Analysis of the predictive value of the Geriatric Nutritional Risk Index for osteoporosis in elderly patients with T2DM: a single-center retrospective study.

BACKGROUND: Malnutrition is recognized as a risk factor for osteoporosis and T2DM. Previous studies have demonstrated the relationship between nutritional assessment tools and BMD. However, few studies have compared the effects of three nutritional risk assessment tools (GNRI, CONUT, and PNI). This study aimed to investigate the correlation between three nutritional assessment tools and BMD and to compare their validity in predicting osteoporosis in type 2 diabetes mellitus in the elderly. METHODS: This retrospective study collected clinical data from 525 elderly patients with type 2 diabetes mellitus and categorized the patients into osteoporotic and non-osteoporotic groups. The correlation between the three nutritional assessment tools and BMD was analyzed using Spearman partial correlation. Binary logistics regression was used to analyze the relationship between GNRI and osteoporosis. ROC curves were used to compare the validity of GNRI, PNI, and CONUT in predicting osteoporosis. RESULTS: Spearman's partial correlation showed a positive correlation between femoral neck BMD and lumbar spine BMD, but no correlation was observed between total hip BMD and GNRI. Logistic regression analyses showed no association between PNI, CONUT scores, and the development of osteoporosis. After adjusting for age, sex, smoking, alcohol consumption, BMI, ALB, Cr, UA, FBG, TG, and HDL, the correlation between GNRI and osteoporosis remained. ROC curve analysis showed that GNRI in combination with age and albumin had better predictive ability for osteoporosis than PNI and CONUT. CONCLUSION: GNRI was an independent protective factor against osteoporosis in elderly patients with T2DM, and the predictive ability of GNRI for osteoporosis in elderly patients with T2DM was better than that of PNI and CONUT scores.

Efficacy of Hemiarthroplasty vs. Locking Plate Fixation for Proximal Humerus Fractures: A Meta-Analysis.

Background: Proximal humerus fractures are common in a clinic and account for ~6% of all adult fractures. Hemiarthroplasty (HA) or locking plate (LP) fixation is currently recommended for the treatment of complex proximal humerus fractures (PHFs); however, there is no uniform standard for optimal surgical treatment or functional recovery. We conducted a meta-analysis to compare the efficacy of LP and HA in the treatment of PHFs. Methods: Relative studies associated with HA and LP were searched in December 2020 in the PubMed, Embase, Cochrane Library, and OVID databases. The quality of the studies, functional outcomes (including the Constant-Murley score (CMS), American Shoulder and Elbow Surgeons Score (ASES), Simple Shoulder Test (SST), Short Form Health Survey (SF-12v2), complications, and reoperation rate were extracted and analyzed with the Stata 14.0 software. Results: A total of 958 patients from 12 studies were included in the meta-analysis, which showed that patients treated with LP had a significantly lower reoperation rate, a higher complication rate, and a higher CMS score than those treated with HA. There were no significant differences in ASES, SST, or SF-12v2 scores between treatment groups. Conclusions: Compared with HA, LP exhibited better clinical efficacy in some aspects. However, large sample and randomized, controlled studies are needed for further validation.

Effect of early restrictive fluid resuscitation on inflammatory and immune factors in patients with severe pelvic fracture.

