Abstract
The burden of inflammatory bowel disease (IBD) in older adults (ie, aged over 60 years old) is increasing due to a combination of an ageing population with compounding prevalence of IBD and increasing incidence of elderly-onset (ie, onset over the age of 60 years) IBD. Despite the increasing prevalence of IBD, there is a paucity of evidence on which to base management of older adults with IBD, leading to substantial variability in care. This population is under-represented in clinical trials and has a high burden of chronic corticosteroid use, low uptake of steroid-sparing immunosuppressive agents, and high rates of unplanned health-care use and disability. Management of IBD in older adults requires carefully weighing an individual patient's risk of IBD-related complications, IBD-directed immunosuppressive therapy, and non-IBD comorbidities. A deeper understanding of biological and functional age, dynamic risk stratification strategies (including frailty-based risk assessment tools), comparative effectiveness and safety of current therapies and treatment strategies, and shared decision making to inform treatment goals and targets is needed to improve outcomes in older adults with IBD. In this Review, we discuss the epidemiology, natural history, pathophysiology, and medical and surgical management of older individuals living with IBD and identify key research gaps and approaches to address them.

Utilization of health belief model in comprehending diarrheal disease dynamics: a case of cryptosporidiosis in Uganda. BMC Public Health 2022; 22:2008. [PMID: 36324178 PMCID: PMC9628109 DOI: 10.1186/s12889-022-14413-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/22/2022] [Accepted: 10/21/2022] [Indexed: 11/06/2022] Open
Abstract
BACKGROUND Diarrheal diseases contribute greatly to the reported global childhood mortality and morbidity with related social, economic consequences. This study was conducted to analyze the utilization of the Health Belief Model (HBM) theory to comprehend diarrheal disease dynamics in Uganda. METHODS Our study utilized a qualitative cross-sectional design among adult livestock farmers in selected farming communities. A total of 80 individuals were recruited and interviewed through Focus Discussion Groups (FDGs) (n = 6) and Key Informant Interviews (KIIs) (n = 8) to evaluate diarrheal disease dynamics. The scope of dynamics included but not limited to exposure risks, knowledge, and attitudes. Our results were presented using the five (5) constructs of the HBM. RESULTS Perceived susceptibility; communities believed that both humans and their animals are at high risk of different kinds of diarrheal infections. The farmers believed that majority of these diarrhea infections are hard to treat especially among animals. Perceived severity; farmers believed that diarrheal diseases are characterized by loss of weight, fever, emaciation, dry eyes, severe prolonged diarrhea and sudden death. Perceived barriers; limited knowledge and misconceptions about the diarrheal infections were great inhibitors to successful disease prevention and control. Self-efficacy; farmers had fear of laxity that interventions being suggested and put in place to curb diarrheal diseases such as cryptosporidiosis would wither away with time thus endemicity of the problem in the community. Modifying factors and cues to action; most of the farmers treat animals by themselves based on; probability, traditional knowledge and previous experience. CONCLUSION Sustained public health interventional activities should therefore be undertaken by both human and animal health sectors with maximum community involvement. Communities suggested the need to increase preventive measures and promote household hygiene efforts to always wash hands with soap and running water in order to reduce the burden of diarrhea diseases such as cryptosporidiosis.

Global estimated Disability-Adjusted Life-Years (DALYs) of diarrheal diseases: A systematic analysis of data from 28 years of the global burden of disease study. PLoS One 2021; 16:e0259077. [PMID: 34705878 PMCID: PMC8550424 DOI: 10.1371/journal.pone.0259077] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/16/2020] [Accepted: 10/12/2021] [Indexed: 02/04/2023] Open
Abstract
BACKGROUND Diarrheal disease (DD)-associated mortality has declined since 1990; however, the incidence of DD has experienced a less-pronounced decrease. Thus, it is important to track progress in managing DD by following loss of healthy years. A disability-adjusted life-year (DALY), which combines data on years-of-life lost (YLL) and years-lived with-disability (YLD), is a metric that can track such a burden. METHODS AND FINDINGS Using all 28 years of data in the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2017, we compared DD DALYs among different demographic subsets including sex, age, country, and World Bank (WB) income level. We also evaluated DD DALYs as a function of the socio-demographic index (SDI), a measure of a region's socio-demographic development. On a global level, DD DALYs have decreased by approximately 85.43% from 1990 to 2017. Incidence and prevalence have decreased by 1.53% and 4.45%, respectively. A dramatic decrease in DD DALYs were observed for WB low-income countries, but not for WB high-income constituents. The temporal decrease in DD DALY rates in WB low-income countries was likely driven by a decrease in YLL. Alternatively, temporal increases in both YLL and YLD may have contributed to the apparent lack of progress in WB high-income countries. Regardless of WB income classification, children under the age of five and the elderly were the most vulnerable to DD. In nearly every year from 1990 to 2017, DD DALYs for females were higher than those for males in WB high-income regions, but lower than those for males in WB low-income constituents. The reason for these differences is not known. We also observed that the rate of DD DALYs was highly correlated to SDI regardless of WB income classification. CONCLUSIONS To the best of our knowledge, this is the only temporal study of DD DALYs that encompasses all 28 years of data available from the GBD. Overall, our analyses show that temporal reductions in DD DALYs are not equivalent across regions, sexes and age groups. Therefore, careful attention to local and demography-specific risk factors will be necessary to tailor solutions in region- and demography-specific manners.

