Hand and wrist research has recently shown obvious progress. The quantity and quality of publications from different nations, however, have not been analyzed. In our study, we aimed to assess the characteristics of worldwide productivity in hand and wrist literature using highly cited subspecialty journals. ⋯ The number of publications of hand and wrist research shows a significant increase during the past 10 years. The United States is the most productive country in hand and wrist literature. However, some European countries and Australia may have higher quality of articles according to mean 5y-IF and mean citations per article.

In recent years, nucleus pulposus cell (NPC) transplantation has been used to treat intervertebral disc degeneration (IDD); however, the degenerative nature of NPCs influences its effectiveness. Nucleus pulposus-derived stem cells (NPSCs), which are self-renewing, have high expansion potential and can adapt to the intervertebral disc (IVD) microenvironment and may have a better regenerative capacity, which is favourable for treating IDD. The aim of this study was to compare the effectiveness of transplantation with NPSCs and NPCs on the regeneration of the IVD in rabbit models. ⋯ Compared to NPCs, NPSCs harvested by differential adhesion method displayed a higher positive rate of stem cell surface markers and showed superior regenerative effectiveness for treating IDD in rabbit models. Therefore, NPSCs are potential candidates for cell therapy for the regeneration of the IVD.

Review Meta Analysis
The impact of intraoperative vascular occlusion during liver surgery on postoperative peak ALT levels: A systematic review and meta-analysis.
Intraoperative vascular occlusion techniques during liver surgeries have been performed and refined for decades. However, the impact of these techniques on postoperative peak ALT levels remains uncertain. Thus, we performed a literature review and meta-analysis to determine the impact of intraoperative vascular occlusion during liver surgery on postoperative peak ALT levels. ⋯ Intraoperative vascular occlusion, especially intermittent inflow occlusion and Pringle's maneuver vascular occlusions, may be a potential risk factor that could lead higher postoperative peak ALT values than non-occlusion procedures for liver surgeries.

The objective of this systematic review was to identify the effectiveness of percutaneous endoscopic lumbar discectomy (PELD) in the treatment of recurrent lumbar disc herniation (rLDH) and to present its indications and techniques. We conducted a comprehensive search in MEDLINE, EMBASE, PubMed, Web of Science and Cochrane databases, searching for relevant studies of managing rLDH with PELD up to July 2015. Only papers published in English were included. ⋯ In conclusion, according to the current evidence, PELD is an effective procedure for the treatment of rLDH in terms of reducing complication and shorting hospital course, comparing with OD. Therefore, we suggested that PELD was a feasible alternative to OD in the treatment of the rLDH in the condition of proper indication. High-quality RCTs with large sample sizes are needed to further confirm these results.

Operative notes are the recognized standard for documenting the details of an operation yet key procedural details are frequently missing. With the aim of improving standards, based on the Royal College of Surgeons (RCS) and Dutch Society of Surgery (DSS) Guidelines, we introduced an operation note proforma for use following laparoscopic cholecystectomy in a tertiary centre in the UK. ⋯ We have demonstrated that the introduction of a procedure-specific proforma to assist with writing the post-operative note following laparoscopic cholecystectomy can result in significant improvements in documentation of generic and procedure-specific items that should be recorded for every operation. Procedure-specific proformas, based on established guidelines can help to produce more complete and medico-legally robust operation notes.
