RESUMO

Forensic research and practice have historically focused on risk assessment and prevention. This risk-oriented paradigm is shifting towards a more recovery-oriented perspective. The aim of this scoping review is to provide an overview of research on the factors influencing rehabilitation and recovery and discuss the recovery paradigm in a forensic setting. We performed a systematic search of the literature from the past 10 years, in Pubmed, Cinahl and PsycInfo, on recovery and rehabilitation. All types of study designs were included. Data was analysed and charted using an Excel template with various data items of interest. Clinical, personal, social, functional and forensic factors were found to be of influence on recovery and rehabilitation. A number of these overlapped with factors of influence on recidivism and desistance, others did not. Most studies on recovery and rehabilitation focused on a clinical forensic setting. This study provides an overview of the current body of knowledge on the factors influencing recovery and rehabilitation in forensic clients, and encourages researchers and practitioners in their focus on the recovery paradigm in forensic care. The body of evidence on rehabilitation and recovery is not yet as profound as that on recidivism and desistance. More knowledge on recovery trajectories for offenders in prison or ambulatory care, for example, is required.

RESUMO

BACKGROUND: Coronavirus disease 2019 (COVID-19) results in debilitating long-term symptoms, often referred to as Post-Acute Sequelae of SARS-CoV-2 Infection (PASC), in a substantial subgroup of patients. One of the most prevalent symptoms following COVID-19 is severe fatigue. Prompt delivery of cognitive behavioural therapy (CBT), an evidence-based treatment that has shown benefit in reducing severe fatigue in other conditions, may reduce post-COVID-19 fatigue. Based on an existing CBT protocol, a blended intervention of 17 weeks, Fit after COVID, was developed to treat severe fatigue after the acute phase of infection with SARS-CoV-2. METHOD: The ReCOVer study is a multicentre 2-arm randomised controlled trial (RCT) to test the efficacy of Fit after COVID on severe post-infectious fatigue. Participants are eligible if they report severe fatigue 3 up to and including 12 months following COVID-19. One hundred and fourteen participants will be randomised to either Fit after COVID or care as usual (ratio 1:1). The primary outcome, the fatigue severity subscale of the Checklist Individual Strength (CIS-fatigue), is assessed in both groups before randomisation (T0), directly post CBT or following care as usual (T1), and at follow-up 6 months after the second assessment (T2). In addition, a long-term follow-up (T3), 12 months after the second assessment, is performed in the CBT group only. The primary objective is to investigate whether CBT will lead to a significantly lower mean fatigue severity score measured with the CIS-fatigue across the first two follow-up assessments (T1 and T2) as compared to care as usual. Secondary objectives are to determine the proportion of participants no longer being severely fatigued (operationalised in different ways) at T1 and T2 and to investigate changes in physical and social functioning, in the number and severity of somatic symptoms and in problems concentrating across T1 and T2. DISCUSSION: This is the first trial testing a cognitive behavioural intervention targeting severe fatigue after COVID-19. If Fit after COVID is effective in reducing fatigue severity following COVID-19, this intervention could contribute to alleviating the long-term health consequences of COVID-19 by relieving one of its most prevalent and distressing long-term symptoms.

