Risk factors associated with intraventricular hemorrhage in very-low-birth-weight premature infants.

PURPOSE: To analyze the association between risk factors and severe intraventricular hemorrhage (grade II-IV) in PNB under 1500 g. METHODS: Multicenter, retrospective, analytical, case-control study in PNB under 34 weeks and under 1500 g admitted to the NICU. CASE: PNB with severe intraventricular hemorrhage (grade II-IV). Logistic regression analysis was used to adjust for IVH-associated variables and odds ratios (OR). RESULTS: A total of 90 PNB files were analyzed, 45 cases and 45 controls. The highest risk factors for severe IVH were lower gestational age (OR 1.3, p < 0.001), perinatal asphyxia (OR 12, p < 0.001), Apgar < 6 at minute 1 and 5 (OR 6.3, p < 0.001). CONCLUSION: Lower gestational age, birth asphyxia, Apgar score lower of 6, and respiratory-type factors are associated with increased risk for severe IVH.

Prevalencia de tratamientos alternativos en pacientes del área de oncología en el noreste de México / Prevalence of alternative treatments in patients in the oncology area in northeastern Mexico

Resumen: Objetivo: Determinar la prevalencia del uso complementario de la herbolaria en pacientes de oncología. Materiales y Métodos: El presente estudio fue de tipo observacional, transversal, descriptivo y prolectivo. Se llevó a cabo un muestreo no probabilístico. En el estudio se incluyeron a 100 pacientes que acudieron al área de oncología del Hospital de Alta Especialidad de Ciudad Victoria "Bicentenario 2010" (HRAEV) durante el periodo del estudio y que cumplieron con los criterios de selección señalados para esta investigación. Resultados: Se realizaron 100 encuestas a pacientes oncológicos, de los cuales el 55% fue de sexo femenino. Dicha población presenta una edad promedio de 48.2 años. Respecto al origen de los pacientes, el 67% radica en Cd. Victoria. El rango de nivel educativo entre los entrevistados osciló entre preparatoria y secundaria. Los cuales pertenecen a clase media. Existe una prevalencia del 82% en el uso de tratamientos alternativos para tratar la patología, de los cuales el 76% emplea el uso de la herbolaria como coadyuvante en las diferentes enfermedades que se tratan en el hospital. Las principales plantas empleadas son: la Mariguana (Cannabis sativa) en un 45%, el 23% Noni (Morinda citrifolia) y el 12% Bardana (Arctium lappa). Conclusión: El uso de la medicina alternativa complementaria es frecuente en pacientes oncológicos, destacando la herbolaria. Por lo anterior, el comprender la dinámica de la implementación de terapias alternativas como lo es la herbolaria, permitirá comprender y guiar al paciente en su proceso de ciclos oncológicos y minimizar los efectos secundarios.

Abstract: Objective: To determine the prevalence of the complementary use of herbal medicine in oncology patients. Materials and methods: This study was observational, cross-sectional, descriptive and prolective. A non-probabilistic sampling was carried out. The study included 100 patients who attended the oncology area of the Hospital de Alta Especialidad de Ciudad Victoria "Bicentenario 2010" (HRAEV) during the study period and who met the selection criteria indicated for this research. Results: 100 surveys were carried out on cancer patients, of which 55% were female. This population has an average age of 48.2 years. Regarding the origin of the patients, 67% reside in Cd. Victoria. The range of educational level among the interviewees oscillated between high school and middle school. who belong to the middle class. There is a prevalence of 82% in the use of alternative treatments to treat the pathology, of which 76% employ the use of herbal medicine as an adjuvant in the different diseases that are treated in the hospital. The main plants used are: 45% Marijuana (Cannabis sativa), 23% Noni (Morinda citrifolia) and 12% Burdock (Arctium lappa). Conclusion: The use of complementary alternative medicine is common in cancer patients, highlighting herbal medicine. Due to the above, understanding the dynamics of the implementation of alternative therapies such as herbalism, will allow understanding and guiding the patient in their oncological cycle process and minimizing side effects. KEY WORDS: naturopathy; oncology; alternative medicine.

