Abstract
Background This study aimed to identify a subgroup of recipients at low risk of haemorrhage, bile leakage and ascites following liver transplantation (LT). Methods Factors associated with significant postoperative ascites (more than 10 ml/kg on postoperative day 5), bile leakage and haemorrhage after LT were identified using three separate multivariable analyses in patients who had LT in 2010–2019. A model predicting the absence of all three outcomes was created and validated internally using bootstrap procedure. Results Overall, 944 recipients underwent LT. Rates of ascites, bile leakage and haemorrhage were 34.9, 7.7 and 6.0 per cent respectively. The 90-day mortality rate was 7.0 per cent. Partial liver graft (relative risk (RR) 1.31; P = 0.021), intraoperative ascites (more than 10 ml/kg suctioned after laparotomy) (RR 2.05; P = 0.001), malnutrition (RR 1.27; P = 0.006), portal vein thrombosis (RR 1.56; P = 0.024) and intraoperative blood loss greater than 1000 ml (RR 1.39; P = 0.003) were independently associated with postoperative ascites and/or bile leak and/or haemorrhage, and were introduced in the model. The model was well calibrated and predicted the absence of all three outcomes with an area under the curve of 0.76 (P = 0.001). Of the 944 patients, 218 (23.1 per cent) fulfilled the five criteria of the model, and 9.6 per cent experienced postoperative ascites (RR 0.22; P = 0.001), 1.8 per cent haemorrhage (RR 0.21; P = 0.033), 4.1 per cent bile leak (RR 0.54; P = 0.048), 40.4 per cent severe complications (RR 0.70; P = 0.001) and 1.4 per cent 90-day mortality (RR 0.13; P = 0.004). Conclusion A practical model has been provided to identify patients at low risk of ascites, bile leakage and haemorrhage after LT; these patients could potentially qualify for inclusion in non-abdominal drainage protocols.

Abstract
Abstract
Background
Chile has a high prevalence of obesity (PO), and this has increased even more in recent years. Public health interventions have not impacted, probably because a geographic distribution of the cases at a lower level is unknown. We described the geographic distribution and change of obesity at a sub-regional level in Chile, and to identify targets areas/groups for interventions.
Methods
We did a secondary analysis of the latest two National Health Surveys (2009, 2016), using Regions and Health Service (HS) levels, which are the second and third administrative division of Chile, respectively. HSs were the smallest geographical unit possible to analyze with this data. Logistic regression models were fit to test differences between sex, age, number of children, family income, educational level, regions, and HS, using the lowest value of each variable as the reference group, adjusting by sex and age.
Results
At the national level, PO increased from 25% to 34% from 2009 to 2016. The southern regions have the highest PO in 2016 (Los Rios: 45%, Aysen:44%, Araucania:42%), and the lowest PO is even more than 30%. Although, the highest relative increase was in the north and central regions (Tarapacá:94%, Valparaíso:89%, Coquimbo:62%), as well as their HS. At HS level, in the Metropolitan Region, the PO varies from 21% to 46% in 2016 (OR = 3.3 IC95%1.4-7.9). Likewise, in the Valparaiso Region, it goes from 24% to 44% (OR = 2.9 IC95% 1.2-7). These differences in PO among HS levels in those regions were lower in 2009. Lower family income, educational level, and females with two or more children were associated with obesity in both surveys.
Conclusions
There is a high prevalence and increases in obesity in Chile at national and sub-national levels. The large variability in obesity observed among regions and Health Services suggests that lower geographical areas would be a potential target for effective interventions, complementarity to those at national levels.
Key messages
Analysis and intervention at a subnational level are required for preventing obesity in Chile. The high prevalence of obesity in Chile has a large variability among the subnational levels.

