Review
BACKGROUND
Diarrhea is defined as the passage of loose stools and increase in stool frequency, weight, or volume. Diarrhea is an important health issue since it accounts for 2.5 million deaths in the world each year.
SUMMARY
Diarrhea can be acute, persistent, or chronic. Acute diarrhea (AD) is usually infectious, caused by viruses, less frequently by bacteria and parasites. The majority of cases of AD are self-limiting and do not require diagnostic workup. The use of diagnostic tests in AD should be limited to patients with signs of severe dehydration, bloody stools, persistent fever and those suffering from immunodeficiencies using immunosuppressive therapy or to cases of suspected nosocomial infection. These patients should be referred to gastroenterologists or infectious disease specialists. Therapy in AD consists of early oral refeeding, antidiarrheal medications, antibiotics, and probiotics. Chronic diarrhea (CD) has diverse etiology. The majority of patients have self-limiting symptoms or functional gastrointestinal disorders. Patients with blood in stool, weight loss, clinical and laboratory signs of anemia, and palpable mass in the abdomen (red flag symptoms) need urgent gastroenterology referral. Therapy in CD is possible when the underlying cause of symptoms is identified.
KEY MESSAGES
The general practitioner should identify high-risk patients with AD and/or red flag symptoms for urgent gastroenterology referral.

Review
BACKGROUND
Abdominal pain is a common symptom of gastroenterology examination. Chronic abdominal pain is present for >3 months.
SUMMARY
Gastroesophageal reflux disease (GERD) is one of the most common gastrointestinal diseases encountered by both gastroenterologists and general practitioners. GERD is usually a chronic disease presented with a set of symptoms including heartburn and/or regurgitation, and less commonly epigastric pain. Epigastric pain syndrome is characterized by the following symptoms: epigastric pain and/or burning. It does not necessarily occur after meal ingestion, may occur during fasting, and can be even improved by meal ingestion. Duodenal ulcers tend to cause abdominal pain that is localized in the epigastric region and commence several hours after eating, often at night. Hunger provokes pain in most of the cases and decreases after meal. Gastric ulcer pain occurs immediately after eating, and consuming food increases pain. Pain is localized in the epigastrium and can radiate to the back. Abdominal pain in irritable bowel syndrome is related to defecation. A typical symptom of chronic pancreatitis is pain that radiates to the back. In Crohn's disease, inflammation causes pain. Key Messages: Pain can occur at different locations with diverse intensity and propagation and is often associated with other symptoms. For any gastroenterologist, abdominal pain is a big challenge.

Review
Surgery continues to play an important role in the therapeutic arsenal in ulcerative colitis. In acute colitis, close collaboration between the gastroenterologist and the surgeon is pertinent. Absolute indications for surgery include toxic megacolon, perforation, and severe colorectal bleeding. In addition, surgery should always be considered upon deterioration during medical therapy. The recommended operation in acute colitis is colectomy and ileostomy, with the rectum left in situ; reconstruction is not an option in the acute setting. In chronic continuous colitis, often with long-term steroid therapy, healing conditions are poor. A staged procedure is preferred also in these cases. In cases with dysplasia, surgery should be done after verifying the dysplasia since these patients often have little symptoms from their colitis. The proctocolectomy should in these cases include total mesorectal excision. Ileal pouch-anal anastomosis is the standard bowel reconstruction in ulcerative colitis. The various options should, however, always be thoroughly discussed, considering the pros and cons in each individual patient, before a choice is made. Ileorectal anastomosis is a temporary alternative in select cases (e.g. young women not having had children). Reconstructive surgery is best done approximately 6 months after primary surgery. Surgery for ulcerative colitis should be seen as complementary to medical treatment and may prevent complications, improve the patients' quality of life and occasionally be life-saving. Correct assessment and optimised medical treatment are prerequisites for surgery on accurate indications and good surgical results. Therefore, close interactions between gastroenterologists and colorectal surgeons are mandatory for optimal patient outcome.

