Use of a “baby bottle” to allow a “better-than-nothing” death in older adults infected by COVID-19 in Quebec retirement homes – A case study

The COVID-19 pandemic has brought to the forefront profound questions surrounding dying and the concept of a “good death”. This qualitative case study, conducted in a health center in Quebec, Canada, severely affected by outbreaks during the pandemic's first wave, explores end-of-life care for older adults in retirement homes. Through thirty interviews with healthcare practitioners, researchers, and managers, we investigate the critical role of a pharmacological device referred to as the “baby bottle” in providing end-of-life care to older adults infected with COVID-19 in their homes. Drawing upon the boundary object framework, we examine the ambiguities surrounding the use of this device and explores its agency. In this unprecedented context, we argue that the device facilitated a form of death that could be described as “better than nothing”, embodying practitioners' efforts to provide some dignity to the dying person, by minimally controlling the distress and ensuring a connection between the dying person and the care team. Additionally, it served as a means of coping with the pandemic's intolerable aspects, such as the exclusion of frail older adults for the supposed common good. This study raises questions about the legitimacy and normalization of such compensatory measure within under-resourced healthcare systems for older people experiencing a loss of autonomy.

Hybrid multimodal fusion for graph learning in disease prediction

Graph neural networks (GNNs) have gained significant attention in disease prediction where the latent embeddings of patients are modeled as nodes and the similarities among patients are represented through edges. The graph structure, which determines how information is aggregated and propagated, plays a crucial role in graph learning. Recent approaches typically create graphs based on patients' latent embeddings, which may not accurately reflect their real-world closeness. Our analysis reveals that raw data, such as demographic attributes and laboratory results, offers a wealth of information for assessing patient similarities and can serve as a compensatory measure for graphs constructed exclusively from latent embeddings. In this study, we first construct adaptive graphs from both latent representations and raw data respectively, and then merge these graphs via weighted summation. Given that the graphs may contain extraneous and noisy connections, we apply degree-sensitive edge pruning and kNN sparsification techniques to selectively sparsify and prune these edges. We conducted intensive experiments on two diagnostic prediction datasets, and the results demonstrate that our proposed method surpasses current state-of-the-art techniques.

Modeling the impact of driving aggression on lane change performance Measures: Steering compensatory Behavior, lane change execution duration and crash probability

The current study aimed to investigate the influence of driving aggression on lane change behavior. Drivers belonging to three levels of aggressive driving styles (aggressive, moderately aggressive, and non-aggressive) participated in lane change experiments, and 232 lane change maneuvers were recorded. Steering behavior during lane change maneuvers was investigated using three steering performance measures, including the standard deviations of steering angle, steering reversal rates, and maximum steering swerve. Three separate generalized estimating equation models were developed to analyze the effects of aggressive driving behavior on the standard deviation of steering angle, steering reversal rates, and maximum steering swerve. A Weibull accelerated failure time model with clustered heterogeneity was developed to analyze the effect of aggressive driving behavior on lane change execution duration. Additionally, to model the crash probability during lane change, a random effects logistic regression model was developed. The findings indicate that aggressive and moderately aggressive drivers completed lane changes 59% and 38% faster, respectively, compared to non-aggressive drivers. This implies a propensity for aggressive and moderately aggressive drivers to execute lane changes more swiftly than non-aggressive drivers. Aggressive drivers increased their standard deviation of steering angle, steering reversal rates, and maximum steering swerves by 180%, 60%, and 62%, respectively, compared to non-aggressive drivers. This implies that aggressive drivers engaged in extreme steering behavior as a compensatory measure for their reckless driving in order to avoid a collision during lane change maneuvering. However, despite their vigorous compensatory steering behavior, the crash rate (number of crashes observed) increased by 5.10 and 2.83 times for aggressive and moderately aggressive drivers, respectively, compared to non-aggressive drivers. The findings have implications for developing driving assistance systems and lane change simulation models.

