RESUMO

Surgical management of basal cell carcinoma (BCC) typically involves surgical excision with post-operative margin assessment using the bread-loafing technique; or gold-standard Mohs micrographic surgery (MMS), where margins are iteratively examined for residual cancer after tumour removal, with additional excisions performed upon detecting residual tumour at margins. There is limited sampling of resection margins with bread loafing, with detection of positive margins 44% of the time using 2 mm intervals. To resolve this, we have developed three-dimensional (3D) Tissue Imaging for: (1) complete examination of cancer margins and (2) detection of tumour proximity to nerves and blood vessels. 3D Tissue optical clearing with a light sheet imaging protocol was developed for margin assessment in two datasets assessed by two independent evaluators: (1) 48 samples from 29 patients with varied BCC subtypes, sizes and pigmentation levels; (2) 32 samples with matching Mohs' surgeon reading of tumour margins using two-dimensional haematoxylin & eosin-stained sections. The 3D Tissue Imaging protocol permits a complete examination of deeper and peripheral margins. Two independent evaluators achieved negative predictive values of 92.3% and 88.24% with 3D Tissue Imaging. Images obtained from 3D Tissue Imaging recapitulates histological features of BCC, such as nuclear crowding, palisading and retraction clefting and provides a 3D context for recognising normal skin adnexal structures. Concurrent immunofluorescence labelling of nerves and blood vessels allows visualisation of structures closer to tumour-positive regions, which may have a higher risk for neural and vascular infiltration. Together, this method provides more information in a 3D spatial context, enabling better cancer management by clinicians.

RESUMO

OBJECTIVES: Previous systematic reviews show a clear relationship between frailty and depression, however the association with anxiety is much less frequently explored. Previous single studies indicate evidence is mixed. We completed a systematic review and meta-analysis to identify the relationship between frailty and anxiety. METHODS: We searched five electronic databases for observational studies in older people in community, care home and outpatient settings with any/no health conditions that measured the association between anxiety and frailty using validated measures. Studies were screened by one reviewer with 10% checked by a second reviewer. The Mixed Methods Appraisal Tool was used to assess study quality. We used meta-analysis to aggregate study findings, with subgroup analyses to explore heterogeneity. RESULTS: Out of 1272 references, a total of 20 cross-sectional and 1 longitudinal studies were eligible. Older adults with frailty were substantially more likely to display anxiety symptoms than robust populations, across both dichotomous and continuous data sets (n = 10, OR = 3.48, 95% CI: 2.08, 5.81, p < 0.0001, I2  = 94%; N = 5, SMD = 3.13, 95% CI: 1.06, 5.21, I2  = 98%). Similarly, pre-frail older adults were more likely to have anxiety symptoms than robust older adults but to a lesser extent (N = 6, OR = 1.95, 95% CI: 1.41, 2.71, I2  = 63%; N = 3, SMD = 1.70, 95% CI: 0.01, 3.38, I2  = 98%). CONCLUSIONS: There is a clear association between pre-frailty/frailty and anxiety in older adults. However, data are heterogeneous and primarily from cross-sectional studies so causality cannot be determined. Future research should evaluate the effectiveness of anxiety screening and treatments in frail older adults.

RESUMO

The development and mechanistic investigation of a nickel-catalyzed sulfonylation of aryl bromides is disclosed. The reaction proceeds in good yields for a variety of substrates and utilizes an inexpensive, stench-free, inorganic sulfur salt (K2 S2 O5 ) as a uniquely effective SO2 surrogate. The active oxidative addition complex was synthesized, isolated, and fully characterized by a combination of NMR spectroscopy and X-ray crystallography analysis. The use of the isolated oxidative addition complex in both stoichiometric and catalytic reactions revealed that SO2 insertion occurs via dissolved SO2 , likely released upon thermal decomposition of K2 S2 O5 . Key to the success of the reaction is the role of K2 S2 O5 as a reservoir of SO2 that is slowly released, thus preventing catalyst poisoning.

