Heavily calcified lesions are encountered with increasing frequency during percutaneous coronary interventions (PCI). This poses a significant problem as it often leads to suboptimal stent expansion, which in turn is a major cause for stent restenosis and thrombosis. Various technologies have been developed to tackle this. The high-pressure balloon (OPN) seems to be a promising adjunct in treating undilatable lesions. In this concise mini review we highlight the use of HPB and we present the current status of technology implemented in complex PCI cases...

Histone deacetylases (HDACs) regulate myriad cellular processes by catalyzing the hydrolysis of acetyl-l-lysine residues in histone and nonhistone proteins. The Zn2+-dependent class IIb enzyme HDAC6 regulates microtubule function by deacetylating α-tubulin, which suppresses microtubule dynamics and leads to cell cycle arrest and apoptosis. Accordingly, HDAC6 is a target for the development of selective inhibitors that might be useful in new therapeutic approaches for the treatment of cancer, neurodegenerative diseases, and other disorders...

PURPOSE: Surgical resection still remains the mainstay of management of hepatocellular carcinoma (HCC). At present, Barcelona clinic liver cancer (BCLC) staging is the most widely used tool to guide treatment; however, criteria for offering surgery as curative treatment are restrictive. We aimed to evaluate short-term and long-term outcomes of HCC after resection, even for patients outside BCLC criteria for resection. METHODS: Data was collected from a prospective database from GI and HPB Department, Tata Memorial Hospital, Mumbai...

BACKGROUND: Patient-provider communication (PPC) is utilized as a value-based metric in pay-for-performance programs. We sought to evaluate the association of PPC with patient-reported health outcomes, as well as healthcare resource utilization among a nationally representative cohort of patients with hepato-pancreato-biliary (HPB) diagnoses. METHODS: Patients with HPB diseases were identified from the 2008-2014 Medical Expenditure Panel Survey cohort. A weighted PPC composite score was categorized using the responses from the CAHPS (Consumer Assessment of Healthcare Providers and Systems) survey as optimal, average, or poor...

Herein, we demonstrate a coating-etching strategy to directly synthesize hollow Prussian blue (PB) nanocubes with well-dispersed Ag nanoparticles (denoted as Ag-HPB). The method is accomplished by introduction of PB precursors, K3Fe(CN)6 and Fe(3+) into a reaction system containing AgNO3 and ascorbic acid, in which a series reactions contain formation of Ag nanoparticles, coating of PB on the nanoparticles, and diffusion of Ag into the PB frameworks occur. The strategy for preparation of the hollow structured Ag-HPB is intrinsically simple and does not require pre-preparation of any sacrificial templates or toxic etching agents...

In the present investigation, an intramolecular charge transfer (ICT) and aggregation induced emission enhancement (AIEE) active donor-acceptor-donor (D-A-D) system 5 having fumaronitrile as the acceptor and hexaphenylbenzene (HPB) as the donor moieties joined through rotatable phenyl rings has been designed and synthesized that is highly emissive in the solid state and exhibits stimuli-responsive reversible piezochromic behavior upon grinding and heating. Because of its AIEE characteristics, HPB derivative 5 undergoes aggregation to form fluorescent aggregates in mixed aqueous media that exhibit ratiometric fluorescence response toward aliphatic amines (primary/secondary/tertiary) and turn-off response toward aromatic amines and hence differentiates between them...

AIM AND OBJECTIVE: We examined the roles of two modifiable factors-health-promoting behaviors (HPB) and perceived stress-in predicting aneurysmal rupture. BACKGROUND: Unruptured intracranial aneurysm (UIA) detection produces significant stress and anxiety in patients because of the risk of rupture. Compared to non-modifiable risk factors for rupture such as age, gender, and aneurysm size/location, less attention has been given to modifiable risk factors. Two modifiable factors, HPBs and perceived stress, have hardly been examined as potential predictors of rupture...

Interferon regulatory factor-8 (IRF-8) is critical for Th1 cell differentiation and negatively regulates myeloid cell development including myeloid-derived suppressor cells (MDSC). MDSC expand during infection with various pathogens including the gastrointestinal (GI) nematode Heligmosomoides polygyrus bakeri (Hpb). We investigated if IRF-8 contributes to Th2 immunity to Hpb infection. Irf8 expression was down-regulated in MDSC from Hpb-infected C57BL/6 (B6) mice. IRF-8 deficient Irf8-/- and BXH-2 mice had significantly higher adult worm burdens than B6 mice after primary or challenge Hpb infection...

Endoscopic ultrasound (EUS) is increasingly used in the management of hepatobiliary lesions, allowing staging and tissue acquisition. It is operator-dependent, and fine needle aspiration (FNA) of solid lesions provides an auditable standard; high-volume centres have shown excellent results for solid pancreatic lesion FNA with sensitivities of 92%-97%. The British Society of Gastroenterology guidelines stress that clinical quality should determine service provision, with geographical accessibility a secondary consideration...

The enhanced recovery after surgery (ERAS) program has reduced postoperative morbidity and duration of hospital stay but not mortality in patients undergoing hepatopancreatobiliary (HPB) surgery. Many HPB patients suffer from cancer cachexia, a syndrome of severe weight and muscle loss. This may affect outcomes of HPB surgery even within an ERAS program. A tailored ERAS approach may be essential in further improving outcome in this vulnerable patient category.
