Frequent use of prescription NSAIDs among people with knee or hip osteoarthritis despite contraindications to or precautions with NSAIDs.

OBJECTIVE: To describe the use of non-steroidal anti-inflammatory drugs (NSAID), opioids, and physiotherapy (PT) among persons with newly diagnosed knee or hip osteoarthritis (OA) with and without NSAID contraindications or precautions. DESIGN: We used population-based register data to identify adults aged ≥35 as of January 1, 2014, residing in Skåne region (Sweden) between 2004 and 2013, without a previous knee or hip OA diagnosis. Among this cohort, we identified people with incident knee or hip OA diagnosis between 2014 and 2018 and the presence of contraindications to or precautions for oral NSAIDs at the time of OA diagnosis. We estimated the risk of 1) regular oral NSAID use, 2) regular opioid use, and 3) PT during the first year after diagnosis among those with vs. without contraindications or precautions using confounder-adjusted logistic regression with standardization. RESULTS: We identified 35,173 persons with newly diagnosed OA, of whom 3257 and 8351 had ≥1 contraindication to oral NSAIDs and ≥1 precaution, respectively. Overall, 27% of individuals used oral NSAIDs (with or without opioids or PT), 10% used opioids, and 57% attended PT. Among patients with contraindications, 21% used oral NSAIDs compared to 31% without (absolute adjusted difference -0.06 (95% CIs: -0.08, -0.05)), 53% vs 59% used PT (adjusted difference -0.03 (-0.05, -0.01)), while 14% vs. 8% had prescribed dispensed opioids (adjusted difference 0.02 (0.01, 0.03)). Similar results were observed for those with precautions. CONCLUSIONS: We highlight the need for safer treatment options. People with OA and contraindications/precautions to NSAIDs have a higher risk of opioid use, slightly lower risk of PT use, and continue to be prescribed NSAIDs.

Acute treatment of migraine: quantifying the unmet need through real-world data in Italy.

OBJECTIVE: This study is describing subjects with migraine interrupting or not receiving triptans for acute treatment and providing a national-level estimate of people who might benefit from different therapeutic approaches. METHODS: This is a retrospective analysis using IQVIA Longitudinal Patient Database. Starting from 18 + years old individuals with migraine, we selected two cohorts: subjects with triptans prescriptions before and no triptans prescriptions after Index Date (triptan withdraw) and subjects without triptans prescriptions both before and after Index Date (no triptan prescriptions). Index Date was the first record of a health encounter for migraine in 2019. Individuals with cardiovascular disease (CVD) within no triptan prescriptions group were also quantified. RESULTS: Triptan withdraw and no triptan prescriptions cohorts numbered 605 and 3270, respectively, 5% and 29% of subjects with migraine. Mean age was 47 and 51 years respectively; women were more represented (~ 80%). Hypertension and thyroid disease were most frequent comorbidities; non-steroidal anti-inflammatory drugs were among most frequently recorded treatments. Subjects with CVD within no triptan prescriptions cohort were 621 and with triptan withdraw cohort subjects represented the basis to estimate those who might benefit from alternative options for the acute treatment of migraine, who were around 60,000 and accounted for 11% of subjects seeking primary care due to migraine. CONCLUSIONS: This analysis provides a real-word estimate of Italian people that might benefit from different therapeutic approaches as an alternative to triptans, which sometimes might be not effective and/or poorly tolerated. Such estimate should be intended as the lower limit of a wider range due to strict criteria adopted.

Contraindications to tissue plasminogen activator thrombolysis for acute lower extremity ischemia.

