Abstract
OBJECTIVE The main purpose of this study was to explore the diagnostic performance of the Ca∗Cl/P ratio for primary hyperparathyroidism (PHPT), especially normocalcaemic PHPT (NPHPT), to assist health care providers in making reliable and rapid clinical identifications. METHODS From January 1, 2013, to March 31, 2023, 230 PHPT patients, including 65 with NPHPT and 230 sex- and age-matched controls, were enrolled in this retrospective study. Differences between hypercalcaemic PHPT (HPHPT) and NPHPT and between them and their respective controls were analyzed. The diagnostic accuracy of the Ca∗Cl/P ratio, Ca/P ratio, Cl/P ratio and albumin-corrected calcium was assessed by the area under the receiver operating characteristic curve. RESULTS Compared with corresponding controls, NPHPT and HPHPT patients both had significantly higher Ca ∗ Cl/P ratios (271.64 ± 51.74 vs 192.71 ± 26; 419.91 ± 139.11 vs 199.14 ± 36.75, P < .001). In the overall cohort, the ROC-AUC of the Ca∗Cl/P ratio (0.964, 95% CI = 0.943-0.979) for diagnosis of PHPT patients was superior to albumin-corrected calcium (0.959, 95% CI = 0.934-0.973), the Ca/P ratio (0.956, 95% CI = 0.934-0.973), and the Cl/P ratio (0.923, 95% CI = 0.895-0.946). A Ca ∗ Cl/P ratio above 239.17 mmol/L, with sensitivity (0.952), specificity (0.922), PPV (0.924), NPV (0.951) and accuracy (0.937), can distinguish PHPT patients from healthy individuals. Furthermore, the Ca ∗ Cl/P ratio yielded a sensitivity of 0.831, specificity of 0.938, PPV of 0.931, NPV of 0.847 and accuracy of 0.885 for NPHPT. CONCLUSION The Ca∗Cl/P ratio provides excellent diagnostic power for diagnosis of PHPT, especially NPHPT.

Abstract
OBJECTIVES The aims of this study were to develop and validate 2 simple scores for stratification of the risks of (1) any fragility (AF) and (2) major osteoporotic fracture (MOF) in type 2 diabetes (T2D) patients; we also compared the performance of these scores with that of the Fracture Risk Assessment Tool (FRAX) and its adjustments. DESIGN AND METHODS In this longitudinal cohort study, 1855 patients with T2D were enrolled from January 2015 to August 2019. Cox proportional hazard regression was used to model the 5-year risk of AF and MOF. These scores were internally validated using a bootstrap resampling method of 1000. RESULTS During a median follow-up of 5 years, 119 (6.42%) cases of AF and 92 (4.96%) cases of MOFs were identified. Both the concordance index (C-index) and calibration plots indicated improved identification performance using the newly established scores. Furthermore, these scores also showed improved outcomes regarding the decision curve analysis (DCA) and area under the curve (AUC) compared to the widely used FRAX and its derivatives. More importantly, these scores successfully separated T2D patients into risk groups according to significant differences in fracture incidence. CONCLUSIONS These novel scores enable simple and reliable fracture risk stratification in T2D patients. Future work is needed to validate these findings in external cohort(s).

Abstract
BACKGROUND This study aimed to compare the prevalence of sarcopenia according to the old and new Asian Working Group on Sarcopenia (AWGS) operational criteria and explore the effects of sarcopenia on adverse outcomes in older adults with type 2 diabetes (T2D). METHODS A total of 386 patients with T2D aged ≥ 60 years were recruited in retrospective cohort study. Sarcopenia was assessed with different versions of the AWGS consensus, including the AWGS2014, AWGS2019H (muscle mass adjusted for height), and AWGS2019B (muscle mass adjusted for body mass index). The median follow-up period was 47 months. The composite primary endpoint was the first occurrence of cardiovascular disease (CVD), fragility fracture, and all-cause mortality and the secondary outcomes included the three separate components of the primary outcome. RESULTS In this study, the prevalence of sarcopenia under different criteria was significantly different, with AWGS2019H having the highest prevalence of 31.3%. The agreement among sarcopenia criteria was unsatisfactory. By Cox regression analysis, all three AWGS definitions of sarcopenia were associated with the composite outcome of all-cause mortality, fracture and CVD (hazard ratio [HR], 2.69 vs. HR, 2.63; vs. HR, 2.23; model 3). Further exploratory analysis, sarcopenia defined by the AWGS2019H criteria was an independent risk factor for death, incident CVD, and fractures. While AWGS2014 criteria was an increased risk factor of death and CVD. The AWGS2019B criteria were only associated with incident fractures. CONCLUSION All three AWGS definitions of sarcopenia were associated the composite primary endpoint. Additionally, the AWGS2019H criteria may be a better independent risk factor for negative health outcomes.