Association between weekend catch-up sleep and depression of the United States population from 2017 to 2018: A cross-sectional study

Insufficient sleep on weekdays has become a societal norm, and studies have shown that sleep deprivation increases the risk of depression. Although individuals often resort to weekend catch-up sleep (CUS) as a compensatory measure, the present evidence supporting its efficacy in mitigating the risk of depression is limited. This article attempts to explore the relationship between CUS and depression. In this study, a total of 5510 participants were included, characterized into two groups: nondepressed (n = 5051) and depressed (n = 459), with data extracted from the National Health and Nutrition Examination Survey (NHANES). Compared with people without CUS, those practicing CUS exhibited a significantly lower risk of depression (OR = 0.81, P = 0.048). In subgroup analysis, this reduction effect was only observed in males (OR = 0.70, 95 % CI 0.05 to 0.99, P = 0.04), middle-aged (>40, ≤60) (OR: 0.57, 95 % CI: 0.40 to 0.81, P = 0.002), married or living with parents (OR: 0.61, 95 % CI: 0.44 to 0.86, P = 0.004), groups with three or more family members (OR: 0.69, 95 % CI: 0.52 to 0.93, P = 0.01), and individuals without alcohol intake (OR: 0.24,95 % CI: 0.09 to 0.67, P = 0.006). Therefore, in the realm of depression treatment, doctors may consider advising patients to get adequate sleep on weekends as part of their overall treatment plan. At the same time, individuals can also choose weekend sleep as a proactive strategy for regulating their psychological status.

Flexible AC Transmission Using TSR By IJISRT

The project uses Thyristor Switch Reactance, or TSR, to achieve FACTS. When charging the transmission line, it is done when there is very little or no load at the receiving end. Due to the low load, the transmission line has minimal current flow, which highlights the shunt capacitance. The voltage at the receiving end increases two times more than the voltage at the sending end as a result of this voltage amplification, or Ferranti Effect. Shunt inductors are consequently automatically linked across the transmission line as a compensatory measure.

Повышение биопотенциала молоди муксуна Coregonus muksun сверхслабыми импульсными магнитными полями в условиях рыбоводного хозяйства

The results of a production experiment with juvenile muksun carried out at the Sob fish hatchery (Kharp village, Yamal-Nenets Autonomous Okrug) are presented. The purpose of the experiment, as an important element in the compensatory measure for the reproduction of valuable fish species, was to increase the biopotential of juveniles for their release into the Ob. For several days before hatching, the embryos were treated with ultra-weak pulsed magnetic fields in a specific frequency range. In the postembryonic period, control and experimental muksun juveniles were studied using morphometric and cytological-histological methods. It was established that the experimental juveniles during the entire growing period exceeded the control ones in most parameters, and before release into the Ob River for feeding, the weight of the experimental muksun fry significantly exceeded the weight of the control juveniles. When assessing the nature and degree of connection between morphometric parameters using cluster analysis, it was shown that by the time the experiment was completed, a higher correlation between traits was observed in the experimental juveniles, which is additional confirmation of its increased balance in the development process. The level of formation of the gonads of the reproductive system in the experimental individuals also exceeded the development of the gonads of the control ones - in terms of size and rate of sexual differentiation, number and cytometric indicators of germ cells. The data obtained allow us to consider it advisable to apply this approach in the practice of compensatory fish farming.

Abstract 11597: A Rare Cause of an NSTEMI: Left Main Coronary Artery Compression in a Patient With Pulmonary Hypertension

Background: Pulmonary hypertension has varying effects on cardiac function. Though uncommon, a dilated pulmonary artery can cause decreased coronary perfusion through extrinsic compression of the left main coronary artery (LMCA). While the most common presentation of LMCA compression is angina, acute coronary syndrome is rare. Case Summary: An 81-year-old female with a history of group 3 pulmonary hypertension presenting with neck and shoulder pain was found to have elevated cardiac biomarkers and EKG findings remarkable for isolated ST elevation in aVR with diffuse ST depressions in all other leads, consistent with a non-ST elevation myocardial infarction. Coronary angiography revealed left main coronary artery compression that was successfully intervened on with placement of a single drug eluding stent. Right heart catheterization was remarkable for evidence of severe pulmonary hypertension with a mean pulmonary artery pressure of 60 mmHg. Discussion: Given the patient’s past medical history, presenting symptoms, coronary and right heart catheterization findings the etiology of her acute coronary syndrome presentation was thought to be driven by left main coronary artery compression from pulmonary artery dilation. Pulmonary artery dilation in individuals with a history of pulmonary hypertension is common, with several modalities available to evaluate for this anatomic compensatory measure. Management for left main coronary artery compression in this patient population is percutaneous coronary intervention. Future studies to determine if routine screening for coronary compression in patients with pulmonary hypertension is needed.

