RESUMO

Background: Immigrant groups from Southeast Asia, the Pacific Islands, sub-Saharan Africa, and the Caribbean bear the heaviest burden of chronic hepatitis B and primary liver cancer in the United States. Educational campaigns to increase knowledge about these diseases and their connection are necessary to promote protective health behaviors within these communities, to ultimately reduce the burden of disease, lessen stigma, and eliminate health disparities. Objectives: This project sought to engage groups within highly impacted communities to identify existing gaps in hepatitis B- and liver cancer-related knowledge, in order to inform future health education programming that will aim to reduce stigma and promote liver cancer prevention and early detection behaviors within and across groups. Methods: Fifteen focus groups and two key informant interviews were conducted virtually with participants from Micronesian, Chinese, Hmong, Nigerian, Ghanaian, Vietnamese, Korean, Somali, Ethiopian, Filipino, Haitian, and Francophone West African communities. Qualitative data were analyzed using thematic coding. Results: There are large gaps in knowledge and awareness of hepatitis B and liver cancer, and the link between these two diseases among Asian, Pacific Islander, African and Haitian immigrant communities. This limited knowledge and misinformation, exacerbated by stigma, hinder these groups' utilization of hepatitis B and liver cancer diagnostic and preventative healthcare services. Conclusion: To reduce hepatitis B and liver cancer health disparities within heavily burdened groups, health education needs to be community-informed, culturally sensitive, and actionable. Study results can guide the development of culturally and linguistically appropriate education programs that focus on the link between hepatitis B and liver cancer and the need for vaccination and routine screening, and that are responsive to the knowledge gaps and misperceptions of diverse communities. The results also provide valuable insights for healthcare providers to improve the knowledge gaps of the diverse patient populations that they serve.

RESUMO

BACKGROUND: Pediatric-type diffuse high-grade glioma (pHGG) is the most frequent malignant brain tumor in children and can be subclassified into multiple entities. Fusion genes activating the MET receptor tyrosine kinase often occur in infant-type hemispheric glioma (IHG) but also in other pHGG and are associated with devastating morbidity and mortality. METHODS: To identify new treatment options, we established and characterized two novel orthotopic mouse models harboring distinct MET fusions. These included an immunocompetent, murine allograft model and patient-derived orthotopic xenografts (PDOX) from a MET-fusion IHG patient who failed conventional therapy and targeted therapy with cabozantinib. With these models, we analyzed the efficacy and pharmacokinetic properties of three MET inhibitors, capmatinib, crizotinib and cabozantinib, alone or combined with radiotherapy. RESULTS: Capmatinib showed superior brain pharmacokinetic properties and greater in vitro and in vivo efficacy than cabozantinib or crizotinib in both models. The PDOX models recapitulated the poor efficacy of cabozantinib experienced by the patient. In contrast, capmatinib extended survival and induced long-term progression-free survival when combined with radiotherapy in two complementary mouse models. Capmatinib treatment increased radiation-induced DNA double-strand breaks and delayed their repair. CONCLUSIONS: We comprehensively investigated the combination of MET inhibition and radiotherapy as a novel treatment option for MET-driven pHGG. Our seminal preclinical data package includes pharmacokinetic characterization, recapitulation of clinical outcomes, coinciding results from multiple complementing in vivo studies, and insights into molecular mechanism underlying increased efficacy. Taken together, we demonstrate the groundbreaking efficacy of capmatinib and radiation as a highly promising concept for future clinical trials.

RESUMO

Asian, Pacific Islander, African, and Caribbean communities in the U.S. are heavily impacted by chronic hepatitis B (HBV) and hepatocellular carcinoma (HCC). Educating these groups about the link between the two diseases is imperative to improve screening rates and health outcomes. This study aims to identify and incorporate preferred mediated communication methods into community-specific educational campaigns which emphasize the connection between the conditions, to promote uptake of prevention and management behaviors for HBV and HCC. Fifteen focus groups and two key informant interviews were conducted with Micronesian, Chinese, Hmong, Nigerian, Ghanaian, Vietnamese, Korean, Somali, Ethiopian, Filipino, Haitian, and Francophone West African communities. Data were analyzed using thematic coding and analysis. Findings demonstrate that all communities preferred materials be offered in both English and native languages and requested that materials highlight the connection between HBV and HCC. Delivery channel preferences and messaging themes varied by group. This study provides insight into community-specific preferences for learning about HBV and HCC. The findings can be used to design culturally and linguistically tailored, multi-platform, health education campaigns to facilitate improved HBV screening and vaccination rates and increase knowledge about HCC risk among highly impacted communities in the U.S.

