Background
Laparoscopic liver resection (LLR) has become an essential method for treating malignant liver tumors. Although the perioperative and oncologic outcomes of LLR in patients with hepatocellular carcinoma have been reported, there are few reports of LLR for intrahepatic cholangiocarcinoma (IHCC).Methods
Patients who underwent liver resection for T1 or T2 IHCC between March 2010 and March 2015 in Gyeongsang National University Hospital were enrolled. They were divided into open (n = 23) and laparoscopic (n = 14) approaches, and the perioperative and oncologic outcomes were compared.Results
The Pringle maneuver was less frequently used (p = 0.015) and estimated blood loss was lesser (p = 0.006) in the laparoscopic group. There were no significant differences in complication rate (p = 1.000), hospital stay (p = 0.371), tumor size (p = 0.159), lymph node metastasis (p = 0.127), and the number of retrieved lymph nodes (p = 0.553). The patients were followed up for a median of 21 months. The 3-year overall survival (OS) and recurrence-free survival (RFS) rates were 74.7 and 55.2 %, respectively. No differences were observed in the 3-year OS (75.7 vs 84.6 %, p = 0.672) and RFS (56.7 vs 76.9 %, p = 0.456) rates between the open and laparoscopic groups, even after the groups were divided into patients that received liver resection with or without lymph node dissection.Conclusion
LLR for IHCC is a treatment modality that should be considered as an option alongside open liver resection in selected patients.2.

Background
Patients with chronic kidney disease (CKD) have worse adverse cardiovascular outcomes after coronary artery bypass grafting (CABG). However, the adverse cardiovascular outcomes between off-pump coronary artery bypass grafting (OPCAB) versus on-pump coronary artery bypass grafting (ONCAB) in these patients have been a subject of debate.Methods
We undertook a comprehensive literature search of PubMed, Embase, and the Cochrane Library database to identify all relevant studies comparing techniques between OPCAB and ONCAB in CKD patients. We pooled the odds ratios (ORs) and hazard ratios (HRs) from individual studies and conducted heterogeneity, quality assessment, and publication bias analyses.Results
This meta-analysis includes 17 studies with 201,889 patients. In CKD patients, OPCAB was associated with significantly lower early mortality as compared to ONCAB (OR 0.88; 95% CI 0.82–0.93; p < 0.0001). OPCAB was associated with decreased risk of atrial fibrillation (OR 0.57; 95% CI 0.34–0.97; p = 0.04), cerebrovascular accident (OR 0.46; 95% CI 0.22–0.95; p = 0.04), blood transfusion (OR 0.20; 95% CI 0.08–0.49; p = 0.0005), pneumonia, prolonged ventilation, and shorter hospital stays. No difference was found regarding long-term survival (HR 1.08; 95% CI 0.86–1.36; p = 0.51) or myocardial infarction (OR 0.65; 95% CI 0.30–1.38; p = 0.26).Conclusions
Compared with ONCAB, OPCAB is associated with superior postoperative morbidity and the early mortality in CKD patients. Long-term survival is comparable between the two surgical revascularizations.3.

Purpose
The aim of the study was to externally validate the Zonal NePhRO Score (ZNS) published in 2014 as latest and superior nephrometry score in terms of prediction of perioperative complications and outcome of open partial nephrectomies (OPNs).Methods
We identified 200 consecutive patients who underwent OPN. Analysis of preoperative CT or MRI scans and retrospective analysis of the patients’ clinical records were performed. Tumour complexity was stratified according to the ZNS into three categories: low (4–6), moderate (7–9) and high (10–12) complexity. Predictors for perioperative complications and surgical parameters were identified using univariate and multivariate logistic regression.Results
Tumour complexity was graded in 19.8 % of the cases as low, in 50.3 % as moderate and in 29.9 % as high. In the multivariate analysis, ZNS was significantly associated with a higher complication rate (OR 1.25, 95 % CI 1.04–1.49, p = 0.014), longer ischaemia time (IT) (β = 1.19, 95 % CI 0.33–2.05, p = 0.007), postoperative drop of estimated glomerular filtration rate (eGFR) (β = ?1.86, 95 % CI ?3.71 to ?0.01, p = 0.049) and opening of the collecting system (CS) (OR 1.72, 95 % CI 1.40–2.10, p < 0.001). In addition, age and body mass index were identified as independent predictors for complications (OR 1.03, 95 % CI 1.00–1.06, p = 0.043 and OR 1.08, 95 % CI 1.00–1.15, p = 0.031).Conclusion
The present study is the first external validation of the ZNS as a predictor of perioperative complications in patients undergoing OPN. A higher ZNS score was associated with a longer IT, a higher rate of opening the CS and drop of eGFR.5.

