Acute respiratory distress syndrome (ARDS) is the most severe form of acute respiratory failure characterized by diffuse alveolar and endothelial damage. The severe pathophysiological changes in lung parenchyma and pulmonary circulation together with the effects of positive pressure ventilation profoundly affect heart lung interactions in ARDS. The term pulmonary vascular dysfunction (PVD) refers to the specific involvement of the vascular compartment in ARDS and is expressed clinically by an increase in pulmonary arterial (PA) pressure and pulmonary vascular resistance both affecting right ventricular (RV) afterload. ⋯ The use of selective pulmonary vasodilators and lung protective mechanical ventilation strategies are therapeutic interventions that can ameliorate PVD. Prone positioning and the open lung approach (OLA) are especially attractive strategies to improve PVD due to their effects on increasing functional lung volume. In this review we will describe some pathophysiological aspects of heart-lung interactions during the ventilatory support of ARDS, its clinical assessment and discuss therapeutic interventions to prevent the occurrence and progression of PVD and RV failure.

Patients with a left ventricular assist device (LVAD) are at a higher risk of ischemic stroke (IS) and intracranial hemorrhage (ICH). There is limited data available on risk factors and outcomes associated with IS and ICH in LVAD patients. ⋯ Increasing comorbidity burden significantly increases the risk of both IS and ICH with LVAD. In our cohort, the incidence of IS and ICH increases the mortality 4- and 18-fold, respectively. Renal disease, liver disease and abnormal coagulation profile were independent predictors of mortality in LVAD patients with IS.

Multiple approaches to the hip joint have been developed utilizing various intervals and/or intermuscular planes when performing a total hip arthroplasty (THA), each proposing certain advantages. Of these, the Röttinger approach (modified anterolateral or Watson-Jones) is potentially muscle-sparing. Multiple studies have demonstrated favorable outcomes with this approach. However, others showed more complications with a slow learning curve. Due to the paucity of evidence we conducted this study to: (I) present our operative experience and technique of the Röttinger approach; (II) compare short-term complications and operative room (OR) times of this approach to the direct lateral; and (III) review the available literature. ⋯ In this analysis of a single-surgeon experience of the Röttinger approach compared to the direct lateral, we presented our experience with the technique and demonstrated the safety and feasibility of this relatively novel approach. Our study results demonstrated that patients who underwent this approach had similar short-term complications and OR times to those who underwent the direct lateral approach. Additionally, our findings agree with previous comparative studies that demonstrated similar outcomes of this approach. Therefore, it can be used as an alternative for primary THA.

In the context of healthcare delivery, the vulnerabilities of patients in the intensive care unit (ICU) are intricately linked with those experienced on a daily basis by caregivers in the ICU in a symbiotic relation, whereby patients who are suffering can in turn engender suffering in the caregivers. In the same way, caregivers who are suffering themselves may be a source of suffering for their patients. The vulnerabilities of both patients and caregivers in the ICU are simultaneously constituted through a process that is influenced on the one hand by the healthcare objectives of the ICU, and on the other hand, by the conformity of the patients who are managed in that ICU. ⋯ Constructing the patient, collectively redefining the patient's identity, and ascribing the patient to a specific healthcare trajectory enables professionals to circumscribe, contain and fight against the spectrum of extreme vulnerabilities of their patients. Imposing this normative framework is the sole means of guiding these professionals through their daily practices. In spite of this, situations of suffering remain a constitutive feature of the caregiving relation in the ICU.

Sepsis and acute respiratory distress syndrome (ARDS) are life threating diseases with high mortality and morbidity in all the critical care units around the world. After decades of research, and numerous pre-clinical and clinical trials, sepsis and ARDS remain without a specific and effective pharmacotherapy and essentially the management remains supportive. In the last years cell therapies gained potential as a therapeutic treatment for ARDS and sepsis. ⋯ Also, the heterogeneity of patients with sepsis and ARDS is massive, and establish a target population or the stratification of the patients will help us to determine better the therapeutic effect of these cell therapies. In this review we are going to describe briefly the different cell types, their potential sources and characteristics and mechanism of action. Here, also we elucidate the results of several pre-clicinical and clinical studies in ARDS and in sepsis and the future directions of these studies.