RESUMO

BACKGROUND: Globally 90 % of transmission of Hepatitis B virus (HBV) is from mother-to child and occurs predominantly in resource limited countries where the prevalence of HBV is high. Transmission could be interrupted by timely vaccinations but coverage remains problematic in these areas. Low knowledge or awareness of HBV may play a part in low vaccination coverage. This study examines the provision of antenatal care counselling with a focus on HBV in two different regions of northern Thailand, Sarapee Hospital (SH), Chiang Mai, and Shoklo Malaria Research Unit (SMRU), Tak Province. METHODS: A mixed-methods sequential explanatory study design was used to evaluate antenatal services for migrants. Cross-sectional knowledge, attitude and practice (KAP) surveys were conducted immediately after counselling at first ANC contact, at 3-6 months after first ANC contact and at delivery. Surveys provided quantitative data, and qualitative methods included observations, focus group discussions (FGD) and in-depth interviews (IDI); analysed thematically to explore concepts of knowledge and understanding, attitude and practice of pregnant women and providers. RESULTS: Between September-2019 and May-2020, 757 women participated to KAP surveys, and 31 observations of counselling, 16 FGD and 9 IDI were conducted. KAP surveys showed in spite of low knowledge about HBV transmission, infection, or vaccination (correct response: SH 5.7 %, 9/157; SMRU 34.0 %, 204/600), most women (≥ 93 %, either site) understood they were screened for HBV and were willing to vaccinate infants for HBV. In explaining KAP survey results, qualitative analysis suggests counselling should: use the appropriate language; be tailored to the local health literacy level, provide only pertinent information, be repeated over the antenatal period; and attempt to ensure patient privacy (where possible). Programme effectiveness benefits from positive attitudes to screening and vaccinations and a high level of trust in the providers nevertheless participants provided good suggestions for improvements of the service. CONCLUSIONS: Limited knowledge of HBV among migrant women can be improved by counselling that emphasizes actionable knowledge such as vaccination schedule. Key improvements to the counselling process include training counsellors to conduct interactive counselling sessions in the woman's language, using appropriate visual aids and timely repetition over the course of the antenatal period.

RESUMO

BACKGROUND: The setting for providing assertive treatment (AT) has changed during the last 30 years in The Netherlands from assertive community treatment (ACT) and flexible assertive community treatment (FACT) to municipalities. The provision of AT varies between municipalities. AIM: Describing the concept of AT, the nature and size of the target group, and the reasons why people with severe mental illness (SMI) do not seek treatment and the place of AT in mental health care. METHOD: We used literature en available quantitative data. RESULTS: AT regularly provided by mental health care is required in patients with SMI and social problems who do not seek treatment. When mental health care and social care collaborate on the level of the patient, treatment and handling of social problems can strengthen each other. This collaboration prevents discontinuity of care and breaking a trusting relationship because patients do not need to be transferred from social service to mental health care or vice versa. AT is on the continuum of voluntarily to compulsory care.AT provided by mental health care (usually provided by FACT-teams) is indicated for SMI patients with social problems and who do not seek treatment. The size of the target group is around 5000 - 20.000 patients in The Netherlands. Reasons not to seek help for people with SMI include within person factor, mental health related factors, or factors related to the interaction of SMI patients and mental health. We advocate for AT to become a regular part of mental health care, and for mental health care and social domain professionals to collaborate on case level. Acting this way, mental health treatment and addressing social problems can reinforce each other and discontinuity of care and breaking a trusting relationship can be prevented. AT is on the continuum of voluntary to involuntary treatment. That is why we suggest AT to be a better term than assertive outreach. CONCLUSION: It is a given fact that not all patients with SMI and social problems seek treatment. By making AT a regular part of mental health services, we prevent discontinuity of care and we fill the gap between voluntarily and compulsory care.

RESUMO

BACKGROUND: Ethiopia has one of the worst podoconiosis rates in the world, affecting >1.5 million patients. We present our ethnographic film 'Tigist, the story of a girl with podoconiosis' and its potential use in tackling podoconiosis. METHODS: We conducted visual ethnography, consisting of video-recorded participant observations and interviews with seven patients, three healthcare workers and two podoconiosis experts. RESULTS: We acquired video recordings of social moments, the state of podoconiosis patients' bodies and minds, their emotions and the impact of poverty. CONCLUSIONS: Our film allows for an intensified understanding of patients' daily experiences with podoconiosis, potentially impacting care, awareness and medical teaching programs.