Purpose
Decreased vitamin D levels have been associated with prostate cancer, but it is unclear whether this association is causal. A functional single-nucleotide polymorphism (SNP) in the group-specific component (GC) gene (T > G, rs2282679) has been associated with 25-hydroxy (25-OH) vitamin D and 1.25 dihydroxy (1.25-OH2) vitamin D levels.Methods
To examine the hypothesized inverse relationship between vitamin D status and prostate cancer, we studied the association between this SNP and prostate cancer outcome in the prospective PROCAGENE study comprising 702 prostate cancer patients with a median follow-up of 82 months.Results
GC rs2282679 genotypes were not associated with biochemical recurrence [hazard ratios (HR) 0.91, 95 % confidence interval (CI) 0.73–1.12; p = 0.36], development of metastases (HR 1.20, 95 % CI 0.88–1.63; p = 0.25) or overall survival (HR 1.10; 95 % CI 0.84–1.43; p = 0.50).Conclusions
A causal role of vitamin D status, as reflected by GC rs2282679 genotype, in disease progression and mortality in prostate cancer patients is unlikely.6.
Purpose
Insulin-like growth factor 1 (IGF1) gene single nucleotide polymorphism (rs5742612) has been associated with adolescent idiopathic scoliosis (AIS) in several studies with limited sample size and inconsistent outcomes. So we perform this meta-analysis to assess the precise association between IGF1 gene single nucleotide polymorphism (rs5742612) and AIS.Methods
We systematically searched Pubmed, Embase, Web of Science and Cochrane Library up to January 19, 2016 to obtain relevant studies using our research strategy. Four articles all belonging to case–control studies were included in our meta-analysis.Results
A total of four studies containing 763 cases and 559 controls satisfied the inclusion criteria after judgment by two reviewers. No significant associations were detected between IGF1 gene single nucleotide polymorphism (rs5742612) and AIS (T vs. C, OR = 1.10, 95 % CI 0.91–1.34, p = 0.32; TT vs. CC: OR = 1.28, 95 % CI 0.82–2.02, p = 0.28; TC vs. CC: OR = 1.29, 95 % CI 0.82–2.06, p = 0.27; TT/TC vs. CC: OR = 1.28, 95 % CI 0.83–1.98, p = 0.27; TT vs. TC/CC: OR = 1.06, 95 % CI 0.82–1.36, p = 0.66).Conclusions
IGF1 gene single nucleotide polymorphism (rs5742612) is not significant associated with susceptibility to AIS in either Asian or Caucasian populations. However, IGF1 gene rs5742612 may be associated with severity of AIS. Further studies with larger sample size and different population groups involving the relationship are required to confirm the potential association.7.

Backgrounds and objective
The technique of minimally invasive pancreatic surgeries has evolved rapidly, including minimally invasive pancreaticoduodenectomy (MIPD). However, controversy on safety and feasibility remains when comparing the MIPD with the open pancreaticoduodenectomy (OPD); therefore, we aimed to compare MIPD and OPD with a systemic review and meta-analysis.Methods
Multiple electronic databases were systematically searched to identify studies (up to February 2016) comparing MIPD with OPD. Intra-operative outcomes, oncologic data, postoperative complications and postoperative recovery were evaluated.Results
Twenty-two retrospective studies including 6120 patients (1018 MIPDs and 5102 OPDs) were included. MIPD was associated with a reduction in estimated blood loss (WMD ?312.00 ml, 95 % CI ?436.30 to ?187.70 ml, p < 0.001), transfusion rate (OR 0.41, 95 % CI 0.30–0.55, p < 0.001), wound infection (OR 0.37, 95 % CI 0.20–0.66, p < 0.001) and length of hospital stay (WMD ?3.57 days, 95 % CI ?5.17 to ?1.98 days, p < 0.001). Meanwhile, MIPD group has a higher R0 resection rate (OR 1.47, 95 % CI 1.18–1.82, p < 0.001) and more lymph nodes harvest (WMD 1.74, 95 % CI 1.03–2.45, p < 0.001). However, it had longer operation time (WMD 83.91 min, 95 % CI 36.60–131.21 min, p < 0.001). There were no significant differences between the two procedures in morbidities (p = 0.86), postoperative pancreatic fistula (p = 0.17), delayed gastric empting (p = 0.65), vascular resection (p = 0.68), reoperation (p = 0.33) and mortality (p = 0.90).Conclusions
MIPD can be a reasonable alternative to OPD with potential advantages. However, further large-volume, well-designed RCTs with extensive follow-ups are suggested to confirm and update the findings of our analysis.8.

