    质子泵抑制剂(PPI)用于胃食管反流病(GERD)的治疗包括一项短期试验,根据指导方针。在某些适应症下,长期使用是适当的。文献越来越多地记录了PPI的不利影响概况,包括肾脏疾病和骨骼脆弱。
    为了调查骨量减少的发生率,骨质疏松,和慢性肾脏病(CKD)患者使用PPI治疗超过8周的推荐试验期。
    单中心初级保健诊所的回顾性队列分析。包括年龄在18至65岁的PPI处方超过8周的患者。关于PPI处方的信息,人口统计,并收集了医学诊断。
    该搜索发现了293个PPI用户和1908个从未使用PPI的用户。人口统计各不相同,年龄的P值<0.05,体重指数(BMI),和黑人人口(PPI组较高)。PPI队列中骨质疏松症/骨质减少和CKD的发生率较高(P<0.001)。使用PPI诊断骨质疏松症/骨质减少的比值比(ORs)为2.91(95%CI=[1.692,4.979])。CKD和PPI使用的OR为1.14(95%CI=[1.141,2.229]),但与糖尿病相比更高,BMI升高,黑人种族,和男性性别。
    我们观察到骨质疏松症的发生率增加,或者骨质减少,长期使用PPI患者的CKD。人口统计学因年龄而异,BMI,和黑人种族比例。Logistic回归分析显示,PPI使用与肾脏疾病和骨质疏松症/骨质减少的可能性增加。这些结果增加了长期使用PPI和这些条件发展的证据,但需要更多的研究。
    UNASSIGNED: Proton-pump inhibitor (PPI) use for management of gastroesophageal reflux disease (GERD) consists of a short-duration trial, according to guidelines. Long-term usage is appropriate under certain indications. Literature has increasingly documented an adverse effect profile of PPIs, including kidney disease and bone fragility.
    UNASSIGNED: To investigate the rate of occurrence of osteopenia, osteoporosis, and chronic kidney disease (CKD) in patients using PPI therapy for longer than the recommended trial period of 8 weeks.
    UNASSIGNED: Retrospective cohort analysis of a single-site primary care clinic. Patients aged 18 to 65 years with PPI prescriptions longer than 8 weeks were included. Information regarding PPI prescriptions, demographics, and medical diagnoses was collected.
    UNASSIGNED: The search discovered 293 PPI-users and 1908 never-PPI-users. Demographics varied, with a P-value <0.05 in age, body mass index (BMI), and black population (higher in PPI group). The PPI cohort featured higher rates of osteoporosis/osteopenia and CKD (P < 0.001). The odds ratios (ORs) of diagnosis with PPI use was 2.91 (95% CI = [1.692, 4.979]) in osteoporosis/osteopenia. The OR was 1.14 (95% CI = [1.141, 2.229]) in CKD and PPI use but higher with diabetes, elevated BMI, black race, and male gender.
    UNASSIGNED: We observed increased occurrence rates of osteoporosis, or osteopenia, and CKD in patients with prolonged PPI use. Demographics varied in age, BMI, and black race proportion. A logistic regression revealed increased likelihood of kidney disease and osteoporosis/osteopenia in association with PPI use. These results add to the evidence regarding long-term PPI use and the development of these conditions, but additional studies are needed.

    骨质疏松症是一种炎症性疾病,在全球范围内造成巨大的疾病负担。膳食炎症指数(DII),反映饮食促炎/抗炎水平的综合评估指数与多种炎症性疾病有关.本研究旨在探讨DII与骨质疏松或骨量减少患者全因死亡率之间的关系。
    在这项回顾性队列研究中,我们从国家健康和营养检查调查(NHANES2007-2010,2013-2014,2017-2018)中提取了年龄≥45岁被诊断为骨量减少或骨质疏松症且具有完整饮食摄入信息的患者的数据.饮食摄入信息是从24小时饮食回忆访谈中获得的,并用于计算DII评分。加权单变量和多变量Cox比例风险模型用于探讨DII与骨质疏松或骨质减少患者全因死亡率之间的关系。风险比(HR)和95%置信区间(CIs)。基于不同年龄的亚组分析,进一步评估性别和并发症的相关性.
