Clinical significance of risk stratification of esophageal squamous cell carcinoma after neoadjuvant chemoradiation and surgery

ObjectiveNowadays, there were few studies reporting the risk stratification of patients with esophageal squamous cell carcinoma (ESCC) after neoadjuvant chemoradiation (NCRT) and surgery. We aimed to establish a simple risk stratification to help postoperative detection and adjuvant treatment.MethodsWe included 146 patients with locally advanced ESCC who received NCRT followed by esophagectomy. The impacts of clinicopathological factors on overall survival (OS) and disease-free survival (DFS) were analyzed. The recurrence site, time, and frequency were recorded as well.ResultsThe median follow-up was 53 months. The pathological complete respond (pCR) group demonstrated better 5-year OS and DFS (78.6% and 77.0%) than the non-pCR group (44.8% and 35.2%, all P < 0.005). Multivariate analysis for the non-pCR group revealed perineural invasion (PNI) (HR:2.296, P = 0.013) and ypTNM stage (I/II vs III/IV) (HR:1.972, P = 0.046) were considered as independent unfavorable factors affecting OS, while PNI (HR:1.866, P = 0.045) and lymph vessel invasion (LVI) (HR:3.370, P < 0.001) were considered as independent adverse factors for DFS. Based on clinicopathological factors (including pCR, ypTNM stage, PNI, LVI), patients were divided into the low-risk (pCR), mediate-risk (non-pCR without PNI, LVI, stage III/IV), high-risk (non-pCR with one factor of PNI, LVI or stage III/IV (n = 45)), highest risk (non-pCR with two or more factors of PNI, LVI or stage III/IV) groups. The corresponding 5-year OS rates were 78.6%, 60.4%, 49.6%, 18.6%, respectively (P < 0.005) and 5-year DFS rates were 77.0%, 46.9%, 41.1%, 12.1%, respectively (P < 0.005). Adjuvant chemotherapy may improve survival in high or highest risk groups of patients with low prognostic nutritional index (< 49).ConclusionsA novel risk stratification based on clinicopathological factors may be conducive to postoperative surveillance and guide adjuvant chemotherapy.     

The Association of Platelet Count with Clinicopathological Significance and Prognosis in Renal Cell Carcinoma: A Systematic Review and Meta-Analysis

ObjectiveElevated platelet count (PC), a measure of systemic inflammatory response, is inconsistently reported to be associated with poor prognosis in patients with renal cell carcinoma (RCC). We conducted a systematic review and meta-analysis to clarify the significance of PC in RCC prognosis.MethodsPubMed, Embase, and Web of Science databases were searched to identify eligible studies to evaluate the associations of PC with patient survival and clinicopathological features of RCC.ResultsWe analyzed 25 studies including 11,458 patients in the meta-analysis and categorized the included articles into three groups based on RCC stage. An elevated PC level was associated with poor overall survival (OS, hazard ratio [HR] 2.24, 95% confidence interval [CI] 1.87-2.67, P<0.001) and cancer-specific survival (CSS, HR 2.59, 95% CI 1.92-3.48, P<0.001) when all stages were examined together; with poor CSS (HR 5.09, 95% CI 2.41-10.73, P<0.001) and recurrence-free survival (HR 6.68, 95% CI 3.35-13.34, P<0.001) for localized RCC; with poor OS (HR 2.00, 95% CI 1.75-2.28, P<0.001) for metastatic RCC; and with poor OS (HR 2.05, 95% CI 1.04-4.03, P = 0.038), CSS (HR 3.38, 95% CI 1.86-6.15, P<0.001), and PFS (HR 2.97, 95% CI 1.47-6.00, P = 0.002) for clear cell RCC. Furthermore, an elevated PC level was significantly associated with TNM stage (OR 3.11, 95% CI 1.59-6.06, P = 0.001), pathological T stage (OR 3.13, 95% CI 2.60-3.77, P<0.001), lymph node metastasis (OR 4.01, 95% CI 2.99-5.37, P<0.001), distant metastasis (OR 3.85, 95% CI 2.46-6.04, P<0.001), Fuhrman grade (OR 3.70, 95% CI 3.00-4.56, P<0.001), tumor size (OR 4.69, 95% CI 2.78-7.91, P<0.001) and Eastern Cooperative Oncology Group score (OR 5.50, 95% CI 3.26-9.28, P<0.001).ConclusionAn elevated PC level implied poor prognosis in patients with RCC and could serve as a readily available biomarker for managing this disease.     

