Many questions are raised, and challenges faced in the new era of (intranasal) bovine respiratory disease complex vaccination. An increase in vaccination rate is expected, due to its positive impact on cattle health, reduction of antimicrobial use and economic factors. However, engagement of farmers and veterinarians with regard to vaccination is often affected by limitations, resulting in the development of barriers to vaccination, but also opportunities to overcome these. The objective of the report is to provide practical recommendations and a consensus on best practises for BRDC vaccination, addressing barriers faced by veterinarians and farmers. The report combines an evidence review with expert opinions and includes discussions on different vaccination approaches, such as intranasal and systemic protocols. As result of the discussions, several barriers to BRDC vaccination were identified, including a lack of knowledge or visibility of the disease\'s impact, the preference for blanket antibiotic use over vaccination, resistance to change, the need for visible success, uncertainty about the best time to vaccinate, and concerns about adverse reactions and vaccine efficacy in the presence of maternal antibodies. While these barriers seem substantial, they provide opportunities for the veterinary sector. Indeed, veterinarians are encouraged to use the argumentation presented, along with local case studies and diagnostic testing to highlight the impact of disease, while conducting calf health audits, ensuring expectations are managed to achieve visible success. Overall, this consensus paper aims to provide practical recommendations and support for veterinarians and farmers to overcome barriers and increase BRDC vaccination rates in cattle.

BACKGROUND: Alopecia areata (AA) is a chronic disease with an unpredictable course and can have a severe psychological impact on an individual.
OBJECTIVE: To provide evidence and consensus-based statements regarding the treatment of patients with AA in Korea.
METHODS: We searched for relevant studies from inception to May 2021 regarding the systemic treatment of AA. Evidence-based recommendations were also prepared. The evidence for each statement was graded and classified according to the strength of the recommendations. Hair experts from the Korean Hair Research Society (KHRS) voted on the statement, and an agreement of 75% or greater was considered as having reached consensus.
RESULTS: Current evidence supports the efficacy of systemic corticosteroids, oral cyclosporine monotherapy or combination with systemic corticosteroids, and oral Janus kinase inhibitors in severe AA patients. Systemic steroids may be considered for pediatric patients with severe AA. A consensus was achieved in three out of nine (33.3%), and one out of three (33.3%) statements pertaining to systemic treatment in adult and pediatric AA, respectively.
CONCLUSIONS: The present study produced up-to-date, evidence-based treatment guidelines for AA associated with the consensus obtained by experts based on the Korean healthcare system.

Thrombolytic therapy has been the mainstay for patients with pulmonary embolism (PE). Despite being linked to a higher risk of significant bleeding, clinical trials demonstrate that thrombolytic therapy should be used in patients with moderate to high-risk PE, in addition to hemodynamic instability symptoms. This prevents the progression of right heart failure and impending hemodynamic collapse. Diagnosing PE can be challenging due to the variety of presentations; therefore, guidelines and scoring systems have been established to guide physicians to correctly identify and manage the condition. Traditionally, systemic thrombolysis has been utilized to lyse the emboli in PE. However, newer techniques for thrombolysis have been developed, such as endovascular ultrasound-assisted catheter-directed thrombolysis for massive and intermediate-high submassive risk groups. Additional newer techniques explored are the use of extracorporeal membrane oxygenation, direct aspiration, or fragmentation with aspiration. Because of the constantly changing therapeutic options and the scarcity of randomized controlled trials, choosing the best course of treatment for a given patient may be difficult. To help, the Pulmonary Embolism Reaction Team is a multidisciplinary, rapid response team that has been developed and is used at many institutions. Hence to bridge the knowledge gap, our review highlights various indications of thrombolysis in addition to the recent advances and management guidelines.

Systemic lupus erythematosus (SLE) is a heterogeneous autoimmune disease that represents a prodigious challenge of diagnosis and treatment. In 2019, under the leadership of the Chinese Rheumatology Association, a multidisciplinary guideline development group was established to develop an evidence-based diagnosis and treatment guideline for patients with SLE in PR China. The Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach was used to evaluate the quality of evidence and the strength of recommendations. The guideline was reported following the Reporting Items for Practice Guidelines in Healthcare (RIGHT) checklist. In this guideline, we provided recommendations for SLE classification criteria, disease activity monitoring and assessment, medication administration and considerations for SLE patients with organs and systems involved, and management of special populations such as SLE patients in the setting of pregnancy. This guideline serves as an evidence-based tool for Chinese clinicians to diagnose and treat patients with SLE.

Uveitis is a sight-threatening disease that can be associated with many different etiologies. Successful treatment of uveitis relies on accurate diagnosis and prompt efficient therapy. History taking, physical and ocular examinations, systemic evaluations, and response to treatment provide crucial information to differentiate possible etiologies involved in the pathophysiology of intraocular inflammation. This article provides recommendations for a step-wise approach to patients with uveitis in Taiwan based on an expert meeting and consensus. Systemic evaluations for uveitis should be performed step-by-step and include investigation of patients\' general systemic conditions, ruling out infectious etiologies, and obtaining evidential biomarkers to diagnose a specific disease entity.

