Review
BACKGROUND
Colorectal cancer (CRC) metastasis commonly occurs in the liver and lungs with bone metastasis rarely occurring in isolation. Disseminated carcinomatosis of bone marrow (DCBM) is extremely rare in CRC. We conducted a systematic review to provide more information on the diagnosis, treatment options, and prognosis of the condition.
METHODS
Studies were identified by performing searches on MEDLINE and EMBASE electronic databases according to the PRISMA statement standards. We included a single patient whom we treated for metastatic CRC presenting with DCBM in our study. Statistical analysis was performed using SPSS software version 23.0.
RESULTS
A search through 5502 unique studies yielded 14 studies that were eventually included. There was a total of 17 cases of DCBM in CRC with back pain and constitutional symptoms as the most common presenting complaints. DCBM in CRC was associated with markedly elevated CEA of 275.57 (95% CI 17.13-534.00). There was no predilection for site of primary tumour. Overall median survival was 120 days (95% CI 64.43-175.58). The median survival for patients who received chemotherapy was 240 days (95% CI 71.11-408.89), as compared to 9 days (95% CI 1.80-16.20) for patients who received best supportive treatment.
CONCLUSION
DCBM from CRC is extremely rare. Bone marrow examination remains the gold standard for diagnosis. Colonic stenting or surgical diversion may be more appropriate than primary resection in obstructed CRC in view of the poor prognosis. Systemic chemotherapy shows promise in increasing median survival.

Review
BACKGROUND AND OBJECTIVE
The Cochrane Drugs and Alcohol Group aims to produce, update, and disseminate systematic reviews on the prevention, treatment, and rehabilitation of problematic drug and alcohol use. This paper describes what the Group has done since the 1990s to produce evidence to guide policy, practice, and research.
METHOD
We analyze the coverage of topics by our reviews, the body of studies they have included, and the evidence produced.
RESULTS
By July 2013, the Group had published 67 reviews, with 376 authors from 25 different countries. These reviews included 906 studies, of 3061 studies considered for inclusion. Most (90%) included studies were randomized trials. Considering the 'Implications for practice' section of each review, 41% interventions were classified as 'do it', 15% as 'do not do', and 44% as 'do only in research'. These proportions varied according to the type of substance of abuse studied. The proportion of 'do it' interventions were 46% for alcohol, 40% for opioids, 20% for psychostimulants, 40% for polydrugs, and 62% for prevention.
CONCLUSION
Cochrane Reviews produced by the Drugs and Alcohol Group provide evidence on the effectiveness of several interventions, and identify areas of uncertainty where new research is needed.

Review
BACKGROUND
The need to better understand implementing evidence-informed dementia care has been recognised in multiple priority-setting partnerships. The aim of this scoping review was to give an overview of the state of the evidence on implementation and dissemination of dementia care, and create a systematic evidence map.
METHODS
We sought studies that addressed dissemination and implementation strategies or described barriers and facilitators to implementation across dementia stages and care settings. Twelve databases were searched from inception to October 2015 followed by forward citation and grey literature searches. Quantitative studies with a comparative research design and qualitative studies with recognised methods of data collection were included. Titles, abstracts and full texts were screened independently by two reviewers with discrepancies resolved by a third where necessary. Data extraction was performed by one reviewer and checked by a second. Strategies were mapped according to the ERIC compilation.
RESULTS
Eighty-eight studies were included (30 quantitative, 34 qualitative and 24 mixed-methods studies). Approximately 60% of studies reported implementation strategies to improve practice: training and education of professionals (94%), promotion of stakeholder interrelationships (69%) and evaluative strategies (46%) were common; financial strategies were rare (15%). Nearly 70% of studies reported barriers or facilitators of care practices primarily within residential care settings. Organisational factors, including time constraints and increased workload, were recurrent barriers, whereas leadership and managerial support were often reported to promote implementation. Less is known about implementation activities in primary care and hospital settings, or the views and experiences of people with dementia and their family caregivers.
CONCLUSION
This scoping review and mapping of the evidence reveals a paucity of robust evidence to inform the successful dissemination and implementation of evidence-based dementia care. Further exploration of the most appropriate methods to evaluate and report initiatives to bring about change and of the effectiveness of implementation strategies is necessary if we are to make changes in practice that improve dementia care.

