Nailfold comparable provider course and cases — practical program for U.S. clinical research centers · body
Quick answer
Run a compact, research-focused workshop that (1) teaches basic capillary anatomy and standardized imaging SOPs, (2) gives hands-on practice with a digital/video comparable provider, (3) presents a curated case library (normal, Raynaud’s, early/active scleroderma patterns, and common artifacts), and (4) maps scoring tasks to research outputs (image-level metadata, structured scoring forms, and inter-rater reliability rules). The program should produce three deliverables: an imaging SOP for site use, a 25–40 case reference set for rater calibration, and a reproducible scoring template used during study data collection. We use the MAIKONG MKXW880-class device specifications as a practical reference for equipment setup and image QC. (See the Direct answer and Evidence sections for actionable checklists and device parameters.)

Direct answer: a concise program you can run
Design a one-day (intro + hands-on) or two-half-day program that produces three concrete outputs for a clinical study: an imaging SOP, a calibrated case library, and a scoring/data-QC template. Structure the learning around these practical tasks so staff leave able to acquire study-grade images and reproduce a pre-specified scoring protocol.
What to teach (minimum content)
Essential microvascular anatomy and common capillaroscopic patterns used in rheumatology and microvascular research.
Standardized imaging protocol: room setup, patient preparation, finger positioning, use of immersion oil, and repeatability rules.
Device handling and image capture with a digital/video comparable provider (focus, illumination, magnification, framing, file export and metadata capture).
Scoring frameworks and quantitative measures: capillary density, giant capillaries, microhemorrhages, avascular areas and scoring thresholds that your study will use.
Data management and image QC workflow for single- and multi-center projects: labeling, metadata, storage and audit-trail basics.
Collect at least 25–40 validated images or video clips for the training library, including:
Normal controls (age-matched): good illumination, clear loop morphology.
Raynaud’s phenomenon pattern examples (non-scleroderma Raynaud’s where available).
Scleroderma spectrum: early, active and late capillary patterns.
Artifact examples: pressure-induced distortion, movement blur, and skin-surface reflections.
Borderline or ambiguous cases to teach consensus rules.
How to use results in research
Require each image to carry a minimal metadata set (site, operator ID, finger/position, magnification, time stamp) and scoring entries in the study CRF. Use your training library to produce a pre-study calibration exercise: have each rater score a shared 20-case subset, calculate inter-rater agreement, and document remedial training until pre-set reproducibility thresholds are met.
Who this course serves and what clinical research centers must achieve
We designed this program for clinical research centers in the U.S. planning observational or interventional studies that include nailfold comparable provider as an imaging endpoint. Typical learners are site investigators, study coordinators, sonographers/technicians, and core-lab raters. Your operational targets should be pragmatic: consistent image acquisition across sites, reproducible scoring by trained raters, and an audit-ready image and metadata archive suitable for blinded review.

Theory
Cover capillary structure, pathologic patterns relevant to the study population, and how quantitative features are defined. Keep theory focused on features that will appear in the scoring template to avoid irrelevant detail.
Imaging protocol (SOP)
Deliver a written SOP with these required elements: room conditions, patient preparation, finger selection and position, immersion medium, focus and magnification settings, and repeatability checks. Below we give a practical imaging checklist you can adopt directly.
Case selection and scoring frameworks
Teach visual criteria and structured scoring (binary presence/absence plus graded severity where needed). Use the case library for annotation exercises with reference images and consensus annotations.
Data quality and workflow
Define file naming, minimal metadata, local backup, transfer to central repository, and a simple audit-trail of who scored what and when.

