Withdrawal versus continuation of long-term antipsychotic drug use for behavioural and psychological symptoms in older people with dementia

Background : Antipsychotic agents are often used to treat neuropsychiatric symptoms (NPS) in people with dementia although there is uncertainty about the effectiveness of their long-term use for this indication and concern that they may cause harm, including higher mortality. When behavioural strategies have failed and treatment with antipsychotic drugs is instituted, regular attempts to withdraw them have been recommended in guidelines. Physicians, nurses and families of older people with dementia may be reluctant to stop antipsychotics, fearing deterioration of NPS. This is an update of a Cochrane Review published in 2013. Objectives : To evaluate whether withdrawal of antipsychotic agents is successful in older people with dementia and NPS in primary care or nursing home settings, to list the different strategies for withdrawal of antipsychotic agents in older participants with dementia and NPS, and to measure the effects of withdrawal of antipsychotic agents on participants' behaviour and assess safety. Search methods : We searched the Specialized Register of the Cochrane Dementia and Cognitive Improvement Group (ALOIS), the Cochrane Library, MEDLINE, Embase, PsycINFO, CINAHL, LILACS, clinical trials registries and grey literature sources up to 11 January 2018. Selection criteria : We included all randomised, controlled trials comparing an antipsychotic withdrawal strategy to continuation of antipsychotics in people with dementia who had been treated with an antipsychotic drug for at least three months. Data collection and analysis : We used standard methodological procedures according to the Cochrane Handbook for Systematic Reviews of Interventions. We rated the quality of evidence for each outcome using the GRADE approach. Main results : We included 10 studies involving 632 participants. One new trial (19 participants) was added for this update. One trial was conducted in a community setting, eight in nursing homes and one in both settings. Different types of antipsychotics at varying doses were discontinued in the studies. Both abrupt and gradual withdrawal schedules were used. Reported data were predominantly from studies at low or unclear risk of bias. We included nine trials with 575 randomised participants that used a proxy outcome for overall success of antipsychotic withdrawal. Pooling data was not possible due to heterogeneity of outcome measures used. Based on assessment of seven studies, discontinuation may make little or no difference to whether or not participants complete the study (low-quality evidence). Two trials included only participants with psychosis, agitation or aggression who had responded to antipsychotic treatment. In these two trials, stopping antipsychotics was associated with a higher risk of leaving the study early due to symptomatic relapse or a shorter time to symptomatic relapse. We found low-quality evidence that discontinuation may make little or no difference to overall NPS, measured using various scales (7 trials, 519 participants). There was some evidence from subgroup analyses in two trials that discontinuation may reduce agitation for participants with less severe NPS at baseline, but may be associated with a worsening of NPS in participants with more severe NPS at baseline. None of the studies assessed withdrawal symptoms. Adverse effects of antipsychotics (such as falls) were not systematically assessed. Low-quality evidence showed that discontinuation may have little or no effect on adverse events (5 trials, 381 participants), quality of life (2 trials, 119 participants), or cognitive function (5 trials, 365 participants). There were insufficient data to determine whether discontinuation of antipsychotics has any effect on mortality (very low-quality evidence). Authors' conclusions : There is low-quality evidence that antipsychotics may be successfully discontinued in older people with dementia and NPS who have been taking antipsychotics for at least three months, and that discontinuation may have little or no important effect on behavioural and psychological symptoms. This is consistent with the observation that most behavioural complications of dementia are intermittent and often do not persist for longer than three months. Discontinuation may have little or no effect on overall cognitive function. Discontinuation may make no difference to adverse events and quality of life. Based on the trials in this review, we are uncertain whether discontinuation of antipsychotics leads to a decrease in mortality. People with psychosis, aggression or agitation who responded well to long-term antipsychotic drug use, or those with more severe NPS at baseline, may benefit behaviourally from continuation of antipsychotics. Discontinuation may reduce agitation for people with mild NPS at baseline. However, these conclusions are based on few studies or small subgroups and further evidence of benefits and harms associated with withdrawal of antipsychotic is required in people with dementia and mild and severe NPS. The overall conclusions of the review have not changed since 2013 and the number of available trials remains low

Toward the optimal strategy for sustained weight loss in overweight cancer survivors:A systematic review of the literature

Purpose: To gain more insight into the optimal strategy to achieve weight loss and weight loss maintenance in overweight and obese cancer survivors after completion of initial treatment, this systematic review aimed to provide an overview of the literature on intervention effects on weight, to describe intervention components used in effective interventions, to identify and synthesize behaviour change techniques (BCTs) and to assess the frequency with which these BCTs were used in effective interventions. Methods: Six databases were searched for original research articles describing weight changes in adult overweight cancer survivors after participation in a lifestyle intervention initiated after completion of initial treatment. Two researchers independently screened the retrieved papers and extracted BCTs using the BCT Taxonomy version 1. Results: Thirty-two papers describing 27 interventions were included. Interventions that were evaluated with a robust study design (n = 8) generally showe

Synchronous and metachronous urothelial carcinoma of the upper urinary tract and the bladder: Are they clonally related? A systematic review

