RESUMO

The objectives of the study were to (i) document refugee, immigrant and migrant (RIM) communities' knowledge, attitudes and beliefs (KABs) related to the Coronavirus disease (COVID-19) vaccine and (ii) identify best practices for developing and disseminating culturally and linguistically responsive health messaging addressing those KABs. Thirteen online focus groups (OFGs) in 10 languages were conducted. Each OFG was conducted in the participants' native language. OFGs were recorded, transcribed, translated and uploaded to qualitative software for coding. A thematic analysis was conducted. Results suggest that while there was some variation between different language groups (e.g. whether religious leaders were seen as trusted sources of information about COVID), there were also important commonalities. Most language groups (i) alluded to hearing about or having gaps in knowledge about COVID-19/the COVID-19 vaccine, (ii) reported hearing negative or conflicting stories about the vaccine and (iii) shared concerns about the negative side effects of the vaccine. There continues to be a need for health messaging in RIM communities that is culturally and linguistically concordant and follows health literacy guidelines. Message content about the COVID-19 vaccine should focus on vaccine importance, effectiveness and safety, should be multimodal and should be primarily delivered by healthcare professionals and community members who have already been vaccinated.

RESUMO

Bereavement care in Europe varies in quality and availability. Through greater collaboration across Europe, there could potentially be an opportunity to improve care. This article discusses the inaugural European Grief Conference held in Denmark in 2022: "Bereavement and Grief in Europe - Emerging Perspectives & Collaborations". The conference was structured around a 4-tiered public health model of bereavement care needs. It included practice, research, policy, and educational perspectives. A total of 250 people from 27 different countries participated. To determine if the conference had appealed to a broad European audience of grief professionals and to assess how the conference was received by participants, we examined registration/submission data, the results of a one-word real-time feedback exercise, and the answers to an online satisfaction survey. The results indicated wide interest in greater information sharing and collaboration across Europe among bereavement care, research, and education professionals.

RESUMO

BACKGROUND: Losing a parent or spouse in adulthood may result in prolonged grief disorder (PGD) symptoms. PGD levels in parents may affect PGD levels in their adult offspring and the other way around. However, research on transmission of PGD in parent-child dyads is lacking. Consequently, we aimed to examine temporal associations between PGD levels in parent and adult children. METHODS: In doing so, we analyzed longitudinal self-report data on PGD levels (using the PG-13) assessed at 2, 11, 18, and 26 months after loss in 257 adult parent-child dyads from Denmark. Cross-lagged panel modeling was used for data-analyses. RESULTS: Changes in PGD levels in parents significantly predicted PGD levels in adult children, but not vice versa. Small through moderate cross-lagged effects (ß = 0.05 through 0.07) were found for PGD levels in parents predicting PGD levels in adult children at a subsequent time-point. These cross-lagged effects were found while taking into account the association between PGD levels in parents and adult children at the same time-point as well as the associations between the same construct over time and relevant covariates. CONCLUSIONS: Pending replication of these findings in clinical samples and younger families, our findings offer tentative support for expanding our focus in research and treatment of PGD from the individual to the family level.

RESUMO

BACKGROUND: Gender has been proposed as a potentially important predictor of bereavement outcomes. The majority of research in the field has explored this issue by examining gender differences in global grief severity. Findings have been mixed. In this study, we explore potential gender differences in grief using network analysis. This approach examines how individual symptoms relate to and reinforce each other, and so offers potential to shed light on novel aspects of grief expression across genders. METHOD: Graphical lasso networks were constructed using self-report data from 839 spousally bereaved older participants (584 female, 255 male) collected at 2- and 11- months post-bereavement. Edge strength, node strength and global network strength were compared to identify similarities and differences between gender networks across time. RESULTS: At both time points, the strongest connection for both genders was from yearning to pangs of grief. Yearning, pangs of grief, acceptance, bitterness and shock were prominent nodes at time 1. Numbness and meaninglessness emerged as prominent nodes at time 2. Males and females differed in the relative importance of shock at time 1, and the female network had greater overall strength than the male network at time 2. CONCLUSIONS: This study identified many similarities and few differences in the relationships between prolonged grief symptoms for males and females. Findings suggest that future studies should examine alternate sources of variation in grief outcomes. Limitations are discussed.

