A qualitative evidence synthesis of patient perspectives on migraine treatment features and outcomes.
This quality evidence synthesis examined patient perspectives on migraine treatment features and outcomes. A literature review was conducted, and 19 studies (21 publications) involving 459 patients were included. Eight themes were identified encompassing features preferred by patients in a migraine treatment process. Themes described include a treatment process that included shared decision-making, a tailored approach, trust in health-care professionals, sharing of knowledge and diversity of treatment options, a holistic approach that does not just address the headache, ease of communication especially for complex treatments, a non-undermining approach, and reciprocity with mutual respect between patient and provider. Seven themes emerged including patients' preferences for nonpharmacologic treatment, high effectiveness, rapidity of action, long-lasting effect, lower cost and more accessibility, self-management/self-delivery option that increases autonomy, and a mixed preference for abortive versus prophylactic treatments. High value treatment outcomes to patients included maintaining or improving function; avoiding side effects, potential for addiction to medications, and pain reoccurrence; and avoiding non-headache symptoms such as nausea, vomiting, and sensitivity to light or sounds.

Pharmacologic and dietary treatments for epilepsies in children aged 1-36 months: a systematic review.
The purpose of this systematic review study was to assess the effectiveness and harms of pharmacologic and dietary treatments for epilepsy in children aged 1-36 months without infantile spasms. The researchers searched EMBASE, MEDLINE, PubMed, and the Cochrane Library for studies published from 1/1/1999 to 8/19/21 to identify studies reporting data on children aged 1-36 months receiving pharmacologic or dietary treatments for epilepsy. Twenty-three studies met the inclusion criteria. The study found that Levetiracetam leads to seizure freedom in some infants but the data on 6 other medications (lamotrigine, phenytoin, rufinamide, stiripentol, topiramate, and vigabatrin) were too limited to allow conclusions about their effectiveness. Three medications (lamotrigine, levetiracetam, and topiramate) were rarely discontinued due to adverse effects, and severe events were also rare. In the category of diets, the ketogenic diet lead to seizure freedom in some infants and both the ketogenic diet and modified Atkins diet reduced average seizure frequency.

Prospectively assessed neurodevelopmental outcomes in studies of anaesthetic neurotoxicity in children: a systematic review and meta-analysis.
This systematic review and meta-analysis tried to answer the question whether exposure to a single general anesthetic (GA) in early childhood causes long-term neurodevelopmental problems. Databases searched from inception to October 2019 were PubMed/MEDLINE, Embase, CINAHL, Web of Science, and the Cochrane Library. Outcomes common to at least three studies were evaluated using a random-effects meta-analyses. A total of 841 out of 1644 children who had a single exposure to GA were evaluated. Findings were that there were statistically significant increases in parent reports of behavioral problems but no difference in general intelligence.

Sleep disturbances after pediatric traumatic brain injury: a systematic review of prevalence, risk factors, and association with recovery.
This is a systematic review to quantify sleep wake disturbances (SWD) after pediatric traumatic brain injury (TBI). These SWD can place children at risk for worse outcomes since sleep is needed for brain development and healing after injury. They also evaluated interventions for SWD and the association between SWD and other post-traumatic outcomes. Literature was searched from 1999-2019 evaluating sleep or fatigue in children hospitalized for TBI. Two independent reviewers assessed quality of the studies using the Newcastle-Ottowa Score for observational studies. Out of 966 identified articles, 126 full text articles were reviewed and 24 studies were included. Studies showed at least 20% of children with TBI had some degree of SWD including trouble falling or staying asleep, fatigue, daytime fatigue, and nightmares. SWD was negatively correlated with cognitive, behavioral, and quality of life outcomes. There was moderate-high risk of bias for all studies due to small sample size and lack of validated or objective SWD measures.

Accuracy of biomarker testing for neuropathologically defined Alzheimer disease in older adults with dementia
This study is a systematic review of biomarker and test accuracy for identification of Alzheimer Disease (AD) in older adults. Studies with low or medium risk of bias were analyzed, and two reviewers rated risk of bias. Fifteen brain imaging studies and 9 cerebrospinal fluid (CSF) studies met analysis criteria and were included. The meta-analysis found that in methodologically heterogeneous studies of uncertain applicability to typical clinical settings, the biomarkers amyloid PET, 18F-FDG proton emission tomography (PET), and magnetic resonance imaging (MRI) were highly sensitive for neuropathologic AD. Single studies suggested that adding amyloid PET, 18F-FDG PET, and CSF test combinations may add accuracy to clinical evaluation.

