saneamento básico são consideradas variáveis epidemiológicas que influenciam na infecção por H. pylori.

Oil shale is quite widespread in the world. They are represented by both small oil shale occurrences and large deposits. At present, only a few oil shale deposits in Brazil, China and Estonia are being exploited. Given the decline in global oil production, oil shale is a promising source of energy in the future.
Oil shale contains hydrocarbon reserves that are significantly higher than those of natural oil and gas. According to exploration data, the resources of oil shale deposits in the world are enormous. Their potential resources are estimated at 650 trillion tonnes, while known resources reach 450 trillion tonnes. It is difficult to make a general assessment of global resources, as different countries use different methods to study them, taking into account the availability of reserves, the need, and the feasibility of their extraction and use.
When addressing environmental issues, it is necessary to take into account the fact that gas emissions and wastewater from oil shale processing facilities contain pollutants that have an increased environmental impact and harmful effects on the human body.

Background
Leptospirosis is a water-related zoonotic disease. The disease is primarily transmitted from animals to humans through pathogenic Leptospira bacteria in contaminated water and soil. Rivers have a critical role in Leptospira transmissions, while co-infection potentials with other waterborne bacteria might increase the severity and death risk of the disease.

Methods
The water samples evaluated in this study were collected from four recreational forest rivers, Sungai Congkak, Sungai Lopo, Hulu Perdik, and Gunung Nuang. The samples were subjected to next-generation sequencing (NGS) for the 16S rRNA and in-depth metagenomic analysis of the bacterial communities.

Results
The water samples recorded various bacterial diversity. The samples from the Hulu Perdik and Sungai Lopo downstream sampling sites had a more significant diversity, followed by Sungai Congkak. Conversely, the upstream samples from Gunung Nuang exhibited the lowest bacterial diversity. Proteobacteria, Firmicutes, and Acidobacteria were the dominant phyla detected in downstream areas. Potential pathogenic bacteria belonging to the genera Burkholderiales and Serratia were also identified, raising concerns about co-infection possibilities. Nevertheless, Leptospira pathogenic bacteria were absent from all sites, which is attributable to its limited persistence. The bacteria might also be washed to other locations, contributing to the reduced environmental bacterial load.

Conclusion
The present study established the presence of pathogenic bacteria in the river ecosystems assessed. The findings offer valuable insights for designing strategies for preventing pathogenic bacteria environmental contamination and managing leptospirosis co-infections with other human diseases. Furthermore, closely monitoring water sample compositions with diverse approaches, including sentinel programs, wastewater-based epidemiology, and clinical surveillance, enables disease transmission and outbreak early detections. The data also provides valuable information for suitable treatments and long-term strategies for combating infectious diseases.

Published: April 2024

Context
Exogenous use of potential organic compounds through different modes is a promising strategy for the induction of water stress tolerance in crop plants for better yield.

Aims
The present study aimed to explore the potential role of alpha-lipoic acid (ALA) in inducing water stress tolerance in mungbean lines when applied exogenously through various modes.

Methods
The experiment was conducted in a field with a split-plot arrangement, having three replicates for each treatment. Two irrigation regimes, including normal and reduced irrigation, were applied. The plants allocated to reduced irrigation were watered only at the reproductive stage. Three levels of ALA (0, 0.1, 0.15 mM) were applied through different modes (seed priming, foliar or priming+foliar).

Key results
ALA treatment through different modes manifested higher growth under reduced irrigation (water stress) and normal irrigation. Compared to the other two modes, the application of ALA as seed priming was found more effective in ameliorating the adverse impacts of water stress on growth and yield associated with their better content of leaf photosynthetic pigments, maintenance of plant water relations, levels of non-enzymatic antioxidants, improved activities of enzymatic antioxidants, and decreased lipid peroxidation and H2O2 levels. The maximum increase in shoot fresh weight (29% and 28%), shoot dry weight (27% and 24%), 100-grain weight (24% and 23%) and total grain yield (20% and 21%) in water-stressed mungbean plants of line 16003 and 16004, respectively, was recorded due to ALA seed priming than other modes of applications.

