The risk for developing a periprosthetic joint infection (PJI) during bacteremia is unclear, except Staphylococcus aureus bacteremia. aim of this study was to examine the PJI and identify possible factors leading it.Patients with primary knee or hip replacement performed in tertiary care hospital between September 2002 December 2013 were identified (n = 14 378) followed up until 2014. Positive blood culture results period PJIs recorded. associated an episode confirmed from patient records....

This paper describes a receiver designed to meet the stringent power consumption requirements for sensor radio, which operates at 2.4-GHz ISM band with Bluetooth. To enable reusability of Bluetooth system, only slight changes are made in radio parameters. The symbol rate is decreased and increased modulation index removes energy maximum from channel center, enables low-complexity direct-conversion solution. speed requirements, this fabricated 0.13-/spl mu/m CMOS process. 3.4-mW demonstrator...

Prosthetic joint infection (PJI) treatment decisions are traditionally based on algorithms. There is, however, a lack of evidence to support the choice these Therefore, we aimed assess one-year survival after PJI revision and compared different surgical strategies in single-center setting.

A new semi-physical behavioral amplifier model to characterize the AM/AM conversion of a bipolar solid-state high power in mobile phone is introduced. The functional able copy low-voltage features real causing crossover distortion. Hence it gives an improved description nonlinearity Class AB amplifiers widely used phones employing linear modulation scheme. accompanied by AM/PM function complete model. utilized communication system studies investigate increase common channel and adjacent...

Low end extension (LEE) for Bluetooth is a technology to solve simple mismatch. There are several small devices that could add value by having wireless radio connection mobile terminal but cannot bear the power consumption and cost associated with Bluetooth. However, terminals scheduled have as short-range solution. LEE tackles mismatch introducing minor additions chip in allows major savings radios embedded into devices. Examples of include sensors, toys, pens etc. This work presents...

Prosthetic joint infection (PJI) is one of the most devastating complications after total knee arthroplasty (TKA), and comorbidities increase risk. We examined whether a temporal change has occurred in demographics, especially regarding comorbidities, patients who have PJI were treated at our institution over 13-year study period. In addition, we assessed surgical methods used microbiology PJIs.Revisions (n = 384, 377 patients) due to performed between 2008 September 2021 identified. All...

<h3>Background</h3> The use of complementary and alternative medicine is high among children youth with chronic illnesses, including patients cardiac conditions. Our goal was to assess the prevalence patterns such presenting academic pediatric cardiology clinics in Canada. <h3>Methods</h3> A survey instrument developed inquire about current or previous products practices, indications, beliefs, sources information whether this discussed physicians. Between February July 2007, administered (or...

In clinical practice guidelines, the quality of available evidence is graded according to its reliability and quality. This study aimed evaluate research evidence, using levels in summaries 64 Finnish national evidence-based Current Care guidelines.Descriptive assessment.Electronic web-based guidelines Finland.The proportions with different (A-D).The had a total 2419 summaries. Of these, 532 (22.0%) were level A, 891 (36.8%) B, 808 (33.4%) C, 188 (7.8%) D. Most--that is, 81% C D dealt...

Cephalosporins are recommended as first-line antibiotic prophylaxis in total joint replacement surgery. Studies have shown an increased risk for periprosthetic infection (PJI) when non-cephalosporin antibiotics been used. This study examines the effect of on PJI.Patients with a primary hip or knee performed from 2012 to 2020 were identified (27 220 replacements). The outcome was occurrence PJI one-year follow-up. association between perioperative and examined using logistic regression...

A multicarrier Gaussian minimum shift keying (GMSK) modulator has been developed and implemented. The design contains four GMSK modulators, which generate modulated carriers at the specified center frequencies. Utilization of redundancy in stored waveforms reduces size trajectory look-up table to less than one-quarter original modulator. Conventionally, power ramping output level controlling are performed analog domain. novel digital ramp generator controller perform both burst dynamic...

The local wireless networking techniques are becoming more and popular in mobile terminals nowadays. Even so that LAN (e.g. IEEE 802.11b) Bluetooth solutions operating at the 2.4 GHz ISM band can be found same device. This enables new kind of usage possibilities applications from which most challenging ones, interoperability point view, those require simultaneous real-time operation over these links. One good example this service is a voice IP (VoIP) call WLAN to terminal with headset. In...

A novel functional nonlinear high power amplifier model for radio communication system simulations is used to study spectrum regeneration of a nonlinearly amplified /spl pi//4-DQPSK signal. Simulated adjacent channel has been compared measured results, and very good resemblance found. This together with satisfactory intermodulation behaviour in two-tone test simulation verifies that the proposed applicable accurate prediction simulations.

A multicarrier Gaussian minimum shift keying (GMSK) modulator with a 14-bit on-chip digital-to-analog (D/A) converter is presented. The design contains four GMSK modulators, which generate modulated carriers at the user-defined center frequencies. In wireless base stations, transmit signals are usually combined RF frequency after power amplification. combines in digital domain, thereby eliminating need for an antenna microwave combiner. new ramp generator and output power-level controller...

In conventional base station solutions, transmitted carriers are combined after power amplifiers (PAs). This paper describes an architecture in which four GMSK modulated signals the digital domain. saves a large number of analog components, many require production tuning. Consequently, expensive and tedious part manufacturing is eliminated. The proposed multicarrier modulator does not use I/Q modulator. Therefore difficulties adjusting dc offset, phasing amplitude levels between in-phase...
