Shared decision-making in multiple sclerosis physical symptomatic care: a systematic review.

Background: Multiple sclerosis (MS) is a chronic autoimmune inflammatory, demyelinating, and neurodegenerative disease affecting young adults. People with MS are highly interested in engaging in physical symptom management and decision-making but are often not actively engaged in symptom management discussions. Research examining the benefit of shared decision-making in the management of physical MS symptoms is sparse. Objectives: This study aimed to identify and synthesize the evidence on the use of shared decision-making in physical MS symptom management. Design: This study is a systematic review of published evidence on the use of shared decision-making in physical MS symptom management. Data sources and methods: MEDLINE, CINAHL, EMBASE, and CENTRAL databases were searched in April 2021, June 2022, and April 2, 2023, for primary, peer-reviewed studies of shared decision-making in the management of MS physical symptoms. Citations were screened, data extracted, and study quality assessed according to Cochrane guidelines for systematic reviews, including risk of bias assessment. Statistical synthesis of the included study results was not appropriate; results were summarized in a nonstatistical manner using the vote-counting method to estimate beneficial versus harmful effects. Results: Of 679 citations, 15 studies met the inclusion criteria. Six studies addressed shared decision-making in the management of pain, spasms, neurogenic bladder, fatigue, gait disorder, and/or balance issues, and nine studies addressed physical symptoms in general. One study was a randomized controlled trial; most studies were observational studies. All study results and study author conclusions indicated that shared decision-making is important to the effective management of physical MS symptoms. No study results suggested that shared decision-making was harmful or delayed the management of physical MS symptoms. Conclusion: Reported results consistently indicate that shared decision-making is important in effective MS symptomatic care. Further rigorous randomized controlled trials are warranted to investigate the effectiveness of shared decision-making associated with MS physical symptomatic care.

Shared decision-making among people with Multiple Sclerosis (MS) and their healthcare providers in the management of the physical symptoms of MS. Shared decision-making is suggested to be a key mechanism in promoting optimal symptomatic care related to Multiple Sclerosis (MS). Shared decision-making is mostly done and studied in relation to choosing therapies that may slow disease progression but not usually for symptomatic care. There are a few studies highlighting the effect of utilizing shared decision-making in symptomatic care of MS. We performed this study to identify all the published data about using shared decision-making in symptomatic care in MS to answer the research question: What is the evidence on shared decision-making in managing physical MS symptoms? We performed a systematic search for all the related published study results in four large literature databases. We found 15 studies on the use of shared decision-making in the management of MS-related symptoms. We synthesized the study results relating to the use of shared decision-making in symptomatic care of MS. The studies used several different designs and included a wide range of study rigor and quality. The results of our systematic review are: All the studies were consistent in their conclusions that shared decision-making is important for effective MS-related symptom management.Several studies found that symptomatic care is of the highest priority to people with MS, but not often a priority to their health care providers.The use of a shared decision-making model can promote discussion of symptoms in clinical consultations and align the goals of people with MS and their health care providers.Education of people with MS regarding their symptoms and available treatments will promote effective shared decision-making discussions. The available evidence supports that the use of shared decision-making is beneficial to the management of physical symptoms of MS. Further studies using a randomized controlled study design are required to establish the degree of benefit of utilizing shared decision-making associated with MS symptomatic care.

Sigma-2 Receptors-From Basic Biology to Therapeutic Target: A Focus on Age-Related Degenerative Diseases.

There is a large unmet medical need to develop disease-modifying treatment options for individuals with age-related degenerative diseases of the central nervous system. The sigma-2 receptor (S2R), encoded by TMEM97, is expressed in brain and retinal cells, and regulates cell functions via its co-receptor progesterone receptor membrane component 1 (PGRMC1), and through other protein-protein interactions. Studies describing functions of S2R involve the manipulation of expression or pharmacological modulation using exogenous small-molecule ligands. These studies demonstrate that S2R modulates key pathways involved in age-related diseases including autophagy, trafficking, oxidative stress, and amyloid-ß and α-synuclein toxicity. Furthermore, S2R modulation can ameliorate functional deficits in cell-based and animal models of disease. This review summarizes the current evidence-based understanding of S2R biology and function, and its potential as a therapeutic target for age-related degenerative diseases of the central nervous system, including Alzheimer's disease, α-synucleinopathies, and dry age-related macular degeneration.

Long-Term Outcomes of ADHD: Academic Achievement and Performance.