Background
Although laparoscopic liver resection (LLR) is now considered a standard procedure in peripheral segments, there are few reports on laparoscopic segment 1 (Sg1) resection. The aim of this study was to assess both safety and feasibility of Sg1 LLR.Methods
From 2000 to 2014, all patients who underwent LLR were identified from a prospective database. Patients with resection of Sg1 (Sg1 group) were compared with those with resection of anteroinferior segments (AI group: segments 3, 4b, 5, 6) or posterosuperior segments (PS group: segments 4a, 7, 8), in terms of tumor characteristics, surgical treatment, and short-term outcomes.Results
There were 15, 151, and 67 patients in Sg1, AI, and PS groups. Tumor size and tumor number were similar between the three groups (p = 0.139, p = 0.102). Operative time was significantly shorter in Sg1 (150 min) and AI group (135 min) compared with PS group (180 min) (p = 0.021). Median blood loss was notably higher in PS group (140 ml) compared with Sg1 group (75 ml) and AI group (10 ml) (p = 0.001). No mortality was observed in all groups. Postoperative complication rate was 20.0 % with Sg1 group, 14.6 % with AI group, and 20.9 % with PS group (p = 0.060). The rate of major complication was significantly higher in Sg1 group (13.3 %) and PS group (11.9 %) compared with AI group (4.0 %) (p = 0.042). Resection margins were clear in all Sg1 and PS group patients, whereas two (1.3 %) patients in AI group had R1 margins (p = 0.586).Conclusion
The laparoscopic approach of isolated resection located in the caudate lobe is a feasible and curative surgical option in selected patients.9.

Introduction
The aim of this study was to examine the influence of an enhanced recovery programme (ERP) on outcomes of upper gastrointestinal (UGI) cancer surgery by means of propensity score-matched analysis.Methods
Three hundred consecutive patients diagnosed with UGI cancer were studied prospectively before and after the introduction of an ERP. Multiple regression models, including propensity scores, were developed to assess confounding variables associated with undergoing surgery, and the risk adjusted association between treatment and length of hospital stay (LOHS).Results
After regression for confounding factors, a cohort of 252 patients was available of whom 160 received ERP [median age 66 years (IQR 58–73), 119 male, 81 oesophageal, 79 gastric cancer] and 92 control [66 years (IQR 58–74), 74 male, 58 oesophageal, 34 gastric cancer]. ERP operative morbidity (Clavien–Dindo ≥3) and mortality were 13.8 and 3.1 % compared with 17.4 (p = 0.449) and 2.2 % (p = 0.658) in controls. Median ERP critical care and total LOS were 1 (IQR 0–1) and 13 (IQR 10–17) days, compared with 1 (IQR 1–2, p = 0.009) and 16 (IQR 13–26, p < 0.001) days. Multivariable analysis revealed ERP (HR 1.477, 95 % CI 1.084–2.013, p = 0.013), tumour location (HR 2.420, 95 % CI 1.624–3.606, p < 0.001), operative procedure (HR 1.143, 95 % CI 1.032–1.265, p = 0.010), and operative morbidity (HR 0.277, 95 % CI 0.179–0.429, p < 0.001) to be associated with LOHS.Conclusion
An ERP in UGI cancer surgery was feasible, safe, and effective.10.
