Decrease with aging of the microcirculatory function of the lumbar vertebral marrow preceding the loss of bone material density and the onset of intervertebral discal degeneration: A study about the potential cause

ObjectiveUsing a dynamic computed tomographic perfusion (CTP) imaging method to explore the age-related distribution of the microcirculation perfusion function in the vertebral marrow, the bone material density (BMD), and the intervertebral discal degeneration (IDD). Further, to discuss a possible causation relationship between them.MethodsOne hundred and eighty-six people were randomly enrolled by stratified sampling and grouped by age: ≤15, 16–25, 26–35, 36–45, 46–55, 56–65, 66–75, and ≥76 years old. The average CTP and BMD of the third and fourth lumbar vertebrae marrow were measured and the IDD incidence of the third-fourth vertebrae was assessed. The temporal–spatial distribution patterns of the age-related changes of the CTP, BMD, and IDD were described, and the correlations between them were calculated.ResultsThe microcirculatory perfusion function of the vertebral marrow develops to maturity by 25 years and is maintained until age 35, then declines with aging. The BMD grew to a peak from 26 to 45 years old, then decreased yearly. The IDD showed a sudden increase after 45 years of age. The CTP [BF (r = 0.806, P = 0.000), BV (r = 0.685, P = 0.005) and PMB (r = 0.619, P = 0.001)] showed strong positive correlations and CTP [TTP (r = −0.211, P = 0.322) and MTT (r = −0.598, P = 0.002)] showed negative correlations with BMD. The CTP [BF (r = −0.815, P = 0.000), BV (r = −0.753, P = 0.000) and PMB (r = −0.690, P = 0.000)] had strong negative correlations, and CTP [TTP (r = 0.323, P = 0.126) and MTT (r = 0.628, P = 0.001)] had positive correlations with the incidence of IDD.ConclusionThe decrease with aging of the microcirculatory perfusion in the lumbar vertebral marrow preceded, and is a potential causative factor for the loss of BMD and the onset of IDD.     

Maternal and neonatal outcomes in multiple pregnancy: A multicentre study in the Beijing population

ObjectiveTo compare the adverse maternal and neonatal outcomes of multiple pregnancy and singleton pregnancy from multiple medical centers in Beijing.MethodsData concerning maternal and neonatal adverse outcomes in multiple and singleton pregnancies were collected from 15 hospitals in Beijing by a systemic cluster sampling survey conducted from 20 June to 30 November 2013. The SPSS software (version 20.0) was used for data analysis. The χ² test was used for statistical analyses.ResultsThe rate of caesarean deliveries was much higher in women with multiple pregnancies (85.8%) than that in women with singleton pregnancies (42.6%, χ² = 190.8, P < 0.001). The incidences of anemia (χ² = 40.023, P < 0.001), preterm labor (χ² = 1021.172, P < 0.001), gestational diabetes mellitus (χ² = 9.311, P < 0.01), hypertensive disorders (χ² = 122.708, P < 0.001) and post-partum hemorrhage (χ² = 48.550, P < 0.001) was significantly increased with multiple pregnancy. In addition, multiple pregnancy was associated with a significantly higher rate of small-for-gestational-age infants (χ² = 92.602, P < 0.001), low birth weight (χ² = 1141.713, P < 0.001), and neonatal intensive care unit (NICU) admission (χ² = 340.129, P < 0.001).ConclusionsMultiple pregnancy is a significant risk factor for adverse maternal and neonatal outcomes in Beijing. Improving obstetric care for multiple pregnancy, particularly in reducing preterm labor, is required to reduce the risk to mothers and infants.     

