Postoperative short-term prognostic factors in patients with primary lung cancer who undergo lobectomy: a study on the prognostic predictors of early postoperative recurrence.

Background: Lung cancer is among the most common types of cancers worldwide, and surgery can be a curative treatment option for this condition. However, some patients experience postoperative recurrence. Hence, predicting early postoperative recurrence to improve patient prognosis is important.

Single-Leg Loading Test to Predict Time to Jog and Return to Sports after Acute Lateral Ankle Sprain in Competitive Athletes.

In a previous study, the utility of a single-leg loading (SLL) test after acute lateral ankle sprain (LAS) was reported. However, whether the severity level assessed by the SLL test is associated with the time to jog and return to sports (RTS) remains unclear. Therefore, this study aimed to examine whether the time to jog and RTS differ depending on the severity level.

Effect of resected lung lobe on the prediction of postoperative pulmonary function.

Objectives: This study examined whether a resected lung lobe can affect the accuracy of postoperative forced expiratory volume in 1 s (FEV1) predicted using the subsegment counting method and three-dimensional computed tomography (3D-CT) volumetry.

Methods: Overall, 125 patients who underwent lobectomy through video-assisted thoracic surgery were enrolled in this retrospective study. Pulmonary function tests were performed preoperatively and postoperatively at 3 months.

Drug Treatment for Patients with Postoperative Delirium and Consultation-Liaison Psychiatry in Japan: A Retrospective Observational Study of a Nationwide Hospital Claims Database.

Background: Delirium is the most commonly experienced disorder in consultation liaisons. There are currently research and guidelines in Japan for delirium treatment. Still, there is no retrospective observational study of consultation-liaison psychiatry (CLP) and antipsychotic-centered drugs.

Quick and simple test to evaluate severity of acute lateral ankle sprain.

Background/objective: For early return to sports after a lateral ankle sprain (LAS) and recurrence prevention, effective rehabilitation and gradual return to sports should be initiated while predicting the return time based on the appropriate severity evaluation immediately after injury. However, since severity evaluations performed in previous studies required large space and stairs and involved high-revel activity, their use as a test and index to evaluate severity after LAS was not appropriate considering convenience and risk of re-injury. Therefore, a quick and simple test was developed to evaluate the severity of acute LAS.

Wireless Monitoring Using a Stretchable and Transparent Sensor Sheet Containing Metal Nanowires.

Mechanically and visually imperceptible sensor sheets integrated with lightweight wireless loggers are employed in ultimate flexible hybrid electronics (FHE) to reduce vital stress/nervousness and monitor natural biosignal responses. The key technologies and applications for conceptual sensor system fabrication are reported, as exemplified by the use of a stretchable sensor sheet completely conforming to an individual's body surface to realize a low-noise wireless monitoring system (<1 µV) that can be attached to the human forehead for recording electroencephalograms. The above system can discriminate between Alzheimer's disease and the healthy state, thus offering a rapid in-home brain diagnosis possibility.

Background: Recurrence of pneumothorax after thoracoscopic surgery is a concerning issue for thoracic surgeons. In this study, we aimed to determine the risk factors for recurrence of spontaneous pneumothorax after thoracoscopic surgery.

Methods: A total of 192 patients with spontaneous pneumothorax aged <50 years who underwent thoracoscopic surgery from January 2010 to December 2016 were included in this study.

Highly-ordered Triptycene Modifier Layer Based on Blade Coating for Ultraflexible Organic Transistors.

We present a highly ordered surface modification layer for polymers based on ambient solution-processed triptycene (Trip) derivatives for high-mobility organic thin-film transistors (OTFTs). The nested packing of Trip molecules results in the formation of 2D hexagonal arrays, which stack one-dimensionally on the surface of polymer dielectrics without anchoring groups. The Trip surface was previously shown to be preferable for the growth of organic semiconductors (OSCs), and hence for enhancing the mobility of OTFTs.

Fine printing method of silver nanowire electrodes with alignment and accumulation.

One-dimensional metal nanowires offer great potential in printing transparent electrodes for next-generation optoelectronic devices such as flexible displays and flexible solar cells. Printing fine patterns of metal nanowires with widths <100 μm is critical for their practical use in the devices. However, the fine printing of metal nanowires onto polymer substrates remains a major challenge owing to their unintended alignment.

Long-Term Implantable, Flexible, and Transparent Neural Interface Based on Ag/Au Core-Shell Nanowires.
