Adolescent association with deviant and delinquent friends was examined for its roots in coercive parent–teen interactions and its links to functional difficulties extending beyond delinquent behavior and into adulthood. A community sample of 184 adolescents was followed from age 13 to age 27, with collateral data obtained from close friends, classmates, and parents. Even after accounting for adolescent levels of delinquent and deviant behavior, association with deviant friends was predicted by coercive parent–teen interactions and then linked to declining functioning with peers during adolescence and greater internalizing and externalizing symptoms and poorer overall adjustment in adulthood. Results are interpreted as suggesting that association with deviant friends may disrupt a core developmental task—establishing positive relationships with peers—with implications that extend well beyond deviancy-training effects.
We aimed to critically evaluate decision aids developed for practitioners and caregivers when providing care for someone with dementia or for use by people with dementia themselves. Decision aids may be videos, booklets, or web-based tools that explicitly state the decision, provide information about the decision, and summarize options along with associated benefits and harms. This helps guide the decision maker through clarifying the values they place on the benefits or harms of the options.
We conducted a systematic review of peer-reviewed literature in electronic databases (CINAHL, The Cochrane Library, EMBASE, MEDLINE, and PsychINFO) in March 2018. Reference lists were searched for relevant papers and citations tracked. Data were synthesized with meta-analysis and narrative synthesis. Papers were included if they met the following criteria: 1) the focus of the paper was on the evaluation of a decision aid; 2) the decision aid was used in dementia care; and 3) the decision aid was aimed at professionals, people with dementia, or caregivers.
We identified 3618 studies, and 10 studies were included, covering three topics across six decision aids: 1) support with eating/feeding options, 2) place of care, and 3) goals of care. The mode of delivery and format of the decision aids varied and included paper-based, video-based, and audio-based decision aids. The decision aids were shown to be effective, increasing knowledge and the quality of communication. The meta-analysis demonstrated that decisions are effective in reducing decisional conflict among caregivers (standardized mean difference = −0.50, 95% confidence interval [ − 0.97, − 0.02]).
Decision aids offer a promising approach for providing support for decision-making in dementia care. People are often faced with more than one decision, and decisions are often interrelated. The decision aids identified in this review focus on single topics. There is a need for decision aids that cover multiple topics in one aid to reflect this complexity and better support caregivers.
Palliative care and the hospice movement were founded as a response to people dying from cancer . However, there is now wide recognition that palliative care should be provided and made available for people with a range of progressive advanced chronic diseases including dementia, frailty and organ failure. This is particularly pertinent as the population ages and a growing number of people are dying with these conditions. This chapter defines palliative care and the role of the psychiatrist, and examines some current issues in palliative care including having difficult conversations, dealing with uncertainty, symptom control and supporting grieving family and friends both before and after death, with a focus on the needs of those with dementia.
Filarial nematodes possess glutathione transferases (GSTs), ubiquitous enzymes with the potential to detoxify xenobiotic and endogenous substrates, and modulate the host immune system, which may aid worm infection establishment, maintenance and survival in the host. Here we have identified and characterized a σ class glycosylated GST (OoGST1), from the cattle-infective filarial nematode Onchocerca ochengi, which is homologous (99% amino acid identity) with an immunodominant GST and potential vaccine candidate from the human parasite, O. volvulus, (OvGST1b). Onchocerca ochengi native GSTs were purified using a two-step affinity chromatography approach, resolved by 2D and 1D SDS-PAGE and subjected to enzymic deglycosylation revealing the existence of at least four glycoforms. A combination of lectin-blotting and mass spectrometry (MS) analyses of the released N-glycans indicated that OoGST1 contained mainly oligomannose Man5GlcNAc2 structure, but also hybrid- and larger oligommanose-type glycans in a lower proportion. Furthermore, purified OoGST1 showed prostaglandin synthase activity as confirmed by Liquid Chromatography (LC)/MS following a coupled-enzyme assay. This is only the second reported and characterized glycosylated GST and our study highlights its potential role in host-parasite interactions and use in the study of human onchocerciasis.
Reductions in insulin sensitivity in periparturient dairy cows develop as a means to support lactation; however, excessive mobilization of fatty acids (FA) increases the risk for peripartal metabolic disorders. Our objectives were to investigate the effect of prepartum body condition score (BCS) on systemic glucose and insulin tolerance, and to compare direct and indirect measurements of insulin sensitivity in peripartal lean and overweight dairy cows. Fourteen multiparous Holstein cows were allocated into two groups according to their BCS at day −28 prepartum: lean (n = 7; BCS ≤ 3.0) or overweight; (n = 7; BCS ≥ 4.0). Liver biopsies were performed on day −27, −14 and 4, relative to expected parturition. Intravenous insulin or glucose tolerances tests were performed following each liver biopsy. Relative to lean cows, overweight cows exhibited lower dry matter intake, lost more BCS and displayed increased plasma FA and β-hydroxybutyrate concentrations and elevated liver lipid content during peripartum. Glucose clearance rate was lower for all cows postpartum. Prepartum BCS had minimal effects on insulin and glucose tolerance; however, the ability of the cow to restore blood glucose levels following an insulin challenge was suppressed by increased BCS. Glucose-dependent parameters of insulin and glucose tolerance were not correlated with surrogate indices of insulin sensitivity. We conclude that prepartum BCS had minimal effect on systemic insulin sensitivity following parturition. The observed inconsistency between surrogate indices of insulin sensitivity and direct measurements of insulin and glucose tolerance adds support to growing concerns regarding their usefulness as tools to estimate systemic insulin action in periparturient cows.
