Abstract
The etiopathogenesis of diverticulitis, among the most common gastrointestinal diagnoses, remains largely unknown. By leveraging stool collected within a large prospective cohort, we performed shotgun metagenomic sequencing and untargeted metabolomics profiling among 121 women diagnosed with diverticulitis requiring antibiotics or hospitalizations (cases), matched to 121 women without diverticulitis (controls) according to age and race. Overall microbial community structure and metabolomic profiles differed in diverticulitis cases compared to controls, including enrichment of pro-inflammatory Ruminococcus gnavus, 1,7-dimethyluric acid, and histidine-related metabolites, and depletion of butyrate-producing bacteria and anti-inflammatory ceramides. Through integrated multi-omic analysis, we detected covarying microbial and metabolic features, such as Bilophila wadsworthia and bile acids, specific to diverticulitis. Additionally, we observed that microbial composition modulated the protective association between a prudent fiber-rich diet and diverticulitis. Our findings offer insights into the perturbations in inflammation-related microbial and metabolic signatures associated with diverticulitis, supporting the potential of microbial-based diagnostics and therapeutic targets.

Abstract
Acute colonic diverticulitis is a gastrointestinal condition that is frequently encountered by primary care and emergency department practitioners, hospitalists, surgeons, and gastroenterologists. Clinical presentation ranges from mild abdominal pain to peritonitis with sepsis. It is often diagnosed on the basis of clinical features alone, but imaging is necessary in more severe presentations to rule out such complications as abscess and perforation. Treatment depends on the severity of the presentation, the presence of complications, and underlying comorbid conditions. Medical and surgical treatment algorithms are evolving. This article provides an evidence-based, clinically relevant overview of the epidemiology, diagnosis, and treatment of acute diverticulitis.

Abstract
The colon is the largest hormonally active tissue in the human body. It has been known for over a hundred years that various hormones and bioactive peptides play important roles in colon function. More recently there is a growing interest in the role the sex steroids, oestrogens and androgens, may play in both normal colon physiology and colon pathophysiology. In this review, we examine the potential role oestrogens and androgens play in the colon. The metabolism and subsequent action of sex steroids in colonic tissue is discussed and how these hormones impact colon motility is investigated. Furthermore, we also determine how oestrogens and androgens influence colorectal cancer incidence and development and highlight potential new therapeutic targets for this malignancy. This review also examines how sex steroids potentially impact the severity and progression of other colon disease, such as diverticulitis, irritable bowel syndrome, and polyp formation.

Abstract
There have been considerable advances in the treatment of diverticular disease in recent years. Antibiotics are frequently used to treat symptoms and prevent complications. Rifaximin, a non-absorbable antibiotic, is a common therapeutic choice for symptomatic diverticular disease in various countries, including Italy. Because of its low systemic absorption and high concentration in stools, it is an excellent medicine for targeting the gastrointestinal tract, where it has a beneficial effect in addition to its antibacterial properties. Current evidence shows that cyclical rifaximin usage in conjunction with a high-fiber diet is safe and effective for treating symptomatic uncomplicated diverticular disease, while the cost-effectiveness of long-term treatment is unknown. The use of rifaximin to prevent recurrent diverticulitis is promising, but further studies are needed to confirm its therapeutic benefit. Unfortunately, there is no available evidence on the efficacy of rifaximin treatment for acute uncomplicated diverticulitis.

Frequency of Bowel Movements and Risk of Diverticulitis. Clin Gastroenterol Hepatol 2022; 20:325-333.e5.

