Purpose
To evaluate the association between Wilms tumor histology at diagnosis and the change in Wilms' tumor volume during preoperative chemotherapy.Methods
We included all the 52 patients operated for Wilms tumor at 1988–2015, who had both pathology samples and either CT or MRI-images before and after preoperative chemotherapy, available for reevaluation.Results
The median tumor volume was 586?ml (IQR 323–903) at diagnosis. The median change in tumor volume was ? 68% (IQR ? 85 to ? 40, p?<?0.001) and the proportion of tumor necrosis 85% (IQR 24–97), after preoperative chemotherapy. There was a correlation between blastemal cell content in prechemotherapy cutting needle biopsy (CNB) sample and the reduction in tumor volume (Rho?=?? 0.452, p?=?0.002). High stromal and epithelial cell contents in CNB samples were associated with the lesser change in tumor volume (Rho?=?0.279, p? =0.053 and Rho?=?0.300, p?=?0.038 respectively). Reduction of tumor volume and the proportion of tumor necrosis after chemotherapy were associated (Rho?=?? 0.502, p?<?0.001). The actual viable tumor volume decreased in median by 97% (IQR 65–100), and the decrease could be seen in all cellular components. In three patients, the tumor volume increased more than 10% during the preoperative chemotherapy. Two of them had anaplastic tumor in the nephrectomy specimen.Conclusion
Wilms tumor total and viable tumor volumes were reduced by 68% and 97% with preoperative chemotherapy, respectively. High proportion of blastemal cells in CNB was associated with greatest decrease in Wilms tumor volume. Increase in tumor volume during preoperative chemotherapy may indicate anaplastic tumor and prolonging of preoperative therapy should be avoided.Type of study

Background
Understanding physician-level discrepancies is increasingly a target of US healthcare reform for the delivery of quality-focused patient care.Objective
To estimate the relative contributions of patient and surgeon characteristics to the variability in key outcomes after partial nephrectomy (PN).Design, setting, and participants
Retrospective review of 1461 patients undergoing PN performed by 19 surgeons between 2011 and 2016 at a tertiary care referral center.Intervention
PN for a renal mass.Outcomes measurements and statistical analysis
Hierarchical linear and logistic regression models were built to determine the percentage variability contributed by fixed patient and surgeon factors on peri- and postoperative outcomes. Residual between- and within-surgeon variability was calculated while adjusting for fixed factors.Results and limitations
On null hierarchical models, there was significant between-surgeon variability in operative time, estimated blood loss (EBL), ischemia time, excisional volume loss, length of stay, positive margins, Clavien complications, and 30-d readmission rate (all p < 0.001), but not chronic kidney disease upstaging (p = 0.47) or percentage preservation of glomerular filtration rate (p = 0.49). Patient factors explained 82% of the variability in excisional volume loss and 0–32% of the variability in the remainder of outcomes. Quantifiable surgeon factors explained modest amounts (10–40%) of variability in intraoperative outcomes, and noteworthy amounts of variability (90–100%) in margin rates and patient morbidity outcomes. Immeasurable surgeon factors explained the residual variability in operative time (27%), EBL (6%), and ischemia time (31%).Conclusions
There is significant between-surgeon variability in outcomes after PN, even after adjusting for patient characteristics. While renal functional outcomes are consistent across surgeons, measured and unmeasured surgeon factors account for 18–100% of variability of the remaining peri- and postoperative variables. With the increasing utilization of value-based medicine, this has important implications for the goal of optimizing patient care.Patient summary
We reviewed our institutional database on partial nephrectomy performed for renal cancer. We found significant variability between surgeons for key outcomes after the intervention, even after adjusting for patient characteristics. 相似文献3.