RESUMO

OBJECTIVE: Postpartum hemorrhage is a leading cause of maternal mortality and morbidity around the globe. The novel low-suction vacuum hemorrhage device (VHD) provides an alternative treatment option for cases of postpartum hemorrhage when first-line uterotonic agents fail. This systematic review aims to review current data evaluating the overall efficacy and safety of VHDs in treating postpartum hemorrhage. METHODS: We searched CINAHL Ultimate, Academic Search Premier, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, MEDLINE with Full Text, and PubMed and reference lists of retrieved studies for eligible studies that included outcomes of effectiveness, efficacy, or safety. Two independent reviewers used Covidence.org to screen Titles and Abstracts for 69 studies of which six were included in the analysis. Secondary outcomes measured across studies included time to bleeding control, total device deployment time, and adverse effects. RESULTS: Six nonrandomized trials (N = 1018 participants) included studies conducted in Indonesia, the United States, Switzerland, and Canada. The VHDs were found to have 90% effectiveness in achieving bleeding control across the studies. For most patients, this was achieved in <5 min and required a total device deployment time of 3 h. Reported adverse events were not considered life-threatening, including endometritis in 11 patients and red blood cell transfusions in 38% of patients. CONCLUSION: VHDs have the potential to be used as a rapidly effective means for mechanical intervention of postpartum hemorrhage. The efficacy and safety of VHDs must be further studied at the randomized controlled trial level to determine their clinical usage.

RESUMO

Huntington's disease (HD) is a neurodegenerative genetic disorder caused by an expansion in the CAG repeat tract of the huntingtin (HTT) gene resulting in behavioural, cognitive, and motor defects. Current knowledge of disease pathogenesis remains incomplete, and no disease course-modifying interventions are in clinical use. We have previously reported the development and characterisation of the OVT73 transgenic sheep model of HD. The 73 polyglutamine repeat is somatically stable and therefore likely captures a prodromal phase of the disease with an absence of motor symptomatology even at 5-years of age and no detectable striatal cell loss. To better understand the disease-initiating events we have undertaken a single nuclei transcriptome study of the striatum of an extensively studied cohort of 5-year-old OVT73 HD sheep and age matched wild-type controls. We have identified transcriptional upregulation of genes encoding N-methyl-D-aspartate (NMDA), α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) and kainate receptors in medium spiny neurons, the cell type preferentially lost early in HD. Further, we observed an upregulation of astrocytic glutamate uptake transporters and medium spiny neuron GABAA receptors, which may maintain glutamate homeostasis. Taken together, these observations support the glutamate excitotoxicity hypothesis as an early neurodegeneration cascade-initiating process but the threshold of toxicity may be regulated by several protective mechanisms. Addressing this biochemical defect early may prevent neuronal loss and avoid the more complex secondary consequences precipitated by cell death.

RESUMO

BACKGROUND: People with mild intellectual disabilities (MID) experience more mental health (MH) problems than the general population but often do not receive appropriate primary MH care. Primary MH care is essential in integrative MH care and, therefore, demands high quality. To improve primary MH care for this patient group, account must be taken of the experiences of people with MID. So far, their perspectives have been largely absent from primary MH care research. OBJECTIVES: To explore patients' experiences, needs, and suggestions for improvement regarding primary MH care for people with MID. METHODS: Qualitative study among adults with MID who visited their GP with MH problems in the previous 12 months. Semi-structured interviews were conducted using a guide based on Person-Centred Primary Care Measures. Transcripts were analysed thematically. RESULTS: The 11 interviews that we conducted revealed four themes. The first theme, cumulative vulnerability, describes the vulnerability - instigated by the MID and reinforced by MH problems - experienced on a GP visit. The other themes (needs regarding the GP, needs regarding the network, self-determination) arise from this vulnerability. CONCLUSION: People with both MID and MH problems are extra vulnerable in primary care but desire self-determination regarding their MH care trajectory. This requires investment in a good GP-patient relationship and the organisation of additional support to meet these patients' needs, for which collaborative care with the patient, the patient's network, and other (care) professionals is of utmost importance.


