RESUMO

People from refugee and asylum seeker backgrounds resettling in Australia often experience intersecting risks for poor mental and physical health. Physical activity can promote better health outcomes, however there are limited programs tailored for this population. Therefore, understanding how to support refugees and asylum seekers to engage in physical activity is crucial. This paper aims to describe how the experience-based co-design (EBCD) process was used to identify priorities for a new physical activity service for refugees and asylum seekers. Using an EBCD framework we conducted qualitative interviews and co-design workshops with service users (refugees and asylum seekers living in the community) and service providers at a community Centre in Sydney, Australia. Sixteen participants, including eight service users and eight service providers engaged in the EBCD process over 12-months. The interviews revealed common themes or 'touchpoints' including barriers and enablers to physical activity participation such as access, safety and competing stressors. Subsequent co-design focus groups resulted in the establishment of five fundamental priorities and actionable strategies; ensuring cultural and psychological safety, promoting accessibility, facilitating support to access basic needs, enhancing physical activity literacy and fostering social connection. Using EBCD methodology, this study used the insights and lived experiences of both service users and providers to co-design a physical activity service for refugees and asylum seekers which is safe, supportive, social and accessible. The results of the implementation and evaluation of the program are ongoing.

RESUMO

BACKGROUND: Primary care clinicians have key responsibilities in obesity prevention and weight management. AIMS: We aimed to identify risk factors for developing obesity among people aged ≥45 years. METHODS: We conducted a record linkage longitudinal study of residents of metropolitan Sydney, Australia using data from the: (1) 45 and Up Study at baseline (2005-2009) and first follow-up (2012-2015); (2) Medicare claims; (3) Pharmaceutical Benefits Scheme; and (4) deaths registry. We examined risk factors for developing obesity (body mass index [BMI]: 30-40) at follow-up, separately for people within the: (1) healthy weight range (BMI 18.5-<25) and (2) overweight range (BMI 25-<30) at baseline. Covariates included demographics, modifiable behaviours, health status, allied health use, and medication use. Crude and adjusted relative risks were estimated using Poisson regression modelling. RESULTS: At follow-up, 1.1% (180/16,205) of those in the healthy weight range group, and 12.7% (1,939/15,266) of those in the overweight range group developed obesity. In both groups, the following were associated with developing obesity: current smoking at baseline, physical functioning limitations, and allied health service use through team care planning, while any alcohol consumption and adequate physical activity were found to be associated with a lower risk of developing obesity. In the healthy weight group, high psychological distress and the use of antiepileptics were associated with developing obesity. In the overweight group, female sex and full-time work were associated with developing obesity, while older age was found to be associated with a lower risk of developing obesity. CONCLUSIONS: These findings may inform the targeting of preventive interventions for obesity in clinical practice and broader public health programs.


Early intervention to prevent weight gain requires a targeted multidisciplinary team-based approach to improve diet, increase physical activity, and change behaviour. However, the capacity to provide this within primary care is limited and there is little funding for consultations with allied health professionals. There is a need to identify priority at-risk groups to help primary care clinicians target interventions to those in most need. We have identified, using a longitudinal study of residents of metropolitan Sydney, key characteristics of older adults who are at risk of gaining weight and developing obesity, including risk behaviours (smoking and physical inactivity), and chronic conditions or their treatment (physical function, psychological distress, and use of anti-epileptic medications). These findings may help alert clinicians to the need for preventive interventions in selected cases, as well as informing the targeting of public health programs.

