Searching PubMed during a Pandemic

BACKGROUND: The 2009 influenza A(H1N1) pandemic has generated thousands of articles and news items. However, finding relevant scientific articles in such rapidly developing health crises is a major challenge which, in turn, can affect decision-makers' ability to utilise up-to-date findings and ultimately shape public health interventions. This study set out to show the impact that the inconsistent naming of the pandemic can have on retrieving relevant scientific articles in PubMed/MEDLINE. METHODOLOGY: We first formulated a PubMed search algorithm covering different names of the influenza pandemic and simulated the results that it would have retrieved from weekly searches for relevant new records during the first 10 weeks of the pandemic. To assess the impact of failing to include every term in this search, we then conducted the same searches but omitted in turn "h1n1," "swine," "influenza" and "flu" from the search string, and compared the results to those for the full string. PRINCIPAL FINDINGS: On average, our core search string identified 44.3 potentially relevant new records at the end of each week. Of these, we determined that an average of 27.8 records were relevant. When we excluded one term from the string, the percentage of records missed out of the total number of relevant records averaged 18.7% for omitting "h1n1," 13.6% for "swine," 17.5% for "influenza," and 20.6% for "flu." CONCLUSIONS: Due to inconsistent naming, while searching for scientific material about rapidly evolving situations such as the influenza A(H1N1) pandemic, there is a risk that one will miss relevant articles. To address this problem, the international scientific community should agree on nomenclature and the specific name to be used earlier, and the National Library of Medicine in the US could index potentially relevant materials faster and allow publishers to add alert tags to such materials

Hepatitis C seropositivity among newly incarcerated prisoners in Estonia: data analysis of electronic health records from 2014 to 2015

BACKGROUND: Hepatitis C virus (HCV) infection is a widespread problem in prisons. The present study aimed to assess the prevalence of HCV seropositivity, HCV genotypes, factors associated with HCV seropositivity in newly incarcerated prisoners and to report experiences of treatment with pegylated interferon/ribavirin for HCV-positive inmates

An evaluation of self-management outcomes among chronic care patients in community home-based care programmes in rural Malawi: A 12-month follow-up study.

"This paper investigates the impact of community home-based care (CHBC) on self-management outcomes for chronically ill patients in rural Malawi. A pre- and post-evaluation survey was administered among 140 chronically ill patients with HIV and non-communicable diseases, newly enrolled in four CHBC programmes. We translated, adapted and administered scales from the Stanford Chronic Disease Self-Management Programme to evaluate patient's self-management outcomes (health status and self-efficacy), at four time points over a 12-month period, between April 2016 and May 2017. The patient's drop-out rate was approximately 8%. Data analysis included descriptive statistics, tests of associations, correlations and pairwise comparison of outcome variables between time points, and multivariate regression analysis to explore factors associated with changes in self-efficacy following CHBC interventions. The results indicate a reduction in patient-reported pain, fatigue and illness intrusiveness, while improvements in general health status and quality of life were not statistically significant. At baseline, the self-efficacy mean was 5.91, which dropped to 5.1 after 12\xC2\xA0months. Factors associated with this change included marital status, education, employment and were condition-related; whereby self-efficacy for non-HIV and multimorbid patients was much lower. The odds for self-efficacy improvement were lower for patients with diagnosed conditions of longer duration. CHBC programme support, regularity of contact and proximal location to other services influenced self-efficacy. Programmes maintaining regular home visits had higher patient satisfaction levels. Our findings suggest that there were differential changes in self-management outcomes following CHBC interventions. While self-management support through CHBC programmes was evident, CHBC providers require continuous training, supervision and sustainable funding to strengthen their contribution. Furthermore, sociodemographic and condition-related factors should inform the design of future interventions to optimise outcomes. This study provides a systematic evaluation of self-management outcomes for a heterogeneous chronically ill patient population and highlights the potential and relevant contribution of CHBC programmes in improving chronic care within sub-Saharan Africa.