Gender Differences in Questions Asked in an Online Preoperative Patient Education Program

BackgroundAlthough osteoarthritis more commonly affects women than men, women are 3 times less likely to undergo hip or knee replacement surgery compared with men. Disparity in the appropriate utilization of surgery between men and women is a complex subject that must take into account the willingness of a patient to proceed with the operation. Adequately addressing patient concerns before surgery may influence such willingness.ObjectiveWe examined if a gender difference can be identified in the frequency and types of questions submitted by patients scheduled for total hip or total knee arthroplasty.MethodsPatients completed an online interactive preoperative educational program and a database was created containing deidentified information on surgical procedure, sex, year of birth, and any questions that were submitted. Data were also available regarding the total number of patients issued the program, the number of patients who started the program, and the number of patients who completed the program. The results were analyzed by Wilcoxon rank sum test. P values ≤0.05 were considered statistically significant.ResultsAmong the 2770 women and 1708 men included in the study, 935 (34%) and 462 (27%) asked at least 1 question, respectively. Compared with men, women asked a significantly greater number of questions overall (P < 0.001). Women also asked a significantly greater number of questions in the categories Your Condition (P = 0.031), Your Procedure (P < 0.001), and Risks and Benefits (P < 0.001).ConclusionsGender differences in concerns and physicians' ability to adequately address these concerns may contribute to disparity in use of hip and knee replacement surgery between men and women. Effective preoperative counseling for women may require additional resources to address their higher level of questions.     

Interrelations and associations of serum levels of steroids and pituitary hormones with markers of insulin resistance,inflammatory activity,and renal function in men and women aged >70 years in an 8-year longitudinal study of opposite-sex twins

Background: The physiological serum levels of steroids and pituitary hormones in older men and women have been sparsely reported in the literature.Objectives: The aims of this study were to investigate the normal variation and sex differences in steroids and pituitary hormones in those aged >70 years, and to study the interrelation between these hormones and indicators of the metabolic syndrome, inflammatory activity, and renal function.Methods: The investigation comprised a population-based sample of pairs of white opposite-sex twins from the Swedish Twin Registry. At baseline in 1996 and at the 8-year follow-uup in 2004, serum levels of progesterone, cortisol, testosterone, estradiol, follicle-stimulating hormone, luteinizing hormone, prolactin, creatinine, C-reactive protein (CRP), and urea were analyzed. Serum levels of insulin and cystatin were analyzed only at the follow-up.Results: The study sample included 219 men and 183 women aged 71 to 80 years (mean [SD], 74.5 [2.5] years) at baseline in 1996, and 127 men and 135 women at follow-uup in 2004. At baseline, in both men and women, the variation of progesterone in serum was positively correlated with that of estradiol (men: r = 0.226, P < 0.01; women: r = 0.115, P = NS), testosterone (men: r = 0.178, P < 0.01; women: r = 0.315, P < 0.001), and cortisol (men: r = 0.314, P < 0.001; women: r = 0.296, P < 0.001). The values of progesterone and other steroid hormones were associated with markers of insulin resistance (iie, insulin, waist circumference), inflammatory activity (ie, CRP) for progesterone (men: r = 0.267, P < 0.001; women: r = 0.150, P < 0.05), and renal function (ie, creatinine) for progesterone (men: r = 0.424, P < 0.001; women: r = 0.212, P < 0.01). Estradiol and prolactin were associated with insulin resistance, inflammation, and renal function. Furthermore, progesterone was associated with prolactin (men: r = 0.275, P < 0.001; women: r = 0.172, P < 0.05).. Among both men and women, there was a strong correlation between testosterone and estradiol (men: r = 0.753, P < 0.001; women: r = 0.526, P < 0.001); in women, there was also a link between testosterone and cortisol at follow-up (r = 0.340, P < 0.01). For progesterone, there was a significant correlation between the values of the co-twins (in 1996: r = 0.16, P < 0.05; in 2004: r = 0.45, P < 0.001). Higher serum levels of progesterone (2.0 [0.7] nmol/L in men and 1.7 [0.8] nmol/L in women) and prolactin (6 [5] μg/L in men and 8 [10] μg/L in women) were found among those who were deceased at follow-up compared with survivors (progesterone: 1.8 [0.5] nmol/L in men and 1.4 [0.6] nmol/L in women, P < 0.01; prolactin: 4 [3] μg/L in men and 5 [2] μg/L in women, P < 0.001).Conclusions: In this study of opposite-sex Swedish twins aged >70 years, there was a sex difference in the serum levels of steroids and pituitary hormones between men and women. Progesterone and other steroid hormones were associated with markers of insulin resistance, inflammatory activity, and renal function. Progesterone and prolactin levels were associated with increased risk of mortality in this sample.     

