Ascaris is a helminthic parasite, which infects a wide range of host species causing ascariasis, a predominant disease worldwide. This parasite causes significant economic losses to the pig industry. The current study was designed to determine the Ascaris nematode by the genetic characterization of three mitochondrial (mt) genes namely NADH dehydrogenase subunit 1 (nad1), cytochrome oxidase subunit 1 (cox1) and cytochrome oxidase subunit 2 (cox2). A high infection rate of Ascaris nematode has been found in Tibetan pigs at the slaughter houses in Tibet Autonomous Region of China. The nad1, cox1 and cox2 genes sequences collected from adult Ascaris individuals were amplified by polymerase chain reaction. The cloned-amplicons and the positive products were sequenced and phylogenetic analysis was performed. The results indicated that the Ascaris infecting the Tibetan pigs were Ascaris suum (A. suum). This is the first report on the isolation, identification and genetic characterization of three mitochondrial genomes (nad1, cox1, and cox2) of A. suum originated from Tibetan pigs at high altitudes in Tibet.

BACKGROUND: Incisional hernia is a common complication following visceral organ transplantation. Transplant patients are at increased risk of primary and recurrent hernias due to chronic immune suppression and large incisions. We conducted a retrospective review of patients with a history of liver or kidney transplantation who underwent hernia repair to analyze outcomes and hernia recurrence. METHODS: This is a single center, retrospective review of 19 patients who received kidney and/or liver transplantation prior to presenting with an incisional hernia from 2011 to 2017. All hernias were repaired with open component separation technique (CST) with biologic mesh underlay. RESULTS: The mean age of patients was 61.0±8.3 years old, with a mean body mass index of 28.4±4.8 kg/m², 15 males (78.9%), and four females (21.1%). There were seven kidney, 11 liver, and one combined liver and kidney transplant patients. The most common comorbidities were hypertension (16 patients, 84.2%), diabetes (9 patients, 47.4%), and tobacco use (8 patients, 42.1%). Complications occurred in six patients (31.6%) including hematoma (1/19), abscess (1/19), seroma (2/19), and hernia recurrence (3/19) at mean follow-up of 28.7±22.8 months. With the exception of two patients with incomplete follow-up, all patients healed at a median time of 27 days. CONCLUSIONS: This small, retrospective series of complex open CST in transplant patients shows acceptable rates of long-term hernia recurrence and healing. By using a multidisciplinary approach for abdominal wall reconstruction, we believe that modified open CST with biologic mesh is a safe and effective technique in the transplant population with complex abdominal hernias.

Background & Objective: No clinical study of any interferon beta therapy has yet been successfully conducted in Chinese multiple sclerosis patients, probably due to the low incidence of this disease in China. The primary objective of this study was to demonstrate that treating multiple sclerosis patients of Chinese origin with interferon beta-1b has a beneficial effect on disease course, as measured by the decrease of newly active lesions on magnetic resonance imaging. Methods: Chinese patients diagnosed with relapsing-remitting or secondary-progressive multiple sclerosis were enrolled in this multicenter, open label, single-arm study. Following a 3-month pre-treatment phase, patients were treated with 250 µg interferon beta-1b subcutaneously every other day for 6 months. Patients had regular assessments for treatment safety and efficacy of the treatment. Results: Thirty seven patients completed the trial. Significant decreases in the number of newly active lesions were observed in the 6-month treatment period compared with the pre-treatment period (median decrease 1.5 lesions, p<0.001). Most adverse events were mild and transient and no serious ones were observed. Conclusions: Treatment with interferon beta-1b significantly reduced the occurrence of new lesions and was well tolerated in this Chinese population. These findings support the use of interferon beta- 1b for treating Chinese MS patients.

Objective: To analyze the effect of colorectal cancer screening in the general population in Guangzhou, and provide evidence for the for development of colorectal cancer screening policy and strategy. Methods: The data of colorectal cancer screening in Guangzhou during 2015- 2016 were collected. The participation, the positive rate of fecal occult blood test, the detection rate of colonoscopy and screening effect of colonoscopy were evaluated. Results: A total of 220 834 residents aged 50-74 years received the screening, and the positive rate of the screening was 16.77% (37 040 cases). Colonoscopy was performed for 7 821 cases (21.12%). Colorectal lesions were found in 4 126 cases (52.76%), of which 614 (7.85%) and 73 (0.93%) and 230 (2.94%) were identified as advanced adenoma, severe dysplasia lesions and colorectal cancers, respectively. The detection rates of all colorectal lesions were higher in men than in women (all P<0.01). The diagnostic rate of early lesion was 87.24%, and 99 early cancer cases were found, accounting for 46.26% of the total cases. The overall screening detection rate of colorectal cancer was 104.15/100 000, higher than the incidence rate (81.18/100 000) in colorectal cancer surveillance (P<0.001), but age group <70 years had higher detection rate, age group ≥70 years had higher incidence rate. Conclusions: The colorectal cancer screening strategy in Guangzhou is effective in the detection of the population at high risk, increase the detection rate of colorectal lesions, early diagnosis rate of precancerous lesions and diagnosis rate of early colorectal cancer. The benefit in those aged ≤69 years was more obvious than that in those aged 70-74 years. It is necessary to improve the compliancy of colorectal cancer screening in population at high risk.

Objective: The purpose of this study is to describe utilization, demographics, complications, and revisions for patients with degenerative spondylolisthesis (DS) with stenosis undergoing decompression or decompression with fusion in the United States. Methods: A national insurance database was used to identify patients who underwent either decompression and fusion or decompression alone for management of DS from 2010–2022. Utilization trends, demographics, and complications for each procedure were compared. Results: A total of 162,878 patients were identified, of which 78,043 patients underwent combined single-level lumbar decompression and fusion and 84,835 underwent single-level lumbar decompression alone. Between 2010–2021, lumbar decompression and fusion became the predominant surgical intervention for DS in 2016 and continued to account for more than half of all procedures during the remainder of the study period. Factors such as age, sex, comorbidities, geographic region, and physician specialty training were associated with procedure choice. Decompression with fusion was associated with a lower risk of revision surgery up to 5 years postoperatively and an overall lower incidence of 30-day complications. Conclusion Decompression with fusion has become the most common treatment for lumbar DS over the past decade despite a lack of compelling evidence supporting its use compared to decompression alone. A variety of patient and surgeon-specific factors is associated with procedure choice. After accounting for cofounders, we identified treatment-specific complications that may be valuable when counseling patients.
