Associations of Early Age of First Intoxication with Past Year Drinking Contexts and Problems

Background: Mechanisms underlying associations between early drinking and problems are largely unknown. Objectives: We investigated (a) associations between early age of first intoxication (≤15?years) and past year drinking in different contexts and (b) whether early age of first intoxication is differentially associated with problems in these contexts. Methods: We used survey data collected in 2013–2014 from 405 past-year adolescent drinkers in 24 midsized California cities. Data included demographics; drinking behaviors; age of first intoxication; frequency of being at and drinking at restaurants, bars/nightclubs, outdoor places, and home; and problems. We used multilevel logistic and negative binomial models to account for the clustering of adolescents within cities. Probabilities were corrected to maintain family-wise error rates. Results: Early age of first intoxication was associated with a 120% increase in the odds of drinking at outdoor settings (OR = 2.20, p_c < .05). Early age of first intoxication was associated with increased numbers of problems related to drinking in restaurants (IRR = 5.72, p_c < .001), outdoor settings (IRR = 3.40, p_c < .001), and homes (IRR = 2.84, p_c < .001). Later intoxication (≥16?years) was not significantly associated with increased drinking or problems in any of these contexts. Conclusions: Results suggest that underage drinkers who report early intoxication are more likely to drink at outdoor settings, but not other contexts. However, they may differentially experience drinking problems across contexts. To target youths who have experienced intoxication at an early age and to reduce problems, prevention interventions should focus on outdoor settings.     

Barriers to the use of patient safety information sources by community pharmacies

BackgroundWhen patient safety information is communicated across a regulatory jurisdiction or country, the potential to enhance the safety of community pharmacy practice is significant. While there currently exists a number of sources for patient safety information (e.g., websites, safety bulletins, online tools), knowledge of the barriers that may inhibit the use of such information sources within community pharmacies is limited.ObjectiveThis research explores community pharmacy manager use of Canadian patient safety information sources and the barriers that may limit the use of such sources.MethodsA qualitative research study design using semi-structured interviews was conducted with 15 community pharmacy managers in the Halifax Regional Municipality of Nova Scotia, Canada. The study explored how pharmacists access and engage a variety of information sources, including corporate intranets, websites, and tools provided by third party data base repositories. Interview data were analyzed using thematic analysis.ResultsFive general barriers were identified: lack of time to access information sources and its contents; too many sources of available information; too much information not relevant to community pharmacy practice; complexity navigating online information sources; and lack of community pharmacy involvement in source design.ConclusionWhile pharmacies do use safety information sources to enhance practice safety, their ability to incorporate this information is inhibited by their general lack of time available to access and read safety information, lack of knowledge about where to get this information, and lack of tailored information for the community pharmacy context. Future initiatives should address increasing information awareness of available sources, consolidating and reducing information overload of such sources, and packaging information to better fit with pharmacists’ needs.     

自身免疫性胰腺炎的诊断

自身免疫性胰腺炎（AIP）是一类特殊的慢性胰腺炎，其临床上依据组织学分为Ⅰ型和Ⅱ型。我国以Ⅰ型为主，是 IgG4相关性疾病的一部分，常表现为梗阻性黄疸或胰腺实质的肿块。组织学上表现为病变组织大量淋巴浆细胞的浸润及慢性纤维化。虽然国际胰腺病协会围绕其影像学、血清学、组织学及激素治疗的反应制定了诊断标准，但 AIP的临床表现较为隐匿和多样，其诊断仍然具有挑战性，特别是表现为胰腺肿块的患者，需要时刻警惕胰腺癌的风险。本文从影像学、组织学角度对文献进行了概述，重点是这种复杂疾病的诊断及误诊的风险，以期提高本病的鉴别诊断水平。

Background

Very little is known about long-term valve durability after transcatheter aortic valve replacement (TAVR).

玻璃体切割联合内界膜剥除治疗糖尿病性黄斑水肿

评估玻璃体切割联合内界膜剥除对糖尿病性黄斑水肿（DME）的疗效。方法：回顾性病例对照研究。2014年6月至2017年1月间因糖尿病视网膜病变合并玻璃体积血或增殖病变于温州医科大学附属眼视光医院杭州院区行玻璃体切割手术治疗，且术前或术中经光学相干断层扫描（OCT）检查确诊合并DME的患者31例（33眼）纳入研究。16例（18眼）术中联合内界膜剥除作为剥膜组，15例（15眼）仅接受玻璃体切割手术治疗者作为对照组。所有手术均由同一医师主刀完成。术后1、3个月随访时复查OCT，对比观察黄斑中心厚度（CMT）和视力的术后变化情况。随访中CMT和最佳矫正视力（BCVA）比较采用重复测量方差分析，组间CMT和BCVA比较采用独立样本t检验。结果：手术前，手术后1、3个月2组间比较LogMAR视力总体差异有统计学意义（F=15.93，P<0.001）。术后 1个月时剥膜组BCVA高于对照组（t=2.55，P=0.02），但术后3个月时2组间差异无统计学意义（t=0.82， P=0.42）。手术前，手术后1、3个月CMT总体差异无统计学意义（F=2.85，P=0.065）。术后1、3个月时，剥膜组的CMT均低于对照组，2组间差异均有统计学意义（t=2.24，P=0.03；t=3.79，P=0.001）。术后1个月时，剥膜组有效（与术前比CMT减少20%以上）、无效（变化不超过20%）及恶化（增厚超过 20%）的例数分别为8、6、4例，术后3个月时则分别为11、5、2例，与对照组相比，术后1个月时组间差异无统计学意义（Z=-1.687，P=0.092），术后3个月时剥膜组DME改善有效比例明显高于对照组，组间差异有统计学意义（Z=-2.177，P=0.029）。结论：对于非牵拉性DME，内界膜剥除有助于术后早期DME消退。     

Role of OCT Angiography in the Detection of Retinal Vascular and Macular Abnormalities in Subjects with Asteroid Hyalosis

Purpose: To study the role of Optical coherence tomography (OCT) Angiography (OCTA) in detecting retinal vascular and macular abnormalities as compared to Fundus Fluorescein Angiography (FFA) in subjects with Asteroid hyalosis (AH).

Methods: In a prospective study, patients with AH underwent OCTA and FFA. AH graded as Grade 1 in 8 (optic disc, second order vessels visible), Grade 2 in 4 (optic disc, first-order vessels visible), Grade 3 in 11 (hazy view of optic disc) and Grade 4 (no view of fundus) in 2 eyes.

Results: A total of 20 patients (25 eyes) with AH were included. In comparison to FFA, OCTA was able to similarly detect Diabetic Retinopathy changes such as Neovascularization, microaneurysms, capillary dropout, and foveal avascular zone extent in vascular occlusion in all grades of AH.

Conclusion: OCTA, a noninvasive imaging tool, could detect various retinal vascular and macular abnormalities in patients with all grades of AH in comparison to FFA.