RESUMO

BACKGROUND: Radiotherapy before mastectomy and autologous free-flap breast reconstruction can avoid adverse radiation effects on healthy donor tissues and delays to adjuvant radiotherapy. However, evidence for this treatment sequence is sparse. We aimed to explore the feasibility of preoperative radiotherapy followed by skin-sparing mastectomy and deep inferior epigastric perforator (DIEP) flap reconstruction in patients with breast cancer requiring mastectomy. METHODS: We conducted a prospective, non-randomised, feasibility study at two National Health Service trusts in the UK. Eligible patients were women aged older than 18 years with a laboratory diagnosis of primary breast cancer requiring mastectomy and post-mastectomy radiotherapy, who were suitable for DIEP flap reconstruction. Preoperative radiotherapy started 3-4 weeks after neoadjuvant chemotherapy and was delivered to the breast, plus regional nodes as required, at 40 Gy in 15 fractions (over 3 weeks) or 42·72 Gy in 16 fractions (over 3·2 weeks). Adverse skin radiation toxicity was assessed preoperatively using the Radiation Therapy Oncology Group toxicity grading system. Skin-sparing mastectomy and DIEP flap reconstruction were planned for 2-6 weeks after completion of preoperative radiotherapy. The primary endpoint was the proportion of open breast wounds greater than 1 cm width requiring a dressing at 4 weeks after surgery, assessed in all participants. This study is registered with ClinicalTrials.gov, NCT02771938, and is closed to recruitment. FINDINGS: Between Jan 25, 2016, and Dec 11, 2017, 33 patients were enrolled. At 4 weeks after surgery, four (12·1%, 95% CI 3·4-28·2) of 33 patients had an open breast wound greater than 1 cm. One (3%) patient had confluent moist desquamation (grade 3). There were no serious treatment-related adverse events and no treatment-related deaths. INTERPRETATION: Preoperative radiotherapy followed by skin-sparing mastectomy and immediate DIEP flap reconstruction is feasible and technically safe, with rates of breast open wounds similar to those reported with post-mastectomy radiotherapy. A randomised trial comparing preoperative radiotherapy with post-mastectomy radiotherapy is required to precisely determine and compare surgical, oncological, and breast reconstruction outcomes, including quality of life.

RESUMO

Cancer is a disease that evolves continuously with unpredictable outcomes. Although conventional chemotherapy can display significant antitumor effects, the lack of specificity and poor bioavailability remain major concerns in cancer therapy. Moreover, with the advent of novel anti-cancer gene therapies, there is an urgent need for drug delivery vectors capable of bypassing cellular barriers and efficiently transferring therapeutic cargo to recipient cells. A number of drug delivery systems have been proposed to overcome these limitations, but their successful clinical translation has been hampered by the onset of unexpected side effects and associated toxicities. The application of extracellular vesicles (EVs), a class of naturally released, cell-derived particles, as drug delivery vectors presents a breakthrough in nanomedicine, taking into account their biocompatibility and natural role in intercellular communication. Combining the advantageous intrinsic properties of EVs with surface functionalization and the encapsulation of drugs allows for a new class of engineered EVs that serve as effective therapeutic carriers. Here, we describe the various successful approaches involving the application of engineered EVs as bio-derived drug delivery vectors in cancer therapy. The latest and most effective strategies of engineering EVs to improve drug loading, stealth properties and tumour targeting capabilities of EVs are debated. Finally, current obstacles and future perspectives of smart engineered EVs are discussed.