OBJECTIVE: Previous randomized prospective trials have demonstrated the effectiveness of transcatheter tissue plasminogen activator (tPA) thrombolysis in treating acute limb ischemia (ALI) compared to conventional surgery. These pivotal trials have also highlighted contraindications for these procedures. Given recent advancements in techniques and technology, our aim is to reassess the relevance of these contraindications in contemporary practice. METHODS: A retrospective chart analysis was performed utilizing the inpatient medical records of consecutive individuals who underwent tPA treatment for acute limb ischemia (ALI) from September 2016 to April 2022. Inclusion criteria encompassed patients aged 18 and above displaying clinical symptoms and imaging evidence of ALI within 14 days. All patients received tPA with suction thrombectomy following the fast-track thrombolysis protocol. In cases where a persistent thrombus or stenosis was detected, catheter-directed thrombolysis was considered overnight, and patients underwent angiography and reassessment in the operating room subsequently. RESULTS: Patients were classified into two groups based on the STILE trial's established contraindications for endovascular treatment in acute limb ischemia (ALI). If a patient had any of these contraindications, they were placed in the contraindicated group. This resulted in 24 patients (32%) in the contraindicated group and 52 patients (68%) in the non-contraindicated group. No statistically significant demographic variations were observed between these groups. Contraindications in our study included uncontrolled hypertension (12/24, 50%), recent invasive procedures (7/27, 29%), history of cerebrovascular accident (CVA) within 6 months (3/24, 12%), and intracranial malformation/neoplasms (2/24, 8%). Three patients within the non-contraindicated group experienced bleeding complications: two with puncture site bleeds and one with nasal bleeding. In contrast, one patient in the contraindicated group had transient postoperative hematuria. There were no significant differences in bleeding complications observed between the two groups (p = .771). Additionally, no amputations were observed within our population. CONCLUSIONS: In light of our study results and advancements in endovascular therapies, we can now safely and efficiently treat patients who were previously considered contraindicated for such treatments. It is essential to individualize treatments and carefully balance the risks and benefits of endovascular versus open surgical revascularization for these patients. Additionally, we believe that the nearly 30-year-old guidelines for endovascular therapies need to be revisited and updated to align with modern technology.

Use of contraindicated antiretroviral drugs in people with HIV/HCV coinfections receiving HCV treatment with direct-acting antivirals-Results from the EuroSIDA study.

OBJECTIVES: Our objective was to determine whether antiretroviral drugs (ARVs) were used according to the European AIDS Clinical Society (EACS) guidelines for people with HIV/hepatitis C virus (HCV) coinfection treated with direct-acting antivirals (DAAs) between 30 November 2014 and 31 December 2019 in the pan-European EuroSIDA study. METHODS: At each publication date of the EACS guidelines, plus 3 and 6 months, we calculated the number of people receiving DAAs with potential and actual ARV contraindications ('red shading' in the EACS guidelines). We used logistic regression to investigate factors associated with using contraindicated ARVs. RESULTS: Among 1406 people starting DAAs, the median age was 51 years, 75% were male, 57% reported injected drug use as an HIV risk, and 76% were from western Europe. Of 1624 treatment episodes, 609 (37.5%) occurred while the patient was receiving ARVs with potential contraindications; among them, 38 (6.2%; 95% confidence interval [CI] 4.3-8.2) involved a contraindicated ARV (18 non-nucleoside reverse transcriptase inhibitors), 16 involved protease inhibitors, and four involved integrase strand transfer inhibitors. The adjusted odds of receiving a contraindicated ARV were higher (3.25; 95% CI 1.40-7.57) among participants from east/central east Europe (vs. south) and lower (0.22; 95% CI 0.08-0.65) for 2015-2018 guidelines (vs. 2014). In total, 29 of the 32 (90.6%) patients receiving a contraindicated ARV and 441 of the 461 (95.7%) with potential ARV contraindications experienced a sustained virological response ≥12 weeks after stopping treatment (SVR12; p = 0.55). CONCLUSION: In this large heterogenous European cohort, more than one-third of people with HIV/HCV coinfection received DAAs with potential ARV contraindications, but few received a contraindicated ARV. Use of contraindicated ARVs declined over time, corresponding to the increased availability of ARV therapy regimens without interactions with DAA across Europe. Participants who received a contraindicated DAA and ARV combination still had a high rate of SVR12.

Inconsistencies of absolute drug-drug contraindication reports: Analysis of Summaries of Product Characteristics of commonly prescribed drugs.

