Incidence of herpes zoster in patients with inflammatory bowel disease. / Incidencia de herpes zóster en pacientes con enfermedad inflamatoria intestinal: estudio observacional y retrospectivo en dos hospitales españoles de tercer nivel.

BACKGROUND: Herpes zoster (HZ) is a prevalent disease caused by the reactivation of the varicella-zoster virus (VZV) and associated with chronic morbidity, particularly with post-herpetic neuralgia (PHN). Inflammatory bowel disease (IBD) has been associated with an increased risk of HZ, mainly when immunosuppressive treatment (IMT) is used. However, studies assessing the risk of HZ in IBD are scarce. AIMS: To evaluate the incidence rate and risk factors of HZ in IBD. METHODS: Retrospective study in IBD patients with a positive VVZ serology from two referral hospitals from the area of Barcelona. Diagnosis of HZ and its clinical features were recorded. RESULTS: A total of 398 IBD patients with a positive IgG-VVZ serology were identified. Fifty-eight percent of the patients received IMT (46.5% immunosuppressants monotherapy, 20.6% biologics monotherapy and, 32.7% combination therapy). After a median follow-up of 71 months (IQR 41.5-138.0), 17 (4.3%) patients developed HZ (cumulative incidence of 5.2 per 1000 person-year), 12 of them (70.6%) while receiving IMT. Median age at HZ episode was 38 years (IQR 27.5-52.5). Two (11%) developed PHN. Biological therapy was the only risk factor for developing HZ (OR 3.8 IC 95% 1.3-11.5; p=0.018). CONCLUSIONS: HZ is quite prevalent in IBD, occurring at early ages and particularly among patients using IMT. NPH appears to occur in a notable proportion of cases.

Predicting attachment in Portuguese infants born very or extremely preterm: Understanding the roles of infant regulatory behavior, maternal sensitivity, and risk factors.

A growing body of research shows that early attachment relationships are foundational for children's later developmental and psychosocial outcomes. However, findings are mixed regarding whether preterm birth predicts later attachment, but insecurity is generally more prevalent among infants at higher medical and/or social/familial risk. This longitudinal study aimed to identify specific relational, familial/demographic, and perinatal predictors of attachment in a sample of 63 Portuguese infants born very or extremely preterm (VEPT, <32 gestational weeks) and their mothers from diverse socioeconomic backgrounds. One-third of the mothers had social/family risk factors (e.g., single parent, immigrant, unemployed, low education, and/or low income). At 3 months (corrected age), dyads were observed during social interaction in the Face-to-Face Still-Face paradigm (FFSF) and during free play. At 12 months, mother-infant dyads were observed in Ainsworth's Strange Situation. Over half (58.7%) of the infants were classified as insecurely attached. Social-Positive Oriented regulatory behavior pattern, higher maternal sensitivity, higher infant cooperation during free play, number of siblings and an absence of social/family risk factors were associated with attachment security. Perinatal variables were unrelated to attachment. Findings indicate that both relational and social contextual factors contribute to attachment in this biologically vulnerable sample.

Un creciente cuerpo investigativo muestra que las relaciones afectivas tempranas son fundamentales para posteriores resultados de desarrollo y sicosociales de los niños. Sin embargo, los resultados son variados acerca de si el nacimiento prematuro predice la afectividad posterior, pero la inseguridad es generalmente más prevalente entre infantes bajo más alto riesgo médico y/o social/familiar. Este estudio longitudinal se propuso identificar factores específicos de predicción de la afectividad, relacionales, familiar/demográficos y perinatales en un grupo muestra de 63 infantes portugueses nacidos muy o extremadamente prematuros (VEPT, < 32 semanas gestacionales) y sus madres de diversos niveles socioeconómicos. Un tercio de las madres tenían factores de riesgo social/familiar (v.g. madre soltera, inmigrante, desempleada, de baja educación y/o de bajos recursos económicos). A los tres meses (edad corregida), se les observó a las díadas durante la interacción social en el paradigma de Cara a Cara y Rostro Inmutable (FFSF) y durante el juego libre. A los 12 meses, se les observó a las díadas madre-infante por medio de la Situación Extraña de Ainsworth. Se clasificó más de la mitad (58.7%) de los infantes como afectivamente inseguros. Entre los factores de predicción de la afectividad segura se incluyó un patrón de conducta regulatoria con orientación social positiva durante FFSF, una sensibilidad materna más alta y la cooperación del infante durante el juego libre, así como la ausencia de factores de riesgo sociales/familiares. Las variables perinatales no estuvieron relacionadas con la afectividad. Los resultados indican que los factores contextuales, tanto relacionales como sociales contribuyen a la afectividad en este grupo biológicamente vulnerable.