RESUMO

BACKGROUND: The aim of this manuscript is to highlight challenges in the implementation of maternal tenofovir disoproxil fumarate (tenofovir) for prevention of mother to child transmission (PMTCT) of hepatitis B virus (HBV) in resource limited setting. Current preventive strategies in resource-limited settings fail mainly due to prohibitive costs of hepatitis B immunoglobulin (HBIG) and a high proportion of homebirths, meaning both HBIG and hepatitis B birth dose vaccine are not given. A new strategy for PMTCT without the necessity of HBIG, could be daily tenofovir commenced early in gestation. Implementation challenges to early tenofovir for PMTCT can provide insight to elimination strategies of HBV as the burden of disease is high in resource-limited settings. METHODS: Challenges encountered during implementation of a study of tenofovir for PMTCT before 20 weeks gestation in rural and resource-limited areas on the Thailand-Myanmar border were identified informally from trial study logbooks and formally from comments from patients and staff at monthly visits. ClinicalTrials.gov Identifier: NCT02995005. MAIN BODY: During implementation 171 pregnant women were hepatitis B surface antigen (HBsAg) positive by point of-care test over 19 months (May-2018 until Dec-2019). In this resource-limited setting where historically no clinic has provided tenofovir for PMTCT of HBV, information provided by staff resulted in a high uptake of study screening (95.5% (84/88) when offered to pregnant women. False positive point-of-care rapid tests hinder a test and treat policy for HBV and development of improved rapid tests that include HBeAg and/or HBV DNA would increase efficiency. Integrated care of HBV to antenatal care, transport assistance and local agreements to facilitate access, could increase healthcare at this critical stage of the life course. As safe storage of medication in households in resource-limited setting may not be ideal, interactive counseling about this must be a routine part of care. CONCLUSION: Despite challenges, results from the study to date suggest tenofovir can be offered to HBV-infected women in resource-limited settings before 20 weeks gestation with a high uptake of screening, high drug accountability and follow-up, with provision of transportation support. This commentary has highlighted practical implementation issues with suggestions for strategies that support the objective of PMTCT and the World Health Organization goal of HBV elimination by 2030.

RESUMO

BACKGROUND: Community-based care for people with severe mental illness increasingly requires far-reaching cooperation between different domains. This cooperation must always be unique and local, and at the same time provide an answer to generic and nationally set goals.
AIM: Offering new insights on collaboration within and between domains.
METHOD: Reflection on developments in the social domain and specialist mental healthcare using relevant literature and recent (inter)national experiences.
RESULTS: It seems possible to provide better integral care by allowing FACT-teams to network together with Social Support partners (e.g. by sharing financial and/or human resources). In this process, networks of care for people with serious mental illness (SMI), develop over various phases and realize new partnerships. The model fidelity scale for FACT-teams was adjusted to facilitate that process. CONCLUSIONS The new FACT model fidelity scale is ready to allow FACT-teams to explore flexible local solutions for partnerships to realize the much-needed multi-domain integrated community care for people with SMI.

RESUMO

BACKGROUND: An important model for the organisation of care for people with severe mental illness is flexible assertive community treatment (F-ACT). F-ACT combines case management with assertive crisis intervention. Quality control was implemented in 2008 using a model fidelity scale. Research has shown that the norms used for the F-ACT fidelity scale no longer correspond with current norms concerning restorative and evidence-based care, as established in treatment guidelines.
AIM: To develop a new model fidelity scale for F-ACT teams.
METHOD: Using knowledge of experts, relevant articles and feedback from professionals, researchers, interest groups and family members, a new model fidelity scale was developed: the F-ACTs 2017. The revised scale was tested by trained auditors in 21 F-ACT teams and adjusted in two pilot rounds.
RESULTS: In 2017 the final version was presented to the stakeholders and was approved by the board of auditors; the final version is currently in use. CONCLUSIONS With the availability of F-ACTs 2017, the (research) field has state-of-the-art instrument to monitor the quality of care of persons with severe mental illness. It uses field standards to evaluate the degree of model fidelity of teams that focus on patients with severe mental illness in a rapidly changing context.

