Background: While evidence-based indications are established for medial UKA, the optimal indications for lateral UKA have not received as much attention. There exists significant anatomical, osteoarthritis phenotype, kinematic, and surgical technique differences between medial and lateral UKA. The indications for the two procedures may therefore not be identical. Hence, this review aims to access the indications and contraindications in published cohort studies on lateral UKA, to assess if consensus exists., Methods: In May 2024, a systematic review was carried out following the Preferred Reporting Item for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Cohort studies on lateral UKA with a clear report of indications were included. Data on indications and contraindications were extracted to evaluate consensus. Furthermore, outcomes related to expanding or testing indications for lateral UKA were obtained., Results: 38 studies were included. Lateral UKA was mostly performed for primary lateral osteoarthritis. The most reported indications were moderate to severe lateral osteoarthritis, with full-thickness cartilage in the medial compartment, intact ligaments, a correctable valgus deformity, and a flexion contracture < 10-15 degrees. The most reported contraindications were inflammatory arthritis and severe patellofemoral involvement. Eight studies investigated different indications on outcomes after lateral UKA; suggesting better outcomes for primary lateral osteoarthritis, no significant impact from the state of the patellofemoral joint, and conflicting results regarding age and weight., Conclusion: While the literature suggests that some agreement does exist regarding indications for lateral UKA, a strong consensus was not found, indicating that well-defined and consensus-based indications for lateral UKA do not yet exist., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 The Authors.

The term "allergy" is inaccurate for the vast majority of the contents in the current allergy fields of electronic health records (EHRs). While EHRs have transformed access to health information and streamlined the delivery of care, their ability to reliably indicate medications, vaccines, or foods that mandate avoidance versus preferences or mild intolerances, is suboptimal. The current systems are reactive instead of being proactive and frequently fail to communicate the appropriate course of action. This Position Statement of the American Academy of Allergy, Asthma and Immunology (AAAAI) advocates for a change in terminology. The section of the EHR currently labeled "allergies" should be renamed "alerts." The term "alert" accurately captures the purpose of this section without incorrectly assigning an allergic mechanism, and prioritizes easily understood and actionable labels. This change has the potential to simultaneously improve patient safety and care. This shift will be the first step in the transformation of the alerts section of the EHR. This document provides a framework for categorizing what should be included in this section. Enacting these changes will require EHR and clinical decision support vendors, healthcare and data standard regulators, allergists, and the larger health care community to work together to bring about these important advances., (Copyright © 2024 American Academy of Allergy, Asthma & Immunology.

This manuscript provides practical insights, tips, and lessons particularly valuable for early-career healthcare professionals new to using ketogenic diet therapy (KDT) in clinical practice. The review aims to be accessible, emphasizing actionable knowledge that can be directly applied in a clinical setting. The KDT for epilepsy includes not only the classic KDT but also the modified Atkins diet, the medium-chain triglyceride ketogenic diet, and the low glycemic index treatment. This highly effective non-pharmacological treatment can be rapidly implemented for patients with drug-resistant epilepsy. Identifying suitable candidates and conferring criteria for selecting patients who are likely to benefit ('good responder') from the ketogenic diet is critical for earlier intervention minimizing the burden of seizures and long-term polytherapy. On the other hand, this article outlines conditions where the ketogenic diet may not be appropriate, such as in patients with specific metabolic disorders, representing contraindications or cautions where there are concerns about adherence. Finally, the use of KDT in special settings (e.g., ICU) and how to deal with the most common side effects and abnormal laboratory results are provided based on an updated review and the experience from three level three epilepsy centers., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Inc.

Background: Surgical stabilization of rib fractures (SSRF) has shown benefits for rib fracture patients. However, the incidence of SSRF performed remains low. We compare our institution's rib fracture patients meeting criteria for SSRF versus those actually receiving the operation, hypothesizing a significant portion are not undergoing SSRF., Methods: A retrospective review of rib fracture patients presenting to our Level 1 trauma center from 1/2016 to 4/2023. Patients were categorized as those who met SSRF inclusion criteria versus those who didn't based on the 2023 Chest Wall Injury Society (CWIS) SSRF Guidelines. Basic demographics were obtained. Patients meeting SSRF criteria were divided into those who received SSRF versus those who didn't. Outcomes of interest included type and frequency of SSRF indications and frequency of absolute/relative contraindications. Descriptive statistics were used. Median test and t-test were used for statistical analysis. Statistical significance was set at p < 0.05., Results: A total of 3,432 patients presented with ≥1 rib fracture(s). Of those, 1,573(45.8 %) met SSRF inclusion criteria. These patients were predominantly male, with mean age of 57.4(±18.5) and a similar Injury Severity Score but significantly higher chest-Abbreviated Injury Score of 3 (Interquartile range 3,4)(p = 0.048). Only 458(29.1 %) patients underwent SSRF, leaving 1,115(70.9 %) managed non-operatively, of which 215(19.3 %) were ventilated and "failure to wean from the ventilator" was the most common (81.4 %) indication for SSRF. Of the 900(80.7 %) non-ventilated patients managed non-operatively, 659 (69.9 %) had ≥two indications for SSRF, 382(34.3 %) had zero relative contraindications and 394(35.3 %) had one relative contraindication for SSRF. Lastly, 52.6 % of patients in this cohort had reported "clicking/popping" of their fractures., Conclusion: Only 29.1 % of patients meeting criteria for SSRF had the operation based on data from our institution. There may be additional opportunity to benefit this cohort of patients meeting SSRF criteria but not undergoing surgery., Competing Interests: Declaration of competing interest Dr. Zachary Bauman is a paid educational consultant for KLS-Martin, Zimmer-Biomet and Atricure, and Smith&Nephew.

