The prevalence and correlates of depression, anxiety, and stress in a sample of college students

Author: Beiter, R.; Nash, R.; McCrady, M.; Rhoades, D.; Linscomb, M.; Clarahan, M.; Sammut, S. Description: BACKGROUND: Over the past four years, the Franciscan University Counseling Center has reported a 231% increase in yearly visits, as well as a 173% increase in total yearly clients. This trend has been observed at many universities as mental health issues pose significant problems for many college students. The objective of this study was to investigate potential correlates of depression, anxiety, and stress in a sample of college students. METHODS: The final analyzed sample…

The impact of episodic and chronic poverty on child cognitive development

Author: Najman, J.M.; Hayatbakhsh, M.R.; Heron, M.A.; Bor, W.; O’Callaghan, M.J.; Williams, G.M. Description: OBJECTIVE: To determine whether changes in family poverty between pregnancy, early childhood, and adolescence predict child cognitive development at 14 years of age. STUDY DESIGN: We conducted a population-based prospective birth cohort study of 7223 mothers who gave birth to a live singleton baby, observed to 14 years of age. Family income was measured on 4 occasions from pregnancy to the 14-year follow-up. Child cognitive development was measured at the 14-year follow-up using the Raven’s Standard…

The impact of commodity price and conservation policy scenarios on deforestation and agricultural land use in a frontier area within the Amazon

Author: Verburg, Rene; Filho, Saulo Rodrigues; Lindoso, Diego; Debortoli, Nathan; Litre, Gabriela; Bursztyn, Marcel Description: Deforestation in the Amazon is caused by the complex interplay of different drivers. Price of commodities such as beef and soya, and incoming migration are paramount factors. Construction of new highways is a key aspect, as they enable a growing flow of people and economic activities, provoking an intensification of the conversion of forests into pasture and agricultural areas. The pavement of road BR-163 accelerates the expansion of the agricultural frontier from the state of…

Development of a transmission-blocking malaria vaccine: progress, challenges, and the path forward

Author: Nunes, Julia K.; Woods, Colleen; Carter, Terrell; Raphael, Theresa; Morin, Merribeth J.; Diallo, Diadier; Leboulleux, Didier; Jain, Sanjay; Loucq, Christian; Kaslow, David C.; Birkett, Ashley J. Description: New interventions are needed to reduce morbidity and mortality associated with malaria, as well as to accelerate elimination and eventual eradication. Interventions that can break the cycle of parasite transmission, and prevent its reintroduction, will be of particular importance in achieving the eradication goal. In this regard, vaccines that interrupt malaria transmission (VIMT) have been highlighted as an important intervention, including transmission-blocking…

Climates of fear and socio-political change

Author: Barbalet, J. M. Description: Argues that social and organizational change results from containment behavior in response to fear on the part of elite social groups. Relative power disparities frequently lead to this elite fear. Rather than fight or flight, containment is a significant fear response for both subordinate and elite groups, and when fear is seen to have a social object, the possibility of collective action to remove the source of fear can be recognized. Subject headings: Collective Behavior; Fear; Organizational Change; Social Change; Interpersonal Control; Political Processes Publication…

The choice of optimal parameters for measurement of spin-lattice relaxation times. II. Comparison of saturation recovery, inversion recovery, and fast inversion recovery experiments

Author: Becker, E.D.; Ferretti, J.A.; Gupta, R.K.; Weiss, G.H. Description: Using the theory developed in Part I of this series (1) we determine the optimum pulse spacings using saturation recovery, inversion recovery, fast inversion recovery, and Freeman-Hill techniques for the measurement of spin-lattice relaxation times, T1, for conditions of ideal 90° and 180° pulses. We also compare the performance of these techniques, using as the criterion the total experimental time required to reach a specified precision in the estimate of T1. The important assumptions made are (1) that an interval…

Memory function in very early Alzheimer’s disease

Author: Petersen, R.C.; Smith, G.E.; Ivnik, R.J.; Kokmen, E.; Tangalos, E.G. Description: The detection of very early Alzheimer’s disease (AD) can be important for both theoretical and practical reasons. Typically, a memory impairment is the first sign of incipient disease, but the early clinical diagnosis can be challenging. We investigated several aspects of memory function in AD and normal aging to determine which indices of performance were most sensitive at detecting early impairments. We evaluated 106 pairs of patients with probable AD and matched controls from the Mayo Clinic Alzheimer’s…

Can physicians conceive of performing euthanasia in case of psychiatric disease, dementia or being tired of living?

Author: Bolt, E.E.; Snijdewind, M.C.; Willems, D.L.; van der Heide, A.; Onwuteaka-Philipsen, B.D. Description: BACKGROUND: Euthanasia and physician-assisted suicide (EAS) in patients with psychiatric disease, dementia or patients who are tired of living (without severe morbidity) is highly controversial. Although such cases can fall under the Dutch Euthanasia Act, Dutch physicians seem reluctant to perform EAS, and it is not clear whether or not physicians reject the possibility of EAS in these cases. AIM: To determine whether physicians can conceive of granting requests for EAS in patients with cancer, another…

Molecular mechanisms of antibiotic resistance

Author: Blair, J.M.A.; Webber, M.A.; Baylay, A.J.; Ogbolu, D.O.; Piddock, L.J.V. Description: Antibiotic-resistant bacteria that are difficult or impossible to treat are becoming increasingly common and are causing a global health crisis. Antibiotic resistance is encoded by several genes, many of which can transfer between bacteria. New resistance mechanisms are constantly being described, and new genes and vectors of transmission are identified on a regular basis. This article reviews recent advances in our understanding of the mechanisms by which bacteria are either intrinsically resistant or acquire resistance to antibiotics, including…
