Current treatment landscape of HR+/HER2− advanced breast cancer in the Nordics: a modified Delphi study

Background This Delphi study aimed to assess current perspectives on hormone receptor-positive/human epidermal growth factor receptor 2-negative(HR+/HER2−) advanced breast cancer (aBC) treatment strategies across the Nordics, and to establish where consensus exists across the Nordics on HR+/HER2− aBC treatment. Material and methods A modified, three-round Delphi method was followed. A steering committee was appointed for study coordination, panellist selection, and questionnaire development. The questionnaires covered relevant topics on HR+/HER2− aBC treatment: treatment patterns in different lines of therapy (first [1L], second [2L], and third [3L]), oligometastatic disease, de novo aBC, brain metastases, age as influential factor, visceral crisis, radiotherapy, diagnostics, and clinical guidelines. Both open and closed-ended questions were included. Consensus was defined as at least 70% agreement. Results In total, 28 experienced BC oncologists participated in the study from all five Nordic countries. Overall, topics reaching consensus included: preferred treatment approach in 1L and 2L therapy, treatment of oligometastatic disease, visceral crisis, brain metastases, and age-related treatment considerations. No consensus was reached for 3L therapy and local treatment for primary tumour in de novo aBC. Endocrine therapy (ET) combined with a cyclin-dependent kinase (CDK)4/6 inhibitor was the treatment of choice for 1L and 2L therapy. Treatment patterns in clinical practice did not always follow recommendations in current Nordic guidelines, as seen in the case of recently approved treatments. Discussion ET in combination with a CDK4/6 inhibitor is the preferred frontline treatment for HR+/HER2− aBC in the Nordics. The observed discrepancy between current guidelines and clinical practice could be due to differences in the reimbursement of novel treatments in the Nordics. Collaborative research efforts are warranted for topics that lack consensus.

Autonomic dysreflexia: Current pharmacologic management.

Autonomic dysreflexia (AD) is a frequent complication of spinal cord injury (SCI), though current clinical practice patterns for medication management of this condition are unknown. Correspondingly, it is unclear if national differences in practice patterns exist. To determine trends in current pharmacologic management of AD throughout the Americas. International survey of current physician practice patterns. Academic medical center. Sixty physicians managing patients with SCI and prescribing medications to manage AD. Not applicable. Presence of a formal pharmacologic AD management protocol, first- and second-line medications, patient characteristics influencing pharmacologic management. The majority of physicians (69%) had a formal AD management protocol for inpatient care, with nitroglycerin ointment (82%) being the most common first-line medication. Strong national differences existed regarding the use of nitroglycerin ointment, with 98% of U.S.-based physicians using this as first-line medication and 0% of physicians in Canada or Latin America using this due to recent lack of medication availability. Only 67% of physicians had a preferred second-line medication, with preferences split between hydralazine (48%) and nifedipine (28%). A systolic blood pressure threshold for pharmacologic management was used by 56% of physicians, wheres 26% considered neurological level of injury in decisions to use medications for AD. Heart rate was used by only 5% of physicians in their decision to manage AD with medications. As of 2023, U.S.-based physicians caring for individuals with SCI largely have formal inpatient protocols in place for medication management of AD, with nearly all relying on nitroglycerin ointment as their first-line medication. In areas outside of the United States where nitroglycerin ointment is unavailable, pharmacologic practice patterns significantly differ.

Current Advances in Genetic Testing for Spinal Muscular Atrophy.

Spinal muscular atrophy (SMA) is one of the most common genetic disorders worldwide, and genetic testing plays a key role in its diagnosis and prevention. The last decade has seen a continuous flow of new methods for SMA genetic testing that, along with traditional approaches, have affected clinical practice patterns to some degree. Targeting different application scenarios and selecting the appropriate technique for genetic testing have become priorities for optimizing the clinical pathway for SMA. In this review, we summarize the latest technological innovations in genetic testing for SMA, including MassArray®, digital PCR (dPCR), next-generation sequencing (NGS), and third-generation sequencing (TGS). Implementation recommendations for rationally choosing different technical strategies in the tertiary prevention of SMA are also explored.

A National Survey on the Clinical Practice Patterns of Korean Medicine Doctors for Attention Deficit Hyperactivity Disorder (ADHD) in Children and Adolescents.

