Effects of Food and Liquid Properties on Swallowing Physiology and Function in Adults.

Foods and liquids have properties that are often modified as part of clinical dysphagia management to promote safe and efficient swallowing. However, recent studies have questioned whether this practice is supported by the evidence. To address this, a scoping review was conducted to answer the question: "Can properties of food and liquids modify swallowing physiology and function in adults?" Online search in six databases yielded a set of 4235 non-duplicate articles. Using COVIDENCE software, two independent reviewers screened the articles by title and abstract, and 229 full-text articles were selected for full-text review. One-hundred eleven studies met the inclusion criteria for qualitative synthesis and assessment of risk of bias. Three randomized controlled trials and 108 non-randomized studies were analyzed. Large amounts of variability in instrumental assessment, properties of food and liquids, and swallowing measures were found across studies. Sour, sweet, and salty taste, odor, carbonation, capsaicin, viscosity, hardness, adhesiveness, and cohesiveness were reported to modify the oral and pharyngeal phase of swallowing in both healthy participants and patients with dysphagia. Main swallow measures modified by properties of food and liquids were penetration/aspiration, oral transit time, lingual pressures, submental muscle contraction, oral and pharyngeal residue, hyoid and laryngeal movement, pharyngeal and upper esophageal sphincter pressures, and total swallow duration. The evidence pooled in this review supports the clinical practice of food texture and liquid consistency modification in the management of dysphagia with the caveat that all clinical endeavors must be undertaken with a clear rationale and patient-specific evidence that modifying food or liquid benefits swallow safety and efficiency while maintaining quality of life.

Breast Cancer Outcomes of Neoadjuvant Versus Adjuvant Chemotherapy by Receptor Subtype: A Scoping Review.

BACKGROUND: Trials demonstrate equivalent survival for breast cancers treated with neoadjuvant chemotherapy (NAC) or adjuvant chemotherapy (AC). However, these were conducted before the recognition of the importance of receptor subtype for survival and chemotherapy response. Therefore, chemotherapy timing may impact survival for certain receptor subtypes. A scoping review of studies assessing outcomes by chemotherapy timing based on receptor subtype was conducted to evaluate gaps in the existing literature. METHODS: Three databases were searched in February 2019 with terms related to breast cancer, NAC/AC, and survival. Inclusion criteria were original peer-reviewed studies published in English after 1989 comparing breast cancer outcomes for females based on chemotherapy timing. Studies/sections of studies lacking outcomes by receptor subtype or including patients missing appropriate targeted therapy were excluded. RESULTS: Of 7354 articles, 262 abstracts and 60 full texts were reviewed. Three studies met criteria. All were single-institution retrospective studies analyzing outcomes for triple negative (TN) patients with one study also examining luminal A patients. Significant differences in clinical characteristics existed between patients selected for NAC versus AC. Two studies demonstrated no survival difference by chemotherapy timing for TN patients, with the third showing improved likelihood of survival after AC for TN patients. No difference was seen for patients with luminal A cancer. CONCLUSIONS: Our scoping review reveals a significant gap in the existing literature regarding optimal timing of chemotherapy for modern-era patients receiving targeted therapy based on receptor subtype. Review of the identified studies identified methodological challenges to answering this question through observational study designs.

Post-traumatic stress disorder (PTSD) and other trauma-related mental disorders in elite athletes: a narrative review.