Review
HCC is one of the most common cancers worldwide, and the third leading cause of cancer-related death globally. HCC comprises nearly 90% of all cases of primary liver cancer. Approximately half of all patients with HCC receive systemic therapy during their disease course, particularly in the advanced stages of disease. Immuno-oncology has been paradigm shifting for the treatment of human cancers, with strong and durable antitumor activity in a subset of patients across a variety of malignancies including HCC. Immune checkpoint inhibition with atezolizumab and bevacizumab, an antivascular endothelial growth factor neutralizing antibody, has become first-line therapy for patients with advanced HCC. Beyond immune checkpoint inhibition, immunotherapeutic strategies such as oncolytic viroimmunotherapy and adoptive T-cell transfer are currently under investigation. The tumor immune microenvironment of HCC has significant immunosuppressive elements that may affect response to immunotherapy. Major unmet challenges include defining the role of immunotherapy in earlier stages of HCC, evaluating combinatorial strategies that use targeting of the immune microenvironment plus immune checkpoint inhibition, and identifying treatment strategies for patients who do not respond to the currently available immunotherapies. Herein, we review the rationale, mechanistic basis and supporting preclinical evidence, and available clinical evidence for immunotherapies in HCC as well as ongoing clinical trials of immunotherapy.

Review
BACKGROUND AND AIM
Hypermobile Ehlers-Danlos syndrome (hEDS) and the hypermobility spectrum disorders (HSD) can be challenging to diagnose and manage. Gastrointestinal symptoms and disorders of gut-brain interaction are common in this cohort and multifactorial in origin. The primary aim of this review is to arm the gastroenterologist with a clinically useful understanding of HSD/hEDS, by exploring the association of gastrointestinal disorders with HSD/hEDS, highlighting current pathophysiological understanding and providing a pragmatic approach to managing these patients.
METHODS
Literature relevant to the gastrointestinal system and hypermobile Ehlers-Danlos syndrome was systematically searched, critically appraised, and summarized.
RESULTS
Diagnosis is based upon clinical criteria and a genetic basis is yet to be defined. The prevalence of many gut symptoms, including abdominal pain (69% vs 27%, P < 0.0001), postprandial fullness (34% vs 16%, P = 0.01), constipation (73% vs 16%, P < 0.001), and diarrhea (47% vs 9%, P < 0.001) are significantly higher in HSD/hEDS compared with non-HSD/hEDS individuals. Disorders of gut-brain interaction are also common, particularly functional dyspepsia. The pathophysiology of gut symptoms is poorly understood but may involve effects of connective tissue laxity and its functional consequences, and the influence of autonomic dysfunction, medication and comorbid mental health disorders. Awareness is the key to early diagnosis. Management is limited in evidence-base but ideally should include an integrated multidisciplinary approach.
CONCLUSIONS
HSD/hEDS is a multisystemic disorder in which gastrointestinal symptoms, particularly related to disorders of gut-brain interaction are common. Deficiencies in knowledge regarding the pathophysiological processes limit evidence-based interventions and remain important areas for future research.

Review
BACKGROUND & AIMS
Over several decades, changes in health care have negatively impacted meaningful communication between the patient and provider and adversely affected their relationship. Under increasing time pressure, physicians rely more on technology than face-to-face time gathering data to make clinical decisions. As a result, they find it more challenging to understand the illness context and fully address patient needs. Patients experience dissatisfaction and a diminution of their role in the care process. For patients with disorders of gut-brain interaction, stigma leads to greater care dissatisfaction, as there is no apparent structural basis to legitimize the symptoms. Recent evidence suggests that practical communication skills can improve the patient-provider relationship (PPR) and clinical outcomes, but these data are limited.
METHODS
The Rome Foundation convened a multidisciplinary working team to review the scientific evidence with the following aims: a) to study the effect of communication skills on patient satisfaction and outcomes by performing an evidence-based review; b) to characterize the influence of sociocultural factors, health care system constraints, patient perspective, and telehealth on the PPR; c) to review the measurement and impact of communication skills training on these outcomes; and d) to make recommendations to improve communication skills training and the PPR.
RESULTS
Evidence supports the fact that interventions targeting patient-provider interactions improve population health, patient and provider experience, and costs. Communication skills training leads to improved patient satisfaction and outcomes. The following are relevant factors to consider in establishing an effective PPR: addressing health care system constraints; incorporating sociocultural factors and the role of gender, age, and chronic illness; and considering the changing role of telehealth on the PPR.
CONCLUSIONS
We concluded that effective communication skills can improve the PPR and health outcomes. This is an achievable goal through training and system change. More research is needed to confirm these findings.