    共纳入5,381例患者。截至2019年12月31日,发生了1,286例全因死亡。调整所有协变量后,在骨质疏松或骨量减少患者中,高DII与全因死亡率相关(HR=1.28,95CI:1.10-1.48),尤其是男性(HR=1.38,95CI:1.06-1.78),年龄<65岁(HR=1.49,95CI:1.09-2.02),无心血管疾病病史(HR=1.30,95CI:1.03-1.65),糖尿病(HR=1.27,95CI:1.06-1.52)和慢性肾脏疾病(HR=1.28,95CI:1.03-1.58)。
    促炎饮食可能对骨质疏松症患者的预后产生不利影响。
    UNASSIGNED: Osteoporosis is an inflammatory disease that causes a large disease burden worldwide. Dietary inflammation index (DII), a comprehensive assessment index that reflects the pro-inflammatory/anti-inflammatory level of diet was related to multiple inflammatory diseases. This study aimed to explore the association between DII and all-cause mortality in patients with osteoporosis or osteopenia.
    UNASSIGNED: In this retrospective cohort study, data of patients aged ≥ 45 years diagnosed as osteopenia or osteoporosis and had complete dietary intake information were extracted from the National Health and Nutrition Examination Survey (NHANES 2007-2010, 2013-2014, 2017-2018). Dietary intake information was obtained from 24-h dietary recall interviews and was used to calculate the DII score. Weighted univariate and multivariate Cox proportional hazard models were utilized to explore the association between DII and all-cause mortality in patients with osteoporosis or osteopenia, with hazard ratios (HRs) and 95 % confidence intervals (CIs). Subgroup analyses based on different age, gender and complications were further assessed this association.
    UNASSIGNED: A total of 5,381 patients were included. Until December 31, 2019, 1,286 all-cause deaths occurred. After adjusting all covariates, high DII was associated with the high odds of all-cause mortality among patients with osteoporosis or osteopenia (HR=1.28, 95 %CI: 1.10-1.48), especially in the male (HR=1.38, 95 %CI: 1.06-1.78), aged < 65 years (HR=1.49, 95 %CI: 1.09-2.02), and without the history the cardiovascular disease (HR=1.30, 95 %CI: 1.03-1.65), diabetes mellitus (HR=1.27, 95 %CI: 1.06-1.52) and chronic kidney disease (HR=1.28, 95 %CI: 1.03-1.58).
    UNASSIGNED: A pro-inflammatory diet may have an adverse effect on the prognosis of osteoporosis patients.

    目的:我们的目的是预测约旦绝经后妇女中骨质减少和骨质疏松的患病率及其相关危险因素。
    方法:在这项横断面研究中,在2022年9月至2023年4月期间,共有368名绝经后妇女从约旦北部的阿卜杜拉国王大学医院(KAUH)招募.使用双能X射线吸收法扫描测量骨矿物质密度(BMD)。根据国际临床密度测定学会(ISCD)指南,使用T评分进行骨质疏松症诊断。有关社会人口统计学和生活方式变量的数据是通过面对面访谈收集的。使用医疗记录来检索参与者的BMD信息。使用逻辑回归确定骨质疏松症的预测因子。
    结果:骨质疏松患病率为40.5%,而44.6%的参与者被诊断为骨量减少。腰椎骨质疏松发生率最高(30.4%),而左侧股骨颈骨量减少的患病率最高(46.3%)。绝经后妇女的年龄(p值=.024),和慢性病史(p值=0.038)是与骨质疏松症风险增加相关的显著因素。
    结论:来自约旦的绝经后妇女骨质疏松症和骨量减少的患病率较高。因此,有必要针对导致骨质疏松症的危险因素,并通过患者教育改善患者的生活方式。医疗保健系统应考虑在绝经年龄及其后早期筛查骨质疏松症的方法。根据该年龄组的血清水平,可以常规考虑补充钙和维生素D。
    OBJECTIVE: Our aim was to predict the prevalence of osteopenia and osteoporosis and their associated risk factors among postmenopausal women from Jordan.
    METHODS: In this cross-sectional study, a total of 368 postmenopausal women were recruited from King Abdullah University Hospital (KAUH) in the North of Jordan between September 2022 and April 2023. Bone mineral density (BMD) was measured using a dual-energy X-ray absorptiometry scan. T-score was used for osteoporosis diagnosis in accordance with the International Society for Clinical Densitometry (ISCD) guidelines. Data about sociodemographic and lifestyle variables were collected using face-to-face interviews. Medical records were used to retrieve participants\' BMD information. Predictors of osteoporosis were identified using logistic regression.