The São Paulo State (Brazil) Ecological Fiscal Transfer: Distributive and environmental effects

To restore 12 million hectares of native vegetation in Brazil by 2030, aligning environmental policies with incentive measures is crucial. The Ecological Fiscal Transfer (known as Ecological ICMS in Brazil) allows states to redistribute the ICMS tax (similar to the Value Added Tax) revenue based on environmental criteria, likely motivating municipalities to take environmental action. São Paulo recently modified its ecological ICMS legislation, increasing the ICMS revenue distributed according to environmental criteria and introducing a new criterion for native vegetation cover. We assessed the impact of these changes on tax redistribution, considering three scenarios: the former rules (2021), the new rules (2025), and the new rules with 1.5 million hectares of vegetation restored (2042). While the pattern of ICMS distribution remained mostly unchanged, there were distributional effects. Some municipalities lost up to 5% of their initial revenue, while others with high socio-environmental importance doubled their revenues. Existing environmental criteria still lack incentives for local environmental policies. However, the new criterion for native vegetation cover could, with practical limitations, boost municipal revenue after restoring 1.5 million hectares. São Paulo's initiative to incorporate native vegetation cover into an Ecological Fiscal Transfer policy holds the potential to inspire similar tax-based environmental incentives worldwide. However, it must be adapted to motivate local governments to embrace restoration actions rather than serving primarily as a compensatory measure.

Do face masks undermine social connection?

AbstractMask mandates were commonplace around the world during the COVID‐19 pandemic and essential to slowing the spread of SARS‐CoV‐2. However, it is still unclear whether and how masks impact social bonding. Building on past research examining the effects of masking on emotion recognition and social perception, the current research examines the effect of masking on feelings of social connectedness. Three studies (total N = 177) using videotaped introductions of masked and unmasked peers and varied assessments of desire for social connectedness yielded no differences as a function of masking. Although participants reported more difficulty hearing masked (vs. unmasked) peers, masking did not significantly impact other facets of communication or perception related to social bonding. When participants filmed their own introductory videos (Study 3), results showed increased expressivity within the masked (vs. unmasked) conditions, perhaps as a compensatory measure to aid bonding. These findings speak to the resiliency of the human need to belong and belonging‐maintenance processes.

Carbon Balance of a Carboxylic Farm

Biological sequestration was studied as a compensatory measure to reduce greenhouse gas emissions. The article offers carboxylic farms set up on the example of the developed model in temperate climate. Its technological parameters were substantiated: plant species – Scotch pine (Pinus sylvestris), planting density – 8200 pieces/ha, life cycle – 40 years. At the end of the life cycle of a carboxylic farm, it is recommended to use the resulting wood in the pulp and paper industry, as well as the pyrolysis of mill culls with the release of carbonizates as a by-product fuel, sorbents for water purification and a composting structurer. The assessment of greenhouse gas emissions at all stages of the life cycle of a carbon farm showed that a significant part of the emissions occurs in the post-operational period and amounts to about 14 % of greenhouse gas uptake in CO2 equivalent.

Daily walking kinematic characteristics of the elderly in different residential settings: experimental study on Chinese community-living elderly and long-term nursing home residents.

Long-term nursing home (NH) care helps NH residents with their daily activities and improves their quality of life, but negatively affects their independent physical activities and increases the risk of dangerous events. Dangerous events in the elderly usually occur in the conversion of walking periods when forward striding has already happened, but the body has not yet entered a completely steady walking. Compare the gait characteristics in Chinese long-term NH residents and community-living elderly during the walking Transitional Period (TP) and Stabilization Period (SP). 32 long-term NH residents and 33 age- and sex-matched community-living elderly were recruited. The 30-Second Chair Stand Test (30-s CST), Timed Up and Go Test (TUGT), and Modified Falls Efficacy Scale (MFES) were used to assess their body function. The Xsens MVN BIOMECH system was used to collect and analyze the gait parameters of participants. Compared to community-living elderly, NH residents had fewer numbers of 30-s CST, took more time to complete TUGT, and lower MEFS scores. NH residents showed slower gait speed (P < 0.001), less peak hip flexion (P = 0.022) and extension (P = 0.003), knee internal rotation (P = 0.023), and ankle plantarflexion (P = 0.001) and internal rotation (P = 0.007) angles during walking. When walking progressed from TP to SP, NH residents showed increased ankle dorsiflexion (P < 0.001), decreased hip internal rotation (P < 0.001), and community-living elderly had increased hip extension (P = 0.005) angles. Chinese long-term NH residents had reduced lower extremities strength and postural balance, and higher fear of falling compared to community-living elderly. Their walking performance also showed high fall risk. Besides, long-term NH residents adopted a distal strategy to propel the body forward, which may be a compensatory measure to compensate for inadequate proximal joint control from forward walking to stable walking, and long-term NH residents have reduced postural stability during this process.

