Review
BACKGROUND AND OBJECTIVE
Pain in patients with Alzheimer's disease is a complex issue; these patients suffer from the common causes of acute and chronic pain, and some also have neuropathic or nociceptive pain. Whatever the mechanism of pain in these patients, their pain will require careful assessment and management, to insure the correct type and level of analgesia is given. The objective of this systematic review was the identification of studies that have investigated the efficacy of different analgesics on pain intensity or pain-related behavior during nursing home stay and at the end of life.
METHODS
A search using pain, pain treatment, and dementia MESH terms and keywords was conducted (October 15, 2015) in MEDLINE, EMBASE, PsychINFO, CINAHL, and Cochrane libraries.
RESULTS
Our search yielded 3138 unique hits, published between 1990 and October 2015. We read titles and abstracts, identified 124 papers for full-text evaluation, and included 12 papers to reflect and synthesize the following questions: (1) Which pain assessment tools for people with dementia are responsive to change in pain intensity scores? (2) Which analgesics are efficacy-tested by controlled trials including people with dementia living in nursing homes, including at the end of life? (3) Which outcome measures have been used to identify pain, pain behavior, and/or treatment efficacy in people with dementia?
CONCLUSION
Despite increased use of analgesics, pain is still prevalent in people with dementia. Validated pain tools are available but not implemented and not fully tested on responsiveness to treatment. Official guidelines for pain assessment and treatment addressing people with dementia living in a nursing home are lacking. The efficacy of analgesic drug use on pain or neuropsychiatric behavior related to dementia has been hardly investigated.

Review
Field walking tests are commonly employed to evaluate exercise capacity, assess prognosis and evaluate treatment response in chronic respiratory diseases. In recent years, there has been a wealth of new literature pertinent to the conduct of the 6-min walk test (6MWT), and a growing evidence base describing the incremental and endurance shuttle walk tests (ISWT and ESWT, respectively). The aim of this document is to describe the standard operating procedures for the 6MWT, ISWT and ESWT, which can be consistently employed by clinicians and researchers. The Technical Standard was developed by a multidisciplinary and international group of clinicians and researchers with expertise in the application of field walking tests. The procedures are underpinned by a concurrent systematic review of literature relevant to measurement properties and test conduct in adults with chronic respiratory disease. Current data confirm that the 6MWT, ISWT and ESWT are valid, reliable and responsive to change with some interventions. However, results are sensitive to small changes in methodology. It is important that two tests are conducted for the 6MWT and ISWT. This Technical Standard for field walking tests reflects current evidence regarding procedures that should be used to achieve robust results.

BMC Gastroenterology Jun 2022There are limited comparative data for infliximab and vedolizumab in inflammatory bowel disease patients. (Meta-Analysis)
Meta-Analysis
BACKGROUND AND AIMS
There are limited comparative data for infliximab and vedolizumab in inflammatory bowel disease patients.
METHODS
We conducted a systematic review and meta-analysis to compare the efficacy and safety of infliximab and vedolizumab in adult patients with moderate-to-severe Crohn's disease or ulcerative colitis.
RESULTS
We identified six eligible Crohn's disease and seven eligible ulcerative colitis trials that randomised over 1900 participants per disease cohort to infliximab or vedolizumab. In the Crohn's disease and ulcerative colitis cohorts, infliximab yielded better efficacy than vedolizumab for all analysed outcomes (CDAI-70, CDAI-100 responses, and clinical remission for Crohn's disease and clinical response and clinical remission for ulcerative colitis) during the induction phase, with non-overlapping 95% confidence intervals. In the maintenance phase, similar proportions of infliximab- or vedolizumab-treated patients achieved clinical response, clinical remission, or mucosal healing in both Crohn's disease and ulcerative colitis. For the safety outcomes, rates of adverse events, serious adverse events, and discontinuations due to adverse events were similar in infliximab- and vedolizumab-treated patients in both diseases. The infection rate was higher in infliximab for Crohn's disease and higher in vedolizumab when treating patients with ulcerative colitis. There was no difference between the treatments in the proportions of patients who reported serious infections in both indications.
CONCLUSIONS
Indirect comparison of infliximab and vedolizumab trials in adult patients with moderate-to severe Crohn's disease or ulcerative colitis demonstrated that infliximab has better efficacy in the induction phase and comparable efficacy during the maintenance phase and overall safety profile compared to vedolizumab.