Context matters: a qualitative study of the practicalities and dilemmas of delivering integrated chronic care within primary and secondary care settings in a rural Malawian district

Background: With the increasing double burden of communicable and non-communicable diseases (NCDs) in subSaharan Africa, health systems require new approaches to organise and deliver services for patients requiring longterm care. There is increasing recognition of the need to integrate health services, with evidence supporting integration of HIV and NCD services through the reorganisation of health system inputs, across system levels. This study investigates current practices of delivering and implementing integrated care for chronically-ill patients in rural Malawi, focusing on the primary level. Methods: A qualitative study on chronic care in Phalombe district conducted between April 2016 and May 2017, with a sub-analysis performed on the data following a document analysis to understand the policy context and how integration is conceptualised in Malawi; structured observations in five of the 15 district health facilities, selected purposively to represent different levels of care (primary and secondary), and ownership (private and public). Fifteen interviews with healthcare providers and managers, purposively selected from the above facilities. Meetings with five non-governmental organisations to study their projects and support towards chronic care in Phalombe. Data were analysed using a thematic approach and managed in NVivo. Results: Our study found that, while policies supported integration of various disease-specific programmes at point of care, integration efforts on the ground were severely hampered by human and health resource challenges e.g. inadequate consultation rooms, erratic supplies especially for NCDs, and an overstretched health workforce. There were notable achievements, though most prominent at the secondary level e.g. the establishment of a combined NCD clinic, initiating NCD screening within HIV services, and initiatives for integrated information systems. Conclusion: In rural Malawi, major impediments to integrated care provision for chronically-ill patients include the frail state of primary healthcare services and sub-optimal NCD care at the lowest healthcare level. In pursuit of integrative strategies, opportunities lie in utilising and expanding community-based outreach strategies offering multi-disease screening and care with strong referral linkages; careful task delegation and role realignment among care teams supported with proper training and incentive mechanisms; and collaborative partnership between public and private sector actors to expand the resource-base and promoting cross-programme initiatives

Patient–provider perspectives on self‐management support and patient empowerment in chronic care: A mixed‐methods study in a rural sub‐Saharan setting

Aim: To explore how provision of self‐management support to chronically‐ill patients in resource‐limited settings contributes to patient empowerment in chronic care. Design: Concurrent descriptive mixed methods research. Methods: A survey of 140 patients with chronic conditions administered at four time‐points in 12 months. We conducted 14 interviews and four focus‐group discus‐ sions with patients (N = 31); 13 healthcare provider interviews; and observations of four patient‐support group meetings. Data were collected between April 2016 ‐ May 2017 in rural Malawi. Qualitative data were analysed using a thematic approach and descriptive statistical analysis performed on survey data. Results: Healthcare professionals facilitated patient empowerment through health education, although literacy levels and environmental factors affected self‐manage‐ ment guidance. Information exchanged during patient–provider interactions varied and discussions centred around medical aspects and health promoting behaviour. Less than 40% of survey patients prepared questions prior to clinic consultations. Health education was often unstructured and delegated to non‐physician providers, mostly untrained in chronic care. Patients accessed psychosocial support from vol‐ unteer‐led community home‐based care programmes. HIV support‐groups regularly interacted with peers and practical skills exchanged in a supportive environment, reinforcing patient's self‐mangement competence and proactiveness in health care. Conclusion: For optimal self‐management, reforms at inter‐personal and organiza‐ tional level are needed including; mutual patient‐provider collaboration, diversifying access to self‐management support resources and restructuring patient support‐ groups to cater to diverse chronic conditions.Impact: Our study provides insights and framing of self‐management support and empowerment for patients in long‐term care in sub‐Saharan Africa. Lessons drawn could feed into designing and delivering responsive chronic care interventions

Changes to the national strategies, plans and guidelines for the treatment of hepatitis C in people who inject drugs between 2013 and 2016: a cross-sectional survey of 34 European countries

Background: Hepatitis C virus (HCV) infection is the leading cause of cirrhosis, end-stage liver disease and hepatocellular carcinoma (HCC) worldwide. In Europe, people who inject drugs (PWID) represent the majority of HCV infections, but are often excluded from treatment. The aim of this study was to report on national HCV strategies, action plans and guidelines in European countries that include HCV treatment for the general population as well as for PWID. Data on access to direct-acting antivirals (DAAs) were also collected. Methods: In 2016, 38 non-governmental organisations, universities and public health institutions that work with PWID in 34 European countries were invited to complete a 16-item online survey about current national HCV treatment policies and guidelines. Data from 2016 were compared to those from 2013 for 33 European countries, and time trends are presented. Differences in the data were analysed. Data from 2016 on general access to DAAs in PWID are presented separately. Results: The response rate was 100%. Fourteen countries (42%) reported having a national HCV strategy covering HCV treatment; 12 of these addressed HCV treatment for PWID. Respondents from ten countries (29%) reported having a national HCV action plan. PWID were specifically included in seven of them. Twenty-nine countries (85%) reported having national HCV treatment guidelines. PWID were specifically included in 23 (79%) of them. Compared to 2013, respondents reported that an additional seven countries (25%) had national strategies, an additional eight countries (29%) had action plans and an additional six countries (19%) had HCV treatment guidelines. However, PWID were not included in two, four and six of those countries, respectively. DAAs were reported to be available in 91% of the study countries, with restrictions reported in 71% of them. Conclusion: Respondents reported that fewer than half of the European countries in this study had a national HCV strategy and/or action plan, with even fewer including PWID. However, when compared to 2013, the number of such countries had slightly increased. Although PWID are often addressed in clinical guidelines, strategic action is needed to increase access to HCV treatment for this group and the situation should be regularly monitored

