Trajectory of adherence to home rehabilitation among older adults with hip fractures and cognitive impairment

This study aimed to identify different trajectories of adherence to home rehabilitation for older adults with hip fracture and cognitive impairment, to examine associations between different adherence trajectories and postoperative recovery outcomes, and to explore the predictors of adherence trajectories. Group-based trajectory modeling showed two adherence trajectories: low (39.06%) and high (60.94%) adherence. The high adherence group had better activities of daily living (β=11.77, p<.001), instrumental activities of daily living (β=0.56, p<.01), femoral muscular strength (β=3.35, p<.01) on the fractured side and quality of life (β=-0.81, p=.02) than the low adherence group. Participants who established exercise habits (OR=6.49, p<.01) and consulted a physical therapist (OR=4.29, p=.03) during hospitalization were more likely to be in the high adherence group.     

Bone Metabolism Discrepancy in Type 2 Diabetes Mellitus Patients With and Without Non-Alcoholic Fatty Liver Disease

To explore the distribution of several bone metabolic indicators in type 2 diabetes patients (T2DM) with and without non-alcoholic fatty liver disease (NAFLD) and to preliminarily evaluate the relationship of bone metabolism with NAFLD in patients with T2DM. The hospitalized patients with T2DM were divided into the group of T2DM complicated with NAFLD and the group of T2DM alone according to the results of ultrasonic diagnosis. The general information and laboratory test data such as bone metabolism indexes of these patients were collected and the differences of the indexes between the 2 groups were compared. Furthermore, the independent influencing factors of NAFLD in patients with T2DM were analyzed. A total of 186 patients were included in the study. Compared with patients with T2DM only, patients with T2DM combined with NAFLD were characterized with younger age (p < 0.001), higher BMI (p = 0.016), ALT (p = 0.001), TG (p = 0.005), HOMA-IR (p = 0.005), and lower HDL-C (p = 0.031). Significant discrepancy of age (OR 1.052, p = 0.001), ALT (OR 0.964, p = 0.047), HOMA-IR (OR 0.801, p = 0.005), and T-PINP (OR 1.022, p = 0.008) was found using multivariate logistic regression model. Significant discrepancy of T-PINP was found in T2DM patients with and without NAFLD. Further studies are needed to explore whether T-PINP could be used as a predictor of fatty liver disease, osteoporosis, and other related complications in patients with T2DM.     

Predictors of postoperative acute kidney injury in patients undergoing hip fracture surgery: A systematic review and meta-analysis

BackgroundThe present study aimed to summarize the predictors of acute kidney injury (AKI) in patients after hip surgery.MethodsA literature search was performed using PubMed, EMBASE, Cochrane Library, and Web of Science for studies assessing the predictors of AKI after hip fracture surgery. Pooled odds ratio (OR) and mean difference (MD) of those who experienced AKI compared to those who did not were calculated for each variable. Evidence was assessed using the Newcastle–Ottawa Scale.ResultsTen studies with 34 potential factors were included in the meta-analysis. In the primary analysis, 12 factors were associated with AKI, comprising males (OR 1.25; 95% confidence interval (CI) 1.14–1.36), advanced age (MD 2.28; 95% CI 0.80–3.75), myocardial infarction (OR 1.39; 95% CI 1.18–1.63), hypertension (OR 1.46; 95% CI 1.13–1.89), diabetes (OR 1.84; 95% CI 1.40–2.42), chronic kidney disease (OR 3.66; 95% CI 2.21–6.07), hip arthroplasty (OR 1.35; 95% CI 1.22–1.50), angiotensin-converting enzyme inhibitors/angiotensin receptor blockers use (OR 2.28; 95% CI 1.68–3.08), more intraoperative blood loss (MD 44.06; 95% CI 2.88–85.24), higher preoperative blood urea nitrogen levels (MD 5.29; 95% CI 3.38–7.20), higher preoperative serum creatinine levels (MD 0.4; 95% CI 0.26–0.53), and lower preoperative estimated glomerular filtration rate (MD −19.59; 95% CI −26.92–−12.26). Another 13 factors related to AKI in individual studies were identified in the systematic review.ConclusionRelated prophylaxis strategies should be implemented in patients involved with the above-mentioned characteristics to prevent AKI after hip surgery.     

经皮肾镜超声弹道碎石术治疗复杂性肾结石

目的：探讨经皮肾镜超声弹道碎石术治疗复杂性肾结石的疗效。方法：采用经皮肾镜联合EMS Ⅲ代超声弹道碎石清石系统治疗48例复杂性肾结石患者，完全性鹿角状结石12例，部分鹿角状结石30例，多发性结石6例。结石直径2．0～6．5cm，平均2．8cm。结果：48例患者中，43例Ⅰ期取净结石；5例完全性鹿角状结石者术后2个月仍有结石残留，结石直径均小于1．0cm，辅助施行ESWL后排净。结石粉碎率100％，结石清除率89．6％（43／48）。手术时间50～120min，平均70min，平均出血量50ml。无严重并发症发生。术后随访3～6个月，肾功能均有不同程度改善。结论：经皮肾镜下使用EMSⅢ代碎石清石系统治疗复杂性肾结石，具有高效、可靠、安全、损伤小、出血少及恢复快等优点，可以作为目前治疗复杂性肾结石的首选方法。     

RASSF1A基因表达对人肝癌细胞株QGY-7703生长的影响

目的观察RASSFlA基因的表达对人肝癌细胞株QGY-7703在体内外生长的影响。方法利用已构建成功的稳定表达RASSFlA基因的肝癌细胞株QGY-7703，通过细胞生长曲线、软琼脂集落形成试验、细胞周期的测定和裸鼠致瘤性试验对各稳定表达株的生物学行为进行检测。结果以未转染的QGY-7703为对照，RASSFlA基因的表达可明显抑制肝癌细胞在体外的生长速度，使肝癌细胞周期阻滞在G1／S期，显著降低肝癌细胞在软琼脂中形成的克隆数目（P〈0．01）和大小，显著减慢裸鼠皮下瘤的生长速度和重量（P〈0．01）。空载体的表达对肝癌细胞的生长影响不明显。结论RASSFlA的重表达抑制肝癌细胞在体内外的生长；RASSFlA基因是一个新的肝癌相关的抑癌基因。
