The prescription and monitoring of conventional synthetic disease-modifying anti-rheumatic drugs: British Society for Rheumatology guideline scope.

This guideline will provide up-to-date, evidence-based recommendations on the safe use of non-biologic DMARDs, also called conventional synthetic DMARDs (csDMARD), across the full spectrum of autoimmune rheumatic diseases. The guideline will update the guideline published in 2017 and will be expanded to include people of all ages. Updated information on the monitoring of DMARDs and vaccinations will be included. The guideline will be developed using the methods and processes described in the British Society for Rheumatology's 'Creating clinical guidelines: our protocol', updated 2023.

Improved Cardiac Rehabilitation Referral Rate Utilizing a Multidisciplinary Quality Improvement Team.

Introduction Cardiac rehabilitation (CR) is an underutilized resource in patients with ischemic heart disease, despite being a Class IA recommendation. In this study, a multidisciplinary quality improvement (QI) team aimed to improve CR referrals by standardizing the ordering process at our hospital system. Method By using a collaborative approach involving the electronic medical record (EMR), medical provider education, and hospital protocols, our two-hospital healthcare system was able to successfully identify barriers to CR referral rates and implement interventions for these barriers. All physicians and medical providers, including ancillary staff, were educated on the EMR order sets to improve compliance by using automated order sets in the EMR. The CR referral order in the EMR included a statement regarding the application of evidence-based medicine, and a computerized provider order entry was included as a reminder to the ordering provider. The use of EMR was monitored monthly by the QI committee. Chi-square test and odds ratios were obtained for statistical analysis. Results Through provider-EMR education and patient education on discharge, CR referral rates significantly improved from 51.2 to 87.1% (p = 0.0001) in a 12-month period. The study included 1,499 patients in total. The improvement was statistically significant regardless of patient gender, race, or insurance coverage. Additionally, subgroup analysis in this study found that prior to standardization of the ordering process, African American patients were significantly less likely to be referred to CR compared to Caucasian patients. (51.2% vs. 41.0%, p=0.01). There was no statistically significant difference in the likelihood of CR referral between Caucasian and African American patients following the intervention (84.0% vs. 78.0%, p = 0.166). Conclusion This study shows that CR is an underutilized resource and that effective QI initiatives may not only increase CR referral rates but also close the gap between racial inequities in referral rates. Future research with multi-center randomized control trials is needed to further enhance its external generalizability to other institutions.

Intestinal Intussusception Complicating an Undiagnosed Burkitt Lymphoma in a Pediatric Arab Patient.

Burkitt's lymphoma (BL) is considered an aggressive form of a non-Hodgkin B-cell lymphoma, representing less than 5% of all pediatric malignancies and 30% of pediatric lymphomas. However, intestinal BL may present as a lead point, causing intussusception. Surgery continues to be the gold standard for the treatment and identification of localized tumors to ensure complete removal with proper margin. In this report, we describe a hidden BL presenting as intestinal intussusception in an eight-year-old Arab boy. A computed tomography (CT) scan of the abdomen revealed an ileoileal intussusception with multiple enlarged lymph nodes. The report discusses the role of histopathology, supported by immunohistochemistry studies, in establishing the diagnosis. It also covers the significance of proper laparoscopic surgery and chemotherapy in the management of this child.

A single-centre observational study of delayed defaecation in brain-injured patients in an adult intensive care unit.