Background
This study compared perioperative outcomes between laparoscopic surgery (LS) and open surgery (OS) for pediatric inguinal hernia repair, using a national inpatient database.Methods
Using the Diagnosis Procedure Combination database in Japan, we compared duration of anesthesia, postoperative complications, recurrence, and metachronous hernia (MH) between LS and OS for children undergoing inguinal hernia repair from July 2010 to March 2016. We used multivariable logistic regression analysis for postoperative complications and Cox regression analysis for recurrence.Results
For 75,486 eligible patients (LS 20,186 vs. OS 55,300), the median follow-up was 815 (381–1350) days in LS and 1106 (576–1603) days in OS. The duration of anesthesia was significantly longer in LS than in OS for unilateral surgery (80 vs. 70 min, p < 0.001) but shorter for bilateral surgery (86 vs. 96 min, p < 0.001). LS had a lower proportion of MH than OS (0.3% vs. 3.4%, p < 0.001). There was no significant difference between LS and OS in complications (odds ratio: 0.55; 95% confidence interval: 0.22–1.38; p = 0.20) or recurrence (hazard ratio: 1.24; 95% confidence interval: 0.86–1.79; p = 0.89).Conclusions
LS patients had lower proportions of MH than OS patients. Complications and recurrence did not differ significantly between LS and OS.Type of study

Background
Partial nephrectomy (PN) is generally favored for cT1 tumors over radical nephrectomy (RN) when technically feasible. However, it can be unclear whether the additional risks of PN are worth the magnitude of renal function benefit.Objective
To develop preoperative tools to predict long-term estimated glomerular filtration rate (eGFR) beyond 30 d following PN and RN, separately.Design, setting, and participants
In this retrospective cohort study, patients who underwent RN or PN for a single nonmetastatic renal tumor between 1997 and 2014 at our institution were identified. Exclusion criteria were venous tumor thrombus and preoperative eGFR <15 ml/min/1.73 m2.Intervention
RN and PN.Outcome measurements and statistical analysis
Hierarchical generalized linear mixed-effect models with backward selection of candidate preoperative features were used to predict long-term eGFR following RN and PN, separately. Predictive ability was summarized using marginal , which ranges from 0 to 1, with higher values indicating increased predictive ability.Results and limitations
The analysis included 1152 patients (13 206 eGFR observations) who underwent RN and 1920 patients (18 652 eGFR observations) who underwent PN, with mean preoperative eGFRs of 66 ml/min/1.73 m2 (standard deviation [SD] = 18) and 72 ml/min/1.73 m2 (SD = 20), respectively. The model to predict eGFR after RN included age, diabetes, preoperative eGFR, preoperative proteinuria, tumor size, time from surgery, and an interaction between time from surgery and age (marginal ). The model to predict eGFR after PN included age, presence of a solitary kidney, diabetes, hypertension, preoperative eGFR, preoperative proteinuria, surgical approach, time from surgery, and interaction terms between time from surgery and age, diabetes, preoperative eGFR, and preoperative proteinuria (marginal ). Limitations include the lack of data on renal tumor complexity and the single-center design; generalizability needs to be confirmed in external cohorts.Conclusions
We developed preoperative tools to predict renal function outcomes following RN and PN. Pending validation, these tools should be helpful for patient counseling and clinical decision-making.Patient summary
We developed models to predict kidney function outcomes after partial and radical nephrectomy based on preoperative features. This should help clinicians during patient counseling and decision-making in the management of kidney tumors. 相似文献5.

Purpose
A meta-analysis including 11,900 cases showed that maternal gestational smoking was associated with increased risk of cryptorchidism. The aim of study was to investigate whether a hormone profile of cryptorchid boys and a supplementing histopathological evaluation of testicular biopsies could add detailed knowledge to the impact of maternal gestational smoking on pathogenesis of cryptorchidism.Methods
601 cryptorchid boys aged 4?months to 14?years old were included. Because normal hormones have a pronounced age dependency, we compared results from boys whose mothers had smoked heavily (> 10 cigarettes/day) during pregnancy with age matched cryptorchid controls of nonsmoking mothers (1:6). We studied: birthweight, germ-cell number/tubular cross section, frequency of germ cells positive for placental-like alkaline phosphatase (PLAP), gonadotropins and inhibin-B.Results
501 boys were sons of nonsmokers, 72 boys of intermittent smokers and 28 boys of heavy smokers. 39%, 44% and 61% respectively had bilateral cryptorchidism. Compared to age-matched cryptorchid controls of nonsmoking mothers, sons of heavy smokers had lower birthweight (p?=?0.006), germ-cell number/tubular cross section (p?=?0.009), frequency of germ cells positive for PLAP (p?=?0.037) and inhibin-B (p?=?0.042).Conclusions
All findings could be associated with placental dysfunction with altered human chorionic gonadotropin production well described in women smoking during pregnancy.Type of study