RESUMO

Prolonged Grief Disorder (PGD) is included in ICD-11 and DSM-5-TR and includes a requirement of cultural deviance. This study examined endorsement rates and factors associated with endorsement of this criterion among Danish bereaved spouses (n = 425) and their adult children (n = 159) four years post-loss. In total, 7.5% (n = 44) participants endorsed this criterion. Both including and excluding the criterion, the prevalence rates for probable DSM-5-TR PGD were 1.4% (n = 8) and 1.7% (n = 10), respectively and for probable ICD-11 PGD were 1.4% (n = 8) and 2.2% (n = 13), respectively. Age and gender of the deceased, age of the bereaved, greater grief severity, and comorbid psychopathology were positively associated with endorsement of the criterion. Findings demonstrate low endorsement of the cultural deviation criterion, that its inclusion excludes several potential PGD cases, and unanticipated associations with several factors raise questions about the criterion's validity.

RESUMO

This study explored relationships between school nurses' diabetes-related attitudes, self-efficacy in diabetes management and education, and care practices. One-hundred fourteen school nurses who have taken care of students with type 1 diabetes in public schools comprised this descriptive study sample. Participants completed online surveys. School nurses' diabetes-related attitudes were not related to their self-efficacy in diabetes education, but nurses' attitudes towards the psychosocial impact of diabetes were significantly related to their self-efficacy in diabetes management, and the number of students with diabetes was a significant contributor to this relationship. Nurses' full-time status and the type of school they worked in were significantly related to their self-efficacy in providing diabetes education. School nurses' positive attitudes about providing care for students with diabetes were related to having a higher level of self-efficacy in providing diabetes management. Based on the findings, recommendations are made for health consolidated schools and full-time school nurses.

RESUMO

BACKGROUND: Germline mutations in the BRCA1 or BRCA2 (BRCA) genes predispose to hereditary breast and ovarian cancer and, mostly in the case of BRCA2, are also prevalent in cases of pancreatic and prostate malignancies. Tumours from these patients tend to lose both copies of the wild-type BRCA gene, which makes them exquisitely sensitive to platinum drugs and poly(ADP-ribose) polymerase inhibitors (PARPi), treatments of choice in these disease settings. Reversion secondary mutations with the capacity of restoring BRCA protein expression have been documented in the literature as bona fide mechanisms of resistance to these treatments. PATIENTS AND METHODS: We analysed published sequencing data of BRCA genes (from tumour or circulating tumour DNA) in 327 patients with tumours harbouring mutations in BRCA1 or BRCA2 (234 patients with ovarian cancer, 27 with breast cancer, 13 with pancreatic cancer, 11 with prostate cancer and 42 with a cancer of unknown origin) that progressed on platinum or PARPi treatment. RESULTS: We describe 269 cases of reversion mutations in 86 patients in this cohort (26.0%). Detailed analyses of the reversion events highlight that most amino acid sequences encoded by exon 11 in BRCA1 and BRCA2 are dispensable to generate resistance to platinum or PARPi, whereas other regions are more refractory to sizeable amino acid losses. They also underline the key role of mutagenic end-joining DNA repair pathways in generating reversions, especially in those affecting BRCA2, as indicated by the significant accumulation of DNA sequence microhomologies surrounding deletions leading to reversion events. CONCLUSIONS: Our analyses suggest that pharmacological inhibition of DNA end-joining repair pathways could improve durability of drug treatments by preventing the acquisition of reversion mutations in BRCA genes. They also highlight potential new therapeutic opportunities when reversions result in expression of hypomorphic versions of BRCA proteins, especially with agents targeting the response to DNA replication stress.