AIMS: Prescribing information should follow a defined structure to help prescribers easily find required information. Often information appears in different sections of Summaries of Product Characteristics (SmPCs) in an inconsistent way. Still unknown is how this inconsistency affects absolute contraindications and how it can be improved. Thisstudy aimed to evaluate the structure of absolute contraindications in SmPCs based on absolute drug-drug contraindications (DDCI) in the section 'contraindications' and references to sections 'special warnings and precautions for use' (here as 'warnings') and 'interaction with other medicinal products and other forms of interaction' (here as 'interactions'). METHODS: SmPCs of 693 commonly prescribed drugs were analysed regarding absolute DDCI in 'contraindications' sections. References to sections on 'warnings' and 'interactions' were evaluated to characterize information provided about DDCI. RESULTS: Of 693 analysed SmPCs, 138 (19.9%) contained ≥1 absolute DDCI. Of 178 SmPCs that referred to sections on 'warnings' or 'interactions', 131 (73.6%) did not contain further information on absolute DDCI, whereas 47 (26.4%) did. Such additional information was found in sections on 'interactions' and 'warnings' in 41 (87.2%) and 9 (19.1%) SmPCs, respectively. CONCLUSIONS: Information regarding absolute DDCI was found not only in sections on 'contraindications' but also in sections on 'warnings' and 'interactions'. Information was not given with consistently straightforward phrasing and structure and so can leave uncertainty for prescribers. To improve drug safety, clear definitions and wording for absolute and relative contraindications should be provided, ideally in tables.

Ten open questions in migraine prophylaxis with monoclonal antibodies blocking the calcitonin-gene related peptide pathway: a narrative review.

The monoclonal antibodies (mAbs) blocking the calcitonin-gene related peptide (CGRP) pathway, collectively called here "anti-CGRP/rec mAbs", have dramatically improved preventive migraine treatment. Although their efficacy and tolerability were proven in a number of randomized controlled trials (RCTs) and, maybe even more convincingly, in real world settings, a number of open questions remain. In this narrative review, we will analyze published data allowing insight in some of the uncertainties related to the use of anti-CGRP/rec mAbs in clinical practice: their differential efficacy in migraine subtypes, outcome predictors, switching between molecules, use in children and adolescents, long-term treatment adherence and persistence, effect persistence after discontinuation, combined treatment with botulinum toxin or gepants, added-value and cost effectiveness, effectiveness in other headache types, and potential contraindications based on known physiological effects of CGRP. While recent studies have already provided hints for some of these questions, many of them will not find reliable and definitive answers before larger studies, registries or dedicated RCTs are available.

Evaluation of Potential Drug-Drug Interactions and Association with Adverse Drug Reactions in Predialysis Chronic Kidney Disease Patients at Indonesian National Referral Hospital.

BACKGROUND: Chronic kidney disease (CKD) is often accompanied by a variety of comorbidities that require several medications thus, polypharmacy is unavoidable. One of the consequences of polypharmacy is the occurrence of potential drug-drug interactions (DDI). The aim of this study is to evaluate the profile of DDI in pre-dialysis CKD patients and to identify the possible adverse drug reactions (ADR) due to DDI. METHODS: This cross-sectional study includes stage 3-5 pre-dialysis CKD patients at a referral hospital in Indonesia in 2019 - 2020. Data were collected from the electronic health record and the hospital's medical record. The prescriptions were analysed for potential DDI using Micromedex software and ADRs assessment through clinical symptoms and laboratory data abnormalities. RESULTS: A total of 106 patients were included in the study, around 60 (56.6%) patients received more than six medications. There were 111 types of medications prescribed with the most frequently prescribed drug was bisoprolol (36.5%). The proportion of patients who received treatment with a potential DDI was 76% (81 patients), while the proportion of patients who experienced ADR was 28% (23 patients). The most prevalent ADRs were hyperglycaemia, hypertension, hyperkalaemia, and hypotension. Cardiovascular disease had a statistically significant relationship with ADR suspected due to DDI (p = 0.03). CONCLUSION: A significant number of potential DDI were seen in the prescriptions of stage 3-5 pre-dialysis CKD patients at a referral hospital in Indonesia between 2019 - 2020. Cardiovascular disease was identified as the most common risk factor for ADR suspected caused by DDI.

Indications for replantation and factors that predict success.

