A retrospective analysis of complications of laparoscopic left donor nephrectomy using the Kocak's modification of Clavien-Dindo system
Introduction: Kocak described a modification of Clavien-Dindo classification system (CDCS) for reporting procedure-related complications in laparoscopic donor nephrectomy (LDN). We used the Kocak modification in grading and reporting the severity of complications in patients who underwent LDN and in evaluating various parameters that predict them.
Methods: In all, 1430 patients who underwent left LDN from 2000 to 2016 were included in this study. All data was retrospectively collected and analyzed for complications occurring in the postoperative period. All complications were classified according to the four grades of Kocak-modified CDCS.
Results: 124 patients (8.6%) suffered a total of 235 postoperative complications. Most of the complications were Grade I and Grade II (Grade I: 79.5% [n = 187] and Grade II 16.2% [n = 38]), 2.5% of the complications were Grade III (n = 6) and Kocak Grade IVa complications occurred in three patients. There was one death (Grade IVb: 0.4%, overall mortality rate: 0.06%). The incidence of complications was significantly greater for male patients, those with body mass index ≥25 kg/m2, and if the operating surgeon had ≤ 1 year of experience in performing LDN surgery.
Conclusion: LDN is a safe procedure with low morbidity. The rate of complications is 8.6% and most of these complications are of low grade. The use of a standardized system for reporting the complications of LDN allows appropriate comparison between reported data

Dual Probe Sensors Using Atomically Precise Noble Metal Clusters
This article adds a new direction
to the functional capability
of protein-protected atomically precise gold clusters as sensors.
Counting on the extensively researched intense luminescence of these
clusters and considering the electron donating nature of select amino
acids, we introduce a dual probe sensor capable of sensing changes
in luminescence and conductivity, utilizing bovine serum albumin-protected
atomically precise gold clusters hosted on nanofibers. To this end,
we have also developed a hybrid nanofiber with a conducting core with
a porous dielectric shell. We show that clusters in combination with
nanofibers offer a highly selective and sensitive platform for the
detection of trace quantities of trinitrotoluene, both in solution
and in the vapor phase. In the solution phase, trinitrotoluene (TNT)
can be detected down to 1 ppt at room temperature, whereas in vapor
phase, 4.8 × 10<sup>9</sup> molecules of TNT can be sensed using
a 1 mm fiber. Although the development in electrospinning techniques
for fabricating nanofibers as sensors is quite substantial, a hybrid
fiber with the dual properties of conductivity and luminescence has
not been reported yet