Background/Purpose
The Abernethy malformation (AM) is a congenital venous malformation in which the splanchnic venous return bypasses the liver and drains directly into the systemic circulation. This deprives the liver of hepatotrophic growth factors and allows metabolic products of digestion to enter the systemic veins without the benefit of passing through the liver. The histologic features of liver biopsies in children with an AM were reviewed.Methods
A retrospective review of liver biopsies in patients with AM between 1997 and 2017 was performed. Patients were divided into two groups for comparison of histologic features: presence (M +) or absence (M ?) of a coexistent liver mass on imaging. Biopsies were reviewed by a pediatric pathologist. Chi-square test was used for statistical analysis between groups. Significance was assigned to p values < 0.05.Results
Eighteen liver biopsies were reviewed. Masses were present in only 6 patients who had a liver biopsy. Masses were observed with similar frequencies in either type of the Abernethy malformation (I or II). Nine of 12?M ? patients and 3/6?M + patients had the type I AM. Histologically, all patients were noted to have small or absent portal veins. Isolated capillaries were seen more frequently in patients with a known liver mass (p?=?0.045), while crowding of portal tracts was more commonly seen in patients without a liver mass (p?=?0.019).Conclusion
Liver biopsies in patients with AM demonstrate abnormal vascular and parenchymal histologic features. Livers with coexistent masses were more commonly found to have features suggesting an increased dependence on arterial blood supply.Level of evidence

Purpose
The low perioperative mortality rate in pediatric surgery precludes effective analysis of mortality at individual institutions. Therefore, analysis of multi-institutional data is essential to determine any patterns of perioperative death in children. The aim of this study was to determine diagnoses associated with 24-hour and 30-day perioperative mortality.Methods
A retrospective review of the 2012-2015 Pediatric Participant Use Data File (PUF) was performed. Statistical comparisons were made between survivors and nonsurvivors and between those with 24-hour and 30-day mortality using Fischer’s exact tests. P-values ≤ 0.05 were considered significant.Results
103,444 patients who underwent a pediatric surgical operation were evaluated. There were 732 deaths with a 30-day perioperative mortality of 0.7% (732/103,444). Necrotizing enterocolitis (NEC) was the diagnosis associated with the highest 30-day perioperative mortality (175/901, 19%). A significantly higher proportion NEC deaths occurred in the first 24 hours (67% (118/175) vs 33% (57/175) 30 day mortality, p < 0.001). Compared to patients who survived following operation for NEC, those who died were statistically more likely to require inotropic support (56% vs. 15%, p < 0.001), be diagnosed with sepsis (52% vs. 22%, p < 0.001), and undergo blood transfusion within 48 hours of operation (49% vs. 34%, p < 0.001).Conclusion
Although the overall pediatric surgical operative mortality rate is low, the largest proportion of perioperative deaths occur secondary to NEC. Based on the high immediate mortality, optimization of operative care for septic patients with NEC should be targeted.Type of Study

