Abstract
Metabolic dysfunction-associated steatotic liver disease (MASLD) is the leading cause of chronic liver disease that affects over 30% of the world's population. For decades, the heterogeneity of non-alcoholic fatty liver disease (NAFLD) has impeded our understanding of the disease mechanism and the development of effective medications. However, a recent change in the nomenclature from NAFLD to MASLD emphasizes the critical role of systemic metabolic dysfunction in the pathophysiology of this disease and therefore promotes the progress in the pharmaceutical treatment of MASLD. In this review, we focus on the mechanism underlying the abnormality of hepatic lipid metabolism in patients with MASLD, and summarize the latest progress in the therapeutic medications of MASLD that target metabolic disorders.

Abstract
BACKGROUND & AIMS Metal elements have been associated with a wide range of clinical outcomes. The available epidemiological evidence for these associations is often inconsistent and suffers from confounding and reverse causation. We aimed to explore the broad clinical effects of varying blood metal element levels and possible underlying mechanisms. METHODS We performed a two-sample Mendelian randomization (MR) analysis by using metal element-associated genetic loci as instrumental variable to evaluate the causal associations between blood metal element levels and 1050 disease outcomes in a UK Biobank cohort. A total of 408,910 White British participants were enrolled in the analysis. We further used the metal element-related genes and disease-related genes to construct a protein-protein interaction (PPI) network. RESULTS Eight metal elements were associated with 63 diseases in total. Notably, we found nine pairs of suggestive evidence between two different metal elements for the same disease. Selenium and lead share some of the associated clinical outcomes, including diabetes mellitus, type 2 diabetes, lymphoid leukemia, and acute pharyngitis. Lead and zinc share the associated disease of acquired hypothyroidism. Iron and copper share the associated disease of arthropathies. Copper and zinc share the associated disease of occlusion of cerebral arteries. Calcium and zinc share the associated disease of arthropathies. In addition, the PPI network provided potential links between metal elements and disease outcomes at the genetic level. CONCLUSIONS Our MR study of eight metal elements comprehensively characterized their shared and unique clinical effects, highlighting their potential causal roles in multiple diseases. Given the modifiable nature of blood metal elements and the potential for clinical interventions, these findings warrant further investigation.

Abstract
Myotonic dystrophy type 2 (MD2) is a multisystem disease, predominantly affecting the proximal limb muscles, eyes, endocrine organs, heart and intestines. Longterm asymptomatic creatine kinase (hyper-CKemia) of more than 20 years duration, in association with hyperlipidemia and diabetes, as a manifestation of MD2 has not been reported. A 52-year-old female with a history of hyper-CKemia since the age of 32 years associated with diabetes, hyperlipidemia and hyperuricemia, developed anginal chest pain and proximal muscle weakness together with clinical myotonia when opening the fists at age 51 years. Examination revealed a left anterior hemiblock, sensorimotor neuropathy, extensive myotonic discharges on needle electromyography (EMG) and a CCTG-expansion of 134 bp on the ZNF9 gene. The family history was positive for hyper-CKemia and muscle weakness. In addition, over the previous years, she had developed vesico-ureteral reflux, cutaneous melanoma, renal cysts, cervix dysplasias, thrombocytosis, cataracts, arterial hypertension, heterozygous Factor V Leiden mutation, cholecystolithiasis, multiple ovarial cysts and vitamin D deficiency. Asymptomatic, long-term hyper-CKemia in association with multisystem disease should raise the suspicion of a MD2. Rare manifestations of MD2 may be thrombocytosis, hyperuricemia, vesico-ureteral reflux, gallstones, hypertension and cyst formation. In patients with asymptomatic hyper-CKemia, needle EMG should be considered. Myotonic dystrophy type 2 may take a mild course over many years if the CCTG-expansion is short.

Abstract
Background The clinical presentation of Langerhans cell histiocytosis (LCH) is heterogeneous ranging from single-organ involvement to systemic disease causing substantial morbidity and mortality. We describe an unusual course of severe multisystem LCH with spontaneous remission. Case Presentation We report on a 45-year-old Caucasian woman with cervical cancer, FIGO stage IVB. Five months after the end of combined radiochemotherapy and brachytherapy, the patient was readmitted because of severe dysuria. Sterile leukocyturia was seen, and cystoscopy revealed only 3 unspecific small mucosal lesions compatible with postradiation cystitis. Incidentally, a computed tomography (CT) scan of the body showed diffuse micronodular and cystic lesions in lungs and hypodense lesions in the liver. Biopsies revealed infiltrations of CD1a and Langerin (CD207)-positive histiocytes in the lung, liver, and bladder. Additionally, positron emission tomography-CT (PET-CT) was compatible with bone involvement. Retrospective analysis revealed that the increase in alkaline phosphatase might have been a surrogate of bone marrow infiltration with osseous activity. Repeated pneumothoraces occurred, and only one course of vinblastine-prednisolone could be applied. Despite ongoing tobacco consumption and without further therapy, PET-CT showed considerable remission 2 months later. However, despite stable remission, documented by serial PET and conventional CT scans, persistent infiltration of the bladder by Langerhans histiocytes could still be demonstrated 17 months later. Unfortunately, cervical cancer recurred and progressed. Conclusion Multisystem LCH may rapidly occur, may be oligosymptomatic and, even in high-risk cases, remission without specific therapy might occur. Whether alkaline phosphatase might be a surrogate to monitor osseous disease activity has to be further explored.