Abstract
OBJECTIVE The etiology of diverticulitis is poorly understood. The long-held belief that constipation and low-fiber diet are risk factors for diverticulosis has recently been challenged by studies that suggest that more frequent bowel movements predispose to diverticulosis. We aim to prospectively explore the association between bowel movement frequency and incident diverticulitis. DESIGN We studied participants of the Nurses' Health Study (NHS) and Health Professional Follow-up Study (HPFS). Participants' medical history, lifestyle factors and diet were used in Cox proportional hazards regression models to estimate multivariable-adjusted hazard ratios(HRs) and 95% confidence intervals(CI). RESULTS In the NHS during over 24 years of follow-up encompassing 1,299,922 person-years, we documented 5,214 incident cases of diverticulitis, and in the HPFS over 14 years encompassing 368,661 person-years of follow-up, we documented 390 incident cases of diverticulitis. We observed an inverse association between the frequency of bowel movements and risk of diverticulitis. In the NHS, compared with women who had daily bowel movements, those with more than once daily bowel movements had a HR of 1.30 (95% CI, 1.19, 1.42) and those with less frequent bowel movements had a HR of 0.89 (95% CI, 0.82, 0.95; p-trend < 0.0001). In the HPFS, the corresponding HRs were 1.29 (95% CI, 1.04, 1.59) and 0.61 (95% CI, 0.36, 1.03; p-trend = 0.003). The association between bowel movements and diverticulitis was not modified by categories of age, BMI, physical activity, laxative use or fiber intake. CONCLUSION More frequent bowel movements appear to be a risk factor for subsequent diverticulitis both in men and women. Further studies are needed to understand the potential mechanisms that may underlie this association.

Abstract
Left sided colonic diverticulitis is a common and costly gastrointestinal disease in Western countries, characterized by acute onset of often severe abdominal pain. Imaging is necessary to make an initial diagnosis and determine disease severity. Colonoscopy should be done six to eight weeks after diagnosis to rule out a missed colon malignancy. Antibiotic treatment is used selectively in immunocompetent patients with mild acute uncomplicated diverticulitis. The clinical course of diverticulitis commonly includes unpredictable recurrences and chronic gastrointestinal symptoms, which are a detriment to quality of life. A better understanding of prognosis has prompted a shift toward non-operative approaches. The decision to undergo prophylactic colon resection should be individualized to consider the severity of diverticulitis, the patient's health and immune status, and the patient's preferences and values, as well as benefits and risks. Because only a section of colon is removed, recurrent diverticulitis remains a risk. Acute diverticulitis with an abscess is treated with antibiotics that cover Gram negative and anaerobic bacteria, with or without percutaneous drainage. Acute diverticulitis with purulent or feculent contamination of the peritoneal cavity is managed with surgery; primary resection and anastomosis is the procedure of choice in stable patients.

Abstract
Colonic diverticulitis is a painful gastrointestinal disease that recurs unpredictably and can lead to chronic gastrointestinal symptoms. Gastroenterologists commonly care for patients with this disease. The purpose of this Clinical Practice Update is to provide practical and evidence-based advice for management of diverticulitis. We reviewed systematic reviews, meta-analyses, randomized controlled trials, and observational studies to develop 14 best practices. In brief, computed tomography is often necessary to make a diagnosis. Rarely, a colon malignancy is misdiagnosed as diverticulitis. Whether patients should have a colonoscopy after an episode of diverticulitis depends on the patient's history, most recent colonoscopy, and disease severity and course. In patients with a history of diverticulitis and chronic symptoms, alternative diagnoses should be excluded with both imaging and lower endoscopy. Antibiotic treatment can be used selectively rather than routinely in immunocompetent patients with mild acute uncomplicated diverticulitis. Antibiotic treatment is strongly advised in immunocompromised patients. To reduce the risk of recurrence, patients should consume a high-quality diet, have a normal body mass index, be physically active, not smoke, and avoid nonsteroidal anti-inflammatory drug use except aspirin prescribed for secondary prevention of cardiovascular disease. At the same time, patients should understand that genetic factors also contribute to diverticulitis risk. Patients should be educated that the risk of complicated diverticulitis is highest with the first presentation. An elective segmental resection should not be advised based on the number of episodes. Instead, a discussion of elective segmental resection should be personalized to consider severity of disease, patient preferences and values, as well as risks and benefits.