Background/Purpose
Massive transfusion protocols (MTPs) are considered valuable in pediatric trauma. Important questions regarding the survival benefit and optimal blood component ratio remain unknown.Methods
The study time frame was January 2007 through December 2013 five Level I Pediatric Trauma Centers reviewed all trauma activations involving children ≤ 18?years of age. Included were patients who either had the institutional MTP or received > 20?mL/kg or?>?2?units packed red blood cells (PRBCs).Results
110/202 qualified for inclusion. Median age was 5.9?years (3.0–11.4). 73% survived to discharge; median hospitalization was 10 (3.1–22.8) days. Survival did not vary by arrival hemoglobin (Hgb), gender or age. Partial prothrombin time (PTT), INR, GCS and injury severity score (ISS) significantly differed for nonsurvivors (all p?<?0.05). Logistic regression found increased mortality (OR 3.08 (1.10–8.57), 95% CI; p?=?0.031) per unit increase over a 1:1 ratio of pRBC:FFP.Conclusion
In pediatric trauma pRBC:FFP ratio of 1:1 was associated with the highest survival of severely injured children receiving massive transfusion. Ratios 2:1 or ≥ 3:1 were associated with significantly increased risk of death. These data support a higher proportion of plasma products for pediatric trauma patients requiring massive transfusion.Level of evidence

Purpose
To investigate whether serial measurements of fecal calprotectin concentrations enable us to identify infants who will develop NEC prior to development of symptoms.Methods
Prospective matched case–control study including 100 high-risk neonates. High risk includes 1) gestational age (GA) ≤ 30?weeks, 2) birth-weight (BW) ≤ 1000?g, 3) GA 30–32?weeks and BW ≤ 1250?g, 4) born from a mother who received indomethacin for tocolysis. We matched every NEC subject with three controls for birth weight and gestational age. Fecal calprotectin was measured twice a week from day one until five weeks after birth or until NEC development. We analyzed differences in fecal calprotectin between NEC subjects and controls in the week preceding NEC onset and course of fecal calprotectin within subjects who developed NEC.Results
Of 100 included patients, ten (median GA 27.5?weeks [24.6–29.4], BW 1010?g [775–1630]) developed NEC. The median calprotectin concentration in all samples combined was 332?μg/g [< 40–8230] μg/g feces. There were no differences between NEC subjects and controls, with a wide variation in both groups. In NEC subjects, there was no intraindividual rise in calprotectin before clinical symptoms occurred.Conclusions
There are high concentrations and wide interindividual variations in calprotectin in preterm infants during the first weeks of life. Wide intraindividual variation further precludes the serial use of fecal calprotectin in the early detection or prediction of NEC in high risk infants.Level of Evidence

Background/purpose
Computed tomography (CT) derived Haller Index (HI) remains the standard for quantifying severity in patient with pectus excavatum (PE). Optical scanning described in literature reports optimistic results and new indices that correlate with HI. This study assessed the feasibility of a handheld White Light Scanner (WLS) to obtain 3D measurements and indices of PE deformity.Methods
From April 2015–April 2017, WLS scanning was conducted by orthotists during clinical visits. Included were children with PE up to 18?years. Analysis assessed correlation of a WLS-derived severity index, Hebal-Malas Index (HMI), with physician measured PE Depth (PED), and CT-derived HI.Results
Of 195 participants, 185(94%) patients with PE were scanned and 127(69%) had complete WLS data. For 88 patients undergoing monitoring, HMI correlated with PED (r?=?0.42, p?=?0.004). For 39 patients with pre-operative CT, HMI demonstrated strong correlation with HI (r?=?0.87, p < 0.0001).Conclusions
WLS demonstrated high feasibility of scanning PE. WLS-derived HMI best correlates with HI for patients with severe pectus deformity. Our current data is suggestive that WLS is best applied for severe deformities and yet to be established for milder deformities. Future yearly WLS will provide data on deformity progression and surgical therapy.Level of Evidence