Abstract
BACKGROUND Pompe disease is an autosomal recessive disorder caused by deficiency of the lysosomal glycogen-hydrolyzing enzyme acid α-glucosidase (GAA). The adult-onset form, late-onset Pompe disease (LOPD), has been characterized by glycogen accumulation primarily in skeletal, cardiac, and smooth muscles, causing weakness of the proximal limb girdle and respiratory muscles. However, increased scientific study of LOPD continues to enhance understanding of an evolving phenotype. PURPOSE To expand our understanding of the evolving phenotype of LOPD since the approval of enzyme replacement therapy (ERT) with alglucosidase alfa (Myozyme™/Lumizyme™) in 2006. METHODS All articles were included in the review that provided data on the charactertistics of LOPD identified via the PubMed database published since the approval of ERT in 2006. All signs and symptoms of the disease that were reported in the literature were identified and included in the review. RESULTS We provide a comprehensive review of the evolving phenotype of LOPD. Our findings support and extend the knowledge of the multisystemic nature of the disease. CONCLUSIONS With the advent of ERT and the concurrent increase in the scientific study of LOPD, the condition once primarily conceptualized as a limb-girdle muscle disease with prominent respiratory involvement is increasingly recognized to be a condition that results in signs and symptoms across body systems and structures.

Abstract
Non-alcoholic fatty liver disease (NAFLD) is one of the most common comorbidities associated with overweight and metabolic syndrome (MetS). Importantly, NAFLD is one of its most dangerous complications because it can lead to severe liver pathologies, including fibrosis, cirrhosis and hepatic cellular carcinoma. Given the increasing worldwide prevalence of obesity, NAFLD has become the most common cause of chronic liver disease and therefore is a major global health problem. Currently, NAFLD is predominantly regarded as a hepatic manifestation of MetS. However, accumulating evidence indicates that the effects of NAFLD extend beyond the liver and are negatively associated with a range of chronic diseases, most notably cardiovascular disease (CVD), diabetes mellitus type 2 (T2DM) and chronic kidney disease (CKD). It is becoming increasingly clear that these diseases are the result of the same underlying pathophysiological processes associated with MetS, such as insulin resistance, chronic systemic inflammation and dyslipidemia. As a result, they have been shown to be independent reciprocal risk factors. In addition, recent data have shown that NAFLD actively contributes to aggravation of the pathophysiology of CVD, T2DM, and CKD, as well as several other pathologies. Thus, NAFLD is a direct cause of many chronic diseases associated with MetS, and better detection and treatment of fatty liver disease is therefore urgently needed. As non-invasive screening methods for liver disease become increasingly available, detection and treatment of NAFLD in patients with MetS should therefore be considered by both (sub-) specialists and primary care physicians.

Abstract
BACKGROUND The IgG4-related disease describes a new multisystem disorder, which can also be manifested in the orbit. This syndrome is characterized by a multifocal chronic fibroinflammation with high levels of plasma cells expressing IgG4. CASE REPORT This article reports the case of a patient with advanced bilateral tumors of the upper eyelid and orbit. The diagnosis of IgG4-related disease was only revealed after many years and after many biopsies of the tumors had been carried out. The initiation of a systemic steroid therapy led to a rapid reduction of the tumors and an improvement in the general condition of the patient.

Abstract
Osteopontin (OPN) acts as an osteoclast activator, a proinflammatory cytokine, and a chemokine attracting histiocytes/monocytes and is abundantly expressed in Langerhans cell histiocytosis (LCH). We investigated whether serum OPN levels are related to disease types in LCH. Fifty-eight newly diagnosed LCH patients were studied; eight with risk organ (liver, spleen and/or hematopoietic) involvements positive multisystem (MS+) disease, 27 with risk organ involvement negative multisystem (MS-) disease and 23 with single system (SS) disease. Pediatric patients with non-inflammatory disease (n=27) were used as controls. All of patients with MS+ disease were younger than 3 years. Serum OPN levels and 44 kinds of humoral factors were measured by ELISA and Bio-Plex suspension array system, respectively. In the patients younger than 3 years, the median serum OPN level (interquartile range) was 240.3 ng/ml (137.6-456.0) in MS+ (n=8); 92.7 ng/ml (62.0-213.8) in MS- (n=14) and 72.5 ng/ml (55.6-94.0) in SS (n=9) and 74.4 ng/ml (42.2-100.0) in control (n=12). The OPN values were significantly higher in the MS+ group than the MS-, SS and control groups (p=0.044, p=0.001 and p=0.002, respectively), but not different between the MS-, SS and control groups. In the patients older than 3 years, the median level of serum OPN (IQR) was 56.2 ng/ml (22.9-77.5) in MS- (n=13), 58.9 ng/ml (31.0-78.7) in SS (n=14) and 41.9 (28.9-54.1) in control (n=15). These values did not differ significantly between each group. The serum OPN levels were positively correlated with the serum IL-6, CCL2, IL-18, IL-8 and IL-2 receptor concentration. OPN may be involved in risk organ dissemination and poor prognosis of LCH through the function as inflammatory cytokine/chemokine.
