Comparison of Thyroglobulin and Thyroid Function in Pregnant Women between Counties with a Median Urinary Iodine Concentration of 100-149 µg/L and 150-249 µg/L.

Objective: This study explored whether thyroglobulin and thyroid disease prevalence rates were higher in pregnant Chinese women with a median urinary iodine concentration of 100-149 µg/L, compared with those with a median urinary iodine concentration of 150-249 µg/L maintained through sustainable universal salt iodization. Methods: This was a cross-sectional study in which 812 healthy pregnant women were enrolled to collect samples of their household edible salt, urine, and blood during their routine antenatal care in the 18 counties in Fujian Province, China. The levels of salt iodine concentration, urinary iodine concentration (UIC), free triiodothyronine (FT3), free thyroid hormone (FT4), thyroid-stimulating hormone (TSH), thyroglobulin (Tg), thyroid peroxidase antibody and thyroglobulin antibody were assessed during the routine antenatal care visits. Results: The median UIC (mUIC) in pregnant women was 130.8 µg/L (interquartile range = 91.5-198.1 µg/L) in the counties with an mUIC of 100-149 µg/L (Group I), and 172.0 µg/L (interquartile range = 123.5-244.4 µg/L) in the counties with an mUIC of 150-249 µg/L (Group II). Goiter prevalence and thyroid nodule detection rates showed no difference between Group I and Group II ( P > 0.05). Except for FT4 values, the TSH, FT4, FT3, Tg and Tg values > 40 (µg/L) and the thyroid diseases prevalence rate (TDR) showed no significant differences between Group I and Group II ( P > 0.05), whether or not iodine supplementation measures were taken. Conclusion: Compared with an mUIC of 150-249 µg/L, not only there was no difference in thyroid morphology, but also the Tg value, rate of Tg values > 40 µg/L, and TDR were not higher in pregnant women in the counties with an mUIC of 100-149 µg/L achieved through sustainable universal salt iodization in Fujian Province, China.

Nucleus accumbens deep brain stimulation improves depressive-like behaviors through BDNF-mediated alterations in brain functional connectivity of dopaminergic pathway.

Major depressive disorder (MDD), a common psychiatric condition, adversely affects patients' moods and quality of life. Despite the development of various treatments, many patients with MDD remain vulnerable and inadequately controlled. Since anhedonia is a feature of depression and there is evidence of leading to metabolic disorder, deep brain stimulation (DBS) to the nucleus accumbens (NAc) might be promising in modulating the dopaminergic pathway. To determine whether NAc-DBS alters glucose metabolism via mitochondrial alteration and neurogenesis and whether these changes increase neural plasticity that improves behavioral functions in a chronic social defeat stress (CSDS) mouse model. The Lab-designed MR-compatible neural probes were implanted in the bilateral NAc of C57BL/6 mice with and without CSDS, followed by DBS or sham stimulation. All animals underwent open-field and sucrose preference testing, and brain resting-state functional MRI analysis. Meanwhile, we checked the placement of neural probes in each mouse by T2 images. By confirming the placement location, mice with incorrect probe placement (the negative control group) showed no significant therapeutic effects in behavioral performance and functional connectivity (FC) after receiving electrical stimulation and were excluded from further analysis. Western blotting, seahorse metabolic analysis, and electron microscopy were further applied for the investigation of NAc-DBS. We found NAc-DBS restored emotional deficits in CSDS-subjected mice. Concurrent with behavioral amelioration, the CSDS DBS-on group exhibited enhanced FC in the dopaminergic pathway with increased expression of BDNF- and NeuN-positive cells increased dopamine D1 receptor, dopamine D2 receptors, and TH in the medial prefrontal cortex, NAc, ventral hippocampus, ventral tegmental area, and amygdala. Increased pAMPK/total AMPK and PGC-1α levels, functions of oxidative phosphorylation, and mitochondrial biogenesis were also observed after NAc-DBS treatment. Our findings demonstrate that NAc-DBS can promote BDNF expression, which alters FC and metabolic profile in the dopaminergic pathway, suggesting a potential strategy for ameliorating emotional processes in individuals with MDD.

Pharmacists promote rational use of antibiotic prophylaxis in Type I incision operations via application of drug use evaluation.

OBJECTIVE: Drug use evaluation (DUE) criteria were established to assess the rational use of antibiotic prophylaxis (RUAP) in Type I incision operations (TOIO) during peri-operation period and to enhance pharmacists' responsibilities for antibiotic stewardship. METHODS: The criteria were set with a threshold based on a literature review and discussions with multidisciplinary experts. Patients who received TOIO from July 2008 to June 2012 were enrolled in the study. The percentage of prescriptions adhering to all items of criteria was 10% at baseline. RESULTS: According to DUEs and interviews by pharmacists, the percentages of prescriptions adhering to all items of criteria of DUE-1, DUE-3, DUE-5, and DUE-8 were 13.3, 20.0, 50.0 and 66.7%, respectively. The study showed that the most common inappropriate therapies were no indications for prophylaxis antibiotic use and inappropriate choices of antibiotics. Pharmacists finally disseminated DUE criteria and reports to prescribe and improve RUAP in TOIO at the hospital through the Drug and Therapeutics Committee (DTC). CONCLUSION: The study demonstrated that application of pharmacist- directed DUE is a useful strategy to detect, supervise and help correct challenges encountered during antibiotic prophylaxis in TOIO.

[Clinical analysis of CT guided unilateral PVP for the treatment of osteoporotic vertebral compression fracture in senile patients].

OBJECTIVE: To evaluate the therapeutic effect and security of CT guided unilateral percutaneous vertebroplasty (PVP) for the treatment of osteoporotic vertebral compression fracture (OVCF) in senile patients. METHODS: From April 2009 to June 2010, 26 patients undergoing CT guided unilateral percutaneous vertebroplasty were analyzed retrospectively. There were 9 males and 17 females,ranging in age from 60 to 85 years with an average of (67.50+/-6.76) years, ranging in course of disease from 2 to 30 days with an average of (8.92+/-4.36) d. The affected segments involved 35 vertebras. The major clinical manifestations of OVCF were lumbar-back pain (especially when turning over or stooping down) and unable to bear. The needle was punctured into vertebral of lesions through unilateral puncture under the CT guidance; and then 3-5 ml bone cement was injected into vertebral. Antibiotic was used 3 days to prevent postoperative infections. Postoperative complications were observed after operation, such as local leakage of bone cement, penetrating spinal cord and/or segmental spinal nerve injuries and pulmonary embolism. X-ray was used to measure the height of anterior, middle and exterior of vertebral before and after treatment. A visual analog scale (VAS) scoring was applied to evaluate pain score preoperative, 48 hours postoperative and the terminal follow-up. RESULTS: Twenty-six patients achieved success in punctuation without serious complications. Local leakage of bone cement occurred in 6 cases, but without clinical symptoms or signs. One patient suffered from acute intraoperative reactions to bone cement and relieved by 5 mg dexamethasone and oxygen. All patients were followed up for 6 to 12 months [averaged (8.4+/-1.6) months]. The postoperative vertebrae height was higher than preoperative,but there was no statistical difference between postoperative and preoperative (P>0.05). Preoperative VAS scores was 7.63+/-0.92, postoperative score was 3.00+/-1.09, the final follow-up score was 2.38+/-1.17; there was significant difference between preoperative and postoperative at 48 hours (P<0.05), but there was no statistical difference between final follow-up and postoperative at 48 hours (P>0.05). CONCLUSION: Unilateral PVP under CT guided can increase the vertebral strength and stabilize vertebral body,and the procedure is a safe and effective method for OVCF in elderly patients.