RESUMO

INTRODUCTION: Patients with traumatic intracranial hemorrhage (tICH) are at increased risk of venous thromboembolism and may require anticoagulation. We evaluated the utility of surveillance computed tomography (CT) in patients with tICH who required therapeutic anticoagulation. METHODS: This single institution, retrospective study included adult patients with tICH who required anticoagulation within 4 weeks and had a surveillance head CT within 24 hours of reaching therapeutic anticoagulation levels. The primary outcome was hematoma expansion (HE) detected by the surveillance CT. Secondary outcomes included 1) changes in management in patients with HE on the surveillance head CT, 2) HE in the absence of clinical changes, and 3) mortality due to HE. We also compared mortality between patients who did and did not have a surveillance CT. RESULTS: Of 175 patients, 5 (2.9%) were found to have HE. Most (n = 4, 80%) had changes in management including anticoagulation discontinuation (n = 4), reversal (n = 1), and operative management (n = 1). Two patients developed symptoms or exam changes prior to the head CT. Of the 3 patients (1.7%) without preceding exam changes, each had only very minor HE and did not require operative management. No patient experienced mortality directly attributed to HE. There was no difference in mortality between patients who did and those who did not have a surveillance scan. CONCLUSIONS: Our findings suggest that most patients with tICH who are started on anticoagulation could be followed clinically, and providers may reserve CT imaging for patients with changes in exam/symptoms or those who have a poor clinical examination to follow.

RESUMO

INTRODUCTION: Pancreatic cancer recurrence following surgery is a significant challenge, and personalized surgical care is crucial. Topographical variations in pancreatic duct anatomy are frequent but often underestimated. This study aimed to investigate the potential importance of these variations in outcomes and patient survival after Whipple's procedures. METHODS: Data were collected from 105 patients with confirmed pancreatic head neoplasms who underwent surgery between 2008 and 2020. Radiological measurements of pancreatic duct location were performed, and statistical analysis was carried out using IBM SPSS. RESULTS: Inferior pancreatic duct topography was associated with an increased rate of metastatic spread and tumour recurrence. Additionally, inferior duct topography was associated with reduced overall and recurrence-free survival. Posterior pancreatic duct topography was associated with decreased incidence of perineural sheet infiltration and improved overall survival. DISCUSSION: These findings suggest that topographical diversity of pancreatic duct location can impact outcomes in Whipple's procedures. Intraoperative review of pancreatic duct location could help surgeons define areas of risk or safety and deliver a personalized surgical approach for patients with beneficial or deleterious anatomical profiles. This study provides valuable information to improve surgical management by identifying high-risk patients and delivering a personalized surgical approach with prognosis stratification.

RESUMO

BACKGROUND: The HeLP-GP trial aimed to increase the capacity of practice nurses to deliver weight management to overweight and obese patients through an intervention comprising a health check, a lifestyle app and/or telephone coaching. This paper describes implementation through the lens of organisational readiness with emphasis on the role of the practice nurse. METHODS: Routinely collected mixed method research data including practice surveys, field notes, and diaries and process data were mapped against the domains: motivation to implement, general capacity and intervention-specific capacity. RESULTS: Organisational readiness varied considerably, particularly the domain of intervention-specific capacity. Practice nurse turnover negatively impacted the implementation, affecting half of the practices. We observed a general lack of practice-based support for intervention delivery, and varying levels of interest, skill and confidence in delivering the intervention. Nurses struggled to complete the research and intervention tasks in a timely way. Conducting risk assessments and referring to coaching were generally not problematic; however, we noted lower confidence levels with the lifestyle app and instructing patients to use it. CONCLUSIONS: We found a lack of general 'readiness' inherent in the nursing role, particularly related to their capacity to complete intervention tasks and practice-level support to implement the intervention. For nurses in general practice to fulfil their potential in supporting patients to reduce risk and adopt healthier life choices, our study indicates that more could be done to improve their workforce positioning and remuneration, which may, in turn, improve continuity of care, retention and individual motivation.

