RESUMO
PURPOSE: This review was conducted to systematically assess the impact of bisphosphonates (BPs) and denosumab, used as anti-resorptive therapies, on the incidence of dental implant failure. METHODS: Electronic and manual searches were performed in accordance with the described search protocol. Only articles that met the inclusion criteria were selected. The primary outcome was implant failure, while secondary outcomes included biological complications and comorbidities. Following data extraction, a quality assessment and meta-analysis were conducted. RESULTS: Fourteen eligible studies were included in the analysis following a qualitative evaluation. BP administration, regardless of the timing of anti-resorptive therapy, did not significantly increase the risk of implant failure (odds ratio [OR], 1.40; 95% confidence interval, 0.83-2.34). Subgroup analysis revealed a slightly higher, although statistically insignificant, risk of failure in patients with a follow-up period of 3 years or more compared to those with a follow-up duration of less than 3 years (with ORs of 2.82 and 1.53, respectively). Due to a lack of eligible studies, a meta-analysis for denosumab could not be conducted. CONCLUSIONS: Our findings suggest that BP treatment does not compromise the survival of dental implants. Specifically, in patients with osteoporosis, implant failure rates were not significantly influenced by the administration of BPs before the placement of dental implants, suggesting that low-dose BP therapy may not contraindicate implant placement. Nevertheless, regular check-ups and maintenance periodontal treatment must not be neglected, and concomitant biological factors should be considered to ensure the long-term success of implant rehabilitation.
RESUMO
BACKGROUND: Musculoskeletal disability (MSD) has been identified as having a negative impact on oral health. Patients with MSD have a greater burden of medical expenses and are expected to have an Economic unmet dental need (UDN). This study aimed to conduct a multifactorial analysis based on the Andersen model to determine the extent to which MSD contributes to inequitable dental care use. METHODS: This study used data from the Korea National Health and Nutrition Survey VIII. The study population was 17,903 adults aged 19 years and older. All data were analyzed using IBM SPSS Statistics for Windows version 26 and the level of statistical significance was set at 0.05. RESULTS: The people with MSD activity limitations were rare as only 3% in this study population. There were significant differences in sex and education as predisposing factors, income, and marital status as enabling factors, and current smoking, daily brushing, and MSD activity limitation as need factors for experiencing economic UDN. MSD activity limitation was associated with 1.5-fold increased odds of Economic UDN with a fully adjusted Anderson's Behavior Model. CONCLUSIONS: This finding suggests poorer access to dental care among adults with MSDs owing to financial difficulties. It is necessary to explore various ways to address oral health inequalities among adults with MSD activity limitations.

OBJECTIVES: This study aims to evaluate the potential benefits of combining tongue reduction with mandibular setback surgery in patients undergoing class III orthognathic surgery. Specifically, we investigated whether this combined approach reduced the risk of surgical relapse, condylar resorption, and airway space reduction by mitigating tongue pressure on the mandible. MATERIAL AND METHODS: The study retrospectively enrolled patients who had undergone bilateral sagittal split ramus osteotomy (BSSRO) with at least 5 mm of setback and met the criteria of a body mass index > 20 kg/m2 and tongue volume > 100 mm3. The study included 20 patients with 10 in the tongue reduction group (TR, n = 10) and 10 in the BSSRO only group (SO, n = 10). RESULTS: The volumetric changes of the total airway space were significantly different between the TR and SO groups (p = 0.028). However, no significant differences were observed in the condylar resorption and postoperative relapse between the groups (p = 0.927 and 0.913, respectively). The difference between the resorption of the anterior and posterior segments of the condyle was also statistically insignificant (p = 0.826). Postoperative counterclockwise rotation of the proximal segment only demonstrated a significant correlation with postoperative relapse (p = 0.048). CONCLUSIONS: The reduction in tongue volume demonstrated a preventive effect on the reduction of the airway space after mandibular setback, although it did not yield statistical significance concerning surgical relapse and condylar volume. The counterclockwise rotation of the proximal segment might be responsible for the forward displacement of the distal segment and postoperative relapse. However, the clinical implications of this finding should be interpreted with caution owing to the limited sample size CLINICAL RELEVANCE: Tongue reduction could potentially serve as a preventive measure in preserving the airway space and might be beneficial in mitigating the risk of obstructive sleep apnea in patients with class III deformity.