Background
Individualised risk prediction is crucial if targeted pre-operative risk reduction strategies are to be deployed effectively. Radiologically determined sarcopenia has been shown to predict outcomes across a range of intra-abdominal pathologies. Access to pre-operative cross-sectional imaging has resulted in a number of studies investigating the predictive value of radiologically assessed sarcopenia over recent years. This systematic review and meta-analysis aimed to determine whether radiologically determined sarcopenia predicts post-operative morbidity and mortality following abdominal surgery.Method
CENTRAL, EMBASE and MEDLINE databases were searched using terms to capture the concept of radiologically assessed sarcopenia used to predict post-operative complications in abdominal surgery. Outcomes included 30 day post-operative morbidity and mortality, 1-, 3- and 5-year overall and disease-free survival and length of stay. Data were extracted and meta-analysed using either random or fixed effects model (Revman ® 5.3).Results
A total of 24 studies involving 5267 patients were included in the review. The presence of sarcopenia was associated with a significant increase in major post-operative complications (RR 1.61 95% CI 1.24–4.15 p = <0.00001) and 30-day mortality (RR 2.06 95% CI 1.02–4.17 p = 0.04). In addition, sarcopenia predicted 1-, 3- and 5-year survival (RR 1.61 95% CI 1.36–1.91 p = <0.0001, RR 1.45 95% CI 1.33–1.58 p = <0.0001, RR 1.25 95% CI 1.11–1.42 p = 0.0003, respectively) and 1- and 3-year disease-free survival (RR 1.30 95% CI 1.12–1.52 p = 0.0008).Conclusion
Peri-operative cross-sectional imaging may be utilised in order to predict those at risk of complications following abdominal surgery. These findings should be interpreted in the context of retrospectively collected data and no universal sarcopenic threshold. Targeted prehabilitation strategies aiming to reverse sarcopenia may benefit patients undergoing abdominal surgery.11.
Aim
To determine the prevalence of low back pain (LBP) among health sciences students and to identify the associated factors.Methods
Cross-sectional study was conducted among 1163 students from five health sciences colleges during the academic year 2016–2017. Self-administered questionnaire was conducted and included 4 sections: demographic characteristics, risk factors, Nordic musculoskeletal questionnaire and Oswestry disability questionnaire. Data were analyzed using SPSS.Results
Mean age was 20.74 ± (1.59 years). 70.9% of students were female. Lifetime prevalence of LBP was 56.6%, 12-month prevalence 48.8%, and point prevalence 21.2%. Dentistry students had highest lifetime prevalence of LBP (67.6%) with significant p value (<0.001). Male were found to have higher lifetime prevalence compared to female (p ≤ 0.001). Spending more than 10 h on computer or tablet was significantly associated with LBP (OR 2.19; 95% CI 1.30–3.70; p = 0.003). Feeling discomfort on bed was associated with LBP (OR 1.81; 95% CI 1.38–2.38; p ≤ 0.001). Uncomfortable college furniture was associated with LBP (OR 1.40; 95% CI 1.09–1.79; p = 0.008). Using heavy backpack was found to be associated with LBP (OR 1.49; 95% CI 1.01–2.03; p = 0.011). Most of students LBP (90.3%) found to cause minimal disability on Oswestry scale.Conclusion
This study has shown high prevalence of LBP among future healthcare provider. These risk factors should be well established to minimize the prevalence of LBP among future health sciences students. Dentistry students at higher risk of developing LBP compared to other students.12.

