Considerations on genetic engineering: regarding the birth of twins subjected to gene edition.

In this essay, the bioethical implications of the recent genetic manipulation in human embryos with CRISPR-Cas9 to eliminate the CCR5 gene and the birth of a pair of discordant twin girls are analyzed. The experiment was disseminated via social media. The main bioethical flaws identified include the justification of the model, the informed consent process and the lack of disclosure of evident conflicts of interest.

Independent parameters of left atrium function in hypertensive heart disease.

Background: The left atrium reservoir function has an important role in the global cardiac performance and is determined by multiple cardiac and extra-cardiac factors. A new parameter is introduced, the independent strain, which quantifies left atrium reservoir phase deformation during isovolumetric relaxation.

Aims: Is evaluated whether independent strain can identify intrinsic atrial myocardial damage in hypertension.

Changes in the commercial brand of tacrolimus lead to subtherapeutic trough levels and acute rejection in renal transplant recipients.

Background: The vigilance of tacrolimus (TAC) trough levels is an essential part of renal transplant follow up. Reduced TAC trough levels and high variability are related to adverse outcomes. The aim of this study was to evaluate the impact of brand changes on tacrolimus (TAC) subtherapeutic (SubT) trough levels, acute rejection (AR), and kidney function.

Design: A retrospective subanalysis of a prospective observational study conducted in 1998, 2004, 2010 and 2016 was carried out.

Setting: Intensive Care Units (ICUs) in Mexico.

Tissue talks: immunophenotype of cells infiltrating the graft explains histological findings and the benefits of belatacept at 10 years.

Previously, we found a substantial number of regulatory T cells (T ) and fewer senescent and T helper type 17 (Th17) and a decrease in interstitial fibrosis (IF) in 12-month graft biopsies in belatacept versus cyclosporin (CNI)-treated patients [Belatacept Evaluation of Nephroprotection and Efficacy as First-line Immunosuppression Trial (BENEFIT) study]. Seven years after kidney transplantation (KT), mean estimated glomerular filtration rate (eGFR), patient and graft survival were significantly higher with belatacept versus CNI treatment. The aim of this study was to determine whether the immunophenotypes of inflammatory and regulatory cell subsets infiltrating the grafts contribute to the BENEFIT's clinical findings a decade after KT.

[Forearm diaphyseal fractures in pediatric patients. Review of treatment results].

Objective: To describe the most common types of fractures in patients under 16 years of age at the forearm level, and to evaluate depending on the level of the fracture, the treatment with better results.

Material And Methods: We perform a retrospective analysis to determine the frequency of forearm fractures in patients under 16 years, in the period from January 2013-July 2017. The following diagnoses were entered into the system: forearm fracture, radius fracture, ulnar fracture and bilateral fracture.

Analyses of LMNA-negative juvenile progeroid cases confirms biallelic POLR3A mutations in Wiedemann-Rautenstrauch-like syndrome and expands the phenotypic spectrum of PYCR1 mutations.

Juvenile segmental progeroid syndromes are rare, heterogeneous disorders characterized by signs of premature aging affecting more than one tissue or organ starting in childhood. Hutchinson-Gilford progeria syndrome (HGPS), caused by a recurrent de novo synonymous LMNA mutation resulting in aberrant splicing and generation of a mutant product called progerin, is a prototypical example of such disorders. Here, we performed a joint collaborative study using massively parallel sequencing and targeted Sanger sequencing, aimed at delineating the underlying genetic cause of 14 previously undiagnosed, clinically heterogeneous, non-LMNA-associated juvenile progeroid patients.

Streptococcus pneumoniae Serotype 3 in Mexico (1994 to 2017): Decrease of the Unusual Clonal Complex 4909 Lineage following PCV13 Introduction.

expressing serotype 3 has a high virulence and a high case fatality ratio. Most studies of serotype 3 pneumococci have focused on a single lineage, the widespread sequence type 180 (ST180). To evaluate the serotype 3 lineages causing infections in Mexico, we characterized 196 isolates recovered from 1994 to 2017.

An evaluation of multidrug-resistant Escherichia coli isolates in urinary tract infections from Aguascalientes, Mexico: cross-sectional study.

Background: Uropathogenic Escherichia coli (UPEC) are one of the main bacteria causing urinary tract infections (UTIs). The rates of UPEC with high resistance towards antibiotics and multidrug-resistant bacteria have increased dramatically in recent years and could difficult the treatment.

Methods: The aim of the study was to determine multidrug-resistant bacteria, antibiotic resistance profile, virulence traits, and genetic background of 110 E.

[Lower glenohumeral recurrent luxation () arthroscopic treatment, literature review and case report].

It is extremely important to take into account the complications of inferior gelnohumeral dislocation, which, although infrequent, may become incapacitating in the medium and long term, even in some cases reported, endangering the life of the same. We present the case of a young adult patient diagnosed with inferior rectal glenohumeral dislocation (luxatio erecta), with Bankart lesion and Hill Sachs lesion, treated by arthroscopy with repair of the Bankart lesion, plication of the lower capsular recess and remplissage. We evaluated the functionality of the patient at 18 months with the UCLA scale, obtaining a final score of 30 points with good functional results.

Changing trends in serotypes of S. pneumoniae isolates causing invasive and non-invasive diseases in unvaccinated population in Mexico (2000-2014).

Objective: Introduction of pneumococcal conjugate vaccines (PCV) targeted against a limited number of serotypes substantially decreased invasive (IPD) and non-invasive pneumococcal diseases (NIPD) but it was accompanied by non-vaccine type replacement disease. After 9 years of introduction of PCV in Mexico, we analyze the evidence of the indirect effects on IPD and NIPD serotype distribution among groups not targeted to receive the vaccine.

Methods: From January 2000 to December 2014, pneumococcal strains isolated from IPD and NIPD cases from patients ≥5 years of age from participant hospitals of the SIREVA II (Sistema Regional de Vacunas) network were serotyped.

A novel homozygous variant in SERPINH1 associated with a severe, lethal presentation of osteogenesis imperfecta with hydranencephaly.

Osteogenesis imperfecta (OI) is a genetic disorder characterised by low bone mineral density resulting in fractures. 85-90% of patients with OI carry a variant in the type 1 collagen genes, COL1A1 and COL1A2, which follows an autosomal dominant pattern of inheritance. However, within the last two decades, there have been growing number of variants identified in genes that follow an autosomal recessive pattern of inheritance.

[Reduction of omalgia in laparoscopic cholecystectomy: clinical randomized trial ketorolac vs ketorolac and acetazolamide].

Background: Laparoscopy cholecystectomy for the surgical treatment of cholelithiasis has been considered the gold standard. The referred pain to the shoulder (omalgia) may be present to 63% of the patients and limits outpatient management.