What do we know about inequalities in nafld distribution and outcomes?: A scoping review

With prevalence high and rising given the close relationship with obesity and diabetes mellitus, non-alcoholic fatty liver disease (NAFLD) is progressively becoming the most common chronic liver condition worldwide. However, little is known about the health inequalities in NAFLD distribution and outcomes. This review aims to analyze health inequalities in NAFLD distribution globally and to assess the health disparities in NAFLD-related outcomes. We conducted a scoping review of global health inequalities in NAFLD distribution and outcomes according to gender/sex, ethnicity/race, and socioeconomic position from PubMed’s inception to May 2021. Ultimately, 20 articles were included in the review, most (75%) of them carried out in the United States. Males were found to have a higher NAFLD prevalence (three articles), while available evidence suggests that women have an overall higher burden of advanced liver disease and complications (four articles), whereas they are less likely to be liver-transplanted once cirrhosis develops (one article). In the US, the Hispanic population had the highest NAFLD prevalence and poorer outcomes (seven articles), whereas Whites had fewer complications than other ethnicities (two articles). Patients with low socioeconomic status had higher NAFLD prevalence (four articles) and a higher likelihood of progression and complications (five articles). In conclusion, globally there is a lack of studies analyzing NAFLD prevalence and outcomes according to various axes of inequality through joint intersectional appraisals, and most studies included in our review were based on the US population. Available evidence suggests that NAFLD distribution and outcomes show large inequalities by social group. Further research on this issue is warranted.Fil: Talens, Mar.

Systematic Review of Interventions to Prevent the Spread of Sexually Transmitted Infections, Including HIV, Among Young People in Europe

Aim To examine the effectiveness of interventions seeking to prevent the spread of sexually transmitted infections (STIs), including HIV, among young people in the European Union. Methods For this systematic review, we examined interventions that aimed at STI risk reduction and health promotion conducted in schools, clinics, and in the community for reported effectiveness (in changing sexual behavior and/or knowledge) between 1995 and 2005. We also reviewed study design and intervention methodology to discover how these factors affected the results, and we compiled a list of characteristics associated with successful and unsuccessful programs. Studies were eligible if they employed a randomized control design or intervention-only design that examined change over time and measured behavioral, biologic, or certain psychosocial outcomes. Results Of the 19 studies that satisfied our review criteria, 11 reported improvements in the sexual health knowledge and/or attitudes of young people. Ten of the 19 studies aimed to change sexual risk behavior and 3 studies reported a significant reduction in a specific aspect of sexual risk behavior. Two of the interventions that led to behavioral change were peer-led and the other was teacher-led. Only 1 of the 8 randomized controlled trials reported any statistically significant change in sexual behavior, and then only for young females. Conclusion The young people studied were more accepting of peer-led than teacher-led interventions. Peerled interventions were also more successful in improving sexual knowledge, though there was no clear difference in their effectiveness in changing behavior. The improvement in sexual health knowledge does not necessarily lead to behavioral change. While knowledge may help improve health-seeking behavior, additional interventions are needed to reduce STIs among young peopl

Mining Social Media for Perceptions and Trends on HIV Pre-Exposure Prophylaxis

Pre-Exposure Prophylaxis (PrEP) is an approach for preventing the human immunodeficiency virus (HIV), which entails the administration of antiretroviral medication to high-risk seronegative persons. If taken correctly, PrEP can reduce HIV infection risk by more than 90%. The aim of this study was to identify and examine PrEP-related perceptions and trends discussed on Twitter. Using open-source technologies, text-mining and interactive visualisation techniques, a comprehensive data gathering and analytics Web-based platform was developed to facilitate the study objectives. Our results demonstrate that monitoring of PrEP-related discussions on Twitter can be detected over time and valuable insights can be obtained concerning issues of PrEP awareness, expressed opinions, perceived barriers and key discussion points on its adoption. The proposed platform could support public-health professionals and policy makers in PrEP monitoring, facilitating informed decision making and strategy planning for efficient HIV combination prevention