Background
Incisional hernias are one of the most common long-term complications associated with open abdominal surgery. The aim of this review and meta-analysis was to systematically assess laparoscopic versus open abdominal surgery as a general surgical strategy in all available indications in terms of incisional hernia occurrence.Methods
A systematic literature search was performed to identify randomized controlled trials comparing incisional hernia rates after laparoscopic versus open abdominal surgery in all indications. Random effects meta-analyses were calculated and presented as risk differences (RD) with their corresponding 95 % confidence intervals (CI).Results
24 trials (3490 patients) were included. Incisional hernias were significantly reduced in the laparoscopic group (RD ?0.06, 95 % CI [?0.09, ?0.03], p = 0.0002, I 2 = 75). The advantage of the laparoscopic procedure persisted in the subgroup of total-laparoscopic interventions (RD ?0.14, 95 % CI [?0.22, ?0.06], p = 0.001, I 2 = 87 %), whereas laparoscopically assisted procedures did not show a significant reduction of incisional hernias compared to open surgery (RD ?0.01, 95 % CI [?0.03, 0.01], p = 0.31, I 2 = 35 %). Wound infections were significantly reduced in the laparoscopic group (RD ?0.06, 95 % CI [?0.09, ?0.03], p < 0.0001, I 2 = 35 %); overall postoperative morbidity was comparable in both groups (RD ?0.06, 95 % CI [?0.13, 0.00], p = 0.06; I 2 = 64 %). Open abdominal surgery showed a significantly longer hospital stay compared to laparoscopy (RD ?1.92, 95 % CI [?2.67, ?1.17], p < 0.00001, I 2 = 87 %). At short-term follow-up, quality of life was in favor of laparoscopy.Conclusions
Incisional hernias are less frequent using the total-laparoscopic approach instead of open abdominal surgery. Whenever possible, the less traumatic access should be chosen.13.
Aim
To evaluate the efficacy and safety of PA21 versus sevelamer in dialysis patients.Methods
We searched Medline, Embase, Science Citation Index, Cochrane Central Register of Controlled Trials, and Clinical Trial Registries for randomized controlled trials comparing PA21 and sevelamer in dialysis patients.Results
Four studies were included. Compared with sevelamer group, PA21 needed fewer mean daily number of tablets (WMD, ? 7.97 pill; 95% CI, ? 11.28 to ? 4.65, p < 0.00001), developed fewer all adverse events (RR = 1.05; 95% CI, 1.00 to 1.11, p = 0.05), and developed fewer gastrointestinal adverse events (RR = 1.32; 95% CI, 1.15 to 1.53, p = 0.0001). There was no significant difference in serum phosphorus between two groups (WMD, ? 0.07 mmol/L; 95% CI, ? 0.15 to 0.02, p = 0.12). As for serum calcium, there was also no significant difference between two groups (WMD, 0.27 mmol/L; 95% CI, ? 0.63 to 1.17, p = 0.55).Conclusion
PA21 can effectively control serum phosphorus with lower pill burden and less side effects than sevelamer. PA21 might be another valuable choice for dialysis patients with hyperphosphatemia when patients are unable to tolerate sevelamer.14.
Purpose
To investigate the risk of renal hematoma (RHT) after shock wave lithotripsy (SWL) among patients on acetylsalicylic acid (ASA) or low-molecular-weight heparin (LMWH).Patients and methods
Retrospective analysis of 434 patients treated with SWL for nephrolithiasis and ureterolithiasis of the proximal ureter. Primary endpoint was detection of RHT by ultrasound the day after SWL. Secondary outcome variables included transfusion of erythrocyte concentrate(s), interventions, hospital readmission or death due to RHT within 30 days of SWL. Binary logistic regression analysis was used including a post hoc one-way analysis.Results
Of 434 patients, 33 (7.6%) and 67 (15.4%) patients were medicated with ASA and LMWH, respectively. RHT was detected in 20 of 434 (4.6%) patients. Of those, 3 (20%) were on ASA, 6 (35%) were on LMWH, 1 (5%) was on ASA and LMWH, and 10 (50%) had no anticoagulation. Univariate analysis showed a statistically significant higher risk for RHT among patients on ASA (p = 0.04) and LWMH (p = 0.02) with an untreated urinary tract infection (UTI) (p = 0.008) and history of cardiovascular disease (p = 0.028). On multivariate analysis, ASA medication, untreated UTI (OR 4.4, 95% CI 1.31–14.75, p = 0.016 and OR 5.79, 95% CI 1.65–20.32, p = 0.03) and a therapeutic dose of LMWH (OR 10.4, 95% CI 1.74–62.27, p = 0.01) were independent predictors for RHT.Conclusions