BACKGROUND: Health status and health care utilization in people with disabilities are more likely to be poorer than those without disabilities. Previous studies showed that there were gaps in health-related conditions by sociodemographic information and gender but the association between these factors was not explained. This study aims to analyze the relationship between sociodemographic information and the unmet dental care needs of people with disabilities and explore the effect of sex within this relationship. METHODS: The 2014 national survey on persons with disabilities was used, which separated unmet healthcare needs into medical and dental services. Unweighted samples included 6,824 people with disabilities in total and 6,555 (96.1% of the total, weighted as 6,583) people aged 20 years or older were selected as the study population. Frequency and chi-square tests were conducted to determine differences in the prevalence of unmet dental needs based on socioeconomic information, chronic diseases, and behavioral factors after applying weights. Logistic regressions were performed using an adjusted model with sociodemographic information, chronic diseases, and behavioral variables. All analyses were performed using IBM SPSS Statistics for Windows, version 26 (IBM Corp., Armonk, N.Y., USA). RESULTS: Analysis of the sociodemographic factors related to unmet dental care revealed that they were higher in women and the elderly. In the fully adjusted logistic model, most of the sociodemographic information was significantly associated with unmet dental needs. The lowest group was 4.18 times more likely to have unmet dental care needs than the richest group, and females and middle-school graduates were almost twice as likely to experience unmet dental care needs than males and university graduates. Considering the interaction effect of age on unmet dental needs depending on sex differences, the odds ratio decreased for females with every annual increase in both models. Compared with the younger group, the older group showed a lower risk of having unmet dental needs, especially in females. CONCLUSIONS: The factor most closely related to the unmet dental care needs of disabled people was socioeconomic problems. Its influence also differed by sex and age. Therefore, economic support measures and sexual differences are needed for long-term policy consideration to reduce the unmet dental care needs of disabled people.

BACKGROUND: Prevention and treatment services use is closely associated with socioeconomic factors, such as income. This study aimed to investigate the relationship between implementing the sealant program and resin fillings restoration and to explore the role of income and frequency of dental visits in this relationship. METHODS: This retrospective cohort study used the cohort database from the National Health Information Database of the National Health Insurance Service. The study population comprised 494,731 children born in 2007. A logistic regression model for the experience of resin fillings and a linear regression model for weighted utilization of them were used to identify the independent effects of dental sealants, income, and frequency of dental visits. All analyses were conducted using the SAS Enterprise Guide version 7.1 (SAS Institute Inc., Cary, NC, USA). RESULTS: The ratio based on income level was almost proportional in all groups except the medical aid group, which had a rate as high as that of the wealthier group. Children without sealants were 1.05 times more likely to have resin fillings than others after adjusting for income level and frequency of visiting dental clinics in the final model. However, an opposite relationship between sealant experiences and resin fillings was observed in the previous model without dental visits. The gap in the weighted resin filling scores according to socioeconomic variables showed a similar tendency. CONCLUSIONS: Income and frequency of dental visits might be confounding factors for the relationship between dental sealant and resin fillings. It is necessary to consider the complex relationship between socioeconomic indicators and service use while studying oral health inequality.

OBJECTIVES: To review the current evidence on the relationship between agents that affect bone homeostasis and dental implant failures. MATERIALS AND METHODS: Electronic searches for bisphosphonates, denosumab, methotrexate, corticosteroids, romosozumab, sunitinib, and bevacizumab were performed using PubMed, MEDLINE (OVID), EMBASE (OVID), Cochrane Central Register of Controlled Trials (Cochrane Library), Cochrane Oral Health Group Trials Register (Cochrane Library) and Web of Science (Thomson Reuters). Manual searches were also conducted to complement the digital searches for recent issues. RESULTS: Previous publications suggested that bisphosphonates do not compromise the survival of dental implants. However, one study documented an increased risk of implant failure in patients who had received high-dose of intravenous bisphosphonate therapy after implant rehabilitation. There has been an issue of MRONJ around implants in patients who have successfully received implant therapy before and after antiresorptive therapy, leading to late implant failure. Despite evidence on the detrimental effects of denosumab, methotrexate and corticosteroids on bone metabolism, their role in implant survival is not conclusive. CONCLUSIONS: At present, there is insufficient evidence to establish a potential connection between agents that affects bone homeostasis and implant failure. However, some studies have reported negative results for implant therapy. In addition, implant-related sequestration in patients who received anti-resorptive therapy, despite of successful osseointegration, is also noticeable. Although limited studies are available at present, clinicians should still carefully consider the potential hazards and take appropriate precautions to minimize the risks associated with the medications and implant therapy.