    RESULTS: Prevalence of osteoporosis was 40.5%, while 44.6% of participants were diagnosed with osteopenia. The lumbar spine had the highest frequency of osteoporosis (30.4%), while the left femoral neck had the highest prevalence of osteopenia (46.3%). Postmenopausal women\'s age (p-value = .024), and history of chronic diseases (p-value = .038) were significant factors associated with increased osteoporosis risk.
    CONCLUSIONS: Postmenopausal women from Jordan had high prevalence of osteoporosis and osteopenia. It is therefore necessary to target risk factors leading to osteoporosis and to improve patients\' lifestyles through patient education. Healthcare systems should consider early screening approaches for osteoporosis at the age of menopause and thereafter. Supplements of calcium and vitamin D may be routinely considered for this age group depending on their serum levels.

    医学领域的多项研究强调了使用卷积神经网络预测医疗状况的显着有效性,有时甚至超过医疗专业人员。尽管他们表现出色,卷积神经网络作为黑匣子运行,可能由于不正确的原因或重点领域而得出正确的结论。我们的工作探索了通过识别和遮挡图像中的混杂变量来减轻这种现象的可能性。具体来说,我们专注于骨质减少的预测,严重的医疗状况,使用公开可用的GRAZPEDWRI-DX数据集。在检测到数据集中的混杂变量后,我们生成遮罩,遮挡与这些变量相关的图像区域。通过这样做,模型被迫专注于图像的不同部分进行分类。使用F1分数进行模型评估,精度,和回忆表明,在非遮挡图像上训练的模型通常优于在遮挡图像上训练的模型。然而,一项放射科医师必须根据GRAD-CAM方法提取的聚焦区域选择模型的测试显示了不同的结果.放射科医生的偏好转向在遮挡图像上训练的模型。这些结果表明,虽然遮挡混杂变量可能会降低模型性能,它增强了可解释性,为预测背后的推理提供更可靠的见解。重复我们的实验的代码可以在以下链接中找到:https://github.com/mikulicmateo/osteopenia。
    Multiple studies within the medical field have highlighted the remarkable effectiveness of using convolutional neural networks for predicting medical conditions, sometimes even surpassing that of medical professionals. Despite their great performance, convolutional neural networks operate as black boxes, potentially arriving at correct conclusions for incorrect reasons or areas of focus. Our work explores the possibility of mitigating this phenomenon by identifying and occluding confounding variables within images. Specifically, we focused on the prediction of osteopenia, a serious medical condition, using the publicly available GRAZPEDWRI-DX dataset. After detection of the confounding variables in the dataset, we generated masks that occlude regions of images associated with those variables. By doing so, models were forced to focus on different parts of the images for classification. Model evaluation using F1-score, precision, and recall showed that models trained on non-occluded images typically outperformed models trained on occluded images. However, a test where radiologists had to choose a model based on the focused regions extracted by the GRAD-CAM method showcased different outcomes. The radiologists\' preference shifted towards models trained on the occluded images. These results suggest that while occluding confounding variables may degrade model performance, it enhances interpretability, providing more reliable insights into the reasoning behind predictions. The code to repeat our experiment is available on the following link: https://github.com/mikulicmateo/osteopenia .