This narrative review examines post-traumatic stress disorder (PTSD) and other trauma-related disorders-mental health conditions with complex diagnosis and treatment considerations-in elite athletes. Athletes may exhibit greater rates of PTSD (up to 13%-25% in some athlete populations) and other trauma-related disorders relative to the general population. We describe common inciting events leading to symptoms of PTSD in elite athletes, including trauma incurred in sports participation through direct physical injury, secondary/witnessed traumatic events, or abusive dynamics within sports teams. Symptoms of PTSD may significantly impact athletes' psychosocial and sport-related function through avoidance, hypervigilance and dissociative behaviours, which, in turn, may delay recovery from musculoskeletal injury.While PTSD may be common among elite athletes, recognition by providers who do not routinely screen for trauma-related disorders may be challenging because of the tendency of athletes to mask symptoms of PTSD and other trauma-related disorders. Early identification of athletes suffering from trauma-related symptoms, including those of acute stress disorder, may prevent progression to PTSD, while treatment of athletes already meeting criteria for PTSD may improve life functioning and sports performance outcomes. Current evidence supports increasing awareness of PTSD in athletes and use of screening tools to identify athletes who may benefit from trauma-informed medical or psychotherapeutic interventions.

Problem gambling and associated mental health concerns in elite athletes: a narrative review.

Opportunities to participate in gambling have dramatically changed during the past 20 years. Casinos have proliferated as have electronic gambling machines, lotteries, sports betting, and most recently online gambling. Gambling among the general population has moved from being perceived negatively to a socially acceptable pastime. As over 80% of individuals have reported gambling for money during their lifetime, governments recognise that regulating gambling-a multibillion dollar industry-is a significant source of revenue. While the vast majority of individuals engaged in some form of gambling have no or few gambling-related problems, an identifiable proportion of both adolescents and adults experience significant gambling-related problems. Elite athletes have not been immune to the lure of gambling nor its concomitant problems. Prevalence studies suggest higher rates of gambling problems among athletes than the general population. In this narrative review, we examine several risk factors associated with gambling problems among elite athletes and new forms of gambling that may be problematic for this population. Given the potential serious mental health and performance consequences associated with a gambling disorder for athletes, we aim to increase coaches', athletic directors' and health professionals' knowledge concerning the importance of screening and treatment referrals.

Attention-deficit/hyperactivity disorder in elite athletes: a narrative review.

Attention-deficit/hyperactivity disorder (ADHD) is a common brain developmental disorder in the general population that may be even more prevalent in elite athletes in certain sports. General population studies of ADHD are extensive and have reported on prevalence, symptoms, therapeutic and adverse effects of treatment and new clinical and research findings. However, few studies have reported on prevalence, symptoms and treatments of ADHD in elite athletes. This narrative review summarises the literature on symptoms, comorbidities, effects of ADHD on performance and management options for elite athletes with ADHD. The prevalence of ADHD in student athletes and elite athletes may be 7%-8%. The symptoms and characteristics of ADHD play a role in athletes' choice of a sport career and further achieving elite status. Proper management of ADHD in elite athletes is important for safety and performance, and options include pharmacologic and psychosocial treatments.

Psychotherapy for mental health symptoms and disorders in elite athletes: a narrative review.

BACKGROUND: Athletes, like non-athletes, suffer from mental health symptoms and disorders that affect their lives and their performance. Psychotherapy, either as the sole treatment or combined with other non-pharmacological and pharmacological strategies, is a pivotal component of management of mental health symptoms and disorders in elite athletes. Psychotherapy takes the form of individual, couples/family or group therapy and should address athlete-specific issues while being embraced as normative by athletes and their core stakeholders. MAIN FINDINGS: This narrative review summarises controlled and non-controlled research on psychotherapy for elite athletes with mental health symptoms and disorders. In summary, treatment is similar to that of non-athletes-although with attention to issues that are athlete-specific. Challenges associated with psychotherapy with elite athletes are discussed, including diagnostic issues, deterrents to help-seeking and expectations about services. We describe certain personality characteristics sometimes associated with elite athletes, including narcissism and aggression, which could make psychotherapy with this population more challenging. The literature regarding psychotherapeutic interventions in elite athletes is sparse and largely anecdotal.

Recreational and ergogenic substance use and substance use disorders in elite athletes: a narrative review.

