• A biomarker-stratified comparison of top-down versus accelerated step-up treatment strategies for patients with newly diagnosed Crohn's disease (PROFILE): a multicentre, open-label randomised controlled trial

  ˜The œLancet. Gastroenterology & hepatology · 2024 · 252 citations

  BACKGROUND: Management strategies and clinical outcomes vary substantially in patients newly diagnosed with Crohn's disease. We evaluated the use of a putative prognostic biomarker to guide therapy by assessing outcomes in patients randomised to either top-down (ie, early combined immunosuppression with infliximab and immunomodulator) or accelerated step-up (conventional) treatment strategies. METHODS: PROFILE (PRedicting Outcomes For Crohn's disease using a moLecular biomarker) was a multicentr…

• Impact of opioid-free analgesia on pain severity and patient satisfaction after discharge from surgery: multispecialty, prospective cohort study in 25 countries

  British journal of surgery · 2024 · 12 citations

  BACKGROUND: Balancing opioid stewardship and the need for adequate analgesia following discharge after surgery is challenging. This study aimed to compare the outcomes for patients discharged with opioid versus opioid-free analgesia after common surgical procedures. METHODS: This international, multicentre, prospective cohort study collected data from patients undergoing common acute and elective general surgical, urological, gynaecological, and orthopaedic procedures. The primary outcomes were…

• The Nonstationary Newsvendor with (and Without) Predictions

  Manufacturing & Service Operations Management · 2025-03-04 · 2 citations

  article

  Problem definition: The classic newsvendor model yields an optimal decision for a “newsvendor” selecting a quantity of inventory under the assumption that the demand is drawn from a known distribution. Motivated by applications such as cloud provisioning and staffing, we consider a setting in which newsvendor-type decisions must be made sequentially in the face of demand drawn from a stochastic process that is both unknown and nonstationary. All prior work on this problem either (a) assumes that…

• Why Consumers Boycott More Than Buycott: The Role of Perceived Instrumentality and Self-Enhancement

  Journal of the Association for Consumer Research · 2024 · 2 citations

  1st authorCorresponding

  Consumers can voice their values by avoiding purchase from brands that oppose their values (boycotting) or deliberately purchasing from brands that support their values (buycotting). Prior literature has found that consumers are more likely to boycott than to buycott, but it has not yet provided a clear answer to why this is the case. Drawing from the literature on boycotting, we argue that this difference is, in part, because consumers perceive boycotting versus buycotting: (1) to be more instr…