Abstract
Abstract
Background
Biliary leakage remains a major cause of morbidity after liver resection. Previous prognostic studies of posthepatectomy biliary leakage (PHBL) lacked power, population homogeneity, and model validation. The present study aimed to develop a risk score for predicting severe PHBL.
Methods
In this multicentre observational study, patients who underwent liver resection without hepaticojejunostomy in one of nine tertiary centres between 2012 and 2015 were randomly assigned to a development or validation cohort in a 2 : 1 ratio. A model predicting severe PHBL (International Study Group of Liver Surgery grade B/C) was developed and further validated.
Results
A total of 2218 procedures were included. PHBL of any severity and severe PHBL occurred in 141 (6·4 per cent) and 92 (4·1 per cent) patients respectively. In the development cohort (1475 patients), multivariable analysis identified blood loss of at least 500 ml, liver remnant ischaemia time 45 min or more, anatomical resection including segment VIII, transection along the right aspect of the left intersectional plane, and associating liver partition and portal vein ligation for staged hepatectomy as predictors of severe PHBL. A risk score (ranging from 0 to 5) was built using the development cohort (area under the receiver operating characteristic curve (AUROC) 0·79, 95 per cent c.i. 0·74 to 0·85) and tested successfully in the validation cohort (AUROC 0·70, 0·60 to 0·80). A score of at least 3 predicted an increase in severe PHBL (19·4 versus 2·6 per cent in the development cohort, P < 0·001; 15 versus 3·1 per cent in the validation cohort, P < 0·001).
Conclusion
The present risk score reliably predicts severe PHBL. It represents a multi-institutionally validated prognostic tool that can be used to identify a subset of patients at high risk of severe PHBL after elective hepatectomy.

Abstract
BACKGROUND Current data suggest that chemotherapy combinations may be superior to single agents in biliary tract cancer. The epidermal growth factor receptor (EGFR) pathway appears to be associated with tumor stage, prognosis and response to therapy. This trial was designed to evaluate the tolerability and efficacy of the combination of panitumumab, a monoclonal anti-EGFR antibody, with gemcitabine and irinotecan. PATIENTS AND METHODS Patients with advanced (unresectable or metastatic) cholangiocarcinoma, ECOG PS 0-2, and adequate organ function were treated with panitumumab (9 mg/kg) on day 1, and gemcitabine (1000 mg/m(2)) and irinotecan (100 mg/m(2)) on days 1 and 8 of a 21-day cycle. The primary objective was to evaluate the 5-month progression-free survival (PFS). Secondary objectives included overall response rate (ORR) and overall survival (OS). Mutational analyses of EGFR, KRAS and BRAF were carried out when feasible. RESULTS Thirty-five patients received a median of 7 (0-30) cycles. The most common grade 3/4 toxic effects were neutropenia (10 patients, 29%), thrombocytopenia (10 patients, 29%), skin rash (13 patients, 37%) and dehydration (9 patients, 26%). Two patients had CR, 9 had partial response (PR), and 15 had SD for a disease-control rate of 74% (by RECIST) in 28 assessable patients. Two patients went on to have surgical resection. The 5-month PFS was 69%. The median PFS was 9.7 months and the median OS was 12.9 months. In 17 testable samples, no EGFR or BRAF mutations were identified; there were 7 KRAS mutations, with no difference in OS by KRAS status. CONCLUSIONS This study showed encouraging efficacy of this regimen with good tolerability. Further study in this area is warranted. Clinical Trials Number: The trial was registered with the National Cancer Institute (www.clinicaltrials.gov identifier NCT00948935).

Abstract
BACKGROUND Abdominal hernias are a common disease among cirrhotic patients, because of malnutrition and persistently high intra-abdominal pressure due to ascites. When tense ascites is present, life-threatening complications are likely to occur. In such cases, the morbidity and mortality rates are high. OBJECTIVE We describe 3 cirrhotic patients with rare complicated hernias that needed surgical repair. We discuss optimal timing for surgical approaches and the necessity of ascites control before surgery, as well as the technical details of the procedures. METHOD Review of hospital charts of selected rare cases of herniae in cirrhotic patients. CONCLUSION Elective surgical approaches can treat even uncommon hernias in cirrhotic patients with good results.

Abstract
Intensification and expansion of agricultural production since the 1970s have increased soil erosion problems in south-central Chile. Quantitative information on soil loss is needed for erosion risk assessment and to establish the effectiveness of improved land management practices. Since information from traditional sources, such as erosion plots, is limited, attention has been directed to the use of environmental radionuclides for documenting erosion rates. Cs-137 has been successfully utilised for this purpose, but only provides information on medium-term erosion rates. There is also a need to document event-related soil erosion. This paper outlines the basis for using (7)Be measurements to document short-term erosion and reports its successful use for quantifying the erosion that occurred within an arable field, as a result of a period of heavy rainfall (400mm in 27 days) occurring in May 2005. The study field had been under a no-till, no-burning system for 18 years, but immediately prior to the period of heavy rainfall the harvest residues were burnt. The erosion recorded therefore reflected both the extreme nature of the rainfall and the effects of the burning in increasing surface runoff and erosion. The sampled area corresponded to that used previously by the authors to document the medium-term erosion rates associated with both conventional tillage and the subsequent switch to a no-till system. Comparisons between the erosion documented for the period of heavy rainfall in 2005 with these medium-term erosion rates permits some tentative conclusions regarding the importance of extreme events and the impact of burning in increasing the erosion associated with the no-till system.