Gender-specific differences in bladder cancer: A retrospective analysis

Background: A higher incidence of bladder cancer has been reported in men compared with women. Clinical gender differences have been observed but are less well described.Objective: This retrospective analysis further examines clinical differences in the development and manifestation of bladder cancer between men and women.Methods: Consecutive male and female patients with bladder cancer treated between 1969 and 1997 at a single center (University Hospital of Innsbruck, Innsbruck, Austria) were included in the study. Patient characteristics regarding age, tumor classification, localization, and recurrence were compared between male and female patients. Statistical analysis was conducted using the t test, the χ² test, and the Kaplan-Meier method, with the log-rank test for subgroup analysis.Results: In the 1269 patients (876 men, 393 women) who were examined, 1744 tumors were found. The male-to-female bladder cancer incidence ratio was 2.2:1. Tumors were diagnosed at a significantly younger age in men than in women (mean age: 62 years vs 67 years, respectively; P < 0.001). No difference in the histology of tumors was observed between the sexes. Muscle-invasive tumors more frequently occurred in men than in women (39.8% vs 34.5%; P = NS). In men compared with women, primary tumors were more aggressive (grade 2, 36.6% vs 28.2%; P < 0.001) and tumor recurrences were more invasive (59.0% vs 57.8%; P = NS). Tumors were more often located in the urethra in men than in women (43 [3.4%] vs 9 [1.8%]; P = 0.034), the trigonum (246 [19.8%] vs 75 [14.9%]; P < 0.001), and the bladder dome or vault (128 [10.3%] vs 37 [7.4%]; P = 0.015). Generally, no difference in survival rate was observed between the sexes; only in the subgroup of muscle-invasive tumors (n = 455) did women have a worse overall survival rate than did men (P = 0.022).Conclusions: Clinical gender differences in bladder cancer appear to have a higher incidence in men than in women. In this analysis, women were older at the age of detection, but had less-invasive and less-aggressive tumors than did men. However, women with muscle-invasive disease had a worse overall survival rate than did men in the same subset.     

Analysis of Sex Differences in Preadmission Management of ST-Segment Elevation (STEMI) Myocardial Infarction

BackgroundMany reports suggest gender disparity in cardiac care as a contributor to the increased mortality among women with heart disease.ObjectiveWe sought to identify gender differences in the management of Myocardial Infarction (MI) Alert–activated ST-segment elevation myocardial infarction (STEMI) patients that may have resulted from prehospital initiation.MethodsA retrospective database was created for MI Alert STEMI patients who presented to the emergency department (ED) of an academic community hospital with 74,000 annual visits from April 2000 through December 2008. Included were patients meeting criteria for an MI Alert (an institutional clinical practice guideline designed to expedite cardiac catheterization for STEMI patients). Data points (before and after initiation of a prehospital alert protocol) were compared and used as markers of therapy: time to ECG, receiving β-blockers, and time to the catheterization laboratory (cath lab). Differences in categorical variables by patient sex were assessed using the χ² test. Medians were estimated as the measure of central tendency. Quantile regression models were used to assess differences in median times between subgroups.ResultsA total of 1231 MI Alert charts were identified and analyzed. The majority of the study population were male (70%), arrived at the ED via ambulance (60.1%), and were taking a β-blocker (67.8%) or aspirin (91.6%) at the time of the ED admission. Female patients were more likely than male patients to arrive at the ED via ambulance (65.9% vs 57.6%, respectively; P = 0.014). The median age of female patients was 68 years, whereas male patients were significantly younger (median age, 59 years; P < 0.001). The proportion of patients currently taking a β-blocker or low-dose aspirin did not vary by gender. Overall, 78.2% of the MI Alert patients arriving at the ED were MI2 (alert initiated by ED physician), and this did not vary by gender (P = 0.33). A total of 1064 MI Alert patients went to the cath lab: 766 male patients (88.9%) and 298 female patients (80.8%). Overall, the median time to cath lab arrival was 79 minutes for men and 81 minutes for women (P = 0.38). Overall, the median time to cath lab arrival significantly decreased from MI1 to MI3, (P_trend < 0.001). For prehospital-initiated alerts (MI3), the median time to cath lab arrival was the same for men and women (64 minutes; P = 1.0). For hospital-initiated alerts, time to cath lab arrival was 82 minutes for male patients and 84 minutes for female patients (P = 0.38). Prehospital activation of the process decreased the time to the cath lab by 19 minutes (P < 0.001; 95% CI, 13.2–24.8).ConclusionNo significant gender differences were apparent in the STEMI patients analyzed, whether the MI Alert was initiated in the ED or prehospital initiated. Initiating prehospital-based alerts significantly decreased the time to the cath lab.     

Effects of a selectively bred novelty-seeking phenotype on the motivation to take cocaine in male and female rats

Background

Although colorectal cancer (CRC) is generally not considered to be a hormone-dependent malignancy, several sex-related differences in incidence, molecular characteristics and survival have been reported. Epidemiological studies have consistently shown that increased exposure to female sex hormones is associated with a lower risk of CRC in women, and cyclin D1, an important downstream effector in estrogen-mediated signaling, is commonly activated in CRC. In this study, we analyzed the prognostic significance of cyclin D1 expression in CRC, with particular reference to sex-related differences, in tumors from a large, prospective, population-based cohort.

