Rehabilitation Techniques for Adults Undergoing External Fixation Treatment for Lower Limb Reconstruction: A Systematic Review.

Introduction: External fixation devices are commonly used in orthopaedic surgery to manage a range of pathologies. In this patient population, there is currently no consensus on optimal rehabilitation techniques. There exists a large variation in practice, with a limited understanding of how these affect treatment outcomes. Methods: Following Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines, a systematic review was conducted of Allied and Complementary Medicine Database (AMED), Cumulative Index to Nursing and Allied Health Literature (CINAHL), MEDLINE, PEDro, and COCHRANE databases, grey literature sources and forward and backward searching of included articles. Studies were selected following rigorous screening with predefined inclusion criteria. Data quality was assessed using validated appraisal tools. Articles were synthesised by rehabilitation type and descriptive analysis was subsequently performed. Results: From 1,156 articles identified, 18 were eligible for inclusion. The overall quality was low, with clinical commentaries and case studies being the most common study type. Studies were synthesised by rehabilitation type, the most common themes being gait re-education, strengthening, therapy-assisted, active exercises and weight-bearing exercises. Conclusion: There is a lack of high-quality evidence to support meaningful recommendations and guide rehabilitation practices for this patient cohort. Further research for patients being treated in external fixation, especially related to the potential effects of physical rehabilitation on bone healing, return of strength, mobility and independent function is likely to have transferability within wider orthopaedic populations. Clinical significance: This systematic review is unable to provide clinical recommendations due to the poor quality of the available literature. However, it is hoped this paper will provide a foundation for further research to improve rehabilitation for patients being treated with external fixation.

A single center observational study of the incidence, frequency and timing of critical care physiotherapy intervention during the COVID-19 pandemic.

Introduction: The recent COVID-19 pandemic saw many patients admitted to an intensive care setting and requiring mechanical ventilation. The NHS increased their critical care beds which included expanding the amount of staff. Physiotherapists were a key part of this and were required to complete numerous interventions within the COVID critical care setting throughout the pandemic. Our aim was to collect the incidence and frequency of physiotherapy interventions performed during the COVID-19 pandemic in a critical care setting. Method: Data was collected across all critical care beds at the Royal London Hospital for an eight-week period between March- April 2020. We retrospectively collected physiotherapy interventions for example, endotracheal suctioning and functional rehabilitation for every patient in the critical care setting. The Chelsea Critical Care Physical Assessment Tool (CPAx) scores were also obtained for patients on ACCU admission and discharge. Results: A total of 213 patients were included in the sample, 163 COVID-19 positive and 50 COVID-19 negative. Recorded sessions included secretion management (821), weaning (271), rescue therapy (82) and functional rehab (534) across the eight-week period. The mean CPAx score on admission to ACCU for the entire sample was 9/45 points. On discharge that score had improved to 25/45 points. Conclusion: This unique project has enabled us to report on the critical care physiotherapy interventions provided during the COVID 19 pandemic. This interesting data on frequency and timing of interventions may be useful to plan future relocation staffing plans and optimal allocation of care.

The Massachusetts Hepatitis C Testing Cascade, 2014-2016.

OBJECTIVES: To characterize hepatitis C testing in Massachusetts and guide stakeholders in addressing the needs of people living with hepatitis C. METHODS: All persons with a positive laboratory report for anti-hepatitis C virus (HCV) antibody, between 2014 and 2016, were included in the testing cascade. Outcomes were HCV tests received after a positive anti-HCV antibody test: nucleic acid test or genotype test. Logistic regression analyses were performed to determine factors associated with progression through the HCV testing cascade. RESULTS: Among those reported anti-HCV antibody positive, a total of 13 194 (61%) cases had a subsequent RNA-based test, and 79% (10 374/13 194) were confirmed with current, active HCV infection. For confirmed HCV cases, 44% (4557/10 374) had a genotype identified. The median time from an antibody-positive test to a RNA-based test was 29 days (interquartile range [IQR] = 7-151). Differences in moving through the testing cascade were observed by birth cohort and race/ethnicity. CONCLUSIONS: Improved surveillance capture of demographic information is needed to help public health agencies ensure equity in HCV diagnosis and linkage to care.