Abstract
Objectives: Diverticular disease of the colon is a pathology that arises from outward ballooning of the mucosa due to some weakness in the muscle layer. Diverticular disease may range from symptomatic uncomplicated diverticular disease to symptomatic disease with complications, such as acute diverticulitis or diverticular bleeding. Acute colonic diverticulitis occurs in about 10- 25% of patients. Methods: In this study, 134 patients who were admitted to our emergency clinic with complaints of abdominal pain between 2016-2019 and hospitalized with the diagnosis of acute diverticulitis were included. Patients’ sex, age, presence of additional disease, increase in leukocyte and C-reactive protein (CRP), localization of diverticulitis, Hinchey classification, mean length of hospital stay and treatment were evaluated. The effects of these parameters on complications and recurrence were statistically analyzed. Results: The length of hospital stay was statistically significantly associated positively with the Hinchey classification (p<0.001). While 18 patients who were medically treated developed recurrence later, and this rate was statistically significant (p<0.001). When one of the factors, localization, which may play a role in the severity of the disease and recurrence are examined, was evaluated concerning its results in our study, we found that rectosigmoid location is an important factor for recurrence. We found that the localization in the colon and the severity of the disease were effective in the prognosis of acute diverticulitis. Conclusion: We believe that localization and the severity of the disease should be taken into consideration when planning surgery in these patients.

Abstract
BACKGROUND & AIMS Microscopic colitis is one of the most common causes of chronic diarrhea in older populations. We investigated all-cause and cause-specific mortality in patients with microscopic colitis. METHODS We conducted a nationwide cohort study of all cases of microscopic colitis (n = 14,333) diagnosed from 1990 through 2017 in Sweden. Cases of microscopic colitis were identified using SNOMED codes from gastrointestinal histopathology reports collected from Sweden's 28 pathology departments. Each case of microscopic colitis was matched to 5 population comparators (n = 68,700). Mortality data were ascertained from Sweden's cause of death register. We used Cox proportional hazards modeling to estimate adjusted hazard ratios (aHRs) and 95% CIs. RESULTS Through December of 2017, we confirmed 3014 deaths in patients with microscopic colitis (27.4/1000 person-years) and 12,534 deaths in matched population comparators (23.3/1000 person-years). This corresponded to a 10-year absolute risk difference of 3.4% (95% CI, 2.1%-4.6%) and an aHR of 1.17 (95% CI, 1.12-1.22). However, further adjustment of models for comorbidity burden reduced the relative risk of death for patients with microscopic colitis (aHR, 0.98; 95% CI, 0.94-1.02). In analyses of cause-specific death, microscopic colitis was associated with an increased risk of gastrointestinal-related death (aHR, 1.68; 95% CI, 1.38-2.05) and infection-related death (aHR, 1.42 ; 95% CI, 1.11-1.83), but not cancer-related death (aHR, 0.83; 95% CI, 0.76-0.91) or cardiovascular-related death (aHR, 1.02; 95% CI, 0.96-1.10). CONCLUSIONS In a nationwide cohort study in Sweden, we found that patients with microscopic colitis were at increased risk of death. However, the increase appears to be related to higher burden of comorbidities in this population.

Abstract
Diverticula are outpouchings of the intestinal wall and are common anatomical alterations detected in the human colon. Colonic diverticulosis (the presence of diverticula in the colon; referred to as diverticulosis) remains asymptomatic in most individuals but ~25% of individuals will develop symptomatic diverticulosis, termed colonic diverticular disease (also known as diverticular disease). Diverticular disease can range in severity from symptomatic uncomplicated diverticular disease (SUDD) to symptomatic disease with complications such as acute diverticulitis or diverticular haemorrhage. Since the early 2000s, a greater understanding of the pathophysiology of diverticulosis and diverticular disease, which encompasses genetic alterations, chronic low-grade inflammation and gut dysbiosis, has led to improvements in diagnosis and management. Diagnosis of diverticular disease relies on imaging approaches, such as ultrasonography, CT and MRI, as biomarkers alone are insufficient to establish a diagnosis despite their role in determining disease severity and progression as well as in differential diagnosis. Treatments for diverticular disease include dietary fibre, pharmacological treatments such as antibiotics (rifaximin), anti-inflammatory drugs (mesalazine) and probiotics, alone or in combination, and eventually surgery. Despite being effective in treating primary disease, their effectiveness in primary and secondary prevention of complications is still uncertain.