RESUMO

CONTEXT: Patients with Turner Syndrome often present with short stature and ovarian insufficiency. The optimal method of pubertal induction to maximize adult height (AH) is unknown. OBJECTIVE: To identify variables related to pubertal induction that are associated with growth and AH. DESIGN & SETTING: Retrospective cohort analysis of patients attending a specialized Turner Syndrome clinic at a quaternary children's hospital. PATIENTS: Patients with Turner Syndrome (n=107) who attended the clinic between 2015 and 2021. Of these, 51 received estradiol for pubertal induction. MAIN OUTCOME MEASURES: Change in height standard deviation score (ΔHeightSDS) during pubertal induction, and AH. METHODS: Age at pubertal induction, bone age delay, midparental height (MPH), growth hormone treatment, and karyotype were assessed as predictors of AH and ΔHeightSDS. Associations between karyotype and comorbidities were also assessed. RESULTS: AH was predicted by MPH (0.8cm/cm, P=0.0001) and bone age delay (-1.84 cm/year, P= 0.006). ΔHeightSDS was predicted by growth hormone dose (0.09 SDS/mg/m2/week; P=0.017), bone age delay (-1.37 SDS/year; P=0.003), and age at pubertal induction (0.44 SDS/year; P=0.001). There was an interaction between bone age delay and pubertal induction age (P=0.013), with the combination of younger age at pubertal induction and a less-delayed bone age associated with a lower ΔHeightSDS. Karyotype did not influence AH or ΔHeightSDS, but did affect rates of other comorbidities. CONCLUSIONS: Decisions around timing of pubertal induction in patients with Turner Syndrome should be tailored to the individual. The current approach to estrogen supplementation needs to be refined in order to facilitate pubertal induction in a physiological manner without compromising height.

RESUMO

INTRODUCTION: The objective of this parallel group, randomised controlled trial is to evaluate a community health navigator (CHN) intervention provided to patients aged over 40 years and living with chronic health conditions to transition from hospital inpatient care to their homes. Unplanned hospital readmissions are costly for the health system and negatively impact patients. METHODS AND ANALYSIS: Patients are randomised post hospital discharge to the CHN intervention or usual care. A comparison of outcomes between intervention and control groups will use multivariate regression techniques that adjust for age, sex and any independent variables that are significantly different between the two groups, using multiple imputation for missing values. Time-to-event analysis will examine the relationship between seeing a CHN following discharge from the index hospitalisation and reduced rehospitalisations in the subsequent 60 days and 6 months. Secondary outcomes include medication adherence, health literacy, quality of life, experience of healthcare and health service use (including the cost of care). We will also conduct a qualitative assessment of the implementation of the navigator role from the viewpoint of stakeholders including patients, health professionals and the navigators themselves. ETHICS APPROVAL: Ethics approval was obtained from the Research Ethics and Governance Office, Sydney Local Health District, on 21 January 2022 (Protocol no. X21-0438 and 2021/ETH12171). The findings of the trial will be disseminated through peer-reviewed journals and national and international conference presentations. Data will be deposited in an institutional data repository at the end of the trial. This is subject to Ethics Committee approval, and the metadata will be made available on request. TRIAL REGISTRATION NUMBER: Australian New Zealand Clinical Trials Registry (ACTRN 12622000659707). ARTICLE SUMMARY: The objective of this trial is to evaluate a CHN intervention provided to patients aged over 40 years and living with chronic health conditions to transition from hospital inpatient care to their homes.

RESUMO

BACKGROUND: The Health eLiteracy for Prevention in General Practice trial is a primary health care-based behavior change intervention for weight loss in Australians who are overweight and those with obesity from lower socioeconomic areas. Individuals from these areas are known to have low levels of health literacy and are particularly at risk for chronic conditions, including diabetes and cardiovascular disease. The intervention comprised health check visits with a practice nurse, a purpose-built patient-facing mobile app (mysnapp), and a referral to telephone coaching. OBJECTIVE: This study aimed to assess mysnapp app use, its user profiles, the duration and frequency of use within the Health eLiteracy for Prevention in General Practice trial, its association with other intervention components, and its association with study outcomes (health literacy and diet) to determine whether they have significantly improved at 6 months. METHODS: In 2018, a total of 22 general practices from 2 Australian states were recruited and randomized by cluster to the intervention or usual care. Patients who met the main eligibility criteria (ie, BMI>28 in the previous 12 months and aged 40-74 years) were identified through the clinical software. The practice staff then provided the patients with details about this study. The intervention consisted of a health check with a practice nurse and a lifestyle app, a telephone coaching program, or both depending on the participants' choice. Data were collected directly through the app and combined with data from the 6-week health check with the practice nurses, the telephone coaching, and the participants' questionnaires at baseline and 6-month follow-up. The analyses comprised descriptive and inferential statistics. RESULTS: Of the 120 participants who received the intervention, 62 (52%) chose to use the app. The app and nonapp user groups did not differ significantly in demographics or prior recent hospital admissions. The median time between first and last app use was 52 (IQR 4-95) days, with a median of 5 (IQR 2-10) active days. App users were significantly more likely to attend the 6-week health check (2-sided Fisher exact test; P<.001) and participate in the telephone coaching (2-sided Fisher exact test; P=.007) than nonapp users. There was no association between app use and study outcomes shown to have significantly improved (health literacy and diet) at 6 months. CONCLUSIONS: Recruitment and engagement were difficult for this study in disadvantaged populations with low health literacy. However, app users were more likely to attend the 6-week health check and participate in telephone coaching, suggesting that participants who opted for several intervention components felt more committed to this study.

