This study is aimed at the mechanisms used by students with an intellectual disability in the counting process. The assessment of the counting process is carried out through experimental tests inspired by the basic principles of Gelman and Gallistel, namely one-to-one, stable order, cardinality, abstraction and order irrelevance. This is a comparative study of participants with a developmental age of between 4 and 5 years, in two populations: a group of students with intellectual disability attending special education (SEN) schools, with chronological ages of between 8 and 12 years, whose developmental age was determined by the Cambrodi Dimensional Method, and another group of students without intellectual disability attending mainstream schools (MS). The data do not show significant differences between the one-to-one and stable order principles with respect to the variables MS and SEN, while significant differences are demonstrated for the principles of cardinality, abstraction and order irrelevance. (Contains 8 tables and 6 figures.)

Introduction: Acute gastroenteritis (AGE) represents a significant global health burden, with enteric viruses being a leading cause of gastroenteritis worldwide. Despite advances in diagnosis and treatment, there are limited data on adults seeking care due to AGE of viral etiology. This study aimed to describe the etiological, clinical, and epidemiological characteristics of viral AGE in adult patients presenting for medical consultation in a tertiary hospital over a 2-year period., Methods: A retrospective cross-sectional study was conducted, with 8886 stool samples from 8356 adult patients presenting acute diarrhea between January 2021 and December 2022. A molecular real-time RT-PCR panel was used to screen for common bacterial, parasitic, and viral pathogens. Clinical and demographic data were collected, and statistical analysis was performed to evaluate possible associations., Results: Enteric viruses constituted 10.3% (307 cases) of all AGE of known etiology, with norovirus being the predominant pathogen (196, 63.8%), followed by rotavirus (82, 26.7%) and adenovirus (29, 9.4%). The different viruses showed a distinct seasonal predominance. Coinfection with other microorganisms was common. Most cases exhibited a self-limiting course. Mortality and hospitalization rates were high in patients with higher comorbidity indices, mainly in individuals with immunosuppression., Conclusions: Viruses are an important cause of acute gastroenteritis in adults presenting for medical consultation. The new multiplex molecular tests with high sensitivity and specificity allow early differential diagnosis in AGE. It is therefore necessary to identify which special populations particularly with higher comorbidity indices, would benefit from the implementation of these techniques, to guide decision-making related to appropriate treatments and avoid unnecessary interventions., Competing Interests: Declarations. Conflict of interest: All authors (Sara Herranz-Ulldemolins, Anna Sellarès-Crous, Miriam J Álvarez-Martínez, M Eugenia Valls, Marta Aldea Novo, Anna Vilella Morató, Laura Rodriguez, Mireia Navarro, Roser Vendrell, Josep Barrachina, Miguel J Martínez and M Ángeles Marcos) have nothing to disclose. Ethical Approval: The study was approved by the Research Ethics Committee of the Hospital Clínic of Barcelona (HCB/2023/0496). The data in the database were de-identified and were analyzed under the Biomedical Research Act 14/2004.

Objective: Inflammatory Bowel Disease has increased in Hispanics. This study estimates its prevalence in Puerto Rico for 2013 and compares it with prior reports., Methods: The database of commercial and government insurance claims of the Department of Health for 2013 was used. A case was defined as having at least two medical claims of outpatient services or one or more hospitalizations and emergency department visits with an ICD-9 code for Crohn's disease or ulcerative colitis. Cases with codes for both were classified as undetermined inflammatory bowel disease. Prevalence was calculated for inflammatory bowel disease, Crohn's disease, and ulcerative colitis overall and by age, sex, and health insurance., Results: 5,378 persons were classified as having inflammatory bowel disease, for an overall prevalence of 181.54/100,000. Of these, 2,154 had Crohn's disease and 2,689 had ulcerative colitis, with prevalences of 72.71 and 90.77/100,000 respectively. Crohn's disease was more prevalent in males and ulcerative colitis in females. Both types were more prevalent in the government insured population. 719 children had inflammatory bowel disease, for a prevalence of 89.8/100,000. Of these, 480 were classified as Crohn´s disease and 169 as ulcerative colitis. Prevalences for pediatric Crohn's disease and ulcerative colitis were 60.0 and 21.2/100,000 respectively., Conclusion: When compared with a report for 2005, the prevalence for inflammatory bowel disease in Puerto Rico for 2013 showed a 4-fold increase overall and a 3-fold increase in children. Inflammatory bowel disease was more prevalent in government-insured as opposed to commercially insured persons, in contrast with previous findings.

The Puerto Rico population may be modeled as an admixed population with contributions from three continents: Sub-Saharan Africa, Ancient America, and Europe. Extending the study of the genetics of inflammatory bowel disease (IBD) to an admixed population such as Puerto Rico has the potential to shed light on IBD genes identified in studies of European populations, find new genes contributing to IBD susceptibility, and provide basic information on IBD for the care of US patients of Puerto Rican and Latino descent. In order to study the association between immune-related genes and Crohn's disease (CD) and ulcerative colitis (UC) in Puerto Rico, we genotyped 1159 Puerto Rican cases, controls, and family members with the ImmunoChip. We also genotyped 832 subjects from the Human Genome Diversity Panel to provide data for estimation of global and local continental ancestry. Association of SNPs was tested by logistic regression corrected for global continental descent and family structure. We observed the association between Crohn's disease and NOD2 (rs17313265, 0.28 in CD, 0.19 in controls, OR 1.5, p = 9×10-6) and IL23R (rs11209026, 0.026 in CD, 0.0.071 in controls, OR 0.4, p = 3.8×10-4). The haplotype structure of both regions resembled that reported for European populations and "local" continental ancestry of the IL23R gene was almost entirely of European descent. We also observed suggestive evidence for the association of the BAZ1A promoter SNP with CD (rs1200332, 0.45 in CD, 0.35 in controls, OR 1.5, p = 2×10-6). Our estimate of continental ancestry surrounding this SNP suggested an origin in Ancient America for this putative susceptibility region. Our observations underscored the great difference between global continental ancestry and local continental ancestry at the level of the individual gene, particularly for immune-related loci.

