This retrospective case series enrolled 13 patients who underwent posterior fixation with both transdiscal screws for diffuse idiopathic skeletal hyperostosis (TSDs) and pedicle screws (PSs) to treat spinal injury accompanied by diffuse idiopathic skeletal hyperostosis (DISH). To describe the usefulness, feasibility, and biomechanics of TSD. Vertebral bodies accompanied by DISH generally have lower bone mineral density than normal vertebral bodies because of the stress shielding effect. This phenomenon tends to makes screw fixation challenging. To our knowledge, solutions for this issue have not previously been reported. Patients were assessed using the data on surgical time, estimated intraoperative blood loss, mean number of stabilized intervertebral segments, number of screws used, perioperative complications, union rate, and the three-level EuroQol five-dimensional questionnaire (EQ5D-3L) score at the final follow-up. The Hounsfield unit (HU) values of the screw trajectory area, and the actual intraoperative screw insertion torque of TSDs and PSs were also analyzed and compared. The surgical time and estimated intraoperative blood loss were 165.9±45.5 minutes and 71.0±53.4 mL, respectively. The mean number of stabilized intervertebral segments was 4.6±1.0. The number of screws used was 4.9±1.3 for TSDs and 3.0±1.4 for PSs. One death occurred after surgery. The union rate and EQ5D-3L scores were 100% and 0.608±0.128, respectively. The HU value and actual intraoperative screw insertion torque of TSDs were significantly better than those of PSs ( We were able to achieve stable surgical outcomes using the combination of TSDs and PSs. The HU value and actual intraoperative screw insertion torque were significantly higher for TSDs than for PSs. Based on these results, when treating thoracolumbar spinal fractures accompanied by DISH in elderly populations, the TSD could be a stronger anchor than the PS.

This paper reports the clinical findings and surgical treatment of feline right patent ductus arteriosus (RPDA) with a left aortic arch. A two-month-old female Maine Coon was referred for an investigation of regurgitation after weaning. RPDA with a left aortic arch was diagnosed based on the echocardiographic and computed tomography (CT) findings.A right-fourth intercostal thoracotomy was found to be an appropriate approach to the duct. Preoperative diagnosis is crucial and diagnostic imaging, including radiography, echocardiography, and cardiac CT examination, is essential for determining if the aortic arch is right or left.

Background:
Calf muscle circumference is a potential alternative for measuring skeletal muscle mass. However, the association between calf muscle circumference and sarcopenia and the reliability of sarcopenia diagnosis based on calf muscle circumference have not been well reported. In this study, we aimed to determine the usefulness of calf muscle circumference measurement in the diagnosis of sarcopenia.
Methods:
A cross-sectional study was conducted using data collected from 63 older adults (40 male and 23 female; mean age, 79.7±6.5 years) using day-care rehabilitation. Sarcopenia was defined according to the guidelines of the 2019 Asian Working Group for Sarcopenia (AWGS 2019). The association between sarcopenia and calf muscle circumference was determined using multiple regression analysis, and the reliability of sarcopenia diagnosis based on calf muscle circumference was determined using the kappa coefficient.
Results:
Overall, 36.5% (30.4% female and 40.0% male) of the participants had sarcopenia. Calf muscle circumference was independently associated with sarcopenia. The best cutoff points for calf muscle circumference to identify older adults at risk of low skeletal muscle mass were 28.7 cm and 31.1 cm for female and male participants, respectively. Furthermore, the kappa coefficient between sarcopenia diagnosed using calf muscle circumference and that diagnosed using the AWGS 2019 criteria was 0.80.
Conclusions
Calf muscle circumference is independently and significantly associated with sarcopenia in older adults requiring long-term care. Calf muscle circumference is a surrogate for skeletal muscle mass and thus may be used to diagnose sarcopenia.