PURPOSE: To study the effect of early restrictive fluid resuscitation (EFR) on inflammatory and immune factors in patients with severe pelvic fracture (SPF). METHODS: A total of 174 SPF patients in the Department of Orthopaedics, the First Affiliated Hospital of Chengdu Medical College from July 2015 to June 2018 were involved in this study and divided into EFR group (n = 87) and control group (n = 87) using the random number table method. Conventional fluid resuscitation (CFR) was performed in control group, and EFR was performed in EFR group. The incidences of acute respiratory distress syndrome (ARDS) and multiple organ dysfunction syndrome (MODS) during rescue, successful rescue rate, blood transfusion volume, fluid input, and resuscitation time were compared between the two groups. The parameters including prothrombin time (PT), hematocrit (HCT), platelet (PLT) and blood lactate (BL) at the 4th hour after fluid resuscitation were recorded. The levels of inflammatory factors (TNF-α, IL-6, CRP) and immune factors (CD3+, CD4+, CD8+, CD4+/CD8+) were compared between the two groups before treatment and 7 days after treatment. The revised acute physiologic and chronic health evaluation system and the sequential organ failure assessment scores were adopted for evaluation before treatment and 7 days after treatment. RESULTS: The incidences of ARDS and MODS during rescue in EFR group were significantly lower than those in control group (p=0.015 and 0.010 respectively), and the successful rescue rate in EFR group was significantly higher than that in control group (p = 0.011). The blood transfusion volume, fluid input, resuscitation time in EFR group were significantly lower than those in control group (p = 0.016, 0.002 and 0.001 respectively). At the 4th hour after fluid resuscitation, PT and BL in EFR group were significantly lower than those in control group (p = 0.021 and 0.003 respectively), while HCT and PLT in EFR group were significantly higher than those in control group (p = 0.016 and 0.021 respectively). On day 7 after treatment, TNF-α, IL-6, CRP and CD8+ in EFR group were significantly lower than those in control group (p = 0.003, 0.004, 0.007 and 0.003 respectively), while CD3+, CD4+ and CD4+/CD8+ in EFR group were significantly higher than those in control group (p = 0.004, 0.000, 0.007 respectively). On day 7 after treatment, the revised acute physiologic and chronic health evaluation (APACHE) system and the sequential organ failure assessment (SOFA) scores in EFR group were significantly lower than those in control group. CONCLUSION: EFR can effectively eliminate inflammatory factors, improve immune function, maintain the stability of blood components, reduce the incidences of ARDS and MODS, and elevate the successful rescue rate in patients with SPF.

Determinants for low bone mineral density in pre-school children: a matched case-control study in Wuhan, China.

Introduction Reduced bone mass will increase bone fragility and risk of fractures. Thus, it is better to note its determinants as early as possible. Objective This study aimed to find and determine the determinants for low bone mineral density (BMD) in pre-school children. Methods Between November 2014 and April 2015, a matched case-control study was performed to detect information on growth and development condition and consumption frequency of products of cases with low BMD and controls with normal BMD. Anthropometric data measurement and blood tests were conducted. Besides, the questionnaires concerning the mentioned information were completed to get relevant determinants. A paired t-test, the McNemar test and univariate and multiple conditional logistic regression models were used to explore the association between these factors and low BMD. Results In total, 88 (28 boys, 60 girls) incident cases (4.15 ± 0.78 years) of low BMD and 88 sex- and age-matched (±2 months) controls (4.16 ± 0.80 years) of normal BMD were enrolled. The results of multiple conditional logistic regression analysis indicated that if children had larger chest circumference (odds ratio [OR] = 0.763), longer duration of breastfeeding (OR = 0.899) and lower frequency of eating snacks (OR = 0.439), the risk of low BMD would decrease. Conclusions Our findings suggest that pre-school children with an association of larger chest circumference, longer duration of breastfeeding and lower frequency of eating snacks could have lower risk for low BMD. Intended measures to strengthen those protective factors could be effective in reducing the cases of low BMD.

Comorbid generalized anxiety disorder and its association with quality of life in patients with major depressive disorder.

The comorbidity of major depressive disorder (MDD) and generalized anxiety disorder (GAD) is common and often predicts poorer outcomes than either disorder alone. This study aimed to examine the prevalence of comorbid GAD and its association with quality of life (QOL) among MDD patients. A total of 1225 psychiatric outpatients were screened using the Hospital Anxiety and Depression Scale (HADS). Those who scored ≥8 on the HADS were interviewed using DSM-IV criteria by two senior psychiatrists. Patients diagnosed with MDD were further assessed using the 9-item Patient Health Questionnaire, Social Support Rating Scale, Pittsburgh Sleep Quality Index, and World Health Organization QOL Scale, brief version (WHOQOL-BREF). Ultimately, 667 patients were diagnosed with MDD, of 71.7% of whom had GAD. Compared to those with MDD alone, comorbid patients had lower scores on the physical (38.64 ± 10.35 vs.36.54 ± 12.32, P = 0.026) and psychological (35.54 ± 12.98 vs. 30.61 ± 14.66, P < 0.001) domains of the WHOQOL-BREF. The association between comorbid GAD and poor QOL on the two domains remained statistically significant in the multiple linear regression (unstandardized coefficients: -1.97 and -4.65, P < 0.001). In conclusion, the prevalence of comorbid GAD in MDD patients is high, and co-occurring GAD may exacerbate impaired physical and psychological QOL in Chinese MDD patients.