Since the advent of replantation techniques, there has been uneven progress in terms of success-even considering whether success is defined as continued perfusion of the digit or long term functional outcomes. Early enthusiasm and success have not been maintained despite increasing familiarity with microsurgical techniques and greater understanding of how to optimize outcomes for the individual components of replantation such as tendon repair, nerve repair, and osteosynthesis. Practitioners participating in the care of patients undergoing replantation should be familiar with the history and current understanding of both the indications and contraindications for the procedure, post-operative rehabilitation, and factors contributing to functional outcomes. A review of the literature from the first publications on the topic demonstrates evolution in practice and understanding of which patients should be indicated for replantation. Indications can be considered in three broad categories: injury factors, patient factors, and care context factors. These factors intersect with one another and can inform the surgeon pre-operatively regarding the most likely outcome for a given patient. This insight is critical to discuss pre-operatively with the patient in order to make a shared decision about how to manage their injury.

Direct Oral Anticoagulants Versus Warfarin in the Treatment of Cerebral Venous Thrombosis (ACTION-CVT): A Multicenter International Study.

BACKGROUND: A small randomized controlled trial suggested that dabigatran may be as effective as warfarin in the treatment of cerebral venous thrombosis (CVT). We aimed to compare direct oral anticoagulants (DOACs) to warfarin in a real-world CVT cohort. METHODS: This multicenter international retrospective study (United States, Europe, New Zealand) included consecutive patients with CVT treated with oral anticoagulation from January 2015 to December 2020. We abstracted demographics and CVT risk factors, hypercoagulable labs, baseline imaging data, and clinical and radiological outcomes from medical records. We used adjusted inverse probability of treatment weighted Cox-regression models to compare recurrent cerebral or systemic venous thrombosis, death, and major hemorrhage in patients treated with warfarin versus DOACs. We performed adjusted inverse probability of treatment weighted logistic regression to compare recanalization rates on follow-up imaging across the 2 treatments groups. RESULTS: Among 1025 CVT patients across 27 centers, 845 patients met our inclusion criteria. Mean age was 44.8 years, 64.7% were women; 33.0% received DOAC only, 51.8% received warfarin only, and 15.1% received both treatments at different times. During a median follow-up of 345 (interquartile range, 140-720) days, there were 5.68 recurrent venous thrombosis, 3.77 major hemorrhages, and 1.84 deaths per 100 patient-years. Among 525 patients who met recanalization analysis inclusion criteria, 36.6% had complete, 48.2% had partial, and 15.2% had no recanalization. When compared with warfarin, DOAC treatment was associated with similar risk of recurrent venous thrombosis (aHR, 0.94 [95% CI, 0.51-1.73]; P=0.84), death (aHR, 0.78 [95% CI, 0.22-2.76]; P=0.70), and rate of partial/complete recanalization (aOR, 0.92 [95% CI, 0.48-1.73]; P=0.79), but a lower risk of major hemorrhage (aHR, 0.35 [95% CI, 0.15-0.82]; P=0.02). CONCLUSIONS: In patients with CVT, treatment with DOACs was associated with similar clinical and radiographic outcomes and favorable safety profile when compared with warfarin treatment. Our findings need confirmation by large prospective or randomized studies.

Health care professionals' understanding of contraindications for physical activity advice in the setting of stem cell transplantation.

PURPOSE: Most patients receiving a hematopoietic stem cell transplantation (HSCT) are able to tolerate and benefit from physical activity (PA). Therefore, it is important that health care professionals (HCPs) advise patients to perform PA before, during, and after transplantation. By understanding which medical conditions and safety issues are associated with the (non-) promotion of PA, concrete actions and interventions can be planned and implemented. METHODS: Physicians (N = 51), nurses (N = 52), and physical therapists (N = 26) participated in a nationwide cross-sectional online survey. HCPs' understanding of 15 medical conditions as contraindications for PA was assessed. Significant group differences were determined using chi-square analysis. RESULTS: Acute infection was the only condition which was considered as contraindication by all HCPs (62.7%). Cachexia (78%), having a stoma (91%), or port (96.2%), psychological problems (88.4%), and leukopenia (83.3%) were not considered as contraindications. Six conditions were rated inconsistently between the groups, whereas physicians had the least concerns regarding PA. Physicians with an additional training in PA perceived a platelet count of ≤ 50,000/µl significantly less often as contraindication (p < 0.05). CONCLUSION: The large number of potentially-answers especially in nursing staff and physical therapists might reflect caution or uncertainty. There is a clear need for a good multidisciplinary cooperation between all HCPs in order to support patients to confidently engage in PA. Furthermore, education possibilities and evidence-based courses to build knowledge regarding safety concerns should be the standard practice in the setting of HSCT. The investigative nature of the paper indicates that certain trends should be interrogated in a causal-longitudinal design.