RESUMO

BACKGROUND: Vaccination remains the mainstay of prevention of hepatitis B virus (HBV) including birth dose and hepatitis B immunoglobulins (HBIGs). National estimates of vaccination coverage exclude migrants. The objective of this study is to investigate documentation practices of HBV-related infant vaccinations in Northern Thailand including migrants. METHODS: This is a retrospective review of hospital records of women who birthed infants in 2015 at Maharaj Nakorn Hospital, Chiang Mai (CM) or on the Thailand-Myanmar border, Tak. RESULTS: Of 2522 women, 987 were from CM (861 Thai nationals, 126 migrants) and 1535 were from Tak (651 Thai residence and 884 Myanmar residence). In CM, documentation for the birth dose vaccine (999 of 999, 100%) and HBIG was complete. In Tak, documentation was 1441 of 1549 (93%) for birth dose and 26 of 34 (76.5%) for HBIG, with missed opportunities including home delivery, delay in obtaining hepatitis B e-antigen status, and limitations of the records. Expanded Program of Immunization (EPI) documentation of 3 follow-up vaccinations dwindled with subsequent doses and distance, and complete documentation of 3 HBV EPI vaccines at the hospital of birth was low, 41.5% (1056 of 2547), but equitable for Thai or migrant status. CONCLUSIONS: This review provides strong support for excellent documentation of HBIG and birth dose vaccination in urban and rural settings, and in migrants, consistent with Thailand's vaccination policy and practice. Documentation of the 3 HBV EPI at the hospital of birth decreases with sequential doses, especially in families further away. Innovative data linkage is required to prove coverage and identify gaps.

RESUMO

BACKGROUND: The Flexible act (f-act) has been introduced in the Netherlands since 2004, alongside the Assertive Community Treatment (act) model. An estimate of 400 (f-)act teams concurrently provide care to approximately 70.000 people with serious mental illness. The ccaf has been assessing the model fidelity of act and f-act teams since 2009 to promote the quality and transparency of healthcare for clients with serious mental illness. OBJECTIVE To describe the state of implementation of f-act and associated trends in the Netherlands.
METHOD: Analysis of the ccaf database, which holds the data of audits conducted between 2009 and 2014.
RESULTS: The audits conducted by ccaf between 2009 and 2014 indicated an adequate implementation of f-act. The team foundations were well organized, featuring a multidisciplinary team structure, management of medication, practical support and investment in healthcare continuity, including during an admission. However, the results regarding participation and recovery were unsatisfactory. Furthermore, the results depicted a decline in the scores concerning a number of areas, including outreach and support of participation and recovery. CONCLUSIONS Although the data indicates an on average satisfactory implementation of f-act in the Netherlands, there are signs that the implementation of f-act is under pressure with relatively fewer home visits, a rising caseload and a reduced investment in recovery and participation. The findings are in accordance with the signs and arguments to adjust the emphasis on reducing hospital admissions, prioritizing the consolidation of outpatient care instead.

RESUMO

BACKGROUND: (Flexible) Assertive community treatment ((f)act) is applied increasingly to forensic psychiatric clients. However, evidence about the effectiveness of forensic (f)act is scanty. AIM: To investigate to what extent (subgroups of) clients receiving care from forensic (f)act teams show, after a year, changes in their social and psychological functioning and are subjected to fewer justicial outcome measures. METHOD: Between 2009 and 2011, eight forensic (f)act teams collected, at two measurement moments separated by an average of 12 months, data relating to client characteristics and outcomes of care. The study involved 202 clients. RESULTS: After a year clients showed significant improvements in psychological and social functioning, and had fewer confrontations with the police and the law. They were detained less often and for shorter periods and were considered to be less likely to reoffend. The number of admissions to mental health care and to addiction and forensic care remained constant. CONCLUSION: Clients with a psychiatric disorder and likely to display criminal behaviour showed improvement while being treated by forensic (f)act teams. Further research is needed to prove whether forensic (f)act treatment will have the desired effects in the longer term and will enjoy the status of being regarded as evidence based practice.