RESUMO

BACKGROUND: Chyle leak after axillary surgery is a rare complication that lacks consensus and management guidelines. This study aimed to present the experiences of two centers in chyle leak management after axillary node clearance for breast cancer. Furthermore the authors provide a review of its pathophysiology and clinical diagnostic methods. They compare approaches for management of the axilla with those for other locations. METHODS: A multicentre case series descriptive analysis of chyle leak after breast cancer axillary node clearance between 1 January 2013 and 31 May 2020 was performed. RESULTS: The center in the United Kingdom and the center in Italy performed 655 and 4969 axillary node clearances, respectively. Four patients experienced chyle leaks. All the leaks had left-sided surgery (3 patients had level 3 clearances with mastectomy and implant-based breast reconstructions; 1 patient had level 2 clearance with therapeutic mammoplasty). All the leaks appeared within 3 days after surgery. Leak duration was between 11 and 29 days. The maximum daily output was 600 mL. All the leaks were treated conservatively with nutritional team support together with close drainage monitoring. The management strategy included a low-fat diet, a high-protein diet, total parenteral nutrition, and medium chain triglyceride supplements, as well as other elements. No negative effects on oncoplastic and reconstructive breast surgery wound-healing and no delays in adjuvant treatment were observed. CONCLUSION: The incidence of chyle leak after breast cancer axillary node clearance was 0.07%. Early diagnosis and close monitoring together with conservative management involving nutritional team support can result in successful treatment of chyle leak without negative sequalae of breast cancer oncologic treatment.

RESUMO

Although the crystal structures of small-molecule compounds are often determined from single-crystal X-ray diffraction (scXRD), recent advances in three-dimensional electron diffraction (3DED) and crystal structure prediction (CSP) methods promise to expand the structure elucidation toolbox available to the crystallographer. Herein, a comparative assessment of scXRD, 3DED, and CSP in combination with powder X-ray diffraction is carried out on two former drug candidate compounds and a multicomponent crystal of a key building block in the synthesis of gefapixant citrate.

RESUMO

BACKGROUND: Intimate partner violence (IPV) against women is prevalent and strongly associated with mental health problems. Women experiencing IPV attend health services frequently for mental health problems. The World Health Organization recommends that women who have experienced IPV and have a mental health diagnosis should receive evidence-based mental health treatments. However, it is not known if psychological therapies work for women in the context of IPV and whether they cause harm. OBJECTIVES: To assess the effectiveness of psychological therapies for women who experience IPV on the primary outcomes of depression, self-efficacy and an indicator of harm (dropouts) at six- to 12-months' follow-up, and on secondary outcomes of other mental health symptoms, anxiety, quality of life, re-exposure to IPV, safety planning and behaviours, use of healthcare and IPV services, and social support. SEARCH METHODS: We searched the Cochrane Common Mental Disorders Controlled Trials Register (CCMDCTR), CENTRAL, MEDLINE, Embase, CINAHL, PsycINFO, and three other databases, to the end of October 2019. We also searched international trials registries to identify unpublished or ongoing trials and handsearched selected journals, reference lists of included trials and grey literature. SELECTION CRITERIA: We included randomised controlled trials (RCTs), quasi-RCTs, cluster-RCTs and cross-over trials of psychological therapies with women aged 16 years and older who self-reported recent or lifetime experience of IPV. We included trials if women also experienced co-existing mental health diagnoses or substance abuse issues, or both. Psychological therapies included a wide range of interventions that targeted cognition, motivation and behaviour compared with usual care, no treatment, delayed or minimal interventions. We classified psychological therapies according to Cochrane Common Mental Disorders's psychological therapies list. DATA