The aim of this study was to investigate the prevalence of diastasis recti abdominis (DRA) and to find the possible risk factors for DRA based on two diagnostic criteria among women in long-term postpartum period. A cross-sectional study was conducted on 1000 postpartum women at five different time points (3, 5, 10, 20, and 30 years after partum, respectively). Inter-recti distance (IRD) was assessed using ultrasound imaging, while basic data were collected through self-reported questionnaires. Two diagnostic criteria, IRD > 2 cm and IRD > 3 cm, were used to present the prevalence of DRA. Univariate and multivariate analyses were employed to explore the risk factors for DRA. When using the diagnostic criterion of IRD > 2 cm for DRA, the prevalence was 36%, 31%, 22%, 26%, and 30% at 3, 5, 10, 20, and 30 years postpartum, respectively. When using the diagnostic criterion of IRD > 3 cm for DRA, the prevalence was 13%, 8%, 6%, 8%, and 10%, respectively. The results revealed that higher body mass index (BMI) was a risk factor for DRA at 10 years postpartum (p = 0.000), bigger number of parturitions was a risk factor at 3, 5, and 10 years postpartum (p = 0.000, 0.004 and 0.000), twins was a risk factor at 3 years postpartum (p = 0.001), and diabetes was a risk factor at 20 and 30 years postpartum (P = 0.000 and 0.004). (1) The prevalence of DRA in the long-term postpartum period was high, especially when IRD > 2 cm was used as the diagnostic criterion. (2) Higher BMI, bigger number of parturitions, twins and diabetes were independently associated with higher odds of DRA at different long-term postpartum time points. (3) The diagnostic criterion for DRA should be further improved to avoid excessive clinical diagnosis and treatment. (1) This study elucidated the prevalence and risk factors associated with long-term postpartum DRA, thereby enhancing clinical awareness and advocating for early intervention and prevention measures to mitigate serious adverse outcomes. (2) This study presented the research results using two diagnostic criteria, increasing comparability with existing studies. In addition, discussions on reasonable diagnostic criterion for DRA were also conducted to avoid excessive clinical diagnosis and treatment. [ABSTRACT FROM AUTHOR]

Background: Over the last five decades, a fair number of echocardiographic studies have evaluated the prevalence of mitral valve prolapse (MVP) in various cohorts of individuals, including heterogeneous study populations. The present systematic review has been primarily designed to summarize the main findings of these studies and to estimate the overall MVP prevalence in the general community. Methods: All echocardiographic studies assessing the MVP prevalence in various cohorts of individuals, selected from PubMed and EMBASE databases, were included. There was no limitation of time period. The risk of bias was assessed by using the National Institutes of Health (NIH) Quality Assessment Tool for Observational Cohort and Cross-Sectional Studies. Results: The full texts of 21 studies with 1354 MVP individuals out of 63,723 participants were analyzed. The overall pooled prevalence of MVP was 4.9% (range of 0.6–21%). When dividing the studies in two groups according to the echocardiographic criteria used for MVP diagnosis (less specific old criteria or more specific new criteria, respectively), the estimated pooled prevalence of MVP was 7.8% (range of 2–21%) for the older studies (performed between 1976 and 1998) and 2.2% (range of 0.6–4.2%) for the more recent ones (conducted between 1999 and 2021). Potential selection bias, hospital- or referral-based series, and the use of less specific echocardiographic criteria for MVP diagnosis have been indicated as the main reasons for the higher MVP prevalence detected by the older studies. MVP was commonly associated with a narrow antero-posterior thoracic diameter, isolated ventricular premature beats and nonspecific ST-T-wave abnormalities on a resting electrocardiogram, mild-to-moderate mitral regurgitation (MR), the reduced probability of obstructive coronary artery disease, and a low frequency of serious complications, such as severe MR, infective endocarditis, heart failure, stroke, and atrial fibrillation. Conclusions: MVP has a low prevalence in the general population, regardless of age, gender, and ethnicity, and is associated with a good outcome. [ABSTRACT FROM AUTHOR]

The European Society of Cardiology (ESC), the American College of Cardiology, the American Heart Association, and expert consensus documents provide different diagnostic criteria for myocarditis. Their overlap and prognostic value have never been compared. This study aims to assess and compare the predictive value of ESC criteria for clinically suspected myocarditis, updated Lake-Louise criteria (LLC), American Heart Association criteria for probable acute myocarditis (pAM), and expert consensus criteria for acute myocarditis (AM) and complicated myocarditis (CM). Patients with a clinical suspicion of myocarditis referred for cardiac magnetic resonance were enrolled at 2 centers. Those with any prior cardiomyopathy were excluded. The association of composite outcome events (heart failure hospitalization, recurrent myocarditis, sustained ventricular tachycardia, or death) with ESC diagnostic criteria, LLC, pAM, AM, and CM were compared. Among 1,557 consecutive patients referred for cardiac magnetic resonance with possible myocarditis, 1,050 (62.6% male; 48.9 ± 16.8 years of age) were without an alternative diagnosis. Of those, 938 (89.3%) met ESC criteria for clinically suspected myocarditis, 299 (28.5%) LLC, and 356 (33.9%), 216 (20.6%), and 77 (7.3%) pAM, AM, and CM, respectively. Adverse events occurred in 161 patients (15.3%) during a median follow-up of 3.4 years. The highest annualized event rates (6.6%) were observed in patients meeting LLC, whereas negative ESC criteria indicated excellent prognosis (0.7% annualized event rate). Among all myocarditis definitions, ESC criteria and LLC were the strongest multivariable outcome predictors and had independent and incremental prognostic value (HR adjusted : 3.87; 95% CI: 1.22-12.2; P = 0.021, and HR adjusted : 2.53; 95% CI: 1.83-3.49; P < 0.001, respectively) when adjusted for clinical characteristics. In a real-world cohort of patients with possible myocarditis, diagnosis was reached in most patients using ESC criteria whereas only approximately one-quarter of patients reached a diagnosis with LLC. The independent prognostic value of ESC-criteria and LLC highlights the complementary role of clinical and CMR-based findings in the diagnosis and risk stratification of myocarditis.

Summary: A decade after International Myeloma Working Group (IMWG) biomarkers (SLiM criteria) were introduced, this real‐world study examined their impact on diagnosis, therapy and outcomes in myeloma. Using the ANZ MRDR, 3489 newly diagnosed patients from 2013 to 2023, comprising 3232 diagnosed by CRAB ('CRAB patients', including 1758 who also satisfied ≥1 SLiM criteria) and 257 by SLiM ('SLiM patients') criteria were analysed. CRAB patients had higher R‐ISS and lower performance status, with no difference in cytogenetic risk. SLiM patients had improved progression‐free survival (PFS, 37.5 vs. 32.2 months, hazard ratio [HR] 1.31 [1.08–1.59], p = 0.003), overall survival (80.9 vs. 73.2 months, HR 1.64 [1.26–2.13], p < 0.001) and PFS2 (54.6 vs. 40.3 months, HR 1.51 [1.22–1.86], p < 0.001) compared with CRAB patients, partially explained by earlier diagnosis, with no differential impact between the plasma cell and light‐chain criteria on PFS. However, 34% of CRAB patients did not manifest SLiM characteristics, raising the possibility that SLiM features are associated with different biological behaviours contributing to a better prognosis, for example, improved PFS2 in SLiM patients suggested less disease resistance at first relapse. These data support earlier initiation of therapy by SLiM. The superior survival outcomes of SLiM versus CRAB patients highlight the importance of defining these subgroups when interpreting therapeutic outcomes at induction and first relapse.