Methods

Using tissue microarrays and immunohistochemistry, the fraction and intensity of cyclin D1 expression was evaluated in 527 incident CRC cases from the Malmö Diet and Cancer Study. The χ² and Spearman's rho (ρ) tests were used for comparison of cyclin D1 expression and relevant clinicopathological characteristics. Kaplan-Meier analysis and Cox proportional hazards modeling were used to assess the effect of cyclin D1 expression on cancer-specific survival (CSS) in univariate and multivariate analysis, adjusted for established prognostic factors.

Results

Cyclin D1 intensity was significantly lower in male compared with female CRC (P = 0.018). In the full cohort, cyclin D1 expression was associated with a significantly prolonged CSS (hazard ratio (HR) = 0.69; 95% CI 0.49 to 0.96, P = 0.026) but subgroup analysis according to gender revealed a strongly accentuated prognostic effect of cyclin D1 in male CRC (HR = 0.48; 95% CI 0.31 to 0.74, P < 0.001), which was in contrast to female CRC, where cyclin D1 was not prognostic (HR = 1.05; 95% CI 0.62 to 1.78, P = 0.864) (P _interaction = 0.024). The prognostic value of cyclin D1 was not retained in multivariate analysis, either in the full cohort or in male CRC.

Conclusions

Cyclin D1 expression is strongly associated with prolonged survival in male CRC. These findings not only support an important role for cyclin D1 in colorectal carcinogenesis, but also add further weight to the accumulating evidence that CRC is indeed a hormone-dependent malignancy, for which prognostic and treatment-predictive molecular biomarkers should be evaluated differently in women and men.     

Peri-operative blood transfusion for resected colon cancer: Practice patterns and outcomes in a population-based study

Background & objectivesLiterature suggests that peri-operative blood transfusion among patients with resected colon cancer may be associated with inferior long-term survival. The study objective was to characterize this association in our population.MethodsThis is a retrospective cohort study using the population-based Ontario Cancer Registry (2002–2008). Pathology reports were obtained for a 25% random sample of all cases and constituted the study population. Log binomial regression was used to identify factors associated with transfusion. Cox proportional hazards model explored the association between transfusion and cancer specific survival (CSS) and overall survival (OS).ResultsThe study population included 7198 patients: 18% stage I, 36% stage II, 40% stage III, and 6% stage IV. Twenty-eight percent of patients were transfused. Factors independently associated with transfusion included advanced age (p < 0.001), female sex (p < 0.001), greater comorbidity (p < 0.001), more advanced disease (p < 0.001) and open surgical resection (p < 0.001). Transfusion was associated with inferior CSS (HR 1.51, 95% CI 1.38–1.65) and OS (HR 1.52, 95% CI 1.41–1.63), after adjusting for important confounders.ConclusionsPeri-operative transfusion rates among patients with colon cancer have decreased over time. Transfusion is associated with inferior long-term CSS and OS.     

Effects of locoregional radiotherapy in de novo metastatic nasopharyngeal carcinoma: A real-world study

BackgroundTo evaluate the value of locoregional radiotherapy (LRRT) in de novo metastatic nasopharyngeal carcinoma (dmNPC) and identify predictive factors for additional LRRT after palliative chemotherapy (PCT).MethodsOverall survival (OS) was the primary endpoint. Patients who underwent PCT and LRRT were categorized as the PCT+LRRT group; patients who only received palliative chemotherapy were categorized as the PCT group. Oligometastatic diseases (OMD) was defined as ≤5 metastatic lesions and ≤2 metastatic organs.ResultsA total of 168 patients were included for this study. The median OS of patients in the PCT+LRRT group was significantly higher than those in the PCT group (57 months vs. 22 months, P<0.001). Multivariate analyses (MVA) showed that LRRT (HR=0.533, 95% CI: 0.319–0.889, P = 0.016) and OMD (HR=0.548, 95% CI: 0.331–0.907, P = 0.019) were independent prognostic factors for dmNPC. Furthermore, Kaplan–Meier analyses showed that the 3-year OS of patients who received LRRT was significantly better than those who did not receive LRRT in the OMD subgroup (66.3% vs. 25.2%, P<0.001). While, the 3-year OS of patients who received LRRT and without LRRT was no different in the polymetastatic disease (PMD) subgroup (38.9% vs.11.5%, P = 0.115). MVA showed that LRRT was a favorable prognosticator in the OMD subgroup (HR=0.308, 95% CI: 0.159–0.598; P<0.001), and not a favorable prognosticator in the PMD subgroup (HR=0.510, 95% CI: 0.256–1.014, P = 0.055).ConclusionsLRRT has the potential to prolong OS in NPC patients with de novo OMD. These results suggest that OMD is a potential indicator for filtering beneficiaries from LRRT.     

