Sampling of prostate tissue (n = 97) was performed in conjunction with planned radical prostatectomies, in collaboration with Biobank1®. The tissue used in this study was collected during the period 2003-2016, quickly frozen, and kept at -80°C until assayed in 2018. RNA extraction was performed with two different protocols (miRNeasy and mirVana™), and RNA quality was determined by measuring the RNA Integrity Number (RIN). The level of isoprostanes is widely recognized as a specific indicator of lipid peroxidation both in vitro and in vivo. The level of 8-isoprostane was measured because it is the main oxidation product of arachidonic acid, the most abundant phospholipid fatty acid. The level of 8-isoprostane was measured using enzyme immunoassay. There was no statistically significant difference in yield between the samples isolated with the mirVana protocol compared to the miRNeasy protocol. Average RIN was 2.8 units higher with the mirVana extraction protocol compared to the miRNeasy protocol (p  less then  0.001). For miRNeasy extractions, RINs were 7.1 for prostatectomies in 2005-2007 and 6.2 for those in 2018 (p  less then  0.001). For mirVana extractions, the difference in RIN score between the two groups regarding years of collection was not statistically significant. There was no significant increase in the levels of 8-isoprostane between the 2005-2007 samples and the 2018. The conclusion is that there is no oxidation of phospholipids with increasing storage time up to 15 years.Background Gender-affirming surgery may be pursued by individuals experiencing gender dysphoria. Although genital and chest procedures are classified as medically necessary, facial feminization surgeries (FFSs) are often considered cosmetic. Insurance companies may limit coverage of these procedures, especially in states less supportive of transgender individuals. Objectives To determine insurance coverage and ease of finding policy information for FFSs, and to analyze differences based on state advocacy. Methods Insurance policies for the top three commercial health plans per state were reviewed. Coverage status was determined by web-based search and telephone interviews. Ease of gathering policy information was assessed using a post-task questionnaire graded on a 7-point Likert scale, with higher numbers (e.g., 7) representing relative ease. State advocacy was determined by the number of state laws and policies affecting the transgender community. Results Of the 150 insurance policies, only 27 (18%) held favorable policies for FFS. Most favorable companies covered chondrolaryngoplasty, with 78% (n = 21) offering preauthorization. Mean ease of use was rated 6, with 12 companies requiring a telephone interview. Insurance policies in states with laws driving transgender equity covered more FFS procedures (p = 0.043), whereas those in restrictive states offered less overall coverage (p = 0.023). Tacrolimus mouse Conclusions FFS is rarely covered by commercial insurance companies, especially in states with less legal support for transgender individuals. Policy information remains difficult to obtain, with variable coverage by employer and no standardized medical necessity criteria. Limited coverage, lack of easily accessible information, and absence of universal criteria may act as barriers to FFS.

Adjacent segment degeneration (ASD) is a well-known problem of posterior lumbar interbody fusion (PLIF). A device for interspinous assisted motion (DIAM) has been recently applied at the adjacent segment to pedicle screw instrumentation to create a dynamic transition zone. The aim of this study was to determine whether DIAM implantation at the adjacent segment could reduce the occurrence of radiologic and symptomatic ASD.

This retrospective study reviewed 51 patients who underwent PLIF with or without DIAM between 2005 and 2016. They were followed up for more than 24 months. The mean follow-up was over 5 years. Fourteen patients underwent PLIF with DIAM implantation at the cephalad level (Group A) and 37 patients received PLIF only (Group B). In radiologic ASD, several parameters were measured using pre- and post-operative radiographs and magnetic resonance image for lumbar degenerative disease and paraspinal muscle. Visual analogue scale (VAS) and Roland-Morris Disability Questionnaire (RMDQ) scores of bcould help slow the progression of both radiologic and symptomatic ASD.

The spectrum of post-operative infections in neurosurgical practice includes scalp infection, bone flap osteomyelitis, meningitis and intracranial abscesses and is associated with significant morbidity and mortality. There is a wide variation across neurosurgical centres in the use of perioperative antibiotic prophylaxis. The aim of this study was to determine whether intraoperative wound irrigation with ceftriaxone provides additional prevention of surgical site infection (SSI) in patients already receiving the drug parenterally.

This was a prospective randomized clinical study of patients 18 years and above scheduled for clean neurosurgical procedures and assigned to either study or control group using table of random numbers. Both groups had parenteral ceftriaxone at the induction of anaesthesia and for 24-h post-operation. In the study group, there was intra-operative wound irrigation with a ceftriaxone-in-normal saline solution while the wound in the control group was irrigated with only normal salinch prophylactic intravenous antibiotics were administered to the patient. Wound edge necrosis was the most significant but preventable risk factor for the development of SSI in the setting of this work.

Hepatic fibrosis is the excessive synthesis and deposition of extracellular matrix including collagen in the tissue. Chronic liver insult leads to progressive parenchymal damage, portal hypertension, and cirrhosis. Determination of hepatic collagen by invasive liver biopsy is the gold standard to estimate severity and stage of fibrosis. However, this procedure is associated with pain, carries the risk of infection and bleeding, and is afflicted with a high degree of sampling error. Therefore, there is urgent need for serological collagen-derived markers to assess collagen synthesis/turnover.

Biochemical properties of collagens, cellular sources of hepatic collagen synthesis, and regulatory aspects in collagen expression. Markers are discussed suitable to estimate hepatic collagen synthesis and/or turnover. Discussed studies were identified through a PubMed search done in May 2020 and the authors' topic knowledge.

Hepatic fibrosis is mainly characterized by accumulation of collagen-rich scar tissue. Although traditionally performed liver biopsy is still standard in estimating hepatic fibrosis, there is evidence that noninvasive diagnostic scores and collagen-derived neo-epitopes provide clinical useful information.