Background: Evaluation of ethnic and racial patterns of Inflammatory Bowel Disease (IBD) has demonstrated a higher incidence of IBD in Jews, and lower rates in blacks and Hispanics when compared to whites. There is limited data describing incidence and prevalence among Hispanics, the fastest growing minority in the United States., Methods: To estimate the prevalence of IBD computerized records of all physicians billing and hospital discharges classified with ICD-9-CM IBD related codes were searched. Prevalence was estimated by age group, sex, and type of insurance (commercial versus government-sponsored managed care)., Results: Of 1,248,993 insured individuals in 2005, 186 had a diagnosis of Crohn's disease and 291 of ulcerative colitis. The estimated prevalence per 100,000 was 14.9 for Crohn's disease, 23.3 for ulcerative colitis, and 38.2 cases for IBD. The most significant difference was found when comparing insurance type, with a total IBD prevalence rate of 61.75 cases among commercial versus 14.36 cases among government-sponsored insured., Conclusions: The prevalence of IBD in this insured population in Puerto Rico places it among the highest described in a Hispanic population. Given the continued rise in prevalence of IBD and the limited studies describing the epidemiology of IBD in Hispanics, further studies which may provide important clues to the etiology of the disease as well as valuable information for appropriate health care planning are important.

Choledochal cyst type II, is an extremely rare cause of portal hypertension, severe pancytopenia in an adult patient, and a complication of long-standing disease. We present an uncommon cause of portal hypertension in a young female patient secondary to an obstructive choledochal cyst type II provoking massive splenomegaly and severe pancytopenia. A high level of clinical suspicion is important due to its high mortality rate if it remains undiagnosed. To our knowledge there are few publications describing this rare type of choledochal cyst in a Hispanic adult.

Objective: To review the experience with ileal pouch-anal anastomosis surgery for ulcerative colitis at the University Hospital., Background: As many as 40% of patients with ulcerative colitis (UC) and 75% with Crohn's disease (CD) require some surgery for their disease. The number of patients referred to our clinics for evaluation and management of Inflammatory Bowel Disease (IBD) has risen in the past seven years. A multidisciplinary IBD service has been created at the University Hospital for the care of these patients, leading to a dramatic increase in the number of surgeries performed for IBD. Over the past decade the ileal pouch-anal anastomosis (IPAA) has emerged as the procedure of choice in most patients with ulcerative colitis requiring total colectomy for management of their disease. Even though the procedure is associated with a considerable morbidity rate, it has become very popular since it avoids the need for a permanent stoma and presumably rids the patient of disease and subsequent cancer risk., Results: Twenty-five patients were identified as having IPAA for ulcerative colitis between 1993-2000. Indications for surgery were intractability and toxic megacolon. Complications were pouchitis in 11/25 (44%), anastomotic stricture in 6/25 (24%), small bowel obstruction in 4/25 (16%), and pouch failure in 2/25 (8%). Other complications included wound abscess in 1/25 (4%), and sexual dysfunction in 1/25 (4%) patients. There was no mortality; the patients' quality of life was rated as greatly improved in 14 of 17 patients interviewed (82.4%) and 16 of 17 said they would recommend the surgery to others (94.1%)., Conclusions: The results of IPAA surgery, morbidity, mortality, and patient satisfaction in our series were similar to other centers around the world.

Presentation of two clinical cases of spontaneous vesical rupture secondary to bacterial cystitis in elderly patients. One corresponds to an intraperitoneal perforation while the second case was extraperitoneal. The patients were, in both cases, diabetic women admitted in emergency due to acute abdomen. We considered that although vesical perforation secondary to bacterial cystitis is a very uncommon process, it should be taken into account in the differential diagnosis of acute abdomen in predisposed patients (diabetic elderly patients with pyuria). In such instances, a retrograde cystography would provide the diagnosis. Although extraperitoneal vesical perforations can be resolved with a vesical catheter or cystostomy, extravasation of the infected urine may result in a perivesical abscess and septic shock. Early surgical management should be considered in these cases.

A total of 84 radical cystectomies were performed for invasive bladder cancer in 67 men (79.8%) and 17 women (20.2%). The present study investigated the possible sex-dependent differences in the pattern of invasive bladder cancer. More than 40% of the women presented lower urinary tract syndrome alone or with haematuria, giving a clinical picture similar to acute cystitis. This caused an average time-lag in diagnosis of 18.5 months in the women and 8 months in the men. There was a higher frequency of non-transitional cell carcinoma in the women (17.6%) than in the men (2.9%). We found statistically significant differences (p < 0.005) in tumor grade: 35.2% of the women had low grade tumors, compared to 7.4% of the men. However, no significant differences in staging or survival rate were found when comparing the two sexes. This leads us to believe that bladder cancer is less aggressive in women.