Mother-infant bonding: The role of postpartum depression, violence, and bonding established with one's own mother during childhood.

Mother-infant bonding is influenced by several risk and protective factors, and the literature has investigated the relationships between these factors independently. This study aimed to verify the interrelationships of some of these factors and how they influence mother-infant bonding in Brazil. In this study, 361 mothers participated, and the outcome variable of mother-infant bonding was assessed using the Postpartum Bonding Questionnaire (PBQ). Multivariate regression analysis was performed using a hierarchical model with three blocks structured according to the influence exerted on mother-infant bonding. The PBQ's factor scores were estimated and used in the subsequent analyses to decrease measurement error. The variable "violence experienced by mothers" was statistically significant for explaining the second block model but not significant for the third block. Network analysis was performed after multiple regression, showing that the violence experienced by mothers does not directly influence mother-infant bonding but rather is mediated by postpartum depression. This explains why violence is not significant in the hierarchical multiple regression when maternal depression is added to the model. This study's strengths lie in its utilization of PBQ factor scores and network analysis, enabling the estimation of conditional relationships among variables. This approach provides deeper insights into factors affecting mother-infant bonding.

Varios factores de riesgo y de protección ejercen influencia sobre la unión afectiva madre­infante; la literatura disponible ha investigado las relaciones entre estos factores de una manera independiente. Este estudio se propuso verificar las interrelaciones de algunos de estos factores y cómo ellos influyen en la unión afectiva madre­infante. Se consultó un total de 361 madres y el variable resultado de afectividad madre­infante se evaluó por medio del Cuestionario de Afectividad de Postparto (PBQ). Se llevaron a cabo análisis de regresión multivariados usando un modelo jerárquico con tres estructuras de bloques de acuerdo con la influencia ejercida sobre la unión afectiva madre­infante. Se estimaron y usaron los puntajes de factores del PBQ en los análisis subsecuentes para disminuir el error en la medida. La variable "violencia experimentada por las madres" fue estadísticamente significativa para explicar el segundo modelo de bloque, pero no significativa para el tercer bloque. Se llevó a cabo un análisis de interrelaciones después de la regresión múltiple, demostrando que la violencia experimentada por las madres no influye directamente la afectividad madre­infante, sino que la misma es mediada por la depresión posterior al parto. Esto explica por qué la violencia no es significativa en la jerárquica regresión múltiple cuando la depresión materna se le agrega al modelo. Entre los puntos fuertes de este estudio se incluye el uso de los puntajes de factores del PBQ y el análisis de interrelaciones, lo cual permitió que se estimaran las relaciones condicionales existente dentro del grupo de variables, aportando una mayor comprensión de algunos factores que interfieren en la unión afectiva madre­infante.

Distribution, seroprevalence and risk factors for bovine brucellosis in Brazil: Official data, systematic review and meta-analysis.

Bovine brucellosis is an endemic disease in Brazil, and evidence-based assessments of the available literature on its seroprevalence and risk factors are limited. The aim of this study was to systematically review and summarize studies related to seroprevalence and risk factors of bovine brucellosis in the entire Brazil, in addition to comparing published data with the most recent official reports. Articles available in scientific databases and published between October 2006 and October 2021 were evaluated. Forty-five publications were included in the meta-analysis on the seroprevalence of brucellosis and 29 publications in the review on risk factors. The largest number of publications was found for the State of Mato Grosso do Sul (n=4), and the highest and lowest seroprevalences were observed in Acre (11%; 95% CI: 8.0-14.0%) and in the Federal District (0.4%; 95% CI: 0.2-0.7%). The main risk factors were the purchase of animals for breeding, vaccination, the number of heifers (female ≥2 years), the presence of calving paddocks and the occurrence of abortions. The need for new official studies has been suggested to determine the true prevalence of bovine brucellosis in Brazil, supported by the National Program for the Control and Eradication of Animal Brucellosis and Tuberculosis.