Parathyroidectomy Is Associated With Reversed Nondipping Heart Rate That Impacts Mortality in Chronic Kidney Disease Patients

ObjectiveNondipping heart rate (HR), defined as a night/day HR ratio >0.90, has been associated with increased mortality in epidemiologic studies. However, its prognostic value in stage 5 chronic kidney disease (CKD5) patients and the effects of parathyroidectomy (PTX) on nondipping HR remain unknown.MethodsThis case-control study of 162 healthy controls and 502 CKD5 patients was performed between 2011 and 2018, in which CKD5 patients were further divided into non-PTX (n = 186) and severe secondary hyperparathyroidism (SHPT) with PTX (n = 316) subgroups. Each participant underwent 24-hour Holter monitoring for HR ratio. Mortality was followed up in CKD5 patients (median time: 46.0 months).ResultsThe HR ratio in CKD5 patients was higher than in controls (0.92 ± 0.08 vs 0.81 ± 0.08, P <.001), associated with a 44% increase in mortality risk per 0.1 increment (hazard ratio, 1.44; 95% CI: 1.02-2.03; P =.04), and was positively related to serum intact parathyroid hormone levels (P <.001). PTX reversed nondipping HR in SHPT patients (n = 50, median time: 6.3 months, P <.001). Survival probabilities for PTX (n = 294) were better than non-PTX (n = 47) (hazard ratio, 0.31; 95% CI: 0.14-0.67; P <.01) in SHPT patients (serum intact parathyroid hormone >500.0 pg/mL).ConclusionCKD5 patients displayed a nondipping HR pattern, which is a prognostic marker of all-cause mortality. PTX for SHPT patients was associated with a reversal in nondipping HR ratio, which may mediate a better outcome.     

Prognostic and clinical significance of focal adhesion kinase expression in breast cancer: A systematic review and meta-analysis

BackgroundThe prognostic significance of focal adhesion kinase (FAK) in breast cancer remains controversial. Here, we conducted a meta-analysis to explore the prognostic value of FAK expression in breast cancer.Materials and methodsPossible prognostic significance of protein or mRNA expression of FAK in breast cancer was investigated with searches of electronic databases for relevant publications. Pooled hazard ratios (HRs) and odds ratios (ORs) with 95% confidence intervals (CIs) were extracted from eligible studies.ResultsA total of eight eligible studies which included 2604 participants were analyzed in this meta-analysis. Increased expression of FAK protein was found to significantly correlate with shorter overall survival (OS) (HR = 1.43, 95% CI: 1.12–1.83; P = 0.004), and not with disease-free survival (HR = 1.31, 95% CI: 0.92–1.85; P = 0.14). Elevated FAK protein expression was also associated with negative estrogen receptor (ER) expression (OR, 1.34; 95% CI, 1.06–1.68; P = 0.01), negative progesterone receptor (PR) expression (OR, 1.54; 95% CI, 1.22–1.93; P < 0.001), positive human epidermal growth factor receptor 2 (HER2) expression (OR, 1.64; 95% CI, 1.28–2.09; P < 0.001), triple-negative breast cancer (TNBC) (OR, 1.57; 95% CI, 1.14–2.17; P = 0.006), high nuclear grade (OR, 1.70; 95% CI, 1.05–2.78; P = 0.03), high Ki-67 expression level (OR, 2.87; 95% CI, 1.94–4.24; P < 0.001), and positive p53 status (OR, 2.28; 95% CI, 1.58–3.29; P < 0.001).ConclusionOur meta-analysis identifies an association between increased FAK protein expression and worse OS among breast cancer patients. Moreover, enhanced FAK expression is associated with negative ER expression, negative PR expression, positive HER2 expression, TNBC, high nuclear grade, high Ki-67 expression level, and positive p53 status in breast carcinoma.     

Gender differences in self-rated health,quality of life,quality of care,and metabolic control in patients with diabetes