Background
Although serial transverse enteroplasty (STEP) improves function of dilated short bowel, a significant proportion of patients require repeat surgery. To address underlying reasons for unsuccessful STEP, we compared small intestinal mucosal characteristics between initial and repeat STEP procedures in children with short bowel syndrome (SBS).Methods
Fifteen SBS children, who underwent 13 first and 7 repeat STEP procedures with full thickness small bowel samples at median age 1.5 years (IQR 0.7–3.7) were included. The specimens were analyzed histologically for mucosal morphology, inflammation and muscular thickness. Mucosal proliferation and apoptosis was analyzed with MIB1 and Tunel immunohistochemistry.Results
Median small bowel length increased 42% by initial STEP and 13% by repeat STEP (p = 0.05), while enteral caloric intake increased from 6% to 36% (p = 0.07) during 14 (12-42) months between the procedures. Abnormal mucosal inflammation was frequently observed both at initial (69%) and additional STEP (86%, p = 0.52) surgery. Villus height, crypt depth, enterocyte proliferation and apoptosis as well as muscular thickness were comparable at first and repeat STEP (p > 0.05 for all). Patients, who required repeat STEP tended to be younger (p = 0.057) with less apoptotic crypt cells (p = 0.031) at first STEP. Absence of ileocecal valve associated with increased intraepithelial leukocyte count and reduced crypt cell proliferation index (p < 0.05 for both).Conclusions
No adaptive mucosal hyperplasia or muscular alterations occurred between first and repeat STEP. Persistent inflammation and lacking mucosal growth may contribute to continuing bowel dysfunction in SBS children, who require repeat STEP procedure, especially after removal of the ileocecal valve.Level of evidence

Introduction and objective
One of the inherent features of kidney tumours is the capacity to spread inside the venous system as tumour thrombi. The aim of this study was to assess in patients with stage pT3apN0cM0 kidney cancer whether venous tumour involvement influenced tumour recurrence.Materials and methods
A retrospective analysis of patients with stage pT3apN0cM0 kidney cancer treated with radical nephrectomy between 1990-2015. Univariate and multivariate Cox regression analysis to identify predictive variables and independent predictive variables relating to recurrence.Results
The results of 153 patients were studied. The median follow-up was 82 (IQR 36-117) months. Recurrence-free survival at 5 years was 58.9% with a median of 97 (95% CI 49.9-144.1) months. Seventy-seven (50.3%) patients recurred. Seventy cases 70 (90.9%) had distant metastases, 17 (14.2%) of these patients had local recurrence in the bed of nephrectomy. Tumour necrosis (p = .0001), and microvascular invasion (p = .001) were identified as independent predictors of tumour recurrence in the multivariable analysis.Conclusions
In our series, after multivariable analysis, venous tumour extension was not related to recurrence. Tumour necrosis and microvascular infiltration did behave as independent predictive factors of tumour recurrence. 相似文献14.
Surgical management of follicular thyroid carcinoma in children and adolescents: A study of 30 cases

Background/Purpose
The purpose of the study is to describe the anatomoclinical, diagnostic, therapeutic and prognostic aspects of pediatric follicular thyroid carcinoma (FTC) in order to choose the best therapeutic strategy.Methods
Our study includes patients ≤ 18?years old surgically treated for FTC in four Italian Pediatric Surgery Centers from January 2000 to March 2017. The collected data were compared with those of 132 patients matched for age with a histological diagnosis of papillary thyroid carcinoma (PTC) surgically treated in the same institutions during the same period and with the data of patients diagnosed with FTC found in the literature; p-values < 0.05 were considered significant.Results
21 (70%) of the 30 patients with a histological diagnosis of FTC underwent hemithyroidectomy while 9 (30%) underwent total thyroidectomy. 11 (55%) out of 21 patients were subjected to a completion of thyroidectomy. All patients are alive (OS?=?100%) without recurrence or relapse of the disease. Compared with PTC, FTC is significant for capsule infiltration (p?<?0.0001), vascular invasion (p?=?0.0014) and T-stage T3-T4 (p?=?0.013). However, multifocality (p?<?0.001), extrathyroid extension (p?<?0.0001) and lymph node metastasis (p?<?0.0001) are more evident in PTC.Conclusion
The conservative approach seems to be a valid surgical treatment for pediatric patients diagnosed with MI-FTC. For patients with wide vascular invasion and/or a tumor > 4?cm, especially with high after-surgery Tg rate, a completion of thyroidectomy is recommended. In patients with multifocal neoplasia, and/or tumor size ≥ 4?cm, and/or extrathyroid extension, and/or lymph node metastasis, and/or distant metastasis, total thyroidectomy followed by radioiodine therapy is generally indicated.Levels of Evidence