BACKGROUND: The incidence of delayed defaecation is high in enterally fed ventilated patients in intensive care units (ICUs). Those with brain injury may be harmed by increased intracranial pressure if delayed defaecation leads to abdominal distension. There are no studies evaluating a bowel guideline in the treatment of delayed defaecation in ventilated brain-injured ICU patients. OBJECTIVE: The objective of this study was to assess the incidence and clinical associations of delayed defaecation and level of compliance to an ICU bowel guideline. METHODS: Data were collected on ventilated adult patients with brain injury admitted for more than 3 days to one New Zealand ICU over a 2-year period. RESULTS: Data were analysed for 117 patients; 56 (48%) who defaecated within 3 days of ICU admission (Group one) and 61 (52%) with delayed defaecation after 3 days (Group two). Compliance with the bowel guideline was low. Only 1 of 61 patients who should have had a rectal examination did so, and only 7 of 61 patients who should have had an aperient on day 3 did so. All seven received Movicol®, which was not part of the guideline. Use of aperients and enemas was found to be associated with stool passage (odds ratio: 93; 95% confidence interval: 5.2-1668; p = 0.002). Patients with delayed defaecation had longer ICU stays (mean 7.1 ± 4 SD vs 5.9 ± 3 days, p = 0.07) and more often had high gastric residual volumes after day 4 (27/61 vs 14/56; p = 0.003). No differences were seen between the groups in the incidence of ventilator-associated pneumonia, bacterial infections, diarrhoea, vomiting, duration of mechanical ventilation, or mortality. CONCLUSION: Delayed defaecation was common, and compliance with the guideline was low. Movicol® and phosphate enemas were effective in stool production.

Definition, criteria, and core concepts of guidelines for the management of obesity disease in Japan.

To identify those who might benefit from weight reduction within a large population of obese individuals, Japan Society for the Study of Obesity (JASSO) advocated the concept of "obesity disease." Here we summarize the definition, criteria, and core concepts for the management of obesity disease based on JASSO's latest guideline. JASSO defines obesity as excessive fat storage in adipose tissue associated with a BMI of ≥25 kg/m2. The threshold BMI of obesity is low as compared to Western countries given that Japanese individuals tend to develop obesity-related health disorders at lower BMI. Obesity with a BMI of ≥35 kg/m2 is referred to as "high-degree obesity" as treatment strategies vary based on the degree of obesity. Obesity is diagnosed as "obesity disease" if accompanied by any of the 11 specific obesity-related health disorders that weight reduction can prevent or alleviate, or if it meets the criteria for visceral fat obesity with a visceral fat area of ≥100 cm2. The initial weight reduction goals for high-degree obesity disease range from 5% to 10% of their current body weight, depending on the associated health disorders. That for those with obesity disease who do not qualify as high-degree is 3% or more. If these initial goals are not achieved, intensifying dietary therapy or introducing drug therapy (or both) may be necessary. While surgical treatment is primarily indicated for high-degree obesity disease, it might be appropriate for cases of obesity disease with a BMI <35 kg/m2, depending on the accompanying health disorders. Enhancing the quality of life for individuals with obesity or obesity disease necessitates a broader societal approach, emphasizing the resolution of related stigma.

[Guidelines for the management of adverse effects of anti-seizure medications (2023)]. / 抗癫痫发作药物不良反应管理指南（2023）.

Epilepsy is a prevalent neurological disorder with a complex etiology and an unclear pathogenesis. In order to standardize the management of adverse effects caused by anti-seizure medications (ASMs), the Youth Committee of the Chinese Association Against Epilepsy (CAAE), in collaboration with the CAAE Precision Medicines and Adverse Effect Monitoring Committee, has developed a guideline: guidelines for the management of adverse effects of anti-seizure medications (2023). This guideline addresses 13 clinical questions related to the management of adverse effects of ASMs in the nervous system, cardiovascular system, and fetus. Its primary objective is to provide guidance to medical professionals specializing in pediatric neurology, neurology, and neurosurgery in China, and to facilitate their clinical practice.

Diagnosis and management of glycogen storage disease type IV, including adult polyglucosan body disease: A clinical practice resource.