Study on the correlation between the concentration of plasma lipoprotein-associated phospholipase A2 and coronary heart disease

ObjectiveThis study explores the correlation between plasma lipoprotein-associated phospholipase A2 (Lp-PLA2) and coronary heart disease (CHD) by comparing the level of plasma Lp-PLA2 in the plasma of patients with different types of CHD.MethodsBlood samples were collected from 56 patients diagnosed with CHD by the Department of Cardiology of the First People''s Hospital of Foshan and 34 healthy subjects from February 2013 to January 2014. We measured the concentration of plasma Lp-PLA2 and determined the levels of total cholesterol (Tch), triglyceride (TG), apolipoprotein A1 (Apo-A1), apolipoprotein B (Apo-B), high density lipoprotein-cholesterol (HDL-c), low density lipoprotein-cholesterol (LDL-c), lipoprotein a (Lp(a)), glucose (Glu), and high-sensitivity C-reactive protein (hs-CRP). The concentration of plasma Lp-PLA2 in the healthy control group and each subgroup of CHD patients were compared and analyzed for correlations of plasma Lp-PLA2 between the patients in different CHD subgroups and several laboratory indicators.ResultsThe concentration of plasma Lp-PLA2 in each subgroup of CHD was significantly higher than in the control group (P < 0.05). The concentration of Lp-PLA2 in the unstable angina pectoris (UAP) group and acute myocardial infarction (AMI) group were significantly higher than in the stable angina pectoris (SAP) group (P < 0.05), and the concentration of plasma Lp-PLA2 in the AMI group was significantly higher than in the UAP group (P < 0.05). The concentration of plasma Lp-PLA2 in the CHD group merely showed a positive correlation (r = 0.493, P < 0.05) with the hs-CRP group, but the levels of Tch, TG, Apo-A1, Apo-B, HDL-c, LDL-c, Lp(a) and Glu did not.ConclusionsThe concentration of plasma Lp-PLA2 in patients with CHD was higher than that in the control group. The concentration of plasma Lp-PLA2 in the subgroups of CHD patients varied greatly from each other. The inflammatory response of atherosclerosis might be resulted from the synergy of plasma Lp-PLA2 and hs-CRP.     

Different position from traditional left lateral for colonoscopy? A meta-analysis and systematic review of randomized control trials

Background: Colonoscopy requires the intubation of the cecum for screening of colorectal diseases. The conventional position used for colonoscopy is the left lateral position (LLP). However, alternative positions have also been utilized to enhance the success of intubation. Thus, the aim of this study was to perform a meta-analysis of the different positions to determine the effectiveness of the individual positions for successful colonoscopy.Methods: Medline, Embase and Cochrane trials electronic databases were searched for studies on colonoscopy positions. The primary outcome was defined as the cecal intubation rate. Pooled risk ratios (RR) and 95% confidence intervals (CI) for the rates of cecal intubation were estimated. Secondary outcomes such as the cecal intubation time and adenoma detection rate were further analyzed qualitatively.Results: After reviewing 644 identified records, 7 randomized control trials (RCT) studies were included. No significant difference was observed in either comparisons, between the LLP vs. supine position (SP) (RR = 1.01, 95% CI, 0.98 to 1.04,P = 0.55) or the LLP vs. prone position (PP) (RR = 1.02, 95% CI, 0.98 to 1.06,P = 0.27).Conclusions: Amidst available literature, the use of other positions can be considered when performing colonoscopy. These further highlights that the existential practice is based predominantly on familiarity instead of evidence-based-research.     

National trends in insulin resistance and β-cell dysfunction among adults with prediabetes: NHANES 2001–2016

BackgroundInsulin resistance is the central abnormality and mechanism underlying the progression of cardiometabolic-based chronic diseases. This study aimed to evaluate the trends in insulin resistance and β-cell dysfunction from 2001 to 2016 among US adults with undiagnosed diabetes, prediabetes, and normal glucose regulation and to provide sex-specific information using data from National Health and Nutrition Examination Surveys (NHANES) 2001–2016.MethodsData from 14,481 participants aged over 20 years from 8 consecutive 2-year cross–sectional cycles of the NHANES from 2001 to 2016 were used. Updated homoeostasis model assessment 2 (HOMA2: HOMA2%B for β-cell function and HOMA2IR for insulin resistance) was used as a surrogate measure. We defined the upper sex-specific tertile of HOMA2IR as insulin resistance and the lower corresponding tertile of HOMA2%B as low β-cell function.ResultsIn both sexes with undiagnosed diabetes, HOMA2%B (men, P_trend = 0.118; women, P_trend = 0.184) and HOMA2IR (men, P_trend = 0.710; women, P_trend = 0.855) remained stable over time. In the prediabetes group, both sexes exhibited significant increasing trends in HOMA2%B (men, P_trend < 0.010; women, P_trend < 0.010) and HOMA2IR (men, P_trend < 0.010; women, P_trend < 0.050). Adjusting for waist circumference mildly attenuated the trend in HOMA2IR and insulin resistance in men (P_trend < 0.010), but it resulted in no significance in women (P_trend = 0.196). In regard to normal glucose regulation, both sexes presented significant decreasing trends in low β-cell function (men, P_trend < 0.050; women < 0.010) and attenuated trends in insulin resistance (men, P_trend = 0.196; women, P_trend = 0.121).ConclusionsOver 16 years, insulin resistance demonstrated an increasing trend in adult US population with prediabetes, while β-cell function showed a compensatory increasing trend. Identifying people with prediabetes early and focusing on reducing insulin resistance as the intervention core, especially controlling central obesity, might increase the opportunity for cardiovascular and diabetes risk reduction.Keyterms: Insulin resistance, β cell dysfunction, Diabetes mellitus, Prediabetes     

