Metabolic syndrome (MS) with mixed dyslipidemia and prostate cancer (PC) are relevant health problems among Mexican men. However, there is no information regarding the association between MS and PC for this population. To evaluate this association in a population case-control study in Mexico City. We analyzed the information from 394 incident PC-cases and 793 population age-matched (± 5 years) controls, identified in Mexico City (2011–2014). For cases, Gleason score at diagnosis was available. We defined MS history based on the self-report of hypertension, hypercholesterolemia, hypertriglyceridemia, and diabetes; obesity was evaluated using weight-change trajectories throughout life. In addition, the four MS-typologies described for Mexican population were used. The association between MS with PC and histological PC differentiation was evaluated using independent multivariate logistic regression models. MS history was associated with a high PC probability (OR 1.94; 95% CI 1.37–2.75). Lipid alterations, arterial hypertension, and a marked weight increase throughout life were associated with increased PC probability; however, only the marked weight increase was associated with more poorly differentiated PC (Gleason ≥8) (OR 2.79; 95% CI 1.50–5.17). Like other populations, in this Mexican study, MS and some of its components were identified as potential PC risk factors. MS-lipid alteration typology seems to be relevant; however, the novelty of this approach together with the retrospective nature of this study, indicate that a prospective evaluation of the MS typologies and PC association must be performed.

In this paper, the thermal and ventilation potential of a geothermal Earth-to-Air Heat exchanger (EAHE) is studied for six weather in Mexico. The cities for the study and their climate were Villahermosa (hot-humid), Merida (hot-sub humid), Monterrey (dry), Juarez City (very dry), Zacualtipan-Hidalgo (warm-humid) and Mexico City (warm-sub-humid). The thermal behavior of the EAHE was modeled numerically for the corresponding warmest and coldest days of the year for each city and three values of Reynolds number. The 24 hrs simulations were carried out with an in-house code using data every 10 minutes. To get the results, 5,184 computational runs were necessary. The results showed that the EAHE has poor ventilation potential for climates with high levels of humidity such as Villahermosa, while for cities with low levels of humidity such as Chihuahua, the ventilation potential increases significantly, the rest of the cities fall in between. As for its application in Mexico, the results show that the EAHE is highly recommended for dry climates such as at the north of the country and not recommended for humid climates such as at the south and south-east of the country.

The thermal analysis of a Room (R) coupled with a Double Glazing Window (DGW) with/without solar control film (SCF) for warm and cold climate conditions of Mexico City is presented. The right vertical surface of the room is considered partially adiabatic and with a DGW. The DGW consists of two vertical semitransparent walls: glazing-1 facing the room, and glazing-2 facing the external environment; there is a SCF attached to glazing-1 for cold climate condition, or glazing-2 for warm climate condition. During one day, the hourly simulations of the R-DGW were done in an in-house code based on the finite volume method. To carry out the thermal analysis of the R-DGW, three cases were defined: Case C1 corresponds to the R-DGW without SCF; Case C2 and C3 correspond to the R-DGW with SCF for warm and cold climate condition, respectively. For warm climate condition the use of a SCF is highly recommended, since Case 2 reduces the amount of energy gained in ≈67.7% compared to Case 1. When using the SCF on the R-DGW for cold climate condition case C3, the average temperature inside of the room is similar to case C1. [ABSTRACT FROM AUTHOR]
