DNA Identification in Breast Milk from Mexican Women with Chagas Disease.

(1) Background: Chagas disease is a public health problem affecting nearly 2 million women of reproductive age in Latin America. From these, 4-8% can transmit the infection to the foetus through the vertical route, whereas horizontal transmission through milk during breastfeeding remains controversial. Therefore, the presence of () DNA in the milk of women seropositive for Chagas disease was analysed to determine whether a relationship with the infection of their children can exist.

Antibody persistence 7 years after hepatitis-A vaccine in children with human immunodeficiency virus infection.

Background: HIV-infected children have a higher risk of presenting infections, including the hepatitis A virus (HAV). The inactivated HAV vaccine is immunogenic in immunocompetent hosts; however, there are insufficient studies on the duration of seroprotection in HIV-infected children.

Methods: An analytical cohort study was conducted.

Immunoglobulin-resistant Kawasaki disease.

Background: Kawasaki disease is a systemic vasculitis that affects small and medium-sized vessels, primarily the coronary arteries. First-line treatment includes intravenous immunoglobulin (IVIG) and acetylsalicylic acid; however, 20% do not respond adequately despite treatment. We describe a case treated with etanercept after initial IVIG failure, showing a good response.

The Real Practice Prescribing Antibiotics in Outpatients: A Failed Control Case Assessed through the Simulated Patient Method.

The first level of medical care provides the largest number of consultations for the most frequent diseases at the community level, including acute pharyngitis (AP), acute diarrhoea (AD) and uncomplicated acute urinary tract infections (UAUTIs). The inappropriate use of antibiotics in these diseases represents a high risk for the generation of antimicrobial resistance (AMR) in bacteria causing community infections. To evaluate the patterns of medical prescription for these diseases in medical offices adjacent to pharmacies, we used an adult simulated patient (SP) method representing the three diseases, AP, AD and UAUTI.

Spotted fever rickettsioses. Study of cases reported in a secondary care pediatric hospital of northeastern Mexico, 2012-2022.

Objective: To describe the characteristics of patients hospitalized for spotted fever rickettsiosis, as well as the risk factors associated with poor prognosis.

Material And Methods: Data from medical records of patients hospitalized between August 2012 and July 2022 were collected.

An expert panel opinion on protection against pertussis in Mexico: The role of acellular and whole-cell vaccines.

Pertussis is a highly contagious disease caused by Bordetella pertussis, which may be preventable by vaccination. There are two types of vaccines: whole-cell vaccines and acellular vaccines. Since pertussis control worldwide is heterogeneous, re-emergence of whooping cough has been observed in some countries.

Genomic analysis of virulence factors and antimicrobial resistance of group B Streptococcus isolated from pregnant women in northeastern Mexico.

Introduction: Group B Streptococcus (GBS) causes infections in women during pregnancy and puerperium and invasive infections in newborns. The genes lmb, cylE, scpB, and hvgA are involved with increased virulence of GBS, and hypervirulent clones have been identified in different regions. In addition, increasing resistance of GBS to macrolides and lincosamides has been reported, so knowing the patterns of antibiotic resistance may be necessary to prevent and treat GBS infections.

Universal influenza vaccination: a Mexican Expert Position Paper.

Objective: Influenza is a costly disease for the population. It is a cause of seasonal morbidity and mortality, epidemics and pandemics or syndemics. Given the variability of the virus, surveillance systems are implemented in order to update the strains and include them in the annual influenza vaccine.

Cervicovaginal and rectal colonization by group B Streptococci in Mexican women with full-term pregnancies.

Background: A pregnant woman rectally or vaginally colonized by group B Streptococcus can infect her newborn.

Patients And Methods: Prospective, cross-sectional, analytical 24-month study in pregnant women. Women in labor with ≥ 36 weeks of gestation were included.

Role of and Other Environmental Factors in the Development of Gastric Dysbiosis.

Microbiomes are defined as complex microbial communities, which are mainly composed of bacteria, fungi, and viruses residing in diverse regions of the human body. The human stomach consists of a unique and heterogeneous habitat of microbial communities owing to its anatomical and functional characteristics, that allow the optimal growth of characteristic bacteria in this environment. Gastric dysbiosis, which is defined as compositional and functional alterations of the gastric microbiota, can be induced by multiple environmental factors, such as age, diet, multiple antibiotic therapies, proton pump inhibitor abuse, status, among others.

Covid-19 Incidence and Mortality by Age Strata and Comorbidities in Mexico City: A Focus in the Pediatric Population.

SARS-COV2 appears less frequently and less severely in the pediatric population than in the older age groups. There is a need to precisely estimate the specific risks for each age group to design health and education policies suitable for each population. This study aimed to describe the risk of death in SARS-COV2 infected subjects by age group and according to the presence of comorbidities.

Coronavirus Disease-2019 Survival in Mexico: A Cohort Study on the Interaction of the Associated Factors.

The pandemic caused by the new coronavirus Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) is currently affecting more than 200 countries. The most lethal clinical presentation is respiratory insufficiency, requiring attention in intensive care units (ICU). The most susceptible people are over 60 years old with comorbidities.

Impact of the use of multiplex PCR on etiological diagnosis and treatment of acute respiratory infections in a private hospital of the north of the country.

Background And Objective: Diseases of the respiratory system represent one of the leading causes of medical care and antibiotic prescriptions. Currently, new technologies are used for the diagnosis of respiratory diseases of viral origin, such as the FilmArray Respiratory Panel, approved in 2012 by the FDA. The purpose of this study was to identify the correlation between the diagnosis and treatment of respiratory tract infections and the result of the polymerase chain reaction test for respiratory viruses.

Measles outbreak during the COVID-19 pandemic in Mexico.

Measles is an exanthematous disease caused by a virus of the Morbillivirus genus. On February 23, 2020, the exanthema began in the first confirmed case of measles this year. At the same time, on February 28, 2020, the first case of the new coronavirus disease (COVID-19) was confirmed.

COVID-19 pandemic: challenges ahead.

Since December 2019, health systems worldwide have faced the pandemic caused by the new severe acute respiratory syndrome coronavirus 2. The pandemic began in China and has spread throughout the world. This new coronavirus has a high transmission capacity and elevated lethality in people over 60 years old and in those with risk factors (obesity, diabetes, and systemic arterial hypertension); those characteristics have a different proportion in each country.
