Whole-brain fMRI signals are a subject of intense interest: variance in the global fMRI signal (the spatial mean of all signals in the brain) indexes subject arousal, and psychiatric conditions such as schizophrenia and autism have been characterized by differences in the global fMRI signal. Further, vigorous debates exist on whether global signals ought to be removed from fMRI data. However, surprisingly little research has focused on the empirical properties of whole-brain fMRI signals. Here we map the spatial and temporal properties of the global signal, individually, in 1000+ fMRI scans...

After decades of having the developed world's highest rates of unintended pregnancy, the United States finally shows signs of improvement. This progress is likely due in large part to increased use of highly effective long-acting reversible methods of contraception. These methods can be placed and do not require any maintenance to provide years of contraception as effective as sterilization. Upon removal, fertility returns to baseline rates. This article addresses advances in both software-improved use and elimination of barriers to provide these methods; and hardware-novel delivery systems and devices...

BACKGROUND: Surgical strategies to address deformities of the ankle and hindfoot in patients with Charcot arthropathy include the use of retrograde intramedullary nails and ring fixators. The literature has not shown superiority of one technique over the other. This study presents a single surgeon's case series of Charcot arthropathy patients treated with either a ring fixator or retrograde intramedullary nail to achieve tibiotalocalcaneal arthrodesis. METHODS: We performed a retrospective analysis of 27 consecutive patients with Charcot arthropathy who underwent a tibiotalocalcaneal arthrodesis using either a retrograde intramedullary (IM) nail (n = 16 patients) or a ring fixator (RF) (n = 11 patients) by a single surgeon...

BACKGROUND: Simultaneous acquisition of EEG and fMRI data results in EEG signal contamination by imaging (MR) and ballistocardiogram (BCG) artifacts. Artifact correction of EEG data for real-time applications, such as neurofeedback studies, is the subject of ongoing research. To date, average artifact subtraction (AAS) is the most widespread real-time method used to partially remove BCG and imaging artifacts without requiring extra hardware equipment; no alternative software-only real time methods for removing EEG artifacts are available...

INTRODUCTION AND OBJECTIVES: Due to its inert character and desired biocompatibility, titanium (Ti) implants have been universally accepted as safer alternatives to the previous conventional orthopedic hardware implants. However, a recent emergence of Type IV hypersensitivity reactions to Ti have displayed symptoms that include eczema, contact dermatitis, prolonged fever, sterile osteomyelitis, and impaired fracture and wound healing. The following case presents a patient with postoperative incision dehiscence and devascularization of cortical surfaces in contact with Ti hardware after undergoing a medial displacement calcaneal osteotomy and a first metatarsal-cuneiform arthrodesis...

Locking plate fixation is becoming more popular for fixation of lower extremity osteotomies. The present study evaluated locking plate fixation compared with screw fixation in the medial displacement calcaneal osteotomy procedure, measuring the outcomes and rate of hardware removal. The procedure was performed on 30 patients, 31 times, with 17 undergoing single screw fixation and 14 undergoing locking plate fixation. The return to activity was 6.87 ± 1.43 months, including some patients for whom running was their main activity...

Dual-view inverted selective plane illumination microscopy (diSPIM) enables high-speed, long-term, four-dimensional (4D) imaging with isotropic spatial resolution. It is also compatible with conventional sample mounting on glass coverslips. However, broadening of the light sheet at distances far from the beam waist and sample-induced scattering degrades diSPIM contrast and optical sectioning. We describe two simple improvements that address both issues and entail no additional hardware modifications to the base diSPIM...

BACKGROUND: Implant removal is a common procedure in orthopedic surgery which can be associated with many complications such as scar formation, hematoma, nerve injury, infection, and refracture. Indications for orthopedic implant removal have declined in recent years. Most studies have considered orthopedic hardware removal as an unnecessary procedure in the absence of severe complications such as nonunion. Some studies have reported the complications of orthopedic hardware removal to be 24% to 50% dependent on their types and locations as well as on other factors such as patient's condition and the orthopedist's experience...

INTRODUCTION: A surgical technique to widen the mandible is the mandibular midline distraction: the most common indications for mandibular midline distraction are severe mandibular anterior crowding, severe mandibular transverse deficiency, uni- or bilateral crossbite, impacted anterior teeth with inadequate space, and tipped teeth. Commonly used distraction devices can be divided into 2 systems: bone-borne distraction system appliance, dental-borne distraction systems. Each system has peculiar advantages, disadvantages, and different indications...

BACKGROUND: In stress-positive, unstable supination-external rotation type 4 (SER IV) ankle fractures, implant selection for syndesmotic fixation is a debated topic. Among the available syndesmotic fixation methods, the metallic screw and the suture button have been routinely compared in the literature. In addition to strength of fixation and ability to anatomically restore the syndesmosis, costs associated with implant use have recently been called into question. PURPOSE: This study aimed to examine the cost-effectiveness of the suture button and determine whether suture button fixation is more cost-effective than two 3...

BACKGROUND: Medial patellofemoral ligament (MPFL) reconstruction is one of several surgical procedures used to treat patellofemoral instability. Use of allograft tissue can preserve autogenous tissue and may be preferable in patients with connective tissue disorders or ligamentous laxity. Although there are successful reports in adults, it is unclear if the use of allograft tissue in MPFL reconstruction can restore patellofemoral stability in children and adolescents. QUESTIONS/PURPOSES: (1) Does allograft tissue in MPFL reconstruction in pediatric and adolescent patients restore patellar stability? (2) What complications were associated with allograft MPFL reconstructions in children and adolescents? METHODS: Between June 2012 and August 2015, one surgeon (NKP) performed 26 MPFL reconstructions in 23 patients with gracilis allograft for traumatic patellar instability...

BACKGROUND: Lead extraction using laser sheaths is performed mainly for cardiac implantable electronic device (CIED) infections. However, there are few reports concerning the management of CIED infections in Japan. METHODS AND RESULTS: Lead extraction procedures were performed in 183 patients targeting 450 leads (atrial leads: 170, ventricular: 181, implantable cardioverter-defibrillators (ICDs): 79, and coronary sinus: 20). One hundred twenty patients (65.6%) presented with pocket infections without the presentation of an endovascular infection...

Along with the increased frequency of implantation, the incidence of cardiac implantable electronic device (CIED) infection, which can have serious or fatal complications, has also increased. Although several successful conservative therapies for CIED infection have been reported, retained infected devices remain a source of relapse, which is closely related to a higher mortality rate. Presently, complete hardware removal is initially recommended for infected CIED patients, and indications for conservative therapy, including continuous administration of antibiotics, require careful consideration...

AIMS: Patients with diabetes are at increased risk of wound complications after open reduction and internal fixation of unstable ankle fractures. A fibular nail avoids large surgical incisions and allows anatomical reduction of the mortise. PATIENTS AND METHODS: We retrospectively reviewed the results of fluoroscopy-guided reduction and percutaneous fibular nail fixation for unstable Weber type B or C fractures in 24 adult patients with type 1 or type 2 diabetes...

Femoral and tibial shaft fractures are common injuries in the United States. Since their introduction, reamed intramedullary nails have become the treatment of choice for most of these fractures. However, delayed union and nonunion can complicate treatment in up to 10% of patients. Removal of interlocking screws, or dynamization, can promote fracture healing in cases of delayed union or nonunion. The efficacy of nail dynamization has been reported to range from 19% to 82%. This study was conducted to evaluate the efficacy of dynamization, identify the factors associated with its success or failure, and analyze the cost compared with exchange nailing...