The proportion aged 60 years or older in the world's population is expected to double by 2050. In general, they have many complex diseases and poor oral health status. Oral health is one of the important health indicators of elderly people and it is affected by diverse factors, such as socioeconomic status. In this study, sexual difference was considered as an associated factor that is closely related to edentulism. The sexual difference might be more influential within the geriatric population because of lower economic and educational backgrounds at this stage. Edentulism was significantly higher among elderly females than males when combined with the education level. The lower the level of education, the higher the prevalence of edentulism as much as 24 ~ 28 times, especially in females (P = 0.002). These findings suggest a more complex relationship between oral health, socioeconomic status, and sexual difference.

BACKGROUND/OBJECTIVES: Fucoidan has been focused as a multifunctional therapeutic uses including bone health supplements. However, the critical molecular mechanisms of fucoidan for bone therapeutic agents have not been fully understood. We investigated the osteoinductive effect of fucoidan on periodontal ligament stem cells (PDLSCs) and how this polymer encouraged PDLSC osteogenesis. MATERIALS AND METHODS: Osteogenic induction of PDLSCs was processed by culturing cells with fucoidan treatment. Osteogenic differentiation of PDLSCs was verified by alkaline phosphatase (ALP) activity, matrix mineralization assay, intracellular calcium levels, and mRNA expression and protein levels of osteogenic markers. RESULTS: Fucoidan treatment showed higher osteogenic activity in the PDLSCs than the control groups. PDLSCs with fucoidan also presented increased levels of the phosphatidylinositol-3-kinase (PI3K) isoforms, p110α and p110γ compared to control cells. The phosphorylation of Akt, a PI3K downstream effector, was significantly increased at 90 min of fucoidan induction. Expression of ß-catenin, a coactivator of canonical Wnt pathways, was increased in PDLSCs with fucoidan. ß-catenin was found to link with PI3K activation during the fucoidan stimulation. When cells were blocked by PI3K inhibitor or ß-catenin-specific siRNA, fucoidan-induced osteogenic activity of PDLSCs was significantly attenuated. CONCLUSION: These findings suggest that the fucoidan stimulates osteogenic differentiation of PDLSCs via the PI3K/Akt and Wnt/ß-catenin pathways.

Dental disease is one of the most prevalent chronic diseases worldwide, and its expenditure is continuously increasing. Periodontal disease is increasing as a chronic non-communicable disease in adults and older people. Health screening has been shown to be cost-effective and improves the quality of life through the early detection of diseases. This study aimed to analyze the relationship between national health screening and dental scaling as a preventive service for periodontal disease. The study used sample cohort data from 2002 to 2015 provided by the National Health Insurance Sharing Service in South Korea. A logistic regression analysis of the utilization of dental scaling was performed to identify the independent effects of national health screening. People who underwent health screening showed a higher tendency to undergo dental scaling. Additionally, disparities in utilization according to socioeconomic status were reduced among those who underwent screening. The intervention to extend dental coverage could be more beneficial when combined with health screening, encouraging more people to participate and reducing inequalities in utilization.