Prevalencia de infección de herida quirúrgica en pacientes con profilaxis antimicrobiana en cesárea programada / Prevalence of surgical wound infection in patients with antimicrobial prophylaxis in planned cesarean section

Resumen: Objetivo: Determinar la prevalencia de infecciones en la herida quirúrgica en cesáreas programadas del HRAEV. Materiales y método: Estudio retrospectivo, descriptivo, observacional tipo corte transversal para determinar la prevalencia de IHQ en pacientes llevadas a cesárea programada con profilaxis antibiótica en HRAEV. Resultados: Se evaluaron 185 expedientes de pacientes sometidas a cesárea programada, con edad entre 28 a 37 años (48.1%) con un peso promedio 81 kg (DE=10.1) con un índice de masa corporal (IMC) promedio de 30 (DE=4.24) es decir un IMC entre 25.76 a 34.24. De ellas, 4 pacientes (2.16%) presentaron infección de herida quirúrgica durante cesárea programada, las cuales recibieron ceftriaxona como PA mayor a 120 minutos previo a la incisión de la piel, estos pacientes se clasifican como ASA II y tenían un IMC superior a 30 kg/m2 y sin comorbilidades registradas. El tiempo de profilaxis antibiótica más frecuente en las pacientes llevadas a cesárea programada fue >120 minutos (34.08%) y se administró ceftriaxona en el 84.86% de la población que en su mayoría es ASA II (97.83%). El 100% de las heridas fueron superficiales. Conclusiones: En el presente estudio se encontró que la prevalencia de IHQ en cesáreas programadas en HRAEV fue de 2.16%, cifra que se encuentra por debajo de la prevalencia a nivel mundial, dado a que las pacientes seleccionadas no contaban con algunos de los factores de riesgo añadidos que aumentaran el riesgo de IHQ en comparación con otros estudios.

Abstract: Objective: To determine the prevalence of surgical wound infections in scheduled HRAEV cesarean sections. Materials and method: Retrospective, descriptive, observational cross-sectional study to determine the prevalence of IHC in patients undergoing scheduled cesarean section with antibiotic prophylaxis in HRAEV. Results: 185 records of patients undergoing scheduled cesarean section were evaluated, aged between 28 to 37 years (48.1%) with an average weight of 81 kg (SD = 10.1) with an average body mass index (BMI) of 30 (SD = 4.24) that is, a BMI between 25.76 and 34.24. Of these, 4 patients (2.16%) presented surgical wound infection during scheduled cesarean section, who received ceftriaxone as PA greater than 120 minutes prior to skin incision, these patients are classified as ASA II and had a BMI greater than 30 kg/m2 and without recorded comorbidities. The most frequent antibiotic prophylaxis time in patients undergoing scheduled cesarean section was >120 minutes (34.08%) and ceftriaxone was administered in 84.86% of the population, which is mostly ASA II (97.83%). 100% of the wounds were superficial. Conclusions: In the present study, it was found that the prevalence of IHC in cesarean sections scheduled in HRAEV was 2.16%, a figure that is below the worldwide prevalence, given that the selected patients did not have some of the risk factors. added risk that increased the risk of SSI compared to other studies.

In vitro evaluation of the antagonistic activity of native strains of Trichoderma spp. against Fusarium spp.

Five samples of agricultural soil and five samples of Aloe barbadensis (P. Mill., 1768) plants with symptoms of wilt and root necrosis were collected in five localities of the state of Tamaulipas, México. The aims of this study were the morphological identification, molecular identification and in vitro evaluation of the antagonistic activity of Trichoderma spp. on Fusarium spp. Four strains of Trichoderma asperellum, one strain of Trichoderma harzianum and five strains of Fusarium oxysporum were identified by morphological and molecular methods. The evaluation of the antagonistic activity of T. harzianum isolate (TP) showed the highest inhibition in Fusarium spp. (78.80%). The evaluation of the antagonistic activity of Trichoderma spp. extracts in Fusarium spp. did not show significant differences between treatments (P ≤ 0.05), with Trichoderma growth percentages that oscillated between 81.08 and 94.38%. The native isolate of T. harzianum (TP) showed significant competitive capability against the mycelial growth of F. oxysporum. Trichoderma species are promising agents of biological control in the central area of the State Tamaulipas, Mexico.