Objective: The exact relationship among atypical periprosthetic femoral fractures (APFFs), typical periprosthetic femoral fractures (PFFs), and atypical femur fractures (AFFs) remains unclear. This study aimed to investigate the prevalence of APFFs among PFFs and to identify the clinical characteristics, management, and prognosis that distinguish APFFs from typical PFFs and AFFs to further determine the relationship among these three fracture types. Methods: In this retrospective study, we reviewed the clinical data of 117 consecutive patients who had PFFs after hip arthroplasty between January 2012 and December 2022 and further classified them into an APFF group and a typical PFF group according to the revised ASBMR diagnostic criteria for AFF. Moreover, patients who had subtrochanteric or femoral shaft fractures in the same period and met the diagnostic criteria for AFF were recruited and classified into the AFF group. Demographic information, minor features of AFF, comorbidities, history of medication usage, management, and complications were collected and compared among patients with typical PFFs, APFFs, and AFFs. Results: Eleven PFFs were identified as APFFs, and the prevalence of APFFs among PFFs was 9.4%. Significant differences were found in generalized increase in cortical thickness (p = 0.019), prodromal symptoms (p < 0.001), and the incidence of bilateral fractures (p = 0.010) among the groups, where the incidences of these minor features in the APFF group and the AFF group were higher than those in the typical PFF group. Of note, the duration of fracture healing of APFFs was significantly longer than that of typical PFFs and AFFs (p < 0.001 and p = 0.004, respectively). In addition, the APFF group and the AFF group had higher proportions of patients with rheumatoid arthritis (p = 0.004 and p = 0.027, respectively), bisphosphonate (BP) usage (p = 0.026 and p < 0.001, respectively), and longer duration of BP usage (p = 0.003 and p = 0.007, respectively) than the typical PFF group. Furthermore, significant differences were found in management (p < 0.001) and complication rate (p = 0.020) among the groups, and the rate of complications in the APFF group and the AFF group was higher than that in the typical PFF group. Conclusions: APFFs not only fulfilled the mandatory and major diagnostic criteria for AFF but also had many clinical characteristics, management and prognosis distinguishing them from typical PFFs but resembling AFFs; hence, the diagnostic criteria for AFF might be revised to incorporate APFF as a distinct subtype of the condition.

The akinetic crisis is a well-known, rare, potentially life-threatening condition in Parkinson's disease with subacute worsening of akinesia, rigidity, fever, impaired consciousness, accompanying vegetative symptoms and transient dopa-resistance. The akinetic crisis was historically supposed to be a "withdrawal syndrome" in the sense of discontinuation of dopaminergic medication. Recently, other "withdrawal syndromes" as the specific "dopamine agonist withdrawal syndrome" or "deep brain stimulation withdrawal syndrome" have been described as emergency situations with specific subacute symptom constellations. All three conditions require immediate start of the adequate therapy to improve the prognosis. Here, the diagnostic criteria and treatment options of these three acute, severely disabling syndromes will be reported along the current guidelines of the German Parkinson Guideline Group.

Sarcopenic obesity is the co‐existence of obesity and sarcopenia in individuals aged 40–75 years. The Japanese Working Group on Sarcopenic Obesity has developed diagnostic criteria tailored for the Japanese population, considering their unique characteristics compared with European populations. Our algorithm consists of two steps: screening and diagnosis. The screening of obesity mandates using waist circumference and/or body mass index (BMI) based on national standards, while screening for sarcopenia involves the "finger ring test" in addition to the Asian Working Group for Sarcopenia 2019 criteria. The final diagnosis of sarcopenia involves handgrip strength for low muscle strength, the five‐times chair stand test for low physical function, and limb skeletal muscle mass (corrected for BMI) for low muscle mass. Obesity is assessed by visceral fat area or body fat percentage. Sarcopenic obesity is then categorized into Stage I, with muscle weakness/loss of function, loss of muscle mass, and obesity; or Stage II, which includes complications. Further clinical validation is needed to refine the consensus and age range. Geriatr Gerontol Int 2024; 24: 997–1000. [ABSTRACT FROM AUTHOR]

ABSTRACT Background Objective Methods Results Conclusions Tooth wear is a multifactorial process resulting in the loss of dental hard tissues. For its assessment, the tooth wear evaluation system (TWES) 2.0 has been published. Previous studies on the TWES involved well‐trained practitioners, rather than nonexperts.The first aim of this study was to investigate the reliability of the assessment of tooth wear severity on dental hard tissues, using the TWES 2.0, by nonexperts. The second aim was to investigate the reliability of assessment of wear severity on dental restorations, using a third scale.Forty‐seven dental students evaluated at least 9 of 14 possible patient cases on dental casts and intraoral photographs. Cohen's kappa (agreement with sample solution) and Fleiss' kappa (Inter‐rater reliability) were calculated.The agreements of the operators' ratings compared to the sample‐solution resulted in Cohen's kappa between 0.02 and 0.9. The agreements were 0.34 for occlusal; 0.43 for vestibular; 0.57 for oral surfaces.Inter‐rater reliability (Fleiss' kappa) was 0.35 for occlusal, 0.17 for vestibular and 0.24 for oral assessment. The inter‐rater reliability of the ratings on tooth surfaces with restorations was lower with 0.21 (occlusal), 0.14 (vestibular) and 0.39 (oral). The agreement on different restorations differed tremendously.The ability to correctly assess the cases varied considerably between individual examiners. Within the limits of this study, assessment of restorations was slightly more challenging compared to natural teeth, particularly in occlusal regions or when the restorative material is gold. Subsequent studies should address whether enhanced training and improved definition of tooth wear grades result in higher reliability scores. [ABSTRACT FROM AUTHOR]

The definition of autism continually changes over time in line with the growth of autism studies and the influences of the neurodiversity movement. The current paper aims to present the ongoing changes in the definition and diagnostic criteria of Autism as well as to introduce the autistic and neurodiversity movement happening globally. It traces back histories of Autism from myths and legends, cases in history possibly related to autism, Kanner’s and Asperger’s pioneered works on autism, and the ongoing transformation of Autism diagnostic criteria presented by all versions of DSM. The contribution of adults with Autism organisations to the DSM-5 diagnostic criteria is highlighted and future studies aimed to confirm the effectiveness of the newly revised criteria of DSM-5-TR are suggested. Subsequently, the current paper also discusses the brief history and principles of the autistic and neurodiversity movements that are growing globally and reviews the evolving definition of autism. The possible impact caused by the changes in the definition on the well-being of individuals with Autism is presented as well as future predictions of Autism’s definition are discussed.

Background: Although an increasing number of patients with Birt-Hogg-Dubé syndrome (BHD) are being recognized in China, clinical and genetic characteristics are not well-defined. In addition, revised diagnostic criteria for the Chinese population was proposed in 2023, we aimed to explore their utility in clinical practice at a rare lung disease center. Methods: We retrospectively analyzed the data of 100 consecutive patients with BHD diagnosed according to the revised Chinese BHD criteria, encountered at the First Affiliated Hospital of University of Science and Technology of China from Jan 2017 to June 2023. Results: There were 100 patients (including 63 females) from 65 unrelated families in Eastern China, mostly Anhui Province. The common manifestations were pulmonary cysts (99%), pneumothorax (60%), and skin lesions (77%). Renal cancer and renal angiomyolipoma were detected in 5 patients each. 37% of patients had no family history of BHD. In total, 25 FLCN germline mutations were detected, including 6 novel mutations. In addition to hotspot mutation c.1285delC/dupC (17%), the most common mutations were c.1015 C > T (16%), c.1579_1580insA (14%), and exons 1–3 deletion (11%) in FLCN. Higher risk of pneumothorax was associated with exons 1–3 deletion mutation and c.1177-5_1177-3de1CTC compared to the hotspot mutation c.1285dupC (91% [95% CI: 0.31, 46.82, p = 0.015] and 67% [95% CI: 0.35, 71.9, p = 0.302] vs. 30%, respectively). The average delay in diagnosis was 7.6 years after initial symptoms. Chinese diagnostic criteria were mostly consistent with typical pulmonary presentations with supportive genetic evidence. Conclusion: In the Eastern Chinese region, patients with BHD present most commonly with pulmonary cysts associated with pneumothorax and skin lesions. However, low incidence of renal cancer along with unexpected renal angiomyolipoma was observed. Genotypic spectrum differed from that reported from other global regions, and genotype association of pneumothorax warrants further research. The revised Chinese criteria for BHD seem more appropriate in diagnosing BHD in Chinese patients. [ABSTRACT FROM AUTHOR]

We present an analysis of a case initially manifesting as bilateral horizontal gaze palsy, eventually diagnosed as multiple sclerosis (MS) with preclinical systemic lupus erythematosus (p-SLE). The patient, a 25-year-old male, exhibited restricted movement in both eyes. Cranial MRI revealed multiple demyelinating lesions; serum analyses indicated elevated levels of antinuclear antibodies (ANA), anti-Sm antibodies, and anti-nRNP antibodies. Oligoclonal bands were identified in the cerebrospinal fluid. Neurophysiological assessments demonstrated damage to the optic, auditory, and facial nerves. Given the clinical presentation, laboratory findings, and the progression of the disease, the final diagnosis was confirmed as MS associated with p-SLE. The onset of MS with oculomotor disturbances is rare and may be easily confused with neuropsychiatric systemic lupus erythematosus (NPSLE). Furthermore, the differentiation of p-SLE from undifferentiated connective tissue disease (UCTD) in the early stages presents significant challenges. Early identification of risk factors and close monitoring of disease activity is crucial for an accurate diagnosis. [ABSTRACT FROM AUTHOR]