OBJECTIVES: This study aimed to investigate the association between dental implant therapy and osteonecrosis of the jaw (ONJ) in osteoporotic patients and the relationship between tooth extraction, dental implantation, and ONJ. MATERIAL AND METHODS: This retrospective cohort study used the Customized Health Information Data from the National Health Insurance Corporation in South Korea. The study population included patients older than 70 years with a history of osteoporosis; the cases included patients who had undergone dental implant surgery between July 2014 and July 2016 with specific procedure codes. The case and control cohorts were stratified by tooth extraction because it was the strongest risk factor to consider in this study. Each group of patients was matched using the propensity score. To investigate the relationship between dental implants and ONJ, a Cox proportional hazard model was applied to socio-economic factors, comorbidities, and bisphosphonates (BPs). All analyses were conducted using SAS statistical software. RESULTS: Based on the fully adjusted model, the propensity score-matched osteoporosis patients with dental implants had a 0.51 times hazard ratio of osteonecrosis. On the contrary, tooth extraction was associated with a higher risk of ONJ (HR = 5.89). The patients with rheumatoid arthritis (RA) and those using BPs had a higher HR, respectively, 6.80 and 4.09 HR (p < .001). CONCLUSIONS: Dental implantation was not a risk factor and patients with implants show rather lower ratios. However, older osteoporotic Korean patients who had undergone tooth extraction had higher risks of ONJ. A significantly higher risk of ONJ was associated with RA and BPs as well.

Many countries provide preventive dental care for children to reduce inequalities. In Korea, the registered dentists' program was implemented to promote oral health and prevent oral diseases in primary school students. This study aimed to evaluate the registered dentist program through the sealant utilization rate using national cohort data and to compare the socioeconomic gap of the cohorts by participation. The sample cohort data were obtained from the National Health Insurance Sharing Service (NHISS) in South Korea. The utilization of dental sealants was analyzed using the chi-square test according to the independent variables of each year. To identify the independent effects of participation in the registered dentists' program, a panel logistic regression analysis of the utilization of dental sealants was performed. The participants were 1.35 times more likely to have dental sealants than non-participants. The significance of income quintiles disappeared in the case groups. The gap became more obvious in the employees of the control group even after adjusting for all variables. Implementing oral health programs can alleviate inequality with a relative increase in utilization in vulnerable populations.

(1) Background: Homelessness contributes to both needs for care and barriers to access. This study aimed to explore the utilization of medical or dental services using Andersen's model for a vulnerable population of homeless in South Korea. (2) Methods: The data were applied from the first national survey for homeless people in South Korea, 2016. Totally 2032 persons participated in the interview survey. This study team requested the raw data through the public portal and analyzed them. (3) Results: The participants who were homeless for more than ten years, staying in small rooming house or shelter, non-employed, earning less than 500,000 won per month, and having a medical condition showed a significantly higher chance of using Medicaid. The use of outreach programs had a significant relationship with gender, duration of homelessness, and monthly income. Among dental patients, the homeless who did not consume alcohol, stayed in a shelter, and were employed had higher chances of using dental service. (4) Conclusions: Medicaid service was strongly related to enabling factors but outreach programs with predisposing factors. Dental service showed strong relationships with the enabling domain, but the pattern was opposite: the jobless had less chance to avail it. The policymakers need to consider these domains of service utilization to provide equitable access to healthcare services.

BACKGROUND: Dental sealants have been covered by the National Health Insurance Service (NHIS) since December 2009 in South Korea. This study aims to determine whether the socioeconomic inequality in untreated dental caries decreased after implementing the extended coverage policy for dental sealant. METHODS: The data were derived from the fourth (2007-2009) and sixth (2013-2015) waves of the Korean National Health and Nutrition Examination Survey (KNHANES) conducted by the Korea Centers for Disease Control and Prevention (KCDC). Dental caries and sealant experience by income quartiles were tested using the Rao-Scott chi-squared test. In order to examine socioeconomic inequalities and their trends over time, the prevalence ratios (PRs), slope index of inequality (SII), and relative index of inequality (RII) were estimated for each wave and age group. All analyses were conducted using SAS version 9.3. RESULTS: The adjusted PRs of untreated dental caries and sealants in the poorest in the aged 6-11 group were significantly higher and lower, respectively, compared to the most affluent quartile group for the fourth wave; however, all significant differences disappeared for the sixth wave, after the sealant coverage. The gap between the lowest and the highest was similar for the aged 12-18 group but it widened in the untreated dental caries even after the sealant coverage. The statistical significance of the PRs was maintained at the sixth wave for both caries and sealants. Children showed decreases in both SII and RII over time so its significance disappeared. The SII among adolescents decreased over time but the RII of untreated dental caries increased. CONCLUSIONS: This study found that the NHIS coverage expansion of dental care had a positive effect on overall status in dental health among children and adolescents. However, younger children benefited more in terms of inequalities. Our findings indicate that strategies to enhance access to preventive dental services should consider the differential effects for the vulnerable population in terms of socioeconomic status and age from the beginning stage of the policy.

