Journal of Neurology, Neurosurgery, and... Nov 2023The literature on predictors of persistent postural-perceptual dizziness (PPPD) following peripheral vestibular insults has not been systematically reviewed.
BACKGROUND
The literature on predictors of persistent postural-perceptual dizziness (PPPD) following peripheral vestibular insults has not been systematically reviewed.
METHODS
We systematically reviewed studies on predictors of PPPD and its four predecessors (phobic postural vertigo, space-motion discomfort, chronic subjective dizziness and visual vertigo). Investigations focused on new onset chronic dizziness following peripheral vestibular insults, with a minimum follow-up of 3 months. Precipitating events, promoting factors, initial symptoms, physical and psychological comorbidities and results of vestibular testing and neuroimaging were extracted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines.
RESULTS
We identified 13 studies examining predictors of PPPD or PPPD-like chronic dizziness. Anxiety following vestibular injury, dependent personality traits, autonomic arousal and increased body vigilance following precipitating events and visual dependence, but not the severity of initial or subsequent structural vestibular deficits or compensation status, were the most important predictors of chronic dizziness. Disease-related abnormalities of the otolithic organs and semi-circular canals and age-related brain changes seem to be important only in a minority of patients. Data on pre-existing anxiety were mixed.
CONCLUSIONS
After acute vestibular events, psychological and behavioural responses and brain maladaptation are the most likely predictors of PPPD, rather than the severity of changes on vestibular testing. Age-related brain changes appear to have a smaller role and require further study. Premorbid psychiatric comorbidities, other than dependent personality traits, are not relevant for the development of PPPD.

Review
OBJECTIVE
The purpose of this systematic review was to describe the occurrence of sleep disruptions in pediatric cancer patients and to identify and discuss the factors related to the hospital sleep environment that may be associated with disturbed sleep.
METHODS
A total of 108 articles were located in five databases (PubMed, PsychINFO, Medline, CancerLit, and Google Scholar), and seven met our inclusion criteria and formed the basis of this review.
RESULTS
Participants ranged from 1 to 18 years (n = 147). Data from objective and subjective assessments of sleep showed that child sleep was disrupted in the hospital when compared to previously established age-related norms. Noise, light levels, and staff room interruptions were associated with decreased total sleep minutes and increased nighttime awakenings. Methodological limitations of the current research as well as potential directions for future research are discussed.
CONCLUSIONS
Investigations into the sources of increased sleep difficulties can be used to inform hospital procedures to create a more supportive sleep environment and more effective screening tools for patients who may be at greater risk for sleep difficulties. This may help to minimize the role that hospitalization plays in precipitating and perpetuating chronic sleep disturbances in pediatric cancer patients. Copyright © 2016 John Wiley & Sons, Ltd.

Tumour necrosis factor-α (TNF-α) inhibitors are increasingly being used as immunomodulators to manage inflammatory conditions such as rheumatoid arthritis and Crohn's disease. Reported serious side effects include an increased incidence of lymphoma and greater susceptibility to infections such as tuberculosis. The aim of this systematic review was to find out whether there is an associated risk of medication-related osteonecrosis of the jaw (MRONJ). Three authors independently searched PubMed, MEDLINE, EMBASE, CINAHL and the Cochrane Central Register of Controlled Trials for published reports of oral osteonecrosis (ONJ) or osteomyelitis (OM) in patients who took anti TNF-α drugs and had no history of antiangiogenic agents or antiresorptive treatment. All types of studies on humans treated with TNF-α inhibitors were considered. Only six were eligible for analysis, and all were independently assessed for risk of bias. They included six patients with ONJ or OM that was attributed solely to TNF-α inhibitors. The most common site of ONJ was the posterior mandible (n=5). The mean (SD) duration of anti-TNF-α treatment before the development of bony lesions was 62.5 (47.4) months. Invasive surgery was reported as a precipitating factor in five cases, and the ONJ/OM resolved with conservative management in five. Although all the studies were judged to be at high risk of bias, the limited data suggest that some patients will potentially develop ONJ/OM as a result of treatment with TNF-α inhibitors. Studies of higher quality are now needed to establish the relative risk of MRONJ in patients who take them.