Background Information on infective endocarditis (IE) caused by Cutibacterium spp. is limited and new Duke–International Society for Cardiovascular Infectious Diseases (ISCVID) criteria have not yet been properly assessed. We examined clinical characteristics, outcomes, and performance of diagnostic tests for Cutibacterium valvular and cardiac implantable electronic device–related IE (CIED-IE). Methods Data corresponding to all episodes of Cutibacterium IE recorded from 2008 to 2023 in a prospective national cohort including 46 Spanish hospitals were examined. Possible IE cases were reassessed using the new criteria. The sensitivity of blood cultures, valvular and CIED cultures, and polymerase chain reaction of the 16S rRNA gene and sequencing (16SPCR) was evaluated. Results Of 6692 episodes of IE, 67 (1%) were caused by Cutibacterium spp. with 85% affecting men. Of these, 50 were valve-related (45 prosthetic, 5 native) and 17 CIED-related. The new criteria identified 8 additional cases and reclassified 15 as definite IE. Intracardiac complications (abscess, pseudoaneurysm, perforation, or intracardiac fistula) occurred in 23 of 50 (46%) valvular IE episodes, leading to 18% mortality, and up to 40% mortality if surgery was indicated but could not be performed. All CIED-IE cases underwent device removal and no deaths were recorded. Positive diagnosis rates for blood cultures, valve/device cultures, and 16SPCR were 52%, 70%, and 82%, respectively. Conclusions Cutibacterium IE is a rare yet potentially life-threatening condition that warrants a high index of suspicion in men with endovascular prosthetic material. The new Duke-ISCVID criteria and molecular techniques are useful for its diagnosis. Considering a significant complication rate, cardiac surgery and removal of CIEDs play a key role in reducing mortality. [ABSTRACT FROM AUTHOR]

Background and Purpose Methods Results Conclusions The diagnostic criteria for myelin oligodendrocyte glycoprotein antibody (MOG‐IgG)‐associated disease (MOGAD) were published in 2023. We aimed to determine the performance of the new criteria in Latin American (LATAM) patients compared with the 2018 criteria and explore the significance of MOG–IgG titers in diagnosis.We retrospectively reviewed the medical records of LATAM (Argentina, Chile, Brazil, Peru, Ecuador, and Colombia) adult patients with one clinical MOGAD event and MOG‐IgG positivity confirmed by cell‐based assay. Both 2018 and 2023 MOGAD criteria were applied, calculating diagnostic performance indicators.Among 171 patients (predominantly females, mean age at first attack = 34.1 years, mean disease duration = 4.5 years), 98.2% patients met the 2018 criteria, and of those who did not fulfill diagnostic criteria (n = 3), all tested positive for MOG‐IgG (one low‐positive and two without reported titer). Additionally, 144 (84.2%) patients met the 2023 criteria, of whom 57 (39.5%) had MOG‐IgG+ titer information (19 clearly positive and 38 low‐positive), whereas 87 (60.5%) patients had no MOG‐IgG titer. All 144 patients met diagnostic supporting criteria. The remaining 27 patients did not meet the 2023 MOGAD criteria due to low MOG‐IgG (n = 12) or lack of titer antibody access (n = 15), associated with the absence of supporting criteria. The 2023 MOGAD criteria showed a sensitivity of 86% (95% confidence interval = 0.80–0.91) and specificity of 100% compared to the 2018 criteria.These findings support the diagnostic utility of the 2023 MOGAD criteria in an LATAM cohort in real‐world practice, despite limited access to MOG‐IgG titration.

Background and Purpose Methods Results Conclusions This study was undertaken to compare the sensitivity and specificity of the 2010 European Federation of Neurological Societies/Peripheral Nerve Society (EFNS/PNS) diagnostic criteria for multifocal motor neuropathy (MMN) with those of the American Association of Electrodiagnostic Medicine (AAEM).Sensitivity and specificity of the two sets of criteria were retrospectively evaluated in 53 patients with MMN and 280 controls with axonal peripheral neuropathy, inflammatory demyelinating polyneuropathy, or amyotrophic lateral sclerosis. Comparison of the utility of nerve conduction studies with different numbers of nerves examined was also assessed.The 2010 EFNS/PNS criteria had a sensitivity of 47% for definite MMN and 57% for probable/definite MMN, whereas the AAEM criteria had a sensitivity of 28% for definite MMN and 53% for probable/definite MMN. The sensitivity of the AAEM criteria was higher when utilizing area compared to amplitude reduction to define conduction block. Using supportive criteria, the sensitivity of the 2010 EFNS/PNS criteria for probable/definite MMN increased to 64%, and an additional 36% patients fulfilled the criteria (possible MMN). Specificity values for definite and probable/definite MMN were slightly higher with the AAEM criteria (100%) compared to the EFNS/PNS criteria (98.5% and 97%). Extended nerve conduction studies yielded slightly increased diagnostic sensitivity for both sets of criteria without significantly affecting specificity.In our patient populations, the 2010 EFNS/PNS criteria demonstrated higher sensitivity but slightly lower specificity compared to the AAEM criteria. Extended nerve conduction studies are advised to achieve slightly higher sensitivity while maintaining very high specificity. [ABSTRACT FROM AUTHOR]

Substantial concerns have been raised about the lack of an empirical basis for revisions made to the criteria for posttraumatic stress disorder (PTSD) in the DSM-5. Although researchers have examined the broader impact of these revisions on diagnostic prevalence, no study to date has examined the contribution of each individual revision. The current study sought to explore how each change in criteria and cluster structure affect frequency of PTSD diagnosis. Between July 2012 and October 2021, PTSD symptoms were collected at intake from child/parent reports (n = 65) at a pediatric mental health clinic and from adult patient reports (n = 322) at an outpatient mental health clinic. Compared to the frequency of PTSD diagnosis for adults based on DSM-IV criteria (73.6%), the frequency did not significantly increase with the addition of negative beliefs (74.8%), distorted thoughts (76.1%), and reckless or self-destructive behavior (74.2%), and increased significantly with a small effect with the addition of persistent negative emotional state (79.5%). The trend was similar for the youth sample across all new symptoms. A four-cluster structure diagnosed fewer individuals compared to a three-cluster structure across different sets of symptoms. The overall impact, however, was for DSM-5 to diagnose fewer adults but the same number of youths. Significant associations were found for age and sex with some new items. Findings add new concerns to the growing literature on problematic impacts of DSM-5 revisions to PTSD. [ABSTRACT FROM AUTHOR]

Purpose: Currently no guidance exists within the literature regarding diagnostic criteria or the long-term outcomes for paediatric patients with acute compartment syndrome (ACS). We conducted a retrospective cohort study reviewing all cases of paediatric ACS managed at a single tertiary referral centre with the aim of characterising the factors responsible for the eventual outcomes. Methods: The patient cohort was identified retrospectively by interrogating the hospital coding system for all paediatric patients between January 2014 and November 2022. The electronic emergency department, inpatient and operative notes as well as clinic letters for each patient were reviewed and data collected regarding presentation, associated injuries, management and subsequent complications plus length of follow-up. The data was analysed to determine if differences in presentation or management affected long term outcome. Results: The final cohort consisted of 34 patients with a mean age of ten years at the time of presentation. The mean time from presentation to fasciotomy was 27.6 h (range 3.0 – 66.6). There was an overall complication rate of 37.5% with a mean follow-up period of 21 months. Patients who had direct closure of their fasciotomy wounds had a significantly lower complications rate and fewer operations compared to those who healed via other wound coverage methods or secondary intention (p < 0.05). Conclusions: Significantly higher complication rates were observed in patients who were unable to have direct wound closure following emergency fasciotomy. This information may be utilised to rationalise long term treatment plans and in counselling of patients and parents. [ABSTRACT FROM AUTHOR]