Glycogen storage disease type IV (GSD IV) is an ultra-rare autosomal recessive disorder caused by pathogenic variants in GBE1 which results in reduced or deficient glycogen branching enzyme activity. Consequently, glycogen synthesis is impaired and leads to accumulation of poorly branched glycogen known as polyglucosan. GSD IV is characterized by a remarkable degree of phenotypic heterogeneity with presentations in utero, during infancy, early childhood, adolescence, or middle to late adulthood. The clinical continuum encompasses hepatic, cardiac, muscular, and neurologic manifestations that range in severity. The adult-onset form of GSD IV, referred to as adult polyglucosan body disease (APBD), is a neurodegenerative disease characterized by neurogenic bladder, spastic paraparesis, and peripheral neuropathy. There are currently no consensus guidelines for the diagnosis and management of these patients, resulting in high rates of misdiagnosis, delayed diagnosis, and lack of standardized clinical care. To address this, a group of experts from the United States developed a set of recommendations for the diagnosis and management of all clinical phenotypes of GSD IV, including APBD, to support clinicians and caregivers who provide long-term care for individuals with GSD IV. The educational resource includes practical steps to confirm a GSD IV diagnosis and best practices for medical management, including (a) imaging of the liver, heart, skeletal muscle, brain, and spine, (b) functional and neuromusculoskeletal assessments, (c) laboratory investigations, (d) liver and heart transplantation, and (e) long-term follow-up care. Remaining knowledge gaps are detailed to emphasize areas for improvement and future research.

A single-center multidisciplinary study analyzing thyroid nodule risk stratification by comparing the thyroid imaging reporting and data system (TI-RADS) and American thyroid association (ATA) risk of malignancy for thyroid nodules.

OBJECTIVES: The thyroid imaging reporting and data system (TI-RADS) and 2015 American Thyroid Association (ATA) guidelines are two well-known risk stratification systems for classifying thyroid nodules based on cancer risk. This study aims to evaluate the diagnostic efficacy of these two systems in predicting malignancy in patients undergoing thyroid surgery. METHODS: We studied data on 120 individuals who were scheduled to undergo surgery for benign or malignant nodular diseases of the thyroid gland between October 2017 and October 2019. The TI-RADS category and ultrasound pattern based on ATA guidelines were assigned to dominant thyroid nodule categories by two experienced radiologists blinded to patients' previous thyroid ultrasonography and fine-needle aspiration biopsy results. A pathologist with experience in thyroid diseases blinded to patients' sonographic and clinical data reviewed the thyroidectomy specimens. RESULTS: A total of 120 patients, 88 women and 32 men, were included in our study. Final histopathological results were as follows: 50% (n=60) papillary thyroid carcinoma, 36.6% (n=44) benign nodular thyroid diseases, 4.1% (n=5) follicular adenoma, 2.5% (n=3) hurtle cell adenoma, 1.7% (n=2) follicular thyroid carcinoma, 1.7% (n=2) medullary thyroid carcinoma, 1.7% (n=2) hurtle cell carcinoma, and 1.7% (n=2) follicular tumor of uncertain malignancy potential. The sensitivity, specificity, positive predictive value, and negative predictive value for TI-RADS were 80%, 56%, 72%, and 67%, respectively, and that for ATA were 80%, 64%, 76%, and 69%, respectively. CONCLUSION: The TI-RADS and ATA showed similar rates of sensitivity, specificity, NPV, and PPV. Our observed risk of malignancy was higher than expected for the ACR TI-RADS 3-5 categories and the very low, low, and intermediate suspicion risk strata in the ATA guidelines. We found no difference between observed and expected malignancy risk for the ACR TI-RADS 2's and ATA's high suspicion categories.

Lung ultrasound to guide the administration of exogenous pulmonary surfactant in respiratory distress syndrome of newborn infants: A retrospective investigation study.