BACKGROUND: Substances from various classes may be used for recreational purposes, self-treatment or to boost performance. When substance use shifts from occasional to regular, heavy or hazardous use, positive and negative effects can develop that vary by substance class and athlete. Regular use of recreational or performance enhancing substances can lead to misuse, sanctions or use disorders. OBJECTIVE: To review the prevalence, patterns of use, risk factors, performance effects and types of intervention for all classes of recreational and performance enhancing substances in elite athletes by sport, ethnicity, country and gender. METHODS: A comprehensive search was conducted to identify studies that compared the prevalence and patterns of substance use, misuse and use disorders in elite athletes with those of non-athletes and provided detailed demographic and sport variations in reasons for use, risk factors and performance effects for each main substance class. RESULTS: Alcohol, cannabis, tobacco (nicotine) and prescribed opioids and stimulants are the most commonly used substances in elite athletes, but generally used at lower rates than in non-athletes. In contrast, use/misuse rates for binge alcohol, oral tobacco, non-prescription opioids and anabolic-androgenic steroids are higher among athletes than non-athletes, especially in power and collision sports. Cannabis/cannabinoids seem to have replaced nicotine as the second most commonly used substance. CONCLUSIONS: Substance use in elite athletes varies by country, ethnicity, gender, sport and competitive level. There are no studies on substance use disorder prevalence in elite male and female athletes and few studies with direct comparison groups.

Bipolar and psychotic disorders in elite athletes: a narrative review.

Bipolar and psychotic disorders are relatively common and likely to have a significant impact on quality of life and functioning which, in the context of elite sport, includes a potential negative impact on sporting performance. For this narrative review article, the literature on bipolar and psychotic disorders in elite athletes was comprehensively searched, and little empirical research was found. A diagnosis of bipolar or psychotic disorders may be challenging in elite athletes because of complicating factors related to the modifying role of exercise and potential precipitating impact of substance use. Medications used to treat bipolar and psychotic disorders may have side effects particularly problematic for elite athletes. Future research should be tailored to the specific characteristics and needs of elite athletes and to the sporting context in which the disorders may arise. Specifically, further research is needed on the prevalence and incidence of these conditions in elite athletes and the impact of both the disorders and their treatments on sporting performance.

Management of mental health emergencies in elite athletes: a narrative review.

Mental health emergencies require a rapid, effective response. We searched the literature on mental health emergencies in athletes and found five papers. None of these addressed elite athletes. Nonetheless, common mental health emergencies may present in the sports environment and may place the athlete and others at risk. Sports teams and organisations should anticipate which emergencies are likely and how medical and support staff can best respond. Responses should be based on general non-sporting guidelines. We stress the importance of clinicians following standard procedures.

Mental health symptoms and disorders in elite athletes: a systematic review on cultural influencers and barriers to athletes seeking treatment.

OBJECTIVE: To summarise the literature on the barriers to athletes seeking mental health treatment and cultural influencers of mental health in elite athletes. DESIGN: Systematic review DATA SOURCES: PubMed, Cochrane, Scopus, SportDiscus (Ebsco), and PsycINFO (ProQuest) up to November 2018. ELIGIBILITY CRITERIA FOR SELECTING STUDIES: Qualitative and quantitative original studies of elite athletes (those who competed at the professional, Olympic, or collegiate/university levels), published in any language. RESULTS: Stigma, low mental health literacy, negative past experiences with mental health treatment-seeking, busy schedules, and hypermasculinity are barriers to elite athletes seeking mental health treatment. Cultural influencers of mental health in elite athletes include: (1) the lack of acceptance of women as athletes; (2) lower acceptability of mental health symptoms and disorders among non-white athletes; (3) non-disclosure of religious beliefs; and (4) higher dependence on economic benefits. Coaches have an important role in supporting elite athletes in obtaining treatment for mental illness. Brief anti-stigma interventions in elite athletes decrease stigma and improve literary about mental health. CONCLUSION: There is a need for various actors to provide more effective strategies to overcome the stigma that surrounds mental illness, increase mental health literacy in the athlete/coach community, and address athlete-specific barriers to seeking treatment for mental illness. In this systematic review, we identified strategies that, if implemented, can overcome the cultural factors that may otherwise limit athletes seeking treatment. Coaches are critical for promoting a culture within elite athletes' environments that encourages athletes to seek treatment.