Should be a locally advanced colon cancer still considered a contraindication to laparoscopic resection?

BACKGROUND: The role of elective laparoscopic resection (LR) for the treatment of locally advanced colon cancer (LACC) is unclear. Most studies have retrospectively investigated the outcomes of LR for pT4 cancers, while clinical T4 (cT4) cancers are excluded in the large randomized controlled trials comparing LR and open resection (OR). The aim of this study was to investigate the outcomes in patients undergoing elective LR for LACC. METHODS: A prospective single-institution database including consecutive patients undergoing elective LR for clinical LACC (high-risk T3 or T4 N0-2) between March 1996 and March 2017 was retrospectively reviewed. A multivariate analysis was performed to identify predictors of conversion to OR and risk factors for adverse oncologic outcomes. RESULTS: A total of 300 patients undergoing LR for LACC were included. A multi-visceral resection was needed in 17 (5.7%) patients. A total of 63 (21%) LRs were converted to OR, mainly due to suspected adjacent organ invasion (82.5%) or obesity (9.5%). Overall postoperative Clavien-Dindo 3-4 complication rate was 4.7%, with no significant differences between completed and converted LRs. Final pathology showed 18 (6%) pT2, 215 (71.7%) pT3, 54 (18%) pT4a, and 13 (4.3%) pT4b cancers. A R0 resection was achieved in 98.3% of patients. On multivariate analysis, tumor size ≥ 7 cm and tumor site (splenic flexure) were the independent risk factors for conversion to OR. A pT4 colon cancer and LNR of 0.25 or greater, but not conversion to OR, were independently associated with both poorer OS and DFS. CONCLUSION(S): Clinical LACC should not be considered a contraindication to LR itself. Bulky tumors ≥ 7 cm and splenic flexure cancers are at higher risk of conversion to OR; however, there is no increased postoperative morbidity or adverse oncologic outcomes in converted patients.

[Glucocorticoid-induced osteoporosis-Focus treatment (part 2)]. / Glukokortikoid-induzierte Osteoporose ­ Fokus Therapie (Teil 2).

The following substances are approved for the treatment of glucocorticoid-induced osteoporosis: the oral bisphosphonates alendronate and risedronate, the intravenous bisphosphonate zoledronate, the RANKL antibody denosumab as antiresorptive substances and teriparatide as osteoanabolic substance. In comparison to placebo a reduction of vertebral fractures is proven for all mentioned substances. Thereby, teriparatide is more effective than alendronate and risedronate with respect to the reduction of vertebral fractures. The severity of osteoporosis, especially the presence of osteoporotic fractures, the approach of treatment (preventive or curative) and contraindications are factors that are important for the differentiated application of the mentioned substances. Furthermore, it must be noted that the effect of osteoanabolic treatment must be stabilized by a subsequent antiresorptive treatment and that after termination of antiresorptive treatment with denosumab a temporary bisphosphonate treatment is required to prevent a rebound phenomenon.

[Imaging in manual medicine-Necessary and interesting aspects]. / Bildgebung in der Manuellen Medizin ­ Notwendiges und Interessantes.

The German Society for Manual Medicine no longer demands mandatory X­ray diagnostics prior to high-velocity, low-amplitude manipulation. Indication is based on the general justification as a result of anamnesis and clinical examination. With appropriate indications, imaging primarily serves to exclude contraindications. The use of X­ray diagnostics to determine the treatment technique or direction is obsolete, especially in infants. Detection of segmental dysfunction as the therapeutic indication is of scientific interest only. Other possible objectives of imaging are detection of a non-functional cause of pain or prediction of therapeutic success. In either case, study results to date contradict general imaging, as there is no significant correlation between detected changes and existing or developing pain. In particular, the significance of a Modic lesion is still to be regarded as open according to studies to date.

Upper Hemi-Sternotomy Provides Benefit for Patients with Isolated or Combined Mitral Valve Surgery.

