Background: The impact of multiple substance use on the risk of pancreatitis remains underexplored. Objective: To systematically review peer-reviewed observational studies assessing the association of multiple substance use with the risk of acute pancreatitis (AP) or chronic pancreatitis (CP) in adults. Design: We conducted a systematic review informed by the Preferred Reporting Items for Systematic Review and Meta-Analyses guideline. Data sources and methods: EMBASE, MEDLINE, and PsycINFO were searched up to March 2024. Reference lists of included studies were reviewed. From 5205 records identified, 181 relevant records were evaluated in full text. Studies evaluating the association of ⩾2 substances, including tobacco, alcohol, cannabis, and illicit substances, with AP or CP were included. Data were extracted by one reviewer, with quality control by a second reviewer. Quality assessments were independently conducted by two reviewers, with differences resolved by a third. Results: Of 11 included studies, 6 investigated AP as the outcome and 5 examined CP. Among AP studies, 5 comparing smoking and alcohol to alcohol-only use showed high heterogeneity ( I 2 = 90.9%), with relative risks (RRs) from 1.40 to 11.40. One study examining cannabis and alcohol versus alcohol found a lower risk of AP in cannabis users. Among CP studies, four comparing smoking and alcohol to alcohol-only use were heterogeneous ( I 2 = 81%) with odds ratios 1.21–31.50. Where examined, smoking increases the risk of AP and CP in a dose-dependent fashion. Heavy alcohol users demonstrated a significant increase in CP risk across all smoking categories in one study. Conclusion: Combined alcohol and tobacco use increases pancreatitis risk compared to single substance use, despite heterogeneity in RRs and exposure definitions. Evidence suggests a dose-dependent impact of smoking on pancreatitis risk when added to alcohol. Studies on the impact of a combination of other substance use on pancreatitis risk are needed.

Complementary and Alternative Medicine Use by Patients From the Gulf Region Seen in the International Practice of a Tertiary Care Medical Center
Background Patients from various countries may have unique patterns of using complementary and alternative medicine (CAM) and unique reasons for using it. Objective Our objective was to assess the use of CAM among patients from the Gulf region attending the Executive and International Health Program of the Department of General Internal Medicine at Mayo Clinic in Rochester, Minnesota. Methods This cross-sectional survey was administered to all patients who were from the Gulf region and were undergoing outpatient evaluation in the Executive and International Health Program. After their initial medical evaluation by a physician, the patients were invited to anonymously complete the modified International Complementary and Alternative Medicine Questionnaire. Results The survey was completed by 69 patients (41 women, 27 men; mean age, 45.4 years). The most frequently seen providers for CAM treatments were physicians (71.0% of patients), spiritual healers (29.0%), and chiropractors (20.3%). CAM treatments most frequently received from a physician were massage therapy (51.0%), hijama (38.8%), spiritual healing (24.5%), and acupuncture or herbs (16.3%). The most frequently used dietary supplements were ginger (42.0%), bee products (30.4%), and garlic (27.5%). The most common self-help therapies were prayers for health (68.1%), meditation (15.9%), and relaxation techniques (11.6%). CAM therapy, including visits to CAM providers, was used by 92.8% of patients. CAM was mainly used to improve well-being and long-term health conditions rather than for acute illnesses. Conclusion The use of CAM was high among our patients from the Gulf region, and the CAM therapies used by this population differed from the ones used by US patients. Physicians providing care to patients from the Gulf region should be aware of how the use of CAM may affect the care needs of these patients.