Morphological responses in peanut pod development to intercropping and nitrogen application rates

Short species in intercropping likely suffer from yield losses due to shading, but this can be mitigated through morphological changes and nitrogen (N) fertilization. However, little is known of the role of morphological responses to N supply and intercropping in peanut pod development. A two-year field experiment compared maize/peanut intercropping with single species cultivation at five N rates. Growth of branch and peg were measured at four growth stages for sole cropped and intercropped peanuts. Intercropped peanut promoted canopy elongation, which impeded the development of peanut pegs to the pods. Mature intercropped peanut plants increased the main stem height and the first pair of lateral branch length by 6.8% and 4.4%, respectively, but it decreased the total branch number, the node number of the main stem and the leaf area index by 4.6%, 5.9% and 12.7%, respectively. From anthesis to maturity, the peg biomass of the intercropped peanut firstly increased from 0.5 g to 1.0 g and then decreased to 0.6 g, which was much lower than that of sole cropping at corresponding phase (0.9, 1.8 and 1.6). The number of peg per plant was on average 49.0 in the mono cropping and 30.8 in the intercropping. Intercropping had negative effects on numbers of full pod, immature pod and total pod, but had no impact on the percentage of the full pod. N fertilization had little impact on aboveground morphological changes but significantly increased the full and total pod number of intercrops. Increasing N fertilizer from 0 to 270 kg ha−1 increased the full pod number of intercropped peanuts from 6.3 to 9.5 pods per plant, but the number decreased to 6.9 pods per plant when N was applied at 360 kg ha−1, while the total pod number was increased with N input from 9.4 per plant at N0 to 12.1 per plant at N270 and then decreased to 11.2 per plant at N360. The effect of N input on peg biomass was only significant at the pod setting stage. In general, the positive elongation in the intercropping could not compensate the failure in peanut pod development, but N fertilization could be considered as an effective compensatory measure which could promote pod setting and filling. This study provides a strategy for proper N fertilization beneficial for peanut’s pod development in intercropping.

Psychological Behavior and Compliance of the General Population with Facemasks during the COVID-19 Pandemic: Implications for the Future

Background: Globally people have succumbed to viral infections that posed a stupendous threat. Community wearing of facemask helped lowering the incidence of COVID-19. The objective was to determine the public opinion regarding prolonged mask-wearing practice, and to find out the behavioral differences as pertinent compensations for not wearing that may help combat pandemics because of emerging infections.&#x0D; Methodology: This cross-sectional study carried out in the outpatient departments of Military Hospital (MH) Rawalpindi, Pakistan from January to June 2021 after ethical approval. Participants selected by non-probability convenience sampling technique of different residential, economic and educational backgrounds, above 16 years of age, from both genders to give their opinion on a validated questionnaire, “Multidimensional face mask perceptions scale” with eight domains.&#x0D; Results: Among 175 participants, almost 81.7% participants were of the view that when they do not wear mask it is because facemasks get overheated and disrupt the breathing, 60.6% adopted compensation ways by avoiding people and 45.7% considered its wearing a hassle. Female participants felt more uncomfortable by disrupted breathing (p =0.029), male participants reflected about value of independence (p&lt;0.001), and participants from rural area thought a difficult access to get facemasks (p =0.003).&#x0D; Conclusion: The most likely reason for not wearing mask among participants was uncomfortable breathing. The other reasons includes adopting social distancing guidelines as a compensatory measure, finding facemask wearing practice a hassle, interference with freedom and access issues by rural population. Designing and implementing awareness sessions may halt such spread of pandemics because of emerging infections.

Infiltration well as compensatory measure of urban drainage: A financial analysis

The growth of cities generates a waterproofing of soils, causing much of the rain to seep off superficially. To remove this flow as soon as possible from the urban perimeter, urban drainage works are carried out. As in Brazil, conventional drainage techniques still predominate, in which the flow is transferred to the downstream points of the basin, these over time become inefficient, thus generating the need for the adoption of compensatory measures, among which we can mention the infiltration well. In view of the above this article aims to size an infiltration well for different areas of capture and perform a financial analysis of the construction of these devices. Four catchment areas (100 m², 250 m², 500 m² and 1000 m²) were adopted in the city of Aracaju/SE and for the sizing of the well was used a method adapted from Carvalho Júnior (2020). Wells with total depth ranging from 1.15 m to 6.10 m were obtained, and construction costs ranged from R$ 2,465.95 to R$ 8,697.53. Based on the results obtained, it is concluded that the sizing method applied is easy to apply, but implies larger wells, and finally, the replacement of concrete rings by another type of coating, can reduce the total cost for execution.

