ABSTRACT
Resumen OBJETIVO: Evaluar la prevalencia de obesidad en el área de influencia del Hospital Universitario Infanta Leonor y analizar los desenlaces obstétricos y perinatales de embarazadas obesas. MATERIALES Y MÉTODOS: Estudio observacional, transversal y retrospectivo efectuado con base en los datos de partos atendidos en el año 2019 en el Hospital Universitario Infanta Leonor y asentados en las historias clínicas. Se evaluaron y determinaron la prevalencia de obesidad, las variables maternas y el desenlace perinatal en embarazadas con obesidad. RESULTADOS: Se analizaron 428 embarazadas, con obesidad, de 2048 partos atendidos. La prevalencia de obesidad fue 21.59%. La edad materna fue 32 años y 39.10% eran migrantes; el índice de masa corporal (IMC) medio fue 33.61 kg/m2; 33.18% eran primíparas; 14.12% recibieron algún tratamiento y 18.63% seguimiento endocrinológico. Las semanas de embarazo al parto fueron 39; 43.93% de los partos se indujeron. La tasa de cesáreas fue 26.17% y en el 51.45% hubo complicaciones. El peso medio de los recién nacidos fue 3345.9 g. La mediana del Apgar al primer minuto fue 9 y 10 a los 5. El 16.24% de los recién nacidos tuvo pH en sangre de cordón ≤ 7.20; 1.96% de los recién nacidos ingresó a cuidados intensivos y 0.93% fue la tasa de muerte fetal. CONCLUSIONES: La prevalencia de obesidad fue superior a la media nacional. Factores como la migración y la multiparidad se asociaron con mayor IMC, y éste con más complicaciones (ingreso a cuidados intensivos y muerte fetal anteparto). La obesidad se asoció con mayor tasa de inducción de parto, cesáreas, desgarros perineales, peso fetal y menor pH al nacimiento.
Abstract OBJECTIVE: To evaluate the prevalence of obesity in the healthcare area of Hospital Universitario Infanta Leonor and analyze the obstetric and perinatal outcomes of obese patients. MATERIALS AND METHODS: This is a retrospective transversal observational study based on data from births in Hospital Universitario Infanta Leonor during 2019. 2048 clinical records were evaluated in order to determine prevalence of obesity, as well as maternal and perinatal outcomes variables in pregnant women with obesity. RESULTS: A total of 428 pregnant women with obesity were analyzed out of 2048 deliveries attended. The prevalence of obesity was 21.59%. Maternal age was 32 years; 39.10% of the patients were migrants; the mean BMI was 33.61 kg/m2; 33.18% were primiparous; 14.2% received any pharmacological treatment and 18.63% had endocrinological follow-up. Gestational age at labour was 39 weeks; 43.93% of deliveries were induced; caesarean delivery rate was 26.17% and 51.45% presented complications. Newborn's mean weight was 3345.9 g. The 1-minute Apgar score median was 9 and the 5-minute Apgar score was 10; 16.24% of newborns had cord pH≤7.20; 1.96% ICU admission and 0.93% of fetal death. CONCLUSIONS: The prevalence of obesity in pregnant women in the Hospital Universitario Infanta Leonor healthcare area was higher than the national mean. Factors such as migration and multiparity are associated with higher BMI, which leads to an increased risk of complications, especially ICU admission and antepartum fetal death. Obesity is associated with a higher rate of labour induction, caesarean delivery, tears, higher neonatal weight and lower pH.
ABSTRACT
Abstract Background Febrile neutropenia (FN) is a common complication in children who receive chemotherapy for cancer. Objective The objective of this study was to evaluate the clinical efficacy of the continuous versus intermittent infusion of piperacillin/tazobactam (TZP) in febrile neutropenic pediatric patients. Methods This is a non-blinded randomized controlled clinical trial. Eligible group consisted of hemato-oncological patients with FN who were candidates to receive TZP. Patients were randomized to one of two groups: Group 1 received antibiotic treatment through intravenous intermittent infusion of TZP 300 mg/kg/day based on piperacillin, divided into four doses, not exceeding 16 g/day; Group 2 received an initial TZP loading dose of 75 mg/kg infusion over 30 min, and then a continuous infusion of TZP 300 mg/kg/day through central line with pump over 24 h. Results There were 176 episodes that could be assessed, 100 in Group 1 and 76 in Group 2. There was no statistically significant difference in treatment failure in the experimental group (continuous infusion) compared with the intermittent group, 21% versus 13% (p = 0.15). The increase in the absolute risk reduction was 0.08% (95% confidence interval 0.12-0.30), and the number needed to treat was 12.4. One patient in each group died. Conclusions There were no differences in fever resolution, clinical cure rate, or mortality when comparing the continuous with the intermittent TZP infusion.