Malnutrition is estimated to affect roughly 30%-80% of patients with inflammatory bowel disease (IBD). In those patients who cannot tolerate sufficient oral nutrition or there is no possibility for placing an enteral nutrition tube, parenteral nutrition offers a lifesaving alternative. However, this is not without risk. For patients with IBD, understanding the indications, contraindications, and complications associated with parenteral nutrition is crucial. In this review, we will discuss the indications and contraindications for parenteral nutrition in patients with IBD, the common complications associated with intravenous nutrition, the use of parenteral nutrition in special populations, such as in pediatric and perioperative patients, and the impact of parenteral nutrition on IBD-related outcomes., (© 2024 American Society for Parenteral and Enteral Nutrition.)

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., (© 2023. The Author(s).)

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., (© 2024. The Author(s).)

Background: Despite the introduction of the diagnosis-related groups (DRG) system, costs in the German healthcare system have risen continuously for years. In order to reduce costs the federal government is aiming to shift inpatient services to the outpatient sector. Outpatient services affect many areas of medicine, including proctological operations as these are common and can often be carried out on an outpatient basis., Objective: The aim of the present work is to discuss which areas of proctology are suitable for outpatient treatment and which structural requirements are necessary., Material and Methods: The present article is intended to provide a narrative overview with reference to the literature on the topic of outpatient care in proctology. A literature search was carried out using the following keywords: outpatient care, selective sector-level remuneration, day care, proctological operations, AOP catalog and hybrid DRG., Results: In proctology, outpatient surgical care is implementable in many cases; however, not every patient is suitable for this. In addition to previous illnesses, patient compliance and the possibility of postoperative care from relatives must also be taken into account. In addition, emergency treatment must be guaranteed. Contraindications include severe heart and circulatory diseases as well as severe coagulation or organ dysfunction. Extensive abscesses, complex fistulas or sphincter reconstructions should be surgically treated in an inpatient setting. The prerequisite for successful outpatient care is to make the sector boundaries between outpatient and inpatient patient care more permeable and to adequately remunerate the interventions., Conclusion: In addition to the surgical indications, the prerequisites for successful proctological operations are the correct assessment of the operational capability and compliance. From an organizational and economic perspective, better networking between outpatient and inpatient treatment and equal remuneration across the sector boundaries are crucial., Competing Interests: Einhaltung ethischer Richtlinien.

Outpatient surgery in the treatment of hernia is currently a major challenge for patients and treating physicians in Germany due to the new legal regulations (key term hybrid diagnosis-related groups, DRG). Despite large economic challenges and empty funds, the principle of medical treatment is still the patient-oriented scientifically founded medicine. Although outpatient treatment would be very desirable, clear medical knowledge should the basis for the justification of surgical strategies: outpatient short hospitalization (24h) or fully inpatient hospitalization (>24h). A completely outpatient treatment of hernias is not meaningful and the demarcation of outpatient, short inpatient and inpatient treatment should be demonstrated in a risk-adjusted manner. A classification is essential, particularly against the background of an intersectoral hybrid DRG., Competing Interests: Einhaltung ethischer Richtlinien.

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., Competing Interests: Declaration of Competing Interest TN, AD, AT, ME have no conflict of interest to declare., (Copyright © 2024 Osteoarthritis Research Society International.

We present the case of an 82-year-old female with obstructive jaundice secondary to a malignant distal biliary stricture. Endoscopic ultrasound-guided hepaticogastrostomy (EUS-HGS) was performed. The presence of a giant hiatal hernia induced dynamic liver movement during respiration, leading to unstable scope positioning. Despite the successful placement of a long, partially covered metal stent from the left intrahepatic bile duct to the intra-abdominal stomach, computed tomography performed three days later revealed free air and an increased distance between the liver and stomach. A subsequent endoscopy confirmed impending stent migration into the abdominal cavity, necessitating the insertion of an additional metal stent through the existing stent's mesh. The presence of a giant hiatal hernia may be considered a relative contraindication for EUS-HGS due to dynamic movements of the stomach and liver during respiration, which can cause stent migration, increased air leakage, and difficulty in establishing a stable fistula between these organs., Competing Interests: Human subjects: Consent was obtained or waived by all participants in this study.