RESUMO

There is a paucity of data on the immune reconstitution inflammatory syndrome (IRIS) in the Central African region. We followed ART-naive HIV-infected patients initiating antiretroviral therapy in an HIV clinic in Gabon, for 6 months. Among 101 patients, IRIS was diagnosed in five. All IRIS cases were mucocutaneous manifestations. There were no cases of tuberculosis (TB) IRIS, but active TB (n = 20) was associated with developing other forms of IRIS (p = 0.02). Six patients died. The incidence of IRIS is low in Gabon, with mild, mucocutaneous manifestations.

RESUMO

We studied the use, uptake, and effects of e-Vita, a personal health record, with self-management support and personalized asynchronized coaching, for type 2 diabetes patients treated in primary care. Patients were invited by their practice nurse to join the study aimed at testing use and effects of a personal health record. Patients were followed up for 6 months. Uptake and usage were monitored using log data. Outcomes were self-reported diabetes self-care, diabetes-related distress, and emotional wellbeing. Patients' health status was collected from their medical chart. 132 patients agreed to participate in the study of which less than half (46.1%) did not return to the personal health record after 1st login. Only 5 patients used the self-management support program within the personal health record, 3 of whom asked a coach for feedback. Low use of the personal health record was registered. No statistical significant differences on any of the outcome measures were found between baseline and 6 month follow-up. This study showed minimal impact of implementing a personal health record including self-management support in primary diabetes care. Successful adoption of web-based platforms, as ongoing patient centered care, is hard to achieve without additional strategies aimed at enhancing patient motivation and engaging professionals.

RESUMO

ß1 Integrin-mediated cell-extracellular matrix interactions allow cancer cell survival and confer therapy resistance. It was shown that inhibition of ß1 integrins sensitizes cells to radiotherapy. Here, we examined the impact of ß1 integrin targeting on the repair of radiation-induced DNA double-strand breaks (DSBs). ß1 Integrin inhibition was accomplished using the monoclonal antibody AIIB2 and experiments were performed in three-dimensional cell cultures and tumor xenografts of human head and neck squamous cell carcinoma (HNSCC) cell lines. AIIB2, X-ray irradiation, small interfering RNA-mediated knockdown and Olaparib treatment were performed and residual DSB number, protein and gene expression, non-homologous end joining (NHEJ) activity as well as clonogenic survival were determined. ß1 Integrin targeting impaired repair of radiogenic DSB (γH2AX/53BP1, pDNA-PKcs T2609 foci) in vitro and in vivo and reduced the protein expression of Ku70, Rad50 and Nbs1. Further, we identified Ku70, Ku80 and DNA-PKcs but not poly(ADP-ribose) polymerase (PARP)-1 to reside in the ß1 integrin pathway. Intriguingly, combined inhibition of ß1 integrin and PARP using Olaparib was significantly more effective than either treatment alone in non-irradiated and irradiated HNSCC cells. Here, we support ß1 integrins as potential cancer targets and highlight a regulatory role for ß1 integrins in the repair of radiogenic DNA damage via classical NHEJ. Further, the data suggest combined targeting of ß1 integrin and PARP as promising approach for radiosensitization of HNSCC.

RESUMO

Due to differences in anatomy, primary rectal and colon cancer require different staging procedures, different neo-adjuvant treatment and different surgical approaches. For example, neoadjuvant radiotherapy or chemoradiotherapy is administered solely for rectal cancer. Neoadjuvant therapy and total mesorectal excision for rectal cancer might be responsible in part for the differing effect of adjuvant systemic treatment on overall survival, which is more evident in colon cancer than in rectal cancer. Apart from anatomic divergences, rectal and colon cancer also differ in their embryological origin and metastatic patterns. Moreover, they harbor a different composition of drug targets, such as v-raf murine sarcoma viral oncogene homolog B (BRAF), which is preferentially mutated in proximal colon cancers, and the epidermal growth factor receptor (EGFR), which is prevalently amplified or overexpressed in distal colorectal cancers. Despite their differences in metastatic pattern, composition of drug targets and earlier local treatment, metastatic rectal and colon cancer are, however, commonly regarded as one entity and are treated alike. In this review, we focused on rectal cancer and its biological and clinical differences and similarities relative to colon cancer. These aspects are crucial because they influence the current staging and treatment of these cancers, and might influence the design of future trials with targeted drugs.