Occurrence of mental health symptoms and disorders in current and former elite athletes: a systematic review and meta-analysis.

OBJECTIVES: To present an overview of the existing epidemiological evidence regarding the occurrence of mental health symptoms and disorders among current and former elite athletes. DESIGN: Systematic review and meta-analysis. DATA SOURCES: Five electronic databases were searched from inception to November 2018: PubMed (MEDLINE), SportDiscus via EBSCO, PSycINFO via ProQuest, Scopus and Cochrane. ELIGIBILITY CRITERIA FOR SELECTING STUDIES: We included original quantitative studies that were written in English, were conducted exclusively among current or former elite athletes, and presented incidence or prevalence rates of symptoms of mental disorders. RESULTS: Twenty-two relevant original studies about mental health symptoms and disorders among current elite athletes were included: they presented data especially on symptoms of distress, sleep disturbance, anxiety/depression and alcohol misuse. Meta-analyses comprising 2895 to 5555 current elite athletes showed that the prevalence of mental health symptoms and disorders ranged from 19% for alcohol misuse to 34% for anxiety/depression. Fifteen relevant original studies about mental health symptoms and disorders among former elite athletes were included: they similarly presented data especially about symptoms of distress, sleep disturbance, anxiety/depression and alcohol misuse. Meta-analyses comprising 1579 to 1686 former elite athletes showed that the prevalence of mental health symptoms and disorders ranged from 16% for distress to 26% for anxiety/depression. CONCLUSIONS: Our meta-analyses showed that the prevalence of mental health symptoms and disorders ranged from 19% for alcohol misuse to 34% for anxiety/depression for current elite athletes, and from 16% for distress to 26% for anxiety/depression for former elite athletes.

Determinants of anxiety in elite athletes: a systematic review and meta-analysis.

OBJECTIVE: To identify and quantify determinants of anxiety symptoms and disorders experienced by elite athletes. DESIGN: Systematic review and meta-analysis. DATA SOURCES: Five online databases (PubMed, SportDiscus, PsycINFO, Scopus and Cochrane) were searched up to November 2018 to identify eligible citations. ELIGIBILITY CRITERIA FOR SELECTING STUDIES: Articles were included if they were published in English, were quantitative studies and measured a symptom-level anxiety outcome in competing or retired athletes at the professional (including professional youth), Olympic or collegiate/university levels. RESULTS AND SUMMARY: We screened 1163 articles; 61 studies were included in the systematic review and 27 of them were suitable for meta-analysis. Overall risk of bias for included studies was low. Athletes and non-athletes had no differences in anxiety profiles (d=-0.11, p=0.28). Pooled effect sizes, demonstrating moderate effects, were identified for (1) career dissatisfaction (d=0.45; higher anxiety in dissatisfied athletes), (2) gender (d=0.38; higher anxiety in female athletes), (3) age (d=-0.34; higher anxiety for younger athletes) and (4) musculoskeletal injury (d=0.31; higher anxiety for injured athletes). A small pooled effect was found for recent adverse life events (d=0.26)-higher anxiety in athletes who had experienced one or more recent adverse life events. CONCLUSION: Determinants of anxiety in elite populations broadly reflect those experienced by the general population. Clinicians should be aware of these general and athlete-specific determinants of anxiety among elite athletes.

Key Elements of Mammography Shared Decision-Making: a Scoping Review of the Literature.

