Molecular Epidemiology regarding Mycobacterium tb ranges singled out through pulmonary tuberculosis patients throughout southern Ethiopia.
Given the long history of investigation into cancer and its relevance to the lymph node (LN), it would be meaningful to plot the trends of research on cancer-related LN.

Queries such as "cancer," "lymph node," and "cancer and lymph node" were submitted to PubMed to collect articles on cancer and LN published between 1945 and 2017. The collected articles were then extracted by an automatic web crawler and examined through informetrics and linguistic analysis.

The number of articles related to cancer was 2,795,476 and 127,897 articles (4.6%) were found to be relevant to LN. With regard to cancer types, breast cancer was the most studied (37%), followed by gastric cancer (17%). With regard to the subjects in which the surgeon is interested, LN metastasis (57%) was found to be the topic most discussed, followed by LN dissection (22%) and sentinel LN (17%). Publications on LN metastasis gradually increased over time from 1988 to 2017 although those on sentinel LN and LN dissection have stagnated since the early 2000s.

Although research on cancer was abundant, only a small portion was dedicated to investigating its relevance to LN. Western countries had led the research on cancer-related LN, but Asian countries began to participate as major players, expanding their contributions. While LN metastasis, one of the major cancer-related LN topics, showed a steady increase, those involved in oncologic surgery such as LN dissection and sentinel LN did not.

A cryopreserved iliac artery homograft (IAH) has not been considered suitable for middle hepatic vein (MHV) reconstruction during living donor liver transplantation (LDLT), primarily due to the low patency from its small diameter. We revised our surgical techniques for MHV reconstruction using an IAH to improve its patency.

This study analyzed the causes of early conduit occlusion and developed revised techniques to address this that had clinical application.

The potential risk factors for early conduit occlusion were the small IAH size, small graft in the segment V vein (V5) and segment VIII vein (V8) opening, and small recipient MHV-left hepatic vein stump. These factors were reflected to our revised surgical methods which included endarterectomy of the atherosclerotic plaque, unification of the internal and external iliac artery branches for large V5, and branch-patch arterioplasty for large V8. IAH endarterectomy, branch unification technique, and branch-patch arterioplasty were applied to 8, 5, and 5 patients, respectively and resulted in 1-month occlusion rates of 37.5%, 20.0%, and 40.0%, respectively. The overall patency rates of the IAH-MHV conduits in our 18 patients were 66.7% at 1 month, 38.9% at 3 months, and 33.3% at 1 year.

Our refined MHV reconstruction using an IAH improved short-term MHV conduit patency, but did not effectively prevent early conduit occlusion, particularly with a small- or medium-sized IAH. Compstatin Individualized reconstruction designs during LDLT operation are needed when an IAH is used for a modified right liver graft.

The aim of this study was to investigate how rates of surgical site infections (SSI) were changed over 2 years after applying colon SSI bundle in patients who underwent colon surgery.

The multidisciplinary working group developed a care bundle consisting of 8 components, including several recommendations of Surgical Care Improvement Project and monitoring of medical/surgical hand washing. We implemented the care bundle for each patient who underwent colon surgery from April 2013 to December 2014.

Overall bundle compliance was 87.9% before implementation, 88.2% in 2013, and 90.5% in 2014. In particular, compliance of the following 3 components was substantial improved during the project period; discontinuation of prophylactic antimicrobial agent within 24 hours of surgery (from 88.3% to 100%), surgical hand washing (from 50.0% to 78.9%), and medical hand washing (from 74.7% to 82.8%). The rate of SSI was 8.0% (12/150) during 3 months before implementation, 3.3% (16/480) from April to December in 2013, and 2.3% (14/607) in 2014.

After implementation of multidisciplinary care bundle, the compliance of each component was increased and rates of SSIs were significantly decreased compared to those before the quality improvement project.

Quality of life (QOL) has become important in the trend of emphasizing patient satisfaction. This study aimed to evaluate the QOL in patients who underwent laparoscopic or robotic gastrectomy for gastric cancer.

A prospective trial was performed involving patients who underwent laparoscopic or robotic gastrectomy for primary gastric cancer at 11 hospitals in Korea. Within this comparative trial, QOL, postoperative pain, and long-term complications were exanimated. The quality-of-life questionnaire (QLQ)-C30 and QLQ-STO22 developed by the European Organization for Research and Treatment of Cancer were used for the QOL survey. We compared the data after dividing it into several types of characteristics as follows; device (robotic or laparoscopic), operation type, pathological stage, and sex. Biased components were extracted by logistic regression analysis. Propensity score matching was applied to the data set with the biased components.

In total, 434 patients (211 for laparoscopic surgery and 223 for robotic surgery) were enrolled, out of which 321 patients who responded to both preoperative and postoperative surveys were selected for analysis.
