OBJECTIVES: Double-guidewire cannulation (DGC) for selective biliary access has been associated with increased risk of post-ERCP pancreatitis (PEP) in patients who have had pancreatic duct (PD) contrast injection. The objective of this study was to determine whether DGC increases PEP risk in standard risk individuals when controlling for procedural aspects such as PD contrast injection. METHODS: Consecutive adults with native papillae who underwent endoscopic retrograde cholangiopancreatography from 2009 to 2014 were retrospectively identified, and clinical data were collected...

Parkinson's disease (PD) is a degenerative movement disorder causing progressive disability that severely affects patients' quality of life. While early treatment can produce significant benefits for patients, the mildness of many early signs combined with the lack of accessible high-frequency monitoring tools may delay clinical diagnosis. To meet this need, user interaction data from consumer technologies have recently been exploited towards unsupervised screening for PD symptoms in daily life. Similarly, this work proposes a method for detecting fine motor skills decline in early PD patients via analysis of patterns emerging from finger interaction with touchscreen smartphones during natural typing...

Time-dependent density functional theory calculations combined with the Marcus theory of electron transfer (ET) were applied on the molecular photocatalyst [(tbbpy)2Ru(tpphz)PdCl2]2+ in order to elucidate the light-induced relaxation pathways populated upon excitation in the longer wavelength range of its absorption spectrum. The computational results show that after the initial excitation, metal (Ru) to ligand (tpphz) charge transfer (MLCT) triplet states are energetically accessible, but that an ET toward the catalytic center (PdCl2) from these states is a slow process, with estimated time constants above 1 ns...

Precision medicine just witnessed two breakthroughs in oncology in 2017. Pembrolizumab (Keytruda), Merck's anti-programmed cell death-1 (PD-1) monoclonal antibody (mAb), received accelerated approval in May 2017 by the US Food and Drug Administration for the treatment of adult and pediatric patients with unresectable or metastatic solid tumors that have been identified as having microsatellite instability-high (MSI-H) or deficient DNA mismatch repair (dMMR). Shortly after, nivolumab (Opdivo), Bristol-Myers Squibb's anti-PD-1 mAb, gained an accelerated approval in August 2017 for adult and pediatric patients with MSI-H or dMMR metastatic colorectal cancer that has progressed after standard chemotherapy...

Parkinson's disease (PD) is treated by medication, less with deep brain stimulation and physiotherapy. Different opinions on the clinical meaningfulness of the physiotherapy or recommended intensive physiotherapy were found. Our objectives were to design intensive target-based physiotherapy for upper extremities suitable for telerehabilitation services and examine the clinical meaningfulness of the exergaming at an unchanged medication plan. A telerehabilitation exergaming system using the Kinect sensor was developed; 28 patients with PD participated in the study...

OBJECTIVE: This study aimed to systematically review the effects of currently prescribed antiparkinson medication on cognition in patients with mild-to-moderate Parkinson's disease (PD) who were either cognitively intact or mildly impaired. METHODS: English- and French-language studies published between 1969 and 2017 were accessed via MedLine, PsychNET, EMBASE and EBSCO databases. Methodological quality (MQ) was evaluated with the quality assessment instrument of the Cochrane Collaboration Depression, Anxiety and Neurosis Review (scores from 0% to 44% indicate very low quality; scores from 45% to 64% indicate low quality; scores from 65% to 84% indicate medium quality; and scores from 85% to 100% indicate high quality)...

ABSTRACTObjective:Over two-thirds of Parkinson's disease (PD) patients experience comorbid neuropsychiatric symptoms, which adversely impact their quality of life and often require intervention. There is a preference for non-pharmacological, psychological approaches in addressing these symptoms. Given mobility limitations, travel burden, and cost, accessibility to psychological treatment can be problematic in this population. There has been a recent shift toward delivering care via telehealth in PD. Accordingly, this review aimed to examine remotely delivered psychological interventions for PD patients...

The scope and limitation of mono-selective N-arylation of various amines using aryl or heteroaryl tosylates are presented. Air-stable and easily accessible Pd(OAc)2/CM-phos catalyst system was found capable to deal with a wide range of aryl tosylate substrates as well as amine nucleophiles, including primary and secondary cyclic/acyclic aliphatic amines, and anilines. NH-bearing heterocycles such as indole, carbazole, pyrrole, 10-phenothiazine and 10-phenoxazine were shown to be feasible coupling partners under this catalytic system...

