BACKGROUND: Patients with depression require treatment continuity when discharged from inpatient care. Interventions aimed at optimizing transition into outpatient care may be effective in preventing symptom deterioration and readmission. We aimed to evaluate the effectiveness of care transition interventions for patients with depression after psychiatric hospitalization. METHODS: Systematic review and random-effects meta-analysis of controlled trials. Primary outcomes were readmissions and symptoms of depression...

Singlet oxygen, O2(a(1)Δg), the lowest excited electronic state of molecular oxygen, is an omnipresent part of life on earth. It is readily formed through a variety of chemical and photochemical processes, and its unique reactions are important not just as a tool in chemical syntheses but also in processes that range from polymer degradation to signaling in biological cells. For these reasons, O2(a(1)Δg) has been the subject of intense activity in a broad distribution of scientific fields for the past ∼50 years...

OBJECTIVE: Analyses focus on whether self-reported reasons for drinking alcohol change in their associations with high-intensity drinking across the transition to adulthood. METHOD: Self-report data on high-intensity drinking (10+ drinks) collected from the national Monitoring the Future study in 2005 to 2014 from those ages 18-26 were used (N = 2,664 [60% women] for all drinkers and 1,377 for heavy episodic [5+] drinkers; up to 6,541 person-waves). Time-varying effect modeling examined changes in the direction and magnitude of associations between eight reasons for drinking and high-intensity alcohol use across continuous age...

Direct dynamics simulations were performed to study the SN2 double inversion mechanism SN2-DI, with retention of configuration, for the F(-) + CH3I reaction. Previous simulations identified a transition state (TS) structure, i.e. TS0, for the SN2-DI mechanism, including a reaction path. However, intrinsic reaction coordinate (IRC) calculations from TS0 show it is a proton transfer (PT) TS connected to the F(-)HCH2I SN2 pre-reaction complex and the FHCH2I(-) proton transfer post-reaction complex. Inclusion of TS0 in the SN2-DI mechanism would thus involve non-IRC atomistic dynamics...

We have studied temperature-induced superionic phase transition in Li2S, which is one of the most promising Li-S battery cathode material. Concentration of ionic carriers at low and high temperature was evaluated from thermodynamics of defects (using density functional theory) and detailed balance condition (using ab initio molecular dynamics (AIMD)), respectively. Diffusion coefficients were also obtained using AIMD simulations. Calculated ionic conductivity shows that superionic phase transition occurs at T = 900 K, which is in agreement with reported experimental values...

The evolution of dislocation configurations in a new Ni-base single crystal superalloy, M4706, during tensile deformation at room temperature is characterised by transmission electron microscopy. Experimental results show that contrary to previous reports, numerous isolated superlattice stacking faults and extended stacking faults are formed in the slightly deformed specimens with and without tertiary γ' precipitates. Meanwhile, it is also found that as the plastic deformation proceeds, the dominant deformation mechanism changes from stacking fault shearing to antiphase boundary shearing...

Epithelial to mesenchymal transition (EMT) is a developmental program reactivated by tumor cells that leads to the switch from epithelial to mesenchymal phenotype. During EMT, cells are transcriptionally regulated to decrease E-cadherin expression while expressing mesenchymal markers such as vimentin, fibronectin and N-cadherin. Growing body of evidences suggest that cells engaged in EMT undergo a metabolic reprograming process, redirecting glucose flux toward Hexosamine Biosynthesis Pathway (HBP) which fuels aberrant glycosylation patterns that are extensively observed in cancer cells...

BACKGROUND: Regular follow-up care is essential for childhood cancer survivors, but we know little about physicians' experience with it. We aimed to describe: (1) involvement of Swiss physicians in follow-up care; (2) content of follow-up care provided; (3) problems encountered; and (4) additional resources needed. MATERIALS AND METHODS: Within this cross-sectional survey we sent adapted questionnaires via professional associations to a sample of medical oncologists (MOs), paediatric oncologists (POs), general practitioners (GPs) and paediatricians (P) in Switzerland...

INTRODUCTION: Musculoskeletal (MSK) complaints are the second most common reason for a hospital outpatient appointment in the US, and account for 19.5% of general practice consultations. Previous studies have shown that passive teaching in medical school does not imbue students with an adequate degree of confidence in MSK evaluation. The aim of this study was to conduct a randomized control trial to compare the effect of the gold standard small group tutorial of bedside teaching against case-based teaching (CBT) in relation to orthopedic surgery in medical students...

BACKGROUND: Pediatric chronic kidney disease is psychologically, financially, and physically demanding on parents providing care. Parents often feel isolated because of the rarity of the condition, and geographic isolation often compounds this perception in Canada. Many parents seek assistance online for both information and social support. OBJECTIVE: This study examines an online portal, titled "Ability Online," which was designed to provide support and information to a diverse group of parents using chat facilities, bulletin boards, and e-mail...