Before SWL, a patient risk profile should be evaluated. If feasible, LMWH in therapeutic dosing should be avoided, and ASA should be discontinued. UTI should be treated before SWL in any case.Trial registration

Purpose
The benefits of robotic-assisted radical cystectomy (RARC) are unclear, especially in patients with high-risk disease (pT3/T4). We evaluated pathological and postoperative outcomes of RARC versus open radical cystectomy (ORC) in these patients.Methods
We identified bladder cancer patients treated with RARC or ORC from January 2010–August 2014. Clinicodemographic factors were examined for potential confounding. Our primary outcome of interest was positive soft-tissue surgical margins (STSMs). Secondary outcomes included post-operative complications and length of stay (LOS). We used logistic regression to define the association between clinical factors with outcomes of interest, focusing on patients with locally advanced disease.Results
We identified 472 patients treated with ORC (407, 86.2 %) or RARC (65, 13.8 %) of which 215 (45.6 %) were high-risk cases based on advanced pathologic stage (pT3/4). RARC patients were more commonly men (96.9 vs. 73.2 %, p < 0.01), had better performance status (ECOG 0, 78.5 vs. 59.7 %, p = 0.031), and received less neoadjuvant chemotherapy (21.5 vs. 39.3 %, p = 0.006). Total (52.3 vs. 59.7 %, p = 0.26) and high-grade complication rates (13.8 vs. 19.7 %, p = 0.27) were similar, but median LOS was shorter after RARC (6 vs. 7 days, p < 0.01). On multivariate analysis, prior pelvic radiation (OR: 4.78, 95 % CI: 2.16–10.57), and advanced tumor stage (OR: 3.06, 95 % CI: 1.56–6.03) were independently associated with positive STSMs in high-risk patients but robotic surgical approach was not (OR: 0.81, 95 % CI: 0.29–2.30; p = 0.69).Conclusion
RARC had similar short-term postoperative outcomes compared to ORC and did not compromise oncological control in patients with extravesical disease.16.

Background
It remains uncertain whether a parathyroid gland (PG) that appears darkened or severely bruised but still has an attached vascular pedicle should be left in situ or taken out and auto-transplanted following total thyroidectomy. Our study aimed to examine the impact of discolored PGs (DPGs) on short- and long-term hypoparathyroidism.Methods
One hundred and three patients who underwent total thyroidectomy with 4 clearly identified PGs were analyzed. Location (superior/inferior) and color of each PG were recorded. Patients without DPG were grouped into I while those with 1–2 DPGs and ≥3 DPGs were grouped into II and III, respectively. Transient hypoparathyroidism meant adjusted Ca <2.00 mol/L 24 h after surgery and/or need for supplements. Protracted hypoparathyroidism meant a subnormal PTH at 4–6 weeks and/or supplements >6 weeks. Permanent hypoparathyroidism meant supplements ≥1 year.Results
Relative to I, group III had greater adjusted Ca drop at postoperative 1-h (p = 0.012), 24-h (p < 0.001) and lower day-1 PTH (p = 0.015). Having ≥3 DPGs (OR 14.00, 95 % CI 1.575–124.474, p = 0.018) was an independent factor of transient hypoparathyroidism. However, permanent hypoparathyroidism rate was higher than in group I than II (p = 0.019). Eight patients (25.8 %) in group I had undetectable day-1 PTH, while none in group III had undetectable day-1 PTH. Graves’ disease/toxic goiter (OR 15.166, 95 % CI 2.594–88.661, p = 0.003) and excised gland weight (OR 1.028, 95 % CI 1.010–1.046, p = 0.003) were independent factors of ≥3 DPGs.Conclusions
PG discoloration is associated with transient hypoparathyroidism while normal colored PG with seemingly adequate blood supply does not always imply functionally normal gland. These findings highlights the need for a real-time intraoperative method to assess PG viability.17.