Review
BACKGROUND
Sleep disorders are very common in migrants and refugees, often as a comorbid disorder to different somatic or psychiatric diagnoses and psychological disturbances such as metabolic syndrome, post-traumatic stress disorder, depression, and anxiety disorders.
OBJECTIVES
To review published prevalence rates as well as possible predictors for sleep disturbances in these vulnerable groups, including pre-migration stress, acculturation, and trauma before, during, and after migration, integration, and lifestyle in the host country with implications for predictive, preventive, and personalized medical approach (3PM).
DATA SOURCES
Electronic databases PubMed, PsycInfo, and Web of Knowledge were searched using (combined) search terms "migrant," "asylum seeker," "refugee," "sleep disturbances," "sleep disorder," "insomnia," and "sleep wake disorder."
STUDY ELIGIBILITY CRITERIA
Peer-reviewed studies from 2000 to 2018 reporting data on prevalence and/or predictors of any measure of sleep disturbance were included.
PARTICIPANTS
Studies on international migrants and refugees, as well as internally displaced populations, were included.
METHODS
We conducted a systematic review on the topic of sleep disorders in migrant and refugee populations. Only published articles and reviews in peer-reviewed journals were included.
RESULTS
We analyzed five studies on sleep disorders in migrants, five studies on adult refugees, and three on refugee children and adolescents. Prevalence of sleep disorders in migrants and refugees ranges between 39 and 99%. In migrant workers, stress related to integration and adaptation to the host society is connected to higher risks of snoring, metabolic diseases, and insomnia. Sleep disturbances in refugees are predicted by past war experience. Sleep difficulties in adult and child refugees are strongly correlated to trauma. Torture of parents and grandparents can predict sleep disorders in refugee children, while being accompanied by parents to the host country has a protective effect on children's sleep.
CONCLUSIONS AND IMPLICATIONS
Considering the differences in risk factors, vulnerability, and traumatic life events for different migrant populations, origins of sleep difficulties vary, depending on the migrant populations. Effects on sleep disturbances and sleep quality may be a result of integration in the host country, including changes of lifestyle, such as diet and working hours with implication for OSAS (obstructive sleep apnea) and insomnia. Compared with migrant populations, sleep disturbances in refugee populations are more correlated with mental health symptoms and disorders, especially PTSD (post-traumatic stress disorder), than with psychosocial problems. In juvenile refugee populations, psychological problems and disturbed sleep are associated with traumatic experiences during their journey to the host country. Findings highlight the need for expert recommendations for development of 3P approach stratified in the following: (1) prediction, including structured exploration of predisposing and precipitating factors that may trigger acute insomnia, screening of the according sleep disorders by validated translated questionnaires and sleep diaries, and a face-to-face or virtual setting and screening of OSAS; (2) target prevention by sleep health education for female and male refugees and migrant workers, including shift workers; and (3) personalized medical approach, including translated cognitive behavioral treatment for insomnia (CBT-I) and imagery rehearsal therapy for refugees and telehealth programs for improved CPAP adherence in migrants, with the goal to enable better sleep health quality and improved health economy.

Review
BACKGROUND
Recent years have seen marked improvements in end-of-life care, however concerns have been expressed that services are focused on the needs of patients with cancer. This review focuses on conversations about end-of-life care with frail and older people who have no main overriding diagnosis who are estimated to account for around 40% of deaths.
AIM
To investigate the attitudes of the public and healthcare professionals to advance care planning discussions with frail and older people.
DESIGN AND SETTING
Systematic literature review and narrative synthesis.
METHOD
Articles that related to frail or older individuals and either advance care plans or discussions on end-of-life care were included. Studies of specific conditions or that focused on prognosis, capacity, or resuscitation decisions were excluded.
RESULTS
While a significant minority of frail older individuals would find them unwelcome, the majority would appreciate the chance to discuss end-of-life care, yet most do not have this opportunity. Attitudes to the timing of these discussions were variable, but most perceived the risk of leaving them too late. Most doctors believed it was their professional responsibility to initiate discussions, but felt limited by time pressures and the absence of a precipitating event. A wide range of barriers were identified including the reluctance of family members to discuss end-of-life care, the passive expectation that someone else would decide on an individual's behalf, and significant uncertainty concerning future illness and decline.
CONCLUSION
The marked disparity between the majority of older individuals who would like the opportunity to discuss their end-of-life care and the minority that currently have this opportunity raises important questions if the wishes of this large group in society are to be respected. The challenge is to find effective ways of encouraging dialogue and choice within the constraints of the current healthcare systems and personal circumstances.