Adaptive behavior requires context-sensitive configuration of task-sets that specify time-varying stimulus-response mappings. Intriguingly, response time costs associated with changing task-sets and motor responses are known to be strongly interactive: switch costs at the task-level are small in the presence of a response-switch but large when accompanied by a response-repetition, and vice versa for response-switch costs. The reasons behind this well-known inter-dependence between task- and response-level control processes are currently not well understood...

Nidotherapy is a new form of psychological therapy that aims to improve mental health by a systematic and collaborative manipulation of the environment in all its forms without focusing on alleviation of symptoms. Following treatment with nidotherapy, we describe a dramatic, and continuing, improvement in a woman with comorbid severe depressive illness and borderline personality disorder. She had made repeated serious suicide attempts over the previous 25 years and had received many drug and psychological treatments without success...

INTRODUCTION: Human immunodeficiency virus/acquired immune deficiency syndrome (HIV/AIDS) is one of the most prevalent infectious diseases in the border region of Mexico due to the flow of migrants under desperate conditions, encouraging casual and unprotected sex. Since this has become a binational public health problem, it is important to understand the factors that predict these sexual behaviors. The aim of the current study was to investigate the facilitators and inhibitors of transition in the sexual behavior of migrants from two border regions on the Mexico-United States (US) border...

Science education plays a critical role as political priority due to its fundamental importance in engaging students to pursue technological careers considered essential in modern societies, in order to face scientific development challenges. High-level achievement on science education and positive attitudes toward science constitutes a crucial challenge for formal education. Several studies indicate close relationships between students' attitudes, cognitive abilities, and academic achievement. The main purpose of this study is to analyze the impact of student's attitudes toward the school discipline of Physics and Chemistry and their reasoning abilities on academic achievement on that school subject, among Portuguese 9th grade students using the data collected during the Project Academic Performance and Development: a longitudinal study on the effects of school transitions in Portuguese students (PTDC/CPE-CED/104884/2008)...

Mitral valve regurgitation (MR) is a disorder of the heart in which the mitral valve does not close properly. This causes an abnormal leaking of blood backwards from the left ventricle into the left atrium during the systolic contractions of the left ventricle. Noninvasive assessment of MR using echocardiography is an ongoing challenge. In particular, a major problem are eccentric or Coanda regurgitant jets which hug the walls of the left atrium and appear smaller in the color Doppler image of regurgitant flow...

Medical education has been under a constant state of revision for the past several years. The overarching theme of the curriculum revisions for medical schools across the USA has been creating better physicians for the 21st century, with the same end result: graduating medical students at the optimal performance level when entering residency. We propose a robust, thorough assessment process that will address the needs of clerkships, residents, students, and, most importantly, medical schools to best measure and improve clinical reasoning skills that are required for the learning outcomes of our future physicians...

Two groundbreaking reports were published in Acta Cytologica at the transition of 1976 to 1977. One appeared in the last issue of 1976 [Meisels and Fortin: Acta Cytol 1976;20:505-509] and the other in the first issue of 1977 [Purola and Savia: Acta Cytol 1977;21:26-31]. Today, 40 years later, it is not an overstatement to conclude that these are the two most influential studies ever published in this journal. Two reports with a similar content being published so close together (in the same journal) raised the question "Which of the two reports was truly submitted first?" In this commentary, this enigma is clarified beyond reasonable doubt, based on the well-considered testimonial of Prof...

Mechanisms of excited-state intramolecular proton transfer (ESIPT) of 1,2-dihydroxyanthraquinone (ALR) in ethanol solvent and binary solvent of water and ethanol are investigated using the density functional theory (DFT) and time-dependent density functional theory (TDDFT). The intramolecular hydrogen bond is found to be reinforced in the excited state based on the bond lengths, bond angles and infrared (IR) vibrational spectra of relevant group. The reinforcement of intramolecular hydrogen bond is attributed to the charge transfer in the excited state, which leads to the ESIPT to form a keto isomer...

The search for small molecule inhibitors has gained prominence with the recognition of their inherent advantage for cancer therapy. Combretastatin is a naturally occurring small stilbenoid. By virtue of the ability to bind to tubulin combretastatin and its derivatives promote depolymerisation of microtubules as well as inhibit tubulin polymerisation. This suppresses cell proliferation signalling and induces apoptosis. Combretastatins activate mitotic checkpoints that lead to mitotic catastrophe and apoptosis...

BACKGROUND: Neuroendocrine tumors of the neck are rare swellings, which constitute about 0.03% of all tumors. Most are sporadically arising paragangliomas. Over 50% arise from the carotid bodies and pose difficulties in diagnosis and surgical management, which may result in disabling complications. OBJECTIVE: To determine the diagnostic, surgical and postoperative challenges, and how to overcome them, in the management of neuroendocrine tumors of the neck. STUDY DESIGN: Descriptive case series...