Purpose
To examine the incidence of secondary primary malignancies in patients with renal cortical neoplasms.Methods
Between January 1989 and July 2010, 3647 patients underwent surgery at our institution for a renal cortical neoplasm and were followed through 2012. Occurrence of other malignancies was classified as antecedent, synchronous, or subsequent. All patients with antecedent malignancies (n = 498) and a randomly selected half of those with synchronous malignancies (n = 83) were excluded. The expected number of second primaries was calculated by multiplying Surveillance, Epidemiology, and End Results Program incidence rates of renal cortical neoplasms by person-years at risk within categories of age, sex, and year of diagnosis. The standardized incidence ratio (SIR) was calculated as observed cancers divided by expected incidence of the cancer, with approximation to the exact Poisson test used to obtain confidence intervals (CI) and p values.Results
Of 3066 patients with renal cortical neoplasms, 267 had a second primary cancer; the five most common in men were prostate, colorectal, bladder, lung, and non-Hodgkin’s lymphoma; the five most common in women were breast, colorectal, lung, endometrium, and thyroid. Men demonstrated higher than expected thyroid cancer rate (SIR 5.0; 95 % CI 1.83–10.88, p = 0.002), and women had higher than expected rates of stomach cancer (SIR 5.0; 95 % CI 1.61–11.67, p = 0.004) and thyroid cancer (SIR 4.62; 95 % CI 1.69–10.05, p = 0.003).Conclusions
The incidence of certain types of second malignancies may be higher in patients after diagnosis of renal cortical neoplasms compared to the general population. These observations can inform clinical follow-up in kidney cancer survivorship and future research studies.18.

Purpose
To investigate the association between preoperative neutrophil–lymphocyte ratio (NLR) and oncological outcomes in patients with localized prostate cancer (PCa) after radical prostatectomy (RP).Methods
We retrospectively reviewed the records of 1367 patients who underwent RP between November 2003 and April 2012. Patients who underwent a concurrent biopsy/procedure in other organs, had evidence of acute infection, or had systemic inflammatory disease were excluded. We divided the patients by NLR level and analyzed their perioperative outcomes. To determine NLR significance, we performed a multivariate logistic regression analysis of the pathological adverse outcomes and a Cox proportional hazard analysis of the biochemical recurrence (BCR), which was defined as a prostate-specific antigen level ≥0.2 ng/mL on two consecutive tests.Results
Among the 1367 patients, 158 (11.6 %) in the high-NLR (≥2.5) group had a higher biopsy Gleason score (p < 0.001), pathological Gleason score (p < 0.001), and pathological stage (p < 0.001) than patients in the low-NLR (<2.5) group (n = 1209, 88.4 %). Multivariate analysis revealed that high NLR was significantly correlated with adverse pathological outcomes of higher pathological stage (HR 1.688; 95 % CI 1.142–2.497; p = 0.009) and extracapsular extension (HR 1.698; 95 % CI 1.146–2.516; p = 0.008). Kaplan–Meier analysis showed significantly worse BCR-free survival (p < 0.001) in patients with a high NLR. A high NLR was a significant predictor of BCR after RP (HR 1.358; 95 % CI 1.008–1.829; p = 0.044).Conclusions
High NLR was significantly related to unfavorable clinicopathological outcomes and worse BCR-free survival. Further studies are needed to clarify the correlation between NLR and PCa.19.

Objective
Bariatric surgery has been shown to be the most effective method of achieving weight loss and alleviating obesity-related comorbidities. Yet, it is not being used equitably. This study seeks to identify if there is a disparity in payer status of patients undergoing bariatric surgery and what factors are associated with this disparity.Methods
We performed a case-control analysis of National Inpatient Sample. We identified adults with body mass index (BMI) greater than or equal to 25 kg/m2 who underwent bariatric surgery and matched them with overweight inpatient adult controls not undergoing surgery. The sample was analyzed using multivariate logistic regression.Results
We identified 132,342 cases, in which the majority had private insurance (72.8%). Bariatric patients were significantly more likely to be privately insured than any other payer status; Medicare- and Medicaid-covered patients accounted for a low percentage of cases (Medicare 5.1%, OR 0.33, 95% CI 0.29–0.37, p < 0.001; Medicaid 8.7%, OR 0.21, 95% CI 0.18–0.25, p < 0.001). Medicare (OR 1.54, 95% CI 1.33–1.78, p < 0.001) and Medicaid (OR 1.31, 95% CI 1.08–1.60, p = 0.007) patients undergoing bariatric surgery had an increased risk of complications compared to privately insured patients.Conclusions
Publicly insured patients are significantly less likely to undergo bariatric surgery. As a group, these patients experience higher rates of obesity and related complications and thus are most in need of bariatric surgery.20.