A novel method to rapidly calculate the urea clearance index and urea reduction rate based on parameters obtained during hemodialysis

Background: The efficacy of hemodialysis (HD) is closely associated with patient survival time and quality of life. The classical method (CLM) to calculate the urea clearance index (Kt/V) and urea reduction rate (URR) requires multiple blood tests. A novel method that may be used as a noninvasive alternative to CLM is required.Methods: Based on the urea kinetic model, a new method, named the "assessment method" (ASM), was established to calculate blood urea nitrogen after HD, based on parameters obtained during HD. The consistency of the Kt/V and URR values between the ASM and CLM was evaluated in 41 patients from the China-Japan Friendship Hospital between September 2017 and December 2018.Results: Forty-one patients (24 males and 17 females;mean age, 55.7 ± 14.2 years) undergoing regular HD in our hospital were randomly selected for this study. The blood flow rate was 244.5 ± 19.6 mL/min and the dialysate flow rate was 500 mL/min. We obtained Kt/V (CLM = 1.40 ± 0.06, ASM = 1.37 ± 0.07) and URR (CLM = 68.6 ± 6.4%, ASM = 67.7 ± 7.2%) values. Pairedt-test indicated no significant differences between the ASM- and CLM-derived values. The intraclass correlation coefficients were 0.907 and 0.916 for Kt/V and URR, respectively. Similarly, Bland-Altman plots suggested good concordance between the 2 methods.Conclusions: The Kt/V and URR values calculated using the ASM and CLM were in significant agreement, and both can be used to effectively assess the adequacy of HD in patients undergoing maintenance HD. The ASM is an effective, rapid, inexpensive, and noninvasive alternative to the CLM for obtaining Kt/V and URR values. The ASM has good potential for clinical application, particularly for patients in areas of low socioeconomic status.     

Clinical observation and therapeutic evaluation of intravenous pump of recombinant human endostatin combined with TP regimen in treating patients with advanced ovarian cancer

ObjectivesTo observe the curative effects and adverse reactions of recombinant human (rh)-endostatin injection combined with a TP regimen for treating patients with advanced ovarian cancer.MethodsFifty-four patients with pathologically confirmed ovarian cancer were randomly divided into a combined treatment (intravenous pump of rh-endostatin + TP regimen) group and a control (single chemotherapy) group, twenty-seven patients in each group. All patients were given a conventional CT examination. The level of vascular endothelial growth factor (VEGF), the size of tumor before treatment, after 2 cycles and after 4 cycles of treatment were determined for the comparison of curative effects and adverse reactions.ResultsThe effective rate was 37.0% (10/27) and disease control rate was 63.0% (17/27) in the combined treatment group after 2 cycles of treatment. The effective rate was 25.9% (7/27) and disease control rate was 63.0% (17/27) in the control group. The comparison between these two groups showed no significant differences (P > 0.05). The effective rate was 63.0% (17/27) and disease control rate was 92.6% (25/27) in the combined treatment group after 4 cycles of treatment. The effective rate was 29.6% (8/27) and disease control rate was 63.0% (17/27) in the control group. The effective rate and disease control rate between these two groups after 4 cycles of treatment showed significant differences (P < 0.05). The incidences of cardiovascular toxicity, myelosuppression, sore muscles and joints, alopecia and gastrointestinal reaction was not significantly different between two groups (P > 0.05).ConclusionThe pump delivery of rh-endostatin can down-regulate the expression of VEGF in ovarian cancer and has the better curative effect and slighter adverse reactions.     