RESUMO

BACKGROUND: Information concerning the health-related quality-of-life (HRQoL) consequences of colposcopy is limited, particularly over time. In a longitudinal study, we investigated women's HRQoL at 4, 8 and 12 months post colposcopy and the factors associated with this. METHODS: Women attending colposcopy at two large hospitals affiliated with the national screening programme in Ireland were invited to complete questionnaires at 4, 8 and 12 months post colposcopy. HRQoL was measured using the EQ-5D-3L and compared across a range of socio-demographic, clinical and attitudinal variables. A mixed-effects logistic multivariable model was employed to investigate associations between these variables and low HRQoL. RESULTS: Of 584 women initially recruited, 429, 343 and 303 completed questionnaires at 4, 8 and 12 months, respectively. The mean overall HRQoL score for the sample across all time points was 0.90 (SD 0.16). Approximately 18% of women experienced low HRQoL at each of the three time points. In multivariable testing, over the entire 12-month follow-up period, non-Irish nationals (OR 8.99, 95% CI 2.35-34.43) and women with high-grade referral cytology (OR 2.78, 95% CI 1.08-7.13) were at higher odds of low HRQoL. Women who were past (OR 0.20, 95% CI 0.07-0.58) or never (OR 0.42, 95% CI 0.16-1.12) smokers were at lower odds of low HRQoL than current smokers. As women's satisfaction with their healthcare increased their odds of experiencing low HRQoL fell (OR per unit increase 0.51, 95% CI 0.34-0.75). CONCLUSIONS: Women's HRQoL did not change over the 12 months post colposcopy, but some subgroups of women were at higher risk of experiencing low HRQoL. These subgroups may benefit from additional support.

RESUMO

Structural inequities and lack of resources put vulnerable refugee communities at great risk. Refugees flee their country of origin to escape persecution and flee from war, famine and torture. Resettled refugee communities become particularly vulnerable during times of crisis due to limited English proficiency and poor social determinants of health (SDOH), which create barriers to attaining and sustaining health and wellbeing for themselves and their families. The purpose of this case study was to evaluate SDOH among a refugee community in the Southeastern United States. We surveyed the community twice during a 1-year period to assess various elements of SDOH. Among a primarily African and Southeast Asian refugee community, 76% reported difficulty paying for food, housing and healthcare during the first round of surveys. During the second round of surveys at the beginning of the Coronavirus pandemic, 70% reported lost income; 58% indicated concern about paying bills. There was little change during the 12-month study period, showing that SDOH are an enduring measure of poor health and wellbeing for this vulnerable refugee community.

RESUMO

OBJECTIVES: To describe a cross-border foodborne outbreak of Shigella sonnei that occurred in Ireland and Northern Ireland (NI) in December 2016 whilst also highlighting the valuable roles of sales data and international collaboration in the investigation and control of this outbreak. STUDY DESIGN: A cross-border outbreak control team was established to investigate the outbreak. METHODS: Epidemiological, microbiological, and environmental investigations were undertaken. Traditional analytical epidemiological studies were not feasible in this investigation. The restaurant chain provided sales data, which allowed assessment of a possible increased risk of illness associated with exposure to a particular type of heated food product (product A). RESULTS: Confirmed cases demonstrated sole trimethoprim resistance: an atypical antibiogram for Shigella isolates in Ireland. Early communication and the sharing of information within the outbreak control team facilitated the early detection of the international dimension of this outbreak. A joint international alert using the European Centre for Disease Control's confidential Epidemic Intelligence Information System for Food- and Waterborne Diseases and Zoonoses (EPIS-FWD) did not reveal further cases outside of the island of Ireland. The outbreak investigation identified that nine of thirteen primary case individuals had consumed product A from one of multiple branches of a restaurant chain located throughout the island of Ireland. Product A was made specifically for this chain in a food production facility in NI. S. sonnei was not detected in food samples from the food production facility. Strong statistical associations were observed between visiting a branch of this restaurant chain between 5 and 9 December 2016 and eating product A and developing shigellosis. CONCLUSIONS: This outbreak investigation highlights the importance of international collaboration in the efficient identification of cross-border foodborne outbreaks and the value of using sales data as the analytical component of such studies.