Abstract
Infections in elderly patients can prove diagnostically challenging. Age-related factors affecting the immune system in older individuals contribute to nonspecific presentations. Other age-related factors and chronic conditions have symptoms that may or may not point to an infectious diagnosis. Delay in administration of antimicrobials can lead to poor outcomes; however, unnecessary administration of antimicrobials can lead to increased morbidity and contribute to the emergence of multidrug-resistant organisms. Careful clinical assessment and consideration of patient history and risk factors is crucial. When necessary, antimicrobials should be chosen that are appropriate for the diagnosis and deescalated as soon as possible.

Abstract
BACKGROUND The early detection of enteric infections in older adults is challenging because typical signs and symptoms of disease may be less common, absent, or overlooked. Understanding illness characteristics of enteric infections among older adults could improve the timeliness and accuracy of clinical diagnoses, thereby improving patient outcomes and increasing cases reported to surveillance. METHODS Here, we describe illness characteristics (percentage reporting bloody diarrhea, fever, vomiting, abdominal pain; percentage hospitalized; duration of hospitalization; and duration of illness) among older adults (≥65 years) with acute gastroenteritis and culture-confirmed Campylobacter and nontyphoidal Salmonella infections in Australia, Canada, and the United States and compare these characteristics with those among younger people (<5 years, 5-24 years, and 25-64 years). RESULTS A significant negative correlation was found between all symptoms and increasing age group, except for bloody diarrhea in cases of acute gastroenteritis. Adults aged ≥85 years reported bloody diarrhea in only 9% of nontyphoidal Salmonella and 4% of Campylobacter infections compared with 59% and 55% among children aged <5 years. Conversely, a greater percentage of older adults (≥65) than younger persons (<5, 5-24, 25-64) reported being hospitalized, with an increasing linear relationship in age groups 65 years and older. CONCLUSIONS Although older adults are more likely to have severe illness and be hospitalized, we found that the proportion of persons reporting symptoms typically associated with enteric infections decreases with age. These findings have implications for clinical recognition and treatment of gastrointestinal illness, as well as for public health research.

Abstract
This report describes a frail 92-year-old woman with dementia who presented with a year's history of chronic watery non-bloody diarrhoea. She had abdominal bloating, weight loss, faecal urgency, nocturnal stools and developed faecal incontinence. Her serum C reactive peptide and faecal calprotectin were elevated. Flexible sigmoidoscopy was macroscopically normal, but demonstrated histological features of microscopic colitis (MC) in sigmoid colon and rectal biopsies. Polypharmacy was reviewed for possible medication-induced MC. Ranitidine, donepezil and simvastatin were discontinued. She was started on oral budesonide with improvement in the abdominal and bowel symptoms. Stool frequency and consistency normalised, and the faecal incontinence resolved with treatment. The outcomes were an improved quality of life, reduced functional dependency, reduced carer strain and avoidance of premature transition from her home into a long-term/institutional care setting. We briefly review terminology, basic epidemiology, notable associations, the importance of establishing a diagnosis and some treatment considerations for MC.