To alleviate the symptoms of attention deficit/hyperactivity disorder (ADHD) in children and reduce the side effects of psychostimulants, parents are opting for complementary and alternative medicine as a therapeutic option. Korean medicine (KM) has been used by Korean medicine doctors (KMDs) to treat ADHD with herbal medication and acupuncture. This study aimed to conduct a cross-sectional survey on the clinical practice patterns of KM for ADHD in children targeting KMDs. The questionnaire included aspects related to patient characteristics, diagnosis, treatment modalities, and perceptions regarding KM. Questionnaires were distributed to all KMDs via e-mail, and the online surveys were conducted from 1 to 15 February 2023. A total 2.1% of KMDs (n = 537/25,574) completed the survey. The predominant diagnostic pattern identification employed was "depressed liver qi transforming into fire" (19.8%). Herbal medicine (HM) was the most common treatment (44.2%). The most frequently used HM prescriptions were Ondam-tang (16.9%), Eokgan-san (15.7%), and Sihogayonggolmoryeo-tang (14.4%). KMDs recognized HM as the most effective among the KM treatments (54.3%). The results of this study elucidate the current clinical practice patterns of KM for ADHD. Based on these findings, a treatment protocol can be developed to provide optimized KM treatment services to patients with ADHD.

Surgical Management of the Axilla in HR+/HER2- Breast Cancer in the Z1071 Era: A Propensity Score-Matched Analysis of the National Cancer Database.

Axillary management varies between sentinel lymph node biopsy (SLNB) and axillary lymph node dissection (ALND) for patients with clinical N1 (cN1), hormone receptor-positive (HR+), humanepidermal growth factor receptor 2 (HER2)/neu-negative (HER2-), infiltrative ductal carcinoma (IDC) who achieve a complete clinical response (cCR) to neoadjuvant systemic therapy (NAST). This study sought to evaluate clinical practice patterns and survival outcomes of SLNB versus ALND in this patient subset. Patients with cN1, HR+/HER2-, unilateral IDC demonstrating a cCR to NAST were identified from the 2012-2017 National Cancer Database (NCDB) and stratified based on final axillary surgery management (SLNB vs ALND). After propensity score-matching, overall survival (OS) was compared using a Kaplan-Meier analysis, and significant OS predictors were identified using Cox regression. Of the 1676 patients selected for this study, 593 (35.4%) underwent SLNB and 1083 (64.6%) underwent ALND. Use of SLNB increased by 28 % between 2012 and 2017. Among a total of 584 matched patients, 461 matched ypN0 patients, and 108 matched ypN+ patients, mean OS did not differ between SLNB and ALND (all patients [92.1 ± 0.8 vs 90.2 ± 1.0 months; p = 0.157], ypN0 patients [92.4 ± 0.8 vs 89.9 ± 0.9months; p = 0.105], ypN+ patients [83.5 ± 2.3 vs 91.7 ± 2.7 months; p ± 0.963). Cox regression identified age, Charlson score, clinical T stage, and pathologic nodal status as significant predictors of OS. The final surgical management strategy used for cN1, HR+/HER2- IDC patients who achieved a cCR to NAST did not have a significant impact on survival outcomes in this analysis. Potential opportunities for de-escalation of axillary management among this patient subset exist, and validation studies are needed.

Clinical Practice Patterns and Evidence-Based Medicine in Rhinoplasty: A 10-Year Review of Continuous Certification Tracer Data from the American Board of Plastic Surgery.

The American Board of Plastic Surgery (ABPS) has collected data on cosmetic surgery from member surgeons since 2003. These data offer valuable information on national trends in clinical practice. The present study was performed to analyze trends in rhinoplasty over the last decade. Tracer data were compared between two cohorts 2012-2016 (early cohort "EC") and 2017-2021 (recent cohort "RC"). Data included patient demographics and surgical techniques. Results were considered in the context of current EBM-based guidance in the plastic surgery literature. Data from 730 rhinoplasties (270 EC and 460 RC) were analyzed. The median age was 30years, and the most common patient concern was the nasal dorsum (79%). In the RC group, fewer patients voiced concerns about tip projection (58% vs 43%, p = 0.0002) and more complained of functional airway problems (38% vs 49%, p = 0.004). An open approach was most common (83%). Septoplasty (47% vs 52%, p = 0.005), caudal septum repositioning (14% vs 23%, p = 0.002), and tip rotation maneuvers (32% vs 49%, p < 0.0001) became more popular. There was also an increase in the use of spreader grafts (35% vs 45%, p = 0.01) and columellar strut grafts (42% vs 50%, p = 0.04), while there has been a decrease in alar base resection (17% vs 10%, p = 0.007) and non-cartilaginous dorsum/radix augmentation (9% vs 4%, p = 0.02). ABPS tracer data provide an excellent resource for the objective assessment of procedures in plastic surgery. The present study is the first to highlight evolving trends in rhinoplasty over the last 10years. This journal requires that authors assign a level of evidence to each article.