Background/purpose
Anorectal malformation (ARM) is a common condition. Owing to scarcity of pediatric surgery services in Uganda, however, relatively little is known about this condition.Methods
This was a retrospective review of medical records of all patients admitted to Mbarara Regional Referral Hospital (MRRH) from January 2014 to May 2016. MRRH serves 3–8 million people in southwest Uganda. We also enrolled patients prospectively from June 2016 to December 2016.Results
78 patients were enrolled in the study. 63.38% had delayed diagnosis (presenting > 48?h after birth), and most of these were self-referrals from home. The most common malformation was a vestibular fistula. Associated congenital anomalies were seen in 20% of patients, and this was associated with increased mortality. These anomalies included limb, eye, ear and genitourinary anomalies as well as ventricular septal defects, patent ductus arteriosus, spina bifida and tracheoesophageal fistula. Posterior sagittal anorectoplasty (PSARP) was the definitive surgery used. It was performed in 58.97% of the patients. Median age of patients who underwent PSARP was 11?months. 73.91% of PSARP patients had their colostomies closed and 62.5% of these who were?≥ 3 years old had good continence outcomes. Overall mortality rate was 8.97%.Conclusion
The majority of patients are diagnosed late. Vestibular fistula is the overall most common type of ARM. In males, however, rectourethral fistula is the most common type. Definitive surgery at MRRH is performed late. Continence outcomes are good and comparable to other countries with more resources.Level of evidence

Background
Evidence-based guidelines recommend ultrasound (US) over computed tomography (CT) as the primary imaging modality for suspected pediatric appendicitis. Continued high rates of CT use may result in significant unnecessary radiation exposure in children. The purpose of this study was to evaluate variables associated with preoperative CT use in pediatric appendectomy patients.Methods
A retrospective cohort study of pediatric patients who underwent appendectomy for acute appendicitis in 2015–2016 at National Surgical Quality Improvement Program for Pediatrics (NSQIP-P) hospitals was conducted. Pediatric (< 18?years old) patients who underwent appendectomy for acute appendicitis in an NSQIP-P hospital from 2015 to 2016 were included. Patients were excluded if they underwent interval or incidental appendectomy or did not have a final diagnosis of appendicitis. Variables associated with imaging evaluation, including age, body mass index (BMI), race/ethnicity, gender and hospital of presentation (NSQIP-P vs. non-NSQIP-P hospital) were evaluated. The primary outcome was receipt of preoperative CT. Secondary outcomes include reimaging practices and trends over time.Results
22,333 children underwent appendectomies, of which almost all were imaged preoperatively (96.5%) and 36% of whom presented initially to a non-NSQIP-P hospital. Overall, US only was the most common imaging modality (52%), followed by CT only (27%), US + CT (16%), no imaging (3%), MRI +/? CT/US (1%) and MRI only (< 1%). On regression, older age (> 11?years), obesity (BMI > 95th percentile for age), and female gender were associated with increased odds of receiving a CT scan. However, initial presentation to a non-NSQIP-P hospital was the strongest predictor of CT use (OR 9.4, 95% CI 8.1–10.8). Reimaging after transfer was common, especially after US and MRI at a non-NSQIP-P hospital. CT use decreased between 2015 and 2016 in non-NSQIP-P hospitals but remained the same (25%) in NSQIP-P facilities.Conclusions
Though patient characteristics were associated with different imaging practices, presentation at a referral, nonchildren's hospital is the strongest predictor of CT use in children with appendicitis. NSQIP-P hospitals frequently reimage transferred patients and have not reduced their CT use. Novel strategies are required for all hospital types in order to sustain reduction in CT use and mitigate unnecessary imaging.Level of Evidence