Background and Aims: The International AIH Pathology Group (IAIH‐PG) put forward the new histological criteria of autoimmune hepatitis (AIH) in 2022, which have not undergone adequate verification. In this study, we verified the applicability of the new histological criteria in the population of Chinese patients with chronic liver disease, comparing it with the simplified criteria. Methods: The gold standard for diagnosis in all patients was based on histological findings, combined with clinical manifestations and laboratory tests and determined after a follow‐up period of at least 3 years. A total of 640 patients with various chronic liver diseases from multiple centres underwent scoring using the new histological criteria and the simplified criteria, comparing their diagnostic performance. Results: In this study, the new histological criteria showed a sensitivity of 73.6% and 100% for likely and possible AIH, with specificities of 100% and 69.0% respectively. The coincidence rates of possible AIH for the new histological criteria, simplified histological criteria and simplified score were 81.7%, 72.8% and 69.7% respectively. For likely AIH, the rates were 89.2%, 75.9% and 65.6% respectively. Based on the new histological criteria, all patients with AIH were correctly diagnosed. Specifically, 73.6% were diagnosed with likely AIH and 26.4% were possible AIH. Additionally, the simplified histological criteria achieved a diagnosis rate of 98.6% for AIH, while the simplified score could only diagnose 53.8% of AIH. Conclusions: Compared with the simplified score and simplified histological criteria, the sensitivity and specificity of the new histological criteria for AIH were significantly improved. The results indicate that the new histological criteria exhibit high sensitivity and specificity for diagnosing AIH in China. [ABSTRACT FROM AUTHOR]

The diagnosis of childhood schizophrenia was widely employed in the U.S. from the 1930s to the late 1970s. In this paper I will provide a history of the diagnosis. Some of the earliest publications on childhood schizophrenia outlined the notion that childhood schizophrenia had different types. I will outline the development of these types, outlining differing symptoms and causes associated with various types. I outline how different types of childhood schizophrenia were demarcated from one another primarily on age of onset and the type of psychosis which was believed to be present. I will outline how various child psychiatrists viewed the types of childhood schizophrenia posited by other child psychiatrists. I will outline the process of abandoning childhood schizophrenia. I use my history to challenge what I believe are misconceptions about childhood schizophrenia. Also, I will use my history to draw lessons for thinking about modern notions of autism. It shows potential problems around formulating psychiatric diagnoses around causes and how compromises might be needed to prevent those problems. Additionally, childhood schizophrenia shows that psychiatrists could formulate subtypes that are not based upon functioning levels and that we can conceive of subtypes as dynamic whereby someone can change which subtype they exhibit over time.

Abstract The aim of this study was to investigate the prevalence of diastasis recti abdominis (DRA) and to find the possible risk factors for DRA based on two diagnostic criteria among women in long-term postpartum period. A cross-sectional study was conducted on 1000 postpartum women at five different time points (3, 5, 10, 20, and 30 years after partum, respectively). Inter-recti distance (IRD) was assessed using ultrasound imaging, while basic data were collected through self-reported questionnaires. Two diagnostic criteria, IRD > 2 cm and IRD > 3 cm, were used to present the prevalence of DRA. Univariate and multivariate analyses were employed to explore the risk factors for DRA. When using the diagnostic criterion of IRD > 2 cm for DRA, the prevalence was 36%, 31%, 22%, 26%, and 30% at 3, 5, 10, 20, and 30 years postpartum, respectively. When using the diagnostic criterion of IRD > 3 cm for DRA, the prevalence was 13%, 8%, 6%, 8%, and 10%, respectively. The results revealed that higher body mass index (BMI) was a risk factor for DRA at 10 years postpartum (p = 0.000), bigger number of parturitions was a risk factor at 3, 5, and 10 years postpartum (p = 0.000, 0.004 and 0.000), twins was a risk factor at 3 years postpartum (p = 0.001), and diabetes was a risk factor at 20 and 30 years postpartum (P = 0.000 and 0.004). (1) The prevalence of DRA in the long-term postpartum period was high, especially when IRD > 2 cm was used as the diagnostic criterion. (2) Higher BMI, bigger number of parturitions, twins and diabetes were independently associated with higher odds of DRA at different long-term postpartum time points. (3) The diagnostic criterion for DRA should be further improved to avoid excessive clinical diagnosis and treatment. (1) This study elucidated the prevalence and risk factors associated with long-term postpartum DRA, thereby enhancing clinical awareness and advocating for early intervention and prevention measures to mitigate serious adverse outcomes. (2) This study presented the research results using two diagnostic criteria, increasing comparability with existing studies. In addition, discussions on reasonable diagnostic criterion for DRA were also conducted to avoid excessive clinical diagnosis and treatment.

Objective The exact relationship among atypical periprosthetic femoral fractures (APFFs), typical periprosthetic femoral fractures (PFFs), and atypical femur fractures (AFFs) remains unclear. This study aimed to investigate the prevalence of APFFs among PFFs and to identify the clinical characteristics, management, and prognosis that distinguish APFFs from typical PFFs and AFFs to further determine the relationship among these three fracture types. Methods In this retrospective study, we reviewed the clinical data of 117 consecutive patients who had PFFs after hip arthroplasty between January 2012 and December 2022 and further classified them into an APFF group and a typical PFF group according to the revised ASBMR diagnostic criteria for AFF. Moreover, patients who had subtrochanteric or femoral shaft fractures in the same period and met the diagnostic criteria for AFF were recruited and classified into the AFF group. Demographic information, minor features of AFF, comorbidities, history of medication usage, management, and complications were collected and compared among patients with typical PFFs, APFFs, and AFFs. Results Eleven PFFs were identified as APFFs, and the prevalence of APFFs among PFFs was 9.4%.

Abstract Background Although an increasing number of patients with Birt-Hogg-Dubé syndrome (BHD) are being recognized in China, clinical and genetic characteristics are not well-defined. In addition, revised diagnostic criteria for the Chinese population was proposed in 2023, we aimed to explore their utility in clinical practice at a rare lung disease center. Methods We retrospectively analyzed the data of 100 consecutive patients with BHD diagnosed according to the revised Chinese BHD criteria, encountered at the First Affiliated Hospital of University of Science and Technology of China from Jan 2017 to June 2023. Results There were 100 patients (including 63 females) from 65 unrelated families in Eastern China, mostly Anhui Province. The common manifestations were pulmonary cysts (99%), pneumothorax (60%), and skin lesions (77%). Renal cancer and renal angiomyolipoma were detected in 5 patients each. 37% of patients had no family history of BHD. In total, 25 FLCN germline mutations were detected, including 6 novel mutations. In addition to hotspot mutation c.1285delC/dupC (17%), the most common mutations were c.1015 C > T (16%), c.1579_1580insA (14%), and exons 1–3 deletion (11%) in FLCN. Higher risk of pneumothorax was associated with exons 1–3 deletion mutation and c.1177-5_1177-3de1CTC compared to the hotspot mutation c.1285dupC (91% [95% CI: 0.31, 46.82, p = 0.015] and 67% [95% CI: 0.35, 71.9, p = 0.302] vs. 30%, respectively). The average delay in diagnosis was 7.6 years after initial symptoms. Chinese diagnostic criteria were mostly consistent with typical pulmonary presentations with supportive genetic evidence. Conclusion In the Eastern Chinese region, patients with BHD present most commonly with pulmonary cysts associated with pneumothorax and skin lesions. However, low incidence of renal cancer along with unexpected renal angiomyolipoma was observed. Genotypic spectrum differed from that reported from other global regions, and genotype association of pneumothorax warrants further research. The revised Chinese criteria for BHD seem more appropriate in diagnosing BHD in Chinese patients.

Abstract Background and aims Despite concerns on the adverse health outcomes of sarcopenic obesity (SO), exploration regarding the applicability of different diagnostic criteria and the optimal screening methods is still lacking. This study aims to compare the prevalence and diagnostic agreement of SO under four diagnostic criteria in Chongming, Shanghai, China and assess the diagnostic value of nine screening methods for SO. Methods The study population included older people aged ≥ 65 years. The Asian Working Group for Sarcopenia-2019 (AWGS-2019) was used to diagnose sarcopenia. Obesity was defined using percentage of body fat (PBF), percent of body fat exceeding the 60th percentile (60% PBF), body mass index (BMI) and waist circumference (WC). The four diagnostic criteria for SO were AWGS + PBF, AWGS + 60% PBF, AWGS + BMI and AWGS + WC. Nine screening methods were the sarcopenia questionnaire [the questionnaire with five items to screen for sarcopenia (SARC-F), the addition of calf circumference to the SARC-F (SARC-CalF), and the addition of elderly age and BMI to the SARC-F (SARC-F + EBM)] combined with commonly used obesity indicators. Cohen’s kappa compared agreement between diagnostic criteria, whilst sensitivity, specificity, receiver operating characteristics (ROC) and area under the ROC curve (AUC) compared the diagnostic value of nine screening methods. Results A total of 1407 older people were enrolled. The prevalence of SO ranged from 0.3 to 9.9%. The highest agreement between AWGS + 60% PBF and AWGS + PBF. When the AWGS + PBF was used as the ‘gold standard’ (due to its high agreement and high prevalence), SARC-CalF + PBF had the highest AUC value, and SARC-F + BMI had the highest sensitivity. The recommended cut-off values for SARC-F + BMI are SARC-F ≥ 1 score and BMI ≥ 19.845 kg/m², and the recommended cut-off values for SARC-CalF + PBF are SARC-CalF ≥ 5 score and PBF ≥ 34.55%. Conclusion The prevalence of SO varied greatly amongst the four diagnostic criteria. AWGS + PBF is recommended for diagnosing SO in older people. SARC-F + BMI and SARC-CalF + PBF can be used as screening methods for SO.