Paramagnetic rim sign in multiple sclerosis

To date, there is no accepted highly specific pattern for the detection of multiple sclerosis. Correct diagnosis is particularly difficult in situations where an atypical clinical picture of the disease is observed or nonstandard neuroimaging patterns are detected. Therefore, the scientific community has high hopes for the discovery of new markers that will allow clarification of the diagnosis in controversial cases. Currently, there is a lot of research focused on the study of an additional diagnostic MRI pattern – a sign of a paramagnetic rim. This symptom is associated with chronic smoldering central nervous system (CNS) lesions, is more commonly seen in young males, is found primarily in the periventricular region, and is also a promising predictor of disability and cognitive impairment. There is evidence that it is present in earlier stages of disease in “fresh” lesions of the CNS. However, further studies are needed to use this diagnostic MRI pattern in clinical practice.

Practice patterns of adjuvant radiotherapy in women with stage I to II endometrial carcinoma: a real-world multi-institutional analysis in China

BackgroundThis study aimed to report clinical practice patterns of postoperative radiotherapy for stage I to II endometrial carcinoma (EC) patients treated in 13 Chinese medical centers.MethodsWe included early stage EC patients treated by hysterectomy and adjuvant RT between 2003 and 2017 from 13 institutions. Patients were classified into 4 risk groups based on ESMO-ESGO-ESTRO recommendations (2014).ResultsA total of 1,227 cases were analyzed. Along the 15 years of the study, an increasing tendency was found towards administration for vaginal brachytherapy (VBT) alone, while the proportion of external beam pelvic radiotherapy (EBRT) alone remained stable in the corresponding period. When radiation modalities were stratified by risk groups, proportion of VBT alone significantly increased in all risk groups. The higher the risk, the later VBT became the main adjuvant treatment modality. However, EBRT alone or with VBT remained the main adjuvant method for high-risk patients.There were 13 dose-fractionation schemes for VBT alone with the scheme of 30 Gy in 6 fractions prescribed at 0.5cm under the vaginal mucosa accounting for most. There were 17 schemes for VBT boost and the most common schedule was 10 Gy in 2 fractions. The upper 3–5cm part of vagina was the most frequent target. 89.6% of the practitioners performed two-dimensional VBT technique. The median dose for EBRT was 50 Gy. From 2003 to 2017, conventional radiotherapy was gradually replaced by three-dimensional conformal radiotherapy modality and intensity modulated radiotherapy.ConclusionWe report a significant shift from EBRT to VBT alone for high-intermediate-risk, intermediate-risk and low-risk EC patients from 2003 to 2017 while EBRT remained the main radiation modality for high-risk early stage patients. There has been remarkable heterogeneity among VBT dose fractionation schedules across China.Trial registrationThe clinical trial ID was ChiCTR-PRC-17010712. It was authorized by the Institutional Review Board of Peking Union Medical College Hospital (N0. S-K139).

The Management of Acardiac Twinning: Twin Reverse Arterial Perfusion Sequence – An International Survey

Introduction: The optimal approach and therapy method for the acardiac twin with a reverse arterial perfusion sequence has not yet been established. The aim of this study was to determine the clinical practice patterns among international fetal therapy units in their management of these cases. Methods: A survey was sent to fetal centers across the world via email between December 2020 and December 2021. Results: Responses were obtained from 77% contacted centers. The most frequent ultrasound variables used in the evaluation of twin reverse arterial perfusion sequence include echocardiographic assessment of the pump twin and umbilical artery Doppler waveforms in the acardiac and pump twins, in 90% and 80% of the centers, respectively. Most centers in Europe and Latin America propose an in utero intervention in all cases. Most centers in Europe and Latin America prefer interstitial laser ablation, whereas radiofrequency ablation (RFA) is preferred in North America. The earliest gestational age for an intervention is on mean 13 weeks in Europe, which is earlier than the other geographic areas (p = 0.001). Conclusions: Most centers agreed that antenatal evaluation should include echocardiography along with the UA Doppler waveform measurements, and the most frequently used interventions were interstitial laser ablation or RFA at a median between 14 and 26 weeks.

Perceptions of and Practices for the Management of Constipation: Results of a Korean National Survey.