Objective: The aim of this study was to synthesize published data regarding long-term effects of ADHD on information learned (measured via achievement tests) and success within the school environment (academic performance). Method: A systematic search identified 176 studies (1980-2012) of long-term (≥2 years) academic outcomes with ADHD. Results: Achievement test outcomes (79%) and academic performance outcomes (75%) were worse in individuals with untreated ADHD compared with non-ADHD controls, also when IQ difference was controlled (72% and 81%, respectively). Improvement in both outcome groups was associated with treatment, more often for achievement test scores (79%) than academic performance (42%), also when IQ was controlled (100% and 57%, respectively). More achievement test and academic performance outcomes improved with multimodal (100% and 67%, respectively) than pharmacological (75% and 33%) or non-pharmacological (75% and 50%) treatment alone. Conclusion: ADHD adversely affects long-term academic outcomes. A greater proportion of achievement test outcomes improved with treatment compared with academic performance. Both improved most consistently with multimodal treatment.

Nociceptive transient receptor potential canonical 7 (TRPC7) mediates aging-associated tumorigenesis induced by ultraviolet B.

Aging, cancer, and longevity have been linked to intracellular Ca2+ signaling and nociceptive transient receptor potential (TRP) channels. We found that TRP canonical 7 (TRPC7) is a nociceptive mechanoreceptor and that TRPC7 channels specifically mediate the initiation of ultraviolet B (UVB)-induced skin aging and tumor development due to p53 gene family mutations. Within 30 min after UVB irradiation, TRPC7 mediated UVB-induced Ca2+ influx and the subsequent production of reactive oxygen species in skin cells. Notably, this function was unique to TRPC7 and was not observed for other TRP channels. In TRPC7 knockout mice, we did not observe the significant UVB-associated pathology seen in wild-type mice, including epidermal thickening, abnormal keratinocyte differentiation, and DNA damage response activation. TRPC7 knockout mice also had significantly fewer UVB-induced cancerous tumors than did wild-type mice, and UVB-induced p53 gene family mutations were prevented in TRPC7 knockout mice. These results indicate that TRPC7 activity is pivotal in the initiation of UVB-induced skin aging and tumorigenesis and that the reduction in TRPC7 activity suppresses the UVB-induced aging process and tumor development. Our findings support that TRPC7 is a potential tumor initiator gene and that it causes cell aging and genomic instability, followed by a change in the activity of proto-oncogenes and tumor suppressor genes to promote tumorigenesis.

Antimicrobial susceptibility testing (AST) and associated clinical outcomes in individuals with cystic fibrosis: A systematic review.

BACKGROUND: Antimicrobial susceptibility testing (AST) is a cornerstone of infection management. Cystic fibrosis (CF) treatment guidelines recommend AST to select antimicrobial treatments for CF airway infection but its utility in this setting has never been objectively demonstrated. METHODS: We conducted a systematic review of primary published articles designed to address two PICO (patient, intervention, comparator, outcome) questions: 1) "For individuals with CF, is clinical response to antimicrobial treatment of bacterial airways infection predictable from AST results available at treatment initiation?" and 2) "For individuals with CF, is clinical response to antimicrobial treatment of bacterial airways infection affected by the method used to guide antimicrobial selection?" Relationships between AST results and clinical response (changes in pulmonary function, weight, signs and symptoms of respiratory tract infection, and time to next event) were assessed for each article and results were compared across articles when possible. RESULTS: Twenty-five articles describing the results of 20 separate studies, most of which described Pseudomonas aeruginosa treatment, were identified. Thirteen studies described pulmonary exacerbation (PEx) treatment and seven described 'maintenance' of chronic bacterial airways infection. In only three of 16 studies addressing PICO question #1 was there a suggestion that baseline bacterial isolate antimicrobial susceptibility was associated with clinical response to treatment. None of the four studies addressing PICO question #2 suggested that antimicrobial selection methods influenced clinical outcomes. CONCLUSIONS: There is little evidence that AST predicts the clinical outcome of CF antimicrobial treatment, suggesting a need for careful consideration of current AST use by the CF community.

Cystic fibrosis in young children: A review of disease manifestation, progression, and response to early treatment.

BACKGROUND: Studies have described illness associated with cystic fibrosis (CF) early in life, but there is no comprehensive accounting of the prevalence and ages of disease manifestation and progression described in individual studies. METHODS: We searched for peer-reviewed English-language studies of the health of children ≤6years old with CF (published 1990-2014). Structural abnormalities and dysfunction of the digestive and respiratory systems were summarized across relevant studies by system and age group. RESULTS: Primary studies (125 total) from 22 countries described abnormalities, dysfunction, and disease progression in infancy and early childhood. Improved health was consistently observed in association with diagnosis via newborn screening compared with cohorts diagnosed later by symptomatic presentation. CONCLUSIONS: The peer-reviewed literature is remarkably consistent: CF-associated growth impairment and airway abnormalities are reported at birth, and disease progression is reported in infancy and throughout childhood. Earlier access to routine CF management is associated with improved subsequent health status.