Abstract
Background Acute infectious diarrhea (AID) is a commonly observed condition globally. Several studies recommend against the use of empiric antibiotic therapy for AID, except in some cases of travelers' diarrhea. However, many physicians prescribe antimicrobial agents for AID. We aimed to determine the rate of antibiotic use and the associated prescription patterns among adults with AID. Materials and Methods This population-based, retrospective epidemiological study was performed using Korean National Health Insurance claims data from 2016 to 2017. The study population comprised adults (age ≥18 years) who had visited clinics with AID-related complaints. Exclusion criteria were the presence of Crohn's disease, ulcerative colitis, irritable bowel syndrome, and other non-infectious forms of colitis. Patients who underwent surgery during admission were also excluded. Results The study population comprised 1,613,057 adult patients with AID (767,606 [47.6%] men). Young patients (age 18 – 39 years) accounted for 870,239 (54.0%) of the study population. Overall, 752,536 (46.7%) cases received antibiotic prescriptions. The rate of antibiotic administration tended to be higher among elderly patients (age ≥65 years) than among younger patients (49.5% vs. 46.4%, P <0.001). The antibiotics most frequently prescribed in both monotherapy and combination regimens were fluoroquinolones (29.8%), rifaximin (26.8%), second-generation cephalosporins (9.2%), third-generation cephalosporins (7.3%), trimethoprim/sulfamethoxazole (5.5%), and β-lactam/β-lactamase inhibitors (5.3%). Patients who visited tertiary care hospitals had lower rates of antibiotic therapy (n = 14,131, 41.8%) than did those visiting private clinics (n = 532,951, 47.1%). In total, 56,275 (62.3%) admitted patients received antibiotic therapy, whereas outpatients had lower rates of antibiotic prescription (n = 694,204, 46.0%). Conclusion This study revealed differences between the antibiotics used to treat AID in Korea and those recommended by the guidelines for AID treatment. Multifaceted efforts are necessary to strengthen physicians' adherence to published guidelines.

Abstract
PURPOSE The objectives of the epidemiological investigation were to describe factors associated with prolonged transmission of acute gastroenteritis in a nursing home during a norovirus outbreak. METHODS A retrospective cohort study was conducted among residents (N = 89) and staff members (N = 86) of the nursing home. Outbreak description was performed in both residents and staff members. Among residents, attack rates and relative risks and their 95% confidence interval (95% CI) associated with different identified risk factors including consumption of normal, mixed and choped meal, score of dependency were calculated. A multivariate logistic regression model was fitted to assess the independent association between risk factors and the occurrence of acute gastroenteritis over the entire outbreak duration. Environmental investigations and review of practices were carried out among staff. RESULTS Respectively 49/89 respondent residents (AR 58%) and 9/47 respondent staff members (AR 19%) reported gastrointestinal symptoms between September 17 and October 21, 2016. Norovirus type II was isolated in five stool samples. Residents with dependency score (Gir) below 4 were at higher risk of acute gastroenteritis [RR 2.1 (95% CI 1.1-4.1)] compared to those autonomous. It was the only identified risk factor. In addition, the review of practices in staff identified several breaks in the application of hygiene control standards including misuse of personal protective equipment (gloves were not changed between caring for different patients), inappropriate hand hygiene technique, and disinfection of environmental surfaces with an ineffective product on norovirus. CONCLUSIONS This episode reminds the importance of early recognition of acute gastroenteritis cases and the implementation of rigorous management measures in order to limit the spread of the epidemic in a highly vulnerable dependent population.

Abstract
OBJECTIVES Diarrheal diseases (DD) are an important cause of disease burden, especially in children in low-income settings. DD can also impact children's potential livelihood through growth faltering, cognitive impairment, and other sequelae. METHODS As part of the Global Burden of Disease study, we estimated DD burden, and the burden attributable to specific risk factors and etiologies, in the Eastern Mediterranean Region (EMR) between 1990 and 2015. We calculated disability-adjusted life-years (DALYs)-the sum of years of life lost and years lived with disability-for both sexes and all ages. RESULTS We estimate that over 103,692 diarrhea deaths occurred in the EMR in 2015 (95% uncertainty interval: 87,018-124,692), and the mortality rate was 16.0 deaths per 100,000 persons (95% UI: 13.4-19.2). The majority of these deaths occurred in children under 5 (63.3%) (65,670 deaths, 95% UI: 53,640-79,486). DALYs per 100,000 ranged from 304 (95% UI 228-400) in Kuwait to 38,900 (95% UI 25,900-54,300) in Somalia. CONCLUSIONS Our findings will guide evidence-based health policy decisions for interventions to achieve the ultimate goal of reducing the DD burden.