BACKGROUND: New guidelines recommend shared decision-making (SDM) for women and their clinician in consideration of breast cancer screening, particularly for women ages 35-50 where guidelines for routine mammography are controversial. A number of models offer general guidelines for SDM across clinical practice, yet they do not offer specific guidance about conducting SDM in mammography. We conducted a scoping review of the literature to identify the key elements of breast cancer screening SDM and synthesize these key elements for utilization by primary care clinicians. METHODS: The Cochrane Database of Systematic Reviews; Cumulative Index to Nursing and Allied Health Literature (CINAHL Plus); PsycInfo, PubMed (MEDLINE), Scopus, and SocIndex databases were searched. Inclusion criteria were original studies from peer-reviewed publications (from 2009 or later) reporting breast cancer screening (mammography), medical decision-making, and patient-centered care. Study populations needed to include female patients 18+ years of age facing a real-life breast cancer screening decision. Article findings were specific to shared decision-making and/or use of a decision aid. Data extracted includes study design, population, setting, intervention, and critical findings related to breast cancer screening SDM elements. Scoping analysis includes descriptive analysis of study features and content analysis to identify the SDM key elements. RESULTS: Twenty-four articles were retained. Three thematic categories of key elements emerged from the extracted elements: information delivery/patient education (specific content and delivery modes), interpersonal clinician-patient communication (aspects of interpersonal relationship impacting SDM), and framework of the decision (sociocultural factors beyond direct SDM deliberation). A number of specific breast cancer screening SDM elements relevant to primary care clinical practice are delineated. DISCUSSION: The findings underscore the importance of the relationship between the patient and clinician and the necessity of spelling out each step in the SDM process. The clinician needs to be explicit in telling a woman that she has a choice about whether to get a mammogram and the benefits and harms of screening mammography. Finally, clinicians need to be aware of sociocultural factors that can influence their relationships and their patients' decision-making processes and attempt to identify and address these factors.

Stigma Related Avoidance in People Living with Severe Mental Illness (SMI): Findings of an Integrative Review.

The purpose of this integrative review is to synthesize primary evidence of the impact of internalized stigma on avoidance in adult community treatment patients living with SMI. A keyword database search of articles published through 2015 yielded 21 papers and a total of 4256 patients. Our analyses found that stigmatizing beliefs associated with avoidance are related to significant loss of self-esteem. Factors generally thought to reduce stigma internalized as self-stigmatizing beliefs, such as improved insight, increased self-awareness, and psycho-education to improve stigma coping skills, do not appear to improve self-esteem.

Nodular regenerative hyperplasia and liver transplantation: a systematic review.

Nodular regenerative hyperplasia (NRH) is a primary disease of the liver that may cause noncirrhotic portal hypertension. Common causes include autoimmune, hematologic, immune deficiency, and myeloproliferative disorders. Given the limited data regarding the development of NRH in contemporary immunosuppressive protocols and the occurrence of NRH post-liver transplantation, we systematically reviewed NRH as it pertains to liver transplantation. We performed a comprehensive search for NRH and transplantation. Nineteen studies were identified with relevant data for NRH as an indication for a liver transplant. Thirteen studies were identified with relevant data pertaining to NRH development after liver transplant. Pooled analysis revealed 0.9% of liver transplant recipients had NRH. A total of 113 patients identified with NRH underwent liver transplantation. Most series report transplants done after the failure of endoscopic banding and TIPS management of portal hypertension. Reported 5-year graft and patient survival ranged from 73%-78% and 73%-90%. The pooled incidence of NRH after liver transplant for all indications was 2.9% and caused complications of portal hypertension. Complications related to portal hypertension secondary to NRH are a rare indication for a liver transplant. NRH can develop at any time after liver transplantation often without an identifiable cause, which may lead to portal hypertension requiring treatment or even re-transplantation.

Liver Transplantation for Hepatocellular Carcinoma With Bile Duct Tumor-Associated Thrombi: A Systematic Review and Pooled Analysis.

