Underdiagnosis of umbilical hernias in CT scans in a multicenter study - the radiologically neglected pathology and its surgical implications.

Purpose: Umbilical hernias (UH) have a higher prevalence than previously considered. With the high workload radiologists must endure, UH can be missed when interpreting a computed tomography scan (CT). The clinical implications of its misdiagnosis are yet to be determined.

Guidelines for the management of coagulation disorders in patients with cirrhosis.

Coagulation management in the patient with cirrhosis has undergone a significant transformation since the beginning of this century, with the concept of a rebalancing between procoagulant and anticoagulant factors. The paradigm that patients with cirrhosis have a greater bleeding tendency has changed, as a result of this rebalancing. In addition, it has brought to light the presence of complications related to thrombotic events in this group of patients.

Cumulative steroid dose in hospitalized patients and COVID-19-associated pulmonary aspergillosis.

Background: Severe COVID-19 elicits a hyperimmune response frequently amenable to steroids, which in turn increase the risk for opportunistic infections. COVID-19 associated pulmonary aspergillosis (CAPA) is a complication known to be associated with immunomodulatory treatment. The role of cumulative steroid dose in the development of CAPA is unclear.

Early increase of serum ferritin among COVID-19 patients is associated with need of invasive mechanical ventilation and with in-hospital death.

Background: COVID-19 may trigger an acute hyperinflammatory syndrome characterised by heightened levels of acute phase reactants and is associated with adverse outcomes among hospitalised individuals. The relationship between 48-hour changes in acute phase reactants and adverse outcomes is unclear. This study evaluated the relationship between change in four acute phase reactants (interleukin-6, procalcitonin, ferritin, and C-reactive protein), and the risk for in-hospital death and invasive mechanical ventilation.

Approach to the patient with cholestasis and jaundice syndrome. Joint AMH, AMG, and AMEG scientific position statement.

The term cholestasis refers to bile acid retention, whether within the hepatocyte or in the bile ducts of any caliber. Biochemically, it is defined by a level of alkaline phosphatase that is 1.67-times higher than the upper limit of normal.

Stratifying risk outcomes among adult COVID-19 inpatients with high flow oxygen: The R4 score.

Background: High flow oxygen therapy (HFO) is a widely used intervention for pulmonary complications. Amid the coronavirus infectious disease 2019 (COVID-19) pandemic, HFO became a popular alternative to conventional oxygen supplementation therapies. Risk stratification tools have been repurposed -and new ones developed- to estimate outcome risks among COVID-19 patients.

Species distribution and antifungal susceptibility patterns of Aspergillus isolates from clinical specimens and soil samples in Mexico.

Unlabelled: This study aimed to assess the species distribution and antifungal susceptibility patterns of 200 strains of Aspergillus isolated from clinical specimens (n = 146) and soil samples (n = 54) in Mexico. ITS, β-tubulin, and calmodulin DNA sequencing was performed for species identification. Broth microdilution susceptibility testing for amphotericin B, voriconazole, posaconazole, itraconazole, isavuconazole, anidulafungin, caspofungin, and micafungin was done according to CLSI for all strains.

[Shortening in the Tp-e/QTc ratio after angioplasty in patients with acute coronary syndrome].

Objetivo: La dispersión transmural de la repolarización ventricular (DTMRV) es un factor de riesgo para muerte en pacientes con síndrome isquémico coronario agudo (SICA). Con el objetivo de conocer el efecto de la realización de angioplastia sobre la DTMRV, se estudió la relación Tp-f/QTc en pacientes con SICA sometidos a angioplastia.

MÉtodo: Se diseñó un estudio observacional, retrospectivo y descriptivo.

Iatrogenic left vertebral artery pseudoaneurysm treated with a covered stent.

Vertebral artery pseudoaneurysm usually occurs after major trauma, but it can arise spontaneously after trivial injury. Clinical manifestations are often related to alterations in the posterior brain circulation. CT and angiography are usually the diagnostic methods of choice.

The Mexican consensus on alcoholic hepatitis.

Alcoholic hepatitis is a frequent condition in the Mexican population. It is characterized by acute-on-chronic liver failure, important systemic inflammatory response, and multiple organ failure. The severe variant of the disease implies elevated mortality.

Incidental benign metastasizing leiomyoma in a patient with bone sarcoma: a case report.

Background. The benign metastasizing leiomyoma is an exceptionally rare entity; it presents with ectopic leiomyoma nodules with a benign pattern. Symptoms vary according to the anatomic location.