People with mild intellectual disabilities (MID) feel more vulnerable visiting their GP with mental health (MH) problems than with somatic problemsPatients with MH problems report additional needs and expectations regarding their care and support networkGPs face challenges in coordinating care for patients with both MID and MH problems.

RESUMO

BACKGROUND: Prior studies have found that patients with chronic kidney disease (CKD) have worse outcomes following percutaneous coronary intervention (PCI). There are no data about patients with advanced CKD undergoing Impella-supported high-risk PCI. We, therefore, aimed to evaluate angiographic characteristics and clinical outcomes in patients with CKD who received Impella-supported high-risk PCI as part of the catheter-based ventricular assist device PROTECT III study (A Prospective, Multi-Center, Randomized Controlled Trial of the IMPELLA RECOVER LP 2.5 System Versus Intra Aortic Balloon Pump [IABP] in Patients Undergoing Non Emergent High Risk PCI). METHODS: Patients enrolled in the PROTECT III study were analyzed according to their baseline estimated glomerular filtration rate (eGFR). The primary outcome was 90-day major adverse cardiovascular and cerebrovascular events (the composite of all-cause death, myocardial infarction, stroke/transient ischemic attack, and repeat revascularization). RESULTS: Of 1237 enrolled patients, 1052 patients with complete eGFR baseline assessment were evaluated: 586 with eGFR ≥60 mL/min per 1.73 m2, 190 with eGFR ≥45 to <60, 105 with eGFR ≥30 to <45, and 171 with eGFR <30 or on dialysis. Patients with lower eGFR (all groups with eGFR <60) were more frequently females and had a higher prevalence of hypertension, diabetes, anemia, and peripheral artery disease. The baseline Synergy Between PCI With Taxus and Cardiac Surgery score was similar between groups (28.2±12.6 for all groups). Patients with lower eGFR were more likely to have severe coronary calcifications and higher usage of atherectomy. There were no differences in individual PCI-related coronary complications between groups, but the rates of overall PCI complications were less frequent among patients with lower eGFR. Major adverse cardiovascular and cerebrovascular events at 90 days and 1-year mortality were significantly higher among patients with eGFR <30 mL/min per 1.73 m2 or on dialysis. CONCLUSIONS: Patients with advanced CKD undergoing Impella-assisted high-risk PCI tend to have higher baseline comorbidities, severe coronary calcification, and higher atherectomy usage, yet CKD was not associated with a higher rate of immediate PCI-related complications. However, 90-day major adverse cardiovascular and cerebrovascular events and 1-year mortality were significantly higher among patients with eGFR<30 mL/min per 1.73 m2 or on dialysis. Future studies of strategies to improve intermediate and long-term outcomes of these high-risk patients are warranted.

RESUMO

A strategy of complete revascularization (CR) is recommended in patients with acute coronary syndrome (ACS) and multivessel disease (MVD). However, the optimal timing of CR remains equivocal. We searched MEDLINE, Embase, the Cochrane Library, and ClinicalTrials.gov for randomized controlled trials (RCTs) comparing immediate CR (ICR) with staged CR in patients with ACS and MVD. Our primary outcomes were all-cause and cardiovascular mortality. All outcomes were assessed at 3 time points: in-hospital or at 30 days, at 6 months to 1 year, and at >1 year. Data were pooled in RevMan 5.4 using risk ratios as the effect measure. A total of 9 RCTs (7,506 patients) were included in our review. A total of 7 trials enrolled patients with ST-segment elevation myocardial infarction (STEMI), 1 enrolled patients with non-STEMI only, and 1 enrolled patients with all types of ACS. There was no difference between ICR and staged CR regarding all-cause and cardiovascular mortality at any time window. ICR reduced the rate of myocardial infarction and decreased the rate of repeat revascularization at 6 months and beyond. The rates of cerebrovascular events and stent thrombosis were similar between the 2 groups. In conclusion, the present meta-analysis demonstrated a lower rate of myocardial infarction and a reduction in repeat revascularization at and after 6 months with ICR strategy in patients with mainly STEMI and MVD. The 2 groups had no difference in the risk of all-cause and cardiovascular mortality. Further RCTs are needed to provide more definitive conclusions and investigate CR strategies in other ACS.

