INTERNAL MEDICINE 2026 VOLUME 1: Pathophysiology to Bedside Practice with Current Clinical Guidelines for USMLE and ABIM Board Preparation

You finished a thirty-hour call. You have board certification to prepare for and a stack of clinical questions that no review book has answered at the depth your patients require. The resources written for your stage of training often cite trials that predate the guidelines your attendings now follow. That gap is not abstract. It shows up in rounds, in prescribing decisions, and in examination rooms.Internal Medicine 2026: Pathophysiology to Bedside Practice, Volume 1 was built for the clinician in that gap. Written for PGY-1 through PGY-3 residents, ABIM certification candidates, and MS3 through MS4 students preparing for Step 2 CK and Step 3, this volume covers thirteen chapters across six clinical domains: foundations of clinical reasoning and evidence-based medicine, cardiovascular medicine, pulmonary disease, gastroenterology and hepatology, nephrology and electrolyte disorders, and endocrinology.Every clinical recommendation is anchored to current evidence. The EMPEROR-Preserved and DELIVER trials establish SGLT2 inhibitors for heart failure with preserved ejection fraction. The CREDENCE and DAPA-CKD trials define the cardiorenal protection standard in diabetic kidney disease. The GOLD 2023 ABE classification reframes COPD staging and management. The GINA 2023 MART strategy updates asthma step therapy from the foundation. The APROCCHSS trial anchors corticosteroid use in vasopressor-dependent septic shock. These are not footnotes. They are embedded in clinical discussion because they are what certifying examiners test and what practice now requires.The teaching architecture reflects how physicians actually learn. Each chapter opens with learning objectives, integrates image prompts with clinical captions, delivers a mid-chapter board-style checkpoint, closes with a flowing summary and thirty key clinical terms, and includes fifteen USMLE and ABIM-style assessment questions, two structured clinical cases with discussion questions and pearls, and a consolidated answer key with evidence-based explanations of thirty to fifty words per question. Appendix A covers laboratory reference ranges and critical values. Appendix B provides a drug formulary with renal and hepatic dose adjustments and key drug interactions.If you are building clinical knowledge that holds up at the bedside and in the examination room, open this volume at the chapter your rotation demands most. The foundation built here carries into every year of practice that follows. Read more