Wakabayashi & Daimon cardiometabolic index as an indicator to assess risk in adults. A systematic review.

OBJECTIVE: To analyze the Wakabayashi & Daimon (2015) equation, as a predictive indicator of cardiometabolic diseases and its comparison with other indices. DESIGN: A systematic review was carried out between January and March 2023, according to the PRISMA statement. DATA SOURCE: Scopus, Web of Science, and PubMed databases were reviewed using "cardiometabolic index" (CMI) as the search term. STUDY SELECTION: The following inclusion criteria were determined: studies in adults with cardiometabolic diseases using the Wakabayashi & Daimon (2015) CMI formula in different populations; studies that validate or compare the equation or that demonstrate the effects of the intervention. DATA EXTRACTION: Of the 11 selected articles, the characteristics of the population, type of study, indicators for the validation of the CMI, the reported statistics and the conclusions that were recorded in a comparative table were obtained. RESULTS AND CONCLUSIONS: Odds ratio, hazard ratio, sensitivity, and specificity were used to assess associations, risk, effectiveness, and validity of the tests, indicating favorable relationships between the factors analyzed and the results obtained. Validation and probabilistic analysis of the CMI were performed against diverse diseases such as obesity [Man >60y=AUC=0.90 (0.75-1.00) (p=0.01), Se=100, Sp=81.8, YI=0.82 and OR 4.66 and Women >60y=AUC=0.95 (0.88-1.00), p=0.001, Se=90.0, Sp=100, YI=0.90 and OR=36.27]; cardiovascular diseases [AUC=0.617, Se=0.675, Sp=0.509; HR=1.48 (1.33, 1.65), p=<0.001], among others. In conclusion CMI is a new utility index that broadly identifies the presence of risk that leads to cardiometabolic diseases in adults.

[Cardiometabolic effects of weight loss]. / Efectos cardiometabólicos de la pérdida de peso.

The prevalence of overweight and obesity, and, consequently, associated comorbidities, is increasing significantly worldwide. The guidelines recommend a percentage of weight loss> 5% to achieve beneficial effects on metabolic comorbidities associated with obesity. Furthermore, greater weight losses (> 10%) produce more significant improvements, and may even produce remission of some of these comorbidities. In this chapter, we review the evidence of the effect of weight loss through different strategies (lifestyle intervention, pharmacological treatment, or bariatric surgery) on the main cardiometabolic pathologies associated with excess adipose tissue (type 2 diabetes, high blood pressure, dyslipidemia, metabolic dysfunction-associated steatotic liver disease, inflammation, cardiovascular diseases, and mortality).

[Breastfeeding in Spain and the factors related to its establishment and maintenance: LAyDI Study (PAPenRed)]. / Lactancia materna en España y factores relacionados con su instauración y mantenimiento: estudio LAyDI (PAPenRed).

OBJECTIVE: To find out actual statistics on breastfeeding in Spain, as well as sociocultural and perinatal factors that affect its initiation and maintenance. DESIGN: Prospective, multicentre, longitudinal, nationwide study (XXX study). SITE: Primary care paediatricians' office. PARTICIPANTS: Cohort of newborns born between April 2017 and March 2018 in Spain who were followed up to two years of age in 8 visits. MAIN MEASURES: Rates of different types of breastfeeding were analysed at each visit and variables related to gestation, delivery, neonatal period, social, economic and biological variables were also analysed. RESULTS: Initial sample of 1946 (50.1% male). 90.7% decided to initiate breastfeeding at birth. Exclusive breastfeeding (EBF) was 66.4% at 15days and 35.2% at 6months. Any type of breastfeeding (total breastfeeding [TBF]) at 6months was 61.7%. Median survival from TBF was 6.0months (95%CI: 6.0-6.1). Variables related to EBF at 15days: previous children, mother's level of education, absence of illness during pregnancy, no separation of mother and child at birth, no dummy use, no nipple problems, and time of decision to breastfeed. Variables related to longer duration of TBF: relationship of parents older than 5years, no dummy use, co-sleeping at one month of life, deciding to breastfeed before pregnancy, receiving information on breastfeeding during pregnancy and using support from associations. CONCLUSIONS: Early abandonment of breastfeeding is a major problem in Western societies. There are factors that can be worked on to improve outcomes.

