ReviewFraud and retraction in perioperative medicine publications: what we learned and what can be implemented to prevent future recurrence.
90% of fraudulent papers in perioperative medicine retracted over the last 30 years were authored by only six researchers.

Multicenter Study
Regional and institutional variation in the initiation of early do-not-resuscitate orders.
Do-not-resuscitate (DNR) orders are an important step in decision making about aggressiveness of care for patients in hospitals. The use of DNR orders is known to vary with patient characteristics, but few studies have investigated the role of hospital factors or of regional variation. We examined these influences on the use of early DNR orders (written <24 hours after admission). ⋯ Hospital characteristics appear to be associated with the use of DNR orders, even after accounting for differences in patient characteristics. This association reflects institutional culture, technological bent, and physician practice patterns. If these factors do not match patient preferences, then improvements in care are needed.

Dum-dums, hollow-points, and devastators: techniques designed to increase wounding potential of bullets.
When considering the kinetic energy formula (KE = 1/2 MV2) to estimate wounding potential of bullets, bullet velocity has assumed the premier role as the determinant of wounding capability. Particular characteristics of the bullet such as mass have assumed positions of secondary importance or have been largely ignored. ⋯ Dum-dum bullets, hollow-points, shot shells, and explosive bullets have been designed so as to cause delivery of greater kinetic energy to the victim. Surgeons managing gunshot wounds must be familiar with these types of bullets in order to properly care for the victims and to ensure their own safety during the process.

Review
Prevalence of multiple micronutrient deficiencies amongst pregnant women in a rural area of Haryana.
Deficiencies of micronutrients (zinc, iron, folic acid and iodine) during pregnancy are known causes of Low Birth Weight (LBW). Studies have documented status of one or two micronutrients amongst pregnant women (PW). However, no attempt has been made to concurrently assess the prevalence of multiple micronutrient deficiencies and the factors associated with them amongst PW. ⋯ There was a high prevalence of micronutrient deficiencies amongst the PW of the area, possibly due to the poor dietary intake of food and low frequency of consumption of food groups rich in micronutrients. The concurrent prevalence of two, three, four and five micronutrient deficiencies were common.

Multicenter StudyPercutaneous Transvenous Transseptal Transcatheter Valve Implantation in Failed Bioprosthetic Mitral Valves, Ring Annuloplasty, and Severe Mitral Annular Calcification.
This study sought to examine the feasibility, safety, and intermediate-term outcomes in patients undergoing percutaneous transvenous transcatheter mitral valve implantation in failed bioprosthesis, ring annuloplasty, and calcific mitral stenosis. ⋯ Transfemoral percutaneous transvenous mitral valve implantation in high-risk patients with degenerated bioprosthesis is safe, effective, and associated with rapid improvement in hemodynamics, short length of stays, and improved functional status. Percutaneous mitral valve implantation in patients with failed annuloplasty rings and severe MAC is a promising therapy with significant short-term morbidity and mortality that requires further study.