RESUMO

BACKGROUND: People with lived experience of severe mental illness (PWLE) live around 20years less than the general population. Most deaths are due to preventable health conditions. Improved access to high-quality preventive health care could help reduce this health inequity. This study aimed to answer the question: What helps PWLE access preventive care from their GP to prevent long-term physical conditions? METHODS: Qualitative interviews (n=10) and a focus group (n=10 participants) were conducted with PWLE who accessed a community mental health service and their carers (n=5). An asset-based framework was used to explore what helps participants access and engage with a GP. A conceptual framework of access to care guided data collection and analysis. Member checking was conducted with PWLE, service providers and other stakeholders. A lived experience researcher was involved in all stages of the study. RESULTS: PWLE and their carers identified multiple challenges to accessing high-quality preventive care, including the impacts of their mental illness, cognitive capacity, experiences of discrimination and low income. Some GPs facilitated access and communication. Key facilitators to access were support people and affordable preventive care. CONCLUSION: GPs can play an important role in facilitating access and communication with PWLE but need support to do so, particularly in the context of current demands in the Australian health system. Support workers, carers and mental health services are key assets in supporting PWLE and facilitating communication between PWLE and GPs. GP capacity building and system changes are needed to strengthen primary care's responsiveness to PWLE and ability to engage in collaborative/shared care.

RESUMO

Objective: We aimed to elucidate associations between geographic location, size, and ranking of medical schools that orthopaedic surgery residents graduate from and the residencies that they match both pre-COVID-19 and post-COVID-19 pandemic by examining the 2017 to 2022 orthopaedic surgery residency cohorts. Methods: Demographics were extracted using Doximity Residency Navigator platform, the 2021 US News and World Report, and program websites. Medical schools were classified as large if they had >613 medical students. Postgraduate year 1 (PGY-1) (2021 match) and PGY-2 (2022 match) residents were classified as the COVID-19 cohort. Location was categorized as Northeast, Midwest, South, and West. Chi-square tests, Cohen's H value, and descriptive statistics were used for analysis with statistical significance set at p <0.05. Results: Four thousand two hundred forty-three residents from 160 accredited US orthopaedic residency programs (78.4%) were included. Northeastern applicants were most likely to match in the same region (p <0.01), and southern applicants were most likely to match at their home program (p <0.001). Applicants affected by the COVID-19 pandemic did not differ from their predecessors with regards to matching to the same region (p = 0.637) or home program (p = 0.489). Applicants from public medical schools were more likely to match in the same region and at their home program (p <0.001), whereas those from private medical schools were more likely to match at top-ranked residencies (p <0.001). Students from both top 25- and top 50-ranked medical schools were more likely to match at their home program (p <0.01) and attend top 20-ranked residency programs (p <0.0001). Conclusion: These results demonstrate significant associations between matched residencies and attended medical schools' geographic location, school type, and ranking. During the pandemic, geographic trends were overall unchanged, whereas residents from large or lower-ranked schools were more likely to match at home programs, and those from private or top-ranked schools were less likely to attend top residencies.