Background: Because the projected increase in the number of diabetic patients is expected to strain the capabilities of health care providers worldwide, we are challenged to find ways of reducing the burden of diabetes. Maintaining and improving health-related quality of life (QoL) for diabetic patients may be viewed as public health goals.Objective: The aim of this cross-sectional study was to compare different aspects of health, QoL, and quality of care (QoC) between men and women with diabetes as a basis for planning and managing diabees care.Methods: All patients in 2 age groups (aged 20–30 years [younger age group] and aged 50–60 years [middle-aged group]) who were registered with the Department of Endocrinology, Metabolism, and Diabetes at Karolinska University Hospital, Stockholm, Sweden, in October 2004, were recruited for a survey. Questions were included about self-rated health (SRH), QoL, QoC, diabetes-related worries, occupational status, physical activity level, living arrangements, and educational background. Glycosylated hemoglobin (HbA_1c) values were obtained from medical records.Results: Of the 223 eligible patients (109 men, 114 women) in the younger age group, 49 men and 74 women responded to the questionnaire; of the 300 eligible patients (170 men, 130 women) in the middle-aged group, 120 men and 93 women responded. Middle-aged women rated their mental well-being and QoL as worse compared with men (P < 0.001 and P < 0.05, respectively). In both age groups, women reported more diabetes-related worries and less ability to cope (P < 0.05 for the younger age group and P < 0.001 for the middle-aged group for both variables), thus the differences were more marked for middleaged women. Although there were no gender differences in metabolic control, middle-aged women reported less satisfaction with diabetes care (P < 0.001). Higher HbA_1c was related to worse SRH in both men and women when analyzing the age groups together (P < 0.05). This association was most prominent in young women, in whom having more diabetes-related worries was also related to higher HbA_1c (P < 0.01).Conclusion: In this study, women with diabetes appeared to have worse QoL and mental well-being compared with men with diabetes. Therefore, identifying strategies to improve SRH and QoL among diabetic patients, especially among women, is of great importance.     

Contemporary trends of pelvic lymph node dissection at radical cystectomy for urothelial carcinoma of urinary bladder and associated cancer specific mortality and complications: comparison between octogenarian versus younger patients

BackgroundWe analysed contemporary pelvic lymph node dissection (PLND) trend during radical cystectomy (RC) for urothelial carcinoma of urinary bladder (UCUB), as well as PLND association with cancer specific mortality (CSM) and complications after stratification according to octogenarian vs. younger age.Materials and methodsWithin the SEER and NIS databases, respectively 10,427 (T2 and T3 stages) and 19,203 (all T-stages) RC patients (2004–2015) for UCUB were identified. Univariable and multivariable analyses focused on PLND rates, CSM after inverse probability of treatment weighting (IPTW) adjustment, complication rates, length of stay (LOS) and total hospital charge (THC).ResultsWithin the SEER database, RC and PLND was performed in 9,406 patients (87.4%), 981 (10.4%) octogenarians and 8,227 younger patients (at, respectively, 83 and 89% PLND). PLND rates increased over time in both patients groups (p < 0.05). PLND was independently associated with lower CSM in both age groups (octogenarians: hazard ratio [HR] 0.51, p < 0.001; younger patients: HR 0.56, p < 0.001). Within the NIS database, PLND was marginally higher associated with overall complications in octogenarians than in younger patients (odd ratio [OR]: 1.32 vs. 1.23, both p < 0.001), with longer LOS (OR: 1.20 vs. 1.08, both p < 0.001), higher THC (relative increase: 6933 vs. 4484, both p < 0.001), but not with higher in-hospital mortality.ConclusionsPLND is associated with lower CSM, but its rate lags in octogenarian vs. younger patients. In both age groups, PLND leads to marginally higher complications, longer LOS and higher THC, but not to higher in-hospital mortality.     

The Combination of Platelet Count and Neutrophil Lymphocyte Ratio Is a Predictive Factor in Patients with Esophageal Squamous Cell Carcinoma

OBJECTIVE: The prognostic value of inflammation indexes in esophageal cancer was not established. In this study, therefore, both prognostic values of Glasgow prognostic score (GPS) and combination of platelet count and neutrophil lymphocyte ratio (COP-NLR) in patients with esophageal squamous cell carcinoma (ESCC) were investigated and compared. METHODS: This retrospective study included 375 patients who underwent esophagectomy for ESCC. The cancer-specific survival (CSS) was calculated by the Kaplan-Meier method, and the difference was assessed by the log-rank test. The GPS was calculated as follows: patients with elevated C-reactive protein (> 10 mg/l) and hypoalbuminemia (< 35 g/l) were assigned to GPS2. Patients with one or no abnormal value were assigned to GPS1 or GPS0, respectively. The COP-NLR was calculated as follows: patients with elevated platelet count (> 300 × 10⁹/l) and neutrophil lymphocyte ratio (> 3) were assigned to COP-NLR2. Patients with one or no abnormal value were assigned to COP-NLR1 or COP-NLR0, respectively. RESULTS: The 5-year CSS in patients with GPS0, 1, and 2 was 50.0%, 27.0%, and 12.5%, respectively (P < .001). The 5-year CSS in patients with COP-NLR0, 1, and 2 was 51.8%, 27.0%, and 11.6%, respectively (P < .001). Multivariate analysis showed that both GPS (P = .003) and COP-NLR (P = .003) were significant predictors in such patients. In addition, our study demonstrated a similar hazard ratio (HR) between COP-NLR and GPS (HR = 1.394 vs HR = 1.367). CONCLUSIONS: COP-NLR is an independent predictive factor in patients with ESCC. We conclude that COP-NLR predicts survival in ESCC similar to GPS.     