Effect of Treatment Modality on Long-Term Outcomes in Attention-Deficit/Hyperactivity Disorder: A Systematic Review.

Effect of treatment modality on long-term outcomes in attention-deficit/hyperactivity disorder: a systematic review.

BACKGROUND: Evaluation of treatments for attention-deficit/hyperactivity disorder (ADHD) previously focused on symptom control, but attention has shifted to functional outcomes. The effect of different ADHD treatment periods and modalities (pharmacological, non-pharmacological, and combination) on long-term outcomes needs to be more comprehensively understood. METHODS: A systematic search of 12 literature databases using Cochrane's guidelines yielded 403 English-language peer-reviewed, primary studies reporting long-term outcomes (≥2 years). We evaluated relative effects of treatment modalities and durations and effect sizes of outcomes reported as statistically significantly improved with treatment. RESULTS: The highest proportion of improved outcomes was reported with combination treatment (83% of outcomes). Among significantly improved outcomes, the largest effect sizes were found for combination treatment. The greatest improvements were associated with academic, self-esteem, or social function outcomes. A majority of outcomes improved regardless of age of treatment initiation (60%-75%) or treatment duration (62%-72%). Studies with short treatment duration had shorter follow-up times (mean 3.2 years total study length) than those with longer treatment durations (mean 7.1 years total study length). Studies with follow-up times <3 years reported benefit with treatment for 93% of outcomes, whereas those with follow-up times ≥3 years reported treatment benefit for 57% of outcomes. Post-hoc analysis indicated that this result was related to the measurement of outcomes at longer periods (3.2 versus 0.4 years) after treatment cessation in studies with longer total study length. CONCLUSIONS: While the majority of long-term outcomes of ADHD improve with all treatment modalities, the combination of pharmacological and non-pharmacological treatment was most consistently associated with improved long-term outcomes and large effect sizes. Older treatment initiation age or longer durations did not markedly affect proportion of improved outcomes reported, but measurement of outcomes long periods after treatment cessation may attenuate results.

Economic impact of childhood/adolescent ADHD in a European setting: the Netherlands as a reference case.

Attention-deficit/hyperactivity disorder (ADHD) is a highly prevalent psychiatric disorder in children/adolescents. This study reviews available European-based studies of ADHD-related costs and applies the findings to the Netherlands to estimate annual national costs for children/adolescents from a societal perspective. A systematic literature search was conducted for primary studies in Europe, published January 1, 1990 through April 23, 2013. Per-person cost estimates were converted to 2012 Euros and used to estimate annual national ADHD-related costs based on the Dutch 2011 census, ADHD prevalence rates, family composition, and employment rates. Seven studies met the inclusion criteria. The average total ADHD-related costs ranged from €9,860 to 14,483 per patient and annual national costs were between €1,041 and €1,529 million (M). The largest cost category was education (€648 M), representing 62 and 42 % of the low- and high-value overall national estimates, respectively. By comparison, ADHD patient healthcare costs ranged between €84 M (8 %) and €377 M (25 %), and social services costs were €4.3 M (0.3-0.4 %). While the majority of the costs were incurred by ADHD patients themselves, €161 M (11-15 %) was healthcare costs to family members that were attributable to having an ADHD child/adolescent. In addition, productivity losses of family members were €143-€339 M (14-22 %). Despite uncertainties because of the small number of studies identified and the wide range in the national cost estimates, our results suggest that ADHD imposes a significant economic burden on multiple public sectors in Europe. The limited number of European-based studies examining the economic burden of ADHD highlights the need for more research in this area.

Economic impact of childhood and adult attention-deficit/hyperactivity disorder in the United States.

OBJECTIVE: Attention-deficit/hyperactivity disorder (ADHD) is one of the most prevalent mental disorders in children in the United States and often persists into adulthood with associated symptomatology and impairments. This article comprehensively reviews studies reporting ADHD-related incremental (excess) costs for children/adolescents and adults and presents estimates of annual national incremental costs of ADHD. METHOD: A systematic search for primary United States-based studies published from January 1, 1990 through June 30, 2011 on costs of children/adolescents and adults with ADHD and their family members was conducted. Only studies in which mean annual incremental costs per individual with ADHD above non-ADHD controls were reported or could be derived were included. Per-person incremental costs were adjusted to 2010 U.S. dollars and converted to annual national incremental costs of ADHD based on 2010 U.S. Census population estimates, ADHD prevalence rates, number of household members, and employment rates by age group. RESULTS: Nineteen studies met the inclusion criteria. Overall national annual incremental costs of ADHD ranged from $143 to $266 billion (B). Most of these costs were incurred by adults ($105 B-$194 B) compared with children/adolescents ($38 B-$72 B). For adults, the largest cost category was productivity and income losses ($87 B-$138 B). For children, the largest cost categories were health care ($21 B-$44 B) and education ($15 B-$25 B). Spillover costs borne by the family members of individuals with ADHD were also substantial ($33 B-$43 B). CONCLUSION: Despite a wide range in the magnitude of the cost estimates, this study indicates that ADHD has a substantial economic impact in the United States. Implications of these findings and future directions for research are discussed.

