Linkages among forest, water, and wildlife: a case study from Kalapani community forest in Lamahi bottleneck area in Terai Arc Landscape.

Forest and water are important entities for sustaining life on earth. In a terrestrial ecosystem, linkages between the entities creates a mosaic benefiting the wildlife by creating the suitable habitat. In turn, communities get benefits stemming up from ecosystem services such as fodder, fuelwood, and water. We present a case study from a forest restoration project to assess the linkages between forest, water and wildlife across Lamahi bottleneck area in Terai Arc Landscape. We used combination of surveys such as forest area and canopy cover change (2001-2016) analysis followed by household questionnaire, water hole, camera trapping including process documentation. Forest area has increased by ~20 km2 in last 16 yrs. followed by number of water spouts along the identified tributaries. Water spouts are conserved in the form of conservation pond by the communities living downstream and utilized in the vegetable farming. Communities have benefited financially (~ US$ 1,252) contributing to their income level from the sale of fresh season vegetables in nearby market. Camera trap survey including the assessment of historical records showed presence of wildlife including elephant, hyena and other small carnivores in and around bottleneck forest. Both, motivation and enthusiastic support from local communities followed by the conducive government policies led to improve condition of natural resources over the period. This has also created a mosaic habitat for wildlife forming functional connectivity along the linear Terai Arc Landscape

Promoting gender equality across the sustainable development goals

Gender issues, and gender equality in particular, can be regarded as cross-cutting issues in the implementation of the Sustainable Development Goals (SDGs), even though it is unclear how they are taken into account. This study addresses this information gap by performing an assessment of the emphasis on gender issues across all the other 16 SDGs, in addition to SDG5, through a literature review and case study analysis, the basis for the newly developed framework, highlighting specific actions associated to each SDG. The 13 countries addressed in the 16 case studies include China, India, or Australia and illustrate the inclusion of SDG5 into the SDGs. Using an SDG matrix, the SDG targets are analysed. Those where an emphasis on gender equality is important in allowing them to be achieved are listed. The novelty of our approach resides in offering an in-depth analysis of how gender issues interact with the other SDGs, proposing a new analysis framework clearly identifying SDGs 1, 4, 11, 12, 14 and 16 demanding further attention for successful SD gender implementation and illustrating specific areas where further actions may be necessary, which may be used by policy-makers, raising further awareness on gender equality contribution to achieve the SDGs. A set of recommendations aimed at placing gender matters more centrally in the SDGs delivery are presented as a final contribution. These focus on the need for greater awareness and attention to good practices, to achieve successful implementation initiatives.peer-reviewe

Epicardial cells derived from human embryonic stem cells augment cardiomyocyte-driven heart regeneration.

The epicardium and its derivatives provide trophic and structural support for the developing and adult heart. Here we tested the ability of human embryonic stem cell (hESC)-derived epicardium to augment the structure and function of engineered heart tissue in vitro and to improve efficacy of hESC-cardiomyocyte grafts in infarcted athymic rat hearts. Epicardial cells markedly enhanced the contractility, myofibril structure and calcium handling of human engineered heart tissues, while reducing passive stiffness compared with mesenchymal stromal cells. Transplanted epicardial cells formed persistent fibroblast grafts in infarcted hearts. Cotransplantation of hESC-derived epicardial cells and cardiomyocytes doubled graft cardiomyocyte proliferation rates in vivo, resulting in 2.6-fold greater cardiac graft size and simultaneously augmenting graft and host vascularization. Notably, cotransplantation improved systolic function compared with hearts receiving either cardiomyocytes alone, epicardial cells alone or vehicle. The ability of epicardial cells to enhance cardiac graft size and function makes them a promising adjuvant therapeutic for cardiac repair.: This work was supported by the British Heart Foundation (BHF; Grants NH/11/1/28922, G1000847, FS/13/29/30024 and FS/18/46/33663), Oxford-Cambridge Centre for Regenerative Medicine (RM/13/3/30159), the UK Medical Research Council (MRC) and the Cambridge Hospitals National Institute for Health Research Biomedical Research Centre funding (SS), as well as National Institutes of Health Grants P01HL094374, P01GM081619, R01HL12836 and a grant from the Fondation Leducq Transatlantic Network of Excellence (CEM).

Convalescent plasma in patients admitted to hospital with COVID-19 (RECOVERY): a randomised controlled, open-label, platform trial

