  El artículo analiza la presencia de asignaturas que atienda la gestión de residuos sólidos en los programas de educación superior en México, evidenciando una significativa carencia en la atención de esta problemática crucial en los currículos. Resalta la tendencia a ofrecer estas asignaturas de manera optativa, en lugar de incorporarlas como elementos obligatorios en la formación académica, principalmente a nivel de posgrado. El estudio sugiere una actualización y ampliación de la oferta de programas educativos de educación superior, enfatizando la importancia de abordar la problemática nacional de residuos sólidos formando profesionales e investigadores capaces de afrontar los retos que esto conlleva.

  Acute Effects of Different Volumes of High-Intensity Interval training and Continuous Aerobic Exercise in Vascular Reactivity Bailey Ramirez, Manuel Gomez, Alejandro Sanchez, Josue Reyes, Jorge De Castro, Esther Afandigeh, Angel Melenez, Daniel Conde, Alvaro N. Gurovich Endothelial dysfunction is characterized by the unbalance between vasodilatory and vasoconstrictor mechanisms. Furthermore, this is recognized as the initial step to developing cardiovascular disease. Exercise plays an important role in both cardiac rehabilitation and cardiovascular risk prevention. However, some new exercise modalities, such as high-intensity interval training (HIIT), are becoming more popular, and limited information about their effect on the endothelium is available. PURPOSE: to determine what volume of HIIT will improve more endothelial function than continuous moderate exercise intensity. METHODS: Six young apparently healthy subjects were recruited for seven laboratory visits. First visit included a graded exercise test, in which lactate levels, oxygen consumption, heart rate and RPE were collected. HIIT intensity was determine by lactate levels higher than 4.0 mmol/l. Following visits were in a randomized order in which 5 different volumes (i.e., 1 to 5 1-min repetitions with 3-min rest) of HIIT were completed and one bout of moderate-intensity exercise, lasting 30-minutes. Flow Mediated Dilation (FMD) data were obtained at three different times (Pre, Post-10-min, and Post-60-min). FMD in every time point was calculated by [(Peak brachial artery diameter – Basal brachial artery diameter)/Basal brachial artery diameter] x 100. RESULTS: No significant differences in FMD were observed between different volumes of HIIT or time (p > 0.05). Additionally, a trend to a biphasic response can be observed within the different volumes of HIIT and time (Figure). CONCLUSION: It appears that an acute session of HIIT does not promote endothelial function, regardess the HIIT volume.

  decline) and controls had stable lung function (+ 20 to - 20 mL/year). The analysis was performed in two distinct groups: (1) those who were virally suppressed for at least 6 months and (2) those with untreated HIV (from the START deferred treatment arm). We used linear mixed effects models to test the relationship between case:control status and blood concentrations of pneumoproteins (surfactant protein-D and club cell secretory protein), and biomarkers of inflammation (IL-6 and hsCRP) and coagulation (d-dimer and fibrinogen); concentrations were measured within ± 6 months of first included spirometry. We included an interaction with treatment group (untreated HIV vs viral suppression) to test if associations varied by treatment group. This analysis included 77 matched case:control pairs in the virally suppressed batch, and 42 matched case:control pairs in the untreated HIV batch (n = 238 total) who were followed for a median of 3 years. Median (IQR) CD4 + count was lowest in the controls with untreated HIV at 674 (580, 838). We found no significant associations between case:control status and pneumoprotein or biomarker concentrations in either virally suppressed or untreated PWH. In this cohort of relatively young, recently diagnosed PWH, concentrations of pneumoproteins and biomarkers of inflammation and coagulation were not associated with subsequent rapid lung function decline.Trial registration: NCT00867048 and NCT01797367.

• Biomechanical Characteristics Of The Carotid Artery During Aerobic Exercise

  Medicine & Science in Sports & Exercise · 2023-09-01

  article

  Cardiovascular disease is known as the leading cause of death, including coronary artery disease and stroke. Atherosclerosis is responsible for 9 in every 10 cases of stroke. The prevention of stroke and other cardiovascular diseases is possible through aerobic exercise (AE). However, not much is known about the biomechanical characteristics of the carotid artery during AE. PURPOSE: To estimate arterial stiffness in-vivo during submaximal cycling exercise at three different exercise intensities. METHODS: 20 apparently healthy young adults participated in two laboratory visits. First visit, subjects laid down on a medical bed, in which resting pressure, maximal/minimal artery diameter, and blood flow velocity of the carotid artery were obtained. Three recordings were obtained with a coefficient of variation (CV) of less than 5%. Compliance and stiffness were calculated from collected data. Thereafter, subjects performed a cardiopulmonary exercise test (CPET) with a graded exercise test protocol. Session two, participants performed for three submaximal intensities stages, three minutes per stage, in which the intensities were determined via lactate levels of initial CPET, low intensity: < 2.0 mmol/L. moderate intensity: 2-.0 – 4.0 mmol/L, and high intensity >4.0 mmol/L. Throughout each stage same data as resting conditions were obtained as well blood flow patterns. RESULTS: There were no differences in any of the biomechanical characteristics between resting and any of the exercise intensities (p > 0.05). However, there was a significant interaction by participants (p < 0.05). CONCLUSION: Even though the estimation of arterial stiffness per condition was not significantly different, a larger sample size, due to a significant interaction by subject, might show a different result.