Identifying and characterizing hepatitis C virus hotspots in Massachusetts: a spatial epidemiological approach.

BACKGROUND: Hepatitis C virus (HCV) infections have increased during the past decade but little is known about geographic clustering patterns. METHODS: We used a unique analytical approach, combining geographic information systems (GIS), spatial epidemiology, and statistical modeling to identify and characterize HCV hotspots, statistically significant clusters of census tracts with elevated HCV counts and rates. We compiled sociodemographic and HCV surveillance data (n = 99,780 cases) for Massachusetts census tracts (n = 1464) from 2002 to 2013. We used a five-step spatial epidemiological approach, calculating incremental spatial autocorrelations and Getis-Ord Gi* statistics to identify clusters. We conducted logistic regression analyses to determine factors associated with the HCV hotspots. RESULTS: We identified nine HCV clusters, with the largest in Boston, New Bedford/Fall River, Worcester, and Springfield (p < 0.05). In multivariable analyses, we found that HCV hotspots were independently and positively associated with the percent of the population that was Hispanic (adjusted odds ratio [AOR]: 1.07; 95% confidence interval [CI]: 1.04, 1.09) and the percent of households receiving food stamps (AOR: 1.83; 95% CI: 1.22, 2.74). HCV hotspots were independently and negatively associated with the percent of the population that were high school graduates or higher (AOR: 0.91; 95% CI: 0.89, 0.93) and the percent of the population in the "other" race/ethnicity category (AOR: 0.88; 95% CI: 0.85, 0.91). CONCLUSION: We identified locations where HCV clusters were a concern, and where enhanced HCV prevention, treatment, and care can help combat the HCV epidemic in Massachusetts. GIS, spatial epidemiological and statistical analyses provided a rigorous approach to identify hotspot clusters of disease, which can inform public health policy and intervention targeting. Further studies that incorporate spatiotemporal cluster analyses, Bayesian spatial and geostatistical models, spatially weighted regression analyses, and assessment of associations between HCV clustering and the built environment are needed to expand upon our combined spatial epidemiological and statistical methods.

Underascertainment of acute hepatitis C virus infections in the U.S. surveillance system: a case series and chart review.

BACKGROUND: In 2010, the incidence of hepatitis C virus (HCV) infection in the United States was estimated to be 17 000 cases annually, based on 850 acute HCV cases reported to the Centers for Disease Control and Prevention by local public health authorities. Absence of symptomatic disease and lack of a specific laboratory test for acute infection complicates diagnosis and surveillance. OBJECTIVE: To validate estimates of the incidence of acute HCV infection by determining the reporting rate of clinical diagnoses of acute infection to the Massachusetts Department of Public Health (MDPH) and Centers for Disease Control and Prevention. DESIGN: Case series and chart review. SETTING: Two hospitals and the state correctional health care system in Massachusetts. PATIENTS: 183 patients clinically diagnosed with acute HCV infection from 2001 to 2011 and participating in a research study. MEASUREMENTS: Rate of electronic case reporting of acute HCV infection to the MDPH and rate of subsequent confirmation according to national case definitions. RESULTS: 149 of 183 (81.4%) clinical cases of acute HCV infection were reported to the MDPH for surveillance classification. The MDPH investigated 43 of these reports as potential acute cases of HCV infection based on their surveillance requirements; ultimately, only 1 met the national case definition and was counted in nationwide statistics published by the Centers for Disease Control and Prevention. Discordance in clinical and surveillance classification was often related to missing clinical or laboratory data at the MDPH as well as restrictive definitions, including requirements for negative hepatitis A and B laboratory results. LIMITATION: Findings may not apply to other jurisdictions because of differences in resources for surveillance. CONCLUSION: Clinical diagnoses of acute HCV infection were grossly underascertained by formal surveillance reporting. Incomplete clinician reporting, problematic case definitions, limitations of diagnostic testing, and imperfect data capture remain major limitations to accurate case ascertainment despite automated electronic laboratory reporting. These findings may have implications for national estimates of the incidence of HCV infection. PRIMARY FUNDING SOURCE: National Institutes of Health.

