CQ-001 · bone · research priority: high · don’t-miss review priority

Would paired bone formation markers (P1NP, bone-specific ALP ± osteocalcin), interpreted with preanalytical standards, help classify turnover before any long-term bone-agent class discussion?

Rationale. Formation markers are not documented in the public ledger; CTX alone (upper-normal, fasting unknown) cannot establish formation–resorption uncoupling. BTM use for monitoring/interpretation and sex-specific reference intervals are the relevant literature (not densitometry-only guidance).

lit-0012: Markers of bone turnover for the prediction of fracture risk and monitoring of osteoporosis treatment: a need for international reference standards (2011)Why cited / applicability: IOF-IFCC position paper establishing s-CTX and s-PINP as reference BTMs for research and clinical monitoring standards.
lit-0297: Reference Intervals for Serum Concentrations of Three Bone Turnover Markers for Men and Women (2013)Why cited / applicability: SHIP population reference intervals for PINP, BAP, and CTX including 1107 men plus pre-/postmenopausal women—critical for interpreting CTX in men rather than only postmenopausal ranges.

CQ-002 · bone · research priority: high · don’t-miss review priority

On the next same-scanner DXA, can age-appropriate Z-scores be reported and can hip BMD change be interpreted against a facility-derived LSC? If vertebral fracture assessment (VFA) is considered, does the patient meet formal indication criteria rather than low BMD alone? Trabecular bone score (TBS), if discussed, is per ISCD generally for ages ≥40 with male fracture-risk evidence primarily studied above age 50 — this patient is ~38, so is TBS applicable now, or better deferred?

Rationale. ISCD 2023 Adult Official Positions (lit-0015 / Shuhart et al. J Clin Densitom 2023 doi 10.1016/j.jocd.2023.101435): Z-scores preferred in men <50; osteoporosis cannot be diagnosed on BMD alone under 50; each facility should determine precision error and calculate LSC (manufacturer LSC not a substitute) for serial change; TBS is appropriate in adults ≥40 (male fracture-risk evidence primarily studied above age 50) and routine TBS-change monitoring is not recommended; VFA has formal indication criteria not met by young age + low BMD alone without other triggers. Age ~38 at latest scans — all four points are carried on the lit-0015 card quality_notes/body.

lit-0015: Executive Summary of the 2023 Adult Position Development Conference of the International Society for Clinical Densitometry: DXA Reporting, Follow-up BMD Testing and Trabecular Bone Score Application and Reporting (2023)Why cited / applicability: Peer-reviewed executive summary of the 2023 ISCD Adult Position Development Conference (Shuhart et al., J Clin Densitom; doi 10.1016/j.jocd.2023.101435). Society positions page also at iscd.org/official-positions-2023/. Core densitometry rules used here: Z-scores preferred in males <50; osteoporosis not diagnosed by BMD alone under age 50; each DXA facility should determine its precision error and calculate the LSC (manufacturer LSC not a substitute); TBS is appropriate in adults aged ≥40 years (male fracture-risk evidence primarily studied above age 50); VFA has formal indication criteria — low BMD/young age alone is not a VFA indication without other triggers.

CQ-003 · renal_bone · research priority: high

Is controlled calcium-flux phenotyping (sodium-aware 24h urine with stone profile + fasting urine Ca/Cr + paired serum Ca/PTH/PO4) appropriate to classify hypercalciuria mechanism?

Rationale. Serial 24h urine calcium values 283→254→333 mg/24h in a male (common male threshold often 300 mg/day or 4 mg/kg; 2 of 3 collections below 300; middle value 254 normal at performing lab ref 100–300 vs Litholink 40–250). Mechanism (absorptive vs renal leak vs resorptive) incomplete; high urine Na noted. Counter-consideration from AUA 2014 Statement 7 (Recommendation, Grade C) — clinicians should NOT routinely perform "fast and calcium load" testing to distinguish among types of hypercalciuria, because it has not been shown to change clinical practice — and that guideline population is stone formers, whereas this record documents one lifetime stone, passed spontaneously, and no stones on the CT urogram of 2026-02-27. That is a stone-forming history at its mildest end rather than an absence of one, so the guideline population overlaps this record weakly rather than not at all (COR-0042). Sodium-aware 24-h panel framing (AUA Statement 6) is the better-supported element; mechanism-classification testing remains a research question, not a mandated order.

