    Numerous advances have been made in the field of spine fusion, such as minimally invasive (MIS) or robotic-assisted spine surgery. However, it is unknown how these advances have impacted the cost of care.

    Compare the economic outcomes of lumbar spine fusion between open, MIS, and robot-assisted surgery patients.

    Retrospective review of a single center spine surgery database.

    Three hundred sixty propensity matched patients.

    Costs, EuroQol-5D (EQ5D), cost per quality adjusted life years (QALY).

    Inclusion criteria surgical patients >18 years undergoing lumbar fusion surgery. Patients were categorized into 3 groups based on procedure type open, MIS, or robotic. Open patients undergoing poster spinal fusion were considered as the control group. MIS patients included those undergoing transforaminal or lateral lumbar interbody fusion with percutaneous screws. Robotic patients were those undergoing robot-assisted fusion. Propensity score matching was performed between all groups for the number of levelotic surgery cases, the projected costs per QALYs at life expectancy were well below established acceptable thresholds. The above findings may be reflective of an educational learning curve and emerging surgical technologies undergoing progressive refinement.

    The World Health Organization recommends routinely screening HIV-infected patients with CD4

    T-cell counts <100/μL for cryptococcal infection to prevent cryptococcal meningitis (CM), based on studies in Sub-Saharan Africa where the prevalence of positive cryptococcal antigen (CrAg+) is≥3% in this subgroup. Data about such prevalence in Spain are unavailable and rare in other European countries. BI-1347 mw Thus, the Spanish AIDS Study Group guidelines do not recommend routinely screening. We aim to determine the prevalence and outcomes of cryptococcal infection in this subgroup of patients in Spain.

    We determined CrAg using a lateral flow assay in banked plasma from participants in the cohort of the Spanish AIDS Research Network. Eligible patients had CD4

    T-cell counts ≤100/μL at the time of plasma collection and a follow-up >4weeks, unless they died.

    We included 576 patients from June 2004 to December 2017. Of these, 43 were CrAg+ for an overall prevalence of 7.5%. There were no differences depending on b these patients. Future studies should explore whether this recommendation could be firmly applied to other European populations.During development, highly dynamic reconstruction of microtubules is involved in many cellular processes, including cell division, migration, morphological changes, and material transportation within cells. Microtubule severing proteins (MSPs), with the function of cutting microtubules into short parts, are important regulators in the reconstruction of microtubule arrays. Fidgetin (fign) and its family members fidgetin like 1 (fignl1) and fignl2 are MSPs, and knowledge on the expression patterns of fign family members will benefit our understanding of their primary roles in one specific stage during development. In this study, we compared the evolutionary relationships of fign family members and found that fignl2 is closer to fign than fignl1. We utilized the zebrafish model and in situ hybridization (ISH) to parallelly identify the expression features of fign family members. Our findings revealed that before 12 h post fertilization (hpf), the expression patterns of fign and fignl1 and fignl2 genes were similar, but differences arose thereafter. Fignl2 transcripts were present in more tissues and organs of zebrafish after 12 hpf and potentially exhibited more ubiquitous functions. This study is the first to assess systematic comparable data on the expression patterns of fign family members during development.Seasonal timing is important for many critical life history events of vertebrates, and photoperiod is often used as a reliable seasonal cue. In mammals and birds, it has been established that a photoperiod-driven seasonal clock resides in the brain and pituitary, and is driven by increased levels of pituitary thyroid stimulating hormone (TSH) and brain type 2 iodothyronine deiodinase (DIO2), which leads to local increases in triiodothyronine (T3). In order to determine if a similar mechanism occurs in fish, we conducted photoperiod manipulations in anadromous (migratory) Atlantic salmon (Salmo salar) that use photoperiod to time the preparatory development of salinity tolerance which accompanies downstream migration in spring. Changing daylength from short days (lightdark (LD) 1014) to long days (LD 168) for 20 days increased gill Na+/K+-ATPase (NKA) activity, gill NKAα1b abundance and plasma growth hormone (GH) levels that normally accompany increased salinity tolerance of salmon in spring. Long-day exposure resulted in five-fold increases in pituitary tshβb mRNA levels after 10 days and were sustained for at least 20 days. tshβb mRNA levels in the saccus vasculosus were low and not influenced by photoperiod. Increased daylength resulted in significant increases in dio2b mRNA levels in the hypothalamus and midbrain/optic tectum regions of the brain. The results are consistent with the presence of a photoperiod-driven seasonal clock in fish which involves pituitary TSH, brain DIO2 and the subsequent production of T3, supporting the hypothesis that this is a common feature of photoperiodic regulation of seasonality in vertebrates.Radiation-induced intestinal injury (RIII) occurs during instances of intentional or accidental radiation exposure. However, there are few effective treatments available for the prevention or mitigation of RIII currently. (-)-Epigallocatechin-3-gallate (EGCG), a major polyphenol in green tea, possesses potent antioxidant activity and has been shown to be effective in ameliorating many oxidative stress-related diseases. The therapeutic effects and mechanism of EGCG on RIII have not yet been determined. In the present study, we investigated whether EGCG confers radioprotection against RIII. Our data demonstrated that administration of EGCG not only prolonged the survival time of lethally irradiated mice, but also reduced radiation-induced intestinal mucosal injury. Treatment with EGCG significantly increased the number of Lgr5+ intestinal stem cells (ISCs) and their progeny Ki67+ cells, and reduced radiation-induced DNA damage and apoptosis. Besides, EGCG displayed the same radioprotective effects in human intestinal epithelial HIEC cells as in mice, characterized by a decrease in the number of γH2AX foci and ferroptosis.