Meta-Analysis Review
BACKGROUND
Dematiaceous fungi cause a number of infectious syndromes referred to as phaeohyphomycosis among both immunocompetent and immunocompromised hosts. We performed a systematic review to characterize these infections in solid organ transplant recipients (SOTR).
METHODS
We searched PubMed database (last searched 1/6/2022) for English-language reports on dematiaceous fungal infections in SOTR. Included reports needed individualized demographic, treatment, and outcome data; pediatric reports were excluded. A universally applicable bias assessment was performed on reports. Models for infection type and outcome were created using the Bayesian paradigm.
RESULTS
We included 149 reports on 201 cases of dematiaceous fungal infections in SOTR. The mean age was 54 years, 72% were men, and kidney recipients accounted for 61% of cases. Skin and soft tissue infection (SSTI) was the most common infectious syndrome (73%). Death from infection occurred in 7% of cases (14/201), with disseminated (32%) cases having the highest mortality. Our model for infection type predicted the relative probability of central nervous system infection to be highest in liver recipients. Across all transplant types, higher relative probabilities of disseminated and pulmonary infections occur in the early post-transplant period, and the predicted probabilities for these infection types decreased after 100 months post-transplantation.
DISCUSSION
We identified SSTI as the most common dematiaceous fungal infections in SOTR. Disseminated infections carried the worst prognosis. The evidence in this review is limited by the heterogeneity of included cases. No funding source was used, and this review's protocol was not registered.

Meta-Analysis
BACKGROUND
Acute disseminated encephalomyelitis (ADEM) is a rare demyelinating disorder that is often misdiagnosed. To improve early diagnosis, we performed a systematic review and meta-analysis of clinical features, outcomes for ADEM in adults.
METHODS
The PubMed, Embase, Web of Science and Cochrane Library databases were searched for studies reporting the clinical features of adults with ADEM between January 1990 and May 2021. A random-effects meta-analysis model was used to pool data on clinical features and functional outcomes.
RESULTS
Twelve studies examining 437 adults with ADEM met the inclusion criteria. Overall, the clinical features and diagnostic findings observed in more than two-thirds of the patients were white matter lesions [87.1%, 95% confidence interval (CI)=75-95.6], polyfocal onset (80.5%, 95% CI=50.5-98.9) and pyramidal signs (68.7%, 95% CI =40.0-91.9). The mortality rate was 7.8% (95% CI = 3.3-13.5), and the risk of residual deficits was 47.5% (95% CI = 31.8-63.4).
CONCLUSIONS
Adults with ADEM had worse outcomes than children. Clinicians should maintain high clinical suspicion for patients presenting with certain clinical features and diagnostic findings.

Acute disseminated encephalomyelitis (ADEM) has been reported after coronavirus disease 2019 (COVID-19). In this review, we systematically included worldwide reported cases on this association. We included 30 case reports (pediatric and adults) and explored epidemiological and clinical evidence. We described time to diagnosis, clinical, imaging, and laboratory features, response to treatment regimens, and differences regarding severity. Also, an original case report was presented. Neurologists must be alert to the occurrence of multifocal neurological symptoms with or without encephalopathy in patients recovered from COVID-19. Timely MRI studies should be performed to establish the diagnosis and to consider early corticosteroid-based treatment.

Review
BACKGROUND
Research centers and programs focused on dissemination and implementation science (DIS) training, mentorship, and capacity building have proliferated in recent years. There has yet to be a comprehensive inventory of DIS capacity building program (CBP) cataloging information about activities, infrastructure, and priorities as well as opportunities for shared resources, collaboration, and growth. The purpose of this systematic review is to provide the first inventory of DIS CBPs and describe their key features and offerings.
METHODS
We defined DIS CBPs as organizations or groups with an explicit focus on building practical knowledge and skills to conduct DIS for health promotion. CBPs were included if they had at least one capacity building activity other than educational coursework or training alone. A multi-method strategy was used to identify DIS CBPs. Data about the characteristics of DIS CBPs were abstracted from each program's website. In addition, a survey instrument was developed and fielded to gather in-depth information about the structure, activities, and resources of each CBP.
RESULTS
In total, 165 DIS CBPs met our inclusion criteria and were included in the final CBP inventory. Of these, 68% are affiliated with a United States (US) institution and 32% are internationally based. There was one CBP identified in a low- and middle-income country (LMIC). Of the US-affiliated CBPs, 55% are embedded within a Clinical and Translational Science Award program. Eighty-seven CBPs (53%) responded to a follow-up survey. Of those who completed a survey, the majority used multiple DIS capacity building activities with the most popular being Training and Education (n=69, 79%) followed by Mentorship (n=58, 67%), provision of DIS Resources and Tools (n=57, 66%), Consultation (n=58, 67%), Professional Networking (n=54, 62%), Technical Assistance (n=46, 52%), and Grant Development Support (n=45, 52%).
CONCLUSIONS
To our knowledge, this is the first study to catalog DIS programs and synthesize learnings into a set of priorities and sustainment strategies to support DIS capacity building efforts. There is a need for formal certification, accessible options for learners in LMICs, opportunities for practitioners, and opportunities for mid/later stage researchers. Similarly, harmonized measures of reporting and evaluation would facilitate targeted cross-program comparison and collaboration.