Polymer-free versus permanent polymer drug eluting stents in coronary artery disease: A meta-analysis of 10 RCTs with 6575 patients

BackgroundPermanent polymer drug eluting stents (PP-DES) may induce inflammation of the vessel wall due to the existence of the polymer, which may delay intimal healing. Polymer-free DES (PF-DES) that eliminate the polymeric carrier may potentially lead to safer DES. However, the safety and efficacy of PF-DES remains controversial.MethodsRandomized controlled trials comparing PF-DES with PP-DES were searched in online database including MEDLINE, Excerpta Medica Database (EMBASE) and Cochrane Library. Studies reporting late lumen loss (LLL), all-cause death, myocardial infarction (MI), target lesion revascularization (TLR) and late stent thrombosis (LST) were enrolled and quantitatively analyzed.ResultsTen studies enrolling 6575 patients were included in this meta-analysis. The PF-DES showed a benefit in reducing all-cause death (OR = 0.77, 95% CI: 0.61 to 0.98, P = 0.03) and long-term LLL (weighted mean difference (WMD) −0.16 mm, 95% CI: −0.22 to −0.11 mm, P < 0.001), while no superiority was found in reducing short-term LLL (WMD 0.03 mm, 95% CI: −0.07–0.13 mm, P = 0.57), MI (OR = 1.12, 95% CI: 0.19 to 23.18, P = 0.39), TLR (OR = 1.19, 95% CI: 0.42 to 3.38, P = 0.83) and LST (OR = 0.92, 95% CI: 0.05 to 5.71, P = 0.74).ConclusionPF-DES showed benefits in reducing long-term LLL and mortality compared with PP-DES, but no superiority was found in short-term LLL, MI, TLR and LST. These findings provide a sound basis for the wide application of PF-DES in the future.     

Clinical analysis of retroperitoneoscopic nephroureterectomy for renal tuberculosis

ObjectivesTo explore the feasibility and safety of retroperitoneoscopic nephroureterectomy for kidney tuberculosis.MethodsForty-eight retroperitoneoscopic nephroureterectomies and thirty-five nephroureterectomies for kidney tuberculosis procedures were performed from June 2008 to December 2014. The patients consisted of 53 males and 30 females with a mean age of 36 years (range: 26–51 years). The patients'' data were reviewed and analyzed.ResultsThe retroperitoneoscopic nephroureterectomy procedures were completed successfully in 48 cases with no conversions to open surgery. The mean operating time was 170 minutes (range: 121–258 minutes), the mean blood loss was 110 ml (range: 70–250 ml), and the mean hospital stay was 5.70 days (range: 5–14 days); these were all much less than nephroureterectomy procedures (P < 0.05). A total of five minor complications (10.4%) occurred, injury to the peritoneum was observed in three patients, and infection at the incision site was observed in two patients, there were no obvious difference between the two surgical methods (P > 0.05). Seventy-five patients were followed up, and the average follow-up time was 12.5 months (range: 6–20 months). All the patients recovered without any lesions remaining.ConclusionsThe results of this study indicate that retroperitoneoscopic nephroureterectomy is a feasible, safe, effective, and less invasive treatment modality for treating renal tuberculosis.     

