Although COVID-19 in pregnant women and their neonates has been demonstrated, there is not enough evidence about how this vertical transmission occurs. This report describes a SARS-CoV-2 infection in a 21-year-old mother-daughter duo at the time of birth, focusing on the viral RNA detection in the stool of both and the human breast milk.Research, collaboration, and knowledge exchange are critical to global efforts to tackle antimicrobial resistance (AMR). Different healthcare economies are faced with different challenges in implementing effective strategies to address AMR. Building effective capacity for research to inform AMR-related strategies and policies is recognised as an important contributor to success. Interdisciplinary, intersector, as well as international collaborations are needed to span global to local efforts to tackle AMR. The development of reciprocal, long-term partnerships between collaborators in high-income and in low- and middle-income countries (LMICs) needs to be built on principles of capacity building. Using case studies spanning local and international research collaborations to codesign, implement, and evaluate strategies to tackle AMR, we have evaluated and build upon the ESSENCE criteria for capacity building in LMICs. The first case study describes the local codesign and implementation of antimicrobial stewardship (AMS) in the state of Kerala in India. The second case study describes an international research collaboration investigating AMR surgical patient pathways in India, the UK, and South Africa. We describe the steps undertaken to develop robust, agile, and flexible AMS research and implementation teams. Notably, investing in capacity building ensured that the programmes described in these case studies were sustained through the current severe acute respiratory syndrome coronavirus pandemic. Describing the strategies adopted by a local and an international collaboration to tackle AMR, we provide a model for capacity building in LMICs that can support sustainable and agile AMS programmes.
  To examine the attitudes of adolescent and young adults (AYA) toward long-acting reversible contraception (LARC), and to assess how attitudes are associated with acceptability.
 
  Survey.
 
  Children's Hospital Colorado Adolescent Family Planning Clinic in Aurora, Colorado.
 
  Young persons 14-24years of age presenting for any type of visit between March and August2018.
 
  A total of 332 participants were enrolled; the majority (62.3%) had high LARC acceptability. We found 5 "attitude" factors 77.7% of the sample endorsed "Effective" attitudes (eg, wants most effective method), 37.3% endorsed "Good attributes" (eg, discreet, convenient), 23.1% endorsed "Scary" (eg, fears device will move), 16.1% endorsed "Bad for health," (eg, too many side effects), and 9% endorsed "Not for me" (eg, concerns about pain). Although participants who endorsed "Effective" (OR 6.60, 95% CI 3.01-14.49) and "Good attributes" (OR 3.17, 95% CI 1.51-6.66) were more likely to have high LARC acceptability than those who endorsed "Scary" (OR 0.28, 95% CI (0.13-0.61)) and "Not for me" (OR 0.07, 95% CI 0.01-0.41) factors, approximately 10% of participants with high LARC acceptability endorsed "Scary" or "Bad for health" attitudes, whereas 54% of those with low LARC acceptability endorsed "Effective" attitudes.
 
  Although most participants had high LARC acceptability and valued contraceptive effectiveness, the association between LARC attitudes and acceptability is nuanced. Providers should identify and discuss young people's contraceptive knowledge, attitudes, and acceptability.

However, loading-unrelated aspects of trabecular architecture remain unclear. We used synchrotron radiation-based X-ray microtomography to study the 3D microarchitecture of newly formed trabecular tissue in a defect produced in the cortical region of the rat tibia diaphysis, in the absence (7, 14, and 21 days) or the presence (21 days) of carbonated hydroxyapatite/alginate (cHA) microspheres. This work provides the first evidence that the woven bone trabecular network, formed during the healing process, displays a well-organized 3D microarchitecture consisting of nodes with 3 (3-N), 4 (4-N) and 5 (5-N) connecting trabeculae, with a mean relative abundance of (3-N)/(4-N)/(5-N) = 66/24/7, for the analyzed periods. The measured inter-trabecular angles (ITA) distribution presented a Gaussian profile, with mean value at 115° for 3-N nodes, and 105° for 4-N nodes, close to the angles of idealized 3D regular struc is spatially organized according to the principle of tensegrity. This microarchitecture is comprised of highly symmetric geometric motifs and is an intrinsic characteristic of trabecular growth, regardless of hierarchical scale or mechanical stimulation. The addition of a biodegradable nanostructured calcium phosphate graft did not disrupt trabecular microarchitecture; however, graft biodegradation should be controlled to optimize the reproduction of intrinsic trabecular motifs throughout the defect.Collecting information about molecular organisation on biological materials such as bone and dentin represents a major challenge in attaining a better understanding of their mechanical properties. To that end, solid state Nuclear Magnetic Resonance (ssNMR) spectroscopic study is an appropriate strategy to provide atomic structural details on these amorphous composite materials.  https://www.selleckchem.com/products/atogepant.html  However, species like water molecules and hydroxyl groups are usually observed through 1H magic angle spinning (MAS) ssNMR that suffers from poor resolution due to strong signal overlapping, making their identification difficult. This paper proposes a set of ssNMR experiments for 1H characterization of the main components of human dentin, based on homo- and hetero-nuclear dipolar couplings and composed mostly of fast 1D experiments. The 1H assignment is assisted by straightforward sample modifications vacuum drying, deuterium exchange and demineralization. These experiments allow the hydrogen signal edition of dentin species like water molecules, HPO42- and OH- groups, depending on their localization (bound to the organic phase, linked to apatite or at the interface) and their dynamic behaviour.