RESUMO

Anaesthetists experience unique stressors, and recent evidence suggests a high prevalence of stress and burnout in trainee anaesthetists. There has been no in-depth qualitative analysis to explore this further. We conducted semi-structured interviews to explore contributory and potentially protective factors in the development of perceived stress, burnout, depression and low work satisfaction. We sampled purposively among participants in the Satisfaction and Wellbeing in Anaesthetic Training study, reaching data saturation at 12 interviews. Thematic analysis identified three overarching themes: factors enabling work satisfaction; stressors of being an anaesthetic trainee; and suggestions for improving working conditions. Factors enabling work satisfaction were patient contact; the privilege of enabling good patient outcomes; and strong support at home and work. Stressors were demanding non-clinical work-loads; exhaustion from multiple commitments; a 'love/hate' relationship, as trainees value clinical work but find the training burden immense; feeling 'on edge', even unsafe at work; and the changing way society sees doctors. Nearly all trainees discussed feeling some levels of burnout (which were high and distressing for some) and also high levels of perceived stress. However, trainees also experienced distinct elements of work satisfaction and support. Suggested recommendations for improvement included: allowing contracted hours for non-clinical work; individuals taking responsibility for self-care in and out of work; cultural acceptance that doctors can struggle; and embedding wellbeing support more deeply in organisations and the specialty. Our study provides a foundation for further work to inform organisational and cultural changes, to help translate anaesthetic trainees' passion for their work into a manageable and satisfactory career.

RESUMO

There is growing evidence that anaesthetic trainees experience, and may be particularly susceptible to, high levels of work stress, burnout and depression. This is concern for the safety and wellbeing of these doctors and for the patients they treat. To date, there has been no in-depth evaluation of these issues among UK anaesthetic trainees to examine which groups may be most affected, and to identify the professional and personal factors with which they are associated. We conducted an anonymous electronic survey to determine the prevalence of perceived stress, risk of burnout/depression and work satisfaction among anaesthetic trainees within South-West England and Wales, and explored in detail the influence of key baseline characteristics, lifestyle and anaesthetic training variables. We identified a denominator of 619 eligible participants and received 397 responses, a response rate of 64%. We observed a high prevalence of perceived stress; 37% (95%CI 32-42%), burnout risk 25% (21-29%) and depression risk 18% (15-23%), and found that these issues frequently co-exist. Having no children, > 3 days sickness absence in the previous year, ≤ 1 h.week-1 of exercise and > 7.5 h.week-1 of additional non-clinical work were independant predictors of negative psychological outcomes. Although female respondents reported higher stress, burnout risk was more likely in male respondents. This information could help in the identification of at-risk groups as well as informing ways to support these groups and to influence resource and intervention design. Targeted interventions, such as modification of exercise behaviour and methods of reducing stressors relating to non-clinical workloads, warrant further research.

RESUMO

PURPOSE: This study sought to determine if disparities in insulin pump therapy among youth with type 1 diabetes (T1DM) persist despite recent increases in overall pump use rates. DESIGN AND METHODS: All patients aged 6 months-17 years, diagnosed with T1DM, and completed 4+ outpatient diabetes visits at an academically-affiliated pediatric health care center from 2011 to 2016 were identified (n = 2131). Data were collected from existing electronic medical records and a multivariable logistic regression model was used to identify factors associated with insulin pump therapy. RESULTS: Findings revealed one novel factor (patients/families whose primary language is Spanish [OR 0.47, p = 0.038] or other non-English languages [OR 0.47, p = 0.028]) and confirmed several previously known factors associated with lower insulin pump use: patients who were older (10-14 years OR 0.38, p < 0.0001; 15+ years OR 0.15, p < 0.0001), male (OR 0.80, p = 0.021), non-Hispanic black (OR 0.59, p = 0.009), American Indian/Alaska Native (OR 0.19, p = 0.023), had either government (OR 0.42, p < 0.0001) or no insurance (OR 0.52, p = 0.004) and poor glycemic control (at least one HbA1c ≥ 8.5%; OR 0.54, p < 0.0001). CONCLUSION: Significant disparities in insulin pump use in youth with T1DM persist despite known benefits associated with pump therapy and underlying causes remain unclear. PRACTICE IMPLICATIONS: Health care providers should explore barriers to insulin pump therapy, including limited English language proficiency.

