BACKGROUND: Entamoeba histolytica, an intestinal parasitic protozoan that usually lives and multiplies within the human gut, is the causative agent of amoebiasis. To date, de novo glutathione biosynthesis and its associated enzymes have not been identified in the parasite. Cysteine has been proposed to be the main intracellular thiol. METHODS: Using bioinformatics tools to search for glutaredoxin homologs in the E. histolytica genome database, we identified a coding sequence for a putative Grx-like small protein (EhGLSP) in the E...

The European Radiation Dosimetry Group has carried out several different types of intercomparison (IC) exercises in the past that qualify as proficiency tests for different dosimetry systems and types of radiation. The first neutron dosemeter IC was held in 2012 (IC2012n) and was followed by a second in 2017/2018 (IC2017n). In sum, 31 Individual Monitoring Services (IMSs) entered 34 dosimetry systems in IC2012n, and 32 IMSs entered 33 dosimetry systems for IC2017n. Such exercises provided a rare opportunity to see how neutron dosemeters perform...

Hemodialysis deteriorates patients' physical, metabolic, and mental status. Clinical outcomes derived from inflammation determine a worse status but are less frequently identified. The objective of the study was to identify inflammatory determinants and the effect of SNP-related serum IL-6 and IL-10 levels on associated morbidity in hemodialysis. A sample of hemodialysis patients at IMSS Regional Hospital No.46 in Guadalajara ( n = 85) were tested using the Malnutrition Inflammation Score (MIS) and Patient Health Questionnaire-9 (PHQ-9) to assess the associated morbidity...

(1) Background: Ankle fractures are common injuries that typically require surgical treatment. Complications may arise, leading to reinterventions with poor recovery and reduced quality of life for patients. The aim of this study was to determine the number of patients who underwent surgical reintervention for ankle fractures, characteristics, and associated factors. (2) Methods: A cross-sectional study was conducted to analyze the number of patients requiring surgical intervention for ankle fractures at General Hospital Zone No1 IMSS in Colima over a period of two years...

Framed within the evolutionary framework, the Interpersonal Motivational System (IMS) theory suggests that eight distinct motivational impulses drive interpersonal human relationships, namely caregiving, social affiliation, attachment, rank-dominance, rank-submission, social play, cooperation, and sexuality. This theory has been widely applied in clinical practice, where psychopathology is viewed as the result of non-flexible or excessive activation of one system over another. Despite its clinical relevance, empirical studies aimed at measuring IMSs are scarce...

Our registry-based cross-sectional study covered 27,508 PwMS in Tehran with a point incidence rate and prevalence of 7.87 and 194.62 per 100,000 in 2021, respectively. We found that the incidence and prevalence of MS in Tehran are still on an upward trend which requires general attention and measures to overcome. The proportion of men with a family history of MS was significantly higher. Whilst IMSS deals with economic difficulties, it continues to collect new PwMS to reach regional-level coverage in Tehran for better MS care services...

Identifying risk factors associated with COVID-19 lethality is crucial in combating the ongoing pandemic. In this study, we developed lethality predictive models for each epidemiological wave and for the overall dataset using the Extreme Gradient Boosting technique and analyzed them using Shapley values to determine the contribution levels of various features, including demographics, comorbidities, medical units, and recent medical information from confirmed COVID-19 cases in Mexico between February 23, 2020, and April 15, 2022...

BACKGROUND: The COVID-19 pandemic represented a challenge in medical care. A tool would be very useful to establish the prognosis of in-hospital death that is reliable and can be applied to the Mexican population entitled to the IMSS. OBJECTIVE: To propose a prognostic scale to stratify patients with viral pneumonia COVID-19 in the emergency services. MATERIAL AND METHODS: A nested case-control study was conducted in a cohort of patients who were consecutively admitted to the emergency department with viral pneumonia COVID-19...

BACKGROUND: Resident academic satisfaction has been linked to academic performance and quality of care. OBJECTIVE: To analyze the perception of academic satisfaction in medical residents of the North Decentralized Administrative Operation Body 2 of the Instituto Mexicano del Seguro Social (IMSS), north of Mexico City. MATERIAL AND METHODS: Cross-sectional analytical study. A total of 346 resident physicians of different specialties and academic degrees were found, enrolled in the residence halls in the northern zone of the IMSS, Mexico City from January to February 2022...

The Revisa Médica del IMSS is considered a track of national and international scientific dissemination that presents the results of clinical research carried out within the Institute. Altmetrics, or alternative metrics, emerged as an alternative to citation-based metrics and allow authors to visualize the impact of their works that have not received citations to identify the characteristics of the readers who consult their published article. It is important that scientific journals have accurate information from their readers, as it will provide them with an overview of the use of the information produced in their area of expertise or in their institution...

BACKGROUND: In all international medical student (IMS) programs in China, language barriers between IMSs and Chinese patients greatly reduced the learning in clinical practice and brought great challenges to IMSs in their transition from preclinical to clinical practice. This study aimed to investigate the role of bilingual simulated patients (B-SPs) in IMSs learning of medical history collection in China. METHODS: 48 IMSs of grade 4 between October 2020 to Jan 2021 were enrolled in this study...

Fruit juices are one of the most widely consumed beverages worldwide, and their production is subject to strict regulations. Therefore, this study presents a methodology based on the use of headspace-gas chromatography-ion mobility spectrometry (HS-GC-IMS) in combination with machine-learning algorithms for the characterization juices of different raw material (orange, pineapple, or apple and grape). For this purpose, the ion mobility sum spectrum (IMSS) was used. First, an optimization of the most important conditions in generating the HS was carried out using a Box-Behnken design coupled with a response surface methodology...

Frailty poses a threat to the daily lives of healthy older adults, highlighting the urgent need for technologies that can monitor and prevent its progression. Our objective is to demonstrate a method for providing long-term daily frailty monitoring using an in-shoe motion sensor (IMS). We undertook two steps to achieve this goal. Firstly, we used our previously established SPM-LOSO-LASSO (SPM: statistical parametric mapping; LOSO: leave-one-subject-out; LASSO: least absolute shrinkage and selection operator) algorithm to construct a lightweight and interpretable hand grip strength (HGS) estimation model for an IMS...

Anti-inflammatory and analgesic medications (AAMs) are widely used in Mexico and the rest of the world. Their excessive acquisition can lead to waste, representing an unnecessary expense for families and the public health system. The aim of this study was to estimate the economic cost of the waste of unused AAMs collected by the National System for the Collection of Residues of Containers and Medications (SINGREM, the acronym in Spanish) in Mexico City during 2019. Data from SINGREM on discarded AAMs in Mexico City were classified by the type and quantity of drug, pharmaceutical dosage form, origin, dose, and the complete or incomplete condition of the package...
