The Functional Efficiency of Older Patients after Lumbar Spine Surgery, the Impact of Pain, and the Passage of Time: Tips for Care Providers.

Chronic back pain in adults is often a cause of absenteeism from work, limitations in social interactions, and difficulties in performing daily activities. This study aimed to check whether the functioning of everyday activities in elderly patients after neurosurgery improved over time compared to their condition before the procedure and whether there is a connection between fitness, self-esteem, and pain intensity. This was a cross-sectional study carried out using an anonymous survey. This study included patients over 60 years of age from the neurosurgical ward. The following scales were used to assess cognitive functioning, depression, functional status: basic and instrumental activities of daily living (IADL), back pain disability (QBPDS), pain intensity, and self-esteem. The level of independence in terms of IADL and QBPDS increased, and the intensity of pain decreased. Surgery reduced pain intensity from 8 ± 0.8 to 6.1 ± 1.4 points. The level of self-esteem (RSES) remained at a low level. The passage of time after neurosurgical treatment has a beneficial effect on reducing pain intensity and increasing independence in life activities. Daily physical activity and rehabilitation are important factors supporting the return to independence.

Dietary diversity and its association with changes in anthropometric indices of community-dwelling older adults in Tehran, Iran: a longitudinal study (2017–2021)

BackgroundDietary diversity refers to the consumption of a variety of foods or food groups over a given reference period, which is crucial for improving nutrition and overall health. This longitudinal study aimed to investigate the association between dietary diversity and anthropometric indices in community-dwelling older adults living in Tehran in 2017 and 2021.MethodsThe current study was conducted on 368 older adults [204 (55.4%) women and 164 (44.6%) men] over 60 years of age living in Tehran, who were selected by a systematic cluster sampling method at two-time points, 2017 and 2021. Anthropometric measures (weight, height, hip circumference, and waist circumference) were assessed with standard methods. The participants’ dietary intake was assessed by completing two non-consecutive 24-hour recalls, and dietary diversity score (DDS) was calculated based on Kant’s method. Statistical analysis was performed using R software by the mixed effect model method.ResultsThe mean DDS of the participants in 2017 (5.07 ± 1.20) was higher than that in 2021 (4.94 ± 1.09) (p < 0.05). DDS and dairy diversity score decreased significantly over time. After adjusting for confounders, there was an inverse relationship between the DDS and Body Mass Index (BMI) (B = -0.22; SE = 0.09), but the interaction effect of year × DDS (B = 0.19; SE = 0.10) was not significant (p = 0.06). However, there was a positive relationship between the DDS and A Body Shape Index (ABSI) (B = 0.00; p = 0.022), after adjusting for confounders, this relationship was no longer significant. Additionally, the interaction effect of year and DDS on the ABSI was not significant.ConclusionThe dietary intake and dietary diversity of older adult residents of Tehran declined dramatically with age, and a higher DDS was associated with improved anthropometric indices. DDS had an inverse relationship with general obesity in the studied participants, and the passage of time did not affect this relationship. The DDS can be used as a predictive index and is a powerful tool for investigating changes in nutritional status in longitudinal studies of old age. However, longer-duration studies are needed to obtain more conclusive results.

Effects of environment and human activities on rice planting suitability based on MaxEnt model.

Rice is one of the major food crops, and the study of suitable planting areas for rice plays an important role in improving rice yield and optimizing the production layout. This study used Maximum Entropy (MaxEnt) model to simulate and predict the distribution of suitable rice planting areas in China from 1981 to 2020 by combining the climate, soil, and human activities, analyzed the spatial and temporal changes of suitable rice planting areas in China, and determined the main factors affecting rice planting suitability. The results indicated that the main factors influencing the distribution of suitable planting areas for rice in China were gross domestic product (GDP), population density (Pop), and annual sunshine duration (Sun), with human activities playing a dominant role. The high suitable planting areas of rice were mainly distributed in Hubei, Hunan, Jiangxi, Anhui, Guangdong, southeastern Sichuan and western Guizhou. The total suitable planting areas for rice were 346.00 × 104 km2, 345.66 × 104 km2, 347.01 × 104 km2, and 355.57 × 104 km2 from 1981 to 1990, 1991 to 2000, 2001 to 2010 and 2011 to 2020, respectively. With the passage of time, the area of unsuitable areas for rice gradually decreased, and the area of medium suitable areas increased, with large changes in the area of high- and low-suitable areas. Moreover, due to the transfer of a large number of rural laborers to the cities in recent years, the tension between people and land caused by the population explosion has led to the increasing impact of Pop on rice suitable areas and the relatively weakening of the impact of GDP on rice production interventions. The results can be used to provide scientific evidence for the management of rice cultivation and food production safety, with a view to reducing the impacts of climate change on agricultural production in the context of global climate change.