RESUMO

High quality, long term follow-up care for cancer patients needs to be coordinated, comprehensive and tailored to the diverse needs of patients. This study implemented shared follow-up care using an interactive e-care plan that provided a collaborative space to schedule and share goals, tasks and information and support the monitoring of care. Qualitative results identified good relational coordination. Increasing communication from the cancer service is important.

RESUMO

PURPOSE: Prostate artery embolisation (PAE) is a key treatment for the management of symptomatic benign prostatic hyperplasia (BPH). Common cardiovascular risk factors might be associated with suboptimal outcomes and thus influence patient treatment selection. The aim of the study was to evaluate whether cardiovascular comorbidities affect PAE outcomes. METHODS: Retrospective subset analysis of the UK Registry of Prostate Artery Embolisation (UK-ROPE) database was performed with patients who had a full documented past medical histories including hypertension, diabetes, coronary artery disease (CAD), diabetes and smoking status as well as international prostate symptom score (IPSS) at baseline and at 12 months. Multiple regression was performed to assess for any significant predictors. RESULTS: Comorbidity data were available for 100/216 patients (mean age 65.8 ± 6.4 years), baseline IPSS 20.9 ± 7.0). Regression analysis revealed that the presence of hypertension (53.7% IPSS reduction vs. absence 51.4%, p = 0.94), diabetes (52.6% vs. absence 52.1%, p = 0.6), CAD (59.2% vs. absence 51.4%, p = 0.95), no comorbidities (49.8% vs. any comorbidity present 55.3%, p = 0.66), smoking status (non-smoker, 52.6%, current smoker, 61.5%, ex-smoker, 49.8%, p > 0.05), age (p = 0.52) and baseline Qmax (p = 0.41) did not significantly impact IPSS reduction at 12 months post-PAE. Baseline prostate volume significantly influenced IPSS reduction (≥ 80 cc prostates, 58.9% vs. < 80 cc prostates 43.2%, p < 0.05). CONCLUSION: The presence of cardiovascular comorbidities/smoking history does not appear to significantly impact PAE symptom score outcomes at 12 months post procedure. Our findings suggest that if the prostatic artery can be accessed, then clinical success is comparable to those without cardiovascular comorbidities.

RESUMO

Pt(II) and Pd(II) coordinating N-donor ligands have been extensively studied as anticancer agents after the success of cisplatin. In this work, a novel bidentate N-donor ligand, the N-[[4-(phenylmethoxy)phenyl]methyl]-2-pyridinemethanamine, was designed to explore the antiparasitic, antiviral and antitumor activity of its Pt(II) and Pd(II) complexes. Chemical and spectroscopic characterization confirm the formation of [MLCl2 ] complexes, where M=Pt(II) and Pd(II). Single crystal X-ray diffraction confirmed a square-planar geometry for the Pd(II) complex. Spectroscopic characterization of the Pt(II) complex suggests a similar structure. 1 H NMR, 195 Pt NMR and HR-ESI-MS(+) analysis of DMSO solution of complexes indicated that both compounds exchange the chloride trans to the pyridine for a solvent molecule with different reaction rates. The ligand and the two complexes were tested for in vitro antitumoral, antileishmanial, and antiviral activity. The Pt(II) complex resulted in a GI50 of 10.5 µM against the NCI/ADR-RES (multidrug-resistant ovarian carcinoma) cell line. The ligand and the Pd(II) complex showed good anti-SARS-CoV-2 activity with around 65 % reduction in viral replication at a concentration of 50 µM.