UNASSIGNED: Psoriasis is a common inflammatory disease with significant comorbidities, and regardless of its extent, it affects the patients\' quality of life. The various modalities of treating psoriasis comprise topical or systemic medications, phototherapy, and an array of biologic agents. There is a lack of Indian recommendations on the management of psoriasis with these different modalities and challenges faced by the clinicians in day-to-day practice.
UNASSIGNED: To develop India-specific consensus for systemic management of patients with moderate-to-severe psoriasis.
UNASSIGNED: A panel of dermatology experts, based on the evidence and international recommendations, coupled with their own clinical experience, developed recommendations for systemic management of patients with moderate-to-severe psoriasis.
UNASSIGNED: These recommendations are meant to provide guidance in terms of choice of systemic therapies, dosing, effectiveness, and safety. It also addresses clinical challenges that may be experienced during psoriasis management.

The Addressing Lupus Pillars for Health Advancement (ALPHA) Project is a global consensus effort to identify, prioritise and address top barriers in lupus impacting diagnosis, care, treatment and research. To conduct this process, the ALPHA Project convened a multistakeholder Global Advisory Committee (GAC) of lupus experts and collected input from global audiences, including patients. In phase I, the ALPHA Project used expert interviews and a global survey of lupus experts to identify and categorise barriers into three overarching pillars: drug development, clinical care and access to care. In phase II, reported here, the GAC developed recommended actionable solutions to address these previously identified barriers through an in-person stakeholder meeting, followed by a two-round scoring process. Recommendations were assessed for feasibility, impact and timeline for implementation (FIT), where potential FIT component values were between 1 and 3 and total scores were between 3 and 9. Higher scores represented higher achievability based on the composite of the three criteria. Simplifying and standardising outcomes measures, including steroid sparing as an outcome (drug development) and defining the lupus spectrum (clinical care) ranked as the highest two priority solutions during the GAC meeting and received high FIT scores (7.67 and 7.44, respectively). Leveraging social media (access to care) received the highest FIT score across all pillars (7.86). Cross-cutting themes of many solutions include leveraging digital technology and applying specific considerations for special populations, including paediatrics. Implementing the recommendations to address key barriers to drug development, clinical care and access to care is essential to improving the quality of life of adults and children with lupus. Multistakeholder collaboration and guidance across existing efforts globally is warranted.

Hydroxychloroquine (HCQ) retinal toxicity is an ongoing concern for rheumatologists. The revised 2016 American Academy of Ophthalmology (AAO) guidelines created controversy regarding the correct dosing and evaluation of HCQ toxicity. The current study was initiated to further understand rheumatologists\' practices regarding HCQ.
A questionnaire-based survey was distributed electronically to rheumatologists. We collected information on HCQ dosing, clinical decision-making processes, familiarity with the AAO 2016 guidelines, and perceived disparities between the AAO 2016 guidelines and rheumatological clinical practice.
78 rheumatologists completed the survey (49% from USA, 90% academic practices, 82% self-identified as lupus experts). Only lupus expert (n=64) data were included in subsequent analysis. The mean cohort size was 747 (50-6571), a total cohort 45 612 patients. HCQ was prescribed to >75% of patients with SLE by 81.3% of SLE experts, with routine counselling about ophthalmic risks. The typical dose of HCQ used was 200-400 mg/day. 17% of rheumatologists use doses up to 600 mg/day, while 6.2% use up to 6.5 mg/kg/day. HCQ adherence is routinely assessed. 479 cases of HCQ retinal toxicity (1.05%) and 9 cases of HCQ-associated blindness (1.8 per 10 000 patients) were reported. 89.1% of respondents reported familiarity with the AAO guidelines. Those aware of the guidelines cited limited dosing options (54.7%), lack of supporting evidence (57.8%) and low patient adherence (43.8%) as obstacles to greater implementation of the guidelines.
These data suggest that HCQ toxicity and blindness are rare in patients with SLE. Rheumatologists treating patients with SLE are aware of the guidelines and appreciate the importance of partnering with ophthalmologists in preventing retinal toxicity.

The management of hepatocellular carcinoma (HCC) has become ever more demanding. To evaluate the available evidence and to give clinicians the best guidance, all major hepatology societies have developed guidelines for HCC. Recently, updated versions have been published by the American, the Asian Pacific, and the European societies. This article presents a comparison of these three guidelines summarising both common ground and differences. Moreover, it highlights areas of ongoing research which will make yet another round of updates of the guidelines necessary in the near future.

BACKGROUND: Psoriasis is a common chronic skin condition that is prevalent worldwide. Despite the numerous treatment options available, discrepancies exist between international guidelines. Areas covered: This review aims to evaluate the current international guidelines for the systemic treatment of psoriasis and psoriatic arthritis. Expert commentary: Most guidelines are unanimous on medication dosing and laboratory monitoring. However, even the most up-to-date guidelines do not include many of the new biologic medications. Guidelines will require frequent updates to include the newer treatments and will soon need to state a recommendation on the use of biosimilars.