Short- and long-term outcomes of kidney transplants with kidneys lavaged by retrograde perfusion technique

ObjectiveTo evaluate the clinical safety and efficacy of the retrograde perfusion technique in kidney transplantation.MethodsBetween January 2001 and June 2011, 24 cases of kidney transplantation with kidneys perfused using the retrograde perfusion technique due to renal artery variations or injury were selected as the observation group (retrograde perfussion group, RP group). Twenty-two cases of kidney transplantation via conventional perfusion were chosen as the control group (antegrade perfussion group, AP group). There were no statistically significant differences in donor data between the two groups. Cold ischemia time, warm ischemia time, renal perfusion time, amount of perfusion fluid, acute renal tubular necrosis, wound infection, urinary fistula, graft kidney function, and the 1-year, 3-year, and 5-year survival rates for the grafted kidney in both groups were observed and recorded.ResultsThe kidney perfusion time was shorter in the RP group than that in the AP group (3.14 ± 1.00 vs. 5.02 ± 1.15 min, P = 0.030). There were 10 cases of acute renal tubule necrosis in the RP group and 5 in the AP group. The length of hospital stay was 40 ± 14 d in the RP group and 25 ± 12 d in the AP group. The follow-up time was 3.5–8.5 years (mean 6.25 years). The 1-, 3-, and 5-year survival rates for the grafted kidney were 95.8%, 75.5%, and 65.5% in the RP group and 97.1%, 82.5%, and 68.4% in the AP group, respectively (P>0.05).ConclusionsThis study indicates that retrograde perfusion is safe and practicable for cadaveric kidney harvesting and can be regarded as a better alternative or remedial measure for a poorly perfused kidney due to vascular deformity or injury.     

A meta-analysis of the prognosis in patients with breast cancer with ipsilateral supraclavicular lymph node metastasis versus patients with stage IIIb/c or IV breast cancer

ObjectiveTo systematically evaluate the prognosis in patients with breast cancer with ipsilateral supraclavicular lymph node metastasis (SLNM) versus patients with stage IIIb/c or IV breast cancer, so as to provide evidence for clinical practice and research.MethodsComputer retrieval from PubMed, Cochrane Libratory, CNKI (China National Knowledge Infrastructure), CBM and Wanfang Database with the assistance of other retrieval tools. All the studies evaluating the prognosis in patients with breast cancer with ipsilateral supraclavicular lymph node metastasis versus patients with stage IIIb/c or IV breast cancer were collected. Quality assessment was performed for the included data based on the quality assessment criteria appropriate for this study. Meta-analysis was performed using RevMan 5.3 software.ResultsA total of four references (1277 patients) were included. Assessment of influences on prognosis: As compared to the stage IIIb/c group, the 5-year survival rate was slightly lower in the SLNM group (relative risk (RR) 0.79; 95% confidence interval (CI) 0.59–1.06; Z = 1.55, P = 0.12), but there was no statistical significance; in contrast, the 5-year survival rate was significantly increased in the SLNM group as compared to the stage IV group (RR = 2.70; 95%CI: 1.36–5.37; Z = 2.84, P = 0.005). As compared to the stage IIIb/c group, the 5-year disease-free survival rate was lower in the SLNM group (RR = 0.65; 95%CI: 0.40–1.05; Z = 1.75, P = 0.08); however, there was no statistical significance.ConclusionsIn patients with advanced breast cancer receiving combined therapy, the prognosis in patients with breast cancer with ipsilateral SLNM was significantly better than in those with stage IV breast cancer, and slightly worse than those with stage IIIb/c breast cancer. However, with the scarcity and poor quality of these observational studies, the long-term prognosis remains to be further verified in large-sample, high-quality studies.     

Comparison of circumferential pulmonary vein anatomy mapping guided by 3D mapping versus a mesh mapping catheter

ObjectiveCatheter-based pulmonary vein isolation (PVI) is an established therapy for paroxysmal atrial fibrillation. The high-density mesh mapper (HDMM) guides circumferential PV-atrium isolation without the 3D electroanatomic mapping. This study aims to compare circumferential pulmonary vein (CPV) anatomy mapping between guiding by a 3D mapping system and the HDMM.MethodsForty-four consecutive patients with paroxysmal atrial fibrillation were scheduled for a first procedure for PVI. A CPV ostial anatomy map guided by HDMM was set up in the CARTO system while the operator was blinded to the CARTO screen. Then CARTO-guided ipsilateral PV maps were obtained and PVI was performed. This established another set of CPV ostial anatomy maps. The differences between the two mapping images were compared and analyzed.ResultsAll 176 PVs in 44 patients could be mapped by both HDMM and CARTO. About 44.9% of the PV ostial anatomies were generally similar between the two different map images. The average point-to-point straight distance between the HDMM-guided map and the CARTO-guided map was 6.2 ± 1.4 mm. The area of the circumferential right PV (CRPV) in the HDMM map was larger than that in the CARTO map (P = 0.013). After a mean follow-up of 18.3 ± 4.3 months (6–24 months), 72.7% of patients (32/44) were free of atrial arrhythmia without anti-arrhythmic drugs (AADs).ConclusionCompared to the CARTO-guided CPV anatomy image, a highly similar figure could be achieved by mapping guided by the HDMM.