RESUMO

BACKGROUND: Primary health care [PHC] services with general practitioners (GPs) as the first point of access to health care services for people from refugee backgrounds in Australia can play a crucial role in building health literacy and promoting access to culturally appropriate services. To achieve equitable access and engagement, services and systems must be responsive to diverse health literacy and cultural needs. This study aims to explore how primary health services respond as a system and organisation to the health literacy and cultural needs of people from refugee backgrounds in Australia. METHODS: This exploratory qualitative study involved 52 semi-structured interviews among 19 Africans from refugee backgrounds, 14 service providers, including GPs and nurses, and 19 other stakeholders, such as service managers/directors. Participants resided in New South Wales, Victoria, and Queensland. Interviews were audio-recorded, transcribed, and coded into QSR NVivo 12. Data analysis was guided by reflexive thematic analysis. FINDINGS: Three interrelated themes were identified from the data relating to the health literacy and cultural responsiveness of PHC systems and services. The first theme, 'variable and ad hoc organisational response to health literacy and culturally responsive care,' demonstrated that some organisations did not systematically address the inherent complexity of navigating the health system nor the capacity of services and providers to respond to the cultural needs of people from refugee backgrounds. The second theme, 'individual provider responsibility,' captured the individual providers' interpersonal and relational efforts in supporting the health literacy and cultural needs of people from refugee backgrounds based on their motivation and adaptation. The third theme, 'refugee patient responsibility,' encapsulated people from refugee backgrounds' adaptations to and learning of the health system to navigate and access services. CONCLUSION: Health literacy and culturally responsive practices need to be systematised by PHC organisations to be implemented and sustained over time. There is a need for diversity in the organisational leadership and health care workforce, organisational commitment, health literacy and culturally responsive care policies, provider training, and auditing practice as essential components of the change process. Engaging with refugee communities would allow services to focus on people from refugee backgrounds' needs by design.

RESUMO

Hepatitis E virus (HEV) is an emerging pathogen responsible for more than 20 million cases of acute hepatitis globally per annum. Healthy individuals typically have a self-limiting infection, but mortality rates in some populations such as pregnant women can reach 30 %. A detailed understanding of the virus lifecycle is lacking, mainly due to limitations in experimental systems. In this regard, the cyclophilins are an important family of proteins that have peptidyl-prolyl isomerase activity and play roles in the replication of a number of positive-sense RNA viruses, including hepatotropic viruses such as hepatitis C virus (HCV). Cyclophilins A and B (CypA/B) are the two most abundant Cyps in hepatocytes and are therefore potential targets for pan-viral therapeutics. Here, we investigated the importance of CypA and CypB for HEV genome replication using sub-genomic replicons. Using a combination of pharmacological inhibition by cyclosporine A (CsA), and silencing by small hairpin RNA we find that CypA and CypB are not essential for HEV replication. However, we find that silencing of CypB reduces replication of some HEV isolates in some cells. Furthermore, sensitivity to Cyp silencing appears to be partly conferred by the sequence within the hypervariable region of the viral polyprotein. These data suggest HEV is atypical in its requirements for cyclophilin for viral genome replication and that this phenomenon could be genotype- and sequence-specific.

RESUMO

Aims: Scoliosis is a lateral curvature of the spine with associated rotation, often causing distress due to appearance. For some curves, there is good evidence to support the use of a spinal brace, worn for 20 to 24 hours a day to minimize the curve, making it as straight as possible during growth, preventing progression. Compliance can be poor due to appearance and comfort. A night-time brace, worn for eight to 12 hours, can achieve higher levels of curve correction while patients are supine, and could be preferable for patients, but evidence of efficacy is limited. This is the protocol for a randomized controlled trial of 'full-time bracing' versus 'night-time bracing' in adolescent idiopathic scoliosis (AIS). Methods: UK paediatric spine clinics will recruit 780 participants aged ten to 15 years-old with AIS, Risser stage 0, 1, or 2, and curve size (Cobb angle) 20° to 40° with apex at or below T7. Patients are randomly allocated 1:1, to either full-time or night-time bracing. A qualitative sub-study will explore communication and experiences of families in terms of bracing and research. Patient and Public Involvement & Engagement informed study design and will assist with aspects of trial delivery and dissemination. Discussion: The primary outcome is 'treatment failure' (Cobb angle progression to 50° or more before skeletal maturity); skeletal maturity is at Risser stage 4 in females and 5 in males, or 'treatment success' (Cobb angle less than 50° at skeletal maturity). The comparison is on a non-inferiority basis (non-inferiority margin 11%). Participants are followed up every six months while in brace, and at one and two years after skeletal maturity. Secondary outcomes include the Scoliosis Research Society 22 questionnaire and measures of quality of life, psychological effects of bracing, adherence, anxiety and depression, sleep, satisfaction, and educational attainment. All data will be collected through the British Spine Registry.

