We aimed to test the utility of screening for depressive symptoms in the hand surgical office focusing on chances of heightened depressive symptoms in patients with no history of diagnosed depression and by quantifying ongoing depressive symptoms among patients diagnosed with depression accounting for antidepressant use. The clinical importance of this study was predicated on the documented negative association between depressive symptoms and hand surgical outcomes. This cross-sectional study analyzed 351 patients presenting to a tertiary hand center between April 21, 2016, and November 22, 2017. Adult patients completed self-administered Patient-Reported Outcomes Measurement Information System (PROMIS) Depression computer adaptive tests at registration. Health records were examined for a past medical history of diagnosed depression and whether patients reported current use of prescription antidepressants. Mean PROMIS Depression scores were compared by analysis of variance (groups no diagnosed depression, 3 patients diagnosed with depression as having currently heightened depressive symptoms. Hand surgeons can use PROMIS Depression screening in all patients and using this to guide referrals for depression treatment to ameliorate one confounder of hand surgical outcomes. Symptom prevalence study II.Symptom prevalence study II. To compare the sensitivity and specificity of high-resolution static and dynamic ultrasound (US) for diagnosing intact repairs and small, clinically relevant gaps (≥4 mm) in repaired flexor digitorum profundus tendons within zone 2 and, secondarily, to evaluate the effect of suture artifact from 3 commonly used suture types. Eighty-eight fresh-frozen cadaveric digits (thumbs excluded) were randomized to either an intact repair (0-mm gap) or repairs using a locked 4-strand suture repair with either 4-0 Prolene, Ethibond, or FiberWire and gaps of 2, 4, or 6 mm and no suture in which 2-, 4-, or 6-mm gaps were created without a suture crossing the repair site. Gap widths were estimated by a blinded musculoskeletal ultrasonographer in static and dynamic modes. Both static and dynamic modalities tended to overestimate actual gap sizes. For the suture gaps, both modalities had poor sensitivity (29% static; 42% dynamic) for accurately diagnosing a clinically intact repair (<4 mm), but better specificity (83%d repair is likely in about 80% of cases. click here A gap measurement of less than 5 mm may miss a high percentage of repairs that are clinically failed.Osteogenic sarcoma is a malignant tumor that rarely affects the hand. When it does, it most often involves the phalanges or metacarpal heads. We present the case of a 51-year-old woman with a low-grade osteosarcoma affecting the trapezium bone of her left hand. A total trapeziectomy with partial removal of the first metatarsal, scaphoid, trapezoid, and capitate bones was performed, and no adjuvant therapy was administered. Six years after the intervention, the patient is disease-free, with excellent functionality and yearly imaging tests showing no signs of recurrence.Polycyclic aromatic hydrocarbons (PAHs) in river sediments in China have been extensively investigated. However, most previous studies only reported information about specific locations. As a result, the distribution and changes of these chemicals in sediments nationwide remain unknown. Based on published data during 1997-2020, we conducted a systematic meta-analysis to understand the concentration, risk and the spatiotemporal variation of PAHs in river sediments from the seven major river systems in China. The report provides a national picture of PAHs in river sediments of China. Among the seven river systems, higher concentrations of sediment PAHs are found in the basins of Liaohe River and Haihe River. In the study sediments, high-molecular-mass (4-6-ring) PAHs were predominated, reflecting the widespread combustion of coal and fossil fuels across China. In addition, PAH source assessment also suggests that raw coal and crude oil are important contributors to PAH concentrations in the rivers in northeastern China. Over the past 20 years, there is no downward trend in the concentrations of Σ16PAHs in sediments in the seven river basins; but the contribution of high-temperature combustion to the pollution has declined. In addition, our calculated risks from sediment PAHs seem to decline between 1997-2006 and 2007-2017 periods, although the differences were not statistically significant (p > 0.05). Of note, the data collection and the risk assessment methods used in this preliminary survey may result in some uncertainty. Our results suggest that the PAHs in river sediments in China still need to be paid attention to due to the complexity of their sources and harms to aquatic organisms.Electroplating sludge (ES) is a waste that is generated by the galvanization industry and is highly toxic because it contains heavy metals. This study examined the physiochemical properties of ES residue, the recovery of the present metals, and the reuse of these metals to add value to this residue and avoid environmental contamination through its inadequate disposal. The potential for leaching of ES was investigated using various tests, and a decrease in the germination speed of Lactuca sativa seeds and the appearance of chromosomal aberrations in the cytotoxicity tests were observed. The reduction of the pH and dynamic leaching conditions favor the leaching of ES heavy metals. An increase in the ES concentration in soil decreases the speed of germination and increases the number of chromosomal aberrations that are related to aneugenic phenomena that promote tumor development. Metals were recovered through solubilization, followed by selective precipitation. The recovery of heavy metals from ES decreased its toxicity by eliminating toxic components. The reuse of the metals in the electroplating process may reduce the cost of disposal of ES, thereby rendering it an economically and environmentally friendly alternative. The products that were galvanized using the recovered solution showed the best results in the corrosion test, thereby demonstrating the viability of the use of this solution in industrial galvanization.
