A 47y/o M with HTN and dyslipidemia (LDL 3.8 mmol/L) seeks dietary advice to lower MI risk. BMI is 29 kg/m². Which dietary pattern is most strongly supported by evidence for cardiovascular risk reduction in this patient?
💡 EXPLANATION:
The Mediterranean diet has the strongest evidence (e.g., PREDIMED study) for reducing major cardiovascular events and improving lipid profiles. It emphasizes vegetables, healthy fats (olive oil), nuts, and whole grains.

A 24 y/o F presents with daily spiking fevers, severe arthralgia, and a transient salmon-colored rash on the trunk. Labs show neutrophilic leukocytosis. ANA and RF are negative. Which additional finding strongly supports the diagnosis?
💡 EXPLANATION:
The clinical picture suggests Adult-Onset Still's Disease (AOSD): quotidian fevers, evanescent salmon-pink rash, and arthralgia. A key diagnostic hallmark is extreme hyperferritinemia (often >1000 ng/mL). Autoantibodies (ANA, RF) are typically negative.

A 19y/o M presents with fever, severe fatigue, and exudative pharyngitis. O/E: Posterior cervical lymphadenopathy. Monospot test is positive. Regarding primary prevention for this condition, which statement is correct?
💡 EXPLANATION:
The diagnosis is Infectious Mononucleosis (EBV), indicated by the triad of fever, pharyngitis, and lymphadenopathy with a positive Monospot. Unlike many other viral illnesses, no vaccine is currently licensed for the prevention of EBV.
A 62y/o M with T2DM and prior MI presents for follow-up. HbA1c 7.5%, eGFR 70 mL/min. Empagliflozin is added to his regimen to reduce cardiovascular mortality. Which mechanism primarily mediates this cardioprotective effect?

A 62y/o M with T2DM and prior MI presents for follow-up. HbA1c 7.5%, eGFR 70 mL/min. Empagliflozin is added to his regimen to reduce cardiovascular mortality. Which mechanism primarily mediates this cardioprotective effect?
💡 EXPLANATION:
Empagliflozin is an SGLT2 inhibitor indicated for T2DM with established ASCVD. It acts by blocking glucose reabsorption in the proximal tubule, causing glycosuria. This leads to osmotic diuresis/natriuresis, reducing intravascular volume, preload, and afterload.

Researchers investigate the link between fire retardants and interstitial lung disease (ILD). They select 50 patients with ILD and 50 healthy matched controls to assess past exposure history. What is the most appropriate study design classification?
💡 EXPLANATION:
Participants were selected based on their disease status (ILD vs. no ILD) to look back at prior exposures. This directionality (Outcome → Exposure) is the defining characteristic of a Case-control study.

A study shows that patients screened for glioblastoma appear to survive longer than those diagnosed after symptom onset, despite no actual prolongation of life or change in disease course. Which bias best explains this result?
💡 EXPLANATION:
Lead-time bias occurs when screening detects a disease earlier than clinical presentation, artificially increasing the measured survival time (duration from diagnosis to death) without actually changing the time of death or improving outcomes.
A study finds that patients diagnosed with glioblastoma via screening MRI have a 6-week longer average survival compared to those diagnosed after symptom onset. Which type of bias most likely accounts for this difference?

A study finds that patients diagnosed with glioblastoma via screening MRI have a 6-week longer average survival compared to those diagnosed after symptom onset. Which type of bias most likely accounts for this difference?
💡 EXPLANATION:
Lead-time bias occurs when screening detects a disease earlier in its natural history than it would have presented clinically. This artificially increases the perceived survival duration (diagnosis to death) without extending actual lifespan.

An RCT of 1600 obese patients compares orlistat vs lifestyle. At the end, 120 participants had dropped out: 97 from the lifestyle arm and 23 from the combination arm. Which bias most threatens the study's validity?
💡 EXPLANATION:
Attrition bias arises from differential loss to follow-up between study arms. The unequal dropout rate (97 vs 23) undermines randomization and threatens internal validity, as dropouts may differ systematically from those who complete the study.