Meta-Analysis Review
OBJECTIVES
Remitting seronegative symmetrical synovitis with pitting oedema (RS(3)PE) syndrome is a rare inflammatory arthritis, characterised by symmetrical distal synovitis, pitting oedema of the hands and feet, absence of rheumatoid factor, and favourable response to glucocorticoids. The aim of our study is to further delineate the clinical and laboratory features, and response to treatment.
METHODS
We performed a systematic electronic search of Medline, PubMed, EMBASE, ACR and EULAR databases for case reports, case series, and related articles of RS(3)PE. Statistical analysis was done comparing categorical variables with Chi-square tests and frequencies of means via t-tests. Binary logistic regression analysis was performed to identify predictors of erosions, recurrence, malignancy and rheumatologic disorders.
RESULTS
331 cases of RS(3)PE were identified from 121 articles. RS(3)PE was found in older patients (71±10.42 years) predominantly in males (n= 211, 63.36%), was symmetrical (n=297/311, 95.50%) involved the hands (n=294/311, 94.53%) A concurrent rheumatologic condition was reported in 22 cases (6.65%), and malignancy in 54 cases (16.31%). Radiographic joint erosions were found in 5.5%. Most patients responded to medium-dose glucocorticoids (16.12±9.5 mg/day). Patients with concurrent malignancy requiring non-significantly higher doses of prednisone (18.12 vs. 15.76 mg, p 0.304) and higher likelihood of recurrence of disease (OR 4.04, 95% CI 1.10-14.88, p=0.03).
CONCLUSIONS
The symptoms and unique findings that make up RS(3)PE appear to represent a steroid-responsive disease that may be a harbinger of an underlying malignancy. More study is needed to understand the molecular origins of RS(3)PE in order to determine whether it is a separate disease process. Patients with concurrent cancer tend to have more severe presentations and higher rates of recurrence.

Review
BACKGROUND
Rheumatoid arthritis (RA) is an autoimmune disease, symmetrically affecting the small joints. Biomarkers are tools that can be used in the diagnosis and monitoring of RA.
AIM
To systematically explore the role of the biomarkers: C-reactive protein (CRP), rheumatoid factor (RF), anti-cyclic citrullinated protein (Anti-CCP), 14-3-3η protein, and the multi-biomarker disease activity (MBDA) score for the diagnosis and treatment of RA.
METHODS
A systematic review of the English literature using four different databases was carried out.
RESULTS
CRP >7.1 mg/L predicted poor conventional synthetic disease-modifying antirheumatic drugs (csDMARDs) outcome in RA. Anti-CCP, CRP ≥0.3 mg/dL, and RF predicted bone erosion and cartilage destruction. Combination of high 14-3-3η protein with RF and CRP improved the prediction of rapid erosion progression (REP). Anti-CCP was not associated with disease activity but was associated with increased radiographic damage (r = 0.46, p = 0.048). RF was not associated with joint damage but correlated with ultrasound-detected bone erosion. The 14-3-3η protein significantly correlated with inflammation, bone rremodeling, and osteoporosis in RA patients (p < 0.05). In addition, the 14-3-3η protein positively correlated with RA duration (p = 0.003), disease aactivity, and positive RF (p = 0.025) and it distinguished early from established RA. Early MBDA scores correlated with later response in disease activity after 6 and 12 weeks of treatment (p < 0.05). The MBDA score was able to differentiate between small differences in disease activity, predicted remission over 1-year pperiod, and was a strong predictor of radiographic progression of RA.
CONCLUSION
The investigated biomarkers are helpful tools in clinical practice for diagnosis, monitoring of treatment, and predicting prognosis in RA patients. However, further research is still required to investigate novel biomarkers for the pre-treatment selection of potentially responsive patients before starting therapy for a precision medicine in this area.

