This investigation reports on the biological control of Sphenarium purpurascens by using different concentrations of conidia from a native strain of Beauveria bassiana (MABb1) isolated in Puebla, Mexico under laboratory and in situ conditions. Formulations containing this native strain combined with two mesoporous materials (diatomaceous earth “D” and zeolite “Z”) were assayed in order to determine their effect on the mortality of the grasshopper. Concentrations of 3.67 × 108 to 10.30 × 108 conidia mL−1 caused a substantial mortality rate in the fourth-instar nymphs and adults of S. purpurascens. The observed mortality was directly proportional to the concentration of conidia. Under controlled conditions, the highest specific death rate K(d−1) was 0.78 for the formulation containing Z + D + MABb1 at 72 h post-infection. The formulations of D + MABb1 and Z + D + MABb1 caused a noticeable decrease in the population of grasshoppers in the experimental plots with statistical significant differences (α < 0.05). Interestingly, an increase in the mortality of S purpurascens occurred in July, August and September 2017 when the highest incidence of the grasshopper was recorded. Remarkably, the treatment based on Z + D + MABb1, produced an improvement in the yields of experimental maize plots (7847.4 ± 0.70 Kg ha−1) in comparison to control plots (4453.9 ± 0.50 Kg ha−1). These favorable consequences are reported for the first time in corn crops from Mexico.

Maternal high-sweetener diet, such as sucrose, has been associated with an increased risk of metabolic and cognitive-related diseases in the offspring. This study was performed to determine the effect of maternal sweetener intake during gestation and lactation on learning and memory in adult female offspring rats. Twenty-eight female pups from dams fed standard diet (Control-C, n = 10), high-sucrose diet (HS-C, n = 6), and high-honey diet (Ho-C, n = 12) were fed standard diet after weaning and body weight and food intake were recorded once a week for 19 weeks. Learning and memory tests were conducted at week 14 (Y-maze) and 18 (Barnes maze). We found that birth weight of Control-C group was greater than the Ho-C (P < .001). Blood glucose levels of the HS-C group were significantly higher than the Control-C and Ho-C groups. Control-C pups recognized the novel arm of the Y-maze compared with HS-C and Ho-C groups (P < .01). Also, offspring of the HS-C group showed deficient performance in the Barnes test when compared with the Control-C and Ho-C groups (P < .05). These results suggest that dams fed a high-sucrose diet during gestation and lactation favor high-glucose levels and deficient long-term memory performance in adult female offspring rats.

Correct nutrition is important for keeping good health; to attain that, the diet has to include vegetables such as quelites. The objective of this study was to determine the glycemic index (GI) and glycemic load (GL) of rice and a tamal prepared with and without two species of quelites: “alache” (Anoda cristata) and “chaya” (Cnidoscolus aconitifolius). The GI was measured in 10 healthy subjects, 7 women and 3 men, with the following mean metrics: age, 23 years old; body weight, 61.3 kg; height, 1.65 m; body mass index, 22.7 kg/m2; and basal glycemia, 77.4 mg/dL. Capillary blood samples were collected within 2 h after the meal. White rice (rice with no quelites) had a GI of 75.35 ± 15.6 and a GL of 36.17 ± 7.8; rice with alache had a GI of 33.74 ± 5.85 and a GL 33.74 ± 1.85. White tamal had a GI of 57.33 ± 10.23 and a GC of 26.65 ± 5.12; tamal with chaya had a GI of 46.73 ± 22.1 and a GL of 23.36 ± 11. The GI and GL values recorded for the combination of quelites with rice and tamal confirmed that quelites could be a good alternative for healthy diets.

