AIM To evaluate the rate of adverse events(AEs) during consecutive gastric and duodenal polypectomies in several Spanish centers. METHODS Polypectomies of protruded gastric or duodenal polyps ≥ 5 mm using hot snare were prospectively included. Prophylactic measures of hemorrhage were allowed in predefined cases. AEs were defined and graded according to the lexicon recommended by the American Society for Gastrointestinal Endoscopy. Patients were followed for 48 h, one week and 1 mo after theprocedure. RESULTS308 patients were included and a single polypectomy was performed in 205. Only 36(11.7%) were on prior anticoagulant therapy. Mean polyp size was 15 ± 8.9 mm(5-60) and in 294 cases(95.4%) were located in the stomach. Hemorrhage prophylaxis was performed in 219(71.1%) patients. Nine patients presented AEs(2.9%), and 6 of them were bleeding(n = 6, 1.9%)(in 5 out of 6 AE, different types of endoscopic treatment were performed). Other 24 hemorrhagic episodes could be managed without any change in the outcome of the endoscopy and, consequently, were considered incidents. We did not find any independent risk factor of *** Gastroduodenal polypectomy using prophylactic measures has a rate of AEs small enough to consider this procedure a safe and effective method for polyp resection independently of the polyp size and location.

Let （Ω, ∑） be a measurable space and mo ： E→ Xo and m1 ： E → X1 be positive vector measures with values in the Banach KSthe function spaces Xo and X1. If 0 〈 a 〈 1, we define a X01-ax1a new vector measure [m0, m]a with values in the Calderdn lattice interpolation space and we analyze the space of integrable functions with respect to measure [m0, m1]a in order to prove suitable extensions of the classical Stein Weiss formulas that hold for the complex interpolation of LP-spaces. Since each p-convex order continuous Kothe function space with weak order unit can be represented as a space of p-integrable functions with respect to a vector measure, we provide in this way a technique to obtain representations of the corresponding complex interpolation spaces. As applications, we provide a Riesz-Thorin theorem for spaces of p-integrable functions with respect to vector measures and a formula for representing the interpolation of the injective tensor product of such spaces.

作者： Marina Medina Corrales Blanca de la Cruz Torres Alberto Garrido Esquivel Marco antonio Garrido Salazar José naranjo Orellana Pablo de Olavide University Seville Spain Sports Organisation Faculty Autonomous University of Nuevo León Monterrey Mexico University of Seville Seville Spain

This study analyzed Heart Rate Variability in a large sample of active young subjects within a narrow age range (18 to 25), using time and frequency domain methods and a Poincaré plot. Heart rate was recorded (beat to beat) for 30 minutes at rest in 200 healthy subjects divided into 4 groups: 50 sportsmen (20.54 ± 1.52 years);50 active men (21.22 ± 1.31 years);50 sportswomen (20.10 ± 1.87 years) and 50 active women (20.92 ± 1.87 years). Significant differences were found for most parameters between athletes and active subjects (male and female) but not between genders. Percentile distributions were provided for all parameters (according to gender and physical activity level) to be used as references in future researches.

Open Journal of Pediatrics 2012年第2期2卷 111-117页

Adverse drug reactions (ADRs) are an important clinical problem and contribute significantly to mortality and morbidity. Scant data on the safety of drug use in children are usually available at the time of marketing authorization, due to the limited number of trials performed in the paediatric population. Few studies monitored the incidence of ADRs in Italian hospitalized children, that cannot be compared for methodological reasons. A 6-month prospective observational study was, therefore, conducted on the paediatric wards of five hospitals in the Campania Region, Italy. Data were collected on all patients admitted to the wards during the study period through a structured questionnaire administered to the mothers and through a hospital chart review. Of the 752 patients enrolled, 86.2% were exposed to one or more drugs during hospitalization. The therapeutic class most prescribed was systemic antibacterial agents (47%). Six ADRs occurred during hospitalization (incidence 0.9%;95% CI 0.2% - 1.7%). In addition, one child was admitted to a hospital for an ADR. Five out of seven ADRs occurred in girls. The skin was the most affected organ. The medications implicated were amoxicillin, acyclovir, ibuprofen, ceftriaxone, paracetamol, and ranitidine. According to the naranjo probability criteria, six ADRs were probably, and one possibly, related to the suspected drug. In conclusion, this study reveals that ADRs may be under-reported in children hospitalized in the Campania Region. Consequently, healthcare personnel should be alert to the possibility of ADRs. More accurate reporting of ADRs in children would result in safer use of drugs in such patients.

