Silsesquioxanes (SSQs), with the general formula, (RSiO1.5)n—where R stands for an organic group, such as alkyl, aryl, alkoxy, or H—are a type of molecular‐level organic/inorganic hybrid silica‐based material. These materials contain reactive or nonreactive organic moieties as well as inorganic Si–O–Si frameworks. In the past few years, extensive efforts have been made using SSQs to construct multifunctional nanocomposites with suitable properties for a range of applications. In this review, the recent various applications of SSQ‐containing hybrid materials are discussed, in addition to updates of the nanocomposite applications. Various physical structures and chemical reactions in SSQ‐based hybrid nanomaterials are emphasized with regard to applications in the field of polymer nanocomposites, catalysts, adsorption, sensors, and biomedicine. This review focuses on results reported in the recent five years (2013–2018). 相似文献

AIM: To investigate rates of re-establishing gastroenterology care, colonoscopy, and/or initiating me-dical therapy after Crohn’s disease(CD) surgery at a tertiary care referral center.METHODS: CD patients having small bowel or ileocolonic resections with a primary anastomosis between 2009-2012 were identified from a tertiary academic referral center. CD-specific features, medications, and surgical outcomes were abstracted from the medical record. The primary outcome measure was compliance rates with medical follow-up within 4 wk of hospital discharge and surveillance colonoscopy within 12 mo of surgery. RESULTS: Eighty-eight patients met study inclusion criteria with 92%(n = 81) of patients returning for surgical follow-up compared to only 41%(n = 36) of patients with documented gastroenterology follow-up within four-weeks of hospital discharge, P < 0.05. Factors associated with more timely postoperative medical follow-up included younger age, longer length of hospitalization, postoperative biologic use and academic center patients. In the study cohort, 75.0% of patients resumed medical therapy within 12 mo, whereas only 53.4% of patients underwent a colonoscopy within 12 mo of surgery.CONCLUSION: Our study highlights the need for coordinated CD multidisciplinary clinics and structured handoffs among providers to improve of quality of care in the postoperative setting. 相似文献

Background
Although alcohol is a leading risk factor for osteonecrosis of the femoral head (ONFH) and its prevalence reportedly ranges from 20% to 45%, there are no unified classification criteria for this subpopulation. In 2015, Association Research Circulation Osseous decided to develop classification criteria for alcohol-associated ONFH.Methods
In June of 2017, Association Research Circulation Osseous formed a task force to conduct a Delphi survey. The task force invited 28 experts in osteonecrosis/bone circulation from 8 countries. Each round of the Delphi survey included questionnaires, analysis of replies, and feedback reports to the panel. After 3 rounds of the survey, consensus was reached on the classification criteria. The response rates for the 3 Delphi rounds were 100% (round 1), 96% (round 2), and 100% (round 3).Results
The consensus on the classification criteria of alcohol-associated ONFH included the following: (1) patients should have a history of alcohol intake >400 mL/wk (320 g/wk, any type of alcoholic beverage) of pure ethanol for more than 6 months; (2) ONFH should be diagnosed within 1 year after alcohol intake of this dose; and (3) patients should not have other risk factor(s).Conclusion
ARCO-established classification criteria to standardize clinical studies concerning AA-ONFH. 相似文献127.

Acne is a chronic inflammatory disease of the pilocebaceous unit that presents with various spectrum and severity. Genetic backgrounds and environmental factors are also considered to be relevant, but few studies have focused on Korean patients. A cross‐sectional epidemiologic study on family history of Korean acne patients was performed to analyze family history of acne, and to compare the severity and characteristics of acne in association with family history. A total of 221 patients were enrolled, 98 male (44.3%) and 123 female (55.7%). Patients were grouped as patients with (A+) or without (A‐) family history of acne. In a second analysis, patients with any experience of acne treatment were evaluated. Severity of acne was measured with Burton's grading system and Korean Acne Grading System (KAGS). Female patients had a higher tendency to have family history than males (P = 0.002). Group A+ had statistically significant earlier onset of acne (P = 0.002). In inexperienced patients, patients with family history showed a relatively earlier onset (P = 0.084). This study confirmed the role of heredity in acne. Family history of acne is associated with earlier onset of the disease, and more non‐inflammatory lesions. 相似文献

A new class of photorefractive (PR) composite based on a fully functionalized polymer with high phase‐stability is reported. The polymer containing non‐linear optical (NLO) chromophores and charge‐transporting carbazole moieties is synthesized by a polymer‐analogous reaction. The polymer is doped with plasticizer, NLO dye, and sensitizer to fabricate the PR composite. The NLO dye is the same as the NLO chromophore moiety in the polymer side chain. The PR performance of the composite is evaluated by degenerated four‐wave mixing and two‐beam coupling measurements. A diffraction efficiency of 30% at a relatively low applied electric field of 45 V μm?1 is achieved. Despite a high concentration of NLO dye, the composites show good stability for a long period without phase separation. 相似文献