Abstract
BACKGROUND & AIMS Obesity has been associated with an increased risk of colonic diverticulosis. Evidence for this association is limited. We assessed whether anthropometric measures of obesity were associated with colonic diverticulosis. METHODS We analyzed data from a prospective study of 623 patients undergoing screening colonoscopies from 2013 through 2015; colonoscopies included examinations for diverticulosis. Body measurements were made the day of the procedure. Multivariate analyses were performed using modified Poisson regression to estimate prevalence ratios (PRs) and 95% CIs while adjusting for confounding variables. All analyses were stratified by sex. RESULTS Among men, there was no association between any measure of obesity and diverticulosis. After adjustment, women with an obese body mass index (BMI ≥ 30) had an increased risk of any diverticulosis (PR, 1.48; 95% CI, 1.08-2.04) compared with women with a normal body mass index (BMI 18.5-24.9). The strength of this association was greater for more than 5 diverticula (PR, 2.05; 95% CI, 1.23-3.40). There was no significant association between measures of central obesity and diverticulosis in women. Stratified by sex, colonic diverticulosis was significantly less prevalent in women compared with men before the age of 51 years (29% vs 45%, P = .06). The prevalence of diverticulosis did not differ by sex in older age groups. CONCLUSIONS In an analysis of data from 623 patients undergoing screening colonoscopies, we found that obesity (BMI ≥30) significantly increased the risk of colonic diverticulosis in women but not men. Colonic diverticulosis was less prevalent in premenopausal-age women compared with similar-age men. These findings suggest that sex hormones may influence the development of diverticulosis.

Abstract
OBJECTIVES Although low fiber intake has been considered a risk factor for diverticulitis, prospective evidence is limited in women despite having a disproportionate burden of disease, with little known about variation in the protective effects according to food sources. We assessed the associations of intakes of fiber and major food sources of fiber including fruits and vegetables with risk of diverticulitis in a large cohort of women. METHODS We followed 50,019 women in the Nurses' Health Study (1990-2014) who were aged 43-70 years and free of diverticulitis, cancer, and inflammatory bowel disease at baseline. Incident diverticulitis was identified through self-report with validity confirmed by review of medical records. RESULTS We documented 4,343 incident cases of diverticulitis, encompassing 1,106,402 person-years of follow-up. Compared with participants in the lowest quintile, the multivariable hazard ratio of diverticulitis in the highest quintile of total fiber intake was 0.86 (95% confidence interval: 0.78-0.95; P-trend = 0.002). Fiber from fruits and cereals, but not vegetables, was associated with a decreased risk of diverticulitis. Furthermore, intake of total whole fruit intake and specific fruits such as apples/pears and prunes were associated with reduced risk of diverticulitis with a multivariable hazard ratio for diverticulitis of 0.95 (0.92-0.98; P-trend < 0.001) for every serving increase of total whole fruit intake per day. DISCUSSION Higher intake of dietary fiber and fiber from different food sources, except for vegetable fiber, are associated with a lower risk of diverticulitis in women. A greater intake of whole fruit is also associated with reduced risk.

Abstract
This article reviews epidemiological evidence of heritability and putative mechanisms in diverticular disease, with greatest attention to 3 recent studies of genetic associations with diverticular disease based on genome-wide or whole-genome sequencing studies in large patient cohorts. We provide an analysis of the biological plausibility of the significant associations with gene variants reported and highlight the relevance of ANO1, CPI-17 (aka PPP1R14A), COLQ6, COL6A1, CALCB or CALCA, COL6A1, ARHGAP15, and S100A10 to colonic neuromuscular function and tissue properties that may result in altered compliance and predispose to the development of diverticular disease. Such studies also identify candidate genes for future studies.