Clinical Utility of Waist Circumference in Predicting All‐cause Mortality in a Preventive Cardiology Clinic Population: A PreCIS Database Study

Although obesity is a risk factor for mortality, it is unclear whether waist circumference (WC) is a better predictor of mortality than BMI in a clinical setting of patients at high risk for coronary artery disease (CAD). Thus, we compared the association between WC and BMI with all‐cause mortality in relation to traditional CAD risk factors in a high‐risk cohort. Study population included 5,453 consecutive new patients seen between 1996 and 2005 for management of CAD risk factors in a preventive cardiology clinic. Mortality was determined from the Social Security Death Index. There were 359 deaths over a median follow‐up of 5.2 years. Mortality was greater in high (>102 cm in men and >88 cm in women) vs. normal WC in both genders (P < 0.01). The unadjusted Cox proportional hazard ratio (HR) for continuous WC (per cm) was 1.02 (P < 0.001) in both genders and remained significant after adjustment for CAD risk factors (HR = 1.01 in men, HR = 1.03 in women, both P < 0.05). BMI did not associate statistically with mortality. WC associated with diabetes mellitus (DM) and CAD prevalence (P < 0.001). BMI associated only with DM (P < 0.001) and this association disappeared when WC was added to the model. We conclude that WC is an independent predictor of all‐cause mortality in a preventive cardiology population. These data affirm the clinical importance of WC measurements for mortality, DM, and CAD risk prediction and suggest that obesity‐specific interventions targeting WC in addition to traditional risk factor management may favorably impact these outcomes.     

Gender- and age-related outcomes of cardiac resynchronization therapy: A pilot observational study

Background: Cardiac re synchronization therapy (CRT) has been reported to improve clinical status and survival, and shorten hospitalization rates, in patients with heart failure (HF). However, questions remain regarding the success of CRT in different subgroups of patients with HEObjective: We assessed whether CRT response was related to gender or age in patients with HE.Methods: In a longitudinal observational study, patients with severe HF (New York Heart Association [NYHA] class III or IV, left ventricular ejection fraction [LVEF] ≤35%, and QRS duration >120 ms with left bundle branch block configuration) were enrolled. Clinical electrophysiologic and echocardiographic evaluations were performed before, and 3 and 6 months after, CRT implantation.Results: A total of 65 Iranian patients (50 men, 15 women; mean [SD] age, 60.3 [10.3] years; baseline NYHA class, 3.1 [0.36]; QRS duration, 144 [14] ms; LVEF, 21% [7.3%]; left ventricular end-diastolic diameter (LVEDD), 6.8 [0.56] mm) were evaluated. NYHA class, QRS duration, LVEF, and LVEDD were significantly improved at 3- and 6-month follow-ups both in patients aged ≤60 years and in those aged >60 years (P < 0.001, except for aged ≤60 years after 3-month follow-up [P = 0.002]). All these parameters were significantly improved in men at 3- and 6-month follow-ups (P < 0.001). NYHA class (P = 0.002), QRS duration (P = 0.001), LVEF (P = 0.013 at 3 months and <0.001 at 6 months), and LVEDD (P = 0.007 at 3 months and <0.001 at 6 months) also were significantly improved in women. At 3- and 6-month follow-ups, there were no significant differences in improvement of these factors between the 2 age groups of patients.Conclusion: CRT response in these patients with HF did not appear to be gender or age related at 3- and 6-month follow-ups in this small observational study. Confirmation of these findings by larger studies is needed.     

Effect of Age on Survival Outcome in Operated and Non-Operated Patients with Colon Cancer: A Population-Based Study

Objective

To know the effect of age on survival outcome in operated and non-operated patients with colon cancer.

Methods

From the Surveillance, Epidemiology, and End Results database, we identified 123,356 patients with colon cancer who were diagnosed between 1996 and 2005, grouped them as older or younger than 40 years and analyzed their 5-year cancer-specific survival (CSS) data, along with some risk factors, using Kaplan–Meier methods and multivariable Cox regression models.

Results

The younger group had significantly higher pathological grades (P<0.001), more mucinous and signet-ring histology (P<0.001), advanced AJCC stage (P<0.001), and were more likely to undergo surgery (P<0.001). For surgically treated patients, age did not significantly affect 5-year CSS (younger: 66.7%; older: 67.3%; P = 0.86). Further analysis showed that age was an independent prognostic factor in stage I–IV disease (stage I: P = 0.001; P<0.001 for stages II–IV, in both uni- and multivariate analyses), but not for patients with unknown disease stage (P = 0.52). For non-surgically treated patients, age significantly affected 5-year CSS (younger: 16.2%; older: 12.9%; P<0.001) in univariate analysis; and was an independent prognostic factor (P<0.001) in multivariate analysis.

