We report a functional switching valve within the female genitalia of the Brazilian cave insect Neotrogla . The valve complex is composed of two plate-like sclerites, a closure element, and in-and-outflow canals. Females have a penis-like intromittent organ to coercively anchor males and obtain voluminous semen. The semen is packed in a capsule, whose formation is initiated by seminal injection. It is not only used for fertilization but also consumed by the female as nutrition. The valve complex has two slots for insemination so that Neotrogla can continue mating while the first slot is occupied...

BACKGROUND: Several advances have led to improved hospital survival following neonatal palliation (NP) of single ventricle (SV) anomalies. Nonetheless, a number of patients continue to suffer from interstage mortality (ISM) prior to subsequent Glenn. We aim to study patients' characteristics and anatomic, surgical, and clinical details associated with ISM. METHODS: A total of 453 SV neonates survived to hospital discharge following NP. Competing risk analysis modeled events after NP (Glenn, transplantation, or death) and examined variables associated with ISM...

Photoluminescent mechanisms in erbium-doped barium titanate nanoparticle systems were studied. Er3+ ions were introduced into the BaTiO₃ lattice by the sol-gel method. The resulting Er3+ concentration was between 0% and 5%, with Ba/Ti ratios of 1.008 and 0.993. The stoichiometry of Ba and Ti concentrations in the lattice influenced the doping mechanism and placement of erbium ions in the lattice structure. Our research shows the existence of a strong correlation between Ba/Ti ratios, erbium concentration, phase structure and doping site location on the upconversion photoluminescence mechanisms...

Cancer is a highly intelligent system of cells, that works together with the body to thrive and subsequently overwhelm the host in order for its survival. Therefore, treatment regimens should be equally competent to outsmart these cells. Unfortunately, it is not the case with current therapeutic practices, the reason why it is still one of the most deadly adversaries and an imposing challenge to healthcare practitioners and researchers alike. With rapid nanotechnological interventions in the medical arena, the amalgamation of diagnostic and therapeutic functionalities into a single platform, theranostics provides a never before experienced hope of enhancing diagnostic accuracy and therapeutic efficiency...

Brucellosis is a highly contagious and zoonotic disease and has a considerable impact on animal health and economy of a country, principally in Pakistan, where rural income largely depends upon livestock farming and dairy products. The disease burden is more in underdeveloped/developing countries due to the low economy and limited access to the diagnostic facilities. In Pakistan, the prevalence of Brucella abortus is very high, so it is the need of the hour to control this disease through more advanced methods...

Background: Obesity is a risk factor for de novo chronic kidney disease (CKD) in the general population. Obesity has been increasingly prevalent in patients with CKD and may lead to further progression of pre-existing CKD. However, whether obesity is associated with the development of end-stage renal disease (ESRD) in patients with CKD is not well understood. Objective: We investigated the impact of obesity on ESRD (needing chronic dialysis treatment or pre-emptive renal transplantation) or all-cause mortality in patients with moderate to advanced CKD...

BACKGROUND: Kenya has experienced outbreaks of chikungunya in the past years with the most recent outbreak occurring in Mandera in the northern region in May 2016 and in Mombasa in the coastal region from November 2017 to February 2018. Despite the outbreaks in Kenya, studies on vector competence have only been conducted on Aedes aegypti. However, the role played by other mosquito species in transmission and maintenance of the virus in endemic areas remains unclear. This study sought to determine the possible role of rural Aedes bromeliae and Aedes vittatus in the transmission of chikungunya virus, focusing on Kilifi and West Pokot regions of Kenya...

The purpose of the study was to analyse the remote results of bypass grafting for myocardial bridges. Our retrospective single-centre study included a total of 17 patients subjected to coronary bypass grafting of the anterior descending artery (ADA) in connection with a detected myocardial bridge (MB). All patients underwent assessment of the coronary bypass grafts (CBG) by means of intraoperative flowmetry - transit time flow measurement (TTFM), as well as angiographic control of the CBGs in the remote period...

