RESUMEN
BACKGROUND/OBJECTIVES: Chronic pancreatitis (CP) is a progressive inflammatory disorder associated with marked morbidity and mortality and frequently requires hospitalization. This study aimed to investigate the time trends and geographical distribution of hospital admissions, the lethality rate of CP across Brazil, and the potential relationship with social indicators and associated risk factors. METHODS: Data were retrospectively obtained from the Brazilian Public Health System Registry between January 2009 and December 2019. The prevalence and lethality rates of CP per 100,000 inhabitants in each municipality were estimated from hospitalizations to in-hospital deaths and classified by age, sex, and demographic features. RESULTS: During the study period, 64,609 admissions were retrieved, and most of the patients were males (63.54%). Hospitalization decreased by nearly half (-54.68%) in both sexes. CP rates in males were higher in all age groups. The greatest reduction in admissions (- 64%) was also noted in patients ≥ 70y. CP In-hospital lethality remained stable (5-6%) and similar for males and females. Patients ≥ 70y showed the highest lethality. The greatest increase in CP lethality rates (+ 10%) was observed in municipalities integrated into metropolises, which was mainly driven by small-sized municipalities (+ 124%). CONCLUSIONS: CP hospitalizations decrease in both urban and rural areas, particularly in the North, Northeast, and Central-West regions, and in those above 70 years of age, but are not correlated with lethality rates in the South. This suggests ongoing changes in the environmental and socioeconomic factors in Brazil.

BACKGROUND: Colorectal cancer (CRC) is the third most common malignancy and the second leading cause of cancer-related death in the world. The aim of this study was to investigate the geographic distribution and time trends of CRC in Brazil. METHODS: Data were retrospectively retrieved from January 2005 to December 2018 from the Brazilian Public Health System. The incidence and lethality rates of CRC per 100,000 inhabitants in each municipality were estimated from hospitalizations and in-hospital deaths and were classified by age, sex, and demographic features. RESULTS: During the study period, the mean incidence of CRC estimated from hospitalizations and adjusted to available hospital beds more than tripled from 14.6 to 51.4 per 100,000 inhabitants (352%). Increases in CRC incidence were detected in all age ranges, particularly among people aged 50-69 years (266%). Incidence rates increased in all 5 macroregions, with a clear South to North gradient. The greatest changes in incidence and lethality rates were registered in small-sized municipalities. CRC lethality estimated from in-hospital deaths decreased similarly in both sexes, from 12 to 8% for males and females, from 2005 to 2018. The decline in lethality rates was seen in all age ranges, mainly in people aged 50 to 69 years (- 38%). CONCLUSIONS: CRC incidence is increasing, predominantly above fifty years of age, and also in areas previously considered as having low incidence, but the increase is not paralleled by lethality rates. This suggests recent improvements in CRC screening programs and treatment, but also supports the spread of environmental risk factors throughout the country.

BACKGROUND: The epidemiology of inflammatory bowel disease (IBD) in developing countries may uncover etiopathogenic factors. We investigated IBD prevalence in Brazil by investigating its geographic, spatial, and temporal distribution, and attempted to identify factors associated with its recent increase. METHODS: A drug prescription database was queried longitudinally to identify patients and verify population distribution and density, race, urbanicity, sanitation, and Human Development Index. Prevalence was calculated using the number of IBD patients and the population estimated during the same decade. Data were matched to indices using linear regression analyses. RESULTS: We identified 162 894 IBD patients, 59% with ulcerative colitis (UC) and 41% with Crohn's disease (CD). The overall prevalence of IBD was 80 per 100 000, with 46 per 100 000 for UC and 36 per 100 000 for CD. Estimated rates adjusted to total population showed that IBD more than triplicated from 2008 to 2017. The distribution of IBD demonstrated a South-to-North gradient that generally followed population apportionment. However, marked regional differences and disease clusters were identified that did not fit with conventionally accepted IBD epidemiological associations, revealing that the rise of IBD was variable. In some areas, loss of biodiversity was associated with high IBD prevalence. CONCLUSIONS: When distribution is considered in the context of IBD prevalence, marked regional differences become evident. Despite a background of Westernization, hotspots of IBD are recognized that are not explained by population density, urbanicity, sanitation, or other indices but apparently are explained by biodiversity loss. Thus, the rise of IBD in developing countries is not uniform, but rather is one that varies depending on yet unexplored factors like geoecological conditions.
The analysis of a large population of inflammatory bowel disease (IBD) patients in a developing country reveals that the rising prevalence of IBD is not uniform and is linked to factors not traditionally associated with IBD, such as geosocial features and loss of biodiversity.

OBJECTIVES: This clinical trial investigated the efficacy of silver diamine fluoride (SDF) in arresting dentine caries in primary molars of preschoolers. Time required for treatment, adverse effects, parental aesthetic perception, anxiety and oral health related to quality of life (OHRQoL) was evaluated. MATERIALS AND METHODS: Children, 2-5 years old, with active dentine caries lesions on the occlusal surface of primary molars were randomly allocated to test group (SDF) or control group (atraumatic restorative treatment/ART). The dmf-t/DMF-T and ICDAS indexes determined the presence of caries and activity. The main outcome after 3, 6 and 12-month follow-up was assessed by a blind examiner. The time required to perform the treatments was recorded and a facial image scale was applied to assess anxiety before and after treatment. Adverse events and aesthetic perception were assessed through questions addressed to caregivers; and the OHRQoL through the B-ECOHIS questionnaire. RESULTS: In 68 patients that were randomized, the mean number of treated teeth per child was 2.42(1.04) and 2.09(1.18) in the SDF and ART groups (pâ¯=â¯0.074), respectively. The mean difference of arrested lesions between the groups after 12 months was -0,07(0.05; - 0.17-0.30). The time required to treat with SDF was lower than the ART (pâ¯<â¯0.001). There was no difference in the percentage of adverse eventsâ¯+â¯aesthetic perception (pâ¯=â¯0.709), and the change in anxiety (pâ¯=â¯0.155). There was a less impact in OHRQoL after ART treatment, but only when the parents' distress subscale was considered (pâ¯=â¯0.012). CONCLUSION: SDF requires much less chair-time and have similar results as ART in arresting caries lesion, anxiety, adverse effects, aesthetic perception and quality of life.