[Cardiovascular prevention in primary care in crisis situations: multicenter comparative study before, during and after the SARS-COVID-19 pandemic]. / Prevención cardiovascular en Atención Primaria en situación de crisis: estudio comparativo multicéntrico antes, durante y después de la pandemia por SARS-COVID-19.

OBJECTIVE: To assess whether the appearance of a crisis situation such as the one caused by the SARS-COV-2 pandemic, together with the organizational changes adopted in Primary Care, have influenced the implementation of cardiovascular preventive activities in patients aged 40 to 74 years. DESIGN: Retrospective multicenter descriptive study for three years (2019-2022) in Primary Care. SETTING: 35 health centers of the Primary Care of the Northern Assistance Directorate of Madrid. PARTICIPANTS: 1008 patients of both sexes between 40 and 74 years with diagnosed of hypertension, Diabetes Mellitus and/or dyslipidemia. METHOD: The variables analyzed from the computerized clinical history were lifestyle activities (consumption of tobacco, alcohol, consumption of Mediterranean diet and exercise) considering 3 of the 4 parameters optimal; examination data (blood pressure record) and analytical record (glycemia, hbA1c, total cholesterol, HDL, LDL)considering 4 of the 5 parameters optimal. Differences are analyzed between based pre-pandemic (03/15/2019-03/14/2020), pandemic (03/15/2020-03/14/2021), and transition (03/15/2022-03/14/2022). STATISTICAL ANALYSIS: MC Nemar's test to compare the main variables between the study periods. RESULTS: Data from 1008 patients are collected. The registration of preventive activities on lifestyle was 180 patients (17.9%) (IC95%: 0,155-0,204) in pre-pandemic, 29 patients (2.9%) (IC 95%: 0,019-0,041) in pandemic and 55 patients (5.5%) (IC 95%: 0,041-0,070) in the transition stage (p < 0.05). Exploration was registered in 393 patients (39%) (IC95%: 0,360-0,421) in the pre-pandemic, 133 patients 13,2% (IC 95%: 0,112-0,154) in the pandemic, and 218 patients (21,6%) (IC 95%: 0,191-0,243) in the transition (p < 0.05). The analytical record was 33 patients (3.3%) (IC955: 0,023-0,046), 10 patients (1%) (IC95%: 0,005-0,018) and 23 patients (2.3%) (IC95%: 0,015-0,034) respectively in each phase with one (P < 0.05). CONCLUSIONS: Activities on lifestyle, physical examination, and laboratory test as part of the cardiovascular prevention strategy are scarce in the prepandemic period and decrease drastically during the pandemic, at the first level of care.

[Malnutrition and obesity in self-sufficient elderly and health determinants related to both nutritional disorders]. / Desnutrición y obesidad en mayores autónomos y determinantes de salud relacionados con ambos trastornos nutricionales.

OBJECTIVE: Evaluate the nutritional status in older adults in the community, to determine malnutrition, obesity and their risks and to identify determinants related to both clinical situations. DESIGN: Cross-sectional study. SITE: 3 Primary care health centers in La Rioja in urban, semiurban and rural areas. PARTICIPANTS: 409 people ≥ 65 years old who came to receive consultation, with 3 abandonments. INTERVENTIONS: Nutritional assessment by tools screening and anthropometric measurements. MAIN MEASUREMENT: The MNA SF® was used to determine the prevalence of malnutrition and the BMI for obesity. Sociodemographic, socioeconomic, health-disease variables, lifestyle habits, metabolic status, and anthropometric measurements were included. Binary logistic regression was performed to predict dichotomous dependent variables. RESULTS: The prevalence of malnutrition and its risk (DR) were 18.7% and obesity and its risk were 66,5%. The multivariate model for malnutrition and DR includes polypharmacy, dyslipidemia, sedentary lifestyle, and having mental pathology (OR=3.09, 2.01, 2.12, 1.72, respectively). On the other hand, the probability of presenting obesity is associated with cardiovascular risk, age, excessive-moderate alcohol consumption, hypertension and low adherence to the Mediterranean diet (OR=2.73, 4.27, 2.03, 1.97, 1.81 respectively). CONCLUSION: This results stand out that the study population has a poor nutritional status, detecting a risk of malnutrition, obesity and overweight. The identified predictors related to lifestyle habits, presence of diseases, psychosocial problems, metabolic alterations, etc. They can guide the selection of those people who would benefit from screening to detect and approach the risk of malnutrition early.

