A novel mortality risk score for emphysematous pyelonephritis: A multicenter study of the Global Research in the Emphysematous Pyelonephritis group.

Background: Emphysematous pyelonephritis (EPN) is a necrotizing infection of the kidney and the surrounding tissues associated with considerable mortality. We aimed to formulate a score that classifies the risk of mortality in patients with EPN at hospital admission.

Materials And Methods: Patients diagnosed with EPN between 2013 and 2020 were retrospectively included.

External validation of the 2017 ACR/EULAR classification criteria for inflammatory myopathies in a Mexican cohort: Role of autoantibodies in the diagnosis and classification of patients with inflammatory myopathies.

Objective: This retrospective study aimed to perform the first external validation of the ACR/EULAR classification criteria for inflammatory myopathy (IIM) in a Mexican dynamic cohort where the patients were evaluated with clinical and laboratory values. As secondary objectives, we presented the clinical characteristics of the patients and included antibodies other than anti Jo1 to evaluate their impact on our population.

Methodology: This study included 70 patients with IIM and 70 patients with differential diagnoses of IIM, according to the absolute score of the classification criteria.

Hypersensitivity reaction to Abiraterone, successful desensitization protocol in prostate cancer patient.

Introduction: In prostate cancer, androgens are key in the growth of both normal prostate and cancer cells. Abiraterone acetate inhibits CYP17, an important target in prostate cancer given its central role in the production of adrenal and tumor-derived androgens. Although abiraterone is generally well tolerated, common adverse effects such as hypertension, hypokalemia, and hepatotoxicity have been reported.

Eye and lid involvement as an uncommon feature of pemphigus foliaceus in a pediatric patient.

Pemphigus foliaceus (PF) is an autoimmune blistering disorder which affects the superficial layers of the epidermis with rare mucosal involvement. We present the case of a 12-year-old girl with PF involving the eyes and eyelids. A literature review of pediatric nonendemic PF revealed another two cases with ocular manifestations.

Identification of Providencia spp. clinical isolates co-producing carbapenemases IMP-27, OXA-24, and OXA-58 in Mexico.

Providencia rettgeri, belonging to the genus Providencia, had gained significant interest due to its increasing prevalence as a common pathogen responsible for healthcare-associated infections in hospitals. P. rettgeri isolates producing carbapenemases have been reported to reduce the efficiency of carbapenems in clinical antimicrobial therapy.

Characteristics and risk factors of COVID-19 breakthrough infections in Idiopathic Inflammatory Myopathies: Results from the COVAD study.

Objectives: To explore prevalence, characteristics and risk factors of COVID-19 breakthrough infections (BIs) in idiopathic inflammatory myopathies (IIM) using data from the COVID-19 Vaccination in Autoimmune Diseases (COVAD) study.

Methods: A validated patient self-reporting e-survey was circulated by the COVAD study group to collect data on COVID-19 infection and vaccination in 2022. BIs were defined as COVID-19 occurring ≥14 days after 2 vaccine doses.

Eyebrow trichoscopy in leprosy.

Background: Trichoscopy is a noninvasive technique based on the analysis of hair structures and the scalp, which allows for early diagnosis of different forms of alopecia.

Methods: We conducted a descriptive cross-sectional study in the Dermatology Department of Hospital Universitario "Dr. José Eleuterio González" in Monterrey, Northeastern Mexico.

The association of air pollution in respiratory allergy: Its impact in an industrial city.

Background: Asthma and allergic diseases have increased in recent decades and are more common in industrialized countries. Industrial areas with a considerably high number of inhabitants and vehicles can favor the presence of serious air pollution and therefore the appearance and exacerbation of respiratory allergy symptoms. The objective of this study was to determine the relationship between exposure to environmental pollutants with exacerbation of respiratory allergy.

Point of care thoracic ultrasound versus chest computed tomography in the approach of febrile neutropenia patients: A diagnostic accuracy cohort study.

Single-center prospective cohort diagnostic accuracy study. Our study aimed to evaluate the accuracy and reproducibility of Thoracic Ultrasound (TUS) in detecting pulmonary pathology in immunosuppressed patients. We conducted a single-center prospective study.

Impact of influenza vaccination history in the clinical course of older adults hospitalized with COVID-19.

Background And Purpose: Some studies have shown that influenza vaccination is associated with a lower risk of SARS-CoV-2 infection; in patients with COVID-19 infection, admission to intensive care is reduced, with less need for mechanical ventilation, shorter hospital stays, and reduced mortality. This study aimed to determine if a history of annual influenza vaccination impacts the clinical course of SARS-CoV-2 infection during hospitalization.

Methods: This was an observational, prospective, cohort study of patients older than 65 admitted to the COVID-19 unit from January to June 2021.

More about post-transplant cyclophosphamide in haploidentical grafts: full or reduced doses?

Haploidentical hematopoietic can be conducted on an outpatient basis but the two main reasons to accept into the hospital a patient in this setting are complications of the hematological toxicity and/or the cytokine-release syndrome. With the aim of reducing the post-transplant cyclophosphamide-dependent toxicity without compromising its effectivity, attempts to reduce the dose of post-transplant cyclophosphamide have been made: Decreases from the conventional total dose of post-transplant cyclophosphamide (100 mg/Kg) have been explored worldwide, showing that decreasing the total dose to even 50 mg/Kg significantly decreases the toxicity of the procedure without compromising its efficacy, safety and results. We present here the salient data of the attempts to diminish the doses of post-transplant cyclophosphamide which have been done and published worldwide, information that suggests that the conventional doses of post-transplant cyclophosphamide can be significantly reduced thus decreasing the toxicity, without compromising the effectiveness of the procedure, mainly the development of graft host disease.

Hepatocellular carcinoma with tumoral extension to the inferior vena cava and right atrium.

This case report describes an 81-year-old male with Child-Pugh B chronic liver disease presenting with dyspnea and atypical precordial pain. Evaluation revealed a third-degree atrioventricular block, necessitating temporary pacemaker placement. Portable cardiac ultrasound identified an intracavitary mass in the right atrium.

LL-37_Renalexin hybrid peptide exhibits antimicrobial activity at lower MICs than its counterpart single peptides.

An alarming global public health and economic peril has been the emergence of antibiotic resistance resulting from clinically relevant bacteria pathogens, including Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumonia, Acinetobacter baumannii, Pseudomonas aeruginosa, and Enterobacter species constantly exhibiting intrinsic and extrinsic resistance mechanisms against last-resort antibiotics like gentamycin, ciprofloxacin, tetracycline, colistin, and standard ampicillin prescription in clinical practices. The discovery and applications of antimicrobial peptides (AMPs) with antibacterial properties have been considered and proven as alternative antimicrobial agents to antibiotics. In this study, we have designed, produced, and purified a recombinant novel multifunctional hybrid antimicrobial peptide LL-37_Renalexin for the first time via the application of newly designed flexible GS peptide linker coupled with the use of our previously characterized small metal-binding proteins SmbP and CusF3H+ as carrier proteins that allow for an enhanced bacterial expression, using BL21(DE3) and SHuffle T7(DE3) Escherichia coli strains, and purification of the hybrid peptide via immobilized metal affinity chromatography.