Although guidelines exist regarding the evaluation and management of patients with chronic constipation (CC), little is known about real-world clinical practice patterns. This study aimed to evaluate the various practices used to manage CC patients in various clinical settings in South Korea. A nationwide web-based survey was conducted, randomly selecting gastroenterologists and non-gastroenterologists. The 25-item questionnaire included physicians' perceptions and practices regarding the available options for diagnosing and managing CC patients in Korea. The study participants comprised 193 physicians (86 gastroenterologists, 44.6%) involved in the clinical management of CC patients. The mean clinical experience was 12 years. Only 21 of 193 respondents (10.9%) used the Rome criteria when diagnosing CC. The Bristol Stool Form Scale was used by 29% of the respondents (56/193), while the digital rectal examination was performed by 11.9% of the respondents (23/193). Laboratory testing and colonoscopies were performed more frequently by gastroenterologists than by non-gastroenterologists (both p=0.001). Physiologic testing was used more frequently by gastroenterologists (p=0.046), physicians at teaching hospitals, and physicians with clinical experience ≤10 years (both p<0.05). There were also significant differences in the preference for laxatives depending on the type of hospital. There were discrepancies in the diagnosis and management of CC patients depending on the clinical setting. The utilization rates of the Bristol Stool Form Scale and digital rectal examination by physicians are low in real-world clinical practice. These results imply the need for better and more practical training of physicians in the assessment and management of CC.

Dry eye clinical practice patterns of UK optometrists

PurposeIn light of the increased roles of optometrists working in primary care in the UK, this research study aimed to gain an insight into perceptions of dry eye disease (DED), knowledge and confidence in diagnosis and management, and satisfaction with currently available treatment options. MethodsLinks to an online survey were distributed to optometrists across the UK via optometry websites newsletters, conferences, and local optical committee data bases, between October 2021 and July 2022. The anonymous questionnaire contained a variety of question types including multiple choice, likert-type scale, and free text questions. ResultsThe survey was completed by 131 optometrists, with a broad range of experience, who reported examining 33.3 ± 31.0 dry eye patients per month. Forty-eight percent of respondents were involved in the provision of an extended service. Fluorescein tear breakup time, corneal fluorescein staining, and anterior lid assessment were the most used clinical procedures, both for diagnosis and monitoring purposes. Sixty percent of respondents reported that they believed their patients were satisfied/managed with artificial tear alone, with the availability of a preservative free option being the top consideration, particularly with increasing severity. Of the 18.7% of respondents who held Independent prescriber status, 68% felt this had widened their ability to diagnose and treat DED. This was evidenced by an increase in steroid recommendation for moderate and severe disease. ConclusionsAlthough dry eye disease was perceived to be an important condition, opinions varied widely regarding knowledge and confidence in diagnosis and management. Involvement in an extended service did not alter patient management. However, an increase in therapeutic management and the employment of a stepwise approach to management has been identified.

Characterizing Persons With HIV/HCV Coinfection Who Remain Untreated for Hepatitis C at Four HIV Clinics in Connecticut (CT): Role of Multiple Overlapping Barriers at the Individual and Clinic System Levels.

Introduction. Direct-acting antiviral medications have made hepatitis C virus (HCV) cure possible for >95% of persons with chronic HCV infection, including those coinfected with HIV. Achieving strategic HCV elimination targets requires an understanding of system, provider, and patient-level barriers to treatment. We explored such barriers among persons with HIV/HCV coinfection who remained untreated for HCV. Methods. Among four primary care HIV clinics in CT with high rates of HCV cure, 25 patients with HIV/HCV coinfection were eligible (no HCV treatment as of March 31, 2021). We conducted retrospective chart reviews of demographics, clinical practice patterns, patient-specific issues such as housing, transportation, food security, and presence of mental health and substance use problems. Results. Among untreated patients, 13 (51%) were female; 17 (68%) were Black; median age was 62 years old. The majority (84%) had injecting drug use (IDU) as HIV transmission risk factor; 14 (56%) were prescribed medication-assisted treatment. Median time since HIV and HCV diagnosis was 25 and 19 years, respectively. Clinic-level barriers were noted in 19 (76%) and included lack of evaluation, treatment not recommended or implemented. Concomitant structural barriers included unstable housing for 11 (44%) and lack of transportation for eight (32%). Most patients had history of illicit substance use (84%) and mental health issues (68%). Many (76%) had multiple potential barriers. Conclusions. Multiple overlapping barriers spanning clinic and patient level domains including social determinants of health were the norm in persons with long-standing HIV/HCV coinfection who have not received HCV treatment. Interventions will require innovative, multi-disciplinary and personalized approaches.