Debunking the myth: low knowledge levels of HBV infection among Asian American college students.

OBJECTIVE: To examine the hepatitis B virus (HBV)-related knowledge among Asian American college students and to determine whether there are significant differences in the level of HBV knowledge among Asian American subgroups. METHODS: A cross-sectional survey was self-administered to assess a sample of 258 Asian American students' knowledge about HBV at the campus of the research site. RESULTS: Knowledge regarding transmission and consequences of HBV infection was poor. Of a possible knowledge score of 14, the median number of correct answers was eight. There were no significant differences between the subgroups of Asian American college students in total knowledge of HBV infection. CONCLUSION: The findings of this study point to the fact that the lack of knowledge and awareness is not limited to community settings only but also includes higher education environment. This finding brings to the forefront the importance of HBV education for Asian American college students.

Emerging epidemic of hepatitis C virus infections among young nonurban persons who inject drugs in the United States, 2006-2012.

BACKGROUND: Reports of acute hepatitis C in young persons in the United States have increased. We examined data from national surveillance and supplemental case follow-up at selected jurisdictions to describe the US epidemiology of hepatitis C virus (HCV) infection among young persons (aged ≤30 years). METHODS: We examined trends in incidence of acute hepatitis C among young persons reported to the Centers for Disease Control and Prevention (CDC) during 2006-2012 by state, county, and urbanicity. Sociodemographic and behavioral characteristics of HCV-infected young persons newly reported from 2011 to 2012 were analyzed from case interviews and provider follow-up at 6 jurisdictions. RESULTS: From 2006 to 2012, reported incidence of acute hepatitis C increased significantly in young persons-13% annually in nonurban counties (P = .003) vs 5% annually in urban counties (P = .028). Thirty (88%) of 34 reporting states observed higher incidence in 2012 than 2006, most noticeably in nonurban counties east of the Mississippi River. Of 1202 newly reported HCV-infected young persons, 52% were female and 85% were white. In 635 interviews, 75% of respondents reported injection drug use. Of respondents reporting drug use, 75% had abused prescription opioids, with first use on average 2.0 years before heroin. CONCLUSIONS: These data indicate an emerging US epidemic of HCV infection among young nonurban persons of predominantly white race. Reported incidence was higher in 2012 than 2006 in at least 30 states, with largest increases in nonurban counties east of the Mississippi River. Prescription opioid abuse at an early age was commonly reported and should be a focus for medical and public health intervention.

Screening for Hepatitis C as a Prevention Enhancement (SHAPE) for HIV: an integration pilot initiative in a Massachusetts County correctional facility.

OBJECTIVES: The Massachusetts Department of Public Health (MDPH) and the Barnstable County Sheriff's Department (BCSD) in Massachusetts initiated a pilot program in July 2009 offering education and hepatitis C virus (HCV) antibody testing to inmates and detainees, concurrent with routine HIV testing. The initiative was implemented to assess the feasibility of integrating HCV screening into an HIV screening program in a correctional setting and the efficacy of linking HCV antibody-positive inmates to clinical care upon release. METHODS: Through the Screening for Hepatitis C as a Prevention Enhancement initiative, HCV and HIV testing were offered to inmates and detainees shortly after admission, and by request at any time during incarceration. In preparation for release, referrals were made to community-based medical providers for HCV follow-up care. Data from BCSD were compared with routine surveillance data received by MDPH. Confirmatory HCV test results received by April 15, 2012, were considered indicators of appropriate post-release clinical care. RESULTS: From July 2009 through December 2011, 22% (n=596) and 25% (n=667) of 2,716 inmates/detainees accepted HCV and HIV testing, respectively. Of those tested for HCV antibody, 20.5% (n=122) were positive. Of those tested for HIV antibody, 0.8% (n=5) were positive. Of the inmates who tested HCV positive at BCSD and had been released, 37.8% were identified as receiving post-release medical care. CONCLUSIONS: We determined that integration of HCV education and screening into correctional facilities is feasible and reveals high rates of HCV infection. Although this model presupposes programmatic infrastructure, elements of the service design and integration could inform a range of correctional programs. Effective linkage to care, while substantial, was not routine based on our analysis, and may require additional resources given its cost and complexity.