Review
OBJECTIVE
May-Thurner syndrome (MTS) is increasingly recognized as a frequent source of leg swelling and a precipitating factor for venous thromboembolism. This paper is a systematic review of the English literature on MTS with an analysis focusing on gender differences in presentation and treatment.
METHODS
A systematic review of the English literature between April 1967 and December 2014 was performed using the following terms: "May-Thurner syndrome," "Cockett syndrome," and "iliac vein compression syndrome." After review, there were 174 articles in the analysis. We first analyzed all presented cases, followed by a gender comparison if case reports and case series had detailed description. Asymptomatic patients with just anatomic compression without symptoms were excluded. Statistical differences between data sets were assessed using χ test and Student t-test.
RESULTS
There were 1569 patients with MTS after exclusion of articles based on our criteria. The female to male ratio was 2:1 (976 [67.1%] vs 480 [32.9%]). Women presented at a younger age compared with men (38.7 ± 14.0 years vs 46.2 ± 16.9 years; P = .02). Gender comparison at presentation, which was available for 254 patients, showed that men had significantly more reported leg swelling (92.7% vs 80.8%; P = .037) and more leg pain (88% vs 74.3%; P = .045) compared with women. There was no difference in the reported proportion of patients presenting with deep venous thrombosis between the two groups (88.9% vs 81.7%; P = .14). However, women were significantly more likely to have a pulmonary embolus on presentation compared with men (9.9% vs 1.6%; P = .035). Treatment modalities included endovascular interventions without thrombolysis (53%) or with thrombolysis (33.2%), open surgery (6.8%), and medical management (7%). Endovascular treatment was more common than surgical or medical treatment (P < .001). Because of lack of granularity in the data, it was not possible to distinguish treatment methods between female and male patients. There was no statistically significant difference in complication rate between men and women based on the articles that provided that information (P = .34). However, open procedures had significantly higher complications compared with endovascular interventions (P = .021).
CONCLUSIONS
Based on the reported literature, MTS is more common in women and is at least twice as frequent in women as in men. Men tend to have more pain and swelling in the legs, whereas women tend to be younger and more likely to have a pulmonary embolus on presentation. MTS and iliac vein compression are sometimes used interchangeably in an inaccurate manner.

Review
OBJECTIVES
Treating the precipitating factors of delirium is the mainstay of the prevention and treatment of delirium. We aim to investigate the role of anemia and blood transfusion within the multicomponent prevention and treatment strategy of delirium.
DESIGN
Systematic review.
SETTING
We included cohort studies or Randomized Controlled Trials (RCTs) that considered blood transfusion as treatment for delirium or risk factor, and had delirium as outcome.
PARTICIPANTS
Hospitalized patients above 55 years old.
MEASUREMENTS
We searched MEDLINE from 1946 through November 2014. Quality assessment and data extraction were performed systematically.
RESULTS
We included 23 studies (n = 29,471). The majority of the studies (n = 22) had a limited quality and for one study quality was uncertain. Two studies evaluated the association between transfusion strategy and postoperative delirium and found no association. Twenty-one studies investigated blood transfusion as a risk factor for delirium. In four of the 21 studies it could be assumed that delirium occurred after transfusion. One of these studies stated that transfusion was a significant risk factor for subsequent delirium (odds ratio (OR) = 3.68, 95% confidence interval (CI) = 1.32-10.94). The other three studies found no association between transfusion and delirium. In the remaining 17 studies, it was not clear whether delirium occurred before or after transfusion, so no conclusion could be drawn on the role of transfusion in delirium development.
CONCLUSION
The majority of the included studies was not suited to answer the research question properly as the time course of the beginning of delirium as to transfusion was lacking. Our review shows that there is no good quality evidence available for blood transfusion to be a risk factor for delirium or to be a preventive or treatment option.