    这项研究调查了中国HIV感染者(PLWH)的低骨密度(BMD)患病率和相关因素。在老年人中发现持续的高BMD风险,即使在调整了年龄和体重指数(BMI)之后。值得注意的是,洛匹那韦/利托那韦(LPV/r)治疗与降低BMD有关,强调在较旧的PLWH中迫切需要定期进行BMD监测和干预。
    目的:HIV感染和抗逆转录病毒治疗(ART)已被证明有助于降低BMD,导致骨质减少和骨质疏松症的易感性增加。然而,关于中国PLWH中降低BMD的患病率及其相关因素的知识有限。在这项横断面研究中,我们旨在调查中国PLWH中低BMD的患病率和相关因素。
    方法:我们回顾性招募了PLWH和非HIV志愿者,他们接受了双能X线骨密度仪(DXA)扫描以测量骨密度。人口统计信息,实验室测试结果,ART方案,收集治疗持续时间。进行单因素和多元回归分析以确定影响PLWH中异常骨量的因素。
    结果:本研究共纳入829人,包括HIV组(n=706)和非HIV组(n=123)。在所有PLWH中,低BMD的患病率为13.88%(706个中的98个)。然而,在50岁及以上的PLWH中,患病率上升至65.32%(124人中有81人).相比之下,同一年龄组的对照组的患病率为38.21%(123人中有47人).在调整了年龄和BMI后,与非HIV组相比,年龄较大的PLWH仍然表现出更高的低BMD患病率(68.24%vs34.94%,P<0.001)。多变量分析显示,年龄与PLWH中的低BMD风险较高密切相关。在未接受ART治疗的人群中,年龄每增加10年,比值比(OR)为6.28(95%置信区间[CI],3.12-12.65;P<0.001),在有ART经验的人群中OR为4.83(3.20-7.29,P<0.001)。在有ART经验的小组中,目前LPV/r治疗与低BMD风险增加相关(OR=3.55,1.24-10.14,P<0.05),随着BMI的降低(OR=0.84,0.75-0.95,P<0.05),碱性磷酸酶升高(OR=1.02,1.01-1.03,P<0.01)。
    结论:50岁及以上的PLWH患者的低BMD患病率高于非HIV患者。在ART中使用LPV/r与降低的BMD相关。这些发现强调了在老年PLWH中定期监测BMD的重要性,以及需要适当的干预措施来减轻该人群中骨量减少和骨质疏松症的风险。
    This study examined low bone mineral density (BMD) prevalence and associated factors among Chinese people living with HIV (PLWH), uncovering a persistent high BMD risk in older individuals, even after adjusting for age and body mass index (BMI). Notably, lopinavir/ritonavir (LPV/r) therapy was linked to reduced BMD, highlighting the imperative need for regular BMD monitoring and interventions in older PLWH.
    OBJECTIVE: HIV infection and antiretroviral therapy (ART) have been shown to contribute to lower BMD, resulting in an increased susceptibility to osteopenia and osteoporosis. However, there is limited knowledge about the prevalence of reduced BMD and its associated factors among Chinese PLWH. In this cross-sectional study, we aimed to investigate the prevalence and factors associated with low BMD among PLWH in China.
    METHODS: We retrospectively enrolled PLWH and non-HIV volunteers who underwent dual-energy X-ray absorptiometry (DXA) scans to measure bone density. Demographic information, laboratory test results, ART regimens, and treatment duration were collected. Univariate and multiple regression analyses were performed to identify factors influencing abnormal bone mass in PLWH.
    RESULTS: A total of 829 individuals were included in this study, comprising the HIV group (n = 706) and the non-HIV group (n = 123). The prevalence of low BMD among all PLWH was found to be 13.88% (98 out of 706). However, among PLWH aged 50 years and above, the prevalence increased to 65.32% (81 out of 124). In contrast, control subjects in the same age group had a prevalence of 38.21% (47 out of 123). After adjusting for age and BMI, older PLWH still demonstrated a higher prevalence of low BMD compared to the non-HIV group (68.24% vs 34.94%, P < 0.001). Multivariate analysis revealed that older age was strongly associated with a higher risk of low BMD among PLWH, with an odds ratio (OR) of 6.28 for every 10-year increase in age in the ART-naïve population (95% confidence intervals [CIs], 3.12-12.65; P < 0.001) and OR of 4.83 in the ART-experienced population (3.20-7.29, P < 0.001). Within the ART-experienced group, current LPV/r treatment was associated with an increased risk of low BMD (OR = 3.55, 1.24-10.14, P < 0.05), along with lower BMI (OR = 0.84, 0.75-0.95, P < 0.05), and elevated alkaline phosphatase (OR = 1.02, 1.01-1.03, P < 0.01).
    CONCLUSIONS: The prevalence of low BMD is higher among PLWH aged 50 years and above compared to non-HIV individuals. The use of LPV/r for ART is associated with reduced BMD. These findings emphasize the importance of regular monitoring of BMD in older PLWH and the need for appropriate interventions to mitigate the risks of osteopenia and osteoporosis in this population.

