This study described foot bone motion using a biomechanically near-physiological gait simulator with 6 DOF of the tibia. The kinematic data helps to clarify previous descriptions of several joint kinematics that are difficult to study in vivo. The methodology also provides a platform for researchers to explore more invasive foot biomechanics under dynamic and near-physiologic conditions.

Heat shock transcription factor1 (HSF1) was overexpressed to promote glutaminolysis and activate mTOR in colorectal cancer (CRC). Here, we investigated the mechanism for cancer-specific overexpression of HSF1.
HSF1 expression was analyzed by chromatin immunoprecipitation, qRT-PCR, immunohistochemistry staining and immunoblotting. HSF1 translation was explored by polysome profiling and nascent protein analysis. Biotin pulldown and m6A RNA immunoprecipitation were applied to investigate RNA/RNA interaction and m6A modification. The relevance of HSF1 to CRC was analyzed in APC
and APC

mice.
HSF1 expression and activity were reduced after the inhibition of WNT/β-catenin signaling by pyrvinium or β-catenin knockdown, but elevated upon its activation by lithium chloride (LiCl) or β-catenin overexpression. There are much less upregulated genes in HSF1-KO MEF treated with LiCl when compared with LiCl-treated WT MEF. HSF1 protein expression was positively correlated with β-catenin expression in cell lition of β-catenin-driven cancers.
Hypertension is a disease with significant clinical and socio-economic consequences. The reduction in cardiovascular mortality and morbidity in patients treated for hypertension is directly related to the magnitude of blood pressure reduction. Diuretics have proven useful for the prevention of cardiovascular complications in addition to a long history of safety and efficacy. The main aim for this meta-analysis is to compare the efficacy of the combination of angiotensin receptor blocker (ARB) and chlorthalidone (CTLD) to the combination of ARB and hydrochlorothiazide (HCTZ) in patients with hypertension.
A comprehensive literature search was conducted through electronic databases PubMed, MEDLINE, Scopus, PsyInfo, Cochrane, eLIBRARY.ru, http//ClinicalTrials.gov and http//www.clinicaltrialsregister.eu in July 2020 to identify studies that investigate the effect of the combination of angiotensin receptor blocker with chlorthalidone or hydrochlorothiazide on the systolic and diastolic blood pressure in patiensuggests a small but significant favor for CTLD in blood pressure control when compared to HCTZ. We believe it should be considered as a valuable alternative for HCTZ and an option for fixed dose combinations with an ARB although further research is required.
Intercellular exchange between the oocyte and its surrounding cells within the follicular environment is critical for oocyte maturation and subsequent development. In vertebrates this exchange is facilitated through gap junctions formed by connexin membrane proteins. Another family of membrane proteins called pannexins are able to form single membrane channels that allow cellular exchanges with the extracellular environment. The most ubiquitously expressed and studied member, pannexin 1 (PANX1), has yet to be described thoroughly in female reproductive tissues or functionally studied during oocyte maturation. Here, we look into the expression of pannexin 1 in bovine cumulus-oocyte complexes (COCs), as well as, its potential role in oocyte maturation and development.
We show that pannexin 1 is expressed in bovine COCs and that the expression of PANX1 was significantly lower in COCs isolated from large antral follicles (> 5 mm) compared to those isolated from small antral follicles (< 2 mm). Supporting this we also found lower expression of PANX1 in oocytes with higher developmental potential when compared to oocytes with lower developmental potential. We further found that PANX1 channel inhibition during in vitro maturation resulted in temporarily delayed meiotic maturation and improved in vitro developmental outcomes while decreasing intercellular reactive oxygen species.
These data suggests PANX1 is differentially expressed at a critical stage of follicular development when oocytes are acquiring developmental competence, and may play a role in the timing of oocyte maturation.

