Smoke low-tar cigarettes? The fatal flaw in logic of nutritional studies
Just because something bad is reduced or eliminated in cigarettes, it should not logically follow that cigarettes must now be good, right? Low-tar, filtered cigarettes may be less harmful than full-tar, unfiltered cigarettes, but still contain heavy metals like mercury, lead, and cadmium, as well as nicotine, naphthalene, arsenic, formaldehyde, ammonia and other toxic compounds. Low- or no-tar does NOT mean healthy. This may seem obvious, but it is surprising how many people—physicians and dietitians included—fall for such flawed logic when applied to nutrition. We saw this play out in yet another flawed analysis released from the U.K. this week with media headlines proclaiming “Whole grains lengthen life” and the like. This was not a new study, but a re-analysis of prior studies (a “meta-analysis”). In each and every study included in this analysis, increasing consumption of whole grains (usually in quartiles or quintiles of whole grain intake) was compared to consumption of white flour products, and there are indeed benefits (not due to B vitamins nor cellulose fiber, but due to the arabinoxylan and amylose prebiotic fiber content): longer life, less type 2 diabetes, less cardiovascular disease, less weight gain (not weight LOSS)—that is all true. In other words, if we conducted a study that compared increasing reliance on low-tar filtered cigarettes with smoking full-tar unfiltered cigarettes and demonstrated, say, a 27% reduction ...

Saima Herz, 30, woke up one morning feeling feverish with a throbbing headache before she went to her GP and was told she'd picked up a virus.
TYPE 2 diabetes is a chronic condition that requires a person to overhaul aspects of their lifestyle to keep rising blood sugar levels in check. Diet plays a decisive role in regulating blood sugar and warding off the threat of developing serious conditions and evidence is increasingly singling out certain items for their blood sugar-lowering benefits, including a certain fruit.

BACKGROUND: In 2016, the American Society of Colon and Rectal Surgeons published a rectal cancer surgery checklist composed of the essential elements of preoperative, intraoperative, and postoperative care for patients undergoing rectal cancer surgery. OBJECTIVE: The purpose of this study was to assess whether compliance with preoperative checklist elements was associated with improved pathologic and 30-day postoperative outcomes after rectal cancer surgery. DESIGN: This was a retrospective cohort study. SETTINGS: The study involved North American hospitals contributing to the American College of Surgeons Nation...
CONCLUSIONS: The residual disease rate in patients treated surgically was higher than previously reported (43.2%). Incidence of recurrence in patients treated conservatively was low (4.4%). Areas of improvements have been identified in adherence to endoscopic follow-up, histopathological reporting, and potential overuse of radiological surveillance.