Literature.

lit-0013: Idiopathic hypercalciuria: Can we prevent stones and protect bones? (2018)Why cited / applicability: Practical CCJM review; notes idiopathic hypercalciuria in 10–19% of men with low bone mass and direct trabecular bone loss especially in men.
lit-0152: Urine calcium excretion predicts bone loss in idiopathic hypercalciuria (2006)Why cited / applicability: Longitudinal BMD data in IH stone formers; links magnitude of calciuria to femoral-neck rate of loss. Cited IH literature describes mild BMD reduction / rate-of-loss association; does not account for spine T −4.3 magnitude. The record documents one lifetime stone, passed spontaneously, and no stones on CT urogram 2026-02-27, so this cohort applies weakly rather than not at all (COR-0042).
lit-0226: Medical Management of Kidney Stones: AUA Guideline (2014)Why cited / applicability: AUA medical management guideline for adult kidney stone formers. Free full text. Statement 6 supports sodium-aware 24-h urine panels in the stone-former population. Extrapolation to this record — a minimal-burden stone-former with low BMD, one lifetime stone passed spontaneously — is the project's own inference, not a guideline claim. Not "directly portable." Statement 7: do NOT routinely perform fast-and-calcium-load testing.

CQ-004 · genetics · research priority: high · don’t-miss review priority

Is an early-onset osteoporosis / bone-fragility gene panel appropriate, with counseling that related-cohort pathogenic yields are modest and that variants of uncertain significance may complicate interpretation?

Rationale. Best single-primary research alternative remains genetically untested; yield honesty required (not high-yield marketing).

lit-0294: Primary Osteoporosis in Young Adults: Genetic Basis and Identification of Novel Variants in Causal Genes (2018)Why cited / applicability: Cohort of 123 young/middle-aged adults with idiopathic OP (Z-score < −2.0, diagnosis before age 55, fracture optional). Secondary causes including hypogonadism were EXCLUSIONS. Yield figures must state numerator/denominator/variant class. Identifiers verified Crossref+NCBI 2026-08.
lit-0293: Mutational Analysis Uncovers Monogenic Bone Disorders in Women with Pregnancy-Associated Osteoporosis: Three Novel Mutations in LRP5, COL1A1, and COL1A2 (2018)Why cited / applicability: n=7 consecutive women with pregnancy-associated osteoporosis; mutational analysis uncovered three novel mutations (LRP5, COL1A1, COL1A2) — 3/7 genetic yield in this small series, not a population rate. Women-only; male applicability is analogy only (physiologic stressors may unmask monogenic fragility). Does not explain spine T −4.3 magnitude by itself.
lit-0287: WNT1 Mutations in Early-Onset Osteoporosis and Osteogenesis Imperfecta (2013)Why cited / applicability: Landmark NEJM report establishing WNT1 as a human bone-mass gene: heterozygous missense → early-onset osteoporosis; biallelic nonsense → recessive OI. Free PMC full text.
lit-0290: PLS3 Mutations in X-Linked Osteoporosis with Fractures (2013)Why cited / applicability: NEJM discovery of PLS3 (plastin-3) X-linked osteoporosis; five families with pathogenic variants; rare PLS3 variant also associated with fracture risk in elderly heterozygous women.

CQ-005 · mast_cell · research priority: high · don’t-miss review priority

Can high-sensitivity peripheral-blood KIT D816V testing be performed with specimen, method, and limit of detection documented?

Rationale. Prior KIT-negative report lacks method/LOD; consensus mast-cell diagnostic pathways require sensitive KIT D816V methods. Negative results without documented assay quality do not fully exclude low-burden disease. (HαT explains basal tryptase separately and is not a substitute citation for KIT methodology.)