Purpose of Review: To synthesize the current literature and contemporary landscape about promising advancements in clinical interventions targeting post-orgasmic illness syndrome (POIS). Recent Findings: PubMed search was performed, and articles were screened for relevance. 24 articles were deemed suitable for inclusion. Various pathophysiological mechanisms for POIS have been proposed, including immunologic hypersensitivity and sympathetic dysregulation. This syndrome may manifest post-intercourse, post-masturbation, or following spontaneous ejaculations, with flu-like symptoms persisting for a span of up to 7 days. Summary: Recurrent presentations of these symptoms significantly deteriorate both quality of life and sexual function in patients diagnosed with POIS, often leading to cognitive impairment and mood disturbances. While various therapeutic modalities have demonstrated efficacy in providing short-term relief, the management of acute episodes remains contentious. Furthermore, the dearth of longitudinal data hampers the establishment of definitive long-term management strategies for POIS sufferers. [ABSTRACT FROM AUTHOR]

NF2-related schwannomatosis (NF2; previously termed neurofibromatosis type 2) is a tumor-prone disorder characterized by development of multiple schwannomas and meningiomas. The diagnostic criteria of NF2 have been regularly revised. Clinical criteria for NF2 were first formulated at the National Institutes of Health Consensus Conference in 1987 and revised in 1990. Revised criteria were also proposed by the Manchester group in 1992 and by the National Neurofibromatosis Foundation (NNFF) in 1997. The 2011 Baser criteria improved the sensitivity of diagnostic criteria, particularly for patients without bilateral vestibular schwannomas. Revisions to the Manchester criteria were published in 2019, with replacement of “glioma” by “ependymoma,” removal of “neurofibroma,” addition of an age limit of 70 years for development of vestibular schwannomas, and introduction of molecular criteria, which led to the most widely used criteria. In 2022, the criteria were reviewed and updated by the international committee of NF experts. In addition to changes in diagnostic criteria, the committee recommended the use of “schwannomatosis” as an umbrella term for conditions that predispose to schwannomas. Each type of schwannomatosis was classified by the gene containing the disease-causing pathogenic variant. Molecular data from NF2 patients led to further clarification of the diagnostic criteria for NF2 mosaic phenotypes. Given all these changes, the diagnostic criteria of NF2 may be confusing. Herein, to help healthcare professionals who diagnose NF2 conditions in the clinical setting, we review the historical development of diagnostic criteria.

Abstract Background Bone marrow fibrosis (BMF) severely impacts both the quality of life and the efficacy of diagnostic procedures. However, the correlation between BMF and clinicopathological features, cytogenetic changes, and prognosis of newly diagnosed multiple myeloma (NDMM) remains unclear. This study determined the incidence, patient characteristics, and clinical outcomes of patients with NDMM with BMF. Methods The clinical data, histological features, and clinical outcomes of patients with NDMM were collected. Reticular fiber staining was performed on the enrolled cases, and the degree of reticular fiber overgrowth was graded. Patients with MF-2 and MF-3 were classified as the BMF+ group, and those with MF-0 and MF-1 were classified as the BMF- group, and BMF incidence was calculated. The differences in clinical data, histological features, and clinical outcomes between the BMF+ group and the BMF– group were compared. Results A consecutive series of 146 patients with NDMM were included. The incidence of MF-0, MF-1, MF-2, and MF-3 was 7.53% (11/146), 34.93% (51/146), 51.37% (75/146), and 6.16% (9/146), respectively. The incidence of BMF—MF-2 and MF-3—was 57.53% (84/146). A significant correlation was identified between the pattern of infiltration and BMF (P

Disorders of the gut-brain interaction (DGBIs) are presently classified into mutually exclusive anatomical area-related symptom-based categories according to the Rome IV criteria. The pathophysiology of visceral nociception, which contributes to the wide range of symptoms of DGBIs, involves complex psychobiological processes arising from the bidirectional interactions of multiple systems at the gut and brain levels, which affect symptom expression and illness behaviors. The attitude toward an illness and expression of pain and bowel habit vary across cultures with variable interpretation based on sociocultural beliefs, which may not tally with the medical definitions. Thus, psychological factors impact DGBI definitions, their severity and health care utilization. Due to the poor localization and multisegment referral of visceral pain, the anatomical site of pain may not correspond to the affected segment, and there may be a variable degree of overlap among symptoms. The somewhat restrictively defined Rome IV criteria assume one-to-one correlation of symptoms with underlying pathophysiology and ignore overlapping DGBIs, nonstandardized symptom categories, and change or shift in category over time. The microorganic nature of DGBIs resulting from systemic, metabolic or motility disorders, gut dysbiosis and inflammation are not addressed in the Rome IV criteria. Although there is a multidimensional clinical profile that does address these factors, it is not followed rigorously in practice. Threshold changes for diagnostic criteria or addition/deletion of symptoms leads to wide variation among different DGBI criteria resulting in uncertain comparability of results. Although the Rome IV criteria are excellent for research studies and therapeutic trials in homogenous populations, further improvement is needed for their wider applicability in clinical practice.

The problem of infective endocarditis (IE) remains relevant due to the high mortality rate and the development of severe complications. IE is a polyetiological disease, the occurrence and development of which can be caused by an extremely extensive list of pathogens, which is replenished almost annually. The pronounced clinical polymorphism of IE determines the importance of its early diagnosis, including the use of new medical technologies. Timely informing physicians about the modern principles of monitoring of patients with IE is of great practical importance. Part I of the article describes the clinical features, basic principles of diagnosis and differential diagnosis of IE, taking into account the recommendations of the European Society of Cardiology 2023.

An interest in studying the problem of heritable disorders (dysplasia) of connective tissue in Russia has remained at a high level since the early 90s of the 20th century. During this time, a large amount of clinical material has been accumulated. Several diagnostic algorithms have been developed on its basis. The aim of this review is to take a critical look at the proposed identification criteria, compare them, identify their limitations, assess compliance with the needs and expectations of practitioners, as well as to make a comparison with works on this topic in the world literature. We discuss the similarities and fundamental differences of the main concepts - the recommendations of the Russian Society of Cardiology (2009, 2013) and the Russian Scientific Medical Society of Therapists (2016, 2018, 2019). We suppose that the attention of practicing physicians should be focused on prognostically significant lesions of internal organs, rather than on external stigmas of dysembryogenesis.

Patients with MRSA detected in stool culture tests are often diagnosed with MSRA enteritis. However, uncertainty remains in the diagnostic criteria; therefore, we conducted epidemiological studies to define these cases.Patients and Methods: Patients who tested positive for MRSA by stool culture using selective media 48 h after admission to Kochi Medical School Hospital between April 1, 2012, and December 31, 2022, and did not meet the exclusion criteria were included. We defined MRSA enteritis (Group A) as cases that were responsive to treatment with vancomycin hydrochloride powder, had a Bristol Stool Scale of ≥ 5, and a stool frequency of at least three times per day; all others were MRSA carriers (Group B). Multivariate analysis was performed to risk factors associated with MRSA enteritis.Results: Groups A and B included 18 (25.4%) and 53 (74.6%) patients, respectively. Multivariate logistic regression analysis showed that a white blood cell count of > 10000/μL (odds ratio [OR], 5.50; 95% confidence interval [CI], 1.12– 26.9), MRSA count of ≥ 2+ in stool cultures (OR, 8.91; 95% CI, 1.79– 44.3), and meropenem administration within 1 month of stool specimen submission (OR, 7.47; 95% CI, 1.66– 33.6) were risk factors of MRSA enteritis.Conclusion: The case definitions reviewed for MRSA enteritis may be useful as diagnostic criteria. Keywords: MRSA enteritis, diagnostic criteria, white blood cell, MRSA counts in stool cultures, meropenem

Background: The conventional 20% threshold for hair diameter diversity (HDD), widely accepted for diagnosing androgenetic alopecia (AGA) in the vertex area, has not quantitatively analyzed. Objective: To validate the HDD 20% threshold for AGA and develop a refined, Korean-specific criterion. Methods: This study involved 240 male patients with AGA, categorized by the V stages of the basic and specific classification. Phototrichogram images of the vertex region were analyzed using Image J software for hair thickness measurement. Results: Receiver operating characteristic curve analysis determined the 45 μm hair diameter threshold as the most diagnostic for AGA, with an area under the curve value of 0.884 and a Youden index of 0.659. Optimal AGA diagnosis was achieved when over 21% of hair had a diameter of ≤45 μm. Limitations: Restriction to Korean male limits its applicability to a broader population, and using a specific hair diameter threshold does not account for individual variations in hair characteristics. Conclusion: The study validates the conventional HDD 20% threshold and proposes a more appropriate 45 μm threshold for Korean males, beyond the 40 μm. It concludes that while the HDD 20% remains a key method for early detection of vertex AGA, the definition of thin hair should be ethnicity-specific.

