Every case, pathway, and question is mapped to the JAMA 2024 nutrition-competency framework that the USMLE cites as its alignment standard. ## The Four-Pillar Loop Every session follows the same flow: - **Question**: NBME-format vignettes with five lettered choices. Per-distractor mechanism-deep rationales, takeaway summaries, and JAMA competency tags. - **Case**: Open a patient vignette, review the history, order relevant labs at a cost (targeted workups earn more), commit to a differential diagnosis. - **Pathway**: Map the biochemistry. Drag substrate, enzyme, cofactor, and product into a mechanism chain that explains the clinical picture. - **Spaced Repetition**: Missed pathways return tomorrow. Nailed ones advance to 3, 7, or 21 days. Wrong answers become entry points to linked pathways and cases — not dead ends. ## What It Offers - 260+ NBME-format USMLE-style questions across Step 1, Step 2 CK, and Step 3 with per-distractor rationales and clinical takeaways - 100+ clinical cases covering deficiency, toxicity, and dysregulation - 70+ mechanism-chain pathways, each with a clinical pearl - 22 topic anchors: 13 vitamins, 6 minerals, and 3 macronutrient pathways (carbohydrate, fatty-acid, and amino-acid metabolism including urea-cycle nitrogen disposal) - Drug-induced deficiencies taught as causal chains (metformin/B12, phenytoin/folate, TMP-SMX/folate on PCP prophylaxis) plus a searchable drug-nutrient interaction index - Step 2 macronutrient emphasis: gluconeogenesis, insulin signaling, β-oxidation, ketogenesis, NAFLD/SREBP, urea-cycle hyperammonemia - Lifespan-specific pathways: periconception folate, maternal iodine, infant B12, neonatal vitamin K, congenital cretinism - Food allergy vs intolerance discrimination (CMPA, celiac) - Eating-disorder identification with DSM-5 criteria and refeeding-syndrome management protocol - Nutrition label interpretation for chronic-disease counseling - Competency dashboard tracking progress against every JAMA 2024 nutrition competency ## Who It's For - Medical students preparing for USMLE Step 1, Step 2 CK, and Step 3 - M1 / M2 students in biochemistry and nutrition courses - International medical graduates (IMGs) preparing for US licensure - Residents reviewing nutrition for in-training exams or board recertification - PA, NP, and pharmacy students mastering nutrition mechanisms ## Pricing - Free tier: Vitamin B12 unlocked forever — 6 cases (pernicious anaemia, nitrous-oxide SACD, infant of vegan mother, metformin in diabetics, post-bariatric SACD, terminal ileal Crohn), 4 pathways (MMA cycle, breastmilk-infant myelination, metformin–B12, PPI multi-nutrient malabsorption), 17 questions - Full unlock: one-time purchase — all 22 topic anchors, 260+ questions, 100+ cases, 70+ pathways, competency dashboard, every future content update - No subscriptions, no ads, works offline ## Download - iOS: https://apps.apple.com/us/app/kinetics-usmle-nutrition-prep/id6763088313 - Android: https://play.google.com/store/apps/details?id=com.diagnosticstudios.kinetics --- # PathoPlay: Pathophysiology Game > Learn pathophysiology by building disease mechanism chains. Then block them with the right drug. ## What It Offers - 550 mechanism chains across 10 body systems: Cardiovascular, Respiratory, Renal, GI & Hepatology, Neurology, Endocrine, Infectious Disease, Hematology, Reproductive, Rheumatology - Every chain cites Harrison's, Robbins, Goodman & Gilman's, Guyton & Hall, and current guidelines ## Game Modes - Forward Mode (FREE — 200 chains): Build the disease mechanism chain from trigger to clinical outcome - Reverse Mode (Premium): Start with a clinical finding, trace backward to the root cause - Versus Mode (Premium): Two similar diseases side by side — spot the difference (e.g., Crohn's vs UC, ITP vs TTP) - Treat Mode (Premium): A disease pathway is active — pick the right drug, drop it on the right molecular target ## Who It's For - Medical students (preclinical pathophysiology & pharmacology) - Nursing students (NCLEX pathophysiology foundations) - PA / NP students - Pharmacy students (pharmacology by mechanism) - Board prep: USMLE Step 1, NCLEX, HESI ## Pricing - Free: 200 Forward chains across all 10 body systems - All Access: One-time purchase, unlocks all modes and future content - No subscriptions, no ads, works offline ## Download - iOS: https://apps.apple.com/us/app/pathoplay-pathophysiology-game/id6761776544 - Android: https://play.google.com/store/apps/details?id=com.pathoplay.app --- ## How They Work Together PathoPlay builds mechanism foundations — understand WHY diseases happen and WHERE drugs intervene. MedDiagnosis trains clinical reasoning — investigate patients, order tests, diagnose, and treat. Kinetics masters USMLE nutrition biochemistry through the same case-to-mechanism loop. ## How It Differs From Other Tools - vs Anki: Active construction and clinical simulation vs passive flashcard recall - vs Amboss/UWorld: Full patient simulation and mechanism building vs multiple-choice questions - vs Pathoma: Interactive chain-building vs video lectures ## Links - Website: https://diagnosticstudios.com - MedDiagnosis: https://diagnosticstudios.com/meddiagnosis - Kinetics: https://diagnosticstudios.com/kinetics - PathoPlay: https://diagnosticstudios.com/pathoplay - Blog: https://diagnosticstudios.com/blog - Contact: contact@diagnosticstudios.com
