A G Franke et al, 2014. The Use of Caffeinated Substances by Surgeons for Cognitive Enhancement, Annals of Surgery, published online ahead of print.

OBJECTIVE: To investigate the use of coffee, caffeinated drinks, and caffeine tablets for pharmacological cognitive enhancement (CE) among surgeons.

BACKGROUND: Surgeons have demanding workloads, and the resulting fatigue and concentration deficits can lead to medical errors. Some surgeons use substances that promote wakefulness to counteract these effects.

METHODS: A total of 3306 surgeons who attended 5 international conferences in 2011 were surveyed regarding their use of coffee, caffeinated drinks, and caffeine tablets for CE and potential factors derived from professional and private life using an anonymous self-report questionnaire. In this study, we were only interested in surgeons working in hospitals; therefore, 951 questionnaires were statistically analyzed.

RESULTS: The most prevalent reason for using caffeine of any kind was to reduce fatigue (54.3%). Further prevalent reasons are working the night shift (32.2%) and overly long and excessive work hours (31.7%). Lifetime, past-year, past-month, and past-week prevalence was 66.8%, 61.9%, 56.9%, and 50.5%, for coffee use; 24.2%, 15.4%, 9.9%, and 6.1%, for caffeinated drinks; and 12.6%, 5.9%, 4.7%, and 3.8%, respectively, for caffeine tablets. Caffeine use was associated with lower age, male gender, divorced marital status, living with children, lack of satisfaction with professional status, pressure to perform in private life, and pressure perceived to be harmful to one’s own health.

CONCLUSIONS: Surgeons often use caffeinated substances to cope with fatigue and long working hours. Coffee use was more prevalent than the use of caffeinated drinks and caffeine tablets.

Made in the USA: The State of the Hawaiian Coffee Industry

by Roast Magazine Editor Emily Puro When you think Kona, you probably think coffee. In many ways, it’s that rich reputation and long-standing tradition that make Hawaii’s coffee professionals so passionate, though you’ll find passion for exceptional coffee not just in Kona but throughout the state — on Kauai, Maui, Oahu, Molokai and other islands, and in the other growing […]

Drama Unfolds with the Opening of Williamsburg’s First Starbucks

As might be expected, there has been some pushback related to the opening of Williamsburg’s first Starbucks, which debuted at 6 a.m. today at the new 65 Ainsle building at the intersection of Ainsle and Union. If Williamsburg didn’t “officially end” in November with the opening of a Dunkin’ Donuts, Eater says the Starbucks opening makes “the gentrification of hipsterville” complete. […]

G Rojo-Martiez et al, 2014. Serum sCD163 Levels are Associated with Type 2 Diabetes Mellitus and Are Influenced by Coffee and Wine Consumption: Results of the Di@bet.es Study, PLOS One, published online.

Serum levels of soluble TNF-like weak inducer of apoptosis (sTWEAK) and its scavenger receptor CD163 (sCD163) have been linked to insulin resistance. We analysed the usefulness of these cytokines as biomarkers of type 2 diabetes in a Spanish cohort, together with their relationship to food consumption in the setting of the Di@bet.es study.

RESEARCH DESIGN AND METHODS: This is a cross-sectional, matched case-control study of 514 type 2 diabetes subjects and 517 controls with a Normal Oral Glucose Tolerance Test (NOGTT), using data from the Di@bet.es study. Study variables included clinical and demographic structured survey, food frequency questionnaire and physical examination. Serum concentrations of sTWEAK and sCD163 were measured by ELISA. Linear regression analysis determined which variables were related to sTWEAK and sCD163 levels. Logistic regression analysis was used to estimate odd ratios of presenting type 2 diabetes.

RESULTS: sCD163 concentrations and sCD163/sTWEAK ratio were 11.0% and 15.0% higher, respectively, (P<0.001) in type 2 diabetes than in controls. Following adjustment for various confounders, the OR for presenting type 2 diabetes in subjects in the highest vs the lowest tertile of sCD163 was [(OR), 2,01 (95%CI, 1,46-2,97); P for trend <0.001]. Coffee and red wine consumption was negatively associated with serum levels of sCD163 (P = 0.0001 and; P = 0.002 for coffee and red wine intake, respectively).

CONCLUSIONS: High circulating levels of sCD163 are associated with type 2 diabetes in the Spanish population. The association between coffee and red wine intake and these biomarkers deserves further study to confirm its potential role in type 2 diabetes.


M S H Akash et al, 2014. Effects of coffee on type 2 diabetes mellitus. Nutrition, published online ahead of print.

This review provides the epidemiologic and research evidences documenting the effects of coffee consumption on type 2 diabetes mellitus (T2DM). We summarize the literature concerning the effects of coffee consumption on different mechanistic factors involving in pathogenesis of T2DM, such as glucose tolerance, insulin sensitivity, insulin resistance, glucose-6-phosphatase, intestinal glucose absorption, antioxidant activity, inflammatory biomarkers, nuclear factor-κB inhibition, glucose uptake, glucose homeostasis, glucose metabolism, and insulin secretion. These factors play a crucial role in influencing the normal levels of glucose in blood. Overall, the experimental and epidemiologic evidences presented here elucidate the protective effects of coffee consumption on T2DM, involving multiple preventive mechanisms. Despite the firm evidences available through a growing literature base, it is still uncertain whether the use of coffee should be recommended to patients with diabetes and/or any patient who might be at the risk of T2DM as a supplementary therapy to prevent further progression of T2DM.

You’ll Probably Rush to Ebay for Vintage Hot Plates After Seeing this FrankenMoka

Amsterdam-based Frans Goddijn is one of specialty coffee’s mad scientists. Most recently, he’s shared with us his camera work capturing transparent portafilters to monitor puck behavior during extraction. Now Goddijn gives us his latest FrankenCoffee project: A decked out moka pot that he says results in a sweet espresso-like brew, including a touch of crema. “With a moka pot?” you ask. “Yes,” we say, […]

Pod Giant Nestle Nespresso Turns to College Students for Sustainability Advice

For the second year running, Nestlé Nespresso has looked to the academic business world for ideas to fold into the Swiss mega-roaster and pod-maker’s sustainability plans. Sustainability in the single-serve pod segment is arguably an oxymoronic concept, but if nothing else, the second annual Nespresso MBA Challenge gives the coffee world a fresh perspective on how some of the brightest minds in business […]