EXPERIMENT TO DETECT THE ABSOLUTE VELOCITY OF EARTH IN THE UNIVERSE

A number of experiments have been carried out to measure the velocity of earth in the space but absolute velocity of earth could not be detected. One of the most famous Michelson and Morley experiment was conducted in the year 1887 to detect the motion of earth with reference to luminiferous aether a supposed medium permeating space that was thought to be the carrier of light waves but unexpected results were obtained. The experiment has given negative results, MMX type experiments have been repeated so many times with steadily increasing sensitivity from 1902 to 1930 and more recently in the year 2009 by optical resonator but all the experiments confirmed the negative results of MMX. Albert Einstein submitted his special theory of relativity in the year 1905 and stated that there is no medium like aether for propagation of light waves and there is no absolute velocity in the universe, all the motions are relative. Relative velocity of earth has been measured by various methods and observations such as stellar parallax, position of stars and planets, satellite laser ranging, GPS and CMB radiation. Second postulate of STR states that velocity of light is constant in all inertial frames of reference, there is no effect of motion of source of light or observer on the speed of light. As the velocity of light is a universal Constant hence any velocity with reference to speed of light will be absolute velocity. On the basis of second postulate of STR absolute velocity of earth in the universe can be determined by experiment based on the laser light beams. A laser beam may be directed on the fixed screen and movement of laser spot due to motion of earth may be observed. The displacement of laser spot with passage of time may be observed to determine the velocity of earth. In the present article it is explained how the velocity of earth may be detected by measuring displacement of laser spot. The displacement of laser spot from its normal position will determine the absolute velocity of earth in the universe.

Urban transport during the COVID-19 pandemic: a case study of Poland

AbstractOngoing improvement in the quality of public transport calms and slows road traffic while causing desirable changes in the transport behaviours of residents and the urban structure of city centres. These efforts were thwarted by the outbreak of the COVID-19 pandemic, which resulted in a significant decrease in public transport ridership. Its scope varied with the passage of time and with the dynamics of the pandemic itself, which were significantly different for individual cities. This article undertakes an analysis of these changes in Poland and identifies factors describing public transport accessibility that may influence them. The novelty of this article is examining the correlation of changes in public transport ridership in 17 Polish cities caused by the COVID-19 pandemic with the presented range of factors and conducted longitudinal studies. A multiple regression analysis was made possible by collecting data describing various aspects of public transport and populations. The introduction of remote work and learning also had a noticeable impact in public transport ridership during this period. In some sectors and fields, they have proven to be at least as efficient, but less expensive than their traditional forms, which suggests that they may have an impact on reducing the public transport ridership after the end of the pandemic.

Determinants of carbon sequestration in thinned forests

Given global climate change and the projected increases in the greenhouse effect, enhancing the carbon storage capacity of forest ecosystems is especially critical. To fully realize the potential carbon sequestration, it is imperative to understand the drivers affecting carbon storage in forest ecosystems, particularly with disturbances that disrupt existing balance. In this study, we explored the effects of stem-only harvest at various thinning intensities on forest structure and carbon density in middle-aged natural secondary forests, located in the northern temperate zone. Carbon density included aboveground carbon density (ACD), soil organic carbon stocks (SOCD), and total carbon density (TCD), which was the sum of ACD and SOCD. We employed the random forest analysis method to identify significant variables influencing changes in carbon density. Structural equation modelling (SEM) was then used to determine the drivers of changes in forest carbon density. The results showed that moderate thinning (20 %–35 % trees removed), is an effective management practice for increasing the TCD in forests. Although heavy thinning (35.1 %–59.9 % trees removed) accelerated individual growth, it did not fully offset the carbon removed due to thinning. It is noteworthy that light thinning (0–19.9 % trees removed) not only reduced the species richness but also caused a significant number of tree deaths. Large live trees were an important direct determining factor of ACD, but not the only one. In addition, thinning indirectly influenced ACD by reducing canopy density and deformed tree density. The increase in dead tree density had an adverse impact on SOCD, and this phenomenon increased with the passage of recovery time. Conversely, greater thinning intensity enhanced SOCD. Moreover, TCD was directly influenced by tree height, large live trees, and stand density. Furthermore, thinning altered the conifer ratio, thereby influencing tree growth and indirectly controlling the TCD. We believe that this knowledge will be highly beneficial for successful forest management and enhancing the carbon sequestration capacity of forest ecosystems.