Porphyromonas species are closely associated with companion animal periodontitis which is one of the most common diseases in dogs and cats and leads to serious systemic diseases if left untreated. In this study, we evaluated the antimicrobial effects and mode of action of sodium tripolyphosphate (polyP3, Na5P3O10), a food additive with proven safety, using three pathogenic Porphyromonas species. The minimum inhibitory concentrations (MICs) of polyP3 against Porphyromonas gulae, Porphyromonas cansulci, and Porphyromonas cangingivalis were between 500 and 750 mg/L. PolyP3 significantly decreased viable planktonic cells as well as bacterial biofilm formation, even at sub-MIC concentrations. PolyP3 caused bacterial membrane disruption and this effect was most prominent in P. cangingivalis, which was demonstrated by measuring the amount of nucleotide leakage from the cells. To further investigate the mode of action of polyP3, high-throughput whole-transcriptome sequencing was performed using P. gulae. Approximately 30% of the total genes of P. gulae were differentially expressed by polyP3 (> 4-fold, adjusted p value < 0.01). PolyP3 influenced the expression of the P. gulae genes related to the biosynthesis of thiamine, ubiquinone, and peptidoglycan. Collectively, polyP3 has excellent antibacterial effects against pathogenic Porphyromonas species and can be a promising agent to control oral pathogenic bacteria in companion animals.

Polyphosphate (polyP) is a food additive with antimicrobial activity. Here we evaluated the effects of sodium tripolyphosphate (polyP3, Na5P3O10) on four major oral bacterial species, in both single- and mixed-culture. PolyP3 inhibited three opportunistic pathogenic species: Fusobacterium nucleatum, Prevotella intermedia, and Porphyromonas gingivalis. On the contrary, a commensal bacterium Streptococcus gordonii was relatively less susceptible to polyP3 than the pathogens. When all bacterial species were co-cultured, polyP3 (≥ 0.09%) significantly reduced their total growth and biofilm formation, among which the three pathogenic bacteria were selectively inhibited. Collectively, polyP3 may be an alternative antibacterial agent to control oral pathogenic bacteria.Polyphosphate (polyP) is a food additive with antimicrobial activity.

INTRODUCTION: This study aimed to evaluate the associations between normative orthodontic treatment need and oral health-related quality of life (OHRQoL) at an item level as well as subscale and total score levels among schoolchildren. METHODS: A cross-sectional study was conducted on 2,010 randomly selected children aged approximately 8, 10, 12, and 15 years residing in the Gyeonggi province, Korea. Children were clinically examined with the Index of Orthodontic Treatment Need (IOTN). To measure OHRQoL, the Child Oral Health Impact Profile (COHIP) was used. RESULTS: In the physical health domain of COHIP, crooked teeth, discoloration, "food sticking," and "difficulty keeping teeth clean" were significantly associated with IOTN levels (P < 0.05), whereas pain, sensitivity and bleeding, bad breath, mouth breathing, and dry mouth were not. In addition, present and future dental health were significantly associated with IOTN levels, although self-confidence, attractiveness, and future health were not. As expected, the 5 subscale scores and total score of COHIP were significantly associated with IOTN levels after adjustment for gender, age, socioeconomic level, and caries state. CONCLUSIONS: This study suggests the importance of in-depth investigation at the item level of OHRQoL assessment scales to better evaluate the impact of malocclusion that might be alleviated by orthodontic treatment.