COLLECTION AND ANALYSIS: Two review authors extracted data and undertook 'Risk of Bias' assessment. Treatment effects were compared between experimental and comparator interventions at short-term (up to six months post-baseline), medium-term (six to under 12 months, primary outcome time point), and long-term follow-up (12 months and above). We used standardised mean difference (SMD) for continuous and odds ratio (OR) for dichotomous outcomes, and used random-effects meta-analysis, due to high heterogeneity across trials. MAIN RESULTS: We included 33 psychological trials involving 5517 women randomly assigned to experimental (2798 women, 51%) and comparator interventions (2719 women, 49%). Psychological therapies included 11 integrative therapies, nine humanistic therapies, six cognitive behavioural therapy, four third-wave cognitive behavioural therapies and three other psychologically-orientated interventions. There were no trials classified as psychodynamic therapies. Most trials were from high-income countries (19 in USA, three in Iran, two each in Australia and Greece, and one trial each in China, India, Kenya, Nigeria, Pakistan, Spain and UK), among women recruited from healthcare, community, shelter or refuge settings, or a combination of any or all of these. Psychological therapies were mostly delivered face-to-face (28 trials), but varied by length of treatment (two to 50 sessions) and staff delivering therapies (social workers, nurses, psychologists, community health workers, family doctors, researchers). The average sample size was 82 women (14 to 479), aged 37 years on average, and 66% were unemployed. Half of the women were married or living with a partner and just over half of the participants had experienced IPV in the last 12 months (17 trials), 6% in the past two years (two trials) and 42% during their lifetime (14 trials). Whilst 20 trials (61%) described reliable low-risk random-sampling strategies, only 12 trials (36%) described reliable procedures to conceal the allocation of participant status. While 19 trials measured women's depression, only four trials measured depression as a continuous outcome at medium-term follow-up. These showed a probable beneficial effect of psychological therapies in reducing depression (SMD -0.24, 95% CI -0.47 to -0.01; four trials, 600 women; moderate-certainty evidence). However, for self-efficacy, there may be no evidence of a difference between groups (SMD -0.12, 95% CI -0.33 to 0.09; one trial with medium-term follow-up data, 346 women; low-certainty evidence). Further, there may be no difference between the number of women who dropped out from the experimental or comparator intervention groups, an indicator of no harm (OR 1.04, 95% CI 0.75 to 1.44; five trials with medium-term follow-up data, 840 women; low-certainty evidence). Although no trials reported adverse events from psychological therapies or participation in the trial, only one trial measured harm outcomes using a validated scale. For secondary outcomes, trials measured anxiety only at short-term follow-up, showing that psychological therapies may reduce anxiety symptoms (SMD -0.96, 95% CI -1.29 to -0.63; four trials, 158 women; low-certainty evidence). However, within medium-term follow-up, low-certainty evidence revealed that there may be no evidence between groups for the outcomes safety planning (SMD 0.04, 95% CI -0.18 to 0.25; one trial, 337 women), post-traumatic stress disorder (SMD -0.24, 95% CI -0.54 to 0.06; four trials, 484 women) or re-exposure to any form of IPV (SMD 0.03, 95% CI -0.14 to 0.2; two trials, 547 women). AUTHORS' CONCLUSIONS: There is evidence that for women who experience IPV, psychological therapies probably reduce depression and may reduce anxiety. However, we are uncertain whether psychological therapies improve other outcomes (self-efficacy, post-traumatic stress disorder, re-exposure to IPV, safety planning) and there are limited data on harm. Thus, while psychological therapies probably improve emotional health, it is unclear if women's ongoing needs for safety, support and holistic healing from complex trauma are addressed by this approach. There is a need for more interventions focused on trauma approaches and more rigorous trials (with consistent outcomes at similar follow-up time points), as we were unable to synthesise much of the research.