Abstract
Objectives The acute diarrhea is a common complaint among immunocompromised hosts, and may cause life threatening event. The infectious etiologies vary depending on virus, bacteria, and parasites. The most common etiology of acute gastroenteritis is known as enteric virus in Korea. But there are few studies about the infectious etiology of acute gastroenteritis in immunocompromised hosts. The aim of this study was to investigate the infectious etiologies of acute diarrhea in immunocompromised hosts. Methods Seventy three patients were enrolled prospectively in a university hospital from January 2013 to July 2014. Immunocompromised hosts included above 65-year-old people, patients with chronic diseases, solid organ or stem cell transplants, solid organ malignancies, hematologic malignancies, immunosuppressive or steroid taking patients. The clinical data were collected and stool samples collected during diarrhea were undergone laboratory analysis for enteric viruses and bacterial enteropathogens including Salmonella spp., Shigella spp., and Clostridium difficile. Results Fifty five patients were analyzed as follows : above 65 year-old people were 36 cases (66%), previous antibiotic usage was 22 cases (41.5%). 44 cases (81.1%) were admitted to general ward whereas 9 cases to ICU (17%). 41 cases (73.6%) were treated with antibiotics. Positive C. difficile toxin assays were 6 cases (11.9%). Other infectious etiologies were not found. Conclusions C. difficile infection was more common infectious etiology while enteric viruses and other bacteria are not associated with acute diarrhea among immunocompromised hosts in this study. So C. difficile infection must be considered preferentially in immunocompromised hosts with acute diarrhea.

Abstract
Diarrheal diseases (DD) are leading causes of disease burden, death, and disability, especially in children in low-income settings. DD can also impact a child's potential livelihood through stunted physical growth, cognitive impairment, and other sequelae. As part of the Global Burden of Disease Study, we estimated DD burden, and the burden attributable to specific risk factors and particular etiologies, in the Eastern Mediterranean Region (EMR) between 1990 and 2013. For both sexes and all ages, we calculated disability-adjusted life years (DALYs), which are the sum of years of life lost and years lived with disability. We estimate that over 125,000 deaths (3.6% of total deaths) were due to DD in the EMR in 2013, with a greater burden of DD in low- and middle-income countries. Diarrhea deaths per 100,000 children under 5 years of age ranged from one (95% uncertainty interval [UI] = 0-1) in Bahrain and Oman to 471 (95% UI = 245-763) in Somalia. The pattern for diarrhea DALYs among those under 5 years of age closely followed that for diarrheal deaths. DALYs per 100,000 ranged from 739 (95% UI = 520-989) in Syria to 40,869 (95% UI = 21,540-65,823) in Somalia. Our results highlighted a highly inequitable burden of DD in EMR, mainly driven by the lack of access to proper resources such as water and sanitation. Our findings will guide preventive and treatment interventions which are based on evidence and which follow the ultimate goal of reducing the DD burden.

[PMID: 25931997 PMCID: PMC4414754 DOI: 10.5217/ir.2015.13.2.128] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/19/2014] [Revised: 10/12/2014] [Accepted: 10/13/2014] [Indexed: 02/02/2023] Open
Abstract
BACKGROUND/AIMS As life expectancy has increased, the number of elderly patients who need long-term care has grown rapidly. Mortality in patients with colitis in long-term care facilities (LTCFs) is increasing. We intend to investigate the main causes of colitis in LTCFs compared to those of colitis in local communities, and to identify the clinical features and risk factors of patients with colitis in LTCFs. METHODS We retrospectively analyzed epidemiology, medical conditions, laboratory values, diagnoses, and clinical courses of elderly patients aged ≥65 who were admitted to the Ewha Womans University hospital with colitis between January 2007 and July 2012. RESULTS Patients with colitis in LTCFs (n=20) were compared with elderly patients with colitis in local communities (n=154). Fifty-five percent of colitis in LTCFs was caused by Clostridium difficile infection (CDI), 30% was due to ischemic colitis, and 15% was due to non-specific colitis. Non-specific colitis was the most common (63%) in the community group. Clinical outcomes were also significantly different between both groups: higher mortality (10.0% vs. 0.64%, P=0.021), higher requirement for intensive care units care (50.0% vs. 18.8%, P<0.01) in LTCFs group. In univariate analysis, the most significant risk factor for death in patients in LTCFs was decreased mental faculties. CONCLUSIONS Patients in LTCFs showed worse clinical outcomes and a much higher prevalence of CDI compared to patients from local communities. We suggest early and active evaluation, such as endoscopic examination, for differential diagnosis in patients in LTCFs.