Review
The Mini-Balance Evaluation Systems Test (Mini-BESTest) has been identified as the most comprehensive balance measure for community-dwelling adults and elderly individuals. It can be used to assess balance impairments in several other conditions, mainly Parkinson's disease and stroke. Despite increasing use of the Mini-BESTest since it was first published 5 years ago, no systematic review synthesizing its psychometric properties is available. The aim of this study was to provide a comprehensive review of the psychometric properties of the Mini-BESTest when administered to patients with balance deficits because of different diseases. A literature search was performed on articles published before July 2015 in journals indexed by MEDLINE and Scopus databases. The search produced 98 papers, 24 of which fulfilled the inclusion criteria for this review. Most papers (n=19) focused on patients affected by neurological diseases, mainly Parkinson's disease. In 21 papers, the psychometric characteristics were analyzed using Classical Test Theory methods and in only three papers was Rasch analysis carried out. This review shows the interest of researchers in the Mini-BESTest despite the short time frame since its first publication. The Mini-BESTest is used widely in both clinical practice and research. The results support the reliability, validity, and responsiveness of this instrument and it can be considered a standard balance measure. However, it would be valuable to learn more about how this scale performs in different diseases causing balance deficits and to better define the minimal clinically important difference for each disease.

Review
RATIONALE, AIMS, AND OBJECTIVES
The 6-minute walk test (6MWT) is widely used as a test of functional exercise capacity. Several studies have reported the minimal clinically important difference (MCID) for the 6MWT; however, the findings of the studies have not been examined in the context of one another. In this review, we aimed to summarize available information on the MCID for the 6MWT performed by patients with pathology.
METHODS
Relevant literature was identified by searches of 3 electronic databases (PubMed, Scopus, and Cumulative Index of Nursing and Allied Health), examination of article reference lists, and consultation with an expert. Inclusion necessitated that articles (1) be original, full length, and peer reviewed, (2) report an MCID for the 6MWT, and (3) focus on adults with medical issues. Articles were excluded if the MCID was determined by a procedure other than receiver operating characteristic curve analysis. Articles were abstracted for information on participants, interventions, 6MWT distance, and the determination of MCID. Quality was assessed using a hybrid 9-item (0- to 18-point) instrument.
RESULTS
Six articles were selected based on the inclusion and exclusion criteria. The populations studied included people with chronic obstructive pulmonary disease, lung cancer, coronary artery disease, diffuse parenchymal lung disease, and non-cystic fibrosis bronchiectasis and adults with fear of falling. Mean baseline 6MWT distances ranged from 295 to 551 m. The MCIDs for which the area under the receiver operating characteristic curve was at least 0.70 ranged from 14.0 to 30.5 m.
CONCLUSIONS
Based on our findings, a change of 14.0 to 30.5 m may be clinically important across multiple patient groups.

Review
INTRODUCTION
There are increasing reports of COVID-19 related neurological complications which may be due to direct viral invasion, or immune mediated inflammatory diseases such as autoimmune encephalitis and ADEM (acute demyelinating encephalomyelitis). In this study, a systematic review is presented of the reported cases infected by the COVID-19 who were diagnosed with various forms of autoimmune encephalitis (AE).
METHODS
The authors searched three databases including PubMed, Scopus, and Web of science for extracting original articles on coronavirus/ COVID-19 and AE.
RESULTS
Eighteen articles were considered in this study, including 15 case reports, and three case series with a total of 81 patients. Among the studies, 19 cases were reported with AE including 7 (37%) cases of limbic encephalitis, 5 (26%) patients with anti-N-methyl-d-aspartate (NMDA) receptor encephalitis, 2 (11%) with AE presenting as new-onset refractory status epilepticus (NORSE), 1 (5%) case of steroid-responsive encephalitis, and 4 (21%) cases with an unknown type of AE.
CONCLUSION
Our systematic review revealed evidence on AE development in patients infected with the COVID-19. Clinicians should be aware of the possible diagnosis of AE when considering other neurological differential diagnosis in SARS-CoV-2 infected patients.