Peningkatan Estetika Kawasan Kampung Ketupat Samarinda Melalui Desain Sculpture

Kampung Ketupat, located in the District of Samarinda Seberang - Samarinda, has been a tourist destination since 2017. Kampung Ketupat is one of the old villages in Samarinda located along the Mahakam River, consisting of stilt houses made from ironwood. Many of its residents are artisans who make 'ketupat' (woven palm leaf pouches for rice) containers sold in Samarinda and the surrounding areas. As time passes, facilities such as sculptures in Kampung Ketupat gradually become obsolete both in terms of appearance and materials. Based on these problems, the Building Architecture Study Program - Samarinda State Polytechnic, through Community Service activities, provided a solution to the problem with the Kampung Ketupat sculpture design approach, which is more in line with the needs of the tourist area. The implementation method is direct observation in the field, the study of related literature, interviews with local community groups and communities, and design activities. The result of the activity is a complete working drawing that can be used as a reference in making new sculptures by the management of Kampung Ketupat. Apart from the sculpture's proportions being more monumental, the update includes a more modern and Instagrammable design form and lighting on several sides. The working drawings can be an important input for plans to improve the aesthetics of the Kampung Ketupat area.

POSTMODERNIST VIEWS OF TIME AND SPACE IN LITERATURE

Rejecting canonical narrative forms and ideas, postmodern literature presents a fresh perspective on the passage of time and geographical location. In contrast to the linear and cohesive representations of time and space expected in modernist literature, postmodernist works often embrace dislocation, fragmentation, and distorted timelines. Through metafiction, intertextuality, and non-linear tales, this study investigates how postmodern writers question traditional ideas of space and time. These methods show time as cyclical, irrelevant, or fluid, which disrupts the reader's perception of a steady, chronological development. Similarly, postmodern literature frequently portrays space as hyperreal, fragmented, or disjointed, reflecting a world where the lines between the tangible and the abstract are increasingly blurred. This study analyses seminal postmodern works to see how these changed views of space and time fit into a more extensive critique of postmodern reality, identity, and meaning stability. According to the results, postmodern literature does more than make us rethink the passage of time; it also prompts us to wonder what it means to exist.

Improvements in Noise Symptoms, Forgotten Joint Scores, and Functional Outcomes With Greater Time Following Total Knee Arthroplasty

BackgroundTotal knee arthroplasty (TKA) is an impactful procedure with goals that include pain reduction and improved function, with low levels of prosthesis awareness. The purpose of this study was to determine if patients reported prosthetic noise and noise-related symptoms diminished over the course of time after TKA. MethodsThis study was a single institutional, retrospective study of patients who underwent primary unilateral TKA from 2018 to 2021. The TKAs were performed by four high-volume, fellowship-trained arthroplasty surgeons. Patients had similar baseline characteristics. Patients completed a survey consisting of four Likert scale questions related to prosthetic noise generation, the Forgotten Joint Score, and the Knee Injury and Osteoarthritis Outcome Score-Joint Replacement. Data were compared between patients who had undergone TKA one to two years earlier (N = 305) and those who had TKA three to four years prior to evaluation (N = 177). ResultsAfter more time with TKA, patients had significantly lower reports of hearing noise (31.1 versus 43.6%; P = 0.009) and feeling prosthetic noise-related symptoms (28.2 versus 40.3%; P = 0.010). Furthermore, after more time from TKA, patients had significantly higher satisfaction regarding noise-generation (65.5 versus 50.2%; P = 0.012), postoperative Knee Injury and Osteoarthritis Outcome Score-Joint Replacement scores (80.9 versus 75.9; P = 0.005), and Forgotten Joint Scores (65.4 versus 53.8; P < 0.001). ConclusionsAs more time passes after TKA, patients observe less prosthetic noise generation and have lower levels of prosthesis awareness and greater satisfaction than those who had surgery more recently. It is unclear whether these differences represent real improvement or acclimation to noise over time.