A systematic review and analysis of long-term outcomes in attention deficit hyperactivity disorder: effects of treatment and non-treatment.

BACKGROUND: In childhood, attention deficit/hyperactivity disorder (ADHD) is characterized by age-inappropriate levels of inattentiveness/disorganization, hyperactivity/impulsiveness, or a combination thereof. Although the criteria for ADHD are well defined, the long-term consequences in adults and children need to be more comprehensively understood and quantified. We conducted a systematic review evaluating the long-term outcomes (defined as 2 years or more) of ADHD with the goal of identifying long-term outcomes and the impact that any treatment (pharmacological, non-pharmacological, or multimodal) has on ADHD long-term outcomes. METHODS: Studies were identified using predefined search criteria and 12 databases. Studies included were peer-reviewed, primary studies of ADHD long-term outcomes published between January 1980 to December 2010. Inclusion was agreed on by two independent researchers on review of abstracts or full text. Published statistical comparison of outcome results were summarized as poorer than, similar to, or improved versus comparators, and quantified as percentage comparisons of these categories. RESULTS: Outcomes from 351 studies were grouped into 9 major categories: academic, antisocial behavior, driving, non-medicinal drug use/addictive behavior, obesity, occupation, services use, self-esteem, and social function outcomes. The following broad trends emerged: (1) without treatment, people with ADHD had poorer long-term outcomes in all categories compared with people without ADHD, and (2) treatment for ADHD improved long-term outcomes compared with untreated ADHD, although not usually to normal levels. Only English-language papers were searched and databases may have omitted relevant studies. CONCLUSIONS: This systematic review provides a synthesis of studies of ADHD long-term outcomes. Current treatments may reduce the negative impact that untreated ADHD has on life functioning, but does not usually 'normalize' the recipients.

A systematic review of global publication trends regarding long-term outcomes of ADHD.

There is increased global recognition of attention deficit hyperactivity disorder (ADHD) as a serious medical condition with long-term consequences. Although originally conceived of as a childhood disorder, ADHD is being increasingly recognized in adults. Individual geographic regions may have specific interests and objectives for the study of ADHD. A systematic review of long-term outcomes (LTOs) in ADHD was conducted to evaluate research on ADHD LTOs on a global scale. Studies that were at least 2 years in duration were examined. A total of 351 studies were identified in the final analysis. We identified nine outcomes of interest and classified studies by specific geographical regions, age groups studied and study design by region and over time. Published studies of LTOs in ADHD have increased in all geographical regions over the past three decades, with a peak number of 42 publications in 2008. This rise in publications on ADHD LTOs may reflect a rise in global interest and recognition of consequences and impairment associated with ADHD. Although many world regions have published on ADHD LTOs, the majority of studies have emerged from the US and Canada, followed by Europe. While investigators in the US and Canada were predominantly interested in drug addiction as a LTO, European researchers were more interested in antisocial behavior, and Eastern Asian investigators focused on both of these LTOs as well as self-esteem. Geographical differences in the focus of ADHD LTO studies may reflect regional variations in cultural values. Proportionally fewer prospective longitudinal studies and proportionally more retrospective and cross-sectional studies have been published in more recent decades. Finally, more studies focusing on ADHD in adolescents and adults have been conducted in recent years, and particularly adolescents in Eastern Asia. These changes in basic study design may reflect an increase in the recognition that ADHD is a lifetime chronic disorder. This systematic review analysis of publication trends in ADHD LTOs reflects geographically based interests that change over time.

Vitamin B6 therapy during childbearing years: cause for caution?

Vitamin B6, or pyridoxine, is either prescribed or recommended in large doses for a variety of ailments. These ailments include morning sickness and premenstrual syndrome, despite the fact that the effect of large doses of vitamin B6 on developing human fetuses is currently unknown. Both clinical reports and recent experimental evidence indicate, however, that large doses of vitamin B6 can have adverse affects on proprioceptive neuron function, and these deficits may be permanent if caused during development. This evidence suggests that ingestion of large quantities of vitamin B6 should be viewed with caution by pregnant women and women of childbearing potential.