Abstract
BACKGROUND The relationship between Helicobacter pylori infection and its treatment and gastro-oesophageal reflux disease (GERD) is controversial. AIMS To establish if H. pylori infection is associated with the presence of GERD and if anti-H. pylori treatment leads to de novo GERD or rebound/exacerbation of GERD. METHODS A search of MEDLINE and EMBASE databases was made. Pooled odds ratios (OR) were calculated for de novo GERD and rebound/exacerbated GERD after anti-H. pylori therapy in case-control studies and in therapeutic trials. RESULTS Fourteen case-control studies and 10 clinical trials were included. Among case-control studies, pooled OR for the association between H. pylori negative status and GERD was 1.34 [95% confidence interval (CI) 1.15-1.55]. Among therapeutic trials, pooled OR for the association anti-H. pylori therapy - GERD was 2.54 (95% CI 1.92-3.37). The OR for de novo GERD was 3.25 (95% CI 2.09-5.33), and for rebound/exacerbated GERD was 2.39 (95% CI 1.75-3.34). Associations were higher among Asian studies than among North American and European studies. CONCLUSIONS This meta-analysis shows significant association between absence of H. pylori infection and GERD symptoms, and a positive association between anti-H. pylori therapy and occurrence of both de novo and rebound/exacerbated GERD. The significance of these associations appears to have been inflated by the effect of single trials and by geographical variations.

Abstract
OBJECTIVE Different types of chronic gastritis, including antral predominant, corpus predominant, and multifocal pangastritis, are associated with Helicobacter pylori infection. Specific patterns of H. pylori gastritis that might characterize individuals with family histories of noncardia gastric cancer (GC) were investigated. METHODS Histopathological changes associated with H. pylori gastritis were assessed in 111 individuals with family histories of GC and in 77 without from a region with high prevalence of H. pylori infection and GC. Gastric biopsies were taken from 12 sites (antrum, five; corpus, six; and cardia, one). RESULTS Individuals (age < 36 yr) with family histories of GC developed pangastritis and had higher H. pylori bacterial scores (p < 0.05) in the gastric corpus, whereas those without family histories of GC typically had antral predominant gastritis. The correlation between density of polymorphonuclear leukocytes and density of H. pylori at each biopsy site was statistically significant (p < 0.01). Pangastritis was associated with a higher density of lymphoid aggregates and follicles (p < 0.05) in the corpus of younger individuals (age < 36) and in the antrum of older individuals (age > or = 48) with positive family histories of GC. CONCLUSIONS Pangastritis and high lymphoid follicle density associated with H. pylori infection were found in patients with family histories of GC. Because a family history of gastric carcinoma is associated with increased risk of gastric cancer development, characterization of histological patterns of gastritis may be applicable to gastric cancer screening and surveillance, especially in relatively young at-risk populations.

Abstract
This study was conducted to identify the domestic mite fauna of Puerto Rico. A total of 57 dust samples were collected from mattresses in homes of 11 cities on the Island. The analysis of the samples revealed that 73.70% of the mattress samples had at least one mite species. The identified species include: Dermatophagoides pteronyssinus (45.6%), Blomia tropicalis (31.6%), Cheyletus sp. (19.3%), Dermatophagoides farinae (17.5%), Euroglyphus maynei (5.3%), Dermatophagoides sibonei (1.8%), Dermatophagoides sp. (1.8%), Suidasia melanensis (1.8%) and mite species that were not identified (5.3%). Differences in the geographical distribution of mites showed that only Blomia tropicalis is more frequently in the northern (43%) than in the southern region (19%) of Puerto Rico (OR 3.36, p, 0.046). This finding can be explained by the fact that in the northern region the relative humidity is significantly higher that in the southern region (p < 0.001). No significant differences were observed for other species or in the total mite counts between the northern and southern regions. The small sample size of this study may explain the lack significance for some of the differences found. Nevertheless, our results indicate that the domestic mite fauna is composed of several clinically important species, their numbers are high enough to be considered in the sensitizing levels, and the diversity of these species is comparable to other observations in the Caribbean areas, and in the southern states in the continental US. Based upon our results, we recommend that when performing the skin test in Puerto Rico, extracts from the identified local domestic mite species be included in the allergen panel. This may prove useful in the aid for the diagnosis and management of atopic conditions.