Influence of Tirofiban maintenance duration on patients with acute myocardial infarction treated by percutaneous coronary intervention

ObjectiveTo evaluate the efficacy and short term prognosis of Tirofiban in different treatment duration in patients with acute ST segment elevation myocardial infarction (STEMI) and percutaneous coronary intervention (PCI) combined with intracoronary injection.MethodsA total of 125 patients with acute STEMI were enrolled in this study. They were randomly divided into two groups: control group (n = 61) and Tirofiban group (n = 64). The Tirofiban was used by intracoronary and intravenous administration in Tirofiban group which was randomly divided into three sub-groups according to the duration of Tirofiban by persistent intravenous injection for 12 hours, 24 hours or 36 hours. Thrombolysis in myocardial infarction flow and myocardial perfusion grades were recorded immediately after PCI. The adverse cardiac events and cardiac death within 180 days of PCI, and the adverse effects (hemorrhage and thrombocytopenia) were compared between the two groups and within Tirofiban sub-groups.ResultsGrade 3 in myocardial perfusion was significantly better in Tirofiban group than control group (85.94% vs. 72.13%, P = 0.03) after PCI. There was one cardiac death in control group in 180 days after PCI. The adverse cardiac event rates between two groups was significant difference (16 patients in control group and only 8 in Tirofiban group, P = 0.047). There was no significant difference in incidence of hemorrhage complications and platelet counts between two groups. Nevertheless, hemorrhage complications in the 12- and 24-hour subgroups were less than 36-hour subgroup (P = 0.01).ConclusionsIntravenous Tirofiban treatment reduced the adverse cardiac events and improved short term prognosis without increasing the adverse reactions of the drugs in patients undergoing PCI. The less rate of hemorrhage complication can be achieved in short-duration of Tirofiban by intravenous injection after PCI.     

Lifestyle intervention for gestational diabetes mellitus prevention: A?cluster-randomized controlled study

ObjectiveThe study was to examine whether gestational diabetes mellitus (GDM) can be prevented by early trimester lifestyle counseling in a high-risk population.MethodsFrom September 2012 to January 2013, 1664 pregnancies in the Department of Obstetrics and Gynecology of First Hospital of Peking University were enrolled in the study during their first prenatal care visit before the 8 gestational weeks visit and asked to fill out a questionnaire on GDM risk evaluation. According to the questionnaire and medical records, those with at least one risk factor of GDM were included in the intervention study and randomly allocated to two groups, intervention group and control group. Routine prenatal care was offered, while standardized two-step lifestyle intervention was provided to the intervention group during 6–8 gestational weeks, and at 12–13 gestational weeks, enforcement intervention based on maternal anthropometrics were offered. Both groups were followed until 75 g oral glucose tolerance test (OGTT) testing at 24–28 gestational weeks. The weight gain after intervention and the prevalence of GDM were used to evaluate the effect.Results(1) According to the International Association of Diabetes and Pregnancy Study Groups (IADPSG) criteria, the positive rate of GDM for the intervention group was 17.16% (23/134), lower than the control group which was 23.91% (33/138), P = 0.168. (2) The weight gain during the first and second trimester for the intervention group was (1.38 ± 2.34) kg and (5.51 ± 2.18) kg, lower than in the control group which was (1.41 ± 2.58) kg and (5.66 ± 2.25) kg, (P = 0.905, P = 0.567). (3) Positive rate of GDM for those fasting plasma glucose (FPG) ≥5.1 mmol/L during early pregnancy was 11/36 (30.55%) for the intervention group that was lower than 17/37 (45.95%) for the control group, but the statistical difference was not significant (P = 0.076).ConclusionThe positive rate of GDM could be reduced by a certain amount lifestyle intervention from the beginning of pregnancy. More validated effective intervention should be explored in the high-risk pregnant women.