Association between suicidal behavior and symptoms of other mental health problems in Mexican adolescents.

BACKGROUND: Suicidal behavior in adolescents is a growing public health problem. Knowing its risk factors is key for reducing it. OBJECTIVE: To identify the relationship between two suicidal behaviors (ideation and attempt) and eight mental health problems (MHPs) in Mexican adolescents. MATERIAL AND METHODS: Through an online survey of adolescent students from 20 states, the following information was screened: symptomatology of six MHPs (affective problems/depression, behavioral problems, somatic problems, inattention and hyperactivity problems, oppositional defiant problems and anxiety problems) and suicidal behavior (suicidal ideation and suicide attempts). MHP and suicidal behavior frequencies and percentages were analyzed, and associations were sought using binary logistic regression. RESULTS: Six-thousand seven hundred sixty-six adolescents completed the survey, out of whom 61.02% were females, with ages ranging between 11 and 19 years (16.38 ± 1.33); 10% reported suicidal behavior, and between 3 and 5%, MHPs. The predictors (χ2(8) = 387.13, p < 0.001) of suicidal behavior were affective problems/depression, behavioral problems, somatic problems, oppositional defiant problems and anxiety problems. CONCLUSION: Five mental health problems increased the risk of reporting suicidal behaviors.

ANTECEDENTES: Las conductas suicidas en adolescentes son un problema de salud pública que va en aumento. Conocer sus factores de riesgo es clave para reducirlas. OBJETIVO: Identificar la relación entre dos conductas suicidas (ideación e intento) y ocho problemas de salud mental (PSM) en adolescentes mexicanos. MATERIAL Y MÉTODOS: Mediante una encuesta en línea a adolescentes escolarizados de 20 estados, se tamizó la siguiente información: sintomatología de seis PSM (problemas afectivos/depresión, problemas conductuales, problemas somáticos, problemas de inatención e hiperactividad, problemas oposicionistas desafianes y problemas de ansiedad) y conducta suicida (ideación e intentos de suicidio). Se analizaron frecuencias y porcentajes y se indagó asociación mediante regresión logística binaria. RESULTADOS: Completaron la encuesta 6766 adolescentes entre 11 y 19 años (16.38 ± 1.33), 61.02 % del sexo femenino. El 10 % reportó conducta suicida y entre 3 y 5 %, PSM. Los factores predictivos (χ2(8) = 387.13, p < 0.001) de la conducta suicida fueron problemas afectivos/depresión, problemas conductuales, problemas somáticos, problemas oposicionistas desafiantes y problemas de ansiedad. CONCLUSIÓN: Cinco problemas de salud mental incrementaron el riesgo de reportar conductas suicidas.

Dermoscopic Changes in Melanocytic Lesions in 368 Patients With Atypical Nevus Syndrome and Their Association With Melanoma Incidence: A Cohort Study. / Cambios en la dermatoscopia digital en lesiones melanocíticas en 368 pacientes con diagnóstico de síndrome de nevus atípicos y su asociación con el desarrollo de melanoma: estudio de cohorte.