Background: Respiratory distress syndrome (RDS) is a common disease that seriously endangers the life and safety of newborns, especially premature infants. Exogenous pulmonary surfactant (PS) is the specific agent for the treatment of neonatal RDS. Lung ultrasound (LUS) has been successfully used in the diagnosis of RDS, but its value in guiding the application of PS is still unclear. This paper explored whether the application of PS under LUS monitoring has some advantages, including (1) decreasing the misdiagnosis rate of RDS and decreasing probability of using PS, and (2) reducing the dose of PS without reducing the therapeutic effect. Methods: This study included two parts. Part 1: To decide whether the LUS is good to differentiate RDS from other lung diseases in the premature infants. All patients who were diagnosed with RDS and required PS treatment based on conventional criteria were routinely examined by LUS. Then, according to LUS findings, we decided whether they needed to receive PS treatment. Part 2: To see the dose reduction of surfactant is applicable. In RDS patients diagnosed based on LUS presentation and treated with Curosurf (Chiesi Pharmaceutical, Parma, Italy), the dose of Curosurf was compared with that recommended by the European RDS management guidelines. Results: (1) Since March 2017, 385 newborn infants admitted to our neonatal intensive care unit met the traditional diagnostic criteria of RDS. Of these, only 269 cases were diagnosed with RDS and needed PS treatment according to LUS manifestations. The other 116 infants who did not meet the criteria for ultrasound diagnosis of RDS did not receive PS supplementation but obtained good outcomes, that is LUS findings decreased a misdiagnosis rate of RDS by 30.1% and subsequently resulted in a 30.1% reduction in PS use. (2) Among the 269 RDS patients diagnosed based on LUS findings, 148 were treated with Curosurf (another 121 RDS infants who received domestic PS treatment were not included in the study group), and the average dose was 105.4 ± 24.3 mg/kg per time, which is significantly lower than the dose of 200 mg/kg per time recommended by the European RDS guidelines. (3) The mortality rate of RDS patients was 0%, and no patients had ventilator-associated pneumonia or bronchopulmonary dysplasia in this study. Conclusion: LUS can decrease the misdiagnosis rate of RDS, thereby decreasing the probability of using PS and decreasing the dose of PS, and can help RDS infants to achieve better outcomes.

Low-Risk Antenatal Care Enhanced by Telemedicine: A Practical Guideline Model / Atenção ao pré-natal de baixo risco potencializada por telemedicina: Diretriz clínica prática

Abstract Objective To develop a protocol for hybrid low-risk prenatal care adapted to Brazilian guidelines, merging reduced face-to-face consultations and remote monitoring. Methods The PubMed, Embase, and Cochrane Library databases were systematically searched on telemedicine and antenatal care perspectives and adaptation of the low-risk prenatal care protocols recommended by the Ministry of Health and by the Brazilian Federation of Gynecology and Obstetrics Associations. Results Five relevant articles and three manuals were included in the review, for presented criteria to develop this clinical guideline. We identified, in these studies, that the schedule of consultations is unevenly distributed among the gestational trimesters, and ranges from 7 to 14 appointments. In general, the authors propose one to two appointments in the first trimester, two to three appointments in the second trimester, and two to six appointments in the third trimester. Only three studies included puerperal evaluations. The routine exams recommended show minimal variations among authors. To date, there are no validated Brazilian protocols for prenatal care by telemedicine. The included studies showed that pregnant women were satisfied with this form of care, and the outcomes of interest, except for hypertensive diseases, were similar between the groups exposed to traditional and hybrid prenatal care. Conclusion The presented guideline comprises the Ministry of Health recommendations for low-risk prenatal care and reduces exposure to the hospital environment and care costs. A randomized clinical trial, to be developed by this group, will provide real-world data on safety, effectiveness, satisfaction, and costs.

Resultados Cinco artigos relevantes e três manuais foram incluídos na revisão por preencherem critérios para o desenvolvimento desta diretriz clínica. Nos estudos incluídos, identificou-se que o cronograma de consultas se distribui de forma desigual entre os trimestres gestacionais, variando entre 07 e 14 encontros. De forma geral, os autores propõem uma a duas consultas no primeiro trimestre, duas a três consultas no segundo trimestre e duas a seis consultas no terceiro trimestre. Somente três estudos incluíram avaliações puerperais. A rotina de exames preconizada apresenta mínimas variações entre os autores. Até o momento, não existem protocolos brasileiros validados para atendimento pré-natal por telemedicina. Os estudos incluídos evidenciaram a satisfação das gestantes em relação a esta forma de atendimento, e os desfechos de interesse, excetuando doenças hipertensivas, foi semelhante entre os grupos expostos ao pré-natal tradicional e ao pré-natal híbrido. Conclusão A diretriz apresentada contempla as recomendações do Ministério da Saúde para atendimento pré-natal de gestantes de baixo risco, reduz a exposição ao ambiente hospitalar e os custos de atendimento. Seu emprego em um ensaio clínico randomizado, a ser desenvolvido por este grupo, proporcionará dados de mundo real, relativos à segurança, efetividade, satisfação e custos.