The chemical composition of the essential oil and carotenoid content of the parasitic plant Cuscuta mitraeformis are described for the first time. The essential oil was analyzed by GC-FID and GC-MS revealing nonanal (24.6%) as the main constituent followed by thymol (16.5%) and eugenol (7.5%). The total carotenoid content (130 mg 100 g-1 FW) was determined by HPLC-DAD. The carotenoid fraction contained ß-carotene (76.4 mg 100 g-1 FW) and lutein (18.9 mg 100 g-1 FW) as the most abundant compounds. A weak antioxidant activity was observed by the essential oil against DPPH radical (IC50, 1.4 mg mL-1), whereas a strong antioxidant activity was determined for the carotenoid fraction (IC50, 60.1 µg mL-1). The essential oil inhibited the growth of Clavibacter michiganensis, Pseudomonas syringae pv. tomato and Erwinia carotovora with minimum inhibitory concentrations of 122.5, 184.5, 234.2 µg mL-1, respectively.

BACKGROUND: Karwinskia humboldtiana (Kh) is a poisonous plant of the rhamnacea family. To elucidate some of the subcellular effects of Kh toxicity, membrane fluidity and ATPase activities as hydrolytic and as proton-pumping activity were assessed in rat liver submitochondrial particles. Rats were randomly assigned into control non-treated group and groups that received 1,1.5 and 2 g/Kg body weight of dry powder of Kh fruit, respectively. Rats were euthanized at day 1 and 7 after treatment. RESULTS: Rats under Kh treatment at all dose levels tested, does not developed any neurologic symptoms. However, we detected alterations in membrane fluidity and ATPase activity. Lower dose of Kh on day 1 after treatment induced higher mitochondrial membrane fluidity than control group. This change was strongly correlated with increased ATPase activity and pH gradient driven by ATP hydrolysis. On the other hand, membrane fluidity was hardly affected on day 7 after treatment with Kh. Surprisingly, the pH gradient driven by ATPase activity was significantly higher than controls despite an diminution of the hydrolytic activity of ATPase. CONCLUSIONS: The changes in ATPase activity and pH gradient driven by ATPase activity suggest an adaptive condition whereby the fluidity of the membrane is altered.

We report the results of in vitro anti-lipase and antioxidant assays using crude ethanolic extracts from 30 plants grown in Oaxaca, México. Anti-lipase tests were performed by using porcine pancreatic lipase (PPL) [EC 3.1.1.3] from Affymetrix/USB. The extracts of Solanum erianthum, Salvia microphylla, Brungmansia suaveolens and Cuphea aequipetala showed up to 60% PPL inhibition. The effect of these extracts on the kinetic parameters of PPL (Km= 0.36 mM, and Vmax=0.085 mM min -1) revealed that the alcoholic preparations of S. erianthum and C. aequipetala engendered a non-competitive inhibition (Vmax=0.055 mM min -1; Vmax= 0.053 mM min -1), whereas those of S. microphylla and B. suaveolens produced a mixed inhibition (Km= 0.567 mM, Vmax=0.051 mM min _1; Km=0.643 mM, Vmax= 0.042 mM min ¹). In addition to these findings, seven extracts from different plants were able to inhibit PPL in the range of 30-50%. Antioxidant tests against 2,2-Diphenyl-1-picryl hydrazyl (DPPH) confirmed that Arctostaphylos pungens, Gnaphalium roseum, Crotalaria pumila, Cuphea aequipetala, Rhus chondroloma, and Satureja laevigata possess relevant antioxidant activity (IC(5)0=50-80 μg mL¹). The general composition of the most effective ethanolic extracts was obtained in order to confirm their known chemistry reported by previous works. Comprehensive chemical analysis of the ethanolic extracts and their poisoning effects suggests that S. microphylla, C. aequipetala and A. pungens could be considered as the best sources with both desired properties.

Con el objeto de evaluar la utilidad de tres distintos esquemas terapéuticos en la faringoamigdalitis aguda (FAA) no purulenta, se realizó un ensayo clínico controlado que comparó tres grupos de 30 pacientes cada uno: grupo A con tratamiento sintomático, grupo B tratado con penicilina procaínica por siete días más medicamentos sintomáticos, grupo C tratado con penicilina procaínica por dos días y con penicilina benzatínica por dos días y con penicilina benzatínica al tercer día, y sintomáticos. Este estudio nos permitió observar que no existieron diferencias estadísticamente significativas cuando comparamos los tres grupos, p> 0.6, p> 0.6 y p> 1, respectivamente. Se propone el tratamiento sintomático en la FAA para brindar mayor beneficio terapéutico y evitar el uso indiscriminado de antibióticos en la consulta de medicina familiar