RESUMO

Aims Lifelong HIV infection has an unknown impact on bone health in children. In view of this, we aimed to improve management of vitamin D deficiency. Methods Three audits over 8 years (2009-2017) were performed with interventions introduced intermittently in an effort to improve vitamin D deficiency. The interventions included education, a change in vitamin D dose and brand to increase compliance and a shift to nursing led management. Results The most striking result was the eradication of patients with deficient vitamin D levels (<25nmol/L) in 2017. In 2009 and 2015, 15% and 9% were deficient. In the earlier two studies, only 15% had 'sufficient' (>50nmol) vitamin D levels. This increased to 71% in 2017. 10% of patients had levels greater than >120nmol/L, increasing risk of vitamin D toxicity. 67% of patients with insufficient vit D (25-50nmol/L) were prescribed a stat high dose vitamin D (120,000 IU) to help avoid adherence issues. Conclusions Sequential audits along with a shift to nurse led management were the most likely reasons for sustained improvement. Similar projects in all medical departments could improve clinical outcomes.

RESUMO

BACKGROUND: Intimacy is a key psychological problem in anorexia nervosa (AN). Empirical evidence, including neurobiological underpinnings, is however, scarce. OBJECTIVE: In this study, we evaluated various emotional stimuli including intimate stimuli experienced in patients with AN and non-patients, as well as their cerebral response. METHODS: Functional magnetic resonance imaging was conducted using stimuli with positive, neutral, negative and intimate content. Participants (14 AN patients and 14 non-patients) alternated between passive viewing and explicit emotion regulation. RESULTS: Intimate stimuli were experienced less positively in AN patients compared to non-patients. AN patients showed decreased cerebral responses in superior parietal cortices in response to positive and intimate stimuli. Intimate stimuli led to stronger activation of the orbitofrontal cortex, and lower activation of the bilateral precuneus in AN patients. Orbitofrontal responses decreased in AN patients during explicit emotion regulation. CONCLUSIONS: These results show that intimate stimuli are of particular importance in AN patients, who show experiential differences compared to non-patients and altered activation of orbitofrontal and parietal brain structures. This supports that AN patients have difficulties with intimacy, attachment, self-referential processing and body perception. LEVEL OF EVIDENCE: Level III, case-control study.

RESUMO

Background: BRCA1 and BRCA2 (BRCA1/2)-deficient tumors display impaired homologous recombination repair (HRR) and enhanced sensitivity to DNA damaging agents or to poly(ADP-ribose) polymerase (PARP) inhibitors (PARPi). Their efficacy in germline BRCA1/2 (gBRCA1/2)-mutated metastatic breast cancers has been recently confirmed in clinical trials. Numerous mechanisms of PARPi resistance have been described, whose clinical relevance in gBRCA-mutated breast cancer is unknown. This highlights the need to identify functional biomarkers to better predict PARPi sensitivity. Patients and methods: We investigated the in vivo mechanisms of PARPi resistance in gBRCA1 patient-derived tumor xenografts (PDXs) exhibiting differential response to PARPi. Analysis included exome sequencing and immunostaining of DNA damage response proteins to functionally evaluate HRR. Findings were validated in a retrospective sample set from gBRCA1/2-cancer patients treated with PARPi. Results: RAD51 nuclear foci, a surrogate marker of HRR functionality, were the only common feature in PDX and patient samples with primary or acquired PARPi resistance. Consistently, low RAD51 was associated with objective response to PARPi. Evaluation of the RAD51 biomarker in untreated tumors was feasible due to endogenous DNA damage. In PARPi-resistant gBRCA1 PDXs, genetic analysis found no in-frame secondary mutations, but BRCA1 hypomorphic proteins in 60% of the models, TP53BP1-loss in 20% and RAD51-amplification in one sample, none mutually exclusive. Conversely, one of three PARPi-resistant gBRCA2 tumors displayed BRCA2 restoration by exome sequencing. In PDXs, PARPi resistance could be reverted upon combination of a PARPi with an ataxia-telangiectasia mutated (ATM) inhibitor. Conclusion: Detection of RAD51 foci in gBRCA tumors correlates with PARPi resistance regardless of the underlying mechanism restoring HRR function. This is a promising biomarker to be used in the clinic to better select patients for PARPi therapy. Our study also supports the clinical development of PARPi combinations such as those with ATM inhibitors.

