Health Care Utilization and Associated Economic Burden of Postoperative Surgical Site Infection after Spinal Surgery with Follow-Up of 24 Months

Background Surgical site infection (SSI) may lead to vertebral osteomyelitis, diskitis, paraspinal musculoskeletal infection, and abscess, and remains a significant concern in postoperative management of spinal surgery. SSI is associated with greater postoperative morbidity and increased health care payments. Methods We conducted a retrospective analysis using MarketScan to identify health care ut

Cost-Effectiveness of Device-Aided Therapies in Parkinson's Disease : A Structured Review

Background: Despite optimal dopaminergic treatment most patients in moderate to advanced stages of Parkinson's disease (PD) experience progressively increasing disabilities, necessitating a shift from oral medication to device-aided therapies, including deep brain stimulation (DBS), intrajejunal levodopa-carbidopa infusion (IJLI), and continuous subcutaneous apomorphine infusion (CSAI). However, t

RIFM fragrance ingredient safety assessment, butyl lactate, CAS registry number 138-22-7

The existing information supports the use of this material as described in this safety assessment. Butyl lactate was evaluated for genotoxicity, repeated dose toxicity, reproductive toxicity, local respiratory toxicity, phototoxicity/photoallergenicity, skin sensitization, and environmental safety. Data from read-across analog ethyl (L)-lactate (CAS # 687-47-8) show that butyl lactate is not expec

System-Level Access to On-Chip Instruments

Modern integrated circuits (ICs) contain thousands of instruments to enable testing, tuning, monitoring, and so on. These on-chip instruments must be accessed through the ICs’ life- time. However, when ICs are mounted on Printed Circuit Boards (PCBs), access from system-level is challenged due to complex system hierarchies with a multitude of interfaces. In this paper we enable access from system-

Graceful Degradation of Reconfigurable Scan Networks

Modern integrated circuits (ICs) include thousands of on-chip instruments to ensure that specifications are met and maintained. Scalable and flexible access to these instruments is offered by reconfigurable scan networks (RSNs), e.g. IEEE Std. 1687. As RSNs themselves can become faulty, there is a need to exclude and bypass faulty parts so that remaining instruments can be used. To avoid keeping t

Increasing importance of precipitation in spring phenology with decreasing latitudes in subtropical forest area in China

Climate warming has significantly advanced plant spring phenology in temperate and boreal biomes in the northern hemisphere. However, the response of subtropical forest phenology to climate change remains largely unclear. This study aimed to determine the spatiotemporal patterns of spring photosynthetic phenology in subtropical forests in China over the period 2002-2017 and explore its underlying

An automatic classification algorithm for submerged aquatic vegetation in shallow lakes using Landsat imagery

Submerged aquatic vegetation (SAV) is one of the main producers in inland lakes. Tracking the temporal and spatial changes in SAV is crucial for the identification of state changes in lacustrine ecosystems, such as changes in light, nutrients, and temperature. However, the available SAV classification algorithms based on remote sensing are highly dependent on field survey data and/or human interve

Numerical and experimental aspect of coherent lensless imaging

This thesis is devoted to the understanding, application, and extension of coherent lensless imaging methods for microscopy purposes. Particular attention is given to the Fourier transform holography and coherent diffractive imaging methods.These two methods share several properties such as the ability for singleshot imaging and their experimental geometries, but differ greatly in their reconstruc

The Impact of the Female Advantage in Education on the Marriage Market

In recent years, the traditional gender gap in educational attainment in favor of men has been reversed in many countries. This development may have far-reaching consequences for the family, challenging traditional patterns of union formation and potentially affecting marriage and fertility outcomes. I study the implications of the female advantage in education on family formation through changes

Multi-wavelength phase retrieval for coherent diffractive imaging

Phase retrieval is a numerical procedure concerned with the recovery of a complex-valued signal from measurements of its amplitude. We describe a generalization of this method for multi-wavelength data acquired in a coherent diffractive imaging experiment. It exploits the wavelength-dependent scaling of the support domain to recover separate reconstructions for each wavelength, providing new possi

Mapping of quick clay using sounding methods and resistivity in the Gota River valley

For a long time, the predominant method for detection of quick clay in Sweden has been to take undisturbed samples and to perform fall-cone tests on the clay in its undisturbed and remoulded state. In connection with a large stability investigation covering both sides of the Gota River, from the lake Vanern to the city of Gothenburg, the usefulness of CPTu and static pressure sounding for mapping

Cross laminated timber at in-plane beam loading – Comparison of model predictions and FE-analyses

The work presented concerns validation of a specific analytical model for Cross Laminated Timber (CLT) at in-plane beam loading conditions. The original model (model A) has previously been presented in the literature and is also suggested to be used as a basis for design equations for the next version of Eurocode 5. An improved version (model B) of that original model (model A), regarding basic as

Data quality quantification for time domain IP data acquired at a former waste deposit in Lund

Tests were done measuring resistivity and time domain induced polarisation using standard multi-core cable spreads and a special layout with separate cable spreads for transmitting current and measuring potentials. For both types of cables spreads both normal and reciprocal measurements were done in order to estimate the measurement errors. The tests were done on a former landfill in Lund in Swede

Determinants of health-related quality of life in a multinational systemic sclerosis inception cohort

OBJECTIVES: To evaluate health-related quality of life (HRQoL) and its determinants in a systemic sclerosis (SSc) multinational inception cohort. We performed a meta-analysis of data from individual countries, and compared the meta-analysis to individual country results by pooling data from each of the countries.METHODS: SSc patients within 2 years of disease onset were recruited from 5 countries