BACKGROUND AND OBJECTIVE: Atypical nevus syndrome has been described as one of the main risk factors for melanoma. The aim of this study was to analyze dermoscopic changes observed in melanocytic lesions over a follow-up period of 5 years in patients with atypical nevus syndrome. MATERIAL AND METHODS: We conducted a retrospective follow-up study of a cohort of patients seen at a specialized skin cancer and digital body mapping clinic in Medellin, Colombia, between January 2017 and December 2022. We analyzed the dermoscopic changes observed during this period and explored their association with newly diagnosed melanoma. RESULTS: A total of 368 patients (187 women) with a median (interquartile range) age of 43 (37-51) years were included. The dermoscopic features observed at 5 years were an atypical network (222 patients, 60.3%), asymmetric globules (163, 44.2%), white-gray regression areas (105, 28.5%), lesion regression (72, 19.5%), a negative pigment network (59, 16%), asymmetric eccentric pigmentation (28, 7.6%), asymmetric projections (21, 5.7%), and asymmetric vascular patterns (8, 2.1%). Melanoma was diagnosed in 12.2% of patients during follow-up. Features significantly associated with a shorter time to melanoma onset were grayish-white areas (P <.001), asymmetric globules (P=.011), asymmetric eccentric pigmentation (P=.047), and a negative pigment network (P=.001). CONCLUSIONS: The main dermoscopic features of melanocytic lesions in patients with atypical nevus syndrome associated with progression to melanoma were grayish-white areas, asymmetric globules, asymmetric spots, and a negative pigment network.

Determinant Factors of Disease Severity for Patients With Hidradenitis Suppurativa Evaluated in a Spanish Hospital Over a 5-Year Period.

It is necessary to identify which factors or comorbidities are associated with more severe hidradenitis suppurativa, aiming to identify which patients may benefit more from early systemic treatment or a more aggressive approach. A retrospective study was conducted, including patients diagnosed with HS at the dermatology department of a Spanish hospital over a 5-year period. A total of 322 patients were included. A relationship was found between diagnostic delay, the presence of acne conglobata, pilonidal sinus, cardiovascular risk factors (hypertension, dyslipidemia, and/or diabetes mellitus) and more severe HS. No significant relationship was found between psychiatric comorbidities and the severity of the HS. The presence of perianal or truncal involvement was significantly associated with severe HS. Female sex and the presence of a family history of HS were associated with an earlier onset of the disease.

Adherence to antiretroviral therapy and factors associated with non-adherence: a cohort study at two referral services in Brazil.

This cohort study evaluated non-adherence to antiretrovirals at referral services in Pernambuco, Brazil, 2016/2017, through self-report. A generalized mixed-effects model for binary outcomewas used. We assessed 542 participants with an adherence rate of 85.50%. A greater chance of non-adherence was associated with:a low/moderate level of nicotine dependence (OR = 2.79, p = 0.00, IC = 1.44-5.41); ≥7 tablets/day (OR = 6.14, p = 0.00, IC = 3.42-11.02); LPV/r (OR = 1.49, p = 0.6, IC = 0.98-2.26), ddI (OR = 3.34, p = 0.03, IC = 1.12-9.97), ABC (OR = 4.02, p = 0.05, IC = 1.01-16.03), RAL (OR = 2.49, p = 0.01, IC = 1.32-4.70) and DTG (OR = 4.65, p = 0.01, IC = 1.42-15.16); 6-10 year seropositive diagnosis (OR = 2.17, p = 0.01, IC = 1.20-3.92) and symptoms of depression (OR = 1.55, p = 0.03, IC = 1.03-2.33). Protective factors for non-adherence weres: ≥50 years (OR = 0.67, p = 0.06, IC = 0.45-1.01), secondary/higher education (OR = 0.48, p = 0.00, IC = 0.34-0.70), embarrassment at health service (OR = 0.49, p = 0.04, IC = 0.24-0.97), good understanding of antiretrovirals (OR = 0.62, p = 0.03, IC = 0.40-0.96), adverse event (OR = 0.74, p = 0,06, IC = 0.54-1.01), use of TDF (OR = 0.62, p = 0.01, IC = 0.43-0.90), NVP (OR = 0.41, p = 0.05, IC = 0.71-1.00) and EFZ (OR = 0.48, p = 0.01, IC = 0.29-0.80) and good knowledge of HIV/AIDS/ART. (OR = 0.67, p = 0.07, IC = 0.43-1.04). Variables with stronger association were those linked to ART. Systematic use of self-report adherence is recommended for priority groups.