Several cardiovascular pathologies cause heart failure. Heart failure with reduced ejection fraction (HFrEF) is deteriorated by neurohormonal activation, so neurohormonal antagonists are recommended in HFrEF patients. They improve morbidity, mortality, and quality of life and reduce hospital admissions. Heart failure treatment guidelines recommend achieving target doses of those drugs. However, many clinicians prescribe suboptimal doses for the fear of inducing hypotension. The aim of this systematic review and meta-analysis is to understand whether it is still beneficial to uptitrate the doses of those drugs even if the patient is at the risk of developing hypotension.
The primary outcome is symptomatic or asymptomatic hypotension in patients on neurohormonal antagonist drugs for HFrEF. Secondary outcomes are blood pressure reduction, New Yok Heart Association functional class deterioration, non-fatal cardiovascular events, cardiovascular mortality, all-cause mortality, heart failure hospitalizations, an

The Maternal and Child Health (MCH) handbook is an integrated home-based record (HBR) designed to record in a single document all the information regarding health services provided to a pregnant woman and her child. The MCH handbook has the potential to support continuity of care which is key to strengthening maternal, newborn and child health. However, there is a lack of an integrated system to manage the health of pregnant women and young children on an ongoing basis in Angola. Thus, the Angolan Ministry of Health is partnering with the Japan International Cooperation Agency to build the capacity of healthcare providers through trainings and implementation of the MCH handbook to improve service utilisation. In this study, we will estimate the impact of an intervention package including distribution of MCH handbook and its supplementary interventions to women, on the utilisation of services provided at healthcare facilities from pregnancy through the postnatal and early childhood period.
This study is a r revising the current trial version of the Angola MCH handbook and provide a framework for policy guiding nationwide scale-up and distribution of the MCH handbook.

Mobility, one of the basic daily activities, helps in carrying out routine work, which contributes to people's well-being. A lack of friendly and accessible infrastructure may act as a barrier, which limits older adults' contributions and participation in society. Hence, it is important to have an enabling environment for older adults to carry out their activities independently at ease. There is ample research evidence about effective interventions on urban mobility infrastructures, but there is a lack of evidence regarding what works, for whom, and in what circumstances. Hence, there is a need to identify the contextual factors for different regions to design region-specific interventions. The aim of this realist synthesis is to develop an evidence-informed framework for safe and accessible urban mobility infrastructures for older adults in low- and middle-income countries.
A realist review will be undertaken using the following process (1) development of a program theory, (2) search strategy and informa. The results of this study will support evidence-based decision-making on urban mobility systems and will be of interest to various stakeholders. Dissemination will be done through conference presentations, policy briefs, media, and peer-reviewed journals. Implications for future research will be discussed.

Novel coronavirus disease 2019 presents with fever, dry cough, fatigue, and shortness of breath in most cases; however, some rare manifestations in other organs have also been reported so far.
Here, the case of a 69-year-oldIranian man with coronavirus disease 2019 is presented who suffered from frequent episodes of vasopressor-resistant hypotension during intensive care unit admission, which was finally attributed to the occurrence of acute adrenal insufficiency.
As this is a rare complication, adrenal insufficiency might be easily overlooked. However, early detection of this disease among critically ill patients infected with coronavirus disease 2019 could be lifesaving, especially among those unresponsive to vasopressor agents.

Osteoarthritis (OA) is a health condition sensitive to patient's preferences and values regarding the benefits and risks of the different treatment options. In this sense, patient decision aids (PtDA) can play an important role in helping patients to incorporate their values, needs, and preferences into the decision-making process, thus improving person-centered care. Previous research has focused almost exclusively on knee OA, and therefore, the aim of this study is to develop and evaluate the effectiveness of a PtDA for patients with hip OA.
The general design consists of two phases (1) design a web-based PtDA for patients with hip OA, following the recommended procedures systematic review of safety/effectiveness of treatments, and an iterative process of development with the help of an Advisory Committee composed of health professionals and patients, and (2) to evaluate the impact of the PtDA on hip OA patients' decision-making process related with their treatment. For that aim, a multicenter randomized controlled trial will be carried out with 124 patients with hip OA in Tenerife (Spain) comparing intervention or usual care.
PtDAs have been recommended as a useful and effective resource for improving PCC in many health conditions. The intervention is intended to empower patients by fostering their active participation during the decision-making process about their treatment and by ensuring they make informed decisions congruent with their values and preferences. This study will contribute to the scientific knowledge about effectiveness of PtDAs in hip OA, in order to improve the quality of health care offered to these patients.