RESUMO

X-ray powder diffraction and crystal structure prediction (CSP) algorithms were used in synergy to establish the crystal structure of the eighth polymorph of 5-methyl-2-[(2-nitrophenyl)amino]-3-thiophenecarbonitrile (ROY), form R05. R05 crystallizes in the monoclinic space group P21 with lattice parameters a = 11.479(4) Å, b = 11.030(1) Å, c = 10.840(6) Å, ß = 118.23(1)°. This is both the first acentric ROY polymorph, and the first with Z' > 1. The torsion angles defined by the S-C-N-C atom sequence of each molecule in the asymmetric unit (R05-1 and R05-2) are 44.9° and -34.0°. These values are between those previously determined for the red and orange forms of ROY. The crystal packing and intermolecular interactions in R05 are explained herein through Hirshfeld surface analysis and an updated energy stability ranking is determined using computational methods. Although the application of CSP was critical to the structure solution of R05, energy stability rankings determined using a series of DFT van der Waals (vdW)-inclusive models substantially differ from experiment, indicating that ROY polymorphism continues to be a challenge for CSP.

RESUMO

Accurate polarimetric measurements of the optical activity of crystals along low symmetry directions are facilitated by isotropic points, frequencies where dispersion curves of eigenrays cross and the linear birefringence disappears. We report here the optical properties and structure of achiral, uniaxial (point group D2d ) potassium trihydrogen di-(cis-4-cyclohexene-1,2-dicarboxylate) dihydrate, whose isotropic point was previously detected (S. A. Kim, C. Grieswatch, H. Küppers, Zeit. Krist. 1993; 208:219-222) and exploited for a singular measurement of optical activity normal to the optic axis. The crystal structure associated with the aforementioned study was never published. We report it here, confirming the space group assignment I 4¯c2, along with the frequency dependence of the fundamental optical properties and the constitutive tensors by fitting optical dispersion relations to measured Mueller matrix spectra. k-Space maps of circular birefringence and of the Mueller matrix near the isotropic wavelength are measured and simulated. The signs of optical rotation are correlated with the absolute crystallographic directions.

RESUMO

Circulating tumour DNA (ctDNA) is an attractive tool in cancer research, offering many advantages over tissue samples obtained using traditional biopsy methods. There has been increasing interest in its application to muscle-invasive bladder cancer (MIBC), which is recognised to be a heterogeneous disease with overall poor prognosis. Using a range of platforms, studies have shown that ctDNA is detectable in MIBC and may be a useful biomarker in monitoring disease status and guiding treatment decisions in MIBC patients. Currently, with no such predictive or prognostic biomarkers in clinical practice to guide treatment strategy, there is a real unmet need for a personalised medicine approach in MIBC, and ctDNA offers an exciting avenue through which to pursue this goal. In this article, we present an overview of work to date on ctDNA in MIBC, and discuss the inherent challenges present as well as the potential future clinical applications.

RESUMO

AIMS: To evaluate Patient Reported Outcome Measures (PROMs) and surgical outcomes in patients undergoing Chest Wall Perforator Flaps (CWPFs). METHODS: This was an observational single cohort study using an audit approach and a survey instrument. 84 patients who had undergone CWPFs in the last 5 years at the Department of Breast Surgery, City Hospital Birmingham, were identified from a pre-existing database. Surgical outcomes were recorded. Patients were contacted telephonically or in person at the time of follow-up and were asked to fill up a PROMs questionnaire. RESULTS: Out of 84 patients, 58 patients chose to respond. The average age of the patients was 51.3 years (±8.2 years). The average follow-up was 15.4 months (±9.9 months). The most common histological subtype was Infiltrating ductal carcinoma (IDC)-Not otherwise specified 34/58 (58.6%). Majority of the patients had T2 cancers-28/58 (48.3%). 26/58 (44.8%) were node negative. Eight patients (13.7%) had post-operative complications. No patient had total/partial flap loss. Nine patients (15.5%) had margin re-excision. One patient developed distant metastasis while 1 patient developed a second primary. Fifty-one patients (88%) were either satisfied or very satisfied with the post-operative appearance of the breasts. Thirty-six patients (62%) had no/little persistent pain or tenderness post-surgery. Eighty-six per cent (38/44) of the patients undergoing Lateral Intercostal Artery Perforator (LICAP) Flap and 16/18 (89%) of patients undergoing Anterior Intercostal Artery Perforator (AICAP) flap had no/little difficulty in carrying out normal activities at follow up. CONCLUSION: CWPFs are associated with a low complication rate and a high patient satisfaction rate.