A Critical Analysis Comparing the Role of L1 in CLIL and Translanguaging

Mother tongue use in the classroom is an emerging practice combatting the old idea of achieving bilingualism through parallel monolingualism. As the discussion of the first language’s (L1) role within pedagogical contexts is still in its relative infancy, a critical analysis which compares how the pedagogical affordances of two recent L2 pedagogical approaches, Content and Language Integrated Learning (CLIL) and Translanguaging, influence language teachers’ pedagogical choices will contribute to the current understanding of how educators clarify the role of L1. Besides its recency, both pedagogies are also chosen as the scope of this discussion because their aims are not solely to gain knowledge of the target language (TL). Funnelling the discussion with two empirical studies which represents the typical application of these pedagogies, this essay found that L1 has three types of facilitating roles, namely class and task management, scaffolding the target language production, and conceptual clarification. A clear distinction between these two pedagogies is established: while CLIL teachers always prioritise TL and treats L1 as a compensatory measure, Translanguaging teachers are authorised to mobilise a wider range of communicative resources rooted in the learners’ mother tongue. This essay recommends further exploration on the role of L1 across other pedagogies to better empower educators in actively and judiciously employing the inevitability of students’ L1 in the classroom to their advantage.

Przestępstwo uchylania się od wykonania środka kompensacyjnego (art. 244c Kodeksu karnego) – ocena zasadności wprowadzenia regulacji

The purpose of this article was to assess the legitimacy of introducing Article 244c into the Criminal Code. It provides for the possibility of punishing a person who evades to fulfill of a compensatory measure in the form of a duty to redress damage or make restitution, ordered by the court in favour of the wronged party, for a crime prosecuted by public indictment. The regulation was analysed using the formal-dogmatic method, in order to verify whether the introduced provision is consistent with other solutions of criminal law and whether it does not contain any constructional errors. As a result of this analysis, it was concluded that this regulation cannot be reconciled with the nature of redress damage as a compensatory measure. Overly far-reaching penalisation has led to excessive differentiation of the effects of imposing the duty to redress damage on the perpetrator as a compensatory measure and as an effect of allowing a civil action and has led to many systemic inconsistencies related to the imposition of the duty to redress damage in criminal law. The regulation itself, on the other hand, is not very precise and does not properly define when the offender’s fulfilment of the elements of this criminal act occurs, which is its fundamental error.

Optimizing safe evacuation in mines: A method for selecting compensating measures based on microclimatic safety constraints during ventilation reversal

The article describes a method of selecting measures that should make life safe for people during evacuation through ventilation shafts under the influence of cold air during main fan reversal. The approach is based on the allocation of dangerous sections of the evacuation route and the application of compensatory measures to ensure a comfortable stay for miners in these areas. The need to introduce a compensatory measure for each area considered is determined by the condition that the time a miner stays in this zone is greater than the time during which the microclimatic parameters of the air reach unacceptable safety levels. A principle has been proposed for introducing the least resource-intensive and financially-intensive measures based on the actual need to remove miners from the mine in a given time. The developed method and the underlying approach are applicable to mine ventilation systems of any type.

Transgender Persons and Affirmative Action: Answering the Why and the How

Justice Radhakrishnan began his judgement in the landmark Indian case of NALSA v Union of India, with an observation on the society’s moral failure being exhibited by its exclusion of the transgender community and its inability to understand their pain. The division bench judgement unanimously stated, inter alia that reservations be opened up for the transgender community by declaring them as socially and educationally backward. In the years since this judgement, however, there have barely been any State actions in India to implement the judgement in its spirit. The Transgender Persons (Protection of Rights) Act, 2019, a statute passed to further the ideals of protecting the interests of the transgender community was met with resistance and protests from the transgender community itself. The absence of reservation provisions in the Act was one of the many grievances raised by the activists. India’s Union cabinet has recently approved a cabinet note to include transgender persons within the ‘Other Backward Communities’, a move to open up the reservations in education and employment to transgender persons. Here, I look at the dichotomy between the acceptance of transgender persons in the early local Indian community practices and the discrimination that came with the colonisation and western mores. I attempt to understand the use of contemporary legal tools, like reservations as a compensatory and corrective measure for the aforementioned discrimination. While examining the adequacy of reservations as a measure, I look at the possibilities of potential Affirmative Action policies that go beyond the traditional state mandated reservation policies in India. I also intend to learn from existing Affirmative Action policies for the transgender community in the United States and the United Kingdom to provide suggestions that can benefit the community in India.