Background: Anastomotic stricture (AS) is a common complication following rectal cancer surgery with anastomosis, but its diagnosis and management pose significant challenges due to the lack of standardized diagnostic criteria. We present a case highlighting the complexities encountered in diagnosing and managing occult AS post-rectal cancer surgery. Case presentation: A 51-year-old male patient presented with symptoms suggestive of AS following robot-assisted laparoscopic low anterior resection for rectal adenocarcinoma. Despite conventional evaluations, including colonoscopy, digital rectal examination, and radiography, AS was not identified. Following prolonged and ineffective treatment for suspected conditions such as low anterior resection syndrome (LARS), the patient underwent anal dilatation, resulting in significant symptom improvement. Conclusions: This case underscores the challenges associated with diagnosing and managing occult AS following rectal cancer surgery. The absence of standardized diagnostic criteria and reliance on conventional modalities may lead to underdiagnosis and inadequate treatment. A comprehensive diagnostic approach considering intestinal diameter, elasticity, and symptoms related to difficult defecation may enhance diagnostic accuracy. Further research is needed to refine the diagnostic and therapeutic strategies for occult AS. [ABSTRACT FROM AUTHOR]

Objective Design Setting Population Methods Main Outcome Measures Results Conclusions To identify factors associated with neonatal respiratory distress (NRD) in early Gestational diabetes mellitus (eGDM).Nested case–control analysis of the TOBOGM trial.Seventeen hospitals: Australia, Sweden, Austria and India.Pregnant women, <20 weeks' gestation, singleton, GDM risk factors.Women with GDM risk factors completed an oral glucose tolerance test (OGTT) before 20 weeks: those with eGDM (WHO‐2013 criteria) were randomised to immediate or deferred GDM treatment. Logistic regression compared pregnancies with/without NRD, and in pregnancies with NRD, those with/without high‐dependency nursery admission for ≤24 h with those admitted for >24 h. Comparisons were adjusted for age, pre‐pregnancy body mass index, ethnicity, smoking, primigravity, education and site. Adjusted odds ratios (95% CI) are reported.NRD definition: ≥4 h of respiratory support (supplemental oxygen or supported ventilation) postpartum. Respiratory distress syndrome (RDS): Supported ventilation and ≥24 h nursery stay.Ninety‐nine (12.5%) of 793 infants had NRD; incidence halved (0.50, 0.31–0.79) if GDM treatment was started early. NRD was associated with Caesarean section (2.31, 1.42–3.76), large for gestational age (LGA) (1.83, 1.09–3.08) and shorter gestation (0.95, 0.93–0.97 per day longer). Among NRD infants, >24 h nursery‐stay was associated with higher OGTT 1‐h glucose (1.38, 1.08–1.76 per mmol/L). Fifteen (2.0%) infants had RDS.Identifying and treating eGDM reduces NRD risk. NRD is more likely with Caesarean section, LGA and shorter gestation. Further studies are needed to understand the mechanisms behind this eGDM complication and any long‐term effects.

Background/Objectives: Recently, an update of the Duke criteria for the diagnosis of infectious endocarditis has been published: the 2023 Duke-ISCVID criteria. To gain an insight into which proportion of patients are affected by the new criteria, and which criteria might be the most relevant for the expected increase in sensitivity, we analysed data from a registry of cardiovascular infections. Methods: The 2023 Duke-ISCVID criteria were applied to patients who were diagnosed with and treated for endocarditis after having been classified as "possible" endocarditis according to the 2015 ESC Modified Duke criteria. In patients thus newly classified as "definite endocarditis", diagnostic factors leading to this reclassification were described. Results: Of 397 patients, 48 (12%) did not fulfil the definition "definite infectious endocarditis" according to the 2015 ESC Modified Duke criteria. Of these, six (13%) fulfilled the definition when the 2023 Duke-ISCVID criteria were applied. A main factor triggering this reclassification was the consideration of microorganisms identified using valve PCR. Conclusions: As expected, the sensitivity of the new 2023 Duke-ISCVID criteria is increased in this cohort, mainly through the incorporation of new diagnostic methods in the criteria. Further studies are required to assess the effect on specificity in detail. [ABSTRACT FROM AUTHOR]

Aim: To establish cut‐off values for anti‐Müllerian hormone (AMH) and antral follicle count (AFC) in the diagnostic criteria for polycystic ovary syndrome (PCOS) applicable to the Japan Society of Obstetrics and Gynecology (JSOG) 2024 criteria and the Rotterdam/International Evidence‐Based Guideline for the assessment and management of PCOS (IEBG) 2023 criteria based on a nationwide survey, respectively, taking into account age, assays, and structure of the diagnostic criteria. Methods: Data were collected for 986 PCOS cases and 965 control cases using a national survey in Japan and used to establish cut‐off values for AMH and AFC. Results: Serum AMH levels were significantly higher in the PCOS group compared to the control group. Serum AMH showed a significant negative correlation with age and significant positive correlation with AFC in both groups. In multiple regression analysis, serum AMH level was independently affected by AFC and total testosterone. AMH cut‐off values suitable for the JSOG 2024 criteria and the Rotterdam/IEBG 2023 criteria were separately established for the 20–29 and 30–39 years of age groups, respectively, and for Access, Lumipulse and Elecsys/ECLusys, respectively. AFC cut‐off values suitable for the JSOG 2024 criteria and Rotterdam/IEBG 2023 criteria were also established separately. AFC exhibited statistically greater variability than AMH. Conclusion: The serum AMH level is the biochemical representation of ovarian findings in PCOS and considered objective and highly reliable. Therefore, it could serve as a surrogate for AFC as a marker of polycystic ovarian morphology in diagnostic criteria. [ABSTRACT FROM AUTHOR]

Key points: Silent sinus syndrome (SSS) and chronic maxillary atelectasis (CMA) represent an overlapping clinical entity, both likely lying on the spectrum of one disease process.There is widespread inconsistency of diagnosis in the literature of reported cases of SSS and CMA.We propose a novel, comprehensive staging system to simplify diagnosis and inform management.

Background: One of the criticisms of the operational/diagnostic criteria, generalised since DSM‐III, has been that they were shaped solely to achieve the best inter‐peer reliability with no considerations for validity. This does not fully reflect reality since throughout the development of the criteria, there was an effort to define and fulfil some validity requirements. However, despite several attempts to create alternative diagnostic systems, there is still a widespread misunderstanding of the epistemological foundations that support this paradigm. Methods: In this article, we intend to analyse the epistemological context in which the operational criteria (OC) emerged and some of the validation processes they have undergone since their conception. Results: On the epistemological basis of these operational criteria (OC) the influence of Hempel has been widely discussed. However, the group from St. Louis and, also the DSM‐III editors, never openly acknowledged his role and his contribution and revealed other influences such as other medical specialties (that used and validated several OC in the diagnosis of their diseases). On the other hand, contrary to what has often been mentioned there has been a continuous attempt to validate the OC since their conception. In the implementation and development of the operational paradigm, a more instrumental trend was followed, focused on utility, but with successive attempts to achieve realistic validity by searching for biological or psychological causality. The methodologies were initially expert‐driven and gradually more data‐driven and included some variables external to the construct itself, such as familial aggregation, diagnostic consistency over time, prognostic and other psychometric measures.