Introduction: The standard treatment for complex wound care is autografting. The advent of dermal substitutes has provided a novel tool for the preparation of the bed to be grafted. However, most types of dermal matrices require the application of a skin graft a second time. Currently, other strategies have been developed to improve the vascularization process, such as negative pressure wound therapy (NPWT), which has been reported to reduce the time required for vascular growth and dermal matrix integration and thus achieve a shorter waiting period for autologous graft application. The present study aims to evaluate the effectiveness and safety of dermal matrix management associated with NPWT in the treatment of complex wounds. Methods: Seven patients with a diagnosis of complex wounds were enrolled in this study between July 1, 2015, and June 31, 2016. After debridement and having an adequate wound bed, patients who met the criteria for the application of combined therapy were treated with dermal substitutes and a negative pressure system. The percentage of graft integration into the wound bed, complications, length of hospital stay, and duration of therapy were analyzed. Results: The mean age was 42.5 ± 16 (39 - 54) years old;three women and four men were included in the study. The approximate size of skin loss was 120.7 ± 75 cm2 (25 - 250 cm2). The combined therapy of dermal matrix plus NPWT was instituted in all cases for a period of 14 days. There were no complications, with 100% graft integration in 6 of 7 cases. Patients were discharged after a mean hospital stay of 5.4 days. Conclusions: This study demonstrates that the utilization of combined dermal matrix plus NPWT therapy can be performed safely and effectively in patients with complex wounds with low complication rates and a short hospital stay.

Modern Plastic Surgery 2023年第4期13卷 118-125页

作者： Alfredo Chama naranjo Cuahutémoc Márquez Espriella Alberto Ignacio Cahuana Quispe Barbosa Villarreal Fernando Ana Priscila Campollo López Mauricio Gutiérrez Álvarez Carlos Emiliano García Córdova Jesús Ricardo García Corral Cuervo Vergara Marco antonio Jorge Luis Rosales Becerra Dávila Díaz rodrigo Edgar Alan Guillen Martínez Marín Canto Miguel Eduardo Luis Arturo Herrera Lozano Ochoa Contreras Erick Cesar Martinez Villalobos Claudia Nallely Cruz Soto Randall Camacho rodriguez Hayah Ricardo Alberto Pulido López Edwing Michel Jaimes Durán Department of Plastic and Restrictive Surgery Hospital Central Sur de Alta Especialidad Pemex Mexico City Mexico

Background: In clinical practice, acute and chronic wounds continue to be a challenge. Unfortunately, wound care is often inadequate or inappropriate. The implementation of wound clinics involving an interdisciplinary team for wound care and treatment yields favorable clinical outcomes as well as a reduction in economic expenses due to a higher rate of healing, a decrease in hospital stays, and a reduction in the number of readmissions. The establishment of wound clinics enhances the utilization of diagnostic, preventive, and therapeutic resources, improving the quality of life of patients and facilitating their reintegration into their normal lives. The objective is solely to describe the importance of wound clinics in the medical profession. Methods: A retrospective literature search was conducted to include articles no more than 10 years old that reported measures or results of the study in order to perform a literature review and describe the importance of wound clinics in medical practice. Results: A total of 7 articles were obtained with the inclusion criteria, the most recent being from the year 2023 and the oldest from 2013. Conclusion: An important area for improvement in the healthcare industry is the management and treatment of complex wounds. The establishment of wound clinics offers comprehensive and specialized care for both acute and chronic complex wounds with the goal of enhancing secondary illness patients’ prevention, treatment, and rehabilitation.