Potential role of pemetrexed in metastatic breast cancer patients pre-treated with anthracycline or taxane

ObjectivesThis article reviews pharmacology, pharmacokinetic properties, clinical efficacy, and safety in metastatic breast cancer patients, as well as the predictive biomarkers for outcome of treatment with pemetrexed-based regimens.MethodsPubMed, Embase, OVID, and the Cochrane Library databases were searched from the beginning of each database without any limitations to the date of publication. Search terms were ‘‘pemetrexed’’ or ‘‘{"type":"entrez-nucleotide","attrs":{"text":"LY231514","term_id":"1257767600","term_text":"LY231514"}}LY231514’’ or “Alimta”, “metastatic breast cancer”, and “advanced breast cancer”.ResultsThere were 15 studies (n = 1002) meeting our criteria for evaluation. Eight single-agent trials (n = 551) and seven using combinations with other agents (n = 451) were identified that evaluated pemetrexed for use in patients with metastatic breast cancer. Response rates to pemetrexed as a single agent varied from 8% to 31%, and with combination therapy have been reported to be between 15.8% and 55.7%. With routine supplementation of patients with folic acid, dexamethasone, and vitamin B₁₂, the toxicity profile of these patients was mild, including dose-limiting neutropenia and thrombocytopenia, as well as lower grades of reversible hepatotoxicity and gastrointestinal toxicity. Expression of thymidylate synthase (TS) and other biomarkers are associated with the prognosis and sensitivity for pemetrexed in breast cancer.ConclusionPemetrexed has shown remarkable activity with acceptable toxicities for treatment of metastatic breast cancer patients. Translational research on pemetrexed in breast cancer identified biomarkers as well as additional genes important to its clinical activity and toxicity. Further research is needed to clarify the role of pemetrexed in breast cancer treatment in order to guide oncologists.     

Pulmonary rehabilitation for patients with coronavirus disease 2019 (COVID-19)

Who benefits from R0 resection? A single-center analysis of patients with stage Ⅳ gallbladder cancer

ObjectivesMost patients with gallbladder cancer (GBC) present with advanced-stage disease and have a poor prognosis. Radical resection remains the only therapeutic option to improve survival in patients with GBC. This study aimed to analyze the prognostic factors in patients with stage Ⅳ GBC and to identify a subgroup of patients who might benefit from R0 resection.MethodsA total of 285 patients with stage Ⅳ GBC were retrospectively analyzed at our institution from January 2008 to December 2012. Factors potentially influencing the prognosis of GBC after surgery were analyzed by univariate and multivariate analyses.ResultsThe 1-, 3-, and 5-year overall survival rates were 6.6% (15/229), 0.9% (2/229), and 0 (0/229), respectively. Ascites (relative risk [RR] = 1.631, 95% confidence interval [CI]: 1.221–2.180, P = 0.001), pathological grade (RR = 1.337, 95% CI: 1.050–1.702, P = 0.018), T stage (RR = 1.421, 95% CI: 1.099–1.837, P = 0.000), M stage (RR = 1.896, 95% CI: 1.409–2.552, P = 0.000), and surgery (RR = 1.542, 95% CI: 1.022–2.327, P = 0.039) were identified as independent risk factors influencing prognosis. The median survival time (MST) was significantly higher in patients undergoing R0 resection than in those undergoing R1/R2 resection (6.0 vs. 2.7 months; P < 0.001). In subgroup analyses, stage ⅣA patients benefited from R0 resection (MST for R0 vs. R1/R2, 11.0 vs. 4.0 months; P = 0.003), while R0 resection had a significant survival benefit than R1/R2 resection in patient with stage ⅣB GBC without distant metastasis (MST for R0 vs. R1/R2, 6.0 vs. 3.0 months; P = 0.007).ConclusionAscites, pathological grade, T stage, M stage, and surgery were independent risk factors influencing prognosis in patients with stage IV GBC. N2 lymph node metastasis did not preclude curative resection, and radical resection should be considered in patients with stage Ⅳ GBC without distant metastasis once R0 margin was achieved.