    雷洛昔芬可增加骨质疏松症患者的腰椎骨密度(BMD)并降低椎骨骨折风险。然而,很少有前瞻性临床试验研究其对绝经后骨质减少妇女的疗效。这项研究调查了雷洛昔芬在绝经后骨量减少妇女中的疗效。一个调查员发起的,随机化,开放标签,prospective,在112例骨量减少的绝经后女性中进行了单中心试验.根据腰椎的最低BMDT评分定义骨质减少,股骨颈,或全髋关节(-2.5<最低T评分<-1.0)。参与者被随机分配接受雷洛昔芬60mg/天加胆钙化醇800IU/天(RalD)或胆钙化醇800IU/天(VitD),共48周。在基线,两组的平均年龄(63.1±6.8岁)无差异.然而,在RalD组,平均体重指数(BMI)和基线T评分较低,而25-羟维生素D水平较高。在48周,RalD组腰椎BMD增加更大(RalDvs.VitD;2.6%vs.-0.6%,P=.005),并减轻总髋部BMD损失(-0.3%vs.-2.9%,P=.003)。调整年龄后,雷洛昔芬对腰椎的影响仍然显着,BMI,基线BMDT评分,和其他协变量(调整后的β:+3.05与VitD,P=.015)。在亚组分析中,RalD组和VitD组的腰椎BMD在严重骨量减少组中差异显著(最低T评分≤-2.0).与单用胆钙化醇相比,雷洛昔芬加胆钙化醇可显著改善腰椎BMD并减轻全髋关节BMD损失。在严重骨质减少中具有更强大的作用。临床试验注册:该试验已在ClinicalTrials.gov(NCT05386784)注册。
    Raloxifene increases lumbar spine bone mineral density (BMD) and lowers vertebral fracture risk in patients with osteoporosis. However, few prospective clinical trials have studied its efficacy in postmenopausal women with osteopenia. This study investigated the efficacy of raloxifene in postmenopausal women with osteopenia. An investigator-initiated, randomized, open-label, prospective, single-center trial was conducted in 112 postmenopausal women with osteopenia. Osteopenia was defined based on the lowest BMD T-score in the lumbar spine, femoral neck, or total hip (-2.5 < lowest T-score < -1.0). Participants were randomly assigned to receive raloxifene 60 mg/day plus cholecalciferol 800 IU/day (RalD) or cholecalciferol 800 IU/day (VitD) for 48 wk. At baseline, mean age (63.1 ± 6.8 yr) did not differ between the two groups. However, in the RalD group, mean body mass index (BMI) and baseline T-score were lower, while 25-hydroxyvitamin D level was higher. At 48 wk, the RalD group showed a greater increase in lumbar spine BMD (RalD vs. VitD; 2.6% vs. -0.6%, P =.005) and attenuated the total hip BMD loss (-0.3% vs. -2.9%, P = .003). The effect of raloxifene on the lumbar spine remained significant after adjustment for age, BMI, baseline BMD T-score, and other covariates (adjusted β: +3.05 vs. VitD, P =.015). In subgroup analysis, the difference in lumbar spine BMD between the RalD and VitD groups was robust in those with severe osteopenia group (lowest T-score ≤ -2.0). Raloxifene plus cholecalciferol significantly improved lumbar spine BMD and attenuated total hip BMD loss compared with cholecalciferol alone, with a more robust effect in severe osteopenia. Clinical trial registration: The trial was registered with ClinicalTrials.gov (NCT05386784).

    素食主义的日益流行决定了需要全面研究这些饮食对健康,特别是骨骼代谢的影响。我们假设素食主义者之间的饮食差异很大,乳卵素食者,杂食动物也会导致其营养状况的显着差异,这可能会影响骨骼健康。
    该研究评估了腰椎和股骨颈的双能X射线吸收测量参数,平均营养素摄入量,血清营养素浓度,血清PTH水平,46名素食者的尿液pH值,38名乳卵素食者,和44个杂食动物。
    两组之间的骨矿物质密度(BMD)没有差异。然而,与杂食动物相比,纯素食者的甲状旁腺激素(PTH)水平仍然更高,尽管所有组甲状旁腺功能亢进的患病率相同。这些发现可能是因为每个小组都有自己的“优势和劣势”。\"因此,素食主义者和,在较小程度上,乳卵素食者消耗更多的钾,镁,铜,锰,和维生素B6,B9和C。杂食动物的饮食含有更多的蛋白质和维生素D和B12。所有受试者消耗的维生素D比推荐的少。超过一半的素食主义者和杂食动物血液中维生素D不足甚至缺乏。锰的低血清浓度及其足够的摄入量也值得注意:在57%的素食主义者中观察到锰的缺乏,79%的乳卵素食者,和63%的杂食动物。
    目前,不再可能得出乳卵素食者的BMD低于杂食动物的结论,我们的研究支持。我们研究中的素食者也没有表现出较低的BMD值,只有更高的PTH血液浓度,与杂食动物相比,然而,大量的研究,包括最近,显示相反的观点。在这方面,需要进一步的大规模研究。素食主义者和乳卵素食者现在有各种富含维生素D和B12以及钙的食物。道德来源的膳食补充剂也有很大的多样性。发现的低浓度锰需要进一步研究。
    UNASSIGNED: The growing prevalence of vegetarianism determines the need for comprehensive study of the impact of these diets on health and particularly on bone metabolism. We hypothesized that significant dietary differences between vegans, lacto-ovo-vegetarians, and omnivores also cause significant differences in their nutrient status, which may affect bone health.