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., Competing Interests: Declaration of conflicting interestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

The 2024 U.S. Medical Eligibility Criteria for Contraceptive Use (U.S. MEC) comprises recommendations for the use of specific contraceptive methods by persons who have certain characteristics or medical conditions. These recommendations for health care providers were updated by CDC after review of the scientific evidence and a meeting with national experts in Atlanta, Georgia, during January 25-27, 2023. The information in this report replaces the 2016 U.S. MEC (CDC. U.S. Medical Eligibility Criteria for Contraceptive Use, 2016. MMWR 2016:65[No. RR-3]:1-103). Notable updates include 1) the addition of recommendations for persons with chronic kidney disease; 2) revisions to the recommendations for persons with certain characteristics or medical conditions (i.e., breastfeeding, postpartum, postabortion, obesity, surgery, deep venous thrombosis or pulmonary embolism with or without anticoagulant therapy, thrombophilia, superficial venous thrombosis, valvular heart disease, peripartum cardiomyopathy, systemic lupus erythematosus, high risk for HIV infection, cirrhosis, liver tumor, sickle cell disease, solid organ transplantation, and drug interactions with antiretrovirals used for prevention or treatment of HIV infection); and 3) inclusion of new contraceptive methods, including new doses or formulations of combined oral contraceptives, contraceptive patches, vaginal rings, progestin-only pills, levonorgestrel intrauterine devices, and vaginal pH modulator. The recommendations in this report are intended to serve as a source of evidence-based clinical practice guidance for health care providers. The goals of these recommendations are to remove unnecessary medical barriers to accessing and using contraception and to support the provision of person-centered contraceptive counseling and services in a noncoercive manner. Health care providers should always consider the individual clinical circumstances of each person seeking contraceptive services. This report is not intended to be a substitute for professional medical advice for individual patients; when needed, patients should seek advice from their health care providers about contraceptive use., Competing Interests: All authors have completed and submitted the International Committee of Medical Journal Editors form for disclosure of potential conflicts of interest. No potential conflicts of interest were disclosed. To promote transparency, all meeting participants were asked to disclose potential conflicts of interest to CDC before the expert meeting and to report potential conflicts of interest during the introductory portion of the expert meeting. All potential conflicts of interest disclosed by meeting participants are listed. No participants were excluded from discussion based on potential conflicts of interest. CDC staff members who ultimately decided and developed these recommendations have no financial interests or other relationships with the manufacturers of commercial products, suppliers of commercial services, or commercial supporters relevant to these recommendations.

Patellofemoral arthroplasty (PFA) is emerging as an attractive alternative to total knee arthroplasty (TKA) for isolated patellofemoral-osteoarthritis (PF-OA) for selected patients. The success of PFA is highly dependent on patient selection. This intervention is still burdened with a higher rate of revisions and a lower survival rate than TKA when the indications or the surgical technique are not optimal. We highlight the indications and contraindications of PFA to obtain satisfying functional outcomes and survivorship. Preoperative clinical and radiological assessment is critical to determine the presence of PFA indications, the absence of contraindications and the necessity of any associated procedures, particularly for the tibial tubercle. The typical indications are patients with isolated symptomatic PF-OA, with trochlear dysplasia, when bone-on-bone Iwano 4 osteoarthritis is observed, without significant malalignment and with the absence of risk factors for developing progressive tibiofemoral-OA. The three main causes of isolated PF-OA are primary OA, trochlear dysplasia and posttraumatic OA following patellar fracture. Trochlear dysplasia is the preferred indication for PFA. Lack of experience with arthroplasty or realignment of the extensor mechanism is a relative contraindication to performing PFA., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 The Author(s).

Regional anesthesia has a strong role in minimizing post-operative pain, decreasing narcotic use and PONV, and, therefore, speeding discharge times. However, as with any procedure, regional anesthesia has both benefits and risks. It is important to identify the complications and contraindications related to regional anesthesia, which patient populations are at highest risk, and how to mitigate those risks to the greatest extent possible. Overall, significant complications secondary to regional anesthesia remain low. While a variety of different regional anesthesia techniques exist, complications tend to fall within 4 broad categories: block failure, bleeding/hematoma, neurological injury, and local anesthetic toxicity., (Copyright © 2023 Elsevier Inc.

Background: The effectiveness of compression therapy (CT) and the best compression modality choice are questioned in many clinical stages of chronic venous disease (CVD). This work aims to obtain information on indications, contraindications, and the best treatment option for CT in different clinical scenarios of CVD., Method: An online survey was made among members of the International Compression Club, experts in CT., Results: The experts apply CT in all clinical stages of CVD, even when evidence is missing. Regarding compression materials, experts use inelastic materials in the advanced stages of CVD and compression stockings in the early or chronic stages of CVD., Conclusion: The authors highlight the gap between experts' practical use of CT and evidence-based medicine results. They also suggested that, given the cost of randomized clinical trials aimed at specifying specific indications for different devices, artificial intelligence could be used for large-scale practice surveys in the future., Competing Interests: Declaration of conflicting interestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Cochlear implantation has emerged as a transformative intervention in addressing profound hearing loss, offering a paradigm shift in auditory rehabilitation for individuals with restricted auditory function. Throughout its history, the understanding of contraindications for cochlear implant (CI) surgery has evolved significantly. This review comprehensively analyzes the chronological advancements in the understanding of CI contraindications, examining studies conducted from historical timelines to the present. Recent research has revealed significant developments in the field, prompting a reevaluation of established criteria and resulting in expanded indications for CI. The chronological evolution of contraindications underscores the transformative nature of the field, offering potential improvements in outcomes and enhancing the quality of life for individuals with profound hearing loss. In conclusion, this narrative review emphasizes the dynamic nature of the field, where the reevaluation of contraindications has created new opportunities and broader indications for CI. The emerging prospects, including improved outcomes and enhanced quality of life, hold promise for individuals with profound hearing loss.