The authors examined the effect of the presence of undifferentiated connective tissue dysplasia (UCTD) on the clinical course of lower-limb varicose veins (LLVV) and acute varicothrombophlebitis (AVTP) in patients after the Troyanov-Trendelenburg operation. We carried out a prospective comparative study of the remote results during three years after the Troyanov-Trendelenburg operation in a total of 132 patients suffering from AVTP. The Study Group included 67 patients found to have more than four phenotypic traits of UCTD, thus suggesting the presence of UCTD...

Transgender people experience interpersonal and structural barriers which prevent them from accessing culturally and medically competent health care. This rapid systematic review examined the prevalence of health-care discrimination among transgender people in the U.S. and drew comparisons with sexual minority samples and the general U.S. population. Eight primary studies with 35 prevalence estimates were analyzed. Transgender populations experience profound rates of discrimination within the U.S. health-care system...

The downstream demand for professionals with competence in Interprofessional Collaboration (IPC) has contributed to the substantial growth in the upstream demand for interprofessional education (IPE). The majority of IPE programs focuses exclusively on direct care practitioners and seldom include those responsible for the administration and management of care. Unfortunately, complex reimbursement mechanisms along with the multiple agencies and departments regulating the delivery, evaluation, and reimbursement of care can result in unintended barriers to IPC and eventually IPE...

The involvement of patients and carers is central to the values of interprofessional education (IPE) which aims to improve the experience of care and care delivery. Partnership arrangements with service users and carers within Higher Education Institutions face the same barriers relating to status, power, and resources, as the implementation of IPE. The complexity of these alignments can be explained by Activity Theory (AT). Using a qualitative research methodology we set out to consider the stakeholder perspectives on whether patients should progress from telling their stories to taking on a leading teaching role, within a well-established IPE workshop...

The Nelson Mandela University in Port Elizabeth, South Africa, seeks to transform its health professions curricula in order to achieve equity in health outcomes. Integral to this are interprofessional education service-learning initiatives attendant to socially accountable objectives. We describe one such initiative, the Zanempilo Mobile Health Education Platform (MHEP), which engages interprofessional healthcare students and faculty members in delivering health services to underserved communities. The Zanempilo MHEP consists of a converted 13-ton truck as a mobile clinic from where student-run services are provided...

Patients and their families have expressed that they want information (Hendricks, 2000) and as a result often turn to Google for health and medical information. Society as a whole is more informed than ever and no longer rely only on medical practitioners as in previous generations. Instead, and rightly so, they question medical experts and want to know the reasoning and rationale behind everything they experience. This combined with the shift towards family-centred principles over the last 20 years underscores the need to provide comprehensive and effective education to families...

PROBLEM: The traditional clerkship model of brief encounters between faculty and students results in reduced meaningful learning opportunities due to the lack of a relationship that enables repeated observation, supervisor feedback, trust formation, and growth. INTERVENTION: Clinical clerkships at our institution were restructured to decrease fragmentation of supervision and foster an educational alliance between faculty and student. A mixed-methods approach was used to study the impact of this curriculum reform on the student experience in the obstetrics and gynecology clerkship...

Demands for change in a relationship, particularly when met by behavioral withdrawal, foreshadow declines in relationship satisfaction. Yet demands can give partners opportunities to voice concerns, and withdrawal can serve to de-escalate conflict, stabilizing satisfaction instead (e.g., Overall, Fletcher, Simpson, & Sibley, 2009). We aim to reconcile these competing possibilities by arguing that withdrawal in response to requests for change will be detrimental among couples who possess the social, educational, and economic capital needed to address these requests, whereas withdrawal in response to partner demands will be constructive among couples with fewer resources for making the requested changes...

A recurrent observation in personality judgments is that individuals' ratings of others' personalities are positively linked to their self-description, and that such "assumed similarity" effects appear to be trait-specific. However, the extent of and explanations for assumed similarity have been addressed only insufficiently. To close this gap, we first provide a meta-analytic summary of evidence on assumed similarity of basic personality traits. More importantly, we then critically test different theoretical accounts of assumed similarity (i...