Hepatitis B virus infection and immunizations among Asian American college students: infection, exposure, and immunity rates.

OBJECTIVES: To evaluate the prevalence of hepatitis B virus (HBV) infection, exposure, and immunity among Asian American college students as a basis for evaluating HBV screening and vaccination policy. PARTICIPANTS AND METHODS: Self-identified Asian American college students aged 18 years or older were examined. Serological tests of HBV surface antigens, antibodies to HBV core antigens (anti-HBc), and antibodies to HBV surface antigens (anti-HBs) were used to determine HBV infection and immunization prevalence. RESULTS: Among US-born students (n = 66), none was infected with HBV, 68% (n = 45) had immunity from vaccination, and 1 student had evidence of past exposure to HBV. Among foreign-born students (n = 142), 4% (n = 5) had evidence of chronic HBV infection, 62% (n = 88) had immunity from vaccination, and 19% (n = 27) had results indicating past exposure to HBV. Asian American college students showed very little knowledge of HBV vaccination; 43% reported that they had received vaccination, whereas 50% did not know whether they had received it or not. CONCLUSIONS: The prevalence of current and past HBV infection among foreign-born Asian American college students is significantly higher (p < .01), than US-born students. The lack of awareness of their HBV-infected status points out the importance of routine HBV screening of high-risk populations such as Asian students.

An epidemiologic update on hepatitis C infection in persons living with or at risk of HIV infection.

Due to shared routes of transmission, coinfection with both human immunodeficiency virus type 1 (HIV-1) and hepatitis C virus (HCV) is relatively common and results in accelerated liver disease, driving morbidity and mortality. Deaths related to HCV now exceed deaths related to HIV in the United States, and co-infected patients bear a significant proportion of that mortality. This burden may be addressed by novel antiviral therapies that promise increased rates of cure or by enhanced access to liver transplantation, but these are costly interventions. Ultimately, the future burden of coinfection is addressed by greater understanding of who is at risk for development of each infection, thus guiding preventive efforts. Key recent reports regarding the US burden of morbidity and mortality due to HCV and groups at risk for coinfection are reviewed, with a focus on recently described HCV occurring among young injection drug users and men who have sex with men. Given the lack of available vaccine against HCV, enhanced detection and surveillance is a vital component of our public health strategy to combat HCV.

Enhancing surveillance for hepatitis C through public health informatics.

Disease surveillance for hepatitis C in the United States is limited by the occult nature of many of these infections, the large volume of cases, and limited public health resources. Through a series of discrete processes, the Massachusetts Department of Public Health modified its surveillance system in an attempt to improve timeliness and completeness of reporting and case follow-up of hepatitis C. These processes included clinician-based reporting, electronic laboratory reporting, deployment of a Web-based disease surveillance system, automated triage of pertinent data, and automated character recognition software for case-report processing. These changes have resulted in an increase in the timeliness of reporting.

Navigated abdominal T1-W MRI permits free-breathing image acquisition with less motion artifact.

T1-W imaging of the pediatric abdomen is often limited by respiratory motion artifacts. Although navigation has been commonly employed for coronary MRA and T2-W imaging, navigation for T1-W imaging is less developed. Thus, we incorporated a navigator pulse into a fat-suppressed T1-W SPGR sequence such that steady-state contrast was not disrupted. Ten children were scanned after gadolinium administration three times in immediate succession: breath-hold with no navigation, free-breathing with navigation, and free-breathing without navigation. Motion artifacts were scored for each sequence by two radiologists,showing fewer motion artifacts with navigation compared to free-breathing and greater motion artifacts than with breath-holding. This work demonstrates the feasibility and potential utility of navigation for pediatric abdominal T1-W imaging.

Magnetic resonance imaging for uterine and vaginal anomalies.