Unstated impacts of the green energy industry on the habitat of a coastal delphinid: Turbid‐turbulent wakes induced by offshore wind turbine foundations

Abstract Offshore wind farms (OWFs) are a green energy solution to reducing CO2 emissions, but often encroach on major habitats of coastal delphinids. Clustered OWF construction in shallow waters may have cumulative negative impacts on coastal delphinids and marine ecosystems. Although the impacts of piling noise have been discussed extensively, the potential impacts of oceanographic alterations induced by wind turbine foundations are rarely discussed. Two OWFs were constructed near the core habitat of a critically endangered subspecies of humpback dolphin (Sousa chinensis taiwanensis) in the eastern Taiwan Strait. Turbid‐turbulent wakes induced by wind turbine foundations were inspected using Landsat images. Sighting rates of the humpback dolphin that were obtained from boat‐based line‐transect surveys near the northern OWF (OWFn) since the late 2000s were examined. Indicators of surface turbidity were used to highlight turbid‐turbulent wakes extending in the direction of the main current. Sighting rates of the humpback dolphins near the OWFn have been declining since the 2000s, but decreased significantly after the OWFn was constructed and began operating. The long‐term decline in sighting rates implies an alarming decline in the population size of humpback dolphins. Decreased sighting rates after the OWFn installation indicate the reduced utilization of a once‐important habitat. Offshore wind farm construction may influence prey abundance and composition and cause acute stress from piling noise; operational noise may mask the chorus of prey fish and turbid‐turbulent wakes may disturb the benthic ecosystem. Site selection committees for future OWFs should avoid the habitats of coastal delphinids and areas subject to strong ocean currents. Ecological impact assessments for OWF projects should examine the impacts of turbulent wakes on benthic ecosystems and of acoustic disturbance on marine mammals. Long‐term environmental monitoring programmes are recommended, which can be funded by wind energy companies as a compensatory measure.

Pelvic incidence significance relative to spinopelvic risk factors for total hip arthroplasty instability.

Pelvic incidence (PI) is a position-independent spinopelvic parameter traditionally used by spinal surgeons to determine spinal alignment. Its relevance to the arthroplasty surgeon in assessing patient risk for total hip arthroplasty (THA) instability preoperatively is unclear. This study was undertaken to investigate the significance of PI relative to other spinopelvic parameter risk factors for instability to help guide its clinical application. Retrospective analysis was performed of a multicentre THA database of 9,414 patients with preoperative imaging (dynamic spinopelvic radiographs and pelvic CT scans). Several spinopelvic parameter measurements were made by engineers using advanced software including sacral slope (SS), standing anterior pelvic plane tilt (APPT), spinopelvic tilt (SPT), lumbar lordosis (LL), and PI. Lumbar flexion (LF) was determined by change in LL between standing and flexed-seated lateral radiographs. Abnormal pelvic mobility was defined as ∆SPT ≥ 20° between standing and flexed-forward positions. Sagittal spinal deformity (SSD) was defined as PI-LL mismatch > 10°. PI showed a positive correlation with parameters of SS, SPT, and LL (r-value range 0.468 to 0.661). Patients with a higher PI value showed higher degrees of standing LL, likely as a compensatory measure to maintain sagittal spine balance. There was a positive correlation between LL and LF such that patients with less standing LL had decreased LF (r = 0.49). Similarly, there was a positive correlation between increased SSD and decreased LF (r = 0.54). PI in isolation did not show any significant correlation with lumbar (r = 0.04) or pelvic mobility (r = 0.02). The majority of patients (range 89.4% to 94.2%) had normal lumbar and pelvic mobility regardless of the PI value. The PI value alone is not indicative of either spinal or pelvic mobility, and thus in isolation may not be a risk factor for THA instability. Patients with SSD had higher rates of spinopelvic stiffness, which may be the mechanism by which PI relates to THA instability risk, but further clinical studies are required.
