Food and Drug Administration-approved TRK inhibitors with impressive overall response rates are now available for patients with multiple cancer types that harbor NTRK rearrangements, yet the identification of NTRK fusions remains a difficult challenge. These alterations are highly recurrent in extremely rare malignancies or can be detected in exceedingly small subsets of common tumor types. A 2-step approach has been proposed, involving a screening by immunohistochemistry (IHC) followed by a confirmatory method (fluorescence in situ hybridization, reverse transcriptase-polymerase chain reaction, or next-generation sequencing) in cases expressing the protein. However, there is no interpretation guide for any of the available IHC clones.
To provide a pragmatic update on the use of pan-TRK IHC. Selected examples of the different IHC staining patterns across multiple histologies are shown.
Primary literature review with PubMed, combined with personal diagnostic and research experience.
In-depth knowledge of pan-TRK IHC will help pathologists implement a rational approach to the detection of NTRK fusions in human malignancies.

The increased emphasis on implementing evidence-based practice has reinforced the need to more accurately assess patient improvement. Psychometrically sound, patient-reported outcome measures are essential for evaluating patient care. A patient-reported outcome instrument that may be useful for clinicians is the Disablement in the Physically Active Scale (DPAS). Before adopting this scale, however, researchers must evaluate its psychometric properties, particularly across subpopulations.
To evaluate the psychometric properties of the DPAS in a large sample using confirmatory factor analysis procedures and assess structural invariance of the scale across sex, age, injury status, and athletic status groups.
Observational study.
Twenty-two clinical sites.
Of 1445 physically active individuals recruited from multiple athletic training clinical sites, data from 1276 were included in the analysis. Respondents were either healthy or experiencing an acute, subacute, or persistent musculoskeletal injury.
Ameasure for assessing disablement and quality of life. Use of the 16-item DPAS across subpopulations of interest is not recommended. More examination involving a true cross-validation sample should be completed on the 8-item DPAS before this scale is adopted in research and practice.
Recently, an exchangeable copper (CuEXC) assay has been suggested as a robust and feasible diagnostic tool for Wilson disease (WD). Although WD is a disorder that requires lifelong treatment and monitoring, few data are currently available regarding the status of copper levels in children.
To evaluate the performance of copper assays and establish a reference interval for total copper and CuEXC in the pediatric population.
Serum samples from children aged 1-5 (n = 122), 6-12 (n = 125), and 13-18 years (n = 120) were analyzed. AZ191 molecular weight Total copper and CuEXC concentrations were directly measured using inductively coupled plasma mass spectrometry, and relative CuEXC levels were calculated. Total copper reference intervals, CuEXC levels, and relative CuEXC levels were determined based on the 2.5th and 97.5th percentiles of the data with 90% confidence intervals.
There were significant differences in the median concentrations of total copper and relative CuEXC among the age groups. Reference intervals determined for total copper were 82 to 167, 75 to 139, and 64 to 133 μg/dL for children aged 1 to 5, 6 to 12, and 13 to 18 years, respectively. The reference intervals for CuEXC were 4.29 to 9.79, 4.02 to 9.09, and 3.55 to 8.25 μg/dL for children aged 1 to 5, 6 to 12, and 13 to 18 years, respectively. Among 11 patients with suspected WD, relative CuEXC values were elevated in all 3 diagnosed with WD.
The pediatric reference intervals derived in this study are expected to be useful for the diagnosis, differential diagnosis, treatment, and monitoring of pediatric patients with WD.

The first Covid-19 lockdown in India was announced on March 24, 2020, with less than four hours' notice, leaving older adults without access to domestic help and paid caregivers. As traditional caregiving models ceased to function in the new setup, relatives of older adults turned to strangers and volunteers in an effort to provide urgent care to their older family members.
A pan-India group of volunteers was formed during the lockdown on a popular social media website to connect people of all ages in need of help with those able to offer assistance. A sample of 242 messages pertaining to older adults was extracted for quantitative content analysis.
All but two requests were placed by adult relatives of older adults. Requests covered a number of needs, some of which were directly tied to the pandemic and lockdown, while others were general in nature but were greatly exacerbated by recent events.
The use of social media to encourage acts of kindness at a time of crisis was an innovative attempt to meet the immediate needs of older adults. The lockdown, however, exposed the lack of dedicated supports and services for older adults in India.

The global impact of the new 2018 American Society of Clinical Oncology/College of American Pathologists human epidermal growth factor receptor 2 (HER2) practice guideline update on the overall HER2 status designation, compared with the prior 2013 iteration, is unknown.
To report the quantitative impact of the new guideline on HER2 status distribution.
The analysis comprised a retrospective cohort of patients from the author's institution, combined with other peer-reviewed publications that assessed the impact of the 2018 guideline in relation to the 2013 guideline.
Our study revealed that the new guideline led to an average 9% reclassification rate for the overall HER2 status, with a net gain in overall HER2 negative designation. This is largely due to reclassification of the equivocal (Group 4) groups. Unexpectedly, infrequent but consistent discordance between Group 1/5 and fluorescence in situ hybridization results are observed across studies (1.8%; 73 of 3965 cases where fluorescence in situ hybridization and immunohistochemistry are both reported).