Review
Cerebral infarction/ischemia-reperfusion injury is currently the disease with the highest mortality and disability rate of cardiovascular disease. Current studies have shown that nerve cells die of ischemia several hours after ischemic stroke, which activates the innate immune response in the brain, promotes the production of neurotoxic substances such as inflammatory cytokines, chemokines, reactive oxygen species and - nitrogen oxide, and mediates the destruction of blood-brain barrier and the occurrence of a series of inflammatory cascade reactions. Meanwhile, the expression of adhesion molecules in cerebral vascular endothelial cells increased, and immune inflammatory cells such as polymorphonuclear neutrophils, lymphocytes and mononuclear macrophages passed through vascular endothelial cells and entered the brain tissue. These cells recognize antigens exposed by the central nervous system in the brain, activate adaptive immune responses, and further mediate secondary neuronal damage, aggravating neurological deficits. In order to reduce the above-mentioned damage, the body induces peripheral immunosuppressive responses through negative feedback, which increases the incidence of post-stroke infection. This process is accompanied by changes in the immune status of the ischemic brain tissue in local and systemic systems. A growing number of studies implicate noncoding RNAs (ncRNAs) as novel epigenetic regulatory elements in the dysfunction of various cell subsets in the neurovascular unit after cerebral infarction/ischemia-reperfusion injury. In particular, recent studies have revealed advances in ncRNA biology that greatly expand the understanding of epigenetic regulation of immune responses and inflammation after cerebral infarction/ischemia-reperfusion injury. Identification of aberrant expression patterns and associated biological effects of ncRNAs in patients revealed their potential as novel biomarkers and therapeutic targets for cerebral infarction/ischemia-reperfusion injury. Therefore, this review systematically presents recent studies on the involvement of ncRNAs in cerebral infarction/ischemia-reperfusion injury and neuroimmune inflammatory cascades, and elucidates the functions and mechanisms of cerebral infarction/ischemia-reperfusion-related ncRNAs, providing new opportunities for the discovery of disease biomarkers and targeted therapy. Furthermore, this review introduces clustered regularly interspaced short palindromic repeats (CRISPR)-Display as a possible transformative tool for studying lncRNAs. In the future, ncRNA is expected to be used as a target for diagnosing cerebral infarction/ischemia-reperfusion injury, judging its prognosis and treatment, thereby significantly improving the prognosis of patients.

BACKGROUND
Type 1 diabetes (T1D) results from immune-mediated destruction of insulin-producing beta cells. Efforts to prevent T1D have focused on modulating immune responses and supporting beta cell health; however, heterogeneity in disease progression and responses to therapies have made these efforts difficult to translate to clinical practice, highlighting the need for precision medicine approaches to T1D prevention.
METHODS
To understand the current state of knowledge regarding precision approaches to T1D prevention, we performed a systematic review of randomized-controlled trials from the past 25 years testing disease-modifying therapies in T1D and/or identifying features linked to treatment response, analyzing bias using a Cochrane-risk-of-bias instrument.
RESULTS
We identified 75 manuscripts, 15 describing 11 prevention trials for individuals with increased risk for T1D, and 60 describing treatments aimed at preventing beta cell loss in individuals at disease onset. Seventeen agents tested, mostly immunotherapies, showed benefit compared to placebo (only two prior to T1D onset). Fifty-seven studies employed precision analyses to assess features linked to treatment response. Age, measures of beta cell function and immune phenotypes were most frequently tested. However, analyses were typically not prespecified, with inconsistent methods reporting, and tended to report positive findings.
CONCLUSIONS
While the quality of prevention and intervention trials was overall high, low quality of precision analyses made it difficult to draw meaningful conclusions that inform clinical practice. Thus, prespecified precision analyses should be incorporated into the design of future studies and reported in full to facilitate precision medicine approaches to T1D prevention.
PLAIN LANGUAGE SUMMARY
Type 1 diabetes (T1D) results from the destruction of insulin-producing cells in the pancreas, necessitating lifelong insulin dependence. T1D prevention remains an elusive goal, largely due to immense variability in disease progression. Agents tested to date in clinical trials work in a subset of individuals, highlighting the need for precision medicine approaches to prevention. We systematically reviewed clinical trials of disease-modifying therapy in T1D. While age, measures of beta cell function, and immune phenotypes were most commonly identified as factors that influenced treatment response, the overall quality of these studies was low. This review reveals an important need to proactively design clinical trials with well-defined analyses to ensure that results can be interpreted and applied to clinical practice.