Background: Alpha-gal syndrome is an allergic condition in which individuals develop an immune-mediated hypersensitivity response when consuming red meat and its derived products. Its diagnosis is important in individuals undergoing cardiac surgery, as patients frequently require large doses of unfractionated heparin or the insertion of surgical implants, both of which are porcine or bovine in origin. There are currently no guidelines for heparin administration in alpha-gal patients, with even less knowledge regarding the long-term clinical implications of these patients after receiving bioprosthetic valve replacements or other prostheses., Case Presentation: We present the case of a 31-year-old male who underwent cardiac surgery in the setting of alpha-gal syndrome for a large atrial septal defect (ASD) and mitral valve prolapse (MVP). The patient continues to do well one year after undergoing a mitral valve repair, tricuspid valve repair and an ASD closure using bovine pericardium. He sustained no adverse reaction to the use of heparin products or the presence of a bovine pericardial patch. This rare case was managed by a multidisciplinary team consisting of cardiothoracic surgery, cardiac anesthesiology, and allergy/immunology that led to an optimal outcome despite the patient's pertinent allergic history., Conclusions: This case highlights that the use of bovine pericardium and porcine heparin to close septal defects in patients with milder forms of alpha-gal allergy can be considered if other options are not available. Further studies are warranted to investigate the long-term outcomes of such potential alpha-gal containing prostheses and heparin exposure and establish the optimal decision making algorithm and prophylactic regimen., (© 2024.

Whole-body electromyostimulation has proven to be a highly effective alternative to conventional resistance-type exercise training. However, due to adverse effects in the past, very extensive contraindications have been put in place for the commercial, non-medical WB-EMS market. Considering recent positive innovations e.g., federal regulation, mandatory trainer education, revised guidelines, and new scientific studies on WB-EMS application, we believe that a careful revision of the very restrictive contraindications on WB-EMS is needed. This applies all the more because many cohorts with limited options for conventional exercise have so far been excluded. During a first meeting of an evidence-based consensus process, stakeholders from various backgrounds (e.g., research, education, application) set the priorities for revising the contraindications. We decided to focus on four categories of absolute contraindications: "Arteriosclerosis, arterial circulation disorders", "Diabetes mellitus" (DM), "Tumor and cancer" (TC), "Neurologic diseases, neuronal disorders, epilepsy". Based on scientific studies, quality criteria, safety aspects and benefit/risk assessment of the category, DM and TC were moved to the relative contraindication catalogue, while arteriosclerosis/arterial circulation disorders and neurologic diseases/neuronal disorders/epilepsy were still considered as absolute contraindications. While missing evidence suggests maintaining the status of neurologic diseases/neuronal disorders as an absolute contraindication, the risk/benefit-ratio does not support the application of WB-EMS in people with arteriosclerosis/arterial circulation diseases. Despite these very cautious modifications, countries with less restrictive structures for non-medical WB-EMS should consider our approach critically before implementing the present revisions. Considering further the largely increased amount of WB-EMS trials we advice regular updates of the present contraindication list., Competing Interests: The authors declare the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest.

Malnutrition is a common condition among hospitalized patients and has an important impact on morbidity and mortality. Despite enteral nutrition being the preferred option for patients requiring artificial alimentation, parenteral nutrition (PN) can be required. This article emphasizes the importance of choosing the adequate vascular access based on the chosen PN. Furthermore, it reviews indications, contraindications and complications of PN.

Purpose: The research objective of this study is to use finite element analysis to investigate the impact of anterior cruciate ligament (ACL) injury on medial unicompartmental knee arthroplasty (UKA) and explore whether patients with ACL injuries can undergo UKA., Methods: Based on the morphology of the ACL, models of ACL with diameters ranging from 1 to 10mm are created. Finite element models of UKA include ACL absence and ACLs with different diameters. After creating a complete finite element model and validating it, four different types of loads are applied to the knee joint. Statistical analysis is conducted to assess the stress variations in the knee joint structure., Results: A total of 11 finite element models of UKA were established. Regarding the stress on the ACL, as the diameter of the ACL increased, when a vertical load of 750N was applied to the femur, combined with an anterior tibial load of 105N, the stress on the ACL increased from 2.61 MPa to 4.62 MPa, representing a 77.05% increase. Regarding the equivalent stress on the polyethylene gasket, a notable high stress change was observed. The stress on the gasket remained between 12.68 MPa and 14.33 MPa in all models. the stress on the gasket demonstrated a decreasing trend. The equivalent stress in the lateral meniscus and lateral femoral cartilage decreases, reducing from the maximum stress of 4.71 MPa to 2.61 MPa, with a mean value of 3.73 MPa. This represents a reduction of 44.72%, and the statistical significance is (P < 0.05). However, under the other three loads, there was no significant statistical significance (P > 0.05)., Conclusion: This study suggests that the integrity of the ACL plays a protective role in performing medial UKA. However, this protective effect is limited when performing medial UKA. When the knee joint only has varying degrees of ACL injury, even ACL rupture, and the remaining structures of the knee joint are intact with anterior-posterior stability in the knee joint, it should not be considered a contraindication for medial UKA., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2024 Ou et al.