[The guidelines of the Federal Joint Committee on acute pain management : Background and consequences for the practice in hospitals]. / Die Vorgaben des Gemeinsamen Bundesausschusses zum Akutschmerzmanagement : Hintergründe und Konsequenzen für die Praxis im Krankenhaus.

The quality of postoperative pain therapy in Germany shows a heterogeneous treatment practice and large differences in quality between individual institutions, The patient representatives in the Federal Joint Committee (G-BA) have therefore decisively campaigned for many years that instruments of non-legislative standards are employed in order to noticeably improve the quality of perioperative pain therapy for patients in Germany. As a result of these efforts, in October 2020 a binding specification for internal quality management was included in the quality management guidelines (QM-RL) by the G­BA. This describes in concrete terms the structural and procedural requirements for an internal quality management of acute pain for all institutions in which operations and comparable potentially painful interventions are carried out. This article describes the content of this regulation and the resulting consequences for the institutions, the medical and administrative management and especially the role of anesthesia.

Concordance of Patient Expectations Regarding Guideline Recommendations for Management of Psychosocial Factors in Low Back Pain: A Cross-sectional Study.

BACKGROUND: Guidelines for low back pain (LBP) management recommend addressing psychosocial risk factors such as stress and depression, which have been shown to play a prognostic role in nonspecific LBP. LBP management has been found to diverge from published recommendations. The reasons why remain unclear and may be related to patient views and expectations regarding the causes and treatment of LBP. OBJECTIVES: We examined the degree to which patient views regarding psychosocial factors coincided with core recommendations and statements of the German national guideline for nonspecific LBP, as well as factors affecting those views. STUDY DESIGN: Cross-sectional study. SETTING: Data were gathered from June 2018 through September 2018 in 13 general practices in Mecklenburg-Wets Pomerania, Germany. METHODS: Practice staff approached all patients entering the practice, regardless of the reason for consultation, during 3 consecutive days and offered study participation. After providing informed consent, patients received a questionnaire to complete prior to consultation. Nonresponse bias was addressed by using inverse probability weights. Descriptive analysis and multivariate logistic regression models were performed. RESULTS: A total of 977 patient questionnaires were included in the analysis. One-third to one-half of the patients disagreed and one-third agreed that psychological problems and their treatment play a role in LBP management. A significant proportion (13-25%) was undecided. However, relaxation techniques were well accepted. Patients with higher education levels, poorer health status, and more severe LBP but no pain medication in the last 12 months were more likely to expect psychosocial diagnostics and treatment and regarded relaxation techniques as potentially helpful. More severe pain and lower levels of education were associated with disagreement with guideline recommendations and statements regarding management of psychosocial factors. LIMITATIONS: Recall bias is possible, as patients were asked to recall their LBP history. However, we limited the recall time to the last 12 months. Data on income, employment status and co-morbidities were not collected and may have affected the responses. However, educational status, health status, and age were collected. CONCLUSION: A significant portion of patients did not agree that psychosocial aspects should be addressed in LBP. Pain severity, health status, level of education, and previous treatment experience appear to affect patient views. These results highlight the importance of careful patient counseling regarding psychosocial factors and screening for psychosocial problems in LBP, when indicated. Additionally, educational initiatives may help bring patient expectations into agreement with recommendations.

Three ultrasound phenotypes of non-invasive follicular thyroid neoplasm with papillary-like nuclear features proposed for imaging-pathology analysis: single center experience.

BACKGROUND: The terminology "non-invasive follicular thyroid neoplasm with papillary-like nuclear features" (NIFTP) was introduced to reduce overtreatment of thyroid carcinomas with indolent behavior. However, limited literature discussed the sonographic features of the entity in depth. The objective of this study is to summarize sonographic subtypes of NIFTP for precise diagnosis. METHODS: From January 2017 to June 2020, 13,531 consecutive patients underwent surgery for thyroid nodules were reviewed; 30 patients (0.22%) with 30 NIFTP were eligible for this retrospective observational study. We evaluated ultrasound features of all the lesions and distributed them into 3 major types of ultrasound appearance using pattern recognition. Systemic literature review concerning ultrasonography of NIFTP was also performed. RESULTS: At sonography, all the NIFTP lesions were classified into three types: 19 (63.3%) were categorized into type A-oval and solid nodule without other high-suspicion features, 7 (23.3%) into type B-partially cystic mass without high-suspicion features, 4 (13.3%) into type C-hypoechoic solid nodule with high-suspicion features including irregular margins, microcalcifications, taller-than-wide shape. CONCLUSIONS: Three ultrasound patterns were proposed by us for ultrasound-cytopathology correlation analysis.

