Streptococcus mutans is the primary etiological agent of dental caries and causes tooth decay by forming a firmly attached biofilm on tooth surfaces. Biofilm formation is induced by the presence of sucrose, which is a substrate for the synthesis of extracellular polysaccharides, but not in the presence of oligosaccharides. Nonetheless, in this study, we found that raffinose, which is an oligosaccharide with an intestinal regulatory function and antiallergic effect, induced biofilm formation by S. mutans in a mixed culture with sucrose which was at concentrations less than those required to induce biofilm formation directly...

Pulmonary arterial hypertension (PAH), at one time a largely overlooked disease, is now the subject of intense study in many academic and biotech groups. The availability of new treatments has increased awareness of the condition. This in turn has driven a change in the demographics of PAH, with an increase in the mean age at diagnosis. The diagnosis of PAH in more elderly patients has highlighted the need for careful phenotyping of patients and for further studies to understand how best to manage pulmonary hypertension associated with, for example, left heart disease...

The therapeutic heart failure armamentarium has evolved from drugs to transplantation to devices through further understanding of its complex pathophysiology and pathogenesis. Current medications capitalize on our evolving understanding of the sympathetic and renin-angiotensin-aldosterone systems that subsequently promote both beneficial and maladaptive responses that ultimately yield a decrease in cardiac function. Despite these advancements, the prevalence of heart failure continues to rise and carries a significant burden on our patients and health care system...

Amy Sarma, Nandita S Scott
Despite continued advances in the field, cardiovascular disease remains the leading cause of death in women in the USA with an annual mortality rate that has remained higher for women as compared to men. The factors leading to this sex difference remain incompletely understood. Likely contributors include atypical symptoms at presentation and lack of recognition of cardiovascular risk by women and their providers alike. In addition, women have a higher burden of comorbidities at the time of disease diagnosis and can have differential pathophysiological mechanisms of their acute events...

Primary immunodeficiencies (PIDs) are a widely heterogeneous group of inherited defects of the immune system consisting of many clinical phenotypes with at least 300 underlying genetic deficits currently known. Patients with PIDs can present with, or develop during the course of their life, a susceptibility to recurrent and chronic infection along with autoimmune, allergic, inflammatory, and/or proliferative disorders, all potentially leading to end-organ damage. In recent years, a combination of basic and clinical research has greatly improved understanding of the underlying immunological and genetic defects in PIDs, leading to improved diagnosis, classification, and treatment approaches...

The modern clinical practice is characterized by intensive introduction of innovative technologies for improving treatment and diagnostic procedures, minimizing their impact on the patient, complications rate and economic reasons. One of the priorities in this area is both diagnostic and therapeutic endoscopy. The degree of practical use of innovative endoscopic technologies depends on not only the quality of care, but also their economic reasons. Endoscopic treatment has become the method of choice for gastrointestional bleeding, extraction of foreign bodies, obstructive jaundice, polyps of the gastrointestinal tract, achalasia, esophageal strictures, etc...

REVIEW
Nidhi Rawal, Nada Yazigi
The past decade has seen major advances in the field of transplantation; it is the treatment of choice for many with intestinal failure. One-year mortality from pediatric intestinal transplantation has significantly declined, from 30% to 10% to 15% nationally, mainly due to a multidisciplinary approach in transplant centers. Pediatric age carries special considerations along the spectrum of care that continue to cause challenges but also offers growth opportunities. Pediatric intestinal transplantation indications and timing are changing as a result of new developments in diagnostic and treatment tools...

Maternal mortality is an important indicator of health in populations around the world. The distribution of maternal mortality ratio globally shows that middle- and low-income countries have ∼99% of the mortality burden. Most countries of Latin America are considered to be middle- or low-income countries, as well as areas of major inequities among the different social classes. Medical problems in pregnancy remain an important cause of morbidity and mortality in this region. Previous data indicate the need for a call to action for adequate diagnosis and care of medical diseases in obstetric care...
