REVIEW

Obstetric hemorrhage is one of the leading, as well as one of the most treatable, causes of maternal morbidity and mortality worldwide. As obstetric hemorrhage often occurs in patients without risk factors, there is virtually unanimous agreement from obstetric professional societies to establish obstetric hemorrhage protocols in anticipation of these emergencies. These protocols involve multidisciplinary teams in which the transfusion service plays an essential and vital role. This manuscript will examine the epidemiology of obstetric hemorrhage, risk factors that may be present, and recommendations for these protocols, with a focus on massive transfusion protocols, laboratory testing, cell salvage and use of pharmacologic adjuvant therapy including tranexamic acid and factor concentrates...

REVIEW
Cláudia C Miranda, Tiago G Fernandes, Maria Margarida Diogo, Joaquim M S Cabral
A low percentage of novel drug candidates succeed and reach the end of the drug discovery pipeline, mainly due to poor initial screening and assessment of the effects of the drug and its metabolites over various tissues in the human body. For that, emerging technologies involving the production of organoids from human pluripotent stem cells (hPSCs) and the use of organ-on-a-chip devices are showing great promise for developing a more reliable, rapid and cost-effective drug discovery process when compared with the current use of animal models...

Post-marketing surveillance is useful to collect safety data in real-world clinical settings. In this study, we firstly applied the post-marketing real-world data on a mechanistic model analysis for neutropenic profiles of eribulin in patients with recurrent or metastatic breast cancer (RBC/MBC). Demographic and safety data were collected using an active surveillance method from eribulin-treated RBC/MBC patients. Changes in neutrophil counts over time were analyzed using a mechanistic pharmacodynamic model...

Unilateral pulmonary vein atresia is a rare entity, usually congenital in origin. It is thought to result from failure of incorporation of common pulmonary vein to left atrium. Patients often present with recurrent chest infections and haemoptysis during infancy or early childhood. Associated anomalies are commonly present in these cases. Pulmonary angiography is generally used for definitive diagnosis; however, characteristic imaging findings on latest multislice CT can be virtually diagnostic.

BACKGROUND: Management of adult congenital heart disease (ACHD) patients requires understanding of its complex morphology and functional features. An innovative imaging technique has been developed to display a virtual multi-planar reconstruction obtained from contrast-enhanced multidetector-computed tomography (MDCT) corresponding to the same cross-sectional image from transthoracic echocardiography (TTE). The aim of this study is to assess the usefulness of this imaging technology in ACHD patients...

Dental imaging has seen a rapid technological advance over the last several years. Not only has most x-ray based diagnostic technology been digitized, with the possibility of low dose 3D computed tomography imaging, but many novel optical imaging techniques have now also been adopted in a more therapeutic imaging of the dental patient. When combining and manipulating such different digital image data, clinicians can now easily plan and simulate treatments on-screen, use 3D printed models and aids to assist in accurate transfer of the virtual planning or even follow-up their treatments over time...

Although emotional reactivity to social rejection has been examined in patients with borderline personality disorder (BPD) in several studies, the effects of other aspects of social feedback, such as evaluation of one's opinions that concern self-esteem, have not been addressed yet. The objective of this study was to examine emotional responses of BPD patients after exchanging personal opinions in a new, ecologically valid virtual peer interaction paradigm ("chatroom paradigm"). In this paradigm, 21 BPD patients and 21 healthy controls received peer feedback on their own statements and rated the intensity of their own emotional responses (happiness, sadness, anger, and shame) and the self or other affirmation in response to agreement, disagreement, and neutral statements...

BACKGROUND: Reviews of weight loss mobile apps have revealed they include very few evidence-based features, relying mostly on self-monitoring. Unfortunately, adherence to self-monitoring is often low, especially among patients with motivational challenges. One behavioral strategy that is leveraged in virtually every visit of behavioral weight loss interventions and is specifically used to deal with adherence and motivational issues is problem solving. Problem solving has been successfully implemented in depression mobile apps, but not yet in weight loss apps...

Hemophilia B (HB) is an X-linked bleeding disorder caused by deficiency of factor IX (FIX). Patients with the severe form (FIX <1%) account approximately for 30 to 45% of persons with HB and usually suffer from recurrent joint, soft-tissue, and muscle bleeds. The availability of safe plasma-derived and recombinant products has virtually abolished the risk of viral infections and the adoption of prophylactic regimens has attenuated the impact of hemophilic arthropathy. Therefore, the development of an inhibitor against FIX is currently the most serious complication that can still occur in the new generations of HB patients...

Acquired brain injury patients often report navigation impairments. A cognitive rehabilitation therapy has been designed in the form of a serious game. The aim of the serious game is to aid patients in the development of compensatory navigation strategies by providing exercises in 3D virtual environments on their home computers. The objective of this study was to assess the usability of three critical gaming attributes: movement control in 3D virtual environments, instruction modality and feedback timing. Thirty acquired brain injury patients performed three tasks in which objective measures of usability were obtained...
