Summary Background Geographical variations in Crohn's disease (CD) suggest that the environment has a role in the pathogenesis of this condition. Aims To describe the spatial distribution and the clustering of CD cases in France, and to assess the relationship between the prevalence of CD and environmental risk factors. Methods We identified all patients with CD included in the French hospital discharge database from 2007 to 2014. Age‐ and gender‐smoothed standardised prevalence ratios...

Objectives: Cancer patients with comorbid diabetes have a 50% increased risk of all-cause mortality compared with cancer patients without diabetes. Less attention to diabetes management (glucose control, medication adherence, and diabetes self-management behaviors) during active cancer treatment is hypothesized as an explanation for worse outcomes among diabetic cancer patients. The objective of this systematic review is to determine and quantify how a cancer diagnosis impacts diabetes management. ...

Objectives: In endometrial cancer, the appropriate sequence of adjuvant chemotherapy (aCT) and adjuvant radiation therapy (aRT) is unclear. We aim evaluated whether early chemotherapy is associated with improved overall survival (OS) and cancer-specific survival (CSS). Methods: Endometrial cancer patients that received aCT and aRT were selected from the SEER-Medicare database. Early chemotherapy was defined as receiving aCT before aRT, with or without additional aCT (“sandwich” regimens)....

Objective: Pleurex catheters are a form of palliative therapy for patients, offering relief from symptomatic ascites while also affording greater independence and flexibility; however, aggressive drainage can lead to significant total body sodium losses. We describe the course of patients with “Pleurex desalination,” an under-appreciated cause of hypovolemic hyponatremia, highlighting its unique pathophysiology and providing recommendations on how to manage these complex patients. Patients and...

Last Saturday, speech-language pathologist Summer Branch went to work as usual at the two skilled nursing facilities (SNFs) she traversed. Both West Texas facilities contract with a larger rehabilitation company, and Branch was surprised to get a call from the company’s regional manager when she clocked out of work that day. The manager told her that, as of that minute, the job she’d had for four years was terminated due to staffing changes. “I just didn’t see it coming,” Branch says. Suddenly,...

Staying on the ground: A stable sodium anode with ultra‐high specific capacity (1078 mAh g−1) is achieved by accommodating metallic sodium into a sodiophilic interphase based on oxygen‐functionalized carbon nanotube networks. The interphase renders the Na anode with a homogeneous nucleation process and a lateral plating behavior, which thermodynamically contrasts with regular vertical Na growth (dendrites). Abstract Despite efforts to stabilize sodium metal anodes and prevent dendrite formation,...

That material is dope! Graphene‐analogous particles with dual graphitic‐N doping in a six‐membered carbon ring are successfully prepared. Infrared spectroscopy, synchrotron‐based X‐ray absorption spectroscopy, and solid‐state NMR spectroscopy are applied to study its structure and mechanism in the hydrogen evolution reaction, where a current density of 10 mA cm−2 is achieved at an overpotential of 57 mV. Abstract Graphene‐based materials still exhibit poor electrocatalytic activities for the...

Enzymatic C ‐glycoside bond formation: The C‐glycoside synthases encoded in the formycin and pyrazofurin biosynthetic gene clusters are identified and compared by genomic analysis of the producing strains. Both enzymes catalyze decarboxylative C‐glycoside bond formation between phosphoribosyl pyrophosphate and a pyrazole nucleobase in reactions likely to involve electrophilic aromatic substitution. Abstract C‐Nucleosides are characterized by a C−C rather than a C−N linkage between...

Chemical approaches, in combination with mass‐ spectrometry analysis, have emerged as powerful tools to enable a broad range of biological applications. This approach is called structural proteomics. The key to success is a biocompatible reagent that modifies a protein without affecting its high‐order structure. Fluorine, well‐known to exert profound effects on the physical and chemical properties of reagents, should have an impact on structural proteomics. Here, we describe several fluorine‐containing...

Targeting, switching, and sensing were combined in one fluorescent probe to achieve the nanoscale cartography of cell plasma membranes. The proposed design is based on a new functionalization strategy of solvatochromic dye Nile Red, which is sensitive to lipid order, and a new membrane‐targeting moiety that controls binding/unbinding‐induced on/off switching for super‐resolution microscopy. Abstract Visualization of the nanoscale organization of cell membranes remains challenging because of...

While (Ph 2 CN 2 )B(C 6 F 5 ) 3 is a unstable species, single electron transfer from Cp* 2 Co affords the isolation of stable products [Cp* 2 Co][Ph 2 CNNHB(C 6 F 5 ) 3 ] 1 and [Cp*Co(C 5 Me 4 CH 2 B(C 6 F 5 ) 3 )] 2 . The analogous combination of Ph 2 CN 2 and BPh 3 showed no evidence of adduct formation and yet single electron transfer from Cp* 2 Cr affords the species [Cp* 2 Cr][PhC(C 6 H 4 )NNBPh 3 ] 3 and [Cp* 2 Cr][Ph 2 CNNHBPh 3...

Inducing uniform deposition of lithium from the stage of metal crystallization nucleation is of vital importance to achieve dendrite‐free lithium anode. Herein, using experiments and simulation, homogenization of Li nucleation and normalization of Li growth can be achieved on PNIPAM polymer brushes with lithiophilic functional groups modified Cu substrates. The lithiophilic functional groups of amide O can homogenize ion mass transfer, and induce the uniform distribution of Li nucleation sites. What’s...

Modulation of the electronic structure of metal catalysts is an effective approach to optimize the electrocatalytic activity. In this study, we discover surprisingly strong activation effects of black phosphorus (BP) on platinum (Pt) catalysts. In this way, the surface electronic structure of Pt can be effectively and rapidly modulated to produce greatly enhanced catalytic activity in the hydrogen evolution reaction (HER). The unique and negative binding energy between BP and Pt leads to spontaneous...
