Exposure to air pollutants, particularly ozone, was associated with amodest increased risk of developing appendicitis. Notably, the effect of airpollution was strongest during the summer months, when people were more likelyto be outside.

- Metabolic Syndrome Ups Colorectal Cancer Risk

In a large population-based study, metabolic syndrome patients had a 75percent higher risk of colorectal cancer compared to those without metabolicsyndrome.

- Parents Foster Significant Misperceptions of Children's Weight andOften Misjudge Risk for Obesity in Adulthood

Results of a survey revealed most parents do not perceive their childrenas overweight or at risk for adulthood obesity. Even though all the childrenhad elevated BMI, less than 13 percent of the parents reported their child ascurrently overweight. Fewer than one-third perceived that their child's riskfor adult obesity was above average or very high.

- Screening for Colorectal Cancer Before Medicare Age Could Save Millionsin Federal Health Care Dollars

A new study suggests a screening program for colon cancer in patientsstarting ten years prior to Medicare eligibility, at age 55 instead ofMedicare's 65, would save at least two dollars for every dollar spent.

- New Studies Examine the Effectiveness of Probiotics in IBS

Several studies highlight the safety and efficacy of probiotics inimproving symptoms and normalizing bowel movement frequency in patientssuffering from constipation or diarrhea related to Irritable Bowel Syndrome.

- New Study Finds Summer is Peak Season for Diagnosis of EsophagusDisorder

Two new studies examined eosinophilic esophagitis, a condition that canmimic symptoms of GERD, in a small proportion of people. The first study foundthat the diagnosis of EoE peaked during the summer months. The second analysisreviewed a case series of heartburn patients who underwent surgery to treatGERD, but who were found later actually to suffer from EoE.

- Women Require Less Tobacco Exposure than Men to Increase Colon CancerRisk

While smoking poses a health threat to both men and women, women requireless tobacco exposure than men to have a significant increased risk forcolorectal neoplasia. In a separate analysis, researchers found smoking mayincrease the risk of pancreatic cancer precursor lesions, particularly inpatients with a strong family history of the disease.

- Endoscopic Therapy May Offer an Alternative to Surgery for Patientswith Barrett's Esophagus, Early Stage Esophageal Cancer

Two separate studies suggest endoscopic mucosal resection, or EMR, is aneffective treatment alternative to surgery and generally yields positivelong-term results for patients with Barrett's esophagus or early stageesophageal cancer.

- New Therapeutic Treatment Approach Improves Survival in EsophagealCancer Patients

A new therapeutic treatment, when delivered endoscopically and used incombination with chemotherapy and radiation therapy, improved survival ratesin patients with locally advanced esophageal cancer.

- Studies Highlight the Importance of Bowel Prep and Effectiveness ofColonoscopy in Detecting Potentially Dangerous Polyps

New research emphasizes the importance of adequate bowel preparation priorto colonoscopy, and highlights the remarkable effectiveness of colonoscopy indetecting and removing pre-cancerous polyps, particularly tiny, flat,potentially pre-cancerous growths in the colon known as "sessile serratedadenomas," that may go undetected or unreported by other colorectal cancerscreening methods.
