A Prospective Study Comparing Quality of Life after Laparoscopic Donor Nephrectomy versus Open Donor Nephrectomy

Laparoscopic donor nephrectomy (LDN) has advantages over open donor nephrectomy (ODN), with less bleeding and pain, and earlier discharge. However, the quality of life (QOL) has not been compared between these techniques. All consecutive donors undergoing left LDN or ODN from 2013 to 2015 at our center were included. The donors' QOL was measured with the brief World Health Organization QOL (WHOQOL-BREF) and the Hospital Anxiety and Depression Scale (HADS) questionnaires preoperatively and at 3 and 6 months postoperatively. Cosmesis was measured by the body image questionnaire, and patient satisfaction was scored on a verbal rating scale at 3 and 6 months. Of the 264 donors, 228 met the inclusion criteria (100 – LDN and 128 – ODN). The LDN group showed no difference in WHOQOL-BREF scores at 3 months, and significant improvements in the psychological and social domains at 6 months versus the baseline. The ODN group showed a significant decrease in the physical, psychological, and environmental domains at 3 and 6 months versus the baseline. Compared with the ODN group, the LDN group had better QOL scores at 3 and 6 months in all domains. The responses to the HADS questionnaire were similar between the groups at all time points. The mean body image, cosmesis, and satisfaction scores were significantly better in the LDN group. LDN minimized the negative effects of surgery on the donors' QOL, with improvements in the long-term psychological and social aspects versus the baseline. LDN was more cosmetic and was associated with higher satisfaction than ODN

A prospective randomised controlled trial comparing chronic groin pain and quality of life in lightweight versus heavyweight polypropylene mesh in laparoscopic inguinal hernia repair

Background: The aim of our study was to compare chronic groin pain and quality of life (QOL) after laparoscopic lightweight (LW) and heavyweight (HW) mesh repair for groin hernia. Materials and Methods: One hundred and forty adult patients with uncomplicated inguinal hernia were randomised into HW mesh group or LW mesh group. Return to activity, chronic groin pain and recurrence rates were assessed. Short form-36 v2 health survey was used for QOL analysis. Results: One hundred and thirty-one completed follow-up of 3 months, 66 in HW mesh group and 65 in LW mesh group. Early post-operative convalescence was better in LW mesh group in terms of early return to walking (P = 0.01) and driving (P = 0.05). The incidence of early post-operative pain, chronic groin pain and QOL and recurrences were comparable. Conclusion: Outcomes following laparoscopic inguinal hernia repair using HW and LW mesh are comparable in the short-term as well as long-term

Autoacetylation of Purified Calreticulin Transacetylase Utilizing Acetoxycoumarin as the Acetyl Group Donor

Our earlier reports documented that calreticulin, a multifunctional Ca(2+)-binding protein in endoplasmic reticulum lumen, possessed protein acetyltransferase function termed Calreticulin Transacetylase (CRTAase). The autoacetylation of purified human placental CRTAase concomitant with the acetylation of receptor proteins by a model acetoxycoumarin, 7,8-Diacetoxy-4-methylcoumarin, was observed. Here, we have examined the autoacetylation property of CRTAase by immunoblotting and mass spectrometry. Ca(2+) was found to inhibit CRTAase activity. The inhibition of both autoacetylation of CRTAase as well as acetylation of the receptor protein was apparent when Ca(2+) was included in the reaction mixture as visualized by interaction with anti-acetyl lysine antibody. The acetylation of lysines residues: -48, -62, -64, -153, and -159 in N-domain and -206, -207, -209, and -238 in P-domain of CRTAase were located by high-performance liquid chromatography-electronspray ionization tandem mass spectrometry. Further, computer assisted protein structure modeling studies were undertaken to probe the effect of autoacetylation of CRTAase. Accordingly, the predicted CRTAase 3D model showed that all the loop regions of both N- and P-domain bear the acetylated lysines. Energy minimization of the acetylated residues revealed charge neutralization of lysines due to the N-epsilon-acetylation which may facilitate the interaction of CRTAase with the protein substrate and the subsequent transacetylase action
