PURPOSES: Since 2016, the World Health Organization has recommended universal antiretroviral therapy (ART) for all people living with Human Immunodeficiency Virus (PLHIV). This recommendation may have influenced the characteristics and outcomes of PLHIV admitted to the Intensive Care Unit (ICU). This study aims to identify changes in the epidemiological and clinical characteristics of PLHIV admitted to the ICU, and their short- and medium-term outcomes before and after the implementation of universal ART (periods 2006-2015 and 2016-2019)...

PURPOSE: COVID-19 and influenza infections have similar modes of transmission and clinical symptoms but have different prognoses and treatment methods; therefore, it is important to make a final diagnosis. Herein, we aimed to compare the demographic, clinical, and laboratory differences in hospitalized pediatric patients with COVID-19 and influenza. METHODS: This retrospective study comprised patients with COVID-19 managed between March 2020 to February 2022, and patients with influenza managed between December 2017 to February 2022, at a tertiary care hospital...

BACKGROUND AND AIMS: Pneumoperitoneum creation for laparoscopic surgery increases the intraabdominal pressure and causes alveolar atelectasis. We investigated the influence of an increase in intra-abdominal pressure (IAP) on ventilatory mechanical power (MP) delivery during pneumoperitoneum creation for laparoscopic cholecystectomy. MATERIAL AND METHODS: In a prospective cohort design, we enrolled 42 patients undergoing laparoscopic cholecystectomy. During pneumoperitoneum creation, the IAP was sequentially raised to three predefined IAP levels (8, 11 and 14 mmHg), keeping identical ventilatory settings (timepoints T1, T2, and T3)...

Bronchial rupture following major blunt chest trauma should be suspected in any case of massive and persistent air leak through the intercostal drain tube. Chest radiographs and chest computed tomography scans (CT scans) are highly suggestive of this extremely rare tracheobronchial injury. The present study reported a patient who was a 15-year-old boy. He was a case of a motor-car accident and was brought to the emergency room (ER) of Rajaie Hospital ( Shiraz, Iran) due to dyspnea and chest pain. The physical examination revealed a few crash injuries on his upper extremities, as well as subcutaneous emphysema in his neck...

Fiberoptic bronchoscopy (FBO) has diagnostic or therapeutic purposes but can cause respiratory deterioration, particularly in patients with pre-existing acute respiratory failure (ARF). Non-invasive ventilation (NIV) and high-flow nasal cannula oxygen therapy (HFNC) are used as respiratory support for ARF as well as to prevent significant oxygen deterioration during FBO. The combined use of NIV and early therapeutic FBO to clear retained abundant infected secretions from the airways may be an alternative to intubation and invasive mechanical ventilation (IMV), but no data exist on the combined use of FBO and HFNC...

BACKGROUND: Extubation failure (EF) is common in the intensive care unit (ICU) and is associated with poor prognosis, especially in high-risk patients. However, the efficacy of prophylactic noninvasive oxygen therapy (NIT), including noninvasive ventilation (NIV) and high-flow nasal cannula (HFNC), in reducing EF in high-risk patients remains controversial. Therefore, we aimed to evaluate the effect of post-extubation prophylactic NIT on EF in high-risk patients. METHODS: This was a retrospective observational study conducted in the ICU from March 2018 to December 2023...

OBJECTIVE: The aim of this study was to investigate sex-related differences in the clinical characteristics and hospital outcomes of patients undergoing surgery for acute type A aortic dissection (AAAD). METHODS: This study was a retrospective study. Patients who underwent surgery for AAAD at the Department of Cardiac Surgery, Fujian Medical University Union Hospital, from January 2014 to March 2023 were consecutively included. Data was extracted from electronic medical records...

BACKGROUND: Extracorporeal membrane oxygenation (ECMO) is increasingly employed to support lung function in patients with acute respiratory failure (ARF). However, the long-term outcomes of the approach have not been encouraging when compared to those of conventional mechanical ventilation. Further, the long-term effects of ECMO on lung function and recovery are unclear. For this review, we examined the long-term lung function outcomes of patients with ARF treated with and without ECMO...

Intravenous immunoglobulin (IVIG) is an immunomodulatory therapy that has been studied in several neuroimmune conditions, such as Guillain-Barré Syndrome, chronic inflammatory demyelinating polyneuropathy, multifocal motor neuropathy, and multiple sclerosis. It has also been proposed as a potential treatment option for acute COVID-19 infection and post-acute sequelae of SARS-CoV-2 infection (PASC). IVIG is thought to function by providing the recipient with a pool of antibodies, which can, in turn, modulate immune responses through multiple mechanisms including neutralization of cytokines and autoantibodies, saturation of neonatal fragment crystallizable receptors, inhibition of complement activation, and regulation of T and B cell mediated inflammation...