Review
Dietary temptations and lapses challenge control over eating and act as barriers toward successful weight loss. These are difficult to assess in laboratory settings or with retrospective measures as they occur momentarily and driven by the current environment. A better understanding of how these experiences unfold within real-world dieting attempts could help inform strategies to increase the capacity to cope with the changes in appetitive and affective factors that surround these experiences. We performed a narrative synthesis on the empirical evidence of appetitive and affective outcomes measured using ecological momentary assessment (EMA) during dieting in individuals with obesity and their association with dietary temptations and lapses. A search of three databases (Scopus, Medline, and PsycInfo) identified 10 studies. Within-person changes in appetite and affect accompany temptations and lapses and are observable in the moments precipitating a lapse. Lapsing in response to these may be mediated through the strength of a temptation. Negative abstinence-violation effects occur following a lapse, which negatively impact self-attitudes. Engagement in coping strategies during temptations is effective for preventing lapses. These findings indicate that monitoring changes in sensations during dieting could help identify the crucial moments when coping strategies are most effective for aiding with dietary adherence.

Pervasive refusal syndrome (PRS) is a complex condition that affects young people leading to social withdrawal, inability or refusal to eat, drink, mobilise or speak. The affected individual regresses and is unable to self-care and quite characteristically will resist rehabilitation, worsen with praise or remain entirely passive. This systematic review was aimed at describing clinical features of PRS, current interventions and to summarise some of the nosological aspects of the condition. Without language restriction, an electronic search was conducted in Embase, PsychInfo, Medline, Cochrane library, and PubMed databases yielding 29 articles with a total of 79 cases. We performed a risk of assessment bias using an adapted Newcastle-Ottawa Scale and adhered to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. 124 articles were identified, of which 29 were included and these yielded 79 cases. Seventy-six percent of the studies had a low rate of risk of assessment bias (good quality). Our results show that PRS overlaps with several conditions, mainly affects young females aged 7-15 years and has a recovery rate of 78% if diagnosed and treated early but the duration of inpatient treatment may last up to 9.44 months (8.82 SD). The patients had multiple inter-dependent risks. The major predisposing factors included vulnerable premorbid personality and pre-existing mental disorder. Precipitating factors were stressors such as infection and traumatic experiences. Enmeshed parent-child relationship served as a maintaining factor. The themes of treatment approach are essentially rehabilitative: (1) working collaboratively with patient and family, (2) having access to multidisciplinary team, and (3) peer/group supervision. This study has systematically evaluated a large sample of patients with PRS to ascertain its clinical features and the core elements of its treatment. Its key treatment approach is a multi-modal rehabilitative strategy that is compassionate, transparent and inclusive.

Review
Delirium is a sudden and usually transient disturbance in consciousness, attention, cognition, perception and emotions. The pathophysiology is unknown but possible causes include neurotransmitter disturbances and inflammation reaction. Delirium is common in patients after open cardiac surgeries and can lead to serious consequences. Research shows that delirium is an underdiagnosed and undertreated problem. The purpose of this systematic review is to illuminate the prevalence, risk factors and outcome of postoperative delirium following open cardiac surgery. A systematic literature review from 2005-2013 was performed aiming to determine the prevalence, predisposing and precipitating factors and outcome after postoperative delirium following cardiac surgery. Web of Science, PubMed and Cinahl were searched. Findings of the systematic review shows that about one third of patients become delirious after cardiac surgery. Primary predisposing factors are advanced age, cognitive impairment, atrial fibrillation, depression and prior history of stroke. Among precipitating factors are pulmonary bypass, duration of mechanical ventilation, low cardiac output, respiratory failure, pneumonia, infections, blood cell transfusion and post-operative arrhythmias. Delirium causes prolonged hospital stay, reduced activity and higher mortality. Delirium prevention includes reducing risk factors. Delirium is a common and serious complication of open cardiac surgery. Knowledge of risk factors of delirium and regular screening for symptoms of delirium are important to reduce prevalence and to facilitate diagnosis and treatment.