RESUMO

The number of different methods of reperfusion therapy to treat venous thromboembolism (VTE) has increased substantially. Nevertheless, investigation of data representativeness and device-level use in administrative databases has been limited. Using the National Inpatient Sample (NIS) and the PINC AI Healthcare Database (PHD), all hospital encounters with a diagnosis code of VTE were identified between January 1, 2016 and December 31, 2020. Patient demographics and trends in treatment modalities were evaluated over time. An algorithm was developed to identify specific devices used for VTE treatment in the PHD cohort. A total of 145,870 patients with VTE treated with reperfusion therapy were identified in the NIS (pulmonary embolism [PE] 88,725, isolated deep vein thrombosis [iDVT] 57,145) and 39,311 in the PHD (PE 25,383, iDVT 13,928). Patient demographics were qualitatively similar in the NIS and PHD. Over time, there was a significant increase in the use of mechanical thrombectomy in the PE and iDVT populations (p <0.05 in both databases), with catheter-directed thrombolysis use plateauing in PE (p = 0.83 and p = 0.14 in NIS and PHD, respectively) and significantly decreasing for the iDVT population (p <0.05 in both databases). In the PHD cohort, specific reperfusion devices were identified in 14,105 patients (PE 9,098, iDVT 5,007). In conclusion, the use of mechanical thrombectomy for the treatment of VTE has increased over time, whereas the rates of catheter-directed thrombolysis therapy have remained stagnant or decreased. Further research is needed to understand the uptake of these treatment modalities and the unique abilities of the PHD to study specific device therapy in the VTE population.

RESUMO

Aging is the gradual decline in physical and physiological functioning leading to increased susceptibility to stressors and chronic illnesses, including cardiovascular disease. With an aging global population, in which 1 in 6 individuals will be older than 60 years by 2030, interventional cardiologists are increasingly involved in providing complex care for older individuals. Although procedural aspects remain their main clinical focus, interventionalists frequently encounter age-associated risks that influence eligibility for invasive care, decision making during the intervention, procedural adverse events, and long-term management decisions. The unprecedented growth in transcatheter interventions, especially for structural heart diseases at extremes of age, have pushed age-related risks and implications for cardiovascular care to the forefront. In this JACC state-of-the-art review, the authors provide a comprehensive overview of the aging process as it relates to cardiovascular interventions, with special emphasis on the difference between chronological and biological aging. The authors also address key considerations to improve health outcomes for older patients during and after their invasive cardiovascular care. The role of "gerotherapeutics" in interventional cardiology, technological innovation in measuring biological aging, and the integration of patient-centered outcomes in the older adult population are also discussed.

RESUMO

OBJECTIVE: To analyze the cost-effectiveness of transcatheter aortic valve implantation (TAVI) using the SAPIEN 3 (Edwards Lifesciences, Irvine, CA) compared to surgical aortic valve replacement (SAVR) in low- and intermediate-risk patients from a Japanese public healthcare payer perspective. METHODS: A Markov model cost-effectiveness analysis was developed. Clinical and utility data were extracted from a systematic literature review. Cost inputs were obtained from analysis of the Medical Data Vision claims database and supplemented with a targeted literature search. The robustness of the results was assessed using sensitivity analyses. Scenario analyses were performed to determine the impact of lower mean age (77.5 years) and the effect of two different long-term mortality hazard ratios (TAVI versus SAVR: 0.9-1.09) on both risk-level populations. This analysis was conducted according to the guidelines for cost-effectiveness evaluation in Japan from Core 2 Health. RESULTS: In intermediate-risk patients, TAVI was a dominant procedure (TAVI had lower cost and higher effectiveness). In low-risk patients, the incremental cost effectiveness ratio (ICER) for TAVI was ¥750,417/quality-adjusted-life-years (QALY), which was below the cost-effectiveness threshold of ¥5 million/QALY. The ICER for TAVI was robust to all tested sensitivity and scenario analyses. CONCLUSIONS: TAVI was dominant and cost-effective compared to SAVR in intermediate- and low-risk patients, respectively. These results suggest that TAVI can provide meaningful value to Japanese patients relative to SAVR, at a reasonable incremental cost for patients at low surgical risk and potentially resulting in cost-savings in patients at intermediate surgical risk.