Definition and management of colorectal polyposis not associated with APC/MUTYH germline pathogenic variants: AIFEG consensus statement.

An expert consensus panel convened by the Italian Association for Inherited and Familial Gastrointestinal Tumors (Associazione Italiana per lo Studio della Familiarità ed Ereditarietà dei Tumori Gastrointestinali, AIFEG) reviewed the literature and agreed on a number of position statements regarding the definition and management of polyposis coli without an identified pathogenic mutation on the APC or MUTYH genes, defined in the document as NAMP (non-APC/MUTYH polyposis).

Management guideline for Werner syndrome 2020 1. Dyslipidemia and fatty liver associated with Werner syndrome.

For the purpose of examining the characteristics of dyslipidemia and fatty liver in patients with Werner syndrome in Japan in recent years, we searched all case reports of Japanese Werner syndrome reported on Medical Online and PubMed since 1996, and collected and examined the data and clinical features described in these reports. In addition, as there are few descriptions of treatment methods in these reports from Medical Online and PubMed, we analyzed 12 cases for which detailed data on treatment methods are available at Chiba University. Geriatr Gerontol Int 2021; 21: 133-138.

Management guideline for Werner syndrome 2020. 2. Sarcopenia associated with Werner syndrome.

AIM: Sarcopenia is defined as a condition that combines decreased skeletal muscle mass with weakness or decreased physical function. It is well known that in older adults, the presence of sarcopenia is a risk of frailty, falls and physical dysfunction. Patients with Werner syndrome are characterized by visceral fat accumulation and thin limbs, but the prevalence of sarcopenia in patients with Werner syndrome has not been investigated. METHODS: A literature search was conducted using Werner syndrome and skeletal muscle as keywords. We also analyzed data from our 7 Werner syndrome patients. RESULTS: A literature search on the relationship between Werner syndrome and skeletal muscle yielded only one article reported from Japan. According to this paper, a decrease in skeletal muscle mass (appendicular skeletal muscle index) was observed in all 9 Werner syndromes investigated. On the other hand, in our 7 Werner syndrome patients, their appendicular skeletal muscle indexes were below the standard value except for one male patient who had continued resistance exercise. CONCLUSION: The decrease in skeletal muscle mass frequently occurs in patients with Werner syndrome. However, resistance exercise may prevent the appearance of sarcopenia and requires early intervention in patients with Werner syndrome. Geriatr Gerontol Int 2021; 21: 139-141.

Management guideline for Werner syndrome 2020. 7. Skin ulcer associated with Werner syndrome: Dermatological treatment.

Skin ulcers in Werner's syndrome often arise from hyperkeratotic lesions and trauma to pressure points such as the plantar region, and are more difficult to treat than wound healing in healthy individuals. Multiple factors contribute to the intractable skin ulcers in Werner's syndrome, including skin thinning, sclerosis, fatty tissue loss, impaired blood flow, calcification, and excessive pressure due to osteoarticular deformity. Treatment includes topical application of a keratolytic agent for keratosis around the ulcer. Treatment of ulcers is the same as for normal ulcers, and if the ulcer is associated with infection and necrotic tissue, surgical debridement with a scalpel or scissors should be performed as much as possible after washing with saline or mildly warm water or with an antibacterial agent. Topical medications that promote softening and debridement of the necrotic tissue are used with careful control of moisture in the wound. Topical agents that promote granulation should be used in wounds where necrotic tissue has been removed without infection. Dressings to maintain a moist environment in the wound may also be useful. If the wound does not improve with conservative treatment, surgical treatment should be considered. Geriatr Gerontol Int 2021; 21: 160-162.