Abstract
BACKGROUND In April 2013, an outbreak of acute gastroenteritis was reported in a residential long-term care facility (LTCF) in Ljubljana. We carried out an outbreak investigation to describe the outbreak, identify factors associated with contracting infection and to recommend control measures. METHODS We conducted descriptive epidemiology of the outbreak and a case-control study among residents; a case was a resident or staff member of the LTCF with acute diarrhoea and at least one of the following symptoms: fever, vomiting, nausea, fatigue, headache and abdominal pain between 11 and 23 April 2013. Controls had no gastrointestinal symptoms during the outbreak period. Stool specimens were tested for enteric pathogens, including Rotavirus. RESULTS Of 244, 33 (13.5 %) and 4 of 106 staff (3.8 %) were affected. Twenty-eight (84.8 %; median age 85 years; range 71-95 years) among affected residents and four (100 %; median age 35 years; range 30-45 years) among affected staff were women. The main symptoms besides acute diarrhoea were fatigue (54.1 %) and nausea (45.9 %). The average duration of gastroenteritis symptoms was 3.6 days in residents and 1.3 days in staff. None of the affected persons was hospitalized. Rotavirus group A was detected in a single stool specimen. In the multivariable analysis, being ambulant (aOR = 12.3; 95 % CI: 1.14-133.1), and having more than two comorbidities (aOR = 4.7; 95 % CI: 1.14-19.0) were significantly associated with acute gastroenterocolitis. CONCLUSIONS Contact precautions of affected persons and controlled staff interactions between outbreak ward and unaffected ward are recommended in times of outbreak, with additional effort in targeting mobile residents and those with comorbidities.

Abstract
BACKGROUND Understanding the potential links between extreme weather events and human health in India is important in the context of vulnerability and adaptation to climate change. Research exploring such linkages in India is sparse. OBJECTIVES We evaluated the association between extreme precipitation and gastrointestinal (GI) illness-related hospital admissions in Chennai, India, from 2004 to 2007. METHODS Daily hospital admissions were extracted from two government hospitals in Chennai, India, and meteorological data were retrieved from the Chennai International Airport. We evaluated the association between extreme precipitation (≥ 90th percentile) and hospital admissions using generalized additive models. Both single-day and distributed lag models were explored over a 15-day period, controlling for apparent temperature, day of week, and long-term time trends. We used a stratified analysis to explore the association across age and season. RESULTS Extreme precipitation was consistently associated with GI-related hospital admissions. The cumulative summary of risk ratios estimated for a 15-day period corresponding to an extreme event (relative to no precipitation) was 1.60 (95% CI: 1.29, 1.98) among all ages, 2.72 (95% CI: 1.25, 5.92) among the young (≤ 5 years of age), and 1.62 (95% CI: 0.97, 2.70) among the old (≥ 65 years of age). The association was stronger during the pre-monsoon season (March-May), with a cumulative risk ratio of 6.50 (95% CI: 2.22, 19.04) for all ages combined compared with other seasons. CONCLUSIONS Hospital admissions related to GI illness were positively associated with extreme precipitation in Chennai, India, with positive cumulative risk ratios for a 15-day period following an extreme event in all age groups. Projected changes in precipitation and extreme weather events suggest that climate change will have important implications for human health in India, where health disparities already exist.

Extreme precipitation and beach closures in the great lakes region: evaluating risk among the elderly. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2014; 11:2014-32.

Abstract
As a result of climate change, extreme precipitation events are expected to increase in frequency and intensity. Runoff from these extreme events poses threats to water quality and human health. We investigated the impact of extreme precipitation and beach closings on the risk of gastrointestinal illness (GI)-related hospital admissions among individuals 65 and older in 12 Great Lakes cities from 2000 to 2006. Poisson regression models were fit in each city, controlling for temperature and long-term time trends. City-specific estimates were combined to form an overall regional risk estimate. Approximately 40,000 GI-related hospital admissions and over 100 beach closure days were recorded from May through September during the study period. Extreme precipitation (≥90th percentile) occurring the previous day (lag 1) is significantly associated with beach closures in 8 of the 12 cities (p < 0.05). However, no association was observed between beach closures and GI-related hospital admissions. These results support previous work linking extreme precipitation to compromised recreational water quality.

Abstract
Background Infectious intestinal disease (IID) is a major health and economic burden in high-income countries. In the UK, there are an estimated 17 million IID cases annually, of which 6 million are caused by the 12 most common pathogens. Host factors that influence risk of IID are not well understood. Methods We analyzed data from the IID2 Study, a UK cohort that measured IID incidence, to investigate factors associated with recurrent IID. We calculated rates of IID by age group, sex, previous episodes experienced, and socioecomic indicators. We used Cox models to investigate factors associated with recurrent illness. Results The rate of IID was five times higher among infants than those aged 65 years and above (hazard ratio, HR = 5.0, 95% CI: 3.1 – 8.0). However, the association between previous IID and a subsequent IID episode was stronger in the elderly. Among those aged 65 years and above, each additional IID episode increased the rate of subsequent IID three-fold (HR = 3.1, 95% CI: 2.5 – 3.7). Among infants, the corresponding increase was 1.7-fold (HR = 1.7, 95% CI: 1.3 – 2.3). Conclusions Elderly populations have a high propensity for recurrent IID. More detailed studies are needed to identify vulnerable subgroups and susceptibility factors, and inform adequate control policies among the elderly.