Background/Aims: Colorectal cancer (CRC) is a public health problem. In Mexico, there have been no recent studies conducted on survival in terms of this pathology or on the influence of prognostic factors. The study aims to determine the probability of survival in patients with CRC presence of low levels of schooling and a rural population, adjusted for clinical stage and type of treatment. Methods: A retrospective study was conducted in a cohort of 305 patients with CRC treated at State Cancer Center, located in Veracruz-Mexico; the follow-up period of 60 months (2012-2016). The survival probability was calculated using the Kaplan-Meier estimator and the log-rank test with 95% confidence intervals (CIs). Prognostic factors were determined using hazard ratio (HR) multivariate Cox regression analysis. Results: Overall survival was 40% at 60 months. Subjects in the age group ≥65 years had a low survival rate of 28% (P=0.026) and an advanced clinical stage of 22% (P<0.001). Of the patients with bone metastasis, none survived longer than 5 years (P=0.008). With respect to the unfavorable prognostic factors identified in the multivariate analysis, a decreased level of schooling was associated with an HR of 7.6 (95% CI, 1.1-54.7), advanced clinical stage was associated with an HR of 2.1 (95% CI, 1.2-4.0), and the presence of metastasis had an HR of 1.8 (95% CI, 1.1-2.9). Conclusions: Poor prognostic factors include an advanced clinical stage, the presence of metastasis and a low level of schooling. These findings confirm the importance of screening for early diagnosis, diminishing the barriers to accessing treatment and prospectively monitoring the population. (Intest Res 2020;18:315-324)

Background/Aims To evaluate the effectiveness of pantoprazole magnesium (pantoprazole-Mg) 40 mg in the relief of esophageal and extra- esophageal symptoms of gastroesophageal reflux disease (GERD), particularly night-time symptoms. Methods Patients (aged 18-50 years) with 3-month history of heartburn and/or acid regurgitation plus at least one other symptom in the last week were enrolled in a nationwide, prospective and observational study in Mexico. Patients received pantoprazole-Mg 40 mg once daily during 4 weeks. Symptoms were assessed through a physician-administered structured interview and the patient- completed ReQuest in PracticeTM questionnaire. Night-time GERD was defined as arousal from sleep during the night due to GERD-associated symptoms. Results Out of 4,343 patients included at basal visit, 3,665 were considered for the effectiveness per protocol analysis. At baseline, patients had a median of 8 GERD related symptoms. Patients with night-time GERD symptoms (42.7%) were more likely to have extra-esophageal symptoms (P < 0.001) than other GERD patients. Pantoprazole-Mg 40 mg once daily for 4 weeks improved a broad range of GERD-associated symptoms from baseline (80% reduction on physicians assessments; 68-77% reduction on ReQuest in PracticeTM dimensions), including both day- and night-time GERD symptoms; improvements were the greatest for extra-esophageal symptoms in patients with night-time symptoms. Pantoprazole-Mg was well tolerated. Conclusions Pantoprazole-Mg 40 mg significantly improved a broad range of esophageal and extra-esophageal GERD related symptoms including sleep disturbances, as well as well-being, in patients with daytime or night-time GERD, making it a good option for patients with GERD, especially when extra-esophageal and night-time symptoms are present.

Martín Bedolla-Barajas,Tonatiuh Ramses Bedolla-Pulido,Alan Salvador Camacho-Peña,Estefanía González-García,Jaime Morales-Romero 대한천식알레르기학회 2014 Allergy, Asthma & Immunology Research Vol.6 No.6

Purpose: There is limited epidemiological evidence of food hypersensitivity (FH) in the adult population. We aimed to determine the prevalence of FH in Mexican adults, their clinical features and to establish common food involved in its appearance. Methods: We designed a cross-sectional study using a fixed quota sampling; 1,126 subjects answered a structured survey to gather information related to FH. Results: The prevalence of FH in adults was 16.7% (95% CI, 14.5% to 18.8%), without statistical significant differences related to gender (women, 17.5% and men, 15.9%) or residential location. The most common clinical manifestations in adults with FH were oral allergy syndrome (70 of 1,126) and urticaria (55 of 1,126). According to category, fruits and vegetables were the most frequent foods to trigger FH (6.12%) and were individually related to shrimp (4.0%), and cow milk (1.5%). Adults under age 25 had a higher frequency of FH (OR, 1.39; 95% CI, 1.01 to 1.91, P <0.001). Personal history of any atopic disease was significantly associated with FH (P <0.0001). Conclusions: The prevalence of FH is relatively high in Mexican adults, and FH is significantly associated with atopic diseases.
