Department of Biochemistry and Molecular Biology, Medical University of Lublin, 20-093, Lublin, Poland.
Using Fourier Transform Infrared spectroscopy (FTIR), it is possible to show chemical composition of materials and / or profile chemical changes occurring in tissues, cells, and body fluids during onset and progression of diseases. For diagnostic application, the use of blood would be the most appropriate in biospectroscopy studies since, (i) it is easily accessible and, (ii) enables frequent analyses of biochemical changes occurring in pathological states. At present, different studies have investigated potential of serum, plasma and sputum being alternative biofluids for lung cancer detection using FTIR.

Research has shown child sexual abuse (CSA) within youth-serving organizations (YSOs) often went undetected for decades, which may in part be due to the use of sexual grooming behaviors. One such YSO is the Boy Scouts of America (BSA), with nearly 100,000 individuals alleging CSA within this organization. This study aimed to describe the characteristics of CSA within the BSA and the presence of sexual grooming behaviors as described by the Sexual Grooming Model.

Key Laboratory for Water Quality and Conservation of the Pearl River Delta, Ministry of Education, School of Environmental Science and Engineering, Guangzhou University, Guangzhou, 510006, China.
Quantifying lacustrine groundwater discharge (LGD) is important for understanding the dynamics of lake ecosystems and their expansion. This study focuses on Lake Qinghai, employing radium isotope models to evaluate the contributions of both shallow and deep groundwater. The data indicate that the activity of Ra and Ra demonstrates a pronounced gradient, decreasing from the shoreline to the center of Lake Qinghai.

Department of Public Health and Primary Care, KU Leuven, Leuven, Belgium.
Background: Frailty screening instruments are increasingly studied as risk predictors for adverse postoperative outcomes. However, because of the lack of comparative research, it is unclear which screening instrument performs best. This study therefore compared the diagnostic accuracy of seven frailty screening instruments for adverse postoperative outcomes in patients aged ≥70 years undergoing colorectal surgery.

Division of Infectious Diseases, Department of Medicine, Duke University School of Medicine, Durham, North Carolina, USA.
Background: Early posttransplant cytomegalovirus (CMV) infections in CMV seronegative solid organ transplant recipients (SOTR) with CMV seronegative donors (D-/R-) are often attributed transfusion-transmitted CMV. The prevalence of false-negative donor CMV serology in D-/R- SOTR with early CMV infections has not been explored.
Methods: We determined the frequency and characteristics of CMV DNAemia that occurred within 90 days of transplant among adult SOTR classified as D-/R- who underwent a first SOT at a single center between February 25, 2014 and February 25, 2024.
