Change in Patient-Reported Outcomes in Single-Unit Transfusion Comparable with Double-Unit Transfusion
Blood

2016Patient blood management was developed to reduce allogeneic blood exposure and enhance patient outcomes. If transfusion is required in stable and non-bleeding hospitalized patients, prescribing one unit of red blood cells (RBC) followed by reassessment of clinical condition is recommended. Double-unit RBC transfusion, the routine practice in the past, is still widely practiced despite the advocate of restrictive transfusion strategy. One of the reasons could be a lack of evidence to support the optimal number of RBC units per transfusion. Blood transfusion is often performed to alleviate anemic symptoms. However, patient-reported outcomes were seldom measured to evaluate transfusion requirements.

A Foodborne Outbreak of Gastroenteritis Caused by Vibrio parahaemolyticus and Norovirus through Non-Seafood Vehicle
PloS one

2015Foodborne outbreaks caused by a mixed infection of Vibrio parahaemolyticus and norovirus have rarely been described. We reported a mixed outbreak of Vibrio parahaemolyticus and norovirus causing acute gastroenteritis in 99 staff members of a company in Guangdong, China, in May 2013, following consumption of roasted duck, an uncommon non-seafood vehicle for such mixed infection, in one meal served in the company's catering service. Epidemiological and laboratory findings indicated that a single asymptomatic food handler was the source of both pathogens, and the high rate of infection of both pathogens was exacerbated by the setting’s suboptimal food hygiene practice.

Immune Responses to Twice-Annual Influenza Vaccination in Older Adults in Hong Kong.
Clinical Infectious Diseases

Many health authorities recommend influenza vaccination of older adults to reduce disease burden. We hypothesized that in tropical and subtropical areas with more prolonged influenza seasons, twice-annual influenza vaccination might provide older adults with improved immunity against influenza.