BACKGROUND
Chronic diarrhea is defined as more than 3 bowel movements per day, or loose stools, or stool weight >200 g/day for at least 4 weeks. Accompanying symptoms may include urgency, abdominal pain, or cramps.
SUMMARY
A number of causes have to be considered, including inflammatory, neoplastic, malabsorptive, infective, vascular, and functional gastrointestinal diseases. Other causes include food intolerances, side effects of drugs, or postsurgical conditions. Diarrhea may also be symptom of a systemic disease, like diabetes or hyperthyroidism. Special patient groups, like the very elderly and immunocompromised patients, pose special challenges. This review follows a question-answer style and addresses questions raised on the intersection of primary and secondary care. What do you mean by diarrhea? Why is it important to distinguish between acute or chronic diarrhea? How shall the patient with chronic diarrhea be approached? How can history and physical exam help? How can routine laboratory tests help in categorizing diarrhea? Which additional laboratory tests may be helpful? How to proceed in undiagnosed or intractable diarrhea? What are the treatment options in patients with chronic diarrhea? Key Messages: Acute diarrhea is usually of infectious origin with the main treatment goal of preventing water and electrolyte disturbances. Chronic diarrhea is usually not of infectious origin and may be the symptom of a large number of gastrointestinal and general diseases or drug side effects. In undiagnosed or intractable diarrhea, the question shall be raised whether the appropriate tests have been performed and interpreted correctly.

Review
BACKGROUND
Anemia is present in almost 5% of adults worldwide and accompanies clinical findings in many diseases. Diseases of the gastrointestinal (GI) tract and liver are a common cause of anemia, so patients with anemia are often referred to a gastroenterologist.
SUMMARY
Anemia could be caused by various factors such as chronic bleeding, malabsorption, or chronic inflammation. In clinical practice, iron deficiency anemia and the combined forms of anemia due to different pathophysiological mechanisms are most common. Esophagogastroduodenoscopy, colonoscopy, and the small intestine examinations in specific situations play a crucial role in diagnosing anemia. In anemic, GI asymptomatic patients, there are recommendations for bidirectional endoscopy. Although GI malignancies are the most common cause of chronic bleeding, all conditions leading to blood loss, malabsorption, and chronic inflammation should be considered. From a gastroenterologist's perspective, the clinical spectrum of anemia is vast because many different digestive tract diseases lead to bleeding. Key Messages: The gastroenterological approach in solving anemia's problem requires an optimal strategy, consideration of the accompanying clinical signs, and the fastest possible diagnosis. Although patients with symptoms of anemia are often referred to gastroenterologists, the diagnostic approach requires further improvement in everyday clinical practice.

Review
Advances in the field of endoscopy have allowed gastroenterologists to obtain detailed imaging of anatomical structures and to treat gastrointestinal diseases with endoscopic therapies. However, these technological developments have exposed endoscopists and staff to hazards such as musculoskeletal injuries, exposure to infectious agents, and ionizing radiation. We aimed to review the occupational hazards for the gastroenterologist and endoscopist. Using PubMed, Medline, Medscape, and Google Scholar, we identified peer-reviewed articles with the keywords "occupational hazards," "health hazards," "occupational health hazards," "endoscopy," "gastroenterologist," "infectious agents," "musculoskeletal injuries," and "radiation." Strategies for reducing exposure to infectious agents, radiation, and the risk of musculoskeletal injuries related to gastroenterology include compliance with established standard measures, the use of thyroid shields and radioprotective eyewear, and ergonomic practices. We conclude that educating endoscopic personnel and trainees in these practices, in addition to further research in these areas, will likely lead to the development of more efficient and user-friendly workspaces that are safer for patients and personnel.

Review
BACKGROUND
Available data suggest that the prevalence of chronic liver disease (CLD) and primary liver cancer is rising in Europe and represents a major public health problem. Predictions are showing that these trends will continue to rise in the upcoming years.
SUMMARY
Alcohol-related liver disease, nonalcohol fatty liver disease, and viral hepatitis B and hepatitis C are the leading causes of liver cirrhosis and primary liver cancer in Europe. Drug-induced liver injury represents a major cause of acute hepatitis, while liver transplantation is the second most common solid organ transplantation in the world. Patients with CLD have increasing rates of hospitalization, longer hospital stays, and more adverse outcomes compared to the other chronic conditions. Direct targeting of risk factors can prevent complications of advanced liver disease and improve outcome. Patients with CLD should be referred to a hepatologist for assessment of the stage of liver disease, for specific treatment and screening for hepatocellular carcinoma. Moreover, patients with unknown etiology of abnormal liver blood tests should be referred to a hepatologist for assessment of liver disease, as well as for prevention and treatment of complications of cirrhosis and/or portal hypertension. Key Messages: CLD is amenable to prevention and treatment, while disease management strategies need to improve in order to reduce the burden of liver disease and deaths due to end-stage liver diseases.
