Importance: Guidelines recommend augmenting enteral protein during critical illness, but the impact on patient outcomes is uncertain.

Objective: To determine whether augmenting enteral protein increases days alive and free from hospitalization.

Background: The Augmented versus Routine Approach to Giving Energy Trial (TARGET) was a 4000-patient trial in which augmented enteral calorie dose did not influence outcomes.

Aim: We aimed to quantify practice change following TARGET.

Methods: Three single-day, prospective, multicentre, point-prevalence audits of adult patients receiving enteral nutrition (EN) in participating Australian and New Zealand intensive care units at 10:00 AM were conducted: (i) 2010 (before conducting TARGET); (ii) 2018 (immediately before publishing TARGET results); and (iii) 2020 (2 years after TARGET publication).

Article Synopsis
  • The study evaluates the effectiveness of ROTEM sigma, a point-of-care coagulation test, in assessing coagulation in patients with isolated traumatic brain injuries (TBI) compared to traditional lab tests.
  • Out of 36 patients tested, 22% exhibited a hypocoagulable state, which correlated with a higher death rate from head injuries, indicating the prognostic value of ROTEM sigma.
  • ROTEM tests provided faster results than standard tests, demonstrating that ROTEM parameters can quickly and accurately predict the risk of head injury-related death.

Tuberculosis (TB) is the leading cause of death among persons with HIV. In 2022, an estimated 167,000 TB-related deaths occurred globally among persons with HIV. TB preventive treatment (TPT) helps prevent TB disease and is recommended for persons at high risk for developing TB, including those with HIV.

To quantify current protein prescription and delivery in critically ill adults in Australia and New Zealand and compare it with international guidelines. Prospective, multicentre, observational study. Five intensive care units (ICUs) across Australia and New Zealand.

Article Synopsis
  • The TARGET Protein trial will assess whether increasing dietary protein intake in ICU patients, as recommended by international guidelines, leads to better health outcomes compared to current practices.
  • This clinical trial involves eight ICUs in Australia and New Zealand, where each ICU will switch between two different enteral nutrition formulas over a period of 12 months.
  • The main goal is to see if higher protein intake reduces the number of days patients spend in the hospital and improves survival rates at 90 days post-admission.

Background: Nutritional needs of trauma patients admitted to the intensive care unit may differ from general critically ill patients, but most current evidence is based on large clinical trials recruiting mixed populations.

Objective: The aim of the study was to investigate nutrition practices at two time points that span a decade in trauma patients with and without head injury.

Methods: This observational study recruited adult trauma patients receiving mechanical ventilation and artificial nutrition from a single-centre intensive care unit between February 2005 to December 2006 (cohort 1), and December 2018 to September 2020 (cohort 2).

Introduction: A strategic framework for 2021-2030 developed by the World Health Organization (WHO) Regional Office for the Western Pacific emphasizes the need for high-quality and integrated vaccine-preventable disease (VPD) surveillance. We conducted a literature review to document the barriers, enabling factors, and innovations for integrating surveillance functions for VPDs and other communicable diseases in Western Pacific Region (WPR) countries.

Methods: We searched published and gray literature on integrated VPD surveillance from 2000 to 2021.

Background: Traditionally, surgical drains are considered a relative contraindication to telemedicine-based postoperative care. We sought to assess the safety, feasibility, and outcomes of an at-home patient-performed surgical drain removal pilot program.

Methods: A prospective cohort study among patients who were discharged with surgical drains was performed.

Article Synopsis
  • * A study found that while many convalescents maintain certain antibodies and memory B cells after 12 months, their ability to neutralize newer variants, particularly Omicron, is severely weakened.
  • * Although more than half of the subjects retain memory T cells from their initial infection, these cells show reduced effectiveness against mutations found in newer variants, highlighting the need for vaccination to enhance protection against re-infection.

Data collected through routine syndromic surveillance for influenza-like illness in the Micronesian United States-affiliated Pacific Islands highlighted out-of-season influenza outbreaks in the spring of 2019. This report describes the data collected through the World Health Organization's Pacific Syndromic Surveillance System for the Commonwealth of the Northern Mariana Islands (CNMI), Guam, the Federated States of Micronesia (FSM) and the Republic of the Marshall Islands (RMI). Compared with historical data, more cases of influenza-like illness were observed in all four islands described here, with the highest number reported in Guam in week 9, CNMI and FSM in week 15, and RMI in week 19.

Background: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a highly infectious respiratory virus which is responsible for the coronavirus disease 2019 (COVID-19) pandemic. It is increasingly clear that recovered individuals, even those who had mild COVID-19, can suffer from persistent symptoms for many months after infection, a condition referred to as "long COVID", post-acute sequelae of COVID-19 (PASC), post-acute COVID-19 syndrome, or post COVID-19 condition. However, despite the plethora of research on COVID-19, relatively little is known about the molecular underpinnings of these long-term effects.

Background: Energy-dense formulae are often provided to critically ill patients with enteral feed intolerance with the aim of increasing energy delivery, yet the effect on gastric emptying is unknown. The rate of gastric emptying of a standard compared with an energy-dense formula was quantified in critically ill patients.

Methods: Mechanically ventilated adults were randomized to receive radiolabeled intragastric infusions of 200 mL standard (1 kcal/mL) or 100 mL energy-dense (2 kcal/mL) enteral formulae on consecutive days in this noninferiority, blinded, crossover trial.

Background: International guidelines recommend critically ill adults receive more protein than most receive. We aimed to establish the feasibility of a trial to evaluate whether feeding protein to international recommendations would improve outcomes, in which 1 group received protein doses representative of international guideline recommendations (high protein) and the other received doses similar to usual practice.

Methods: We conducted a prospective, randomized, blinded, parallel-group, feasibility trial across 6 intensive care units.

The long-term effects of delivering approximately 100% of recommended calorie intake via the enteral route during critical illness compared with a lesser amount of calories are unknown. Our hypotheses were that achieving approximately 100% of recommended calorie intake during critical illness would increase quality-of-life scores, return to work, and key life activities and reduce death and disability 6 months later. We conducted a multicenter, blinded, parallel group, randomized clinical trial, with 3,957 mechanically ventilated critically ill adults allocated to energy-dense (1.