Benefits and harms of prescription drugs and supplements for treatment of clinical Alzheimer-type dementia
This is a systematic review and meta-analysis of the benefits and harms of prescription drugs and supplements for treatment of clinical Alzheimer-type dementia (CATD). Studies with low or medium risk of bias (ROB) were analyzed and rated. The analysis concluded there was a slight reduction in short-term cognitive decline with cholinesterase inhibitors and memantime, and cholinesterase inhibitors slightly reduced reported functional decline. There was mostly insufficient evidence on drug treatment of behavioral and psychological symptoms of dementia and on supplements for all outcomes.

Brief cognitive tests for distinguishing clinical Alzheimer-type dementia from mild cognitive impairment or normal cognition in older adults with suspected cognitive impairment.
Researchers summarized evidence on accuracy and harms of brief cognitive tests for clinical Alzheimer-type dementia (CATD) in older adults with suspected cognitive impairment. They encountered the following limitations: small studies, few test metrics being evaluated by multiple studies, and few studies directly comparing different tests, scores, cut points, or test combinations. They concluded that many brief, single cognitive tests accurately distinguish CATD from normal cognition in older adults but are less accurate in distinguishing mild CATD from normal cognition or CATD from mild cognitive impairment.

Screening for cognitive impairment in older adults: updated evidence report and systematic review for the US Preventive Services Task Force.
The purpose of this study was to systematically review the test accuracy of cognitive screening instruments and benefits and harms of interventions to treat cognitive impairment in older adults (>/=65 years) to inform the US Preventive Services Task Force. The investigators concluded that screening instruments could adequately detect cognitive impairment. They indicated that there was no empirical evidence, however, that screening for cognitive impairment improved patient or caregiver outcomes or causes harm.

Antipsychotics for preventing delirium in hospitalized adults: a systematic review.
The purpose of this study was to conduct a systematic review evaluating the benefits and harms of antipsychotics to treat delirium in adults. Results showed that there was little evidence demonstrating neurologic harms associated with short-term use of antipsychotics for treating delirium in adult inpatients, but potentially harmful cardiac effects tended to occur more frequently. Current evidence does not support routine use of haloperidol or second-generation antipsychotics to treat delirium in adult inpatients.

Patient stakeholder versus physician preferences regarding amyloid PET testing.
Patient and caregiver perspectives on amyloid positron emission tomography (PET) use are largely unexplored, particularly as compared with clinician views. In this study, the investigators surveyed clinicians, patients, caregivers, and dementia advocates on topics relating to an evidence-based guideline on amyloid PET use. They found that patients and caregivers emphasized the importance of having a dementia diagnosis and placed more value on testing and outcomes for asymptomatic populations than clinicians.

Developing the disorders of consciousness guideline and challenges of integrating shared decision-making into clinical practice.
The purpose of this study was to review methodology informing evidence-based guideline development and integration of guidelines into clinical care through shared decision-making (SDM) and to highlight challenges to SDM in disorders of consciousness. Recently published disorders of consciousness guideline recommendations provide strategies for clinicians to enhance quality care for these individuals and also to provide details helping clinicians partner with individuals with disorders of consciousness and their surrogates. Further research is recommended into many aspects of caring for individuals with disorders of consciousness and optimal strategies for partnering with surrogates in decision-making.

A needs assessment of family physicians to inform development of educational resources on antipsychotic use in dementia.
The authors assessed the needs and preferred resources of Iowa physicians to inform the development of educational resources for best practice dementia care and compared the responses of nursing home medical directors with nonmedical directors. They found that medical directors and nonmedical directors had similar preferences for resources used and information needs, with preference for online resources, pocket guides, a handbook, consulting pharmacists, and facility in-services being the most commonly preferred sources of new information. Medical directors were significantly more aware of the FDA warning on antipsychotic use in dementia and treated more nursing home patients. No differences were observed between groups related to confidence in and use of nondrug strategies instead of antipsychotics to manage behavioral symptoms of dementia.

Does cognitive training prevent cognitive decline?: A systematic review.
This review summarized evidence on the effects of cognitive training on cognitive performance and incident dementia outcomes for adults with normal cognition or mild cognitive impairment (MCI). It concluded that results for populations with MCI suggested no effect of training on performance (low-strength and insufficient evidence). Evidence for prevention of cognitive decline or dementia was insufficient.