Practical checklist we recommend you adopt:
Room temperature and humidity: maintain stable conditions during a session (document the ambient temperature for each session; supplied materials recommend around 22–24°C but centers should set their own controlled range and record it).
Patient rest: have participants rest 15 minutes before imaging and keep the hand at heart level.
Use two drops of an immersion oil (e.g., cedar or paraffin) to reduce surface reflection.
Finger positioning: secure rest/holder to avoid lateral movement; align the first capillary row in the field of view before capture.
Timing and repeatability: capture at least two frames per finger and repeat imaging of a subset (5–10%) to assess intra-operator variability.
Device hands-on: using a digital/video comparable provider system (MKXW880-class checklist)
Nailfold comparable provider course and cases — practical program for U.S. clinical research centers · body
We use MAIKONG device parameters as a practical reference for imaging setup. The MKXW880-class systems provide a cold LED light source, manual focus, and magnification useful for most capillaroscopic research settings; confirm final configuration for your protocol.
12V (AC input 100–240V 50/60Hz; DC output DC12V, 2A)
Magnification (times)
680 / 1200
Working distance
25 mm
Focus type
manual focus
Weight (unit)
5.2 kgs (gross weight 8 kg)
Practical device checklist for trainees:
Power and illumination: verify stable cold-LED illumination and consistent brightness for each capture.
Magnification and framing: choose magnification to include a 1–2 mm capillary field that shows the first capillary row; record the magnification setting per-image in metadata.
Focus: use coarse then fine manual focus; document the working distance and confirm no contact-induced compression.
File formats and export: capture lossless or high-quality compressed images or short video clips and ensure automatic time-stamping and operator ID fields are attached.
Operator ergonomics: set a finger rest and stabilizer; train on avoiding pressure and controlling lateral shifts.
Case library: minimum case mix and examples to include
Nailfold comparable provider course and cases — practical program for U.S. clinical research centers · body
Create a curated repository of 25–40 labeled examples for training and calibration. At minimum include:
8–12 normal controls across age ranges (clear frames, correct focus).
6–8 Raynaud’s pattern examples, with notes on clinical context.
6–8 scleroderma-spectrum examples showing early, active and late patterns.
Scoring and quantitative approaches for research: what to collect and how to document reproducibly
Nailfold comparable provider course and cases — practical program for U.S. clinical research centers · body
Keep data collection narrow and reproducible. Required image-level fields we recommend:
Site ID, operator ID, subject ID (study assigned), finger and side, magnification, illumination level, and image timestamp.
Structured scoring elements (example): capillary density (loops/mm), giant capillaries present (Y/N), microhemorrhages count, avascular areas (mm), and a global pattern label.
Audit fields: scorer ID, scoring timestamp, and a free-text field for comments.
Store scores as structured data (CSV/JSON) linked to file names, not embedded only in image filenames.
Data management and image QC for multicenter studies: labeling, metadata, storage and basic audit trail

Best-practice checklist:
Enforce a naming convention: SITE_SUBJECT_FINGER_DATE_TIME_OPERATOR.ext
Automate metadata capture where possible; require manual entry fields to be completed before export.
Use a central repository with versioning and restricted write access; maintain a read-only archive of raw captures.
QC workflow: a sample-based QC (10% of images) for illumination, focus, framing and artifact rate, with corrective feedback to sites.
Training assessment: competency checklist, sample practical exam and inter-rater reliability exercise
Competency checklist (pass/fail items): correct finger placement and oil use, stable focus and framing, export with required metadata, and correct initial scoring on five calibration cases. For assessment, run a blinded practical exam: each trainee acquires images from two volunteers and scores a common 10-case set. Use the results to compute inter-rater agreement; repeat targeted training if agreement falls short of your pre-defined threshold.
Regulatory, ethics and workflow considerations for U.S. research centers
U.S. sites must treat nailfold comparable provider as an imaging procedure embedded in a protocol. Key steps:
Include imaging procedures in the IRB submission with a clear description of risks, data handling, and storage.
Obtain informed consent that covers image capture, storage, possible sharing with a central reader and de-identification procedures.
Device labeling and use: confirm that the device labeling and intended use align with your study activities — supplied manufacturer materials list CE and ISO declarations but the supplied evidence does not document U.S. regulatory clearance; verify local regulatory status and labeling before clinical use.
Site electrical/install requirements: we do not have specific U.S. electrical or installation approval details in the supplied materials; confirm power compatibility, grounding and installation with the device manual and local institutional engineering teams before deployment.