A sedentary lifestyle is a significant cardiovascular risk factor and increases premature mortality. Engaging in routine physical activity (PA) provides a wide range of health benefits. Accordingly, physical inactivity must be identified and sedentary patients supported systematically to achieve recommended levels of PA. The level of PA can be assessed by taking patients' history and using specific tools. Support begins by assessing PA contraindications and patients' level of motivation to change their lifestyle. Patients are then encouraged to adopt a more active lifestyle through tailored advice, and if necessary, referred to specialists with expertise in exercise medicine. This article details the key aspects of accompanying sedentary patients, to help healthcare professionals integrate them into their practice., Competing Interests: Les auteurs n’ont déclaré aucun conflit d’intérêts en relation avec cet article.

The impact of energy on the thorax can lead to serial rib fractures, sternal fractures, the combination of both and to injury of intrathoracic organs depending on the type, localization and intensity. Sometimes this results in chest wall instability with severe impairment of the respiratory mechanics. In the last decade the importance of surgical chest wall reconstruction in cases of chest wall instability has greatly increased. The evidence for a surgical approach has in the meantime been supported by prospective randomized multicenter studies, multiple retrospective data analyses and meta-analyses based on these studies, including a Cochrane review. The assessment of form and severity of the trauma and the degree of impairment of the respiratory mechanism are the basis for a structured decision on an extended conservative or surgical reconstructive strategy as well as the timing, type and extent of the operation. The morbidity (rate of pneumonia, duration of intensive care unit stay and mechanical ventilation) and fatality can be reduced by a timely surgery within 72 h after trauma. In this article the already established and evidence-based algorithms for surgical chest wall reconstruction are discussed in the context of the current evidence., (© 2024.

The Impella 5.5 left ventricular assist device (LVAD) is typically placed in a hybrid operating room with fluoroscopic and echocardiographic guidance under general anesthesia. In this case report, we describe a patient with severe cardiopulmonary failure necessitating an Impella 5.5 as a bridge to heart/lung transplant. Here, we describe the successful placement of the Impella 5.5 with sedation and local anesthesia in order to avoid general anesthesia and the sequelae of positive pressure ventilation in a fragile patient. Impella placement was confirmed with transesophageal echocardiography. This case report demonstrates a novel strategy for placing the Impella 5.5 and, more importantly, opens the possibility to future prospective studies of this technique., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Background: Clinical pharmacists identified contraindications in two cases concerning the co-administration of cefoperazone and ambroxol hydrochloride injection, prompting a thorough investigation., Case Presentation: Clinically, two cases of contraindications for the co-administration of cefoperazone and ambroxol hydrochloride injection were discovered. After the intervention and analysis by clinical pharmacists, the possible reason could be the precipitation of free alkali due to the immediate administration of ambroxol after the infusion of cefoperazone. Clinical pharmacists suggested avoiding the co-administration of the two and recommended flushing the intravenous lines with 5% glucose injection or 0.9% sodium chloride injection during intravenous infusion to prevent direct drug interaction causing precipitation, thereby reducing the occurrence of adverse events. No adverse events occurred after the intervention, and no harm was caused to the patients., Conclusions: The co-administration of cefoperazone and ambroxol hydrochloride injection can lead to the precipitation of free alkali, posing a risk of adverse events. Clinical pharmacists' intervention could prevent this interaction. This practice has been shown to be effective, with no subsequent adverse events reported.

Background: Type A aortic dissection (TAAD) surgical management is still under debate. The purpose of this study was to demonstrate the feasibility and safety of the aortic valve-sparing root reconstruction (AVSR) procedure in 92 consecutive patients operated for TAAD, even when preoperative condition was severe (malperfusion, shock or both)., Methods: Our hospital database was reviewed to identify all patients who underwent an AVSR procedure for TAAD over 14 years. From May 2000 to June 2014, 92 consecutive patients were studied regarding to their preoperative condition., Results: Age (61±13 years) and logistic Euroscore (23.4±15.3%) as well as cross-clamping (113±39 min), cardiopulmonary bypass (142±49 min) and circulatory arrest (22±13 min) times were collected. Hospital mortality was 16.3%. Mean follow-up was complete for a mean period of 27.6 months. One patient had early reoperation for aortic insufficiency. Actuarial survival at 1 year was 82.5%. The analysis of each group showed comparable mortality and morbidity in between patients., Conclusions: Based upon our experience in the management of TAAD, a reimplantation procedure could be performed regardless preoperative malperfusion or shock, with an acceptable postoperative over mortality or morbidity. A word of caution should be brought to patients over 70 years old.