Prognostic risk factors in 113 patients undergoing cephalic duodenopancreatectomy for distal cholangiocarcinoma. / Factores de mal pronóstico en 113 pacientes sometidos a duodenopancreatectomía cefálica por colangiocarcinoma distal.

INTRODUCTION: Distal cholangiocarcinoma is a malignant epithelial neoplasia that affects the extrahepatic bile ducts, below the cystic duct. No relevant relationship between perioperative factors and worse long-term outcome has been proved. OBJECTIVE: To analyze the risk factors for mortality and long-term recurrence of distal cholangiocarcinoma in resected patients. MATERIALS AND METHODS: A single-center prospective database of patients operated on for distal cholangiocarcinoma between 1990 and 2021 was analyzed in order to investigate mortality and recurrence factors. RESULTS: One hundred and thirteen patients have undergone surgery, with mean actuarial survival of 100.2 (76-124) months after resection. The bivariate study did not show differences between patients depending on age or preoperative variables studied. When multivariate analysis was performed, the presence of affected adenopathy was a risk factor for long-term mortality. The presence of affected lymph nodes, tumor recurrence, and biliary fistula during the postoperative period implied worse actuarial survival when comparing the Kaplan-Meier curves. CONCLUSIONS: The presence of affected lymph nodes influence the prognosis of the disease. The occurrence of biliary fistula during postoperative cholangiocarcinoma distal could aggravate long-term outcomes, a finding that should be reaffirmed in future studies.

Case-control study of Clostridioides difficile in a rural health care area. / Estudio de casos-controles de la infección por Clostridioides difficile en un área sanitaria rural.

OBJECTIVE: To determine the risk and prognostic factors for Clostridioides difficile infection (CDI). PATIENTS AND METHODS: Prospective, case-control study with 61 cases and 64 controls, aged ≥2 years with diarrhoea, carried out in Castilla-La Mancha Health Care Area for 14 months. The diagnosis was made by immunochromatography technics (glutamate dehydrogenase and toxin A/B), confirming discordant cases by isothermal amplification. Demographic variables, comorbidities, type of acquisition, previous administration of antibiotics, antacids and immunosuppressants, and evolution were collected. The data were analysed using the chi-square test and the effect of risk and prognostic factors was quantified using an odds ratio with 95% confidence intervals. RESULTS: Hospital admission 4 weeks prior to infection, hypoalbuminemia, and previous administration of antibiotics were identified as independent risk factors for CDI. Presenting these 3 factors constitutes nearly 3-fold increase in the risk of becoming infected. A greater number of hospital admissions in the 4-12 weeks prior to CDI were found in the group of nosocomial acquisition. Although there was a greater tendency to recurrence and an unfavourable prognosis among nosocomial cases, these differences were not significant. We found that fever and hospital admission in the 4 weeks prior to infection were unfavourable prognostic factors of CDI. CONCLUSIONS: The independent risk factors for CDI were: Hospital admission in the 4 weeks prior to infection, hypoalbuminemia, and previous administration of antibiotics. Fever and hospitalisation in the previous 4 weeks were also identified as prognostic factors of unfavourable evolution.

Seroprevalence of human leptospirosis in a rural community from Tandil, Argentina. Assessment of risk factors and spatial analysis.

Leptospirosis is a neglected zoonosis that is widely distributed in the world. Although it is endemic in Argentina, prevalence remains unknown. The aims of the study were: (i) to determine the prevalence of leptospirosis in humans from a rural community in Tandil Argentina, (ii) to identify infecting Leptospira spp. serogroups, (iii) to identify factors associated with the infection, (iv) to estimate the population attributable fraction (PAF) of the risk factors and (v) to determine the spatial patterns of disease presentation and related risk factors. Blood samples from 202 participants were collected. A survey was conducted to obtain clinical and epidemiological data. Serological testing was performed by the microscopic agglutination test (MAT). Univariate and multivariate methods were applied to evaluate associations. Spatial clusters were investigated for seroprevalence and risk factors. Antibodies were found in 32.2% of participants (95% CI: 25.8-39.1). The most prevalent serogroup was Hebdomadis followed by Sejroe; Icterohaemorrhagiae; Tarassovi and Canicola. Living at lower altitudes (OR: 13.04; 95% CI: 2.60-65.32); not having access to water supply network (OR: 2.95; 95% CI: 1.30-6.69); living close to flooded streets (OR: 2.94; 95% CI: 1.14-7.69) and practicing water sports (OR: 3.12; 95% CI: 1.12-8.33) were associated with seropositivity. Factors related with housing characteristics, services and infrastructure had the higher PAF (from 17% to 81%). A spatial cluster with higher rates of positivity and of the main risk factors was determined. This work contributes useful data for specific preventive measures that should be implemented for the control of the disease.