Aortic Stenosis (AS) is the most common valvular heart disease in Japan, and, if left untreated, severe symptomatic AS (sSAS) is associated with a dramatic increase in mortality and morbidity. Transcatheter Aortic Valve Implantation (TAVI) is a minimally invasive treatment option for replacing the aortic valve in patients with sSAS and has been associated with similar or better outcomes compared to Surgical Aortic Valve Replacement (SAVR), which involves open-heart surgical replacement of the aortic valve. The objective of this study was to compare the costs and health outcomes associated with TAVI compared to SAVR in Japanese patients deemed low- or intermediate-risk for surgery. Despite the expanding use of TAVI in Japan, a cost-effectiveness analysis (CEA) does not exist that evaluates the economics of TAVI with the current generation SAPIEN 3 implant in patients with low- and intermediate-risk from a public perspective. Our study suggests that TAVI represents strong value for money among low- and intermediate-risk patients in Japan: compared to SAVR, TAVI is associated with better clinical outcomes and quality of life for patients, at a reasonable additional cost for low-risk patients and at a lower cost for intermediate-risk patients.

RESUMO

BACKGROUND: Symptomatic patients with severe aortic stenosis (AS) at high risk for surgical aortic valve replacement (SAVR) sustain comparable improvements in health status over 5 years after transcatheter aortic valve replacement (TAVR) or SAVR. Whether a similar long-term benefit is observed among intermediate-risk AS patients is unknown. OBJECTIVES: The purpose of this study was to assess health status outcomes through 5 years in intermediate risk patients treated with a self-expanding TAVR prosthesis or SAVR using data from the SURTAVI (Surgical Replacement and Transcatheter Aortic Valve Implantation) trial. METHODS: Intermediate-risk patients randomized to transfemoral TAVR or SAVR in the SURTAVI trial had disease-specific health status assessed at baseline, 30 days, and annually to 5 years using the Kansas City Cardiomyopathy Questionnaire (KCCQ). Health status was compared between groups using fixed effects repeated measures modelling. RESULTS: Of the 1,584 patients (TAVR, n = 805; SAVR, n = 779) included in the analysis, health status improved more rapidly after TAVR compared with SAVR. However, by 1 year, both groups experienced large health status benefits (mean change in KCCQ-Overall Summary Score (KCCQ-OS) from baseline: TAVR: 20.5 ± 22.4; SAVR: 20.5 ± 22.2). This benefit was sustained, albeit modestly attenuated, at 5 years (mean change in KCCQ-OS from baseline: TAVR: 15.4 ± 25.1; SAVR: 14.3 ± 24.2). There were no significant differences in health status between the cohorts at 1 year or beyond. Similar findings were observed in the KCCQ subscales, although a substantial attenuation of benefit was noted in the physical limitation subscale over time in both groups. CONCLUSIONS: In intermediate-risk AS patients, both transfemoral TAVR and SAVR resulted in comparable and durable health status benefits to 5 years. Further research is necessary to elucidate the mechanisms for the small decline in health status noted at 5 years compared with 1 year in both groups.

