Background: Facial rejuvenation techniques using thread lifts are performed by passing sutures under the facial skin to treat sagging and facial flaccidity, and their advantages include a relatively short recovery time and relatively small incisions. In this study, we describe the short-term safety of a facial rejuvenation technique involving an absorbable polydioxanone monofilament thread (Mint Lift) in patients with mild-to-moderate facial skin sagging. Methods: The current multicenter, retrospective, case-series study was conducted in a total of 196 patients who visited the Grace Plastic Surgery Clinic or the Songdo IB Clinic between 2016 and 2018. The patients underwent insertion of the Mint Lift 43 and 17 in the deep temporal fascia and the deep subcutaneous layer, respectively. Of these patients, 179 met the eligibility criteria and their medical records were retrospectively reviewed. Results: The patients comprised six men (3.4%) and 173 women (96.6%), with a mean age of 44.4±14.4 years. In our series, postoperative complications included ecchymosis (1.7%), infection (0.4%), thread extrusion (1.1%), and skin dimpling (1.5%). No cases of iatrogenic nerve injury were observed, and all postoperative complications spontaneously resolved. Conclusions The Mint Lift 43 and 17 may be safe for thread lifting in patients with mildto-moderate facial skin sagging. However, further long-term follow-up studies are warranted.

This study surveyed the prevalence of traumatic reticular diseases (TRD) of slaughter cattle in Korea, the typology of the causative foreign bodies and the effects on beef quality and carcass weight. The overall prevalence of TRD in 3,121 slaughter cattle was 5.5%. However, the prevalence was significantly higher in Korea indigenous cattle Hanwoo (5.8%, p < 0.05) and female cattle (20.75%, p < 0.001). The prevalence significantly increased in aged cattle (p < 0.001). Major lesions related to foreign bodies were reticulitis (96%) and peritonitis (86%). Most causative foreign bodies were made of iron including nails, wires, steel rods, screw nails, and syringe needles. Cattle affected with TRD produced significantly lower grade quality of beef compared to normal cattle (p < 0.0001), but TRD did not affect carcass weight. The data will be useful in the management of TRD, with the aim of increasing beef productivity in Korea.

Mycobacterium (M.) bovis, a bacterium in the M. tuberculosis complex, is a causative agent of bovine tuberculosis, a contagious disease of animals. Mycobacterial culture is the gold standard for diagnosing bovine tuberculosis, but this technique is laborious and time-consuming. In the present study, performance of the SD Bioline TB Ag MPT4 Rapid test, an immunochromatographic assay, was evaluated using reference bacterial strains and M. bovis field isolates collected from animals. The SD MPT64 Rapid test produced positive results for 95.5% (63/66) of the M. bovis isolates from cattle and 97.9% (46/47) of the isolates from deer. Additionally, the test had a sensitivity of 96.5% (95% CI, 91.2-99.0), specificity of 100% (95% CI, 96.7-100.0), positive predictive value of 100% (95% CI, 96.7-100.0), and negative predictive value of 92.9% (95% CI, 82.7-98.0) for M. bovis isolates. In conclusion, the SD MPT64 Rapid test is simple to use and may be useful for quickly confirming the presence of M. bovis in animals.

The aim of this study was to investigate the molecular characteristics and to conduct a comparative genomic analysis of Mycobacterium (M.) bovis strain 1595 isolated from a native Korean cow. Molecular typing showed that M. bovis 1595 has spoligotype SB0140 with mycobacterial interspersed repetitive units-variable number of tandem repeats typing of 4-2-5-3-2-7-5-5-4-3-4-3-4-3, representing the most common type of M. bovis in Korea. The complete genome sequence of strain 1595 was determined by single-molecule real-time technology, which showed a genome of 4351712 bp in size with a 65.64% G + C content and 4358 protein-coding genes. Comparative genomic analysis with the genomes of Mycobacterium tuberculosis complex strains revealed that all genomes are similar in size and G + C content. Phylogenetic analysis revealed all strains were within a 0.1% average nucleotide identity value, and MUMmer analysis illustrated that all genomes showed positive collinearity with strain 1595. A sequence comparison based on BLASTP analysis showed that M. bovis AF2122/97 was the strain with the greatest number of completely matched proteins to M. bovis 1595. This genome sequence analysis will serve as a valuable reference for improving understanding of the virulence and epidemiologic traits among M. bovis isolates in Korea.

Human Q fever, a zoonosis caused by Coxiella burnetii, presents with diverse clinical manifestations ranging from mild self-limited febrile illnesses to life-threatening complications such as endocarditis or vascular infection. Although acute Q fever is a benign illness with a low mortality rate, a large-scale outbreak of Q fever in the Netherlands led to concerns about the possibility of blood transfusion-related transmission or obstetric complications in pregnant women. Furthermore, a small minority (< 5%) of patients with asymptomatic or symptomatic infection progress to chronic Q fever. Chronic Q fever is fatal in 5–50% of patients if left untreated. In South Korea, Q fever in humans was designated as a notifiable infectious disease in 2006, and the number of Q fever cases has increased sharply since 2015. Nonetheless, it is still considered a neglected and under-recognized infectious disease. In this review, recent trends of human and animal Q fever in South Korea, and public health concerns regarding Q fever outbreaks are reviewed, and we consider how a One Health approach could be applied as a preventive measure to prepare for zoonotic Q fever outbreaks.