Idiopathic pulmonary fibrosis (IPF) is a globally prevalent, progressive disease with limited treatment options and poor prognosis. Because of its irreversible disease progression, IPF affects the quality and length of life of patients and imposes a significant burden on their families and social healthcare services. The use of the antifibrotic drugs pirfenidone and nintedanib can slow the progression of the disease to some extent, but it does not have a reverse effect on the prognosis. The option of lung transplantion is also limited owing to contraindications to transplantation, possible complications after transplantation, and the risk of death. Therefore, the discovery of new, effective treatment methods is an urgent need. Over recent years, various studies have been undertaken to investigate the relationship between interstitial pneumonia and lung cancer, suggesting that some immune checkpoints in IPF are similar to those in tumors. Immune checkpoints are a class of immunosuppressive molecules that are essential for maintaining autoimmune tolerance and regulating the duration and magnitude of immune responses in peripheral tissues. They can prevent normal tissues from being damaged and destroyed by the immune response. While current studies have focused on PD-1/PD-L1 and CTLA-4, PD-1/PD-L1 may be the only effective immune checkpoint IPF treatment. This review discusses the application of PD-1/PD-L1 checkpoint in IPF, with the aim of finding a new direction for IPF treatment., (© 2024. The Author(s).)

Heart transplantation (HTx) remains the last therapeutic resort for patients with advanced heart failure. The present work is a clinically focused review discussing current issues in heart transplantation. Several factors have been associated with the outcome of HTx, such as ABO and HLA compatibility, graft size, ischemic time, age, infections, and the cause of death, as well as imaging and laboratory tests. In 2018, UNOS changed the organ allocation policy for HTx. The aim of this change was to prioritize patients with a more severe clinical condition resulting in a reduction in mortality of people on the waiting list. Advanced heart failure and resistant angina are among the main indications of HTx, whereas active infection, peripheral vascular disease, malignancies, and increased body mass index (BMI) are important contraindications. The main complications of HTx include graft rejection, graft angiopathy, primary graft failure, infection, neoplasms, and retransplantation. Recent advances in the field of HTx include the first two porcine-to-human xenotransplantations, the inclusion of hepatitis C donors, donation after circulatory death, novel monitoring for acute cellular rejection and antibody-mediated rejection, and advances in donor heart preservation and transportation. Lastly, novel immunosuppression therapies such as daratumumab, belatacept, IL 6 directed therapy, and IgG endopeptidase have shown promising results.

Obstructive sleep apnea (OSA) is a common condition that can cause daytime or nocturnal symptoms with long-term impact on the patient's health. Various therapies and surgeries have been introduced over the years, and patient wishes and compliance are essential factors in the success of treatment. Drug-induced sleep endoscopy (DISE) is a procedure that assesses the opening and closing of the upper airway in real time. This article summarizes the indications and contraindications of DISE, with a review of sedation methods and the VOTE classification system, in order to facilitate the use of a common nomenclature based on a protocol applied at the CHUV., Competing Interests: Les auteurs n’ont déclaré aucun conflit d’intérêts en relation avec cet article.

Musculoskeletal ultrasound (MSUS) is characterized as the dynamic, real-time and continuous visualization, the quantitative and qualitative localization,the simple operation and the absence of use contraindication. As a tool for auxiliary examination, treatment, evaluation and research, in acupuncture and moxibustion, MSUS may improve the accuracy of acupoint location, guide the direction and depth of needle insertion, monitor the reactions of deqi , guarantee the safety of operation and quantify the effect evaluation. Hence, it may provide an objective basis for acupuncture and moxibustion research and be conductive to display the operation techniques of acupuncture and moxibustion by means of objective approaches such as imaging and data.

Objective: The purpose of this study is to examine how lateral wall collapse affects treatment outcomes for hypoglossal nerve stimulation (HNS) patients., Methods: Patients (n = 111) queried from a single surgeon's database of HNS cases were divided into groups based on their degree of oropharyngeal lateral wall collapse noted on drug-induced sleep endoscopy (DISE): Complete, Partial, None. For each group, apnea hypopnea index (AHI) reduction, Epworth Sleepiness Scale (ESS) score, stimulation voltage, average nightly usage, need for alternate device configuration/awake sleep endoscopy, and rate of surgical success were collected. Patients with Complete collapse were compared to those with Partial/None via Student's t-tests and Pearson's Chi-square test., Results: Of the 111 eligible patients, 45 had complete, 30 partial, and 36 had no lateral oropharyngeal wall collapse. There were no statistically significant differences found between the Complete and Partial/None groups in terms of age, BMI, sex, AHI (pre and post-op), ESS (pre and post-op), voltage, alternate device configuration, or nightly adherence. Notably, a significantly greater number of the Partial/None group had surgical success (84.84 % vs 66.67 %, p = 0.024)., Conclusions: Patients with Partial/None oropharyngeal collapse were significantly more likely than patients with Complete lateral wall collapse to see surgical success. There are many factors to weigh when assessing a patient's surgical candidacy, it is clear that complete lateral wall collapse at the level of the oropharynx is a negative predictor for success in HNS., (Copyright © 2023 Elsevier Inc.