Abstract
Pesquisou-se a prevalência de criptosporidiose em gatos domésticos de companhia em idosos de ambos os sexos (acima de 60 anos de idade) proprietários dos mesmos, residentes no município de Teresópolis-RJ, e que compareceram a um posto de vacinação do município no período da vacinação contra gripe de 2009 e 2010. A prevalência de diarreia nos idosos foi 29,4% e nos felinos 24,5%. Identificou-se presença de um ou mais oocistos em 16,7% dos idosos e em 12,7% nos felinos. A análise da razão de prevalência de diarreia evidenciou uma forte associação em idosos (RP = 4,37, IC a 95%: 2,67 - 7,16) e menor força de associação em felinos (RP = 2,16, IC a 95%: 1,06 - 4,39). Pela análise de imunofluorescência confirmada pela PCR, houve semelhante força de associação em idosos (RP = 4,43, IC a 95%: 3,04 - 6,45), mas se observou aumento na força de associação para felinos (RP = 4,67, IC a 95%: 3,9 - 6,81). Os achados obtidos com esta pesquisa são preocupantes, mas importantes para a saúde pública, por demonstrarem a relação zoonótica do Cryptosporidium spp. presente nas amostras fecais dos animais de companhia do grupo populacional de idosos estudados.

Abstract
Clostridium difficile is the main cause of nosocomial diarrhea. Diarrhea associated with C. difficile has increased incidence, morbidity, and mortality in the last few years. The major related risk factors include use of antibiotics, elderly patients and prolonged hospital stay. Many patients receive combinations of antibiotics or multiple antibiotics, which represents the main risk to develop diarrhea associated to C. difficile or its recurrence. Therefore, interventions to improve antibiotic prescribing, as well as compliance with infection control measures can reduce hospital-acquired C. difficile infections. This review addresses the epidemiological changes in C. difficile disease and its treatment.

Abstract
Symptoms are subjective patient experiences that may negatively impact the patient's hospitalization, treatment plan, and quality of life. Critically ill patients frequently experience nausea, vomiting, and diarrhea related to underlying disease, procedures, and medical interventions (eg, medication, enteral feeding, surgery). Optimally, the nurse performs a subjective assessment that explores the patient's perception and impact of these symptoms to develop a comprehensive plan of care. Unfortunately, little evidence is available to guide assessment of nausea, vomiting, and diarrhea in critically ill nonverbal patients. Understanding the disease processes, medical treatments, and pathophysiology of these symptoms will assist the critical care nurse in the anticipation of symptoms and development of a proactive plan to alleviate the symptom-associated discomfort.

Abstract
Transmission of foodborne pathogens remains a growing concern despite increasing public awareness and heightened federal measures to control infection. Over 76 million cases of acute diarrhea secondary to ingestion of contaminated food occur annually in the United States. Fortunately, most are self-limited and resolve without therapy, but up to 6000 deaths occur on an annual basis. Mechanisms of infection include consumption of a preformed toxin, formation of toxin following ingestion, and direct invasion of intestinal epithelial cells by the infecting organism. Diagnosis is most often confirmed through an accurate history, as cultures are often of low yield.

Abstract
Diseases that cause vomiting, diarrhea, constipation, and gastroenteritis are major problems for populations worldwide. Patients, particularly infants, elderly, and immunocompromised individuals, may present at any point in a wide spectrum of disease states, underscoring the need for the clinician to treat these ailments aggressively. Several promising new treatment modalities, from oral rehydration solutions to antiemetic therapies, have been introduced over the past decade. Future directions include the use of probiotic agents and better tolerated rehydration solutions. Gastrointestinal disease will continue to be a focus worldwide in the search for better ways to cure illnesses associated with vomiting and diarrhea.

Abstract
OBJETIVO: Este estudo visa a destacar a prevalência da criptosporidiose em animais de companhia doméstica. MÉTODO: Foram elegíveis para o estudo todos os idosos (acima de 60 anos de idade) de ambos os sexos que tenham cães e / ou gatos em casa, vivendo na cidade de Teresópolis e que foram a um posto de vacinação no município durante o período das campanhas nacionais de vacinação contra a gripe em 2007 e 2008. RESULTADOS: Em 29,0% dos animais pesquisados detectou-se a presença de oocistos e em 28,7% foram observados 2 ou mais oocistos por campo. A prevalência de história de diarreia entre os 300 animais examinados foi de 27%, atingindo 29,5% em cães e 24,7% em gatos, não mostrando diferença estatisticamente significativa entre as espécies. CONCLUSÃO: Este fato indica lacunas a serem mais aprofundadas, uma vez que são poucos estudos que exploram a relação da criptosporidiose com os animais de companhia na população humana. Os resultados demonstram a importância de realização periódica de exames parasitológicos em cães com e sem diarreia para tratamento específico e adoção medidas de controle e profilaxia.