Palmoplantar Pustulosis: Therapy Update

Palmoplantar pustulosis is a variant of psoriasis and a chronic skin disorder in which pruritic pustular eruptions appear on the palms and soles. It is thought to arise from a variety of genetic and environmental factors, is limited in prevalence, and has proven quite difficult to treat. The symptoms it inflicts on those affected are quite debilitating and the treatment landscape is constantly evolving, thus emphasizing the need for updates of the literature as time passes. Current treatments include topical agents, oral therapies, and phototherapy, amongst other treatments. In this systemic review, we explore newer literature from 2015 to 2022 on various treatment regimens for palmoplantar pustulosis. J Drugs Dermatol. 2024;23(8):626-631.&nbsp; &nbsp;&nbsp; doi:10.36849/JDD.doi:10.36849/7612R1.

Time Flies at Work: How Work Design Shapes the Experienced Passage of Time

O Presente sob a forma das “tarefas infinitas” da herança e das realidades futuras da Zona Oriental de Lisboa

The contemporary city is covered with legacies as “infinite tasks”, which require critical and historical (re)knowledge, foreseeing its future transformation and adaptation. The Eastern Area of Lisbon (EAL) performs a case study of urban transformation, where critical, historical and affective interpretations of the passage of time over the territory come together in the present.

Research on the Composition and Socialvalue of Gongs and Drums in Huaihe River Basin of Anhui Province

The traditional Chinese folk instrumental music, gongs and drums, once flourished in southern China. The gongs and drums of Huaihe River basin in Anhui province were mainly distributed in Chizhou generation. The art of folk music originates from the life of the people. Relying on the unique historical, geographical and cultural environment, it presents a unique musical style to the audience. As an expression of ancient Chinese classical melody, it has continuously enriched and absorbed many excellent local culture and civilization achievements with the passage of time, and has exerted a profound influence on promoting the progress of Chinese traditional culture. Therefore, an in-depth exploration of its roots can enable us to more comprehensively understand and grasp the essence of this Great China culture with a long history of inheritance.

Aging, Age-Related Diseases, and the Zebrafish Model

The entrance of cells into a permanent state of cell cycle arrest with the ability to resist apoptosis is termed “cellular senescence”. The accumulation of senescent cells within the body can lead to tissue aging and the dysfunction of organs. Whether due to external stressors or the passage of time, aging is an inevitable process that afflicts every living being. Current studies that investigate aging rely on the use of cells or rodent models. Although cells present a cost-effective and quick way to analyze aging, they lack the complexity of whole-body systems and therefore require the use of an in vivo model post-in vitro assays. The zebrafish, Danio rerio, presents a cost-effective model with quick development and large numbers of offspring. These fish share 70% similarity of their genes with humans, including genes known to be associated with human diseases, such as those diseases of aging and/or senescence, like Alzheimer’s disease. Major tissues and organs of humans are also found in these fish, and therefore, zebrafish can serve as a useful model when studying diseases, aging, Alzheimer’s disease, and other disorders. In this review, we will discuss some of the major senescence biomarkers and detection methods, as well as discuss how zebrafish models can be used for the study of aging and age-related disorders.

Sleep consolidation potentiates sensorimotor adaptation.