RATIONALE: Due to effects of aging on the respiratory system, it is conceivable that the association between driving pressure and mortality depends on age. OBJECTIVE: We endeavored to evaluate whether the association between driving pressure and mortality of patients with acute respiratory distress syndrome (ARDS) varies across the adult lifespan, hypothesizing that it is stronger in older, including very old (≥80 years), patients. METHODS: We performed a secondary analysis of individual patient-level data from seven ARDS Network and PETAL Network randomized controlled trials ("ARDSNet cohort")...

Most approaches to advance simplified physiology-based precision medicine strategies for obstructive sleep apnea (OSA) focus on sleep parameters (i.e., OSA endotypes). However, wakefulness physiology measures can also provide prediction insight for certain OSA therapies yet their relationship with sleep parameters has not been extensively investigated. This study aimed to investigate potential relationships between awake ventilatory control parameters and sleep OSA endotypes and their potential to predict changes in OSA severity with morphine...

BACKGROUND: Hospital-acquired pressure ulcer (HAPU) is a significant problem in healthcare settings and is associated with negative impacts on patient health. Although monitoring of pressure ulcers (PUs) among hospitalised patients was started more than a decade ago in Oman, no previous studies have been completed to estimate the prevalence and risk factors of HAPUs among patients in the intensive care unit (ICU). The aim of this study was to estimate the prevalence and identify risk factors for HAPUs among adult ICU patients in selected tertiary hospitals in Oman...

Caregivers of children with medical complexity face daily tasks comparable to pediatric critical care nursing with multiple stressors. This may result in emotional and spiritual distress. Caregivers may also rely on their religion and spirituality to cope. Chaplains have the potential to support caregivers in this setting, beginning with spiritual assessment. This study's purpose was to verify the feasibility and acceptability of the Spiritual Care Assessment and Intervention framework adapted for home-based chaplaincy with caregivers of children receiving home mechanical ventilation (SCAI-Peds)...

OBJECTIVES: This study seeks to determine the overall and post-intensive care unit (ICU) length of stay (LOS) for children with tracheostomies and chronic mechanical ventilation. We hypothesized that medical and social factors would be associated with prolonged LOS. STUDY DESIGN: This single-center retrospective review included children who were discharged after initiation of chronic ventilation via tracheostomy over an 8-year period (2015-2022). Patients were divided into two groups for analysis, those who had been previously home before admission (HBA) and those who had not (Not HBA)...

BACKGROUND: Emerging evidence describes the high incidence and strong impact of hyperglycemia on the outcomes of critically ill patients with a diagnosis of COVID-19. Given resource limitations during the COVID-19 pandemic, clinicians moved away from using continuous IV infusions of insulin to manage hyperglycemia. OBJECTIVE: To evaluate glycemic control in critically ill patients receiving various medication regimens to manage their hyperglycemia. METHODS: This retrospective cohort study involved 120 mechanically ventilated adult patients (> 18 years) with COVID-19 who were admitted to the intensive care unit (ICU) between February 2020 and December 2021...

INTRODUCTION: Modified Blalock-Taussig shunt (BT shunt) is a palliative operation used for cyanotic heart diseases with decreased pulmonary blood supply. The definitive management of tetralogy of Fallot (TOF) is total corrective surgery, but these patients can be palliated with BT shunt. In the modern world, the BT shunt is getting out of favour in patients with TOF. In this article, we will share our 5-year experience at our institute, which also shows a decreasing trend. PATIENTS AND METHODS: It is a retrospective study...

BACKGROUND: Sleep deprivation is common in intensive care units (ICUs) and may alter respiratory performance. Few studies have assessed the role of sleep disturbances on outcomes in critically ill patients. OBJECTIVES: We hypothesized that sleep disturbances may be associated with poor outcomes in ICUs. METHODS: Post-hoc analysis pooling three observational studies assessing sleep by complete polysomnography in 131 conscious and non-sedated patients included at different times of their ICU stay...

BACKGROUND: Large variations in respiratory system compliance and resistance may cause the accuracy of tidal volume (VT) delivery beyond the declared range. This study aimed at evaluating the accuracy of VT delivery using a test lung model to simulate pulmonary mechanics under normal or disease conditions. METHODS: In vitro assessment of the VT delivery accuracy was carried out on two commercial ventilators. Measurements of the inspired and expired VT from the ventilator and FlowAnalyser were compared to evaluate the separated and combined influences of compliance and resistance on the delivered VT accuracy...

BACKGROUND: The global threat of Carbapenem-resistant Acinetobacter baumannii (CRAB) has intensified as resistance to carbapenems continues to rise in recent decades. We aimed to explore risk factors, molecular epidemiology, and antimicrobial therapy of CRAB infection. METHODS: The clinical data of 110 patients infected with A. baumannii from December 2021 to December 2022 were retrospectively analyzed. Patients were divided into a carbapenem-resistance group (55 patients) and carbapenem-sensitive group (CSAB; 55 patients) based on resistance to carbapenem, and the risk factors of patients infected with CRAB were analyzed...