    UNASSIGNED: The study assessed dual-energy X-ray absorptiometry parameters in lumbar spine and femoral neck, average nutrient intake, serum nutrient concentrations, serum PTH levels, and urinary pH among 46 vegans, 38 lacto-ovo-vegetarians, and 44 omnivores.
    UNASSIGNED: There were no differences in bone mineral density (BMD) between the groups. However, the parathyroid hormone (PTH) levels were still higher in vegans compared to omnivores, despite the same prevalence of hyperparathyroidism in all groups. These findings may probably be explained by the fact that each group had its own \"strengths and weaknesses.\" Thus, vegans and, to a lesser extent, lacto-ovo-vegetarians consumed much more potassium, magnesium, copper, manganese, and vitamins B6, B9, and C. At the same time, the diet of omnivores contained more protein and vitamins D and B12. All the subjects consumed less vitamin D than recommended. More than half of vegans and omnivores had insufficiency or even deficiency of vitamin D in the blood. Low serum concentrations of manganese with its quite adequate intake are also noteworthy: its deficiency was observed in 57% of vegans, 79% of lacto-ovo-vegetarians, and 63% of omnivores.
    UNASSIGNED: Currently, it is no longer possible to conclude that lacto-ovo-vegetarians have lower BMD than omnivores, as our research supported. Vegans in our study also did not demonstrate lower BMD values, only higher PTH blood concentrations, compared to omnivores, however, a large number of studies, including recent, show the opposite view. In this regard, further large-scale research is required. Vegans and lacto-ovo-vegetarians now have a variety of foods fortified with vitamins D and B12, as well as calcium. There is also a great diversity of ethically sourced dietary supplements. The found low concentrations of manganese require further investigation.

    背景:血清尿酸与骨质疏松或骨量减少之间的关系仍存在争议,很少有研究探讨BMI是否在SUA和OP/骨量减少之间起中介作用。
    目的:探讨美国成年人血清尿酸与骨质疏松或骨质减少的关系。
    方法:进行了一项横断面研究,以检查来自NHANES四个周期的血清尿酸与骨质疏松症或骨量减少之间的关系。采用二元logistic回归模型和限制性三次样条模型评价血尿酸与骨质疏松或骨质减少的关系,并使用交互分析来检验亚组之间的差异。中介分析用于调查BMI是否在SUA和OP/骨质减少之间的关联中起中介作用。
    结果:纳入12581名年龄≥18岁的参与者。在所有人群中,SUA与骨质疏松症或骨质减少之间存在U形非线性关系(P<0.0001,P=0.0287)。年龄亚组存在显著的交互作用(交互作用的P=0.044),性别亚组(相互作用的P=0.005),和BMI亚组(相互作用的P=0.017)。我们进一步评估了亚组,发现男性骨质疏松症或骨质减少风险较低的血清尿酸水平的最佳范围为357-535µmol/L,年龄≥50岁的人327-417µmol/L,年龄<50岁的人超过309μmol/L,BMI≥30的人群为344-445µmol/L,BMI<30的人群为308µmol/L以上。BMI完全介导SUA与OP/骨质减少的关联,值为-0.0024(-0.0026--0.0021)。这些结果在敏感性分析中是稳健的。
    结论:在不同人群中观察到SUA与骨骼健康之间的复杂关系。将SUA维持在特定范围内可能有益于骨骼健康。此外,BMI可能在SUA与骨骼健康之间的关联中起重要作用,但是考虑到这项研究的局限性,需要进一步的前瞻性研究。
    BACKGROUND: The associations between serum uric acid and osteoporosis or osteopenia remain controversial, and few studies have explored whether BMI acts as a mediators in the association between the SUA and OP/ osteopenia.