Conclusions
Conclusively, 0.1 and 0.15 mM levels of ALA as seed priming were found to reduce the adverse impact of water stress on mungbean yield that was associated with improved physio-biochemical mechanisms.

Implications
The findings of the study will be helpful for the agriculturalists working in arid and semi-arid regions to obtain a better yield of mungbean that will be helpful to fulfill the food demand in those areas to some extent.

Published: August 2009

AbstractThe production of nanofibers of bioactive glass by laser spinning is reported. The technique yields a great quantity of free‐standing fibers in the form of a mesh of disordered intertwined fibers. The method does not rely on chemical processing and does not need any chemical additive. It involves melting of a precursor material with tailored composition, which makes it possible to produce nanofibers from materials with which conventional melt drawing techniques cannot be used. Herein, the production of 45S5 Bioglass nanofibers is reported for the first time. The process is very fast (nanofibers of several centimeters are grown in a fraction of a second), without the necessity of post heat treatments, and no devitrification is observed as a result of the laser‐spinning process. The morphology, composition, and structure of the nanofibers are characterized and an assessment of their bioactivity is carried out by immersion in simulated body fluid. This technique provides a method for the rapid production of dense glass nanofibers that can be employed as bioactive nanocomposite reinforcement, as a synthetic bone graft to replace missing bone, or to produce 3D structures for use as scaffolds for bone‐tissue engineering.

Published: August 2009

AbstractMulti‐walled carbon nanotube (MWNT)‐sheet‐reinforced bismaleimide (BMI) resin nanocomposites with high concentrations (∼60 wt%) of aligned MWNTs are successfully fabricated. Applying simple mechanical stretching and prepregging (pre‐resin impregnation) processes on initially randomly dispersed, commercially available sheets of millimeter‐long MWNTs leads to substantial alignment enhancement, good dispersion, and high packing density of nanotubes in the resultant nanocomposites. The tensile strength and Young's modulus of the nanocomposites reaches 2 088 MPa and 169 GPa, respectively, which are very high experimental results and comparable to the state‐of‐the‐art unidirectional IM7 carbon‐fiber‐reinforced composites for high‐performance structural applications. The nanocomposites demonstrate unprecedentedly high electrical conductivity of 5 500 S cm−1 along the alignment direction. Such unique integration of high mechanical properties and electrical conductance opens the door for developing polymeric composite conductors and eventually structural composites with multifunctionalities. New fracture morphology and failure modes due to self‐assembly and spreading of MWNT bundles are also observed.
Biodegradable Polymer Crosslinker: Independent Control of Stiffness, Toughness, and Hydrogel Degradation Rate

Published: August 2009

AbstractHydrogels are being increasingly studied for use in various biomedical applications including drug delivery and tissue engineering. The successful use of a hydrogel in these applications greatly relies on a refined control of the mechanical properties including stiffness, toughness, and the degradation rate. However, it is still challenging to control the hydrogel properties in an independent manner due to the interdependency between hydrogel properties. Here it is hypothesized that a biodegradable polymeric crosslinker would allow for decoupling of the dependency between the properties of various hydrogel materials. This hypothesis is examined using oxidized methacrylic alginate (OMA). The OMA is synthesized by partially oxidizing alginate to generate hydrolytically labile units and conjugating methacrylic groups. It is used to crosslink poly(ethylene glycol) methacrylate and poly(N‐hydroxymethyl acrylamide) to form three‐dimensional hydrogel systems. OMA significantly improves rigidity and toughness of both hydrogels as compared with a small molecule crosslinker, and also controls the degradation rate of hydrogels depending on the oxidation degree, without altering their initial mechanical properties. The protein‐release rate from a hydrogel and subsequent angiogenesis in vivo are thus regulated with the chemical structure of OMA. Overall, the results of this study suggests that the use of OMA as a crosslinker will allow the implantation of a hydrogel in tissue subject to an external mechanical loading with a desired protein‐release profile. The OMA synthesized in this study will be, therefore, highly useful to independently control the mechanical properties and degradation rate of a wide array of hydrogels.
