The role of waddling gait in balance control during pregnancy.

Background: Pregnant people experience many physical changes which might affect their walking pattern. Waddling gait is a common gait pattern pregnant individuals adopt. It is unknown whether waddling gait is a sign of poor balance or a protective mechanism against loss of balance, so the aim of this study was to understand why some pregnant individuals adopt this gait pattern.

Enhancing fall risk assessment: instrumenting vision with deep learning during walks.

Background: Falls are common in a range of clinical cohorts, where routine risk assessment often comprises subjective visual observation only. Typically, observational assessment involves evaluation of an individual's gait during scripted walking protocols within a lab to identify deficits that potentially increase fall risk, but subtle deficits may not be (readily) observable. Therefore, objective approaches (e.

Different neurocognitive controls modulate obstacle avoidance through pregnancy.

Understanding why falls during pregnancy occur at over 25% rate over gestation has clinical impacts on the health of pregnant individuals. Attention, proprioception, and perception of the environment are required to prevent trips and falls. This research aimed to understand how the changes to these neurocognitive processes control obstacle avoidance through gestation.

Determining fall risk change throughout pregnancy: the accuracy of postpartum survey and relationship to fall efficacy.

All epidemiological studies on pregnancy fall risk to date have relied on postpartum recall. This study investigated the accuracy of postpartum recall of falls that were reported during pregnancy, including assessment of fall efficacy as a possible reason for recall inaccuracy. Twenty participants reported fall experiences weekly during pregnancy, but one participant was excluded as an outlier.

Exploring pandemic preparedness in higher education: lessons learnt from students' lived experiences during a critical time.

Background: The COVID-19 pandemic has had a marked impact on educational disruption and progression of students. Linked to this, studies have demonstrated increases in depression, anxiety, and stress, with long-term outcomes yet to be understood. Students in Higher Education (HE) were at particular risk due to circumstances such as financial stress from job loss, shifting to online learning and uncertainties about the future, with many international students isolated from social support networks.

Upper extremity kinematics during walking gait changes through pregnancy.

Background: Thirty percent of adults in the United States use wearable fitness devices as of 2020 [1], such as fitness watches, to monitor and track health and physical activity parameters. Physical changes during pregnancy may impact wrist worn device accuracy. The arms may be needed as compensation during walking because thorax axial rotation may be inhibited by pelvic tilt during pregnancy [2].

Three-dimensional imaging mass cytometry for highly multiplexed molecular and cellular mapping of tissues and the tumor microenvironment.

A holistic understanding of tissue and organ structure and function requires the detection of molecular constituents in their original three-dimensional (3D) context. Imaging mass cytometry (IMC) enables simultaneous detection of up to 40 antigens and transcripts using metal-tagged antibodies but has so far been restricted to two-dimensional imaging. Here we report the development of 3D IMC for multiplexed 3D tissue analysis at single-cell resolution and demonstrate the utility of the technology by analysis of human breast cancer samples.

Self-selection of gestational lumbopelvic posture and bipedal evolution.

Background: Not all pregnant women seem to select the more curved lumbopelvic posture that their sexual dimorphic anatomy allows even though many previous researchers have assumed lumbopelvic curvature to be standard during pregnancy. This study is vital to understanding coevolution of lumbopelvic sexual dimorphism and bipedalism, and understanding some clinical implications of intervening in gestational posture changes.

Research Questions: Are there anthropometric changes that correspond with selection of lumbopelvic curvature change during pregnancy? What are the biomechanical costs and benefits of gestational lumbopelvic curvature change?

Methods: Twenty pregnant women were tested at five different times in the 2nd and 3rd trimesters of pregnancy.

Shoulder and elbow requirements during sagittal reach as a result of changing anthropometry throughout pregnancy.

During pregnancy, anthropometric and physiological changes can result in difficulty reaching for and lifting everyday objects. The aims of this study were to determine the changes in sagittal plane anterior reach space (SPARS) and shoulder/elbow strength requirements throughout pregnancy. Seventeen participants were tested through a longitudinal observational cohort study between 16 and 36 weeks gestation in four-week intervals.

Correlations between joint kinematics and dynamic balance control during gait in pregnancy.

Background: Dynamic balance control degrades during pregnancy, but it is not yet understood why. Mechanical aspects of the body should directly affect walking balance control, but we have recently published papers indicating that weight gains during pregnancy explain very little dynamic balance changes. Our goal was to determine if lower extremity joint kinematic changes are an indicator of walking balance control.

2020 update of the WSES guidelines for the management of acute colonic diverticulitis in the emergency setting.