RESUMO

Hepatitis A infection results in a spectrum of illness from asymptomatic disease to severe fulminant hepatitis. Since 2000, <50 cases have been reported annually in Ireland. We report on an outbreak of hepatitis A associated with a childcare facility(CCF) in 2015 in Ireland. Between January and July 2015, 12 outbreak-associated symptomatic hepatitis A cases were identified, including one delayed, retrospective diagnosis. Seven (58%) cases were adults, eight (67%) were male, six of the adults required hospitalisation. All 12 cases were confirmed on serology and the four cases that were genotyped were identical on phylogenetic analysis. Potential environmental exposures and hygiene practices at the CCF were investigated. Outbreak control measures included the provision of: hepatitis A information, infection prevention advice, hepatitis A vaccination to 554 CCF contacts, and voluntary closure of the CCF for deep-cleaning and staff education. From a healthcare perspective1, outbreak control costs were in excess of €45 000. This outbreak illustrates the considerable adult morbidity that can occur in hepatitis A outbreaks, highlights the challenges in controlling a large CCF-associated outbreak and the importance of early recognition by clinicians of hepatitis A.

RESUMO

The purpose of the current study was to explore colorectal cancer survivors' information and support needs in relation to health concerns and health behaviour change. Face-to-face interviews were conducted with participants who had completed active treatment for cancer within the previous 2 years. Participants were colorectal cancer survivors (N = 24, men = 11, women = 13 M, age = 69.38 years, SD = 4.19) recruited from a hospital in Perth, Australia on the basis that they had existing morbidities that put them at increased risk of cardiovascular disease. Interview transcripts were analysed using thematic analysis. RESULTS: Five main themes emerged: bowel changes; Lack of knowledge concerning healthy eating and physical activity; conflicting information; desire for support; and, need for simple messages and strategies to stay healthy. Where dietary recommendations were provided, these were to resolve bowel problems rather than to promote healthy eating. The provision of lifestyle advice from the oncologists is limited and patients' lack knowledge of guidelines for diet and physical activity. Oncologists could provide patients with clear messages from the World Cancer Research Fund (); that is to increase physical activity and dietary fibre and reduce consumption of red meat, processed meat, alcohol and body fatness.

RESUMO

PURPOSE: This study sought to gain a greater understanding of perceptions related to barriers/facilitators for pediatric (ages 0-17) clinical research participation among East African immigrant community members. DESIGN AND METHODS: Community leader interviews (n = 6) and focus groups with lay members (n = 16) from the three largest East African communities in the Seattle area (Eritrean, Ethiopian and Somali) were conducted. Discussions were semi-structured based on existing barrier/facilitator research and analyzed using directed content analysis to identify major themes. RESULTS: Analysis revealed two novel barrier sub-themes: inadequate interpretation and translation of information even when services were available and a lack of adequate vocabulary in preferred languages. Participants also confirmed previously identified logistical barriers/facilitators (lack of knowledge regarding clinical research; time, cost, transportation, and child care challenges; providing incentives) and psychosocial barriers/facilitators (mistrust of research; cultural and/or religious differences; connecting benefits to the community; involving religious/community leaders or organizations and including community members on the research team; transparency in the research process; presenting results to the community) for clinical research participation among underrepresented groups. CONCLUSION: Perceptions of barriers/facilitators for pediatric clinical research participation among East African immigrants identified two novel sub-themes and confirmed those previously described by other underrepresented communities. PRACTICE IMPLICATIONS: To facilitate more inclusive research participation, researchers, nurses and other health care providers might consider ensuring adequate time for discussion of the research study and process, engaging the community in the research process, employing lay reviews of translated materials and/or oral consent processes, and other strategies outlined in the Inclusive Research Model.
