Gastroesophageal and extraesophageal reflux are prevalent and costly diseases. Recognition of the pathogenicity of nonacid reflux has stimulated interest in alternatives to acid-targeting diagnostics and therapeutics. Pepsin is the most deleterious enzyme in refluxate, eliciting inflammatory and carcinogenic effects irrespective of acid. Its presence in all refluxate and detection in saliva have situated pepsin as the most widely researched biomarker for reflux today. This review summarizes emerging findings regarding pepsin-mediated damage during reflux and developments in pepsin-targeting diagnostics.

New evidence supports a role for pepsin in epithelial--mesenchymal transition, an important process in carcinogenesis and fibrosis. The first global transcriptomic analysis of pepsin-exposed laryngeal cells was described, yielding evidence of a putative airway pepsin receptor. Evaluation of pepsin diagnostics highlighted the need for rigorous validation in which pepsin concentrations are corroborated by a secondary quantitative assay, and reflux is confirmed or excluded by multichannel intraluminal impedance pH testing. Standards for sample collection and storage, and normative and pathological values are lacking.

Progress continues to be made in our understanding of pepsin-mediated damage with implications for novel therapeutic strategies. Salivary pepsin diagnostics continue to garner interest; however, further work appears necessary to improve their accuracy and reproducibility.

Acute lymphoblastic leukemia (ALL), a common blood cancer, is characterized by the interaction between genetic and environmental factors. Several variants of the Methylenetetrahydrofolate reductase (MTHFR), mainly the C677T (rs1801133), may affect susceptibility to ALL.

The authors conducted this case-control study to evaluate the relationship between this variant of the MTHFR gene and the risk of ALL.

Forty-one patients with ALL and 35 non-ALL controls recruited in this study were genotyped utilizing polymerase chain reaction-restriction fragment length polymorphism methodology.

The MTHFR 677CT genotype was significantly more frequently found in patients with ALL having a 2-fold increase in risk (P <0.01).

Our results suggest that rs1801133 of MTHFR is a predictive risk marker to ALL in Tunisian ALL.

Fifty-eight patients diagnosed with PRES were included in this study. The data of PRES cases from 10 departments of pediatric hematology/oncology were analyzed. The mean age of the patients at the time of diagnosis of PRES was 8.95±3.66 years. Most patients (80.4%) had a primary diagnosis of acute leukemia. Patients received chemotherapy (71.4%) and/or used steroids within 14 days before the diagnosis of PRES (85.7%). Hypertension was found in 83.9% of the patients. KIF18A-IN-6 Twenty-six patients had infections and 22 of them had febrile neutropenia. The most common electrolyte disorders were hypocalcemia, hypomagnesemia, and hypopotassemia. Six patients had tumor lysis syndrome and 4 had inappropriate antidiuretic hormone syndrome. Magnetic resonance imaging was used for diagnosis in all patients. The most commonly involved regions by magnetic resonance imaging were occipital (58%), parietal (51%), and frontal lobes (45%), respectively. Twenty-five patients required intensive care and 7 patients were intubated. In conclusion, PRES may develop during the follow-up and treatment of hematological diseases. In addition to steroid and intense combined chemotherapies, immunosuppressive agents and hypertension are also factors that may be responsible for PRES.Pediatric opsoclonus-myoclonussyndrome (OMS) is a rare autoimmune disorder of which 50% are associated with neuroblastoma (NB). We investigated whether surface-binding autoantibodies in OMS can enhance natural killer (NK) cell-mediated cytotoxicity in these patients. OMS immunoglobulin G (IgG) bound to NB cell lines and NK cell-mediated cytotoxicity to NB cells was enhanced after preincubation with OMS-IgG, but not IgG from NB without OMS or healthy controls. Activation of NK cells by surface-binding autoantibodies may be an additional mechanism of antitumor immunity in children with NB and OMS.
The PARTNER 3 trial was conducted to compare outcomes after transcatheter aortic valve replacement (TAVR) with a balloon-expandable valve and surgical aortic valve replacement (SAVR) in individuals at low surgical risk with aortic stenosis. Recently reported rates of death, stoke and valve thrombosis in the TAVR arm have raised concerns about the longevity of this intervention in low-risk individuals. It is incumbent on all members of the Heart Team to understand the potential consequences of these findings.

TAVR was initially superior to SAVR at 1 year for a primary composite endpoint of death, stroke and rehospitalization. Results at 2 years now indicate noninferiority. Potential causative factors, comparisons with other transcatheter valves and implications for patients, providers and trainees are explored. Recommendations are additionally provided regarding TAVR and SAVR in individuals with aortic stenosis.

Concerns regarding the longevity of TAVR in low-risk individuals notwithstanding, results from PARTNER 3 indicate that TAVR is at least noninferior to SAVR out to 2 years. Longer follow-up will be required to determine whether these newly founded concerns are justifiable.