RESUMO

OBJECTIVES: Chinese herbal medicine (CHM) has been shown to be effective in autoimmune rheumatic diseases, but harmful herb-drug interactions might be inherent. We aim to review the evidence regarding herb-drug interactions between immunosuppressive drugs used in autoimmune rheumatic diseases and CHM. METHODS: We searched PubMed, EMBASE and CINAHL from inception till 30 April 2023 using keywords that encompassed 'herb-drug interactions', 'herbs' and 'immunosuppressants'. Articles were included if they contained reports about interactions between immunosuppressive drugs used in the treatment of rheumatic diseases with CHM. Level of evidence for each pair of interaction was graded using the algorithm developed by Colalto. RESULTS: A total of 65 articles and 44 unique pairs of interactions were identified. HDIs were reported for cyclophosphamide, cyclosporine, tacrolimus, methotrexate, mycophenolic acid, glucocorticoids, sulfasalazine, tofacitinib and biologic disease-modifying antirheumatic drugs. Among these, cyclosporine (n = 27, 41.5%) and tacrolimus (n = 19, 29.2%) had the highest number of documented interactions. Hypericum perforatum had the highest level of evidence of interaction with cyclosporine and tacrolimus. Consumption reduced the bioavailability and therapeutic effects of the drugs. Schisandra sphenanthera had the highest level of evidence of interaction with tacrolimus and increased the bioavailability of the drug. Majority of the articles were animal studies. CONCLUSION: Overall level of evidence for the included studies were low, though interactions between cyclosporine, tacrolimus, Hypericum perforatum and Schisandra sphenanthera were the most and well-documented. Healthcare professionals should actively enquire about the concurrent use of CHM in patients, especially when drugs with a narrow therapeutic index are consumed.

RESUMO

Disorder is a common feature of molecular crystals that complicates determination of structures and can potentially affect electric and mechanical properties. Suppression of disorder is observed in otherwise severely disordered benzamide and thiobenzamide crystals by substituting hydrogen with fluorine in the ortho-position of the phenyl ring. Fluorine occupancies of 20-30% are sufficient to suppress disorder without changing the packing motif. Crystal structure prediction calculations reveal a much denser lattice energy landscape for benzamide compared to 2-fluorobenzamide, suggesting that fluorine substitution makes disorder less likely.

RESUMO

INTRODUCTION: Vascular diseases, such as stroke and heart failure (HF), are associated with cognitive decline. Vascular cognitive impairment (CI) is commonly found in patients who had a stroke and with HF, ranging from mild CI to dementia. Early detection of CI is crucial for effective management and rehabilitation. This study aimed to develop the VasCog Screen test, a screening tool to detect CI in patients who had a stroke and with HF. METHOD: 427 patients who had a stroke and with HF were assessed using cognitive measures including Mini-Mental State Examination (MMSE), Montreal Cognitive Assessment (MoCA) and a formal neuropsychological battery. The short-MoCA was derived and combined with Symbol Digit Modalities Test (SDMT) to create the VasCog Screen. The discriminatory ability of different tests for CI was compared, establishing optimal cut-off points. Variants of short-MoCA including the SDMT were also evaluated. RESULTS: Similar prevalence rates of CI were found in stroke and HF cohorts. The most prevalent neuropsychological impairment was visuomotor speed, followed by visual memory and visuoconstruction. More than half of the patients were found to have CI. The VasCog Screen outperformed MMSE, MoCA and short-MoCA in detecting CI. The addition of SDMT to variants of the short-MoCA increased diagnostic accuracy. CONCLUSION: The VasCog Screen test offers a cognitive screening tool, which is sensitive to cognitive deficits characteristically found in patients who had a stroke and with HF. It was found to have good sensitivity, specificity and classification accuracy. It is easy to administer in busy clinics, enabling early detection of CI and facilitating appropriate interventions.

RESUMO

Background: Many autistic children experience motor skill deficits which can impact other areas of functioning, and research on therapeutic interventions for motor skills in autism is in a preliminary stage. Music-based therapies have been used extensively to address motor skills in non-autistic populations. Though a handful of studies exist on the effects of music-based therapies for movement in autistic children, none have investigated the possibility of administering sessions via telehealth. This mixed-methods pilot study investigated whether nine Neurologic Music Therapy (NMT)® sessions via telehealth would improve motor and attention skills in autistic children. Methods: Five autistic children between five and 10 years of age participated in the study, with support from their caregivers. Motor skills were assessed using the Bruininks-Oseretsky Test of Motor Proficiency second edition, short form (BOT-2 SF), and a selective attention and sustained attention task were taken from the Test of Everyday Attention for Children, Second Edition (TEA-Ch2). Caregivers and the two neurologic music therapists involved in the study provided qualitative input about the perceived effectiveness of telehealth NMT for the children involved. Their responses were analyzed using qualitative content analysis. Caregivers also filled out a Sensory Profile 2 assessment prior to the onset of sessions so that each child's sensory profile could be compared to their motor and attention results. Results: Statistically significant improvements in motor skills were observed between pre-test assessment and a two-week follow-up assessment. Results from attention test scores were not significant. Caregivers and neurologic music therapists generally perceived sessions positively and noted the importance of having caregivers actively involved. When compared with individual progress on the BOT-2 SF assessment, sensory profile results revealed that children with fewer sensory sensitivities tended to improve the most on motor skills. The improvements in motor skills and positive caregiver and therapist views of telehealth indicate that NMT motor interventions administered via telehealth are a promising avenue of therapeutic support for movement skill development in autistic children.