Purpose: The authors report long-term results of the oral propranolol treatment protocol for periocular infantile hemangioma regardless of conventional indications., Methods: This is a retrospective study (2008-2018) on children with propranolol treatment protocol for periocular infantile hemangioma and last follow-up (FU) of ≥4 months after treatment and age of >24 months. After systemic evaluation, it was started with 0.5 and increased by 0.5 every 3 days to reach 2 mg/kg/day. If there was no good response, it would be gradually increased up to 3 mg/kg/day. Tapering (0.5 mg/kg/day every 4 weeks) was started when patients were on treatment for ≥6 months and ≥12 months old and there was no change in the infantile hemangioma size for ≥3 months. Rebound growth was based on the parents' report and would be treated by increasing the dose to at least 2 mg/kg/day for 3 months. FU was either in-person or via social media. Change in periocular infantile hemangioma size on the photos was scored by 3 masked observers (visual analog scale) and presented as excellent (≥50% reduction), good (1%-49%), fair (no change), and failure (enlarged)., Results: Forty-three patients were included. Orbital involvement was in 49%, ptosis in 58%, and risk of amblyopia in 63%. Mean treatment, tapering, and FU duration were 37, 13, and 74 months, respectively. Mean age at presentation, start of propranolol treatment protocol, tapering, stop, and last FU were 1.5, 5, 29, 42, and 78 months, respectively. Twenty-seven patients received 2, seven 2.5, and nine 3 mg/kg/day. Mean visual analog scale significantly increased from 43% (FU1) to 92% (last FU) when 97.6% of patients showed an excellent response. The remaining skin lesions were observed in 35%. No side effect was reported., Conclusions: Long-term results of the propranolol treatment protocol for periocular infantile hemangioma showed an excellent response in 97.6% of patients with no side effects. A residual skin lesion was observed in 1/3 of the patient., Competing Interests: The authors have no financial or conflicts of interest to disclose., (Copyright © 2023 The American Society of Ophthalmic Plastic and Reconstructive Surgery, Inc.)

Purpose: To evaluate the impact of pre-transjugular intrahepatic portosystemic shunt (TIPS) hepatic encephalopathy (HE) on developing post-TIPS HE., Materials and Methods: In this retrospective, single center observational study, all patients who underwent successful TIPS placement between January 2005 and May 2020 with data pertaining to HE in their chart were included. Patient demographics and procedural details were recorded. Clinical outcomes post-TIPS, were collected and compared across patients with and without pre-TIPS HE., Results: Of 326 included patients, 159 (159/326, 48.8%) had a history of pre-TIPS HE. In total those without a history of HE were more likely to develop HE during follow up (136 (136/167, 81.4%) vs 107 (107/159, 67.3%), p = 0.001). When evaluating for predictors of developing HE within 3 months of TIPS placement, no significant variables were found on logistic regression, including prior history of HE (HR 1.16 (95% CI 0.73-1.84), p = 0.529). Univariate and multivariate regression analysis, however, showed that a history of HE was predictive of developing HE at any point in the follow-up period (p = 0.002 and p = 0.008, respectively). However, on Kaplan-Meier analysis no significant difference in the development of HE (p = 0.574) or hospital admission for HE (p = 0.554) post-TIPS was seen between patients with and without pre-TIPS HE. Additionally, there was no difference in 3-month survival (p = 0.412) or overall survival post-TIPS survival (p = 0.798)., Conclusion: Pre-TIPS HE did not predict the development of HE within 3 months of TIPS. Outcomes such as hospital admission and survivability were not different between patients with and without prior HE., (© 2023.

Introduction: There now exist preventive and curative treatments available for both early and advanced stages of COVID-19 management., Current Knowledge: Antibiotics have no place in the initial therapeutic management of Sars-Cov-2 pneumonia. On the other hand, corticosteroids are recommended for patients requiring oxygen therapy≥2L/min. According to the latest recommendations, nirmatrelvir/ritonavir is indicated as an early treatment for adults not requiring oxygen therapy but at high risk of developing a severe form of COVID-19. In case of contraindication, remdesivir is an alternative therapy., Perspectives: Although there is no indication for convalescent plasma outside of clinical trials, it seems promising for immunocompromised patients, particularly those with B lymphopenia. It is noteworthy that currently, with the predominance of the Omicron XBB.1.5 variant, monoclonal antibodies are no longer recommended as therapy except for sotrovimab, which still has partial efficacy and could be considered after expert opinion as salvage therapy in a previously well-established program., Conclusion: Despite the evolution of variants, antivirals still appear to have activity and remain the first-line treatment for patients, in addition to vaccination., (Copyright © 2023 SPLF.