RESUMO

INTRODUCTION: Neoadjuvant therapy has become a standard treatment for patients with stage II/III HER2 positive and triple negative breast cancer, and in well-selected patients with locally advanced and borderline resectable high risk, luminal B breast cancer. Side effects of neoadjuvant therapy, such as fatigue, cardiotoxicity, neurotoxicity, anxiety, insomnia, vasomotor symptoms, gastrointestinal disturbance as well as a raft of immune-related adverse events, may impact treatment tolerance, long-term outcomes, and quality of life. Providing early supportive care prior to surgery (typically termed 'prehabilitation') may mitigate these side effects and improve quality of life.During our codesign of the intervention, consumers and healthcare professionals expressed desire for a programme that 'packaged' care, was easy to access, and was embedded in their care pathway. We hypothesise that a multimodal supportive care programme including exercise and complementary therapies, underpinned by behavioural change theory will improve self-efficacy, quality of life, readiness for surgery and any additional treatment for women with breast cancer. We seek to explore cardiometabolic, residual cancer burden and surgical outcomes, along with chemotherapy completion (relative dose intensity). This article describes the protocol for a feasibility study of a multimodal prehabilitation programme. METHODS AND ANALYSIS: This is a prospective, mixed-method, feasibility study of a multi-modal programme in a hospital setting for 20-30 women with breast cancer receiving neoadjuvant therapy. Primary outcomes are recruitment rate, retention rate, adherence and acceptability. Secondary outcomes include patient reported outcome measures (PROMs), surgical outcomes, length of stay, satisfaction with surgery, chemotherapy completion rates, changes in metabolic markers and adverse events. Interviews and focus groups to understand the experience with prehabilitation and different factors that may affect feasibility of the intervention . The output of this study will be a codesigned, evidence-informed intervention assessed for feasibility and acceptability by women with breast cancer and the healthcare professionals that care for them. ETHICS AND DISSEMINATION: The study received ethics approval from the St Vincents Hospital HREC (HREC/2021/ETH12198). Trial results will be communicated to participants, healthcare professionals, and the public via publication and conferences. TRIAL REGISTRATION NUMBER: ACTRN12622000584730.

RESUMO

Dengue is a global public health threat, with about half of the world's population at risk of contracting this mosquito-borne viral disease. Climate change, urbanization, and global travel accelerate the spread of dengue virus (DENV) to new areas, including southern parts of Europe and the US. Currently, no dengue-specific small-molecule antiviral for prophylaxis or treatment is available. Here, we report the discovery of JNJ-1802 as a potent, pan-serotype DENV inhibitor (EC50's ranging from 0.057 to 11 nM against the four DENV serotypes). The observed oral bioavailability of JNJ-1802 across preclinical species, its low clearance in human hepatocytes, the absence of major in vitro pharmacology safety alerts, and a dose-proportional increase in efficacy against DENV-2 infection in mice were all supportive of its selection as a development candidate against dengue. JNJ-1802 is being progressed in clinical studies for the prevention or treatment of dengue.

RESUMO

Background: Physical activity (PA) levels of people with coronary heart disease are low in the first 30 days after percutaneous coronary intervention (PCI), increasing the risk of recurrent cardiac events. Following PCI, PA counseling delivered by a physiotherapist before discharge may increase the PA levels of patients. Preliminary work is required to determine the effects of the counseling session compared to usual care. Objectives: To investigate the feasibility and potential efficacy of a brief physiotherapist-led PA counseling session immediately after an elective PCI compared to usual care for improved PA early post-PCI. Methods: Using concealed allocation and blinded assessments, eligible participants (n = 30) were randomized to a physiotherapist-led PA counseling session (30 min) or usual care (nurse-led PA advice < 5 min). The primary outcome was daily minutes of moderate-to-vigorous PA (accelerometry; 3 weeks). Secondary outcomes included cardiac rehabilitation intention, anxiety and depression levels (Hospital Anxiety and Depression Scale), and quality-of-life (MacNew questionnaire). Recruitment, retention, and attrition were assessed for feasibility. Semistructured interviews were conducted with 13 participants to determine intervention acceptability, and barriers and enablers to PA. Results: Between and within-group comparisons were not significant in intention-to-treat analyses. All feasibility criteria were met except for retention and attrition of participants. At 3 weeks, only 25% of participants were planning to attend cardiac rehabilitation, with no between-group differences. Increased PA at 3 weeks was associated with participants that were younger, without other chronic disease,s and more active immediately following discharge. Interviews revealed personal, environmental, and program-based themes for barriers and enablers to PA. Conclusions: A physiotherapist-led PA counseling session may not improve PA levels early post-elective PCI compared to very brief PA advice delivered by nurses. A larger multicentre randomized controlled trial is feasible with minor modifications to participant follow-up. Further research is required.