Introduction: The significance of bile duct tumor-associated thrombi in patients undergoing transplantation for hepatocellular carcinoma (HCC) is controversial. Therefore, we performed a systematic review of the literature with pooled analysis to investigate the impact of biliary invasion on HCC recurrence and patient survival. Methods: Of 1,584 references screened, eight were included for analysis. Demographics, patient and tumor factors, recurrence, and survival data were analyzed. Time to recurrence and death were extracted from each paper by cross-referencing survival curves. Results: A total of 35 patients across eight studies were pooled for analysis when follow-up data were available. At 1 year, 92.9% of patients undergoing transplantation for HCC with bile duct thrombi were alive. Overall survival at 3 and 5 years was 65.5 and 49.6%, respectively. At 1 year, 21.6% of patients had recurrence of their disease, while at 3 years, 50.4% of patients had recurrence. Of those patients with recurrence in the first year, 71.4% recurred within the first 3 months after transplantation. Conclusion: Overall patient survival decreased within the first 5 years, but then stabilized. The 5-year survival rate of 49.6% in this pooled analysis is lower than that reported for patients undergoing transplantation for HCC within the Milan criteria (50-78%) or recent reports in patients with portal vein involvement (63.6%), though data is limited by a lack of long-term follow-up in this understudied population. Transplantation for patients with HCC with bile duct involvement may be a viable treatment option, warranting further investigation.

Non-pharmacological strategies to obtain usable magnetic resonance images in non-sedated infants: Systematic review and meta-analysis.

BACKGROUND: Although the use of sedation is commonly practiced to keep infants still while receiving magnetic resonance imaging, non-pharmacological strategies are a potential alternative. OBJECTIVES: The purpose of this study was to determine the success rate of obtaining usable magnetic resonance images in infants with the sole use of non-pharmacological strategies. DESIGN: Systematic literature review and meta-analysis SETTING: A search was conducted in PubMed, CINAHL and Cochrane Library. PARTICIPANTS: Human infants from birth to 24 months of age who did not receive any sedation or anesthesia during magnetic resonance imaging METHOD: Articles that reported the success rate of obtaining usable images were included. RESULTS: Of the 521 non-duplicate articles found, 58 articles were included in the systematic review with sample sizes ranging from 2-457, an average success rate of 87.8%, and an average scan time of 30 min. The most common non-pharmacological technique included feeding and swaddling infants before imaging to encourage infants to sleep during the scan. Meta-analysis performed on 53 articles comprising 3,410 infants found a success rate of 87%, but significant heterogeneity was found (I2 = 98.30%). It was more difficult to obtain usable images solely with non-pharmacological techniques if infants were critically ill or a structural magnetic resonance imaging of the brain was required. CONCLUSION: Non-pharmacological techniques are effective for obtaining usable magnetic resonance imaging scans in most but not all infants. Tweetable abstract: Non-pharmacological techniques are effective for obtaining usable magnetic resonance imaging scans in most infants.

Physical Activity and White Matter Hyperintensities: A Systematic Review of Quantitative Studies.

OBJECTIVE: White matter hyperintensities (WMH) are markers of brain white matter injury seen on magnetic resonance imaging. WMH increase with age and are associated with neuropsychiatric disorders. WMH progression can be slowed by controlling vascular risk factors in individuals with advanced disease. Since physical activity can decrease vascular risk factors, physical activity may slow the progression of WMH in individuals without advanced disease, thereby preventing neuropsychiatric disorders. The purpose of this systematic review was to examine the association between physical activity and WMH in individuals without advanced disease. METHODS: Articles published in English through March 18, 2014 were searched using PubMed, Web of Science, Cochrane Library and EBSCOhost. RESULTS: Six studies found that more physical activity was associated with less WMH, while 6 found no association. Physical activity is associated with less WMH in individuals without advanced disease when studies are longitudinal or take into consideration physical activity across the lifespan, have a younger sample of older adults, measure different types of physical activity beyond leisure or objectively measure fitness via V02max, measure WMH manually or semi-automatically, and control for risk factors associated with WMH. CONCLUSION: More physical activity was associated with less white matter hyperintensities in individuals without advanced disease.