Contrary to its well-established role in declarative learning, the impact of sleep on motor memory consolidation remains a subject of debate. Current literature suggests that while motor skill learning benefits from sleep, consolidation of sensorimotor adaptation (SMA) depends solely on the passage of time. This has led to the proposal that SMA may be an exception to other types of memories. Here, we addressed this ongoing controversy in humans through three comprehensive experiments using the visuomotor adaptation paradigm (N=290, 150 females). In Experiment 1, we investigated the impact of sleep on memory retention when the temporal gap between training and sleep was not controlled. In line with the previous literature, we found that memory consolidates with the passage of time. In Experiment 2, we used an anterograde interference protocol to determine the time window during which SMA memory is most fragile and, thus, potentially most sensitive to sleep intervention. Our results show that memory is most vulnerable during the initial hour post-training. Building on this insight, in Experiment 3 we investigated the impact of sleep when it coincided with the critical first hour of memory stabilization. This manipulation unveiled a benefit of sleep (30% memory enhancement) alongside an increase in spindle density and spindle-SO coupling during NREM sleep, two well-established neural markers of sleep consolidation. Our findings reconcile seemingly conflicting perspectives on the active role of sleep in motor learning and point to common mechanisms at the basis of memory formation.Significance statement While there is compelling evidence that sleep improves declarative memory, its role in the consolidation of motor memories remains a long-standing debate. For example, it is currently established that sensorimotor adaptation (SMA) consolidates with the passage of time, irrespective of sleep. This has led to the proposal that SMA may be an exception to other types of memories. Our findings indicate that SMA memories may indeed consolidate with both the passage of time and sleep, depending on the proximity between training and bedtime. Our work sheds light on this controversy and points to the existence of common mechanisms supporting consolidation across memory domains. Furthermore, it may impact rehabilitation programs, expediting motor injury recovery by aligning training sessions with sleep.

A community-based study of the impact of trauma exposure on school-aged children's self-concept and improvements following TF-CBT

BackgroundExperiencing trauma in childhood has been associated with more severe psychopathology and a greater risk of engaging in harmful behavior later in life. Traumatic exposure can also erode a child's self-concept. Negative self-concept has been associated with shame, self-doubt, and helplessness in the face of adverse experiences. Trauma-Focused Cognitive Behavioral Therapy (TF-CBT) is an evidence-based model for children; however, research on its effectiveness in improving children's self-concept is limited. ObjectiveTo investigate the impact of trauma on school-aged children's self-concept and improvements following TF-CBT. Participants and settingA demographically diverse sample of trauma-exposed school-aged children referred to community-based agencies in Canada and a normative sample of school-aged children randomly selected from the general population in the United States. MethodA longitudinal design was used to assess trauma-exposed children's self-reported self-concept using the short-form Tennessee Self-Concept Scale – Second Edition (TSCS:2; Fitts & Warren, 1996) prior to and following TF-CBT. ResultsTrauma-exposed children had a significantly more negative mean self-concept compared to that of the normative sample. Improvements following TF-CBT – and not the passage of time alone – were found with gains maintained six months post-therapy. ConclusionsSchool-aged children awaiting treatment at community-based agencies are likely to hold clinically concerning negative views of themselves. TF-CBT was effective in significantly improving their self-concept with continued and lasting improvements observed after the therapy had been completed.

The investigation of the characteristics of inflammatory factors and cardiac enzymes in children with Covid-19 hospitalized with the initial manifestation of fever without other symptoms hazrat Ali-Asghar Hospital in Tehran in 2018-2019.

The prevalence of asymptomatic fever among children is high and may be confused with fever caused by corona. The purpose of this study is to investigate the characteristics of inflammatory factors and cardiac enzymes in children with Covid-19 hospitalized with the initial manifestation of fever without other symptoms. In this descriptive-analytical cross-sectional study, all 200 children with positive Covid-19 were hospitalized in Hazrat Ali-Asghar Hospital in Tehran between 2018 and 2019. For gathering data, clinical records and demographic information of patients were noted in the made-researcher's checklist and the collected data were analyzed using SPSS software version 24. It was found that the relationship between the degrees of fever of the patients with the number of platelets was also inverse and significant. In addition, there was a significant relationship between the degree of fever of the patients and the LDH number, ALT number and segment and lymphocyte percentage of the patients. In addition, it was found that the passing time of fever has a significant relationship with ALT and ESR in such a way that with the passage of time, there is a higher probability of seeing an increase in ESR, but in the case of ALT, it increases in a shorter period of time and decreases more after the passage of time. According to the results of the present study, in case of suspected to Covid and fever in patients, along with other tests, AST, ALT, D-dimer, and CKMB can be used to diagnose Covid, in such a way that in Covid, AST is probably normal and mentioned other tests can be higher than normal.