RESUMO

There are over 150 known Sarcocystis species, and at least one is capable of infecting and causing disease in man. Extraintestinal (muscular) sarcocystosis and intestinal sarcocystosis are the two known manifestations of disease in humans. In this series of six cases and review, we focus on the invasive extraintestinal ("muscular") form of sarcocystosis in humans. This disease, which until recently was rarely described, has become relevant particularly as an imported condition in travelers due to a recent series of outbreaks reported from Malaysia. Human intestinal sarcocystosis is ubiquitous across the globe. However, absolute numbers of probable and particularly confirmed cases are few, with only several hundred described to date. Characteristically, patients exhibit signs and symptoms either 1-2 weeks after exposure, or after 4-8 weeks. Whether people remain asymptomatic or develop disease apparently depends on the infecting species, host factors, and the inoculum size. The definitive host(s) remain uncertain, and identification of the animal reservoir(s) requires further research. A better understanding of the epidemiology of the disease, as well as its immunological determinants, is hampered by the lack of reliable serological diagnostic methods. Additionally, DNA seems to be contained very effectively within the encysted parasite, thereby rendering PCR detection unreliable. Physicians should suspect the condition in patients with suggestive symptoms and a possible history of exposure. Surveillance networks for imported infectious diseases are formidable tools to help detect and localize outbreaks.

RESUMO

BACKGROUND: In recent years, requests for rabies immunoglobulin have increased at Amsterdam's Academic Medical Center's travel clinic. Travellers who received rabies pre-exposure prophylaxis (PrEP) before travel departure have immunological memory that can quickly be activated by timely booster vaccinations after possible exposure to rabies. PrEP alleviates the need for costly and scarcely available rabies immunoglobulin in case of exposure. This study describes which travellers are at risk of rabies exposure and would benefit from PrEP. The secondary aim was to specify which factors influence decision-making on taking PrEP. METHODS: We reviewed electronic patient files of travellers attending our clinic for rabies post-exposure prophylaxis between January 2009 and February 2014. Demographic and travel characteristics were compared with a sample of patients who were seen for pre-travel advice at our clinic. To assess which factors had influenced the decision to take PrEP, a questionnaire survey was conducted. RESULTS: A total of 161 travellers experienced animal-associated injury. Compared with travellers from the pre-travel database, more people travelled to Southeast Asia (49.5% vs. 30.9%, p = 0.035) for comparable time periods (median 21 vs. 21 days, p = 0.083). Transcutaneous injuries (type III) were common (73.9%), most often inflicted by dogs (45%). Only ten travellers (6.2%) had received PrEP. Barriers for PrEP were high costs and a short time interval between consultation and travel departure. CONCLUSION: Travellers t o Southeast Asia should particularly be informed about rabies and the possibility of PrEP. Long-term travel was not associated with a higher risk of rabies exposure.

RESUMO

Angiostrongylus cantonensis is the most common cause of eosinophilic meningitis. Although a rare condition among travelers, increased travel and global transportation of food products may result in more cases across non-endemic, developed countries in the future. We here describe two men with headache and painful skin after visiting the Philippines as presenting symptoms. Subsequently, confusion and focal neurologic symptoms developed. Both had increased serum eosinophils; however, CSF eosinophilia was only demonstrated after repeated lumbar puncture. In the CSF of both, Angiostrongylus spp. DNA was detected. Both were treated with albendazole combined with corticosteroids, after which symptoms improved.
