The article talks about the work of Las Patronas, a group of women in Mexico who provide food, lodging, and guidance to Central American migrants passing through the railway in Guadalupe la Patrona, Veracruz. Over the course of 28 years, they have supported migrant caravans and Central American mothers searching for their missing relatives. The article also highlights the importance of civil society in the migration issue and mentions different forms of migration, as well as the need for humanitarian aid along migration routes. Despite the challenges, the work of Las Patronas has been recognized as important in defending the human rights of migrants. [Extracted from the article]

The Cerro Marcelinos (CM) and Cerro Colorado (CC) plutons are part of the Candela-Monclova intrusive belt (NE Mexico), which is mid-Eocene in age (43-35 Ma). It intrudes into the Sabinas Basin, primarily made up of limestones, of Lower and Upper Cretaceous age. Around several intrusions, including the CM and CC plutons, mineralizations are known. However, how much hidden mineralizations would occur is not known. Trends within the plutons and in contact aureoles are also poorly described at present. Therefore, we provide here in situ magnetic susceptibility (MS) and gamma ray spectrometry (GS) data along two composite transects, one in each pluton, to delineate such potential trends. The data show variations of 0.003 × 10-3 SI and 104 × 10-3 in MS and of 7.1 nGy/h and 196 nGy/h in GS with a clear relation to rock type and amount of metasomatism. The radioactive contents in the outcrops of contact metamorphic rocks indicate a contact metasomatism with differing degrees of alteration during emplacement of the plutons. The host limestones have magnetic minerals incorporated during the intrusion process. MS and GS indicate an increase in the degree of acidity towards the center of both plutons, possibly associated with the later stages of the magmatic differentiation process. The MS could divide the igneous rocks into two groups, weakly magnetic (group 1 with MS = 3 × 10-3 SI) and strongly magnetic (group 2 with MS > 3 × 10-3 SI), associated with the magnetite and ilmenite series, respectively. These classes provide useful information regarding the internal magnetic zoning in the plutons, which can be associated with mineralizations of mainly Au and Cu. Mainly, the magnetite series (group 2) delimited more perspective zones for mineral exploration. This zoning in MS could guide future mineral exploration in both plutons. [ABSTRACT FROM AUTHOR]

Electrical burn injuries are one of the most severe forms of trauma. This study aims to investigate the infection complications in electrical burn patients in a referral hospital in Mexico City. A longitudinal retrospective study was conducted, involving electrical burn patients admitted from April 2011 to December 2016. Demographic and clinical data including type of electric burns, infection complications, and mortality was sought. Data were collected at admission and daily until discharge. Number and type of infections and microorganism isolations were sought. Risk factors for death were analyzed. A total of 111 patients were included, of which 96.4% were males, mean age of 31.6±16.22, most injuries were high voltage associated. The total body surface area average was 27.8% ± 19.63. The overall infection rate was 72.9 cases per 100 patients. Mortality was observed in 4 (3.6%) patients. About 59.1% (443/749) had growth for Gram-negative bacteria. Multidrug-resistant Pseudomonas aeruginosa was the most frequent microorganism isolated. Fungi were present in 4.9% of cases. Electrical burn injuries occurred in young males in our study. Infection was frequent, most of them caused by Gram-negative rods with an important rate of antimicrobial resistance; however, an important microbial diversity was present. [ABSTRACT FROM AUTHOR]

Objective: Determine the effectiveness of endoscopy in cochlear implantation as compared to microscopy., Method: Study comparing microscopy and endoscopy in cochlear implant placement in 34 patients (23 endoscopic implants and 20 implants via microscopy), between 2014 and 2019, at the Centro Medico Naval, Mexico City. The study was performed under informed consent and according to the Council for International Organizations of Medical Sciences (CIOMS)., Results: Of the 34 patients, 12 were children or adolescents and 22 were adults. The visualization of the round window classified via microscopy per St. Thomas Hospital's classification showed that type IIB prevailed in 30.2% of patients, and type III in 41.9%, and when using the endoscope, the round window was observed in full in 82.6% of patients (type I), and type IIA was only observed in 17.4% (four patients). The number of attempts made to place the cochlear implant was greater with the microscope. The time to insertion of the electrode was 1.6 minutes. No differences were observed (p > 0.05) in the number of inpatient days. Cochleostomy was more frequent when using the microscope., Conclusions: Endoscopy is an effective resource in cochlear implantation for posterior tympanotomy, with no complications observed, offering greater safety in inserting the electrode through the round window., (Copyright: © 2023 Permanyer.)