    OBJECTIVE: To explore the relationship between serum uric acid and osteoporosis or osteopenia among US adults.
    METHODS: A cross-sectional study was conducted to examine the association between serum uric acid and osteoporosis or osteopenia from four cycles of NHANES. Binary logistic regression models and restricted cubic spline models were used to evaluate the association between serum uric acid and osteoporosis or osteopenia, and interaction analysis was used to test the differences between subgroups. Mediation analysis was utilized to investigate whether BMI acts as a mediator in the association between SUA and OP/ osteopenia.
    RESULTS: 12581 participants aged ≥ 18 years were included. A U-shape nonlinear relationship between SUA and osteoporosis or osteopenia in all people was found (P < 0.0001, P for nonlinear = 0.0287). There were significant interactions in age subgroups (P for interaction = 0.044), sex subgroups (P for interaction = 0.005), and BMI subgroups (P for interaction = 0.017). We further assessed the subgroups and found the optimal range of serum uric acid levels with a lower risk of osteoporosis or osteopenia was 357-535 µmol/L in males, 327-417 µmol/L in people aged ≥ 50 years, above 309 µmol/L in people aged < 50 years, 344-445 µmol/L in people with BMI ≥ 30, and above 308 µmol/L in people with BMI < 30. BMI fully mediated the association of SUA and OP/osteopenia, with a value of -0.0024(-0.0026--0.0021). These results were robust in sensitivity analyses.
    CONCLUSIONS: A complicated relationship between SUA and bone health in different populations was observed. Maintaining SUA within a specific range may be beneficial to bone health. In addition, BMI may play an important role in the association between SUA and bone health, but considering the limitations of this study, further prospective research is required.

    背景:骨质减少,由绝经后妇女雌激素缺乏(PMW)引起,降低骨矿物质密度(BMD)并增加骨骼脆性。它影响了大约一半的老年妇女的社会和身体健康。PMW经历疼痛和残疾,影响他们健康相关的生活质量(QoL)和功能。这项研究旨在确定基于Kinect的虚拟现实训练(VRT)对骨量减少的PMW的物理性能和QoL的影响。
    方法:这项研究是一项前瞻性的,双臂,并行设计,随机对照试验。该试验招募了52名参与者,每组随机分配26个。实验组接受基于Kinect的VRT,每周三次,持续24周,每次持续45分钟。两组都被指示每天在外面进行30分钟的步行。物理性能通过计时测试(TUG)测量,功能到达测试(FRT),五次坐立测试(FTSST),改进的坐姿和到达测试(MSRT),动态握力(DHGS),非动态握力(NDHGS),BORG评分和呼吸困难指数。EscaladeCalidaddevida骨质疏松症(ECOS-16)问卷测量了QoL。在基线时评估身体表现和生活质量指标,12周后,24周后。数据在SPSS25上进行分析。
    结果:PMW参与者的平均年龄为58.00±5.52岁。在组内比较中,所有结果变量(TUG,FRT,FTSST,MSRT,DHGS,NDHGS,BORG得分,呼吸困难,和ECOS-16)在实验组的第12周和第24周以及基线和第24周之间均显示出从基线的显着改善(p<0.001)。在对照组中,除FRT(第12周至第24周)外,所有结局变量在第12周和第24周以及基线与第24周之间均显示较基线有统计学意义的改善(p<0.001).在组间比较中,实验组在所有时间点的大多数结果变量都比对照组显着改善(p<0.001),表明基于Kinect的VRT的积极附加效果。
    结论:该研究得出的结论是,实验组和对照组的身体表现和QoL指标都得到了改善。然而,在群体比较中,这些变量在实验组中显示出更好的结果。因此,基于Kinect的VRT是一种替代且可行的干预措施,可改善骨质减少的PMW的身体表现和QoL。这种新颖的方法可能广泛适用于即将进行的研究,考虑到人们对基于虚拟现实的康复治疗的兴趣日益增加。
    BACKGROUND: Osteopenia, caused by estrogen deficiency in postmenopausal women (PMW), lowers Bone Mineral Density (BMD) and increases bone fragility. It affects about half of older women\'s social and physical health. PMW experience pain and disability, impacting their health-related Quality of Life (QoL) and function. This study aimed to determine the effects of Kinect-based Virtual Reality Training (VRT) on physical performance and QoL in PMW with osteopenia.