RESUMO

OBJECTIVE: The present study aims to measure the prevalence of non-disabled frailty and its associated factors among Bangladeshi older adults. METHODS: This cross-sectional study was conducted during September and October 2021 among 1,045 Bangladeshi older adults (≥60 years). Telephone interviews, using a semi-structured questionnaire, were undertaken to collect data on participants' characteristics and level of frailty. The non-disabled frailty was measured using the 'Frail Non-Disabled (FiND)' questionnaire. A multinomial logistic regression model assessed the factors associated with frailty among the participants. RESULTS: Around a quarter of the participants (24.8%) were frail. The multinomial regression analysis showed that older participants aged ≥80 years (RRR = 3.23, 95% CI: 1.41-7.37) were more likely to be frail compared to participants aged 60-69 years. Likewise, the participants living in a large family with ≥4 members (RRR = 1.39, 95% CI: 1.01-1.92) were more likely to be frail compared to those living in smaller families. Also, participants having memory or concentration problems (RRR = 1.56, 95% CI: 1.12-2.17) were more likely to be frail compared to those who were not suffering from these problems. Moreover, participants whose family members were non-responsive to their day-to-day assistance (RRR = 1.47, 95% CI: 1.06-2.03) were more likely to be frail compared to those whose family members were responsive. Furthermore, participants who were feeling lonely (RRR = 1.45, 95% CI: 1.07-1.98) were more likely to be frail than their counterparts who were not feeling lonely. CONCLUSIONS: The findings of the present study suggest developing tailored interventions to address the burden of frailty among the older populations in Bangladesh. In particular, providing long-term care and health promotion activities can be of value in preventing frailty and reducing adverse health outcomes among this vulnerable population group.

RESUMO

OBJECTIVE: Antifibrinolytics, such as tranexamic acid (TXA), have been shown to decrease intraoperative blood loss across multiple surgical disciplines. However, they carry the theoretical risk of thromboembolic events secondary to induced hypercoagulability. Therefore, the aim of this study was to systematically review the available literature and perform a meta-analysis on the use of TXA in meningioma resection to assess thromboembolic risks. METHODS: The PubMed, Web of Science, and Google Scholar databases were reviewed for all randomized controlled trials presenting primary data on TXA use during resection of intracranial meningiomas. Data were gathered on operative duration, venous thromboembolic complications, deep venous thrombosis, use of allogeneic blood transfusion, estimated blood loss (EBL), and postoperative hemoglobin. Patients who received TXA were compared with controls who did not receive TXA intraoperatively using random-effects models. RESULTS: A total of 508 unique articles were identified, of which 493 underwent full-text review. Ultimately, 6 studies with 381 total patients (190 receiving TXA) were included in the final analysis. All 6 trials were randomized, blinded, and placebo controlled with a TXA administration rate of a 20-mg/kg load followed by a 1-mg/kg/hr infusion. All studies were performed in lower-middle-income countries. There were no reported instances of venous thromboembolism (VTE) in the TXA and non-TXA cohorts. Patients receiving TXA exhibited fewer allogeneic transfusions (21.5% vs 41.6% [OR 0.26, 95% CI 0.09-0.77], p = 0.02) and lower EBL (MD -282.48 mL [95% CI -367.77 to -197.20 mL], p < 0.001) compared with patients who did not receive TXA, and they also had lower rates of perioperative complications (10.7% vs 19.9% [OR 0.47, 95% CI 0.2-0.95], p = 0.04). CONCLUSIONS: Current literature suggests that TXA is not associated with increased risk for VTE when administered during resection of intracranial meningioma. TXA appears to decrease intraoperative blood loss and allogeneic transfusion requirements during meningioma resection and thus may improve the safety of surgical management of this pathology.