The KWAK TI-RADS and 2015 ATA guidelines for medullary thyroid carcinoma: Combined with cell block-assisted ultrasound-guided thyroid fine-needle aspiration.

OBJECTIVE: To compare the value of the thyroid imaging reporting and data system proposed by Kwak (KWAK TI-RADS) and the 2015 American Thyroid Association (ATA) guidelines for diagnosis of medullary thyroid carcinoma (MTC) and papillary thyroid carcinoma (PTC). To confirm the role of cell block (CB)-assisted fine-needle aspiration (FNA) in final diagnosis of MTC. DESIGN: Retrospective hospital-based cohort study. PATIENTS: Ninety-three patients with 29 MTCs, 31 PTCs and 33 thyroid adenomas (TAs) who underwent thyroidectomy from January 2010 to May 2019 were retrospectively reviewed. The KWAK TI-RADS and ATA guidelines were used to assess each thyroid nodule. FNA, CB-assisted FNA and core needle biopsy (CNB) were performed in final diagnosis. RESULTS: Age and ultrasound features (composition, echogenicity and shape) were significantly different between MTC and PTC. Sex and ultrasound features (echogenicity, margin and calcification) were significantly different between MTC and TA. The KWAK TI-RADS and ATA guidelines showed no significant difference for MTC (area under the curve [AUC]: 0.812 and 0.808; P = .37-.85) or PTC (AUC: 0.883 and 0.885; P = .25-.96). The KWAK TI-RADS and ATA guidelines showed high specificity and sensitivity for MTC (93.9% and 62.1%, 87.9% and 65.5%) and PTC (93.9% and 67.7%, 87.9% and 77.4%), respectively. For suspicious MTC (7 cases), CB-assisted FNA provide accuracy preoperative diagnosis. CONCLUSIONS: Although the diagnostic performance of the TI-RADS and ATA guidelines is worse for MTC than PTC, the difference is not statistically significant. CB-assisted FNA should be performed in thyroid nodules with 4a or lower suspicion to avoid misdiagnosis of MTC.

Comparison among TIRADS (ACR TI-RADS and KWAK- TI-RADS) and 2015 ATA Guidelines in the diagnostic efficiency of thyroid nodules.

PURPOSE: To compare the value of Thyroid Imaging Reporting and Data Systems proposed by Kwak (KWAK-TIRADS) and ACR (ACR TI-RADS) and 2015 American Thyroid Association (ATA) guidelines in the diagnosis of surgically resected thyroid nodules. METHODS: From January 2015 to December 2015, 2544 thyroid nodules in 1758 patients who underwent thyroidectomy at our center were included. The KWAK-TIRADS category, ACR TI-RADS and ultrasound (US) pattern based on ATA guidelines were assigned to each thyroid nodule. Nodules were divided into groups according to their maximal diameter further. RESULTS: Of all the nodules, 863 (33.9%) were benign, whereas 1681 (66.1%) were malignant. The malignancy percentage of ACR TI-RADS category 1, 2, 3, 4, and 5 were 0%, 1.3%, 9.1%, 52.5%, and 88.8%, respectively. KWAK-TIRADS and ATA guidelines showed a better diagnostic efficiency than ACR TI-RADS (P < 0.01). ACR TI-RADS demonstrated a higher specificity (79.7%, P < 0.05), whereas the ATA US pattern had a higher sensitivity (95.5%, P < 0.01). The TIRADS (KWAK-TIRADS and ACR TI-RADS) category and ATA guidelines performed better in differentiating nodules >1 cm. KWAK-TIRADS showed better diagnostic efficiency than the other methods in differentiating nodules >1 cm (AUC: 0.92, P < 0.01). CONCLUSIONS: KWAK-TIRADS and ATA guidelines provide a better diagnostic efficiency than ACR TI-RADS. The TIRADS (KWAK-TIRADS and ACR TI-RADS) category and ATA guidelines perform better in differentiating nodules >1 cm than nodules ≤1 cm. KWAK-TIRADS perform better in differentiating nodules >1 cm than other methods.
