Mental wellbeing during pregnancy and the year after birth is critical to a range of maternal and infant outcomes. Many mental health interventions fail to incorporate stakeholder perspectives. The Catalyst Project aimed to work with key stakeholders in Mozambique to develop interventions and delivery strategies which were in-line with existing evidence and the needs, goals, and priorities of those both directly and indirectly involved in its success.
 
  A qualitative, human-centred design approach was utilised. Focus-group discussions, individual interviews, and observations with young women (aged 16-24 years), their families, community leaders, service providers and government were used to better understand the needs, priorities and challenges to mental wellbeing of young women. These findings were triangulated with the literature to determine priority challenges to be addressed by an intervention. Stakeholder workshops were held to identify potential solutions and co-develop an intervention and delivery stors for maternal mental disorders in a way that appeals to them, their families and service providers. By using human-centred design to understand the needs and priorities of young mothers and the health and community systems in which they live, the resulting intervention and delivery strategy is one that stakeholders view as appropriate and acceptable.
 We have developed an intervention to reduce the risk of poor maternal mental health and gives young mothers hope and skills to make a better life for them and their children by packaging information about the risk and protective factors for maternal mental disorders in a way that appeals to them, their families and service providers. By using human-centred design to understand the needs and priorities of young mothers and the health and community systems in which they live, the resulting intervention and delivery strategy is one that stakeholders view as appropriate and acceptable.
  Pulmonary hypertension (PH) is a life-threatening progressive disease with high mortality in the elderly. However, the pathogenesis of PH has not been fully understood and there is no effective therapy to reverse the disease process. This study aims to determine whether cellular senescence is involved in the development of PH.
 
  The rat PH model was established by intraperitoneal injection of monocrotaline and evaluated by pulmonary arteriole wall thickness and right ventricular hypertrophyindex. Human lung fibroblasts (HLFs) were treated with CoCl
  or hypoxia to induce cellular senescence in vitro. SA-β-gal staining and the changes of senescent markers were used to examine cellular senescence. The molecular mechanism of cellular senescence was further explored by detecting reactive oxygen species (ROS) levels and culturing cells with a conditioned medium.
 
  We revealed the cellular senescence of pulmonary adventitial fibroblasts in vivo in the rat PH model. The expression of Bmi-1, an important regulator of senescence, was decreased in the lungs of PH rats and localized in adventitial fibroblasts.  https://www.selleckchem.com/products/fhd-609.html  The in vitro experiments showed that p16 expression was increased while Bmi-1 expression was decreased after CoCl
  treatment in HLFs. Mechanistically, Bmi-1 could alleviate CoCl
  -induced HLFs senescence by eliminating ROS which further promoted the proliferation of pulmonary artery smooth muscle cells by paracrine mode of action of HLFs.
 
  Bmi-1 alleviates the cellular senescence of pulmonary fibroblasts in PH, which expands the pathogenesis of PH and provides a theoretical basis for targeting senescent cells in the treatment of PH.

  Tobacco smoking using a hookah (i.e., waterpipe) is a global epidemic. While evidence suggests that sexual minorities (SM) have higher odds of hookah use compared to heterosexuals, little is known about their hookah use patterns and transitions. We sought to examine transitions between hookah smoking and use of other tobacco and electronic (e-) products among SM adults aged 18 years of age and older versus their heterosexual counterparts.
 
  We analyzed nationally representative data of ever and current hookah smokers from Wave 1 (2013-2014; ever use n = 1014 SM and n = 9462 heterosexuals; current use n = 144 SM and n = 910 heterosexuals) and Wave 2 (2014-2015; ever use n = 901 SM and n = 8049 heterosexuals; current use n = 117 SM and n = 602 heterosexuals) of the Population Assessment of Tobacco and Health Study. Comparisons between groups and gender subgroups within SM identity groups were determined with Rao-Scott chi-square tests and multivariable survey-weighted multinomial logistic regression models weookah as well as vaping, specifically tailored among SM communities.
 Compared to heterosexuals, in addition to higher rates of hookah smoking, higher percentages of SM adults transitioned to hookah plus e-product use between 2013 and 2015. Results have implications for stronger efforts to increase awareness of the harmful effects of hookah as well as vaping, specifically tailored among SM communities.
  Sniffer dogs are able to detect certain chemical particles and are suggest to be capable of helping diagnose some medical conditions and complications, such as colorectal cancer, melanoma, bladder cancer, and even critical states such as hypoglycemia in diabetic patients. With the global spread of COVID-19 throughout the world and the need to have a real-time screening of the population, especially in crowded places, this study aimed to investigate the applicability of sniffer dogs to carry out such a task.
 
  Firstly, three male and female dogs from German shepherd (Saray), German black (Kuzhi) and Labrador (Marco) breeds had been intensively trained throughout the classical conditioning method for 7 weeks. They were introduced to human specimens obtained from the throat and pharyngeal secretions of participants who were already reported positive or negative for SARS-COV-2 infection be RT-PCR. Each dog underwent the conditioning process for almost 1000 times. In the meantime another similar condition process was conducted on clothes and masks of COVID-19 patient using another three male and female dogs from Labrador (Lexi), Border gypsy (Sami), and Golden retriever (Zhico) breeds.