Purpose of Review: Myelin oligodendrocyte glycoprotein antibody disease (MOGAD) is a distinct neuroinflammatory condition characterized by attacks of optic neuritis, transverse myelitis, and other demyelinating events. Though it can mimic multiple sclerosis and neuromyelitis optica spectrum disorder, distinct clinical and radiologic features which can discriminate these conditions are now recognized. This review highlights recent advances in our understanding of clinical manifestations, diagnosis, and treatment of MOGAD. Recent Findings: Studies have identified subtleties of common clinical attacks and identified more rare phenotypes, including cerebral cortical encephalitis, which have broadened our understanding of the clinicoradiologic spectrum of MOGAD and culminated in the recent publication of proposed diagnostic criteria with a familiar construction to those diagnosing other neuroinflammatory conditions. These criteria, in combination with advances in antibody testing, should simultaneously lead to wider recognition and reduced incidence of misdiagnosis. In addition, recent observational studies have raised new questions about when to treat MOGAD chronically, and with which agent. Summary: MOGAD pathophysiology informs some of the relatively unique clinical and radiologic features which have come to define this condition, and similarly has implications for diagnosis and management. Further prospective studies and the first clinical trials of therapeutic options will answer several remaining questions about the peculiarities of this condition. [ABSTRACT FROM AUTHOR]

However, the correlation between BMF and clinicopathological features, cytogenetic changes, and prognosis of newly diagnosed multiple myeloma (NDMM) remains unclear. This study determined the incidence, patient characteristics, and clinical outcomes of patients with NDMM with BMF. Methods: The clinical data, histological features, and clinical outcomes of patients with NDMM were collected. Reticular fiber staining was performed on the enrolled cases, and the degree of reticular fiber overgrowth was graded. Patients with MF-2 and MF-3 were classified as the BMF+ group, and those with MF-0 and MF-1 were classified as the BMF- group, and BMF incidence was calculated. The differences in clinical data, histological features, and clinical outcomes between the BMF+ group and the BMF– group were compared. Results: A consecutive series of 146 patients with NDMM were included. The incidence of MF-0, MF-1, MF-2, and MF-3 was 7.53% (11/146), 34.93% (51/146), 51.37% (75/146), and 6.16% (9/146), respectively. The incidence of BMF—MF-2 and MF-3—was 57.53% (84/146). A significant correlation was identified between the pattern of infiltration and BMF (P < 0.001). In the BMF- group, the distribution of cases with interstitial, nodular, and diffuse infiltration of plasma cells was 16 (25.8%), 21 (33.9%), and 25 (40.3%), respectively. Conversely, in the BMF+ group, these values for interstitial, nodular, and diffuse tumor cells were 9 (10.7%), 15 (17.9%), and 60 (71.4%). Furthermore, BMF was associated with a diffuse infiltration pattern. The overall survival (OS) of the BMF+ group (39.1 months; 95% confidence interval [CI]: 34.0–44.3) was lower than that of the BMF- group (45.4 months; 95% CI: 39.5–51.3), but there was no significant difference between the two groups (P = 0.221). Univariate and multivariate analyses showed that the BMF+ status was not associated with OS in patients with NDMM (P = 0.381 and P = 0.748, respectively). Conclusions: Our findings suggest that BMF is linked to a diffuse infiltration pattern, and its occurrence is not related to the prognosis of patients with NDMM, providing a basis for further exploring the BMF value in NDMM diagnosis and treatment.

Introduction: Recent diagnostic criteria for optic neuritis include T2-hyperintensity of the optic nerve (ON), even without associated contrast enhancement. However, isolated ON-T2-hyperintensity is a nonspecific finding found in any optic neuropathy or severe retinopathy. We applied the 2022 optic neuritis diagnostic criteria to a cohort of patients with noninflammatory optic neuropathy and ON-T2-hyperintensity in at least one eye, to assess the rate of optic neuritis misdiagnosis using these criteria. Methods: Retrospective study of consecutive patients who underwent brain/orbit MRI with/without contrast between 07/01/2019 and 06/30/2022. Patients with ON-T2-hyperintensity in at least one eye were included. The 2022 optic neuritis diagnostic criteria were applied to patients with noninflammatory optic neuropathies who had an ophthalmologic examination available for review. Results: Of 150 patients included, 85/150 had compressive optic neuropathy; 32/150 had glaucoma; 12/150 had papilledema; 8/150 had hereditary (3), radiation-induced (3), nutritional (1), traumatic (1) optic neuropathies (none fulfilled the criteria); 13/150 had ischemic optic neuropathy and 4 fulfilled the criteria as definite optic neuritis due to contrast enhancement of the ON head. Seven additional patients would have satisfied the diagnostic criteria if red flags for alternative diagnoses had been overlooked. Discussion: The application of the 2022 optic neuritis diagnostic criteria in patients with noninflammatory optic neuropathy and ON-T2-hyperintensity in at least one ON resulted in misdiagnosis of optic neuritis in only 4 patients because of ON head enhancement, all with nonarteritic anterior ischemic optic neuropathy. Neuro-ophthalmologic evaluation and exclusion of the ON head as a location in the MRI criteria would have prevented optic neuritis misdiagnosis in our study. [ABSTRACT FROM AUTHOR]

Key Clinical Message: Rheumatic heart disease is a preventable disease. Patients may not present with a typical history of sore throat and polyarthritis but may present with Sydenham's chorea. We should not rely completely on clinical findings to rule out carditis. Echocardiography should be done to rule out subclinical carditis. Sydenham's chorea is a major manifestation of rheumatic fever. It occurs primarily in children and is seen rarely after the age of 20 years. We describe a 16‐year‐old girl who presented with purposeless involuntary movements of her upper and lower limbs. Laboratory blood reports showed raised erythrocyte sedimentation rate and anti‐streptolysin O. 2D Doppler Echocardiography confirmed subclinical carditis, thickened mitral and aortic valve with mild mitral regurgitation. She was managed as Acute Rheumatic Fever with oral Phenoxymethyl penicillin and Carbamazepine. At the latest follow‐up interviewing the caregiver, the patient had no sequelae. Early diagnosis is key to preventing late consequences of acute rheumatic fever and rheumatic heart disease. Sydenham's chorea is a rare presentation of acute rheumatic fever. The absence of clinical carditis does not rule out carditis. [ABSTRACT FROM AUTHOR]

Objective: There is debate surrounding how to differentiate between anorexia nervosa (AN) and atypical AN (atypAN) as diagnostic entities, and whether a distinction based on BMI is warranted. Better understanding eating disorder (ED) and emotional symptoms across atypAN and AN subtypes [AN‐restricting (AN‐R), AN‐binge/purge (AN‐BP)], with and without controlling for BMI, can elucidate how atypAN differs from AN subtypes and whether there is a basis for a BMI cut‐off. Methods: 1810 female patients at an ED treatment centre completed intake surveys. ANCOVAs assessed differences across AN‐R (n = 853), AN‐BP (n = 726), and atypAN (n = 231) groups on ED, depressive, and anxiety symptoms, anxiety sensitivity, experiential avoidance, and mindfulness, with and without controlling for BMI. Results: Relative to AN‐R, atypAN and AN‐BP groups endorsed significantly higher ED and depressive symptoms, anxiety sensitivity, experiential avoidance, and significantly lower mindfulness (all p < 0.001), but atypAN and AN‐BP groups did not differ from one another. When controlling for BMI, all previously significant differences between atypAN and AN‐R did not remain significant. Conclusion: Individuals with atypAN who have a higher BMI experience more pronounced ED and emotional symptoms, suggesting that relying solely on BMI as a marker of illness severity may be problematic. Highlights: Atypical anorexia nervosa (atypAN) describes individuals who meet all of the criteria for AN, but who, despite significant weight loss, have a BMI within or above the 'normal' weight range.Individuals with atypAN endorsed more severe eating disorder and emotional symptoms than individuals with AN‐restricting subtype, and the higher BMI of individuals with atypAN accounted for these differences.atypAN symptoms may not only be just as severe as those of AN despite their higher weight, but may be exacerbated by weight stigma and greater body image concerns because of their higher weight.