Purpose: Following radical nephroureterectomy for upper urinary tract urothelial carcinoma (UTUC), intravesical recurrence (IVR) is found in 22% to 47% of patients. Patients with a primary urothelial carcinoma of the bladder (UCB) have an increased risk of a future UTUC (1%–5%). Paired UTUC and UCB might represent clonally related tumors due to intraluminal seeding of tumor cells or might be separate entities of urothelial carcinoma caused by field cancerization. We systematically reviewed all the relevant literature to address the possible clonal relation of UTUC and paired UCB. Materials and Methods: MEDLINE, EMBASE, and COCHRANE databases were systematically searched for relevant citations published between January 2000 and July 2019. This study was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines. Of 5038 citations identified, 86 full papers were screened, and 9 studies met the inclusion criteria. Results: The populations studied and the molecular techniques used to assess clonality of UTUC and paired UCB differed largely over time. Eight studies reported on primary UTUC and meta- or synchronous IVR without a history of UCB. A total of 118 tumors

Combining HPAEC-PAD, PGC-LC-MS, and 1D ¹H NMR to Investigate Metabolic Fates of Human Milk Oligosaccharides in 1-Month-Old Infants:A Pilot Study

A solid-phase extraction procedure was optimized to extract 3-fucosyllactose and other human milk oligosaccharides (HMOs) from human milk samples separately, followed by absolute quantitation using high-performance anion-exchange chromatography-pulsed amperometric detection and porous graphitized carbon-liquid chromatography-mass spectrometry, respectively. The approach developed was applied on a pilot sample set of 20 human milk samples and paired infant feces collected at around 1 month postpartum. One-dimensional 1H nuclear magnetic resonance spectroscopy was employed on the same samples to determine the relative levels of fucosylated epitopes and sialylated (Neu5Ac) structural elements. Based on different HMO consumption patterns in the gastrointestinal tract, the infants were assigned to three clusters as follows: complete consumption; specific consumption of non-fucosylated HMOs; and, considerable levels of HMOs still present with consumption showing no specific preference. The consumption of HMOs by infant microbiota also showed structure specificity, with HMO core structures and Neu5Ac(α2-3)-decorated HMOs being most prone to degradation. The degree and position of fucosylation impacted HMO metabolization differently. </p

Improving Health Literacy Responsiveness:A Randomized Study on the Uptake of Brochures on Doctor-Patient Communication in Primary Health Care Waiting Rooms

Presenting attractive and useful health education materials in waiting rooms can help improve an organization's health literacy responsiveness. However, it is unclear to what extent patients may be interested in health education materials, such as brochures. We conducted a three-week field study in waiting rooms of three primary care centers in Groningen. Three versions of a brochure on doctor-patient communication were randomly distributed, 2250 in total. One version contained six short photo stories, another version was non-narrative but contained comparable photos, and the third version was a traditional brochure. Each day we counted how many brochures were taken. We also asked patients (N = 471) to participate in a brief interview. Patients who consented (N = 390) were asked if they had noticed the brochure. If yes (N = 135), they were asked why they had or had not browsed the brochure, and why they had or had not taken it. Interview responses were categorized by two authors. Only 2.9% of the brochures were taken; no significant association with brochure version was found. Analysis of the interview data showed that the version with the photo narrative was noticed significantly more often than the non-narrative version or the traditional version. These results suggest that designing attractive and comprehensible health materials is not enough. Healthcare organizations should also create effective strategies to reach their target population

The proportion of postmenopausal breast cancer cases in the Netherlands attributable to lifestyle-related risk factors

We aimed to estimate the proportion of Dutch postmenopausal breast cancer cases in 2010 that is attributable to lifestyle-related risk factors. We calculated population attributable fractions (PAFs) of potentially modifiable risk factors for postmenopausal breast cancer in Dutch women aged >50 in 2010. First, age-specific PAFs were calculated for each risk factor, based on their relative risks for postmenopausal breast cancer (from meta-analyses) and age-specific prevalence in the population (from national surveys) around the year 2000, assuming a latency period of 10 years. To obtain the overall PAF, age-specific PAFs were summed in a weighted manner, using the age-specific breast cancer incidence rates (2010) as weights. 95 % confidence intervals for PAF estimates were derived by Monte Carlo simulations. Of Dutch women >40 years, in 2000, 51 % were overweight/obese, 55 % physically inactive (<5 days/week 30 min activity), 75 % regularly consumed alcohol, 42 % ever smoked cigarettes and 79 % had a low-fibre intake (<3.4 g/1000 kJ/day). These factors combined had a PAF of 25.7 % (95 % CI 24.2–27.2), corresponding to 2,665 Dutch postmenopausal breast cancer cases in 2010. PAFs were 8.8 % (95 % CI 6.3–11.3) for overweight/obesity, 6.6 % (95 % CI 5.2–8.0) for alcohol consumption, 5.5 % (95 % CI 4.0–7.0) for physical inactivity, 4.6 % (95 % CI 3.3–6.0) for smoking and 3.2 % (95 % CI 1.6–4.8) for low-fibre intake. Our findings imply that modifiable risk factors are jointly responsible for approximately one out of four Dutch postmenopausal breast cancer cases. This suggests that incidence rates can be lowered substantially by living a more healthy lifestyle
