Background: Bar stabilization during minimally invasive pectus excavatum repair (MIRPE) is critical to avoid dislodgement. Multiple techniques are described including stabilizers, wires, and sutures. This retrospective study compared bar movement and outcomes between existing techniques and ZipFix™, a biocompatible cable tie. Methods: Patients ≤20 years of age who underwent MIRPE with ZipFix between January 2021 and September 2022 were compared with historical controls who underwent repair by same surgeons between January 2018 and December 2020 using stabilizers or polydioxanone suture (PDS)...

Background: Endotracheal tube (ETT) occlusion is reported at a higher frequency among coronavirus disease-2019 (COVID-19) patients. Prior to the COVID-19 pandemic, literature examining patient and ventilator characteristics, including humidification, as etiologies of ETT occlusion yielded mixed results. Our study examines the relationship of humidification modality with ETT occlusion in COVID-19 patients undergoing invasive mechanical ventilation (IMV). Methods: We conducted a retrospective chart review of COVID-19 patients requiring IMV at a tertiary care center in New York from April 2020 to April 2021...

Carpometacarpal (CMC) joint dislocation is a rare injury that can be easily missed due to non-specific clinical signs and radiologic findings. We report a patient with an isolated and irreducible dorsal dislocation of the second CMC joint, which required an open reduction and K-wire transfixation. An extensor tendon was found to be interposed between the base and the trapezoid. K-wire removal was done after three weeks and following the removal of the wire, rehabilitation was started.

Tibial tubercle avulsion fractures are relatively uncommon fractures commonly seen in adolescent males. The treatment goal is to restore the extensor mechanism and to repair the articular surface. Although previous surgical techniques have been mainly screws or tension band wiring, there is a certain consensus on this. However, the choice of these surgical techniques largely depends on the surgeon. In our case, we utilized a suture anchor distal to the cannulated screw. This enabled us to use a smaller screw and cover the screw head completely with the patellar tendon...

Virtually all cells use energy-driven, ion-specific membrane pumps to maintain large transmembrane gradients of Na+ , K+ , Cl- , Mg++ , and Ca++ , but the corresponding evolutionary benefit remains unclear. We propose that these gradients enable a dynamic and versatile biological system that acquires, analyzes, and responds to environmental information. We hypothesize that environmental signals are transmitted into the cell by ion fluxes along pre-existing gradients through gated ion-specific membrane channels...

Diaphyseal fractures of the tibia is a common injury with an incidence of 16.9/100,000 population. Surgical treatment with intramedullary interlocking nail is the treatment of choice in closed diaphyseal tibial injuries. Removal of the nail is required in non-union, infected implant, implant failure or during exchange nailing procedure. Implant removal surgery presents some unique challenges to the Orthopaedic surgeons like broken nails, broken screws and failure of the extraction devices to engage with the threads of the nail due to stripping of the threads in the proximal part of the nail...

BACKGROUND: The Tigertriever stent retriever (Rapid Medical) can be actively expanded and contracted by the operator, which allows for several actuation-related parameters to be optimized to potentially improve device efficacy. These parameters have not yet been evaluated. We conducted a benchtop study to evaluate the effect of actuation frequency on clot integration within the stent. METHODS: A Tigertriever 17 device was deployed within a biological clot analog placed in a straight tube...

BACKGROUND: Tension band wiring and plate fixation are common internal fixation methods used for olecranon fractures, but complications and reoperations are common. The purpose of this study is to investigate the clinical outcomes of displaced olecranon fractures treated with olecranon sled internal fixation. METHODS: The data of 39 patients with olecranon fractures treated with olecranon sled in the Department of Traumatology of Beijing Jishuitan Hospital between May 2018 and April 2020 were retrospectively analyzed...

BACKGROUND: Deep brain stimulation (DBS) has consistently demonstrated high efficacy and safety in patients with Parkinson's disease. Twiddler's syndrome is a rare occurrence of hardware failure in patients undergoing neuromodulation. We report here a case of subclinical cable twisting jeopardizing Twiddler's syndrome in a patient with Parkinson's disease who underwent DBS surgery targeting the globus pallidus internus (GPI). CASE DESCRIPTION: A 70-year-old woman with a 7-year history of Parkinson's disease refractory to medication was referred to our department for treatment of involuntary movements of the left hand and leg...

UNLABELLED: The surgical management of patellar fractures typically yielded satisfactory results; however, in situations involving multifragmented patellar fractures or those affecting the inferior pole, it became imperative to employ alternative osteosynthesis techniques that enhanced stability, enabled early rehabilitation initiation, prevented implant failure, and avoided reduction loss before fracture consolidation. In this context, an unconventional osteosynthesis alternative was presented, utilizing an anatomically designed hook plate originally intended for the fifth metatarsal...