Clinical Practice Patterns of Interprofessional Collaboration: Considerations for Athletic Training Education

Context As required elements of accreditation, interprofessional education (IPE), and interprofessional collaborative practice (IPCP) are key considerations for athletic training educators, students, and practicing professionals. Objective Despite the emphasis on IPE and IPCP, little information exists regarding which health care professionals athletic trainers should collaborate with outside of physicians. In addition, no study has established which professionals athletic training students should be educated alongside in preparation for future interprofessional collaboration. Design Cross-sectional survey. Setting Clinical practice settings. Patients or Other Participants Stratified sample of 105 athletic trainers across various employment settings. Data Collection and Analysis Participants selected the top 5 health care professionals with whom they currently interact, desire to collaborate, and believe students should be learning to interact with during clinical practice. Participants indicated how much time they spent in collaborative practice and the frequency and method of their interactions. We analyzed data using descriptive statistics including means, standard deviations, and frequency counts. Results In addition to physicians, participants identified physical therapists, physician assistants, nurses, and nurse practitioners as the primary professionals with whom they interacted in the past 12 months. Participants identified a desire to collaborate with sport and exercise psychologists, physical therapists, nutritionists, physician assistants, and certified or licensed professional counselors. In addition, participants indicated that athletic training students should learn with physical therapists, paramedics or emergency medical technicians (EMTs), physician assistants, nutritionists, and sport and exercise psychologists in preparation for future clinical practice. Regarding time, the majority (64.7%) of participants interact with other health care professionals multiple times a day or week. Conclusions These results are indicative of the need to prepare athletic training students to engage in collaboration with professionals beyond the naturally occurring partnerships with physicians. Educators could use these findings in the development or modification of IPE experiences, and the results may be considered in the development of continuing education opportunities to enhance practicing athletic trainers’ collaborations.

A Qualitative Assessment of Clinical Practice Guidelines and Patterns for Congenital Cytomegalovirus in the United States.

Cytomegalovirus (CMV) infection during pregnancy may result in long-term health problems for children with congenital CMV (cCMV). Currently, no prevention or treatment interventions are approved by the Food and Drug Administration for a cCMV indication. Healthcare provider and public awareness is low, and formal clinical practice guidelines and local practice patterns vary. A pilot study of eight cCMV experts was performed using qualitative semi-structured interviews to better understand clinical practice guidelines and patterns in the United States. Results from participant interviews highlighted the need for better prenatal diagnostic techniques, broader neonatal screening opportunities, and more robust evidence supporting intervention strategies. Healthcare provider and public partnerships are essential for advancing cCMV guidelines and improving care delivery. Our results provide a preliminary knowledge base and framework for developing a consensus cCMV research agenda to address evidence gaps that limit the revision of clinical practice guidelines. The changes in clinical practice patterns that may arise as a result of further research have the potential to reduce risk during pregnancy and improve care for children with cCMV infection.

Utilization of Instrumentation in Swallowing Assessment of Surgical Patients during COVID-19.

The aim of this study is to describe a measured return to instrumental dysphagia assessments for our vulnerable surgical patient population, such that best practice patterns could be resumed and our staff kept safe from transmission of COVID-19. A retrospective medical record review provided data on clinical practice patterns of swallowing assessment in an at-risk surgical patient population. Outcomes of this study support protocols that allow clinicians to safely resume the use of instrumental assessment and return to best practice in dysphagia assessment for our surgical patient population.

Clinical practice patterns of speech-language pathologists for screening and identifying dysphagia.