Review
Qualitative methods are progressively being implemented by researchers for exploration within healthcare. However, there has been a longstanding and wide-ranging debate concerning the relative merits of qualitative research within the health care literature. This integrative review aimed to exam the contribution of qualitative research in burns care and subsequent rehabilitation. Studies were identified using an electronic search strategy using the databases PubMed, Cumulative Index of Nursing and Allied Health Literature (CINAHL), Excerpta Medica database (EMBASE) and Scopus of peer reviewed primary research in English between 2009 to April 2014 using Whittemore and Knafl's integrative review method as a guide for analysis. From the 298 papers identified, 26 research papers met the inclusion criteria. Across all studies there was an average of 22 participants involved in each study with a range of 6-53 participants conducted across 12 nations that focussed on burns prevention, paediatric burns, appropriate acquisition and delivery of burns care, pain and psychosocial implications of burns trauma. Careful and rigorous application of qualitative methodologies promotes and enriches the development of burns knowledge. In particular, the key elements in qualitative methodological process and its publication are critical in disseminating credible and methodologically sound qualitative research.

Review
BACKGROUND
Multiple sclerosis is a chronic demyelinating disorder with a myriad of imaging and clinical features that overlap with number of other neurological conditions. Incorrect diagnosis poses a significant risk to patients, it may lead to delays in management, increased morbidity, and also adds to the financial cost.
OBJECTIVE
The aim of this study was to highlight strategies for the efficient differentiation of multiple sclerosis from other diseases which may masquerade as MS clinico-radiologically.
MATERIAL AND METHODS
A systematic literature review was conducted through online databases including PubMed and Medline. Relevant publications on radiological aspects of multiple sclerosis, white matter diseases and mimickers of Multiple sclerosis were included in the analysis.
RESULTS
Common mimickers of MS include small vessel disease, acute disseminated encephalomyelitis, neuromyelitis optica, anti-MOG encephalomyelitis, vasculitis, and CADASIL. Contrast-enhanced MRI study performed using MS protocol on high strength MRI system evaluated following a structured protocol along with clinical correlation is effective in differentiating MS from its mimickers.
CONCLUSIONS
Contrast-enhanced MRI performed on a high strength scanner using MS protocol with structured protocol for evaluation along, with a better collaboration between radiologists and clinicians may help in minimizing errors in diagnosis of multiple sclerosis.

The International Society on Thrombosis and Haemostasis (ISTH) diagnostic criteria for disseminated intravascular coagulation (DIC) are widely used for DIC diagnosis. However, the prognostic value of the score may vary between different patient populations and settings. This systematic review investigated the association between the ISTH DIC score and mortality in sepsis patients. A literature search was conducted in PubMed and Embase. Inclusion criteria were studies including adult and pediatric patients hospitalized with sepsis, using any sepsis definition, and investigating the association between mortality and the ISTH DIC score. The review was conducted according to Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines. In total, 42 studies were included. A positive association between the ISTH DIC score and mortality was consistently reported, with odds ratios of death in DIC versus non-DIC patients ranging from 1.125 (95% confidence interval [CI]: 0.838-1.511) to 21.008 (95% CI: 1.408-313.405) in adults and from 1.378 (95% CI: 1.004-1.893) to 2.99 (95% CI: 0.54-16.6) in pediatric populations. However, the DIC score only had a low-moderate positive predictive value for mortality, as area under receiver-operator characteristics ranged from 0.602 (95% CI: 0.575-0.630) to 0.815 (95% CI: 0.676-0.954) in adults. Of note, only few studies adjusted for potential confounders such as age, gender, and comorbidity. The ISTH DIC score is consistently associated with sepsis-related mortality but is not a strong positive predictor for mortality. Nevertheless, the score may still have a prognostic value and its use in sepsis is encouraged.