BACKGROUND: A Blauth IIIB hypoplastic thumb is a significant functional and cosmetic problem for the developing hand in children. The gold standard in treatment is amputation and index pollicization. Despite the good functional results, some parents do not consent to the operation, mainly for cosmetic reasons. OBJECTIVES: The aim is to present a detailed description and features of the technique used in our department for stabilization of a hypoplastic thumb type Blauth IIIB with a non-vascularized proximal interphalangeal joint from the toe...

Recent and past studies mainly focus on reducing the dead weight of structure; therefore, they considered lightweight aggregate concrete (LWAC) which reduces the dead weight but also affects the strength parameters. Therefore, the current study aims to use varied steel wire meshes to investigate the effects of LWAC on mechanical properties. Three types of steel wire mesh are used such as hexagonal (chicken), welded square, and expanded metal mesh, in various layers and orientations in LWAC. Numerous mechanical characteristics were examined, including energy absorption (EA), compressive strength (CS), and flexural strength (FS)...

Vertebrates rely on rod photoreceptors for vision in low-light conditions. The specialized downstream circuit for rod signalling, called the primary rod pathway, is well characterized in mammals, but circuitry for rod signalling in non-mammals is largely unknown. Here we demonstrate that the mammalian primary rod pathway is conserved in zebrafish, which diverged from extant mammals ~400 million years ago. Using single-cell RNA sequencing, we identified two bipolar cell types in zebrafish that are related to mammalian rod bipolar cell (RBCs), the only bipolar type that directly carries rod signals from the outer to the inner retina in the primary rod pathway...

BACKGROUND: Though there has been considerable effort to implement machine learning (ML) methods for health care, clinical implementation has lagged. Incorporating explainable machine learning (XML) methods through the development of a decision support tool using a design thinking approach is expected to lead to greater uptake of such tools. OBJECTIVE: This work aimed to explore how constant engagement of clinician end users can address the lack of adoption of ML tools in clinical contexts due to their lack of transparency and address challenges related to presenting explainability in a decision support interface...

Closed-loop sleep modulation is an emerging research paradigm to treat sleep disorders and enhance sleep benefits. However, two major barriers hinder the widespread application of this research paradigm. First, subjects often need to be wire-connected to rack-mount instrumentation for data acquisition, which negatively affects sleep quality. Second, conventional real-time sleep stage classification algorithms give limited performance. In this work, we conquer these two limitations by developing a sleep modulation system that supports closed-loop operations on the device...

In 2021 and 2022, the national and cross-sector project CAPRIV funded by the French Ministry of Agriculture, made it possible to assess the influence of application techniques associated or not with a hedge or an anti-drift net on spray drift and bystander exposure. The acronym CAPRIV stands for " Concilier l'application des PPP et la protection des riverains " (Reconciling the use of PPPs and the protection of residents), within the orchard, viticulture, and field crops sectors. This specific data article focuses on field crops, especially on wheat...

Birth-associated structural issues with the heart are known as congenital heart disorders or defects. They might alter the heart's regular blood flow. A 10-month-old female child presented to a tertiary care hospital with symptoms of recurrent cyanotic spells with episodes of desaturation a few months after birth. ECG findings depicted a normal sinus rhythm with a right axis deviation along the right ventricular forces. Two-dimensional echocardiography showed a tetralogy of Fallot with pulmonary atresia with a patent ductus arteriosus from the undersurface of the arch with confluent small pulmonary arteries...

Radial neck fractures in children are an uncommon phenomenon. The Metaizeau technique for closed intramedullary nailing is a well-documented method for treating this type of fracture. We performed the Metaizeau technique for radial neck fracture fixation on a 10-year-old Indian male patient. The original method described by Metaizeau was followed, with surgical adjustments based on our experience to achieve a satisfactory result. This report provides the surgeon performing the Metaizeau technique with simple tips to assist in fracture reduction and fixation and avoid loss of reduction...

Child abuse is a matter of serious concern that can often result in devastating injuries. Incidence of spinal injuries from child abuse has been reported in <1-3 % of spinal injury cases. In the present study, a case of thoracolumbar translational injury (AO type C) is presented following an incidence of child abuse in a 2-year-old female. After successful management with operative fixation, the child showed a remarkable recovery in her neurological function with ambulatory power.

BACKGROUND: We have attempted to restore the arc of motion by considering trochlear-coronoid articulation as a complete circle during fixation of the coronoid, even for comminuted coronoid fractures with partial loss of articular cartilage (CCFPLAC), using various kinds of locking plates. Herein, we report the radiological and clinical outcomes after fixation of the basal-1 type of CCFPLAC (O'Driscoll classification) using our method. METHODS: Thirty-one patients diagnosed with CCFPLAC were admitted between January 2012 and December 2020...
