Chitosan-covered tamponade for the treatment of postpartum hemorrhage: a registry-based cohort study assessing outcomes and risk factors for treatment failure.

Background: Postpartum hemorrhage (PPH) is one of the leading causes of maternal morbidity and mortality worldwide. Intrauterine hemostatic devices are recommended when PPH does not respond to medical treatment. The objective of this study was to assess the factors leading to unsuccessful intrauterine therapy with a chitosan-covered tamponade (CT) for the treatment of PPH and to evaluate clinical outcomes based on real-world data.

Short and long-term menstrual, reproductive, and mental health outcomes after the intrauterine use of chitosan tamponade or the Bakri balloon for severe postpartum hemorrhage: an observational study.

Objective: This retrospective follow-up study analyzes the effect of intrauterine postpartum hemorrhage (PPH) therapy on menstrual, reproductive, and mental health outcomes.

Methods: All women who delivered at a university hospital between 2016 and 2021 with PPH and who needed intrauterine therapy were included. A questionnaire on well-being, menses, fertility, and reproductive outcomes was mailed to the patients.

Does the use of chitosan covered gauze for postpartum hemorrhage reduce the need for surgical therapy including hysterectomy? A databased historical cohort study.

Objectives: Postpartum hemorrhage (PPH) is still one of the leading causes of maternal mortality worldwide. Recently effective PPH therapy with uterine packing with the chitosan-covered gauze was shown. This databased retrospective case-control study compares the therapy success of the chitosan tamponade with that of the balloon tamponade and medical therapy only.

Conservative management of abnormally invasive placenta complicated by local hyperfibrinolysis and beginning disseminated intravascular coagulation.

Introduction: Abnormally invasive placenta (AIP) is often associated with high maternal morbidity. In surgical treatment, caesarean hysterectomy or partial uterine resection may lead to high perioperative maternal blood loss. A conservative treatment by leaving the placenta in utero after caesarean delivery of the baby is an option to preserve fertility and to reduce peripartum hysterectomy-related morbidity.

Development and Validation of a Shortened Language-Specific Version of the UNRAVEL Placekeeping Ability Performance Measuring Tool.

The current study aimed to develop a shortened language-specific (Polish) version of the UNRAVEL task  (Altmann, Trafton, & Hambrick, 2014) and to verify whether the adaptation yields valid and reliable data about placekeeping ability. Since the original procedure is intended to investigate task performance referring to placekeeping operations under conditions of task interruptions, we used this tool in the context of a multitasking situation. The adopted version differs from the original in that we reduced the number of steps in the procedure and changed the rules set, using an acronym WINDA (a word meaning elevator in Polish).

Validity of increasing the number of motor control tests within a test battery for discrimination of low back pain conditions in people attending a physiotherapy clinic: a case-control study.

Objectives: To develop a time-efficient motor control (MC) test battery while maximising diagnostic accuracy of both a two-level and three-level classification system for patients with non-specific low back pain (LBP).

Design: Case-control study.

Setting: Four private physiotherapy practices in northern Germany.

Proxy Users Enable Older People Creative Writing on the Web.

This paper presents several state-of-the-art concepts within Internet studies and applies them to the creative writing of older people using the Internet. For more than 10 years two creative Web users aged 80+, assisted by younger proxy users, were involved in preliminary action research. It was aimed at finding patterns of inducing older people's creativity and sharing their wisdom with the general Internet audience.

Eye tracking cognitive load using pupil diameter and microsaccades with fixed gaze.

Pupil diameter and microsaccades are captured by an eye tracker and compared for their suitability as indicators of cognitive load (as beset by task difficulty). Specifically, two metrics are tested in response to task difficulty: (1) the change in pupil diameter with respect to inter- or intra-trial baseline, and (2) the rate and magnitude of microsaccades. Participants performed easy and difficult mental arithmetic tasks while fixating a central target.

An Inverse-Linear Logistic Model of The Main Sequence.

A model of the main sequence is proposed based on the logistic function. The model's fit to the peak velocity-amplitude relation resembles an S curve, simultaneously allowing control of the curve's asymptotes at very small and very large amplitudes, as well as its slope over the mid-amplitude range. The proposed inverse-linear logistic model is also able to express the linear relation of duration and amplitude.

EMG activity in response to static and dynamic facial expressions.

The EMG activity associated with static and dynamic facial expressions (morphs with happy or angry emotions) were compared. We hypothesized that dynamic faces would (a) enhance facial muscular reactions and (b) evoke higher intensity ratings. Our analysis showed that dynamic expressions were rated as more intense than static ones.

Sex differences in perception of emotion intensity in dynamic and static facial expressions.

Most research on the perception of emotional expressions is conducted using static faces as stimuli. However, facial displays of emotion are a highly dynamic phenomenon and a static photograph is its very unnatural representation. The goal of the present research was to assess the role of stimuli dynamics as well as subjects' sex in the perception of emotional expressions.

Herbarulide, a ketodivinyllactone steroid with an unprecedented homo-6-oxaergostane skeleton from the endophytic fungus pleospora herbarum1.

The novel ketodivinyllactonic steroid, herbarulide (1), deviating from the brassinosteroids in the position of the oxygen, was isolated from the endophytic fungus Pleospora herbarum. The structure was determined by extensive NMR studies, including particularly HMQC and HMBC experiments.
