Background: Preoperative screening for malnutrition has become mandatory in The Netherlands. A sensitive method to diagnose malnutrition would save time and improve effectiveness.
Methods: A prospective cross-sectional study of 488 adult elective preoperative outpatients was performed. The accuracy of self-reported height and weight was compared with measured data and 3 commonly used malnutrition screening tools. Interobserver agreement was calculated by the intraclass correlation coefficient, studied in Bland and Altman plots, and analyzed by using Cohen's κ statistic. Accuracy was expressed in sensitivity, specificity, and false-negative rates.
Results: Differences between self-reported and measured data were significant, but clinically irrelevant, because only 1 patient was falsely identified as well nourished. Intraclass correlation coefficient for height, weight, and body mass index was high (.97-.99). Bland-Altman plots showed that the mean ± standard deviation differences and 95% limits of agreement between both methods were as follows: height, .0096 m (±.0262, -.0417 to +.0609 m); weight, -1.28 kg (±2.29, -5.76 to +3.20 kg); body mass index, -.72 kg/m(2) (±1.11, -2.92 to +1.46 kg/m(2)). The κ coefficient was .84 (95% confidence interval, .75-.94). Sensitivity was .97 and specificity was .98. Sensitivity and false-negative rates of self-reported data were better overall compared with the screening tools.
Conclusions: Self-reported data provide highly sensitive information to diagnose malnutrition in preoperative outpatients.

Impact of titanium mesh cage slotting width on anterior cervical corpectomy and fusion for compression cervical spondylosis with MRI T2WI hyperintensity: a one-year follow-up study.

Background: Anterior cervical corpectomy and fusion (ACCF) is a standard surgical procedure for cervical spondylosis with spinal cord compression (CSWSCC), especially in patients with intensity on T2-weighted imaging high signal (T2WIHS). The titanium mesh cage (TMC) utilized in this procedure is essential in stabilizing the spine; however, the optimal slotting width of the TMC remains unclear.
Objective: This study aimed to investigate the impact of TMC slotting width on the clinical and radiological outcomes of ACCF in patients with spinal cord compression type cervical spondylosis with intensity on T2WIHS (CST2WIHS).

Background: While the line joining the posterior superior iliac spine (PSIS) intersects a relatively stable sacral vertebra, it does not directly facilitate the localization of lumbar interspace or assist in the positioning for neuraxial anesthesia. Our study aimed to explore the potential of the PSIS line as a reference point and to determine its practical applicability in clinical settings.
Methods: We consecutively enrolled pregnant women with gestational ages ranging from 24 to 38 weeks scheduled for magnetic resonance imaging (MRI) examination.

The core advantage of metalenses over traditional bulky lenses lies in their thin volume and lightweight. Nevertheless, as the application scenarios of metalenses extend to the macro-scale optical imaging field, a contradiction arises between the increasing demand for large-aperture metalenses and the synchronous rise in design and processing costs. In response to the application requirements of metalens with diameter reaching the order of 10λ or even 10λ, this paper proposes a novel design method for fixed-height concentric-ring metalenses, wherein, under the constraints of the processing technology, a subwavelength 2D building unit library is constructed based on different topological structures, and the overall cross-section of the metalens is assembled.

Background/aim: Hallux valgus (HV) is the most common deformity of the forefoot. Although HV has been strongly associated with a family history, its genetic underpinnings remain unclear. Few studies have examined the relationship between folic acid metabolism, which is critical in normal bone development, and HV.

Background/aim: The present study aimed to assess the relationship between the maximum standardized uptake value (SUVmax) on F-fluorodeoxyglucose positron emission tomography computed tomography (F-FDG-PET/CT) and the geriatric nutritional risk index (GNRI) in patients with soft-tissue sarcomas (STSs).
Patients And Methods: The present single-center retrospective observational study included patients who underwent F-FDG-PET/CT and for whom serum albumin levels, height, and body weight were measured prior to therapeutic intervention.
Results: A total of 81 patients were included in the study.