Coupling coordination degree of healthcare resource supply, demand and elderly population change in China

ObjectTo analyze the trend of the coupling and coordination of the supply and demand of healthcare resources between the elderly population and healthcare resources in China during the period of 2012–2022, to reveal the impact of the growth of the elderly population on the relationship between the supply and demand of healthcare resources, and to put forward suggestions to improve the coupling and coordination between the supply and demand of healthcare resources and the elderly population, in order to cope with the challenges of an aging society.MethodsBy obtaining relevant data from authoritative data sources such as China Statistical Yearbook, Health and Health Statistics Yearbook, and the Chinese government website from 2012 to 2022, we constructed a comprehensive measurement index for the three systems of elderly population, healthcare resource supply, and healthcare resource demand; Using the entropy value method to assign weights to the indicators, combined with the coupling coordination degree model, to reveal the changes of the elderly population change and the supply and demand of medical and health resources; using ArcGIS technology, to study the spatial characteristics of the elderly population change and the supply and demand of medical and health resources.ResultsFrom 2012 to 2022, the supply and demand of healthcare resources and the variation of the elderly population in China show a continuous growth trend, and the comprehensive development level of the system gradually climbs from a low level to a high level. The fluctuation of coupling degree and coordination degree rises, although the coordination degree has always been lower than the coupling degree, but the distance between the coordination degree and the coupling degree gradually narrows with the passage of time. The coordination degree between population aging and medical and health resources development shows spatial heterogeneity in China, with the eastern region significantly higher than the western region/.ConclusionsThe coupling degree between population aging and healthcare resource supply and demand in China from 2012 to 2022 shows a general upward trend from low coupling to medium-high coupling, but it is worth noting that even though the degree of coupling increases, the degree of coordination is still relatively lagging behind, suggesting that the government and relevant departments need to pay more attention to coordinated allocation and management of healthcare resources. At the same time, the spatial differences in the degree of coordination among provinces suggest that future policymakers should take regional differences into full consideration in policymaking and sustainable development.

Concerted action agreements, corporate innovation, and financial market outcomes: A pre-registered report

This pre-registered study aims to investigate whether and how concerted action agreements enhance corporate innovation and create financial value. Based on theoretical analysis and numerous case studies, we expect to find that concerted action agreements significantly improve corporate innovation. The channels are at least two folds. First, by shielding entrepreneurs from short-term market pressure and enhancing their job security through enhancing their control rights, concerted action agreements spur long-term projects such as innovation. Second, through transferring control rights to entrepreneurs, concerted action agreements also strengthen entrepreneurs' stewardship role, which in turn mitigates agency problems and stimulates innovation. We further test the economic consequences of concerted action agreements and we expect to document that the agreements have a positive influence on firm performance and financial market valuation through enhanced corporate innovation. We also predict that because short-term market pressure and agency costs are high for high-tech firms due to information asymmetry, and because innovation is especially important for high-tech firms, concerted action agreements are most beneficial for high-tech firms. Finally, we predict that as time passes, the positive effects of concerted action agreements may diminish.

Analysis of Urban Form Dynamics in The Suburbs of Surakarta City 2013-2023

Urban Form has become necessary for city planning management to see the sustainability of a city. A better understanding of different urban forms is imperative to facilitate the evolution of cities towards a more sustainable urban development trajectory in the future. The study aims to analyze the dynamics of urban form and the changes in land cover within the peri-urban area of Surakarta City, which is directly influenced by the development of Surakarta City. The analysis was conducted from a landscape ecology perspective, employing a spatial metrics approach at the landscape level to assess the dynamics of urban form using quantitative descriptive, including a spatial approach. A similar approach was adopted at the class level in order to examine the dynamics of land cover changes. The results of the image analysis were validated using the Kappa index, yielding an image accuracy level of 0.86 (86%). The results of this study show that the urban form in the peri-urban area of Surakarta City tends to move towards a compact urban form. Meanwhile, each land cover, vegetation, and water body become increasingly fragmented, with areas becoming narrower as time passes. Built-up and agricultural land are becoming more compact and concentrated along with development. In conclusion, the dynamics of urban form in the peri-urban area of Surakarta City tends to lead to compact urban form.
