Following heat illness, a return to activity may require passing a heat tolerance test (HTT). However, there are several logistical limitations to the widespread use of the HTT. Thus, it would be adva...
Sixty-five subjects visited the lab on 3 separate days. The first visit consisted of completing a maximal oxygen uptake (VO2 max) test to assess cardiovascular fitness. For lab visits 2 and 3, subject...
Forty-eight subjects were classified as heat-intolerant and 17 subjects as heat-tolerant. Using the criterion of a HR ≥130 bpm at 30 min of exercise in the thermoneutral environment, specificity (54%)...
Exercise in a thermoneutral environment had a positive predictive value of 100%, thus, if a subject has a HR ≥130 bpm at 30 min of exercise in a thermoneutral environment, they are very likely to fail...
The advancement in CRISPR-Cas biosensors has transmuted the detection of plant viruses owing to their rapid and higher sensitivity. However, false positives and restricted multiplexing capabilities ar...
As a result of falls, older patients experience injury and loss of function, and their length of hospital stay and care costs increase....
This study was conducted to determine fall risks and compare the sensitivity and specificity of three fall risk assessment tools....
Older patients' fall risk levels were determined according to the Itaki, Hendrich-II, and Morse tools within 2 h following their admission to the wards. A methodological design was used in the study, ...
According to the ROC curve values of Sensitivity and 1-Specificity, the cut-off points for the Hendrich-II, Itaki, and Morse fall tools were accepted as 27.5, 8.5, and 6.5, respectively. According to ...
The Itaki Fall Risk Tool was found to be the most sensitive one among the three instruments in assessing the fall risk of older hospitalized patients. The Itaki Fall Risk Tool was followed by the Mors...
Serological tests are widely used in various medical disciplines for diagnostic and monitoring purposes. Unfortunately, the sensitivity and specificity of test systems are often poor, leaving room for...
SIT² involves confirmatory retesting of samples with results falling in a predefined retesting zone of an initial screening test, with adjusted cut-offs to increase sensitivity. We verified and compar...
The specificity of SIT² was superior to single tests and non-inferior to OTA. The sensitivity was maintained or even improved using SIT² when compared with single tests or OTA. SIT² allowed correct id...
For SARS-CoV-2 serology, SIT² proved to be the best diagnostic choice at both 5% and 20% seroprevalence in all tested scenarios. It is an easy to apply algorithm and can potentially be helpful for the...
The digestion of protein into peptide fragments reduces the size and complexity of protein molecules. Peptide fragments can be analyzed with higher sensitivity (often > 10...
Vertical root fracture (VRF) in root-canal-treated teeth frequently results in tooth loss, partly because VRFs are difficult to diagnose and when detected the fracture is often beyond the point of pre...
A total of 120 extracted human tooth roots were root canal treated using common techniques, and VRFs were mechanically induced in a proportion. Samples were imaged using MRI, CBCT, and microCT. Axial ...
Intra-rater reliability was 0.29-0.48 for MRI and 0.30-0.44 for CBCT. Inter-rater reliability for MRI was 0.37 and for CBCT 0.49. Sensitivity was 0.66 (95% confidence interval [CI], 0.53-0.78) and 0.5...
There was no significant difference in sensitivity or specificity between MRI and CBCT in detecting VRF, despite the early-stage development of MRI....
Syphilis is a sexually transmitted disease caused by the spirochaete bacterium Treponema pallidum. This study has developed a multiplex High-Resolution Melt-curve Loop-mediated isothermal amplificatio...
Seasonal influenza leads to an increase in outpatient clinic visits. Timely, accurate, and affordable testing could facilitate improved treatment outcomes. Rapid influenza diagnostic tests (RIDTs) pro...
We performed a post-hoc assessment of surveillance data amassed over seven years from five primary care clinics. We analyzed 4,475 paired RIDT and RT-PCR results from specimens collected from patients...
In an unadjusted analysis, greater sensitivity was associated with the presence of an influenza-like illness (ILI), no other virus detected, no seasonal influenza vaccination, younger age, lower cycle...
Clinical and laboratory factors may affect RIDT sensitivity. Identifying potential factors during point-of-care testing could aid clinicians in appropriately interpreting negative influenza RIDT resul...
The World Health Organization has developed the Integrated Care for Older People (ICOPE) program, a public health strategy to maintain older adults' functional abilities and promote healthier aging. T...
Electronic searches were conducted in the PubMed, Cochrane, Embase, and SciElo databases, the medRxiv platform, and recent human aging scientific events, looking for research analyzing the ICOPE scree...
Currently available data are heterogeneous, and different results were found among the studies due to diverse settings and methodologies. The evidence on the ICOPE screening tool's performance in diff...
Nucleic acid testing based on DNA amplification is gradually entering people's modern life for clinical diagnosis, food safety monitoring and infectious disease prevention. Polymerase chain reaction (...
In this work, we demonstrated that a nanomaterial boron nitride nanoplate (BNNP), due to its unique surface properties, can interact with the main components of the amplification reaction, such as sin...
This is the first systematic demonstration of BNNPs as a promising additive to enhance the efficiency and fidelity of PCR and LAMP amplification reactions, thereby greatly expanding the application of...