Acute colonic diverticulitis is one of the most common clinical conditions encountered by surgeons in the acute setting. An international multidisciplinary panel of experts from the World Society of Emergency Surgery (WSES) updated its guidelines for management of acute left-sided colonic diverticulitis (ALCD) according to the most recent available literature. The update includes recent changes introduced in the management of ALCD.

COVID-19 the showdown for mass casualty preparedness and management: the Cassandra Syndrome.

Since December 2019, the world is potentially facing one of the most difficult infectious situations of the last decades. COVID-19 epidemic warrants consideration as a mass casualty incident (MCI) of the highest nature. An optimal MCI/disaster management should consider all four phases of the so-called disaster cycle: mitigation, planning, response, and recovery.

An analysis of postpartum walking balance and the correlations to anthropometry.

Background: Falls caused by balance issues during pregnancy are quite common, and these issues can continue postpartum, potentially posing a danger to both the mother and baby. While there has been research on changes to walking gait during pregnancy, walking balance in the postpartum period has yet to be examined. Therefore, the aims of this study were to examine if balance changes persist in postpartum and the contribution of anthropometry changes.

Multi-Organ Gland Segmentation Using Deep Learning.

Clinical morphological analysis of histopathology samples is an effective method in cancer diagnosis. Computational pathology methods can be employed to automate this analysis, providing improved objectivity and scalability. More specifically, computational techniques can be used in segmenting glands, which is an essential factor in cancer diagnosis.

Concussed athletes walk slower than non-concussed athletes during cognitive-motor dual-task assessments but not during single-task assessments 2 months after sports concussion: a systematic review and meta-analysis using individual participant data.

Objectives: To determine whether individuals who sustained a sports concussion would exhibit persistent impairments in gait and quiet standing compared to non-injured controls during a dual-task assessment .

Design: Systematic review and meta-analysis using individual participant data (IPD).

Data Sources: The search strategy was applied across seven electronic bibliographic and grey literature databases: MEDLINE, EMBASE, CINAHL, SportDISCUS, PsycINFO, PsycARTICLES and Web of Science, from database inception until June 2017.

Stand-to-sit kinematic changes during pregnancy correspond with reduced sagittal plane hip motion.

Background: The stand-to-sit motion has been linked to falls during pregnancy. It is also used in the clinical evaluation of functional performance. The physical and physiological changes during pregnancy may necessitate a change in stand-to-sit kinematic performance.

Anthropometry, standing posture, and body center of mass changes up to 28 weeks postpartum in Caucasians in the United States.

Background: Anthropometric models are used when body center of mass motion is calculated for assessment of dynamic balance. It is currently unknown how body segments and posture change in the postpartum period. Therefore, this study was conducted to evaluate the longitudinal changes in anthropometry, center of mass, and standing posture postpartum.

Anthropometric Changes During Pregnancy Provide Little Explanation of Dynamic Balance Changes.

The authors investigated the relationship between anthropometric changes and dynamic balance changes during pregnancy. A total of 15 participants were recruited for testing, using a convenience sample, from 12 weeks of gestation until childbirth. The authors measured body anthropometry with a tape measure and calipers.

Guided Hands-On Activities Can Improve Student Learning in a Lecture-Based Qualitative Biomechanics Course.

A qualitative biomechanics (functional anatomy) course is a typical course in kinesiology curriculum. Most evidence suggests that biomechanics learning could be improved with the inclusion of laboratory experiences. However, implementing laboratories into biomechanics curriculum is difficult due to cost and time constraints.

Walking balance on a treadmill changes during pregnancy.

Background: Altered standing balance during pregnancy has been previously reported. To date, body center of mass (bCOM) motion has not been used to track balance changes in this population. We recently compared three methods to determine the torso center of mass (tCOM) location (via force plate acquired center of pressure calculation, using Pavol surface anthropometry measurements, and a combination of the two) to use in calculating the bCOM during pregnancy.

A comparison of methods to determine center of mass during pregnancy.

Balance changes during pregnancy likely occur because of mass gains and mass distribution changes. However, to date there is no way of tracking balance through center of mass motion because no method is available to identify of the body center of mass throughout pregnancy. We compared methods for determining segment masses and torso center of mass location.

Ruthenium counterstaining for imaging mass cytometry.

Imaging mass cytometry is a novel imaging modality that enables simultaneous antibody-based detection of >40 epitopes and molecules in tissue sections at subcellular resolution by the use of isotopically pure metal tags. Essential for any imaging approach in which antigen detection is performed is counterstaining, which reveals the overall structure of the tissue. Counterstaining is necessary because antigens of interest are often present in only a small subset of cells, and the rest of the tissue structures are not visible.

Cholecystectomy in Emilia-Romagna region (Italy): A retrospective cohort study based on a large administrative database.