Abstract
OBJECTIVE To determine the impact of probiotics on the prevention of problems with bowel movements malnutrition and infection. DESIGN A randomized, double-blind, placebo-controlled trial. SETTING Peripheral Geriatric Hospital. PARTICIPANTS 243 elderly patients age ≥ 65 y who were hospitalized in a Geriatric Orthopedic Rehabilitation Department. INTERVENTION Participants were randomized into treatment or control groups (daily probiotics or placebo for 45 consecutive days, respectively). MEASUREMENTS The main outcomes were: number of days of constipation or diarrhea and the number of days of laxative use. Secondary measures were nutritional status and blood measurements. RESULTS Of 599 patients admitted to the Geriatric Rehabilitation ward, 345 were eligible and agreed to participate. During a 7-day pre-trial period, 102 patients dropped out (45 and 57 in the probiotic and placebo groups respectively). Out of the 243 patients who entered the study, 28 dropped out during the study (11.5%), leaving 215 patients. Throughout the 45 days of follow-up, the incidence of diarrhea was significantly lower among the study group (HR=0.42, p=0.04) with a more pronounced difference among participants aged ≥ 80 y (HR=0.32, p=0.026). Laxative use (as an indicator of constipation severity) was significantly lower in the study group compared with the control group (HR=0.74, p=0.032). Serum albumin, prealbumin and protein increased significantly more in the treatment group compared with the control group among participants age ≥ 80 y (P=0.047, p=0.07, p=0.03 respectively) but not in the younger age group. CONCLUSION We showed that probiotic supplements may have a positive effect on bowel movements among orthopedic rehabilitation elderly patients.

Abstract
Diarrhoeal diseases are common in older populations and often markedly affect their quality of life. Although there are numerous potential causes, microscopic colitis (MC) is increasingly recognised as a major diagnostic entity in older individuals. MC is comprised of two distinct histological forms - collagenous colitis and lymphocytic colitis, both of which frequently occur in older populations. Recent studies suggest that between 10 and 30% of older patients investigated for chronic diarrhoea with an endoscopically normal appearing colon will have MC. It is unclear why MC is more common in older populations, but it is associated with both autoimmune disorders and several drugs that are commonly used by seniors. A definitive diagnosis can only be made with colonic biopsies. Since MC was first described in 1976 and only recently recognised as a common cause of diarrhoea, many practising physicians may not be aware of this entity. In this review, we outline the epidemiology, risk factors associated with MC, its pathophysiology, the approach to diagnosis and the management of these individuals.

Abstract
Recent progress in understanding visceral afferents, some of it reviewed in the present issue, serves to underscore how little is known about the aging of the visceral afferents in the gastrointestinal (GI) tract. In spite of the clinical importance of the issue-with age, GI function often becomes severely compromised-only a few initial observations on age-related structural changes of visceral afferents are available. Primary afferent cell bodies in both the nodose ganglia and dorsal root ganglia lose Nissl material and accumulate lipofucsin, inclusions, aggregates, and tangles. Additionally, in changes that we focus on in the present review, vagal visceral afferent terminals in both the muscle wall and the mucosa of the GI tract exhibit age-related structural changes. In aged animals, both of the vagal terminal types examined, namely intraganglionic laminar endings and villus afferents, exhibit dystrophic or regressive morphological changes. These neuropathies are associated with age-related changes in the structural integrity of the target organs of the affected afferents, suggesting that local changes in trophic environment may give rise to the aging of GI innervation. Given the clinical relevance of GI tract aging, a more complete understanding both of how aging alters the innervation of the gut and of how such changes might be mitigated should be made research priorities.