    METHODS: The study was a prospective, two-arm, parallel-design, randomized controlled trial. Fifty-two participants were recruited in the trial, with 26 randomly assigned to each group. The experimental group received Kinect-based VRT thrice a week for 24 weeks, each lasting 45 min. Both groups were directed to participate in a 30-min walk outside every day. Physical performance was measured by the Time Up and Go Test (TUG), Functional Reach Test (FRT), Five Times Sit to Stand Test (FTSST), Modified Sit and Reach Test (MSRT), Dynamic Hand Grip Strength (DHGS), Non-Dynamic Hand Grip Strength (NDHGS), BORG Score and Dyspnea Index. Escala de Calidad de vida Osteoporosis (ECOS-16) questionnaire measured QoL. Both physical performance and QoL measures were assessed at baseline, after 12 weeks, and after 24 weeks. Data were analyzed on SPSS 25.
    RESULTS: The mean age of the PMW participants was 58.00 ± 5.52 years. In within-group comparison, all outcome variables (TUG, FRT, FTSST, MSRT, DHGS, NDHGS, BORG Score, Dyspnea, and ECOS-16) showed significant improvements (p < 0.001) from baseline at both the 12th and 24th weeks and between baseline and the 24th week in the experimental group. In the control group, all outcome variables except FRT (12th week to 24th week) showed statistically significant improvements (p < 0.001) from baseline at both the 12th and 24th weeks and between baseline and the 24th week. In between-group comparison, the experimental group demonstrated more significant improvements in most outcome variables at all points than the control group (p < 0.001), indicating the positive additional effects of Kinect-based VRT.
    CONCLUSIONS: The study concludes that physical performance and QoL measures were improved in both the experimental and control groups. However, in the group comparison, these variables showed better results in the experimental group. Thus, Kinect-based VRT is an alternative and feasible intervention to improve physical performance and QoL in PMW with osteopenia. This novel approach may be widely applicable in upcoming studies, considering the increasing interest in virtual reality-based therapy for rehabilitation.

    衰老伴随着肌肉和骨骼质量的损失,导致一种称为骨减少症的疾病。循环,细胞,和组织生物标志物的研究是比较缺乏的,目前,没有确定的生物标志物存在。在这里,我们发现骨肉瘤患者表现出升高的嗜碱性粒细胞和TNFα水平,随着PPT的减少,PT/INR,IL15Alpha-Klotho,DHEA-S,和FGF-2表达以及独特的骨和肌肉组织微结构和生物标志物表达。它们还显示破骨细胞前体的增加,伴随着自发破骨细胞生成的失衡。注意到骨质减少和肌肉减少患者的相似性,包括较低的中性粒细胞百分比和改变的细胞因子表达。基于所选生物标志物的模型的线性判别分析(LDA)显示在61-78%范围内的分类准确度。总的来说,我们的数据为新的骨量减少症生物标志物提供了令人信服的证据,这些生物标志物可能作为促进健康衰老的诊断工具.
    Aging comes with the loss of muscle and bone mass, leading to a condition known as osteosarcopenia. Circulating, cellular, and tissue biomarkers research for osteosarcopenia is relatively scarce and, currently, no established biomarkers exist. Here we find that osteosarcopenic patients exhibited elevated basophils and TNFα levels, along with decreased aPPT, PT/INR, IL15, alpha-Klotho, DHEA-S, and FGF-2 expression and distinctive bone and muscle tissue micro-architecture and biomarker expressions. They also displayed an increase in osteoclast precursors with a concomitant imbalance towards spontaneous osteoclastogenesis. Similarities were noted with osteopenic and sarcopenic patients, including a lower neutrophil percentage and altered cytokine expression. A linear discriminant analysis (LDA) on models based on selected biomarkers showed a classification accuracy in the range of 61-78%. Collectively, our data provide compelling evidence for novel biomarkers for osteosarcopenia that may hold potential as diagnostic tools to promote healthy aging.