AIM: The aims of this study were to examine inequalities in periodontitis and tooth loss among South Korean adults using the Wright's Neo-Marxian social class (NMSC) indicator and to assess the impact of material, psychosocial, health behavioural and workplace environmental factors in the association of social class with oral health. METHODS: This study used the data from the 4th Korea National Health and Nutrition Examination Survey with 6710 participants aged 19-54 years old. Participants were classified into 12 social class positions based on the Wright's social class map. Healthy gum and absence of tooth loss were the health outcomes. Mediating factors were material (M), psychosocial (PS), health behavioural (HB) and workplace environmental (WPE) factors. A series of logistic regressions were performed to analyse the data. Odds ratio (OR) and 95% confidence interval (CI) were used to report the results. RESULTS: For the absence of periodontal pockets status, expert supervisors were the healthiest periodontal group among the social classes (OR = 2.15 95% CI 1.59-2.90) in the age and gender adjusted model. For the absence of tooth loss, skilled workers had the highest OR for absence of tooth loss (OR = 1.64 95% CI 1.31-2.05) in the age- and gender-adjusted model. For absence of periodontal pockets, the explanatory power of the M factor was the highest in all social class positions except for nonskilled supervisors followed by the HB factor. Additionally, the absence of tooth loss had a fairly similar pattern. The explanatory power of the M factor was the highest in all social class positions except for the petty bourgeoisie (highest: HB) and nonskilled supervisors (highest: WPE) followed by the HB and WPE factors. CONCLUSION: There were nongradient oral health inequalities among the South Korean population according to the NMSC. Oral health promotion programmes that focus on changing the socioeconomic environment and health behaviours should be implemented.

BACKGROUND: This study aims to evaluate inequality in oral health among adolescents and to explain the mechanisms of such inequalities in Gangneung, South Korea. METHODS: One thousand two hundred sixty-seven students in their first year from four vocational and three general schools participated in the baseline survey of 2011, and 84.7% of them were surveyed again in 2013. Oral examinations by the same dentist and a self-administered questionnaire were repeated during both waves. Outcome measure for oral health was the existence of untreated dental caries (DT). As socioeconomic position (SEP) indicators, school type (general vs. vocational), father's and mother's education, perceived economic status, and Family Affluence Scale (FAS) were measured. Variables measuring oral health related behaviours included tooth brushing frequency, frequency of eating snacks and drinking sodas, smoking, and annual visits to dental clinics. Chi-square tests and panel logistic regression were adopted to examine the associations between dental caries and SEP indicators by STATA version 15.1. RESULTS: Having a less educated father and attending a vocational school were significant predictors for untreated caries after controlling for SEP indicators. However, students from general schools, higher SEP by father's education, perceived economic status, or FAS, or having non-smoking experience or annual visits to dental clinics were more likely to stay caries-free. CONCLUSIONS: There were socioeconomic inequalities in oral health on an adolescent panel. Given that oral health status during adolescents can persist throughout the course of a person's life, intervention to tackle such inequalities and school environments are required.

BACKGROUND/AIMS: Bloating is common bothersome symptoms and most studies conducted in the Western countries found that bloating was frequently associated with lower gastrointestinal (GI) symptoms but many patients complaint bloating as upper GI symptoms in the clinical setting. This study was conducted to assess the prevalence of bloating, and to identify symptom grouping and finally document the impact of bloating in the diagnosis of functional GI disorders. METHODS: Participants in a comprehensive health-screening cohort were enrolled. They were asked about demographic, medical, and social history and upper and lower GI symptoms by using a validated questionnaire. Factor analysis with principal component analysis method with varimax rotation was used. RESULTS: Among the total of 1050 subjects (mean age, 44.6 ± 10.2 years; females, 46.4%), significant bloating symptoms were found in 282 (26.9%); the prevalence of functional bloating was 6.9%. Factor analysis revealed a 5-component structure with upper GI symptoms, constipation, diarrhea-predominant irritable bowel syndrome (IBS), constipation-predominant IBS, and fecal incontinence. Abdominal bloating loaded on both the upper GI symptoms (0.51 of loadings) and constipation (0.40). On logistic regression analysis, bloating was more predictable for IBS (OR, 7.5; P < 0.001) than functional dyspepsia (FD; OR, 3.7; P = 0.002). Bloating was more frequently combined with IBS according to their severity, but this association was not detected in patients with FD. CONCLUSIONS: Abdominal bloating is common symptom in about a quarter of patients and appears as upper as well as lower GI symptoms. However, abdominal bloating is more predictable for IBS, especially constipation-predominant IBS, than FD.
RESUMO
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.