BACKGROUND: Co-infection with HIV negatively impacts the progression of chronic hepatitis B virus (HBV) infection, including causing rapid progression to liver fibrosis. Sub-Saharan Africa represents arguably the most important intersection of high endemicity of both chronic hepatitis B virus (HBV) infection and HIV infection. METHODS: We recruited 46 HBV/HIV-co-infected; 47 HBV-monoinfected; 39 HIV-monoinfected; and 37 HBV/HIV-uninfected patients from Tygerberg Hospital, Cape Town, South Africa...

Direct access to pharmaceutically attractive benzo-fused nine-membered heterocyclic alkenes 3 with a trifluoromethyl carbinol moiety was achieved via a palladium-catalyzed double-decarboxylative formal ring-expansion process from six-membered trifluoromethyl benzo[ d ][1,3]oxazinones 1 to nine-membered trifluoromethyl benzo[ c ][1,5]oxazonines 3 in the presence of vinylethylene carbonates 2 . Generation of a Pd-π-allyl zwitterionic intermediate was proposed in the catalytic cycle. The trifluoromethyl group in the benzoxazinanones 1 plays an important role throughout the transformation...

Background: Parkinson's disease (PD) motor symptoms can fluctuate and may not be accurately reflected during a clinical evaluation. In addition, access to movement disorder specialists is limited for many with PD. The objective was to assess the impact of motion sensor-based telehealth diagnostics on PD clinical care and management. Methods: Eighteen adults with PD were randomized to control or experimental groups. All participants were instructed to use a motion sensor-based monitoring system at home one day per week, for seven months...

Synthetic approaches towards N -acetylgalactosamine (GalNAc) have been attracting considerable interest since this compound is known for its pivotal role in cell-cell interaction and receptor induced cell signaling. Herein, we present a synthetic route in which two of the four stereogenic centers present in the target compound are derived from enantiopure tartaric acid being selectively converted to epoxy alcohols. The key step is the Pd-catalyzed, stereo- and regioselective epoxide opening and subsequent nucleophilic substitution of an azide functionality...

Pierce's disease (PD) limits the cultivation of Vitis vinifera grape cultivars in California, across the southern United States and into South America. Resistance has been well characterized in V. arizonica, and one resistance locus has been identified (PdR1). However, resistance is poorly characterized in most other grape species. We tested a wide range of Vitis species from the southwestern United States for resistance to PD and used nuclear and chloroplast markers to phenotypically and genetically select a diverse set of resistant accessions...

OBJECTIVE: Deep brain stimulation (DBS) is an established treatment modality for Parkinson's Disease (PD). The first DBS for PD in the Philippines was done at the Philippine Movement Disorder Surgery Center (PhilMove) in 2006. There is no Philippine data on DBS for PD. We aim to determine the motor improvement and reduction in medication dosage of all PD patients who underwent DBS at PhilMove. METHODS: This is a retrospective study of all PD patients (n=17) who underwent DBS from 2006-2016...

We report herein the scalable total synthesis of the secondary metabolite, mycocyclosin, initially isolated from Mycobacterium tuberculosis. Mycocylosin bears a highly strained 3,3'-dityrosine biaryl system which arises biosynthetically from an intramolecular oxidative dehydrogenative cross-coupling of cyclo(l-Tyr-l-Tyr) (cYY) catalyzed by the P450 enzyme CYP121. CYP121 is found exclusively in M. tuberculosis. Scalable access to mycocyclosin and related derivatives via a Pd(II)-catalyzed macrocyclization is anticipated to facilitate the biological evaluation of these compounds as novel tuberculosis antimicrobials...

We report a novel Pd(II)-initiated Catellani-type reaction that utilizes widely accessible aryl boronic acids as the substrates instead of aryl halides, thereby greatly expanding the existing paradigm of this powerful transformation. This tentatively called "Borono-Catellani reaction" was promoted by a cooperative catalysis of Pd(OAc)2 and the inexpensive 5-norbornene-2-carbonitrile. Practicality is the striking feature of the reaction: it is run at ambient temperature under air while no phosphine ligand is needed...