Background
We report our experience with the Minimally Invasive Chevron Akin (MICA) technique for correcting hallux valgus, and evaluate its effectiveness and associated complications.Methods
Case series of 13 feet with mild to moderate symptomatic hallux valgus treated surgically from July 2013 to December 2014, with at least 48-months follow-up. Patients were assessed pre-operatively and post-operatively with radiographical measurements (Hallux Valgus Angle (HVA) and Intermetatarsal Angle (IMA)) and clinical scores (American Orthopaedic Foot and Ankle Society (AOFAS), 36-Item Short Form Health Survery (SF-36), Visual Analog Scale (VAS)).Results
Mean HVA and IMA decreased from 30.4° and 13.9°–10.9° and 10.2° respectively (p < 0.05). The mean AOFAS score improved from an average of 59.0–93.7 (p < 0.05). All patients reported a VAS score of 0 post-operatively, and the 4 SF-36 domains improved significantly (p < 0.05).Conclusions
The MICA technique is a safe and effective method in the surgical correction of mild to moderate hallux valgus deformity, and continued use is justified. 相似文献18.

Some studies suggest that gonadotropin-releasing hormone (GnRH) agonists are associated with higher risk of adverse events than antiandrogens (AAs) monotherapy. However, it has been unclear whether this is due to indication bias.Objective
To investigate rates of change in comorbidity for men on GnRH agonists versus AA monotherapy in a population-based register study.Design, setting, and participants
Men with advanced nonmetastatic prostate cancer (PCa) who received primary AA (n = 2078) or GnRH agonists (n = 4878) and age- and area-matched PCa-free men were selected from Prostate Cancer Database Sweden 3.0. Increases in comorbidity were measured using the Charlson Comorbidity Index (CCI), from 5 yr before through to 5 yr after starting androgen deprivation therapy (ADT).Outcome measures and statistical methods
Multivariable linear regression was used to determine differences in excess rate of CCI change before and after ADT initiation. Risk of any incremental change in CCI following ADT was assessed using multivariable Cox regression analyses.Results and limitations
Men on GnRH agonists experienced a greater difference in excess rate of CCI change after starting ADT than men on AA monotherapy (5.6% per yr, p < 0.001). Risk of any new CCI change after ADT was greater for GnRH agonists than for AA (hazard ratio, 1.32; 95% confidence interval, 1.20–1.44).Conclusions
Impact on comorbidity was lower for men on AA monotherapy than for men on GnRH agonists. Our results should be confirmed through randomised trials of effectiveness and adverse effects, comparing AA monotherapy and GnRH agonists in men with advanced nonmetastatic PCa who are unsuitable for curative treatment.Patient summary
Hormone therapies for advanced prostate cancer can increase the risk of other diseases (eg, heart disease, diabetes). This study compared two common forms of hormone therapy and found that the risk of another serious disease was higher for those on gonadotropin-releasing hormone agonists than for those on antiandrogen monotherapy. 相似文献19.

Objectives
Abdominal wall thickness (AWT) is a key measurement when placing or replacing low profile gastrostomy devices. This measurement varies, depending on nutritional status and body habitus. We developed a mathematical model to estimate AWT using a compendium of body measurements.Methods
Ultrasonography was used to measure AWT at the initial gastrostomy site in subjects aged 22?days to 24?years old. Other body measurements (height, weight, waist circumference and distance from xiphisternum to pubis) were also obtained. Multiple linear regression was used to develop two separate models using age of 2?years to separate the groups. For analysis, AWT is log transformed.Results
Data from 97 subjects were used for analysis.The final model for those ≤ 24?months old is the following:ln(Estimated AWT)?=?? 1.255?+?0.082*(1 if age 3–24?months, 0 if <3?months)?+?0.022*(waist circumference in cm).The final model for those > 24 months old is the following:ln(Estimated AWT)?=?? 1.335?+?0.271*(1 if age >84?months, 0 if 24–84 months)?+?0.082*(BMI)Conclusion
This model to estimate AWT is useful for determining the length of a gastrostomy device at initial placement and with subsequent changes. More data are needed to refine and further validate the model.Level of evidence
Level IV, study of prognostic test. 相似文献20.