Abstract
BACKGROUND AND AIMS The definition of and diagnostic criteria for sarcopenic obesity (SO) remain unclear, hindering the assessment of its prevalence as well as its clinical relevance to negative health outcomes, especially in diabetic patients, who are more prone to body composition changes. The aim of this study was to investigate the prevalence of SO and its impact on negative health outcomes among elderly patients with type 2 diabetes (T2DM) from the Ageing and Body Composition of Diabetes (ABCD) cohort. METHODS This retrospective cohort study included 386 elderly patients with T2DM (177 males and 209 females, mean age of 67.91 ± 6.10 years). SO was defined as the coexistence of sarcopenia defined by the 2019 Asian Working Group for Sarcopenia up-to-date consensus and obesity identified by five alternative measurements as follows: body mass index (BMI)≥28 kg/m2 (BMI28), BMI≥25 kg/m2 (BMI25), body fat percentage (BF%)≥25% for men or 35% for women, visceral fat area (VFA)≥100 cm2, or android fat mass (AF) higher than the sex-specific median. The primary endpoint was all-cause death or fragility fracture, and the secondary endpoint was a composite of cardiovascular diseases (CVDs). Cox proportional hazards regression analysis was used to estimate the association between SO and negative health outcomes. RESULTS The prevalence of SO was 0.2% (BMI28), 2.5% (BMI25), 9.8% (AF), and 18.7% (BF% or VFA) among elderly patients with T2DM, according to the different obesity surrogate markers. During a mean follow-up period of 3.46 ± 1.15 years, 50 patients reached the primary endpoint, and 33 patients had incident CVD. SO classified using BF% was significantly associated with the primary endpoint [hazard ratio (HR) = 2.94, 95% CI = 1.25-6.92] and incident CVD (HR = 6.02, 95% CI = 1.56-23.15), even after comprehensive adjustment for bone-, comorbidity-, and diabetes-specific confounding variables. When SO was classified using BMI25, VFA and AF, similar results were found for adverse outcomes. However, SO classified using BMI25 resulted in misclassification of SO for 61 participants, 19 of whom experienced adverse events during follow-up, and SO classified using VFA or AF was not significantly associated with incident CVD. CONCLUSIONS SO is not uncommon in geriatric patients with T2DM, and its prevalence varies widely depending on the diverse surrogate indices of body fat excess. Furthermore, SO may be a better independent risk factor for negative health outcomes when classified using BF%.

Abstract
The aim of this study was to describe the characteristics of diabetic foot ulcer (DFU) patients with anemia and assess the relationship between anemia and DFU outcome. A retrospective cohort study was conducted on patients with DFU who attended our hospital from May 2007 to September 2014. All of the variables in the DFU patients with and without anemia were compared. In this study, 353 subjects were included, anemia was present in 236 patients (66.9%). These patients were significantly male, more likely to be a smoker, had a lower level of serum albumin and worse kidney function, more likely to use at least 2 types of antibiotics and had a worse perfusion of the lower limb, a larger and deeper ulcer and a more severe infection. A multivariate analysis showed that male sex, lower serum albumin, and worse kidney function were independent predictors of anemia in DFU patients. Additionally, in multivariate models, anemia was one of the variables that was most significantly associated with adverse outcomes and with similar findings for secondary outcomes. Receiver operating characteristic analysis determined a hemoglobin cutoff of 12.3 g/dL (females) and 12.1 g/dL (males) to identify a high-risk population of DFU patients who would have adverse outcomes. So anemia is common in patients with DFU. Although typically mild or moderate, anemia has been associated with substantial morbidity and mortality in patients with DFU.

Abstract
Colony-stimulating factor 1 (CSF-1) regulates the survival, proliferation, and differentiation of mononuclear phagocytes. It is expressed as a secreted glycoprotein or proteoglycan found in the circulation or as a biologically active cell-surface glycoprotein. To investigate tissue CSF-1 regulation, CSF-1-null Csf1(op)/Csf1(op) mice expressing transgenes encoding the full-length membrane-spanning CSF-1 precursor driven by 3.13 kilobases of the mouse CSF-1 promoter and first intron were characterized. Transgene expression corrected the gross osteopetrotic, neurologic, weight, tooth, and reproductive defects of Csf1(op)/Csf1(op) mice. Detailed analysis of one transgenic line revealed that circulating CSF-1, tissue macrophage numbers, hematopoietic tissue cellularity, and hematopoietic parameters were normalized. Tissue CSF-1 levels were normal except for elevations in 4 secretory tissues. Skin fibroblasts from the transgenic mice secreted normal amounts of CSF-1 but also expressed some cell-surface CSF-1. Also, lacZ driven by the same promoter/first intron revealed beta-galactosidase expression in hematopoietic, reproductive, and other tissue locations proximal to CSF-1 cellular targets, consistent with local regulation by CSF-1 at these sites. These studies indicate that the 3.13-kilobase promoter/first intron confers essentially normal CSF-1 expression. They also pinpoint new cellular sites of CSF-1 expression, including ovarian granulosa cells, mammary ductal epithelium, testicular Leydig cells, serous acinar cells of salivary gland, Paneth cells of the small intestine, as well as local sites in several other tissues.