RESUMO

Ocean warming will continue to affect the growth, body condition and geographic distributions of marine fishes and understanding these effects is an urgent challenge for fisheries research and management. Determining how temperature is recorded in fish otolith carbonate, provides an additional chronological tool to investigate thermal histories, preferences and patterns of movement throughout an individual's life history. The influence of three water temperature treatments (22°C, 25°C, and 28°C) on hatchery-reared juvenile stout whiting, Sillago robusta, was tested using a controlled outdoor mesocosm system. Fish were measured for change in length and weight, and body condition was determined using bioelectrical impedance analysis. Sagittal otoliths were analysed for stable oxygen (δ18Ootolith) and carbon (δ13Cotolith) isotopes via isotope ratio mass spectrometry. Whiting kept at 22°C were significantly smaller and had diminished body condition compared to fish in 25°C and 28°C, which did not significantly differ from each other. The δ18O otolith values of stout whiting demonstrated a negative temperature-dependent fractionation relationship which was similar in slope but had a different intercept to the relationships reported for inorganic aragonite and other marine fish species. The δ13C otolith values also showed a negative relationship with water temperature, and the calculated proportion of metabolic carbon M in otoliths differed between fish reared in the coolest (22°C) and warmest (28°C) temperature treatments. Overall, the results suggest that stout whiting may have reached an upper growth threshold between 25°C and 28°C, and that growth and body condition may be optimised during warmer seasons and toward the northerly regions of their distribution. Otolith oxygen thermometry shows promise as a natural tracer of thermal life history, and species-specific fractionation equations should be utilised when possible to prevent errors in temperature reconstructions of wild-caught fish.

RESUMO

PURPOSE: Cardiogenic shock is associated with high mortality. In refractory shock, it is unclear if mechanical circulatory support (MCS) devices improve survival. We conducted a network meta-analysis to determine which MCS devices confers greatest benefit. METHODS: We searched MEDLINE, Embase, and Scopus databases through 27 August 2023 for relevant randomized controlled trials (RCTs) and propensity score-matched studies (PSMs). We conducted frequentist network meta-analysis, investigating mortality (either 30 days or in-hospital) as the primary outcome. We assessed risk of bias (Cochrane risk of bias 2.0 tool/Newcastle-Ottawa Scale) and as sensitivity analysis reconstructed survival data from published survival curves for a one-stage unadjusted individual patient data (IPD) meta-analysis using a stratified Cox model. RESULTS: We included 38 studies (48,749 patients), mostly reporting on patients with Society for Cardiovascular Angiography and Intervention shock stages C-E cardiogenic shock. Compared with no MCS, extracorporeal membrane oxygenation with intra-aortic balloon pump (ECMO-IABP; network odds ratio [OR]: 0.54, 95% confidence interval (CI): 0.33-0.86, moderate certainty) was associated with lower mortality. There were no differences in mortality between ECMO, IABP, microaxial ventricular assist device (mVAD), ECMO-mVAD, centrifugal VAD, or mVAD-IABP and no MCS (all very low certainty). Our one-stage IPD survival meta-analysis based on the stratified Cox model found only ECMO-IABP was associated with lower mortality (hazard ratio, HR, 0.55, 95% CI 0.46-0.66). CONCLUSION: In patients with cardiogenic shock, ECMO-IABP may reduce mortality, while other MCS devices did not reduce mortality. However, this must be interpreted within the context of inter-study heterogeneity and limited certainty of evidence.
