For accredited crime laboratories and other Forensic Science Service Providers (FSSPs) performing a method validation can be a time consuming and laborious process, particularly when performed independently by an individual FSSP. In this proposed collaborative method validation model, FSSPs performing the same task using the same technology are encouraged to work together cooperatively to permit standardization and sharing of common methodology to increase efficiency for conducting validations and implementation. FSSPs following applicable standards that are early to validate a method incorporating a new technology, platform, kit, or reagents are encouraged to publish their work in a recognized peer reviewed journal. Publication of validation data provides communication of technological improvements and allows reviews by others that supports the establishment of validity. It also permits other FSSPs to conduct a much more abbreviated method validation, a verification, if they adhere strictly to the method parameters provided in the publication by the original FSSP. By completing this verification, the second FSSP has reviewed and accepts the original published data and findings, thereby eliminating significant method development work. Utilization of published validation data increases efficiency through shared experiences and provides a cross check of original validity to benchmarks established by the originating FSSP. Utilization of the same method and same parameter set enables direct cross comparison of data and ongoing improvements. A business case will be provided to demonstrate the cost savings of the collaborative validation model using salary, sample and opportunity cost bases.In their analysis of recovered human remains, forensic anthropologists encounter structures of the throat (hyoid bone, thyroid cartilage/bone, cricoid cartilage/bone) that may present evidence of trauma. The recent published literature provides guidelines for the detection and interpretation of fractures in these tissues. Such traumatic injury frequently is associated with victims of hanging and strangulation, but many other causes have been recognized. Although the hyoid is not always recovered in skeletonized remains, it can reveal evidence of perimortem trauma and must be interpreted appropriately.
This study aims to understand patient factors associated with refusal of surgery for nonmetastatic colorectal cancer and the associated cancer-specific mortality.

Patients diagnosed with nonmetastatic colorectal cancer between 2004 and 2015 from the Surveillance, Epidemiology, and End Results Program were included.

A total of 152,731 (99.4%) patients underwent surgery, and 983 (0.6%) refused surgery. Independent predictors of refusal included male sex, older age, minority race, single relationship status, being uninsured, more recent date of diagnosis, having an earlier stage of diagnosis, and rectal versus colon cancer. Refusing surgery for nonmetastatic colorectal cancer increased cancer-specific mortality (adjusted hazard ratio 5.10, 95% confidence interval 4.62-5.62).

Most patients diagnosed with nonmetastatic colorectal cancer undergo surgery in the United States. However, refusal of surgery is increasing and associated with higher cancer-specific mortality. A better understanding of surgical decision making in colorectal cancer is urgently needed.

Limited studies have applied thoracic continuous spinal anesthesia in abdominal surgery, relying exclusively on opioids. This retrospective study analyzes 2 different schemes of thoracic continuous spinal anesthesia and postoperative analgesia in elderly patients undergoing major abdominal surgery.

A total of 98 patients aged ≥75 years were divided into 2 groups. The control group (60 patients) received bupivacaine plus fentanyl, whereas the study group (38 patients) received bupivacaine plus ketamine and midazolam. Both received analogous postoperative continuous intrathecal analgesia. Several perioperative variables were evaluated.

Spinal anesthesia was performed without complications in all patients. Doses of noradrenaline administered, incidence of respiratory depression, need for intraoperative sedation, and time to first flatus were significantly reduced in the bupivacaine plus ketamine and midazolam group.

In a population of frail, elderly patients, thoracic continuous spinal anesthesia with local anesthetic plus midazolam and ketamine was superior to local anesthetic plus fentanyl. In the group receiving local anesthetic plus midazolam and ketamine, the incidence of respiratory depression was reduced, and doses of norepinephrine and intraoperative sedating medications were lower. Intraoperative anesthesia and postoperative analgesia were similar in both groups.

We compare the performance of liver surface nodularity (LSN) and liver stiffness measurements (LSM) using transient elastography (TE) for the detection of clinically significant portal hypertension (CSPH) in patients with cirrhosis and hepatocellular carcinoma (HCC).

All patients with cirrhosis and HCC who underwent computed tomography, LSM and hepatic venous pressure gradient (HVPG) measurements within 30 days between 2015 and 2018 were included. The estimation of CSPH by LSN and LSM, and the LSM-spleen-size-to-platelet ratio score (LSPS) were evaluated and compared.

In total, 140 patients were included (109 men [78%], mean age 63 ± 9 years old), including 39 (28%) with CSPH. LSN measurements were valid in 130 patients (93%) and significantly correlated with HVPG (r= 0.68;
<0.001). Patients with CSPH had higher LSN measurements compared with those without [3.1 ± 0.4