RESUMO

OBJECTIVE: Hypothyroidism is a common endocrine condition usually managed with levothyroxine (LT4). However, controversy remains around the use of liothyronine (LT3). We aimed to investigate the practices of Australian endocrinologists when managing patients with hypothyroidism, their use of LT3 + LT4 combination therapy and use of thyroid hormones in euthyroid patients. DESIGN AND PARTICIPANTS: Members of the Endocrine Society of Australia (ESA) were invited to participate in an online questionnaire. MEASUREMENTS: We analysed questionnaires that had complete demographic data. RESULTS: Eighty-seven questionnaires fulfilled the criteria. LT4 was used as first line treatment for hypothyroidism by all respondents. Only 45% reported that their patients were dispensed the brand of LT4 that they recommend. LT3 (alone or in combination) was prescribed by 44% in their clinical practice. Although 49% of respondents would consider LT3 + LT4 in patients with normal TSH who had ongoing symptoms of hypothyroidism, the inability of LT4 to restore normal physiology was ranked the least likely explanation for persistent symptoms and only 32% would consider it for themselves if they were diagnosed with hypothyroidism. The majority (55%), in accordance with evidence, would not prescribe thyroid hormone to euthyroid individuals but 39% would consider use in euthyroid female infertility with high levels of thyroid antibodies and 11% in euthyroid patients with a simple goitre growing over time. LT4 use in pregnancy was variable among members. CONCLUSIONS: Australian endocrinologists mostly follow international guidelines when prescribing thyroid hormone therapy and many prescribe combination LT3 and LT4 therapy, particularly for patients who remain symptomatic on LT4 monotherapy. Prescribing practices are largely similar to other countries who have completed similar questionnaires.

RESUMO

Orthotic wrist supports will be beneficial for people with muscular weakness to keep their hand in a neutral rest position and prevent potential wrist contractures. Compensating the weight of the hands is complex since the level of support depends on both wrist and forearm orientations. To explore simplified approaches, two different weight compensation strategies (constant and linear) were compared to the theoretical ideal sinusoidal profile and no compensation in eight healthy subjects using a mechanical wrist support system. All three compensation strategies showed a significant reduction of 47-53% surface electromyography activity in the anti-gravity m. extensor carpi radialis. However, for the higher palmar flexion region, a significant increase of 44-61% in the m. flexor carpi radialis was found for all compensation strategies. No significant differences were observed between the various compensation strategies. Two conclusions can be drawn: (1) a simplified torque profile (e.g., constant or linear) for weight compensation can be considered as equally effective as the theoretically ideal sinusoidal profile and (2) even the theoretically ideal profile provides no perfect support as other factors than weight, such as passive joint impedance, most likely influence the required compensation torque for the wrist joint.

RESUMO

BACKGROUND: Zuranolone, an oral version of allopregnanolone and neurosteroid, is a novel drug for the treatment of major depressive disorder (MDD) and postpartum depression (PPD). AIM: The purpose of this systematic review and meta-analysis was to assess the efficacy of zuranolone in the treatment of MDD and PPD. METHOD: A systematic search was conducted using EBSCOhost to simultaneously search Academic Search Premier, APA PsycArticles, APA PsycInfo, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, CINAHL Ultimate, and MEDLINE with Full Text. Two independent reviewers screened the articles and completed a full-text review using Covidence. The quality of each study was assessed using the Cochrane Risk of Bias tool for randomized trials (RoB 2). A meta-analysis was then conducted using Review Manager (RevMan v5.4) software. RESULTS: The initial search yielded 127 results, with 6 articles fitting our inclusion and exclusion criteria. All 6 studies, comprising 1707 participants, had an overall low risk of bias. There was a significant decrease in HAM-D scores for MDD at 15 days versus placebo (MD - 2.40, 95% CI - 3.07 to - 1.63; p < .001). When pooling data for PDD, there was an overall significant decrease in HAM-D scores at 15 days versus placebo (MD - 4.06, 95% CI - 4.25 to - 3.87; p < .001). CONCLUSION: The results suggest that zuranolone can improve symptoms of PPD at 15 days; however, results were not clinically significant for MDD. Future research is needed to evaluate the long-term efficacy of zuranolone in PPD and the treatment efficacy in MDD.