Background and objectives: Certain clinical and anatomical conditions are absolute or relative contraindications for safe mitral valve surgery via the right mini-thoracotomy access. It is uncertain whether patients with these contraindications may benefit from the less invasive approach via upper hemi-sternotomy compared to standard full sternotomy. Materials and methods: Out of 2052 mitral valve surgery patients, operated from 6/04 through 2/19, 1535 were excluded due to the different criteria for eligibility to both approaches. Out of these, 350 received full sternotomy and 167 upper hemi-sternotomy. After propensity score matching, 164 pairs were analyzed for operative variables, postoperative complications and 30-day and one-year survival. Results: Upper hemi-sternotomy was associated with a survival benefit of 30 days (99.4% vs. 82.1%; p < 0.001) and one-year (93.9% vs. 79.9% p < 0.001, HR 0.26, 95% CI 0.14-0.49). Cardiopulmonary bypass and aortic cross-clamp times were comparable in both groups. Upper hemi-sternotomy resulted in less low cardiac output syndrome (18.9% vs. 31.1%; p = 0.011); ventilation time (8 vs. 13 h; p < 0.001), length of intensive care stay (1 vs. 2 days; p < 0.001) and total hospital stay (8 vs. 9 days; p < 0.001) were shorter in the upper hemi-sternotomy group. Conclusion: In patients undergoing mitral valve surgery, upper hemi-sternotomy is associated with short- and mid-term survival benefits as well as lower postoperative complication rates compared to full sternotomy. Hence, the less invasive upper hemi-sternotomy can be a valid approach in patients with contraindications for right mini-thoracotomy.

[Atrial fibrillation and the limits of oral anticoagulation: for whom are left atrial appendage occluders suitable?] / Vorhofflimmern und Grenzen der oralen Antikoagulation ­ für wen eignen sich Vorhofohrokkluder?

BACKGROUND: Patients with atrial fibrillation are at a significantly increased risk of thromboembolic events, especially ischemic strokes. Oral anticoagulation reduces this risk, but cannot be used in some patients for various reasons and is associated with a relevantly increased risk of bleeding. As an alternative for prophylaxis of thromboembolic events in patients with atrial fibrillation, there are different options of left atrial appendage closure. AIM: This article explains the possibilities of interventional atrial occlusion as well as the suitable patient clientele using an overview of the currently available systems for atrial occlusion, a guideline for patient selection and a summary of the current scientific data. CONCLUSION AND AVAILABLE SCIENTIFIC DATA: In carefully selected patients suffering from atrial fibrillation with relative or absolute contraindications for oral anticoagulation, interventional closure of the atrial appendage is a safe alternative for prophylaxis against thromboembolic events. The currently available scientific evidence from randomized controlled trials is sparse. Nevertheless, extensive amounts of registry study data suggest a benefit, while the results of several large randomized controlled trials are expected in the coming years.

Total ankle arthroplasty with the use of Zimmer prosthesis and a review of the results of previous research conducted in this field.

The aim of this article is to describe surgical technique and early results of Total Ankle Replacement (TAR) from lateral approach using Zimmer TM prosthesis. The study uses theoretical knowledge which is the result of research conducted by other authors, and practical knowledge due to the fact that our center performs that type of operation. Arthrodesis as the current standard in the treatment of advanced degenerative ankle disease, apart from its advantages, also has many disadvantages. The relative durability and reduction of the patients' pain have been achieved at the expense of the adjacent joints. Their accelerated arthrosis is the result of compensatory loads as a consequence of change in foot biomechanics. That determined implementation of solutions that will guarantee elimination of pain in the ankle joint, preserve its motor function and improve gait, while having no negative impact on the mobility of adjacent joints.

A Review of Heart Transplantation for Adults With Congenital Heart Disease.