Abstract
Dystrophic axons and terminals are common in the myenteric plexus and smooth muscle of the gastrointestinal (GI) tract of aged rats. In young adult rats, alpha-synuclein in its normal state is abundant throughout the myenteric plexus, making this protein-which is prone to fibrillization-a candidate marker for axonopathies in the aged rat. To determine if aggregation of alpha-synuclein is involved in the formation of age-related enteric neuropathies, we sampled the stomach, small intestine and large intestine of adult, middle-aged, and aged virgin male Fischer 344 rats stained for alpha-synuclein in both its normal and pathological states. Alpha-synuclein-positive dystrophic axons and terminals were present throughout the GI tract of middle-aged and aged rats, with immunohistochemical double labeling demonstrating co-localization within nitric oxide synthase-, calretinin-, calbindin-, or tyrosine hydroxylase-positive markedly swollen neurites. However, other dystrophic neurites positive for each of these four markers were not co-reactive for alpha-synuclein. Similarly, a subpopulation of alpha-synuclein inclusions contained deposits immunostained with an anti-tau phospho-specific Ser(262) antibody, but not all of these hyperphosphorylated tau-positive aggregates were co-localized with alpha-synuclein. The presence of heteroplastic and potentially degenerating neural elements and protein aggregates both positive and negative for alpha-synuclein suggests a complex chronological relationship between the onset of degenerative changes and the accumulation of misfolded proteins. Additionally, proteins other than alpha-synuclein appear to be involved in age-related axonopathies. Finally, this study establishes the utility of the aging Fischer 344 rat for the study of synucleopathies and tauopathies in the GI tract.

A novel bocavirus associated with acute gastroenteritis in Australian children. PLoS Pathog 2009; 5:e1000391.

Abstract
Acute gastroenteritis (AGE) is a common illness affecting all age groups worldwide, causing an estimated three million deaths annually. Viruses such as rotavirus, adenovirus, and caliciviruses are a major cause of AGE, but in many patients a causal agent cannot be found despite extensive diagnostic testing. Proposing that novel viruses are the reason for this diagnostic gap, we used molecular screening to investigate a cluster of undiagnosed cases that were part of a larger case control study into the etiology of pediatric AGE. Degenerate oligonucleotide primed (DOP) PCR was used to non-specifically amplify viral DNA from fecal specimens. The amplified DNA was then cloned and sequenced for analysis. A novel virus was detected. Elucidation and analysis of the genome indicates it is a member of the Bocavirus genus of the Parvovirinae, 23% variant at the nucleotide level from its closest formally recognized relative, the Human Bocavirus (HBoV), and similar to the very recently proposed second species of Bocavirus (HBoV2). Fecal samples collected from case control pairs during 2001 for the AGE study were tested with a bocavirus-specific PCR, and HBoV2 (sequence confirmed) was detected in 32 of 186 cases with AGE (prevalence 17.2%) compared with only 15 controls (8.1%). In this same group of children, HBoV2 prevalence was exceeded only by rotavirus (39.2%) and astrovirus (21.5%) and was more prevalent than norovirus genogroup 2 (13.4%) and adenovirus (4.8%). In a univariate analysis of the matched pairs (McNemar's Test), the odds ratio for the association of AGE with HBoV2 infection was 2.6 (95% confidence interval 1.2–5.7); P = 0.007. During the course of this screening, a second novel bocavirus was detected which we have designated HBoV species 3 (HBoV3). The prevalence of HBoV3 was low (2.7%), and it was not associated with AGE. HBoV2 and HBoV3 are newly discovered bocaviruses, of which HBoV2 is the thirdmost-prevalent virus, after rotavirus and astrovirus, associated with pediatric AGE in this study. Acute gastroenteritis (AGE) is a common illness affecting all age groups worldwide, causing an estimated three million deaths annually. However, in many patients a causal agent cannot be found despite extensive diagnostic testing. Proposing that novel viruses are the reason for this diagnostic gap, we screened fecal samples from symptomatic children using a molecular degenerate amplification technique and detected the presence of a novel parvovirus, Human Bocavirus species 2 (HBoV2). The genome of HBoV2 is 23% variant from its closest relative, the human bocavirus, a member of the Bocavirus genus of the Parvovirinae. Using specific amplification assays, we then found HBoV2 was the thirdmost-prevalent virus detected in samples from symptomatic children in a case control study of AGE. Further, we found virus presence was associated with symptoms. During this screening, we detected a second related parvovirus, which we have named Human Bocavirus species 3 (HBoV3), but the prevalence was low and not associated with symptoms. The discovery of HBoV2 has reduced the diagnostic gap, but more studies are required to further investigate its role in AGE.

Abstract
Many people with long term conditions wish to receive care at home or in the nursing home where they live. Sometimes if a person develops diarrhoea the clinician's first instinct is to transfer the person to hospital. The person who has severe diarrhoea may need hospitalisation, however many people, especially those who have indicated that their preferred place of care is home rather than hospital, can be managed effectively at home. Enabling the person to remain at home whenever possible empowers the person and enables carers, community nursing staff and nursing home staff to provide the best possible level of care.