Abstract
Anatomic and topographic studies were carried out in 30 recurrent laryngeal nerves (RLN), dissecting the vagus nerve retrogradely to identify corresponding fascicles to the RLN. By obtaining measurements of diameter and length, surgically practical data were obtained, allowing for a possible revision of reconstructive possibilities for nerve injuries to the RLN through dissection and nerve graft.

Abstract
We retrospectively analyzed the gastrointestinal complications observed in 119 patients who had ingested corrosive agents. Hydrochloric acid and sodium hydroxide were the agents involved in 62% of patients. Women predominated over men (p less than 0.001); mean age was 36 for males and 29 for women (p less than 0.05). Endoscopy was performed in 55% of patients and revealed acute lesions in 69%. Complications were observed in 18% of patients requiring surgery in 12 (10%). Main complications included sepsis of abdominal or mediastinal origin and gastrointestinal bleeding. Mortality among these patients was 73%.

Abstract
To determine the role of Vibrio cholerae as a cause of diarrheal illness in Cancun, Mexico, an investigation was conducted in July and August 1983. Although toxigenic V. cholerae 01 were not found, non-01 V. cholerae were isolated from 22 (16%) of 134 stools from persons with diarrheal illness and none of 22 stools from well persons; 58 (92%) of 63 sewage samples; 12 (86%) of 14 untreated well water samples; a home storage tank for treated water; and 5 (21%) of 24 samples of raw seafood. None of the V. cholerae isolates from patients were toxigenic. The illness occurred mainly in small children, and were characterized principally by diarrhea and abdominal pain. No patient was seriously ill, and all recovered without sequelae. Seven different serotypes of non-01 V. cholerae were isolated from the stool specimens, and Smith serotype 12 accounted for 10 (46%) of the 22 isolates. A matched-pair case-control study found that cases were more likely than controls to have eaten home prepared gelatin (P = 0.03, OR = 5/0) and seafood (P = 0.06, OR = 4/0).

Abstract
The purpose of this study has been to review the late results of surgical treatment of 244 patients with endoscopically proved benign chronic gastric ulcer located 5 cm or less from the cardia. In five patients, a total gastrectomy with esophagojejunostomy was performed. Proximal gastrectomy was used in 3 patients, mesogastrectomy in 5 patients, a partial Schoemaker's procedure in 73 patients, Pauchet's procedure in 70 patients, and Csendes' procedure in 23 patients. Nonresective procedures were employed in 67 patients and included the Kelling-Madlener procedure in 23 patients, pyloroplasty alone in 10 patients, gastrojejunostomy alone in 4 patients, local or wedge excision of the ulcer in 9 patients, and vagotomy and pyloroplasty in 21 patients. The follow-up evaluation was performed in 91 percent of the patients (mean 9 years postoperatively, range 5 to 15 years), with emptying endoscopy in all nonresected patients. A high mortality was observed after total or proximal gastrectomy, as well as after nonresective procedures. After the other resective techniques, low postoperative morbidity and mortality were observed. No recurrent ulcer was seen after the resective procedures. Based on these results, we propose that when the ulcer is located 5 cm below the cardia, Schoemaker's or Pauchet's procedure should be performed; if the ulcer is located 2 cm or less from the cardia, Csendes' procedure or the Kelling-Madlener procedure should be employed.

Abstract
Gallbladder intraluminal pressures were determined during operation in 22 patients with chronic unobstructed cholecystitis and 25 patients with acute unobstructed cholecystitis by means of a glass manometer connected to a needle. Patients with chronic cholecystitis had a mean resting value of 9.9 +/- 0.9 cm H2O, and patients with acute cholecystitis had a mean fasting value of 36.0 +/- 1.8 cm H2O (p less than 0.001). The importance of these findings is discussed.