BACKGROUND: There is no specificity in the clinical presentation of hemophagocytic lymphohistiocytosis (HLH). OBJECTIVE: To study some clinical, etiological, and prognostic features of HLH to improve the clinical understanding of the disease. METHODS: Retrospective analysis of the clinical data of 125 patients with HLH admitted to our hospital from June 2015 to August 2021, including clinical characteristics, laboratory indicators, and survival period. Statistical analysis was performed from the overall group of study indicators, which included population, children, and adults. RESULTS: In the whole population, sex, age, blood myoglobin, and NK cell ratio of M-HLH and non-M-HLH patients (P < 0.05), serum albumin, and direct bilirubin were independent correlates of M-HLH. In the pediatric group, age and the proportion of NK cells were significantly different between M-HLH and non-M-HLH patients (P < 0.05). Multivariate Logistic regression analysis showed that all factors were not significantly associated with M-HLH. The associated regression analysis showed that all factors were not significantly associated with M-HLH. ROC curve analysis showed that the best predictive value of NK cell percentage for M-HLH diagnosis in the overall population was 4.96% in the pediatric group and 4.96% in the adult group. The best predictive value for M-HLH diagnosis was 2.08%. The univariate analysis showed that platelet count, alanine aminotransferase, aspartate aminotransferase, serum albumin, direct bilirubin and indirect bilirubin affected prognosis; COX regression showed that none of these factors had a significant relationship. The overall median survival time was 20.7 months in the adult group, 44.3 months in non-M-HLH patients, and 7.73 months in M-HLH patients (p = 0.011); univariate analysis showed that platelet count and serum albumin level affected prognosis; COX regression results in serum albumin level was an independent risk factor for prognosis. CONCLUSION: The survival rate of non-M-HLH was significantly better than that of M-HLH; the proportion of NK cells had predictive value for the diagnosis of M-HLH; in the general population, non-M-HLH was more likely to have abnormal liver function than M-HLH: lower platelet count and serum albumin level were associated with poor prognosis, and the lower the platelet count and serum albumin level, the worse the prognosis: in addition, adults with lower serum albumin levels are also associated with poor prognosis.

Purpose: This study aimed to elucidate the relationship between diurnal masseter muscle activity and awareness of diurnal awake bruxism (d-AB) by conducting a comparative analysis of electromyographic (EMG) data from individuals with and without awareness of diurnal awake bruxism (d-AB), utilizing EMG data gathered from multiple subjects. Methods: Unilateral masseter electromyography (EMG) recordings were performed during the daytime using an ultraminiature wearable EMG device. A total of 119 participants (59 with awareness of diurnal tooth clenching [d-TC] and 60 without awareness of d-TC) were included. Waveforms longer than 0.25 s with the two amplitude conditions, exceeding twice the baseline and >5% of maximum voluntary clenching, were extracted. In addition, the number of bursts and episodes (groups of bursts), burst duration, and burst peak amplitude were calculated for each participant. Results: There were no significant differences in the EMG parameters between the groups with and without awareness of d-TC. Additionally, the frequency distribution of the number of EMG waveforms exhibited wide ranges and substantial overlap between the two groups. Conclusions: The variability in the number of bursts and episodes, burst peak amplitude, and burst duration among subjects suggests the need for an objective classification of d-AB severity based on EMG values. The absence of significant differences and large overlap in frequency distributions between the groups with and without awareness of d-TC indicate difficulty in predicting muscle activity solely based on awareness of d-AB.

Background: Ventilator-associated pneumonia (VAP) is a prevalent and grave hospital-acquired infection that affects mechanically ventilated patients. Diverse diagnostic criteria can significantly affect VAP research by complicating the identification and management of the condition, which may also impact clinical management. Objectives: We conducted this review to assess the diagnostic criteria and the definitions of the term "ventilator-associated" used in randomised controlled trials (RCTs) of VAP management. Search methods: Based on the protocol (PROSPERO 2019 CRD42019147411), we conducted a systematic search on MEDLINE/PubMed and Cochrane CENTRAL for RCTs, published or registered between 2010 and 2024. Selection criteria: We included completed and ongoing RCTs that assessed pharmacological or non-pharmacological interventions in adults with VAP. Data collection and synthesis: Data were collected using a tested extraction sheet, as endorsed by the Cochrane Collaboration. After cross-checking, data were summarised in a narrative and tabular form. Results: In total, 7,173 records were identified through the literature search. Following the exclusion of records that did not meet the eligibility criteria, 119 studies were included. Diagnostic criteria were provided in 51.2% of studies, and the term "ventilator-associated" was defined in 52.1% of studies. The most frequently included diagnostic criteria were pulmonary infiltrates (96.7%), fever (86.9%), hypothermia (49.1%), sputum (70.5%), and hypoxia (32.8%). The different criteria were used in 38 combinations across studies. The term "ventilator-associated" was defined in nine different ways. Conclusions: When provided, diagnostic criteria and definitions of VAP in RCTs display notable variability. Continuous efforts to harmonise VAP diagnostic criteria in future clinical trials are crucial to improve quality of care, enable accurate epidemiological assessments, and guide effective antimicrobial stewardship.

Objectives: To present a rare case of neonatal lupus erythematosus (NLE) associated with suspected hemophagocytic lymphohistiocytosis (HLH) or macrophage activation syndrome (MAS). Case presentation: A female infant weighing 2,995 g was born to a mother without medical history of any disease. At birth, the patient had erythematous papules on her face and trunk. She was admitted at 1 day of age with elevated C-reactive protein levels. The patient was diagnosed with NLE based on the presence of anti-Ro/SSA and anti-La/SSB antibodies. Thereafter, it became clear that the antibody levels in her mother were also elevated. At 20 days of age, the infant showed elevated transaminases, ferritin, triglyceride, and soluble interleukin-2 receptor levels. Although HLH or MAS was suspected, she did not fulfill the diagnostic criteria. Thereafter, these abnormal values spontaneously improved, and the skin rash improved with the use of topical steroids. The patient was discharged at 39 days of age. At 1 year of age, the patient's growth and development were normal. Conclusion: NLE should be considered in infants with an unexplained skin rash at birth. When a diagnosis is made, close observation of the infant's clinical features is needed to determine whether they will develop HLH or MAS. [ABSTRACT FROM AUTHOR]

Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) is a chronic, debilitating disease characterised by a wide range of symptoms that severely impact all aspects of life. Despite its significant prevalence, ME/CFS remains one of the most understudied and misunderstood conditions in modern medicine. ME/CFS lacks standardised diagnostic criteria owing to variations in both inclusion and exclusion criteria across different diagnostic guidelines, and furthermore, there are currently no effective treatments available. Moving beyond the traditional fragmented perspectives that have limited our understanding and management of the disease, our analysis of current information on ME/CFS represents a significant paradigm shift by synthesising the disease’s multifactorial origins into a cohesive model. We discuss how ME/ CFS emerges from an intricate web of genetic vulnerabilities and environmental triggers, notably viral infections, leading to a complex series of pathological responses including immune dysregulation, chronic inflammation, gut dysbiosis, and metabolic disturbances. This comprehensive model not only advances our understanding of ME/CFS’s pathophysiology but also opens new avenues for research and potential therapeutic strategies. By integrating these disparate elements, our work emphasises the necessity of a holistic approach to diagnosing, researching, and treating ME/CFS, urging the scientific community to reconsider the disease’s complexity and the multifaceted approach required for its study and management.

Aim: The diagnosis of drug‐induced liver injury (DILI) is challenging. We modified the revised electronic version of the Roussel Uclaf Causality Assessment Method (RUCAM) for the diagnosis of DILI (RECAM), the scoring system developed in US and Spanish cohorts in 2022, and developed RECAM‐J 2023 to align with the clinical practice in Japan. In the current study, we introduce RECAM‐J 2023 and verify its performance in the context of Japanese patients with DILI. Methods: After translation of RECAM into Japanese, modifications were made to develop RECAM‐J 2023 without any alteration to the scores. To examine the validity and performance of RECAM‐J 2023, clinical information on DILI and non‐DILI cases in Japan were retrospectively collected. The diagnosis of DILI was made by expert's decision. Then we scored each case using RECAM‐J 2023, and calculated area under curve (AUC) values for identification for DILI. Results: We collected data from 538 DILI and 128 non‐DILI cases. The sum of highly probable (HP) and probable (PR) cases categorized by RECAM‐J 2023 were only 206 (38%) in DILI cases. As the primary cause of low scores was the deduction with missing hepatitis virus markers, which is unlikely to be an issue in prospective applications, we rescored without these deductions. At this time, the sum of HP and PR was raised to 421 (78%). The AUCs of RECAM‐J 2023 without deductions were 0.70 and 0.88 for identifying at least HP, and at least PR, respectively. Conclusion: RECAM‐J 2023, when prospectively used without any missing hepatitis virus markers, provides acceptable performance for identifying at least PR DILI cases in Japanese daily clinical practice.
