Risk of latent and active tuberculosis infection in travellers: a systematic review and meta-analysis.

Introduction: Achieving tuberculosis (TB) elimination in low TB incidence countries requires identification and treatment of individuals at risk for latent TB infection (LTBI). Persons travelling to high TB incidence countries are potentially at risk for TB exposure. This systematic review and meta-analysis estimates incident LTBI and active TB among individuals travelling from low to higher TB incidence countries.

Severe maternal morbidity surveillance: Monitoring pregnant women at high risk for prolonged hospitalisation and death.

Background: There is no international consensus on the definition and components of severe maternal morbidity (SMM).

Objectives: To propose a comprehensive definition of SMM, to create an empirically justified list of SMM types and subtypes, and to use this to examine SMM in Canada.

Methods: Severe maternal morbidity was defined as a set of heterogeneous maternal conditions known to be associated with severe illness and with prolonged hospitalisation or high case fatality.

Severe Maternal Morbidity in Canada: Temporal Trends and Regional Variations, 2003-2016.

Objective: This study sought to quantify temporal trends and provincial and territorial variations in severe maternal morbidity (SMM) in Canada.

Methods: The study used data on all hospital deliveries in Canada (excluding Québec) from 2003 to 2016 to examine temporal trends and from 2012 to 2016 to study regional variations. SMM was identified using diagnosis and intervention codes.

Prevalence of Severe Maternal Morbidity and Factors Associated With Maternal Mortality in Ontario, Canada.

Importance: Severe maternal morbidity is defined by potentially life-threatening conditions. The association between the number of severe maternal morbidity (SMM) indicators and maternal death is not known.

Objective: To quantify the association between the number of SMM indicators and maternal mortality.