To identify how speech-language pathologists (SLPs) in the United States are screening for and identifying dysphagia. To do this, we examined the approaches most often used to screen for dysphagia and the influence of contextual factors such as setting, continuing education and means of staying up to date with the most current literature on screening approaches. A web-based survey composed of 32 questions was developed and field tested for content, relevance and workflow. The survey was distributed online, via social media, online SLP forums and through the American Speech-Language-Hearing Association's Special Interest Group 13 (swallowing disorders). One hundred and thirty-seven clinicians from the United States completed the survey and were included for analysis using descriptive statistics and linear regression modelling to assess associations of continuing education and years practicing with screening protocols and consumption of evidence. Respondents worked in a variety of settings, including acute care, skilled nursing facilities, and inpatient rehabilitation. Most respondents worked with adult populations (88%). The most common screening protocols reported were a volume-dependent water swallow test (74%), subjective patient report (66%), and trials of solids/liquids (49%). Twenty-four percent (24%) reported using a questionnaire, the Eating Assessment Tool (80%) being most common. How clinicians consume their evidence was significantly associated with the types of screening approaches used. Continuing education hours were significantly associated with dysphagia screening protocol choice (p < 0.001) and how clinicians stayed up to date with evidence (p < 0.001). Results from this study provide an in-depth look at the choices clinicians are making in the field regarding how to effectively screen patients for the presence of dysphagia. Contextual factors such as evidence base consumption patterns should serve researchers to continue seeking alternative ways to share evidence with clinicians, accessibly. Associations between continuing education and protocol choice show the need for continued evidence-based and high-quality continuing education opportunities. This study provides an in-depth look at the choices clinicians are making in the field regarding effective dysphagia screening practices. Clinician screening choices are examined with contextual factors such as evidence base consumption patterns and continuing education. This paper increases knowledge of the most used dysphagia screening practices and context for clinicians and researchers to improve use, evidence and dissemination of best practices.

Association of ulcerative colitis symptom severity and proctocolectomy with multidimensional patient-reported outcomes: a cross-sectional study

BackgroundThe YOu and Ulcerative colitis: Registry and Social network (YOURS) is a large-scale, multicenter, patient-focused registry investigating the effects of lifestyle, psychological factors, and clinical practice patterns on patient-reported outcomes in patients with ulcerative colitis in Japan. In this initial cross-sectional baseline analysis, we comprehensively explored impacts of symptom severity or proctocolectomy on nine patient-reported outcomes.MethodsPatients receiving tertiary care at medical institutions were consecutively enrolled in the YOURS registry. The patients completed validated questionnaires on lifestyle, psychosocial factors, and disease-related symptoms. Severity of symptoms was classified with self-graded stool frequency and rectal bleeding scores (categories: remission, active disease [mild, moderate, severe]). The effects of symptom severity or proctocolectomy on nine scales for quality of life, fatigue, anxiety/depression, work productivity, and sleep were assessed by comparing standardized mean differences of the patient-reported outcome scores.ResultsOf the 1971 survey responses analyzed, 1346 (68.3%) patients were in remission, 583 (29.6%) had active disease, and 42 (2.1%) had undergone proctocolectomy. A linear relationship between increasing symptom severity and worsening quality of life, fatigue, anxiety, depression, and work productivity was observed. Patients with even mild symptoms had worse scores than patients in remission. Patients who had undergone proctocolectomy also had worse scores than patients in remission.ConclusionsUlcerative colitis was associated with reduced mood, quality of life, fatigue, and work productivity even in patients with mild symptoms, suggesting that management of active ulcerative colitis may improve patient-reported outcomes irrespective of disease severity.

Japanese clinical practice patterns of primary nephrotic syndrome 2021: a web-based questionnaire survey of certified nephrologists.

With the publication of the "Evidence-Based Clinical Practice Guideline for Nephrotic Syndrome 2020," we examined nephrologists' adherence to the recommendations of four of its clinical questions (CQs). This was a cross-sectional web-based survey conducted between November and December 2021. The target population comprised nephrologists certified by the Japanese Society of Nephrology who were recruited using convenience sampling. The participants answered six items regarding the four CQs about adult patients with nephrotic syndrome and their characteristics. In total, 434 respondents worked in at least 306 facilities, of whom 386 (88.9%) provided outpatient care for primary nephrotic syndrome. Of these patients, 179 (41.2%) answered that they would not measure anti- phospholipase A2 receptor antibody levels in cases of suspected primary membranous nephropathy (MN) in which kidney biopsy was not possible (CQ1). Regarding immunosuppressants as maintenance therapy after relapse of minimal change nephrotic syndrome (CQ2), cyclosporine was the most common choice (290 [72.5%] and 300 [75.0%] of 400 respondents after the first and second relapses, respectively). The most common treatment for steroid-resistant cases of primary focal segmental glomerulosclerosis (CQ3) was cyclosporine (323 of 387, 83.5%). For the initial treatment of primary MN with nephrotic-range proteinuria (CQ4), corticosteroid monotherapy was the most common choice (240 of 403, 59.6%), followed by corticosteroid and cyclosporine (114, 28.3%). Gaps in recommendations and practices regarding serodiagnosis and treatment of MN (i.e., CQ1 and 4) are observed, suggesting the need to address the barriers to their insurance reimbursement and the lack of evidence behind them.