Conclusion

The CSS rate for younger CC patients was at least as high as for older patients, although they presented with higher proportions of unfavorable factors and more advanced disease.     

Functional dyspepsia affects women more than men in daily life: A case-control study in primary care

Background: Little is known about possible gender differences among patients with functional dyspepsia (FD). Few studies have measured health-related quality of life (HRQoL) in patients with FD using a population-based control group as a reference.Objectives: This study aimed to determine the degree of HRQoL impairment among patients with FD, to assess the self-reported health impact resulting from the disease, and to analyze any gender differences.Methods: A questionnaire that included the HRQoL Short Form 36 (SF-36) Health Survey, Hospital Anxiety and Depression Scale, and other measurements was mailed to patients with FD identified from medical records. The control group was randomly selected from the general population in the same geographical area. Responses to the SF-36 were transferred to a standard scale ranging from 0 (the worst possible score) to 100 (the best possible score).Results: Responders were assigned to 2 gender-specific subgroups, each with 88 patients with FD and 344 randomly matched controls, all aged 18 to 65 years. Compared with the controls, the HRQoL of patients with FD was impaired in all SF-36 dimensions except one-role limitations caused by emotional problems. Female patients with FD had a significantly lower SF-36 score in the physical functioning dimension than did male patients (82.4 vs 90.5, respectively; P < 0.01). Both groups of patients with FD had impaired HRQoL compared with their respective control group in the dimensions of bodily pain (women: 69.3 vs 80.6, P < 0.001; and men: 75.8 vs 84.8, P < 0.001) and general health (women: 62.0 vs 75.6, P < 0.001; and men: 70.6 vs 78.6, P < 0.001). Additionally, women with FD had significant impairment compared with their respective control group in the dimensions of physical functioning (82.4 vs 89.3; P < 0.01) and physical role limitations (72.1 vs 85.9; P < 0.001). Depression was significantly more common among male patients with FD than among male controls (6.8% vs 2.0%, respectively; P < 0.05). More gastrointestinal comorbidity was reported among patients of both sexes compared with controls.Conclusions: This population-based case-control study reported HRQoL impairment overall among patients with FD. This impairment was more apparent in female patients than in female controls. Females with FD tended to be more negatively affected in their daily life than their male counterparts. These gender differences should be investigated further in future studies.     

Age-Dependent Influence of Gender on the Association Between Obesity and a Cluster of Cardiometabolic Risk Factors

BackgroundObesity is a main risk factor in metabolic syndrome. Gender is known to influence the risk of obesity and other cardiovascular risk factors. However, it remains to be determined whether there is a gender-specific difference in the relationship between obesity and accumulation of other cardiometabolic risk factors such as hypertension, dyslipidemia, and diabetes.ObjectiveThe aim of this study was to determine whether the association between obesity and a cluster of other cardiometabolic risk factors is modified by gender.MethodsThe subjects were 17,791 Japanese men and women who were divided into younger (35–40 years) and older (60–70 years) age groups. The relationships between obesity (body mass index [BMI] ≥25 kg/m² or waist-to-height ratio [WHtR] ≥0.5) and multiple cardiometabolic risk factors (≥2 of the risk factors of high blood pressure, dyslipidema, and hyperglycemia) were compared between men and women in each age group.ResultsIn the younger group, the crude odds ratios (ORs) for multiple cardiometabolic risk factors in obese versus nonobese subjects were significantly higher in women than in men (BMI: 6.23 [range, 5.53–7.02] in men vs 16.63 [range, 12.37–22.37] in women, P < 0.01; WHtR: 6.04 [range, 5.36–6.81] in men vs 9.77 [range, 7.14–13.37] in women, P < 0.01), whereas this difference was not found in the older group (BMI: 3.03 [range, 2.69–3.42] in men vs 2.92 [range, 2.33–3.67] in women P = 0.076; WHtR: 3.11 [range, 2.78–3.47] in men vs 2.50 [range, 2.02–3.09] in women, P < 0.05). On multivariate logistic regression analysis, the ORs for multiple cardiometabolic risk factors after adjusting for age, smoking, alcohol consumption, and regular exercise in subjects with versus subjects without a large waist circumference tended to be higher in women than in men in the younger group but not in the older group. The ORs of the interaction term consisting of gender and each adiposity index for multiple cardiometabolic risk factors were significantly higher than a reference level of 1.00 in the younger group (BMI: 2.68 [range, 1.95–3.69], P < 0.01; WHtR: 1.62 [range, 1.16–2.27], P < 0.01) but not in the older group (BMI: 0.95 [range, 0.74–1.23], P = 0.712; WHtR: 0.80 [range, 0.63–1.02], P = 0.066).ConclusionThe results suggest that the association between obesity and a cluster of cardiometabolic risk factors is stronger in women than in men, and this gender-specific difference exists in younger (35–40 years) but not in older (60–70 years) individuals.
