Mendelian randomization study on association between grip strength and BMD in different age groups.

INTRODUCTION: This study aimed to use the Mendelian randomization study method to verify the causal relationship between grip strength and bone mineral density (BMD) in different ages and different parts of the body. MATERIALS AND METHODS: The analysis was based on pooled data from genome-wide association studies (GWAS). Hand grip strength (right) was used as the exposure variable and total body bone mineral density (BMD) of different age groups was used as the outcome variable. Single-nucleotide polymorphisms highly correlated with exposure variables were used as instrumental variables. The inverse variance weighted (IVW) method was used as the primary analysis method, and the Mendelian randomization Egger (MR-Egger) regression and weighted median methods were used as supplementary evidence for the IVW results. Horizontal pleiotropy and heterogeneity tests were conducted to ensure the stability of the results. RESULTS: Analyzing the GWAS data on osteoporosis as the outcome variable, the IVW analysis showed that osteoporosis risk was associated with decreased grip strength in the 45-60 age group and the risk of declining lumbar spine BMD was associated with decreased grip strength. However, there was no significant correlation between the risk of osteoporosis in other age groups and changes in grip strength. CONCLUSION: A causal relationship exists between decreased grip strength and osteoporosis risk in people aged 45-60 years. The risk of BMD declining in the lumbar spine was associated with reduced grip strength.

Efficacy and safety of oral traditional Chinese medicine combined with conventional anti-osteoporosis drugs for osteoporosis and fractures: A meta-analysis of randomized controlled trials.

OBJECTIVE: To evaluate the efficacy and safety of oral traditional Chinese medicine combined with conventional anti-osteoporosis drugs in the treatment of osteoporosis and fractures. METHODS: The database of China national knowledge infrastructure, China Science and Technology Journal Database, Wangfang (WANGFANG DATA), ChineseBioMedicalLiteratureDatabase, PubMed, Embase, and Cochrane Library databases were searched from inception to June 1st, 2023 for randomized controlled trials on oral Chinese medicine combined with conventional anti-osteoporosis drugs for the treatment of osteoporosis and fractures. Quality assessment was performed using the Cochrane Handbook for Systematic Reviews of Interventions version 5.1.0. STATA 15.0 software was used for meta-analysis. Outcome measures included overall response rate, adverse events, T-score, bone mineral density, Oswestry Disability Index score, fracture healing time, and visual analog scale score. RESULTS: A total of 72 studies were included, involving 7847 participants. Different treatment options showed different advantages in the adjuvant treatment of osteoporosis and fractures. The total response rate, complication reduction, Oswestry Disability Index and visual analog scale score reduction, bone mineral density improvement and fracture healing time were all superior to drug therapy alone. The differences were statistically significant, but the improvement in T-score was not significant. CONCLUSION: The combination of oral traditional Chinese medicine and conventional anti-osteoporosis drugs is more effective and safer than Western medicine alone in the treatment of osteoporosis and fractures, which indicated that the treatment of integrated Chinese and western medicine can promote the healing of osteoporosis and fracture. This approach had a promising clinical application prospect. Due to the limitations of included studies, the ranking results should be interpreted with caution. In the next step, we will further conduct subgroup data based on factors, such as conventional Western medicine treatment regimens, whether surgical treatment was performed, fracture locations.

Multiple tophi deposits in the spine: A case report.

BACKGROUND: Spinal gout (SG) is a rare condition. So far, a limited number of cases have been reported. Herein, we reported a single case of a 42-year-old male patient with SG involving the cervicothoracic and lumbar spine who underwent cervicothoracic segmental surgery. CASE SUMMARY: The patient presented to the hospital with neck pain and limb weakness lasting for one month. He had a history of gout for more than 10 years. Clinical and imaging findings indicated bone and joint tophus erosion, and the patient underwent standard tophi excision and internal fixation with a nail-and-rod system. Histopathological examination suggested gout-like lesions. After the operation, the patient's spinal nerve symptoms disappeared, and muscle strength gradually returned to normal. The patient maintained a low-purine diet and was recommended to engage in healthy exercises. The patient recovered well. CONCLUSION: Clinicians should highly suspect SG when patients with chronic gout presented with low back pain and neurological symptoms. Early decompression and debridement surgery are important to relieve neurological symptoms and prevent severe secondary neurological deficits.
