“indeterminate significance”

This omission may be due to difficulties with the collection of adequate and appropriate specimens in younger patients, the indeterminate significance of these organisms in the CF population, and a lack of awareness and consistency among providers in obtaining NTM cultures as part of routine CF care [ 7 ].

Altogether we scored the variant as of Indeterminate significance [ 4 ].

33 (9.19%) samples were classified as non-diagnostic (Bethesda I), 149 (41.50%) as benign (Bethesda II), 47 (13.10%) as atypia of indeterminate significance/follicular lesion of indeterminate significance (AUS/FLUS, Bethesda III), 7 (1.95%) as follicular neoplasm/suspicious for follicular neoplasm (FN/SFN, Bethesda IV), 17 (4.74%) as suspicious for malignancy (SUSP, Bethesda V), and 123 (29.53%) as malignant (Bethesda VI).

Regarding the latter, the increasing use of older donors and the more likely presence of gene mutations associated with clonal hematopoiesis of indeterminate significance (CHIP) in older populations is an emerging concern ( Nawas et al. 2021 ).

MCS swabs from the purulent groin sinus showed mixed growth of indeterminate significance.

This scan was negative for PE but did demonstrate a small focus of peripheral non-specific ground glass opacification in the right lower lobe of indeterminate significance.

[ 17 ] conducted a study on patients with thyroid nodules and indeterminate significance on FNA reported that the higher the BMI was, the lower the malignancy rate was except for women aged 45 or older.

Limitations The current study has some notable limitations, first and foremost among which is our small sample size, possibly explaining the indeterminate significance of some findings.

The analysis revealed 4 mutated genes, comprising 1 pathogenic mutation and 3 mutations of indeterminate significance.

Case 9 was unique in presenting, in addition to the L1436P mutation, a c.5211dup (p.Tyr1738LeufsTer27) duplication of the SCN4A gene of indeterminate significance.

Nasal swab culture during FESS grew mixed faecal flora of indeterminate significance.

In a second case suffering from PPHCD [ 3 ], a standardized SPARK Inherited Retinal Dystrophy (IRD) panel was performed testing several mutations of indeterminate significance across multiple genes, including CCD2D2A, CEP78, NR2E3, PCARE, PEX14, and RPGRIP1.

Chest X-ray showed mild bronchial wall thickening in the right lower zone with a few ill-defined small opacites of indeterminate significance.

Realizing the ever-increasing demand for quality healthcare, contemporary AI has been envisioned to make great strides in clinical data management and perception, with the capability to detect indeterminate significance, predict prognostication, and correlate available data into a meaningful clinical endpoint.

2 ). A CT scan of the abdomen and pelvis 2 months prior to hospital admission found the right upper quadrant lesion most likely attributable to scar tissue, of clinically indeterminate significance.

Unlike heart failure with reduced ejection fraction, the diagnosis of HFpEF can be challenging given that in some cases natriuretic peptide levels may be normal and echocardiographic indices may be of indeterminate significance. 1 , 2 In such cases, stress hemodynamic investigation has proven to be the gold‐standard diagnostic approach. 3 , 4 Key characteristics of hemodynamic responses to exercise in patients with HFpEF compared with normal subjects include marked elevations of pulmonary capillary wedge pressure (PCWP), central venous pressure (CVP), and reduced cardiac output (CO) reserve.

Other studies, however, draw attention to specific drawbacks, such as the difficulty in identifying variants of indeterminate significance, with changes in variant interpretation up to 43 % [66] .

After a while it becomes necessary for him to take refuge in the no man’s land of “dysplasia” and other “entities of unknown or indeterminate significance” and, compiling data for “predicting outcome,” he becomes something like a haruspex, this diviner of antiquity whose function was to predict, for the benefit of the Emperor (the clinician), the issue of a battle by reading in the viscerae of a sacrificed animal (the patient) ( Figure 1 ).

The Afirma Gene Expression Classifier assists in decision making regarding surgical recommendations for aspirates with cytology of indeterminate significance or follicular lesions [ 12 , 56 ].

(0 and 1 were collapsed since 1 represents signal hyperintensity on T2-weighted images of indeterminate significance.) Subchondral sclerosis was scored at baseline from 0 to 3 for each region of the knee as: 0: none, 1: <25% of the subregion, 2: 25–50% of the subregion, 3: >50% of the subregion.

Category III (L3), also known as atypia of indeterminate significance, was implemented by the Sydney system to ensure a high accuracy in identifying benign and malignant cases by maintaining high negative and positive predictive values, respectively.

The role of MEG also extends to the identification of a probable contributory lesion in MRIs with multiple lesions, or in lesions of indeterminate significance ( 54 ).

Cytological results of non-diagnostic lesions and lesions of indeterminate significance (atypia of undetermined significance, and suspicions of follicular neoplasm and malignancy) without surgical confirmation were excluded from the study.

The fact that these unrequested findings can be detected without additional radiation exposure is pitted against the indeterminate significance of many unrequested findings and the risk and cost of provoking unnecessary follow-up.

The results of cytology testing reported that 48 (8.5%) women had cervical abnormalities, which included 16 (2.8%) classified as ASCUS (Atypical Squamous Cells of Unknown Significance), 6 (1.1%) classified as ASCH (Atypical Squamous Cells of Indeterminate Significance), 16 (2.8%) classified as LGSIL (Low-Grade Squamous Intraepithelial Lesion), 4 (0.7%) classified as HGSIL (High-grade squamous intraepithelial lesion), and 6 (1.1%) classified CIN II + CIN III (Cervical Intraepithelial Neoplasia) (Table 1 ).