[Risk factors for disability in patients with stroke in northeastern Mexico: A retrospective cross-sectional study]. / Factores de riesgo para discapacidad en pacientes con accidente cerebrovascular en el noreste de México: estudio retrospectivo transversal.

OBJECTIVE: To determine the risk factors associated with disability in patients who had a stroke in northeastern Mexico. DESIGN: This was an observational, retrospective, cross-sectional study. SITE: Conducted at the Family Medicine Unit No. 33 of the Mexican Institute of Social Security in Reynosa, Tamaulipas, Mexico. PARTICIPANTS: One hundred and ninety-eight males and 146 females, above 18 years old, beneficiaries of the Mexican Institute of Social Security with a diagnosis of stroke between 2018 and 2021. INTERVENTIONS: The Barthel index that assesses the degree of dependence to perform basic activities of daily living was applied to the participants and sociodemographic, biological and anthropometric variables were collected from the digital medical record. MAIN MEASURES: A univariate, correlational and ordinal logistic regression statistical analysis was performed between independent and dependent variables to obtain measures of frequency, percentages, and associated risks. RESULTS: The risk factors associated with disability were age (OR 1.03, CI 1.01-1.05), overweight (OR 1.81, CI 1.03-3.1), obesity grade I (OR 2.74, CI 1.46-5.1), obesity grade II (OR 4.38, CI 1.44-13), obesity grade III (OR 9.99, CI 2.12-47); type of stroke: ischemic (OR 4.60, CI 2.6-8) or thrombotic (OR 4.95, CI 1.57-15). The number of comorbidities was associated with disability when having one comorbidity (OR 2.80, CI 1.22-6.4), two comorbidities (OR 3.43, CI 1.37-8.5), three comorbidities (OR 2.71, CI 1.01-7.3), and with five comorbidities (OR 3.17, CI 1.01-9.9). CONCLUSIONS: The risk factors found for disability were age, overweight, obesity, and type of ischemic and thrombotic stroke. Being cared for by a relative and/or spouse reduces the probability of disability.

[Ischemic stroke and vascular risk factors in young and older adults. Community-based retrospective study (2011-2020)]. / Ictus isquémico y factores de riesgo vascular en el adulto joven y el adulto mayor. Estudio retrospectivo de base comunitaria (2011-2020).

OBJECTIVE: To analyze the presence of vascular risk factors (VRF) among young adult and older adult patients with ischemic stroke, with and without follow-up in primary care after hospital discharge. DESIGN: Observational, retrospective, multicenter study. SETTING: Primary care health centers and Hospital Verge de la Cinta, Tortosa, Spain. PARTICIPANTS: Patients with ischemic stroke of two age groups (≤55 and ≥65years) distributed in two groups (GroupA: without follow-up in primary care; and GroupB: with follow-up in primary care), between 2011-2020. MAIN MEASUREMENTS: Sociodemographic, clinical, and VRF data coded according to the International Classification of Diseases (ICD-10). Descriptive, and inferential statistics. RESULTS: Data from 2054 participants were analyzed. In the young adult group, 94.9% of the participants in groupA had between 1-2VRFs, compared to 60% in groupB. In the older adult group, 84.4% of groupA had between 1-2VRFs, compared to 43,9% of groupB. The most frequent VRFs among younger and older adult patients with ischemic stroke were hypertension and dyslipidemia in both follow-up groups. There were no records of obesity, smoking, or alcohol consumption in groupA. There was a significant association between being followed up in primary care after stroke and being a young adult and presenting between 3-4 VRFs (P<0.001). CONCLUSIONS: The results reinforce the need for continuity of care and follow-up in people with acute stroke in primary care and the need to improve the quality of registries.