CQ-006 · immunology · research priority: high · don’t-miss review priority

Is same-lab, same-assay pre/post pneumococcal polysaccharide vaccine challenge (± Hib as directed) appropriate to adjudicate specific antibody deficiency, given baseline non-protective titers and IgG1-low pattern?

Rationale. Baseline titers are not a vaccine-challenge study; formal SAD criteria require response assessment and infection history.

CQ-007 · metabolic · research priority: medium · don’t-miss review priority

Should serum copper, ceruloplasmin, and zinc be measured as a don’t-miss screen for copper-deficiency myeloneuropathy (which can lack cytopenias)?

Rationale. Copper not documented in public pack; copper-deficiency myeloneuropathy can present with neurologic findings and may lack frank cytopenias. Zinc excess is a risk context. Wilson disease (copper overload) is a different problem and is not the citation basis here.

claims: CLM-0059 · hypotheses: H-NULL

CQ-008 · neurology · research priority: medium

Is an objective small-fiber/autonomic battery (e.g., exam + IENFD ± QST/QSART ± tilt as clinician-directed) appropriate given residual pain with normal large-fiber EMG, without treating symptoms alone as SFN diagnosis?

Rationale. Modern SFN criteria require objective testing; symptoms alone are insufficient.

claims: CLM-0060 · hypotheses: H-NULL

Literature.

lit-0270: Diagnostic criteria for small fibre neuropathy in clinical practice and research (2019)Why cited / applicability: 2019 reappraisal + prospective validation of SFN criteria; OA on PMC. Best modern anchor for clinical + IENFD/QST rules.

CQ-009 · infectious_disease · research priority: medium · don’t-miss review priority

If infection is re-adjudicated, are reference Babesia thin smear + PCR during symptoms and Bartonella culture/PCR/IFA (or tissue only if a safe target exists) the appropriate instruments — rather than IgM churn or post-antibiotic FISH as primary adjudicators?

Rationale. IDSA babesiosis: smear or PCR for confirmation. Specialty FISH/IgM remain contested LDTs; commercial PCR/IB negative on pack.

claims: CLM-0036, CLM-0037 · hypotheses: H4

Literature.

lit-0057: Clinical Practice Guidelines by the Infectious Diseases Society of America (IDSA): 2020 Guideline on Diagnosis and Management of Babesiosis (2021)Why cited / applicability: Primary IDSA evidence-based guideline. Prefers smear/PCR over antibody for acute confirmation. Frames prolonged/relapsing disease mainly in immunocompromised hosts. Guideline is silent on FISH LDTs; smear/PCR standard is the published position — not treating FISH as endorsed. Published corrigendum (Clin Infect Dis 2021 doi 10.1093/cid/ciab275, PMID 33960362) — check publisher record.
lit-0042: Pitfalls and fallacies of cat scratch disease serology: evaluation of Bartonella henselae-based indirect fluorescence assay and enzyme-linked immunoassay (1997)Why cited / applicability: Classic methods paper comparing IFA/ELISA IgM/IgG performance against well-characterized CSD cases and controls. Foundational for skepticism toward isolated serology.
lit-0047: Limitations of Serological Diagnosis of Typical Cat Scratch Disease and Recommendations for the Diagnostic Procedure (2023)Why cited / applicability: Narrative review of 63 papers after screening 437; quantifies poor and heterogeneous serology performance and argues molecular testing of nodes as gold standard for typical CSD.

CQ-010 · endocrine · research priority: medium

Can original hypogonadism-era HPG laboratory reports (around historical T≈34) be reconstructed, and is karyotype/CMA appropriate when clinically indicated?

Rationale. Historical T≈34 is reported_history with incomplete instrument provenance; Endocrine Society hypogonadism guidance informs HPG-axis reconstruction. Karyotype/CMA is a separate cytogenetic indication question (e.g., Klinefelter workup pathways), not established by testosterone-therapy guidelines alone.