SummaryBackground Azithromycin has been proposed as a treatment for COVID-19 on the basis of its immunomodulatoryactions. We aimed to evaluate the safety and efficacy of azithromycin in patients admitted to hospital with COVID-19.Methods In this randomised, controlled, open-label, adaptive platform trial (Randomised Evaluation of COVID-19Therapy [RECOVERY]), several possible treatments were compared with usual care in patients admitted to hospitalwith COVID-19 in the UK. The trial is underway at 176 hospitals in the UK. Eligible and consenting patients wererandomly allocated to either usual standard of care alone or usual standard of care plus azithromycin 500 mg once perday by mouth or intravenously for 10 days or until discharge (or allocation to one of the other RECOVERY treatmentgroups). Patients were assigned via web-based simple (unstratified) randomisation with allocation concealment andwere twice as likely to be randomly assigned to usual care than to any of the active treatment groups. Participants andlocal study staff were not masked to the allocated treatment, but all others involved in the trial were masked to theoutcome data during the trial. The primary outcome was 28-day all-cause mortality, assessed in the intention-to-treatpopulation. The trial is registered with ISRCTN, 50189673, and ClinicalTrials.gov, NCT04381936.Findings Between April 7 and Nov 27, 2020, of 16 442 patients enrolled in the RECOVERY trial, 9433 (57%) wereeligible and 7763 were included in the assessment of azithromycin. The mean age of these study participants was65·3 years (SD 15·7) and approximately a third were women (2944 [38%] of 7763). 2582 patients were randomlyallocated to receive azithromycin and 5181 patients were randomly allocated to usual care alone. Overall,561 (22%) patients allocated to azithromycin and 1162 (22%) patients allocated to usual care died within 28 days(rate ratio 0·97, 95% CI 0·87–1·07; p=0·50). No significant difference was seen in duration of hospital stay (median10 days [IQR 5 to >28] vs 11 days [5 to >28]) or the proportion of patients discharged from hospital alive within 28 days(rate ratio 1·04, 95% CI 0·98–1·10; p=0·19). Among those not on invasive mechanical ventilation at baseline, nosignificant difference was seen in the proportion meeting the composite endpoint of invasive mechanical ventilationor death (risk ratio 0·95, 95% CI 0·87–1·03; p=0·24).Interpretation In patients admitted to hospital with COVID-19, azithromycin did not improve survival or otherprespecified clinical outcomes. Azithromycin use in patients admitted to hospital with COVID-19 should be restrictedto patients in whom there is a clear antimicrobial indication

Engineering a Novel Device to Implement Afterload on Human Stem Cell-Derived Cardiac Tissues

Thesis (Master's)--University of Washington, 2015Cardiac tissue engineering is a promising approach towards regenerating healthy myocardium and restoring the function of infarcted hearts. Using human embryonic stem cell (hESC) derived cardiomyocytes seeded in a collagen or fibrin scaffold, we have previously been able to generate engineered heart tissues (EHTs) that spontaneously contract, but with an amplitude that is far inferior to that of the native myocardium. In order to improve tissue maturation, our goal is to exercise and strengthen EHTs by applying the same mechanical load that the left ventricle faces during contractions—cardiac afterload. My investigation focuses on designing, building, and optimizing a device to apply cardiac afterload on hESC-EHTs. The afterload system involves anchoring tissues between two flexible posts made from polydimethylsiloxane: a rigid post that positions the tissue, and a flexible post containing a neodymium cube magnet that can be manipulated by an external bar magnet. The device is capable of providing a tunable resistance to tissue contractions that models the levels of afterload occurring in the developing heart at particular time points. We tested the load and rate dependency of afterload conditioning on constructs and found that tissues treated with afterload displayed 12.5-fold higher active stresses compared to unloaded controls, and were comparable with tissues undergoing isometric contractions (i.e. infinite afterload). The afterload device has provided us with an insight into the role of mechanical stimuli in promoting the maturation of hESC-EHTs. Our findings suggest that both static loads at 2 and 4 kPa, and steady increases in resistive loads from 0 to 8 kPa do not promote tissue contractility compared with isometric controls. Future work includes testing different static and dynamic loading regimes to identify the optimum level of afterload to promote construct maturation. In summary, we were able to engineer a novel system that applies physiological levels of afterload onto hESC-EHTs. With this new system, we performed the first studies to investigate the role of afterload conditioning in promoting the maturation of hESC-EHTs

From birth till palatoplasty: Prosthetic procedural limitations and safeguarding infants with palatal cleft

The most imminent issue to be addressed in a child born with cleft lip and/or palate is restoration of normal feeding. Early surgical treatment for cleft repair is crucial but may need to be postponed until certain age and weight gain is attained in an infant. When other feeding interventions fail in these children, prosthetic obturation of the defect with feeding instructions in the interim period is indicated to ward off the prevailing concerns. However, the entire prosthetic management presents a significant challenge with respect to the child's age, scope of iatrogenic injury to the delicate oral tissues, and potential for life-threatening situation during the procedures. This article draws attention toward preemptive measures which should be undertaken in the clinical setting during the fabrication of obturator to ascertain a desirable outcome without experiencing a grave complication that may arise due to ignorance and/or lack of facilities

Presentation of GIST as jejuno-jejunal intussusception

Gastrointestinal stromal tumours (GISTs) are rare tumour. It comprises 0.2% of gastrointestinal tumours and only 0.04% of small intestinal tumours. Usually this tumour is found in people in their 60s.These tumours can be found anywhere in the gastrointestinal tract but most commonly found in the stomach (40–60%). Patients with GISTs usually have vague and nonspecific symptoms. We present a 17year-old with complain of abdominal pain, distension, and few episodes of vomiting. All laboratory investigations were normal. The ultrasonography (USG) and computed tomography (CT) were suggestive of jejuno-jejunal intussusception. The patient had emergency exploratory laparotomy with resection of the segment with five cm healthy margin, and end to end anastomosis. Patient was discharged after 4 days and remains well. This case report highlights the rarity of GISTs in the concern of age (17 year old), site (Jejunum) as well as presentation (intussusception)