As techniques for corrective and palliative surgery in congenital heart disease improve, the number of patients surviving to become adults with congenital heart disease (ACHD) has increased. A significant proportion of these patients will progress to develop advanced heart failure, the symptoms of which vary, complicating prediction of life expectancy. Unlike acquired heart failure, there is a lack of evidence-based treatments with which to relieve symptoms and prolong survival. As a result, a number of ACHD patients will proceed to heart transplantation. Referral for transplantation should be considered early, given the difficulties with prognostication, and should take place in a center with surgical and medical expertise in the management of ACHD patients and transplantation. In addition to assessing contraindications to heart transplantation for the general population, factors specific to ACHD should be considered. These include pulmonary hypertension, cyanosis, liver disease, previous surgeries, and the degree of allosensitization. Once listed for transplantation, ACHD patients spend longer on the waitlist, and are more likely to die or be delisted than their non-ACHD counterparts. Mechanical circulatory support is used less commonly as a bridge to transplantation given the difficulties with implantation and unfamiliarity of use. Recent evidence suggests that with increased experience and early consideration, mechanical circulatory support can be used successfully as a bridging therapy. Despite a higher early mortality, long-term survival is greater for ACHD patients after transplant due to younger age and relative lack of comorbidities. With early referral, careful assessment of each individual's unique anatomy and physiology, and care in a center experienced with ACHD patients and transplantation, outcomes will continue to improve.

Case report of successful peripheral veno-arterial extracorporeal membrane oxygenation in a patient with chronic type B aortic dissection.

A case report of successful application of peripheral veno-arterial extracorporeal membrane oxygenation in a patient with chronic type B aortic dissection and myocardial stunning to bridge to recovery was presented. Good outcomes from the application of peripheral veno-arterial extracorporeal membrane oxygenation in aortic dissection have rarely been reported, and the considerations of starting veno-arterial extracorporeal membrane oxygenation in this situation were seldom discussed. The orthodox that peripheral veno-arterial extracorporeal membrane oxygenation is an absolute contraindication for initiation of peripheral veno-arterial extracorporeal membrane oxygenation should be challenged. With proper planning and real-time transesophageal echocardiography-guided cannulation, peripheral veno-arterial extracorporeal membrane oxygenation is possibly beneficial. The considerations and echocardiography-guided techniques would be discussed in this report.

Practical instructions for using drugs in CT and MR cardiac imaging.

The progressive increase in numbers of noninvasive cardiac imaging examinations broadens the spectrum of knowledge radiologists are expected to acquire in the management of drugs during CT coronary angiography (CTCA) and cardiac MR (CMR) to improve image quality for optimal visualization and assessment of the coronary arteries and adequate MR functional analysis. Aim of this review is to provide an overview on different class of drugs (nitrate, beta-blockers, ivabradine, anxiolytic, adenosine, dobutamine, atropine, dipyridamole and regadenoson) that can be used in CTCA and CMR, illustrating their main indications, contraindications, efficacy, mechanism of action, metabolism, safety, side effects or complications, and providing advices in their use.

[Decision for total hip arthroplasty-the surgeons' view]. / Indikationsstellung zur Hüfttotalendoprothese ­ die ärztliche Perspektive.

BACKGROUND: The decision for total hip arthroplasty (THA) is based on pain, loss of function, radiological changes and failed conservative therapy. These criteria are rarely based on systematic research and have not been integrated in generally accepted treatment guidelines. Aim of our study was, therefore, to analyse which decision criteria German orthopaedic and trauma surgeons use in order to recommend THA for patients with hip osteoarthritis. MATERIALS AND METHODS: From 10/2019 to 07/2020 we conducted a nation-wide survey among 218 orthopaedic and trauma surgeons about their criteria for and against THA surgery, as well as their treatment objectives. RESULTS: 147 fully completed questionnaires were analysed. Pain (99%), limitation of movement (99%), as well as impairment of walking distance (97%), and the subjective burden (97%) were the most frequent criteria. 97% and 96% of surgeons consider prescription of analgesics and physical therapy, as well as a lack of their effectiveness, as criteria for THA. 87% see radiological changes grade Kellgren & Lawrence III as threshold. A recommendation against surgery is triggered by obesity (BMI ≥ 40 kg/m2) in 48% and by the presence of an active infection in 96%. CONCLUSIONS: Current surgeons' practice criteria of recommendations for THA in Germany seem to reflect widely nationally and internationally discussed recommendations. Particular attention is given to patient factors like pain, loss of function and subjective burden, as well as previous conservative treatment and contraindications, like poorly controlled diabetes or an active infection, whereas morbid obesity is not seen as contraindication by all surgeons.