PURPOSE OF REVIEW: Pediatric pelvic MRI has had dramatic advances in the past few years. This review documents studies demonstrating the accuracy of MRI for the evaluation of uterine and vaginal anomalies and discusses the salient changes to MRI methods that are particularly applicable to evaluating the pediatric patient with these developmental anomalies. RECENT FINDINGS: MRI has high accuracy for evaluation of uterine and vaginal anomalies. Significant advances, such as volumetric imaging, increased resolution, decreased motion artifacts, and shorter examination time, have increased the access and utility of MRI for pediatric patients. SUMMARY: MRI techniques have evolved markedly in the past several years, providing a robust method of evaluating uterine and vaginal anomalies in the pediatric patient.

Automated identification of acute hepatitis B using electronic medical record data to facilitate public health surveillance.

BACKGROUND: Automatic identification of notifiable diseases from electronic medical records can potentially improve the timeliness and completeness of public health surveillance. We describe the development and implementation of an algorithm for prospective surveillance of patients with acute hepatitis B using electronic medical record data. METHODS: Initial algorithms were created by adapting Centers for Disease Control and Prevention diagnostic criteria for acute hepatitis B into electronic terms. The algorithms were tested by applying them to ambulatory electronic medical record data spanning 1990 to May 2006. A physician reviewer classified each case identified as acute or chronic infection. Additional criteria were added to algorithms in serial fashion to improve accuracy. The best algorithm was validated by applying it to prospective electronic medical record data from June 2006 through April 2008. Completeness of case capture was assessed by comparison with state health department records. FINDINGS: A final algorithm including a positive hepatitis B specific test, elevated transaminases and bilirubin, absence of prior positive hepatitis B tests, and absence of an ICD9 code for chronic hepatitis B identified 112/113 patients with acute hepatitis B (sensitivity 97.4%, 95% confidence interval 94-100%; specificity 93.8%, 95% confidence interval 87-100%). Application of this algorithm to prospective electronic medical record data identified 8 cases without false positives. These included 4 patients that had not been reported to the health department. There were no known cases of acute hepatitis B missed by the algorithm. CONCLUSIONS: An algorithm using codified electronic medical record data can reliably detect acute hepatitis B. The completeness of public health surveillance may be improved by automatically identifying notifiable diseases from electronic medical record data.

Hepatitis C prevention with nurses.

A state campaign to educate nurses about hepatitis C and encourage nurses to fight the epidemic provided an opportunity to assess the relationship between information and safety practices. Baseline and follow-up surveys were sent to random, representative samples (n = 6000) of licensed nurses in Massachusetts, USA. Responses received by 42% (n = 2443) at baseline and 37% (n = 2167) at follow-up were compared to explore the relationship between receiving information and propensity to counsel patients or use safety equipment. Only data from nurses in direct patient care were analyzed. Although few changes were observed, the assessment provided further evidence that more than a single intervention is needed to achieve health behavior change. The number of nurses who never used safety equipment did decrease slightly, from 13.3% (191) to 8.2% (132), and nurses who received information were more likely to talk to patients about the virus: 49% (414) compared to 21% (120). Hepatitis information aimed at nurses may help control this emerging epidemic.

The Massachusetts HIV, hepatitis, addiction services integration (HHASI) experience: responding to the comprehensive needs of individuals with co-occurring risks and conditions.

Categorical funding mechanisms traditionally used to fund public health programs are a challenge to providers serving individuals with complex needs that often span multiple service areas. Integration--a formalized, collaborative process among service systems--responds to the challenge by decreasing fragmentation of care and improving coordination. In 2000, the Massachusetts Department of Public Health (MDPH) received a one-year planning grant from the federal Substance Abuse and Mental Health Services Administration (SAMHSA) to evaluate opportunities for integrating HIV/AIDS programs and substance abuse treatment programs. The project was later expanded to include viral hepatitis programming. Outcomes include the development of a strategic plan, joint procurement initiatives, and an ongoing commitment to sustain inter-bureau integration efforts, even in the face of substantial budget reductions. Integrated approaches can promote greater efficiency, improving communication and coordination among clients, providers, and government funding agencies.