Extracorporeal life support (ECLS), in particular veno-arterial extracorporeal membrane oxygenation, has emerged as a potentially life-saving treatment modality in patients presenting with pulmonary hypertension and right heart failure refractory to conventional treatment. Used mainly as a bridge to lung transplantation, ECLS is also being used occasionally as a bridge to recovery in patients with treatable causes of right heart failure. This review article describes indications, contraindications, techniques, and outcomes of the use of ECLS in patients with PH, focusing on practical aspects in the management of such patients., Competing Interests: M.M.H. has received fees for lectures and/or consultations from Acceleron, Actelion, AOP Health, Bayer, Ferrer, GSK, Janssen, MSD, all outside the present work., (Thieme.

An intensive conservative treatment that exhausts all treatment options should fundamentally be carried out before every surgical intervention in the region of the spinal column. The therapeutic measures are determined by the extent of the cervical or lumbar syndrome. As a rule, in cases of local complaints symptomatic measures with physiotherapy or digital healthcare applications are indicated. In cases of referred cervical and lumbar syndromes targeted injections can be employed. Before targeted injection treatment a detailed orthopedic clarification with respect to the intensity of local, radicular or pseudoradicular complaints must be carried out. When carrying out minimally invasive injection treatment specific prerequisites with respect to spatial, personnel and technical conditions must be fulfilled. The indications and contraindications must be strictly controlled., (© 2023. The Author(s), under exclusive licence to Springer Medizin Verlag GmbH, ein Teil von Springer Nature.)

Active infections in recipients are considered an absolute contraindication to liver transplantation due to the risk of severe disease caused by the required immunosuppression. Even though viral infections, such as Influenza A, have been treated in liver transplant patients both in the immediate and late postoperative period with favorable outcomes, no cases of prediagnosed Influenza A have been described in which the decision to proceed with the indication had to be made. In certain viral infections, like Influenza A, the paucisymptomatic state and the availability of appropriate treatment could open the door to performing liver transplants with positive results., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 Elsevier Inc.

Introduction: The prevalence of molar incisor hypomineralisation (MIH), the degree of severity of experienced molars, their medium-term survival rate are factors that have reintroduced the decision to extract first permanent molars, forced extractions or chosen therapeutic option., Material and Method: The author summarizes pedodontic and orthodontic clinical studies in the management of patients with compromised first permanent molars in order to analyze the consequences of single or multiple extractions of these teeth., Results: Firstly, the consequences of extractions of the first permanent molars in the absence of malocclusion are studied. The goal is the establishment of all the teeth without orthodontic treatment. The impact of the age at which the extraction is practiced is a key factor. In a second step, extractions of first permanent molars in the presence of orthodontic anomalies are analyzed to define the optimal therapeutic strategies, the precautions during these treatments, the contraindications. Consultation and good coordination between the generalist dentist / pediatric dentist and orthodontist are the key factors for stable and functional end-of-treatment results and optimized treatment duration., Discussion: Clinical experience and knowledge make it possible to properly select patients qualified for these therapies who obtain multidisciplinary planning and good biomechanical control., Conclusion: By bringing together optimal decision-making conditions, extraction is a therapeutic option that often proves to be superior to a restorative option in providing our patients with the greatest long-term service.

Physical Activity: TOOLS FOR CUSTOMIZED ASSESSMENT AND PRESCRIPTION. Physical activity is a significant part of the global therapeutic care of chronic diseases. It also effectively contributes to prevent complications and relapses of these diseases. Thus, the prescription of physical activity must find its place in physician everyday practice. However, this prescription remains too unusual due to a number of obstacles. Simple, practical tools have been developed to facilitate its implementation, including a contraindications sheet, an effort level prescription, a functional phenotype table, a general and specific indications sheet, and a physical activity prescription template. These tools for prescribing physical activity should enable it to be integrated more systematically and as early as possible into patient care. Following a decision tree, a medical assessment can be carried out to take into account the particular conditions of each patient and propose a more detailed medical prescription., Competing Interests: L’auteure déclare des interventions ponctuelles pour le Réseau français villes-santé, le Comité régional d’éducation pour la santé Provence-Alpes-Côte d’Azur (CRES), la Mutualité française et avoir été prise en charge, à l’occasion d’un déplacement pour un congrès, par le Centre national de la fonction publique territoriale.

Liver transplantation (LT) is a life-saving therapeutic modality for patients with various advanced liver diseases. It is crucial to identify that the patient's illness is sufficiently advanced and unlikely to improve with medical management to justify the need for transplantation. At the same time, it is crucial to identify patients with comorbidities and far advanced disease that would result in an unacceptable outcome after LT. Specific care also is required before deciding on LT in the elderly, acute on chronic liver disease, patients with comorbidities, and hepatocellular carcinoma. Transplantation needs to be timed appropriately to avoid unnecessary LT and ensure that the decision is not left too late to avoid losing the patient without a transplant. Also, important is the decision as to when not to transplant. The current review explores some of these issues of contraindications and ineligibility for LT., (© 2023 Indian National Association for Study of the Liver. Published by Elsevier B.V.)
